An unusual foreign body in hand. A case report

Small sharp foreign bodies are common in dominant hand. A case of an unusual, large, blunt, metallic foreign body in the non-dominant hand, with treatment and result, is reported.

Fracture of the head of the radius treated by elbow cast

The management of fractures of the radial head is still a controversial subject. Fifty cases of radial head fractures have been treated by conservative means. These cases were immobilized in a plaster Paris cylinder cast for 3 weeks to restrict the movement of flexion and extension at the elbow, while encouraging supination and pronation movements from the very beginning. The cases have been evaluated and 43/50 have shown excellent results.

Excurrent duct system in male rabbit: a morphological study

The present study was carried out to determine the detailed histological and cytological features of the excurrent ducts of the male reproductive system in the rabbit. The rete testis is comprised of flattened epithelium surrounding a wide lumen which is devoid of spermatozoa. Vasaefferentia epithelium is comprised mainly of ciliated and non-ciliated cells and the lumen is devoid of sperms. On the basis of the characteristics of the epithelium, and luminal contents and histometric observations such as luminal diameter, epithelial cell height and stereocilia height, seven regions of epididymis were identified. Similarly, the vas deferens was identified into 3 regions; proximal, distal and terminal. Results were discussed bearing in mind the functional significance of different regions.

Ultrastructural changes in rabbit testis and epididymis following vasectomy: a long term study

The Ultrastructural changes in testis and epididymis were studied in rabbits following 18 months of bilateral vasectomy. No fine structural changes were observed in seminiferous tubules and all stages of spermatogenesis appeared normal in most of the sample studied. Intracellular spaces in the spermatogonia cytoplasm may denote ionic deficiency. Digestion of sperms to some extent in the lumen of seminiferous tubules was denoted by the presence of round membrane bound bodies which may be remnants of digested cytoplasmic organelles and sperm parts. Cells of the epididymal epithelium showed normal characteristics. Electron dense bodies (lysosomes) were more prevalent in the supranuclear region of principal cells suggesting increased resorption capacity of caput epididymis after vasectomy. Presence of large oval bodies in the lumen needs further investigation.

Statistical models relating peak expiratory flow rates to age, height, and weight in men and women

An epidemiological survey of 1239 normal subjects without respiratory symptoms was undertaken in an urban locality of New Delhi in 1974. The subjects were divided into males aged under or over 22 and females under or over 17. Various statistical models were calculated to relate peak expiratory flow rate to the age, height, and weight of the subjects in each group. The linear model was simple, convenient, and adequately explained the variation in peak expiratory flow rate.

Diazepam and succinylcholine-induced muscle pains

Postoperative muscle pains occurred in 16% of 25 patients given 10 mg diazepam IV 5 minutes prior to succinylcholine. Postoperative muscle pains occurred in 60% of 25 patients not given diazepam before succinylcholine. The difference is statistically significant. Diazepam reduced the severity and duration of postoperative muscle pains, as well as their frequency.
