: 1. OBJECTIVE: Gonadotropin-releasing hormone (GnRH) and Human Chorionic Gonadotropin (hCG) stimulation-tests may be used to evaluate the pituitary and testicular capacity. Our aim was to evaluate changes in follicular-stimulating hormone (FSH), luteinizing hormone (LH) and Testosterone after GnRH and hCG stimulation in healthy men, and assess the impact of six single nucleotide polymorphisms on the responses. 2. DESIGN: GnRH- and hCG-stimulation tests were performed on 77 healthy men, 18-40 years (reference group) at a specialized andrology referral center...

We present a case report of an atypical giant pituitary adenoma secreting follicle-stimulating hormone (FSH). A 55-year-old patient presented for erectile dysfunction, loss of libido and fatigue. The biochemical evaluation showed very high FSH serum levels in the presence of central hypogonadism. Neither testicular enlargement nor increased sperm count was observed, thus a secretion of FSH with reduced biological activity was supposed. The histological examination after neuro-surgery showed an atypical pituitary adenoma with FSH-positive cells...

BACKGROUND: In subclinical Cushing syndrome (SC), it is assumed that glucocorticoid production is insufficient to cause a clinically recognizable syndrome. Differences in hormonal levels or recovery time of the hypothalamic-pituitary-adrenocortical (HPA) axis after adrenalectomy between patients with overt Cushing syndrome (OC) and SC remain unknown. METHODS: Thirty-six patients (10 with OC and 26 with SC) with adrenal Cushing syndrome who underwent adrenalectomy from 2004 to 2014 were reviewed retrospectively...

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...

Turner syndrome (TS) is a genetic disorder in phenotypic females that has characteristic physical features and presents as partial or complete absence of the second sex chromosome. Growth hormone deficiency (GHD) is a condition caused by insufficient release of growth hormone from the pituitary gland. The concomitant occurrence of TS and GHD is rare and has not yet been reported in Korea. Here we report 2 cases of TS and GHD. In case 1, GHD was initially diagnosed. Karyotyping was performed because of the presence of the typical phenotype and poor response to growth hormone therapy, which revealed 45,X/45,X+mar...

Greater trochanteric pain syndrome (GTPS) is a common clinical entity for which the most effective treatment is local corticosteroid injection (LCI). There are no studies on the effect of LCI among patients with GTPS on the hypothalamic-pituitary-adrenal axis. The present study recruited nonselected patients diagnosed with GTPS. After consenting, participants received low dose (1 μg) of adrenocorticotropin hormone (ACTH) stimulation test at 09:00. Immediately following the test, participants received a LCI of 80 mg of methylprednisolone acetate at the greater trochanteric region...

Lhermitte-Duclos disease is a rare hamartomatous tumor of the cerebellum resulting from a mutation in the phosphatase and tensin homolog (PTEN) gene: it has been reported in fewer than 10 infants. Rapamycin treatment has not yet been described in Lhermitte-Duclos disease. The infant underwent shunt placement shortly after birth for aqueductal stenosis. Her clinical progression included failure to thrive, seizures, episodes of decerebrate posturing, loss of respiratory drive, and pituitary insufficiency from mass effect...

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...

Axenfeld-Rieger syndrome is a congenital disease with an estimated prevalence of one in 200,000 individuals. This is an ophthalmic disorder related to anterior segment dysgenesis, which may be present from the neonatal period. It is associated with extraocular affectations such as cranial dimorphism, maxillofacial or dental anomalies. Cardiological or pituitary manifestations are less common. The congenital heart disease in Axenfeld-Rieger syndrome has been described in very few cases in the literature. We report a 7-year-old patient with Axenfeld-Rieger syndrome and mild mitral insufficiency since the age of 3 years, which is progressing to moderate mitral regurgitation at the present time...

Stereotypies are used as indicators of poor animal welfare and it is, therefore, important to understand underlying factors mediating their development. In calves, two oral stereotypies, that is, tongue playing and object manipulation, result mostly from insufficient structure in the diet. Three hypotheses were studied: (1) oral stereotypies in calves are one of two alternative strategies, the alternative being hypo-activity; (2) stereotyping and non-stereotyping calves differ in terms of cortisol secretion; (3) oral stereotypy development in calves rests on a gene by environment interaction...

