Acute pancreatitis in association with L-asparaginase therapy: report of one case.

L-asparaginase has been used clinically for treatment of a wide variety of pediatric neoplastic diseases (e.g. acute lymphocytic leukemia, malignant lymphoma, etc.) A 14-year-old female patient, is a victim of acute lymphocytic leukemia, Pre T type. She got acute pancreatitis after the L-asparaginase therapy. We reported her clinical course and our management. It is concluded that early diagnosis of pancreatitis is usually difficult, because the symptoms are vague, physical findings may be minimal, and laboratory studies are frequently inconclusive until the injury is severe. Therefore, physicians must be cautious to the patient's chief complaint before administering the next dose of L-asparaginase, because it may occur more earlier than the laboratory or image studies and thus could be used to predict pancreatitis.

Non-Hodgkin's lymphoma in childhood--five years survey in VGH-Taipei.

From January 1981 to January 1986, 34 children between 2 and 14 years of age were diagnosed as non-Hodgkin's lymphoma by the Rapport's classification at the Department of Pediatrics of Veterans General Hospital, Taipei, R.O.C. These patients were retrospectively analysed. There was male predominance with a male to female ratio of 2.4:1. The most common symptom was the palpable mass (29 cases, 85.3%) involved the neck and abdomen equally. All the cases were diffuse patterns, DUL (diffuse undifferentiated lymphoma) and DPDL (diffuse poorly differentiated lymphoma) both were the common subtypes of histological patterns. Twenty-eight cases (82%) were in the advanced stage (stage III and IV). The incidence of BM and CNS involvement was 56% and 29.4%, respectively. CNS involvement demonstrated a higher mortality of 100%. Surgery, radiation, and chemotherapy were mainly used for stage I-II and chemotherapy for stage III-IV. The 3-year survival rate of the whole series was 26.5%, and stage I, II, III, and IV was 100%, 50%, 33%, 9%, respectively. The causes of death were CNS involvement (10 cases, 40%), extensive involvement (7 cases, 28.0%), and sepsis (3 cases, 12.0%). This study shows that NHL in children are usually diffuse rather than follicular in histological patterns, often present a palpable mass involved the cervical or abdominal area, and commonly are widespread and tend to disseminate early.

Transient disappearance of immunologic disorders and remission after intercurrent measles infections in children with chronic idiopathic thrombocytopenic purpura.

In two children with chronic idiopathic thrombocytopenic purpura (ITP) a transient remission of thrombocytopenia was observed after intercurrent measles infection. Both cases were girls who had a long history of thrombocytopenia. During acute measles infection, the delayed hypersensitivity response was suppressed. Total T lymphocytes, T-cell subsets, especially OKT4 cells, the lymphoproliferative response, and interleukin-2 (IL-2) and gamma-interferon production were decreased accompanying normalization of the OKT4/OKT8 ratio. However, OKT4 cells remained at a reasonably low level and the lymphoproliferative response stimulated with pokeweed mitogen was still in the lower normal range. Direct immunofluorescent study demonstrated that the measles antigen was present in the mononuclear cells, especially OKT4 cells. The levels of platelet-associated IgG antibody (PAIgG) and IgG circulating immune complex (CIC) were undetectable. One month later, the OKT4/OKT8 ratio lymphoproliferative response significantly increased, IL-2 and gamma-interferon production increased, and PAIgG and IgG CIC reappeared with the relapse of thrombocytopenia. There was also a significant increase in in vitro IgG production due to the presence of patient OKT8 cells and/or OKT4 cells. However, there was no enhancement in the presence of patient B cells. This suggests that the presence of specific OKT4 helper T cells and a defect in the suppressor function of suppressor OKT8 cells contribute to an overproduction of IgG and the appearance of PAIgG accompanied by thrombocytopenia. The transient remission associated with measles infection is probably related to the effect of the virus on the helper T cells, resulting in a decrease in specific OKT4 helper T cells and normalization of the OKT4/OKT8 ratio, suppression of IL-2 and gamma-interferon production, and platelet-associated IgG production.

