Association of Maternal Iodine Status With Child IQ: A Meta-Analysis of Individual Participant Data

2019

Abstract Context Although the consequences of severe iodine deficiency are beyond doubt, the effects of mild to moderate iodine deficiency in pregnancy on child neurodevelopment are less well established. Objective To study the association between maternal iodine status during pregnancy and child IQ and identify vulnerable time windows of exposure to suboptimal iodine availability. Design Meta-analysis of individual participant data from three prospective population-based birth cohorts: Generation R (Netherlands), INMA (Spain), and ALSPAC (United Kingdom); pregnant women were enrolled between 2002 and 2006, 2003 and 2008, and 1990 and 1992, respectively. Setting General community. Participa…

Outcomes after perioperative SARS-CoV-2 infection in patients with proximal femoral fractures: an international cohort study

2021

ObjectivesStudies have demonstrated high rates of mortality in people with proximal femoral fracture and SARS-CoV-2, but there is limited published data on the factors that influence mortality for clinicians to make informed treatment decisions. This study aims to report the 30-day mortality associated with perioperative infection of patients undergoing surgery for proximal femoral fractures and to examine the factors that influence mortality in a multivariate analysis.SettingProspective, international, multicentre, observational cohort study.ParticipantsPatients undergoing any operation for a proximal femoral fracture from 1 February to 30 April 2020 and with perioperative SARS-CoV-2 infec…

Outcomes After Vascular Surgery Procedures in Patients with COVID-19 Infection: A National Multicenter Cohort Study (COVID-VAS)

2021

Objectives To analyze the outcome of vascular procedures performed in patients with COVID-19 infection during the 2020 pandemic. Methods This is a multicenter, prospective observational cohort study. We analyzed data from 75 patients with COVID-19 infection undergoing vascular surgery procedures in 17 hospitals across Spain and Andorra between March and May 2020. The primary end point was 30-day mortality. Clinical Trials registry number NCT04333693. Results The mean age was 70.9 (45–94) and 58 (77.0%) patients were male. Around 70.7% had postoperative complications, 36.0% of patients experienced respiratory failure, 22.7% acute renal failure, and 22.7% acute respiratory distress syndrome (…

Postoperative intussusception in childhood

1998

Over a period of 10 years, five children developed postoperative intussusception after intra-abdominal procedures at the Department of Pediatric Surgery of the Johannes Gutenberg University Mainz. Two appendectomies, one ileal resection for a Meckel's diverticulum, one operative procedure for Hirschsprung's disease plus intestinal neuronal dysplasia type B, and one hiatoplasty with jejunostomy preceded the intussusception. Three of the five children were older than 2 years. The clinical symptoms consisted primarily of abdominal distension, diffuse abdominal pain, bilious vomiting, and rectal bleeding in one case. Preoperative diagnosis was achieved in four cases by abdominal ultrasound. Pla…

Vesicoureteral reflux in young patients: Comparison of voiding color Doppler US with echo enhancement versus voiding cystourethrography for diagnosis…

2004

We assessed the accuracy of voiding color Doppler ultrasonography (US) with echo enhancement for diagnosis or exclusion of vesicoureteral reflux (VUR) versus voiding cystourethrography (VCUG) and evaluated patient tolerance of the echo-enhancing agent. One hundred twenty-two patients (ages range, 1 month to 17 years) with 244 ureterorenal units underwent voiding color Doppler US with echo enhancement, which was followed by VCUG on the same day. After US of the urinary tract, the bladder was filled with saline solution via catheter. Then an echo-enhancing agent was instilled, and color Doppler US was performed. Reflux was diagnosed when microbubbles appeared in the ureter or the pelvicalicea…

Ureterosigmoidostomy: an outdated approach to bladder exstrophy?

1990

Long-term results among 46 children with ureterosigmoidostomy are presented. The indication for ureterosigmoidostomy had been bladder exstrophy in 40 patients, incontinent epispadias in 5 and neurogenic bladder dysfunction in 1. Of the 40 patients with bladder exstrophy 8 had undergone ureterosigmoidostomy after failure of other types of urinary tract reconstruction (6 had upper tract dilatation before ureterosigmoidostomy). Three patients with previously damaged upper urinary tracts required early postoperative conversion because of severely increasing kidney dilatation. Three other patients required conversion after a mean of 10 years to preserve kidney function. One patient died after 16…

Evolving management of adolescent varicocele

2008

Abstract Objective To review the evolution in indications for treatment and treatment modalities for adolescent varicocele at our centre, and evaluate the impact of varicocelectomy on final outcome. Patients and methods Between 1995 and 2006, we treated 242 left varicoceles. Preoperative assessment included clinical evaluation, measurement of testicular volumes, and colour-Doppler ultrasound (CDUS). A subinguinal varicocelectomy was performed in 124 patients (group A), and a laparoscopic non-artery-sparing Palomo procedure in the remaining 118 (group B). In group B patients, CDUS was also used to investigate the functional anatomy of varicocele, and all the veins found to be refluxing were …

Comprehensive laparoscopic approach to pediatric varicocele based on preoperative color Doppler ultrasound assessment

2008

Abstract: Background This study aimed to assess whether laparoscopic treatment for any kind of varicocele is possible after preoperative identification of refluxing veins by color Doppler ultrasound (CDUS). Methods At the authors'' institution, 98 patients with a median age of 11.3 years (range, 7.1-16 years) were evaluated for a left varicocele. Preoperatively, all the patients underwent ultrasound scan assessment of testicular volume and CDUS to rule out reflux into the internal spermatic vein (ISV), deferential vein, or cremasteric vein. In all the patients, laparoscopic division of the spermatic artery and veins was performed as close as possible to the internal inguinal ring. The other…

Predictors of microvascular complications in type 1 diabetic patients at onset: The role of metabolic memory

2011

Background Several epidemiological studies showed a close association between metabolic control and microvascular complications in type 1 Diabetes Mellitus (T1DM). The aim of our longitudinal observational study was to evaluate the predictive role of the main clinical and biochemical parameters in determining microvascular complications. Methods 376 T1DM patients, hospitalized in our division from 1991 to 2005 (mean follow-up = 10.93 ± 4.26 years) were studied. Stepwise Cox regression analysis was used to identify the influence of residual ß-cell function, ß-cell autoimmunity, HbA1c levels and other clinical and laboratory parameters in the development of microalbuminuria and retinopathy.
