RESUMO

INTRODUCTION: Artificial intelligence (AI) has an important role to play in future healthcare offerings. Machine learning and artificial neural networks are subsets of AI that refer to the incorporation of human intelligence into computers to think and behave like humans. OBJECTIVE: The objective of this review article is to discuss perspectives on the AI in relation to Coronavirus disease (COVID-19). METHODS: Google Scholar and PubMed databases were searched to retrieve articles related to COVID-19 and AI. The current evidence is analysed and perspectives on the usefulness of AI in COVID-19 is discussed. RESULTS: The coronavirus pandemic has rendered the entire world immobile, crashing economies, industries, and health care. Telemedicine or tele-dermatology for dermatologists has become one of the most common solutions to tackle this crisis while adhering to social distancing for consultations. While it has not yet achieved its full potential, AI is being used to combat coronavirus disease on multiple fronts. AI has made its impact in predicting disease onset by issuing early warnings and alerts, monitoring, forecasting the spread of disease and supporting therapy. In addition, AI has helped us to build a model of a virtual protein structure and has played a role in teaching as well as social control. CONCLUSION: Full potential of AI is yet to be realized. Expert data collection, analysis, and implementation are needed to improve this advancement.

RESUMO

BACKGROUND: Acne is a chronic inflammatory skin disease which involves the pilosebaceous unit. Tissue inflammation isone of the crucial mechanisms, amongst others. Of the various cytokines, leukotriene B4 (LT-B4) is the most potentleucocyte chemotactic mediator. Montelukast is an antagonist of the LT-B4 receptor. Finasteride is an antiandrogen whichspecifically inhibits the 5α-reductase enzyme. AIMS: This study aimed at comparing the efficacy, tolerability and safety of montelukast versus finasteride in the treatmentof moderate acne in women. PATIENTS/METHOD: This randomized, single-blinded, prospective trial over 12 weeks recruited 65 female subjects with moderate acne vulgaris (Global Acne Grading System Scale) for evaluation. One group (n = 30) received oral montelukast (10 mg PO daily), while the second group (n = 25) received oral finasteride (2.5 mg PO daily) in combination with topical clindamycin 2% solution. Lesion count and acne severity were evaluated at time intervals of 0 (baseline), 4, 8, and 12 weeks. Adverse effects of the drugs were noted. RESULTS: Both lesion count and severity of acne decreased significantly after treatment in both the groups as compared to the baseline. The acne severity score reached from 33.93 in time zero to 20.6 in the 12th week and 35.71 at baseline to 16.43 at the end of treatment in the Montelukast and Finasteride groups, respectively. Side effects were noted in 3 patients and 2 patients in the monteleukast and finasteride group, respectively, which were transient and non-serious in nature proving the satisfactory tolerability and safety of these two drugs. CONCLUSION: The results of this study show that both montelukast and finasteride have good efficacy in the treatment of acne. Finasteride has more efficacy than montelukast for treating moderate acne in normo-androgenic women.

RESUMO

BACKGROUND: Dermoscopy has been shown to be a useful supportive tool to assist the diagnosis of several non-neoplastic dermatoses (i.e. inflammatory, infiltrative and infectious skin diseases), yet data on skin of colour is still limited. OBJECTIVES: To characterize dermoscopic features of non-neoplastic dermatoses in dark-skinned patients in order to identify possible clues that may facilitate the differential diagnosis of clinically similar conditions. MATERIALS & METHODS: Members of the International Dermoscopy Society were invited to submit cases of any non-neoplastic dermatosis developing in patients with Fitzpatrick Phototypes V-VI whose diagnosis had been confirmed by the corresponding gold standard diagnostic test. A standardized assessment of the dermoscopic images and a comparative analysis according to clinical presentation were performed. Seven clinical categories were identified: (I) papulosquamous dermatoses; (II) facial hyperpigmented dermatoses; (III) extra-facial hyperpigmented dermatoses; (IV) hypopigmented dermatoses; (V) granulomatous dermatoses; (VI) sclerotic dermatoses; and (VII) facial inflammatory dermatoses. RESULTS: A total of 653 patients (541 and 112 with Phototype V and VI, respectively) were recruited for the analysis. Thirty-six statistically significant dermoscopic features were identified for papulosquamous dermatoses, 24 for facial hyperpigmented disorders, 12 for extra-facial hyperpigmented disorders, 17 for hypopigmented disorders, eight for granulomatous dermatoses, four for sclerotic dermatoses and 17 for facial inflammatory diseases. CONCLUSION: Our findings suggest that dermoscopy might be a useful tool in assisting the diagnosis of clinically similar non-neoplastic dermatoses in dark phototypes by revealing characteristic clues. Study limitations include the retrospective design, the lack of a direct dermoscopic-histological correlation analysis and the small sample size for less common diseases.

RESUMO

Acne scars are the reason for significant morbidity among dermatology outpatients. With more modalities being introduced every year, it is important to choose the best one suited for a particular type of scar for each patient to obtain an optimum result. Guidelines on acne scar management in the skin of color are not available where the therapeutic effect and side effect profile of the modalities can vary significantly. This narrative review looked at critical evaluation of the available modalities to find the level of evidence and therapeutic ladder of management of different types of acne scars. Treatment options for different types of scars have been described. Evidence level for each type of modality for the individual type of scar was calculated using the Strength of Recommendation Taxonomy (SORT) developed by editors of the US family medicine and primary care journals. In addition, various newer and emerging treatment options, such as dermal cell suspension, jet volumetric remodeling, and radiofrequency subcision, have been discussed. The highest level of evidence is available for microneedling, fractional radiofrequency, fractional CO2, and erbium:yttrium aluminum garnet laser for mild to moderate grade scars. Trichloroacetic acid chemical reconstruction of skin scars showed efficacy in ice pick scars. Grade 4 scars improve poorly with resurfacing procedures, where punch excision and punch elevation can be tried. Platelet-rich plasma therapy was effective in combination with lasers and microneedling. Overall there is lack of high-quality data in the management of post acne scars. Combination treatment has shown better efficacy compared to single modalities.

RESUMO

PURPOSE: To evaluate the efficacy and safety of short-course low-dose oral prednisolone in symptomatic pityriasis rosea (PR) of onset <5 days and compare it with placebo. MATERIAL AND METHODS: Placebo-controlled randomized double-blind study design with the treatment group receiving tapering doses of oral prednisolone over 2 weeks and the control group receiving a placebo. Outcome measures evaluated were subsidence of patient-perceived pruritus, improvement in rash quantified by a specific score, adverse effects and relapse at 12 weeks. RESULTS: The improvement in the pruritus score as well as objective rash score were much better in the prednisolone-treated group. No adverse effects reported in either group. The relapse rate at 12 weeks was much higher in the prednisolone treated group. CONCLUSIONS: Oral corticosteroids, even if used in low-dose and for a short tapering course should not be the first line of therapy for PR. The only justified indication may be extensive and highly symptomatic lesions of PR.
