We present a case of Inactivating PTH/PTHrP signalling disorder (IPPSD) revealed in aduthood in the context of respiratory alkalosis caused by covid-19 infection that led to worsening of the preexisting hypocalcemia and intensification of the usual hypocalcemic symptoms. A 39 year old female with history of subclinical hypothyroidism and bilateral cataracts was admited due to hypoxemia in the context of severe covid-19 infection with bilateral pulmonary infiltrates. She was vi...

Background: Basal tumor markers are valuable in preoperative evaluation of medullary thyroid carcinoma (Calcitonin and CEA), but are insensitive and nonspecific for papilary thyroid cancer (thyroglobulin). Even if their utility is questionable or not recomended in the evaluation of thyroid nodules, in some cases refered to endocrinology department they are available and can be misleading. We present two cases of thyroid nodules with very high preoperative tumor markers.<p ...

Background: Maturity onset diabetes of the young (MODY) has an estimated prevalence of 1–5% in the diabetic population, but misdiagnosis as type 1 or type 2 diabetes is common. It comprises a heterogeneous group of monogenic diseases characterized by primary dysfunction of β cell, young onset, autosomal dominant inheritance, without autoimmunity and without ketosis. Early diagnosis remains a challenge with important future implications, since it allows treatment opti...

Background: Parathyroid carcinoma is a rare cause of primary hyperparathyroidism. There’s an overlap between benign and malignant disease clinical presentation, but the presence of very high calcium levels (>14 mg/dl), markedly raised levels of PTH, palpable neck mass or severe bone/kidney disease is more common in parathyroid carcinoma. We present a case of primary hyperparathyroidism due to a parathyroid carcinoma, with unusual presentation.Ca...

The majority of adrenocortical tumors (ACT) are benign and hormonally non-functioning, in contrast to adrenocortical carcinomas (ACC), which are rare and usually very aggressive tumors. The differential diagnosis between these two entities is mainly based on unspecific and subjective criteria, contributing to the inaccuracy of diagnosis. Due to ACC molecular and biological heterogeneity, prognostic factors have a limited capacity to predict ACC clinical outcomes, leading to an...

Introduction: Pheochromocytoma is one of the major secondary causes of hypertension. The classic triad of pheochromocytoma symptoms of headache, sweating and tachycardia is not present in a high percentage of patients and is sometimes diagnosed as incidentaloma or atypical presentations.Case report: The authors present a 56-year-old man, with no known diseases, referred to Endocrinology evaluation by incidentaloma of the right adrenal gland, from the Pne...

Introduction: Secondary causes of diabetes refer to a category in which diabetes is associated with other diseases. They are thought to constitute less than 2% of the total cases of diabetes.Case report: A 56 year-old caucasian man, with no relevant medical history, presented to the Emergency Department with fatigue, polyuria, polydipsia, polyphagia and involuntary weight loss (6 kg in two weeks). He was hemodynamically stable and exhibited a glycaemia o...

Introduction: In chronic diseases a good psychological and behavioral adaptation is essential. Concerning diabetes the Insulin Delivery System (IDS) adopted tend to be an important factor of adaptation, global satisfaction and, above all, quality of life (QoL).Objectives: To analyze the QoL and IDS satisfaction and its relationship with psychopathological symptomatology in patients on continuous subcutaneous insulin infusion (CSII) therapy.<p class="...

Introduction: The endocrine system is often affected in the course of HIV infection. However, hypopituitarism and diabetes insipidus are uncommon disorders in these patients and have been related to drugs, infections of the central nervous system and neoplastic infiltration, in extremely rare cases.Case report: We present a case of a 42-year-old man with HIV infection known since 2005, but undergoing antiretroviral therapy only since 2010 (emtricitabine/...

Background: Continuous subcutaneous insulin infusion (CSII), alongside multiple daily injections (MDI) are the most frequent therapeutic of type 1 Diabetes Mellitus (DM). We aimed to evaluate the effects of the transition from MDI to CSII in the treatment of type 1 DM.Patients and methods: This retrospective longitudinal study analysed patients that received treatment with CSII from 2006 to 2014. Our sample had 85 patients, 35 male (41.2%) and 50 female ...
