The Trial Of Calcium And Vitamin D For The Prevention Of Colorectal Adenomas, John A. Baron, Elizabeth L. Barry, Leila A. Mott, Judy R. Rees

Dartmouth Scholarship

BACKGROUND Epidemiologic and preclinical data suggest that higher intake and serum levels of vitamin D and higher intake of calcium reduce the risk of colorectal neoplasia. To further study the chemopreventive potential of these nutrients, we conducted a randomized, double-blind, placebo-controlled trial of supplementation with vitamin D, calcium, or both for the prevention of colorectal adenomas. METHODS We recruited patients with recently diagnosed adenomas and no known colorectal polyps remaining after complete colonoscopy. We randomly assigned 2259 participants to receive daily vitamin D3 (1000 IU), calcium as carbonate (1200 mg), both, or neither in a partial 2Å~2 factorial design. Women …

Investigation Of Potential Early Histologic Markers Of Pediatric Inflammatory Bowel Disease, Julie A. Bass, Craig A. Friesen, Amanda D. Deacy, Nancy Neilan, Julia M. Bracken, Valentina Shakhnovich, Vivekanand Singh

Manuscripts, Articles, Book Chapters and Other Papers

© 2015 Bass et al. Background: Early manifestations of pediatric inflammatory bowel disease (IBD) can be relatively nonspecific. Initial mucosal biopsies may not be conclusive, delaying the diagnosis until subsequent biopsies demonstrate typical histologic features of IBD. We hypothesized that certain inflammatory cell types may be utilized as early histologic indicators of IBD in children. Methods: A retrospective analysis compared histologic findings from initially inconclusive or negative endoscopic studies in 22 patients who were subsequently diagnosed with IBD (after diagnostic endoscopy) to those of 20 comparison patients with functional abdominal pain matched for age, gender, and study type. A pediatric …

Multiple Intussusceptions Associated With Polycythemia In An Anabolic Steroid Abuser , A Case Report And Literature Review, Y. Cavanagh, Nihar Shah Md, A. B. Thomas, A. Gupta

Gastroenterology

Intussusceptions are generally associated with mechanical lead points or localized inflammation that function as foci for intestinal telescoping. We present the case of a patient whose abuse of anabolic steroids resulted in the development of multiple simultaneous intussusceptions. Our patient had no additional identifiable risk factors for intussusception. Consistent with previous reports, corticosteroid induced polycythemia and its consequent hyperviscosity led to intravascular sludging and mesenteric ischemia with associated bowel wall thickening. The localized intestinal induration then served as mechanical foci for intussusception. Due to the illicit nature of anabolic androgenic steroid (AAS) abuse, the physiologic effects of supraphysiologic doses are …

Zaidi, Zulfiqar Ahmed Bhutta, Imran Ahmed, Didar Alam, Syed Asad Ali, Muneera Rasheed, Sajid Bashir Soofi, Ali Turab, Aisha Khizar Yousafzai

Department of Pathology and Laboratory Medicine

Background: Most studies of the causes of diarrhoea in low-income and middle-income countries have looked at severe disease in people presenting for care, and there are few estimates of pathogen-specific diarrhoea burdens in the community.
Methods: We undertook a birth cohort study with not only intensive community surveillance for diarrhoea but also routine collection of non-diarrhoeal stools from eight sites in South America, Africa, and Asia. We enrolled children within 17 days of birth, and diarrhoeal episodes (defined as maternal report of three or more loose stools in 24 h, or one loose stool with visible blood) were identified through …

Proton Pump Inhibitors And Corticosteroids As Synergistic Risk Factors For Candida Esophagitis, Nihar Shah Md, Yana Cavanagh, Oleg Shulik, Pooja Patel, Vincent A. Debari, Walid Baddoura

Gastroenterology

Abstract:

Introduction: Inhaled & systemic steroids are one of the well-documented risks factors for Candida esophagitis. However, the role of gastric acid suppression remains controversial.

Methods:

We conducted a retrospective case-control study of 420 patients consisting of 84 cases of Candida esophagitis and 336 matched controls. Our cohort was gathered from subjects evaluated from 2001 to 2012. The diagnosis of Candida esophagitis was based on endoscopic and/or histological criteria.

