Recently, epidemiologic studies have shown that the lack of vitamin D levels may be associated with high asthma prevalence, but its effect is still controversial, depending on season, area, and food consumption. We aimed to examine the association of serum vitamin D levels with the prevalence of pediatric asthma in Korea. A total of 80 children (50 asthmatic children and 30 healthy controls) aged 6-14 years were participated in this study. Serum 25-hydroxy vitamin D (vitamin D) levels were measured and compared between the two groups...

Objective: To understand the epidemiological characteristics and influencing factors related to HBeAg sero-clearance in chronic hepatitis B patients so as to provide evidence for regular management on chronic HBV patients. Methods: From 2012 to 2014, a cohort study was conducted among HBeAg positive chronic HBV patients in Jiangsu province. Association between the characteristics and incidence of HBeAg sero-clearance was analyzed by Cox regression method. The changing trend on HBV DNA between patients with HBeAg sero-clearance and those with persistent HBeAg positive status was compared by repeated measure data variance analysis method...

BACKGROUND: In aging populations with an ever-growing burden of risk factors such as obesity, diabetes, and hypertension, chronic kidney disease (CKD) is on the rise. However, little is known about its exact prevalence among elderly adults, and often albuminuria is not included in the definition of CKD. Moreover, novel equations for the estimated glomerular filtration rate (eGFR) have recently emerged, which have not been applied comprehensively to older adults. Data on CKD awareness among the elderly are sparse...

We performed a retrospective review of all patients with malignant otitis externa (MOE) treated in our center between July 2004 and December 2012 to evaluate the current epidemiology in our region and to ascertain causative factors associated with the perceived increase in the number of cases diagnosed. Eleven patients were identified (5 men and 6 women), with a mean age of 77 years (range: 38 to 97 years). Diabetes was present in 36%. Pseudomonas aeruginosa was the causative organism in 64% of cases; all pathogens were sensitive to ciprofloxacin...

: The study presents the updated data on the multiple myeloma (MM) incidence in Ukrainian cleanup workers after the Chornobyl accident and their survival. The epidemiological analysis is based on the extended follow-up period to identify new MM cases for higher statistical power and to collect additional data on the disease course and outcome for the survival analysis. The objective of the study was to analyze the MM incidence and survival in Chornobyl cleanup workers in 1996-2013 in comparison with the national MM statistical data...

: The epidemiology of pediatric acute osteomyelitis in the USA, such as annual hospitalization rates and disparities with respect to age, sex, race/ethnicity, and socioeconomic status, remains unknown. We obtained discharge records of hospitalized patients with acute osteomyelitis younger than 20 years of age from the Kids Inpatient Database for 2006, 2009, and 2012. We weighted the records to estimate the number of hospitalizations in the USA and calculated the annual rates of hospitalization because of acute osteomyelitis...

Between 2014 and 2015, the European Centre for Disease Prevention and Control was informed of an increase in numbers of Salmonella enterica serotype Chester cases with travel to Morocco occurring in six European countries. Epidemiological and microbiological investigations were conducted. In addition to gathering information on the characteristics of cases from the different countries in 2014, the epidemiological investigation comprised a matched case-case study involving French patients with salmonellosis who travelled to Morocco that year...

PURPOSE: A relationship of Epstein-Barr virus (EBV) and breast cancer etiology and outcome may have clinical utility and potential to enhance understanding of tumor biology. Research to date has yielded variable results, likely reflecting differing virus detection assays and unaddressed epidemiologic heterogeneity across studies. METHODS: Applying our novel, five-target assay detection strategy in an exploratory study, we examined demographic, clinical, and tumor characteristics, and overall survival, associated with EBV positivity in breast adenocarcinomas from 59 non-Hispanic white and 68 Hispanic women sampled by age (<50, 50+) and stage (localized, regional/remote) and examined associations based on single assay targets...

BACKGROUND: Hantaviruses cause two distinct human diseases: hemorrhagic fever with renal syndrome (HFRS) in Asia and Europe and hantavirus pulmonary syndrome (HPS) in America. In Europe, mainly Puumala, Dobrava and Seoul viruses cause HFRS. A total of 23 cases of HFRS were detected in Bulgaria over a 2‑year period 2013-2014. The aim of the study was to present epidemiology, clinical manifestations and laboratory findings of these patients. METHODS: Patients with HFRS were diagnosed using PCR, ELISA and immunoblotting tests...

INTRODUCTION: Myxomas are a group of benign rare tumors of connective-tissue origin that occur in both hard (central) and soft tissues of the body. The aim of this study is to highlight our experience in the management of central myxoma of the jaw, with emphasis on its clinic-epidemiologic features as seen in our environment. MATERIALS AND METHODS: All patients who were managed for central myxoma of the jaw at the Oral and Maxillofacial Surgery department of a regional University Teaching Hospital between September 1997 and October 2015 were retrospectively studied...

BACKGROUND: There is limited information about the challenges of cancer management and attempts at improving outcomes in Africa. Even though South and North Africa are better resourceds to tackle the burden of breast cancer, similar poor prognostic factors are common to all countries. The five-year overall Survival rate for breast cancer patients does not exceed 60% for any low and middle-income country (LMIC) in Africa. In spite of the gains achieved over the past decade, certain characteristics remain the same such as limited availability of breast conservation therapies, inadequate access to drugs, few oncology specialists and adherence to harmful socio-cultural practices...

BACKGROUND: Clinical trial results suggest that 5-alpha reductase inhibitors (5ARIs) for the treatment of benign prostatic hyperplasia (BPH) may increase the risk of gynecomastia and male breast cancer, but epidemiological studies have been limited. PATIENTS AND METHODS: We conducted a cohort study with nested case-control analyses using the UK Clinical Practice Research Datalink. We identified men diagnosed with BPH who were free from Klinefelter syndrome, prostate, genital or urinary cancer, prostatectomy or orchiectomy, or evidence of gynecomastia or breast cancer...

BACKGROUND: Anterior cruciate ligament (ACL) tears are thought to occur with increasing frequency in young patients. No study has shown increased incidence over time. We hypothesized the incidence of ACL tears in young patients has increased over the past 20 years. METHODS: This descriptive epidemiology study is a retrospective review of insurance billing data of all patients aged 6 to 18 years with Current Procedural Terminology, Fourth Revision codes for ACL tear and reconstruction or International Classification of Diseases, Ninth Revision, Clinical Modification codes from 1994 to 2013...

In recent years, there has been growing public awareness and increasing attention to young women with acute myocardial infarction (AMI), who represent an extreme phenotype. Young women presenting with AMI may develop coronary disease by different mechanisms and often have worse recoveries, with higher risk for morbidity and mortality compared with similarly aged men. The purpose of this cardiovascular perspective piece is to review recent studies of AMI in young women. More specifically, we emphasize differences in the epidemiology, diagnosis, and management of AMI in young women (when compared with men) across the continuum of care, including their pre-AMI, in-hospital, and post-AMI periods, and highlight gaps in knowledge and outcomes that can inform the next generation of research...

AIM: A national atrial fibrillation (AF) registry was conducted under the aegis of the Indian Heart Rhythm Society (IHRS), to capture epidemiological data-type of AF, clinical presentation and comorbidities, current treatment practices, and 1-year follow-up outcomes. METHODS: A total of 1537 patients were enrolled from 24 sites in India in the IHRS-AF registry from July 2011 to August 2012. Their baseline characteristics and follow-up data were recorded in case report forms and subsequently analyzed...
