Resolving duodenal-jejunal hematoma in abused children

Acute intramural duodenal-jejunal hematoma is a classical finding in the battered child syndrome. The radiographic findings of a large obstructing intramural mass associated with the "coiled-spring" appearance generally raise the question of child abuse in any patient without appropriate accidental injury. In this study the radiologic features of resolving duodenal-jejunal hematoma are detailed in five abused children. The results show that the coiled-spring appearance is an acute phenomenon associated with a well-localized intramural hematoma. In the resolving phase, localized mural masses in the lateral aspect of the descending duodenum and fold thickening are indications of prior intramural hemorrhage. When these radiologic features are encountered in a child with nonspecific abdominal complaints, child abuse should be suspected. Furthermore, in patients with suspected occult trauma, resolution of abdominal symptoms should not deter the radiologist from performing an upper gastrointestinal tract series, which may provide evidence of child abuse.     

SPECTRUM OF ACUTE RENAL FAILURE IN A SERVICE HOSPITAL

A prospective study of 82 patients with acute renal failure was carried out over the last 2 years. Mean age of the patients was 35.6 years (8-82 years). Male to female ratio was 3.5:1. The etiological factors were septicaemia in 18 patients (21.95%), aminoglycoside toxicity in 16 patients (19.51%), open heart surgery in 8 patients (9.76%), volume depletion and blood loss in 12 patients (14.63%), glomerulonephritis in 4 patients (4.88%), renal allograft dysfunction in 4 patients (4.88%), and miscellaneous causes in 20 patients (24.39%). Non-oliguric renal failure was observed in 39.02 per cent cases. Dialysis support was required in 65.8 per cent of the cases; with average 5.6 (4 to 11) dialysis sessions. Four patients of acute renal failure following open heart surgery were given continuous arterio-venous haemofiltration. Overall mortality was 32.5 per cent, septicaemia accounting for 60 per cent of the deaths.KEYWORDS: Antibiotics, Aminoglycoside, Renal failure acute, Septicemia     

内镜下扩大经鼻蝶入路至斜坡区的解剖学研究

目的探索内镜下经扩大鼻蝶入路显露斜坡区的可行性,为切除斜坡区病变提供解剖学参考。方法在10例成人头部固定标本上,内镜下模拟扩大经鼻蝶手术入路显露斜坡区,观察有关显微解剖标志。结果扩大经鼻蝶内镜入路可磨除从鞍后到斜坡、枕骨大孔前缘的骨性结构;可显露斜坡区腹侧硬膜下的椎基底动脉及其分支、后交通动脉及其与大脑后动脉汇合处、动眼神经、脑干腹侧等结构。此入路的手术标志主要包括:蝶筛隐窝、蝶窦开口、视神经隆突、颈内动脉隆突与颈内动脉视神经隐窝、咽结节、枕骨大孔前缘。结论内镜下扩大经鼻蝶手术入路可充分显露鞍后-斜坡区的腹侧硬膜下结构,适用于此区病变的手术治疗。
