[Prosocial intervention in children and adolescents with autism spectrum disorder without intellectual disability: benefits of videotaping therapy sessions]. / Intervention pro-sociale chez l'enfant et l'adolescent avec trouble du spectre autistique sans déficit intellectuel : intérêt du support vidéo.

INTRODUCTION: The category of pervasive developmental disorders (PDD) without intellectual disability (including Asperger syndrome and high-functioning autism) has increased steadily among individuals since the 1980s. Although some symptoms may decrease with age, functional disability persists and is largely related to abnormalities in social interaction. Within the framework of PDD without intellectual disability, improving social skills appears to be a primary target for intervention programs. Despite a recent increase in the number of studies on this topic, few validated programs are yet available for clinical settings. BACKGROUND: We have developed an intervention targeting the improvement of social skills from the analysis of video sequences. The goal of this intervention is to promote communication within the group through sharing their interests and emotions, and to enhance the understanding of social situations. In order to assess the efficiency of this intervention, we have conducted a prospective, open, and uncontrolled study. First, it aimed at assessing the immediate effect of our intervention on a single social skill (communication) in an experimental situation (in the group) and in an ecological situations (family and school). Second, this study aimed at assessing the effects of this intervention on the subjects' social adjustment. METHOD: This study included 16 individuals with high-functioning autism/Asperger syndrome. Participants were evaluated before and after a 6-month video-based training using measures of socio-communicative and adaptive skills. RESULTS: Results revealed a statistically significant increase in the communication skills not only in the group (15.5%), but also at home (13.7%) and at school (8.7%). The evaluation of socio-adaptive behavior indicates a statistically significant increase in communication (12%), family (7%) and social autonomy (8%), and leisure activities (8%). DISCUSSION: The communication and social adjustment scores obtained upon inclusion were low, despite low autistic intensity scores. However, the improvement at six months was significant for most studied variables. These results are consistent with our clinical findings and seem partly explained by the use of video supports as the mediator of exchanges within the group. However, because of some methodological limitations, the conclusions on the effects of the intervention should be nuanced. CONCLUSIONS: This type of intervention seems to be an interesting therapeutic indication for individuals with high-functioning autism/Asperger syndrome. The first results are encouraging, and all participants enjoyed attending the meetings. These conclusion elements encourage us to continue this intervention and to pursue further research by studying the impact on the individuals' quality of life.

[Anemia and limping in a vegetarian adolescent]. / Anémie et boiterie chez un adolescent végétalien.

UNLABELLED: A vegan diet in the child and adolescent can induce severe bone sequelae by rickets and osteomalacia and megaloblastic anemia by cobalamin deficiency. CASE REPORT: A 15-year-old adolescent was hospitalized because of lameness and pallor. The lameness was explained by femoral epiphysiolysis caused by rickets with severe hypocalcemia. The pallor, jaundice and splenomegalia were due to cobalamin-deficiency megaloblastic anemia. A prolonged supplemental diet with calcium, vitamins D and B12 as well as orthopedic treatment stabilized the bone lesions. The megaloblastic anemia was cured by parenteral cobalamin. The adolescent and his brother were victims of a diet imposed by a cult and a lack of care due to their parents refusing that a vegan diet was the cause of the deficient pathology. Penal proceedings led to the incarceration of the parents and to the placement of the children. COMMENTS: Deficiencies in calcium and vitamins D and B12 may be severe in a child's development with a vegan diet. This case report reveals the social and legal problems of an inappropriate diet in infancy imposed by parents who are followers of a fundamentalist church. Beyond the management of children in cults, health professionals have to prevent, screen and supplement the deficient diet.

Long-term results of CD34(+) cell transplantation in children with neuroblastoma.

