ABSTRACT

OBJECTIVE: To analyze traits of metabolic syndrome (MetS) in medulloblastoma survivors. SUBJECTS AND METHODS: Sixteen childhood medulloblastoma survivors aged 18.0 (4.4) years, with history of craniospinal radiation therapy (RT) were compared with nine control subjects matched by age, gender, and body mass index, according to fat distribution, metabolic and cardiovascular variables. RESULTS: Medulloblastoma patients showed increases in waist circum-ference and its relationships (all p < 0.05), and HOMA1-IR (p = 0.006), which were modified by growth hormone (GH) secretion status. However, these increases were within normal range. CONCLUSIONS: Adolescent and young adult survivors of medulloblastoma showed centripetal fat deposition and decreased insulin sensitivity, associated with GH status. Pediatric brain tumor survivors following RT should be monitored for the diagnosis of MetS traits predisposing to cardiovascular disease.


OBJETIVO: Analisar características que predispõem para síndrome metabólica (SM) em sobreviventes de meduloblastoma. SUJEITOS E MÉTODOS: Dezesseis sobreviventes de meduloblastoma pediátrico, 18,0 (4,4) anos, história de radioterapia (RT) cranioespinhal, comparados a nove controles pareados por idade, sexo e índice de massa corporal, de acordo com distribuição de gordura, variáveis metabólicas e cardiovasculares. RESULTADOS: Pacientes com meduloblastoma mostraram aumento da cintura e relações (todos p < 0,05) e HOMA1-IR (p = 0,006), modificados pela secreção do hormônio de crescimento (GH), mas dentro dos limites de normalidade. CONCLUSÕES: Sobreviventes adolescentes e adultos jovens de meduloblastoma apresentaram deposição centrípeta de gordura e diminuição da sensibilidade à insulina, associados ao estado do GH. Sobreviventes de tumor cerebral pediátrico que receberam RT devem ser monitorados para diagnosticar fatores para SM predispondo à doença cardiovascular.

ABSTRACT

Introduccion: La deficiencia de GH (DGH) y la radioterapia espinal (RE) han sido implicadas en la etiología de la talla adulta (TA) baja en los sobrevivientes de meduloblastoma en la niñez. Sin embargo la dinámica del crecimiento luego del diagnóstico tumoral y la efectividad de la Hormona de crecimiento biosintética recombinante humana (rhGH) sobre la TA en comparación con sobrevivientes no tratados con rhGH no han sido reportadas. Objetivo. Evaluación de la talla (T) SDS (SDST) desde el diagnóstico del meduloblastoma y el efecto de la rhGH en pacientes con DGH comparando con pacientes no tratados con rhGH y con pacientes con craniofaringioma y DGH, tratados con rhGH. Analizar si había alguna diferencia en la sobrevida libre de eventos en los pacientes con meduloblastoma al ser tratados con rhGH. Material Clínico y Métodos. Catorce pacientes con meduloblastoma recibieron rhGH hasta la TA, grupo meduloblastoma tratado con GH (GrMGH). Diecinueve pacientes rechazaron la terapia con rhGH, grupo meduloblastoma control (GrMC). Se midieron la talla parada (T) y la talla sentada (Tsent). Ocho pacientes con craneofaringioma recibieron rhGH hasta la TA (GrCra). Se realizó seguimiento de 72 pacientes con meduloblastoma, 20 con tratamiento con rhGH. Resultados. En GrMGH, la media±DS SDST disminuyó de 0.09±0.63 al diagnóstico del tumor a -1.38±0.91 al diagnóstico del DGH, y a -1.90±0.72 al comienzo de rhGH, p<0.01, pero se mantuvo sin cambios durante el tratamiento con rhGH (TA -2.12±0.55). En GrMC la SDST (-0.25±0.88) no fue diferente de GrMGH al diagnóstico del tumor, pero fue -3.40±0.88 a la TA, significativamente menor que en GrMGH, p=0.001. La Tsent SDS a la TA (-4.56±0.82) fue significativamente menor que al comienzo de rhGH (-2.86±0.75), p=0.003, y no fue diferente de GrMC (-4.85±1.77). El GrCra mostró la mayor ganancia de talla (GT = TA-SDSTinicial), p< 0.007, y la menor pérdida de talla (PT= Tblanco - TA), p < 0.0001. Conclusión. El tratamiento con rhGH mejora la TA en sobrevivientes de meduloblastoma en la niñez con DGH, pero no el crecimiento espinal. Las características del crecimiento y la respuesta a rhGH son diferentes en GrMGH y en GrCra, mientras que el primer grupo sólo pudo mantener la talla relativa, el segundo mostró una franca recuperación del crecimiento. Además no hubo diferencias en la sobrevida libre de eventos en los pacientes con meduloblastoma con y sin tratamiento con rhGH (AU)


