Facial Cellulitis refers to a particular skin infection that reflects swelling or inflammation, redness, pain and warmth. Herpes zoster (or simply zoster), commonly known as shingles and also known as zona, is a viral disease characterized by a painful skin rash with blisters in a limited area on one side of the body (left or right), often in a stripe. Reactivation of varicella-zoster virus (VZV) that has remained dormant within dorsal root ganglia, often for decades after the patient’s initial exposure to the virus in the form of varicella (chickenpox), results in herpes zoster (shingles). A person with shingles can pass the varicella-zoster virus to anyone who isn’t immune to chickenpox. The signs and symptoms of shingles usually affect only a small section of one side of your body.
Most commonly, the shingles rash develops as a stripe of blisters that wraps around either the left or right side of your torso. The aims of treatment are to limit the severity and duration of pain, shorten the duration of a shingles episode, and reduce complications.
Herpes zoster, or shingles, is characterized by unilateral radicular pain and a vesicular rash that is generally limited to a single dermatome. A 65-year-old black Hispanic man whose HIV infection had been diagnosed 1 year ago but had never been treated, presented to the clinic with rash and moderate pain in the right side of his chest of several days’ duration.

Figure 1Figure 1 - Vesicular Rash in a Dermatomal DistributionThis patient developed characteristic herpes zoster as shown by the clusters of vesicles and surrounding erythema, all in a dermatomal pattern. Which of the following statements is TRUE regarding varicella zoster virus (VZV) infection in HIV-infected patients?
A positive Tzanck stain is diagnostic for VZV infection and it rules out other causes of vesicular skin lesions, such as herpes simplex virus infection.IncorrectThe finding of multinucleated giant cells on Tzanck (Giemsa) staining is neither sensitive nor specific for diagnosing viral vesicular lesions. The preferred therapy for dermatomal herpes zoster in HIV-infected patients consists of acyclovir (Zovirax), valacyclovir (Valtrex), or famciclovir (Famvir).CorrectThe medications acyclovir, valacyclovir, and famciclovir are all considered acceptable options for the treatment of dermatomal herpes zoster in HIV-infected patients. The preferred therapy for dermatomal herpes zoster in HIV-infected patients consists of oral valganciclovir (Valcyte).IncorrectIn HIV-infected patients, therapy for localized herpes zoster consists of oral therapy with acyclovir (Zovirax), famciclovir (Famvir), or valacyclovir (Valtrex). The incidence of herpes zoster in HIV-infected individuals is the same as age-matched HIV-negative persons.IncorrectThe incidence of zoster among HIV-infected adults is more than 10-fold greater than age-matched immunocompetent persons.

Primary varicella infection (chicken pox) occurs infrequently in HIV-infected adults, as more than 90% of adults in the United States possess antibodies to the virus as a result of childhood varicella infection.[1] Given the widespread prevalence of varicella-zoster virus (VZV) infection in adults, most HIV-infected adults are at risk of developing VZV reactivation and herpes zoster.
As with all human herpesviruses, primary infection with VZV is followed by a period of viral latency, or "hibernation." Latent VZV resides in dorsal spinal ganglia, until a cycle of "lytic" or active viral replication is initiated.
Primary varicella infection ("chickenpox") in HIV-infected patients manifests as a generalized outbreak of vesicular lesions that follow a 1 to 2 day prodrome of malaise and fever (Figure 1) and (Figure 2). New skin lesions typically continue to emerge for 3 to 4 days.
Significant scarring may result from cutaneous herpes zoster and this is most problematic with facial involvement. Persons infected with HIV have a greater risk of developing disseminated infection, including development of widespread cutaneous lesions, ocular infection, visceral organ inflammation, and central nervous system disease.[8,9] With dissemination and ocular involvement, patients may develop acute retinal necrosis or progressive outer retinal necrosis ("PORN"), conditions that represent necrotizing retinopathy. In most circumstances, the diagnosis of cutaneous herpes zoster is made on clinical grounds.
In general, HIV-infected patients with uncomplicated varicella infection can be treated with oral antiviral therapy.
Initiation of VZV-specific antiviral therapy for localized zoster may prevent serious morbidity among HIV-infected patients. Although cases of acyclovir-resistant VZV have been reported in HIV-infected persons, they appear to occur infrequently and typically involve patients with very advanced immunosuppression.
Management of patients with progressive outer retinal necrosis (PORN) or acute retinal necrosis (ARN) requires a multi-pronged approach (Figure 9), including intravenous and intravitreal therapy, and should include an ophthalmologist who has experience managing complicated eye-related infections.[4] The duration of therapy, frequency of intravitreal injections, and number of intravitreal injections depend on the patient's clinical course and should be determined by an ophthalmology expert. In the rare instance when an HIV-infected person who is non-immune to VZV has significant exposure to a patient with active varicella or zoster, varicella zoster immune globulin (VZIG) should be administered as soon possible after the exposure, but within 10 days.[15] In December, 2012 the United States Food and Drug Administration approved the VZIG product (VariZIG), made by Cangene Corporation in Canada.

