OBJECTIVE: To assess the results of Martius' labial fat pad interposition and its modification using skin island in the repair of giant and recurrent vesicovaginal and urethrovaginal fistulae. PATIENTS AND METHODS: Fifteen patients of urethrovaginal and vesicovaginal fistulae underwent Martius' labial fat pad interposition and its skin island modification during 1996 to 1999. Ten of these were recurrent (66%) and five were giant fistulae (34%) i.e. more than five cms. RESULTS: Results were very gratifying with a successful repair in 14 patients (93%). Two patients had transient, low-grade stress incontinence, which did not need any additional procedure. In one patient, there was failure of repair, which was later successfully repaired using fat pad from opposite labia. CONCLUSION: Martius' fat pad interposition provides vascularity and surface for epithelialisation and also prevents overlapping of vesical/urethral and vaginal suture lines. Martius' repair has good results with low morbidity in the treatment of giant and recurrent urethrovaginal and vesicovaginal fistulae.

Posterior pituitary ectopia refers to an absent normal posterior pituitary bright spot within the sella with ectopic bright signal at another site (such as the median eminence) on a weighted magnetic resonance. We describe two children with idiopathic anterior hypopituitarism who showed an ectopic posterior pituitary and absent pituitary stalk on imaging. We emphasize the association of the absent pituitary stalk in ectopic pituitary gland and low growth hormone levels.

Sixty patients in the age group of 18-60 years of A.S.A. Grade I/II risk, scheduled for elective orthopaedic surgeries under general anaesthesia were studied for pre-medication with either oral clonidine or with combination of effects of diazepam & atropine. Patients in Group A (clonidine group) received tablet clonidine 100 mcg (1 tablet) if less than 50 kg in weight and 200 mcg if weighing more than 50 kg two hours before surgery. Patients in Group B (Diazepam-atropine group) received one tablet of Diazepam (10 mg) orally two hours before surgery and injection atropine-sulphate 0.01 mg/kg half an hour preoperatively by intramuscular route. In our study, the sedative and anti-sialogogue effects of clonidine were comparable to those of diazepam-atropine combination, which are commonly used premedicants. The anti-anxiety effect of clonidine was found to be better than that of diazepam-atropine combination. Clonidine also proved to be a better agent for the attenuation of pressor response to laryngoscopy and intubation. Thus, oral clonidine is a better premedicant compared to atropine-diazepam combination. Also, it is a more acceptable agent because of its oral route of administration.

Sixty-one patients with anovulation as a cause of infertility were selected for our study. Various ovulation-inducing drugs were used like clomiphene citrate, human menopausal gonadotropin (hMG), human chorionic gonadotropin (hCG), bromergocryptine and leptadene. The response of the different drugs was observed by serial sonography for ovulation. Indeed there was a good response to clomiphene citrate, but those patients who failed to respond to clomiphene citrate and were frustrated with the use of hMG and hCG due to the cost and the complications of the therapy were put on Aloe compound and leptadene - an ayurvedic drug which enhances fertility in different ways.
