Protocol management of dysuria, urinary frequency, and vaginal discharge.

A proctocol to be administered by nurses for the management of dysuria, frequent urination, and vaginal discharge was validated. In a randomized, controlled trial, 146 women were seen by both nurse and physician and then assigned to either the nurse-proctocol treatment plan or the physician treatment plan. The clinical data collected by the nurse showed no important differences from the physicians' data. The protocol recommended that 89 percent of the patients be sent home without seeing the physician. The physicians agreed with the protocol-recommended disposition in all but two cases. All patients with complications were appropriately referred to the physician. In follow-up, more than 95 percent of both groups reported symptomatic improvement, and repeat urine cultures were negative. We conclude that the protocol can be accurately administered, makes sound recommendations, is safe, and efficiently saves physician time.

Sympathetic nerve activity: a link to stroke?

Spontaneously hypertensive rats (SHR) have been shown to have an increased capacity for superior cervical sympathetic nerve activity which may protect against stroke (Mueller et al: Stroke 13: 115, 1982). Sympathetic nerve activity has never been examined in the stroke-prone substrain of SHR (SP). In this study we measured superior cervical sympathetic nerve activity during rest and during a maximal sympathetic response in SHR, SP, and their normotensive controls, Wistar-Kyoto (WKY). The resting superior cervical sympathetic nerve activity of SP was significantly less than SHR (p less than 0.02) but not different from WKY. During central ischemia, used to induce maximal sympathetic response, the increase in SP sympathetic nerve activity was significantly less than SHR (p less than 0.001) but was not different from WKY. This diminished capacity for elevated superior cervical sympathetic nerve activity in stroke-prone SHR may relate to their increased predisposition to stroke because sympathetic hyperactivity cannot protect cerebral vessels during acute hypertension.
