Fetal malrotation with midgut volvulus: Prenatal diagnosis and planning.

Introduction: Malrotation of the intestinal tract is a congenital malformation commonly found either incidentally or after affected individuals develop signs and symptoms of intestinal obstruction. Malrotation is prone to midgut volvulus that can cause intestinal obstruction and lead to ischemia and necrosis requiring emergent surgical intervention. Rare instances of midgut volvulus have been reported in the literature and carry a high mortality given the difficulty in establishing a diagnosis prior to development of signs of intestinal ischemia and necrosis.

Thoracoscopic Resection of Thoracic Inlet Neuroblastic Tumors in Young Children.

Thoracic inlet (TI) tumors are rare, and can be particularly challenging to resect due to proximity to mediastinal vessels and nerves. Traditional resection is typically performed through "trapdoor" or sternoclavicular incisions. The purpose of our study was to evaluate the feasibility and effectiveness of thoracoscopic resection of this group of tumors.

Variations in Nuss Procedure Operative Techniques and Complications: A Retrospective Review.

Introduction:  The Nuss procedure is the most common and preferred operative correction of pectus excavatum. Surgeon preference and patient factors can result in variations in Nuss procedure technique. We hypothesize that certain techniques are associated with increased risk of complications.

Metastable states in plateaus and multi-wave epidemic dynamics of Covid-19 spreading in Italy.

The control of Covid 19 epidemics by public health policy in Italy during the first and the second epidemic waves has been driven by using reproductive number R(t) to identify the supercritical (percolative), the subcritical (arrested), separated by the critical regime. Here we show that to quantify the Covid-19 spreading rate with containment measures there is a need of a 3D expanded parameter space phase diagram built by the combination of R(t) and doubling time T(t). In this space we identify the Covid-19 dynamics in Italy and its administrative Regions.