Background. GH deficiency (GHD) and spine irradiation (SI) have been implicated in the mechanism of reduced adult height (AH) in childhood survivors of medulloblastoma. However, growth dynamics after tumor diagnosis and the effectiveness of (rhGH) Recombinant human Growth Hormone on AH in comparison with rhGH-untreated survivors has not been reported. Aim. Follow up of height (H) SDS (HSDS) after diagnosis of meduloblastoma, and the effect of rhGH in GHD meduloblastoma patients. Comparison with GH-untreated GHD meduloblastoma patients and with GHD craniopharyngioma patients treated with rhGH. To evaluate event free survival in medulloblastoma patiens treated with rhGH. Clinical Material and Methods. Fourteen survivors of medulloblastoma received rhGH treatment until AH, Medulloblastoma GH-treated group (MGHGr). Nineteen patients refused rhGH therapy, GH-untreated Control Medulloblastoma Group, (MCGr). Standing H and sitting H (SitH) were measured. Eight patients with craniopharyngioma received rhGH treatment until AH (CraGr). 72 patients with medulloblastoma were followed up, 20 with rhGH. Results. In MGHGr, mean±SD HSDS decreased from 0.09±0.63 at tumor diagnosis to -1.38±0.91 at diagnosis of GHD, and to -1.90±0.72 at the onset of rhGH, p<0.01, but it remained unchanged during rhGH (AH -2.12±0.55). MCGr HSDS (- 0.25±0.88) was not different from MGHGr at tumor diagnosis, but it was -3.40 ± 0.88 at AH, significantly lower than in MGHGr, p=0.001. SitH SDS at AH (-4.56±0.82) was significantly lower than at the onset of rhGH (-2.86±0.75), p=0.003, and it was not different from MCGr (-4.85 ± 1.77). CraGr showed the highest height SDS gain (HG = FH ­ startHSDS), p<0.007, and the lowest height lost (HL = targetH - AH), p< 0.0001. Conclusions. rhGH treatment improves AH in GH-deficient childhood medulloblastoma survivors but not spinal growth. Growth pattern and response to rhGH differed in MGHGr and CraGR, while the former just could maintain height SDS under treatment, the latter showed a clear catch up growth. There wasn't any difference in the event free survival in medulloblastoma patients with or without rhGH (AU)

ABSTRACT

Peduncular hallucinations are formed visual images often associated with sleep disturbance and are caused by lesions in the midbrain, pons and diencephalon. In present case report, a four year child, who was operated for midline posterior fossa medulloblastoma developed peduncular hallucinations on 3rd post operative day. Traction trauma or the compression of mid brain was thought to be the most possible cause of hallucinations.

ABSTRACT

Relatamos o caso de paciente do sexo feminino, com 32 anos de idade, com sintomas álgicos na regiao occipital, compressivos de forte intensidade e com irradiaçao frontal, supraorbitária e orbitária esquerda, relacionada a movimentos de flexao e extensao do pescoço, com característica lancinante e duraçao de até 9 segundos. A investigaçao radiológica, clínica, neurocirúrgica e neuropatológica evidenciou um meduloblastoma que aderia à membrana tentorial promovendo espessamento e compressao das estruturas venosas desta regiao. Atribuímos ao estímulo mecânico sobre estas estruturas vasculares tentoriais as manifestaçoes álgicas envolvendo as conexoes entre o trigêmeo e os primeiros segmentos medulares cervicais.

ABSTRACT

Os autores apresentam 17 casos de meduloblastomas operados no Serviço de Neurocirurgia do Hospital Cristo Redentor no período de 11 anos (1976-1986). Foi observada maior incidência em pacientes jovens (10 meses a 29 anos de idade) e no sexo masculino (2:1). Os sinais e sintomas mais comuns foram os relativos a hipertensäo intracraniana (HIC) e distúrbios cerebelares, sendo que o intervalo de tempo médio entre o início da sintomatologia e a hospitalizaçäo foi de dois meses e meio. Todos os pacientes foram submetidos a uma craniectomia suboccipital em posiçäo sentada, sendo a derivaçäo ventrículo-peritoneal (DVP) realizada previamente em cinco casos. A mortalidade pós-operatória foi de 29,4%

ABSTRACT

Se presenta la asociación de dos tumores, histológicamente diferentes, ubicados en la fosa posterior de un mismo paciente; y que se hicieron manifiestos con cinco años de diferencia y un tratamiento quirúrgico y radioterápico de por medio. Casos similares han sido observados por otros autores, no obstante es la primera vez que se comunica esta asociación en nuestro país. La probabilidad por azar de que estos dos tumores se presenten en la vida de una persona es de uno en 10 billones. Hay evidencias en la literatura relacionada, tanto clínica como de laboratorio, que implican a la radioterapia en la aparición del segundo tumor; y que en este caso corresponde a un astrocitoma fibrilar G II. En este caso habría actuado, ya sea dejando un remanente diferenciado hacia la línea astrocítica del tumor inicial, que era un meduloblastoma o induciendo un nuevo tumor en tejido nervioso previamente sano
