An easy and safe procedure for temporal artery biopsy.

BACKGROUND: Temporal arteritis is a very serious form of vasculitis. Early treatment is essential to avoid blindness. Surgical biopsy of the temporal artery is the gold standard for the diagnosis, but facial nerve injuries may occur. OBJECTIVE: To describe a simple and safe procedure for temporal artery biopsy. METHODS: Case report. RESULTS: A 62-year-old-woman with presumed temporal arteritis was referred. Precise localization of temporal arteries and its branches was obtained with color duplex ultrasonography. Arterial wall thickening (halo sign) was observed in the affected arterial segments. A frontal branch was precisely localized and infiltrated with 1% lidocaine. About 1 cm was removed for histopathologic examination. Thirty minutes was required to perform this outpatient procedure. The diagnosis of temporal arteritis was confirmed, and the patient was rapidly and successfully treated with prednisone. CONCLUSIONS: Color duplex ultrasonography allows precise localization of temporal arteries and its branches. This echocardiography-guided surgical procedure is easy and safe. Most dermatologic surgeons can perform it.

Implementation and evaluation of an internet health site for adolescents in Switzerland.

Ciao is a website specifically designed for young people and focuses mainly on health issues. This report presents the process of setting up the site and a first evaluation undertaken by using two self-administered questionnaires administered via the website itself. It suggests that it is possible to provide young people with authoritative health information and to facilitate their access to counseling and health care facilities by having young people use such a website.

Development of a Selective Peptide Macrocycle Inhibitor of Coagulation Factor XII toward the Generation of a Safe Antithrombotic Therapy.

Inhibition of coagulation factor XII (FXII) activity represents an attractive approach for the treatment and prevention of thrombotic diseases. The few existing FXII inhibitors suffer from low selectivity. Using phage display combined to rational design, we developed a potent inhibitor of FXII with more than 100-fold selectivity over related proteases. The highly selective peptide macrocycle is a promising candidate for the control of FXII activity in antithrombotic therapy and a valuable tool in hematology research.

A U-shaped association between intensity of Internet use and adolescent health.

OBJECTIVE: To examine the relationship between different Internet-use intensities and adolescent mental and somatic health. METHODS: Data were drawn from the 2002 Swiss Multicenter Adolescent Survey on Health, a nationally representative survey of adolescents aged 16 to 20 years in post-mandatory school. From a self-administered anonymous questionnaire, 3906 adolescent boys and 3305 girls were categorized into 4 groups according to their intensity of Internet use: heavy Internet users (HIUs; >2 hours/day), regular Internet users (RIUs; several days per week and <= 2 hours/day), occasional users (<= 1 hour/week), and non-Internet users (NIUs; no use in the previous month). Health factors examined were perceived health, depression, overweight, headaches and back pain, and insufficient sleep. RESULTS: In controlled multivariate analysis, using RIUs as a reference, HIUs of both genders were more likely to report higher depressive scores, whereas only male users were found at increased risk of overweight and female users at increased risk of insufficient sleep. Male NIUs and female NIUs and occasional users also were found at increased risk of higher depressive scores. Back-pain complaints were found predominantly among male NIUs. CONCLUSIONS: Our study provides evidence of a U-shaped relationship between intensity of Internet use and poorer mental health of adolescents. In addition, HIUs were confirmed at increased risk for somatic health problems. Thus, health professionals should be on the alert when caring for adolescents who report either heavy Internet use or very little/none. Also, they should consider regular Internet use as a normative behavior without major health consequence. Pediatrics 2011;127:e330-e335

Phthalates in the NICU: Is it safe?

AIMS: As growing concerns exist regarding phthalate exposure, which could be teratogenic, carcinogenic or induce reproductive toxicity, we aimed to review the evidence of the risks due to the use of medical devices containing di(2-ethylhexyl)phthalate in hospitalized neonates. METHODS: We reviewed the literature, searching through medical literature databases (Pubmed, MEDLINE, EBM reviews, Cochrane database, Embase and Google Scholar) using the following keywords: phthalate, di(2-ethylhexyl)phthalate, newborn and neonate. RESULTS: We identified several associations with short and long term health dangers, mainly subfertility, broncho-pulmonary dysplasia, necrotising enterocolitis, parenteral nutrition associated cholestasis and neuro-developmental disorders. These data are based mainly on animal or observational human studies. CONCLUSION: Clinicians must be aware of the potential risks due to phthalate exposure in the NICU. Di(2-ethylhexyl)phthalate containing materials should be identified and alternative devices should be considered. There is a need to improve knowledge in this area.

