Background: There is a rising prevalence of dermatophyte infection especially in the tropics. It has been observed that the antifungals are not as effective as they used to be. Aims: To determine the effectiveness of terbinafine and itraconazole in different doses and in combination in the treatment of tinea infection. Materials and Methods: Study design was a randomized parallel group trial. Patients were randomly divided into five parallel arms in which two of the standard drugs in recommended doses were compared with their double doses and with combination of both the drugs. Patients were followed up every 2 weeks. Outcomes were assessed at 4 and 8 weeks. Cure was considered as complete clinical resolution of the lesions. Fungal culture and sensitivity were done by disk diffusion method for all patients. Parametric one-way analysis of variance (F test) and Chi-square test were used for the analysis. Results: Two-hundred seventy-five patients were included in the study. Itraconazole containing groups showed significantly higher cure rates than terbinafine only groups both at 4 and 8 weeks (P < 0.001). Itraconazole containing groups, when compared against each other, were not found to be significantly different. The outcomes between terbinafine only groups were also not significantly different. Cure rates at 8 weeks were found to be greater than that at 4 weeks for all groups which were found to be highly significant (P < 0.001). Conclusions: Itraconazole seems to be more effective than terbinafine. There is no benefit in increasing the dose or using a combination regimen in the treatment of tinea. Prolonged duration of treatment is required for complete cure.

Background: Female pattern hair loss (FPHL) is an important cause of hair loss in adult women and has a major impact on patient's quality of life. It evolves from the progressive miniaturization of follicles that leads to a subsequent decrease of hair density, leading to non-scarring diffuse alopecia, with characteristic clinical, dermoscopic, and histological patterns. Vitamin D receptor (VDR) is expressed in follicular keratinocytes and dermal papilla cells and is shown to have important role in hair growth and regulation of hair cycle. VDR polymorphism was not extensively investigated in hair disorders including FPHL. Aim: To investigate the association between VDR gene polymorphism (Cdx-1 and Taq-1) and FPHL to explore if these polymorphisms affect the disease occurrence or influence its clinical presentation. Methods: A case-control study was conducted on 30 female patients with FPHL and 30 age-matched female healthy subjects, as a control group. Degree of hair loss was assessed by Ludwig grading. VDR gene polymorphisms, Taq-1 and Cdx-1 were investigated by real time polymerase chain reaction. Results: CC genotype, TC genotype, and T allele of Taq-1 were more prevalent in FPHL patients than in control group. They increased disease risk by 12.6, 2.1, and 2.9 folds, respectively. AA genotype, GA genotype, and G allele of Cdx-1 were significantly more prevalent among FPHL patients than in control group. They increased disease risk by 7.5, 5.2, and 5.5 folds, respectively. Conclusion: Taq-1 and Cdx-1 can be considered as risk factors for FPHL. They may play role in disease persistence rather than disease initiation. This association may be explained by failure of new anagen growth and decreased proliferation of hair follicle stem cells. Further studies are recommended to confirm current findings.

Background: Radiodermatitis is a frequent side effect of breast cancer radiotherapy (RT). Treating radiation oncologist should know the prevention and treatment of every grade of radiodermatitis. Aims: The aim of this study was to compare the topical corticosteroid and moisturizer usage in breast cancer RT. Materials and Methods: Fifty patients with early-stage breast cancer undergoing breast-conserving surgery referred to our department for adjuvant RT between October 2009 and October 2016 were compared with regard to topical steroid or moisturizer usage. Patients were followed up weekly after the start of treatment. Results: Mean age was 46 years. Twenty-four patients had stage 1 breast cancer and 26 patients had stage 2 disease. KPS (Karnofsky performance score) was 100 for all patients. Five patients (20.8%) had grade 2 and seven (29.1%) patients had grade 1 acute radiodermatitis in the first group. Eleven (42.3%) patients had grade 2 and 12 (46.1%) patients had grade 1 acute radiodermatitis in the second group. Thirteen (54.1%) patients in the first group had no acute radiodermatitis and three (11.5%) patients in the second group had no acute radiodermatitis. No patient in either group experienced grade 3 radiodermatitis. Conclusions: Daily use of topical betamethasone for breast cancer RT improves dermal sparing, reduces acute radiodermatitis, and may be recommended for patients receiving RT to the breast.

A 30-year-old female patient presented with progressive reticulate pigmentation of the neck, upper chest, back, cubital fossa, and axillae since the age of 15 years. The patient also complained of recurrent multiple tender nodules and plaques associated with sinuses and pus discharge over the axillae, groins, and buttocks which healed with scarring for 4 years. There were multiple pitted scars and hyperpigmented macules over the perioral area and cheeks. Scattered comedo-like lesions were present over the upper back, chest, cubital fossae, and buttocks. Histopathology from the pigmented lesion revealed thinning of the suprapapillary epidermis, epidermal hyperplasia with finger-like elongation of the rete ridges, and increased pigmentation of their lower part, suggestive of Dowling–Degos disease (DDD). Biopsy section from comedonal lesion showed dilated infundibulum and antler-like rete ridges suggestive of follicular DDD. We report a case of DDD with follicular involvement and hidradenitis suppurativa (HS) which is a rare association and can be explained on the basis of single underlying defect in follicular epithelial proliferation. DDD-HS has been shown to result from mutations in PSENEN, encoding a critical component of the γ-secretase complex.

