Thirty-three patients with primary gastrointestinal lymphoma (GIL) followed at Ankara University Medical School have been evaluated. The most frequent locations of the disease are the small intestine (48.4%) and the stomach (39.3%). The intermediate and high grade lymphomas constitute 84.8% of the cases. The mean age of the patients with small intestinal lymphoma is 28.7 years and 47.1 years for those with gastric lymphoma. The patients treated with surgery and chemotherapy (S+CT) have a longer survival than those treated with chemotherapy (CT) alone. In conclusion: 1) Small intestinal lymphoma occurs more frequently than gastric lymphoma in our study. 2) The median age of the Turkish patients with primary GIL is approximately 10 years less than those in the Western countries. 3) The therapeutic results of S+CT are superior to those of CT in the early stages of the disease.  相似文献

In advance of a recruitment campaign, Israeli first-year nursing students of all ethnicities were surveyed to elucidate what factors had influenced them to make nursing their career and what sort of training track they preferred. The responses made it clear that different factors influence different groups differently. There were noticeable differences by gender, age, and ethnicity. Overall, training institutions were chosen for their closeness to the student's home but other factors also operated among particular groups, such as institutional prestige and flexible entry criteria. There was a blatant preference for academic, particularly university-sited, programs over diploma programs.  相似文献

OBJECTIVE: To determine whether racial differences in response to blockade of beta receptors occur among racial groups in Malaysia that are the Malays, Indians and Chinese. SUBJECTS, MATERIALS AND METHOD: 35 healthy male volunteers representing the 3 main racial groups in Malaysia (12 Malays, 12 Chinese and 11 Indians) were studied in a randomized, placebo-controlled, crossover and single-blind design. Propranolol 80 mg 12-hourly was given orally for 48 hours. Six hours after the last dose subjects attended an exercise session where resting and exercise heart rate, blood pressure, plasma potassium and glucose levels, resting FEV1 and plasma propranolol concentrations were recorded. RESULTS: No significant difference in plasma propranolol (mean +/- SEM) levels was seen between races six hours after the last dose (Malays, 59.7 +/- 8.8 ng/ml, Indians, 67.6 +/- 19.3 ng/ml, Chinese, 58.4 +/- 7.9 ng/ml). Chinese were least sensitive to the bradycardic and hypotensive effects of propranolol at rest and exercise. Indians and Malays had significant reduction of supine systolic blood pressure with propranolol but not Chinese. Comparison of percentage reductions of systolic blood pressure at supine, sitting and exercise by repeated measure analysis showed the Malays to have significantly higher change compared to the Chinese (p = 0.022). Similarly, comparison of percentage reductions of heart rate at supine, sitting and exercise by repeated measure analysis showed the Malays to have significantly higher change compared to the Chinese (p = 0.040). Average change in potassium concentrations at peak exercise and recovery showed the Indians to have significantly higher increase in potassium levels with propranolol compared to the Malays (p = 0.038). However, no significant interethnic difference was seen in the reduction of glucose levels at rest, peak exercise or recovery. Also, no significant interethnic difference was seen in reduction of FEV1 values. CONCLUSION: We, therefore, conclude that ethnic differences in response to blockade of beta-receptors exist among racial groups in Malaysia. These differences were seen at similar plasma drug levels between races suggesting ethnic differences in drug sensitivity, rather than differences in drug disposition.  相似文献

Police investigating a theft from a chocolate factory recovered three pieces of chocolate with irregular fractured surfaces displaying a pattern of marks made by human teeth. A highly accuracy dental impression material was used to prepare casts of these marks which were examined and photomicrographed, confirming that they had in fact been produced by human teeth. Casts and photomicrographs of the suspect's teeth were made in order to record the fine details of the casts of the dentition. Unique characteristics evident on these casts included a small notch on the incisal edge of the upper right lateral incisor, wear facets on the incisal edges of the upper central incisors and on the lower right lateral incisor and a space of approximately 1.5 mm between the upper left central incisor and lateral incisor which was rotated about 20 degrees distally. Both direct and photomicrographic comparisons between the casts of the chocolates and of the suspect's dentition revealed correspondence between their unique characteristics.  相似文献

Papillary fibroelastoma is a rare primary tumor of the heart valves. This lesion can occur on any of the valves or endothelial surface of the heart and has been detected by echocardiography, by cardiac catheterization, during open heart operations for other conditions, and at autopsy. Because of the potential for comorbidities, this tumor should be removed. We present the case of an elderly man with a diagnosis of severe mitral valve regurgitation and moderate tricuspid valve regurgitation who was suspected to have a tricuspid valve vegetation. Mitral valve replacement, tricuspid valve repair, and excision of the lesion were performed successfully. A histologic examination of the vegetation confirmed it to be a papillary fibroelastoma. We present this case to emphasize the rarity of this tumor and the importance of a correct diagnosis to avoid delaying its prompt and definitive management.  相似文献

This article further explores the effects of stress on leukocyte adhesiveness. The concentration of plasma catecholamines as well as the LAA values were examined in 16 volunteers during a cold pressor test and in 15 volunteers following physical activity. A significant correlation between LAA values and plasma norepinephrine, dopamine and epinephrine was noted. In addition, experimental studies of anaesthetized dogs infused with dopamine and norepinephrine showed increased LAA values, and an insulin-induced hypoglycaemic animal model for adrenergic stress indicated an inverse correlation between serum glucose concentrations and LAA values. Finally, in the presence of an MAO inhibitor, norepinephrine significantly increased the state of LAA in vitro. Thus, there exists an association between adrenergic stress and the appearance of sticky leukocytes in the circulating pool. We assume that, at least in part, this stickiness results from a direct effect of the catecholamines on the adhesive properties of the cells. Other factors might be related to the decreased endothelial adhesiveness towards the white blood cells as well as the concomitant effect of other mediators released during stress. This study also supports our notion that the state of LAA in the peripheral blood can serve as a useful stress marker.  相似文献

Background

Given the severe shortage of nurses in geriatric care in Israel and the planned expansion of their role in the care of older people, the Israel Ministry of Health's Nursing Division decided to investigate the readiness of current students to work in geriatrics.

Objectives

To gather last-year student nurses’ views on geriatric nursing as a career choice and identify the factors behind those views.

Design

A cross-sectional questionnaire study was designed.

Settings and participants

486 students (70% of the total last-year student nurse population) across the whole range of study settings completed the questionnaire in 2011.

Methods

On the basis of extensive data collection from focus groups of student nurses and working geriatric nurses a structured, self-administered questionnaire was compiled. The researchers distributed and collected the questionnaire in the students’ classrooms.

Results

61% of the 486 respondents had no intention of working in geriatrics while 12% considered the prospect favourably. 27% of the respondents were prepared to consider geriatric nursing as a career choice only after advanced specialist training in that field. 69% said that the planned expansion of the powers of geriatric nurses would incline them more favourably to work in geriatrics.A relatively high proportion of those interested in working in geriatrics were men. The students’ appraisal of the content of their training programme and of the current state of geriatrics in Israel appeared not to influence career choice. Multiple regression analysis found that the factors most predictive of geriatric care as a career choice were a generally favourable attitude to older people, the expansion of nurse powers in the sector and previous experience in older people care. Studying on an academic programme as opposed to a diploma programme was a negative predictor.

Conclusions

The non-influence of training programme content/design is the key finding. The chief recruitment effort should be invested in making the domain of geriatric nursing more attractive to nurses by improving its pay structure and expanding the powers of geriatric nurses to the level of Clinical Nurse Specialist, which would provide an attractive promotion track.  相似文献
