Incontinence urinaire chez la femme: prise en charge en médecine de premier recours [Urinary incontinence in women: management in primary care]

Urinary incontinence in women is a largely under-evaluated problem that affects nearly one out of two adult women. Even thouh its physiopathology is complex and its etiologies are multiple (and often intricate), urodynamic investigations are not considered necessary before starting a conservative therapy, which can be initiated by the primary care physician. Conservative management is based upon lifestyle modifications, specialized physiotherapy, and in certain cases medication. In the case of insufficient response after three months, the patient should be recommended to a specialist who can evaluate the need for a surgical procedure.

Prévention primaire et dépistage chez l'adulte: mise a jour 2014 [Primary prevention and screening in adults: update 2014].

Cet article propose une mise à jour des recommandations pour le bilan de santé et la prévention primaire et secondaire de nombreuses maladies cardiovasculaires et oncologiques. Les nouveautés pour le dépistage des cancers concernent essentiellement les cancers colorectal, du poumon et de la prostate. Pour la prévention des maladies cardiovasculaires, le dépistage de la sténose de l'artère carotidienne n'est toujours pas recommandé. Les preuves de la littérature sont insuffisantes pour recommander le dépistage de l'artériopathie coronarienne ou périphérique chez les patients asymptomatiques. Le partage de l'information et de la décision entre le médecin et le patient est à privilégier lorsqu'il existe une incertitude quant à l'efficacité d'une intervention. This article provides an update on the recommendations for the routine check-up and the primary and secondary prevention of cancer and cardiovascular disease. Changes for cancer screening affect mainly colorectal, lung and prostate cancers. In the area of cardiovascular disease prevention, screening for carotid artery stenosis is still not recommended. The current evidence is insufficient to recommend screening for coronary heart disease or peripheral artery disease in asymptomatic patients. Shared information and decision making between physician and patient is recommended when there is uncertainty regarding the effectiveness of an intervention.

Cost-effectiveness of pharmacotherapies for nicotine dependence in primary care settings: a multinational comparison.

OBJECTIVE: To estimate the incremental cost-effectiveness of the first-line pharmacotherapies (nicotine gum, patch, spray, inhaler, and bupropion) for smoking cessation across six Western countries-Canada, France, Spain, Switzerland, the United States, and the United Kingdom. DESIGN AND STUDY POPULATION: A Markov-chain cohort model to simulate two cohorts of smokers: (1) a reference cohort given brief cessation counselling by a general practitioner (GP); (2) a treatment cohort given counselling plus pharmacotherapy. Effectiveness expressed as odds ratios for quitting associated with pharmacotherapies. Costs based on the additional physician time required and retail prices of the medications. INTERVENTIONS: Addition of each first-line pharmacotherapy to GP cessation counselling. MAIN OUTCOME MEASURES: Cost per life-year saved associated with pharmacotherapies. RESULTS: The cost per life-year saved for counselling only ranged from US190 dollars in Spain to 773 dollars in the UK for men, and from 288 dollars in Spain to 1168 dollars in the UK for women. The incremental cost per life-year saved for gum ranged from 2230 dollars for men in Spain to 7643 dollars for women in the US; for patch from 1758 dollars for men in Spain to 5131 dollars for women in the UK; for spray from 1935 dollars for men in Spain to 7969 dollars for women in the US; for inhaler from 3480 dollars for men in Switzerland to 8700 dollars for women in France; and for bupropion from 792 dollars for men in Canada to 2922 dollars for women in the US. In sensitivity analysis, changes in discount rate, treatment effectiveness, and natural quit rate had the strongest influences on cost-effectiveness. CONCLUSIONS: The cost-effectiveness of the pharmacotherapies varied significantly across the six study countries, however, in each case, the results would be considered favourable as compared to other common preventive pharmacotherapies.

Metastatic primary adenocarcinoma of the bladder in a twenty-five years old woman.

