A Systematic Review of Risk Factors for Hepatitis C Virus Infection Among Low-Risk Population in India.

Background: Identification of risk factors for hepatitis C virus (HCV) transmission will help in targeted screening of people who are at risk for HCV. Method: Indian studies, published between January 1989 and June 2020, were systematically reviewed to identify the relevant studies. We searched electronic databases including PubMed/Medline, Embase, Scopus, and Google scholar to identify the original data published in English language. The full-text studies, published in any form, which reported data on risk factors for HCV transmission among low-risk population were selected. The studies which exclusively included high-risk groups were excluded. Results: Data were extracted from 31,176 participants included in 25 studies (median [range] 40 [7-20,113). The participants were HCV infected patients who visited the hospital (n = 10), community population (n = 6), pregnant women (n = 5), blood donors (n = 2), people with diabetes mellitus (n = 1), army recruits (n = 1), or slum dwellers (n = 1). These studies provided data on blood transfusion, use of unsafe injections, minor or major surgery, unsafe dental procedures, tattooing, body piercing, obstetrical procedures, unsafe shaving, intravenous drug use, and unsafe sexual practices as risk factors for HCV transmission. Conclusion: Unsafe injections, body piercing, unsafe dental procedure, unsafe shaving, and tattooing were identified as major risk factors for reported by HCV population participants.More data are needed to identify the risk factors for HCV in Indian population. Risk-factor-targeted screening may increase the yield and reduce the cost of HCV screening in India.

Electrodiagnostic Assessment of Plexopathies.

Disorders of the brachial and lumbosacral plexus are complex and may occur as a consequence of trauma, compression, inflammatory disorders, malignant infiltration, or delayed effects of radiation therapy. An understanding of plexus anatomy and surrounding structures will allow the electromyographer to facilitate an efficient and comprehensive assessment of the plexus. A careful and thorough electrodiagnostic assessment allows for localization within the plexus and may provide important information about underlying pathology and prognosis.

Autoimmune thyroid disease in patients with vitiligo: prevalence study in India.

OBJECTIVE: To identify the prevalence of autoimmune thyroid disease (AITD) in Asian Indian patients with vitiligo and to compare the clinical profile between thyroid peroxidase (TPO) antibody-positive and TPO antibody-negative groups. METHODS: In this cross-sectional, case-controlled study, 50 patients with vitiligo (29 women and 21 men) were included. Patients with previous disorders, irradiation, or surgical procedures involving the thyroid were excluded from the study. All participants underwent a complete physical examination, and a single fasting blood sample was analyzed for thyroid function (triiodothyronine, thyroxine, thyroid-stimulating hormone, and TPO and thyroglobulin antibodies), inflammatory and immunologic markers (erythrocyte sedimentation rate, C-reactive protein, and rheumatoid factor), and serum calcium, phosphorus, and alkaline phosphatase concentrations. All patients underwent thyroid ultrasonography, and the data were analyzed by appropriate statistical methods. RESULTS: The mean age of the study participants was 42.7 ± 17 years, and 14 of 50 patients (28%) had TPO antibody positivity. A goiter was present in 11 of 50 patients, and the thyroid volume by ultrasonography was similar between the 2 groups. Subclinical hypothyroidism was found in 14 of 50 patients (28%) but more frequently in the TPO antibody-positive group (8 of 14 or 57%) than in the TPO antibody-negative group (6 of 36 or 17%). The prevalence of AITD was 20 of 50 patients (40%) when the TPO antibody-positive group and those with subclinical hypothyroidism were considered collectively. None of the patients had overt hypothyroidism or hyperthyroidism. All other clinical, biochemical, and inflammatory variables did not differ significantly between the TPO antibody-positive and antibody-negative groups. CONCLUSION: Our data showed a 40% prevalence of thyroid disease in patients with vitiligo in India. The risk is exacerbated in patients with thyroid autoimmunity; thus, regular screening of patients with vitiligo for AITD is needed.

Diabetes in young--unusual case presentation.

Diabetes in young is increasing in prevalence with each decade. Phenotypic features like obesity and acanthosis nigricans characterize type 2 diabetes, whereas autoimmune diseases like vitiligo and hypothyroidism suggest type 1 diabetes. We recently encountered a young boy with vitiligo who presented with hyperglycemia, but not associated with ketonuria and has underlying chronic pancreatitis with secondary diabetes. We report the case for its unusual presentation and etiology of the diabetes.
