    Intestinal obstruction is one of the common surgical emergencies seen in daily practice. Postoperative adhesions are notorious for being the most common cause for intestinal obstruction. Occasionally, laparotomy findings do come as a surprise to surgeons. Here one such case is discussed. A patient was operated on with suspicion of intestinal obstruction secondary to postoperative adhesions. However, laparotomy revealed the appendix to be inflamed, curled around the terminal ileum and acting as a tourniquet. PMID:27437300

    An adult domestic shorthair (DSH) cat was presented with acute vomiting, anorexia, lethargy, and dyspnea. The cat's clinical status worsened over 24 hours with conservative medical management. An exploratory celiotomy was performed. Acute intestinal obstruction resulting from infection with Taenia (T.) taeniaeformis was diagnosed. Surgical removal of the cestodes via multiple enterotomies resolved the obstruction. This paper reports, for the first time, small intestinal obstruction caused by T. taeniaeformis infection in a cat.

    Anisakiasis, a parasitic infection by larvae of the nematode Anisakis found in raw or undercooked saltwater fish, mostly involves stomach but rarely small intestine. We report a rare case of a 61-year-old man who presented with abdominal pain and developed small bowel obstruction caused by intestinal anisakiasis. Abdominal computed tomography revealed segmental edema of the intestinal wall with proximal dilatation. The patient underwent urgent laparotomy because strangulated small bowel obstruction was suspected. A localized portion of the intestine around jejunoileal junction was found to be erythematous, edematous, and hardened, which was resected. The resected specimen showed a linear whitish worm, Anisakis simplex, penetrating into the intestinal mucosa. It is often clinically challenging to consider intestinal anisakiasis in the differential diagnosis because of its nonspecific abdominal symptoms and findings. Although gastrointestinal anisakiasis is still rare in the United States, the incidence is expected to rise given the growing popularity of Japanese cuisine such as sushi or sashimi. Anisakiasis should be considered as one of the differential diagnoses in patients with nonspecific abdominal symptoms after consumption of raw or undercooked fish.

  7. Preduodenal portal vein--a cause of intestinal obstruction?

    A preduodenal position of the portal vein is a rare anomaly reported in 52 cases in the literature. Two additional cases are reported here. In 54% of the cases of preduodenal portal vein (PPV) was combined with high intestinal obstruction and in one half of these cases PPV was considered obstructive. A critical review of these cases given the impression that obstructive PPV could well be a misinterpretation of the obstructive situation and the existence of obstructive PPV is doubted.

    Superior mesenteric artery (SMA) syndrome is an uncommon cause of intestinal obstruction and seldom been mentioned in palliative care. Hereby, we reported a case of SMA syndrome who presented with symptoms of upper intestinal obstruction in a 68-year-old patient; subsequent CT findings were classical of SMA syndrome. The patient's history of poliomyelitis and recent significant weight loss were the predisposing factors for SMA syndrome. It also highlights the importance of monitoring signs and symptoms of intestinal obstruction in such patients before considering switching to oral feeding.

  10. A Rare Type of Primary Internal Hernia Causing Small Intestinal Obstruction

    PubMed Central

    Mohapatra, Vandana; Rath, Pratap Kumar

    2016-01-01

    Primary internal hernias are extremely rare in adults. They are an important cause of small intestinal obstruction and lead to high morbidity and mortality if left untreated. Clinical presentation of internal hernia is nonspecific. Imaging has been of limited utility in cases of acute intestinal obstruction; moreover, interpretation of imaging features is operator dependant. Thus, internal hernias are usually detected at laparotomy and preoperative diagnosis in an emergency setting is either difficult or most of the time not suspected. We report herein a case of a 45-year-old male who presented with acute intestinal obstruction which was attributed later to a very rare type of internal hernia on exploratory laparotomy. A loop of ileum was found to enter the retroperitoneum through a hernia gate which was located lateral to the sigmoid colon in the left paracolic gutter. The segment of intestine was reduced and the hernial defect was closed. Our finding represents an extremely rare variant of retroperitoneal hernias. PMID:27999703

    Patient: Male, 14 Final Diagnosis: Duodenal obstruction Symptoms: Bilious vomiting Medication: None Clinical Procedure: Laparotomy Specialty: Surgery Objective: Rare disease Background: In patients with intestinal malrotation, the diagnosis of acute appendicitis can be difficult due to atypical presentation. Duodenal obstruction caused by acute appendicitis with the presence of malrotation has rarely been reported in children. Case Report: We report the case of a 14-year-old male patient with bilious vomiting and abdominal distension. A diagnosis could not be made by computed tomography, ultrasonography, or endoscopy. We observed a dilated stomach and malrotation in laparotomy. The caecum was in the right upper quadrant, and an inflamed appendix was located in the subhepatic region. After the appendectomy, the cecum was mobilized and fixed in the right lower quadrant. Conclusions: In children with intestinal malrotation, acute appendicitis can present as duodenal obstruction without abdominal pain, and standard imaging methods can miss the correct diagnosis.

    Bezoars are concretions or hard masses of foreign matter that are found in the gastrointestinal tract. Recent reports have demonstrated the efficacy of Coca-Cola administration for the dissolution of phytobezors. Here we report on a 73-year-old man with a very large gastric persimmon diospyrobezoar, and this caused small intestinal obstruction after partial dissolution with oral and injected Coca-Cola.

  14. Congenital Vitelline Band Causing Intestinal Obstruction in an Adult with a Double Inferior Vena Cava

    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.

