Prognostic significance of ST-segment depression on continuous electrocardiography in patients with acute ischemic neurologic events.
Patients with a history of ischemic stroke or transient ischemic attack (TIA) are at significant risk of cardiac death. This study reports the prognostic significance of ST-segment depression and ventricular tachycardia on continuous electrocardiography in 48 consecutive patients hospitalized with an acute ischemic stroke or TIA. Thirty-one percent of patients had episodes of asymptomatic ST-segment depression and 6% had transient ventricular tachycardia on continuous electrocardiographic monitoring. ⋯ However, ventricular tachycardia was associated with a higher rate of cardiac death (33% vs. 2%, p < 0.01). Only 27% of patients subsequently found to have coronary artery disease had ST-segment depression by continuous electrocardiography. In contrast to patients with coronary artery disease, ST-segment depression on continuous electrocardiography is not associated with poorer outcome among patients with acute ischemic stroke or TIA.

The adequate use of opioids in the treatment of chronic cancer pain requires sound knowledge of selection criteria for the various opioids, the routes of administration, dosages, dosing schemes and possible side effects. Drug selection depends on the intensity of pain rather than on the specific pathophysiology. Mild to moderate pain can often be treated effectively by so-called "weak" opioids. ⋯ True dependence or psychological addiction rarely occurs in patients with chronic cancer pain. In most cases, progression of the underlying disease associated with increasing tissue damage and increasing pain is found. Fear of dependence and addiction often contributes to undertreatment of patients suffering from chronic cancer pain.

Direct Comparison of Aspirin Plus Hirudin, Aspirin Plus Heparin, and Aspirin Alone Among 12,000 Patients with Acute Myocardial Infarction Not Receiving Thrombolysis: Rationale and Design of the First American Study of Infarct Survival (ASIS-1).
While antithrombotic therapy of acute myocardial infarction is clearly beneficial, substantial controversy exists regarding the optimal regimen. In particular, while aspirin alone has proven highly effective in reducing rates of reinfarction, stroke, and death following acute coronary occlusion, heparin has not clearly been shown to have additional benefit when added to aspirin but is associated with increased rates of hemorrhagic stroke and major bleeding. At the same time, available data for newer specific thrombin inhibitors such as hirudin suggest greater benefits than aspirin alone or aspirin plus heparin in terms of maintaining coronary flow, but possibly higher risks of hemorrhagic stroke and major bleeding. ⋯ S. subjects presenting with acute myocardial infarction and are a group at substantial risk of death, reinfarction, and stroke. Thus, the ASIS-I trial will provide importantly relevant data regarding the optimal antithrombotic regimen for the majority of patients presenting with acute myocardial infarction. In this manuscript we provide the rationale and design for the First American Study of Infarct Survival (ASIS-1), a randomized, double-blind, placebo-controlled trial directly comparing aspirin alone, aspirin plus intravenous heparin, and aspirin plus intravenous hirudin in the treatment of acute myocardial infarction patients not receiving thrombolytic therapy.

Reversible functional joint disorders (joint blockages, somatic dysfunction) of the intervertebral and rib joints can be treated using manual therapy, which improves the related segmental changes in both the dorsal and the ventral area [pseudoradicular syndrome, hyperalgesia zone (HAZ)]. This phenomenon is triggered by a decrease in the heightened nociceptor irritation in the joint capsule and in the surrounding tissues. ⋯ From our results we conclude that blocking of the peripheral nociceptors, rather than of the peripheral nerve bundles, is of primary significance for the effective treatment of anterior thoracalgia.
