ABSTRACT
We present a rare association of cystic fi brosis and retro positivity in a grossly malnutrited child. The child had pulmonary, pancreatic and colonic manifestations with superadded herpes simplex virus interstitial pneumonia and lymphocytic meningitis.
ABSTRACT
Viral meningitis is a common infectious disease of the central nervous system (CNS) that occurs worldwide. The aim of this study was to identify the etiologic agent of lymphomonocytary meningitis in Curitiba, PR, Brazil. During the period of July 2005 to December 2006, 460 cerebrospinal fluid (CSF) samples with lymphomonocytary meningitis were analyzed by PCR methodologies. Fifty nine (12.8 percent) samples were positive. Enteroviruses was present in 49 (83 percent) samples and herpes virus family in 10 (17 percent), of these 6 (10 percent) herpes simplex virus, 1 (2 percent) Epstein Barr virus, 2 (3 percent) human herpes virus type 6 and 1 (2 percent) mixed infection of enterovirus and Epstein Barr virus. As conclusion enterovirus was the most frequent virus, with circulation during summer and was observed with higher frequency between 4 to 17 years of age. PCR methodology is an important method for rapid detection of RNA enterovirus and DNA herpesvirus in CSF.
A meningite viral é uma síndrome infecciosa comum do sistema nervoso central (SNC), que ocorre no mundo inteiro. O objetivo deste estudo foi identificar o agente etiológico de meningite linfomonocitária em Curitiba, PR, Brasil. Durante o período de julho de 2005 a dezembro de 2006, 460 amostras com meningite linfomonocitária foram analisadas por metodologias de PCR. Cinquenta e nove (12,8 por cento) amostras foram positivas. Enterovirus estava presente em 49 (83 por cento) amostras e herpes vírus em 10 (17 por cento), destas 6 (10 por cento) HSV, 1 (2 por cento) EBV, 2 (3 por cento) HHV- 6 e 1 (2 por cento) infecção mista de enterovírus e EBV. Conclui-se que o enterovirus foi o vírus mais frequente, com a circulação durante o verão. Houve maior número de amostras positivas entre 4 a 17 anos. A metodologia de PCR é um importante método para a detecção rápida de RNA de enterovirus e DNA do herpesvirus no LCR.

Meningitis is the main infectious central nervous system (CNS) syndrome. Viruses or bacteria can cause acute meningitis of infectious etiology. The term "Aseptic Meningitis" denotes a clinical syndrome with a predominance of lymphocytes in the cerebrospinal fluid (CSF), with no common bacterial agents identified in the CSF. Viral meningitis is considered the main cause of lymphocyte meningitis. There are other etiologies of an infectious nature. CSF examination is essential to establish the diagnosis and to identify the etiological agent of lymphocytic meningitis. We examined CSF characteristics and the differential diagnosis of the main types of meningitis.
