Here, we present 2 patients who developed central pontine myelinolysis after living-donor liver transplant. Both patients had abnormal sodium level before living-donor liver transplant. Patient 1 presented with severe hyponatremia on admission. After administration of 3% saline, her sodium level during the first 24 hours was kept at 100 mEq/L and then increased to 116 mEq/L during the next 24 hours. The level increased 5.8 mEq/L during the 4- to 5-hour transplant procedure. Patient 2 was admitted to the hospital with an unprovoked seizure...

Hydrofluoric acid (HF), a dangerous inorganic acid, is widely used in various industries and in daily life. Chemical burns caused by HF exposure occur more frequently in some regions worldwide. It has been reported that some cases with HF burns can be lethal due to the hypertoxicity of HF. In this article, we present a case of a 24-year-old worker who suffered HF burns by 53% HF solution to his face, neck, and nasal cavity. This patient quickly developed electrolyte disturbance, that is, hypocalcemia, and hypopotassemia, and myocardial injury after exposure...

A E Macias-Medri, Jacinto A Liendo, Ricardo J Silva
A hybrid simulation model (macro-molecular dynamics and Monte Carlo method) is proposed to reproduce neurosecretion and exocytosis. A theory has been developed for vesicular dynamics based on quasi-static electric interactions and a simple transition-state model for the vesicular fusion. Under the non-equilibrium electric conditions in an electrolytic fluid, it is considered that the motion of each synaptic vesicle is influenced by electrostatic forces exerted by the membranes of the synaptic bouton, other vesicles, the intracellular and intravesicular fluids, and external elements to the neuron...

BACKGROUND: Periodic lack of availability and high cost of commercially produced isotonic fluids for intravenous (IV) use in horses have increasingly led to use of home-made or commercially compound fluids by veterinarians. Data regarding the quality control and safety of compounded fluids would be of benefit to equine veterinarians. OBJECTIVES: To compare electrolyte concentrations, sterility, and endotoxin contamination of commercially available fluids to 2 forms of compounded isotonic crystalloid fluids intended for IV use in horses...

Background Despite the potential of clinical practice guidelines to improve patient outcomes, adherence to guidelines by prescribers is inconsistent. Objective The aim of the study was to determine whether an approach of introducing an educational programme for prescribers in the hospital combined with audit and feedback by the hospital pharmacist reduces non-adherence of prescribing physicians to key pharmacotherapeutic guidelines. Setting This prospective intervention study with a before-after design evaluated patients at surgical, urological and orthopaedic wards...

Long-term home parenteral nutrition (LTPN) in children with chronic intestinal failure (CIF) is associated with renal complications such as fluid and electrolyte imbalances, nephrocalcinosis, nephrolithiasis and chronic kidney disease (CKD). The etiology of CIF-associated nephropathy is multifactorial. The aim of this study was to evaluate renal involvement under LTPN. In this study 50 patients with CIF, median age 4.2 years (1.4 - 9.3, 23 female) were included. Kidney involvement was a frequent finding in this study...

We review the high pressure forced intrusion studies of water in hydrophobic microporous materials such as zeolites and MOFs, a field of research that has emerged some 15 years ago and is now very active. Many of these studies are aimed at investigating the possibility of using these systems as energy storage devices. A series of all-silica zeolites (zeosil) frameworks were found suitable for reversible energy storage because of their stability with respect to hydrolysis after several water intrusion-extrusion cycles...

Home parenteral nutrition (HPN) has benefited countless patients since its initiation almost 5 decades ago. Over time, HPN has been found to be associated with various complications, including metabolic disorders. Metabolic complications can be grouped into short-term (eg, fluid imbalance, electrolyte disturbances, glucose abnormalities) and long-term (eg, hepatobiliary disorders, metabolic bone disease, iron deficiency anemia, manganese toxicity) categories. There are a number of treatment options for each complication...

We analyze the effects of an externally applied electric field on thermal fluctuations for a binary electrolyte fluid. We show that the fluctuating Poisson-Nernst-Planck (PNP) equations for charged multispecies diffusion coupled with the fluctuating fluid momentum equation result in enhanced charge transport via a mechanism distinct from the well-known enhancement of mass transport that accompanies giant fluctuations. Although the mass and charge transport occurs by advection by thermal velocity fluctuations, it can macroscopically be represented as electrodiffusion with renormalized electric conductivity and a nonzero cation-anion diffusion coefficient...

An automated system was developed to measure the viscosity of fluids as a function of temperature using image analysis tracking software. An Ostwald viscometer was placed in a three-wall dewar in which ethylene glycol was circulated using a thermal bath. The system collected continuous measurements during both heating and cooling cycles exhibiting no hysteresis. The use of video tracking analysis software greatly reduced the measurement errors associated with measuring the time required for the meniscus to pass through the markings on the viscometer...

BACKGROUND: Due to the high prevalence of EIPH in racehorses and its potential impact on the horse's health, furosemide administration is permitted up to 4-h prior to post time in most North American racing jurisdictions. Anecdotal reports suggest that administration of furosemide 24-h prior to strenuous exercise may be equally effective in decreasing the severity of EIPH. OBJECTIVES: (1) compare the efficacy of furosemide in reducing the presence and severity of EIPH when administered 4 or 24-h prior to strenuous exercise (2) characterise electrolyte and blood parameters following administration of furosemide at 4- and 24-h prior to exercise...

A theoretical study on the gel electrophoresis of a charged particle incorporating the effects of dielectric polarization and surface hydrophobicity at the particle-liquid interface is made. A simplified model based on the weak applied field and low charge density assumption is also presented and compared with the full numerical model for a nonpolarizable particle to elucidate the nonlinear effects such as double layer polarization and relaxation as well as surface conduction. The main motivation of this study is to analyze the electrophoresis of the surface functionalized nanoparticle with tunable hydrophobicity or charged fluid drop in gel medium by considering the electrokinetic effects and hydrodynamic interactions between the particle and the gel medium...

Early diagnosis of Bartter syndrome (BS) in the neonatal period is a clinical challenge, more so in an extremely low birth weight (ELBW) baby because of the inherent renal immaturity and the associated difficulty in fluid management. However, once a diagnosis is made, the disorder is known to respond well to fluid and electrolyte management, prostaglandin inhibitors, and potassium-sparing diuretics. Herein, we report a case of neonatal BS in a very premature ELBW infant.
