Thallium--201 myocardial perfusion scanning has been evaluated in Australia in patients with coronary artery disease. Myocardial scans reliably detect both acute myocardial infarction and the transient myocardial ischaemia of angina pectoris. The non-invasive nature, ease of study, and the ability to scan patients with conventional cameras makes thallium--201 an attractive additional diagnostic agent for patients with suspected coronary artery disease. Although thallium--201 reliably indicates perfusion defects in the myocardium, its diagnostic use at the moment should be reserved to clarify such diagnostic problems in patients with coronary artery disease which cannot be satisfactorily explained by conventional investigation.

Eleven cases of sickle cell disease within the Sydney area are described. Eight of these are of homozygous sickle cell anaemia, and three are of the sickle cell-thalassaemia disease. ⋯ The age of patients at diagnosis ranged from five months to 22 years, and the clinical severity from very mild to very severe, with a wide spectrum of clinical manifestations. It is concluded that sickle cell disease is already a significant health problem within the Sydney area, and likely to increase in incidence with increasing migration from endemic zones.

Campylobacter jejuni was isolated on coproculture from 13 of 224 patients with suspected infectious diarrhoea whose faecal specimens were examined during a three-month period. These organisms were not isolated from 530 specimens received from asymptomatic and healthy individuals. ⋯ Ingestion of campylobacter resulted in enteric infection with increasing numbers of campylobacter in the stool. Clinical laboratories should attempt to isolate these organisms from patients with diarrhoea.
