We report the case of a 32-year-old woman presenting with intermittent chest pain resulted from a migratory acupuncture needle. The patient received acupuncture treatment approximately 3 years prior to this presentation, for the treatment of chronic left shoulder and lumbar pain after delivery. Chest radiography revealed a retained needle in the lingular segmental area. Video-assisted thoracoscopy was then used to remove the migratory acupuncture needle attached between the lingular segmental lobe and the pericardial fat. The patient recovered without complications and was discharged home.

Idiopathic fibrosing mediastinitis is, an uncommon cause of pulmonary hypertension this is characterized by excessive fibrosis of the mediastinum with an unknown etiology. Steroid therapy has been suggested for individuals with progressive symptoms, bu there is littlet data demonstrating the efficacy of such therapy are lacking. We present a case of pulmonary hypertension secondary to a compression of a main pulmonary artery by fibrosing mediastinitis which was confirmed by a biopsy with a thoracotomy. The chest CT scan and 2D echocardiography performed before and after a trial of steroid therapy demonstrated improvement after steroid therapy.

Both bronchial leiomyoma and pulmonary sequestration are rare conditions, and to the best of our knowledge there are no reports of the two conditions coexisting. We report a female patient with bronchial leiomyoma with acquired pulmonary sequestration who presented with dyspnea, cough and purulent sputum. The patient had been treated for pneumonia at a local medical clinic. but was transferred to our clinic beacausr there was no clinical improvement. A 3-D computed tomography scan revealed a 1.5 cm sized mass near the distal portion of the left main bronchus and an anomalous artery arising from the aorta. The patient showed clinical improvement after a left lower lobectomy and a ligation of the anomalous artery.

BACKGROUNDS: This study investigated whether or not a polymorphism in the gene encoding the surfactant protein A(SP-A) has any bearing on the individual susceptibility to the development of chronic obstructive pulmonary disease(COPD) in a genetically homogenous Korean population. METHODS: The genotypes of 19 COPD patients and 20 healthy neonates as controls were tested using a polymerase chain reaction followed by restriction fragment length polymorphism analysis for the SP-A gene. RESULTS: The specific frequencies of the 6A2 and 6A18 alleles of SP-A1 and the 1A2 allele of SP-A2 were much higher in the COPD group than control group (p<0.05). However, the frequencies of the 6A3 and 6A4 alleles of SP-A1 and the 1A0 allele of SP-A2 in the COPD group were significantly lower than the control group. In the COPD group, the frequencies of the +50 locus genotypes GG of SP-A1 and the +9 locus genotypes CC of SP-A2 were 85.0% and 60.6%, respectively, and 19.7% and 24.8% in the control group, respectively. The frequencies of the polymorphic genotypes or alleles showed a statistically significant difference between the COPD group and the control group (P<0.05). CONCLUSION: A genetic polymorphism in SP-A is associated with the development of COPD in the Korean population.

BACKGROUND: Idiopathic pulmonary arterial hypertension (IPAH) and chronic thromboembolic pulmonary hypertension (CTEPH) are rare but significantly imperative in inducing chronic pulmonary hypertension. Clinically, it is difficult to distinguish between IPAH and CTEPH. However, the treatment of pulmonary hypertension is different depending on the disease. The present study was performed to analyze the similarities and differences in clinical features between IPAH and CTEPH. METHODS: During a nine-year period, thirty-three patients with IPAH and twenty-two patients with CTEPH were enrolled. Symptoms, physical findings, chest radiograph, electrocardiograph, pulmonary function test, echocardiograph, perfusion lung scan, right heart catheterization results were analyzed between both the groups. RESULTS: The median age of IPAH group was 33 (6~70) years that was lower than that (52(27~80) years) of CTEPH group. Amongst the IPAH patients, there was female predominance (76 %) and there was no sex difference between the patients with CTEPH. Both the groups exhibited similarity in the results of chest radiograph, electrocardiograph, pulmonary function test, and echocardiograph. In the perfusion lung scan, all IPAH patients exhibited findings with normal (28%) or low probability (72%) of pulmonary embolism and all CTEPH patients exhibited findings with high probability of pulmonary embolism. CONCLUSION: Although IPAH and CTEPH bear similarities in terms of symptoms, physical signs and general investigation results, there were differences in age distribution, sex predominance and results of perfusion lung scan.

Epithelioid hemangioendothelioma (EH) is a rare borderline malignant tumor which originating from vascular endothelial cells and occurs in many organs such as soft tissues, lung, liver and bone. But, pulmonary EH which simultaneously involves pleura and liver is very rare. In the present report, we describe an uncommon case of EH involving the lung, pleura and liver in a 26-year-old woman. Chest CT showed single nodule in right upper lobe with large amount of pleural effusion at ipsilateral side and abdominal CT multiple round low densities in liver. The EH was confirmed by microscopic analysis and immunohistochemical staining of CD34+ from open lung biopsy specimen.

