Background: Low brain tissue oxygen tension (PbtO2 ), or brain hypoxia, is an independent predictor of poor outcome. Increasing inspirational fraction of oxygen could have a significant influence on treating lower PbtO2 . Combined PbtO2 therapy, compared to the approach that focus only on regulation of cerebral perfusion pressure and intracranial pressure, shows better patient outcomes. Monitoring of PbtO2 could be helpful in individualizing treatment, preventing or limiting secondary brain injury, and maintaining better patient outcome...

Idiopathic intracranial hypertension (IIH) is associated with obesity, and weight loss is important to reduce intracranial pressure and improve visual function. A 38-year-old woman with IIH followed an extreme diet, which resulted in 30% weight loss (BMI moved from 34.9 to 24.6). Weight loss resulted in a significant reduction of papilloedema, normalization of intracranial pressure and improvement in headache pattern, but also induced a state of initial malnutrition, relevant depression and disability. She was discharged with the indication to start a controlled diet and improve physical activity: clinical situation get back to stability, with the patient loosing further weight (BMI=21...

Prenatal, neonatal meningoencephalitis and infections of the brain in older infants are often associated with serious complications which can be diagnosed by sonography through the open fontanelles. Most frequently postmeningitic hydrocephalus and subdural effusions occur. Rarer complications are brain abscesses and ventriculitis which are caused by gram negative bacteria such as E. coli, Serratia marcescens, Proteus and Enterobacter. A serious complication after ventriculitis is the development of compartment hydrocephalus...

Special Operations Forces and their accompanying tactical multipurpose canines (MPCs) who are involved in repeated live-fire exercises and military operations have the potential for increased blood lead levels and toxicity due to aerosolized and environmental lead debris. Clinical lead-toxicity symptoms can mimic other medical disorders, rendering accurate diagnosis more challenging. The objective of this study was to examine baseline lead levels of MPCs exposed to indoor firing ranges compared with those of nontactical military working dogs (MWDs) with limited or no exposure to the same environment...

We investigated the occurrence of metal-based nanoparticles in a natural system, the river Dommel in the Netherlands. The river itself is well-studied as far as hydrology and water quality is concerned, easily accessible and contains one major wastewater treatment plant discharging onto this river. We sampled water from various locations along the river and collected samples of influent, effluent and sewage sludge from the wastewater treatment plant. The sampling campaign was carried out in June 2015 and these samples were analysed for seven elements using high-resolution inductively coupled plasma mass spectrometry (HR-ICP-MS), ultrafiltration with a sequence of mesh sizes and scanning electron microscopy (SEM)...

Radiological assessment of the head is a routine part of the management of traumatic brain injury. This assessment can help to determine the requirement for invasive intracranial pressure (ICP) monitoring. The radiological correlates of elevated ICP have been widely studied in adults but far fewer specific pediatric studies have been conducted. There is, however, growing evidence that there are important differences in the radiological presentations of elevated ICP between children and adults; a reflection of the anatomical and physiological differences, as well as a difference in the pathophysiology of brain injury in children...

PURPOSE OF REVIEW: Pain management in neurocritical care is a subject often avoided because of concerns over the side-effects of analgesics and the potential to cause additional neurological injury with treatment. The sedation and hypercapnia caused by opioids have been feared to mask the neurological examination and contribute to elevations in intracranial pressure. Nevertheless, increasing attention to patient satisfaction has sparked a resurgence in pain management. As opioids have remained at the core of analgesic therapy, the increasing attention to pain has contributed to a growing epidemic of opioid dependence...

Among other applications, metal-organic frameworks (MOFs) are slowly gaining grounds as fillers for desalination composite membranes. In this study, superhydrophobic poly (vinylidene fluoride) (PVDF) nanofibrous membranes were fabricated with MOF (Iron-BTC) loading of up to 5 wt.% via electro-spinning on a nonwoven substrate. To improve attachment of nanofibers unto the substrate, a substrate pre-treatment method called 'solvent basing' was employed. Iron content in the nanofiber, measured by dispersive X-ray spectroscopy (EDS), increased proportionally with the increase of MOF concentration in the spinning dope, indicating a uniform distribution of MOF in the nanofiber...

BACKGROUND: Cerebral mitochondrial dysfunction is prominent in the pathophysiology of severe bacterial meningitis. In the present study, we hypothesize that the metabolic changes seen after intracisternal lipopolysaccharide (LPS) injection in a piglet model of meningitis is compatible with mitochondrial dysfunction and resembles the metabolic patterns seen in patients with bacterial meningitis. METHODS: Eight pigs received LPS injection in cisterna magna, and four pigs received NaCl in cisterna magna as a control...

PURPOSE: Biometals such as zinc and copper have been shown to affect tight junction expression and subsequently blood-brain barrier (BBB) integrity. Whether these biometals also influence the expression and function of BBB transporters such as P-glycoprotein (P-gp) however is currently unknown. METHODS: Using the immortalised human cerebral microvascular endothelial (hCMEC/D3) cell line, an in-cell western assay (alongside western blotting) assessed relative P-gp expression after treatment with the metal ionophore clioquinol and biometals zinc and copper...

Headache is an uncommon symptom in Guillain-Barré syndrome (GBS). We review four clinical settings related to GBS in which headache may be present. We focus on pathophysiological explanations, alerting the clinician to further potential investigations and treatment. Most reports of headache in GBS occur in the context of the posterior reversible encephalopathy syndrome, an increasingly recognized dysautonomia-related GBS complication. Less frequent is headache in the setting of increased intracranial pressure and papilledema (secondary intracranial hypertension), Miller Fisher syndrome, and cerebral venous sinus thrombosis...

A detection system based on Laser Induced Breakdown Spectroscopy (LIBS) was designed, optimized, and successfully employed for the estimation of lead (Pb) content in drilling fueled soil (DFS) collected from oil field drilling areas in Pakistan. The concentration of Pb was evaluated by the standard calibration curve method as well as by using an approach based on the integrated intensity of strongest emission of an element of interest. Remarkably, our investigation clearly demonstrated that the concentration of Pb in drilling fueled soil collected at the exact drilling site was greater than the safe permissible limits...

The results of a toxicity analysis showed differences from those of the existing experimental data. Therefore, HPLC-ICP-MS was used to analyze the soluble arsenic content at different valences in realgar prepared with water grind processing, which were collected from 3 companies. The results showed that the free arsenic of the 3 companies did not exceed the limit of Chinese Pharmacopoeia. However, if the free arsenic was calculated based on the total value of As(Ⅲ) + As(Ⅴ), free arsenic of 1 company exceeded the limit of Chinese Pharmacopoeia...
