[Anticonvulsant hypersensitivity syndrome: an entity to be remembered].

Anticonvulsant hypersensitivity syndrome is an unpredictable, potentially fatal drug reaction to aromatic anticonvulsants such as carbamazepine, phenytoin and phenobarbital. The hallmark features include fever, eosinophilia, rash and involvement of one or more internal organs. Clearly established diagnostic criteria and treatment guidelines are lacking.

[A rare cause of gastric outlet obstruction: Bouveret's syndrome].

Bouveret's syndrome is a rare type of gallstone ileus in which a gallstone enters the intestinal tract via a cholecystoenteric fistula and is lodged in the duodenum or the stomach. Since the first description by León Bouveret in 1896, fewer than 200 cases have been described in the worldwide literature. Mortality is high, at 25%, but may be related to the advanced age of the typical patient and comorbidities, as well as diagnostic delay.

[Pain originating from the abdominal wall: a forgotten diagnostic option].

Chronic abdominal pain is a common clinical problem in primary care, and is usually referred to gastroenterologists or general surgeons. Although up to 20% of cases of idiopathic abdominal pain arise in structures of the abdominal wall, this is frequently overlooked as a possible cause. It includes pain arising from structures of the abdominal wall including skin, parietal peritoneum, cellular subcutaneous tissue, aponeuroses, abdominal muscles and somatosensorial innervation from lower dorsal roots.

[Filgrastim in refractory Crohn's disease with an intra-abdominal abscess].

The application of recombinant human granulocyte colony-stimulating factor (filgrastim) seems to be a safe, well tolerated and potentially effective therapy for active Crohn's disease. We report the case of an adolescent boy with Crohn's disease and intra-abdominal abscess associated who had a significant response to treatment with recombinant human granulocyte colony-stimulating factor after all standard treatments had failed.
