RESUMEN
Viral vector vaccines (Covishield) and inactivated vaccines (Covaxin) are now being administered worldwide to reduce the impact of life-threatening corona virus disease 19 (COVID-19). Various cutaneous adverse drug reactions (CADRs) have been reported following COVID-19 vaccination. Here, we are reporting series of CADRs following COVID-19 vaccination. Among 18 CADRs, 4 each were of acute urticaria and pityriasis rosea, 2 each of leukocytoclastic vasculitis and herpes zoster, 3 exacerbation of psoriasis, and 1 each of exacerbation of eczema, reactivation of herpes simplex virus 1 infection, and COVID arm. However, in 1 case there was remission of psoriasis. These CADRs occurred between 6 hours and 20 days after vaccination and were mild to moderate in severity. Only 1 needed hospitalization. Of the 18 CADRs, 10 developed after first dose and 8 after second dose. Causality assessment was done using World Health Organization causality assessment classification. Mass COVID-19 vaccination program is in progress worldwide. Many CADRs like COVID arm, urticaria, pityriasis rosea, leukocytoclastic vasculitis, herpes zoster etc., have been reported following vaccination. In our series only 1 developed cutaneous adverse drug reaction (CADR) to Covaxin. It was Covishield that was administered during the vaccination drive; hence, more cases were seen to that vaccine. Most of the CADRs were mild to moderate in intensity. Awareness of these adverse effects enables the healthcare professionals to be better equipped to recognize and manage them correctly.
RESUMEN
BACKGROUND: Lesions on the external genitalia could be venereal or non-venereal. Non-venereal genital dermatoses are common and may cause considerable anxiety to patients, particularly if noticed after sexual intercourse. However, this aspect has not been studied much till now. OBJECTIVES: Our study proposes to describe the profile of non-venereal genital dermatoses and determine their impact on quality of life both social and sexual, using the dermatology life quality index questionnaire. METHODS: We recruited patients aged 18 years and above, who were diagnosed to have non-venereal genital dermatoses during the study period. A detailed history was obtained and clinical examination done with relevant investigations when necessary. The dermatology life quality index was assessed and graded in all patients using Finlay dermatology life quality index questionnaire. RESULTS: A total of 293 patients with non-venereal genital dermatoses were seen and 25 different dermatoses were observed. Men 242(82.6%) outnumbered women. The commonest age group affected was 31-50 years 144(50%). Chronic inflammatory dermatoses 135(41.6%) constituted the majority of cases. Scrotal dermatitis 46(15.7%), lichen simplex chronicus 37(12.6%), vitiligo 31(10.6%) were seen most frequently. In the study group, 111(37.9%) patients had moderate and 133(45.4%) had large impact on the quality of life. Erectile dysfunction was seen in 48(19.8%) men and 9(3.7%) had premature ejaculation. A significant effect on dermatology life quality index was found with increasing age (P = 0.007), positive marital status (P = 0.006), history of unprotected sex (P < 0.001), history of recurrences (P = 0.002) and venereophobia. (P = 0.008). LIMITATIONS: The number of women in the study group was less compared to men and we could not ascertain the type of sexual dysfunction in them. CONCLUSION: Non-venereal genital dermatoses are common, more so among men. They have a significant impact on the quality of life of the individual. Recognizing and addressing this problem will help in managing these patients effectively.

BACKGROUND: Studies on mice and aging human hair follicles provide compelling evidence that graying of hair results from premature differentiation of melanocyte stem cells in the niche/bulge. OBJECTIVE: The aim of this study was to analyze whether differentiation of melanocyte stem cells is responsible for premature graying of hair (PGH). METHODS: Twenty-five patients with PGH (n = 25) attending the dermatology department were recruited. Five unpigmented and 5 pigmented hairs were obtained per patient by separating individual follicles after 1 mm punch biopsies. The hairs were dissected at a distance of 2 mm from the bulb to separate the stem cells (upper segment - US) from the melanocytes (lower segment - LS). RNA was extracted from hair follicle US and LS, and expression of GP100, tyrosinase (TYR), and tyrosinase-related protein-1 (TYRP1) genes was quantified using Qiagen one-step RT-PCR kit. RESULTS: We found melanogenesis gene expression in both temporary (US) and permanent (LS) segments of unpigmented and pigmented hair follicles. When compared between the US and LS of white hair, the expression of TYR and GP100 was much higher in US than LS, suggestive of melanogenesis in the bulge. Similarly, when compared between white and black US, the expression of all 3 genes was higher in white US than black US, although not statistically significant. LIMITATIONS: Low samples size and lack of data pertaining to the expression of genes at protein level are the limitations of current study. CONCLUSION: Even though this pilot study data yielded key information about the expression of GP100, TYR, and TYRP-1 at the mRNA level, further studies quantifying the expression of these genes at protein level are needed to provide additional clues to further address the results in detail.

