Abstract
This study examines differences between cancer centers (CC) and noncancer centers (NCC) in terms of management procedures and outcomes for three pediatric solid tumors: Wilms' tumor (N = 147), rhabdomyosarcoma (N = 87), and medulloblastoma (N = 76). Data were derived for the period 1970-1979 from the population-based Greater Delaware Valley Pediatric Tumor Registry maintained at the Children's Cancer Research Center, which routinely collects data on all childhood neoplasms that occur in a 31-county region. Management measures reviewed included the degree to which important pretreatment evaluations were performed, types of therapy used, and extent of follow-up examinations conducted. Outcome variables were three-year disease-free survival and frequency of deaths related to complications of therapy. Differences in three-year disease-free survival between CC and NCC were noted for medulloblastoma (52% v 24%) and rhabdomyosarcoma (48% v 10%), but not for Wilms' tumor (79% v 68%). Among medulloblastoma patients, differences were detected in the frequency of pretreatment evaluations and in the therapy used. The principal management contrast found in rhabdomyosarcoma was that multiagent chemotherapy was used less often in NCC. Wilms' tumor patients were evaluated and treated similarly in the community versus the CC, except for some contrasts in the surgical approach and the frequency of follow-up for the detection of late complications.

Abstract
An ELISA for the detection of a Ag/Ab system related to non-A, non-B post-transfusion hepatitis (NANB-PTH) has been developed. A convalescent serum from a patient suffering, 14 month before, of NANB-PTH was used both as capture and detector antibody in a "sandwich" type immunoassay to detect an Ag (Ag-NANB). A "blocking" immunoassay was used, in the same test, to detect the corresponding antibody (Ab-NANB). All patients with NANB-PTH were positive, alternately, for Ag-NANB or Ab-NANB. The Ag was found in the acute phase sera of 3 out of 22 cases of NANB-PTH (13,6%), but in none of 29 acute hepatitis type B,26 acute hepatitis type A,14 NANB sporadic hepatitis, 5 infectious mononucleosis and 8 healthy subjects. 2/3 Ag-NANB positive subjects became chronic carriers of this Ag, whereas the third seroconverted for Ab-NANB after the first two months of their disease. Furthermore, a significant increase of the Ab-NANB titer was observed in the convalescent phase of the disease in 18/20 NANB-PTH. As expected, a relatively high prevalence for Ab-NANB was found in the other groups of patients, suggesting the high diffusion of the agent, but none of these subjects showed a progressive increase of the antibody titer during the course of their disease.

Abstract
A new test principle for the simultaneous detection of total approximate titers and immunoglobulin M antibodies has been developed and applied to the detection of antibody to hepatitis B core antigen. The method is based on the combination of a competition radioimmunoassay, for the determination of total antibody titer, with an indirect enzyme-linked immunosorbent assay for the determination of single class antibodies. The interference of the rheumatoid factor was avoided by including heat-aggregated immunoglobulin G in the dilution buffer. The specificity, sensitivity, and clinical application of the test are discussed. The results presented suggest that the simultaneous detection of total and immunoglobulin M antibody to hepatitis B core antigen might be helpful in the differentiation between previous and recent or ongoing hepatitis B infection, as well as in the differential diagnosis of acute hepatitis, in monitoring viral activity in chronic infections, and in helping to differentiate acute from chronic infections. The test principle appears applicable in the accurate diagnosis of other infectious diseases by a single test on only one serum sample.

Abstract
To evaluate the behaviour of the Theophylline-sensitive T lymphocytes subpopulation some modifications of the standard procedure are proposed. Lymphoprep purified lymphocytes were counted in a Neubauer hemocytometer after Acridine Orange stain, viability was evaluated by Ethidium Bromide counterstain and monocytes contamination was evaluated by the peroxidase stain. Sheep red blood cells were treated with AET, Theophylline was used at 3 mM (final concentration) and the results compared with untreated lymphocytes; the enumeration of the rosetting lymphocytes was facilitated by adding Acridine Orange prior to the resuspension. The modifications described were able to increase the % of rosetting T lymphocytes, to eliminate differences depending by different lots of sheep red blood cells and to decrease differences depending by subjective evaluation of the rosetting T lymphocytes.

