Impact of COVID-19 Pandemic on Dermatology Teaching Program in India: A Survey on the Faculty and Residents' Perspective.

Background: Impact of COVID-19 pandemic has been immense. An innocent casualty of this disaster is medical education and training. Dermatology, which primarily deals with out-patient services, medical and surgical interventions, and in-patient services, was one of the worst hit. The National Medical Commission of India has implemented competency-based medical education (CBME) in Dermatology, Venereology, and Leprosy since 2019. The new curriculum relies on acquiring practical and procedural skills, training skills in research methodology, professionalism, attitude, and communication. Objectives: The study was undertaken to understand the implications of the COVID-19 pandemic on postgraduate dermatology CBME training in India. Materials and Methods: A questionnaire-based survey was carried out on postgraduate dermatology teachers and residents in India after obtaining ethics committee approval. An online semi-structured English questionnaire was administered by Google Forms. The calculated sample size was 366 dermatology faculty and 341 postgraduate students. Validity (Content validity ratio (CVR) ≥0.56) and reliability (Cronbach's alpha coefficient 0.7249) of the questionnaire were determined. Results: Among the 764 responses received, 51.4% reported that their institutes were converted to exclusive COVID hospitals. Domains of dermatology education affected were procedural training (n = 655), bedside clinical teaching (n = 613), outpatient department-based clinical teaching (n = 487), bedside laboratory procedures (n = 463), research activities (n = 453), histopathology (n = 412), and theory classes (n = 302). To keep up with the teaching-learning process, online platforms were mostly utilized: Zoom Meeting (n = 379), Google Meet (n = 287), and WhatsApp Interaction (n = 224). Teaching during ward rounds was significantly more affected in exclusively COVID institutes than non-exclusive COVID institutes (P < 0.001). Psychomotor skill development suffered a major jolt with 26.7% of respondents reporting a standstill (P < 0.001). Communication skills among students suffered due to social distancing, mask, and poor attendance of patients. According to 23.84% of respondents, formative assessment was discontinued. Conclusion: Online seminars, journal clubs, and assessments have been incorporated during the pandemic. Online modalities should be used as a supplementary method as psychomotor skills, communication skills, research work, and bedside clinics may not be replaced by the e-learning.

Cutaneous ulceration as a presenting feature of type 1 lepra reaction: A case report.

Reactions in leprosy represent sudden shift in the immunological response and are seen in 11-25% of affected patients. It can be seen before, during or after the completion of multidrug therapy (MDT).1 Two types of reactions are recognized; Type 1 reaction (T1R), seen in borderline leprosy, affecting mainly skin and nerves; type 2 reaction (T2R) or erythema nodosum leprosum (ENL), seen in lepromatous leprosy, characterized by systemic features in addition to cutaneous lesions. Trophic ulcers and ulcerating ENL are well known entities while cutaneous ulceration in T1R is extremely rare; we describe an immune-competent woman with cutaneous ulceration as a presenting feature to highlight the need to recognize this entity at the earliest opportunity.

Utility of oral mucosa as a substrate for the serodiagnosis of pemphigus: A descriptive analysis.

BACKGROUND: The indirect immunofluorescence test is useful in the serodiagnosis of pemphigus. As indirect immunofluorescence titers correlate with disease activity in pemphigus, it is often used as a monitoring tool. The sensitivity of indirect immunofluorescence depends on the substrate used, and the preferred substrates are monkey esophagus for pemphigus vulgaris and normal human skin for pemphigus foliaceus. AIMS: We evaluated oral mucosa as a substrate for indirect immunofluorescence in pemphigus. METHODS: Fifty patients with pemphigus (40 with pemphigus vulgaris and ten with pemphigus foliaceus) and 50 controls were enrolled for study. Demographic and clinical details were recorded and indirect immunofluorescence using two substrates (oral mucosa and normal human skin) was carried out in serial dilution. Desmoglein (Dsg) 1 and 3 enzyme-linked immunosorbent assay was also evaluated simultaneously. RESULTS: Indirect immunofluorescence was positive in 40 patients (80%) with oral mucosa substrate and 34 patients (68%) with normal human skin substrate. Circulating antibodies were detected with oral mucosa in 33 (82.5%) of the 40 pemphigus vulgaris patients and in 26 (65%) patients using normal human skin. Antibodies were detected in eight of the ten pemphigus foliaceus patients (80%) with normal human skin and in seven (70%) patients with oral mucosa. Dsg enzyme-linked immunosorbent assay was positive in 45 (90%) patients, and 37 of these were also indirect immunofluorescence positive with oral mucosa. In the five Dsg enzyme-linked immunosorbent assay-negative patients, indirect immunofluorescence with oral mucosa was positive in three. LIMITATIONS: A comparison of oral mucosa with monkey esophagus could not be performed. CONCLUSION: Oral mucosa is a suitable and sensitive substrate for indirect immunofluorescence in pemphigus. Further studies comparing the sensitivity of indirect immunofluorescence using oral mucosa with monkey esophagus are recommended.

