Endoscopic Treatment of Transesophageal Echocardiography-Induced Esophageal Perforation

2018

Perforation of the esophagus is the most severe complication of transesophageal echocardiography (TEE) and can lead to mediastinitis, pleural empyema, or peritonitis. Currently, the majority of patients receive operative treatment with only 6% treated endoscopically. We report our experience with endoscopic and conservative approaches.We retrospectively reviewed all patients treated for esophageal perforation and included all patients with perforation caused by TEE. All patients with perforation of the esophagus by TEE probe underwent conservative or endoscopic treatment, drainage of pleural and mediastinal retentions, and adjusted to antibiotic therapy.From January 2004 to December 2014 a …

Plasma non-cholesterol sterols in primary hypobetalipoproteinemia

2011

Primary hypobetalipoproteinemia (pHBL) is characterized by plasma cholesterol levels ApoB48, and FHBL harbouring as yet unknown molecular defects. Not linked FHBL kindred are not homogeneous in terms of plasma NCS levels. NCS cannot replace genetic HBL analysis.

A difficult diagnosis of coeliac disease: Repeat duodenal histology increases diagnostic yield in patients with concomitant causes of villous atrophy

2018

Abstract Villous atrophy in absence of coeliac disease (CD)-specific antibodies represents a diagnostic dilemma. We report a case of a woman with anaemia, weight loss and diarrhoea with an initial diagnosis of seronegative CD and a histological documented villous atrophy who did not improve on gluten-free diet due to the concomitant presence of common variable immunodeficiency (CVID) and Giardia lamblia infection. This case report confirms that CD diagnosis in CVID patients is difficult; the combination of anti-endomysial antibodies (EmA-IgA), anti-tissue transglutaminase antibodies (tTG-IgAb) antibodies and total IgA is obligatory in basic diagnostic of CD but in CVID are negative. Further…

Self-Reported Long-Term Autonomic Function After Laparoscopic Total Mesometrial Resection for Early-Stage Cervical Cancer: A Multicentric Study.

2017

ObjectivesThis multicentric retrospective study investigates the early and long-term self-reported urinary, bowel, and sexual dysfunctions in early-stage cervical cancer patients who submitted to laparoscopic total mesometrial resection (L-TMMR), total laparoscopic radical hysterectomy, vaginal-assisted laparoscopic radical hysterectomy, and laparoscopic-assisted radical vaginal hysterectomy.MethodsCervical cancer patients, FIGO (International Federation of Gynecology and Obstetrics) stage IA2–IB1/IIA1 who submitted to nerve-sparing radical hysterectomy were recruited. Pelvic functions were assessed within 30 days (early outcome) and 12 months after surgery (long-term outcome).ResultsTwo hu…

Chromoscopy-Guided Endomicroscopy Increases the Diagnostic Yield of Intraepithelial Neoplasia in Ulcerative Colitis

2007

Background & Aims: Because of the large number of biopsy specimens, surveillance colonoscopy in ulcerative colitis (UC) is currently time consuming and significant flat lesions still may be missed. In this study we assessed the value of combined chromoscopy and endomicroscopy for the diagnosis of intraepithelial neoplasias in a randomized controlled trial. Methods: A total of 161 patients with long-term UC in clinical remission were randomized at a 1:1 ratio to undergo conventional colonoscopy or chromoscopy with endomicroscopy. Eight patients were excluded because of insufficient bowel preparation. In the conventional colonoscopic group (n = 73), random biopsy examinations and targeted bio…

Kinetics of Torque Teno virus DNA in stools may predict occurrence of acute intestinal graft versus host disease early after allogeneic hematopoietic…

2020

Torque Teno virus (TTV) DNA load in blood may act as a marker of immune competence after allogeneic hematopoietic stem cell transplant recipients (allo-HSCT). Conflicting data have been reported as to the value of this biomarker for anticipating acute Graft-versus-host disease (aGvHD) occurrence. Here, we hypothesized that quantitation of TTV DNA load in stool specimens early after allo-HSCT could be used to identify patients at high risk of acute intestinal graft-versus-host disease (aIGvHD). In this prospective two-center study we recruited a total of 83 non-consecutive adult patients undergoing allo-HSCT. The study period comprised the first 120 days after allo-HSCT. TTV DNA was quantita…

Cytomegalovirus DNA load monitoring in stool specimens for anticipating the occurrence of intestinal acute graft‐versus‐host disease following alloge…

2020

Background Data have been published suggesting a bidirectional interaction between cytomegalovirus (CMV) infection and acute graft-versus-host disease (aGvHD) in allogeneic hematopoietic stem cell transplant (allo-HSCT) recipients. Here, we hypothesized that prospective CMV DNA monitoring in stool specimens may be useful for predicting subsequent occurrence of intestinal aGvHD (IaGvHD). Methods This two-center study enrolled 121 consecutive adult patients undergoing any modality of allo-HSCT. A total of 1,009 stool specimens were collected (a median of 7 specimens/patient; range, 1-18). CMV DNA monitoring in stools and plasma was performed using real-time PCR assays. Results CMV DNA was det…

Aging modifies receptor expression but not muscular contractile response to angiotensin II in rat jejunum

2022

AbstractThe involvement of renin-angiotensin system in the modulation of gut motility and age-related changes in mRNA expression of angiotensin (Ang II) receptors (ATR) are well accepted. We aimed to characterize, in vitro, the contractile responses induced by Ang II, in jejunum from young (3–6 weeks old) and old rats (≥ 1 year old), to evaluate possible functional differences associated to changes in receptor expression. Mechanical responses to Ang II were examined in vitro as changes in isometric tension. ATR expression was assessed by qRT-PCR. Ang II induced a contractile effect, antagonized by losartan, AT1R antagonist, and increased by PD123319, AT2R antagonist, as well by neural block…

Immunosenescence and anti-immunosenescence therapies: the case of probiotics.

2008

ABSTRACT Aging is a complex process that negatively impacts the development of the immune system and its ability to function. Progressive changes in the T and B cell systems over the life span have a major impact on the capacity to respond to immune challenge. These cumulative age-associated changes in immune competence are termed immunosenescence. This process is mostly characterized by: (1) shrinkage of the T cell repertoire and accumulation of oligoclonal expansions of memory/effector cells directed toward ubiquitary infectious agents; (2) involution of the thymus and the exhaustion of naive T cells; and (3) chronic inflammatory status. Here we discuss possible strategies to counteract t…
