Indirect measures that determine the number of reconstructive urologists in the US seem to indicate a general shortage in the number of these specially trained surgeons. This shortage may worsen in the future, as the US population continues to age and the number of urologists relative to the general population growth continues to fall. The lack of reconstructive urology expertise seems to drive...

Sonography is an attractive supplement to mammography in breast cancer screening because it is relatively inexpensive, requires no contrast-medium injection, is well tolerated by patients, and is widely available for equipment as compared with MRI. Sonography has been especially valuable for women with mammographically dense breast because it has consistently been able to detect a substantial n...

BACKGROUND AND PURPOSE Screening for dysphagia is essential to the implementation of preventive therapies for patients with stroke. A systematic review was undertaken to determine the evidence-based validity of dysphagia screening items using instrumental evaluation as the reference standard. METHODS Four databases from 1985 through March 2011 were searched using the terms cerebrovascular dis...

This document describes the Network Time Protocol (NTP), specifies its formal structure and summarizes information useful for its implementation. NTP provides the mechanisms to synchronize time and coordinate time distribution in a large, diverse internet operating at rates from mundane to lightwave. It uses a returnable-time design in which a distributed subnet of time servers operating in a s...

BACKGROUND There is growing interest in clinical screening for pediatric social determinants of health, but little evidence on formats that maximize disclosure rates on a wide range of potentially sensitive topics. We designed a study to examine disclosure rates and hypothesized that there would be no difference in disclosure rates on face-to-face versus electronic screening formats for items o...

BACKGROUND This study examines variations in breast cancer screening among primary care clinicians by geographic location of clinical practice. METHODS A cross-sectional survey design was used to examine approaches to breast cancer screening among physicians, nurse practitioners, and physician assistants involved in primary care practice. A summary index of beliefs about breast cancer screeni...
