Malrotation occurs when there is a failure in the intestinal rotation leading to abnormal fixation to the abdominal wall and a mesentery with a short root. Volvulus is a life-threatening complication of malrotation. It can lead to irreversible intestinal necrosis and requires immediate attention. Early recognition of malrotation and surgical correction could prevent the onset of volvulus. We describe 3 cases of children with a malrotation. Case A involves a 2-year-old boy who suffered from repeated episodes of vomiting. Case B, a 1-month-old female, was taken to the general practitioner after acute onset of crying and flexing of the legs. Case C, a 5-year-old-boy with no medical history, had started vomiting hourly. In presenting these 3 cases, we highlight the dangers of untreated malrotation and make recommendations on how to manage a patient suspected of having this congenital abnormality.

Intestinal malrotation occurs when there is a disruption in the normal embryological development of the bowel. The majority of patients present with clinical features in childhood, though rarely a first presentation can take place in adulthood. Recurrent bowel obstruction in patients with previous abdominal operation for midgut malrotation is mostly due to adhesions but very few reported cases have been due to recurrent volvulus. We present the case of a 22-year-old gentleman who had laparotomy in childhood for small bowel volvulus and then presented with acute bowel obstruction. Preoperative computerised tomography scan showed small bowel obstruction and features in keeping with midgut malrotation. Emergency laparotomy findings confirmed midgut malrotation with absent appendix, abnormal location of caecum, ascending colon and small bowel. In addition, there were small bowel volvulus and a segment of terminal ileal stricture. Limited right hemicolectomy was performed with excellent postoperative recovery. This case is presented to illustrate a rare occurrence and raise an awareness of the possibility of dreadful recurrent volvulus even several years following an initial Ladd’s procedure for midgut malrotation. Therefore, one will need to exercise a high index of suspicion and this becomes very crucial in order to ensure prompt surgical intervention and thereby preventing an attendant bowel ischaemia with its associated high fatality.

Primary small intestinal volvulus is defined as torsion in the absence of congenital malrotation, band, or postoperative adhesions. Its occurrence as an early postoperative complication is rare. A 40-year-old woman presented with rectal prolapse, and laparoscopic rectopexy was uneventfully performed. She could not have food on the day after surgery. She started oral intake on postoperative day 3 but developed abdominal pain after the meal. Contrast-enhanced CT revealed torsion of the small intestinal mesentery. An emergent laparotomy showed small intestinal volvulus, without congenital malformation or intestinal adhesions. We diagnosed it as primary small intestinal volvulus. The strangulated intestine was resected, and reconstruction was performed. The patient recovered uneventfully after the second surgery. To the best of our knowledge, this is the first report of primary small intestinal volvulus occurring after rectopexy for rectal prolapse. Primary small intestinal volvulus could be a postoperative complication after laparoscopy. © 2018 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and John Wiley & Sons Australia, Ltd.

Intestinal malrotation is a developmental anomaly affecting the position and peritoneal attachments of the small and large intestines during fetal life. Most often the diagnosis is established in the first year of life on the basis of abdominal pain and bile-stained vomiting secondary to bowel obstruction. The antenatal diagnosis can be suggested by identification of the complications such as bowel dilatation, ascites or meconium peritonitis. We describe two cases of isolated antenatal gastric malposition without any other associated anomaly that were confirmed after birth to be due to intestinal malrotation. We suggest that such an antenatal finding should alert the paediatrician to close clinical follow-up and prompt the diagnosis and surgical treatment in case of abdominal pain and/or bilious vomiting.

Intestinal malrotation is a rare congenital anomaly. In adults is very difficult to recognize due to the lack of symptoms. Diagnosis is usually incidental during surgical procedures or at autopsy. To review the occurrence and recognition of uneventful intestinal malrotation discovered during regular cases of bariatric surgeries. Were retrospectively reviewed the medical registry of 20,000 cases undergoing bariatric surgery, from January 2002 to January 2016, looking for the occurrence of intestinal malrotation and consequences in the intraoperative technique and immediate evolution of the patients. Five cases (0,025%) of intestinal malrotation were found. All of them were males, aging 45, 49, 37,52 and 39 years; BMI 35, 42, 49, 47 and 52 kg/m2, all of them with a past medical history of morbid obesity. The patient with BMI 35 kg/m2 suffered from type 2 diabetes also. All procedures were completed by laparoscopic approach, with no conversions. In one patient was not possible to move the jejunum to the upper abdomen in order to establish the gastrojejunostomy and a sleeve gastrectomy was performed. In another patient was not possible to fully recognize the anatomy due to bowel adhesions and a single anastomosis gastric bypass was preferred. No leaks or bleeding were identified. There were no perioperative complications. All patients were discharged 72 h after the procedure and no immediate 30-day complications were reported. Patients with malrotation can successfully undergo laparoscopic bariatric surgery. May be necessary changes in the surgical original strategy regarding the malrotation. Surgeons must check full abdominal anatomical condition prior to start the division of the stomach. Má-rotação intestinal é rara anomalia congênita em adultos de difícil reconhecimento devido à falta de sintomas. O diagnóstico é feito geralmente incidentalmente durante procedimentos cirúrgicos ou durante autópsia. Verificar a ocorrência e reconhecimento não eventual da má-rotação intestinal durante operações bariátricas sequenciais. Retrospectivamente foram analisados os prontuários médicos de 20.000 casos de operações bariátricas de janeiro 2002 a janeiro de 2016, procurando por ocorrência de má-rotação intestinal, sua interferência na técnica operatória aplicada e a evolução imediata no pós-operatório. Foram encontrados cinco casos (0.025%) de má-rotação intestinal em homens com idades de 37, 39, 45, 49 e 52 anos e IMC de 35, 42, 49, 47 e 52 kg/m2. O paciente com IMC de 35 kg/m2 também sofria de diabete melito tipo 2. Todos os procedimentos foram realizados através de laparoscopia, sem conversões. Em um paciente não foi possível mover o jejuno para o abdome superior a fim de realizar gastrojejunostomia; foi, então, realizada gastrectomia vertical. Em outro paciente, não foi possível reconhecer totalmente a anatomia devido às aderências intestinais e foi decidido realizar bypass gástrico com anastomose única. Nenhum vazamento ou sangramento foi identificado. Não houve nenhuma complicação pós-operatória. Todos os pacientes foram liberados 72 h após o procedimento e nenhuma complicação foi notificada nos primeiros 30 dias. A cirurgia bariátrica laparoscópica pode ser realizada com sucesso em pacientes com má-rotação. Mudanças talvez sejam necessárias com relação à anomalia. Os cirurgiões devem verificar toda a condição anatômica abdominal antes de iniciar a secção gástrica.

Intestinal malrotation is a rare cause of bowel obstruction in adults and it could create a perplexing situation for surgeons not familiar with this pediatric pathology. Symptomatic patients present either acutely with bowel obstruction and intestinal ischemia with a midgut or cecal volvolus, or chronically with vague abdominal pain. Several modalities can be used to describe the intestinal abnormality such as barium X-ray, computer tomography scans, angiography and sometimes also the explorative laparotomy. The authors report on a case 62 years-old women presented to Emergency Center for plurime episodies of biliar emesis and diffuse abdominal pain in the last 5 days and treated for bowel obstruction secondary to a midgut volvolus in anomaly of fetal intestinal rotation.

Because malrotation most commonly presents in infants, treatment recommendations for older children (>1 year) have been based on data obtained from small case series. The purpose of this study was to use a large national database to determine the clinical significance of older children presenting with malrotation to develop treatment recommendations for this group. Records of children undergoing a Ladd's procedure were identified in the Kids' Inpatient Database, an administrative database that contains all pediatric discharges from 27 states during 2000. Patient characteristics, associated diagnoses, operations performed, and mortality were evaluated. Discharge weighting was used to obtain a national estimate of the number of children older than 1 year treated for malrotation. Two hundred nineteen older children (>1 and <18 years) undergoing a Ladd's procedure were identified in the database. One hundred sixty-four (75%) of these patients were admitted for treatment of malrotation, whereas most of the remaining 55 patients (25%) were admitted for another diagnosis and underwent a Ladd's procedure incidental to another abdominal operation. Seventy-five patients underwent a Ladd's procedure during an emergency admission. Thirty-one patients had volvulus or intestinal ischemia, 7 underwent intestinal resection, and 1 patient died. Based on case weightings, it was estimated that 362 older children underwent a Ladd's procedure for symptoms related to malrotation in 2000 in the United States (5.3 cases per million population). These findings provide support for performing a Ladd's procedure in older children with incidentally found malrotation to prevent the rare but potentially devastating complications of this anomaly.

Midgut volvulus accompanied by intestinal malrotation is classified as a surgical emergency disease of the newborn, which emerges with the bilious vomiting or melena. This report presents four patients of this disease in our hospital, evaluated by color Doppler ultrasonography before surgical operation. All four patients were presented by bilious vomiting at the onset. By color Doppler ultrasonography method, the whirlpool sign which is the view of intestine and superior mesenteric vein rotated around with the axis of superior mesenteric artery, were shown in all cases. This whirlpool sign led to the diagnosis of midgut volvulus accompanied by intestinal malrotation. Intestinal contrast imaging was tested in three patients for the purpose of confirming the diagnosis. Repair of the volvulus and a ladd operation was performed in all four patients, without the excision of intestine because of no intestinal ischemic change. The clinical courses of four cases were good, and all patients were discharged within 17 days. Early diagnosis and timely surgical operation are essential for decreasing the possibility of occurring intestinal ischemic changes and improving clinical outcome after surgical operation. We propose that color Doppler ultrasonography is the powerful tool for the diagnosis of this disease, especially for the newborn, for whom the available diagnostic tests are limited.

In a textbook published in 1882, His exhibits drawings devoted to intestine development. The last figure depicts a typical case of gut malrotation, but there is no comment about this in the text. It could be possible that this omission should be due to the fact that mechanisms of gut development were not totally elucidated at this time. Copyright © 2011 Elsevier Masson SAS.

To describe the outcome of neonates with prenatal intestinal volvulus. All neonates with prenatal intestinal volvulus managed in our institution between May 2004 and December 2010 were retrospectively studied. All neonates with prenatal or neonatal diagnosis of prenatal intestinal volvulus were included. We analyzed age at diagnosis, fetal ultrasound (US) scan and magnetic resonance imaging (MRI) findings, clinical signs at birth, surgical findings, management, and postoperative outcome. Ten neonates with prenatal intestinal volvulus were identified. Prenatal US scans or MRI demonstrated evidence of meconium peritonitis in one fetus and bowel dilatation in 2 others. The mean gestational age at birth was 36 weeks (range, 31-38 weeks) and the mean birth weight was 2811g (range, 2050-3700g). One premature neonate developed respiratory distress and required ventilatory support at birth. In 7 neonates, clinical examination showed distended abdomen and emesis, whereas plain abdominal radiographs showed intestinal obstruction. All neonates underwent surgery and all had normal intestinal rotation, except one with total intestinal volvulus secondary to malrotation. Other causes of volvulus were suspected in 4 neonates: mesenteric defect (n=1), intestinal atresia (n=2) and narrow mesentery (n=1). Detorsion of total volvulus, ileostomy, or intestinal resection with primary anastomosis was performed in 2, 5, and 3 neonates, respectively. One patient with total intestinal volvulus secondary to malrotation died, whereas all other neonates survived. In one patient, the postoperative course was complicated by intestinal dysmotility of the distal small bowel requiring a secondary jejunoileostomy. Stoma closure was subsequently performed at 1 year of age with good outcome. One patient developed angiocholitis treated successfully with antibiotics. Median time to initiate enteral feeds was 7 days (range, 4-16 days) and all patients were subsequently weaned from parenteral nutrition. Median duration of parenteral nutrition was 29 days (range, 6-667 days). None of the patients had cystic fibrosis. Unlike postnatal volvulus, most prenatal volvulus occurs without malrotation. Although prenatal volvulus is a life-threatening condition, our results suggest that good long-term outcome can be achieved in most cases. Copyright © 2012 Elsevier Masson SAS. All rights reserved.

We present a case of extensive gastric heterotopia involving the small intestine associated with congenital short bowel syndrome and malrotation. The infant showed a normal mesenteric artery, without signs of "apple peel" deformity. Gastric heterotopia extended from the duodenum to the mid-ileum involving the short bowel. Gastric mucosa heterotopia may involve any segment of the gastrointestinal tract. It can be associated with pancreatic heterotopia and Meckel diverticulum. However, our case showed involvement of two-thirds of the small intestine without pancreatic heterotopia. To our knowledge, this is the first report of gastric heterotopia with congenital short gut syndrome and malrotation.

Intestinal volvulus (IV) can occur at various sites of the gastrointestinal tract. In Europe, IV in children is most frequently due to malrotation but in Asia Ascaris infestation is a common cause. This report reviews the experience with IV in children in Tunisia; analyzes the aetiologies as well as the clinical presentations and the benefits of the Ladd's procedure in the treatment of the IV. The authors retrospectively reviewed the case records of all children with IV from January 2000 to December 2009 at the Tunis Children's Hospital. There were 22 boys and nine girls with an age range of one day to four years. Twenty-five (80%) patients presented during the neonatal period. The most common presentation was bilious vomiting and dehydration. The aetiology was identified in all patients: Anomalies in rotation (n=22), omphalo-mesenteric duct (n=3), internal hernia (n=3), cystic lymphangioma (n=2), caocal volvulus (n=1). The bowel resection rate for gangrene was 16%. All patients with malrotation had Ladd's procedure performed. Five patients (19%) developed wound infections. One patient presented with adhesive small bowel obstruction. There were no recurrences following Ladd's procedure for malrotation. Two neonates (6%) died from overwhelming infections. Intestinal volvulus in our environment differs in aetiology from other reports. The resection rates are not similar, however. Early diagnosis reduced the high morbidity and mortality in our study.

A 46-year-old Chinese woman with a history of cholecystectomy and appendicectomy presented to the emergency department with symptoms of intestinal obstruction. Physical examination revealed central abdominal tenderness but no clinical features of peritonism. Plain radiography of the abdomen revealed a grossly distended large bowel loop with the long axis extending from the right lower abdomen toward the epigastrium, and an intraluminal air-fluid level. These findings were suspicious for an acute caecal volvulus, which was confirmed on subsequent contrast-enhanced computed tomography (CT) of the abdomen and pelvis. CT demonstrated an abnormal positional relationship between the superior mesenteric vein and artery, indicative of an underlying intestinal malrotation. This case highlights the utility of preoperative imaging in establishing the diagnosis of an uncommon cause of bowel obstruction. It also shows the importance of recognising the characteristic imaging features early, so as to ensure appropriate and expedient management, thus reducing patient morbidity arising from complications.

In developed countries, intestinal volvulus in children is most frequently due to malrotation. To review the experience in Nigeria, a retrospective analysis of 28 patients managed over 25 years at the Ahmadu Bello University Teaching Hospital, Zaria, Nigeria, was undertaken. There were 22 boys and 6 girls with an age range of 4 days to 14 years (median 4 years). There were equal numbers over and less than 5 years of age. Vomiting (89%) and abdominal distension (79%) were the most prominent features. Thirteen children (46%) had fever, associated with bowel gangrene in 5, while 8 (29%) presented with severe dehydration and shock. A plain abdominal radiograph was the only investigation performed, but the features were not specific for volvulus. In 11 children (39%) the volvulus was idiopathic, in 9 (32%) due to adhesions or bands, in 5 (18%) to malrotation, and in 1 each a Meckel's diverticulum, internal herniation, and ventriculoperitoneal shunt. Twenty-three patients had a small-bowel, 4 sigmoid, and 1 caecal volvulus. The bowel resection rate for gangrene was 46% (small bowel 9, sigmoid 3, caecum 1). All patients with malrotation had Ladd's procedure performed. Wound infections occurred in 10 patients (36%), complete wound dehiscence in 1, and recurrence in 1 (idiopathic terminal ileal volvulus). The mortality was 21%, mostly from overwhelming infection (2 neonates, 11-year-old, 3 >/= 5 years). Intestinal volvulus in our environment differs in aetiology from other reports. The resection rates are similar, however. This condition carries high morbidity and mortality.

Intestinal malrotations with midgut volvulus are surgical emergencies that can lead to life-threatening intestinal necrosis. This study evaluates the feasibility and the outcomes of laparoscopic treatment of midgut volvulus compared with classic open Ladd's procedure in neonates. The medical records of all neonates with diagnosis of malrotation and volvulus, who underwent surgery between January 1993 and January 2014, were reviewed. We considered the group of neonates laparoscopically treated (Group A, n = 20) and we compared it with an equal number of neonates treated with the classical open Ladd's procedure (Group B, n = 20). The median age at surgery was 8.4 days and the mean weight was 3.340 kg. The suspicion of volvulus was documented by plain abdominal radiograph, upper gastrointestinal contrast study, and/or ultrasound scanning of the mesenteric vessels. All the patients were treated according to the Ladd's procedure. Conversion to an open procedure was necessary in 25% of the patients. The mean operative time was 80 minutes (28-190 minutes) in Group A and 61 minutes (40-130 minutes) in Group B (P = .04). The median time to full diet (P = .02) and hospital stay (P = .04) was better in Group A. Rehospitalization because of recurrence of occlusive symptoms occurred in 30% of patients in Group A (n = 6) and in 40% of patients in Group B (n = 8). Among these, all the 6 patients of Group A underwent redo surgery for additional division of Ladd's bands or debridement; instead in Group B, 4 of 8 patients underwent open redo surgery. Laparoscopic exploration is the procedure of choice in case of suspicion of intestinal malrotation and volvulus. Laparoscopic treatment is feasible and safe even in neonatal age without additional risks compared with classical open Ladd's procedure.

Fetal intestinal volvulus is a rare life-threatening condition usually manifesting after birth with most cases being associated with intestinal malrotation. It appears on prenatal sonography (US) as a twisting of the bowel loops around the mesenteric artery, leading to mechanical obstruction and ischemic necrosis of the bowel. We report a case of intrauterine intestinal volvulus with ileal atresia, suspected when US revealed a typical "whirlpool" sign at 37 weeks' gestation, with a segment of markedly distended bowel loops and small amount of fetal ascites.

Duodenal obstruction caused by ileocolic intussusception in the absence of intestinal malrotation is extremely rare. We present and discuss the imaging findings in an infant with an intussusception secondary to a duplication cyst in whom sonography also showed inversion of the orientation of the mesenteric vessels and a distended stomach. A contrast medium study revealed a proximal duodenal obstruction with a beak appearance suggestive of midgut volvulus. At surgery, an ileocolic intussusception causing duodenal obstruction without concomitant malrotation or volvulus was found. The combination of duodenal obstruction and abnormal relationship of the mesenteric vessels as a result of ileocolic intussusception has not previously been reported in the literature.

Unusual case of acute appendicitis with left upper quadrant abdominal pain.

Acute appendicitis is one of the most frequent causes of surgical abdominal pain presenting to the Emergency Department. The diagnosis is confirmed by a set of clinical signs, blood tests and imaging. The typical presentation consists of periumbilical pain radiating to the right lower quadrant with peritoneal reaction on palpation (Mac Burney). In this article, we report a case of acute appendicitis presenting with a left upper quadrant pain due to intestinal malrotation and we describe the radiologic findings on computed tomography. With an Alvarado score of 4 and a nonconclusive abdominal U/S, the diagnosis of acute appendicitis was a long shot. Persistence of pain and increasing inflammatory parameters in her blood exams pushed the medical team to further investigate and a CT scan revealed intestinal malrotation with acute appendicitis. An examining physician should not be mislead by the atypical presentation of acute appendicitis and should bear in mind the diagnosis to avoid serious complications.

An unexpected cause of small bowel obstruction in an adult patient: midgut volvulus

2014-01-01

The most important complication of intestinal malrotation is midgut volvulus because it may lead to intestinal ischaemia and necrosis. A 29-year-old male patient was admitted to the emergency department with abdominal pain. Ultrasonography (US), colour Doppler ultrasonography (CDUS), CT and barium studies were carried out. On US and CDUS, twisting of intestinal segments around the superior mesenteric artery (SMA) and superior mesenteric vein (SMV) and alteration of the SMA–SMV relationship were detected. CT demonstrated that the small intestine was making a rotation around the SMA and SMV, which amounted to more than 360°. The upper gastrointestinal barium series revealed a corkscrew appearance of the duodenum and proximal jejunum, which is a pathognomonic finding of midgut volvulus. Prior knowledge of characteristic imaging findings of midgut volvulus is essential in order to reach proper diagnosis and establish proper treatment before the development of intestinal ischaemia and necrosis.

Midgut volvulus following laparoscopic gastric banding--a rare and dangerous situation.

2007-06-01

Intestinal malrotation is usually encountered in infants. Its main complication is midgut volvulus, a situation that presents itself with bilious vomiting. This symptom allows for early surgical treatment. A delay in diagnosis and treatment may lead to catastrophic sequelae, such as extensive bowel necrosis and death. This situation is rare but well known in adults. Laparoscopic gastric banding is a popular option for treating morbid obesity. One of the consequences of this procedure may be impaired vomiting when there is an obstruction below the band. In this paper, we present a case in which a patient suffered from midgut volvulus 4 years after a laparoscopic gastric banding. Owing to impaired vomiting, the diagnosis was delayed, therefore, severely endangering the patient. This case prompted us to suggest that malrotation should be actively sought after before or during any bariatric procedure.

Intrauterine midgut volvulus without malrotation: Diagnosis from the ‘coffee bean sign’

Fetal midgut volvulus is quite rare, and most cases are associated with abnormalities of intestinal rotation or fixation. We report a case of midgut volvulus without malrotation, associated with a meconium pellet, during the gestation period. This 2.79 kg, 33-wk infant was born via a spontaneous vaginal delivery caused by preterm labor. Prenatal ultrasound showed dilated bowel loops with the appearance of a ‘coffee bean sign’. This patient had an unusual presentation with a distended abdomen showing skin discoloration. An emergency laparotomy revealed a midgut volvulus and a twisted small bowel, caused by complicated meconium ileus. Such nonspecific prenatal radiological signs and a low index of suspicion of a volvulus during gestation might delay appropriate surgical management and result in ischemic necrosis of the bowel. Preterm labor, specific prenatal sonographic findings (for example, the coffee bean sign) and bluish discoloration of the abdominal wall could suggest intrauterine midgut volvulus requiring prompt surgical intervention.

Total small-intestinal volvulus with malrotation (TSIVM) classically presents in the neonatal period; it occurs much less frequently in the adult and is often misdiagnosed. Prognosis is directly related to the degree and duration of intestinal ischemia. Our goal is to describe our experience with TSIVM in the adult, to identify any specific findings and to discuss its management. Eleven patients who had undergone surgery for TSIVM at three centers between 1992 and 2012 were included. Surgery was performed as an emergency for five patients and surgery was elective for six. Mean follow-up was 63 months (range: 12-270). Six patients had had previous abdominal surgery. In nine cases, the diagnosis of TSIVM was made preoperatively, mainly by CT scan in eight cases. Seven patients had associated congenital failure of retroperitoneal fixation of the right colon and all of these underwent a Ladd procedure. The mortality rate was zero. Of the five patients who underwent emergency surgery, three required intestinal resections, one of whom developed a short bowel syndrome. The six patients who underwent surgery electively had no surgical complications. TSIVM is a very unusual finding in adult patients. The diagnosis can be made by CT scan with IV and oral contrast, but it often comes to light only at the time of surgery, even though the patients have often had recurrent episodes of abdominal symptomatology that dated back to childhood. The Ladd procedure, consisting of division of Ladd's bands, widening of the mesentery, and incidental appendectomy, remains the standard surgical repair. Digestive surgeons who care for adults should be familiar with this procedure, and it should be performed, as often as possible, with the assistance of a pediatric surgeon. Copyright © 2016.

To explore the value of employing the small intestinal feeding tube in treating high position intestinal obstruction of newborn infant. Five newborn infants (3 males and 2 females; 1 premature infant and 4 fully-mature infants; 2 had membranous atresia of duodenum, 1 had annular pancreas, and 2 had proximal small intestine atresia; 1 infant had malrotation). The duodenal membrane-like atresia and the blind-end of small intestine were removed and intestinal anastomosis was performed, which was combined with intestinal malrotation removal. Before the intestinal anastomosis surgery, the anesthetist inserted via nose a 6Fr small intestinal ED tube, made by CREATE MEDIC CO LTD of Japan[ the State Food and Drug Administration-instrument (Im.) 2007-NO.2661620]. Twenty-four hours after surgery, abdominal X-ray plain film was taken and patients were fed with syrup; 48 hours later, formula milk was pumped or lactose-free milk amino acids were given by intravenous injection pump through the feeding tube. The amount of milk and fluids was gradually increased to normal amount according to the condition. In initial 3 days the intravenous nutrition was given and one week after operation, the infants were fed through mouth in addition to pumping milk through the tube and stopped infusion. Ten to 22 days after operation, the tube was removed and the infant patients were discharged. All the five infants showed that the feeding through the nutrition tube was accomplished and the time of venous nutrition was reduced and fistula operation was avoided. None of the infants on question was off the tube and no jaundice exacerbation was found and the liver function was also found normal. At the very beginning, the tube was occasionally blocked by milk vale in one infant and after 0.9% sodium chloride solution flushing patency restored. After that, the feeding tube was washed once with warm water after feeding. In one infant vomiting occurred due to enough oral milk. The photograph of upper gastrointestine did not show anastomomotic stricture or fistula, or intestinal obstruction. After pulling out the tube, the symptoms disappeared and then the patient was discharged. One child was found to have diarrhea with no lactose nutrition liquid and given compound lactic bacteria preparations for oral administration, the symptom disappeared. In the 5 cases, the shortest hospital stay was 10 days and the longest was 22 days, the average stay was 16 days. Three to 5 days after operation the weight restored to birth weight, the weight had increased, when discharged, to an average of 5.5 g (kg·d). The small intestinal feeding tube was very effective for the postoperative nutrition maintenance of high position intestinal obstruction in newborn infants.

Waugh’s Syndrome: Blessing in Disguise

PubMed Central

Mohanty, Subrat K

2014-01-01

Waugh’s syndrome is the association between intestinal malrotion and intussusceptions. We report a case of Waugh’s syndrome in a one year old child who presented to us with acute bowel obstruction and bleeding per rectum. Due to malrotation, there was easy prolapsing of ileocolic region into the nonfixed ascending colon and the intussusceptum advanced into the descending colon and rectum without compromising vascularity of the bowel. In most of the cases the intussusceptum advancing into the rectum is associated with bowel gangrene even when ceacum is mobile. But in our case, mobile caecum with malrotation proved to be blessing in disguise in preventing such a complication. A Meckel’s diverticulum was also an incidental finding in this case. Waugh's syndrome is missed in cases of close reduction of intussusception and may be a reason for recurrence. Though a rare entity, the probability of Waugh’s syndrome should be kept in mind during surgery, during hydrostatic reduction of intussusceptions, and in case of recurrent ileocolic intussusceptions.

2008-06-01

Since its introduction in the early 1990s, the laparoscopic cholecystectomy has become the standard surgical intervention for cholelithiasis. The laparoscopic technique is being used in an increasing number of abdominal procedures. Intestinal volvulus is a rare complication of laparoscopic procedures, such as the laparoscopic cholecystectomy. A review of the literature revealed 12 reports of this complication occurring without a clear cause. Etiologic factors that have been postulated include congenital malrotation, previous surgery, and intraoperative factors, such as pneumoperitoneum, mobilization of the bowel, and patient position. In this paper, we review the literature for this rare complication and report on a case of cecal bascule (a type of cecal volvulus) occurring following the laparoscopic cholecystectomy. Of the 12 prior reports of intestinal volvulus following laparoscopic procedures, 8 of these followed the laparoscopic cholecystectomy, of which two were cecal volvulae. This is the first reported case of a cecal bascule occurring following the laparoscopic cholecystectomy.

Control of stomach smooth muscle development and intestinal rotation by transcription factor BARX1.

PubMed

Jayewickreme, Chenura D; Shivdasani, Ramesh A

2015-09-01

Diverse functions of the homeodomain transcription factor BARX1 include Wnt-dependent, non-cell autonomous specification of the stomach epithelium, tracheo-bronchial septation, and Wnt-independent expansion of the spleen primordium. Tight spatio-temporal regulation of Barx1 levels in the mesentery and stomach mesenchyme suggests additional roles. To determine these functions, we forced constitutive BARX1 expression in the Bapx1 expression domain, which includes the mesentery and intestinal mesenchyme, and also examined Barx1(-/)(-) embryos in further detail. Transgenic embryos invariably showed intestinal truncation and malrotation, in part reflecting abnormal left-right patterning. Ectopic BARX1 expression did not affect intestinal epithelium, but intestinal smooth muscle developed with features typical of the stomach wall. BARX1, which is normally restricted to the developing stomach, drives robust smooth muscle expansion in this organ by promoting proliferation of myogenic progenitors at the expense of other sub-epithelial cells. Undifferentiated embryonic stomach and intestinal mesenchyme showed modest differences in mRNA expression and BARX1 was sufficient to induce much of the stomach profile in intestinal cells. However, limited binding at cis-regulatory sites implies that BARX1 may act principally through other transcription factors. Genes expressed ectopically in BARX1(+) intestinal mesenchyme and reduced in Barx1(-/-) stomach mesenchyme include Isl1, Pitx1, Six2 and Pitx2, transcription factors known to control left-right patterning and influence smooth muscle development. The sum of evidence suggests that potent BARX1 functions in intestinal rotation and stomach myogenesis occur through this small group of intermediary transcription factors.

Objectives Malrotation of the femoral component can result in post-operative complications in total knee arthroplasty (TKA), including patellar maltracking. Therefore, we used computational simulation to investigate the influence of femoral malrotation on contact stresses on the polyethylene (PE) insert and on the patellar button as well as on the forces on the collateral ligaments. Materials and Methods Validated finite element (FE) models, for internal and external malrotations from 0° to 10° with regard to the neutral position, were developed to evaluate the effect of malrotation on the femoral component in TKA. Femoral malrotation in TKA on the knee joint was simulated in walking stance-phase gait and squat loading conditions. Results Contact stress on the medial side of the PE insert increased with internal femoral malrotation and decreased with external femoral malrotation in both stance-phase gait and squat loading conditions. There was an opposite trend in the lateral side of the PE insert case. Contact stress on the patellar button increased with internal femoral malrotation and decreased with external femoral malrotation in both stance-phase gait and squat loading conditions. In particular, contact stress on the patellar button increased by 98% with internal malrotation of 10° in the squat loading condition. The force on the medial collateral ligament (MCL) and the lateral collateral ligament (LCL) increased with internal and external femoral malrotations, respectively. Conclusions These findings provide support for orthopaedic surgeons to determine a more accurate femoral component alignment in order to reduce post-operative PE problems. Cite this article: K-T.

Complete intestinal volvulus is mainly related to congenital anomalies of the so-called intestinal malrotation, whereas segmental volvulus appears as a distinct entity, mostly observed during the perinatal period. Because these two situations are still lumped together, the aim of this study was to describe the particular condition of neonatal segmental volvulus. We analyzed the circumstances of diagnosis and management of 17 consecutives neonates operated for segmental volvulus more than a 10-year period in a single institution. During the same period, 19 cases of neonatal complete midgut volvulus were operated. Prenatal US exam anomalies were observed in 16/17 (94%) of segmental volvulus, significantly more frequently than in complete volvulus (p=0.003). Intestinal malposition was described peroperatively in all cases of complete volvulus, but also in 4/17 segmental volvulus (23%). Intestinal resection was performed in 88% of segmental volvulus when only one extensive intestinal necrosis was observed in complete volvulus. Parenteral nutrition was required in all patients with segmental volvulus with a median duration of 50days (range 5-251). Segmental volvulus occurs mainly prenatally and leads to fetal ultrasound anomalies. This situation, despite a limited length of intestinal loss, is associated to significant postnatal morbidity.

To report a rare case of a left paraduodenal hernia presenting as volvulus of the small intestine associated to an intestinal malrotation. A 2 months-old girl presented with history of bilious vomiting, sonography showed signs of volvulus and emergency laparotomy was performed and confirmed left paraduodenal hernia containing a part of the ileon, coecum with right colon and volvulus of the small intestine out of the hernia sac. Paraduodenal hernia is an uncommon cause of small bowel volvulus. It can be suspected by clinical and radiological findings, surgery is always required to prevent small bowel necrosis and to repair the defect.

Various reconstructions of the gastro-intestinal tract have been described in the past after distal gastrectomy. Among these, a Billroth II (BII) anastomosis can be performed with the addition of the Omega entero-enterostomy that may theoretically reduce the alkaline reflux. Given the significant complications associated with this procedure such as biliary reflux, marginal ulceration, and afferent loop syndrome, a revision into a Roux-en-Y anatomy is generally recommended. A 73-year-old healthy male was referred to our foregut surgery service for treatment of severe biliary gastritis. The patient previously underwent an open distal gastrectomy with a BII reconstruction followed by a Braun-type entero-enterostomy 6 months later. His main complaint was worsening daily biliary reflux with constant regurgitations, which were non-responsive to medical treatment. The preoperative endoscopy confirmed the diagnosis of severe biliary gastritis secondary to alkaline reflux. The distance between the gastro-jejunostomy and the Braun anastomosis was also measured with a pediatric colonoscope and the length of the efferent limb was estimated to be 80 cm. Identification of the afferent and efferent limb was complicated by the patient's incomplete intestinal malrotation with the angle of Treitz being present in the right hypochondrium. Intra-operative gastroscopy enabled visualization of the jejuno-jejunostomy and ensured correct interpretation of the anatomy. Subsequently, resection of the afferent limb completed the revision into a Roux-en-Y anatomy. The patient recovered well after the surgery and was discharged home on post-operative day 2. At 6 months follow-up, the patient's reflux symptoms have completely disappeared. BII reconstruction with or without Braun entero-enterostomy is a classic historical option following distal gastrectomy. Surgical revision of a BII into a Roux-en-Y anatomy is a good solution for severe biliary reflux and other long-term complications. Intra-operative endoscopy is a great adjunct to laparoscopic exploration in case of complex surgical procedures.

Cecal volvulus is uncommon in pediatric patients and there are few reports of cecal volvulus with cerebral palsy. Here, we report the case of a 19-year-old male patient who presented with abdominal distension, a history of cerebral palsy, refractory epilepsy due to lissencephaly, and chronic constipation. An abdominal x-ray and computed tomography without contrast enhancement showed fixed dilated bowel intensity in the right lower abdomen. Despite decompression with gastric and rectal tube insertion, symptoms did not improve. The patient underwent an exploratory laparotomy that revealed cecal volvulus. Cecal volvulus usually occurs following intestinal malrotation or previous surgery. In this patient, however, intestinal distension accompanying mental disability and chronic constipation resulted in the development of cecal volvulus. We suggest that cecal and proximal large bowel volvulus should be considered in patients presenting with progressive abdominal distension combined with a history of neuro-developmental delay and constipation.

Here we report the case of a pregnant 28-year-old who presented with acute upper abdominal pain. CT demonstrated midgut volvulus with short segment occlusion of the superior mesenteric artery (SMA). Emergent detorsion of the small bowel was performed, at which time underlying intestinal malrotation was discovered. Following detorsion, the SMA had a bounding pulse and did not require thrombectomy or revascularization. Fewer than 25 cases of midgut volvulus during pregnancy have been reported over the past 20years. To our knowledge, this is the first report of maternal midgut volvulus in which imaging captures the resultant occlusion of the SMA. Copyright © 2017 Elsevier Inc. All rights reserved.

The pathogenesis of febrile status epilepticus is poorly understood, but prior studies have suggested an association with temporal lobe abnormalities, including hippocampal malrotation. We used a quantitative morphometric method to assess the association between temporal lobe morphology and febrile status epilepticus. Brain MR imaging was performed in children presenting with febrile status epilepticus and control subjects as part of the Consequences of Prolonged Febrile Seizures in Childhood study. Medial temporal lobe morphologic parameters were measured manually, including the distance of the hippocampus from the midline, hippocampal height:width ratio, hippocampal angle, collateral sulcus angle, and width of the temporal horn. Temporal lobe morphologic parameters were correlated with the presence of visual hippocampal malrotation; the strongest association was with left temporal horn width (P < .001; adjusted OR, 10.59). Multiple morphologic parameters correlated with febrile status epilepticus, encompassing both the right and left sides. This association was statistically strongest in the right temporal lobe, whereas hippocampal malrotation was almost exclusively left-sided in this cohort. The association between temporal lobe measurements and febrile status epilepticus persisted when the analysis was restricted to cases with visually normal imaging findings without hippocampal malrotation or other visually apparent abnormalities. Several component morphologic features of hippocampal malrotation are independently associated with febrile status epilepticus, even when complete hippocampal malrotation is absent. Unexpectedly, this association predominantly involves the right temporal lobe. These findings suggest that a spectrum of bilateral temporal lobe anomalies are associated with febrile status epilepticus in children. Hippocampal malrotation may represent a visually apparent subset of this spectrum. © 2016 by American Journal of Neuroradiology.

The study aims to demonstrate the value of the 'tail sign' in the assessment of Dandy-Walker malformation. A total of 31 fetal magnetic resonance imaging (MRI), performed before 24 weeks of gestation after second-line ultrasound examination between May 2013 and September 2014, were examined retrospectively. All MRI examinations were performed using a 1.5 Tesla magnet without maternal sedation. Magnetic resonance imaging diagnosed 15/31 cases of Dandy-Walker malformation, 6/31 of vermian partial caudal agenesis, 2/31 of vermian hypoplasia, 4/31 of vermian malrotation, 2/31 of Walker-Warburg syndrome, 1/31 of Blake pouch cyst and 1/31 of rhombencephalosynapsis. All data were compared with fetopsy results, fetal MRI after the 30th week or postnatal MRI; the follow-up depended on the maternal decision to terminate or continue pregnancy. In our review study, we found the presence of the 'tail sign'; this sign was visible only in Dandy-Walker malformation and Walker-Warburg syndrome. The 'tail sign' could be helpful in the difficult differential diagnosis between Dandy-Walker, vermian malrotation, vermian hypoplasia and vermian partial agenesis. © 2015 John Wiley & Sons, Ltd.

In-utero intestinal volvulus is a rare but potential life threatening foetal complications. It is a surgical emergency and delay in diagnosis or treatment can increase the morbidity and mortality to the foetus. We report a case of mild foetal bowel dilatation diagnosed at 21 weeks of gestation. She was closely follow up and at 31 weeks of gestation, in-utero intestinal volvulus was diagnosed with the characteristic 'whirlpool' sign on ultrasound examination. This case emphasises the importance of early recognition and quick decision to delivery when intestinal volvulus is diagnosed. This enabled early surgical intervention to prevent further foetal morbidity.

Intrauterine intestinal volvulus is a difficult diagnosis to make, but has life-threatening implications for the fetus. We present a case of vulvulus without malrotation in a single fetus revealed in the 32nd gestation week in a 44-year-old woman. The presenting complaint of this patient was reduced fetal movements. Ultrasound examination showed a normal result except for a dilated stomach. Doppler ultrasound results were within the normal range. Computed cardiotocography (CTG) showed pathological results for acceleration and suspect values for variability. Short-term variability (STV) was at 2.80 ms. Due to the pathological computed CTG results a Caesarian section was carried out. The newborn received prompt postnatal surgical treatment and continues to be in good overall condition.

To present the method of Naegele forceps delivery clinically practiced by the lead author, its success rate, and morbidity and to evaluate the relationship between morbidity and the number of forceps traction applications. Naegele forceps delivery was performed when the fetal head reached station +2 cm, the forceps were applied in the maternal pelvic application, and traction was slowly and gently performed. In the past two years, Naegele forceps delivery was attempted by the lead author in 87 cases, which were retrospectively reviewed. The numbers of traction applications were one in 64.7% of cases, two in 24.7%, and three or more in 10.7%. The success rate was 100%. No severe morbidity was observed in mothers or neonates. Neonatal facial injury occurred most commonly in cases with fetal head malrotation, elevated numbers of traction applications, and maternal complications. Umbilical artery acidemia most commonly occurred in cases with nonreassuring fetal status. The significant crude odds ratio for three or more traction applications was 20 in cases with malrotation. Naegele forceps delivery has a high success rate, but multiple traction applications will sometimes be required, particularly in cases with malrotation. Malrotation and elevated numbers of traction applications may lead to neonatal head damage.

A male infant weighting 2970 g with total situs inversus, polysplenia, malrotation, duodenal stenosis, and complex cardiac anomalies, was admitted to our hospital. At 4 days of age, he underwent surgery that revealed a blood vessel passing over the duodenum from the mesenterium to the porta hepatis. A loose overbridging duodenoduodenostomy was performed to prevent compression of the vessel. The cardiac anomalies were corrected, and he could eat unrestricted diets. At the age of 1 year and 3 months, a 3-dimensional computed tomographic scan demonstrated that the vessel on the duodenum was the superior mesenteric vein (SMV), and it formed the portal vein with the splenic vein at the porta hepatis. Further, the scan revealed no compression of the SMV at the anastomosis. Doppler ultrasonography revealed a normal portal blood flow of 118.6 mL/min. This report describes the junction between the SMV and the splenic vein in a patient who had the SMV passing over the duodenum from the mesenterium. Correctly, patients previously diagnosed with a preduodenal portal vein could have a preduodenal SMV. The loose overbridging duodenoduodenostomy had advantages not only in passage of the anastomosis but also in maintenance of the portal blood flow for the congenital duodenal obstruction with the preduodenal SMV.

Primary intestinal lymphangiectasia is a disorder characterized by exudative enteropathy resulting from morphologic abnormalities of the intestinal lymphatics. Intestinal lymphangiectasia can be primary or secondary, so the diagnosis of primary intestinal lymphangiectasia must first exclude the possibility of secondary intestinal lymphangiectasia. A double-balloon enteroscopy and biopsy, as well as the pathology can be used to confirm the diagnosis of intestinal lymphangiectasia. A polymeric diet containing medium-chain triglycerides and total parenteral nutrition may be a useful therapy. A 17-year-old girl of Mongoloid ethnicity was admitted to our hospital with a history of diarrhea and edema. She was diagnosed with protein-losing enteropathy caused by intestinal lymphangiectasia. This was confirmed by a double-balloon enteroscopy and multi-dot biopsy. After treatment with total parenteral nutrition in hospital, which was followed by a low-fat and medium-chain triglyceride diet at home, she was totally relieved of her symptoms. Intestinal lymphangiectasia can be diagnosed with a double-balloon enteroscopy and multi-dot biopsy, as well as the pathology of small intestinal tissue showing edema of the submucosa and lymphangiectasia. Because intestinal lymphangiectasia can be primary or secondary, the diagnosis of primary intestinal lymphangiectasia must first exclude the possibility of secondary intestinal lymphangiectasia. A positive clinical response to the special diet therapy, namely a low-fat and medium-chain triglyceride diet, can further confirm the diagnosis of primary intestinal lymphangiectasia.

Delayed presentation of Duodenal Obstruction is a great diagnostic dilemma due to non-specific, varied & wide spectrum presentation. In this study, a 6 years female child presented with recurrent, intermittent, colicky abdominal pain with bilious vomiting, and occasional constipation from 9 months of her age, without having any significant family history or associated condition. She was initially diagnosed as a case of recurrent small bowel obstruction due to atypical variant of malrotation. But, after laparotomy, she was finally diagnosed as a case of recurrent duodenal obstruction due to Congenital Duodenal Web (Wind-Soak Variety) with a central hole in the fourth part of the duodenum. After uneventful recovery of post operative period the patient was discharged at 7th postoperative day & followed up upto 3 months. She had been found alright without any complication.

She was diagnosed with protein-losing enteropathy caused by intestinal lymphangiectasia. This was confirmed by a double-balloon enteroscopy and multi-dot biopsy. After treatment with total parenteral nutrition in hospital, which was followed by a low-fat and medium-chain triglyceride diet at home, she was totally relieved of her symptoms. Conclusion Intestinal lymphangiectasia can be diagnosed with a double-balloon enteroscopy and multi-dot biopsy, as well as the pathology of small intestinal tissue showing edema of the submucosa and lymphangiectasia. Because intestinal lymphangiectasia can be primary or secondary, the diagnosis of primary intestinal lymphangiectasia must first exclude the possibility of secondary intestinal lymphangiectasia. A positive clinical response to the special diet therapy, namely a low-fat and medium-chain triglyceride diet, can further confirm the diagnosis of primary intestinal lymphangiectasia. PMID:23316917

Traditionally, the placement of the tibial component in total knee arthroplasty (TKA) has focused on maximizing coverage of the tibial surface. However, the degree to which maximal coverage affects correct rotational placement of symmetric and asymmetric tibial components has not been well defined and might represent an implant design issue worthy of further inquiry. Using four commercially available tibial components (two symmetric, two asymmetric), we sought to determine (1) the overall amount of malrotation that would occur if components were placed for maximal tibial coverage; and (2) whether the asymmetric designs would result in less malrotation than the symmetric designs when placed for maximal coverage in a computer model using CT reconstructions. CT reconstructions of 30 tibial specimens were used to generate three-dimensional tibia reconstructions with attention to the tibial anatomic axis, the tibial tubercle, and the resected tibial surface. Using strict criteria, four commercially available tibial designs (two symmetric, two asymmetric) were placed on the resected tibial surface. The resulting component rotation was examined. Among all four designs, 70% of all tibial components placed in orientation maximizing fit to resection surface were internally malrotated (average 9°). The asymmetric designs had fewer cases of malrotation (28% and 52% for the two asymmetric designs, 100% and 96% for the two symmetric designs; p < 0.001) and less malrotation on average (2° and 5° for the asymmetric designs, 14° for both symmetric designs; p < 0.001). Maximizing tibial coverage resulted in implant malrotation in a large percentage of cases. Given similar amounts of tibial coverage, correct rotational positioning was more likely to occur with the asymmetric designs. Malrotation of components is an important cause of failure in TKA. Priority should be given to correct tibial rotational positioning. This study suggested that it is easier to balance rotation and coverage with asymmetric tibial baseplates; clinical research will need to determine whether the observed difference affects patellar tracking, loosening rates, or the likelihood of revisions after TKA.

Most foreign bodies that a child ingests pass harmlessly through the gastrointestinal tract. However, ingesting multiple magnets places a child at risk for serious viscus injury. A 16-y-old boy swallowed multiple magnets and presented with abdominal pain and emesis. Upon laparoscopy, the boy was found to have malrotation with volvulus caused by a cecal magnet attracted to a gastric magnet, resulting in a gastrocecal fistula. We review the management of magnet ingestion with an emphasis on a high index of suspicion and the use of laparoscopy for diagnosis, as well as the consequences of a coexisting rotational anomaly.

Volvulus without malposition--a single-center experience.

This is a single-center case series about the rare condition of volvulus without malposition and/or malrotation (VWM) in preterm babies. We focus on diagnostic difficulties, and our results should help to distinguish VWM as a distinct entity different from classical volvulus and segmental volvulus. Medical chart review of infants with VWM from 2003-2012 was used. A total of 15 patients were identified. All of them had volvulus in the absence of intestinal malposition or other associated intestinal pathologies. All patients were born prematurely. Emergency laparotomy was necessary in all 15 patients. Two groups were identified. Group 1 includes four patients with typical signs of meconium obstruction of prematurity (MOP). Small bowel resection was only necessary in one of these four patients, all survived without residual intestinal lesions. Group 2 consists of 11 patients without signs of MOP-small bowel resection and temporary enterostomy were necessary in all these children. Four patients presented with pneumatosis intestinalis on the abdominal plain film, suggesting necrotizing enterocolitis. Although two infants died, the survivors showed complete recovery. VWM is a distinct disease of prematurity. When associated with MOP, VWM has a favorable outcome of treatment. In contrast, VWM occurring in the absence of signs of meconium obstruction requires small bowel resection. VWM primarily affects the top of the midgut (ileum). Because of absent malposition, presentation of VWM may be uncharacteristic. Pneumatosis intestinalis in advanced VWM may lead to diagnostic difficulties and a delay in treatment.

Intestinal strictures were diagnosed in two captive cheetahs (Acinonyx jubatus jubatus). The cheetahs presented with lethargy, anorexia, diarrhea, and weight loss. The first cheetah had a stricture of the ileocecocolic junction diagnosed at necropsy. The second had an ileocecocolic stricture causing obstruction that was diagnosed at surgery. After resection and anastomosis, the cheetah recovered well. The etiology of the strictures remains undetermined. Intestinal stricture, particularly of the ileocecocolic junction, should be considered as a differential diagnosis for cheetahs with nonspecific gastrointestinal signs.

Intestinal Behçet disease (intestinal BD) and inflammatory bowel disease (IBD) share a lot of characteristics, including genetic background, clinical manifestations, and therapeutic strategies, especially the extraintestinal manifestations, such as oral ulcers, arthralgia, eye lesions, skin lesions, etc, but the coexistence of these 2 diseases are uncommon. Behçet disease with gastrointestinal involvement in ulcerative colitis (UC) patient has been reported in just 1 previous case report, but, which can not be diagnosed as definite intestinal BD based on Korean novel diagnositic criteria due to lacking the typical ileocecal ulcer. We present a 23-year-old woman with ulcerative disease who developed typical intestinal BD, which is the first case report of patient with coexisting UC and typical intestinal BD. This patient was diagnosed as coexistence of intestinal BD and UC base on the clinical manifestations, extra intestinal manifestations and typical colonoscopic findings. Steroid and methotrexate were administered. This patient achieved clinical remission and mucosal healing. Coexistence of intestinal BD and UC is uncommon, and the combination with steroid, methotrexate, and 5-aminosalicylic acids is an effective therapy.

Background Small bowel volvulus is a rare entity in Western adults. Greater insight into epidemiology and outcomes may be gained from a national database inquiry. Methods The Nationwide Inpatient Sample (1998–2010), a 20% stratified sample of United States hospitals, was retrospectively reviewed for small bowel volvulus cases (ICD-9 560.2 excluding gastric/colonic procedures) in patients ≥18-years old. Results There were 2,065,599 hospitalizations for bowel obstruction (ICD-9 560.x). Of those, there were 20,680 (1.00%) small bowel volvulus cases; 169 were attributable to intestinal malrotation. Most cases presented emergently (89.24%) and operative management was employed more frequently than non-operative (65.21% vs. 34.79%, P<0.0001). Predictors of mortality included age >50-years, Charlson comorbidity index ≥1, emergent admission, peritonitis, acute vascular insufficiency, coagulopathy, and non-operative management (P<0.0001). Conclusions As the first population-based epidemiological study of small bowel volvulus, our findings provide a robust representation of this rare cause of small bowel obstruction in American adults.

The purpose of this retrospective study was to compare the outcome for dogs with surgically treated large versus small intestinal volvulus between October 2009 and February 2014. A total of 15 dogs met the inclusion criteria and underwent an abdominal exploratory. Nine dogs were diagnosed with large intestinal volvulus during the study period, and all nine had surgical correction for large intestinal volvulus. All dogs were discharged from the hospital. Of the seven dogs available for phone follow-up (74 to 955 days postoperatively), all seven were alive and doing well. Six dogs were diagnosed with small intestinal volvulus during the study period. One of the six survived to hospital discharge. Three of the six were euthanized at the time of surgery due to an extensive amount of necrotic bowel. Of the three who were not, one died postoperatively the same day, one died 3 days later, and one dog survived for greater than 730 days. Results concluded that the outcome in dogs with surgically corrected large intestinal volvulus is excellent, compared with a poor outcome in dogs with small intestinal volvulus. The overall survival to discharge for large intestinal volvulus was 100%, versus 16% for small intestinal volvulus.

Non-Hodgkin Lymphomas (NHL) appear with the malign transformation of mature lymphocytes. Intestinal perforations are one of the most well-known complications of NHLs. In this review, a 29-year-old male patient who was diagnosed with NHL with gastrointestinal involvement that developed intestinal perforation after chemotherapy is presented. A 29-year-old male patient who received systemic chemotherapy in another healthcare center due to Major B-Cell Lymphoma was examined because he had stomachache after the treatment. The patient was urgently taken to operation. In the exploration, there were partly mass lesions in all small intestine segments. It was determined that one of the lesion was perforated. Small intestine resection was applied. The pathology report on resection material was reported as High Grade Major B-Cell Lymphoma. In the treatment of Lymphoma with intestinal B-Cells, there is no consensus because this disease is rarely observed. Perforation may appear as a complication of the chemotherapy. Depending on the steroids given to the patient, perforation may develop, and the clinical symptoms may be masked. It must be born in mind that there may be intestinal involvement in patients diagnosed with NHL, and intestinal perforation may develop due to chemotherapy. Copyright © 2017 The Authors.

A 1-year-old boy with no underlying disorder presented with non-bilious vomiting since 4 days before admission. He was referred to our hospital and was diagnosed with a small bowel obstruction due to an intraabdominal tumor. Laparotomy revealed an intestinal volvulus with a soft and lobulated tumor arising from the mesentery. The resected tumor with a small part of the small bowel was diagnosed as lipoblastoma histologically. From a literature review, mesenteric lipoblastoma with an intestinal volvulus showed different characteristics such as greater frequency of vomiting and less frequency of abdominal mass as clinical symptoms, and the size of the tumor was smaller than that of the tumor without the intestinal volvulus.

The distribution of radioactivity after the oral administration of sucralfate labelled with technetium-99m was studied in 33 patients with Crohn's disease (13 adults, 20 children), 10 with ulcerative colitis (four adults), and 29 controls (23 with upper intestinal disease, four irritable bowel, one hypolactasia, and one malrotation of the gut). Positive scans were obtained in all patients with ulcerative colitis and 29 of 31 with active Crohn's disease. The scans of two patients with inactive Crohn's disease were negative. There were two false negative scans in patients with Crohn's colitis and one false positive scan. Overall, sensitivity was 95% and specificity 97%. Comparison with radiology in 39 patients showed similar distribution of disease in 24 and more extensive disease in 12. The scan was inexpensive, simple to perform, well tolerated, allowed small and large bowel to be visualised simultaneously, and used a lower dose of radiation than barium studies. It may prove useful as a screening test for inflammatory bowel disease and in the serial assessment of disease activity. Images FIG 1 FIG 2 FIG 3 FIG 4 PMID:3933613

Intestinal volvulus is a life-threatening emergency requiring prompt surgical management. Prenatal intestinal volvulus is rare, and most are secondary to intestinal atresia, mesenteric defect or without any underlying cause. Cystic fibrosis (CF) is known to cause digestive tract disorders. After birth, 10-15% of newborns with CF may develop intestinal obstruction within a few days of birth because of meconial ileus. 1 This obstruction is a result of dehydrated thickened meconium obstructing the intestinal lumen. We report two cases of fetuses with prenatal diagnosis of segmental volvulus in whom CF was diagnosed. 2016 BMJ Publishing Group Ltd.

Intestinal lymphangiectasia (IL) is a rare disease characterized by dilated lymphatic vessles in the intestinal wall and small bowel mesentery which induce loss of protein and lymphocytes into bowel lumen. Because it most often occurs in the intestine and cannot be detected by upper gastroendoscopy or colonoscopy, and the value of common image examinations such as X-ray and computerized tomography (CT) are limited, the diagnosis of IL is difficult, usually needing the help of surgery. Capsule endoscopy is useful in diagnosing intestinal diseases, such as IL. We here report a case of IL in a female patient who was admitted for the complaint of recurrent edema accompanied with diarrhea and abdominal pain over the last twenty years, and aggravated ten days ago. She was diagnosed by M2A capsule endoscopy as a primary IL and confirmed by surgical and pathological examination.

Abstract The aim of this prospective study was to test a mathematical method of measuring the malrotation of pediatric distal radius fractures (PDRFs) from direct radiographs. A total of 70 pediatric patients who presented at the Emergency Department with a distal radius fracture were evaluated. For 38 selected patients conservative treatment for PDRF was planned. Anteroposterior and lateral radiographs were taken of all of the patients for comparison before and after reduction. Radius bone diameters were measured in the coronal and sagittal planes on the healthy and fractured sides. Using the diameter values on the healthy side and the new diameter values on the fractured side in the rotation formula, the degree of malrotation between the fracture ends was calculated. The mean follow-up period was 13.5 months. Patients’ mean age was 10.00 ± 3.19 years (range, 4–12 years). The rotation degree in the sagittal plane significantly differed between the proximal (26.52°±2.84°) and distal fracture ends (20.96°±2.73°) (P = 0.001). The rotation degree in the coronal plane significantly differed between the proximal (26.70°±2.38°) and distal fracture ends (20.26°±2.86°) (P = 0.001). The net rotation deformity of the fracture line was determined to be 5.55°± 3.54° on lateral radiographs and 5.44°± 3.35° on anteroposterior radiographs, no significant difference was observed between measurements (P >0.05). The malrotation deformity in PDRF occurs with greater rotation in the proximal fragment than in the distal fragment. The net rotation deformity created between the fracture ends can be calculated on direct radiographs. Level of Evidence: Diagnostic, Level II PMID:27149480

A 31-year-old man has visited our hospital, complaining diarrhea and leg edema. Blood test showed hypoalbuminea, but we couldn't find the reason by several examinations. Therefore, we performed double balloon enteroscopy, and intestinal lymphangiectasia was diagnosed histologically by biopsy. It's useful and effective to perform double balloon enteroscopy and histological examination for the unknown origin case of protein loosing enteropathy.

Primary intestinal lymphangiectasia (PIL), Waldmann's disease, is a rare disorder of unknown etiology characterized by dilated intestinal lacteals leading to lymph leakage into the small-bowel lumen and responsible for protein-losing enteropathy leading to lymphopenia, hypoalbuminemia and hypogammaglobulinemia. PIL is generally diagnosed before 3 years of age but may be diagnosed in older patients. The main symptom is bilateral lower limb edema. Edema may be moderate to severe including pleural effusion, pericarditis or ascites. Protein-losing enteropathy is confirmed by the elevated 24-h stool α1-antitrypsin clearance and diagnosis by endoscopic observation of intestinal lymphangiectasia with the corresponding histology of biopsies. Videocapsule endoscopy may be useful when endoscopic findings are not contributive. Several B-cell lymphomas of the gastrointestinal tract or with extra-intestinal localizations were reported in PIL patients. A long-term strictly low-fat diet associated with medium-chain triglyceride and liposoluble vitamin supplementation is the cornerstone of PIL medical management. Octreotide, a somatostatin analog, have been proposed with an inconsistent efficacy in association with diet. Surgical small-bowel resection is useful in the rare cases with segmental and localized intestinal lymphangiectasia. A prolonged clinical and biological follow-up is recommended.

To determine dysplasia and cancer in the 1991-2004 European Collaborative Inflammatory Bowel Disease (EC-IBD) Study Group cohort. A patient questionnaire and a physician per patient form were completed for each of the 1,141 inflammatory bowel disease patients (776 ulcerative colitis/365 Crohn's disease) from 9 centers (7 countries) derived from the EC-IBD cohort. Rates of detection of intestinal cancer and dysplasia as well as extra-intestinal neoplasms were computed. Patient follow-up time was 10.3 +/- 0.8 (range 9.4-11) years. The mean age of the whole group of IBD patients was 37.8 +/- 11.3 (range 16-76) years. Thirty-eight patients (3.3%; 26 with ulcerative colitis/12 with Crohn's disease, 21 males/17 females, aged 61.3 +/- 13.4, range 33-77 years), were diagnosed with 42 cancers. Cancers occurred 5.4 +/- 3.3 (range 0-11) years after inflammatory bowel disease diagnosis. Colorectal cancer was diagnosed in 8 (1 Crohn's disease and 7 ulcerative colitis patients--0.3 and 0.9% of the Crohn's disease and ulcerative colitis cohort, respectively) of 38 patients and 30 cancers were extra-intestinal. Four of 38 patients (10.5%) were diagnosed as having 2 cancers and they were younger compared to patients with one cancer (p = 0.0008). There was a trend for a higher prevalence of intestinal cancer in the northern centers (0.9%) compared to southern centers (0.3%, p = NS). Southern centers had more cases of extra-intestinal cancer compared to northern centers (2 vs. 3.8%, p = 0.08). Ten patients (0.9%; 8 with ulcerative colitis/2 with Crohn's disease, 8 males, aged 62.3 +/- 14.1 years) had colorectal dysplasia. In the first decade of the EC-IBD Study Group cohort follow-up study, the prevalence of cancer was as expected with most patients having a single neoplasm and an extra-intestinal neoplasm. In northern centers there was a trend for more intestinal cancers, while in southern centers there was a trend for more extra-intestinal cancers compared to northern centers. 2007 S.

The aim of this study was to assess the epidemiology of intestinal parasitoses during a 5-year period in patients attending a tertiary-care hospital in a non-endemic setting. In the period 2006-2010, 15,752 samples from 8,886 patients with clinically suspected parasitosis were subjected to macroscopic and microscopic examination, to parasitic antigen detection assays, and to cultures for protozoa and nematodes. Real-time PCR assays for the differentiation of Entamoeba histolytica and E. dispar and for the detection of Dientamoeba fragilis were also used.A statistical analysis evaluating the demographic data of the patients with intestinal parasitic infections was performed. Intestinal parasitic infections were diagnosed in 1,477 patients (16.6% prevalence), mainly adults and immigrants from endemic areas for faecal-oral infections; protozoa were detected in 93.4% and helminths in 6.6% of the cases, the latter especially in immigrants. Blastocystis hominis was the most common intestinal protozoan, and G. intestinalis was the most frequently detected among pathogenic protozoa, prevalent in immigrants, males, and pediatric patients. Both single (77.9%) and mixed (22.1%) parasitic infections were observed, the latter prevalent in immigrants. Despite the importance of the knowledge about the epidemiology of intestinal parasitoses in order to adopt appropriate control measures and adequate patient care all over the world, data regarding industrialized countries are rarely reported in the literature. The data presented in this study indicate that intestinal parasitic infections are frequently diagnosed in our laboratory and could make a contribution to stimulate the attention by physicians working in non-endemic areas on the importance of suspecting intestinal parasitoses.

Malrotation volvulus in a neonate: a novel surgical approach.

A newborn presented with bilious vomiting secondary to a malrotation and presumed perinatal-onset volvulus. Laparotomy was performed at 20 h of age at which the volvulus was derotated. Nevertheless the small but not the large bowel appeared to be completely ischaemic and non-viable. A second-look laparotomy was performed 24 h later with no significant improvement. In a new approach to the problem, nothing further was done and the child was left alone on parenteral nutrition and naso-gastric aspiration for 11 weeks. Further exploration showed that 40 cm of small bowel had survived intact and restorative surgery was carried out. Parenteral nutrition was discontinued after 9 months and the child, now aged 3.5 years, is thriving.

Primary intestinal lymphangiectasia is a rare congenital disease described by Waldmann in 1961 that is a consequence of obstruction of the lymphatic drainage of the small bowel with secondary lymph vessel dilation. This distorts the architecture of the villi and causes a leakage of lymph into the intestinal lumen, resulting in protein-losing enteropathy and malabsorption. To describe the clinical, biochemical, radiologic, endoscopic, and histologic characteristics in children with primary intestinal lymphangiectasia. A retrospective observational, descriptive, cross-sectional study was conducted that reviewed the case records of children diagnosed with primary intestinal lymphangiectasia that were seen at the Department of Gastroenterology and Nutrition of the Instituto Nacional de Pediatría within the time frame of January 1, 1992 to September 30, 2012. Four patients were found that presented with primary intestinal lymphangiectasia. Three of them had been diagnosed before 3 years of age. All the patients presented with chronic diarrhea, edema, lymphopenia, hypocalcemia, and hypogammaglobulinemia, and 3 patients presented with hypocholesterolemia. Bowel transit time, endoscopy, and intestinal biopsies were characteristic of this pathology. Intestinal lymphangiectasia should be suspected when there is a clinical picture of chronic diarrhea and protein-losing enteropathy accompanied with edema at any level, as well as hypoalbuminemia, hypocalcemia, lymphopenia, hypogammaglobulinemia, and hypocholesterolemia, which are the main biochemical findings of this pathology. All children presenting with intestinal lymphangiectasia should undergo an upper gastrointestinal series with bowel transit time and endoscopy with biopsies taken at the level of the duodenum. Treatment includes diet and the periodic administration of albumin and gamma globulin. Copyright © 2013 Asociación Mexicana de Gastroenterología. Published by Masson Doyma México S.A.

