Treatment of moderate-to-severe psoriasis in adults: An expert consensus statement using a Delphi method to produce a decision-making algorithm.

Background: New highly effective drugs for moderate-to-severe cutaneous psoriasis are regularly marketed, and the hierarchy of treatments thus requires frequent review.

Objectives: A Delphi method was used to enable a structured expert consensus on the use of systemic treatments and phototherapy among adults with moderate-to-severe psoriasis.

Methods: The Delphi method consists in achieving a convergence of opinions among a panel of experts using several rounds of questionnaires with controlled feedback between rounds.

CACNA1A-associated epilepsy: Electroclinical findings and treatment response on seizures in 18 patients.

CACNA1A pathogenic mutations are involved in various neurological phenotypes including episodic ataxia (EA2), spinocerebellar ataxia (SCA6), and familial hemiplegic migraine (FHM1). Epilepsy is poorly documented. We studied 18 patients (10 males) carrying de novo or inherited CACNA1A mutations, with median age of 2,5 years at epilepsy onset.

The epileptology of GNB5 encephalopathy.

Pathogenic variants in GNB5 cause an autosomal recessive neurodevelopmental disorder with neonatal sinus bradycardia. Seizures or epilepsy occurred in 10 of 22 previously reported cases, including 6 children from one family. We delineate the epileptology of GNB5 encephalopathy.

A new phototherapy regimen during winter as an add-on therapy, coupled with oral vitamin D supplementation, for the long-term control of atopic dermatitis: study protocol for a multicentre, randomized, crossover, pragmatic trial - the PRADA trial.

Background: Atopic dermatitis is a highly prevalent, chronic, relapsing disease in both adults and children. On the severity spectrum, lower-end patients benefit from small amounts of topical anti-inflammatory treatments (TAT), whereas higher-end patients need systemic immunosuppressants; in-between patients are treated with TAT and phototherapy. The major therapeutic challenge in this population is the long-term control of disease activity, and the current TAT-based pro-active strategy does not meet all their needs.

Abnormal Interhemispheric Synchrony in Neonatal Hypoxic-Ischemic Encephalopathy: A Retrospective Pilot Study.

Background: Abnormal interhemispheric synchrony has been described in many clinical compromises in brain function, but its prognostic value in neonatal hypoxic-ischemic encephalopathy (HIE) is unknown.

Objectives: The study aimed at describing the frequency of abnormal interhemispheric synchrony in infants with HIE and to explore its prognostic value. The main outcome was survival without major disabilities.

The Indian Basket Trick: a case of delayed paraplegia with complete recovery, caused by misplaced thoracic pedicle screw.

Introduction: Pedicle screw fixation allows purchase of all three spinal columns without encroaching into the spinal canal improving fracture fixation, as well as deformity correction. Fortunately, neurologic injury associated with pedicle screw malposition is rare.

Case Presentation: A 19-year-old boy was surgically treated for severe right thoracic scoliosis associated with a Chiari Type 1 malformation and a C6 to T7 syringomyelia.

WWOX-related encephalopathies: delineation of the phenotypical spectrum and emerging genotype-phenotype correlation.

Background: Homozygous mutations in WWOX were reported in eight individuals of two families with autosomal recessive spinocerebellar ataxia type 12 and in two siblings with infantile epileptic encephalopathy (IEE), including one who deceased prior to DNA sampling.

Methods: By combining array comparative genomic hybridisation, targeted Sanger sequencing and next generation sequencing, we identified five further patients from four families with IEE due to biallelic alterations of WWOX.

Results: We identified eight deleterious WWOX alleles consisting in four deletions, a four base-pair frameshifting deletion, one missense and two nonsense mutations.

Bullous pemphigoid induced by vildagliptin: a report of three cases.

To report three cases of bullous pemphigoid in patients treated with vildagliptin. Case 1: An 86-year-old woman presented with bullous pemphigoid after 1 month of treatment with vildagliptin and metformin. After introduction of clobetasol, the symptoms resolved although vildagliptin was continued.

Visual neurophysiological dysfunction in infants exposed to hydroxychloroquine in utero.

Aim: Hydroxychloroquine therapy during pregnancy is thought to be safe for foetuses. Normal visual function has been showed on clinical grounds in infants exposed in utero to hydroxychloroquine, but there are few visual neurophysiological data. Our study was designed to assess retina and visual pathways using electroretinogram and visual evoked potentials in a series of infants born to mothers treated by hydroxychloroquine for connective tissue diseases.

Usher syndrome type 1: early detection of electroretinographic changes.

