Adamantinomatous craniopharyngiomas (ACPs) are among the most common intracranial tumours in children and they originate from undifferentiated pituitary progenitors. Mutations in the gene encoding for β-catenin (CTNNB1), which lead to the constitutive activation of the Wnt/β-catenin signalling pathway, have been associated with ACP. These tumours can invade adjacent structures, such as the hypothalamus, which makes comp...

Objectives: Previous studies have shown that metformin can reduce high-fat diet (HFD)-induced body weight gain and fat accumulation in the liver. However, the results obtained in animal models regarding the implication of metformin in the modulation of other whole-body and tissue-specific parameters, are controversial or need to be further explored. Consequently, we aimed to explore the capacity of metformin in modulating glucose/insulin metabolism, liver function, adiposity, ...

Obesity (OB) is caused by an energy imbalance that finally leads to adipose tissue dysfunction, and the appearance of multiple comorbidities, such as certain cancer types, including prostate cancer (PCa), which is one of the leading causes of cancer-related death in men population worldwide. In this context, periprostatic adipose tissue (PPAT) has recently gained increased attention as a key regulator of the pathophysiological relationship between OB and PCa. However, it has b...

Background and objective: According to recent studies, endocrine societies have modified the treatment criteria of subclinical gestational hypothyroidism, increasing TSH upper-limit value commonly set at 2.5 μU/ml to a new threshold set at 4 μU/ml. This change in criteria has responded to numerous studies which seem to indicate that the obstetrical complications do not generally increase despite this variation of the threshold TSH value. A further discussion lays now...

Introduction: The gold standard for evaluating Occult Parathyroid Adenomas (OPa) in patients with biochemical pattern of primary hyperparathyroidism (PHPT) is the 99mTc-MIBI parathyroid scan. 18F-Fluorocholine (18F-FCH) PET/CT has been proposed as a potential technique for detection and localization of OPa when 99mTc-MIBI scan is negative or inconclusive.Aims: To evaluate sensitivity and positive predictive value of 18F-Fluorocholine PET/CT in patients w...

Introduction: Treatment of hypothyroidism with levothyroxine is effective and simple; however, international guidelines advise starting with low doses in case of severe hypothyroidism, cardiac illness and aged population. Interestingly, and in contradiction to this dogma, high doses of levothyroxine have been given to patients with myxedema coma without untoward effects. The difference between myxedema coma, which deserves an intensive treatment, and longstanding severe hypoth...

Blackground: Parathyroid carcinoma is a malignant neoplasm affecting 0.5 to 5.0% of all patients suffering from primary hyperparathyroidism. This cancer continues to cause challenges for diagnosis and treatment because of its rarity, overlapping features with benign parathyroid disease.Case report: 50 years-old-woman, without relevant previous history. She begins to present asthenia, weakness of lower limbs, arthralgias, cramps and appearance of a painfu...

Background: Insulin Lispro 200 units/ml is a concentrated rapid-acting mealtime insulin (MTI) available as a prefilled, disposable pen (IL200) indicated for adults who require >20 units/day of prandial insulin. In comparison with Insulin Lispro 100 unit/ml prefilled pen, IL200 permits the delivery of an insulin dose in half the injection volume [1] and a lower glide force [2]. This study aims to understand physicians’ reasons to prescribe IL200, as well as characteriz...

Introduction: In the geographical area of southern Spain, in the province of Huelva, we have detected prevalent cases of Dunnigan’s partial hereditary lipodystrophy. The genealogy, the suspicion phenotype and the coordination with the Genetics Service and Reference center, have borne fruit, and more and more families are detected in Our Area. The lipodystrophies, in general, are rare diseases that affect the adipose tissue, disappearance of it in different parts of the bo...
