Seguimiento de dilatación del tracto urinario neonatal diagnosticada en la evaluación de infección del tracto urinario / Follow-up of Neonatal Urinary Tract Dilatation Diagnosed in the Evaluation of Urinary Tract Infection

Objetivo: Mostrar las características y seguimiento de la dilatación del tracto urinario en recién nacidos con infección del tracto urinario. Métodos: Estudio observacional, descriptivo, realizado desde 1992 hasta 2019, en neonatos ingresados con infección del tracto urinario. A todos se les realizó ultrasonido renal y uretrocistografía miccional. Se analizaron las características clínicas y de radioimagen de presentación en el seguimiento de la dilatación del tracto urinario. Resultados: Se estudiaron 403 pacientes. La mediana de seguimiento fue de 13 meses. El ultrasonido renal resultó positivo para dilatación del tracto urinario en 148 (36,7 por ciento). Predominaron los grados de dilatación ligera (5-10 mm.) sobre grados moderados y severos. En 38 casos (9,4 por ciento) la dilatación del tracto urinario se asoció a reflujo vésico-ureteral. La condición más común fue la dilatación transitoria con una mediana de desaparición de la dilatación 5 meses. Hubo asociación estadística significativa de la desaparición de la dilatación del tracto urinario con el grado de esta y entre aquellos casos calificados de transitoria con los otros portadores de alguna anomalía del tracto urinario que también tuvieron desaparición de la dilatación en algún momento de su evolución. Conclusiones: Cerca de una tercera parte de los neonatos con infección del tracto urinario tuvieron dilatación del tracto urinario en ultrasonido renal, con predominio de grado ligero, como probable expresión de una anomalía del tracto urinario subyacente. Con frecuencia ocurre resolución de la dilatación del tracto urinario en aquellos casos no asociados con anomalía del tracto urinario, habitualmente dentro del primer año de vida(AU)

OBjective: To show the characteristics and follow-up of urinary tract dilatation in neonates with urinary tract infection. Methods: Observational, descriptive study performed from 1992 to 2019, in neonates admitted with urinary tract infection. All underwent renal ultrasound and voiding urethrocystography. The clinical and radioimaging features of presentation were analyzed in the follow-up of urinary tract dilatation, Results: 403 patients were studied. The median follow-up was 13 months. Renal ultrasound was positive for urinary tract dilatation in 148 (36.7 percent). Mild degrees of dilatation (5-10 mm) predominated over moderate and severe degrees. In 38 cases (9.4 percent) urinary tract dilatation was associated with vesico-ureteral reflux. The most common condition was transient dilatation with a median disappearance of dilatation 5 months. There was significant statistical association of the disappearance of urinary tract dilatation with the degree of dilatation and between those cases qualified as transient with the other carriers of some urinary tract anomaly who also had disappearance of dilatation at some point in their evolution. Conclusions: About one third of neonates with urinary tract infection had dilatation of the urinary tract on renal ultrasound, predominantly of mild degree, probably expression of an underlying anomaly. Resolution of dilatation frequently occurs in those cases not associated with urinary tract anomaly, usually within the first year of life(AU)

Effectiveness of Slow Breathing on Blood Pressure and Quality of Life in Patients with Hypertension: A Randomized Trial

