Purpose: The aim of this study was to evaluate the clinical characteristics, endoscopic findings and risk factors related to the upper gastrointestinal bleeding (UGIB) seen in full-term infants. Methods: A clinical analysis for 9 cases with UGIB confirmed by endoscopy was carried out retrospectively. Patients were admitted to the Department of Pediatrics, Eulji Hospital, from January to December 2003. Results: UGIB from gastric or duodenal mucosal lesions has been seen in 0.13% in newborns infants. All patients were full-term AGA neonates without asphyxic findings at birth. Hematemesis, melena or recurrent vomiting developed within $4.4{\pm}3.8days$ after birth. Vital sign and laboratory test was normal on admission. Endoscopic findings showed hemorrhagic gastritis in 6 cases and peptic ulcers in 3 cases. All patients were successfully managed by medical treatment for $18.6{\pm}5.0days$. On treatment, clinical symptoms improved within $0.9{\pm}0.3days$. Follow-up endoscopy was not performed because there was no recurrence of symptoms in all patients. Case mothers had no history of gastritis, ulcer or anti-ulcer medications before and during pregnancy. Conclusion: If the healthy full-term infants express UGIB within a few days after birth, it is necessary to take careful history of family, mother and delivery process and to practice endoscopy for mucosal lesions of the patients. A follow-up endoscopy dose not seem to be necessary if the infant is clinically well.

The malignant tumor in childhood is one of the main causes of children s death due to disease. The traditional treatment for the malignancy is known for the radiation therapy and the chemical therapy or both. However, the treatments tend to induce intraoral complications. Different from adults, almost all children on cancer therapy are expected to have dental complications, because their permanent teeth are on the developmental stage. The degree of dental complication depends on the patient's age, type of chemical and other factors-radiation dose and frequency. In this report, 3 children who had experienced the anti-cancer therapy on their age between 1 and 4 years were selected and dental complications were examined. The children have chance for the various oral complications including the developmental problems such as agenesis, microdontia and hypoplasia of the teeth. Therefore, it's important to understand the side-effects of anticancer therapy during the permanent teeth had been developmental stage in young patients. Also, oral health care specialists, including pediatric and hospital dentist can support the oncology team by providing basic oral care, implementing oral care protocols, delivering emergency dental treatment undergoing anticancer treatment.

Purpose : This study was conducted to evaluate the red cell indices and frequency of iron deficiency anemia based on the feeding patterns of nine-month-old infants. Methods : Blood tests were performed on 253 nine-month-old infants, who visited Il Sin Christian Hospital for health check-ups from January to December 2007. Their parents answered telephonic questions regarding their feeding patterns and weaning foods. Results : Three infants groups were created according to feeding patterns before they started weaning foods. One group was exclusively breast-fed (48.6%), another had mixed feeding (27.3%), and the third had artificial milk feeding (24.1%). Red cell indices (hemoglobin, hematocrit, MCV, MCH) of the breast-fed group were comparatively lower than those of the other two groups (P<0.05). Twenty-five infants (9.9%) were diagnosed with iron-deficiency anemia. According to feeding patterns, the frequency of anemia was highest in the breast-fed group. Six infants who started weaning foods before six months of age (113 infants) were diagnosed with iron-deficiency anemia (5.3%), and nineteen who started after six months of age (140 infants) were diagnosed with iron-deficiency anemia (13.6%). Conclusion : When nine-month old infants visit hospitals for health check-ups, pediatricians must consider their feeding pattern and weaning foods histories, and then recommend screening blood tests for iron-deficiency anemia.

Purpose: Since an injured elbow joint can disturb the activity of daily life by limiting motion, especially if the motion is restricted over 40 degree of flexion contracture and under 105 degree of further flexion, it is imperative to select the best method and the timing of treatment of the elbow stiffness. Therefore this review will discuss open surgical techniques for stiff elbows based on the literature. Materials and Methods: It is important to take sufficient clinical examination of the patient, including history taking. And, a surgeon should select appropriate procedure after accurately understanding about the status and cause of the stiff elbow with radiographic methods. Surgical methods include arthroscopic release open release, distraction arthroplasty, total elbow replacement and there are four approachs in the open release - anterior approach, medial "over the top" approach, limited lateral approach: column procedure, posterior extensile approach-. Results and Conclusion: Although at present the arthroscopic technique is emphasized for the treatment of elbow stiffness, a surgeon should know conventional open techniques.