Serration pattern analysis as a practical adjunct tool for categorization of subepidermal autoimmune blistering diseases.

BACKGROUND: Serration pattern analysis helps in the classification of subepidermal autoimmune blistering disorders; more precisely, it helps to differentiate epidermolysis bullosa acquisita from other subepidermal autoimmune blistering disorders. Most of the published reports of this tool have come from a single center. OBJECTIVES: The objectives of the study were to study the utility of serration pattern analysis in classifying subepidermal autoimmune blistering disorders. METHODS: Seventy five cases of subepidermal autoimmune blistering disorders were enrolled in this prospective study. A three millimeter punch biopsy was taken from the perilesional skin or mucosa for direct immunofluorescence; indirect immunofluorescence was carried out using salt-split skin. Subclassification of subepidermal autoimmune blistering disorders was done based on direct immunofluorescence, indirect immunofluorescence on salt-split skin, indirect immunofluorescence using knockout skin and serration pattern analysis findings. RESULTS: Indirect immunofluorescence was positive in 68 cases; 14 cases showed a dermal staining pattern while the rest showed either an epidermal or a combined pattern. All patients with epidermal or combined staining patterns showed "n" serrated pattern on direct immunofluorescence. Nine patients with dermal staining on indirect immunofluorescence also revealed an "n" serration pattern on direct immunofluorescence indicating the diagnosis of anti-p200 pemphigoid, and the rest showed a "u" serrated pattern. Three patients with negative indirect immunofluorescence showed "u" serration on direct immunofluorescence while the rest showed "n" serration. LIMITATIONS: ELISA and immunoblotting could not be performed due to resource constraints. CONCLUSION: Based on indirect immunofluorescence and serration pattern analysis, classification of the majority of patients with subepidermal autoimmune blistering disorders was possible in our study. Pattern recognition is a cost-effective tool and can be easily learnt. It is recommended to be practiced in all laboratories where facilities for advanced immunological diagnosis are unavailable.

Epidermolysis bullosa acquisita and anti-p200 pemphigoid as major subepidermal autoimmune bullous diseases diagnosed by floor binding on indirect immunofluorescence microscopy using human salt-split skin.

BACKGROUND: Subepidermal autoimmune bullous diseases are a diverse group of diseases with overlapping clinical and immunopathological features. Indirect immunofluorescence microscopy on artificially split skin helps to classify these conditions into those with staining on the epidermal side of the split ("roof-binding") and those with staining on the dermal side ("floor-binding"). Epidermolysis bullosa acquisita is the prototype of "floor-binding" subepidermal autoimmune bullous diseases. However, not all floor-binding sera are associated with epidermolysis bullosa acquisita. AIM: The aim of this study was to evaluate the clinical and immunological profile of patients with floor-binding subepidermal autoimmune bullous disease by indirect immunofluorescence microscopy and to identify the target antigens in them. METHODS: Ten patients who showed a floor-binding pattern were studied with regard to their clinical and immunopathological characteristics. Target antigens were identified by modified indirect immunofluorescence microscopy using recessive dystrophic epidermolysis bullosa skin, enzyme linked immunosorbent assay, and immunoblotting. RESULTS: Diagnosis of epidermolysis bullosa acquisita was confirmed in six patients. Three patients with an inflammatory subepidermal autoimmune bullous disease mimicking bullous pemphigoid reacted with a 200 kDa protein on immunoblotting with dermal extract, as is characteristic of anti-p200 pemphigoid. One serum showed both roof and floor binding, and reacted with the BP180 antigen. LIMITATION: We could not perform serration pattern analysis in our patients. CONCLUSION: In this study, we report three cases of anti-p200 pemphigoid from India. These cases, though indistinguishable clinically from bullous pemphigoid, revealed a floor-binding pattern on indirect immunofluorescence using salt-split skin.

Efficacy and safety of erbium-doped yttrium aluminium garnet fractional resurfacing laser for treatment of facial acne scars.

