Infectious mural endocarditis is uncommon and not well documented. The clinical setting and pathologic features of five patients with Aspergillus mural endocarditis are described.
Leukemia
, carcinoma, renal transplantation, and hepatic failure were the primary diseases. Associated conditions include high-dose corticosteroids, cytotoxic therapy, renal failure, gram-negative sepsis, and endotracheal intubation. All patients received prolonged antibiotic therapy or treatment with three or more antibiotics. All had clinically undetected aspergillosis and severe fungal
pneumonia
. Fungal myocardial abscesses were present in each patient. Aspergillus mural endocarditis developed in more than 40% of patients with cardiac aspergillosis. Endocardial vegetations were contiguous with underlying myocardial infection; yet they may develop initially as a subendocardial focus rather than from a myocardial abscess. Aspergillus mural endocarditis progressed to destroy the mitral valve ring and served as a source of mycotic embolization to vital organs.

In the Tri-State
Leukemia
Survey, the history of diseases in 605 adult male leukemia cases 15 years and older and in 668 adult male population controls was examined. These diseases occurred at least 1 year before leukemia was diagnosed. The data were based on respondents' answers that the disease was diagnosed by a physician; the respondent was either the subject or his spouse. Of 30 diseases studied, 7 showed an excess among the patients with leukemia: infectious hepatitis, eczema, psoriasis, diabetes, arthritis and rheumatism, heart disease, and ankylosing spondylitis. Mumps had a lower reported occurrence among the cases, whereas
pneumonia
was less frequent in acute lymphatic cases than in population controls. Three diseases occurred significantly less in controls than in persons with specific histologic types of leukemia. Our data revealed a more frequent history of herpes zoster (shingles) in chronic lymphatic leukemia, more hives in acute chronic myeloid cases, and meningitis in acute myeloid leukemia. When we only considered the patients' responses, more of them admitted having had acne than did our controls. The remaining diseases--childhood viral diseases, infectious mononucleosis, smallpox, typhoid fever, dysentery, scarlet fever, tuberculosis, asthma, hay fever, and goiter did not occur more frequently in cases than in controls. The findings were consistent with evidence from previous laboratory and clinical studies. The increased occurrence of infectious hepatitis in our case series is consistent with the findings of other studies showing an increased frequency of Australia antigen in patients with hepatitis, leukemia, and Down's syndrome.

A 26-year-old female patient with acute myeloid leukaemia was hospitalized for the second cycle of remission induction chemotherapy. While neutropenic she developed progressive pulmonary infiltrate, with Micrococcus spp. cultured from two consecutive bronchoalveolar lavage fluids, resulting in respiratory insufficiency. The patient died after an unsuccessful cardiopulmonary resuscitation. This report of micrococcal
pneumonia
emphasizes that the pathogenicity of this skin commensal is not limited to infections in tissues surrounding prosthetic devices or indwelling intravenous catheters. Especially in immunocompromised patients, Micrococcus spp. from bronchoalveolar lavage fluids cannot be lightly dismissed as non-pathogenic when
pneumonia
is considered.

Only a minority of all patients with CML can today be treated by allogeneic bone marrow transplantation (BMT) but the probability of cure for such patients is high. The complications of BMT are similar to those that occur following transplant for other diseases, notably GVHD,
pneumonitis
and infections. Of special interest is the demonstration that a graft-versus-leukaemia effect plays a role in the cure of CML. Studies using the polymerase chain reaction to detect minimal residual disease (BCR/ABL transcripts) may prove useful in predicting relapse and optimizing conditioning schedules. It is now important to test whether BMT can be equally successful in older patients (over 50 years) and in those lacking HLA-identical sibling donors. For other patients autografting may offer the possibility of achieving complete cytogenetic remission and perhaps prolonging life.

