Mucocutaneous lesions of Behcet's disease.

Behcet's disease is particularly prevalent in "Silk Route" populations, but it has a global distribution. The diagnosis of the disease is based on clinical criteria as there is as yet no pathognomonic test, and mucocutaneous lesions, which figure prominently in the presentation and diagnosis, may be considered the diagnostic hallmarks. Among the internationally accepted criteria, painful oral and genital ulcers, cutaneous vasculitic lesions and reactivity of the skin to needle prick or injection (the pathergy reaction) are considered hallmarks of Behcet's disease, and often precede other manifestations.

A benefit/risk assessment of existing therapeutic alternatives for the treatment of painful inflammatory conditions.

Pain remains the leading reason for which patients consult their doctors. Pain also motivates over-the-counter sales of analgesic medicines, to be taken orally or even transcutaneously. Prescription medicines usually follow attempts at self-medication that fail to achieve the desired results.

Low back pain.

Low back pain is a leading cause of disability. It occurs in similar proportions in all cultures, interferes with quality of life and work performance, and is the most common reason for medical consultations. Few cases of back pain are due to specific causes; most cases are non-specific.

Back pain.

Back pain is ubiquitous and probably plagues almost everyone in all cultures and ethnic groups at some time (around 20% annually), and in up to 50% of these at least once a year. The WHO-COPCORD epidemiologic investigations have established its prevalence even in countries that had been unaware of its frequency in their populace, and factors involving type of work and training probably accounted for this misperception. Medical journals are replete with articles addressing diagnosis and treatment, but the majority fail to meet the standards needed for metaanalysis or comparison.

Inhaled corticosteroids effects on bone in asthmatic and COPD patients: a quantitative systematic review.

Deleterious effect of oral corticosteroids on bone has been well documented, whereas this remains debated for inhaled ones (ICS). Our objectives were to analyze the effects of ICS on bone mineral density, fracture risk and bone markers. We performed an exhaustive systematic research of all controlled trials potentially containing pertinent data, peer-reviewed by a dedicated WHO expert group, and comprehensive meta-analyses of the data.
