BACKGROUND: Since 1992, we developed the technique for video endoscopic sympathectomy to treat palmar hyperhidrosis. It was soon proven to be a simple and effective therapy for essential hyperhidrosis. Compensatory hyperhidrosis, however, is the main cause of patient dissatisfaction after video-assisted thoracoscopic sympathectomy. According to many authors, initial satisfaction rate was high(94-98%), but it was declined with time (66%) due to mainly to embarrassing side effects. MATERIAL AND METHOD: From January 1992 to February 1998, the thoracoscopic T2 sympathicotomy, T2 sympathectomy and T2-4 sympathectomy were performed in 315 patients suffering from Essential hyperhidrosis in the Department of Thoracic and Cardiovascular Surgery in the Respiratory Center of Yongdong Severance Hospital Seoul, Korea. Eighty-nine patients underwent T2 sympathicotomy, and Eighty-eight patients underwent division T2 sympathectomy. RESULT: All of the treated patients obtained satisfactory alleviation of essential hyperhidrosis. The global rate of compensatory sweating were ; 64.0% in T2 sympathicotomy, 73.8% in T2 sympathectomy and 87.8% in T2-4 sympathectomy. The rate of embarrassing or disabling compensatory sweating was significantly higher in T2 sympathicotomy 15.7%(14/89) and in T2 sympathectomy 32.8%(28/88) than in T2-4 sympathectomy 58.0%(80/138) with significancy in statistic analysis(p<0.05). Video- assisted thoracoscopic sympathectomy is an effective minimally invasive and effective procedure. CONCLUSION: We suggest that the incidence and degree of compensatory hyperhidrosis was closely related to the extent of thoracic sympathectomy.

We report on a 41-year-old woman with a chest wall desmoid tumour who was successfully treated with a computed tomography (CT)-guided steroid injection. She presented with a palpable mass in the right upper chest wall and was treated by surgical excision and postoperative radiation therapy due to recurrence of the mass at the surgical site. At 20 months after the second operation, a recurrent mass was again detected in the anterosuperior portion of the previous surgical site on CT. We performed a CT-guided steroid injection weekly for 4 weeks by applying a mixture of 3 mL of triamcinolone acetonide (40 mg/mL) and 3 mL of 1% Lidocaine, administering 4-6 mL of the mixture, to the lesion. Six months later, CT showed a marked decrease in the size of the mass.

Lung transplantation has been successfully employed for variety of obstructive lung disease. Single lung transplantation has become a therapeutic option for end-stage obstructive lung disease. The patient, a 57 year old man with emphysema, suffered from severe dyspnea, which progressively aggravated him for the last three years. A single lung transplantation was performed from a young brain-dead donor on April 7th, 1999 in the department of thoracic surgery, Respiratory Center, Yongdong Severance hospital, yonsei University. The immunosuppressive regimen was based on cyclosporine A and azathioprine from beginning, adding steroid. Single lung transplantation was feasible and beneficial in patients with end-stage emphysema.

The transient receptor potential vanilloid 4 (TRPV4) cation channel, a member of the TRP vanilloid subfamily, is expressed in a broad range of tissues where it participates in the generation of Ca2+ signals and/or depolarization of the membrane potential. Regulation of TRPV4 abundance at the cell surface is critical for osmo- and mechanotransduction. Defects in TRPV4 are the cause of several human diseases, including brachyolmia type 3 (MIM:113500) (also known as brachyrachia or spondylometaphyseal dysplasia Kozlowski type [MIM:118452]), and metatropic dysplasia (MIM:156530) (also called metatropic dwarfism or parastremmatic dwarfism [MIM:168400]). These bone dysplasia mutants are characterized by severe dwarfism, kyphoscoliosis, distortion and bowing of the extremities, and contractures of the large joints. These diseases are characterized by a combination of decreased bone density, bowing of the long bones, platyspondyly, and striking irregularities of endochondral ossification with areas of calcific stippling and streaking in radiolucent epiphyses, metaphyses, and apophyses. In this review, we discuss the potential effect of the mutation on the regulation of TRPV4 functions, which are related to human diseases through deviated function. In particular, we emphasize how the constitutive active TRPV4 mutant affects endochondral ossification with a reduced number of hypertrophic chondrocytes and the presence of cartilage islands within the zone of primary mineralization. In addition, we summarize current knowledge about the role of TRPV4 in the pathogenesis of several diseases.

BACKGROUND: Hyperhidrosis of the palms, axillae and face has a strong negative impact on social and professional life. The present existing non-operative therapeutic options seldom give sufficient relief and have a transient effect. A definitive cure can be obtained by upper thoracic sympathectomy. However, this is offset by the occurrence of a high rate of side effects, such as embarrassing compensatory sweating. MATERIAL AND METHOD: From Sep. 1997 to Feb. 1998, 89 cases of the needle(2 mm) thoracoscopic thoracic sympathicotomy were performed. The second thoracic ganglion was resected by cutting with a endoscissors. RESULT: A bilateral procedure takes less than 25 min and requires just one night in hospital. There have been no mortality or life-threatening complications. One patient(<2%) required intercostal drainage because of pneumothorax. Primary failure occurred in one cases(<2%) and recurrent hyperhidrosis occurred in no cases. The patients with failure was successfully re-sympathicotomy. At the end of postoperative follow-up(median 3 months), 96.6% of the patients were satisfied. Compensatory sweating occurred in 57 cases(64.0%) with fourteen of those cases classified as either embarrassing in 10 cases(11.2%) or disabling in 4 cases(4.5%). CONCLUSION: Endoscopic transthoracic sympathicotomy is an efficient, safe and minimally invasive surgical method for the treatment of palmar and craniofacial hyperhidrosis.

