RESUMEN
BACKGROUND: The aim of this study was to define clusters of activity in a population-based cohort during the first 5 years after diagnosis in children with ulcerative colitis [UC] and to identify early prognostic risk factors. METHODS: All UC patients from the SIGENP IBD registry with a complete follow-up of at least 5 years were included. Active disease was defined every 6 months in the presence of at least one of the following: clinical activity [Paediatric Ulcerative Colitis Activity Index ≥â 35]; endoscopic activity [Mayo scoreâ ≥â 1]; faecal calprotectinâ >â 250 µg/g; hospitalization; surgery; or treatment escalation. Formula-based clusters were generated based on four published questionnaire-based activity patterns in adults, plus one additional cluster. RESULTS: In total, 226 patients were identified. Forty-two [19%] had moderate-severe chronically active disease, 31 [14%] chronic-intermittent, 75 [33%] quiescent, 54 [24%] active disease in the first 2 years after the diagnosis, then sustained remission, and 24 [11%] a remission in the first 2 years then an active disease. Mild disease onset along with a lower clinical severity not requiring the use of corticosteroids at 6 months were related to a quiescent disease course at the next follow-up (logistic model area under the curve 0.86 [95% confidence interval 0.78-0.94]; positive predictive value 67%; negative predictive value 70%). Eight per cent of patients needed surgery, none in the quiescent group [pâ =â 0.04]. CONCLUSIONS: More than one-third of children with UC present with a chronically active or intermittent course during the first 5 years of follow-up. A significant group of patients has active disease in the first 2 years and then sustained remission. Interestingly, after initial treatment, one-third of patients have well-controlled disease throughout.

The prevalence of celiac disease is still significantly under-estimated world-wide. We compared the Emilia Romagna's with international data. We studied symptomatic patients recorded in reimbursement regional health service program. In year 2008, the patients were 7811. Our investigation did not show age related prevalence, except in the age group 0 to 1 probably due to breastfeeding. The overall prevalence is 1,8 patient/1000 of Emilia Romagna citizens. The prevalence is extremely variable in the different districts from 1:384 Parma's area to 1:909 Piacenza's. Our data confirm the underestimation previously found in other countries. Diagnosis (tests and small bowel histology) are performed, but probably a multidisciplinary effort must be made to promote knowledge and to understand pathogenesis of CD.

PURPOSE: To optimize treatment for children with localized resectable neuroblastoma in 21 Italian institutions using a common protocol based on previous experience. PATIENTS AND METHODS: Between January 1985 and December 1992, 152 children aged 0 to 15 years with nondisseminated neuroblastoma were entered onto this study following complete resection of tumor without tumor rupture (TR) (stage 1), or resection with minimal tumor residue, and/or tumor infiltration of regional lymph nodes (LN+), and/or TR (stage 2). Of 144 assessable children, 69 were classified as having stage 1 disease and 75 as stage 2. Of stage 2 children, 49 had low-risk (LR) characteristics (age, 0 to 11 months or 1 to 15 years but negative lymph nodes and no TR). Stage 1 and stage 2 LR children did not receive adjuvant therapy. The remaining 26 stage 2 children had high-risk (HR) characteristics (age, 1 to 15 years with LN+ and/or TR) and received adjuvant chemotherapy for 6 months. RESULTS: Of 144 children, three died of therapy-related complications and 19 relapsed, of whom six died of disease. The estimated 5-year overall survival (OS) rate was 93% and the event-free survival (EFS) rate was 83%. Of 69 stage 1 children, one died postoperatively and five relapsed (one local and four disseminated, two of whom died), for 94% OS and 90% EFS rates. Of 49 stage 2 LR children, six relapsed (four local and two disseminated); relapses occurred in five of 20 infants with LN+, in one of four infants with TR, and in none of the remaining 25 children. One child died of disease and one of toxicity, for 96% OS and 85% EFS rates. Of 26 stage 2 HR children, eight relapsed (three of 20 with LN+, three of four with TR, and two of two with LN+ and TR), of whom three died of disease and one of toxicity, for 87% OS and 61% EFS rates. CONCLUSION: Our data confirm the overall good prognosis of children with localized resectable neuroblastoma. LN+ and TR predisposed to relapse at all ages, but infants tended to have a less aggressive course after relapse. Stage 1 and 2 LR children had 94% and 96% OS rates, respectively, which justifies a policy of no adjuvant chemotherapy. Eight of 26 children with stage 2 HR relapsed despite 6 months of chemotherapy; for these children, more intensive chemotherapy may be required.

