Case 1: Thirty-eight year woman consulted to gynecologist for oligomenorrhea in the last 4 years; PRL 51 μg/l and TSH 8.4 mU/l were discovered, initiating treatment with levotiroxine (f-T4). She got pregnant, persisting elevated levels of TSH and increasing f-T4, with normal campimetry. With the diagnostic of hyperthyroidism due to inadequate TSH secretion, treatment with PTU was initiated. After normal delivery, MRI showed a 22 mm. hypophisary macroadenoma and a transesp...

Insulin continuous s.c. infusion (ICSI) is an alternative therapy in selected diabetic patients when a good metabolic control is not achieved with multiple insulin doses (MID). We report the follow-up of patients with ICSI at least during 1 year in our centre.Patients and methods: Twenty-five patients (16 females, 9 males), with median age 38.4±12.5 years and diabetes evolution mean time 16.8±7.8 years, were changed from MID to ICSI due to defi...

Over the last decade 824 pituitary tumours have been removed in our centre. Of these, 114 (13.8%) were corticotroph adenomas. We present four unusual cases of corticotroph adenoma showing transition from Cushing’s disease to a hormonally inactive adenoma (case 1 and 2) or vice versa (case 3 and 4).Case 1: A 51-year-old man was admitted with a 2-year history of weight gain, arterial hypertension and chiasmatic syndrome. Cushing’s disease (CD) du...

Progression of metabolic syndrome to diabetes is not easily predicted in patients with morbid obesity. We hypothesized that no insulin-resistance is more usual as we thought.Objective: Evaluate prevalence of no insulin-resistance status in patients with morbid obesity.Patients and method: The study was undertaken in 130 patients with a BMI of 53.93±6.67 kg/m2. The morbidly obese patients were divided into four group...

Association between anorexia nerviosa (AN) and low bone mass has been demonstrated. Bone loss associated with AN involve hormonal and nutritional impairments, though their exact contribution is not clearly established. We compare bone mass in AN patients with women of similar weight with no criteria for anorexia nervosa, and a third group of healthy, normal-weight, age-matched women. The study included 48 patients with AN (DSM-IV criteria), 22 healthy eumenorrheic women with l...

Adiponectin and leptin have been described as potential contributors to bone metabolism. The effect of anticatabolic drugs on these adipokines and their relationship with bone metabolism have not been clearly clarified.Aims: (1) Evaluate adiponectin and leptin levels in osteoporosic postmenopausal women and their relationship with BMD, bone turnover and osteoclastogenesis markers. (2) Analyze changes on adiponectin and leptin levels after treatment with ...

Background: Primary hyperparathyroidism (PHP) is associated with increased rates of cardiovascular (CV) risk. Moreover, it is not fully clear whether surgery can attenuate CV risk. The intima-media thickness (IMT) of carotid vessels is considered a marker of atherosclerosis and CV events.Aim: Of the study was to evaluate IMT and some metabolic parameters in PHP patients.Subjects: Of 56 subjects were studied. Patients were divided i...

Low concentrations of vitamin D leads to secondary hiperparathyroidism, bone loss, and an increase of osteoporotic fractures in populations at risk. Adequate vitamin D and calcium intake is considered an essential component of postmenopausal osteoporosis management. Several epidemiological studies have assessed the prevalence of low serum vitamin D concentrations, indicating that vitamin D inadequacy (<30 ng/ml) is a problem world-wide.Aims: To evalu...

Estrogens play a protective role on the peripheral vascular endothelium in both females and males, however, no studies have reported on the effects of estrogens on male coronary arterial reactivity. We investigated the effects of estrogen therapy on coronary and endothelial function in a group of male to female transsexuals (M-to-F).Eight M-to-F transsexuals (group A), receiving oral estrogen therapy for 72 months were studied in comparison with 23 age-m...

The main aims of treatment of acromegaly are reversing symptoms and signs, removing the tumour, preventing disease recurrence, and improving survival. Increased mortality associated with acromegaly can be diminished if treatment is successful in reducing GH <2–2.5 ng/ml. We carried out a prospective study to assess whether recent advances in surgical technique (namely the endoscopic approach in a specialised centre encompassing specialist pituitary surgeons working in...
