Parkinson disease (PD) is a complex neurodegenerative disorder that can present heterogeneously with a combination of motor and non-motor symptoms. α-synuclein, a neuronal protein, can undergo aberrant conformational change resulting in the intra-neuronal accumulation of toxic oligomers that form Lewy bodies, the pathological hallmark of PD. There is evidence that pathological α-synuclein exhibits prion-like behaviour in its mode of transmission through the nervous system. The choice of initial dopaminergic treatments should be individually tailored but long term outcomes appear to be equivalent. ⋯ Stem cell transplantation as currently being trialled is predominantly a symptomatic therapy targeting only limited regions of the brain affected by PD, and will need to be proven to be not only as effective but as safe as currently available device-assisted therapies. New modes of treatment including active immunisation against oligomeric α-synuclein and drugs that alter cellular metabolism show some promise. The inability to effectively treat a range of non-motor, non-dopaminergic symptoms remains a major therapeutic challenge.

To assess the numbers of paracetamol overdose-related hospital admissions and deaths in Australia since 2007-08, and the overdose size of intentional paracetamol overdoses since 2004. ⋯ The frequency of paracetamol overdose-related hospital admissions has increased in Australia since 2004, and the rise is associated with greater numbers of liver injury diagnoses. Overdose size and the proportion of overdoses involving modified release paracetamol have each also increased.

Multiple sclerosis is more prevalent in women of childbearing age than in any other group. As a result, the impact of multiple sclerosis and its treatment on fertility, planned and unplanned pregnancies, post partum care and breastfeeding presents unique challenges that need to be addressed in everyday clinical practice. ⋯ International pregnancy registries are essential in developing better evidence-based practice guidelines, and neurologists should be encouraged to contribute to these when possible. The management of women with multiple sclerosis, especially when they are taking disease-modifying agents, requires careful assessment of fertility and disease characteristics as well as a multidisciplinary approach to ensure positive outcomes in both mothers and their children.
