RESUMO
Resistance to antileprosy drugs is one of the main contributors for the persistence of leprosy in the present era. In the absence of universal antimicrobial resistance (AMR) surveillance through the national program, the indications for resistance testing remain a important dilemma to clinicians. WHO recommendations mainly focus on clinical relapse, which could be picked up late with continued transmission and repeated leprosy reactions in the patient. We report here a series of eighteen leprosy cases who were tested for AMR in view of the positive morphological index after completion of multidrug therapy, chronic Erythema nodosum leprosum, and clinical relapse.
RESUMO
INTRODUCTION: Stevens-Johnson syndrome (SJS) and Toxic epidermal necrolysis (TEN) are severe adverse drug reactions characterized by widespread blistering and mucositis. Wilson's disease is a rare, autosomal recessive disorder that results in excessive copper accumulation in the body, where penicillamine is an effective treatment option for copper chelation. Penicillamineinduced SJS-TEN is a rare but potentially fatal adverse effect. There is increased susceptibility to SJS/TEN in HIV infection due to immunosuppression and chronic liver disease due to impaired hepatic function. OBJECTIVE: To diagnose and manage the occurrence of the rare severe adverse cutaneous drug reactions in the backdrop of immunosuppression and chronic liver disease. CASE REPORT: We are reporting penicillamine-induced SJS-TEN overlap in a 30-year-old male with Wilson's disease, HIV and Hepatitis B who was treated with intravenous immunoglobulins. The patient later developed neurotrophic ulcer in the right cornea as a delayed sequela. CONCLUSION: Our case report emphasizes that there is an increased predisposition to SJS/TEN in immunocompromised and chronic liver disease patients. Physicians should be well aware of the potential danger of SJS/TEN in this subset of patients, even while prescribing a relatively safer drug.

Actinomycetoma is chronic, suppurative, granulomatous infection caused by bacteria and requires prolonged antibiotic therapy preferrably in combinations. Nephrotoxicity is a common side effect of aminoglycosides used in the management of actinomycetoma. We report here two cases of actinomycetoma due to Nocardia species who received linezolid as a substitute to aminoglycosides after developing nephrotoxicity.

BACKGROUND: There have been increasing reported cases of new-onset or aggravation of pre-existing dermatoses after the implementation of COVID-19 vaccination. CASE PRESENTATION: An elderly male was presented with multiple annular scaly plaques all over the body two weeks following administration of the first dose of Oxford-AstraZeneca COVID-19 vaccine. The lesions further aggravated after taking the second dose of the vaccine. The clinical and histopathology features were suggestive of annular plaque psoriasis. CONCLUSION: We report this first case of de novo plaque psoriasis following the Oxford- AstraZeneca COVID-19 vaccine, and it signifies a potential side effect of autoimmune reactivation after COVID vaccination.

BACKGROUND: Methotrexate is an antimetabolite anticancer drug frequently used in the treatment of extensive chronic plaque psoriasis. Psoriasis patients on treatment with immunosuppressants have an increased risk of developing malignancies. OBJECTIVE: To present a rare case of Oral Squamous Cell Carcinoma (OSCC) in a psoriasis patient postacute methotrexate toxicity. CASE REPORT: A 47-year-old female, a known case of chronic plaque psoriasis for which she was on 15 mg/ week methotrexate therapy and accidentally consumed 15 mg for 7 consecutive days. She was successfully treated for methotrexate toxicity and 45 days later she presented with exophytic growth on the tongue. Histopathology confirmed the diagnosis of squamous cell carcinoma and the patient underwent surgical resection. CONCLUSION: There could be a causal association between psoriasis and OSCC in the setting of acute methotrexate toxicity, as in the present case.

Blastomycosis-like pyoderma (BLP) is an uncommon tissue response possibly to bacterial infection that presents as vegetative skin lesions usually in immunocompromised patients. Staphylococcus aureus is the most frequent pathogen implicated in BLP. Here, we report the case of a 32-year-old man who had ulcerative vegetating lesions on extremities for 3 months over preexisting recalcitrant tinea lesions. The patient was hypertensive with a history of chronic graft rejection after renal transplantation 8 months earlier and was on long-term immunosuppressants. Investigations revealed anemia, mild hyperglycemia, and elevated serum creatinine. Histopathology showed suppurative and fibrosing perifolliculitis with moderate pseudocarcinomatous hyperplasia and the culture of biopsy specimen demonstrated growth of Escherichia coli and Citrobacter koseri. The diagnosis of BLP overlying dermatophytoses was made. The skin lesions improved completely with parenteral antibiotics. Local immune dysregulation by dermatophytoses along with iatrogenic immunosuppression may have favored this rare pyoderma.

