Erasmus syndrome is a rare syndrome accompanied by interstitial lung disease and scleroderma caused by silica exposure. There are a limited number of case reports in the literature. Awareness of this rare syndrome is important and occupational exposure should be questioned in patients presenting with scleroderma in our country, silica exposure is quite frequent and it should be kept in mind. Here, we report a case of a 41-year-old male patient presenting with interstitial lung disease, scleroderma, and serpiginous supravenous hypermelanosis caused by silica exposure who worked in the denim grinding for a short period of three months.

Context: Keloids are defined as scars that invade the adjacent tissues and rarely regress. In recent years, antimitotic drugs have been used in the management of keloids with promising results. This study highlights the effectiveness of 5-fluorouracil (5-FU) in keloids. Aims: To study the efficacy of intralesional 5-FU in keloids as a solo agent and in combination with triamcinolone acetonide and to study the side effects of both the drugs. Methods and Materials: A total of 30 patients with keloids were randomly allocated into two groups. Group A received 50 mg/mL of 5-FU intralesionally. Group B patients received a combination of 40 mg/mL of intralesional triamcinolone acetonide and 50 mg/mL of 5-FU. The patients were observed for immediate and delayed complications and the treatment was continued for a total of 3 months. Statistical Analysis Used: ANOVA, Mann–Whitney test, Fisher's test, Chi-square test. Results: The patients in both groups showed a significant reduction in the size and thickness of the lesions. The reduction in the length of keloid was highly significant in both the groups but in comparison, there was no statistically significant difference in the reduction of lesions among both the groups. Hence, both modalities of treatment can be claimed to be equally efficacious. The therapeutic response was good to excellent in most patients with only one patient opting out of the therapy in the 5-FU group due to the inability to tolerate the pain. The common side effects noted were pain, itching, ulceration, burning sensation, and bulla formation. Conclusions: 5-FU, both as a single agent or in combination with steroids is equally efficacious in reducing the keloid size. The side effects are lesser with the combination group.

Background and Objectives: Greying of hair is a regular feature of chronological aging that occurs in all regions and races. Premature canities is defined as minimum of five grey hairs in a person less than 20 years in Whites, 25 years in Asians, and 30 years in Africans. Premature canities is a common yet incompletely understood dermatological entity. This study aims at finding any association between premature hair greying (PHG) and parameters like hemoglobin (Hb), ferritin and calcium levels as well as its clinical profile. Methodology: This was a hospital-based cross-sectional analytical study conducted in the Department of Dermatology and Venereology, Trivandrum over one and half years. The study population consisted of 40 cases and 40 controls. Severity assessment, calculation of body mass index, and estimation of hemoglobin, serum ferritin, calcium, Random blood sugar, Anti Thyroid Peroxidase antibody, T3, T4, and TSH were done. Results: The mean age of the 40 patients was 17.14 years and most patients had onset of greying between 16 and 20 years. The male to female ratio was 1.2:1. A positive family history with a paternal predominance was noted. Vertex was the most common site of onset (42.5%), diffuse pattern was the most common clinical pattern (47.5%) and 60% had involvement of mild grade. Fourteen patients (35%) had abnormal investigations reports, in terms of low ferritin levels in 7 (17.5%), low calcium in 4 (10%) and a low Hb levels in 3 (7.5%) patients. Six (15%) patients had raised Anti TPO values. The association of PHG with low ferritin and raised anti-TPO levels were statistically significant. Conclusion: Low serum ferritin and raised Anti TPO levels may have a role in premature hair greying.

Atopic dermatitis (AD) is a chronic, relapsing inflammatory skin disorder affecting 15–20% of children and 1–10% of adults. Staphylococcus aureus (S. aureus) infection is the most frequent complication of AD and is involved in the worsening of the disease. Systemic and topical antibiotics are used in the treatment for AD but there are concerns over increasing resistance. Bleach (sodium hypochlorite, NaOCl) baths are an inexpensive, widely accessible, alternative antibiotic treatment that may not worsen antibiotic resistance. Bleach baths are used as adjunctive treatment in AD patients to treat superinfections, although their mechanism of action is not well understood. Balancing safety concerns with efficacious treatment should be important especially for AD where the majority of patients are in pediatrics age groups. Studies available in PubMed databases were included in this review. Most suggested bleach bath improves clinical symptoms of AD and restores surface microbiome by eradicating bacteria, most notably S. aureus. Some studies have noted that this antimicrobial effect has reduced the need for topical corticosteroids. In addition, bleach seems to have strong anti-inflammatory and antipruritic effects. Overall, bleach baths seem to be safe on human skin, without disrupting the epidermal barrier function. The review concluded, although there are some advantages of use of bleach baths, more studies to investigate long-term efficacy and safety of bleach baths are required before fixing its role in the treatment of AD especially in the context of the Indian scenario.

