A case of very rare synovial hemangioma of the right knee joint is presented. The duration of disease is for fifteen years. A hemangioma about 6X7X1cm in dimension has been found to be originated from lateral capsular synovium just above lateral meniscus and just anterior to lateral collateral ligament. The joint space was occupied with pedunculated mass. The complete excision could be done. The end result is good.

The disease Blount called tibia vara in 1937, is characterized by a failure of growth localized to the postero-medial part of the upper tibial metaphysis and epiphysis. The growth of the epiphyseal cartilage as well as that of the metaphysis and the epiphysis is disturbed, with consequent angulation of the tibia at the upper epiphysis which may, in untreated cases, produce bizarre deformities. Blount described two different types of tibia vara, an infantile type and an adolescent type. Presenting case is an adolescent type. He is 11 year old boy. The deformed tibia is corrected by osteotomy.

OBJECTIVE: The aim of this study is to present the basic reference data of age and sex specific gait parameters for Korean adults. METHOD: The basic gait parameters were extracted from 70 healthy adults, 38 men and 32women, 21 to 69 years of age using VICON 340 Motion Analyzer. RESULTS: The temporal gait parameters and kinematic parameters of Korean adults were similar to other western reference data. CONCLUSION: Significant sex differences exist in the maximal pelvic tilting, pelvic internal rotation and foot internal rotation and plantar flexion. There is a statistically significant age variability for the hip and knee flexion at stance phase.

PURPOSE: Rodent models that mimic human renal diseases are being increasingly recognized as powerful tools in the development of new drugs and for evaluating the efficacy of novel therapeutics in a preclinical setting. However, there are few reports on microvasculature imaging of the urinary system in small animals. An experimental study was performed to evaluate the microvasculature in a rat kidney using micro- computed tomography(CT) with three-dimensional images. MATERIALS AND METHODS: Five Sprague-Dawley male rats(age: 10-12 weeks, weight: 200-250g) underwent a laparotomy under anesthesia with an intramuscular injection of 0.5cc xylazine hydrochloride and ketamine mixed solution(1:10). After ligation of the abdominal aorta and inferior vena cava immediately above the renal artery, a 24 gazed catheter was inserted into the abdominal aorta. A physiological solution and heparin(500U) were infused through the catheter to flush the blood from the renal vasculature. The kidney was enhanced using self-made contrast material. The excised kidney was frozen for the micro-CT scan. RESULTS: The mean longitudinal diameter and weight of the 10 resected kidneys was 1.95+/-0.15cm and 2.0+/-0.28g, respectively. The images were represented by three-dimensional arrays of cubic voxels with opacities in the blood vessels. In the section taken from the arrays, four regions of the kidney could be identified easily by their characteristic vascular features. CONCLUSIONS: Micro-CT is a promising method for evaluating the renal microvascular architecture in a rat kidney. It can for the foundation of an experimental study aimed at providing quantitative information on the urinary system in a rodent model.

Diabetic muscle infarction (DMI), also known as diabetic myonecrosis, is a rare complication of diabetes mellitus (DM); hence, it is often underdiagnosed. Thus, timely diagnosis and treatment are essential for a better prognosis. We describe a 24-year-old woman with Prader-Willi syndrome and an 8-year history of uncontrolled type 2 DM, who presented with a sudden onset of fever and subacute painful swelling of her left thigh. She was finally diagnosed with DMI based on magnetic resonance imaging and muscle biopsy after excluding other infectious and inflammatory diseases of proximal muscles. The patient was treated with bed rest, strict glycemic control, and analgesics, and her symptoms gradually resolved. DMI should be considered in the differential diagnosis of patients with poorly controlled DM, who present with subacute pain and swelling of lower extremity muscles, without a history of trauma.

PURPOSE: We evaluated the safety and feasibility of transperitoneal laparoscopic upper pole heminephrectomy (TLUHN) in pediatric patients by comparing an age-matched cohort undergoing open upper pole heminephrectomy (OUHN) by a single surgeon. MATERIALS AND METHODS: A total of 10 OUHNs were performed between 1995 and 2003 and 10 TLUHNs between 2003 and 2008. The 10 patients in each group were matched by age (p=0.94), gender (p=1.0), and body weight (p=0.91). RESULTS: There was no open conversion in the TLUHN group. The median operative time in the TLUHN and OUHN groups was 174 minutes (range, 98-205) and 190 minutes (range, 120-258), respectively (p=0.19). In the TLUHN and OUHN groups, the median blood loss was 25 ml (range, 20-30) and 35 ml (range, 20-100) (p=0.74), the median analgesic requirement was 0 hours (range, 0-42) and 0 hours (range, 0-87) (p=0.16), and the median hospital stay was 5.5 days (range, 3-7) and 7 days (range, 3-19) (p=0.01), respectively. There were no intraoperative complications in either group. Postoperative atelectasis occurred in two and five patients in the TLUHN and OUHN groups, respectively. Similar results were found in the subanalysis of patients younger than 24 months. CONCLUSIONS: TLUHN is safe and feasible even in small children and infants. Furthermore, decreased hospital stay is the main advantage of the laparoscopic approach compared with open surgery.

BACKGROUND AND OBJECTIVES: We investigated in patients with coronary vasospastic angina whether the exercise ECG test results are influenced by the different modes of exercise load and compared the clinical characteristics including coronary risk factors between patients with positive and negative exercise tests. MATERIALS AND METHODS: This study comprised 34 patients with documented coronary artery spasm without significant stenosis (coronary artery luminal diameter narrowing <70%) and treadmill exercise test. Treadmill exercise ECG test was performed based on Bruce's protocol (graded exercise test, GET) and sudden rapid exercise protocol (non-graded exercise test, NGET) in the morning of the same day. RESULTS: 1) Of 29 patients who underwent both GET and NGET, 19 patients manifested positive result by NGET, whereas only 11 patients did by GET (66 vs. 38%, P=0.04). All patients with positive GET had positive NGET and 8 of 18 patients with negative GET had positive NGET. 2) Of 34 patients who underwent GET, there was no significant difference in frequency of hypertension, diabetes, current smoking, presence of effort chest pain by history, mixed disease (fixed stenosis >50%, <70% of luminal diameter) or total cholesterol level between patients with positive and negative results. In 18 typical variant angina patients by clinical history, 8 of 10 patients with high disease activity (5 times or more attack per week) manifested positive result by GET or NGET, whereas 4 of 8 patients with low disease activity (80 vs. 50%, P=NS). CONCLUSION: In patients with coronary vasospastic angina, sudden rapid exercise could induce more frequently coronary artery spasm than multistage exercise. The result of an exercise test may not be correlated with coronary risk factors, coronary anatomy, effort chest pain, and the disease activity.
