Introduction: Secondary hormonal deficiencies (SHD) are frequently observed in patients with pituitary adenomas. We previously reported that pituitary tumour clinical subtypes were associated with specific patterns of SHD, and nonfunctioning adenomas (NFAs) were more likely to present with multiple SHD. We extended our work to examine if the immunohistochemical staining patterns of NFAs impacted SHD.Methods: All clinically NFAs surgically removed between...

Patients with sellar masses (SM) undergoing transsphenoidal surgery (TSS) have a significant risk of transient or permanent endocrine dysfunction; therefore, in-hospital endocrinology consultation (IHEC) is recommended for these patients. However, routine assessment of all TSS patients by a specialized team is not feasible outside select centers. We developed an IHEC guide for TSS patients in December 2015 to identify those patients who would require perioperative IHEC. We con...

Introduction: While there is a significant risk of recurrence in nonfunctioning pituitary adenoma (NFPA) after surgery, it is challenging to predict which NFPAs will recur based solely on routine histopathology. To better understand markers of recurrence, we assessed the established tumor markers linked to aggressive tumor behavior including X-linked IAP (XIAP), the most potent inhibitor of the apoptosis protein family, vascular epithelial growth factor (VEGF) which facilitate...

Patients with acromegaly (PWA) experience higher rates of falls and fall-related injuries than age-matched Canadian adults. Previous studies of standing balance revealed increased sway in PWA compared to healthy controls but failed to control for the effects of the pituitary adenoma. Therefore, the aim of the present study was to determine if acromegaly influenced the neuromuscular control of standing balance. Bipedal standing balance was evaluated in PWA (n=13) in bi...

Acromegaly triggers, and is associated with, peripheral nervous system modifications and joint degenerations, which are considered to impact the walking balance of patients with acromegaly (PWA). Therefore, to better understand if these systemic degenerations impact the transitory adaptations in locomotor patterns of these patients, this study aims to establish the walking balance deficits of PWA. Walking balance was evaluated in PWA (n=8) in biochemical remission and...

Acromegaly, characterized by growth hormone excess, adversely affects the patients’ musculoskeletal and neural systems, consequently impairing physical function. Previous studies have noted walking impairments in patients with acromegaly (PWA). This study aimed to characterize the kinematic and kinetic changes during walking in PWA. Kinematics and kinetics of walking were evaluated in PWA (n=8) in biochemical remission and a control group of patients with non-fun...

Secondary hormonal deficiency (SHD) is common in patients presenting with nonfunctioning pituitary adenomas (NFA). NFA can either stain for various hormones or be non-hormone staining on immunocytochemistry. To date, no study has assessed the association between staining pattern of NFA and pattern of SHD at presentation. The Halifax Neuropituitary Program has been prospectively collecting comprehensive data on all neuropituitary patients in the province of Nova Scotia, Canada ...

Background: Acromegaly (Acro) is associated with adverse psychopathological and personality outcomes despite being in remission for over a decade. We hypothesised that persistently poor psychological outcomes may be associated with morphometric changes experienced by Acro patients.Methodology: We compared 60 consecutive non-functioning adenoma (NFA) and Acro patients who had undergone pituitary surgery and/or radiation therapy (RT). A gender-specific vis...

We recently developed a visual scale to assess the extent of morphometric changes in Acromegaly (Acro) patients which is strongly predictive of adverse psychological outcomes. We sought to identify if there was any association between the self-drawing test and the visual morphometric scale and if there was any correlation with psychological outcomes.We compared 60 consecutive non-functioning adenoma (NFA) and Acro patients who had undergone pituitary sur...
