The World Federation of Societies of Biological Psychiatry (WFSBP) Guidelines for the biological treatment of paraphilias

Abstract

Objectives. The primary aim of these guidelines was to evaluate the role of pharmacological agents in the treatment and management of paraphilia, with a focus on the treatment of adults males. Because such treatments are not delivered in isolation, the role of specific psychosocial and psychotherapeutic interventions was also briefly covered. These guidelines are intended for use in clinical practice by clinicians who diagnose and treat patients with paraphilia. The aim of these guidelines is to improve the quality of care and to aid physicians in clinical decisions. Methods. The aim of these guidelines was to bring together different views on the appropriate treatment of paraphilias from experts representing different continents. To achieve this aim, an extensive literature search was conducted using the English language literature indexed on MEDLINE/PubMed (1990–2009 for SSRIs) (1969–2009 for antiandrogen treatments), supplemented by other sources, including published reviews. Results. Each treatment recommendation was evaluated and discussed with respect to the strength of evidence for its efficacy, safety, tolerability and feasibility. Conclusions. An algorithm was proposed with six levels of treatment for different categories of paraphilias.     

我国成人体重指数和腰围对相关疾病危险因素异常的预测价值:适宜体重指数和腰围切点的研究

目的：确定我国成人适宜的体重指数（BMI）范围和超重肥胖的划分界限。国际生命科学学会中国办事处中国肥胖问题工作组，对国内现有体量指标和相关疾病危险因素的研究数据组织了汇总分析。方法：有13项1990年以后的调查资料人选，共计20－70岁以上成人23972人，有腰围数据者111411人，有血脂和血糖化验数据者8万余人。数据进入分析的人群分布于大陆21个省市、自治区儿台湾。汇总方法是由各负责单位根据统一制定的表格和标准提供数据，汇总分析中心进行核对、汇总和统计分析。结果；高血压、糖尿病、血清总胆固醇升高、高密度脂蛋白胆固醇过低、甘油三酯升高和危险因素聚集（一个人具有2个及以上危险因素）的现患率均随BMI或腰围的增高而上升。通过不同BMI和腰围切点对于检出各项危险因素异常的敏感度和特异度分析，提出敏感度特异度较好、假阳性率较低的BMI切24为中国成人超重的界限，特异度达90％的BMI切点28为肥胖的界限；男性腰围≥85cm，女性≥80cm为腹部脂肪蓄积的界限。结论：切点以上的人群归因危险度百分比显示：将BMI控制到24以下，可能防止人群中45％－50％的危险因素聚集。对BMI在28及以上者药物控制到此点以下，可能防止15％－17％的危险因素聚集，从而降低心血管病和糖尿病的发病危险。男性腰围控制在85cm以下，女性腰围控制到80cm以下， 可能防止约47％－58％的解除因素聚集。根据以上分析结果，提出了对中国成人超重和肥胖界限的建议。     

Detection of two distinct malignant B cell clones in a single patient using anti-idiotype monoclonal antibodies and immunoglobulin gene rearrangement

Immunoglobulin gene rearrangement analysis and somatic cell hybridization techniques were used to examine the malignant cell population in an unusual patient with hairy cell leukemia and macroglobulinemia (N Engl J Med 296:92, 1977). Although previous investigations suggested that the IgM macroglobulin was secreted by the circulating leukemia cells, anti-idiotype monoclonal antibodies raised to the IgM macroglobulin failed to react with the malignant cells in the circulation and bone marrow. In contrast, approximately 50% of the mononuclear cells from an enlarged inguinal lymph node reacted strongly with the anti-idiotype antibodies. Subsequent reanalysis of all cell populations demonstrated that whereas the circulating and bone marrow cells were IgM kappa-bearing, the macroglobulin was IgM gamma-bearing and the lymph node cells were evenly divided among IgM kappa-bearing and IgM gamma-bearing. Immunofluorescence flow cytometry indicated that those lymph node cells that reacted strictly with the anti-idiotype antibody were IgM gamma-bearing, demonstrating that they were the source of macroglobulin. An analysis of immunoglobulin gene DNA confirmed the coexistence of two distinct malignant B cell populations in the lymph node and indicated that the IgM kappa-bearing lymph node cells were identical to the circulating and bone marrow leukemic cells.     

Sports-related muscle injuries: evaluation with MR imaging

Sports-related muscle pain is frequent in both trained and untrained persons; however, its severity and significance may be difficult to assess clinically. The authors used magnetic resonance (MR) imaging to evaluate acute strains and delayed-onset muscle soreness in sedentary subjects and postmarathon myalgia in trained runners. MR imaging documented the distribution of affected muscles and the absence of focal hematoma, fascial herniation, subsequent fibrosis, and fatty infiltration. Pain associated with strain and that occurring several days after exercise were both associated with prolongation of muscle T1 and T2. In a prospective evaluation of delayed-onset muscle soreness, abnormalities depicted at MR imaging persisted longer than symptoms by up to 3 weeks, indicating that MR imaging is sensitive to tissue alteration that is not apparent clinically. Highly trained marathon runners tended to have relatively mild abnormalities involving the myotendinous junctions.
