Continuity of healthcare for headacahe patients: a problem of communication between headache specialists and general pratictioners

2005

The continuous care of headache patients, from headache centres to general practice, is a managerial problem that is still unsolved in Italy. In fact, if on the one hand patients do not usually go to headache centres because of poor information, on the other hand, if they do, they do not find their general practitioner (GP) sufficiently prepared to continue the management. In Sicily we have formed a dense network of headache centres that we will try to link on the Internet to deal with the problem of poor patients information and poor specialist consultation. We also have faced the problem of the continuous care, trying to overcome "the difficulties of communication between specialists, GPs…

Transarterielle Chemoembolisation (TACE) des Hepatozellulären Karzinoms (HCC) bei Patienten mit Pfortaderthrombose - Erfahrungen

2007

PURPOSE: Comparative analysis of the course of disease in patients with initial diagnosis of portal vein thrombosis in HCC treated with sequential TACE. Evaluation of the efficacy and safety of the method in a selected patient cohort. PATIENTS AND METHODS: The study included 22 patients with HCC that were palliatively treated at least 3 times with TACE. All patients presented a portal vein thrombosis in the initial CT investigation. The TACE-procedure was carried out in regular intervals using a suspension consisting of a fixed dosage of Mitomycin C (10 mg) and 10-20 ml Lipiodol. Follow-up investigations were carried out with contrast enhanced Multislice-CT before and after TACE and control…

Hepatic Sinusoidal Dilatation: A Review of Causes With Imaging-Pathologic Correlation.

2016

Hepatic sinusoids are vascular conduits connecting the portal triad with the central vein. Multiple conditions can lead to sinusoidal dilatation and congestion with resultant stasis of blood within the lumen. The altered hemodynamics associated with hepatic sinusoidal dilatation generally result in heterogeneous enhancement of the hepatic parenchyma on contrast-enhanced computed tomography and magnetic resonance imaging, a pattern often described as “mosaic” enhancement. In this article, we review the causes of hepatic sinusoidal dilatation and the imaging manifestations on contrast-enhanced computed tomography and magnetic resonance.

Strömungsgeschwindigkeits- und Druckmessungen in der Pfortader des wachen Hundes

Sequentielle transarterielle Chemoembolisation (TACE) des hepatozellulären Karzinoms (HCC) - Erfahrungsbericht eines einzelnen Zentrums über 5 Jahre

2007

PURPOSE: To analyze the course of disease of patients treated with sequential TACE and to evaluate the dependent and independent prognostic factors for patient survival using the Cox Proportional Hazard Model. MATERIALS AND METHODS: 94 patients palliatively treated with TACE. Patients were selected if they had been treated at least 3 times. The TACE procedure was carried out at 8-week intervals using a suspension consisting of a fixed dosage of Mitomycin C (10 mg) and 10 ml Lipiodol. Follow-up investigations included contrast-enhanced multislice CT before and after TACE and assessment of the laboratory test results (i. e., blood count, liver enzymes, and coagulation). RESULTS: In 66.7 % of …

Tangential Venous Resections during Robotic-Assisted Pancreaticoduodenectomy: the Results of a Case Series (with Video)

2020

Introduction: Despite the potential advantages in terms of microdissection and microsuturing capabilites, the robotic approach for borderline resectable pancreatic cancer is scarcely reported. Methods: We report our technique for a robotic-assisted pancreaticoduodenectomy with tangential Portal/ Superior Mesenteric Vein resection/reconstruction (RPD PV/SMV).We also compared the surgical outcomes of eight consecutive patients undergoing RPD PV/SMV with that of sixty patients who underwent robotic-assisted pancreaticoduodenectomy (RPD) in the same period of time. Results: A total of eight consecutive patients underwent RPD PV/SMV. We observed an increased estimated blood loss (550 vs 280 mL, …

The role of portal vein thrombosis in the clinical course of inflammatory bowel diseases: report on three cases and review of the literature.

2012

Inflammatory bowel diseases are associated with an increased risk of vascular complications. The most important are arterial and venous thromboembolisms, which are considered as specific extraintestinal manifestations of inflammatory bowel diseases. Among venous thromboembolism events, portal vein thrombosis has been described in inflammatory bowel diseases. We report three cases of portal vein thrombosis occurring in patients with active inflammatory bowel disease. In two of them, hepatic abscess was present. Furthermore, we performed a systematic review based on the clinical literature published on this topic.

Absorption of protein in the early postoperative period in chronic conscious dogs.

1988

Postoperative alterations in amino acid exchange across the intestinal tract and in the capacity for protein absorption were investigated in a chronic canine model. Changes in postoperative splanchnic amino acid exchange consisted of a temporary decrease of total splanchnic amino acid release, including a significant reduction in alanine production, and an increase in glutamine consumption. Contrary to results under stable metabolic conditions, branched chain amino acids were also taken up by the intestine in the early postoperative period. The changes in postoperative amino acid exchange were not, however, reflected by a corresponding alteration in protein transport capacity. The absorptiv…

Hyperhomocysteinemia and the methylene tetrahydrofolate reductase C677T mutation in splanchnic vein thrombosis

2010

Introduction: The role that hyperhomocysteinemia (HH) and the C677T mutation in 5,10-methylenetetrahydrofolate reductase (MTHFR) play in splanchnic vein thrombosis (SVT) remains unclear due to this unusual thrombotic location. Objective: To analyse the possible association of HH with the C677T mutation in the MTHFR gene in SVT. Material and methods: We determined homocysteine levels and the C677T MTHFR mutation, along with classical cardiovascular risk factors, in 48 patients with SVT (18 Budd-Chiari syndrome, 11 mesenteric vein thrombosis, 19 portal vein thrombosis) and 84 controls. Results: In the univariate analysis, patients with SVT showed statistically higher homocysteine levels (P = …
