Introduction: Mitotane is widely used to treat adrenocortical carcinoma (ACC) and remains the mainstay of treatment along with surgery. The aim of this study is to evaluate the adverse side effects of mitotane treatment.Materials and Methods: This retrospective study included 36 patients with ACC, ENSAT stage I- IV, who were treated with mitotane in an adjuvant or palliative setting. Patients with ENSAT stage IV who died within 6 months after surgery wer...

Recognizing the site of origin of craniopharyngioma (CP) along the hypothalamus-pituitary axis according to pre-operative MR is helpful to understand its growth pattern in relation to hypothalamus, which is critical in the prediction of hypothalamic injury and planning of treatment. We retrospectively classified 29 CP according to MR pre-operative image study using modified classification of Tang et al. (Nature, 8:10215, 2018). According to its relation to pituitary s...

Background: The aim of this study was to evaluate the outcomes of medical treatment in patients with active acromegaly.Material and Methods: We performed a retrospective analysis of 163 patients (101 female, age at diagnosis 47.2±13.4 years) treated between 1990 and 2020., of which 53 were on medical treatment (32.5%). Remission rate after pituitary surgery was 66.5% (n=105/158; 5 patients refused surgery). Patients who did not achieve remiss...

Background: Non-functioning pituitary adenomas (NFPA) account for 30-35% of pituitary adenomas. They can lead to hypopituitarism and visual field defects. Trans-sphenoidal resection of pituitary adenoma remains the treatment of choice.Methods: We compared clinical, biochemical, and imaging characteristics of NFPAs at presentation with post-surgical outcomes in a retrospective cohort study. Patients who underwent end...

Background: Immunotherapy mediated adrenocorticotrpic hormone (ACTH) deficiency is an important toxicity related to immune-checkpoint inhibitors (ICPi) potentially resulting in significant morbidity. Early diagnosis and optimal management are essential and frequently necessitate inpatient hospital treatment. We have previously reported an ambulatory management pathway for ICPi-induced ACTH deficiency in 4 patients. We sought to report the outcomes of this pathway in a larger c...

Introduction: Pachydermoperiostosis (primary hypertrophic osteoarthropathy, PHOA) is a rare genetic condition characterised by digital clubbing, pachydermia, hyperhidrosis, cutis verticis gyrata and periostosis. The SLCO2A1 transporter and HPGD enzyme genes play an important role in prostaglandin metabolism, hence loss of function mutations in them causes PHOA. To date, according to the VarSome database 101 and 41 variants have been identified in the SLCO...

Introduction: Transgender women on gender-affirming hormone therapy (GAHT) with estrogens and anti-androgens have low serum androgen levels. These low levels may be associated with clinical symptoms such as depressed mood, reduced sexual desire and tiredness. Whether androgen levels change over the course of anti-androgen use and after gonadectomy, in a context of unchanged estrogen treatment, remains to be elucidated.Methods: This study is part of the E...

Purpose: To evaluate the value of early postoperative growth hormone (GH) as a predictor of surgical remission of acromegaly.Methods: We conducted a retrospective search through our database of patients who underwent transsphenoidal surgery for GH-secreting pituitary adenoma from 2011 to June 2022. Only patients who underwent the first pituitary surgery and had GH measurements on the fifth postoperative day were included. The surgical remission was defin...

Background: Men with obesity often have low total and, with increasing adiposity, also free testosterone (T) levels, which can partially restore when they lose weight. Although this is in part explained by lower sex-hormone binding globulin (SHBG) production and hypothalamic-pituitary downregulation, it is still not fully unraveled whether changes in androgen metabolization contribute to this phenomenon.Aim: Investigating metabolisation of sex steroids d...
