OBJECTIVE: The aim of the current study was to assess symptomatic outcome and need for surgical reintervention for patients identified with pathological esophageal acid exposure by routine postoperative 24-hour pH-monitoring. BACKGROUND: Although laparoscopic fundoplication is associated with excellent short- and midterm results, recurrent symptoms pose an important challenge. Postoperative pH-monitoring is considered the "gold standard" for diagnosing recurrent GERD and frequently used for routine postoperative follow up...

Cramp-fasciculation syndrome (CFS) is a rare muscle hyperexcitability syndrome that presents with muscle cramps, fasciculations, and stiffness, as well as pain, fatigue, anxiety, hyperreflexia, and paresthesias. Although familial cases have been reported, a genetic etiology has not yet been identified. We performed whole-exome sequencing followed by validation and cosegregation analyses on a father-son pair with CFS. Both subjects manifested other hypersensitivity-hyperexcitability symptoms, including asthma, gastroesophageal reflux, migraine, restless legs syndrome, tremor, cold hyperalgesia, and cardiac conduction defects...

The intimate interplay of chitosan (CS) and graphene oxide (GO) in aqueous acidic solution has been explored to design upon casting, nanostructured "brick-and-mortar" films (CS-GO-f) and by acidic-to-basic pH inversion, porous CO2-dried aerogel microspheres (CS-GO-m). Owing to the presence of oxygenated functional groups in GO, good-quality crack-free hybrid films were obtained. Mechanical properties were improved independently of the GO content and it was found that a 20wt% loading affords hybrid film characterized with a Young modulus three times superior to that reached with the same loading of layered clay...

Proton pump inhibitors (PPIs) are known as a class of pharmaceutical agents that target H(+)/K(+)-ATPase, which is located in gastric parietal cells. PPIs are widely used in the treatment of gastric acid-related diseases including peptic ulcer disease, erosive esophagitis and gastroesophageal reflux disease, and so on. These drugs present an excellent safety profile and have become one of the most commonly prescribed drugs in primary and specialty care. Except for gastric acid-related diseases, PPIs can also be used in the treatment of Helicobacter pylori infection, viral infections, respiratory system diseases, cancer and so on...

Laparoscopic sleeve gastrectomy (LSG) has reached wide popularity during the last 15 years, due to the limited morbidity and mortality rates, and the very good weight loss results and effects on comorbid conditions. However, there are concerns regarding the effects of LSG on gastroesophageal reflux disease (GERD). The interpretation of the current evidence is challenged by the fact that the LSG technique is not standardized, and most studies investigate the presence of GERD by assessing symptoms and the use of acid reducing medications only...

BACKGROUND: A gastrostomy placement is frequently performed in pediatric patients who require long-term enteral tube feeding. Unfortunately, postoperative complications such as leakage, feeding intolerance, and gastroesophageal reflux frequently occur. These complications may be due to postoperative gastric dysmotility. Our aim was to evaluate the effect of gastrostomy placement on gastric emptying in children. METHODS: A prospective study was performed including 50 children undergoing laparoscopic gastrostomy...

Gastroesophageal reflux disease (GERD) is a common condition around the world. The management of this disease is less than satisfying given complexity of patient presentation and suboptimal diagnostic testing when employed for those poorly responsive to acid suppressive therapy. In this mini review, we discuss some new strategies employed for patients with suspected GERD to better understand disease pathophysiology. We compare the strategies and outline a clinically relevant approach in this difficult group of patients...

BACKGROUND: The strongest risk factor for oesophageal adenocarcinoma is reflux disease, and the rising incidence of this coincides with the eradication of Helicobacter pylori, both of which might alter the oesophageal microbiota. We aimed to profile the microbiota at different stages of Barrett's carcinogenesis and investigate the Cytosponge as a minimally invasive tool for sampling the oesophageal microbiota. METHODS: In this case-control study, 16S rRNA gene amplicon sequencing was done on 210 oesophageal samples from 86 patients representing the Barrett's oesophagus progression sequence (normal squamous controls [n=20], non-dysplastic [n=24] and dysplastic Barrett's oesophagus [n=23], and oesophageal adenocarcinoma [n=19]), relevant negative controls, and replicates on the Illumina MiSeq platform...