Non-segmental vitiligo (NSV) is an autoimmune disorder due to the destruction of melanocytes, where cytokines like interleukin 17 (IL-17) and biomolecules like vitamin D play a theoretical role in pathogenesis. Previous studies in this regard yielded inconsistent results. This study aimed to compare the serum levels of IL-17 and vitamin D between NSV patients and healthy controls and to know the association of these biomarkers with disease activity and extent. This was a case-control study including adult patients with NSV and age and gender-matched healthy controls. Cases and controls with conditions likely to alter the serum levels of IL-17 and vitamin D were excluded. Serum levels of IL-17 were estimated by ELISA and vitamin D levels by chemiluminescence assay. 42 adult patients of NSV and 42 age and sex-matched healthy controls were recruited over a period of eighteen months. The mean value of serum vitamin D levels in the control group was 19.053 ± 5.340 ng/ml, whereas in the case group, it was 17.336 ± 6.931 ng/ml (P > 0.05). The mean value of serum IL-17 levels in the control group was 199.824 ± 51.244 pg/ml and 213.566 ± 69.018 pg/ml in the case group (P > 0.05). These molecules did not show any association with the disease activity and extent. In contrast to the previous studies, we could not establish the role of IL-17 in the pathogenesis of vitiligo. Furthermore, we could not find any association between vitamin D and vitiligo in our study, even though there is an inconsistent association between the two in the available literature.
RESUMO
New pathways of host defence have emerged in leprosy, such as T helper (Th) -17, Th-9, T regulatory cells, and other factors like transforming growth factor-beta, etc. Interleukin (IL) 17 produced by Th17 cells has been found to be elevated in lepra reaction, especially type 2 lepra reaction (T2R). Role of IL-9 has not been studied widely in leprosy reactions so far. The study aimed to compare serum levels of IL-17 and IL-9 in leprosy patients with and without lepra reaction. This was a cross-sectional analytical study including untreated adult leprosy patients with and without lepra reaction. A total of 65 patients were included in the study with 30 leprosy patients without reaction and 35 with lepra reaction. Serum levels of IL-17 and IL-9 were measured in these patients using direct enzyme-linked immunosorbent assay and were compared. Borderline tuberculoid (BT) leprosy with type 1 and Lepromatous (LL) leprosy with T2R patients showed significantly higher levels of IL-17 than BT and LL leprosy patients without lepra reaction, respectively. LL patients with T2R showed significantly lower levels of IL-9 than lepromatous cases without reaction. IL-9 levels were higher in BT patients with T1R as compared to BT patients without reaction but the difference was not significant. We found evidence in support of role of IL-17 in the pathogenesis of T2R, which might serve as useful serum markers for the same. IL-17 might have a role in BT leprosy with T1R. IL-9 seems to have a protective role in T2R as opposed to IL-17, working in synergism with Th1 cytokines.
RESUMO
Background: Dermatology knowledge among fresh medical graduates is poor in India as undergraduate medical curriculum and Internship training lack adequate focus on this subject. This contributes to the inappropriate management of Dermatology patients by the medical graduates. Objective: To analyse the expectations, motivations and experience of interns during their dermatology posting. Materials and Methods: This was a retrospective record review of questionnaire-based anonymous validated feedback forms submitted by interns posted in a dermatology department of a tertiary care institute. The feedback form contained nine multiple choice questions some of which allowed multiple responses. Results: A total of 63 completed forms were analysed. The common expectations before the posting were, to learn the management of basic dermatological problems (98.4%), to take an informed decision regarding post-graduation in dermatology (53.9%) and hope that the posting will be useful for the postgraduate entrance test (50.7%). After the posting, 69.87% of them felt that their expectations were fulfilled. After the posting, 84.1% of the interns felt that they would have liked to study dermatology as a separate undergraduate subject with a summative assessment at the end. Limitations: The sample size was less and the feedback form contained limited questions. Conclusion: The majority of the interns were satisfied after dermatology posting. Increased exposure of interns to dermatology inpatients and side laboratory procedures will further enrich their clinical experience. The inclusion of dermatology as a separate subject with examination in the undergraduate curriculum was a felt need.
RESUMO
Dermatitis herpetiformis (DH) is an auto-inflammatory skin disease that is linked to gluten sensitivity and is related to celiac disease (CD). Psoriasis is an inflammatory skin disorder found to have an association with the celiac disease, according to various genetic and epidemiological studies. We report a 12-year-girl who presented with multiple tense blisters along with red raised, scaly and itchy lesions over her body. She was a known case of psoriasis and was diagnosed as dermatitis herpetiformis in an immunofluorescence study. In this case report, we want to highlight the fact that the co-existence of dermatitis herpetiformis and psoriasis could be more than a mere coincidence. In our patient's previously uncontrolled psoriasis and dermatitis herpetiformis both improved after a gluten-free diet along with systemic therapy.
RESUMO
Radiotherapy-induced or -aggravated pemphigus is not a common occurrence with only a few cases reported so far. The radiation disrupts the local immune regulation and alters the antigenicity of keratinocytes, but the exact etiology is not clear. We report a case of an elderly man operated for laryngeal carcinoma who presented with recurrence of pemphigus foliaceus lesions starting at the irradiation site. The appearance of vesiculobullous lesions at the site of irradiation should be evaluated thoroughly to rule out immunobullous diseases.