A 47-yr-old man with hepatitis B virus associated liver cirrhosis was admitted to our hospital with diarrhea and generalized edema and diagnosed as protein-losing enteropathy due to intestinal lymphangiectasia by intestinal biopsy and 99mTc albumin scan. During hospitalization, he received subcutaneous octreotide therapy. After 2 weeks of octreotide therapy, follow-up albumin scan showed no albumin leakage, and the serum albumin level was sustained. We speculate that liver cirrhosis can be a cause of intestinal lymphangiectasia and administration of octreotide should be considered for patients with intestinal lymphangiectasia whose clinical and biochemical abnormalities do not respond to a low-fat diet.

Paracoccidioidomycosis is a common deep fungus infection in South America, particularly in Brazil. It is acquired through inhalation and primary involvement of lungs. Subsequently, dissemination may occur and oral mucosa is frequently affected and actually, in most of the cases the diagnosis is established because of the oral lesions. Thus, the role of the dentist is fundamental to correct diagnosis. However, the involvement of intestine is rarely reported. The current case describes a 36-year-old man who presented abdominal pain and intestinal constipation, being suspected and then confirmed as paracoccidioidomycosis after already be diagnosed with this disease by a dentist through oral manifestations.

Intestinal parasitoses in a tertiary-care hospital located in a non-endemic setting during 2006–2010

PubMed Central

2014-01-01

Background The aim of this study was to assess the epidemiology of intestinal parasitoses during a 5-year period in patients attending a tertiary-care hospital in a non-endemic setting. Methods In the period 2006–2010, 15,752 samples from 8,886 patients with clinically suspected parasitosis were subjected to macroscopic and microscopic examination, to parasitic antigen detection assays, and to cultures for protozoa and nematodes. Real-time PCR assays for the differentiation of Entamoeba histolytica and E. dispar and for the detection of Dientamoeba fragilis were also used. A statistical analysis evaluating the demographic data of the patients with intestinal parasitic infections was performed. Results Intestinal parasitic infections were diagnosed in 1,477 patients (16.6% prevalence), mainly adults and immigrants from endemic areas for faecal-oral infections; protozoa were detected in 93.4% and helminths in 6.6% of the cases, the latter especially in immigrants. Blastocystis hominis was the most common intestinal protozoan, and G. intestinalis was the most frequently detected among pathogenic protozoa, prevalent in immigrants, males, and pediatric patients. Both single (77.9%) and mixed (22.1%) parasitic infections were observed, the latter prevalent in immigrants. Conclusions Despite the importance of the knowledge about the epidemiology of intestinal parasitoses in order to adopt appropriate control measures and adequate patient care all over the world, data regarding industrialized countries are rarely reported in the literature. The data presented in this study indicate that intestinal parasitic infections are frequently diagnosed in our laboratory and could make a contribution to stimulate the attention by physicians working in non-endemic areas on the importance of suspecting intestinal parasitoses.

Primary intestinal lymphangiectasia (Waldmann's disease).

Vignes, Stéphane; Bellanger, Jérôme

2008-02-22

Primary intestinal lymphangiectasia (PIL) is a rare disorder characterized by dilated intestinal lacteals resulting in lymph leakage into the small bowel lumen and responsible for protein-losing enteropathy leading to lymphopenia, hypoalbuminemia and hypogammaglobulinemia. PIL is generally diagnosed before 3 years of age but may be diagnosed in older patients. Prevalence is unknown. The main symptom is predominantly bilateral lower limb edema. Edema may be moderate to severe with anasarca and includes pleural effusion, pericarditis or chylous ascites. Fatigue, abdominal pain, weight loss, inability to gain weight, moderate diarrhea or fat-soluble vitamin deficiencies due to malabsorption may also be present. In some patients, limb lymphedema is associated with PIL and is difficult to distinguish lymphedema from edema. Exsudative enteropathy is confirmed by the elevated 24-h stool alpha1-antitrypsin clearance. Etiology remains unknown. Very rare familial cases of PIL have been reported. Diagnosis is confirmed by endoscopic observation of intestinal lymphangiectasia with the corresponding histology of intestinal biopsy specimens. Videocapsule endoscopy may be useful when endoscopic findings are not contributive. Differential diagnosis includes constrictive pericarditis, intestinal lymphoma, Whipple's disease, Crohn's disease, intestinal tuberculosis, sarcoidosis or systemic sclerosis. Several B-cell lymphomas confined to the gastrointestinal tract (stomach, jejunum, midgut, ileum) or with extra-intestinal localizations were reported in PIL patients. A low-fat diet associated with medium-chain triglyceride supplementation is the cornerstone of PIL medical management. The absence of fat in the diet prevents chyle engorgement of the intestinal lymphatic vessels thereby preventing their rupture with its ensuing lymph loss. Medium-chain triglycerides are absorbed directly into the portal venous circulation and avoid lacteal overloading. Other inconsistently effective treatments have been proposed for PIL patients, such as antiplasmin, octreotide or corticosteroids. Surgical small-bowel resection is useful in the rare cases with segmental and localized intestinal lymphangiectasia. The need for dietary control appears to be permanent, because clinical and biochemical findings reappear after low-fat diet withdrawal. PIL outcome may be severe even life-threatening when malignant complications or serous effusion(s) occur.

Crohn disease has low prevalence in Sri Lanka while compared to the West, while intestinal tuberculosis is common in the region. Since clinical, endoscopic and investigation features of Crohn disease overlap with intestinal tuberculosis, differentiating these two conditions becomes a dilemma for the clinician in the intestinal tuberculosis endemic setting. An 18-year old Sri Lankan Muslim female presented with chronic abdominal pain and weight loss. Colonoscopy revealed an ulcerated ileocaecal valve and a terminal ileal stricture. Biopsy confirmed Crohn disease with no supportive features to suggest intestinal tuberculosis. Despite treatment with adequate immunosuppression she failed to improve and underwent a limited right hemicolectomy and terminal ileal resection. Histology confirmed intestinal tuberculosis and she made full recover with 6 months of anti-tuberculosis treatment. This case illustrates the importance of reviewing the diagnosis to include intestinal tuberculosis in an endemic setting, when already diagnosed Crohn disease is treatment refractory.

The 3-year survival after small bowel transplantation (SBTx) has improved to between 73% and 88%. Impaired venous access for parenteral nutrition can be an indication for SBTx in children with chronic intestinal failure. To report our experience in management of children with extreme end-stage venous access. The study consisted of 6 children (all boys), median age of assessment 27 months (range, 13-52 months), diagnosed with total intestinal aganglionosis (1), protracted diarrhea (1), and short bowel syndrome (4), of which gastroschisis (2) and malrotation with midgut volvulus (2) were the causes. All had a documented history of more than 10 central venous catheter insertions previously. All had venograms, and 1 child additionally had a magnetic resonance angiogram to evaluate venous access. Five of 6 presented with thrombosis of the superior vena cava (SVC) and/or inferior vena cava. Venous access was reestablished as follows: transhepatic venous catheters (5), direct intra-atrial catheter via midline sternotomy (4), azygous venous catheters (2), dilatation of left subclavian vein after passage of a guide wire and then placing a catheter to reach the right atrium (1), radiological recanalization of the SVC and placement of a central venous catheter in situ (1), and direct puncture of SVC stump(1). Complications included serous pleural effusion after direct intra-atrial line insertion, which resolved after chest drain insertion (1), displacement of transhepatic catheter needing repositioning (2), and SVC stent narrowing requiring repeated balloon dilatation. Four children with permanent intestinal failure on assessment were offered SBTx, 3 of which were transplanted and were established on full enteral nutrition; the family of 1 child declined the procedure. In the remaining 2 children in whom bowel adaptation was still a possibility, attempts were made to provide adequate central venous access as feeds and drug manipulations were undertaken. One of them received liver and SBTx nearly 3 years after presenting with end-stage central venous access, because attempts to achieve independence from parenteral nutrition had failed. The other child died immediately after a transhepatic venous catheter placement, possibly from a nutritional depletion syndrome as no physical cause of death was found. Direct intra-atrial catheters in transplanted children proved to be adequate for the management of uncomplicated transplantation, although the usual infusion protocol had to be modified considerably, and the lack of access would have been critical if massive blood transfusion had been required during the transplant procedure. It was possible to reestablish central venous access in all cases. However, this was time consuming and difficult to assemble a skilled team consisting of one of more: surgeon, cardiologist, interventional radiologist, and transplant anesthetist. Small bowel transplantation is easier and safer with adequate central venous access, and we advocate liaison with an SBTx center at an early stage.

This paper presents the case of a 63 year old female with a severe coxarthrosis. She got a robot assited implantation of a cementless hip prosthesis (Osteolock, Stryker-Howmedica, Mühlheim). As operation robot the CASPAR-System (Orto-Maquet, Rastatt) was used. Initially, the clinical progress of the patient was fine. She was nearly painfree within 14 days and showed an acceptable range of motion in the operated joint (flexion/ extension 90 degrees /05 degrees /00 degrees ). She was mobilized with crutches and 15 kg weight bearing at the operated leg. 3 weeks postoperative the patient complaint about increasing pain without trauma or intensification of the weight bearing. X-rays showed not only a dislocated fracture of the lesser trochanter, but also a sinking combined with a malrotation of the stem. A revision operation was necessary,where we implanted a cemented stem. Now clinical progress was completely satisfying.

A German shepherd dog was presented two months after surgery for correction of acute gastric dilatation volvulus. The dog had been diagnosed with exocrine pancreatic insufficiency. Radiographs revealed marked gaseous distension of one loop of intestine with a generalised increase in intestinal gas content. A 360 degrees anticlockwise rotation of the descending and transverse colon, around the longitudinal axis of the mesocolon, was diagnosed at exploratory coeliotomy. The transverse and descending colon appeared uniformly necrotic and an end-to-end colo-colic resection and anastomosis was performed. The dog initially made satisfactory postoperative progress but was euthanased on the third postoperative day after it developed an intestinal intussusception.

Although paradoxical virological and immunological response after HAART has been well studied, intestinal lymphangiectasia (IL) in HIV-1 infected patients has not previously described. To describe HIV patients who developed IL. Clinical Case series. 4 patients with HIV and IL diagnosis based on clinical, endoscopic and pathological findings. All four cases had prior mycobacterial infections with abdominal lymph node involvement and a very low CD4 cell count nadir. They developed intestinal lymphangiectasia despite appropriate virological suppression with HAART and repeatedly negative mycobacterial cultures. Two patients were clinically symptomatic with oedemas, ascites, diarrhoea, asthenia, weight loss; but the other two were diagnosed with malabsorption as a result of laboratory findings, with hypoproteinemia and hypoalbuminemia. Three of them were diagnosed by video capsule endoscopy. IL should be considered in HIV-1 infected patients who present with clinical or biochemical malabsorption parameters when there is no immunological recovery while on HAART.

Small intestinal volvulus is a rare complication following Roux-en-Y anastomosis. A 63-year-old woman was diagnosed with small intestinal volvulus following laparotomy for clear cell carcinoma of the endometrium. Her past medical history included a total gastrectomy and antecolic Roux-en-Y anastomosis for Duke's B gastric carcinoma. Operative findings were of transmesenteric herniation of the ileum through the Roux-en-Y small intestinal mesenteric window, with metastatic deposits fixing the hernia at its base to create a volvulus. The proximal transverse colon was very dilated and thin due to partial obstruction by the volvulus. Her treatment involved adhesiolysis and unraveling of the small intestinal volvulus. This is the first case report of a small intestinal volvulus following a Roux-en-Y anastomosis involving a metastatic gynacological malignancy.

The prevalence of anisakiasis is rare in the United States and Europe compared with that in Japan, with few reports of its presentation in the emergency department (ED). This study describes the clinical, hematologic, computed tomographic (CT) characteristics, and treatment in gastric and small intestinal anisakiasis patients in the ED. We retrospectively reviewed the data of 83 consecutive anisakiasis presentations in our ED between 2003 and 2012. Gastric anisakiasis was endoscopically diagnosed with the Anisakis polypide. Small intestinal anisakiasis was diagnosed based on both hematologic (Anisakis antibody) and CT findings. Of the 83 cases, 39 had gastric anisakiasis and 44 had small intestinal anisakiasis based on our diagnostic criteria. Although all patients had abdominal pain, the gastric anisakiasis group developed symptoms significantly earlier (peaking within 6 hours) than the small intestinal anisakiasis group (peaking within 48 hours), and fewer patients with gastric anisakiasis needed admission therapy (5% vs 57%, P<.01). All patients in the gastric and 40 (91%) in the small intestinal anisakiasis group had a history of raw seafood ingestion. Computed tomographic findings revealed edematous wall thickening in all patients, and ascites and phlegmon of the mesenteric fat were more frequently observed in the small intestinal anisakiasis group. In the ED, early and accurate diagnosis of anisakiasis is important to treat and explain to the patient, and diagnosis can be facilitated by a history of raw seafood ingestion, evaluation of the time-to-symptom development, and classic CT findings.

The aim of this study was to describe the prevalence of esophageal atresia/stenosis and small intestinal atresia/stenosis in Nagano, Japan, together with associated anomalies, prenatal diagnosis and survival. A population-based cohort study of the prevalence of esophageal atresia/stenosis and small intestinal atresia/stenosis was conducted in Nagano in January 1993-December 2011. The Mann-Whitney test, χ(2) test and Kruskal-Wallis test were used to compare variables. P < 0.05 was considered statistically significant. In total, 74 cases of esophageal atresia/stenosis and 87 cases of small intestinal atresia/stenosis (31 duodenal, 56 jejuno-ileal) were identified. Prevalences were 1.97 for esophageal atresia/stenosis and 2.23 for small intestinal atresia/stenosis (0.83 for duodenal atresia/stenosis and 1.49 for jejuno-ileal atresia/stenosis) per 10,000 births, respectively. The prevalence of esophageal atresia/stenosis increased significantly from 1993-2001 to 2002-2011 (relative risk [RR], 1.6), as did the prevalences of duodenal atresia/stenosis (RR, 2.2) and jejuno-ileal atresia/stenosis (RR, 3.1). Chromosomal anomalies, particularly trisomy 21, were seen significantly more often in association with duodenal atresia/stenosis (55%) than with esophageal atresia/stenosis (28%, P < 0.01) or jejuno-ileal atresia/stenosis (2%, P < 0.01). The proportion of patients associated with prenatally diagnosed chromosomal anomaly was higher compared to postnatal diagnosis (P < 0.01) in the esophageal atresia/stenosis group. The prevalence of esophageal and small intestinal atresia/stenosis increased significantly from 1993-2001 to 2002-2011. Prenatally diagnosed esophageal atresia/stenosis is associated with multiple anomalies, particularly chromosomal anomalies, compared to other small intestine atresia/stenosis. © 2014 Japan Pediatric Society.

Intestinal tuberculosis (TB) was recognized as the most common complication with a high frequency of active pulmonary TB during the TB epidemic period. However, intestinal TB has become a rare disease, and intestinal perforation due to intestinal TB is extremely rare. We herein report two cases of tuberculous intestinal perforation. A 41-year-old man was admitted to our hospital complaining of persistent cough and anorexia. He was in poor nutritional condition, and his body mass index (BMI) and prognostic nutrition index (PNI) were 13.4 and 36.4, respectively. He was diagnosed with pulmonary TB and received anti-TB therapy. On the 51st day of hospitalization, he developed intestinal perforation. Pathologically caseating epithelioid granulomas were noted at the ulcer lesion. A 61-year-old man was admitted to our hospital due to miliary TB caused by intestinal TB. He had taken oral immunosuppressive drugs and steroids for dermatomyositis over the previous eight years and had a poor nutritional condition, with a BMI of 13.4 and a PNI of 14.4. While receiving anti-TB therapy, he developed intestinal perforation on the 97th day of hospitalization. The patient's poor nutritional condition and immune reconstitution may have contributed to the intestinal perforation.

To describe signalment, clinical findings, imaging and treatment of intestinal sand impaction in the dog. Medical records of dogs with radiographic evidence of small intestinal sand impaction were reviewed. Sand impaction resulting in small intestinal obstruction was diagnosed in eight dogs. All dogs presented with signs of vomiting. Other clinical signs included anorexia, lethargy and abdominal pain. Radiographs confirmed the presence of radio-opaque material consistent with sand causing distension of the terminal small intestine in all dogs. Four dogs were treated surgically for their impaction and four dogs were managed medically. Seven of the eight dogs survived. Both medical and surgical management of intestinal sand impaction in the dog can be effective and both afford a good prognosis for recovery.

We sought to use computed tomography (CT) data to support the correct differential diagnosis of patients with spontaneous intramural hematomas of the gastrointestinal tract, to aid in the clinical management of those using oral anticoagulants. Patient data were retrospectively analyzed and patients were divided into two groups. The first group contained 10 patients (5 females, 5 males, median age 65 years [range 35-79 years]) who had been diagnosed with spontaneous intramural hematomas of the gastrointestinal tract. The second group contained nine patients (5 females, 4 males, median age 41 years [range 24-56 years]) who exhibited intestinal wall thickening on CT, and who had been diagnosed with ulcerative colitis, Crohn's disease, ameboma, and lymphoma. The enhancement patterns in the CT images of the two groups were compared by an experienced and inexperienced radiologist. The differences in values were subjected to ROC analysis. Inter-observer variability was excellent (0.84) when post-contrast CT images were evaluated, as were the subtraction values (0.89). The subtracted values differed significantly between the two groups (p=0.0001). A cutoff of +31.5 HU was optimal in determining whether a hematoma was or was not present. Contrast enhancement of an intestinal wall hematoma is less than that of other intestinal wall pathologies associated with increased wall thickness. If the post-contrast enhancement of a thickened intestinal wall is less than +31.5 HU, a wall hematoma is possible. © Acta Gastro-Enterologica Belgica.

Congenital intestinal lymphangiectasia is a disease which leads to protein losing enteropathy. Tortuous, dilated lymphatic vessels in the intestinal wall and mesenterium are typical features of the disease. Clinical manifestations include malabsorption, diarrhea, steatorrhea, edema and effusions. Specific diet and medication are required for disease control. A 19-year old male patient was hospitalized due to diarrhea, abdominal swelling, weariness and fatigue. Physical examination revealed growth impairment, ascites, and lymphedema of the right hand and forearm. Laboratory assessment indicated iron deficiency anaemia, lymphopenia, malabsorption, inflammatory syndrome, and urinary infection. Enteroscopy and video capsule endoscopy demonstrated dilated lymphatic vessels in the small intestine. The diagnosis was confirmed by intestinal biopsy. The patient was put on high-protein diet containing medium-chain fatty acids, somatotropin and supportive therapy. Congenital intestinal lymphangiectasia is a rare disease, usually diagnosed in childhood. Early recognition of the disease and adequate treatment can prevent development of various complications.

Small bowel volvulus is a rare cause of intestinal obstruction in adult patients. This disease is more common in children and its aetiology and management is different to that in adults. A 30 year-old male with sarcoidosis presents with acute abdomen and clinical data of intestinal obstruction. Small bowel volvulus is diagnosed by a contrast abdominal tomography and an exploratory laparotomy is performed with devolvulation and no intestinal resection. In the days following surgery, he developed a recurrent small bowel volvulus, which was again managed with surgery, but without intestinal resection. Medical treatment for sarcoidosis was started, and with his clinical progress being satisfactory,he was discharged to home. Making an early and correct diagnosis of small bowel volvulus prevents large intestinal resections. Many surgical procedures have been described with a high rate of complications. Therefore, conservative surgical management (no intestinal resection) is recommended as the best treatment with the lowest morbidity and mortality rate.

We report an unusual case of a strangulated internal hernia resulting from a right paraduodenal fossa hernia (PDH) in the context of bowel malrotation. There are few documented cases of PDHs associated with a concomitant gut malrotation. Emergency laparotomy was performed based on clinical and radiological. Intraoperatively, the proximal jejunum was seen to enter a hernia sac formed by an aberrant duodenojejunal flexure located to the right of the aorta. This was presumed to be a strangulated internal hernia of the paraduodenal recess in a malrotated gut. The hernia neck was widened and the sac obliterated to allow reduction of the contents. On reduction and warming, the insulted small bowel appeared viable and returned to the abdominal cavity without resection. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

Congenital intestinal lymphangiectasia is a rare disease in childhood, which may already cause protein-losing enteropathy in newborns. This is a case report of an infant with generalized edema and protein-losing enteropathy, in whom intestinal lymphangiectasia was diagnosed at the age of two months. Following repetitive intravenous albumin und gamma globulin infusions, the elimination of long-chain fats from the diet and the substitution with medium-chain triglycerides (MCT) led to an improvement of the protein-losing enteropathy. In newborns with low level of serum protein and edema protein-losing enteropathy caused by congenital lymphangiectasia might be considered as a differential diagnosis.

Perna canaliculus and the Intestinal Microbiome.

Natural medicines are often an attractive option for patients diagnosed with chronic conditions. Three main classes of bioactives that have been reported from marine mussel extracts include proteins, lipids and carbohydrates. Commercially, the most relevant species of marine mollusks belong to two genera, Perna and Mytilus. Specifically, the Perna canaliculus species has been repeatedly demonstrated to harbor anti-inflammatory compounds such as omega-3 polyunsaturated fatty acids ( ω -3 PUFAs) that can ameliorate pro-inflammatory conditions, or proteins that can promote thrombin inhibitory activity. Recent clinical studies have posited that extracts from green-lipped mussels may lead to prebiotic activity in the intestinal microbiome that in turn has been reported to improve symptoms of osteoarthritis of the knee. Prebiotics have been reported to favorably interact with the intestinal microbiome through the proliferation of beneficial bacteria in the gut, suppressing exogenous and endogenous intestinal infections and promoting homeostasis by balancing local pro- and anti-inflammatory actions. Bioactive compounds from Perna canaliculus are functional foods and, in this regard, may positively interact with the intestinal microbiome and provide novel therapeutic solutions for intra-intestinal and extra-intestinal inflammatory conditions.

Autoimmune polyglandular syndromes (APS) comprise a wide clinical spectrum of autoimmune disorders. APS is divided into Type I, Type II, Type I and Type IV depending upon the pattern of disease combination. Ghronic diarrhoea is one of the many manifestations of APS and many aetiological factors have been suggested for it. Apart from the established aetiological factors, intestinal lymphangiectasia may be responsible for chronic diarrhea in some cases.Intestinal lymphangiectasia has been reported in Type I APS. We report a case of Type III APS with hypocalcaemia and hypothyroidism who had chronic diarrhea of long duration and was finally diagnosed to have intestinal lymphangiectasia.

Primary intestinal lymphangiectasia (Waldmann's disease) is a rare disease characterized by dilated lymphatics in the small bowel leading to an exudative enteropathy with lymphopenia, hypoalbuminemia and hypogammaglobulinemia. We report the case of a 23 year-old male who presented with chronic anemia and in whom primary intestinal lymphangiectasia was diagnosed. A low-fat diet along with nutritional therapy with medium-chain triglyceride supplementation improved the protein-losing enteropathy, but did not solve the anemia. Octreotide was also unsuccessful, and after attempting angiographic embolization therapy, limited small bowel resection together with antiplasmin therapy managed to correct the anemia and control the exudative enteropathy. Although primary intestinal lymphangiectasia is usually adequately managed by nutritional therapy, complications such as anemia can occur and can prove to be a therapeutic challenge.

Rhizomelic chondrodysplasia punctata (RCP), a rare autosomal recessive disease characterized by a disorder of peroxisome metabolism, has been shown to affect multiple organ systems. A neonate presenting with a colonic perforation in the first few hours of life was subsequently diagnosed with RCP. A literature search revealed no previous reports of intestinal perforation associated with RCP. Intestinal perforation should be added to the list of medical complications associated with RCP.

Active search of celiac disease (CD) among risk groups has significantly increased the scope of known clinical variants. To measure the frequency and clinical characteristics of CD among first degree relatives (FDR) of known celiac cases. Between January 2012-August 2013, 37 patients with celiac disease brought 113 FDR for assessment. Their clinical data was recorded and a blood sample was obtained to measure serum Immunoglobulin A (IgA) levels, anti-transglutaminase (tTG) and anti-endomisial (EMA) antibodies. Cases with positive serology were advised to have an intestinal biopsy. Fourteen relatives (12.4%) had positive serological results and none had IgA deficiency. Among IgA-tTG (-) cases, measurement of IgA/IgG-tTG identified an additional case. Two of the 14 relatives were EMA positive. All 14 cases were advised to have an intestinal biopsy, but only 6 accepted the procedure. In two, the intestinal lesion was classified Marsh ≥ 2 and active CD was diagnosed. Histology in the remaining four was Marsh 0/1 and were diagnosed potential CD, remaining under control, without gluten free diet. Serological prevalence of CD among first degree relatives of known celiac cases was 15 fold greater than in THE general Chilean population, strongly supporting the idea of implementing active search to customary clinical practice. Determination of IgA/IgG-tTG may be useful to improve the yield of active search. Intestinal biopsies were crucial to differentiate active classic CD from potential CD.

Advances in diagnostic techniques and perioperative care have greatly improved the outcome of neonatal surgery. Despite this, disparity still exists in the outcome of neonatal surgery between developed and developing countries. We performed a prospective study of neonates admitted and treated due to surgical congenital diseases and other conditions in our hospital from April 2015 to April 2017. There were 19 (28,7%) females and 47 (70,3%) males in this group. It was found that 41 neonates had 7 days after birth or less by a 62% and 25 with more than 7 days by 38%. The Anorectal malformations (ARM) were the most frequent congenital anomaly in 21 patients (47%), followed by Gastroquises with 7 neonates (10,6%), Omphalocele with 8 (12%), and Oesophagus Atresia in 5 neonates (7,5%). Intestinal Malrotation with midgut volvulus, Pyloric Stenoses and Duodenal Atresia in 4 neonates (6,2 % each). Others alterations such as, Ileal Atresia, Strangulated Inguinal Hernia, Limb Gangrene, Necrotizing Enterocolitis, Sacro Coxigeal Theratoma, Megacolon Aganglionic, Colon perforation, Gastric perforation and Hydromethrocolpus accounted in 13 neonates by 19,7% from the total of patients. Ten babies died (15%). We conclude that Anorectal Malformations, Gastroquises and Omphalocele were the most frequent malformations. Considering the mortality is above the average of developed countries this could be improved by increasing the knowledge about the neonatal surgery characteristics among medical doctors and improving the necessary facilities and back up.

Adhesive small bowel obstruction (ASBO) is a feared complication after abdominal operations in both children and adults. The optimal management of ASBO in the pediatric population is debated. The aim of the present study was to examine the safety and effectiveness of non-operative management in ASBO. A retrospective review of 33 patients who were admitted for ASBO over a 5-year period was carried out. Follow-up data were available for 29 patients. Demographic, clinical, and operative details and outcomes were collected for these patients. Data analysis was done with SPSS version 15.0. P ≤ 0.05 was regarded as significant. Out of 618 abdominal surgeries within the 5-year period, 34 admissions were recorded from 29 patients at the follow-up period of 1-28 months. There were 19 boys (65.5%). The median age of patients was 4.5 years. Typhoid intestinal perforation (n = 7), intussusception (n = 6), intestinal malrotation (n = 5), and appendicitis (n = 4) were the major indications for a prior abdominal surgery leading to ASBO. Twenty-five patients (73.5%) developed SBO due to adhesions within the first year of the primary procedure. Of the 34 patients admitted with ASBO, 18 (53%) underwent operative intervention and 16 (47%) were successfully managed non-operatively. There were no differences in sex (P = 0.24), initial procedure (P = 0.12), age, duration of symptoms, and time to re-admission between the patients who responded to non-operative management and those who underwent operative intervention. However, the length of hospital stay was significantly shorter in the non-operative group (P < 0.0001). Five (14.7%) patients had small bowel resection. A 43-day-old child who initially underwent Ladd's procedure died within 15 h of re-admission while being prepared for surgery, accounting for the only mortality (3.4%). Non-operative management is still a safe and preferred approach in selected patients with ASBO. However, 53% eventually required surgery.

A newborn female was transferred to our hospital presenting with severe respiratory distress. She underwent tracheal intubation and nasogastric tubing. Investigations revealed a congenital extrahepatic portosystemic shunt (CEPS) type 1, biliary atresia, heterotaxia, polysplenia, malrotation and a double aortic arch (DAA). She underwent the Kasai portoenterostomy and the Ladd procedure when she was 29 days old. On postoperative day 20, she developed sudden hematemesis with bright red blood. Endoscopy showed massive bleeding from an esophageal ulcer, and endoscopic therapy was performed successfully. During left thoracotomy, an aortoesophageal fistula (AEF) was detected and repaired by direct suturing. The postoperative course was uneventful. CEPS type 1 is commonly associated with other congenital malformations; however, there have been no previous reports of an association between CEPS and DAA. Nasogastric tube insertion in a patient with DAA can result in catastrophic AEF. The treatment strategy should be carefully considered in patients with CEPS type 1 and multiple congenital fetal anomalies.

Colonic volvulus is a relatively uncommon cause of large bowel obstruction usually involving mobile, intra-peritoneal, colonic segments. Congenital or acquired anatomic variation may be associated with an increased risk of colonic volvulus which can occasionally involve retro-peritoneal segments. We report a case of 54-year-old female who presented to our Institution to perform a plain abdominal film series for acute onset of cramping abdominal pain. Both the upright and supine films showed signs of acute colonic obstruction which was thought to be due to an internal hernia of the transverse colon into the lesser sac. The patient was therefore submitted to a multi-detector contrast-enhanced computed tomography (CT). CT findings were initially thought to be consistent with the presumed diagnosis of internal hernia but further evaluation and coronal reformatting clearly depicted the presence of a colonic volvulus possibly resulting from a retro-gastric colon. At surgery, a volvulus of the ascending colon was found and a right hemi-colectomy had to be performed. However, a non rotated midgut with a right-sided duodeno-jejunal flexure and a left sided colon was also found at laparotomy and overlooked in the pre-operative CT. Retrospective evaluation of CT images was therefore performed and a number of CT signs of intestinal malrotation could be identified.

Intestinal parasitosis are cosmopolitan affections, often related to the fecal peril. However urinary bilharziosis is a disease eliminated in Tunisia. As part of monitoring the emergence and re-emergence of intestinal parasitosis and urinary bilharziasis, foreign students benefit from parasitological systematic monitoring stool and urine during their enrollment to the University. To study the prevalence of various intestinal parasitosis and urinary bilharziasis among non permanent resident students in Tunisia. A retrospective survey was carried at the Laboratory of Parasitology- Mycology of Charles Nicolle Hospital of Tunis during the inscription period of 6 university years 2005-2010. 328 students profited from a parasitological examination of stool and urine. 144 students (43.9%) harbored intestinal parasites. More than one parasite was detected in 69 students (47.9%). Intestinal protozoa were the majority of identified parasites (96.9%). 9.7% of identified parasites were pathogenic. Three cases (0.91%) of urinary bilharziasis were diagnosed. The prevalence of intestinal and urinary parasitism among the "non-permanent residents" students in Tunisia has not changed. This justifies a systematic parasitologic monitoring for students coming from areas of high endemicity of parasitosis in order to avoid the introduction of these.

Primary intestinal lymphangiectasia (PIL) is a rare disorder characterized by dilated intestinal lymphatics and the development of protein-losing enteropathy. Patients with PIL develop hypoalbuminemia, hypocalcemia, lymphopenia and hypogammaglobulinemia, and present with bilateral lower limb edema, fatigue, abdominal pain and diarrhea. Endoscopy reveals diffusely elongated, circumferential and polypoid mucosae covered with whitish enlarged villi, all of which indicate intestinal lymphangiectasia. Diagnosis is confirmed by characteristic tissue pathology, which includes dilated intestinal lymphatics with diffusely swollen mucosa and enlarged villi. The prevalence of PIL has increased since the introduction of capsule endoscopy. The etiology and prevalence of PIL remain unknown. Some studies have reported that several genes and regulatory molecules for lymphangiogenesis are related to PIL. We report the case of a patient with PIL involving the entire small bowel that was confirmed by capsule endoscopy and double-balloon enteroscopy-guided tissue pathology who carried a deletion on chromosome 4q25. The relationship between this deletion on chromosome 4 and PIL remains to be investigated. PMID:22110841

Intestinal parasitic infections in immunocompromised patients can lead to serious complications when not diagnosed and treated early. This study aimed to investigate the frequency of intestinal parasites in cancer patients undergoing chemotherapy in the South of Brazil. Three fecal samples collected from each patient (73 individuals) were processed by Ritchie and Faust techniques and submitted to specific staining methods for intestinal protozoa. A 61.6% parasite and/or commensal positivity was found. Helminths identified were Ascaris lumbricoides (33.3%), Taenia spp. (6.6%), Strongyloides stercoralis (4.4%) and Trichuris trichiura (2.2%). Among protozoans, Giardia lamblia (26.6%), Cryptosporidium spp. (13.3%) and Cystoisospora belli (4.4%) were identified. The presence of Entamoeba coli, Endolimax nana and Entamoeba hartmanni was also recorded. The results obtained warn of the importance of fecal parasitological diagnosis and the use of specific staining methods for the detection of intestinal parasites in cancer patients. These exams should be regularly requested at the patient's first clinic visit, given the high prevalence found in this study and the possible severity of such conditions for these individuals.

Some patients previously diagnosed with irritable bowel syndrome (IBS) may develop microscopic colitis or small intestinal bacterial overgrowth (SIBO). To estimate the prevalence of microscopic colitis and SIBO in patients with IBS, to evaluate the symptoms and the efficacy of treatment. We examined patients with IBS admitted in our clinic during a three-year period. We identified patients with microscopic colitis by performing total colonoscopy with multiple biopsies from normal intestinal mucosa and those with SIBO by performing a H2-breath test with glucose. We compared the symptoms and the effectiveness of the treatment. Out of the 132 patients initially diagnosed with IBS 3% (n=4) had microscopic colitis and 43.9% (n=58) had SIBO. Diarrhea was the main symptom in patients with microscopic colitis and SIBO (p=0.041), while abdominal pain, abdominal bloating and flatulence were prominent in IBS patients (p=0.042; p=0.039; p=0.048). Specific treatment with rifaximin in SIBO patients negativated H2-breath test in 70.9% cases. Patients suspected to have irritable bowel syndrome should be evaluated for microscopic colitis and SIBO. The proper diagnosis and the specific treatment may cure some difficult cases of the so called "irritable bowel syndrome".

Malrotation with a common mesentery is the classical pathology allowing midgut volvulus to occur. There are only a few reports of small bowel volvulus without malrotation or other pathology triggering volvulation. We describe three cases of small bowel volvulus in very premature newborns with a perfectly normal intra-abdominal anatomy and focus on the question, what might have set off volvulation. In 2005 to 2008, three patients developed small bowel volvulus without any underlying pathology. Retrospective patient chart review was performed with special focus on clinical presentation, preoperative management, intraoperative findings, and potential causative explanations. Mean follow-up period was 46 months. All patients were born between 27 and 31 weeks (mean 28 weeks) with a birth weight between 800 and 1,000 g (mean 887 g). They presented with an almost identical pattern of symptoms including sudden abdominal distension, abdominal tenderness, erythema of the abdominal wall, high gastric residuals, and radiographic signs of ileus. All of them were treated with intensive abdominal massage or pelvic rotation to improve bowel movement before becoming symptomatic. Properistaltic maneuvers including abdominal massage and pelvic rotation may cause what we term a "manufactured" volvulus in very premature newborns. Thus, this practice was stopped.

We studied a patient with edema secondary to protein losing enteropathy, and recurrent bouts of bloating and abdominal pain secondary to intestinal subocclusion episodes. After the clinical study, the patient was diagnosed of cryptogenic multifocal ulcerous stenosing enteritis (CMUSE), that is a rare disease, probably caused by mutations in the gene PLA2G4A, and characterized by multiple short stenosis of the small bowel with superficial ulcers, which do not exceed the submucosa layer. Inflammatory bowel disease (Chron's disease), intestinal tuberculosis and intestinal ulcers secondary to non-steroidal anti-inflammatory drugs are the main differential diagnosis. To sum up, physicians should included CMUSE in the differential diagnosis of recurrent abdominal pain, iron deficiency anaemia, occult intestinal bleeding, edema and protein losing enteropathy.

Case report of primary intestinal lymphangiectasia diagnosed in an octogenarian by ileal intubation and by push enteroscopy after missed diagnosis by standard colonoscopy and EGD.

Primary intestinal lymphangiectasia (PIL) is a rare, presumably congenital lesion that is usually diagnosed in patients < 3 years old, is rarely first diagnosed in adulthood, and when first diagnosed in adulthood typically presents with symptoms for many years. Although PIL is often identified by endoscopic abnormalities, it must be emphasized that the jejunoileum/distal duodenum must be intubated for diagnosis because the lesions are present in these regions. This work demonstrates that 1)-PIL can occur in an octogenarian; 2)-shows that the characteristic endoscopic findings are not found at colonoscopy without terminal ileal intubation; and 3)-may be missed at standard EGD without distal duodenal intubation. A patient initially presented at age 83 with symptoms of watery diarrhea, abdominal distention, 5-Kg-weight-gain, and weakness for one month, and had typical clinical findings of PIL including chylous ascites, pleural effusions, bilateral pitting leg edema, hypoalbuminemia, borderline lymphopenia, hypovitaminosis-D, and hypocalcemia. Protein-losing-enteropathy was demonstrated by positive stool tests for alpha-1-antitrypsin. Standard colonoscopy revealed no significant lesions, but terminal ileal intubation during colonoscopy demonstrated creamy-white, punctate, mucosal lesions in terminal ileum, characteristic of lymphangiectasia. EGD with intubation to mid-descending duodenum revealed no significant lesions, but subsequent enteroscopy demonstrated lesions in distal duodenum/proximal jejunum similar to those in terminal ileum characteristic of lymphangiectasia. Histopathologic analysis of lesions of terminal ileum/distal duodenum demonstrated dilated mucosal vessels, confirmed as lymphatic vessels by immunohistochemistry. PIL was diagnosed after excluding secondary causes of intestinal lymphangiectasia. Patient placed on standard PIL diet: oral supplements of medium-chain triglycerides, a high protein diet, supplements of fat-soluble vitamins, and avoiding long-chain fatty acids, with marked clinical improvement. This work shows that: 1)-standard EGD and colonoscopy may miss characteristic lesions of PIL, 2)-enteroscopy or terminal ileal intubation at colonoscopy may be required for the diagnosis because lesions are typically located in distal duodenum/jejunoileum; and 3)-PIL can first present in the very elderly even with symptoms of short duration.

To report and evaluate the application of entire gastrointestinal barium meal combined with multi-temporal abdominal films in the diagnosis of patients with intestinal neuronal dysplasia type B (IND type B). Thirty-six patients with symptoms of long-standing constipation were enrolled in this study. The study took place at the Department of General Surgery, Xiangyang Central Hospital, Hubei Province, China from July 2007 to October 2012. All of them had already been subjected to the tests of barium enema and anorectal manometry and were suspected to be IND type B, but were not confirmed by mucous membrane acetylcholinesterase determination. All underwent the entire gastrointestinal barium meal combined with multi-temporal abdominal films. The data was collected and then analyzed retrospectively. After entire gastrointestinal barium meal combined with multi-temporal abdominal films, 30 out of 36 cases in this group were diagnosed with intestinal neuronal diseases, and then were treated with appropriate surgical treatment. The postoperative pathological diagnosis was IND type B. The other 6 patients in this group still could not be diagnosed explicitly after the test; thus, we treated them with conservative treatment. Entire gastrointestinal barium meal combined with multi-temporal abdominal films has the advantage of being able to test the gastrointestinal transfer capabilities and to find physiological and pathological changes simultaneously. It could provide important proof for the diagnosis of patients with intestinal neuronal dysplasia type B.

Duplications of the alimentary tract are congenital malformations. The ileum is the most commonly affected organ. A lot of duplications are incidentally diagnosed but most of patients present a combination of pain or complications such as obstructive symptoms, intestinal intussusception, perforation or volvulus. We report the case of a 6-years-old girl, with intermittent abdominal pain and vomits for two months long. Laboratory work was completely normal and in the radiology analysis (abdominal sonography and magnetic resonance) a cystic image with intestinal volvulus was observed. The patient underwent laparotomy, Ladd's procedure was done and the cyst was resected. In conclusion, if a patient is admitted with abdominal pain and obstructive symptoms, it is important to consider duplication of the alimentary tract as a possible diagnosis.

Abstract Rationale: Primary intestinal lymphangiectasia (PIL) is a rare, presumably congenital lesion that is usually diagnosed in patients < 3 years old, is rarely first diagnosed in adulthood, and when first diagnosed in adulthood typically presents with symptoms for many years. Although PIL is often identified by endoscopic abnormalities, it must be emphasized that the jejunoileum/distal duodenum must be intubated for diagnosis because the lesions are present in these regions. This work demonstrates that 1)-PIL can occur in an octogenarian; 2)-shows that the characteristic endoscopic findings are not found at colonoscopy without terminal ileal intubation; and 3)-may be missed at standard EGD without distal duodenal intubation. Diagnoses: A patient initially presented at age 83 with symptoms of watery diarrhea, abdominal distention, 5-Kg-weight-gain, and weakness for one month, and had typical clinical findings of PIL including chylous ascites, pleural effusions, bilateral pitting leg edema, hypoalbuminemia, borderline lymphopenia, hypovitaminosis-D, and hypocalcemia. Protein-losing-enteropathy was demonstrated by positive stool tests for alpha-1-antitrypsin. Standard colonoscopy revealed no significant lesions, but terminal ileal intubation during colonoscopy demonstrated creamy-white, punctate, mucosal lesions in terminal ileum, characteristic of lymphangiectasia. EGD with intubation to mid-descending duodenum revealed no significant lesions, but subsequent enteroscopy demonstrated lesions in distal duodenum/proximal jejunum similar to those in terminal ileum characteristic of lymphangiectasia. Histopathologic analysis of lesions of terminal ileum/distal duodenum demonstrated dilated mucosal vessels, confirmed as lymphatic vessels by immunohistochemistry. PIL was diagnosed after excluding secondary causes of intestinal lymphangiectasia. Interventions/Outcomes: Patient placed on standard PIL diet: oral supplements of medium-chain triglycerides, a high protein diet, supplements of fat-soluble vitamins, and avoiding long-chain fatty acids, with marked clinical improvement. Lessons: This work shows that: 1)-standard EGD and colonoscopy may miss characteristic lesions of PIL, 2)-enteroscopy or terminal ileal intubation at colonoscopy may be required for the diagnosis because lesions are typically located in distal duodenum/jejunoileum; and 3)-PIL can first present in the very elderly even with symptoms of short duration.

Fetal intestinal volvulus is a rare life-threatening condition. Late diagnosis of volvulus contributes to high rate of morbidity and mortality. It has variable degrees of presentation and survival. Intrauterine volvulus may be complicated by intestinal atresia due to ischemic necrosis. To our knowledge, there are three reported cases of term fetal demise. We report a case of fetal intestinal volvulus with perinatal survival of the largest term infant described with this complication to date. The volvulus was associated with type 3A jejunal atresia and intestinal pathology was noted on prenatal ultrasound. The infant was born via urgent cesarean delivery at 37(6/7) weeks of gestation and underwent emergent exploratory laparotomy with resection of small bowel and primary end-to-end anastomosis. Intrauterine intestinal volvulus may be suspected on prenatal ultrasound but only definitively diagnosed postnatally. Signs of fetal distress and volvulus are rarely associated with reports of survival in the term fetus. We review reported cases of prenatally suspected volvulus in infants documented to survive past the neonatal period. As fetal volvulus and most intestinal atresias/stenoses manifest during the third trimester, we recommend that the limited fetal anatomical survey during growth ultrasounds at 32 to 36 weeks routinely include an assessment of the fetal bowel.

One of the major health problems among HIV sero-positive patients are superimposed infections due to the deficient immunity. Furthermore, intestinal parasitic (IP) infections, which are also one of the basic health problems in tropical regions, are common in these patients. Infection by opportunistic pathogens, including various forms of intestinal parasites has been the hall mark of HIV since the beginning of the epidemic. To study the prevalence of opportunistic intestinal parasitic infection among HIV patients who are taking antiretroviral treatment (ART) in Jimma, Ethiopia. Patient samples were diagnosed by examination of single stool specimen which was examined as fresh wet mounts, formal-ether concentration technique and modified Ziehl-Neelsen staining technique. Data was obtained from 91 study subjects selected by convenience sampling method. The overall prevalence of intestinal parasitic infections was found to be 39.56%. Eight types of intestinal parasites was identified, the most dominant being, Ascaris lumbricoides, 21.67%, Entamoeba histolytica, 15% and Cryptosporidium parvum 13.33%. The prevalence of opportunistic parasite was 15.38%, the prevalence of non-opportunistic parasite was 20.87% and the prevalence of both opportunistic and non opportunistic was 3.29%. The study indicated that intestinal parasites were still a problem in the study area. Data also showed that among the predisposing factors, habit of hand washing before meal, usage of latrine and duration after treatment was statistically associated with intestinal parasitic infections.

The incidence of Crohn's disease (CD) has been steadily increasing in Korea due to westernized life style and widely used imaging studies such as colonoscopy. There were few studies about the status of longterm trend of CD and intestinal tuberculosis (IT). Therefore, we aimed to evaluate the trend of CD and IT in Korea. We retrospectively reviewed the medical records of newly diagnosed 65 patients with CD and 54 patients with IT at Chonnam National University Hospital between January 1998 and August 2007. Between 1998 and 2002, 16 and 40 patients were newly diagnosed as having CD and IT respectively, but between 2003 and 2007, 39 and 14 patients were newly diagnosed as having CD and IT respectively. CD patients (28.2+/-15.2 years) were younger than IT (46.2+/-18.5 years) (p=0.001). The male to female ratio of CD and IT were 2:1 and 1.1:1, respectively. The most common symptom of CD and IT was abdominal pain. Longitudinal ulceration, hyperemia, luminal narrowing, pseudopolyp, and cobble stone appearance were more common in CD than in IT (p<0.05). While the incidence of CD has increased, the incidence of IT has fallen over the last decade.

Intestinal involvement in endometriosis was first described by Sampson in 1922. The reported incidence ranges between 3% and 37% in patients diagnosed with endometriosis. In literature, there are few studies that correlate the severity of endometriosis (in terms of intestinal infiltration) and its clinical presentation. The aim of this study was to review the correlation between the severity of symptoms, the depth of intestinal wall infiltration, and lymph node involvement in our tertiary referral center. We retrospectively analyzed 553 patients who had undergone intestinal resection for deep infiltrating endometriosis at our institution (Sacro Cuore Negrar Hospital) between 2004 and 2009. Based on intestinal wall infiltration, we divided patients into three groups (Group A: intestinal infiltration that reaches the muscle layer, Group B: infiltration to the submucosa, and Group C: endometriosis reaches the mucosa). Symptoms, intestinal stenosis, and positive lymph nodes were compared in the three groups with the chi-square test. No statistical correlation was found between symptoms and the intestinal wall infiltrations. The three groups were also compared on the basis of positive visceral lymph nodes and we did find a statistical difference (P = .05) in the lymph node count in the two main groups. There seems to be no statistically significant difference in symptoms between patients with different degrees of infiltration. Although visceral lymph node involvement has been occasionally described in literature, we found that it is related to submucosal infiltration.

Our aim was to explore the diagnostic value of fasting citrulline concentrations to detect decreased intestinal energy absorption in patients with recently diagnosed celiac disease (CeD), refractory celiac disease (RCeD), and short bowel syndrome (SBS). Decreased intestinal energy absorption is regarded a marker of intestinal failure. Fasting plasma citrulline concentrations were determined by high performance liquid chromatography (HPLC) in a prospective study of 30 consecutive adult patients (15 CeD, 9 RCeD, and 16 SBS) and 21 healthy subjects. Intestinal energy absorption capacity using bomb calorimetry was determined in all patients and healthy subjects and was regarded as the gold standard for intestinal energy absorption function. The mean fasting plasma citrulline concentration was lower in RCeD patients than in healthy subjects (28.5+/-9.9 vs 38.1+/-8.0 micromol/L, P<0.05) and CeD patients (28.5+/-9.9 vs 38.1+/-6.4 micromol/L, P<0.05), however, clearly within reference values. The mean intestinal energy absorption capacity was lower in SBS patients than in healthy subjects (64.3+/-18.2 vs 90.3+/-3.5%, P<0.001), CeD patients (64.3+/-18.2 vs 89.2+/-3.4%, P<0.001), and the RCeD group (64.3+/-18.2 vs 82.3+/-11.7%, P<0.01). No relation was observed between fasting plasma citrulline concentration and intestinal energy absorption capacity (Pearson r=0.09, P=0.56). The area under the ROC curve for fasting plasma citrulline to detect decreased intestinal energy absorption capacity (i.e., <85%) was 0.50. Fasting plasma citrulline concentrations have poor test characteristics for detection of decreased intestinal energy absorption capacity in patients with enterocyte damage.

To identify the protozoa responsible for intestinal parasitosis diagnosed at Le Dantec University Hospital in Dakar, Senegal. The retrospective study included 2578 patients for whom stool samples were analyzed from 2011 to 2015. The sex ratio was 1.1. Patients' mean age was 28.5 years, with a range of 11 days to 91 years. Direct examination and the Ritchie technique were performed to search for parasites. In total, 317 patients had intestinal protozoa, for a prevalence of 12.3 %. Infections involved one (91%) or two parasites (9%). The most common species found alone were Entamoeba coli (51.5%), E. histolytica/E. dispar (17 %), and Giardia intestinalis (10.5%). The most common associations were E. coli with G. intestinalis (3.6 %) and with E. histolytica (2.4%). These infections affected significantly more outpatients than inpatients (65 %, p = 0.0049) and slightly more women (51.1%, p = 0.22) than men. Adults accounted for 67% of the confirmed intestinal protozoa: 39% aged 31-60 years, 28% aged 15-30, and only 7% older than 60 (p = 0.5). Most of the protozoa isolated were non-pathogenic. However, health education should be promoted in addition to the mass treatment program already begun to limit and even halt the spread of these neglected diseases.

Anatomically shaped cohesive silicone breast implants are frequently used in aesthetic and reconstructive surgery. After successful results with the Style 410 prosthesis, McGhan (Natrelle, Allergan) introduced the Style 510 prosthesis. After using this novel prosthesis, the authors encountered a high number of prosthesis malrotations on self-reported follow-up. Therefore, a retrospective medical record review was performed to determine the prevalence of malrotation of the Style 510 prosthesis. From January of 2005 to December of 2006, 73 (146 prostheses) aesthetic augmentation mammaplasty procedures were performed using Style 510 prostheses. All prostheses were placed subglandularly through an inframammary incision. The postsurgical protocol for the first 3 weeks involved wearing a nonwired compression bra, abstinence from sports activities, and abstinence from heavy labor. Standard follow-up was at 1 week, 3 months, and if necessary. On self-reported follow-up, 8.2 percent of all prostheses were rotated. These rotations all occurred unilaterally after a mean period of 10 months (range, 3 to 19 months). No relation to an inciting incident or prosthesis volume could be found. The number of rotations of the Style 510 prosthesis seen after primary aesthetic breast augmentation is high. An obvious cause of this major problem has not been found. This led the authors to discontinue using the Style 510 prosthesis for primary aesthetic mammary augmentations in their practice.

The profile of intestinal parasitosis was assessed among patients on anticancer chemotherapy in Sana'a city, Yemen during the period from April to December 2011. A total of 206 patients (115 males & 91 females), aged 3 to 18 years with mean of 14.17 +/- 3.13 were subjected to stool examinations by different techniques. The overall rate of intestinal parasites was 63.1%. Cryptosporidium parvum was the highest (30.1%) followed by G. lamblia (18.0%) and then C. cayetanensis (5.3%). Blastocystis hominis and E. histolytica/dispar were detected in 4.9% & 2.4% respectively. E. coli, H. nana and A. lumbricoides were diagnosed in an equal of 1.5% and S. stercoralis was seen in one case only. The majority of infected patients suffered from diarrhea. They showed 4.64 risk of protozoan infections compared to those who passed formed stool with statistically significant difference. Diarrhea was associated with higher risk of cryptosporidiosis and giardiasis (OR = 2.73 & 2.67 respectively). The risk of intestinal parasitosis neither differed significantly with patients' age nor sex.

Background. A novel mutation in the ACTG2 gene is described in a pregnant patient followed up for chronic intestinal pseudoobstruction (CIPO) during pregnancy and her fetus with megacystis microcolon intestinal hypoperistalsis syndrome (MMIHS). Case. 24-year-old gravida 1 para 1 with CIPO and persistent nausea and vomiting in pregnancy, admitted at 28 weeks of gestation. Ultrasound revealed a fetus measuring greater than the 95th percentile, polyhydramnios, and megacystis. At delivery, the newborn was noted to have an enlarged bladder, microcolon, and intolerance of oral intake. Genetic testing of mother and child revealed a novel mutation in the ACTG2 gene (C632F>A, p.R211Q). Conclusion. This is the first case in the literature describing a novel mutation in ACTG2 associated with visceral myopathy affecting both mother and fetus/neonate. Visceral myopathy should be included in the differential diagnosis of megacystis diagnosed by ultrasound, and suspicion should increase with family history of CIPO or MMIHS.

Ninety-one patients with intestinal amebiasis (IA) were studied. All had been long suffering from IA due to the fact that it had not been diagnosed in time. Indications for emergency surgery were profuse hemorrhage, perforation of amebic ulcers, gangrene, and toxic dilatation of the large intestine. Planned operations were made in pseudopolyposis, strictures of the large intestine. Surgical treatment was performed along with specific therapy. Seven patients died due to late diagnosis, ineffective therapy and profound systemic and regional changes caused by these factors. It is necessary to differentiate ulcerative colitis, polyposis, and tumors of the large intestine with IA.

Mesenteric volvulus describes a torsion of the small intestine around the mesenteric root, which can be partial or complete. In dogs, it is an uncommon condition, with German shepherd dogs showing a predisposition. Chronic mesenteric volvulus has also been described. In cats, previous reports have documented two cases of small intestinal volvulus, both diagnosed at necropsy, and a further case of volvulus of the colon in a patient that died after surgery. This report describes two cats with mesenteric volvulus that were successfully treated. To the authors' knowledge, no reports of antemortem diagnosis or treatment of small intestinal volvulus in cats have previously been published. On the basis of the cases presented, it appears that the diagnosis of intestinal volvulus may be more difficult in cats than in dogs, but that the prognosis may not be as poor. Therefore, it is suggested that owners be encouraged to pursue surgery. Copyright © 2010 ISFM and AAFP. Published by Elsevier Ltd. All rights reserved.

Primary intestinal lymphangiectasia is a rare disease of children, which is characterized by chronic diarrhea and complicated with malnutrition, including fat-soluble vitamin deficiency. We report a girl aged 4 years and 8 months who was diagnosed with the disease by endoscopic duodenal biopsy at 8 months of age. She presented initially with chronic diarrhea at 4 months of age. Generalized edema with hypoalbuminemia frequently occurred despite regular albumin supplements. Multiple vitamins initially were not supplied regularly. Episodes of tetany caused by hypocalcemia developed 4 years after the diagnosis of intestinal lymphangiectasia. Imaging study (long-bone X-ray and dual-energy X-ray absorptiometry) revealed low bone density. Complicated vitamin D deficiency [low serum 25-hydroxy vitamin D concentration (< 12.48 mmol/L, the detection limit)] and secondary hyperparathyroidism were confirmed via blood testing. Vitamin D supplementation for 3 months improved her bone density, secondary hyperparathyroidism and frequent tetany. Vitamin D status should be monitored in patients with intestinal lymphangiectasia.

We report a case of a 59-year-old woman who was diagnosed with gastric and small intestinal anisakiasis, which was successfully treated with endoscopic extraction and Gastrografin therapy. She was admitted to our hospital with epigastric pain and vomiting one day after eating raw fish. She exhibited tenderness in the epigastrium without obvious rebound tenderness or guarding. Computed tomography (CT) demonstrated segmental edema of the intestinal wall with proximal dilatation and a small number of ascites. Because enteric anisakiasis was suspected based on the patient's history of recent raw fish consumption and abdominal CT, we performed gastroscopy and confirmed that nine Anisakis larvae were attached to the gastric mucosa. All of the Anisakis larvae were extracted via endoscopy, and the patient was diagnosed with gastric and enteric anisakiasis. Additionally, in the hospital, we performed ileography twice using Gastrografin, which led to shortened hospital stay. Based on the clinical results of this case, we suggest that Gastrografin therapy is a safe, convenient, and useful method to extract enteric Anisakis larvae.

Coeliac disease is often undiagnosed, early diagnosis and treatment could be relevant to avoid fearful complications as intestinal lymphoma. Our aim is to estimate the risk of intestinal lymphoma in undiagnosed coeliac patients, evaluating the real incidences and applying different theoretical settings of coeliac prevalence. We collected cases of intestinal lymphomas from the Lombardy Cancer Registry and coeliac patients through computerized search of all Pathology Departments; duodenal pathological reports compatible with a Marsh 3 grade were included. The lymphoproliferative risk was calculated for theoretical different settings of coeliac prevalence (from 1:50 to 1:200), relative risks for intestinal lymphomas and compared to the real incidence of the lymphomas in this population. Population consisted in 815,362 inhabitants; during the investigated period of time, 237 intestinal lymphomas and 326 coeliac patients were diagnosed. None of the coeliac patients had lymphoma. In the different scenarios calculated and compared with the real lymphoma incidence the relative risks of undiagnosed celiac disease for gastrointestinal B- and T-cell lymphomas ranges from 1.0 to 2.0 for 1:100 coeliac disease prevalence. Undiagnosed coeliac patients have no increased risk of developing intestinal lymphoma; population screening programmes, aimed at early diagnosis of lymphoma may not be useful in this setting.

Her intestinal granulomatous disease was erroneously diagnosed as Crohn's disease despite the fact that the possibility of tuberculosis was considered. The final diagnosis of tuberculosis was made only when an anti-tumour necrosis factor therapy resulted in further deterioration. The patient was treated with isoniazid, rifampin, pyrazinamide and ethambutol, with slow and steady clinical improvement until complete recovery was achieved. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

The small intestine is the most common location of intestinal graft-versus-host disease (GVHD). EGD with duodenal biopsies yields the highest diagnostic sensitivity, but the jejunum and ileum are not accessible by regular endoscopy. In contrast, wireless capsule endoscopy (WCE) is a noninvasive imaging procedure offering complete evaluation of the small intestine. The objective was to compare the diagnostic value of EGD, including biopsies, with the results of WCE in patients with acute intestinal symptoms who received allogeneic blood stem cell transplantation and to analyze the appearance and distribution of acute intestinal GVHD lesions in these patients. An investigator-blinded, single-center prospective study. Patients with acute intestinal symptoms after allogeneic stem cell transplantation underwent both EGD and WCE within 24 hours. Clinical data were recorded during 2 months of follow-up. Fourteen consecutive patients with clinical symptoms of acute intestinal GVHD were recruited. In 1 patient, the capsule remained in the stomach and was removed endoscopically. In 7 of 13 patients who could be evaluated, acute intestinal GVHD was diagnosed by EGD with biopsies, but 3 of these would have been missed by EGD alone. In all 7 patients with histologically confirmed acute intestinal GVHD, WCE revealed typical signs of GVHD. Lesions were scattered throughout the small intestine, but were most accentuated in the ileum. This study had a small number of patients. WCE, which is less invasive than EGD with biopsies, showed a comparable sensitivity and a high negative predictive value for diagnosing acute intestinal GVHD. It may be helpful to avoid repeated endoscopic procedures in patients who have undergone stem cell transplantation.

Intestinal leiomyositis is a suspected autoimmune disorder affecting the muscularis propria layer of the gastrointestinal tract and is a cause of chronic intestinal pseudo-obstruction in humans and animals. To characterize the clinical presentation, histopathologic features, and outcome of dogs with intestinal leiomyositis in an effort to optimize treatment and prognosis. Six client-owned dogs. Retrospective case series. Medical records were reviewed to describe signalment, clinicopathologic and imaging findings, histopathologic diagnoses, treatment, and outcome. All biopsy specimens were reviewed by a board-certified pathologist. Median age of dogs was 5.4 years (range, 15 months-9 years). Consistent clinical signs included vomiting (6/6), regurgitation (2/6), and small bowel diarrhea (3/6). Median duration of clinical signs before presentation was 13 days (range, 5-150 days). Diagnostic imaging showed marked gastric distension with dilated small intestines in 4/6 dogs. Full-thickness intestinal biopsies were obtained in all dogs by laparotomy. Histopathology of the stomach and intestines disclosed mononuclear inflammation, myofiber degeneration and necrosis, and fibrosis centered within the region of myofiber loss in the intestinal muscularis propria. All dogs received various combinations of immunomodulatory and prokinetic treatment, antimicrobial agents, antiemetics, and IV fluids, but none of the dogs showed a clinically relevant improvement with treatment. Median survival was 19 days after diagnosis (range, 3-270 days). Intestinal leiomyositis is a cause of intestinal pseudo-obstruction and must be diagnosed by full-thickness intestinal biopsy. This disease should be considered in dogs with acute and chronic vomiting, regurgitation, and small bowel diarrhea. Copyright © 2015 The Authors.

Intestinal infections have been claimed to precipitate or aggravate flares of inflammatory bowel disease (IBD). The reported incidence of such infections among IBD patients varies between 9 and 13%, but only a few prospective studies have been conducted. To evaluate the incidence of intestinal infections by enteropathogens in patients with active IBD, their impact on clinical outcome, and to identify associated risk factors. Consecutive patients admitted because of a relapse or suspected onset of IBD were prospectively included. At admittance, stool samples for culture, examination for intestinal parasites, and cytotoxin assay for Clostridium difficile were collected. Baseline clinical characteristics, potential risk factors for gastrointestinal infections, and clinical outcome were recorded. Ninety-nine episodes were included. Six intestinal infections were diagnosed in 6 patients (5 ulcerative colitis, 1 ileocolonic Crohn's disease), Campylobacter jejuni being the most frequent isolated microbe (n = 5). None of the patients with intestinal infection needed surgery, but two of them required second-line therapies. Gastrointestinal infections among IBD patients do not exceed 10% and occur mostly in patients with extensive involvement of the colon. Infection by enteropathogenic bacteria does not appear to be associated with a poorer clinical outcome of the IBD flare. Copyright 2009 S. Karger AG, Basel.

To investigate the influence of proton pump inhibitors (PPIs) exposure on the diagnosis of Helicobacter pylori (H. pylori) gastritis and intestinal metaplasia. Chronic PPI use is associated with masking of H. pylori infection. Patients with H. pylori infection are predisposed to gastric and duodenal ulcers, and long-term infection with this organism has been associated with gastric mucosal atrophy and serious long-term complications, such as gastric lymphoma and adenocarcinoma. Three hundred patients diagnosed with gastritis between January 2008 and April 2010 were included in our study. The computerized medical database of these patients was reviewed retrospectively in order to assess whether the type of gastritis diagnosed (H. pylori vs non-H. pylori gastritis) is influenced by PPI exposure. H. pylori density was graded as low, if corresponding to mild density following the Updated Sydney System, or high, if corresponding to moderate or severe densities in the Updated Sydney System. Patients were equally distributed between males and females with a median age at the time of diagnosis of 50 years old (range: 20-87). The histological types of gastritis were classified as H. pylori gastritis (n = 156, 52%) and non-H. pylori gastritis (n = 144, 48%). All patients with non-H. pylori gastritis had inactive chronic gastritis. Patients with no previous PPI exposure were more likely to be diagnosed with H. pylori gastritis than those with previous PPI exposure (71% vs 34.2%, P < 0.001). Intestinal metaplasia was more likely to be detected in the latter patients (1.4% vs 6.5%, P = 0.023). Multivariate analysis has also demonstrated that in the presence of previous PPI exposure (OR = 0.217, 95%CI: 0.123-0.385), GERD (OR = 0.317, 95%CI: 0.132-0.763, P = 0.01), alcohol intake (OR = 0.396, 95%CI: 0.195-0.804, P = 0.01), the detection of H. pylori was less likely. Chronic use of PPIs may mask H. pylori infections promoting the diagnosis of non-H. pylori gastritis and leads to a significant drop in H. pylori densities and to an increased risk of intestinal metaplasia. The use of PPIs masks H. pylori infection, promotes the diagnosis of non-H. pylori inactive chronic gastritis diagnosis, and increases the incidence of intestinal metaplasia.

