The data on 31 patients who fit into the clinical spectrum of subacute myeloid leukemia have been reviewed. The majority of patients were male with a median age of 61 years. The interval from onset of symptoms to actual diagnosis was extremely variable, with a mean of 16 months and a median of six months. Most patients presented with anemia and thrombocytopenia, although the white blood cell count varied from striking leukopenia to marked leukocytosis. Examination of the bone marrow invariably revealed abnormalities of all cell lines with megaloblastoid erythrogenesis and dysplastic megakaryocytopoiesis. Although the white cell line showed prominence of immature forms, there was more maturation than is seen in acute myeloid leukemia. Survival from diagnosis was variable, from less than one month to greater than 68 months, with a median of only six months. Anemia and hepatosplenomegaly were prognosticators of a poor outlook; patients with hepatosplenomegaly in association with either leukocytosis or thrombocytopenia had a particularly poor outlook, with a median survival of only one and a half months. Approximately half the patients received chemotherapy with no demonstrated effect on survival.

A case of polycythemia vera with an inhibitor against factor XII was reported. A 60-year-old female was admitted to Hokkaido University School Hospital because of erythrocytosis and hepatosplenomegaly. The hemoglobin was 22.5 g/dl and white cell count was 9,500/microliters without immature cells. The platelet count was 484,000/microliters. Bone marrow specimens showed marked hypercellularity. Philadelphia chromosome was not found on chromosome analysis. She was diagnosed as polycythemia vera according to the criteria of polycythemia Vera Study Group. Activity of factor XII was found to be decreased on the initial examination, but she had no personal and familial history of bleeding. In order to clarify the cause of decreased activity of factor XII, her plasma was mixed with normal plasma, and then examined PTT using factor XII deficient plasma. Her plasma mixed with equivalent normal plasma did not show the correction of prolonged PTT. It was suggested that an inhibitor of her plasma was included in the IgG fraction using gel chromatography. The patient was treated with phlebotomy and administration of N4-palmitoyl (1- -D-arabinofurasyl) cytosine (derivative of cytosine arabinoside; PLAC) 200 mg/day and Busulfan (1 mg/day). Factor XII was not corrected by phlebotomy, but corrected gradually by administration of PLAC and Busulfan.

A girl with common acute lymphoblastic leukemia associated with t(4;11)(q21;q23) is presented. The physical examination revealed hepatosplenomegaly, and the hematologic analysis showed a high count of white cells. Chemotherapy induced a complete remission (CR), and the patient is still in CR (8 months). At the present time, 43 cases (including ours) of acute leukemia with t(4;11) have been published. This disease more often affects children and women than adult men and is characterized by a high blood white cell count and a short survival. The t(4;11)-associated acute leukemia is a heterogeneous group, including acute undifferentiated leukemia, acute undifferentiated lymphoblastic leukemia, and "common" acute lymphoblastic leukemia.

A case study was made on 56 patients with chronic myeloid leukaemia in Singapore. The most common clinical presentations were abdominal discomfort with swelling and hepatosplenomegaly. The mean haemoglobin, white cell count, and platelet count at presentation were 9.23 g/dl, 217.9 X 10(9)/1 and 418 X 10(9)/1 respectively. Twenty-three of the 56 patients had gone into blast transformation at the time of analysis. The median duration of the chronic phase from the time of diagnosis to the time of blast transformation was 23 months. The median duration of survival after blast transformation was 3 months. The median duration of survival for all patients was 23 months. Busulphan remains the drug of choice for the chronic phase of chronic myeloid leukaemia.

A 4-year-old girl presenting with vomiting, abdominal pain, and renal failure was found to have gross hepatosplenomegaly, a renal mass, and bilateral pleural effusions. A diagnosis of acute lymphoblastic leukaemia (ALL) was suggested by a peripheral white cell count (WCC) of 119,000 x 10(6)mm3, 57% blasts, 22% lymphocytes, and confirmed by bone marrow examination. Lymphocyte surface marker studies at diagnosis enabled classification as a T-ALL, with a significant proportion of the T cells also bearing receptors for the third component of complement (C3). Seventy-two percent of the peripheral blood mononuclear cells reacted with anti-Ia monoclonal antibody (FMC44), and a smaller proportion (25%) carried receptors for the Fc portion of IgG. The T-classification of this ALL was verified at central nervous system (CNS) relapse and at a subsequent nodal relapse. Double-marker studies on cells from the infiltrated lymph node prepared in suspension confirmed the presence of Ia-positive T cells. The Ia marker is usually a useful discriminant between T and non-T cells in normal and ALL cell populations. The case described here highlights the need for a panel of markers to be used in classification of childhood ALL and supports the suggestion that there is a distinct subtype of Ia-positive T-ALL.

