The use of peripheral blood rather than marrow has potential advantages for monitoring minimal residual disease during the treatment of leukaemia. To determine the feasibility of using blood, we used a sensitive polymerase chain reaction method to quantify leukaemia in the blood and marrow in 35 paired samples from 15 children during induction treatment.(More)
The association of small accessory marker chromosomes in man with specific abnormalities has been difficult to define owing to variations in the chromosome origin and the size of the markers. In a patient with typical Turner phenotype and a 45,X/46,X, + mar karyotype the marker was shown to be a small portion of the long arm of the X chromosome which(More)
The hindbrains and meninges of the pigeon and chick have been examined by light and electron microscopy. Serial section histology of the skull with the brain and meninges intact has shown that the caudal end of the roof of the fourth ventricle consists of an extensive membranous pouch which projects caudally and dorsally into the subarachnoid space.(More)
Many patients with acute lymphoblastic leukemia (ALL) are not cured by current therapy because of the development of drug resistance. It is not clear when resistance develops during the growth of the leukemic clone and whether resistant cells are already present at diagnosis or develop later during treatment. Twenty-two uniformly treated children with ALL(More)
AIM To determine whether there is any benefit in repeating the Pap smear at the time of colposcopy in women referred to a teaching hospital dysplasia clinic. METHODS Analysis of a computerised database, and review of literature. RESULTS Repeating the Pap smear potentially changed management in 2% of women referred with low-grade lesions, and in 7% of(More)
The level of minimal residual disease (MRD) in marrow early in treatment strongly predicts outcome in childhood acute lymphoblastic leukaemia (ALL). Using PCR we studied 30 pairs of aspirates and trephines taken during induction treatment. Consensus PCR primers showed a monoclonal gene rearrangement in eight pairs, polyclonal rearrangement in 18 pairs and a(More)
The Philadelphia translocation is associated with a poor prognosis in adults and children with acute lymphoblastic leukemia, even though the majority of patients achieve remission. To test the hypothesis that the translocation leads to drug resistance in vivo, we studied 61 children and 20 adults with acute lymphoblastic leukemia and used the level of(More)
Sensitive quantification of minimal residual disease (MRD) using the polymerase chain reaction (PCR) is strongly predictive of outcome in childhood acute lymphoblastic leukemia (ALL), with MRD levels at the end of induction therapy of >10(-3) predicting a poor outcome. Methods for sensitive quantification are, however, complicated and time-consuming.(More)
