Abstract
PURPOSE The aim of this study was to investigate children presenting with malignant pelvic tumors obstructing the upper urinary tract. METHODS Seventeen children with upper urinary tract obstruction by a malignant tumor were reviewed. A nephrostomy tube or Double J (DJ) stent was inserted into each obstructed urinary system and removed after tumor shrinkage and/or hydronephrosis regression. RESULTS There were 9 boys and 8 girls in the study; the mean age and median follow-up were 5.7 years and 2.5 years, respectively. The most common obstructing tumor was rhabdomyosarcoma. Twelve children underwent diversion by nephrostomy tubes and 3 by DJ stents; 2 patients underwent resection of the tumors with ureteroureterostomy. Complications after the insertion of the stents included febrile urinary tract infections (UTI) or pyelonephritis in 4 of the children with DJ stents. In the nephrostomy group, febrile UTI developed in 3 and the tube fell out in 1, and was blocked in another. Of the 17 children, 9 have no evidence of disease, 2 are currently under treatment, and 6 died of cancer. CONCLUSIONS The prognosis of children with malignant pelvic tumor obstructing the upper urinary system justifies urgent and optimal upper tract diversion, enabling chemotherapy to be started immediately.

Abstract
OBJECTIVES To summarize and analyze the experience in CNS involvement (CNSI) in children with sarcomas treated in the above-mentioned institutions. PATIENTS AND METHODS From 1990 to 2001, all medical charts were retrospectively reviewed: 19 sarcoma patients (12 boys and 7 girls) were diagnosed with CNSI (4 osteogenic sarcomas, 11 Ewing sarcomas, 2 rhabdomyosarcomas, 1 alveolar soft part sarcoma and 1 mesenchymal chondrosarcoma). Mean age of all patients at the time of initial diagnosis was 14.9 years (range: 4-24 years), mean age at the time when CNSI was diagnosed was 16.9 years (range: 5.5-27 years). RESULTS The frequency of CNSI among our patients was 6.17%. The following symptoms and signs (sometimes combined) presented: headache (10 patients), nausea and vomiting (6 patients), seizures (11 patients) and focal neurological signs (9 patients). The mean duration of time elapsed since diagnosis of CNSI till death or last follow-up was 5.2 months (SD: +/-5.7 months). Four patients received chemotherapy (CT) alone, 8 CT and radiotherapy (RT), 2 RT alone, 3 supportive treatment only, 1 CT and surgery and 1 surgery alone. Sixteen patients died; there was no significant difference in the duration of survival between those who were treated with RT or surgery (mean +/- SD: 6.77 +/- 6.56 months) and those who received only CT or supportive treatment (mean +/- SD: 2.60 +/- 2.94 months) (p = 0.07). Brain disease was the main cause of death in all but 1 patient who died 4 days after autologous bone marrow transplantation from uncontrolled sepsis. In 16 patients, CNSI was part of a metastatic disease. CONCLUSIONS Among children with sarcoma, CNSI is encountered in 6.17% of cases. More effective therapy has to be developed in order to improve their outcome.

Abstract
We describe a 21-year-old patient who was being followed since the age of 3(1/2) years for Langerhans' cell histiocytosis. Although previously a bright and gifted student, the patient presented at age 16(1/2) with new-onset cerebellar neurologic signs, obsessive-compulsive disorder, and dementia. Findings on magnetic resonance imaging study of the brain were normal, but brain single photon emission computed tomography with technetium 99m ethylene cysteinate dimer showed markedly decreased cerebellar perfusion. This case is unique for the wide extent of the central nervous system involvement in Langerhans' cell histiocytosis, which has not been reported previously. Although obsessive-compulsive disorder has also been associated with several other cerebellar disorders, it is still unknown whether the cerebellum plays a role in its development. We suggest that in some cases, brain single photon emission computed tomography may be superior to magnetic resonance imaging for demonstrating cerebellar disorder in Langerhans' cell histiocytosis.