PURPOSE: To report on the treatment of patients with newly diagnosed neuroblastoma presenting with spinal cord compression (SCC). PATIENTS AND METHODS: Of 1,462 children with neuroblastoma registered between 1979 and 1998, 76 (5.2%) presented with signs/symptoms of SCC, including motor deficit in 75 patients (mild in 43, moderate in 22, severe [ie, paraplegia] in 10), pain in 47, sphincteric deficit in 30, and sensory loss in 11. Treatment of SCC consisted of radiotherapy in 11 patients, laminectomy in 32, and chemotherapy in 33. Laminectomy was more frequently performed in cases with favorable disease stages and in those with severe motor deficit, whereas chemotherapy was preferred in patients with advanced disease. RESULTS: Thirty-three patients achieved full neurologic recovery, 14 improved, 22 remained stable, and eight worsened, including three who become paraplegic. None of the 10 patients with grade 3 motor deficit, eight of whom were treated by laminectomy, recovered or improved. In the other 66 patients, the neurologic response to treatment was comparable for the three therapeutic modalities. All 11 patients treated by radiotherapy and 26 of 32 patients treated by laminectomy, but only two of 33 treated by chemotherapy, received additional therapy for SCC. Fifty-four of 76 patients are alive at time of the analysis, with follow-up of 4 to 209 months (median, 139 months). Twenty-six (44%) of 54 survivors have late sequelae, mainly scoliosis and sphincteric deficit. CONCLUSION: Radiotherapy, laminectomy, and chemotherapy showed comparable ability to relieve or improve SCC. However, patients treated with chemotherapy usually did not require additional therapy, whereas patients treated either with radiotherapy or laminectomy commonly did. No patient presenting with (or developing) severe motor deficit recovered or improved. Sequelae were documented in 44% of surviving patients.

A one-year prospective, multicentre surveillance study on aetiology, main clinical features and outcome of bloodstream infections in children with cancer was conducted in 18 paediatric haematology centres belonging to the Italian Association for Paediatric Haematology and Oncology. A total of 191 bloodstream infections were reported during the study period. Of them, 123 (64%) occurred in neutropenic and 68 (36%) in non-neutropenic patients. Gram-positive cocci caused 45% (85/191) of the episodes, gram-negative rods 41% (78/191), and fungi 9% (18/191). The remaining 5% (10/191) of the episodes were poly-microbial infections. A total of 204 pathogens were isolated (46% gram-positive cocci; 44% gram-negative rods; and 10% fungi). The aetiologic distribution was similar among neutropenic and non-neutropenic patients. A correlation between the infection and the presence of an indwelling central venous catheter was found in 20% (23/114) of the episodes among neutropenic patients and in 55% (23/62) among non-neutropenic patients. Gram-negative micro-organisms were isolated in an unusually high proportion of catheter-related infections (48%). The overall mortality rate from any cause within 30 days from the first positive blood culture was 11%, and was higher among patients who were neutropenic at the onset of the infection than among those who were not neutropenic (15 versus 4%, P = 0.03). In addition, the mortality was significantly higher in recipients of bone marrow transplantation than in patients with acute leukaemia or solid tumour (21, 11 and 6%, respectively) and was also higher in fungaemias and poly-microbial infections (22 and 30%) than in single gram-positive and gram-negative bacteraemias (11 and 6%).

