PURPOSE: This study was undertaken to evaluate the clinical results of pars plana vitrectomy on posterior segment complications in posterior uveitis. METHODS: We reviewed the records of 20 eyes of 19 uveitis patients who were followed up for 6 months or more after vitrectomy. RESULTS: The mean follow-up period was 20 months. Final visual acuity improved in 10 eyes (50%), was maintained in 6 (30%), and decreased in 4 (20%). The mean improvement of vision was 1.6 lines (p=0.019). Detached retina was reattached in 8 (80%) among the 10 eyes with primary surgery. Postoperative complications were cataract (7 eyes), macular degeneration (2 eyes), retinal detachment (2 eyes), and recurrence (1 eye). CONCLUSIONS: These results suggest that pars plana vitrectomy may be a safe and effective treatment for posterior segment complications in posterior uveitis, but that early and complete vitrectomy should be considered for a better visual prognosis.

PURPOSE: This study was done to analyze survivals, patterns of failure, and complications of early uterine cervix cancer after curative radiotherapy. METHODS AND MATERIALS: Eighty patients with uterine cervix cancer FIGO Stage IB (48 cases) and Stage IIA (32 cases) treated with radiotherapy were analyzed retrospectively. Patients were treated from November 1985 to May 1993, and minimum follow up period was 24 months. and 6 cases were lost to follow up. All of them were treated with external radiotherapy and different fractions of high dose rate intracavitary radiotherapy. Survival rates, failure patterns, complication rates and degrees of severity were analyzed according to several factors. RESULTS: Overall 5 year survival rate and relapse free survival rate were 72.3%, and 72.8% respectively. Prognostic factors were stage, size, pathology, RT response and there was no significant survival difference among the reasons of radiotherapy choice. There were 19 cases of treatment failure, another 3 cases were not tumor related death, and most of treatment related failure occurred within 24 months. Late complication rate of bladder and rectum were 8.8%, 15% respectively, frequency and severity of complication were correlated with ICR fractionation dose and total dose. CONCLUSION: These results showed that survival rates of early stage radiation treated cervix cancer patients were comparable to surgical series, but more aggressive treatment methods needed for stage IIA poor prognostic patients, To decrease late complication, choice of proper ICR dose and meticulous vaginal packing is needed.

BACKGROUND/AIMS: Gastric carcinoma is the most common malignant neoplasm in Korea and is known to be associated with intestinal metaplasia (IM) of gastric epithelium, of which type III IM is suggested to play a special role in the carcinogenesis. This study is to evaluate the subtypes of IM and to measure each subtype in chronic gastritis. Methods: From October 1997 to September 1999, 321 patients with endoscopic chronic gastritis were evaluated the grade of chronic gastritis and IM by histologic and histochemical stain. RESULTS: Chronic inflammation and IM were remarkably severe in men and Helicobacter pylori (H. pylori) positivity was 69.4% in men and 65.2% in women. The frequency of IM was 50.1%, of which 65.4% was in men and 34.6% in women. The frequency of IM subtypes was 43.2%, 11.7% and 45.1% for type I, II and III respectively. Sixty percent of IM was noted in more than 50 years of age and ninety percent in more than 40 years of age. The frequency of type III IM was 61.6% in men and 38.4% in women. Sixty one percent of type III IM was noted in more than 50 years of age and ninety percent in more than 40 years of age. Interestingly, fifty three percent of type III IM was noted in men more than 40 years of age. The prevalence of H. pylori infection in type III IM was similar to in type I and II. The glandular atrophy in type III IM was remarkably severe than that in type I and II. Conclusions: The results of this study show that the proportion of type III IM in chronic gastiritis is remarkably high in Korean and age and sex distribution is similar to that of gastric carcinoma.

The result of artificial skins made with collagen is poor after grafting over the full thickness wounds due to their rapid degradation by enzymatic cleavage. This study is an in vivo study of an artificial skin made with a biodegradable polymer, which can better address the problem of the collagenous artificial dermis. To investigate the availability of a biodegradable polymer for an artificial dermis and to get an information about the optimal degradation rate of a polymer for an artificial dermis, we made an artificial dermis by seeding of fibroblasts within the vicryl mesh and made a bilayer artificial skin by covering the artificial dermis with cultured keratinocytes. And these artificial dermis and artificial skin were evaluated in a full thickness wound model. The results are as followings: 1. The artificial dermis was available for grafting for 1 week culture of vicryl mesh-fibroblast. 2. The artificial dermis retarded the contraction of full thickness wounds. 3. The artificial dermis generated the granulation tissue and accepted the STSG completely. 4. The generated tissue from the artificial dermis had incorporated into the surrounding tissue by 4 weeks postgrafting. 5. Vicryl in the artificial dermis became to biodegrade from the culture period and absorbed completely by 5 weeks. 6. The epidermal portion was poorly differntiated during in vitro culture period. In conclusion, the polymer-fibroblast graft can retard the wound contraction and generate a new tissue permitting a useful dermal replacement. And to get more optimal results, another polymer which has slower biodegradation rate than vicryl should be used for the artificial dermis and the epidermal portion should be differentiated after in vivo grafting.

Patients who had posterior synechiae associated with uveitis,IOL mplantation, vitrectomy, underwent Nd-YAG synechiolysis had been treated with topical corticosteroids and surgical iridectomy. Even minimal dilatation of the pupil by Nd YAG synechiolysis enable the patient to read and the surgeon to postpone cataract surgery and evaluate optic disc or fundus. Also, pupil block may be treated by detaching the synechiae.18 Patients (20 eyes) with posterior synechiae underwent Nd-YAG synechiolysis at Kangnam St.Mary's Hospital from November 1997 to August 1998. An average of 17.14 +/-6.43mJ laser were used. The average prelaser pupil size was 3.78 +/-0.98 mm ;postlaser, 5.13 +/-1.27 mm.This change was statistically significant (p<0.01). Microhyphema and pigment dispersion developed in 4 eyes. However,no significant long-term complications occurred, and there were no obvious lenticular damage and pupil abnormality. Because this laser treatment is relatively safe and offers some possibility of visual improvement, we recom-mend Nd-YAG synechiolysis,but only if performed by an experienced laser microsurgeon.

Five cases of histologically proven polymorphic reticulosis were examined with computed tomography(CT). CT findings were mucosal thickening along the septal and lateral walls of the nasal cavities(n=4), obliteration of the contour of the nasopharynx(n=4), involvement of the paranasal sinuses (n=2), destruction of the nasal septum and/or sinus walls(n=3) and mass in the palate, tonsil or neck (n=1). CT examination was helpful in determining the extent of the disease in the nasal cavity and paranasal sinuses. However, lesions in the palate and tonsils could not be easily evaluated with CT. CT findings of polymorphic reticulosis are nonspecific and granulomatous diseases may show similar CT findings.
