Background: Hypersensitivity pneumonitis (HP) is an increasingly recognized form of diffuse parenchymal lung disease. Krebs von den Lungen-6 (KL-6) is now classified as a human MUC1 mucin protein, and regenerating type II pneumocytes are the primary cellular source of KL-6/MUC1 in the affected lungs of patients with interstitial lung diseases (ILD). Serum KL-6/MUC1 levels have been demonstrated to be useful for the evaluation of various ILD. To determine the role of circulating KL-6 in evaluating the disease activity and management of HP. Methods: An observational cross-sectional study was conducted on 51 patients with HP and 20 healthy controls. Serum KL-6 levels were measured in both groups. Patients were further assessed based on chest high-resolution computed tomography (HRCT), pulmonary function test, 6-minute walk test, echocardiography, bronchioalveolar lavage, and/or transbronchial biopsy. Patients were divided into the fibrotic and non-fibrotic groups according to the HRCT findings. Results: The median serum KL-6 levels were significantly higher in HP patients as compared to the control group. The median serum KL-6 levels were found to be higher in the non-fibrotic HP group (1,900 IU/mL) as compared to the fibrotic group (1,200 IU/mL). There was a significant inverse correlation between serum KL-6 serum level and the dose of steroids as well as the duration of steroid therapy. Conclusion: The presence of higher KL-6 levels in the non-fibrotic HP group implies its enhanced production by regenerating pneumocytes in response to alveolar injury. The significant association between serum KL-6 levels and the dose and the duration of steroid therapy emphasizes the significant role of steroids in the stabilization of the disease.

We experienced a rare case of a recanalization and aneurysmal formation of the previously ligated PDA on 18 year-old-girl. Continuous murmur was noted 3 months after operation and this recanalization was confirmed by angiography and cardiac catheterization. It was impossible to mobilize aneurysmal PDA with safety, so we closed the defect using left heart bypass to prevent spinal card injury. Postoperative course was uneventful and the patient was discharged in good condition.

The strictured esophagus is not removed usually in corrosive injury. But corrosion carcinoma and the late complications such as esophago-bronchial fistula, chronic mediastinal abscess, diverticulum can occur in case that strictured & inflamed esophagus be remained. Recently transhiatal esophagectomy is being done with low mortality and morbidity. So we are reporting 2 cases of esophageal stricture in young patients which were treated with transhiatal esophagectomy and esophagocologastrostomy. All of 2 cases were successfully treated and recovered. Postoperative esophageal function tests showed the mild reflux but it did not count clinically.

We report a case of delayed diagnosed pneumonia due to an aspirated metallic crown, which had been detached from a molar tooth. Dental prosthesis should be checked and a careful review of the chest radiograph is mandatory when an elderly patient with delirium after hip fracture surgery develops pneumonia postoperatively.

The tracheobronchial rupture from blunt trauma is an uncommon injury with a variety of clinical presentations. Most of traumatic tracheobronchial tears occur within 2.5cm of the tracheal carina; lobar or segmental bronchi are rarely affected. Recently we experienced one case of traumatic rupture of right middle lobar bronchus in a patient who had fallen from a bicycle. Bronchoscopy showed linear disruption of the right middle lobe bronchus at its bifurcation site. Emergency right middle lobectomy was performed. The patient was recovered without any sequelae.

Still a lethal injury, traumatic rupture of thoracic aorta occurs more frequently than we expect and comprises significant part of causes of deaths by blunt trauma. We recently experienced a thoracic aortic rupture accompanied by multiple injuries including pericardial and interatrial septal rupture and myocardial contusion in a patient who had been injured in a fall accident. Literatures are reviewed with the concern of early diagnosis, surgical technique and the result of operation.

We present a case of ruptured abdominal aortic aneurysm caused by blunt injury. The patient was 23-year-old soldier injured by a motor vehicle accident. Injuries sustained a contused abdominal aorta. At the time of aortic repair, the involved segment formed huge pseudoaneurysm, and which had intimal tear. Aorto-iliac graft replacement was carried out with a woven-dacron Y-graft prosthesis, which restored satisfactory circulation to both lower limbs. The postoperative course was uneventful.

Blunt cardiac trauma is typified by the injury caused by the steering wheel in automobile collision. We experienced a case of IVC rupture due to in-car TA. The operation was performed under deep hypothermia with circulatory arrest to close the ruptured site by continuous over and over suture method with 3-0 prolene.

A 45-year-old woman was diagnosed as having chylothorax after a mitral valve replacement for mitral stenosis. direct injury of lymphatics in thymus a ramification of thoracic duct was presumed to be responsibe for this complication. Four weeks of conservative treatment failed and surgical treatment was performed, We report a case of surgical treatment for chlyothorax after and open heart surgery.

Lung transplantation is a life-saving procedure in patients with end-stage lung disease. However, it inherently depends on the availability of donor organs. The selection of suitable lungs for transplantation, management of donors to minimize further injury and improve organ function, and safe procurement remain critical for successful transplantation. In this review, we provide an update on the current understanding of donor selection, management, and lung procurement.
