Ossifying fibroma of the sella turcica.

Ossifying fibroma of the sellar turcica is extremely rare. There are only sporadic case reports in the literature. One such case simulating pituitary adenoma is presented in an 18-year-old girl.     

Development of medicated aerosol dressings of chlorhexidine acetate with hemostatics.

Aerosol formulations to act as medicated aerosol dressings have been prepared with an aim of forming a protective film over the wound after spraying combining the properties of antiseptics and hemostatics. Chlorhexidine acetate along with three hemostatics namely zinc acetate, methyl cellulose and Calendula tincture were used for the formulations. The formulations were found to be satisfactory in their performance and purpose.     

Ipsilateral Coat's reaction in the eye of a child with en coup de sabre morphoea--a case report.

A female child with post-traumatic en coup de sabre type of morphoea (fronto-parietal circumscribed scleroderma) involving the left side of the forehead and face, who developed a Coat's disease-like fundus picture over the following two years, is being reported.     

Effect of peripheral administration of cinnarizine and verapamil on the abstinence syndrome in diazepam-dependent rats

The effects of two calcium channel blockers (verapamil and cinnarizine) were evaluated on diazepam withdrawal symptoms. Rats were made diazepam dependent by chronic treatment with daily injections of the drug, 20 mg/kg IP for 3 weeks. On abrupt termination of the drug, animals showed withdrawal hyperactivity that was assessed by autonomic, behavioural and motor signs. The peak effect was seen 3 days after the withdrawal of diazepam. On IP administration, verapamil and cinnarizine (10, 20 and 40 mg/kg) given on eight occasions at an interval of 12 h reversed the withdrawal-induced increase in spontaneous motor activity. Cinnarizine in higher doses (20 and 40 mg/kg) was found to be effective in suppressing the behavioural signs but verapamil did not show any protective effect against startle response and irritability. These results suggest that modulation of the calcium influx in the CNS might influence withdrawal.This study was presented in XIth International Congress of Pharmacology (IUPHAR) at Amsterdam (July 1–6, 1990)     

Are intravenous corticosteroids required in status asthmaticus?

Seventy-seven patients with status asthmaticus were prospectively studied to compare oral with intravenous methylprednisolone. Patients were given methylprednisolone, either 160 or 320 mg orally or 500 or 1000 mg intravenously, daily in equally divided doses. They were randomly assigned to either group on a daily sequential basis. Spirometry was performed within one hour of the initial dose of steroids. The mean presenting forced expiratory volume in 1 s was 26% of the predicted value. Spirometry was then repeated every six hours for the first 24 hours and then every eight to 12 hours until discharge or 72 hours, whichever occurred first. There were no significant differences in the incidence of respiratory failure, forced expiratory volume in 1 s, days of hospitalization, rate of improvement in pulmonary function, or side effects. No patient who went into respiratory failure did so more than three hours after receiving the initial dose of steroids. We conclude that oral methylprednisolone is safe and effective in the treatment of status asthmaticus.
