Randomized Controlled TrialThe effect of cisatracurium and rocuronium on lung function in anesthetized children.
Neuromuscular blocking drugs have been implicated in intraoperative bronchoconstrictive episodes. We examined the effects of clinically relevant doses of cisatracurium and rocuronium on the lung mechanics of pediatric subjects. We hypothesized that cisatracurium and rocuronium would have bronchoconstrictive effects. ⋯ At clinically relevant doses, both cisatracurium and rocuronium caused changes in lung function, indicating constriction of smaller airways. In general, these changes were mild and not clinically detectable. However, in the rocuronium group, 3 of 13 patients showed more noticeable decreases in MEF10 (≤50%), demonstrating the potential for significant broncho-bronchiolar constriction in susceptible patients.

Comparative Study Observational Study
Comparison of clinical burden between patients with erosive hand osteoarthritis and inflammatory arthritis in symptomatic community-dwelling adults: the Keele clinical assessment studies.
To investigate in the general population the clinical impact of erosive OA in interphalangeal joints (IPJs) compared with symptomatic radiographic hand OA and inflammatory arthritis. ⋯ While erosive OA has a greater impact than symptomatic radiographic hand OA in the general population, it is not as severe in terms of hand pain and disability as inflammatory RA.

Sleep and headache have both generated curiosity within the human mind for centuries. The relationship between headache and sleep disorders is very complex. While Lieving in 1873 first observed that headaches were linked to sleep, Dexter and Weitzman in 1970 described the relationship between headache and sleep stages. ⋯ Patient education and lifestyle modification play a significant role in overall success of the treatment. Chronic tension-type headache and chronic migraine have high prevalence of insomnia and comorbid psychiatric disorders, which require behavioral insomnia treatment and medication if needed along with psychiatric evaluation. Apart from the abortive treatment tailored to the headache types, - such as triptans and DHE 45 for migraine and nonsteroidal anti-inflammatory medication for chronic tension-type headache, preventive treatment with different class of medications including antiepileptics (Topamax and Depakote), calcium channel blockers (verapamil), beta blockers (propranolol), antidepressants (amitriptyline), and Botox may be used depending upon the comorbid conditions.

Comparative StudyAnesthetic induction with etomidate, rather than propofol, is associated with increased 30-day mortality and cardiovascular morbidity after noncardiac surgery.
Because etomidate impairs adrenal function and blunts the cortisol release associated with surgical stimulus, we hypothesized that patients induced with etomidate suffer greater mortality and morbidity than comparable patients induced with propofol. ⋯ Etomidate was associated with a substantially increased risk for 30-day mortality, cardiovascular morbidity, and prolonged hospital stay. Our conclusions, especially on 30-day mortality, are robust to a strong unmeasured binary confounding variable. Although our study showed only an association between etomidate use and worse patients' outcomes but not causal relationship, clinicians should use etomidate judiciously, considering that improved hemodynamic stability at induction may be accompanied by substantially worse longer-term outcomes.

ReviewMeasuring renal function in critically ill patients: tools and strategies for assessing glomerular filtration rate.
Alterations in kidney function are common in critically ill patients and are generally assessed by changes in serum creatinine (sCr) or urine output, which are considered surrogates for glomerular filtration rate (GFR) but do not reflect the overall kidney function. There is a great need for more reliable measurements of glomerular filtration in order to guide diagnosis and therapy for acute kidney injury. In this review, we will focus on recent advances to measure GFR that could help to better evaluate kidney function and improve patient care. ⋯ Standardized assays for sCr measurements, the use of a more precise scale with more frequent measurements, and the interpretation of the results based on patient's characteristics can increase the clinical value of sCr. New endogenous and exogenous markers will provide a more precise estimation. Imaging techniques are being developed and will probably be available in the near future. New gold standards for glomerular filtration will help in the development and improvement in the use of new biomarkers of kidney injury.
