Two patients with central pontine myelinolysis are described. Both were middle aged women presenting with a history of protracted vomiting and drowsiness. Hyponatraemia (serum sodium 96 to 100 mmol/L) was a feature in both patients. No underlying malignancy, alcoholism, malnutrition or other serious disease was identified. Correction of electrolyte abnormalities was accompanied by deterioration in level of consciousness and development of a neurological syndrome characterized by quadriparesis, dysphasia and mutism. Death followed and histopathological examination confirmed classical myelinolysis in the central pons and extensive similar, though not identical, lesions in the cerebral hemispheres in both cases. The pathophysiological basis of the lesions is likely to be a special metabolic susceptibility of oligodendroglial cells in areas where neurones, glial cells and myelin sheaths lie in close proximity to one another.

Superior mesenteric artery syndrome is a rare cause of upper intestinal obstruction in both adults and children. Sixteen children with severe traumatic brain injury and spastic quadriparesis developed small intestinal obstruction while undergoing a rehabilitation programme between 1981 and 1990. Five patients met the roentgenographic diagnostic criteria. The presenting symptom was post-prandial bilious vomiting. The mean age was 13 (10-16) years. The mean time clapsed from injury to diagnosis was 53 days and from rehabilitation admission to diagnosis 22 days. The mean delay in diagnosis after onset of symptoms was 4 days. All patients were of disproportionately lower body weight in relation to height, with a mean weight loss of 7 kg. The mean percentile for weight was 18 and height 58, with a difference of 30 between height and weight percentiles. The patients were receiving nasogastric or gastrostomy tube feedings at the onset of the symptoms. All patients were treated non-surgically with gastric aspiration, nasojejunal or gastrojejunal feeding by passing a feeding tube distal to obstruction. No patient required intravenous hyperalimentation. There was no recurrence in any patient during the follow-up period of 1-5 years. Though rare, superior mesenteric artery syndrome can develop in brain-injured children with spastic quadriparesis, prolonged recumbency and recent weight loss. Increased awareness of occurrence of this condition and timely management will decrease morbidity and complications that may interfere with recovery.

Patients with eating disorders often use diuretics to eliminate fluid to achieve lower body weight. Diuretic abuse can lead to severe hyponatremia. Central pontine myelinolysis, a disruption of the myelinated neurons of the pons, has been associated with rapid correction of severe hyponatremia. A case is presented of a 35-year-old woman who was brought to the emergency service by ambulance complaining of vomiting for 7 days and that she could not hear well because she was 'worn out'. Initial laboratory values included serum Na 91 mEq/l, K 1.6, Cl 46, bicarbonate 33, BUN 4 mg/dl, glucose 306 mg/dl. After 32 h of intravenous fluids, the serum Na was 126, K 4.0, Cl 89, bicarbonate 25, glucose 118 mg/dl. On the 3rd hospital day the serum Na was 139. On the 4th hospital day she was alert and appropriate. On the 5th hospital day, however, she was confabulating and chatty. The serum Na was 139. She progressed to develop a spastic quadriparesis, speech and swallowing difficulties. A magnetic resonance imaging scan showed central pontine myelinolysis. She acknowledged taking 400 mg daily of furosemide and drinking much water. She had a past history of anorexia nervosa. She had a residual weight phobia and strove to keep her weight below 106 lb. Her height was 5 feet, 6 inches. As illustrated by this case, diuretic abuse can cause severe hyponatremia and the subsequent risk of central pontine myelinolysis. In patients with severe chronic or subacute hyponatremia, a safe restoration rate for serum Na has been less than 0.55 mEq/l/h. Serum Na should be below 135 within the first 48 h and hypernatremia should be avoided.

A successful case undergoing the ECA-PCA bypass operation with the use of an interposition saphenous venous graft for vertebrobasilar progressing stroke was reported and details of the operative techniques were described. A 40-year-old man was admitted because of confused mental state following sudden onset of headache, vomiting, vertigo, and ataxic gait. Neurological examinations revealed he was confused and restless, and left-sided Weber's syndrome, bulbar palsy and dysphasia were noticed. CT scan showed multiple small low density areas with no enhancement scattering in both occipital lobes and cerebellar hemispheres. Angiographical studies showed that the left vertebral artery was occluded at the vertebrobasilar junction and the right vertebral artery stenosed up to 90% or more at the branching site of the PICA. There was no visualization of the vertebrobasilar system through the right posterior communicating artery. The left posterior communicating artery was not examined. The patient was treated with Urokinase amounting to 740,000 units for ten days. Thirteen days later, however, he became progressively drowsy and he became unable to speak and swallow. Quadriparesis also appeared. Progressive deterioration of these brain stem ischemic symptoms was assumed to originate from critically lowered perfusion of the vertebrobasilar circulation. Therefore, the ECA-PCA anastomosis by means of a venous graft was carried out on the right side in expectation of the rapid restoration of the blood flow in the affected brain stem. A venous graft was chosen because it would carry larger amount of blood immediately after completing the bypass surgery than small calibered arterial graft such as a superficial temporal artery.(ABSTRACT TRUNCATED AT 250 WORDS)

A 76-year-old female presented with vertebrobasilar insufficiency due to a severe stenosis of the right primitive hypoglossal artery (an unusual carotid-basilar anastomosis) manifesting as recurrent transient ischemic attacks (TIA) associated with quadriparesis and cerebellar ataxia with vertigo, nausea, and vomiting. She had been treated with 100 mg of aspirin per day, but TIA associated with the same symptoms persisted. Cerebral blood flow (CBF) studies disclosed a region of moderately low flow in the posterior fossa. Cerebral angiography demonstrated that the posterior fossa was supplied via the right primitive hypoglossal artery, which was severely stenotic at its origin. Percutaneous transluminal angioplasty using a Stealth catheter, 3.0-mm diameter and 10-mm long, successfully dilated the stenosis. No TIA occurred postoperatively, and a marked increase in CBF was demonstrated in the posterior fossa.

