High dose dexamethasone suppression testing has been widely employed in the differentiation between pituitary ACTH-dependent hypercortisolism [Cushing's disease (CD)] and the ectopic ACTH syndrome. We hypothesized that the high dose dexamethasone suppression test as it is performed in practice does not improve the ability to differentiate between these two types ...

BACKGROUND: Inferior petrosal sinus sampling (IPSS) is a useful investigative technique in the differential diagnosis of ACTH-dependent Cushing's syndrome. Diagnostic accuracy is improved by the administration of corticotrophin releasing-factor (CRF) during the procedure to stimulate ACTH secretion. We hypothesized that, given the unavailability of CRF in Australia, stimulation of ACTH ...

A two-month-old infant developed a vascular tumor of the right flank which upon biopsy proved to be a spindle cell hemangioendothelioma. The increased capillary bed characterizing the neoplasm caused a severe thrombocytopenia together with a consumption coagulopathy (Kasabach-Merritt syndrome). The patient, who was dependent on platelet transfusions, improved quickly after ...
La Brocca A - - 1997
The present report describes a 54-year-old woman with a history of recurrent thromboembolic events. The clinical and physical examination led to suspect Cushing's syndrome. Screening tests (urinary free cortisol excretion and 1 mg dexamethasone) were inconclusive, but a detailed endocrine work up confirmed the presence of ACTH-dependent hypercortisolism. The patient ...

A clinical case is presented illustrating a previously unreported association of (1) neurocardiogenic syncope of new onset in a 57-year-old man, (2) Prinzmetal's angina, and (3) bronchogenic carcinoma of the lung. Initiation of aggressive chemotherapy resulted in immediate suppression of both cardiac manifestations. This newly described paraneoplastic syndrome is discussed.
Balakumar T - - 1997
We describe a 6 year-old boy who presented with bilateral gynaecomastia, pseudoprecocious puberty and facial features suggestive of Cushing's syndrome. The underlying pathology was a right adrenocortical adenoma which was secreting oestradiol, androgens and cortisol. All the biochemical abnormalities normalised within one week of right adrenalectomy. To our knowledge this ...
Chow C P - - 1997
BACKGROUND: Lumbosacral plexopathy is a complication of diabetes mellitus. Conn's syndrome from an aldosterone secreting adenoma may be associated with hypokalemia and rhabdomyolysis but mild hyperglycemia also usually occurs. METHODS: Case description. RESULTS: A 70-year-old male diagnosed as having Conn's syndrome, hypokalemia and mild hyperglycemia developed rhabdomyolysis and lumbar plexopathy ...

PURPOSE: We attempted to confirm the possibility and feasibility of laparoscopic adrenalectomy via the retroperitoneal approach, and to compare results of the transperitoneal and retroperitoneal approaches. MATERIALS AND METHODS: Three men and 8 women (mean age 39.6 years) with functioning adrenocortical tumors (primary aldosteronism in 5 and Cushing's syndrome in ...
Izumi T - - 1997
We report a man with pre-Cushing's syndrome due to ACTH-independent bilateral macronodular adrenocortical hyperplasia. Plasma ACTH was low and urinary 17-OHCS was not suppressed by a high dose of dexamethasone (8 mg), but plasma cortisol was responsive to exogenous ACTH. The adrenal glands were enlarged and contained multiple nodules composed ...
Miyajima A - - 1997
A 53-year-old man who had been followed up for the treatment of hypertension presented with a bilateral adrenal mass during a screening CT scan. Other imaging studies and biochemical tests suggested Cushing's syndrome caused by a pituitary-independent and adrenal-dependent bilateral adrenal tumor. A total adrenalectomy was performed and the pathological ...
Lin C L - - 1997
To determine the efficacy of cortisol and its metabolite, cortisone, measured simultaneously by high performance liquid chromatography (HPLC) in the diagnosis of Cushing's syndrome, we retrospectively reviewed the histories of 29 surgically proven Cushing's syndrome patients (20 Cushing's disease, 5 ectopic ACTH syndrome, and 4 adrenal Cushing's syndrome) and 6 ...
Loh K C - - 1997
A 17-year-old female with a large mass in the left thorax presenting with ectopic Cushing's syndrome is described. Biochemical evaluation revealed a corticotropin(ACTH)-dependent hypercortisol state. Surgical resection of the tumour resulted in clinical remission and correction of hypercortisolism and normal plasma ACTH levels. The histology was that of an atypical ...

Schmidt syndrome consists of adrenal insufficiency and Hashimoto's thyroiditis, which are probably caused by an autoimmune process. We encountered a patient who manifested severe generalized fatigue due to Schmidt syndrome recurrently. The endocrinological examination tests on the patient showed that the increase in thyroid stimulating hormone (TSH) and ACTH concentrations ...
Loh K C - - 1996
A young female adult with Cushing's syndrome arising from ectopic production of corticotropin (ACTH) from an adrenal pheochromocytoma showed spontaneous clinical and biochemical remission of hypercortisolism after a brief period of ketoconazole administration. Despite continued remission of the hypercortisolism over the next 18 months, there was progressive catecholamine hypersecretion with ...

