Leiden Factor V mutation, associated with resistance to activated protein C, is a prothrombotic state found in 20% of the patients with a first episode of deep-vein thrombosis. We report the case of a 30-Year-old woman with a history of intermittent abdominal pain who developed small bowel infarction requiring extensive small bowel resection. Biological search for prothrombotic disorder showed resistance to activated protein C due to homozygosity for the factor V Leiden mutation. Long-term anticoagulant therapy was initiated. Unexplained abdominal pain may be due to venous mesenteric ischemia, which can be associated with factor V Leiden mutation.

We report five cases of herpetic esophagitis in human immunodeficiency virus non-infected patients. Herpetic esophagitis is a frequent infection in immunocompromised patients. However, sixty four cases of herpetic esophagitis have been reported in immunocompetent patients. The infection presents non-specific esophageal symptoms. Diagnosis relies on esophageal histology and viral cultures. Treatment by acyclovir is recommended to prevent severe complications. This infection is probably underestimated in immunocompetent hosts but seems to be more frequent in patients with severe illness that can be responsible for transitory immunodeficiency. Biopsies of esophageal lesions should be systematically performed in these patients.

Osteoma of the para-nasal sinuses is a rare and benign tumor that develops slowly. When therapy becomes mandatory, it is necessarily surgical and requires a standard external approach. This report analyses seven cases of operated osteomas, using different surgical techniques, adapted to different indications. Three patients underwent exclusive endonasal endoscopic surgery, and four patients had external surgery coupled with endonasal surgery. Results have proven successful with a four-year median follow-up. Epidemiological, clinical, histological and therapeutic considerations as well as the value of the endoscopic endonasal surgical approach are discussed. Endonasal endoscopic surgery can be used alone in naso-ethmoidal osteomas. It must, though, be associated with external standard procedure when the osteoma involves important extension to the frontal sinuses. In isolated frontal osteomas, external standard approach is mandatory for resection, endonasal technique being in this case contributive to the repermeabilisation of the infundibulum.
