Urinary excretion of benzoylecgonine following ingestion of Health Inca Tea

Four males ingested one cup of Health Inca Tea which contained 1.87 mg of cocaine. Urine specimens collected for 36 h post-ingestion were analyzed for benzoylecgonine (BE) by EMIT-d.a.u., TDx and gas chromatography/mass spectrometry (GC/MS). Positive immunoassay results were obtained for 21-26 h post tea ingestion. Discrepant immunoassay results occurred with only one specimen: EMIT positive; TDx negative, 0.25 mg/l; GC/MS, 0.273 mg/l. Quantitative TDx results were well correlated with GC/MS results, r2 = 0.963, n = 45. Maximum urinary BE concentrations ranged from 1.4-2.8 mg/l, occurring from 4-11 h, post ingestion. Total BE excretion in 36 h ranged from 1.05 to 1.45 mg, 59-90% of the ingested cocaine dose. Urinary excretion rate constant (Km) ranged from -0.073 to 0.111/h. Health Inca Tea ingestion should be considered when interpreting urinary BE concentrations.     

Frequency of pulmonary hemosiderosis in Eastern North Carolina

Pulmonary hemosiderosis has been attributed to airborne fungi in water-damaged homes in studies of a cluster of cases in infants and children in Cleveland, Ohio, in 1997. We have searched for such emerging infectious agents in the Coastal Plain of North Carolina, which is subject to intermittent flooding. Pulmonary tissue from 206 infants and young children whose deaths had been investigated from October 1978 to September 1996 was retained at East Carolina University School of Medicine. Ages ranged from premature newborns to 49-months. One hundred and ten deaths were attributed to sudden infant death syndrome (SIDS). New sections were cut and analyzed using hematoxylin and eosin, Prussian blue for iron, and Gomori methenamine silver for fungal organisms. Twenty-three infants and children had iron-containing macrophages. Sixteen of these had underlying illnesses, but 4 were originally diagnosed as SIDS. Only one of these had sufficient hemosiderosis to be considered as having pulmonary hemosiderosis and no fungi were present. One case without iron had fungi and was not originally diagnosed as SIDS. The single case of pulmonary hemosiderosis found in this rural area is not similar to the cluster in Cleveland. The study identifies no fungal organisms as emerging infectious diseases in this area.
