Summary A questionnaire survey was carried out to explore differences in the approach to treatment of patients with Type II diabetes between physicians in Northern Ireland, Norway and Sweden, and to discover to what extent it could account for the three-fold difference in drug use between the countries. A representative sample of 400 physicians in each country was asked to give their opinions on the choice of therapy for three model cases designed to cover the spectrum of treatment — from diet alone to insulin. Significantly more Swedish (65%) than Northern Irish (51%) and Norwegian (52%) doctors suggested diet alone for uncomplicated diabetes recently discovered in a middle aged, overweight man. For symptomatic diabetes in a 76 year old overweight woman with few retinal microaneurysms, the majority of physicians in all three countries suggested treatment with sulphonylureas. Biguanides were here a more common alternative in Northern Ireland than in Scandinavia. For suspected secondary treatment failure in a 63 year old woman with no signs of complications, insulin was suggested by 71% of the Norwegian doctors but only by 44 and 49% of those in Northern Ireland and Sweden, respectively. General practitioners tended to suggest oral treatment earlier and to maintain it longer than hospital physicians. The study has demonstrated significant differences in the approach to treatment of Type II diabetes mellitus between physicians in the three countries. However, the differences were more prominent in the choice of drugs than in the threshold of drug treatment. The results also fit with qualitative but not with quantitative differences in drug sales between the countries, suggesting that important differences may exist in the prevalence of clinically recognized Type II diabetes. 相似文献

Both the phytopathogenic fungus Ramularia collo-cygni and the hyperparasite R. uredinicola biosynthesize a number of red and yellow anthraquinone derivatives called rubellins. The new compounds uredinorubellins I and II, which were isolated from R. uredinicola, contribute to understanding the biosynthesis pathway that leads from simple anthraquinones to the rubellins. In addition, we isolated for the first time such simple compounds as chrysophanol and helminthsporin from both Ramularia species. A blue compound isolated from the mycelium of R. collo-cygni was revealed to be a unique 9,4-anthracenedione derivative. Structure elucidation by (1)H and (13)C NMR of the new but unstable compound caeruleoramularin was possible only by feeding the fungus different labeled (13)C acetates. The photodynamic activity of the uredinorubellins was comparable to rubellin D, whereas chrysophanol and caeruleoramularin did not display such activity. 相似文献

AIMS: To analyze diagnosis and treatment of four advanced abdominal pregnancies in a low-resource setting of a developing country. METHODS: Extrauterine pregnancies occurring between 1997 and 2003 were identified from hospital records of the Mikumi Health Center in Tanzania/East Africa. RESULTS: A total of 45 extrauterine pregnancies were diagnosed four of which were advanced and located in the abdominal cavity. At the time of diagnosis, pregnancies were at 33, 34, 36 and 39 weeks of gestation, respectively. All four mothers survived but three of four fetuses died. One child is alive and well three years after delivery. CONCLUSION: Abdominal pregnancy is rather difficult to detect in a low-resource setting of a developing country. Persistent abdominal pain and tenderness, as well as fetal movements in the upper abdomen associated with abnormal fetal lie, may lead to its diagnosis. Localizing the fetal heart sounds in the maternal epigastrium especially in patients with abdominal pain may also be helpful in diagnosing an abdominal pregnancy. In addition, the lack of cervical changes or a displaced cervix should lead to the suspicion of an abdominal pregnancy. 相似文献
