Disseminated necrotizing leukoencephalopathy (DNL) is characterized by multiple microscopic foci of white matter necrosis. DNL was initially thought to be exclusively associated with immunosuppression conditions but it has been recently described in immunocompetent patients in septic shock. A 90-year-old immunocompetent woman with no previous neurological impairment presented with septic shock ...

INTRODUCTION Isolated cryptococcal pneumonia in the immunocompetent host is a rare infection. Indications for treatment and its duration are currently not defined. CLINICAL PICTURE Three patients presented with cavitating cryptococcal pneumonia. TREATMENT They were treated with oral fluconazole. OUTCOME Improvement was evident clinically, radiologically and serologically. Fluconazole was ...

Objective: Demodex folliculorum and brevis are two species known to settle on the skin of humans. mite infections called demodicosis. Demodicosis, which is usually asymptomatic, cause some diseases as a result an imbalance in immune system mechanisms This study was conducted investigate relationship between spp. infestations clinical signs, such immunodeficiency, rosacea, blepharitis facial itc...

The present study examined the effects of Vitacel raw fiber on great sturgeon (Huso huso) immunocompetent cell population size including lymphocyte and neutrophil populations and lysozyme activity after oral administration of the feed and Vitacel at 1.3% of the feed for 90 days. Generally, a significant increase was seen in the neutrophil count of fish receiving Vitacel as compared to the contr...

A total of 450 stool samples were collected from inpatient and outpatient clinics of Pediatric Department, Minia University Hospital, Minia District, Egypt. Two groups of patients were studied, including 200 immunosuppressed and 250 immunocompetent children. Stool samples were subjected to wet saline and iodine mounts. A concentration technique (formol-ether sedimentation method) was carried ou...

Cryptococcal meningoencephalitis is a leading of morbidity and mortality in immunocompromised individuals worldwide. However, there are few documented cases in immunocompetent patients. We present a rare case of disseminated Cryptococcus with progression to meningoencephalitis in an immunocompetent patient, with a possible atypical presentation. Magnetic resonance imaging of the brain and elect...

Varicella zoster virus (VZV) is a human neurotropic alphaherpesvirus that causes chickenpox (varicella) in children. VZV reactivation may lead to neurological complications, including transverse myelitis. However, transverse myelitis caused by VZV reactivation is rare in immunocompetent patients. Herein, we report a case of transverse myelitis caused by VZV in an immunocompetent older patient, ...

Cryptococcosis is an invasive fungal infection that occurs worldwide. Infections caused by Cryptococcus (C.) neoformans are commonly associated with immunocompromised patients, while those caused by C. gattii predominantly affect immunocompetent hosts. However, the latter has also been increasingly reported in immunocompromised patients such as those with HIV. Cutaneous involvement by C. gattii...

INTRODUCTION Aspergillus spp. infections mainly affect patients who are immunocompromised, and are extremely rare in immunocompetent individuals. CASE PRESENTATION Aspergillus post-operative mediastinitis is considered to be a devastating infection, usually affecting patients undergoing cardiothoracic surgery with specific predisposing factors. We describe the case of an immunocompetent 68-ye...

Pigs may represent a source of Cryptosporidium sp. infection to humans. The objective of this study was to identify the Cryptosporidium species present in pigs from the State of Rio de Janeiro, Brazil, and verify what risks pigs represent in the transmission of human cryptosporidiosis, because there is no such information to date in Brazil. Ninety-one samples of pig feces were collected from 10...