AST levels from 11 untreated children with T-ALL were found to be significantly higher than those from 74 children with non-T disease. The enzyme was not related to haemoglobin or bilirubin levels nor to the presence of hepatosplenomegaly in any of the patients. It was correlated with the white cell count, but only in the T-cell group and not the remainder. It was also correlated with a parallel (but lesser) rise in ALT, but again only in the T-cell group. The blast cells themselves contained little or no transaminase activity, so it is probable that T-ALL produces more extramedullary tissue damage than non-T disease.

A 46-year-old man with primary myelofibrosis developed polyarthralgia. Marked hepatosplenomegaly was noted, and hematological examinations revealed a white cell count of 25,600/microliters with 42% promyelocytes and thrombocytopenia. The promyelocytes were positive for CD4 antigen and nonspecific esterase as well as peroxidase. Cytogenetic analysis of circulating mononuclear cells showed the trisomy of No. 22 chromosome in 3 of 5 cells examined. Four months later, the patient became asymptomatic, and hematological picture and hepatosplenomegaly returned to the original level. This is the first report describing the transient promyelocytic expansion in myeloproliferative disorders.

We report an infant with autoimmune neutropenia (AIN), idiopathic thrombocytopenia (ITP), and IgG2/IgA deficiency. The patient was referred to our hospital at 5 months of age because of epistaxis and generalized petechiae. Physical examination revealed moderate hepatosplenomegaly. A complete blood count revealed a platelet count of 2.0 x 10(3) cells/microliters, and a white cell count of 3,600 cells/microliters, with severe neutropenia (less than 1% bands and segmented cells). Neutrophils and platelets adhering to megakaryocytes were decreased in the bone marrow. Tests for serum neutrophil-binding IgG (NB-IgG) and platelet-associated IgG (PA-IgG) were positive. A diagnosis of both AIN and ITP was made and therapy with intact-type gamma-globulin and prednisolone was initiated. Improvement occurred, but was temporary. A lack of serum IgA and IgG2 was noted during the clinical course. The patient has not been susceptible to bacterial infections but has had a severe clinical course with rubella and chickenpox.

A 26-year-old female was admitted because of multiple fractures in lower extremities. While in the hospital, she developed a high fever and generalized skin eruption. Physical examination revealed bilateral cervical lymphadenopathy and mild hepatosplenomegaly. The white cell count was 11,200 with 11% atypical lymphocytes. Serum GOT, GPT, LDH were markedly elevated. Infectious mononucleosis was suspected, but the serological test for EB virus did not show evidence of acute EB virus infection. Anti-HSV, CMV, hepatitis A virus antibody titers also did not show significant change during the coarse. The serological test for HHV-6 only showed increased titer of IgM and IgG antibodies. Rapidly elevated IgG antibody titer was indicative of reactivation of HHV-6. So, she was diagnosed as mononucleosis-like syndrome caused by HHV-6, probably reactivated infection. Her symptoms gradually disappeared during a month.

The detection of neurodegenerative and neurometabolic diseases in children relies on a high index of suspicion as most will present as common paediatric problems such as recurrent vomiting, feeding problem, failure to thrive, sepsis, or developmental delay. Alternatively, children may present with an acute encephalopathy or with a chronic progressive encephalopathy. Clinical clues suggestive of neurometabolic disorders include encephalopathic features such as microcephaly, macrocephaly, developmental regression, developmental arrest, change in sensorium, seizures, hypotonia, hypertonia, abnormal eye signs; also extrapyramidal or cerebellar signs and systemic features like abnormal respiration, hepatosplenomegaly, abnormal hair, liver dysfunction, renal tubular dysfunction, cardiomyopathy, and feeding difficulties or growth problems. Initial screening include tests for acidosis, ketosis, hyperlacticemia, and hyperammonemia. Further investigations should amino acid chromatography, assays of organic acids, specific enzyme assay of white cell or fibroblast culture, and histopatholgy of cell and tissue biopsy (white blood cell, skin, muscle, conjunctiva, bone marrow, liver, rectum, or brain). The correct diagnosis holds implications for targeted therapeutic intervention, genetic counselling, and possibly, prenatal diagnosis.
