RESUMO
BACKGROUND: Hypnotherapy continues to be a controversial practice in medicine. It is surrounded by myth and misuses that instill doubts about its legitimacy and usefulness. PURPOSE: In this paper, we will distinguish pseudoscientific claims from evidence-based uses of hypnotherapy. RESULTS: The use and acceptability of hypnotherapy has varied over history. Pseudoscientific uses, based on outdated theories that it can access the unconscious mind, have delegitimized hypnotherapy. Modern theories that hypnosis uses common social, emotional, and cognitive processes combined with evidence-based methods have re-established the use of hypnotherapy in many physical and mental health disorders and symptoms. Currently it is a widely accepted and recommended treatment for irritable bowel syndrome, with evidence building for many other applications. CONCLUSION: Hypnotherapy, as a pseudoscience, can become unethical and cause distress for the patient and their families. Hypnotherapy, as an evidence-based treatment, can be used as a powerful tool to treat physical and psychological symptoms related to medical ailments.

Parathyroid hormone (PTH) is the primary regulator of blood calcium levels and bone metabolism. Insufficient levels of PTH lead to hypoparathyroidism, characterized by low serum calcium and elevated serum phosphate levels. It is most commonly caused by the inadvertent damage to the parathyroid glands during thyroid surgery. Patients with hypoparathyroidism are currently being treated with oral calcium and active vitamin D, and to avoid worsening hypercalciuria, target serum calcium levels are within the lower end of normal. With current treatment, patients may suffer from large swings in serum calcium and are at a substantial risk of chronic renal failure, nephrocalcinosis, and kidney stones. The recent FDA approval of recombinant human (rh) PTH(1-84) for the treatment of hypoparathyroidism adds PTH replacement therapy to the endocrinologist's armamentarium to treat this chronic disease.

CONTEXT: Bariatric surgery is increasingly popular but may lead to metabolic bone disease. OBJECTIVE: The objective was to determine the rate of bone loss in the 24 months after Roux-en-Y gastric bypass. DESIGN AND SETTING: This was a prospective cohort study conducted at an academic medical center. PARTICIPANTS: The participants were adults with severe obesity, including 30 adults undergoing gastric bypass and 20 nonsurgical controls. OUTCOMES: We measured bone mineral density (BMD) at the lumbar spine and proximal femur by quantitative computed tomography (QCT) and dual-energy x-ray absorptiometry at 0, 12, and 24 months. BMD and bone microarchitecture were also assessed by high-resolution peripheral QCT, and estimated bone strength was calculated using microfinite element analysis. RESULTS: Weight loss plateaued 6 months after gastric bypass but remained greater than controls at 24 months (-37 ± 3 vs -5 ± 3 kg [ mean ± SEM]; P < .001). At 24 months, BMD was 5-7% lower at the spine and 6-10% lower at the hip in subjects who underwent gastric bypass compared with nonsurgical controls, as assessed by QCT and dual-energy x-ray absorptiometry (P < .001 for all). Despite significant bone loss, average T-scores remained in the normal range 24 months after gastric bypass. Cortical and trabecular BMD and microarchitecture at the distal radius and tibia deteriorated in the gastric bypass group throughout the 24 months, such that estimated bone strength was 9% lower than controls. The decline in BMD persisted beyond the first year, with rates of bone loss exceeding controls throughout the second year at all skeletal sites. Mean serum calcium, 25(OH)-vitamin D, and PTH were maintained within the normal range in both groups. CONCLUSIONS: Substantial bone loss occurs throughout the 24 months after gastric bypass despite weight stability in the second year. Although the benefits of gastric bypass surgery are well established, the potential for adverse effects on skeletal integrity remains an important concern.