Internet use by patients with psychiatric disorders in search for general and medical informations

BACKGROUND: Internet is commonly used by the general population, notably for health information-seeking. There has been little research into its use by patients treated for a psychiatric disorder. AIM: To evaluate the use of internet by patients with psychiatric disorders in searching for general and medical information. METHODS: In 2007, 319 patients followed in a university hospital psychiatric out-patient clinic, completed a 28-items self-administered questionnaire. RESULTS: Two hundred patients surveyed were internet users. Most of them (68.5%) used internet in order to find health-related information. Only a small part of the patients knew and used criteria reflecting the quality of contents of the websites consulted. Knowledge of English and private Internet access were the factors significantly associated with the search of information on health on Internet. CONCLUSIONS: Internet is currently used by patients treated for psychiatric disorders, especially for medical seeking information.

High-dose daptomycin plus fosfomycin is safe and effective in treating methicillin-susceptible and methicillin-resistant Staphylococcus aureus endocarditis.

We describe 3 patients with left-sided staphylococcal endocarditis (1 with methicillin-susceptible Staphylococcus aureus [MSSA] prosthetic aortic valve endocarditis and 2 with methicillin-resistant S. aureus [MRSA] native-valve endocarditis) who were successfully treated with high-dose intravenous daptomycin (10 mg/kg/day) plus fosfomycin (2 g every 6 h) for 6 weeks. This combination was tested in vitro against 7 MSSA, 5 MRSA, and 2 intermediately glycopeptide-resistant S. aureus isolates and proved to be synergistic against 11 (79%) strains and bactericidal against 8 (57%) strains. This combination deserves further clinical study.

Home care: a safe and attractive alternative to inpatient administration of intensive chemotherapies.

OBJECTIVE: The objective of this study was to evaluate feasibility, safety, perception, and costs of home care for the administration of intensive chemotherapies. METHODS: Patients receiving sequential chemotherapy in an inpatient setting, living within 30 km of the hospital, and having a relative to care for them were offered home care treatment. Chemotherapy was administered by a portable, programmable pump via an implantable catheter. The main endpoints were safety, patient's quality of life [Functional Living Index-Cancer (FLIC)], satisfaction of patients and relatives, and costs. RESULTS: Two hundred days of home care were analysed, representing a total of 46 treatment cycles of intensive chemotherapy in 17 patients. Two cycles were complicated by technical problems that required hospitalisation for a total of 5 days. Three major medical complications (heart failure, angina pectoris, and major allergic reaction) could be managed at home. Grades 1 and 2 nausea and vomiting occurring in 36% of patients could be treated at home. FLIC scores remained constant throughout the study. All patients rated home care as very satisfactory or satisfactory. Patient benefits of home care included increased comfort and freedom. Relatives acknowledged better tolerance and less asthenia of the patient. Home care resulted in a 53% cost benefit compared to hospital treatment (420 ± 120/day vs. 896 ± 165/day). CONCLUSION: Administration of intensive chemotherapy regimens at home was feasible and safe. Quality of life was not affected; satisfaction of patients and relatives was very high. A psychosocial benefit was observed for patients and relatives. Furthermore, a cost-benefit of home care compared to hospital treatment was demonstrated.

Évaluation de la qualité des sites internet francophones traitant de la dépendance à l'alcool

L'objectif de cet article est d'investiguer de manière systématique la qualité des sites internet francophones traitant de la dépendance à l'alcool. Les auteurs ont examiné les 20 premières pages identifiées par trois moteurs de recherche généraux avec deux mots clés. Au total, 45 sites pertinents ont été évalués. Les auteurs concluent que la qualité globale des sites est relativement pauvre, spécialement pour la description des traitements possibles, et largement variable. La qualité de contenu n'est pas corrélée avec les autres aspects évalués tels que l'interactivité, l'esthétisme ou le dévoilement de l'identité des auteurs ou de leur source.

