We have performed three total wrist arthroplasty of Meuli type on the dominant wrist of three female patients who have been suffering from the classical rheumatoid arthritis for more than two years, and after follow them for average twenty months postoperatively, we have found, even the complications and reoperation rate after total wrist arthroplasty are reported high in literature, three patients have reasonably satisfied with the remarkable relief of pain and the functional abilities of their wrists. It is our belief, even if the total wrist arthroplasty is also still in controversy, that in those patients with bilateral wrist involvement by the rheumatoid arthritis in whom arthrodesis was done on one wrist, then a total wrist arthroplasty on dominant wrist is a most prefer way to reconstruct the disabled wrists.

Gastric volvulus is a rare surgical disorder in the pediatric population. We experienced a case of gastric volvulus. A 2-year-old boy was admitted to hospital with abdominal distension. An upper gastrointestinal series showed reversal of the greater and lesser curvatures. Surgical exploration revealed an organoaxial volvulus of the stomach, and anterior gastropexy was performed.

We are calling the erupting ground water as drug water or mineral water in Korea and thinking those water and food making water. Authors tried to investigate the evidence of contamination by user on the 10 erupting ground water and gained following results: 1. All of the mineral waters on 10 area in Seoul were unfittable to drinking water standard. 2. In the view of the bacteriology 80% were contaminated by coliform group. 3. The highest value of the free carbon dioxide contents were 652.96 ppm at Sam Sun Mineral Water.

Three-dimensional (3D) structure of the bronchopulmonary segments should be understood for accurate diagnosis and treatment of lung diseases. Two-dimensional (2D) tools (e.g. anatomy books) or traditional 3D tools (e.g. plastic models) are not sufficient for understanding 3D structure of the bronchopulmonary segments. The lung of a cadaver may not always be available for dissection, when it is needed. To overcome this problem, virtual dissection programs of the lung have been made. However, most programs include either 2D images that do not permit free dissection or radiographs that do not reveal true color and have limited resolution, and cannot represent 3D structure of the bronchopulmonary segments. Moreover, it is necessary to make a virtual dissection program of each race and ethnic group. Thus, we attempted to make a 3D image and virtual dissection program of the lung using a Korean cadaver in order to help medical students and doctors better understand 3D structure of the bronchopulmonary segments. One pair of lungs was extracted from a Korean male cadaver. Dye with specific color was injected into each segmental bronchus to distinguish bronchopulmonary segments. The lungs were embedded with gelatin solution, and serially-sectioned with 1 mm- thickness using a meat slicer. Sectioned specimens from each lung were inputted into the computer using a scanner (300 X 400 resolution, true color). 2D images of the lungs were aligned on the alignment program which was composed using IDL language. In 2D images, the bronchopulmonary segments were manually segmented by help of dye. 3D images of the bronchopulmonary segments were reconstructed through the volume-based rendering of 2D images. With 3D images as the main features, the virtual dissection program of the bronchopulmonary segments was composed using IDL language. Various virtual dissection functions, such as sectioning a lung at free angles to show its plane, identifying the bronchopulmonary segments represented in the sectioned plane, and rotating the selected bronchopulmonary segments at free angles, were established. This virtual dissection program of the bronchopulmonary segments is helpful in better understanding 3D location and shape of the bronchopulmonary segments; it is expected to be used through CD-title or Internet as an educational tool for medical students and doctors.

A 29 year old woman with unresectable leiomyosarcoma of the inferior vena cave extending into the right atrium of the heart was presented. The upper and middle inferior vena cava involved and there were both intrinsic and extrinsic tumor growth components. The diagnosis was made by a combination of radiological studies including ultrasound, CT, inferior vena cavography and arteriography and the diagnosis was confirmed by ultrasound guided rumor biopsy. The clinical and radiological presenting features were reviewed.
