Barrett's esophagus. Characterization and monitoring policy

The authors review the literature about the assessment of risks of adenocarcinoma occurring over the natural history of Barrett's oesophagus with an incidence much higher than in the general population. The best marker is histological analysis of the cylindric epithelium for signs of dysplasia or early carcinoma. Although there is much controversy about the practical benefit of regular surveillance, the authors recommend a yearly endoscopy with multiple site biopsies. With the new potent drugs aimed at controlling gastro-oesophageal reflux, regression of metaplasia might occur, as the authors have observed in 3 patients treated by 60 mg omeprazole. However, prospective studies are needed to confirm this finding and its possible effect on reducing the risk of adenocarcinoma.     

Endoscopic implantation of a biopolymer in the lower esophageal sphincter for gastroesophageal reflux: a pilot study

BACKGROUND: GERD is the most frequent disorder of the esophagus. Endoscopic minimally invasive treatment is desirable. However, the results of injection techniques have been disappointing. METHODS: A pilot study was conducted in patients with GERD, who required continuous therapy with a proton pump inhibitor, in which ethylene-vinyl-alcohol was injected into the muscle of the gastric cardia. Primary endpoints were the safety of the procedure, the effect on lower esophageal sphincter pressure and the stability of the injected material. A secondary endpoint was the effect on heartburn score after discontinuation of treatment with a proton pump inhibitor. RESULTS: Ethylene-vinyl-alcohol injection into the cardia resulted in circular diffusion of the product in 10 of 15 cases, suggesting that implantation into the muscle is feasible. Lower esophageal sphincter pressure was increased in 13 of 15 cases at 1 month and was sustained at a median follow-up of 6 months (range 4-12 months). Mean plus minus SEM of lower esophageal sphincter pressures (15 patients) were 12.2 plus minus 0.9, 18.7 plus minus 1.5 (p = 0.001 at baseline), and 16.7 plus minus 1.3 mm Hg (p = 0.038 from baseline) at, respectively, baseline, 1 month follow-up, and final follow-up. There was also a sustained reduction in heartburn score (off proton pump inhibitor) (3.40 plus minus 0.13 vs. 1.53 plus minus 0.24 and 1.87 plus minus 0.26 at baseline vs. 1 month and final follow-up, respectively; p < 0.01). Nine of the 15 patients had more than 50% of the injected material in place at second follow-up (at 6 months for 8 patients; at 12 months for 1 patient). In only 2 patients was there loss of more than 75% of injected ethylene-vinyl-alcohol. Persistence of greater than 50% of the material was associated with achievement of a circular injection. Only 4 patients had to resume therapy with a proton pump inhibitor. Mild retrosternal discomfort was observed in 8 patients; this disappeared in all cases after a maximum of 3 days. CONCLUSIONS: Ethylene-vinyl-alcohol implantation in the muscle of the cardia is feasible and safe. It leads to a sustained increase in resting lower esophageal sphincter pressure. This is associated with a sustained improvement in heartburn score for patients who previously required continuous therapy with a proton pump inhibitor.     

Unruptured sinus of Valsalva aneurysm with right ventricular outflow obstruction

The recommended operative management of unruptured sinus of Valsalva aneurysm consists of closure of the mouth of the aneurysm with or without aortic valve surgery. We report a case of unruptured aneurysm producing right ventricular outflow tract obstruction. Closure of the mouth of the aneurysm failed to relieve the obstruction, which was subsequently achieved by excising the aneurysmal wall overlying the outflow tract.     

Early menarche and premature natural menopause in Indonesia

Background: An association has been suggested between early menarche and premature natural menopause. However, existing studies in developed countries show mixed findings.

Aim: This study examined whether early menarche (first menstrual period ≤11 years old) is a factor for premature natural menopause (final menstrual period <40 years old) in the context of a developing country.

Subjects and methods: Data came from the Indonesia Family Life Survey (IFLS) 2014, which consists of 1608 post-menopausal women.

Results: Results of hierarchical logistic regression show that women who experienced early menarche (first menstrual period ≤11 years old) were found to be at higher risk of premature natural menopause (β?=?0.94, p?<?0.01, CI?=?0.24–1.63). The results are robust against potential confounding factors including individual reproductive history, lifestyle and sociodemographic characteristics, as well as unobserved factors at the household and community levels.

Conclusion: The findings support early monitoring of women with early menarche, especially those who have no children, for preventive health interventions aimed at mitigating the risk of adverse health outcomes associated with premature natural menopause.