INTRODUCTION: Periorbital melanosis (POM) has a significant impact on quality of life. There is a dearth of literature regarding POM, especially in Asian population. Accurate classification of POM is contributory to the choice of therapy. The aim of this study was to assess the role of dermoscopy in etiologic classification of POM. METHODS: Two hundred and fifty adult patients (age > 18 years) of POM were enrolled over a period of 2 years. POM was classified clinically and re-evaluated based on their dermoscopic findings (pattern of pigmentary and vascular involvement, surface changes). RESULTS: Pigmented, vascular, structural, and mixed types of POM represented 6.4%, 4.8%, 0.4%, and 88.4%, respectively. Dermoscopy was found to be statistically more accurate in classifying pigmentary and vascular types of POM as compared to clinical examination with the naked eyes (p- value <0.05). Patchy or post-inflammatory pigmentation was the most common pigmentary pattern on dermoscopy (53.8%) followed by pseudoreticular (37.1%) and mixed pattern (9.1%). 80.4% patients had vascular involvement of which the most common vascular pattern was telangiectasia (58.8%). Wrinkling or increased skin laxity as a cause of shadow effect was found in 52% patients. Diffuse erythema and scaling suggestive of subtle inflammation was detected in 47.6% patients on dermoscopy. CONCLUSION: Dermoscopy as a diagnostic modality is more accurate in detecting pigmentary and vascular causes of POM and subtle signs of active inflammation in the form of erythema and scaling which is difficult to detect clinically. The major limitations of this study were lack of correlation of dermoscopic findings with the histological findings and the absence of any control group for comparison.

Background and Aim: Deformities and disabilities in leprosy lead to significant morbidity to the individual and financial burden to the family. As the prevalence of leprosy is higher in central India, this study was conducted to know the burden of deformity and disability among leprosy patients in central India and the factors associated with it. Materials and methods: This was a hospital-based, cross-sectional study, conducted on 50 new or on treatment or released from treatment leprosy patients, attending the Dermatology OPD of a tertiary care institute in Central India. Disability was graded as per the WHO criteria for disability grading of hands and feet. Results: Grade 2 disability was found among 32% of the patients with leprosy, whereas a total of 60% of our patients had either grade 1 or grade 2 disabilities. Trophic ulcer was found among 20% and claw hand among 14% of leprosy patients. We found significant associations of lepromatous leprosy with trophic ulcer (p = 0.004) and grade 2 disability (p = 0.012). All patients with claw hands and 80% of the patients with trophic ulcers presented to the healthcare facility at least 6 months after the onset of symptoms. Conclusions: We found very high rates of disability and deformity among leprosy patients indicating possible huge burden of morbidity among leprosy patients in central India. The significant association of lepromatous leprosy with trophic ulcer and grade 2 disability indicated delayed presentation and diagnosis of lepromatous leprosy patients. Our results underlined the need for large scale community-based studies on disability and deformity among leprosy patients in Central India. These results also call for better training of primary level healthcare workers for early detection and management of deformities and disabilities as well as better patient education for leprosy patients regarding hand and foot care.

