[Lymphoblastic non-Hodgkin's lymphoma: estimation of the survival of patients with the disseminated form of the disease (stages III and IV) treated by the LSA2-L2 protocol].

We analyze the survival rate in 17 pediatric patients (twelve males and five females) that were diagnoses of non-Hodgkin's lymphoblastic lymphoma (cases with Burkitt's lymphoma were excluded) during the period from 1982 to 1990. All of them were treated using the LSA2-L2 therapeutic protocol. The follow-up period ranged from 14 to 99 months (follow-up median 43 months). Staging of our newly diagnosed patients, we found 9 patients in stage III and 8 in stage IV disease. Survival was analyzed by the Kaplan-Meier method. The overall survival rate of our patients is 69.5% and the disease free survival is 62.6%. The disease free survival for separated stages is 66.5% for stage III and 58.3% for stage IV. We compare our results with other casuisties published in literature.

[Ultrasonic diagnosis of neuroblastoma].

Neuroblastoma is one of the most frequent tumors in childhood. Suprarenal area is its main abdominal location, appearing in lesser proportion in paravertebral ganglionar chains. Its prediction depends principally on the age of the patient and the pathological stage. US are the best method for its diagnosis. Its most frequent appearance is as an hyperechogenic heterogeneous mass with calcifications inside. In evaluation tumoral extension, other complementary methods such as CT and MRI should be used.

[Eosinophilic cystitis].

We report two cases of eosinophilic cystitis in children of 11 months and 11 and a half year of age respectively. The presenting symptoms were the emision of mucosanguinolent filaments in the urine in one case and with lower urinary tract symptoms and macroscopic hematuria in the other. Physical examination revealed in one of them a round, tough and painful mass in the hypogastric area. In one case we found peripheral blood eosinophilia. They both showed in the Urinalysis albuminuria, pyuria and hematuria, with the presence of eosinophils in one of them. Macroscopic examination presented in the two cases a tumoral, mamelonne mass in the wall of the bladded. The diagnosis was anatomopathologic due to the demonstration of an inflammatory infiltration, primarily of eosinophils. The clinical course was unfavourable in the case an hemicystectomy was practicated and self-limited in the one only symptomatic treatment was used.

[Values for the cortical thickness and diameter of the metacarpals of normal Aragonese children in the 1st 4 years of life. Longitudinal study].

The measurement of the metacarpal cortical thickness as well of the diameter is an accurate, simple and economic procedure in the clinical diagnosis of the growth deficiency. Our study reports the increasing values of such parameters obtained from a normal Spanish population controlled at ages 0.5, 1, 2, 3 and 4, in the growth studies center "Andrea Prader" of Zaragoza.

[Spontaneous regression of an aneurysmal bone cyst of the vertebrae after partial excision. Bibliographic review].

A case of a lumbar aneurysmal bone cyst is presented in a 5 year-9 month old girl. The characteristics of this tumor are described, specifically in the spinal area, with particular reference to the diagnostic and therapeutic difficulties referred, taking into account the existing bibliography. The partial resection has been curative, as it has been frequently written about in publication worldwide and which suggest that surgery does not have to be aggressive in unapproachable cases and that radiotherapy is unnecessary.

[Cases of symptomatic epilepsy at a regional reference neuropediatric unit].

OBJECTIVE: The objective of this study was to analyze, from an aetiological angle, the cases seen with symptomatic epilepsy by the Seccion de Neuropaediatria del Hospital Miguel Servet de Zaragoza. PATIENTS AND METHODS: We studied the cases diagnosed as having symptomatic epilepsy between May 1990 and November 1999. RESULTS: Of a total of 4,466 children assessed during the study period, the diagnosis of epilepsy was established in 461 children (10.3% of the total). This included idiopathic epilepsy in 110 cases (23.9%), cryptogenic epilepsy in 119 cases (25.8%) and symptomatic epilepsy in 232 cases (50.3%). The aetiologies of the symptomatic epilepsies were: prenatal encephalopathies in 137 cases (59%), perinatal encephalopathies in 33 (14.3%), postnatal encephalopathies (due to accidents, acquired infections and postnatal cerebrovascular accidents) in 20 (9%), tumours ( including the post-operative period) in 14 (6%), neurocutaneous syndromes in 13 (5.6%), metabolic and degenerative disorders in 13 (5.6%) and one case of vascular malformation. CONCLUSIONS: The symptomatic epilepsies make up half the epilepsies evaluated by the department of neuropaediatrics. In 59% the cause was prenatal. Other causes of symptomatic epilepsy were also represented in the series. A detailed study of these should help us to understand and manage them better. We consider aetiological aspects to be very important in the study of epilepsy, since the aetiology is one of the most important factors in prognosis.
