Sinonasal intestinal-type adenocarcinoma in northern Portugal: a woodworker's occupational hazard.

Background: Sinonasal carcinomas (SNC) constitute about 3% of all head and neck carcinomas, squamous cell carcinoma being the most common histologic subtype. Some geographical patterns in incidence are observed, as occupational exposure to wood dust is associated with intestinal-type adenocarcinoma (ITAC).

Aims: This study aims to describe the prevalence and characteristics of sinonasal ITAC cases in a region of northern Portugal with a robust wood industry.

Laryngeal tuberculosis, the great deceiver: A series of 10 cases.

Background: Laryngeal involvement is rare in tuberculosis, representing around 1% of all cases of this infection worldwide. Given the larynx' location in the airway, this form of tuberculosis is of particular importance because it is highly contagious. With our hospital being in a high tuberculosis burden area, we propose to characterize the clinical presentation, evolution, and laryngoscopy findings of a series of laryngeal tuberculosis cases in order to reduce misdiagnosis.

Mutational Spectrum, Ocular and Olfactory Phenotypes of -Related RP-Olfactory Dysfunction Syndrome in a Multiethnic Cohort.

gene mutations are a well-known cause of autosomal recessive retinitis pigmentosa (RP), which was recently associated with olfactory dysfunction. The purpose of this study was to report the molecular spectrum and the ocular and olfactory phenotypes of a multiethnic cohort with -associated RP. A cross-sectional case series was conducted at two ophthalmic genetics referral centers.

The Portuguese version of the RhinoQOL Questionnaire: validation and clinical application.

Introduction: Rhinosinusitis constitutes an important health problem, with significant interference in personal, professional, and social functioning. This study presents the validation process of the Portuguese version of the RhinoQOL, to be used as a routine procedure in the assessment of patients with chronic rhinosinusitis.

Objective: To demonstrate that the Portuguese version of the RhinoQOL is as valid as the English version to measure symptoms and health-related quality of life in chronic rhinosinusitis.
