Management of epithelial cancer of the ovary, fallopian tube, primary peritoneum. Long text of the joint French clinical practice guidelines issued by FRANCOGYN, CNGOF, SFOG, GINECO-ARCAGY, endorsed by INCa. (Part 2: systemic, intraperitoneal treatment, elderly patients, fertility preservation, follow-up).

Adjuvant chemotherapy by carboplatin and paclitaxel is recommended for all high-grade ovarian and tubal cancers (FIGO stages I-IIA) (grade A). After primary surgery is complete, 6 cycles of intravenous chemotherapy (grade A) are recommended, or a discussion with the patient about intraperitoneal chemotherapy, according to her risk-benefit ratio. After complete interval surgery for FIGO stage III, hyperthermic intraperitoneal chemotherapy (HIPEC) can be proposed, in accordance with the modalities of the OV-HIPEC trial (grade B). In cases of postoperative tumor residue or in FIGO stage IV tumors, chemotherapy associated with bevacizumab is recommended (grade A).

[Part II drafted from the short text of the French guidelines entitled "Initial management of patients with epithelial ovarian cancer" developed by FRANCOGYN, CNGOF, SFOG, GINECO-ARCAGY and endorsed by INCa. (Systemic and intraperitoneal treatment, elderly, fertility preservation, follow-up)]. / Partie 2 rédigée à partir de la synthèse de la recommandation nationale de bonnes pratiques cliniques intitulée « Conduites à tenir initiales devant des patientes atteintes d'un cancer épithélial de l'ovaire ¼ élaborée par FRANCOGYN, CNGOF, SFOG, GINECO-ARCAGY et labélisée par l'INCa.

Adjuvant chemotherapy with carboplatin and paclitaxel is recommended for all high-grade ovarian or Fallopian tube cancers, stage FIGO I-IIA (grade A). After a complete first surgery, it is recommended to deliver 6 cycles of intravenous (grade A) or to propose intraperitoneal (grade B) chemotherapy, to be discussed with patient, according to the benefit/risk ratio. After a complete interval surgery for a FIGO III stage, the hyperthermic intra peritoneal chemotherapy (HIPEC) can be proposed in the same conditions of the OV-HIPEC trial (grade B). In case of tumor residue after surgery or FIGO stage IV, chemotherapy associated with bevacizumab is recommended (grade A). For BRCA mutated patient, Olaparib is recommended (grade B).

Evaluation of the Xpert MTB/RIF assay for the diagnosis of smear-negative pulmonary and extrapulmonary tuberculosis in Madagascar.

OBJECTIVE: To evaluate the feasibility of the implementation of a commercial rapid molecular diagnostic test (Xpert MTB/RIF) for the routine diagnosis of smear-negative or extrapulmonary tuberculosis (TB) and its diagnostic accuracy, and to assess HIV prevalence in a real-life setting in Madagascar. This study was set in a tertiary care hospital in Madagascar. METHODS: A prospective cohort study was conducted of all consecutive cases with suspected smear-negative and/or extrapulmonary TB over a 2-year period. Cases were classified as proven, probable, or possible TB cases, or as having an alternative diagnosis. RESULTS: Of the 363 patients included, 183 (50.4%) had suspected smear-negative pulmonary TB and 180 (49.6%) had suspected extrapulmonary TB. For proven cases, the sensitivity, specificity, positive and negative predictive values of Xpert MTB/RIF were 82.4%, 98.8%, 98.3%, and 86.6%, respectively; for proven and probable cases grouped together, these values were 65%, 98.8%, 98.5%, and 64%, respectively. The diagnostic accuracy was slightly lower for extrapulmonary TB compared to smear-negative pulmonary TB. The prevalence of HIV infection was 12.1%, but almost half of these cases did not have TB (alternative diagnosis group). CONCLUSIONS: The implementation of a rapid diagnosis programme for TB in a resource-poor setting is feasible. The performance of the Xpert-MTB/RIF was remarkable in this difficult-to-diagnose population. HIV prevalence in this study was much higher than the prevalence reported in the general population in Madagascar, in patients with TB and patients with conditions other than TB.

Chemical activation with a combination of ionomycin and dehydroleucodine for production of parthenogenetic, ICSI and cloned bovine embryos.