BACKGROUND: This is the first report of the long-term results of CD34(+) cell transplantation in children with neuroblastoma. We investigated the hematologic and immune recovery, posttransplant morbidity, and clinical outcome of these children. PROCEDURE: Twenty-three children with advanced neuroblastoma had PBPCs (20 patients) or BM (3 patients) collected, followed by CD34(+) cell selection on Ceprate column. The purge of residual neuroblastoma cells was evaluated using an RT-PCR for tyrosine hydroxylase (TH) mRNA assay. Reinfusion of CD34(+) cells followed busulfan + melphalan myeloablative chemotherapy. RESULTS: A median of 2.9 x 10(6) CD34(+) cells/kg was reinjected. Median days to achieve ANC > 0.5 x 10(9)/liter and platelets > 50 x 10(9)/liter were 13 (range 9-33) and 59 (range 22-259), respectively. Circulating T cells were primarily CD4(-)/CD8(+) with fewer than 0.2 10(9)CD4(+) cells/liter throughout the first 6 months. CD19(+) cells and CD56(+) cells were not detectable up to day +35 posttransplant. At 1 year posttransplant, 16 evaluable patients had stable hematopoiesis with 2.3 x 10(9) ANC/liter (range 0.8-4.1), 1.4 x 10(9) lymphocytes/liter (range 0.5- 2.0) and 251 x 10(9) PLT/liter (range 35-490). After the completion of hematopoietic reconstitution, six events of severe septicemia/septic shock were noted. Six children had severe VZV infections, and 2 had EBV-associated lymphoproliferation. Thirteen patients are alive with a median follow-up of 40 months (range 2-54). Ten patients have died; 8 relapsed or developed progressive disease, 1 died from nondocumented pneumopathy at day 56, and 1 developed AML-M4 at 3 years posttransplant. CONCLUSIONS: In children, CD34(+) cell transplantation can be accomplished with a reduction of neuroblastoma cell inoculum in the selected graft as assessed by RT-PCR analysis. CD34(+) cell grafts provide successful neutrophil reconstitution. However, delayed platelet recovery, persistent decrease in CD4(+) lymphocyte levels and a high incidence of serious and life-threatening late infections were observed in these children. There remains a critical need to evaluate any real clinical benefit of CD34(+) cell autografts in neuroblastoma patients.

Use of recombinant human granulocyte colony-stimulating factor to increase chemotherapy dose-intensity: a randomized trial in very high-risk childhood acute lymphoblastic leukemia.

PURPOSE: To determine whether the use of a recombinant human granulocyte colony-stimulating factor ([G-CSF] lenogastrim) can increase the chemotherapy dose-intensity (CDI) delivered during consolidation chemotherapy of childhood acute lymphoblastic leukemia (ALL). PATIENTS AND METHODS: Sixty-seven children with very high-risk ALL were randomized (slow early response to therapy, 55 patients; translocation t(9;22) or t(4;11), 12 patients). Consolidation consisted of six courses of chemotherapy; the first, third, and fifth courses were a combination of high-dose cytarabine, etoposide, and dexamethasone (R3), whereas the second, fourth, and sixth courses included vincristine, prednisone, cyclophosphamide, doxorubicin, and methotrexate (COPADM). G-CSF was given after each course, and the next scheduled course was started as soon as neutrophil count was > 1 x 10(9)/L and platelet count was > 100 x 10(9)/L. CDI was calculated using the interval from day 1 of the first course to hematologic recovery after the fifth course (100% CDI = 105-day interval). RESULTS: CDI was significantly increased in the G-CSF group compared with the non-G-CSF group (mean +/- 95% confidence interval, 105 +/- 5% v 91 +/- 4%; P <.001). This higher intensity was a result of shorter post-R3 intervals in the G-CSF group, whereas the post-COPADM intervals were not statistically reduced. After the R3 courses, the number of days with fever and intravenous antibiotics and duration of hospitalization were significantly decreased by G-CSF, whereas reductions observed after COPADM were not statistically significant. Duration of granulocytopenia was reduced in the G-CSF group, but thrombocytopenia was prolonged, and the number of platelet transfusions was increased. Finally, the 3-year probability of event-free survival was not different between the two groups. CONCLUSION: G-CSF can increase CDI in high-risk childhood ALL. Its effects depend on the chemotherapy regimen given before G-CSF administration. In our study, a higher CDI did not improve disease control.

Oral complications during treatment of malignant diseases in childhood: effects of tooth brushing.

During anticancer treatment, oral lesions considerably aggravate the child's clinical condition and increase the risk of infection. This prospective study evaluated the incidence, nature and chronology of oral complications arising during the first 6 weeks of chemotherapy. 131 children were included in this study, and their oral and dental health evaluated on enrolment. Each child was observed once a week, for 6 weeks. Fifty-two per cent (68/131) of the children presented with at least one oral lesion. Two oral healthcare regimens (with or without tooth brushing) were evaluated. Tooth brushing significantly reduced the number of children affected. Standardised multicentre studies should permit the definition of oral care regimens which would eliminate pain and reduce the risk of infection in children hospitalised for cancer.

Etoposide and carboplatin: a highly effective combination in relapsed or refractory Wilms' tumor--a phase II study by the French Society of Pediatric Oncology.

