A 55-year-old woman had progressive weakness, weight loss, night sweats, fever, right-sided facial weakness, and hepatomegaly. Reticulonodular infiltrates were seen on chest x-ray film and a central filling defect was noted on liver scan. Study of the peripheral blood was noted on liver scan. Study of the peripheral blood revealed pancytopenia and myeloblasts. The bone marrow was not markedly hypercellular but contained noncaseating granulomas and myeloblasts. The patient's condition deteriorated and she died on the 22nd hospital day. Autopsy disclosed disseminated sarcoidosis but no evidence of leukemic infiltrates. Although concomitant "smoldering" acute leukemia cannot be ruled out, the findings in this patient can be best explained on the basis of a myeloblastic leukemoid reaction accompanying sarcoidosis.

On a prospective fashion during approximately two years, 22 pediatric patients with acute non lymphocytic leukemia were evaluated. Of this population the majority had acute mielocytic leukemia, followed by acute myelomonocytic leukemia. Absolutely all patients at the time of diagnosis and subsequently every 4 to 6 weeks had a bone marrow aspiration test. When the patients were first seen, 54% of them presented fever; lymph node enlargement was not a common finding. Only few of this patients presented splenomegaly and/or hepatomegaly. In regards to complete blood counts the most outstanding of its was the presence of leukocyte count above 20000/mm.3 in 8 of this patients. From the 22 patients studied only 21 are evaluable. All 21 patients were treated with a 4 drug combination (modified COAP). Sixteen patients (76%) achieved bone marrow remission, of which only 15 patients (71%) achieved complete remission. The median duration remission was of 9.2 months with a range of 2 to 26 months. At the present time only 7 patients (33%) are alive and on remission. Two more patients are alive but in full relapse. The mortality rate of this study is of 59%. The review of recent chemotherapy reports is presented and the need for further trials is emphasized especially in view of recent papers published in which it appears that better results are being obtained at last in children's acute non lymphocitic leukemia.

Fifty-one adults with acute lymphoblastic leukaemia were entered into a trial of intense initial chemotherapy and early "prophylaxis" of the central nervous system (CNS). Initial treatment with OPAL (Oncovin (vincristine), prednisolone, adriamycin (doxorubicin), and L-asparaginase (colaspase)) followed by craniospinal or cranial irradiation and intrathecal methotrexate produced remission in 36 patients (71%). Seventeen of these patients relapsed three to 18 months after the start of remission; the remainder had been in remission for 12 to 52 months by the end of the study. The predicted median duration of complete remission was 18.5 months. None of the four patients who initially had clinical evidence of CNS disease, three of whom also had leukaemic cells identical to those found in Burkitt's lymphoma, achieved remission. Those patients who initially had hepatomegaly or splenomegaly had a shorter remission than those without. The predicted median survival was 27 months in those who achieved complete remission, one month in those who did not, and 21 months overall. The addition of colaspase and doxorubicin to vincristine and prednisolone and the use of early CNS treatment clearly improved the remission rate among adults with acute lymphoblastic leukaemia, though the presence and length of remission was affected by the extent of disease at presentation. Burkitt-like leukaemia, which had a poor prognosis, is probably a separate disease and may benefit from a different therapeutic approach.

Fifty consecutive patients with blastic chronic myelogenous leukemia were evaluated clinically, morphologically, biochemically, and therapeutically. Forty-five patients had a preceding stable phase (38 Ph'+, 7 Ph'-); five patients presented with de novo Ph+ blast crisis. The most frequent clinical signs of impending blast crisis were weakness, fatigue, increasing splenomegaly, anemia, thrombocytopenia, marrow fibrosis, and a rising neutrophil alkaline phosphatase. Fever (unrelated to infection), skin infiltration, lymphadenopathy, hepatomegaly, thrombocytosis, and basophilia were much less common. The development of aneuploidy occurred in less than one-half of the total group. Myeloblastic morphology at blastic transformation was most frequent with occasional lymphoblastic, promyelocytic, and undifferentiated cases seen. Terminal deoxynucleotidyl transferase was present in one-third of the patients, but had no clear-cut relationship to the morphology. Response to treatment was generally disappointing (two complete and 15 partial remissions in 45 treated patients).

A case of cardiomegalic glycogenosis in a girl of 11 is described. The autopsy revealed cardial hypertrophy, hepatomegaly and enlargement of the kidneys. Histologically, diffuse accumulation of glycogen in the heart muscle, liver, epithelium of the convoluted tubules of the kidneys and in skeletal muscles was demonstrated. The features of the observation include the long-term course of the disease and combination of cardiomegalic glycogenosis with hepato-renal manifestations of enzymopathies.

