We report two cases of recurrent extramarnmary Pagets disease after wide local excision. Both cases involved the scrotum and the penoserotal junction, respectively. On histopathological examination, we could observed many Paget cells confined to the epidermis and the hair follicle, but not invading the underlying dermis in both cases. There was no evidence of internal malignancy. Both cases were treated with wide local reexcision.

BACKGROUND: Recent evidences suggest that anesthetic action within the spinal cord is important in suppressing somatic responses to painful stimuli. Intrathecal endothelin-1 (ET-1) is known to have antinociceptive effect. The purpose of this experiment was to determine whether intrathecal ET-1 may influence the minimum alveolar concentration (MAC) of isoflurane in rats and access the role of the spinal cord as the sites of anesthetic action in blocking somatic responsiveness. METHODS: In Sprague-Dawley rats fitted with an indwelling intrathecal catheter, we determined the MAC of isoflurane using a tail-clamp technique as a painful stimulus, combined with end-tidal anesthetic sampling. In experiment 1, the control MAC was determined and changes of control MAC were observed after intrathecal ET-1 (4x10-2 nmol, 4x10-3 nmol) administration. In experiment 2, we observed the effects of L or N type Ca++ channel blocker such as verapamil (50 g) or W-conotoxin (0.5 g) on the MAC after measurement of the control MAC. In experiment 3, after measurement of the control MAC, ET-1 (10-2 nmol) was administered intrathecally and the MAC was determined again. Next, intrathecal verapamil (50 g) or W-conotoxin (0.5 g) was injected. After that, the MAC was determined again. RESULTS: In experiment 1, ET-1 decreased the MAC of isoflurane and its effect was sustained over 2 hours. In experiment 2, the MAC, determined following administration of verapamil or W-conotoxin, was not different from that of the control. In experiment 3, the MAC was decreased after ET-1 administration and then increased following injection of verapamil or W-conotoxin. CONCLUSIONS: These results suggested that ET-1, in relation to calcium, might play an important role in determining the MAC of isoflurane in the spinal cord.

LPS and IFN-r induce nitric oxide synthase in macrophages and the resultant NO causes apoptotic cell death in the activated macrophages. NO production and apoptosis were inhibited by N-monomethyl L-arginine (NMMA), a competitive inhibitor of NO synthase. To study the role of BCL-X proteins, RAW 264.7 cells were transfected with the expression vectors with human bcl-Xl or bcl-Xs cDNAs, respectively. Stable transfectants were selected and confirmed by RT-PCR. NO production in response to LPS and IFN-r caused apoptosis in RAW 264.7 cells and vector transfected control cells within 24 hr. Both NO production and apoptosis were inhibited by N(G)-monomethyl L-arginine (NMMA). In contrast, bcl-Xs transfectant appeared slightly susceptible and bcl-X(L)< transfectant appeared slightly resistant, although NO production was similar to control cells. These results suggest that bcl-X proteins play roles in both positive and negative regulation of apoptosis induced by NO.

Leiomyoma of the urethra is a rare entity. We experienced a case of leiomyoma in the female urethra recently. Twenty-eight-year-old multiparous woman admitted to the Department of Urology, Busan National University Hospital with the chief complaint of a painless mass on the anterior lip of the external urethral meatus. The mass was easily removed by electroresection. It was an ovoid mass, 3.0 x 2.0 x 2.0 cm in size, and was firm and well-encapsulated. Histologically it was confirmed as a benign leiomyoma.

Intradural schwannoma accompanied with torsion is rare. Intradural lumbar schwannoma was found in a 63-year-old man presenting with right sacral pain radiating to the lower extremity. This mass showed minimal enhancement on MRI. The tumor's location changed each time on MRI and CT-myelography. The patient underwent surgical resection and the cauda equina, linked to this schwannoma, was severely twisted.

BACKGROUNDS: Reflux esophagitis has been known to be a frequent complication after a total gastrectomy. Reflux esophagitis is very annoying to the patients, so various types of reconstructions has been introduced to eliminate this complication. METHODS: This study is a retrospective clinical analysis of 34 patients with gastric cancer who were treated with a total gastrectomy from January 1989 to December 1997 at the Department of Surgery, Seoul Adventist Hospital. RESULTS: During 9 years, the operation was performed on 194 patients with gastric cancer, amomg which 34 (17.3%) were total gastrectomies. The peak age was in the 5th and the 6th decades (58.8%), and the sex ratio of males to females was 1.6:1. The sites of the stomach cancer were the cardia (C) in 10 cases (29.4%), the body (M) in 19 cases (55.9%), and the cardia and body in 5 cases (14.7%). The TNM classification was stage I in 15.6% of the cases, stage II in 15.6% of the cases, stage III in 62.5% of the cases, and stage IV in 6.3% of the cases. Three methods of alimentary tract reconstruction were used:a loop esophagojejunostomy with a Braun anastomosis (27), a Roux-en-Y esophagojejunostomy (6), and an uncut Roux procedure (1). The reflux esophagitis rates for patients treated with a loop esophagojejunostomy with a Braun anastomosis and for patients treated with a Roux-en-Y esophagojejunostomy were 25.9% and 16.7%, respectively. The perioperative mortality was 5.8%, and the causes of death were pneumonia and anastomotic leakage. The most common recurrent site was the anastomotic site. CONCLUSIONS: Reflux esophagitis developed more often after a loop esophagojejunostomy with a Braun anastomosis than after a Roux-en-Y anastomosis. This finding was not significant statistically. Thus, further study of more cases is needed.

We attempted to investigate the effects of curricular change on a basic medical science, anatomy, based on academic achievements including Basic Medical Education Examination (BMEE). We performed an analysis between the academic years of 2011 and 2012. Independent-samples t-test for the academic achievements, paired-samples t-test for the promotion, and correlation analysis for the related subcategory of the anatomy based on the results of BMEE, which was done with SPSS 22.0. In this follow-up study for two academic years, the academic achievements decreased as the students went to the next grade under the changed curriculum of anatomy. The academic achievements decreased as the students went to the next grade in the academic year 2012 while it increased in 2011 (p<0.01). Although averages of school evaluations were similar between the academic years, the academic achievements were different from each other: it was higher in first BMEE for 2012, and in second BMEE for 2011 (p<0.05). Although the correlation was not found among school evaluations, first and second BMEE of 2011, the associations were seen both between school evaluations (p<0.01) and each BMEE (p<0.05), respectively, in 2012. These results suggested that professors of medical school should continue to lead the direction of the curriculum improvement and management depending on the academic achievement, and also to monitor all the processes, maintaining a quality of the assessment system although it might be difficult to be representative or generalize for all medial schools.
