Infection in the lower respiratory tract is far more serious than upper respiratory tract infection. It is important to base the antibiotic of choice on the sensitivity test and isolated bacteria because of increasing bacteria resistant to antibiotics and traditional treatments are now becoming less effective. In children, procaine penicillin and amoxicillin are found to have greater effect compared to cotrimoxazole for community-acquired pneumonia.
Increased fluid intake is usually advised by doctors to patients having lower respiratory tract infection. Around 2,350 people get bacterial meningitis and associated septicaemia each year in the UK.Around 50% of meningitis cases in the UK are among under 5s, babies and toddlers.
University students are also at a higher risk of meningitis with 15-19 year olds two and a half times more like to carry a meningitis causing bacteria than adults.What causes meningitis?Meningitis is almost always caused by a bacterial or viral infection that began elsewhere in the body, such as in the ears, sinuses or upper respiratory tract.
Protection against meningitis B and C is part of routine childhood vaccinations, and protection against meningitis ACWY is offered to teenagers and new university students. If the bacteria have also entered the blood, they can release toxins that damage healthy tissue. If the symptoms of viral meningitis are severe enough to warrant admission to hospital, it will be treated in the same way as bacterial meningitis until a diagnosis has been confirmed. Most people with viral meningitis will not require hospital treatment and will recover within 14 days without the need for treatment. If you have fungal meningitis, you will receive anti-fungal drugs to fight the particular type of fungal infection.
Upper respiratory tract infections range from common, benign processes, such as nasopharyngitis, to uncommon, potentially lethal processes, such as epiglottitis.
Upper respiratory tract infections typically occur after insults to host defenses—such as allergic rhinitis, chemical irritation, trauma, and, especially, viral respiratory tract infections— that impair ciliary function and produce increased volumes of thin secretions and mucosal edema that block the narrow channels draining the sinuses and middle ear. Although infections of the paranasal sinuses are common, they are greatly overdiagnosed by patient and physician.
Nosocomial sinusitis occurs as a complication of nasotra-cheal intubation or, less often, the use of nasoenteric feeding tubes.4 Unexplained fever may be the presenting symptom, and computed tomography scanning is often required for diagnosis if the patient cannot localize the pain.
Frontal sinusitis produces pain and tenderness over the lower forehead and purulent drainage from the middle meatus of the nasal turbinates. Acute sinusitis The diagnosis of acute sinusitis can usually be established on clinical grounds.
Because of technical difficulties in obtaining valid cultures, the bacteriology of sinusitis has been incompletely defined.

This leaflet gives some tips on what to do, and what symptoms to look out for which may indicate a more serious illness. Lower respiratory tract infection is always referred to pneumonia but it can also refer to other illnesses like acute bronchitis and lung abscess. Acute bronchitis is an acute viral or bacterial infection of the large airways in people who are healthy without recurrent disease history. It is classified as community-acquired or hospital-acquired depending on where the patient has acquired the infection.
Fungal meningitis is a rare form and usually only affects people with weakened immune systems. Less common causes of meningitis include fungal infection, immune system disorders and medications.Bacterial meningitisThe bacterial form of meningitis is an extremely serious illness that requires immediate medical attention.

Neisseria meningitidis, or “meningococcus”, is common in young adults, and Streptococcus pneumoniae or “pneumococcus” is the most common form in adults. If you are around someone who has bacterial meningitis, seek medical advice to ask if you need to take steps so you don’t become infected. Intravenous antibiotics are used to treat the underlying infection, while life-support equipment and intravenous fluids are used to help support the body as it recovers.
Mechanical defenses tend to prevent penetration by organisms from the nasopharynx and oral cavity into more vulnerable areas.
Barotrauma, which results from a rapid change in atmospheric pressure, can intensify upper respiratory tract problems, particularly in patients with rhinitis, otitis, or sinusitis.
The proximity of upper airway structures to the central nervous system and the presence of abundant vascular channels connecting the two account for some of the most severe complications. Acute sinusitis is characterized by nasal congestion, purulent nasal discharge, fetid breath, facial pain that typically increases when the patient stoops forward, and, often, fever and other systemic symptoms.
Nose blowing propels nasal fluid into the sinuses, potentially introducing viscid fluid and bacteria that can lead to sinusitis.3 Nasal polyps, deviation of the nasal septum, or hypertrophied adenoids may predispose to purulent sinusitis by obstructing sinus drainage.
Frontal sinusitis and maxillary sinusitis are most common in adults; ethmoiditis is most common in children. They are uncommon pathogens in acute infections but are common pathogens in chronic sinusitis and otitis, as well as in abscesses, soft tissue infections, and periodontal infections; aerobic pathogens participate synergistically in most of these processes. Such fungi as As-pergillus, Mucor, and Rhizopus species produce invasive sinusitis in patients with leukemia or poorly controlled diabetes10,11 and, occasionally, in normal hosts.10 In immunocompromised patients, sinusitis may also be caused by Candida, Alternaria, Pseudomonas, Nocardia, Legionella, atypical mycobacteria, and certain parasites.
Several longitudinal studies have been performed to determine the role that the implicated genes are related to innate or adaptive immune response to viral infection. Balentine received his undergraduate degree from McDaniel College in Westminster, Maryland. Nabili received his undergraduate degree from the University of California, San Diego (UCSD), majoring in chemistry and biochemistry.
The first line treatment for this infection is antibiotics but these are not prescribed for viral infections. Haemophilus influenza type b (Hib) was a common form in infants until the Hib vaccine was introduced for infants. In many instances, bacterial meningitis develops when bacteria get into the bloodstream from the sinuses, ears or other part of the upper respiratory tract. These regions are normally teeming with a variety of microbial flora, and many potential pathogens can temporarily colonize these epithelial surfaces without causing true infection [see Table 1]. In addition, the numerous fascial planes of the head and neck provide potential spaces where infection can become sequestered.
In most patients, acute sinusitis responds well to medical therapy; in a few persons, however, chronic sinusitis may result.
Cigarette smoke and overuse of topical decongestants impair ciliary action and alter the mucous blanket, predisposing to sinusitis. Sinus punctures reveal that the most common pathogens in acute sinusitis are Haemophilus influenzae, pneumococci, streptococci, and Moraxella catarrhalisF Staphylococcus aureus has been isolated in nasal cultures from some patients with acute sinusitis, but the organisms are probably contaminants rather than the true causative agents. Most often, when we are told that we have a viral infection, it is because we have an upper respiratory infection that isn't the flu or the common cold.
He attended medical school at the Philadelphia College of Osteopathic Medicine graduating in1983.
There he was involved in research in radiation biology and received the Huisking Scholarship.
It is important to have the right kind of medication based on the bacteria involved to ensure treatment success and to avoid bacterial resistance.
Some use antibiotics as treatment for viral bronchitis but its effects are not that beneficial compared to the side effects it may exhibit such as increased resistance, nausea and vomiting, and cost of treatment. In children with severe pneumonia, oral antibiotics are as effective with injectible once without the need to experience injection pain, high cost and risk for infection. Meningococcus and pneumococcus account for most of the bacterial meningitis cases in the UK.
The bacteria then travel through the bloodstream to the brain.Viral meningitisViral meningitis is more common than the bacterial form and generally, but not always, less serious. Most people, if treated early enough, will make a partial recovery within 10 to 14 days, though it may be several weeks or months before they recover fully.

