Alcohol consumption shows a U-shaped relation with all-cause and cardiovascular mortality. To determine whether a similar relation exists between alcohol and chronic obstructive pulmonary disease mortality, we analyzed data on alcohol consumption in 1970 and 20-year mortality from chronic obstructive pulmonary disease among 2,953 middle-aged men from Finland, Italy, and the Netherlands. We also studied alcohol consumption in relation to pulmonary function (FEV1 or FEV0.75) at baseline. We used regression models adjusted for age, height (for pulmonary function only), body mass index, smoking habits, energy intake, and country. A smoothed spline-plot showed a U-shaped relation between alcohol and chronic obstructive pulmonary disease mortality. Compared with non-drinkers and occasional drinkers, the relative risk of chronic obstructive pulmonary disease mortality was 0.60 (95% CI = 0.33-1.09) in light drinkers (> 1 drink per week, < or = 3 drinks per day) and 1.25 (95% CI = 0.47-3.31) in moderate-to-heavy drinkers. Pulmonary function was lower in non-drinkers compared with occasional and light drinkers in Finland (75 ml, 95% CI = -2 to 151) and the Netherlands (93 ml, 95% CI = 0-186) and lower in very heavy (> 12 drinks per day) compared with moderate-to-heavy drinkers in Italy (99 ml, 95% CI = 9-189). In conclusion, we observed a U-shaped curve between alcohol consumption and 20-year chronic obstructive pulmonary disease mortality in middle-aged men that was supported by cross-sectional data on alcohol and pulmonary function.  相似文献

Hydatid disease involving the vertebral body and paravertebral soft tissues is rare even in rural areas where echinococcosis is endemic. The case of a 34-year-old woman with vertebral hydatid disease mimicking tuberculous spondylodiscitis (Pott's disease) is presented in this report. Spinal hydatid disease should be considered in the differential diagnosis of spondylodiscitis in endemic countries, and tested for with imaging and serology.  相似文献

AIM: To examine the effects of 10% diluted honey, which has been shown to be scolicidal, on the liver and biliary system and determine whether it could be used as a scolicidal agent in the presence of biliary-cystic communication. METHODS: Thirty Wistar-Albino rats were divided into two groups. Honey with 10% dilution in the study group and 0.9% saline (NaCI) in the control group were injected into the common bile ducts of rats through a 3-mm duodenotomy. The animals were sacrificed 6 mo alter the procedure. Histopathological, biochemical, and radiological examinations were performed for evaluation of side effects. RESULTS: At the end of the sixth month, liver function tests were found to be normal in both groups. The tissue samples of liver and ductus choledochus of the honey group showed no histomorphologic difference from the control group. No stricture on the biliary tree was detected on the retrograde cholangiograms. CONCLUSION: According to these results, we concluded that 10% diluted honey could be used as scolicidal agent safely in the presence of biliary-cystic communication.  相似文献

Purpose

The Integrated Procedural Performance Instrument (IPPI) consists of clinical scenarios in which bench-top models are positioned to simulated patients. Trainees are required to perform technical skills while engaging with the patient. The purpose of this study was to determine whether an IPPI format examination could discriminate between different levels of trainees.

Methods

Sixteen fourth-year medical students and 16 first-year surgery residents participated in 4 IPPI scenarios. Videotaped performances were scored by 2 blinded independent clinician raters on previously validated instruments: checklist of technical skills, Global Rating Scale of technical skills, and communication scale. We conducted separate mixed design analyses of variance (level × cases) on the 3 scales.

Results

Residents performed better than medical students on the checklist (74% vs 60%, P < .05), the Global Rating Scale of technical skills (75% vs 56%, P < .01), and the coherence communication subscale (79% vs 69%, P < .05).

Conclusions

An IPPI examination discriminated between students' and residents' technical skills and coherence in communication skills. It also highlighted a potential gap in the training of residents' communication skills.  相似文献

OBJECTIVES: In this study, we investigated the clinical features, etiology, and also predictive factors of secondary erythema nodosum (EN) in patients with EN. METHODS: A total of 100 patients (mean age: 37 years) diagnosed with EN between 1993 and 2004 in our clinic were included in the study prospectively. A skin biopsy was performed in 46 of the patients. Patients were considered to have secondary EN when an underlying condition was found, and to have primary EN when no such condition was found. For the diagnosis of the underlying diseases, the pertinent diagnostic criteria and/or diagnostic methods were used. Categorical and continuous variables were compared by using chi-square and Mann-Whitney U tests respectively. Multiple regression analysis was applied to the significantly different variables. RESULTS: The majority of the patients were female (female/male: 6/1) and nearly half (47%) of the cases had a determined etiology. The leading etiology was poststreptococcal (11%), followed in decreasing order by primary tuberculosis (10%), sarcoidosis (10%), Beh?et's syndrome (BS) (6%), drugs (5%), inflammatory bowel diseases (IBD) (3%), and pregnancy (2%). Fifteen (15%) patients complained of cough; the diagnosis was primary tuberculosis in eight cases and sarcoidosis in seven. Four patients with arthritis were diagnosed as having BS (in 3) and Crohn's disease (in 1). All the patients were followed for a mean duration of 4.5 years. The nodosities relapsed annually in 62% (33/53) of idiopathic EN patients but in only one (BS) in the secondary EN group. The histology was consistent with EN in all biopsied patients. Our study revealed that fever, leukocytosis, elevated CRP level, accelerated ESR, presence of cough, sore throat, diarrhea, arthritis, and pulmonary pathology were predictors of secondary EN. Recurrence in EN significantly predicted primary EN. All of the patients had bed rest and the majority was given an anti-inflammatory agent (naproxen sodium). The outcomes were usually favorable within 7 days. The patients with an underlying disease were given the specific treatment. CONCLUSION: EN has been associated with numerous diseases. In order to reduce cost and duration of diagnosis, every centre should determine its own most frequent etiologic factors. Predictive variables for secondary EN should also be determined and an optimum management for such patients should be clarified. Our study revealed streptococcal pharyngitis, primary tuberculosis, sarcoidosis, IBD, and BS as the main etiologies of EN.  相似文献
