Mathematical simulation of Doppler changes in late-onset smallness; progression patterns of cerebral and umbilical anomalies define two types of late…
2019
To evaluate the progression of Doppler abnormalities in fetuses with late-onset fetal smallness (SGA) that become growth restricted (FGR).524 Doppler examinations of the umbilical and cerebral arteries systems, belonging to 442 late-onset SGA fetuses after week 34, were studied, evaluating by means of the statistical difference with the respective abnormal centiles, the pattern of progression into abnormal Doppler values and the distribution and cumulative sum of Doppler anomalies according to the interval to delivery.Only one third (33.5%,Two thirds of late-onset fetal smallness occurs without hemodynamic changes. In half of the remaining cases an initial cerebral vasodilation defines a gr…
Novel Device for Endoluminal Esophageal Atresia Repair: First-in-Human Experience
2021
Thoracoscopic esophageal atresia (EA) repair affords many benefits to the patient; however, intracorporeal suturing of the anastomosis is technically challenging. Esophageal magnetic compression anastomosis (EMCA) is a compelling option for endoluminal EA repair, but available EMCA devices have prohibitive rates of recalcitrant stricture. Connect-EA is a new endoluminal EMCA device system that employs 2 magnetic anchors with a unique mating geometry designed to reliably create a robust anastomosis and decrease rates of leak and stricture. We describe our first-in-human experience with this novel endoluminal device for staged EA repair in 3 patients (Gross type A, B, and C) at high risk for …
An experimental study on magnetic esophageal compression anastomosis in piglets.
2019
Abstract Introduction Fashioning a patent, watertight anastomosis in patients with esophageal atresia is a challenging task in pediatric surgery, particularly when performed under tension. A reproducible suture-less alternative would decrease operative time. We evaluated magnetic esophageal compression anastomoses in a novel bypass-loop swine model. Methods Eight-week-old piglets underwent thoracotomy to mobilize the esophagus at the carina to create a U-shaped loop. Custom-made 8 mm diameter Neodymium Magnets were inserted into the esophagus proximal and distal to the loop, then mated side-to-side at the future anastomosis site. Pigs were observed for 8 (n = 4), 10 (n = 6), and 12 (n = 2) …
Thoracoscopic Lung Biopsies and Resections in Children
2016
Pediatric surgeons are frequently faced with a variety of indications regarding the lung. Pulmonary lesions found on imaging studies may be congenital, malignant, infectious, or inflammatory in nature. Often, only a biopsy can make the diagnosis and guide subsequent management. In other cases, resection may be curative.
The Role of Pediatricians in Caring for the Well-Being of Children Living in New Types of Families.
2017
Pediatricians are on the front line of child care and advocacy, and it is their role to promote children's well-being and to help parents raise healthy children, independent of the configuration of their families. This report aims to draw attention to the evolving social scenarios and to emphasize that pediatricians must be trained to coordinate new challenges that may arise from differently configured families, particularly single-parent and same-sex–parent families.
Bladder augmentation and urinary diversion in patients with neurogenic bladder: Surgical considerations
2010
Segments from almost all parts of the bowel have been used for urinary diversion. As a result, the available absorptive surface area of the bowel is reduced, and the incorporation of bowel segments into the urinary tract may have metabolic consequences. This is an area somewhat neglected in the literature. Metabolic complications are rare, but sub-clinical metabolic disturbances are quite common. Several studies have demonstrated that some of the absorbent and secreting properties of the bowel tissue are preserved after incorporation into the urinary tract. Hyperchloraemic metabolic acidosis can occur if ileal and/or colon segments are used, as well as malabsorption of vitamin B(12) and bil…
Hemodynamic effects of dobutamine in children with cardiovascular failure.
1982
The effect of dobutamine, a synthetic catecholamine, was studied in 12 patients aged one day to 14 years with low cardiac output syndromes. After initial stabilization of the patients dobutamine was administered by continuous infusion in a dosage of 7.5 or 10 μg/kg/min. Heart rate, cardiac output (using thermodilution technique and/or pulse contour method), mean systemic and mean pulmonary artery pressures were determined before and after the dobutamine infusion. Systemic and pulmonary vascular resistances, cardiac index and stroke volume index were calculated. Cardiac output and cardiac index increased significantly in every patient, whereas the heart rate changed only slightly, suggesting…
Clinical Simulation in pediatrics and neonatology using EDISON: an educational innovation project
2021
Introduction: Clinical simulation is a tool that allows creating controlled and safe spaces that mimic reality, where students can acquire skills and abilities prior to facing real situations. Methodology: This is a study with two phases. The first quasi-experimental phase where 3 questionnaires were used; two of them to assess knowledge (pretest - posttest) and the other one to assess the satisfaction of the training action. And the second phase was analytical, where the effectiveness of a training intervention in a confinement context based on the use of audiovisual materials created through EDISON was evaluated. Results: In 2019 the average satisfaction of the students was 9.22 (SD 0.72)…
Evaluation of the Department of Neurosurgery of the Seoul National University Hospital
2013
The Department of Neurosurgery (DNS) of the Seoul National University Hospital (SNUH), belongs to the largest and oldest such institutions in Korea. Because of its growing reputation it is hardly surprising that the DNS draws visitor and scholars for clinical education and academic exchange from far beyond Korea. I myself visited the SNUH in February and March 2013. During this time I composed this evaluation in which I compare the DNS to my home Department at the Johannes Gutenberg-University in Mainz/Germany, as well as the situation of Neurosurgery in Korea and Germany in general. In the first part this evaluation summarizes data concerning equipment, staff and organizational structure, …
