Cutaneous metastasis of the papillary thyroid carcinoma(PTC) is very rare. We report a case of PTC that metastasized to the left fourth fingertip. Its cutaneous appearance was similar to granuloma pyogenicum. A 65-year-old woman who has PTC with regional lymph nodes involvement and pulmonary metastasis complained of a protruding hemorrhagic subungual mass on the left fourth finger for two months. The histopathologic findings showed papillary projections of the tumor cells surrounding the axial fibrovascular stroma and mitotic cells. The tumor cells showed a positive reaction with antithyroglobulin antibody in immunoperoxidase stain. To the best of our knowledge, this is the first case report of PTC that metastasized to the fingertip, and that showed granuloma pyogenicum-like cutaneous lesion at the metastatic site.

The surgical technique of renal transplantation has been well established, but surgical complications are not uncommon and still be important factors in postoperative mortality and morbidity. From August 1990 to May 1998, we performed 250 consecutive renal transplantations at Maryknoll hospital. The authors analyzed the kinds and incidences of surgical complications in a single center by using information from hospital records. The results were as follows: 1. The overall surgical complication rate was 9.6% (24 episodes in 250 cases). 2. These were composed of 6 vascular, 8 urologic, 4 lymphatic, and 6 wound complications. 3. Vascular complication included renal artery stenosis in 1 case and bleeding and hematoma in 5 cases. 4. Urologic complication included urine leakage in 4 cases, ureter stenosis in 2 cases and bladder stone in 2 cases. 5. Lymphatic complication was all lymphoceles. 6. One case in which renal artery stenosis had occured progressed to graft loss after 4 years later. There was no complication related mortality. 7. 1 year, 3 year and 5 year graft survival rate was 97.2%, 94.8% and 90.0%, respectively. and patient survival rate was 98.0%, 95.6% and 94.7%, respectively.

Productivity analysis of physician is one of essential factors for the optimal health manpower planning. Among 690 physicians operating clinic and registered on the Kyeongsangnamdo Medical Association, 623 physicians were studied with a structural questionnaire from April 1 to May 31, 1990. This study covers the general characteristics and productivity of physicians and attempts to find relevant determinants of their productivity through stepwise multiple regression analysis based on collected data. The major results were as follows. First, physicians were more prevalent 35~44 group (38.2%) in age, male (95.8%) in sex, specialist (76.5%) in specialization, city (78.0%) in geographical location. Age group of 35-54 and specialist were more prevalent in cities than in counties, while age group of 25-44 and 55 over and general practitioner in counties (p<0.001). Second, daily outpatient load of all physician were 77.1 persons on average. Age group of 35~44 had the most outpatient load (90.3 persons) among all age group, 6~10 years group (94.2 persons) in years of duration of practice, 11 hours per day group (83.4 persons) in working hours per day. Specialists had more outpatient load (82.6 persons) than general practitioners (61.1 persons) and physicians in cities had more (80.2 persons) than physicians in counties (66.3 persons). Daily average outpatient load of physicians were significantly different by their age, speciality, number of assistants and years of practice (p<0.001) and working location (p<0.05), but not significantly different by working hours per day of physician (p>0.1). Third, the productivity of physicians operating clinic were significantly affected by the three factorsnumber of assistants of physician, age of physician and duration of practice at the current clinic. Age of physician had negative regression coefficient.

In the treatment of esthetically important areas such as maxillary anterior teeth, they should be corresponded with surrounding tissues, and shape of the smile line, soft tissue, and hard tissue, also the anatomical shape and proportion of the teeth should be considered as well. Esthetic analysis includes facial analysis which evaluates the proper parallelism between the occlusal plane and the horizontal reference line, dentolabial analysis which assesses the position of the incisal edge and the coherence between the occlusal plane and the commissural line, tooth analysis which evaluates not only esthetics but also morphology and appearance for proper function, and gingival analysis which forms ideal outline of gingival margins. A maxillary anterior diastema can be esthetically restored through the systematic diagnostic approach and treatment planning, and orthodontic, prosthetic, and conservative treatment can be applied for the treatment.

Toxic epidermal necrolysis (TEN) is an exfoliative disease of skin and characterized by flaccid bullae and spreading erythema so that the skin has the appearance of being scalded. It results primarily from a toxic reaction to various drugs, but occasionally occurs as a result of infection, neoplastic conditions, or other exposure. Enterovirus 71 (EV 71), the most recently described serotype of the genus Enterovirus (family Picornaviridae), causes a variety of diseases, including aseptic meningitis, encephalitis, poliomyelitis-like paralysis, hand-foot-mouth disease, gastroenteritis, fever and rash. A 3-year-old boy presented at the Department of Pediatrics, Soonchunhyang University Cheonan Hospital due to TEN. There were no definite causes such as drug toxicity, Graft-Versus-Host disease (GVHD) and infection. However, we could have isolated EV 71 from the patient's stool. Until now, there have been no reports showing the relationship between EV 71 and TEN, we report here in a case of TEN-associated with EV 71. Further evaluation is needed to study the relationship of TEN with EV 71.

