The Roux-en-Y gastric bypass (RYGB) isuery ID="Q1" Text="Author:Kindly check the edit made in the article title." -->the most efficacious procedure of choice for obese patients with gastroesophageal reflux disease (GERD). The laparoscopic sleeve gastrectomy (LSG) has high rates of worsening GERD post operatively. Little evidence exists as to whether the use of objective foregut investigations has a meaningful impact on surgical procedure selection. This study examined whether a standard preoperative foregut evaluation protocol effected procedure selection in bariatric patients presenting for surgical evaluation with subjective symptoms of GERD. Patients presenting for bariatric surgery evaluation with subjective symptoms of GERD entered into a predetermined protocol of foregut evaluation. Patients initially underwent upper endoscopy and esophagram. If the patient desired a LSG, further testing with esophageal pH testing and high-resolution manometry was ordered. If significant pathology was discovered on any of these investigations RYGB was recommended, if investigations were normal LSG was felt to be permissible. Data were collected prospectively from July 2016 to December 2018 and reviewed. One hundred and thirty-three patients were identified as being eligible to have progressed through the protocol. Pathology was commonly discovered on preoperative evaluations. On EGD Barrett’s esophagus was discovered in 4%, grade C or D esophagitis in 18% and hiatal hernia in 36% of patients. On esophagram, hiatal hernia was discovered in 42.3% of patients. Abnormal esophageal motility was discovered in 41% and abnormal DeMeester scores in 83% of tested patients. Of the 133 patients evaluated, the final procedure the patient ultimately underwent was primarily determined based on protocol test results in 24.8% of cases. Foregut pathology is common in bariatric patients with subjective symptoms of GERD. Implementing a comprehensive protocol to objectively assess these patients leads to a significant clinical impact on which procedure these patients ultimately undergo.

Granulomatous mastitis is a chronic inflammatory breast disease with an enigmatic clinical presentation that can delay diagnosis and perpetuate ineffective treatments. We report our experience with the diagnosis and management of eighteen cases of granulomatous mastitis in the setting of an urban public hospital. The patients were identified after a retrospective review of pathology and surgery databases. Demographic, clinical, radiographic, histopathological data and treatment responses were reviewed. Out of a total of 18 patients, 8 patients were noted to be from Mexico. The mean age at presentation was 35 years and 11 of the 18 patients reported a pregnancy in the last four years. Most cases were unsuccessfully managed as bacterial breast infections initially; definitive treatment involved surgical excision and steroids. A complete symptomatic and radiographic resolution was documented in 8 of the 18 patients. Despite posing a challenge for the unsuspecting physician, an early diagnosis of granulomatous mastitis improves patient outcomes.

Obesity is public health problem of epidemic proportions. Esophageal dysmotility including achalasia is more commonly seen in an obese population. Standard therapy for achalasia can be complicated by hepatomegaly and a post-surgical anatomy in a pre- and post-bariatric population. Peroral endoscopic myotomy (POEM) has not been adequately studied in this population. A retrospective review of a prospectively collected database was completed. Patients who had undergone a Roux-en-y gastric bypass (RYGB) prior to or following a POEM were enrolled. Patient demographics, operative information and post-operative course data was collected. Six patients underwent POEM prior to or after RYGB. There were no peri-operative complications with an average length of stay of 1.2 days. Five patients experienced a clinical success with excellent symptom resolution. The one failure was in the setting of type III achalasia, but did have objective evidence of lower esophageal sphincter (LES) relaxation post-operatively. POEM in the setting of bariatric surgery is safe and feasible. The potential increase in GERD following POEM is obviated by RYGB anatomy. In an obese individual, a staged POEM prior to or following a RYGB is an appropriate treatment algorithm for obese and achalasia.

Malignant middle cerebral artery (MCA) infarctions are thought to be rare in children. In a recent hospital-based study, only 1.3 % of pediatric ischemic strokes were malignant MCA infarctions. However, population-based rates have not been published. We performed subgroup analysis of a population-based study to determine the rate of malignant MCA infarctions in children.In 2005 and 2010, all ischemic stroke-related emergency visits and hospital admissions among the 1.3 million residents of the five-county Greater Cincinnati/Northern Kentucky area were ascertained. Cases that occurred in patients 18 years and younger were reviewed in detail, and corresponding clinical and neuroimaging findings were recorded. Infarctions were considered malignant if they involved 50 % or more of the MCA territory and resulted in cerebral edema and mass effect.In 2005, eight pediatric ischemic strokes occurred in the study population, none of which were malignant infarctions. In 2010, there were also eight ischemic strokes. Of these, two malignant MCA infarctions were identified: (1) a 7-year-old boy who underwent hemicraniectomy and survived with moderate disability at 30 days and (2) a 17-year-old girl with significant prestroke disability who was not offered hemicraniectomy and died following withdrawal of care. Thus, among 16 children over 2 years, there were two malignant MCA infarctions (12.5 %, 95 % CI 0-29).Malignant MCA infarctions in children may not be as rare as previously thought. Given the significant survival and functional outcome benefit conferred by hemicraniectomy in adults, future studies focusing on its potential role in pediatric patients are warranted.

Introduction: In addition to the fluid intake in the form of intravenous maintenance or boluses in intensive care unit (ICU) patients, there are sources of fluids that may remain unrecognized but contribute significantly to the overall fluid balance. We hypothesized that fluids not ordered as boluses or maintenance infusions—“hidden obligatory fluids”—may contribute more than a liter to the fluid intake of a patient during any random 24 hours of critical care admission. Methods: Patients admitted to the Harlem Hospital ICU for at least 24 hours were included in this study (N = 98). Medical records and nursing charts were reviewed to determine the sources and volumes of various fluids for the study patients. Results: The mean hidden obligatory volume for an ICU patient was calculated to be 978 mL (standard deviation [SD]: 904, median: 645) and 1571 mL (SD: 1023, median: 1505), with enteral feeds compared to the discretionary volume of 2821 mL (SD: 2367, median: 2595); this obligatory fluid volume was affected by a patient’s need for pressor support and renal replacement therapy. Conclusion: Hidden obligatory fluids constitute a major source of the fluid intake among patients in a critical care unit. Up to 1.5 L should be taken into account during daily decision making to effectively regulate their volumes.

In human pancreatic cancers, promoter CpG island hypermethylation is observed in both benign and malignant tumors. It is thought that silencing of key growth-controlling genes by promoter hypermethylation may play a role in pancreatic oncogenesis. We have shown previously that sufficient levels of DNA methyltransferase (Dnmt) 1 expression are required for the development of murine intestinal tumors. Here, we report the results of a large-scale triple cross (progeny n = 761) between Apc(Min/+), Trp53(-/-) and Dnmt1 hypomorphic mice to investigate the role of Dnmt levels in the Apc(Min/+), Trp53(-/-) mouse models of acinar cell pancreatic cancer. Mutations of both APC and TP53 are observed in human pancreatic cancer. We found that tumor burden, but not tumor size, is significantly reduced with decreasing Dnmt1 levels, suggesting that DNA methylation is involved in pancreatic tumorigenesis in this mouse model. Detailed analyses showed that the reduction in tumor burden is the result of a decrease in both early- and late-stage lesions. We observed decreased levels of DNA methylation at candidate genes in the normal pancreas of Dnmt1 hypomorphic mice. Some of these genes showed increased methylation associated with tumorigenesis, suggesting that the tumor-suppressive effects of Dnmt1 hypomorphic alleles may be mediated in part through reduced promoter hypermethylation. Our work is the first in vivo study to show the effects of reduced Dnmt levels on pancreatic tumor development.
