Despite recent advances in targeted therapy of non-small cell lung cancer (NSCLC), many patients do not benefit from these therapies. Inhibition of PD1/PDL1 is an interesting therapeutic target which restores the immune system against tumor cells. PD1 is located on lymphocytes and PDL1 on the antigen presenting cells. ⋯ Anti-PD1 and anti-PDL1 antibodies exposed to new adverse events including auto-immune diseases whose support is not codified. Questions about treatment duration and criteria evaluation are not resolved. These treatments pave the way for immunomodulation in NSCLC treatment.

Lung hernias are rare and their pathogenesis is few described. They are defined as the protrusion of lung parenchyma through the chest wall: intercostal space, inter-costo-clavicular, supra-clavicular or diaphragmatic hiatus. Lung hernias are classically divided into congenital and acquired hernias. ⋯ Major risks are lung incarceration and necrosis but also ventilatory distress due to paradoxical respiration, in case of large defect. Treatment is first and foremost surgical but debated and should consider the localization, the size, the length of evolution and the possible infectious context. We report the case of a right basi-thoracic lung hernia induced by a cough fit, in a patient with chronic bronchitis.

Comparative Study
[Pneumonectomy for benign disease: indication and factors affecting the postoperative course].
Pneumonectomy for benign disease is rare but may generate more postoperative morbimortality than when performed for lung cancer. We questioned this assessment and retrospectively reviewed 1436 pneumonectomies and 54 completions of which 82 and 10 performed for benign disease (5.7% and 18.5%, respectively): left n=65 and right n=27. Indications were: post-tuberculosis destroyed lung (n=37), aspergilloma (n=18), bronchiectasis (n=19), infection (n=5), congenital malformations (n=5), inflammatory pseudotumor (n=3), trauma (n=2), post-radiation (n=2) and mucormycosis (n=1). ⋯ Considering patients with fungal infections versus others, mortality was 26.3% (n=5/19) and 2.7% (n=2/74), respectively (P=0.0028). Pneumonectomy for benign disease achieves cure with acceptable mortality and morbidity. However, presence of fungal infection should raise the attention for possibility of increased postoperative risks.

Surgical resection of pulmonary aspergilloma is associated with symptoms control, complications prevention, and improved survival, given that the disease is localized and the patient fit enough to undergo surgery. In these operable forms, the impact of perioperative antifungal therapy remains controversial. The purpose of this study was to analyze the impact of antifungal therapy on postoperative morbidity and overall survival in patients with operable pulmonary aspergilloma. ⋯ Antifungal therapy has no significant impact on postoperative morbidity or long-term survival following surgical resection of pulmonary aspergilloma. Such procedure is associated with acceptable postoperative morbidity and long-term survival.

Interstitial lung disease (ILD) is becoming one of the main causes of death of patients with systemic sclerosis (SSc). The prevalence of ILD associated with SSc (SSc-ILD) varies from 33% to 100% according to diagnostic methods. Clinical features such as dyspnea on exertion, dry cough, and chest pains are not specific and usually late-appearing, implying more specific tests in the diagnostic, prognosis, and follow-up of ILD in patients with SSc. ⋯ Several biomarkers such as surfactant-A (SP-A), -D (SP-D), mucin-like high molecular weight glycoprotein (KL-6), and chemokine CCL-18 have been implicated in SSc-PID. Serum levels of these proteins are correlated with the severity of SSc-ILD, as assessed by HRCT and/or PFT. Finally, alveolar concentration of exhaled nitric oxide can be used to screen SSc patients with high risk of deterioration of respiratory function, in whom immunosuppressant treatment could be useful in preventing the evolution to irreversible lung fibrosis.
