  • Pachydermodactyly is a rare distinct form of fibromatosis characterized by acquired, asymptomatic dense fibrosis and fibroblastic proliferation around one or more proximal interphalangeal joints. Intralesional triamcinolone injection may be helpful in improving the clinical appearance. A 20-year-old unemployed female patient gave a four years history of progressive swelling of the fingers affecting predominantly the proximal interphalangeal joints of index fingers of left hand and index, middle fingers of right hand. There was no pain and tenderness. Physical examination, complete blood count, antinuclear antibody, rheumatoid factor were unremarkable and radiograph of both hands showed soft tissue swelling only without bony abnormality. We excised the redundant soft tissue from the both sides of proximal interphalangeal joint with longitudinal elliptical fashion. After operation, the fingers of the patient showed marked improvement cosmetically. There were no motor or sensory changes. Pachydermodactyly was first reported in 1996 in Korea. Histologic features include an increased dermal accumulation of collagen and occasionally an increased number of fibroblast. We report for one patient with pachydermodactyly treated with longitudinal elliptical excision and obtained an improvement of clinical appearance.

  • The regional distribution and relative frequency of endocrine cells in the alimentary tract of the snake, Rhabdophis tigrinus tigrinus, were investigated by immunohistochemical method using 7 antisera. Chromogranin (Cg)-, glucagon-, somatostatin-, gastrin/cholecystokinin (Gas/CCK)-, serotonin-, bovine pancreatic polypeptide (BPP)-immunoreactive cells were identified in this study. Cg-immunoreactive cells were detected throughout the alimentary tract including the esophagus, with predominant frequency in the pylorus. Numerous immunoreactive cells were observed from the esophagus to the pylorus but a few cells were detected in the large intestine. Glucagon-immunoreactive cells were observed from the proximal portions to the distal portions of the small intestine. They were increased to the middle portions but thereafter decreased, and no cells were found in the terminal portions. Somatostatin-immunoreactive cells were restricted to the small intestine and these cells were decreased toward to distal portions of the small intestine. Gas/CCK-immunoreactive cells were detected in the pylorus and small intestine. They were most predominant in the pylorus and the proximal portions of the small intestine but thereafter decreased toward to the distal regions. Serotonin-immunoreactive cells were observed throughout the alimentary tract. They were most predominant in the pylorus and proximal portions of the small intestine but a few cells were observed in the large intestine. BPP-immunoreactive cells were restricted to the distal portions of the small intestine with rare frequency. No bombesin-immunoreactive cells were found in this study.

  • Background : The purpose of the present study was to evaluate the direct and indirect composite restorations which had been placed for 1 year Methods : The composite restorations which had been placed between 1999. Mar and 1999, Dec was evaluated after 1 year For direct restorations. Spectrum (Dentsply, USA) and Z100 (3M, USA) were used in the anterior teeth and Surefil (Dentsply, USA) were used. For class V restorations of anterior and posterior teeth. Spectrum was used. For indirect restorations, Targis/Vectris system (Vivadent/Ivoclar, Liechtenstein) was used 2 examiners evaluated marginal quality, proximal contact. discoloration, presence of 2$^{nd}$ caries, loss of filling and hypersensitivity of restorations. The restorations was clinically evaluated by modified methods based on USPHS. Results : 60 teeth were evaluated. 59 were clinically acceptable and 1 restoration which was placed in class v cavity in the posterior tooth was fallen out. In most cases, the restorations were clinically accept-able. For restorations which had been directly placed in the class II cavities, loose proximal contact was indicated as the main complaints. Conclusions : Most of Anterior and posterior restorations which bad been directly or indirectly placed for 1 year were clinically acceptable. For posterior teeth, loose proximal contact was indicated as the main problem in the directly placed Class II restorations. Long term clinical study is needed.

  • Purpose : To compare the diagnostic accuracy of proximal caries detection between Kodak Insight film and the Biomedisys CDX2000HQ digital (CCD) sensor. Materials and Methods: 156 proximal surfaces of extracted teeth, 78 of which had chemical artificial caries, were used in this study. Four observers interpreted the radiographs using a five-point confidence rating scale to record their diagnoses. The results were analyzed by receiver operating characteristic curves, ANOVA and Kappa values. Result: Analysis using receiver operating characteristic curves revealed the areas under each curve which indicated a diagnostic accuracy of 0.951 in Insight and 0.952 in CDX2000HQ digital sensor. ANOVA revealed no significant differences between the two images with respect to caries detection. Kappa values indicated that the mean intra-observer agreement was 0.85 and inter-observer agreement 0.71 in conventional radiography. In digital radiography, the mean intra-observer agreement was 0.84 and inter-observer agreement 0.72. Conclusion: The results suggest that no significant difference exists between the two modalities for artificial caries detection and that CDX2000HQ was as good as Insight film for this purpose.

