Background: The majority of adrenocorticotropic hormone (ACTH)-secreting pituitary adenomas are less than 10 mm in diameter and are described as microadenomas, while corticotroph macroadenomas (≥10 mm) are a less common cause of Cushing’s disease. Prior reports on the differences of clinical and biochemical behavior of corticotroph microadenomas and macroadenomas were inconsistent.Objective: Describe the clinical and biochemical characteristic...

Background: Adrenocorticotropic hormone (ACTH)-producing pituitary adenoma is the most common cause of endogenous Cushing syndrome (CS), but the relative proportion of adrenal causes of CS is rising. Limited data are available on the clinical manifestations and cause of CS in older women.Objective: Determine the clinical presentation, biochemical profile, and cause of CS in women 65 years of age and older, compared with younger patients with CS.<p cl...

Introduction: Pregnancy and lactation-associated osteoporosis (PLO) is a rare condition in which women have fragile fractures associated with significant reduction of BMD during pregnancy or postpartum period.Case report: A 37-year-old female patient was admitted at our Clinic for further investigation of aetiology of osteoporosis in July 2019. Soon after delivery in February 2019 patient had felt left hip and foot pain as well as sharp intensive pain (i...

Introduction: Diabetes is the leading worldwide cause of chronic kidney disease, which is diagnosed by measuring albuminuria and estimating glomerular filtration rate (GFR) with creatinine-based formulas, such as the 2009 CKD-EPI developed in the United States of America (USA). Nonetheless, the race coefficient (RC), present in the 2009 CKD-EPI, may overestimate GFR in other countries.Aim: The goal of this systematic review and meta-analysis was to asses...

Background: Autonomic hyperfunctioning thyroid nodules account for approximately 5% to 10% of all thyroid nodules. Compared with non-toxic nodules, hot nodules are traditionally believed to have an exceptionally low malignancy rate, and this has led to recommendations not to perform fine-needle aspiration (FNA) on these lesions, regardless of their size. However, recent studies have questioned the presumed low risk of malignancy in hot nodules, suggesting that the incidence of...

Introduction: Pheochromocytoma is an adrenal medullary tumor which typically involves nonspecific symptoms like arterial blood hypertension, tachycardia, headache or sweating. In some cases, patients may be completely asymptomatic at onset and exceptionally develop symptoms after surgery.Case presentation: We present two cases, first one of a 36 years old male, in which an MRI scan for evaluation of the spine revealed an oval, well-contoured heterogeneou...

Autosomal dominant hypoparathyroidism (ADH) is caused by gain-of-function mutations in the calcium-sensing receptor (CaSR), increasing its sensitivity to extracellular calcium, suppressing PTH and resulting in hypocalcaemia. In contrast to idiopathic hypoparathyroidism, treatment to correct serum calcium results in high urine calcium excretion, causing nephrocalcinosis, stones and renal impairment. Unlike surgical hypoparathyroidism where calcium should be maintained, patients...

Objective: The aim of this study was to investigate sex-specific associations of two established serum selenium biomarkers, i.e. total selenium and selenoprotein P with type 2 diabetes mellitus (T2D) and hypertension in a large cohort of older people.Methods: 1500 participants with available selenium measurements from the Berlin Aging Study II (BASE-II) were included in this study. In the serum samples, spectroscopy was used to quantify total selenium, a...

Background: PET/CT scan with 18F-fluoro-dihydroxyphenylalanine (18F–DOPA) is an emerging useful tool in medullary thyroid cancer (MTC) patients with high calcitonin (CTN) values. The aim of this study is to evaluate the potential usefulness of 18F-DOPA-PET/CT in MTC patients with biochemical incomplete response (BiR) (detectable CTN values and negative/indeterminate findings at CT scan with i.v. contrast).Materials a...

Background: Metabolic syndrome (MetS) is a clustering of metabolic and cardiovascular risk factors, with insulin resistance being one of the main components. In male, MetS is also associated to hypogonadotropic hypogonadism. Lifestyle modifications (e.g. physical activity) could prevent or considerably reduce MetS progression, however the ability to perform physical activity is often impaired in MetS subjects.Aim: Considering the known trophic role of T ...
