Knowledge and use of evidence-based nutrition: a survey of paediatric dietitians.
OBJECTIVE: To survey paediatric dietitians' knowledge and use of evidence-based nutrition (EBN). DESIGN: Cross-sectional survey using reply-paid questionnaires. SUBJECTS: Paediatric dietitians in Australian teaching hospitals. MAIN OUTCOME MEASURES: Age, sex, appointment, clinical practice, research activities; attitudes to, training in and use of EBN; and perceived barriers to use of EBN. STATISTICAL ANALYSIS: Data were analysed using descriptive statistics (SPSS). RESULTS: Fifty-nine (86%) of 69 questionnaires were returned. Most (97%) dietitians were women working full-time (63%), mean age 37 years (+/-9 SD). Most (75%) dietitians encountered knowledge gaps less than five times per week and most (87%) questions related to therapy. The majority (95%) performed their own literature searches, less than five times per month. All had access to >or=1 electronic literature databases including Medline (n = 58, 98%), Cochrane Library (n = 44, 75%) and CINAHL (n = 35, 59%). Information sources used most often were Medline and consultation with colleagues. Reported barriers to using EBN were lack of time (n = 53, 90%) or lack of skills for critical appraisal of published articles (n = 51, 86%) or literature searching (n = 48, 81%). While 53 (90%) believed in an evidence-based approach, 43 (73%) either did not practise EBN or rated themselves as beginners. CONCLUSION: Most dietitians favoured evidence-based practice, but reported lack of time, skills or rapid access to electronic databases as barriers to its practice.

Patient knowledge and interest on dialysis efficiency: a survey.
BACKGROUND: Therapeutic compliance is fundamental on dialysis; however following a therapy requires a prior understanding of it. Aim of the study was to assess the need and interest for information on dialysis efficiency and to prepare a dedicated teaching tool. METHODS: 72 patients, on hemodialysis in two limited-care satellite units, were given a questionnaire testing knowledge and interest on dialysis efficiency. In a subsequent second phase, following patients' suggestions, a cartoon book was prepared and opinions recorded. RESULTS: 63 patients' returned the questionnaire. 79.4% had basic knowledge on routine blood tests, 30.1% were aware of their specific meaning. All patients asked for further information, preferring books to other media. The book "Kt/V as cartoon" was distributed; 71.2% read it, 93% scored it as good-very good. In the Unit employing flexible dialysis schedules, 22/42 patients increased dialysis time. CONCLUSIONS: Despite insufficient knowledge on dialysis efficiency, patient interest is high. An educational program is feasible and may also give practical results, such as self-increase in dialysis time.

Teaching technology with technology: computer assisted lessons in the medical school the first Italian experience in nephrology and dialysis.
BACKGROUND: Dialysis is often neglected in academic teaching. At the University of Torino, Italy, teaching Nephrology (4th year of Medical School) consists of 21 hours of formal lessons, 10 hours/student of interactive lessons (4/10 dedicated to dialysis) and 10 optional lessons (3 regarding dialysis). Interactive and optional lessons widely employ computer assisted teaching. Aim of the study was to evaluate student satisfaction on this approach. METHODS: Student satisfaction was assessed on 4 sample lessons (166 students), by two short dedicated questionnaires (0-10 scale, open questions). RESULTS: High scores were given to the dialysis lessons (median 8/10). Computer assisted interface (median 8/10, range 6-10) was of help in check of knowledge in real time (86%), enhancing participation (61%); 62% suggest extending this experience to selected courses, 38% to all. CONCLUSIONS: Medical students consider dialysis an important part of the academic teaching of Nephrology; new interfaces may help to enhance student satisfaction.

Extramedullary involvement at relapse in acute promyelocytic leukemia patients treated or not with all-trans retinoic acid: a report by the Gruppo Italiano Malattie Ematologiche dell'Adulto.
PURPOSE: Recent reports of extramedullary disease (EMD) at recurrence in acute promyelocytic leukemia (APL) have raised increasing concern about a possible role of retinoic acid (RA) therapy. PATIENTS AND METHODS: We analyzed the risk of developing EMD localization at relapse in APL patients enrolled onto two consecutive studies of the Gruppo Italiano Malattie Ematologiche dell'Adulto. The studies investigated chemotherapy alone (LAP0389) versus RA plus chemotherapy (AIDA). RESULTS: When all relapse types were taken into account, 94 (51%) of 184 patients and 131 (18%) of 740 patients who attained hematologic remission underwent relapse in the LAP0389 and AIDA studies, respectively (P < .0001). EMD localization was documented in five (5%) of 94 and 16 (12%) of 131 patients (P = .08). Hematologic and/or molecular relapse was diagnosed concomitantly in all but two patients with EMD in the AIDA study. For patients in the LAP0389 and AIDA series, the probability of EMD localization of any type at relapse was 3% and 4.5%, respectively (P = .79), while the probability of CNS involvement was 0.6% and 2% (P = .28). No significant differences were found with regard to mean WBC count and promyelocytic leukemia/retinoic acid receptor-alpha junction type in comparisons of patients with EMD and hematologic relapse. CONCLUSION: APL patients receiving all-trans retinoic acid in addition to chemotherapy have no increased risk of developing EMD at relapse as compared with those treated with chemotherapy alone.

