BACKGROUND: Abscess co-existing within a brain tumor is a rare entity. Case reports in literature primarily consist of sellar pathology and parenchymal lesions including meningioma, glioma, and metastases. We report a case of glioblastoma with an intra-tumoral abscess in a middle-aged lady with no prior invasive procedure or systemic focus of infection. CASE DESCRIPTION: A 45-year old lady presented with new onset generalized seizures and rapidly progressive left hemiparesis...

Trepanation is one of the most ancient and applied surgical treatments; several archaeologically documented cases are known, dated back from Prehistory to the Middle ages. This case study reports the anthropological analysis of the skeletal remains of a young medieval woman and a fetus (Imola, Italy). The fetal remains were laid between her pelvis and lower limbs. A perforating injury was observed to her frontal bone. After assessing biological profiles, we attempted to interpret the injury and to reconstruct possible circumstances of death...

Frontal sinus osteoma accompanied by intracranial mucocele and local hyperostosis frontalis interna has never been reported. A 47-year-old woman presented with a 3-month history of intermittent headache. Physical examination revealed no neurological abnormality. Contrasted MRI showed a frontal heterogeneously enhanced lesion with adjacent non-enhanced cyst. Computed tomography showed a bone-density mass, which was accompanied by local hyperostosis frontalis interna, filled the left frontal sinus and extended intracranially...

OBJECTIVE: Minimally invasive alternatives to the pterional craniotomy include the minipterional and the supraorbital craniotomy (SOC). The latter is performed via either an eyebrow or an eyelid skin incision. The purpose of this systematic review was to analyze the type and the incidence of approach-related complications of these keyhole craniotomies. METHODS: We review pertinent publications retrieved by search in the PubMed/Medline database. Inclusion criteria were all full-text publications, abstracts, and posters in English, up to 2016, reporting clinical results...

This study investigated EEG activity in the upper alpha band during the well-known Picture Completion Task of the Torrance Test of Creative Thinking (TTCT), a widely used creative ideation task in the figural domain. The application of a sophisticated computerized version of the TTCT facilitating the online assessment and digitalizing of participant's drawings allowed to separate two central stages of the creative ideation process (i.e., idea generation and idea elaboration). During idea generation, the participants' task was to generate an initial draft of an original and creative completion of the presented abstract lines and figures of the TTCT...

Yue Li, Lei Zhang, Kehong Long, Hui Gong, Hao Lei
A growing body of literature has suggested that video game playing can induce functional and structural plasticity of the brain. The underlying mechanisms, however, remain poorly understood. In this study, functional near-infrared spectroscopy (fNIRS) was used to record prefrontal activities in 24 experienced game players when they played a massively multiplayer online battle arena (MOBA) video game, League of Legends (LOL), under naturalistic conditions. It was observed that game onset was associated with significant activations in the ventrolateral prefrontal cortex (VLPFC) and concomitant deactivations in the dorsolateral prefrontal cortex (DLPFC) and frontal pole area (FPA)...

OBJECTIVES: To assess [ 18 F]AV-1451 tau-PET uptake patterns across the primary progressive aphasia (PPA) variants (logopenic, semantic and agrammatic), examine regional uptake patterns of [ 18 F]AV-1451 independent of clinical diagnosis, and compare the diagnostic utility of [ 18 F]AV-1451, [ 18 F]-fluorodeoxygluclose (FDG)-PET and MRI to differentiate the PPA variants. METHODS: We performed statistical parametric mapping of [ 18 F]AV-1451 across 40 PPA patients (logopenic-PPA=14, semantic-PPA=13 and agrammatic-PPA=13) compared to 80 cognitively normal, PiB-negative controls, age and gender matched 2:1...

Adolescents' exposure to community violence is a significant public health issue in urban settings and has been associated with poorer cognitive performance and increased risk for psychiatric illnesses, including PTSD. However, no study to date has investigated the neural correlates of community violence exposure in adolescents. Sixty-five healthy adolescents (age = 14-18 years; 36 females, 29 males) from moderate- to high-crime neighborhoods in Los Angeles reported their violence exposure, parents' education level, and free/reduced school lunch status (socio-economic status, SES), and underwent structural neuroimaging and intelligence testing...

The concept of "watershed shift"(WS)has been proposed as a cause of the ischemic complications following a superficial temporal artery-middle cerebral artery(STA-MCA)bypass operation performed for the management of moyamoya disease. Previous reports have observed that only 1.2-5.7% of the patients who underwent a bypass operation for the management of moyamoya disease developed cerebral infarction secondary to the WS phenomenon. To date, the WS phenomenon has not been objectively proven on imaging studies...

BACKGROUND AND PURPOSE: Validated neuroimaging markers of HIV-associated neurocognitive disorder in patients on antiretroviral therapy are urgently needed for clinical trials. The purpose of this study was to explore the relationship between cognitive impairment and brain metabolism in older subjects with HIV infection. It was hypothesized that MR spectroscopy measurements related to neuronal health and function (particularly N -acetylaspartate and glutamate) would be lower in HIV-positive subjects with worse cognitive performance...

To investigate the change in clinical outcomes and biomechanical properties of the knee in response to upper partial fibulectomy. Sixteen patients with medial compartment knee osteoarthritis (KOA) underwent upper partial fibulectomy. Visual analog scale (VAS) pain, the hospital for special surgery knee score (HSS), hip-knee-ankle (HKA) angle (measured in the frontal plane), and flexion/extension range of motion of the knee were assessed before and up to 6 months after surgery. Patients were evaluated for gait parameters and overall peak knee adduction moment (KAM)...

Gait asymmetry and dynamic balance impairments observed in post-stroke individuals increase their risk of fall. Moreover, walking while performing a cognitive task (i.e. dual-task) disturbs the control of balance in post-stroke individuals. Here we investigated the mediolateral dynamic stability in twenty-two community-dwelling participants (12 post-strokes and 10 healthy controls) while walking in single-task (normal gait) and four different dual-tasks (cognitive-motor interference). Positions of the extrapolated center of mass and mediolateral widths of both margin of stability and base of support were extracted from 35 marker trajectories...

Insomnia Disorder (ID) is the second-most common mental disorder and has a far-reaching impact on daytime functioning. A meta-analysis indicates that, of all cognitive domains, declarative memory involving the hippocampus is most affected in insomnia. Hippocampal functioning has consistently been shown to be sensitive to experimental sleep deprivation. Insomnia however differs from sleep deprivation in many aspects, and findings on hippocampal structure and function have been equivocal. The present study used both structural and resting-state functional Magnetic Resonance Imaging in a larger sample than previously reported to evaluate hippocampal volume and functional connectivity in ID...

RATIONALE: Cardiac arrest (CA) is a serious condition characterized by high mortality rates, even after initial successful resuscitation, mainly due to neurological damage. Whether brain-heart communication is associated with outcome after CA is unknown. Heartbeat-evoked brain potentials (HEPs) represent neurophysiological indicators of brain-heart communication. The aim of this study was to address the association between HEPs and survival after CA. METHODS: HEPs were calculated from resting EEG/ECG in 55 CA patients 24 hours after resuscitation...

Paranasal sinuses are highly variable among living and fossil hominins and their function(s) are poorly understood. It has been argued they serve no particular function and are biological 'spandrels' arising as a structural consequence of changes in associated bones and/or soft tissue structures. In contrast, others have suggested that sinuses have one or more functions, in olfaction, respiration, thermoregulation, nitric oxide production, voice resonance, reduction of skull weight, and craniofacial biomechanics...
