Deformities of the leg and ankle may result from growth abnormalities of the tibia and fibula. The appearance of the secondary ossification center and growth plate closure of the tibial and fibular epiphyses, and the pattern of closure of the epiphyses, were observed in a different age. Normal radiographs were reviewed in one hundred and fifty patients at age from two days after birth to 20 years, who were injured on the contralateral leg, at Wonju Medical College, Yonsei University from Feb., 1980 to May, 1984. The results were as follows: 1. The time of the appearance of secondary ossification center and the closure of growth plates; The proximal tibial epiphysis usually forms secondary ossification center at birth to second postnatal months, the physeal closure occurs from 13 year and 11 months to 18 year 3 months in male, from 13 year 4 months to 15 year 5 months in female. The secondary ossification center of the distal tibial epiphysis appears from 8th postnatal months to one year, and physeal closure occurs from 15 years to 17 year and 4 months in male, from 15 year 2 months to 16 year 8 months in female. The secondary ossification center of the tibial tuberosity appears from 9 year 3month to 12 year 2 months, and closure occurs from 16 year 3 months to 18 year 7 months inmale, from 14 year 10 months to 19 year 1 months in female. The proximal fibular epiphysis forms secondary ossification center from 2 year 5 months to 5 year 4 months, closure occurs from 15year 8 months to 17 year 4 months in male, from 14 year 9 months to 16 year 9 months in female. The secondary ossification center of the distal fibular epiphysis appears from 2 year 5 months to 3rd years, and closure occurs from 13 year 11 months to 17 year 6 months in male, from 13 year 4 months to 16 year 7 months in female. 2. The growth and the pattern of the closure of growth plates of the tibia; The proximal tibial epiphysis is elliptic for the first 3 years of life. The epiphysis is slightly conical centrally as it extends toward the tibial spines, and becomes more prominent from 8 years to adolescence. The closure of the proximal tibial growth plate occurs initially along the anteromedial aspect of the tibia and tibial tuberosity during 12 years and proceeds posterolaterally. Complete closure of the proximal tibial physis occurs about from 13 years to 18 years. The secondary ossification center of the distal tibial epiphysis is oval in shape initially, becomes thicken medially by 3rd year of life, then the tibial plafond is valgoid, and becomes horizontal at age 10 approximately. The distal epiphysis of tibia unites first at about 13 years, starting centrally and proceeding toward anteromedial portion. And the posterolateral portion unites finally by about 15 to 17 years. The tibial tuberosity develops a secondary ossification center by 7 to 9 years, usually in the most distal region, and gradually elongates and extends toward the secondary ossification center of the proximal tibia.From about 12 years, the tuberosity epiphyseal center fuses with the proximal tibial center, and the fusion with the tibial metaphysis extends distally, the tuberosity physis closes completely from about 15 to 19 years. 3. The growth and development of the tibia, fibula and ankle; The growth of the proximal tibial and the distal fibular epiphyses play an important role of the growth rate in lower extremities unber ten years. The distal tibial growth plate inclines laterally and distally prior to the first year of life, the inclination is on the decrease and it finally horizontal at about 12 years. The distal tibia talus angle is about 90° prior to the age one year, becomes mildly valgoid by 12 years.

3.The Development of Viewer of Electronic Medical Vocabulary based on MED: The Viewer of Electronic Medical Vocabulary.
Journal of Korean Society of Medical Informatics 1999;5(3):31-36
OBJECTIVE: To Implement Effective Vocabulary Viewer for Electronic Medical Vocabulary Database Such as MED. DESIGN: A few Medical Vocabulary Database access method are reviewed. Some of their disadvantage of acquiring specific medical concepts are identified. MED has chosen as an example Medical Vocabulary System. We studied AccessMED, a vocabulary browser that supports lexical matching and the traversal of hierarchical and semantic links, and enhanced methodology of medical vocabulary browsing and acquiring medical vocabulary. RESULTS: The paper suggests platform independent client-server architecture Medical Vocabulary Viewer, MEDUSA. Additional support for Medical Vocabulary Browsing options such as display all ancestor, multiple concepts displaying, and bookmarking workspaces are implemented. CONCLUSION: Since MEDUSA uses client-server architecture along with scripting language such as TCL/TK as implementation language, it runs multiple platform. We claim MEDUSA can be easily integrated with other Medical Vocabulary such as UMLS. Using bookmark and annotation function of MEDUSA enables many vocabulary developers from multiple sites to communicate and discuss new concepts better.

Neurofibroma, one of the peripheral nerve tumor, is a complex benign tumor arising from skin, deep soft tissue, nerve tissue and bone. The incidence of peripheral nerve tumor is relatively low and it may occur either solitarily or diffusely. Plexiform neurofibroma, a type of neurofibroma, develops characteristically in the patients with von Recklinghausen's disease and its exact incidence is unknown. The case reports of solitary plexiform neurofibroma not associated with von Recklinghausen's disease were extremely rare. We reported a case of solitary plexiform neurofibroma on the median nerve.

We conducted this cohort analytic study to determine whether women with unexplained elevations of maternal serum hCG at 15-18 weeks' gestation are at increased risk for pregnancy complications and adverse perinatal outcomes. The inclusion criteria were a singleton gestation, a confirmed gestational age, and an hCG level greater than 2.0 multiples of the median (MoM). The exclusion criteria were fetal anomalies, an abnormal karyotype, molar pregnancy, and an MSAFP level greater than 2.5 multiples of the median (MoM). A group of randomly selected women with hCG levels under 2.0 MoM served as controls. Patients with elevated levels of hCG had a significantly higher risk for PIH (17.9% versus 4.5%; P <.05) and preterm delivery (17.9% versus 3.5%; P<, 05) than control. But no significant differences were observed in the incidence of intrauterine growth restriction and low birth weight and in the newborn weight. We suggested that pregnancies with unexplained elevated hCG levels should be regarded as high-risk pregnancies. And these patients require careful monitoring with adequate obstetric management.

PURPOSE: The aim for this study was to investigate clinical manifestation of seasonal influenza A and B during the 2012 winter season in Wonju, South Korea. Their clinical and laboratorial characteristics and effect of oseltamivir were compared and analyzed. METHODS: Children under the age of 18 years who visited the Wonju Severance Christian Hospital with fever or acute respiratory symptoms and who were diagnosed with influenza A or B by rapid antigen test from nasopharyngeal swab were selected for the study. The medical records of patients were retrospectively reviewed. RESULTS: Influenza A was detected in 374 patients (83.7%), and influenza B in 72 (16.6%). The incidence of influenza A was highest in February (n=186), while that of influenza B was highest in March (n=36). The most common symptoms were fever (n=434, 97.1%) and cough (n=362, 81.0%). No significant differences were observed between influenza A and B in symptoms and laboratory data. Patients who had used oseltamivir within 2 days showed statistically lower admission rate, shorter admission duration, and lower incidence of pneumonia. CONCLUSION: This study found no statistical difference between influenza A and B, in symptoms, progression, and laboratory test, but those who were treated with oseltamivir given within 2 days of the onset of fever experienced more positive outcomes.

Calcifying aponeurotic fibroma is a very rare benign soft tissue tumor with predilection for the fingers and palms of children and adolescents. We describe an unusual case of a calcifying aponeurotic fibroma in old age that circumferentially involved the dorsal and palmar side of the third metacarpal head.We performed a wide excision using two incisions, resulting in satisfactory clinical result. A calcifying aponeurotic fibroma must be considered in the differential diagnosis of a calcifying soft tissue lesion occuring in the hand of old age.
