RESUMO

Introduction: Tinea capitis (TC) is a common fungal infection of the scalp, especially in children. Trichoscopy is a noninvasive technique that allows rapid and magnified in vivo observation of the hair with the visualization of morphologic features that are often imperceptible to the naked eye. Aim: This study aimed to evaluate the usefulness of trichoscopy in clinical diagnosis and to study various clinico-morphological patterns of TC. Materials and Methods: This cross-sectional, observational study included 140 clinically diagnosed cases of TC seen during a period of 1 year (April 2021 to March 2022). All patients were evaluated using a dermoscope (DermLite DL4 Multispectral 3 Gen, San Juan Capistrano, CA, USA,10×). Results: The prevalence rate of TC in this study was 2.69 per thousand population. The most common clinical variant was gray patch followed by kerion and black dot, and the most common etiological agent was Trichophyton tonsurans. The characteristic trichoscopic features were as follows: comma hairs (80%), followed by corkscrew hairs (68.6%), bent hairs (54.2%), zigzag hairs (35.7%), and morse code-like hairs (15%). Other findings included scaling (89.2%), followed by black dot (67.1%), broken hairs (42.8%), and crusting and pustules (32.1% each). Comma and corkscrew-shaped hairs were most common in the black dot type, whereas zigzag, bent hairs, and morse code hairs were common in the gray patch type of TC. There was a significant association between trichoscopic findings and type of TC. Conclusion: Trichoscopy can be considered a novel tool for rapid diagnosis and selection of the appropriate therapy and in the monitoring of treatment efficacy in TC.

RESUMO

Background Despite acne being a common dermatological problem, there is a paucity of literature addressing the knowledge, attitude and practice about it. Aims/Objectives To find out what patients know about acne, its cause and treatment, as well as myths, misconceptions and attitude towards it. Methods A cross-sectional, descriptive questionnaire-based study on acne patients at Maharana Bhupal Hospital, RNT Medical College, Udaipur, Rajasthan, India. Results Most (84.8%) patients belonged to the age group of 16-25 years. The majority (63.9%) presented 12 months after the onset of acne. More than half had average knowledge, a positive attitude and good practices, related significantly to gender and education. Limitations A standardized questionnaire suitable for all dialects and regional languages would have yielded more uniform results. Conclusion Study revealed that acne patients still need to acquire accurate, adequate and easily accessible information to seek timely and appropriate treatment, and alleviate their psychological suffering.

RESUMO

As we were on the road to recovery from the coronavirus disease-19 (COVID-19) pandemic, the world is waking up to yet another potential adversary. Monkeypox (or human monkeypox) caused by monkeypox virus (an orthopox virus) is fast emerging in more than 80 countries worldwide, where it has never been historically reported. We in India, have already seen the advent of this outbreak since July 2022, with a progressive rise in number of cases being seen. Though the virus is not a novel virus; it is presenting with atypical manifestations as compared to our conventional knowledge of the disease. Through this document, the Indian Association of Dermatologists, Venereologists, and Leprologists Academy aims to sensitize dermatologists toward recognizing the clinical features and responding promptly, to contain the outbreak at the earliest. In view of the non-availability of specific antiviral drugs as well as vaccines; early detection, isolation, and prevention of spread form the mainstay of our approach towards the outbreak, which has been declared to be a "Public Health Emergency of International Concern" by the World Health Organization.

RESUMO

BACKGROUND: Stevens-Johnson syndrome and toxic epidermal necrolysis are severe, life-threatening mucocutaneous drug reactions with a high morbidity and mortality that require immediate medical care. Several immunomodulatory drugs are used for the treatment but evidence of their efficacy is limited. Cyclosporine has recently been found to have a promising role in SJS/TEN owing to its potent antiapoptotic activity. AIMS: This open label prospective study was conducted to determine the efficacy, safety, and tolerability of cyclosporine in patients with SJS/TEN. METHODS: This study was conducted at a tertiary care teaching hospital of South Rajasthan during a period of 4 years (August 2015 to July 2019). Data regarding clinical profile, causative drug(s), disease severity, associated comorbidities, treatment received, and outcome were recorded in a predesigned proforma. SCORTEN prognostic score was calculated for each patient at the time of admission. Cyclosporine was administered in a dose of 5 mg/kg body weight in two divided dosage until reepithelization. RESULTS: Out of 16 patients 10 were males and 6 were females. Mean age of patients was 30.62 ± 16.98 years (range: 7-63). Most of the patients, i.e., 8 out of 16 had TEN, 5 patients had SJS, and 3 patients had SJS/TEN overlap. Mean ± SD delay between onset and admission was 3.812 ± 1.377 days (range: 2-7). Among the suspected drugs, antiepileptics (43.7%) formed the major group. Mean duration of reepithelization was 10.5 ± 3.46 days (range: 7-15). Based on the SCORTEN, the expected mortality was 2.55 with mean predicted mortality rate of 16.43% with SD of 19.3. LIMITATIONS: 1) Sample size was small. 2) Placebo control trial could not be done due to the severity of the disease. CONCLUSION: We recommend cyclosporine (5 mg/kg/day) as the first line-specific immunomodulatory agent in SJS/TEN on account of its efficacy, safety, rapid reepithelization, decrease hospital stay, and reduced morbidity and mortality.

