Clinical characteristics of acute rhinosinusitis in COVID-19 a post hoc analysis of a longitudinal study.

Background: Acute rhinosinusitis (ARS) is a common and well-defined disorder, primarily of viral aetiology, with rhinovirus and coronavirus accounting for more than 50% of viral ARS. The fight with COVID-19 pandemic resulted in an increased availability viral testing, which in turn allowed testing for presence of SARS-Cov-2 in all patients presenting common cold (or ARS) symptoms. The aim of this study was to assess the clinical characteristics of acute rhinosinusitis in patients diagnosed with COVID-19.

Cancer Stem Cell Markers in Rhabdomyosarcoma in Children.

(1) Background: The aim of the present study was to assess the cancer stem cell (CSC) markers CD24, CD44, CD133, and ALDH1A1 in rhabdomyosarcoma (RMS) in children and to define their prognostic role in this group of patients. (2) Methods: The study material was archival tissue specimens collected from 49 patients under 18 years of age and who had been diagnosed with RMS. Immunohistochemistry (IHC) was used to evaluate the expression of the selected CSC markers in the tumor tissue.

Oral cavity morphology among children at risk of sleep disordered breathing.

Purpose: The aim of this study was to evaluate oral cavity morphology in children at risk of sleep disordered breathing (SDB).

Methods: The study included children 3-17 years of age. The risk of SDB was evaluated using the paediatric sleep questionnaire (PSQ); afterwards, children at risk of SDB were enrolled in the study group.

Orbital decompression for thyroid eye disease: surgical treatment outcomes in endocrinological assessment.

Introduction: Surgical orbital decompression involves removal of one or more of the orbital bony walls in order to gain space for overgrown muscles and adipose tissue, which results in a reduction in pressure on the eye. This observational study aims to perform an endocrinological assessment of the surgical treatment outcomes of thyroid eye disease (TED) patients before and after orbital decompression.

Material And Methods: This retrospective study included 51 TED patients (84 orbits) who underwent endoscopic orbital decompression (EOD) or balanced orbital decompression.

Radiological markers of granulomatosis with polyangiitis with nasal involvement.

Introduction: Granulomatosis with polyangiitis (GPA) is an autoimmune disease leading to necrotizing lesions in the affected tissues. Computed tomography (CT) of paranasal sinuses reveals multiple lesions in patients with GPA, for example, sinus opacification, bone / cartilage destruction, and neoosteogenesis.

Objectives: We aimed to describe and compare CT lesions found in patients with GPA and those with chronic rhinosinusitis (CRS) and to propose a new radiological marker of GPA-nasal strands.
