Case Reports Comparative Study
Establishing a diagnosis of benign paroxysmal positional vertigo through the dix-hallpike and side-lying maneuvers: a critically appraised topic.
Many patients consult neurologists because of vertigo. Benign paroxysmal positional vertigo (BBPV) is one of the most common types of vertigo. Although the clinical presentation of this common condition is straightforward, the diagnosis and diagnostic maneuvers can be challenging. ⋯ The Dix-Hallpike test is the standard from which the diagnosis of posterior semicircular canal BPPV is made. Hence evaluations of its diagnostic test properties and utility are challenging. For patients unable to move into the Dix-Hallpike test positions, alternative tests such as the side-lying test can be attempted. These modifications, however, are rarely necessary.

Neuroendocrine hormonal conditions in epilepsy: relationship to reproductive and sexual functions.
Hormones may influence susceptibility to develop seizures. The concept of the interrelation between epilepsy, hormones, and hormonotherapy is currently emerging. On the other hand, epilepsy and its medications are associated with hormonal disturbances resulting in altered endocrine reproduction and sexual functions. ⋯ Epileptic patients will benefit from regular monitoring of ovarian and testicular functions. Early characterization of reproductive abnormalities encountered in patients with epilepsy will allow neurologists to properly choose and change antiepileptic medications. This will also improve patients' sexual function.

An isolated prolonged episode of transient amnesia can be a major manifestation of transient global amnesia (TGA) and transient epileptic amnesia (TEA). We report a case of transient amnesia associated with a left temporal tumor and try to elucidate the possible mechanism of the amnesia. ⋯ This case serves to emphasize that transient dense anterograde amnesia resembling TGA might possibly occur as a manifestation of TEA and that there is a risk of subsequent epileptic features. The amnesia in this case also supports the hypothesis of spreading depression in patients with TGA and migraine and could support the epileptic hypothesis for the pathogenesis of TGA.