Background: The liver and skin are the most common organs involved in Stevens–Johnson syndrome/toxic epidermal necrolysis (SJS/TEN). Drug reactions rarely affect both organs concurrently. The clinical features, risk factors, and prognostic markers of drug-induced liver injury (DILI) in patients with SJS/TEN are not well studied. Materials and Methods: The clinical features, risk factors, and prognostic markers of DILI in patients with SJS/TEN hospitalized at the dermatology department of our hospital from January 2009 to December 2018 were retrospectively analyzed. Results: A total of 298 patients with SJS/TEN were enrolled in this study. Of them, 40 had liver injury and the rest served as control. Causative drugs mainly included antipodagrics (xanthine oxidase inhibitors occupying 100% among antipodagrics), anticonvulsants (dibenzazepine occupying 76.92% among anticonvulsants), and traditional Chinese medicines. There was a statistically significant difference between the patients with liver injury and the control group in the history of liver disease, diabetes, and hyperlipidemia (P < 0.05). Nine of the 40 patients with liver injury died. High serum total bilirubin and creatinine levels were significantly associated with poor prognosis of DILI in patients with SJS/TEN (P < 0.05). Conclusion: DILI usually occurs in patients with SJS/TEN. Pre-existing liver disease, diabetes, and hyperlipidemia are independent risk factors for DILI in patients with SJS/TEN. High serum total bilirubin and creatinine levels may be useful prognostic markers for DILI in patients with SJS/TEN.

Background: There is a trend of increase in number of contact dermatitis cases. Studies on the prevalence and epidemiological pattern of allergic skin disorders in Indian scenario are not much available. The present study was designed to assess the epidemiological pattern of contact dermatitis in rural and urban areas in a peripheral district in eastern India. Aims and Objectives: This study was undertaken to find the prevalence of contact dermatitis and to assess the epidemiological pattern of contact dermatitis both in rural and urban community. Materials and Methods: The study was conducted in a medical college located at a semi-urban area in eastern India with written informed consent obtained from each participant. This hospital-based cross-sectional study was done from May 2017 to April 2018. Study population consisted of patients attending the dermatology OPD and having lesions clinically suggestive of contact dermatitis and there were 268 such patients. Patients attending the OPD were divided into urban and rural as per their address. Data analysis was done using suitable, standard, and appropriate statistical methods. Results: The prevalence of contact dermatitis was 4.38% among the dermatology OPD attendees. Urban prevalence was statistically significantly (P < 0.05) higher than rural prevalence. Contact dermatitis was common in the age group of 41–50 years. In urban areas, females were more affected than those in rural areas. Occupationally, the difference between urban and rural patients of contact dermatitis was statistically significant (P < 0.05). Cosmetic history in the urban group was significantly more (P < 0.05). Conclusions: Contact dermatitis prevalence and patient profile in certain factors showed a statistically significant difference between urban and rural patients.

Dowling–Degos disease (DDD) is a late-onset genodermatosis characterized by hyperpigmented macules on the flexures along with scattered comedo-like lesions and pitted acneiform scars. Follicular Dowling–Degos is a rare type of DDD, with only two reports so far. It presents with follicular papules and comedo-like lesions predominantly on the face and trunk. Dermoscopy of follicular DDD shows irregular star-shaped/Chinese letter pattern pigmentation along with comedo-like lesions. Herein, we describe diagnostic clues including dermoscopy in three patients of follicular DDD which can help in differentiating it from other disorders presenting with comedo-like lesions .

Crusted scabies is a rare and extremely contagious infestation by Sarcoptes scabiei. Kaposi's varicelliform eruption (KVE) refers to herpes simplex virus infection superimposed on pre-existing dermatosis such as atopic dermatitis, Darier's disease, and pemphigus. We report a case of KVE superimposed on crusted scabies in a middle-aged woman. Her condition was complicated with sepsis. She was treated with IV meropenem, vancomycin, and acyclovir and was released 2 weeks later in good condition. To our knowledge, only rare cases of crusted scabies complicated by KVE have been reported.

Secondary syphilis represents a diagnostic challenge due to its varied clinical manifestations. Co-infection with human immunodeficiency virus (HIV) adds to the diversity of the clinical presentation of syphilis. We herein report a case of secondary syphilis as an arthropod bite-like eruption in a previously undiagnosed HIV-coinfected patient. A 24-year-old homosexual male presented with multiple corticosteroid-resistant insect bite-like nodules on his trunk and bilateral arms. Skin biopsy disclosed plasma cell infiltration and positive Treponema pallidum staining. His symptoms got dramatic remission after benzathine penicillin G therapy. The presented case extends the clinical spectrum of secondary syphilis in HIV patient.

Background: A disease activity score obtained by using systemic lupus erythematosus disease activity index (SLEDAI) has traditionally been a reliable method to assess the SLE status of patients. More recently, a buccal micronucleus cytome assay (BMCA) has been developed for use as a biomarker of DNA damage in patients with SLE. There has been a very limited number of studies pertaining to the oral lesions in Arab population suffering from SLE in Asir region. Hence, it became utmost important to study epidemiological data of oral mucosal lesions in SLE patients. Distribution of oral lesions in SLE patients could also be helpful in better management of oral complications. Aim: The aim of this study was to determine the existence of a correlation between SLEDAI score and the degree of micronuclei (MN) formation using BMCA. Materials and Methods: After thorough oral examination of adult Saudi SLE patients of Asir hospital and that of healthy control subjects, the subjects underwent BMCA from normal unaffected bilateral buccal mucosae. Results: Pearson's correlation test showed that MN count did not significantly correlate with either disease activity or duration of SLE. Conclusions: Controlled state SLE does not lead to a significant increase in MN formation. Thus, the occurrence of premalignant lesions in the oral cavity could be minimized using proper management protocols.
