Objective Vitamin D (VD) plays a role in immune response. Recent data shows that low levels of VD could worsen COVID-19 outcomes. This study aimed to establish an association between VD levels among COVID-19 patients with clinical outcomes and inflammatory markers.Methods Prospective multicentric cohort study. Consecutively recruitment. Patients were grouped according admission status and level of VD [sufficient >30 ng/ml (VDS), insufficient 20–...

Introduction: The association of fasting glucose (FG) in early pregnancy (EP) with adverse outcomes for the mother and her offspring is well known, although the best cut-offs for diagnosis of Gestational Diabetes (GD) are not consensual.Objetive: Evaluate the impact of FG in EP in the management of pregnant women and obstetric and fetal outcomes.Methods: Retrospective cohort of pregnant women with GD diagnosed before 24 weeks of ge...

Introduction: Due to the growing prevalence of obesity, more women are overweight in early pregnancy, leading to adverse neonatal and obstetric outcomes.Objective: To evaluate the influence of maternal prepregnancy body mass index (BMI) on blood glucose levels at diagnosis of gestational diabetes (GD), obstetric and neonatal outcomes.Methods: Retrospective observational study including women with GD and singleton pregnancy, with fo...

Introduction: The American Diabetes Association guideline states that the long-term use of metformin may be associated with biochemical vitamin B12 (B12) deficiency and periodic measurement should be considered, although isolated serum B12 measurement has low sensitivity and specificity. Homocysteine (Hcy) and methylmalonic acid (MMA) are more sensitive biomarkers, the latter being more specific.Objectives: To estimate B12 deficiency in type 2 diabetics ...

Introduction: Klinefelter syndrome (KS) is characterized by the presence of supernumerary X-chromosome and thus a 47,XXY karyotype. This syndrome remains underdiagnosed, with only about 25% of patients being identified, and only 10% during childhood.Methods: Retrospective analysis of 11 KS patients followed-up in the Endocrinology Department of Coimbra’s Hospital and Universitary Center. The registered data included education and occupation, time an...

Introduction: Langerhan Cells Histiocytosis (LCH) is a rare heterogeneous idiopathic clinical entity involving clonal proliferation of Langerhan cells that may infiltrate most commonly bone, skin, lymph nodes or lungs. It affects mainly children between 5 and 15 years. The most common endocrine manifestation is diabetes insipida.Clinical case: The authors describe a case of a 19-year-old female patient, admitted in the Transition Follow-up of the Endocri...

Introduction: Insulin autoimmune syndrome or Hirata disease is a rare cause of hypoglycemia without prior insulin exposure. Approximately 400 cases were reported, mostly in Japan. It’s associated with other autoimmune diseases or exposure to sulfhydryl-containing drugs.Case report: A 56-year-old Caucasian woman presented with a 20-month history of hypoglycemia ameliorated by sugar intake. She had a past history of autoimmune thyroiditis, asthma and ...

Introduction: Malignant pheocromocytomas are rare. Metastatic disease may be present at the time of diagnosis or may only be evident after. Prognosis is poor. Currently there is no effective cure.Case report: We describe the case of a 66-year-old woman with a history of pheocromocytoma submitted to left adrenalectomy in 1992. In the past 10 years, she complained of episodes of dorsal back pain associated with hypertensive peaks and tachycardia. In 4/2010...

Background: Nonfunctioning pituitary adenomas are commonly diagnosed as large tumors. Most are detected incidentally during imaging studies. The aim of this study was to evaluate clinical presentation, characteristics and outcome of nonfunctioning pituitary macroadenomas incidentally (NFPMI) discovered.Methods: Twenty-seven patients (mean age 58.9 years, 45–82; 18 males:9 females) with NFPMI were studied. They represent 13.1% of NFPM followed in our...

Introduction: About 20% of fine needle aspiration biopsy of thyroid (FNA) with result of follicular tumour (FT) is malignant. Several factors have been suggested as indicators of malignancy.Objectives: To determine predictive factors of malignancy in FNA with result of FT.Methods: We evaluated retrospectively 140 clinical files of patients with cytology (ultrasound-guided or palpation) of FT. Presence of relationship between malign...
