Objective: The present study examined the influence of light and dark, seasonal differences, electromagnetic fields, adrenergic and GABA-ergic control, age on melatonin secretion and also which factors affect rhythmicity of melatonin secretion, both in health and disease.Data were combined from a series of studies conducted between 1997 and 2006. Hormones were temporally assayed by immunometric assays.The results showed that melato...

Introduction: Adrenal hyperplasia is found in more than 15% of abdominal imaging procedures in adults, unrelated to endocrine disorders, especially after the COVID era. Adrenal management is consequently recommended.Aim: To retrospectively evaluate the adrenal status in terms of morphological progression and functional impairment of adrenal function, in a cohort of cases admitted at least yearly in the National Institute of Endocrinology, Bucharest, Roma...

Introduction: Delayed diagnosis of secondary hypertension, notably primary aldosteronism, challenges healthcare. Inconsistent guideline adherence hampers detection rates and diagnostic uniformity, emphasizing the imperative for improved diagnostic strategies in identifying primary hyperaldosteronism. Our study directly addresses this critical gap in clinical care, underscoring the need for enhanced diagnostics in patients undergoing investigation for secondary endocrine hypert...

Introduction: Assessment of adrenal insufficiency (AI) is done routinely through Synacthen test. However, the conventional high dose (250 μg) stimulation is supra-physiological, therefore 1 μg low dose test was developed.Aim: to investigate the utility of the Low-dose test vs the High-dose test, in patients with suspected central AI, in a tertiary centre of endocrinology, in the National Institute of Endocrinology, Bucharest, Romania.<p cla...

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...

The relationship between the level of genetic variation in CYP17, PSA genes and prostate cancer has been extensively studied but the results are still unclear. A 450c17a (CYP17) polymorphism A1/A2 was described to be significantly associated to prostate cancer. A SNP in the promotor PSA gene is an A to G substitution at position −158 (G158A) was proposed to interact differently with AR, thereby modifying the expression pattern and occurrence of prostate cancer.<p cla...

: A large number of studies are now focused on the causes of male infertility. Among these are epigenetic modifications, which are important contributors to reproductive pathology in the male by providing dynamic changes of the phenotype according to the environmental and metabolic factors. The most known epigenetic modification is DNA methylation and alterations in this pattern in several genes could induce male infertility. Alterations in DNA methylation patterns in several ...

The CDX2 VDR polymorphism (rs11568820) is located in the promoter region of exon 1 in the 5′-untranslated region of the VDR gene.Objective: The current investigation examines the association between CDX2 VDR polymorphism and male infertility.Subjects and methods: The study was conducted on 69 infertile men, aged between 20 and 50 years, divided into three groups, based on spermatic parameters: group with azoospermia (19 subje...

Introduction: Matrix metalloproteinase-9 (MMP-9) is a zinc dependent proteolytic enzyme used by cells for degradation of the extracellular matrix during invasion and migration. There are only a few reports regarding the role played by MMP-9 in papillary thyroid carcinoma (PTC).Aim: To evaluate the association between MMP-9 secretion, reflected by preoperative serum levels and the histopathological features of thyroid tumors.Materia...

Background: The role of circulating Galectin-3 as a potential biomarker of malignancy in thyroid disease remains inconclusive. In a previous pilot study we reported a significant difference between serum Gal-3 levels in papillary thyroid carcinoma (PTC) patients and those with benign pathology, but no association with tumor aggressiveness.Aim: We measured serum Gal-3 levels in a larger series of patients submitted to thyroidectomy, in order to assess its...
