The purpose of this study was to determine whether patients and their families found ethics consultations to be helpful and whether they were satisfied with the treatment decisions that were made in those cases where ethics consultation was requested. ⋯ Patients and families found ethics consultation provided by clinical ethicists at Loma Linda University Medical Center to be helpful in a majority of instances, and rarely found them detrimental. Based on an analysis of their comments, we believe ethics consultations were perceived as helpful in 7 ways: increased clinical clarity, increased moral or legal clarity, motivation to do what they believe is right, facilitation of the process of decision-making, implementation of a decision, interpretation of technical language, and consolation and support.

Chronic pain differs from acute pain in that it serves no useful function, causes suffering, limits activities of daily living, and increases costs of healthcare payments, disability, and litigation fees. Pain perception begins with activation of peripheral nociceptors and conduction through myelinated A delta and unmyelinated C fibers to the dorsal root ganglion. From here, signals travel via the spinothalamic tract to the thalamus and the somatosensory cortex. ⋯ Descending pathways from the hypothalamus, which has opioid-sensitive receptors and is stimulated by arousal and emotional stress, can transmit signals to the dorsal horn that modulate ascending nociceptive transmissions. Modulation to alter the perception of pain also can occur at higher centers (e.g., frontal cortex, midbrain, medulla) by opioids, anti-inflammatory agents, as well as antagonists and agonists of neurotransmitters. This article will review our current knowledge of the mechanisms involved in (1) the transduction of tissue injury or disease signals (nociception and nociceptive receptors); (2) the transmission of signals rostrally to the thalamus and higher nervous system centers (involving perception of the quality, location, and intensity of noxious signals); and (3) the modulation of ascending sensory messages at all levels (periphery, spinal cord, and higher centers).

Management of type II diabetes is difficult, particularly in urban populations with limited resources and access to care. To evaluate the effectiveness of structured care delivered by non-physician providers, patients were studied prospectively for 6 months in a municipal hospital diabetes clinic. ⋯ In urban African American patients, nonpharmacologic management of type II diabetes substantially improves metabolic control; decreases in HbA1c are comparable in those who do and do not lose weight. Therapy managed by nonphysician providers can be an effective cornerstone of diabetes care in this socioeconomically disadvantaged population.

Randomized Controlled Trial Comparative Study Clinical Trial
Oral antibiotic treatment of right-sided staphylococcal endocarditis in injection drug users: prospective randomized comparison with parenteral therapy.
To compare the efficacy and safety of inpatient oral antibiotic treatment (oral) versus standard parenteral antibiotic treatment (intravenous) for right-sided staphylococcal endocarditis in injection drug users. ⋯ For selected patients with right-sided staphylococcal endocarditis, oral ciprofloxacin plus rifampin is effective and is associated with less drug toxicity than is intravenous therapy.

To assess the accuracies of four commonly used parameters in predicting weaning outcome and whether breathing pattern changes during weaning. ⋯ The RVR is more accurate than other commonly utilized clinical tools in predicting the outcome of weaning from mechanical ventilation. The RVR measured at 30 minutes is superior to the RVR in the first minute of weaning. The predictive accuracy and unique simplicity of the RVR justify its use in the care of mechanically ventilated patients.
