Effects of PEEP on Residual Vascularization in Oesophageal Substitution Gastroplasty by Surface Oximetry-Capnometry and Photoplethysmography
2003
<i>Objective:</i> To evaluate the effects of positive end-expiratory pressure (PEEP) on residual vascularization in gastric tubes for oesophageal replacement. <i>Design:</i> Experimental open study. <i>Materials:</i> Eleven mongrel dogs. <i>Methods:</i> Intestinal parietal blood flow was evaluated by photoplethysmography (PPG) and measurement of surface oxygen (PsO<sub>2</sub>) and carbon dioxide (PsCO<sub>2</sub>) tensions under basal conditions. After Akiyama’s tubular gastroplasty, three levels of PEEP were administered. At each level, fluids were infused to counter the drop in cardiac output. PPG, surface gas tensio…
Pathology Reporting of Resected Pancreatic/Periampullary Cancer Specimen
2018
Pancreatic specimens have always been a great challenge for surgical pathologists due to their anatomic complexity and the difficulty of becoming familiar with these specimens. However, pancreatic specimens are becoming more and more common in many hospitals because of the improvements in surgical techniques and perioperative care that have dramatically reduced the postoperative mortality rate.

A suspected case of hunting accident. Case report
2010
Nowadays, the use of molecular biology in forensics has made it possible to identify human victim and sometimes even the circumstances under which the death occurred through. In our case, a corpse of a 50-years old man with a gunshot wound was found in the woods. The suspected murderer declared that it had been a hunting accident while he shot a wild boar. During the autopsy, a bullet (Borra-bullet Gualandi, 32 gr) was found in the abdomen of the victim. The authors investigated the presence of boar and victim blood both on the bullet, in order to substantiate the thesis of the hunting accident. Laboratory investigations underscored the presence of human cellular material on the bullet, whi…

Remote photoplethysmography system for unsupervised monitoring regional anesthesia effectiveness
2017
Determining the level of regional anesthesia (RA) is vitally important to both an anesthesiologist and surgeon, also knowing the RA level can protect the patient and reduce the time of surgery. Normally to detect the level of RA, usually a simple subjective (sensitivity test) and complicated quantitative methods (thermography, neuromyography, etc.) are used, but there is not yet a standardized method for objective RA detection and evaluation. In this study, the advanced remote photoplethysmography imaging (rPPG) system for unsupervised monitoring of human palm RA is demonstrated. The rPPG system comprises compact video camera with green optical filter, surgical lamp as a light source and a …
Limitations of nasal nitric oxide as a screening method of primary ciliary dyskinesia in childhood
2016
Introduction: Nasal nitric oxide (nNO) has been proposed as a screening tool for primary ciliary dyskinesia (PCD). However, there are no reference values by age in consensus guidelines. Objectives: 1) To analyze differences in nNO among a group of patients with PCD and healthy controls. 2) To determine the proportion of pediatric PCD patients with nNO values similar to healthy population. Methods: Determination of nNO by electrochemical system (NIOX Vario®) in patients with DCP (diagnosis confirmed by digital high speed videomicroscopy) and healthy controls (without asthma, rhinitis or atopic dermatitis), aged between 7 and 60 years. Results: 32 patients (17 children, 53.1%) and 32 controls…
Azacitidine-Containing Induction Regimens Followed by Azacitidine Maintenance Therapy in High Risk Acute Myeloid Leukemia: First Results of the Rando…
2012
Abstract Abstract 412 Background: A large proportion of patients are currently not eligible for genotype-adapted strategies in acute myeloid leukemia (AML), in particular those lacking specific genetic aberrations such as PML-RARA, CBFB-MYH11, RUNX1-RUNX1T1, NPM1 or activating FLT3 mutations. This subgroup of patients accounts for about one-third of all AML patients and mainly includes the large group of AML with myelodysplasia-related changes, AML with recurrent cytogenetic abnormalities [inv(3) or t(3;3), t(9;11), t(v;11q23)] and cytogenetically normal AML (CN-AML) with wild-type NPM1 and FLT3. Prognosis in this subgroup of patients is generally poor. Azacitidine has been shown to be acti…