Acquired ungual fibrokeratomas are uncommon fibrous tissue tumors that are located in the ungual area. They usually presents as asymptomatic, solitary, smooth, dome-shaped, or fingerlike, flesh-colored papules accompanying nail deformities, including a longitudinal groove and trachyonychia. Acquired periungual fibrokeratoma is considered a topographical variant of acquired digital fibrokeratoma; it has a unique "garlic clove" shape. A traumatic origin has been suggested, as acquired ungual fibrokeratomas occur most frequently on the fingers and toes. Herein, we report a case of a 29-year-old man with growth over left little finger, who was treated with surgical excision of the tissue. Histopathological examination confirmed ungual fibrokeratoma. It is a rare variant of digital fibrokeratoma, and so far the first ungual fibrokeratoma to appear de novo on little finger to the best of our knowledge.
RESUMEN
Segmental zoster paresis is characterized by focal motor weakness affecting the myotome corresponding to the dermatomal distribution of the rash. Clinically, it presents as pseudohernia when it involves abdominal wall muscles. We report three cases of segmental zoster paresis presenting as pseudohernia of abdominal wall. All patients developed asymptomatic bulge in anterolateral side of abdomen between 10 and 15 days after appearance of vesicles. All patients developed post-herpetic neuralgia. One patient developed pseudo-obstruction of colon due to visceral involvement. Segmental zoster paresis of lower thoracic spinal segment often goes unnoticed due to its asymptomatic nature.
RESUMEN
Cefpodoxime is a common antibiotic with a favorable side effect profile. Drug Rash with Eosinophilia and Systemic Symptoms (DRESS) syndrome has been described with several cephalosporins but not cefpodoxime. We report the probable first case of cefpodoxime-induced DRESS syndrome in a 52-year-old female patient. In our case, the patient presented with symptoms of DRESS syndrome 16 days after initiation of cefpodoxime. This case highlights the necessity of consideration of an iatrogenic reason for presenting signs and symptoms at all times. Reinforcing the importance of taking a thorough drug history and considering drug reactions even if onset of symptoms are delayed.

BACKGROUND: Cosmetovigilance is a term used for the activities related to the collection, evaluation, and monitoring of reporting of undesirable events observed during or after normal or reasonably foreseeable use of a cosmetic product. AIM: The study was conducted to assess the adverse cosmetic events from a tertiary care hospital. PATIENTS/METHODS: The patients visiting the study site was reviewed and those who met the study criteria are enrolled in the study after administration of the informed consent. Study participants were followed on regular intervals either telephonically or hospital visits in order to determine the outcome. The causality assessment of the reported event was performed using Colipa and PLM method. RESULTS: During the study period 22,893 patients visited the dermatology department, in which 87 subjects were enrolled in the study. The incidence of adverse cosmetic event was 0.38%. Hair care products caused more events than body care products. In 73.56% of cases, the suspected cosmetic was withdrawn and all the study population received symptomatic treatment for the adverse events. Causality assessment of Using Colipa method, categorized 49.43% events as likely and using PLM method, 64.37% events were probable. Study couldn't identify any predictors of adverse cosmetic events. Median cost associated with the management of ACRs for hair care products and body care products were 716.62 (IQR: 1011.36-470) and 557.4 (IQR: 711.63-373.8). CONCLUSION: The study suggest need for approaches such as awareness programs among the cosmetic sellers, consumers and other stakeholders on cosmetovigilance needs to be developed and implemented.

INTRODUCTION: HIV is associated with various mucocutaneous manifestations which may be the first pointers toward HIV and can also be prognostic markers for disease progression. This study was done to note the different mucocutaneous lesions present in HIV and their relation to total lymphocyte count (TLC). METHODOLOGY: Three hundred and seventy-nine HIV patients attending the Department of Dermatology, Venereology, and Leprosy were included in the study. They were screened for the presence of any mucocutaneous lesions. TLC in patients presenting with mucocutaneous lesions was done and also CD4 count was done wherever possible. RESULTS: Among 379 patients, 53.8% developed mucocutaneous manifestations. Male: female ratio was 2.2:1. Majority of patients belonged to 20-39 years age group. Among mucocutaneous manifestations, oral candidiasis was the most common, followed by herpes zoster and dermatophytoses. Adverse drug reactions were noted in few. The majority of patients had TLC <1500/mm3 and CD4 <200. CONCLUSION: Mucocutaneous manifestations are common and have varied presentation in HIV/AIDS. Patients with mucocutaneous manifestations were clustered at lower TLC and CD4 count. Like CD4 count, TLC can be considered as a marker for disease progression.

