Randomized Controlled Trial
Pharmacokinetics and bioavailability of oxycodone and acetaminophen following single-dose administration of MNK-795, a dual-layer biphasic IR/ER combination formulation, under fed and fasted conditions.
XARTEMIS™ XR (formerly MNK-795) is a combination oxycodone (OC) and acetaminophen (APAP) analgesic with both immediate-release and extended-release (ER) components (ER OC/APAP). The tablets are designed with gastric-retentive ER oral delivery technology that releases the ER component at a controlled rate in the upper gastrointestinal tract. Because consumption of food has demonstrated an impact on the pharmacokinetics (PK) of some marketed products using gastric-retentive ER oral delivery technology, a characterization of the effects of fed (high- and low-fat diets) versus fasted conditions on the PK of ER OC/APAP was performed. ⋯ The findings from this study suggest that ER OC/APAP can be administered with or without food.

Randomized Controlled Trial Comparative StudyEffect of preoperative acetaminophen/hydrocodone on the efficacy of the inferior alveolar nerve block in patients with symptomatic irreversible pulpitis: a prospective, randomized, double-blind, placebo-controlled study.
The purpose of this prospective, randomized, double-blind, placebo-controlled study was to determine the effect of the administration of the combination acetaminophen/hydrocodone on the anesthetic success of mandibular posterior teeth in patients experiencing symptomatic irreversible pulpitis. ⋯ A combination dose of 1000 mg acetaminophen/10 mg hydrocodone given 60 minutes before the administration of the IAN block did not result in a statistically significant increase in anesthetic success for mandibular posterior teeth in patients experiencing symptomatic irreversible pulpitis.

Randomized Controlled Trial Clinical TrialOpioid-sparing effect of intravenous paracetamol after percutaneous nephrolithotomy: a double-blind randomized controlled trial.
To evaluate meperidine-sparing effect of intravenous (IV) paracetamol in patients undergoing percutaneous nephrolithotomy (PCNL). ⋯ In this study, IV paracetamol significantly reduced total meperidine consumption and pain intensity scores compared with placebo. IV paracetamol can be an effective and safe part of multimodal analgesia regimes for postoperative pain management after PCNL.

Case Reports
Acetaminophen-induced anion gap metabolic acidosis secondary to 5-oxoproline: a case report.
5-oxoproline (pyroglutamic acid), an organic acid intermediate of the gamma-glutamyl cycle, is a rare cause of high anion gap metabolic acidosis. Acetaminophen and several other drugs have been implicated in the development of transient 5-oxoprolinemia in adults. We believe that reporting all cases of 5-oxoprolinemia will contribute to a better understanding of this disease. Here, we report the case of a patient who developed transient 5-oxoprolinemia following therapeutic acetaminophen use. ⋯ 5-oxoproline acidosis is an uncommon cause of high anion gap metabolic acidosis; however, it is likely that it is under-diagnosed as awareness of the condition remains low and testing can only be performed at specialized laboratories. The diagnosis should be suspected in cases of anion gap metabolic acidosis, particularly in patients with recent acetaminophen use in combination with sepsis, malnutrition, liver disease, pregnancy or renal failure. This case has particular interest in medicine, especially for the specialties of nephrology and orthopedics. We hope that it will add more information to the literature about this rare condition.

Fever, hyperglycemia, and swallow dysfunction poststroke are associated with significantly worse outcomes. We report treatment and monitoring practices for these three items from a cohort of acute stroke patients prior to randomization in the Quality in Acute Stroke Care trial. ⋯ Our results showed that acute stroke patients were: undermonitored and undertreated for fever and hyperglycemia; and underscreened for swallowing dysfunction and unnecessarily reassessed by a speech pathologist, indicating the need for urgent behavior change.