The aim of this study was to determine the pattern of histologically-proven gastric cancer in Eastern Libya and explore its association with Helicobacter pylori infection. The registries of the Departments of Histopathology, Faculty of Medicine, Benghazi University and Oncology, Al-Jomhoria Hospital, Benghazi, were reviewed for cases with primary gastrointestinal cancer from January 2000 to December 2002 (sole Histopathology and Oncology Departments in Eastern Libya). Slides of hematoxylin and eosin stain of gastric cancer patients were re-stained to detect H. pylori. The American Joint Committee on Cancer Tumor, Node, Metastasis staging was used for clinical and pathologic staging. Gastric cancer biopsy materials were classified into intestinal or diffuse type according to Lauren criteria. One hundred and fourteen cases of gastric cancer were diagnosed. Tumor stages were: 2 (14%), 3 (21%), 4 (57%) and unknown (8%). Most common site of involvement was the antrum (48%). Diffuse adenocarcinoma occurred in 56 patients (49.1%), intestinal adenocarcinoma in 46 (40.4%) and malignant gastric lymphoma in 12 (10.5%). The overall frequency of H. pylori infection was 63.2% (72/114), more frequent in intestinal adenocarcinoma (71.7%) and malignant lymphoma (66.6%) than diffuse adenocarcinoma (55.3%). The frequency of gastric cancer increased throughout the three years of study. The majority of the patients were diagnosed in locally advanced or metastatic stage. Clearly more efforts need to be given to early detection. We showed a stronger association of H. pylori infection with intestinal type gastric adenocarcinoma and malignant lymphoma than diffuse adenocarcinoma suggesting that H. pylori infection is the most probable causal factor of gastric cancer in this part of Libya.

Bi-allelic germline mutations of one of the DNA mismatch repair genes, so far predominantly found in PMS2, cause constitutional MMR-deficiency syndrome. This rare disorder is characterised by paediatric intestinal cancer and other malignancies. We report the clinical, immunohistochemical and genetic characterisation of four families with bi-allelic germline PMS2 mutations. We present an overview of the published gastrointestinal manifestations of CMMR-D syndrome and propose recommendations for gastro-intestinal screening. The first proband developed a cerebral angiosarcoma at age 2 and two colorectal adenomas at age 7. Genetic testing identified a complete PMS2 gene deletion and a frameshift c.736_741delinsTGTGTGTGAAG (p.Pro246CysfsX3) mutation. In the second family, both the proband and her brother had multiple intestinal adenomas, initially wrongly diagnosed as familial adenomatous polyposis. A splice site c.2174+1G>A, and a missense c.137G>T (p.Ser46Ile) mutation in PMS2 were identified. The third patient was diagnosed with multiple colorectal adenomas at age 11; he developed a high-grade dysplastic colorectal adenocarcinoma at age 21. Two intragenic PMS2 deletions were found. The fourth proband developed a cerebral anaplastic ganglioma at age 9 and a high-grade colerectal dysplastic adenoma at age 10 and carries a homozygous c.2174+1G>A mutation. Tumours of all patients showed microsatellite instability and/or loss of PMS2 expression. Our findings show the association between bi-allelic germline PMS2 mutations and severe childhood-onset gastrointestinal manifestations, and support the notion that patients with early-onset gastrointestinal adenomas and cancer should be investigated for CMMR-D syndrome. We recommend yearly follow-up with colonoscopy from age 6 and simultaneous video-capsule small bowel enteroscopy from age 8. Copyright © 2011 Elsevier Ltd. All rights reserved.

Increasing number of early-onset gastric carcinomas (GCs) and controversial results regarding the differences among young and older patients with this type of cancer are the reasons why correlation of clinicopathological factors with molecular markers is necessary. The aim of our study was to compare the demographic, clinical and immunohistochemical (IHC) aspects in Romanian patients with GC diagnosed below and above 45 years old. In 191 samples provided from patients with GC, the clinicopathological parameters were correlated with a panel of 15 antibodies: E-cadherin, HER-2, VEGF, CD31, CD105, COX-2, maspin, bax, bcl-2, p53, Ki67, MLH-1, MSH-2, mena protein and vimentin. Compared to the conventional cases, GCs diagnosed below 45 years old were more frequently located at the gastroesophageal junction and presented a higher percentage of lymph node metastases. The diffuse type E-cadherin/mena/p53/Ki67/bax-negative cases that displayed nuclear maspin positivity were also more frequently in younger patients. The intestinal type early-onset GCs were the most angiogenic ones, the apoptotic rate being lower than in the intestinal type GCs of the aged. Compared to the conventional cases, in the early-onset GCs the nuclear maspin-mediated antiproliferative activity is more intense in diffuse type while the mena-dependent tumor cell proliferation is more characteristic for intestinal type GCs. © 2014 APMIS.

To determine the occurrence of intestinal and extraintestinal cancers in the 1993-2009 prospective European Collaborative Inflammatory Bowel Disease (EC-IBD) Study Group cohort. A physician per patient form was completed for 681 inflammatory bowel disease patients (445UC/236CD) from 9 centers (7 countries) derived from the original EC-IBD cohort. For the 15-year follow up period, rates of detection of intestinal and extraintestinal cancers were computed. Patient follow-up time was fifteen years. In total 62/681 patients (9.1%) [41 with ulcerative colitis/21 with Crohn's disease, 36 males/26 females] were diagnosed with sixty-six cancers (four patients with double cancers). Colorectal cancer was diagnosed in 9/681 patients [1.3%] (1 Crohn's disease and 8 ulcerative colitis). The remaining 53 cancers were extraintestinal. There was a higher prevalence of intestinal cancer in the Northern centers compared to Southern centers [p=NS]. Southern centers had more cases of extraintestinal cancer compared to Northern centers [p=NS]. The frequency of all observed types of cancers in Northern and in Southern centers did not differ compared to the expected one in the background population. In the fifteen-year follow up of the EC-IBD Study Group cohort the prevalence of cancer was 9.1% with most patients having a single neoplasm and an extraintestinal neoplasm. In Northern centers there were more intestinal cancers while in Southern centers there were more extraintestinal cancers compared to Northern centers. In this IBD cohort the frequency of observed cancers was not different from that expected in the background population. Copyright © 2011 European Crohn's and Colitis Organisation.

Primary volvulus of the small intestine associated with chylous ascites is very rare, with only four reported cases. In this paper, we report a new case of primary volvulus associated with chylous ascites. The patient was a 70-year-old man. After experiencing bloating and abdominal pain for several hours, he called an ambulance and underwent an emergency examination at our hospital. Abdominal distension, pressure pain, and rebound tenderness were observed throughout his entire abdomen. The patient had a history of hypertension for which he was receiving oral treatment. Abdominal contrast-enhanced computed tomography (CT) revealed an edematous change in the intestinal membrane and volvulus of the small intestine. As findings suggestive of ischemia were observed in part of the intestines, emergency surgery was performed on the day of admission. Open surgery revealed approximately 500 mL of chylous ascites in the abdominal cavity. The small intestine had twisted 180° in a counter-clockwise direction at the root of the superior mesenteric artery, and the mesentery appeared milky white with edematous changes extending 75 to 240 cm from the ligament of Treitz. There was no evidence of intestinal necrosis; therefore intestinal resection was not performed. The volvulus of the small intestine was corrected. Moreover, because there was no other underlying disease observed, surgery was completed. The ascites collected during surgery revealed high levels of triglycerides at 332 mg/dL, and chylous ascites was diagnosed. An abdominal CT performed on the third day after surgery showed an improvement in intestinal edema, and primary volvulus of the small intestine associated with chylous ascites was diagnosed. Postoperative progress was good, and the patient was discharged on hospital day 10.

Intestinal hyperpermeability is a causal factor for the development of alcoholic endotoxemia and steatohepatitis. However, the mechanisms governing this link remain unknown. The purpose of this study was to determine whether toll-like receptor 4 (TLR4) is involved in ethanol's deleterious effects on the intestinal barrier. Caco-2 cells were incubated in vitro with 1-10% ethanol. The results indicated that ethanol had a dose-dependent effect in increasing TLR4 expression and intercellular permeability. Then the effects of TLR4 on protein kinase C (PKC) and the intercellular junction protein occludin were assessed with and without pretreatment with a TLR4 inhibitor. The results indicated that TLR4 increased nonspecific PKC activity and reduced the expression of phosphorylated occludin in the membrane, which increased intercellular permeability. These effects were prevented by pretreatment with TLR4 mAb. Wild-type C57BL/6 mice were fed an ethanol or isocaloric liquid diet for 6 weeks. Hepatitis was diagnosed by the presence of an associated elevated blood endotoxin level. Chronic ethanol treatment significantly elevated blood endotoxin levels, intestinal permeability, and the expression of TLR4 in the ileum and colon. Moreover, ethanol exposure reduced the distribution of phosphorylated occludin in the intestinal epithelium because of PKC activation. In conclusion, chronic ethanol exposure induces a high response of TLR4 to lipopolysaccharide (LPS), and TLR4 increases intestinal permeability through down-regulation of phosphorylated occludin expression in the intestinal epithelial barrier, accompanied by membrane PKC hyperactivity.

Strongylus vulgaris is re-emerging in horses kept under surveillance-based parasite control regimens. Information on nonstrangulating intestinal infarction associated with S. vulgaris is needed to improve recognition of the condition. To describe the typical clinical presentation, laboratory findings, gross pathology, treatment and outcome of horses with nonstrangulating intestinal infarction. Retrospective case series. Nonstrangluating intestinal infarction was diagnosed in 30 horses with a localised intestinal infarction with concurrent signs of S. vulgaris migration and no signs of intestinal strangulation or enterocolitis. Data were obtained from medical records in the period 2008-2016. Long-term follow-up information was obtained by telephonic interviews. Levels of S. vulgaris-specific antibodies were retrospectively assessed. Associations between nonstrangulating intestinal infarction and selected variables were evaluated using Fisher's exact and Mann-Whitney U tests. The most consistent findings at admission were mild colic of >24 h duration without signs of shock or strangulated intestine, increased peritoneal fluid WBC (>5 × 10 9 /L), increased serum amyloid A (SAA) concentration and a positive S. vulgaris-specific antibody titre. Medical treatment was attempted in nine horses with none surviving. Exploratory laparotomy was performed in 21 horses. Eleven horses were subjected to euthanasia intraoperatively due to the presumed poor prognosis. Of the nine horses, three (33%) undergoing intestinal resection survived to discharge. The surviving horses were alive and returned to athletic function for at least 2 years following discharge. Only nine of the 30 horses underwent resection of the infarcted intestine, and the prognosis for surgical intervention in nonstrangulating intestinal infarction is, therefore, difficult to estimate. In areas where S. vulgaris is prevalent, nonstrangulating intestinal infarction should be considered as a differential diagnosis in horses presenting with mild colic and peritonitis. Survival of nonstrangulating intestinal infarction is possible in cases where surgical intervention with resection of the infarcted intestine is feasible.

Blunt abdominal trauma can damage the intestinal vasculature and may occasionally lead to delayed intestinal perforation, associated with a combined rate of morbidity and mortality of 25%. The diagnosis of such complications is hindered by sedation in critical patients, however, and morbimortality in this population is therefore higher. We report the case of a man with multiple injuries admitted to the intensive care unit, where delayed perforations of the sigmoid colon and cecum were diagnosed. The management of blunt abdominal trauma is reviewed and the possible causes, diagnostic approaches, and treatment options for colon injuries are discussed.

Four dogs were examined because of vomiting of 7 to 48 hours' duration. Gas-distended segments of intestine were identified radiographically in all dogs, but the affected portion of the intestinal tract could not always be identified as the colon. Volvulus of the colon was diagnosed during surgery in all 4 dogs. Gastrocolopexy was performed following derotation of the colon in 3 of the dogs. In 1 dog, a colectomy and an ileorectal anastomosis were performed. All 4 dogs survived. Volvulus of the colon should be considered as a cause of vomiting of short duration in dogs for which there is radiographic evidence of intestinal dilatation.

Primary intestinal lymphangiectasia with generalized warts

2015-01-01

Primary intestinal lymphangiectasia (PIL) is a rare protein-losing enteropathy with lymphatic leakage into the small intestine. Dilated lymphatics in the small intestinal wall and mesentery are observed in this disease. Laboratory tests of PIL patients revealed hypoalbuminemia, lymphocytopenia, hypogammaglobulinemia and increased stool α-1 antitrypsin clearance. Cell-mediated immunodeficiency is also present in PIL patients because of loss of lymphocytes. As a result, the patients are vulnerable to chronic viral infection and lymphoma. However, cases of PIL with chronic viral infection, such as human papilloma virus-induced warts, are rarely reported. We report a rare case of PIL with generalized warts in a 36-year-old male patient. PIL was diagnosed by capsule endoscopy and colonoscopic biopsy with histological tissue confirmation. Generalized warts were observed on the head, chest, abdomen, back, anus, and upper and lower extremities, including the hands and feet of the patient. PMID:26217101

Enterobiasis is one of the most common human parasitic infections. It is considered an intestinal parasite, but cases of extra-intestinal affections exist, notably infections of the female genital tract. Enterobius vermicularis (EV) eggs (or ova) have been found in the cervical smears of two patients in our institute during the last 16 years. No gynaecological or gastrointestinal symptoms were reported, and there was no known intestinal infection in these two cases. A review of the available literature revealed rare cases of vaginal enterobiasis, with a wide range of clinical presentations, many patients being asymptomatic. The diagnosis may sometimes be difficult, mainly because of the lack of clinical suspicion. However, cytological identification of EV in cervico-vaginal smears is important, especially when considering the risk of ascending infections of the genital tract associated with severe complications. © 2017 Wiley Periodicals, Inc.

Whole Exome Sequencing Identifies de Novo Mutations in GATA6 Associated with Congenital Diaphragmatic Hernia

Background Congenital diaphragmatic hernia (CDH) is a common birth defect affecting 1 in 3,000 births. It is characterized by herniation of abdominal viscera through an incompletely formed diaphragm. Although chromosomal anomalies and mutations in several genes have been implicated, the cause for most patients is unknown. Methods We used whole exome sequencing in two families with CDH and congenital heart disease, and identified mutations in GATA6 in both. Results In the first family, we identified a de novo missense mutation (c.1366C>T, p.R456C) in a sporadic CDH patient with tetralogy of Fallot. In the second, a nonsense mutation (c.712G>T, p.G238*) was identified in two siblings with CDH and a large ventricular septal defect. The G238* mutation was inherited from their mother, who was clinically affected with congenital absence of the pericardium, patent ductus arteriosus, and intestinal malrotation. Deep sequencing of blood and saliva derived DNA from the mother suggested somatic mosaicism as an explanation for her milder phenotype, with only approximately 15% mutant alleles. To determine the frequency of GATA6 mutations in CDH, we sequenced the gene in 378 patients with CDH. We identified one additional de novo mutation (c.1071delG, p.V358Cfs34*). Conclusions Mutations in GATA6 have been previously associated with pancreatic agenesis and congenital heart disease. We conclude that, in addition to the heart and the pancreas, GATA6 is involved in development of two additional organs, the diaphragm and the pericardium. In addition we have shown that de novo mutations can contribute to the development of CDH, a common birth defect. PMID:24385578

Postnatally diagnosed congenital diaphragmatic hernias (CDH) are rare and have a better prognosis than those diagnosed prenatally. Postnatal symptoms can be respiratory, digestive, or mixed. Gastric volvulus can reveal CDH. Symptoms are pain, abdominal distension, and/or vomiting. Upper gastrointestinal barium X-ray radiography provides the diagnosis. Prognosis is related to early surgical management in complicated forms with intestinal occlusion or sub-occlusion. We report on an infant who presented with vomiting, which revealed gastric volvulus associated with a CDH. Progression was favorable after surgical treatment. Copyright © 2017 Elsevier Masson SAS.

Type 1 neurofibromatosis associates various abdominal tumors as gastrointestinal stromal tumors, duodenal or pancreatic carcinoid, and adrenal tumors like pheochromocytoma. We present the immunohistochemistry report in two cases with different profile regarding the evolution. One case is a 7th decade women diagnosed with unilateral pheochromocytoma and GISTs, with a good prognosis after surgery. The other case is a 41-year-old male diagnosed with duodenal metastatic somatostatinoma after an intestinal occlusive syndrome and later the hormonal profile leaded to the diagnosis of pheochromocytoma. The patient had a fulminate evolution within six months from diagnosis.

Meckel's diverticulum incarcerated in a transmesocolic internal hernia

2014-01-01

Intestinal obstruction is a common complication associated with Meckel’s diverticulum in adults. The diverticulum itself or its fibrous band can lead to an intestinal volvulus, intussusceptions, or closed-loop obstructions, which require surgery. The incarceration of Meckel’s diverticulum in either inguinal or femoral hernia sacs (Littre’s hernia) is another, less common, etiology underlying intestinal obstruction. This case report describes a 45-year-old man who had an obstruction associated with a Meckel’s diverticulum that passed through a congenital defect in the mesocolon into the right subphrenic space. The patient, who had not undergone abdominal surgery previously, came to the emergency room with acute onset of intermittent epigastric pain and abdominal distention. Computed tomography images showed the presence of a segment of the small bowel and a diverticulum in the right subphrenic space and paracolic gutter. The twisted mesentery and the dilated loops of the proximal small bowel were indicative of an intestinal volvulus and obstruction. Meckel’s diverticulum complicated by a transmesocolic internal hernia was diagnosed, and this condition was confirmed during emergency surgery. The patient’s postoperative recovery was uneventful. This case report highlights another presentation of Meckel’s diverticulum, that is, in combination with a transmesocolic internal hernia. This etiology may lead to an intestinal volvulus and necessitate early surgery. PMID:25309093

In this cross-sectional study, the associations between helminth infections and ABO blood group, anaemia and undernutrition were investigated in 480 febrile outpatients who visited Dore Bafeno Health Centre, southern Ethiopia, in December 2010. Stool specimens were processed using the Kato-Katz method and examined for intestinal helminth infections. Haemoglobin level was measured using a HemoCue machine and blood group was determined using an antisera haemagglutination test. Nutritional status of the study participants was assessed using height and weight measurements. Among the study participants, 50.2% were infected with intestinal helminths. Ascaris lumbricoides (32.7%), Trichuris trichiura (12.7%), Schistosoma mansoni (11.9%) and hookworm (11.0%) were the most frequently diagnosed helminths. The odds of infection and mean eggs per gram of different intestinal helminth species were comparable between the various blood groups. Among individuals who were infected with intestinal helminth(s), the mean haemoglobin level was significantly lower in individuals harbouring three or more helminth species and blood type AB compared to cases with double or single helminth infection and blood type O, respectively. The odds of being underweight was significantly higher in A. lumbricoides and T. trichiura infected individuals of age ≤ 5 and ≥ 20 years, respectively, when compared to individuals of the matching age group without intestinal helminths. In conclusion, infection with multiple intestinal helminths was associated with lower haemoglobin level, which was more severe in individuals with blood type AB. Future studies should focus on mechanisms by which blood group AB exacerbates the helminth-related reduction in mean haemoglobin level.

Sirenomelia is an uncommon congenital malformation of unknown etiology characterized by all degrees of severity in merning, malrotation, and dysgenesis of the lower limbs, combining as it does malformation with several anomalies of the external and internal organs, specially of the urogenital and gastrointestinal systems and other lumbosacral vertebral abnormalities; the severity of the associated malformations are not compatible with life. A genetic mechanism leading to sirenomelia is unlikely, due to the absence of the familial cases.

AIM: To investigate the influence of proton pump inhibitors (PPIs) exposure on the diagnosis of Helicobacter pylori (H. pylori) gastritis and intestinal metaplasia. METHODS: Chronic PPI use is associated with masking of H. pylori infection. Patients with H. pylori infection are predisposed to gastric and duodenal ulcers, and long-term infection with this organism has been associated with gastric mucosal atrophy and serious long-term complications, such as gastric lymphoma and adenocarcinoma. Three hundred patients diagnosed with gastritis between January 2008 and April 2010 were included in our study. The computerized medical database of these patients was reviewed retrospectively in order to assess whether the type of gastritis diagnosed (H. pylori vs non-H. pylori gastritis) is influenced by PPI exposure. H. pylori density was graded as low, if corresponding to mild density following the Updated Sydney System, or high, if corresponding to moderate or severe densities in the Updated Sydney System. RESULTS: Patients were equally distributed between males and females with a median age at the time of diagnosis of 50 years old (range: 20-87). The histological types of gastritis were classified as H. pylori gastritis (n = 156, 52%) and non-H. pylori gastritis (n = 144, 48%). All patients with non-H. pylori gastritis had inactive chronic gastritis. Patients with no previous PPI exposure were more likely to be diagnosed with H. pylori gastritis than those with previous PPI exposure (71% vs 34.2%, P < 0.001). Intestinal metaplasia was more likely to be detected in the latter patients (1.4% vs 6.5%, P = 0.023). Multivariate analysis has also demonstrated that in the presence of previous PPI exposure (OR = 0.217, 95%CI: 0.123-0.385), GERD (OR = 0.317, 95%CI: 0.132-0.763, P = 0.01), alcohol intake (OR = 0.396, 95%CI: 0.195-0.804, P = 0.01), the detection of H. pylori was less likely. Chronic use of PPIs may mask H. pylori infections promoting the diagnosis of non-H. pylori gastritis and leads to a significant drop in H. pylori densities and to an increased risk of intestinal metaplasia. CONCLUSION: The use of PPIs masks H. pylori infection, promotes the diagnosis of non-H. pylori inactive chronic gastritis diagnosis, and increases the incidence of intestinal metaplasia.

Prevalence of intestinal protozoa infection among school-aged children on Pemba Island, Tanzania, and effect of single-dose albendazole, nitazoxanide and albendazole-nitazoxanide

PubMed Central

2013-01-01

Background Pathogenic intestinal protozoa infections are common in school-aged children in the developing world and they are frequently associated with malabsorption syndromes and gastrointestinal morbidity. Since diagnosis of these parasites is difficult, prevalence data on intestinal protozoa is scarce. Methods We collected two stool samples from school-aged children on Pemba Island, Tanzania, as part of a randomized controlled trial before and 3 weeks after treatment with (i) single-dose albendazole (400 mg); (ii) single-dose nitazoxanide (1,000 mg); (iii) nitazoxanide-albendazole combination (1,000 mg–400 mg), with each drug given separately on two consecutive days; and (iv) placebo. Formalin-fixed stool samples were examined for the presence of intestinal protozoa using an ether-concentration method to determine the prevalence and estimate cure rates (CRs). Results Almost half (48.7%) of the children were diagnosed with at least one of the (potentially) pathogenic protozoa Giardia intestinalis, Entamoeba histolytica/E. dispar and Blastocystis hominis. Observed CRs were high for all treatment arms, including placebo. Nitazoxanide showed a significant effect compared to placebo against the non-pathogenic protozoon Entamoeba coli. Conclusions Intestinal protozoa infections might be of substantial health relevance even in settings where they are not considered as a health problem. Examination of a single stool sample with the ether-concentration method lacks sensitivity for the diagnosis of intestinal protozoa, and hence, care is indicated when interpreting prevalence estimates and treatment effects.

The effects of helminth co-infection on malaria in humans remain uncertain. This study aimed to evaluate the nature of association of intestinal helminths with prevalence and clinical outcomes of Plasmodium infection. A cross-sectional study involving 1,065 malaria suspected febrile patients was conducted at Dore Bafeno Health Center, Southern Ethiopia, from December 2010 to February 2011. Plasmodium and intestinal helminth infections were diagnosed using Giemsa-stained blood films and Kato-Katz technique, respectively. Haemoglobin level was determined using a haemocue machine. Among 1,065 malaria suspected febrile patients, 28.8% were positive for Plasmodium parasites (P. falciparum =13.0%, P. vivax =14.5%, P. falciparum and P. vivax =1.3%). Among 702 patients who provided stool samples, 53.8%, 31.6% and 19.4% were infected with intestinal helminths, Plasmodium alone and with both Plasmodium and intestinal helminths, respectively. The prevalence of infections with Ascaris lumbricoides (A. lumbricoides), Trichuris trichiura (T. trichiura), Schistosoma mansoni (S. mansoni) and hookworm (9.8%) were 35.9%, 15.8%, 11.7% and 9.8%, respectively. Out of the 222 (31.6%) Plasmodium infected cases, 9 (4.1%) had severe malaria. P. falciparum infection was more common in febrile patients infected with A. lumbricoides alone (21.3%), T. trichiura alone (23.1%) and S. mansoni alone (23.1%) compared to those without intestinal helminth infections (9.3%) (p<0.001 for all). Prevalence of non-severe malaria was significantly higher in individuals infected with intestinal helminths than in those who were not infected with intestinal helminths (adjusted OR=1.58, 95% CI=1.13-2.22). The chance of developing non-severe P. falciparum malaria were 2.6, 2.8 and 3.3 times higher in individuals infected with A. lumbricoides alone, T. trichiura alone and S. mansoni alone, respectively, compared to intestinal helminth-free individuals (p<0.05 for all). The odds ratio for being infected with non-severe P. falciparum increased with the number of intestinal helminth species (p<0.001). Mean Plasmodium density among intestinal helminth infected individuals was significantly increased with the number of intestinal helminths species (p=0.027). Individuals who were co-infected with different species of intestinal helminths and Plasmodium showed lower mean haemoglobin concentration than individuals who were infected only with Plasmodium. Infections with A. lumbricoides, T. trichiura and S. mansoni were positively associated with P. falciparum infection. However, further studies are required to investigate how these helminths could contribute to increased prevalence of P. falciparum infection.

Microvillous inclusion disease is a rare autosomal recessive condition, characterized by severe secretory diarrhea that produces a permanent intestinal failure and dependency on parenteral nutrition. It usually begins in the neonatal period, and the only treatment at present is intestinal transplantation. A retrospective review was conducted on 6 patients (three males and three females) diagnosed with microvillous inclusion disease between 1998 and 2013. All debuted in the first month of life, with a median age of three days (range, 3-30 days), and had secretory diarrhea dependent on parenteral nutrition, with fasting fecal volume of 150-200ml/kg/day. Light microscopy of duodenal biopsy samples showed varying degrees of villous atrophy without cryptic hyperplasia, accumulation of PAS positive material in the cytoplasm of enterocytes brush border, and anti-CD10 immunostaining was suggestive of intracytoplasmic inclusions. Diagnostic confirmation was performed with electron microscopy. Two of them had a genetic study, and showed mutations in MYO5B gene. Three died and three are alive; two of them with an intestinal transplantation and the third waiting for a multivisceral transplantation. Copyright © 2014 Asociación Española de Pediatría.

Gallstones and kidney stones are known complications of inflammatory bowel diseases (IBD). Risk factors have been insufficiently studied and explanatory studies date back up to 30 years. It remains unclear, whether improved treatment options also influenced risk factors for these complications. Identifying risk factors for gallstones and kidney stones in IBD patients. Using data from the Swiss Inflammatory Bowel Disease Cohort Study we assessed associations of diseases characteristics with gallstones and kidney stones in univariate and multivariate logistic regression analyses. Out of 2323 IBD patients, 104 (7.8%) Crohn's disease (CD) and 38 (3.8%) ulcerative colitis (UC) patients were diagnosed with gallstones. Significant risk factors for gallstones were diagnosis of CD, age at diagnosis, disease activity and duration, NSAID intake, extra-intestinal manifestations and intestinal surgery. Kidney stones were described in 61 (4.6%) CD and 30 (3.0%) UC patients. Male gender, disease activity, intestinal surgery, NSAID usage and reduced physical activity were significant risk factors. Hospitalization was associated with gallstones and kidney stones. The presence of gallstones increased the risk for kidney stones (OR 4.87, p<0.001). The diagnosis of CD, intestinal surgery, prolonged NSAID use, disease activity and duration and bowel stenosis were significantly associated with cholecystonephrolithiasis in IBD.

Patients with celiac disease (CD) often have articular complaints, and small prior studies suggest an association with Ehlers-Danlos syndrome (EDS)/joint hypermobility syndrome (JHS). This study examines the risks of EDS/JHS in patients with CD. This cohort study compared all individuals in Sweden diagnosed with CD based on small intestinal biopsy between 1969-2008 (n=28,631) to 139,832 matched reference individuals, and to a second reference group undergoing biopsy without having CD (n=16,104). Rates of EDS/JHS were determined based on diagnostic codes in the Swedish Patient Register. Hazard ratios (HRs) for EDS/JHS were estimated through Cox regression. There are 45 and 148 cases of EDS/JHS in patients with CD and reference individuals, respectively. This corresponds to a 49% increased risk of EDS/JHS in CD (95%CI=1.07-2.07). The HR for EDS was 2.43 (95%CI=1.20-4.91) and for JHS 1.34 (95%CI=0.93-1.95). Compared to reference individuals undergoing intestinal biopsy, CD was not a risk factor for EDS/JHS. A stronger association was seen in patients initially diagnosed with EDS/JHS and subsequently diagnosed with CD (odds ratio=2.29; 95%CI=1.21-4.34). Individuals with CD have higher risk of EDS/JHS than the general population, which may be due to surveillance bias or factors intrinsic to celiac development.

2017-01-01

A 12-year-old, 3.6-kg, spayed female domestic shorthaired cat had a 2-month history of anorexia and weight loss. Abdominal ultrasonography and computed tomography revealed an exophytic mass originating from the jejunum with very poor central and poor peripheral contrast enhancement. On day 14, surgical resection of the jejunum and mass with 5-cm margins and an end-to-end anastomosis were performed. Histopathological examination revealed the mass was a transmural, invasive cancer showing exophytic growth and originating from the small intestinal muscle layer. Immunohistochemical analysis of tumor cells revealed diffuse positivity for KIT protein and negativity for desmin and S-100. The mass was diagnosed as a gastrointestinal stromal tumor (GIST). Ultrasonographic findings indicated the tumor probably metastasized to the liver and omentum, as seen in humans and dogs. The owner rejected further treatment at the last visit on day 192. To our knowledge, this is the first report of intestinal tumor and metastasis in feline GIST and its imaging features. PMID:28163271

Examine effects of hospital transfer into a quaternary care center on surgical outcomes of intestinal atresia. Children <1 yo principally diagnosed with intestinal atresia were identified using the Kids' Inpatient Database (2012). Exposure variable was patient transfer status. Outcomes measured were inpatient mortality, hospital length of stay (LOS) and discharge status. Linearized standard errors, design-based F tests, and multivariable logistic regression were performed. 1672 weighted discharges represented a national cohort. The highest income group and those with private insurance had significantly lower odds of transfer (OR:0.53 and 0.74, p < 0.05). Rural patients had significantly higher transfer rates (OR: 2.73, p < 0.05). Multivariate analysis revealed no difference in mortality (OR:0.71, p = 0.464) or non-home discharge (OR: 0.79, p = 0.166), but showed prolonged LOS (OR:1.79, p < 0.05) amongst transferred patients. Significant differences in hospital LOS and treatment access reveal a potential healthcare gap. Post-acute care resources should be improved for transferred patients. Copyright © 2016 Elsevier Inc.

A 63-year-old man, who had undergone total gastrectomy and Roux-en-Y reconstruction for gastric cancer 10 years previously, was admitted to our hospital with complaints of abdominal pain, palpable abdominal tumor, and hematemesis. On admission, the abdominal tenderness was improving and no abdominal tumor was palpable. Mild inflammatory changes and anemia were noted on blood examination. Abdominal computed tomography revealed a tumor with a layered structure in the left abdomen. The patient was diagnosed with intestinal obstruction secondary to intussusception, and surgery was performed. Retrograde intussusception was found at the site of the Y anastomosis. We conducted manual reduction using the Hutchinson procedure. The intestinal color after the reduction was good, and no intestinal resection was required. Postoperative recovery was uneventful, and the patient was discharged 12 days after surgery. Reports of jejunal intussusception after total gastrectomy with Roux-en-Y reconstruction are relatively rare. Here, we report a case of jejunal intussusception after total gastrectomy with Roux-en-Y reconstruction.

Enteropathy-associated T-cell lymphomas (EATL) are rare and generally aggressive types of peripheral T-cell lymphomas. Rare cases of primary, small intestinal CD4+ T-cell lymphomas with indolent behavior have been described, but are not well characterized. We describe morphologic, phenotypic, genomic and clinical features of 3 cases of indolent primary small intestinal CD4+ T-cell lymphomas. All patients presented with diarrhea and weight loss and were diagnosed with celiac disease refractory to a gluten free diet at referring institutions. Small intestinal biopsies showed crypt hyperplasia, villous atrophy and a dense lamina propria infiltrate of small-sized CD4+ T-cells often with CD7 downregulation or loss. Gastric and colonic involvement was also detected (n = 2 each). Persistent, clonal TCRβ gene rearrangement products were detected at multiple sites. SNP array analysis showed relative genomic stability, early in disease course, and non-recurrent genetic abnormalities, but complex changes were seen at disease transformation (n = 1). Two patients are alive with persistent disease (4.6 and 2.5 years post-diagnosis), despite immunomodulatory therapy; one died due to bowel perforation related to large cell transformation 11 years post-diagnosis. Unique pathobiologic features warrant designation of indolent small intestinal CD4+ T-cell lymphoma as a distinct entity, greater awareness of which would avoid misdiagnosis as EATL or an inflammatory disorder, especially celiac disease.

[Management of mesenteric ischemia in the era of intestinal stroke centers: The gut and lifesaving strategy].

PubMed

Nuzzo, A; Corcos, O

2017-09-01

Mesenteric ischemia is a gut and life-threatening, medical and surgical, digestive and vascular emergency. Mesenteric ischemia is the result of an arterial or venous occlusion, a vasospasm secondary to low-flow states in intensive care patients, aortic clamping during vascular surgery or intestinal transplantation. Progression towards mesenteric infarction and its complications is unpredictable and correlates with high rates of mortality or a high risk of short bowel syndrome in case of survival. Thus, mesenteric ischemia should be diagnosed and treated at an early stage, when gut injury is still reversible. Diagnostic workup lacks sensitive and specific clinical and biological marker. Consequently, diagnosis and effective therapy can be achieved by a high clinical suspicion and a specific multimodal management: the gut and lifesaving strategy. Based on the model of ischemic stroke centers, the need for a multidisciplinary and expert 24/24 emergency care has led, in 2016, to the inauguration of the first Intestinal Stroke Center (Structure d'urgences vasculaires intestinales [SURVI]) in France. This review highlights the pathophysiological features of chronic and acute mesenteric ischemia, as well as the diagnosis workup and the therapeutic management developed in this Intestinal Stroke Center.

Intestinal coccidian parasites are intracellular protozoa most frequently transmitted during food-borne and water-borne infections. This group of parasites is responsible for acute diarrhoeal illnesses especially among immunocompromised patients. However, they are more frequently detected in immunocompetent individuals including travellers, and they should also be considered as important etiologic factors of travellers' diarrhoea. We examined 221 immunocompetent patients hospitalized due to acute or chronic diarrhoea and other gastrointestinal symptoms after returning from international journeys to hot climates. A basic microscopical examination and acid - fast staining of stool samples was performed. Each patient was also a part of the epidemiological investigation to define potential risk factors of tropical gastrointestinal infections. Intestinal coccidiosis was confirmed in 12 out of 221 successively hospitalized patients (5.4%). The most common coccidian parasite was Cryptosporidium spp., detected in nine Polish travellers (4.1%). Cyclospora spp. was diagnosed in three cases (1.4%), including two mixed infections with Cryptosporidium spp., and Cystoisospora spp. in two other cases (0.9%). The study has revealed that intestinal coccidian parasites are a significant threat to immunocompetent travellers and should be always considered in the differential diagnosis of gastrointestinal disorders. Therefore, it is necessary to perform specialized diagnostic methods for the detection of Cryptosporidium spp., Cystoisospora spp., and Cyclospora spp. oocysts in reference parasitology laboratories. Clinical observations demonstrated simultaneously an insufficient level of knowledge in Polish tourists concerning the main risk factors of intestinal parasitic diseases during international travels, particularly to developing countries with lower economic and sanitary conditions.

Abstract For over a decade, spontaneous intestinal neoplasia has been observed in zebrafish (Danio rerio) submitted to the ZIRC (Zebrafish International Resource Center) diagnostic service. In addition, zebrafish displayed preneoplastic intestinal changes including hyperplasia, dysplasia, and enteritis. A total of 195 zebrafish, representing 2% of the total fish submitted to the service, were diagnosed with these lesions. Neoplastic changes were classified either as adenocarcinoma or small cell carcinoma, with a few exceptions (carcinoma not otherwise specified, tubular adenoma, and tubulovillous adenoma). Tumor prevalence appeared similarly distributed between sexes and generally occurred in zebrafish greater than 1 year of age, although neoplastic changes were observed in fish 6 months of age. Eleven lines displayed these preneoplastic and neoplastic changes, including wild-types and mutants. Affected zebrafish originated from 18 facilities, but the majority of fish were from a single zebrafish research facility (hereafter referred to as the primary facility) that has submitted numerous samples to the ZIRC diagnostic service. Zebrafish from the primary facility submitted as normal sentinel fish demonstrate that these lesions are most often subclinical. Fish fed the diet from the primary facility and held at another location did not develop intestinal lesions, indicating that diet is not the etiologic agent. PMID:23544991

Metabolism and Fitness of Urinary Tract Pathogens.

PubMed

Alteri, Christopher J; Mobley, Harry L T

2015-06-01

Among common infections, urinary tract infections (UTI) are the most frequently diagnosed urologic disease. The majority of UTIs are caused by uropathogenic Escherichia coli. The primary niche occupied by E. coli is the lower intestinal tract of mammals, where it resides as a beneficial component of the commensal microbiota. Although it is well-known that E. coli resides in the human intestine as a harmless commensal, specific strains or pathotypes have the potential to cause a wide spectrum of intestinal and diarrheal diseases. In contrast, extraintestinal E. coli pathotypes reside harmlessly in the human intestinal microenvironment but, upon access to sites outside of the intestine, become a major cause of human morbidity and mortality as a consequence of invasive UTI (pyelonephritis, bacteremia, or septicemia). Thus, extraintestinal pathotypes like uropathogenic E. coli (UPEC) possess an enhanced ability to cause infection outside of the intestinal tract and colonize the urinary tract, the bloodstream, or cerebrospinal fluid of human hosts. Due to the requirement for these E. coli to replicate in and colonize both the intestine and extraintestinal environments, we posit that physiology and metabolism of UPEC strains is paramount. Here we discuss that the ability to survive in the urinary tract depends as much on bacterial physiology and metabolism as it does on the well-considered virulence determinants.

Crohn disease of the vulva is a rare disease that is difficult to diagnose. There are limited reports describing treatment of this condition. To describe the diagnosis and treatment of a 16-year-old girl with Crohn disease of the vulva, without onset of intestinal symptoms. Crohn disease was diagnosed by histopathology. The patient was treated with corticosteroids and followed for 1 year. After the final diagnosis, cutaneous lesions responded rapidly to corticosteroid treatment, which was gradually stopped after 6 months. The disease was well controlled at the 1-year follow-up. Crohn disease of the vulva can develop alone without the onset of intestinal symptoms. Diagnosis relies on special pathologic findings. Corticosteroid treatment is effective for this condition. © 2014 Canadian Dermatology Association.

Lymphangiomas are congenital malformations of the lymphatic system that account for about 5% of all benign tumors in infants and children.1 The most common sites are the neck and axilla, which account for 95% of cases.2 Abdominal cystic lymphangiomas are quite rare, and can arise from either the retroperitoneum, gastrointestinal tract, or the mesentery of the abdominal viscera.3 The presenting symptoms are painless abdominal distension, a palpable mass, or secondary complications in the abdomen such as intestinal obstruction, volvulus, intestinal infarction, or bleeding.4 Typically diagnosed during childhood, these tumors prompt surgical intervention. We describe an atypical case of an abdominal cystic lymphangioma, which did not manifest until adulthood, with atypical symptoms of a rapidly expanding and symptomatic mass. PMID:21139927

PCR analysis is superior to histology for diagnosis of Whipple's disease mimicking seronegative rheumatic diseases.

Lehmann, P; Ehrenstein, B; Hartung, W; Dragonas, C; Reischl, U; Fleck, M

2017-03-01

The diagnosis of Whipple's disease (WD) is commonly confirmed by histology demonstrating Periodic Acid Schiff (PAS)-positive macrophages in the duodenal mucosa. Analysis of intestinal tissue or other specimens using polymerase chain reaction (PCR) is a more sensitive method. However, the relevance of positive PCR findings is still controversial. Therefore, we evaluated the relevance of histology and PCR findings to establishing the diagnosis of WD in a series of WD patients initially presenting with suspected rheumatic diseases. Between 2006 and 2014, 20 patients with seronegative rheumatic diseases tested positive for Tropheryma whipplei (Tw) by PCR and/or histology and were enrolled in a retrospective analysis of the diagnostic value of both procedures. Seven of the 20 cases (35%) were diagnosed with 'classic' WD as indicated by PAS-positive macrophages. In the remaining 13 patients, the presence of Tw was detected by intestinal (n = 10) or synovial PCR analysis (n = 3). Two of the 20 patients (10%) with evidence of Tw did not respond to antibiotic therapy. They were not considered to suffer from WD. Therefore, relying only on histological findings of intestinal biopsies would have missed 11 (61%) of the 18 patients with WD in our cohort. In comparison, PCR of intestinal biopsies detected Tw-DNA in 14 (93%) of the 15 WD patients evaluated. Patients with a positive histology did not differ from PCR-positive patients with regard to sex, age, or duration of disease, but more often presented with gastrointestinal symptoms. A substantial number of WD patients present without typical intestinal histology findings. Additional PCR analysis of intestinal tissue or synovial fluid increased the sensitivity of the diagnostic evaluation and should be considered particularly in patients presenting with atypical seronegative rheumatic diseases and a high-risk profile for WD.

Anaemia is a frequently diagnosed condition which can develop as a consequence of numerous factors, including infectious diseases (IDs). Travelling, especially in sub-/tropical regions, leads to an elevated risk of contracting IDs. The aim of our study was to assess the epidemiological significance of IDs in inducing anaemia among a large cohort of returned travellers. This was a cross-sectional study in which data on 17,009 returned travellers aged 20-49 years who consulted the travel medicine clinic of the University of Munich between 1999 and 2011 were retrieved and analysed. Of the returned travellers, 8.3 % (6.0 % of males/10.4 % of females) were diagnosed with anaemia. The prevalence of anaemia was significantly elevated among patients of African (21.4/28.3 %) and Asian (11.6/15.7 %) origin. When the study population was restricted to the 14,636 travellers of German origin, 7.1 % of the returned travellers (4.6/9.6 %) were diagnosed with anaemia. The prevalence was significantly elevated among patients who travelled for >30 days (5.7 of males/10.6 % of females) and for male travellers visiting friends and relatives (7.7 %). However, these correlations were confounded by malaria. The prevalence of anaemia was significantly elevated only among returned travellers diagnosed with malaria (36.1 of males/26.9 % of females) and with symptomatic intestinal Entamoeba histolytica infections (30.0/33.3 %). Following the exclusion of confounding by malaria from the statistical analysis, the prevalence of anaemia was found to be significantly elevated among patients of African and Asian origin, and among patients of German origin who had travelled for >30 days, it could be mainly attributable to chronic, long-lasting causes. Although more than 550 travel-associated IDs were assessed in our study, only symptomatic intestinal Entamoeba histolytica infections and, to an even larger extent, malaria were determined to be of epidemiological significance for inducing anaemia among travellers.

This study was conducted to evaluate the incidence of severe lacerations during forceps delivery and the risk factors associated with such delivery in a hospital where simulation training is held annually. The medical records of 857 women who underwent forceps delivery at term with singleton cephalic presentation from 2010 to 2015 were reviewed. The relationship between clinical characteristics and birth canal trauma was analyzed. Birth canal trauma included third and fourth degree perineal lacerations. Univariable and multivariable models of logistic regression were employed to estimate the raw odds ratio and were adjusted for cofactors with 95% confidence intervals. Statistical significance was defined as P < 0.05. The incidence of severe lacerations was 10.1%. Birth weight, fetal head station, the rate of malrotation and the number of extractions were higher in women with severe lacerations (P < 0.01), whereas the use of obstetric anesthesia was lower in women with such lacerations (P < 0.01). Neither the indication for forceps delivery nor the qualifications of the operator had any influence on the incidence of severe lacerations. The incidence of severe lacerations was relatively low. Risk factors for severe lacerations with forceps delivery were identified as birth weight, fetal head station, malrotation and the number of extractions. Obstetric anesthesia may protect against severe lacerations. © 2018 Japan Society of Obstetrics and Gynecology.

The diagnosis of intestinal parasitic infections depends on the parasite load, the specific gravity density of the parasite eggs, oocysts or cysts, and the density and viscosity of flotation or sedimentation medium where faeces are processed. To evaluate the concordance between zinc sulphate flotation and centrifugal sedimentation in the recovery of parasites in faecal samples of children. Faecal samples of 330 children from day care centers were evaluated by zinc sulphate flotation and centrifugal sedimentation techniques. The frequencies of detection of parasites by each method were determined and the agreement between the diagnostic techniques was evaluated using the kappa index, with 95% confidence intervals. The faecal flotation in zinc sulphate diagnosed significantly more cases of Trichuris trichiura infection when compared to centrifugal sedimentation (39/330; 11.8% vs. 13/330; 3.9%, p<0.001), with low diagnostic concordance between methods (kappa=0.264; 95% CI: 0.102-0.427). Moreover, all positive samples for Enterobius vermicularis eggs (n=5) and Strongyloides stercoralis larvae (n=3) were diagnosed only by zinc sulphate. No statistical differences were observed between methods for protozoa identification. The results showed that centrifugal flotation in zinc sulphate solution was significantly more likely to detect light helminths eggs such as those of T. trichiura and E. vermicularis in faeces than the centrifugal sedimentation process.

The role of nurses and dietitians in managing paediatric coeliac disease.

PubMed

Fok, Chi-Yee; Holland, Kate Sara; Gil-Zaragozano, Elena; Paul, Siba Prosad

Coeliac disease (CD) is an immune-mediated genetic condition elicited by the ingestion of gluten, leading to proximal small bowel enteropathy. It affects around 1% of the population, although only a small proportion of cases are actually diagnosed. It is a multisystem disorder presenting with both gastrointestinal and extra-intestinal manifestations such as diarrhoea, abdominal pain, constipation, vomiting, iron deficiency anaemia, faltering growth, dental enamel defects, short stature, liver disease, arthropathy and recurrent aphthous ulcers. Nurses, working in different clinical settings, are best placed for early recognition and diagnosis of CD in children. Suspicion of CD should lead to immunoglobulin A (IgA)-based anti-tissue transglutaminase antibody screening tests and a diagnosis confirmed by an intestinal biopsy. Modification of European (ESPGHAN) guidelines now enables CD to be diagnosed without a small-bowel biopsy in a select group of symptomatic children. A gluten-free diet should preferably be started by paediatric dietitians. Strict adherence to a gluten-free diet is essential to maintain good health and to prevent long-term complications. A case study demonstrating some of the challenges that may be faced in children with CD in clinical practice is described. Specialist nurse-led CD clinics are gaining popularity and have been found to be equally effective in providing continuity of quality care.

Unsafe drinking water, unimproved sanitation and lack of hygiene pose health risks, particularly to children in low- and middle-income countries. This study aimed to assess the prevalence and risk factors of intestinal parasitic infections in school-aged children in two regions of Burkina Faso. A cross-sectional survey was carried out in February 2015 with 385 children aged 8-14 years from eight randomly selected schools in the Plateau Central and Centre-Ouest regions of Burkina Faso. Stool samples were subjected to the Kato-Katz and a formalin-ether concentration method for the diagnosis of helminths and intestinal protozoa infections. Urine samples were examined with a urine filtration technique for Schistosoma haematobium eggs. Water samples from community sources (n = 37), children's households (n = 95) and children's drinking water cups (n = 113) were analysed for contamination with coliform bacteria and faecal streptococci. Data on individual and family-level risk factors were obtained using a questionnaire. Mixed logistic regression models were employed to determine factors associated with intestinal parasitic infections in schoolchildren. Intestinal parasitic infections were highly prevalent; 84.7 % of the children harboured intestinal protozoa, while helminth infections were diagnosed in 10.7 % of the children. We found significantly lower odds of pathogenic intestinal protozoa infection (Entamoeba histolytica/E. dispar and Giardia intestinalis) among children from the Plateau Central, compared to the Centre-Ouest region (P < 0.001). Children from households with "freely roaming domestic animals" (P = 0.008), particularly dogs (P = 0.016) showed higher odds of G. intestinalis, and children reporting exposure to freshwater sources through domestic chores had higher odds of S. haematobium infection compared to children without this water contact activity (P = 0.035). Water quality, household drinking water source and storage did not emerge as significant risk factors for intestinal parasitic infections in children. Intestinal protozoa but not helminths were highly prevalent among schoolchildren in randomly selected schools in two regions of Burkina Faso. Our findings call for specific public health measures tailored to school-aged children and rural communities in this part of Burkina Faso. It will be interesting to assess the effect of water, sanitation and hygiene interventions on the transmission of intestinal parasitic infections. ISRCTN17968589 (date assigned: 17 July 2015).

The objective of this study was to determine some common behavioural risk factors for intestinal helminthiasis in nursery and primary school children in Enugu. A cross-sectional survey on 460 children attending nursery and primary schools in Enugu was carried out in 2003 with a view to determine some behavioural risk factors for intestinal helminthiasis. This study was carried out in the research laboratory of the Federal Ministry of Health, National Arbovirus and Vector Research Centre, Enugu. Intestinal helminthiasis was diagnosed using the kato-katz method in analysing fresh stool samples collected from nursery and primary school children in Enugu. These fresh stool samples were collected into appropriately labeled clean containers. Questionnaires were administered by the researchers to obtain data from the children and their parents or guardians as regards some behavioural risk factors for intestinal helminthiasis. The results from this study showed that the prevalence of intestinal helminthiasis was significantly affected by various behavioural risk factors. The rate of helminthic infection varied significantly with hand washing habits after defeacation (chi2 = 75.77; df= 2; p = 0.001) and with different habits of washing fruits before eating (chi2 = 52.79; df=2; p = 0.001) among the pupils. Also, the rate ofhelminthic infection varied significantly with the source of drinking water (chi2 = 55.12; df = 3; p = 0.01), water boiling habits (chi2 = 40.89; df = 2; p = 0.001), use of footwear after school hours (chi2 = 30.72; df = 2; p = 0.001). Sites utilized for defeacation by the pupils (chi2 = 80.25; df=3; p = 0.001) also significantly influenced the rate ofhelminthic infection. Various behavioural factors which significantly affect the rate of helminthic infection abound in children living in Enugu. The government should give attention to the control of these behavioural risk factors. A lot of health education will be needed to curb the poor personal hygienic habits which are obvious risk factors for intestinal helminthiasis.

A 68-year-old man visited an emergency department complaining of dyspnea. He was diagnosed to have Legionella pneumonia with multiple organ failure. Although his multiple organ failure improved, he suffered from persistent abdominal pain and diarrhea with continuous minor bleeding. Colonoscopy revealed a longitudinal ulcer of the rectum, below the peritoneal reflection. He was diagnosed with cytomegalovirus (CMV) colitis. Antiviral therapy with ganciclovir was initiated. He finally underwent a colostomy after a bowel stricture caused an intestinal outlet obstruction, which made oral intake impossible. Based on the present case, we believe that CMV colitis must be considered as one of the differential diagnoses when critically ill patients develop continuous diarrhea and abdominal pain.

Carpenter syndrome is an autosomal recessive disorder comprising craniosynostosis, polysyndactyly, and brachydactyly. It occurs in approximately 1 birth per million. We present a patient with Carpenter syndrome (confirmed by molecular diagnosis) who has several unique and previously unreported manifestations including a large ovarian cyst and heterotaxy with malrotation of stomach, intestine, and liver. These findings were first noted by prenatal ultrasound and may assist in prenatally diagnosing additional cases of Carpenter syndrome. © 2014 Wiley Periodicals, Inc.

Adult and immature rictulariid nematodes were recovered at necropsy from the small intestine of an adult slow loris, Nycticebus coucang, from the Milwaukee County Zoo in Wisconsin. The lumen of the entire small intestine was packed with more than 100 nematodes, the intestinal wall appeared thickened and the mucosal surface contained numerous petechial hemorrhagic foci. The cause of death was diagnosed as a septicemia and possible lupus erythematosis.

Congenital absence of the portal vein (CAPV) is a rare anomaly in which the intestinal and splenic venous drainage bypasses the liver and drains into the systemic veins through various venous shunts. In patients with CAPV, the portosystemic shunting causes disruption of the enterohepatic circulation and leads to various clinical manifestations. CAPV can be diagnosed without invasive techniques. This article illustrates the clinical and radiologic findings (including ultrasound, CT, and MRI) of CAPV.

Pneumatosis cystoides intestinalis, four cases of a rare disease.

2002-03-01

Pneumatosis cystoides intestinalis (PCI) is a disease in which small gas-filled cysts appear in the intestinal wall. Four cases presented here demonstrate the diversity of the associated diseases. In two of the patients constipation probably played a role; in the third patient decreased colonic motility, elevated intestinal pressure and increased mucosal permeability in the context of enteritis treated with codeine was the underlying problem; in the fourth high protein feeding and bowel ischaemia was diagnosed. Various aetiologies are presented in the literature. There is no specific history and physical or laboratory findings do not help to diagnose PCI. Plain abdominal film, ultrasound, computer tomography, magnetic resonance imaging, barium contrast studies and/or endoscopy may be necessary for diagnosis. Therapy is based on enhancing partial oxygen pressure in the bowel wall. PCI usually runs a benign course.

Prenatal Diagnosis of a Segmental Small Bowel Volvulus with Threatened Premature Labor

2017-01-01

Fetal primary small bowel volvulus is extremely rare but represents a serious life-threatening condition needing emergency neonatal surgical management to avoid severe digestive consequences. We report a case of primary small bowel volvulus with meconium peritonitis prenatally diagnosed at 27 weeks and 4 days of gestation during threatened premature labor with reduced fetal movements. Ultrasound showed a small bowel mildly dilated with thickened and hyperechogenic intestinal wall, with a typical whirlpool configuration. Normal fetal development allowed continuation of pregnancy with ultrasound follow-up. Induction of labor was decided at 37 weeks and 2 days of gestation because of a significant aggravation of intestinal dilatation appearing more extensive with peritoneal calcifications leading to the suspicion of meconium peritonitis, associated with reduced fetal movements and reduced fetal heart rate variability, for neonatal surgical management with a good outcome.

To investigate all patients referred to our center with non-responsive celiac disease (NRCD), to establish a cause for their continued symptoms. We assessed all patients referred to our center with non-responsive celiac disease over an 18-mo period. These individuals were investigated to establish the eitiology of their continued symptoms. The patients were first seen in clinic where a thorough history and examination were performed with routine blood work including tissue transglutaminase antibody measurement. They were also referred to a specialist gastroenterology dietician to try to identift any lapses in the diet and sources of hidden gluten ingestion. A repeat small intestinal biopsy was also performed and compared to biopsies from the referring hospital where possible. Colonoscopy, lactulose hydrogen breath testing, pancreolauryl testing and computed tomography scan of the abdomen were undertaken if the symptoms persisted. Their clinical progress was followed over a minimum of 2 years. One hundred and twelve consecutive patients were referred with NRCD. Twelve were found not to have celiac disease (CD). Of the remaining 100 patients, 45% were not adequately adhering to a strict gluten-free diet, with 24 (53%) found to be inadvertently ingesting gluten, and 21 (47%) admitting non-compliance. Microscopic colitis was diagnosed in 12% and small bowel bacterial overgrowth in 9%. Refractory CD was diagnosed in 9%. Three of these were diagnosed with intestinal lymphoma. After 2 years, 78 patients remained well, eight had continuing symptoms, and four had died. In individuals with NRCD, a remediable cause can be found in 90%: with continued gluten ingestion as the leading cause. We propose an algorithm for investigation.

Strongyloides stercoralis hyperinfection associated with impaired intestinal motility disorder

2015-01-01

Infection by Strongyloides stercoralis is a highly prevalent helminthiasis, which is mostly distributed in the tropical and subtropical regions of the world. Although a substantial number of cases are asymptomatic or paucisymtomatic, severe and life-threatening forms of this infection still occur and not infrequently is lately diagnosed. Gram-negative bacteria septicemia, which frequently accompanies the severe helminthiasis, contributes to the high mortality rate. Severe infection is invariably triggered by any imbalance in the host's immunity, favoring the auto-infective cycle, which increases the intraluminal parasite burden enormously. Clinical presentation of severe cases is varied, and diagnosis requires a high suspicion index. Acute abdomen has been reported in association with S. stercoralis infection, but intestinal necrosis is rarely found during the surgical approach. The authors report the case of a man who sought the emergency unit with recent onset abdominal pain. Clinical and imaging features were consistent with obstructive acute abdomen. Scattered adhesions and a necrotic ileal segment with a tiny perforation represented the surgical findings. The patient outcome was unfavorable and respiratory distress required an open lung biopsy. Both surgical specimens showed S. stercoralis infection. Unfortunately the patient underwent multiple organ failure and septicemia, and subsequently died. The authors call attention to the finding of intestinal necrosis and impaired intestinal motility disorder as possibilities for the diagnosis and risk factor, respectively, for a severe infection of S. stercoralis.

Protozoa are important enteric pathogens in patients with human immunodeficiency virus (HIV) infection. In this study the prevalence of intestinal protozoa in 154 HIV-infected patients, with or without diarrhoea, in our region (Apulia, South Italy) was evaluated between December 1993 and February 1998. In the majority of patients CD4+ T cell count was below 200/microl. The overall prevalence of intestinal protozoa was 43/154 (27.92%). Twenty-eight (43.08%) out of 65 patients with diarrhoea and 15 (16-85%) out of 89 non-diarrhoeic patients were parasitized. In particular, in the group of 65 patients with diarrhoea the following protozoa were identified: Cryptosporidium parvum in 14 (21.54%), Blastocystis hominis in 7 (10.77%), microsporidia in 6 (9.23%), Giardia lamblia in 4 (6.15%) and Isospora belli in 1 (1.54%). Three patients were Cryptosporidium parvum-microsporidia co-infected. In patients without intestinal symptoms, prevalence was 3/89 (3.37%) for Cryptosporidium parvum, 9/89 (10.11%) for Blastocystis hominis, 1/89 (1.12%) for microsporidia and 2/89 (2.25%) for Giardia lamblia. A significant (P<0.001) correlation was observed between protozoan infection and the presence of diarrhoea. In particular, Cryptosporidium parvum and microsporidia infections were significantly (P<0.001) and P = 0.046, respectively) associated with diarrhoeal illness. Moreover, the majority of cases of cryptosporidiosis were first diagnosed in the periods of heaviest rainfall. Therefore, drinking water contamination may be a possible source of human infection in our area. PMID:10694157

Severity of chronic gastritis associated with Helicobacter pylori infection (CGAHpI) could play a role in evaluating the potential risk to develop gastric cancer. Our aim was to estimate the risk for gastric cancer in a clinical setting, according to histopathologic criteria, by applying the gastric cancer risk index (GCRI) METHODS: Histopathologic study of the gastric biopsies (corpus-antrum) from consecutive adult patients that underwent gastroesophageal duodenoscopy was carried out, and the GCRI was applied in patients presenting with CGAHpI. One hundred eleven patients (77% female) with a mean age of 38.6±13.1 years were included. Active Helicobacter pylori infection (aHpi) was diagnosed in 77 cases (69.40%). In 45% of the cases with aHpi, pangastritis (23%) or corpus-predominant gastritis (22%) was diagnosed. Nine cases were diagnosed with intestinal metaplasia (8%), 7 of which (77.70%) were in the aHpi group. Twenty one percent of the patients with aHpi had a GCRI of 2 (18.10%) or 3 (2.50%) points (high risk index), while 79.10% accumulated a GCRI of 0 or 1 points (low risk index). Of the patients with no aHpi, none of them had 3 points (p=0.001). Of the 18 patients that accumulated 2 or 3 points, 6 (33.30%) presented with intestinal metaplasia (all with pangastritis and corpus-predominant gastritis), of which 4 cases (66.60%) had aHpi. The estimated gastric cancer risk in patients with CGAHpI in the clinical setting studied was relatively low and 5% of the patients had a histopathologic phenotype associated with an elevated risk for developing gastric cancer.

A potential link between small intestinal bacterial overgrowth (SIBO) and abdominal pain-related functional gastrointestinal disorders (AP-FGID) has been suggested by symptom similarities and by the reported prevalence of SIBO in children with irritable bowel syndrome (IBS) and functional AP. The aim of this study is to evaluate the prevalence of SIBO using the glucose hydrogen breath test (GHBT), in a cohort of Dutch children with AP-FGID fulfilling the Rome III criteria, and to identify potential predictors. Children ages 6 to 18 years with AP-FGID fulfilling the Rome III criteria were included. All of the children underwent a GHBT. SIBO was diagnosed if the fasting breath hydrogen concentration was ≥20 ppm or an increase in H2 levels of ≥12 ppm above the baseline value was measured after ingestion of glucose. Gastrointestinal symptoms were collected using a standardised AP questionnaire. A total of 161 Dutch children with AP-FGID were enrolled. Twenty-three patients (14.3%) were diagnosed as having SIBO, as assessed by GHBT; 78% of the children diagnosed as having SIBO had fasting hydrogen levels ≥20 ppm. IBS was significantly more found in children with SIBO compared with children without SIBO (P = 0.001). An altered defecation pattern (ie, change in frequency or form of stool) (P = 0.013), loss of appetite (P = 0.007), and belching (P = 0.023) were significantly more found in children with SIBO compared with those without SIBO. SIBO is present in 14.3% of children presenting with AP-FGID. IBS, altered defecation pattern, loss of appetite, and belching were predictors for SIBO in children with AP-FGID.

The value of methylene blue-directed biopsies (MBDB) in detecting specialized intestinal metaplasia and dysplasia in Barrett's esophagus remains unclear. The aim of this study was to compare the accuracy of MBDB with random biopsy in detecting intestinal metaplasia and dysplasia in patients with Barrett's esophagus. A prospective, randomized, cross-over trial was undertaken to compare MBDB with random biopsy in patients with Barrett's esophagus segments 3 cm or more in length without macroscopic evidence of dysplasia or cancer. Dysplasia was graded as: indefinite for dysplasia, low-grade dysplasia, high-grade dysplasia, or carcinoma, and was reported in a blinded fashion. Fifty-seven patients were recruited, 44 of whom were male. A total of 1,269 biopsies were taken (MBDB-651, random biopsie-618). Analysis of the results by per-biopsy protocol showed that the MBDB technique diagnosed significantly more specialized intestinal metaplasia (75 %) compared to the random biopsy technique (68 %; P = 0.032). The sensitivity and specificity rates of MBDB for diagnosing specialized intestinal metaplasia were 91 % (95 % CI, 88 - 93 %) and 43 % (95 % CI, 36 - 51 %), respectively. The sensitivity and specificity rates of MBDB for diagnosing dysplasia or carcinoma were 49 % (95 % CI, 38 - 61 %) and 85 % (95 % CI, 82 - 88 %), respectively. There were no significant differences in the diagnosis of dysplasia and carcinoma - MBDB 12 %, random biopsy 10 %. The methylene blue staining pattern appeared to have an influence on the detection of specialized intestinal metaplasia and dysplasia/carcinoma. Dark blue staining was associated with increased detection of specialized intestinal metaplasia (P < 0.0001), and heterogeneous staining (P = 0.137) or no staining (P = 0.005) were associated with dysplasia and/or carcinoma detection. The MBDB technique prolonged the endoscopy examination by an average of 6 min. The diagnostic accuracy of the MBDB technique was superior to that of the random biopsy technique for identifying specialized intestinal metaplasia, but not dysplasia or carcinoma. The intensity of methylene blue staining has an influence on the detection of specialized intestinal metaplasia and dysplasia or carcinoma, which may help in targeting the biopsies. Although MBDB prolongs the endoscopy procedure slightly, it is a safe and well-tolerated procedure. Further clinical studies on the MBDB technique exclusively in endoscopically normal dysplastic Barrett's esophagus are needed.

