Randomized Controlled Trial
Efficacy of multimodal perioperative analgesia protocol with periarticular medication injection in total knee arthroplasty: a randomized, double-blinded study.
Pain control is necessary for successful rehabilitation and outcome after total knee arthroplasty. Our goal was to compare the clinical efficacy of periarticular injections consisting of a long-acting local anesthetic (ropivacaine) and epinephrine with and without combinations of an α2-adrenergic agonist (clonidine) and/or a nonsteroidal anti-inflammatory agent (ketorolac). ⋯ Compared with Group D, Group A and B patients had significantly lower postoperative visual analog pain scores and nurse pain assessment and Group C patients had a significantly greater reduction in physical therapist pain assessment. We found no differences in other parameters analyzed.

The best predictor of good outcome after cardiac arrest is awakening from coma. The longer it takes to regain consciousness, the greater the risk of permanent brain injury. A reliable neurological assessment could previously be performed on day 3 after arrest; absence of or a stereotypic motor reaction to pain and absence of cranial nerve reflexes were reliable predictors of poor outcome, but this has changed. ⋯ This is probably due to increased use of sedative drugs and delayed metabolism during hypothermia but could, in addition, be explained by delayed maturation and recovery processes of brain ischaemia. A clinical neurological assessment should no longer be the sole decisive method for prognostication after cardiac arrest. Instead, a clinical investigation should be used in combination with independent and objective methods, above all neurophysiology (electroencephalography and somatosensory evoked potentials), while biomarkers and brain imaging may be valuable adjuncts.

Few studies have investigated the implications of intracerebral hematoma (ICH) due to rupture of a middle cerebral artery (MCA) aneurysm and patient outcomes. We hypothesized that patients with Hunt-Hess (HH) grade IV-V may not benefit from aggressive measures. ⋯ Aggressive clip ligation and hematoma evacuation remains a reasonable option for patients suffering from an ICH associated with a ruptured MCA aneurysm. Admission HH grade is the primary prognostic factor for outcome among this patient population as more than half of patients with HH grade IV and V expired during their hospitalization despite aggressive treatment of their hematoma and aneurysm. Long-term functional outcome was poor in up to 85% of surviving patients with HH grade IV-V. It may be beneficial to discuss these prognostic factors with the family before implementing aggressive measures.

Multicenter StudyRevision from unicompartmental to total knee replacement: the clinical outcome depends on reason for revision.
Although it has been suggested that the outcome after revision of a unicondylar knee replacement (UKR) to total knee replacement (TKR) is better when the mechanism of failure is understood, a comparative study on this subject has not been undertaken. A total of 30 patients (30 knees) who underwent revision of their unsatisfactory UKR to TKR were included in the study: 15 patients with unexplained pain comprised group A and 15 patients with a defined cause for pain formed group B. The Oxford knee score (OKS), visual analogue scale for pain (VAS) and patient satisfaction were assessed before revision and at one year after revision, and compared between the groups. ⋯ There was a statistically significant difference between the mean improvements in each group for both OKS (p = 0.022) and VAS (p = 0.002). Subgroup analysis in group A, performed in order to define a patient factor that predicts outcome of revision surgery in patients with unexplained pain, showed no pre-operative differences between both subgroups. These results may be used to inform patients about what to expect from revision surgery, highlighting that revision of UKR to TKR for unexplained pain generally results in a less favourable outcome than revision for a known cause of pain.

ReviewFibroblast growth factor-23: what we know, what we don't know, and what we need to know.
Traditional risk factors of cardiovascular morbidity and mortality such as hypertension, hypercholesterolemia and obesity are paradoxically associated with better outcomes in dialysis patients, and the few trials of interventions targeting modifiable traditional risk factors have yielded disappointing results in this patient population. Non-traditional risk factors such as inflammation, anemia and abnormalities in bone and mineral metabolism have been proposed as potential explanations for the excess mortality seen in patients with chronic kidney disease (CKD) and end-stage renal disease (ESRD), but without clear understanding of what the most important pathophysiologic mechanisms of these risk factors are, which ones might be ideal treatment targets and which therapeutic interventions may be effective and safe in targeting them. Among the novel risk factors, fibroblast growth factor-23 (FGF23) has recently emerged as one of the most powerful predictors of adverse outcomes in patients with CKD and ESRD. ⋯ While it is possible that 'off target' effects of FGF23 present in very high concentrations could induce LVH, this possibility is controversial, since α-klotho is not expressed in the myocardium. Another possibility is that FGF23's effect on the heart is mediated indirectly, via 'on target' activation of other humoral pathways. We will review the physiology and pathophysiology of FGF23, the outcomes associated with elevated FGF23 levels, and describe putative mechanisms of action responsible for its negative effects and potential therapeutic strategies to treat these.
