Oral Lichen Planus: Clinical Presentation, Demographic Characteristics, and Risk Factors in a Retrospective Study of 186 Polish Patients.

Lichen planus (LP) is a chronic, recurrent mucocutaneous inflammatory disease that develops due to a disturbed immunological response triggered by endogenous and exogenous factors. To evaluate clinical presentation, demographic characteristics, and risk factors in a cohort of Polish patients with oral lichen planus (OLP). Medical records of 186 patients with OLP referred to the student outpatient clinic in Poznań University of Medical Sciences from 2013 to 2023 were analyzed in order to establish clinical presentation, patient's demographic characteristics, and risk factors for OLP.

Dancing is inevitably associated with kinesthetics of the body, including movements, gestures, poses, jumps, turnings, transferring body weight, etcetera. Thus, dance is a manifestation of an amateur or the skilled behavior of a fully trained athletic performance.

Integrated circuits protection with the Langmuir-Blodgett Films.

Integrated circuits (ICs) can be protected from the environment with the encapsulating polymer layer. Protection properties of such a polymer barrier-layer depend strongly from the structure of thin region where polymer stays in direct contact with the IC surface. One of the interesting questions is how thick should this interphase film be to assure good environmental protection to the IC conductor lines, preventing from their corrosion and failure.
