Nonclassic congenital adrenal hyperplasia (NCAH) is an autosomal-recessive disorder caused by 21-hydroxylase deficiency and manifests as hirsutism and oligomenorrhea due to excess adrenal androgen and progesterone. We report a case of a woman with NCAH who showed continuous high serum progesterone levels in the follicular phase associated with impaired folliculogenesis. NCAH was diagnosed based on high 17-hydroxyprogesterone levels after rapid adrenocorticotropic hormone loading, and three heterozygous missense mutations in CYP21A2, encoding 21-hydroxylase, were identified...

Endogenous hypercortisolism (Cushing syndrome) usually implies the presence of a pathologic condition caused by either an ACTH-secreting neoplasm or autonomous cortisol secretion from a benign or malignant adrenal neoplasm. However, sustained or intermittent hypercortisolism may also accompany many medical disorders that stimulate physiologic/non-neoplastic activation of the HPA axis (formerly known as pseudo-Cushing syndrome); these two entities may share indistinguishable clinical and biochemical features...

BACKGROUND: The crucial role of the hypothalamic-pituitary-adrenal axis (HPA) in stress-related homeostasis suggests dysregulated HPA involvement in the pathogenesis of post-traumatic stress disorder (PTSD), yet most studies examining linkages between HPA axis measures and PTSD have yielded null findings. One untested explanation for this inconsistency is a failure to account for simultaneous adrenal and gonadal influence. Here we tested the singular and interactive effects of cortisol (CR) and testosterone (TR) reactivity as moderators of war-zone stress evoked PTSD emergence in the war-zone...

The regulation of mRNA stability has emerged as a critical control step in dynamic gene expression. This process occurs in response to modifications of the cellular environment, including hormonal variations, and regulates the expression of subsets of proteins whose levels need to be rapidly adjusted. Modulation of messenger RNA stability is usually mediated by stabilizing or destabilizing RNA-binding proteins (RNA-BP) that bind to the 3'-untranslated region regulatory motifs, such as AU-rich elements (AREs)...

When a patient receiving anti-cancer treatment presents acutely unwell, an understanding of associated side effects of their therapy is critical. This review will discuss the approach to patients receiving anti-cancer treatment with immunotherapy presenting with autoimmune toxicities in the emergency setting. These toxicities are commonly referred to as immune-related adverse events (irAE). IrAE might consist of, but are not limited to, dermatologic, gastrointestinal (diarrhoea, colitis), hepatic, endocrine (thyroid dysfunction, hypophysitis, adrenal crisis), renal, ocular and pulmonary toxicity...

Primary adrenal lymphomas (PAL) are rare occurrences with only less than 150 cases reported in the literature. Two-thirds of these cases were reported in the last decade due to the advancements in imaging techniques and immunohistochemistry. The non-specific signs and symptoms have resulted in a delayed onset of symptoms and diagnosis of these tumors. Reports of the results of chemotherapy are not gratifying, and most patients die within one year of the diagnosis. We report a 65-year-old male with adrenal non-Hodgkin's lymphoma (NHL), who presented with hypercalcemia and renal failure...

The renin-angiotensin system (RAS) is one of important systems among homeostatic mechanisms that control the function of cardiovascular, renal and adrenal systems. As RAS has a very complex nature, it has been also found as related to the control of cell migration and apoptosis. Angiotensin-converting enzyme inhibitors (ACEI) are drugs most commonly used in the modulation of RAS activity. ACEI have been extensively described as effective in the treatment of hypertension among adults, but also as drugs delaying progression in diabetic nephropathy and reducing mortality in left ventricular dysfunction and congestive heart failure...

INTRODUCTION: It is rare for a patient to present with adrenal insufficiency secondary to bilateral adrenal metastases from a malignant colorectal tumor. CASE PRESENTATION: An 82-year-old Japanese man presented to our hospital with high fever and malaise. He was receiving oral chemotherapy for the treatment of rectal cancer with multiple metastases. Computed tomography showed new bilateral adrenal gland metastases. A rapid adrenocorticotropic hormone (ACTH) test showed adrenal insufficiency...

Glucocorticoid hormones (GCs) released from the fetal/maternal glands during late gestation are required for normal development of mammalian organs and tissues. Accordingly, synthetic glucocorticoids have proven to be invaluable in perinatal medicine where they are widely used to accelerate fetal lung maturation when there is risk of pre-term birth and to promote infant survival. However, clinical and pre-clinical studies have demonstrated that inappropriate exposure of the developing brain to elevated levels of GCs, either as a result of clinical over-use or after stress-induced activation of the fetal/maternal adrenal cortex, is linked with significant effects on brain structure, neurological function and behaviour in later life...

