A 42-year-old man was admitted with heavy retrosternal pain lasting 30 min. Electrocardiography showed typical signs of acute anterior myocardial infarction. The patient reported only attacks of coughing for a couple of days, and no serious diseases. The physical examination was normal. Laboratory tests showed a white blood cell count of 45/nl, platelet count of 58/nl, and hemoglobin of 14.4 g/dl. Blood chemistry showed elevated lactic dehydrogenase (413 U/l) but no elevation in creatine phosphokinase or glutamic-oxaloacetic transaminase. Therefore no thrombolysis was administered, but coronary angiography was performed. This showed a long-distance, subtotal thrombotic occlusion of the left anterior descending artery. After percutaneous transluminal coronary angioplasty and implantation of serial stents a normal perfusion of the artery was observed. The patient's blood and bone marrow films revealed acute myeloid leukemia FAB M2. Various conditions can cause a myocardial infarction in leukemias. We discuss the clinical management and the possible reasons for a subtotal thrombotic occlusion of the coronary artery.

The stories of the pain experience of three children with acute leukemia during the first year after diagnosis are presented in this report. To provide a broad picture, children who represent various characteristics were selected: ages 6, 9, and 15 years; two male and one female; two Latino and one Caucasian; two English-speaking and one Spanish; two with acute lymphocytic leukemia and one with acute myelocytic leukemia. Consideration of the disease, procedures, treatment, and normal childhood pain experiences will provide the nurse who cares for these children guidance in knowing why and when pain may occur, which will lead to timely interventions for the pain.

A retrospective survey was conducted over a 10-year period (1990-99) among 52 haematology divisions in order to evaluate the clinical and laboratory characteristics and outcome of patients with proven Pneumocystis carinii pneumonia (PCP) complicating haematological diseases. The study included 55 patients (18 with non-Hodgkin's lymphoma, 10 with acute lymphoblastic leukaemia, eight with acute myeloid leukaemia, five with chronic myeloid leukaemia, four with chronic lymphocytic leukaemia, four with multiple myeloma, three with myelodysplastic syndrome, two with myelofibrosis and one with thalassemia) who developed PCP. Among these, 18 (33%) underwent stem cell transplantation; only two received an oral prophylaxis with trimethroprim/sulphamethoxazole. Twelve patients (22%) developed PCP despite protective isolation in a laminar airflow room. The most frequent symptoms were: fever (86%), dyspnoea (78%), non-productive cough (71%), thoracic pain (14%) and chills (5%); a severe hypoxaemia was present in 39 patients (71%). Chest radiography or computerized tomography showed interstitial infiltrates in 34 patients (62%), alveolar infiltrates in 12 patients (22%), and alveolar-interstitial infiltrates in nine patients (16%). Bronchoalveolar lavage was diagnostic in 47/48 patients, induced sputum in 9/18 patients and lung biopsy in 3/8 patients. The diagnosis was made in two patients at autopsy. All patients except one started a specific treatment (52 patients trimethroprim/sulphamethoxazole, one pentamidine and one dapsone). Sixteen patients (29%) died of PCP within 30 d of diagnosis. Multivariate analysis showed that prolonged steroid treatment (P < 0.006) and a radiological picture of diffuse lung involvement (P < 0.003) were negative diagnostic factors.

Osteoarticular changes may occur in up to 23% of the cases with Acute Lymphoblastic Leukemia (ALL) and even more frequent with Acute Myeloblastic Leukemia (AML). Most of the bone and joint pains are due to neoplastic infiltration, radiologically obvious as metaphyseal clear stripes, parietal enlargement, periosteal reaction, osteolysis and diffuse osteoporosis in the long bone. In Malignant Lymphomas (ML) the bone involvement is rarer, usually bone metastases identifiable with Tc scintigraphy being the cause. In Neuroblastoma (Nbl) cases, bone metastases are commonly associated with abdominal tumor beyond one year of age. Of the total ALL, AML, ML and Nbl cases treated in our Oncology Dept, we selected 43 children with osteoarticular involvement. The sex ratio was 24 boys to 19 girls and the specific malignancy was ALL in 25 cases, AML in 5 cases, ML in 2 cases and Nbl in 10 cases. The following biological parameters were monitored: type of onset, the localization and nature of the bone affectation, differential diagnosis, and the response to therapy. The presence of the osteoarticular involvement has proved to be of no prognostic significance. The spectrum of clinical manifestations varied from mild pain to severe disability, in 7% of the cases being the unique symptoms. The type of lesion did not rise important differential diagnosis issues, excepting the cases with unique osteolytic lesion or diffuse osteoporosis, where the rest of the data and the elevated urine vanilmandelic acid helped to establishing the diagnosis. We conclude that the osteoarticular involvement encountered in different malignancies in children is a major sources of diagnostic problems, but it is not associated with a significant outcome.

