We report a case of dilated pare of Winer occuring in a 33-year-oid female patient. Dilated pore belongs to adenoma or organoid group of benign hair differentiation tumors. The patient has had a giant comedone on the right submandibular area for 1 month. Histopathologic features revealed rnarkedly dilated pilar infundibulum lined by epidermis that is atrophic near the ostium but hypertrophic deeper in the cystic cavity. Three months after excisional biopsy, there was no recurrence.

Many urologists began to abandon ureterosigmoidostomy as the preferred method of diversion nearly 35 years ago when Bricker described the ileal conduit. The complications were instrumental in dissuading many urologist. A clinical observation on 14 cases of ureterosigmoidostomy was made on who had been admitted to the Department of urology from January, 1976 to march, 1985. Use of the combined procedure seems to minimize the incidence of pyelonephritis, and the incidence of hypercchloremic acidosis as a long-term complication appears to be an acceptable problem. Ureterosigmoidostomy should be considered more frequently as the method of urinary diversion.

Chondrocytes isolated from the articular cartilage of rabbit knee joint were cultured in vitro within fibrin glue carrier for 2 weeks. Histochemical and electromicroscopical approaches were used to study chondrocytes behavior and phenotypic expression. In vitro study, chondrocyte assumed a rounded morphology, accumulated metachromatic matrix and took on the cytological characteristics of in vivo cartilage cells. Allogenic cultured chondrocyte in fibrin glue was transplanted into osteochondral defect in rabbit joint. The contralateral knee joint served as a control in which the defect was left empty. This in vivo study was performed for the investigation of the chondrogenic potential of cultured chondrocytes embedded in fibrin glue. Grafted defects was filled with cartilage in gross finding, repaired tissue consisted of differentiated chondrocytes and matrix resumed that of hyaline cartilage. At sixteen week after transplantation, subchondral region was partially transformed into bone without loss of overlying articular cartilage, but in control group, defect did not heal successfully. Repaired articular cartilage was thicker than host cartilage and tide mark was not shown up to 24 weeks. Some of repaired tissue was degraded partially. These results suggest that fibrin glue provides suitable environment for differentiation of chondrocyte and allograft of cultured chondrocyte in fibrin glue transplanted into large osteochondral defect improves cartilage repair.

graft as a successful procedure that provides functional stabiIity. Complications reported include arthro5brosis, patellofemoral joint pain, patellar tendinitis, patellar tendon rupture, recurrent laxity, posterolateral instabi5ty, medial subluxation of the patella, chronic knee pain and painful neuroma. Among them, anterior knee pain was the rnost frequent eomplication. Authors performed arthroscopy assisted one tunnel technique for reconsction of the ACL using autogenous Bone Patellar tendon-Rone (BPTB) in 87 patients. Patients were divid@d into two groups based on the harvested side (knee) of the BPTB. Group 1 consisted of 45 cases of ipsilateral side and group 2 consisted of 42 cases of contralsteral side in harvesting the BPTB. The patients were foll4wed up for at least 12 months to determine whether using the BPTB harvested from the contralateral knee wguld reduce the anterior knee pain at the ACL reconstructed knee. Althaugh there were no statistically signifiqant differences between group 1 and 2 with regard to anterior knee pain, the prevalence of the anterior knee pain was less frequent in group 2 than group 1. This study showed that using the contralateral side harvested autogenous patellar tendon would be a possible protector for anterior knee pain and assists for early rehabilitation.

Dryness has harmful effect on the harvested autogenous bone. But there was no report how the bone cells response to the drying condition and recuperate after exposure. Cytotoxic effect of dryness on the osteoblast-like cells were examined from 18- day chick calvaria. The cells were rinsed with lactated Ringer solution or lactated Ringer solution with 10% fetal bovine serum to see whether the added serum could help the cells live longer. Cultured cells were exposed to room air for period of time ranging from 0 minute to 35 minutes and viability was determined using the MTT test. Cultured cell death increased with the increase of exposure time to air between 25 and 30 minutes. No live cells existed after 35 minutes exposure. Lactated Ringers solution containing 10% fetal bovine serum did not prolong the survival time of osteoblast-like cells compared with lactated Ringers solution alone. These results suggest that the drying of bone cells that occurs in the operating room, especially after a prolonged reconstructive procedure, may severely damage the cell viability of exposed bone or grafted bone and thereby compromise the fusion rate.