The aim of this study was to evaluate the potential of dehydroleucodine (DhL), a new drug isolated from a medicinal herb used in Argentina, for activation of bovine oocyte. Several DhL concentrations and exposure times after ionomycin (Io) treatment were tested. The optimal DhL treatment, found for parthenogenetic development, was employed to produce bovine embryos by intracytoplasmic sperm injection (ICSI) and somatic cell nuclear transfer (SCNT). The best parthenogenic embryo developments were observed with 5 µM Io for 4 min followed by 5 µM DhL concentration and after 3-h exposure time (52.3% cleavage; 17.4% morulae; 7.3% blastocyst; n = 109). This treatment generated no significant differences with standard Io plus 6-dimethylaminopurine (DMAP) treatment in preimplantation embryo development. In our conditions, the embryo development reached after ICSI and SCNT assisted by the DhL treatment did not differ in terms of cleavage and blastocyst development from activation with standard Io plus DMAP treatment (p > 0.05). In conclusion, DhL utilization to activate oocytes and induce development of parthenogenotes, ICSI-embryos or SCNT-embryos is reported here for first time.

Correction of facial lipoatrophy using autologous fat transplants in HIV-infected adolescents.

OBJECTIVES: Antiretroviral therapy has dramatically improved the survival of HIV-infected children. Nevertheless, side effects comparable to those found in adults have been encountered, such as facial lipoatrophy, which can have a negative impact on the self-esteem of otherwise healthy adolescents. Cosmetic surgical procedures in adolescents raise psychological issues which need to be specifically addressed and which have never been previously reported in this population. We evaluated the patient satisfaction, safety and cosmetic results of HIV-infected adolescents who experienced autologous fat transplants for the correction of facial lipoatrophy. METHODS: We report the results of plastic surgery using autologous fat transplants (Coleman's Lipostructure) in six HIV-infected adolescents with facial lipoatrophy: three boys and three girls, aged 14-19 years. RESULTS: The quantity of reinjected fat on each side of the face varied from 5 to 12 mL within a single procedure. All the patients reported being satisfied or very satisfied with the cosmetic results and reported a positive impact on their daily life. CONCLUSIONS: With well-trained surgeons and carefully selected indications, corrective surgery of facial lipoatrophy in HIV-infected adolescents can provide immediate and long-lasting benefits in terms of physical appearance and psychological wellbeing, and should be considered as a component of comprehensive care.

Nutritional intervention to reduce the n-6/n-3 fatty acid ratio increases adiponectin concentration and fatty acid oxidation in healthy subjects.

BACKGROUND/OBJECTIVES: Consumption of n-3 polyunsaturated fatty acids (PUFA) has a favourable impact on inflammation and cardiovascular disease. However, the Western diet is characterized by a low n-3 PUFA intake and an imbalance in the n-6/n-3 PUFA ratio. Study the effect 10-week of diet modification to decrease the n-6/n-3 PUFA ratio on cardiovascular risk factors and resting energy expenditure. SUBJECTS AND METHODS: Ten-week dietary intervention in 17 healthy subjects. Dietary intake, euglycemic hyperinsulinemic clamp, indirect calorimetry, lipid profile, hormones, inflammatory markers and erythrocyte membrane fatty acid composition were recorded before and at the end of the intervention. Comparisons are between baseline and post-treatment levels. RESULTS: Dietary records of the linoleic acid/alpha-linolenic acid ratio (baseline: 32.2 (s.d. 3.7) vs post-intervention: 2.2 (s.d. 0.1), P<0.0001) and erythrocyte membrane fatty acid composition reflected good compliance. Dietary intervention was associated with significant reductions in TNF-alpha (baseline: 2.2 (s.d. 0.3), post-intervention: 1.5 (s.d. 0.3) pg/ml, P=0.01) and low-density lipoprotein-cholesterol (baseline: 2.5 (s.d. 0.2), post-intervention: 2.3 (s.d. 0.1) mmol/l, P=0.03) and increased adiponectin (baseline: 6.5 (s.d. 0.7), post-intervention: 7.6 (s.d. 0.6) microg/ml, P=0.02). Fasting lipid oxidation was increased (baseline: 0.7 (s.d. 0.1), post-intervention: 0.9 (s.d. 0.1) mg/kg x min, P=0.01), whereas glucose oxidation decreased in both fasting (baseline: 1.6 (s.d. 0.1), post-intervention: 1.3 (s.d. 0.1) mg/kg x min, P=0.02) and hyperinsulinaemic conditions (baseline: 3.6 (s.d. 0.1), post-intervention: 3.3 (s.d. 0.1) mg/kg x min, P=0.04). Insulin sensitivity was not affected by the intervention. CONCLUSION: A decreased n-6/n-3 PUFA ratio can be achieved with simple dietary counselling, resulting in multiple, potentially favourable effects on the metabolic and inflammatory profiles.

