PURPOSE: In this retrospective study, we attempted to evaluate the treatment outcome and the prognostic factors of thymoma treated with surgery, radiotherapy and chemotherapy. METHODS AND MATERIALS: Between 1979 and 1998, 55 patients with thymoma were treated at the Seoul National University Hospital. Of these, 11 patients underwent surgery only, 33 patients received postoperative radiotherapy and 11 patients received radiotherapy only. Twenty-three patients had gross total resection and 21 patients subtotal resection. For postoperative radiotherapy, the radiation dose consisted of 41.4-55.8 Gy. The average follow-up was 64 months, and ranged from 2 to 160 months. The sex ratio was 1:1 and the median age was 48 years (15-74 years). Overall survival and disease-free survival were determined via the Kaplan-Meier method, and the log-rank was employed to evaluate for differences in prognostic factor. RESULTS: The five- and 10-year survival rates were 87% and 65% respectively, and the median survival was 103 months. By univariate analysis, only stage ( p=0.0017) turned out to be significant prognostic factors of overall survival. Also, stage ( p=0.0007) was significantly predictive for overall survival in mutivariated analysis. CONCLUSION: This study showed the stage was found to be important prognostic factors, which influenced survival. Especially, as incomplete resection is related with poor results, complete resection is important to cure the invasive thymoma.

BACKGROUND: Basal cell carcinoma(BCC) is the commonest type of skin malignacy, and its incidence is increasing. As a result, the number of cases requiring treatment by dermatologists may also be increasing. OBJECTIVE: The aim of this study was to clarify the presentation pattern of BCC and to assessce the surgical treatment used in the dermatological surgery clinics in Seoul National University Hospital and Seoul City Boramae Hosptial between 1994 to 1998. METHOD: We reviewed the medical records and checked clinical aspects and surgical treatment methods. RESULTS: The Total number of patients was 33. There were 21 Females and 12 males. The Mean age was 63.1. The most common anatomical site was the face and scalp(30 cases, 91%). The mean size of the tumor was 12.2 by 9.6 mm. BCCs were removed by complete surgical excision with a normal skin margin of 2 to 4 mm. The local flap was most commonly used to repair surgical wounds (55%) and primary closure was used in 39% of patients. A Pedicle flap and full thickness skin graft were also used in surgical defect reconstruction. CONCLUSION: With increasing public awareness and earlier presentation there may be a reduction in tumor size at the time of diagnosis. As most BCCs are found on the head and neck and are usually more or less than 1cm in diameter, it is thought that appropriate education of surgical skills should be needed and offered.

PURPOSE: To re-evaluate the morphological and functional recovery of conservative treatment of major renal injuries. MATERIALS AND METHODS: We reviewed 68 patients admitted at our hospital due to major renal injury from Jan. 1991 to Dec. 1996. 33 of the 68 patients(48.5 percent) could be managed conservatively without surgery, All patients underwent follow-up abdominal CT and 12 of the 33 patients underwent DMSA renal scan at more than 3 months after injury. RESULTS: The mean function of the injured kidneys in comparison with contralateral kidney was 88.3 percent in case of normal finding in follow-up abdominal CT scan. CONCLUSIONS: We concluded that DMSA renal scan would be the valuable study for evaluation of the functional recovery of major renal injury.

The taxonomy of Acanthamoeba spp., an amphizoic amoeba which causes granulomatous amoebic encephalitis and chronic amoebic keratitis, has been revised many times. The taxonomic validity of some species has yet to be assessed. In this paper, we analyzed the morphological characteristics, nuclear 18s rDNA and mitochondrial 16s rDNA sequences and the Mt DNA RFLP of the type strains of four Acanthamoeba species, which had been previously designated as A. divionensis, A. parasidionensis, A. mauritaniensis, and A. rhysodes. The four isolates revealed characteristic group II morphology. They exhibited 18S rDNA sequence differences of 0.2-1.1% with each other, but more than 2% difference from the other compared reference strains. Four isolates formed a different clade from that of A. castellanii Castellani and the other strains in morphological group II on the phylogenetic tree. In light of these results, A. paradivionensis, A. divionensis, and A. mauritaniensis should be regarded as synonyms for A. rhysodes.

A turret exostosis is a rare complication of minor trauma to the dorsum of the fingers. In 1966, Wissinger reported first and called turret exostosis. Until now any case have not been reported in Korea. A twenty year-old man complained a painful mass on dorsum of the middle phalanx of the left 4th finger. Thirteen months ago, he had deep laceration of the left 4th finger and extensor tendon was ruptured totally with dorsal cortical breakage of the middle phalanx. Radiologically, there is a smooth, dome shaped, and well-defined osseous mass fused to the underlying bony cortex on the earlier injury site. This is a finding that suggest turret exostosis. We report a case and a brief review of literature.
