Comparative Study Clinical Trial
Ibuprofen in the treatment of postoperative pain.
The site and type of operation and the age of the patient help determine the intensity of postoperative pain and the level of medication necessary for relief. Controlled clinical trials have shown that ibuprofen (Motrin) is an effective and safe analgesic for patients with mild to moderate postoperative pain. In a study of 120 patients with postoperative orthopedic pain, ibuprofen was more effective than acetaminophen-codeine and had a longer duration of action.

Ibuprofen (Motrin, Upjohn) was evaluated in five studies using the Dental Pain Model, which is representative of most acute postsurgical pain situations. Ibuprofen 400 mg was consistently more effective than aspirin 650 mg, acetaminophen 600 mg, and both aspirin and acetaminophen when combined with codeine 60 mg. In two studies, ibuprofen 400 mg was at least as effective as zomepirac sodium 100 mg. No serious or prolonged side effects were reported in any of these studies.

Differences in the vascular response to burn and freeze injuries were investigated as a model for defining the mechanism and cause of vascular occlusion in rats after dermal burns. Concentrations of thromboxane and prostacyclin in wound fluid were elevated in both types of trauma. ⋯ Ibuprofen promoted vascular patency even when given six hours after burn trauma. These studies indicate that ibuprofen and imidazole promote vascular patency by fostering fibrinolysis rather than by inhibiting prostaglandin synthesis and release.

Review Case Reports
Central nervous system infections associated with hereditary hemorrhagic telangiectasia.
The clinical courses of 31 episodes of brain abscess and one episode of meningitis occurring in patients with hereditary hemorrhagic telangiectasia are reviewed. Pulmonary arteriovenous malformations were demonstrable in all but two patients and presumably permitted septic microemboli to evade the normal pulmonary capillary filter and lodge in the brain. Obtundation, headache, visual disturbances, hemiplegia, and seizures were the most common presenting features. ⋯ Anaerobic and microaerophilic streptococci were the commonest pathogens found in the brain abscesses. Thirteen patients died, and patients without abscess drainage or with delayed diagnosis had a higher mortality rate. A brain abscess may develop in approximately 1 percent of patients with hereditary hemorrhagic telangiectasia, and awareness of this risk should lead to early investigation of any patient with hereditary hemorrhagic telangiectasia who has neurologic symptoms.