[Locoregional anesthesia]. / Anesthésie loco-régionale.

Local anaesthetics used for regional anaesthesia inhibit impulse depolarisation through blockade of sodium channels. Regional anaesthesia accounts for 20% of all anaesthetic procedures performed in France. Spinal anaesthesia is the most common technique used peroperatively, while epidural anaesthesia is used in labouring women and for postoperative pain control. Nerve stimulation allows a safer an easier approach to peripheral blocks. Regional anaesthesia is mainly indicated for limb or eye surgery, and for mildly invasive surgical procedures. Regional anaesthetic techniques are the most efficient to control postoperative pain and to facilitate patient rehabilitation. The risk related to the practice of regional anaesthesia compares with that of general anaesthesia and is thus very low. Main complications are epidural haematoma, cardiac arrest due to inadvertent intravascular injection of local anaesthestics, and peripheral nerve damage. Regional anaesthesia requires the same technical environment and careful monitoring as general anaesthesia.

5-Lipoxygenase gene expression in the thymus.

Eicosanoids are arachidonic acid metabolites issued both the cyclooxygenase and the lipoxygenase pathways. Many of these products were reported to modulate the immune response. Since most of eicosanoids have a short half life they are considered as local immunomodulators. Interactions between eicosanoids and thymocytes appear to be complex within the thymus. It was reported that cyclooxegenase derivatives of arachidonic acid are produced in this primary lymphoid organ mostly by cells of the thymic microenvironment. On the other hand it is not yet clearly established (1) what is the location of the lipoxygenase-positive cells within the gland and (2) what is the ratio of cells producing lipoxygenase metabolites of arachidonic acid when compared to the whole thymocyte population. Using two oligonucleotides complementary to the rat 5-lipoxygenase mRNA we demonstrated (by both hybridization on Northern blots and in situ hybridization) the expression of the 5-lipoxygenase gene in the thymus. 5-lipoxygenase positive cells appear to be associated in "clusters" and are mostly located in the thymic cortex. It is likely that they belong to the thymic microenvironment.

Low molecular weight heparin fractions as an alternative therapy in heparin-induced thrombocytopenia.

Eight patients with a delayed-onset heparin-induced thrombocytopenia, with thrombotic complications requiring immediate anticoagulation in 7 of them, were given low molecular weight heparin (LMWH) fractions as alternative therapy. This treatment led to normalization of platelet count within 3-5 days in 6 patients with clinical recovery in 5. In 2 patients, thrombocytopenia persisted despite LMWH therapy. In vitro platelet aggregation tests performed in all patients gave evidence of a relationship between the presence (or absence) of a LMWH-dependent platelet-aggregating factor in the patients' plasma and the persistence (or correction) of the thrombocytopenia with LMWH therapy. Although positive in vitro tests may not necessarily be associated with thrombocytopenia, in vitro testing may prove to be a useful guide before giving LMWH fractions as an alternative therapy in patients with heparin-induced thrombocytopenia requiring immediate anticoagulation.

[Acute adult respiratory distress syndrome after lymphography]. / Syndrome de détresse respiratoire aiguë de l'adulte après lymphographie.

Pulmonary complications of lymphography are usually described as radiological infiltrates without clinical symptoms. However, a case is here reported of an adult respiratory distress syndrome occurring after lymphography in a 60 year old female lymphoma patient. Pulmonary oedema developed within 48 h; haemodynamic study showed a normal capillary wedge pressure. The patient died from intractable low cardiac output within 24 h. Post-mortem examination showed pulmonary lymphocytic infiltration and multiple fat emboli. The lack of lymphatic drainage was probably responsible for the intravascular passage of lipid-soluble contrast medium, this giving endothelial lesions. In such patients with preexisting lung disease or pulmonary involvement in haematological disease, lymphography has to be considered carefully.

Antihypertensive effect of fractionated sublingual administration of nifedipine in moderate essential hypertension.

The magnitude and duration of the antihypertensive effect of nifedipine were studied in 7 cases of moderate essential hypertension. In a double-blind crossover study, nifedipine 10 mg or a placebo were administered sublingually 4 times a day for 2 days, and the results were compared. Each dose of nifedipine reduced systolic and diastolic blood pressure by 14% both in the supine and upright positions. The antihypertensive action lasted for about 3 h and it was not cumulative. The reduction in blood pressure was associated with a temporary increase in heart rate. Administration of nifedipine 10 mg did not significantly raise plasma renin activity or plasma aldosterone. The drug was well tolerated and no side effects were detected.
