Cardiac mesotheliomas are rare. It is difficult to diagnose them at an early stage because the symptoms are nonspecific. Here we report two cases that had been initially diagnosed as constrictive pericarditis but later were definitively diagnosed, after pericardiectomy, as mesothelioma. The two patients complained of dyspnea that lasted 4 months and 10 years. Chest CT showed mild pericardial effusion and thickened pericardium, which was found enveloping the heart without any lumps. Median sternotomy showed that the overall pericardium was thickened by more than 10 mm. Pericardiectomy (phrenic nerve to phrenic nerve) was performed and post-operative histology confirmed malignant mesothelioma. In one patient the disease recurred near the pericardium post-operatively at 7 months and the patient died at 11 months. The other patient received chemotherapy and was still alive at post-operative month 16. Pericardial mesothelioma is an extremely rare disease exhibiting clinical signs similar to those of constrictive pericarditis, and should be diagnosed at an early stage of onset.

The purpose of this study was to investigate the mediating effects of stress coping strategy on the relationship between academic burnout and school adjustment in Korea adolescents. A survey was conducted using a convenience sample drawn from 1,232 students from junior high schools in Kunggi Province. Data were analyzed using SPSS package program. The survey results showed that 44.6% of students are dissatisfied with their own academic grade. Antipathy and cynicism showed the most impact on academic burnout. In addition, academic burnout was negatively related with school adjustment. Especially academic burnout exerted inverse relationship with school adjustment, whereas problem oriented and seeking social support coping positively influence on school adjustment. Problem oriented and seeking social support coping partially mediated the relationship between academic burnout and school adjustment. The results indicate that improvement of active stress coping is important to prevent the symptoms of academic burnout and to increase the school adjustment.

Respiratory failure is the most serious manifestation and usual cause of death in acute organophosphate poisoning, and is common in acute cholinergic crisis. But the respiratory failure may appear suddenly in a patient who is recovering from the cholinergic crisis, even while receiving conventional therapy. These are case report of 37 years old male and 24 years old female with intermediate syndrome in organophosphate poisoning. The two patients ingested organophosphate(fenthion and mixture of DDVP with chlorpyrifos respectively) incidentally and in a sucide attempt respectively. After apparent recovery from the cholinergic crisis with a conventional therapy but before the expected onset of delayed polyneuropathy, the respiratory failure appeared suddenly with a muscular weakness, affecting predominantly the proximal limb muscles, neck flexors, territories of several motor cranial nerves. The two patients needed mechanical ventilatory support and recovery from the intermediate syndrome was complete in both patients, although one subsequently developed hypoxic encephalopathy. The clinical manifestation and electrophysiologic study support the clinical diagnosis of intermediate syndrome. The syndrome carries a risk of death. because of respiratory paralysis, if not recognized early and treated adequatedly. Prompt endotrachial intubation and mechanical ventilatory support is the cornerstone of treatment of the intermediate syndrome. Therefore, all patient should be observed in a hospital for up to 5 days after poisoning.

Hypereosinophilic syndrome (HES) is characterized by a sustained eosinophilia of $1,500/mm^3$ or more in the absence of any known causes or the signs and symptoms of organ involvement. We report a 64-year-old man with HES initially presenting with involvement of the liver and bone marrow. Despite controlling the eosinophilia by corticosteroid, he developed a cerebral infarction and later progressive interstitial pneumonia. Brain angiography revealed a severe stenosis of the proximal right internal carotid artery (ICA) and a complete obstruction of the intracranial ICA. An open lung biopsy revealed fibrosis and lymphoplasma cell infiltration without eosinophils, which were consistent with nonspecific interstitial pneumonia.

Background : The clinical results of a Natural stent in patients with a benign tracheobronchial stenosis were examined by comparing the clinical outcomes and complications of those patients who underwent Dumon and Natural stenting in the management of benign airway stenosis. Methods : The medical records of 94 patients (39 Dumon and 55 Natural stent) with a benign tracheobronchial stenosis were reviewed and analyzed. Results : Post-tuberculous stenosis was the leading indication for airway stenting (74%), which was followed by post-intubation stenosis (21%). After intervention, the dyspnea had improved among those patients who underwent Dumon (90%) and Natural (86%) stenting. After stabilizing the dyspnea, the stent could be successfully removed in half of the patients who underwent both Dumon (54%) and Natural (49%) stenting. During the 42 month follow-up period, the complication rate was similar in those patients who underwent Dumon and Natural stenting: migration (46% vs 53%), granulation tissue formation (36% vs 49%), mucostasis (21% vs 16%) and restenosis (51% vs 36%). Conclusion : The clinical results of Natural airway stent was similar to those of Dumon stent in the management of benign tracheobronchial stenosis.

