RESUMEN
SETTING: Several studies have indicated considerable variability in the biological results of different tuberculin preparations in different geographical areas or even within a single region. OBJECTIVE: To compare the biological potency of two different tuberculins. DESIGN: We performed simultaneous testing with RT23 and Merieux tuberculin in a group of 546 Police Academy students in Athens to compare reactions to both tuberculins. The students were divided into three groups according to their year of training; the participants in each group were tested using the Mantoux method simultaneously with the two tuberculins in different concentrations. RESULTS: Using a 10 mm cut-off point for a positive tuberculin skin test, positive reactions to RT23 and Merieux were highly correlated. No statistically significant difference was established. The results indicated significant superiority of the size of the reaction with RT23 tuberculin (P = 0.014). CONCLUSIONS: Both tuberculins appear to have equivalent potency, with RT23 more frequently producing reactions of larger sizes.

A fatal case of diphtheria occurred in a nonimmunized child. The child died because of the late diagnosis of the disease, which is now extremely rare.

We present a case-control study of limb reduction defects taken from autopsy material of the Pathology Department of the University of Athens from the year 1986 to 1990. During this period 1725 perinatal autopsies were performed, in which 34 neonates were found to have had a limb reduction defect (LRD) (1.97%). The cases were divided into five subgroups: transverse, intercalary longitudinal, split, and multiple types of LRD. Of all the cases, 44.17% involved the upper limb, 41.17% the lower limb, and 14.70% both. Coexisting nonlimb malformations were found in 17 cases (50%), 5 with recognized syndromes and 12 with other associated defects. Risk factors correlated with LRD were found to be low birth weight (2500 g or less) and threatened abortion.
