Background: Medical educators seek innovative ways to engage learners efficiently and effectively. Gamification has been explored as one way to accomplish this feat; however, questions remain about which contexts gamification would be most useful. Time constraints and student interest present major barriers for teaching laboratory medicine to students.

Article Synopsis
  • Medical students often see unprofessional behavior but don't know how to deal with it because their training doesn't help them practice communication skills
  • A new simulation program was created to teach students about professionalism, communication tools, and how to handle safety lapses in patient care
  • Even though students felt more knowledgeable and empowered after the program, very few actually used the skills to address unprofessional behavior when they saw it later

Dysautonomias are a heterogenous group of disorders that can cause variable symptoms ranging from isolated impairment of one autonomic function to multisystem failure. The causes are also diverse and can be central or peripheral and primary (owing to an intrinsic neurologic cause) or secondary (owing to a disorder that secondarily causes damage to the autonomic nervous system). This review covers common phenotypes of dysautonomias, primary and secondary causes, initial clinical workups, interpretation of common autonomic tests, and first-line treatments.

Chronic migraine is a neurologic disorder associated with considerable disability, lost productivity, and a profound economic burden worldwide. The past five years have seen a dramatic expansion in new treatments for this often challenging condition, among them calcitonin gene related peptide antagonists and neuromodulatory devices. This review outlines the epidemiology of and diagnostic criteria and risk factors for chronic migraine.

Telemedicine is now an established mode of clinical care for most medical specialties, and clinical teachers must teach and precept learners in this modality. However, faculty need training on how best to teach students when caring for patients via telemedicine. Effectively incorporating learners into telemedicine visits to optimize their education is a critical skill for clinical teachers.

Migraine-type photophobia, most commonly described as exacerbation of headache by light, affects nearly 90% of the patients. It is the most bothersome symptom accompanying an attack. Using subjective psychophysical assessments, we showed that migraine patients are more sensitive to all colors of light during ictal than during interictal phase and that control subjects do not experience pain when exposed to different colors of light.

Aversion to light is common among migraineurs undergoing acute attacks. Using psychophysical assessments in patients with episodic migraine, we reported that white, blue, amber, and red lights exacerbate migraine headache in a significantly larger percentage of patients and to a greater extent compared with green light. This study aimed at determining whether these findings are phase-dependent-namely, manifested exclusively during migraine (ictally) but not in its absence (interictally), or condition-dependent-ie, expressed uniquely in migraineurs but not in healthy controls.

Migraine headache is uniquely exacerbated by light. Using psychophysical assessments in patients with normal eyesight we found that green light exacerbates migraine headache significantly less than white, blue, amber or red lights. To delineate mechanisms, we used electroretinography and visual evoked potential recording in patients, and multi-unit recording of dura- and light-sensitive thalamic neurons in rats to show that green activates cone-driven retinal pathways to a lesser extent than white, blue and red; that thalamic neurons are most responsive to blue and least responsive to green; and that cortical responses to green are significantly smaller than those generated by blue, amber and red lights.

Painful neuropathy is a common and often progressive complication of diabetes. Patients frequently report symptoms of tingling, burning, lancinating pain, hyperesthesia and allodynia. The natural history of the disease may vary from intermittent mild symptoms to severe chronic daily pain; the latter is often associated with diminished quality of life.

The pace of discovery in biochemistry and genetics and its effect on clinical medicine places new curricular challenges in medical school education. We sought to evaluate students' understanding of neurogenetics and its clinical applications to design a pilot curriculum into the clinical neurology clerkship. We utilized a needs assessment and a written examination to evaluate the genetics knowledge of 81 third- and fourth-year medical students.

Small-fiber neuropathy manifests in a variety of different diseases and often results in symptoms of burning pain, shooting pain, allodynia, and hyperesthesia. Diagnosis of small-fiber neuropathy is determined primarily by the history and physical exam, but functional neurophysiologic testing and skin biopsy evaluation of intraepidermal nerve-fiber density can provide diagnostic confirmation. Management of small-fiber neuropathy depends on the underlying etiology with concurrent treatment of associated neuropathic pain.

The authors examined whether patients with schizophrenia learned sequential patterns in a probabilistic serial response time task in which pattern trials alternated with random ones. Patients showed faster and more accurate responses to pattern trials than to random trials, but controls showed greater sensitivity to patterns. The highest level of regularity learned in both groups was information about runs of 3 events.
