Incidence Patterns and Trends of non-Central Nervous System Solid Tumours in Children and Adolescents. A Collaborative Study of the Spanish Populatio…
2016
Journal Article; OBJECTIVE To describe incidence patterns and trends in children (0-14 years) and adolescents (15-19 age-range) with solid tumours, except those of central nervous system (CNS), in Spain. METHODS Cases were drawn from eleven Spanish population-based cancer registries. Incidence was estimated for the period 1983-2007 and trends were evaluated using Joinpoint regression analysis. RESULTS The studied tumour groups accounted for 36% of total childhood cancers and 47.6% of those diagnosed in adolescence with annual rates per million of 53.5 and 89.3 respectively. In children 0 to 14 years of age, Neuroblastoma (NB) was the commonest (7.8%) followed by Soft-tissue sarcomas (STS) (…
Comparison of the ability of alternative birthweight and fetal weight standards to identify preterm newborns at increased risk of perinatal death
2013
Objective To compare prediction of perinatal deaths among preterm infants based on fetal weight standards versus a new subpopulation-based birthweight standard. Design Population-based cohort study. Setting France. Population A total of 9100 preterm singletons, born between 24 and 36 weeks of gestation in 2000–09, in Burgundy (France). Methods We first classified all newborns as either small for gestational age (SGA) or not, based on alternative fetal weight or birthweight standards, including a new birthweight standard that excludes infants born to mothers with disease related to the weight of a fetus. Based on discrepancies between the different classifications, we then divided the newbor…
Parental informed consent in pediatric cancer trials: A population-based survey in Germany
2012
In Germany, nearly every child afflicted by a malignant dis-ease or a central nervous system tumor is enrolled in a clinicaltrial during treatment. Many of these children are under the age of5 years when they are first diagnosed [1]. The decision whether ornot to participate in a clinical trial is normally made by theparents on behalf of their child. Therefore, ensuring adequatelyinformed parental consent is essential to ethical practice in pedi-atric oncology.However, many empirical studies have revealed difficultieswith the informed consent process when parents are faced withthe decision to enroll their child in a clinical trial. Previous studyfindings have indicated that recalling signing th…
A Novel Technique of Posterolateral Suturing in Thoracoscopic Diaphragmatic Hernia Repair
2017
Background Closure of the posterolateral defect in some cases of congenital diaphragmatic hernia (CDH) can be difficult. Percutaneous transcostal suturing is often helpful to create a complete, watertight closure of the diaphragm. A challenge with the technique is passing the needle out the same tract that it entered so that no skin is caught when the knots are laid down into the subcutaneous tissue. This report describes a novel technique using a Tuohy needle to percutaneously suture the posterolateral defect during thoracoscopic repair of CDH. Case We report a case of a 6-week-old infant who presented with a CDH and ipsilateral intrathoracic kidney that was repaired using thoracoscopic a…
The HIF1α-PFKFB3 Pathway: A Key Player in Diabetic Retinopathy
2021
Abstract Diabetic retinopathy (DR) is the leading cause of blindness for adults in developed countries. Both microvasculopathy and neurodegeneration are implicated in mechanisms of DR development, with neuronal impairment preceding microvascular abnormalities, which is often underappreciated in the clinic. Most current therapeutic strategies, including anti-vascular endothelial growth factor (anti-VEGF)-antibodies, aim at treating the advanced stages (diabetic macular edema and proliferative diabetic retinopathy) and fail to target the neuronal deterioration. Hence, new therapeutic approach(es) intended to address both vascular and neuronal impairment are urgently needed. The hypoxia-induci…

Effects of the number of removed lymph nodes on survival outcome in patients with sentinel node-negative breast cancer.
2021
Abstract Background Sentinel lymph node biopsy is the gold standard surgical technique for axillary staging in patients with clinically node-negative. However, it is still uncertain what is the optimal number of sentinel lymph nodes (SLNs) to be removed to reduce the false-negative rate. The aim of this study was to investigate whether patients with a single negative SLN have a worse prognosis than those with two or more negative SLNs. Methods A retrospective review was conducted on a large series of SLN-negative breast cancer patients. Survival outcomes and regional recurrence rate were evaluated according to the number of removed SLNs. Secondly, the contribution of different adjuvant ther…
Early urinary sodium trajectory and risk of adverse outcomes in acute heart failure and renal dysfunction.
2021
Introduction and objectives: Urinary sodium (UNa+) has emerged as a useful biomarker of poor clinical outcomes in acute heart failure (AHF). Here, we sought to evaluate: a) the usefulness of a single early determination of UNa+ for predicting adverse outcomes in patients with AHF and renal dysfunction, and b) whether the change in UNa+ at 24 hours (Delta UNa24 h) adds any additional prognostic information over baseline values. Methods: This is a post-hoc analysis of a multicenter, open-label, randomized clinical trial (IMPROVE-HF) (ClinicalTrials.gov NCT02643147) that randomized 160 patients with AHF and renal dysfunction on admission to a) the standard diuretic strategy, or b) a carbohydra…
Peripheral Intravenous Access in Preterm Neonates during Postnatal Stabilization: Feasibility and Safety
2017
Background Current European Guideline for resuscitation recommends a centrally positioned umbilical venous catheter as the best option for administering necessary drugs. Especially in preterm infants, a frequently used alternative is the peripheral venous catheter. Methods Two randomized controlled studies were conducted at the Division of Neonatology, Medical University of Graz. During neonatal resuscitation, a standardized protocol was filled out by an uninvolved observer including time points after birth of all attempts of venous puncture, time point of successful venous puncture, and total number of needed attempts. Arterial oxygen saturation (SpO2) and heart rate (HR) were measured usi…

Spinal muscular atrophy (SMA) and Pompe disease (PD) are common neuromuscular disorders during childhood causing progressive weakness of proximal muscles with gait disturbances, loss of ambulation and breathing difficulties. Whereas SMA is the result of a neurogenic atrophy caused by mutations in the SMN1 gene, PD is a lysosomal glycogen storage disease (type II) due to mutations of the GAA gene responsible for the enzyme activity of acid alpha-1,4-glucosidase. PD is treatable by enzyme replacement therapy, but in SMA there is no established curable therapy. We report on a child with genetically proven SMA type III and PD caused by mutations in the SMN1 and GAA genes. A 3 years old girl pre…
