Dépistage du cancer du sein par l'examen physique: qui en bénéficie? [Physical examination in screening for breast cancer: who benefits?].

A survey was undertaken among a representative sample of the female population, aged 20 to 74, of the Canton of Vaud, Switzerland (total population 550,000) to assess the knowledge, attitudes and practices of women in respect to breast cancer and its prevention. The present study focuses on access by women to medical preventive measures (breast examination by physician and information on breast self-examination). The data are analyzed in relation to the individual risk factors affecting women, in particular age. While with age the risk of breast cancer grows in a linear fashion, the proportion of women having their breast examined by a physician declines. Women over 50 who had no children before the age of 30 constitute an especially high risk category, with the lowest access to information and prevention. This is explained in large part by the fact that they consult gynecologists less often. In this regard it should be noted that a visit to a gynecologist's office is associated much more often with breast examination than a visit to a family physician. It is important to take such findings into account in providing more appropriate and complete care for those groups. This involves sensitization of the physician and improved information for the women themselves.

Estudio longitudinal del síndrome metabólico tras el trasplante renal.

BACKGROUND: The occurence of the metabolic syndrome (MS) between the renal receptors is one of the major complications after transplantation and is associated with an increased risk of graft failure and high rates of obesity and diabetes new appearance. AIMS: This study aims to investigate the prevalence and risk factors associated with the development of the MS and to evaluate the association between the same with the allograft dysfunction. METHODS: The samples consisted of 138 renal transplant patients, 83 men and 55 women, kidney transplant, which was attended by over five years for the transplant consultation. Were analyzed as potential risk factors for MS: age, sex, body mass index (BMI), weight, hypertension, diabetes, LDL, HDL, triglycerides in serum and immunosuppressive therapy (cyclosporine, tacrolimus, mycophenolate mofetil), was also assessed the prevalence of acute rejection episodes and renal function. RESULTS: The prevalence of MS was 39.85 %. As statistically significant risk factors were obtained the BMI, overweight, HDL cholesterol levels, triglycerides and LDL as well as hypertension and diabetes. There were high rates of acute rejection and differences in story to the glomerular filtration rate. CONCLUSIONS: There is a high prevalence of the MS that severely compromised renal function and graft survival in renal transplant patients, it is very important the control and strict monitoring of all risk factors identified.

Efectividad comparativa del seguimiento remoto a personas con marcapasos cardíacos frente al convencional: calidad de vida a los 6 meses.

BACKGROUND The use of remote follow-up (RF) of people with pacemakers (PM) is limited in comparison to the hospital modality (HS), being still poor the scientific evidence that shows their comparative effectiveness. The aim of this study was to compare the quality of life in individuals with different modalities of follow-up. METHODS Controlled, not randomized nor masked clinical trial, with data collection at pre and post-implantation of pacemakers during the 6 months follow-up. All patients over 18 years-old who were implanted a PM during the study period were selected (n = 83), and they were assigned to RF (n = 30) or HF (n = 53) groups according to their personal characteristics and patient's preferences. Baseline characteristics and number of visits to the hospital were analysed, the EuroQol-5D (EQ5D) questionnaire was administered to evaluate the health-related quality of life, and Duke Activity Status Index (DASI) to assess the functional capacity. RESULTS There were no significant differences between both groups in relation to the baseline analysis, EQ5D (RF:0.7299; HF:0.6769) and DASI (RF:21.41; HF:19.99). At 6 months the quality of life was improved in both groups (EQ5D RF:0.8613; HF:0.8175; p = 0,439) still without significant differences between them. DASI score was similar to baseline (20.51 vs 21.80). RF group performed less transmissions/visits per patient (1.57) than hospital group (1.96; relative reduction 31%; p = 0.015). CONCLUSIONS Remote follow-up of people with pacemakers might be considered as an equivalent option to the hospital follow-up in relation to the quality of life and it reduces the number of hospital visits.

Role of double-balloon enteroscopy in malignant small bowel tumors.

