It was concluded that ciprofloxacin in both regimens of as much as 2 g daily is as effective as d0xycycline for the treatment of t h e c l i n i c a l s y n d r o m e of n o n gonococca] urethritis, but that the ciprofloxacin regimens were ineffective in curing chlamydial urethritis.

Delayed onset of intestinal obstruction in children a f t e r unrecognized seat belt injury Hardacre JM, West KW, Rescorla FR, et al J Pediatr Surg 25:967-969 Sep 1990
Safety seats and seat belts have considerably decreased the mortality of children involved in motor Vehicle accidents. However, the use of these devices has contributed to the increasing number of cases of a spectrum of injuries, including intestinal perforation, mesenteric disruptions, lumbar fractures, and dislocations, termed the "seat belt syndrome." The authors present two cases of delayed-onset intestinal obstruction attributed to Unrecognized abdominal trauma. In both cases, the children were restrained with adult lap belts only. Both had significant concomitant injuries (L-4 vertebral compres sion fracture and splenic rupture, respectively) and presented three to six weeks after the accident with symptoms of small bowel obstruction: bilious emesis, nausea, and abdominal pain. The children were evaluated by abdominal radiograph in one case and abdominal computed tom0graphy and a small bowel contrast study in the other. At exploratory laparotomy, both were found to have volvulus secondary to an omental adhesion, Most visceral injuries are detected and treated promptly, often with the aid of the seat belt sign: 20:1 January 1991
contusions, petechiae, and abrasions across the chest or lower abdomen. Recommendations are to maintain a high index of suspicion for these injuries, encourage the use of shoulder harnesses, and promptly investigate the signs and symptoms of smallbowel obstructions in the post-traumatic pediatric patient.

motor vehicle accidents, smoking
Risk of automobile a c c i d e n t s in c i g a r e t t e smokers Brison RJ Can ,J Pubfic Health 81:102-106 Mar 1990
Cigarette smoking has been shown to be a risk factor for accidental injury. Controversy remains whether smokers have an increased risk of motor vehicle crash that is independent of alcohol use. The author undertook a case-control study to identify any increased risk of motor vehicle crash m cigarette smokers over nonsmokers. To minimize variability expected by age and sex with respect to known risk factors of motor vehicle crashes Lalcohol use, number of miles driven per year, car ownership), the sample was restricted to men from 30 to 39 years old. Cases were defined as presence of a motor vehicle crash over a two-year period, and crashes studied were those resulting in property damage alone. Twentyone hundred self-administered questionnaires Ii,100 control and 1,000 case) were mailed to Washington state residents asking about motor vehicle crash history, smoking status, proportion of time one smokes while driving, usual use of alcohol, usual driving speed, average annual mileage, age, income, and marital status; the response rate was 55%. Questionnaires lacking information on s m o k i n g or other i n f o r m a t i o n were excluded, resulting in a sample of 595 cases and 548 controls. The case group included those individuals w i t h d o c u m e n t e d m o t o r vehicle crash on state motor vehicle records and/or those declaring themselves inAnnals

volved in a motor vehicle crash on the questionnaire. The Case group was then subdivided into those admitting to at least partial responsibility for the accident (356) and those not at fault (239). Unadjusted relative risk estimates and logistic regression analysis found that for drivers at fault, cigarette smokers have a 50% higher risk for motor vehicle crash. Increased number of miles driven per year and younger age increased risk regardless of fault. Alcohol was not a statistically significant risk factor for motor vehicle crash in this group, although a trend toward increasing risk of crash with increasing alcohol use was noted. Increased risk for motor vehicle crash also was seen with increasing frequency of smoking while driving. Seat belt use, speed while driving, income. and marital status were not found to be statistically significant risk factors for motor vehicle crashes. It was concluded that there is an association between smoking and automobile accidents that is likely to be independent of the risk of alcohol use, and the t e n d e n c y to s m e k e while driving shows a strong association with the risk of motor vehicle crashes. Several postulates as to why a relationship between motor vehicle crash and smoking may exist include distraction from driving, behavioral differences in smokers, and possible carbon monoxide toxicity.
