Vertigo and dysequilibrium are a frequent cause of medical consultation. Clinical evaluation is essential. Some cases of vertigo are diagnosed clinically while others require imaging, sometimes emergently (suspected stroke). MRI is the imaging modality of choice to assess the labyrinth (labyrinthitis? labyrinthine hemorrhage?), internal auditory canal (vestibular schwannoma? other tumor?…) and brain parenchyma including all structures of the auditory pathways: vestibular nuclei, vestibulocerebellar tract, tracts involved with ocular motricity, vestibular cortex… Multiple central etiologies exist: stroke, multiple sclerosis, tumor… However, some etiologies are best depicted with CT, especially lesions of the labyrinth: cholesteatoma, trauma, suspected dehiscence of the superior semicircular canal, suspected labyrinthine fistula… Finally, imaging may be negative (Benign Paroxysmal Positional Vertigo, Meniere's disease, vestibular neuritis, migraine…), merely reducing the differential diagnosis.

The extent and timescale of climate change impacts remain uncertain, including global temperature increase, sea level rise, and more frequent and intense extreme events. Uncertainties are compounded by cascading effects. Nevertheless, decision-makers must take action.

Bacterial meningitis is an increasingly rare disease that carries significant morbidity and mortality. We describe the case of a 38-year-old male with a past medical history of pituitary macroadenoma with prior endonasal surgeries on prednisone therapy daily for resultant hypopituitarism and juvenile myoclonic epilepsy on lamotrigine daily who was transferred to an academic tertiary emergency department due to concern for developing pituitary apoplexy. At the outside emergency department, the patient presented complaining of sudden onset severe headache.

Purpose Of Review: WHO defines SCD as sudden unexpected death either within 1 h of symptom onset (witnessed) or within 24 h of having been observed alive and symptom-free (unwitnessed). Sudden cardiac arrest is a major cause of mortality worldwide, with survival to hospital discharge for hospital cardiac arrest and in-hospital cardiac arrest being only 9.3 % and 21.

: Sitosterolemia is a rare autosomal recessive disorder characterized by diverse clinical manifestations ranging from asymptomatic cases to the development of xanthomas, hypercholesterolemia, premature atherosclerosis, or even sudden death during childhood. It results from homozygous or compound heterozygous pathogenic variants in the or genes. Prompt detection and intervention are essential to managing this condition and preventing severe outcomes.

Brugada syndrome (BrS) is an inherited arrhythmogenic disorder characterized by distinct electrocardiographic patterns and an increased risk of sudden cardiac death due to ventricular arrhythmias. Effective management of BrS is essential, particularly for high-risk patients with recurrent arrhythmias. While implantable cardioverter-defibrillator (ICD) is effective in terminating life-threatening arrhythmias, it does not prevent arrhythmia onset and can lead to complications such as inappropriate shocks.