Results:

On univariate analysis, proton pump inhibitors were associated with higher risk (OR = 2.14; 95 % CI: 1.30 to 3.54); steroid use also increased the risk (OR = 3.55; 95% …

Burn Injury Alters The Intestinal Microbiome And Increases Gut Permeability And Bacterial Translocation, Zachary M. Earley, Suhail Akhtar, Stefan J. Green, Ankur Naqib, Omair Khan '15, Abigail R. Cannon, Adam M. Hammer, Niya L. Morris, Xiaoling Li, Joshua M. Eberhardt, Richard L. Gamelli, Richard H. Kennedy, Mashkoor A. Choudhry

Student Publications & Research

Sepsis remains one of the leading causes of death in burn patients who survive the initial insult of injury. Disruption of the intestinal epithelial barrier has been shown after burn injury; this can lead to the translocation of bacteria or their products (e.g., endotoxin) from the intestinal lumen to the circulation, thereby increasing the risk for sepsis in immunocompromised individuals. Since the maintenance of the epithelial barrier is largely dependent on the intestinal microbiota, we examined the diversity of the intestinal microbiome of severely burned patients and a controlled mouse model of burn injury. We show that burn injury induces …

Development Of Hyperplastic Polyps Following Argon Plasma Coagulation Of Gastric Antral Vascular Ectasia, Nihar Shah Md, Yana Cavanagh, Dharmesh H. Kaswal, Sohail Shaikh

Gastroenterology

The etiology of gastric antral vascular ectasia (GAVE) syndrome or gastric hyperplastic polyps (HPs) is not fully understood. We report a case of gastric HP arising in a patient treated with argon plasma coagulation (APC) for GAVE syndrome. Despite unclear etiologic progression, this and previously reported cases suggest a temporal relationship between the treatment of GAVE and HP. A 68-year-old male with a history of coronary artery disease, congestive heart failure and diabetes type II who initially presented with symptomatic anemia 2 weeks after starting aspirin and clopidogrel therapy. Diagnostic esophagogastroduodenoscopy (EGD) demonstrated diffuse GAVE. He was treated with 5 …

Cecal Bascule After Colonoscopy - Case Report And Review Of Literature, Nihar Shah Md, Hiren Patel Md, Varun Patel Md, Robert Spira

Gastroenterology

Cecal bascule is a rare disease variant of a cecal volvulus. It consists of upward and anterior folding of the ascending colon, forming a flap valve, and occluding the bowel lumen resulting in proximal cecal dilatation. Herein, we present a case of a patient who developed persistent abdominal pain few hours after a colonoscopy. CT scan of the abdomen revealed an upward and anterior folding of the cecum. Subsequently the patient was taken to the operating room for a right hemi-colectomy. This case emphasizes the importance to consider cecal bascule as a differential diagnosis in patients with persistent abdominal pain …

Gastroenterology

There are many different biochemical processes responsible for the hepatocelluar carcinoma (HCC) development that can be targeted for the prevention or halt progression of the HCC. Non-selective betablockers (NSBB) affects a multitude of intracellular biochemical and signaling pathways involved in carcinogenesis. Aim: To determine if NSBB may be protective for HCC in patients with cirrhosis and portal hypertension. Methods: We retrospectively enrolled 200 patients from medical records diagnosed with cirrhosis and portal hypertension between January 2001 and December 2013. Eighteen patients were excluded (taking selective beta-blocker and/or unavailable medical records). The etiology of cirrhosis, use of NSBB, demographics and the …

An Unusual Initial Presentation Of Hepatocellular Carcinoma As A Sellar Mass, Nihar Shah Md, Yana Cavanagh, Hamid Shaaban, Beth Stein, Sohail N. Shaikh, Dharmesh H. Kaswala, Walid Baddoura

Gastroenterology

Sellar masses are frequently adenomatous pituitary tumors. Metastatic disease is unusual, often mimicking the presentations of adenomas. Hepatocellular carcinoma (HCC) is the most common primary hepatic malignancy but unusual to have a pituitary metastasis (PM). A 65-year-old man presented with headache, diplopia, ptosis, decreased vision in the right eye and unintentional weight loss of 32lbs. Preliminary out-patient work-up revealed a mass in the pituitary region. Cranial imaging showed 3.1 cm × 3.2 cm × 4.4 cm lesion. Abdominal imaging (computed tomography and magnetic resonance imaging) demonstrated a lobulated, nodular and heterogeneous right lobe of the liver. Trans-sphenoidal resection of the …
