The role of somatic complaints in the diagnosis of depression in children and adolescents

The question of whether somatic complaints are a significant feature of depression independent of anxiety was explored. Structured interview (Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children) and Child Behavior Checklist data from depressed and nondepressed psychiatric controls were analyzed to explore the interaction of somatic complaints, anxiety, and depression. Seventy percent of the children who met criteria for depression also had significant somatic complaints in contrast to 34% of the controls. Findings revealed that frequency of somatic complaints increased with severity of depression regardless of coexisting anxiety.     

Acquired venous disease of the lower urinary tract

Thrombosis of the vena cava, femoral veins or iliac veins can result in the formation of large collateral veins in the pelvis and retroperitoneum which are often asymptomatic but which may cause severe bleeding and produce major difficulties in urological management. Such abnormalities are a rare cause of urological symptoms but may be difficult to diagnose unless a high index of suspicion is maintained. Three patients are reported who developed significant urological problems as a consequence of acquired venous disease; the use of ultrasound, venography and CT in the diagnosis of this condition is described.     

Altered motility and bacterial flora after functional end-to-end anastomosis

The functional end-to-end technique with a gastrointestinal stapler is commonly used for small-bowel anastomosis, but the effects of this anatomically side-to-side anastomosis on motility are unknown. Fasting small-bowel myoelectric activity and culture results were compared in six animals undergoing handsewn end-to-end and functional end-to-end anastomoses. Serosal electrodes were placed at 10 cm intervals, and the small bowel was divided 25 and 55 cm from the ligament of Treitz. The functional end-to-end and end-to-end techniques were performed in each animal in random order. Fasting myoelectric recordings were obtained at weekly intervals for up to 20 weeks after operation. New electrodes were placed, and additional recordings were obtained from 29 to 39 weeks, 51 to 63 weeks, and 108 to 112 weeks after operation. The recordings were visually inspected for passage of phase 3 of the migrating myoelectric complex (MMC). By 12 to 20 weeks after operation, 91% of MMCs crossed the end-to-end anastomoses versus 22% across the functional end-to-end anastomosis (p less than 0.001). Even 2 years after surgery only 56% of MMCs crossed the functional end-to-end anastomosis. Quantitative bacterial cultures suggested a trend toward bacterial overgrowth in the functional end-to-end anastomosis. These results demonstrate that the functional end-to-end anastomosis alters small-bowel motility to a greater degree than an end-to-end anastomosis and may predispose to bacterial overgrowth.     

腕管综合征主要症状体征敏感性与特异性的比较

目的　比较腕管综合征 (carpaltunnelsyndrome ,CTS)主要症状、体征的敏感性与特异性。方法　对 10 1例 ( 162只手 )进行症状严重程度与功能状况的询问 ,感觉、运动功能的检查 ;其中 62只手在术后 6周再次测定。结果　 162只患手中 15 8只具有典型症状 ( 98% )。Phalen征、前臂正中神经加压征、Semmes Weinstein单丝纤维测试阳性率分别为 98%、96%、82 %。 87%的患手出现肌力下降 ,拇短展肌肌力测定 (定量法 )结果显示 ,与徒手法相比 ,不同性别间、术前与术后的差异均具非常显著意义 (P <0 .0 1)。结论　典型症状、Phalen征、前臂正中神经加压征、拇短展肌肌力变化的敏感性与特异性最高 ,拇短展肌肌力定量法测定是判断腕管综合征严重程度、评定疗效的一个良好的客观指标。
