Selected AbstractsEvaluation of a Prediction Model for Long-Term Fracture Risk,JOURNAL OF BONE AND MINERAL RESEARCH, Issue 4 2005L Joseph Melton III MD Abstract The NOF cost-effectiveness model, based on clinical risk factors and femoral neck aBMD, predicted overall fracture risk in a cohort of postmenopausal women followed for up to 22 years. Introduction: To assess the ability of a statistical model to predict long-term fracture risk for a population of postmenopausal women, we compared observed fractures to those predicted by the National Osteoporosis Foundation's (NOF) cost-effectiveness model. Materials and Methods: In this population-based study, 393 postmenopausal Rochester, MN, women had baseline measurements of femoral neck areal BMD (aBMD) and assessment of the clinical risk factors (personal fracture history, family history of osteoporotic fracture, low body weight, and smoking status) that were included in the NOF model. They were then followed prospectively for up to 22 years. Fractures were ascertained by periodic interview and review of community medical records. Standardized incidence ratios (SIRs) compared observed fractures to predicted numbers. Results: During 4782 person-years of follow-up, 212 women experienced 503 fractures, two-thirds of which were caused by moderate trauma. When undiagnosed (incidentally noted) vertebral and rib fractures were excluded, there was general concordance between observed and predicted fractures of the hip (SIR, 0.78; 95% CI, 0.56-1.01), distal forearm (SIR, 1.22; 95% CI, 0.86-1.68), spine (SIR, 0.76; 95% CI, 0.50-1.11), and all other sites combined (SIR, 1.18; 95% CI, 0.97-1.42). Fracture prediction by the NOF model was about as good after 10 years as it was earlier during follow-up. Conclusions: This study validates the ability of a statistical model based on femoral neck aBMD and common clinical risk factors to predict the actual occurrence of fractures in a cohort of postmenopausal white women.

The therapy is associated with various non-haematological negative side-effects, frequently involving the skin. Objective Our aim was to evaluate the actual occurrence of adverse skin reactions to HDAC over the 10-year period from 1989 to 1999. Methods One hundred and seventy-two subjects, 118 with acute myelogenous leukaemia and 54 with acute lymphoblastic leukaemia, between 16 and 71 years of age were treated with 226 post-remission consolidation regimens with HDAC (54 subjects underwent two cycles of treatment). Treatment was combined with standard doses of other cytotoxic drugs. A prospective study of the skin changes was then performed. Results The overall incidence of cutaneous reactions was almost 53%, with rashes occurring in 72.7% and 40.6% of subjects who received total doses of 30 and 24 g/m2, respectively. In the group of subjects who received a second cycle of treatment not all of those who experienced exanthema after the first cycle (44.4%) experienced this reaction after the second cycle (only 33.3%). The most commonly observed reactions were morbilliform eruptions on the trunk and extremities and acral erythema, although severe reactions with swelling and generalized urticaria developed in some cases. Conclusions HDAC-induced cutaneous reactions in 53% of subjects. The skin changes were found to be dose related and most cleared spontaneously without requiring treatment. A clinical grading of cutaneous toxicity has been proposed to allow better comparison of cutaneous adverse effects in different reports. [source] Challenges in Establishing the Epidemiology of Adverse Events Associated with Interventional Therapies for Chronic PainPAIN MEDICINE, Issue S1 2008Timothy R. Deer MD ABSTRACT Objectives., This paper aims to examine the current state of knowledge about adverse events associated with interventional pain techniques. Methods., This paper reviews the available databases on risk from sources such as closed claim analysis, peer review, and published literature; and also examines risk stratification for pain practitioners, the current state of malpractice insurance, and the procedures that are considered to have elevated risk. Conclusions., Substantial neurological sequelae can occur from interventional pain techniques. Considering the growing number of physicians who perform these procedures the actual occurrence of these problems appears to be low. The incidences of complications are difficult to correctly identify based on limitations of reporting and data analysis. The author recommends a national data bank be created to allow better monitoring and self assessment of the specialty of pain medicine. This information could be used to improve outcomes, reduce risk, and change clinical practice.

