Randomized Controlled Trial Comparative Study Clinical Trial
Intermittent injection vs patient-controlled analgesia for sickle cell crisis pain. Comparison in patients in the emergency department.
--The purpose of this study is a prospective assessment of morphine sulfate administration by intermittent intravenous (IV) injections (Int-IV) vs patient-controlled analgesia (PCA) in patients in the emergency department (ED) with sickle cell crisis pain. ⋯ --At both the low- and high-dose regimens, PCA is equally safe and effective and may be used in place of Int-IV administration of morphine in the ED treatment of sickle cell crisis pain.

Sarcoidosis is a multisystem disorder of unknown cause. The disease is characterized by the presence of noncaseating granulomas in the affected tissue system. ⋯ The disease appears in the differential diagnosis of many infectious and noninfectious neurological syndromes. We have reviewed all aspects of neurosarcoidosis from the point of view of practicing internists, including the clinical manifestations, cerebrospinal fluid and radiographic changes, differential diagnosis, and treatment.

Prospectively collected data on the incidence of treated hypertensive end-stage renal disease (HT-ESRD) were analyzed to investigate whether the higher rate of HT-ESRD in blacks compared with whites is due to differences in putative ESRD risk factors. The overall age-adjusted relative risks of HT-ESRD for black compared with white residents in the Maryland Regional ESRD Registry (Network 31) Catchment Area were 7.4 (95% confidence interval, 5.9 to 9.4) and 9.9 (95% confidence interval, 7.4 to 13.1) for men and women, respectively. In a population level analysis, race-specific HT-ESRD incidence rates in the black and white populations of 13 regions in Network 31 were related to the prevalence of putative ESRD risk factors in those populations. ⋯ The HT-ESRD incidence in a population was also directly related to that population's prevalence of hypertension, severe hypertension, and diabetes mellitus and inversely related to measures of socioeconomic status and mean age at diagnosis of hypertension. When adjusted simultaneously for age, prevalence of hypertension, severe hypertension, diabetes, and level of education, the risk of HT-ESRD was still 4.5 (95% confidence interval, 3.2 to 6.2) times higher for black compared with white populations. Our findings failed to support the hypothesis that race-related differences in the prevalence, severity, or age at onset of hypertension, in the prevalence of diabetes or in socioeconomic status, explain the well-recognized black-white differences in the HT-ESRD incidence.

Three patients with untreated sleep apnea fell asleep while driving and caused serious automobile accidents. One person died, another became permanently paraplegic, and the three patients with sleep apnea were seriously injured in these crashes. This sequela of sleep apnea is not surprising, since subjects with sleep apnea may be poor drivers with a high accident rate and a high incidence of "near-miss" vehicular incidents. ⋯ Second, physicians must consider the diagnosis of sleep apnea when examining patients who fall asleep while driving. Next, physicians must warn their patients with sleep apnea about the risks of driving with untreated sleep apnea. Finally, physicians must treat any seriously impaired driver with sleep apnea and keep these patients from driving until they can receive successful treatment.
