(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.

Although postoperative analgesia in infants and children should be an integral part of the perioperative management, undertreatment of pain is not rare in clinical practice and may influence outcome and long term behaviour. Therefore, this review summarizes results of recent papers and discusses actual trends and future perspectives concerning postoperative pharmacologic pain therapy in infants and children. ⋯ The reviewed studies suggest that there are many reliable agents and techniques available to provide a safe and effective postoperative analgesia even in neonates and small infants.

Anaesthetic considerations in patients with chronic pulmonary disease.
Chronic pulmonary diseases are getting more important in daily anaesthetic practice, because prevalence is increasing and improved anaesthetic techniques have led to the abandonment of previous contraindications to anaesthesia. It is therefore essential for the anaesthetist to be up to date with current clinical concepts and their impact on the conduction of anaesthesia as well as new insights into how to anaesthetise these patients safely. ⋯ Assessing the functional status of patients admitted for surgery remains a difficult task, and in patients identified as being at risk by clinical examination additional spirometry and blood gas measurements may be helpful. If there are flow limitations and signs of respiratory failure, the anaesthetist should be highly alarmed and monitor the patient closely and invasively, yet there is no reason to deny any patient a substantially beneficial operation.

There are significant misunderstandings about the management of perioperative do-not-resuscitate orders. This paper reviews some of the difficulties generated by the halting acceptance and inconsistent implementation of an ethically appropriate perioperative do-not-resuscitate policy that mandates reconsideration of existing do-not-resuscitate orders. It also offers strategies for empowerment of such a policy. ⋯ A well written perioperative do-not-resuscitate policy is essential for surmounting obstacles to a well functioning perioperative do-not-resuscitate system.

The purpose of this current opinion on sacroiliac joint pain and dysfunction is to assist interventional pain physicians to apply appropriate treatment decisions and rationale to their patients in pain. Discussion of relevant scientific data and controversial positions will be provided. ⋯ Discussion will provoke support or criticism of the relevant scientific data, and general recommendations for interventional pain management physicians should be considered within the context of the individual practitioners skill and practice patterns. Current Opinion is not intended to provide a standard of care.
