The temporomandibular joint (TMJ) is the area right in front of the ear on either side of the head where the upper jaw (maxilla) and lower jaw (mandible) meet.
The temporomandibular joints are very complex and are made up of muscles, tendons, a disc and bones.You have a temperomandibular joint on each side of your jaw (right and left side). Micro trauma is considered internal, such as grinding the teeth (bruxism) and clenching (jaw tightening).
TMJ pain can usually occur because of unbalanced activity, spasm, or overuse of the jaw muscles. Most patients are quite successful with conventional conservative therapy (such as resting the jaw or night guard).
We are a full service dental practice that specializes in relaxation and cosmetic dentistry services, dental implants, TMJ disorder treatment, periodontal disease treatment, teeth whitening, porcelain crowns and porcelain veneers, and other restorative dental care. This leads to patients having to deal with side effects and occasionally means that a possibly more sinister underlying problem is left untreated.
The irritation or inflammation of the stomach lining is called gastritis and this can be sudden (acute) or develop over a long period (chronic). If chronic gastritis is not treated this may last for a long time interfering in one’s daily activities. It is noted that all people who have gastritis do not have symptoms and this term gastritis is mistakenly used by many to describe any upper abdominal pain or discomfort.
Helicobacter Pylori bacteria that can live in the lining of the stomach can infect the underlying tissue and lead to ulcers and even to stomach cancers in certain people. Generally the body’s defence systems make antibodies that can fight off infection and keep the body healthy.
During a blood test your doctor will check for anaemia where the iron containing substance – haemoglobin - could be diminished if there is bleeding in the stomach. Here a lighted flexible tube with a camera is passed through the mouth into your stomach and the lining is visualized by your doctor. Patients should review their symptoms with their doctors who will then evaluate their condition and advise them on the treatment options.

Diverticulitis is inflammation or infection of small pouches called diverticula that develop along the walls of the intestines. The formation of the pouches themselves is a relatively benign condition known as diverticulosis.
The pouches can develop anywhere on the digestive tract, but they most commonly form at the end of the descending and sigmoid colons located on the left side of the abdomen. They also frequently occur on the first section of the small intestine, although those rarely cause problems.
If you have diverticulosis, you may not even be aware of it because the diverticula are usually painless and cause few symptoms, if any. Fistulas may develop if an infected diverticulum reaches an adjoining organ and forms a connection between them. Not long after the beginning of their terrible civil war Bosnians became aware of, and thoroughly fed up with, fleeting visitors to their country who arrived armed with promises of help and equipped with cameras to record their visit. During the active hostilities immediate assistance was imperative when the day-to-day demands of survival were paramount but there was also a humane duty to help plan the future. My wife and I were soon able to make our first contribution by purchasing a new ultrasound machine that is essential for this type of work 2. Such gratuitous generosity repeatedly occurred as our work continued and the next example was the seminal event in the history of the Charity. It is imperative to carefully monitor seriously ill patients during their hazardous journeys to specialist centres and the first use of Simon’s donation was to purchase mobile oxygen monitors for use in transferring Bosnian patients with critical conditions such as head injuries across territories that were still hostile and where the roads were often rudimentary.
We have been responsive in an International manner with Aid given in Azerbaijan, Bosnia, Sierra Leone, and Afghanistan along with our most recent activity in Pakistan. We responded to the long term Disaster of war where economic and social collapse had occurred. The Aid was certainly of an Emergency nature in Bosnia but most of the work in the Balkans, and more recently in Pakistan, has largely been of a Long term Support in clinical work and medical education. In many ways the more recent work in North West Pakistan encompasses all the aims of IDEALS by allowing us to support a region with major problems derived from years of war and internecine strife. Any Charity is defined by its results and the most efficient way to present IDEALS is to review the work over the years country by country. Without doubt the portrayal of the true horror of the war by the world’s media prevented an even greater catastrophe occurring but with the end of gunfire the attention inevitably decreased.
In fact this was just the time when Bosnia needed continued help from its friends and there was no better way to demonstrate it than by offering assistance in reconstructing the services that had been either destroyed by the hostilities or converted to purely wartime activities.
IDEALS was eminently suited to this task and with a programme of studying developmental dysplasia of the hip already underway and educational visits to the UK by surgeons and anaesthetists either completed or planned it was simple to build on these activities. June 2001: prof gavrankapetanovic and dr s djozic delivering Lectures on their work at edinburgh trauma care conference. In all medical specialities repeated familiarisation with ones subject is essential if a high level of clinical confidence and competence is to be maintained. The remarkable work undertaken by local surgeons during the war was veryb specialised and, during the hostilities, they frequently stated their wish to redevelop the educational levels to match those in the rest of Europe. The donation of numerous books and journals has been a major contribution to Sarajevo and in addition two senior surgeons, Dr Sukrjia Djozic and Professor Ismet Gavrankapetanovic, were sponsored as Fellows of the British Orthopaedic Association with their annual fees paid by personal donation via IDEALS. In addition there have been several visits by Sarajevo surgeons and other medical staff to the UK in order to attend Conferences both as student delegates and to present lectures on their own subjects. IDEALS has also been to the fore in encouraging research and helping its collation for publication. WRIGHTINGTON HIP CENTRE July 1998: Visit by Dr Djozic and Dr Salihefendic for a course on joint prostheses. BOURNEMOUTH TO TRAUMA CARE CONFERENCE June 1999: Visit by Dr Djozic, Salihefendic, Dr M Begovic, Dr V Cengic and Dr H Leto to deliver papers in on subjects related to war time practice in orthopaedics, blood transfusion during a modern siege, resuscitation via emergency thoracotomy and vascular surgery.
TRAUMA CARE CONFERENCE IN EDINBURGH July 2001: Visit by Dr Sukrjia Djozic, Dr Svetlana Djozic and Professor Ismet Gavrankapetanovic. Between February and May 2001: Three lectures on DDH by JPB including detection and treatment and the requirements for a pan Sarajevo research project. June 2001 and summer 2003: Professor Graf an international expert in the field and his assistant were funded by IDEALS to visit Sarajevo to conduct courses and certificate staff for ultrasound detection of DDH. This project was jointly organised between the State Hospital Sarajevo and Kosovo University Clinical Centre.
The initial equipment was purchased as already described and a computer, printer and CD recorder were donated via IDEALS the total cost being £15000. DDH is a significant condition in early child hood that requires increasing intervention if delay occurs in diagnosis. If the diagnosis is delayed for several months, lengthy in-patient treatment is required and often extensive surgical intervention and months of plaster.
When undetected for years it leads to deformity and eventually to early onset of crippling osteoarthritis of the hip.
X-rays are of no value until twelve weeks after birth and simple clinical examination misses many cases. Management of such late presentation of the condition will drain the resources of any community and Bosnia has much more important surgical matters to deal with. In August 2001 An agreement was signed between the Bosnian Ministry of Health, each of the Sarajevo Hospitals, IDEALS and the Leonard Cheshire Centre to undertake a research project of clinical and ultrasound assessment of infants in The University Clinical Centre and the State Hospital Sarajevo. The main purpose of the survey was to assess those children with a family or obstetric history that indicated the possibility of DDH and initiate early treatment for them when required.
