The Ilizarov technique for gradual distraction osteogenesis was developed in the 1950s. A correctly performed osteotomy is essential to the success of distraction osteogenesis and prepares for limb lengthening. Between Sept. of 1991 and 1994, thirty-four patients were treated by Ilizarov technique at St. Benedict Hosp. and Gang-Dong Hosp.. And then assigned to two separate groups : a corticotomy group (group A) and osteotomy group (group B; osteotomy with Gigli saw or osteotomy with multiple drill holes and osteotome). The regenerate segments were evaluated weekly for the first six weeks after operation. After the initial six-week evaluation period, observations of these segments were continued through a series of monthly radiographs. Distraction began on postoperative day seven in group A and on day eleven in group B; and continued at a rate of 1 mm/day and a frequency of 4 times/day. Group A displayed new bone formation earlier than group B: group A's mean was 16.5 ± 4.9 days, while B's mean was 25.3 ± 4.6 days. The first bridging callus occurred earlier in group A than it did in group B: A's mean was time of 36.7 ± 9.9 days, while B's mean was 44.0 ± 7.9 days. There was no significant difference between groups A & B in terms of first cortical formation : A's mean was 86.9 ± 24.0 days, and B's mean was 100.6 ± 25.2 days. There was no significant difference between groups A & B in terms of the bone healing index : A's mean was 41.6 ± 13.5 days and B's mean was 41.15 ± 8.10 days.

Fetal bilateral renal agenesis is a lethal congenital anomaly. An early and reliable prenatal diagnosis is extremely important as it may offer options for pregnancy termination as early as possible. The criteria for the ultrasonographic diagnosis of bilateral renal agenesis are severe oligohydramnios, nonvisualization of the bladder, and the empty renal fossa. However, severe oligohydramnios makes it difficult to diagnose the disease because of poor sonographic resolution. We present two cases of bilateral renal agenesis, one is diagnosed by ultrasonography after amnioinfusion at 24 weeks gestation, the other is diagnosed postnatally after term delivery.

The general consensus of the treatment for ankle fracture is anatomical reduction and restoration of the distal tibiofibular relationship. In general, stabilization of the disrupted syndesmosis may be achieved by repairing ruptured ligament; fixing associated fractures of the fibular, avulsed tubercles, and medial malleolus; or by placing a screw between the tibia and the fibular to hold the syndesmosis in position until some degree of syndesmotic ligament healing can occur. However, the managements of syndesmosis remain controversial. The purpose of this study is to evaluate the effect of the syndesmotic fixation in the ankle fractures. The patients with syndesmotic disrupted ankle fracture, who were treated operatively between 1990 and 1995 at St. Benedict Hospital, were divided into the two groups based on whether trans-syndesmotic screw was used or not. The group I included 42 ankle fractures that were treated with trans-syndesmotic screw, while the group II included 28 ankle fractures that were treated without syndesmotic screw. The results obtained from this study were as follows. 1). There was no significant difference of the clinical result between the two groups. 2).When the diastasis was satisfactorily reduced after rigid, anatomic medial and lateral fixation, syndesmotic screw fixation was not required to maintain the integrity of the tibiofibular joint.

PURPOSE: To compare clinical characteristics of ganglions in hand & Foot. MATERIALS AND METHODS: Seventeen cases of ganglions located in foot and fifty-five cases in hand. Excised from Mar.1988 to Apr.2003, were included in the study. The clinical characteristics and recurrence ratio were evaluated RESULTS: The mean size of 2.2 cm in hand and 2.5 cm in foot. The most common area of ganglions are dorsum of foot and wrist. The cosmetic problem of palpable mass is the primary chief complaint of ganglions on hand and the pain is that of foot. The recurrence was found in 5 cases in hand and 4 cases in foot. The recurrence was related to incomplete excision of ganglion in foot and the large size of ganglion and incomplete excision of ganglion in hand. CONCLUSION: recurrence ratio in the cases of foot is higher than that of hand. The ganglions in foot and hand need to treated by meticulous surgical excision to prevent the recurrence.

