Risk of Non-Hodgkin Lymphoma in Celiac Disease
2002
CONTEXT: Celiac disease is one of the most common lifelong disorders. Non-Hodgkin lymphoma is a possible complication of celiac disease and may lead to a large portion of lymphoma cases. OBJECTIVE: To quantify the risk for developing non-Hodgkin lymphoma of any primary site associated with celiac disease. DESIGN AND SETTING: Multicenter, case-control study conducted between January 1996 and December 1999 throughout Italy. PATIENTS: Cases were older than 20 years (median, 57; range, 20-92 years) with non-Hodgkin lymphoma of any primary site and histological type and were recruited at the time of the diagnosis. Controls were healthy adults (2739 men and 2981 women) from the general population…
Pulse pressure amplification and its determinants
2015
Background. Pulse pressure (PP) amplification expressed as the peripheral-to-central PP ratio has gained importance in the assessment of cardiovascular phenotypes and cardiovascular risk. The aim of the present study was to assess the relationship between PP amplification, large vessel parameters and peripheral blood pressure (BP) to gain insights into the amplification phenomenon. Methods. Peripheral BP, central BP and carotid-femoral pulse wave velocity (cfPWV) were assessed using the OMRON M6, SphygmoCor and Complior devices, respectively, in 741 adults attending the hypertension outpatient clinic. Analysis of covariance, partial correlations and multiple linear regression models were pe…
A pooled analysis of cigarette smoking and risk of multiple myeloma from the international multiple myeloma consortium.
2015
Abstract Background: Past investigations of cigarette smoking and multiple myeloma have been underpowered to detect moderate associations, particularly within subgroups. To clarify this association, we conducted a pooled analysis of nine case–control studies in the International Multiple Myeloma Consortium, with individual-level questionnaire data on cigarette smoking history and other covariates. Methods: Using a pooled population of 2,670 cases and 11,913 controls, we computed odds ratios (OR) and 95% confidence intervals (CI) relating smoking to multiple myeloma risk using unconditional logistic regression adjusting for gender, age group, race, education, body mass index, alcohol consump…
Morphometric assessment of testicular changes in drug-related fatalities.
2000
Testicular sections of 50 deceased drug addicts were examined by light microscopy using morphometric methods and determining the extent of spermatogenesis by application of the Johnsen score count. Twenty cases of violent death served as reference sample. The study was aimed at obtaining data about the degree of germinal gland damage following the duration of the individual drug career, which was correlated to the histologic findings. Progressively reduced maturation of germinal cells, decrease of tubular diameter and height of sperm-producing epithelium were found the longer the individual case history has been. The results clearly indicated a substantial impairment of male fertility in th…
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…
Farm-related exposures and childhood brain tumours in seven countries: results from the SEARCH International Brain Tumour Study.
2003
A total of 1218 cases of childhood brain tumours (CBT) and 2223 control subjects from the general population were included in a population-based case-control study conducted in nine centres in seven countries. Mothers were asked about farm- or agriculture-related exposures. Significantly elevated odds ratios (OR) for CBT were associated with children's personal and maternal prenatal exposure while living on a farm with pigs (child OR = 1.7, mother OR = 2.3), horses (child OR = 1.6, mother OR = 1.8), dogs (child OR = 1.5, mother OR = 1.5) and cats (child OR = 1.5, mother OR = 1.7). Children who were exposed to pigs, horses and cats combined, while living on a farm, had a threefold elevated O…
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…
Mortality in the first 30 days following incident acute symptomatic seizures.
2005
Purpose: Very little is known about short-term mortality after acute symptomatic seizure. One study found an increased mortality in the first year after acute symptomatic seizure, like mortality following acute symptomatic status epilepticus. Methods: We studied mortality in the first 30 days after an acute symptomatic seizure in two cohorts. In Washington Heights, New York City, we reviewed the medical records of all adults aged 20 years and older seen at Columbia Presbyterian Medical Center from January 1, 1990 through December 13, 1994 to identify incident acute symptomatic seizure. In Rochester, Minnesota, the medical records of all Rochester residents were reviewed to identify incident…
Case report: acute portal vein thrombosis associated with acute cytomegalovirus infection in an immunocompetent adult
2017
Cytomegalovirus (CMV) infection is usually asymptomatic and self-limiting in healthy individuals, but significant complications can develop in immunosuppressed patients. Venous or arterial thromboembolic phenomena are uncommon yet very serious complications of CMV infection. Most published reports describe immunosuppressed patients, but thrombotic events in CMV-infected immunocompetent individuals may also occur. We describe the case of an immunocompetent young man with acute CMV hepatitis that was complicated with portal vein thrombosis (PVT). We also review the literature regarding the association between PVT and CMV in immunocompetent patients. Thromboembolism is an underestimated but si…
Temporal evolution of stress in the year prior to the onset of depressive disorders
1999
Abstract Background . We investigate how the stress levels in a sample of patients with depressive disorders vary in the year prior to the onset of symptoms. Design . Observational study of the case/control type. Fifty patients whose first depressive episode began in the 6 months prior to the interview Method . The LEDS was applied to all the subjects. A calculation was made of the evolution week by week of stress throughout the year prior to the onset. Results . Notable differences were detected in the temporal profile of the stress between the depressive patients and control groups. The differences between them were especially far-reaching in the 26 weeks prior to the onset of the symptom…
