Randomized Controlled Trial Comparative Study Clinical Trial
Caller satisfaction with after-hours telephone advice: nurse advice service versus on-call pediatricians.
To compare caller satisfaction with after-hours medical advice provided by a for-profit nurse advice service with advice provided by on-call pediatricians. ⋯ Callers were less satisfied with medical advice provided by a nurse advice service compared with the traditional on-call pediatrician. The lower satisfaction was associated with somewhat poorer compliance with recommended triage dispositions and more frequent repeat calls for medical advice.

Randomized Controlled Trial Comparative Study Clinical Trial
Asthma management and environmental tobacco smoke exposure reduction in Latino children: a controlled trial.
This study tested the efficacy of coaching to reduce environmental tobacco smoke (ETS) exposure among asthmatic Latino children. ⋯ Asthma management education plus coaching can reduce ETS exposure more than expected from education alone, and decreases in the coached condition may be sustained for about a year. The delayed decrease in cotinine among controls is discussed.

Sudden infant death syndrome (SIDS) victims were regarded as normal as a matter of definition (Beckwith 1970) until 1952 when Kinney and colleagues argued for elimination of the clause, "unexpected by history." They argued that "not all SIDS victims were normal," and referred to their hypothesis that SIDS results from brain abnormalities, which they postulated "to originate in utero and lead to sudden death during a vulnerable postnatal period." Bergman (1970) argued that SIDS did not depend on any "single characteristic that ordains a infant for death," but on an interaction of risk factors with variable probabilities. Wedgwood (1972) agreed and grouped risk factors into the first "triple risk hypothesis" consisting of general vulnerability, age-specific risks, and precipitating factors. Raring (1975), based on a bell-shaped curve of age of death (log-transformed), concluded that SIDS was a random process with multifactorial causation. ⋯ This is in contrast to the delay until the postneonatal period of most SIDS deaths. A categorical statement that the origin of SIDS is prenatal is unwarranted by the evidence. Brainstem abnormalities have not been shown to cause SIDS, but are more likely a nonspecific effect of hypoxia.

Practice Guideline Guideline
Guidelines for the prevention of intravascular catheter-related infections. The Hospital Infection Control Practices Advisory Committee, Center for Disease Control and Prevention, U.S.
These guidelines have been developed for practitioners who insert catheters and for persons responsible for surveillance and control of infections in hospital, outpatient, and home health-care settings. This report was prepared by a working group comprising members from professional organizations representing the disciplines of critical care medicine, infectious diseases, health-care infection control, surgery, anesthesiology, interventional radiology, pulmonary medicine, pediatric medicine, and nursing. ⋯ Major areas of emphasis include 1) educating and training health-care providers who insert and maintain catheters; 2) using maximal sterile barrier precautions during central venous catheter insertion; 3) using a 2% chlorhexidine preparation for skin antisepsis; 4) avoiding routine replacement of central venous catheters as a strategy to prevent infection; and 5) using antiseptic/antibiotic impregnated short-term central venous catheters if the rate of infection is high despite adherence to other strategies (ie, education and training, maximal sterile barrier precautions, and 2% chlorhexidine for skin antisepsis). These guidelines also identify performance indicators that can be used locally by health-care institutions or organizations to monitor their success in implementing these evidence-based recommendations.

Comparative Study
Discrepancies between direct and indirect blood pressure measurements using various recommendations for arm cuff selection.
The current recommendation for choosing an appropriate size cuff for measuring blood pressure (BP) is a bladder width to equal 40% of the upper arm circumference (UAC). However, most physicians use the older two-thirds or three-fourths upper arm length (UAL) recommendations to choose a cuff. The aim of this study was to verify the disparity in cuff size by using two-thirds UAL, three-fourths UAL, and 40% UAC criteria for cuff selection and to compare the indirectly measured BP by these criteria with directly measured radial intra-arterial BP. ⋯ Practitioners are likely to use significantly larger arm cuffs when following the two-thirds and three-fourths UAL criteria than when following the 40% UAC criterion. Of the 3 criteria for cuff selection, systolic BP by 40% UAC criterion most accurately reflects directly measured radial arterial pressure. However, the 40% UAC cuff significantly overestimates the diastolic pressure. Using available cuffs for indirect measurements by two-thirds and three-quarters UAL criteria significantly underestimates systolic as well as diastolic BP when compared with radial intra-arterial BP.
