Intrathecal administration of opioids is a very efficient tool in the long-term control of intractable nonmalignant pain. However, despite the well known role of opioids in endocrine regulation, few data are available about possible effects on hypothalamic-pituitary function during this treatment. Seventy-three patients (29 men and 44 women; mean age, 49.2(More)
OBJECTIVE Growth hormone (GH) deficiency is associated with insulin resistance and diabetes. The aim of the current study was to determine incidence of diabetes during GH replacement therapy (GHRT) and the effect of GHRT on fasting plasma glucose concentrations and HbA(1c) in adult patients with GH deficiency. RESEARCH DESIGN AND METHODS A total of 5,143(More)
The presence of corticotropin-releasing hormone (CRH) receptors has been previously demonstrated in corticotrophs from normal pituitaries using a method combining immunocytochemistry and liquid emulsion autoradiography. The aim of this study was to compare the characteristics of the 125I-Tyr0-hCRH binding in corticotrophs from normal pituitaries (three(More)
Over a two-year period two patients were admitted to the hospital with episodes of paralysis and hypokalemia. In the first patient, familial hypokalemic periodic paralysis was initially suspected. Only several months later was Graves' disease diagnosed and this diagnosis linked to thyrotoxic periodic paralysis. The second patient came to notice after(More)
Seven patients with the co-occurrence of meningioma and pituitary adenoma are reported. Diagnosis was based on histological examination and if not available on MR imaging. Extensive review of the literature reveals only 18 other cases with this association if meningiomas appearing after radiation therapy for pituitary tumors are excluded. As in isolated(More)
A male patient is reported with benign intracranial hypertension, who presented with three periods of partial pituitary deficiency, corresponding to episodes of headaches and papilledema. No radiological signs of the empty sella syndrome were observed. Since benign intracranial hypertension has been implicated in the development of the empty sella syndrome,(More)
A female patient with a juvenile pilocytic astrocytoma and a pituitary adenoma is described. The patient also has alcaptonuria, a rare inborn error of metabolism with autosomal recessive mode of inheritance. The association of these three disorders has never been reported previously. The possible existence of a common genetic factor in the development of(More)
The association of cerebellar ataxia and non-neurological syndromes is a well known phenomenon. A 20-year-old male patient presented with a longstanding and non-progressive ataxia. Magnetic resonance examination revealed marked inferior vermian-cerebellar hypoplasia. He also showed a hypogonadism with low serum gonadotropin and prolactin levels. Chronic(More)
