Abdominal migraine.

BACKGROUND: Abdominal migraine (AM) is a syndrome usually recognised in childhood. The syndrome is characterised by episodic attacks of severe abdominal pain and vasomotor symptoms, nausea and vomiting. It is a poorly understood disorder largely due to a limited recognition of this condition by the medical community. However, the publication of AM diagnostic guidelines by the International Headache Society a decade ago and the recognition of AM in the Rome Classification of functional gastrointestinal disorders have helped to legitimise this disorder and facilitate research. OVERVIEW: AM is relatively common, affecting up to 4% of the paediatric population. Whilst AM is not believed to continue into adulthood for the majority of children, it has the propensity to develop into probable migraine and recurrent abdominal pain in adulthood. The pathophysiology of this condition remains unclear and as a result treatment for this condition is suboptimal with avoidance of triggers and prophylactic treatment currently recommended when an episode begins. CONCLUSION: The recognition of AM by the IHS and the Rome Foundation should help facilitate future research into the pathophysiology of this debilitating condition and as a result better treatments for AM should emerge. Randomised controlled trials should be a priority.

Women and functional dyspepsia.

Functional dyspepsia is relatively common yet poorly understood. The best accepted diagnostic criteria are the Rome III criteria. The epidemiology, healthcare seeking rates, impact and pathophysiology are reviewed with a focus on women. Treatment is limited with no clearly established regimen currently recommended. Duodenal eosinophilia may be found in a subset. Proton pump inhibitors and prokinetic agents represent the standard therapeutic regimen after Helicobacter pylori infection has been eliminated. Some novel agents such as the prokinetic acotiamide appear promising; however, the need for a safe and efficacious treatment remains largely unmet. This review also describes the currently available management options for functional dyspepsia.

Thyroid antibodies, autoimmunity and cognitive decline: is there a population-based link?

BACKGROUND: Autoimmunity is considered an uncommon but under-recognised cause of cognitive decline. METHODS: Serum samples from 3,253 randomly selected subjects enrolled in the Hunter Community Study, aged 55-85 years, were assayed for thyrotropin stimulatory hormone, anti-thyroid peroxidase antibodies (TPO-Ab), anti-nuclear antibodies (ANA) and extractable nuclear antigens (ENA). Cognitive function was assessed using the Audio Recorded Cognitive Screen (ARCS) tool. RESULTS: TPO-Ab were found in 8.4% and ANA in 27.9% of the study population, of whom 3% had positive ENA findings. No relationship was found between the ARCS score and either TPO-Ab (coefficient = 0.133; 95% CI -0.20, 0.82, p = 0.616), ANA at a low (coefficient = 1.01; 95% CI -2.58, 0.55, p = 0.203) or a high titre (coefficient = -0.65; 95% CI -2.59, 1.28, p = 0.508), or ENA antibodies (coefficient = 5.12; 95% CI -0.53, 10.77; p = 0.076). CONCLUSIONS: Autoantibody findings are common in an aging population and are not associated with cognitive decline.

Unusual presentation of a common problem.

We report on an elderly lady with a large hiatus hernia presenting with presyncope and syncope associated with large meals. Though left atrial filling and mitral inflow was unimpaired, this case is interesting since the symptoms resolved with adjustment to meal size.
