Pattern and characteristics of advanced cancer patients admitted to hospices in Italy
2013
Abstract The aim of this multicenter study was to assess the pattern and the characteristics of advanced cancer patients admitted to hospices. A consecutive sample of patients admitted in a period of 6 months was taken into consideration. Two hundred thirty-six patients admitted to hospices were consecutively assessed. Ninety-six percent of patients were admitted in acute hospital in the previous 3 months, with a mean time spent in hospital of 34.5 days, and 47 % of patients had received chemotherapy the month before hospice admission. Thirty-four percent of patients for whom data were available had significant persistent pain, and 44 % of them presented episodes of breakthrough pain. Sixty…
Inflammatory Bowel Disease Phenotype as Risk Factor for Cancer in a Prospective Multicentre Nested Case-Control IG-IBD Study
2016
Background and Aims: Cancer risk in inflammatory bowel disease [IBD] is still debated. In a prospective, multicentre, nested case-control study, we aimed to characterise incident cases of cancer in IBD. The role of immunomodulators vs clinical characteristics of IBD as risk factors for cancer was also investigated. Materials and Methods: From January 2012 to December 2014, each IBD patient with incident cancer was matched with two IBD patients without cancer for: IBD type, gender, and age. Risk factors were assessed by multivariate regression analysis. Results: IBD patients considered numbered 44619: 21953 Crohn’s disease \[CD], 22666 ulcerative colitis [UC]. Cancer occurred in 174 patients…
Ultrasound detection of abdominal lymphadenomegaly in subjects with hepatitis C virus infection and persistently normal transaminases: a predictive i…
1998
The indications for liver biopsy in anti-HCV-positive patients with persistently normal alanine aminotransferase levels are not clearly established. Recent studies have correlated the presence of abdominal lymphoadenomegaly with disease severity in patients with chronic hepatitis C. Our study aimed to evaluate the frequency of abdominal lymphoadenomegaly in an anti-HCV positive blood donor population with persistently normal alanine aminotransferase and the relationship of abdominal lymphoadenomegaly with the severity of liver changes.Eighty-six anti-HCV positive blood donors (58 M, 28 F) with normal alanine aminotransferase were followed up for a median of 31 months (range 12-50). To evalu…
Clinicopathological analysis of 1571 cutaneous malignant melanomas in Valencia, Spain: factors related to tumour thickness.
2006
Epidemiological studies on cutaneous melanoma in Mediterranean countries are scarce. Our aim was to perform a descriptive analysis of melanoma cases diagnosed in Valencia, Spain, and to evaluate the relationship between Breslow thickness and some clinical features. A total of 1571 patients with histologically confirmed cutaneous malignant melanoma diagnosed at the two main referral melanoma centres were evaluated retrospectively. For each patient the following clinical and pathological characteristics were selected: age, gender, anatomic site, histogenetic type, Breslow thickness, presence of ulceration, the stage, and symptoms such as bleeding, changes in size and colour, altered sensation…
SEARCH international case-control study of childhood brain tumours: role of index pregnancy and birth, and mother's reproductive history.
1999
A series of co-ordinated population-based case-control studies of childhood brain tumours (CBT) was undertaken under the auspices of the Surveillance of Environmental Aspects Related to Cancer in Humans (SEARCH) programme of the International Agency for Research on Cancer (IARC) to evaluate, inter alia, the risk in relation to characteristics of the index pregnancy and birth, and maternal reproductive history. Subjects comprised 1218 cases aged 0-19 years and 2223 controls. Risk estimates were calculated by unconditional logistic regression, adjusted for age, sex, centre and mother's years of schooling, for all types of CBT combined as well as for four groups defined by histopathology (astr…
Influence of social factors on avoidable mortality: a hospital-based case-control study.
2005
Objective. The effect of socioeconomic factors on avoidable mortality at an individual level is not well known, since most studies showing this association are based on aggregate data. The purpose of this study was to determine socioeconomic differences between those patients who die of avoidable causes and those who do not die. Methods. A matched case-control study was carried out regarding in-hospital avoidable mortality (Holland's medical care indicators) that occurred in a university hospital serving a Spanish-Mediterranean population during a 30-month period. Results. We studied 82 cases of death from avoidable causes and 300 controls matched on medical care indicators and age. The var…

Occupational injuries of teachers and educational staff at special schools with multiple and severely handicapped children in Rhineland‐Palatinate (Germany): results of a cross‐sectional study: Matthias Claus, et al. Institute for Teachers’ Health at the University Medical Center of the Johannes Gutenberg University of Mainz, Germany OBJECTIVE: The present study aimed to describe the prevalence, type, and influencing factors of occupational injuries of staff working at special schools with multiple and severely handicapped pupils in Southwestern Germany. METHODS: This cross‐sectional study was carried out between August 2010 and August 2012 at 13 special schools with focus on motoric and/or…
Helicobacter pylori infection does not affect the early rebleeding rate in patients with peptic ulcer bleeding after successful endoscopic hemostasis…
2003
Background and study aims Eradication of Helicobacter pylori infection can reduce the rebleeding rate of peptic ulcer bleeding in the long term. There are few data on the influence of H. pylori on the rebleeding rate in the acute phase of bleeding however. We therefore prospectively investigated the influence of H. pylori infection on the early rebleeding rate in patients who had undergone successful endoscopic hemostasis treatment for peptic ulcer bleeding. Patients and methods Between January 1996 and November 2000 all patients with peptic ulcer bleeding were evaluated consecutively. The diagnosis of H. pylori infection was made at index endoscopy, using histology and the rapid urease tes…
Syncope in the German Nationwide inpatient sample – Syncope in atrial fibrillation/flutter is related to pulmonary embolism and is accompanied by hig…
2019
Syncope is a common phenomenon in the general population. Although most of the causes are of benign origin, some comorbidities are accompanied by high mortality. We aimed to compare the in-hospital mortality of patients with syncope related to different comorbities and investigate the impact of syncope in patients with atrial fibrillation/flutter (AF).The nationwide inpatient sample of Germany of the years 2011-2014 was used for this analysis. Patients with syncope (ICD-code R55) were stratified by presence of selected comorbidities. Additionally, AF patients with and without syncope were compared. Incidence of syncope and in-hospital mortality were calculated. Syncope as a predictor of adv…
Prevalence and risk factors of retinal vein occlusion: the Gutenberg Health Study.
2015
SummaryObjective To determine the age- and sex-specific prevalence and determinants of retinal vein occlusions (RVOs) in a large population-based German cohort. Methods The investigation included 15 010 participants (aged 35–74 years) from the Gutenberg Health Study. We determined the prevalence of RVO (central retinal vein occlusion [CRVO] and branch retinal vein occlusion [BRVO]) for the local population by assessing fundus photographs of 12 954 (86.3%; 49.8% women and 50.2% men) participants. Further, we analyzed the associations of RVO with cardiovascular, anthropometric, and ophthalmic parameters. Results The weighted prevalences of RVO, CRVO, and BRVO were 0.40%, 0.08%, and 0.32%, res…