In addition, local immunologic defenses attempt to deal with organisms that have breached the mechanical barriers; such defenses include abundant lymphoid tissue, secretory IgA antibodies in respiratory secretions, and a rich vasculature that can rapidly deliver phagocytic leukocytes. Furthermore, because the upper airway is narrow, infection in the neck may compromise the patency of the airway itself. Chronic sinusitis is characterized by purulent discharge, usually without fever, that persists for weeks or months.
Contributing factors may include rapid changes in altitude, trauma, in-tranasal foreign bodies or tumors, cocaine abuse, and such systemic processes as cystic fibrosis and Kartagener syndrome (situs inversus, bronchiectasis, and sinusitis). His graduate training included a specialized fellowship in public health where his research focused on environmental health and health-care delivery and management. Amoxicillin is the first line drug for community acquired pneumonia while intravenous azithromycin is the first line drug if there is a risk of death. As a result, the microbiology laboratory faces the challenge of isolating potential pathogens from the normal mouth flora, and the clinician faces the challenge of distinguishing between the carrier state and active infection. Finally, immunosup-pression renders persons vulnerable to unusual pathogens and unusual complications. Factors that predispose to chronic sinusitis include inadequately treated bacterial infections, long-term impairment of mucociliary clearance, obstruction of sinus drainage, and allergies and asthma. Patients with eth-moidal sinusitis complain of retro-orbital pain and may have pain, tenderness, and even erythema over the upper lateral aspect of the nose. Radiologic studies are essential in the diagnosis of severe, refractory, nosocomial, or complicated cases of sinusitis but are not necessary in routine cases.
Joseph's Hospital in Philadelphia and his Emergency Medicine residency at Lincoln Medical and Mental Health Center in the Bronx, where he served as chief resident. Louis University School of Medicine, he completed his Internal Medicine residency and Rheumatology fellowship at the University of California, Irvine. Ticarcillin and gentamicin with clavunalic acid is given intravenously in severe cases of hospital acquired pneumonia. People with viral meningitis are much less likely to have permanent brain damage after the infection resolves.
A respiratory epithelium, composed of ciliated columnar cells, goblet cells, and mucous and serous glands, lines the paranasal sinuses, the middle ear, and the airway below the epiglottis. The anterior ethmoidal cells drain through the middle meatus, whereas the posterior cells drain through the superior meatus. Treatment and management include causative-agent identification, pain relievers for chest pain, oxygen, physiotherapy, bronchodilators, and hydration.
Most will recover completely.Fungal meningitisFungal meningitis is much less common than the other two infectious forms. Isolated sphenoid sinusitis, which occurs in only 3% of patients with sinusitis, is often misdiagnosed. Because these areas are inaccessible for routine culture, it is often necessary to diagnose and treat infections on the basis of clinical findings and statistical probabilities [see Table 1] rather than on the basis of bacteriologic data derived from an individual patient. This disorder has traditionally been considered to cause pain at the occiput or vertex; in fact, frontotemporal, retro-orbital, or facial pain is more common.
An area of the back is injected with an anaesthetic, and a needle is slipped between two bones in the spine to obtain a small sample of spinal fluid. See separate leaflets about other infections of the respiratory tract and related structures, called 'Bronchiolitis', 'Pneumonia', 'Tonsillitis', 'Sore Throat', 'Sinusitis - Acute', and 'Pleurisy'.
Because the disease can progress very rapidly, treatment will begin immediately, even before the results of the tests are known.What is the treatment for meningitis?The bacterial form of meningitis is especially dangerous and must be treated quickly.
Go to the nearest accident and emergency department right away if you suspect you have meningitis. Many viruses are passed on by touch, especially from hands that are contaminated with a virus.
