Hyperprolactinemia is one of the most common problems in clinical endocrinology. It relates with various etiologies (physiological, pharmacological, pathological), the clarification of which requires careful history taking and clinical assessment.We present the case of a 15-year-old girl, with history of secondary amenorrhea and headache in the presence of mildly elevated prolactin level, diagnosed as a microprolactinoma on MRI scan (4–5 mm) and tr...

Background: Primary aldosteronism is associated with increased vascular mortality and morbidity.Aims: We aimed to assess metabolic and hormonal profile differences in patients with primary aldosteronism (PA) compared with patients with essential hypertension (EH).Patients and methods: Thirty-one patients (11 M/20 F) with primary aldosteronism, aged 46.2±12.9 years and 64 patients (24 M/40 F) with essential hypertension, aged 4...

Background: Cushing’s syndrome is represented by the cummulation of signs and symptoms of excess glucocorticoids and has many potential causes. Approximately 20 percent of all cases are represented by ACTH-independent adrenal tumors – with a majority of these being represented by cortisol secreting adrenal adenomas. Generally, a large adrenal tumor has over 5 cm in diameter and the risk of it being malignant raises proportionately with the dimensions. Large adrenal t...

Introduction: Excess GH in acromegaly has lipolytic action and detrimental effect on glucose metabolism and insulin signaling. Recent studies have suggested a specific lipodystrophy in patients with acromegaly. Paradoxically, although the visceral adipose tissue (VAT) and intrahepatic lipid were reduced in active acromegaly compared to controls, insulin resistance was increased. Fat was redistributed from subcutaneous and visceral depots to muscle; weight and VAT depots rose w...

Introduction: Acromegalic bone disease is characterized by an increased prevalence of fragility vertebral fractures (VFs). However, an effective, non-invasive and cost-efficient imaging technique that can diagnose early bone alterations in this category of patients is yet to found. The use of bone mineral density (BMD) is not as useful as in other causes of osteoporosis as excess GH leads to specific microarchitectural alteration of trabecular bone, which don’t translate ...

Primary hypophysitis is a rare inflammatory condition which is mostly encountered in women. It represents 0.2–0.8% of pituitary pathologies and its annual incidence is estimated at 1 case per 9 million inhabitants. We present the case of a 28-year-old male, smoker, with sudden onset decreased libido, polyuria and polydipsia. At presentation he had an epicranial lipoma with and no other suggestive clinical signs. Biochemistry revealed hypernatremia 146 nmol/L, low testoste...

Background: ER-α gene (ESR1) polymorphisms have been associated with a variety of disorders including human infertility. In this study, we examined two polymorphisms of the estrogen receptor α (ESR1) gene, IVS-1 −397 T/C (dbSNP: rs2234693) and IVS-1 −351 A/G (dbSNP: rs9340799) in a sample of healthy women of reproductive age to determine whether are associated with hormonal levels for a better understanding of its biological actions in human development, ...

Background: Acromegaly is characterized by increased prevalence of fragility vertebral fractures. Nonetheless, there are no clear recommendations for prevention of acromegalic osteopathy. Both bone mineral density (BMD) and trabecular bone score (TBS) lack clear evidence as prognostic factors for vertebral fractures (VF).Material and Methods: We performed an observational study on 31 acromegalic patients recruited prospectively. They were tested for alka...

Case presentation: Mrs. S presented in an endocrine clinic for fatigue, weight loss, restlessness and goiter. She was obese with a BMI of 51 kg/mp, hypertensive and had a medium size, nontender goiter. Lab test revealed hyperglycaemia, suppressed TSH (<0.03mUI/L), on two separate occasions, mid-normal fT4 and T3. Thyroid ultrasound revealed multinodular goiter. A diagnosis of polynodular goiter with subclinical hyperthyroidism was made and patient was commenced on thiamazo...

10% of patients with adrenal tumours have bilateral lesion.Objective: To evaluate clinical, imagistic and hormonal characteristics of bilateral adrenal tumours.Design and mehods: Retrospective series of 150 consecutive patients (104F, 46M) with bilateral adrenal tumours with maximal diameter of at least 1 cm, evaluated from 2001 to 2015 in a tertiary endocrinology clinic with clinical, hormonal and imagistic methods.<p class="a...
