  • Hepatic Abscess Due to Streptococcus Anginosus and Eikenella Corrodens, Secondary to Gastric Perforation by a Fish Bone
    Publication . Gonçalves, RJ; Murinello, A; Gomes da Silva, S; Santos Coelho, J; Lopes Santos, A; Sá Damásio, H
    Introduction: Foreign-body ingestion is a common event, but in only less than 1% of the cases complications occur. Hepatic abscesses induced by foreign-body penetration are rare. To date, there are only 62 reported cases of hepatic abscess secondary to fish bone perforation of the gastrointestinal tract. Case presentation: A 78-year-old male patient was admitted due to high fever and vomiting for 2 days, along with frequent eructations for the past 3 months. Abdominal ultrasound showed a liver abscess in the left lobe, and computed tomography revealed a hyperdense linear image that crossed the superior wall of the gastric antrum, contacting the liver lesion, suggestive of a foreign body, probably a fish bone. Blood cultures were positive with isolation of Streptococcus anginosus and Eikenella corrodens. Ultrasound-guided percutaneous drainage of the abscess was done, and S. anginosus was isolated in the pus. Surgical debridement and fish bone removal were performed; the patient completed 21 days of antibiotic therapy, with a favorable evolution. Conclusion: To the best of our knowledge, this is the first reported case of liver abscess caused by fish bone penetration with isolation of S. anginosus and E. corrodens. Bacterial coaggregation is one of the mechanisms that can explain their ability for causing invasive infections away from the oral cavity, by increasing their resistance to the innate immune system and survival of both species.

  • Pneumoperitoneu em Doente sob Diálise Peritoneal
    Publication . Gomes da Silva, S; Nabais, C; Penedo, J
    O Pneumoperitoneu no doente em diálise peritoneal é uma complicação rara, no entanto deve ser tida em atenção de forma a evitar uma laparotomia desnecessária que possa comprometer esta opção dialítica. Os autores qpresentam o cado de uma doente de 70 anos de idade com insuficiência renal crónica, em diálise peritoneal há 21 meses, sem qualquer complicação ou sinal de peritonite. Admitida no serviço de urgência com dor epigástrica súbita. À observação, um abdómen timpanizado, sem alterações na porção externa do cateter de Tenckhoff. Analiticamente sem leucocitose. O Rx Abdominal demonstrou a existência de pneumoperitoneu. A TC abdominal confirmou uma pneumoperitoneu generalizado mas predominante no andar supramesocólico, sem extravasamento de contraste oral e com o cateter de diálise bem posicionado no quadrante inferior esquerdo. Procedeu-se à aspiração do pneumoperitoneu através de um técnica asséptica em posição de Trendlenburg, com confirmação radiológica da resolução do mesmo. Constatou-se recorrência do penumoperitoneu no dia seguinte, apesar da doente permanecer assintomática, pelo que se procedeu à remoção do cateter, sem recorrência do pneumoperitoneu.
