Atypical childhood Wilson's disease.
ABSTRACT Wilson's disease is a genetic disorder of copper metabolism with a hepatic or neurologic presentation. A hepatic presentation is more common in young children. Neurologic Wilson's disease often manifests as a movement disorder with dystonia, tremor, and dysarthria. Psychiatric or behavioral symptoms can also be a presenting feature of Wilson's disease. We describe an atypical neurologic presentation in a prepubertal child with minimal hepatic involvement; in which transient hemiparesis and encephalopathy dominated her initial neurologic presentation. Brain magnetic resonance imaging revealed extensive cortical and subcortical signal change, in addition to the classical basal ganglia signal abnormality observed in Wilson's disease. She was treated with oral tetrathiomolybdate anticopper therapy, followed by zinc maintenance. Her clinical status and brain imaging improved considerably at 1 year after treatment initiation. Neurologic Wilson's disease may have diverse presentations, and should be considered in children who present with cortical features and signal change on magnetic resonance imaging.

ABSTRACT: BACKGROUND: dysarthria in Wilson's disease. PROCEDURES: case study of two patients with disease's diagnosis, both young female adults, with six years of schooling. Perceptual analysis was done by four speech therapists. The following parameters were assessed: voice quality, loudness, pitch, vocal attack, vocal stability and resonance, as well as the degree of deviated parameters, measured by a visual analogue scale. In addition, the intelligibility was analysed by an orthographic transcription method. Praat 4.4.13 software was used for acoustic analysis. Fundamental frequency, phonatory stability, noise and temporal measures were equally assessed. RESULTS: both patients have a speech characterized by: maximum phonation time reduced, breathiness and strained harsh voice quality, voice stoppages, transient breathiness, increased shimmer and noise-to-harmonics ratio, hypernasality. Oral diadochokinesia, speech rate and intelligibility of speech were reduced. The results suggested that the patient who showed Wilson's disease for longer time showed more acute impairments in most of the analyzed perceptual and acoustic parameters. CONCLUSION: both cases showed similar caracteristics. These features seem to be typical in dysarthric patients with Wilson's disease. However, differences were also observed, and can be related to the disease's evolution.Revista CEFAC 06/2010; 12(3):509-515.

ABSTRACT: Tremor is defined as a rhythmic, involuntary, oscillatory movement of body parts. Although constituting nearly 20% of presentations with paediatric movement disorders, tremor in childhood, beginning in the neonatal period, has rarely been described in the literature. Tremor may be an isolated finding or a part of associated neurological or systemic disorders. In this review we aim to discuss the classification, aetiology, clinical features and management of various tremor syndromes in childhood.Archives of Disease in Childhood - Education and Practice 01/2014; · 1.46 Impact Factor

ABSTRACT: We report the case of a 10-year old boy who had been diagnosed with megalencephalic leukoencephalopathy several years earlier. Because of the patient's oral dystonic activity, a traumatic, nonhealing, chronic ulcer had developed on his lower lip. Botox-A was injected into the mentalis, orbicularis oris, and bilateral masseter muscles. The patient showed decreased dystonia and gradual complete healing of the traumatic ulcer of the lower lip. The treatment of patients with self-mutilation to the lips will often be difficult. Traditionally, patients have been treated with various medications, oral appliances, and even tooth extraction. The results of the present case report suggest that Botox should be considered as a possible first-line strategy, along with oral appliances.Journal of oral and maxillofacial surgery: official journal of the American Association of Oral and Maxillofacial Surgeons 02/2014; · 1.58 Impact Factor