Gastroesophageal reflux disease (GERD) is a common condition that has a substantial impact on quality of life in patients and is a leading risk factor for esophageal adenocarcinoma. Now therapy with proton pump inhibitors (PPIs) is a basic method in the treatment of patients with GERD; however, one third of the patients do not respond to the therapy used. The causes of refractory GERD are a fairly large group of heterogeneous factors contributing to the inefficacy of PPIs in adequate dosage. Among these factors, there is low compliance by patients to the prescribed treatment regimen; nocturnal acid breakthrough; СУР2С19 gene polymorphism; chiasm syndrome with functional diseases of the gastrointestinal tract; non-acidic refluxes in a patient; thoracic esophageal motility disorders; the increased number and duration of transient lower esophageal sphincter relaxation periods; hiatus hernia; and misdiagnosis...

Cattle tick (Rhipicephalus microplus) is an important constraint on livestock production, particularly in tropical and subtropical areas. Synthetic acaricides are the primary method of control this thick. Resistance of R. microplus to synthetic acaricides has given rise to the need of new scientific investigations on alternative ways to control it. The objective of this work was to conduct a chemical investigation of Crescentia cujete L. fruit pulp and to evaluate the acaricide effect on R. microplus larvae of extracts, fractions, and isolated substances from this species...

α-amino acids bearing aromatic side chains are important synthetic units in the synthesis of peptides and natural products. Although various β-C-H arylation methodologies for amino acid derivatives involving the assistance of directing groups have been extensively developed, syntheses that directly employ N-protected amino acids as starting materials remain rare. Herein, we report an N-acetylglycine-enabled Pd-catalysed carboxylate-directed β-C(sp(3))-H arylation of aliphatic acids. In this way, various non-natural amino acids can be directly prepared from phthaloylalanine in one step in good to excellent yields...

Phytosterol is a natural component of vegetable oil and includes ergosterol (ER) and β-sitosterol. In this study, three new ergosterol monoester derivatives were obtained from the reflux reaction with ergosterol, organic acids (furoic acid, salicylic acid, and 2-naphthoic acid), EDCI, and DMAP in dichloromethane. The chemical structures were defined by IR and NMR. On the basis of the results, 2-naphthoic acid ergosterol ester (NE) had the highest tumor inhibition rate and was selected to study anti-tumor activity and its mechanism at doses of 0...

OBJECTIVES: Ureterocele management is considered to be one of the famous debates in pediatric urology. Despite some considering transurethral ureterocele incision (TUI) as a temporary line of treatment, others have reported good results in terms of being a definitive treatment. The present study evaluated the feasibility of TUI as a definitive line of management. Moreover, it studied the impact of presentation on the outcomes. PATIENTS AND METHODS: The charts of patients who had ureteroceles from 1995 to 2015 were retrospectively reviewed...

In patients with gastroesophageal reflux disease (GERD) and erosive esophagitis, treatment with proton pump inhibitors (PPIs) is highly effective. However, in some patients, especially those with nonerosive reflux disease or atypical GERD symptoms, acid-suppressive therapy with PPIs is not as successful. Alginates are medications that work through an alternative mechanism by displacing the postprandial gastric acid pocket. This study performed a systematic review and meta-analysis to examine the benefit of alginate-containing compounds in the treatment of patients with symptoms of GERD...

BACKGROUND: Several reports have mainly examined whether acute-phase technetium-99m dimercaptosuccinic acid (DMSA) scintigraphy can detect vesicoureteral reflux (VUR) and recommend acute-phase DMSA scintigraphy for initial imaging in children with febrile urinary tract infections (fUTIs). Recently, it has been emphasized the importance of identifying patients who have risks of recurrent fUTIs (r-fUTIs). To clarify the effectiveness of DMSA scintigraphy for predicting r-fUTIs in infants, we investigated the relationship between the defects on DMSA scintigraphy and r- fUTIs...
