A woman in her fifties with recurrent dizziness. / En kvinne i 50-årene med residiverende svimmelhet.

BACKGROUND: Vasculitis caused by neuroborreliosis is one of many rare described causes of stroke. CASE PRESENTATION: A female smoker in her fifties presented with dizziness due to a left cerebellar infarction, and after general stroke workup atherosclerosis was considered the probable cause. In the preceding months she had experienced nonspecific intermittent headache, neck pain and dizziness initially attributed to prior head trauma. Over the following months she presented with relapsing and additional symptoms from the posterior circulation and a new right cerebellar infarction was diagnosed. Contrast-enhanced MRI showed signs of myelitis and meningeal enhancement. CSF examination revealed leukocytes 230 · 106/L (0-4 · 106/L) with 98 % mononuclear cells, protein 3.12 g/L (0.00-0.45 g/L). Borrelia IgG and IgM antibodies were positive in serum and CSF, with ratio examinations consistent with intrathecal synthesis. She had a history of multiple tick bites, but not of erythema migrans. She had satisfactory clinical, biochemical and radiological response to antibiotic treatment with ceftriaxone. INTERPRETATION: Neuroborreliosis was considered the aetiology of her cerebellar infarctions although no definite signs of cerebral vasculitis were evident from CT angiography. Rare causes of stroke, including neuroborreliosis, should be considered in stroke patients without risk factors for cerebrovascular disease and negative primary workup, and in recurrent stroke despite secondary preventive treatment.

Medical findings in an interdisciplinary geriatric outpatient clinic specialising in falls.

BACKGROUND: Falls are common among elderly people, leading to increased morbidity and reduced quality of life. A broad-based interdisciplinary study, for example in an outpatient clinic specialising in falls, has been recommended in light of the multiple and complex causes that tend to be involved. At present there are few outpatient clinics in Norway specialising in falls, and no data from such studies have yet been published. MATERIAL AND METHOD: The information stems from 111 patients at the Fallpoliklinikken, Oslo University Hospital, from its establishment in 2008 until 2011. An interdisciplinary study was undertaken by a nurse, a doctor and a physiotherapist. Further investigations and measures were proposed on the basis of individual risk factors. RESULTS: The patient group had a number of known risk factors for falls. The most frequently identified risk factors included orthostatism (26 of 110 patients, 24%), vitamin D deficiency (14 of 79 patients, 18%) and carotid sinus hypersensitivity (6 of 55 patients examined, 11%). Rare, but significant findings included colon cancer, subdural haematoma (one case of each) and normal pressure hydrocephalus (two cases). The most frequent measures for preventing new falls included exercise/physiotherapy (close to all patients), adjustment of medications (25 patients, 23%) and implantation of a pacemaker (six patients, 5%). INTERPRETATION: Falls among elderly people have varying and complex causes and a serious underlying pathology may manifest itself as a tendency to fall. This testifies to the importance of a thorough interdisciplinary study of falls.