PURPOSE: The purpose of this study was to examine the academic achievement of the first year medical students at Gachon University of Medicine and Science based on their characteristics (i.e. age, gender, and academic degree types (bachelors/masters), field of major (biology/ non-biology), and admission variables (i.e. MEET, GPA, attitude, interview, and English test). METHODS: The admission scores and demographic information were obtained from 39 students who had entered the university in 2005. T-test was used to examine the differences in academic achievement according to the students' characteristics. Correlations between admission variables and academic achievements were examined while multiple regression analysis was used to decipher the influence of students' characteristics and admission variables on the academic achievements. RESULTS: This study showed that the academic achievements differed significantly depending on degree level, age, and field of study, but not gender. It was also found that both the Nature Science Reasoning (NSR) of MEET subscale score and GPA score correlated significantly with academic achievement in the first year students. Attitude, interview, and English test scores did not correlate significantly. The result of the multiple regression analysis revealed that NSR 1 and 2, field of major, and age accounted for a substantial amount of the variance in academic achievement. CONCLUSION: Students with higher scores in NSR 1 and 2 who majored in biology-related fieldsand who are younger tend to do better academically in their first year of medical school. The results of this study may be helpful to graduate medical schools in designing effective admissions strategies for recruiting students, as well as, in planning the curriculum to improve the academic achievements of medical students.

Traditional removable partial denture is a successful treatment for partial edentulous patients. When the abutment is formed with unilateral minority teeth, satisfaction with the use of removable partial denture may be lowered due to patient's discomfort and damage of the abutment. Recently, it has been reported that the unilateral posterior extension partial denture is used as a bilateral posterior extension partial denture using implant fixed prostheses as abutments. In this case, by using implant surveyed crown prostheses, bilateral posterior extension partial denture is fabricated in site that is predicted to have a poor prognosis. This resulted in improved support, maintenance, and stabilization of the removable partial denture, which were economically beneficial to patient and satisfied with use.

PURPOSE: To analyze stress distribution in premolars restored with inlays or onlays using various materials. MATERIALS AND METHODS: Three-dimensional maxillary premolar models of abutments were designed to include the following: 1) inlay with O cavity (O group), 2) inlay with MO cavity (MO group), 3) inlay with MOD cavity (MOD group), and 4) onlay (ONLAY group). A restoration of each inlay or onlay cavity was simulated using gold alloy, e.max ceramic, or composite resin for restoration. To simulate masticatory forces, a total of 140 N static axial force was applied onto the tooth at the occlusal contact areas. A finite element analysis was performed to predict the magnitude and pattern of stresses generated by occlusal loading. RESULTS: Maximum von Mises stress values generated in the abutment teeth of the ONLAY group were ranged from 26.1 to 26.8 MPa, which were significantly lower than those of inlay groups (O group: 260.3–260.7 MPa; MO group: 252.1–262.4 MPa; MOD group: 281.4–298.8 MPa). Maximum von Mises stresses generated with ceramic, gold, and composite restorations were 280.1, 269.9, and 286.6 MPa, respectively, in the MOD group. They were 252.2, 248.0, 255.1 MPa, respectively, in the ONLAY group. CONCLUSION: The onlay design (ONLAY group) protected tooth structures more effectively than inlay designs (O, MO, and MOD groups). However, stress magnitudes in restorations with various dental materials exhibited no significant difference among groups (O, MO, MOD, ONLAY).

BACKGROUND/AIMS: The aim of this study was to characterize the spectrum of esophageal motor dysfunction after repair of an esophageal atresia with a tracheoesophageal fistula (EATEF). METHODS: This study included 16 patients, aged 0.8 to 13.3 years, who were diagnosed with Gross Type C esophageal atresia and underwent a fistula repair and end to end anastomosis. Esophageal function was evaluated with manometry, 24 hour esophageal pH monitoring, a barium esophagogram, and an endoscopy. RESULTS: Symptoms were present in 8 patients (dysphagia for solid food in 2; frequent vomiting in 6; and poor weight gain in 4). Anastomotic stricture was present in 6 patients. An esophageal manometric study showed that the reflex relaxation of the lower esophageal sphincter (LES) was incomplete or absent in 9 patients (56%). The upper esophageal sphincter (UES) was completely relaxed in all 16 patients. In 14 patients (88%), a normal peristaltic wave was present in the proximal esophagus, but absent below the anastomotic site. Simultaneous contractions were observed in 2 patients (12%). Seven (64%) of 11 patients who underwent 24 hour esophageal pH monitoring presented gastroesophageal reflux. CONCLUSION: Most of the patients after the repair of an EATEF developed motor dysfunction of the esophagus. Poor transmission of the peristaltic waves beyond the anastomotic site and abnormal reflex relaxation of the LES were present.