Steroid treatment is commonly recommended for autoimmune disorders in rheumatology practice. While adrenal crisis may occur upon existence of an inducing factor in patients with known or unknown adrenal insufficiency as well as in those with a suppressed hypothalamic-pituitary-adrenal (HPA) axis due to chronic steroid use, addisonian crisis rarely develops in patients on supraphysiological doses of steroid and, when emerged, it might be very difficult to recognize. Here, we present a patient who developed adrenal crisis while receiving high-dose methylprednisolone treatment due to retroperitoneal fibrosis and we also discuss possible mechanisms with a brief literature review...

BACKGROUND: Hypothalamic obesity is a devastating consequence of craniopharyngioma. Bariatric surgery could be a promising therapeutic option. However, its efficacy and safety in patients with craniopharyngioma-related hypothalamic obesity remain largely unknown. OBJECTIVES: We investigated the efficacy of bariatric surgery for inducing weight loss in patients with craniopharyngioma-related hypothalamic obesity. Additionally, we studied the safety of bariatric surgery regarding its effects on hormone replacement therapy for pituitary insufficiency...

OBJECTIVE Regrowth of the lesion after surgical removal of pituitary adenomas is uncommon unless subtotal resection was originally achieved in the first surgery. Treatment for recurrent tumor can involve surgery or radiotherapy. Locations of residual tumor may vary based on the original approach. The authors evaluated the specific sites of residual or recurrent tumor after different transsphenoidal approaches and describe the surgical outcome of endoscopic endonasal transsphenoidal reoperation. METHODS The authors analyzed a prospectively collected database of a consecutive series of patients who had undergone endoscopic endonasal surgeries for residual or recurrent pituitary adenomas after an original transsphenoidal microscopic or endoscopic surgery...

A 37-year-old female patient was hospitalized because of general fatigue and loss of axillary and pubic hair after massive bleeding at delivery of her third child. The basal levels of both plasma adrenocorticotropin hormone (ACTH) and serum cortisol were very low, 5.2 pg/mL and 1.9 μg/dL, respectively. Based on the fact that ACTH showed a low response to insulin tolerance test and a normal response to corticotropin-releasing hormone (CRH), she was diagnosed with hypothalamic adrenal insufficiency. No organic lesions were found in the hypothalamic-pituitary region by pituitary MRI and hydrocortisone therapy was instituted...

NAFLD is a common condition linked to obesity, type 2 diabetes, and metabolic syndrome. Simple hepatic steatosis is a risk factor for inflammatory reactions in the liver (NASH), which may lead to cirrhosis. While the mechanism is unclear, NAFLD and NASH are associated with panhypopituitarism, which in the pediatric population often results from craniopharyngioma or pituitary adenoma and the sequelae of treatment, causing hypothyroidism, adrenal insufficiency, hypogonadotropic hypogonadism, and GH deficiency...

Microbial metabolites are known to affect immune system, brain, and behavior via activation of pattern recognition receptors such as Toll-like receptor 4 (TLR4). Unlike the effect of the TLR4 agonist lipopolysaccharide (LPS), the role of other TLR agonists in immune-brain communication is insufficiently understood. We therefore hypothesized that the TLR2 agonist lipoteichoic acid (LTA) causes immune activation in the periphery and brain, stimulates the hypothalamic-pituitary-adrenal (HPA) axis and has an adverse effect on blood-brain barrier (BBB) and emotional behavior...

Aggressive behavior is not uniform, including proactive and reactive forms of aggression. Aberrant functioning of the hypothalamic-pituitary-adrenal (HPA) axis is frequently associated with abnormal aggression. Here, we review the rodent literature in order to assess whether developmental abnormalities in the HPA axis can be causally linked with the emergence of abnormal aggression. We examine studies that involve genetic models and life challenges (e.g., early life stress, drug exposure) that course with developmental alterations in the HPA axis...