Abstract
BACKGROUND Growth retardation in childhood was only recently recognized as a prominent feature of Gaucher disease type 1, but there are few data on both the pubertal development and the final outcome of growth and sexual maturation. OBJECTIVE To investigate the natural pattern of growth and puberty in patients with Gaucher disease type 1 and the effect of splenectomy and enzyme replacement therapy. METHODS We retrospectively analyzed growth and puberty in 57 patients with Gaucher disease type 1; 52 were followed since childhood and/or prepuberty and 42 have reached sexual maturity and final height. In the analysis we considered severity of disease, time of splenectomy, and start of enzyme replacement therapy. RESULTS Deceleration of growth at age 3-5 years was observed in 30 of 57 patients followed since early childhood while untreated: height-SDS decreased from -0.34 +/- 0.42 at age 0-3 years to -1.93 +/- 0.95 (P < 0.01) at age 7-10 years and was more pronounced with severe disease. A high prevalence (59.6%) of delayed puberty, which was more frequent with severe disease, was observed in 47 patients followed before and throughout puberty. No primary endocrine pathology was found. All patients, untreated as well as treated, with growth and pubertal delay had a spontaneous catch-up, achieved full sexual maturation, and most (83.3%) reached a final height within the range of parental height-standard deviation score. Splenectomy (partial and/or total) performed in 20 patients while still growing had a beneficial effect on growth, which was temporary in some and did not affect puberty. ERT improved growth in 11 patients who started therapy before puberty, as evidenced by a progressive increase in the height-SDS, and seemed to normalize the onset of puberty. CONCLUSIONS Growth retardation in childhood and delay of puberty are characteristic of Gaucher disease type 1 and are more frequent with severe disease. There is a spontaneous catch-up later in life and most patients reach a final height within their genetic growth potential. Enzyme replacement therapy apparently normalizes growth and possibly also the onset of puberty.

Abstract
The objective of the study was to evaluate the lung function of patients with median sternotomy wound complication during the early postmedian sternotomy period and to compare the long-term pulmonary effects of reconstruction using pectoralis major and rectus abdominis muscle flaps. The percentage of predicted, standardized forced vital capacity (FVC); the standardized forced expiratory volume in 1 second (FEV1), and FEV1/FVC ratios of 45 patients with a median sternotomy wound complication were evaluated before and at a mean time of 10.6 months after wound reconstruction. Both mean FVC and FEV1 increased after wound revision compared with the prereconstruction results (8.4% and 9.2% increase, respectively). Patients with painful chest wall movement had the worst (60%) mean FVC and FEV1 before reconstruction when compared with a nonpainful complication. Reconstruction with a muscle flap was followed by an increase of 8.6% and 7.3% in FEV1 and FVC, respectively, from prereconstruction results. However, long-term results indicate that these patients have a mild, restrictive impairment of their lung function tests (LFTs), with about 80% of the predicted FVC and FEV1. Among the muscle flaps, the best improvement and best long-term LFT results were after sternectomy and reconstruction with a pectoralis major muscle flap as compared with a rectus abdominis muscle flap. Sternectomy and reconstruction with a muscle flap is a well-tolerated procedure associated with improvement of lung function compared with prereconstruction values. A pectoralis major muscle flap should be the first choice for muscle flap reconstruction while a rectus abdominis muscle flap should be reserved only for patients with good LFTs before reconstruction.

