Recurrent macroglossia requiring tracheostomy after haemorrhagic basal ganglia stroke.

A 50-year-old African American woman with hypertension, congestive heart failure, chronic kidney disease and prior cerebral vascular accident was transferred from an outside hospital after being found unresponsive and subsequently intubated for severe orolingual swelling. Imaging showed left thalamic haemorrhagic stroke, and the lingual swelling was clinically concerning for angio-oedema, with which a lingual biopsy was consistent. Work-up was negative for hereditary or acquired angio-oedema, and imaging was negative for structural causes. Of note, the patient had an episode of severe orolingual swelling 3 months prior to this presentation after suffering left thalamic haemorrhage which self-resolved after approximately 2 months. In both episodes lingual swelling predated receipt of tissue plasminogen activator and she had discontinued ACE inhibitor therapy since her first episode of tongue swelling. Despite medical and supportive management, tongue swelling progressed during admission and the decision was made to allow the patient's tongue swelling to self-resolve.

Balance and gait in the elderly: A contemporary review.

BACKGROUND: The prevalence of balance and gait deficits increases with age and is associated with the increased incidence of falls seen in the elderly population; these falls are associated with significant morbidity and mortality. OBJECTIVES: To review changes in gait and balance associated with aging and the effect of visual perturbations on gait and balance in the elderly to provide a basis for future research. METHODS: PubMed and Cochrane Library were searched for articles from 1980 to present pertaining to gait and balance in older adults (>60) and younger adults (<60). Search terms included balance, posture, gait, locomotion, gait variability, gait disorders, gait disturbance, elderly, aging, falls, vision, visual, vestibular, and virtual reality. The references section of queried articles was also used to find relevant studies. Studies were excluded if subjects had a diagnosed gait or balance disorder. RESULTS: Elderly adults show age-related decline in sensory systems and reduced ability to adapt to changes in their environment to maintain balance. Elderly adults are particularly dependent on vision to maintain postural stability. Distinct changes in spatiotemporal gait parameters are associated with aging, such as slower gait and increased gait variability, which are amplified with exposure to visual perturbations. Increased gait variability, specifically with mediolateral perturbations, poses a particular challenge for elderly adults and is linked to increased falls risk. Virtual reality training has shown promising effects on balance and gait. CONCLUSION: Elderly adults show age-related decline in balance and gait with increased gait variability and an associated increased risk of falls. LEVEL OF EVIDENCE: 5.