Several cutaneous diseases can present with annular lesions, making a distinction by physical appearance alone challenging. They can be distinguished into infectious and non-infectious, and common and uncommon annular dermatoses. Common non-infectious diseases include granuloma annulare, urticaria, and subacute lupus erythematosus. In addition, there are rare non-infectious non-neoplastic annular dermatoses whose nosographic attribution is established, including annually recurring erythema annulare centrifugum (EAC) and annular erythema in Sjögren syndrome and others whose nosographic positioning is still debated. They are neutrophilic figurate erythema, palpable migratory arciform erythema, eosinophilic annular erythema, and annular lichenoid dermatitis of youth. Their etiopathogenesis is largely unknown, although immune-mediated mechanisms are likely involved. It is difficult to establish if they are variants of reaction patterns or separate clinic-pathological entities. In fact, EAC and annually recurring EAC may represent different aspects of the same disease. Palpable migratory arciform erythema is hardly distinguishable from EAC deep type, Jessner-Kanof disease, and lupus tumidus. Neutrophilic figurate erythema and eosinophilic figurate erythema are clinically very similar and differing only in the relative proportion of eosinophils and neutrophils.

Background: Palmar hyperhidrosis is characterized by excessive sweating beyond the physiological needs of the patient's body and the most frequent form is primary or essential. Different treatments protocols have been proposed to control or decrease sweating. Aims and Objectives: This study aimed to compare the efficacy and safety of oral oxybutynin versus topical aluminum chloride hexahydrate (ACH) in treating primary palmar hyperhidrosis. Also, to assess quality of life (QOL) as a measure of improvement of hyperhidrosis state. Materials and Methods: Patients were randomized using the block randomization with sealed envelope method into two treatment groups; oral oxybutynin group and topical ACH group. Hyperhidrosis Disease Severity Scale (HDSS) was used as a primary outcome measure to assess the efficacy of the drug in both groups. Clinical grading and the QOL were used as secondary outcome measures. The safety was evaluated by recording side effects in the follow-up visits. Results: HDSS, clinical grading and QOL score showed a statistically significant improvement in the oral oxybutynin groups. One week after stoppage of treatment, the symptoms recurred again in both groups with return of HDSS and QOL scores to pretreatment levels. The most common side effects were dry mouth (65.8%) and itching (65.0%) for oral oxybutynin group and topical ACH group; respectively. Conclusion: Treatment of primary palmar hyperhidrosis with oxybutynin is a good initial alternative for treatment given that it gives better results and much more improvement in QOL when compared to topical ACH. QOL questionnaire and clinical grading should also be considered as useful tools in the assessment of response to treatment.

The progression of allergic diseases with the development of atopic dermatitis and food allergy in infancy and subsequent asthma and allergic rhinitis in the later childhood is known as 'atopic march'. There have been many arguments in favour of and against this concept. This article reviews the latest epidemiology, immunological mechanisms and translational implications in clinical practice and research, which is relevant to the dermatologists. The role of skin as a site of initiation and the potential for interventions on skin that may prevent subsequent allergic diseases is also highlighted.

Context: Psoriasis is a chronic inflammatory dermatosis associated with an increased risk of cardiovascular disease and atherothrombosis. Aims: This study was conducted to assess the levels of various hemostatic and coagulation parameters in psoriasis and their correlation with disease severity. Settings and Design: This was a hospital-based observational study. Methods and Material: Seventy-five patients with psoriasis and seventy controls were included in the study. History taking, clinical examination, and calculation of Psoriasis Area and Severity Index (PASI) were done. Blood analysis for Platelet count (PC), mean platelet volume (MPV), Vitamin B12, Thrombin Time (TT), Prothrombin time (PT) and Activated partial thromboplastin time (APPT) were done in both groups. Results: MPV which is a marker of inflammation and platelet activation was significantly increased in cases and positively correlated with the disease severity. Vitamin B12 is an important cofactor in homocysteine (Hcy) metabolism and correlates inversely with serum Hcy which is a known atherothrombotic marker. Vitamin B12 levels were significantly decreased in the cases with a significant negative correlation between Vitamin B12 level and PASI. There was also a significant decrease in serum level of PT, aPTT and TT in cases as compared to controls; however they showed no significant correlation with PASI. Conclusions: Inflammation in psoriasis may drive the process of abnormal platelet activation and coagulation abnormalities thus predisposing psoriatic patients to an atherothrombotic state and increasing the cardiovascular risk in psoriatic patients.

