Background: Patch test is the gold standard for diagnosing allergic contact dermatitis. Conventionally, the patches are applied for 48 h, which in tropical weather conditions causes excessive sweating, leading to irritation, and sometimes the patches come off, making the test inconclusive.

Objective: To compare the patch test positivity after 24 and 48 h of occlusion time in patients of allergic contact dermatitis, using standard allergen concentration.

β-blocker therapy is currently the treatment of choice for infantile hemangiomas (IH), albeit with limited data on long-term treatment outcomes. Herein, authors treated 67 IH lesions in 47 patients with oral propranolol at 2 mg/kg/d for a median of 9 mo and followed them up for a median of 48 mo. While no maintenance therapy was required for 18 lesions (26.

While previous research has demonstrated that multiplex polymerase chain reaction (PCR) can be a cost-effective approach to detect various genes in crops, the availability of multiplex assays to simultaneously screen both grain quality and biotic stress resistance traits in rice () is limited. In this work, we report six novel multiplex assays that use a universal protocol to detect major rice grain quality (amylose content and fragrance) and biotic stress (blast, sheath blight, and bacterial leaf blight) traits with amplified products consisting of up to four primer pairs that can be analyzed using a standard agarose-based gel electrophoresis system. Recent studies have suggested that weedy rice has novel sources of disease resistance.

Objective: To develop a diagnostic algorithm for cystic fibrosis (CF) in the setting of unavailability of sweat chloride, based on clinical features and basic laboratory investigations.

Methods: In a prospective observational study, we enrolled children with recurrent/persistent pneumonia with either malabsorption or poor growth, undergoing a sweat chloride test, between January 2019 and December 2020. They were simultaneously evaluated for aquagenic wrinkling of hands, stool fat globules, sputum for bacterial culture, blood gas, and serum electrolytes.

The rhizosphere microbiome is a major determinant of plant health, which can interact with the host directly and indirectly to promote or suppress productivity. Oil palm is one of the world's most important crops, constituting over a third of global vegetable oil production. Currently there is little understanding of the oil palm microbiome and its contribution to plant health and productivity, with existing knowledge based almost entirely on culture dependent studies.

Acquired cutis laxa type II (Marshall syndrome) is a post-inflammatory elastolysis occurring in infancy and childhood. It is challenging to treat with very few effective treatment options available. Herein, we describe the case of a 3-month-old boy with acquired cutis laxa type II secondary to a neutrophilic dermatosis.

Background: Epidermolysis bullosa (EB) has profound effect on the subjective distress, family burden, and quality of life (QOL) of the primary caregivers (PCG). Knowledgeable PCG can efficiently manage children with these skin diseases and also improve their QOL.

Objectives: To assess the subjective distress, family burden, and QOL, to develop and assess the short-term effectiveness of a psycho-dermatological education package (PDEP) for the PCG of children with EB.

Background: There are few studies on basal cell carcinoma (BCC) from India. Long-term follow-up is available in only one study and the aesthetic outcome of treatment has not been evaluated in Indian patients.

Aims: In this retrospective study on BCC, we compared treatment failure, recurrence rates and aesthetic outcomes on long-term follow-up between surgical excision and repair, and nonsurgical and ablative treatments.

Background: No randomized studies compared the efficacy and safety of modified Kligman's triple combination (TC) with 1,064 nm Q-switched Nd-YAG laser (QSNYL) in melasma in darker skin.

Objectives: To compare the efficacy and safety of QSNYL and TC in the treatment of melasma in Fitzpatrick skin types IV and V.

Methods: In this split face randomized controlled trial, participants' cheeks were randomized to receive either weekly QSNYL (group A) or daily TC (group B) for 12 weeks, followed by 12 weeks of follow-up.

Article Synopsis
  • Vitiligo is a skin condition that causes loss of pigment, leading to white patches, and leukotrichia refers to the white hair associated with these patches; repigmentation of leukotrichia is essential for cosmetic improvement.
  • In a study of 20 patients with stable vitiligo and leukotrichia, two procedures were compared over a 9-month follow-up to assess the effectiveness of hair follicle cell suspension (HFCS) versus epidermal cell suspension (ECS) in promoting repigmentation.
  • The results showed that while ECS had a higher mean number of cells transplanted and slightly better repigmentation outcomes for both leukotrichia and vitiligo patches, the differences compared to HF

Tuberous sclerosis complex (TSC) is a multiorgan disorder characterized by formation of hamartomas and broad phenotypic spectrum including seizures, mental retardation, renal dysfunction, skin manifestations and brain tubers. It is inherited in an autosomal dominant pattern, caused due to mutation in either or genes. Seizures are one of the major presenting symptoms of TSC that helps in early diagnosis.

Background: Patch testing is the standard method to diagnose contact allergy. Patches are applied for 48 hours, which is inconvenient to patients in tropical weather. Therefore, we evaluated different patch test occlusion times with increased concentrations of an allergen to determine if occlusion time can be reduced without compromising patch test reactivity.

Background: Postacne scars have significant psychosocial distress among patients. Subcision is a well-known treatment modality specially for rolling type of acne scars, but is a crude mechanical process, which carries a risk of hematoma formation.

Aims: To compare the efficacy and safety of radiofrequency-assisted subcision (rSubcision) with conventional subcision in postacne scars.

The ridged skin of the palms and soles has several unique features: (i) presence of dermatoglyphics created by alternating ridges and grooves forming a unique pattern, (ii) presence of the highest density of eccrine sweat glands and absence of pilosebaceous units, and (iii) differential expression of keratins compared to the glabrous skin. These features explain the preferential localization of palmoplantar keratoderma (PPK) and several of its characteristic clinical features. PPK develops as a compensatory hyperproliferation of the epidermis and excessive production of stratum corneum in response to altered cornification of the palmoplantar skin due to mutations in the genes encoding several of the proteins involved in it.

Nanoemulsion formulation of vitamin D3 have been shown to have better bioavailability than the coarse emulsion preparation in vitro and in vivo animal studies. In the absence of randomised trial in humans, comparing the efficacy of nanotechnology-based miscellised vitamin D3 over conventional vitamin D3, we undertook this study. A total of 180 healthy adults were randomised to receive either micellised (DePura, group A) or conventional vitamin D3 (Calcirol, group B) at a monthly dose of 60 000 IU (1500μg) for 6 months.

In India, there is a lack of information about the adequate daily dose of vitamin D3 supplementation in school children. Hence, we undertook this study to evaluate the adequacy and efficacy of different doses of vitamin D3 in schoolchildren. A total of 1008 vitamin D-deficient (VDD) children, aged 6-16 years with serum 25-hydroxyvitamin D (25(OH)D) levels <50nmol/l, were cluster randomised into three groups (A-344, B-341 and C-232) for supplementation (600, 1000 and 2000 IU daily) of vitamin D3 under supervision for 6 months.

Recent advances in the field of genomics have seen the successful implementation of whole exome sequencing as a rapid and efficient diagnostic strategy in several genodermatoses. The aim of this study was to explore the potential of molecular studies in dystrophic epidermolysis bullosa (DEB) in India. Whole exome sequencing was performed using genomic DNA from each case of epidermolysis bullosa, followed by massively parallel sequencing.
