Question: 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.

Question: Abstract: The continued influx of immigrants from Mexico, Central America, and Southeast Asia to the United States has resulted in an increased incidence of several diseases not generally seen in industrialized nations in the twentieth century. One of these is amebic abscess of the liver. This review of the diagnostic features of 57 patients with amebic abscess of the liver treated in one Los Angeles County hospital emphasizes the diagnosis and the versatility of the various roentgenologic approaches and serologic tests.

Question: Abstract: Patients with exocrine pancreatic insufficiency may absorb greater than 50% of dietary fat despite the absence of measurable pancreatic lipase activity. Nonpancreatic lipolytic activity was measured in gastric and duodenal aspirates from 5 patients with exocrine pancreatic insufficiency secondary to alcoholism and in aspirates from 5 alcoholics without evidence of exocrine pancreatic dysfunction (controls). Samples were collected under fasting and postprandial conditions. All patients with exocrine pancreatic insufficiency had nonpancreatic lipolytic activity in gastric and duodenal aspirates. Lipolytic activity in gastric aspirates was not significantly different between the patients with exocrine pancreatic insufficiency and the controls during the fasting and postprandial periods. Pancreatic insufficiency was associated with significantly (p less than 0.05) higher nonpancreatic lipolytic activity in the duodenum under fasting conditions. No significant difference between the groups was found in postprandial nonpancreatic lipolytic activity. Nonpancreatic lipolytic activity accounted for approximately 90% of total lipolytic activity at the ligament of Treitz in patients with exocrine pancreatic insufficiency as opposed to 7% in the control subjects. These observations suggest a significant role for nonpancreatic lipolytic activity (lingual lipase and gastric lipase) in fat digestion in patients with pancreatic insufficiency secondary to chronic alcohol abuse.
