Central pontine myelinolysis (CPM), also known as osmotic demyelination syndrome, is a rare demyelinating disorder characterized by the loss of myelin in the center of the basis pontis. In this case report, an alcoholic patient with CPM and acquired demyelinating lesion of the basis pontis is described. The patient is a 70 year-old woman who presented with intermittent psychiatric symptoms and limb tremors following two months of alcohol abuse. During admission, magnetic resonance imaging (MRI) revealed hyperintensity on T2 weighted images and fluid-attenuated inversion-recovery imaging in the central pons without contrast enhancement...

Treatment of status epilepticus often requires highly sedative drugs with risk of side effects. Correct diagnosis is mandatory in order to prevent introduction of usefulness treatments. We report a case of suspected myoclonic status epilepticus. A thalamic lesion secondary to an osmotic demyelination syndrome was found to be the likely etiology of the myoclonus. Electrophysiological data (electroencephalography and electromyography) provided evidence for a subcortical origin of myoclonus and use of continuous EEG allowed monitoring of drug withdrawal...

Osmotic demyelination syndrome is an acute shift in serum osmolality causing demyelination, which may be due to rapid correction of hyponatremia, hyperglycaemia, hypokalemia and ketoacidosis. We present a case of 55yr old female and a known diabetic presented with the choreic movements involving left upper and lower limb for 2 days without any weakness.Her blood sugar was 428mg/dl at the time of admission with wide fluctuations.Her CT Brain showed hyperdensity in the right basal ganglia and the MRI brain showed hyperintense lesion in T2 weighted images showing features suggestive of osmotic demyelination...

White matter diseases include a wide spectrum of disorders that have in common impairment of normal myelination, either by secondary destruction of previously myelinated structures (demyelinating processes) or by primary abnormalities of myelin formation (dysmyelinating processes). The pathogenesis of many white matter diseases remains poorly understood. Demyelinating disorders are the object of this review and will be further divided into autoimmune, infectious, vascular, and toxic-metabolic processes. Autoimmune processes include multiple sclerosis and related diseases: tumefactive demyelinating lesions, Balo concentric sclerosis, Marburg and Schilder variants, neuromyelitis optica (Devic disease), acute disseminated encephalomyelitis, and acute hemorrhagic leukoencephalopathy (Hurst disease)...

Currently available guidelines in the acute management of severely symptomatic hypotonic hyponatremia vary in their approach to the use of hypertonic saline. In the acute setting, deciding on when to implement available treatment algorithm using hypertonic saline may be difficult, given that the duration of hyponatremia and potential alternative diagnoses presenting with similar symptoms may be hard to establish promptly. We present the case of a young female with symptomatic profound hyponatremia who subsequently developed osmotic demyelination syndrome due to rapid overcorrection of serum sodium concentration...

BACKGROUND: Improper correction of hyponatremia can cause severe complications, including osmotic demyelination syndrome (ODS). The Adrogué-Madias equation (AM), the Barsoum-Levine (BL) equation, the Electrolyte Free Water Clearance (EFWC) equation and the Nguyen-Kurtz (NK) equation are four derived equations based on the empirically derived Edelman equation for predicting sodium at a later time (Na2) from a known starting sodium (Na1), fluid/electrolyte composition and input and output volumes...

Extrapontine myelinolysis (EPM) is an uncommon disorder in children, with few pediatric cases reported to date. We report the first case of an infant with EPM without central pontine myelinolysis (CPM) presenting with severe hypernatremia. On admission, the infant had impaired consciousness, mild dehydration, and severe hypernatremia (190 mmol/L). The following day, the patient developed abnormal involuntary movements. Brain magnetic resonance imaging (MRI) confirmed EPM without CPM. He recovered without sequelae, and clinical examinations were within normal limits approximately 6 months after discharge...

In this report, we present the case of a 43-year-old woman with AIDS, disseminated aspergillosis, and malnutrition who developed osmotic demyelination syndrome. AIDS-related osmotic demyelination has only been documented in a handful of cases to date, and it appears independent of the classic mechanism of rapid correction of hyponatremia. In this manuscript, we review the six prior cases of osmotic demyelination in AIDS patients and compare their circumstances to that of our own patient. It appears that complications of malnutrition, possibly related to depletion of organic osmolytes in the central nervous system, may place AIDS patients at greater risk of osmotic demyelination...

Osmotic Demyelination Syndrome includes Central Pontine Myelinolysis and Extrapontine Myelinolysis. This condition has been described in cases of chronic Alcohol Dependence Syndrome and in rapid correction of hyponatremia. Though we frequently see patients with Alcohol Dependence Syndrome presenting with complicated withdrawal, Central Pontine Myelinolysis remains largely undetected and under-reported in literature. We present here a case of protracted Delirium Tremens where MRI brain revealed Central Pontine Myelinolysis...

REVIEW
S G Ball, Zohaib Iqbal
Hyponatraemia is the most common electrolyte abnormality encountered by physicians in the hospital setting. It is associated with increased mortality and length of hospital stay. However, the basis of the relationship of hyponatraemia with clinical outcome is not clear. Doubt remains as to whether the relationship is causal. It may reflect the association of two independent variables both of which are linked with disease severity. Serum sodium concentration is regulated through integrated neuro-humeral mechanisms that overlap with those regulating circulating volume...

Hyponatremia (serum sodium <135 mEq/L) is a common electrolyte disorder in community or hospitalized patients. Serum sodium levels should be corrected at a proper rate in patients with hyponatremia, since overcorrection of serum sodium levels is related to devastating neurologic consequences, such as the osmotic demyelination syndrome (ODS). However, a number of pitfalls, which could lead to undercorrection or overcorrection of hyponatremia, are common during the treatment of hyponatremic patients. Hereby, we describe ten common pitfalls that are observed during the correction of serum sodium concentration in hyponatremic patients...

Osmotic demyelination syndrome leading to central pontine/extra-pontine myelinolysis (CPM/EPM) occurs mainly in patients with history of alcohol abuse, malnourishment, following liver transplantation and less commonly, in association with other systemic diseases. Asymptomatic CPM/EPM is rare. Patients with end-stage renal disease (ESRD) who develop CPM/EPM are usually symptomatic with florid neurologic manifestations. Herein, we present a patient with ESRD on maintenance hemodialysis who was incidentally detected to have pontine and extra-pontine lesions suggestive of myelinolysis without any neurologic signs or symptoms...

Serum sodium concentration affects every cell in the body with respect to cellular tonicity. Hyponatremia is the most frequent electrolyte abnormality encountered, occurring at clinical admission in 22% of elderly patients. Any rapid correction of chronic severe hyponatremia can result in rapid cellular shrinking due to loss of intracellular free water. This is commonly associated with paralysis and severe brain damage due to osmotic demyelination syndrome (ODS). ODS occurs because the body has the ability to compensate for cellular fluid shifts due to chronic hyponatremia (by a decrease in brain concentration of several ions, amino acids, and organic osmolytes)...

ODS associated with hyperglycemia is rare, with few reports.Immune responses have been recently reported as a mechanism of ODS onset. In the present case, an autoimmune predisposition may have contributed to ODS pathogenesis.
