2.Quantitative Comparison of Dopa - Positve Cells in the Skin of Normal Person and Pigmentary Disorders.
Korean Journal of Dermatology 1985;23(5):590-596
Melanocytes were identified by the dopa reaction, and counted in vertical sections of 183 specimens of normal skin and 218 specimens of patients with pigmentary disorders. The incidence of dopa-positive cells in the basal layer was determined. One cell in 9 in the basal layer was dopa-positive in normal specimens. There was no significant difference in the incidence of dopa-positive cells between male and female and between adult and children. Specimens from face, neck and prepuce revealed comparatively high incidence of dopa-positive cells. Among pigmentary disorders, vitiligo and halo area of halo nevus were characterized by an abscence or marked reduction in the number of dopa-positive cells, but lentigo and cafe-au-lait spot were characterized by an increase in their number In tuberous sclerosis, tinea versicolor and idiopathic guttate hypomelanosis, there wasn't any change of the melanocyte population between lesional skin and normal skin. The significance of these findings in vertical skin sections was discussed.

PURPOSE: Laparoscopic cholecystectomy has become the standard modality of acute and chronic gallbladder disease. This study was performed to evaluate a change in the indication for laparoscopic cholecystectomy according to period by analyzing our experiences. METHODS: We retrospectively analyzed 2,096 cases of laparoscopic cholecystectomy that were treated at the Department of Surgery, Dong-A University. They were divided into 3 groups from October 1992 to December 1996 (Group 1), from January 1997 to December 2001 (Group 2) and from January 2002 to March 2007 (Group 3). RESULTS: The mean age was 50.14+/-13.89 years and the male-to-female ratio was 1 : 1.23. Previous abdominal surgery was noted in 12.24% from Group 1, 14.96% from Group 2 and 21.48% from Group 3. Chronic cholecystitis was the most common pathologic diagnosis in all cases. However, while the incidence of acute cholecystitis and gallbladder empyema in Group 1 was 3.36% and 0%, that of Group 2 was 12.52% and 3.88% and that of Group 3 was 31.79% and 7.59%, which was increased. The mean operation time of each group was 101.00+/-51.00, 69.86+/-40.55, 78.01+/-45.55 minutes (P<0.05). The conversion rate of each group was nine cases (6.04%), 21 cases (3.02%), and 51 cases (4.07%). The surgical complication rate was 7.38%, 3.88% and 4.71%, respectively. The length of hospital stay was 6.08+/-3.65, 3.16+/-2.99 and 2.91+/-3.34 days, which was significantly decreased (P<0.05). CONCLUSION: As surgical experience increased and laparoscopic surgical skills developed, the indication for laparoscopic cholecystectomy changed. The results of this study showed that laparoscopic cholecystectomy was feasible for the treatment of complicated gallbladder lesion.

Nevus lipomatosus cutaneous superficialis(NLCB) is a rare condition consisting of ectopic fat tissue in the dermis and having the predilection for the pelvic girdle, especially gluteal region. The patient was a 20 year-old female. About 8 years prior to the first visit she had noticed the rice-sized papules on her lower back, which had been gradually increased in size and coalesced to become two, cerebriform, skin colored to yellowish tumor masses of soft consistency, distributed on both sides of the midline of lower back, and measuring respectively 3.5X7.Qcm and 7.0x11.5cm in size. Jihe biopsy specimen taken from the tumor mass revealed the ectopic presence of fat lobules occupying half of the reticular dermis. The fat lobules consisted of almost mature fat cells with the presence of dilated capillaries in their centers.

8.Chiari Osteotomy in Old Congenital Dislocation of the Hip

Twelve neglected congenital dislocations of the hip in ten patients over the age of eight years were treated by open reduction and chiari osteotomy. Reduction was aided by preoperative traction only in two hips, by femoral shortening with preoperative traction in three and by femoral shortening only in seven. The average follow up period in our series is 3 years, ranging from 1 year and 2 moths to 4 years and 5 months. The overall results were good but one case of avascular necrcsis and one case of redislocation were seen. By our experience it is thought that all old and congenitally dislocated hip in the growing age can be reduced by femoral shortening with soft tissue release, and preoperative traction for its reduction is not undispensable. The most problem in the treatment of the old congenital dislocation of the hip is the postoperative partial ankylosis in the affected hip and this problem would be overcome by delicate operative technique and meticulous hemostasis.

The estimated incidence of duodenal Crohn,s disease ranges from 0.5-4% of the patients with Crohn,s disease. However, isolated involvement of Crohn,s disease in the duodenum is very rare, and most duodenal Crohn's disease is accompanied with it elsewhere in the gastrointestinal tract. As clinical, radiographic, and endoscopic features may overlap with those of peptic ulcer disease, patients presenting with isolated duodenal involvement may be perplexing diagnostically. The initial treatment for duodenal Crohn,s diease is medical, but if complications such as gastric outlet obstrution, intractable pain during medical therapy, or hemorrhage occur, surgical intervention is necessary. We experienced one case of isolated duodenal Crohn,s disease showing gastric outlet obstruction without any lesion elsewhere in the gastrointestinal tract and report the case with a review of the literature.
