Prothrombinase-Induced Clotting Time Assay for Determination of the Anticoagulant Effects of Unfractionated and Low-Molecular-Weight Heparins, Fondap…

2008

The prothrombinase-induced clotting time assay (PiCT, Pentapharm, Basel, Switzerland) is a clotting assay sensitive to factor Xa and factor IIa inhibitors. It is based on the addition of factor Xa and snake venom RVV-V (Russell viper venom factor V activator) specifically activating factor V and phospholipids to platelet-poor plasma. Following an incubation time, the mixture is recalcified and the clotting time is determined. An almost linear dose-response and high sensitivity of the assay for unfractionated heparin (UFH), low-molecular-weight heparins (LMWHs), r-hirudin, and argatroban was found. Fondaparinux showed a nonlinear dose-response. By using ex vivo samples, the following Pearson…

The diagnostic significance of cholescintigraphy and ultrasound examination in cholestatic syndromes in infancy

1988

Thirty-three neonates and infants with cholestatic syndromes of various etiologies were evaluated by cholescintigraphy and ultrasound examinations. The results of these two diagnostic procedures were compared with the final diagnosis as confirmed by liver biopsy and/or laparotomy and the clinica follow-up of the infants. Fourteen patients had an obstructive cholangiopathy (11 biliary atresia, 2 choledochal cysts, 1 congenital choledochal stenosis), 13 had neonatal hepatitis, and 6 had cholestasis of another etiology. Typical ultrasonic and/or scintigraphic findings confirmed or excluded the need for surgical exploration in 28 patients. Thus, for must infants with cholestatic syndromes it is…

Clinical strategies for the management of intestinal obstruction and pseudo-obstruction. A Delphi Consensus study of SICUT (Società Italiana di Chiru…

2016

Intestinal obstructions/pseudo-obstruction of the small/large bowel are frequent conditions but their management could be challenging. Moreover, a general agreement in this field is currently lacking, thus SICUT Society designed a consensus study aimed to define their optimal workout.The Delphi methodology was used to reach consensus among 47 Italian surgical experts in two study rounds. Consensus was defined as an agreement of 75.0% or greater. Four main topic areas included nosology, diagnosis, management and treatment.A bowel obstruction was defined as an obstacle to the progression of intestinal contents and fluids generally beginning with a sudden onset. The panel identified four major…

Corrigendum to “Hiatal Hernia Repair with Gore Bio-A Tissue Reinforcement: Our Experience”

2015

Type I hiatal hernia is associated with gastroesophageal reflux disease (GERD) in 50-90% of cases. Several trials strongly support surgery as an effective alternative to medical therapy. Today, laparoscopic fundoplication is considered as the procedure of choice. However, primary laparoscopic hiatal hernia repair is associated with upto 42% recurrence rate. Mesh reinforcement of the crural closure decreases the recurrence but can lead to complications, above all nonabsorbable ones. We experiment a new totally absorbable mesh by Gore. Case. We present a case of a 65-year-old female patient with a 6-year classic history of GERD. Endoscopy revealed a large hiatal hernia and esophagitis. pH stu…

Quality-based assessment of camera navigation skills for laparoscopic fundoplication.

2020

Summary Laparoscopic fundoplication is considered the gold standard surgical procedure for the treatment of symptomatic hiatus hernia. Studies on surgical performance in minimally invasive hiatus hernia repair have neglected the role of the camera assistant so far. The current study was designed to assess the applicability of the structured assessment of laparoscopic assistance skills (SALAS) score to laparoscopic fundoplication as an advanced and commonly performed laparoscopic upper GI procedure. Randomly selected laparoscopic fundoplications (n = 20) at a single institute were evaluated. Four trained reviewers independently assigned SALAS scoring based on synchronized video and voice rec…

Trattamento laparoscopico del megacolon agangliare

2007

Recent trends in surgery for Hirschsprung's disease have been toward early repair and fewer surgical stages. Laparoscopy can be used for colon pull-through even in neonates adding the advantages of a minimally invasive approach to those of the traditional technique. the personal experience in the use of laparoscopically assisted endorectal pull-through in the treatment of Hirschsprung's disease in reported. the advantages it offers are outlined, including excellent visualization of the operative field, accurate dissection of the bowel from pelvic structures, and minimally invasive abdominal wounds. Preliminary results show that laparoscopically assisted endorectal pull-through is one of the…

Total curvatures of convex hypersurfaces in hyperbolic space

1999

We give sharp upper estimates for the difference circumradius minus inradius and for the angle between the radial vector (respect to the center of an inball) and the normal to the boundary of a compact $h$-convex domain in the hyperpolic space. We apply these estimates to get the limit at the infinity for the quotients Volume/Area and (Total $k$-mean curvature)/Area of a family of $h$-convex domains which expand over the whole space. The theorem for the first quotient gives an extension to arbitrary dimension of a result of Santalo and Yanez for the hyperbolic plane.

THE HOROSPHERICAL GEOMETRY OF SUBMANIFOLDS IN HYPERBOLIC SPACE

2005

Some geometrical properties associated to the contact of submanifolds with hyperhorospheres in hyperbolic -space are studied as an application of the theory of Legendrian singularities.

Observational study: The use of the ventralight Echo PS (positioning system) prosthesis in the treatment of incisional hernia

2020

The treatment of incisional hernias, especially those that are multiple or recurring, has always represented important challenges for surgeons. An incisional hernia is a mechanical damage of the abdominal wall that can result in respiratory problems and alterations of splanchnic circulation, especially when in large size hernias. The increasing availability of prostheses with greater resistance Romato infections and tension, lightness, biocompatibility, and reduced visceral adhesions has improved outcomes and minimized relapses. It is still important, however, to carefully choose the type of prosthesis and surgical technique, whether laparotomic or laparoscopic, correlated to the positionin…