The validation of laboratory paradigms that reliably induce a stress response [including hypothalamic-pituitary-adrenal (HPA) axis and autonomic nervous system (ANS) activation], is critical for understanding how children's stress-response systems support emotional and cognitive function. Early childhood research to date is markedly limited, given the difficulty in establishing paradigms that reliably induce a cortisol response. Furthermore, research to date has not included a control condition or examined concurrent ANS reactivity...

Hypopituitarism is a clinically important diagnosis and has not previously been reported in Hunter syndrome. We contrast two cases with anatomic pituitary anomalies: one with anterior panhypopituitarism and the other with intact pituitary function. Patient 1, a 10-year-old boy with Hunter syndrome, was evaluated for poor growth and an ectopic posterior pituitary gland. Endocrine testing revealed growth hormone (GH) deficiency, secondary adrenal insufficiency, and tertiary hypothyroidism. An improvement in growth velocity with hormone replacement (GH, thyroxine, and corticosteroid) was seen; however, final adult height remained compromised...

B-type natriuretic peptide (BNP) is a hormone released by the heart in response to volume load and exerts natriuretic properties. It is clinically used as a diagnostic and prognostic biomarker, and investigated as a pharmacological agent in the therapy of heart failure. Here we investigate the changes in pituitary, adrenal and thyroid hormones in response to BNP administration in a randomized single-blinded cross-over study conducted in ten healthy men aged 21-29 years. Participants received in two study sessions a continuous intravenous infusion during four hours (once placebo and once three pmol/kg/min BNP) and remained in supine position throughout the study...

Sheehan syndrome or postpartum hypopituitarism is a condition characterized by hypopituitarism due to necrosis of the pituitary gland. The initial insult is caused by massive postpartum haemorrhage (PPH), leading to impaired blood supply to the pituitary gland, which has become enlarged during pregnancy. Small sella turcica size, vasospasms (caused by PPH) and/or thrombosis (associated with pregnancy or coagulation disorders) are predisposing factors; autoimmunity might be involved in the progressive worsening of pituitary functions...

Aldosterone is the most known mineralocorticoid hormone synthesized by the adrenal cortex. The genomic pathway displayed by aldosterone is attributed to the mineralocorticoid receptor (MR) signaling. Even though the rapid effects displayed by aldosterone are long known, our knowledge regarding the receptor responsible for such event is still poor. It is intense that the debate whether the MR or another receptor-the "unknown receptor"-is the receptor responsible for the rapid effects of aldosterone. Recently, G protein-coupled estrogen receptor-1 (GPER-1) was elegantly shown to mediate some aldosterone-induced rapid effects in several tissues, a fact that strongly places GPER-1 as the unknown receptor...

De novo hepatitis B is associated with a high risk of hepatic failure often resulting in fatal fulminant hepatitis even when nucleotide analogues are administered. A 77-year-old female developed de novo hepatitis B after R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone) treatment for diffuse large B-cell lymphoma. Hepatitis B virus (HBV) isolated from the patient was of genotype Bj, with a precore mutation (G1896A) exhibiting an extremely high viral load at the onset of hepatitis...

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...

BACKGROUND: Pheochromocytoma, a rare catecholamine-producing tumor, might provoke stress-induced Takotsubo-like cardiomyopathy and severe cardiogenic shock. Because venoarterial-extracorporeal membrane oxygenation (VA-ECMO) rescue of pheochromocytoma-induced refractory cardiogenic shock has rarely been reported, we reviewed our ICU patients' presentations and outcomes. METHODS: All pheochromocytoma-induced refractory cardiogenic shock cases managed with VA-ECMO (January 2007-March 2015) were prospectively included and reviewed...

A four-year-old previously well boy collapsed unexpectedly and was taken immediately to hospital, where he developed seizures and cardiogenic shock with lethal, rapidly progressing multi-organ failure. At autopsy, the height was >90th percentile and there were indications of early virilization. Internally, a friable tumor of the left adrenal gland was identified that had invaded the left renal vein and inferior vena cava. Histology revealed typical features of an adrenocortical carcinoma with aggregated trabeculae of cells containing abundant eosinophilic cytoplasm and large pleomorphic nuclei...