Background: Usher syndrome type 1 needs to be diagnosed at early age in order to timely manage speech therapy, cochlear implantation, and genetic counseling. Few data are available regarding electroretinographic testing before the age of six years.

Aim: To describe electroretinographic changes in young children with Usher syndrome type 1.

Early neurological phenotype in 4 children with biallelic PRODH mutations.

Hyperprolinemia type I (HPI) results from a deficiency of proline oxidase (POX), involved in the first step in the conversion of proline to glutamate. Diverse phenotypes were described in patients with HPI, prior to the identification of the POX gene (PRODH): whereas various patients were asymptomatic, others had neurological and extraneurological defects. The PRODH gene is located in the region deleted in velocardiofacial syndrome (VCFS).

Hemispheric asymmetry in cortical control of memory-guided saccades. A transcranial magnetic stimulation study.

To study the temporal organisation of memory-guided saccade control we used single-pulse transcranial magnetic stimulation (TMS) over the left posterior parietal (PPC) and prefrontal cortex (PFC) in eight healthy subjects. TMS was applied either following presentation of a visual target, i.e.

Improvement of memory guided saccades in parkinsonian patients by high frequency subthalamic nucleus stimulation.

Recent studies in the monkey suggest that the subthalamic nucleus (STN) is involved in control of eye movement, yet its functional significance in humans is unknown. Saccadic eye movements were studied in eight parkinsonian patients treated by bilateral electrical stimulation of the STN. STN stimulation improved the accuracy of memory guided saccades but not of reflexive visually guided saccades and had no effect on the antisaccade task.

Memory guided saccade deficit after caudate nucleus lesion.

The role of the caudate nucleus in ocular motor control is not well determined in humans. Eye movements were recorded from a 45 year old man with infarctions involving bilaterally the body of the caudate nucleus, with a greater extent on the left side. The patient exhibited a pattern of eye movement abnormalities in which a delay dependent decrease of accuracy of memory guided saccades predominated.

Role of the prefrontal cortex in the control of express saccades. A transcranial magnetic stimulation study.

Single pulse transcranial magnet stimulation (TMS) was applied in five subjects during a saccadic gap task, i.e. with a temporal gap of 200 ms between the extinguishing of the central fixation point and the appearance of the lateral target.

Cortical control of saccades.

Saccadic eye movements are controlled by a cortical network composed of several oculomotor areas that are now accurately localized. Clinical and experimental studies have enabled us to understand their specific roles better. These areas are: (1) the parietal eye field (PEF) located in the intraparietal sulcus involved in visuospatial integration and in reflexive saccade triggering; (2) the frontal eye field (FEF), located in the precentral gyrus, involved in the preparation and the triggering of purposive saccades; and (3) the supplementary eye field (SEF) on the medial wall of the frontal lobe, probably involved in the temporal control of sequences of visually guided saccades and in eye-hand coordination.

Effects of single-pulse transcranial magnetic stimulation over the prefrontal and posterior parietal cortices during memory-guided saccades in humans.

1. We used single-pulse transcranial magnetic stimulation (TMS) to explore the temporal organization of the cortical control of memory-guided saccades in eight humans. The posterior parietal cortex (PPC) or the dorsolateral prefrontal cortex (DPFC), which are both known to be involved in the control of such saccades, were stimulated on the right side at different time intervals after the presentation of a flashed lateral visual target.

Saccade disturbances after bilateral lentiform nucleus lesions in humans.

Objective: To determine the roles of the putamen and pallidum in ocular motor control.

Methods: Eye movements were recorded electro-oculographically in nine patients with bilateral focal lesions affecting the lentiform nucleus, and in 12 age matched control subjects. Reflexive visually guided saccades (gap task), antisaccades, memorised sequences of saccades, memory guided saccades (with visual input only, and with both visual and vestibular inputs), and predictive saccades (with and without gap) were studied.

A study of two procedures of HIV-1 isolation from whole blood cultures.

Culture techniques for isolation of HIV-1 from small amounts of whole blood (WB) treated with anticoagulant have been reported and gave results identical to those of culture of separated peripheral blood mononuclear cells. Some authors obtained much higher isolation rates when EDTA was used instead of heparin. We compared two previously described techniques for cultivation of HIV-1 from WB of adult HIV+ patients staged according to the CDC classification.

Cortical control of saccades.

A scheme for the cortical control of saccadic eye movements is proposed based partly on defects revealed by specific test paradigms in humans with discrete lesions. Three different cortical areas are capable of triggering saccades. The frontal eye field disengages fixation, and triggers intentional saccades to visible targets, to remembered target locations, or to the location where it is predicted that the target will reappear (i.