A multicenter, double-blind, placebo-controlled trial comparing piperacillin-tazobactam with and without amikacin as empiric therapy for febrile neutropenia.
In a prospective, multicenter, double-blind, randomized clinical trial, we compared the efficacy of piperacillin-tazobactam (4.5 g 3 times daily intravenously) plus placebo versus piperacillin-tazobactam plus amikacin (7.5 mg/kg twice daily intravenously) for the treatment of 760 febrile, adult patients with cancer with chemotherapy-induced profound (<500 neutrophils/mm3) and prolonged (>10 days) neutropenia. A total of 733 patients were assessable for efficacy of the drug regimens, and an overall successful outcome was reported in 49% (179 of 364) of the patients who received monotherapy, compared with 53% (196 of 369) of patients who received combination therapy (P=.2). Response rates were similar with both regimens, as were incidences of bacteremia and clinically documented and possible infections. In our epidemiological setting, the initial empiric combination therapy was not associated with improved outcomes when compared with initial monotherapy.

Acute myeloid leukemia in patients previously diagnosed with breast cancer: experience of the GIMEMA group.
OBJECTIVE: To evaluate in a multicenter retrospective study, the clinical and laboratory characteristics and the outcome of patients with acute myeloid leukemia (sAML) previously diagnosed with breast cancer (BC) among an adult acute leukemia population. PATIENTS AND METHODS: Between June 1992 and July 1996, 3934 new cases of adults with acute leukemia were recorded in GIMEMA Archive of Adult Acute Leukemia (2964 AML, 901 ALL, 69 acute leukemia expressing both myeloid and lymphoid surface markers). RESULTS: Two hundred patients (5.1%) presented with a history of previous malignancy (21 of them were affected by ALL and 179 by AML). Among sAML, 37 patients (29%) had a previous breast cancer. They consisted of 36 females and 1 male, median age 56 years, range 34-87. The median latency between the 2 malignancies was 54 months (range 5-379). Twenty-seven patients received chemo- and/or radiotherapy for breast cancer (7 only chemotherapy, 6 only radiotherapy, and 14 combined treatment). All patients were surgically treated but in 10 patients surgical debridement was the sole therapy for breast cancer. The drugs most frequently employed were alkylating agents (18 patients), topoisomerase II inhibitors (9 patients), antimetabolites (20 patients) (CMF, CEF and MMM combinations). At onset of sAML the median WBC count was 7.7 x 10(9)/l (0.8-153) and the median platelet count was 33.5 x 10(9)/l (3-305). Considering morphological features, FAB subtypes were 4 M0, 5 M1, 11 M2, 5 M3, 8 M4, 3 M5, and 1 M6. Cytogenetic study was performed on 28 patients and 12 of them presented abnormalities. It is noteworthy that chromosome 5 or 7 abnormalities (typically observed in those patients treated with alkylating agents) were present only in three cases. Thirty-four patients received chemotherapy for sAML, and twenty-five of them achieved a CR (74%), with a median duration of twenty-eight weeks (5-280+). The overall survival was 8 months (1-80+). DISCUSSION: The high number of sAML we observed in patients with a previous breast cancer, may be due to the fact that this malignancy is the most frequent neoplasm in women and by the high probability of cure with a consequent long disease-free survival. Our results suggest that the risk of sAML after recovery from breast cancer is increasing due to the rise in the number of patients cured from breast cancer, and in the future could be a relevant problem for haematologists.

