Abstract: A mandatory seatbelt use law, the first such law in the nation, became fully in force in New York State as of 1 January, 1985. We studied seatbelt use among drivers and front seat passengers involved in motor vehicle accidents for a 3-month period pre-legislation (Phase 1), and a 5-month period post-legislation (Phase 2), to determine if this type of compulsory law, providing civil fines of $50 for violators, changes seatbelt use behavior. The reported use rate among drivers rose from 21% pre-legislation to 47% post-legislation (p less than 0.01). The use rate among front seat passengers rose from 21% to 40% (not significantly different due to the small number of occupants recorded in this position). A highway survey (Phase 3) noted the use rate in New York City and surrounding counties to be 63%, a marked increase from the published pre-legislation value of 16%. We conclude that mandatory seatbelt use legislation is effective in significantly increasing seatbelt use and urge physicians to seek similar legislation in every state.

Abstract: Congenital cystic dilatation of the biliary tree (Caroli's disease) is a rare condition that usually presents with ascending cholangitis. This report demonstrates the difficulty of recognizing other complications of Caroli's disease antemortem. A 35-year-old man developed a subphrenic abscess and malignant transformation of the biliary tree; both were clinically undetected. Episodes of pain, pyrexia, or weight loss should be assessed carefully and the complications of Caroli's disease considered before attributing such symptoms to recurrent cholangitis.

Abstract: The effects of electrical stimulation of the vagi on gas transport mediated by high-frequency, low tidal volume ventilation (HFV) was examined in 10 anesthetized, paralyzed, propranolol-treated dogs. Gas transport efficiency was estimated by measuring the rate of CO2 removed from the lungs (Vco2) achieved during 45-s bursts of HFV applied before (control 1), during, and after (control 2) electrical stimulation of the transected vagi. During vagal stimulation the heart rate was maintained by electrical pacing. During the 15-s phase of vagal stimulation pulmonary impedance increased from 3.6 +/- 0.7 to 6.2 +/- 2.2 cmH2O X l-1 X s, and Vco2 increased. When the electrical stimulation of the vagi was stopped, impedance and Vco2 returned to prestimulation values. Vco2 was always higher during electrical stimulation of the vagi when HFV of a fixed volume was applied over a range of frequencies or when a fixed oscillation frequency was used over a range of tidal volumes. The effects of vagal stimulation on HFV-mediated gas transport were quite similar to the effects of moving the locations of the bias flow inlet and outlet into the lung such that tracheal volume was decreased by 20 ml, an amount equivalent to estimated change in control airway volume thought to occur during vagal stimulation. We simulated the effects of vagal stimulation and decreased tracheal volume on Vco2 by using a previously described model of HFV-mediated gas transport.(ABSTRACT TRUNCATED AT 250 WORDS)
