Abstract: Health-risk appraisals (HRAs) are self-scored questionnaires or computer programs that use demographic and risk-factor data to estimate the most likely causes of death and to provide guidance on how to reduce risk of death. The clinical usefulness of HRAs lies in their ability to motivate patients to modify negative habits and lifestyles. Still very much in a developmental stage, HRAs are not substitutes for preventive health examinations and are best used in conjunction with ongoing physician-supervised health-promotion and disease-prevention efforts.

Abstract: A bulky compression dressing (the Robert Jones bandage) is often used by orthopaedic surgeons. We have reviewed its history and monitored intramuscular compartment pressure under it after total knee replacement. We found that it increased compartment pressure and helped to reduce bleeding, tissue oedema and the size of effusions and haemarthroses.

Abstract: Patient perception of uterine activity was assessed objectively in 44 women at risk for preterm labor using a tocodynamometer designed for ambulatory outpatient use. The monitor allowed patient-activated marking of the data whenever contractions were perceived. After instruction in self-detection of uterine activity, tocodynamometry was performed daily for 8.5 weeks per patient. Patients identified an average of 15% of their contractions during the study (range 0-78%). Numerous marks were placed in the absence of any detectable uterine activity. Of multiple obstetric variables analyzed, only multifetal gestation and preterm labor in the current pregnancy had any significant impact on perception. Results suggest that self-detection of uterine activity may not be reliable as the only means for the earliest possible detection of preterm labor.
