Transient bilateral brainstem dysfunction caused by topical administration of papaverine.

Papaverine has been associated with transient cranial nerve dysfunction after topical application during craniotomy. The authors report similar dysfunction after the use of papaverine affected brainstem structures. Two patients undergoing craniotomy for clipping of an aneurysm experienced bilateral depression of cortical somatosensory evoked potentials to both median and tibial nerve stimulation after administration of papaverine. Arterial blood gas analysis, hemodynamic parameters, and anesthetic levels remained constant throughout these somatosensory evoked potential changes. In addition, intraoperative angiography and immediate postoperative CT imaging showed intact blood flow with complete exclusion of the aneurysm. Both patients recovered within 1-2 hours and had normal neurological examination findings after extubation. Topical papaverine use may be associated with direct effects on brainstem structures. The transient nature of those changes suggests that aggressive intervention may not be needed. Maneuvers to limit the spread of papaverine to basal cisterns should be considered.

Time in continuity clinic as a predictor of continuity of care for pediatric residents.

OBJECTIVE: In 1996, the Residency Review Committee-Pediatrics recommended doubling time in continuity clinic to 2 half days per week. It has yet to be demonstrated that increased time in clinic yields greater continuity of care. The objective of this study was to determine whether increasing the number of half days spent in clinic improves continuity of care for residents. METHODS: We reviewed computerized encounter records for all Medical University of South Carolina pediatric residents from 1982 to 1998. Depending on the year and the resident's training level, house staff spent varying amounts of time in continuity clinic. Time in clinic was estimated from grants and materials generated in the residency program. We calculated continuity of care from the resident's perspective for each individual resident per year using the Continuity for Physician (PHY) formula. RESULTS: Continuity for 488 resident-years (200 residents) was evaluated. Residents spent from 10% to 30% of their time per year in clinic. Mean PHY was 57% (interns), 62% (second-year residents), and 52% (third-year residents). The correlation coefficient (R) between PHY and percentage of time in clinic was .22. In multivariable modeling, percentage of time in clinic, training level, and year predicted continuity. An increase of 1 half day in clinic was associated with an 11% increase in physician continuity. When analyses were limited to sick visits, R improved to .58. The effect size remained 11%. However, training level and academic year were no longer significant. CONCLUSION: Increasing time spent in clinic improves continuity and may indeed enhance the quality of this fundamental experience.

Preventive services: blood pressure checks at well child visits.

The objective of this study was to determine rates of blood pressure (BP) screening at well-child visits as recommended by the Task Force on Blood Pressure Control in Children. The 1985 and 1996 National Ambulatory Medical Care Surveys were analyzed for changes in proportion of well visits for children aged 3-18 years at which BP was checked. Patient and physician demographics are described. BP screening increased from 50% in 1985 to 61% in 1996. For pediatricians, the estimates were 50% (95% CI, 43-57) and 60% (95% CI, 53-68). For family/general medicine the estimates were 51% (95% CI, 34-69) and 58% (95% CI, 43-74). Age, geographic location, and length of a visit were significant in predicting BP screening. Gender, race, ethnicity, or urban location were not. A stepwise logistic regression confirmed these results. Rates of screening BP at well-child visits have increased but fall short of current recommendations. High-risk children are not screened at a rate different from their lower risk peers.