Many -- at least 40 -- who would have not been assessed at all were discovered to need treatment for this condition with simple nonsurgical methods. THIS IS AN EXAMPLE OF A NORMAL ULTRASOUND THAT REQUIRES HIGH LEVEL OF ABILITY TO INTERPRET.
As can be seen from the diagram even a normal ultrasound can appear quite complex and it is certainly so to inexperienced doctors who are required to make precise decisions on whether or not to treat infants. My first attempts at lecturing in a foreign language to a group of doctors of various specialities proved to be a fraught experience. The diagrams are being adapted to permit measurements of angles and assessment of the position of internal hip structures in the original recordings when used as transparent templates against the ultrasound pictures.
These diagrams are not used elsewhere as far as we know and after designing them it was obvious that they could be used in the clinics for easy reference.
They have proved to be a very effective way of not only teaching ultrasonography but also have ensured that there is a set of reference diagrams in the clinic.
The method has proved so effective that we have now been invited to submit a paper on the matter to the British Journal of Hospital Medicine. In addition the diagrams will form an important part of a book that we are publishing on the subject of ultrasound assessment of the infant’s hip. The development of laparoscopic or minimally invasive abdominal surgery has gone apace and was progressing during the Bosnian war. This demonstrates the small wounds that are required in such surgery and the magnified appearance of the internal anatomy that allows precise dissection of the gall bladder form the under surface of the liver. Quite obviously training is required in recognised establishments to allow surgeons to develop the high level of skills required. It is interesting to note that the only complication that, year by year, remained at (nearly) a constant % level was wound infection. This is a very pertinent illustration of how on the cessation of hostilities the effects of the war will continue in subtle ways.
In summary this project has been an excellent one for delivering a high level of care to Bosnian patients. We are now engaged in developing a similar training project for the North West Frontier City of Peshawar and in addition for the purchase of equipment. It is now well recorded that within days of the beginning of the siege of Sarajevo there were so many casualties that medical supplies were almost completely depleted. A very high percentage of individuals with non-fatal war wounds suffered from injuries to the limbs and there are, inevitably, complex fractures of the long bones.
AN EXAMPLE OF SEVERE SOFT TISSUE INJURY WITH MASSIVE FRACTURES BEYOND ANY HOPE OF TREATMENT. In War the civilian approach to treating trauma must be modified to take account of the large numbers of casualties and the more extensive wounds that are seen.
A SEVERE INJURY TO THE PELVIS AND THE UPPER THIGH CAUSED BY AN ANT-AIRCRAFT SHELL DIRECTED AT SARAJEVO POPULATION. Nearly 4,000 patients were treated with the apparatus and it can be safely described as a major life and limb saving device. THE X-RAYS SHOW TWO EXAMPLES OF THE COMPLEX FRACTURES THAT ARE CAUSED BY HIGH ENERGY BULLET WOUNDS SUCH AS BULLETS OR SHELL FRAGMENTS. At the end of the war the use of the device was independently reviewed by Dr Sukrjia Djozi? IDEALS organised and paid for research to be undertaken under the supervision of Professor Alan Amis in the biomechanical laboratory at Imperial College, London. The results were quite remarkable in that the cyclic loading of the device showed that it was resistant to deformity of the fracture up to weight-bearing loads of 300kg.
The experimental work will now continue in comparing Sarafix with other devices that are used in wartime situations.
There can be no doubt that it is a simple apparatus and this is what is needed in adverse circumstances.
The hope for the future is that Sarafix will be seen as one of the major choices for the early fixation of complex fractures in a war situation and could become part of the shelf equipment in Europe for multiple patient (disaster) emergencies. The device could be easily used throughout the world for all types of fractures at a cost that is massively less than the complex devices that are at present available. There is a need for industrial development in Bosnia and based on the clinical and experimental results it is hoped to attract funding to establish a factory to manufacture this and other orthopaedic equipment in Sarajevo.
We are now extending the research work to assess the shearing forces from rotation that are required to disrupt the device with various types of fractures. Despite the best surgery that could be offered many patients suffer from chronic infection following war wounds. SEVERE CHRONIC INFECTION OF BONE AND SOFT TISSUES OF THE LOWER LEG AFTER SHELL FRAGMENT INJURY. There is no doubt that the stabilisation of long bone fractures using the Sarafix method prevented many more from suffering complications including infection but the very nature of high energy missile wounds is such that debris is sucked into the tissues and despite careful and early removal of infected particles some must remain. As the diagrams show the initial results of those undergoing radical surgical care (TREATED in the diagram) proved to be very successful when compared with those who underwent the standard treatment (CONTROL) but unfortunately after three years there was a gradual rise in the reappearance of long-term infection and therefore we must never consider that this is a war disease that is completely eliminated in any individual. This work undoubtedly demonstrated the difference between the requirements for treatment of the two different types of injuries and it was suggested that there is a real need in these turbulent times for British and European surgeons to be trained in war injuries rather than acquiring the knowledge in the acute adverse circumstances ---see (1) in this section. This study revealed considerable persistent symptoms both of a psychological and of a physical nature.
The Medical school was effectively on the front line during the war and the damage was massive.
Although of a high standard and part of the archive of the department they were insufficient and so it was suggested that a computer programme should be purchased by IDEALS. The Leonard Cheshire Centre has been deeply involved in the Azerbaijan refugee problem since the mid 1990’s.
The donation of money for the continuation of the fast track surgical programme as well as the refurbishment and transport of donated infant incubators was obviously very useful.
It was as a result of becoming involved on the periphery of this work that IDEALS was informed of the need to transfer a child from Azerbaijan to England for plastic surgery. This child had suffered severe facial burns as a result of the explosion of a cooking stove and although he had undergone numerous operations in Russia and in Azerbaijan he was still unable to close his eyes due to scar contractures and he had gross mouth deformities. Mr Roberts FRCS, Consultant Plastic Surgeon at Stoke Mandeville Hospital, offered his time and expertise to operate on the boy.
The photographs demonstrate that at the end of this time this boy was able to close his eyes and his mouth.
Research and developing the production of cheap prostheses is essential in many parts of the world. IDEALS, and its predecessor the Bosnian Fund, has accomplished much and identified itself as an educational Charity with research programmes that allows experience gained in war and other adverse situations to be assessed and promulgated. The Charity has never lost its focus to help individuals via its teaching projects and, as can be seen with the extension of work with Sarafix, it may become involved in economic reconstructive activities. We have worked with no administrative costs and derived our income from a very narrow base. It is for others to judge the organisation but those of us working within the Charity believe that we have demonstrated our worth during the past 6 years. Osteomyelitis is an infection of bone and bone marrow caused by hematogenous or contiguous spread of the organism from local infection and or open traumatic fracture. Several immunologic proposals have been made which contribute to our understanding of biofilms and the role that they play in device-related infections. This is seen commonly in children (boys more often than girls) involving metaphysis or epiphysis of long bones most often in the lower extremity. Clinical features include chills, fever, malaise, pain and local swelling of the affected limb. Vertebral osteomyelitis is usually of hematogenous origin rather than retrograde spread via Batsons’s venous plexus.
