Acute renal failure as a result of bilateral ureteral obstruction by Candida albicans fungus balls

A 73-year-old male with a history of diabetes mellitus was admitted to our hospital for acute renal failure. An ultrasonogram revealed bilateral hydronephrosis, which worsened despite insertion of a bladder catheter. Nephrostomy catheters were positioned bilaterally, and Candida albicans was found in the urine culture. The patient was successfully treated with intermittent direct irrigation and i.v. antifungal agent therapy. Since 1977, approximately 50 cases of fungus balls or fungal bezoars in the urinary tract have been reported, but the majority of these cases have been characterized by unilateral ureteral or bladder involvement. Herein, we report a case of acute renal failure as a result of bilateral ureteral obstruction by Candida albicans fungus balls.     

重症胆管炎23例临床治疗分析

目的：探讨急性重症胆管炎患者的手术时机和死亡原因。方法：回顾性分析23例急性重症胆管炎患者的治疗及预后情况。结果：死亡2例（手术死亡及传统治疗死亡各1例）。早期大剂量短期应用糖皮质激素患者休克得到纠正率85％，明显高于未用糖皮质激素患者休克纠正率50％。结论：急性重症胆管炎患者应在出现休克和（或）精神症状之前手术，对已出现休克的患者，应先给予充分的保守治疗，待病情稳定后再手术。贻误手术时机，严重合并症如多器官功能衰竭及高龄是死亡的主要原因。     

腹腔镜胆囊切除术360例Calot三角解剖与临床

目的 通过腹腔镜胆囊切除术(Laparoscopic Cholecystec-tomy，LC)，探讨Calot三角的解剖关系。方法 从Calot三角分离出胆囊动脉、胆囊管，辨认胆总管和肝总管的走向。结果 我们1998年9月～2004年6月共完成360例LC术进行分析。结论 解剖Calot三角是胆囊切除术中重要的步骤，也是预防医源性损伤的关键。     

The shape of stress: the use of frequent sampling to measure temporal variation in S‐IgA levels during acute stress

Previous studies have indicated that statistically significant increases in Secretory immunoglobulin A (S‐IgA) can be achieved in as little as 5min as a result of mental stress. However, the temporal resolution of these changes is low and therefore the rate and pattern of changes during the stress task and during subsequent recovery is unclear. A within‐subjects design was used to examine levels of S‐IgA before, during and after a short (8 min) mental stress task. S‐IgA was measured from saliva samples obtained every 2 min during the entire 30‐min session. Significant increases in S‐IgA concentration were observed as early as the task instruction period, with additional increases during the stress task itself. The data also show a rapid recovery of S‐IgA, with a return to baseline levels within 6 min. Results suggest that S‐IgA changes can occur very rapidly and that the observed increases are short‐lived.