A 16-year-old boy with refractory acute myelogenous leukemia developed Fournier's gangrene as an early complication after two-antigen HLA-mismatched unrelated cord blood stem cell transplantation. On day 25 after the transplantation, he noted abrupt onset of penile swelling with miction pain. The penile inflammation rapidly extended posteriorly to involve the scrotum and perianal tissues, inferiorly to involve the thighs, and superiorly up the lower abdominal region within the next 36 h, and he died from sepsis on day 27. Fournier's gangrene presenting as a genitoperineal necrotizing fasciitis should be considered as a potential complication in umbilical-cord blood recipients in the cytopenic post-transplant phase.

Treatment of healthy donors with recombinant human granulocyte colony-stimulating factor (rhG-CSF) allows the mobilization and peripheralization into circulating blood of an adequate number of CD34+ cells that can then be collected by leukapheresis (PBSC). This procedure avoids the invasiveness of bone marrow harvest and the risks related to general anesthesia. The main adverse effects of rhG-CSF are: bone pain, 84%, headache, 54%, fatigue, 31%, and nausea, 13%, which are usually scored by the donors as moderate to severe, resolving within 2-3 days after discontinuation of the cytokine. Analgesics, mainly acetaminophen, are sufficient to control the pain. Less than 5% of the donors experience non-cardiac chest pain, a local reaction at the injection site, insomnia, dizziness or a low-grade fever. Discontinuation of the PBSC procedure because of adverse effects of rhG-CSF or leukapheresis is rarely necessary (0.5%) but this good tolerability can be hampered by the need, in 5-20% of cases, for an adequate venous access that requires insertion of a central or venous catheter. There are no absolute contraindications to the stimulation of healthy donors with rhG-CSF but the description of cases of non-traumatic splenic rupture, iritis, cardiac ischemia, and gouty arthritis suggests that further precautionary restrictions are advisable when deciding eligibility for PBSC collection. The main advantages for patients receiving an allogeneic PBSC transplant are the faster hematologic and immunologic recovery and the potential for a greater efficacy in advanced disease by lowering the transplant-related mortality. One of the major concerns regarding the use of rhG-CSF in unrelated healthy donors is the uncertainty about its possible role in triggering malignancy, in particular myelodysplastic syndrome and acute myeloid leukemia. There are no studies with an adequate sample size and follow-up that can answer this question but two recent retrospective studies reported that in the medium term rhG-CSF is not associated with an excess of lymphoproliferative disorders. Currently, caution on the long-term safety of the use of rhG-CSF in healthy donor is still warranted but the data so far accumulated on allogeneic PBSC transplants are encouraging both as far as concerns the good short-medium tolerability profile of G-CSF-stimulation of the donor and the potential major efficacy in leukemia patients.

To increase the knowledge of the final phase of acute myeloid leukaemia (AML) a retrospective review of the medical and nursing records of 106 adult patients with AML who had died in 1995-1997 was made. A total of 27 patients were treated with curative intent at the time of death and 79 patients were prescribed palliative care. From the documentation, an evaluation of the frequency and severity of bleeding and pain episodes was made during their last week in life, and the occurrence of infection criteria was studied. Notations on bleeding were found in 44%, infection in 71% and pain in 76% of the patients. In 54% of the morphine administration days, no information on the effect of given morphine treatment was registered. To give AML patients in the final phase, the best possible treatment, skills in palliative medicine and palliative care are important.

