[2012 literature findings in ambulatory internal medicine]. / Acquisitions thérapeutiques en médecine ambulatoire en 2012.

In 2012 several articles reported interesting findings for the ambulatory practice in internal general medicine. A negative rapid test for influenza does not rule out that diagnosis. A test assessing the walking speed in the elderly can help determining who would benefit from antihypertensive therapy. Antibiotic treatment has no benefit for acute uncomplicated rhinosinusitis and diverticulitis. Probiotics can reduce the risk of post-antibiotic diarrhea. Daily coffee intake could reduce mortality. Oral supplementation of calcium can be harmful to the cardiovascular system. Subclinical hyperthyroidism should be treated to prevent cardiovascular complications. Aspirin can prevent recurrences in case of a primary thromboembolic event. Local injection of corticosteroids under ultrasonographic guidance for plantar fasciitis can be a safe treatment. Ibuprofen can prevent acute mountain sickness.

Spondylodiscitis due to Propionibacterium acnes: report of twenty-nine cases and a review of the literature.

Propionibacterium acnes is the most frequent anaerobic pathogen found in spondylodiscitis. A documented case required microbiological proof of P. acnes with clinical and radiological confirmation of inflammation in a localized region of the spine. Microbiological samplings were obtained by surgery or aspiration under radiological control. Twelve males and 17 females (median age, 42 years) with spondylodiscitis due to P. acnes were diagnosed within the last 15 years. Three patients were immunosuppressed. All patients reported back pain as the main symptom, and most were afebrile. Three patients had a peripheral neurological deficit, one a motor deficit, and two a sensory deficit attributable to the infection; and six patients had an epidural abscess. The most frequent risk factor was surgery, which was present in the history 28 of 29 (97%) patients. The mean delay between spinal surgery and onset of disease was 34 months, with a wide range of 0-156 months. Osteosynthesis material was present in twenty-two cases (76%). In 24 (83%) patients, additional surgery, such as débridement or spondylodesis, was performed. Previous osteosynthesis material was removed in 17 of the 22 (77%) patients where it was present. Total cure was reported in all patients, except one, after a mean duration of antibiotic therapy of 10.5 weeks (range, 2-28 weeks). In conclusion, spondylodiscitis due to P. acnes is an acute infection closely related to previous surgery. The most prominent clinical feature is pain, whereas fever is rare, and the prognosis is very good.