Primary adenocarcinoma of the bladder is a rare tumor. The classification between primary vesical and urachal is debated. We present the case of a young female who presented clinicopathological features of a metastatic urachal adenocarcinoma, but the histological result revealed primary adenocarcinoma of the bladder contrary to expectancy. To the best of our knowledge this is the first reported case of a metastatic adenocarcinoma of the bladder in a 25 years old female. This case emphasizes the challenge for urologists to recognize and manage this aggressive tumor in the setting described.

Occult lung infarction may induce false interpretation of 18F-FDG PET in primary staging of pulmonary malignancies.

PURPOSE: The aim of the present report is to describe abnormal (18)F-fluorodeoxyglucose (FDG) accumulation patterns in the pleura and lung parenchyma in a group of lung cancer patients in whom lung infarction was present at the time of positron emission tomography (PET). METHODS: Between November 2002 and December 2003, a total of 145 patients (102 males, 43 females; age range 38-85 years) were subjected to whole-body FDG PET for initial staging (n=117) or restaging (n=11) of lung cancer or for evaluation of solitary pulmonary nodules (n=17). Of these patients, 24 displayed abnormal FDG accumulation in the lung parenchyma that was not consistent with the primary lesion under investigation (ipsilateral n=12, contralateral n=9 or bilateral n=3). Without correlative imaging, this additional FDG uptake would have been considered indeterminate in differential diagnosis. RESULTS: Of the 24 patients who were identified as having such lesions, six harboured secondary tumour nodules diagnosed as metastases, while in three the diagnosis of a synchronous second primary lung tumour was established. Additionally, nine patients were identified as having post-stenotic pneumonia and/or atelectasis (n=6) or granulomatous lung disease (n=3). In the remaining six (4% of all patients), a diagnosis of recent pulmonary embolism that topographically matched the additional FDG accumulation (SUV(max) range 1.4-8.6, mean 3.9) was made. Four of these six patients were known to have pulmonary embolism, and hence false positive interpretation was avoided by correlating the PET findings with those of the pre-existing diagnostic work-up. The remaining two patients were harbouring small occult infarctions that mimicked satellite nodules in the lung periphery. Based on histopathological results, the abnormal FDG accumulation in these two patients was attributed to the inflammatory reaction and tissue repair associated with the pathological cascade of pulmonary embolism. CONCLUSION: In patients with pulmonary malignancies, synchronous lung infarction may induce pathological FDG accumulation that can mimic active tumour manifestations. Identifying this potential pitfall may allow avoidance of false positive FDG PET interpretation.

Reoperative Roux-En-Y Gastric Bypass Provides Similar Long-Term Results as Primary Surgery

Background: The increasing prevalence of obesity worldwide is associated with a massive increase in the number of yearly performed bariatric procedures, many of them purely restrictive. Consequently, a growing number of surgical revisions are necessary, and conversion to Roux-en-Y gastric bypass (RYGBP) is a common option. So far, few series including mostly patients reoperated using open surgery,and limited follow-up, have been reported.Patients and methods: Retrospective analysis of prospectively collected data of all patients undergoing revisional RYGBP in our two departments.Results: Between June 1999 and February 2011, 186 patients were submitted to revisional RYGBP, 161 women and 25 men with a mean age of 43 years. Their mean initial BMI was 45,3 kg/m2, their mean nadir BMI between the index operation and revision was 34, and their mean pre-revision BMI was 38,5. The initial procedure was gastric banding in 134 (72 %) patients, VBG in 48 (25,8 %), RYGBP in 5 (2,7 %), and others in 3. The main indications for revision were complications from the primary procedure with or without weight regain. A laparoscopic approach was usedin 137 (73,7 %) cases. Overall early morbidity was 18,8 %, and major morbidity was 3,2 %. Comparing patients in the first, second and last third of our experience, the percentage of patients operated using a laparoscopic approach increased from 53,2 % to 71 % and finally 96,7 %, and overall morbidity decreased from 27,4 % to 24,2 % and then 4,8 %. There were more wound infections after laparotomy (22,4 versus 2,9 %, p<0,001). There was no mortality. The mean BMI remained between 30 and 32 up to nine years after revision. Up to this limit, a BMI of <35 was maintained in between 75 and 83 % of the patients.Conclusions: Revisional RYGBP proves to be an effective and safe procedure. It can be performed by laparoscopy in most cases, especially as experience increases., It is associated with an acceptable morbidity, though higher than with primary RYGBP. Long-term results are equivalent to those of primary RYGBP, and can be considered as very satisfactory considering the fact that, on average, patients requiring redo surgery represent a sub-selection of difficult bariatric patients.

