Background: AIP mutations cause sporadic and familial pituitary adenomas, but establishing the pathogenic role of missense AIP variants with unknown significance is difficult. The AIP interaction partner AHR – a xenobiotic-activated transcription factor – regulates transcription of xenobiotic-metabolising enzymes, mediates xenobiotic toxicity, and has been implicated in tumorigenesis.Aim: To describe the effect of AIP...

Introduction: Cushing’s disease (CD) is a rare disorder caused by an ACTH-secreting pituitary adenoma. Transsphenoidal surgery (TSS) is the recommended first-line treatment. However, an equivocal or even normal preoperative MRI can preclude the surgical management and the outcome of these patients.Objectives: Evaluate the relationship between preoperative MRI and TSS efficacy in patients with CD.Methods: Retrospective cohort s...

Introduction: Continuous subcutaneous insulin infusion (CSII) and multiple daily injections (MDI) are forms of intensified insulin therapy and the most used regimens for type 1 diabetes (T1D). Owing to its continuous basal output, hypoglycaemic events tend to be rarer with CSII. Our goal was to evaluate the differences in nocturnal hypoglycemia between these two treatment strategies.Methods: Retrospective analysis of 61 patients who had performed continu...

Introduction: HIV infection and combined antiretroviral therapy (cART) have been associated with lipodistrophy and changes in body composition. However, there are few studies on body composition evolution of HIV-infected patients, under cART.Aims: To evaluate the evolution of body composition in HIV-1 infected patients under cART over 5 years.Methods: Retrospective, observational study in a cohort of HIV-infected patients on cART. ...

Introduction: Pituitary surgery is currently considered the preferred treatment for Cushing’s disease (CD) and achieves remission in 55–85% of patients. Cortisol falls quickly after surgery, so that early post-operative cortisol level has been used as predictor of remission. There’s no agreement about optimal timing for cortisol measurement, with wide variability between centres.Objective: To assess the value of early post-operative serum ...

Introduction: Cushing’s disease (CD) is characterised by pathologic hypercortisolism caused by an ACTH-secreting pituitary adenoma. The primary modality for definitive treatment is pituitary surgery. The rarity of CD has made it difficult to establish reliable predictive factors of outcomes.Aim: Assessment of clinical, hormonal, radiological, surgical and histological findings as predictors of remission and relapse of CD.Metho...

In the last years estrogens have emerged as important regulators in male reproductive function. Spermatogenesis depends on the tight control of germ cell apoptosis and several studies indicated estrogens as playing a role in this process. The stem cell factor (SCF), a membrane-bound cytokine, and its receptor (c-kit), and the Fas ligand (FasL)/Fas receptor (FasR) system are powerful mechanisms controlling germ cell proliferation and apoptosis through the direct membrane commun...

Introduction: Increasing incidence of thyroid cancer might be a consequence of an increase detection of subclinical disease. The aim of this study was to compare the clinical and pathologic characteristics of nonincidentally discovered (NID) thyroid cancer with incidentally discovered (ID) on postoperative pathology.Methods: A retrospective medical record review of 104 patients with thyroid cancer was performed. A group I of 69 patients with NID thyroid ...

Introduction: Increased plasma levels of interleukin-6 (IL-6) in response to acute hypoglycemia have been well documented. Counter-regulatory hormones are likely to play a role in this inflammatory response.Objective: To study the interaction between IL-6 and counter-regulatory hormones during hypoglycemic stress.Methods: We conducted an exploratory single center study involving 23 patients (mean age = 34.15 ± 8.87 years, ...

Introduction: Mauriac syndrome is characterized by delayed growth and development, obesity, hepatomegaly and elevated transaminases in type 1 diabetes mellitus (T1DM) patients who have poor glycaemic control. Usually recognized in adolescence, when growth failure and pubertal delay became notorious.Case report: A 19-year-old male was referred to the Endocrinology Department due to short stature. He was severely distressed about his stature and younger ap...
