Vitamin A deficiency (VAD) has been recognized as a public-health issue in developing countries. Economic constraints, sociocultural limitations, insufficient dietary intake, and poor absorption leading to depleted vitamin A stores in the body have been regarded as potential determinants of the prevalence of VAD in South Asian developing countries. VAD is exacerbated by lack of education, poor ...

OBJECTIVE To determine if vitamin A supplementation is associated with reductions in mortality and morbidity in children aged 6 months to 5 years. DESIGN Systematic review and meta-analysis. Two reviewers independently assessed studies for inclusion. Data were double extracted; discrepancies were resolved by discussion. Meta-analyses were performed for mortality, illness, vision, and side eff...

BACKGROUND The objective was to evaluate concordance between 2002 American-European Consensus Group (AECG) and 2016 American College of Rheumatology (ACR)/European League Against Rheumatism (EULAR) classification criteria for primary Sjögren's syndrome (pSS) and to assess how salivary gland ultrasonography (SGUS) might improve the classification of patients. METHODS Patients with suspected pS...

Forty three patients with cystic fibrosis, aged 8-44 years (median 16 years), were examined for evidence of vitamin A deficiency. Eight patients had abnormal dark adaptation tests and three had conjunctival xerosis. Serum vitamin A and retinol binding protein concentrations were significantly lower in the affected patients who were also more likely to have abnormal liver function tests. Five pa...

The study analyzed data from a systematic sample of children, aged less than five years, who presented with persistent diarrhoea (diarrhoea of more than 14 days duration). It aims to differentiate (a) non-severe persistent diarrhoea (with no or mild dehydration) and (b) severe persistent diarrhoea (with moderate or severe dehydration), and to identify individual characteristics associated with ...

The impact on vitamin A deficiency (VAD), wasting malnutrition, and excessive childhood mortality of two alternative approaches-nutrition education and mega-dose capsule distribution (6-12-month-olds: 100,000 IU; 1-5-year-olds: 200,000 IU)-in communities in Nepal are compared. Approximately 40,000 children from 75 locations in seven districts in two ecological settings (lowland and hills) took ...

The importance of vitamin A for the normal development and maintenance of skeletal, nervous and epithelial tissues has long been recognized, and the general signs of deficiency of this vitamin in chickens have been described by Seifried (1930) and by Beach (1923). One of the most important changes caused by vitamin A deficiency, often leading to serious infection, is the replacement of many sec...

Background Recently, compelling data have been published on the value of salivary gland ultrasound (SGUS) in differentiating between primary Sjögren’s Syndrome (SS) from nonimmune-mediated sicca syndrome. Limited are available regarding diagnostic accuracy SGUS to distinguish SS undifferentiated connective tissue diseases associated with Objectives The aim this study was evaluate power patients...

The aim of the study was to analyze mortality patients infected with hepatitis C virus (HCV) and co-infected human immunodeficiency (HIV) extrahepatic manifestations associated cryoglobulinemia, assess dependence risk fatal outcome on such predictors as presence HIV infection, cirrhotic liver transformation, antiviral therapy (AVT) chronic C, cryoglobulin levels.

MALNUTRITION as a cause of blindness has been and still is, much underestimated. In many countries it is the chief cause of blindness in young children. The onset is insidious and difficult to diagnose and the later stages proceed rapidly to irreversible damage. Opthalmologists have tended not to be particularly interested in conditions that do not make demands on their diagnostic or surgical s...