ART drugs, leading to subtherapeutic serum levels and the development of antiretroviral drug resistance.
OIs that occur after patients have been started on ART can be categorized into three groups. Physiologic changes during pregnancy can complicate the recognition of OIs and complicate pharmacokinetics. Increased cardiac output by 30%--50% with concomitant increase in glomerular filtration rate and renal clearance.
Increased plasma volume by 45%--50% while red cell mass increases only by 20%--30%, leading to dilutional anemia.
Young children with cryptosporidial diarrhea might infect adults during diapering and cleaning after defecation.
Among persons with profuse diarrheal illness, a single stool specimen is usually adequate for diagnosis.


It can affect people of any age and if left untreated, can result into severe complications by spreading across other tissues of the body, including the blood and lymph nodes. The initial infection with varicella zoster virus (VZV) causes the acute, short-lived illness chickenpox which generally occurs in children and young adults.
Although it is usually a self-limited dermatomal rash with pain, herpes zoster can be far more serious; in addition, acute cases often lead to postherpetic neuralgia (PHN). Shingles in or around an eye (ophthalmic shingles) can cause painful eye infections that may result in vision loss.
Depending on which nerves are affected, shingles can cause an inflammation of the brain (encephalitis), facial paralysis, or hearing or balance problems. It results from reactivation of latent varicella-zoster virus (VZV) within the sensory ganglia.
Use of PCR or direct fluorescent antibody (DFA) testing would be more appropriate and can specifically differentiate VZV from other viruses. The duration of therapy is typically 7 to 10 days, but longer courses should be considered if the lesions are slow to resolve.
Neither intravenous ganciclovir (Valcyte) nor oral valganciclovir (Valcyte) are recommended to treat herpes zoster.

The incidence of zoster among HIV-infected adults is more than 15-fold higher than age-matched VZV-infected immunocompetent persons, with nearly 30 cases per year observed for every 1,000 HIV-infected adults.[2] The diagnosis of herpes zoster should prompt the clinician to consider HIV testing, particularly in persons with known HIV risk factors, those younger than 50 years of age, or those who develop multi-dermatomal herpes zoster. The factors governing the maintenance of latency or the progression to viral replication remain poorly understood, but the increased incidence of zoster among immunocompromised persons suggests that cell-mediated immunity probably plays a critical role.
Patients with herpes zoster often present with dysesthesias of the skin several days prior to the onset of cutaneous lesions. Reactivation of herpes zoster in the trigeminal ganglia may lead to the development of herpes zoster ophthalmicus, a condition that includes a number of inflammatory manifestations in the eye, such as conjunctivitis, episcleritis, keratitis, and iritis. For patients who have an atypical clinical presentation or a questionable diagnosis, confirmatory VZV-specific tests should be performed. In contrast, HIV-infected persons with complicated primary varicella infection, including involvement of visceral organs, retina, or the central nervous system, should receive treatment with intravenous acyclovir and undergo hospitalization for observation (Figure 7). Ideally, consultation should be obtained with a medical provider who has experience and expertise in managing serious VZV infections. The recommended antiviral treatment options (Figure 8) for localized dermatomal zoster in HIV-infected persons consist of valacyclovir (Valtrex), famciclovir (Famvir), or acyclovir (Zovirax).[4] Note these antiviral medications are administered at doses higher than those commonly used for the treatment of uncomplicated herpes simplex virus infections. In general, resistance should be suspected in patients who have lesions that do not improve within 10 days of starting antiviral therapy.

