Pleomorphic adenoma of the trachea is a rare benign tumor, often challenging to diagnose due to nonspecific symptoms. We report a case of a 72-year-old female with a 10-year history of presumed bronchial asthma, presenting with persistent dyspnea. Preoperative assessment for breast cancer surgery revealed severe obstructive ventilatory impairment.

Rationale And Objectives: Severe COVID-19 typically results in pulmonary sequelae. However, current research lacks clarity on the differences in these sequelae among various clinical subtypes. This study aimed to evaluate the changing lung imaging features and predictive factors in patients with COVID-19 pneumonia in northern China over a 12-month follow-up period after the relaxation of COVID-19 restrictions in 2022.

An understanding of intracellular mechanisms by which fentanyl and other synthetic opioids exert adverse effects on breathing is needed. Using freely moving adult male guinea pigs, we administered the nitric oxide synthase (NOS) inhibitor, L-NAME (N-nitro-L-arginine methyl ester), to determine whether nitrosyl factors, such as nitric oxide and S-nitrosothiols, play a role in fentanyl-induced respiratory depression. Ventilatory parameters were recorded by whole body plethysmography to determine the effects of fentanyl (75 μg/kg, IV) in guinea pigs that had received a prior injection of vehicle (saline), L-NAME or the inactive D-isomer, D-NAME (both at 50 μmol/kg, IV), 15 min beforehand.

To compare the outcomes of tracheostomised COVID-19 patients with non-COVID-19 tracheostomised patients to identify factors influencing severity and mortality. A retrospective, single-centre cohort study was conducted on COVID-19 tracheostomised patients admitted from May 2020 to February 2022, compared with a cohort of non-COVID-19 tracheostomised patients. COVID-19 tracheostomised patients had a higher mortality rate (50% vs.

Asthmatic children who tested positive for COVID-19 experienced changes in lung function and persistent symptoms following SARS-CoV-2 infection, even for several months after diagnosis, and with the same features as in an acute phase. This study aimed to analyze a pediatric age group (between 0 and 17 years old) diagnosed with asthma, and SARS-CoV-2 infection attending regular monitoring visits in a Pediatric Department of a Regional Tertiary Hospital (Filantropia Clinical Municipal Hospital Craiova, Romania) during the COVID-19 pandemic and post-pandemic time interval (i.e.
