Objective: To report a rare case of papillary thyroid carcinoma (PTC) in a thyroglossal duct cyst (TGDC).Case report: A 34-year-old peruvian male came to our hospital with a complaint of a swelling cervical mass in the anterior central side of the neck, which was growing since 6 months earlier. The patient had no significant past medical, surgical history and was completely asymptomatic. He denied any family history of thyroid disease or history of head ...

The RET receptor tyrosine kinase is an established oncogenic driver in multiple cancers. Activating RET point mutations give rise to the cancer syndrome Multiple Endocrine Neoplasia type 2 (MEN2), characterized by medullary thyroid carcinoma and pheochromocytoma. Correlations of specific RET mutations with MEN2 disease phenotypes and severity have been well documented, however the molecular mechanisms that distinguish the functions, locations, and protein interactions of speci...

Although we know the gene alterations associated with KAL 2, at present we still do not know certain mutations of the fibroblast factor receptor 1 gene (FGFR gene) that even show complete penetrance of the syndrome. Kallman syndrome is a genetic disease of embryonic development characterized by the association of hypogonadotropic hypogonadism due to GnRH hormone deficiency because of agenesis or hypoplasia of the olfactory sulci. Three subtypes have been described; the classic...

Aim: Describing bariatric surgery (BS) interventions in our center in the last five years, complications and effectiviness in weight loss and resolution of comorbities.Methodology: Prospective descriptive study on a cohort of people who underwent BS surgery at Virgen Macarena University Hospital, a tertiary hospital of the Public Health System of Andalusia, between January 2018 and May 2023. Patients who underwent revision surgery with a first previous s...

Background: Fractures are frequent in patients with chronic renal failure (CRF) with secondary hyperparathyroidism (SHPT) undergoing hemodialysis. Cinacalcet (CT) is a drug used in the reduction of hypercalcemia in these patients that acts through the lintel calcium sensor in the parathyroid gland. Recently, it has been pointed out that CT can reduce fractures in these patients by unknown mechanisms (EVOLVE Trials 2015).Objectives: To evaluate the effect...

Diabetes is a chronic disease that is often accompanied by multiple comorbidities and health complications such as overweight/obesity. In the late years therapies improving glycemic control while reducing body weight have become a convenient choice to treat diabetes. One of those therapies are GLP 1 receptor agonists. Dulaglutide allows for a once weekly dosing which might improve compliance; moreover its new application device ease the injection. We show the results of HbA1c ...

Oxytocin (OT) treatment improves heart functional recovery in rat model of myocardial infarct. We investigated in the H9c2 cell line (cardiomyocytes model), mechanism of OT action in simulated ischemia - reperfusion (sI-R). H9c2 cells were suspended in warm ischemic buffer and placed inside an anoxic chamber for 2 h at 37 °C, then ‘reperfused’ under normal nutrients and oxygen conditions for 2 h. OT presence during ischemia increased cell viability by 9.7±2...

Short metacarpals and/or -tarsals are observed in pseudohypoparathyroidism (PHP) type Ia (PHP1A) or pseudo-PHP (PPHP) caused by inactivating GNAS mutations involving exons encoding the stimulatory G protein alpha-subunit (Gαs). Skeletal abnormalities indistinguishable from those caused by Gαs mutations were present in five members of an extended Belgian family, who showed no evidence for abnormal regulation of calcium and phosphate homeostasis. Direct nucleo...

Objective: The identification of hyperandrogenism represents the cornerstone for the assessment of polycystic ovary syndrome (PCOs). However, its definition has always been troubling, mostly because of the poor accuracy shown by routine androgens assays. As suggested by literature, the application of more precise steroid measurement methods (such as liquid chromatography tandem mass spectrometry, LC-MS/MS) could improve the diagnostic workup. The aim of our study is to evaluat...

Introduction: The diagnosis of hyperparathyroidism can be challenging especially when surgery is mandatory and imaging techniques can not find the adenoma. PEt colina is a non-invasive diagnostic test that creates images of the parathyroid glands and detects abnormal activity. It is increasingly used and especially useful when there are no pathological findings in parathyroid scintigraphy.Methods: This is a retrospective observational study with data fro...
