Temozolomide, an alkylating agent used in malignant gliomas, has been recently used too in the treatment of aggressive pituitary tumors. To date, two cases of Nelson’s syndrome has successfully treated with 5 days of 28-day cycle, but the follow-up has been shorter than 12 months. We reported the third patient with Nelson’s syndrome treated with temozolomide, who after an initial goal response to three 300 mg 5 days of 28-day cycles shown a clinical and biochemical (...

Autoimmune polyendocrinopathy syndromes (APS) gather a wide range of diseases. The association of autoimmune thyroid disease (ATD) with other organ specific diseases is frequent. Atrophic body gastritis (ABP) is characterized by the loss of ClH and intrinsic factor (IF) production. Both ATD and ABP are known to be associated since 1960 but there are scarce publications describing its clinical features.We review patients with this association selected fro...

Introduction: Ghrelin is a potent orexigenic brain-gut peptide with lipogenic and diabetogenic effects, possibly mediated by GHS-R. Cannabinoids also have orexigenic and lipogenic effects. AMPK is a regulator of energy homeostasis and we have previously shown that ghrelin and cannabinoids stimulate hypothalamic AMPK activity while inhibiting it in liver and adipose tissue, suggesting that AMPK mediates both the central appetite-inducing and peripheral effects of ghrelin and ca...

Surgery followed by 131I ablative therapy (IAT) is the usual treatment for patients with differentiated thyroid carcinoma (DTC). Thyroglobulin levels obtained 9–12 months after IAT under TSH stimulation (Tg2) is a very reliable marker for the presence of thyroid tissue. The value of stimulated thyroglobulin previous to ablation (Tg1) is more controversial. The aim of this study was to examine the relationship between Tg1 and Tg2.Material ...

Pituitary stem cells have been characterized in the postnatal pituitary. We now know they are organized in a niche and co-express specific markers such as Sox2, Sox9 or Gfra2. Although many studies by our group and others have been dedicated to its characterization in situ it is under discussion their role in the maintenance and turnover of the pituitary in physiological conditions or physiological pituitary challenges. It’s not known if the stem cells are requir...

Introduction, material and methods: Differentiated thyroid cancer is a pretty common reason for consulting in our specialty. In general terms, the prognosis is good in the main histological type but there are many others that can worsen the prognosis. It can determine the kind of surgery from hemithyroidectomy (e.g. microcarcinoma) to no intervention because of its extension at the moment of diagnosis. We have collected the data of our patients with differentiated thyroid canc...

Background: The hypothalamus-pituitary-adrenal axis (HPA) controls the neuroendocrine response to psychological and physiological stress. The balance of the hormones synthesised and secreted by these organs is tightly regulated. However, there are intrinsic differences in the relative expression of these hormones depending on sex, which can influence the magnitude of the endocrine response to stressors or the response to pharmacological treatments. Herein, we ...

Aims: We aimed to evaluate the relationship between glycosylated hemoglobin (HbA1c), time-in-range (TIR), Glucose Management Index (GMI) and coefficient of variation (CV) in a cohort of adult patients with type 1 diabetes (T1DM) and flash glucose monitoring (FGM).Material and methods: Cross-sectional study of patients with T1DM who FGM from Córdoba, Spain. Demographic and analytical data were collected. Glucose metrics and engagement statistics (adj...

The most feared nerve injury when treating thyroid cancer is that of the recurrent laryngeal nerve. However, there are other nerve complications, underestimated and underpublished, such as the lesion of the mandibular branch of the facial nerve, which requires a multiprofessional approach to recover functionality and esthetics, both affected.Clinical Case: A 44 year old woman, under study for anemia, underwent a cervical ultrasound that showed in the lef...

Introduction: The most frequent causes of ACTH-dependent Cushing’s syndrome are of pituitary origin and, less frequently, due to ectopic secretion of bronchial carcinoid, small cell lung cancer, and neuroendocrine tumors; it is rarely caused by an ACTH-producing pheochromocytoma.Methodology: We present a case of a 44-year-old female with a history of poorly controlled type 2 diabetes, hypertension, and long-standing obesity with no genetic predispos...
