An 8-ft-high fence may be added to keep deer away from the tick-safe zone. Occupational exposure
Outdoor workers are at risk of Lyme disease if they work at sites with infected ticks. This includes construction, landscaping, forestry, brush clearing, land surveying, farming, railroad work, oil field work, utility line work, park or wildlife management. U.S. workers in the northeastern and north-central states are at highest risk of exposure to infected ticks. Ticks may also transmit other tick-borne diseases to workers in these and other regions of the country. Worksites with woods, bushes, high grass or leaf litter are likely to have more ticks. Outdoor workers should be most careful to protect themselves in the late spring and summer when young ticks are most active. Host animals
Ticks can feed upon the blood of a wide array of possible host species, including lizards, birds, mice, cats, dogs, deer, cattle and humans. The extent to which a tick can feed, reproduce, and spread will depend on the type and availability of its hosts. Whether it will spread disease is also affected by its available hosts. Some species, such as lizards, are referred to as "dilution hosts" because they dont tend to support Lyme disease pathogens and so decrease the likelihood that the disease will be passed on by ticks feeding on them. White-tailed deer are both a food source and a "reproductive host", where ticks tend to mate. The white-footed mouse  is a reservoir host in which the pathogen for Lyme disease can survive.
Injury of axillary nerve (axillary neuropathy) is a condition that can be associated with a surgical neck of the humerus fracture. It can also be associated with a dislocated shoulder or with traction injury to the nerve, which may be caused by over-aggressive stretching or blunt trauma that does not result in fracture or dislocation. One form of this injury is referred to as axillary nerve palsy. Injury most commonly occurs proximal to the quadrangular space.Injury in this nerve causes paralysis (as always) to the muscles innervated by it, most importantly deltoid muscle. This muscle is the main abductor of the shoulder joint from 18 to 90 degrees (from 0 to 18 by supraspinatus). Injury can result in a reduction in shoulder abduction. So a test can be applied to a patient with injury of axillary nerve by trying to abduct the injured shoulder against resistance.The pain from axillary neuropathy is usually dull and aching rather than sharp, and increases with increasing range of motion. Many people notice only mild pain but considerable weakness when they try to use the affected shoulder. References
