BACKGROUND: Fusobacterium nucleatum is a strict anaerobic microorganism commensal to the human oropharynx and gastrointestinal tract, which causes a wide spectrum of human diseases and it is an important pathogen in abscesses. CASE PRESENTATION: We report the case of a previously healthy 64-year-old woman with multiple abscesses due to Fusobacterium nucleatum, involving liver, pleura and brain. Fusobacterium was not recovered from blood cultures nor from culture of hepatic, pleural and brain drain fluid...

OBJECTIVES: The configuration of the confluence of sinuses differs not only between individuals, but also between the two brain hemispheres, making the anatomical classification of this region difficult. In this study, we evaluated the anatomy of the confluence of sinuses and ascertained the accuracy and usefulness of digital subtraction angiography (DSA) in the evaluation of cerebral veins. METHODS: Bilateral carotid and vertebral artery angiographies were performed in 500 adult patients to evaluate the anatomy of the confluence of sinuses and contributory venous sinuses...

Measurement of intracranial pressure (ICP) can be invaluable in the management of critically ill patients. Cerebrospinal fluid (CSF) is produced by the choroid plexus in the brain ventricles (a set of communicating chambers), after which it circulates through the different ventricles and exits into the subarachnoid space (SAS) around the brain, where it is reabsorbed into the venous system. If the fluid does not drain out of the brain or get reabsorbed, the ICP increases, which may lead to brain damage or death...

An 11-year-old female presented with orbital cellulitis, bacterial sinusitis, enlarged left superior ophthalmic vein, dural venous sinuses, and internal jugular vein. The patient underwent endoscopic sinus surgery and was started on intravenous antibiotics and anticoagulation with limited improvement in orbital signs and symptoms. A magnetic resonance imaging/magnetic resonance venography of the orbits and brain revealed a dilated left superior ophthalmic vein with absence of flow but no clearly discernible orbital abscess...

A previously fit and healthy 26-year-old lady with no significant medical history presented with a two-month history of headaches. The headaches were prolonged, generalised, and unusually severe for the patient. Examination revealed papilloedema. The patient's optic nerve sheath diameter was measured 3 mm posterior to the globe and found to be 7.5 mm. The patient subsequently had computed tomography scan of her brain that showed an optic nerve sheath diameter of 7.56 mm as measured 3 mm posterior to the globe...

BACKGROUND: Magnetic Resonance Guided Laser-Induced Thermal Therapy (MRgLITT) is a minimally invasive surgical procedure for ablating intracranial lesions. However, the presence of a fluid body can sequester thermal energy generated by the laser catheter.1-5 This compromises the performance of MRgLITT, and results in suboptimal ablation of cystic lesions. The authors report their surgical approach, namely stereotactic fluid aspiration followed by MRgLITT, on two patients with cystic brain tumors...

OBJECTIVE: The aim of this international survey was to investigate whether practice concerning drain insertion after burr hole drainage of cSDH following the publication of grade I evidence that it reduces recurrence rates has changed. Further, we aimed to document various practice modalities concerning the insertion of a drain adopted by neurosurgeons internationally. METHODS: We administered a survey to neurosurgeons all over the world with questions relating the surgical treatment of cSDH, emphasizing on their practices concerning the use of a drain...

BACKGROUND: Pott's puffy tumor is characterized by a fluctuate swelling of the frontal region as a result of osteomyelitis of the frontal bone. This inflammatory lesion may propagate endocranially resulting in acute meningitis, epidural abscess, subdural empyema, cavernous sinus trombophlebitis, cerebritis, and frontal lobe abscess of the brain. CASE REPORT: We present an unusual case of a 33-year-old man suffering from the Pott's puffy tumor whose condition was further complicated by a draining epidural-cutaneous fistula and an epidural abscess...

The 2004/2007 European Union (EU) enlargement by 12 member states offers a unique opportunity to quantify the impact of EU efforts to expand and integrate the scientific competitiveness of the European Research Area (ERA). We apply two causal estimation schemes to cross-border collaboration data extracted from millions of academic publications from 1996 to 2012, which are disaggregated across 14 subject areas and 32 European countries. Our results illustrate the unintended consequences following the 2004/2007 enlargement, namely, its negative impact on cross-border collaboration in science...

