The serum creatinine level, excretory urogram, endogenous creatinine clearance value, urine culture and method of drainage of urine of 116 patients with spinal cord injury were examined and compared. The serum creatinine value was found to be poor indicators of renal deterioration in these patients. Combination of bilateral reflux and suprapubic drainage resulted in a greater degree of renal damage, but no reflux with intermittent catheterization group had a good result.

Hemangiopericytoma was first described by Stout & Murray in 1942 and was an uncommon soft tissue tumor thought to be derived from vascular pericytes. Approximately 10-15% of the cases occur in children have a propensity to develop in the region of head, neck and lower extremities. We experienced a case of congenital hemangiopericytoma of small bowel in a male neonate who showed vomiting and abdorninal distension. We reported a case of congenital hemangiopericytoma of small bowel with brief review of related literature.

Xanthogranulnmatous pyelonephritis is an unusual chronic renal infection associated with renal calculi, urinary tract infection or obstruction in many cases. It is characterized by orange-yellow nodules of inflamed parenchymal tissue macroscopically and foamy lipid-laden histiocyte microscopically. We report a case of Xanthogranulomatous pyelonephritis in a 74 years old male.

PURPOSE: To determine follow-up results for elderly patients with osteoporosis that received standard cemented bipolar hemiarthroplasty with double loop and tension band wiring for treatment of unstable intertrochanteric hip fractures. MATERIALS AND METHODS: Between May 2000 and May 2006, 86 cemented bipolar hemiarthroplasties were done in elderly patients who had unstable intertrochanteric fractures. The mean age at the time of surgery was 82 years. The average follow-up period was 5.3 years. We evaluated post-operative results by clinical and radiographic methods. RESULTS: At the final follow-up, the mean Harris hip score was 79.2. The mean time needed for full weight bearing following surgery was 4.2 weeks and 82.5 % of patients regained their preoperative level of ambulation. All patients achieved union in the lesser trochanter fracture, but substantial trochanter displacement was observed in 4 cases. There was one case of acetabular erosion. Superficial infections were found Post-operatively in 2 cases. One case with stem subsidence (<5 mm) showed satisfactory results without subsidence in further follow-ups. CONCLUSION: If cemented bipolar hemiarthroplasty is properly applied in the treatment of unstable intertrochanteric hip fractures in the elderly, systematic postoperative rehabilitation, and pain control can be achieved.

Hyperreactio luteinalis(HL)referes to moderate to marked cystic bilateral enlargement of ovaries due to benign theca lutein cysts, usually related to hydatidiform mole or choriocarcinoma. After its first description by Berger in 1938, almost 53 cases of HL unassociated with trophoblastic disease have been reported in the literature. We encountered one such case in a 34 years old female which was incidentally diagnosed during cesarean section at term.

PURPOSE: This study was aimed at assessing the difference of the prevalence of iron deficiency and iron deficiency anemia among rural and urban middle school students in relation to dietary habit. METHODS: With a questionnaire, blood samples were obtained from 439 apparently healthy rural and urban middle school students residing in Ulsan. Anemia was defined as hemoglobin level of 12.6 g/dL or less for boys and 11.9 g/dL or less for girls. Iron deficiency was defined as serun ferritin level less than 12 micrograms/L or/and transferrin saturation less than 14%. Iron deficiency anemia was defined as iron deficiency plus low hemoglobin. RESULTS: 1) In boys, the prevalence rate of anemia was 17.2%. Among these anemias, 5.4% were found to be iron deficiency anemia. In girls, the prevalence of anemia increased with age. The prevalence of iron deficiency anemia was 6.9%. 2) In girls, the prevalence rate of anemia in rural area was higher than that of anemia in urban area (12.6% in rural, 6.1% in urban, P<0.01). 3) The prevalence of anemia and iron deficiency in the students with menstruation was 10.6% and 33.1%, which was higher than the prevalence of 2.5% and 7.5% in those who did not have the menarche (P<0.001 and P<0.001, respectively). 4) Dietary intake of rural and urban middle school students was estimated lower in energy, iron than the recommeded dietary allowance (RDA). In girls, dietary intake of rural middle school students was estimated lower in iron, niacin, and vitamin C than that of urban middle school students. 5) Nutritional factors such as energy, carbohydrate, protein, and phosphorus showed positive correlation with RBC, hemoglobin (P<0.05). CONCLUSION: It is recommended to enforce the nutritional education to take enough iron in middle school students to reduce the high prevalence rate of anemia among pubertal students.

