Persistent pain represents a major quality-of-life burden for patients and a challenge for their physician. Chronic pain often arises from multiple tissue sources and involves multiple chemical mediators and pain transmission pathways. Successful long-term pain management requires analgesic regimens that can treat pains of multiple origin and type. ⋯ Rational combinations of analgesic drugs offer a viable approach to managing persistent pain that involves multiple sites or pathways. The combination of paracetamol plus tramadol brings together two well-known analgesics that have different but complementary mechanisms of analgesic action. Laboratory studies have demonstrated that these agents interact to produce synergistic analgesia with a desirable safety/efficacy profile.

Pain is a leading cause of morbidity worldwide, with published data showing its prevalence as high as 50% for chronic pain in the European population. This prevalence is likely to continue to rise, particularly in elderly people with comorbid conditions and complex aetiologies of pain. There is thus a rapidly growing demand for safe and effective pain management. ⋯ Fixed-dose combinations of paracetamol with weak opioids, such as codeine, dextropropoxyphene or tramadol are currently available. Paracetamol plus tramadol is an effective and safe multimodal analgesic regimen for the management of both acute and chronic moderate-to-severe pain. Re-evaluating the role of weak opioids, such as tramadol, and combinations in pain management may prove a valuable option for prescribers seeking alternatives to anti-inflammatory drugs.

ReviewCOX-2-Specific inhibitors--the emergence of a new class of analgesic and anti-inflammatory drugs.
The prostaglandin series of bioactive compounds is formed by the interaction of two distinct but related enzymes, cyclo-oxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2). COX-1 is a constitutive form which is present mainly in the gastric mucosa, kidney and platelets. COX-2 is mainly an inducible form, although also to some extent present constitutively in the CNS, the juxtaglomerular apparatus of the kidney and in the placenta during late gestation. ⋯ Compared to the traditional and non-selective NSAIDs, COX-2 inhibitors may provide an insight into additional therapeutic areas, such as gastrointestinal cancer and dementia, where the potential relevance to COX-2 mechanisms are currently being explored and clinical trials being performed. With the rapid clinical acceptance of celecoxib and rofecoxib, knowledge about their clinical usefulness in various inflammatory disease states and pain disorders is increasing. For the many patients suffering from such conditions, the selective COX-2 inhibitors are likely to become a significant addition to the therapeutic arsenal of analgesic and anti-inflammatory drugs.

Review Case ReportsTenosynovitis due to Mycobacterium avium intracellulare and Mycobacterium chelonei: report of two cases with review of the literature.
Atypical mycobacteria can induce soft tissue infections such as tenosynovitis. We observed one case of finger flexor tendon tenosynovitis infected with Mycobacterium avium intracellulare and one case of knee and ankle arthritis with lateral peroneal tendon tenosynovitis due to M. chelonei. ⋯ This patient died from infectious pneumonitis. Previously reported cases of infectious tenosynovitis due to these atypical mycobacteria are reviewed.

Review Case ReportsHypocalcaemia and chronic alcohol intoxication: transient hypoparathyroidism secondary to magnesium deficiency.
The authors report the observation of an alcoholic patient admitted for tetanic manifestations, in whom severe hypocalcaemia associated with hyperphosphatemia were suggestive of hypoparathyroidism. Administration of magnesium supplementation alone improved the clinical features and led to the correction of the calcium abnormalities. The mechanisms of hypomagnesemia in alcohol intoxication are reviewed as well as the links with hypocalcaemia.