A primary pulmonary artery sarcoma is a rare malignant tumor derived from the intimal layer of the pulmonary artery. Its clinical presentation can lead to a misdiagnosis of more common diseases such as thromboembolic disease. It is known to have a very poor prognosis. Therefore, the correct diagnosis of a primary pulmonary artery sarcoma is difficult and often delayed. We experienced a case of primary pulmonary artery sarcoma mimicking a pulmonary thromboembolism. The patient was admitted as a result of progressive dyspnea and coughing. The lung perfusion scan showed a large perfusion defect involving almost the entire right lung and suspicious small perfusion defects in the left upper lobe. Magnetic resonance imaging of the chest showed an enhancing nodule within the thrombus in the right pulmonary artery. The mass was removed completely by surgery, but the patient died as a result of shock.

This study was carried out to find out if peripheral neuropathy was resulting from exposed to pesticides in farmers. Thirty four male farmers in rural area of Chungju were selected as a study group. According to the farm type and area, the group was subdivided into two groups: the high exposed group(n=20) and the low exposed group(n=14). Nerve conduction velocity tests were done on four nerves of the dominant arm(median motor, median sensory, ulnar sensory, and ulnar motor) and three nerves of the dominant leg(peroneal motor, sural sensory, and posterior tibial motor). On the nerve conduction study, all of the results were included normal range. But comparing to reference mean values, most of results were significantly decreased(P < 0.01 by t-test). And the median motor conduction velocity and the peroneal nerve latency were significantly increased in the high exposed group than the low exposed group and reference values. But we concluded that these findings are caused by age difference not pesticide exposure. In conclusion, we cannot find any abnormality of nerve conduction velocity caused by exposure to pesticide in this study group.

Intestinal atresia is a frequent cause of intestinal obstruction in the newborn. We reviewed the clinical presentation, associated anomalies, types of atresias, operative managements, and early postoperative complications in 36 cases of intestinal atresia treated at the Department of Surgery, Kyungpook National University Hospital between January 1994 and February 2003. Location of the lesion was duodenum in 17 patients, jejunum in 11 patients and ileum in 8 patients. The male to female ratio was 1:1.4 in duodenal atresia (DA), 2.7:1 in jejunal atresia (JA) and 7:1 in ileal atresia (IA). The most common type was type III (41.1 %) in DA, and type I (52.6 %) in JA and IA. The most common presenting symptoms was vomiting(88.2 %) in DA, but in jejunoileal atresia, vomiting(89.4 %) and abdominal distension(89.4 %) were the most common sign and symptom. All cases of DA were diagnosed by plain abdominal radiography. There were 6 cases of DA with congenital heart disease, 3 cases of DA with Down syndrome and 3 cases of JA with meconium peritonitis. Segmental resection was performed in 13 cases, duodenoduodenostomy in 11 cases, membrane excision in 7 cases, jejunojejunostomy in 2 cases, gastroduodenostomy in 2 cases and ileocolic anastomosis in 1 case. There were 9 postoperative complications including 3 each of anastomotic leakage, wound infection, and intestinal obstruction 3 cases. The mortality rate for DA was 11.8 %(2/17). Both deaths in DA were attributed to congenital heart disease. The mortality rate for JA was 18% (2/11). Both cases died with sepsis and short bowel syndrome.

Coccidioidomycosis is a fungal infection acquired by inhalation of the arthrospore of Coccidioides immitis, and endemic disease in specific geographic areas, such as south central California, south Arizona. Nevada, and New Mexico. Approximately 60 percent of infected people is asymptomatic and the remainders mostly exhibit respiratory complaints, from flu-like coughing to overt pneumonia. Usually the infection due to Coccidioides immitis is self-limited. Symptoms resolve within several weeks but radiographic abnormalities could be resolved more slowly. If the radiographic abnormalities persist more than 8 weeks, the term' chronic pulmonary coccidioidomycosis' is designated. They take forms of nodules, cavities or progressive pneumonia. When manifested as nodule(s), lung malignancy is suspected as a possible diagnosis and histologic confirmation is needed. Here, we report a case of chronic pulmonary coccidioidomycosis manifested as solitary pulmonary nodule in a Korean woman who has traveled in Arizona, which is diagnosed finally by lobectomy and histologic examination.

Sternocostoclavicular hyperostosis is an uncommon disease, characterized by an inflammatory arthrosteitis of the sternocostoclavicular region. Clinically, it manifests as a painful swelling of the upper anterior chest wall, which is associated with occasional pustulosis palmaris and plantaris. A 48-year-old man had suffered from pain in both shoulders and the upper anterior part of the chest for 6 months. On examination, a venous engorgement in the neck with dilated collateral veins in the upper chest and shoulders was observed. Swelling was noticed in his face, neck and both arms. Radiologically, the clavicles, the sternum and the first ribs were enlarged with complete fusion between them. 99Tc scintigraphy showed increased uptake in the clavicles and the sternum. Selective venography resulted in a bilateral subclavian and brachiocephalic vein occlusion, which resulted from a subclavian vein thrombosis. All the above suggested a sternocostoclavicular hyperostosis. He underwent a vascular graft interposition between the right jugular vein and the left innomianate vein (using 8mm ringed Gore-Tex graft) and a resection of the bilateral medial half of clavicle and 1st rib. Here, we present a case on sternoclavicular hyperostosis with subclavian and brachiocephalic vein thrombosis, and report this case study with a review of the appropriate literature.