INTRODUCTION: This study investigated the perspectives of medical students on the factors influencing empathy development during their undergraduate training. METHODOLOGY: A descriptive phenomenological approach was used to generate illustrations of empathy development and decline that had educational significance and applicability. Individual online semi-structured interviews were conducted to elicit experiential details from twelve final-year medical students. The interview recordings were transcribed verbatim, and data were analysed employing Braun and Clarke's thematic analysis method. RESULTS: The self-reported empathic behavior of medical students seemed to have improved with time in medical school. Students attributed their empathy development to real patient encounters, positive role-modelling by teachers, and attainment of confidence and personal maturity. They identified exams, academic overload, time constraints, personal stresses, negative role models, unconducive learning environments, and lack of formal empathy training as barriers to empathy development. CONCLUSION: Medical institutes should identify and address the barriers to empathy development and encourage the holistic development of medical students. Furthermore, medical educators should model their behavior accurately for their increasing roles and responsibilities and support the students in their empathic expressions with patients.
RESUMO
PURPOSE: Since ancient era leprosy is existing across the world. India, Indonesia and Brazil still harbour major proportion of global cases. Child leprosy and Grade II disability indicate delayed diagnosis and persistence of transmission in community. So, this study was conducted with aim to evaluate the diagnostic efficacy of PCR in comparison to SSS (Slit Skin Smear) microscopy for detection of leprosy in early stages in both cases and carriers (contacts). METHODS: A cross sectional observational study was conducted on 100 subjects including 50 clinically diagnosed new cases of leprosy and their 50 contacts. Each group was subjected to SSS (Slit Skin Smear) microscopy and PCR using RLEP gene as target. RESULTS: The overall male: female ratio was 2.44. The Slit Skin smear (SSS) microscopy positivity was 34% (nâ¯=â¯17/50) among cases while it was 0% (nâ¯=â¯0/50) among contacts. The overall positivity for PCR was 42% (nâ¯=â¯42/100) being 66% (nâ¯=â¯33/50) in cases and 18% (nâ¯=â¯9/50) in contacts. About 30% (nâ¯=â¯25/83) of all the microscopically negative subjects were found to be positive by PCR. CONCLUSIONS: PCR was found to be a better diagnostic tool both among cases and their contacts. It should be used for screening contacts for early diagnosis and treatment and thus preventing transmission in community. KEY MESSAGE: To diagnose case and contacts of leprosy in early stages even in very low bacterial density using PCR.

CONTEXT: Feedback processes are intricate, generally misunderstood, hard to execute efficiently, and often fail in their goals to influence students learning. Research highlights that students usually do not value the benefits of feedback. This paper reviews the literature on the definition, purpose, and models of feedback; and on exploring why some students do not value feedback, what factors are influencing the effectiveness of feedback, and how to improve the efficacy of feedback. EVIDENCE ACQUISITION: The relevant articles were searched through 'Google Scholar,' 'CINAHIL' and 'PubMed' using the key terms- "Student feedback," "Frameworks of feedback," "Barriers to effective feedback," and "Students' perspectives on feedback." The search criteria included: review and original research articles in the English language published in high-impact journals in the past ten years. RESULTS: The results of different studies have illuminated diverse factors demanding the attention of educators to the effectiveness of feedback. Personal, relational, procedural, and environmental factors seem to affect the utility of feedback. To be effective, feedback should be actionable, non-judgmental, descriptive and specific, based on observable behavior, and should be given at a mutually agreeable time and place. CONCLUSION: The efficacy of feedback can be enhanced by creating students' feedback literacy, addressing students' perceptions and expectations, encouraging productive educational alliances, improving procedural elements of feedback, and environmental conditions.
