A 5-year follow up of patients discharged with non-specific abdominal pain: out of sight, out of mind?
Acute non-specific abdominal pain (NSAP) is prevalent in 6-25% of the general population and is a common cause of admission to the emergency department (ED). Despite involvement of substantial financial and human resources, there are few data on long-term outcome after initial diagnosis. The aim of this study was to evaluate long-term outcome of patients initially admitted with NSAP to an ED. ⋯ The long-term impact for patients initially admitted to our ED with acute NSAP is significant--28% of patients continue to suffer from recurring NSAP after 5 years. NSAP therefore remains, despite more advanced diagnostic tools, a true and, as yet, unsolved problem.

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.

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.

The association between time to disposition plan in the emergency department and in-hospital mortality of general medical patients.
A perceived risk of time-limited emergency department (ED) assessment of patients is inadequate workup leading to inappropriate disposition. The aim of this study was to examine the association of time to disposition plan (TDP) on ED length of stay (LOS) and correlate this to mortality. ⋯ In the setting of prolonged ED LOS, completing ED assessment and management within 4 h of presentation was associated with significantly higher mortality. Further prospective studies are required to understand the relationship between rapid decision making in the ED and patient safety.

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.
