Development of a multidisciplinary primary care program at the Drew University of Medicine and Science.

This article describes a required primary care curriculum for all third and fourth year medical students at the Drew/UCLA Medical Education Program. The curriculum is a supplement to the traditional medical school clinical requirements. Key features of the primary care core curriculum in the third year include a weekly half-day multidepartmental continuity clinic in a community health center serving underrepresented minority populations, a weekly didactic conference on primary care and society, a weekly clinical workshop on primary care skills, a weekly case review conference, and an orientation to primary care research methods. Fourth year medical students select a primary care subinternship that extends half days for 10 weeks in a community-based ambulatory care clinic. Fourth-year students also are required to select a mentor and conduct a research project on a primary care topic. Continuity of care records suggest that this program has been successful in allowing medical students to assume primary responsibility for a set of patients and to maintain significant levels of continuity of care over the course of the year. The evolution of the program, problems encountered, and anticipated changes in the curriculum are discussed.

Isometric detrusor pressure during bladder filling and its dependency on bladder volume and interruption to flow in control subjects.

We characterized the isometric pressures generated by the bladder during voluntary detrusor contraction and interruption of flow. Urodynamic studies were done in 34 healthy female volunteers, with a mean age of 29.6 plus or minus 9.3 years. Control urodynamics were done first to characterize bladder and urethral parameters to filling and voiding. Subsequently, isometric detrusor pressures were elicited during bladder filling at increments of 100 ml. by asking subjects to attempt to void against a urethral obstruction produced by an inflated Foley balloon. Isometric pressures also were obtained by interruption of flow through the lumen of the 22F Foley catheter. The results showed that the maximum isometric pressure increase generated remained relatively constant during bladder filling at 39.6 plus or minus 13.1 cm. water. This pressure is not significantly different from voiding pressures developed with a 10F urethral catheter. On the other hand, isometric pressure increases during voiding showed that the increase in bladder pressure following interruption of flow was volume sensitive. The possibility that this volume dependency may result in errors in the interpretation of bladder contractility is discussed.