An endobronchial leiomyoma is extremely rare benign tumor of the lung. Most endobronchial leiomyomas reported in the literature have been resected by either a lobectomy or a pneumonectomy. Herein is report a case whose tumor was successfully removed using a fiberoptic bronchoscope without surgical resection. A 64-year-old female presented with a fever, and a cough with purulent sputum of 10 days duration. The bronchoscopy revealed a 1cm sized, glistening, light yellow colored mass lesion totally obstructing the orifice of the superior segment of the right lower lobe. During the bronchoscopic biopsy procedures, the mass lesion was completely removed. A diagnosis of a leiomyoma was made from a histological examination of the obtained specimen. The early diagnosis and appropriate treatment including bronchoscopic removal may prevent respiratory complications.

Synovial sarcoma is a malignant soft tissue tumor originated from primitive mesenchymal cell and displays epithelial differentiation. Synovial sarcoma most commonly occurs in the peri-articular regions of the extremities in adolescents and young adults. But primary synovial sarcoma of the pleura is extremely rare. The present report describes a case of primary synovial sarcoma of the pleura in a 35-year-old male who showed unilateral spontaneous hemothorax as initial manifestation. The tumor mass was removed by open thoracotomy. The tumor was composed of oval to spindle cells with abundant vascular structures. Some of the spindle-shaped tumor cells express cytokeratin. A diagnosis of monophasic fibrous synovial sarcoma was made by histologic and immunologic features. The patient received chemotherapy postoperatively and showed no evidence of recurrence or tumor at other sites 1 year after surgery.

BACKGROUND: Bacterial infections in diabetic patients are an important cause of increased morbidity and mortality. It has been reported that bacterial infections in diabetics showed more impaired PMN functions such as reduced PMN respiratory burst and decreased microbicidal activity in inflammed tissues. Also, apoptosis(programmed cell death) is postulated to be a key mechanism for neutrophil elimination. It is very important that PMN apoptosis keeps the balance from an area of inflammation. Actuallly, as little was known about PMN apoptosis and respiratory burst in diabetes, we investigated PMN apoptosis and hydrogen peroxide production after endotoxin exposure. METHODS: Peripheral venous blood samples were collected by routine venipuncture from healthy volunteers and diabetics to harvest neutrophils. We respectively measured the PMN apoptosis, the production of hydrogen peroxide, and the cell viability. RESULTS: Normal neutrophils showed a tendency to decreased apoptosis after endotoxin treatment. In patients with diabetes, PMN apoptosis was significantly decreased compared with healthy controls. In addition, the LPS-induced neutrophils in diabetics demonstrated more decreased apoptosis. However, the production of hydrogen peroxide was not different between groups. CONCLUSION: These observations suggest that the decreased PMN apoptosis in diabetics with endotoxin exposure may also affect the increased susceptibility and severity of infections.

BACKGROUND: Diffuse alveolar hemorrhage (DAH) is an uncommon pulmonary disease. It could be occurred by diverse causes with the different response to the treatment. However, the clinical features of DAH have not been well known in Korea. METHODS: Twenty cases identified as DAH between March of 1990 and July of 2000 at a university affiliated hospital were retrospectively reviewed. RESULTS: The median age was 45 yr (range: 18~73 yr) with 11 females. Diagnosis was made by clinical and radiologic findings including hemoptysis, newly developed anemia, and diffuse bilateral lung opacities with the continuous bloody lavage fluid or bloody bronchial aspirate on bronchoscopy. The mean APACHE III score was 50.8 (+/-26.7) points. Hemoptysis prior to admission was observed in 8 (40%) patients. Diffuse crackles were heard on the bilateral lung fields in 18 cases. On chest radiographs, diffuse ground glass appearance and/or confluent air space consolidation with ill defined irregular margin were mainly observed. In patients with DAH the hemoglobin level fell a mean of 2.0 (+/-0.8) g/dL. Fourteen (70%) patients received mechanical ventilation due to the respiratory failure. Six patients (30%) were dead during admission. Among these patients, 4 patients were dead due to refractory respiratory failure with continuous DAH. The bleeding tendency such as disseminated intravascular coagulation or low platelet count was higher in dead patients than the survivors (p=0.018). The survivors of DAH with noninfectious causes showed better responses to immunosuppressive drugs with/without plasmapheresis compared to nonsurvivors (p=0.003). CONCLUSION: DAH was prone to develop acute respiratory failure and needed mechanical ventilation frequently. However, DAH of non-infectious causes showing a good response to the immunosuppresive therapy would have a better prognosis. In addition, DAH would have a worse prognosis in cases of combined bleeding tendency.
