Abstract Among 174 children with blistering distal dactylitis or paronychia, 36.2% had a positive group A Streptococcus (GAS) rapid detection antigen. For GAS, the outcome for patients who received amoxicillin was favorable in all cases without any surgical procedures; 44.6% of cases due to Staphylococcus aureus infection (38.7%) required surgery.

Redd and co-workers found the sensitivity of their rapid diagnostic test for group A streptococcal pharyngitis to be 62.8% and its specificity to be 96.9%. Furthermore, the positive predictive value of the test was determined to be 91.5%, sufficiently high to significantly influence the care provided to their patients. We strongly disagree with the authors' conclusion that their findings can be extrapolated to the general pediatric setting. Bayes theorem clearly relates a test's positive predictive value to its sensitivity as well as to the prevalence of true disease in the population.

ABSTRACT We describe the development and evaluation of a rapid diagnostic test for Vibrio cholerae O1 and O139 based on lipopolysaccharide detection using gold particles. The specificity ranged between 84 and 100%. The sensitivity of the dipsticks ranged from 94.2 to 100% when evaluated with stool samples obtained in Madagascar and Bangladesh. The dipstick can provide a simple tool for epidemiological surveys.
