[Staphylococcus lugdunensis necrotizing fasciitis after abdominal dermolipectomy: report of two cases and review of the literature]. / Fasciites nécrosantes à Staphylococcus lugdunensis après dermolipectomie abdominale : à propos de deux cas et revue de la littérature.

Necrotizing dermohypodermitis is a severe and potential fatal infection of soft tissues. We report two cases of 39- and 41-year-old patients operated of abdominal dermolipectomy and liposculpture after bariatric surgery. Because of a body mass index (BMI) less than 35kg/m(2), and trouble of interpretation of the SFAR recommendations, we have not achieved antibiotics. These patients presented an abdominal necrotizing dermohypodermitis at Staphylococcus lugdunensis, requiring wide excision of necrosis in emergency. The suites have been favorable after surgical and medical care. Perineal proximity, skin and subcutaneous peeling appear to be significant risk factors for this pathology. We suggest if case of abdominal dermolipectomy preventive measures in skin preparation and systematic antibiotics regardless of BMI. Indeed, the risk of a necrotizing dermohypodermitis recalls the importance of rigorous prevention and early diagnosis.

[Necrotizing dermohypodermitis of the abdominal wall in obesity. Two cases indicative of abdominopelvic deep infection]. / Dermo-hypodermites nécrosantes du tablier abdominal chez l'obèse. À propos de deux cas cliniques révélateurs d'infections profondes abdomino-pelviennes.

Necrotizing dermohypodermitis of abdominal wall in obese is a rare disease with high mortality. We report two cases of 50 and 62years old patients whose intra-abdominal infectious pathology (appendicular abscess for one and pyosalpinx for the other) was revealed by a necrotizing dermohypodermitis of the abdominal wall. The diagnosis has been established on the basis of converging clinical arguments (abdominal pain, crackles and necrotic appearance of abdominal wall in a septic shock context), linked with a CT-scan. The treatment consisted of a large excision of the abdominal wall necrosis and surgical eradication of deep infection source, with an intensive care and a broad spectrum antibiotic therapy. Both these patients present morbid obesity (BMI>40) whose implication must be taken into consideration in the way the disease appears. Indeed, the necrotizing dermohypodermitis of abdominal wall in these patients must lead first in looking for a deep infection with few symptoms. It must be identified quickly to propose an early and multidisciplinary surgical treatment.

[Open elbow dislocation with distal ischemia: a therapeutic emergency]. / Luxation ouverte du coude avec ischémie distale : une urgence thérapeutique.

We report the case of a 13-year-old boy with a traumatic elbow dislocation, open stage 2 (Cauchoix and Duparc), with distal ischemia. Exposure of the neurovascular humeral bundle through the wound accentutated the clinical emergency. This clinical observation consisted of elbow dislocation with all severity criteria: (i) opening of the skin, (ii) association with a fracture of the medial humeral epicondyle, and (iii) neurological deficit in the territory of the median nerve. The purpose of this report is to remind physicians that no investigation should delay surgery in elbow dislocation. Despite initial distal ischemia, no vascular exploration is required. Early reduction of the disloction is the key point of care.