Background: The lack of objective methodologies and open datasets for the evaluation of the algorithms complicates the objective evaluation by specialists and hinders the widespread use of this technology in health care. The purpose of this study was to estimate the accuracy of Skinive's algorithm 2020 version, then, after an algorithm improvement in 2020–2021, to show a statistically significant decrease in neural network errors in the risk assessment of skin pathologies in 2021. Methods: The Skinive neural network uses a machine-learning algorithm to calculate the risk rating of skin pathologies. For this study, we used Skinive's algorithm 2020 and 2021 versions trained on 64,000 and 115,000 images, respectively. Three validation datasets were used to assess the sensitivity of the algorithm: precancer + cancer, viral skin pathology, acne, containing 285 images in each set. The specificity has been calculated on a separate validation set containing 6,000 benign neoplasm cases. Results: The sensitivity of the Skinive neural network in detecting malignant neoplasms was 89.1% and 95.4% in 2020 and 2021, respectively. The specificity of Skinive's neural network in determining benign neoplasms was 95.3% in 2020 and 97.9% in 2021. For all skin neoplasms, in 2020, the sensitivity was 95.3%, and specificity was 93.5%; in 2021, these were 97.9% and 97.1%, respectively. Conclusions: The results of sensitivity and specificity of the Skinive neural network indicate that the algorithm is highly accurate in detecting various neoplasms and skin diseases. After improving the algorithm, we showed a statistically significant decrease in the number of neural network errors in determining the risks of skin pathologies.

Background: The etiopathogeny of chronic spontaneous urticaria (CSU) is not well defined. Allelism in glutathione S-transferase GSTM1 and GSTT1 has been suggested as a risk factor. Desloratadine is the first-line treatment for this disease. Objective: This study aimed to investigate the efficacy of a first-line treatment: desloratadine 5 mg/day on antioxidant status and clinical assessment in Tunisian patients with CSU and to identify possible associations between GSTT1 and GSTM1 genotypes and susceptibility to CSU. Methods: Sixty patients with CSU and 60 age- and gender-matched healthy controls were included in the study. We calculated the urticaria activity score (UAS) and assessed the antioxidant parameters (total antioxidant status [TAS], glutathione S-transferase [GST], SOD, CAT, GPx]). Multiplex PCR was performed to find the relationship between GSTM1 and GSTT1 polymorphisms with CSU susceptibility. Results: At baseline, GST, GPx, CAT, SOD activities, and TAS were significantly lower in CSU patients compared to healthy controls (P < 0.05). After treatment, GST, GPx, CAT, SOD activities and TAS were significantly increased in patients compared to those before treatment (P < 0.001). We observed a significant association in null alleles of GSTM1. Before treatment, GST activity was significantly lower in patients having GSTM1+ genotype than those having GSTM1- genotype (P = 0.001). After treatment, TAS and antioxidant enzymes GST, GPx, SOD, and CAT were significantly elevated in patients having GSTM1- genotype than those having GSTM1+ genotype (P < 0.05). Conclusion: These results suggest the impact of GSTM1 and GSTT1 on CSU susceptibility and desloratadine efficacy in Tunisian patients.

Introduction: The dynamics of sexually transmitted infections (STIs) are influenced by sexual behaviour (age of first sexual exposure, number of sexual partner/s, sexual orientation, mode of intercourse, addiction, occupation, correct and consistent use of condom). The presence of the human immunodeficiency virus (HIV) influences the clinical pattern of STIs and the course of disease too. Objective: Our study was conducted to find the prevalence of STIs among attendees of a designated STI/RTI clinic (DSRC) with the description of clinico-demographic profile and sexual behaviour and association of HIV seropositivity with STIs. Methods: Ours was an institution-based cross-sectional study conducted at DSRC after obtaining ethics committee approval and consent from patients. Clinical diagnosis, demographic profile and sexual history were obtained after maintaining audio-visual privacy. Statistical Analysis: Medcalc, version 10.2 was used. Results: Among 167 patients attending DSRC during the study period, 76 having sexual dysfunctions were excluded. The major STIs diagnosed were primary syphilis (6.59%), secondary syphilis (2.2%), herpes genitalis (42.86%), condyloma acuminata (26.37%), molluscum contagiosum (5.49%), genital candidiasis (7.69%), bowenoid papulosis (3.3%), genital scabies (4.4%) and chancroid (1.1%). Sexual orientations were heterosexual (64.83%), lesbian (1.1%), gay (12.1%), bisexual (17.58%) and with an animal partner (4.4%). Among the total study population, 8.8% was rapid plasma reagin (RPR) reactive and 12.1% was Integrated Counselling and Testing Centre (ICTC) reactive. Among the total patients who used condoms (n = 49), only 15 (16.4% of total participants) used condoms correctly and consistently. Peno-vaginal mode of intercourse (n = 78) was found to be most common followed by oro-insertive (n = 42), oro-receptive (n = 34), ano-insertive (n = 24), ano-receptive (n = 17) and digital insertion (n = 20). Conclusion: Sexual behaviour influences the disease outcome in patients with reproductive tract infection (RTI)/STI.