Lung transplantation in the treatment of end-stage emphysema has been increasing in number since the recent rise in the 5 year survival rate. For the shortage of donor lungs, the single lung transplantation or transplantation in ABO compatible, nonidentical recipients has also been increasing. The lung transplantation in compatible, nonidentical recipients show good results as with identical recipients with the proper application of immunosuppressive agents. We transplanted the left lung of a 41 year-old male donor to a 35 year-old female recipient who had been suffering from severe dyspnea due to end-stage emphysema. For postoperative immunosuppression, we applied conventional triple immunotherapy(cyclosporine, azathioprine, prednisolone) and we could suppress the rejection response of transplanted lung by adding the anti-CD3 antibody(OKT3) during the operation. The patient could be discharged without any specific problem at 18th postoperative day.

Benign Tracheobroncheal tumor is a rare disease such as 1.9% of all tumor of pulmonary origin. Because clinical manifestation of benign tracheal tumor resembles that of broncheal asthma, these patients are usually treated in a way that used in broncheal asthma. Therefore, the diagnosis is delayed. We experienced a case of tracheal neurilemmoma that awed by bronchoscopic laser therapy. A 23-year-old woman visited ow hospital be cause of progressing dyspnea especially during inspiration. She was treated with aminophylline and 2 agonist under the impression of bronchial asthma at a local clinic. But because the symptoms were not relieved and pulmonary function test revealed variable extrathoracic lesion, we conducted bronclxaopy and biopsy. There were 1.5 x 2cm sized movable mass with stalk attached right anterior wall of bronchus. The biopsy result was neurilemmoma. Therefore we conducted bronchoscopic Laser therapy four times and the lesion disappeared in bronchosccpy and chest CT.

A 24-year-old man that had previously undergone a complete resection of a cervical paraganglioma presented with multiple well-defined intrapulmonary nodules on contrast-enhanced computed tomography. All of the nodules showed homogeneously intense enhancement. The largest nodule was a hot spot on F-18 fluorodeoxyglucose positron emission tomography. It was diagnosed as a paraganglioma using wedge resection via video-assisted thoracoscopic resection. Paragangliomas are rare neuroendocrine tumors and are exceedingly rare in the lung parenchyma. A few reports have described one or two intrapulmonary lesions, including primary tumors and metastases. We report a unique case of a multiple metastatic paraganglioma in the parenchyma of both lungs.

Pancreatic metastasis from papillary thyroid cancer (PTC) is extremely rare; only 18 cases have been reported in the literature. However, several reviews have highlighted similar characteristics between metastatic and primary pancreatic tumors. The patient was a 51-year-old male with a history of total thyroidectomy, modified radical neck dissection, and radioactive iodine ablation for PTC in 2014. Nodules suspected of metastasis were found in both lungs on chest computed tomography (CT). However, after 6 months, a follow-up chest CT showed no increase in size; thus, a follow-up observation was planned. Six years after his initial diagnosis, abdominal CT and pancreas magnetic resonance imaging revealed a 4.7 cm cystic mass with a 2.5 cm enhancing mural nodule in the pancreas tail. We diagnosed the pancreatic lesion as either metastatic cancer or primary pancreas cancer. The patient underwent distal pancreato-splenectomy. After surgery, the pathological report revealed that the mass was metastatic PTC. Pancreatic metastasis from PTC indicates an advanced tumor stage and poor prognosis. However, pancreatectomy can increase the survival rate when the lesion is completely resectable. Therefore, surgical resection should be considered as a treatment for pancreatic metastasis from PTC.

BACKGROUND: The incidence of chronic obstructive pulmonary disease (COPD) is increasing and the disease is becoming an important cause of morbidity and mortality worldwide. It is important to implement evidence-based guidelines by primary care physicians (PCPs) to establish qualified management of COPD patients. The aim of this survey is to investigate the pattern of COPD management among PCPs and to apply it to the development of Korean COPD guidelines. METHODS: A web-based questionnaire was prepared that consisted of 25 questions on the pattern of COPD management. A total of 217 PCPs participated in the survey from June 2006 to May 2007. RESULTS: Many PCPs (61.8%) possessed a spirometer, but the application rate was relatively low (35.8%) and more than half of the COPD patients (57%) did not receive a diagnosis based on spirometry. Administration of oral medication was preferred than the administration of inhaled medication for both stable COPD and acutely exacerbated COPD. More than 90% of the PCPs endorsed educational measures to quit smoking and vaccinate against influenza. It was noted that 56.7% of the PCPs were aware of the GOLD guidelines, but only 7.3% tended to fully implement the recommendations of the guidelines in daily practice. CONCLUSION: The results of the survey indicate that despite the high awareness rate of the current COPD guidelines, deficits exist among the PCPs with respect to the diagnosis and treatment of COPD. The results of this survey should be applied for the development of new COPD guidelines in order to decrease the discrepancy between the guidelines and the daily practice of the PCPs.
