Lymphomas arising in the adrenal are rare, and to our knowledge, 2 cases of Epstein-Barr virus (EBV)-positive diffuse large B-cell lymphomas (DLBCL) in an adrenal pseudocyst have been reported. We report an incidental EBV-positive DLBCL arising in an adrenal pseudocyst in a 58-year-old man with a 7-year history of lymphoplasmacytic lymphoma (LPL). The DLBCL was present in the fibrinous exudate, while the LPL resided in the cyst wall. The patient underwent de-roofing of the same cyst 3 years previously; review of histology revealed foci of LPL in the cyst wall, but not of DLBCL...

Aldosterone, secreted by the adrenal zona glomerulosa, enhances sodium retention, thus increasing blood volume and pressure. Excessive production of aldosterone results in high blood pressure, and contributes to cardiovascular and renal disease, stroke, and visual loss. Hypertension is also associated with obesity, which s correlated with other serious health risks as well. Although weight gain is associated with increased blood pressure, the mechanism by which excess fat deposits increase blood pressure remains unclear...

BACKGROUND: Many patients with depressive disorders demonstrate resistance to psychological therapy. A frequent finding is hypothalamic-pituitary-adrenal (HPA) axis alterations. As cortisol is known to modulate cognitive processes, those patients may be less likely to profit from psychological therapy. AIMS: To conduct a systematic review and meta-analysis on cortisol as a predictor of psychological therapy response. METHOD: The Cochrane Library, EMBASE, MEDLINE and PsycINFO databases were searched...

Acute stress stimulates corticotrophin-releasing hormone (CRH)-expressing neurons in the hypothalamic paraventricular nucleus (PVN), which is an essential component of hypothalamic-pituitary-adrenal (HPA) axis. However, the cellular and molecular mechanisms remain unclear. The M-channel is a voltage-dependent K(+) channel involved in stabilizing the neuronal membrane potential and regulating neuronal excitability. In this study, we tested our hypothesis that acute stress suppresses expression of Kv7 channels to stimulate PVN-CRH neurons and the HPA axis...

Cheetahs in managed zoological collections do not reproduce efficiently, a problem that may be related to environmental/management stressors. In this study, we examined 17 adult female cheetahs to determine the influence of two environmental factors, (1) being housed on- or off-exhibit and (2) number of adult conspecifics (males and/or females) in nearby enclosures, on profiles and concentrations of ovarian and adrenal hormones. Secondarily, we assessed a subset of group-housed siblings (n = 5 in groups of 2 or 3) for effects of long-term cohabitation...

BACKGROUND: With the use of intensive insulin therapy and insulin secretagogues to optimize glycemic control in diabetes, hypoglycemia continues to present a clinical challenge. Hypoglycemia has been implicated in nocturnal sudden death in type 1 diabetes, and the mechanism underlying this is postulated to be cardiac arrhythmia. OBJECTIVE: This article reviews the evidence surrounding hypoglycemia and cardiac arrhythmia. METHODS: A structured search of the Pubmed bibliographic database was undertaken, and relevant peer-reviewed articles on the topic were included in the review...

Long-term survivors of childhood acute lymphoblastic leukemia (ALL) are at risk for neurocognitive impairment, as well as compromised hypothalamic-pituitary-adrenal (HPA) function. Dehydroepiandrosterone-sulfate (DHEAS) is an adrenal androgen commonly used as a marker of HPA function. In the general population, a low level of DHEAS has been associated with poorer cognition. At ≥2years post-treatment, we examined the association of DHEAS with attention outcomes in 35 male and 34 female long-term survivors of childhood ALL (mean[standard deviation] age at evaluation 14...

Post-traumatic stress disorder (PTSD) is a chronic syndrome triggered by exposure to trauma and a failure to recover from a normal negative emotional reaction to traumatic stress. The neurobiology of PTSD and the participation of neuropeptides in the neural systems and circuits that control fear and anxiety are not fully understood. The long-term dysregulation of neuropeptide systems contributes to the development of anxiety disorders, including PTSD. The neuropeptide galanin (Gal) and its receptors participate in anxiety-like and depression-related behaviors via the modulation of neuroendocrine and monoaminergic systems...

