Research to identify whether dizziness is a geriatric syndrome has largely overlooked often treatable vestibular causes. To ascertain the degree to which vestibular and other causes of dizziness interact in older people, an eight-month retrospective case-note review was undertaken in patients aged ≥: 65 years referred with dizziness or imbalance to an audiovestibular medicine clinic. Of 41 patients aged 65-93 years old, 15 (37%) had multiple symptom triggers, 23 (56%) had recent dizziness-related falls, 24 (59%) and 10 (24%) had peripheral and central vestibular causes for dizziness respectively, whereas 6 (15%) had both. ⋯ Polypharmacy, orthostatic hypotension, psychotropic drug use and anxiety were common contributory factors. Vestibular causes of dizziness contribute to a multifactorial geriatric syndrome. All patients with dizziness and falls should have a vestibular assessment (especially peripheral) to improve quality of life and reduce falls.

Brucella and Coxiella are similar; both are obligate intracellular, zoonotic pathogens with a broad geographic distribution. Infection in animals is usually asymptomatic, but causes fetal loss and therefore has significant economic impact. ⋯ Therefore, infection is most commonly diagnosed by serology, but this may be negative in early infection and serology results may be challenging to interpret. Both Brucella and Coxiella are typically susceptible to a wide range of antimicrobials, but long courses may be needed.

Schistosomiasis is one of the major parasitic diseases of the tropics, causing acute and long-term clinical syndromes. Almost all schistosomiasis is now imported from sub-Saharan Africa. This article summarises the aetiology, clinical presentation, diagnosis and management of schistosomiaisis for clinicians in non-endemic countries.

Human African trypanosomiasis (HAT) or sleeping sickness is a parasitic disease, acquired by the bite of an infected tsetse fly. In non-endemic countries HAT is rare, and therefore the diagnosis may be delayed leading to potentially fatal consequences. In this article the clinical presentation, diagnosis and treatment of the two forms of HAT are outlined. Rhodesiense HAT is an acute illness that presents in tourists who have recently visited game parks in Eastern or Southern Africa, whereas Gambiense HAT has a more chronic clinical course, in individuals from West or Central Africa.
