Numerical assessment of induced electric fields in a worker's hand with commonly used metallic implants under exposure to low frequency magnetic fields.

The European Union's Workers' Directive 2013/35/EU on the minimum health and safety requirements regarding the exposure of workers to electromagnetic fields specifies action levels (ALs) for external electric and magnetic fields, which should protect against induced tissue-internal electric field strengthabove the exposure limit values, the latter being defined in order to prevent tissue stimulation at low frequencies. However, although 2013/35/EU explicitly calls for the protection of 'workers at particular risk' (including workers with metallic implants), the AL specified in the Directive have been derived under the assumption that there are no metallic parts present inside the body. Therefore, in the present work, we analysed the situation of a worker's hand and forearm bearing metallic implants (Herbert screw and volar radius plate) used for osteosynthesis after the most common bone fractures of the hand/forearm, exposed to low frequency magnetic fields.

Development and assessment of a loop ligation simulator for laparoscopic appendectomy.

Objective: Loop ligation of the appendix is a challenging surgical skill and well suited to be trained in a simulator. We aimed to develop an affordable and easy-to-build simulator and test its training effect.

Design And Participants: Different materials were tested, and the best training modality was identified by researching the literature.

Surgical simulation of hypospadias repair - High-fidelity, reproducible and affordable animal tissue model.

Introduction: Teaching methods in hypospadias repair are still traditional. Available simulators often lack authenticity in terms of haptic feedback and realistic tissue handling.

Objective: Our aim was to develop a high-fidelity, easily reproducible, and affordable animal tissue model for the advanced surgical simulation of hypospadias repair with realistic haptic feedback and tissue handling.

Surgical Simulation of Posterior Sagittal Anorectoplasty for Rectovestibular Fistula: Low-Cost High-Fidelity Animal-Tissue Model.

Purpose: To provide a high-fidelity, animal tissue-based model for the advanced surgical simulation of a Posterior Sagittal Anorectoplasty (PSARP) for rectovestibular fistula in anorectal malformation (ARM).

Materials And Methods: A chicken cadaver was used to assess the feasibility of simulating a PSARP for rectovestibular fistula in ARM. No modification was required to implement the surgical simulation.

Successful Treatment of a Single Giant Renal Cyst in a Newborn with Drainage and Sclerotherapy.

Simple renal cysts are a scarce entity in pediatric patients and their etiology is unknown in most cases. Usually, they are monitored with ultrasound and regular follow-up of renal function. Surgical treatment is rarely indicated.

Global Irradiation in Children Treated for Hydrocephalus and Its Change over Time-A Single Institutional Analysis.

Radiation exposure early in life is associated with greater incidences of malignancy. Our goal was to quantify radiation exposure in shunt-treated hydrocephalus patients and study changes in the diagnostic modalities used. A single-center, retrospective analysis was performed, and 41 children treated for hydrocephalus using an adjustable ventriculoperitoneal shunt were identified.
