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.

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.

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.

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.

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.

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.

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: The heat shock protein (HSP) 70 families are known to protect cells against the irreversible tissue injury induced by stress and to induce the recovery of cell function during stress. Heat pretreatment was reported to decrease the acute lung injury(ALI) of rats induced by lipopolysaccharide (LPS). However the role of heat shock with LPS co-treatmenton ALI is unclear. The purpose of this study was to investigate the effect of heat treatment, which was given immediately after the beginning of ALI induced by LPS intratracheally administered in rats. METHODS: Either saline (saline group) or LPS was intratracheally instilled without heat treatment (LPS group). In addition, heat was conducted 18 hours prior to the instillation of LPS (pre-treatment group) and conducted immediately after instillation of LPS (co-treatment group). Six hours after the LPS or saline treatment, blood, bronchoalveolar lavage (BAL) fluid and lung tissue samples were obtained. The myeloperoxidase (MPO) activity and the heat shock protein expression in the lung tissue, the differential counts of the polymorphonuclear leukocytes (PMN) in the BAL fluids, and the LDH, protein, IL-1beta, TNF-alpha and IL-10 levels in BAL fluid and serum were measured. RESULTS: 1)The MPO activity, the differential PMN counts in the BAL fluid, BAL fluid and serum cytokines were higher in the LPS, the heat pre-treatment and co-treatment group than those of the saline group (p value <0.05). 2)The MPO activity and the protein level in the BAL fluid from the heat co-treatment group were similar to those of the LPS group. 3) The serum TNF-alpha level of the heat co-treatment group was significantly higher than that of the LPS group (p=0.01) . CONCLUSIONS: Heat shock response administered immediately after a LPS instillation did not attenuate the ALI in this model.
