Comparative Study
[How to determine the diagnosis of Helicobacter pylori infection in the elderly?].
The real prevalence of Helicobacter pylori (H. pylori) infection is difficult to determine in the elderly because of the frequency of drug intake (antibiotics or anti-secretory drugs). The aim of this study was to evaluate the diagnostic performance of five tests in the elderly. ⋯ Diagnostic performances decreased in older patients especially because of drug intake.

The cluster headache (CH) is one of the most severe types of head pain. It is a typical example of a periodic disease and the International Headache Society classification recognizes two forms of this disease: episodic and chronic CH. Its prevalence is about 0.1 to 0.4% in the general population. ⋯ Contraindications and side-effects of the drugs limit the choice of the prophylactic treatment: corticosteroids in a tapering course, verapamil and methysergide are the most useful treatments of the episodic form. Lithium carbonate is more effective for the chronic stage of CH, but side-effects are often troublesome. Numerous other medications have been used for prophylaxis: valproate, capsaicin, beta-blockers. Unfortunately, double-blind studies are often lacking and are difficult to realize due to spontaneous variable remission of episodic CH. When adequate trials of drug therapies show a total resistance to the treatments, surgery may be considered. Radiofrequency trigeminal rhizotomy is the treatment of choice with 70% of beneficial effects. Risks and complications have to be discussed in balance with the benefit of the different surgical procedures.

Henoch-Schonlein purpura is a rare eventuality in adulthood. Abdominal involvement can worsen the short-term prognosis and justify medical treatment to avoid surgery. ⋯ Abdominopelvic CT scan demonstrated signs suggestive of intestinal vasculitis. An underlying neoplasia or an eventual other cause of abdominal pain were explored and a steroid therapy was then began with a good outcome. Abdominal CT can be helpful in the diagnosis of abdominal involvement in Henoch-Schonlein purpura.

Primary meningococcal arthritis is a rare form of meningococcal disease. It occurs as an isolated acute purulent arthritis without meningitis, and presence of Neisseria meningitidis in articular fluid. We report a new case of typical primary meningococcal arthritis. ⋯ We emphasize the fact that agar cultures of the synovial fluid remained sterile, while N. meningitidis grew in a blood-culture vial. We suggest that diagnosis of primary meningococcal arthritis may be underestimated when inappropriate culture media are used.
