Introduction: Cardiovascular changes are rare but life-threatening consequences of primary hyperparathyroidism.Case report: A 53-year-old man, with past and family history of peptic ulcer, presenting with coronary heart disease and ischemic and dilated cardiomyopathy, treated with cardiac resynchronization. He was admitted to the emergency room due to sustained monomorphic ventricular tachycardia (MVT). Laboratory tests revealed primary hyperparathyroidi...

Background: Hypomagnesemia is common in patients with diabetes; possibly due to higher renal magnesium excretion in those patients. Hypomagnesemia seems to correlate with poor glycaemic control. The relationship between urinary magnesium (UMg) and glycaemic control is not known. We aimed to study the association between UMg and glycaemic control in a type 1 diabetes (T1D) pediatric population.Methods: Study of a pediatric population with T1D attending th...

Introduction: Cushing’s Disease results of corticotrophin (ACTH) hypersecretion from pituitary which increases cortisol production. WHO classified pituitary tumors as typical adenoma, atypical adenoma and carcinoma. Diagnostic criteria for an atypical adenoma include invasive growth, elevated mitotic index, Ki-67 labeling index greater than 3% and extensive p53 immunoreactivity.Case Report: Sixty-eight years-old man presented to our consult with his...

Introduction: Monosomy 18q represents a partial deletion of the long arm of chromosome 18, with an estimated prevalence of 1:100 000. This syndrome is characterized by a highly variable phenotype. The symptoms and their severity depend on which part of the chromosome is missing. Most common manifestations are hypotonia, developmental delay, short stature, growth hormone deficiency, hearing loss and external ear anomalies, intellectual disability, palatal defects, dysmorphic fa...

Introduction: Current guidelines recommend a single prolactin sampling for the diagnosis of hyperprolactinaemia. Nonetheless, in some patients, prolactin levels may normalize in a subsequent sampling or if prolactin is collected through a venous catheter some time after puncture. We aimed to assess the percentage of patients in which prolactin remained elevated in repeated sampling and to determine the best prolactin cutoff associated with persistent hyperprolactinaemia.<p...

Introduction: Central diabetes insipidus (DI) is a frequent complication of transfenoidal surgery for Cushing’s disease (CD). It can be transient or, more infrequently, permanent. The most common mechanism results from surgical neurohypophyseal damage rather than local mass effect from the pituitary adenoma.Case report: A 40 years old woman was referred to our Endocrinology outpatient clinic at the beginning of 2015 for new onset hypertension, signi...

Introduction: Alemtuzumab is a humanized anti-CD52 monoclonal antibody approved for the treatment of relapsing−remitting multiple sclerosis (RRMS). Through an immune reconstitution mechanism, it leads to thyroid autoimmunity in 35% of cases, with Graves’ disease (GD) being the most common presentation. Alemtuzumab-induced GD exhibits distinctive clinical and immunological features, with rarely reported cases of fluctuating thyroid status with documented both blockin...

Cushing’s syndrome (CS) is associated with a considerable risk of complications including thromboembolic events (TE). They occur mostly within the first 2–3 months postoperatively. When present before surgery, CS has high rates of perioperative mortality and morbidity. The benefit of steroidogenesis inhibitors after TE is not fully known. Furthermore, little guidance is available regarding TE assessment/management in CS. We report a case of a 34-year-old male admitte...

Introduction: The treatment of Primary Adrenal Insufficiency involves the chronic use of glucocorticoids. The balance between the dose needed to supply the cortisol deficit and the possible consequences of overtreatment is a challenge. In patients with Addison disease (AD), androgens deficiency is an additional factor for osteoporosis.Objective: To evaluate if there are differences in bone mineral density (BMD) in patients with Addison’s disease ver...

Introduction: The effects of long-term replacement therapy of primary adrenal insufficiency (PAI) are still a matter of debate. Glucocorticoid (GC) replacement regimens do not completely mimic the endogenous hormonal production and their monitoring is sometimes difficult. Therefore, some patients are exposed to mild GC excess with potential complications, such as hypertension, diabetes, and skeletal fragility. Data on bone mineral density (BMD) in PAI is still scarce and contr...