The One Health concept recognizes that the health of people is connected to the health of animals and the environment. A 21-year-old female patient presented with several nodular and cystic swellings on the front and sides of her neck for the past 2 years. Histopathology showed sulfur granules surrounded by neutrophils in an area of granulation tissue with filamentous Gram-negative bacilli in the granules. She was a regular cattle handler since her childhood, and one of her cows on the farm had died from a similar sort of illness 2 years back at the same period when her disease began. We made a provisional diagnosis of actinobacillus infection and started the patient on doxycycline 100 mg twice daily. With this treatment, the patient showed an excellent clinical response and her condition healed with resultant scarring within 7 weeks of treatment.

Primary cutaneous diffuse large B-cell lymphoma-leg type (PCDLBCL-LT) is characterized by diffuse monotonous proliferation of centroblasts and immunoblasts. It commonly presents as erythematous to violaceous nodules on one or both the legs and has a poor prognosis. We report the clinico-dermoscopic-pathological features and therapeutic response of a rare case of PCDLBCL-LT in a 62-year-old diabetic man, who presented with multifocal plaques, one lobulated and two arcuate-shaped, on the face and scalp. During the investigation, one of the plaques had eroded the underlying bone without any evidence of malignant cells in the cerebrospinal fluid. He was successfully treated with R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone) along with intrathecal methotrexate.

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.

There is a dearth of data regarding the safety and timing of the severe acute respiratory syndrome coronavirus 2 (SARS-COV-2) vaccination of patients on immunosuppressive or immunomodulatory therapies. However, data from other vaccine trials may be extrapolated to get an idea regarding the recommendation of SARS-COV-2 vaccines. All the novel SARS-COV-2 vaccines are non-live, thus ensuring the safety of the vaccines. However, the vaccines may not be able to generate an equipotent immunogenic response in patients receiving immunotherapeutics, in comparison to those who are not. We have attempted to put forward certain statements, with respect to SARS-COV-2 vaccination of patients who are on treatment for different dermatological conditions. However, the risk-benefit ratio must be discussed between the patient and the physician, and the final call should be individualized.

Background: Allergic contact dermatitis (ACD) is a type IV hypersensitivity reaction, and The European Standard Series (ESS) Patch Test (PT) is widely used in determining the possible responsible allergens causing ACD. The dynamic nature of the industrial products, socioeconomic and environmental factors cause the frequency of common allergens to change over the years and among different regions. Aims and Objectives: This study aimed to retrospectively evaluate the results of ESS PT of our centre in the last decade, and determine the current spectrum of allergens and their clinical relevance. Materials and Methods: The data of patients who underwent ESS PT in our clinic between January 2010 and March 2020 were included in the study. The patient files were examined retrospectively. The clinical relevance was evaluated according to the COADEX system. Statistical analysis used: SPSS for Windows version 23.0 software program. Results: The data of 1037 patients [623 (60.1%) female, 414 (39.9%) male] were analysed. The mean age was 38.34 ± 14.55 years. The five most common allergens were nickel sulphate (23.1%), cobalt chloride (12%), potassium dichromate (9.5%), Fragrance mix II (7.3%) and balsam of Peru (5.7%). According to the COADEX coding system, current relevance was detected in 319 (49.3%) of 646 patients who had a positive reaction to any substance in the patch test. Conclusion: Our study showed that with increasing awareness in society, the tendency to avoid some well-known allergenic substances and consumer products causes changes in common allergens. These results prove the value of long-term surveillance of contact allergy.

