[Surgical Treatment for Congenital Bronchial Atresia and Intralobar Sequestration in the Same Lobe].

A 21-year-old man who had a history of pneumonia twice presented with chest discomfort. Computed tomography( CT) revealed dilatation of the atretic bronchus that was not continuous with the proximal one, and surrounding hyper-lucent lung fields in the outer and mediastinal sides of the right basal segment, and the absence of B10b+c. CT also demonstrated the presence of A10b+c in the former field and the aberrant artery from the inferior phrenic artery in the latter.

A population-based study of outcomes in patients with surgically resected non-small cell lung cancer with anaplastic lymphoma kinase-rearranged mutations: A matched-pair study.

The present study aimed to evaluate clinical outcomes in patients with surgically resected non-small cell lung cancer (NSCLC) with anaplastic lymphoma kinase (ALK)-rearranged mutations.

This study aimed to characterize tongue and pharyngeal pressure in myotonic dystrophy type 1 (DM1), Duchenne muscular dystrophy (DMD), and amyotrophic lateral sclerosis (ALS) patients.

Methods: This study recruited 17 DMD patients, 32 DM1 patients, and 26 ALS patients.

Three-dimensional computed tomographic volumetry precisely predicts the postoperative pulmonary function.

Purpose: It is important to accurately predict the patient's postoperative pulmonary function. The aim of this study was to compare the accuracy of predictions of the postoperative residual pulmonary function obtained with three-dimensional computed tomographic (3D-CT) volumetry with that of predictions obtained with the conventional segment-counting method.

Methods: Fifty-three patients scheduled to undergo lung cancer resection, pulmonary function tests, and computed tomography were enrolled in this study.

Thick lung wedge resection for acute life-threatening massive hemoptysis due to aortobronchial fistula.

Massive hemoptysis from an aortobronchial fistula due to thoracic aortic dissection is an extremely rare symptom, but is a potentially life-threatening condition. We report a case of acute massive hemoptysis due to aortobronchial fistula that was successfully controlled by a simple and rapid thick wedge resection of the lung with hematoma by using the black cartilage stapler. A 65-year-old man was admitted to our hospital with acute massive hemoptysis.

Improved Lung Cancer Detection in Cardiovascular Outpatients by the Pulmonologist-based Interpretation of Chest Radiographs.

Objective: Pulmonologists and cardiologists view chest radiographs differently. Lung cancer may therefore go undetected in patients referred to cardiovascular departments. We aimed to determine the clinical benefit of the additional interpretation of chest radiographs by pulmonologists in study involving cardiovascular outpatients.

Subscapularis muscle flap for reconstruction of posterior chest wall skeletal defect.

Introduction: Chest wall skeletal defects are usually closed using muscle flaps or prosthetic materials. Postoperative prosthetic infections are critical complications and often require plastic surgery support. We report a new surgical technique, involving a subscapular muscle flap, for covering posterior chest wall defect.

Video-assisted thoracoscopic conservative repair of postoperative lobar torsion.

Postoperative lobar torsion is a rare and life-threatening complication. Several previous cases have been treated with completion lobectomy. We report successful surgical repair of middle lobar torsion after upper lobectomy.

Erlotinib for elderly patients with non-small-cell lung cancer: Subset analysis from a population-based observational study by the Ibaraki Thoracic Integrative (POSITIVE) Research Group.

The incidence and mortality of lung cancer have increased worldwide over the last decades, with an observed increased incidence particularly among elderly populations. It has not yet been determined whether erlotinib therapy exhibits the same efficacy and safety in elderly and younger patients with non-small-cell lung cancer (NSCLC). The aim of this retrospective subgroup analysis of data from a population-based observational study was to assess the efficacy and safety of erlotinib in an elderly (≥75 years, n=74) and a younger group of patients (<75 years, n=233) who received treatment for NSCLC.

The influence of serum sodium concentration on prognosis in resected non-small cell lung cancer.

Background: Hyponatremia is the most common electrolyte disorder and is a negative prognostic factor in several kinds of cancer. However, few reports have referred to hyponatremia in non-small cell lung cancer (NSCLC). In the present study, the authors examined the influence of preoperative serum sodium concentration on survival in completely resected NSCLC.

Early-stage thymic carcinoma: is adjuvant therapy required?

Although the prognosis of advanced thymic carconoma remains poor, previous reports have shown survival rates of 70% to 100% in patients with Masaoka stage I or stage II of the disease who were treated with surgery followed by adjuvant therapy. However, the role of adjuvant therapy in these stages is controversial. We retrospectively evaluated the outcome of 4 patients with Masaoka stage II thymic carcinoma who were treated with surgery alone between 1992 and 2008.

There is no standard treatment and there are no clearly defined guidelines for the treatment of postoperative recurrent non-small-cell lung cancer (NSCLC). We performed a retrospective population-based study to assess the benefits of treatment with gefitinib in patients with a postoperative recurrence of NSCLC in general clinical practice. This retrospective population-based study was conducted on patients with postoperative recurrent NSCLC who had been treated with gefitinib at 14 institutions in Ibaraki Prefecture between July 2002 and September 2007.

Significant correlation between endothelial nitric oxide synthase (eNOS) expression and alveolar repair in elastase-induced rat pulmonary emphysema.

Background And Purpose: Angiogenic factors, such as endothelial nitric oxide synthase (eNOS), are thought to play an important role in the repair of pulmonary emphysema (PE); yet, the correlation of the factors involved has not been investigated. We conducted this study to clarify the positive correlation between eNOS expression and alveolar repair in PE recovery.

Methods: We used elastase to induce PE in rats, which were divided into Groups A (Control), B (G-CSF), C (PE) and D (PE + G-CSF).
