Context: The epidemic of heart failure has yet to be fully investigated , and d ata on incidence, survival, and sexspecific temporal trends in community-based populations are limited. Objective: To test the hypothesis that the incidence of heart failure has declined and survival after heart failure diagnosis has improved over time but that secular trends have diverged by sex. Design, setting, and Participants: Population-based cohort study using the resources of the Rochester Epidemiology Project conducted in Olmsted County , Minnesota. Patients were 4537 Olmsted County residents (57%women; mean sD>> a ge, 74 > years) with a diagnosis of heart failure between 1979 and 2000. Fram ingham criteria and clinical criteria were used to validate the diagnosis Main O utcome Measures: Incidence of heart failure and survival after heart failure dia gnosis. Results: The incidence of heart failure was higher among men (378/100000 persons; 95%confidence interval >, 361-395 for men; 289/100000 persons; 95 %CI, 277-300 for women) and did not change over time among men or women. After a mean follow-up of 4.2 years (range, 0-23.8 years), 3347 deaths occurred, in cluding 1930 among women and 1417 among men. survival after heart failure diagno sis was worse among men than women (relative risk, 1.33; 95%CI, 1.24-1.43) but overall improved over time (5-year age-adjusted survival, 43%in 1979-1984 v s 52%in 1996-2000, Pver, men and younger persons experienced larg er survival gains, contrasting with less or no improvement for women and elderly persons. Conclusion: In this community-based cohort, the incidence of heart fa ilure has not declined during 2 decades, but survival after onset of heart failu re has increased overall, with less improvement among women and elderly persons.

Goals: To study the association between tobacco exposure and post- operative clinical recurrence in Crohn’ s disease patients and quantify the time to clin ical relapse following surgical resection. Background: It is well accepted that cigarette smoking has a negative impact on postoperative course in Crohn’ s dis ease. However, the effect of smoking to hasten clinical recurrence has not been clearly delineated. study: We reviewed medical records of patients undergoing su rgical resection for medication- refractory disease within a 5- year period. P atients were followed for a period of 250 weeks. Outcomes were compared between smokers and nonsmokers and stratified by gender. Results: Fifty- nine patients were studied. sixty- nine percent of smokers versus 23% of nonsmokers had rec urrent symptoms (P = 0.02) by the end of the observation period. There was no di fference in the mean ages, gender, disease location, use of postoperative medica tions, or number of postoperative visits (P > 0.09). smoking was associated wit h an increased risk of clinical recurrence [odds ratio 2.96 (95% confidence in terval, CI 1.5- 5.6)]. The time to clinical relapse for smokers was 130 weeks v ersus 234 weeks in nonsmokers (Psion: smoking is associated with clinical recurrence of Crohn’ s disease, and the time to clinical recurrence in smokers is shorter. strategie s for smoking cessation are warranted.

The genital self- mutilation is not rare in women. Risk factors found in these cases are: mood disorders, food behavior anomalies and antecedents of sexual aggression. However, surgical repair is not done in emergency: we find no similar report to our clinical case describing an added up bilateral reduction nymphoplasty carried out in emergency after hemorrhagic genital self-mutilation. We discuss psychological risk factors, psychiatric diagnosis and optimal treatment, studied from medico-ethical point of view, for this surgical emergency.

世界核心医学期刊文摘(眼科学分册) 2006年第4期 38-39页

作者： Anderson O.A. Lee v. shafi s. 王文军 Central Eye service Central Middlesex Hospital Acton Lane Park Royal London NW10 7NS United Kingdom

Purpose of study: To present a model for the assessment, investigation, and management of an atypical outbreak of infectious endophthalmitis of indeterminate aetiology. Methods: A published statistical model was used to determine when the case-load constituted an outbreak. Intraocular surgery was discontinued and a multidisciplinary infection control team was formed aimed at identifying potential causative factors among the following categories: environment around theatre, preoperative preparation, intraoperative theatre practices, intraoperative surgical practices,postoperative practices, equipment maintenance guidelines, cleaning/sterilization practices, and microbiological screening. Results: Five cases of postoperative endophthalmitis developed following uncomplicated phacoemulsification cataract surgery by different surgeons over a 7-month period. Despite full investigation no single focus of infection could be determined. Four out of five cases were culture positive. Three grew streptococcus viridansof different strains. The fourth culture grew staphylococcus aureus. In the absence of a single causative factor, it was postulated the combined effect of multiple potential factors may have led to an increased bacterial load and subsequent infection rate. Improved practices were initiated including new cleaning protocols to combat the build-up of debris on phacoemulsification instruments. Cataract surgery was resumed with 3-monthly microbiological monitoring. There have been no further cases in the 12 months following the changes. Conclusion: Outbreaks of endophthalmitis typically present over a short time period and could often be attributed to a single infective cause. We present our experience of detecting and managing this cluster and recommend a “ground-up”multidisciplinary model to manage future outbreaks of this devastating condition.