AIMTo assess the double-balloon enteroscopy (DBE) role in malignant small bowel tumors (MSBT). METHODS This is a retrospective descriptive study performed in a single center. All consecutive patients who underwent a DBE with final diagnosis of a malignant neoplasm from 2004 to 2014 in our referral center were included. Patient demographic and clinical pathological characteristics were recorded and reviewed. MSBT diagnosis was achieved either by DBE directed biopsy with multiple tissue sampling, endoscopic findings or histological analysis of surgical specimen. We have analyzed double-balloon enteroscopy impact in outcome and clinical course of these patients. RESULTS Of 627 patients, 28 (4.5%) (mean age = 60 ± 17.3 years) underwent 30 procedures (25 anterograde, 5 retrograde) and were diagnosed of a malignant tumor. Patients presented with obscure gastrointestinal bleeding (n = 19, 67.9%), occlusion syndrome (n = 7, 25%) and diarrhea (n = 1, 3.6%). They were diagnosed by DBE biopsy (n = 18, 64.3%), histological analysis of surgical specimen (n = 7, 25%) and unequivocal endoscopic findings (n = 2, 7.1%). Gastrointestinal stromal tumor (n = 8, 28.6%), adenocarcinoma (n = 7, 25%), lymphoma (n = 4, 14.3%), neuroendocrine tumor (n = 4, 14.3%), metastatic (n = 3, 10.7%) and Kaposi sarcoma (n = 1, 3.6%) were identified. DBE modified outcome in 7 cases (25%), delaying or avoiding emergency surgery (n = 3), modifying surgery approach (n = 2) and indicating emergency SB partial resection instead of elective approach (n = 2). CONCLUSION DBE may be critical in the management of MSBT providing additional information that may be decisive in the clinical course of these patients.

Exposition au VIH, à l'hépatite B et C au cabinet médical et à l'hôpital. Prévention et prophylaxie postexpositionnelle [Exposure to HIV, hepatitis B and C in office practice and hospital. Prevention and post-exposure prophylaxis]

Suite à un accident exposant à du sang (piqûre; coupure), provenant d'un patient infecté, le risque d'infection par VIH est d'environ 0,3% et par le virus de l'hépatite C (VHC) d'environ 0,5%. Chez les personnes vaccinées avec une réponse immunitaire adéquate (titre d'anticorps HBs >100 mUI/ml), aucune infection professionnelle par hépatite B n'a été reconnue en Suisse. La plupart des infections par VIH et VHB peuvent être prévenues par un traitement d'urgence et une prophylaxie postexpositionnelle (PEP). Il n'y a actuellement aucune prophylaxie postexpositionnelle pour le VHC. En cas de transmission de VHC, un traitement rapide par peginterféron et ribavirine est à envisager. Chaque hôpital et cabinet médical doivent mettre sur pied un système pour assurer une prise en charge optimale et en urgence des blessures par piqûres ou coupures. Lors de blessures accidentelles avec du sang de patients séropositifs pour le VIH et dans des situations complexes, il est recommandé de consulter un médecin du personnel ou un infectiologue expérimenté. The risk of infection after an occupational needle stick injury with blood from an infected source patient is approximately 0.3% for HIV and 0.5% for hepatitis C virus (HCV). In Switzerland no cases of occupational HBV infection have been recorded in fully vaccinated persons with a documented adequate vaccine response (HBsantibody titer >100 mIU/mL). Most occupational HIV und HBV infections can be prevented by appropriate emergency measures and post-exposure prophylaxis (PEP). No HCV-PEP is currently available. Early therapy with peginterferon and ribavirin should be considered in cases of occupational HCV seroconversion. Every hospital and office practice should establish a system for 24 h/24 h emergency management of occupational needle stick injuries. In the setting of an HIV-seropositive source patient and in complex situations, early consultation with a specialist in occupational medicine or infectious diseases should be considered.