Abstract
A capture enzyme immuno assay for the detection in the serum of specific IgA antibodies to HAV is described. A total of 203 sera from patients and controls were tested. IgA anti-HAV were present only in sera from patients with recent hepatitis A. 23 patients were followed prospectively and IgA anti-HAV were at detectable levels for at least six months after the onset. The detection of IgA anti-HAV is proposed as an important test to differentiate hepatitis A with persistent hypertransaminasemia from non-A, non-B patients.

Abstract
The pathogenesis of the hepatic damage in hepatitis is not well understood but an imbalance in immunoregulatory T lymphocytes is probable. We tested the Theophylline-sensitive T lymphocytes in acute and protracted cases of hepatitis A, in hepatitis B and non-A, non-B. A delayed increment of such cells was demonstrated in hepatitis B suggesting a positive role in the recovery from the disease. The results were indicative for a direct action of the HAV and nAnB on the lymphocytes. Theophylline-sensitive lymphocytes were increased in the course of protracted hepatitis A whereas were progressively decreasing in nAnB hepatitis. This behaviour of suppressor cells in nAnB hepatitis may explain the high frequency of evolution in chronic liver disease.

Abstract
Peptichemio (PTC), a multipeptidic complex of m-L-phenyl-alanine mustard, was administered to 39 children with neuroblastoma at relapse. The compound was given in two 5-day cycles at dosages varying from 1.0-1.5 mg/kg/day. We were able to evaluate 29 of the initial 39 children for PTC effect; 21 of them had received PTC as first therapy following diagnosis. Ten patients underwent other chemotherapy for relapse before PTC. Three patients were off therapy when relapse occurred. Subjective improvement was observed in 18 cases (62%). Eleven patients (38%) experienced an objective regression, which was scored as complete response in three cases, partial response in two, mixed response in six. In ten children no significant disease change was observed; the remaining eight had a progression of their disease while receiving PTC. The incidence of responses has been higher in patients off therapy at moment of relapse, and lower in those pretreated for their relapse. Previous administration of PTC did not reduce the chance of response at relapse. Major toxic effects were transient, mostly moderate myelodepression and phlebosclerosis. Allergic reactions, nausea, and vomiting, occurred in a few patients. These data indicate that PTC may exert objective antitumor activity in approximately one-third of neuroblastoma patients at relapse.

Abstract
Circulating immune complexes (CIC) were investigated by the fluid-phase C1q-binding test in serum samples from 131 subjects with various clinical types of HBsAg-positive and HBsAg-negative chronic hepatitis diagnosed on both clinical and laboratory criteria, including liver biopsy; serum samples from 28 asymptomatic HBsAg carriers and 75 healthy controls were also examined. The results of these findings were correlated with the liver damage and the clinical course of the disease. CIC were detected in all categories of chronic hepatitis with a significant prevalence only in patients with liver cirrhosis. No correlation was found between the levels of CIC, the presence of circulating HBsAg, and active inflammation or necrosis in any of the different types of chronic hepatitis. In contrast, a highly significant correlation was found between the prevalence of CIC and a more severe prognosis in patients with CAH and liver cirrhosis. The findings suggest that the presence of CIC is not specific for a given type of chronic liver disease and that they do not play any role in the pathogenesis of liver damage. The correlation observed between the presence of CIC and an unfavourable course of chronic liver disease suggests that CIC may modify the host's immune defence mechanisms.

