Second varicella infections: are they more common than previously thought?
Clinical varicella reinfections may occur more commonly than previously thought. Additional studies of the predictive value of a positive varicella history and laboratory studies of reported reinfections are indicated to guide varicella vaccination policy.
Contrary to common perceptions, FMDs are not uncommon in the elderly, and 1 in 5 patients in the current cohort, onset of FMD occurred after age 60 years. Gait abnormalities and psychogenic nonepileptic seizures may be more common in older patients.