A phase Ilate/II trial of hyperfractionated (HFX) radiation therapy for non-small-cell carcinoma of the lung (NSCCL) was conducted by the Radiation Therapy Oncology Group (RTOG) between 1983 and 1987. Fractions of 1.2 Gy were administered twice daily with greater than or equal to 4 hours between fractions. Patients were randomized to receive minimum total doses of 60.0, 64.8, and 69.6 Gy. After acceptable risks of acute and late effects were found, 74.4 Gy and 79.2 Gy arms were added, and the lowest total dose arms were closed. No significant differences in the risks of acute or late effects in normal tissues were found among the 848 patients analyzed in the five arms; risks of severe or life-threatening
pneumonitis
were 2.6% for 60.0 to 64.8 Gy, 5.7% for 69.6 to 74.4 Gy, and 8.1% for 79.2 Gy. Among 350 patients who had the same criteria as Cancer and
Leukemia
Group B (CALGB) protocol 84-33 (American Joint Committee on Cancer Staging [AJCCS], 1984, stage III; Karnofsky performance status [KPS] 70 to 100; less than 6% weight loss), there was a dose response for survival: survival with 69.6 Gy (median, 13.0 months; 2 years, 29%) was significantly (P = .02) better than the lower total doses. There were no differences in survival among the three highest total-dose arms. Comparisons with results in similar patients treated with 60 Gy in 30 fractions of 2.0 Gy 5 days per week for 6 weeks suggest benefit from HFX radiation therapy with 69.6 Gy. Improvement in survival with HFX radiation therapy at 69.6 Gy total dose without increase in normal tissue effects, justifies phase III comparison with standard fractionation alone and combined with systemic chemotherapy in this common presentation of NSCCL.

Interferon-alpha (IFN-a) or 2'-deoxycoformycin (pentostatin; DCF) have each been shown to be highly active in hairy-cell leukemia (HCL). In this phase II study of the
Leukemia
Cooperative Group of the European Organization for Research and Treatment of Cancer (EORTC), the efficacy and toxicity of DCF were investigated in patients who were resistant to IFN-a treatment. Resistance was defined as: (1) progressive disease (PD) under IFN-a therapy for more than 2 months; (2) stable disease (SD) after more than 6 months of IFN-a treatment; (3) relapse within 3 months of discontinuing IFN-a; and (4) intolerance to IFN-a because of World Health Organization (WHO) grade 3 or 4 toxicity. DCF was applied at a dosage of 4 mg/m2 weekly x 3, then 4 mg/m2 every other week x 3. Responders were given a maintenance therapy once per month for a maximum of 6 months. At the time of report, 33 patients with resistant disease were evaluable for response and toxicity. Median duration of IFN-a therapy before DCF administration was 14.7 months (range, 1 to 41 months). Complete remissions (CRs) were achieved in 11 patients and partial remissions (PRs) in 15, resulting in a total response rate of 78.8%. Median interval between beginning of DCF therapy to best response was 3.9 months with a range from 2.0 to 7.0 months. Two patients who achieved PR have relapsed 7 and 14 months after cessation of DCF therapy. The median duration of response was over 11.5 months (range, over 3.0 to over 24.0 months). Three patients died within the first 6 weeks of DCF treatment: one of drug-unrelated cardiomyopathy and two of fungal
pneumonia
. The patients with early death (n = 3) and nonresponsive disease (n = 4) received IFN-a treatment for a longer period (median, 18.0 months) than did the 26 responsive patients (median, 10.0 months). Major side effects included nausea, skin rash, and infections and were otherwise mild. Thus, DCF is highly active in patients with HCL resistant to IFN-a.

