| birth rate | The birth rate is usually given as the number of live births divided by the average population (or the population at midyear). This is termed the crude birth rate. In 1995, for example, the crude birth rate per 1,000 population was 14 in the United States, 16.9 in Australia, etc. (12 Dec 1998) |

| abbreviated injury scale | Classification system for assessing impact injury severity developed and published by the american association for automotive medicine. It is the system of choice for coding single injuries and is the foundation for methods assessing multiple injuries or for assessing cumulative effects of more than one injury. These include maximum ais (mais), injury severity score (iss), and probability of death score (pods). (12 Dec 1998) |
| axillary nerve injury | <neurology> A condition involving dysfunction of the axillary nerve which normally supplies the deltoid and teres minor muscles and sensation to the lateral aspect of the shoulder. This condition is a type of peripheral neuropathy that may manifest as the result of a variety of disease processes or injuries. Conditions associated with axillary nerve dysfunction include mononeuritis multiplex, fracture of the humerus, abduction injury to the shoulder, pressure to the armpit from a cast, splint or crutches. Symptoms include numbness over the outer portion of the shoulder, shoulder weakness and difficulty lifting arm or objects over your head. An EMG, nerve conduction study or muscle biopsy can be helpful in making the diagnosis. Recovery is generally spontaneous if the underlying cause can be corrected and shoulder mobility is preserved. Corticosteroid injections may be indicated in some instances. (02 Jan 1998) |
