Single Anastomosis Duodenal Switch versus Classic Duodenal Switch: Long-term Outcomes from a Prospective Comparative Cohort Study.

PURPOSE: The literature on long-term outcomes of duodenal switch (DS) compared to single anastomosis duodenal switch (SADI-S) procedures is lacking. We evaluated the long-term outcomes of SADI-S compared to those after the classic DS procedure. METHODS: This is a follow-up report from a single-institution prospective cohort study comparing long-term outcomes of SADI-S versus DS both as one- and two-stage procedures (ClinicalTrials.gov: NCT02792166). Data is depicted as count (percentage) or median (interquartile range). RESULTS: Forty-two patients underwent SADI-S, of whom 11 had it as a second-stage procedure (26%). Of 20 patients who underwent DS, twelve had it as a second-stage procedure (60%). Both groups were similar at baseline. Median follow-up times for one-stage SADI-S and DS were 57 (24) and 57 (9) months, respectively (p = 0.93). Similar BMI reductions were observed after one-stage SADI-S (16.5 kg/m2 [8.5]) and DS (18.9 kg/m2 [7.2]; p = 0.42). At median follow-up of 51 (21) and 60 (15) months after second-stage SADI-S and DS, respectively (p = 0.60), surgical procedures yielded reductions in BMI of 20.5 kg/m2 (14.0) and 24.0 kg/m2 (13.9), respectively (p = 0.52). Follow-up rates were similar for one-stage (≥ 88%; p = 0.29) and second-stage procedures (≥ 83%; p = 0.16). Similar diabetes and hypertension remissions were found (p = 0.77; P = 0.54, respectively). Despite fat-soluble vitamin deficiencies at baseline, after supplementation, they were either eliminated or less prevalent long-term after SADI-S. Daily bowel movements were also less frequent. CONCLUSIONS: Long-term weight and comorbidity outcomes after SADI-S are similar to those of DS both as one- and two-stage surgeries. SADI-S procedure may allow for similar beneficial outcomes with less burden from gastrointestinal symptoms and fat-soluble vitamin deficiencies.

Eating disorders through the periodontal lens.

People with eating disorders suffer from a mental disorder that negatively affects their physical and/or mental health. The three most frequent eating disorders are binge eating disorder, bulimia nervosa, and anorexia nervosa. Environmental and genetic factors are involved in the pathogenesis of eating disorders in vulnerable persons. Although treatment varies among different types of eating disorders, nutrition, medical care combined with psychotherapy and medications are standard of care. The aim of this review is to give an overview of the oral health impact of eating disorders with a special emphasis on the periodontium. Oral health professionals have a unique role to play in the early diagnosis of eating disorders because of the important impact that eating disorders have on the oral cavity. In vomiting-associated eating disorders, the risk of erosive tooth wear is mainly localized to the palatal surfaces of the incisors. Emerging evidence also indicates a high frequency of gingivitis and gingival recessions associated with compulsive toothbrushing. A holistic approach, including oral health and functional rehabilitation, should be promoted by physicians, psychiatrists, and dentists for people with eating disorders.

Ulipristal acetate versus placebo for fibroid treatment before surgery.

BACKGROUND: The efficacy and safety of oral ulipristal acetate for the treatment of symptomatic uterine fibroids before surgery are uncertain. METHODS: We randomly assigned women with symptomatic fibroids, excessive uterine bleeding (a score of >100 on the pictorial blood-loss assessment chart [PBAC, an objective assessment of blood loss, in which monthly scores range from 0 to >500, with higher numbers indicating more bleeding]) and anemia (hemoglobin level of ≤10.2 g per deciliter) to receive treatment for up to 13 weeks with oral ulipristal acetate at a dose of 5 mg per day (96 women) or 10 mg per day (98 women) or to receive placebo (48 women). All patients received iron supplementation. The coprimary efficacy end points were control of uterine bleeding (PBAC score of <75) and reduction of fibroid volume at week 13, after which patients could undergo surgery. RESULTS: At 13 weeks, uterine bleeding was controlled in 91% of the women receiving 5 mg of ulipristal acetate, 92% of those receiving 10 mg of ulipristal acetate, and 19% of those receiving placebo (P<0.001 for the comparison of each dose of ulipristal acetate with placebo). The rates of amenorrhea were 73%, 82%, and 6%, respectively, with amenorrhea occurring within 10 days in the majority of patients receiving ulipristal acetate. The median changes in total fibroid volume were -21%, -12%, and +3% (P=0.002 for the comparison of 5 mg of ulipristal acetate with placebo, and P=0.006 for the comparison of 10 mg of ulipristal acetate with placebo). Ulipristal acetate induced benign histologic endometrial changes that had resolved by 6 months after the end of therapy. Serious adverse events occurred in one patient during treatment with 10 mg of ulipristal acetate (uterine hemorrhage) and in one patient during receipt of placebo (fibroid protruding through the cervix). Headache and breast tenderness were the most common adverse events associated with ulipristal acetate but did not occur significantly more frequently than with placebo. CONCLUSIONS: Treatment with ulipristal acetate for 13 weeks effectively controlled excessive bleeding due to uterine fibroids and reduced the size of the fibroids.

