The aims of this study were to describe the characteristics of and outcome of patients with chest pain in relation to transport by the emergency medical services (EMS) and to describe possible changes in this relationship in a 20-year perspective. ⋯ For 20 years, the proportion of patients with chest pain using the EMS increased. EMS users were more frequently hospitalized in 1986 to 1987 than in 2008. In overall terms, mortality was higher among EMS users than among nonusers in both periods. Among hospitalized patients with myocardial ischemia and among patients with a final diagnosis of AMI, EMS use was associated with a higher 30-day mortality only in 1986 to 1987.

Charles Bonnet syndrome describes visual field or acuity loss with complex hallucinations. This typically occurs in the elderly with preexisting visual impairment. We describe a patient who presented to the emergency department with acute hemianopsia and intermittent complex hallucinations. ⋯ Results of computed tomography and magnetic resonance imaging of the head with contrast were negative. Standard 30-minute electroencephalography revealed near-continuous epileptiform discharges in the left occipital lobe. To our knowledge, this is the first case report of new-onset seizure presenting as Charles Bonnet syndrome.

Lung cancer is one of the most common neoplasms associated with cardiac metastasis, and the pericardium is often affected. However, isolated myocardial involvement in these patients is very uncommon. ⋯ Myocardial metastasis rarely mimics an acute myocardial infarction. We report a case of a 59-year-old man with a metastatic lung cancer into the myocardium mimicking an acute myocardial infarction.

Pregabalin, a synthetic derivate of the inhibitory neurotransmitter γ-aminobutyric acid, shows antiepileptic, analgesic, anticonvulsant, anxiolytic, and sleep-modulating activities. The major advantage of pregabalin is its relative reliability, easy use, high tolerance, and lack of negative interaction with other drugs. A 65-year-old woman with medical histories of diabetes mellitus, lumbar spondylosis, diabetic nephropathy, chronic renal failure, and anemia of chronic disease was admitted with the complaint of dizziness and syncope. ⋯ To our knowledge, this is the first case of complete AV block associated with pregabalin. We believe that AV block occurred as a result of pregabalin's effect on L-type Ca++ channels in the heart. Pregabalin's different effects on electrocardiogram and on the heart in different individuals may have an association with the patterns of distribution of the L-type calcium channels in myocardium.

We report a rare case presenting with up to 50 episodes of syncopes per day in a 54-year-old man with the ultimate diagnosis of idiopathic glossopharyngeal neuralgia. All episodes were started with a severe pain sensation in the right side of the throat followed by asystole and then very slow ventricular escape beats. The patient was successfully treated with the combination of carbamazepine, gabapentin, and dual-chamber pacemaker implantation.
