Caracteristicas epidemiologicas de 105 casos de criptococosis diagnosticados en la república Argentina entre 1981-1990

Se presentan 105 casos de criptococosis diagnosticados en la República Argentina, entre 1981 y 1990. El número anual de casos fue hasta 1987, de 4 a 8, aumentó desde 1988 por influencia del SIDA y llegó a 35 casos en 1990. La criptococosis no asociada al SIDA se mantuvo entre 3 y 7 casos anuales. Globalmente, el grupo etario más afectado fue el de 20-39 años y la distribución por edad fue diferente en las poblaciones con y sin SIDA. La mediana de la edad de las poblaciones total, asociada al SIDA y a otras causas predisponentes fue de 30, 30 y 45 años, respectivamente. El predominio del sexo masculino fue mucho más evidente entre los pacientes HIV+ que en los que no padecían esta última infección. La causa predisponente fue el SIDA en 57 pacientes, otra en 20 y era desconocida en 28 casos. Estimando indirectamente, el porcentaje de pacientes con SIDA que padecieron criptococosis en este período fue 6,19% (57 casos en 920 HIV+). Cryptococcus neoformans variedad neoformans fue aislado de 101 pacientes y la variedad gattii (serotipo B) de los 4 restantes. Los datos obtenidos son similares a los observados en Europa y Estados Unidos.

Surveillance of arbovirus infections in the atlantic forest region, State of São Paulo, Brazil: I. detection of hemagglutination-inhibition antibodies in wild birds between 1978 and 1990

We report data related to arbovirus antibodies detected in wild birds periodically captured from January 1978 to December 1990 in the counties of Salesópolis (Casa Grande Station), Itapetininga and Ribeira Valley, considering the different capture environments. Plasmas were examined using hemagglutination-inhibition (HI) tests. Only monotypic reactions were considered, except for two heterotypic reactions in which a significant difference in titer was observed for a determined virus of the same antigenic group. Among a total of 39,911 birds, 269 birds (0.7%) belonging to 66 species and 22 families were found to have a monotypic reaction for Eastern equine encephalitis (EEE), Venezuelan equine encephalitis (VEE), Western equine encephalitis (WEE), Ilheus (ILH), Rocio (ROC), St. Louis encephalitis (SLE), SP An 71686, or Caraparu (CAR) viruses. Analysis of the data provided information of epidemiologic interest with respect to these agents. Birds with positive serology were distributed among different habitats, with a predominance of unforested habitats. The greatest diversity of positive reactions was observed among species which concentrate in culture fields.

Meningococcal Disease Caused by Neisseria meningitidis Serogroup B Serotype 4 in São Paulo, Brazil, 1990 to 1996

A large epidemic of serogroup B meningococcal disease (MD), has been occurring in greater São Paulo, Brazil, since 1988.21 A Cuban-produced vaccine, based on outer-membrane-protein (OMP) from serogroup B: serotype 4: serosubtype P1.15 (B:4:P1.15) Neisseria meningitidis, was given to about 2.4 million children aged from 3 months to 6 years during 1989 and 1990. The administration of vaccine had little or no measurable effects on this outbreak. In order to detect clonal changes that could explain the continued increase in the incidence of disease after the vaccination, we serotyped isolates recovered between 1990 and 1996 from 834 patients with systemic disease. Strains B:4:P1.15, which was detected in the area as early as 1977, has been the most prevalent phenotype since 1988. These strains are still prevalent in the area and were responsible for about 68% of 834 serogroup B cases in the last 7 years. We analyzed 438 (52%) of these strains by restriction fragment length polymorphism (RFLPs) of rRNA genes (ribotyping). The most frequent pattern obtained was referred to as Rb1 (68%). We concluded that the same clone of B:4:P1.15-Rb1 strains was the most prevalent strain and responsible for the continued increase of incidence of serogroup B MD cases in greater São Paulo during the last 7 years in spite of the vaccination trial.

Amputações de Membros Efectuadas nos Hospitais do Serviço Nacional de Saúde nos Anos de 1990 a 1993

Foi objectivo deste trabalho obter uma panorâmica sobre amputações de membros efectuadas em Portugal nos Hospitais do Serviço Nacional de Saúde num período de quatro anos (1990 a 1993), analisando-se a sua distribuição por etiologias e sexo, idade média, demora média de internamento, nível de amputação e taxa de mortalidade. Os autores destacam ainda os níveis de amputação mais favoráveis para uma reabilitação eficaz.
