Background: According to guidelines for the diagnosis and treatment of interstitial lung diseases (ILDs), a diagnostic surgical lung biopsy should be used to obtain the differential diagnosis of an ILD in patients with ILDs, which are difficult to distinguish clinically. However, the risk of developing postoperative complications such as postoperative pulmonary fistula or acute exacerbation is a concern. The purpose of this study was to evaluate the safety of surgical lung biopsy for the differential diagnosis of ILDs.
Methods: From October 2007 to July 2019, 129 patients thought to have ILD underwent a surgical lung biopsy at Toho University Omori Medical Center. We conducted a retrospective study on the diagnosis and safety of surgical lung biopsy for patients with ILD.
Results: The 30- and 60-day mortality was 0%. Postoperative complications occurred in 13 of 129 (10.1%) patients. The complications included pneumothorax in 8 (6.2%) patients after removal of the chest tube, postoperative pneumonia in 2 (1.0%), and acute exacerbation in 1 (0.8%). Postoperative pneumothorax was observed in 4 of 13 patients (30.7%) who underwent a biopsy of the apex of the lung (right S1, left S1+2), which was a significantly higher rate of postoperative pneumothorax than seen for patients undergoing biopsy at other sites (P=0.0086).
Conclusions: Surgical lung biopsy for the differential diagnosis of an ILD was performed safely. However, biopsy sites for ILDs need to be carefully selected to avoid postoperative complications.

Small pulmonary nodule localization techniques in the era of lung cancer screening: a narrative review.
Int J Surg
January 2025
Carcinoma Department of Traditional Chinese Medicine, Dianjiang People's Hospital of Chongqing, Chongqing, PR China.
The widespread adoption of high-resolution computed tomography (CT) screening has led to increased detection of small pulmonary nodules, necessitating accurate localization techniques for surgical resection. This review examines the evolution, efficacy, and safety of various localization methods for small pulmonary nodules. Studies focusing on localization techniques for pulmonary nodules ≤30 mm in diameter were included, with emphasis on technical success rates and complication profiles.

Purpose Of Review: This narrative review discusses the mechanisms connecting gut dysbiosis to adverse clinical outcomes in critically ill patients and explores potential therapeutic strategies.
Recent Findings: In recent years, the study of microbiota in ICUs has gained attention because of its potential effects on patient outcomes. Critically ill patients often face severe conditions, which can compromise their immune systems and lead to opportunistic infections from bacteria typically harmless to healthy individuals.
Update on Pulmonary Toxicity Induced by New Breast Cancer Treatments.

GOIRC (Gruppo Oncologico Italiano di Ricerca Clinica), Parma, Italy.
In recent years, new anticancer drugs have been investigated and approved for the treatment of breast cancer based on improved survival outcomes. However, these new treatments have specific class-related side effects. Pulmonary toxicity has been identified as an adverse event of special interest with everolimus, and is becoming an increasingly significant clinical challenge with the recent approval of trastuzumab deruxtecan.

Papillary fibroelastomas (PFEs) are rare, benign, primary cardiac tumors, typically found on the valve surfaces and more commonly on the left side of the heart, with occurrences in the right atrium even rarer. In this case, a highly mobile tumor was incidentally detected in the right atrium of an 83-year-old woman with advanced right lung cancer during preoperative transthoracic echocardiography and magnetic resonance imaging. Although the patient was asymptomatic and of advanced age, the tumor's high mobility warranted resection.

Background: Circulating tumor cells and clusters (CTC) from soft-tissue sarcoma (STS) that become entrapped in the lung can form micro-metastases and lead to pulmonary metastatic disease. Many patients with localized high-risk STS later develop metastases. Radiation is effective at reducing local recurrence by eradicating microscopic infiltration and satellites in the reactive zone surrounding the primary tumor.
