Link between the ability to detect and manage emotional disorders: a study of general practitioner trainees.

Independent ratings were made of videotaped consultations involving six general practice vocational trainees, of whom three were poor identifiers and three were able identifiers of emotional illness. Taped consultations were selected so that each trainee was rated interviewing five patients with low general health questionnaire scores, and five patients with high scores. It was found that able identifiers of emotional illness were more likely than poor identifiers to offer patients information, advice and treatment relevant to their illness, and that they did so in a manner likely to maximize patient satisfaction and cooperation. This was true for both distressed and non-distressed patients. It is argued that both the ability to identify emotional disturbances and the ability to manage emotional illness are characteristics of a generally superior interview style. This may reflect a common variable: the possession of good communication skills.     

Preliminary analysis of a randomized comparison of 5-fluorouracil versus 5-fluorouracil and high-dose continuous-infusion folinic acid in disseminated colorectal cancer

In this study, 50 patients were randomly assigned to treatment with 5-fluorouracil (FUra) or FUra plus high-dose continuous-infusion folinic acid. Five of 27 evaluable patients in the FUra group versus 10 of 21 patients in the FUra plus folinic acid arm of the study had objective partial remissions, P = 0.02. Time to progression was 3.9 months for FUra and 8.0 months for FUra and folinic acid, P = 0.006; however, median survivals (11.9 versus 14.5 months) were not different in this crossover study. Toxicity in both treatment arms was mild, although patients receiving FUra plus folinic acid experienced significantly more stomatitis than patients treated with FUra alone. This study suggests that high-dose, continuous-infusion folinic acid, which produces a steady-state level of biologically active folates of 10 microM, significantly increases the therapeutic activity of FUra.     

Left atrial myxoma: diagnosis by digital subtraction intravenous angiography

Digital subtraction intravenous angiography (DSIVA) represents an important technical advance in angiographic diagnosis. Herein we present three patients with left atrial myxoma assessed by DSIVA. We review the role of DSIVA in evaluation of patients with suspected cardiac tumors and the importance of careful atrial-phase scrutiny in examinations obtained for other purposes (ie, pulmonary angiography and assessment of ventricular function).     

Longitudinal predictors of continued tobacco use among patients diagnosed with cancer

Even though continued smoking by cancer patients adversely affects survival and quality of life, about one third of patients who smoked prior to their diagnosis continue to smoke after their diagnosis. The implementation of smoking cessation treatments for cancer patients has been slowed by the lack of data on correlates of tobacco use in this population. Thus, this longitudinal study assessed demographic, medical, addiction, and psychological predictors of tobacco use among 74 head, neck, and lung cancer patients. Multivariable binary logistic regression analyses, with outcome categorized as smoker or nonsmoker, indicated that the likelihoodthat patients would be a smoker was associated with lower levels of perceived risk and a higher level of quitting cons. Multivariable nominal logistic regression, with outcome classified as continuous smoker, continuous quitter, relapser, or follow-up quitter, indicated that: (a) patients categorized as continuous smokers reported significantly lower quitting self-efficacy than follow-up quitters and continuous quitters, (b) relapsers reported a significantly lower level of quitting self-efficacy than either follow-up quitters or continuous quitters, and (c) continuous smokers exhibited a significantly lower level of risk perceptions than continuous abstainers. These findings can be useful for the development and evaluation of treatments to promote smoking cessation among cancer patients. Support for this study was provided by National Institutes of Health Grants CA57708, CA06927, CA88610, CA95678, and CA76644.     

无家可归者多地点结核病传播

地点：2002-2003年，在华盛顿King县，结核病（TB）在多个收容所的人群中大规模爆发。 目的：控制结核病在多个地点的传播。设计：2002年，对收容所病人的接触者进行筛查，作结核菌素皮试（TSTs）和症状回顾。根据这些筛查的结果，确定和优选传播的地点。2003年，对暴露于这些点的队列作彻底的筛查（例如，症状回顾，TST，胸部X线检查[CXR]，痰检和痰培养）。利用PCR为基础的方法对从病人那里分离出来的结核分枝杆菌作基因分型，以快速确认爆发相关病人。 结果：2002-2003年，King县313例确诊的病人中有48例（15％）与爆发相关；通过基因分型，47例培阳病人分离出和爆发相匹配的菌株。3个收容所由于在2002年接纳的病人超过12人，所以人群中TST阳性率（约30％）高于收容所中的一般水平（7％）。用一个痰培养筛查接触者和CXR发现结核病人的敏感度相似（分别为77％和62％）。 结论：一个广泛的资源密集的途径可能有助于控制疾病的传播。这次爆发突显出无家可归者的脆弱性和在城市维持强有力的结核病规划的必要性。     

The use of methotrexate in steroid-resistant systemic lupus erythematosus

Although the use of methotrexate (MTX) is gaining acceptance in the treatment of several connective tissue diseases, there is little evidence of its therapeutic value in systemic lupus erythematosus (SLE). We examined the response to MTX in patients with steroid-resistant SLE in an open, unblinded study. Of 10 SLE patients treated with MTX (7.5 mg/weekly), 7 showed improvement. The other 3 stopped therapy because of lack of response or because of side effects. Improvements were noted within 3 months in responding patients. These promising observations suggest that controlled studies of MTX for the treatment of SLE are justified.
