We wish to report 8 cages of calyceal diverticula which were diagnosed tentatively among cases of I.V.P. during the period from January 1965 to December 1971 at St. Mary's Hospital. There were 5 male and 3 female patients. The right kidney was involved in all patients The upper calyx was involved in 6 patients and the middle calyx in 2 patients. Lumbar or abdominal pain was present in 5 patients. 1 of the 8 patients had undergone appendectomy with removal of a norma1 appendix prior to diagnosis.Pyuria were found in 3 patients and one patient had single stone within the diverticulum.

Metformin is widely marketed medication for the treatment of diabetes, but its pharmacological effect on diabetic peripheral neuropathy remains unclear. In this study, the effect of metformin on peripheral nerves in diabetic rats was investigated using diverse neuronal parameters of nerve fibers.

A 18-year-old male patient presented with the skin colored, dome-shaped, soft, movable mass in his left retroauriculr region. The mass has slowly increased in size since birth. Histopathologic exarnination revealed sebaceous gland, eccrine gland and crosssectioned hair in the surrounding tissue, hair shaft projected into the lumen, and laminated horny material in the cyst. Transitional zone between stratified squarnous epithelium and the wall lined by histiocytes showed homogenous degenerative change. After surgical removal of the lesion, no recurrence was observed during 15 months of follow-up.

Pathologists play an important role in proper evaluation of endoscopically removed polyps of the gastrointestinal tract. This study is purposed to reclassify the polyps and review the clinicopathologic features of each histologic subtypes and their malignant potential. Our material consists of total 345 gastrointestinal polyps obtained from Jan. 1986 to Dec. 1987. The results are as follows: 1) A total of 345 gastrointestinal polyps was removed from stomach is 151 cases, from colon in 180 cases, and from small intestine in 14 cases. 2) Hyperplastic polyps were the most common type of polyps I stomach (53.6%) whereas neoplastic polyps were the most common in colon (56.1%). 3) Hyperplastic polyps of the stomach occur in any age after the 3rd decade of life and neoplastic polyps predominantly developed between the 5th and 8th decades. Juvenile retention polyps were frequently noted before the 3rd decade of age. 4) Approximately 267 cases (77.4%) of patients had a single polyp and the remainders had multiple polyps. The gastric polyps were usually located at the antrum and the colonic polyps were at the sigmoid colon and rectum. 5) Epithelial atypia was exclusively noted in the neoplastic polyps of stomach (72.7%) and colon (72.3%). Malignancy in the polyp was observed in the neoplastic polyps only (13 cases). 6) Different types of polyp may occur in the same organ.
