Background And Study Objective: Pneumothorax following flexible bronchoscopy (FB) with transbronchial biopsy (TBB) occurs in 1 to 6% of cases. Routine chest radiography (CXR) following TBB is therefore requested by most pulmonologists in an attempt to detect complications, particularly pneumothorax. The objective of this study was to determine if routine CXR after bronchoscopy and TBB is necessary.
Patients And Method: The study group included 350 consecutive patients who underwent FB with TBB at our institution between December 2001 and January 2004. Routine CXR was performed up to 2 h after the procedure in all cases. Additionally, the following information was recorded in all patients: sex, age, immune status, indication for bronchoscopy, total number of biopsies done, segment sampled, pulse oxygen saturation, and development of symptoms suggestive of pneumothorax.
Results: Pneumothorax was diagnosed radiologically in 10 patients (2.9%). Seven patients had symptoms strongly suggestive of pneumothorax prior to CXR, including four patients with large (> 10%) pneumothorax. The other three patients were asymptomatic, with only minimal pneumothorax (
Conclusions: We conclude that routine CXR after bronchoscopy with TBB is necessary only in patients with symptoms suggestive of pneumothorax. In asymptomatic patients, pneumothorax is rare and usually small, so routine CXR is not necessary in this category of patients.

The coronavirus disease 2019 (COVID-19) pandemic had significant global health impact. Like systemic autoimmune diseases, COVID-19 may manifest with systemic and heterogenous clinical presentations. This study aimed to evaluate the prevalence of autoimmune rheumatic manifestations among a cohort of Egyptian patients with COVID-19 infection.

Drug-induced sleep endoscopy (DISE) is performed widely, and several studies have demonstrated its validity as it provides clinical information not available by routine clinical inspection alone. This study aims to evaluate the role of transoral drug-induced sleep endoscopy (DISE) in the evaluation of tongue-palate (TP) interaction and its impact on surgical outcomes. A total of 42 patients with known obstructive sleep apnea syndrome (OSAS) were classified into two groups according to TP interaction (the absence of space between tongue and palate with the visual impression that the tongue is pushing the soft palate) into +ve and -ve TP interaction.

Immunotherapy is improving the survival of patients with metastatic non-small cell lung cancer (NSCLC), yet reliable biomarkers are needed to identify responders prospectively and optimize patient care. In this study, we explore the benefits of multimodal approaches to predict immunotherapy outcome using multiple machine learning algorithms and integration strategies. We analyze baseline multimodal data from a cohort of 317 metastatic NSCLC patients treated with first-line immunotherapy, including positron emission tomography images, digitized pathological slides, bulk transcriptomic profiles, and clinical information.

Introduction: This study aimed to assess current practice in general x-ray rooms in three Irish hospitals. Evaluating the extent to which x-ray protocols are currently standardised can be considered as a preparatory step towards the larger goal of implementing optimisation in a diagnostic radiology department.
Methods: Data on various aspects of general x-ray room exposures was manually collected and analysed to highlight variations with exposure factors in use and workload distribution across each of the ten hospital x-ray rooms included in the study.
