One of the most frequently used systems to analyse doctor-patient communication is the Roter Interaction Analysis System (RIAS). However, it has mostly been applied and evaluated in primary care settings. Two studies are presented in which the psychometric properties of the RIAS are investigated in an oncological setting. In the first study (N = 25) the feasibility, inter-rater reliability and content validity of the RIAS was investigated. In the second study, we evaluated the discriminant validity of the RIAS. Results of the first study showed that coding of tapes was more time consuming than indicated by the Roter manual. The inter-rater reliability proved to be high for both physician communication (0.68-1) and patient communication (0.60-1). The content validity proved to be acceptable: all utterances could be classified. However, coding dilemmas regarding affective communication occurred. The RIAS provided no option to classify communication of a third person present. Some communication categories were never or rarely used. Results of the second study indicate that the RIAS was able to discriminate between communicative behaviors in oncological consultations (N = 60) and three different GP-samples (random-GP sample N = 329, hypertension sample N = 103, gynaecology sample N = 65). To conclude, the psychometric properties of the RIAS are satisfactory in an oncological setting. 相似文献

Immunohistochemistry was used to evaluate the effects of neonatal handling and aversive stimulation during the first 10 days of life on the number of corticotrophs in the anterior lobe of the pituitary of 11-day-old male Wistar rats. Since adult rats handled during infancy respond with reduced corticosterone secretion in response to stressors and with less behavior inhibition in novel environments, we assumed that neonatal stimulation could affect pituitary morphology during this critical period of cell differentiation. Three groups of animals were studied: intact (no manipulation, N = 5), handled (N = 5) and stimulated (submitted to 3 different aversive stimuli, N = 5). The percentage of ACTH-immunoreactive cells in the anterior lobe of the pituitary (number of ACTH-stained cells divided by total number of cells) was determined by examining three slices per pituitary in which a minimum of 200 cells were counted by two independent researchers. Although animals during the neonatal period are less reactive to stress-like stimulation in terms of ACTH and corticosterone secretion, results showed that the relative number of ACTH-stained cells of neonatal handled (0.25 +/- 0.01) and aversive stimulated (0.29 +/- 0.03) rats was not significantly different from intact (0.30 +/- 0.03) animals. Neonatal stimulation may have a differential effect on the various subpopulations of corticotroph cells in the anterior pituitary. 相似文献

The authors present their experience gained in the training of ophthalmologists at the Chair of Ocular Diseases of the Krasnoyarsk Medical Institute. In 1991 the interns, instead of traditional state examinations, maintained their diploma research, which was assessed as their skills and knowledge in the field of ocular diseases, social hygiene, and public health organization. The authors prove that such diploma research is an integral part of undergraduate training and one of the types of individual work at higher educational institutions, and enumerate the topics of diploma research. 相似文献

From March 1994 to September 1996, 39 patients underwent stenting of the unprotected left main coronary artery because of high surgical risk. Stenting appeared to improve clinical outcome, but there was a significant mortality rate at long-term follow-up. 相似文献

Two new antibiotics, hongoquercins A and B, were isolated from fermentation extracts of the unidentified fungus LL-23G227. In the optimum medium, titers of the A and B components reached approximately 2.1 g/liter and 0.02 g/liter, respectively. The optimum temperature for antibiotic production was approximately 22 degrees C. Growth was delayed at 15 degrees C but appeared to reach higher levels than was observed at 22 degrees C. Addition of dextrose to growth media increased hongoquercin B production. Hongoquercin A exhibited moderate activity against Gram-positive bacteria. Mechanistic studies conducted in an E. coli imp strain suggested membrane damage as the primary mode of bactericidal action. These compounds also lysed human red blood cells, suggesting a similar mode of action on eukaryotic cells. 相似文献

Propofol is a new, fast-acting intravenous (i.v.) anesthetic. Involuntary movements or epileptic seizures have occurred during or after propofol-induced anesthesia in approximately 50 reported cases; a third of the patients have had epilepsy. We report 5 patients with seizures in association with propofol anesthesia. A female epileptic patient developed severe status epilepticus; the other patients with short-lasting seizures had no previous epilepsy. Although propofol has been used in treatment of patients of status epilepticus, the risk of precipitation of epileptic seizures warrants consideration especially when planning anesthesia for epileptic patients. 相似文献

Clinical observations of 1365 children with the lymph nodes affection were summarized. The diagnosis verification was conducted using the broad arsenal of general clinical and special methods of investigation. In complicated situations the histochemical and immunogenetic methods were applied for the diagnosis. The structure and dynamics of children's morbidity with lymphadenopathies (LAP) was studied up, the age, sexual and seasonal peculiarities were systematized, the analysis of primary localizations and clinico-morphological comparisons was conducted. The basic thesises of the standardized approach were elaborated on the ground of the diagnostical and tactical mistakes results analysis. 相似文献
