Work-related laryngeal cancer: Trends in France from 2001 to 2016

Objectives

As part of the 2014–2019 cancer plan and in order to improve our knowledge of work-related cancers, we analysed the work-related laryngeal cancer risk situations identified in the French national occupational disease surveillance and prevention network (rnv3p) from 2001 to 2016.

必扑杀蟑饵剂连锁灭蟑效果观察

目的 观察连锁杀蟑饵剂在不同条件下的连锁灭蟑效果，并探讨其应用前景。方法 参照国标测试饵剂药效方法。利用试虫的“有毒”粪便、“有毒”虫尸，作为下一步实验试虫的食物，分别测试若虫、成虫的连锁实验，并测试有、无外源食物竞争情况下的连锁作用。结果 必扑杀蟑饵剂药效达到国标B级标准，在无外源食物竞争情况下，对若虫、成虫显示出良好连续杀灭效果，但若有外源食物竞争，则这一效果明显下降。结论 连锁杀蟑饵剂有连锁灭蟑效果。     

Comparative effects of luminance and scatter on the pattern visual evoked potential and eye-hand reaction time

We investigated the effect of reduced luminance and increased scatter on the pattern visual evoked potential and eye-hand reaction time evoked to a check size of 0.5° in 10 normal subjects. Data analysis indicated that a reduction in luminance as well as an increase in scatter caused a statistically significant increase in the peak time of the pattern visual evoked potential P₁₀₀ wave. The reaction time, however, was not significantly affected by the initial 0.9-log unit attenuation of the stimulus luminance or the 0.3 scatter filter. Further attenuation of luminance or increase of scatter also yielded statistically significant increases. Our results suggest that the reaction time is less affected by a reduction in luminance or an increase in scatter of a 0.5° stimulus than the pattern visual evoked potential is and therefore represents a more reliable test to assess visual function, especially in the presence of medial opacities, which are known to reduce luminance and produce scatter.     

影响老年髋部骨折手术治疗效果的因素分析

目的　探讨影响老年髋部骨折手术治疗效果的因素。方法　回顾性分析我院 1998年 1月～ 2 0 0 2年 1月 187例确诊为老年髋部骨折患者的临床资料 ,分析各种因素对手术治疗结果的影响。结果　患者年龄、伤前基本生活能力 (ADL)、行走能力、术前健康状况的美国麻醉学会 (ASA)分级、术后并发症等对治疗结果有明显影响 (P <0 .0 5 ) ;而性别、骨折类型、手术时间、手术方法等无明显影响 (P >0 .0 5 )。结论　术前ASA分级可很好预示老年髋部骨折术后死亡率 ,伤前ADL是影响术后功能康复的最主要因素。     

导致当前医患关系紧张的"五位一体"模式

医患关系紧张是当前医疗界面临的重要问题，经综合分析，这一问题主要由医院、医务人员、患者、医学院以及社会5大方面因素导致产生，并且各因素之间相互影响，相互制约，笔者称之为形成医患关系紧张的“五位一体”模式。     

Demographics of canine immune-mediated haemolytic anaemia in the Southeastern United States

Detailed examination of the records of 57 dogs referred to our clinic with the diagnosis of immunemediated haemolytic anaemia was accomplished. Only untreated dogs or dogs who had only received supportive therapy were included in the study group comprising 30 male dogs and 27 female dogs. Age distribution followed the general age distribution of our patient population. There was no within-breed sex or age predilection. The youngest dog was 11 months of age and the oldest dog was 13 years of age. Overall mortality rate among the study population was 51% (29 dogs). Certain canine breeds were over-represented in this study and these same breeds had high mortality rates. Included were 11 cocker spaniels (19%; 82% mortality rate, 9 of 11 dogs), nine dogs with terrier in their name (16%; 78% mortality rate, 7 of 9 dogs), six German shepherds (11%; 50% mortality rate, 3 of 6 dogs), five doberman pinschers (9%; 60% mortality rate, 3 of 5 dogs), and five miniature schnauzers (9%; 60% mortality rate, 3 of 5 dogs). Immune-mediated haemolytic anaemia was considered secondary to hepatic disease in 16 dogs (28%), septicaemia in 10 dogs (18%) and neoplasia in six dogs (11%), i.e. signs and data supporting these processes were reported to have preceded anaemia. A total of 29 dogs (51%) also had thrombocytopenia (platelet counts less than 60000 cells/µl), eight (14%) dogs had major venous thrombosis, eight (14%) dogs had associated disseminated intravascular coagulation, and 24 (42%) of the dogs had evidence of renal disease — proteinuria and cylinduria. About 35% (20 dogs) of the patients were treated from June to August, and 63% (36 dogs) of the patients were direct antiglobulin positive (immunoglobulin G with or without complement). A variety of red cell morphological changes were observed including stomatocytes, bowl forms, knizocytes, schistocytes and spherocytes. Spherocytes were observed in 11 dogs (19%). Absolute reticulocytosis was observed in 26 dogs (46%). A variety of treatment combinations including glucocorticoids, azathioprine, cyclophosphamide, anabolic steroids, heparin, intravenous human gamma globulin, and blood component therapy were used without identifiable success associated with any given protocol.

泰安市疾病监测点死因资料减寿年数(PYLL)分析

应用EYLL指标分析了泰安市疾病监测点1985、1986两年的死因资料,并计算了男、女居民两年的平均期望寿命,PYLL下降与期望寿命提高相一致。通过PYLL指标与其它死亡指标的比较,笔者认为PYLL指标来强调各种死亡原因引起居民“早死”造成寿命减少这一点上,优于其它指标。PYLL可作为评价居民健康水平较好的定量指标。
