A patient with acute lymphocytic leukemia is described who developed meningeal leukemia 14 months after the initial diagnosis was made. As part of his antileukemic therapy, at that time, he received prednisone and vincristine, given prophylactically to maintain a bone marrow remission. He inadvertently received 15 mg of vincristine instead of 1.5 mg. Following this overdosage he developed pancytopaenia, mild neurotoxicity and subsequently a grand mal seizure associated with the delayed onset of hyponatremia. This was presumed to be due to the inappropriate secretion of antidiuretic hormone (ADH) secondary to vincristine toxicity. This responded to fluid restriction and anti-epileptiform therapy.

Thirteen leukemic patients with disease refractory to conventional chemotherapy were treated with 1.0 to 7.5 g/m2 of Cytosine Arabinoside (Ara-C) over 29 drug cycles. Drug infusions were spaced at 12-hour intervals; a maximum of four doses was administered over 36 hours. After single dose tolerance had been established, three or four dose cycles were given at 2- to 30-day intervals. There were three partial remissions (PR) and one complete remission (CR) in a treatment group of four patients with AML, five with ALL, two with lymphoma converted to leukemic phase, one CML in blast crisis, and one promyelocytic leukemia. Five of the patients were septic and considered terminally ill at the time of treatment. All other patients had evidence of drug responsiveness. The nadir of the white count occurred from 3 to 12 days after treatment, with subsequent recovery of the peripheral granulocyte count between days 12 and 28. Toxicity included nausea and vomiting (GI symptoms) in twelve patients, central nervous system (CNS) disturbances in eight patients, one episode of inappropriate antidiuretic hormone syndromes (SIADH), one of hyperuricemia, and fever in eleven patients. There was no evidence of hepatic or renal dysfunction. These high doses of Ara-C appear useful for treatment of patients with refractory leukemia. Hospitalization is brief and toxicity acceptable.

Five patients with an unusual encephalopathy, possible secondary to measles virus infection, are described. Features common to these patients are: an existing chronic disease, neurologic deterioration 2 1/2 to 6 months after a measles infection, and death several weeks later. These events occurred when the chronic disease (e.g. leukemia or neuroblastoma) was in remission. That the measles virus was the causative agent is suggested only by finding in brain and extracranial tissues intracytoplasmic and intranuclear inclusions which contained measleslike particles. Additional clinical features seen in each of the five patients were: seizures, hypertension, and the inappropriate secretion of antidiuretic hormone.

Sodium vanadate (11 microM) amplified the PGI2 production of rat liver cells (the C-9 cell line) incubated with thrombin, platelet activating factor, lysine-vasopressin, the Ca2(+)-ionophore A-23187, interleukin-1 beta, 12-tetradecanoylphorbol-13-acetate, teleocidin, epidermal growth factor, palytoxin, thapsigargin and colchicine but not that stimulated by exogenous arachidonic acid. Sodium vanadate (2.2 microM) also amplified PGF2 alpha production of dog kidney cells (the MDCK cell line) incubated with norepinephrine and, at 0.4 microM, PGI2 production of bovine aorta smooth muscle cells stimulated by serotonin. Sodium vanadate (55 microM) did not affect production of PGE2 and PGF2 alpha in rat basophil leukemia cells (the RBL-1 cell line) stimulated by the Ca2(+)-ionophore A-23187, but did inhibit synthesis of peptide-containing leukotrienes and 12-hydroxyeicosatetraenoic acid. When used with cultured cells at micromolar concentrations, vanadate is known to inhibit protein tyrosine-phosphate phosphatases. These results suggest that in some cells deesterification of lipids is positively regulated, at least in part, by phosphorylation of tyrosine whereas in leukocytes, lipoxygenase activities are negatively regulated, at least in part, by phosphorylation of tyrosine.

Computerized Chou-Fasman analysis of the secondary structure of human T-cell leukemia viruses (HTLV-I, HTLV-II) and human immunodeficiency virus (HIV) envelope proteins revealed that only one antigenic epitope (amino acids EAL) is shared by the three viruses. A similar antigenic epitope is also found in human and rat brain hormone vasopressin-neurophysin. If autoantibodies in multiple sclerosis (MS) are made to the epitope EAL, they may cross-react with the envelope proteins of HTVL. It is speculated that in AIDS patients, antibodies to the antigenic epitope EAL of HIV may cross-react with brain vasopressin-neurophysin, leading to a decline in this brain peptide hormone. Thus it is hypothesized that treatment of both MS and AIDS patients with a synthetic polymer containing the amino acids EAL might eliminate the antibodies to vasopressin-neurophysin and thus alleviate some of the clinical symptoms.

