经皮肾穿气压弹道碎石联合体外冲击波碎石治疗上尿路结石

目的 探讨提高上尿路结石碎石成功率的微创治疗方法。方法 采用经皮肾穿微造瘘输尿管镜气压弹道碎石，术中放置双J管，术后配合体外冲击波碎石术(ESWL)治疗上尿路结石48例。结果 结石总排净率为89．1％，结石最小排净率79．2％，无严重并发症发生。结论 该方法结石排净率高，创伤较小，手术并发症少，是上尿路结石较为理想的微创治疗方法。     

ENDOSCOPIC PANCREATIC STENTING IN CHRONIC PANCREATITIS WITH DUCTAL DILATION PROXIMAL TO A STRICTURE: A SAFE and EFFECTIVE PROTOCOL

After removal of intraductal stones, a 10‐Fr or 7‐Fr pancreatic stent was placed in 16 patients with upstream ductal dilation proximal to a stricture of the main pancreatic duct. Stents were removed after a mean duration of 52.5 days. Nine patients underwent repeated stenting. About one year after removal of the initial stent, when the remaining upstream ductal dilation was found on follow‐up pancreatograms, the next stent was replaced. Repeated stenting improved outflow of pancreatic juice more effectively than one‐time stenting. Correlation between long‐term pain relief without recurrence of intraductal stones and reduction of duct diameter was also shown. Stent occlusion was observed in 14 of 30 stents. Stent occlusion was frequently associated with recurrence of pancreatitis and intraductal stones, and was also associated with morphologic changes in the pancreatic ductal system. Although there were no significant differences between stent patency of the initial stents and that of the next stents, stent patency of 10‐Fr stents was superior to that of 7‐Fr stents. 10‐Fr stents should be removed within 8 weeks and 7‐Fr stents should be removed within 4 weeks for the prevention of stent occlusion. Repeated stenting with short‐term stenting is therefore considered a safe and effective protocol of endoscopic pancreatic stenting.     

Models for psychosocial services in the developed and developing world

Summary.  This paper is based on the assumption that psychosocial services can add important mental and social dimensions to the traditional concepts of help and medicine. Peer support which has been established world-wide for people with haemophilia and their families is invaluable and irreplaceable. However the role of the professional psychosocial worker is underutilized in most countries, mostly because of lack of financial resources. This paper will argue that skilled workers can assist individuals and groups to reach their full potential in a variety of creative and non-threatening ways. Psychosocial workers have strict codes of conduct and requirements relating to accreditation to ensure accountability in their work. They can work in a variety of individual roles and have a wide range of individual mandates within work settings.     

Bilateral naevus of Ota: a rare manifestation in a Caucasian

The naevus of Ota (naevus fusculocoeruleus ophthalmomaxillaris) was first described by the Japanese dermatologist M. T. Ota in 1939. It has a reported incidence of 0.2% to 1% in the Japanese population. It usually occurs in the skin innervated by the first or second branch of the trigeminal nerve. The naevus comprises dermal melanocytes and is congenital or acquired during adolescence. Commonly associated lesions include scleral melanocytosis and other ocular manifestations as well as lesions of the tympanic membrane, oral and intranasal mucosa and leptomeninges. Diseases associated with Ota's naevus in rare cases are open-angle glaucomas and melanoma. The naevus of Ota in Europeans is a rare manifestation. We report the very rare case of a bilateral naevus of Ota associated with enoral melanocytosis in a white European person.     

Causality Between the Amplitude and Frequency of Cardiac Oscillations

Using an information-theoretic approach, causality between the systolic amplitude in blood pressure and the frequency of the heart beat was analyzed. Blood pressure and ECG were noninvasively recorded in young, healthy subjects. Three successive measurements were performed: during spontaneous breathing and during paced respiration—at frequencies both higher and lower than that of spontaneous respiration. We demonstrate that the amplitude and frequency of the cardiac rhythm are synchronized for most of the time. The synchronization is stronger during paced respiration at a frequency lower than that of spontaneous breathing. Episodes where the cardiac frequency was driven by the systolic pressure were also detected during slow, paced respiration.

行为干预对康复期精神分裂症患者应对方式和生活质量的作用

目的:探讨行为干预对精神分裂症应对方式和生活质量的作用。方法:将入组患者随机分为实验组和对照组,对实验组患者进行为期一年的行为干预,研究结束时分别用简易应对方式问卷和综合生活质量量表进行评定。结果:实验组复发率和服药依从性与对照组相比均有显著差异(X2=4.29,p<0.05 X2=8.95,p<0.005)。实验组积极、消极应对因子与对照组相比差异显著(t=2.24,p<0.05.t=-2.46,p<0.05)。实验组躯体功能、心理功能、社会功能各维度分与对照组相比均有显著差异(t=2.25～2.92,p<0.05～p<0.01)。结论:对精神分裂症患者进行行为干预可提高患者的应对能力,减少复发,提高生活质量。