Background: Joint replacement is an important surgery for replacing a damaged joint with prosthesis. Implants used for joint replacement are made of metal, plastic, and ceramic. Skin reactions, such as dermatitis, can occur due to a hypersensitivity to these external substances. Aims: The aim of this study was to find the relationship between joint replacement and dermatitis. Methods: A nationwide population-based retrospective cohort study was performed using the National Health Insurance Service Database of the Republic of Korea. A total of 40,218 patients who underwent joint replacement were enrolled as the operation group and 40,218 controls were also enrolled. A cox proportional hazard regression model, and Fine and Gray regression model were used to compare the risk of dermatitis between the two groups. Results: Dermatitis occurred in 9.2% of the operation group and 9.1% of the control group, and no statistical difference was observed between the two groups. According to the Cox proportional hazard regression model, and Fine and Gray regression model, the risk of dermatitis did not increase in the operation group compared to that in the control group. However, the risk of dermatitis increased 1.20-fold in the operation group compared to that in the control group aged <60 years according to the Fine and Gray regression model (95% confidence index (CI) = 1.05–1.37, P = 0.0008). Conversely, no difference in dermatitis risk was observed between the two groups aged ≥60 years. Conclusions: We found that the risk of dermatitis increased after joint replacement in those aged <60 years.

Acrodermatitis enteropathica (AE) is a rare inherited form of defective zinc absorption usually manifesting as eczematous and erosive dermatitis preferably over periorificial and acral areas which at times mimics various hereditary palmoplantar keratodermas (PPK). We reported a 6-year-old boy who presented with hard plaques over both palm and sole, and periorificial areas, and flexion attitude of digits without any history of diarrhea and prolonged illness. The patient improved dramatically with zinc supplementation including correction of flexion deformities of the fingers. There was improvement of serum alkaline phosphatase level within 3 months. The lesions reappeared again whenever there was discontinuation of therapy for few weeks, thus confirming it to be zinc deficiency dermatoses. This kind of manifestation has rarely been described in earlier literature.

Introduction: Viral warts are a group of dermatological diseases caused by human papillomavirus (HPV). Several studies have demonstrated an association between HPV infections and oxidative stress. Thiols are important components of cellular redox homeostasis as antioxidant molecules in the organism. Aim: This study aimed to investigate the role of oxidative stress in patients with HPV infection by analyzing native thiol/disulfide homeostasis. Material and Methods: Forty-two patients with HPV infection and 40 healthy subjects were analyzed for the levels of native thiols, total thiols, and disulfide. Disulfide/native thiol, disulfide/total thiol, and native thiol/total thiol ratios were also calculated. Results: Disulfide and total thiol levels were higher in the patients compared to the healthy controls. The disulfide/native thiol ratio was also higher in the patient group. Native and total thiol levels decreased with the increasing duration of the disease. Conclusion: The native thiol/disulfide homeostasis was shifted toward disulfide in the patients' group, indicating the existence of oxidative stress in HPV infection.

Background: Cutaneous leishmaniasis (CL) is endemic in Yemen. CL displays a spectrum of typical and atypical morphologies yet understudied in the central and southwest regions of Yemen. Aims and Objectives: To identify the typical and atypical clinical phenotypes of CL in the central and southwest regions of Yemen. Materials and Methods: A survey of 145 patients who visited Prof. Al-Qubati Clinic in Taiz between 2010 and 2015, was conducted. Results: Children and residents of the rural areas were at high risk of exposure to the insect vector. The typical phenotype was single (67%), facial (58%) and ulcerated nodule (35%). Other usual phenotypes were small ulcers (21.4%) and non-ulcerative papules and nodules (21%). Unusual phenotypes constituted 12% of the cohort and included psoriasiform, eczematous, erysipeloid, lupoid, verrucous, large ulcerative, leishmania recidivens, satellite, granulomatous infiltrative and hyperkeratotic plaques. Mucous membrane involvement was evident in 10.6% and was also polymorphic. Conclusion: CL has many morphologic patterns in central and southwest regions of Yemen, some are clinically deceptive.

Background: Early forecasting of any pathological process is of great significance from both medical and economic point of view. An illness requires much more attention in the light of exhaustion of resources of the body, and a doctor should be maximally aware of the near and far future of a patient. In this regard, the preparation of forecasting programs on a mathematical basis would be a rational and, most probably, the only true approach to the solution of forecasting. Aims and Objectives: The aim of the article is to study the forecasting of atopic dermatitis (AD) in newborns. Methodology: The authors studied 109 clinical and laboratory indicators in children without and with AD. Discriminant analysis was used as an algorithm for the resolution of diagnostic issues. Results: The main indicators acceptable as a forecasting criterion in the formation of AD in children were defined. The sensitivity, specificity, and general diagnostic value of statistically valid differing factors in the formation of AD were studied. Key rules of the forecast were formed after processing all indicators through the KU–Kruskal–Wallis discriminant criterion, a universal computer method. Conclusion: It was concluded that the power of influence of rhinitis, cluster of differentiation 31, mucin 2, and intestinal trefoil factor 3 are higher in the AD model.

