polycythemia/seizures

Polycythemia--characterized by an excessive number of erythrocytes--is a rare disease in the dog with a chronic progressive course and unspecific symptoms. There are several forms: a primary, a secondary adequate or a secondary inadequate polycythemia. The clinical workup is done step by step and

Polycythemia vera, a rare and poorly documented disease in cats, was diagnosed in a 4-year-old domestic shorthair cat admitted because of seizures. The diagnosis was made on the basis of high PCV, normal serum erythropoietin concentration (as determined by bioassay, using rabbit bone marrow cells),

UNASSIGNED A retrospective multicentre case series of feline primary erythrocytosis (PE) was evaluated. The aim was to gain better understanding of disease presentation and progression to guide management and prognostication. Case records were assessed for evidence of increased packed cell volume

Transient erythrocytosis during the neonatal period may result in serious complications. Among the well recognized problems are respiratory distress, acute heart failure, and death. Little attention has been ascribed to the neurologic complications of a high hematocrit level in the neonatal period.

Partial exchange transfusion (PET) is traditionally suggested as treatment for neonates diagnosed with polycythemia. Nevertheless, justification of this treatment is controversial. We evaluated the risk for short-term complications associated with a restrictive treatment protocol for neonatal

BACKGROUND Cerebral arteriovenous malformations (AVM) usually present with headache, hemorrhage, or seizure. Erythropoietin (EPO) has demonstrated protective effects against ischemia within the CNS. METHODS The authors report a patient with a cerebral AVM and concurrent polycythemia associated with

Hepatoblastoma (HB) is a rare malignant tumour of the liver and usually occurs in the first three years of life. Hepatoblastoma in adolescents and young adults is extremely rare; nevertheless the prognosis is much worse than in childhood, because these kinds of tumours are usually diagnosed late.

A 1-year-old neutered male Labrador retriever mixed breed dog was referred for peracute onset of ataxia and seizures. Hematocrit at presentation was 84%. Magnetic resonance imaging of the brain revealed a lesion in the right caudate nucleus consistent with infarction. Postmortem findings were

A child had neonatal polycythemia, severe seizures beginning at 6 weeks of age, and a computerized tomography scan showing multiple cerebral infarcts. Follow-up showed substantial developmental delay with spastic quadriplegia. This case illustrates that neonatal polycythemia is a rare but

We describe the clinical syndrome, medical management, etiology, and neurologic outcome of stroke diagnosed by computed tomographic scan in 11 full-term neonates encountered during a two-year period. Neonatal stroke is relatively common and may appear in the setting of diverse cerebrovascular

Migraine-like cerebral transient ischemic attacks (MIAs) and ocular ischemic manifestations were the main presenting features in 10 JAK2(V617F)-positive patients studied, with essential thrombocythemia (ET) in 6 and polycythemia vera (PV) in 4. Symptoms varied and included cerebral ischemic attacks,

BACKGROUND Pulmonary alveolar microlithiasis is an autosomal recessive disease in which a mutation in the SLC34A2 gene that codes for a sodium phosphate type IIb transporter protein (expressed in human epithelial tissues and functions in the clearance of phosphate ions) leads to the formation of