The effects of somatostatin and its analogs have been studied in different subclasses of patients with Cushing's syndrome (due to Cushing's disease, ectopic corticotropin [ACTH]- and/or corticotropin-releasing hormone [CRH]-secreting tumors, or ACTH-independent Cushing's syndrome) and in patients with Nelson's syndrome. In most patients with untreated Cushing's disease, octreotide does not ...
von Werder K - - 1996
Eutopic corticotroph pituitary adenomas and adrenal cortisol-producing adenomas do not usually express somatostatin receptors. However, ectopic corticotropin (ACTH)-producing tumors often express somatostatin receptors. Thus, the octreoscan can detect and localize tumors in 80% of patients with ectopic ACTH syndrome, and so it can be used to differentiate between eutopic and ...

OBJECTIVE: Exophthalmos was noted in 4 of the 12 patients reported by Harvey Cushing in 1932. Although exophthalmos has often been included in clinical descriptions, no previous study has reported actual measurements in patients with active and treated Cushing's syndrome, and in control patients. The aim of this study was ...

1. We set out to investigate whether the administration of naloxone alone, naloxone plus vasopressin (AVP) or naloxone plus alprazolam to patients with Cushing's syndrome would result in a blunted dynamic response of the pituitary-adrenal axis compared with normal volunteers. Cushing's syndrome is often difficult to diagnose. It would be ...

We describe a case of Cushing's syndrome caused by a medullary thyroid carcinoma (MCT) secreting corticotropin-releasing-hormone (CRH) in a young woman presenting mucosal neuromas located on the top of the tongue and eyelid areas. Laboratory studies showed, basally and after dexamethasone suppression test, serum cortisol and plasma pituitary corticotrophin (ACTH) ...
Borretta G - - 1996
The coexistence of an unilateral adrenal macronodule and Cushing's disease is well documented in only few reports. We hereby describe two patients with ACTH-dependent Cushing's syndrome and asymmetric adrenal involvement. In both patients the left-sided adrenal contained a nodule sized 1.5 and 1.4 cm, respectively, while the contralateral gland appeared ...
Tsigos C - - 1996
The diagnosis of endogenous Cushing's syndrome requires demonstration of an increased cortisol secretion rate, best achieved by urinary free cortisol excretion determinations. In borderline or confusing cases, loss of diurnal cortisol rhythmicity, a combined dexamethasone/corticotropin releasing hormone (CRH) test, or close monitoring of the patient for a few months will ...
Ntalles K - - 1996
An extremely rare case of a 39-year-old man with Nelson's syndrome and paratesticular tumours is presented. The patient had undergone bilateral adrenalectomy at the age 23 years for Cushing's syndrome. Later he developed skin and mucosal hyperpigmentation. Nelson's syndrome was diagnosed, and he underwent transfrontal hypophysectomy. At age 29, the ...

The efficacy of a nocturnal 8 mg dexamethasone suppression test (nocturnal DST) was compared with that of the standard high-dose dexamethasone suppression test (standard DST) in identifying the cause of endogenous Cushing's syndrome in 10 proven cases with Cushing's disease, 20 with adrenal tumours, and one with ectopic ACTH syndrome. ...
Kelestimur F - - 1996
We have administered octreotide, 100 micrograms tid, to a 27-year-old man with Nelson's syndrome. After seven days of therapy, adrenocorticotropin levels fell to 54% of initial values, and some shrinkage of the tumour was observed. This study indicates that octreotide therapy may have a role in the treatment of Nelson's ...
Saito T - - 1996
We report the case of a spontaneously ruptured adrenal adenoma which caused Cushing's syndrome. The 34-year-old female patient had severe left-side back pain and anemia. Computerized tomography disclosed a retroperitoneal hemorrhage and a 4-cm mass on the left which was considered to be an adrenal tumor. An operation was successfully ...
Tsagarakis S - - 1995
Ectopic ACTH secretion due to occult carcinoid tumours is an occasional cause of ACTH dependent Cushing's syndrome. In many cases the ectopic source may be obvious, but sometimes no obvious source is evident, the so-called occult ectopic syndrome. Due to their small size, localization of such occult tumours, particularly bronchial ...
Stewart P M - - 1995
A characteristic feature of the ectopic ACTH syndrome is a state of mineralocorticoid excess, although the etiology remains obscure. Some forms of endocrine hypertension, such as licorice ingestion, have been explained by cortisol acting as a mineralocorticoid in the setting of inhibition or deficiency of 11 beta-hydroxysteroid dehydrogenase (11 beta ...
Yu K C - - 1995
BACKGROUND: Iodocholesterol scintiscanning (IS) is a noninvasive, functional diagnostic test. We report our experience with IS as an adjunct for adrenal surgery for Cushing's syndrome. METHODS: Between April 1983 and October 1994, 23 patients with Cushing's syndrome from benign primary adrenal disease underwent IS and computed tomography (CT) and/or magnetic ...

