Crackles in the early detection of asbestosis.

We studied 386 workers exposed to asbestos to assess the value of chest auscultation by a trained technician in detecting asbestosis as defined by previously reported clinical, physiologic, and roentgenologic criteria. The presence and degree of crackles were assessed at preselected basilar lung sites by a technician whose performance was validated by comparison with computer-generated time-expanded waveforms of tape recordings of lung sounds. Asbestosis was present in only 2.8% of the total population, but it was present in 8.6% of those with over 25 yr or more of employment. The technician correctly identified all the workers in whom the diagnosis was most certain, that is, those with all criteria positive. The overall true positive rate was 55%. The majority (94.8%) of those with no abnormal criteria were correctly classified. Auscultation by an objectively validated technician can be a useful noninvasive method for screening industrial populations exposed to asbestos.

Sahel nutrition survey, 1974.

In time of food shortage, accurate assessment of nutrition status is important so that effective aid may be directed to those in greatest need and, in the future, the impact of this aid on the nutritional situation may be assessed. Using a population proportional sampling method and the index weight for height (which is relatively independent of sex, race, and age) as a criterion of nutritional status, CDC investigators determined that about 10% of the sampled population (aged about 6 months through 6 years) in Mali, Mauritania, Niger, and Upper Volta and over 20% in the sampled population in Chad were severely and acutely undernourished. Apparently younger children were affected first, but as the food shortage became more severe the prevalence of undernourished older children increased. This method of nutrition surveillance has proven itself during a stressful period and should be considered a fundamental tool when rapid assessment of acute undernutrition in children in developing nations is required.