IVA in addition to BMD can change the osteoporosis management in 25% of clinical routine patients

Introduction Vertebral fracture is one of the major osteoporoticfractures which are unfortunately very often undetected. In addition,it is well known that prevalent vertebral fracture increases dramaticallythe risk of future additional fracture. Instant Vertebral Assessment(IVA) has been introduced in DXA device a couple of years ago toease the detection of such fracture when routine DXA are performed.To correctly use such tool, ISCD provided clinical recommendationon when and how to use it. The aim of our study was to evaluate theISCD guidelines in clinical routine patients and see how often itmay change of patient management.Methods During two months (March and April 2010), a medicalquestionnaire was systematically given to our clinical routine patientto check the validity of ISCD IVA recommendations in our population.In addition, all women had BMD measurement at AP spine,femur and 1/3 radius using a Discovery A System (Hologic, Waltham,USA). When appropriate, IVA measurement had been performedon the same DXA system and had been centrally evaluated by twotrained doctors for fracture status according to the semi-quantitativemethod of Genant. The reading had been performed when possiblebetween L5 and T4.Results Out of 210 women seen in the consultation, 109 (52 %)of them (mean age 68.2 ± 11.5 years) fulfilled the necessary criteriato have an IVA measurement. Out of these 109 women, 43 (incidence39.4 %) had osteoporosis at one of the three skeletal sitesand 31 (incidence 28.4 %) had at least one vertebral fracture. 14.7 %of women had both osteoporosis and at least one vertebral fractureclassifying them as "severe osteoporosis" while 46.8 % did not haveosteoporosis and no vertebral fracture. 24.8 % of the women hadosteoporosis but no vertebral fracture while 13.8 % of women didhave osteoporosis but vertebral fracture (clinical osteoporosis).Conclusions In 52 % of our patients, IVA was needed accordingto ISCD criteria. In half of them the IVA test influenced of patientmanagement either may changing the type of treatment of simplyby classifying patient as "clinical osteoporosis". IVA appears to bean important tool in clinical routine but unfortunately is not yetvery often use in most of the centers.

Revised definitions of invasive fungal disease from the European Organization for Research and Treatment of Cancer/Invasive Fungal Infections Cooperative Group and the National Institute of Allergy and Infectious Diseases Mycoses Study Group (EORTC/MSG) Consensus Group.

BACKGROUND: Invasive fungal diseases are important causes of morbidity and mortality. Clarity and uniformity in defining these infections are important factors in improving the quality of clinical studies. A standard set of definitions strengthens the consistency and reproducibility of such studies. METHODS: After the introduction of the original European Organization for Research and Treatment of Cancer/Invasive Fungal Infections Cooperative Group and the National Institute of Allergy and Infectious Diseases Mycoses Study Group (EORTC/MSG) Consensus Group definitions, advances in diagnostic technology and the recognition of areas in need of improvement led to a revision of this document. The revision process started with a meeting of participants in 2003, to decide on the process and to draft the proposal. This was followed by several rounds of consultation until a final draft was approved in 2005. This was made available for 6 months to allow public comment, and then the manuscript was prepared and approved. RESULTS: The revised definitions retain the original classifications of "proven," "probable," and "possible" invasive fungal disease, but the definition of "probable" has been expanded, whereas the scope of the category "possible" has been diminished. The category of proven invasive fungal disease can apply to any patient, regardless of whether the patient is immunocompromised, whereas the probable and possible categories are proposed for immunocompromised patients only. CONCLUSIONS: These revised definitions of invasive fungal disease are intended to advance clinical and epidemiological research and may serve as a useful model for defining other infections in high-risk patients.

Male sexuality-related concerns: what use of the internet?