RESUMO

OBJECTIVE: The reduction of Coenzyme Q10 (CoQ10) levels following statin use has been linked to cause peripheral neuropathy. Hence, this study was planned to explore the effect of statin on the serum HMGCR (3-hydroxy-3-methyl-glutaryl-coenzyme A reductase), serum CoQ10 levels and nerve conduction and their correlation. PATIENTS AND METHODS: In an open labelled, cross-sectional, observational study, estimation of serum HMGCR and CoQ10 levels was performed in 50 atorvastatin/rosuvastatin users and 50 normal healthy volunteers (NHV). Statin users were also subjected to nerve conduction studies (NCS). RESULTS: Mean serum HMGCR level in NHV was higher (73.58 ± 7.64 ng/ml; p = 0.003) than that in statin users (49.11 ± 1.98 ng/ml). Similarly, mean serum CoQ10 levels was also lower (30.54 ± 2.03 ng/ml, p < 0.0001) in statin users than in NHV (49.43 ± 3.23 ng/ml). Amongst the 50 statin users, 29 had impaired NCS in sural, tibial and common peroneal nerve with lower mean serum CoQ10 levels (24.05 ± 1.96 ng/ml; p < 0.0001). Significant negative correlation was observed between onset time of action potential (AP) of the sural nerve and serum CoQ10 (r=-0.32) and HMGCR (r=-0.43) levels. There was significant positive correlation of conduction velocity of sural (r = 0.38) and tibial (r = 0.31) nerves with serum CoQ10 level. While conduction velocity in sural (r = 0.37) and common peroneal (r = 0.34) nerves positively correlated with serum HMGCR levels. The amplitude of the AP of the common peroneal nerve positively correlated with both serum CoQ10 (r = 0.52) and HMGCR (r = 0.46) levels. CONCLUSION: Statin users had lower serum CoQ10 and HMGCR levels associated with nerve conduction deficits suggesting a role of CoQ10 in the occurrence of the neurological adverse effects.

RESUMO

Background Evidence from the literature, highlights the increased risk of developing glucose intolerance and type 2 diabetes mellitus (T2DM) with statin therapy. In addition, few animal studies demonstrate that adipsin secreted from adipocytes plays a crucial role in insulin secretion and the development of T2DM. Methods To further explore the role of serum adipsin, in this prospective open label study, 55 newly diagnosed dyslipidemic patients were enrolled. Before starting statin therapy, liver function test (LFT), kidney function test (KFT), lipid profile, glycemic parameters [glycated hemoglobin A (HbA1c), fasting blood sugar (FBS), and postprandial blood sugar (PPBS)], serum insulin, and serum adipsin were estimated. Then these patients were prescribed statin (i.e. atorvastatin, rosuvastatin, or pitavastatin) and after 12 weeks of therapy, all the above investigations were repeated. Results After 12 weeks of statin therapy, the LFT and KFT values remained unchanged and lipid parameters showed significant improvement. But the glycemic parameters deranged significantly (p < 0.001), i.e. FBS, PPBS, and HbA1c increased by 12.49% (102.99 ± 20.76 mg/dL), 24.72% (147.71 ± 47.29 mg/dL), and 21.43% (6.38 ± 1.34%), respectively. On the other hand, the baseline adipsin (2.73 ± 1.99 ng/mL) and insulin (16.13 ± 12.50 mIU/L) levels reduced significantly (p < 0.0001) to 1.43 ±1.13 ng/mL and 6.91 ± 5.93 mIU/L, respectively. The reduction in serum adipsin also showed a positive correlation with reduction in serum insulin (r = 0.85; p < 0.0001). None of the patients experienced any significant adverse effect or reaction leading to discontinuation of therapy. Conclusions There might be an association between reduction in adipsin and development of glucose intolerance by statin therapy.

