RESUMO
As residents work disparate schedules at multiple locations and because of workweek hour limits mandated by the ACGME, residents may be unable to attend lectures, seminars, or other activities that would enhance their skills. Further, the ACGME requires that residency programs document resident learning in six stated core competencies and provide proof of completion for various other requirements. LMS/LC is a promising technology to provide a means by which residency programs may overcome these obstacles. More studies are needed to show under what conditions an LMS/LC program actually enhances learning, and which elements are most useful to the new generation of learners comfortable with Web 2.0 technologies.

Objective: Problem-based charting (PBC) is a method for clinician documentation in commercially available electronic medical record systems that integrates note writing and problem list management. We report the effect of PBC on problem list utilization and accuracy at an academic intensive care unit (ICU). Materials and Methods: An interrupted time series design was used to assess the effect of PBC on problem list utilization, which is defined as the number of new problems added to the problem list by clinicians per patient encounter, and of problem list accuracy, which was determined by calculating the recall and precision of the problem list in capturing 5 common ICU diagnoses. Results: In total, 3650 and 4344 patient records were identified before and after PBC implementation at Stanford Hospital. An increase of 2.18 problems (>50% increase) in the mean number of new problems added to the problem list per patient encounter can be attributed to the initiation of PBC. There was a significant increase in recall attributed to the initiation of PBC for sepsis (ß = 0.45, P < .001) and acute renal failure (ß = 0.2, P = .007), but not for acute respiratory failure, pneumonia, or venous thromboembolism. Discussion: The problem list is an underutilized component of the electronic medical record that can be a source of clinician-structured data representing the patient's clinical condition in real time. PBC is a readily available tool that can integrate problem list management into physician workflow. Conclusion: PBC improved problem list utilization and accuracy at an academic ICU.

Staphylococcus aureusbacteraemia (SAB) remains a complex disease with a high associated morbidity and mortality, especially when it is able to establish an occult nidus safe from antimicrobial eradication. Without rapid identification and intervention, the nidus can cause persistent relapse of disease, morbidity and mortality. Having a high clinical suspicion for the foci of occult S. aureus is important, and awareness of potential sites of infection is critical and can be life-saving.We present a unique case of a 65-year-old man with end-stage renal disease receiving haemodialysis who developed septic shock from SAB. Despite 18 days of appropriate antibiotics, the patient had persistent high-grade bacteraemia until his gall bladder was ultimately percutaneously drained. The day after drainage, he cleared his blood cultures, although he ultimately passed away as he decided to transition his care to focus on comfort measures.

Acute and chronic exposure to opioids has been associated with hyperalgesia in both animals and humans. A genetic analysis of opioid-induced hyperalgesia in mice linked the ß(2)-adrenergic receptor to mechanical sensitization after opioid exposure. In humans, expansion of the area of mechanical hyperalgesia surrounding an experimentally induced lesion after the cessation of remifentanil infusion is a commonly used model of opioid hyperalgesia (remifentanil-induced postinfusion hyperalgesia, RPH). The purpose of our translational study was to test the hypothesis that the ß-adrenergic receptor antagonist propranolol modulates the expression of RPH in humans. This double-blinded, randomized, placebo-controlled, crossover study was performed in 10 healthy human volunteers. During test sessions, intracutaneous electrical stimulation was used to generate areas of secondary mechanical hyperalgesia. The area of this sensitization was measured before, during, and after remifentanil infusion. Heat pain sensitivity was also followed. During one test session, subjects received propranolol infusion. We observed an average increase in the areas of secondary mechanical hyperalgesia to 141% of the baseline in subjects infused with remifentanil and placebo (P=0.00040). However, when remifentanil infusion was combined with propranolol, the area of secondary hyperalgesia after terminating remifentanil was not significantly different than the area before beginning the opioid infusion (P=0.13). Thermal hyperalgesia was not observed after remifentanil infusion. Propranolol infusion at the selected dose had minor hemodynamic effects. Concomitant infusion of propranolol with remifentanil prevented the expression of RPH. ß-adrenergic receptor blockade may be a useful pharmacological strategy for preventing hyperalgesia in patients exposed to opioids.