Purpose: Although young males encounter sexually-related concerns, they are mostly absent from specialized services. Our objective is to assess whether the internet is used by boys to find answers to these types of problems and questions. Methods: In the context of a qualitative study assessing young males' barriers to access sexual and reproductive health facilities, we conducted two focus groups gathering 12 boys aged 17-20. Discussions were triggered through the presentation of four vignettes corresponding to questions posted by 17-20 year old boys and girls on an information website for adolescents (www.ciao.ch), concerning various sexual dysfunction situations. In order to avoid having to talk about their own experience, participants were asked what they would do in those cases. Results: In general, the internet was mentioned quite thoroughly as a means of searching for information through research engines and a place to address professionals for advice.Within the hierarchy of consultation possibilities, the internet was given the first place as a way to deal with these types of problems presenting many advantages: (1) the internet enables to maintain intimacy; (2) it is anonymous (use of a pseudo); (3) it avoids having to confront someone face-to-face with personal problems which can be embarrassing and challenging for one's pride; (4) it is free; and (5) it is accessible at all times. In other words, participants value the internet as a positive tool to avoid many barriers which prevent offline consultations to take place. Most participants consider the internet at least as a first step in trying to solve a problem; for instance, by better defining the seriousness of a problem and judging if it is worth consulting a doctor. However, despite the positive qualities of the internet, they do put forward the importance of having specialists answering questions, trustworthiness, and being followed-up by the same person. Participants suggested that a strategy to break down barriers for boys to consult in face-to-face settings is to have a consultation on the internet as a first step which could then guide the person to an in-person consultation if necessary. Conclusions: The internet as a means of obtaining information or consulting received high marks overall. Although the internet cannot replace an in-person consultation, the screen and the keyboard have the advantage of not involving a face-to-face encounter and raise the possibility of discussing sexual problems anonymously and in private. The internet tools together with other new technologies should continue to develop in a secure manner as a space providing prevention messages and to become an easy access door to sexual and reproductive health services for young men, which can then guide youths to appropriate resource persons. Sources of support: This study was supported by the Maurice Chalumeau Foundation, Switzerland.

Is a pre-anaesthetic information form really useful ?

Background: All patients should be fully informed about the risks and benefits of anaesthetic procedures before giving a written consent. Moreover, the satisfaction level may vary in proportion to the information given. We aimed to determine, in a single-blind randomized-controlled study, whether an information form given before the pre-anaesthetic consultation could improve perceived information, information gain and satisfaction level. Methods: Two hundred patients ASA 1-3 scheduled for an elective orthopaedic surgery were randomized into two groups: a group that received an information form before the pre-anaesthetic consultation (IF group) and a control group (no information form). A standardized questionnaire was submitted after the pre-anaesthetic consultation and after the operation. This 17-item questionnaire explored perceived information (five items), information gain (three items) and satisfaction level (nine items). The items of each topic were pooled and compared between groups. Results: One hundred and eighty-five patients (92.5%) completed the study. The IF group had better perceived information (IF group 73% vs. control group 63%, P=0.002), higher information gain (IF group 75% vs. control group 62%, P=0.001) and a higher satisfaction level (IF group 95% vs. control group 92%, P=0.048). Conclusions: Our study suggests that an information form given before the pre-anaesthetic consultation enhances perceived information, information gain and satisfaction level. Méthode Cette étude prospective randomisée en simple aveugle a été conduite à l'hôpital Orthopédique du Centre Hospitalier Universitaire Vaudois. Deux cents patients prévus pour une chirurgie élective orthopédique ont été recrutés entre avril et juin 2008 et repartis en deux groupes selon une table de randomisation : un groupe recevait une feuille d'information 30 minutes avant la consultation préanesthésique, et l'autre pas. Les patients des deux groupes étaient ensuite examinés à la consultation preoperatoire par un anesthésiste indépendant de l'étude, puis recevaient un questionnaire standardisé. Ce questionnaire, issu de questionnaires existants, et validé préalablement sur un échantillon de 50 patients, comportait 17 questions qui exploraient la perception- de l'information (5 questions), le gain d'information (3 questions) et le niveau de satisfaction (9 questions) Parmi ces 17 questions, 3 étaient posées 24 h après l'intervention chirurgicale lors d'une visite dans la chambre ou lors d'un contact téléphonique. Les réponses étaient analysées et comparées entre les deux groupes. Résultats Cent huitante-cinq patients ont terminé l'étude. Le groupe qui a reçu la feuille d'information avait une meilleure perception de l'information (73% vs 63% dans le groupe de contrôle, ρ = 0 002) un gain d'information plus élevé (75% vs. 62% dans le groupe de contrôle, ρ = 0.001) et un niveau de satisfaction plus élevé (95% vs. 92% dans le groupe de contrôle, ρ= 0.048). Discussion et conclusion Cette étude a permis de démontrer que la remise d'une feuille d'information explicative avant la consultation préanesthésique était un moyen simple et bon marché pour améliorer la perception de l'information et le niveau de satisfaction.