Background Among congenital heart disease (CHD) patients, the coexistence of non-cardiac congenital anatomic abnormalities (NC), genetic abnormalities (GA), and syndromes (S) may influence therapeutic strategies and outcomes. The appreciated prevalence of these abnormalities has risen, as increased screening and improved diagnostic precision enable identification of these comorbidities in a larger fraction of neonates with CHD. We examined the contemporary prevalence and distribution of NC/GA/S across diagnostic groups among neonates undergoing cardiac surgery using a large, nationally representative clinical registry. Methods The Society of Thoracic Surgeons-Congenital Heart Surgery Database (STS-CHSD) was queried to identify neonates (≤ 30 days) who underwent index cardiac operations from 2010–2013. The fundamental cardiac diagnosis was used to identify 10 diagnostic groups. The prevalence of NC/GA/S was reported across each group. Results The cohort included 15,376 index neonatal operations from 112 centers. Overall 18.8% (2,894/15,376) of operations were performed on neonates with NC/GA/S. Patients with atrioventricular septal defect (212/357, 59.4%), interrupted aortic arch (248/567, 43.7%), truncus arteriosus (204/554, 36.8%), tetralogy of Fallot (417/1383, 30.2%) had the highest prevalence of NC/GA/S abnormalities, whereas those with transposition (111/2778, 4.0%) had the lowest prevalence. The most commonly identified NC/GA/S included: heterotaxy (597/15,376, 3.9%), DiGeorge/22q11 deletion (550/15,376, 3.6%), Down syndrome/trisomy 21 (318/15, 376, 2.1%), intestinal malrotation (220/15,376, 1.4%), and Turner syndrome/45XO (189/15,376, 1.2%). Conclusions The prevalence of NC/GA/S varies widely across CHD diagnostic groups. This information may be useful for patient counseling, recommendations for screening for anomalies and genetic disorders, and perioperative management. PMID:27319986

Management of a child with vomiting.

PubMed

Singhi, Sunit C; Shah, Ravi; Bansal, Arun; Jayashree, M

2013-04-01

Vomiting is a protective reflex that results in forceful ejection of stomach contents up to and out of the mouth. It is a common complaint and may be the presenting symptom of several life-threatening conditions. It can be caused by a variety of organic and nonorganic disorders; gastrointestinal (GI) or outside of GI. Acute gastritis and gastroenteritis (AGE) are the leading cause of acute vomiting in children. Important life threatening causes in infancy include congenital intestinal obstruction, atresia, malrotation with volvulus, necrotizing enterocolitis, pyloric stenosis, intussusception, shaken baby syndrome, hydrocephalus, inborn errors of metabolism, congenital adrenal hypoplasia, obstructive uropathy, sepsis, meningitis and encephalitis, and severe gastroenteritis, and in older children appendicitis, intracranial mass lesion, diabetic ketoacidosis, Reye's syndrome, toxic ingestions, uremia, and meningitis. Initial evaluation is directed at assessment of airway, breathing and circulation, assessment of hydration status and red flag signs (bilious or bloody vomiting, altered sensorium, toxic/septic/apprehensive look, inconsolable cry or excessive irritability, severe dehydration, concern for symptomatic hypoglycemia, severe wasting, Bent-over posture). The history and physical examination guides the approach in an individual patient. The diverse nature of causes of vomiting makes a "routine" laboratory or radiologic screen impossible. Investigations (Serum electrolytes and blood gases,renal and liver functions and radiological studies) are required in any child with dehydration or red flag signs, to diagnose surgical causes. Management priorities include treatment of dehydration, stoppage of oral fluids/feeds and decompression of the stomach with nasogastric tube in patients with bilious vomiting. Antiemetic ondansetron(0.2 mg/kg oral; parenteral 0.15 mg/kg; maximum 4 mg) is indicated in children unable to take orally due to persistent vomiting, post-operative vomiting, chemotherapy induced vomiting, cyclic vomiting syndrome and acute mountain sickness.

Toxocara eggs shed by dogs and cats and their molecular and morphometric species-specific identification: is the finding of T. cati eggs shed by dogs of epidemiological relevance?

Intestinal infections with Toxocara cati and Toxocara canis in their definitive host (felids and canids, respectively) are diagnosed by egg identification in faeces using coproscopical techniques. The Toxocara species is assumed to comply with the species from which the examined faeces were obtained, i.e. T. cati in cats and T. canis in dogs. We isolated and measured Toxocara eggs from faecal samples of 36 cats and 35 dogs from Switzerland and identified the Toxocara species by PCR. Amongst the isolates originating from dogs, 24 (68.5%) were determined as T. canis and 11 (31.5%) as T. cati. In all samples originating from cats, only T. cati was identified. Based on PCR identification, eggs of T. canis (n=241) and T. cati (n=442) were measured, revealing statistically significant different (p<0.001) mean sizes of 62.3 by 72.7 μm for T. cati and 74.8 by 86.0 μm for T. canis eggs. Considering that coprophagy is not unusual for dogs, a considerable percentage of Toxocara infections coproscopically diagnosed in dogs, as well as assumptions on anthelminthic resistance in regularly treated dogs, might in fact relate to intestinal passages of eggs following the uptake of other animals' faeces.

To give an overview of the literature on left-sided acute appendicitis (LSAA) associated with situs inversus totalis (SIT) and midgut malrotation (MM). We present a new case of LSAA with SIT and a literature review of studies published in the English language on LSAA, accessed via PubMed and Google Scholar databases. Ninety-five published cases of LSAA were evaluated and a 25-year-old female, who presented to our clinic with left lower abdominal pain caused by LSAA, is reported. In the reviewed literature, fifty-seven patients were male and 38 were female with an age range of 8 to 82 years and a median age of 29.1 ± 15.9 years. Sixty-six patients had SIT, 23 had MM, three had cecal malrotation, and two had a previously unnoted congenital abnormality. Fifty-nine patients had presented to the hospital with left lower, 14 with right lower and seven with bilateral lower quadrant pain, and seven subjects complained of left upper quadrant pain. The diagnosis was established preoperatively in 49 patients, intraoperatively in 19, and during the postoperative period in five; 14 patients were aware of having this anomaly. The data of eight patients were not unavailable. Eleven patients underwent laparoscopic appendectomy, which was combined with cholecystectomy in two cases. Histopathological examination of the appendix specimens revealed adenocarcinoma in only two of 95 patients. The diagnosis of left lower quadrant pain is based on well-established clinical symptoms, physical examination and physician's experience.

Whipple's disease (WD) is a rare systemic disease of infectious etiology which involves the small intestine but can virtually affect any organ. We present here five cases (four males and one female) ranging in age from 20 to 59 years. All patients had intestinal involvement associated or not with clinical manifestations linked to this organ. Vegetation in the tricuspid valve was observed in one patient, suggesting endocarditis caused by Tropheryma whippelii, with disappearance of the echocardiographic alterations after treatment. In one of the male patients the initial clinical manifestation was serologically negative spondylitis, with no diarrhea occurring at any time during follow-up. Ocular involvement associated with intestinal malabsorption and significant weight loss were observed in one case. In the other two cases, diarrhea was the major clinical manifestation. All patients were diagnosed by histological examination of the jejunal mucosa and, when indicated, of extraintestinal tissues by light and electron microscopy. After antibiotic treatment, full remission of symptoms occurred in all cases. A control examination of the intestinal mucosa performed after twelve months of treatment with sulfamethoxazole-trimethoprim revealed the disappearance of T. whippelii in four patients. The remaining patient was lost to follow-up.

Reports of conversion in cases of locally advanced colorectal cancer have been increasing. Here, we present 2 cases in which curative resection of locally advanced rectal cancer accompanied by intestinal obstruction was achieved after establishing a stoma and administering chemotherapy. The first case was of a 46-year-old male patient diagnosed with upper rectal cancer and intestinal obstruction. Because of a high level of retroperitoneal invasion, after establishing a sigmoid colostomy, 13 courses of mFOLFOX6 plus Pmab were administered. Around 6 months after the initial surgery, low anterior resection for rectal cancer and surgery to close the stoma were performed. Fourteen days after curative resection, the patient was discharged from the hospital. The second case was of a 66-year-old male patient with a circumferential tumor extending from Rs to R, accompanied by right ureter infiltration and sub-intestinal obstruction. After establishing a sigmoid colostomy, 11 courses of mFOLFOX6 plus Pmab were administered. Five months after the initial surgery, anterior resection of the rectum and surgery to close the stoma were performed. Twenty days after curative resection, the patient was released from the hospital. No recurrences have been detected in either case.

Methamphetamine (METH) abuse is increasing rapidly all over the world and becoming a significant public health concern in China. However, abdominal complications secondary to METH abuse are usually overlooked. We describe an unusual case of gangrenous cholecystitis and small intestinal ischemia due to METH abuse. In this report, a 44-year-old male patient with abdominal pain and hematochezia has a history of crystal meth abuse. The patient was diagnosed as septic shock, paralytic ileus, gangrenous cholecystitis, and small intestinal ischemia due to METH abuse based on computed tomography (CT) scan, endoscopy examination, laparotomy, and pathology. Antishock treatment, broad-spectrum antibiotics, and exploratory laparotomy were given. The patient survived. Six months later, he tolerated oral intake and stopped using crystal METH. Visceral ischemia should be considered if an adult patient with a history of METH abuse is accompanied by abdominal pain and hematochezia.

We present a case of cerebral Scedosporium apiospermum infection presenting with intestinal manifestations in a 64-year-old male patient on immunosuppression for orthotopic liver transplantation. At admission, the patient's chief complaint was chronic watery diarrhea and he was found to have colonic ulcers on endoscopy. His hospital course was complicated by a tonic-clonic seizure caused by a left frontal brain abscess, with the causative agent being identified by culture. He was treated with lobectomy, high-dose intravenous voriconazole, and liposomal amphotericin with clinical, endoscopic, and histologic improvement. To our knowledge, S. apiospermum has not been previously described as a cause of colitis. The septate branching appearance of the Scedosporium species is similar to the more common Aspergillus species. This case of gastrointestinal Scedosporium brings into question previously reported cases of isolated gastrointestinal aspergillosis diagnosed by histopathology. Clinical suspicion for S. apiospermum must be maintained in immunosuppressed patients presenting with neurologic and gastrointestinal symptoms.

A 48-year-old man noticed nausea and took health examination. After chest X-ray and gastrointestinal barium study was underwent, he was referred to our hospital because of abnormal shadow in the chest X-ray. CT scan revealed about 4 cm tumor in the hilum of left lung and target sign in the small intestine. He was diagnosed with intussusception and emergency operation was performed. During the laparotomy, we found 2 intussusceptions in the small intestine and we performed manual reduction using Hutchinson's maneuver. We confirmed the mass in oral side of the intussusception site but we did not confirmed any tumor in anal of the intussusception. This suggests the intussusception was caused by barium. Finally 3 small intestine tumor was observed and we resected and reconstructed each of the tumor. Histopathological examination showed small intestinal metastasis from pleomorphic carcinoma of the lung.

BACKGROUND Intestinal Behçet's disease-like symptoms are rare complications of myelodysplastic syndrome and are often refractory to immunosuppressive therapies. We described a case of myelodysplastic syndrome complicated by Behçet's disease-like symptoms treated with prednisolone and azacitidine. CASE REPORT A 68-year-old Japanese woman was admitted to our hospital because of persistent high fever and lower abdominal pain. Oral ulcerations developed after admission, and multiple ulcers were found in her terminal ileum by endoscopic examination. She was diagnosed with myelodysplastic syndrome with trisomy 8 by bone marrow examination. Her symptoms diminished after administration of prednisolone, but relapsed afterwards. She began azacitidine therapy and her symptoms have been controlled for at least 10 months. CONCLUSIONS This case might suggest the possibility of azacitidine as a treatment option for myelodysplastic syndrome complicated by Behçet's disease-like symptoms.

The classic diagnosis of Barret esophagus is based on the finding of three of more cm of distal esophagus covered by specialized columnar epithelium. However, at the present time, it is based on the presence of intestinal metaplasia in the junction of squamous-columnar mucosae. To assess the prevalence of Barret esophagus using endoscopic and pathological criteria in healthy subjects and in individuals with gastroesophageal reflux. One hundred thirty nine controls and 372 patients with symptoms of gastroesophageal reflux subjected to an upper gastrointestinal endoscopy were studied. Patients with Barret esophagus were classified as having a "mini Barret" when the pathological presence of intestinal metaplasia was the only finding. A "short Barret esophagus" was diagnosed when less than 3 cm were covered with fingerings of mucosal substitutions and "extensive Barret esophagus" when more than 3 cm of esophageal mucosa were substituted. Two percent of controls, 12.4% of patients with gastroesophageal reflux without esophagitis and 11.7% of such patients with esophagitis had intestinal metaplasia in the gastroesophageal junction. Patients with Barret esophagus were older than the rest of patients. "Short Barret esophagus" is six times more frequent than "extensive Barret esophagus". Esophageal erosions, peptic ulcers and stenosis were more frequent in patients with extensive Barret esophagus. The prevalence of dysplasia was similar in all types of Barret esophagus. Intestinal metaplasia was very infrequent in control patients. In subjects with gastroesophageal reflux, classic endoscopic diagnosis may miss up to 80% of patients with Barret esophagus. Thus, gastroesophageal junction biopsies must be obtained in all patients with symptoms of gastroesophageal reflux.

It was analyzed the results of treatment of 48 children aged from 1 month to 14 years. In these observations by the 6th - 7th days after doubleintestinalstoma formation magnetic dies with inductance from 300 to 360 mTl and energy force at least 255 kJ/m3 were introduced into lumen of afferent and efferent intestinal loops. Attractive or compression force between dies was 600 g, i.e. force per 1 cm2 was 200 g according to dies' surface 1.12.83.0 cm. Magnets are not only surgical instruments but also physiotherapeutic devices improving microcirculation and stimulating regeneration in the area of anastomosis. Interintestinal anastomosis has been completely formed for 5-7 days. Thereafter magnetic dies have been removed. Stool was normalized in 45 of 48 observations after surgery (1-3 times daily). Intestinal discharge from ileostomy reduced to minimal amount. In 2 patients irregular bowel movements was observed due to adhesive stenosis of interintestinal anastomosis. Magnetic dies can't be established in 1 case due to adhesive process. Hospital stay was from 10 to 25 days in 41 children. 7 patients were discharged for outpatient treatment later. All children were under observation for the period 2-4 months after discharge. Signs of hypotrophy including body weight deficit within 10% of age norm were diagnosed only in 3 children with prematurity degree I-II. Hereafter children were repeatedly hospitalized; intestinal stomas were surgically removed using conventional technique. Thus complete convalescence was obtained.

A 60-year-old woman with a history of distal gastrectomy for gastric cancer presented with a chief complaint of epigastric pain. Duodenal ileus due to the migration of a gastric bezoar was diagnosed, and she was hospitalized. We performed endoscopic lithotripsy and injection of cola, but the bezoar migrated toward the anus. Her abdominal pain worsened the following day, and she was diagnosed with ileus induced by the gastric bezoar. After decompression with an ileus tube, 1000ml/day of cola was injected via the ileus tube, and the ileus resolved on the 5th day of therapy. Based on this experience, we believe that dissolution therapy with cola via an ileus tube is effective in the treatment of bezoar-induced small bowel ileus.

In the Orthopaedic Department in Patras University 427 intramedullary nailings in the lower limbs were performed between 1989 and 1994 and retrospectively reviewed to evaluate the range of complications. One hundred and seventy-two were nailings of the femur; 80 gamma nails mainly for subtrochanteric and intertrochanteric with subtrochanteric extension fractures were included, (total 252/59%); 175 (41%) were nailings of the tibia. Union was achieved in all case. Overall the complication rate in this series was 3.3% (14 cases) and included infection (4 cases), neuropraxia (2 cases), implant failure (5 cases), limb length deficiency (2 cases) and malrotation (1 case).

Hirschsprung disease is a developmental disorder of the enteric nervous system that is characterized by absence of ganglion cells in the distal intestine, and it occurs in approximately 1 in every 500,000 live births. Hepatoblastoma is a malignant liver neoplasm that usually occurs in children aged 6 months to 3 years, with a prevalence of 0.54 cases per 100,000. A boy diagnosed with intestinal atresia in the first week of life progressed to a diagnosis of comorbid Hirschsprung disease. Congenital cataracts and sensorineural deafness were diagnosed. A liver mass developed and was subsequently confirmed to be a hepatoblastoma, which was treated by means of surgical resection of 70% of the liver volume and neoadjuvant chemotherapy (ifosfamide, cisplatin and doxorubicin). It is known that Hirschsprung disease may be associated with syndromes predisposing towards cancer, and that hepatoblastoma may also be associated with certain congenital syndromes. However, co-occurrence of hepatoblastoma and Hirschsprung disease has not been previously described. We have reported a case of a male patient born with ileal atresia, Hirschsprung disease and bilateral congenital cataract who was later diagnosed with hepatoblastoma.

The posterior auricular muscle: a useful anatomical landmark for otoplasty.

PubMed

Stephen, C; Lowrie, A G

2017-05-01

The correct anatomical placement of conchomastoid sutures during suture otoplasty can sometimes prove challenging. If the suture vector is inaccurate, reduction can be difficult and this may lead to malrotation of the pinna. This paper describes the adoption of the auricularis posterior muscle, which runs from the mastoid to the concha and whose function is to adduct the pinna, as a marker for conchomastoid suture placement. The muscle is easily identified and dissected, providing a landmark for the placement of sutures onto the adjacent concha and mastoid fascia. This allows for an anatomical reduction of the pinna. It is believed that this approach will prove useful to the otoplasty surgeon.

Shiba dogs are predisposed to chronic enteropathy (CE) and have poorer prognosis than other dog breeds. The objective of this study was to investigate the significance of polymerase chain reaction for antigen receptor rearrangement (PARR) results on clinical findings and prognosis of Shiba dogs with CE. We retrospectively collected data on 22 Shiba dogs diagnosed as having CE. Fifty-nine percent of the dogs had clonality-positive results on PARR analysis. Furthermore, on histopathology, epitheliotropic behavior of small lymphocytes of the intestinal mucosa was observed significantly more frequently in dogs with clonal rearrangement of antigen receptor genes (P=0.027). The median overall survival time of clonality-positive dogs was 48 days (range, 4-239 days), compared to 271 days (range, 45-1,316+ days) in clonality-negative dogs. The median overall survival time of epitheliotropism-positive dogs was 76 days (range, 30-349 days) compared to 239 days (range, 4-1,316+ days) for epitheliotropism-negative dogs. Statistical analysis revealed that the clonality-positive result was associated with significantly shorter survival time (P=0.036). In contrast, presence or absence of epitheliotropism had no statistically significant effect on survival time (P=0.223). These cases might appropriately be diagnosed as small T-cell intestinal lymphoma; there are some common clinical and pathogenic features with human enteropathy-associated T-cell lymphoma type 2. The pathogenesis and poor prognosis for Shiba dogs with CE seem to be associated with this type of lymphoma, although further investigation is warranted.

Excessive flatulence which impairs social performance in patients is one of the common reasons for referrals to gastroenterology clinics. Celiac Disease is a rare but important cause of increased intestinal gas (bloating) and if not diagnosed, patients face complications such as malabsorption, anemia, osteoporosis and even intestinal lymphoma. This study aimed to determine the frequency of Celiac Disease in patients with excessive flatulence. One hundred and fifty patients with a chief complaint of experiencing flatulence more than 15 times a day and lasting for three months were referred to the gastroenterology clinic of Rasoul-e-Akram Teaching Hospital. Serological tests for Celiac Disease, Anti TTG Ab (IgA-IgG) were requested and the patients with positive tests underwent upper GI endoscopy. Biopsies of the second part of the duodenum were then sent to the laboratory. From one hundred and thirty patients who completed the study, 92 (70.7%) were female. Mean age of the patients was 32 ± 13 years. Anti TTG Ab was found in 5 patients (3.85%). Only 2 patients (1.5%) had a documented positive pathology for Celiac Disease. According to the results of this study and other studies, we conclude that Celiac Disease is an uncommon etiology for excessive flatulence but it is of importance to investigate it in excessive flatulence patients.

Pussepitiya, Kumari; Samarasinghe, Bandula; Wickramasinghe, Nuwan

2016-01-01

Introduction. Vitelline artery remnants are rare causes of intra-abdominal bands leading to bowel obstruction. These bands may be associated with Meckel's diverticulum. Double inferior vena cava (IVC) is a rare presentation and is usually identified incidentally. Case Presentation. A sixty-year-old male presented with progressive vomiting for five days and he was clinically diagnosed with intestinal obstruction. Plain X-ray abdomen showed evidence of small bowel obstruction. CT scan of the abdomen revealed dilated small bowel loops with a small outpouching in the distal ileum with a band like structure attached to it. In the CT, left sided patent IVC draining into the left renal vein was identified. Left external iliac vein was in continuity with the left IVC. Left internal iliac vein was draining into the right IVC. Exploratory laparotomy revealed a Meckel's diverticulum with a band identified as the vitelline remnant attached to its apex and inserting at the anterior abdominal wall near the umbilicus. Discussion. Meckel's diverticulum with vitelline bands, although rare, should be borne in mind in adult patients with intestinal obstruction. Identification of this anomaly can be difficult in imaging studies. Presence of double IVC should be mentioned in the imaging findings to prevent possible catastrophic complications during surgery.

Anisakiosis is a parasitic infection that follows consumption of raw or insufficiently pickled, salted, smoked, or cooked wild marine fish infected with Anisakis sp. larvae. We report a case of intestinal anisakiosis in a 50-year-old man from Quebec who presented with abdominal pain and peripheral eosinophilia after eating raw wild-caught salmon from the Pacific Ocean off Canada. Abdominal CT scan showed bowel distension proximal to a segmental jejunal wall thickening, which was resected. The jejunum segment showed a localized area of serositis with mucosal edema and a submucosal abscess rich in eosinophils surrounding a parasite consistent with the third larval stage of Anisakis sp. Diagnostic morphologic characteristics included an unpaired excretory gland (renette cell), Y-shaped lateral epidermal cords, no apparent reproductive system, and a ventriculus (glandular esophagus). These features and the absence of lateral alae excluded Ascaris sp. The absence of ventricular appendage and intestinal cecum excluded other anisakids of the genera Pseudoterranova and Contracaecum. As the popularity of eating raw fish is growing in North America, anisakiosis may be diagnosed more frequently in surgical specimens. This parasitic infection should be considered in the differential diagnosis of acute abdominal syndromes and eosinophilic infiltrates of the stomach, small intestine, colon, omentum, and mesentery, especially with a history of raw marine fish consumption.

Enrichment of sulfidogenic bacteria from the human intestinal tract.

Hydrogen sulfide is formed in the human intestinal tract as the end product of the anaerobic microbial degradation of sulfur compounds present in mucus, bile or proteins. Since human gut microbial sulfur metabolism has been poorly characterized, we aimed to identify and isolate the microorganisms involved in sulfide formation. Fresh fecal samples from one healthy donor and one diagnosed with irritable bowel syndrome were used as inocula for enrichments that were supplemented with sulfate or sulfite as electron acceptors in combination with different electron donors. After two transfers, cultures with high sulfide production were selected and the phylogenetic composition of the enriched microbial communities was determined. Sulfite respiration and cysteine degradation were the dominant sulfidogenic processes, and the most abundant bacteria enriched belonged to Bilophila and Clostridium cluster XIVa. Different isolates were obtained and remarkably included a novel sulfite reducer, designated strain 2C. Strain 2C belongs to the Veillonellaceae family of Firmicutes phylum and showed limited (91%) 16S rRNA gene sequence similarity with that of known Sporomusa species and hence may represent a novel genus. This study indicates that bacteria that utilize sulfite and organic sulfur compounds rather than merely sulfate are relevant for human intestinal sulfur metabolism. © FEMS 2017. All rights reserved.

Soil transmitted helminths and scabies in Zanzibar, Tanzania following mass drug administration for lymphatic filariasis - a rapid assessment methodology to assess impact

PubMed Central

2012-01-01

Background Ivermectin and albendazole are used in annual mass drug administration (MDA) for the lymphatic filariasis elimination programmes in African countries co-endemic for onchocerciasis, but have additional impact on soil transmitted helminths and the ectoparasitic mite which causes scabies. Assessing these collateral impacts at scale is difficult due to the insensitivity of available parasite detection techniques. Methods The numbers of cases diagnosed with intestinal helminths and scabies and who received prescriptions for treatment were evaluated in 50 health centres in Zanzibar. Records were examined from 2000, prior to the initiation of MDA to 2005, after six rounds of MDA for lymphatic filariasis had taken place. Results Health centre records showed a consistent decline in the number of cases of intestinal helminths and scabies diagnosed by community health workers in Zanzibar and the number of prescriptions issued across five age groups. A 90-98% decline in soil transmitted helminths and 68-98% decline in scabies infections were recorded. Poisson regression models aggregated to both the island-level and district-level indicated that the decline was statistically significant. Conclusions The described method of examining health centre records has the potential for use on a large scale, despite limitations, as a rapid method to evaluate the impacts resulting from both lymphatic filariasis and onchocerciasis MDA. This would result in a reduction in the need for parasitological evaluations to determine prevalence and intensity. PMID:23259465

Two cases of children diagnosed with renal tubular acidosis (RTA) associated with autoimmune hypothyroidism are presented. Case 1 developed an intestinal ileus at the age of five in the context of a respiratory problem. The tests performed confirmed metabolic acidosis, hyperchloraemia, hypokalaemia and nephrocalcinosis. Case 2 was diagnosed with hypothyroidism at the age of 11, and with RTA two years later. In both patients, the diagnosis of RTA was verified when decreased maximum urinary pCO 2 was found. In case 2, a proximal bicarbonate leak (type 3 RTA) was also confirmed. This was the first case to be published on the topic. The causes of RTA in patients with hypothyroidism are reviewed. The deleterious effect on the kidneys may be due to the absence of thyroid hormone and/or autoantibodies in the cases of autoimmune hypothyroidism. Copyright © 2018 Sociedad Española de Nefrología.

Leptospirosis is a widespread zoonosis, which is diagnosed less frequently in children than might be expected from the level of exposure to hazards, especially in tropical areas. A 15 1/2-year-old Gabonese boy was admitted following five days of fever, headache, myalgia, abdominal pain, diarrhea, intestinal bleeding, jaundice and conjunctival suffusion. Laboratory data showed abnormal liver and renal function tests, and diagnosis of Plasmodium falciparum malaria was confirmed by thin blood smear. The patient did not clinically improve despite antimalarial treatment and then leptospirosis was suspected. Serologic tests were performed and leptospirosis was later confirmed. Antibiotic treatment (cefuroxim) was given. The outcome was good, liver and renal tests returned to normal in a few days. In tropical area, leptospirosis should be considered in children who are diagnosed with either an unexplained fever, a pseudo-influenza syndrome, or jaundice with hepatorenal involvement and gastrointestinal bleeding.

Immigrants have a higher risk of contracting some infectious diseases. The aim of this study was to determine and compare the morbidity profile of immigrant children according to their country of origin. We performed a descriptive study of all immigrants aged less than 14 years old who attended the Tropical Medicine Unit of the Ramon y Cajal Hospital in Madrid between 1989 and 2001. A total of 170 children were included (73 % from Africa, 19 % from Latin America, and 5 % from Asia). Seventy-five percent had at least one infectious disease (78 % of Africans and 62 % of Latin Americans) and 27 % were co-infected (> 2 pathogenic agents). The proportion of healthy children was higher (p < 0.05) among Latin Americans (21 %) than among Africans (9 %). The most frequent infectious diseases were malaria (35 %), intestinal parasites (48 %), filariasis (23 %), and viral hepatitis (19 %). Malaria, filariasis and hepatitis were more frequent in Africans than in Americans (p < 0.05). Other helminthic infections (15 %) were more frequent in Americans. In both groups intestinal parasites and tuberculosis (6 %) were prevalent. Of the 36 (21 %) asymptomatic children, 53 % had at least one infectious disease. The most frequently diagnosed diseases in Africans were intestinal parasitosis (35 %), malaria (7 %), cured hepatitis B (15 %), filariasis (12 %) and superficial mycosis (4 %). The most frequent infectious diseases in Latin Americans were intestinal parasitosis (38 %) and visceral toxocariasis (25 %). Infectious diseases and co-infections are frequent in immigrant children, even in those who are asymptomatic. We propose screening of certain infectious diseases in these children according to their country of origin and their length of residence in Spain.

Some cases of seasonal influenza virus (human influenza A virus (IAV)/human influenza B virus (IBV)) are associated with abdominal symptoms. Although virus RNA has been detected in faeces, intestinal infection has not been clearly demonstrated. We aimed to provide evidence that IAV/IBV infects the human intestine. This prospective observational study measured virus RNA in faecal and sputum samples from 22 patients infected with IAV/IBV (19 IAV positive and three IBV positive). Nineteen patients were included in the analysis and were assigned to faecal IAV-positive and -negative groups. Virus kinetics were examined in faecal samples from an IAV-infected patient (patient 1) and an IBV-infected patient (patient 2). Finally, intestinal tissue from an IAV-diagnosed patient who developed haemorrhagic colitis and underwent colonoscopy was examined for the presence of replicating IAV (patient 3). Virus RNA was detected in faecal samples from 8/22 IAV/IBV-infected patients (36.4%). Diarrhoea occurred significantly more often in the faecal IAV-positive group (p 0.002). In patients 1 and 2, virus RNA became undetectable in sputum on days 7 and 10 after infection, respectively, but was detected in faeces for a further 2 weeks. Virus mRNA and antigens were detected in intestinal tissues (mucosal epithelium of the sigmoid colon) from patient 3. These findings suggest that IAV/IBV infects within the intestinal tract; thus, the human intestine may be an additional target organ for IAV/IBV infection.

Entamoeba histolytica is a protozoan parasite that affects a large proportion of the world's population and causes amoebic dysentery and extra-intestinal disease. Many individuals remain asymptomatic during colonisation; in 10% of individuals, the parasite breaks through the mucosal barrier and leads to invasive disease. An eight-month-old girl who was evaluated for hypo-albuminaemia and was diagnosed with amoebic colitis is reported. To the best of our knowledge, this is the first report of hypo-albuminaemia owing to amoebic colitis in any age group.

A 40-year-old woman had been diagnosed with Crohns disease in September 1994, but later examinations revealed a primary T-cell lymphoma of the colon. Colonoscopic and histological examination showed ulcerative lesions simulating Crohns disease involving the entire colon and the terminal ileum, and she was first diagnosed as having Crohns disease. Differential therapeutic strategies, including corticosteroid, had improved the symptoms which were dominated by abdominal pain. When she visited our institute in April 1995, she presented with bloody stool twice a day, 7kg weight loss in a period of six months and a slightly painful abdomen. Colonoscopic finding showed geographic ulceration on the entire colon, especially rectum and terminal ileum. The histologic examination of specimens from colonoscopic biopsy showed primary peripheral T-cell lymphoma of the colon. Any dense lymphocyte infiltrates seen in the biopsy specimens obtained from lesions simulating ulcerative colitis or Crohns disease should be assessed to exclude intestinal lymphoma PMID:9439161

A multi-wavelength prism coupling refractometer is utilized to measure the angular reflectance of freshly excised human intestinal tissue specimens. Based on reflectance data, the real and imaginary part of the refractive index is calculated via Fresnel analysis for three visible (blue, green, red) and two near-infrared (963 nm and 1551 nm) wavelengths. Averaged values of the complex refractive index and corresponding Cauchy dispersion fits are given for the mucosa, submucosa and serosa layers of the colorectal wall at the normal state. The refractive constants of tumorous and normal mucosa are then cross-compared for the indicative cases of one patient diagnosed with a benign polyp and three patients diagnosed with adenocarcinomas of different phenotype. Significant index contrast exists between the normal and diseased states, indicating the potential use of refractive index as a marker of colorectal dysplasia. © 2016 WILEY-VCH Verlag GmbH & Co.

Congenital hernia of the cord, also known as umbilical cord hernia, is an often misdiagnosed and under-reported entity, easily confused with a small omphalocele. It is different from postnatally diagnosed umbilical hernias and is believed to arise from persistent physiological mid-gut herniation. Its incidence is estimated to be 1 in 5000. Unlike an omphalocele, it is considered benign and is not linked with chromosomal anomalies. It has been loosely associated with intestinal anomalies, suggesting the need for a complete fetal anatomical ultrasound evaluation. We present a case of a fetal umbilical cord hernia diagnosed in a 28-year-old woman at 21 weeks gestation. The antenatal and intrapartum courses were uncomplicated. It was misdiagnosed postnatally as a small omphalocele, causing unwarranted anxiety in the parents. Increased awareness and knowledge of such an entity among health professionals is important to prevent unwarranted anxiety from misdiagnosis, and inadvertent bowel injury during cord clamping at delivery.

Necrotizing enterocolitis (NEC) remains one of the most catastrophic comorbidities associated with prematurity. In spite of extensive research, the disease remains unsolved. The aims of this paper are to present the current state of the science on the pathogenesis of NEC, summarize the clinical presentation and severity staging of the disease, and highlight the nursing assessments required for early identification of NEC and ongoing care for infants diagnosed with this gastrointestinal disease. The distributions of systemic and intestinal clinical signs that are most sensitive to nursing assessment and associated with Bell Staging Criteria are presented. This descriptive data is representative of 117 cases of NEC diagnosed in low gestational age infants (<29 weeks gestation). The data highlights the clinical signs most commonly observed in infants with NEC, and thus, provides NICU nurses an evidence-based guide for assessment and care of infants with NEC. PMID:21730907

Helicobacter pylori link to pernicious anaemia.

PubMed

Desai, H G; Gupte, P A

2007-12-01

An immunological classification of chronic gastritis based on the detection of Helicobacter pylori (H. pylori) antibody, parietal cell antibody, intrinsic factor antibody, is reported. H. pylori chronic gastritis, slowly progresses to atrophic gastritis, in the majority of patients; in a few patients, with genetic susceptibility to form intrinsic factor antibody, it progresses to pernicious anaemia. In majority of patients of pernicious anaemia, H. pylori gradually disappears from the gastric mucosa, on development of intestinal metaplasia in them. Atrophic gastritis results from H. pylori or non H. pylori. H. pylori infection is diagnosed in the presence of H. pylori in the gastric mucosal biopsy and/or H. pylori antibody (IgG) in the serum. The presence of the genetic factor (intrinsic factor antibody) is essential for the diagnosis of pernicious aneamia. Pernicious anaemia patients without intrinsic factor antibody, should be correctly diagnosed as atrophic gastritis, in view of the absence of the genetic factor (intrinsic factor antibody) in them.

Use of a novel monoclonal antibody in diagnosis of Barrett's esophagus.

Griffel, L H; Amenta, P S; Das, K M

2000-01-01

A novel monoclonal antibody (MAbDAS-1), that specifically reacts with colonic but not small intestinal epithelium, recognizes specialized columnar epithelium (SCE) in the esophagus. The frequency of its reactivity in biopsy specimens of patients with endoscopically suspected Barrett's Esophagus (BE) is examined. Fifty-two biopsy specimens of the distal esophagus from 38 patients were tested by immunoperoxidase method using MAbDAS-1. Fifty-four samples of cardia-type mucosa biopsied from the stomach were used as controls. Results were compared with histology and Alcian blue/high iron diamine (AB/HID). Of the 52 specimens, 29 had glandular epithelium and the rest had only squamous epithelium. Ten were diagnosed to have SCE by histology. All 10 samples reacted with MAbDAS-1 and with Alcian blue. Of the remaining 19 specimens, five also reacted with MAbDAS-1. None of the squamous epithelium and cardia specimens reacted with MAbDAS-1. MAbDAS-1 may detect intestinal metaplasia of the esophagus of colonic phenotype in the absence of histological evidence of SCE.

The goal of this study was to determine the prevalence of digestive helminthiasis among patients referred to the laboratory of Parasitology and mycology at Le Dantec Hospital in Dakar for examination of stool samples from 2004 to 2009. Of 1 526 direct stool examinations (Ritchie and Baerman techniques) analyzed at the laboratory of Parasitology and Mycology of Le Dantec Hospital from 2004 to 2009, 310 were positive for intestinal helminthiasis, for a prevalence of 20.3%. The main species found were: Ascaris lumbricoides, Trichuris trichiura, Strongyloides stercoralis, Tænia saginata and Tænia solium. Most patients had a single parasite (90.1%, versus 9% with two and 0.9% with three). Men are infected more often than women, accounting respectively for 58% and 42% of the infections, for a sex ratio of 1.38. Children aged 10 to 15 years had the highest prevalence of infection: 34.5%. The results show that digestive helminthiasis is endemic in Dakar, where it is necessary to implement campaigns of deworming, health education and environmental improvement.

Poliomyelitis in children can cause paralysis of shoulder girdle muscles leading to a flail shoulder. Shoulder arthrodesis is indicated as a possible treatment for these children in order to stabilize the shoulder. This retrospective study reviewed all shoulder arthrodesis surgeries owing to complications of polio performed at a major medical institution between 1981 and 1996 to assess position of fusion, radiographic evidence of fusion, complications, and patient satisfaction. A review of medical records identified 11 patients undergoing 13 shoulder arthrodesis procedures, with a mean age of 14.7 years at the time of the procedure. Internal fixation was achieved with large cancellous screws in 8 patients and a Dynamic Compression Plate (DCP) plate in 5 procedures. Average follow-up period was 41 months. Eight patients were placed into a spica cast and 5 used a sling postoperatively. Shoulder arthrodesis surgery in this cohort resulted in an average position of fusion with 42.3 degrees of abduction, 23.8 degrees of flexion, and 26.2 degrees of internal rotation. Twelve of the 13 procedures assessed for radiographic union demonstrated fusion. The most common complications were malrotation and nonunion. Of the 13 procedures, 2 underwent humeral osteotomies for malrotation, and 1 with 6.5 mm cancellous screws required revision with a DCP plate owing to nonunion. Six patients underwent hardware removal, 3 of which were specifically owing to complaints of painful hardware. At final follow-up, no patient reported pain and all expressed satisfaction with their results and improved shoulder function after repair. This study is the largest series of shoulder arthrodesis surgeries for treatment of patients with a flail shoulder from polio to date, providing a more thorough analysis of its efficacy as an indicated treatment.

Latent parasitic infections can reactivate because of immunosuppression. We conducted a prospective observational study of all human immunodeficiency virus (HIV)–infected immigrants who visited the Infectious Diseases Department of the Hospital Universitari Vall d'Hebron, Barcelona, Spain, during June 2010–May 2011. Screening of the most prevalent tropical diseases (intestinal parasitosis, Chagas disease, leishmaniasis, malaria, schistosomiasis, and strongyloidiasis) was performed according to geographic origin. A total of 190 patients were included: 141 (74.2%) from Latin America, 41 (21.6%) from sub-Saharan Africa, and 8 (4.2%) from northern Africa. Overall, 36.8% (70 of 190) of the patients had at least one positive result for any parasitic disease: 5 patients with positive Trypanosoma cruzi serology, 11 patients with positive Schistosoma mansoni serology, 35 patients with positive Strongyloides stercoralis serology, 7 patients with positive Leishmania infantum serology, intestinal parasitosis were detected in 37 patients, malaria was diagnosed in one symptomatic patient. We propose a screening and management strategy of latent parasitic infections in immigrant patients infected with HIV. PMID:23509119

Primary intestinal lymphangiectasia: Minireview

2014-01-01

Primary idiopathic intestinal lymphangiectasia is an unusual disease featured by the presence of dilated lymphatic channels which are located in the mucosa, submucosa or subserosa leading to protein loosing enteropathy.Most often affected were children and generally diagnosed before third year of life but may be rarely seen in adults too. Bilateral pitting oedema of lower limb is the main clinical manifestation mimicking the systemic disease and posing a real diagnostic dilemma to the clinicians to differentiate it from other common systemic diseases like Congestive cardiac failure, Nephrotic Syndrome, Protein Energy Malnutrition, etc. Diagnosis can be made on capsule endoscopy which can localise the lesion but unable to take biopsy samples. Thus, recently double-balloon enteroscopy and biopsy in combination can be used as an effective diagnostic tool to hit the correct diagnosis. Patients respond dramatically to diet constituting low long chain triglycerides and high protein content with supplements of medium chain triglyceride. So early diagnosis is important to prevent untoward complications related to disease or treatment for the sake of accurate pathological diagnosis. PMID:25325063

The aim of this study was to assess the diagnostic value of ultrasonography for juvenile polyps in children and their sonographic characteristics. A retrospective analysis was performed of the ultrasound findings in 27 children who were diagnosed preoperatively with juvenile polyp within the intestinal tract by ultrasonography and then confirmed by colonoscopy, laparotomy and histopathology. The ultrasonic finding common to all polyps was an isolated intraluminal nodular or massive protrusion, associated with multiple mesh-like fluid areas of different sizes. In 25 children, surrounding pedicle-like low echoes of varying lengths were seen connecting with the polyps to form "mushroom" sign. The color Doppler showed abundant blood flow signals within all polyps and pedicles in a shape of a branch or an umbrella. For seven children with an intussusception, the polyp shadow was detected in the cervical part or interior of the intussusception. Ultrasonography is, thus, considered to be a feasible method for diagnosing intestinal juvenile polyp. Copyright © 2012 World Federation for Ultrasound in Medicine & Biology.

Intestinal lymphangiectasia is a rare disease characterized by focal or diffuse dilated enteric lymphatics with impaired lymph drainage. It causes protein-losing enteropathy and may lead to gastrointestinal bleeding. Commonly, lymphangiectasia presents as whitish spots or specks. To our knowledge, small bowel bleeding resulting from polypoid intestinal lymphangiectasia has not been reported. Here, we report a rare case of active bleeding from the small bowel caused by polypoid lymphangiectasia with a review of the relevant literature. An 80-year-old woman was hospitalized for melena. Esophagogastroduodenoscopy could not identify the source of bleeding. Subsequent colonoscopy showed fresh bloody material gushing from the small bowel. An abdominal-pelvic contrast-enhanced computed tomography scan did not reveal any abnormal findings. Video capsule endoscopy showed evidence of active and recent bleeding in the ileum. To localize the bleeding site, we performed double balloon enteroscopy by the anal approach. A small, bleeding, polypoid lesion was found in the distal ileum and was successfully removed using endoscopic snare electrocautery. PMID:24363538

No Paragonimus in high-risk groups in Côte d'Ivoire, but considerable prevalence of helminths and intestinal protozoon infections

PubMed Central

2011-01-01

Background Paragonimiasis is a neglected tropical disease caused by an infection with lung flukes that is transmitted through the consumption of undercooked crabs. The disease is often confused with tuberculosis. Paragonimiasis is thought to be endemic in south-western Côte d'Ivoire. Methods Two cross-sectional surveys were carried out in the first half of 2009 in patients attending two tuberculosis centres of Abidjan. A third cross-sectional survey was conducted in May 2010 in children of two primary schools in Dabou, where crabs are frequently consumed. Patients with chronic cough provided three sputum samples plus one stool sample. Sputum samples were examined for tuberculosis with an auramine staining technique and for Paragonimus eggs using a concentration technique. Stool samples were subjected to the Ritchie technique. Schoolchildren provided a single stool sample, and samples were subjected to the Kato-Katz and an ether-concentration technique. A pre-tested questionnaire was administered to patients and schoolchildren to investigate food consumption habits. Additionally, between June 2009 and August 2010, shellfish were purchased from markets in Abidjan and Dabou and examined for metacercariae. Results No human case of paragonimiasis was diagnosed. However, trematode infections were seen in 32 of the 272 shellfish examined (11.8%). Questionnaire results revealed that crab and pig meat is well cooked before consumption. Among the 278 patients with complete data records, 62 had tuberculosis, with a higher prevalence in males than females (28.8% vs. 13.9%, χ2 = 8.79, p = 0.003). The prevalence of helminths and intestinal protozoa was 4.6% and 16.9%, respectively. In the school survey, among 166 children with complete data records, the prevalence of helminths and intestinal protozoa was 22.3% and 48.8%, respectively. Boys had significantly higher prevalences of helminths and intestinal protozoa than girls. Hookworm was the predominant helminth species and Entamoeba coli was the most common intestinal protozoon species (13.8%). Conclusions Not a single case of Paragonimus was found in two high-risk groups of Côte d'Ivoire, most likely explained by food consumption habits. However, other helminth and intestinal protozoon infections were common. PMID:21639877

To evaluate the long-term results after managing intraoperative and late-diagnosed cases of iatrogenic ureteric injury (IUI), treated endoscopically or by open surgery. Patients immediately diagnosed with IUI were managed under the same anaesthetic, while those referred late had a radiological assessment of the site of injury, and endoscopic management. Open surgical procedures were used only for the failed cases with previous diversion. In all, 98 patients who were followed had IUI after gynaecological, abdominopelvic and ureteroscopic procedures in 60.2%, 14.3% and 25.5%, respectively. The 27 patients diagnosed during surgery were managed immediately, while in the late-referred 71 patients ureteroscopic ureteric realignment with stenting was successful in 26 (36.6%). Complex open reconstruction with re-implantation or ureteric substitution, using bladder-tube or intestinal-loop procedures, was used in 27 (60%), 16 (35.5%) and two (4.5%) patients of the late group, respectively. A long-term radiological follow-up with a mean (range) of 46.6 (24.5-144) months showed recurrent obstruction in 16 (16.3%) patients managed endoscopically and reflux in six (8.3%) patients. Three renal units only (3%) were lost in the late-presenting patients. Patients managed immediately had better long-term results. More than a third of the late-diagnosed patients were successfully managed endoscopically with minimal morbidity. Open reconstruction by an experienced urologist who can perform a complex substitutional procedure was mandatory to preserve renal units in the long-term.

Hookworm infections are widely prevalent in tropical and subtropical areas, especially in low income regions. In the body, hookworms parasitize the proximal small intestine, leading to chronic intestinal hemorrhage and iron deficiency anemia. Occasionally, hookworms can cause overt gastrointestinal bleeding, but this is often ignored in heavily burdened individuals from endemic infectious areas. A total of 424 patients with overt obscure gastrointestinal bleeding were diagnosed by numerous blood tests or stool examinations as well as esophagogastroduodenoscopy, colonoscopy, capsule endoscopy or double-balloon enteroscopy. All of the patients lived in hookworm endemic areas and were not screened for hookworm infection using sensitive tests before the final diagnosis. The patients recovered after albendazole treatment, blood transfusion, and iron replacement, and none of the patients experienced recurrent bleeding in the follow-up. All the 31 patients were diagnosed with hookworm infections without other concomitant bleeding lesions, a rate of 7.3% (31/424). Seventeen out of 227 patients were diagnosed with hookworm infections in the capsule endoscopy (CE), and 14 out of 197 patients were diagnosed with hookworm infections in the double balloon enteroscopy (DBE). Hookworm infections can cause overt gastrointestinal bleeding and should be screened in patients with overt obscure gastrointestinal bleeding (OGIB) in endemic infectious areas with sensitive methods. Specifically, the examination of stool specimens is clinically warranted for most patients, and the proper examination for stool eggs relies on staff's communication.

Among patients with congenital heart disease (CHD), the coexistence of noncardiac congenital anatomic abnormalities (NC), genetic abnormalities (GA), and syndromes (S) may influence therapeutic strategies and outcomes. The appreciated prevalence of these abnormalities has risen because increased screening and improved diagnostic precision enable identification of these comorbidities in a larger fraction of neonates with CHD. We examined the contemporary prevalence and distribution of NC/GA/S across diagnostic groups among neonates undergoing cardiac operations using a large nationally representative clinical registry. The Society of Thoracic Surgeons Congenital Heart Surgery Database (STS-CHSD) was queried to identify neonates (≤30 days) who underwent index cardiac operations from 2010 to 2013. The fundamental cardiac diagnosis was used to identify 10 diagnostic groups. The prevalence of NC/GA/S was reported across each group. The cohort included 15,376 index neonatal operations from 112 centers. Overall, 18.8% (2,894 of 15,376) of operations were performed in neonates with NC/GA/S. Patients with atrioventricular septal defect (212 of 357 [59.4%]), interrupted aortic arch (248 of 567 [43.7%]), truncus arteriosus (204 of 554 [36.8%]), and tetralogy of Fallot (417 of 1,383 [30.2%]) had the highest prevalence of NC/GA/S abnormalities, whereas those with transposition of the great arteries (111 of 2,778 [4.0%]) had the lowest prevalence. The most commonly identified NC/GA/S included heterotaxy (597 of 15,376 [3.9%]), DiGeorge syndrome or 22q11 deletion (550 of 15,376 [3.6%]), Down syndrome or trisomy 21 (318 of 15, 376 [2.1%]), intestinal malrotation (220 of 15,376 [1.4%]), and Turner syndrome or 45XO (189 of 15,376 [1.2%]). The prevalence of NC/GA/S varies widely across CHD diagnostic groups. This information may be useful for patient counseling, recommendations for screening for anomalies and genetic disorders, and perioperative management.

To summarize the clinical features of different racial patients with celiac disease (CD) and analyze the disease prevalence, diagnosis and treatment in Chinese population. All the patients were diagnosed as CD and enrolled in Beijing United Family Hospital between January 2005 and July 2015.Clinical data including nationality, age, symptoms, endoscopic and pathological findings, outcome were collected and compared in patients from different countries. A total of 87 patients were enrolled including 63 Caucasians, 18 Asian patients and 6 Middle East patients.The peak age of disease onset was 40-60 years old.Patients with typical symptoms such as chronic diarrhea and weight loss only accounted for 20.7%(18/87) and 9.2%(8/87) respectively.Some patients presented with nonspecific symptoms such as abdominal pain and bloating [32.2%(28/87)], even constipation [5.7%(5/87)].13.8%(12/87) patients were previously diagnosed as irritable bowel syndrome.The incidence of abdominal pain, bloating, diarrhea and constipation between Asians and Caucasians had no statistical significance (P>0.05); but the proportions of weight loss, growth retardation, iron deficiency anemia and dermatitis herpetiformis in Asian group were significantly higher than that in Caucasian group (P<0.05). IgA type of anti-gliadin antibody (AGA), endomysium antibody (EMA) and tissue transglutaminase antibody (tTGA) were dominant autoimmune antibodies in patients with CD, which accounted for 58.6%(51/87), 44.8%(39/87) and 36.8%(32/87) respectively.The endoscopy showed that the lesion of CD was mainly located in small intestine, with reducing severity from the proximal to the distal small intestine.The lesions of duodenal bulb and descending duodenum appeared more significant in Asian group.Accordingly pathological intestinal atrophy and the degree of intraepithelial lymphocytosis were more severe in Asian patients.All 87 cases took the gluten-free diet (GFD). Eighty-one cases received serological follow up and 8 with endoscopic intestinal biopsy.The celiac disease antibodies in 47 patients turned negative from 6-9 months after GFD treatment, while 34 patients turned negative from 12-18 months after GFD.All patients reported disease remission to some extent.After 1 year GFD treatment, the pathology of endoscopic intestinal biopsy in 8 patients showed significant improvement of villous atrophy and lymphocyte infiltration. CD patients with typical clinical manifestations are not the majority.Serological celiac disease antibodies (AGA, EMA and tTGA) have a high diagnostic value.GFD treatment is effective on majority of celiac patients.Clinical manifestations, endoscopy, intestinal pathology, and response to GFD in Chinese patients are not the same as Caucasians.Clinicians need to pay attention to the differential diagnosis.

The diagnosis of intestinal lymphangiectasia (IL) has been associated with characteristic duodenal mucosal changes. However, the sensitivity and specificity of the endoscopic duodenal mucosal appearance for the diagnosis of IL are not reported. To evaluate the utility of endoscopic images of the duodenum for diagnosis of IL. Endoscopic appearance of the duodenal mucosal might predict histopathologic diagnosis of IL with a high degree of sensitivity and specificity. 51 dogs that underwent upper gastrointestinal (GI) endoscopy and endoscopic biopsies. Retrospective review of images acquired during endoscopy. Dogs were included if adequate biopsies were obtained during upper GI endoscopy and digital images were saved during the procedure. Images were assessed for the presence and severity of IL. Using histopathology as the gold standard, the sensitivity and specificity of endoscopy for diagnosing IL were calculated. Intestinal lymphangiectasia (IL) was diagnosed in 25/51 dogs. Gross endoscopic appearance of the duodenal mucosa had a sensitivity and specificity (95% confidence interval) of 68% (46%, 84%) and 42% (24%, 63%), respectively for diagnosis of IL. Endoscopic images in cases with lymphopenia, hypocholesterolemia, and hypoalbuminemia had a sensitivity of 80%. Endoscopic duodenal mucosa appearance alone lacks specificity and has only a moderate sensitivity for diagnosis of IL. Evaluation of biomarkers associated with PLE improved the sensitivity; however, poor specificity for diagnosis of IL supports the need for histopathologic confirmation.

The present study aimed to compare the diagnostic performance of different European reference laboratories in diagnosing helminths and intestinal protozoa, using an ether-concentration method applied to sodium acetate-acetic acid-formalin (SAF)-preserved faecal samples. In total, 102 stool specimens were analysed during a cross-sectional parasitological survey in urban farming communities in Côte d'Ivoire. Five SAF-preserved faecal samples were prepared from each specimen and forwarded to the participating reference laboratories, processed and examined under a microscope adhering to a standard operating procedure (SOP). Schistosoma mansoni (cumulative prevalence: 51.0%) and hookworm (cumulative prevalence: 39.2%) were the predominant helminths. There was excellent agreement (kappa > 0.8; p < 0.001) among the reference laboratories for the diagnosis of S. mansoni, hookworm, Trichuris trichiura and Ascaris lumbricoides. Moderate agreement (kappa = 0.54) was found for Hymenolepis nana, and lesser agreement was observed for other, less prevalent helminths. The predominant intestinal protozoa were Entamoeba coli (median prevalence: 67.6%), Blastocystis hominis (median prevalence: 55.9%) and Entamoeba histolytica/Entamoeba dispar (median prevalence: 47.1%). Substantial agreement among reference laboratories was found for E. coli (kappa = 0.69), but only fair or moderate agreement was found for other Entamoeba species, Giardia intestinalis and Chilomastix mesnili. There was only poor agreement for B. hominis, Isospora belli and Trichomonas intestinalis. In conclusion, although common helminths were reliably diagnosed by European reference laboratories, there was only moderate agreement between centres for pathogenic intestinal protozoa. Continued external quality assessment and the establishment of a formal network of reference laboratories is necessary to further enhance both accuracy and uniformity in parasite diagnosis.

It is difficult to clinically and endoscopically differentiate intestinal tuberculosis (ITB) and Crohns disease (CD). The aim of this study was to evaluate the usefulness of in vitro interferon-gamma (INF-gamma) assay for differential diagnosis between ITB and CD. Sixty patients for whom differential diagnosis between ITB and CD was difficult were enrolled between January 2007 and January 2009. The INF-gamma-producing T-cell response to early secreted antigenic target 6 and culture filtrate protein 10 were measured by T-SPOT.TB blood test in vitro. We evaluated the usefulness of T-SPOT.TB blood test by comparing its results with the final diagnosis. Twenty and forty patients were revealed to be positive and negative in T-SPOT.TB blood test, respectively. Of the 20 patients found to be positive, 12 patients (60%) were finally diagnosed as ITB, 6 patients as CD, and 2 patients as Behcets enterocolitis. Of the 40 patients with negative results, 38 patients (95%) were diagnosed as CD; one as Behcets enterocolitis; one as nonspecific colitis; none as ITB. The sensitivity and specificity of T-SPOT.TB blood test for ITB were 100% and 83.3%, respectively. Positive and negative predictive values of T-SPOT.TB blood test for ITB were 60.0% and 100%, respectively. When differential diagnosis between ITB and CD is difficult, T-SPOT.TB blood test may be a helpful and rapid diagnostic tool to exclude ITB. Prospective large-scaled studies are required for further evaluation of the usefulness of T-SPOT.TB blood test for differential diagnosis between ITB and CD.

Etiology of hemorrhagic gastroenteritis (HGE) syndrome in dogs is unknown and histopathologic and microbial investigations have only been performed post mortem. To identify characteristic intra vitam endoscopic and histologic mucosal lesions, as well as bacterial species, within the mucosa of dogs with HGE. Ten dogs diagnosed with HGE were included. Eleven dogs with gastroduodenoscopy and different intestinal diseases were used as controls for microbial changes. Dogs pretreated with antibiotics or diagnosed with any disease known to cause bloody diarrhea were excluded from the study. In this prospective study, gastrointestinal biopsies were collected from 10 dogs with HGE. Endoscopic and histologic changes were assessed according to WSAVA guidelines. Biopsies from the stomach, duodenum, ileum, and colon were investigated by histology and by immunohistochemistry for the presence of Clostridium spp. and parvovirus. The first duodenal biopsy taken with a sterile forceps was submitted for bacterial culture. Acute mucosal lesions were only found in the intestines, not in the stomach. Clostridium spp., identified as Clostridium perfringens in 6/9 cases, were detected on the small intestinal mucosa in all dogs with HGE, either by culture or immunohistopathology. In the control group, C. perfringens could only be cultured in one of 11 dogs. The results of this study demonstrate an apparent association between C. perfringens and the occurrence of acute hemorrhagic diarrhea. The term "HGE," which implies the involvement of the stomach, should be renamed as "acute hemorrhagic diarrhea syndrome." Copyright © 2013 by the American College of Veterinary Internal Medicine.

To analyze the presentation and timing of blunt mesenteric and intestinal trauma requiring surgical intervention. The Hadassah-Hebrew University trauma registry was scanned for patients who required surgery following blunt mesenteric and/or bowel trauma. Demographic data, mechanism of injury, time to diagnosis and pathology reports were recorded. A literature search was also performed. The majority of patients were injured in motor vehicle accidents (26/30, 86.7%). Patients were divided into three groups. Seventeen patients diagnosed within 4 h of admission were defined as the immediate group. Indication for surgery was hemodynamic instability and/or peritonitis. The most commonly injured region was the terminal ileum (10/17 patients, 59%). The second group (n = 4) had surgery within 2 weeks of injury (early group). These patients presented initially with hemodynamic instability. The operative findings were consistent with a low-flow state of the terminal ileum and cecum. The third group (n = 9) consisted of patients who were operated later than 2 weeks from the date of injury (late group). These patients presented with prolonged abdominal symptoms, chiefly partial small bowel obstruction. Operative findings were bowel strictures, most commonly of the terminal ileum (7/9 patients, 77.8%). Acceleration-deceleration abdominal injury affects the terminal ileum more commonly. We propose that the ensuing clinical picture depends on the level of energy transmitted: high-energy trauma leads to extensive mesenteric and bowel tears and is diagnosed immediately. Low-energy trauma may lead to chronic ischemia, fibrosis and stricture-formation. The right colon appears to be more vulnerable to lowflow states following blunt trauma.

Acute diarrhea is one of the most serious public health problems in developing countries because it is generally associated with unfavorable living conditions. The objective of this study was to analyze trends in hospital discharges for intestinal infectious disease in children under age 5 recorded in official public hospitals from Argentina in the 2005-2013 period. This was an ecological, time-series study based on data provided by the Health Statistics and Information Department, at a national and regional level. Specific hospital discharge rates were estimated, and seasonal behavior and trends were analyzed in relation to this event. In Argentina, 2 521 729 patients under age 5 were discharged in this period; of these, 9.0% were diagnosed with intestinal infectious disease. Children under age 1 accounted for a third of hospitalizations; two annual peaks (summer and winter) were observed in the seasonality analysis. Overall, a downward trend was observed, with a mild increase in the 2007-2009 period. Rates were up to 3 or 4 times higher in Northwest and Northeast Argentina than in the Pampa region. Hospital discharges for intestinal infectious disease in the public subsector account for approximately 10% of all discharges of children under age 5. This event shows a seasonal pattern, with a slightly downward trend over the past years in spite of its heterogeneous distribution across the different Argentine regions.

Cytomegalovirus (CMV) enteritis after allogeneic hematopoietic stem cell transplantation (allo-HSCT) is difficult to diagnose. We aimed to evaluate the sensitivity and specificity of the detection of CMV DNA in feces for predicting CMV enteritis. HSCT patients with intestinal graft-versus-host disease (GVHD) were enrolled if they met the following criteria: (i) underwent a colonoscopy and (ii) peripheral blood and feces specimens were available for CMV DNA detection within 24 h of colonoscopy. The colonoscopy histology was used as the gold standard for diagnosing CMV enteritis. Fifty-six patients underwent 58 colonoscopy examinations, and 7 were diagnosed as having CMV enteritis. Within 24 h of colonoscopy, 9 patients had detectable CMV in the feces and 19 patients had detectable CMV in the plasma, respectively. In the 7 patients with CMV enteritis, only 2 had detectable CMV in the stool, resulting in a sensitivity of 28.6%. In the 51 patients without CMV enteritis, 44 had no detectable CMV in the stool, with a specificity of 86.3%. We concluded that CMV detection in the feces was not a good predictor of CMV enteritis in patients with intestinal GVHD after allo-HSCT. © 2015 John Wiley & Sons A/S.

A one and half years male child presented with constipation with severe colicky abdominal pain, bilious vomiting & abdominal distension. He had history of recurrent bouts of constipation followed by gastroenteritis since birth for which he had taken symptomatic treatment & sometimes remained symptom free but he had no other significant history or associated condition. In laboratory investigations, barium enema study of large gut result simulates to Hirschsprung's disease but suction rectal biopsy revealed normal rectal tissue texture. So, consideration of diagnostic tools along with patient's general condition decision was taken for diagnostic laparotomy & peroperatively the child was diagnosed as a case of intestinal obstruction due to congenital colonic stenosis in the descending colon. After resection of stenotic segment and end to end anastomosis, histopathologycal examination of resected stenosed colon was done & it was finally proved as congenital stenosis in the descending colon. The post operative period of the patient was uneventful and he was discharged on 7th postoperative day & followed up upto 6 months. He had been found alright without any complain. Here we tried to high light that the congenital colonic stenosis as a rare, but might be a possible cause of partial/complete intestinal obstruction from newborn to older children in any part of the colon & that should kept in mind for avoiding diagnostic dilemma & proper management of patient.

What a practitioner needs to know about celiac disease?

PubMed

Garg, Kapil; Gupta, R K

2015-02-01

Celiac disease (CD) is an immune-mediated systemic disorder elicited by gluten and related prolamines in genetically susceptible individuals and is characterized by the presence of a variable combination of gluten-dependent clinical manifestations, CD-specific antibodies, HLA-DQ2 or HLA-DQ8 haplotypes and enteropathy. CD is triggered by wheat gluten and related prolamines in barley and rye. Worldwide, the disease affects approximately 1 % of the general population. Clinical features of CD vary considerably. Intestinal symptoms are more common in young children. In older children extra intestinal manifestations affecting almost all organs are seen. IgA tTG antibody, upper GI endoscopy with histological analysis of multiple biopsies of the duodenum and in selected cases HLA DQ2 and DQ8 positivity and endomysial antibodies (EMA) are needed for diagnosis. Currently, the only treatment for CD is a life-long gluten-free diet (GFD). Strict avoidance of wheat, rye, barley and their derivatives will result in intestinal healing and relief of symptoms for the majority of individuals with CD. The GFD is simple in principle, however, completely eliminating all foods and ingredients containing wheat, rye, barley, and most commercial oats can be very challenging. Newly diagnosed CD children should undergo testing and treatment for micronutrient deficiencies specially iron, folic acid, vitamin D, and vitamin B12. Long-term monitoring and follow up of patients with CD is necessary.

We report the first study to evaluate the intestinal mucosal microbiota of dogs with inflammatory bowel disease (IBD) and dogs with food-responsive diarrhea (FRD) before and after treatment. It was hypothesized that differences in the microbial composition exist between both disease groups and within groups pre- vs. post-treatment. Duodenal and colonic biopsies were obtained endoscopically from 24 dogs (15 FRD, 9 IBD) before and after treatment. The intestinal microbiota was evaluated by Illumina sequencing of the bacterial 16S rRNA gene. The global bacterial composition did not differ between IBD and FRD dogs, nor between treatment status. However, several bacterial taxa showed a difference in abundance. Comparing disease groups, an unclassified genus of Neisseriaceae was abundant in the duodenum in the IBD group, whereas Bilophila occurred more frequently in the duodenum and Burkholderia in the colon of FRD dogs. Comparing the microbiota pre- and post-treatment revealed Enterococcus, Corynebacterium and Proteobacteria to be enriched in the duodenum of FRD dogs pre-treatment, while Bacteroides was abundant in the colon post-treatment. In dogs with IBD, Bacteroides also reached significant abundance in the colon post-treatment. In conclusion, some differences in individual bacterial taxa were identified between IBD and FRD dogs and between treatment status. © FEMS 2017. All rights reserved.

