Eloquent area located tumor #awakesurgery, Iceland

by Iceland "Neurophysiology Plus" Informal Grup

Reykjavík, December 2016

On 1st of December 2016, a patient with left frontal lobe space-occupying lesion was operated with awake surgery in Iceland.
A team coordinated by Ingvar Ólafsson performed preoperative neuropshychological tests and intraoperative direct brain cortical stimulation in awake patient to localize motor speech area with the aim to avoid possible neurological injuries during the procedure. The patient collaborated very well and the removal of the tumor was performed always with the patient in awakefullness performing speech mapping and several specific cognitive tests (here).

Isocinetic exercise versus isometric exercise and Cutaneous Silent Period

by Ovidiu C. Banea

Reykjavik, 18 July 2016

During summer 2016, members from Neurophysiology Unit Landspitali University Hospital, Fossvogur, Iceland (Neurology Department) are conducting an experiment using novel technique of Cutaneous Silent Period (CuSP) at baseline conditions and after two type of interventions (isocinetic and isometric exercise) in upper limb nerve-muscle "reflex" as following: median nerve - abductor pollicis brevis and ulnaris nerve - first interosseous. The aim of this work is to analyse the contribution of sensory inputs to the cutaneous silent period and if there are changes after isometric exercise suggesting involvement of other afferent fibers (beside of small mielinated A-delta) to the CuSP onset, like those of muscle spindles.

Intrathecal vs Epidural

Intrathecal use of baclofen pump affects duration of Cortical Silent Period in patients with sever spasticity. Baclofen does not affect the cutaneous SP, but prolongs the cortical SP Stetkarova I and M Kofler, 2013 (here).
To better understanding of intrathecal versus epidural administration we use the image below.

Psychogenic Movement Disorders, Neural Networks

 (2013) AR MEHTA et al Imaging Psychogenic Movement Disorders Curr Neurol Neurosci Rep open access at Springerlink.com
"Possible neural networks involved in psychogenic movement disorders based on the latest advances from the neuroimaging literature.
There is an overly sensitive emotional network, possibly conditioned by previous learning experiences, that feeds into the extended motor network via the striatum. In the presence of abnormal self-directed attention, mediated by abnormal prefrontal cortical activation that is functionally disconnected from the core motor network, these changes drive the production of aberrant movements that are not yoked to a normal sense of self-agency. This is because of hypoactivity of the supplementary motor area that normally provides the ‘corollary discharge’ signal that informs the temporoparietal junction (TPJ) ‘comparator’ what to expect in terms of sensory feedback as a result of internally generated, as opposed to externally generated, movements. 
As a consequence of the abnormal network activity, the movements are interpreted by patients as being involuntary." (Mehta et al, 2013)



The Clinical Neurophysiology of Psychogenic Movement Disorders will be discussed during the 4th Session of the Journal Club, Second Edition on 17th of February 2014.

Robotic Stereotaxic Surgery in Del Mar Hospital, Barcelona

On 21 January 2013  Medtech announced First Surgical Assisted ROBOTIC in Spain surgery using ROSA™ This landmark surgical intervention was performed by Dr. CONESA and his team at the Del Mar Hospital in Barcelona, Spain. ROSA™ was used for the pre-operative surgical planning and intra-operative positioning of sEEG deep brain electrodes used in the treatment of Epilepsy.

On 11 June 2013 Dr. Rodrigo Rocamora, Head of Epilepsy Multidisciplinary Unit, Neurology Department announced that until the date 6 epileptic patients benefited by ROSA Assisted Robotic Surgery in Del Mar Hospital Barcelona. An interview was obtained by Mr Juanjo Pardo of  rTVE program "Para Todos La 2" (here)

Prof. Dr. Vahe E. AMASSIAN


Dr. Vahe E. AMASSIAN, world recognized neuroscientist, who made extraordinary achievements in research, teaching and mentoring of graduate students, medical students and biomedical faculty died on January 7, 2013 at age 88. It began by using animal models and progressed in the last three decades to studies on humans using noninvasive trans-cranial magnetic stimulation. Vahe's hallmark was his unwavering scientific honesty. His research on the electrophysiological properties of sensory-motor systems in the brain was passionately sustained for more than 60 years (here).

Here, in Palau de Congressos de Catalunya, our Resident Physicians' Tutor, met our major colleagues who finished Clinical Neurophysiology in Hospital del Mar during 2008-2011 period: Monica Vicente, Nadim Ailouti Caballero, Salvador Amezcua and Jacob Diaz.
Few days ago, Dra Inma Royo de Mingo and Dr Salvador Amezcua



We had the opportunity to talk with them and to open new contacts for this Clinical Neurophysiology Journal Club WEBSITE. Salva, CN Specialist in a Hospital of the lovely Balearic Island of Menorca had the idea to open a new section in our blog to present a monthly interesting case report.

Excessive daytime sleepiness (EDS), Epworth 21/24 of 5 year associated to Paraneoplastic Encephalitis in a 40 year old pacient with orchiectomy for testicular teratoma and drug Resistant Epilepsy, case report in poster presented with 129H/2225 code by Dr Ion Alvarez Guerrico, clinical neurophysiologist of our CN Staff in Hospital del Mar.
In 2004 a comprehensive clinical analysis of 38 patients with anti-Ma2 encephalitis was performed by  Dalmau et al and was published in Brain (see here). Overall, 12 patients had clinical evidence of seizures (seven partial complex seizures; five partial complex seizures and generalized tonicclonic seizures). Thirteen patients developed diencephalic dysfunction, 12 with EDS and two of them with cataplexy and hypnagogic hallucinations.
The case presented show the presence of both limbic and diencephalic symptoms with manifestation during a large period of time and the importance of the Clinical Neurophysiology to evidence the clinical manifestations of these injuries wich appear together or before of cancer complications.
