Acute respiratory failure involving an R variant of Mycobacterium abscessus.

We report the case of a cystic fibrosis patient colonized with a smooth-morphotype form of Mycobacterium abscessus who developed acute respiratory failure with the emergence of an isogenic rough (R) variant while he was recovering from peritonitis-induced shock. This report emphasizes the role of R forms in severe M. abscessus infections.

Necrotizing enterocolitis after antipsychotic treatment involving clozapine and review of severe digestive complications -- a case report.

A case of necrotizing enterocolitis in a 19-year old man treated for schizophrenic disorder, induced by a drug association involving clozapine and requiring surgical treatment, is presented. To our knowledge only few reports have described the occurrence of this complication with atypical antipsychotics. Evidence for linking this complication to clozapine was reinforced by the absence of any viral or bacterial infection.

Severe hypernatremia after hypertonic saline irrigation of hydatid cysts.

Patients with iatrogenic hypernatremia and serum sodium levels >170 mmol/L either die or sustain severe central nervous system damage. We report the first case of an adult patient who survived an extreme iatrogenic acute hypernatremia (200 mmol/L) resulting from a hypertonic saline irrigation of multiple intraabdominal hydatid cysts. It is a unique report of an intraoperatively developed serum sodium increase without subsequent neurological damage.

[Infectious complications after liver transplantation].

Infections after liver transplantation are frequent and represent the first cause of mortality. Bacterial and fungal infections are favourized by preoperative clinical status, surgical conditions, degree of immunosuppression, and surgical complications. Perioperative antibiotics and, for patients at risk, antifungal prophylaxis, reduce their indicidence.