Clinical and biological features of acute myeloid leukaemia occurring as second malignancy: GIMEMA archive of adult acute leukaemia.
Between July 1992 and June 1996, 3934 new cases of acute leukaemia were registered in the Gruppo Italiano Malattie Ematologiche Maligne dell'Adulto (GIMEMA) Archive of Adult Acute Leukaemia. Two hundred cases (5.1%) presented with a history of primary malignancy (PM), 179 of which were acute myeloid leukaemia (AML). The median age of these cases was significantly higher than that of other primitive AML (63 years vs. 57 years; P < 0.001). The number of men was significantly lower than the number of women [74/1544 (4.8%) vs. 105/1420 (7.4%); odds ratio (OR) 0.63, 95% confidence interval (CI) 0.46-0.87; P < 0.002], as was the number of patients aged <65 years [104/1963 (5.3%) vs. 75/1001 (7.5%); OR 0.69, 95% CI 0.50-0.95; P < 0.01]. An increased incidence of cancer was observed among first-degree relatives of patients with AML occurring after a PM (secondary AML; sAML) [66/179 (36.9%) sAML vs. 757/2785 (27.2%) de novo AML, age adjusted; OR 2.62, 95% CI 1.07-6.42; P < 0.005]. Prevalent types of PM were breast cancer, lymphoma and Hodgkin's disease. sAML occurred after a median latency of 52 months (range 2-379). Of the 122 patients who received chemotherapy for sAML, 67 patients (55%) achieved a complete remission (CR), three a partial remission, 15 (12%) died in induction and 37 (30%) were unresponsive. The median duration of CR was 30 weeks (range 4-250). The median overall survival was 7 months (range 1-196). Comparing acute promyelocytic leukaemia with all other French-American-British (FAB) groups, a significant increase in CR achievement was observed [14/18 (77.7%) vs. 53/101 (52.4%), P < 0.046] as well as in median CR duration (55 vs. 24 months, P < 0.02). The analysis of our data suggests that not only previous chemotherapy but also genetic predisposition could play a role in the pathogenesis of sAML.

Aggressive salvage treatment is not appropriate for the majority of elderly patients with acute myeloid leukemia relapsed from first complete remission.
BACKGROUND AND OBJECTIVES: The prognosis of acute myeloid leukemia (AML) in the elderly is still poor because of different reasons, including a high incidence of relapse. The aim of this study was to investigate whether aggressive salvage chemotherapy (CHT) results in an actual survival advantage in elderly patients with relapsed AML, as well as to compare hospitalization and load of supportive treatment between patients receiving aggressive management or only palliation. DESIGN AND METHODS: One hundred and fifty consecutive patients with relapsed AML (median age 66 years) were analyzed. At relapse, 99 (66%) were treated with CHT, and 51 had palliative management. RESULTS: Second complete remission (CR2) was achieved in 36/99 patients (36%) receiving CHT, while no CR was observed in the other group (p<0.001). Induction death rate was 22%, while 41% were resistant to CHT. The median survival from relapse was 4 months for the whole patient population; according to management, it was 5 months and 3 months for CHT and palliation, respectively (p=0.01). As to patients given CHT, a CR1 duration of more than 12 months was the only parameter significantly related to a better clinical outcome (survival from relapse: 8 vs. 4 months, p=0.002; CR2 duration: 11 vs. 5 months, p=0.001, respectively). Finally, patients managed with palliation required less hospitalization and less supportive therapy as compared to the CHT group. INTERPRETATION AND CONCLUSIONS: Aggressive chemotherapy results in an actual survival advantage only for a minority of elderly patients with relapsed AML, i.e. those with CR1 lasting for more than 12 months.

Feasibility of peripheral blood stem cell rescue as intensification in elderly patients with acute myelocytic leukaemia: a pilot study from the Gimema Group. Gruppo Italiano Malattie Ematologiche Maligne Dell'Adulto.
Elderly patients with untreated acute myeloid leukaemia (AML, n = 47) tested the feasibility of out-patient consolidation therapy and post-consolidation treatment (for patients aged < 71 years) with autologous peripheral blood stem cell transplantation (APBSCT). Overall, 13 patients out of 24 (51%) who achieved complete remission (CR) were eligible for further treatment after consolidation. Five patients were primed with granulocyte colony stimulating factor (G-CSF); a suitable number of CD34+ cells were harvested in three patients and were actually autotransplanted. The toxicity of APBSCT was negligible. Psychosocial problems impaired treatment of some patients on an out-patient basis. Resistant disease, toxicity and logistic problems reduced the number of patients to whom this procedure could actually be applied.

