[Two cases of solid and cystic tumor of the pancreas (including one case of MRI)].

Solid and cystic tumor of pancreas is an uncommon neoplasm which is histologically low grade malignant but amenable to cure by surgical excision. It tends to occur in young women. US and CT depict a well circumscribed mass that can be solid, mixed solid and cystic and largely cystic. Their ratio depends on the degree of hemorrhage and necrosis. Angiography shows a mildly to moderately vascular mass which corresponds to solid parts. MRI is useful to detect the hemorrhage which is common in this tumor.

[In vitro antibacterial activity and pharmacokinetics of ofloxacin in chronic respiratory tract infections].

Serum and sputum levels of ofloxacin (OFLX) were measured in 5 patients with chronic respiratory tract infections and were compared with antibacterial activity in vitro. Sputum OFLX levels higher than the MIC's against H. influenzae and K. pneumoniae were maintained during the period when daily oral administrations were continued. The MIC70 of OFLX against S. aureus was under 0.78 microgram/ml and the MIC70 of OFLX against P. aeruginosa was 1.56 micrograms/ml. The maximum OFLX levels in sputum were higher than these MIC's during the period when 200-300 mg X 2 times/day oral administrations were maintained. From these results, OFLX was considered to be effective and useful for the treatment of patients with chronic respiratory tract infections.

Bleeding esophageal varices caused by Graves' hypervascular cervical goiter.

A 65-year-old woman presented with an episode of hematemesis and a recurrent cervical goiter due to Graves' disease. The angiogram revealed bleeding esophageal varices which had developed through a drainage vein of the vascular goiter. Total thyroidectomy resulted in eradication of the esophageal varices.

Suppressive effect of elcatonin, an eel calcitonin analogue, on excessive urinary hydroxyproline excretion in polyostotic fibrous dysplasia (McCune-Albright's syndrome).

A 12-year-old Japanese girl with polyostotic fibrous dysplasia and endocrine concomitants, was treated with elcatonin, a synthetic eel calcitonin analogue, 10 MRC unit/twice a week given by intramuscular injection. Significant decreases in 24 hr urinary content of hydroxyproline and other amino acids from bone collagen were observed during the course of treatment over 5 months. This biochemical result suggests that the synthetic eel calcitonin analogue exhibits the therapeutic effect in patients with polyostotic fibrous dysplasia by inhibiting bone resorption.