Thoracopagus is very rare congenital anomaly with an incidence estimated at 1 in 50,000 deliveries or 1 in 600 twin deliveries. If twining is initiated after the embryonic disc and the rudimentary amnionic sac have been formed, and if division of the embryonic disc is incomplete, conjoined twins result. We experienced a case of thoracopagus in 28 years old woman. We present this case with a brief review of literatures.

Osteogenesis imperfecta is a rare congenital disease. It is a heterogeneous group of inherited disorders characterized by multiple bone fracture, blue sclera, hearing loss, abnormalities of dentition and widespread connective tissue ahnormality. We experienced a case of osteogenesis imperfecta diagnosed in utero by ultrasonogram and confirmed hy postnatal radiograph after delivery. We present the case with a hrief review of the literature.

OBJECTIVES: This study was conducted to estimate the incidence rate, and to identify the risk factors for the occupational low back pain among shipyard workers. METHODS: The study subjects consisted of 9,784 workers who were employed in a ship-building industry(excluded workers who had a history of low pack pain before 1995 or did not take periodic health examination in 1995). The cases were 220 people who experienced back pain from January 1, 1996 to December 31, 1998. To assess risk factors for occupational low back pain, Cox propotional hazard model was used. RESULTS: During the recent three years from 1996 to 1998, the incidence rate per 1,000 persons was 7. 8 in 1996, 8. 8 in 1997, and 3. 1 in 1998. The main causes of work-related low back pain were sprain, strain and disc herniation. Lifting was the most common cause of back pain(35. 3%), and carrying(10.2%) and pulling(8.0%) were followed. In Cox proportional harzard model, independent risk factors for back pain were body mass index(R.R.; 1.54, 959o C.I.: 1.06-2.25), shift work(R.R.; 1.65, 95% C.I.: 1.19-2.28), and lifting heavy material(R.R. ; 3.95, 95% C.I: 2.29-6.82). CONCLUSIONS: This study suggests that the risk factors of back pain in shipyard workers were body mass index, shift work and lifting.

STATEMENT OF PROBLEM: In the partially edentulous patients, removable partial dentures have been working as a important treatment modality. Clasps, a kind of direct retainers, received some amount of stresses during the insertion and removal of partial denture on the abutment tooth. PURPOSE: The study is to investigate stresses of the different clasps. MATERIAL AND METHODS: In order to investigate the degree of stresses, maxillary partial edentulism (Kennedy Class II, modification 1) was assumed and removable partial dentures were designed on it with three kinds of metallic materials; cobalt-chromium alloy, type IV gold alloy and commercially pure (c.p.) titanium. Aker's clasp was applied on the left second molar, RPA (mesial rest-proximal plate-Aker's) clasp was on the left first premolar and wrought wire clasp was on the right first premolar. Three dimensional, non-linear, dynamic finite element analysis method was run to solve this process. RESULTS: 1. Cobalt-chromium alloy had the highest von Mises stress value and c.p. titanium had the lowest one irrespective of the types of clasps. 2. In the Aker's clasps, stress on the retentive tips was shown shortly after the appearance of stresses of the middle and minor connector areas. These time lag was much shorter in the RPA clasps than in the Aker's clasp. 3. In general, retentive tips of wrought wire clasps had much less amount of stress than other clasps. CONCLUSION: The amount of stress was the highest in the RPA clasp and the lowest in the wrought wire clasp, in general.
