(a) To determine if self-reported diabetes mellitus is independently associated with sleep-disordered breathing (SDB); (b) to determine if diabetes mellitus is specifically associated with central sleep apnea including periodic breathing (Cheyne-Stokes breathing pattern) during sleep. ⋯ The authors concluded that diabetes mellitus is associated with sleep apnea but that this association is largely explained by risk factors in common for both disorders, most notably obesity. After adjusting for confounding factors there was no difference between diabetic and non-diabetic participants with regard to obstructive events. However, even after adjusting for potential confounders, there was a greater prevalence of periodic breathing in diabetic subjects. Although not reaching statistical significance, there was a suggestion of an increased prevalence of central events in the diabetic population, particularly when the sample included participants with known CVD. The investigators believed it unlikely that the findings were attributable to underlying congestive heart failure in as much as the diabetic subjects without prevalent CVD exhibited increased prevalence of periodic breathing and possibly increased central events. The authors proposed that diabetes mellitus might be a cause of SDB, mediated through autonomic neuropathy that may alter ventilatory control mechanisms. In this context, the authors commented that autonomic neuropathy may cause perturbations in ventilatory control by altering chemoreceptor gain or altering cardiovascular function (although the authors discounted underlying congestive heart failure as an explanation for the higher prevalence of periodic breathing in diabetic participants). To reinforce their conclusions, the authors cited the literature indicating increased prevalence of sleep apnea in diabetic patients with autonomic dysfunction, as well as the association between Shy--Drager syndrome, in which autonomic insufficiency is a constitutive element, and central sleep apnea.

Repair of adult Scimitar syndrome with an intra-atrial conduit.
The management of Scimitar syndrome in adulthood is controversial, with no guidelines for surgical correction. We present the case of a 66-year-old woman who presented late in life with Scimitar syndrome and a significant left-to-right shunt. We describe repair using an intra-atrial conduit from the anomalous vein to the foramen ovale, with a successful outcome.

This study sought to determine the efficacy of fluoroscopic caudal epidural steroid injections as a conservative treatment in patients with presumably chronic lumbar discogenic pain. ⋯ At greater than two year follow-up, the efficacy of fluoroscopically guided caudal epidural steroid injections in patients with chronic lumbar discogenic pain is poor. Patient satisfaction exceeds the reported rate of efficacy. Patients responding to injection have significantly lower pre-injection pain scores.

There is growing evidence that in end-stage shock or during cardiac arrest, inappropriately low endogenous vasopressin plasma levels may be responsible for pathologic vasodilatation, inadequate organ perfusion, and poor outcome. The purpose of this article is to review recent publications featuring arginine vasopressin as a potent vasoconstrictor in various shock states such as systemic vasodilatation, severe hypovolemia, or cardiac arrest. ⋯ Vasopressin administration is emerging as a rational and promising therapy in the management of various shock states and cardiac arrest.

Evidence-based practice guidelines for interventional techniques in the management of chronic spinal pain are systematically developed and professionally derived statements and recommendations that assist both physicians and patients in making decisions about appropriate health care in the diagnosis and treatment of chronic or persistent pain. The guidelines were developed utilizing an evidence-based approach to increase patient access to treatment, to improve outcomes and appropriateness of care, and to optimize cost-effectiveness. All types of relevant and published evidence and consensus were utilized. ⋯ It is expected that a provider will establish a plan of care on a case-by-case basis, taking into account an individual patient's medical condition, personal needs, and preferences, and the physician's experience. Based on an individual patient's needs, treatment different from that outlined here could be warranted. These guidelines do not represent "standard of care."
