Effects of residence and race on burden of travel for care: cross sectional analysis of the 2001 US National Household Travel Survey

Background  

Travel burden is a key element in conceptualizing geographic access to health care. Prior research has shown that both rural and minority populations bear disproportionate travel burdens. However, many studies are limited to specific types of patient or specific locales. The purpose of our study was to quantify geographic and race-based differences in distance traveled and time spent in travel for medical/dental care using representative national data.     

Determination of the conjunctival goblet cell density in 43 normal subjects

The goblet cell density in the nasai inferior fornical conjunctiva was determined in 43 normal subjects (57 eyes). The mean number of goblets per 100 epithelial cells was found to be 10.17 +/- 2.81 in the young averaging 25 years and 5.25 +/- 3.38 in the aged averaging 62 years (P less than 0.01). The relation between the morphological features of the epithelial cells and the number of goblet cells was discussed.     

Best evidence in critical care medicine Selective digestive decontamination decreases mortality and morbidity in the intensive care

SDD reduces ICU and in-hospital mortality, the length-of-stay in the ICU, the frequency of colonization with resistant GNB, and the total costs of antibiotic treatment. This supports the use of SDD in all patients expected to be on mechanical ventilation for at least two days in ICUs that have low prevalence of VRE and MRSA.     

Universal applications of sentinel node technology

The sentinel node (SN) concept was originally proposed by several pioneers in the middle of the last century. After Donald Morton and his colleagues demonstrated the clinical significance of the SN concept in melanoma, it attracted vast attention in surgical oncology. At recent international conferences, a number of new approaches in this field for various solid tumors have been reported. Now, there are several possible applications with different technological aspects, such as individualized surgical management of solid tumors, multidisciplinary treatments, and novel therapeutic approaches. This article provides an overview of the future potential of SN technology.
