Introduction: Acute otitis media is a common disease in children under the age of 5 years due to their primitive ear anatomy. One of its consequences is otitis media with effusion (OME), which is a condition wherein serous secretion accumulates in the middle ear due to Eustachian tube dysfunction. OME results in conductive hearing loss, impacting children's learning and development.

This graphic but relatively unknown sign helped us pinpoint the diagnosis. Our patient, a 24-year-old male migrant worker, presented with a five-month history of a racking cough with expectoration of blood-streaked sputum.

- Binge drinking can trigger atrial fibrillation (AF), but the exact reasons for this relationship are not well understood; this study aimed to explore the effects of alcohol on heart rhythm and structure using advanced imaging and monitoring techniques.* -
- Involving 50 participants, the study found that binge drinking led to an increased heart rate during consumption and a higher than baseline number of atrial ectopic beats during the hangover phase, along with a decrease in heart rate variability.* -
- Findings indicate that binge drinking causes sympathetic nervous system activation followed by a rebound parasympathetic response, leading to mechanical dysfunction in the heart's atria, which may help explain the link between binge drinking and AF episodes.*
Objective: To assess the impact of elevated heart rate (HR) on the diagnostic accuracy and image quality of second-generation 320-detector computed tomography coronary angiography (320-CTCA).
Methods: Consecutive patients with suspected coronary disease referred for invasive coronary angiography (ICA) were prospectively recruited and underwent 320-CTCA. Pre-scan beta-blockers were administered if native HR>80 bpm and post-scan cohorts stratified by traditional (HR ≤60 bpm) and elevated HR (61-80 bpm).
Background: Emergency medical services (EMS) transport to hospital is recommended in acute coronary syndrome (ACS) guidelines, but only half of patients with ACS currently use EMS. The recent Australian Warning Signs campaign conducted by the Heart Foundation addressed some of the known barriers against using EMS. Our aim was to examine the influence of awareness of the campaign on these barriers in patients with ACS.
