Isolated tubercular splenic abscess.

Splenic abscess due to tuberculosis is extremely rare in immunocompetent individuals. We report a case of tubercular splenic abscess (TSA) in an immunocompetent individual for its rarity.

Perforation of small intestine caused by Churg-Strauss syndrome.

In Churug-Strauss Syndrome (CSS), gastrointestinal tract (GIT) is an uncommon site of involvement. In addition to review of recent literature, we herein report a case of CSS with unusual involvement of GIT. The patient was being treated for idiopathic hypereosinophilic syndrome for 2 years; he later developed acute peritonitis and an emergency laparotomy revealed 3-cm-diameter perforation in the small intestine. In order to establish a correlation between the clinical features and the histopathological findings, we highlight the importance of adequate sampling and examination of mesenteric vessels in the attached mesentry in the resected specimen.

Comparative evaluation of intramuscular buprenorphine, pentazocine and nefopam in post-operative pain relief.

In immediate postoperative period, many injectable analgesics are being used with diverse side effects. The present study was conducted on 75 patients of both sexes, who underwent various types of surgery, to evaluate pain relief in immediate postoperative period. The drugs used for producing postoperative analgesia are buprenorphine, pentazocine and nefopam, all by intramuscular route.

Sperm motility, velocity and migration.

Four different methods for evaluating sperm motility were analysed for experimental error: subjective assessment of a wet film preparation, sperm velocity measured by time-lapse photography, sperm velocity measured by computer analysis and sperm migration across a nucleopore membrane. Subjective assessment of motility was found to be inaccurate, within single observer and between 2 observers. Both methods of measuring mean sperm velocity were accurate, particularly that using the computer analysis system; a high technical failure rate was found using time-lapse photography. Sperm migration across a nucleopore membrane was found to be highly inaccurate. Two groups were then analysed for the predictive value of these tests (excluding sperm migration): 104 proven fertile men and 53 infertile men. Although subjective motility was able to predict from which group the sample came at optimum cut-off with 78% accuracy, computer analysed sperm velocity could predict with overall 91% accuracy at optimum cut-off. Computer analysis of sperm velocity offers a rapid, objective and predictive assessment of sperm function.

Hemangioendothelioma of the mandible: report of case.

A case of hemangioendothelioma of the mandible, the third of its kind to involve the jawbone is reported. The radiological appearance of new bone formation is a unique feature in this case. The vascular malignant tumor has a poor prognosis.

Chemotherapeutic evaluation of N-(4-hydroxyphenyl) retinamide-O-glucuronide in the rat mammary tumor model.

The growth inhibitory effects of N-(4- Hydroxyphenyl) retinamide (4-HPR) and its glucuronide derivative, N-(4-Hydroxyphenyl) retinamide-O-glucuronide (4-HPROG) on established DMBA induced rat mammary tumors were compared. The results indicate that the glucuronide analog had a greater antitumor potency than equimolar concentration of the free retinoid. Tumor regression occurred in 75% of the rats fed 2 mmol/Kg diet of 4-HPROG. In a 6-week study, the maximum tolerated dietary dose (MTD) was found to be 3.5 mmol/Kg diet for 4-HPR and 5 mmol/Kg diet in the case of 4-HPROG. The higher potency and lower toxicity of the glucuronide suggests that this conjugate may have an in vivo chemotherapeutic advantage over the parent free retinoid.
