BACKGROUND: We have previously shown that men with coronary artery disease (CAD) have lower serum bioavailable testosterone levels than men with normal coronary arteries and this may have detrimental effects in coronary disease. It has been suggested that low androgen levels in men with CAD could be accounted for by the high prevalence of statin therapy and other factors such as smoking. We investigated the effects of statin therapy and smoking on testosterone in men with CAD....

BACKGROUND: Previous work has demonstrated a relationship between impaired carbohydrate metabolism and low serum levels of androgens in men. Men with diabetes have lower testosterone levels, and administration of physiological doses of testosterone improves glucose tolerance in these men. Men with coronary artery disease (CAD) have lower androgen levels than men with normal coronary arteries. We studied the relationship between testosterone, glucose, hypertension and DM in a p...

Background: Current evidence suggests that testosterone acts as a vasodilator in several vascular beds. This may have implications for men who are androgen deficient, in whom vascular reactivity may be impaired. We have studied vascular responses in vitro in femoral arteries from testicular feminised mice (Tfm), which lack a functional androgen receptor and are consequently androgen resistant and have reduced circulating levels of testosterone. Methods: Femoral arteries from m...

Introduction: The new guidelines for the management of hypothyroidism (HP) during pregnancy recommend a tighter treatment with levothyroxine (Lt4) to reach TSH values similar to those of pregnant women without thyroid dysfunction (TSH <2.5 mU/l in the 1st trimester-T- and TSH <3mu/l in the 2nd and 3rd T).Objectives: To assess the degree of control of HP in women followed during pregnancy according to the current criteria and the possible associat...

Introduction: Thanks to advances in genetics, idiopatic short stature have, more frequently, a molecular diagnosis. Mutations in the ACAN gene are responsible for different forms of syndromic short stature but were also described in association with idiopathic short stature or with joint damage and advanced bone age. Transmission is autosomal dominant. Less than 25 mutations have been described since 2010 and are localized all along the protein. The ACAN gene...

Background: Neutropenia due to anti-thyroid drug (ATD) therapy in Graves’ disease is rare but is well recognised. However, the effect of hyperthyroidism, prior to and after ATD therapy, on absolute neutrophil counts in patients with Graves’ disease is unclear.Methods: We noted neutrophil levels in consecutive patients with newly diagnosed Graves’ thyrotoxicosis in 2010–2013. We further noted neutrophil levels once patients had been tr...

Introduction: Involvement of different tissues and organs may be seen during the course of Graves’ disease (GD). We here aimed to present a case with GD and lung mass whose lung lesion disappeared after recieving antithyroid treatment.Case report: A 60 year old man admitted to our hospital with back pain. His thorax computed tomography (CT) revealed a 1.5×3 cm mass in lower right lobe. He was consultated by our clinic preoperatively before thor...

A 38-year-old woman with chronic autoimmune thyroiditis and hypothyroidism treated with levothyroxine (125 μg/day) was referred to our outpatient clinic with a history of sudden increase of goiter, weakness, dysphagia, dyspnea and suffocating sensation. Physical examination showed an enlarged, stony thyroid gland (three times of normal), without palpable cervical lymph nodes. Biochemical evaluation showed the following abnormalities: TSH 6.0 μU/ml (0.4–4.3), fre...

Introduction: Since primary amenorrhea because of ovarian dysfunction is a common complication in women with Turner syndrome (TS), sex hormone replacement therapy (HRT) is mandatory for induction of puberty, such as acquisition of secondary sexual characteristics and increased bone density. However, appropriate treatment protocols have not yet been established. To evaluate the efficacy of HRT on puberty induction in our department, a retrospective analysis was conducted.<p...

Genetic predisposition to autoimmunity is probably predominant. Major histocompatibility complex (MHC) alleles and non-MHC loci such as polymorphism of the cytotoxic T lymphocyte antigen-4 (CTLA4) gene have been identified as susceptibility markers. The autoimmune thyroid diseases are the most common organ-specific autoimmune diseases. They are characterized by the infiltration of the parenchyma by immune cells including T and B cells as well as macrophages. Ones a T cell is a...