Contiguous osteomyelitis occurs when the microorganisms are introduced into bone by trauma, nosocomial contamination following surgical procedureA  and extension from adjacent soft tissue infection.
This is a special category seen predominantly in patients with diabetes and peripheral vascular disease and is localized almost exclusively to lower extremities. Posttraumatic osteomyelitis results from pathogenic organisms that proliferate in traumatized tissue. Overall, the incidence of infection in Grade I open fractures is nearly zero, that of grade II open fractures is below 5% and depending on the degree of contamination, in Grade III fractures, the infection rate is between 5-40%.
Chronic sclerosing osteomyelitis primarily involves the diaphyseal bones of the adolescents. The incidence ofA tuberculosis osteomyelitisA varies based on the geographic region and patient risk factors for the disease.
Based upon a certain clinical setting, specific organisms as well as bone sites may be involved (Table 3). Historically, osteomyelitis was classified as either acute or chronic depending on the duration of symptoms.
A history of infection or inter-current illness as well as remote surgery or trauma should raise the clinical suspicion for osteomyelitis. Routine blood cultures are of little help unless the patients have manifestations of systemic disease, such as in hematogenous osteomyelitis (Cierny and Mader Type I).
Radionuclide Scintigraphy is a very useful diagnostic tool and can be performed with various algorithms.
Indium-111 or 99mTC-HMPAO (Ceretec) labeled leukocyte scan is useful as a confirmatory test following a positive Tc-RBC bone scan.
Magnetic resonance imaging continues to play an important role in the evaluation of musculoskeletal infections. Computed tomography has assumed a lesser role in the evaluation of osteomyelitis with the widespread use of MRI. TheA use of fluorine-18 labeled 2-fluoro-2-deoxy- d-glucose positron emission tomography FDG (PET) scanning enables non-invasive detection and demonstration of the extent of chronic osteomyelitis with 97% accuracy. Single Photon Emission Computed Tomography (SPECT) provides a qualitative and quantitative look at the volume distribution of biologically significant radiotracers after injection into the human body. Molecular Diagnostics are being developed for diagnosis in osteomyelitis because some infections remain without an identified pathogen, when using standard techniques. The management of osteomyelitis relies on a multidisciplinary approach, combining debridement, soft tissue coverage, and antimicrobial therapy to give the patient the best chance of cure (Table 5).
If the medullary infection is too proximal (or distal) for a tight reamer fit, a trough must be created to debride the canal directly (saucerization). Often, infection present with a recent reconstruction with the presence of metallic implants and other inert biologic tissue (compromised bone or bone graft). As bacteria become more resistant antibiotic therapy can be challenging, therefore an adequate attempt at identifying a microbiologic pathogen is critical. The duration of antibiotic therapy for osteomyelitis varies as some researchers have recommended as few as two weeks of therapy and others suggested long-term therapy and there is no general consensus. In certain selective settings when radical surgical debridement cannot be performed (Class C hosts), if the hardware has to be left in place to maintain stability such as an acute infection or if the patient refuses surgical treatment eradication of the infection is unlikely. Muscles attached to and surrounding the jaw joint control the position and movement of the jaw.
Patients may complain that it is difficult to find a  comfortable bite or that the way their teeth fit together has changed.  Chewing on only one side of the jaw can lead to or be a result of TMJ  problems.
This continuous pounding on the temporomandibular joint can change the alignment of the teeth.
This trauma can fracture the jawbone, cause dislocation of the TMJ, or cause damage to the cartilage disc of the joint. It is very common for people under stress to release this nervous energy by either consciously or unconsciously grinding  and clenching their teeth.
About 80% of patients with a TMJ disorder complain of headache and about 40% report facial pain, and ear pain. About one half of patients with a TMJ disorder notice ear pain and do not have any signs of ear infection.
Grinding, crunching, clicking, or popping sounds (medical term = crepitus) are common for patients with a TMJ disorder. If your symptoms persist, your doctor may recommend medications or a night guard to help keep you from grinding your teeth at night. Dentist or doctor will recommend over the counter medications (like Aleve or Motrin), or prescription medications such as Dolobid are a first option to relieve pain. Antidepressants prescribed to be taken at bedtime have been successful in relieving TMJ pain in some patients.
These types of drugs are sometimes used for a few days or weeks to help relieve pain caused by TMJ disorders. Injecting botulinum toxin (example Botox) into the jaw muscles may give relief to pain associated with TMJ disorders.
For patients who grind their teeth patients may gain from wearing a  firm custom made appliance. For patients whose main symptom is from stress or anxiety they may benefit from a visit to a psychotherapist. The success of treatment depends on how severe the symptoms are and how well you comply with treatment.
Marielaina Perrone's advanced training and years of experience translate into greater confidence and convenience for your entire family. The stomach lining contains special cells that produce acids and enzymes and this breaks down the ingested food, churns it and grinds it and passes it down to the small intestine. Sometimes the inflammation could be more severe and wear away the lining – this is called erosive gastritis and leads to bleeding and ulcers. These drugs when taken for short spells cause no problems but when taken for long periods can lead to ulcers. However in certain individuals the body mistakenly attacks its own proteins as foreign and damages it.
A stool test could be used to check for the presence of occult blood in the stools and indicates presence of bleeding. If any suspicious area or bleeding point is seen, a biopsy specimen could be taken through the scope and examined. The more serious disease, diverticulitis, may involve anything from a small abscess in one or more of the pouches to a massive infection or perforation of the bowel. The acute form of diverticulitis can manifest itself with one or more severe attacks of infection and inflammation. If these go through the intestinal wall, you may develop peritonitis, a potentially fatal infection that requires immediate treatment. This most frequently occurs between the large intestine and the bladder, and it can lead to an infection of the neighboring kidneys.
The first conversations on this subject were useful for raising morale but eventually hope was converted to real plans for post war reconstruction.

The purchase of the ultrasound machine was proof that if such work is to be successful, then the generosity of others counts at least as much, and perhaps more, than orthodox management! A chance meeting with a complete stranger, Simon Oliver, while I was en route to Sarajevo via Zurich, ensured the creation of IDEALS.
In Sierra Leone, for example, after years IDEALS Review 3 of a civil war there were large numbers of amputees with no chance of affording expensive imported prostheses.
It opens up the possibility of extensive, long term, activity in the area by helping to provide education in immediate trauma care and providing the equipment required for improved clinical activity.
The great theme is education because this is a major requirement in redevelopment of health services following any form of prolonged assault on a society.
It is not only a list of achievements but of lessons learned in using our scarce resources. The war that politicians and militarists hadsought was over but the only beneficiaries were those who always profit fromsuch events.
In a short time the spotlight was redirected, the world’s interest waned and from a media perspective the country darkened like a closed theatre.
This is true in any profession and it is not surprising that the years of isolation from the mainstream of modern medicine reduced the clinical and technical confidence of Bosnian medical staff. The total sum spent on such activities to date is in excess of £5000 via Charity money and IDEALS linked personal donations.
The latter activity was very important because it helped to develop the confidence in themselves and also to show the Bosnians how much their war time work was appreciated. A list of the research and educational activities demonstrates their wide clinical range and the Charity’s involvement.
