Introduction: Klinefelter syndrome (KS) is the most common genetic form of male hypogonadism, despite becoming evident only after puberty. The syndrome is characterized by a primary gonadal defect, which results in small testes due to hyalinization of the seminiferous tubules, low to low normal range of serum testosterone levels and elevated serum gonadotrophins. Paradoxically, a few cases have been described, presenting with hypogonadotropism.Case-repor...

Introduction: Glycemic variability (GV) is a major consideration when evaluating quality of glycemic control. Coefficient of glycemic variation (%CV) is the metric of choice to define GV. International consensus on continuous glucose monitoring (CGM) recommends a %CV <36. Additional studies suggest that low %CV minimize hypoglycemia events <54 mg/dl.Aims: The aim of this analysis is to examine the expected relationship between the coefficient of ...

Introduction: Prembrolizumab, a programmed cell death protein 1 (PD-1) inhibitor, is one of the immune checkpoint inhibitors (ICI) that have revolutionized cancer therapy. However, ICIs can also trigger immune-related adverse events (irAEs) in different organ systems, including endocrine glands. While thyroid dysfunction is among the most common endocrinopathies reported, ICI-induced diabetes mellitus (DM) is extremely rare, with an overall incidence ranging from 0.9 to 2%.</p...

X-linked adrenoleukodystrophy (X-ALD) is an inherited disorder of peroxisomal metabolism, characterized by deficient beta-oxidation of saturated very long chain fatty acids (VLCFA). The accumulation of VLCFAs is associated with demyelination of the nervous system, and impairment of steroid hormone synthesis in the adrenal cortex and the testis. The range of phenotypic expression is wide and dynamic. The three presentations most commonly seen are the childhood cerebral forms, a...

Introduction: Classic congenital adrenal hyperplasias (CAH) are mostly diagnosed in the first months/years of life and require a lifetime follow-up.Case report: A 33-year-old Caucasian man was admitted twice in the previous year to the emergency department; the first episode due to an acute tonsillitis, the second episode due to a lower respiratory tract infection, both associated with hyponatremia (125 mmol/l). Common causes of hyponatremia were exclude...

Introduction: Ectopic Cushing syndrome caused by a neuroendocrine tumor is uncommon and it’s diagnosis is often delayed. Optic neuritis is another rare disease, with some cases also associated to neuroendocrine tumors.Case-report: A 43-year-old female was referred to the endocrinology outpatient’s department due to obesity. She had a past history of bilateral optic neuritis of unknown etiology. She complained of weight gain, hair loss, acne, hi...

False elevation of estradiol(E2) due to immunoassay interference is a rare but important phenomenon reported in the literature. It is most commonly related to cross-reactivity(CR) from drugs sharing structural similarity with E2, namely fulvestrant and exemestane. These laboratory interferences(LI) can lead to unnecessary investigation/inappropriate treatments. Therefore, in such instances, a more selective and sensitive method is required. We present the case of a young femal...

Background and aims: It is known that unilateral adrenalectomy as treatment for autonomous secreting adrenal cortex adenomas effectively reduces cardiometabolic risk. Non-autonomous secreting adenomas are not expected to increase cardiometabolic risk, but this has not been thoroughly explored.We evaluated the blood pressure and glycemic profile before and after unilateral adrenalectomy for both autonomous and non-autonomous secreting adrenal cortex adenomas.<p class="abste...

Introduction: The use of Continuous Subcutaneous Insulin Infusion (CSII) is expected to improve glycemic control and to reduce hypoglycemia events. However, long-term beneficial results in glucose control are not always observed. We evaluated long-time glucose control and severe hypoglycemias in type 1 diabetic patients using CSII, without continuous glucose monitoring.Patients and methods: This was a retrospective study of adult type 1 diabetic patients...

Introduction: Nonfunctioning pituitary adenomas (NFPAs) are a heterogeneous group of tumors with different presentations. Clinical management of these tumors is complex. Our aim was to evaluate the clinical characteristics/postsurgical outcomes of NFPAs and to identify predictive factors of good response to surgery.Methods: Retrospective analysis of NFPA, who underwent surgery and followed in our hospital, from 2015-2022.Results: W...
