Comparative StudyDiagnostic utility of endobronchial ultrasound-guided transbronchial needle aspiration compared with transbronchial and endobronchial biopsy for suspected sarcoidosis.
Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is an accurate and minimally invasive technique that has been shown to have excellent diagnostic yield in the investigation of mediastinal and hilar lymphadenopathy. There is, however, little evidence comparing this procedure to the traditional diagnostic approach of transbronchial lung (TBLB) and endobronchial (EB) biopsies combined with characteristic clinical and radiological features in sarcoidosis. ⋯ Endobronchial ultrasound-guided transbronchial needle aspiration alone has a high diagnostic yield with a very low complication rate for patients with suspected sarcoidosis.

Access to the kidney transplant waiting list: a time for reflection.
The limited availability of deceased donor kidneys for transplantation in Australia continues to be a matter of concern. Analysis of registry data suggests that the current renal transplant waiting list under-represents the real demand for three reasons. Firstly, a very low proportion of dialysis patients across all age groups are wait-listed for kidney transplantation; secondly, the percentage of dialysis patients listed for transplantation has fallen over time across all Australian states and territories; and thirdly, the number of patients wait-listed varies significantly across the country. We explore possible reasons for these issues and call for new eligibility criteria that are both transparent and justifiable and balance equity and utility.

Initiating allopurinol therapy: do we need to know the patient's human leucocyte antigen status?
Allopurinol hypersensitivity (AH) can rarely be manifest as Stevens-Johnson syndrome (SJS) or toxic epidermal necrolysis (TEN) that have high mortality rates. Less serious, but still significant, skin and systemic hypersensitivity reactions form part of the AH spectrum. One hundred per cent of Han Chinese with SJS/TEN due to allopurinol have been found to be at least heterozygous for HLA-B*5801, the carriage rate for this allele in the Han Chinese population being about 15%. The association has been found to be weaker in Caucasians whose HLA-B*5801 carriage rate is less than 6%. We examined the relationship between the different skin hypersensitivity reactions to allopurinol and the HLA-B locus in Australian patients. ⋯ Cases of AH manifesting as SJS/TENS in Australians are more likely to be in those of Asian heritage. The place of routine testing for HLA-B*5801 prior to commencing allopurinol therapy requires further investigation. However, Han Chinese origin patients commencing allopurinol might be informed of the test and may elect to have it performed as there are alternative hypouricaemic medicines, such as probenecid thereby reducing the risk of a catastrophic reaction to allopurinol.

Psychology of earthquake-induced stress cardiomyopathy, myocardial infarction and non-cardiac chest pain.
To compare psychological factors in patients presenting to hospital with earthquake-induced stress cardiomyopathy, myocardial infarction (MI) and non-cardiac chest pain. We hypothesised that patients with stress cardiomyopathy and non-cardiac chest pain would be more psychologically vulnerable than those with MI. ⋯ Our hypothesis was incorrect. Women with non-cardiac chest pain following an earthquake have higher anxiety and neuroticism scores than women with either MI or stress cardiomyopathy. Stress cardiomyopathy following an earthquake is not specific to psychologically vulnerable women. The psychology of natural disaster-induced stress cardiomyopathy may differ from that of sporadic cases.

This study aimed to assess the degree of patient compliance with medications prescribed at hospital discharge following ischaemic stroke, and concordance between self-reported medication use and general practitioner (GP) records. ⋯ Adherence to secondary stroke prevention medication was between 87% and 100% at 6 weeks with similar findings at 6 months after discharge. We speculate that these high compliance rates may be due to one-on-one stroke nurse counselling and the use of stroke information packs, which include information about the importance of adherence to secondary prevention medication.
