影响肝外伤手术死亡的危险因素分析

目的分析影响肝外伤手术死亡的危险因素,探讨其临床意义。方法根据AAST和ISS标准,回顾性分析90例肝外伤手术病例,对影响手术死亡的危险因素进行单因素比较和Logistic回归分析。结果死亡15例,其中Ⅲ级2例、Ⅳ级4例、Ⅴ级9例,总体手术死亡率17%。Ⅳ~Ⅴ级肝外伤手术方式的单因素比较提示:清创性肝切除术的相对危险度是0.73;而规则性肝切除术、肝静脉或肝后下腔静脉修补术相对危险度分别是1.32、1.52。Logistic回归分析提示:ISS分会和术中失血量是影响手术死亡率的2个独立因素。结论ISS分值、术中失出血量和手术方式是影响肝外伤手术死亡的3个重要因素,娴熟的手术技能和合理的手术方式可以减少术中出血量和降低手术死亡率。     

癫痫患者执行功能损害特点及影响因素研究

目的分析癫痫患者执行功能损害的特点及相关影响因素。方法1999年1月～2006年4月在我院癫痫专病门诊就诊或长期随访的109例成年癫痫患者和75例正常对照者进行神经认知心理测验，包括语义流畅性试验、数字广度测验、数字符号测验、色词干扰测验和连线试验检查。结果癫痫患者组语义流畅性显著差于正常对照组，数字广度、数字符号亦显著低于正常对照组．癫痫组连线时间、Stroop试验反应时显著延长，Stroop试验错误数显著增加（P〈0．01）。颞叶癫痫患者数字广度低于额叶癫痫患者。多元线性回归显示：文化程度高、非颞叶癫痫对语义流畅性有保护作用：文化程度高、单一抗癫痫药物治疗、病程短、年龄大对数字广度有保护作用；病程短、文化程度高和颅内无病灶对数字符号有保护作用。结论癫痫患者在多项执行功能方面均存在损害．文化程度高的患者执行功能相对较好；颞叶癫痫患者语义流畅性差；病程、药物、年龄对数字广度有影响：病程、有无病灶对数字符号有影响。     

A nationwide survey of excessive daytime sleepiness in Parkinson's disease in France

To determine the prevalence of excessive daytime sleepiness (EDS) and that of dozing and sudden onset of sleep episodes (SOS) while driving in ambulatory patients with Parkinson's disease (PD) in France, a national sample of private and public neurologists was asked to recruit the first 10 consecutive nondemented PD patients. Each patient completed a questionnaire including the Epworth Sleepiness Scale (ESS) and the likelihood of dozing off and experiencing SOS episodes behind the wheel. Clinical and demographic data were collected. One thousand six hundred and twenty‐five patients with PD were included in the survey. Twenty‐nine percent of the patients suffered from EDS (ESS score ≥10) but only 0.8% declared a high chance of dozing while driving and 0.5% reported totally unpredictable SOS episodes while driving. Risk factors for EDS were male gender, reduced activity of daily living, and a high daily levodopa equivalent dosage. Risk factors for SOS episodes while driving were an ESS score ≥10, male gender, and low Hoehn and Yahr staging. EDS is common in ambulatory patients with PD and is a major risk factor for dozing and for SOS episodes behind the wheel in patients who drive. © 2007 Movement Disorder Society     

头发、血浆、红细胞中铅对评价职业性接触水平的作用

[目的]探讨发铅、血浆和红细胞中铅对评价职业性铅接触水平的作用。[方法]用原子吸收分光光度计测定接触铅组与不接触铅对照组工人的血浆、红细胞及发中铅、铁、铜、镁、钙含量，测量数据用SAS软件处理。[结果]用0．25mol／L的HCl处理发样，能有效去除发表面的铅污染。接触组与对照组血浆铅无显著差异，而红细胞铅、发铅差异显著，血中其他元素含量无显著差异。[结论]去除表面污染的发铅和红细胞铅可作为铅接触指标。血浆铅则无意义。

Prevalence of occupational allergy due to live fish bait

BACKGROUND: Larvae of insects and worms, used as live fish bait (LFB), are a common source of allergy in anglers and occupationally exposed workers, but the prevalence and predictors have not yet been investigated. OBJECTIVE: This study assessed the prevalence and associated factors of occupational allergy in workers exposed to LFB. METHODS: We assessed the prevalence of sensitization to LFB and work-related symptoms (WRS) in 76 workers occupationally exposed to it. All workers completed a case history questionnaire and underwent skin prick tests (SPT) for common aeroallergens and bluebottle (Calliphora vomitoria), bee moth (Galleria mellonella), mealworm (Tenebrio molitor), and gusano rojo (Cilecomadia moorei). Specific IgE were tested in 64 subjects. Two-thirds of the workers had a high level of LFB exposure. RESULTS: Sensitization to LFB was found in 24 workers (31.6%). Seven subjects (9.2%) reported WRS (asthma in 3, rhinoconjunctivitis in 5, and contact urticaria in 1), and 5 were positive for SPT and serum IgE to one or more LFB extracts. One was also exposed to LFB while fishing. Sensitization to LFB extracts and WRS were strongly associated (Odds Ratio = 6.6, P < 0.05). The 7 subjects with WRS had been exposed longer than asymptomatic subjects with positive skin tests to LFB (P < 0.05). No differences in sex, age, smoking habit, duration or level of exposure, and atopy were detected in symptomatic or in sensitized subjects, compared with normal workers. CONCLUSION: Sensitization to LFB and WRS are relatively frequent in occupationally exposed workers. No associated factors of occupational allergy to LFB could be detected.
