Microleakage in class II composite restorations bonded to dentin using thermal and load cycling.

The effectiveness of a dentin-bonding agent (DBA) and a glass-ionomer cement liner (GIC) in reducing the marginal microleakage at the cervical margin of Class II posterior composite restorations was examined. The effect of load cycling on microleakage of this type of restoration was evaluated. The Class II cavities were prepared in extracted human pre-molar teeth, with the cervical margins finished approximately 1 mm below the CEJ.

Early congenital syphilis and severe haematological disturbance.

The early clinical signs and symptoms of congenital syphilis are diverse but, if undiagnosed, signs of the disease may subside until the late stigmata appear. We report a case that illustrates that the haematological signs and symptoms may be so severe as to mimic a diagnosis of leukaemia or disseminated malignant disease.

Adult Gaucher disease in association with acute leukaemia.

A non-Jewish patient diagnosed as having Gaucher disease at the age of 67 is described. Fourteen months after presentation he was diagnosed as having acute myeloid leukaemia. A possible association between Gaucher disease and acute myeloid leukaemia is suggested.

A myeloproliferative disease in two infants associated with eosinophilia and chromosome t(1;5) translocation.

Two children are described who presented at the age of 5 and 7 months with anaemia, a high white cell count with eosinophilia and thrombocytopenia. Both children had an identical balanced translocation t(1;5)(q23;q33) and no evidence of a constitutional abnormality. The response to treatment of one child was poor, the other remains well on therapy.

Second malignancies in children treated for non-Hodgkin's lymphoma and T-cell leukaemia with the UKCCSG regimens.

Eight children treated between 1977 and 1983 with the UK Children's Cancer Study Group's non-Hodgkin lymphoma (NHL) and T-cell protocols have developed second malignancies within 7 years of commencing treatment. Five developed acute non-lymphoblastic leukaemia and a sixth died from infection while pancytopenic with a pre-leukaemic marrow. The other malignancies were cerebral astrocytoma and an undifferentiated low grade sarcoma.

Granular acute lymphoblastic leukaemia of childhood: a morphological phenomenon.

Three hundred and twenty consecutive children with lymphoblastic leukaemia (ALL), treated on the Medical Research Council UKALL VIII schedule, had their Romanowsky stained diagnostic marrows reviewed for the presence of azurophil granules in blast cell cytoplasm. Twenty patients (7%) had greater than 5% blasts showing this feature; 19 had the cell phenotype of "common ALL." Male children and those with French-American-British (FAB) L2 morphology predominantly showed this feature.

The use of a panel of monoclonal antibodies in pediatric oncology.

A panel of monoclonal antibodies including antibodies against neuroectodermal antigens, (UJ13A, UJ127.11, UJ181.4), leukocytes (2D1), intermediate filament antigens cytokeratin (LE61), Vimentin, Desmin (Labsystems, Helsinki, Finland), myoglobin, and neurofilament (155) antigens were assessed for their use as an adjunct to light microscopy in pediatric pathology, with particular emphasis on the "small round cell" tumors.

Idiopathic thrombocytopenia in childhood. Edinburgh experience 1962-82.

This retrospective review of 136 children with idiopathic thrombocytopenia assesses the prognostic significance of various presenting parameters and the effect of therapy. Initial haemoglobin, white cell count, actual platelet count, splenomegaly, hepatomegaly and lymphadenopathy had no significant effect upon the final outcome. Cases of acute I.
