The Australasian Society of Clinical Immunology and Allergy, the peak professional body for clinical immunology and allergy in Australia and New Zealand, develops and provides information on a wide range of immune-mediated disorders, including advice about infant feeding and allergy prevention for health professionals and families. Guidelines for infant feeding and early onset allergy prevention were published in 2016, with additional guidance published in 2017 and 2018, based on emerging evidence.

The evidence-based national clinical practice guidelines for the management of cutaneous melanoma published in 2008 are currently being updated. This article summarises the findings from multiple chapters of the guidelines on different methods of melanoma detection and of monitoring the skin for patients at high risk of melanoma. Early detection of melanoma is critical, as thinner tumours are associated with enhanced survival; therefore, strategies to improve early detection are important to reduce melanoma-related mortality.


To identify factors associated with receiving acute goal-directed treatment, being assessed for ongoing rehabilitation, and receiving post-acute rehabilitation after having a stroke.


Criminal cases involving human immunodeficiency virus transmission or exposure require that courts correctly comprehend the rapidly evolving science of HIV transmission and the impact of an HIV diagnosis. This consensus statement, written by leading HIV clinicians and scientists, provides current scientific evidence to facilitate just outcomes in Australian criminal cases involving HIV.Main recommendations: Caution should be exercised when considering charges or prosecutions regarding HIV transmission or exposure because:Scientific evidence shows that the risk of HIV transmission during sex between partners of different HIV serostatus can be low, negligible or too low to quantify, even when the HIV-positive partner is not taking effective antiretroviral therapy, depending on the nature of the sexual act, the viral load of the partner with HIV, and whether a condom or pre-exposure prophylaxis is employed to reduce risk.The use of phylogenetic analysis in cases of suspected HIV transmission requires careful consideration of its limited probative value as evidence of causation of HIV infection, although such an approach may provide valuable information, particularly in relation to excluding HIV transmission between individuals.Most people recently infected with HIV are able to commence simple treatment providing them a normal and healthy life expectancy, largely comparable with their HIV-negative peers. Among people who have been diagnosed and are receiving treatment, HIV is rarely life threatening. People with HIV can conceive children with negligible risk to their partner and low risk to their child.Changes in management as result of the consensus statement: Given the limited risk of HIV transmission per sexual act and the limited long term harms experienced by most people recently diagnosed with HIV, appropriate care should be taken before HIV prosecutions are pursued. Careful attention should be paid to the best scientific evidence on HIV risk and harms, with consideration given to alternatives to prosecution, including public health management.

In 2017, the National Cervical Screening Program in Australia will transition to 5-yearly primary HPV screening for all women, irrespective of human papillomavirus (HPV) vaccination status. As an adjunct to the mainstream program, HPV testing on self-collected samples will be offered under practitioner supervision to all unscreened and underscreened women aged 30-74 years. We quantified how different screening decisions affect the future risk of cervical cancer.

Older people with cognitive impairment and/or dementia may be particularly vulnerable to diminished financial decision-making capacity. Financial capacity refers to the ability to satisfactorily manage one’s financial affairs in a manner consistent with personal self-interest and values. Impairment of financial capacity makes the older individual vulnerable to financial exploitation, may negatively affect their family’s financial situation and places strain on relationships within the family. Clinicians are often on the front line of responding to queries regarding decision-making capacity, and clinical evaluation options are often not well understood. Assessment of financial capacity should include formal objective assessment in addition to a clinical interview and gathering contextual data. Development of a flexible, empirically supported and clinically relevant assessment approach that spans all dimensions of financial capacity yet is simple enough to be used by non-specialist clinicians is needed.
