Role of Patch Testing in Facial Contact Dermatitis: A Cross-Sectional Study from Central India.

Background: Facial contact dermatitis is an emerging skin disorder due to the use of a large array of materials over the face. It leads to psychological distress in patients, impacting their quality of life. Most of the allergens applied over the face vary as per cosmetic or herbal products' availability, usage, or religious practices. Identifying and discontinuing the implicated allergens will lead to a better prognosis and reduced morbidity in clinical practice. Objectives: To determine the frequency of different allergens responsible for causing facial contact dermatitis, in an urban part of central India, using patch test with the help of Indian standard and cosmetic series. Materials and Methods: All suspected patients (>18 years) of facial contact dermatitis visiting the outpatient department of dermatology were patch tested with both Indian standard and cosmetic series. Results: Out of 38/58 patch-test-positive patients, 71.06% were females, and 28.94% were males. Most patch-test-positive females were housewives. The most common allergens implicated were thiomersal (17.24%), followed by fragrance mix (15.51%), and paraphenylene diamine (12.06%). Conclusion: In our study, forehead and malar areas were most commonly involved indicating fairness creams and perfumes as the important contributors to facial contact dermatitis. Antigen batteries need to be updated with changing social and cultural trends, as many with a consistent history of aggravation with some products tested negative in patch tests.

Penicillamine-induced Stevens Johnson Syndrome-toxic Epidermal Necrolysis (SJS-TEN) Overlap in an HIV-infected Patient with Wilson's Disease and Hepatitis B.

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.

Morphological Diagnosis of Blastomycosis Clinically Presenting as Mycetoma in a Young Immunocompetent Indian Patient; A Diagnostic Dilemma.

Primary cutaneous blastomycosis is very rare in non-endemic regions like India. Only few cases have been reported from India. Herein, we are reporting a rare case of chronic cutaneous blastomycosis in a young immunocompetent male presenting as mycetoma with multiple discharging sinuses in the anterior abdominal wall with no significant travel history.

Clinico-Demographic Profiles of Herpes Zoster Cases in Patients With and Without COVID-19 Infection During the Pandemic: A Retrospective Analysis of 32 Cases.

BACKGROUND: Coronavirus disease 2019 (COVID-19) has multiple impacts on the human body. The immunological effect is one of the prominent ones, which is thought to be fundamental in many physical manifestations and disease severity. Herpes zoster (HZ) reactivation has been well-linked to immunity; immunocompromised states predispose a person to HZ. Studies have raised concerns about HZ incidences in COVID-19 patients; however, the clinical characteristics of the HZ cases among patients with and without COVID-19 are another area to be explored. METHODS: In this retrospective analysis, we compared the clinical and demographic characteristics of HZ cases presented to our outpatient department immediately before and during the early second wave of the COVID-19 pandemic (September 2020 to April 2021) in India. The cases were divided into two groups based on the history of COVID-19 infections. The clinico-demographic characteristics were then compared using an unpaired t-test, Fisher's exact test, and analysis of variance as applicable using InStat software; a two-sided p-value <0.05 was considered significant. RESULTS: During the period, 32 cases (17 HZ cases with a history of COVID-19; 15 HZ cases without) were detected. The age and gender distribution were indifferent statistically. Our analysis showed that multi-dermatomal and disseminated involvements were significantly higher in HZ cases having a history of COVID-19. CONCLUSION: The present retrospective analysis of 32 cases indicates that persons who suffered from COVID-19 and presented with HZ were likely to have a higher chance of multi-dermatomal and disseminated involvement. While our analysis cannot establish a true association between COVID-19 infection and HZ reactivation, which will require a large-scale study, clinicians might get a clue of the possible progression of the extent of HZ manifestations from our findings.

Role of Autoerythrocyte Sensitization Test in the Diagnosis of Recurrent Spontaneous Bruising.

