Resolution of homonymous visual field loss documented with functional magnetic resonance and diffusion tensor imaging.

A 68-year-old man developed right homonymous hemianopic paracentral scotomas from acute infarction of the left extrastriate area. He was studied over the ensuing 12 months with visual fields, conventional MRI, functional MRI (fMRI), and diffusion tensor imaging (DTI). As the visual field defect became smaller, fMRI demonstrated progressively larger areas of cortical activation. DTI initially showed that the lesioned posterior optic radiations were completely interrupted. This interruption lessened in time and had disappeared by one year after onset. fMRI and DTI are innovative measures to follow functional and structural recovery in the central nervous system. This is the first reported application of these imaging techniques to acute cerebral visual field disorders.     

Retrorenal colon: implications for percutaneous diskectomy

It has been recommended that computed tomography (CT) with the patient prone be performed in every patient undergoing percutaneous diskectomy; this would enable detection of a retrorenal location of the colon, which could interfere with the percutaneous procedure. In this evaluation of 346 prone CT studies, only one patient (0.29%) was found to have retrorenal or retropsoas bowel that would have been perforated at diskectomy. Because of this extremely low prevalence, the performance of prone CT in every patient undergoing percutaneous lumbar diskectomy is not believed to be necessary.     

Ultrasound biomicroscopic features of spherophakia

Background: Spherophakia is an uncommon diagnosis. This is the first case report of spherophakia evaluated by ultrasound biomicroscopy.
Methods: Ultrasound biomicroscopy is a new diagnostic technique developed by one of the authors and provides images with microscopic resolution of the anterior segment. A patient with spherophakia was evaluated by ultrasound biomicroscopy (Zeiss-Humphrey, 50MHz) before and after YAG laser iridotomy.
Results: Ultrasound biomicroscopic assessment revealed a shallow anterior chamber, a very steep anterior lens curvature, iridolenticular contact, elongated zonules, and an increased distance between the lens equator and the ciliary processes. Angle closure glaucoma was due to a pupil block mechanism. The pupil block was relieved by YAG laser iridotomy.
Conclusions: Ultrasound biomicroscopy is a useful technique to confirm the diagnosis of spherophakia. The pupil block in spherophakia is relieved by YAG laser iridotomy.

1,6—二磷酸果糖对手术后应激病人应用全肠外营养支持效果的影响

本文在胃癌行全胃或胃大部切除术引起的中等程度应激病人，随机分组对比观察了全肠外营养或ＴＰＮ加用１，６－二磷酸果糖的效果。结果显示，与单纯ＴＰＮ相比，ＴＰＮ加用ＦＤＰ后血清皮质醇和胰高血糖素等应激激素水平有所下降，尿中３－甲基组氨酸排出减少，累积氮平衡增加。     

纤维素固相放射免疫测定甲胎蛋白

本文在国内首次报道了纤维素固相RIA法测定甲胎蛋白。本法简便灵敏,快迅稳定,平均回收率95.7±8.08％,批间变异系数r=7.8±1.7％,批内变异系数r=5.8±2.6％,线性关系较好(r=0.999),灵敏度比液相RIA提高6倍,32份血样品用双位点夹心法和试剂盒的液相RIA进行比较,结果经统计学处理,相关系数分别为r=0.82,r=0.80,均具有显著相关性。
