Femoral trabecular-pattern index and bone mineral content measurement by photon absorption in senile osteoporosis.

A comparative study of the usefulness of the femoral trabecular-pattern index (Singh index) and bone mineral content measurement by photon absorption in senile osteoporosis was performed in 106 white women, seventy to ninety-five years old. In 17% of the subjects adequate hip roentgenograms could not be obtained. Interpretation of the Singh index was not found to be simple and easily reproducible. A positive correlation was noted between the bone mineral content and the Singh index. The incidence of previous vertebral and non-vertebral fracture was noted to be inversely related to both bone mineral content and the Singh index, but neither method clearly separated subjects with fracture from those without fracture.

High frequency ventilator therapy for newborns.

High-frequency ventilation is a general term that refers to a family of ventilator techniques that utilize respirator rates greater than 60 breaths/minute and tidal volumes that are usually less than or equal to the anatomical dead space of the airways. These techniques include high frequency positive-pressure ventilation, high frequency jet ventilation, high frequency flow interruption, high frequency oscillatory ventilation, and high frequency chest wall oscillation. I review the proposed mechanisms of gas transport during high-frequency ventilation and the different ventilators capable of delivering this mode of ventilation. In addition, clinical studies involving infants treated with this new technology are reviewed, along with long-term patient follow-up and reported complications.

An HMO neonatology service. Providing care to high-risk newborns.

Clinical and technological advances in the treatment of premature infants and other acutely ill newborns have resulted in widespread use of neonatal intensive care units (NICUs). Along with this trend is concern over the high cost of NICU services. This paper describes how an HMO established a neonatology service in order to participate more directly in the care of its member infants and control the escalating costs of NICU therapy. Two years of NICU utilization data are presented. It is concluded that establishing a neonatology service within a managed care system can improve the clinical care of member neonates and decrease NICU costs.
