A Longitudinal Study of Medicaid Coverage for Tobacco Dependence Treatments in Massachusetts and Associated Decreases in Hospitalizations for Cardiovascular Disease

Thomas Land and colleagues show that among Massachusetts Medicaid subscribers, use of a comprehensive tobacco cessation pharmacotherapy benefit was followed by a substantial decrease in claims for hospitalizations for acute myocardial infarction and acute coronary heart disease

Revisions to the derivation of the Australian and New Zealand guidelines for toxicants in fresh and marine waters

The Australian and New Zealand Guidelines for Fresh and Marine Water Quality are a key document in the Australian National Water Quality Management Strategy. These guidelines released in 2000 are currently being reviewed and updated. The revision is being co-ordinated by the Australian Department of Sustainability, Environment, Water, Population and Communities, while technical matters are dealt with by a series of Working Groups. The revision will be evolutionary in nature reflecting the latest scientific developments and a range of stakeholder desires. Key changes will be: increasing the types and sources of data that can be used; working collaboratively with industry to permit the use of commercial-in-confidence data; increasing the minimum data requirements; including a measure of the uncertainty of the trigger value; improving the software used to calculate trigger values; increasing the rigour of site-specific trigger values; improving the method for assessing the reliability of the trigger values; and providing guidance of measures of toxicity and toxicological endpoints that may, in the near future, be appropriate for trigger value derivation. These changes will markedly improve the number and quality of the trigger values that can be derived and will increase end-users’ ability to understand and implement the guidelines in a scientifically rigorous manner

Response of babesiosis to pentamidine therapy

Three nonsplenectomized patients were infected with Babesia microti. One had fever, abdominal pain suggesting gallbladder disease, and evidence of disseminated intravascular coagulation; another was considered to have lymphoma, partly because two smears for Babesia before admission were negative. All three patients were treated with pentamidine isethionate and improved clinically. Parasites were no longer seen on smears after 5 days of therapy, but Babesia could still be recovered by hamster inoculation 5 weeks after therapy in one of the patients tested, underscoring the need for this test to properly evaluate eradication of the organism. In one patient, pentamidine was stopped after 7 days because of increased creatinine concentration, and this amount of drug appeared adequate to control the parasitemia. Pain at drug injection sites was a major side effect in all three patients. Pentamidine appears to be useful in controlling clinical manifestations of babesiosis and decreasing parasitemia, but it does not eradicate the organism
