Spinal cord compression from metastasizing cicatrial carcinoma: a case report

Spinal cord compression from a metastasizing burn scar cancer has not previously been reported. A patient with rapidly progressive paraparesis associated with vertebral collapse and an extradural soft tissue mass of undetermined origin is presented. The clinical history, radiological diagnosis, and histological features of cicatrial carcinoma are discussed along with a brief review of the relevant literature.     

Ureteral catheterization and manipulations using flexible cystoscope on patients in semiprone position

Cystoscopy using the flexible cystoscope was performed on 15 patients in the semiprone position. Ureteral catheters were placed to facilitate percutaneous nephrolithotomy in 8 patients, and indwelling ureteral stents were removed in 7. The procedure offers the urologist an additional technique in select situations.     

Twenty-four-hour intragastric acidity and clinical trial of bedtime enprostil 70 μg compared with ranitidine 300 mg in duodenal ulcer

The effects of bedtime 70 micrograms and twice daily 35 micrograms doses of enprostil on 24-hour intragastric acidity were investigated in nine duodenal ulcer patients in remission. Median nocturnal acidity decreased significantly by 30% with 35 micrograms twice daily, and by 48% with 70 micrograms at bedtime. In a clinical trial using bedtime dosing, 102 duodenal ulcer patients randomly received either ranitidine 300 mg or enprostil 70 micrograms. More ulcers healed after 4 and 8 weeks treatment with ranitidine than with enprostil (76% ranitidine vs 52% enprostil, at 4 weeks p = 0.0065 and 94% vs 68%, respectively at 8 weeks, P = 0.0007). However, 6 months after cessation of treatment there was no material difference in overall outcome. Despite combining mucosal protection with acid inhibition enprostil treatment conferred no advantage over simple acid inhibition.     

Plasma concentrations of mianserin after single dose and at steady-state in depressed elderly patients

Plasma mianserin and desmethylmianserin concentrations were measured in 17 clinically depressed elderly patients after a single 30 mg dose of mianserin. The patients then received mianserin 30 mg daily for up to 6 weeks and the plasma concentrations were measured at weekly intervals. The relationship between concentrations of mianserin and desmethylmianserin at steady-state and at 16 and 24 hours after the single test dose was not good enough to be used for prediction of dosage requirements. Reasons for this finding are discussed.
