应用质粒分析探讨医院内细菌感染的流行病学特点

为探讨医院内细菌感染的流行病学特点，作者借助临床分离的６４株肺为克雷伯菌，４５株阴沟肠杆菌和６３株醋酸钙不动杆菌，进行质粒图谱分３种细菌分别有５８株，３５株和４１株含有质粒，且分别构成４６个，２１个和２３个质粒图谱型。结果表明：质粒分析为查明医院内细菌感染源和感染途径提供了较为直接，准确的客观依据，同时也看到了质粒分析的局限性。     

Aspects of imported malaria at a district general hospital in non-endemic Kuwait,Arabian Gulf

There is no indigenous mosquito-borne transmission of malaria in Kuwait. However, in a five year period at a district general hospital, the number of laboratory-diagnosed cases of malaria increased annually from 25 to 84, a rise of 336%. Except for two induced infections, all were imported, mainly from the Indian subcontinent. Plasmodium vivax was responsible for 87.29% of the cases; P. falciparum (12.05%), a mixed infection of P. vivax and P. falciparum (0.33%) and a case of P. ovale (0.33%) were also identified. Rapid preparation of acetone-fixed, Giemsa-stained thick blood films, a heightened awareness of the infection, examination of multiple samples of blood from patients and the general resurgence of malaria in endemic areas were some of the factors responsible for the high number of cases diagnosed. Most patients were young males and presented with clinical malaria due to P. vivax between May and October each year, an apparent seasonal peak. However, many were already resident in the country for a variable period. Patients with P. falciparum though, presented clinically within two weeks of arrival in the country. Parasite densities were calculated to monitor the progress of treatment and identify quickly any possible chloroquine-resistant P. falciparum strains. A policy of active prophylaxis is suggested to stem the tide of imported malaria.Corresponding author.     

FEASIBILITY OF CONDUCTING CARDIOVASCULAR OUTCOME RESEARCH IN AUSTRALIAN GENERAL PRACTICE: RESULTS FROM THE ANBP2 PILOT STUDY

1. The present study aimed to determine the feasibility of conducting a 5 year cardiovascular outcome trial of the treatment of 6000 elderly hypertensive patients in Australian general practices. 2. General practitioners (GPs) were invited to participate by mail and personal follow-up. Patient records were reviewed to identify subjects for a blood pressure (BP) screening programme. Blood pressure was measured on three occasions and eligible subjects were included if the average BP was 160 mmHg systolic or 90 mmHg diastolic if systolic BP was 140 mmHg. 3. Seven hundred and forty-one GPs were approached and 89 were enrolled in the study (12% of mail invites and 75% of those receiving a personal contact). In 16 practices where screening was completed, 82 000 records were reviewed to identify 4% patients eligible for screening. Twenty-two per cent of eligible subjects attended screening. Of 1938 subjects screened, 180 (9%) had BP 5=160/90 mmHg. Forty-seven percent of subjects (n = 916) were receiving antihypertensive therapy and 184 (20%) were withdrawn from therapy. One hundred and sixteen (63%) of these subjects had BP return to study entry levels within 6 weeks. Fifty-seven newly diagnosed and 81 previously treated subjects were randomized (7% of the screened population). 4. Based on the high participation rate of GPs, the response rate of patients to attend a BP screening programme and the 7% randomization to screening ratio for entry into the study, the ANBP2 pilot study has demonstrated that it is feasible to recruit subjects from Australian general practices to a cardiovascular outcome trial.     

标化比例死亡比分析在筛检恶性肿瘤高发人群中的应用

在筛检肿瘤高危险人群过程中,应用标化比例死亡比(SPMR)的分析方法,研究了两个工厂全肿瘤和肺癌的发生状况,并用标化死亡比(SMR)的方法验证SPMR的结论。结果表明,两种方法分析结果均一致性显示全肿瘤和肺癌在两工厂中的死亡率显著高于当地居民。由于SPMR分析资料极易获得,分析方法又较SMR简便易行,适用于基层实际工作中对各种疾病死亡状况进行病因学分析。

Cardiovascular collapse during anesthesia in a patient with preoperatively discontinued chronic MAO inhibitor therapy

We describe a patient in whom long-term monoamine oxidase (MAO) inhibitor therapy was discontinued 20 days before surgery with general anesthesia. This patient developed severe perioperative hypotension after administration of 10 mg of bupivacaine through an epidural catheter, which was corrected only after potent vasopressor therapy. We attribute this hemodynamic instability to attenuation of this patient's sympathetic tone based on several mechanisms: (1) residual effect of long-term administration of MAO inhibitor that caused a decrease in the number of β-adrenergic receptors (adrenergic subsensitivity due to receptor down-regulation), (2) recovered MAO activity causing effective degradation of sympathetic amines, and (3) combined attenuating effects of general and epidural anesthesia on sympathetic tone.     

The Future of Clinical Psychology: Board Certification

The present article presents the future of clinical psychology board certification. With the increasing specialization in the field of professional psychology and the generic nature of state licensure, clinical psychology as a specialty will develop into a specialty area in a similar fashion as have specialties in medicine. A brief history of board certification in professional psychology by the American Board of Professional Psychology is reviewed and the process of becoming board certified in either clinical psychology or clinical child and adolescent psychology is discussed.