The adherence of Staphylococcus aureus, Staphylococcus epidermidis and Escherichia coli on cotton, polyester and their blends.

The adherent behaviour of the Gram-positive Staphylococcus aureus and Staphylococcus epidermidis and the Gram-negative Escherichia coli on cotton, polyester and their blends through contact in aqueous suspensions was studied. Staphylococcus epidermidis was found to adhere to fabrics much more so than Staph. aureus. The adherence of both Staph. epidermidis and Staph. aureus to fabrics increased as the content of polyester fibres in the fabrics increased. The attachment of E. coli to all fabrics was very low and was not affected by the fibre contents. Total numbers of adherent bacteria on cotton and polyester fabrics were related directly to the concentrations of the bacterial suspensions. The extents of adherence, expressed by the percentage of adherent bacteria from the suspension, however, were independent of the concentration. The length of contact with bacteria was also found to affect the adherence of bacteria on fabrics studied.

Treatment results of the TPOG-NHL92 protocols for childhood non-Hodgkin's lymphomas in Taiwan: a report from the Taiwan Pediatric Oncology Group (TPOG)

A nation-wide chemotherapeutic trial for childhood non-Hodgkin's lymphoma (NHL) was conducted by the Taiwan Pediatric Oncology Group (TPOG). Four TPOG-NHL92 protocols based on stage and histology were activated in 1992: TPOG-92LD (treatment duration: 8 months) was used for localized (stages I/II) NHL with any histology, 92LB (2 years), 92SNC (5 months), and 92LC (1 year) for advanced (stages III/IV) lymphoblastic (LB), small non-cleaved cell (SNC), and large cell (LC) lymphoma, respectively. From January 1992 through June 1998, 200 children with newly diagnosed NHL from 13 member hospitals of TPOG were enrolled. There were 140 boys and 60 girls. Their ages at diagnosis ranged from 2.4 months to 18.3 years with a median of 8.2 years. There were 54 (27.3%) patients with LB, 94 (47.5%) with SNC including B-cell acute lymphoblastic leukemia (B-ALL), and 50 (25.2%) with LC. Stages I, II, III, and IV (including B-ALL) of the disease comprised 5%, 10%, 43%, and 42% of cases, respectively. There were 176 patients eligible for evaluation of treatment results. The remission rate of induction was 82.4%, induction failed in 22 (12.5%) patients, and nine patients died during induction. As of August 31, 1999, 26 patients relapsed, six died during remission, one patient developed secondary acute myelomonocytic leukemia, and 105 patients remained in continuous remission with a median remission duration of 49 months. The event-free survival (EFS) at 7 years was 63.5%, 61.5% and 65% for LB, SNC, and LC groups (P = 0.8298). The 7-year EFS for stages I/II, III, and IV of the disease was 73%, 68.9%, and 50.3% (P = 0.0212), respectively. We concluded that following the strategy of stratification of therapy, only disease stages had prognostic significance in this study. More efforts are needed to improve our treatment results.

Germ cell tumor in infancy and childhood: experience at one institute compared to other studies.

To understand the difference in incidence and distribution of germ cell tumor (GCT) between cases seen in this institute and Western studies, 98 cases of GCTs collected from 1979 to 1996 were included 50 with gonadal GCTs, 9 with mediastinal GCTs; 9 with retroperitoneal GCTs, 10 with sacrococcygeal GCTs and 20 with intracranial GCTs; all were analyzed retrospectively by chart review. The incidences of testicular and intracranial GCT in all GCTs were higher in this study, i.e. 26.5%(26/98) and 20.4%(20/98) compared to 7% and 6% of American reports. But the incidence of sacrococcygeal GCT in all GCTs was lower in this study, i.e. 10.2%(10/98) compared to 41% of American reports. The incidences of testicular and ovarian GCT in all GCTs were about the same in this study, i.e. 26.5%(26/98) and 24.5%(24/98) compared to 7% and 29% of American reports; 51%(50/98) of all GCTs were gonadal in this study compared to 36% in the American reports.
