Status Epilepticus in a Tertiary Care Hospital in Morocco: A Retrospective Analysis.

Background Status epilepticus (SE) is a common neurologic emergency with high rates of mortality and morbidity. Objective To analyze the clinical characteristics, causes, management, and outcomes of patients with SE in a tertiary care hospital in Morocco. Methods A retrospective study was conducted from January 2019 to December 2021, including all patients admitted to the medico-surgical general intensive care unit (ICU) with a diagnosis of SE.

Causal evidence for the role of the sensory visual cortex in visual short-term memory maintenance.

The role of the sensory visual cortex during visual short-term memory (VSTM) remains controversial. This controversy is possibly due to methodological issues in previous attempts to investigate the effects of transcranial magnetic stimulation (TMS) on VSTM. The aim of this study was to use TMS, while covering previous methodological deficits.

Unequal allocation of overt and covert attention in Multiple Object Tracking.

In many real-life contexts, where objects are moving around, we are often required to allocate our attention unequally between targets or regions of different importance. However, typical multiple object tracking (MOT) tasks, primarily investigate equal attention allocation as the likelihood of each target being probed is the same. In two experiments, we investigated whether participants can allocate attention unequally across regions of the visual field, using a MOT task where two regions were probed with either a high and low or with equal priority.

The influence of attentional biases on multiple working memory precision parameters for children and adults.

Working memory (WM) improves dramatically during childhood but what drives this improvement is not well understood. One influential account thus far has proposed a simple increase in storage capacity. However, recent findings have shown that multiple factors, such as differences in the ability to use attention to enhance the maintenance of internal representations, as well as changes in WM precision, also interact in influencing age-related differences in WM capacity.

Severe ARDS Complicating an Acute Intentional Cresol Poisoning.

Cresol is a phenol derivative used as a disinfectant that may cause gastrointestinal corrosive injury, central nervous system, cardiovascular disturbances, renal, and hepatic injury following intoxication. We present a case of a female patient who was admitted to the emergency department after ingesting an unknown amount of cresol; she was admitted with tachypnea, shortness of breath with low oxygen level in the blood. She did not develop hepatic or renal dysfunction.

Feature binding in short-term memory and long-term learning.

In everyday experience, we encounter visual feature combinations. Some combinations are learned to support object recognition, and some are arbitrary and rapidly changing, so are retained briefly to complete ongoing tasks before being updated or forgotten. However, the boundary conditions between temporary retention of fleeting feature combinations and learning of feature bindings are unclear.

Learning What to Attend to: From the Lab to the Classroom.

Research in adult cognitive neuroscience addresses the bidirectional relationship between attentional selection and prior knowledge gained from learning and experience. This research area is ready for integration with developmental cognitive neuroscience, in particular with educational neuroscience. We review one aspect of this research area, learning what to attend to, to propose a path of integration from highly controlled experiments based on developmental and adult cognitive theories to inform cognitive interventions for learners across the lifespan.

Towards an integrative model of visual short-term memory maintenance: Evidence from the effects of attentional control, load, decay, and their interactions in childhood.

Over the past decades there has been a surge of research aiming to shed light on the nature of capacity limits to visual short-term memory (VSTM). However, an integrative account of this evidence is currently missing. We argue that investigating parameters constraining VSTM in childhood suggests a novel integrative model of VSTM maintenance, and that this in turn informs mechanisms of VSTM maintenance in adulthood.

Kounis syndrome associated with amoxicillin/clavulanic acid.

Kounis syndrome (KS) is a life-threatening medical condition that causes severes allergic reaction and acute coronary syndrome (ACS). We describe the case of 56-year-old woman who developed ACS following an anaphylactic reaction to amoxicillin/clavulanic acid. Immediately after the administration of amoxicillin/clavulanic acid, she presented a chest pain, cutaneous allergic, hypotension, and ST depression on the electrocardiogram.

[Mount Fuji sign in postoperative period after surgery for ependymoma of the third ventricle (V3): case report and review of the literature].

Mount Fuji sign also known as compressive pneumocephalus is a redoubtable postoperative neurosurgical complication. We report the clinical case of a 10 months-old patient, hospitalized in reanimation for postoperative management following surgery for ependymoma of the third ventricle. The evolution was marked by the occurrence of early postoperative compressive pneumocephalus, responsible for neurological and hemodynamic worsening.

[Retroperitoneal hematoma revealing a tumor of the inferior vena cava: about a case].

Tumors of the inferior vena cava are rare, their most common histology is represented by leiomyosarcoma. They have few specific clinical features, however, the literature does not report hemorrhagic manifestations. Preoperative diagnosis is based on tomodensitometry and magnetic resonance imaging (MRI); it is confirmed by histology.

Modeling the Effects of Perceptual Load: Saliency, Competitive Interactions, and Top-Down Biases.

A computational model of visual selective attention has been implemented to account for experimental findings on the Perceptual Load Theory (PLT) of attention. The model was designed based on existing neurophysiological findings on attentional processes with the objective to offer an explicit and biologically plausible formulation of PLT. Simulation results verified that the proposed model is capable of capturing the basic pattern of results that support the PLT as well as findings that are considered contradictory to the theory.

ERP markers of target selection discriminate children with high vs. low working memory capacity.

Selective attention enables enhancing a subset out of multiple competing items to maximize the capacity of our limited visual working memory (VWM) system. Multiple behavioral and electrophysiological studies have revealed the cognitive and neural mechanisms supporting adults' selective attention of visual percepts for encoding in VWM. However, research on children is more limited.

The interplay of spatial attentional biases and mental codes in VSTM: Developmentally informed hypotheses.

What cognitive processes influence how well we maintain information in visual short-term memory (VSTM)? We used a developmentally informed design to delve into the interplay of top-down spatial biases with the nature of the internal memory codes, motivated by documented changes for both factors over childhood. Seven-year-olds, 11-year-olds, and adults completed a VSTM task in which they decided whether a probe item had been present in a preceding memory array. Spatial cues guided participants' attention to the likely location of the to-be-probed item during maintenance.

Memory load modulates graded changes in distracter filtering.

Our ability to maintain small amounts of information in mind is critical for successful performance on a wide range of tasks. However, it remains unclear exactly how this maintenance is achieved. One possibility is that it is brought about using mechanisms that overlap with those used for attentional control.
