Comparison of the conventional lecture method and the self-instruction method for teaching clinical pathology.
Two separate courses in clinical pathology were presented to two groups of second-year medical students. The first (large) group was taught by the conventional lecture method; the other (small) group, by a self-instructional method for roughly half of the course, followed by the conventional lecture method for the second half of the course. The effectivenesses of the two methods were compared, based on performances on the final written examination. It was found that the self-instructional method was as effective as the conventional method in teaching clinical pathology, at least in teaching basic principles and interpretive clinical chemistry, as judged by the performances of the two groups. Surprisingly, the two groups differed significantly in performances on the portion of the course taught by similar methods.

A technic for bone marrow imprints from postmortem specimens.
A simple technic for making bone marrow imprints from postmortem specimens is described. The preparations are highly reproducible, retaining excellent cytologic detail with minimal cell distortion and can be used for evaluation of cellularity.

Anti-M in children with acute bacterial infections.
Four children, 7 to 24 months old, were found to have anti-M at the time of admission to the hospital for severe acute bacterial infections. All were M-N+. Two patients had meningitis, one had septic arthritis, and the fourth had a third-degree burn of the left hand. In follow-up studies the anti-M of patients No3 and No4 were no longer detectable after 12 and 11 months respectively. In all patients no demonstrable antibody was in either maternal or cord sera at time of birth. The clinical data and bacterial isolations lead us to postulate that bacterial infections account for the formation of naturally occurring anti-M in M-negative persons.
