RESUMEN
Background: The COVID-19 pandemic has shifted healthcare from physical in-person patient visits to teleconsultations in order to curtail the spread of this virus. Dermatology, being a visual science, lends itself amenably to teleconsultation. Objective: This study was performed to assess the basic dermatological diseases which are more easily diagnosable and managed through teleconsultation, distinguishing them from diseases for which a face-to-face consultation may be a better option and to delineate the factors affecting the image quality which is the cornerstone of a teledermatology consultation. Methods: A retrospective observational study was conducted over a three-month period during the pandemic. Store and forward, video conferencing, and hybrid consultations were included. Two dermatologists of different clinical experience independently assessed the clinical photographs of the patients and gave each photograph an objective score (Physician Quality Rating Scale) and a diagnosis. The diagnostic concordance between the two dermatologists as well as the correlation of this score with the certainty of diagnosis was calculated. Results: A total of 651 patients completed the study. Mean PQRS score of Dermatologist 1 was 6.22 while the mean score of Dermatologist 2 was 6.24. Patients in whom both the dermatologists were absolutely certain about their diagnosis had a higher PQRS score and interestingly had a higher education level than the rest. There was 97.7 percent diagnostic concordance between the two dermatologists. Infections, acne, follicular disorders, pigmentary disorders, tumors, and STDs had the largest proportion of cases wherein both the dermatologists were in total agreement with each other. Conclusion: Teledermatology might be best for the care of patients with characteristic clinical presentation or for follow-up of already diagnosed patients. It can be used in the post-COVID era to triage patients requiring emergency care and reduce patient wait times.
RESUMEN
INTRODUCTION: Platelet-rich plasma (PRP) is an autologous blood product which has recently been used in multiple spheres of dermatology including facial rejuvenation, androgenetic alopecia, acne scars, and wound healing. Its use in melasma is comparatively an understudied topic. MATERIAL AND METHODS: An extensive systematic literature search of the PubMed electronic database and Cochrane central register of controlled trials was done using the keywords "platelet rich plasma" and "melasma" in the title. Relevant studies were selected and data were analyzed by two different authors. Four articles were excluded as they did not adhere to the inclusion criteria of this review and a total of 6 articles were reviewed.The relevant references of the included articles were also traced and included. DISCUSSION: These studies showed that PRP has been used effectively not only as an adjuvant therapy but also as a standalone treatment for melasma. PRP contains about 30 growth factors, transforming growth factor beta (TGF-ß) being one of the growth factors having a predominant role in treatment of melasma. TGF-ß decreases signal transduction of microphthalmia-induced transcription factor and thus decreases tyrosinase and tyrosinase-related proteins. In addition to this, PRP also has an additional benefit of inducing collagen synthesis thus improving the quality and texture of the skin. But there is a scarcity of data and large randomized controlled trials. This review is an effort to highlight and upscale the use of this excellent blood product for melasma which is quite a treatment refractory disorder.

Platelet rich plasma (PRP) is an upcoming interventional therapy for the treatment of melasma. Its efficacy is due to the multiple growth factors present in it which decrease melanogenesis by various signal transduction pathways. The present study evaluated the efficacy of PRP as a standalone agent in treatment of melasma. This is an open labeled prospective trial. Forty patients were given intralesional PRP at once monthly interval. Three such PRP sessions were carried out and the patients were followed up for 3 months. Assessment was done by calculating the modified melasma area severity index score (mMASI) for each patient. Patients were also asked to self-evaluate their improvement based on a scale. There was an average 54.5% reduction in the mMASI score at the end of the study. There was no relapse in any patient. This reduction was irrespective of the skin type, gender, and type of melasma. Patients self-evaluation showed that more than 90% of the patients were pleased or very pleased with the results. There were no significant side effects. PRP appears to be a potential new therapy with significant efficacy in improving pigmentation of melasma, standalone as monotherapy.

Mantle cell lymphoma is a rare form of B-cell non-Hodgkin's lymphoma that presents as a low-grade lymphoma and has a different prognosis than other types of lymphoma. Mantle cell lymphoma is an aggressive tumor that can manifest as nonspecific symptoms, such as nasal obstruction, dyspnea, and erythematous indurated cutaneous plaques. Diagnosis can be established with confidence using immunohistochemistry. In this report, a case of nasopharyngeal mantle cell lymphoma metastasizing to the skin is discussed.
RESUMEN
Background: Dermatophytes are keratinophilic fungi responsible for skin, nail, and scalp infections. Chronic dermatophytosis, defined as persistent infection for six months or more, was very rare in the 1980s and mostly limited to patients with nail involvement, but this is no longer true. Currently, patients with chronic dermatophytosis are increasing, and about 50 percent of patients with dermatophytosis have at least one other member of their family infected at the same time, sometimes with entire families being affected at once. Objective: We sought to study the possible risk factors associated with familial dermatophytosis. Methods: The present questionnaire-based study was conducted from May 2017 to July 2017. Patients with a clinical diagnosis of dermatophytosis and at least one other family member affected were included. A proforma was filled and history was taken, including number of family members affected, site of infection in the index case, site(s) of infection of all other subsequent family members affected, and use of over-the-counter drugs. Results: Out of the 113 families surveyed, which included 673 subjects, a little over half (55.4%) were affected by dermatophytosis. In 103 families, the initial site of infection in the subsequent family member affected was the same site as that affected in the first member. All families reported a history of using an irritant soap and over-the-counter drugs. Washing all the family's clothing together was a common factor. All families had a single bathroom and used the same soap and stool for bathing. Conclusion: Through our survey, we identified possible risk factors that might be responsible for the increasing epidemic of familial dermatophytosis in India, including sharing of soaps and towels, washing clothes in the same vessel, sharing of lavatories, abuse of topical steroids and over the counter topicals, and use of antiseptic soaps that kill normal flora.
RESUMEN
Lucio phenomenon (LP) is a rare reactional state seen in cases of diffuse lepromatous leprosy. Lucio leprosy is a pure, primitive, and diffuse form of lepromatous leprosy. It is observed almost exclusively in Mexico and Central America and is considered a globally restricted phenomenon. However, isolated cases are being reported worldwide. Patients with Lucio leprosy often present with manifestations of LP, which includes purpuric macules with multiple and extensive areas of ulceration with bizarre-patterned, angulated borders mainly affecting the extremities. LP is difficult to recognize, especially in nonendemic countries, which can lead to a delay in its diagnosis and management. We report a case of LP due to its occurrence in the classical form of lepromatous leprosy and rarity in North India.

Hair transplantation, a generally regarded as a safe surgical modality for the treatment of androgenetic alopecia, is not without its potential risks and complications. A case of an extensive keloid formation at donor site following follicular unit extraction is discussed. Hair transplant surgeons should be aware of this significant potential complication, especially in patients having previous keloidal tendencies to avoid such disastrous outcomes.