    Chronic intestinal pseudo-obstruction (CIPO) is a severe digestive syndrome characterized by derangement of gut propulsive motility which resembles mechanical obstruction, in the absence of any obstructive process. Although uncommon in clinical practice, this syndrome represents one of the main causes of intestinal failure and is characterized by high morbidity and mortality. It may be idiopathic or secondary to a variety of diseases. Most cases are sporadic, even though familial forms with either dominant or recessive autosomal inheritance have been described. Based on histological features intestinal pseudo-obstruction can be classified into three main categories: neuropathies, mesenchymopathies, and myopathies, according on the predominant involvement of enteric neurones, interstitial cells of Cajal or smooth muscle cells, respectively. Treatment of intestinal pseudo-obstruction involves nutritional, pharmacological and surgical therapies, but it is often unsatisfactory and the long-term outcome is generally poor in the majority of cases.

    2016-01-01

    Introduction. Intussusception is a rare clinical entity in adults (<1% of intestinal obstructions). Colonic intussusception is even rarer, particularly when caused by lipomas. Case Presentation. A 47-year-old woman presented to our emergency department complaining of abdominal pain with vomiting and diarrhoea. X-ray and CT showed bowel obstruction due to ileocolonic and colocolonic intussusception; a giant colonic lipoma (9 × 4 × 4 cm) was recognizable immediately distally to the splenic flexure of the colon. The patient underwent emergency laparotomy and right hemicolectomy. Assessment of the resected specimen confirmed the diagnosis of giant colonic polypoid lesion near to the ileocecal valve, causing a 12 cm long intussusception with moderate ischemic damage. Conclusion. Colonic obstruction due to intussusception caused by lipomas is a very rare condition that needs urgent treatment. CT is the radiologic modality of choice for diagnosis (sensitivity 80%, specificity near 100%); since the majority of colonic intussusceptions are caused by primary adenocarcinoma, if the etiology is uncertain, the lesion must be interpreted as malignant and extensive resection is recommended. At present, surgery is the treatment of choice and determines an excellent outcome. PMID:28044120

    Extraskeletal osteosarcoma (ESOS) is an uncommon tumor that accounts for 1% of all soft tissue sarcomas and 4% of all osteosarcomas. Its presentation may be atypical, while pain has been described as the most common symptom. Radiological findings include a large mass in the soft-tissues with massive calcifications, but no attachment to the adjacent bone or periosteum. We present the case of a 73-year-old gentle man who presented with a palpable, tender abdominal mass and symptoms of bowel obstruction. Computer tomography images revealed a large space-occupying heterogeneous, hyper dense soft tissue mass involving the small intestine. Explorative laparotomy revealed a large mass in the upper mesenteric root of the small intestine, measuring 22 cm × 12 cm × 10 cm in close proximity with the cecum, which was the cause of the bowel obstruction. Pathology confirmed the diagnosis of an ESOS. ESOS is an uncommon malignant soft tissue tumor with poor prognosis and a 5-year survival rate of less than 37%. Regional recurrence and distant metastasis to lungs, regional lymph nodes and liver can occur within the first three years of diagnosis in a high rate (45% and 65% respectively). Wide surgical resection of the mass followed by adjuvant chemotherapy or radiotherapy has been the treatment of choice. PMID:28289512

    Visceral myopathy is one of the causes of chronic intestinal pseudo-obstruction. Most cases pathologically reveal degenerative changes of myocytes or muscularis propia atrophy and fibrosis. Abnormal layering of muscularis propria is extremely rare. We report a case of a 9-mo-old Thai male baby who presented with chronic intestinal pseudo-obstruction. Histologic findings showed abnormal layering of small intestinal muscularis propria with an additional oblique layer and aberrant muscularization in serosa. The patient also had a short small bowel without malrotation, brachydactyly, and absence of the 2(nd) to 4(th) middle phalanges of both hands. The patient was treated with cisapride and combined parenteral and enteral nutritional support. He had gradual clinical improvement and gained body weight. Subsequently, the parenteral nutrition was discontinued. The previously reported cases are reviewed and discussed.

    We describe the clinicopathologic characteristics of three patients with chronic intestinal pseudo-obstruction and malabsorption. The patients were young women (average age, 25 years) who presented with abdominal pain, nausea, vomiting, diarrhea, and weight loss that led to extreme inanition and death in two patients despite multiple treatment schemes. The evolution of the process averaged 8 years. No case manifested evidence of malignant lymphoproliferative progression. Histologically, a diffuse lymphoplasmacytic infiltrate that affected all the layers of the intestinal wall was observed in full-thickness biopsy specimens. The proliferating lymphocytes were small and mixed with mature plasma cells that proved to be polyclonal on immunohistochemical analysis. An outstanding finding in all three cases was extensive damage to submucosal and myenteric nerve plexus associated with a lymphoid infiltrate. Quantification of the myenteric plexus by using immunohistochemical and morphometric techniques also revealed a marked reduction in their number. We concluded that diffuse lymphoplasmacytic infiltration of the small intestine associated with damage to the intestinal nerve plexus constitutes a specific disorder that is different from other diseases that produce intestinal pseudo-obstruction.

    Chronic intestinal pseudo-obstruction (CIPO) is a syndrome characterized by the presence of recurrent episodes of clinical intestinal obstruction in the absence of obstructive lesions. Although this syndrome is rare, it causes a high morbidity. It is caused by a disturbance of the intestinal motility, that results in a failure of the progression of the intestinal content. Basically, the failure of the intestinal motility is a consequence of muscular disorder, neurological disorder or both. Usually, CIPO is secondary to other systemic disease; however, in the last years, many cases of primary CIPO have been described. The use of new manometric tecniques and specific histological procedures have allowed to clarify the pathogenesis of some of these entities including mitochondrial diseases and paraneoplasic syndromes. Clinical manifestations of CIPO are diverse, depending on the location and extension of the motility disorder. As the diagnosis of this disease is usually not an easy task, patients frecuently undergo unnecesary surgical interventions, are diagnosed of psyquiatric disorders, or the correct diagnosis is delayed several years after the first symptoms arise. The aims of the treatment are to maintain the nutritional condition and to improve symptoms using nutritional measures, drugs or, eventually, endoscopical or surgical procedures.