Abstract
One hundred children with non-central nervous system malignancies received ondansetron at initiation of chemotherapy and every 8 hours for 5 days after cisplatin-containing therapy and for 3 days after other chemotherapy. Ondansetron was administered orally except with the intravenous chemotherapy. For the chemotherapy days, 72 of 93 children (76%) had complete or major control of vomiting on their worst day, 25% with cisplatin-containing protocols, 60% with ifosfamide-containing protocols, and 82% with other protocols. For the overall period, 71 of 93 children (76%) reported complete or major control of vomiting on the worst day, 14% with cisplatin, 60% with ifosfamide, and 83% with other chemotherapy. All had mild or no nausea. Of the 355 chemotherapy days, 228 children (64%) were emesis free, 40% with cisplatin, 60% with ifosfamide, and 68% with other regimens. Of the overall period (541 days), 393 days were emesis free, 45% with cisplatin, 71% with ifosfamide, and 86% with other regimes. Sixty-nine patients were not hospitalized, and oral ondansetron was given when chemotherapy was completed. Of the 241 ambulatory chemotherapy days, 178 (74%) were emesis free. No significant toxicity was encountered. Oral ondansetron reduced hospitalization without reducing antiemetic efficiency in children.

Abstract
Analysis of treatment results in osteogenic sarcoma patients with classical limb primary tumors and without metastasis at diagnosis or major protocol violations showed improved prognosis with a minimum follow-up of over 5.5 years when divided by years of treatment for all event-free survivors. Twelve patients treated in 1980-86 had a 5-year disease-free survival of 67% and 9 treated in 1973-79 had a 5-year disease-free survival of 33% (P = 0.0368). The improvement appeared to reflect the increase in the intensity of the chemotherapy utilized. Definitive surgery, amputation or limb salvage did not affect the outcome. With these surgical approaches the disease-free survival was 67% and 60% respectively.

Abstract
No mention of dactinomycin potentiation of pulmonary radiation was found in a review of the literature of the past 12 years. Before that, this complication was well described and investigators had calculated that dactinomycin increased the toxic effect of lung radiation by a factor of 1.3 and reduced the radiation tolerance of the lung by at least 20%. An example of such a toxic effect is described in the treatment of a 7-year-old girl with lung metastases from Ewing's sarcoma. The chemotherapy protocol followed contained cyclophosphamide, vincristine, dactinomycin, adriamycin, cisplatinum, VP16, and radiotherapy. The treatment was associated with fatal pulmonary fibrosis following the reintroduction of dactinomycin after radiotherapy. Our experience suggests that there is clinical significance to this complication in sarcoma therapy when dactinomycin-containing protocols are used with radiation in the treatment of pulmonary metastases.

Abstract
Clinical features, leukemic cell characterization, chromosomal findings, and treatment outcome were analyzed in a retrospective study of 30 cases with acute leukemia of infancy, 24 infants with acute lymphoblastic leukemia (ALL), and six cases with acute nonlymphoblastic leukemia (ANLL). Extensive bulky disease with organomegaly, central nervous system (CNS), and skin involvement were prominent features at diagnosis with a higher frequency in ANLL as compared to ALL. Four of six ANLL patients were classified as monocytic or myelomonocytic. In the ALL group nine of 24 (36%) were non-L1 morphology and six of 17 (33%) were common ALL antigen (CALLA) negative, the majority of them (five of six) were included in the non-L1 group. Immunophenotyping revealed four cases with early B-cell (three patients: Ia+B4+, and one patient: Ia+) and two cases with T-cell. Mixed lineage leukemia was found in five infants. Heavy chain immunoglobulin gene rearrangement was present in six cases tested, two CALLA+, two with Ia+B4+, and two were undifferentiated mixed lineage leukemia. Chromosomal aberrations were detected in ten of 18 patients, mostly in ANLL and CALLA negative ALL. Translocations were detected in six patients, involving 4q21-23 and 11q23 in three and two cases, respectively. The probability of five-year DFS were 27% for the whole group. The worst prognosis was observed in infants younger than 6 months of age, in whom the leukemia cell characteristics was compatible with stem cell: ANLL, very early pre-B, or undifferentiated mixed type. The chromosomal aberrations found in all cases included translocation with the seemingly nonrandom breakpoints at 4q21 and 11q23, and breakpoints that corresponded to known fragile sites. This finding may be suggestive of an underlying genetic predisposition associated with the poor prognosis of leukemia of infancy.
