Bacteremia after diagnostic conventional laparoscopy and minilaparoscopy: a prospective study in 100 patients.
2006
Background/Goals: Diagnostic laparoscopy under sedoanalgesia is a valuable tool in the work-up of liver diseases and is helpful as a staging procedure. The rate of bacteremia caused by this procedure is unknown, in particular when performed as minilaparoscopy. Study: A 100 consecutive patients having undergone diagnostic laparoscopy carried out either conventionally (group I, n = 50) or as minilaparoscopy (group II, n - 50) were prospectively enrolled in this study. Blood cultures were drawn before and within 5 minutes after the procedure. Risk factors for bacteremia were evaluated. Results: Bacterial growth occurred in 4 blood cultures drawn immediately after laparoscopy. No patient develo…
Kinetics of plasma biomarkers of inflammation and lung injury in surgical patients with or without postoperative pulmonary complications
2017
Background Postoperative pulmonary complications (PPCs) are common after major abdominal surgery. The kinetics of plasma biomarkers could improve identification of patients developing PPCs, but the kinetics may depend on intraoperative ventilator settings. Objective To test whether the kinetics of plasma biomarkers are capable of identifying patients who will develop PPCs, and whether the kinetics depend on the intraoperative level of positive end-expiratory pressure (PEEP). Design A preplanned substudy of a randomised controlled trial. Setting Operation room of five centres. Patients Two hundred and forty-two adult patients scheduled for abdominal surgery at risk of developing PPCs. Interv…
Coronary calcium score and computed tomography coronary angiography in high-risk asymptomatic subjects: assessment of diagnostic accuracy and prevale…
2010
The aim of the study was to compare the coronary artery calcium score (CACS) and computed tomography coronary angiography (CTCA) for the assessment of non-obstructive/obstructive coronary artery disease (CAD) in high-risk asymptomatic subjects. Two hundred and thirteen consecutive asymptomatic subjects (113 male; mean age 53.6 +/- 12.4 years) with more than one risk factor and an inconclusive or unfeasible non-invasive stress test result underwent CACS and CTCA in an outpatient setting. All patients underwent conventional coronary angiography (CAG). Data from CACS (threshold for positive image: Agatston score 1/100/1,000) and CTCA were compared with CAG regarding the degree of CAD (non-obst…
Clinical Epidemiological Survey of Legionella pneumophila Infections in Italy
1986
A clinical epidemiological survey of Legionella pneumophila infections occurring in Italy between 1 December 1985 and 31 May 1986 was carried out to evaluate the incidence of sporadic, epidemic and nosocomial L. pneumophila pneumonia. A total of 355 cases of pneumonia were studied of which 11.5% were due to Gram positive bacteria, 11% were due to Gram negative bacteria, 7.9% were due to Mycoplasma pneumoniae, 4.5% were due to L. pneumophila and 8.5% were due to sundry aetiological agents. The remainder (45.6%) could not be diagnosed accurately. In addition, the anti L. pneumophila antibody titres were assessed. The results are discussed in terms of the occurrence of the disease in Italy an…
Differential association of default mode network connectivity and rumination in healthy individuals and remitted MDD patients
2016
Rumination is associated with increased default-mode network (DMN) activity and functional connectivity (FC) in depressed and healthy individuals. In this study, we sought to examine the relationship between self-reported rumination and resting-state FC in the DMN and cognitive control networks in 25 remitted depressed patients and 25 matched healthy controls using independent component and seed-based analyses. We also explored potential group differences in the global pattern of resting-state FC. Healthy subjects with increased levels of rumination exhibited increased anterior DMN connectivity with the posterior DMN and the dorsal attention network and low connectivity within the anterior …
Prophylaxis of early bacterial infections after autologous peripheral blood stem cell transplantation (PBSCT): a matched-pair study comparing oral fl…
2005
The safety and efficacy of early bacterial prophylaxis with piperacillin-tazobactam were prospectively evaluated in 51 autologous peripheral blood stem cell transplantation (PBSCT) recipients. The results were compared with those obtained in 51 control patients receiving oral fluoroquinolones in a retrospective matched-pair control study. Overall, 76% of the study group and 98% of the control group developed at least one febrile episode during neutropenia (P=0.002). Time from neutropenia to the first febrile episode (FFE) was significantly longer in the study group than in the control group (P=0.04). Once a febrile episode appeared, the duration of fever was significantly longer in cases th…
Odontostomatological therapeutic possibilities in patients with sleep apnea
2009
Objectives: To evaluate the different therapeutic possibilities for treating Sleep Apnea/ Hypoapnea Syndrome (SAHS), as well as the effectiveness of such treatments, and to evaluate the epidemiological and clinical aspects of this syndrome. Study design: We carried out a meta-analytical, observational and retrospective study by selecting a total of 13 articles, which provided a sample size of 642 diagnosed cases of SAHS. Results: SAHS was more prevalent among males (88.7%) and the average age of diagnosis was 49.75 years old. In the majority of cases, these patients were found to be overweight, with an average body mass index of 28.32 Kg/ m². The average apnea / hypoapnea index was 31.64 ap…
Depression during an acute episode of schizophrenia or schizophreniform disorder and its impact on treatment response
2008
The aim of the present study was to examine the relevance of depressive symptoms during an acute schizophrenic episode for the prediction of treatment response. Two hundred inpatients who fulfilled DSM-IV criteria for schizophrenia or schizophreniform disorders were assessed at hospital admission and after 6 weeks of inpatient treatment using the Positive and Negative Syndrome Scale (PANSS) and the Hamilton Rating Scale for Depression (HAM-D). Depressive symptoms showed positive correlations with both positive and negative symptoms at admission and after 6 weeks, and decreased during 6 weeks of treatment. Pronounced depressive symptoms (HAM-D score> or =16) were found in 28% of the sample a…
Gender-specific associations of depression with positive and negative symptoms in acute schizophrenia
2006
This clinical study analyzed gender-specific relationships of depression with other psychopathological and clinical variables in hospitalized patients with schizophrenia. During clinical routine treatment 119 inpatients with acute schizophrenia (DSM-IV) were investigated with the Calgary Depression Rating Scale for Schizophrenia (CDSS), the Clinical Global Impressions (CGI), and the Positive and Negative Syndrome Scale (PANSS). Depression scores of 77 male and 42 female patients (mean age 31.6+/-10.3 years) were related to background variables and to positive and negative symptom scores. Mean CDSS (5.8+/-5.6) and PANSS scores (total 76.9+/-22.1, positive symptoms 17.6+/-7.6, negative sympto…
Vulnerability to psychotogenic effects of ketamine is associated with elevated D2/3-receptor availability.
2012
Previous positron emission tomography (PET) studies employing competition paradigms have shown either no change or substantial declines in striatal ( 11 C)-raclopride binding after challenge with psychotogenic doses of the N-methyl-D-aspartate antagonist ketamine. We sought to probe the relationship between the severity of ketamine-induced psychotic symptoms and altered dopamine D2/3 receptor availability throughout brain using the high affinity ligand ( 18 F)-fallypride (FP). PET recordings were obtained in a group of 10 healthy, young male volunteers, in a placebo condition, and in the course of an infusion with ketamine at a psychotomimetic dose. Administration of the Positive and Negati…