    Chronic intestinal pseudo-obstruction (CIPO) is a disease characterized by episodes resembling mechanical obstruction in the absence of organic, systemic, or metabolic disorders. Pseudo-obstruction is an uncommon condition and can result from primary (40%) or secondary (60%) causes. The most common symptoms are nausea, vomiting, abdominal distension, abdominal pain and constipation or diarrhea. These symptoms are usually present many years before CIPO diagnosis. They can lead to severe electrolyte disorders and malnutrition. Principles for management of patients with CIPO are: to establish a correct clinical diagnosis in excluding mechanical obstruction; to perform a symptomatic and physiologic assessment of the gastrointestinal tract involved; to look for extra-intestinal manifestations, especially for myopathy and neuropathy; to discuss in some cases a surgery for full-thickness intestinal biopsies, and/or a neuromuscular biopsy in case of mitochondrial cytopathy suspicion. The management is primarily focused on symptom control and nutritional support to prevent weight loss and malnutrition. Treatment of CIPO includes prokinetic agents which may help to reduce gastrointestinal symptoms Courses of antibiotics may be needed in patients with symptoms suggestive of bacterial overgrowth. When necessary, enteral nutrition is preferred. In carefully selected patients, feeding jejunostomy with or without decompression gastrostomy may be tried. Long term parenteral nutrition should be reserved for patients who can not tolerate enteral nutrition. Intestinal transplantation can be discussed in selected patients.

    2013-01-01

    Background Intestinal atresia is a rare congenital disorder with an incidence of 3/10 000 birth. About one-third of patients have severe intestinal dysfunction after surgical repair. We examined whether prenatal gastrointestinal obstruction might effect on the myenteric plexus and account for subsequent functional disorders. Methodology/Principal Findings We studied a rat model of surgically induced antenatal atresia, comparing intestinal samples from both sides of the obstruction and with healthy rat pups controls. Whole-mount preparations of the myenteric plexus were stained for choline acetyltransferase (ChAT) and nitric oxide synthase (nNOS). Quantitative reverse transcription PCR was used to analyze mRNAs for inflammatory markers. Functional motility and permeability analyses were performed in vitro. Phenotypic studies were also performed in 8 newborns with intestinal atresia. In the experimental model, the proportion of nNOS-immunoreactive neurons was similar in proximal and distal segments (6.7±4.6% vs 5.6±4.2%, p = 0.25), but proximal segments contained a higher proportion of ChAT-immunoreactive neurons (13.2±6.2% vs 7.5±4.3%, p = 0.005). Phenotypic changes were associated with a 100-fold lower concentration-dependent contractile response to carbachol and a 1.6-fold higher EFS-induced contractile response in proximal compared to distal segments. Transcellular (p = 0.002) but not paracellular permeability was increased. Comparison with controls showed that modifications involved not only proximal but also distal segments. Phenotypic studies in human atresia confirmed the changes in ChAT expression. Conclusion Experimental atresia in fetal rat induces differential myenteric plexus phenotypical as well as functional changes (motility and permeability) between the two sides of the obstruction. Delineating these changes might help to identify markers predictive of motility dysfunction and to define guidelines for post-surgical care. PMID:23667464

    Chronic intestinal pseudo-obstruction (CIP) is an uncommon disorder that may be of primary or secondary origin. We report a case of a 37-year-old woman with CIP due to inflammatory disorder of unknown origin involving the skin (eosinophilic fasciitis), the lungs (decreased diffusion capacity) and the gastrointestinal tract. History, clinical examination, plain abdominal film, barium X-ray and colonoscopy established a diagnosis of recurrent pseudo-obstruction. A full-thickness biopsy was performed during explorative laparotomy, and histological examination revealed findings compatible with an inflammatory myopathy due to a dense lymphoid infiltrate and extensive loss of the muscularis propria layers. Immunosuppressive therapy with cyclosporin was initiated, with significant clinical improvement. This case illustrates another form of CIP, characterized by an inflammatory myopathy, which is histologically distinct from other known visceral myopathies and neuropathies.

    Intestinal obstruction, revealed by obstruction syndrome, is defined by the cessation of the bowel function whatever the cause. Bowel obstructions are one of the most frequent reasons for hospitalisation in digestive system surgery. They represent a surgical emergency. Diagnosis must enable the obstruction to be confirmed and its mechanisms and location to be specified. The treatment must always include restoring water-electrolyte balance, particularly in elderly people.

