BackgroundSerum urate (SU) has been positively and independently associated with type 2 diabetes in observational studies, but causal roles remain unclear.1 Triglycerides and glucose (TyG) index can be a useful and easily performed indicator of insulin resistance for daily clinical practice.2 The aim of this study was to evaluate the association between SU and TyG index in 22-year-old participants of a birth cohort.<p class="abs...

Introduction: Type 1 diabetes (T1D) is the most frequent children’s endocrinopathy in Portugal. The duration of the disease and metabolic control may affect the final height of pediatric patients. Despite the metabolic advantages of technological advances, such as continuous subcutaneous insulin perfusion (CSII), the effect on growth is unclear.Aim: To assess the impact of T1D treatment, with multiple daily injections (MDI) or CSII, on growth.<p...

Introduction: There are several endocrine causes of hyponatremia. SIADH is perhaps the most challenging, as patients do not always respond to initial correction measures and pharmacological treatment options are scarce. Urea is a viable option, but not commonly used.Methods: Analysis of patients with SIADH-induced hyponatremia (<135mEq/l) treated with urea per os in the Portuguese Institute of Oncology of Porto between August 2021 and Octobe...

Introduction: Nonislet cell tumour hypoglycemia (NICTH) is a rare complication of malignancy. The most common cause is overproduction of IGF2, which activates insulin receptors, resulting in hypoinsulinemic hypoglycemia. When a solitary fibrous tumor is responsible, it is called Doege-Potter syndrome.Case 1: 58-year-old woman, with a history of gastrointestinal stromal tumor and pleural solitary fibrous tumor with pulmonary and lymph node metastases. She...

Introduction: Bilateral adrenal masses may appear in the context of metastatic disease, adrenal congenital hyperplasia, primary tumors or infections, among others. Primary adrenal lymphoma is rare, accounting for approximately 1% of cases of non-Hodgkin lymphoma. Clinical case: 47-year-old woman, with a history of erythema nodosum and left hemithyroidectomy in the context of benign nodular disease. She presented with persistent fever and tiredne...

Introduction: Hypopituitarism is a rare diagnosis that is mainly due to primary pituitary neoplasms and their treatment. There are rarer causes such as hemorrhage/ischemia, traumatic brain injury, infections and infiltrative lesions. Clinical case: We herein present an 18-year-old male patient diagnosed with acute promyelocytic leukemia at the age of 14, with no evidence of central nervous system invasion in several lumbar punctures during his follow-up....

Introduction: Adrenal masses are among the most frequent tumours in humans (ACT). A vast majority of these tumours are benign (ACAs). Only a small subset of adrenal masses are malignant adrenocortical carcinomas (ACCs). Tumour size, tumour weight, hormonal function and pathologic criteria are useful clinicopathological criteria that can result in accurate diagnosis of most ACCs and ACAs.Case report: 31-years-old woman, without relevant previous history. ...

Introduction: Renal function and glucose lowering therapy, particularly metformin, influence serum lactate concentration in patients with type 2 diabetes (T2D). However, seems to be an acute precipitating event that triggers hyperlactacidemia and metabolic acidosis. This study aims to assess prevalence of hyperlactacidemia in T2D patients who presented at emergency room (ER), calculate relative risk of hyperlactacidemia in diabetics under metformin, identify predictive factors...

We presented the case of a 21 years old patient, derived from Primary Care to evaluate low testosterone levels (total testosterone (TT) 0.44 ng/ml). His father had delayed pubety and his mother menarche was at 11 years. No other personal history of interest. He had adequate child development and vaccination. No parotiditis. He referred some morning erections. Weight 59 kg, size 171 cm and BMI 20.17 kg/m2. Testes volume (TV) of 4-5 cc, scanty pubic hair. Tanner stage...

Case history: This 33-year old Scottish female presented in February 2017 with a 3-month history of vomiting, erythematous vesicular pruritic rash and three stone weight loss. The rash started 1 day postpartum in January 2015 and migrated from dorsum of feet to both lower legs, upper thigh and torso. A negative biopsy for pemphigus led the team to suspect necrolytic migratory erythema (NME) in November 2016. Her past medical history includes gestational diabetes with her third...