Syndecan-1 (SDC1) is essential for maintaining normal epithelial barrier. Shedding of SDC1 ectodomain, reflected by serum soluble syndecan-1 (SSDC1) levels, is regulated by inflammation. Increased intestinal permeability plays a central role in celiac disease (CD). The association between SSDC1 levels and mucosal damage in CD has not been evaluated. To evaluate serum SSDC1 levels in children with CD and to determine its relationship with histological grading classified by modified Marsh criteria. This is a cross-sectional, pilot study, in which serum SSDC1 was analyzed by ELISA in a cohort of 49 untreated children with CD and 15 children with nonspecific abdominal pain (AP). CD was diagnosed based on positive celiac serology and small intestinal biopsy. SSDC1 levels at the time of biopsy were correlated with Marsh grading. Controls were defined by AP, negative celiac serology, normal upper endoscopy, and small intestinal biopsies. SSDC1 levels were significantly higher in CD patients compared to AP controls (116.2 ± 161 vs. 41.3 ± 17.5 ng/ml, respectively, p < 0.01). SSDC1 levels were significantly higher in patients with Marsh 3c lesion compared to AP controls (170.6 ± 201 vs. 41.3 ± 17.5 ng/ml, respectively, p < 0.05). SSDC1 concentrations displayed a significant correlation with mucosal damage defined by Marsh (r = 0.39, p < 0.05). This is the first study demonstrating elevated levels of serum SSDC1 in children with CD. Our results suggest that SSDC1 is a potentially novel marker of intestinal mucosal damage in patients with CD. Its applicability as a surrogate biomarker in CD remains to be determined.

IgG4-related disease (IgG4-RD) continues to be a diagnostic challenge and a great mimicker of malignancies. We report here a case of young man who presented with subacute intestinal obstruction with initial imaging and clinical features suggestive of carcinoma colon. 18F-FDG PET/CT showed diffuse peritoneal carcinomatosis pattern typically seen with abdominal malignancies. However, the histopathology and the raised IgG4 levels diagnosed it to be IgG4-RD. Although 18F-FDG PET/CT has typical patterns corresponding to the multisystemic involvement of IgG4-RD, the index case did not show any such findings.

Three cases of fatal septicaemia due to Plesiomonas shigelloides and one due to Edwardsiella tarda were diagnosed in newborn penguins from the Basle Zoo, Switzerland from 2003 to 2007. The affected penguins were of two different species (king penguin, Aptenodytes patagonicus, and African penguin, Spheniscus demersus) and between 2 and 10 days old at the time of death. The causative agents, E. tarda and P. shigelloides are ubiquitous bacteria which are reported to be present in the normal intestinal flora of wild and captive aquatic animals, including penguins. Their occurrence and infectious potential is discussed.

Abstract Background: Thalidomide has been successful use in patients with refractory Crohn disease (CD) in recent years. Methods: We collected the data of a postoperative CD patient who was prescribed thalidomide to induce remission and reviewed the relevant literatures. Results: A 51-year-old female was diagnosed as CD after an urgent terminal intestinal resection and presented endoscopic recurrence despite the prophylactic treatment with azathioprine (AZA). Fortunately, she achieved mucosal healing (MH) at a low dose of thalidomide for 15 months. Conclusion: Thalidomide is effective to induce MH in the postoperative CD endoscopic recurrence.

Conservative treatment of metacarpal fractures is recommended if there is no joint displacement, malrotation, displacement of over 30 degrees ad axim and shortening of over 5 mm. Surgery should be performed in open fractures and serial fractures of metacarpal bone. Early functional treatment should be carried out in stable, not displaced fractures. A cast can be used for a short period in full extended position of fingers and flexion in metacarpo-phalangeal joint in 60 - 90 degrees. Twin-tape fixation allows functional treatment after soft-tissue swelling has disappeared. Closed reduction of displaced fractures of the fifth metacarpal bone (boxer's fracture) is not successful. Cases with displacement of over 30 degrees may be treated surgically by intramedullary stabilisation.

The role of monogenic disease in children with very early onset inflammatory bowel disease.

PubMed

Kelsen, Judith R; Baldassano, Robert N

Inflammatory bowel disease (IBD) is a multifactorial disease caused by dysregulated immune responses to commensal or pathogenic intestinal microbes, resulting in chronic intestinal inflammation. Patients diagnosed with IBD occurring before the age of 5 are a unique population, known as very early onset (VEO)-IBD and can be phenotypically and genetically distinct from older-onset IBD. We aim to review the clinical presentation of children with VEO-IBD and recent discoveries that point to genomic drivers of disease that may impact our therapeutic decisions. VEO-IBD is increasing in incidence and is associated with more severe disease, aggressive progression and poor response to most conventional therapies. This article will review the advances in sequencing technology that have led to identification of novel gene variants associated with disease and potentially new targeted therapeutic options. Children with VEO-IBD may present with a different phenotype and more severe disease than older children and adults. Identification of the causal gene or pathways, these children may allow for true precision medicine with targeted therapy and improved disease course.

Intussusception is one of the important causes of intestinal obstruction in children. Hydrostatic reduction under ultrasound guidance is a popular treatment method for intussusception. In the present study, we aimed to explain the demographic characteristics of and treatment approaches in patients diagnosed with intussusception by ultrasound. Forty-one patients diagnosed with intussusception by ultrasound between August 2011 and May 2013 were retrospectively analyzed. Twenty-four of these patients who had no contraindications had been treated with ultrasound-guided hydrostatic reduction. Twenty-four of the patients were male and 17 were female, a 1.4/1 male-to-female ratio. The majority of the patients were between the ages of 6-24 months and 2-5 years. The mean age was 31.12±26.32 months (range 3-125). Patients were more frequently diagnosed in April and May. Seventeen patients who had clinical contraindications enrolled directly for surgery. In 20 of the 24 patients who underwent ultrasound-guided hydrostatic reduction, reduction was achieved. Three experienced recurrence. In two of these patients, successful reduction was achieved with the second attempt. The remaining patient was enrolled for surgery. Hydrostatic reduction was performed 26 times on these 24 patients, and in 22, success was achieved (84.6%). No procedure-related complications occurred in the patients. Ultrasound-guided hydrostatic reduction, with its high success rates and lack of radiation risk, should be the first choice therapeutic approach for children diagnosed with intussusception.

We report a case of huge colon cancer accompanied with severe hypoproteinemia. A7 4-year-old woman was referred to our hospital because of abdominal fullness. Blood examinations revealed anemia(hemoglobin 8.8 g/dL)and sever hypopro- teinemia(total protein 4.5 g/dL, albumin 1.1 g/dL). Computed tomography examination of abdomen revealed ascites and large tumor(12.5×10.5 cm)at the right side colon. By further examinations ascending colon cancer without distant metastasis was diagnosed, then we performed right hemicolectomy and primary intestinal anastomosis by open surgery. Ahuge type 1 tumor(18×12 cm)was observed in the excised specimen, which invaded to terminal ileum directly. The tumor was diagnosed moderately differentiated adenocarcinoma without lymph node metastasis(pT3N0M0, fStage II ). Postoperative course was uneventful and serum protein concentration recovered gradually to normal range. Protein leakage from the tumor cannot be proved by this case, so we can't diagnose as protein-losing enteropathy, but we strongly doubt this etiology from postoperative course in this case.

The tuberculin skin test (TST) quantifies cell-mediated immunity to tuberculosis antigens. Helminths suppress cell-mediated immunity, so we studied the effect of helminth infection and deworming on the TST in a randomized, double-blind, placebo-controlled study in an indigenous Amazon community (N = 195). Stool microscopy diagnosed helminths in 98% and co-infection with multiple species in 24% of study subjects. The TST was positive (≥ 10 mm) for 49%, and responses increased with age (P < 0.001), Bacille Calmette Guerin (BCG) vaccination (P = 0.01), and tuberculosis contact (P = 0.05). TST results had no association with helminth-egg concentrations, species, or co-infections (all P > 0.1). One month after deworming with albendazole (three daily 400-mg doses), helminths were reduced, but 63% remained infected with helminths. Albendazole did not cause a change in TST size (P = 0.8) or positivity (P = 0.9) relative to placebo. Thus, TST reactions were unaffected by albendazole therapy that partially cured intestinal helminth infections, and TST interpretation was unaffected by high-burden helminth infections and co-infection with multiple helminth species.

The occurrence of swallowed foreign bodies in the digestive system is a common problem in children with the highest incidence in children aged six months to five years. Most swallowed objects leave the human body per vias naturales while 10-20% of swallowed foreign bodies need to be removed with an endoscope. Serious and life-threatening situations are caused by the ingestion of foreign bodies in about 1% of all cases. The authors present a case of a two-year-old girl diagnosed with acute abdomen for which she was operated on. A small bowel volvulus and several intestinal fistulas were found intraoperatively. The cause of this finding was the ingestion of magnetic balls and a swallowed metal body drawn to them by magnetic force. If more than one magnetic body is ingested, it is necessary to admit the patient to hospital and to remove these foreign bodies using an endoscope. The position of the magnets which is not changing in a location inaccessible for an endoscope during 2448 hours is an indication for urgent operation.

To describe a case of tuberculosis with intestinal variant in a pregnant woman in the 17th week of pregnancy. Case report. Department of Obstetrics, Federal University of São Paulo (UNIFESP), São Paulo-SP, Brazil. Tuberculosis is a public health problem that concerns many countries in the world. It was declareda public emergency by the World Health Organization in 2005. Its presence during pregnancy brings maternal risk and fetal impairment if not treated quickly and properly. The intestinal variant is not the most common form of the disease and may be confused with inflammatory bowel diseases, especially Crohns disease. Knowledge of the specific characteristics, combined with a detailed medical history and appropriate diagnostic methods can make all the difference in gestational prognosis. We report the case of a pregnant woman who wrongly underwent treatment for inflammatory bowel disease at another service. After admission to our university hospital, fruitful diagnostic clarification was achieved and the patient was diagnosed and treated for tuberculosis. We describe the details of the investigation and, in particular, review the main characteristics in the literature for differentiating the two diseases.

Cancer risk in Barrett's oesophagus.

PubMed

Dias Pereira, António; Suspiro, Alexandra; Chaves, Paula

2007-11-01

(Table is included in full-text article.)Barrett's oesophagus results from the replacement of the normal squamous lining of the oesophagus by a columnar epithelium. It is the sole known premalignant condition for oesophageal adenocarcinoma. The annual cancer incidence of 1% in Barrett's oesophagus, calculated from published series, has been recently considered an overestimation owing to publication bias, and a 0.5% risk was proposed. The prerequisite of the presence of intestinal metaplasia for the diagnosis of Barrett's oesophagus, although widely accepted, is questioned by some authors. How adenocarcinoma incidence is influenced by requiring or not intestinal metaplasia for Barrett's oesophagus diagnosis is unknown. Most of the published studies included only (or preferentially) patients with long segments. Data on adenocarcinoma incidence in short segments (<3 cm) are very scarce, but it is believed to be lower than in long segments. The magnitude of cancer risk influences cost effectiveness of surveillance of Barrett's oesophagus. Frequently, therapeutic intervention is performed when high-grade dysplasia is diagnosed, preventing progression to adenocarcinoma. This could lead to an underestimation of cancer risk in Barrett's surveillance studies.

Intestinal lymphangiectasia is a rare disease characterized by focal or diffuse dilated enteric lymphatics with impaired lymph drainage. It causes protein-losing enteropathy and may lead to gastrointestinal bleeding. Commonly, lymphangiectasia presents as whitish spots or specks. To our knowledge, small bowel bleeding resulting from polypoid intestinal lymphangiectasia has not been reported. Here, we report a rare case of active bleeding from the small bowel caused by polypoid lymphangiectasia with a review of the relevant literature. An 80-year-old woman was hospitalized for melena. Esophagogastroduodenoscopy could not identify the source of bleeding. Subsequent colonoscopy showed fresh bloody material gushing from the small bowel. An abdominal-pelvic contrast-enhanced computed tomography scan did not reveal any abnormal findings. Video capsule endoscopy showed evidence of active and recent bleeding in the ileum. To localize the bleeding site, we performed double balloon enteroscopy by the anal approach. A small, bleeding, polypoid lesion was found in the distal ileum and was successfully removed using endoscopic snare electrocautery. © 2013 Baishideng Publishing Group Co., Limited.

The vascular type of Ehlers-Danlos syndrome is an autosomal dominant connective tissue disorder caused by a mutation in the COL3A1 gene encoding pro-alpha1 chain of type III collagen. The vascular type of Ehlers-Danlos syndrome causes severe fragility of connective tissues with arterial and intestinal ruptures and complications in surgical and radiological treatments. We present a case of a 38-year-old Italian woman who was diagnosed as having the vascular type of Ehlers-Danlos syndrome. Genetic testing, conducted by Target Enrichment approach (Agilent Technologies), identified a new mutation c.1493G>A, p.G498D in exon 21 of COL3A1 gene (heterozygous state). This mutation disrupts the normal glycine-X-Y repetitions of type III procollagen by converting glycine to aspartic acid. We report a new genetic mutation associated with the vascular type of Ehlers-Danlos syndrome. We also describe clinical and genetic findings that are important to understand the genotype/phenotype correlation in patients with the vascular type of Ehlers-Danlos syndrome.

It can exist as a silent condition and manifest in non-specific symptoms even in the absence of anemia. Even though iron deficiency anemia is the most common complication and extra-intestinal manifestation of inflammatory bowel disease, the majority of inflammatory bowel disease patients who are diagnosed with iron deficiency anemia are not treated. Areas covered: In this review, we discuss iron deficiency and iron deficiency anemia in patients with inflammatory bowel disease, and review diagnostic and therapeutic options. Expert commentary: We invite international gastroenterological societies and associations to refine the practice guidelines and include iron deficiency as a potential morbidity associated with IBD in analogy to arthritis, uveitis or any other extra intestinal manifestations. There should a more unanimous agreement among different societies on the specific diagnostic cutoff values for C-reactive protein levels, serum ferritin, and transferrin saturation in order to differentiate iron deficiency anemia from anemia of chronic disease.

The goal of this study was to determine if fecal metabolite and microbiota profiles can serve as biomarkers of human intestinal diseases, and to uncover possible gut microbe-metabolite associations. We employed proton nuclear magnetic resonance to measure fecal metabolites of healthy children and those diagnosed with diarrhea-predominant irritable bowel syndrome (IBS-D). Metabolite levels were associated with fecal microbial abundances. Using several ordination techniques, healthy and irritable bowel syndrome (IBS) samples could be distinguished based on the metabolite profiles of fecal samples, and such partitioning was congruent with the microbiota-based sample separation. Measurements of individual metabolites indicated that the intestinal environment in IBS-D was characterized by increased proteolysis, incomplete anaerobic fermentation and possible change in methane production. By correlating metabolite levels with abundances of microbial genera, a number of statistically significant metabolite-genus associations were detected in stools of healthy children. No such associations were evident for IBS children. This finding complemented the previously observed reduction in the number of microbe-microbe associations in the distal gut of the same cohort of IBS-D children.

An unprecedented pocket of intestinal schistosomiasis was discovered in the Republic of Djibouti in 1997. The first cases were diagnosed in French and Djiboutian tourists who presented initial symptoms of bilharzian infection after bathing in the fresh-water basin under Hassan Gari Bira Falls, near Randa. Seventeen cases were subsequently confirmed by detection of anti-schistosome antibodies using indirect hemagglutination (IH) and indirect immunofluorescence (IIF) and/or detection of Schistosoma mansoni eggs in the stool. Further testing was performed in 35 village inhabitants, mostly children, who had been exposed by bathing in the basin. The IH reaction was positive in 28 patients (80 p. 100) including 17 (49 p. 100) with levels greater than 1/64. In 92 p. 100 of cases, IH findings were confirmed by IIF which indicated that association with hypereosinophilia was common. Schistosoma mansoni eggs were found in stools from 7 patients (19 p. 100) who generally displayed mild hypereosinophilia. Information concerning the zone of risk was distributed and control measures were undertaken as widely as possible in Djibouti and abroad.

This study was conducted to analyze the change in intestinal flora of patients with nonalcoholic steatohepatitis and its correlation to the levels of the inflammatory cytokines interleukin-10 (IL-10) and IL-17. We selected 90 patients that were diagnosed with and treated for nonalcoholic steatohepatitis as the patient group and 80 healthy cases as the control group. We then compared the intestinal flora in the subject feces and the intestinal colonization resistance (B/E, Bifidobacterium to Enterobacter ) of both groups. Using RT-PCR, we also detected IL-10 and IL-17 mRNA levels in the peripheral blood mononuclear cells of both groups. Furthermore, we used the ELISA method to determine serum IL-10 and IL-17 levels in order to explore the correlation between IL-10, IL-17 and B/E. The number of Bifidobacterium and Lactobacillus were significantly lower in the patient group than the control group (P<0.05), while Enterobacter and Enterococcus pathogenic bacteria were significantly higher in the patient group than the control group (P<0.05). The B/E value was lower in the patient group than the control group (P<0.05). The relative expression of IL-10 and IL-17 mRNA in the patient group was significantly higher than in the control group (P<0.05). In the patient group, the serum IL-10 levels were 1.17±0.15 pg/ml, which is significantly higher than the control group serum IL-10 levels which were 0.32±0.04 pg/ml (P<0.05). The serum IL-17 levels in the patient groups were 0.96±0.11 pg/ml, which was significantly higher than the control group, which had an average of 0.28±0.01 pg/ml serum IL-17 levels (P<0.05). Pearson's correlation analysis showed that the change of B/E value of intestinal flora in the patients group were negatively correlated with serum IL-10 (r=-0.546, P<0.05), and negatively correlated with serum IL-17 (r=-0.535, P<0.05). Therefore, compared to healthy people, the expression of IL-10 and IL-17 in the peripheral blood of patients with non-alcoholic fatty liver is high. The changes in intestinal flora in patients with nonalcoholic steatohepatitis are closely related to the changes of serum IL-10 and IL-17 levels, and they are involved in the development of nonalcoholic steatohepatitis.

Entamoeba histolytica is not a common causative agent of acute appendicitis. However, amoebic appendicitis can sometimes be severe and life threatening, mainly due to a lack of awareness. Also, its frequency, clinical features, and pathogenesis remain unclear. The study subjects were HIV-1-infected individuals who presented with acute appendicitis and later underwent appendectomy at our hospital between 1996 and 2014. Formalin-fixed paraffin-embedded preserved appendix specimens were reexamined by periodic acid-Schiff (PAS) staining and PCR to identify undiagnosed amoebic appendicitis. Appendectomies were performed in 57 patients with acute appendicitis. The seroprevalence of E. histolytica was 33% (14/43) from the available stored sera. Based on the medical records, only 3 cases were clinically diagnosed as amoebic appendicitis, including 2 diagnosed at the time of appendectomy and 1 case diagnosed by rereview of the appendix after the development of postoperative complications. Retrospective analyses using PAS staining and PCR identified 3 and 3 more cases, respectively. Thus, E. histolytica infection was confirmed in 9 cases (15.8%) in the present study. Apart from a significantly higher leukocyte count in E. histolytica-positive patients than in negative patients (median, 13,760 versus 10,385 cells/μl, respectively, P = 0.02), there were no other differences in the clinical features of the PCR-positive and -negative groups. In conclusion, E. histolytica infection was confirmed in 9 (15.8%) of the appendicitis cases. However, only 3, including one diagnosed after intestinal perforation, were diagnosed before the present analyses. These results strongly suggest there is frequently a failure to detect trophozoites in routine examination, resulting in an underestimation of the incidence of amoebic appendicitis.

Exposure to microbes may be important in the development of atopic disease. Atopic diseases have been associated with specific characteristics of the intestinal microbiome. The link between intestinal microbiota and food allergy has rarely been studied, and the gold standard for diagnosing food allergy (double-blind placebo-controlled food challenge [DBPCFC]) has seldom been used. We aimed to distinguish fecal microbial signatures for food allergy in children with atopic dermatitis (AD). Pediatric patients with AD, with and without food allergy, were included in this cross-sectional observational pilot study. AD was diagnosed according to the UK Working Party criteria. Food allergy was defined as a positive DBPCFC or a convincing clinical history, in combination with sensitization to the relevant food allergen. Fecal samples were analyzed using 16S rRNA microbial analysis. Microbial signature species, discriminating between the presence and absence food allergy, were selected by elastic net regression. Eighty-two children with AD (39 girls) with a median age of 2.5 years, and 20 of whom were diagnosed with food allergy, provided fecal samples. Food allergy to peanut and cow's milk was the most common. Six bacterial species from the fecal microbiome were identified, that, when combined, distinguished between children with and without food allergy: Bifidobacterium breve, Bifidobacterium pseudocatenulatum, Bifidobacterium adolescentis, Escherichia coli, Faecalibacterium prausnitzii, and Akkermansia muciniphila (AUC 0.83, sensitivity 0.77, specificity 0.80). In this pilot study, we identified a microbial signature in children with AD that discriminates between the absence and presence of food allergy. Future studies are needed to confirm our findings. © 2018 The Author(s) Published by S. Karger AG, Basel.

Abstract The differential diagnosis of Crohn's disease (CD) and intestinal tuberculosis (ITB) remains difficult as the clinical symptoms of the 2 digestive diseases are so similar. Here we report a case where a patient was initially misdiagnosed with ITB prior to the correct CD diagnosis. The 46-year-old male patient was hospitalized elsewhere for pain in the right lower abdomen and underwent an appendectomy. The pathological diagnosis was ITB and the patient was administered antituberculosis therapy for 1 year. Afterward, the patient was readmitted to the hospital for a right lower abdominal mass. A computed tomography scan revealed intestinal gas, fistula, and abdominal mass. We performed a right hemicolectomy on the patient. Postoperatively, we diagnosed the patient with CD, based on patient history and pathological examination. According to the CD active index (CDAI), the patient was at high risk and began treatment with infliximab. The patient has remained in complete remission and made a good recovery after 8-months follow-up. We compared this case with the results of a literature review on the misdiagnosis between CD and ITB (26 previously reported cases) to determine the characteristics of misdiagnosed cases. We found that distinguishing between ITB and CD is difficult because of their varied clinical presentation, nonspecific investigative tools, and profound similarities even in pathological specimens. Although a CT scan to determine the morphology of the bowel wall is a key for correct diagnosis, each case still poses challenges for diagnosis and administrating the appropriate treatment.

In Spain, minors represent approximately 20% of the immigration flow. Many of these immigrants come from countries in the tropics and sub-tropics where intestinal parasitic infections caused by helminths and protozoa are one of the major causes of human disease. The main objective of the present work was to describe parasite infections in a group of immigrant children. A prospective evaluation was performed in 373 minors from Sub-Saharan Africa, North Africa, and Latin America. Details were collected from the medical records and physical examination. Urine, stool and peripheral blood samples were obtained for serological and routine laboratory tests. Direct and indirect parasitological tests were also performed. At least 1 parasitic disease was diagnosed in 176 (47.1%) immigrant children, while 77 (20.6%) minors were infected with two or more parasites. The number of parasites was highest in children from Sub-Saharan Africa compared with the rest of the areas of origin (p<.001), and in children from urban areas compared with those from rural areas (OR 1.27 [1.059-1.552], p=.011). The most frequent causes of multiple parasite infection were filariasis plus strongyloidiasis and filariasis plus schistosomiasis. Intestinal parasite infection was diagnosed in 38 cases (13.8%). Logistic regression analysis revealed that for each month of stay, the probability of a positive finding in the stool sample decreased by 0.02% [β=-0.020, (p=.07)]. The high infection rates of parasite diseases in immigrant children point to the need for screening protocols for certain infectious diseases in these children according to their country of origin and their length of residence in Spain.

The aim of the study was to evaluate the effectiveness of a diagnostic and therapeutic algorithm for gastroesophageal reflux disease complicated by Barrett's esophagus in 46 patients. A diagnostic and therapeutic algorithm for complicated GERD was developed. To describe the changes in the esophagus with reflux esophagitis, the Los Angeles classification was used. Intestinal metaplasia of the epithelium in the lower third of the esophagus was assessed using videoendoscopy, chromoscopy, and biopsy. Quality of life was assessed with the Gastro-Intestinal Quality of Life Index. The used methods were modeling, clinical, analytical, comparative, standardized, and questionnaire-based. Results and their discussion. Among the complications of GERD, Barrett's esophagus was diagnosed in 9 (19.6 %), peptic ulcer in the esophagus in 10 (21.7 %), peptic stricture of the esophagus in 4 (8.7 %), esophageal-gastric bleeding in 23 (50.0 %), including Malory-Weiss syndrome in 18, and erosive ulcerous bleeding in 5 people. Hiatal hernia was diagnosed in 171 (87.7 %) patients (sliding in 157 (91.8%), paraesophageal hernia in 2 (1.2%), and mixed hernia in 12 (7.0%) cases). One hundred ninety-five patients underwent laparoscopic surgery. Nissen fundoplication was conducted in 176 (90.2%) patients, Toupet fundoplication in 14 (7.2%), and Dor fundoplication in 5 (2.6%). It was established that the use of the diagnostic and treatment algorithm promoted systematization and objectification of changes in complicated GERD, contributed to early diagnosis, helped in choosing treatment, and improved quality of life. Argon coagulation and use of PPIs for 8-12 weeks before surgery led to the regeneration of the mucous membrane in the esophagus. The developed diagnostic and therapeutic algorithm facilitated systematization and objectification of changes in complicated GERD, contributed to early diagnosis, helped in choosing treatment, and improved quality of life.

Aim An increase in intestinal gas production due to small intestinal bowel overgrowth (SIBO) is a contributing factor for flatus incontinence. The aims of our study were to assess the efficacy of metronidazole in a select population of patients with flatus incontinence associated with SIBO and to compare its efficacy with that of a combination of simethicone and activated charcoal (SC; Carbosylane) in randomized experimental arms. Methods Adult patients suffering from flatus incontinence associated with SIBO diagnosed by a glucose breath test were enrolled in the study. They were given metronidazole or Carbosylane (SC) for 10 days. The reduction in the mean daily number of gas leakages reported in a 3-day diary before and at the end of the treatment was used as the primary endpoint. Results Of 52 consecutive subjects with flatus incontinence, 23 (44%) had SIBO, 16 (33%) of whom were included in and completed the study. The relative reduction in flatus incontinence episodes was significantly higher in the metronidazole than in the SC group (66.8±34.8% vs. 25±50%, P = 0.03), decreasing by more than 50% in 7 (87.5%) of the subjects in the metronidazole group compared with only 1 (12.5%) in the SC group (odds ratio 1.9, 95% confidence interval 0.9–56.9, P = 0.06). Conclusion Our results show a promising trend indicating that metronidazole might significantly improve flatus incontinence associated with SIBO and might be more successful in treating flatus incontinence than gas absorbents.

Primary intestinal lymphangiectasia (PIL) is a rare disease characterized by dilated intestinal lacteals resulting in lymph leakage into the small bowel lumen. Main clinical features include intermittent diarrhea, hypoproteinemia. Scattered case reports suggested that PIL is compatible to pregnancy, but with increased complications. A 34-year-old woman with endoscopically diagnosed PIL presented to antenatal our clinic at 10 weeks into gestation. She reported strict adherence to low-fat/high-protein diet with medium-chain triglycerides (MCTs) supplementation. She was general well except for moderate edema and hypoalbuminemia. At 33 weeks, she developed diarrhea, nausea, and vomiting, with decreased fetal movements. One week later, she had an asthma attack. Nonstress test showed frequent variable deceleration. The diagnosis of PIL was established endoscopically 8 years earlier. Hypoalbuminemia was corrected with intravenous albumin administration. She also received corticosteroid therapy to promote fetal lung maturation in anticipation to early termination of the pregnancy. A cesarean section was carried out at 34 weeks due to fetal distress. The baby girl was apparently healthy: weighing 2160 g, with an Apgar score of 9 at both 1 and 5 minutes. Symptoms dissipated rapidly after the delivery. The last follow-up visit at 15 months was unremarkable for both the mother and infant. PIL could be compatible with pregnancy, but requires strict adherence to dietary treatment, proper management of the symptoms (e.g., hypoalbuminemia), particularly during late gestation.

Neonatal small left colon syndrome (NSLCS) is considered a rare cause of neonatal intestinal obstruction, with few documented cases in the English literature. Maternal diabetes has been reported in 40% to 50% of the published cases of NSLCS. Currently, the incidence of maternal diabetes is increasing, but there has been no study to ascertain the incidence and significance of NSLCS in this population. This review aims to assess the current significance of NSLCS and its association with maternal diabetes. This was a retrospective review of 105 offspring of diabetic mothers who were admitted during the period 2004 to 2008 to our neonatal unit with special emphasis on associated NSLCS. There were 6 cases of intestinal obstruction in this group of 105 children. Five children, including a pair of twins, had classic features of NSLCS as demonstrated in the contrast enema with an abrupt transition at the splenic flexure and a narrow left colon. Conservative treatment was successful in all, negating the need for further invasive investigation. The sixth child had rectosigmoid Hirschprung disease. During the study period, there were no other cases of NSLCS in the nondiabetic population. Neonatal small left colon syndrome is the most common cause of intestinal obstruction in offspring of diabetic mothers. Neonatal small left colon syndrome can be confidently diagnosed in this population based on the classic clinical and radiologic findings. The incidence of NSLCS can be expected to increase as the incidence of maternal diabetes increases.

An 11-yr-old female cheetah (Acinonyx jubatus) was diagnosed clinically with hepatic and renal disease and euthanatized after an extended illness. Postmortem examination revealed 8-10 L of milky white fluid in the abdominal cavity and markedly dilated lymphatic vessels within the intestinal mesentery. The abdominal fluid was a chylous effusion based on the cytologic predominance of lymphocytes and macrophages and comparison of cholesterol and triglyceride levels in the fluid and in serum. Gross and histopathologic lesions in the liver were consistent with a diagnosis of venoocclusive liver disease. Chylous ascites is uncommon with human chronic liver disease and is rarely identified in animals.

Fetal bowel intrauterine perforation causes sterile inflammation of the peritoneum, known as meconium peritonitis. In some cases the perforation closes spontaneously, thus forming a meconium pseudocyst between the intestinal loops and the omentum. Meconium peritonitis, complicated by pseudocyst formation, should always be considered when a fetal abdominal mass with diverse echogenicity and hyperechogenic calcifications is observed on prenatal ultrasound. Usually, this is associated with ascites and/or polyhydramnios. The differential diagnosis necessitates exclusion of all other fetal abdominal tumors. We present a case report of meconium pseudocyst diagnosed prenatally at 32 weeks of gestation which was successfully treated by surgery after birth.

The aim of this clinical investigation was to register the frequency of endoscopically defined diseases of the upper intestinal tract in a given region (Münster and Münsterland) within the period of one year (1.8.1999-31.7.2000). Furthermore, we tried to get an impression on the quality of the upper intestinoscopies by standardised conditions which had been developed by a steering committee (endoscopists and pathologists). 20 physicians (internal specialists and gastroenterologists) examined non-preselected patients and registered all relevant findings in the upper intestinal tract. The following items were of special interest: sex, age, operations in the past, indication, way of preparation, local findings (in the upper intestinal tract), and histological assessment. The examination forms were gathered, checked for completeness and evaluated statistically. Within the given period 8859 examinations forms (45.2% male and 54% female) could be evaluated. In 16% of the patients a reflux oesophagitis was diagnosed, three times more frequently than could have been expected anamnestically regarding the patients' complaints. In 274 patients (3%) the endoscopist suspected a Barrett's oesophagus; the according histological examination confirmed this suspicion in only 125 cases. Furthermore 17 adenocarcinomas and 13 squamous cell carcinomas were found. Macroscopically 44 polyps were registered but not all of them were biopsied. In 257 patients oesophageal varices (of varying degrees) were described. Only in 30.7% of the patients a H. pylori infection (diagnosed by urease test and by histological examination) was detected in the mucosa of the stomach. In 172 patients a gastritis was macroscopically suspected but the following histological assessments were not sufficient. The prevalence of gastric ulcers was 10 %, higher than the prevalence of duodenal ulcers. Only in 50% of the patients with a duodenal ulcer a H. pylori infection could be detected. In 51 cases carcinomas (diagnosis histologically confirmed) were found with the same ratio of the diffuse type and the intestinal type. In 18 patients a carcinoma could be detected in the neighbouring area of gastric ulcers. The endoscopic findings in this investigation do not differ significantly from the results found in literature. It is important that there are more gastric ulcers than duodenal ulcers. This can be explained by the frequent use of PPIs which are prescribed additionally to NSARs and ASS. The deficits of histological diagnostics on Barett's oesophagus and gastritis were remarkable. An improvement of the endoscopic and histologic assessment quality by valid standards systematically applied should be aimed at in future. Furthermore it could be helpful to use the same nomenclature for pathologic findings to intensify the co-operation between the physicians in hospitals and the practitioners.

Watery diarrhea, hypokalemia and achlorhydria (WDHA) syndrome caused by vasoactive intestinal polypeptide (VIP) -producing tumor only rarely occurs in patients with nonpancreatic disease. A 49-year-old woman was referred for evaluation of a right adrenal tumor incidentally diagnosed by abdominal ultrasound during the investigation of chronic watery diarrhea. Laboratory findings showed hypokalemia and excessive production of VIP and catecholamines. After surgical resection of the tumor, diarrhea subsided and both electrolytes and affected hormone levels normalized. Immunohistochemical examination confirmed a diagnosis of pheochromocytoma, which contained VIP-positive ganglion-like cells. We herein present the clinical and histogenetic implications of this rare clinical entity, with literature review. PMID:17729424

To investigate the long-term follow-up of distal intestinal obstruction syndrome (DIOS) in Israeli cystic fibrosis (CF) patients. This is a multi-center, comparative, retrospective study in which we reviewed the medical records of all CF patients from three major CF centers in Israel who were treated in the period from 1980 to 2012. Patients diagnosed with DIOS were defined as the study group. The patients were diagnosed with DIOS based on their clinical presentation and typical findings on either abdominal X-ray or computerized tomography scan. For the control group, CF patients with no DIOS were matched to the patients in the study group for age, sex, and cystic fibrosis transmembrane conductance regulator (CFTR) mutations. For both groups, the collected data included age, sex, CFTR genotype, weight, height, and body mass index. Clinical data included respiratory function tests in the last five years prior to the study, respiratory function test immediately before and after the DIOS event, number of hospitalizations, sputum culture results, and CF-related conditions diagnosed according to the CF clinical practice guidelines. In the study group, data on the DIOS treatment and tendency for DIOS recurrence were also analyzed. The medical charts for a total of 350 CF patients were reviewed. Of the 350 CF patients, 26 (7.4%) were diagnosed with DIOS. The control group included 31 CF patients with no DIOS diagnosis. The mean follow-up period was 21.6 ± 8.2 years. The total of DIOS episodes in the follow-up period was 60. The distribution of DIOS episodes was as follows: 6/26 (23.1%) study patients had one episode of DIOS in their lifetime, 7/26 (26.9%) had two episodes, 7/26 (26.9%) had three episodes, and 6/26 (23.1%) had four or more episodes. Compared to the control group, DIOS patients had a significantly higher incidence of meconium ileus in the past (65.4% vs 0%, respectively, P < 0.02), more Aspergillus spp. colonization (34.6% vs 3.2%, respectively, P < 0.02), and a higher number of hospitalizations due to respiratory exacerbations (8.6 vs 6.2 mean total hospitalizations per follow-up period, respectively, P < 0.02). No other significant differences were found between the control and study groups. The conservative treatment of DIOS, which mainly includes hydration and stool softeners, was successful in 82% of the episodes. The survival rate was similar for both groups. CF patients with DIOS suffer from recurrent hospitalizations and airway pathogen acquisition. Although recurrence of DIOS is common, conservative treatment is successful in most patients.

The objective of this research was two-fold: First, to describe the normal and abnormal MR appearances of the duodenum using combined Half-Fourier Acquisition Single Shot RARE (HASTE) and gadolinium-enhanced standard and fat suppressed spoiled gradient echo (SGE) sequences. The second objective was to assess the ability of these combined sequences to detect and characterize duodenal diseases. MR examinations were performed on fifty consecutive patients with no clinical history of duodenal diseases, who were 1) imaged with HASTE and gadolinium-enhanced standard and fat suppressed SGE sequences and 2) referred to MR examination for reasons other than duodenal diseases, and were reviewed retrospectively to determine the normal MR appearances of the duodenum. A second population of patients with abnormal duodenum who were imaged with the same MR sequences were included in the second part of this study. This population was composed of 20 consecutive patients with subsequently proven duodenal abnormalities, including: malrotation (2), diverticula (4), intussusception (1), sprue (1), polyps (2), neurofibroma (1), lymphoma (1), Zollinger Ellison syndrome (1), metastatic disease (1), Crohn's disease (1), and wall thickening and duodenitis (5). Normal measurements of the duodenum are described. Abnormalities of wall thickness and duodenal masses required combined HASTE and gadolinium-enhanced SGE images to evaluate well. Abnormalities of the bowel lumen (e.g., diverticula and intussusception), and developmental variants (e.g., malrotation), were sufficiently visualized on HASTE images alone. Bowel inflammation was best shown on gadolinium-enhanced fat suppressed SGE images. HASTE and gadolinium-enhanced fat suppressed SGE sequences are complementary techniques for the demonstration of normal and abnormal duodenum. The combined use of both sequences allows evaluation of different aspects of bowel diseases; abnormalities of position, lumen, and contents are well shown on HASTE, while inflammation is best shown on gadolinium enhanced fat suppressed SGE, and wall thickening and masses are best evaluated with the combined use of both techniques.

We report a rare case of left paraduodenal hernia in patient with symptoms of abdominal subobstruction treated successful with laparoscopic management in urgent situation that have reduced the length of stay and postoperative pain. Internal hernia is only 1% of the causes of abdominal obstruction and the left paraduodenal hernia about 50% of them; it is a congenital defect that derive from malrotation and abnormal mesenteric adhesion. The modern imaging techniques help for the correct diagnosis despite difficult identification of the pathology for the various clinical presentation. The treatment of choice is the surgical intervention; the laparoscopic approach is rarely described in literature but it can reduce the morbidity, postoperative pain and the length of hospital stay.

We analyzed DNA methylation patterns and transcriptomes of primary intestinal epithelial cells (IEC) of children newly diagnosed with inflammatory bowel diseases (IBD) to learn more about pathogenesis. We obtained mucosal biopsies (N = 236) collected from terminal ileum and ascending and sigmoid colons of children (median age 13 years) newly diagnosed with IBD (43 with Crohn's disease [CD], 23 with ulcerative colitis [UC]), and 30 children without IBD (controls). Patients were recruited and managed at a hospital in the United Kingdom from 2013 through 2016. We also obtained biopsies collected at later stages from a subset of patients. IECs were purified and analyzed for genome-wide DNA methylation patterns and gene expression profiles. Adjacent microbiota were isolated from biopsies and analyzed by 16S gene sequencing. We generated intestinal organoid cultures from a subset of samples and genome-wide DNA methylation analysis was performed. We found gut segment-specific differences in DNA methylation and transcription profiles of IECs from children with IBD vs controls; some were independent of mucosal inflammation. Changes in gut microbiota between IBD and control groups were not as large and were difficult to assess because of large amounts of intra-individual variation. Only IECs from patients with CD had changes in DNA methylation and transcription patterns in terminal ileum epithelium, compared with controls. Colon epithelium from patients with CD and from patients with ulcerative colitis had distinct changes in DNA methylation and transcription patterns, compared with controls. In IECs from patients with IBD, changes in DNA methylation, compared with controls, were stable over time and were partially retained in ex-vivo organoid cultures. Statistical analyses of epithelial cell profiles allowed us to distinguish children with CD or UC from controls; profiles correlated with disease outcome parameters, such as the requirement for treatment with biologic agents. We identified specific changes in DNA methylation and transcriptome patterns in IECs from pediatric patients with IBD compared with controls. These data indicate that IECs undergo changes during IBD development and could be involved in pathogenesis. Further analyses of primary IECs from patients with IBD could improve our understanding of the large variations in disease progression and outcomes. Copyright © 2018 AGA Institute.

Knowledge regarding the health-related quality of life (HRQoL) of children with celiac disease remains limited and inconclusive. We investigated the HRQoL of three groups of 12-year-olds with: i) undetected celiac disease ii) clinically diagnosed celiac disease, and iii) without celiac disease. A school-based cross-sectional multicenter screening study invited 18 325 children, whereof 68% consented to participate. Participants provided a blood sample, which was later analyzed for anti-tissue-tranglutaminase antibodies, and alongside filled in a questionnaire. When anti-tissue-tranglutaminase antibodies were elevated, a small intestinal biopsy verified the screening-detected celiac disease diagnosis. Self-reported HRQoL was measured using Kidscreen, a generic 52 items instrument with proven reliability and validity. Scores were linearly transformed into a 0-100 scale with higher values indicating better HRQoL. Mean values with standard deviations (mean ± SD) were compared, and uni- and multivariate logistic regression models tested the odds of a low HRQoL among children with undetected or diagnosed celiac disease, respectively. Children with undetected celiac disease (n = 238) reported similar HRQoL as children without celiac disease (n = 12 037) (83.0 ± 11.0 vs. 82.5 ± 11.3, P = 0.51), and also similar HRQoL (82.2 ± 12.2, P = 0.28) to that of children with diagnosed celiac disease (n = 90), of whom 92% were adherent to treatment. Having undetected celiac disease did not increase the odds of low overall HRQoL, independent of sex, area of residence, study year and occurrence of gastrointestinal symptoms (adjusted odds ratio 0.77, 95% CI 0.54-1.10). Comparable results were seen for diagnosed celiac disease cases (adjusted odds ratio 1.11, 95% CI 0.67-1.85). Children with undetected celiac disease reported comparable HRQoL as their peers with diagnosed celiac disease, and those without celiac disease, when reporting prior to receiving the diagnosis through screening. Thus, children with celiac disease, both untreated and diagnosed, perceive their HRQoL as unimpaired by their disease.

A lifelong gluten-free diet (GFD) is regarded as the only proven and accepted therapy for coeliac disease (CD). However, even patients who strictly follow a GFD often suffer from intestinal symptoms and malabsorption. Selective modulation of intestinal microbiota with prebiotics could remedy various symptoms associated with CD. The use of prebiotics in the treatment of intestinal diseases remains insufficiently investigated. To our knowledge, this study makes the first attempt to evaluate the effect of prebiotic supplementation on gastrointestinal symptoms and nutritional status of children with CD. We hypothesized that adherence to a GFD supplemented with oligofructose-enriched inulin (Synergy 1) would deliver health benefits to children suffering from CD without any side effects, and that it would alleviate intestinal inflammation, restore and stabilize gut microbial balance and reverse nutritional deficiencies through enhanced absorption of vitamins and minerals. A randomized, placebo-controlled clinical trial was designed to assess the impact of the Synergy 1 on paediatric CD patients following a GFD. We randomized 34 children diagnosed with CD into an intervention group receiving 10 g of the Synergy 1 supplement daily and a placebo group (receiving maltodextrin) during a 12-week nutritional intervention. Selected biochemical parameters, nutritional status and the characteristics of faecal bacteria will be determined in samples collected before and after the intervention. Analysis of vitamins and amino acids concentration in biological fluids will allow to assess the dietary intake of crucial nutrients. The compliance to a GFD will be confirmed by a Food Frequency Questionnaire (FFQ-6) and the analysis of serum anti-tissue transglutaminase and faecal gluten immunogenic peptides (GIP). The identification of the beneficial effects of the Synergy 1 supplement on children with CD could have important implications for nutritional recommendations for CD patients and for alleviating the harmful effects of the disease.

Congenital portosystemic shunt (CEPS) is a rare condition that was first reported by John Abernethy in 1793. Two types of CEPS are described: type I (side to end anastomosis) or congenital absence of the portal vein, and type II (side to side anastomosis) with portal vein supply partially conserved. Type I CEPS is usually seen in girls and associates multiple malformations as polysplenia, malrotation, and cardiac anomalies. Type II is even rarer with no sex preference and no malformations associated. Hepatic encephalopathy is a common complication of both types in adulthood. Liver transplantation is the only effective treatment for symptomatic type I CEPS. A therapeutic approach for type II could be surgical closure of the shunt. To analyse our experience in diagnosis and management of portosystemic shunts. We report 4 cases of CEPS (3 type I and 1 type II) diagnosed between January-1997 and March-2005 in our department. We present 4 patients with ages at diagnosis ranging from 0 to 28 months, 3 type I CEPS (2 boys and 1 girl) and 1 boy type II. The type I girl was prenatally diagnosed at 12 weeks of gestation. Initial clinical signs in type 1 boys were splenomegaly and hypersplenism, both with normal pondo-statural growth. No polysplenia or cardiac anomalies were assessed. One of them presented mild developmental delay, dismorphic features and facial telangiectasias. He had normal coagulation tests with chronic hepatic dysfunction (high transaminases) and regenerative nodular lesions were seen by imaging techniques. The other type I patient had hypoprothrombinemia, tendency to capillary bleeding (haematomas and epistaxis) with preserved liver function. Both patients have developed mild portal hypertension and present steatosis signs at liver biopsy. The type I girl presents a 21 trisomy and associates a cardiac anomaly (interauricular communication). Her hepatic function test are normal but liver calcifications can be seen by ultrasound. Type II child associates hypospadias but he has no clinical sigh or symptom related to the shunt. In our three cases diagnosis was suggested by conventional and Doppler ultrasound and confirmed by angio-resonance imaging. All our patients are included in a meticulous clinical and radiological follow-up with no need of surgical treatment for the shunt until now. Although diagnosis of these malformations could be casual we have to think about CEPS in children presenting unspecific liver disease. Magnetic angio-resonance imaging is actually the best diagnosis methods for CEPS. These patients have a high risk for developing hepatic encephalopathy and portal hypertension, so a careful follow-up is required although surgery is not usually needed until adulthood.

Histological examination of duodenal biopsies is the gold standard for assessing intestinal damage in celiac disease (CD). A noninvasive marker of disease status is necessary, because obtaining duodenal biopsies is invasive and not suitable for routine monitoring of CD patients. As the small intestine is a major site of cytochrome P450 3A4 (CYP3A4) activity and also the location of the celiac lesion, we investigated whether patients with active CD display abnormal pharmacokinetics of an orally administered CYP3A4 substrate, simvastatin (SV), which could potentially be used for noninvasive assessment of their small intestinal health. Preclinical experiments were performed in CYP3A4-humanized mice to examine the feasibility of the test. Subsequently, a clinical trial was undertaken with 11 healthy volunteers, 18 newly diagnosed patients with CD, and 25 celiac patients who had followed a gluten-free diet (GFD) for more than 1 year. The maximum concentration (Cmax) of orally administered SV plus its major non-CYP3A4-derived metabolite SV acid (SV equivalent (SVeq)) was measured, and compared with clinical, histological, and serological parameters. In CYP3A4-humanized mice, a marked decrease in SV metabolism was observed in response to enteropathy. In the clinical setting, untreated celiac patients displayed a significantly higher SVeq Cmax (46±24 nM) compared with treated patients (21±16 nM, P<0.001) or healthy subjects (19±11 nM, P<0.005). SVeq Cmax correctly predicted the diagnosis in 16/18 untreated celiac patients, and also the recovery status of all follow-up patients that exhibited normal or near-normal biopsies (Marsh 0-2). All patients with abnormal SVeq Cmax showed a reduction in the value after 1 year of following a GFD. SVeq Cmax is a promising noninvasive marker for assessment of small intestinal health. Further studies are warranted to establish its clinical utility for assessing gut status of patients with CD.

Necrotizing enterocolitis (NEC) is an inflammatory disease of the newborn bowel, primarily affecting premature infants. Early intestinal colonization has been implicated in the pathogenesis of NEC. The objective of this prospective case-control study was to evaluate differences in the intestinal microbiota between infants who developed NEC and unaffected controls prior to disease onset. We conducted longitudinal analysis of the 16S rRNA genes of 312 samples obtained from 12 NEC cases and 26 age-matched controls with a median frequency of 7 samples per subject and median sampling interval of 3 days. We found that the microbiome undergoes dynamic development during the first two months of life with day of life being the major factor contributing to the colonization process. Depending on when the infant was diagnosed with NEC (i.e. early vs. late onset), the pattern of microbial progression was different for cases and controls. The difference in the microbiota was most overt in early onset NEC cases and controls. In proximity to NEC onset, the abundances of Clostridium sensu stricto from Clostridia class were significantly higher in early onset NEC subjects comparing to controls. In late onset NEC, Escherichia/Shigella among Gammaproteobacteria, showed an increasing pattern prior to disease onset, and was significantly higher in cases than controls six days before NEC onset. Cronobacter from Gammaproteobacteria was also significantly higher in late onset NEC cases than controls 1-3 days prior to NEC onset. Thus, the specific infectious agent associated with NEC may vary by the age of infant at disease onset. We found that intravenously administered antibiotics may have an impact on the microbial diversity present in fecal material. Longitudinal analysis at multiple time points was an important strategy utilized in this study, allowing us to appreciate the dynamics of the premature infant intestinal microbiome while approaching NEC at various points.

It is known that infections caused by intestinal protozoa and helminths affect over 3.5 million people worldwide. In this case report, a patient with complaints of stomach ache for a long time who received thermal treatment is presented. During this thermal treatment, diarrhoea occurred and multiparasitism was diagnosed with two helminths; pseudoparasitism and multiprotozoa, simultaneously. Stool samples were collected from the patient on three consecutive days and one day after the treatment. All of the samples were prepared with formalin-ether sedimentation techniques after macroscopic and direct microscopic investigation. Cellophane-tape method for Enterobius vermicularis and Taenia spp. and Erlich-Ziehl-Neelsen staining method for coccidian parasites were used. At least four preparations were performed for each sample and serum physiologic, lugol' solution and trichrome stain were used for microscopic investigations.The motile segment she brought was investigated microscopically with Indian ink and identified as Taenia saginata. Under direct microscopy, Blastocystis hominis, Endolimax nana and Fasciola hepatica were seen. By formalin-ether sedimentation techniques, Ascaris lumbricoides, Fasciola hepatica, Blastocystis hominis, Endolimax nana and Entamoeba coli were identified. In recent years, intestinal parasitism is rarely seen in our city; therefore, multiparasitism in an adult and immunocompetent patient is interesting.

Intestinal parasites in Mexico are an endemic problem. A study was conducted in children, teenagers and adults in a rural community in Colima, Mexico to examine the prevalence and intensity of Ascaris lumbricoides infection and to evaluate the parasitological and clinical efficacy of nitazoxanide (NTZ). Two hundred and eighty children, teenagers and adults participated in this study. Parasitological diagnosis from faeces was confirmed by three consecutive stool samples using the floatation concentration Faust method. Egg counts were performed as described by the Kato-Katz technique before and after treatment. A questionnaire was systematically applied to obtain information about socio-economic status and hygienic habits. One hundred and six participants (38%) were diagnosed as harbouring intestinal parasites, and 86 of them (81%) were infected with A. lumbricoides. All patients with ascariasis infections underwent a complete physical examination before and after NTZ treatment. NTZ resolved 88% of the ascariasis cases, with a 89% clinical efficacy, and there was a 97.5% reduction in the levels of morbidity. The most intense infections for A. lumbricoides were found in housewives, and statistically significant associations were found between ascariasis and the absence of drainage and living in houses with dirt floors.

Enterobiasis (oxyuriasis) is a common infection in human caused by  Enterobius vermicularis  ( E. vermicularis ), a human intestinal helminth. Because of the easy way of its transmission among people, it has an extremely high prevalence in overcrowded conditions, such as nurseries and primary schools. Oxyuriasis's symptoms are extremely diverse in children, ranging from nausea, diarrhea, insomnia, irritability, recurrent cellulitis, loss of appetite, nightmares and endometritis. Here we report a curious case of oxyuriasis in the settings of a refugee camp in Greece. The patient was a 10-year old Syrian female, who presented with unusual and vague symptoms like insomnia and irritability. Given the violent background of the Syrian warzone that the patient had escaped, she was firstly diagnosed with post traumatic stress disorder (PTSD) before eventually getting correctly diagnosed with enterobiasis. This infection is the first documented case of enterobiasis in the settings of a refugee camp and can highlight the unsanitary living conditions that refugees have to endure in those camps.

Histological gastritis is associated with gastric cancer, but its diagnosis requires biopsy. Many classifications of endoscopic gastritis are available, but not all are useful for risk stratification of gastric cancer. The Kyoto Classification of Gastritis was proposed at the 85th Congress of the Japan Gastroenterological Endoscopy Society. This cross-sectional study evaluated the usefulness of the Kyoto Classification of Gastritis for risk stratification of gastric cancer. From August 2013 to September 2014, esophagogastroduodenoscopy was performed and the gastric findings evaluated according to the Kyoto Classification of Gastritis in a total of 4062 patients. The following five endoscopic findings were selected based on previous reports: atrophy, intestinal metaplasia, enlarged folds, nodularity, and diffuse redness. A total of 3392 patients (1746 [51%] men and 1646 [49%] women) were analyzed. Among them, 107 gastric cancers were diagnosed. Atrophy was found in 2585 (78%) and intestinal metaplasia in 924 (27%). Enlarged folds, nodularity, and diffuse redness were found in 197 (5.8%), 22 (0.6%), and 573 (17%), respectively. In univariate analyses, the severity of atrophy, intestinal metaplasia, diffuse redness, age, and male sex were associated with gastric cancer. In a multivariate analysis, atrophy and male sex were found to be independent risk factors. Younger age and severe atrophy were determined to be associated with diffuse-type gastric cancer. Endoscopic detection of atrophy was associated with the risk of gastric cancer. Thus, patients with severe atrophy should be examined carefully and may require intensive follow-up. © 2017 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

Aim: The aim was to investigate breath test outcomes in patients with suspected SIBO and indicative symptoms of SIBO, diagnosed by breath testing. Background: Breath testing is used to detect small intestinal bacterial overgrowth (SIBO) by measuring hydrogen and methane produced by intestinal bacteria. Methods: This retrospective cross sectional study included 311 patients with gastrointestinal symptoms who underwent the breath test for evaluation of SIBO at Celiac Disease Center at Columbia University, New York, in 2014-2015. The patients were divided into two groups based on the physician’s choice: lactulose breath test group (72%) and glucose breath test group (28%). Among them, 38% had a history of celiac disease or non-celiac gluten sensitivity. Results: In total, 46% had a positive breath test: 18% were positive for methane, 24 % positive for hydrogen and 4% positive for both gases (p=0.014). Also, 50% had a positive lactulose breath result and 37% had a positive glucose breath result (p=0.036). The most common symptom for performing the breath test was bloating and the only clinical symptom that significantly showed a positive glucose breath test was increased gas (p=0.028). Conclusion: Lactulose breath test was more often positive than glucose breath test. Positivity for hydrogen was more common than methane. Bloating was the most frequently perceived symptom of the patients undergoing the breath test but the only statistically significant clinical symptom for a positive glucose breath test was increased gas. Furthermore, the results showed that there was no significant association between positive breath test result and gender, age, non-celiac gluten sensitivity or celiac disease. PMID:29118931

Anaemia can be considered the most common extra-intestinal manifestation in inflammatory bowel disease. Nevertheless, anaemia is often under-diagnosed and under-treated both in adults and children with inflammatory bowel disease. Herein, we report the consensus statements on the management of anaemia in inflammatory bowel disease developed by the Portuguese Working Group on Inflammatory Bowel Disease (known as Grupo de Estudo da Doença Inflamatória Intestinal - GEDII) to aid clinicians in daily management of inflammatory bowel disease patients. A comprehensive literature review was conducted in order to prepare consensus statements on the following topics: (1) prevalence and diagnosis of anaemia in inflammatory bowel disease, (2) iron supplementation for the prevention of anaemia in inflammatory bowel disease and (3) treatment of anaemia in inflammatory bowel disease. The final statements for each topic were discussed at a consensus meeting and rated according to the Oxford Centre for Evidence-Based Medicine 2011 Levels of Evidence. It was concluded that anaemia has a high incidence and prevalence in inflammatory bowel disease, particularly in those with active disease and hospitalised. Patients with anaemia had decreased quality of life and frequently complained of fatigue. Absolute indications for intravenous therapy should be considered: (1) moderate to severe anaemia (haemoglobin < 10.5 g/dL) or clearly symptomatic anaemia; (2) previous intolerance to oral iron supplements; (3) inappropriate response to oral iron; (4) active severe intestinal disease; (5) need for a quick therapeutic response (e.g. surgery in the short term); (6) concomitant therapy with erythropoiesis-stimulating agent; and (7) patient's preference.

Refeeding syndrome (RFS) has been well described but is also a frequently forgotten and undiagnosed complication in clinical practice, which, if untreated, may lead to death. Patients who are more prone to developing RFS are those with at least one of the following conditions: BMI <16 kg/m2, a recent unintentional weight loss >15%, very little nutritional intake for >10 days, and/or low plasma concentrations of potassium, phosphate or magnesium before feeding; and those with at least two of the following conditions: BMI <18.5 kg/m2, a recent weight loss >10%, very little nutritional intake for >5 day, and/or a history of alcohol abuse or drug use, including insulin, chemotherapy or diuretics. We report here a patient who, after undergoing intestinal resection (short gut syndrome), presented diarrhoea, weight loss and protein–energy malnutrition. After nutritional assessment, the nutritional support team decided to feed the patient by the parenteral route. After 16 h of parenteral nutrition, the patient developed supraventricular tachycardia, hypomagnesaemia and hypocalcaemia, and RFS was diagnosed and managed. After intestinal adaptation, the patient is currently able to maintain his nutritional status with nutrition therapy by the oral route. PMID:21686764

After reduction of the incarceration during surgery for incarcerated hernia, intestinal blood flow (IBF) and the need for bowel resection must be evaluated. We report the case of a patient with incarcerated umbilical hernia in whom the bowel was preserved after evaluating IBF using indocyanine green (ICG) fluorescence. A woman in her 40s with a chief complaint of abdominal pain visited our hospital, was diagnosed with incarcerated umbilical hernia and underwent surgery. Laparotomy was performed to reduce bowel incarceration. After reducing the incarceration, IBF was observed using ICG fluorescence detected using a brightfield full-color fluorescence camera. The small bowel that had been incarcerated showed deep-red discoloration on gross evaluation, but intravenous injection of ICG revealed uniform fluorescence of the mesentery and bowel wall. This indicated an absence of irreversible ischemic changes of the bowel, so no resection was performed. The patient showed a good postoperative course, including resumption of eating on day 4 and discharge on day 11. In surgery for incarcerated hernia, ICG fluorescence may offer a useful method to evaluate IBF after reducing the incarceration. This case implied that PINPOINT could be used in open conventional surgery.

To measure the tissue sulfomucin and sialomucin content of the colon mucosa without fecal flow, subjected to intervention with curcumin, and the influence of the concentration used and the intervention time. Thirty-six rats were subjected to proximal right colostomy and distal mucous fistula. They were divided into two groups according to whether sacrifice was performed two or four weeks after the intervention. Each group was divided into three subgroups according to the enema applied daily: saline alone; curcumin at 50 mg/kg/day or curcumin at 200 mg/kg/day. Acid mucins were diagnosed using the Alcian blue technique. The mucin content was quantified by means of computer-assisted image analysis. The significance level of 5% was used throughout (p < 0.05). There were dose-related increases in the quantities of sulfomucins in the animals subjected to interventions with curcumin, both after two weeks (p < 0.00001) and after four weeks (p < 0.00001). There were increases in sialomucin quantity that were concentration-related (p < 0.00001) and time-related (p < 0.00001). Curcumin enemas increase the quantity of acid mucins in the intestinal flow in the excluded colon, with dose and time dependency.

Chronic gastritis is one of the most common findings at upper endoscopy in the general population, and chronic atrophic gastritis is epidemiologically associated with the occurrence of gastric cancer. However, the current status of diagnosis and treatment of chronic gastritis in China is unclear. A multi-center national study was performed; all patients who underwent diagnostic upper endoscopy for evaluation of gastrointestinal symptoms from 33 centers were enrolled. Data including sex, age, symptoms and endoscopic findings were prospectively recorded. Totally 8892 patients were included. At endoscopy, 4389, 3760 and 1573 patients were diagnosed to have superficial gastritis, erosive gastritis, and atrophic gastritis, respectively. After pathologic examination, it is found that atrophic gastritis, intestinal metaplasia and dysplasia were prevalent, which accounted for 25.8%, 23.6% and 7.3% of this patient population. Endoscopic features were useful for predicting pathologic atrophy (PLR = 4.78), but it was not useful for predicting erosive gastritis. Mucosal-protective agents and PPI were most commonly used medications for chronic gastritis. The present study suggests non-atrophic gastritis is the most common endoscopic finding in Chinese patients with upper GI symptoms. Precancerous lesions, including atrophy, intestinal metaplasia and dysplasia are prevalent in Chinese patients with chronic gastritis, and endoscopic features are useful for predicting pathologic atrophy.

Neonatal leukemia is a rare disease with an estimated prevalence of about one to five in a million neonates. The majority being acute myeloid leukemia (AML), neonatal leukemia can present with a variety of symptoms including hyperleucocytosis, cytopenia, hepatosplenomegaly, and skin infiltrates. Chromosomal rearrangements including mixed lineage leukemia (MLL) translocations are common in neonatal AML. A female neonate born at 34 weeks gestation presented with cardiorespiratory failure, hepatosplenomegaly, pancytopenia, and coagulopathy. She required intensive care treatment including mechanical ventilation, high-dose catecholamine therapy, and multiple transfusions. Small intestinal biopsy obtained during laparotomy for meconium ileus revealed an infiltrate by an undifferentiated monoblastic, MLL-rearranged leukemia. No other manifestations of leukemia could be detected. After spontaneous clinical remission, lasting 5 months without any specific treatment, the patient presented with leukemia cutis and full-blown monoblastic leukemia. MLL-AF10-rearranged AML could be re-diagnosed and successfully treated with chemotherapy and hematopoietic stem cell transplantation. Our patient exhibited a unique manifestation of neonatal MLL-AF10 rearranged AML with cardiorespiratory failure and intestinal infiltration. It highlights the importance of leukemia in the differential diagnosis of neonatal distress, congenital hematological abnormalities, and skin lesions.

Aerophagia is a functional gastrointestinal disorder characterised by repetitive air swallowing, abdominal distension, belching, and flatulence. In severe cases, it can lead to pneumoperitonium, volvulus of the colon, and intestinal perforation. Little is known about the epidemiology and clinical profile of affected children. The main objective of the present study was to assess the epidemiology of aerophagia in 10- to 16-year-olds in Sri Lanka. A school-based cross-sectional survey was conducted in 8 randomly selected schools in 4 randomly selected provinces in Sri Lanka. Data were collected using a pretested, self-administered questionnaire, which was distributed in an examination setting and collected on the same day. Trained research assistants were present during completion of the questionnaire, for any required clarification. Aerophagia was diagnosed using the Rome III criteria. In the present study, aerophagia was seen in 163 (7.5%) of the 2163 children evaluated. The prevalence was higher in older children (10.5% in 15-year-olds) and no sex difference was observed (boys 8.2% vs girls 6.8%, P>0.05). Intestinal-related (abdominal pain, nausea, and anorexia) and extraintestinal symptoms (headache, limb pain, sleeping difficulty, photophobia, and lightheadedness) were more prevalent among affected children (P<0.05). A higher percentage of affected children were found to be exposed to stressful events when compared with controls (P<0.05). The present study highlights the high prevalence of aerophagia among Sri Lankan children and adolescents. This condition is more common in those exposed to emotional stress. Intestinal-related symptoms and extraintestinal somatic symptoms are frequently seen in affected children.

Inflammatory bowel disease (IBD) is a common disorder of ferrets (Mustela putorius furo) that may progress to lymphoma. Although routine histology is used to distinguish between these diseases, misclassifications may occur. Immunohistochemistry (IHC) is commonly used to distinguish between IBD and lymphoma in small animals. The objective of our study was to determine the agreement in the diagnosis reached solely using hematoxylin and eosin (HE)-stained, full-thickness sections versus using a combination of HE and IHC. Enteric sections from 44 ferrets previously diagnosed with IBD or intestinal lymphoma and 3 control ferrets were analyzed by pathologists with expertise in ferrets. A pathologist blinded to the original diagnosis assessed the same HE-stained sections. Analysis was then repeated using HE sections in parallel with sections stained using antibodies against CD3 and CD79a. No significant difference was found between the original HE diagnosis and the HE diagnosis reached by the blinded pathologist (p = 0.91) or between the blinded pathologist's HE versus HE with IHC diagnosis (p = 0.16). In the 2 cases where disagreement was present, IHC was pivotal in reaching a final diagnosis. There was no significant age (p = 0.29) difference between diagnoses; however, significantly more male ferrets were affected with IBD than females (p = 0.004). Immunophenotype of the lymphoma was not correlated with predilection for location in the intestinal wall (p = 0.44). Results suggest that although IHC is not necessary to distinguish IBD from intestinal lymphoma in ferrets, it can be useful a definitive diagnosis in cases of severe IBD. © 2016 The Author(s).