    Chronic intestinal pseudo-obstruction(CIPO) is a rare severe digestive disease in which clinical symptoms of intestinal obstruction appear without any mechanical cause. Pathophysiologically, CIPO shows ineffective intestinal propulsion due to an impairment of intestinal smooth muscle, enteric nervous system, and interstitial cells of Cajal(ICC). Sustained increased intra-bowel pressure often causes small intestinal malabsorption and bacterial translocation, and leads to malnutrition and blood stream infection (sepsis). Key points of the medical approach for CIPO are to improve nutritional status and reduce abdominal symptoms. Dietary cure and defecation control are the main options in mild cases, whereas home-parenteral-nutrition(HPN) and decompression therapy are often needed in severe cases. Stimulant laxatives, prokinetics and herbal medicine are usually used but often in fail. Percutaneous endoscopic gastrojejunostomy(PEG-J) tube may be burdenless compared to conventional ileus tube. Most important points in the management of this disease are to make a correct diagnosis as early as possible and avoid unnecessary surgery. However, no clear diagnostic criteria have been established so far. Manometry, scintigraphy, and full-thickness biopsy are the major examination for the CIPO diagnosis in the Western countries; however these specialized examinations are not popular in Japan. Therefore the Research Group(chief investigator, Atsushi Nakajima) proposed Japanese diagnostic criteria in 2009 to facilitate the diagnosis of this rare disease by the general physician. In 2013, we have reported that cine-MRI is a non-invasive diagnostic method for CIPO. Although further data are eagerly awaited, it can become a promising diagnostic tool in CIPO patients. Furthermore the Japanese criteria have been revised, and in 2014, the comprehensive criteria from a child to an adult have been devised. In 2015, CIPO is newly certified as Specified Rare and Intractable Disease which is

Bezoars are responsible for 0.4%-4% of cases of mechanical intestinal obstruction. The clinical findings of bezoar-induced ileus do not differ from those of mechanical intestinal obstruction due to other causes. The appearance and localization of bezoars can be established with various imaging methods. Treatment of choice depends on the localization of the bezoar which makes the clinical findings.

  16. Chronic intestinal pseudo-obstruction.

    2013-06-01

    Chronic intestinal pseudo-obstruction (CIP) is a rare and serious disorder of the gastrointestinal (GI) tract characterized as a motility disorder with the primary defect of impaired peristalsis; symptoms are consistent with a bowel obstruction, although mechanical obstruction cannot be identified. CIP is classified as a neuropathy, myopathy, or mesenchymopathy; it is a neuropathic process in the majority of patients. The natural history of CIP is generally that of a progressive disorder, although occasional patients with secondary CIP note significant symptomatic improvement when the underlying disorder is identified and treated. Symptoms vary from patient to patient depending on the location of the luminal GI tract involved and the degree of involvement; however, the small intestine is nearly always involved. Common symptoms include dysphagia, gastroesophageal reflux, abdominal pain, nausea, vomiting, bloating, abdominal distension, constipation or diarrhea, and involuntary weight loss. Unfortunately, these symptoms are nonspecific, which can contribute to misdiagnosis or a delay in diagnosis and treatment. Since many of the symptoms and signs suggest a mechanical bowel obstruction, diagnostic tests typically focus on uncovering a mechanical obstruction, although routine tests do not identify an obstructive process. Nutrition supplementation is required for many patients with CIP due to symptoms of dysphagia, nausea, vomiting, and weight loss. This review discusses the epidemiology, etiology, pathogenesis, diagnosis, and treatment of patients with CIP, with an emphasis on nutrition assessment and treatment options for patients with nutrition compromise.

  17. Constipation associated with brumation? Intestinal obstruction caused by a fecalith in a wild red diamond rattlesnake (Crotalus ruber).

    This report describes the fecalith-induced intestinal obstruction of a free-ranging red diamond rattlesnake (Crotalus ruber) and the snake's subsequent history following surgical removal of the fecalith. The captured snake exhibited an abnormally distended abdomen and an extremely hard mass, detected via palpation, near its vent. Coeliotomy yielded a 2.5-cm, 5-g fecalith from the large intestine. Microscopic dissection of the fecalith revealed no evidence of gastrointestinal parasitic worms. Subsequently, we implanted a radio-transmitter that allowed us to track the snake's movements for 7 months (until the radio signal vanished), indicating normal behaviour, complete recovery and good health apart from the obstruction. This observation suggests that fecalith development and intestinal obstruction represent potential risks of long-term faecal retention, an unusual physiological trait well documented among rattlesnakes and other stout, heavy-bodied terrestrial viperid snakes. Dehydration and decreased gut motility associated with brumation (≈hibernation) may predispose temperate snakes to fecalith formation. Regional drought and a small mammal diet with indigestible hairs might have also promoted fecalith formation in this specimen.

    Intestinal pseudo-obstruction is a condition characterised by clinical manifestations of mechanical obstruction of the intestine in the absence of any organic occlusion of the lumen. This syndrome has rarely been reported to complicate the course of systemic amyloidosis. We describe the case of a 64-year-old man who presented with the syndrome of small bowel pseudo-obstruction secondary to AL amyloid infiltration of the gastrointestinal tract. We comment on the pathophysiology and on the clinical importance of amyloidosis-associated intestinal pseudo-obstruction.

    The syndrome of intestinal pseudo-obstruction is a complex of signs and symptoms of intestinal obstruction without evidence of mechanical obstruction of the intestinal lumen. A patient with radiation-induced intestinal pseudoobstruction is described. The patient is a 74-year old woman with a history of chronic diarrhea, recurrent episodes of crampy abdominal pain, nausea and vomiting since receiving a 13,000 rad radiation dose to the pelvis in 1954. She has been hospitalized on many occasions for symptoms and signs of bowel obstruction. Upper gastrointestinal contrast roentgenograms with small bowel follow-through done during these episodes revealed multiple dilated loops of small bowel with no obstructing lesion. Barium enemas revealed no obstructing lesion. Each episode resolved with conservative therapy. Other secondary causes for intestinal pseudo-obstruction were ruled out in our patient. She gave no history of familial gastrointestinal disorders. Although postirradiation motility abnormalities have been demonstrated experimentally this is the first report of radiation induced intestinal pseudo-obstruction.

