Reproducibility of Regional DEXA Examinations of Abdominal Fat and Lean Tissue
2013
<b><i>Objective: </i></b>The aim of this study was to develop and test the validity of a new repeatable method to delimit abdominal areas for follow-up of fat mass (FM) and lean tissue mass (LM) in DEXA examinations<i>. </i><b><i>Methods: </i></b>37 male volunteers underwent two DEXA examinations. Total body FM and LM measurements and corresponding abdominal measurements in a carefully defined region were calculated from the first scan. After repositioning of the subjects and a second scan, the delimited region was copied and the abdominal tissues re-calculated. <b><i>Results: </i></b>The mean LM of the abdo…
Visceral adiposity index is associated with insulin sensitivity and adipocytokine levels in newly diagnosed acromegalic patients.
2012
Context: The visceral adiposity index (VAI) has proved to be a marker of visceral adipose dysfunction, strongly associated with insulin sensitivity in both the general and specific populations of patients at metabolic risk. Objective: The objective of the study was to test VAI as a useful tool to assess early metabolic risk in acromegaly. Patients: Twenty-four newly diagnosed acromegalic patients (11 women and 13 men, aged 54.9 ± 13.6 yr) were grouped into those with normal (group A, n = 13, 54.2%) and those with high VAI (group B, n = 11, 45.8%). Outcome Measures: Glucose, hemoglobin A1c, nadir and area under the curve (AUC) of GH (AUCGH) during the oral glucose tolerance test, AUCCpeptide…
Prospective Evaluation of Positron Emission Tomography in the Preoperative Staging of Esophageal Carcinoma
2004
Hypothesis Positron emission tomography (PET) is a useful tool in the selection of patients with esophageal cancer who may not benefit from esophageal resection. Design Case series. Setting Tertiary care hospital. Patients Eighty-one patients with newly diagnosed esophageal cancer who underwent PET and computer tomography (CT) of the chest and abdomen (and of the neck in 45 patients) within 45 days were included. Main Outcome Measures We calculated the sensitivity and specificity in detecting metastatic sites on the basis of 31 histologically verified lesions. In addition to results obtained on CT, the information provided by PET was evaluated with a view to the choice of management strateg…
New mesh shape and improved implantation procedure to simplify and standardize open ventral hernia repair: a preliminary report.
2010
Introduction Issues in ventral hernia repair are represented by the need for mesh fixation and how to assure a sufficient mesh overlap of the defect. Aiming to resolve these problems, this study describes a modified technique for ventral and incisional hernia repair based upon a newly developed mesh with a special design. This new type of implant allows broader coverage of the abdominal wall and results in tension- and fixation-free repair. Materials and methods A unique geometrically shaped mesh consisting of a large central body and radiating arms was used to repair ventral or incisional hernia. The mesh was intended not to be point-fixated. The friction of the straps passing through the …
Tentacle-shaped mesh for fixation-free repair of umbilical hernias
2019
Purpose: Mesh fixation and broad overlap represent an open issue in umbilical hernia repair. A proprietary-designed implant with tentacle straps at its boundary has been developed to ensure a suture-free repair and a broader coverage of the abdominal wall. The study describes the results of umbilical hernia procedures carried out with the tentacle-shaped implant and the related surgical technique. Methods: A proprietary tentacle-shaped flat mesh having a central body with integrated radiating arms at its edge was used to repair large umbilical hernias in 62 patients. The implant was placed in preperitoneal sublay. The friction of the straps, crossing the abdominal wall thanks to a special n…
Homocysteine levels and the metabolic syndrome in a Mediterranean population: A case-control study
2011
Hyperhomocysteinemia (HH) and metabolic syndrome (MS) are associated with increased cardiovascular risk. However, whether there is a link between MS or its components and homocysteine levels in a population without cardiovascular disease is not well established. We conducted a case-control study in 61 MS patients (41 males, 20 females, aged 51 ± 11 years) and in 98 controls without MS (59 males, 39 females, aged 50 ± 10 years) to ascertain the association between MS and HH, and with inflammatory markers. MS was classified according to the updated ATPIII criteria [17]. No differences in homocysteine levels were observed when comparing MS patients and controls (12.0 ± 3.18 μM vs. 11.9 ± 3.5 μ…
Increased expression of markers of early atherosclerosis in patients with inflammatory bowel disease.
2016
Recent studies documented an increased cardiovascular risk in patients with inflammatory bowel disease (IBD). Our study aimed at investigating the prevalence of intima-media thickness (IMT) of the carotid arteries and the arterial stiffness indices as markers of early atherosclerosis in young IBD patients.We recruited 68 consecutive IBD patients, and 38 matched healthy controls less than 45years old (median age 31.6±8.1years). Clinical and demographic features, cardiovascular risk factors, history of cardiovascular events, concomitant therapies were registered on a dedicate database. Carotid IMT was evaluated by using high resolution B-mode ultrasonography. Arterial stiffness was assessed b…
Genetic predisposition to thrombophilia in inflammatory bowel disease
2011
BACKGROUND Inflammatory bowel disease (IBD) is linked to a definite risk of thromboembolic events (TE), but data on the role of prothrombotic genetic mutations are conflicting. STUDY Fourteen genetic factors involved in TE pathogenesis were investigated in a homogeneous cohort of Sicilian patients with IBD with and without history of TE and in healthy controls. Forty IBD patients (21 CD, 19 UC) and 20 healthy individuals were enrolled. Genetic testing was based on the reverse hybridization principle by a commercial assay that analyzes 14 polymorphisms involved in thrombophilia and cholesterol metabolism. The rate of genetic polymorphisms and mutations was compared between IBD patients and h…
Requirement and postoperative outcomes of abdominal panniculectomy alone or in combination with other procedures in a bariatric surgery unit.
2009
Abstract Background A high percentage of patients present with redundant skin folds after bariatric surgery. This study aims to quantify the need for panniculectomy after open bariatric surgery and to analyze the postoperative outcomes. Methods A retrospective cohort study was performed. The patients were divided into 2 groups: group DLP, patients who underwent an abdominal panniculectomy alone and group DLP+, those who underwent panniculectomy in association with another surgical procedure. Results Four hundred forty-six patients underwent open bariatric surgery and 130 patients (29%) subsequently required an abdominal dermolipectomy. Seventy-six percent presented also incisional hernia an…
Botulinum toxin to avoid component separation in midline large hernias.
2020
Abstract Background The goal of our study was to compare results in patients with large midline incisional hernia using modified anterior component separation versus preoperative botulinum toxin and following Rives repair, with a focus on surgical site occurrences, possibility of fascial closure, duration of hospital stay, and hernia recurrence rate. Methods From to March 2016 to June 2019, a prospective comparative study was performed in 80 consecutive patients with large midline incisional hernias and hernia transverse diameters between 11 and 17 cm under elective hernia repair at our tertiary center. Two groups were analyzed prospectively: 40 patients with preoperative botulinum toxin ad…
