This article presents a case of dental treatment in a patient with polycythemia vera. Polycythemia vera is an uncommon myeloproliferative disease that can have hematologic and surgical implications. The concerns and consequences of dental care in these patients are discussed and recommendations for dental treatment are given.
Forty-seven infants and children with tracheotomies were cared for at home for a follow-up period of 1,581 months. There were two relevant fatalities which gave a death rate of 0.13 deaths per 100 months. The average age at the time of tracheotomy was 13 months and the tracheotomy was in place for an average of 33 months per patient. The ability to care for these children was provided through coordinated, intensive training and a home-care program in which the inpatient nurse, nurse practitioner, social worker, pediatrician, and otorhinolaryngologist worked as a team.
This investigation compared the reliability and interchangeable use of three currently available goniometers--a universal goniometer, a fluid goniometer, and an electrogoniometer. Three consecutive readings of the active range of movement of the right elbow joint were taken from each of 23 healthy female volunteers; three experienced observers each used each type of goniometer on two occasions. A balanced experimental design was used to eliminate order effects with respect to subject, tester, or goniometer, and a rigid protocol was employed to reduce error due to diurnal or methodological variations. The results show that there are significant differences between the goniometers used, the testers, and the replications. Significant interaction effects also exist between the goniometers and the occasion, the goniometers and the testers, and the testers and replications. The data suggest that the interchangeable use of different types of goniometer in a clinical setting is inadvisable.