    A bezoar is a concretion of foreign or indigestible matter in the alimentary canal and is usual cause of gastric obstruction. Bezoars can become fragmented and migrate downward leading to intestinal obstruction. Diagnosis of phytobezoar has become challenging in clinical practice due to lack of patient history and inability of patient to correlate preceding events with the episode of bowel obstruction. Bezoar associated small bowel obstruction rarely occurs and is usually found in patients with history of gastrointestinal surgery. Very few cases are reported of small bowel obstruction due to bezoar in healthy population without prior illness or surgery. We present a case of small bowel obstruction due to mushroom bezoar in a 62-year patient with no past history of medical illness or gastric surgery. Enterotomy was performed and a whole piece of undigested mushroom measuring 5 x 3 cm was successfully removed.

    Baclofen is a gamma- aminobutyric acid B (GABA B) agonist used for the management of spasticity associated with spinal cord injury. Oral baclofen might cause constipation, but intestinal pseudo-obstruction is very rare. We report a 50-year-old male with spasticity following cervical discectomy (C3-4) on oral baclofen for 6 months with intestinal pseudo-obstruction. He had undergone open suprapubic cystostomy for traumatic urethral injury, 45 days prior to the presentation and adhesive intestinal obstruction was also considered a possibility. However, there were no air fluid levels on abdominal radiographs and ultrasound abdomen was non-contributory. Withdrawal of baclofen was therapeutic in this patient. This case is being reported to highlight the rare possibility of oral baclofen induced intestinal pseudo-obstruction.

    Chronic intestinal pseudo-obstruction is an uncommon syndrome characterized by relapsing episodes suggesting intestinal obstruction during which no mechanical causes are identified to account for symptoms. Etiologic factors may be manifold. Among them a number of neurologic conditions, gastrointestinal smooth muscle myopathies, endocrino-metabolic and autoimmune diseases, and the use of selected drugs stand out. We report a case of chronic intestinal pseudo-obstruction originating in a sporadic, primary intestinal myopathy that corresponds to no type thus far described. A histological study of the intestinal wall showed disrupted muscle bundles and the presence of interstitial edema. Myocytes had severe degenerative changes, and no alterations were seen in submucosal and myenteric plexus neurons. The activity of enzyme complexes in the mitochondrial respiratory chain, and of thymidine phosphorylase was normal. No mitochondrial DNA changes were seen.

    Context: Bowel obstruction is one of the most common causes of acute abdomen. Because of heterogeneity of patients’ population and variety of causes, therapeutic strategies are not standardized, so treatment of intestinal obstruction is a surgical challenge in many cases. A traditional medicine approach could help detect some issues that were ignored by modern medicine. One of the major schools of medicine, with a history of several thousand years, is Iranian traditional medicine. In this regard, Avicenna, who lived in the medieval period, has had a great influence on the medical knowledge of the world by writing an encyclopedia of medicine entitled “Qanun of Medicine.” Evidence Acquisition: The aim of this study was to investigate Avicenna’s views on the causes of intestinal obstruction and comparing them to modern medicine views. This is a review study on an Iranian traditional textbook of medicine by Avicenna, entitled “Qanun of Medicine” (in short “Qanun”). We used Qanun in its original language (Arabic) along with its Persian translation. It consists of 5 books. Part 16 of the third book talks about intestinal anatomy and introduces some intestinal diseases such as “qoolinj” and “ilavos.” Intestinal obstruction can be a kind of “qoolinj” or “ilavos” disease. All intestinal obstruction etiologies in Qanun are searched in international and Iranian databases (Scopus, ISI, SID, and Iranmedex) and similar causes in modern medicine will be discussed in this article. Results: According to Qanun, 16 causes are involved in intestinal etiologies of bowel obstruction such as “reeh,” mucoid phlegm, abdominal hot and dry distemperament, decreased bile secretion, job, and so on while modern medicine considers some of them, for instance, volvulus, intestinal herniation, worm, intestinal pseudo-obstruction, and opiate. Conclusions: Attention to the similar causes of intestinal obstruction in modern medicine and traditional medicine is the

    Lymphocytic intestinal leiomyositis is a rare entity, which causes chronic intestinal pseudo-obstruction (CIPO) in children. We present the first case of a boy who had pure red cell anemia 1 year before onset. Prolonged ileus developed after gastroenteritis and the patient was diagnosed using a biopsy of the intestinal wall. Findings from the present case indicate that there are three important factors for accurate diagnosis: history of enteritis, positive serum smooth muscle antibody, and lymphocyte infiltration with muscle destruction in the muscularis propria in the intestinal wall. Earlier diagnosis and induction of immunosuppressive therapy may be essential for a better outcome.

Here, we report a case of intestinal obstruction due to a clinical thermometer which migrated from the bladder into the abdominal cavity. A 45-year-old man was admitted to our hospital with a one-year history of recurrent lower abdominal cramps. Two days before admission, the abdominal cramps aggravated. Intestinal obstruction was confirmed with upright abdominal radiography and computerized tomography scan which showed dilation of the small intestines and a thermometer in the abdominal cavity. Then laparotomy was performed. A scar was observed at the fundus of the bladder and a thermometer was adhering to the small bowels and mesentery which resulted in intestinal obstruction. Abdominal cramps were eliminated and defecation and flatus recovered soon after removal of the thermometer. PMID:24605042

    Chronic idiopathic intestinal pseudo-obstruction is a rare and serious chronic disease starting in childhood, which can affect the entire digestive tract. It is caused by a peristalsis intestinal disorder that leads to occlusions without any obvious obstruction. Few studies have been carried out regarding the prognosis of this illness. This disease is often diagnosed by a process of elimination, but some histological anomalies have been present in the digestive wall of certain patients. This clinical case concerns a 17-year-old girl affected by CIPO and eating disorders. It seems difficult to discriminate between digestive disorders and eating disorders. What psychological effects can this severe pathology have? Are eating disorders induced by CIPO? These questions are raised in this article through the example of this patient's somatopsychic complexity and the ensuing difficulties in her overall care.

