RESUMO
Ancient schwannomas are benign tumours arising from the neural sheath of peripheral, cranial and autonomic nerves. They are commonly situated in the inner ear and spine with pelvic manifestations being rare. We present the case of a 30-year-old patient, who presented with an abdominal mass. MRI imaging suggested a broad ligament fibroid and open surgery was undertaken to remove it. Subsequent histology confirmed an ancient schwannoma. This case report details the rarity of such a condition and the need for a high index of suspicion as well as outlining management options and surveillance.
RESUMO
Medroxyprogesterone acetate is the most commonly used progestin component of hormone therapy. The goal of the present study was to determine whether Medroxyprogesterone affects rat behavior using a Y-maze test. Twenty-four female Wistar rats were randomly selected into three groups; control group, a low dose (13 mg/ml MPA) group and a high dose (33 mg/1 ml MPA) group. Doses of Medroxyprogesterone were delivered by intramuscular injection for a period of 3 weeks. Medroxyprogesterone administration resulted in a decrease in memory and locomotion activity of rats (p < 0.05). Despite Medroxyprogesterone being effective in modulating hormonal interaction to prevent conception in actively reproducing females, cognitive impairment could be one of its adverse effects.
