Evolution of Volatile Emission in Rhus coriaria Organs During Different Stages of Growth and Evaluation of the Essential Oil Composition.

Rhus coriaria, also known as Sumac, has been traditionally used in many countries as spice, condiment, dying agent, and medicinal herb. The chemical composition of essential oils (EOs) and the volatile emissions from different organs of this species collected in Sicily (Italy) were analyzed by gas chromatography-flame ionization detection and gas chromatography/mass spectrometry. Monoterpene and sesquiterpene hydrocarbons were the most abundant class in the volatile emissions with β-caryophyllene and α-pinene were the main constituents in the majority of the examined samples.

Aphasia as a rare presentation of monosymptomatic demyelinating disease: case report and review of the literature.

We present a case of sudden-onset aphasia due to a single pathological lesion, which at neuroradiological imaging studies was suggestive of glioma, while on biopsy proved be of demyelinating nature. Every cause of demyelinating lesions of the central nervous system was considered in the differential diagnosis, concluding for a primary demyelinating disease. The clinical and radiological differences between multiple sclerosis and acute disseminated encephalomyelitis are discussed.