Infections nosocomiales en médecine ambulatoire: importance et prévention [Importance and prevention of nosocomial infections in the outpatient setting]

The concept of nosocomial infections (or healthcare-related infections) applies to the outpatients clinics. However, data are scarce and imprecise in this setting compared with hospitals. The choice of preventive measures is therefore difficult. A lower risk in the outpatient facilities does not justify the complete implementation of hospital precautions. The latter can nevertheless be adapted since infection may be acquired during an ambulatory consultation through the same mechanisms as in hospitals. We propose a preventive strategy derived from standard precautions to be applied in every case, transmission-based precautions that are more rarely needed, and asepsis in case of invasive procedure.

Androgen dependence of hirsutism, acne, and alopecia in women : retrospective analysis or 228 patients investigated for hyperandrogenism

RAPPORT DE SYNTHESE : L'hirsutisme, l'acné et l'alopécie chez la femme sont souvent associés à des troubles menstruels et à une production excessive d'androgènes, raison pour laquelle ces symptômes cutanés font l'objet d'évaluation endocrinienne. L'hyperandrogénie affecte 5 à 10 % des femmes en âge de reproduction et constitue un motif fréquent de consultation. Récemment, les sociétés d'endocrinologie ont émis des recommandations sur l'investigation et le traitement de l'hyperandrogénie. Longtemps confrontés à la demande de patientes souffrant d'hirsutisme, d'acné ou d'alopécie, nous avons décidé d'effectuer une approche diagnostique et thérapeutique comportant des dosages hormonaux et un traitement antiandrogénique. Un grand nombre de patientes a été ainsi étudié au fil des années. Les paramètres mesurés incluaient la testostérone plasmatique totale, l'androstènedione, le sulfate de déhydroépiandrostérone (DHEAS), la sex hormone-binding globulin (SHBG) et la testostérone salivaire. Cette dernière est considérée comme un bon reflet de la testostérone libre plasmatique, indépendamment des protéines de liaison. L'analyse rétrospective des dossiers nous a permis de comparer nos données avec celles de la littérature. Des 318 dossiers de patientes ayant consulté notre Service pour hirsutisme, acné ou alopécie pendant 6 ans, 228 ont pu être retenus pour une évaluation adéquate. Chez les patientes présentant ces symptômes de façon isolée, les taux d'androgènes et la prévalence de l'oligo-aménorhée étaient plus élevés en cas d'hirsutisme qu'en cas d'alopécie, avec des valeurs intermédiaires en cas d'acné. Aucun des androgènes mesurés ne permettait, à lui seul, d'identifier tous les cas d'hyperandrogénie, mais la testostérone salivaire a montré la meilleure corrélation positive avec l'hirsutisme, alors que la testostérone plasmatique totale montrait la moins bonne corrélation, et l'androstènedione, le DHEAS et la SHBG des corrélations intermédiaires (corrélation négative pour la SHBG). De plus, au cours du traitement antiandrogénique, la testostérone salivaire a montré l'abaissement proportionnel le plus marqué de tous les androgénes mesurés. Comparées aux patientes originaires d'Europe centrale, les patientes originaires d'Europe du sud consultaient avec des degrés d'hirsutisme supérieurs, mais aucune différence n'a été observée dans les corrélations entre l'hirsutisme et les taux hormonaux de ces deux groupes. En l'absence d'un nombre suffisant d'échographies ovariennes, .la prévalence du syndrome des ovaires polykystiques a été probablement sous-estimée (63 patientes, 27.6 % des cas), au bénéfice du diagnostic d'hyperandrogénie avec euménorrhée (101, 44.3 %); les autres diagnostics étaient: androgénes normaux (51, 22.4%), SHBG basse isolée (7, 3.1%), hyperplasie surrénalienne congénitale non-classique (4, 1.8%), et tumeur ovarienne (2, 0.9%). Nous avons comparé les divers traitements médicaux de l'hirsutisme publiés au cours des 25 dernières années, quant à leur efficacité et leur coût. La sensibilisation à l'insuline avec metformin est moins efficace, mais aussi moins chère. L'anti-androgène flutamide et l'inhibiteur de la 5-α reductase finastéride figurent parmi les traitements les plus performants, mais ils sont aussi les plus chers. Le traitement anti-androgénique et de suppression hormonale avec acétate de cyprotérone et éthinyloestradiol, utilisé dans cette étude, est également parmi les plus efficaces, tout en étant nettement moins cher. Cette étude est la première comparant directement les taux d'androgènes et la prévalence de l'oligoaménorrhée dans les 3 symptômes cutanés d'hyperandrogénie, hirsutisme, acné et alopécie, et elle démontre leur différente dépendance aux androgènes. La salive apparait comme un milieu de choix pour identifier ces patientes et la recommandation actuelle de doser la testostérone plasmatique totale en premier, pour distinguer l'hyperandrogénie de l'hirsutisme idiopathique, nous paraît inadéquate. Nous proposons, au contraire, d'abandonner ce dosage au profit de celui de la testostérone salivaire. Par ailleurs, notre étude infirme l'hypothèse d'une sensibilité cutanée accrue aux androgènes chez les femmes originaires du sud de l'Europe. Finalement, elle est la seule à comparer les effets cliniques, les changements biologiques et le coût annuel des traitements publiés de l'hirsutisme.

