A long-term follow-up study was carried out to assess ototoxicity in children who had been treated for a malignant tumour with "standard dose" cisplatin (60-100 mg/m2 per course), and were at least 2 years from stopping treatment. The median age at diagnosis was 2 years 2 months (range 1 month to 13.5 years). On the basis of hearing assessment by pure-tone(More)
To evaluate the long-term renal toxicity of cisplatin, 40 children who had been without treatment at least 18 months (range 18 months to 7 years) were observed. In all the children, glomerular filtration rate (GFR) was estimated from the plasma clearance of chromium 51-labeled ethylenediaminetetraacetic acid, both at the end of treatment and at a median(More)
Loss of heterozygosity at loci on the short arm of chromosome 11 has been reported in 31% (11/38) of Wilms' tumours in our series. Lymphoblastoid cell lines were prepared from the parents of 10/11 of the patients showing allele loss in their tumours. In 9 of the cases, where the parental origin of the alleles could be followed, it was the paternal alleles(More)
Ten children with Langerhans cell histiocytosis (histiocytosis X) either resistant to or intolerant of corticosteroids received etoposide (VP16). Nine responded. In one instance, partial diabetes insipidus was temporarily reversed. There was no major toxicity. Etoposide should be seriously considered as therapy for patients with LCH in whom the(More)
Pairs of tumour and normal DNA samples from 38 Wilms' tumour patients have been investigated for loss of heterozygosity using 12 probes from chromosome 11. Allele loss was detected in only 11 cases (31%). Densitometric analysis showed that allele loss was not due to non-disjunction or hemizygous deletion, but rather to mitotic recombination or(More)
Chronic exposure to manganese (Mn) produces a spectrum of cognitive and behavioral deficits associated with a neurodegenerative disorder resembling Parkinson's disease. The effects of high-dose exposure to Mn in occupational cohorts and in adult rodent models of the disease are well described but much less is known about the behavioral and neurochemical(More)
Fifty eight children with Langerhans cell histiocytosis who were referred to this hospital between 1980 and 1987 were studied. Fourteen had single system disease, and 44 had multisystem disease, of whom 22 had vital organ dysfunction. A conservative approach to treatment was adopted, and when systemic treatment was indicated a short course of prednisolone(More)
In order to document anterior pituitary dysfunction in patients with biopsy-proven Langerhans cell histiocytosis (LCH) and diabetes insipidus and to correlate this with structural changes on imaging, we performed an insulin tolerance test, enhanced computed tomography (CT), and unenhanced magnetic resonance imaging (MRI) in nine patients. Six of the nine(More)
UNLABELLED The tolerance to and toxicity of cisplatin treatment was retrospectively studied in 30 infants. A total of 191 courses were given with a median of six per child and a median cumulative dose of 400 mg m-2. Electrolyte disturbances were noted in 15/23 infants (38:144 courses): hypomagnesaemia, which was dose related, in 10/23 (25/144 courses),(More)
