In 2007, 5,488 workers died from job injuries, 92% of which were men, and 49,000 died from work-related injuries. NIOSH estimates that 4 million workers in the U.S. in 2007 sustained non-fatal work related injuries or illnesses.According to data from the National Institute for Occupational Safety and Health (NIOSH) and the Bureau of Labor Statistics, an average of 15 workers die from traumatic injuries each day in the United States, and an additional 200 workers are hospitalized.In a study in the state of Washington, injured workers were followed for 14 years to determine the long term effects of work injury on employment. The work injuries resulted in an average of 1.06 years of lost productivity for each of the 31,588 allowed claims.In 2010, 25% of occupational injuries and illnesses that were not fatal but caused work absences were related to injuries to the upper limb. Dangerous sectors
In the U.S. the Bureau of Labor Statistics makes available extensive statistics on workplace accidents and injuries. For example:

Common injuries
As in the United Kingdom, slips, trips and falls (STF) are common and account for 20-40% of disabling occupational injuries. Often these accidents result in a back injury that can persist to a permanent disability. In the United States, a high risk of back injuries occurs in the health care industry. 25% of reported injuries in health care workers in the state of Pennsylvania are for back pain. Among nurses, the prevalence of lower back pain may be as high as 72% mostly as a result of transferring patients.
Additionally, the number of keratin-10 positive cells and HLA-DR expression was higher as compared to psoriasis. In ILVEN without associated psoriasis all T-cell subsets and cells expressing NK receptors were reduced as compared to psoriasis, except for CD45RA+ cells. In particular the density of CD8+, CD45RO+ and CD2+, CD94 and CD161 showed a marked difference between ILVEN without psoriasis and psoriasis itself. T cells relevant in the pathogenesis of psoriasis are markedly reduced in ILVEN without psoriasis as compared to psoriasis. Treatment
Reported treatments include topical agents, dermabrasion, cryotherapy, laser therapy, and surgical excision. These therapies have a high failure rate because of incomplete relief of symptoms, scarring, or recurrence. Though similar in appearance, ILVEN will not respond to therapies known to affect psoriasis. ILVEN can be very difficult to live with but can be treated. The most effective method is full-thickness excision of the lesion. CO2 Laser Surgery can resurface the skin to give a flat, smoother and more normal appearance, but does not remove the lesion. History
The condition later known as ILVEN was first described by Paul Gerson Unna in 1896. ILVEN appears very similar to psoriasis. However, it was not until 1971 that the disorder was described and clearly defined as a distinct entity by Altman and Mehregan in a case study of 25 patients. The Dupre and Christol described histopathological criteria in 1977. Epidemiology
ILVEN usually appears in infancy or early childhood. The condition is very rarely begun in adulthood. ILVEN occurs predominantly in females (female-male ratio, 4:1) with no racial predominance.
