IJCR: http://escipub.com/international-journal-of-case-reports/ 0001 Jarboui et al., IJCR, 2017 1:6 IJCR: http://escipub.com/international-journal-of-case-reports/ 0002 Introduction: Intestinal duplications are mostly diagnosed in children, and less than 30% of all cases are diagnosed in adults [1,2]. Duodenal duplications (DD) are extremely rare and comprise less than 5% of all intestinal dupl...
A 45-day-old male infant presented with signs of acute intestinal obstruction for two days. Abdominal examination revealed a mass in the right lower abdomen. Ultrasound showed a cystic mass measuring 4x3 cm, in the right lower quadrant at the level of lower pole of right kidney. The plain abdominal radiograph showed haziness in the middle and lower third with bowel loops pushed to upper third o...
Brush-border maltase-glucoamylase (MGA) activity serves as the final step of small intestinal digestion of linear regions of dietary starch to glucose. Brush-border sucrase-isomaltase (SI) activity is complementary, through digestion of branched starch linkages. Here we report the cloning and sequencing of human MGA gene and demonstrate its close evolutionary relationship to SI. The gene is app...
we report the case of a 54-year-old iranian man who presented with melena from three months prior to admission. esophagogastroduodenoscopy and colonoscopy were normal. double balloon enteroscopy showed a pedunculated tumor located in the jejunum. he underwent laparotomy and resection of a 9.5 cm tumor from the distal jejunum. histopathologic evaluation confirmed the diagnosis of an inflammatory...
Prenatal ultrasound showing a double bubble is considered to be pathognomonic of duodenal atresia. We recently encountered an infant with prenatal findings suggestive of duodenal atresia with a normal karyotype who actually had a jejunal duplication cyst on exploration. A finding of an antenatal double bubble should lead to a thorough evaluation of the gastrointestinal tract and appropriate pre...
Enteric duplications are rare, but can occur anywhere along the digestive tract. Most of the patients become symptomatic in early childhood and only a few cases of adult patients have been reported in literature. Here we report a unique case of an adenocarcinoma arising in a coincidentally found cystic duplication of the small bowel.
Gene families are considered as groups of homologous genes which they share very similar sequences and they may have identical functions. Members of gene families may be found in tandem repeats or interspersed through the genome. These sequences are copies of the ancestral genes which have underwent changes. The multiple copies of each gene in a family were constructed based on gene duplicati...
We report here an extremely rare and unusual case of accessory nose associated with unilateral complete congenital choanal atresia. Although other types of nasal congenital nasal anomalies are not rare, however, extreme rarity of nose duplication is worth reporting, as it is an extremely rare type of nasal congenital deformity.
the prevalence of various intestinal helminthiasis have been determined by the examination of 8109 inhabitants of 20 villages located in the mountainous and coastal regions of the bandar abbas and minab areas in southern iran. a portion of people infected with each parasite were treated with the appropriate drug i and the worms expelled were collected, identified and counted. the results indica...
background: acute obstruction of the colon continues to be a lethal disease with little improvement in the mortality rate over the past 50 years. so, this study was undertaken to define the causes of colon obstruction and their probable changes after years. â methods: from 1979 to 2004, all records of patients with definite diagnosis of intestinal obstruction at all hospitals affiliated to shi...