The Chairman for the group presentation was one of our Trustees Dr E McCoy while the social programme included staying as guests in Mr and Mrs Simon Oliver’s home in Wiltshire and dinner as a guest of another Trustee Mr Bob Marshall Andrews MP at the House of Commons on the evening that the end of the Kosova war was announced. Papers were delivered in a plenary session along with JPBeavis and Cara Macnab from LCC at. Awareness of the existence of the problem is the most important feature in any community and the best way to ensure this is to develop a system of easy referral.
At the time of preparing this document the final figures for the first three years are being developed but the following statements can be confidently made.
The ultrasound diagrams could only be explained with confidence via pictorial aids hence diagrams that related the ultrasounds to the real hip structure were designed. As can be seen the diagrams represent a simple method of describing the abnormalities within the infant’s hip and relating these to the ultrasound appearances. This will be written in collaboration with the Orthopaedic Department of University College Hospital. As a result of our experience in Bosnia the LCC Advisor, Dr Judith Darmady, has asked us to assist in training for ultrasound surveillance of DDH in Romania. LAPAROSCOPIC SURGERY Key words and expressions: Minimally invasive, gallbladder, appendix, hiatus hernia, Royal College of Surgeons of England, cholecystectomy, appendicectomy. It was therefore not surprising that we should be invited by the General Surgical Department at the State Hospital Sarajevo to assist them with the development of this speciality. The diseased organ is delivered onto the surface of the abdomen and immediately enclosed in a sterile container to prevent contamination of the wound. This problem always occurred following removal of a gallbladder, an organ, which is usually infected after obstruction with gallstones. It illustrates the need for a charity such as IDEALS to remain involved in a focused manner long after hostilities have ended.
FRACTURE FIXATION Key words and expressions: Sarafix, external fixation, severe soft tissue injury, infection.
These fractures are associated with gross soft tissue injury and must be stabilised in order to preserve the limb.
EARLY ADEQUATE FRACTURE FIXATION ALLOWS THE MANAGEMENTOF SOFT TISSUE INJURES AND PRESERVATIONOF THE LIMBS. Despite the extremely adverse conditions of war there is no excuse for accepting lower surgical standards although the lack of equipment, drugs and malnutrition of the patients will inevitably lead to a higher level of complications than would be seen in ordinary civilian practice. Clean closed limb injuries in civilian work will allow the insertion of plates or long nails but these devices will inevitably become severely infected and so external fixation must be used. TO STABILISE SUCH FRACTURES WITH PLASTER WOULD BE IMPOSSIBLE AND ALLOW TREATMETNOF THE SEVERE SOFT TISSUE DAMAGE AT THE SAME TIME. This means that an individual and the pull out strengths of the pins (the force required to actually pull the pins out of the bone) were nearly 500kg. This illustrates the way in which pure research based on war experience can be used to try and develop economic benefits for the battered society. For many of these patients repeated surgery was unsuccessful and they suffered the complications arising from chronic infection and open suppurating wounds. JPB (using the resources of IDEALS) became involved in the assessment of patients with chronic infected war wounds. SIX YEARS AFTER THE WOUND CLOSED IT OPENED AGAIN AND INFECTION REAPPEARED REGULARLY UNTIL AFTER FURTHER SURGERY. The value of IDEALS supporting such research is also obvious because such work will identify best methods of treatment and report experience that may be used in the future.
Combined Study Of A Five-Year Review Of Complex War Injuries Affecting The Tibia In The State Hospital Sarajevo And Civilian Injuries In University College Hospital Over A Similar Period. Perhaps the worst effect was psychological rather than physical but the social implication is well illustrated by the diagram, which revealed that the majority of patients five years after cessation of hostilities had failed to return to reasonable employment. Assistance Of Anatomy Department Of The University Of Sarajevo Medical School With Computer Programme To Redevelop Teaching After The War. Five years after the war the only teaching aids available for anatomy were carefully preserved chalk drawings. The programme is till in use and assists with both teaching and examination of the undergraduates. It was the first major project started when Professor James Ryan assumed Directorship of the Department.
The other characteristic that shines through is that despite his hideous scars he is a child who has charisma. We were contacted by a small organisation that hoped to develop prostheses from local materials that had often been discarded.
Today a biofilm can best be described as a dynamic and heterogeneous community of sessile bacteria which are surrounded by an extra cellular matrix of polymers.
From an evolutionary perspective it appears that these cells serve to function like spores, which are more adept at persisting over time but are also less metabolically active.
Children may present with abrupt fever, irritability, and lethargy along with inability to move the affected extremity and pain or passive movement. It involves lower dorsal and lumbar spine with an occasional involvement of the cervical spine.
Complications of vertebral osteomyelitis include epidural abscess, spinal cord compression, paravertebral and retroperitoneal abscess. Fever and systemic toxicity are often absent unless there is severe limb threatening infection with gangrene and fasciitis. Traumatized tissue also results in compromised blood supply, leading to tissue and bone necrosis, which promotes infection.
Other factors that contribute to the development of osteomyelitis are the presence of hypotension, inadequate debridement of the fracture site, malnutrition, alcoholism, and smoking.
Approximately 60% to 70% of open fractures are contaminated by bacteria, but a much smaller percentage develops infection and the risk of subsequent infection is highly correlated with the degree of soft tissue injury (Table 2). Typical features include intense proliferation of the periosteum leading to bony deposits and progressive sclerosis on the radiographs. Radiographic changes include central destruction surrounded by sclerosis usually in the metaphysis of the long bones. While it can involve any bone due to its hematogenous dissemination, it does have a predilection for affecting the spine (Pott’s disease). Several classification systems have been proposed but the most widely used system is that of Cierny and Mader (Table 4) (Figure 1) , which identifies the extent of infection as well as the condition of the host.
Normal signs of inflammation (rubor, calor, dolor, tumor) may be absent and thus the diagnosis of infection when clinical signs are masked can be difficult. If the infection spreads to the cortex (usually within 3 to 6 weeks), a periosteal reaction may be evident on plain radiographs. Reported sensitivities of bone scintigraphy for the detection of osteomyelitis vary considerably from 32% to 100%. The leukocytes migrate to the region of active infection so that the scan can confirm the presence of an active inflammatory reaction. With use of microcolloid bone marrow scans, more information is available to determine whether there is truly an infection. The best potential for determining infection is to add the white cell scan as well as the marrow scan. The sensitivity and specificity of Magnetic Resonance Imaging (MRI) imaging for osteomyelitis range from 60% to 100% and 50% to 90% respectively. Positron emission tomography is especially accurate in the central skeleton within active bone marrow. The most commonly used method for the diagnosis of orthopaedic infections is the polymerase chain reaction.
The first step involves identifying (staging the host) and optimizing the host (treating the morbidity of the host and optimizing their physiologic condition, such as nutrition, smoking cessation, treatment of diabetes, medical or surgical management of vascular disease).
Antibiotic release is bi-phasic, most occurring during the first hours to days post-implantation and the remaining elution persisting for weeks and sometimes for years.
All non-viable and inert structures should be debrided to remove the infected material and debris without destabilizing the bony structure. Greater than 30% loss of circumferential cortical contact or any segmental resection requires stabilization.