Background: Cutaneous leishmaniasis (CL) is a parasitic infection transmitted by the female sandfly, which has limited knowledge in non-endemic areas. Aims: To predict the epidemiological and clinical characteristics of CL cases on treatment during the period of Syrian refugees' settlement. Methods and Material: The epidemiological and clinical data of 81 patients with CL who were admitted to the Istanbul Bagcilar Research and Training Hospital between March 2010 and April 2017 were conducted as a retrospective cohort study. A logistic regression analysis was performed. Results: Most detected demographics were Syrians (n = 56, 69.1%), ages <= 18 (n = 37, 45.7%), males (n = 49, 60.5%), elementary-school graduates (n = 35, 43.2%), and $500–750 income (n = 42, 51.9%). Most detected clinical characteristics were head/neck location (n = 38, 46.9%), acute-dry localized type (n = 71, 88%), crusted-papule (n = 79, 97.5%), and two lesions (n = 29, 35.8%). Means for age, family population, and session were 25.28 ± 20.90, 7.04 ± 2.03, and 11.27 ± 3.52, respectively. Majority of patients were admitted in 2014 and June. Significant factors by age were location, lesion type/number, and disease-duration. Lesion number ≥10, ages ≥41, crusted-nodule, cicatrix, and dissemination increased in session numbers, whereas crusted-nodule showed significant predictivity (P = 0.01). Conclusion: Location, lesion type/number, and disease duration may change by age in CL cases, whereas the presence of a crusted nodule may have a predictive effect on the number of treatment sessions.

Background: Acquired fibrokeratoma (AFK) is an uncommon, sporadic, benign, acquired, slow-growing dermo-epidermal tumour. Aims and Objectives: The purpose of this study was to summarize the demographic, clinical characteristics and treatment outcomes of patients with AFK in a tertiary care centre in South India. Methods: We evaluated the records of 26 patients with AFK who were diagnosed and treated in our centre between January 2017 and December 2021. The retrospective data related to age, sex, occupation, consistency, duration of lesions, history of trauma, anatomical site, morphological appearance, histopathological type, treatment provided and recurrence were taken into account and analysed. Results: Of the 26 patients, there were 21 males and 5 females. Fingers (n = 23) were the most common site involved, followed by toes (n = 2) and palm (n = 1). A total of 18 patients had finger-like projected lesions and eight patients had dome-shaped lesions. In histopathology, Type I AFK type was observed in 16 cases and Type II in 10 cases. Conclusion: We believe that our study would contribute by providing the clinical, histopathology and treatment outcomes of this uncommon dermo-epidermal tumour. The frequency of this condition is often underestimated as it is misdiagnosed for many other dermatological conditions.

Dermatitis as an initial manifestation of cystic fibrosis (CF) is unusual. The eruption is usually first noted in the perineum anywhere from several days to few months after birth. It subsequently spreads to the extremities and trunk. We report a 2-month-old male baby who presented with failure to thrive, hypoproteinemia, anemia, and a cutaneous eruption resembling acrodermatitis enteropathica. Oral zinc supplementation resulted in temporary resolution of the dermatitis. A further workup revealed the diagnosis of CF. The rash was responsive to nutritional and pancreatic enzyme supplementation.

Background: Cytotoxic T lymphocyte-associated protein-4 (CTLA-4) or CD152 is an inhibitory receptor expressed constitutively on CD4+CD25+ T regulatory lymphocytes (Treg) and transiently on activated CD4+ and CD8+ T lymphocytes. Association of CTLA4 gene polymorphisms with Systemic Lupus Erythematosus (SLE) has been reported in south Indians, but not in north Indians. This study aims to investigate CTLA4 gene polymorphism and its association with the occurrence of SLE, its clinical manifestation and serological markers in north Indians. Methods: This cross sectional study was done in a tertiary health care centre in north India. Patients reporting to the hospital and diagnosed with systemic lupus erythematosus were included in study. +49 A/G (snp- rs231775) CTLA4 gene polymorphism was analysed in 41 SLE patients and 21 matched healthy controls by real time PCR method. ANA (Antinuclear Antibody), anti dsDNA, Interferon-γ (IFN- γ), TGF-β, IL-10 were measured by ELISA kits. Complement (C3 and C4) and immunoglobulins (IgA, IgG, IgM) estimation were done with the turbidometry method. Chi-square test was used for comparison between groups and odds ratio with 95% confidence interval was calculated to estimate the associated risk. Results: A/A genotype was most common (51.2%) followed by the A/G genotype (46.3%) and G/G genotype (2.4%, detected in only 1 patient). The frequency of A allele was 74.4%, while of G allele was only 25.6%. A/G genotype SLE patients showed a higher risk (odds ratio 37.5, 95% CI- 6.048-232.51) of developing edema compared to A/A genotype patients. There was no statistically significant association of various CTLA4 genotypes with the occurrence of SLE and serum markers. Conclusions: A/A was the most common CTLA4 genotype in both SLE patients and healthy controls of north India. Contrary to the previous report in south Indians, there was no statistically significant association between CTLA4 genotype and occurrence of SLE in north Indians. Only the presence of generalised edema was found significantly associated with the A/G genotype.

