Publication Melatonin - A Cutaneous Perspective(Society of Dermatologists, Venereologists and Leprologists of Nepal (SODVELON), 2021) Dhali, Tapan; Sharma, Mona; Hemrajani, PriyankaAbstract: Melatonin (MLT) is an endogenous hormone secreted from the pineal gland, located deep in the brain in the epithalamus associated with numerous biological activities. The primary function of melatonin is to regulate sleep-wake cycles. However, research over the last few years has enlightened a range of functions associated with this molecule, including anti-inflammatory, direct and indirect antioxidant activity, regenerative tissue benefits, and preservation of mitochondrial function. Melatonin’s anti-inflammatory and antioxidant support, coupled with its mitochondrial modulation, makes it a vital molecule to use for skin health homeostasis. The cutaneous melatoninergic system’s widespread expression and pleiotropic activity provides for a high level of cell-specific selectivity. Several skin cells, including normal and malignant keratinocytes, melanocytes, fibroblasts and hair follicles, express melatonin receptors. Melatonin also has receptor-independent effects that protect against oxidative stress and can reduce ultraviolet radiation-induced damage. Several functions of melatonin in the skin have been experimentally implicated such as hair growth cycling, fur pigmentation, melanoma control, suppression of ultraviolet-induced damage to the skin cell. Melatonin may play a role in treating several dermatoses e.g., atopic eczema, psoriasis, melasma, ulcer healing, and malignant melanoma. There is a plethora of functional melatonin properties, which still await to be fully appreciated by dermatologists. The current review emphasizes few of the established uses and few emerging potentialities that render melatonin a promising candidate for managing several diseases.Publication Study of Correlation of Severity and Quality of Life in Patients with Congenital Ichthyosis(Society of Dermatologists, Venereologists and Leprologists of Nepal (SODVELON), 2022) Hemrajani, Priyanka; Sharma, Mona; Dhali, Tapan; B.C, Sharath KumarAbstract: Introduction: Congenital ichthyosis is a disorder of cornification of skin with various cutaneous symptoms. Quality of life is a subjective perception of patients regarding their disease status and treatment received. Dermatological disorders have poor quality of life associated with them as any other systemic disease. Objective : The present study was conducted to assess the quality of life among patients of congenital ichthyosis, so that suitable remedial measures may be devised based on the same. Materials and Methods: It was a hospital based cross-sectional study with total 120 patients enrolled for study duration of one year .Children’s Dermatology Quality Life Index (CDLQI) questionnaire was used to assess the quality of life among patients. Global disease severity scale and VAS scale for severity of ichthyosis was used along with recording of socio-demographic details. Results: With a response rate of 87%, the sample size comprised of 104 subjects, aged between 0-15 years. Females outnumbered the sample by more than 2/3rd. ‘Symptoms and feelings’ was the most affected domain in the CDLQI. Itching, female gender and presence of scales were significant predictors of poor quality of life scores. Conclusion: The present study shows the epidemiological correlation of patients with congenital ichthyosis and the predictors of poor quality of life score. Regular subjective assessment of quality of life among patients should be included in routine clinic visits, as counselling plays a very important role in these patients.
