Crossed hemifacial hyperplasia: a diagnostic dilemma.

Crossed hemifacial hyperplasia is a rare condition producing facial asymmetry and overgrowth of the extremities of the opposite side. Very few cases are reported in literature. A case of an 11-year-old female is presented here to supplement existing clinical knowledge with many of the reported clinical and orofacial findings. Emphasis is placed on diagnosis of the condition by thoughtful elimination and the necessity of a multi-disciplinary approach to its management.

Evaluation of intraperitoneal vincristine in malignant peritoneal effusion.

The efficacy and safety of intraperitoneal administration of vincristine sulphate was determined in mice bearing Ehrlich ascitic carcinoma. The tumor bearing animals were administered with 0.5 mg/kg body weight (b.wt) of freshly prepared vincristine sulphate intraperitoneally on day 6 after tumor transplantation followed by drug administration once daily 5 days a week consecutively. The observations regarding the survival, alteration in the volume of peritoneal fluid, increase in life span and pathological changes in the liver, kidney, gastrointestinal tract and bone tissues were made. The vincristine sulphate treatment reduced the malignant cell population significantly and there were no significant changes in the histological picture of liver, kidney, bone, except the intestine, where atropy of villi demonstrating nests and cords of uniform small round cells were observed. Our experimental data suggests that intraperitoneal administration of vincristine is beneficial in malignant peritoneal effusion.