A 49-year-old woman, with a two-year-history of multiple screlosis (MS), noticed postural dizziness, intractable hiccups and vomiting. On admission, she had mild quadriparesis, hypesthesia below the C5 level, and a girdle sensation at the T5 and L1 levels. A CSF examination showed slight increases in the protein level (48 mg/dl) and cell count (7/mm3). Brain MRI demonstrated no obvious lesion in the medulla oblongata. The head-up-tilting test showed a decrease in the blood pressure from 105/63 mmHg to 70/55 mmHg. The pulse rate, however, increased from 57/min to 72/min. The cold pressure test also revealed a mild impairement in her blood pressure response. The R-R interval variation (coefficient of variation: CVRR) during normal breathing was 2.58 (normal: > 1.66). The valsalva ratio was 1.84 (normal: 1.4-2.0). The Aschner eye-ball pressure test, the blood pressure response to the injection of epinephrine, and the sweating response to the injection of acetylcholine were all normal. She was thus administered domperidone and chlorpromazine. Only domperidone effectively improved the nausea and vomiting. All symptoms, including orthostatic hypotension, hiccups and vomiting, disappeared about one month after admission. The remission of her symptoms was considered to reflect the natural course of MS. The results of autonomic nervous system function tests and her clinical features suggest that an irritable lesion in the medullary tegmentum, including the nucleus tractus solitarii, most likely caused her symptoms. The above findings indicate that autonomic symptoms, such as orthstatic hypotension, hiccups and vomiting, may sometimes be the only symptoms observed in a relapse of MS.

A 9-year-old girl was admitted for the treatment of hyper-natremic dehydration. Her history was significant for psychogenic polydipsia, hyponatremia, and a renal concentrating defect. She presented with a 2-day history of altered mental status, ataxia, lethargy, fever, nausea, vomiting, and diarrhea. Meningitis was ruled out. Over the course of her illness, slow rehydration was maintained with a gradual decrease (10 mEq per 24 hours) of the serum sodium. Despite this care, she developed quadriparesis, and magnetic resonance imaging performed on day 6 of her illness was consistent with osmotic demyelination (central pontine myelinolysis). To rule out an excessively rapid correction of hypernatremia as the etiology of the problem, a myelin basic protein was measured in the cerebrospinal fluid that had been obtained on hospital day 1. The myelin basic protein was 649.50 ng/mL (normal, 0.07-4.10 ng/mL). The current literature is presented regarding the postulated pathogenesis of central pontine myelinolysis and suggested therapies, previous reports of central pontine myelinolysis in children are reviewed, and the potential role of myelin basic protein in its diagnosis is discussed.

A 19-year-old immunocompetent man was admitted to hospital with diplopia, nausea, vomiting and change in mental status. The patient had a history of tuberculous meningitis that was diagnosed at another hospital 6 months before the present admission, and at that time anti-tuberculosis treatment was initiated using a first-line drug combination. A computed tomography (CT) scan of the brain revealed non-communicating hydrocephalus. A ventriculo-peritoneal shunt was inserted surgically. Two months later, the patient was hospitalized again for fever, dysphagia and left hemiparesis. At that time, his cranial CT findings were within normal limits; however, magnetic resonance imaging (MRI) revealed an irregular multilocular peripheral contrast-enhancing lesion in the posterior fossa. The abscess was surgically drained. The presence of acid-fast bacilli in the abscess material was demonstrated by Ziehl-Neelsen staining. Mycobacterium tuberculosis grew on Lowenstein-Jensen culture medium, and the strain was found to be resistant to isoniazid. One month after the operation, the patient became quadriparetic. Cervical MRI revealed a cervico-thoracic syringomyelitic cavity, after which a syringoperitoneal shunt was placed. Treatment with four drugs was continued for 10 months, and then treatment with three drugs for a total period of 18 months. The patient recovered, with residual quadriparesis. Even though very rare, isoniazid-resistant M. tuberculosis may be the causative agent of progressive tuberculosis.

Ascariasis is one of the most common helminthic infestations in humans. Massive infestation can give rise to serious complications such as intestinal obstruction. We present a 4-year-old boy, who presented with acute flaccid quadriparesis due to the hypokalemic alkalosis induced by severe vomiting. Severe vomiting was due to intestinal obstruction caused by round worms.

Stem cell transplantation is an investigational therapy for multiple sclerosis. The authors describe a case of catastrophic demyelinating encephalomyelitis following stem cell transplantation in a 17-year-old girl. Nine months after an initial diagnosis of multiple sclerosis, she underwent stem cell transplantation in Costa Rica. Subsequently, she deteriorated and was transported back to the United States with headache and vomiting progressing to quadriparesis, locked-in syndrome, and superimposed encephalopathy. Magnetic resonance imaging and brain biopsy were consistent with fulminant demyelinating encephalomyelitis with enhancing parenchyma and leptomeninges. Cerebrospinal fluid analysis revealed lymphocytic pleocytosis and high protein. The protracted illness required tracheostomy and gastrostomy. After methyleprednisone, intravenous immunoglobulin, and cyclophosphamide, she improved during 2.5 months to an ambulatory, functionally independent state. Subsequently, typical less severe multiple sclerosis relapses occurred. This case demonstrates that stem cell transplantation may provoke life-threatening encephalomyelitis in patients with multiple sclerosis. This highlights the need to restrict transplantation to trials with appropriate safety controls.