    The most serious consequences of infection with the large roundworm, Ascaris lumbricoides, are complications requiring surgical intervention, particularly intestinal obstruction caused by a bolus of worms. A study was conducted to estimate the incidence of this complication among infected children in an area of the southeastern United States where ascariasis is endemic. A chart review at three rural Louisiana public hospitals revealed that 21 patients had been hospitalized with intestinal obstruction secondary to ascariasis over a 3-year period. The prevalence of ascariasis in three parishes (counties) served by these hospitals was calculated from the results of 2,360 stool examinations performed by the State Health Department and one hospital laboratory. The prevalence of ascariasis in 1- to 5-year-old children was similar to that in 6- to 12-year-olds and ranged from 8% to 28% in the three parishes. Prevalence rates were three times higher for blacks than for whites. It was found that most cases of intestinal obstruction occur in children in the 1- to 5-year age group and that this incidence approximates two such complications per 1,000 infected children per year.

    Intestinal obstruction in pregnancy is rare and is mainly caused by prior pelvic surgery. We herein report a case of intestinal obstruction in a pregnant female with a history of laparoscopic myomectomy, who presented with hypogastric pain, abdominal distension, and vomiting at 26 weeks of gestation. A simple intestinal obstruction was diagnosed by MRI. Conservative treatments, including intravenous hyperalimentation and the placement of an ileus tube, were provided and her abdominal symptoms improved for 14 days. After restarting oral intake, she had no abdominal symptoms. She gave birth to a 2,146 g female infant by caesarean section at 37 weeks and 1 day of gestation. Although an area of cicatrization, which was thought to have been the starting point of the occlusion that caused the intestinal obstruction, was found, the excision of the small intestine was not necessary. Her postoperative course was uneventful. Intestinal obstruction requires a prompt diagnosis and aggressive intervention may be necessary to minimize the morbidity and mortality associated with this rare complication of pregnancy. MRI can be safely used during pregnancy to diagnose intestinal obstruction and intravenous hyperalimentation may improve the maternal and fetal prognoses. PMID:27999695

    2013-12-01

    Intestinal pseudo-obstruction is a rare and relatively unknown complication of phaeochromocytoma÷ paraganglioma (PCC÷PGL). Its pathophysiology can be explained by the hypersecretion of catecholamines, which may reduce the peristaltic activity of the gastrointestinal tract. Clinically, this can result in chronic constipation, intestinal pseudo-obstruction or even intestinal perforation. We conducted a comprehensive literature search and retrieved 34 cases of pseudo-obstruction caused by either benign or malignant PCC÷PGL. We also included a case from our centre that has not been described earlier. We conclude that intestinal pseudo-obstruction is a rare but potentially life-threatening complication of PCC÷PGL. Intravenous administration of phentolamine is the most frequently described treatment when surgical resection of the PCC÷PGL is not feasible.

    The treatment of intestinal obstruction (IO) in patients with advanced or terminal cancer represents an open and widely discussed topic in clinical oncology practice. As surgical palliation is a complex issue, the decision to advance with surgery should be made in consultation with the patients and family members. The prognostic factors, mainly the survival time and the surgical risks can be considered guideline indicators. If there is any possibility that surgery will be of benefit, the patient should be treated with intravenous fluids and nasogastric suction while appropriate radiological investigations are performed. When surgical intervention is contraindicated, symptomatic medical treatment should be started through continuous subcutaneous administration of analgesic and antiemetic drugs. Minor episodes of vomiting may occur, which do not trouble patients since the most distressing symptom, nausea, can be controlled. Dehydration may be avoided with a liquid diet in small quantities. In this way, it is possible to manage patients with IO for several weeks without the need of nasogastric suction or intravenous fluids. Percutaneous gastrostomy, nasogastric tube, or hypodermoclysis may be necessary for a small number of patients, principally with high obstruction, who have refractory symptoms.

    Abstract Background: Appendiceal mucinous cystadenoma can present in various ways, and it is most commonly encountered incidentally during appendectomy, but mechanical intestinal obstruction secondary to an appendiceal mucocele has been rarely reported. Methods: We report a case of mechanical intestinal obstruction secondary to appendiceal mucinous cystadenoma. After nasogastric decompression and initial aggressive intravenous fluid resuscitation, an emergency operation was performed under the diagnosis of acute mechanical intestinal obstruction. Results: We performed an appendectomy and intraoperative enteral decompression without anastomoses. The pathologic examination (PE) revealed appendiceal mucinous cystadenoma. After the operation, the patient's recovery went smoothly, and the patient was discharged on the fifth postoperative day. No tumor recurrence was recorded over an 8 month follow-up period. Conclusion: Early operative intervention should be recommended to the patient with acute mechanical complete intestinal obstruction, especially the patient who had no previous abdominal surgery. And it is vital to discriminate benign and malignantappendiceal mucocel in determining the extent of surgery. PMID:28151903