PURPOSE: Since we had previously demonstrated encouraging efficacy of etoposide in patients with relapsed or refractory Wilms' tumor (WT), the likely synergism between etoposide and platinum compounds prompted us to conduct a phase II study of a combination with carboplatin. PATIENTS AND METHODS: Twenty-six relapsed or refractory WT patients were included in a phase II study of two courses of combination etoposide 100 mg/m2/d for 5 days and carboplatin 160 mg/m2/d for 5 days, with a 21-day interval between the two courses. Initial stages were I (n = 2), II (n = 8), III (n = 6), IV (n = 6), V (n = 3), and unknown (n = 1). Sites of diseases were lung(s) (11 patients), abdomen-pelvis or liver or primary tumor (six patients), and multiple (eight patients). Histology was unfavorable in three of 26 patients. RESULTS: Complete response (CR) was documented in eight patients and partial remission (PR) in 11 (overall response rate, 73%). Stable disease (SD) was observed in five patients and progressive disease (PD) in two. Thrombocytopenia (grade IV) was the major toxicity, and platelet transfusions were required in all but two patients. Grade III anemia and grade III to IV neutropenia were seen in 19 and 23, respectively, of 25 assessable first courses. Venoocclusive disease of the liver was fatal in one child who had undergone irradiation to the whole abdomen, 8 weeks before study. CONCLUSION: Combination etoposide and carboplatin has impressive activity in refractory or relapsed WT at the cost of high-grade hematologic toxicity, especially thrombocytopenia. It is of great interest in second-line therapy, since eight of 26 patients are still alive in continuous CR (median follow-up duration, 40 months; range, 24 to 56). This combination deserves further investigation as first-line or consolidation treatment.

Investigation of an hepatitis A outbreak in a rural squatting community associated with a contaminated water-source in County St. George East, Trinidad - abstract

Following a report of a confirmed case of Hepatitis A in a child, a cross sectional epidemiological and an environmental survey were done on the total population ( about 90 households) of a village adjacent to the Arima river from April to September, 1989. The residents had no legal claim to the land and there was no pipe-bourne water supply or scavenging service to the area. Cases of Hepatitis A were identified based on clinical signs and symptoms, and a case control analysis was done using affected and non-affected households. Based on case definition criteria, the attack rate was 22 per cent and 30 cases were found. The age distribution was typical of Hepatitis A, and an epidemic curve had some features of both a common source and a propagated source epidemic. Highly significant were exposures related to using the river as a water source, using a spring and a household size > 4. It was concluded that there was an Hepatitis A outbreak, and the initial source was a river which collected waste from the nearby town and the effluent from a water treatment plant. This outbreak serves as a useful indicator of declining socio-economic conditions and deteriorating environmental standards (AU)

[Treatment of malignant intracranial germ-cell tumors in children. 7 cases]. / Traitement des tumeurs germinales malignes intracrâniennes de l'enfant. Sept cas.

Seven children, aged from 9 to 16 years, with intracranial germ cell tumour received post-operative chemotherapy prior to radiotherapy. Treatment consisted of several courses of vinblastine, bleomycin and cisplatin alternating or not with courses of cyclophosphamide and actinomycin D. In the 6 children whose tumours secreted alphafoetoprotein or chorionic gonadotrophin, chemotherapy brought these markers down to normal. Tumoral regression at radiology exceeded 75 per cent in 6 patients. These results demonstrate the effectiveness of chemotherapy against intracranial germ cell tumours such as pure germinomas or secreting tumours. They encourage the systematic use of pre-irradiation chemotherapy in order to reduce the radiation doses delivered and to improve the prognosis.

[Evaluation of the activity of leukocytes during experimental periodontitis in the monkey]. / Evaluation de l'activité des leucocytes au cours d'une parodontite expérimentale chez le singe.

Polymorphonuclear leucocytes play an important role in the defense mechanisms and destruction of periodontal tissues. The leucocytes number and activity were compared during an induced periodontitis in 3 Cercopithecus cephus. On day 0, the 3 animals presented a localized marginal gingivitis. On 2 animals a severe marginal periodontitis was induced unilaterally: 42 days later leucocytes were sampled in the peripheral blood, in the gingival blood and in the gingival sulcus on the experimental and control sites as well as on the 2 hemijaws of the control animal. For each sample, a leucocyte count and a chemiluminescence test were done. Different results related to the disease severity were obtained with these tests for gingival blood and sulcular fluid.

[Diagnosis and follow-up of Russel's diencephalic cachexia by echography, x-ray computed tomography and nuclear magnetic resonance]. / Diagnostic et surveillance de la cachexie diencéphalique de Russel par échographie, tomodensitométrie et résonance magnétique nucléaire.

A diencephalic astrocytoma was diagnosed by ultrasonography in a 5 months old girl with nystagmus and emaciation. A 27 months follow-up with ultrasonography, computed tomography and magnetic resonance imaging, showed an initial improvement after irradiation and afterwards the development of complications with ventricular dilatation and parenchymal calcifications.
