Chronic idiopathic constipation (CIC) is one of the most common gastrointestinal disorders, with a global prevalence of 14%. It is commoner in women and its prevalence increases with age. There are three subtypes of CIC: dyssynergic defaecation, slow transit constipation and normal transit constipation, which is the most common subtype. ⋯ If patients do not respond to these simple changes, then treatment with osmotic and stimulant laxatives should be trialled. Patients not responding to traditional laxatives should be offered treatment with prosecretory agents such as lubiprostone, linaclotide and plecanatide, or the 5-HT4 receptor agonist prucalopride, where available. If there is no response to pharmacological treatment, surgical intervention can be considered, but it is only suitable for a carefully selected subset of patients with proven slow transit constipation.

Codeine dependence is a significant public health problem, motivating the recent rescheduling of codeine in Australia (1 February 2018). To provide information for informing clinical responses, we undertook a systematic review of what is known about identifying and treating codeine dependence. ⋯ Strategies for identifying problematic codeine use are needed. Identifying codeine dependence in clinical settings is often delayed, contributing to serious morbidity. Commonly described approaches for managing codeine dependence include opioid taper, opioid agonist treatment, and psychological therapies. These approaches are consistent with published evidence for pharmaceutical opioid dependence treatment and with broader frameworks for treating opioid dependence.

Lung transplantation in Australia is 32 years old in 2018. From its early infancy in 1986, it continues to evolve and is internationally recognised as demonstrating world's best practices in organ donation, utilisation and transplantation procedures. ⋯ Parallel to this, lung transplant outcomes have continued to improve. While the management of lung transplant recipients is heavily dependent on a tertiary care paradigm, this model is well developed and has been extremely successful, with Australian outcomes exceeding those of the International Society for Heart and Lung Transplantation Registry at all time points.

Parkinson disease (PD) affects people of all races and ethnicity worldwide. PD is a multineurotransmitter and multisystem disorder and our current concept of the natural history of PD has changed considerably over the past decades. ⋯ Several factors might play a role in the influence of ethnicity on PD, such as pharmacogenetics, sociocultural aspects and environmental exposures. Increased knowledge on the role of ethnicity in PD may help shed light on the symptom expression and treatment response of PD, address inequalities in health care delivery worldwide and improve the delivery of personalised medicine.

Most patients with Parkinson disease (PD) have non-motor symptoms (NMS), and on average these can range from four to 19 different symptoms. NMS dominate the prodromal phase of PD and some may serve as clinical biomarkers of PD. NMS can be dopaminergic, non-dopaminergic, of genetic origin or drug induced. ⋯ The syndromic nature of PD is underpinned by non-motor subtypes which are likely to be related to specific dysfunction of cholinergic, noradrenergic, serotonergic pathways in the brain, not just the dopaminergic pathways. NMS can be treated by dopaminergic and non-dopaminergic strategies, but further robust studies supported by evidence from animal models are required. The future of modern treatment of PD needs to be supported by the delivery of personalised medicine.
