BACKGROUND Certain infections can trigger chronic fatigue syndromes (CFS) in a minority of people infected, but the reason is unknown.

We assessed whether attention in normal-weight, sated participants was drawn to food items specifically when that(More)

Test-retest reliability and internal consistency of the Terry, a cartoon-based child mental health screener developed for African-American children, were measured in 36 boys (age 5 1/2 to 13) in a test-retest design. Reliability of the diagnosis (0.70 < or = k < or = 0.75) was good for ADHD, ODD, CD, and OAD, and excellent for MDD and SAD. Because of low(More)

There is a need to develop public health approaches to motivate people to reduce their intake of junk food. OBJECTIVE To assess the effect of health and social norm messages on high calorie snack food intake (a(More)

METHOD A prospective cohort study of 250 primary care patients, presenting with glandular fever or an ordinary upper respiratory tract infection (URTI). RESULTS The incidence of an acute fatigue syndrome was 47% at onset, after(More)