Subclinical hypothyroidism and the risk of coronary heart disease and mortality.

CONTEXT: Data regarding the association between subclinical hypothyroidism and cardiovascular disease outcomes are conflicting among large prospective cohort studies. This might reflect differences in participants' age, sex, thyroid-stimulating hormone (TSH) levels, or preexisting cardiovascular disease. OBJECTIVE: To assess the risks of coronary heart disease (CHD) and total mortality for adults with subclinical hypothyroidism. DATA SOURCES AND STUDY SELECTION: The databases of MEDLINE and EMBASE (1950 to May 31, 2010) were searched without language restrictions for prospective cohort studies with baseline thyroid function and subsequent CHD events, CHD mortality, and total mortality. The reference lists of retrieved articles also were searched. DATA EXTRACTION: Individual data on 55,287 participants with 542,494 person-years of follow-up between 1972 and 2007 were supplied from 11 prospective cohorts in the United States, Europe, Australia, Brazil, and Japan. The risk of CHD events was examined in 25,977 participants from 7 cohorts with available data. Euthyroidism was defined as a TSH level of 0.50 to 4.49 mIU/L. Subclinical hypothyroidism was defined as a TSH level of 4.5 to 19.9 mIU/L with normal thyroxine concentrations. RESULTS: Among 55,287 adults, 3450 had subclinical hypothyroidism (6.2%) and 51,837 had euthyroidism. During follow-up, 9664 participants died (2168 of CHD), and 4470 participants had CHD events (among 7 studies). The risk of CHD events and CHD mortality increased with higher TSH concentrations. In age- and sex-adjusted analyses, the hazard ratio (HR) for CHD events was 1.00 (95% confidence interval [CI], 0.86-1.18) for a TSH level of 4.5 to 6.9 mIU/L (20.3 vs 20.3/1000 person-years for participants with euthyroidism), 1.17 (95% CI, 0.96-1.43) for a TSH level of 7.0 to 9.9 mIU/L (23.8/1000 person-years), and 1.89 (95% CI, 1.28-2.80) for a TSH level of 10 to 19.9 mIU/L (n = 70 events/235; 38.4/1000 person-years; P <.001 for trend). The corresponding HRs for CHD mortality were 1.09 (95% CI, 0.91-1.30; 5.3 vs 4.9/1000 person-years for participants with euthyroidism), 1.42 (95% CI, 1.03-1.95; 6.9/1000 person-years), and 1.58 (95% CI, 1.10-2.27, n = 28 deaths/333; 7.7/1000 person-years; P = .005 for trend). Total mortality was not increased among participants with subclinical hypothyroidism. Results were similar after further adjustment for traditional cardiovascular risk factors. Risks did not significantly differ by age, sex, or preexisting cardiovascular disease. CONCLUSIONS: Subclinical hypothyroidism is associated with an increased risk of CHD events and CHD mortality in those with higher TSH levels, particularly in those with a TSH concentration of 10 mIU/L or greater.

Hypertension artérielle pulmonaire primitive et maladie de Basedow [Primary pulmonary hypertension arterial and Basedow disease].

We report a case of a fifty year old woman with Graves' disease with positive AntiTPO antibodies and positive AntiTSH receptor antibodies, who was hospitalized with a right cardiac failure. A pulmonary hypertension was discovered on echocardiography. After adequate antithyroid therapy, the right cardiac failure regressed rapidly and pulmonary pressure normalised. An autoimmune process has often been proposed to explain the association between pulmonary hypertension and hyperthyroidism. We report the arguments supporting this autoimmune etiopathogenesis. We also discuss an other hypothesis based on a direct effect of thyroid hormones on the pulmonary circulation and the effects of high cardiac output associated with hyperthyroidism.