RESUMO

BACKGROUND: Vitiligo is an acquired, idiopathic, and common depigmentation disorder. The values of various epidemiologic parameters are often doubtful due to the methodological weaknesses of the studies. AIMS: To elicit the magnitude of various epidemiological parameters and important correlates of vitiligo. MATERIALS AND METHODS: Every vitiligo patient attending the outpatient department of medical colleges spread over most of the Indian states were examined over a period of 1 year. Various epidemiological and clinical variables were examined and compared with age and sex-matched controls (registered in the Clinical Trial Registry of India CTRI/2017/06/008854). RESULTS: A total of 4,43,275 patients were assessed in 30 medical colleges from 21 Indian states. Institutional prevalence of vitiligo was 0.89% (0.86% in males and 0.93% in females, P < 0.001). The mean age at presentation and mean age at onset were 30.12 ± 17.97 years and 25.14 ± 7.48 years, respectively. Head-neck was the most common primary site (n = 1648, 41.6%) and most commonly affected site (n = 2186, 55.17%). Most cases had nonsegmental vitiligo (n = 2690, 67.89%). The disease started before 20 years of age in more than 46% of cases. About 77% of all cases had signs of instability during the last 1 year. The family history, consanguinity, hypothyroid disorders, and depressed mood were significantly (P < 0.001) higher among the cases. First, second, and third-degree family members were affected in 269 (60.04%), 111 (24.78%), and 68 (15.18%) cases, respectively. Work-related exposure to chemicals was significantly higher among cases (P < 0.008). Obesity was less common among vitiligo cases [P < 0.001, odds ratio (OR) 0.78, 95% confidence interval (CI): 0.71-0.86]. CONCLUSION: This is one of the largest studies done on vitiligo in India. The prevalence of vitiligo was found to be 0.89% among hospital attendees. Prevalence of vitiligo was higher among females than in males and prevalence of family history, consanguinity, hypothyroid disorders were higher in vitiligo than among controls.

RESUMO

Two adult patients from a village of district Bhilwara, Rajasthan, consulted Skin Department of R. N. T. Medical College and Hospital, Udaipur, with complaints of thickening of the palms and soles and pigmentation of skin with a nonhealing ulcer on the palm. They also had complaints of loss of appetite, abdominal pain, nausea, vomiting, and loose motion. On examination, there were multiple 2-3 mm, keratotic papules on the palms, and soles on the background of diffuse keratoderma. Two irregular nonhealing ulcers were present on the hands which on excisional biopsy revealed squamous cell carcinoma. A generalized mottled pigmentation was present over the trunk and proximal parts of extremities. The clinical presentation was suggestive of arsenicosis. There was history of similar ailment in some of the fellow villagers as well. With the help of health authorities, a survey was conducted in the village and it was found that eight more villagers were suffering from similar kind of illness. The common source of arsenic was explored and found to be increased in drinking water that was taken out through hand pump. The level of arsenic in drinking water was significantly above the WHO safe limit for arsenic.

RESUMO

BACKGROUND: Cutaneous adverse drug reactions (CADRs) are probably the most frequent of all manifestations of drug sensitivity. As a considerable number of new drugs are periodically introduced into the market, the incidence of CADR is likely to increase. The pattern of CADR and the causative drugs is likely to change accordingly. There is no uniformly accepted and reliable method of objectively assessing the causal link between drug and adverse reaction. AIM: To study the clinical patterns and causative drugs and compare causality assessment [World Health Organization (WHO) and Naranjo algorithm] of CADR among patients attending the dermatology department. MATERIALS AND METHODS: This is a cross-sectional hospital-based study in which all patients with suspected CADR attending the dermatology department of a tertiary care center over a 9-month period were evaluated using the causality assessment criteria recommended by the WHO-Uppsala Monitoring Centre (UMC) and Naranjo scale. The severity of the reaction was assessed using Adverse Drug Reaction Severity Assessment Scale (modified Hartwig and Siegel scale). RESULTS: A total of 200 consecutive patients with CADR were evaluated. The causality assessment for a drug as per WHO scale yielded 63 (31.5%) cases as certain, 12 (6%) as probable, and 125 (62.5%) as possible, whereas Naranjo scale showed 26 (13%) cases to be definite, 138 (69%) as probable, and 36 (18%) as possible. There was poor agreement between the two scales. Fixed drug eruption was the most common pattern of CADR (82.41%). The average number of drugs received by patients was 2.09. The most common suspected drug group was antimicrobials (n = 170; 40.5%), followed by nonsteroidal anti-inflammatory drugs (n = 148; 35.3%) and antiretroviral drugs (n = 41; 9.7%). Fixed drug eruption was most commonly caused by paracetamol. Antiepileptics and antimicrobials were the most common suspects among severe cutaneous adverse reactions. LIMITATIONS: Multiple concomitant drug usage by patients and inability to provoke all patients/measure drug levels in blood resulted in higher number of drugs with causal association as probable/possible. CONCLUSION: WHO-UMC scale was found to be easier to apply and evaluate, with greater practical utility. Poor agreement between the two commonly used scales emphasizes the need for a consistent and uniform causality assessment tool.

RESUMO

Any drug can cause any rash! Cutaneous adverse drug reactions (CADRs) are great mimickers and can be included in the differential diagnosis of any inflammatory dermatoses. Several drugs can cause rash of similar morphology and the same drug can cause rash of different morphology. While some common and specific drug reaction patterns are recognized easily by the clinicians, many a times unusual and interesting patterns can be induced by drug(s), thus leading to erroneous diagnosis and mistreatment. This review aims to familiarize clinicians with some rare, yet interesting patterns of CADR.