Since 1993 pediatric patients affected by high-risk Ewing sarcoma for the presence at onset of a large pelvic mass and/or metastatic disease, were enrolled in a national pilot study comprehensive, finally, of a high-dose chemotherapy (HDCT) procedure with hemopoietic stem cell support. The HDCT procedure considered as consolidation of the disease status obtained after the first-line therapy was followed by the reinfusion of granulokine colony-stimulating factor-primed (G-CSF) peripheral blood progenitor cell (PBPCT). Here we present the results in terms of treatment-related toxicity, hospitalization and rescue of the bone marrow function, in 17 pediatric patients enrolled in such a pilot protocol and submitted to HDCT and PBPCT at the end of first-line therapy.

OBJECTIVE: The aim of this investigation was to evaluate the utility of IGF-I and IGFBP-3 determinations in screening for GH deficiency (GHD) in children previously submitted to treatment for childhood malignancy. PATIENTS AND METHODS: We compared the GH responses to two pharmacological tests (arginine and levo-dopa) with the IGF-I and IGFBP-3 levels in 48 patients (29 boys) who had undergone bone marrow transplantation (BMT) (36 patients) or treatment for a solid cranial tumor (12 patients). RESULTS: 22 patients (45.8%) showed GHD (i.e. GH peak < 8 ng/ml in both tests), and only three (13.6%) of the GHD patients had concomitant low IGF-I levels (i.e. -2 SD below the normal mean) and only one (4.5%) an abnormal IGFBP-3 value (i.e. -2 SD below the normal mean). Among the 26 children with normal GH secretion, 21 (80.8%) also showed normal IGF-I and IGFBP-3 levels, three (11.5%) had a concomitant low IGF-I value and two (7.7%) a concomitant low IGFBP-3 value. A significant correlation was found between GH secretion and age at diagnosis (r = 0.26, P < 0.05), and between IGF-I and IGFBP-3 (r = 0.52, P < 0.0001), but not between GH and IGF-I or IGFBP-3. Comparing the growth pattern of these patients from diagnosis to the first year after therapy or BMT, we found that while individual height changes did not correlate with the GH peak, a significant correlation was found between height SDS decrease and IGF-I (r = 0.31, P < 0.05) or IGFBP-3 SDS (r = 0.37, P < 0.01). CONCLUSION: Our results indicate that the cut-off of -2 SD for IGF-I and IGFBP-3 was insensitive in screening for GHD. A normal value did not exclude a subnormal GH response to provocative tests and therefore although IGF-I and IGFBP-3 levels may be indicators of the growth pattern, they cannot be used alone as a tool for identifying GHD children after treatment for childhood malignancy.

In a group of 22 patients with a stage 4 neuroblastoma, MIBG and 99mTc-MDP scintigraphy and radiological skeletal survey were performed at diagnosis to assess the presence of metastatic skeletal disease. In 20 out of 22 patients the MIBG scan was repeated during follow-up at a time when maximum tumoral regression was expected, i.e. after 3-4 cycles of chemotherapy; scan results were correlated to clinical and laboratory data. At diagnosis MIBG scan showed bone involvement in 19/22 patients, 99mTc-MDP in 20/22 and radiological skeletal survey in 11/22. In 1 patient only marrow aspirate revealed diffusion of disease beyond the primitive lesion. A total of 117/161 (72%) bone lesions were detected by MIBG, 89/161 (55%) by 99mTc-MDP and 47/161 (29%) by radiological skeletal survey. MIBG scintigraphy revealed bone marrow involvement in 11/22 patients in whom either marrow aspirate or bone biopsy were positive. In 5 patients 14 soft tissue lesions were also discovered and all but one primitive lesion accumulated MIBG. Although MIBG scan detected a greater number of bone lesions than 99mTc-MDP, in two patients in whom MIBG scan was negative 99mTc-MDP revealed the presence of bone involvement. Therefore we conclude that 99mTc-MDP scan is necessary to fully assess bone involvement in neuroblastoma at diagnosis. When MIBG scan was repeated after chemotherapy there was a general reduction of the number of detected lesions and in 8/17 patients both bone metastases and marrow involvement could no longer be detected.(ABSTRACT TRUNCATED AT 250 WORDS)
