Management of rectal cancers in relation to treatment guidelines: a population-based study comparing Italian and French patients
2014
Few studies have investigated rectal cancer management at the population level. We compared how rectal cancers diagnosed in Italy (2003-2005) and France (2005) were managed, and evaluated the extent to which management adhered to European guidelines.Samples of 3938 Italian and 2287 French colorectal cancer patients were randomly extracted from 8 and 12 cancer registries respectively. Rectal cancer patients (860 Italian, 559 French) were analysed. Logistic regression models estimated odds ratios (ORs) of being treated with curative intent, receiving sphincter-saving surgery, and receiving preoperative radiotherapy.Similar proportions of Italian and French patients were treated with curative …
Pathological Evaluation of Mesocolic Resection Quality and Ex Vivo Methylene Blue Injection
2012
BACKGROUND: Although the National Quality Forum has endorsed the harvest of ≥12 lymph nodes as a standard quality indicator for colon cancer surgery, this minimum quantity is not reached in many centers. OBJECTIVE: The aim of this study was to assess the impact of the implementation of a mesocolon evaluation pathological protocol and ex vivo arterial methylene blue injection on the number of nodes harvested after colon cancer resection. DESIGN: A prospective series was compared with a historical group. SETTINGS: This study was conducted by a specialized colorectal multidisciplinary team at a tertiary teaching hospital. PATIENTS: From June 2009 to December 2009, all the specimens after colon…
Effects of Steatosis on Hepatic Hemodynamics in Patients with Metabolic Syndrome
2015
The aim of our study was to assess the hemodynamic changes in hepatic and splenic circulation using B-mode ultrasonography and color Doppler ultrasonography, in a population of patients with metabolic syndrome divided with respect to the presence or absence of steatosis diagnosed by ultrasonography. One hundred forty-one patients were included in the study. The severity of non-alcoholic fatty liver disease was classified as mild, moderate or severe. Visceral fat thickness, longitudinal diameter of the spleen, diameter of the portal vein, mean maximum portal vein flow velocity, hepatic artery and splenic artery resistivity indexes and hepatic vein flow phasicity were measured. Non-alcoholic …
Visual quality after diffractive intraocular lens implantation in eyes with previous hyperopic laser in situ keratomileusis
2010
To evaluate distance, intermediate, and near visual quality in eyes with diffractive intraocular lens (IOL) implantation after previous hyperopic laser in situ keratomileusis (LASIK).Fernández-Vega Ophthalmological Institute, Oviedo, Spain.Cohort study.Corrected distance visual acuity (CDVA) at 12.5%, 25.0%, and 100% contrast levels under photopic and mesopic conditions; uncorrected (UNVA) and distance-corrected (DCNVA) near visual acuity, defocus curves, and corneal higher-order aberrations (HOAs) were measured in eyes that had AcrySof Restor SN60D3 spherical IOL implantation (study group) and in phakic eyes (control group) after hyperopic LASIK.Under photopic conditions at 100% contrast, …
Troponin I release after intravenous treatment with high furosemide doses plus hypertonic saline solution in decompensated heart failure trial (Tra-H…
2012
Background High values of cardiac troponin in acute decompensated congestive heart failure (ADHF) identify patients at higher risk and worsened prognosis. A cardiac troponin increase during therapy indicates the need for more appropriate intervention, aimed at compensating cardiac disease and effectively minimizing myocardial wall stress and subsequent cytolysis. This study evaluated the effects of an intravenous high dose of furosemide with (group A) or without small volume hypertonic saline solution (HSS) (group B) on myocardial cytolysis in patients with ADHF. Methods A total of 248 consecutive patients with ADHF (148 men, mean age 74.9 ± 10.9 years) were randomly assigned to group A or …
Perforated giant mycotic aneurysm of mitral valve in a drug-addicted young man: Rare complication of infective endocarditis
2017
Infective endocarditis (IE) affects patients at high clinical risk and may present as an acute and rapidly progressive, subacute or chronic infection. Transthoracic and transesophageal echocardiography represent the key diagnostic method in IE diagnosis. In particular, three-dimensional transesophageal echocardiography represents the imaging technique that allows to establish with adequate accuracy dimensions, shape, and localization of endocarditis vegetations. In our case, we show a huge vermiform mycotic aneurysm in an immunodeficient young drug-addicted man with severe mitral valve regurgitation and the additive value of three-dimensional transesophageal echocardiography in this specifi…

Role of intraoperative ultrasound in the screening of liver metastases from colorectal carcinoma: initial experiences.
1989
The aim of this study was to assess the utility of intraoperative ultrasound (IOUS) in the diagnosis and management of liver metastases from colorectal carcinoma. IOUS was performed on a consecutive series of 70 patients undergoing surgery for colorectal carcinoma, with follow-up ranging from 6 to 24 months. In ten cases (14.3%), 13 metastatic tumours were diagnosed; only six of these had been found by preoperative workup and/or surgical inspection. Seven (53.9%) small metastatic liver lesions were identified only by IOUS. None of the lesions diagnosed by IOUS was palpable, and they were all extremely small--ranging from 4 x 6 to 12 x 16 mm. Seventy-three locations were examined in order to…
Impact of perioperative transfusions and sepsis on long-term oncologic outcomes after curative colon cancer resection. A retrospective analysis of a …
2020
Objective: Intra-abdominal septic complications (IASC) affect short-term outcomes after surgery for colon cancer. Blood transfusions have been associated with worse short-term results.The role of IASC and blood transfusions on long-term oncologic results is still debated. This study aims to assess the impact of these two variables on survival after curative colon cancer resection. Patients and methods: Retrospective analysis of a prospectively maintained database of patients who underwent curative surgery for colon cancer at a university hospital, between 1993 and 2010. Cox regression was used to identify the role of IASC and transfusions (alone and combined) on local recurrence (LR), disea…
Secondary technical resectability of colorectal cancer liver metastases after chemotherapy with or without selective internal radiotherapy in the ran…
2019
Background: Secondary resection of initially unresectable colorectal cancer liver metastases (CRLM) can prolong survival. The added value of selective internal radiotherapy (SIRT) to downsize lesions for resection is not known. This study evaluated the change in technical resectability of CRLM with the addition of SIRT to FOLFOX-based chemotherapy. Methods: Baseline and follow-up hepatic imaging of patients who received modified FOLFOX (mFOLFOX6: fluorouracil, leucovorin, oxaliplatin) chemotherapy with or without bevacizumab (control arm) versus mFOLFOX6 (with or without bevacizumab) plus SIRT using yttrium-90 resin microspheres (SIRT arm) in the phase III SIRFLOX trial were reviewed by thr…
