A continuous morphine infusion—standard postoperative analgesic therapy in infants—is associated with adverse effects such as respiratory depression. To examine whether intravenous paracetamol (acetaminophen) could reduce the postoperative morphine requirement, Ceelie and colleagues randomly assigned 71 infants who underwent major noncardiac surgery to postoperative continuous morphine or intermittent intravenous paracetamol—with rescue morphine administered to both groups as needed. The authors report that postoperative use of intravenous paracetamol was associated with a lower cumulative morphine dose in the first 48 postoperative hours. In an editorial, Anand discusses efficacy and safety of intravenous paracetamol in infants and children.
To assess whether vitamin D supplementation might reduce symptoms and structural progression of knee osteoarthritis, McAlindon and colleagues randomly assigned 146 patients with symptomatic knee osteoarthritis to receive either oral cholecalciferol (2000 IU daily with dose escalation to achieve a target 25-hydroxyvitamin D serum level >36 ng/mL) or placebo for 2 years. The authors report that compared with placebo, vitamin D supplementation for 2 years did not reduce knee pain or cartilage volume loss.

In a retrospective cohort study that involved 291 patients in Toronto, Canada, who tested positive for Neisseria gonorrhoeae infection and were treated with cefixime, Allen and colleagues found a relatively high rate of treatment failure—defined as isolation of N gonorrhoeae at a test-of-cure visit identical to the pretreatment isolate with denial of sexual reexposure—associated with elevated minimum inhibitory concentrations to cefixime. In an editorial, Kirkcaldy and colleagues discuss the threat of drug-resistant gonorrhea.
Ms A, a 60-year-old teacher, reported acute-onset shortness of breath associated with an inability to walk more than a short distance. She was transported to a hospital. On physical examination, her blood pressure was 156/72 mm Hg, and a computed tomographic angiogram showed a large saddle pulmonary embolus in the distal left pulmonary artery and evidence of right ventricular dysfunction—findings consistent with submassive pulmonary embolism. Piazza discusses the diagnosis and treatment of this high-risk phenotype of acute pulmonary embolism.
New-onset dyspnea and altered sensorium resulted in hospital admission for a 46-year-old man who was receiving chronic hemodialysis. He was noted to have “milky” secretions draining from a hip wound. A hip radiograph showed bulky, extra-articular calcifications. Echocardiography revealed a mitral valve mass. Initial laboratory results included leukocytosis; calcium, 7.6 mg/dL; phosphorous, 8.9 mg/dL; and albumin, 2.4 g/dL. What would you do next?