A 62-year-old man diagnosed with acute myelogenous leukemia which had developed from myelodysplastic syndrome received cytarabine and idarubicine as an induction therapy. The patient developed pneumonia and bacterial sepsis during profound neutropenia. Fever and sepsis improved by using many anti-bacterials and anti-fungals but he became febrile again and complained of severe lumbar pain. 67Ga scintigram showed abnormal uptake in the lumbar vertebra and left sternoclavicular joint, suggesting a diagnosis of discitis and osteomyelitis in the lumbar vertebra and sternoclavicular arthritis. We biopsied the site several times but culture of the biopsy specimen could not isolate any pathogens, and high fever persisted for about 10 months despite administration of various anti-bacterials and anti-fungals. Finally we inserted a catheter into the abscess at the iliopsoas muscle and Scedosporium apiospermum was isolated in the bloody pus obtained from the catheter. Itraconazole and amphotericin B were restarted, and the high fever and lumbar pain improved rapidly. The findings of S. apiospermum infection in this patient emphasizes the importance of being aware of this pathogen in patients with hematologic malignancy during the neutropenic phase.

A 75-year-old man was admitted because of right knee joint pain in December 1999. He had suffered from acute myelocytic leukemia (AML: M0) in November 1994 and achieved the first complete remission (CR) then. His AML relapsed in August 1996, but fortunately he achieved a second CR. Radiographical bone examination revealed osteolytic lesions in his right knee and bone scintigraphy showed uptake in the right knee and the middle part of the left femur. MRI also revealed a low attenuation signal in the left femur. He had no abnormal findings in peripheral blood or bone marrow. Histological examination of the biopsied bone tissue showed a diffuse proliferation of round cells with medium-sized or large nuclei. These cells were histochemistrically negative for myeloperoxidase and naphtol-ASD-chloroacetate esterase, and were also negative for lysozyme, cytokeratin 7, 9, 20, EMA, CEA, CD3, CD79a on immunohistochemistry, but were positive for CD43, CD56. In immunophenotypic analysis of these cells by flow cytometry, CD7, CD13, CD33, CD41, CD56 were revealed to be strongly positive. On the basis of these findings we diagnosed these tumors as granulocytic sarcomas (GS), extramedullary recurrence of AML M7. Although radiation (36Gy) to these tumors brought a temporary relief of the pain, he died of systemic relapse of AML in February 2001. When presented CD7+ AML M0 had been diagnosed, but GS cells were also positive for CD 56 and CD41. Although CD56 had not been examined initially, he might have been had myeloid/NK cell precursor acute leukemia and CD41 might be acquired later in the course of the disease. It is known that AML M0, M7 and myeloid/NK cell precursor acute leukemia have poor prognoses, nevertheless he survived for 6 years. It may be that intensive and repeated chemotherapy for AML can obtain excellent outcome in the elderly cases in good systemic condition and with favourable prognostic factors.

We analyzed the efficacy of splenic irradiation in a population of patients with hematologic diseases. The records of the Radiation Oncology Division, Naval Medical Center San Diego were retrospectively reviewed for all patients treated with splenic irradiation (SI) between January 1, 1990 and March 1, 2001. The charts of 17 patients were identified: 5 patients had chronic myelogenous leukemia, 4 had chronic lymphocytic leukemia, 4 had idiopathic myelofibrosis, 2 had polycythemia vera, and 1 patient each had idiopathic thrombocytopenic purpura and acute myelogenous leukemia. Patient ages ranged from 37 to 88 years. Sixteen of 17 suffered from symptomatic splenomegaly. Twenty-six courses of splenic irradiation were delivered to these 17 patients. Treatment courses generally consisted of two fractions of 50 cGy in the first week, two fractions of 75 cGy the second week, and two fractions of 100 cGy the third week. Blood counts were checked prior to each treatment. Seven of the 17 patients died 1 month or less after SI due to the terminal nature of their disease. Twenty-two of 25 treatment courses for splenomegaly resulted in decreased pain and symptoms. Five patients required two treatment courses for splenomegaly, and one patient required five treatment courses. Three of four patients treated for thrombocytopenia demonstrated improvement, but only one was evaluable for more than 2 weeks due to disease-related mortality. Three of five patients treated for leukocytosis had significant improvement. In general, patients suffered few significant complications from this palliative intervention. Splenic irradiation can effectively palliate symptomatic splenomegaly in patients for whom splenectomy is not an option. Retreatment is possible. Splenic irradiation is less effective in the treatment of thrombocytopenia or leukocytosis.
