A 9-year-old boy presented with increasing fatigue, anorexia, weight loss, fever, and absolute eosinophilia (48,000/microL). Pulmonary infiltrates occurred 3 months later. A murmur of mitral regurgitation was heard 5 months after onset of illness, and heart failure soon followed. Despite corticosteroid therapy the eosinophilia persisted intermittently until 1 month before death. The patient died within 9 months of the onset of illness. At necropsy there was cardiomegaly with subendocardial fibrosis in the right and left ventricles. Thrombi were present in the left ventricular apex and behind the posterior mitral leaflet. The findings in 12 previously reported pediatric cases are reviewed. The etiopathogenesis of the hypereosinophilic syndrome is discussed: half of the cases in children are associated with leukemia.

Five acute leukaemia or highly malignant lymphoma patients at a hospital in southern Sweden were interviewed about their daily living problems, their coping strategies and their opinions about the nursing care they received during the active phase of their treatment. In addition the EORTC QLQ-C30, the Global Life Quality and the Sense of Coherence scales were administered. The data were analysed from a hermeneutic phenomenological perspective and interpreted to indicate that the patients sensed a threat to their lives, loss of control, and having to live with uncertainty stemming from the disease and the treatment. They had problems with fatigue, diarrhoea, nausea and vomiting, loss of appetite, sore mouth and high temperature. However, they seemed to minimize the importance of these problems and instead focused on gaining control of the situation, developing their knowledge of the disease and relying on the support of their family. Contradictions appeared in their statements about the quality of care, the information given was said to be good but difficult to understand; although the quality of the nursing care was judged to be high it had to be asked for. That is, help was received on request. The patients' perspective of the family and the nurses should be studied in further research in order to fully understand the patients' coping strategies and how nursing care can support them.

This laboratory previously described an L1210 leukemia cell line (MTXrA) selected for resistance to methotrexate by virtue of impaired transport due to a functional defect in the translocation process. We now report on the sequence analysis of cDNAs encoding the reduced folate carrier from this line and identify a single mutation that results in the substitution of a proline for an alanine in a highly conserved transmembrane region of the protein. Transfection of the parental reduced folate carrier into MTXrA cells resulted in a cell line which exhibited a complete restoration of methotrexate uptake and an enhanced sensitivity to methotrexate. Northern analysis and specific [3H]MTX cell surface binding indicated that expression of the reduced folate carrier was elevated approximately 5-fold in the transfectant compared to parental and MTXrA cells. The MTX influx properties of the transfectant cell line were identical to those of the well characterized reduced folate carrier from parental L1210 cells in terms of: 1) patterns of sensitivity to competing folates, 2) sensitivity to the organic anion sulfobromophthalein, 3) lack of energy dependence, and 4) capacity for trans-stimulation. We also provide new data which suggests that the nucleotide sequence 5' of the predicted ATG initiation codon may encode additional protein information in the form of a leader sequence. Finally, we demonstrate that the MTXrA line has both the mutant and the parental reduced folate carrier alleles but that expression appears to be restricted to the mutant allele. Thus, the methotrexate transport phenotype and resultant drug resistance in this cell line result from genetic/regulatory events at both alleles.

Naturally occurring retroviral infections cause progressive weight loss, immune suppression, invasion by opportunistic organisms, and eventual death. Feline leukemia virus (FeLV) inhibited growth and decreased energy intake in seven experimentally infected weanling cats compared with age- and sex-matched controls. Remarkably, changes in energy intake, energy expenditure, and weight gain occurred in the acute phase of infection prior to the systemic/productive bone marrow phase of FeLV infection. In other words, growth inhibition developed before FeLV infection was clinically detectable with use of standard enzyme-linked immunosorbent assay or fixed-cell immunofluorescence assays of circulating neutrophils and platelets. Acutely infected, previremic cats consumed 25% less energy [Day 4 postinoculation to Day 16 postinoculation (p < 0.05)] and expended 20% less energy [Day 8 postinoculation to Day 18 postinoculation (p < 0.05)] compared with control cats. Growth stunting of inoculated cats began by Day 11 postinoculation (p < 0.05) and was not corrected during the remaining 4 months of the study. Thus, experimental FeLV infection causes perturbations of metabolism and energy balance resulting in permanent growth impairment. Secondly, detrimental metabolic effects begin in the acute phase of retroviral infection, prior to the clinically detectable phase of FeLV infection.