The question arises regarding the need to intervene operatively or the ability to remove implants (Table 6).
Rarely will rapid initiation of antibiotic therapy change the clinical course, unless the patient is showing significant signs of systemic toxicity. The selection is based upon in-vitro susceptibilities of the microorganisms causing the infection and ability to penetrate the bone. Short-term therapy is indicated in otherwise healthy patients with total debridement and healthy host tissue. In such instances, use of chronic suppressive therapy may be in order which typically involves long-term administration of oral antibiotic therapy.
For hematogenous osteomyelitis, major risk factors include, indwelling intravascular catheters, distant focus of infection and I.V.

When the muscles are relaxed and in balance and both jaw joints open and close comfortably, we are able to talk, chew, or yawn without discomfort or pain.
A problem with either one can lead to stiffness, headaches, ear pain, bite problems ( also called a malocclusion), clicking sounds, or locked jaws.
Teeth grinding as a habit can result in muscle spasm and inflammatory reactions, thus causing the initial pain. Pain in the TMJ can also occur following dental treatment whereby the joint is stretched open for extended periods of time.
50% of those patients will have resolution of their tinnitus after successful treatment of their TMJ disorder. Your dentist will conduct a careful patient history, dental examination, and take necessary x-rays to determine the cause of your symptoms.
This night guard prevents your teeth from coming together in contact, and repositions teeth to decompress the jaw joint.
This would allow the patient to become self aware of stress triggers as well learning relaxation techniques to relieve stress. As always, it is best to maintain regular appointments to see your dentist and let them know if there any TMJ issues developing. You’ll find complete dental expertise, utilizing the latest advancements in dentistry, all here under one roof.
In certain individuals alcohol can cause damage to the stomach lining and stimulate acid production.
However, in all cases reduction of the stomach acid is the main – stay of treatment and dietary adjustment is also advised. This would help you to focus your mind better at work, calm your anxiety and reduce or relieve your daily anxiety and tension be it physical or mental. In chronic diverticulitis, inflammation and infection may subside, but they may never clear up completely.
Fistulas can occur less commonly between the large intestine and either the skin or the vagina. A consistent request was to support paediatric orthopaedic work and in particular the ultrasound assessment and treatment of the infant condition Developmental Dysplasia of the Hip. We were informed that a nearly new demonstration model of an ultrasound machine was available for £9,000 but it was sold during the 24hours we were considering whether or not to bid. Simon subsequently told me that because of the black shirt I was wearing he thought I was a priest. The Leonard Cheshire Centre for Conflict Recovery at University College London had previously contacted me but I did not feel that a lone individual like me could have anything to offer such an auspicious outfit.
Since the end of the Bosnian civil war a response to acute needs around the world has had to be ruled out because of our limited resources. An example of this occurred during a visit to the British Trauma Society meeting in Belfast during March. The visit to Parliament was also high lighted by the presence of Mr Martin Bell MP who was a much respected BBC war Correspondent in Bosnia during the conflict. The subjects included injury-induced osteomyelitis; the spectrum of war injuries and long term physical psychosocial problems derived form the wounds sustained during the siege of Sarajevo. Leonard Cheshire has paid for the airfares and accommodation of JPB to visit Sarajevo while the main function of IDEALS has been to pay for the training in the UK of surgeons involved in the project and also to pay for Professor Graf to visit with his team on two occasions to undertake courses for a wide variety of specialists in the technique of neonatal ultrasound. When supplemented by the use of ultrasound in detection of the condition a significant improvement occurs in the community with many children being detected within the first weeks of birth. IDEALS supported a Romanian doctor to visit the UK in June 2004 to attend a course in Dorset run by Dr Sally Scott and Professor Graff. The examination of the charts reveals progress but also persistence of the effects of continued deprivation. The reason for the infection is that the sterile containers required to separate the gallbladder from the patient’s skin as it was delivered form the abdomen was not available even six years after the end of the war.
The majority of amputations following war injuries are due to severe soft tissue injuries many of which cannot be treated properly because of inadequate fixation of the complex fractures. One of the most remarkable achievements of the Bosnian war was the development of the external fixator Sarafix. Success was obtained with the Sarafix device as seen on the left in which the healed, severe soft tissue injuries can be seen. These results were obtained with a very simple version of the Sarafix device and the more complex arrangements of pins would certainly enhance the strength of this apparatus. It was estimated that as many as 15,000 patients in Bosnia suffered from this often forgotten problem as a result of the war.
This led on to the development of a technique of radically treating these patients and thus lowering the overall incidence. It also emphasise that individuals who become involved in war surgery, as volunteers must have the specialised expertise to deal with these cases rather than trying to import civilian techniques. As a result of this we have continued on with the detailed studies of Sarafix at Imperial College and further research is hoped to begin using biological models for assessing complex fractures and soft tissue injuries in an attempt to understand both the best methods of treatment and the biological basis for success or failure. Once again this demonstrates the long-term effects of war that are often ignored by those who believe that it begins and ends with violent hostilities. Using the programme the whole human body can be dissected from the skin to whatever depth the student elects and each structure can be identified by an associated reference.
Unfortunately since his return to Azerbaijan he has been lost to follow up but nevertheless it was a worthwhile involvement by IDEALS. IDEALS financed a trip to Sierra Leone for the purpose of establishing these methods and we were happy to record that subsequently the research and development of the materials went ahead. The term cure is not used since the bone infection may relapse after many years of successful remission.
These bacteria by definition exhibit an altered phenotype in comparison to their free floating planktonic counterparts. The clinical significance of biofilms in orthopaedic surgery lies in the fact that biofilms form on implanted hardware and cause infections that are difficult to eradicate.
As such, these less metabolically active cells naturally are less susceptible to chemotherapeutic agents designed to limit cell reproduction. Later when specific enzymes are needed, the reserves are dry and hence a clinically symptomatic infection may occur. Non-anastamotic capillary ends of nutrient artery make sharp loops and enter a system of venous sinusoids with low and turbulent blood flow. In approximately 50% of the cases there may be minimal to no fever, vague complaints including pain of the involved extremity over several months. The infection leads to a thrombosis of one of the segmental arteries supplying two adjacent vertebrae and the intervertebral disc resulting in Ischemia, infarction and bone necrosis. Trauma has been reported to delay the inflammatory response to bacteria, to depress cell-mediated immunity, and to impair function of PMNs, including chemotaxis, superoxide production, and microbial killing. With type IIIB open fractures, those in which extensive soft tissue stripping does not allow for adequate coverage over the site, infection can occur in up to 40% of cases.
Clinical presentation includes a subacute onset and often time’s consideration for the disease occurs in patients with negative bacterial cultures with risk factors for tuberculosis. This system is based on four factors: the degree of osseous involvement, the site of involvement, the degree of impairment caused by the disease, and the general condition of the host. Patients can often have a history of infection of another site, such as the lungs, bladder, or skin, especially with a history of trauma.
Laboratory changes suggestive of infection include elevations in the white blood cell (WBC) count, and elevations in the C-reactive protein (CRP) and Erythrocyte Sedimentation Rate (ESR) levels.
