PURPOSE: In contracted bladder of various etiologies, if many of conservative managements fail, a surgical treatment seems to be the only therapeutic approach. We tried to evaluate the long term results of aug mentation cystoplasty including the postoperative complication and the degree of satisfaction in patients. MATERIALS AND METHODS: From 1989 to 1988, augmentation cystoplasties had been performed in 11 patients with contracted bladder of various etiologies. We reviewed the patients' medical records including the result of urodynamic examinations, retrospectively. Postoperative follow-up periods were 9 to 114months (mean:61months). Patients were interviewed by telephone. RESULTS: Urinary frequency, nocturia, dysuria and suprapubic pain were improved in all patients, but dysuria persisted in one patient with tuberculous cystitis. Clean intermittent catheterization (CIC) was done in there of 11 patients due to large volume of residual urine. The volume of residual urine was 200-300ml in one with hyperreflexic neurogenic bladder, and 100-200ml in two with interstitial cystitis. Self voiding was possible in 8 patients with residual urine volume less than 90ml. Almost all patients were very satisfied symptomatically in the telephone survey. There were no significant complications which required surgical revision. CONCLUSIONS: It is concluded that augmentation cystoplasty could be an excellent method of treatment for selective patients with contracted bladder, who have not improved symtomatically by medication or conservative management.

STATEMENT OF PROBLEM: Second-generation indirect composite resins have been improved flexural strength, compressive strength, hydrolytic degradation resistance, wear resistance compared to first-generation indirect composite resins, but there are still some problems as hydrolysis and low wear resistance. Some manufacturers claim that wear resistance of their materials has been improved, but little independent study has been published on wear properties of these materials and the properties specified in the advertising materials are largely derived from in-house or contracted testing. PURPOSE: This study was to evaluate the wear of indirect composite resins (SR Adoro, Sinfony, Tescera ATL) and gold alloy against the human enamel. MATERIAL AND METHOD: Extracted human incisors and premolars were sectioned to 2*2*2mm cube and embedded in the clear resin and formed conical shaped antagonist to fit the jig of pinon-disk tribometer. Total 20 antagonists were stored in distilled water. Five disk samples, 24mm in diameter and 1.5mm thick, were made for each of three groups of indirect composite resins and gold alloy group, and polished to #2,000 SiC paper on auto-polishing machine. Disk specimens were tested for wear against enamel antagonists. Wear test were conducted in distilled water using a pin-on-disk tribometer under condition (sliding speed 200rpm, contact load 24N, sliding distance 160m). The wear of the enamel was determined by weighing the enamel antagonist before and after test, and the weight was converted to volumes by average density. The wear tracks were analyzed by scanning electron microscopy and surface profilometer to elucidate the wear mechanisms. Statistical analysis of the enamel wear volume, wear track depth and wear tract width of disk specimens were accomplished with one-way ANOVA and the means were compared for significant differences with Scheffe's test. RESULTS: 1. The enamel wear was most in gold alloy, but there were no statistically significant differences among all the groups (P>.05). 2. In indirect composite resin groups, the group to make the most shallow depth of wear tract was Sinfony, followed by Tescera ATL, SR Adoro (P<.05). Gold alloy was shallower than Sinfony, but there was no statistically significant difference between Sinfony and gold alloy (P>.05). 3. The width of wear tract of SR Adoro was larger than the other groups (P<.05), and there were no statistically significant differences among the other groups (P>.05). 4. SEM analysis revealed that Sinfony and gold alloy showed less wear scars after test, Tescera ATL showed more wear scars and SR Adoro showed the most. CONCLUSION: Within the limits of this study, Sinfony and gold alloy showed the least wear rates and showed similar wear patterns.

We report a rescently experienced case with atypical radiologic manifestation of solid and papillary epithelial neoplasm of the pancreas in a 37 years old female patient. The tumor had heavy calcification on its capsule wall and septa. Instead of the usual encapsulated lesion with partly solid and partly cystic-hemorrhagic components, the lesion consisted of numerous fine cavitations containing air without fluid component except focal abscess fluid.

PURPOSE: To report the first case of Waardenburg syndrome type 4 in Korea. CASE SUMMARY: A 3-year-old boy visited our clinic to have his abnormal right eye iris color checked. The patient had a previous operation Hirschsprung's disease. In addition, his older sister and aunt showed similar ocular findings. A general physical examination, hearing test, and fundus examination were performed. On examination, hypochromic heterochromic iridum, albinism of the posterior pole upon ipsilateral fundus, and dystopia canthorum were found. There was no abnormal finding in the hearing test. CONCLUSIONS: The patient showed hypochromic heterochromic iridum, dystopia canthorum, and albinism of ipsilateral fundus. He also had a family history of Waardenburg syndrome and had surgery associated with congenital megacolon. The patient was diagnosed with Waardenburg syndrome type 4.

The incidence of conjoined twins is so rare that few anesthesiologists have an opportunity of managing them. Especially in Korea, there are only a few reports describing the anesthetic management for surgical separation of newborn conjoined twins. We experienced the successful anesthetic management for surgical separation of thoraco-xiphopagus conjoined twins without any particular problems. After applying the noninvasive monitors (ECG, pulse oximeter), one of the twins (twinA) with congenital heart disease was administered with intravenous ketamine for induction of anesthesia and intubated without neuromuscular blocker. Anesthesia was maintained with N2O-O2 and hand ventilation using Mapleson D breathing circuit. After maintaining airway of the twinA, the twinB was intubated and maintained with the same manner. Eighteen days after the separation procedure, the twinA with congenital heart disease died and the other one, twinB has been alive with normal growth and development.
