WAGRO syndrome: a rare genetic condition associated with aniridia and additional ophthalmologic abnormalities

ABSTRACT Aniridia is a congenital eye disorder with a variable degree of hypoplasia or absence of iris tissue. It is caused by loss of function of the PAX6 gene and may be an isolated ocular abnormality or part of a syndrome. WAGRO refers to a rare genetic condition leading to Wilms tumor, aniridia, genitourinary anomalies, mental retardation, and obesity and is caused by a deletion of the short arm of chromosome 11 (11p), where the PAX6 gene is located. Here, we report on an 8-year-old boy with aniridia, polar cataract, and lens subluxation along with neuropsychomotor and speech delays. Karyotype evaluation showed an interstitial deletion including region 11p13-p14, confirming the diagnosis of WAGRO syndrome. In cases of aniridia, a diagnosis of WAGRO syndrome should be considered.RESUMO A aniridia é uma doença ocular congênita com grau variável de hipoplasia ou ausência do tecido da íris.

AbstractFat-mass and obesity-associated protein (Fto) plays important roles in energy metabolism. It also acts as a demethylase and is most abundantly found in the brain. In the present study, we examined the spatial and temporal changes of Fto immunoreactivity after five minutes of transient forebrain ischemia in the hippocampus. In the control group, Fto immunoreactivity was mainly observed in the nucleus of pyramidal cells in the CA1 and CA3 regions as well as the polymorphic layer, granule cell layer, and subgranular zone of the dentate gyrus. Fto immunoreactivity was transiently, but not significantly, increased in th...

Conclusion: There was a high prevalence of MetS and abnormal ECG among the studied population. Abnormal ECG findings were more common in men with no differential association in people with or without MetS. However, a significant association existed between certain components of MetS and ECG abnormalities in men only. Male gender and HDLc were independent predictors of ECG Abnormalities.Keyword: Electrocardiography, metabolic syndrome, africans.

Introduction: Hypertension is a cause and consequence of chronic kidney disease globally. The other factors that work in concert with hypertension to cause CKD are yet to be clearly elucidated. Studies have identified proteinuria, dyslipidemia, obesity, smoking and family history of CKD as renal risk factors. Due to the high morbidity and mortality associated with occurrence of CKD including the enormous financial burden involved in its management, the knowledge of prevention and understanding of the risk factors for development of CKD is highly essential. Therefore, Identifying well defined risk factors that display stron...

In this study, we examined 1,182 subjects (658 men and 524 women, 62.3 ± 11.7 years on average) who underwent voluntary health check-ups and sought to determine the optimal cut-off value of WC for predicting carotid IMT thickness. Receiver operating characteristic curve analysis of WC was utilized to predict high carotid IMT (defined as carotid IMT ≥ 1.1 mm). We determined that the appropriate WC cut-off value was a WC ≥ 79 cm for men and women. There was a statistically significant difference in the prevalence of high carotid IMT between WC ≥ 79 cm and WC

Authors: Wu CC, Chang CS, Hsu CC, Wang CP, Tsai IT, Lu YC, Houng JY, Chang CC, Chung FM, Lee YJ, Hung WC Abstract Low-circulating levels of adiponectin (ADPN) are associated with obesity, diabetes mellitus, and coronary artery disease. On the contrary, some studies have demonstrated a link between relatively high levels of plasma ADPN and heart failure, atrial fibrillation, and adverse outcome. However, little is known about the relationship between ADPN level and prolonged QT interval. The aim of this study was to investigate the association between plasma ADPN levels and prolonged QT interval in patients with sta...