Unfortunately, radiologic findings in the initial presentation of acute osteomyelitis are often normal. After intravenous injection, there is rapid distribution of this agent throughout the extra cellular fluid.
Gallium has been used in conjunction with technetium-99 to increase the specificity of the bone scan. The use of a combined red cell and white cell scan increases both the sensitivity and specificity significantly, and now represents the gold standard of radionuclide testing for infection.
There is the possibility of leukocyte accumulation with certain inflammatory conditions that could result in a false positive indium scan.
It is even more important that the radiologist know the clinical history, view the radiographs and interpret the scintigraphs in such context.
It has the spatial resolution necessary to evaluate accurately the extent of the infection in preparation for surgical treatment and localizes any abscess cavities. It is especially useful in delineating the cortical details in chronic osteomyelitis, such as sequestra and foreign bodies. While it is not yet in widespread use, it remains an adjunctive tool if other methods fail. The overall sensitivity of Tc-99m HMPAO leukocyte scan with SPECT to detect bone infection was 92%, with a specificity rate of 85%. Sequences within bacterial 16S ribosomal RNA have served as targets for amplification and detection. If there are obvious signs of infection such as erythema, copious drainage, edema, and fever, acute surgical debridement and irrigation is needed. Therefore, appropriate consultation and attempts to obtain bone cultures should be the first treatment. The therapy is often prolonged requiring outpatient management, administered intravenously for at least the first two weeks following surgery.
Microbiologic diagnosis must be attempted before considering chronic suppressive therapy and the patient must be compliant and be able to tolerate long-term antibiotic therapy. The temporomandibular joint functions to move the jaw, especially in biting and chewing, talking, and yawning.
We can also feel the joint motion if we put a little finger against the inside front part of the ear canal. Changes in the normal stimuli or height of the teeth, misalignment of the teeth, and changes in the chewing muscles may cause temporomandibular joint changes. Teeth grinding and clenching are habits that may be diagnosed in people who complain of pain in the temporomandibular joint or have facial pain that includes the muscles involved in chewing. Massage and heat application following your dental appointment can help relive the discomfort. These symptoms are usually caused by Eustachian-tube dysfunction (structure responsible for the regulation of pressure in the middle ear). Conventional treatment consists of a diet of soft foods along with warm compresses to settle down the tension of the muscles. This can result in a condition called Pernicious anaemia or auto-immune gastritis where the body no longer can absorb the vitamin B12 and this leads to anaemia. The inflammation of diverticulitis can eventually result in a bowel obstruction, which may cause constipation, thin stools, diarrhea, abdominal swelling or bloating, and abdominal pain.
On hearing of our work the manufacturers offered a completely new machine worth £17,000 for the same price. It is now embedded in the history of the Charity that, (before the aircraft had landed in Zurich but after he was aware of my true identity), Simon wrote me a cheque for £5000! In any event there is no need to supplement excellent emergency services provided by the large international organisations such as the Medécin sans Frontiere, the Red Crescent and Red Cross. Dr Raib Salihefendic received a standing ovation after presenting a paper on the use of the fracture fixation device, Sarafix, for complex injuries.

On completion of this course it is hoped that a full training weekend will be imported into Romania similar to the ones carried out in Bosnia. This device was conceived, designed and the first prototype inserted within a period of five days during May 1992. When compared with the standard apparatus the fracture buckled and stability was lost at a much lower weight-bearing load. For IDEALS to be involved in helping to allay this problem was entirely compatible with its founding principles. The research project profile is now being developed in the hope that this could be initiated at University College Hospital.
In this viewpoint, osteomyelitis behaves much like a benign tumor, in that, it rarely kills, but tends to return without complete ablation.
This apparent antibiotic resistance does not appear to be mediated through traditional cellular modes of antibiotic resistance such as efflux pumps, deactivating enzymes, or target protein mutations.
Similarly, as the immune system reacts but is unable to attack sessile bacteria hidden within the auspices of a biofilm, frustrated phagocytosis may occur. In general, the outcome of acute osteomyelitis in children is good if antibiotic therapy is directed at the responsible pathogen within seven to ten days of the onset of illness.
Erythrocyte sedimentation rate is usually elevated and may be used as a prognostic guide during treatment.
Osteomyelitis should be suspected when bone is exposed before or after debridement or probing the ulcer with a stainless steel probe, bone is encountered. Moreover, the bacteria recovered from clinical infections are most likely to be hospital acquired pathogens such asA S.
Furthermore, with complex bone regeneration techniques, an osteo-myo-cutaneous flap can be slowly transported into the defect. The differential diagnosis includes Ewing’s sarcoma and chondroblastoma especially when localized to epiphysis. Risk factors include: HIV, IV drug abuse, alcoholism, homelessness, immunosupression, history of a positiveA PPDA and former residence in an endemic area. Type I is medullary osteomyelitisA  (examples of which include hematogenous osteomyelitis and infections of IM nails).
The most common radiographic sign of bone infection is rarefaction, representing diffuse demineralization secondary to inflammatory hyperemia soft tissue swelling with obliteration of tissue planes, trabecular destruction, lysis and cortical permeation, periosteal reactions and involucrum formation. Within several hours, more than half the dose will accumulate in bone, while the remainder is excreted in the urine.
Several mechanisms have been postulated to explain the increased activity at sites of inflammation. Leukocytes are labeled and then re-injected, where they redistribute in the intravascular space. An infection will tend to suppress marrow activity and thus render the marrow scan cold, while the white cell scan will still be hot. Otherwise, a rather vague and generic reading will be obtained that has little clinical value to the general practitioner.
T1 and T2 weighted imaging is usually sufficient, fat suppression and STIR (Short TI Inversion Recovery) sequences may be added to better image bone marrow and soft tissue abnormalities.
It also is useful in evaluating the adequacy of cortical debridement in the staged treatment of chronic osteomyelitis. The overall accuracy of FDG-PET in evaluating infection involving orthopaedic hardware was 96.2% for hip prosthesis, 81% for knee prosthesis, and 100% in 15 patients with other orthopaedic devices. The Polymerized Chain Reaction has been used to identify very small remnants of bacteria by identifying their nuclear contents. Then, identifying the organism is required to determine appropriate antimicrobial treatment (the tumor analogy of chemotherapy).
Most of the antibiotic cement use in the US has been off label use by the surgeon, and despite very encouraging results from several studies, their approval has been slow. The critical judgment for the clinician occurs when there is potentially infected bone, that may be partially vascularized, and that is critically needed to maintain the structural stability of the bone. If there is satisfactory fixation and stability of the construct, only non-essential elements such as excess bone graft, should be removed. However, there are times when bone cultures will not be possible or cultures will be negative (despite pathologic evidence suggesting osteomyelitis) and therapy will be empiric. These recommendations are typically made for patients requiring reconstruction surgery involving a large volume of graft and of inert materials. A single dose ofA vancomycinA administered before surgery and followed by two or three doses postoperatively should provide adequate peri-operative prophylaxis. For contiguous osteomyelitis, risk factors include trauma, adjacent soft tissue infection, bites and puncture wounds.
If a patient is experiencing TMJ difficulty the simple act of opening and closing your mouth can cause considerable pain. Opening your mouth allows the rounded ends of the lower jaw (condyles) to glide along the joint socket of the temporal bone.
