The objective of the study is to evaluate the effect of daily administration of recombinant parathyroid hormone (PTH1-34), 20 μg, on serum calcium concentrations (Cas), and the requirements of oral calcium and calcitriol in patients with hypoparathyroidism. It is a prospective, longitudinal study, analytical, with intervention, in patients treated with high doses of calcium (> 7 g/day), with symptoms of hypocalcemia and/or intolerant to treatment. Serum levels of phosphorus (Ps) and Cas, urinary calcium excretion, oral doses of calcitriol and calcium were compared before and after administration of teriparatide, for three months on average, in patients with post-surgical hypoparathyroidism. We studied 16 patients with oral elemental calcium requirements of 22.5 ± 16 g/day of calcitriol 0.79 ± 0.4 µg/day. Cas at baseline was 7.6 ± 1.2 and Ps 5.4 ± 0.76 mg/dl. After administration of teriparatide, Cas was 9.0 ± 0.69 mg/dl (p = 0.007) and Ps of 4.5 ± 0.87 mg/dl (p = 0.003). Doses of calcium and calcitriol showed a statistically significant reduction (p = 0.0001 and 0.001, respectively). We conclude that use of recombinant parathyroid hormone can normalize Cas and Ps, with reduction in oral calcium and calcitriol requirements.

Background: The development of obesity is complex and multifactorial, with genetic, biological, environmental and lifestyle of each individual etiology. The different changes in metabolism of women, amongst other factors, lead to disorganization in the distribution of lipids, which gathered in large quantities within the viscera, increases cardiovascular mortality and it is a major determinant factor of the metabolic syndrome., Objective: To homologate and to apply concepts of evidence-based clinical practice in diagnosis and treatment of obesity in women in reproductive age and climacterium., Method: The experts' consensus was done by specialized physicians properly endocrinologists, gynecologists, surgeons, psychologists, nutrition specialists, physical activity and public health, according to their expertise and clinical judgment. The recommendations were based in diagnostic criteria aside from the level of evidence of previously established treatment guidelines, controlled clinical trials and standardized guides for women in reproductive age and climacterium with obesity., Results: The establishment of a nutritional intervention amongst other aspects of lifestyle is the first-line in the treatment of obesity. Current pharmacological treatments offer modest results in efficiency and security in weight reduction so these must go along with real changes in lifestyle in order to obtain better results in the short and long term., Conclusion: The high prevalence of overweight and obesity in our country, especially in women in reproductive age, compels us to pose and work in prevention strategies as well as diverse therapeutic plans favoring safe weight loss and results in the long term.

Objectives: to describe the frequency of sleep apnea in patients with acromegaly;to identify the proportion of candidates for treatment with positive airway pressure;to report our experience with the positive pressure titration process in acromegaly patients., Methods: A cross-sectional study that included the acromegaly cohort at the Centro Medico Nacional "20 de Noviembre" in Mexico City (n=44). A standard polysomnography (PSG) was carried out for each patient. A second PSG was done for purposes of CPAP titration., Results: A total of 35 patients were studied (80% of the cohort, 20 [57%] women). Polysomnography results showed that 34 subjects (97%, 95%CI 91-100%) had apnea hypopnea indexes (AHI) ≥ 5. No patient had central apnea. We identified 19 subjects with AHI ≥5 and Epworth ≥10, for a frequency of obstructive sleep apnea syndrome of 54% (95%CI 36-71%). A total of 31 patients (88%; 95%CI 77-99%) were deemed to be candidates for positive pressure treatment, but only 8 of them accepted CPAP. They required pressures that ranged from 10 to 18 cmH(2)O., Conclusions: Our results confirm a high prevalence of sleep apnea in patients with acromegaly, and provide evidence that the majority of those patients are candidates for treatment with positive pressure. Contrary to what has been reported, we identified no patients with central apnea.