INTRODUCTION: The pathomechanism of a single subcortical infarct (SSI) may be better determined by assessing the perfusion status between parent artery and ischemic lesion. We aimed to compare the classifications into branch atheromatous disease (BAD) versus non-BAD based on diffusion-weighted imaging (DWI) or computed tomography perfusion (CTP), and to test whether a CTP-based classification improves the predicting power for progression in SSI (PSSI) compared to that by DWI. METHODS: We enrolled 109 consecutive patients with SSI examined by whole-supratentorial brain CTP and follow-up DWI...

Rupture of arteriovenous malformations (AVM) may be caused by venous outflow restriction, but there is no radiographic evidence of this. We report a case showing only a venous thrombus preceding intracranial haemorrhage from AVM. This is the first evidence that venous thrombus results in AVM rupture in its natural history.

The concept as to how the brain maintains its immune privilege has initially been based on observations that it is lacking classical lymph vessels and later, the absence of dendritic cells (DC). This view has been challenged by several groups demonstrating drainage/migration of injected tracers and cells into cervical lymph nodes (CLNs) and the presence of brain antigens in CLNs in the course of various brain pathologies. Using CD11c-diphtheria toxin receptor (DTR)-green fluorescent protein (GFP) transgenic (tg) mice, we have shown the existence of CD11c(+) cells, a main DC marker, within the brain parenchyma...

An infant with a history of atopic dermatitis presented to the emergency department on 5 occasions with flulike symptoms. Eventually, this child presented with signs of infection and increased intracranial pressure: fever, bulging anterior fontanel, and leukocytosis. A computed tomography scan identified a large frontal lobe brain abscess. The abscess was surgically drained; culture was positive for Staphylococcus aureus. The initial source of the infected brain abscess was explored. Ultimately, it was thought to be secondary to impetiginized atopic dermatitis, an unusual but serious consequence of a common skin condition...

BACKGROUND: In cases of severe traumatic brain injury (TBI), cerebrospinal fluid (CSF) diversion though an external ventricular drain (EVD) is a proven method to assist in the control of elevated intracranial pressure (ICP). Under normal circumstances, the EVD is placed in a frontal location. However, in cases of multifocal intracranial injury and swelling, collapse of the frontal horns of the lateral ventricles leads to frequent failure of frontal CSF drainage. In this series we describe the utility of the Keen's point EVD as a safe alternative to maintain continuous CSF diversion for patients in whom frontal drainage is not feasible...

A man in his late forties had lived as a recluse for more than ten years. He was found dead in his room. At autopsy, subarachnoid hemorrhage (SAH) was detected at the base of the brain, which weighed 1333 g. The cerebellar tonsil was swollen. The cerebral ventricle was enlarged and filled with blood. A hematoma was observed in the upper part of the left side of the cerebellar hemisphere. The location and size of SAH in this case indicated that the rupture of a cerebral aneurysm (CA) had occurred; however, CA was not detected...

Hypertension is associated with cognitive decline and various forms of dementia, including Alzheimer's disease. In animal models of hypertension, many of Alzheimer's disease characteristics are recapitulated, including brain atrophy, cognitive decline, amyloid β accumulation and blood brain barrier dysfunction. Removal of amyloid β and other waste products depends in part on clearance via the brain interstitial fluid (ISF). Here we studied the impact of hypertension on ISF drainage, using spontaneously hypertensive rats (SHR) and normotensive Wistar Kyoto rats (WKY)...

The human brain is an extremely complex system of 10(10)-10(11) neurons. To construct brain-like neuromorphic hardware, the neuron unit should be implemented effectively. Here, we report a neuron transistor based on a MoS2 flake, which has summation and threshold functions similar to biological neurons and may act as a basic neuron unit in neuromorphic hardware. The neuron transistor is composed of a floating gate and two control gates. A heavily doped silicon substrate serves as the floating gate, while the two control gates are capacitively coupled with the floating gate...

BACKGROUND: Dramatic increases in the migration of human resources for health (HRH) from developing countries like the Philippines can have consequences on the sustainability of health systems. In this paper, we trace the outflows of HRH from the Philippines, map out its key causes and consequences, and identify relevant policy responses. METHODS: This mixed method study employed a decentered, comparative approach that involved three phases: (a) a scoping review on health workers' migration of relevant policy documents and academic literature on health workers' migration from the Philippines; and primary data collection with (b) 37 key stakeholders and (c) household surveys with seven doctors, 329 nurses, 66 midwives, and 18 physical therapists...
