The real cause of intussusception is not fully understood and a variety of conditions have been associated with it (Meckel diverticulum, polyps, duplication cysts, parasites, Henoch-Schönlein purpura, cystic fibrosis, hemolytic-uremic syndrome and infectious gastroenteritis). Furthermore few European countries, following WHO recommendation to monitor baseline incidence of intussusception before implementation of immunization program for rotavirus, used intussusception rate as a baseline value to compare the same figures in the period before and after introduction of vaccination...

Mandibular patterning information initially resides in the epithelium during development. However, how transcriptional regulation of epithelial-derived signaling controls morphogenesis of the mandible remains elusive. Using Shh(Cre) to target the mandibular epithelium, we ablated transcription factor Islet1, resulting in a distally truncated mandible via unbalanced cell apoptosis and decreased cell proliferation in the distal mesenchyme. Loss of Islet1 caused a lack of cartilage at the distal tip, leading to the two growing mandibular elements to be fused surrounding the rostral process of Meckels cartilage...

Meckel's diverticulum is the most common congenital abnormality of the small intestine that results from incomplete closure of the vitelline (omphalo-mesenteric) duct. This true diverticulum, ~2 ft from the ileocecal valve commonly found on the anti-mesenteric border of the ileum, is benign and majority asymptomatic. Diagnosis challenges arise when it became inflamed or presented in following ways, for example, haemorrhage (caused by ectopic pepsin-and hydrochloric acid-secreting gastric mucosa), intestinal obstruction (secondary to intussusception or volvulus) or the presence of diverticulum in the hernia sac (Littre's hernia)...

This study aimed to investigate the effect of contact (C-SSG) and no-contact (NC-SSG) handball small-sided games (SSGs) on motion patterns and physiological responses of elite handball players. Twelve male handball players performed 10 C-SSG and 10 NC-SSG while being monitored through the heart rate (HR) and rate of perceived exertion (RPE) as physiological responses and time-motion activities profile using video-match analysis. Both game conditions resulted in similar HR responses (P > 0.05), but the NC-SSG led to a higher RPE scores...

A 32-year-old man underwent wireless capsule endoscopy (WCE) (OMOM Capsule Endoscopy, Jinshan Science & Technology Company, Chongqing, China) for detecting obscure gastrointestinal bleeding 7.5 years ago. The result of WCE did not reveal any hemorrhagic focus, diverticulum or other abnormal changes of the gastrointestinal tract until its battery exhausted. The man then moved out from the area and lost to follow up without a report of capsule excretion. For confirming the diagnosis of recurrent melena and iron-deficiency anemia, the patient came to our clinical center...

INTRODUCTION: Meckel's diverticulum is the most common anomaly of the gastrointestinal tract, occurring in 1-3% of the general population. The most common complication of Meckel's diverticulum is intestinal obstruction. In this report, we describe a rare cause of intestinal obstruction due to Meckel's; the phytobezoar. After thorough literature review, the authors found about ten individual reports of the same topic. In all these cases, diagnosis was established intra-operatively. CASE PRESENTATION: A forty-seven-year old male presented to the emergency department with a one-day history of abdominal pain associated with vomiting and constipation...

Gastrointestinal bleeding from non-Meckel's small bowel diverticulosis is uncommon. Depending on the diverticulum's location, a patient's presentation can suggest either an upper or lower gastrointestinal source. We present two cases of bleeding from non-Meckel's small bowel diverticula. One patient was managed successfully with endoscopic therapy, and the second required surgical resection after two failed attempts at achieving hemostasis endoscopically.

Background. Malignant neoplasms arising in Meckel's diverticulum, a vitelline duct remnant, are rare yet well-documented. Case Presentation. A 53-year-old previously healthy female presented with an enlarging midline abdominal wall mass. A computed tomography scan revealed a mass involving the linea alba, bilateral rectus abdominis, and subcutaneous fat. Extensive clinical workup failed to demonstrate other lesions, except local and paratracheal/hilar lymphadenopathy. Histopathologic examination of the resected tumor demonstrated a spectrum of serous neoplasia including serous cystadenoma, papillary serous carcinoma with numerous Psammoma bodies, and a poorly differentiated component...

INTRODUCTION: The omphalomesenteric duct (OMD) or the vitelline duct (VD) is the embryonic structure connecting the vitelline sac to the primitive gut. It undergoes obliteration at 5-9 weeks of gestation. Failure of this duct to close, which occurs in approximately 2% of the population, can lead to various types of VD residual diseases. A persistent OMD remnant is pathological, and it typically presents in the pediatric population. Meckel diverticulum is the most common anomaly that results from failure of resorption of the OMD...

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the GI tract, they have a wide spectrum of clinical manifestations, and a small proportion of them present as an acute abdomen due to obstruction, perforation, or hemoperitoneum. We present a case of a perforated GIST of the Meckel's diverticulum and review the current literature on perforated GISTs. We ran a search on Pubmed and Google Scholar with the following terms "perforated GIST," "perforated Meckel's diverticulum," "GIST with peritonitis," and "GIST in Meckel's diverticulum...

In paper-based devices, capillary fluid flow is based on length-scale selective functional control within a hierarchical porous system. The fluid flow can be tuned by altering the paper preparation process, which controls parameters such as the paper grammage. Interestingly, the fiber morphology and nanoporosity are often neglected. In this work, porous voids are incorporated into paper by the combination of dense or mesoporous ceramic silica coatings with hierarchically porous cotton linter paper. Varying the silica coating leads to significant changes in the fluid flow characteristics, up to the complete water exclusion without any further fiber surface hydrophobization, providing new approaches to control fluid flow...

Perforation of Meckel's diverticulum is a rare complication in neonatal period. A 3-dayold term male neonate was transferred to our emergency room due to bowel perforation. Surgical exploration was done and perforated Meckel's diverticulum was detected. Pathological report of the tissue showed inflamed diverticulum with heterotopic gastric mucosa. This is the first report of Meckel's diverticulum perforation in a neonate in our country.

INTRODUCTION: Cerebral microbleeds (CMB), also known as cerebral microhemorrhages, are small areas of susceptibility on brain magnetic resonance imaging (MRI), that are increasingly detected due to the higher availability of high-field MRI systems and dedicated pulse sequences. The prevalence of CMBs increases in cases with cognitive decline. The current investigation assessed the poorly investigated radiologic-histopathologic correlation of CMBs on MRI. METHODS: The local ethical committee approved the current investigation...

Gallstone ileus due to erosion of one or more gallstones into the gastrointestinal tract is an uncommon cause of small bowel obstruction. The site of impaction is usually distal ileum, and less commonly the jejunum, colon, duodenum, or stomach. We report a rare case of gallstone ileus with impaction at the proximal small bowel and at a Meckel's diverticulum (MD) in a 64-year-old woman managed with laparoscopic converted to open small bowel resections. Patient was discharged home in stable condition and remained asymptomatic at 6-mo follow up...