PURPOSE OF REVIEW: The purpose is to review recent advances concerning the role of nuclear medicine in endocrine oncology. RECENT FINDINGS: For I therapy of thyroid cancer a thyrotropin (TSH) more than 30 mU/l has for many years been deemed a condition sine qua non. However, new data show that patients with lower TSH levels at the time of ablation have the same rate of successful ablation as those with TSH more than 30 mU/l.I-124 combined integrated positron emission tomography and computed X-ray tomography was shown to be highly accurate in predicting findings on posttherapy radioiodine scanning and was shown to have a high prognostic power...

ACTH is the primary regulator of adrenal glucocorticoid production. Elevated levels of ACTH play a critical role in disease progression in several indications including congenital adrenal hyperplasia and Cushing's disease. We have generated a specific, high affinity, neutralizing monoclonal antibody (ALD1613) to ACTH. In vitro, ALD1613 neutralizes ACTH-induced signaling via all five melanocortin receptors and inhibited ACTH-induced cAMP accumulation in a mouse adrenal cell line (Y1). ALD1613 administration to wild-type rats significantly reduced plasma corticosterone levels in a dose dependent manner...

CONTEXT: Loss-of-function mutations in the POMC gene are associated with the syndrome of adrenal insufficiency, obesity and red hair. We describe here a case of POMC deficiency, in which adrenal insufficiency was not treated until the fourth year of life. One of the disease-causative POMC mutations was characterized in vitro using a new approach. CASE DESCRIPTION: A boy presented in the first year of life with red hair, growth acceleration, moderate obesity and recurrent cholestasis, which was followed by two episodes of hypoglycemia at ages of 1...

BACKGROUND: Visceral venous aneurysms are exceedingly rare, and until now, there have been no reports of this phenomenon in the adrenal vasculature. This report details the first adrenal venous aneurysm reported in the literature. The aneurysm presented as an 18-cm mass that was initially suspected to be a hematoma or tumor on the basis of the complex medical history of the patient, which included hemophilia A and testicular cancer. After surgical excision, pathologic examination confirmed this mass to be a 15...

An impaired ability to sense and respond to drug-induced hypoglycemia is a common and serious complication in diabetic patients. The hypothalamic-pituitary-adrenal (HPA) axis activity plays a critical role in the counterregulatory response to hypoglycemia. We herein report a case that experienced restoration of a blunted HPA axis by avoiding hypoglycemia with the use of the DPP-4 inhibitor sitagliptin.

Mixed corticomedullary adrenal tumours (MCMT) are rare. We describe the second reported case of a male patient presenting with hypertension and Cushing syndrome with MCMT. A man aged 48 years presented with hypertension and signs of Cushing syndrome. 24-hour urine cortisol was elevated, with detectable adrenocorticotropic hormone (ACTH). A high-dose dexamethasone suppression test indicated an adrenal or ectopic Cushing syndrome. Plasma metanephrines were normal. A 3 cm left adrenal mass was identified without potential ectopic sources of ACTH on imaging...

Even under established replacement therapy, chronic adrenal insufficiency is associated with an impairment in daily life activities and a higher number of sick-days. In patients with individually adjusted glucocorticoid doses (avoiding over-replacement) the frequency of glucocorticoid side effects is low. Besides the standard treatment with conventional hydrocortisone, new formulas aiming at more adjusted physiological circadian cortisol profiles or improved individual dosing have been evaluated in recent clinical trials...

Paragangliomas are tumors that originate from the extra-adrenal chromaffin and nonchromaffin cells of neural crest origin. Lymph node metastases are common, while distant metastases to lung, liver, and bone are rare events and usually occur in the presence of a long standing clinically evident primary tumor. Primary diagnosis of paraganglioma at a metastatic site without a known primary is a diagnostic challenge. We report a case of an adult woman with incidentally detected metastasis to bilateral lungs from an occult carotid body paraganglioma, which presented a cytopathological diagnostic dilemma on EBUS-TBNA from paratracheal lymph nodes...

CONTEXT: Recurrence of hypercortisolism in patients after bilateral adrenalectomy for Cushing's disease is extremely rare. PATIENT: We present a rare case of a 27-year-old man who previously underwent bilateral adrenalectomy for Cushing's disease with complete clinical resolution. Cushingoid features recurred 12 years later, along with bilateral testicular enlargement. Hormonal tests confirmed ACTH-dependent Cushing's. Surgical resection of the testicular tumors led to clinical and biochemical remission...
