EEC is a multisystemic disease secondary to a clonal histiocyte proliferation of non-Langerhans cells due to hyperactivation of the MAPK/ERK signaling pathway, with somatic BRAF V600E mutation present in 50% of cases with therapeutic implications. Between 50% of patients develop endocrinopathies, the most frequent being central diabetes insipidus (CDI). We present the case of a 42-year-old woman, diagnosed with CDI in 1998 without family history, treated with DDAVP [MRI: absen...

Introduction: Primary adrenal lymphoma is extremely rare. It accounts for <1% of extranodal lymphoma. It affects typically old males with bilateral adrenal gland involvement that leads to adrenal hypofunction. Prognosis is very poor due to the lack of optimum chemotherapeutic regimens.Case Report: A 71 yearr old man with prior history of non insulin dependent diabetes, was admitted to the emergency department with symptoms of progressive weakness, fa...

Introduction: Pseudohypoparathyroidism (PHP) is a heterogeneous group of endocrine disorders characterized by target-organ resistance to the action of PTH, manifesting with hypocalcemia, hyperphosphatemia, and increased serum concentrations of PTH. PTH receptor couples with the stimulatory G protein (Gsα), leading to cAMP formation. Most cases of PHP are caused by heterozygous inactivating mutations in the GNAS gene, encoding Gs〈 (PHP type 1A) or methylatio...

Introduction: Adrenocortical carcinoma (ACC) is a very rare neoplasm with an incidence of about one case per million population. It is an agressive tumor (overall 5-year survival 16–38%) and complete resection is the only curative treatment.Description of methods: We report four cases of ACC. The clinical and biochemical features at diagnosis along with clinical course of the disease are discussed.Results: Four patients (three...

Introduction: Megestrol acetate (MA) is commonly used to promote weight gain in patients with HIV infection. Adrenal insufficiency (AI) has been reported as an adverse effect of MA but this association is not frequently recognized in clinical practice and only few cases develop symptoms of AI. We describe a case of symptomatic AI precipitated by Graves’ hyperthyroidism in a HIV patient on long-term MA treatment.Case report: A 44-year-old man with HI...

Objectives: To evaluate the prevalence of hypertension in patients with type 2 diabetes mellitus (T2DM) and to analyze the clinical characteristics, the degree of achieved control and the associated antihypertensive treatment.Methods: Cross-sectional study which included patients with T2DM followed in a primary care setting. Data about age, sex, associated antihypertensive treatment, systolic blood pressure (SBP) and diastolic blood pressure (DBP) was co...

Objectives: To evaluate the prevalence of cardiovascular disease (CVD) and associated risk factors in patients with type 2 diabetes mellitus (T2DM) attended in a rural primary care setting.Methods: Cross-sectional study which included patients with T2DM followed in a rural primary care setting. Data about several cardiovascular risk factors was collected (age, sex, smoking, hypertension and dyslipidemia). Also, data about coronary heart disease (CHD) and...

Objectives: To evaluate the characteristics of patients with type 2 diabetes mellitus (T2DM) attended in a rural primary care setting and to analyze associated antidiabetic treatment and metabolic control.Methods: Cross-sectional study which included patients with T2DM followed in a rural primary care setting. Data about age, sex, body mass index (BMI), associated antidiabetic treatment, and HbA1c was collected.Results: Seventy nin...

Objectives: To evaluate the use of antidepressant drugs in patients with type 2 diabetes mellitus (T2DM) and to analyse if these drugs are associated with a more deteriorated metabolic control.Methods: Cross-sectional study which included patients with T2DM followed in a primary care setting. Data about age, sex, T2DM evolution, body mass index (BMI), HbA1c and associated antidepressant treatment was collected. Statistical analysis was performed with SPS...

The hypo and hyperthyroidism alter the synthesis/secretion of pituitary hormones, which in normal conditions present fluctuations in serum concentration during the 24h period. An intrinsic pituitary circadian clock might be related to these oscillations; however, the possible interaction between thyroid hormonal conditions and circadian clock gene expression in anterior pituitary is still unknown. The purpose of this study was to investigate the expression of core circadian cl...