These can include arthritis, trauma to the jaw, or muscle fatigue from clenching or grinding your teeth. Ear specialists are routinely called on to make the definitive diagnosis of a TMJ disorder. It is believed that patients with TMJ syndromes have hyperactivity (muscle spasms) of the muscles responsible for regulating the opening and closing of the Eustachian tube.
If the obstruction persists, abdominal pain and tenderness will increase and you may experience nausea and vomiting.
On certification of a group of doctors in Romania it may be that a research project can be initiated in the country similar to the one that is now well under way in Bosnia.
Furthermore, the management of osteomyelitis involves diagnosis, staging, treatment, and reconstruction, using methods similar to those used in tumor surgery. The extra cellular glycocalyx matrix portion of the biofilm constitutes one potential area of antibiotic resistance.
As bacteria survive for longer periods there is more opportunity for acquiring traditional methods of cellular antimicrobial resistance. Reactive oxidative species can then be released which cause damage to normal intact tissues which are adjacent to the infection-causing biofilm. In the end, open fractures remain one of the most challenging problems to overcome and treat. The fundamental problem in chronic osteomyelitis is devascularization of bone, leaving protected pockets of necrotic material to support bacterial growth in relative seclusion from systemic antibiotic therapy.
One study reported that in cases of eventually proven osteomyelitis, 5% of radiographs were abnormal initially, 33% were abnormal by 1 week, and 90% were abnormal by 4 week.
There is evidence to suggest that the technetium phosphates bind to both the organic and the inorganic matrix. If the white cell scan is hot as is the marrow scan, it is possible that an infection may not be present. Ongoing data are being presented that may find the regular total body bone scan to be of lesser value when compared to the pair if marrow scan and white cell scanning.
It also has the ability to differentiate between infected bone and involved adjacent soft tissue structures. Unfortunately, it cannot easily delineate between nuclear materials from living or dead bacteria, thus increasing the likelihood of false positive studies. Once the extent of disease, the nature of the host and infecting organism are noted, a determination should be made regarding one of several general treatment algorithms. There are also newer types of material available for local delivery of antibiotics which are resorbable and do not require removal .
Placement of an antibiotic delivery depot (either PMMA or resorbable) with a more aggressive antibiotic regimen may curb the infection until healing has taken place. Antibiotics should be tailored based on the cultures and the specific needs of each patient. These inert materials are the potential site for colonization of bacteria from the blood stream or remnants in the tissue bed until complete revascularization takes place. However, a six-month course is typically administered to contain and not to eradicate the infection. Patients with diabetes have multiple risk factors inherent to the disease along with vascular insufficiency. TMJ disorders most commonly occur in women between the ages of 30 and 50, but can occur in teens after braces, and in both men and women at any age.
You can then continue to enjoy their activities which do not provoke symptoms so that your lifestyle is not restricted unnecessarily. Without Simon’s vision and his extraordinary act of kindness there would be no IDEALS. Simon’s initial donation is still working via the equipment purchased for Bosnia and Azerbaijan and through the patients that were operated on in the Caucasus.
The present section will discuss the pathogenesis, diagnosis, and treatment of osteomyelitis. The structure of a biofilm consists of three basic elements: bacteria, extra cellular matrix, and other interstitial metabolic components. In some instances, diffusion from outside of the biofilm inwards to the sessile bacteria may present a barrier which limits the efficacy of a given antibiotic. This combined with the unique properties of biofilm resistance can lead to an infection which is difficult to conquer.
Clinical studies indicate that open fractures that are properly debrided and covered definitively within 10-14 days have a much lower incidence of late osteomyelitis. This collection of necrotic tissue, bone and bacteria is what is termed the sequestrum and the body’s attempt to wall off the offending material with a reactive and inflammatory tissue (either bone or soft-tissue) is termed involucrum. Type III is localized osteomyelitisA  involving the full thickness of the cortex but without the loss of axial stability.
Local findings include swelling and warmth, occasional redness, tenderness to palpation, drainageA , and restricted range of motion of adjacent joints.
One study examined technetium labeled white cell scans (Tc-HMPAO) versus Tc microcolloid marrow scans in total joints.
Generally speaking however, all three test should be order and will take approximately one week to obtain.
It should be used with fine cuts and can be ordered with contrast to help with surgical planning. FDG- PET appears to be a sensitive and specific method for the detection of infectious foci due to metallic implants in patients with trauma. While sinus tract cultures can be helpful, they should not be the sole guide for antibiotic treatment. Recent studies have found that bacterial typing and assays that target other characteristics of bacteria, such as RNA, may help differentiate between viable and necrotic bacterial elements.
The treatment options available include attempted ablation and cure of the offending infection or in selective cases, such as C-hosts, that are not suitable for this line of treatment , some type of suppressive treatment. Reactive new bone surrounding an area of chronic infection is living and usually does not require debridement. If this treatment is undertaken, suppression with antibiotics should continue until such time and when adequate healing has occurred, there should be strong consideration of re-debridement, removal of hardware and an intra-operative decision as to whether more antibiotic depot treatment is required (Figure 5). Due pharmacological complexities of the available antibiotics, their adverse effects and possible complications, a dedicated infectious disease specialist often times facilitate the treatment process.
Selecting the appropriate oral antibiotic and monitoring of antibiotic therapy can minimize bacterial seeding of the reconstruction site. In patients with fractures suppressive antibiotic therapy is maintained until healing occurs followed by removal of the hardware.
The early association between IDEALS and Leonard Cheshire Centre at University College was of great importance and it is a relationship that has benefited hundreds of patients around the world. Likewise specific antibiotics may be bound by the extra cellular portion of the biofilm and hence rendered ineffective. As planktonic bacteria are intermittently released from the biofilm over time, there are multiple opportunities for the development of a secondary infection. The cumulative effects of these factors when preceded by minor trauma in an infant or a child produce a small hematoma, vascular occlusion and bone necrosis. It should be noted that this involucrum can be highly vascular and potentially viable and structural, which should be taken into consideration during surgical debridement. Type IV is diffuse osteomyelitisA  involving the circumference of the cortex and loss of axial stability.
With a history of trauma, clinical risk factors for infection include a history of open fracture, severe soft tissue injury, a history of substance abuse and smoking, inadequate previous treatment, and an immunocompromised state. In a typical study, gallium is injected intravenously and delayed images are acquired (at 48 to 72 hours).
They found that in 77 patients, the white cell scans had a sensitivity of 96% and specificity or 30% by itself. Gadolinium enhancement should be obtained in the postoperative population to better differentiate post surgical artifact from infection-related bone marrow edema patterns. It is most useful when trying to establish the structural integrity or permeation of the infection into the bone. In a prospective study, Mousa found that 88.7% of deep sinus tract isolates were identical to operative specimens in 55 patients with chronic bone infection. Further investigations are required before these techniques can be widely used as they lack sufficient sensitivity and specificity, but their use remains promising. The sequestrum needs to be identified and removed, whereas the involucrum may be preserved.
When treatment is empirical, clinical response should be evaluated after 2 weeks of treatment to determine if therapy is adequate.
