Hyponatremia is the most common electrolyte disorder among hospitalized patients and it is sometimes considered as a poor outcome predictor. Its correction is thus indicated, even in asymptomatic patients. The conventional treatment is represented by fluid restriction in presence of euvolemia or hypervolemia; whereas loop diuretics are used in some hypervolemic conditions (cardiac heart failure, liver cirrhosis and nephrotic syndrome) and intravenous isotonic or hypertonic solution are administered in hypovolemic conditions...

The incidence of preeclampsia associated maternal and neonatal hyponatremia is reportedly rare and can be life threatening in severe cases. The timely diagnosis and careful management requires a multidisciplinary approach between obstetric, neonatal, endocrinology and intensive care teams. We report firstly, on a case of severe hyponatremia associated with preeclampsia, secondary to inappropriate Anti Diuretic Hormone secretion, followed by a review of cases over a one year period at our institution.

This study aims to evaluate the necessity of urgent neuroimaging for emergency admissions exhibiting symptomatology of profound hyponatremia. We retrospectively analyzed the medical records of all patients admitted to the emergency room of the University Hospital Münster from 2010 to 2014 with a serum sodium value < 125 mmol/L. From 52918 emergency admissions, 261 patients with profound hyponatremia were identified, of whom 140 (54%) had neurological symptoms. Unspecific weakness and confusion were the most prevalent of these symptoms (59%)...

Hyponatremia presents with various central nervous system symptoms during its course and treatment. We treated a patient who presented with a prolonged consciousness disorder and was suspected of having complications of neuroleptic malignant syndrome and osmotic demyelination syndrome (ODS) during the treatment for his hyponatremia, which was caused by syndrome of inappropriate secretion of antidiuretic hormone (SIADH). The patient was a 30-year-old Japanese man who had been under treatment for schizophrenia...

INTRODUCTION: Hyponatremic-hypertensive syndrome (HHS) is characterized by hypertension and hyponatremia. CASE PRESENTATION: We report a case of HHS in a 73-year-old woman, revealed by a hyponatremia leading to status epilepticus, without initial hypertension due to hypovolemia. She was successfully treated by endovascular therapy without any long-term supplementation or anti-hypertensive medication. CONCLUSION: Physiopathology hypothesis of HHS implicate pressure natriuresis, in this case, hypertension is not initially found and we discuss other hyponatremia mechanisms...

Hyponatremia is defined as a plasma sodium concentration less than 135 or 130 mEq/L (or mmol/L) and may be responsible for life threatening symptoms that can be observed in a variety of medical conditions. Cases of fatal hyponatremia have been reported in both clinical and forensic literature in situations of water intoxication due to psychogenic polydipsia, amphetamine derivative drug intake, high-endurance exercise, iatrogenic causes, and exceptional cases of child abuse by forced water intoxication. Vitreous sodium levels have been determined to be relatively stable during the early postmortem period and similar to levels found in normal serum of living subjects...

Electrolyte and acid-base disturbances are frequent in patients with end-stage liver disease; the underlying physiopathological mechanisms are often complex and represent a diagnostic and therapeutic challenge to the physician. Usually, these disorders do not develop in compensated cirrhotic patients, but with the onset of the classic complications of cirrhosis such as ascites, renal failure, spontaneous bacterial peritonitis and variceal bleeding, multiple electrolyte, and acid-base disturbances emerge. Hyponatremia parallels ascites formation and is a well-known trigger of hepatic encephalopathy; its management in this particular population poses a risky challenge due to the high susceptibility of cirrhotic patients to osmotic demyelination...

Human herpesvirus-6 (HHV-6) encephalitis and myelitis following allogeneic hematopoietic stem cell transplantation (HSCT) is frequently life-threatening. We retrospectively evaluated the clinical significance of hyponatremia in cases of HHV-6 encephalitis/myelitis. Using an institutional database and medical records, we identified and retrospectively analyzed 16 cases of HHV-6 encephalitis and/or myelitis after allogeneic HSCT. HHV-6 encephalitis and myelitis were defined as the symptoms/signs with HHV-6-DNA in the cerebrospinal fluid...

