Mapping the TYR gene reveals novel and previously reported variants in Eastern Indian patients highlighting preponderance of the same changes in multiple unrelated ethnicities.

Oculocutaneous albinism (OCA) is a group of congenital autosomal recessive disorders with seven known subtypes (OCA1-OCA7) characterized by loss or absence of pigmentation in the skin, hair, and eyes. OCA1, caused by pathogenic variations in the tyrosinase (TYR) gene, has been documented to be the most prevalent subtype across the world including India. In the present study, we recruited 53 OCA-affected individuals from 45 unrelated families belonging to 20 different marriage groups/ethnicities of 15 different districts of West Bengal.

Blaschkoid lichen planus occurring in childhood systemic lupus erythematosus.

Lupus erythematosus-lichen planus (LE-LP) overlap syndrome represents a rare disorder with clinical and histopathological features of both lichen planus and lupus erythematosus presenting in the same lesions. However, lichen planus and lupus erythematosus can also coexist in the same patient. Blaschkoid lichen planus in the setting of concurrent childhood-onset systemic lupus erythematosus has not been previously described.

A Quality of Life Study of Patients with Leprosy Attending the Dermatology OPD of a Tertiary Care Center of Eastern India.

Background: Leprosy is a chronic infectious disease caused by affecting the skin, peripheral nervous system, and other tissues. The disease is associated with social stigma, and the patients sometimes suffer social discrimination because it often leads to visible physical deformities. Hence, leprosy may have severe impact on the quality of life (QoL) of patients.

Adolescent cannabis exposure increases heroin reinforcement in rats genetically vulnerable to addiction.

On the basis of epidemiological studies it has been proposed that cannabis use plays a causal role in the abuse of highly addictive drugs (Gateway Hypothesis). However, epidemiological studies are intrinsically unable to provide evidence of causality. Experimental studies can provide this evidence but they are feasible only in animal models and to date such evidence is lacking.

One-month follow up of a randomized clinical trial-phase II study in 6 to <24 months old Indonesian subjects: Safety and immunogenicity of Vi-DT Typhoid Conjugate Vaccine.

Introduction: World Health Organization estimates the annual global incidence of typhoid fever at 11-21 million cases and approximately 128 000 to 161 000 deaths. The currently used Vi-polysaccharides (Vi-PS) vaccines have been proven to be safe and efficacious in children 2 years and above. However, poor immunogenicity of Vi-PS was observed in children below 2 years of age.

Effectiveness and safety of autologous platelet-rich plasma therapy with total contact casting versus total contact casting alone in treatment of trophic ulcer in leprosy: An observer-blind, randomized controlled trial.

Background: Trophic ulcers secondary to leprosy pose a great stigma to patients and remain a challenge to the treating dermatologists. Platelet-rich plasma (PRP) introduces growth factors directly into the wound and aids in rapid healing. The role of PRP in the treatment of trophic ulcers in leprosy patients has not yet been established by randomized controlled trials.

First and second order topological phases on ferromagnetic breathing kagome lattice.

In this work, topological properties of a ferromagnetic Heisenberg model on a breathing kagome lattice are investigated extensively in the presence of Dzyaloshinskii-Moriya interaction. While the kagome ferromagnet hosts only a single first order topological phase, the breathing kagome system exhibits multiple first and second order topological phases along with their coexistence. Magnon dispersion relation is obtained by using linear spin wave theory.

Lights and shadows of schizophrenia therapy research: Lessons from oral risperidone and olanzapine.

Background: Recently, patents of several atypical antipsychotics have reached their expiration date.

Aims: The purpose of the study was to highlight whether modifications of economic/scientific factors may be associated with possible changes in ongoing clinical research on antipsychotic drugs.

Methods: A large systematic analysis was used to depict the time-dependent distribution of published research articles addressing the clinical properties of oral risperidone and olanzapine conventional tablets, two largely prescribed atypical antipsychotics for which the patents have already expired in most of the countries.

Prevalence and causes of avoidable blindness and visual impairment, including the prevalence of diabetic retinopathy in Siwan district of Bihar, India: A population-based survey.

Purpose: The aim of this study was to estimate the prevalence and causes of visual impairment (VI) and blindness and diabetic retinopathy (DR) in Siwan district, Bihar.

Methods: A population-based cross-sectional study was done from January to March 2016 using the Rapid Assessment of Avoidable Blindness 6 (RAAB 6, incorporating DR module) methodology. All individuals aged ≥50 years were examined in 57 randomly selected clusters within the district.

Primary eye care in India - The vision center model.

The World Health Organization (WHO) Global Action Plan (GAP) 2014-19 emphasize providing Comprehensive Eye Care (CEC) using the health system approach to achieve Universal Eye Health Coverage (UEHC). An important aspect of CEC is Primary Eye Care (PEC). The scope of PEC varies significantly with primary health workers providing PEC in most parts of the developing world, whereas in developed nations PEC is provided by specialized personnel such as optometrists.
