Technological advances during recent years and developments in anaesthesiology and intensive care have increased the interest in capnometry (measuring the CO2 content in the respiratory air). The physiological background and the principles of the method are presented. The applicability in clinical work and the limits of the method are presented and discussed.

A man aged 33 years developed an arterio-venous fistula following a gunshot wound from behind in the right calf. The quality of the fistula could be demonstrated employing digital subtraction angiographic technique while the quantity was demonstrated employing 99Tc macroaggregated albumin. The localization of the fistula is important in view of the surgical procedure and the haemodynamic amount is important to determine cardiac involvement.

The 892 human bites reported to the New York City Department of Health in 1977 were analyzed by time, place, and the victim's characteristics. The bites appeared to have a seasonality, increasing in March and exceeding the mean monthly average through August. The bite rate for the entire city, 10.7 per 100,000 population, was exceeded in 5 of the 10 Brooklyn health districts; one of these districts reported a rate of 60.9 human bites per 100,000 population. Most of the bites with identifiable locations occurred indoors (63.2 percent). In 72.8 percent of the bite episodes in which the activities surrounding them were known, these activities were aggressive in nature. Males exceeded females as bite victims in all age groups except those 10-20 and 55-60 years. Bites of the upper extremity accounted for 61.2 percent of the total bites. Left-sided bites exceeded right-sided, except for the hand. In frequency of reported occurrence, the human bite ranks third, after the dog bite and the cat bite. Human bites may be a useful indicator of antisocial behavior.
A detailed analysis of all the reported dog bites that occurred over a 2-year period in St. Louis, Mo., provided new insight not only into the severity of the problem, but also the environmental context for injury. Dog bite is a major medical problem that affects at least 1 of every 222 people and specifically 1 of every 83 children, 5 to 9 years old. Nearly 20 percent of all the children bitten were injured on the head or face, a source of concren and expense for all concerned. Nearly 10 percent of all bites were classified as serious. In only 25 percent of all injuries did the victim's behabior involve the dog at the time ofe victim interacting with the dog's owner. The victim was on the dog owner's property in about u9 percent of the incidents, and in about 48 percent of the cases the bite took pla-e near the owner's property. Bite incidents go up whenever the weather is conductive to street activity. More than 85 percent of all the biting dogs had owners. These results indicate that society's views of dog bite injury, which tend to minimize the problem and find fault with the victim, must be re-evaluated. It is time to place less emphasis on the victim and even the animal and review thae public health implications of dog ownership
