Acute interstitial pneumonia is a fulminant disease of unknown etiology that usually occurs in a previously healthy person and produces the histologic findings of the organizing phase of diffuse alveolar damage. We experienced an autopsy case of acute interstitial pneumonia of unknown etiology. The patient was a 48 year old man who had been healthy and had not been exposed to organic dusts or other toxic materials. The chief complaints represented were dyspnea and a dry cough for several weeks before hospitalization, and the chest radiographs showed bilateral interstitial infiltrates. Patchy consolidation of air space was also identified and ground-glass attenuation similar to those described in ARDS was detected on high-resolution computed tomography. Steroid pulse therapy, mechanical ventilation, and antibiotics for superimposed bacterial infection were performed, but the symptoms did not improve and the patient died of generalized respiratory insufficiency and severe hypoxemia 2 1/2 months after hospitalization. At autopsy the macroscopic and microscopic findings were confined mainly to the lungs. On the whole, both lungs were firm in consistency and the external surface showed a cobblestone appearance. The cut surface showed almost complete replacement of the normal lung parenchyma with gray to yellow fibrous tissue with a little residual functional area remaining. The pathology of both open lung biopsy and autopsy tissue showed marked hyperplasia of type II pneumocytes, hyaline membrane formation, thickening of the alveolar wall due to extensive fibroblast proliferation, and relatively abundant young collagen deposition in the interstitium. An immunohistochemical stain for cytokeratin revealed epithelial hyperplasia and showed that the alveolar spaces were markedly shrunken by fibrous tissue.

PURPOSE: Helicobacter pylori infection is probably acquired in childhood and persists as an asymptomatic infection for decades in most individuals. It is unclear why only a minority of those infected develop a clinical manifestation, even in childhood, such as peptic ulcer disease. H. pylori infection activates local immune responses and causes lymphocyte infiltration in the gastric mucosa. We have previously reported that both T and B cells in the lamina propria play important roles in the local immune response of H. pylori-infected children. The aim of this study was to investigate the association between H. pylori genotypes and gastric mucosal lymphocytes. METHODS: Twenty-five H. pylori-infected children (10 with peptic ulcer disease and 15 with gastritis) were enrolled in this study. We investigated the genotypes (cagA, cagE, vacA, and babA2) and evaluated the association with clinical manifestations, histopathology, and gastric mucosal lymphocytes. RESULTS: The prevalence of cagA, cagE, vacA s1m1, and babA2 was 80%, 60%, 84%, and 88%, respectively. The most prevalent (68%) combination of cagA, vacA, and babA2 genotypes was cagA+/ vacA s1m1+/babA2+. H. pylori genotypes were not associated with clinical manifestations, histopathology, or gastric mucosal lymphocytes. CONCLUSION: There was no association between the cagA, cagE, vacA, or babA2 status and gastric mucosal lymphocytes. The role of the host immune response in relation to H. pylori genotypes and disease potential in children needs further studies.

OBJECTIVES: Massive pulmonary hemorrhage (MPH) is a lethal disease, that large amount of blood is spouted from lung with clinical exacerbation, leading to death in newborn infants. Many of its causes were proved but debated. The purpose of this study is to determine the risk factors of Massive pulmonary hemorrhage of the newborn infants. We defined Mild pulmonary hemorrhage (mPH) as small amount of bleeding from lung with no changes in patient's clinical status. METHODS: Risk factors of MPH were estimated by retrospective multivariable analysis among newborn infants with pulmonary hemorrhage in neonatal intensive care unit of Catholic University Hospital of Daegu from January 2001 to December 2007. RESULTS: Pulmonary hemorrhage was developed in 73 neonates (6.3% of total infants admitted to NICU during the study period) and MPH occurred in 25 neonates (34.2%). Gestational age and Birth weights were lower in neonate with MPH than those with mPH. Thrombocytopenia and hypotension were statistically higher in those with MPH than mPH. There were no different significances between MPH and mPH in mean Bomsel grades of respiratory distress syndrome (RDS), Asphyxia, sepsis, disseminated intravascular coagulopathy (DIC), persistent ductus arteriosus (PDA), and intraventricular hemorrhage (IVH). CONCLUSION: The risk factors for massive pulmonary hemorrhage in newborn infants might be thrombocytopenia, and hypotension.

PURPOSE: The purpose of this study is to evaluate the knowledge and attitudes of oncology ward nurses toward cancer pain management and to find ways to improve the educational program for nurses. METHOD: A total of 209 nurses working at the oncology ward of three hospitals in Seoul and a Gyenggi Province. The survey instrument used was the 32-item scale for evaluating nurses knowledge and attitudes originally developed by McCaffery and Ferrell'(1990), that was by Kim'(1997). RESULTS: In terms of the nurses knowledge of pain management, the result showed that the nurses scored an average of 67.8 out of 100 for phamacokinetics of opioids, 84.8 for classification of analgesics, 60.1 for pain assessment, and 70.7 for drug administration. 18.2% of the nurses hesitate to inject the narcotic agent because of concerns regarding the drug's potential side effects. there was significant difference in the knowledge of pain management according to the general characteristics of pain in terms of the nurses age(p=.001), position (p=.016), years of experiences(p=.002), experience of cancer pain education(p=.001). CONCLUSION: The also showed that nurses working at cancer ward lack knowledge. It is important to provide intensive education to nurses about cancer pain management.

Colorectal carcinomas occur primarily in elderly people and are rare in children. Unlike adult colorectal carcinomas, the overall prognosis is very poor because of the usual delay in diagnosis and advanced stages at presentation or initial diagnosis, and a high incidence of aggressive tumor pathology such as mucinous adenocarcinoma. Colon cancer should not be excluded in children only based on age or barium enema results. Therefore, colonoscopy should be performed in pediatric patients with unexplained rectal bleeding and abdominal pain. We report a rare case of a child with a mucinous adenocarcinoma of the sigmoid colon in a 12-year-old boy, who presented with an abdominal mass and abdominal pain and review the medical literature.

Thoracic outlet syndrome is a relatively common disease. However, costoclavicular syndrome as a condition secondary to nonunion of a displaced fracture of the clavicle is very rare. Most clavicular fractures in adults are united with no or minimal persistent symptoms. Also, symptomatic nonunion of a displaced fracture of the clavicle is rare. A 55-year-old male initially presented with persistent forearm pain after slip-down was initially diagnosed with simple muscle strain. However, he was given a delayed diagnosis of costoclavicular syndrome, caused by compression of the subclavian artery due to trauma in the fibrotic nonunion of the right clavicle without apparent symptoms. We obtained satisfactory results by surgical treatment. Here we report this case with a review of the literature.

Dermatofibrosarcoma protuberans(DFSP) is a rare cutaneous tumor, which occurs most commonly on the trunk or the proximal extremities, affects all races and often develops between the second and fifth decades of life. It is uncommon in childhood and is sometimes mistaken for a vascular lesion, as it often presents as a blue macule or small nodule. Histologically, it shows large uniformed spindle shaped cells arranged in a cartwheel or storiform pattern. Recently, the immunohistochemical staining with monoclonal antibody to CD34 is reported to give assistance in the differential diagnosis of DFSP from the fibrous or neural tumors. We report herein a case of childhood DFSP showing CD34 positivity in a 9-year-old girl