BACKGROUND: Acute mesenteric ischemia is often caused by embolization of the mesenteric arterial circulation. Coherent intestinal injury due to ischemia and following reperfusion get visible on macroscopic and histologic level. In previous studies, application of glycine caused an ameliorated intestinal damage after ischemia-reperfusion in rats. Because we speculated that glycine acted here as a signal molecule, we investigated whether the glycine-receptor agonist β-alanine evokes the same beneficial effect in intestinal ischemia-reperfusion...

INTRODUCTION: Dysnatremia commonly occur in the intensive care unit (ICU)- management of patients with aneurysmal subarachnoid hemorrhage (SAH). However, detailed management strategies have not been provided even by current guidelines. The purposes of this study were to examine the association of abnormal serum sodium levels with unfavorable neurologic outcomes and to identify the target range of serum sodium in patients with SAH. METHODS: We retrospectively reviewed all patients who were consecutively hospitalized with a confirmed diagnosis of SAH between January 2009 and December 2015...

CASE SUMMARY: A 10-year-old, 5.1 kg (11.2 lb), male castrated cat was presented with signs of lethargy and decreased appetite at home after being previously healthy. Serum biochemical analysis identified normokalemia (5.1 mmol/l; reference interval [RI] 3.4-5.6 mmol/l) and severe hyponatremia (123 mmol/l; RI 145-158 mmol/l), with an Na/K ratio of 24 (RI 32-41). Baseline serum cortisol was low to normal, but serum aldosterone was markedly decreased with a pre-adrenocorticotropic hormone stimulation concentration of 13 pmol/l (RI 194-388 pmol/l) and post-adrenocorticotropic hormone stimulation concentration of 21 pmol/l (RI 277-721 pmol/l)...

Tolvaptan is now well established as a potent pharmaceutical agent for symptomatic hyponatremia from syndrome of inappropriate antidiuretic hormone secretion (SIADH), congestive heart failure and liver cirrhosis. Previous studies had recruited older (63-65 years) patients with mild renal impairment (serum creatinine, 1.3-1.4 mg/dl). A 2012 report in the Journal of Neurology, Neurosurgery & Psychiatry described tolvaptan as a "lifesaving drug". A major outcome concern in the treatment of chronic hyponatremia is potentially fatal pontine demyelination from over-rapid correction of serum sodium >0...

Clinical decision support systems have been shown to improve practitioner performance. Most systems designed to prevent medication errors generate lists with patients who fulfill the criteria of the algorithm. These lists are reviewed by a pharmacist and physicians are contacted by telephone. Presenting pop-up alerts as part of the workflow with a clear recommendation is a feature critical to success. Therefore we implemented three algorithms in a clinical decision support system alerting during the medication ordering process...

INTRODUCTION: Tuberculous meningitis remains a major health issue in the community affecting young adults of both genders predominantly from rural background. In India, the disease continues to kill 2 people every 3 min or nearly 1000 daily, according to the Tuberculosis Control Society India. Tuberculosis (TB) of central nervous system (CNS) is the most devastating form of TB. As this disease is associated with very high prevalence in young adults and will ultimately contribute to great workforce loss, we decided to assess the factors deciding the disease and its course in our patients...

Dysnatremia is a common finding in the intensive care unit (ICU) and may be a predictor for mortality and poor clinical outcomes. Depending on the time of onset (ie, on admission vs later in the ICU stay), the incidence of dysnatremias in critically ill patients ranges from 6.9% to 15%, respectively. The symptoms of sodium derangement and their effect on brain physiology make early recognition and correction paramount in the neurologic ICU. Hyponatremia in brain injured patients can lead to life-threatening conditions such as seizures and may worsen cerebral edema and contribute to alterations in intracranial pressure...
