ABSTRACT
Aims:To determine the incidence of renal scarring among patients with primary vesicoureteral reflux (VUR) and the possible risk factor(s), we studied 69 children (42 girls and 27boys) with VUR attending the Pediatric opd.Study Design:Prospective Observational study.Place and duration of Study:Department of pediatrics,Sher I Kashmir Institute of Medical Sciences,Srinagar, Kashmir between June 2017 to June 2018.Methodology:All the patients were assessed for VUR grade by voiding cystoureterography and for presence of renal scarring by (99 m) technetium dimercapto–succinic acid scintigraphy. Results:Grade of reflux and number of urinary tract infection (UTI) episodes (≥3) were found to be statistically significant risk factors for renal scarring (P <0.05). However,there was no significant association with gender,familial history and laterality of the disease (P >0.05). Similarly, there was no statistically significant difference of frequency of renal scarring among the different age groups (P >0.05).Conclusions:It was concluded that recurrences of UTI and VUR severity are significant risk factors for renal scarring in children with VUR. Therefore,identification of VUR at an early age may offer the opportunity to prevent episodes of UTI and possible formation of renal scars that may result in end-stage renal failure
ABSTRACT
Introduction: mercury is a heavy metal widely dispersed in nature, occurring in three chemical forms. Exposure to mercury at work sites and even at home may be clinically significant. Objective: to update the knowledge about the risks of this toxic element. Case report: the case of a teenager and his family poisoned by elemental mercury is reported. The diagnostic process was difficult, mainly due to an initial presumption of probable infectious etiology, unavailability of key anamnestic data and unusual clinical behavior, with signs and symptoms of multisystem compromise (neurological, hepatic, renal and dermatological compromise). Discussion: the study was based on literature review of various clinical presentations regarding this poisoning and its management, emphasizing the need for dimercaptosuccinic acid chelator. As a major public health problem, the importance of education and implementation of public policies to have a mercury-free environment is discussed.
Introducción: el mercurio es un metal pesado ampliamente distribuido en el medio ambiente, en sus tres formas químicas. La exposición a dicho metal en recintos laborales e incluso en el hogar, puede llegar a ser clínicamente significativa. Objetivo: actualizar el conocimiento acerca de los riesgos de este tóxico. Caso clínico: se presenta el caso clínico de un adolescente y su familia intoxicados por mercurio elemental, cuyo proceso diagnóstico fue difícil, principalmente por la presunción inicial de una probable etiología infecciosa, falta de disponibilidad de datos anamnésticos claves y el inusual comportamiento clínico, con signos y síntomas de compromiso multisistémico (neurológico, hepático, renal y dermatológico). Discusión: se revisa la literatura en relación a las diversas formas de presentación clínica de esta intoxicación y su manejo, destacando la utilidad del quelante ácido dimercaptosuccínico. Por ser un importante problema de salud pública, se destaca la trascendencia de la educación e implementación de políticas públicas por un ambiente libre de mercurio.
