[Closed claims in obstetrics: A study based on French Sham insurance data]. / Sinistralité en obstétrique dans les hôpitaux publics français: données Sham.

OBJECTIVE: The aim of this study was to analyze the medicolegal claims related to obstetrics in French hospitals. MATERIAL AND METHODS: We did retrospective study on insurance claims provided by Sham insurances and which has been settled by a court over a 3-year period (2004-2006). RESULTS: We analyzed 66 closed claims that occurred between 1983 and 2005 in French hospitals (54 general hospitals and 12 academic). The average time between the declaration of the claim and the court conviction was 6 years. The average amount of compensation per claim was 500,000 €. The damage occurred during vaginal delivery (n=44), planned (n=5) or unplanned (n=4) cesarean. The more often claims are fetal asphyxia (n=24) or shoulder dystocia (n=8). The consequences are very important: cerebral palsy (16), death of the newborn (12), death of the mother (2) or brachial plexus injuries (6). CONCLUSION: The causes identified by the expert are always multifactorial with generally a misdiagnosis (n=27), a decision making error (n=36), a care error by the midwife (n=21) and/or a delay in medical care (n=13). These data should help strengthen the quality approach in obstetrics.

[Early rupture of a cryopreserved arterial allograft]. / Rupture précoce d'allogreffe artérielle cryopréservée: une complication à ne pas méconnaître.

Cryopreserved arterial allografts are used in vascular surgery to treat infected arterial prosthesis. This treatment reduces mortality and morbidity compared to conventional surgery. We observed a case of early rupture of the allograft with the death of the patient due to a misdiagnosis. Recent findings show that cases of rupture have been described, and that current cryopreservation protocols may be the cause of degeneration. To avoid a sudden death for the patient, this complication must be known to diagnose quickly and treat surgically before a final haemorrhagic shock.

[Diagnosis of ventilator-associated pneumonia: a prospective comparison of the telescoping plugged catheter with the endotracheal aspirate]. / Diagnostic non invasif des pneumopathies nosocomiales acquises sous ventilation mécanique: comparaison entre le prélèvement distal protégé et l'aspiration endotrachéale.

OBJECTIVE: Quantitative culture of endotracheal aspirates (EA) is widely accepted for the diagnosis of ventilator-associated pneumonia (VAP). The aim of the study was to compare the diagnostic accuracy of the EA with the blinded plugged telescoping catheter (PTC) in patients suspected of VAP. STUDY DESIGN: Prospective non-randomised observational study. PATIENTS AND METHODS: 31 patients suspected of having VAP underwent 46 bronchial samplings. An EA and a blinded PTC were performed successively in each case; the PTC result was taken as the reference standard. The EA and PTC cultures were defined positive if the result of bacterial cultures yielding were > or = 10(5) cfu.mL-1 and > or = 10(3) cfu.mL-1 respectively. RESULTS: The diagnosis of VAP could be established in 19 cases when PTC was taking as gold test. The overall agreement between the two techniques was 76%. EA had a sensitivity of 89.5%, a specificity of 66.7%, a negative predictive value of 90% and a positive predictive value of 65.4%. CONCLUSION: EA is a good diagnostic test when a non-invasive test has been chosen. The diagnosis of VAP could be excluded in 90% of cases when the EA cultures yielding were < 10(5) cfu.mL-1. His low specificity could drive in an over treatment of bronchopulmonar bacterial colonization. The accuracy of the EA compares well with that of the TPC for the diagnostic of VAP.

[Obesity, diabetes mellitus, and gas gangrene: a major therapeutic challenge]. / Gangrène gazeuse sur terrain d'obésité morbide et de diabète.

Soft tissue infections are uncommon but prognosis is severe (20 to 50%). Management consists in surgical debridement, antibiotic therapy against anaerobic and aerobic bacteria, and appropriate intensive care. When available, hyperbaric oxygen therapy is an integral part of the treatment. We report the case of 56-year-old female patient with diabetes (150 kg) was hospitalized in our unit a few days after surgical treatment of a buttocks abscess for clinical signs of peripheral gas gangrene. Surgical exploration showed necrotizing soft tissue infection with fasciitis. Adequate therapy using antibiotics, surgery daily and hyperbaric oxygen was given. Therapy had to be adapted to the patient's obesity. Outcome was good with recovery and few sequelae, allowing transfer to a medical ward.
