Heterotopic bone formation in patients with DISH following total hip replacement

Radiographs of 236 patients who underwent total hip replacement (THR) were evaluated for heterotopic bone formation. There was no significant difference in the presence and degree of ossification in patients with and without diffuse idiopathic skeletal hyperostosis (DISH). The authors conclude that DISH is not a significant risk factor in the development of heterotopic bone formation following THR.     

The Value of Undergraduate Electives for Recruitment in Psychiatric and Mental Health Nursing

The current nursing shortage has focused attention upon the need for the recruitment and retention of nursing students, as well as practitioners, to increase the available supply of nurses. Specialties such as psychiatric nursing which historically have not attracted a large percentage of graduates are at particular risk for nurse shortages. The nursing Literature of the past 15 years has demonstrated that undergraduate electives have served to interest students in particular areas of nursing. The experience of one baccalaureate nursing program which used a grant to institute electives for recruitment into employment and graduate study is described in this article.
