Abdominal surgery and diseases such as endometriosis cause persistent abdominal adhesions leading to pelvic pain, infertility and in severe cases, bowel obstruction. Current treatments are ineffective and the aetiology is unclear, although excessive collagen deposition is a consistent feature. Lysyl oxidase (LOX) is a key enzyme required for crosslinking and deposition of insoluble collagen.10–12 weeks old female C57Bl/6 mice (3–10 mice per gro...

Silent pituitary adenomas are defined as a group of adenomas that are hormonally inactive and do not show clinical signs and symptoms of excess hormones. Data in the literature indicate that fertility is usually affected in women with silent pituitary adenomas.Aim: To investigate the possible effects of silent pituitary adenomas on pregnancy.Patients and method: Thirty patients followed by silent pituitary adenoma, without hormone ...

Transphobia is expressed as negative attitudes, emotions and actions towards transgender individuals or transsexualism. The aim of this study is to investigate the existence of transphobic approaches towards transgender individuals in physicians in different clinics that play an active role in the gender transition process. It was planned to include physicians from the disciplines of psychiatry, endocrinology, gynecology, urology and plastic surgery. A questionnaire was sent t...

Introduction: Congenital Adrenal Hyperplasia (CAH) results from enzymatic defects caused by autossomal recessive hereditary mutations characterized by deficient cortisol synthesis and, in most cases, increased androgen synthesis. 90–95% of the cases are originated by deficits in 21-hydroxylase and, in about 75% of the cases, there is evidence of mineralocorticoid deficiency.Case report: A 37-year-old patient was referred to an Endocrinology departm...

Introduction: Acromegaly is a chronic disease caused by excess growth hormone (GH) release from an adenoma caused by somatotroph cells of pituitary gland.In acromegaly, it is known that the risk of thyroid and colon cancer is increased 8 and 4 times, respectively, compared to the normal population.Moderate hypercalcemia, due to vitaminD activation, is seen in acromegaly, but overt hypercalcemia, generally secondary to primary hyperparathyroidism, is rare.Combination of acromeg...

Introduction: Radioactive iodine (131I) therapy is a safe and cost-effective choice in Graves’ disease (GD). Usually only one treatment with 131I is sufficient, however, individual characteristics of the disease can lead to its recurrence. The aim of this study is to determinate the risk factors that influence the recurrence of GD after 131I.Materials and methods: Retrospective cohort study in 528 patients with GD who did <sup...

Background: Subacute thyroiditis (SAT) is a transient thyrotoxic state characterized by suppressed TSH and low uptake of iodine 123 on thyroid scanning. SAT is a self limiting, possibly viral and inflammatory thyroid disorder that is usually associated with thyroid pain and systemic symptoms. Many factors can cause SAT. Infections are considered the most common cause. Vaccines can also lead to SAT.Case report: A 46-year-old male with a history of type 1 ...

PTTG1-binding factor (PBF) is an oestrogen-regulated proto-oncogene that is overexpressed in thyroid, breast and pituitary tumours. The precise role of PBF in tumourigenesis, however, has not been established, nor whether it is also an aetiological factor in non-endocrine cancer. In this study, we investigated PBF function in established colorectal cells and human tumours. Specific binding was evident between the tumour suppressor p53 and both endogenous and exogenous PBF in H...

Thyroid cancer is the most prevalent cancer among endocrine malignancies. Surgical resection combined with radioactive iodine therapy has been proved effective in treating differentiated thyroid cancer, including papillary and follicular thyroid cancers. However, regarding metastatic poorly differentiated or anaplastic thyroid cancers, there have been no available effective treatment modalities. The genomic instability, such as chromosome aneupolidy, represents a hallmark of s...

Objective: Acylation Simulating Protein (ASP) has been shown to regulate lipid clearance and glucose uptake in adipose tissue. In vitro studies demonstrate that insulin stimulates ASP secretion from adipocytes. Individuals with obesity and/or metabolic disturbances (insulin resistance and type 2 diabetes) have increased plasma ASP, suggesting ASP resistance. Therefore, the present study evaluates whether ASP levels are influenced by the metabolic profile of overweight and obes...
