Effectiveness of Residential Acaricides to Prevent Lyme and Other Tick-borne Diseases in Humans.

Background: In the northeastern United States, tick-borne diseases are a major public health concern. In controlled studies, a single springtime application of acaricide has been shown to kill 68%-100% of ticks. Although public health authorities recommend use of acaricides to control tick populations in yards, the effectiveness of these pesticides to prevent tick bites or human tick-borne diseases is unknown.

Rates of knee injury in the U.S. Active Duty Army, 2000-2005.

We sought to summarize knee injuries (KI) in the U.S. Active Duty Army (ADA) in terms of absolute numbers, examine current rate trends, and identify ADA who were at increased risk for experiencing a KI.

Rhabdomyolysis in the US Active Duty Army, 2004-2006.

Purpose: Rhabdomyolysis (RM) is a skeletal muscle disorder resulting in severe cellular injury caused by vigorous physical activity and other systemic etiologies. RM is associated with significant morbidity, such as acute renal failure, and can be fatal. RM that occurs in the US Active Duty Army (ADA) results in time lost from training, deployment, and combat.

Rates of ankle and foot injuries in active-duty U.S. Army soldiers, 2000-2006.

Ankle and foot injuries (AFI) are a major cause of Active-Duty Army (ADA) soldiers' time lost from training and combat operations. We used the Total Army Injury and Health Outcomes Database to compute the rates of AFI to identify high-risk ADA groups for the years 2000-2006. During this time, 16% of soldiers were clinically seen at least once for an AFI.

Deployment to a combat zone and other risk factors for mental health-related disability discharge from the U.S. Army: 1994-2007.

Combat exposure is associated with subsequent mental health symptoms, but progression to mental health disability is unclear. Army soldiers discharged with mental health disability (n = 4,457) were compared to two matched control groups: other disability discharge (n = 8,974) and routine discharge (n = 9,128). In multivariate logistic models, odds of mental health disability discharge versus other disability and routine discharge were significantly higher for soldiers deployed to combat zones; odds ratios increased with deployment time.

Is lipstick associated with the development of systemic lupus erythematosus (SLE)?

Lipstick use has been hypothesized to be a risk factor of developing systemic lupus erythematosus (SLE). The objective of this study was to investigate the association between lipstick use and risk of SLE. We performed an Internet-based case-control study of SLE with Google users searching on medical key terms as the source population.

Feasibility and validity were demonstrated of an online case-control study using the prototype of recent-onset systemic lupus erythematosus.

Objective: To test the feasibility and validity of the online case-control study design through the empirical deployment of a prototype study of recent-onset systemic lupus erythematosus (SLE).

Study Design And Setting: We conducted an Internet-based case-control study of SLE during 2003-2005. The source population comprised Google users searching on medical key terms, solicited using sponsored links.
