Randomized Controlled Trial Clinical TrialRisk factors for acetaminophen and nimesulide intolerance in patients with NSAID-induced skin disorders.
Previous studies show skin reactions after exposure to acetaminophen and/or nimesulide to occur in about 10% of patients with a history of urticaria induced by aspirin or other nonsteroidal anti-inflammatory drugs (NSAIDs). This fact is surprising since cross-reactivity among different NSAIDs should not occur among subjects without a history of chronic urticaria. ⋯ In at least 20% of patients with a history of urticaria/angioedema or anaphylaxis induced by aspirin or other NSAIDs, but without a history of chronic urticaria, cross-reactivity with other NSAIDs occurs. Atopy as well as a history of aspirin-induced anapylactoid reactions seem to represent relevant risk factors for intolerance to alternative NSAIDs. In view of these findings, aspirin-intolerant patients with such clinical features should be submitted to peroral tolerance tests with at least two alternative substances in order to avoid potentially severe reactions.

[Side-effects of N-acetylcysteine treatment in patients with paracetamol poisoning].
Treatment of paracetamol intoxication with N-acetylcysteine (NAC) is standard in Denmark. NAC is considered safe with relatively few side effects. It is recommended that all patients be treated irrespective of paracetamol dose or time from intoxication to treatment start. ⋯ In all cases the recommended treatment with antihistamine or steroids against adverse effects was administered. We conclude that treatment with NAC is safe. Accordingly we find no reason to change the recommendation for treatment of paracetamol intoxication in Denmark.

Randomized Controlled Trial Clinical Trial
Analgesic efficacy of paracetamol and diclofenac in children receiving PCA morphine.
We studied 80 children, aged 5-13 yr, who received PCA with morphine after appendicectomy using a standardized tracheal general anaesthetic. All patients received morphine 0.1 mg kg-1 before surgical incision and all had wound infiltration with bupivacaine 1 mg kg-1 at the end of surgery. ⋯ Analgesia, as assessed by movement pain scoring, was significantly improved by the addition of diclofenac despite lower morphine consumption. Adverse effects and duration of PCA were comparable in the four groups.