We describe a case of a 15 year old boy who developed acute megakaryoblastic leukemia (AMKL) while receiving treatment with human growth hormone (hGH) for idiopathic growth hormone deficiency (GHD). He was diagnosed as having idiopathic GHD and given hGH from December 1991. The examination of his peripheral blood showed mild pancytopenia 2 months before the start of the hGH therapy. Since January 1992, paleness of the skin, general fatigue and fervescence progressed gradually. In February 1992, because of the occurrence of acute leukemia, administration of hGH was discontinued. Judging from the results of surface marker analysis of the blast cells, the patient was diagnosed as having AMKL. He was treated with chemotherapy for acute non-lymphoblastic leukemia from March 1992. A complete remission was obtained after 4 weeks of treatment. The chemotherapy was completed in July 1993. He remains in complete remission 26 months after diagnosis. This case suggests the importance of hematological examination and, when there is any abnormality which is not caused by GHD, such as pancytopenia, more detailed medical examinations (for example bone marrow examination) are necessary.

All-trans retinoic acid was evaluated in metastatic measurable non-small cell lung cancer. All-trans retinoic acid was given at 175 mg/m2 orally on a daily basis. Twenty-eight patients (median age 58, 16 males, 12 women) had an ECOG performance status of 0 (26 patients) and 1 (two patients). Sixteen of the 28 had no weight loss. Eleven had between 5 and 10% and only one had greater than 10% weight loss at time of entry. Toxicities included cutaneous (cheletis 25/28), fatigue (10/28), myalgias/anthralgias (9/28), and headache (17/28). Alterations in triglycerides and hepatic transaminases were noted in a majority of patients. Two partial responses occurred in patients with adenocarcinoma. Both responses were 7 months in duration. Activity of all-trans retinoic acid in metastatic non-small cell lung cancer is minimal, but due to its low toxicity profile it should be tested in setting with other agents.

Taxol (paclitaxel, Bristol-Myers Squibb Company, Princeton, NJ), a drug extracted from the stem bark of the western yew, shows great promise as an antineoplastic agent for ovarian, breast, nonsmall cell lung, and head and neck cancers; melanoma; and leukemia. Although Taxol first was isolated in 1971, completion of many phase I studies was delayed until 1988, primarily because the drug caused severe hypersensitivity reactions. Other side effects of Taxol include cardiotoxicity, nausea and vomiting, diarrhea, mucositis, myelosuppression, tingling and numbness of the hands and feet, myalgia and arthralgia, alopecia, fatigue, headache, irritation at the injection site, and taste changes. Nursing care includes measures for preventing or minimizing side effects, close assessment and monitoring of potential side effects, patient education, and support. Because of the environmental impact of harvesting the western yew for Taxol, semisynthetic preparations such as taxotere are being explored.

A 57-year-old woman was admitted because of weakness, fatigue, abdominal discomfort, easy bruising and splenomegaly. A highly elevated leukocyte count with hairy-cell-like cells was found, the cells being positive for the monoclonal antibodies CD19, FMC7, CD11c and B-ly-7 and negative for CD24 and CD25. Blood and bone marrow were investigated not only in our own laboratory but also in several other laboratories resulting in a variety of possible diagnoses. Only after combining all data could a definitive diagnosis of variant hairy cell leukaemia be made. The patient was treated initially with a splenectomy and later on with interferon-alpha-2b, resulting in a steady decrease in the leukocyte count. After a follow-up of 2 years a nearly complete remission was obtained with a good quality of life. The differential diagnosis of this rare disorder is discussed with emphasis on the relative contribution of different diagnostic procedures.

A 46-year-old woman with acute promyelocytic leukemia (APL) was treated with all-trans retinoic acid (ATRA) and chemotherapy according to the AML-92, M3 regimen of the Japan Adult Leukemia Study Group (JALSG). Between days 7 and 18 of therapy, she suffered chest discomfort, fever, cough, dyspnea and general fatigue. A chest roentogenogram showed bilateral interstitial infiltrates. Her leukocyte count began to increase rapidly to 6,400/microliters on day 14. Marked hypoxia (PO2 35.9 mmHg) suggested occurrence of retinoic acid (RA) syndrome. She underwent endotracheal intubation and mechanical ventilation with administration of methyl-prednisolone (m-PSL) pulse therapy. Her symptoms promptly abated. Therapy with ATRA was continued and her leukocyte count reached 44,800/microliters on day 19 of therapy. She achieved complete remission on day 48.

Cisplatin, mitomycin C and 5-fluorouracil were given a 55-year-old woman for an unresectable gastric cancer, and successful radical gastrectomy was performed. Postoperative adjuvant immunochemotherapy using UFT and PSK was continued for about 4 years and 4 months. Pancytopenia was observed at 5 years after the treatment and then marked leucocytosis was noted. She also showed complications of general fatigue, appetite loss etc. A secondary acute leukemia associated with eosinophilia was diagnosed by peripheral blood examinations, showing WBC, 122,400: blast, 37.5 % and eosinophil, 41%. Results also showed atypia and pseudo-Pelger nuclear abnormality of eosinophil, high positive stain of cell myelogenic cell surface marker, many numeral and structural abnormalities of chromosomal analysis, etc. From the above results, it was suggested that the leukemia might be induced by previously performed chemotherapy. The patient died about 2 months following its onset.