CD56 expression is an indicator of poor clinical outcome in patients with acute promyelocytic leukemia treated with simultaneous all-trans-retinoic acid and chemotherapy.
PURPOSE: Preliminary reports suggest that leukemic cell expression of CD56, a neural cell adhesion molecule, is associated with adverse clinical outcome in either acute myeloid leukemia with t(8;21) or acute promyelocytic leukemia (APL). We investigated the prognostic relevance of CD56 in a series of patients with APL who were treated homogeneously with all-trans-retinoic acid (ATRA) and chemotherapy. PATIENTS AND METHODS: Clinicobiologic presenting features and therapeutic results were analyzed in a series of 100 patients with genetically proven APL who were treated, according to the example of the Gruppo Italiano Malattie Ematologiche Maligne dell'Adulto multicenter trial, with ATRA plus idarubicin (AIDA) and for whom data on CD56 expression were available at diagnosis. RESULTS: Fifteen patients (15%) showed expression of CD56 in greater than or equal to 20% blasts at diagnosis and were considered as CD56(+). No differences were found regarding age, sex, WBC and platelet counts, incidence of coagulopathy, hemoglobin and fibrinogen levels, promyelocytic leukemia/retinoic acid receptor (PML/RAR) alpha fusion type, or complete remission (CR) rate in the comparison of the CD56(+) and CD56(-) populations. Conversely, compared with patients who were CD56(-), patients with CD56(+) APL had shorter CR duration (P =.04) and overall survival (P =.002). In the multivariate analysis, CD56 positivity and initial WBC count greater than 10 x 10(9) cells/L retained statistical significance in overall survival (P =.04 and P =.02, respectively). CONCLUSION: The expression of CD56 is significantly associated with inferior CR duration and survival in patients with APL who were treated with modern frontline treatment that included ATRA and simultaneous chemotherapy. Combined with other well-established prognostic factors such as WBC count, CD56 expression at diagnosis might be used to build prognostic scores for risk-adapted therapy in APL.

Education as a clinical tool for self-dialysis.
Therapeutic compliance and patient education are presently considered crucial parts of end-stage renal disease (ESRD) therapy. In the center where Italian home and self-care dialysis treatment started, an education program was designed as multi-step pathway--following patients from chronic renal failure to dialysis and eventual graft--employing lessons, booklets, and books. Each step was validated in various subsets of patients. Lessons involved two hours of informal discussion on the main aspects of ESRD and renal replacement therapy (RRT); booklets were created from tape recordings of the lessons. Patient participation was good, with 28 of 33 patients on charge in the center for 6 months or more taking part in more than one lesson in 1999. In 16 of 16 patients who answered a questionnaire after two lessons, expressed opinion was "good" to "fair." All asked for further material. With regard to books, 500 copies of the book What does dialysis mean? were given out in the region; this book was validated in 22 patients on peritoneal dialysis (PD) and 18 on hemodialysis (HD). It helped patients to accept dialysis in 65% of cases and to comprehend it in 90%. Four thousand copies of the book Stories, containing 18 interviews on transplantation, were printed, and this book was validated in 21 patients on self-care and 35 on hospital dialysis (potential candidates for graft). Of 56 patients, 53 asked for further material; 19 changed their initial opinion (10 choose transplantation, despite initial skepticism; 9 put off transplantation, despite initial acceptance). On a local scale, the program led 12 of 18 new patients, who followed at least part of the program, to choose self-dialysis (PD, home, and self-care dialysis).

Therapy of molecular relapse in acute promyelocytic leukemia.
Fourteen patients with PML/RARalpha-positive acute promyelocytic leukemia (APL) were given salvage therapy at the time of first molecular relapse. All patients had achieved first molecular remission after the AIDA protocol (all-trans retinoic acid [ATRA] + idarubicin) and were being prospectively monitored by reverse transcriptase-polymerase chain reaction (RT-PCR). Molecular relapse was defined as reappearance of RT-PCR-positivity for the PML/RARalpha fusion (sensitivity 10(-4)) in 2 successive marrow samples collected during postconsolidation monitoring. The median duration of first molecular remission was 7.5 months (range, 2 to 25). Salvage therapy consisted of oral ATRA for 30 days followed by 4 daily courses of chemotherapy (CHT) with cytarabine 1 g/m(2)/d and mitoxantrone 6 mg/m(2)/d. Second molecular remission was obtained in 12 of 14 patients (86%). Seven of these 12 attained molecular remission after ATRA alone. Of the 2 patients who persisted PCR(+) after CHT, 1 died in remission and 1 progressed to hematologic relapse. Of 12 patients PCR(-), 8 received consolidation with autologous bone marrow transplantation (ABMT), and 4 received ATRA-containing maintenance. Ten patients in this group are in sustained second molecular remission at a median time of 9.5+ months (range, 4 to 22+) and 2 underwent hematologic relapse 6 and 13 months, respectively, after transient second molecular remission. The 2-year Kaplan and Meier survival estimate from time of relapse was 92% (95% confidence interval [CI]: 61% to 98%) in this series, and 44% (95% CI: 35% to 52%) in a previous series of 37 patients who received the same treatment at the time of hematologic recurrence (P <.05, by log-rank test). This study suggests that early administration of salvage therapy is advantageous in APL and represents the first experience on therapy of molecular relapse in acute leukemia.