Background : The lung is the most common site for a metastasis of extrapulmonary malignant tumors. however, reports on an endobronchial metastasis are rare. An endobronchial metastasis is defined as a documented extrapulmonary neoplasms metastatic to the segmental or more proximal central bronchus within a bronchoscopically visible range. The purpose of this study was to define the clinical characteristics of an endobronchial metastasis of extrapulmonary malignancies. Materials and Methods : The clinical features and treatment outcomes of 27 endobronchial metastatic cancer cases were reviewed from June, 1991 to May, 2001 in the Severance Hospital. Results : The patients' age ranged from 18 to 75. There were 17 men and 10 women. The primary tumors included the colorectum in 7, the uterine cervix in 4, the stomach and the breast in 3 patients each, and an osteosarcoma in 2 patients. The main complaint of most patients was coughing and a chest X-ray revealed a hilar mass, a parenchymal, and an atelectasis. The mean recurrence interval time was 45.5 months. The median and mean survival times were 10 and 12.3 months, respectively. Conclusion : An endobronchial metastasis is an ominous finding, and is associated with advanced-stage diseases. It requires differential diagnosis with a primary bronchogenic carcinoma. If atypical clinical features are present or an atypical cell type is discovered by a biopsy of the lesion in the lung mass, the appropriate diagnostic studies should be undertaken.

Korean high speed train(HSR-350x) has adopted a combined electrical and mechanical(friction) braking system. Brake blending control unit(BBCU) controls each brake system to fulfill the required brake performances such as braking distance, deceleration and jerk. Also the braking system should be designed considering the economical management, such as effective use of generated braking energy and the minimum wear of friction materials(a pad and a brake shoe). In this paper, we establish the disc braking force pattern that reduces the wear of pad in the disc braking system by minimizing the variance of the instantaneous disk baking energy during braking time, and compare the wear mass of pad between the conventional disc braking force pattern and the established results.

Purpose: This study aimed to determine which factors are related to perforated appendicitis. We also conducted a survey to identify the causative organism. Methods: From January 2011 to December 2014, 569 pediatric patients (322 male) younger than 19 years old who underwent an appendectomy due to acute appendicitis at Hallym University Sacred Heart Hospital were enrolled. Patients' medical records were reviewed retrospectively to determine their clinical manifestations, laboratory and imaging results, and pathogens. Results: About 127 patients (22%) had perforated appendicitis. The rate of perforated appendicitis in preschool, late childhood, and adolescent ages were 50%, 27%, and 16.8%, respectively. The risk factors of perforation were high C-reactive protein levels and the presence of appendiceal fecalith (P<0.001). Of the 24 samples of peritoneal fluid and periappendiceal pus that were collected intraoperatively, 16 were culture positive. The most common pathogen was Escherichia coli (n=10), and others were Pseudomonas aeruginosa, Streptococcus spp., and Staphylococcus spp. Conclusions: The perforation rate of appendicitis among patients younger than 5 years old was 50%, and this decreased in proportion with age. Clinicians should be aware of the possibility of perforation when patients with appendicitis have high C-reactive protein levels or the presence of appendiceal fecalith on imaging.

Background : Many analgesics are used to relieve the pain of various causes. Among these, $Myprodol^{(R)}$, a combination analgesic with codeine, ibuprofen and paracetamol, was recently used as a new analgesics. This study was performed to survey the kinds of diseases, side effects and pain relief effect of $Myprodol^{(R)}$ in clincal practice. Methods : This retrograde study surveyed the medical records of 183 patients treated with $Myprodol^{(R)}$ at Pain Clinic, Pusan National University Hospital. From medical records, the disease entities, the pain characteristics, duration of $Myprodol^{(R)}$ medication, the analgesic effect and side effects were evaluated. Results : $Myprodol^{(R)}$ is used in the treatment of cancer pain (64.3%) and non-cancer pain (35.7%). Among side effects of $Myprodol^{(R)}$ medication, nausea with vomiting, constipation and generalized edema were common in cancer pain, but epigatric pain was common in non cancer pain. $Myprodol^{(R)}$ was more effective in non cancer pain than cancer pain. Conclusions: $Myprodol^{(R)}$ was used in cancer and non-cancer pain patients. In cancer pain patients, $Myprodol^{(R)}$ was effective in early cancer pain but, not effective in advanced cancer. $Myprodol^{(R)}$ was also used and effective in non-malignant benign chest pain, lumbago, post-operative pain.
