A noninvasive postoperative clinical score to identify patients at risk for postoperative pulmonary complications: The air-test score

2020

BACKGROUND: Postoperative pulmonary complications (PPCs) negatively affect morbidity, healthcare costs and postsurgical survival. Preoperative and intraoperative peripheral oxyhemoglobin saturation (SpO2) levels are independent risk factors for postoperative pulmonary complications (PPCs). The air-test assesses the value of SpO2 while breathing room-air. We aimed at building a clinical score that includes the air-test for predicting the risk for PPCs. METHODS: This is a development and validation study in patients -randomly divided into two cohorts- from a large randomized clinical trial (iPROVE) that enrolled 964 intermediate-to-high risk patients scheduled for abdominal surgery. Arterial …

Abdominal wall incisional hernia repair improves respiratory function: results after 3 years of follow-up

2020

Abstract Purpose Hernias severely impact patient quality of life (QoL), and 80% of patients require a surgical operation. Moreover, hernias are responsible for respiratory function alterations. This study aims to investigate the postoperative alterations in respiratory function after open ventral hernia repair in patients with incisional hernia. Methods Patients operated on at the Policlinico “Paolo Giaccone” at Palermo University Hospital between January 2015 and December 2016 were identified in a prospective database. Fifty-one patients were enrolled in the study. The respiratory outcome measures used were forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), FEV1/FVC ratio…

Postprandial triglyceridaemia is modulated by insulin resistance but not by grade of obesity in abdominal and morbid obese subjects

2020

Background Obesity is associated with high cardiovascular risk. Postprandial lipidaemia has been associated with cardiovascular disease risk. Our aim was to identify whether anthropometric parameters, insulin resistance (IR) and/or fasting plasma triglycerides may determine postprandial changes in lipoprotein concentrations in abdominal and morbid obese subjects. Methods We have studied 20 non-diabetic, normolipidaemic subjects with abdominal obesity, 20 morbid obese subjects and 20 healthy individuals, that have similar age and gender. In all of them a standardised oral fat load test (OFLT) with unsaturated fat was performed. Results During the OFLT, the postprandial triglycerides response…

Abdominal obesity, insulin resistance, and metabolic syndrome in a southern European population.

2003

Background: Our objective was to investigate the relationship between abdominal obesity (AO), as measured by waist circumference (WC), insulin resistance (IR), and components of the metabolic syndrome (MS). Methods: A cross-sectional study was carried out with 283 subjects (130 males and 153 females aged 25–65 years) from a primary care outpatient clinic in Valencia (Spain) over a period of 1 year. Body mass index (BMI), waist circumference (WC), blood pressure (BP), total cholesterol, triglycerides, HDL-C, glucose, and insulin were measured by standard methods. IR was defined as HOMA-IR equal to or greater than 3.8. Results: The prevalence of IR was 39.6%. Subjects were divided into groups…

Histological findings of the internal inguinal ring in patients having indirect inguinal hernia

2009

BACKGROUND: Aiming to deepen the understanding of the factors involved in the genesis of groin hernia, this study is focused on identifying the histological changes within the muscle fibers of the internal inguinal ring in patients having indirect inguinal hernia. METHODS: In eight patients with primary or recurrent bilateral indirect inguinal hernia who underwent a Stoppa open posterior inguinal hernia repair, a tissue specimen from the edge of the internal inguinal ring was biopsied and histologically examined. RESULTS: In all of the tissue samples, remarkable degenerative changes such as fibrohyaline degeneration of the muscle fibers, vascular congestion, and phlogistic infiltration thro…

Diamond-Shaped Mini-Craniotomy: A New Concept in Neurosurgery

2021

Abstract Background We describe, step by step, a modified, less invasive, diamond-shaped mini-craniotomy that optimizes dural opening and can be performed in elderly patients affected by acute subdural or intracerebral hematomas, in therapy with antiplatelets or anticoagulants. Methods We retrospectively analyzed the clinical records of 67 patients (mean age of 78.5 years) treated in our institution, during a period of 10 years, with this novel diamond-shaped craniotomy. Seventeen patients were treated for intracerebral hemorrhage and 50 patients for acute subdural hematomas. All the patients were in therapy with antiplatelets or anticoagulants. Results Approach-related complications were n…

Serum concentrations of collagen degrading enzymes and their inhibitors after downhill running

2001

In the present study the release of proteins degrading extracellular matrix compounds to circulation was measured after damaging exercise in humans. Muscle damage was induced by downhill running; furthermore, the exercise was performed at both cold temperature (5 degrees C) and room temperature (22 degrees C) to study also the possible effect of environmental temperature on serum concentrations of matrix metalloproteinases MMP-2 and MMP-9, tissue inhibitors of metalloproteinases TIMP-1 and TIMP-2, and MMP-2/TIMP-2 complex, and muscle damage monitored by serum creatine kinase measurements. Results were compared with those obtained from patients having rhabdomyolysis, myositis and Becker musc…

Anwendungsm�glichkeiten der intraoperativen Sonographie

1983

Sonographie, Computertomographie, Angiographie und endoskopisch retrograde Cholangiopancreaticographie haben sich in der Allgemein- und Gefaschirurgie als wertvolle Untersuchungsmethoden etabliert. Schwierigkeiten bestehen jedoch manchmal in der Korrelation der Praoperativen Befunde mit dem intraoperativen Befund. Hier ist das Anwendungsgebiet der intraoperativen Sonographie (IOS) zu sehen. Sie bietet dem Chirurgen eine zusatzliche Information durch Darstellung von pathologischen Gefasprozessen, Kontrolle von Gefasanastomosen, intraoperative FlowMessung in Gefasen, Lokalisationsdiagnostik in parenchymatosen Organen. Die intraoperative Sonographie ist somit ein neues Instrument des Chirurgen…