Evaluation Of "Safe" Trabeculectomy Versus "Safe" Phacotrabeculectomy

Purpose: To evaluate the safety and efficacy of "safe" trabeculectomy (ST) versus "safe" phacotrabeculectomy (SPT).Methods: This study included 72 eyes with medically uncontrolled chronic glaucoma who underwent fornix based trabeculectomy with adjustable/releasable sutures and intraoperative mitomycin C ± phacoemulsification. 36 eyes underwent SPT and 36 eyes had ST. There was no difference between groups for age, intraocular pressure (IOP), diagnosis and gender. Subconjunctival antimetabolite injections and bleb needlings were administered according to bleb vascularity and IOP trends. Main outcome measures were: success rate (definition: IOP≤21mmHg and 20% IOP reduction); number of antimetabolite injections; bleb needlings; glaucoma medications and complications.Results: Mean age (SPT vs ST) was 72.7±12.1 years vs 72.3±12.9 years; p=0.44. Mean preoperative IOP was 24.5±8.8 mmHg vs 24.3±8.2 mmHg; p=0.46. Postoperative IOP was 13.1±4.5mmHg vs 12.4±3.2; p=0.24. Ninety percent of both groups required at least one suture removal. There was no statistically significant difference in success rate between groups, 80% vs 83%; number of eyes requiring antimetabolite injections was 22 eyes (mean 3.2 per eye) vs 23 eyes (mean 2.6 per eye, p=0.24); bleb needlings was performed in 16 eyes (mean 2.5 per eye) vs in 11 eyes (mean 2.0 per eye, p=0.15). The number of eyes restarting glaucoma medications was 5 vs 4. Minor complications were infrequent in both groups, 9 vs 10 eyes.Conclusions: The success and complications rates were similar between groups. The number of postoperative interventions required was slightly greater in the SPT group (not statistically significant). SPT is a safe procedure for patients with coexistent glaucoma and cataract and produces similar IOP-lowering to safe trabeculectomy.

Almost routine prophylactic cholecystectomy during laparoscopic gastric bypass is safe

RAPPORT DE SYNTHESE : Introduction : les patients obèses morbides présentent un risque majeur de développer des calculs biliaires en raison d'une sécrétion accrue de cholestérol dans la bile. Ce risque, davantage élevé dans la phase de perte pondérale rapide consécutive à la chirurgie bariatrique ou lors de régimes amaigrissants, est souvent la cause de nombreux symptômes, voire de complications biliaires. Aussi l'association d'une cholécystectomie à la chirurgie bariatrique, notamment le bypass gastrique laparoscopique a-t-elle été proposée afin d'éviter ces complications parfois redoutables dans cette population fragile. Ce concept a cependant fait l'objet de démentis dans de récentes études où ce risque apparaîtrait moins élevé, et la cholécystectomie durant le by- pris gastrique laparoscopique pourrait être grevée de difficultés et présenter des risques opératoires non négligeables pour le patient. Patients et méthodes : notre série comporte 772 patients opérés entre 2000 et 2007 par by-pass gastrique laparoscopique, avec montage d'une anse en Y selon Roux. Ces patients obèses morbides avaient été sélectionnés sur la base d'une anamnèse concluante, d'un examen anthropométrique, d'un bilan sanguin et d'un ultrason abdominal. Une analyse rétrospective des résultats d'ultrason abdominal préopératoire et des rapports histopathologiques des vésicules biliaires en postopératoire a été réalisée chez les patients opérés avant 2004. Résultats : 58 patients (7,5 %) avaient déjà eu une cholécystectomie. L'US abdominal a révélé des calculs ou de la boue biliaire chez 81 patients (11,3 %), un polype chez un patient et une vésicule biliaire normale chez les patients restants. La cholécystectomie a été réalisée concomitamment au by-pass gastrique chez 66S patients (91,7 %) et des calculs biliaires retrouvés à l'examen per-opératoire des vésicules biliaires chez 25 patients (3,9 %), rapportant alors la prévalence de la cholélithiase à 21,2 % dans cette population. L'âge des patients porteurs de calculs biliaires était significativement plus élevé que celui des patients sans calculs biliares (43,5 contre 38,7 ans, P < 0,0001). A l'examen histopathologique, des anomalies ont été décrites dans 81,8 % des vésicules biliaires, consistant pour la plupart en cholécystite chronique et cholestérolose. Aucune complication post-opératoire n'a été associée à la cholécystectomie et le prolongement du temps opératoire était en moyenne de 19 minutes (4 - 45 minutes) sans aucun impact sur le séjour hospitalier. La cholécystectomie n'a pas été réalisée chez 59 patients (8,3 %) en raison de conditions opératoires défavorables, notamment une exposition insuffisante. Un traitement d'acide ursodésoxycholique a été prescrit sur une période de 6 mois et aucun de ces patients n'a manifesté de symptômes biliaires. Conclusion : la cholécystectomie peut être réalisée à titre prophylactique et en toute sécurité au cours du by-pass gastrique laparoscopique. Cet acte opératoire supplémentaire sans conséquence sur le séjour hospitalier, constitue selon la présente étude une forme de prophylaxie recommandable dans la prévention de la formation des calculs biliaires dans la phase de perte pondérale post-opératoire. Sa supériorité ou non par rapport à la prophylaxie médicamenteuse à l'acide ursodésoxycholique n'a pas encore été établie. Des études prospectives randomisées seraient nécessaires afin de confirmer l'avantage de l'une ou l'autre de ces deux alternatives.