Primary chronic intestinal pseudo-obstruction (CIPO) is a rare, potentially life-threatening disorder characterized by severely impaired gastrointestinal motility. The objective of this study was to examine the contribution of ACTG2, LMOD1, MYH11, and MYLK mutations in an Australasian cohort of patients with a diagnosis of primary CIPO associated with visceral myopathy. Pediatric and adult patients with primary CIPO and suspected visceral myopathy were recruited from across Australia and New Zealand. Sanger sequencing of the genes encoding enteric gamma-actin (ACTG2) and smooth muscle leiomodin (LMOD1) was performed on DNA from patients, and their relatives, where available. MYH11 and MYLK were screened by next-generation sequencing. We identified heterozygous missense variants in ACTG2 in 7 of 17 families (~41%) diagnosed with CIPO and its associated conditions. We also identified a previously unpublished missense mutation (c.443C>T, p.Arg148Leu) in one family. One case presented with megacystis-microcolon-intestinal hypoperistalsis syndrome in utero with subsequent termination of pregnancy at 28 weeks' gestation. All of the substitutions identified occurred at arginine residues. No likely pathogenic variants in LMOD1, MYH11, or MYLK were identified within our cohort. ACTG2 mutations represent a significant underlying cause of primary CIPO with visceral myopathy and associated phenotypes in Australasian patients. Thus, ACTG2 sequencing should be considered in cases presenting with hypoperistalsis phenotypes with suspected visceral myopathy. It is likely that variants in other genes encoding enteric smooth muscle contractile proteins will contribute further to the genetic heterogeneity of hypoperistalsis phenotypes. © 2018 John Wiley & Sons Ltd.

To establish the clinical course of ulcerative colitis (UC) in the Malaysian population, comparing the three major ethnic groups: Malay, Chinese and Indian. Patients who were diagnosed with UC from seven major medical referral centers in Malaysia were recruited. Their baseline characteristics, and the extent of the disease, its clinical course and complications were recorded. A total of 118 patients was included. The extent of disease was as follows: proctitis alone in 22 (18.6%), sigmoid colon in 23 (19.5%), descending colon in 16 (13.6%), transverse colon in 11 (9.3%), ascending colon and pancolitis 46 (39%). Most patients had chronic intermittent disease. Extra-intestinal complications were seen in 27 (22.9%) patients and fulminant colitis was seen in four (3.4%). None developed colorectal cancer. The overall cumulative colectomy rates at 1, 5 and 10 years were 3.4% (CI: 0.9-8.5), 5.9% (CI: 1.9-13.2) and 15.6% (CI: 6.5-29.4), respectively. There was a higher prevalence of extra-intestinal manifestations and a trend towards more extensive disease among Indian patients. However, no significant differences were seen in the age of onset, the severity of disease (fulminant colitis, refractory disease) and the colectomy rate. As in developed countries, most of our patients have a remitting and relapsing pattern of disease but the clinical course appears to be milder, with lower rates of colectomies. There are differences in clinical presentation among the three major ethnic groups, with Indians having a higher prevalence of extra-intestinal manifestations and a trend towards more extensive disease.

Impaired immune regulation has been suggested as an underlying mechanism of inflammatory bowel disease. Indoleamine 2,3-dioxygenase (IDO) and regulatory T cells expressing FOXP3 are crucial elements of immune regulation. Conversion of FOXP3- lymphocytes to Tregs is one of the functions of IDO. The aim of this study was to evaluate the number of cells expressing FOXP3 and IDO in the lamina propria of intestinal mucosa and to evaluate correlations between these parameters and disease activity. Sixty-six children newly diagnosed with inflammatory bowel disease (41 patients with ulcerative colitis and 25 patients with Crohn’s disease) were included in the study. Clinical activity of the disease was assessed by the Pediatric Ulcerative Colitis Activity Index and the Pediatric Crohn’s Disease Activity Index. Histopathological activity was scored according to the system described by Geboes. The infiltration of FOXP3+ and IDO+ cells was evaluated by immunohistochemistry. Sixteen patients with a diagnosis of irritable bowel syndrome (IBS) served as a control group. Lamina propria demonstrated a significantly higher infiltration of FOXP3+ and IDO+ cells in inflammatory bowel disease compared to the control group (p=0.001, p=0.004, respectively). The number of IDO+ and FOXP3+ cells correlated with clinical and histopathologic activity of Crohn’s disease. A positive correlation between the number of IDO+ and FOXP3+ cells was found in both types of inflammatory disease but not in patients with IBS. We conclude that indoleamine dioxygenase and FOXP3+ cells are upregulated in the intestinal mucosa of children with inflammatory bowel disease. IDO mediated conversion of FOXP3 -T cells to Tregs predominantly occurs in inflammation.

Introduction Increased intestinal hydration by activation of the epithelial enzyme linked receptor guanylate cyclase C (GC-C) is a pharmacological principle for treating constipation. Activating mutations in the GUCY2C gene encoding GC-C cause Familial GUCY2C diarrhea syndrome (FGDS) which has been diagnosed with severe dysmotility. Aim To investigate gut motility and hormones before and after a meal in FGDS patients and compare with healthy controls (HC). Subjects and methods Bristol stool chart and stool frequency was assessed. Before and after a meal occlusive and non-occlusive contractions were obtained using ultrasound. A wireless motility capsule (WMC) recorded gut transit time, pH, contractions and pressure. Plasma levels of selected gut hormones were measured at different time points. Results The FGDS patients had 4 (range 1–10) loose stools/day and prolonged total gut transit time compared to HC, 55.5 h vs 28.5 h, respectively,with significantly increased colon transit time. In FGDS patients, pH in duodenum, small bowel and colon was increased and the number of contractions and the intraluminal pressure were significantly decreased, measured by WMC. Ultrasound showed in small bowel increased number of non-occlusive contractions in the FGDS patients. Serotonin (5-HT) plasma levels in the HC peaked 30 min after the meal, while the FGDS patients had no response. Conclusion Despite having diarrhea, the FGDS patients have prolonged transit time through the gut compared to HC, particularly in colon. The reduced number of intestinal contractions and lack of 5-HT release after a meal in FGDS patients surprisingly resemble colonic motility disturbances seen in patients with constipation.

Enterobiasis (oxyuriasis) is a common infection in human caused by Enterobius vermicularis (E. vermicularis), a human intestinal helminth. Because of the easy way of its transmission among people, it has an extremely high prevalence in overcrowded conditions, such as nurseries and primary schools. Oxyuriasis's symptoms are extremely diverse in children, ranging from nausea, diarrhea, insomnia, irritability, recurrent cellulitis, loss of appetite, nightmares and endometritis. Here we report a curious case of oxyuriasis in the settings of a refugee camp in Greece. The patient was a 10-year old Syrian female, who presented with unusual and vague symptoms like insomnia and irritability. Given the violent background of the Syrian warzone that the patient had escaped, she was firstly diagnosed with post traumatic stress disorder (PTSD) before eventually getting correctly diagnosed with enterobiasis. This infection is the first documented case of enterobiasis in the settings of a refugee camp and can highlight the unsanitary living conditions that refugees have to endure in those camps.

Bowel-associated dermatosis - arthritis syndrome (BADAS) is a neutrophilic dermatosis characterized by cutaneous lesions that begin as erythematous macules and progress to vesiculopustular eruptions. It has been described in patients with inflammatory bowel disease as well as those who have undergone various intestinal surgeries. Pathologically, the lesions show features of vasculitis without fibrinoid necrosis. In a patient with diagnosed inflammatory bowel disease, these neutrophilic dermatoses should be viewed as external signals of bowel inflammation. Management requires long-term treatment of the underlying disease. We report a case of BADAS in a patient with ulcerative colitis in which the skin lesions were associated with increased colonic inflammation.

A perianal subcutaneous tumor involving the anal sac developed in an 8-year-old male mixed Labrador Retriever dog. Histologically, this tumor showed typical features of the solid-type carcinoma of the apocrine glands of the anal sac. However, neoplastic cells were immunoreactive for cytokeratin 8, chromogranin A, vasoactive intestinal peptide, neuron-specific enolase, and synaptophysin, and negative for S-100 protein, α-smooth muscle actin, vimentin, glucagon, insulin, somatostatin, carcinoembryonic antigen, serotonin, and parathyroid hormone-related protein. Considering the distribution of chromogranin A-positive cells within the anal sac apocrine glands, this tumor was diagnosed as neuroendocrine carcinoma originating from the apocrine glands of the anal sac.

Myenteric ganglioneuritis and encephalomyelitis were diagnosed in an umbrella cockatoo. The cockatoo exhibited clinical signs that were milder than those associated with this syndrome, such as anorexia, muscle wasting, regurgitation, depression, and changes in fecal consistency. The gross lesions also differed from earlier reports in that only the duodenum and proximal jejunum were grossly dilated. Normally the proventriculus and ventriculus are dilated without visible intestinal changes. The histopathological lesions, however, such as perivascular cuffs in the brain stem and muscular mass of the ventriculus and proventriculus, were similar to earlier reports. A virus was suspected, although transmission and isolation of a virus has not occurred in other reports and was not attempted in this case.

Mesenteric cysts are rare abdominal tumors. About 60% of these cysts occurs before 5 years of age and can be located anywhere in the gastrointestinal tract, but are most often found in the small bowel mesentery. The clinical presentation depends on the location and size of the cyst and many cases are asymptomatic and are diagnosed incidentally. The most common symptoms are abdominal pain, bloating, abdominal mass, nausea, vomiting, constipation, diarrhea, weight loss, fever and peritonitis. Complications include torsion, infarction, volvulus formation, perforation, infection, anemia, intracystic hemorrhage, intestinal obstruction and obstructive uropathy. They are typically treated by simple excision, marsupialization or segmental bowel resection and have excellent long-term prognosis.

Systemic Epstein-Barr virus (EBV)-positive T-cell lymphoproliferative disorders (LPDs) of childhood is a highly aggressive EBV-positive T/natural killer (NK)-cell LPD, which emerges in the background of chronic active EBV infection (CAEBV) or shortly after primary acute EBV infection. The clinical presentations of CAEBV are varied; patients with atypical manifestations are easily misdiagnosed. We described a 14-year-old boy suffering from digestive disorders and intermittent fever for 1 year and 9 months, whose conditions worsened and skin lesions occurred 2 months before hospitalization. He was diagnosed as inflammatory bowel diseases (IBD) and treated accordingly. His other clinical features, hepatosplenomegaly, lymphadenopathy, anemia, hypoalbuminemia, and elevated inflammatory marks, were found in hospitalization. The boy suffered from repeatedly spontaneous intestinal perforations shortly after hospitalization and died of intestinal hemorrhea. The pathological results of intestine and skin both showed EBV-positive T/NK-cell LPD (lymphoma stage).There are rare studies reporting gastrointestinal perforations in EBV-positive T/NK-cell LPD, let alone repeatedly spontaneous perforations. Based on the clinical features and pathological results of this patient, the disease progressed from CAEBV (T-cell type) to systemic EBV-positive T-cell LPD of childhood (lymphoma). Not all the patients with CAEBV could have unusual patterns of anti-EBV antibodies. However, the presence of high EBV loads (EBV-encoded early small ribonucleic acid (RNA) (EBER) in affected tissues and/or EBV deoxyribonucleic acid (DNA) in peripheral blood) is essential for diagnosing CAEBV. Maybe because of his less common clinical features for CAEBV and negative anti-EBV antibodies, the boy was not diagnosed correctly. We should have emphasized the test for EBER or EBV-DNA. Meanwhile, for the IBD patients whose manifestations were not typical, and whose conditions were not improved by suitable therapies against IBD, infectious and malignant diseases should be considered.

Background: The experience with uretero-arterial fistulas has been limited. However, the aggressive treatment of pelvic tumors with surgical resection and radiotherapy, along with liberal use of ureteral catheters, has been attributed to an increase in their incidence. Unless they are promptly diagnosed and treated, uretero-arterial fistulas are associated with considerably high rates of morbidity and mortality. Urologists need maintain a high degree of suspicion for uretero-arterial fistula in high-risk patients. We herein present the clinical course of an iliac artery-uretero-colonic fistula. Case Presentation: A 67-year-old woman with a history of colon cancer who underwent laparoscopic high anterior resection in July 2010. A ureteral stent inserted to right ureteral stricture, which developed as a result of local recurrence of the tumor in September 2010. She had undergone chemoradiotherapy, but the lesion had slowly increased in size. During the replacement of the ureteral stent in April 2016, she immediately experienced bladder tamponade, bloody bowel discharge, and hypotension. Contrast CT revealed a complex fistula between the right distal ureter and the right internal iliac artery. Furthermore, contrast medium flowed into the intestinal tract through the tumor. The patient was therefore diagnosed with internal iliac artery-uretero-colonic fistula. Arteriography revealed a right uretero-internal iliac artery fistula, and the embolization of the right internal iliac artery was performed. The right ureteral stent was removed. Her hematuria and bloody bowel discharge disappeared, but right nephrostomy was performed because she presented with acute pyelonephritis to ureteral obstruction. Conclusion: In the present case, the uretero-arterial fistula was caused by the long use of an indwelling stent, chemoradiotherapy, infection, and an increase in the size of the lesion. When a suspected uretero-arterial fistula is accompanied by bloody bowel discharge, we should consider the possibility of traffic to the intestinal tract.

Horseshoe kidney (HSK) is the most common renal fusion, which is characterized by three anatomic anomalies: ectopia, malrotation and vascular changes. Patients with HSK are prone to a variety of complications, genitourinary and non-genitourinary. In this paper, the anatomy of HSK is delineated with a great emphasis on its blood supply. After reviewing the literature, the arterial supply patterns found by each author were categorized according to the classification system proposed by Graves. The majority of HSKs were found to be supplied by renal arteries derived from the abdominal aorta below the isthmus or by vessels originating from the common iliac arteries. In addition, the abnormalities associated with HSK are highlighted and classified in anatomical variations, congenital anomalies as well as in pathologic conditions related to HSK.

Intestinal lymphangiectasia (IL) is a rare enteropathy involving the expansion and rupture of intestinal lymphatic channels. Although several reports have studied cases of primary IL (PIL), this condition is very rare, and is even less commonly encountered in infants. This study aimed to investigate the nutritional therapy and effect assessment of chylous reflux disorder caused by PIL in infants. Infantile patients were enrolled in the Affiliated Beijing Shijitan Hospital of the Capital Medical University between January 2012 and March 2014. The minimum age of onset was 4 months and the maximum age of onset was 16 months, with an average age of 4.9 months. All children were inpatient who had been diagnosed with chylous reflux syndrome (chylothorax and/or chylic abdomen) caused by PIL. Retrospective analysis and individualized nutrition therapy of these cases were carried out. Finally, nutritional therapy and prognosis of PIL were assessed and summarized. All the children survived, showed improvement in the serum total protein, albumin, and HGB levels after nutritional therapy. After comprehensive nutritional therapy, we were able to achieve diarrhea control for all the 9 patients, and after treatment, the children passed soft, yellow stools 1 to 2 times/d. After treatment, the height and weight of all patients increased to within the normal ranges of the World Health Organization standard chart. The mean serum albumin level reached 41.3 g/L. All nutrition-related indicators were found to have significant improvement compared with the baseline levels. The results revealed that nutritional therapy for the 9 children with PIL was effective, and it may be able to improve the clinical syndromes and symptoms of children with PIL and promote recovery.

Rifaximin, a non-absorbable rifamycin derivative, has published clinical efficacy in the alleviation of symptoms in patients with irritable bowel syndrome (IBS). Small intestinal bacterial overgrowth (SIBO) is associated with the pathogenesis of IBS. This study describes for the first time the antimicrobial effect of rifaximin against SIBO micro-organisms from humans. Fluid was aspirated from the third part of the duodenum from 567 consecutive patients; quantitative cultures diagnosed SIBO in 117 patients (20.6%). A total of 170 aerobic micro-organisms were isolated and the in vitro efficacy of rifaximin was studied by (i) minimum inhibitory concentration (MIC) testing by a microdilution technique and (ii) time-kill assays using bile to simulate the small intestinal environment. At a breakpoint of 32 μg/mL, rifaximin inhibited in vitro 85.4% of Escherichia coli, 43.6% of Klebsiella spp., 34.8% of Enterobacter spp., 54.5% of other Enterobacteriaceae spp., 82.6% of non-Enterobacteriaceae Gram-negative spp., 100% of Enterococcus faecalis, 100% of Enterococcus faecium and 100% of Staphylococcus aureus. For the time-kill assays, 11 E. coli, 15 non-E. coli Gram-negative enterobacteria and three E. faecalis isolates were studied. Rifaximin produced a >3 log10 decrease in the starting inoculum against most of the tested isolates at 500 μg/mL after 24h of growth. The results indicate that rifaximin has a potent effect on specific small bowel flora associated with SIBO. This conclusion should be regarded in light of the considerable time-kill effect at concentrations lower than those achieved in the bowel lumen after administration of conventional doses in humans.

Neonatal appendicitis is extremely rare, and preoperative diagnosis is challenging. This study aimed to investigate the utility of ultrasound for the diagnosis of neonatal appendicitis. Four cases of neonatal appendicitis were included in this case series. One was a female infant and the other 3 were male infants; they were aged from 10 to 17 days. Neonatal appendicitis. Four newborns in our hospital were diagnosed with neonatal appendicitis by abdominal ultrasound. Their sonographic features were summarized and compared with surgical and pathological findings. In these infants, abdominal ultrasound demonstrated ileocecal bowel dilatation, intestinal and bowel wall thickening, and localized encapsulated effusion in the right lower quadrant and the abscess area, which was assumed to surround the appendix. Ultrasound is helpful for the diagnosis of neonatal appendicitis.

Long standing hypothyroidism presenting as an ovarian mass has been well described in literature as the Van Wyk Grumbach syndrome (hypothyroidism, isosexual precocious puberty and ovarian mass). Here, authors report this entity in a 11 y 7 mo old girl child who was referred to a surgeon in view of intestinal obstruction along with a multiloculated ovarian cyst. On evaluation, she was found to have raised serum creatinine, short stature, delayed bone age and pituitary enlargement. She was diagnosed with autoimmune thyroiditis and was started on replacement therapy with thyroxine, after which the ovarian cysts regressed. This entity should be kept in mind in cases of ovarian cysts, especially those with isosexual precocity, to prevent unnecessary evaluation and surgical misadventures.

An 86-year-old Japanese man was diagnosed with stage IV lung adenocarcinoma. The patient was treated with crizotinib after echinoderm microtubule-associated protein-like 4 (EML4)-anaplastic lymphoma kinase (ALK) rearrangement was detected from his pleural effusion. He subsequently developed abdominal pain and rebound tenderness in the right lower abdomen. Contrast-enhanced abdominal CT showed a low-density area in the abdominal cavity. The size of the abscess was decreased by drainage and the administration of antibiotics. Fistulography revealed a fistula from the rectum to the abscess, and a diagnosis of lower intestinal tract perforation with abscess formation was made. Crizotinib was discontinued and treatment with alectinib was initiated. The patient remains under treatment as an outpatient at our department without adverse effects.

Stone formation within the intestinal lumen is called enterolith. This stone can encroach into the lumen causing obstruction and surgical emergency. Jejunal obstruction by an enterolith is a very rare entity and often missed preoperatively. To our knowledge, most cases of jejunal obstruction, secondary to stone, were associated with biliary disease (cholecystoenteric fistula), bezoar, jejunal diverticulosis, or foreign body. Hereby we present a rare case report of small bowel obstruction in an elderly man who was diagnosed lately to have primary proximal jejunal obstruction by an enterolith without evidence of a cholecystoenteric fistula or jejunal diverticulosis. This patient underwent laparotomy, enterotomy with stone extraction, and subsequent primary repair of the bowel.

Hereditary angioedema is an autosomal dominant disease characterized by recurrent angioedema attacks with the involvement of multiple organs. The disease is unknown to many health professionals and is therefore underdiagnosed. Patients who are not adequately diagnosed and treated have an estimated mortality rate ranging from 25% to 40% due to asphyxiation by laryngeal angioedema. Intestinal angioedema is another important and incapacitating presentation that may be the main or only manifestation during an attack. In this article, a group of experts from the "Associação Brasileira de Alergia e Imunologia (ASBAI)" and the "Grupo de Estudos Brasileiro em Angioedema Hereditário (GEBRAEH)" has updated the Brazilian guidelines for the diagnosis and treatment of hereditary angioedema.

Microvillus inclusion disease (MVID) is a disorder of intestinal epithelial differentiation characterized by life-threatening intractable diarrhea. MVID can be diagnosed based on loss of microvilli, microvillus inclusions, and accumulation of subapical vesicles. Most patients with MVID have mutations in myosin Vb that cause defects in recycling of apical vesicles. Whole-exome sequencing of DNA from patients with variant MVID showed homozygous truncating mutations in syntaxin 3 (STX3). STX3 is an apical receptor involved in membrane fusion of apical vesicles in enterocytes. Patient-derived organoid cultures and overexpression of truncated STX3 in Caco-2 cells recapitulated most characteristics of variant MVID. We conclude that loss of STX3 function causes variant MVID.

Roux Stasis Syndrome is a well-known complication after Roux-en-Y reconstruction. Uncut Roux-en-Y technique, would preserve unidirectional intestinal myoelectrical activity and diminish Roux Stasis Syndrome. A 61 years old woman with moderately differentiated adenocarcinoma of antrum who was diagnosed by gastroscopy and histological test, underwent totally laparoscopic distal gastrectomy (TLDG) with D2 lymph node dissection and uncut Roux-en-Y reconstruction (URYR). The length of operation was 190 min with bleeding of about 40 mL. The patient recovers well postoperation and discharged from hospital on the 7 th day. TLDG with intracorporeal uncut Roux-en-Y gastrojejunostomies using laparoscopic linear staplers was safe and feasible with minimal invasiveness.

Epstein-Barr virus (EBV) plays an important role in various diseases. EBV-associated lymphoproliferative disease (LPD) is a rare disease with a canceration tendency. It is difficult to differentiate LPD with involvement of digestive tract from Crohn disease due to similar clinical and endoscopic manifestations. We present a case report of multiple ulcers with esophagus, small bowel and the entire colon involved, proved to be NK-Cell LPD, developed into EBV-associated NK/T Cell lymphoma, in an immunocompetent man who was initially misdiagnosed as Crohn disease.This report underscores that intestinal ulcers should be cautiously diagnosed, for it sometimes could be a precancerous lesion.

Our aim was to assess if term and preterm infants with volvulus showed different patterns with regard to pathogenesis, clinical presentation and outcome. We reviewed the medical records and imaging data of infants aged less than six months with volvulus treated in a single surgical referral centre from 2006-2013. Volvulus was diagnosed in 19 infants, with no anatomical anomaly in three of the 12 preterm infants and one of the seven term infants. Most cases (74%) presented during the first eight days of life. Later presentations occurred exclusively in preterm infants, with only one of the five having no anatomic anomalies. Bilious vomiting was the leading symptom in six of the seven term infants, while the symptoms in preterm infants were rather nonspecific. Intestinal necrosis, with the need for bowel resection, occurred in one term (14%) infant and nine (75%) preterm infants. The clinical presentation and outcome of volvulus differed between preterm and term infants, but the rate and distribution of underlying anomalies did not differ. Symptoms in preterm infants were often nonspecific and led to a delay in diagnosis. This might have contributed to the higher rate of intestinal necrosis in preterm infants. ©2016 Foundation Acta Paediatrica. Published by John Wiley & Sons Ltd.

Selective intestinal malabsorption of vitamin B12 displays recessive Mendelian inheritance: Assignment of a locus to chromosome 10 by linkage

Aminoff, M.; Tahvanainen, E.; Chapelle, A. de la

Juvenile megaloblastic anemia caused by selective intestinal malabsorption of vitamin B12 has been considered a distinct condition displaying autosomal recessive inheritance. It appears to have a worldwide distribution, and comparatively high incidences were reported 30 years ago in Finland and Norway. More recently, the Mendelian inheritance of the condition has been questioned because almost no new cases have occurred in these populations. Here we report linkage studies assigning a recessive-gene locus for the disease to chromosome 10 in previously diagnosed multiplex families from Finland and Norway, proving the Mendelian mode of inheritance. The locus is tentatively assigned to the 6-cMmore » interval between markers D10S548 and D10S466, with a multipoint maximum lod score (Z{sub max}) of 5.36 near marker D10S1477. By haplotype analysis, the healthy sibs in these families did not appear to constitute any examples of nonpenetrance. We hypothesize that the paucity of new cases in these populations is due either to a dietary effect on the gene penetrance that has changed with time, or to a drop in the birth rate in subpopulations showing enrichment of the mutation, or to both of these causes. 38 refs., 4 figs., 2 tabs.« less

OBJECTIVE: To investigate the prevalence and risk factors for wheezing disorders in early childhood in São Paulo, Brazil, the largest metropolitan area of South America. METHODS: A population-based cross-sectional survey of 1132 children aged 6-59 months was carried out between 1995 and 1996 to obtain information on recent wheezing and on independent variables such as demographic, socioeconomic, environmental, maternal and nutritional variables and immunization status. Intestinal parasitic infections were diagnosed using standard techniques. Multiple unconditional logistic regression was used to describe associations between outcome and independent variables. FINDINGS: The prevalence of recent wheezing (one or more reported episodes in the past 12 months) was 12.5%; 93% of children with wheezing were also reported to have a medical diagnosis of asthma. Recent wheezing was associated with low per capita income, poor quality of housing, day-care attendance, low birth weight and infection with intestinal helminths. CONCLUSION: Wheezing in early childhood in São Paulo, although more common than in most developing countries, remains less prevalent than in urban areas of industrialized countries. Low income and conditions associated with poverty (poor housing, low birth weight and parasitic infections) are some of the main risk factors for wheezing disorders among young children in this city.

The patient was 55-year-old woman, undergoing Hartmann operation by the sigmoid colon diverticulum perforation, 2 years later visited our hospital with abdominal pain. Although lower endoscopy and histological examination could not be performed due to stoma stenosis, we diagnosed cecal carcinoma, liver metastasis, distant lymph node metastasis from CT and PET-CT, CapeOX plus Bmabtherapy and IRIS plus Bmabtherapy were performed. After that, repeated intestinal obstruction due to exacerbated stoma stenosis, metastatic lesion increased in CT examination, furthermore the patient had hope of stoma closure, we decided to resect the primacy tumor, performed subtotal colonectomy and stoma closure. Pathological diagnosis revealed RAS wild type. After surgery, Pmabplus CPT-11 therapy was performed and the metastatic lesion was temporarily shrunk but re-exacerbated, the patient died 2 years 2 months after the first treatment started, 7 months after the primary tumor resection. In the treatment of colorectal cancer, when metastatic lesion is unresectable, chemotherapy is often carried out except when the primary tumor is symptomatic. In our case, although the primary tumor was asymptomatic, an intestinal obstruction due to stoma stenosis was developed and it was necessary to examine whether to use anti-EGFR antibody drugs, therefore we performed operation.

Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal tumors of the gastrointestinal tract. The small intestine is the second-most frequent location where GISTs occur after the stomach. Attention should be paid to small intestinal GISTs because they infrequently present with acute abdomen, which necessitates emergency surgery. This report describes a patient with a small intestinal GIST developing a giant intratumoral abscess, in whom emergency surgery was performed. A 56-year-old woman presented with worsening abdominal pain. Computed tomography scan showed an approximately 9.5 cm × 9 cm tumor bearing a thick and hypervascularized wall with an internal air-fluid level. Emergency laparotomy revealed the tumor originated from the jejunum, and partial resection of the jejunum was performed. A large amount of pus was contained inside the tumor. Immunohistochemically, the tumor was diagnosed as a high risk GIST of the Cjejunum, and imatinib mesylate was initiated. When an intratumoral abscess in the abdomen is confirmed, GISTs should be listed as differential diagnosis. Complete surgical resetcion with careful handling and adjuvant chemotherapy with imatinib mesylate are considered to be important for this state. Copyright © 2018 The Authors.

Primary intestinal lymphangiectasia in children: is octreotide an effective and safe option in the treatment?

PubMed

Sari, Sinan; Baris, Zeren; Dalgic, Buket

2010-10-01

Octreotide has been suggested as a medical treatment option in refractory cases of primary intestinal lymphangiectasia (IL). There are few data about the long-term effect and safety of octreotide for IL in the literature. In the present article we analyzed pediatric cases of primary IL with long-term octreotide treatment and discussed its safety profile. Between 1999 and 2008, 13 children were diagnosed in our clinic as having IL. Six patients with primary IL were followed up, receiving octreotide therapy. The clinical data of the patients and duration of therapy, dose, and side effects of octreotide were evaluated. Octreotide, 15 to 20 μg per body weight 2 times daily subcutaneously, was given to all of the patients. Duration of the octreotide treatment changed between 3 and 37 months. Stool frequency decreased in all of the patients after starting octreotide treatment. Serum albumin could be maintained at normal levels in 3 patients. The requirement of albumin infusions decreased in all of the patients. Acute pancreatitis was observed as a side effect of octreotide in 1 patient. Octreotide may help to maintain serum albumin levels, improve clinical findings, and decrease the requirement of albumin infusions in refractory cases of primary IL.

Chronic gastritis in China: a national multi-center survey

PubMed Central

2014-01-01

Background Chronic gastritis is one of the most common findings at upper endoscopy in the general population, and chronic atrophic gastritis is epidemiologically associated with the occurrence of gastric cancer. However, the current status of diagnosis and treatment of chronic gastritis in China is unclear. Methods A multi-center national study was performed; all patients who underwent diagnostic upper endoscopy for evaluation of gastrointestinal symptoms from 33 centers were enrolled. Data including sex, age, symptoms and endoscopic findings were prospectively recorded. Results Totally 8892 patients were included. At endoscopy, 4389, 3760 and 1573 patients were diagnosed to have superficial gastritis, erosive gastritis, and atrophic gastritis, respectively. After pathologic examination, it is found that atrophic gastritis, intestinal metaplasia and dysplasia were prevalent, which accounted for 25.8%, 23.6% and 7.3% of this patient population. Endoscopic features were useful for predicting pathologic atrophy (PLR = 4.78), but it was not useful for predicting erosive gastritis. Mucosal-protective agents and PPI were most commonly used medications for chronic gastritis. Conclusions The present study suggests non-atrophic gastritis is the most common endoscopic finding in Chinese patients with upper GI symptoms. Precancerous lesions, including atrophy, intestinal metaplasia and dysplasia are prevalent in Chinese patients with chronic gastritis, and endoscopic features are useful for predicting pathologic atrophy.

To detect the presence of microsporidia and other enteric parasites in patients with HIVAIDS of the Autonomous Services University Hospital of Maracaibo (SAHUM), where there are no previous studies in this field. Fecal samples were analyzed by means of direct exam, concetration method with formal-ether, Kinyoun coloration and fast Gram-Chromotrope coloration. Separate PCR were perfomed to differentiate Entamoeba histolytica and Entamoeba dispar , when the E. histolytica/E. dispar complex was observed in the microscope. Information on the patient was obtained trough clinical history. Of 56 individuals that participated, 38 (67.86%) presented some commensal parasite and/ or pathogenic species in their fecal sample. Carriers of pathogenic species were predominat (26/38). Protozoa such as Isospora belli protozoa (17.65%), Blastocystis spp. (17.65%), Cryptosporidium spp. (7.84%), E. histolytica/E. dispar (5.88%), Entamoeba coli (3.92%), Giardia lamblia (3.92%), Endolimax nana (3.92%), Cyclospora cayetanensis (3.92%), and Chilomastix mesnilli (1.96%) were diagnosed. Among the helminths, Ascaris lumbricoides, Trichuris trichiura and Strongyloides stercoralis , had a percentage of 27.27% each, and Hymenolepis nana , 18.18%. Entamoeba histolytica was only detected in one of three cases presenting complex microscopic examination. By Gram-chromotrope, 17 samples showed spores of the Microsporidia phylum, equivalent to 33.33% prevalence. Microsporidia may be first prevalente in HIV positive patients when specific diagnostic techniques are used.

To evaluate a new monoclonal antibody for Helicobacter pylori urease in gastric tissue. A total of 107 volunteers were enrolled. All subjects underwent a (13)C-urea breath test and esophagogastroduodenoscopy. Gastric aspirates were analyzed for pH and ammonia. Six biopsy specimens in the gastric antrum and body were obtained for a rapid urease test and histology. The new monoclonal antibody-based H. pylori urease test (HPU) was performed to rapidly and qualitatively detect urease in two biopsy specimens. H. pylori infection was diagnosed in 73 subjects. The sensitivity and specificity of the HPU was 89% and 74%, respectively. The subjects were divided into two groups: one with true-positive and true-negative HPU results (n = 90) and the other with false-positive and false-negative HPU results (n = 17). Across all subjects, ammonia levels were 900.5 ± 646.7 and 604.3 ± 594.3 μmol/L (p > 0.05), and pH was 3.37 ± 1.64 and 2.82 ± 1.51 (p > 0.05). Sensitivity was higher in the presence of atrophic gastritis or intestinal metaplasia. HPU detected H. pylori in approximately 10 min. Gastric aspirate ammonia and pH levels did not affect the test results. Sensitivity was good in the presence of atrophic gastritis or intestinal metaplasia.

Brucellosis is a multisystem infection found worldwide that has a broad range of characteristics, which range from acute fever and hepatomegaly to chronic infections that most commonly affect the central nervous system, cardiovascular system, or skeletal system. Gastrointestinal and splanchnic artery involvements in brucellosis are relatively uncommon. We report a case of brucellosis in an adolescent presenting as intermittent abdominal pain, diarrhea, and fever, with intestinal tract involvement. And stenosis of the celiac artery and the superior mesenteric artery was found after exposed to risk factors of Brucella infection. Splanchnic vessels stenosis and an endothelial lesion may exacerbate the prevalent symptom of abdominal pain, as a form of colic pain, occurring after eating. The patient was diagnosed as brucellosis. The narrowing of the SMA and CA was suspected to be vasculitis secondary to the brucellosis. The patient was treated with minocycline and rifampicin for 12 weeks totally. The gastrointestinal manifestations of brucellosis recovered rapidly under intensive treatment. However, follow-up imaging revealed that the superior mesenteric artery and celiac artery stenosis was unimproved. In brucellosis, gastrointestinal manifestations may be the only observable features of the disease. Splanchnic arterial stenosis is a rare complication of brucellosis. Sonography and computed tomography may be useful for both diagnosis and follow-up.

We present a case of neonatal ovarian torsion complicated by bowel obstruction and perforation and review the literature regarding the incidence of bowel obstruction in neonatal ovarian cysts, the presentation, and treatment. A term neonate was prenatally diagnosed with a cystic abdominal mass palpable on physical examination. A postnatal abdominal x-ray showed paucity of gas in the left hemiabdomen with rightward displacement of bowel loops. Exploratory laparotomy on day 2 of life revealed a large cystic mass in the left lower quadrant consistent with a torsed left ovary, an omental band causing strangulation of the bowel mesentery, and a perforation of the distal ileum. Our literature search revealed 19 reported cases of neonatal ovarian cysts resulting in bowel obstruction. Infants may present with a palpable abdominal mass, respiratory distress, as well as signs and symptoms of intestinal obstruction. Two mechanisms exist for bowel obstruction: adhesions caused by a torsed necrotic ovary and mass effect of a large ovarian cyst, often measuring 9 to 10 cm in diameter. Options to treat ovarian cysts include antenatal or postnatal aspiration, laparoscopy, and laparotomy. Cysts less than 4 to 5 cm can be observed, whereas operative intervention is indicated in symptomatic cases and in persistent or enlarging ovarian cysts. Copyright 2010 Elsevier Inc.

The dermatological manifestations associated with intestinal diseases are becoming more frequent, especially now when new clinical entities, such as Non-Celiac Gluten Sensitivity (NCGS), are identified. The existence of this new entity is still debated. However, many patients with diagnosed NCGS that present intestinal manifestations have skin lesions that need appropriate characterization. We involved 17 patients affected by NCGS with non-specific cutaneous manifestations who got much better after a gluten free diet. For a histopathological and immunopathological evaluation, two skin samples from each patient and their clinical data were collected. The median age of the 17 enrolled patients affected by NCGS was 36 years and 76% of them were females. On the extensor surfaces of upper and lower limbs in particular, they all presented very itchy dermatological manifestations morphologically similar to eczema, psoriasis or dermatitis herpetiformis. This similarity was also confirmed histologically, but the immunopathological analysis showed the prevalence of deposits of C3 along the dermo-epidermal junction with a microgranular/granular pattern (82%). The exact characterization of new clinical entities such as Cutaneous Gluten Sensitivity and NCGS is an important objective both for diagnostic and therapeutic purposes, since these are patients who actually benefit from a GFD (Gluten Free Diet) and who do not adopt it only for fashion.

A 78-year-old woman who had recurrent right lower abdominal pain for about 1 year underwent computed tomography (CT) because of a follow-up observation 1 year after right breast cancer surgery. CT revealed a tumor in the colon. The patient was referred to our hospital for detailed examinations. An abdominal CT showed a low-density tumor of approximately 30 mm in the ascending colon, and the CT density inside the tumor was same as that of fatty tissues. A subsequent colonoscopy showed a submucosal tumor (SMT) in the proximal ascending colon developing from the terminal ileum. A colonoscopic ultrasonography revealed that the SMT was a high-echoic mass mainly localized in the submucosal layer. Based on the findings from CT, colonoscopy, and colonoscopic ultrasonography, the SMT was diagnosed as a pedunculated lipoma originating from the terminal ileum and treated with endoscopic submucosal dissection (ESD) because of recurrent abdominal pain. The 40-mm tumor was resected en bloc without complications. ESD may be more appropriate than polypectomy and surgery for removal of small intestinal tumors, because ESD allows direct visualization of the cutting line and exactly dissects the submucosal layers without damaging the muscular layers. ESD is a potentially useful treatment to remove intestinal lipomas. PMID:27843426

This study was designed to evaluate the antigen capture enzyme immunoassays (EIAs) Triage parasite panel and TechLab Entamoeba histolytica II in detecting Giardia intestinalis, Cryptosporidium sp, and Entamoeba histolytica in fecal samples in comparison to microscopy, and in differentiating Entamoeba histolytica from Entamoeba dispar. The Triage EIA was evaluated using 100 stool specimens that were tested by standard ova and parasite examination, including staining with both trichrome and modified acid-fast stains. Differentiation between E. histolytica and E. dispar was performed using TechLab. Microscopic examination revealed that 19% of the samples were positive for Giardia, 4% for Cryptosporidium, and 1% for E. histolytica/E. dispar, and other parasites were found in 5%. By Triage, 23% of the samples were infected with Giardia, 5% with Cryptosporidium, and 2% with E. histolytica/E. dispar. Triage showed a sensitivity of 100% and specificity of 91.5%. The TechLab assay was negative for both samples diagnosed as E. histolytica/E. dispar by Triage, which suggested that they were E. dispar. Both tests showed no cross-reactivity with other intestinal protozoa. These results indicate that antigen detection by EIA has the potential to become a valuable tool, capable of making stool diagnostics more effective.

Early diagnosis and curative resection are the predominant factors associated with increased survival in patients with gastric cancer. However, most gastric cancer cases are still diagnosed at later stages. Since most pathologic specimens are archived as FFPE samples, the ability to use them to generate expression profiles can greatly improve cancer biomarker discovery. We sought to uncover new biomarkers for stomach preneoplastic metaplasias and neoplastic lesions by generating proteome profiles using FFPE samples. We combined peptide isoelectric focusing and liquid chromatography–tandem mass spectrometry analysis to generate proteomic profiles from FFPE samples of intestinal-type gastric cancer, metaplasia, and normal mucosa. The expression patterns of selected proteins were analyzed by immunostaining first in single tissue sections from normal stomach, metaplasia, and gastric cancer and later in larger tissue array cohorts. We detected 60 proteins up-regulated and 87 proteins down-regulated during the progression from normal mucosa to metaplasia to gastric cancer. Two of the up-regulated proteins, LTF and DMBT1, were validated as specific markers for spasmolytic polypeptide–expressing metaplasia and intestinal metaplasia, respectively. In cancers, significantly lower levels of DMBT1 or LTF correlated with more advanced disease and worse prognosis. Thus, proteomic profiling using FFPE samples has led to the identification of two novel markers for stomach metaplasias and gastric cancer prognosis. PMID:22944598

Diets high in red and processed meats are associated with carcinogenesis of the large intestine, but no prospective study has examined meat and fat intake in relation to cancer of the small intestine. We prospectively investigated meat and fat intakes, estimated from a food frequency questionnaire, in relation to small intestinal cancer among half a million men and women enrolled in the NIH-AARP Diet and Health Study. We used Cox proportional hazards regression to estimate hazard ratios (HR) and 95% confidence intervals (95% CI). During up to 8 years of follow-up, 60 adenocarcinomas and 80 carcinoid tumors of the small intestine were diagnosed. Despite slightly elevated HRs for red meat, there were no clear associations for red or processed meat intake and either adenocarcinoma or carcinoid tumors of the small intestine. In contrast, we noted a markedly elevated risk for carcinoid tumors of the small intestine with saturated fat intake in both the categorical (highest versus lowest tertile: HR, 3.18; 95% CI, 1.62-6.25) and continuous data (HR, 3.72; 95% CI, 1.79-7.74 for each 10-g increase in intake per 1,000 kcal). Our findings suggest that the positive associations for meat intake reported in previous case-control studies may partly be explained by saturated fat intake.

Actinomycosis is a chronic suppurative granulomatous disease caused by Actinomyces israelii. Preoperative confirmed diagnosis is very difficult, so most cases are diagnosed preoperatively as malignant tumors. We report a case of intraabdominal actinomycosis which was difficult to diagnose preoperatively. A woman, 60 years old, experienced discomfort in her lower right abdomen. She complained of nausea and anorexia and visited our hospital. Laboratory blood tests, abdominal CT, and abdominal MRI led to a diagnosis of a uterine sarcoma or primary intestinal mass, and she underwent surgery. Her histopathological diagnosis was intraabdominal actinomycosis. Actinomycosis is a chronic purulent granulomatous inflammation caused by Actinomyces israelii. No clinical symptoms or laboratory findings are characteristic of abdominal actinomycosis, so this disorder is very difficult to diagnose preoperatively. Therefore, many cases are diagnosed as malignant tumors and undergo surgery. After surgery, long-term antibiotic treatment (penicillin) is usually administered. We reported a case of intraabdominal actinomycosis that resulted in a difficult to diagnose intraperitoneal mass. When a large intraperitoneal mass is found, actinomycosis needs to be included as one of differential diagnoses. Copyright © 2018 The Authors. Published by Elsevier Ltd.. All rights reserved.

　Most gastric bezoars can be treated with endoscopic fragmentation combined with or without cola dissolution, whereas laparotomy or laparoscopic surgery is generally inevitable for small intestinal bezoars because they cause small bowel obstruction. Therefore, early diagnosis and management of gastric bezoars are necessary to prevent bezoar-induced ileus. To investigate the incidence of overlooked gastric bezoars during the initial esophagogastroduodenoscopy, we retrospectively reviewed the cases of 27 patients diagnosed with gastrointestinal bezoars. The bezoars were diagnosed using esophagogastroduodenoscopy (n=25), abdominal ultrasonography (n=1), and barium follow-through examination (n=1). Bezoars were overlooked in 9/25 patients (36.0%) during the initial endoscopy examination because the bezoars were covered with debris in the stomach. Of the 9 patients, 8 had concomitant gastric ulcers, and the other patient had gastric lymphoma. Although a computed tomography (CT) scan was performed before the second-look endoscopy in 8 of the 9 patients, the bezoars were mistaken as food debris on CT findings and were overlooked in these patients. In conclusion, gastric bezoars may not be discovered during the initial esophagogastroduodenoscopy and CT scan. In cases with debris in the stomach, second-look endoscopy is essential to detect bezoars.

Predisposing factors for colonic torsion/volvulus in dogs: a retrospective study of six cases (1992-2010).

The purposes of this retrospective study were to review cases of colonic torsion/volvulus between July 1992 and August 2010 and to determine if any predisposing factors exist for the development of this condition. Six dogs were diagnosed with colonic torsion/volvulus during the study period. Four dogs had a history of previous gastric dilation-volvulus (GDV) with prophylactic gastropexy. Three of six dogs diagnosed with colonic torsion/volvulus had large intestinal entrapment and strangulation around the gastropexy site at the time of surgery. The history, clinical signs, physical examination, and radiologic findings were not specific for colonic torsion/volvulus in any dog. Early exploratory laparotomy was indicated to confirm the diagnosis and perform surgical correction of the affected bowel segments. Three of five dogs that underwent surgery had a left abdominal wall colopexy performed. All five dogs that underwent surgery in this study survived postoperatively. One patient was euthanized without surgical intervention. Results suggest that colonic torsion/volvulus should be considered in any large-breed dog with nonspecific gastrointestinal clinical signs and a history of previous gastropexy. Early recognition and prompt treatment of this condition may result in a good outcome.

Pathophysiology of avian intestinal ion transport.

PubMed

2018-06-01

The gut has great importance for the commercial success of poultry production. Numerous ion transporters, exchangers, and channels are present on both the apical and the basolateral membrane of intestinal epithelial cells, and their differential expression along the crypt-villus axis within the various intestinal segments ensures efficient intestinal absorption and effective barrier function. Recent studies have shown that intensive production systems, microbial exposure, and nutritional management significantly affect intestinal physiology and intestinal ion transport. Dysregulation of normal intestinal ion transport is manifested as diarrhoea, malabsorption, and intestinal inflammation resulting into poor production efficiency. This review discusses the basic mechanisms involved in avian intestinal ion transport and the impact of development during growth, nutritional and environmental alterations, and intestinal microbial infections on it. The effect of intestinal microbial infections on avian intestinal ion transport depends on factors such as host immunity, pathogen virulence, and the mucosal organisation of the particular intestinal segment.

Gastric intestinal metaplasia (GIM) is a common finding from routine endoscopies. Although GIM is an early step in gastric carcinogenesis, there is controversy regarding routine surveillance of patients with GIM in regions with a low prevalence of gastric cancer. We aimed to determine the incidence of gastric cancer among patients with GIM and risk factors for gastric cancer. We performed a retrospective cohort study of patients from the Kaiser Permanente Southern California region diagnosed with GIM from 2000 through 2011. GIM was identified by a keyword search of pathology reports; gastric cancer cases were identified by cross-reference with an internal cancer registry. The incidence of gastric cancer in patients with GIM (n = 923; median age at diagnosis, 68 y) was compared with that of an age- and sex-matched reference population (controls). Risk factors such as ethnicity, smoking status, history of Helicobacter pylori infection, and family history of gastric cancer were evaluated by individual Cox proportional hazards regression. We then performed a second case-cohort study to evaluate the risk of gastric cancer based on the location and extent of GIM. The median duration of follow-up evaluation was 4.6 years (interquartile range, 3.0-6.7 y). We identified 25 patients with GIM who developed gastric cancers. Seventeen cases of cancer were diagnosed at the same time as the diagnosis of GIM. Eight cases of cancer were identified within a median time period of 4.6 years after a diagnosis of GIM (interquartile range, 2-5.7 y). The overall incidence rate for the cohort was 1.72 (95% confidence interval, 0.74-3.39). Among the risk factors evaluated, only family history (hazard ratio, 3.8; 95% confidence interval, 1.5-9.7; P = .012) and extent of GIM (odds ratio, 9.4; 95% confidence interval, 1.8-50.4) increased the risk for gastric cancer. The incidence rate for gastric cancer in patients with a positive family history was 8.12 (95% confidence interval, 1.67-23.73). In an analysis of patients with GIM listed in the Kaiser Permanente Southern California database, 2.7% were diagnosed with gastric cancer; almost 70% of cases of gastric cancer were detected at the time of GIM diagnosis. Family history and extensive metaplasia were associated with an increased risk of subsequent gastric cancer. Targeted surveillance of patients with these criteria could increase early detection of gastric cancer. Copyright © 2016 AGA Institute. Published by Elsevier Inc. All rights reserved.

In some surgical techniques like femoral derotation osteotomy, accuracy is a key factor that often is not optimal because of the lack of appropriate technology. 3D printing is emerging in many professional areas and its use in the medical field may enhance the results of certain surgeries. This case describes a patient who underwent an intramedullary nail fixation to treat a femoral shaft fracture. After nine months, the patient presented hip pain and "in toe" walking caused by a malrotation produced during the surgery. To address the consequent femoral derotation osteotomy, 3D technology was used throughout the whole process. A 3D model of the patient's femur was created to conduct a real and accuracy assessment of femoral anteversion. Then, a customized surgical guide was designed and printed to ensure the proper alignment during surgery. Given the success of this surgery, 3D printing can be considered a quick and inexpensive tool to improve surgical results.

Which Tibial Tray Design Achieves Maximum Coverage and Ideal Rotation: Anatomic, Symmetric, or Asymmetric? An MRI-based study.

2015-10-01

Two goals of tibial tray placement in TKA are to maximize coverage and establish proper rotation. Our purpose was to utilize MRI information obtained as part of PSI planning to determine the impact of tibial tray design on the relationship between coverage and rotation. MR images for 100 consecutive knees were uploaded into PSI software. Preoperative planning software was used to evaluate 3 different tray designs: anatomic, symmetric, and asymmetric. Approximately equally good coverage was achieved with all three trays. However, the anatomic compared to symmetric/asymmetric trays required less malrotation (0.3° vs 3.0/2.4°; P < 0.001), with a higher proportion of cases within 5° of neutral (97% vs 73/77%; P < 0.001). In this study, the anatomic tibia optimized the relationship between coverage and rotation. Copyright © 2015 Elsevier Inc. All rights reserved.

Diagnosis and Management of Low-Grade Dysplasia in Barrett's Esophagus: Expert Review From the Clinical Practice Updates Committee of the American Gastroenterological Association.

PubMed

Wani, Sachin; Rubenstein, Joel H; Vieth, Michael; Bergman, Jacques

2016-11-01

The purpose of this clinical practice update expert review is to define the key principles in the diagnosis and management of low-grade dysplasia (LGD) in Barrett's esophagus patients. The best practices outlined in this review are based on relevant publications, including systematic reviews and expert opinion (when applicable). Practice Advice 1: The extent of Barrett's esophagus should be defined using a standardized grading system documenting the circumferential and maximal extent of the columnar lined esophagus (Prague classification) with a clear description of landmarks and visible lesions (nodularity, ulceration) when present. Practice Advice 2: Given the significant interobserver variability among pathologists, the diagnosis of Barrett's esophagus with LGD should be confirmed by an expert gastrointestinal pathologist (defined as a pathologist with a special interest in Barrett's esophagus-related neoplasia who is recognized as an expert in this field by his/her peers). Practice Advice 3: Expert pathologists should report audits of their diagnosed cases of LGD, such as the frequency of LGD diagnosed among surveillance patients and/or the difference in incidence of neoplastic progression among patients diagnosed with LGD vs nondysplastic Barrett's esophagus. Practice Advice 4: Patients in whom the diagnosis of LGD is downgraded to nondysplastic Barrett's esophagus should be managed as nondysplastic Barrett's esophagus. Practice Advice 5: In Barrett's esophagus patients with confirmed LGD (based on expert gastrointestinal pathology review), repeat upper endoscopy using high-definition/high-resolution white-light endoscopy should be performed under maximal acid suppression (twice daily dosing of proton pump inhibitor therapy) in 8-12 weeks. Practice Advice 6: Under ideal circumstances, surveillance biopsies should not be performed in the presence of active inflammation (erosive esophagitis, Los Angeles grade C and D). Pathologists should be informed if biopsies are obtained in the setting of erosive esophagitis and if pathology findings suggest LGD, or if no biopsies are obtained, surveillance biopsies should be repeated after the anti-reflux regimen has been further intensified. Practice Advice 7: Surveillance biopsies should be performed in a four-quadrant fashion every 1-2 cm with target biopsies obtained from visible lesions taken first. Practice Advice 8: Patients with a confirmed histologic diagnosis of LGD should be referred to an endoscopist with expertise in managing Barrett's esophagus-related neoplasia practicing at centers equipped with high-definition endoscopy and capable of performing endoscopic resection and ablation. Practice Advice 9: Endoscopic resection should be performed in Barrett's esophagus patients with LGD with endoscopically visible abnormalities (no matter how subtle) in order to accurately assess the grade of dysplasia. Practice Advice 10: In patients with confirmed Barrett's esophagus with LGD by expert GI pathology review that persists on a second endoscopy, despite intensification of acid-suppressive therapy, risks and benefits of management options of endoscopic eradication therapy (specifically adverse events associated with endoscopic resection and ablation), and ongoing surveillance should be discussed and documented. Practice Advice 11: Endoscopic eradication therapy should be considered in patients with confirmed and persistent LGD with the goal of achieving complete eradication of intestinal metaplasia. Practice Advice 12: Patients with LGD undergoing surveillance rather than endoscopic eradication therapy should undergo surveillance every 6 months times 2, then annually unless there is reversion to nondysplastic Barrett's esophagus. Biopsies should be obtained in 4-quadrants every 1-2 cm and of any visible lesions. Practice Advice 13: In patients with Barrett's esophagus-related LGD undergoing ablative therapy, radiofrequency ablation should be used. Practice Advice 14: Patients completing endoscopic eradication therapy should be enrolled in an endoscopic surveillance program. Patients who have achieved complete eradication of intestinal metaplasia should undergo surveillance every year for 2 years and then every 3 years thereafter to detect recurrent intestinal metaplasia and dysplasia. Patients who have not achieved complete eradication of intestinal metaplasia should undergo surveillance every 6 months for 1 year after the last endoscopy, then annually for 2 years, then every 3 years thereafter. Practice Advice 15: Following endoscopic eradication therapy, the biopsy protocol of obtaining biopsies in 4 quadrants every 2 cm throughout the length of the original Barrett's esophagus segment and any visible columnar mucosa is suggested. Practice Advice 16: Endoscopists performing endoscopic eradication therapy should report audits of their rates of complete eradication of dysplasia and intestinal metaplasia and adverse events in clinical practice.

In children diagnosed with celiac disease, fat soluble vitamin levels were aimed to be evaluated and it was intended to determine whether fat soluble vitamin levels were needed to be assessed routinely in these patients during diagnosis. Between May 2015-May 2016, diagnosis symptoms of celiac patients (CD) in newly diagnosed pediatric group were questioned, fat soluble vitamin levels simultaneous with intestinal biopsies were evaluated. Vitamin levels were compared with those of healthy control group. A total of 52 patients involving 27 female (51.9%), 25 male (48.1%); and a total of 50 healthy control group including 25 female (50%), 25 male (50%) were evaluated. The average age of patients was 9 ± 4.3 years, and their average weight was determined as 16.2 ± 6.3 kg. Growth retardation was the most frequent symptom in our patients (61.5%). Abdominal pain (51.9%) and diarrhea (11.5%) are among the other most commonly seen symptoms. In the histological examination of patients, Marsh 3B n = 23 (45.1%) was mostly established. Vitamin A and vitamin D levels of patients were determined significantly lower compared to those of control group. Vitamin A and vitamin D deficiencies were identified significantly higher compared to those of healthy control group. Vitamin D insufficiency was observed in 48 patients (92.3%) and vitamin D deficiency was determined in 32 (61.5%) out of 48. Vitamin A deficiency was established in 17 (32.7%) patients. Vitamin E and vitamin K1 deficiency were determined in no patients. In the healthy control group, vitamin D deficiency was seen in 2 (4%) patients, vitamin D insufficiency was determined in 9 (18%) patients. Other vitamin levels were identified at normal levels in the healthy group. In newly diagnosed children with CD, a significant lowness was established in vitamin D and A. The evaluation of vitamin A and D levels will be helpful in the course of diagnosis in these patients.

2006-01-01

VPS, a hot water extract of the Coriolus versicolor mushroom, was given at a 2% dose level in the diet of female Swiss Webster CFW outbred mice in a serial sacrifice experiment. The mice were also administered either 1,2-dimethylhydrazine dihydrochloride (1,2-DMH) as ten weekly subcutaneous (s.c) injections of 20 microg/g body weight or physiological saline (PS) as ten weekly (s.c) injections of 0.01 ml/g body weight. The animals were sacrificed at 26 weeks or 35 weeks after the first injection of 1,2-DMH or PS. The number of mice with large intestinal tumors and the total number of these tumors were: Group I (1,2-DMH), 29 and 438; Group 2 (VPS + 1,2-DMH), 29 and 344; Group 3 (VPS + PS), 0 and 0; and Group 4 (PS), I and 1, in the mice sacrificed at 26 weeks. The corresponding tumor incidences in mice sacrificed at 35 weeks were: Group 1 (1,2-DMH), 30 and 323; Group 2 (VPS + 1,2-DMH), 29 and 521; Group 3 (VPS + PS), 1 and 2; and Group 4 (PS), 0 and 0. Histopathologically, the tumors were diagnosed as polypoid adenomas and adenocarcinomas of the cecum, colon and rectum. Contrary to expectations, the VPS treatment enhanced the development of large intestinal tumors induced by 1,2-DMH in animals sacrificed at 35 weeks after the first injection of the carcinogen.

A survey of entodiniomorphid ciliates in chimpanzees and bonobos.

Intestinal entodiniomorphid ciliates are commonly diagnosed in the feces of wild apes of the genera Pan and Gorilla. Although some authors previously considered entodiniomorphid ciliates as possible pathogens, a symbiotic function within the intestinal ecosystem and their participation in fiber fermentation has been proposed. Previous studies have suggested that these ciliates gradually disappear under captive conditions. We studied entodiniomorphid ciliates in 23 captive groups of chimpanzees, three groups of captive bonobos and six populations of wild chimpanzees. Fecal samples were examined using Sheather's flotation and Merthiolate-Iodine-Formaldehyde Concentration (MIFC) methods. We quantified the number of ciliates per gram of feces. The MIFC method was more sensitive for ciliate detection than the flotation method. Ciliates of genus Troglodytella were detected in 13 groups of captive chimpanzees, two groups of bonobos and in all wild chimpanzee populations studied. The absence of entodiniomorphids in some captive groups might be because of the extensive administration of chemotherapeutics in the past or a side-effect of the causative or prophylactic administration of antiparasitic or antibiotic drugs. The infection intensities of ciliates in captive chimpanzees were higher than in wild ones. We suppose that the over-supply of starch, typical in captive primate diets, might induce an increase in the number of ciliates. In vitro studies on metabolism and biochemical activities of entodiniomorphids are needed to clarify their role in ape digestion.

[Clinical and epidemiological characteristics of blastocystis hominis].

Blastocystis hominis is an intestinal parasite known since long. It is cosmopolitan and lives in the colon. It is still the subject of controversy regarding its pathogenicity and possibly opportunistic character. We exhibit in this article the results obtained for 4 years on the epidemiological, clinical and biological character and opportunistic Blastocystis hominis, often overlooked in the examination of parasitological laboratories city. This is a retrospective study of 3257 stool examination (PSE), performed in the Mycology Laboratory of Parasitology of the Charles Nicolle Hospital in Tunis over a period of 4 years (January 2005-December 2008). Detection of Blastocystis hominis has been made by microscopic examination of samples by direct examination and concentration. Blastocystis was found in 7.27% of cases and 48.5% in men. Endolimax nanus is the parasite most frequently associated with Blastocystis (40.4% of cases). The port was symptomatic in 72.1% of cases, diarrhea is the symptom most often found (27.7%). There is a seasonal distribution; in fact, it is more frequently diagnosed in summer and autumn. The absence of gravity and the saprophytic nature of this infection do not lead to an indication for treatment even among profoundly immunosuppressed individuals. Only the persistence of clinical disorders associated with the detection of the parasite and in the absence of other micro-organisms and intestinal parasites justifies the treatement. Metronidazole is the molecule used conventionally.

Small bowel (SB) capsule endoscopy (CE) studies provide data on both gastric and SB transit times (GTT and SBTT, respectively). This study aimed to evaluate the influence of demographic and clinical parameters on the GTT and SBTT. Transit times for two generations of capsules (Pillcam SB2 and SB3) were also compared. Consecutive adult patients undergoing CE were included. GTT, SBTT, and cecum arrival rates were calculated and correlated to demographics and clinical characteristics. A total of 332 CE studies were analyzed. Neither GTT nor SBTT were impacted by age or sex. SBTT was prolonged in newly diagnosed Crohn's disease (CD) patients compared with all other patients (303.1±90.3 vs. 243.6±83.6 min, P=0.02 for SB2, 267.8±63 vs. 228.6±72.3, P=0.01 for SB3, respectively). Moreover, CD patients had higher incomplete study rates compared with patients with all other diagnoses (29.4 vs. 7.3%, respectively, P=0.0116) in the SB2 subgroup. Higher cecum arrival rates were achieved by the SB3 capsule compared with SB2 (97 vs. 91%, P=0.04). Patients with prolonged gastric time or patients with incomplete studies had similar demographic and clinical characteristics as others. Age and sex apparently do not influence intestinal kinetics. Newly diagnosed CD patients have relatively prolonged SBTTs. Demographic and clinical parameters cannot predict prolonged GTT or cecum nonarrival.

Abstract Background Strongyloides stercoralis is one of the most neglected tropical diseases. Sparse, dated central African and Rwandan data on seroprevalence are available to guide public health efforts and clinical care. Methods In February 2016 we conducted a community-based cross-sectional study among 539 asymptomatic participants in a rural area in the Gisagara District, Southern Province, Rwanda. Direct faecal smear (DFS) and modified Koga agar plate culture (APC) were used to detect S. stercoralis infection in a single stool sample. Data on other soil-transmitted helminths diagnosed by DFS were also recorded. Results Four intestinal helminth infections were diagnosed, with S. stercoralis (17.4%) and hookworms (8.2%) seen most often. APC, compared with DFS, increased the diagnosis rate for S. stercoralis from 1.9% to 17.4% (p<0.01). The prevalence was higher in farmers and those with lower socio-economic status. Females were less often infected than males (odds ratio 0.6 [95% confidence interval 0.3 to 0.9], p=0.02). Conclusions S. stercoralis is highly prevalent among the general population in a rural area of Gisagara District, Southern Province, Rwanda. Access to effective diagnosis and treatment is needed for this neglected disease. PMID:29726969

Physiologically relevant sources of absorptive intestinal epithelial cells are crucial for human drug transport studies. Human adenocarcinoma-derived intestinal cell lines, such as Caco-2, offer conveniences of easy culture maintenance and scalability, but do not fully recapitulate in vivo intestinal phenotypes. Additional sources of renewable physiologically relevant human intestinal cells would provide a much needed tool for drug discovery and intestinal physiology. We compared two alternative sources of human intestinal cells, commercially available primary human intestinal epithelial cells (hInEpCs) and induced pluripotent stem cell (iPSC)-derived intestinal cells to Caco-2, for use in in vitro transwell monolayer intestinal transport assays. To achieve this for iPSC-derived cells, intestinal organogenesis was adapted to transwell differentiation. Intestinal cells were assessed by marker expression through immunocytochemical and mRNA expression analyses, monolayer integrity through Transepithelial Electrical Resistance (TEER) measurements and molecule permeability, and functionality by taking advantage the well-characterized intestinal transport mechanisms. In most cases, marker expression for primary hInEpCs and iPSC-derived cells appeared to be as good as or better than Caco-2. Furthermore, transwell monolayers exhibited high TEER with low permeability. Primary hInEpCs showed molecule efflux indicative of P-glycoprotein (Pgp) transport. Primary hInEpCs and iPSC-derived cells also showed neonatal Fc receptor-dependent binding of immunoglobulin G variants. Primary hInEpCs and iPSC-derived intestinal cells exhibit expected marker expression and demonstrate basic functional monolayer formation, similar to or better than Caco-2. These cells could offer an alternative source of human intestinal cells for understanding normal intestinal epithelial physiology and drug transport. PMID:23847534

Taenia solium-taeniasis and cysticercosis were studied in the human and porcine populations of a rural community in the Southern Ecuadorian Andes. From the 1059 inhabitants, 800 serum samples and 958 stool samples could be collected. In addition, 646 from the estimated 1148 pigs were tongue inspected. Circulating antigen was detected by enzyme linked immunosorbent assay (Ag-ELISA) in 2.25% of the human population, whereas intestinal taeniasis was detected in 1.46% by the formalin-ether technique. Following treatment and recovery of tapeworm fragments these were all identified as T. solium. Porcine cysticercosis was diagnosed in 3.56% of the pigs by tongue inspection. In addition, enzyme linked immunoelectrotransfer blot (EITB) was performed on a subset group of 100 humans to confirm the results of the Ag-ELISA. One hundred serum samples from pigs were also analysed by EITB. It appeared that 43 and 74% of humans and pigs had antibodies against T. solium cysticerci, respectively. It is concluded that contrary to the high exposure of the human population to T. solium that is suggested by EITB, the number of active cysticercosis cases, diagnosed by Ag-ELISA, was low, which may indicate endemic stability. The further use of complementary diagnostic methods for a better understanding of the epidemiology of T. solium is suggested.