世界核心医学期刊文摘（妇产科学分册） 2006年第11期2卷 13-14页

Objectives: The aim of this study was to compare wet mount, Giemsa stain, acridine orange fluorescent stain, cultivation and polymerase chain reaction (PCR)- based approaches to establish which method or combination of methods was most effective in the laboratory diagnosis of trichomoniasis. study design: Out of 200 investigated patients with various gynecological complaints, Trichomonas vaginalis infection was detected in 27 (13.5% ) by any of methods investigated. Among women with trichomonads, a typical clinical finding was presented in only nine. For analysis of sensitivity and specificity of the methods used, the receiver operating characteristic (ROC) curve concept with culture as a gold standard was applied. Results: Infection was diagnosed by wet mount in 14 (7.0% ) women, by Giemsa stain in 11 (5.5% ) and by acridine orange stain in 16 (8.0% ) women. In 21 (10.5% ) women, it was diagnosed by culture in Diamond’s medium, and in 22 (11.0% ) by PCR. For the initial diagnosis of trichomoniasis, wet preparation is the test that is widely available in most sTD clinics, but its sensitivity is poor (66.67% ). Giemsa stain shows a low sensitivity of 52.38% . Acridine orange shows reasonable sensitivity and specificity of 71.43% and 99.44% , respectively. The sensitivity and speci ficity of PCR (80.95% and 97.21% ) did not exceed that of culture. Conclusion: With regard to the fact that trichomoniasis can have an atypical or even asymptomatic course, in order to accurately diagnose this disease, microbiological investigation is necessary. Comparison of different methods showed that at least two techniques, such as culture and acridine orange staining, have the potential for better diagnosis of T. vaginalis infection. PCR detection of infection has been demonstrated to be highly specific and sensitive, but its availability and cost effectiveness are in question. PCR could provide an alternative for laboratory diagnosis of trichomoniasis by culture.

Based on a series of experiments under both ice-covered and free surface conditions, the present article discusses the role of flow velocity and critical shear Reynolds number for incipient motion of bed material. The influence of the resistance coefficients of both the underside of the ice cover and the channel bed on the location of the maximum velocity has been discussed. In addition, the impacts of ice and composite resistance coefficients on flow velocity for incipient motion of bed material have been assessed. The diagram describing the critical shear Reynolds number and the dimensionless shear stress for the incipient motion of sediment under ice covered conditions with different under cover resistance coefficient has been established. The effects of grain size on densimetric Froude number for incipient motion of bed material have been investigated. A relationship between the densimetric Froude number for incipient motion of bed material and the median grain size of bed material as well as the roughness coefficient of channel bed and roughness coefficient of ice cover has been established.

Objective: The purpose of this study was to determine the ability of uterine artery Doppler and placental ultrasound to identify adverse clinical outcomes attributable to severe placental dysfunction in women with second- trimester unexplained elevated maternal serum screening of alpha- fetoprotein and human chorionic gonadotropin. study design: Fifty singleton pregnancies with elevated alpha- fetoprotein (3.5 multiples of median [range 2.1 to 10.5]) and human chorionic gonadotropin (5.3 multiples of median [range 2.5 to 21.7]) and a normal fetal anatomical ultrasound were prospectively evaluated with placental ultrasound and uterine artery Doppler at referral between 19 and 23 weeks’ gestation. Results: Abnormalities in both placental ultrasound and uterine artery Doppler (n = 24) predicted preterm delivery less than 32 weeks from any cause (n = 24) (75% sensitivity, 75% positive predictive value; likelihood ratio positive 3.3 [1.6 to 6.8]), intrauterine fetal death (n = 12) (100% sensitivity, 50% positive predictive value; likelihood ratio positive 3.1 [2.0 to 5.0]), and intrauterine growth restriction with absent/reversed end- diastolic flow (n = 17) (sensitivity 94% , positive predictive value 67% , likelihood ratio positive 3.9 [2.0 to 6.2]) . Ischemic- thrombotic pathology was present in 88% of placentas examined (n = 32). Conclusion: Uterine artery Doppler and placental morphology identified most pregnancies with combined abnormal maternal serum screening destined to result in extremely premature delivery and/or perinatal death. Abnormal maternal serum screening reports could include a recommendation for placental ultrasound testing when no fetal explanation has been identified.
