Clinicopathological significance of baseline T2-weighted signal intensity in functional pituitary adenomas
AbstractPurposeTo assess baseline T2-weighted signal intensity (T2-WSI) of functional pituitary adenomas (FPA), and to investigate the relationship of baseline T2-WSI with clinical features, histopathological granulation patterns, and response to treatment in patients with acromegaly, prolactinoma and Cushing ’s disease (CD).MethodsSomatotroph adenomas (n = 87), prolactinomas (n = 78) and corticotroph adenomas (n = 29) were included in the study. Baseline T2-WSI findings (grouped as hypo-, iso- and hyperintense) were compared with hormone levels, tumor diameter, granulation ...

CyberKnife robotic radiosurgery in the multimodal management of acromegaly patients with invasive macroadenoma: a single center ’s experience
AbstractSurgery is the primary treatment for acromegaly. However, surgery may not be curative of some tumors, particularly invasive macroadenomas. Adjuvant radiation, specifically robotic stereotactic radiosurgery (rSRS), may improve the endocrine outcome. We retrospectively reviewed hormonal and radiological data of 22 acromegalic patients with invasive macroadenomas treated with rSRS at Stanford University Medical Center between 2000 and 2016. Prior to treatment, the tumor ’s median maximal diameter was 19 mm (2.5–50 mm). Cavernous sinus invasion occurred in 19 patients (86.3%) and compression of th...

Factors affecting early versus late remission in acromegaly following stereotactic radiosurgery
This study aims to identify factors affecting the timing of remission and also to quantify the rate of late remission. This is a retrospective analysis of acromegaly patients who underwent SRS between 1988 and 2016. Early and late remissions were defined based on our prior median remission time of 29 months. The median imaging and endocrine follow-ups are 66 and 104.8 months, respectively. Multivariate analysis was conducted to analyze factors leading to late remission.

Female gonadal functions and ovarian reserve in patients with acromegaly: experience from a single tertiary center
ConclusionThe most important factors affecting gonadal functions, excluding central hypogonadism, are hyperprolactinemia and the duration of the indolent period before diagnosis of acromegaly. AMH levels in the majority of patients were found to be lower than the expected age. Despite the decreased ovarian reserve, fertilization and normal birth can be achieved with careful surveillance.

MANAGEMENT OF ENDOCRINE DISEASE: Personalized medicine in the treatment of acromegaly.
Abstract Acromegaly is associated with high morbidity and elevated mortality when not adequately treated. Surgery is the first-line treatment for most patients as it is the only one that can lead to immediate cure. In patients who are not cured by surgery, treatment is currently based on a trial-and-error approach. First-generation somatostatin receptor ligands (fg-SRL) are initiated for most patients, although approximately 25% of patients present resistance to this drug class. Some biomarkers of treatment outcome are described in the literature, with the aim of categorizing patients into different groups to indi...

Cant ú syndrome with coexisting familial pituitary adenoma
ConclusionsActivating mutations in theABCC9 and, less commonly,KCNJ8 genes —representing the two subunits of the ATP-sensitive potassium channel—have been linked with Cantú syndrome. Interestingly, minoxidil, a well-known ATP-sensitive potassium channel agonist, can cause a similar phenotype. There is no clear explanation why activating this channel would lead to acro megaloid features or hypertrichosis. This report raises awareness for this complex condition, especially for adult or pediatric endocrinologists who might see these patients referred for evaluation of acromegaloid features or hirsutism.

Silent somatotroph pituitary adenomas: an update
AbstractSilent growth hormone adenomas (SGHA) are a rare entity of non-functioning pituitary neuroendocrine tumors. Diagnosis is invariably made post-operatively of a tumor immunopositive for GH (and Pit-1 in selected cases) but without clinical acromegaly. Mainly young females are affected, and tumors are often uncovered by investigation for headaches or oligoamenorrhea. Integration of clinical, pathological and biochemical data is required for proper diagnosis. Beside normal IGF-1 levels, a third of SGHAs displays elevated GH levels and some will eventually progress to acromegaly. Almost two-thirds will be mixed GH-prola...

Bone histological correlates for air sacs and their implications for understanding the origin of the dinosaurian respiratory system.
Abstract Air sacs are an important component of the avian respiratory system, and corresponding structures also were crucial for the evolution of sauropod dinosaur gigantism. Inferring the presence of air sacs in fossils so far is restricted to bones preserving internal pneumatic cavities and foramina as osteological correlates. We here present bone histological correlates for air sacs as a new potential identification tool for these elements of the respiratory system. The analysis of several avian and non-avian dinosaur samples revealed delicate fibres in secondary trabecular and secondary endosteal bone that in ...

Severe prostate enlargement with severe lower urinary tract symptoms in poorly controlled acromegaly successfully treated with 5 α‐reductase inhibitors: A 15‐year longitudinal case report
Acromegaly is a rare disease associated with an increased risk of prostate enlargement. Severe prostate enlargement with severe lower urinary tract symptoms (LUTS) in an acromegalic patient is even more uncommon. Herein we report on a 55‐year‐old man who was diagnosed with acromegaly and prostate enlargement at 40 years of age. Transsphenoidal surgery, postoperative radiotherapy, and octreotide medical therapy failed to control the acromegaly, and growth hormone (GH) and insulin‐like growth factor 1 (IGF‐1) levels remained elevated. When the patient was 53 years of age, severe LUTS and prostate enlarg...

Association between dopamine and somatostatin receptor expression and pharmacological response to somatostatin analogues in acromegaly.

Elevated GH and IGF-I levels result in a wide range of somatic, cardiovascular, endocrine, metabolic and gastrointestinal morbidities. Somatostatin analogues (SSAs) form the basis of medical therapy for acromegaly and are currently used as first-line treatment or as second-line therapy in patients undergoing unsuccessful surgery. However, a considerable percentage of patients do not respond to S...

Bone histomorphometry in acromegaly patients with fragility vertebral fractures
ConclusionsThe apparent paradox of bone fragility in acromegaly patients with a normal BMD can be explained by increased cortical thickness and porosity and reduced trabecular thickness with increased trabecular separation. These structural and microarchitectural abnormalities persist in the controlled phase of acromegaly despite bone turnover normalization. The main determinant of bone disease after hormonal control is severe osteoblastic dysfunction. (Source: Pituitary)
