Randomized Controlled Trial Comparative StudyEfficacy of Ibuprofen and ibuprofen/acetaminophen on postoperative pain in symptomatic patients with a pulpal diagnosis of necrosis.
The purpose of this prospective, randomized, double-blind study was to determine ibuprofen versus ibuprofen/acetaminophen use for postoperative endodontic pain in symptomatic patients with a pulpal diagnosis of necrosis and an associated periapical radiolucency who were experiencing moderate to severe preoperative pain. We also recorded escape medication use. ⋯ There were decreases in pain levels and analgesic use over time for the ibuprofen and ibuprofen/acetaminophen groups. There was no statistically significant difference between the 2 groups for analgesic use or escape medication use. Approximately 20% of patients in both groups required escape medication to control pain.

Randomized Controlled TrialExplaining the acetaminophen-ibuprofen analgesic interaction using a response surface model.
The value of acetaminophen-ibuprofen combination therapy over single therapy is uncertain in acute pediatric pain management. A model describing the interaction between these two drugs would be useful both for understanding current literature and for future study design. ⋯ This drug interaction modeling example is useful to explain combination therapy nuances and impacts on study design. Differences in effect between single drug therapy and combination therapy should be sought at lower doses and beyond the immediate postoperative period. Combination therapy may prolong the duration of analgesia. The maximum effect (E(MAX) ) limits the early additional analgesic gain from combination therapy beyond commonly used doses.

Randomized Controlled TrialThe effects of preoperative intravenous acetaminophen in patients undergoing abdominal hysterectomy.
Although intravenous acetaminophen is commonly used for the management of postoperative pain, very limited evidence supports the usefulness of preoperative administration. The aim of this study was to determine the analgesic effect of preoperative acetaminophen on opioid consumption, pain scores, and side effects in patients receiving an elective abdominal hysterectomy. ⋯ Premedication with acetaminophen reduced hydromorphone consumption and opioid-related side effect in patients undergoing abdominal hysterectomy, but did not significantly reduce pain intensity.

Randomized Controlled Trial Comparative Study
A prospective randomized study to evaluate the antipyretic effect of the combination of acetaminophen and ibuprofen in neurological ICU patients.
To compare the antipyretic effect of simultaneously administered acetaminophen (APAP) plus ibuprofen (IBU) to either APAP or IBU alone in critically ill febrile neurological and neurosurgical patients. ⋯ The combination of IBU and APAP produces significantly greater fever control than APAP alone, with trends favoring the combination over IBU alone and IBU over APAP alone.

Case Reports
Delayed and prolonged elevated serum paracetamol level after an overdose - possible causes and implications.
We report the case of a 29-year-old man who ingested about 50 g of standard-preparation paracetamol plus other medications. The serum paracetamol level remained low in the first 24 hours. It peaked 54 hours after ingestion and remained high for 5 days. ⋯ On Day 3, the patient's liver function deteriorated and a rising serum paracetamol level was noted; hence, an NAC infusion was reinitiated. Despite this, the patient developed fulminant hepatic failure. This case underlines the importance of monitoring paracetamol levels and liver function for at least 72 hours after a suspected large overdose of paracetamol before discontinuing NAC infusion.
