RESUMEN

OBJECTIVE: To evaluate the effect driver-side and passenger-side airbags have had on the incidence and severity of maxillofacial trauma in victims of automobile accidents. DESIGN: Retrospective analysis of all automobile (passenger cars and light trucks) accidents reported in 1994. SETTING: New York State. PATIENTS: Of the 595910 individuals involved in motor vehicle accidents in New York in 1994, 377054 individuals were initially selected from accidents involving cars and light trucks. Of this subset, 164238 drivers and 62755 right front passengers were selected for analysis. MAIN OUTCOME MEASURES: Each case is described in a single record with approximately 100 variables describing the accident, eg, vehicle, safety equipment installed and utilized or deployed, occupant position, patient demographics, International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) diagnoses, and procedural treatments rendered. A maxillofacial trauma severity scale was devised, based on the ICD-9-CM diagnoses. RESULTS: Individuals using airbags and seat belts sustained facial injuries at a rate of 1 in 449, compared with a rate of 1 in 40 for individuals who did not use seat belts or airbags (P<.001). Those using airbags alone sustained facial injuries at the intermediate rate of 1 in 148, and victims using seat belts without airbags demonstrated an injury rate of 1 in 217 (P<.001). CONCLUSION: Use of driver-side airbags, when combined with use of seat belts, has resulted in a decrease in the incidence and severity of maxillofacial trauma.

RESUMEN

76 kidney transplant recipients who were up to 4 years post transplant, were studied to assess the incidence of secondary hyperparathyroidism. All patients had good renal function with a mean serum creatinine of 1.4 mg/100 ml. Secondary hyperparathyroidism, as evidenced by increased serum parathyroid hormone levels, was present in 53 of the 76 patients (66%) and radiologic bone disease in 26 of the 76 patients (34%), while hypercalcemia (serum calcium greater than 11.0 mg/100 ml) occurred in only 6 patients (8.5%). The incidence of secondary hyperparathyroidism decreased slightly with time following transplantation, but the degree of secondary hyperparathyroidism as indicated by the levels of serum parathyroid hormone at various times following renal transplantation was essentially similar. The causes for the persistence of this condition are not totally known, but it was found that its incidence was related to the duration of dialysis prior to transplantation.
