精索静脉曲张患者精索静脉和外周血睾酮水平的对照研究

目的：探讨精索静脉血张患者血浆睾酮水平的变化及其机制。方法：对25例精索静脉曲张患者与22例腹股沟斜疝患者精索静脉和外周血睾酮水平进行对照研究。结果：精索静脉曲张组外周血睾酮浓度与腹股沟斜疝组无差别（P＞0．05），而精索静脉血睾酮浓度两组则有明显差异，精索静脉曲张组精索静脉血中睾酮浓度较腹股沟斜疝组低（P＜0．05）。结论：多种因素可影响外周血睾酮浓度，使其难以准确地反映睾丸分泌睾酮的实际水平，而精索静脉血中的睾酮浓度则能较为直接地反映睾丸的睾酮分泌能力。     

小儿烧伤致伤因素及院前急救统计分析

目的 了解小儿烧伤的致伤因素和院前急救现状。方法 对十年来两家医院收治的小儿烧伤1403例按年龄、原因、场所以及院前急救进行回顾性分析。结果 小儿烧伤以0～3岁居多（占57．09％）；热液烫伤比例大（占70．28％）；家庭为烧伤主要场所（占78．12％）；院前急救失误普通存在，其中创面处理不当、未建立有效静脉通道和人为原因延误治疗比例较大。结论 小儿烧伤有一定规律，院前急救应加以重视。     

Frequency, nature and determinants of pharmaceutical consultations provided in private by Dutch community pharmacists

OBJECTIVE: According to a report published by the federation of Dutch patients' associations, patients would like to see a pharmacist, who acts more as a personal adviser. This raised the question, how often Dutch community pharmacists have personal consultations with their patients in daily practice, on which factors this depends, and what kind of topics are discussed during these meetings. SETTING: Community pharmacies in the Netherlands. METHOD: A questionnaire was distributed among 800 randomly selected pharmacies. Questions were restricted to consultations characterized by one-to-one contact, drug therapy related content, and adequate privacy. These consultations were labelled as pharmaceutical consultations in private to distinguish them from other contacts between pharmacists and patients. MAIN OUTCOME MEASURE: Number, content, and character of consultations. RESULTS: 198 (24.8%) community pharmacies responded. The pharmacists provide an average of roughly 1.2 consultations in private per working day. The vast majority of respondents provided face-to-face and telephone consultations (94.4 and 91.9%, respectively), only a minority gave consultations by e-mail (30.8%). These consultations primarily dealt with topics related to medication safety. The mean overall time spent was 290 min per month. A relatively high frequency of personal consultations was significantly associated with the absolute number of full-time equivalent pharmacists in the pharmacy. CONCLUSION: The frequency of pharmaceutical consultations in private is low, but may be improved by reorganisation of the pharmacist's activities. The possibility of personal consultations by e-mail is not yet well-developed. Further research is needed to assess the patient's view of pharmaceutical consultations in private.     

38例视网膜母细胞瘤的临床和误诊分析

目的 探讨视网膜母细胞瘤（retinoblastoma，RB）的临床特征、病理分类和误诊原因，尽可能减少错误的临床诊治。方法 对我科于1999-2004年间收集的38例临床诊断为视网膜母细胞瘤（retinoblastoma，RB）的病例资料进行回顾性分析。结果在38例疑似病例中，34例病理诊断为视网膜母细胞瘤，4例为Coats病。结论掌握相关的影像学知识和综合分析疑难病例的临床资料将有助于视网膜母细胞瘤的正确诊断和处理。     

Are hospitals prepared to support newborn survival? – an evaluation of eight first‐referral level hospitals in Kenya*

Objective To assess the availability of resources that support the provision of basic neonatal care in eight first‐referral level (district) hospitals in Kenya. Methods We selected two hospitals each from four of Kenya’s eight provinces with the aim of representing the diversity of this part of the health system in Kenya. We created a checklist of 53 indicator items necessary for providing essential basic care to newborns and assessed their availability at each of the eight hospitals by direct observation, and then compared our observations with the opinions of health workers providing care to newborns on recent availability for some items, using a self‐administered structured questionnaire. Results The hospitals surveyed were often unable to maintain a safe hygienic environment for patients and health care workers; staffing was insufficient and sometimes poorly organised to support the provision of care; some key equipment, laboratory tests, drugs and consumables were not available while patient management guidelines were missing in all sites. Conclusion Hospitals appear relatively poorly prepared to fill their proposed role in ensuring newborn survival. More effective interventions are needed to improve them to meet the special needs of this at‐risk group.     

Needle electromyography

Physiologic assessment of diseases of the motor unit from the anterior horn cells to the muscles relies on a combination of needle electromyography (EMG) and nerve conduction studies (NCS). Both require a unique combination of knowledge of peripheral nervous system anatomy, physiology, pathophysiology, diseases, techniques, and electricity is necessary. Successful, high‐quality, reproducible EMG depends on the skills of a clinician in patient interaction during the physical insertion and movement of the needle while recording the electrical signals. These must be combined with the skill of analyzing electric signals recorded from muscle by auditory pattern recognition and semiquantitation. 10 , 52 This monograph reviews the techniques of needle EMG and waveform analysis and describes the types of EMG waveforms recorded during needle EMG. © 2009 Wiley Periodicals, Inc.

Mental health in the population approaching retirement age. Preliminary findings of the TURVA project

The present paper deals with a Finnish long-term prospective study, the objective of which is to shed light on adjustment to retirement and old age. In this phase, only the preliminary findings of the initial survey carried out in 1982 are available. For the purposes of the study, a random sample of 200 individuals was drawn from among Turku inhabitants born in 1920. Another sample, consisting of 189 persons of the same age, was drawn from rural municipalities in the neighborhood of Turku. An extensive structured psychosocial interview could be conducted with a total of 339 subjects. The research methods used included e.g. the 36-item version of Goldberg's General Health Questionnaire (GHQ). Relatively little mental disturbance was revealed in the interview, and no major differences occurred between the urban and the rural sample. Somewhat over one-third of both samples were probable psychiatric cases as defined according to the GHQ.     

血液透析动脉穿刺术临床研究

目的:研究动脉穿刺技术,提高1次穿刺成功率。方法:将166例急、慢性肾功能衷竭接受血液透析的患者,随机分为观察组84例和对照组82例。观察组用新的穿刺方法,即先在动脉(桡动脉或足背动脉)搏动最明显或最清晰处按一印记,然后进针,对照组用传统的穿刺方法穿刺。比较两组所需时间、1次成功率、血流量、针眼处渗血、疼痛程度以及并发症。结果:两组穿刺所需时间、血流量、针眼处渗血,均有统计学意义(P<0.01)。结论:观察组用新的穿刺方法,能明显提高1次穿刺成功率,缩短穿刺时间,减轻患者痛苦,减少并发症发生。
