Objectives: The daily diabetes hospital (DDH) is a functional device that offers to diabetics a close and customized attention by specialized staff. The objective is to evaluate the welfare activity, the diagnose and educative program of the DDH in 2007.Methodology: The following parameters have been analyzed: attended users, origin, main reason for consultation, previous Hba1c and to the 3 months, number revisions, income avoided, derivation place, tele...

Introduction: Type 1 diabetes mellitus (DM1) is frequently associated with other autoimmune diseases. Among children and adolescents, thyroid disease is the most common autoimmune endocrinopathy. The possibility of occult thyroid disease should be considered at diagnosis and when a patient is assessed at the annual review.Objective: The aim of our study was to determine the prevalence of autoimmune thyroiditis among children and adolescents with type 1 d...

Introduction: Currently self-glycemic control by the patient is essential to achieve a right metabolic control of diabetes. Nowadays, there are different systems that have proved useful for this aim.Objectives: Valuing any possible differences between systems and the relation with glycemia identified in our laboratory.Material and methods: We took blood samples by vein-puncture to 41 patients, and simultaneously we measured capilla...

Background: Long term exposure of INS-1 beta cells to elevated glucose concentrations has been observed to impair insulin expression, a phenomenon termed as glucose toxicity. Despite its potential relevance in the progression of diabetes, the underlying mechanisms is not yet fully understood.Aim: Target analysis of single, or a sub-group of metabolites has until now been the method of choice in mammalian cells to investigate the pathological state in ter...

The ‘Multiple Endocrine Neoplasia’ predominantly affect the pituitary gland, parathyroids, thyroids, adrenal glands and pancreas. We present the case of a patient with three different functioning endocrine gland tumours, but who cannot be included in any of these groups.Case report: Sixty-five-years-old female with recurrent episodes of nephritic colic and hypertension for 2 years; non-specific gastrointestinal complaints, hirsutism, hyp...

Resistance to thyroid hormones (RHT) is a rare syndrome, with autosomic dominant transmission, due to mutations in thyroid hormones beta-receptor gene. Clinical presentation is variable for the same mutation. This hypothesis must be considered in presence of high levels of thyroid hormones and TSH not suppressed.The evaluation of a 15-year-old female patient, in 1990, harbouring a thyroid nodule, secondary amenorrhea and visual and auditory impairment sh...

Objective: The pathogenesis of pituitary tumours is still incompletely understood. Somatotropinomas occur both sporadically and in the context of familial syndromes, such as multiple endocrine neoplasia type 1 (MEN1), Carney complex (CNC) and isolated familial somatotropinoma (IFS). Recently, germline mutations were reported in AIP (aryl hydrocarbon receptor interacting protein) gene in Finish and Italian families and in Finish patients with apparently sporadic pituitar...

Treatment for osteoporosis in children/adolescents is extremely important not only to improve bone quality but also because, if left untreated, could lead to severe and precocious loss of bone mass. Studies in growth hormone (GH) deficient adults, in turn, have shown that treatment with GH produce bone mass gain and improve the occurrence of both bone formation and reabsorption.The authors present the following case report of a 16 year old Caucasian fema...

Cushing’s syndrome is a rare disorder in children and adolescents. The diagnosis can be a challenge for the clinician, as its principal feature – obesity – is extremely common. We present three cases diagnosed in the last 20 years. The first one was a boy aged 17 that presented in 1984 with central obesity, acne, moon face with plethora, abdominal striae, easy bruising and skin atrophy. The investigations performed consisted in cortisol and ACTH plasma measureme...

The melanocortin-2-receptor accessory protein (MRAP) is a type I integral transmembrane protein required for the functional expression of the melanocortin-2-receptor (MC2R).Here we have investigated the expression and biochemical properties of mouse MRAP. Initially, mouse MRAP and MC2R tissue expression were determined by RT-PCR, being only present in the adrenal gland and fat tissue. Then, by in situ hybridisation studies using a full-length MRAP...
