Permanent stenting in “unextractable” common bile duct stones in high risk patients. A prospective randomized study comparing two different stents
2007
BACKGROUND: Endoscopic sphincterotomy (ES) and stone extraction is the treatment of choice for bile duct stones. Therefore, if ES and conventional stone extraction fail, further treatment is mandatory. Insertion of a biliary endoprosthesis is an effective option. MATERIALS AND METHODS: We treated 30 high-risk patients (17 women and 13 men, mean age 82 years) affected by difficult common bile duct stones. The patients were randomly assigned preoperatively using closed envelopes (blind randomization) into two groups to receive insertion of polyethylene or hydrophilic hydromer-coated polyurethane stent, respectively. Follow-up was achieved by contacting referring physicians and patient's relat…
Recurrence of Acute Gallstone Pancreatitis and Relationship with Cholecystectomy or Endoscopic Sphincterotomy
2004
To determine the prevalence of recurrence of gallstone pancreatitis, its clinical features, and the presence of prognostic factors of recurrence.From January 1, 2000 to August 31, 2003, 233 patients admitted with acute gallstone pancreatitis (AGP) were prospectively studied. Patients were divided into two groups: recurrent and nonrecurrent group. Clinical, analytical, radiological, prognostic parameters, and severity (Atlanta criteria) were assessed, along with the performance of cholecystectomy or endoscopic sphincterotomy (ES). Clinical features of recurrence were analyzed. Univariate (chi(2), Student's t-test) and multivariate tests were performed. Statistical significance was assumed if…
Diabetes preceding Parkinson's disease onset. A case–control study
2009
Abstract Objective To assess the association between diabetes preceding Parkinson's disease (PD) and PD. Methods PD individuals were matched to PD free individuals randomly selected from people in the same municipality as the cases. Occurrence of diabetes preceding PD onset among cases and controls was assessed through a structured questionnaire. Information regarding current and past medical treatment and other variables was also collected. We used univariate and multivariate logistic models to calculate crude and adjusted odds ratios (OR). Covariates are adjusted for included education, smoking habit, alcohol and coffee consumption. Results 318 PD individuals (165 women, 153 men) and 318 …
Involvement of -308 TNF-alpha and 1267 Hsp70-2 polymorphisms and zinc status in the susceptibility of coronary artery disease (CAD) in old patients.
2006
Coronary artery disease (CAD) is characterized by an inflammatory status and it represents the major cause of death in elderly. Zinc deficiency and inflammatory genes within major histocompatibility complex (MHC) region are implicated in ischaemic heart diseases. TNF-alpha is present in coronary artery plaques and may provoke plaque instability. Hsp70 plays instead a pro-atherogenic role, via proinflammatory cytokine production, in atherosclerotic lesions contributing to plaque rupture. Contradictory data report the association between -308 TNF-alpha polymorphism and CAD, while no investigations exist on Hsp70-2 gene in CAD. In the current study, we analysed -308 TNF-alpha and 1267 Hsp70-2 …
Circulating Cell Adhesion Molecules and Death in Patients With Coronary Artery Disease
2001
Background —Vascular cell adhesion molecule (VCAM)-1, intercellular adhesion molecule (ICAM)-1, and E-selectin mediate adhesion and transmigration of leukocytes to the vascular endothelial wall and may promote plaque growth and instability. In a prospective study, we evaluated the effect of soluble adhesion molecules on the risk of future cardiovascular events among patients with angiographically documented coronary artery disease (CAD). Methods and Results —We obtained baseline samples from a prospective cohort of 1246 patients with CAD. Besides various markers of inflammation, soluble VCAM-1 (sVCAM-1), sICAM-1, and sE-selectin were determined. Follow-up information on cardiovascular even…
Correlation between leukocytosis and thrombosis in Philadelphia-negative chronic myeloproliferative neoplasms
2009
The evidence that leukocytes may contribute to the pathogenesis of thrombosis in Chronic Myeloproliferative Neoplasms is increasing but not definitive. To further enforces whether an increased leukocyte count is associated with thrombosis and whether this effect can be modulated by cytoreductive therapy, we analyzed the clinical course of 187 patients with Polycythemia Vera (PV) and Essential Thrombocythemia (ET) followed at two Italian Institutions over a period of 7 years. The association was measured at diagnosis or before thrombotic events: a multivariable analysis was carried out using data at baseline and time-dependent covariates. We found that white blood cells (WBC) count above 9.5…
Light exposure of the lower leg as a pathogenetic factor in the occurrence of malignant melanoma.
1992
Of the 1,198 women and men studied in Mainz from 1966 to 1987 there was an approximately fivefold increase in the incidence of melanoma. Among the men melanomas on the trunk (59.9%) predominated, whereas among the women melanomas on the extremities (40.0%) were more common, especially on the lower leg (26.3%). Comparing the decades 1966-1976 and 1977-1987 there was a significant decrease in melanomas affecting women's lower legs (1966-1976: 33%,; 1977-1987: 24.2%). Fashion-dependent sun exposure of this body area might offer an explanation. It could be demonstrated that common stocking materials do not sufficiently protect against UV radiation (average permeability for UV light about 55%), …
Immuno-inflammatory and thrombotic/fibrinolytic variables associated with acute ischemic stroke diagnosis.
2008
Abstract Introduction Accumulating evidence suggests that inflammation plays an important role in the development of acute cerebrovascular disease. The aim of this study is to evaluate the predictive value of a series of candidate serum immuno-inflammatory and thrombotic/fibrinolitic molecules towards diagnosis of acute ischemic stroke. Materials and methods We enrolled 120 consecutive patients with a diagnosis of acute ischemic stroke and 123 consecutive hospitalized control patients without a diagnosis of acute ischemic stroke. We evaluated plasma levels of IL-1β, TNF-β, IL-6 and IL-10, E-selectin, P-selectin, sICAM-1 and sVCAM-1 as markers of immuno-inflammatory activation, vWF plasma le…
Heart-type fatty acid binding protein is a sensitive biomarker for early AMI detection in troponin negative patients: a pilot study
2017
Background: Early detecting AMI in individuals presenting to the ED with chest pain continues to be a challenge. cTn is the gold standard for AMI diagnosis but early presenters (<1 hours from symptom onset) maybe cTn negative on admission. We analysed the diagnostic value of h-FABP and hs-TnI in patients presenting to ED with chest pain and no cTnI elevations. Methods: 28 AMI and 28 no-AMI individuals both presented to ED within one hour from pain onset were included. Blood donors were analysed for h-FABP cut-off identification. Among AMI patients, 55% were positive for h-FABP and 34.6% were positive for hs-TnI (p = .015), thus 21% were positive only for h-FABP. The diagnostic accuracy w…
More Likely to Dropout, but What if They Don’t? Partner Violence Offenders With Alcohol Abuse Problems Completing Batterer Intervention Programs
2018
There is general consensus that alcohol abuse is a risk factor to be considered in batterer intervention programs. Intimate partner violence perpetrators with alcohol abuse problems are more likely to dropout of batterer intervention programs. However, there is little research on intimate partner violence perpetrators with alcohol abuse problems completing batterer intervention programs. In this study, we analyze drop-out rates among perpetrators with alcohol abuse problems and explore whether perpetrators with alcohol abuse problems completing a batterer intervention program differ from those who do not have alcohol abuse problems in a number of outcomes. The sample was 286 males convicte…