Background: Since the occurrence of the coronavirus disease-2019 pandemic, healthcare workers (HCWs) have been strictly adhering to infection control practices within healthcare facilities. However, regular use of personal protective equipment (PPE) and hand hygiene have led to increased prevalence of skin damage, subsequently impacting the quality of life (QoL). Objective: To analyse the connection between skin damage and the QoL among HCWs in a multicenter setting in Indonesia. Methods: A cross-sectional survey was conducted among HCWs working in hospitals in Banten Province, Indonesia. The data was obtained using a reliable self-reported questionnaire (Cronbach α 0.765) and a validated Indonesian version of the Dermatology Life Quality Index. Results: A total of 113 respondents (56.5%) who experienced at least one self-perceived PPE-related skin damage and had worn PPE of any level within the last 7 days were analysed. The mean age ± SD of respondents was 26.09 ± 6.22 years old, while the mean DLQI score ± SD was 5.46 ± 4.88, with a median of 4.0 (range, 0-24). The regression model showed that the level of PPE used (P < 0.05) to be a significant risk factor. Conclusions: Skin damage due to PPE affects HCWs physically and emotionally. It is crucial to recognise its impact on life and reinforce awareness, prevention, and treatment of skin damage. Dermatologist referral and intervention should be considered for optimum management.

Context: The relationship between alopecia areata (AA) and emotion regulation difficulty has not yet been fully explained. Aims: The aim of the study was to investigate the levels of anxiety and emotion regulation difficulty in children diagnosed with AA. Settings and Design: This case-control study was done in the university setting. Methods: Behavioral tests measuring anxiety and emotion regulation difficulties, and the measures assessing AA severity were applied to 32 AA patients consulted at Dermatology Clinic of Yozgat Bozok University. A control group was formed of 36 healthy children. Statistical Analysis Used: Kolmogorov-Smirnov normality test, Mann-Whitney U test and Pearson's and Fisher's Chi-square tests and Spearman's correlation test. Results: Evaluation was made of a total of 68 subjects (32 patients, 36 healthy subjects). The Difficulties in Emotion Regulation Scale (DERS)-total score and the DERS-clarity subscore were statistically significantly higher in the control group than in the patient group (P = 0.021, P = 0.003, respectively). No significant difference was determined between the two groups in respect of anxiety levels. No correlation was determined between disease severity and the scales. It was determined that as disease duration increased, so the DERS-non-acceptance subscale score increased, and with an increase in age, the SAI score of the AA patients increased. The DERS-impulse subscale score was seen to be statistically significantly higher in the boys with AA than in girls (P = 0.030). Conclusions: The results of this study showed that a visible, chronic, recurrent disease such as AA is not always seen with high psychiatric comorbidity and that together with the presence of the disease, patient age and disease duration are also important. It can be considered that AA may have been affected by the location, time and conditions of the study.

A 30-year-old woman presented with an acute-onset high-grade fever (103°F), multiple episodes of throbbing abdominal pain in the right quadrant, and pustular red lesions on the left leg. The radiological findings were suggestive of autoimmune cholangitis and pancreatitis. The skin lesions recurred on different portions of the body, and histopathological findings showed lobular and septal lymphohistiocytic infiltrate without vasculitis. The epidermis had focal ulcerations, and the dermis showed the presence of subcutaneous fat and an infiltrate of lymphocytes, histiocytes, and neutrophils (described as lobular and septal panniculitis without vasculitis). Based on the clinical and histopathological features, a diagnosis of migratory panniculitis was made. The patient was managed with analgesics, antibiotics, and a long course of steroids; the patient responded well to these medications. To the best of our knowledge, this is one of the first case reports of migratory panniculitis associated with IgG4-related disease. Patients with migratory panniculitis should be investigated for the presence of IgG4-related autoimmune disease. However, steroids remain the drug of choice when these conditions occur together.