Objective To report the clinical presentation and oncologic outcomes of a series of patients who presented with an abdominal or pelvic mass and were diagnosed with a gastrointestinal stromal tumor (GIST). Methods Data were obtained on all patients who presented with an abdominal or pelvic mass between September 2007 and June 2010 and who were ultimately diagnosed with a GIST. The patients' medical records were reviewed. A literature review was also conducted. Results Six patients were identified who met the inclusion criteria. All six patients had a tumor in the intestinal tract arising from the small bowel. The mean tumor size was 12 cm (range, 6 to 22 cm). A complete resection was achieved in five of the six patients. There were no intraoperative complications; one patient had a postoperative complication. Two patients were treated with imatinib after surgery. The mean follow-up time was 32 months (range, 0.3 to 40 months). At the last follow-up, five of the six patients were without any evidence of disease. One patient died of an unrelated hepatic encephalopathy. The incidence in our institution is 3%. Conclusion GISTs are uncommon; however, they should be considered in the differential diagnosis of patients presenting with an abdominal or pelvic mass. PMID:22355467

Mortality from radical cystectomy is still high, in some series accounting for 1-10% deaths. Morbidity is even higher and can reach 50%. This paper contributes the case of a 66-year old male patient diagnosed with an infiltrant tumour of the bladder following TUR. The patient's background included prior surgery for gastroduodenal ulcus, alcohol consumption, and obesity. Following routine pre-operatory investigations, the patient underwent radical cystectomy using routine techniques and urinary by-pass via transcolonic ureterosigmoidostomy. Increased transaminases, leucocytosis, vomiting, jaundice and extended intestinal ileum were noted during the patient's post-operative period, while blood and urine amylase concentrations were moderately high. Following CAT study, laparotomy was performed and the diagnosed confirmed. The patient died on day 14 of surgery due to secondary pulmonary complications. Post-operative pancreatitis is a low-frequency, high-mortality acknowledged complication. Even though most cases are secondary to biliarypancreatic and surrounding pancreas area surgery, it has also been described in some instances of distant surgery such as the present case. Alcohol consumption, biliary lithiasis, prior cholecystectomy and diabetes are predisposing factors. High amylase values do not always accompany this condition. Early diagnosis and treatment are crucial for the patient's prognosis. Respiratory complications are the usual cause of death in these patients.

The aim of this study was to compare the significance of the intestinal hydrolysis of prenylated flavonoids in Herba Epimedii by an intestinal enzyme and flora. Flavonoids were incubated at 37 °C with rat intestinal enzyme and intestinal flora. HPLC-UV was used to calculate the metabolic rates of the parent drug in the incubation and LC/MS/MS was used to determine the chemical structures of metabolites generated by different flavonoid glycosides. Rates of flavonoid metabolism by rat intestinal enzyme were quicker than those of intestinal flora. The sequence of intestinal flora metabolic rates was icariin>epimedin B>epimedin A>epimedin C>baohuoside I, whereas the order of intestinal enzyme metabolic rates was icariin>epimedin A>epimedin C>epimedin B>baohuoside I. Meanwhile, the LC/MS/MS graphs showed that icariin produced three products, epimedin A/B/C had four and baohuoside I yielded one product in incubations of both intestinal enzyme and flora, which were more than the results of HPLC-UV due to the fact LC/MS/MS has lower detectability and higher sensitivity. Moreover, the outcomes indicated that the rate of metabolization of flavonoids by intestinal enzyme were faster than those of intestinal flora, which was consistent with the HPLC-UV results. In conclusion, the metabolic pathways of the same components by intestinal flora and enzyme were the same. What's more, an intestinal enzyme such as lactase phlorizin hydrolase exhibited a more significant metabolic role in prenylated flavonoids of Herba Epimedi compared with intestinal flora.

BACKGROUND Intestinal lymphangiectasia (IL) is a rare disease characterized by a dilatation of the intestinal lymphatics and loss of lymph fluid into the gastrointestinal tract leading to hypoproteinemia, edema, lymphocytopenia, hypogammaglobinemia, and immunological abnormalities. Iron, calcium, and other serum components (e.g., lipids, fat soluble vitamins) may also be depleted. A literature search revealed more than 200 reported cases of IL. Herein, we report our observations of a patient diagnosed with IL; we also present our conclusion for our review of the published literature. CASE REPORT A 24-year-old male was admitted to Aleppo University Hospital with the complaints of abdominal pain, headache, arthralgia, fever, and rigors. His past medical history was remarkable for frequent episodes of diarrhea, recurrent infections, and swelling in the lower limbs. In addition, he had been hospitalized several times in non-academic hospitals due to edema in his legs, cellulitis, and recurrent infections. In the emergency department, a physical examination revealed a patient in distress. He was weak, dehydrated, pale, and had a high-grade fever. His lower extremities were edematous, swollen, and extremely tender to touch. The overlying skin was erythematous and warm. Moreover, the patient was tachycardic, tacypneic, and moderately hypotensive. The patient was resuscitated with IV fluids, and Tylenol was administered to bring the temperature down. Blood tests showed anemia and high levels of inflammatory markers. The patient's white blood cell count was elevated with an obvious left shift. However, subsequent investigations showed that the patient had IL. Suitable diet modification plans were applied as a long-term management plan. CONCLUSIONS IL is a rare disease of challenging nature due to its systematic effects and lack of comprehensive studies that can evaluate the effectiveness of specific treatments in a large cohort of patients. MCT (medium-chain triglyceride) oils and diet modification strategies are effective in reducing the loss of body proteins and in maintaining near-normal blood levels of immunoglobulins. However, octreotide and MCT oils had no proven role in shrinking edema in our patient.

To analyze small intestinal bacterial overgrowth in school-aged children and the relationship between hydrogen and methane production in breath tests. This transversal study included 85 children residing in a slum and 43 children from a private school, all aged between 6 and 10 years, in Osasco, Brazil. For characterization of the groups, data regarding the socioeconomic status and basic housing sanitary conditions were collected. Anthropometric data was obtained in children from both groups. All children completed the hydrogen (H(2)) and methane (CH(4)) breath test in order to assess small intestinal bacterial overgrowth (SIBO). SIBO was diagnosed when there was an increase in H(2) ≥ 20 ppm or CH(4) ≥ 10 ppm with regard to the fasting value until 60 min after lactulose ingestion. Children from the slum group had worse living conditions and lower nutritional indices than children from the private school. SIBO was found in 30.9% (26/84) of the children from the slum group and in 2.4% (1/41) from the private school group (P = 0.0007). Greater hydrogen production in the small intestine was observed in children from the slum group when compared to children from the private school (P = 0.007). A higher concentration of hydrogen in the small intestine (P < 0.001) and in the colon (P < 0.001) was observed among the children from the slum group with SIBO when compared to children from the slum group without SIBO. Methane production was observed in 63.1% (53/84) of the children from the slum group and in 19.5% (8/41) of the children from the private school group (P < 0.0001). Methane production was observed in 38/58 (65.5%) of the children without SIBO and in 15/26 (57.7%) of the children with SIBO from the slum. Colonic production of hydrogen was lower in methane-producing children (P = 0.017). Children who live in inadequate environmental conditions are at risk of bacterial overgrowth and methane production. Hydrogen is a substrate for methane production in the colon.

Combination of a poxvirus-based vaccine with a cyclooxygenase-2 inhibitor (celecoxib) elicits antitumor immunity and long-term survival in CEA.Tg/MIN mice.

The present study was designed to determine whether: (a) chronic administration of dietary celecoxib (Celebrex), a potent nonsteroidal anti-inflammatory drug, which targets the cyclooxygenase-2 (COX-2) enzyme, negatively impacts host immunity; and (b) celecoxib can be coupled with a poxvirus-based vaccine to impact tumor burden in a murine tumor model of spontaneous adenomatous polyposis coli. Naive mice fed the celecoxib-supplemented diets developed eosinophilia with lowered plasma prostaglandin E(2) levels and reduced COX-2 mRNA expression levels in their splenic T cells. Responses of splenic T, B, and natural killer cells to broad-based and antigen-specific stimuli were, for the most part, unchanged in those mice as well as COX-2 knockout mice; exceptions included: (a) reduced IFN-gamma production by concanavalin A- or antigen-stimulated T cells; and (b) heightened lipopolysaccharide response of naive B cells from mice fed a diet supplemented with 1000 ppm of celecoxib. When transgenic mice that express the human carcinoembryonic antigen (CEA) gene (CEA transgenic) were bred with mice bearing a mutation in the Apc(Delta850) gene (multiple intestinal neoplasia mice), the progeny (CEA transgenic/multiple intestinal neoplasia) spontaneously develop multiple intestinal neoplasms that overexpress CEA and COX-2. Beginning at 30 days of age, the administration of a diversified prime/boost recombinant CEA-poxvirus-based vaccine regimen or celecoxib (1000 ppm)-supplemented diet reduced the number of intestinal neoplasms by 54% and 65%, respectively. Combining the CEA-based vaccine with the celecoxib-supplemented diet reduced tumor burden by 95% and significantly improved overall long-term survival. Both tumor reduction and improved overall survival were achieved without any evidence of autoimmunity directed at CEA-expressing or other normal tissues. Celecoxib is prescribed for the treatment of familial adenomatous polyposis in humans, and the CEA-based vaccines have been well tolerated and capable of eliciting anti-CEA host immune responses in early clinical studies. The results suggest that the administration of a recombinant poxvirus-based vaccine is compatible with celecoxib, and this combined chemoimmuno-based approach might lead to an additive therapeutic antitumor benefit not only in patients diagnosed with familial adenomatous polyposis but, perhaps, in other preventive settings in which COX-2 overexpression is associated with progression from premalignancy to neoplasia.

Celiac disease is a chronic small intestinal inflammatory disorder mediated by an immune response to gluten peptides in genetically susceptible individuals. Celiac disease is often diagnosed in early childhood, but some patients receive a diagnosis late in life. It is uncertain whether pediatric celiac disease is distinct from adult celiac disease. It has been proposed that gluten-reactive T cells in children recognize deamidated and native gluten epitopes, whereas T cells from adults only recognize deamidated gluten peptides. We studied the repertoire of gluten epitopes recognized by T cells from children and adults. We examined T-cell responses against gluten by generating T-cell lines and T-cell clones from intestinal biopsies of adults and children and tested proliferative response to various gluten peptides. We analyzed T cells from 14 children (2-5 years old) at high risk for celiac disease who were followed for celiac disease development. We also analyzed T cells from 6 adults (26-55 years old) with untreated celiac disease. All children and adults were positive for HLA-DQ2.5. Biopsies were incubated with gluten digested with chymotrypsin (modified or unmodified by the enzyme transglutaminase 2) or the peptic-tryptic digest of gliadin (in native and deamidated forms) before T-cell collection. Levels of T-cell responses were higher to deamidated gluten than to native gluten in children and adults. T cells from children and adults each reacted to multiple gluten epitopes. Several T-cell clones were cross-reactive, especially clones that recognized epitopes from γ-and ω-gliadin. About half of the generated T-cell clones from children and adults reacted to unknown epitopes. T-cell responses to different gluten peptides appear to be similar between adults and children at the time of diagnosis of celiac disease. Copyright © 2017 AGA Institute. Published by Elsevier Inc.

An 8-yr-old intact female African lion (Panthera leo) presented with a 3-day history of lethargy, anorexia, and vomiting. Hematologic and biochemical abnormalities included a leukocytosis, 41,700/microl (4,700-15,300) with a neutrophilia (37,530/microl; 2,000-9,200) and a left shift (1,250/microl bands; 0-300), and mild hypokalemia of 2.1 mEq/L (2.8-4.8). Abdominal radiographs revealed evidence of intestinal ileus, peritonitis, and the presence of effusion. An exploratory laparotomy was performed, and septic peritonitis due to a pyometra was diagnosed. The lion was treated with an ovariohysterectomy, abdominal lavage, fluid therapy, and a subcutaneous injection of cefovecin. The lion recovered, and clinical signs associated with septic peritonitis resolved within 36 hr. It was returned to conspecifics 3 wk later. Three months postoperatively, the lion showed no residual signs of septic peritonitis.

Small intestinal biopsy remains the gold standard in diagnosing celiac disease (CD); however, the wide spectrum of histopathological states and differential diagnosis of CD is still a diagnostic problem for pathologists. Recently, Ensari reviewed the literature and proposed an update of the histopathological diagnosis and classification for CD. In this study, the histopathological materials of 54 children in whom CD was diagnosed at our hospital were reviewed to compare the previous Marsh and Modified Marsh-Oberhuber classifications with this new proposal. In this study, we show that the Ensari classification is as accurate as the Marsh and Modified Marsh classifications in describing the consecutive states of mucosal damage seen in CD. Ensari's classification is simple, practical and facilitative in diagnosing and subtyping of mucosal pathology of CD.

When abdominal distention occurs or bowel obstruction is suspected in the neonatal period, a water-soluble contrast enema is helpful for diagnostic and therapeutic purposes. The water-soluble contrast medium is evacuated through the anus as well as excreted via the kidneys in some babies. This study was designed to evaluate the incidence of renal excretion after enemas using water-soluble contrast media and presume the causes. Contrast enemas using diluted water-soluble contrast media were performed in 23 patients under 2 months of age. After the enema, patients were followed with simple abdominal radiographs to assess the improvement in bowel distention, and we could also detect the presence of renal excretion of contrast media on the radiographs. Reviewing the medical records and imaging studies, including enemas and consecutive abdominal radiographs, we evaluated the incidence of renal excretion of water-soluble contrast media and counted the stay duration of contrast media in urinary tract, bladder, and colon. Among 23 patients, 12 patients (52%) experienced the renal excretion of water-soluble contrast media. In these patients, stay-in-bladder durations of contrast media were 1-3 days and stay-in-colon durations of contrast media were 1-10 days, while stay-in-colon durations of contrast media were 1-3 days in the patients not showing renal excretion of contrast media. The Mann-Whitney test for stay-in-colon durations demonstrated the later evacuation of contrast media in the patients with renal excretion of contrast media (p = 0.07). The review of the medical records showed that 19 patients were finally diagnosed as intestinal diseases, including Hirschsprung's disease, meconium ileum, meconium plug syndrome, and small bowel atresia or stenosis. Fisher's exact test between the presence of urinary excretion and intestinal diseases indicated a statistically significant difference (p = 0.04). The intestinal diseases causing bowel obstruction may increase the water-soluble contrast media's dwell time in the bowel and also increase urinary excretion. Copyright © 2013.

Background: The epidemiology of inflammatory bowel disease [IBD] in Eastern Europe is poorly understood, particularly with regard to diagnostic delay. Here we investigated the factors leading to delayed diagnosis and the effect of the delay on several disease progression and outcome measures. Methods: A total of 1196 IBD cases [682 ulcerative colitis [UC], 478 Crohn’s disease [CD], 36 indeterminate colitis] from the Romanian national registry IBDPROSPECT were reviewed. Standard clinical and demographic factors were evaluated as predictors of a long diagnostic delay in both CD and UC. Diagnostic delay was subsequently evaluated as a potential risk factor for bowel stenoses, bowel fistulas, perianal fistulas, perianal surgery, and intestinal surgery in CD patients. Results: The median diagnostic delay was significantly longer in CD [5 months] than in UC [1 month] patients [p < 0.001]. Compared with 5 months for UC patients, 75% of CD patients were diagnosed within 18 months of symptom onset. In CD patients, extra-ileal location was a protective factor (odds ratio [OR], 0.5; p = 0.03), whereas being an active smoker [OR, 2.09; p = 0.01] and symptom onset during summer [OR, 3.35; p < 0.001] were independent risk factors for a long diagnostic delay [> 18 months]. In UC patients, an age > 40 years was a protective factor [OR, 0.68; p = 0.04] for a long delay. Regarding outcomes, a long diagnostic delay in CD patients positively correlated with bowel stenoses [OR, 3.38; p < 0.01] and any IBD-related surgery [OR, 1.95; p = 0.03] and had a positive trend for intestinal fistulas [OR, 2.64; p = 0.08] and perianal fistulas [OR, 2.9; p = 0.07]. Disease duration since diagnosis positively correlated with bowel stenoses [OR, 1.04; p = 0.04], any IBD-related surgery [OR, 1.04; p = 0.02], and intestinal surgery [OR, 1.07; p < 0.01]. Conclusions: A long diagnostic delay in IBD correlates with an increased frequency of bowel stenoses and need for IBD-related surgery. PMID:26589956

Intestinal occlusion due to intussusception produced by intestinal tumors is a very rare condition. Gastrointestinal stromal tumors are also rare digestive neopasias, with an impredictable malignant behavior, which are usually growing outside the intestinal wall, being rarely the initiators of an intestinal intussusception. We present the case of a 59 years old female, admitted in our hospital to elucidate the etiology of her iron deficient anaemia, which developed an intestinal occlusion at the intestinal preparation for colonoscopy. The abdominal CT scan performed in emergency conditions highlighted occlusive intestinal tumor complicated with intestinal intussusception. We performed an emergency laparotomy that revealed intestinal occlusion due to ileo-ileal intussusception produced by an ileal tumor. The surgical intervention consisted in segmental ileal enterectomy including the tumor with latero-lateral entero-enteral anastomosis. The patient recovered without complications. The histopathological and immunohisto-chemical examinations established the diagnose of gastro-intestinal stromal tumor with high risk malignant behavior, therefore the patient was guided in the oncological department for specific treatment and oncological surveillance.

It may serve as the prodrug and be converted into the active forms in gastrointestinal tract, which mainly occurred in intestinal tract composed of intestinal bacteria and intestinal enzyme. Intestinal bacteria, a new drug target, take a significant role on exerting pharmacological effects of drugs by oral administration. In this paper, acteoside was incubated with human or rat intestinal bacteria or rat intestinal enzyme for 36 h to seek metabolites responsible for pharmacodynamics. The samples were analyzed by ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry. Besides the parent compound, 14 metabolites were detected and identified based on their retention times and fragmentation patterns in their MS spectra including 8 degradation metabolites, 2 isomers in intestinal bacteria and intestinal enzyme samples and 4 parent metabolites only found in intestinal enzymes. The metabolic pathway of acteoside was thus proposed. Identification of these metabolites of acteoside by the intestinal bacteria or intestinal enzyme gave an insight to clarify pharmacological mechanism of traditional Chinese medicines and identify the real active molecules.

Previously reported cases of botulism in infants have been diagnosed as infant botulism; that is, botulism caused by intestinal colonization by Clostridium botulinum with intraluminal production and absorption of toxin. Foodborne botulism is caused by ingestion of preformed toxin. We describe an unusual case of foodborne botulism in a 6-month-old infant caused by the ingestion of improperly prepared home-canned baby food. This represents the youngest age of onset for foodborne botulism in the United States of which we are aware and illustrates the need to rule out foodborne botulism, which represents a public health emergency, regardless of the patient's age. The diagnosis could have been readily missed or delayed in this case because the weakness was rapidly progressive rather than insidious, as is typical of infant botulism.

Hepatic toxocariasis: a rare cause of right upper abdominal pain in the emergency department.

Toxocara canis and Toxocara cati are common helminths that reside in the intestinal tract of cats and dogs. Toxocariasis and, commonly, T. canis, is a disease commonly seen in children, which is characterised by hypereosinophilia, hepatomegaly, fever, transient pulmonary infiltration, and hypergammaglobulinaemia. Humans, who are not the actual host for these parasitic worms, are infected following oral intake of the infective eggs. Radiological differentiation of hepatic toxocariasis can be difficult, as liver lesions, which present as multiple hypoechoic lesions with regular borders, can look like a tumour, an infarction or an infection. We report on a case that presented to our emergency department (ED) with abdominal pain. During the initial review, the pathology in the liver was thought to be an infarction or an infection; however, the patient was diagnosed with hepatic toxocariasis following further evaluation.

We examined 10 common eider (Somateria mollissima) males found dead in 1998 during a die-off in the northern Baltic Sea off the southwestern coast of Finland. We diagnosed impaction of the posterior small intestine with mucosal necrosis as the cause of death in all 10 and isolated adenoviruses from cloacal samples of six birds. The adenovirus isolates were not neutralized by reference antisera to group I, II, or III avian adenoviruses. Cloacal swabs from 22 apparently healthy eider females nesting at the mortality area were negative for viruses. An adenovirus isolated from one of the eiders caused clinical signs of illness and gastrointestinal pathology in experimentally infected mallard (Anas platyrhynchos) ducklings. These findings suggest that the adenovirus contributed to the mortality of common eider males in the Finnish archipelago.

Worldwide an estimated 1.5-2 billion people are infested with helminths. Over the last decades, in industrialized countries prevalence rates of human helminthic infections were decreased by means of wastewater and food control. In this article, we review the geographic distributions as well as the impact on the public health system of the most prevalent helminthiases. Special emphasis is given to Echinococcus, Enterobiasis, and Toxocariasis. Intestinal larvae or eggs of helminths can be detected in faeces. Pinworms are collected with a strip of cellophane tape with the sticky side towards the anus. Tissue helminthosis, like Toxocariasis or Trichinosis are associated with eosinophilia and can be diagnosed with sensitive immunological methods or by biopsy. Infection with Echinococcus multilocularis is the most serious parasitic disease in central Europe. Although current therapeutic options are limited, 5 year survival rates were markedly improved by the combination of medical and surgical treatment.

Guillain-Barré syndrome during adalimumab therapy for Crohn´s disease: coincidence or consequence?

We report the case of a 64-year-old patient diagnosed with extensive ileal Crohn´s disease who developed Guillain-Barré syndrome after starting biological therapy with adalimumab. Neurologic involvement associated with inflammatory bowel diseases is recognized as an extra-intestinal manifestation. After the breakthrough of antitumor necrosis factor alpha (anti-TNF-α) agents, an increasing number of cases of acute inflammatory demyelinating polyneuropathies have been reported; however, only one case has been described in a patient with Crohn´s disease. Although a causal relationship between Guillain-Barré syndrome and TNF-α antagonist therapy cannot be proven, this report emphasizes the need to monitor for neurologic signs and symptoms in patients with inflammatory bowel diseases, with or without biological therapy, to avoid severe and irreversible complications associated with demyelinating diseases.

A 66-year-old man presented at our emergency department with severe intermittent abdominal pain. His history revealed that he had eaten several mochi (rice cakes) without sufficiently chewing them before swallowing. Following computed tomography that showed a high value, he was diagnosed with an obstruction caused by mochi. Although mochi obstruction can sometimes improve with conservative treatment, this case required laparotomy. Medical literature in English on small bowel obstruction due to mochi is rare, but fortunately in this case we were able to collect complete laboratory and imaging data. Furthermore, due to the surgical findings, we could clearly diagnose the pathophysiology of mochi obstruction. Here we describe a case of small bowel obstruction due to mochi, and review the literature to determine the characteristics of intestinal obstruction caused by it.

An 18-yr-old female Western lowland gorilla ( Gorilla gorilla gorilla) presented with acute-onset severe lethargy, bloody vaginal discharge, decreased appetite, and an abnormal posture. The gorilla was diagnosed with a ruptured cecal blind sac with severe adhesions to the right ovary. A typhlectomy and unilateral ovariectomy were performed. Histologic examination identified a severe transmural circumferential typhlitis with rupture and adhesions to the infundibulum and chronic typhlitis. Postoperative management included antibiotics, analgesics, short-term dietary modifications, and probiotics for suspect oral candidiasis. The gorilla made a full clinical recovery and was pregnant within 1 yr of surgery. To the authors' knowledge, this is the first case of successful management of typhlitis in a gorilla. Typhlitis and intestinal rupture should be considered as a differential diagnosis for acute onset severe abdominal pain in gorillas.

Peritoneal air exposure is needed in open abdominal surgery, but long-time exposure could induce intestinal mucosal barrier dysfunction followed by many postoperative complications. High-fat enteral nutrition can ameliorate intestinal injury and improve intestinal function in many gastrointestinal diseases. In the present study, we investigated the effect of high-fat enteral nutrition on intestinal mucosal barrier after peritoneal air exposure and the underlying mechanism. Male adult rats were administrated saline, low-fat or high-fat enteral nutrition via gavage before and after peritoneal air exposure for 3 h. Rats undergoing anesthesia without laparotomy received saline as control. Twenty four hours after surgery, samples were collected to assess intestinal mucosal barrier changes in serum D-lactate levels, intestinal permeability, intestinal tight junction protein ZO-1 and occludin levels, and intestinal histopathology. The levels of malondialdehyde and the activity of superoxide dismutase in the ileum tissue were also measured to assess the status of intestinal oxidative stress. High-fat enteral nutrition significantly decreased the serum D-lactate level and increased the intestinal tight junction protein ZO-1 level when compared to the group treated with low-fat enteral nutrition (P < 0.05). Meanwhile, histopathologic findings showed that the intestinal mucosal injury assessed by the Chiu's score and the intestinal epithelial tight junction were also improved much more in the high-fat enteral nutrition-treated group (P < 0.05). In addition, the intestinal malondialdehyde level was lower, and the intestinal superoxide dismutase activity was higher in the high-fat enteral nutrition-treated group than that in the low-fat enteral nutrition-treated group (P < 0.05). These results suggest that high-fat enteral nutrition could reduce intestinal mucosal barrier damage after peritoneal air exposure, and the underlying mechanism may be associated with its antioxidative action. Perioperative administration of high-fat enteral nutrition may be a promising intervention to preserve intestinal mucosal barrier function in open abdominal surgery. Copyright © 2016 Elsevier Inc.

Zinc transporters play a critical role in spatiotemporal regulation of zinc homeostasis. Although disruption of zinc homeostasis has been implicated in disorders such as intestinal inflammation and aberrant epithelial morphology, it is largely unknown which zinc transporters are responsible for the intestinal epithelial homeostasis. Here, we show that Zrt-Irt-like protein (ZIP) transporter ZIP7, which is highly expressed in the intestinal crypt, is essential for intestinal epithelial proliferation. Mice lacking Zip7 in intestinal epithelium triggered endoplasmic reticulum (ER) stress in proliferative progenitor cells, leading to significant cell death of progenitor cells. Zip7 deficiency led to the loss of Olfm4+ intestinal stem cells and the degeneration of post-mitotic Paneth cells, indicating a fundamental requirement for Zip7 in homeostatic intestinal regeneration. Taken together, these findings provide evidence for the importance of ZIP7 in maintenance of intestinal epithelial homeostasis through the regulation of ER function in proliferative progenitor cells and maintenance of intestinal stem cells. Therapeutic targeting of ZIP7 could lead to effective treatment of gastrointestinal disorders. PMID:27736879

Gastric intestinal metaplasia can display cytoarchitectural atypia that falls short of qualifying for dysplasia but can be classified as indefinite for dysplasia. Yet few studies have evaluated the prevalence, the morphologic, and biologic characteristics of this variant. Out of a cohort of 554 biopsies with chronic atrophic gastritis and/or dysplasia, we categorized the cases as either (1) simple intestinal metaplasia; (2) intestinal metaplasia with hyperplasia; (3) intestinal metaplasia with basal gland atypia; and (4) gastric dysplasia. The relationship between the subtypes and various clinicopathologic features, mucin immunophenotypes, and biologic characteristics was evaluated. The final cohort consisted of 424 cases of simple intestinal metaplasia, 93 intestinal metaplasia with hyperplasia, 16 intestinal metaplasia with basal gland atypia, and 21 gastric dysplasia. Intestinal metaplasia with basal gland atypia had a prevalence of 2.8% and similar to gastric dysplasia, 3.7%. Both of these lesions were similar in body/fundus distribution (12.5%) and paucity of goblet cells (68.8%). Intestinal metaplasia with basal gland atypia and gastric dysplasia seem to share some biologic similarities but with a lower frequency of alpha-methylacyl-CoA racemase expression (25% versus 62%), p53 expression (6.3% versus 47.6%), and increased Ki-67 index on surface/pit and isthmus in intestinal metaplasia with basal gland atypia. Alternatively, simple intestinal metaplasia and intestinal metaplasia with hyperplasia did not differ statistically with regard to the various characteristics evaluated. We concluded that gastric intestinal metaplasia can be divided into 2 broad categories that are readily defined by cytoarchitectural and biologic characteristics. Based on the characteristics of intestinal metaplasia with basal gland atypia and in keeping with others, we confirm that this subtype could represent a preneoplastic lesion that needs further evaluation.

AIM To determine the mechanistic role of fibrinogen, a key regulator of inflammation and fibrosis, in early and delayed radiation enteropathy. METHODS Fibrinogen wild-type (Fib+/+), fibrinogen heterozygous (Fib+/-), and fibrinogen knockout (Fib-/-) mice were exposed to localized intestinal irradiation and assessed for early and delayed structural changes in the intestinal tissue. A 5-cm segment of ileum of mice was exteriorized and exposed to 18.5 Gy of x-irradiation. Intestinal tissue injury was assessed by quantitative histology, morphometry, and immunohistochemistry at 2 wk and 26 wk after radiation. Plasma fibrinogen level was measured by enzyme-linked immunosorbent assay. RESULTS There was no difference between sham-irradiated Fib+/+ and Fib+/- mice in terms of fibrinogen concentration in plasma and intestinal tissue, intestinal histology, morphometry, intestinal smooth muscle cell proliferation, and neutrophil infiltration. Therefore, Fib+/- mice were used as littermate controls. Unlike sham-irradiated Fib+/+ and Fib+/- mice, no fibrinogen was detected in the plasma and intestinal tissue of sham-irradiated Fib-/- mice. Moreover, fibrinogen level was not elevated after irradiation in the intestinal tissue of Fib-/- mice, while significant increase in intestinal fibrinogen level was noticed in irradiated Fib+/+ and Fib+/- mice. Importantly, irradiated Fib-/- mice exhibited substantially less overall intestinal structural injury (RIS, P = 0.000002), intestinal wall thickness (P = 0.003), intestinal serosal thickness (P = 0.009), collagen deposition (P = 0.01), TGF-β immunoreactivity (P = 0.03), intestinal smooth muscle proliferation (P = 0.046), neutrophil infiltration (P = 0.01), and intestinal mucosal injury (P = 0.0003), compared to irradiated Fib+/+ and Fib+/- mice at both 2 wk and 26 wk. CONCLUSION These data demonstrate that fibrinogen deficiency directly attenuates development of early and delayed radiation enteropathy. Fibrinogen could be a novel target in treating intestinal damage. PMID:28765691

Prom1/CD133 has been identified in colorectal, hepatocellular, and pancreatic cancer as a cancer stem cell marker and has been used as such to predict colon cancer recurrence in humans. Its potential molecular function as well as its role as a marker of intestinal regeneration is still not fully known. We evaluated the role of Prom1 in intestinal regeneration in inflammatory bowel disease (IBD), determined the function of Prom1, and characterized the effect of a lack of Prom1 on intestinal tumor formation in animal models. Our results suggest that Apc mutations lead to an increase in Prom1 expressing cells in the intestinal crypt stem cell compartment and in early intestinal adenomas. Also, Prom1 knockout mice are more susceptible to intestinal tumor formation. We conclude that Prom1 likely plays a role in regulating intestinal homeostasis and that these results clearly illustrate the role of Prom1 in intestinal regeneration. We further conclude that Prom1 may provide a novel therapeutic target for patients with gastrointestinal conditions such as IBD, short bowel syndrome, and colorectal cancer. PMID:25452936

Within seven days following peroral high dose infection with Toxoplasma gondii susceptible conventionally colonized mice develop acute ileitis due to an underlying T helper cell (Th) -1 type immunopathology. We here addressed whether mice harboring a human intestinal microbiota developed intestinal, extra-intestinal and systemic sequelae upon ileitis induction. Secondary abiotic mice were generated by broad-spectrum antibiotic treatment and associated with a complex human intestinal microbiota following peroral fecal microbiota transplantation. Within three weeks the human microbiota had stably established in the murine intestinal tract as assessed by quantitative cultural and culture-independent (i.e. molecular 16S rRNA based) methods. At day 7 post infection (p.i.) with 50 cysts of T. gondii strain ME49 by gavage human microbiota associated (hma) mice displayed severe clinical, macroscopic and microscopic sequelae indicating acute ileitis. In diseased hma mice increased numbers of innate and adaptive immune cells within the ileal mucosa and lamina propria and elevated intestinal secretion of pro-inflammatory mediators including IFN-γ, IL-12 and nitric oxide could be observed at day 7 p.i. Ileitis development was accompanied by substantial shifts in intestinal microbiota composition of hma mice characterized by elevated total bacterial loads and increased numbers of intestinal Gram-negative commensals such as enterobacteria and Bacteroides / Prevotella species overgrowing the small and large intestinal lumen. Furthermore, viable bacteria translocated from the inflamed ileum to extra-intestinal including systemic compartments. Notably, pro-inflammatory immune responses were not restricted to the intestinal tract as indicated by increased pro-inflammatory cytokine secretion in extra-intestinal (i.e. liver and kidney) and systemic compartments including spleen and serum. With respect to the intestinal microbiota composition "humanized" mice display acute ileitis following peroral high dose T. gondii infection. Thus, hma mice constitute a suitable model to further dissect the interactions between pathogens, human microbiota and vertebrate host immunity during acute intestinal inflammation.

Radiation-induced enteritis is a major side effect in cancer patients undergoing abdominopelvic radiotherapy. Radiation exposure produces an uncontrolled inflammatory cascade and epithelial cell loss leading to impaired epithelial barrier function. The goal of this study was to determine the effect of rebamipide on regeneration of the intestinal epithelia after radiation injury. The abdomens of C57BL/6 mice were exposed to 13Gy of irradiation (IR) and then the mice were treated with rebamipide. Upon IR, intestinal epithelia were destroyed structurally at the microscopic level and bacterial translocation was increased. The intestinal damage reached a maximum level on day 6 post-IR and intestinal regeneration occurred thereafter. We found that rebamipide significantly ameliorated radiation-induced intestinal injury. In mice treated with rebamipide after IR, intestinal barrier function recovered and expression of the tight junction components of the intestinal barrier were upregulated. Rebamipide administration reduced radiation-induced intestinal mucosal injury. The levels of proinflammatory cytokines and matrix metallopeptidase 9 (MMP9) were significantly reduced upon rebamipide administration. Intestinal cell proliferation and β-catenin expression also increased upon rebamipide administration. These data demonstrate that rebamipide reverses impairment of the intestinal barrier by increasing intestinal cell proliferation and attenuating the inflammatory response by inhibiting MMP9 and proinflammatory cytokine expression in a murine model of radiation-induced enteritis.

[Research progress of relationship between diabetes and intestinal epithelial tight junction barrier and intervetion of berberine].

PubMed

Qin, Xin; Dong, Hui; Lu, Fu-Er

2016-06-01

Intestinal tight junction is an important part of the small intestinal mucosa barrier. It plays a very significant role in maintaining the intestinal mucosal permeability and integrity, preventing the bacterial endotoxin and toxic macromolecular substances into the body so as to keep a stable internal environment. Numerous studies have shown that intestinal mucosal barrier dysfunction is closely related to the development of diabetes. Therefore, protecting intestinal tight junction and maintaining the mucosal barrier have great significance in the prevention and treatment of diabetes. The effect of berberine in diabetes treatment is obvious. However, the pharmacological study found that the bioavailability of berberine is extremely low. Some scholars put forward that the major site of pharmaceutical action of berberine might be in the gut. Studies have shown that berberine could regulate the intestinal flora and intestinal hormone secretion, protect the intestinal barrier, inhibit the absorption of glucose, eliminate the intestinal inflammation and so on. Recently studies have found that the hypoglycemic effect of berberine is likely to relate with the influence on intestinal tight junction and the protection of mucosal barrier. Here is the review about the association between intestinal tight junction barrier dysfunction and diabetes, and the related hypoglycemic mechanism of berberine.

Multifunctional Bioreactor System for Human Intestine Tissues

PubMed Central

2017-01-01

The three-dimensional (3D) cultivation of intestinal cells and tissues in dynamic bioreactor systems to represent in vivo intestinal microenvironments is essential for developing regenerative medicine treatments for intestinal diseases. We have previously developed in vitro human intestinal tissue systems using a 3D porous silk scaffold system with intestinal architectures and topographical features for the adhesion, growth, and differentiation of intestinal cells under static culture conditions. In this study, we designed and fabricated a multifunctional bioreactor system that incorporates pre-epithelialized 3D silk scaffolds in a dynamic culture environment for in vitro engineering of human intestine tissues. The bioreactor system allows for control of oxygen levels in perfusion fluids (aerobic simulated intestinal fluid (SIF), microaerobic SIF, and anaerobic SIF), while ensuring control over the mechanical and chemical microenvironments present in native human intestines. The bioreactor system also enables 3D cell culture with spatial separation and cultivation of cocultured epithelial and stromal cells. Preliminary functional analysis of tissues housed in the bioreactor demonstrated that the 3D tissue constructs survived and maintained typical phenotypes of intestinal epithelium, including epithelial tight junction formation, intestinal biomarker expression, microvilli formation, and mucus secretion. The unique combination of a dynamic bioreactor and 3D intestinal constructs offers utility for engineering human intestinal tissues for the study of intestinal diseases and discovery options for new treatments.

Introduction Pneumatosis coli is a rare disease with heterogeneous symptoms which can be detected in the course of various acute and chronic intestinal diseases in children, such as necrotizing enterocolitis, intestinal obstruction and intestinal bacteriological infections. Case presentation We report the case of a 12-month-old boy who died of pneumatosis coli caused by an acute intestinal gas gangrene after prolonged artificial alimentation. Conclusion While intestinal gas gangrene is a highly uncommon cause of pneumatosis coli, it is important to consider it as a differential diagnosis, especially in patients receiving a prolonged artificial food supply. These patients may develop intestinal gas gangrene due to a dysfunctional intestinal barrier. PMID:18652650

The magnitude, temporal dynamics, and physiological effects of intestinal microbiome responses to physiological stress are poorly characterized. This study used a systems biology approach and a multiple-stressor military training environment to determine the effects of physiological stress on intestinal microbiota composition and metabolic activity, as well as intestinal permeability (IP). Soldiers ( n = 73) were provided three rations per day with or without protein- or carbohydrate-based supplements during a 4-day cross-country ski-march (STRESS). IP was measured before and during STRESS. Blood and stool samples were collected before and after STRESS to measure inflammation, stool microbiota, and stool and plasma global metabolite profiles. IP increased 62 ± 57% (mean ± SD, P < 0.001) during STRESS independent of diet group and was associated with increased inflammation. Intestinal microbiota responses were characterized by increased α-diversity and changes in the relative abundance of >50% of identified genera, including increased abundance of less dominant taxa at the expense of more dominant taxa such as Bacteroides Changes in intestinal microbiota composition were linked to 23% of metabolites that were significantly altered in stool after STRESS. Together, pre-STRESS Actinobacteria relative abundance and changes in serum IL-6 and stool cysteine concentrations accounted for 84% of the variability in the change in IP. Findings demonstrate that a multiple-stressor military training environment induced increases in IP that were associated with alterations in markers of inflammation and with intestinal microbiota composition and metabolism. Associations between IP, the pre-STRESS microbiota, and microbiota metabolites suggest that targeting the intestinal microbiota could provide novel strategies for preserving IP during physiological stress. NEW & NOTEWORTHY Military training, a unique model for studying temporal dynamics of intestinal barrier and intestinal microbiota responses to stress, resulted in increased intestinal permeability concomitant with changes in intestinal microbiota composition and metabolism. Prestress intestinal microbiota composition and changes in fecal concentrations of metabolites linked to the microbiota were associated with increased intestinal permeability. Findings suggest that targeting the intestinal microbiota could provide novel strategies for mitigating increases in intestinal permeability during stress.

Intestinal necrosis is the most serious complication of intussusception. The risk factors associated with intestinal necrosis in pediatric patients with intussusception have not been well characterized. This study aimed to investigate the risk factors associated with intestinal necrosis in pediatric patients with failed non-surgical reduction for intussusception. Hospitalized patients who failed the air-enema reduction for intussusception in the outpatient department and subsequently underwent surgery were retrospectively reviewed. All cases were categorized into two groups: intestinal necrosis group and non-intestinal necrosis group based on the surgical findings. Demographic and clinical features including the findings from the surgery were recorded and analyzed. Factors associated with intestinal necrosis were analyzed using univariate and multivariate unconditional logistic regression analyses. A total of 728 cases were included. Among them, 171 had intestinal necrosis at the time of surgery. The group with intestinal necrosis had a longer duration of symptom or length of illness (P = 0.000), and younger (P = 0.000) than the non-intestinal necrosis group. Complex/compound type of intussusceptions is more likely to have intestinal necrosis. Multivariate analysis showed that the presence of grossly bloody stool (OR = 2.12; 95% CI 1.19-3.76, P = 0.010) and duration of symptom (OR = 1.07; 95% CI 1.06-1.08, P = 0.000) were independent risk factors for intestinal necrosis in patients hospitalized for surgical reduction for intussusceptions. At time of admission, the presence of bloody stools and duration of symptom are the important risk factors for developing intestinal necrosis for those patients who failed non-surgical reduction. The length of illness has the highest sensitivity and specificity to correlate with intestinal necrosis. This finding may suggest that we should take the intussusception cases that have the longer duration of symptom directly to operation room for reduction.

Recent studies have shown that mast cells play an important role in irritable bowel syndrome (IBS). We investigated the relationship between mast cells and the gut hormones substance P and vasoactive intestinal peptide (VIP) in irritable bowel syndrome with diarrhea (IBS-D). Colonoscopic biopsies were performed on the rectal mucosa of 43 subjects (IBS-D patients: 22, healthy volunteers: 21) diagnosed according to the Rome III criteria. Mast cells, and substance P & VIP were evaluated by quantitative immunohistology and image analysis. Mast cells were counted as tryptase-positive cells in the lamina propria, and substance P and VIP levels were expressed as percentages of total areas of staining. Mast cell counts were higher in IBS-D patients than healthy volunteers (9.6 ± 3.3 vs. 5.7 ± 2.5/high power field (HPF), p < 0.01). Substance P was also elevated (0.11 ± 0.08% vs. 0.03 ± 0.02 %, p < 0.01) while VIP was only high in women with IBS-D. Mast cell counts were positively correlated with levels of substance P & VIP in women but not men (women: r = 0.625, p < 0.01 for substance P and r = 0.651, p < 0.01 for VIP). However, mast cell counts were not correlated with IBS symptoms including abdominal pain. Mast cells are activated leading to the raised levels of substance P & VIP in IBS-D patients. However, the correlation between mast cells and levels of substance P & VIP differs according to gender.

Objective Postoperative ileus (POI), the most frequent complication after intestinal surgery, depends on dendritic cells (DCs) and macrophages. Here, we have investigated the mechanism that activates these cells and the contribution of the intestinal microbiota for POI induction. Design POI was induced by manipulating the intestine of mice, which selectively lack DCs, monocytes or macrophages. The disease severity in the small and large intestine was analysed by determining the distribution of orally applied fluorescein isothiocyanate-dextran and by measuring the excretion time of a retrogradely inserted glass ball. The impact of the microbiota on intestinal peristalsis was evaluated after oral antibiotic treatment. Results We found that Cd11c-Cre+ Irf4flox/flox mice lack CD103+CD11b+ DCs, a DC subset unique to the intestine whose function is poorly understood. Their absence in the intestinal muscularis reduced pathogenic inducible nitric oxide synthase (iNOS) production by monocytes and macrophages and ameliorated POI. Pathogenic iNOS was produced in the jejunum by resident Ly6C– macrophages and infiltrating chemokine receptor 2-dependent Ly6C+ monocytes, but in the colon only by the latter demonstrating differential tolerance mechanisms along the intestinal tract. Consistently, depletion of both cell subsets reduced small intestinal POI, whereas the depletion of Ly6C+ monocytes alone was sufficient to prevent large intestinal POI. The differential role of monocytes and macrophages in small and large intestinal POI suggested a potential role of the intestinal microbiota. Indeed, antibiotic treatment reduced iNOS levels and ameliorated POI. Conclusions Our findings reveal that CD103+CD11b+ DCs and the intestinal microbiome are a prerequisite for the activation of intestinal monocytes and macrophages and for dysregulating intestinal motility in POI.

This report is a summary of the symposium on Alcohol, Intestinal Bacterial Growth, Intestinal Permeability to Endotoxin, and Medical Consequences, organized by National Institute on Alcohol Abuse and Alcoholism, Office of Dietary Supplements, and National Institute of Diabetes and Digestive and Kidney Diseases of National Institutes of Health in Rockville, Maryland, October 11, 2006. Alcohol exposure can promote the growth of Gram negative bacteria in the intestine which may result in accumulation of endotoxin. In addition, alcohol metabolism by Gram negative bacteria and intestinal epithelial cells can result in accumulation of acetaldehyde, which in turn can increase intestinal permeability to endotoxin by increasing tyrosine phosphorylation of tight junction and adherens junction proteins. Alcohol-induced generation of nitric oxide may also contribute to increased permeability to endotoxin by reacting with tubulin, which may cause damage to microtubule cytoskeleton and subsequent disruption of intestinal barrier function. Increased intestinal permeability can lead to increased transfer of endotoxin from the intestine to the liver and general circulation where endotoxin may trigger inflammatory changes in the liver and other organs. Alcohol may also increase intestinal permeability to peptidoglycan which can initiate inflammatory response in liver and other organs. In addition, acute alcohol exposure may potentiate the effect of burn injury on intestinal bacterial growth and permeability. Decreasing the number of Gram negative bacteria in the intestine can result in decreased production of endotoxin as well as acetaldehyde which is expected to decrease intestinal permeability to endotoxin. In addition, intestinal permeability may be preserved by administering epidermal growth factor, L-glutamine, oats supplementation, or zinc thereby preventing the transfer of endotoxin to the general circulation. Thus reducing the number of intestinal Gram negative bacteria and preserving intestinal permeability to endotoxin may attenuate alcoholic liver and other organ injuries. PMID:18504085

[Videocapsule endoscopy as a useful tool to diagnose primary intestinal lymphangiectasia].

Primary intestinal lymphangiectasia (Waldmann's disease) lead to a protein-losing enteropathy due to lymph leak into intestinal tract. A 28-year-old woman presented a bilateral lower limb lymphedema. Laboratory examination showing lymphopenia, hypoalbuminemia, hypogammaglobulinemia suggested the diagnosis of primary intestinal lymphangiectasia. Gastroscopy was normal and second duodenum biopsies were negative. Videocapsule endoscopy gave evidence of intestinal lymphangiectasia of the small bowel. Videocapsule endoscopy may be proposed to confirm intestinal lymphangiectasia and to precise their localization when gastroscopy is not conclusive.

The mammalian intestine must manage to contain 100 trillion intestinal bacteria without inducing inappropriate immune responses to these microorganisms. The effects of the immune system on intestinal microorganisms are numerous and well-characterized, and recent research has determined that the microbiota influences the intestinal immune system as well. In this review, we first discuss the intestinal immune system and its role in containing and maintaining tolerance to commensal organisms. We next introduce a category of immune cells, the innate lymphoid cells, and describe their classification and function in intestinal immunology. Finally, we discuss the effects of the intestinal microbiota on innate lymphoid cells. PMID:24418741

Chronic inflammation and infection are major risk factors for gastric carcinogenesis in adults. As chronic gastritis is common in Mexican children, diagnosis of Helicobacter pylori and other causes of gastritis are critical for the identification of children who would benefit from closer surveillance. Antral biopsies from 82 Mexican children (mean age, 8.3 ± 4.8 years) with chronic gastritis (36 H pylori+, 46 H pylori-) were examined for gastritis activity, atrophy, intestinal metaplasia (IM), and immunohistochemical expression of gastric carcinogenesis biomarkers caudal type homeobox 2 (CDX2), ephrin type-B receptor 4 (EphB4), matrix metalloproteinase 3 (MMP3), macrophage migration inhibitory factor (MIF), p53, β-catenin, and E-cadherin. Atrophy was diagnosed in 7 (9%) of 82, and IM, in 5 (6%) of 82 by routine histology, whereas 6 additional children (7%) (3 H pylori+) exhibited aberrant CDX2 expression without IM. Significant positive correlations were seen between EphB4, MMP3, and MIF (P<.0001). Atrophy and follicular pathology were more frequent in H pylori+ biopsies (P<.0001), whereas IM and CDX2 expression showed no significant correlation with H pylori status. Antral biopsies demonstrating atrophy, IM, and/or aberrant CDX2 expression were seen in 21.95% (18/82) of the children, potentially identifying those who would benefit from closer surveillance and preventive dietary strategies. Biomarkers CDX2, EphB4, MMP3, and MIF may be useful in the workup of pediatric gastritis. Copyright © 2014 Elsevier Inc. All rights reserved.

The designated area of the columnar-lined esophagus (CLE) is anatomically defined by the distal limit of the lower esophageal palisade vessels (LEPV) and the term 'Barrett's esophagus' is equally used along with the name CLE in Japan. The aim of this study was to investigate the actual prevalence of CLE based on the Japanese criteria and to evaluate the criteria per se. A total of 42 esophagi consecutively resected at this institute were included. All subjects underwent a surgical resection for squamous cell carcinoma of the esophagus. The position of the LEPV, squamocolumnar junction, the prevalence of CLE and intestinal metaplasia were investigated both pre- and postoperatively. Preoperative endoscopy revealed CLE based on the Japanese criteria in half of all patients. In the resected specimens the distal limit of LEPV was lower than the squamocolumnar junction in 95.2%. In other words, almost all cases had CLE (equivalent to Barrett's mucosa in Japanese criteria). However, most of the CLE areas were very short and their average maximum length was only about 5 mm. In addition, no intestinal metaplasia was observed in any of the CLE cases. Almost all individuals might therefore be diagnosed to have CLE or Barrett's mucosa based on precise endoscopic observations in Japan. The CLE located in a small area, e.g. less than 5 mm, defined according to the LEPV criteria without any other factor concerning typical Barrett's esophagus such as signs of gastroesophageal reflux should therefore be excluded from consideration as a high-risk mucosa.

This is a report of seven-year-old male Akita mixed dog, with protein-losing enteropathy (PLE). He had a history of chronic vomiting and diarrhea with anorexia/hyporexia. Previously he suffered acute abdomen about eight months prior to this visit. Our dog showed uncommon combination of diseases that could cause PLE since it was affected by inflammatory bowel disease (IBD), intestinal lymphangiectasia (IL), and exocrine pancreatic insufficiency (EPI). The dog had most of the abnormalities found in IL, as well as hypoalbuminemia, hyperglobulinemia, lymphopenia, hypocalcemia, and hypercholesterolemia. During endoscopy exam, we found changes characteristic of IL such as irregular small white spots. We took biopsies from stomach, duodenum, and cecum. These biopsies showed infiltration by lymphocytes and plasmatic cells in the lamina propria also, the duodenal biopsies showed moderate dilation of the lymphatic vessels. The patient had 2.1 µg/mL of TLI, this result was compatible with EPI. We assume that the first pathology in this animal was IBD, which caused chronic pancreatitis (CP) that in turn progressed to EPI. It is also possible that IL was secondary to IBD. We have reported for the first time the correlation of IBD and EPI in dogs. This should change our approach to treating chronic diarrhea in dogs. Therefore, we propose that dogs diagnosed with EPI should also be subjected to endoscopy and intestinal biopsy. Similarly, to rule out secondary EPI, TLI should be measured routinely in dogs with IBD.

Several urethral conditions may require tissue substitution. One collagen-base biomaterial that recently emerged as an option is small intestinal submucosa (SIS). The aim of this study was to compare the results of SIS and buccal mucosa for urethral substitution in rabbits. Thirty-six North Folk male rabbits were randomized into three groups. In all animals, a 10 × 5 mm urethral segment was excised, and the urethral defect was repaired using a one-layer SIS patch (group I [GI]); four-layer SIS (group II [GII]); or buccal mucosa (group III [GIII]). Urethrography was performed preoperatively and after 12 weeks. After sacrifice, graft retraction was objectively measured using Scion Image(®) computer analysis and by calculation of ellipse area. The grade of fibrosis, inflammatory reaction, vascular/epithelial regeneration, and collagen III/I ratio were analyzed by hematoxylin/eosin and Picrosirius red staining. Urethrography confirmed a wide urethral caliber without any signs of strictures after surgery. Urethral fistulae was diagnosed in 8.3% of cases (1 animal each group). Average graft shrinkage was 55.2% in GI; 44.2% in GII; and 57.2% in GIII (p<0.05). The intensity of chronic inflammation, fibrosis, epithelium regeneration, and neovascularization was similar in all groups (p>0.05). Collagen III/I ratio was higher in GII (GI: 119.6; GII: 257.2 and GIII: 115.0); p<0.01. The four-layer SIS is more advantageous than the one-layer SIS and buccal mucosa for urethral substitution in rabbits.

Disruption of the intestinal microbiota is considered an etiological factor in pediatric functional constipation. Scientifically based selection of potential beneficial probiotic strains in functional constipation therapy is not feasible due to insufficient knowledge of microbiota composition in affected subjects. The aim of this study was to describe microbial composition and diversity in children with functional constipation, compared to healthy controls. Fecal samples from 76 children diagnosed with functional constipation according to the Rome III criteria (median age 8.0 years; range 4.2-17.8) were analyzed by IS-pro, a PCR-based microbiota profiling method. Outcome was compared with intestinal microbiota profiles of 61 healthy children (median 8.6 years; range 4.1-17.9). Microbiota dissimilarity was depicted by principal coordinate analysis (PCoA), diversity was calculated by Shannon diversity index. To determine the most discriminative species, cross validated logistic ridge regression was performed. Applying total microbiota profiles (all phyla together) or per phylum analysis, no disease-specific separation was observed by PCoA and by calculation of diversity indices. By ridge regression, however, functional constipation and controls could be discriminated with 82% accuracy. Most discriminative species were Bacteroides fragilis, Bacteroides ovatus, Bifidobacterium longum, Parabacteroides species (increased in functional constipation) and Alistipes finegoldii (decreased in functional constipation). None of the commonly used unsupervised statistical methods allowed for microbiota-based discrimination of children with functional constipation and controls. By ridge regression, however, both groups could be discriminated with 82% accuracy. Optimization of microbiota-based interventions in constipated children warrants further characterization of microbial signatures linked to clinical subgroups of functional constipation.

In the last eighteen years, from 1972 to 1989, around 150 cases of Wilson's disease have been diagnosed in Costa Rica (6/100.000 inhabitants). In the San Juan de Dios Hospital, 120 cases have been studied during this period, seven of whom died with a picture of acute hepatic insufficiency, hemolytic anemia, encephalopathy, intestinal bleeding and renal insufficiency. In four of the cases, postmortem histopathologic studies were done with high resolution microscopy, which revealed extensive submassive necrosis of the liver, with severe cholestatic, lytic and acidophilic necrosis with nodular, irregular regeneration and specially microvacuolar steatosis, different from that observed in other forms of fulminant hepatitis. With the clinical, laboratory and histopathologic findings, we concluded that fulminant Wilson's disease is a well-defined pathological clinical entity of fatal evolution with no response to therapy, including early treatment with penicillamine and steroids.

Pencil Beam Scanning Proton Therapy for Rhabdomyosarcoma of the Biliary Tract.

Pater, Luke; Turpin, Brian; Mascia, Anthony

2017-10-05

Rhabdomyosarcoma (RMS) is the most common soft tissue sarcoma of childhood with 250-350 cases diagnosed annually in the United States. Biliary tract rhabdomyosarcoma is rare, representing <1% of the RMS cases. Due to its location, resection is clinically challenging, and functional complications exist and persist from biliary obstruction. The anatomical location of this tumor presents both opportunities and challenges for pencil beam scanning proton therapy. Proton therapy offers a dosimetric and clinical advantage by sparing the healthy liver, stomach, contra-lateral kidney and bowel. Motion management and anatomical variations, such as intestinal filling or weight loss, requiring routine dosimetric evaluation and possible adaptive treatment planning, present challenges for the use of proton therapy. By taking advantage of the superior dose distribution of proton radiation, assessing the impact of tumor and anatomy motion, and performing regular dose evaluations, biliary tract RMS is an ideal diagnosis for pencil beam scanning proton therapy.

We report our experience of 15 cases of gastroschisis which occurred between 1981 and 1993. All but one were diagnosed antenatally by ultrasound between 16 and 32 weeks of pregnancy. We made a termination of the pregnancy in 3 cases, for multiple malformations in 2 cases and one case of very early premature rupture of the membranes (PROM). When checked (11 cases), the karyotype was normal. We made a cesarean section in 11 cases: the indication was a complication for 6 (fetal distress, PROM, polyhydramnios, large dilatation of the gut). We noted growth retardation in 7 newborns and prematurity in 5/12 (mean gestational age of 36.8 weeks). The preoperative study of the gut noted 5 cases with intestinal damage and one case of complete necrosis of the gut. The global prognosis is not as good as usual, with a perinatal mortality of 41.6% (5/12). We discuss this latter point and examine the literature.

AIM: To evaluate the clinical outcome of enteroscopy, using the double-balloon method, focusing on the involvement of neoplasms in strictures of the small intestine. METHODS: Enteroscopy, using the double-balloon method, was performed between December 1999 and December 2002 at Jichi Medical School Hospital, Japan and strictures of the small intestine were found in 17 out of 62 patients. These 17 consecutive patients were subjected to analysis. RESULTS: The double-balloon enteroscopy contributed to the diagnosis of small intestinal neoplasms found in 3 out of 17 patients by direct observation of the strictures as well as biopsy sampling. Surgical procedures were chosen for these three patients, while balloon dilation was chosen for the strictures in four patients diagnosed with inflammation without involvement of neoplasm. CONCLUSION: Double-balloon enteroscopy is a useful method for the diagnosis and treatment of strictures in the small bowel. PMID:15742422

Breast cancer is a common malignancy in women and frequently metastasizes to various organs such as liver, lung, brain, bone and so on. But metastasis to gastrointestinal tract is rare. We describe a 73-year-old woman with small intestinal metastasis of breast cancer. She was diagnosed as right breast cancer in stage I, received modified radical mastectomy 6 years ago and had been followed up without any evidence of residual disease. During investigation for lower abdominal pain and weight loss of 9 kg, we found a small bowel mass. The histology of the tissue taken from small bowel mass was adenocarcinoma, poorly differentiated. The immunohistochemical stain of this specimen showed 75% positivity of estrogen receptor and 90% positivity of progesterone receptor. This is a case of small bowel metastasis from breast cancer and we report this case with a review of literatures.

Small bowel volvulus, which is torsion of the small bowel and its mesentery, is a medical emergency, and is categorized as primary or secondary type. Primary type often occurs without any apparent intrinsic anatomical anomalies, while the secondary type is common clinically and could be caused by numerous factors including postoperative adhesions, intestinal diverticulum, and/or tumors. Here, we report a rare case of a 60-year-old man diagnosed with small bowel volvulus using multidetector computed tomography (MDCT) angiography. Further discovery by laparotomy showed one jejunal diverticulum, longer corresponding mesentery with a narrower insertion, and a lack of mesenteric fat. This case report includes several etiological factors of small bowel volvulus, and we discuss the possible cause of small bowel volvulus in this patient. We also highlight the importance of MDCT angiography in the diagnosis of volvulus and share our experience in treating this disease. PMID:26420976

Lymphoproliferative disorder (LPD) is a potentially severe adverse effect of methotrexate (MTX) administration in patients with rheumatoid arthritis (RA). We report a case of MTX-associated LPD (MTX-LPD) in a patient with RA who developed severe pulmonary failure complicated by perforation of the terminal ileum. A 61-year-old woman with RA receiving MTX complained of dyspnea and abdominal pain. She was diagnosed with intestinal perforation and peritonitis, and underwent immediate abdominal surgery. Pathological examinations of the specimen obtained from the resected ileum and a bone marrow aspirate revealed diffuse large B-cell lymphoma. Steroid therapy failed to improve her respiratory failure, but her condition improved after abdominal surgery and suspension of MTX. MTX-LPD can result in multiple life-threatening conditions; however, the symptoms are highly variable. RA patients receiving MTX should thus be monitored carefully, and MTX administration should be stopped immediately on suspicion of MTX-LPD.

Biological barriers are essential for the maintenance of homeostasis in health and disease. Breakdown of the intestinal barrier is an essential aspect of the pathophysiology of gastrointestinal inflammatory diseases, such as inflammatory bowel disease. A wealth of recent studies has shown that the intestinal microbiome, part of the brain-gut axis, could play a role in the pathophysiology of multiple sclerosis. However, an essential component of this axis, the intestinal barrier, has received much less attention. In this review, we describe the intestinal barrier as the physical and functional zone of interaction between the luminal microbiome and the host. Besides its essential role in the regulation of homeostatic processes, the intestinal barrier contains the gut mucosal immune system, a guardian of the integrity of the intestinal tract and the whole organism. Gastrointestinal disorders with intestinal barrier breakdown show evidence of CNS demyelination, and content of the intestinal microbiome entering into the circulation can impact the functions of CNS microglia. We highlight currently available studies suggesting that there is intestinal barrier dysfunction in multiple sclerosis. Finally, we address the mechanisms by which commonly used disease-modifying drugs in multiple sclerosis could alter the intestinal barrier and the microbiome, and we discuss the potential of barrier-stabilizing strategies, including probiotics and stabilization of tight junctions, as novel therapeutic avenues in multiple sclerosis.

The purpose of this study was to evaluate the intestinal metabolism and absorption in a mini-Ussing chamber equipped with animal intestinal tissues, based on the transport index (TI). TI value was defined as the sum of drug amounts transported to the basal-side component (X corr ) and drug amounts accumulated in the tissue (T corr ), which are normalized by AUC of a drug in the apical compartment, as an index for drug absorption. Midazolam was used as a test compound for the evaluation of intestinal metabolism and absorption. The metabolite formulation of midazolam was observed in both rats and dogs. Ketoconazole inhibited the intestinal metabolism of midazolam in rats and improved its intestinal absorption to a statistically significant extent. Therefore, the mini-Ussing chamber, equipped with animal intestinal tissues, showed potential to use the evaluation of the intestinal metabolism and absorption, including the assessment of species differences.

A one-year-old male Golden Retriever presented with acute onset of vomiting and hemorrhagic diarrhea since 2 days. The dog was depressed, showing abdominal pain, 12% dehydration, tachycardia, and a bounding pulse. Diagnostic imaging showed severe dilatation and fluid retention of the entire gastrointestinal tract with decreased motility. A foreign body was found in the gastroduodenal region, but there was no obstruction or plication. The dog was tentatively diagnosed with acute hemorrhagic diarrhea syndrome and rapidly recovered after supportive treatment. However, on the morning of day 4, anorexia and vomiting recurred, and diagnostic imaging revealed intestinal plication with free peritoneal fluid, not found on the previous image. An emergency laparotomy revealed the foreign body to be two used feminine hygiene products. These contaminated products were suspected to induce acute hemorrhagic diarrhea syndrome, and led to subsequent complication in this large dog. PMID:29459505

Celiac disease: implications for patient management.

