Management of radiotherapy-induced hyposalivation using photobiomodulation therapy: a case series.

It is not uncommon for individuals receiving radiotherapy for head and cancers to experience dry mouth sensation (xerostomia), salivary hypofunction (hyposalivation) and taste changes. The present study aimed to evaluate the short-term effectiveness of biweekly photobiomodulation therapy (PBMT) in managing these radiotherapy-induced adverse effects and its impact on oral health-related quality of life. Ten patients who developed xerostomia and hyposalivation secondary to radiotherapy for head and neck cancer were included.

Vulvo-Vaginal-Oral Lichen Planus: A Case Report and Literature Review.

Vulvo-vaginal-oral lichen planus (VVO-LP) is a chronic inflammatory condition affecting the mucous membranes of the oral cavity, skin, and genital areas. The exact etiology remains unclear, although immune-mediated mechanisms are considered likely contributors. It is a rare form of lichen planus, which typically presents in adults and is more common in middle-aged women.

Behçet's Syndrome in a Child: A Case Report and a Review of Literature.

Behçet's syndrome is a complex chronic inflammatory disorder characterized by widespread inflammation of the blood vessels, affecting various systems in the body. Although its exact cause remains unknown, genetic predisposition, particularly HLA-B51/B5 gene carriage, and environmental factors are believed to play roles. The disease typically manifests in individuals aged 20-40 years, with an uncommon occurrence in children and elderly individuals.

Molecular Pathway Changes Associated with Different Post-Conditioning Exercise Interventions After Experimental TBI.

Traumatic brain injury (TBI) causes complex, time-dependent molecular and cellular responses, which include adaptive changes that promote repair and recovery, as well as maladaptive processes such as chronic inflammation that contribute to chronic neurodegeneration and neurological dysfunction. Hormesis is a well-established biological phenomenon in which exposure to low-dose toxins or stressors results in protective responses to subsequent higher-level stressors or insults. Hormetic stimuli show a characteristic U-shaped or inverted J-shaped dose-response curve, as well as being time and exposure-frequency dependent, similar to pre-conditioning and post-conditioning actions.

Spinal cord injury disrupts plasma extracellular vesicles cargoes leading to neuroinflammation in the brain and neurological dysfunction in aged male mice.

Aged individuals with spinal cord injury (SCI) are prevalent with increased mortality and worse outcomes. SCI can cause secondary brain neuroinflammation and neurodegeneration. However, the mechanisms contributing to SCI-induced brain dysfunction are poorly understood.