INTRODUCTION: The American Diabetes Association includes acanthosis nigricans (AN) as an indicator of diabetes mellitus risk in overweight youth entering puberty. Some argue that AN is not an independent predictor of insulin resistance (IR), when body mass index (BMI) is controlled for. There is a paucity of studies on the association of AN and IR among children and young adults from India. Homeostatic model assessment-IR (HOMA2-IR), a computerized updated model, which is supposed to be superior to HOMA1-IR, has rarely been used for quantification of IR. METHODS: Sixty cases (irrespective of BMI), aged 2-24 years with AN, and 30 age- and sex-matched normal weight controls were included. A thorough clinical examination and grading of AN was done. BMI, fasting glucose levels, and fasting insulin levels were measured for all. HOMA-IR calculator V.2.2.3 was used to calculate IR. Those with HOMA 2-IR >1.8 were considered insulin-resistant. Lifestyle modifications were advised for patients with IR. RESULTS: The mean HOMA2-IR value in cases and controls was 2.422 and 1.322, respectively, which was statistically significant. Overweight and obese cases had 2.5 and 11.25 times higher risk of having IR, respectively, by logistic regression. The association of AN with IR was found to be statistically significant in normal weight cases when compared with controls (P = 0.045). Grade 4 of neck severity (P = 0.007), Grade 3 of neck texture (P = 0.001), and Grade 4 of axillary severity (P = 0.001) of AN were found to be significantly associated with IR. LIMITATIONS: The relatively small sample size may not reflect the accuracy of AN as a marker of IR. CONCLUSION: Acanthosis nigricans is associated with IR in both normal and obese. We propose that all children, adolescents, and youth with AN be screened for IR irrespective of BMI. Early identification and prompt lifestyle interventions may prevent or delay the onset of diabetes later.
RESUMEN
Acrodermatitis enteropathica (AE) is a rare congenital disorder owing to an abnormality with intestinal absorption and/or transportation of zinc. We describe two male siblings, who presented with evidence of both acute and chronic zinc deficiency, despite being diagnosed with AE very early in life. We wish to highlight the importance of sustained high-dose zinc supplementation and regular monitoring in AE cases. Proper counselling of parents about the need for life long supplementation and increasing requirements with age is essential.

BACKGROUND: Melasma is one of the most common and distressing pigmentary disorders presenting to dermatology clinics. The precise cause of melasma remains unknown. It is notably difficult to treat and has a tendency to relapse. Its population prevalence varies according to ethnic composition, skin phototype, and intensity of sun exposure. Due to its frequent facial involvement, the disease has an impact on the quality of life of patients. AIMS: To study the clinico-epidemiological pattern, dermascopy, wood's lamp findings and the quality of life in patients with melasma. SETTINGS AND DESIGN: Observational/descriptive study. MATERIALS AND METHODS: Patients with melasma were screened. History, clinical examination, Wood's lamp examination (WLE) and dermoscopy were done. Severity of melasma was assessed by the calculating melasma area severity index (MASI) score. Quality of Life (QOL) was assessed using MELASQOL scale with a standard structured questionnaire. STATISTICAL ANALYSIS: Descriptive, Chi-square test and contingency coefficient analysis. RESULTS: In 140 cases of melasma, 95 (67.9%) were females and 45 (32%) were males. Common age group affected was 31-40 years (65%). Majority were unskilled workers with average sun exposure of more than 4 hours (44%). Family history was observed in 18% cases. Malar type (68%) was the most common pattern observed. Mean MASI score was 5.7. WLE showed dermal type in 69% cases. Common findings on dermoscopy were reticular pigment network with perifollicular sparing and color varying from light to dark brown. Mean MELASQOL score was 28.28, with most patients reporting embarrassment and frustration. CONCLUSIONS: This study showed that melasma has a significant negative effect on QOL because though asymptomatic it is disfiguring affecting self-esteem. Dermoscopic examination did not help in differentiating the type of melasma.