Background: Hypertension constitutes a significant cardiovascular burden globally. Non-pharmacological interventions arehighly sought either as an adjunct or primary means of managing hypertension. Slow breathing (SB) is one of such approachwhich gains attention in recent times due to its multiple physiological benefits in lowering blood pressure (BP). However, thereis a gap in literature testing the ability of SB training on quality of life (QOL) of hypertensive (HT) patients.Aim of the Study: This study aims to find out the effectiveness of SB on reduction of BP and improvement in the health-relatedQOL in HT patients.Materials and Methods: It was a randomized, open, and parallel-group trial design carried out at the Outpatient Departmentof Medicine in Rajah Muthiah Medical College and Hospital, Annamalai University, Chidambaram, Tamil Nadu, India. The studyconsists of 60 HT patients assigned equally to either study or control group. The study group was trained with SB training for4 weeks, whereas no specific treatment was given for controls.Results: The mean drop in systolic BP (SBP) for the study group was 14.24 ± 3.30 mmHg, whereas the mean drop was only5.28 ± 2.26 mmHg for controls. The mean drop in diastolic BP (DBP) was 6.20 ± 2.69 mmHg for the study group, whereasit was only 3.12 ± 2.05 mmHg for controls. There was significantly higher drop in systolic as well as DBP in the study group.Likewise, the World Health Organization QOL-BREF (WHOQOL-BREF) was improved to 10.79 ± 5.47 in the 0–100 scale forthe study group, whereas the mean improvement in the WHOQOL-BREF for control was 5.95 ± 0.01 in the 0–100 point scale.Conclusions: It was concluded that 4 weeks of SB training were effective in reducing BP and improving QOL in patients with HT.

Correlación entre el diagnóstico ecográfico prenatal y posnatal en casos de hidronefrosis fetal / Correlation between prenatal and postnatal ultrasound diagnosis of fetal hydronephrosis

Introduction: Prenatal ultrasound detects fetal anomalies in 1% of pregnancies, about 20-30% of them are urogenital and among them 50% are fetal urinary tract dilatations (UTD). Objective: To establish the correlation between prenatal and postnatal hydronephrosis diagnosis, as well as to analyze the prognosis. Design, patients, interventions and main outcome measure: Retrospective observational study performed by the Prenatal Diagnosis Unit of Parc Taulí Hospital (Sabadell), which included 177 pregnant women with ultrasound diagnosis of UTD between January 2011 and December 2016. We performed a descriptive analysis of the most important ultrasound and perinatal variables. The main outcome measure was the degree of dilatation of UTD. Results: The prevalence of HNF was 1.17%; 82.8% were diagnosed in the second trimester ultrasound; 42.9% of fetal hydronephrosis cases were bilateral and, in 95.6%, the urogenital pathology was not associated with other malformations. Congenital heart disease was the most frequently associated prenatal anomaly (3.3%). Among 93 low-risk hydronephrosis cases diagnosed in the second trimester, 53.8% resolved spontaneously in the third trimester, 30.1% remained stable and 16.1% worsened. Of the 32 cases of moderate-severe UTD diagnosed in the second trimester, only 9.4% improved in the third trimester. Complementary examination was required in 46.9% of the neonates and 14.1% required surgical intervention. Conclusions: Most cases of fetal hydronephrosis were diagnosed by second trimester ultrasound. Mild UTD presents good prognosis as opposed to moderate-severe cases, which usually persist after birth.

Introducción. La ecografía prenatal permite detectar una anomalía significativa en 1% de los embarazos; de ellos, 20 a 30% son genitourinarias y 50% de estas son hidronefrosis fetales (HNF). Objetivo. Establecer una correlación entre el grado de hidronefrosis prenatal y posnatal, así como analizar las implicaciones pronósticas. Diseño, pacientes, intervenciones y variables principales. Estudio observacional retrospectivo realizado por la Unidad de Diagnóstico Prenatal del hospital Parc Taulí de Sabadell, que incluyó un total de 177 gestantes con diagnóstico ecográfico de HNF entre enero de 2011 y diciembre de 2016. Se realizó un análisis descriptivo de las variables ecográficas y perinatales más importantes. La principal variable de estudio fue el grado de dilatación de la HNF. Resultados. La prevalencia de HNF fue 1,17%. El 82,8% de los casos fue diagnosticado en la ecografía del 2º trimestre. En 42,9%, la afectación fue bilateral, y en 95,6% la malformación renal fue aislada. La cardiopatía fue la anomalía congénita asociada con más frecuencia (3,3%). De las 93 hidronefrosis de riesgo bajo diagnosticadas en el 2º trimestre, 53,8% se normalizaron en el 3er trimestre, 30,1% permanecieron estables y 16,1% progresaron. De los 32 casos de HNF moderadas-severas diagnosticadas en el 2º trimestre, solo 9,4% se normalizaron en el 3er trimestre. El 46,9% de los neonatos precisó exploraciones complementarias y 14,1% intervención quirúrgica. Conclusiones. Existe buena correlación de la HNF prenatal y posnatal. La HNF leve presenta buen pronóstico, mientras que la moderada-severa suele persistir posnatalmente.