Introduction: Psychogenic purpura, also known as autoerythrocyte sensitization syndrome, is a rare condition which is characterized by spontaneous development of painful purpura, or ecchymoses. Skin lesions are usually preceded by stress and emotional trauma. It is usually a diagnosis of exclusion after ruling out history of trauma, drug intake and other bleeding disorders. Autoerythrocyte sensitization test (AEST) and a psychiatric evaluation helps in the diagnosis and treatment. Objective: To demonstrate the importance of AEST in diagnosing the patient of Gardner Diamond syndrome. Materials and Methods: Five suspected cases of autoerythrocyte sensitization syndrome underwent AEST after ruling out other causes of bleeding. Results: Four out of five patients were positive for AEST while one patient was negative. Psychiatric complaints were present in three patients. One patient was lost to follow up. Rest all patients responded well to vitamin C supplementation. Conclusion: Autoerythrocyte sensitization syndrome is a rare disorder and is a diagnosis of exclusion, so a thorough workup of the patient to rule out common causes of bruising is essential. A high index of suspicion on the clinician's part and a simple OPD-based AEST may help in the diagnosis. Psychiatric consultation is important to find out the stress factor and timely management.

Linezolid: a safer and effective substitute to aminoglycoside in the treatment of actinomycetoma by Nocardia species.

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.

An Analysis of Interns' Feedback after Dermatology Posting.

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.

Palatal perforation in a patient with borderline lepromatous leprosy: leprosy still not eradicated.

Leprosy was eliminated globally in 2000, but it continues to be endemic in developing countries like India, Brazil and Indonesia, with a prevalence of 0.57/10 000 persons in India (2020). At the end of the year 2020, the prevalence was 129 389, and oral manifestation of the leprosy is luncommon. We hereby report a case of a female patient in her late 30s who presented with palatal perforation. Following a thorough history taking and full body clinical examination, we arrived at a diagnosis of leprosy, and prompt treatment was initiated. Knowledge of cases like this becomes important as the oral lesion is said to form an essential source of leprosy dissemination in the community, and awareness about them becomes crucial, demanding immediate attention.

Multifocal cutaneous tuberculosis coexisting with pulmonary tuberculosis.

Tuberculosis (TB) is caused by Mycobacterium tuberculosis and it can affect multiple organ systems. Cutaneous TB, a less common type of extrapulmonary TB can coexist with TB of other organs. Here, we describe a case of multifocal cutaneous TB suggestive of two different morphological types with concomitant miliary pulmonary TB.

Rare Co-Existent Dermatitis Herpetiformis and Psoriasis in a Child: A Causal Relationship?

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.

Relapse of pemphigus foliaceus initiating at the site of irradiation in an elderly male with laryngeal carcinoma: Illustrating the concept of immunocompromised cutaneous district.

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.

Grade 2 disability among leprosy patients: A pilot study from an endemic area of Central India.

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.

Coronavirus disease 2019 vaccination in patients with psoriasis: A position statement from India by SIG psoriasis (IADVL Academy).

Coronavirus disease 2019 (COVID-19) pandemic has affected every sphere of life including management of psoriasis. The availability of COVID-19 vaccines has given rise to hope and at the same time some apprehensions as well. With the general population becoming eligible for vaccination, there is some confusion, on the eligibility of patients with different medical conditions and patients on immunosuppressive or immunomodulating medications for COVID-19 vaccination. Dermatologists treating psoriasis patients frequently face questions from them, whether they can undergo coronavirus disease 2019 vaccination. A PUBMED search was performed using the following strategy: 'COVID-19' AND 'Vaccine' AND 'Psoriasis'. We also performed a PUBMED search using the following strategy: 'SARS-CoV-2' AND 'Vaccine' AND 'Psoriasis'. All articles irrespective of language and publication date were included to arrive at this position statement. This position statement deals with the safety, eligibility and modifications of treatment, if needed among psoriasis patients with regards to the coronavirus disease 2019 vaccines currently available in India.