Abstract
Oral glucose tolerance tests were performed in 47 children with acute lymphoblastic leukemia (ALL), treated according to 2 consecutive protocols. Glucose and insulin values were assessed before and after L-asparaginase (L-asp). 30 children (group A) received L-asp as a single-agent consolidation course, after achieving remission with vincristine (VCR) and prednisone (PDN). Normal insulin and glucose levels were found in all patients before L-asp; 4 children (13%) had a transient impaired glucose tolerance (IGT) after completing L-asp therapy. 17 children (group B) were given L-asp during induction therapy with VCR and PDN, and all achieved complete remission. 5 patients (23%) had IGT, without hypoinsulinemia, before L-asp administration. IGT normalized in 4 patients after L-asp, the other children developed a diabetes mellitus. Only 1 patient, with a normal IGT test before L-asp therapy, showed a transient IGT after L-asp. In patients with ALL, the presence of IGT before treatment may be related to leukemia. The concomitant use of steroids does not influence the incidence of IGT in our series. Our data reveal normal insulinemia in patients with IGT. Thus, the leukemic process itself may play a much more significant role in inducing abnormalities in carbohydrate metabolism.

Abstract
40 children (23 males, 17 females) have been diagnosed have ANLL during the period from february 1970 to september 1981. According to FAB classification, 24 cases were M1,-M2, 9 M3, 3 M4, 3 M5 and 1 M6. At diagnosis, 20 patients (50%) had leukocytes less than 10.000/mmc, 6 (15%) had leukocytes greater than 50.000mmc. Hb levels was 7 g% in 16 patients (40%); 10 children had hepatosplenomegaly (25%), 7 splenomegaly (18%) and 5 lymphoadenomegaly (13%). 4 patients had cutaneous or mucous infiltrates. None had meningeal involvement at diagnosis. According to the year of diagnosis, 3 groups can be identified. In the group I (1970-73), 11 patients have been treated with not codified combination chemotherapy as ARA-C, 6-TG, DNR, CTX, Metil-GAG. In the group II (1974-76) and in the group III (1977-81), the patients (respectively 12 and 17) have been treated according to the following protocols: LAM-5 (3), TRAP (5), COAP (1), LAM 80 (2), AIL 7402 (8), AIL 7604, AIL 7801 (6). Immunotherapy has been performed in 7 cases. CNS prophylaxis (MTX i.t. +/-ARA-C +/- RT) was given in 5 patients of group II and in 6 of group III. I patients of group I (45%), 6 of group II (50%) and 13 of group III (76%) achieved CR. Median duration of remission was 5 months in the group I and in 17 in group II and III.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Soluble (free) and insoluble (IgG-bound) hepatitis B e antigen (HBeAg) activities in 1,33 M ammonium sulfate solution was evaluated serially in sera from 12 patients with acute type B hepatitis followed up to 60 days. In three cases preclinical sera were available. In patients who showed clinical and biochemical resolution of hepatitis within 60 days, HBeAg free was the prevalent form of circulating HBeAg during the incubation period of disease, then gradually shifting to the IgG-bound form at the onset of jaundice. Finally HBeAg-bound was no longer demonstrable, followed by detection of anti-HBe antibody. On the contrary, in all patients with unresolved hepatitis both HBeAg-free and HBeAg-bound were detected with prevalence of HBeAg-free ratio. These data suggest a striking correlation between synthesis of HBeAg and HBV replication and may indicate that HBeAg-free and IgG-bound ratio reflects the stage and prognosis of acute HBV infection.

Abstract
The composition of immune complexes (IC) found in 28 patients with HBsAg positive and negative acute and chronic hepatitis was analysed. Components were defined in PEG-precipitated material isolated by preparative ultracentrifugation on linear sucrose density gradients and analysed by the Ouchterlony plate technique and by the radioimmunoassay of hepatitis B virus markers. Sedimentation rate ranged from 8 to 19s in the serum of patients with chronic hepatitis, whereas heavier IC (greater than 19s) were present in the active phase of the disease. The participation of hepatitis B virus in acute hepatitis was shown by the presence of its antigens. In contrast, a low incidence of vital components was seen in IC of chronic active hepatitis and liver cirrhosis. Thus, other causes must contribute to the formation of IC in chronic liver disease.
