An Elderly Smoker Presenting With Pulmonary Langerhans Cell Histiocytosis: An Unusual Demographic.

Cureus 2021 May 8;13(5):e14901. Epub 2021 May 8.

Pulmonary and Critical Care Medicine, McLaren Health Care, Flint, USA.

Pulmonary Langerhans cell histiocytosis (PLCH) is a rare neoplastic condition that occurs almost exclusively in young smokers and presents with multiple solid and/or cystic nodules in a primarily upper lobe distribution on chest imaging. Frequently, suspicion arises incidentally on imaging performed for alternative reasons, such as lung cancer screening, but diagnosis requires biopsy studies. We describe an uncommon case of PLCH in an elderly female patient presenting with mild dyspnea and a significant history of smoking. Read More

Selective Lobe Ventilation and a Novel Platform for Pulmonary Drug Delivery.

J Cardiothorac Vasc Anesth 2021 May 4. Epub 2021 May 4.

Department of Cardiothoracic Surgery, Wake Forest Baptist Medical Center, Wake Forest University, Winston-Salem, NC.

The current methods of mechanical ventilation and pulmonary drug delivery do not account for the heterogeneity of acute respiratory distress syndrome or its dependence on gravity. The severe lung disease caused by severe acute respiratory distress syndrome coronavirus 2, coronavirus disease 2019, is one of the many causes of acute respiratory distress syndrome. Severe acute respiratory distress syndrome coronavirus 2 has caused more than three million deaths worldwide and has challenged all therapeutic options for mechanical ventilation. Read More

Salvage surgery after definitive chemoradiotherapy through VATS for an initial unresectable locally advanced lung cancer: an alternative consolidative modality to radiotherapy?

Surg Case Rep 2021 Jun 8;7(1):138. Epub 2021 Jun 8.

Division of Thoracic Oncology, Department of Chest Medicine, Taipei Veterans General Hospital, Taipei, Taiwan.

Background: Definitive chemoradiotherapy (dCRT) is the first choice treatment for patients with locally advanced non-small cell lung cancer (NSCLC), but up to 35% of dCRT-treated tumors may have persistent or recurrent disease. Since the last decades, multimodality therapy showing potential for cure has become the mainstream for treatment of locally advanced NSCLCs, even some that were initially inoperable. Although salvage lung resection after dCRT has been reported with acceptable survivals, experiences in this respect are still limited. Read More

The Evolving Concept of Complete Resection in Lung Cancer Surgery.

Cancers (Basel) 2021 May 25;13(11). Epub 2021 May 25.

Department of Thoracic Surgery, Hospital Universitari Mútua Terrassa, University of Barcelona, Plaza Dr. Robert 5, 08221 Terrassa, Spain.

Different definitions of complete resection were formulated to complement the residual tumor (R) descriptor proposed by the American Joint Committee on Cancer in 1977. The definitions went beyond resection margins to include the status of the visceral pleura, the most distant nodes and the nodal capsule and the performance of a complete mediastinal lymphadenectomy. In 2005, the International Association for the Study of Lung Cancer (IASLC) proposed definitions for complete, incomplete and uncertain resections for international implementation. Read More