To further clarify the significance of renal kininases in patients with Cushing's syndrome, daily urinary excretions of total kininase, kininase I, Ii and neutral endopeptidase 24.11 (NEP) were examined and evaluated for the relations between plasma cortisol level and these kininases. Urinary total kininase kininase I, II and NEP were ...
Uchida K - - 1995
A 76-year-old diabetic woman with non-obese Cushing's syndrome developed poor glycemic control with glibenclamide. She presented with a slight weight loss while bedridden due to a fall. Cushing's syndrome in this patient was suspected because of hypercortisolemia with eosinopenia, and adrenal Cushing's syndrome was diagnosed by endocrine and radiological examinations. ...
Newell-Price J - - 1995
OBJECTIVE: The diagnosis of Cushing's syndrome remains a major challenge in clinical endocrinology. Various screening tests are commonly used to support a biochemical diagnosis in the context of clinical suspicion. The aim of this study was to compare the sensitivity in the diagnosis of Cushing's syndrome of a single in-patient ...
Lavallée G - - 1995
A 30-year-old woman had uterine bleeding and hypotension after delivery. Hyponatremic seizures and a mild headache prompted early neuroimaging, which disclosed an enlarged nonhemorrhagic pituitary gland with subsequent involution consistent with pituitary apoplexy (Sheehan syndrome). Endocrinologic investigation confirmed a partial pituitary insufficiency with subsequent improvement to almost normal status.
Dorn L D - - 1995
OBJECTIVE: Prolonged elevations of glucocorticoids have been linked to the effective disturbances experienced by patients with Cushing's syndrome. Major depression has been most commonly reported in patients with endogenous Cushing's syndrome. The purpose of this study was to determine whether these patients experience melancholic or 'atypical' subtype depression and to ...

Beckwith-Wiedemann syndrome is a rare condition (1/13,700 live births) occurring in both inherited and sporadic forms in the population. It is manifest as a fetal overgrowth syndrome, in which hypertrophy dominates the clinical picture. An additional complication is that these children are predisposed to a specific subset of childhood neoplasms, ...
Mizuno Y - - 1995
Four neuropeptides; cerebellin, corticotropin-releasing hormone (CRH), neuropeptide Y and somatostatin were studied by radioimmunoassay in the postmortem human brains obtained from three patients with olivopontocerebellar atrophy (OPCA) and one with Shy-Drager syndrome. Significant decreases in cerebellin and CRH concentrations were found in the cerebellar hemisphere of these diseases compared with ...
MacGibbon A L - - 1995
Cushing syndrome in pregnancy is rare. This is explained by the syndrome's association with amenorrhoea, oligomenorrhoea, infertility and abortions. Cushing syndrome commonly presents with hypertension, weight gain, diabetes, striae or truncal obesity, all of which can be consistent with pregnancy in women without Cushing syndrome. We describe a case of ...
Verloes A - - 1995
We report on a child who died in the neonatal period. Major external anomalies included foetal overgrowth, macroglossia, and ambiguous genitalia (micropenis and perineoscrotal hypospadias with cryptorchidism). Necropsy showed a large right diaphragmatic hernia, visceromegaly, multicystic kidney dysplasia, Langerhans islet hyperplasia, nephroblastomatosis, multiple adrenal adenomas, and dysplastic testicles. The child ...
Tsigos C - - 1995
Excess endogenous glucocorticoid production, whether ACTH-dependent or ACTH-independent, results in the classic clinical and biochemical picture of Cushing's syndrome. The diagnosis requires demonstration of an increased cortisol secretion rate, best achieved using determination of urinary free cortisol as an index. In mild cases, distinction from the hypercortisolism of pseudo-Cushing states ...
Boonen S - - 1995
Epidural steroid injections are widely used for the treatment of lumbago and sciatica although their efficacy has not yet been demonstrated in a convincing way. Moreover, systemic complications, although rare, have been documented. The present case report illustrates that even a single low-dose epidural injection may induce Cushing's syndrome and ...
Richardson J - - 1995
A 54-year-old man who had an appearance strongly suggestive of Cushing's syndrome, collapsed after the removal of a carcinoid tumour of the thymus. The clinical suspicion of acute adrenal insufficiency was supported by invasive haemodynamic data and the diagnosis was subsequently confirmed biochemically. These post-operative events were subsequently ignored and ...
Terzolo M - - 1995
We hereby describe a patient in whom chronic rifampicin treatment led to a misdiagnosis of Cushing's syndrome. He had long-standing insulin-dependent diabetes mellitus and active tuberculosis resistant to conventional treatment. The course was complicated by muscle weakness, lower limb atrophy, unstable glycemic control and hypokalemia. Ectopic Cushing's syndrome was suspected ...