Although most of the early reports suggest such an arrangement may improve outcomes, this has yet to be supported by level I evidence-based data. In order to increase the patient compliance antibiotic agents selected must be least toxic, least expensive and require administration once or twice daily.
Smoking cessation and adequate nutrition play an important role in the outcome of osteomyelitis. The Charity was eventually registered in March 2000 with Trustees Mr Simon Oliver, Dr Michael Price, Dr Eamonn McCoy, Mr Bob Marshall Andrews QC MP and I. The polymeric extra cellular portion of the biofilm can also serve to create an altered microenvironment in which certain compounds may be less able to exert specific effects. As the biofilm matures, there is a greater probability that the planktonic bacteria which are released will be better equipped for survival. However, other bacteria should be considered, depending on the environment, specifically,A C. TheA general condition of the patient is based on those factors that affect the response to infection and treatment.
When the colloid scan was added, the sensitivity went down to 93% but the specificity went up to 98%. Gadolinium may better differentiate abscess formation from diffuse inflammatory changes and non-infectious fluid collections.
It is not useful when there is a lot of metal implant present unless special software manipulations are done to minimize the artifact. 18F-FDG-PET used to investigate infection in postoperative spine holds promise to become the standard imaging technique in this difficult patient population, with sensitivity, specificity and accuracy at 100%, 81%, and 86%, respectively, in a recent study. These results were dependent on aspiration of material by syringe from the depths of an active flowing sinus and immediate inoculation on culture media. While a surgically clean bed with extensive resection is desirable, efforts should be made to maintain axial stability when possible.
When the medullary canal is infected, intramedullary reaming is a good method of debridement. As such, with our current understanding of bio film bacterial, it would be unlikely that the wound could be free of bacteria, so there is a higher likelihood of recurrence of infection. Evidence of response would include, but is not limited to, decreased acute phase reactants along with decreased pain, swelling and tenderness. Professor Jim Ryan of The Leonard Cheshire Centre for Conflict Recovery at UCL and Dr John Martin from Belfast soon joined us. These micro colonies are found with interspersed water channels which provide for the flow of various metabolites, chemicals and nutrients. Sessile bacteria within biofilms appear to be phenotypically different from their planktonic counterparts. Class A patients have normal systemic defenses, metabolic capabilities, and vascular supply to the limb. The first phase represents the blood flow phase, the second phase immediately post-injection represents the bone pooling phase, and the third phase is a delayed image made at 3 hours when there is decreased soft tissue activity. Characteristically, active osteomyelitis displays a decreased signal on T1-weighted imagesA  and appears bright on T2-weighted images . The accurate differentiation between synovitis, loosening or infection is often difficult with conventional X-rays, arthrography, or bone scintigraphy.
Thus, retention of a well vascularized but affected involucrum, or a viable segment of bone adjacent to infection may be retained. It is for this reason that the threshold of hardware removal and re-debridement is lower than normal. Radiographic changes will be delayed and are not a reliable means of monitoring response to treatment.
These antibiotics may be substituted for intravenous agents whenever possible provided that the microorganism is susceptible to these agents. Class B patients have a local (trauma, prior surgery, local inflammation) or systemic (immunosuppressed, on corticosteroids, peripheral vascular disease) deficiency. Most results show improved sensitivity (80a€“100%) and specificity (50a€“100%) for the diagnosis of osteomyelitis.
In another study, an indium white cell scan was compared to technetium sulphur colloid scans to differentiate infection from Charcot arthropathies. The process represents the replacement of marrow fat with water from edema, exudate, hyperemia, and ischemia. Results suggest that FDG PET could be a useful tool for differentiating between infected and loose orthopaedic prostheses as well as for detecting only inflammatory tissue such as synovitis. Histological and microbiologic evaluation of percutaneous biopsy samples should be combined in cases of suspected osteomyelitis. At some point, if adequate resection will result in too extensive a reconstruction that is unsuitable for the host status, amputation is the best option and should not be considered a failure. Intramedullary reaming of the canal as a debridement technique has shown favorable results in the treatment of medullary osteomyelitis. Over the past five years the Charity has been faithful to its description and the philosophy of its name.
Class C patients are those in whom the treatment of the disease (the infection) is worse than the infection itself.
The reported sensitivities and specificities for the diagnosis of osteomyelitis range from 22% to 100% and 0% to 100%, respectively. Indium-labeled WBC scans are generally superior to bone scans and gallium scans in the detection of infection. They found that white cell scans were positive in 4 out of 20 cases, of which three were infected.
The MRI signal characteristics that reflect osteomyelitis are intrinsically non-specific: tumors and fractures can also increase the marrow water content. The sensitivity of culture in the diagnosis of osteomyelitis could be improved from 42% to 84% by the addition of histological evaluation.
In one series, 25 patients with posttraumatic osteomyelitis (of whom 22 were treated with intramedullary reaming) 21 of the 22 patients were free of any recurrent infection. In other words, there is greater potential morbidity or mortality from treatment, than from the infection (or non curative treatment such as suppression).
In one study, evaluating the diagnostic utility of indium scans in 39 patients with suspected osteomyelitis, confirmed by bone biopsy, Indium scans were 97% sensitive and 82% specific for osteomyelitis. In patients without prior complications, MRI has been found to be sensitive (but not specific) for osteomyelitis. Ongoing studies may find it to be more efficacious than the sequence of scintigraphy, but until such studies demonstrate cost efficacy, it may be of less value to the clinician. In such a circumstance, identification of the infecting bacteria is required to allow use of a narrow-spectrum antibiotic; otherwise, broad-spectrum antibiotics are needed.
In a more recent study, 40 patients suffering from chronic osteomyelitis were treated with intramedullary reaming. It should be noted however, that bones can heal in the presence of active infection and unlike arthroplasty, where the implant is considered permanent, the fracture setting allows for implant removal once bone healing has taken place.
Pairing the four types of osteomyelitis with the three host classes, Cierny et al proposed a detailed treatment regimen, which defined optimal treatment modalities for each stage. However, in the four positive cases, the marrow scan was positive in two cases which were confirmed to be infected. When a fracture or prior surgery is evident, MRI is less specific in the diagnosis of infection.
The increased incidence of methicillin-resistant staphylococcal species adds greater emphasis to the need for a microbiologic diagnosis. As one would expect, class A hosts fared the best with success rates of 98% were achieved, even in type IV osteomyelitis.
An accompanying bone scan can help to differentiate bone infection from soft tissue infection.
They concluded that white cell scans can be positive in hematopoetically active bones which can occur in the absence of infection and that marrow scans should be used to confirm the diagnosis.
Furthermore, in the presence of metallic implants, the artifact makes it difficult to comment on areas near the implant, which may be of primary interest.
In these situations, the indium scan should be performed before the bone scan to avoid false-positive results (from the remaining technetium uptake).
When no metallic implants exist, an MRI should be used to help stage the infection, to help determine the extent of both bone and soft tissue infection, and to differentiate between non-specific marrow changes and infection. Until recently, a clinician investigating for the site of infectious foci using nuclear medicine had a choice between 67Ga-citrate imaging and 111In-oxine leukocyte imaging, but scientific advances (especially in nuclear medicine) have increased these choices considerably, and continue to increase them.