Acute lymphoblastic leukaemia occurring as second malignancy: report of the GIMEMA archive of adult acute leukaemia. Gruppo Italiano Malattie Ematologiche Maligne dell'Adulto.
Between July 1992 and June 1996, 901 new cases of adult acute lymphoblastic leukaemia were recorded in the GIMEMA Archive of Adult Acute Leukaemia; 21 of them (2.3%) had a previous primary malignancy (PM). We found that secondary acute lymphoblastic leukaemia cases (sALL) presented with older age, a high incidence of pre-pre-B immunophenotype and a significantly higher prevalence of cancer among relatives compared to de novo ALL. The leukaemogenic activity of the cytotoxic drugs employed for the treatment of PM may have played a potential role in only a proportion of patients, opening the possibility that some sALL patients may have developed two or more malignancies due to individual predisposing factors.

Retrospective study of candidemia in patients with hematological malignancies. Clinical features, risk factors and outcome of 76 episodes.
A retrospective study of 76 episodes of candidemia in 73 patients with underlying hematological malignancy, from 1988 until 1997, has been conducted to evaluate the clinical characteristics and to ascertain the variables related to the onset and the outcome of candidemia. The most frequent malignancy was acute myeloid leukemia (29 episodes). Candidemia developed mainly during aplasia in patients refractory to chemotherapy (42%). In 65 episodes (86%) the patients were neutropenic (ANC <1 x 10(9)/l) before the candidemia diagnosis for a median time of 13 d, and in 53 episodes (70%) at microbiological diagnosis of candidemia ANC was <1 x 10(9)/l. Candida albicans was the most frequently isolated etiologic agent (31 episodes), but C. non-albicans species sustained the majority of candidemia. Seventeen candidemias developed during azoles prophylaxis. One month after the diagnosis of candidemia, 26 patients died. In 19 cases, death was attributable to candidemia. The case-control study demonstrated, at univariate analysis, that the colonization with Candida. spp. (p=0.004), antimycotic prophylaxis (p=0.01), presence of central venous catheter (p=0.01), neutropenia (p=0.002), and the use of glycopeptide (p=0.0001) increased the risk of candidemia. Using multivariate regression analysis only colonization with Candida spp. and the previous therapy with glycopeptide were associated with a significantly increased risk. Acute mortality, expressed by a cumulative probability of survival at 30 d from diagnosis of candidemia, was 0.67 (95% C.I. 0.55-0.77) and was significantly reduced in patients with neutrophils <1 x 10(9)/l when compared to those with neutrophils >1 x 10(9)/l (p at Mantel-Cox=0.029). Overall cumulative probability of survival at 1 yr was 0.38 (95% C.I. 0.27-0.49) and only the treatment with Amfotericin B significantly reduced the risk of death.

Secondary haematological neoplasm after treatment of adult acute lymphoblastic leukemia: analysis of 1170 adult ALL patients enrolled in the GIMEMA trials. Gruppo Italiano Malattie Ematologiche Maligne dell'Adulto.
Between 1983 and 1994 the incidence of secondary haematological neoplasms (SHM) was evaluated in 1170 new cases of ALL enrolled in the GIMEMA trials. Of the 942 patients who achieved complete remission (CR); seven developed a SHM: four AMLs and three NHLs. The median latency from onset of ALL and of secondary haematological neoplasm was 69 months for AML and 61 months for NHL. Three out of four patients with secondary AML were unresponsive to the new chemotherapy and died, whereas the fourth patient achieved a new CR. Among the three NHL cases, two patients are presently alive in CR, whereas the third patient was refractory to chemotherapy and died. The relative risk of haematological malignancy among the GIMEMA trials population, as compared to that of the Italian Cancer Registries, was 15.25-fold higher, and the actuarial estimated cumulative proportion of ALL patients with a secondary haematological neoplasm at 5 and 10 years were 0.59% and 3.63% respectively. The incidence of adult ALL who developed a SHM, although apparently lower than in the paediatric ALL series, was higher when compared to the normal population. The difference between paediatric and adult ALL is probably due to the lack of craniospinal radiotherapy and to the lower doses of epipodoxiphyllotoxins used in adult trials. The higher percentage of childhood ALL with a prolonged event-free survival could result in an increase of secondary neoplasms in these cases, which suggests that secondary haematological neoplasms in adult ALL patients are real, although rare, events.