Van Driel PhD ABSTRACT Introduction., As specialists in male genital problems, urologists and sexologists will most likely to be involved in the treatment of males presenting with sleep-related painful erections (SRPEs). This means that this phenomenon needs to be recognized by urologists and sexologists, and that they should have knowledge of the current diagnostic and therapeutic approaches. Aim., To review the literature on SRPE and to find the best pharmacological treatment. Methods., Four personal clinical observations from two clinics and 29 other cases with SRPE found in PubMed were analyzed, especially regarding the results of pharmacological treatment. Main Outcome Measures., The results of pharmacological treatment. Results., Many of the various treatments proved to be ineffective and only a few showed efficacy for a few weeks or months. The only effective drugs in the long term were baclofen, clonazepam, and clozapine. Conclusions., Until now, the phenomenon of SRPE is not well understood. The rarity of the published cases undoubtedly does not reflect the actual occurrence of SRPE. Controlled double-blind pharmacological trials are needed, and long-term follow-up including polysomnography coupled with nocturnal penile tumescence and rigidity monitoring may provide further information about SRPE. van Driel MF, Beck JJ, Elzevier HW, van der Hoeven JH, and Nijman JM.

[source] The National Emergency Department Safety Study: Study Rationale and DesignACADEMIC EMERGENCY MEDICINE, Issue 12 2007Ashley F. Sullivan MS The significance of medical errors is widely appreciated. Given the frequency and significance of errors in medicine, it is important to learn how to reduce their frequency; however, the identification of factors that increase the likelihood of errors poses a considerable challenge. The National Emergency Department Safety Study (NEDSS) sought to characterize organizational- and clinician-associated factors related to the likelihood of errors occurring in emergency departments (EDs). NEDSS was a large multicenter study coordinated by the Emergency Medicine Network (EMNet; www.emnet-usa.org). It was designed to determine if reports by ED personnel about safety processes are significantly correlated with the actual occurrence of errors in EDs. If so, staff reports can be used to accurately identify processes for safety improvements. Staff perceptions were assessed with a survey, while errors were assessed through chart review of three conditions: acute myocardial infarction, acute asthma, and reductions of dislocations under procedural sedation. NEDSS also examined the characteristics of EDs associated with the occurrence of errors. NEDSS is the first comprehensive national study of the frequency and types of medical errors in EDs. This article describes the methods used to develop and implement the study. [source] Students' and teachers' perceived and actual verbal interactions in seminar groupsMEDICAL EDUCATION, Issue 4 2009A Debbie C Jaarsma Objectives, This study set out to examine how much time students and teachers devote to different learning-oriented interactions during seminar sessions and students' and teachers' perceptions about the occurrence and desirability of these interactions. Methods, Students and teachers participating in eight seminar group sessions in Year 4 of an undergraduate veterinary curriculum completed an 11-item questionnaire which asked them to rate, on a 5-point Likert scale, the frequency of occurrence and level of desirability of three learning-oriented types of interaction: exploratory questioning; cumulative reasoning, and handling of conflict about knowledge. The questionnaire also invited positive and negative responses to aspects of group interactions and an overall mark (1,10) for the seminars and group interactions. Four group sessions were video-recorded and analysed using a coding scheme. The amount of time devoted to the different interactions was calculated. Results, Both students and teachers gave scores of 3.0,3.5 for frequency of occurrence of exploratory questioning and cumulative reasoning and < 3.0 for occurrence of handling of conflict about knowledge. The desired occurrences of all interaction types were significantly higher than the actual occurrences according to students and teachers. Teachers were responsible for the majority of the interactions (93%). The percentages of session time devoted to teacher-centred cumulative reasoning, exploratory questioning and handling of conflict about knowledge were 65.8%, 15.6% and 3.1%, respectively. Conclusions, Group interactions in seminar groups are dominated by the posing of questions by teachers to students. The moderate occurrence of group interactions as perceived by students and teachers may be explained by the inadequate preparation of teachers and students to stimulate group interactions.
