Clean intermittent self-catheterisation for quadriplegic patients--a five year follow-up.

We present the findings of clean intermittent self-catheterisation (CISC) as a long term method of bladder management for 36 quadriplegic spinal cord injured patients, primarily at C6/C7 level, who were taught CISC between 1983 and 1987. Success in CISC was assessed by a mail survey, a telephone interview, and current sterile urine status. Twenty nine (81%) of 36 patients continued to use CISC after a mean discharge period of 2.9 years (p less than 0.001) with high levels of acceptance. Rao's V discriminant analysis showed success in CISC was affected by the interval between injury and initial self-catheterisation (Canonical Correlation Co-efficient = 1.34). Results of urinalysis for patients continuing CISC were obtained for 18 (62%) patients, 16 (88%) of whom had sterile urine. Implications of these and other findings along with reasons for cessation of CISC are discussed.     

Recurrent Cervical Abscess Due to Pyriform Sinus Fistula-A Case Report

The pyriform sinus fistula is rare congenital anomaly of either third or fourth branchial pouch, which most frequently presented itself by recurrent episodes of neck abscess for long time. Majority of patients with this anomaly presented with symptoms before 10 years and it is more common than has previously been commonly found on leftside (93%). Clinically high index of suspicion, cannulation of the tract under general anaesthesia, Direct laryngoscopy and fistulogram have freequently been successful in identifying the presence of these embryological remnants. Surgical exploration of sinus tract with its total excision, guided with cannula inside its lumen is the definitive treatment.     

Human immunodeficiency virus cultured from bone. Implications for transplantation

This study demonstrates by a virologic culture method that human immunodeficiency virus (HIV) resides in bone. After freezing, some initially positive specimens no longer yielded virus, but those that continued to yield virus were not further altered by subsequent washing, which removed essentially all marrow, or by freeze-drying. The safeguards against potential transmission of HIV by a bone allograft are principally the screening and testing methods previously described, although there may be a further reduction of the remote residual risk by the freezing step in the usual technical sequence for tissue banking by sterile techniques.     

老年人脑皮质下斑点状病灶的MRI病理基础研究

本文对29例脑标本行 MRI-病理对照研究,其中18例脑标本 MRI 检查阳性,发现脑皮质下斑点状病灶(Subcortical Patchy Lesions,SPLs)95个。该病灶分两大类:第一类(64个)位于脑皮层下白质、基底核、小脑和脑干,其病理基础主要为血管周围间隙扩大(83%),小梗塞灶(11%),其他还有小动、静脉畸形(AVM),脱髓鞘灶和胶质增生灶;第二类(31个)位于侧脑室周围白质内,其病理基础为局部组织结构疏松呈空泡状,病灶相应部位的室管膜大片脱落。
