Robotic Setup Promises Consistent Effects of Multilocular Gastrointestinal Electrical Stimulation: First Results of a Porcine Study

2020

<b><i>Background:</i></b> Electrical stimulation (ES) of several gastrointestinal (GI) segments is a promising therapeutic option for multilocular GI dysmotility, but conventional surgical access by laparotomy involves a high degree of tissue trauma. We evaluated a minimally invasive surgical approach using a robotic surgical system to perform electromyographic (EMG) recordings and ES of several porcine GI segments, comparing these data to an open surgical approach by laparotomy. <b><i>Materials and Methods:</i></b> In 5 acute porcine experiments, we placed multiple electrodes on the stomach, duodenum, jejunum, ileum, and colon. Three experime…

Prophylaxis of venous thromboembolism in elderly patients with multimorbidity

2013

none 327 si Pharmacological thromboprophylaxis (TP) is known to reduce venous thromboembolism (VTE) in medical inpatients, but the criteria for risk-driven prescription, safety and impact on mortality are still debated. We analyze data on elderly patients with multimorbidities admitted in the year 2010 to the Italian internal medicine wards participating in the REPOSI registry to investigate the rate of TP during the hospital stay, and analyze the factors that are related to its prescription. Multivariate logistic regression, area under the ROC curve and CART analysis were performed to look for independent predictors of TP prescription. Association between TP and VTE, bleeding and death in …

Multicenter Multireader Evaluation of an Artificial Intelligence-Based Attention Mapping System for the Detection of Prostate Cancer With Multiparame…

2020

OBJECTIVE. The purpose of this study was to evaluate in a multicenter dataset the performance of an artificial intelligence (AI) detection system with attention mapping compared with multiparametric MRI (mpMRI) interpretation in the detection of prostate cancer. MATERIALS AND METHODS. MRI examinations from five institutions were included in this study and were evaluated by nine readers. In the first round, readers evaluated mpMRI studies using the Prostate Imaging Reporting and Data System version 2. After 4 weeks, images were again presented to readers along with the AI-based detection system output. Readers accepted or rejected lesions within four AI-generated attention map boxes. Additio…

In vivo definition of parieto-motor connections involved in planning of grasping movements

2010

We combined bifocal transcranial magnetic stimulation (TMS) and diffusion tensor imaging (DTI) tractography to investigate in humans the contribution of connections originating from different parietal areas in planning of different reaching to grasp movements. TMS experiments revealed that in the left hemisphere functional connectivity between the primary motor cortex (M1) and a portion of the angular gyrus (AG) close to the caudal intraparietal sulcus was activated during early preparation of reaching and grasping movements only when the movement was made with a whole hand grasp (WHG) towards objects in contralateral space. In contrast, a different pathway, linking M1 with a part of the su…

Prognostic Impact of Hyponatremia and Hypernatremia in COVID-19 Pneumonia. A HOPE-COVID-19 (Health Outcome Predictive Evaluation for COVID-19) Regist…

2020

Dysnatremia is associated with increased mortality in patients with community-acquired pneumonia. SARS-COV2 (Severe-acute-respiratory syndrome caused by Coronavirus-type 2) pneumonia can be fatal. The aim of this study was to ascertain whether admittance dysnatremia is associated with mortality, sepsis, or intensive therapy (IT) in patients hospitalized with SARS-COV2 pneumonia. This is a retrospective study of the HOPE-COVID-19 registry, with data collected from January 1th through April 31th, 2020. We selected all hospitalized adult patients with RT-PCR-confirmed SARS-COV2 pneumonia and a registered admission serum sodium level (SNa). Patients were classified as hyponatremic (SNa <…

Effects of bemiparin on airway responses to antigen in sensitized Brown-Norway rats.

2004

Heparins have demonstrated activity in asthma. The effects of bemiparin, a low molecular weight heparin, were examined on antigen-induced responses in sensitized Brown-Norway rats. Inhaled bemiparin (1 mg/ml) reduced the acute bronchospasm produced by aerosol antigen, prevented airway hyperresponsiveness to 5-hydroxytryptamine postantigen exposure, and reduced the eosinophil count (from 0.205+/-0.062 to 0.054+/-0.016 x 10(6) cells/ml in antigen and antigen+bemiparin groups, respectively; P<0.05), eosinophil peroxidase activity, and proteins in the bronchoalveolar lavage fluid (BALF), as well as the transiently augmented mucin Muc5ac expression. Hyperresponsiveness to adenosine was not affec…

Postoperative intussusception in childhood

1998

Over a period of 10 years, five children developed postoperative intussusception after intra-abdominal procedures at the Department of Pediatric Surgery of the Johannes Gutenberg University Mainz. Two appendectomies, one ileal resection for a Meckel's diverticulum, one operative procedure for Hirschsprung's disease plus intestinal neuronal dysplasia type B, and one hiatoplasty with jejunostomy preceded the intussusception. Three of the five children were older than 2 years. The clinical symptoms consisted primarily of abdominal distension, diffuse abdominal pain, bilious vomiting, and rectal bleeding in one case. Preoperative diagnosis was achieved in four cases by abdominal ultrasound. Pla…

Subcutaneous emphysema, pneumomediastinum and pneumoperitoneum after diagnostic colonoscopy for ulcerative colitis: a rare but possible complication …

2010

Dear Editor: Colonoscopy is regarded as a safe procedure, but complications may occur. The most dreaded are perforation and massive bleeding of the colon. The incidence of perforation is low but, despite increased experience with the procedure, it remains unchanged over time and in a large population study ranges from 0.6 to 1 per 1.000 procedures, depending on the centre and the data source. Few studies have assessed risk factors for colonoscopy-related bleeding and perforation. Gatto et al. have reported that there was a significant trend in the incidence of perforation with increasing age, people aged 75 years or older having a fourfold risk as compared to those aged 65–69 years; same re…

Laparoscopic removal of mullerian duct remnants in boys

2003

Abstract: Purpose: Mullerian duct remnants (MDRs) are present in a male pseudohermaphroditic form characterized by failure of the mullerian duct to regress due to insufficient production or peripheral action of mullerian inhibiting substance. The MDR can be asymptomatic but it often results in infections, stones and voiding troubles. Furthermore, it may develop into a neoplasm. Therefore, surgery is mandatory for large MDRs and symptomatic patients. Laparoscopic removal is described. Materials and Methods: Six males were treated from February 1998 to February 2003. Age at surgery was between 3 and 18 years (mean 8.6). All patients showed severe hypospadias and 2 had mixed gonadal dysgenesis…

Evolving management of adolescent varicocele

2008

Abstract Objective To review the evolution in indications for treatment and treatment modalities for adolescent varicocele at our centre, and evaluate the impact of varicocelectomy on final outcome. Patients and methods Between 1995 and 2006, we treated 242 left varicoceles. Preoperative assessment included clinical evaluation, measurement of testicular volumes, and colour-Doppler ultrasound (CDUS). A subinguinal varicocelectomy was performed in 124 patients (group A), and a laparoscopic non-artery-sparing Palomo procedure in the remaining 118 (group B). In group B patients, CDUS was also used to investigate the functional anatomy of varicocele, and all the veins found to be refluxing were …
