2 Cases of Peripheral Facial Nerve Palsy Caused by Leukemia and Brain Stem Tumor / 대한소아신경학회지

Idiopathic facial palsy of the peripheral type is the most common facial palsy. However, the rate of incident is much lower in children under 10 years. In children, many other conditions can cause peripheral facial nerve palsy. We present the cases of 2 children with whom the initial manifestation of their leukemia and brain stem tumor were shown through the peripheral type of facial nerve palsy. These cases should alert physicians to consider other serious causes in younger children with facial palsy.

Nursing care of postoperative patients with brain stem tumor complicated with stress hyperglycemia / 中国实用护理杂志

Objective To explore nursing methods of postoperative patients with brain stem tumor complicated with stress hyperglycemia. Methods The medical and nursing measures of 56 postoperative patients with brain stem tumor complicated with stress hyperglycemia were analyzed retrospectively. Results Among 56 cases, 48 cases were clinically cured, 6 cases was improved, 2 cases died of multiple organ failure. Conclusions It is especially important to intensify insulin therapy, necessary to closely observe the patients' consciousness, pupils and the change of vital signs. Meanwhile, strengthening nursing on common complications such as infection and gastrointestinal hemorrhage, and paying more attention to patients' dietary, mental state and rehabilitation are also important measures.

Impacto da adição da temozolamida à radioterapia no tratamento de crianças portadoras de tumor de tronco cerebral / Impact of the addition of temozolomide to radiotherapy in the treatment of children with brain stem tumors

OBJETIVO: Analisar o impacto da adição da temozolamida à radioterapia em tumores de tronco cerebral em crianças. MATERIAL E MÉTODO: Entre 2000 e 2005 foram analisadas, retrospectivamente, 64 crianças com tumor do tronco cerebral. Dessas crianças, 32 receberam temozolamida(grupo 1) e 32 não a receberam (grupo 2). RESULTADOS: A idade mediana no grupo 1 foi de 8,2 anos e no grupo 2 foi de 7,5 anos. A localização tumoral era predominantemente difusa (53%) emambos os grupos. Todos os pacientes receberam radioterapia com doses superiores a 50 Gy. No grupo1 foram ministrados nove ciclos, em média, de quimioterapia (3û14 ciclos). O tempo de progressão de doença foi de 7,9 meses no grupo 2 versus 13,8 meses no grupo 1. A sobrevida global foi de 8,8 meses (0,3û30,9 meses) no grupo 1 e de 14,6 meses (4,3û33 meses) no grupo 2. CONCLUSÃO: A utilização da temozolamida após a radioterapia proporcionou aumento da sobrevida, deseis meses em média, nos pacientes pediátricos com tumor do tronco cerebral.

OBJECTIVE: To analyze the impact of adding temozolomide to radiotherapyin pediatric brain stem tumors. MATERIAL AND METHOD: Between 2000 and 2005, 64 children with brain stem tumor were analyzed: 32 received temozolomide (group 1) and 32 did not(group 2). RESULTS: The median age of patients in group 1 was 8.2 year-old and in group 2 was 7.5 year-old. The predominant tumoral localization was diffuse (53%) in both groups. All of the patients were submitted to radiotherapy. In group 1, the median number of temozolomide cycles was 9 (3û14 cycles). Time of disease progression was 7.9 months in group 2 versus 13.8 months in group 1. Overall survival was 8.8 months (0.3û30.9 months) in group 1 and 14.6 months (4.3û33 months) in group 2. CONCLUSION: In our institution,adding temozolomide to radiotherapy increased the overall survival in approximately six months in brain stem pediatric tumors.

Brain-Stem Gliomas:Growth Patterns, Pathology, and Prognosis

A retrospective study of 29 cases of brain-stem gliomas(BSG's) from 1989 to 1993, was performed to determine prognostic factors. Our study also analyzed clinical features, growth patterns, pathologic findings and modalities of treatment in patients with brain-stem gliomas. The patients ranged in age from 6 to 65 years, most commonly in the first decade. The symptom duration prior to diagnosis was 1/2 to 6 months(mean 1 1/2 months). The most common symptom and sign were cranial nerve palsies, especially 6th or 7th cranial nerve. The growth patterns of BSG's were classified into diffuse tumors(7 patients), exophytic(9 patients), focal(2 patients) and cervicomedullary(1 patient). Twenty three of 29 patients were diagnosed pathologically by means of stereotactic biopsy(13 patients) and ope surgery(10 patients). The Pathologic findings were low grade astrocytoma in 9 patients, oligodendroglioma(3 patients), malignant astrocytoma(7 patients), and glioblastoma mulitiforme(4 patients). A significant correlation between diffuse growth pattern and malignant pathologic finding could be obtained(P=0.05). The methods of radiation therapy for BSG's were conventional(10 patients), hyperfractionated(13 patients), and Gamma knife radiosurgery(6 patients). The median survival time was 12 months. The Poor prognostic factors determined in our study were 1) short symptom duration prior to diagnosis(< or = 2 months), 2) diffuse growth pattern, 3) malignant pathologic finding, 4) tumor without cystic portion, and 5) tumor without hydrocephalus.

Radiotherapy Result of Brain Stem Tumors / 대한치료방사선과학회지

Twenty five patients with tumors of the brain stem were treated with radiotherapy between 1979 and 1987. Histological diagnosis could be obtained in 6 cases, and other 19 patients were diagnosed by neurologic findings and CT or MRI. Eighteen patients were treated by radical radiotherapy and 6 patients received both operation and radiotherapy, while 1 patient received chemotherapy after radiotherapy. Total dose ranged from 50 Gy to 55 Gy. By an clinical scoring scale at 2 months after radiotherapy, no complete response was obtained, but 16 cases achieved partial response, 2 cases were stable, and 4 cases were deteriorated. The overall survival rate at 3 years was 36%. Age, performance status at diagnosis, degree of cranial nerve involvement, CT pattern of post-contrast enhancement, and clinical response by scoring scale were correlated with survival.