Four boys, aged 2 years 5 months to 3 years 7 months, with large hepatomegaly due to phosphorylase-kinase deficiency glycogenosis, were given a trial of sodium dextrothyroxine (D-T4) at a mean dose of 0.165 mg/kg/day for an average period of 6 months. Phosphorylase-kinase was undetectable in the haemolysates of erythrocytes (3 patients) or in the liver (one patient) before, and still undetectable in the haemolysates of the four patients during treatment, thus pointing to X-linked phosphorylase-kinase deficiency glycogen storage disease (GSD IXb). D-T4 administration resulted in complete normalization of liver size, decrease of serum GOT (p less than 0.02), GPT (p less than 0.05) and triglycerides (p less than 0.01) to normal values, as well as correction of mild asymptomatic hypoglycemia (p less than 0.01). As long as the outcome of type IXb glycogenosis in adult life remains undefined, dextrothyroxine therapy seems an effective means of reducing liver size and correcting part of the biochemical abnormalities of the disease.

This paper is a progress report of the epidemiologic work carried out under the supervision of the Lombardy Regional Authority during the two years elapsed from the accident in a TCP-producing factory (ICMESA) in Meda (Italy), which resulted in the contamination of several towns of a large, densely populated area called the Brianza di Seveso with a total population of 220,000 inhabitants. A wide follow-up program is in progress in the Seveso area; it includes a clinical screening of the population living in the contaminated area and longitudinal and systematic health control of different groups at risk; a long-term morbidity cohort study has been also undertaken. TCDD exposure following the ICMESA accident resulted in an increased chloracne frequency. Neurologic examinations showed both signs of idiopathic subclinical neurologic damage and cases of clinically detectable idiopathic polyneuropathy in adults. A limited percentage of idiopathic hepatomegaly was reported to be present on clinical investigation; no information, however, is given on the criteria by which the hepatomegaly was investigated. Some alterations were observed in some exposed people in one or more liver tests (mainly transaminases and gamma-GT). So far, immunologic investigations, cytogenetic examination and embryomorphology analysis on cases of therapeutical or spontaneous abortions have not given abnormal results.

Five patients, 4 men and 1 woman, had adult-onset and slowly progressive weakness. There was distal wasting in 2, hepatomegaly in 3, and congestive heart failure in 2. Electromyography showed a mixed pattern with abundant fibrillations. Serum creatine phosphokinase was increased 5- to 45-fold. Blood glucose failed to respond to epinephrine or glucagon, and venous lactate did not rise after ischemic exercise. Muscle biopsy showed vacuolar myopathy affecting both fiber types. By electron microscopy the vacuoles corresponded to large pools of glycogen not limited by a membrane. Glycogen concentration was 3 to 5 times normal in muscle and 7 to 21 times normal in erythrocytes. In the presence of iodine, muscle glycogen showed a spectrum characteristic of phosphorylase-limit-dextrin. Debrancher activity was measured by a spectrophotometric assay and by a radioactive reverse reaction. The activity was lacking in muscle and erythrocytes of 4 patients according to both assays; in 1 patient the reverse reaction was not impaired. Though previously reported in only 5 patients, debrancher deficiency myopathy may not be rare and should be considered in the differential diagnosis of adult-onset hereditary myopathies.

Liver enlargement is frequently reported in studies on the short-term toxicity of chemicals. In many such studies no histological evidence of damage is present but biochemically there is often an increased microsomal enzyme activity (MEA) which is interpreted to represent a type of work hypertrophy. In a few instances, the MEA in the enlarged liver is either normal or less than normal. In such instances histochemical evidence of liver damage (depression of G-6-Pase and autophagy) is found. A compound which produced the latter changes is Ponceau MX. When administered for up to 21 months at a dose-level which produces biochemical and histochemical evidence of liver injury, a series of changes were observed consisting of progerssive diminution of MEA, areas of glycogen accumulation and centrilobular fatty change and these were followed first by nodular hyperplasia and then by frank carcinoma. The protective effect of increased MEA in carcinogenesis was shown by the reduction in tumour incidence on the administration of phenobarbitone simultaneously with acetylaminofluorene, 4-dimethyl aminoazo benzene and diethylnitrosamine. But no such protective effect is seen if the phenobarbitone is administered after treatment with these carcinogens. In fact the number of tumours is enhanced presumably due to preferential stimulation of the growth of malignant cells.

Clinical data and light and electron microscopic findings are presented in a patient with chromic myelomonocytic leukemia of about 5 years' duration and no need for specific therapy. Cytogenetic studies failed to demonstrate a Philadelphia-chromosome. The leading clinical symptoms were anemia, moderate hepatomegaly, and leukocytosis with monocytes in the peripheral blood count. Light microscopy of bone marrow cores showed hypercellularity of neutrophil granulocytic and monocytic cell lines including some precursor forms. Electron microscopy confirmed the existence of a biphasic myelomonocytic cell proliferation with predominance of mature forms in both lineages; there were no gross cellular abnormalities and no "hiatus leukaemicus". Consupicuous were cells of an undeterminated origin apparently neither belonging to the neutrophil granulocytic nor monocytic series and large histiocytic cells, possibly corresponding to the so-called sea-blue histiocytes of light microscopy. The high degree of maturation of both cell lines in the bone marrow is in accordance with the relatively benign and prolongated course of this rare type of leukemia.
