Arquivos de Neuro-Psiquiatria , 1997, DOI: 10.1590/S0004-282X1997000100014
Abstract: the authors present a retrospective study of a series of eighteen patients with acromegaly diagnosed, treated and followed by the endocrinology and neurosurgery services of the hospital universitário clementino fraga filho of the federal university of rio de janeiro. the average age of the patients was 43.2% years (varying between 15 and 63). initial complaints were mainly due to somatic alterations in 83.33%; half the cases had manifestations secondary to tumor compression and 53.33% had neuro-ophtalmological alterations. hypersecretion of growth hormone was demonstrated by basal hormone determinations and dynamic tests. neuroradiological assessment showed supraselar expansion in 61.11% of cases. surgical approach was transsphenoidal in all cases. the main objetive of this study was to establish diagnostic criteria, discuss the therapeutic conduct and evaluate the results obtained, comparing them with other series of literature.

Complica??es das cirurgias hipofisárias: análise de 120 cirurgias no HUCFF-UFRJ
Arquivos de Neuro-Psiquiatria , 1999, DOI: 10.1590/S0004-282X1999000500014
Abstract: we evaluated 120 pituitary operations performed at hospital universitario clementino fraga filho of the universidade federal do rio de janeiro from 1979 to july 1998 with the aim of analysing the immediate post operative morbidity and mortality. the ages ranged from 15 to 70 years and the clinical diagnoses were: nonsecreting adenomas, 46 (38,34%); acromegaly, 30 (25%); prolactinomas, 29 (24,16%) and cushing`s disease 15 (12,5%). the main endocrine complications were : panhypopituitarism, 16 (13,34%); diabetes insipidus,15 (12,5%) and adrenocortical insufficiency, 4 (3,34%). neurological complications: infection, 13 (10,84%); and cerebrospinal fluid leakage, 6 (5%). two patients died. our results agree with those of the international literature. we identified a progressive decrease of morbidity and mortality due to surgeon's skill increase and to the uniformity of the clinical team which managed those patients.

Abstract: objective: to show a rare lesion that sometimes simulates vascular disorder of the lower extremities. method: three patients were operated and the follow-up period was eight months, the surgical technique was neurotomy of the infrapatellar and descendent branches. results: in two cases there were almost total pain resolution, and in other case improvement only. conclusion: surgical treatment yields good results in this type of internal saphenous nerve lesion, and could be useful as an alternative to conservative treatment.

Abstract: objective: to report our data of cases of failed back surgery syndrome (fbss) and surgical and nonsurgical etiologies. method: the medical charts of 121 patients submitted to laminectomy, hemilaminectomy combined with discectomy and/or foraminotomy between january 1997 and october 2004 in the instituto of neurologia deolindo couto were reviewed. the inclusion criterion was does not improve or the symptoms return after the surgery and with a minimum of three medical consultations with adequate investigation for the diagnosis. the patients had been divided in three main pre-surgical diagnosis: herniated disc, lumbar stenosis and the association of these. results: from the 121 patients submitted to spine surgical intervention, 47 (38.8%) had presented criteria for the fbss. among the 26 patients who had presented operative diagnosis of lumbar stenosis, 8 (30.7%) had presented fbss; of the 83 with disc herniation, 31 (37.3%) had the syndrome; and the 12 patients with lumbar stenosis associated with disc herniation, 7 (58.3%) had failure of the back surgery. conclusion: the failure of back surgery remains a challenge for the surgeons. there is an incessant search for the causes and the action mechanisms of this syndrome and the best method of treatment.

Abstract: this paper reports the case of a patient with a giant mucocele of the sphenoidal sinus, which presented like an intracranial mass, invading the sella and leading to pituitary dysfunction with somatotrophic and corticotrophic deficit. a literature search reveals no other reports of such cases. thus, we discuss some reported cases of intracranial masses associated with mucoceles and the reversibility of the pituitary function after decompressive surgery.
