Because transethnic analysis may facilitate prioritization of causal genetic variants, we performed a genomewide association study (GWAS) of psoriasis in South Asians (SAS), consisting of 2,590 cases and 1,720 controls. Comparison with our existing European-origin (EUR) GWAS showed that effect sizes of known psoriasis signals were highly correlated in SAS and EUR (Spearman ρ = 0.78; < 2 × 10).

Objective: To evaluate the effect of platelet-rich plasma on hair regrowth and lesional T-cell cytokine expression in alopecia areata.
Methods: This was a randomized, placebo-controlled, split-head study involving 27 patients with alopecia areata (Severity of Alopecia Tool score ≥25%).
Background: In the absence of a standard protocol, several methods and devices have been used for preparing platelet-rich plasma (PRP) with varying platelet concentrations.
Methods: Venous blood sample from 20 patients was used for preparing PRP using two methods: a manual double-spin method (1 spin at 160 g × 10 min, 2 spin at 400 g × 10 min), and using a commercially available automated device (DrPRP-Kit®, REMI Laboratory Instruments). Platelet, erythrocyte, and total leukocyte counts were calculated for each PRP sample and compared.
The persistent discoloration in lichen planus pigmentosus (LPP) is secondary to persistent melanophages in the superficial dermis in these patients. We evaluated the effect of Q-switched Nd-YAG laser on the clinical, pigmentary, and immunological markers in patients with LPP. Nine females with a clinical diagnosis of LPP were included in the study.

Platelet-rich plasma (PRP) has growth factors which may stimulate melanocyte migration and proliferation of keratinocytes and fibroblasts. The objective of this study was to compare the extent of repigmentation achieved by transplantation of NCES suspended in PRP with that of NCES suspended in phosphate buffered saline (PBS).

Factor VIII (FVIII) inhibitors are generally time and temperature dependent whereas LAs are immediate acting inhibitors (IAIs). The present study reports the challenges in laboratory detection of both progressive and non-progressive, specific FVIII inhibitors in the presence of LA.

Aim: To assess the use of a novel technique, autologous non-cultured dermal cell suspension transplantation, for correction of localized facial volume loss due to inflammatory pathologies.
Vitiligo is a depigmentary disease where melanocytes of the basal layer of epidermis are selectively destroyed by immune-cell-mediated cytotoxicity. The T cell immunoglobulin- and mucin-domain-containing molecules (TIMs) are involved in immune regulation, and their participation is not known in vitiligo. The present study revealed significant increase in the percentage of CD3+CD4+TIM3+ T cells (P < 0.

A serious complication of replacement therapy in patients with bleeding disorders is the development of 'inhibitors', particularly FVIII inhibitors in haemophilia A patients. This leads to an increase in the management cost, morbidity and mortality, especially post-operatively. The mechanism of FVIII inhibitor development is quite complex and it is difficult to predict inhibitor development, but a prompt and accurate diagnosis is critical as early therapy can save lives.