Background: Atopic dermatitis (AD) is a chronic inflammatory skin disease. Skin and gut are the organs that first encounter antigens and environmental triggers. The mechanisms behind the relation between skin and gut immune responses in AD have not been identified yet. Aims and Objectives: To investigate mucosa-associated epithelial chemokine (MEC/CCL28), thymus-expressed chemokine (TECK/CCL25), periostin and zonulin levels in infants with AD. Materials and Methods: Children under one year old participated in the study. We used a propensity matching score. We included 39 infants who had active AD lesions at the time of evaluation. Serum MEC/CCL28, TECK/CCL25, periostin and zonulin levels were measured. Results: We examined age and sex matched 39 infants with AD and 39 healthy infants. Median value of zonulin was lower in infants with AD [49.2 (27.1–71.8) ng/mL] compared to healthy controls [58.5 (27.3–80.8) ng/mL] (P < 0.001). Infants with zonulin levels ≤55.15 ng/mL had 11.64 times more risk of developing AD than the infants with zonulin levels >55.15 ng/mL. Infants whose MEC/CCL28 levels were ≥8.3 ng/mL had 5.83 times more risk of developing AD than the infants with MEC levels <8.3 ng/mL. Duration of AD and SCORAD index score did not show correlation with MEC/CCL28, TECK/CCL25, periostin and zonulin levels. Conclusion: Low zonulin levels and high MEC/CCL28 levels in infants may show an increased association with AD.

Background: Acne vulgaris (AV) is among the common skin diseases for which patients refer to complementary and alternative medicine (CAM). Aims and Objectives: To investigate the approaches to CAM methods and factors believed to increase the disease in 1,571 AV patients. Materials and Methods: The sociodemographic characteristics of the patients and disease severity according to the Food and Drug Administration criteria were recorded. The Cardiff Acne Disability Index (CADI) was used to assess the impact of acne on the patient's life and the history of CAM use was noted. The patients also listed the factors that they thought worsened their disease and reported their gluten-free diet experiences. Results: Of all the patients, 74.41% had a history of using CAM methods. CAM use was significantly higher in women, patients with severe AV, those with a higher CADI score and non-smokers. As a CAM method, 66.37% of the patients reported having used lemon juice. The respondents most frequently applied CAM methods before consulting a physician (43.94%), for a duration of 0–2 weeks (38.97%). They learned about CAM methods on the internet (56.24%) and considered CAM methods to be natural (41.86%). The patients thought that food (78.55%) and stress (17.06%) worsened their disease. They considered that the most common type of food that exacerbated their symptoms was junk food (63.84%) and a gluten-free diet did not provide any benefit in relieving AV (50%). Conclusion: Physicians need to ask patients about their CAM use in order to be able to guide them appropriately concerning treatments and applications with a high level of evidence.

Background: Acne is becoming more prevalent in adults, particularly women across the globe. Although previous studies have compared clinical and epidemiologic characteristics of adolescent and adult acne, an adequate understanding of the quality of life (QoL) of adult acne patients and associated comorbidities are still lacking. Objectives: We sought to compare the differences between adolescent and adult patient groups, regarding gender, socio-clinico-demographic factors, and comorbid associations, as well as their relatedness with life quality. Methods: This is a cross-sectional study with 1013 acne patients. Data on the severity, onset and location of acne, sex, family history of acne, smoking and alcohol habits, medication history, presence of seborrhea, and other comorbidities were collected. We employed the classification used by the American Academy of Dermatology for assessing acne severity. To assess the QoL in the patients, the Dermatology Life Quality Index (DLQI) score was used. Results: Of the 1013 patients included in this study; 380 (female: 333, male: 47) were adult, and 633 (female: 535 and male: 98) were adolescent cases. The median total DLQI scores of adult and adolescent groups were not significantly different. Our results showed that factors such as age, gender, duration, body mass index, family history, and psychiatric disorders exhibited no impact on QoL in both adolescents and adults. Age of onset was correlated with DLQI scores in the adult group. The main influencers of DLQI in the adult group were allergic disorders, hormonal imbalances, and previous treatment history. Besides, major influencers in adolescent patients were acne severity, acne location, hirsutism, hyperseborrhea, premenstrual exacerbation, menstrual irregularities, previous treatment history, and smoking. Conclusions: The findings of our current study have shown that DLQI has been influenced by different factors in adolescents and adults that should be kept in mind.