    Chronic intestinal pseudo-obstruction represents a cause of persistent functional intestinal failure either "secondary" to specific conditions or "chronic intestinal idiopathic pseudo-obstruction" in origin. The diagnosis is mainly clinical, supported by radiological and/or endoscopic findings excluding any mechanical cause of intestinal obstruction. We reported a case of a 39-year-old woman with chronic intestinal idiopathic pseudo-obstruction, who underwent colectomy with ileorectal anastomosis; histological examination of the surgical specimen did not reveal myogenic or neurogenic defects or other pathological abnormalities indicative of an underlying neuromuscular impairment. Because of the apparent integrity of the gut neuromuscular layer, we tested whether a functional impairment affected colonic single smooth muscle cells. Muscle cells were isolated from the right colon and their contractile response to a receptor-dependent agonist evaluated in comparison to that obtained from controls. The cell contraction induced by acetylcholine in a dose response manner was markedly decreased in the patient affected by chronic intestinal idiopathic pseudo-obstruction compared with cells from controls (percentage of cell shortening with maximal dose of acetylcholine [10(-6)M]: 10.7+/-3% versus 34.2+/-4%, respectively). The present findings indicate a specific defect of colonic smooth muscle cells likely related to an ineffective response to acetylcholine.

    Intestinal obstruction is associated with significant morbidity and mortality. Scientific assessment of the cause, site of obstruction, appropriate correction of the fluid deficit and electrolyte imbalance with preoperative stabilization of blood gases is ideal as a preoperative workup. Placement of a preoperative epidural catheter especially in the thoracic interspace takes care of perioperative pain and stress reduction. Intraoperative management by controlled general anesthesia administering a relative high inspired fraction of oxygen with invasive monitoring in selected sick cases is mandatory. Preoperative monitoring and stabilizing raised intra-abdominal pressure reduces morbidity. Caution should be exercised during opening and closure of abdomen to avoid cardiorespiratory ill effects. There should be an emphasis on avoiding hypothermia. The use of nonsteroidal anti-inflammatory drugs may worsen sick, fragile patients. The use of sugammadex rather than neostigmine will obscure certain controversies in the healing of intestinal anastomotic site. Replacement of blood loss continued correction of fluids and electrolytes with possible postoperative mechanical ventilation in sick cases may improve outcomes in these patients. PMID:27746522

    Chronic intestinal pseudoobstruction (CIPO) is a rare entity characterized by recurrent clinical episodes of intestinal obstruction in which no mechanical cause is identified. There are multiple causes for this syndrome but two main groups can be distinguished: a) secondary to a systemic non-gastrointestinal disease; and b) primary or idiopathic originated from alterations in the components of the intestinal wall. The latter forms are the most uncommon and their diagnosis is generally difficult. In the present article, we describe nine patients with CIPO that were diagnosed in our center over the last six years. Four of them were diagnosed with primary or idiopathic form of CIPO and another four were clearly secondary to a systemic disease. The ninth case, which was initially diagnosed as secondary, is probably also a primary form of the disease. The number of patients diagnosed in our center, even thought small, makes us to hypothesize that the prevalence of CIPO is probably greater than is generally believed and that the reasons of its rarity are the incomplete understanding of its physiopathology and the difficulties to achieve a correct diagnosis.

    Strongyloides stercolaris infestation is rather rare in Iraq. Individuals with infection confined to the intestinal tract are often asymptomatic. Symptoms include abdominal pain, diarrhea, weight loss and other non-specific complaints. The diagnosis depends upon repeated examination of stool and duodenal aspirate. Two cases presenting as sub-acute intestinal obstruction and mimicking primary intestinal lymphoma (PIL) on presentation are presented. Differentiation between the two conditions regarding presenting features, barium studies and pathology are discussed.

  10. Encountering Meckel's diverticulum in emergency surgery for ascaridial intestinal obstruction

    PubMed Central

    2010-01-01

    Background Meckel's diverticulum is the most common congenital anomaly of the gastrointestinal tract. In children with intestinal ascariasis, the diverticulum remains asymptomatic or rarely the Ascaris lumbricoides may lead to its complications in the presence of massive intestinal roundworm load. Given that preoperative diagnosis is seldom carried out, when Meckel's diverticulum is found at laparotomy for obstructive intestinal complications of roundworm, the diverticulum should be removed as complications may occur at any time. The aim of this study was to describe the findings of concomitant presence of Meckel's diverticulum who had surgical intervention in symptomatic intestinal ascariasis in children. Methods A retrospective case review study of 14 children who had surgical intervention for symptomatic intestinal ascariasis having the presence of concomitant Meckel's diverticulum was done. The study was done at SMHS Hospital Srinagar, Kashmir. Results A total of the 14 children who had ascaridial intestinal obstruction with concomitant presence of Meckel's diverticulum were studied. Age of children ranged from 4-12 years, male:female ratio was 1.8:1. Nine patients had asymptomatic Meckel's diverticulum, whereas 5 patients with symptomatic signs were found in the course of emergency surgery for ascaridial intestinal obstruction. Conclusion Meckel's diverticulum in intestinal ascariasis may pursue silent course or may be accompanied with complications of the diverticulitis, perforation or the gangrene. Incidental finding of the Meckel's diverticulum in the intestinal ascariasis should have removal. PMID:20529382

    ABSTRACT Strangulated intestinal obstruction is one of the most common types of acute abdomen and requires urgent surgical treatment. Herein, we report a very rare case of strangulated intestinal obstruction caused by an ileo-ileal knot. An 80-year-old woman was admitted to our hospital with suspicion of strangulation ileus and underwent emergency laparotomy after investigation by exploratory single-port laparoscopy. During surgery, a small bowel gangrene caused by an ileo-ileal knot was found. The gangrenous segment was resected, and primary anastomosis was performed. Post-operative recovery was uneventful except for a minor wound infection. Our extensive search of the literature found only 7 case reports of ileo-ileal knot including ours. An ileo-ileal knot should be considered in the differential diagnosis of acute intestinal obstruction, because this rare phenomenon requires urgent surgical treatment; and some complications should be considered during or after surgery.

