Current understanding of frictional dermatoses: A review.

Human skin is continually exposed to internal and external forces, dynamic as well as static. The skin is normally flexible and can resist mechanical trauma due to friction, pressure, vibration, suction and laceration to a considerable degree. However, an excess of these forces can abnormally affect the structure and function of the skin, setting the stage for the development of a skin disorder. Repetitive trauma can cause lichenification, hyperpigmentation, erythema, scaling, fissuring, blisters, ulceration and chronic alterations. Frictional dermatoses is an under-recognised entity with no clear-cut definition and encompasses a variety of terms such as frictional dermatitis, frictional melanosis, frictional pigmentary dermatoses and certain other named entities, many of which are confusing. The authors propose to define frictional dermatoses as 'a group of disorders caused by repetitive trauma to the skin as a result of friction of varied aetiology which can have a wide range of cutaneous manifestations depending on the type of insult.' The exact prevalence of frictional dermatoses as a separate entity is unknown. Authors who conducted this review include a group of dermatologists and post graduate students from various institutions. Literature was reviewed through PubMed, Medscape, Medline, ResearchGate and Google Scholar using the terms 'frictional dermatitis,' 'friction and skin,' 'dermatoses and culture,' 'clothing dermatitis,' 'friction melanosis,' 'PPE induced dermatoses in COVID-19 era,' etc. A total of 122 articles were reviewed and 100 articles among them were shortlisted and included in the study, after removing duplications. The review was followed up with further deliberation which resulted in the formulation of a new definition and classification of frictional dermatoses taking into account the morphology, histopathological characteristics, anatomical region affected and the major predisposing factors. The rising incidence of mechanical dermatoses in the COVID-19 era was also emphasised.

Awareness and Attitudes Toward Emergency Contraceptives Among College Students in South India.

BACKGROUND: In India every year, a large number of pregnancies are unplanned resulting in unsafe abortion. This has tremendous implications both on health and survival of women. Usage of emergency contraceptive pills (ECPs) could be a solution provided the usage is as per guidelines and social issues do not cause objections. AIM: This study was done to assess the awareness and attitudes regarding ECPs. METHODS: Data were collected using self-administered questionnaire from the university students. RESULTS: Out of 449 students, 384(85.5 %) had heard about ECPs. The commonest source of information was television 299(77.9 %). Only 128(33.3 %) students knew that ECPs do not help in prevention of STDs. 209(54.4 %) participants knew the correct time frame for taking ECPs. 109(28.4 %) were unaware of its side effects. Only 149(33.2 %) had received reproductive health education (RHE) in the past. The awareness level of students about ECPs was moderate among 231(60.2 %) participants. Awareness was significantly more among males (p = 0.013), students with science background (p = 0.001) and those who had RHE previously (p = 0.043). 219(57 %) had average level of perception toward ECPs. 254(66.2 %) participants favored prescription before procuring ECPs from drug stores. 261(68 %) participants favored information about ECPs to be given in educational institutions, and a majority, 186(48.4 %), said they would recommend ECPs to their friends. Average-to-good perception about ECPs was seen in significantly greater proportion of females (p = 0.034). CONCLUSION: RHE is must at educational institutions so as to promote awareness and to remove misconceptions about ECPs among youth. This would help users in preventing unintended pregnancies and unsafe abortions.
