RESUMO
Batillaria minima is a common snail in the coastal estuaries of Puerto Rico. This snail is host to a variety of trematodes, the most common being Cercaria caribbea XXXI, a microphallid species that uses crabs as second intermediate hosts. The prevalence of infection was higher (7.1%) near mangroves than on mudflats away from mangroves (1.4%). Similarly, there was a significant positive association between the proportion of a site covered with mangroves and the prevalence of the microphallid. The association between mangroves and higher trematode prevalence is most likely because birds use mangroves as perch sites and this results in local transmission to snails.

A total of 82 strains of presumptive Aeromonas spp. were identified biochemically and genetically (16S rDNA-RFLP). The strains were isolated from 250 samples of frozen fish (Tilapia, Oreochromis niloticus niloticus) purchased in local markets in Mexico City. In the present study, we detected the presence of several genes encoding for putative virulence factors and phenotypic activities that may play an important role in bacterial infection. In addition, we studied the antimicrobial patterns of those strains. Molecular identification demonstrated that the prevalent species in frozen fish were Aeromonas salmonicida (67.5%) and Aeromonas bestiarum (20.9%), accounting for 88.3% of the isolates, while the other strains belonged to the species Aeromonas veronii (5.2%), Aeromonas encheleia (3.9%) and Aeromonas hydrophila (2.6%). Detection by polymerase chain reaction (PCR) of genes encoding putative virulence factors common in Aeromonas, such as aerolysin/hemolysin, lipases including the glycerophospholipid-cholesterol acyltransferase (GCAT), serine protease and DNases, revealed that they were all common in these strains. Our results showed that first generation quinolones and second and third generation cephalosporins were the drugs with the best antimicrobial effect against Aeromonas spp. In Mexico, there have been few studies on Aeromonas and its putative virulence factors. The present work therefore highlights an important incidence of Aeromonas spp., with virulence potential and antimicrobial resistance, isolated from frozen fish intended for human consumption in Mexico City.

A case of Kartagener's syndrome (situs inversus, sinusitis and bronchiectasis) is reported at the "Comandante Manuel Fajardo" Teaching Clinico-surgical Hospital, Havana City, in a patient aged 33 years, who presents the three elements of Kartagener's triad. The case was investigated in the Department of Medicine and Department of Radiology. The literature on this uncommon syndrome was reviewed and it was found that there are an open prevalence of this entity in children younger than 15 years, as well as severe respiratory complications in affected patients. Emphasis is made on the importance of early diagnosis and adequate treatment of affections of high respiratory passages, which allows an orientation to avoid future bronchiectasis and sinusopathies. Genetic aspects, as well as incidence of suffering variants, are mentioned. Emphasis is made on specific nursing procedures of this syndrome.

Presentamos una paciente de 31 anos de edad portadora de una enfermedad mista del tejido conectivo (EMTC). Como hallazgo significativo por su baja frecuencia en esta nosologia,presentaba hipoetesia trigeminal e hipertension pulmonar. El tratamiento con prednisona produjo mejoria de algunos sintomas y signos:artralgias,debilidad muscular, derrame pericardico y ascitis, asi como parcialmente,de las pruebas funcionales respiratorias, sin modificar la evolucion de las manifestaciones cutaneas, neurologicas y esofagicas