In order to observe the influence of halothane upon the blood pressure during general anesthesia, the author prepared a formula, expressing change of blood pressure by times series and analyzed the types and distribution patterns in this experiment. The results obtained were as follows: 1) Blood pressure was high at the time of intubation. 2) Generally, blood pressure increased at the time of intubation and then stabilized within 20 minutes. 3) Most common patterns were dentified. (ijEE) type was 73~74% that is most common type, and (iEEE) type was 40~44%.

Recent studies have reported that obsessive-compulsive (OC) symptoms are highly prevalent in schizophrenia, and schizophrenic patients with OC symptoms have a poorer clinical course compared to those without OC symptoms. In spite of many previous case reports, treatment of OC symptoms in schizophrenia has not been systematically studied. We report a patient with chronic schizophrenia who had obsessive symptoms such as bizarre, stereotyped behaviors. Treatment with olanzapine and risperidone, resulted in partial response for his psychotic symptoms, respectively. The obsessive symptoms, however, persisted and fluoxetine was added to the risperidone regimen. After 4 weeks of combination treatment, fluoxetine was titrated up to 80 mg/day and his obsessive symptoms became less in frequency and intensity. After 7 weeks on combination treatment of risperidone and fluoxetine, obsessive symptoms resulted in a significant reduction. On the 20 months of following, he remained in a recovered state and had been treated with risperidone 4 mg/day, and fluoxetine 20 mg/day.

PURPOSE: To evaluate the results of surgical treatment and relationship between the recurrence and characteristics of ganglions in foot and ankle. MATHERIALS AND METHODS: Seventeen cases of ganglions located in foot and ankle, excised at St. Benedict Hospital from Mar. 1993 to Apr. 2003, were included in the study. All of cases were analyzed retrospectively in terms of age, sex of the patients, location and size of the ganglion, symptom, operative method as well as recurrence rate were evaluated. The mean follow up was 1.8 years (11 months~6.5 years). RESULTS: The size of ganglion ranged from 0.5 cm to 5.0 cm with mean size of 2.5 cm. The most common area of ganglion was the dorsum of foot and pain was the primary chief complain The recurrence was found in 4 cases (23.5%): 1 of them occurred among 8 cases the diameter of which was less the 2.5cm and other 3 occurred among 9 casees larger than 2.5cm. 12 cases were completely excised mass with no recurrence. But 5 cases were incompletely excised & ligated stalk of mass and 4 cases of them were recurred. A correlation was only observed between complete excision and low recurrence rate. CONCLUSION: Recurrence rate of ganglions in foot and ankle was high and the correlation was obstained between complete excision and low recurrence rate.

BACKGROUND: From a pharmacokinetic standpoint, middle ear effusion (MEE) acts as a sequestered compartment since diffusion of antibiotics from serum and to this compartment is limited. The effectiveness of an antibiotic to eradicate infection within an anatomic compartment is related to both its ability to penetrate and the susceptibility of the causative pathogen. OBJECTIVE: The goal of this study was to determine the steady state plasma and MEE concentrations of cefprozil in pediatric chronic otitis media with effusion (COME). MATERIALS AND METHODS: Twenty-five children with COME were enrolled, and MEE was collected using a ventilation tube insertion after 0.5, 2, 3, 5, and 6 hours of single oral administration of 15 mg Cefprozil/kg body weight. Blood samples were also collected as soon as the MEE was collected, and analyzed in order to measure the concentration of Cefprozil using the validated high performance liquid chromatography (HPLC) method. RESULTS: The mean concentrations of cefprozil in MEE ranged from 0.4 to 4.4 ug/ml. The penetration of cefprozil into the MEE was rapid and effectively. Cefprozil in the MEE was maintained at a greater level than MIC90 in Streptococcus pneumoniae for at least 6 hours after administration of 15mg/kg. CONCLUSION: Cefprozil penetrates well into MEE in patients with pediatric COME.
