Thyrotropin-secreting pituitary tumors are <1% of pituitary adenomas. Clinical manifestations are similar to other forms of hyperthyroidism. Most of them are diagnosed as macroadenoma (microadenomas <10%).Case 1: A 48 years old woman with menopause presented 6 years ago, consulting in 2009 for weight loss and palpitations. She had elastic goiter and distal tremor. Blood test: TSH 8.66 μUI/ml (0.2–4.2), FT4 4.7 ng/dl (0.7&#150...

Objetive: Evaluate the efficacy of subcutaneous HCG with or without FSH in male infertility associated to hypogonadotropic hypogonadism (HH).Patients and methods: Descriptive study of patients with HH treated with HCG s.c. with or without FSH, for fertility objective (2004–2011). The Treatment was initiated with HCG 500 UI/72 h s.c., periodic monitoring of testosterone and semen analysis was realized, adjusting doses up to 2500 UI/72 h. If no answer...

Introduction: Thyroid autoimmunity is related to iodine supply. Iodine nutrition has improved in our country, but the prevalence of autoimmune thyroiditis in our children is unknown.Objectives: To determine the status of iodine nutrition in children and adolescents in our city. To calculate local prevalence of thyroid autoimmunity and autoimmune thyroiditis in pediatric ages.Design: Cross-sectional epidemiological study.<p clas...

Introduction: Diabetes mellitus is associated with an increased risk of osteoporotic fractures, which leads to an increased risk of disability and frailty.Aims: To assess the prevalence of frailty in type 2 diabetes and to analyze the relationship with bone mineral density (BMD) and Trabecular Bone Score (TBS), fracture risk and prevalent fractures.Methods: We carried out a cross-sectional study of 75 diabetic patients (65±7 y...

Objective: Diagnosis of diabetes after transplantation (NODAT) has been described in up to 25% of cases. NODAT is a metabolically complex disorder, similar to type 2 diabetes. Factors that influence the development of NODAT are: BMI, HCV and immunosuppression. Objective: to know the prevalence and incidence of diabetes mellitus (DM) in liver transplant patients of our hospital.Patients and methods: Retrospective descriptive study of liver transplant pati...

It is known that the synthesis and release of pituitary GH is controlled by complex neuroendocrine mechanisms that involve several neuropeptides, such as GHRH, SST, PACAP, TRH, GnRH, Ghrelin, among other regulators. Previous reports indicate that, during vertebrate evolution, the potency and efficacy of these secretagogues may vary and play differential effects upon GH regulation. In this work we aimed to study, in vitro, the capacity of these peptides to control the ...

Objective: Cardiovascular risk factors (CVRF) persist with notable prevalence in patients with Cushing’s disease (CD) after remission: obesity/overweight up to 40%, hypertension (HTA) up to 60%, type 2 diabetes (DM-2) up to 60% and dyslipidemia up to 30% of cases. Persistence of metabolic syndrome in patients with controlled CD seems to be related to the duration of the disease before remission. The aim of this study is to describe the prevalence of CVRF in patients with ...

Introduction: Somatostatin analogs (SS-analogs) are the treatment option when there is a persistent disease despite surgical intervention. They can be also recommended as a first line treatment if surgery is not appropriate (non-curative or contraindicated surgery).Objetive: To evaluate the effect of first-generation SS-analogs (lanreotide and octreotide) on tumour shrinkage and biochemical control in naive patients.Methods: We per...

Introduction: After menopause, an abrupt drop in estrogen levels happens, while ovary androgens secretion declines gradually with aging. This relative hyperandrogenism may lead to the development of hyperandrogenic symptoms. However, the development of marked hirsutism and/or symptoms/signs of virilization, make necessary a detailed study in order to rule out tumorous cause (from adrenal glands or ovaries).Case report: 58 years old woman with progressive...

Objective: The aim of this study is to assess the impact of continuous subcutaneous insulin infusion (CSII) via a pump for patients with type 1 diabetes mellitus (DM1) on blood glucose and metabolic control.Materials and methods: A descriptive study was performed in a cohort of patients with DM1, showing blood glucose measurements at one month, six months and one year after implantation of the CSII. In addition, we performed an intra-subject before-after...
