Background: Cigarette smoking is well known to play an important role in the development of lung cancer. Inducible nitric oxide synthase (iNOS) can either promote or inhibit cell proliferation and growth, which makes its role in the development of malignant tumors controversial. The relation between cigarette smoking and iNOS in human lung cancer is unknown.

Spontaneous pneumothorax is one of the more common presentations of lymphangioleiomyomatosis; however, recurrences are common which can be challenging to manage particularly in bilateral pneumothorax. We present a case of recurrent bilateral spontaneous pneumothorax associated with lymphangioleiomyomatosis, diagnosed intra-operatively, and confirmed by the resected lung specimen. Video-assisted thoracic surgery bullectomy and mechanical as well as talc pleurodesis was required to prevent further recurrences.

Objective: Major surgery is immunosuppressive and could have an impact on postoperative tumor immunosurveillance and recurrence in cancer patients. Low circulating levels of insulin growth factor binding protein (IGFBP)-3 have been linked to advance prostate and the development of colonic cancers. This prospective study examined the early postoperative circulating levels of IGFBP-3, matrix metalloproteinase (MMP)-9, and tissue inhibitor of metalloproteinase (TIMP)-1 in early stage non-small cell lung cancer (NSCLC) patients undergoing major lung resection by VATS versus thoracotomy.

The development of video-assisted thoracic surgery (VATS) in the past decade has changed the way many pulmonary conditions are being treated. VATS has gained popularity among clinicians due to faster recovery following surgery, less postoperative pain and better cosmesis. It is well known that surgical trauma can induce a systemic inflammatory response and affect postoperative systemic immunity.

Bronchiolitis obliterans syndrome (BOS) is the main and late chronic complication after lung transplantation. It remains a major impediment to long-term outcome. Unfortunately, the survival rate of lung transplant recipients lags behind that of other organ transplant recipients, and BOS accounts for more than 30% of all mortality after the third year following lung transplantation.

The present report describes a case of severe airway obstruction caused by endobronchial tuberculosis in an 11-year-old girl who was successfully treated by bronchoscopic balloon dilation. This case illustrates the insidious presentation and the increasingly important role of bronchoscopic intervention in the management of endobronchial tuberculosis. In addition, a brief literature review of the condition in the pediatric age group is included.

Objective: The pain following thoracic surgery and trauma is often refractory to conventional analgesic strategies. However, it shares key characteristics with neuropathic pain which gabapentin, an anticonvulsant, has been proven to effectively treat. To our knowledge, this is the first prospective study assessing the use of gabapentin in cardiothoracic surgery patients.

Study Objectives: Minimal-access thymectomy has become increasingly popular as surgical treatment for patients with nonthymomatous myasthenia gravis (NTMG) because of its comparable efficacy, safety, and lesser degree of tissue trauma compared with conventional open surgery. We reviewed and analyzed our data on video-assisted thoracic surgery (VATS) thymectomy and present the clinical outcomes according to the Myasthenia Gravis Foundation of America classification.

Design: A retrospective review of VATS thymectomy for NTMG in a university hospital over a 12-year period.

Major surgery is immunosuppressive, and this could have an impact on postoperative tumor immunosurveillance and, therefore, long-term survival in cancer patients. Video-assisted thoracic surgery (VATS) lung resection is a new alternative surgical approach to thoracotomy for patients with early lung cancer. This is a pilot study to examine the postoperative changes in leukocytes, lymphocyte subsets, B cells, T cells, and natural killer (NK) cells in non-small-cell lung cancer (NSCLC) patients undergoing lung resection with VATS versus thoracotomy approaches.

Post-pneumonectomy empyema is an uncommon but potentially life-threatening complication. It has a strong association with bronchopleural fistula, which acts as a continued source of infection into the thoracic cavity. Numerous risk factors have been identified and strategies formulated to minimize its occurrence.

Alveolar capillary dysplasia with misalignment of pulmonary vessels is an uncommon congenital cause of persistent pulmonary hypertension of the newborn. It is universally fatal, and diagnosis is entirely dependent upon surgical lung biopsy. We present a case of alveolar capillary dysplasia with misalignment of pulmonary vessels occurring in a full-term neonate, emphasizing that early involvement of the thoracic surgeon for a histological diagnosis allows expensive and ineffective treatments to be avoided.

Objective: Chest wall paresthesia is a reported sequela of thoracotomy and Video-Assisted Thoracic Surgery (VATS) which is distinct from wound pain. Although needlescopic VATS confers less post-operative pain and better cosmesis, the incidence of paresthesia after needlescopic VATS has not been quantified.

Methods: For homogeneity of the patient cohort, we studied 50 patients who received bilateral needlescopic VATS sympathectomy (T2-T4 excision) for palmar hyperhidrosis using 2 or 3 mm instruments during a 36-month period at a single institute.

Adenocarcinoma (AdC) of the lung represents a common histologic subtype of non-small cell lung cancer. While there is a rising incidence of AdC in nonsmoking women, information on the cytogenetic changes involved has been minimal to date. In the present study, spectral karyotyping analysis uncovered the genome-wide chromosomal aberrations in two AdC tumors derived from women who were lifelong nonsmokers.

Objectives: Detection of cervical N3 lymph nodes is currently not a routine preoperative investigation for lung cancer patients. We designed a study to assess if the frequency and accuracy of detection of metastatic cervical lymph nodes using cervical ultrasonography (US) and fine needle aspiration (FNA) justify their routine use in all lung cancer patients with impalpable cervical lymph nodes.

Methods: Fifty patients with suspected and potentially operable non-small cell lung cancer were enrolled.