The syndrome of inappropriate secretion of antidiuretic hormone is a rare but well-recognized neurotoxic side effect of vincristine therapy. The first neuropathological report of a case is presented. A 6-month-old boy with skin leukemia developed inappropriate secretion of antidiuretic hormone caused by vincristine. Postmortem examination revealed axonal spheroids in the ansa lenticularis and the area surrounded by the substantia innominata, amygdala and supraoptic nucleus. The lesion was confined to that area and the neurosecretory neurons were intact with well preserved neurophysin. The pathological findings suggest that these fibers play a role in the development of inappropriate secretion of antidiuretic hormone caused by vincristine therapy.

A female patient, aged 44, with diabetes insipidus as a complication of acute myelomonocytic leukaemia (AMML) is described. She presented with bleeding, anaemia, polyuria and polydypsia. She was treated with intranasal vasopressin for diabetes insipidus and responded well to treatment. Chemotherapy was administered for the leukaemia and a full remission was achieved. The patient relapsed a few days before final admission to hospital and died of septicaemia 7 months after initial diagnosis. A short review of the literature related to this subject is also presented.

The operative management of stress ulcer in children is controversial. Between the years 1969 and 1981, ten children were operated on at the Babies Hospital for stress ulcer. Their illnesses included connective tissue disorders (3), sepsis (2), Reye's syndrome (1), hemolytic uremic syndrome (1), leukemia (1), closed head injury (1), and renal failure (1). In those with bleeding (8), aggressive conventional medical management was attempted prior to operation. Four children also received intravenous cimetidine. Four patients underwent embolization of a feeding artery and/or selective vasopressin infusion. In those patients who perforated (2), operation was performed after a brief period of resuscitation. Ten patients underwent 11 operations. In those who bled, multiple ulcerations were the most common finding. Operative procedures consisted of partial gastrectomy and vagotomy (4), partial gastrectomy alone (2), and vagotomy and pyloroplasty (2). One child who underwent vagotomy and pyloroplasty required partial gastrectomy for recurrent bleeding. Of the two children who perforated, one was managed by plication and the other by partial gastrectomy. There were two deaths (20%), both occurring in patients who had undergone gastrectomy. One survivor has mild dumping. This experience suggests that in children (1) stress ulcers are commonly multiple when associated with major medical illnesses; (2) partial gastrectomy with or without vagotomy affords maximum protection against recurrent bleeding; (3) lesser procedures are effective for solitary bleeding duodenal ulcers or perforation; and (4) selective arterial embolization or vasopressin infusion are unreliable methods for controlling bleeding.

We describe a patient who, at the onset of acute myelomonocytic leukemia, presented with marked polyuria, polydipsia and laboratory findings consistent with diabetes insipidus (DI). He was treated with vasopressin (DDAVP) with a good response and concurrently induced with daunorubicin and conventional doses of cytosine arabinoside. CR was achieved. The vasopressin requirement decreased progressively, but the patient remained DDAVP-dependent after consolidation treatment. He underwent allogeneic BMT, conditioned with busulfan and cyclophosphamide. By day 15 after BMT vasopressin was no longer required and at a follow-up of 9 months the patient has no evidence of DI. In the absence of specific findings, we think it possible that he had leukemic microinfiltration of the hypothalamic-pituitary area. The drugs used for conditioning may have eradicated CNS disease.

We report a case of AML with diabetes insipidus (DI). A 68-year-old female was admitted to our hospital because of fever and leukocytosis. The WBC was 197,000/microliter with 98% blasts positive for myeloperoxidase, CD33, CD34 and HLA-DR. While, on admission, urine volume was more than 6 liters daily. Blood vasopressin level was 0.3 microgram/ml. The patient was diagnosed as having AML with DI. By chemotherapy consisting of BHAC, DNR, 6-MP and PSL and intrathecal administration of AraC, MTX and PSL, and nasal drip of DDAVP, complete remission was attained and the urine volume was reduced to normal. Finally DDAVP became unnecessary. Although the exact cause of DI cannot be ascertained, rapid increase of leukemic blasts and leukostasis in small vessels might be associated with hypothalamus-pituitary system damage. Reportedly, DI is a rare complication of leukemia and administration of DDAVP could be halted in only two patients with leukemia and DI.