  • Esophageal atresia with double tracheoesophageal fistula is a very rare anomaly and is difficulty to diagnose preoperatively. We treated a full term baby with esophageal atresia with double tracheoesophageal fistula. At the first operation, only the distal tracheoesophageal fistula was identified and ligated. When the upper esophageal pouch was opened, intermittent air leakages in sequence with positive bagging were noticed. However, intraoperative bronchoscopy did not identify a fistula in the proximal pouch, and the operation was completed with end to end anastomosis of the esophagus. On the $7^{th}$ postoperative day, esophagography showed another tracheoesophageal fistula proximal to the esophageal anastomosis. A wire was placed in the fistula preoperatively under bronchoscopy. At the 2nd operation through the same thoracotomy incision the proximal fistula was identified and ligated. On the $12^{th}$ postoperative day, esophagography showed neither stricture nor leakage.

  • The purpose of this paper was to investigate the significance of splinted and non-splinted implant-supported restorations with an internal connection for multiple consecutively missing teeth. Upon examination of the effects of fixture-abutment connection, the distribution of occlusal load was favorable in splinted implant-prosthesis with an external connection, but effect of strain distribution was not significant in splinted implant-prosthesis with an internal connection. In splinted implant-prostheses for short implants, strain distribution was not affected by the method of retention. For cement-retained prostheses, the effect of strain distribution due to splinting was not significant. In clinical studies, non-splinted prostheses with an internal connection for multiple consecutively missing teeth showed high survival rate, mild marginal bone loss, and stable periodontal condition. However, failure to achieve optimal proximal contact between single-unit prostheses may lead to food impaction, and veneer fracture may be inevitable when the framework provides inadequate support in the proximal region. In conclusion, splinted implant-prosthesis is not an indication in all cases, and clinical consideration of its use should be based on the patient's oral condition, such as location and number of implants, formation of proximal contact, canine guidance, existence of parafunctional habit, and oral hygiene, when multiple consecutively missing teeth are replaced by internal connection type implant.

  • Thymocyte-specific transcriptional regulatory systems can be used to better understand the relationship between transcription and V(D)J recombination during early T cell development. In this study, we generated transgenic mice expressing the transactivator Gal4-VP16 or the Gal4 DNA binding domain (Gal4-DBD) under the control of the lck proximal promoter, which is only active in immature thymocytes. From these studies Gal4-VP16 and Gal4-DBD expression was shown to significantly alter thymic cellularity and differentiation without significantly changing the $CD3^+$ thymocyte distribution. Furthermore, the presence of Gal4-VP16 or Gal4-DBD in the transgenic thymocytes retarded the mobility of the Gal4 DNA binding motif as determined by a gel mobility shift assay, suggesting that the developmental alteration did not affect the functional property of the transgenic proteins. These results indicated that lck promoter-driven Gal4-VP16 or Gal4-DBD expression did not affect $CD3^+$ mature thymocytes, thus this system can be applied to study transcriptional regulation of transresponder genes in bigenic mouse model thymocytes.

  • The combination of congenital stapes fixation and proximal symphalangism has been described in several kindreds. It exhibits autosomal dominant inheritance. A patient, 11-year-old female, visited department of otolaryngology of SNUH in December, 1980. Her complaint was bilateral hearing loss since birth. Physical examination revealed fusion of proximal interphalangeal joints of both 4th and 5th fingers. Tympanic membrane was normal. Temporal bone X-ray was normal. Pure tone audiogram revealed about 60 dB conductive loss with horizontal curve. On exploratory tympanotomy of right side, bony fixation of stapedial footplate was found. So, stapedectomy with connective tissue wire prosthesis was performed. As a result, marked improvement of hearing was obtained with 5 dB A-B gap on operated side.

  • We reported a case of chondrosarcoma in proximal tibia in a 44-year-old man. MR images demonstrated a $3.5{\times}20$ cm sized bone tumor. In reconstruction of resected proximal tibia, we used the allograft bone and soft tissue defects were covered by medial gastrocnemius rotation flap and skin graft. There were no local recurrence and distant metastasis and any complication such as secondary infection, nonunion, metal failure at the time of the last follow-up. There was no limitation of knee motion through the appropriate rehabilitaion programs.

  • Giant cell-rich osteosarcoma is a rare tumor that is hard to distinguish from giant cell tumors of bone. The location and radiographic aspect of these tumors can be identical. The histologic differentiation between a giant cell-rich osteosarcoma and a giant cell tumor can be difficult. Due to the different prognosis and treatment strategies of these tumors it is essential to make the right diagnosis at presentation. This article reports a case of a giant cell-rich osteosarcoma of the proximal tibia that initially was diagnosed histologically as a giant cell tumor by needle biopsy.
