- Hepatocellular carcinoma and obliterated hepatic bile duct were found at postmortem examination in a 4-year-old girl with arteriohepatic dysplasia (Alagille's syndrome). AFP level was extremely high. Liver cirrhosis was present on percutaneous needle biopsy 9 months before she succumbed in progressive liver failure. Episodes of repeated gastrointestinal, life-threatening hemorrhages occurred during the last 6 months of her life. Histopathologic findings of the eyes were documented at autopsy.

- Concentrations of ara-CTP in leukemic cells isolated from CSF and of ara-C in lumbar CSF were measured following intraventricular ara-C administration in two girls with refractory meningeal leukemia. CSF samples were collected with a permanent intrathecal-lumbar catheter. In contrast to the comparatively short retention of ara-C in the CSF (t1/2 1.8 to 2.9 hours), there was a high accumulation and an extremely long retention of ara-CTP in the leukemic cells (t1/2 8.1 to 36 hours). The patients included in this study had an ara-C-resistant disease. No obvious relationship was seen between concentrations of ara-C in the CSF and of ara-CTP in the leukemic cells. Similar studies were performed after simultaneous intraventricular administration of hydrocortison and ara-C. Hydrocortison did not increase ara-CTP retention in the leukemic cells, nor did it effect CSF pleocytosis.

Platelet surface-bound IgG and platelet-specific IgG in plasma in childhood thrombocytopenia
- 1990

Ingår i: Acta Paediatrica Scandinavica. - : Wiley. - 0001-656X .- 0803-5253 .- 1651-2227. ; 79:3, s. 328-334

- Quantification of platelet-bound immunoglobulin is widely used in the evaluation of thrombocytopenia. Several methods have been devised among which labelled ligand-binding assays seem to be most appropriate. In series of adult patients such assays have been shown to be superior in separating immune-thrombocytopenia from thrombocytopenia of non-immune causes. We studied 62 children with thrombocytopenia of various causes, using radiolabelled protein A as a ligand to measure platelet-surface bound IgG. The test was highly sensitive (93%) in detecting immune-thrombocytopenia. The specificity, however, was only 57%, which is less than in published studies of adults. In a number of cases presumed to be non-immune-thrombocytopenia, notably a few patients with leukaemia and bone marrow aplasia, we found increased amounts of platelet surface-bound IgG. The significance of this finding is not clear. An indirect assay measuring platelet-specific IgG in plasma was less sensitive (46%) but highly specific for immune-thrombocytopenia (89%). The measurements of platelet-surface-bound IgG and platelet-specific IgG in plasma are of limited diagnostic value in childhood thrombocytopenia but are useful in following the treatment in chronic ITP.

The effect of preparation for lumbar puncture on children undergoing chemotherapy
- 1993

Tidskriftsartikel (refereegranskat)abstract
- At the University Hospital in Lund, Sweden, a preparation program was developed for children undergoing lumbar punctures (LPs) during chemotherapy for leukemia or lymphoma. Subsequently, a study was initiated to determine whether a preparation program for children prior to treatment would reduce their anxiety and improve their cooperation. This study also was undertaken to examine whether reinforcing the preparation information prior to each LP would be beneficial. The 30 children who participated in the study were divided into three groups: a control group whose members did not receive preparation and two other groups whose members were exposed to different numbers of preparation programs. The parents and the nurse in charge evaluated the children's reactions during treatment using two 6-point rating scales: an anxiety scale and a noncooperation behavior scale. Two unbiased, trained observers later viewed video recordings of the children's reactions and evaluated them using the same tools. In addition, each child rated his or her experience of pain on a 10 cm visual analogue scale. Based on these ratings, the groups were analyzed to determine if within-group differences existed from one treatment to the next and to determine if between-group differences existed at the various times of treatment. Few statistically significant differences were found, but the results indicate that the children in the most informed group exhibited sustained reductions in their perceptions of pain. This may signify that reinforcing the preparation information before each of the LPs enabled these children to cope with the pain more effectively.

Bone marrow karyotypes in 94 children with acute leukemia

Tidskriftsartikel (refereegranskat)abstract
- During the last 10 years, we have cytogenetically analyzed at diagnosis bone marrow cells from a total of 94 children with acute leukemia. Of the 78 children with acute lymphatic leukemia (ALL), 53 (68%) had clonal acquired chromosome abnormalities; in the group with acute nonlymphatic leukemia (ANLL), the corresponding proportion was 13 out of 16 (81%). Among the cytogenetically abnormal ALL patients, the most numerous subset was the hyperdiploid cases with stemlines containing 51 or more chromosomes (26 of 53 abnormal cases; 49%). This is a clearly higher proportion than has been reported in large series from other centers. Deletions of 6q were present in 8 cases and rearrangements of 12p in 5. Of the 7 T-cell ALLs, 3 had translocations of the distal part of 7q, i.e., of the region where the beta T-cell receptor is encoded. Only 2 of 26 (8%) patients with leukemic stemlines with more than 50 chromosomes have relapsed; the remainder are still in first remission (mean observation time 42 months). This may be contrasted with 6 of 25 (24%) relapses among the cytogenetically normal (observation time 41 months), and 8 of 27 (30%) relapses among ALL patients with aberrations but with less than 51 chromosomes (observation time 26 months). Our results support the conclusion that the finding of a markedly hyperdiploid leukemia karyotype is indicative of good prognosis in ALL.
