Effects of photobiomodulation and bethanechol chloride treatment on salivary composition and flow rate in head and neck cancer patients undergoing radiotherapy: longitudinal interventional experimental clinical study.

Objective: To evaluate the efficacy of photobiomodulation therapy (PBMT) and bethanechol chloride (BC) on the quantity and quality of saliva in patients undergoing radiotherapy (RT) for head and neck cancer.

Methods: Saliva samples were collected from patients before and after RT, who were treated with PBMT or BC. Clinical parameters, including salivary flow rate (SFR), pH, xerostomia, and concentrations of macro and microelements in saliva, were assessed.

Surgical-related Morphological Characteristics of Sphenoid Sinuses: A Comprehensive CT-Based Analysis.

Background: This study aims to assess the relationships between sphenoid sinus (SS) types, septation, lobulation, symmetry, septal deviation, and the variations in SS pneumatization regarding the surrounding neurovascular structures using Computed tomography (CT) images. Sexes and age groups were investigated.

Material And Methods: We retrospectively evaluated head CT-scans of 320 patients (age range 18-49 years); mean of 43.

Intestinal Parasitic Infections in Children: A 10-Year Retrospective Study.

Background and objective Intestinal parasitic infections are a major public health concern, especially in low-income regions with poor sanitation. Our hospital caters to a large migrant population, but data on these infections in Portugal is limited. This study aimed to assess the prevalence and characteristics of intestinal parasitic infections in pediatric patients from epidemiological, clinical, and microbiological perspectives.

Clinical outcomes of COVID-19 in patients with liver cirrhosis - a propensity-matched analysis from a multicentric Brazilian cohort.

Background: Cirrhosis has been pointed out as a clinical entity that leads to worse clinical prognosis in COVID-19 patients. However, this concept is controversial in the literature. We aimed to evaluate clinical outcomes by comparing patients with cirrhosis to those without cirrhosis in a Brazilian cohort.

Unveiling degenerative bone changes in the condyle: a texture analysis approach using cone-beam computed tomography.

Purpose: The degenerative joint disease is a temporomandibular disorder. By analysing texture parameters, it becomes possible to characterize and differentiate various tissues, based on their textural properties according to cone-beam computed tomography (CBCT). This study evaluated degenerative diseases in the temporomandibular joint through texture analysis.
