Laryngeal Cancer: Epidemiology, Etiology, and Prevention: A Narrative Review.

Laryngeal cancer comprises 30%-40% of head and neck malignancies, and it is the most common malignancy in otolaryngology. The main risk factors for laryngeal cancer are tobacco use, excessive alcohol consumption, gastroesophageal reflex, Plummer-Vinson syndrome, exposure to heat, chemicals, and some viral infections. This literature review summarizes all known data over the past decade with an assessment of the main etiological factors related to cancer incidence, general measurement issues in the cancer epidemiology and the current state of science in relation to laryngeal cancer.

[Disturbances of nasal aerodynamics in patients with the curved nasal septum and the rationale for its surgical correction].

Serious disturbances of nasal aerodynamics contribute to the development of diseases of the broncho-pulmonary apparatus. The early recognition of ventilation problems in patients with the curved nasal septum is paramount for the efficacious prevention and treatment of respiratory complications. The authors describe principles of rhinosurgical correction of affected nasal aerodynamics in patients with the curved nasal septum.

[Clinicocytological assessment of nasal mucosa and buccal epithelium in coal miners].

The aim of the study was cytomorphological examination of the cells of nasal mucosa and buccal epithelium in coal miners. Two groups of miners were examined: non-exposed and exposed to industrial dust. It was found that coal dust inhalation provokes dystrophic processes in the upper airways, impairs intracellular regeneration resulting in atrophic changes in nasal mucosa epithelium.

[Indicators of the activity of the immune system during laser therapy of vasomotor rhinitis].

Helium-neon laser LH-75 was used to treat 60 inbred mice and 62 patients with vasomotor rhinitis. The patients were given 10 laser sessions. In animals, all responses of T-lymphocytes were modified.
