Post-traumatic myositis ossificans is a benign condition of heterotopic bone formation, which can mimic soft-tissue and bone malignancies. This pictorial review describes the specific imaging features of myositis ossificans using different imaging techniques, but with emphasis on MRI.
Approximately 20% of women in the United Kingdom have a hysterectomy by the age of 60 years for various reasons, usually a total hysterectomy. This modern hysterectomy was introduced in order to prevent the occurrence of cervical stump carcinoma. The incidence of cervical stump carcinoma is low and with the advent of Papanicolaou smears have been negligible. Many gynecologists and patients worldwide have questioned the routine removal of the benign cervix, as the argument for conserving the cervix is less disturbance to bladder, bowel and sexual function. This study was undertaken to review the long-term outcome after subtotal hysterectomy.
OBJECTIVE: To determine the effect of location within the hospital and preexisting electrocardiographic rhythm on the outcome of cardiopulmonary resuscitation, the cardiopulmonary resuscitation records for a 3-year period, including 668 hospitalized patients, were retrospectively reviewed. RESULTS: Resuscitation was successful in only 12 patients in the intensive care unit (3.3%) and 43 patients not in the intensive care unit (14.0%), 20 of whom were on a telemetry unit. Patients who survived to discharge had similar 1-year survival rates regardless of initial hospital location, although intensive care unit patients had the best 3-year survival rate, and there were no survivors at 3-years in the group that received cardiopulmonary resuscitation in the nonmonitored hospital bed. Survival was best with an initial cardiac rhythm of ventricular tachycardia or fibrillation, but all non-ventricular tachyarrhythmias were associated with survival. Age was not an apparent factor, while survival to hospital discharge favored whites over blacks. CONCLUSIONS: Futile resuscitative efforts are routinely performed in part because physicians and patients are unaware of outcome results and factors that influence survival. A wider recognition of the limitations of cardiopulmonary resuscitation should lead to advanced directives that reflect this awareness, with substantially more patients choosing not to have cardiopulmonary resuscitation.
After institutional review defined an unacceptable mortality rate in nonoperative treatment of elderly patients with odontoid process fracture without neurological deficit, we undertook a prospective study to determine the influence of early surgical stabilization on perioperative mortality in geriatric odontoid process fracture patients without neurologic injury. Analysis suggests that acute perifracture mortality in this high-risk group can be significantly decreased and potentially eliminated by this approach.

The head and neck region is frequently involved by AIDS-related Kaposi's sarcoma, the oral cavity being the most common site of occurrence. We report on the first case of AIDS-related Kaposi's sarcoma involving the sphenoid sinus where radionuclide bone scanning and MRI were effective in suggesting the diagnosis.
