PURPOSE: H. pylori infection was recently reported to be associated with unexplained iron-deficiency anemia(IDA) in children and adolescents. H. pylori-related IDA was thought to occur due to GI blood loss, scavenging of iron by H. pylori and iron malabsorption. The aim of this study was to examine how the status of H. pylori infection and age of children affected RBC indices, serum iron level and TIBC. METHODS: We performed esophagogastroduodenoscopy, and examined RBC indices, serum iron and TIBC on 178 pediatric patients with recurrent abdominal pain. H. pylori infection was assessed by CLO test and silver stain of gastric biopsy specimen. RESULTS: H. pylori infection was found in 42 of 178 patients(23.6%). In children with H. pylori infection, the prevalence of iron deficiency(ID) and IDA(39.0% and 10.3%, respectively) was higher than in children without H. pylori infection(29.6% and 4.1%, respectively), but there was no statistically significant difference. Serum iron level was lower(69.5+/-32.7 vs 77.3+/-34.1g/dL; P= 0.08) and TIBC was higher(380.8+/-50.4 vs 366.9+/-47.0g/dL; P=0.09) in children with H. pylori infection than in children without H. pylori infection. All RBC indices and iron saturation were lower in children with H. pylori infection than in children without H. pylori infection, but there was no significant difference between the two groups. In correlation analysis, serum iron, Hgb, Hct, MCV and MCH were significantly increased by age in children without H. pylori infection (P<0.05), but MCH and MCHC were decreased significantly(P<0.05) by age in children with H. pylori infection. In multiple regression analysis, the change of serum iron, MCH and MCHC by age was significantly influenced by the status of H. pylori infection(P<0.05). CONCLUSION: H. pylori infection decreases RBC indices and serum iron and increases TIBC in children. These changes become prominent as age increases. This age effect rnay be related to the duration of H. pylori infection. (J Korean Pediatr Soc 2000;43:755-762)

Injuries and pains of musculoskeletal joint in human body is common onset in industrialized world. However, muscle fatigue plays a very significant role in contributing causes of many pains associated with musculoskeletal joints. Based on this hypothesis, degree of muscle fatigue was investigated using electromyography measurement technique during isometric and concentric/eccentric muscle contractions. Different response of the muscle fatigue between two different muscle contractions (isometric and concentric/eccentric contractions) was examined by comparison of parameters which were median frequency, median power and RMS value. Healthy 16 young persons without previous musculoskeletal diesease history were tested with Noraxon Myosystem 2000 EMG measurement system. In this study, two different exercises were performed. First exercise was concentric/eccentric exercise. Second exercise was isometric muscle contraction. In the case of the isometric exercise, median frequency was decreased, but median power and RMS were increased. However, during the concentric/eccentric exercse, median frequency was increased, but median power and RMS were decreased. Both of those revealed that the pattern of the median frequency was W type, but median power and RMS were M type as time passed. In this study, the patterns of the muscle fatigue during concentric/eccentric exercise as well as isometric exercise were identified. It will be helpful to prevent musculoskeletal injury from over-working andexercising.

The present study was intended to examine the spectrum of radiographic patterns of the stomach associated withacute and chronic pancreatitis and their complications. Subjects served for the study consisted of 70 cases ofpancreatitis (36 cases in acute stage and 34 cases in chronic stage). Intramural and perigastic permeation ofextravasated pancreatic enzymes and secondary inflammatory reacation that follows are responsible for theardiographic change observed. 1. Generalized rugal thickening and particularly selective mucosal prominences ingreater curvature of body and antrum are characteristically seen in acute(14 of 36 cases

Synthetic hydroxyapatite is a safe, nontoxic, biocompatible, and osteoconductive material. Hydroxyapatite-coated implants have the property of achieving a very strong bond with living bone in a relatively short period. From March 1992 to June 1994, 140 hydroxyapatite-coated primary total hip prostheses were implanted. This study included 60 cases that could follow up minimum 3 years. At the time of mean follow up, 45 months after operation, the mean Harris hip score was 92 points. Only two patients complained of thigh pain at last follow up. On radiographic evaluation, radiolucent lines were seen around the uncoated distal part of the stem in 46 percents of the implants. No radiolucent line was observed around the coated area of the prosthesis. Cancellous condensation was seen in 95 per cents of the implants at the Gruen zone 2 and 6 area. Cortical hypertrophy was present in 32 percents. Fourteen cases had the gaps at the bone to acetabular cup interface in the immediate postoperative period. The gaps disappeared in 12 months after operation. Five implants were revised because of polyethylene wear, cup migration and periprosthetic fracture. The clinical outcome was excellent. But this result was obtained in the relatively short-term follow up. Longer-term data will be the only true test of the value of hydroxyapatite coated implant.

Microsurgery offers a more effective approach to the brachial plexus lesions than any treatments previously available. The authors have performed operation to the injured plexus by microsurgical techniques since 1980. We selected 15 patients whom we could follow more than one year and had results as follow. 1. The causes of injuries were traffic accident(7 cases), gun-shot injury(4 cases), stab wound(3cases), and belt injury (1 case). 2. Two patients had preganglionic lesion and 13 patients had postganglionic lesions, among which seven cases were supraclavicular and six cases were infraclavicular. Most frequently injured site was in upper two roots and upper trunk (7 cases). 3. All of them were treated by surgical intervention, 12 cases by interfascicular nerve graft using autogenous sural nerve, one case by intercostal neurotization, one case by neurolysis, and one case by exploration only. 4. Elbow flexor and deltoideus were involved easily by injury than other muscles, but they had best prognosis to the microsurgical treatment. 5. The recovery of wrist and finger function was poor but they were frequently preserved from injury.

Femoral head and neck fractures during the course of avascular necrosis are rare with only few reports in the English literature. Moreover, there are very few reports on an analysis of the patterns of these fractures. Four cases of femoral head fracture caused by minor trauma, which were quite different from the crescent fractures during the course of avascular necrosis were analyzed in regard to the underlying disease, causes, sites, types, directions, pattern of fractures and the injury mechanism of the fractures. The results are reported with special regard to the pattern of the stress fracture of the femoral head and neck during the course of avascular necrosis.

The Acquired Immunodeficiency Syndrome(AIDS) is defined as a reliably diagnosed disease that is at least moderately indicative of an underlying cellular immunodeficiency in a person who has no known cause of underlying cellular immunodeficiency. The AIDS is caused by the human T-lymphotropic virus type III. We report here on a 32-year-old Korean male with AIDS. Detailed ophthalmic examinations were done and several cottonwool spots were found in both eyes. Other ocular findings of AIDS were not seen in this patient.