2011-01-01

Celiac disease is an autoimmune disorder that is known specifically for causing inflammation of the mucosa in the small intestine. Through multiple diagnostic and screening tools such as small intestinal biopsy sample, serological testing, and human leukocyte antigen testing, healthcare providers can diagnose this disease that contains components related to genetic predisposition and intake of gluten proteins found in wheat, barley, and rye. There are some who believe that having an autoimmune disease may predispose one to acquiring another disease. With patients experiencing mostly diarrhea, abdominal pain, and weight loss, the implementation of a gluten-free diet is the treatment that healthcare providers recommend. Through monitoring gluten intake and providing nutritional supplementation, those diagnosed with celiac disease can lead a relatively normal life without complications. With celiac disease affecting all age ranges in the population, and with a documented higher frequency, there is a growing awareness in society that can be easily seen in grocery stores, restaurants, and food manufacturers.

Celiac disease is the most common chronic intestinal disease. Nowadays it´s known that this is a multisistemic pathology of immune mechanism, triggered by gluten, which occurs in genetically susceptible individuals. It affects approximately 1% of the world population, which is a very high prevalence, affects all age groups and has symptoms both digestive and extra-digestive. Since it is a disease that requires maintaining a gluten-free diet and medical monitoring for life, it is important to know it and establish its diagnosis properly. Along with celiac disease a number of new diseases related to gluten are diagnosed increasingly, including the non celiac gluten sensitivity or wheat allergy. The suffering of celiac disease, or other related diseases, by conditioning diet changes of the affected individual, it may be associated with nutritional imbalances that need to monitor and try to solve. Therefore patients with this problem need special nutritional advice.

Indications and Use of the Gluten Contamination Elimination Diet for Patients with Non-Responsive Celiac Disease

PubMed Central

Leonard, Maureen M.; Cureton, Pamela; Fasano, Alessio

2017-01-01

For the majority of patients diagnosed with celiac disease, once a gluten-free diet is initiated, symptoms improve within weeks and may completely resolve in months. However, up to 30% of patients may show signs, symptoms or persistent small intestinal damage after one year on a gluten-free diet. These patients require evaluation for other common GI etiologies and assessment of their celiac disease status in order to make a diagnosis and suggest treatment. Here, we propose an approach to evaluating patients with celiac disease with persistent symptoms, persistently elevated serology, and or persistent villous atrophy despite a gluten-free diet. We detail how to diagnose and distinguish between non-responsive and refractory celiac disease. Finally, we introduce the indications for use of the gluten contamination elimination diet and provide information for practitioners to implement the diet when necessary in their practice.

We report the case of a 19-year-old military trainee that presented to the emergency department with a 3-week history of diffuse abdominal pain, 1 to 2 hours postprandially. The timing, onset, quality, and location of her pain was concerning for intestinal angina. Her serum chemistry, hematology, and liver function tests were normal. The radiologist's interpretation of the computed tomography angiogram of the abdomen was an abnormally narrow takeoff angle of the superior mesenteric artery (SMA) from the aorta near the third portion of the duodenum. She was diagnosed with SMA syndrome and received additional evaluation and treatment by her gastroenterologist and surgeon. SMA syndrome is rare and can cause bowel obstruction, perforation, gastric wall pneumatosis, and portal venous gas formation. Computed tomography angiography can be used to promptly diagnose this syndrome in the emergency department. Reprint & Copyright © 2013 Association of Military Surgeons of the U.S.

Objective: Small intestinal biopsy remains the gold standard in diagnosing celiac disease (CD); however, the wide spectrum of histopathological states and differential diagnosis of CD is still a diagnostic problem for pathologists. Recently, Ensari reviewed the literature and proposed an update of the histopathological diagnosis and classification for CD. Materials and Methods: In this study, the histopathological materials of 54 children in whom CD was diagnosed at our hospital were reviewed to compare the previous Marsh and Modified Marsh-Oberhuber classifications with this new proposal. Results: In this study, we show that the Ensari classification is as accurate as the Marsh and Modified Marsh classifications in describing the consecutive states of mucosal damage seen in CD. Conclusions: Ensari’s classification is simple, practical and facilitative in diagnosing and subtyping of mucosal pathology of CD. PMID:25207015

For the majority of patients diagnosed with celiac disease, once a gluten-free diet is initiated, symptoms improve within weeks and may completely resolve in months. However, up to 30% of patients may show signs, symptoms or persistent small intestinal damage after one year on a gluten-free diet. These patients require evaluation for other common GI etiologies and assessment of their celiac disease status in order to make a diagnosis and suggest treatment. Here, we propose an approach to evaluating patients with celiac disease with persistent symptoms, persistently elevated serology, and or persistent villous atrophy despite a gluten-free diet. We detail how to diagnose and distinguish between non-responsive and refractory celiac disease. Finally, we introduce the indications for use of the gluten contamination elimination diet and provide information for practitioners to implement the diet when necessary in their practice.

Lactose intolerance and other disaccharidase deficiency.

Intolerance to foods which contain lactose can cause a range of intestinal and systemic symptoms. These symptoms are caused by Lactase deficiency which is encoded by a single gene (LCT) of ≈ 50 kb located on chromosome 2q21. In some food items, lactose has been missed because of "hidden" lactose due to inadequately labeled, confusing diagnosis of lactose intolerance based on dietary restriction of dairy foods. Two polymorphisms, C/T13910 and G/A22018, linked to hypolactasia, correlate with breath hydrogen and symptoms after lactose. The key in the management of lactose intolerance is the dietary removal of lactose. Patients diagnosed as lactose intolerant must be advised of "risk" foods, inadequately labeled, including processed meats, bread, cake mixes, soft drinks, and lagers. This review highlights the types, symptoms and management of lactose intolerance and also highlights differences from milk allergy which closely mimics the symptoms of lactose intolerance.

Small bowel volvulus, which is torsion of the small bowel and its mesentery, is a medical emergency, and is categorized as primary or secondary type. Primary type often occurs without any apparent intrinsic anatomical anomalies, while the secondary type is common clinically and could be caused by numerous factors including postoperative adhesions, intestinal diverticulum, and/or tumors. Here, we report a rare case of a 60-year-old man diagnosed with small bowel volvulus using multidetector computed tomography (MDCT) angiography. Further discovery by laparotomy showed one jejunal diverticulum, longer corresponding mesentery with a narrower insertion, and a lack of mesenteric fat. This case report includes several etiological factors of small bowel volvulus, and we discuss the possible cause of small bowel volvulus in this patient. We also highlight the importance of MDCT angiography in the diagnosis of volvulus and share our experience in treating this disease.

An 11-year-old, female neutered Labrador retriever was presented with a micro-invasive differentiated papillar adenocarcinoma at the colorectal junction. A colorectal end-to-end anastomosis stapler device was used to perform resection and anastomosis using a transanal technique. A rectovaginal fistula was diagnosed two days later. An exploratory laparotomy was conducted and the fistula was identified and closed. Early dehiscence of the colon was also suspected and another colorectal anastomosis was performed using a manual technique. Comparison to a conventional manual technique of intestinal surgery showed that the use of an automatic staple device was quicker and easier. To the authors' knowledge, this is the first report of a rectovaginal fistula occurring after end-to-end anastomosis stapler colorectal resection-anastomosis in the dog. To minimise the risk of this potential complication associated with the limited surgical visibility, adequate tissue retraction and inspection of the anastomosis site are essential.

Intestinal barrier breakdown after severe burn can lead to intestinal inflammation, which may act as the source of the systemic inflammatory response. In vitro intestinal cell studies have shown that mitogen-activated protein kinase (MAPK) signaling is an important modulator of intestinal inflammation. We have previously observed that pentoxifylline (PTX) attenuates burn-induced intestinal permeability and tight junction breakdown. We hypothesized that PTX would limit intestinal barrier breakdown and attenuate inflammatory signaling via the MAPK pathway. Male balb/c mice underwent 30% total body surface area full-thickness steam burn. Immediately after burn, animals received an intraperitoneal injection of PTX (12.5 mg/kg) in normal saline or normal saline alone. In vivo intestinal permeability to 4 kDa fluorescein isothiocyanate-dextran was measured. Intestinal extracts were obtained to measure interleukin-6 by enzyme-linked immunosorbent assay, and phosphorylated p38 MAPK, p38 MAPK, phosphorylated extracellular signal-related kinase (1/2) (ERK (1/2)), and ERK (1/2) by immunoblotting. Acute lung injury was assessed by histology at 24 hours after burn. Administration of PTX immediately after injury attenuated burn-induced intestinal permeability. PTX also decreased the burn-induced phosphorylation of p38 MAPK and decreased phosphorylation of ERK (1/2) at 2 hours and 24 hours after injury. Animals given PTX had decreased intestinal interleukin-6 levels. A single dose of PTX also decreased histologic lung injury at 24 hours after burn. PTX attenuates burn-induced intestinal permeability and subsequent intestinal inflammation. Use of PTX after burn was also associated with decreased acute lung injury. Because of its compelling anti-inflammatory effects, PTX may be an ideal candidate for use as an immunomodulatory adjunct to resuscitation fluid.

Acute intestinal edema adversely affects intestinal transit, permeability, and contractility. Current resuscitation modalities, while effective, are associated with development of acute intestinal edema. Knowledge of levels of tissue edema would allow clinicians to monitor intestinal tissue water and may help prevent the detrimental effects of edema. However, there is no simple method to measure intestinal tissue water without biopsy. We sought to develop a tissue impedance analyzer to measure tissue edema, without the need for invasive biopsy. Oscillating voltage input was applied to the analyzer circuit and an oscilloscope measured the voltage output across any load. Rats were randomized to three groups: sham, mild edema (80 mL/kg of NS resuscitation), and severe edema (80 mL/kg of NS resuscitation with intestinal venous hypertension). Intestinal edema was measured by wet-to-dry tissue weight ratio. Bowel impedance was measured and converted to capacitance using a standard curve. Acute intestinal edema causes a significant increase in bowel capacitance. This capacitance can be used to predict tissue water concentration. Using an impedance analyzer circuit, it is possible to measure intestinal edema reliably and quickly. This may prove to be a useful tool in the resuscitation of critically ill patients.

Eosinophils play proinflammatory roles in helminth infections and allergic diseases. Under steady-state conditions, eosinophils are abundantly found in the small intestinal lamina propria, but their physiological function is largely unexplored. In this study, we found that small intestinal eosinophils down-regulate Th17 cells. Th17 cells in the small intestine were markedly increased in the ΔdblGATA-1 mice lacking eosinophils, and an inverse correlation was observed between the number of eosinophils and that of Th17 cells in the small intestine of wild-type mice. In addition, small intestinal eosinophils suppressed the in vitro differentiation of Th17 cells, as well as IL-17 production by small intestinal CD4(+)T cells. Unlike other small intestinal immune cells or circulating eosinophils, we found that small intestinal eosinophils have a unique ability to constitutively secrete high levels of IL-1 receptor antagonist (IL-1Ra), a natural inhibitor of IL-1β. Moreover, small intestinal eosinophils isolated from IL-1Ra-deficient mice failed to suppress Th17 cells. Collectively, our results demonstrate that small intestinal eosinophils play a pivotal role in the maintenance of intestinal homeostasis by regulating Th17 cells via production of IL-1Ra. © 2016 Sugawara et al.

To compare the clinicopathological features of patients with non-schistosomal rectosigmoid cancer and schistosomal rectosigmoid cancer. All the patients with rectosigmoid carcinoma who underwent laparoscopic radical surgical resection in the Shanghai Minimally Invasive Surgical Center at Ruijin Hospital affiliated to Shanghai Jiao-Tong University between October 2009 and October 2013 were included in this study. Twenty-six cases of colonic schistosomiasis diagnosed through colonoscopy and pathological examinations were collected. Symptoms, endoscopic findings and clinicopathological characteristics were evaluated retrospectively. There were no significant differences between patients with and without schistosomiasis in gender, age, CEA, CA19-9, preoperative biopsy findings or postoperative pathology. Patients with rectosigmoid schistosomiasis had a significantly higher CA-125 level and a larger proportion of these patients were at an early tumor stage (P = 0.003). Various morphological characteristics of schistosomiasis combined with rectosigmoid cancer could be found by colonoscopic examination: 46% were fungating mass polyps, 23% were congestive and ulcerative polyps, 23% were cauliflower-like masses, 8% were annular masses. Only 27% of the patients were diagnosed with rectal carcinoma preoperatively after the biopsy. Computed tomography (CT) scans showed thickened intestinal walls combined with linear and tram-track calcifications in 26 patients. Rectosigmoid carcinoma combined with schistosomiasis is associated with higher CA-125 values and early tumor stages. CA-125 and CT scans have a reasonable sensitivity for the accurate diagnosis.

Regulatory immune cells in regulation of intestinal inflammatory response to microbiota

2015-01-01

The intestinal lumen harbors nearly 100 trillion commensal bacteria that exert crucial function for health. An elaborate balance between immune responses and tolerance to intestinal microbiota is required to maintain intestinal homeostasis. This process depends on diverse regulatory mechanisms, including both innate and adaptive immunity. Dysregulation of the homeostasis between intestinal immune systems and microbiota has been shown to be associated with the development of inflammatory bowel diseases (IBD) in genetically susceptible populations. In this review, we discuss the recent progress reported in studies of distinct types of regulatory immune cells in the gut, including intestinal intraepithelial lymphocytes, Foxp3+ regulatory T cells, regulatory B cells, alternatively activated macrophages, dendritic cells, and innate lymphoid cells, and how dysfunction of this immune regulatory system contributes to intestinal diseases such as IBD. Moreover, we discuss the manipulation of these regulatory immune cells as a potential therapeutic method for management of intestinal inflammatory disorders. PMID:26080708

Gut-derived bacterial lipopolysaccharides (LPS) play an essential role in inducing intestinal and systemic inflammatory responses and have been implicated as a pathogenic factor of necrotizing enterocolitis (NEC) and inflammatory bowel disease (IBD). The defective intestinal tight junction (TJ) barrier has been shown to be an important factor contributing to the development of intestinal inflammation. LPS, at physiological concentrations, cause an increase in intestinal tight junction permeability (TJP) via a TLR-4 dependent process; however the intracellular mechanisms that mediate LPS regulation of intestinal TJP remain unclear. The aim of this study was to investigate the adaptor proteins and the signaling interactions that mediate LPS modulation of intestinal TJ barrier using an in-vitro and in-vivo model system. LPS caused a TLR-4 dependent activation of membrane-associated adaptor protein FAK in Caco-2 monolayers. LPS caused an activation of both MyD88-dependent and –independent pathways. SiRNA silencing of MyD88 prevented LPS-induced increase in TJP. LPS caused a MyD88-dependent activation of IRAK4. TLR-4, FAK and MyD88 were co-localized. SiRNA silencing of TLR-4 inhibited TLR-4 associated FAK activation; and FAK knockdown prevented MyD88 activation. In-vivo studies also confirmed that LPS-induced increase in mouse intestinal permeability was associated with FAK and MyD88 activation; knockdown of intestinal epithelial FAK prevented LPS-induced increase in intestinal permeability. Additionally, high dose LPS-induced intestinal inflammation was also dependent on TLR-4/FAK/MyD88 signal-transduction axis. Our data show for the first time that LPS-induced increase in intestinal TJP and intestinal inflammation was regulated by TLR-4 dependent activation of FAK-MyD88-IRAK4 signaling pathway.

DA-6034 has anti-inflammatory activities and exhibits cytoprotective effects in acute gastric injury models. However, explanations for the protective effects of DA-6034 on intestinal permeability are limited. This study sought to investigate the effect of DA-6034 on intestinal permeability in an indomethacin-induced small intestinal injury model and its protective effect against small intestinal injury. Rats in the treatment group received DA-6034 from days 0 to 2 and indomethacin from days 1 to 2. Rats in the control group received indomethacin from days 1 to 2. On the fourth day, the small intestines were examined to compare the severity of inflammation. Intestinal permeability was evaluated by using fluorescein isothiocyanate-labeled dextran. Western blotting was performed to confirm the association between DA-6034 and the extracellular signal-regulated kinase (ERK) pathway. The inflammation scores in the treatment group were lower than those in the control group, but the difference was statistically insignificant. Hemorrhagic lesions in the treatment group were broader than those in the control group, but the difference was statistically insignificant. Intestinal permeability was lower in the treatment group than in the control group. DA-6034 enhanced extracellular signal-regulated kinase expression, and intestinal permeability was negatively correlated with ERK expression. DA-6034 may decrease intestinal permeability in an indomethacin-induced intestinal injury model via the ERK pathway.

Management of short bowel syndrome (SBS) aims to achieve intestinal autonomy to prevent fluid, electrolyte, and nutrient deficiencies and maintain adequate development. Remnant intestinal adaptation is required to obtain autonomy. In the newborn pig, colostrum has been shown to support intestinal development and hence adaptive processes. The efficacy of bovine colostrum to improve intestinal function in children with SBS was evaluated by metabolic balance studies. Nine children with SBS were included in a randomized, double-blind, crossover study. Twenty percent of enteral fluid intake was replaced with bovine colostrum or a mixed milk diet for 4 weeks, separated by a 4-week washout period. Intestinal absorption of energy and wet weight was used to assess intestinal function and the efficacy of colostrum. Colostrum did not improve energy or wet weight absorption compared with the mixed milk diet (P = 1.00 and P = .93, respectively). Growth as measured by weight and knemometry did not differ between diets (P = .93 and P = .28). In these patients, <150% enteral energy absorption of basal metabolic rate and 50% enteral fluid absorption of basal fluid requirement suggested intestinal failure and a need for parenteral nutrition (PN). Inclusion of bovine colostrum to the diet did not improve intestinal function. Metabolic nutrient and wet weight balance studies successfully assessed intestinal function, and this method may distinguish between intestinal insufficiency (non-PN-dependent) and intestinal failure (PN-dependent) patients.

Clostridium perfringens Sialidases: Potential Contributors to Intestinal Pathogenesis and Therapeutic Targets.

PubMed

Li, Jihong; Uzal, Francisco A; McClane, Bruce A

2016-11-19

Clostridium perfringens is a major cause of histotoxic and intestinal infections of humans and other animals. This Gram-positive anaerobic bacterium can produce up to three sialidases named NanH, NanI, and NanJ. The role of sialidases in histotoxic infections, such as gas gangrene (clostridial myonecrosis), remains equivocal. However, recent in vitro studies suggest that NanI may contribute to intestinal virulence by upregulating production of some toxins associated with intestinal infection, increasing the binding and activity of some of those toxins, and enhancing adherence of C. perfringens to intestinal cells. Possible contributions of NanI to intestinal colonization are further supported by observations that the C. perfringens strains causing acute food poisoning in humans often lack the nanI gene, while other C. perfringens strains causing chronic intestinal infections in humans usually carry a nanI gene. Certain sialidase inhibitors have been shown to block NanI activity and reduce C. perfringens adherence to cultured enterocyte-like cells, opening the possibility that sialidase inhibitors could be useful therapeutics against C. perfringens intestinal infections. These initial in vitro observations should be tested for their in vivo significance using animal models of intestinal infections.

The α subunit of the heterotrimeric G stimulatory protein (Gsa), encoded by the guanine nucleotide binding protein, α-stimulating gene (Gnas, in mice), is expressed ubiquitously and mediates receptor-stimulated production of cyclic adenosine monophosphate and activation of the protein kinase A signaling pathway. We investigated the roles of Gsa in vivo in smooth muscle cells of mice. We performed studies of mice with Cre recombinase-mediated disruption of Gnas in smooth muscle cells (Gsa SMKO and SM22-CreER T2 , induced in adult mice by tamoxifen). Intestinal tissues were collected for histologic, biochemical, molecular, cell biology, and physiology analyses. Intestinal function was assessed in mice using the whole-gut transit time test. We compared gene expression patterns of intestinal smooth muscle from mice with vs without disruption of Gnas. Biopsy specimens from ileum of patients with chronic intestinal pseudo-obstruction and age-matched control biopsies were analyzed by immunohistochemistry. Disruption of Gnas in smooth muscle of mice reduced intestinal motility and led to death within 4 weeks. Tamoxifen-induced disruption of Gnas in adult mice impaired contraction of intestinal smooth muscle and peristalsis. More than 80% of these died within 3 months of tamoxifen exposure, with features of intestinal pseudo-obstruction characterized by chronic intestinal dilation and dysmotility. Gsa deficiency reduced intestinal levels of cyclic adenosine monophosphate and transcriptional activity of the cyclic adenosine monophosphate response element binding protein 1 (CREB1); this resulted in decreased expression of the forkhead box F1 gene (Foxf1) and protein, and contractile proteins, such as myosin heavy chain 11; actin, α2, smooth muscle, aorta; calponin 1; and myosin light chain kinase. We found decreased levels of Gsa, FOXF1, CREB1, and phosphorylated CREB1 proteins in intestinal muscle layers of patients with chronic intestinal pseudo-obstruction, compared with tissues from controls. Gsa is required for intestinal smooth muscle contraction in mice, and its levels are reduced in ileum biopsies of patients with chronic intestinal pseudo-obstruction. Mice with disruption of Gnas might be used to study human chronic intestinal pseudo-obstruction. Copyright © 2017 AGA Institute. Published by Elsevier Inc. All rights reserved.

A role for IL-22 in the relationship between intestinal helminths, gut microbiota and mucosal immunity

PubMed Central

Leung, Jacqueline M.; Loke, P’ng

2014-01-01

The intestinal tract is home to nematodes as well as commensal bacteria (microbiota), which have coevolved with the mammalian host. The mucosal immune system must balance between an appropriate response to dangerous pathogens and an inappropriate response to commensal microbiota that may breach the epithelial barrier, in order to maintain intestinal homeostasis. IL-22 has been shown to play a critical role in maintaining barrier homeostasis against intestinal pathogens and commensal bacteria. Here we review the advances in our understanding of the role of IL-22 in helminth infections, as well as in response to commensal and pathogenic bacteria of the intestinal tract. We then consider the relationship between intestinal helminths and gut microbiota and hypothesize that this relationship may explain how helminths may improve symptoms of inflammatory bowel diseases. We propose that by inducing an immune response that includes IL-22, intestinal helminths may enhance the mucosal barrier function of the intestinal epithelium. This may restore the mucosal microbiota populations from dysbiosis associated with colitis and improve intestinal homeostasis. PMID:23178750

Intestinal inflammation plays a critical role in the pathogenesis of intestinal failure (IF). The macrophages are essential to maintain the intestinal homeostasis. However, the underlying mechanisms of intestinal macrophages activation remain poorly understood. Since microRNAs (miRNAs) have pivotal roles in regulation of immune responses, here we aimed to investigate the role of miR-124 in the activation of intestinal macrophages. In this study, we showed that the intestinal macrophages increased in pediatric IF patients and resulted in the induction of interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α). The miRNA fluorescence in situ hybridization analysis showed that the expression of miR-124 significantly reduced in intestinal macrophages in IF patients. Overexpression of miR-124 was sufficient to inhibit intestinal macrophages activation by attenuating production of IL-6 and TNF-α. Further studies showed that miR-124 could directly target the 3′-untranslated region of both signal transducer and activator of transcription 3 (STAT3) and acetylcholinesterase (AChE) mRNAs, and suppress their protein expressions. The AChE potentially negates the cholinergic anti-inflammatory signal by hydrolyzing the acetylcholine. We here showed that intestinal macrophages increasingly expressed the AChE and STAT3 in IF patients when compared with controls. The inhibitors against to STAT3 and AChE significantly suppressed the lipopolysaccharides-induced IL-6 and TNF-α production in macrophages. Taken together, these findings highlight an important role for miR-124 in the regulation of intestinal macrophages activation, and suggest a potential application of miR-124 in pediatric IF treatment regarding as suppressing intestinal inflammation.

Toll-like receptors 2 and 4 modulate intestinal IL-10 differently in ileum and colon.

Inflammatory bowel diseases are consequence of an intestinal homeostasis breakdown in which innate immune dysregulation is implicated. Toll-like receptor (TLR)2 and TLR4 are immune recognition receptors expressed in the intestinal epithelium, the first physical-physiological barrier for microorganisms, to inform the host of the presence of Gram-positive and Gram-negative organisms. Interleukin (IL)-10 is an essential anti-inflammatory cytokine that contributes to maintenance of intestinal homeostasis. Our main aim was to investigate intestinal IL-10 synthesis and release, and whether TLR2 and TLR4 are determinants of IL-10 expression in the intestinal tract. We used Caco-2 cell line as an enterocyte-like cell model, and also ileum and colon from mice deficient in TLR2, TLR4 or TLR2/4 to test the involvement of TLR signaling. Intestinal epithelial cells are able to synthesize and release IL-10 and their expression is increased after TLR2 or TLR4 activation. IL-10 regulation seems to be tissue specific, with IL-10 expression in the ileum regulated by a compensation between TLR2 and TLR4 expression, whereas in the colon, TLR2 and TLR4 affect IL-10 expression independently. Intestinal epithelial cells could release IL-10 in response to TLR activation, playing an intestinal tissue-dependent and critical intestinal immune role.

Wnt/β-catenin signaling supports intestinal homeostasis by regulating proliferation in the crypt. Multiple Wnts are expressed in Paneth cells as well as other intestinal epithelial and stromal cells. Ex vivo, Wnts secreted by Paneth cells can support intestinal stem cells when Wnt signaling is enhanced with supplemental R-Spondin 1 (RSPO1). However, in vivo, the source of Wnts in the stem cell niche is less clear. Genetic ablation of Porcn, an endoplasmic reticulum resident O-acyltransferase that is essential for the secretion and activity of all vertebrate Wnts, confirmed the role of intestinal epithelial Wnts in ex vivo culture. Unexpectedly, mice lacking epithelial Wnt activity (Porcn(Del)/Villin-Cre mice) had normal intestinal proliferation and differentiation, as well as successful regeneration after radiation injury, indicating that epithelial Wnts are dispensable for these processes. Consistent with a key role for stroma in the crypt niche, intestinal stromal cells endogenously expressing Wnts and Rspo3 support the growth of Porcn(Del) organoids ex vivo without RSPO1 supplementation. Conversely, increasing pharmacologic PORCN inhibition, affecting both stroma and epithelium, reduced Lgr5 intestinal stem cells, inhibited recovery from radiation injury, and at the highest dose fully blocked intestinal proliferation. We conclude that epithelial Wnts are dispensable and that stromal production of Wnts can fully support normal murine intestinal homeostasis.

Food handlers play a major role in the transmission of Salmonella serotype Typhi (S. Typhi), Shigella, and intestinal parasites. This study was conducted to determine the prevalence of S. Typhi, Shigella, and intestinal parasites among food handlers at Bahir Dar University, Ethiopia. A cross-sectional study was conducted in June 2014. Stool samples from 410 food handlers were examined for bacterial pathogens and parasites. Pearson's Chi-square test, Fisher's exact test, and bivariate and multivariate logistic regression analyses were used where appropriate. The prevalence of S. Typhi, Shigella, and intestinal parasites among food handlers was 11 (2.7%), 5 (1.2%), and 53 (12.9%), respectively. Among eight intestinal parasites identified, the two most prevalent intestinal parasites were hookworm 26 (6.3%) and G. lamblia 13 (3.1%). Male food handlers were more likely to be positive than were female food handlers for S. Typhi and intestinal parasites. Furthermore, food handlers who had a history of regular medical checkups were less infected with intestinal parasites. Being male (AOR: 2.1, 95% CI: 1.2, 4.4) and not attending medical checkups (AOR: 2.9, 95% CI: 1.4, 6.1) were independent predictors of intestinal parasitic infection in food handlers. Male food handlers were reluctant to have regular parasitological examinations. There was a high proportion of food handlers with S. Typhi, Shigella, and intestinal parasites in their faces. Special emphasis should be placed on S. Typhicarriers and male food handlers. Education and periodical medical checkups for intestinal parasites and S. Typhi should be considered as intervention measures.

TLR2 is a microbiota recognition receptor that has been described to contribute to intestinal homeostasis and to ameliorate inflammatory intestinal injury. In this context, serotonin (5-HT) has shown to be an essential intestinal physiological neuromodulator that is also involved in intestinal inflammatory diseases. Since the interaction between TLR2 activation and the intestinal serotoninergic system remains non-investigated, our main aim was to analyze the effect of TLR2 on intestinal serotonin transporter (SERT) activity and expression and the intracellular pathways involved. Caco-2/TC7 cells were used to analyze SERT and TLR2 molecular expression and SERT activity by measuring 5-HT uptake. The results showed that apical TLR2 activation inhibits SERT activity in Caco-2/TC7 cells mainly by reducing SERT protein level either in the plasma membrane, after short-term TLR2 activation or in both the plasma membrane and cell lysate, after long-term activation. cAMP/PKA pathway appears to mediate short-term inhibitory effect of TLR2 on SERT; however, p38 MAPK pathway has been shown to be involved in both short- and long-term TLR2 effect. Reciprocally, 5-HT long-term treatment yielded TLR2 down regulation in Caco-2/TC7 cells. Finally, results from in vivo showed an augmented intestinal SERT expression in mice Tlr2-/-, thus confirming our inhibitory effect of TLR2 on intestinal SERT in vitro. The present work infers that TLR2 may act in intestinal pathophysiology, not only by its inherent innate immune role, but also by regulating the intestinal serotoninergic system. PMID:28033388

Background Inflammatory bowel diseases are consequence of an intestinal homeostasis breakdown in which innate immune dysregulation is implicated. Toll-like receptor (TLR)2 and TLR4 are immune recognition receptors expressed in the intestinal epithelium, the first physical-physiological barrier for microorganisms, to inform the host of the presence of Gram-positive and Gram-negative organisms. Interleukin (IL)-10 is an essential anti-inflammatory cytokine that contributes to maintenance of intestinal homeostasis. Aim Our main aim was to investigate intestinal IL-10 synthesis and release, and whether TLR2 and TLR4 are determinants of IL-10 expression in the intestinal tract. Methods We used Caco-2 cell line as an enterocyte-like cell model, and also ileum and colon from mice deficient in TLR2, TLR4 or TLR2/4 to test the involvement of TLR signaling. Results Intestinal epithelial cells are able to synthesize and release IL-10 and their expression is increased after TLR2 or TLR4 activation. IL-10 regulation seems to be tissue specific, with IL-10 expression in the ileum regulated by a compensation between TLR2 and TLR4 expression, whereas in the colon, TLR2 and TLR4 affect IL-10 expression independently. Conclusions Intestinal epithelial cells could release IL-10 in response to TLR activation, playing an intestinal tissue-dependent and critical intestinal immune role. PMID:29774159

The intestinal complement system in inflammatory bowel disease: Shaping intestinal barrier function.

PubMed

Sina, Christian; Kemper, Claudia; Derer, Stefanie

The complement system is part of innate sensor and effector systems such as the Toll-like receptors (TLRs). It recognizes and quickly systemically and/or locally respond to microbial-associated molecular patterns (MAMPs) with a tailored defense reaction. MAMP recognition by intestinal epithelial cells (IECs) and appropriate immune responses are of major importance for the maintenance of intestinal barrier function. Enterocytes highly express various complement components that are suggested to be pivotal for proper IEC function. Appropriate activation of the intestinal complement system seems to play an important role in the resolution of chronic intestinal inflammation, while over-activation and/or dysregulation may worsen intestinal inflammation. Mice deficient for single complement components suffer from enhanced intestinal inflammation mimicking the phenotype of patients with chronic inflammatory bowel disease (IBD) such as Crohn's disease (CD) or ulcerative colitis (UC). However, the mechanisms leading to complement expression in IECs seem to differ markedly between UC and CD patients. Hence, how IECs, intestinal bacteria and epithelial cell expressed complement components interact in the course of IBD still remains to be mostly elucidated to define potential unique patterns contributing to the distinct subtypes of intestinal inflammation observed in CD and UC.

2012-01-01

Background Severe burn injury results in the loss of intestinal barrier function, however, the underlying mechanism remains unclear. Myosin light chain (MLC) phosphorylation mediated by MLC kinase (MLCK) is critical to the pathophysiological regulation of intestinal barrier function. We hypothesized that the MLCK-dependent MLC phosphorylation mediates the regulation of intestinal barrier function following burn injury, and that MLCK inhibition attenuates the burn-induced intestinal barrier disfunction. Methodology/Principal Findings Male balb/c mice were assigned randomly to either sham burn (control) or 30% total body surface area (TBSA) full thickness burn without or with intraperitoneal injection of ML-9 (2 mg/kg), an MLCK inhibitor. In vivo intestinal permeability to fluorescein isothiocyanate (FITC)-dextran was measured. Intestinal mucosa injury was assessed histologically. Tight junction proteins ZO-1, occludin and claudin-1 was analyzed by immunofluorescent assay. Expression of MLCK and phosphorylated MLC in ileal mucosa was assessed by Western blot. Intestinal permeability was increased significantly after burn injury, which was accompanied by mucosa injury, tight junction protein alterations, and increase of both MLCK and MLC phosphorylation. Treatment with ML-9 attenuated the burn-caused increase of intestinal permeability, mucosa injury, tight junction protein alterations, and decreased MLC phosphorylation, but not MLCK expression. Conclusions/Significance The MLCK-dependent MLC phosphorylation mediates intestinal epithelial barrier dysfunction after severe burn injury. It is suggested that MLCK-dependent MLC phosphorylation may be a critical target for the therapeutic treatment of intestinal epithelial barrier disruption after severe burn injury. PMID:22529961

Intestinal intussusception (ISS) commonly causes intestinal obstruction in children. One mechanism that has been proposed to cause ISS is inflammation-induced alteration of intestinal motility. We investigated whether innate inflammatory factors or altered motility is required for induction of ISS by LPS. We compared rates of ISS among BALB/c and C57BL/6 mice, mice lacking lymphocytes or depleted of phagocytes, or mice with defects in the Toll-like receptor 4 (TLR4) signaling pathway following administration of LPS or the Ca2+ analog MnCl2. At 6 or 2 h after administration of LPS or MnCl2, respectively, mice underwent image analysis to assess intestinal contraction rate or laparotomy to identify ISS. LPS-induced ISS (LPS-ISS) was observed in BALB/c mice, but not in C57BL/6 mice or any BALB/c mice with disruptions of TLR4 signaling. LPS-induced serum TNF-α, IL-6, and nitric oxide (NO) and intestinal NO levels were similar in BALB/c and C57BL/6 mice. The rate of LPS-ISS was significantly reduced in phagocyte-depleted, but not lymphocyte-deficient, mice. Intestinal contraction rates were reduced in LPS-ISS-susceptible BALB/c mice, but not in LPS-ISS-resistant C57BL/6 or TLR4 mutant mice, suggesting a role for reduced intestinal contraction rate in LPS-ISS susceptibility. This was tested with MnCl2, a Ca2+ antagonist that reduced intestinal contraction rates and induced ISS, irrespective of mouse strain. Therefore, LPS-ISS is initiated by innate immune signaling that requires TLR4 and phagocytes but may be independent of TNF-α, IL-6, and NO levels. Furthermore, alteration of intestinal motility, specifically, reduced intestinal contraction rate, is a key factor in the development of ISS. PMID:24407593

To investigate the impact of the preinduced intestinal heat shock protein 70 (HSP70) on the visceral hypersensitivity and abnormal intestinal motility in a post-infectious irritable bowel syndrome (PI-IBS) mouse model. Eighty-four female C57BL/6 mice were randomly assigned to four groups: control group (n = 21) and induction + PI-IBS group (n = 21), PI-IBS group (n = 21) and induction group (n = 21). The mice in PI-IBS group were infected in vivo with Trichinella spiralis by oral administration. The visceral hypersensitivity and intestinal motility were evaluated respectively with abdominal withdrawal reflex and colon transportation test. The intestinal HSP70 protein and mRNA level was measured by Western blot and real-time PCR. Meanwhile, the intestinal proinflammatory cytokines IL-10 and TNF-α level was detected by ELISA. Compared with their counterparts in PI-IBS group, the animals in the Induction + PI-IBS group show significantly increased intestinal level of HSP70 and obviously ameliorative clinical figures, including abdominal withdrawal reflex score, intestine transportation time and Bristol scores (P < 0.05). Meanwhile, the intestinal post-inflammatory cytokines remarkably changed, including increased IL-10 level and decreased TNF-α level (P < 0.05). Intestinal HSP70 may play a potential protective role through improving the imbalance between the intestinal post-inflammatory and anti-inflammatory cytokines in PI-IBS.

The underlying mechanisms of how self-renewing cells are controlled in regenerating tissues and cancer remain ambiguous. PCNA-associated factor (PAF) modulates DNA repair via PCNA. Also, PAF hyperactivates Wnt/β-catenin signaling independently of PCNA interaction. We found that PAF is expressed in intestinal stem and progenitor cells (ISCs and IPCs) and markedly upregulated during intestinal regeneration and tumorigenesis. Whereas PAF is dispensable for intestinal homeostasis, upon radiation injury, genetic ablation of PAF impairs intestinal regeneration along with the severe loss of ISCs and Myc expression. Mechanistically, PAF conditionally occupies and transactivates the c-Myc promoter, which induces the expansion of ISCs/IPCs during intestinal regeneration. In mouse models, PAF knockout inhibits Apc inactivation-driven intestinal tumorigenesis with reduced tumor cell stemness and suppressed Wnt/β-catenin signaling activity, supported by transcriptome profiling. Collectively, our results unveil that the PAF-Myc signaling axis is indispensable for intestinal regeneration and tumorigenesis by positively regulating self-renewing cells.

To study the previously discovered clinical entity of adult intestinal duplication and its treatment, and propose an extension to its existing classification. We report the case of an adult male with abdominal pain, constipation and vomiting. This patient underwent surgical separation of adhesions, reduction of torsion and intestinal decompression. Postoperative pathological findings confirmed the rare diagnosis of intestinal duplication. Adult intestinal duplication is quite rare. Its clinical manifestations are nonspecific. From this finding of intestinal duplication originating at the opposite side of the mesenteric margin, a further extension of the existing anatomical classification is proposed.

Six duodenally and ileally cannulated steers were used in 3 sequential studies to measure 1) basal nutrient flows from a soybean hull-based diet, 2) small intestinal digestibility of raw cornstarch continuously infused into the duodenum, and 3) responses of small intestinal starch digestion to duodenal infusion of 200 or 400 g/d casein. Our objective was to evaluate responses in small intestinal starch digestion in cattle over time and to measure responses in small intestinal starch digestion to increasing amounts of MP. On average, cattle consumed 3.7 kg/d DM, 68 g/d dietary N, and 70 g/d dietary starch. Starch flow to the duodenum was small (38 g/d), and N flow was 91 g/d. Small intestinal digestibility of duodenal N was 57%, and small intestinal digestion of duodenal starch flow was extensive (92%). Small intestinal starch digestibility was 34% when 1.5 kg/d raw cornstarch was continuously infused into the duodenum. Subsequently, cattle were placed in 1 of 2 replicated Latin squares that were balanced for carryover effects to determine response to casein infusions and time required for adaptation. Duodenal infusion of casein linearly increased (P ≤ 0.05) small intestinal starch digestibility, and small intestinal starch digestion adapted to infusion of casein in 6 d. Ethanol-soluble starch and unpolymerized glucose flowing to the ileum increased linearly (P ≤ 0.05) with increasing infusion of casein. Plasma cholecystokinin was not affected by casein infusion, but circulating levels of glucose were increased by casein supplementation (P ≤ 0.05). Responses in small intestinal starch digestion in cattle adapted to casein within 6 d, and increases in duodenal supply of casein up to 400 g/d increased small intestinal starch digestion in cattle.

Interactions Between the Intestinal Microbiome and Liver Diseases

The human intestine harbors a diverse community of microbes that promote metabolism and digestion in their symbiotic relationship with the host. Disturbance of its homeostasis can result in disease. We review factors that disrupt intestinal homeostasis and contribute to non-alcoholic fatty liver disease (NAFLD), steatohepatitis (NASH), alcoholic liver disease, and cirrhosis. Liver disease has long been associated with qualitative and quantitative (overgrowth) dysbiotic changes in the intestinal microbiota. Extrinsic factors, such as the Western diet and alcohol, contribute to these changes. Dysbiosis results in intestinal inflammation, a breakdown of the intestinal barrier, and translocation of microbial products in animal models. However, the contribution of the intestinal microbiome to liver disease goes beyond simple translocation of bacterial products that promote hepatic injury and inflammation. Microbial metabolites produced in a dysbiotic intestinal environment and host factors are equally important in the pathogenesis of liver disease. We review how the combination of liver insult and disruptions in intestinal homeostasis contribute to liver disease. PMID:24440671

Research highlights: {yields} Exogenous GIP inhibits intestinal motility through a somatostatin-mediated pathway. {yields} Exogenous GIP inhibits intestinal glucose absorption by reducing intestinal motility. {yields} The GIP-receptor-mediated action in intestine does not involve in GLP-1-mediated pathway. -- Abstract: Gastric inhibitory polypeptide (GIP) is released from the small intestine upon meal ingestion and increases insulin secretion from pancreatic {beta} cells. Although the GIP receptor is known to be expressed in small intestine, the effects of GIP in small intestine are not fully understood. This study was designed to clarify the effect of GIP on intestinal glucose absorption and intestinal motility. Intestinal glucosemore » absorption in vivo was measured by single-pass perfusion method. Incorporation of [{sup 14}C]-glucose into everted jejunal rings in vitro was used to evaluate the effect of GIP on sodium-glucose co-transporter (SGLT). Motility of small intestine was measured by intestinal transit after oral administration of a non-absorbed marker. Intraperitoneal administration of GIP inhibited glucose absorption in wild-type mice in a concentration-dependent manner, showing maximum decrease at the dosage of 50 nmol/kg body weight. In glucagon-like-peptide-1 (GLP-1) receptor-deficient mice, GIP inhibited glucose absorption as in wild-type mice. In vitro examination of [{sup 14}C]-glucose uptake revealed that 100 nM GIP did not change SGLT-dependent glucose uptake in wild-type mice. After intraperitoneal administration of GIP (50 nmol/kg body weight), small intestinal transit was inhibited to 40% in both wild-type and GLP-1 receptor-deficient mice. Furthermore, a somatostatin receptor antagonist, cyclosomatostatin, reduced the inhibitory effect of GIP on both intestinal transit and glucose absorption in wild-type mice. These results demonstrate that exogenous GIP inhibits intestinal glucose absorption by reducing intestinal motility through a somatostatin-mediated pathway rather than through a GLP-1-mediated pathway.« less

Background While our knowledge of the intestinal microbiota during disease is accumulating, basic information of the microbiota in healthy subjects is still scarce. The aim of this study was to characterize the intestinal microbiota of healthy adults and specifically address its temporal stability, core microbiota and relation with intestinal symptoms. We carried out a longitudinal study by following a set of 15 healthy Finnish subjects for seven weeks and regularly assessed their intestinal bacteria and archaea with the Human Intestinal Tract (HIT)Chip, a phylogenetic microarray, in conjunction with qPCR analyses. The health perception and occurrence of intestinal symptoms was recorded by questionnaire at each sampling point. Principal Findings A high overall temporal stability of the microbiota was observed. Five subjects showed transient microbiota destabilization, which correlated not only with the intake of antibiotics but also with overseas travelling and temporary illness, expanding the hitherto known factors affecting the intestinal microbiota. We identified significant correlations between the microbiota and common intestinal symptoms, including abdominal pain and bloating. The most striking finding was the inverse correlation between Bifidobacteria and abdominal pain: subjects who experienced pain had over five-fold less Bifidobacteria compared to those without pain. Finally, a novel computational approach was used to define the common core microbiota, highlighting the role of the analysis depth in finding the phylogenetic core and estimating its size. The in-depth analysis suggested that we share a substantial number of our intestinal phylotypes but as they represent highly variable proportions of the total community, many of them often remain undetected. Conclusions/Significance A global and high-resolution microbiota analysis was carried out to determine the temporal stability, the associations with intestinal symptoms, and the individual and common core microbiota in healthy adults. The findings provide new approaches to define intestinal health and to further characterize the microbial communities inhabiting the human gut. PMID:21829582

Intestinal ischemia-reperfusion (I/R) causes gut dysfunction and promotes multi-organ failure. The liver and kidney can be affected by multi-organ failure after intestinal I/R. Organic anion transporting polypeptides (OATPs) and organic anion transporters (OATs) are recognized in a broad spectrum from endogenous compounds to xenobiotics, including clinically important drugs. Therefore, it is important for understanding the pharmacokinetics to obtain evidence of alterations in OATPs and OATs expression and transport activities. In the present study, we investigated the expression of rat Oatps and Oats after intestinal I/R. We used intestinal ischemia-reperfusion (I/R) model rats. Real-time PCR and Western blotting were used to assess mRNA and protein expression levels. Plasma concentration and biliary excretion of sulfobromophthalein (BSP), which is used as a model compound of organic anion drugs, were measured after intravenous administration in intestinal I/R rats. Although Oat1 and Oat3 mRNA levels were not altered in the kidney, Oatp1a1, Oatp1b2 and Oatp2b1 mRNA levels in the liver were significantly decreased at 1-6 h after intestinal I/R. Moreover, Oatp1a1 and Oatp2b1 protein expression levels were decreased at 1 h after intestinal I/R. Plasma concentration of BSP, which is a typical substrate of Oatps, in intestinal I/R rats reperfused 1 h was increased than that in sham-operated rats. Moreover, the area under the concentration-time curve (AUC₀₋₉₀) in intestinal I/R rats reperfused 1 h was significantly increased than that in sham-operated rats. The total clearance (CL(tot)) and the biliary clearance (CL(bile)) in intestinal I/R rats reperfused 1 h were significantly decreased than those in sham-operated rats. Oatp1a1 and Oatp2b1 expression levels are decreased by intestinal I/R. The decreases in these transporters cause alteration of pharmacokinetics of organic anion compound. The newly found influence of intestinal I/R on the expression and function of Oatps may be a key to perform appropriate drug therapy.

The advent of regional multidisciplinary intestinal rehabilitation programs has been associated with improved survival in pediatric intestinal failure. Yet, the optimal timing of referral for intestinal rehabilitation remains unknown. We hypothesized that the degree of intestinal failure-associated liver disease (IFALD) at initiation of intestinal rehabilitation would be associated with overall outcome. The multicenter, retrospective Pediatric Intestinal Failure Consortium (PIFCon) database was used to identify all subjects with baseline bilirubin data. Conjugated bilirubin (CBili) was used as a marker for IFALD, and we stratified baseline bilirubin values as CBili<2 mg/dL, CBili 2-4 mg/dL, and CBili>4 mg/dL. The association between baseline CBili and mortality was examined using Cox proportional hazards regression. Of 272 subjects in the database, 191 (70%) children had baseline bilirubin data collected. 38% and 28% of patients had CBili >4 mg/dL and CBili <2 mg/dL, respectively, at baseline. All-cause mortality was 23%. On univariate analysis, mortality was associated with CBili 2-4 mg/dL, CBili >4 mg/dL, prematurity, race, and small bowel atresia. On regression analysis controlling for age, prematurity, and diagnosis, the risk of mortality was increased by 3-fold for baseline CBili 2-4 mg/dL (HR 3.25 [1.07-9.92], p=0.04) and 4-fold for baseline CBili >4 mg/dL (HR 4.24 [1.51-11.92], p=0.006). On secondary analysis, CBili >4 mg/dL at baseline was associated with a lower chance of attaining enteral autonomy. In children with intestinal failure treated at intestinal rehabilitation programs, more advanced IFALD at referral is associated with increased mortality and decreased prospect of attaining enteral autonomy. Early referral of children with intestinal failure to intestinal rehabilitation programs should be strongly encouraged. Treatment Study, Level III. Copyright © 2017 Elsevier Inc.

[Gut barrier in the critically ill patient: facts and trends].

PubMed

Velasco, Nicolás

2006-08-01

The disturbances of gut barrier in critically ill patients may influence their outcome and prognosis. Experiments in animals show that fasting and stress collaborate to produce intestinal atrophy and translocation of microorganisms and toxins. This fact is one of the main arguments to promote the use of early enteral feeding in critically ill patients. However, the intestinal barrier behaves differently in humans than in animals. The human enteral cells have a good tolerance to fasting and stress, mucosal atrophy is mild and it is not always associated with changes in intestinal permeability. Moreover, the relationship between intestinal permeability with sepsis and bacterial translocation is controversial. This last phenomenon also happens in normal subjects and may be a mechanism to build immunological memory. One of the most important factors that influence bacterial translocation is the microorganism, that under stress conditions can adhere to the intestinal cell and penetrate the intestinal barrier. Splanchnic ischemia and reperfusion is one of the main pathogenic factors in the failure of intestinal barrier. Finally, the fact that the small bowel is an inflammatory target of extra intestinal injuries, explains several clinical situations. The pathophysiology of the intestinal barrier definitely requires more research.

SUMMARY The intestinal epithelium has a remarkable capacity to regenerate after injury and DNA damage. Here, we show that the integrin effector protein Focal Adhesion Kinase (FAK) is dispensable for normal intestinal homeostasis and DNA damage signaling, but is essential for intestinal regeneration following DNA damage. Given Wnt/c-Myc signaling is activated following intestinal regeneration, we investigated the functional importance of FAK following deletion of the Apc tumor suppressor protein within the intestinal epithelium. Following Apc loss, FAK expression increased in a c-Myc-dependent manner. Codeletion of Apc and Fak strongly reduced proliferation normally induced following Apc loss, and this was associated with reduced levels of phospho-Akt and suppression of intestinal tumorigenesis in Apc heterozygous mice. Thus, FAK is required downstream of Wnt Signaling, for Akt/mTOR activation, intestinal regeneration, and tumorigenesis. Importantly, this work suggests that FAK inhibitors may suppress tumorigenesis in patients at high risk of developing colorectal cancer. PMID:20708588

Intestinal radiation syndrome: sepsis and endotoxin

Rats were whole-body irradiated with 8-MeV cyclotron-produced neutrons and /sup 137/Cs ..gamma.. rays to study the role of enteric bacteria and endotoxin in the intestinal radiation syndrome. Decrease in intestinal weight was used as an index of radiation-induced breakdown of the mucosa. Neutron and ..gamma..-ray doses that were sublethal for intestinal death resulted in a dose-dependent decrease in intestinal weight, reaching minimal values 2 to 3 days after exposure, followed by recovery within 5 days after irradiation. Neutron and photon doses that caused intestinal death resulted in greater mucosal breakdown with little or no evidence of mucosal recovery. The presencemore » of fluid in the intestine and diarrhea, but not bacteremia or endotoxemia, were related to mucosal breakdown and recovery. Neither sepsis nor endotoxin could be detected in liver samples taken at autopsy from animals which died a short time earlier from intestinal injury. These results suggest that overt sepsis and endotoxemia do not play a significant role in the intestinal radiation syndrome.« less

Intestinal absorption of dideoxynucleosides: characterization using a multiloop in situ technique.

1995-01-01

The intestinal absorption of dideoxynucleosides was studied in rabbits, using a closed-loop mesenteric-sampling in situ technique developed in this laboratory, and the kinetic profiles were characterized. Each of the dideoxynucleosides exhibited different dependence on the intestinal regions studied: 3'-azido-2',3'-dideoxythymidine was best absorbed from the ileum, while 2',3'-dideoxyinosine and 2',3'-dideoxycytidine were preferentially absorbed from the jejunum. The results were validated by the mass-balance approach; the percent of drug retained in the intestinal lumen and that degraded at the intestinal pH, by colonic flora, in the intestinal tissue, and in plasma were assessed.

Background & Aims Intestinal inflammation is a hallmark of cystic fibrosis (CF). Administration of probiotics can reduce intestinal inflammation and the incidence of pulmonary exacerbations. We investigated the composition of intestinal microbiota in children with CF and analyzed its relationship with intestinal inflammation. We also investigated the microflora structure before and after Lactobacillus GG (LGG) administration in children with CF with and without antibiotic treatment. Methods The intestinal microbiota were analyzed by denaturing gradient gel electrophoresis (DGGE), real-time polymerase chain reaction (RT-PCR), and fluorescence in situ hybridization (FISH). Intestinal inflammation was assessed by measuring fecal calprotectin (CLP) and rectal nitric oxide (rNO) production in children with CF as compared with healthy controls. We then carried out a small double-blind randomized clinical trial with LGG. Results Twenty-two children with CF children were enrolled in the study (median age, 7 years; range, 2–9 years). Fecal CLP and rNO levels were higher in children with CF than in healthy controls (184±146 µg/g vs. 52±46 µg/g; 18±15 vs. 2.6±1.2 µmol/L NO2 −, respectively; P<0.01). Compared with healthy controls, children with CF had significantly different intestinal microbial core structures. The levels of Eubacterium rectale, Bacteroides uniformis, Bacteroides vulgatus, Bifidobacterium adolescentis, Bifidobacterium catenulatum, and Faecalibacterium prausnitzii were reduced in children with CF. A similar but more extreme pattern was observed in children with CF who were taking antibiotics. LGG administration reduced fecal CLP and partially restored intestinal microbiota. There was a significant correlation between reduced microbial richness and intestinal inflammation. Conclusions CF causes qualitative and quantitative changes in intestinal microbiota, which may represent a novel therapeutic target in the treatment of CF. Administration of probiotics restored gut microbiota, supporting the efficacy of probiotics in reducing intestinal inflammation and pulmonary exacerbations.

The intestinal tract of the fetus matures rapidly in the third trimester of the pregnancy. The premature infant has decreased intestinal motility, limited digestion, absorption and excretion, and poor intestinal barrier defense. These limitations place the infant at high risk for acute intestinal injury, necrotizing enterocolitis. This article reviews the development of the gastrointestinal tract in the fetus, the barriers to feeding the high risk, premature infant, and the most serious intestinal disease, necrotizing enterocolitis.

Clostridium perfringens Sialidases: Potential Contributors to Intestinal Pathogenesis and Therapeutic Targets

PubMed Central

Li, Jihong; Uzal, Francisco A.; McClane, Bruce A.

Clostridium perfringens is a major cause of histotoxic and intestinal infections of humans and other animals. This Gram-positive anaerobic bacterium can produce up to three sialidases named NanH, NanI, and NanJ. The role of sialidases in histotoxic infections, such as gas gangrene (clostridial myonecrosis), remains equivocal. However, recent in vitro studies suggest that NanI may contribute to intestinal virulence by upregulating production of some toxins associated with intestinal infection, increasing the binding and activity of some of those toxins, and enhancing adherence of C. perfringens to intestinal cells. Possible contributions of NanI to intestinal colonization are further supported by observations that the C. perfringens strains causing acute food poisoning in humans often lack the nanI gene, while other C. perfringens strains causing chronic intestinal infections in humans usually carry a nanI gene. Certain sialidase inhibitors have been shown to block NanI activity and reduce C. perfringens adherence to cultured enterocyte-like cells, opening the possibility that sialidase inhibitors could be useful therapeutics against C. perfringens intestinal infections. These initial in vitro observations should be tested for their in vivo significance using animal models of intestinal infections. PMID:27869757

The intestinal tract is home to nematodes as well as commensal bacteria (microbiota), which have coevolved with the mammalian host. The mucosal immune system must balance between an appropriate response to dangerous pathogens and an inappropriate response to commensal microbiota that may breach the epithelial barrier, in order to maintain intestinal homeostasis. IL-22 has been shown to play a critical role in maintaining barrier homeostasis against intestinal pathogens and commensal bacteria. Here we review the advances in our understanding of the role of IL-22 in helminth infections, as well as in response to commensal and pathogenic bacteria of the intestinal tract. We then consider the relationship between intestinal helminths and gut microbiota and hypothesize that this relationship may explain how helminths may improve symptoms of inflammatory bowel diseases. We propose that by inducing an immune response that includes IL-22, intestinal helminths may enhance the mucosal barrier function of the intestinal epithelium. This may restore the mucosal microbiota populations from dysbiosis associated with colitis and improve intestinal homeostasis. Copyright © 2012 Australian Society for Parasitology Inc.

Chronic exposure to high concentrations of hexavalent chromium (Cr(VI)) in drinking water causes intestinal adenomas and carcinomas in mice, but not in rats. Cr(VI) causes damage to intestinal villi and crypt hyperplasia in mice after only one week of exposure. After two years of exposure, intestinal damage and crypt hyperplasia are evident in mice (but not rats), as are intestinal tumors. Although Cr(VI) has genotoxic properties, these findings suggest that intestinal tumors in mice arise as a result of chronic mucosal injury. To better understand the mode of action (MOA) of Cr(VI) in the intestine, a 90-day drinking water study was conducted to collect histological, biochemical, toxicogenomic and pharmacokinetic data in intestinal tissues. Using MOA analyses and human relevance frameworks proposed by national and international regulatory agencies, the weight of evidence supports a cytotoxic MOA with the following key events: (a) absorption of Cr(VI) from the intestinal lumen, (b) toxicity to intestinal villi, (c) crypt regenerative hyperplasia and (d) clonal expansion of mutations within the crypt stem cells, resulting in late onset tumorigenesis. This article summarizes the data supporting each key event in the MOA, as well as data that argue against a mutagenic MOA for Cr(VI)-induced intestinal tumors. PMID:23445218

Severe burns initiate an inflammatory cascade within the gut, which leads to intestinal mucosal injury. Although Na(+)/H(+) exchanger 1 (NHE1) is recognised as a pivotal player in several inflammatory processes, its role in burn-induced intestinal injury is relatively unknown. We hypothesised that NHE1 might be involved in the increased intestinal permeability and barrier breakdown after severe burns. Thus, we here investigate whether the inhibition of NHE1 has a protective effect on burn-induced intestinal injury. Mice were subjected to a 30% total body surface area (TBSA) full-thickness steam burn. Cariporide was used to assess the function of NHE1 in mice with burn-induced intestinal injury by fluorescence spectrophotometry, Western blotting and enzyme linked immunosorbent assay (ELISA). We found that severe burn increased intestinal permeability, associated with the up-regulation of NHE1 and raised inflammatory cytokine levels. Mice treated with the NHE1 inhibitor cariporide had significantly attenuated burn-induced intestinal permeability and a reduced inflammatory response. NHE1 inhibition also reduced nuclear factor-κB (NF-κB) activation and attenuated p38 mitogen-activated protein kinase (MAPK) phosphorylation. Our study suggests that NHE1 plays an important role in burn-induced intestinal permeability through the regulation of the inflammatory response. Inhibition of NHE1 may be adopted as a potential therapeutic strategy for attenuating intestinal barrier breakdown. Copyright © 2013 Elsevier Ltd and ISBI. All rights reserved.

The problem of intestinal parasitic infection in human immunodeficiency virus (HIV)-infected people requires careful consideration in the developing world where poor nutrition is associated with poor hygiene and several coinfecting diseases. Studies have addressed this issue in Cameroon, especially in the low HIV prevalence area. The current study was conducted to determine the prevalence of intestinal parasitosis in people living with HIV (PLHIV) in Adamaoua and to identify associated risk factors. Stool and blood specimens from study participants were screened for intestinal parasites and anti-HIV antibodies, respectively. Of 235 participants, 68 (28.9%) were HIV positive, 38 of them on antiretroviral treatment (ART). The overall prevalence of intestinal parasites was 32.3%. Of 68 PLHIV, 32.3% (22/68) were infected with intestinal parasites, compared with 32.3% (54/167) of the HIV-negative patients. Univariate analysis showed no difference between the prevalence of intestinal parasites among PLHIV and HIV-negative patients ( P = 0.69). ART was not associated with the prevalence of intestinal parasites. Multivariate analysis showed that the quality of water and the personal hygiene were the major risk factors associated to intestinal parasitosis. The level of education was associated with HIV serostatus: the higher the level of education, the lower the risk of being infected with HIV ( P = 0.00). PLHIV and the general population should be screened routinely for intestinal parasites and treated if infected.

Fabricated induced illness (FII) is recognised amongst children presenting with suspected Chronic Intestinal Pseudo-Obstruction (CIPO) (Hyman 2012). We aimed to investigate the presence, nature and potential causes of social concerns in children being referred to our national centre with possible CIPO. All patients accepted into the CIPO diagnostic pathway over 3 years (April 2012-April 2015) were reviewed. Acceptance criteria included all of the following (1) referral from a paediatric gastroenterologist or surgeon suspecting a diagnosis of CIPO, (2) mechanical obstruction of the intestine excluded and 3) reliance on specialised enteral or parenteral feeding. The presence and nature of social concerns were recorded pre- & post-assessment along with associated characteristics pertaining to the referral, family situation as well as child protection. Comparison was made to referrals to the IBD service within the department. Of 78 accepted children (mean 5.2 years, 42F) 57 were diagnosed with CIPO, 53 (4.2yrs 31F) by abnormal antroduodenal manometry (ADM) and 4, unsuitable for ADM, by clinical picture. Of the remaining 21 patients (5.8yrs 12F) with normal ADM, 8 were found to have FII; 4 driven by a parent and 4 by the patient (teenage girls). The remaining 13 patients had non-CIPO diagnoses. Of those with normal ADM 17/21 had social concerns; 10 with formal child protection or FII and 7 with concerns over treatment compliance and ambiguity of symptoms. Of those with CIPO 18/57 had social concerns including 2 formally listed as child protection for neglect/parenting concerns and 1 with possible FII. The remaining CIPO cases had a variety of concerns mainly around ambiguity and reliability of reporting. Comparison with a newly diagnosed IBD cohort (161 patients) during the same period revealed only 7 with social concerns. Recurrent themes in those with social concerns, particularly CIPO, included consumerism, internet and media involvement (Facebook, fundraising and celebrity events), resistance to positive news and pain predominant clinical picture. Social concerns (including safeguarding and child protection) in children thought to have CIPO are prevalent (45%) and approximately 10-fold higher than seen in IBD (4.3%). Although commoner in non-CIPO patients, social concerns are also prevalent in those proven to have CIPO (32%). These concerns should be explored and addressed along with an emerging 'profile' of associated risk factors such as use of multi-media, medical consumerism and a pain predominant clinical picture.

To date, there is still uncertainty on the role of specialized intestinal metaplasia in the carcinogenic process of Barrett's oesophagus (BE); this fact seems of importance for planning adequate surveillance programs. To predict the risk of progression towards dysplasia/cancer based on typical morphological features by evaluating the importance of intestinal metaplasia in BE patients. 647 cases with a histological diagnosis of BE, referred to the Endoscopy Unit of a tertiary centre between 2000 and 2012 were retrospectively identified, and divided into two groups according to the presence/absence of intestinal metaplasia. For each patient, all histological reports performed during a follow-up of 4-8 years were analyzed. Overall, 537 cases (83%) with intestinal metaplasia and 110 cases (17%) without intestinal metaplasia were included. During the follow-up period, none of the patients without intestinal metaplasia developed dysplasia/cancer nor progressed to metaplasia, whereas 72 patients with intestinal metaplasia (13.4%) showed histological progression of the disease. The histological identification of intestinal metaplasia seems to be an essential factor for the progression towards dysplasia and cancer in BE patients.

Between January and June, 2015, a large typhoid fever outbreak occurred in Kampala, Uganda, with 10,230 suspected cases. During the outbreak, area surgeons reported a surge in cases of typhoid intestinal perforation (TIP), a complication of typhoid fever. We conducted an investigation to characterize TIP cases and identify modifiable risk factors for TIP. We defined a TIP case as a physician-diagnosed typhoid patient with non-traumatic terminal ileum perforation. We identified cases by reviewing medical records at all five major hospitals in Kampala from 2013 to 2015. In a matched case-control study, we compared potential risk factors among TIP cases and controls; controls were typhoid patients diagnosed by TUBEX TF, culture, or physician but without TIP, identified from the outbreak line-list and matched to cases by age, sex and residence. Cases and controls were interviewed using a standard questionnaire from 1st -23rd December 2015. We used conditional logistic regression to assess risk factors for TIP and control for confounding. Of the 88 TIP cases identified during 2013-2015, 77% (68/88) occurred between January and June, 2015; TIPs sharply increased in January and peaked in March, coincident with the typhoid outbreak. The estimated risk of TIP was 6.6 per 1000 suspected typhoid infections (68/10,230). The case-fatality rate was 10% (7/68). Cases sought care later than controls; Compared with 29% (13/45) of TIP cases and 63% (86/137) of controls who sought treatment within 3 days of onset, 42% (19/45) of cases and 32% (44/137) of controls sought treatment 4-9 days after illness onset (OR adj  = 2.2, 95%CI = 0.83-5.8), while 29% (13/45) of cases and 5.1% (7/137) of controls sought treatment ≥10 days after onset (OR adj  = 11, 95%CI = 1.9-61). 68% (96/141) of cases and 23% (23/100) of controls had got treatment before being treated at the treatment centre (OR adj  = 9.0, 95%CI = 1.1-78). Delay in seeking treatment increased the risk of TIPs. For future outbreaks, we recommended aggressive community case-finding, and informational campaigns in affected communities and among local healthcare providers to increase awareness of the need for early and appropriate treatment.