Bone metastases of differentiated thyroid cancer: impact of early 131I-based detection on outcome.

Bone is the second most frequent target of distant metastases in patients with differentiated thyroid cancer, and such forms carry a very poor prognosis. The impact of (131)I therapy in this setting is controversial. We describe the diagnostic circumstances and outcome of patients with bone metastases recently managed in two institutions. Among 921 consecutive thyroid cancer patients who had total thyroidectomy and (131)I ablation between January 2000 and December 2004 and who were subsequently monitored, bone metastases had been diagnosed in 16 patients. In three cases, the bone metastases were non-functioning (negative (131)I uptake) . These patients were treated with surgery and radiotherapy but progressed rapidly. The other 13 patients had functioning (positive (131)I uptake) bone metastases. In five of them, thyroid cancer was revealed by signs of distant involvement (bone pain, n = 4; dyspnea, n = 1). The bone metastases progressed in these five patients, despite local therapy and multiple courses of (131)I. The bone metastases in the remaining eight patients were discovered on the post-surgery (131)I therapy scan. Complementary radiological studies were negative except in one patient in whom one of the metastases (a 5 mm lesion of the right humerus) was visible on magnetic resonance imaging (MRI). Six of these patients showed a good response to (131)I therapy, with (131)I uptake and Tg levels becoming undetectable or showing a sharp fall. One patient refused (131)I therapy; bone metastases became visible on MRI within 1 year and the Tg level rose tenfold. The disease progressed in one patient despite (131)I therapy. Post-surgical (131)I ablation can contribute to early detection of bone metastases at a time when the Tg level may be only moderately elevated, when other radiological studies are negative, and when the disease is potentially curable by (131)I therapy.

Should 'low-risk' thyroid cancer patients with residual thyroglobulin be re-treated with iodine 131?

OBJECTIVE: The American consensus statement on patients with low-risk thyroid cancer, published in 2003, suggests repeat (131)I therapy if the thyroglobulin value is elevated at first follow-up. We evaluated this strategy in our practice. METHODS: Among 407 patients with thyroid cancer who had total thyroidectomy and (131)I ablation between January 2000 and December 2003, 12 patients with stage I thyroid cancer (any tumour (T), any node (N), metastasis (M)0 if < 45 years or T1, N0, M0 if > 45 years), were re-treated on the basis of their thyroglobulin level at first follow-up. Mean patient age was 32.8 years. None of them had a T4 tumour. Thyroglobulin levels after thyroid hormone withdrawal 'off-T4' ranged between 4.5 and 251 ng/ml (median 8). One to four courses of 3.7 GBq (131)I were given. RESULTS: Three patients had a negative (131)I therapy scan and an uneventful course. Two patients had slight residual uptake only in the thyroid bed and negative ultrasound examination. Four patients had isolated (131)I uptake in the mediastinal region. No abnormalities were found on complementary mediastinal imaging. This finding was interpreted as benign (131)I thymic uptake. The last three patients also had mediastinal thymic uptake associated with a slight thyroid bed uptake. One patient had a gradual increase in the thyroglobulin level, and underwent resection of nonfunctioning neck lymph nodes. Thyroglobulin levels declined in all other patients. CONCLUSIONS: No distant lesions were found in a group of young 'low-risk' thyroid cancer patients given empirical (131)I therapy for residual thyroglobulin. When blind (131)I therapy shows no uptake, or uptake limited to the thymus, (131)I therapy should not be repeated. The authors also briefly discuss the hypothesis that enhanced thymus might be a source of benign thyroglobulin secretion.
