RESUMEN
Published studies on the epidemiology of amyloidosis have relied on death certificate data for case ascertainment. We estimated the incidence and mortality burden of amyloidosis among residents of the Australian state, Queensland, aged ≥20 years for the years 1999-2013 based on case ascertainment from histopathology reports. Information systems for participating laboratories were scrutinised to identify histopathology reports that documented a diagnosis of amyloidosis. Case mortality status was determined via linkage to the National Death Index. A total of 447 cases of amyloidosis were identified, with a median age at diagnosis of 66 years. A plasma cell dyscrasia was identified in 72% of patients who had paraprotein studies performed. The estimated incidence for Queenslanders aged ≥20 years was 12·1 cases per million person years. The median survival was 2·45 years. Age at diagnosis, presence of a paraprotein, earlier year of diagnosis, and inner regional location of residence (compared with residence in a major city) were independently associated with reduced survival. Our data confirms previously reported incidence data for amyloidosis of approximately 10 cases per million patient years and indicates that survival for Queensland patients with amyloidosis is improving, though it remains poor for the elderly and patients with AL amyloidosis.

Ischemic heart disease and stroke are the leading causes of mortality worldwide according to the World Health Organization. Hypertension is a major factor in the development of these diseases. Olmesartan is an angiotensin II receptor blocker (ARB) indicated in the treatment of hypertension. There are several case reports describing sprue-like enteropathy caused by olmesartan. We report on a 72-year-old patient referred to our hospital for work-up of chronic diarrhoea, vomiting and weight-loss, and villous atrophy on intestinal biopsy. The patient's symptoms abated upon cessation of olmesartan. This case illustrates the need for a thorough medication history and regular review during work-up. We hope it will add to the current understanding of this rare phenomenon.
RESUMEN
A 60 year old lady was referred to the Princess Alexandra Hospital (Brisbane, Queensland, Australia) tertiary Otolaryngology, Head and Neck Unit from a peripheral hospital for investigation and management of a tumour at the base of the tongue. Biopsy of the tumour revealed it to be an epithelial-myoepithelial carcinoma of the base of the tongue. This is an extremely rare tumour in this location with only 2 other case reports in the world literature: the patients were treated with chemo-radiotherapy and surgery respectively. Our patient was made aware of the world literature and was able to make a fully informed decision on her choice of treatment modality and was treated with radiotherapy. Increasingly journals are limiting publication of case reports to "world firsts" only. We present a case where such a policy would have denied patient choice and possibly led to detrimental treatment.We review the world literature of tongue base epithelial-myoepithelial carcinoma of the tongue.
