[Recommendations for the use of neurophysiological techniques in the diagnosis of brain death from the Clinical Neurophysiology Society of the Communities of Valencia and Murcia].

In Spain organ transplantation constitutes one of the greatest challenges and teamwork of hospital centres. It is estimated that in the year 2020 Spain contributed 19% of all donors to the European Union. The confirmatory support diagnosis recommends by law some complementary techniques in certain cases, including neurophysiological techniques, especially the use of electroencephalogram and evoked potentials.

[Sequelae of peripheral facial palsy].

Introduction And Objectives: The purpose of this work is to study the functional sequelae after peripheral facial palsy (PFP) to analyze its impact and relationship with the degree of facial nerve dysfunction, from the neurophysiological point of view.

Methods: We present a retrospective study which includes a total of 150 cases of peripheral facial palsy. All patients underwent electroneurography and electromyography to see the degree of axonal damage and to evaluate the existence of signs of reinervation in the muscles explored or possible innervation errors.

Mevalonic aciduria: report of two cases.

Mevalonic aciduria is a rare disease that is a consequence of a deficiency of mevalonate kinase, an inborn error in the biosynthesis of cholesterol. Approximately 30 cases have been reported. We present our data on two siblings with mevalonic aciduria as a contribution to the recognition of this subject.