Clinical features of diabetes insipidus with urinary tract dilatation / 中华内分泌代谢杂志

Diabetes insipidus ( DI) could lead to urinary tract dilatation, even renal dysfunction. This study compared clinical features of DI with or without urinary tract dilatation. The results showed that the former had earlier onset age, more male patients, longer duration, and higher serum creatinine, as well as lower urine osmotic pressure and urine specific gravity after injection of vasopressin. But only disease duration was the independent risk factor (OR=1. 248). More nephrogenic DI and more hereditary DI were with urinary tract dilatation compared with central DI or acquired DI.

Conducta médica posnatal ante la dilatación del tracto urinario superior fetal / Postnatal medical behavior in face a dilatation of fetal high urinary tract

El seguimiento sistemático del embarazo normal mediante el estudio ultrasonográfico materno-fetal ha demostrado que por cada 500 embarazos debemos esperar una anomalía importante del tracto urinario. La anomalía detectada con mayor frecuencia es la dilatación del tracto urinario superior, que si bien la mayoría de las veces no se traduce en una alteración importante, obliga a su estudio posnatal para poder valorar su significación. Una dilatación del tracto urinario superior puede ser la traducción de una hidronefrosis obstructiva por estenosis ureteropiélica, una hidronefrosis no obstructiva, un reflujo vesicoureteral o una pielectasia, y menos frecuentemente, puede ser la imagen de un doble sistema excretor con el superior obstruido, un megauréter obstructivo o no obstructivo, o una valva de uretra posterior en el sexo masculino. En esta revisión se presentan los criterios diagnósticos y el tratamiento clínico de las hidronefrosis y pielectasias, así como el estudio de los casos en que se sospecha reflujo vesicoureteral, y se relatan las anomalías encontradas en 318 niños en que el ultrasonido materno-fetal detectó alguna alteración del tracto urinario. Aunque no tan frecuente como las pielectasias y las hidronefrosis no obstructivas, las estenosis pieloureterales que producen obstrucción, pueden traer serias consecuencias sobre la función renal, que obligan a tomar decisiones médicas, y, en ocasiones, quirúrgicas, para mejorar la calidad de vida de estos niños.

The systematic follow-up of the normal pregnancy by means of a mother-fetus ultrasonography study has demonstrated that for each 500 pregnancies, we must to expect a significant anomaly of urinary tract. The more frequent anomaly detected is the high urinary tract dilatation, which if not always it is a significant alteration, leads to a postnatal study to assess its significance. A high urinary tract dilatation may to give rise to an obstructive hydronephrosis due to ureteropyelitis anastomosis; a non-obstructive hydronephrosis, a vesicoureteral reflux or a pyelectasia and less frequently may be an image of double excretory system with the superior one obstructed, an obstructive or not megaureter, or a valve or the posterior urethra in male sex. In present review are showed the diagnostic criteria and the clinical treatment of the hydronephrosis and the pyelectasia, as well as the study cases with suspicion of vesicoureteral reflux mentioning the anomalies founded in 318 children in whom the mother-fetus ultrasound detected some alteration of the urinary tract. Although not so frequent as the non-obstructive pyelectasia and the hydronephrosis, the pyeloureteral stenosis producing obstruction, may give rise to serious consequences on the renal function leading to make a medical decision, and occasionally, of surgical type to improve the quality of life of these children.
