Substance abuse units taught by four specialties in medical schools and residency programs.

Four medical specialty organizations conducted a survey of 294 departments in 98 medical schools and 1,124 residency programs to identify the number and type of curriculum units on substance abuse offered by these specialties. A curriculum unit was defined as a formal block of teaching on substance abuse. A total of 251 (85 percent) of the medical school departments and 828 (74 percent) of the residency programs responded. Of those, 175 (70 percent) of the medical school departments and 479 (58 percent) of the residency programs reported offering at least one curriculum unit on substance abuse. There was considerable variation among the four specialties in the number and percentage of departments or programs reporting such units. Overall, a majority of the units addressed both alcohol and other drugs, were required, and included a clinical component. Evaluations of content and teaching strategies are needed to examine the quality and adequacy of substance abuse training.

Effects of tissue preincubation and hypoxia on CA3 hippocampal neurons in the in vitro slice preparation.

Using the in vitro hippocampal slice preparation, we studied the electrophysiological properties of pyramidal cells in tissue that was 'preincubated' (2-6 h in a large, static volume of oxygenated bathing medium) before being placed in an interface chamber for study. Striking differences were found in 'preincubated' vs 'non-preincubated' CA3 cells. The preincubated cells had more negative resting potentials, higher input resistance, lower threshold for stimulus-evoked burst discharge and larger hyperpolarizing afterpotentials. Cells in the preincubated CA3 region were also more likely to show spontaneous synchronized burst discharge, but were relatively resistant to hypoxia-induced spreading depression. CA1 cells were less dramatically affected by preincubation, showing little difference from their non-preincubated counterparts. Possible mechanisms involved in the CA3 preincubation effect, including glial buffering alterations and changes in Na+, K+-ATPase activity, are discussed.

Creating a substance abuse network in family medicine: lessons learned.

Family practice was one of several primary care specialties awarded federal contracts in 1985 to survey substance abuse training needs. Family medicine has since excelled in creating a viable substance abuse network. Key events were the sponsorship of a fellowship program, the formation of the Society of Teachers of Family Medicine (STFM) Substance Abuse Working Group, and the working group's pursuit of externally funded projects. Tangible measures of the network's success include collective funding exceeding $7.3 million, an increase in the number of substance abuse activities at annual STFM conferences, and a nearly four-fold growth in the group's membership and collaborative publications. Key factors underlying the vitality of the network that may be generalizable include: 1) initial emphasis on training family physician faculty; 2) making optimal use of the existing administrative channels within STFM; 3) acquisition of external funding; 4) some continuity of core persons working together; 5) active networking within and outside family medicine; and 6) promotion of individual success.