However, IRIS has occurred weeks after ART was started and in sequestered sites such as bone. The tidal volume increase of 30%--40% should be considered if ventilatory assistance is required. Methylprednisolone at 75% of the respective prednisone dose can be used if parenteral administration is necessary. Certain clinicians prefer IV pentamidine because of convincing data regarding its high degree of efficacy. Failure attributed to lack of drug efficacy occurs in approximately 10% of those with mild-to-moderate disease. The absence of IgG antibody makes a diagnosis of toxoplasmosis unlikely but not impossible. Person-to-person transmission is common, especially among sexually active men who have sex with men (MSM). Nationally distributed brands of bottled or canned carbonated soft drinks are safe to drink.
Facial cellulitis is basically caused due to bacteria; the commonest one affected adults are staphylococcus and streptococcus.
Once an episode of chickenpox has resolved, the virus is not eliminated from the body and can go on to cause herpes zoster often many years after the initial infection. Depending on the location of the pain, it can sometimes be mistaken for a symptom of problems affecting the heart, lungs or kidneys.
However, a study on untreated herpes zoster shows that, once the rash has cleared, postherpetic neuralgia is very rare in people under 50 and wears off in time; in older people the pain wore off more slowly, but even in people over 70, 85% were pain free a year after their shingles outbreak. This condition is known as postherpetic neuralgia, and it occurs when damaged nerve fibers send confused and exaggerated messages of pain from your skin to your brain. The incidence and severity of herpes zoster increase with advancing age1; more than half of all persons in whom herpes zoster develops are older than 60 years.
Herpes zoster infection as an immune reconstitution inflammatory syndrome in HIV-seropositive subjects: a review. The DFA uses fluorescent labeled antibodies that detect antigens specific to VZV, and it yields more rapid and accurate results than culture. Replication of VZV in the ganglia leads to inflammation and cell death, followed by transport of the virus down the neuronal axons to the skin, with the migrating virus subsequently causing vesicles to emerge along the path of sensory nerves in a dermatomal distribution. Some patients develop dysesthesias of the skin without developing skin lesions in a condition referred to as "zoster sine herpete." The cutaneous lesions of zoster initially appear as clusters of vesicles surrounded by an erythematous base (Figure 3), with the individual lesions ranging in size from several millimeters to a centimeter. Aseptic meningitis commonly occurs in both immunocompetent and HIV-infected patients, and may be characterized by headache, cerebrospinal fluid (CSF) pleocytosis and the presence of VZV DNA in the CSF. The direct fluorescent antibody (FA) assessment of a cellular rich sample from the base of the lesion offers the most sensitive, specific, and rapid diagnosis for herpes zoster.


In most antiviral studies, therapy was initiated within 3 days of the onset of rash, but one study in immunocompromised patients suggested substantial benefit from administering antiviral drugs even after 72 hours had elapsed.[12] Many experts would consider using intravenous acyclovir for zoster ophthalmicus. One report described 18 HIV-infected patients with advanced immunosuppression and acyclovir-resistant VZV-related skin lesions that failed to heal despite treatment with acyclovir[14]; most of these patients had an excellent respond to treatment with foscarnet (Foscavir). At first, Haemophilus influenzae bacterium (Hib) type B was the most common cause of facial cellulitis in children, after whose vaccine was developed; there was no single form of bacteria that could be linked with this particular skin infection among children.
Herpes zoster is not the same disease as herpes simplex, despite the name similarity; both the varicella zoster virus and herpes simplex virus belong to the same viral subfamily Alphaherpesvirinae. On examination, the patient had an erythematous, maculopapular, vesicular rash in the T8 dermatome distribution of the right side of his chest. Bacterial superinfection of vesicles can also complicate cutaneous herpes zoster (Figure 6).
Encephalitis, presenting as delirium, may either precede or follow the cutaneous manifestations of VZV in the severely immunocompromised patient, and can lead to white matter demyelination, vasculitis, and stroke.[11] Direct spread from the dorsal root ganglion to the spinal cord may result in transverse myelitis and manifest as flaccid paraplegia. For a high yield on cutaneous vesicular lesions, it is critical to unroof the vesicle and vigorously scrape the base of the lesion.