Second non-breast primary cancer following adjuvant therapy for early breast cancer: a report from the International Breast Cancer Study Group.

The incidence of second non-breast primary cancer following adjuvant treatment was evaluated using data from patients enrolled from 1978 to 1999 in four International Breast Cancer Study Group (IBCSG) trials. The occurrence of these tumours as sites of the first failure was assessed separately for two treatment comparisons: toremifene versus tamoxifen for 5 years in 1035 patients in IBCSG Trials 12-93 and 14-93 with a median follow-up of 8 years and endocrine therapy (toremifene or tamoxifen) versus chemo-endocrine therapy (CMF or AC plus toremifene or tamoxifen) in 1731 patients from IBCSG Trials III, VII and 12-93, with a combined median follow-up of 14 years. No significant differences in second non-breast primary tumours were observed in either comparison. In particular, the incidences of second primary uterine tumours with toremifene and tamoxifen were similar and no significant increase of secondary leukaemias was observed with chemo-endocrine therapy compared with endocrine therapy.

Productive HIV-1 infection of primary CD4+ T cells induces mitochondrial membrane permeabilization leading to a caspase-independent cell death.

We have explored in vitro the mechanism by which human immunodeficiency virus, type 1 (HIV-1) induces cell death of primary CD4+ T cells in conditions of productive infection. Although HIV-1 infection primed phytohemagglutinin-activated CD4+ T cells for death induced by anti-CD95 antibody, T cell death was not prevented by a CD95-Fc decoy receptor, nor by decoy receptors of other members of the TNFR family (TNFR1/R2, TRAILR1/R2/OPG, TRAMP) or by various blocking antibodies, suggesting that triggering of death receptors by their cognate ligands is not involved in HIV-induced CD4 T cell death. HIV-1 induced CD4 T cell shrinkage, cell surface exposure of phosphatidylserine, loss of mitochondrial membrane potential (Deltapsim), and mitochondrial release of cytochrome c and apoptosis-inducing factor. A typical apoptotic phenotype (nuclear chromatin condensation and fragmentation) only occurred in around half of the dying cells. Treatment with benzyloxycarbonyl-Val-Ala-Asp-fluoromethylketone, a broad spectrum caspase inhibitor, prevented nuclear chromatin condensation and fragmentation in HIV-infected CD4+ T cells and in a cell-free system (in which nuclei were incubated with cytoplasmic extracts from the HIV-infected CD4+ T cells). Nevertheless, benzyloxycarbonyl-Val-Ala-Asp-fluoromethylketone did not prevent mitochondrial membrane potential loss and cell death, suggesting that caspases are dispensable for HIV-mediated cell death. Our findings suggest a major role of the mitochondria in the process of CD4 T cell death induced by HIV, in which targeting of Bax to the mitochondria may be involved.

Physical activity, bodyweight, health and fear of negative evaluation in primary school children.

Fear of negative evaluation (FNE) is regarded as being the core feature of social anxiety. The present study examined how FNE is associated with physical activity (PA), body mass index (BMI) and perceived physical health (PPH) in children. Data were collected in a sample of 502 primary school children in first and fifth grades taking part in a randomized-controlled trial ("Kinder-Sportstudie KISS") aimed at increasing PA and health. PA was assessed by accelerometry over 7 days, PPH by the Child Health Questionnaire and FNE by the Social Anxiety Scale for Children--Revised. BMI z-scores were calculated based on Swiss norms. Cross-sectional analyses indicated that children high in FNE exercised less, reported lower levels of PPH and had higher BMI z-scores (P&lt;0.01). Using mixed linear models, the school-based PA intervention did not manage to reduce FNE scores. Overweight children demonstrated a greater increase in FNE (P&lt;0.05) indicating that enhanced weight may be a risk factor for FNE. In conclusion, the associations among high FNE, low PA and increased BMI should be considered when promoting an active lifestyle in children.