A majority of ovine lentivirus (OvLv) infections seen on farms develop after long incubation and a slow progression of disease to death but in nature they may also have short latency and cause acute leukoencephalitis and/or acute arthritis and
pneumonia
in young kids or lambs with exceptionally high mortality. Histopathologically, OvLv diseases may be characterized by lymphoid infiltration, lymphoid hyperplasia with germinal centers and plasmocytosis in the lungs and/or in the CNS, joints and udder. Lymphoid hyperplasia in lymph nodes and spleen, as well as lymphoid infiltration in the kidneys, are almost always seen in advanced cases. In some cases, it shows similarities to lymphoproliferative diseases that are considered malignant. Alveolar epithelial hyperplasia in the lungs is generally also seen, especially in older goats with caprine arthritis encephalitis virus (CAEV), and proliferation of these epithelial cells may form acine and papillary structures and in some cases are histopathologically indistinguishable from tumor nodules seen in sheep pulmonary adenomatosis. Because of complexities in the host-lentovirus interaction, cell-associated transmission and extensive antigenic and genomic variation among infecting isolates, control of infection or prevention of spread are problematic by traditional methods and exploration of alternative control strategies employing selection and expansion of animals genetically resistant to OvLv or transgenic for certain viral genes, merits consideration. Interestingly, the pure Awassi sheep breed are susceptible to infection but do not develop the disease, as do European breeds or cross-breeds in Israel, ie they are infected but not diseased. It seems that the local Bedouin black goat breed is resistant to infection of CAEV under natural conditions.(ABSTRACT TRUNCATED AT 250 WORDS)

Based on the activity of fludarabine and doxorubicin in chronic lymphocytic leukemia (CLL), 30 patients received this combination. The median age of these patients was 61 years; median Zubrod performance status was one; median number of prior therapies was three; and median time to treatment was 53 months. Rai stage was 0 for two patients, I/II for 19 patients, and III/IV for nine patients. Prior treatment included fludarabine in 25 patients. In this regimen, fludarabine was administered as 30 mg/m2/d IV x 3 to 10 patients, 25 mg/m2/d IV x 4 to three patients, and to 17 patients as 30 mg/m2/d IV x 4. A 50 mg/m2 IV dose of doxorubicin was given to all patients. The first 17 patients received prednisone 30 mg/m2 x 5 days; however, this was discontinued due to other data demonstrating no therapeutic advantage and increased opportunistic infections when corticosteroids were added to fludarabine. Toxicity consisted primarily of infectious episodes:
pneumonia
nine, bacteremia one, FUO seven, and minor infection five. Two deaths from
pneumonia
occurred. Standard guidelines for response were used with the addition of a nodular CR group. Despite prior treatment with fludarabine in the majority of patients, the response rate in the 29 evaluable patients was CR 3%, nodular CR 17%, PR 35%, fail 38% and early death 7%. This combination of fludarabine and doxorubicin is active against CLL and warrants further study.

The encouraging therapeutic results attained with the purine analogue CdA in patients with previously treated CLL prompted us to assess its potential in untreated CLL patients. Nineteen patients, 13 males and six females, median age 65 years (range 27-75), with previously untreated CLL were given monthly courses of CdA, 0.12 mg/kg/day as 2-h i.v. infusions for 5 days, until maximum response or excessive toxicity. Five patients with Binet's stage A, 10 with stage B and four with stage C CLL entered the study. After a median of five courses of CdA (range 1-9) nine complete responses (CR = 47%, CI: 24-69%), five partial responses (PR = 26%, CI: 7-46%) and five failures (= 26%, CI: 7-46%) were recorded. In five complete responders and in one partial responder cytofluorometric analysis of blood and/or bone marrow failed to demonstrate a residual clonal B cell population. A search for residual disease by PCR technology and by immunostaining of bone marrow biopsies however disclosed residual leukemic cells in these six cases. Adverse reactions included fever of unknown origin (n = 3),
pneumonia
(n = 2), herpes simplex infection, herpes zoster, an anal abscess, a cutaneous rash, autoimmune hemolysis and mental disturbance (one patient each). In this small cohort, neither age, stage, blood counts, cytogenetics or pattern of bone marrow infiltration at inclusion were predictive for response. From these preliminary data, we conclude that CdA has remarkable short-term efficacy in patients with previously untreated CLL. However, toxicity is not negligible and long-term benefit from therapy with CdA still has to be established.
