Optimal differentiated thyroid cancer management in the elderly.

The incidence of differentiated thyroid cancer is increasing worldwide across all age groups. While most patients with differentiated thyroid cancer have a good prognosis, aggressive disease is more common in the elderly and disease-specific mortality is higher. Treatment options for differentiated thyroid cancer include surgery, levothyroxine, radioactive iodine, external beam radiotherapy and kinase inhibitors. Rational and evidence-based management is particularly important in older individuals because they may experience greater toxicities from the therapeutic options. We advocate an explicit risk-benefit analytic approach to thyroid cancer care that emphasises individual patient factors, likely disease biology and progression, and age-dependent treatment characteristics to ensure optimal treatment. In particular, this risk-benefit approach should seek to identify patients with aggressive disease, and, within a multidisciplinary setting, balance the likelihood of treatment success with the probability of treatment-related adverse effects.

Lower treatment targets for gestational diabetes: is lower really better?

Proposed lower diagnostic thresholds and lower treatment targets for gestational diabetes have been controversial internationally. Intervention trials for the recently revised lower Australian treatment targets are currently lacking. While there may be benefits, lowering treatment targets may cause a number of harms including increased risk of hypoglycaemia in pregnant women, greater medicolegal risk for health practitioners, and heavier economic costs for the health system. Regional and remote care providers in particular will have greater costs, and may be overwhelmed in attempts to implement new treatment targets. An excessively glucose-centric focus may divert attention and resources from identifying and addressing other important and growing contributors to adverse pregnancy outcomes, such as obesity. Important groups such as Aboriginal and Torres Strait Islander Australians may not gain overall benefit from lowering treatment targets for gestational diabetes because of current low birthweights and the effect of social costs. It has not yet been established whether implementing lower treatment targets for gestational diabetes will create more benefit than harm. Implementation at this stage is premature.

Safer hours for doctors and improved safety for patients.

An increasing weight of evidence is demonstrating that sleep deprivation and circadian rhythm disruption in doctors are associated with human error and harm to both patients and doctors. The increasing junior doctor workforce entering the hospital system in Australia provides a rare opportunity for workplace and roster reforms. There are cultural, educational and industrial challenges to reforming working hours. Any changes should be evidence-based and monitored to ensure that training for junior doctors and patient care are not compromised.

Emerging inequality and potential unconstitutionality - the case for reform of the intern priority system.

Internship selection is becoming more competitive due to substantial increases in numbers of medical graduates. Australian states operate a "priority system" for medical internship selection which discriminates against Australian interstate applicants. This discrimination arguably infringes section 117 of the Australian Constitution, which seeks to ensure that all citizens are treated equally and promotes national unity. The priority system should be reformed. It is inequitable and inconsistent with other aspects of medical training and regulation.

Chronic urticaria following acute hepatitis A.

Urticaria has a documented association with the prodromal phases of hepatitis A, B and, although still contentious, likely hepatitis C. Despite the documented association there are few actual reported cases of urticaria occurring with hepatitis A infection and in all of the cases reported so far the urticaria preceded the diagnosis of hepatitis A and was acute rather than chronic. We describe a case of urticaria occurring following acute infection with hepatitis A, which persisted beyond 6 weeks and therefore was by definition chronic. Although chronic urticaria has been reported to be associated with other forms of viral hepatitis, to the best of our knowledge this has not been reported previously with hepatitis A.

Conflict of interest guidelines for clinical guidelines.

• Clinical guidelines are being increasingly produced to improve quality of care, but are vulnerable to bias. • Only 15% of guidelines on the National Health and Medical Research Council portal from the most prolific developers have published conflict of interest statements, and fewer detail the processes used to manage conflicts. • Comprehensive disclosure of conflicts is needed to safeguard the integrity of clinical guidelines and the medical profession. • Peak bodies and clinicians should seek to promote an improvement to current poor practice.
