Tracheal Stenosis After Prolonged Intubation Due to COVID-19.

Objectives: The authors aimed to evaluate the characteristics and management outcomes of patients who developed tracheal stenosis after invasive mechanical ventilation (IMV) due to COVID-19.

Design, Setting, And Participants: The data of 7 patients with tracheal stenosis and 201 patients without tracheal stenosis after IMV due to COVID-19 between March 2020 and October 2021 were retrospectively analyzed.

Interventions: Flexible bronchoscopy was performed for the diagnosis of tracheal stenosis and the evaluation of the treatment's effectiveness, and rigid bronchoscopy was applied for the dilatation of tracheal stenosis.

The role of interventional pulmonology for the postoperative bronchopleural fistula.

Background: : Postoperative bronchopleural fistula (BPF) remains a serious complication due to its high morbidity and mortality. Although various endoscopic techniques have been defined for the closure of BPF previously, no standard algorithm yet exists.

Aims: To study the effectiveness and safety of various endoscopic procedures in an interventional pulmonology unit.

Association Between Titration Method and Outcomes of First Night Satisfaction and CPAP Compliance.

Introduction: The gold standard therapy for obstructive sleep apnoea syndrome (OSAS) is continuous positive airway pressure (CPAP). Our study evaluated the relationship between first night satisfaction and CPAP compliance, and the effect of using the titration method in this relationship.

Methods: Between January 2012 and December 2012, 40 patients with the diagnosis of OSAS and without comorbidities, who had undergone CPAP titration, were included.

Air embolism following removal of hemodialysis catheter.

Introduction: Air embolism (AE) is a rare, but serious complication that can occur in the practice of hemodialysis. In contrast to careful techniques and meticulous care during insertions and manipulations of the central catheters, awareness of the risk of AE following catheter removal is less. We aimed to analyze the clinical characteristics of the all case reports with AE after catheter removal and summarize the mechanisms, clinical consequences, treatment and prevention of AE.

Placement of self-expandable bifurcated metallic stents without use of fluoroscopic and guidewire guidance to palliate central airway lesions.

Background: Self-expandable metallic stents (SEMS) can be used to treat malignant obstructions and fistulas of the central airways. SEMS can be placed using different methods. Recently, a rigid bronchoscope has been used for stent placement without the need for fluoroscopy.

Bronchoscopic palliation to treat endobronchial metastasis of the tracheobronchial tree.

Background: Endobronchial metastases (EBM) are rarely observed, but they are caused by a number of different tumors. Bronchoscopy is the main approach for both differential diagnosis and to maintain endoluminal palliation. In this study, consecutive EBM cases that had been diagnosed and treated were evaluated in a retrospective cohort.

Heat Shock Proteins, L-Arginine, and Asymmetric Dimethylarginine Levels in Patients With Obstructive Sleep Apnea Syndrome.

Objective: Vascular endothelial inflammation and enhanced oxidative stress are important factors in the pathogenesis of obstructive sleep apnea syndrome (OSAS). The aim of this study was to determine the levels of heat shock protein (HSP) 27, HSP70, HSP90, L-arginine, and asymmetric dimethylarginine (ADMA) in patients with OSAS and determine their relationship with cardiovascular (CV) risk factors.

Material And Methods: Forty patients with OSAS, comprising 26 with and 14 without traditional CV risk factors (obesity, hypercholesterolemia, diabetes, hypertension, and smoking), and 20 control subjects without OSAS were included.

Application of non-invasive mechanical ventilation in an asthmatic pregnant woman in respiratory failure: a case report.

The use of non-invasive mechanical ventilation (NIV) during an asthma attack is controversial. We report a case of a 28-year-old female patient in her 16th week of pregnancy with community-acquired pneumonia who presented during an asthma attack, which led to hypoxic respiratory failure. She was successfully treated using NIV.

High risk of malignant mesothelioma and pleural plaques in subjects born close to ophiolites.

Background: Ophiolites, a special sequence of geologic rock units, are known sources of naturally occurring asbestos. The aim of this study was to test whether the occurrence of malignant mesothelioma (MM) or pleural plaques (PPs) in the province of Sivas, Turkey, is determined by the proximity of the patient's birthplace to ophiolites and, if so, to establish the magnitude of the risk.

Methods: The birthplaces of patients with MM or PPs (cases) and patients with prostate or breast cancer (control subjects), diagnosed between 2000 and 2010 and identified through a mandatory cancer registry or from hospital records (PPs), were located on a geologic map, and the nearest distance to ophiolites was measured.
