Ramsay-Hunt syndrome: Report of two cases with identification of the varicella zoster virus genome in cerebrospinal fluid.

Like other alpha-herpesviruses, the varicella-zoster virus (VZV) remains latent in the neural ganglia following the primary varicella infection. The reactivation of the VZV in the dorsal root ganglia results in herpes zoster. Herpes zoster eruption is characterized by localized cutaneous lesions and neuralgic pain mostly in older and immunocompromised persons, especially those living with the human immunodeficiency virus (HIV).

Kocuria rosea is an uncommon pathogen may cause opportunistic infections in immunocompromised patient. We report a HIV patient, who presented bacteremia caused by Kocuria rosea. He was successfully treated with vancomycin and by catheter removal.

Acute meningoencephalomyelitis due to varicella-zoster virus in an AIDS patient: report of a case and review of the literature.

Varicella-zoster virus (VZV) meningoencephalomyelitis is a rare but severe neurological complication of VZV reactivation in immunocompromised patients. We report the case of an HIV-infected individual who developed an acute and severe meningoencephalomyelitis accompanied by a disseminated cutaneous eruption due to VZV. The presence of VZV DNA in cerebrospinal fluid was confirmed by polymerase chain reaction (PCR) technique.

Primary cutaneous B-cell lymphoma successfully treated with highly active antiretroviral therapy alone: a case report and review of the literature.

Cutaneous B-cell lymphoma (CBCL) is an unusual skin neoplasm with a great range of clinical presentations. Here, we report a case of CBCL in an AIDS patient presented as a single and nodular/ulcerative lesion in the perianal area. The patient was started on highly active antiretroviral therapy alone with a good clinical and oncological response.

[Infection due to Strongyloides stercoralis: epidemiological, clinical, diagnosis findings and outcome in 30 patients].

Background: Strongyloides stercoralis is a nematode parasite, which is endemic in tropical and subtropical regions. Infection usually remains asymptomatic, but in immunocompromised hosts severe and life-threatening manifestations such as hyperinfection syndrome and disseminated disease might occur.

Methods: We retrospectively analyzed the epidemiological and clinical characteristics, including HIV co-infection, microbiological findings, and outcome in 30 patients with strongyloidiasis, who attended in the Infectious Diseases F.
