The path from trigeminal asymmetry to cognitive impairment: a behavioral and molecular study.

Sci Rep 2021 Feb 26;11(1):4744. Epub 2021 Feb 26.

Department of Translational Research and of New Surgical and Medical Technologies, University of Pisa, Via San Zeno 31, 56127, Pisa, Italy.

Trigeminal input exerts acute and chronic effects on the brain, modulating cognitive functions. Here, new data from humans and animals suggest that these effects are caused by trigeminal influences on the Locus Coeruleus (LC). In humans subjects clenching with masseter asymmetric activity, occlusal correction improved cognition, alongside with reductions in pupil size and anisocoria, proxies of LC activity and asymmetry, respectively.

Cesk Slov Oftalmol 2020 ;76(5):232-235

The aim of the work is to approach the examination of the pupil with a focus on anisocoria, its characteristics and approach to the diagnosis of pupillotonia and Adie's syndrome and its clinical evaluation. Pupil function is important not only in neurophthalmological examination but also in general ophthalmological examination. First of all, we need to know how the reflex arc works in order to be able to exclude or confirm whether the parasympathetic or sympathetic is affected. Read More

Is using intracerebral hemorrhage scoring systems valid for mortality prediction in surgically treated patients?

Neurosurg Rev 2021 Jan 7. Epub 2021 Jan 7.

Department of Neurosurgery, Kyorin University Hospital, Tokyo, Japan.

While intracerebral hemorrhage (ICH) scoring systems provide mortality and morbidity prediction, the actual mortality rates seem to be lower than those predicted by scoring systems in our clinical impression. To assess the validity of the ICH score and the Surgical Swedish ICH (SwICH) score, we retrospectively reviewed surgically treated ICH patients between 2012 and 2019. Uni- and multivariate analyses were performed to identify variables in predicting 30-day mortality. Read More

Congenital Horner and Scimitar syndrome in a newborn: a previously unreported combination.

BMJ Case Rep 2020 Nov 30;13(11). Epub 2020 Nov 30.

Paediatrics, Unidade Local de Saude de Matosinhos EPE, Senhora da Hora, Portugal.

Here we report a case of a term newborn presenting with left palpebral ptosis, anisocoria and heterochromia as well as cleft palate and heart murmur. Congenital Horner syndrome was suspected and a thoracoabdominal CT scan was performed to rule out neuroblastoma. This revealed an anomalous drainage of right pulmonary veins to a collector that drains to the inferior vena cava, leading to the diagnosis of Scimitar syndrome. Read More

Anatomical-based percutaneous left stellate ganglion block in patients with drug-refractory electrical storm and structural heart disease: a single-centre case series.

Europace 2021 Apr;23(4):581-586

Cardiac Intensive Care Unit, Arrhythmia and Electrophysiology and Experimental Cardiology, Fondazione IRCCS Policlinico San Matteo, 27100 Pavia, Italy.

Aims: The adoption of percutaneous stellate ganglion blockade for the treatment of drug-refractory electrical storm (ES) has been increasingly reported; however, the time of onset of the anti-arrhythmic effects, the safety of a purely anatomical approach in conscious patients and the additional benefit of repeated procedures remain unclear.

Methods And Results: This study included consecutive patients undergoing percutaneous left stellate ganglion blockade (PLSGB) in our centre for drug-refractory ES. Lidocaine, bupivacaine, or a combination of both were injected in the vicinity of the left stellate ganglion. Read More

Department of Translational Research on New Technologies in Medicine and Surgery, University of Pisa, Pisa, Italy. Electronic address:

It has been observed that, in patients affected by temporomandibular disorders (TMDs) and edentulism, a left-right asymmetry in electromyographic (EMG) activity of masseter muscles during clenching and in pupil size at rest (anisocoria) is present. Both are greatly reduced by an orthotic-prosthetic correction. In parallel, the correction significantly improves cognitive performance. Read More
