Preliminary experience with the application of Gadolinium-DTPA before MR imaging-guided laser-induced interstitial thermotherapy of brain tumors
1997
The purpose of this study was to investigate the potential value of i.v. gadolinium-diethylenetriamine penta-acetic acid (Gd-DTPA) applied before MRI-guided laser-induced interstitial thermotherapy (LITT) of brain tumors without original enhancement, especially in defining total lesion size during therapy. MRI-guided LITT was performed on two patients with astrocytoma WHO II. For both patients, Gd-DTPA was administered intravenously after a first irradiation period and LITT was continued after pulling back the light guide to coagulate the upper parts of the tumor. In both patients, the whole irreversible damaged zone of the second irradiation period after Gd-DTPA showed an intense increase …
Atrial fibrillation management: A prospective survey in ESC Member Countries - The Euro Heart Survey on atrial fibrillation
2005
Aims To describe atrial fibrillation (AF) management in member countries of the European Society of Cardiology (ESC) and to verify cardiology practices against guidelines. Methods and results Among 182 hospitals in 35 countries, 5333 ambulant and hospitalized AF patients were enrolled, in 2003 and 2004. AF was primary or secondary diagnosis, and was confirmed on ECG in the preceding 12 months. Clinical type of AF was reported to be first detected in 978, paroxysmal in 1517, persistent in 1167, and permanent in 1547 patients. Concomitant diseases were present in 90% of all patients, causing risk factors for stroke to be also highly prevalent (86%). As many as 69% of patients were symptomatic…
Clinical Predictors for Poor Quality of Life in Patients With Covert Hepatic Encephalopathy.
2018
Background Current EASL/AASLD guidelines recommend treatment of covert hepatic encephalopathy (HE) only in symptomatic patients, for example, in those with impaired quality of life or with affected driving abilities. Goals Because testing for impaired quality of life is time consuming, the aim of the present study was to identify simple clinical predictors for poor quality of life in patients with covert HE (CHE). Study In total, 139 cirrhotic in- and outpatients without a history of overt hepatic encephalopathy were enrolled. Diagnosis of HE grade 1 (HE1) was diagnosed clinically according to the West-Haven Criteria. Critical flicker frequency and the Psychometric Hepatic Encephalopathy Sc…
The WHO guidelines for chronic hepatitis B fail to detect half of the patients in need of treatment in Ethiopia
2019
Background & Aims In 2015, the World Health Organization (WHO) issued guidelines for the management of chronic hepatitis B (CHB) in low- and middle-income countries, but little is known about the applicability of the WHO treatment criteria in sub-Saharan Africa. The aim of this study was to evaluate the diagnostic performance of the WHO guidelines in a large CHB cohort in Ethiopia. Methods Treatment-naive adults who attended a public CHB clinic in Addis Ababa were included in this analysis. All patients underwent a standardized evaluation at recruitment, including blood tests and transient elastography (Fibroscan®). A Fibroscan result >7.9 kPa was used to define significant fibrosis and >9.…
Diagnosis, treatment and long-term outcomes of autoimmune pancreatitis in Spain based on the International Consensus Diagnostic Criteria: A multi-cen…
2015
Abstract Objectives Autoimmune pancreatitis (AIP) is a form of chronic pancreatitis that has been reported worldwide for the last two decades. The aim of this study is to analyse the clinical profile of patients from Spain with AIP, as well as treatments, relapses and long-term outcomes. Methods Data from 59 patients with suspected AIP that had been diagnosed in 15 institutions are retrospectively analysed. Subjects are classified according to the International Consensus Diagnostic Criteria (ICDC). Patients with type 1 AIP (AIP1) and type 2 AIP (AIP2) are compared. Kaplan–Meier methodology is used to estimate the overall survival without relapses. Results Fifty-two patients met ICDC, 45 pat…
[Appropriate cytotoxic drug usages in solid tumors: conformity to official labelling and level of scientific evidence]
2006
International audience; The definition of appropriate use of drugs is questioned in oncology. Daily therapeutic practices were compared to official labelling and to published scientific data in this retrospective study. It was carried out in two respective specialised centers, from January to September 2004. All chemotherapies administered for adult solid tumours and including one of the eleven studied drugs were evaluated. The analysis of use was performed by drug : conformity to the validated labelling and level of scientific evidence (at the period study). The study included 1,561 drug uses in 1,211 patients. The overall rate of conformity to official labelling was 81.7 % (67.1 % of stri…
How do international gastric cancer prevention guidelines influence clinical practice globally?
2020
Clinical guidelines recommend particular approaches, including 'screen-and-treat' strategy for Helicobacter pylori, to prevent gastric cancer. However, little of this is implemented in clinical practice. The aim of the study was to identify barriers to implementation of international guidelines. A web-based questionnaire distributed globally to specialists in the field. Altogether 886 responses from 75 countries were received. Of the responders, 570 (64%) were men of mean age 47 years. There were 606 gastroenterologists and 65 epidemiologists among the responders. Altogether, 79.8% of the responders disagreed that the burden of gastric cancer is a diminishing problem. 'Screen-and-treat' str…
Implication of the Examining Pathologist to Meet the Oncologic Standard of Lymph Node Count after Laparoscopic Lymphadenectomy
2010
<i>Objective:</i> The lymph node number as benchmark in oncologic operations depends on the patient’s anatomy, surgeon’s skill and pathologist’s accuracy. The influence of the pathologist is barely evaluated. <i>Methods:</i> A retrospective analysis of lymph node numbers after 700 laparoscopic lymphadenectomies in correlation to the examining pathologists was done. Three surgeons from the same department performed all operations at 2 campi, where 2 separate pathology institutions exist. Lymph node specimens were assigned randomly to any of the 62 involved pathologists. <i>Results:</i> The mean number of lymph nodes was equal for all surgeons. Lymph node s…
Changes in cerebellar activation pattern during two successive sequences of saccades
2002
The changes in the cerebellar activation pattern of two successive fMRI scanning runs were determined for visually guided to‐and‐fro saccades in 12 healthy volunteers familiar with the study paradigm. Group and single subject‐analyses revealed a constant activation of the paramedian cerebellar vermis (uvula, tonsils, tuber, folium/declive), which reflects constant ocular motor activity in both runs. A significant decrease in activation of the cerebellar hemispheres found in the second run is best explained by either a decrease in attention or the effects of motor optimization and learning. The significant, systematic changes of the cerebellar activation pattern in two successive runs were n…
The use of proton pump inhibitors in an Italian hospital: focus on oncologic and critical non-ICU patients
2015
Background Proton pump inhibitors (PPIs) are among the most misused drugs both at the community and hospital level. Recently, possible risks have been underscored, suggesting the importance of limiting PPI use to proven indications. Objective To survey the appropriateness of PPI use in a University hospital in Italy. Setting Azienda Ospedaliera Universitaria Policlinico ‘P. Giaccone’, in Palermo, Italy. Method A one day-observational study, reviewing patients’ medical records to identify treatments with PPIs and the indications for their use. After discharge, a subgroup of the cohort was followed up to assess the continuation of therapy at home. Appropriateness was evaluated according to th…
