On estimating census undercount in small areas.

"Net undercount rates in the U.S. decennial census have been steadily declining over the last several censuses. Differential undercounts among race groups and geographic areas, however, appear to persist. In the following, we examine and compare several methodologies for providing small area estimates of census coverage by constructing artificial populations. Measures of performance are also introduced to assess the various small area estimates. Synthetic estimation in combination with regression modelling provide the best results over the methods considered. Sampling error effects are also simulated. The results form the basis for determining coverage evaluation survey small area estimates of the 1900 decennial census."

Epinephrine-resistant anaphylaxis in a patient taking propranolol hydrochloride.

A patient taking propranolol hydrochloride, 40 mg twice daily, had a constitutional reaction several minutes after receiving a maintenance allergy injection. When the reaction proved resistant to treatment with aqueous adrenalin, intubation with 100% oxygen ventilation and the intravenous administration of sodium bicarbonate with pancuronium bromide, diphenhydramine hydrochloride and dexamethasone was required for the patient's recovery. Physicians should be aware that, in allergy patients, low doses of propranolol hydrochloride can result in acute pulmonary failure.
