This study evaluates the effects of glucagon 30 mug/kg (maximal 1 mg) on beta-cell function in children by C-peptide determined before and 6 min after intravenous administration. From 1990 to 2005, 118 Taiwanese children with newly diagnosed diabetes mellitus (98 children with type 1 and 20 children with type 2) and 29 normal Taiwanese children were enrolled in this study. Fasting and 6-min post-glucagon C-peptide levels were analyzed. In the pre-pubertal group, the median fasting serum C-peptide levels were 0.2 and 0.8 nmol/l in type 1 diabetes and normal children, respectively. These levels rose to 0.3 and 1.9 nmol/l after glucagon stimulation. In the pubertal group, the median fasting serum C-peptide levels were 0.3, 1.0 and 0.9 nmol/l in type 1 diabetes, type 2 diabetes and normal children, respectively. They rose to 0.4, 2.5 and 2.7 nmol/l after glucagon stimulation. Both fasting and post-glucagon C-peptide levels in type 1 diabetes patients were significantly lower than those of normal children and children with type 2 diabetes. The optimal cut-off values to distinguish type 1 diabetes patients from those with type 2 as determined by the receiving operating characteristic curve were 0.7 and 1.1 nmol/l, respectively. The sensitivities of both C-peptide values were 93%. The post-glucagon C-peptide level was more powerful in distinguishing type 1 diabetes from type 2 diabetes with higher specificity (95% vs. 85%). The 6-min glucagon test is valuable in assessing beta-cell function in children and can help pediatricians in the differential diagnoses of diabetes mellitus in children. [ABSTRACT FROM AUTHOR]

Goals Of Work: To identify the willingness, influencing factors, and educational needs of community physicians in providing palliative care in the rural areas of Taiwan.Methods: A questionnaire was sent to all medical directors of the 140 government health stations assigned to the rural areas of Taiwan.Results: The overall response rate was 62.8% with 85 valid questionnaires retrieved. The majority of respondents (84.7%) expressed a willingness to provide palliative care if they encountered an advanced cancer patient. However, they would limit their services to consultation and referral (93.0% and 87.5%, respectively), and were less likely to provide home visits (40.3%) or bereavement support of the family (29.2%). With respect to knowledge, the accurate answers to the philosophy/principles and clinical practice of palliative care were 93.4% and 57.3%, respectively. Regarding attitudes, the highest score item in perceiving the threat about providing palliative care was "uncomfortable to meet and take care of the advanced cancer patient." The highest score item in perceiving barriers was "providing palliative care may shorten patient's life, just like euthanasia." The results of stepwise logistic regression analysis for the willingness to provide home visits showed that only the subjective norms remained in the model (OR = 1.87, 95% CI = 1.17-3.01). Educational needs expressed by the respondents were ranked as follows: emotional support to, communication skills with, and bereavement support for the advanced cancer patients and their relatives.Conclusions: Effective training courses that emphasize the practical knowledge of palliative care for community physicians, incorporating palliative care into medical education particularly in terms of communication skills and ethical roles, and active health policy administration including insurance payments, are important for the enhancement of community palliative care in Taiwan.