BACKGROUND: Treatment of acne scars with ablative fractional laser resurfacing has given good improvement. But, data on Indian skin are limited. A study comparing qualitative, quantitative, and subjective assessments is also lacking. AIM: Our aim was to assess the improvement of facial acne scars with Erbium-doped Yttrium Aluminium Garnet (Er:YAG) 2940 nm fractional laser resurfacing and its adverse effects in 25 patients at a tertiary care teaching hospital. METHODS: All 25 patients received four treatment sessions with Er:YAG fractional laser at 1-month interval. The laser parameters were kept constant for each of the four sittings in all patients. Qualitative and quantitative assessments were done using Goodman and Barron grading. Subjective assessment in percentage of improvement was also documented 1 month after each session. Photographs were taken before each treatment session and 1 month after the final session. Two unbiased dermatologists performed independent clinical assessments by comparing the photographs. The kappa statistics was used to monitor the agreement between the dermatologists and patients. RESULTS: Most patients (96%) showed atleast fair improvement. Rolling and superficial box scars showed higher significant improvement when compared with ice pick and deep box scars. Patient's satisfaction of improvement was higher when compared to physician's observations. No serious adverse effects were noted with exacerbation of acne lesions forming the majority. CONCLUSION: Ablative fractional photothermolysis is both effective and safe treatment for atrophic acne scars in Indian skin.Precise evaluation of acne scar treatment can be done by taking consistent digital photographs.

Immunofluorescence antigen mapping for hereditary epidermolysis bullosa.

Epidermolysis bullosa (EB) is a group of inherited, mechanobullous disorders that are caused by mutations in the structural proteins in the epidermis or dermoepidermal junction. Characteristic clinical picture is the presence of blisters at trauma prone areas of the body, which develops at or soon after birth. Availability of specific monoclonal antibodies against the target proteins together with advances in the molecular genetics have led to the revision in the classification of EB. Now four major types of EB are recognized depending upon the level of blister and the location of target protein: EB simplex (epidermolytic), junctional EB (lucidolytic), dystrophic EB (dermolytic) and Kindler's syndrome (mixed cleavage plane). The laboratory tests not only help to confirm the diagnosis of EB but are also an important tool to classify (and subtype) EB. These include immunofluorescence antigen mapping (IFM), transmission electron microscopy (TEM) and mutation analysis. IFM is the most preferred method for final diagnosis of EB worldwide. It is relatively easy to perform and results can be obtained rapidly. This article describes the technicalities and significance of IFM in various types of EB.

Zosteriform cutaneous metastases: a case report and brief review of literature.

A 56-year-old woman presented with painful erythematous, papulo-nodular lesions on the left side of the trunk in a dermatomal distribution of two-weeks duration. She had earlier undergone surgery for breast carcinoma and was receiving palliative chemo-radiotherapy, when seen by us. A diagnosis of zosteriform cutaneous metastases was made and biopsy was done from the representative lesion which showed chords and sheets of malignant cells. Majority of these cases in the past have been misdiagnosed as herpes zoster and were treated with antiviral drugs. Metastatic diseases should be considered in the differential diagnosis of zosteriform rash in elderly.

Oro-facial aspects of leprosy: Report of two cases with literature review

Leprosy is a chronic infectious disease affecting primarily the skin, peripheral nerves, respiratory system andthe eyes. Leprosy induces various types of clinical presentation affecting the patient´s immune response. Cellmediatedimmunity is considered to be the crucial defence against the disease and the magnitude of this immunitydefines the extent of the disease. The article presents two case reports of manifestations of leprosy inthe oro-facial region, with a brief review of various other important oro-facial manifestations of leprosy. Thefirst report deals with granulomatous nodules in the palate while the second report presents bilateral facialpalsy in leprosy patients. Both the reports gain importance due to rare oral manifestation in a borderline leprosypatient in the first case, while the second case presents a rare bilateral Bell´s sign. The role of the dentalprofession and especially the Oral Medicine specialist is of great importance in early diagnosis of oral lesions (AU)

Multiple grade II deformities in a child: tragic effect of leprosy.

Stigma is almost synonymous with visible deformity and this is what makes leprosy a dreaded disease for the common man. Deformities in children are more distressing, due to the limitation of their physical, academic and social life. An 11-year-old female child was presented with trophic ulceration of right foot and triple nerve paralysis (i.e. total claw hand with wrist drop) of the left hand of 2 years duration. In addition, she had multiple hypopigmented hypoaesthetic patches on the extremities and buttocks. She was diagnosed as a case of borderline tuberculoid leprosy and was started on WHO MB MDT therapy. Leprosy in children is an indicator for disease prevalence in general population and occurrence of deformities points towards the delay in making the diagnosis and the stigma associated with the disease.
