RESUMO

Hemorrhages are the first cause of perinatal deaths in French women. Thirteen percent of these deaths are not linked to obstetrical problems but rather to hemoperitoneum. These incidents are under-diagnosed and as a result, treatment is delayed and fetal and maternal mortality increases. We report three cases of patients, all White female in their last trimester of a non-problematic pregnancy presenting with hemoperitoneum and resulting in different outcomes. The analysis of published materials and of our cases leads us to infer that a diagnosis of hemoperitoneum must be considered in pregnant women when abdominal pain, symptoms of shock and a decrease in hemoglobin are associated. An immediate response and intensive care followed by hemostatic surgery give these patients the best chance to survive.

RESUMO

OBJECTIVES: To describe management and screening for high-risk patients concerning post-partum hemorrhage (PPH) and antenatal management for severe anemia, thrombopenia, bleeding disorders and anticoagulant therapy. METHODS: Bibliographic search restricted to French and English languages using Medline database and recommendations of medical societies. RESULTS: The appropriate place for delivery should be chosen after multidisciplinary concertation based on level of risk (especially past-history of severe PPH and bleeding disorder) and easy access to blood products (Professional Consensus). Prevention for severe anemia is mainly based on oral iron supplementation (grade B). Explorations are required in case of thrombopenia<100Giga/L (grade C). Patients with bleeding disorder require the assistance of a physician skilled in hemostasis for perinatal management (grade C). Preventive anticoagulant therapy has no impact on PPH risk and perimedullar analgesia is usually authorized 12hours after last injection (grade C). Curative anticoagulant therapy slightly increases PPH risk and perimedullar analgesia is authorized only after 24hours since last injection (Professional Consensus). CONCLUSION: Prenatal identification of high-risk patients concerning PPH implies multidisciplinary concertation to determine the most appropriate birthplace where technical and human resources are available.

RESUMO

Type 1 diabetes (T1D) is due to the loss of both beta-cell insulin secretion and glucose sensing, leading to glucose variability and a lack of predictability, a daily issue for patients. Guidelines for the treatment of T1D have become stricter as results from the Diabetes Control and Complications Trial (DCCT) demonstrated the close relationship between microangiopathy and HbA1c levels. In this regard, glucometers, ambulatory continuous glucose monitoring, and subcutaneous and intraperitoneal pumps have been major developments in the management of glucose imbalance. Besides this technological approach, islet transplantation (IT) has emerged as an acceptable safe procedure with results that continue to improve. Research in the last decade of the 20th century focused on the feasibility of islet isolation and transplantation and, since 2000, the success and reproducibility of the Edmonton protocol have been proven, and the mid-term (5-year) benefit-risk ratio evaluated. Currently, a 5-year 50% rate of insulin independence can be expected, with stabilization of microangiopathy and macroangiopathy, but the possible side-effects of immunosuppressants, limited availability of islets and still limited duration of insulin independence restrict the procedure to cases of brittle diabetes in patients who are not overweight or have no associated insulin resistance. However, various prognostic factors have been identified that may extend islet graft survival and reduce the number of islet injections required; these include graft quality, autoimmunity, immunosuppressant regimen and non-specific inflammatory reactions. Finally, alternative injection sites and unlimited sources of islets are likely to make IT a routine procedure in the future.

RESUMO

OBJECTIVE: To review the current research and formulate a rational approach to the physiopathology, cause and treatment of post-dural puncture headache (PDPH). DATA SOURCES: Articles published to December 2011 were obtained through a search of Medline for the MeSh terms "epidural blood-patch" and "post-dural puncture headache". STUDY SELECTION: Six hundred and eighty-two pertinent studies were included and 200 were analysed. DATA SYNTHESIS: Resulting of a dural tap after spinal anaesthesia or diagnostic lumbar puncture or as a complication of epidural anaesthesia, PDPH occurs when an excessive leak of cerebrospinal fluid leads to intracranial hypotension associated to a resultant cerebral vasodilatation. Reduction in cerebrospinal fluid volume in upright position may cause traction of the intracranial structure and stretching of vessels. Typically postural, headache may be associated to nausea, photophobia, tinnitus or arm pain and changes in hearing acuity. In severe cases, there may be cranial nerve dysfunction and nerve palsies secondary to traction on those nerves. The Epidural Blood-Patch (EBP) is considered as the "gold standard" in the treatment of PDHP because it induces a prolonged elevation of subarachnoid and epidural pressures, whereas such elevation is transient with saline or dextran. EBP should be performed within 24-48hours of onset of headache; the optimum volume of epidural blood appears to be 15-20mL. Severe complications following EBP are exceptional. The use of echography may be safety puncture. The optimum timing of epidural blood-patch, the resort of repeating procedure if the symptomatology does not disappear, the alternative to the conventional medical treatment need to be determined by future clinical trial.

