Because parvovirus B19 infection during pregnancy has been associated with increased risk of fetal loss in small or selected study populations, the authors evaluated the risk in a population-based study. A nested casecontrol study was conducted by using a population-based screening for syphilis in 3 regions in Denmark from 1992 to 1994. Cases of women with fetal loss were identified in the Nati...
Over 1 million child fatalities occur per year, the bulk of them in less-developed countries. There remains a need, from country to country, to identify personal and environmental risk factors correlated with this mortality. The present study focused on Pakistan, home to a sizeable pediatric population of 60 million. The study employed case-control methods (i) to identify situational risk facto...
OBJECTIVE Pituitary autoimmunity is often found in association with other endocrine autoimmune or non-autoimmune diseases. Aim of the study was to assess the prevalence of serum pituitary antibodies (PitAb) in patients with Type 1 diabetes mellitus (T1DM) or Type 2 diabetes mellitus (T2DM). RESEARCH DESIGN AND METHODS In this casecontrol study 111 patients with T1DM, 110 patients with T2DM, a...
Although several genes have been implicated in the development of the early-onset autosomal dominant form of Alzheimer's disease (AD), the genetics of late-onset AD (LOAD) is complex. Loci on several chromosomes have been linked to the disease, but so far only the apolipoprotein E gene has been consistently shown to be a risk factor. We have performed a large-scale single-nucleotide polymorphis...
Hematologic malignancies are a heterogeneous group of conditions with an unclear etiology. We hypothesized that diabetes mellitus type 2 is associated with increased risk of developing lymphoma, leukemia, and myeloma. A literature search identified 26 studies (13 casecontrol and 13 cohort studies) evaluating such an association. Outcome was calculated as the odds ratio (OR) using a random effec...
Background: Use of exfoliative cytology and cyto-analysis is a useful early diagnostic method for epithelial atypia and for human oral neoplasm. A rare occurrence of cytological atypia appeared to be anuran tadpole larva, named as keratinized tadpole cell (KTC) is analyzed cytomorphometrically with a cytodiagnostic approach. Materials and Methods: In a casecontrol study, exfoliated scraped cyto...
BACKGROUND Hearing loss is a common and considerable disability that harms educational performance of school children in developing countries like Iran. Lack of a simple and practical screening protocol often deters routine and systematic hearing screening at school entry. METHODS This study was to establish a practical screening model for hearing loss in school-aged children based on a commu...
Noting a negative correlation between average radon levels and lung cancer mortality in Montana counties, Hart (2011) “questions the notion that radon is deadly in Montana.” Results from a much larger ecological study of the correlation between county radon levels and lung cancer mortality across the whole United States were published in the 1990s (Cohen 1990, 1995). Like Hart, Cohen found an i...
As early as 1910, it was observed in Paris, France, that about 80% of patients with cancer of the oesophagus and cardiac region of the stomach were alcoholics, who drank mainly absinthe (Lamy, 1910). ln the first half of this century, it was also noted from mortality statistics in various countries that high risks for cancers of the oral cavity, pharynx, oesophagus and larynx occurred among per...
Objective: To evaluate the incremental cost of and health benefits attributable to medical nutrition therapy (MNT) for managed care members participating in an obesityrelated health management program. Design: Retrospective casecontrol. Methodology: Overweight or obese adult managed care members who utilized the MNT benefit (n=291) were matched, using propensity score matching, with similar ind...