A diagnosis of shingles was made on the basis of the typical presentation, and it was later confirmed by a culture of a sample taken from one of the blisters.

Although herpes zoster can occur anywhere on the body, the skin of the thorax is the most frequently involved region. Use of Tzanck smears is not recommended, mainly because of low sensitivity and very poor specificity.

The vesicles characteristically progress to form crusted lesions (Figure 5) during the subsequent one to three weeks. Culture of these lesions often fail to yield VZV and may take longer than 7 days before final results are available.
Although other infections, such as herpes simplex virus and smallpox, may cause similar appearing vesicular lesions, the characteristic dermatomal distribution of herpes zoster helps to distinguish herpes zoster from these other disorders. Evidence of VZV DNA may be detected in other body fluids, including cerebrospinal fluid, vitreous humor, or bronchoalveolar lavage fluid, but there is little clinical utility in looking for VZV in the serum.

After 2 years, his HIV infection remains well controlled: his viral load is undetectable and his CD4 count is rising, but the pain has persisted and has been difficult to control. Never ignore professional medical advice in seeking treatment because of something you have read on the WebMD Site. A keloid with a linear distribution along the affected dermatome in an HIV-infected person.Typical zoster lesions are clinically recognizable, with pain and vesicles limited to an easily identifiable dermatome. The presentation is subtler when few lesions occur, sparse lesions are covered by hair, vesicles have not yet erupted, or existing lesions are grouped close to the midline so that the dermatomal pattern is less evident. Diagnostic clues include the presence of lesions, sensory symptoms that do not cross the midline, and pain or sensory signs. In HIV-infected patients, the lesions might get worse after the initiation of antiretroviral therapy because of the development of immune reconstitution inflammatory syndrome.3 Systemic antiviral therapy is strongly recommended for all HIV-infected patients and some immunocompetent patients (eg, those older than 50 years or who have moderate to severe pain, moderate to severe rash, or nontruncal involvement).
Acyclovir, licensed in the United States in 1982, has been the antiviral therapy of choice, but famciclovir, another oral antiviral agent, is also effective. Both the incidence and the duration of postherpetic neuralgia are directly correlated with increasing age. Itchy blisters that appear after hiking, gardening, or spending time outdoors could be a reaction to poison ivy, oak, or sumac. The first time someone is exposed to the virus, it causes the widespread, itchy sores known as chickenpox.
If you have shingles symptoms, see your health care provider even if you think you've never had chickenpox. Many childhood cases of chickenpox are mild enough to go unnoticed, but the virus can still linger and reactivate. In most healthy people, the blisters leave no scars, and the pain and itching go away after a few weeks or months. People older than age 60 are 10 times more likely to get shingles than children under age 10.
This pain, due to damaged nerves in and beneath the skin, is known as postherpetic neuralgia. Prompt treatment can make a case of shingles shorter and milder, while cutting in half the risk of developing postherpetic neuralgia.
If the pain is severe or the rash is concentrated near an eye or ear, consult your doctor right away. To speed up the drying out of the blisters, try placing a cool, damp washcloth on the rash (but not when wearing calamine lotion or other creams.) If your doctor gives you the green light, stay active while recovering from shingles. In a large trial, this vaccine cut the risk of developing shingles in half and reduced the risk of postherpetic neuralgia by 67%. The vaccine won't treat a current outbreak of shingles, but it can prevent future attacks if you have already had shingles.
