The effect of antibiotics during the perioperative period of percutaneous dilatational tracheostomy (PDT) is still controversial. A total of 297 patients who underwent the PDT procedure were divided into 2 groups:those administered antibiotics perioperatively and those not administered antibiotics. Wound infections were noted in 7 cases (incidence rate, 2.36%) and no death was recorded. Of the ...

OBJECTIVES The goal of this study was to describe acute occupational pesticide-related illnesses among youths and to provide prevention recommendations. METHODS Survey data from 8 states and from poison control center data were analyzed. Illness incidence rates and incidence rate ratios were calculated. RESULTS A total of 531 youths were identified with acute occupational pesticide-related ...

The current work adapts the optimal tree pruning algorithm(BFOS) introduced by Breiman et al.(1984) and extended by Chou et al.(1989) to the multi-document summarization task. BFOS algorithm is used to eliminate redundancy which is one of the main issues in multi-document summarization. Hierarchical Agglomerative Clustering algorithm(HAC) is employed to detect the redundancy. The tree designed ...

background: geographic differences in the incidence of cancers may suggest unique genetic or environmental exposures that impact the risk of acquiring cancer. this research aims to determine the incidence rate and geographical distribution of common cancers among iranian children. methods: in this ecological study, we extracted data that pertained to the incidence rate of common cancers among c...

Women who inject drugs have been shown to have higher incidence of HIV and risk behaviours than men, but there are conflicting reports about hepatitis C virus (HCV) incidence. We systematically reviewed the literature to examine the female-to-male (F:M) HCV incidence in female and male persons who inject drugs (PWID), and also to explore the heterogeneity (i.e. methodological diversity) in thes...

CONTEXT Few population-based studies have examined the incidence of meniscal injuries, and limited information is available on the influence of patient's demographic and occupational factors. OBJECTIVE To examine the incidence of meniscal injuries and the influence of demographic and occupational factors among active-duty US service members between 1998 and 2006. DESIGN Cohort study. SETT...

Maternal sun exposure in gestation and throughout the lifetime is necessary for vitamin D synthesis, and living near the sea is a population level index of seafood consumption. The aim of this study was to estimate the incidence rate of multiple sclerosis (MS) in Wales and examine its association with sun exposure, coastal living, and latitude. The study used a database of MS hospital visits an...

BACKGROUND Epidemiology of myocarditis in childhood is largely unknown. Men are known to have a higher incidence of myocarditis than women in adults aged <50 years, but whether this is true by sex in pediatric age groups is unknown. We set out to study the occurrence and potential sex differences of myocarditis in a general pediatric population. METHODS AND RESULTS Data of all hospital admiss...

The presence of silicon carbide (SiC) fibers in the SiC smelter work environment has suggested a possible cancer hazard. The authors studied cancer incidence among 2,620 men employed for more than 6 months in three Norwegian SiC smelters. Follow-up from 1953 to 1996 revealed an overall excess risk of lung cancer (standardized incidence ratio = 1.9, 95% confidence interval (CI): 1.5, 2.3) and an...
