Unlabelled: Hair loss is a significant and constantly growing social problem among both women and men. Many drugs through their toxic effects on the cells of the hair follicle matrix have an influence on mitotic divisions and the hair growth cycle, leading to anagen or telogen effluvium. Currently, there are more and more publications and clinical studies evaluating the possibility of using methotrexate in the treatment of various types of non-scarring and scarring alopecia, but there is no study of the effect relating to the hair loss with low doses of the drug in other therapeutic indications.
Aim: The aim of the study was to evaluate if methotrexate used in immunomodulatory doses could cause increased hair loss.
Materials And Methods: Data from a survey was analyzed in 68 patients treated with methotrexate at the Department of Dermatology of the Jagiellonian University in Cracow in the years 2015-2018.
Results: Increased hair loss after the beginning of methotrexate administration occurred in 29,4% of the subjects, the majority (60%) were women. More frequent occurrence of general symptoms was perceived among the patients who reported alopecia.
Conclusions: Studied group of patients was relatively small, however, it seems that drug hair loss during methotrexate treatment occurs relatively often.

Hearing loss is highly related to acoustic injuries and mechanical damage of ear tissues. The mechanical responses of ear tissues are difficult to measure experimentally, especially cochlear hair cells within the organ of Corti (OC) at microscale. Finite element (FE) modeling has become an important tool for simulating acoustic wave transmission and studying cochlear mechanics.

Background: Alopecia areata (AA) is a chronic inflammatory disease that affects the hair follicles and sometimes the nails. It usually presents as a single or multiple patches of hair loss on the scalp, but any hair-bearing skin can be involved. AA treatment depends on the severity and extent of the disease.

Cosmetic procedures carry inherent risks of adverse events. Though rarely reported, transient and permanent alopecia are potential complications of these procedures. We report the case of a 35-year-old woman who developed pain and patches of nonscarring alopecia with erythema and edema following aesthetic application of poly-L-lactic acid (PLLA) on the face and along the frontal hairline.

Background: Exosomes are a nanoscale extracellular vesicles derived from different cell types that have been investigated for various clinical applications, including functioning as biomarkers and use as direct therapeutics. Given the role of exosomes in multiple pathophysiologic pathways and potential practical applications, they have garnered significant interest in the scientific community but much is still unknown about their development and use.
Aims: This literature review covers the background, mechanisms of action, use as biomarkers, methods of application, and direct therapeutic applications of exosomes.