Statins for cardiovascular prevention according to different strategies: a cost analysis.

Background: Several studies have shown that treatment with HMG-CoA reductase inhibitors (statins) can reduce coronary heart disease (CHD) rates. However, the cost effectiveness of statin treatment in the primary prevention of CHD has not been fully established. Objective: To estimate the costs of CHD prevention using statins in Switzerland according to different guidelines, over a 10-year period. Methods: The overall 10-year costs, costs of one CHD death averted, and of 1 year without CHD were computed for the European Society of Cardiology (ESC), the International Atherosclerosis Society (IAS), and the US Adult Treatment Panel III (ATP-III) guidelines. Sensitivity analysis was performed by varying number of CHD events prevented and costs of treatment. Results: Using an inflation rate of medical costs of 3%, a single yearly consultation, a single total cholesterol measurement per year, and a generic statin, the overall 10-year costs of the ESC, IAS, and ATP-III strategies were 2.2, 3.4, and 4.1 billion Swiss francs (SwF [SwF1 = $US0.97]). In this scenario, the average cost for 1 year of life gained was SwF352, SwF421, and SwF485 thousand, respectively, and it was always higher in women than in men. In men, the average cost for 1 year of life without CHD was SwF30.7, SwF42.5, and SwF51.9 thousand for the ESC, IAS, and ATP-III strategies, respectively, and decreased with age. Statin drug costs represented between 45% and 68% of the overall preventive cost. Changing the cost of statins, inflation rates, or number of fatal and non-fatal cases of CHD averted showed ESC guidelines to be the most cost effective. Conclusion: The cost of CHD prevention using statins depends on the guidelines used. The ESC guidelines appear to yield the lowest costs per year of life gained free of CHD.

Talking about sexuality with the physician: are patients receiving what they wish?

QUESTIONS UNDER STUDY/PRINCIPLES: Little is known concerning patients' expectations regarding sexual history taking by doctors: to ascertain expectations and actual experience of talking about sexuality among male patients attending outpatient clinics, and their sexual behaviour. METHODS: Patients consecutively recruited from two outpatient clinics in Lausanne, Switzerland were provided with an anonymous self-administered questionnaire. Survey topics were: patients' expectations concerning sexual history taking, patients' lifetime experience of sexual history taking, and patients' sexual behaviour. RESULTS: The response rate was 53.0% (N = 1452). Among respondents, 90.9% would like their physician to ask them questions regarding their sexual history in order to receive advice on prevention (60.0% yes, 30.9% rather yes). Fifteen percent would be embarrassed or rather embarrassed if asked such questions. Nevertheless, 76.2% of these individuals would like their physician to do so. Despite these wishes, only 40.5% reported ever having a discussion "on their sexual life in general" with a doctor. Only one patient out of four to five was asked about previous sexually transmitted infections (STIs), the number of sexual partners and their sexual orientation. No feature of their sexual life distinguishes those who had discussed sexual issues with a doctor from those who had not, except a history of previous consultation for health problems related to sexuality. Conversely, being embarrassed about conducting this discussion was significantly associated with lack of discussion regarding sexuality. CONCLUSIONS: This study highlights the gap existing in the field of STI prevention in terms of doctors' advice and patients' wishes.
