[Hemoperitoneum and pregnancy in a patient with von Willebrand's disease type 3].

A 24-year-old woman with type 3 (characterised by a blood level of von Willebrand factor less than 1%) was admitted to the surgical intensive care unit with an haemorrhagic shock. She was pregnant (Beta HCG = 115 Ul.L-1), the echography of the abdomen, soon after admission, revealed a haemoperitoeum. She underwent abdominal surgery after substitution treatment. The surgeon found an ovarian haemorrhagic cyst. Later the course of pregnancy was normal and she was delivered by caesarean section. We describe the therapeutic strategy of that care.

[Prenatal diagnosis of congenital diaphragmatic hernia: evaluation of the prognosis].

OBJECTIVE: The aim of this study was to evaluate prognostic prenatal factors of congenital diaphragmatic hernia. MATERIAL AND METHODS: We designed a retrospective study of 34 patients with congenital diaphragmatic hernia. The infants were delivered at the Edouard Herriot Hospital between September 1, 1994 and June 30, 1998. We excluded cases of pregnancy termination. After eliminating 4 cases, we studied 30. The factors studied were: polyhydramnios, transverse abdominal diameter, hepatic and umbilical vein deviation, mediastinal deviation, intrathoracic location of the stomach. Prenatal karyotype and echocardiography were systematically obtained. RESULTS: Total perinatal mortality was 53% and was 48% in case of unique diaphragmatic hernia. Prognosis was poorer if the diaphragmatic hernia was associated with another malformation (perinatal mortality: 80%, 4/5 cases), or in case of preterm delivery (83%, 5/6 cases). Factors associated with poor prognosis were: polyhydramnios, transverse abdominal diameter below the 5(th) percentile and major hepatic deviation. Diagnosis before 25 weeks was not associated with poor prognosis. Intrathoracic stomach was a good diagnostic sign, but did not allow an assessment of prognosis. CONCLUSION: Diagnosis of congenital diaphragmatic hernia was made before 25 weeks in 77% of the cases. It was not a factor of poor prognosis. As other authors, we found that prenatal association with another malformation (especially cardiac malformation) polyhydramnios, deviation of the liver, and abdominal transverse diameter below the 5(th) percentile were factors of poor prognosis. But it was difficult to determine the prenatal prognosis. Improvement is needed.

Are conventional targets for metabolic control sufficient to prevent fetal macrosomia during diabetic pregnancy?

We report the case of a 26 year-old woman, with an uncomplicated type 1 IDDM of 17 yr duration followed for her first pregnancy. At conception, HbA1c (measured by HPLC) was 6.5% and fructosamine was 280 u.mol.l (normal range below 285). During the follow-up, 15-days-interval frutosamine never exceeded the normal range and HbA1c values were under 6.5% excepted in the third trimester (7.0 +/- 0.8%) coinciding with a bad control of the 2 hours post-prandial blood glucose. A fetal macrosomy was discovered at 34 weeks of gestation and a heavy-for-date 4680 g baby was delivered by caesarean section at 38 weeks of gestation. Our case report outlines again the need to achieve the recommended target of metabolic control for the diabetic pregnant woman (blood preprandial glucose: 3.9-5.6 mM; post-prandial 2 h < 6.7 mM) specially during the third trimester of pregnancy. The use of computer databases might be helpful for precise monitoring during this narrow window period.

[Study of the toxicity and results of intraperitoneal hyperthermic chemotherapy in 28 patients with peritoneal carcinomatosis].

Based on a few previous studies, intra-peritoneal hyperthermic perfusion (IPHP) with Mitomycin C could become a beneficial treatment for peritoneal carcinomatosis. Twenty eight patients with peritoneal carcinomatosis arising from intra-abdominal cancers were treated by IPHP, Mitomycin C, diluted in 3 liters of saline solution warmed to a mean temperature of 45 degrees C, was injected into the abdominal cavity for one hour. Median survival for the whole series (postoperative mortality included) was 260 days. For patients with incomplete resection, median survival was 104 days. For patients with complete resection of carcinomatous nodules larger than 3 mm (19 patients), it was 450 days. In this group, actuarial survival was 56% at 1 year and 42% at 2 years. Only 5 (18%) of the 28 patients developed ascitic effusion during follow-up. These results confirm the efficacity of IPHP on ascitic effusion and on survival rate in patients with nearly complete resection of peritoneal carcinomatosis.

Ventilatory and waking responses to laryngeal stimulation in sleeping mature lambs.

Ventilatory and waking responses to laryngeal stimulation were studied in six chronically tracheostomized lambs breathing through an endotracheal tube. A balloon catheter inserted in the rostral tracheal segment allowed application of distilled water onto the larynx. Apnea, the main primary ventilatory response, was shorter in wakefulness (7.9 sec) than in quiet (10.7 sec) or active sleep (10.6 sec, residual variance = 3.29), where the response to laryngeal stimulation was poorly reproducible. Arousal delay measured from the neck muscle EMG was longer in active (21.1 sec) than in quiet sleep (5.4 sec, residual variance = 9.05). Arousal preceded apnea termination more often in quiet than in active sleep. When breathing resumed a sigh frequently occurred following prolonged apneas. We conclude that laryngeal stimulation elicits apnea in all states in mature lambs. The termination of apnea is related to waking up in quiet but not in active sleep, where arousal is depressed. A comparison of our results with data from preterm and adult mammals strongly suggests that the ventilatory response to laryngeal stimulation during active sleep is unaffected by maturation.
