Introduction: Impaired insulin sensitivity accompanies polycystic ovary syndrome (PCOS). Women with PCOS are usually at risk of premature cardiovascular disease, which increases with age and body weight. We studied the link between insulin sensitivity measured by the Matsuda Insulin Sensitivity Index (MISI) adjusted to body mass index (BMI) and age in otherwise healthy PCOS women.Methods: 250 adult women with PCOS of reproductive age (18-43 years old) un...

Background: The clinical manifestations of thyrotoxicosis do not always correlate with the extent of thyroid biochemical abnormalities. Here, we report the case of a COVID-19 positive patient who presented with congestive heart failure as a first-time presentation of thyrotoxicosis. Case report: A 40-year-old female presented to Emergency Department with two days history of lower limb oedema and abdominal distension. She denied dyspnoea, chest pain, palp...

Objective: Adrenal venous sampling (AVP) is a reliable procedure to differentiate if in patients with primary aldosteronism (PA) aldosterone production is unilateral or bilateral and guide the treatment of these patients. Our objective was to describe their characteristics and the outcomes of the AVPs.Methods and patients: Observational longitudinal clinical study between July 2020 and September 2021 in patients who underwent AVP in our Hospital.<p c...

Objective: Flash glucose monitoring (FGM) allows non-invasive glucose level assessment. Our objective was to describe the characteristics of patients in a secondary referral hospital and their glycemic control expressed as FGM targets.Methods and patientsObservational longitudinal clinical study between January 2021 and December 2021 in patients with DM1 referred to a secondary care center in Montilla (Córdoba).Results: 101 patients included. Mean a...

Background: Pheochromocytoma and paraganglioma (PPGL) are rare endocrine tumours that secrete catecholamines. Methoxycatecholamines in free plasma or fractionated methoxycatecholamines in 24-hour urine collections are the recommended tests for the diagnosis of pheochromocytoma, based on which patients are referred for surgical removal of the adrenal gland. However, false-positive results from these tests remain a problem and some patients are referred for adrenalectomy due to ...

Objective: Adrenal venous sampling (AVS) is a reliable procedure to differentiate if in patients with primary aldosteronism (PA) aldosterone production is unilateral or bilateral and guide treatment of these patients. Our objective was to describe their characteristics and the outcomes of the AVS.Methods and patients: Observational longitudinal clinical study between July 2020 and November 2022 in patients who underwent AVS in our Hospital.<p class="...

Introduction: The gut hormone peptide YY 3-36 (PYY3-36) is secreted postprandially from intestinal L-cells to signal satiety. Peripheral administration of PYY3-36 suppresses food intake in rodents and humans. PYY3-36-based drugs are therefore promising anti-obesity treatments. It has been proposed that circulating PYY3-36 supresses appetite via the Y2 receptor (Y2R) in the hypothalamic arcuate nucleus (ARC). The vagus nerve, the majo...

Objectives: Broad insight into metabolic disturbances caused by diabetes ketoacidosis (DKA) and persist after pH normalization.Methods: Three groups of children with type 1 diabetes were recruited: after an episode of DKA (DKA, n=20), with established diabetes (EDM, n=10) and with new onset diabetes without DKA (NDM, n=10). EDM and NDM groups were matched to the DKA one for sex and age. Serum samples were collected at three tim...

Isolated hypogonadotropic hypogonadism (IHH) is known to decrease bone mineral density due to lack of pubertal surge of gonadotropins and deficiency of sex steroid hormone. Gonadal steroid hormones imbalance affects body composition. Nineteen Caucasian men, 22–48 year old (mean±S.D. 33±7.65) diagnosed with IHH (8 normosmic, 11 anosmic or hyposmic) were enrolled into the study. 14 patients were on hormone replacement therapy (HRT), 5 patients were ...

Introduction: Inferior petrosal sinus sampling (IPSS) is considered to be the gold standard for confirming the source of ACTH secretion in patients with Cushing’s syndrome (CS). Prolactin measurement during IPSS can improve diagnostic accuracy and reduces false negative responses.Patients and methods: 56 patients with ACTH-dependent CS were included (45 F/11 M, mean age 43.6±10.8 years and 90.1% Cushing’s disease) diagnosed since 2000. IPS...