RESUMO

Disulfiram is commonly used in the treatment of alcohol dependence. It induces aversive symptoms after alcohol ingestion: the "acetaldehyde syndrome". Most often "acetaldehyde syndrome" is moderate but severe life-threatening symptoms may occur in specific circumstances. We report the case of a serious "acetaldehyde syndrome" with shock compounded by the initial administration of dopamine. Discussion clarifies the pathophysiology and develops the therapeutic management.

RESUMO

Gallstones are commonly observed after rapid weight loss, particularly after bariatric surgery. Preventive measures of gallstone formation and potential related complications are still debated. This study aimed to propose a standardized strategy according to the results of the literature. Thus, preventive measures should be determined according to patient status (evaluated clinically and by routine ultrasound) and the type of bariatric surgery. Cholecystectomy should be performed in patients with symptomatic gallstones irrespective of the planned operation, or for asymptomatic gallstones during a gastric by-pass. In other settings, ursodesoxycholic acid should be given postoperatively for 6 months.

RESUMO

AIM: To undertake a proof-of-concept study to determine whether a removable offloading device (the Ransart boot) for the management of diabetic foot ulcers (DFU) was as effective as reports of non-removable devices. RESEARCH DESIGN AND METHODS: This observational study used the Ransart boot for patients with DFU, in seven specialist centres. If a patient had two or more ulcers, one was selected as the index ulcer. Ulcers were classified by the University of Texas (UT) system. RESULTS: There were 135 patients (mean age 60.3 +/- 11.4 years); 96 (71.1%) male. Median ulcer duration at presentation was 90 [interquartile range (IQR) 30-1825] days. Seven were lost to follow-up, seven developed other major illnesses and four died; outcomes were documented in the remaining 117. Eighty-two (70.1% of 117) healed, after a median (IQR) 60 (43-99) days, while 22 (18.8%) ulcers were resolved by amputation (one major). The remaining 13 (11.1%) patients were judged non-compliant. There was a close correlation between ulcer classification at baseline and both time to healing (P < 0.001 chi(2)-test) and amputation (P < 0.001; Spearman's rank correlation coefficient). There was a positive correlation between ulcer duration at presentation and time to healing (P < 0.02), UT class (P < 0.01), glycated haemoglobin (P < 0.02) and amputation (P < 0.04). CONCLUSIONS: Time to healing and incidence of amputation were comparable with those previously reported for non-removable devices. Given that a removable device is much more acceptable to the patient, the effectiveness, cost and acceptability of the removable devices, such as the Ransart boot, need to be compared with a non-removable device in a randomized trial.

RESUMO

Pseudohypoparathyroidism Ia (PHP Ia) is characterized by resistance to PTH and many other stimuli because of deficiency of stimulatory G protein alpha-subunit. To determine the incidence, natural history, and mechanism of C cell dysfunction in PHP, calcitonin assays were performed in six patients with PHP Ia and four with pseudopseudohypoparathyroidism from three unrelated families. Controls included healthy subjects and patients with PHP Ib or hypoparathyroidism. The mean basal level of calcitonin was higher in PHP Ia patients than in controls (95.3 +/- 112.7 vs. 3.7 +/- 2.4 pg/mL; P = 0.005; n < 10). In PHP Ia patients, calcitonin levels rose over the normal range (30 pg/mL) after pentagastrin infusion in five patients and remained normal in one. Familial medullary thyroid carcinoma was clinically, biologically, and ultrasonographically ruled out over a mean follow-up exceeding 3 yr. Genomic screening for RET protooncogene mutations failed to reveal any anomaly. The calcitonin infusion test, which induced a significant increase in plasma cAMP in controls 30 and 60 min after infusion, failed to produce this response in PHP Ia patients, suggesting that the action of calcitonin was specifically impaired. PHP Ia may therefore be an independent etiology of hypercalcitoninemia and hyperresponsiveness to pentagastrin infusion.

RESUMO

Most of the medical proposed for patients with primary hyperparathyroidism are inefficient or dangerous, with the exception of oestrogens and physiological doses of vitamin D in selected cases. PTH analogs, calcimimetic drugs and anti-PTH immunization now provide attractive management perspectives.

RESUMO

Ixodes trianguliceps, parasite of insectivores and rodent mammals seems to be distributed throughout France, except in the mediterranean low altitude areas. This tick which does not manifest any parasitic specificty, has meanwhile preferred hosts (Clethrionomys glareolus, especially). At low altitudes, it likes forests, hedge-rows and heaths and at higher altitudes (Subalpine and alpine), opened area may be densely inhabited. The authors study the numerous concerned vegetal associations and precise the tick's phenology, particularly in the Bas-Dauphiné. They also discuss the many hypothesis concerning the still unknown ecology of I. trianguliceps free instars.
