RESUMEN

Streptococcus suis (S. suis) is a zoonotic pathogen commonly found in Asian countries. Infection with this bacterium typically clinically presents as meningitis and individuals whom handle swine are at increased risk of developing infections. We present a case of a patient with a S. suis meningitis who worked as a butcher. The 48-year-old man was admitted to our department with headaches, fevers, nausea and bilateral hearing loss. According to his medical history, the patient had sustained a cut on his finger while preparing pork meat. A microbiological examination of the cerebrospinal fluid and blood revealed S. suis. The patient was empirically treated with ceftriaxone, vancomycin and dexamethasone. The patient made a complete recovery from the meningitic process and inflammatory markers. However, the hearing and vestibular loss persisted with considerable functional impact upon his daily life. He was elected for a right cochlear implant, 7 weeks after the presentation with a poor outcome. It is important to remember that inner-ear dysfunction can occur frequently in S. suis meningitis surviving patients. Physicians should have a high index of suspicion if risk factors are present and initiate urgent treatment to prevent serious long-term consequences.

RESUMEN

The early stages of the Panulirus echinatus were hatched and reared in the laboratory. Ovigerous females were captured in their habitat and carefully transported to the laboratory. Larvae were transferred in a recirculation water tank at a density of 10 larvae.L(-1). The larvae were fed on Artemia and gonads of mussel Brachydonts sp. Microalgae Dunaliella viridis was added at a concentration of 150 x 10(4) cell.mL(-1). Larvae and exuviae of each zoeal stage were preserved in an alcohol 70% + glycerin (1:1) solution. The phyllosomas moulted eight times; the intermoulting period of each instar averaged about 7 to 10 days. The main morphological changes of each appendage were described in detail, illustrated and compared with previous reports.

Os estágios iniciais de lagosta tropical Panulirus echinatus eclodiram e foram cultivados em laboratório. Fêmeas ovígeras foram capturadas em seu habitat e cuidadosamente transportadas para o laboratório. As larvas foram cultivadas em tanques de recirculação de água e alimentadas com náuplios de Artemia e gônadas mexilhão Brachydonts sp. Microalga Dunaliella viridis foi adicionada em cada tanque de cultivo na concentração de 150 x 10(4) cel.mL-1. Os filosomas mudaram oito vezes e o período de intermuda de cada instar foi de cerca de 7 a 10 dias. As principais mudanças morfológicas de cada apêndice foram descritas, ilustradas e comparadas com trabalhos anteriores.

RESUMEN

Porencephalic cyst expanding into the ear is a very rare complication of temporal bone fracture. We report a case of a 20-year-old male who developed a traumatic porencephalic cyst of the temporal lobe expanding into the ear through a tegmen fracture in association with a cholesteatoma. The clinical presentation was otitic meningitis. This occurrence was not encountered in any of the cases reviewed in the literature. The diagnosis, pathogenesis, treatment and prognosis of this condition are reviewed.
