Varicella Zoster Virus Infection (varicella + zoster_virus_infection)
Selected AbstractsHerpetic Folliculitis is Usually a Consequence of Varicella Zoster Virus InfectionJOURNAL OF CUTANEOUS PATHOLOGY, Issue 1 2005J Blair Skin biopsies of 8 patients diagnosed with herpetic folliculitis by light microscopy were retrieved from the files of the UCSF Dermatopathology Service. Clinical and microscopical features were reviewed and tabulated, and PCR analysis was employed to seek DNA sequences specific for herpes simplex virus (HSV) and varicella zoster virus (VZV). The study group included 4 women and 4 men, ages 15 to 54. Five patients (62%) were immunosuppressed, with underlying conditions including HIV infection, leukemia, rheumatoid arthritis, and lupus erythematosus with polyarteritis nodosa. Microscopically, herpetic cytopathic changes involved the isthmus in 7/8 cases (87%), and involved the sebaceous apparatus in 4/8 cases (50%). Herpetic viropathic changes were not found within eccrine epithelium. A moderate to dense perifollicular infiltrate, comprised mostly of lymphocytes, was evident in 7/8 cases (87%). After PCR expansion of genetic material extracted from the original paraffin blocks, VZV-specific DNA sequences were detected in 8/8 cases. We conclude that herpetic folliculitis is a consequence of VZV infection. Because follicular herpetic infection is often accompanied by a dense perifollicular lymphoid infiltrate, the microscopical presentation can simulate inflammatory skin diseases such as lupus erythematosus. Level sections may be required for a specific diagnosis to be made.

L. Chee Varicella zoster virus (VZV) infection involving the posterior segment of the eye after fludarabine treatment has not previously been described. Two patients, who had completed fludarabine treatment 3 and 18 months previously, presented with visual loss that had been preceded by a recent history of cutaneous zoster. The use of the polymerase chain reaction (PCR) for VZV DNA from ocular specimens allowed rapid confirmation of clinical diagnosis and treatment with a good outcome in one patient. With the increasing use of fludarabine and other purine analogues, an awareness of such complications is important because of their potentially sight-threatening consequences.

Purpose:, To report central nervous system involvement after varicella zoster virus infection. Methods:, We evaluated the frequency and type of neurological complications in patients initially presenting with ophthalmic herpes zoster at an ophthalmological department in a Danish university hospital, over a 7-year period. Results:, Of the 110 immunocompetent patients who presented with initial ophthalmic zoster, six (5.5%) suffered from neurological complications other than post-herpetic neuralgia. Four experienced isolated cranial motor nerve palsies, one patient had meningitis with a favourable outcome and one patient had severe encephalitis with a poor clinical outcome. Conclusions:, Central nervous system involvement after varicella zoster virus infection is an uncommon, but potentially life-threatening, complication. Early recognition of neurological complications prompts acute, appropriate antiviral treatment. [source] | ||||||||||
