Flecainide is a class Ic anti-arrhythmic that demonstrates use dependence, meaning the medication has an increased effect on the myocardium at high heart rates. Flecainide toxicity can be identified by wide QRS complexes on an electrocardiogram (ECG). We discuss a case of a 75-year-old patient with a pacemaker who presented with concern for flecainide toxicity.

Phenomenon: While technology is useful and encouraged in medical school, the effect of media multitasking on academic performance remains concerning. Past research has investigated performance and cognitions associated with college students' in-class media multitasking behavior, but the extent and correlates among medical students is relatively unknown.

Approach: We surveyed medical students at our institution to quantify media multitasking behaviors and related beliefs, and we collected corresponding course grades.

Introduction: Klippel-Feil syndrome (KFS) is a congenital anomaly resulting from fusion of cervical vertebral bodies secondary to the dysregulation of signaling pathways during somite development. It is commonly associated with scoliosis and Sprengel deformity. We present a case of KFS with commonly associated abnormalities as well as deformities that have not yet been reported in the literature.

Retinal detachment with subsequent silicone oil retinopexy is not uncommon. A known complication of silicone retinopexy is intraventricular migration of the intraocular silicone oil. While the oil itself does not result in direct pathology, misdiagnosis may lead to an unnecessary diagnostic workup and possibly predispose the patient to surgery intervention.

Diverticulitis is a common ailment that is prevalent in the developed world. As such, the management of diverticulitis places a substantial economic burden on healthcare. Research is ongoing to further elucidate both the pathogenesis of the disease, as well as ways to reduce associated expenditures.

Moyamoya syndrome is a rare cerebrovasculopathy of unknown etiology which is associated with multiple risk factors. Moyamoya was first discovered in Japan and is reported to have an increased prevalence in the Japanese population. The term "Moyamoya" translates into "puff of smoke" and is named after the finding of the collateral cerebral vasculature that develops secondary to occlusion of an internal carotid artery at the entrance into the circle of Willis.

Dermoid cysts are rare masses of the oral cavity derived from ectodermal elements. These are benign, slow-growing tumors that are typically asymptomatic but cause complications of inflammation or dysphagia, dystonia, and airway encroachment due to mass effects. We report the case of a 17 year old female with a painless mass in the left side of the oral cavity.

The purpose of this study was to investigate the potential therapeutic qualities of Δ9-tetrahydrocannabinol (THC) with respect to slowing or halting the hallmark characteristics of Alzheimer's disease. N2a-variant amyloid-β protein precursor (AβPP) cells were incubated with THC and assayed for amyloid-β (Aβ) levels at the 6-, 24-, and 48-hour time marks. THC was also tested for synergy with caffeine, in respect to the reduction of the Aβ level in N2a/AβPPswe cells.

Previously, our lab was the first to report the use of antigen-sensitized dendritic cells as a vaccine against Alzheimer's disease (AD). In preparation of this vaccine, we sensitized the isolated dendritic cells ex vivo with Aβ peptide, and administered these sensitized dendritic cells as a therapeutic agent. This form of cell therapy has had success in preventing and/or slowing the rate of cognitive decline when administered prior to the appearance of Aβ plaques in PDAPP mice, but has not been tested in 2 × Tg models.