    Introduction Small bowel obstruction in a virgin abdomen is an uncommon surgical condition. While malignancy, inflammatory bowel disease and foreign body are the main reported causes, undigested food bezoar causing bowel obstruction is a rare entity. We report a case of small bowel obstruction secondary to dried preserved apple having re-expanded within the gastrointestinal tract. Presentation of case A 69 year old male presented with severe abdominal distension, generalized abdominal tenderness and obstipation for 1 week. Small bowel obstruction (SBO) was confirmed on plain abdominal X-ray and CT imaging. An emergency explorative laparatomy identified a sausage-shaped intra-luminal foreign body obstructing the distal ileum. An enterotomy was performed which revealed a rehydrated, donut-shaped piece of dried apple. Discussion Swallowed items that pass through the pylorus rarely cause obstruction as they are usually small enough to pass through the rest of the bowel without difficulty. We postulate that in our patient that the dried apple was originally small enough to pass through the pylorus. However during small bowel, its’ highly absorbable nature resulted in an increase in size that prevented its’ passage through the ileocecal valve. A simple in-vitro experiment discovered that dried apple has a potential to reabsorb fluid and expand up to 35% of its initial size within 72 h. Conclusion This report illustrates the potential for dried food substances to cause intra-luminal SBO after significant expansion with rehydration. PMID:25841159

    Myeloid sarcoma is an extramedullary collection of blasts of the myeloid series that partially or totally effaces the architecture of the tissue in which it is found. These tumors have been described in many sites of the body, but the skin, lymph nodes, gastrointestinal tract, bone, soft tissue, and testes are most common. They can arise in a patient following the diagnosis of acute myeloid leukemia, but they may also be precursors of leukemia and should be considered diagnostic for acute myeloid leukemia. The differential diagnosis of this neoplasm includes malignant lymphoma, with which it is often mistaken, leading to diagnostic and therapeutic delays. We present the case of an 84-year-old African American man with a history of renal disease secondary to hypertension and coronary artery disease without any prior history of malignancies who presented with airway obstruction. He was diagnosed with a myeloid sarcoma of the mediastinum compressing his trachea.

    Paraneoplastic syndromes can precede the initial manifestation and diagnosis of cancer. Paraneoplastic syndromes are a heterogeneous group of disorders caused by mechanisms other than the local presence of tumor cells. These phenomena are mediated by humoral factors secreted by tumor cells or by tumor mediated immune responses. Among paraneoplastic syndromes, chronic intestinal pseudo-obstruction (CIPO) is rare and represents a particularly difficult clinical challenge. Paraneoplastic CIPO is a highly morbid syndrome characterized by impaired gastrointestinal propulsion with symptoms and signs of mechanical bowel obstruction. Clinical outcomes of paraneoplastic CIPO are often deleterious. The current standard of care for the management of CIPO includes supportive treatment with promotility and anti-secretory agents. However, the majority of patients with CIPO eventually require the resection of the non-functioning gut segment. Here, we present a 62-year-old patient with anti-Hu antibody associated paraneoplastic CIPO and underlying small cell lung cancer who underwent treatment with cisplatin and etoposide. Herein, we discuss diagnosis, prognosis, proposed mechanisms, treatment options, and future potential therapeutic strategies of paraneoplastic CIPO.

    Intestinal obstruction belongs to highly severe conditions in gastroenterology, namely from the viewpoint of quick and correct diagnosis as well as at determining rational and effective therapy. Etiological multifactorial characteristics leading to processes resulting in mechanical or dynamic obstruction of the intestine, often referred to as paralytic ileus, are undoubtedly serious factors influencing the accuracy of diagnosis and therapeutic approach. Digestive endoscopy is a mandatory method in the diagnosis of intestinal obstructions. Diagnostic endoscopy, colonoscopy in the involvement of the large intestine or enteroscopy in the case of incomplete obstruction of the small intestine are the methods indicated in the majority of obstructive intestinal lesions. Besides their diagnostic importance, they also enable an effective therapeutic approach which may immediately follow the diagnostic intervention. Besides endoscopy that--due to the nature of performance--belongs to invasive methods, the diagnosis of obstructive intestinal processes is unthinkable without the use of non-invasive imaging methods. Abdominal ultrasound examination, a widely applied method, provides--under optimal examination conditions--information, e.g., about the width of the intestinal lumen or about the intestinal wall thickness; however, the specificity of investigation is not always sufficient. Both specificity and sensitivity of exploration are increased by a plain X-ray of the abdomen supplementing the ultrasound examination. Better results are achieved when the abdominal cavity is inspected by means of spiral CT examination that is nowadays not fashionable but highly effectively applied in the modification of the so-called CT enteroclysis or CT colonography. The usage of magnetic resonance (e.g. virtual colonography) is similar, but its efficacy is lower than that of CT examination. From a gastroenterologist's perspective, endoscopic examination is the fundamental diagnostic and

    Abstract Ventriculoperitoneal (VP) shunt complications are common, but abdominal complications are rare. The objective of this report is to present 2 cases of intestinal obstruction due to a VP shunt and review the literature for data on this rare occurrence. A 4-month-old boy received surgical resection of a medulloblastoma and a VP shunt was inserted to manage progressive hydrocephalus. Two months later, he was admitted with intermittent vomiting, and plain abdominal radiography showed complete intestinal obstruction. Emergency laparotomy revealed an adhesive intestinal obstruction around the catheter, and approximately 5 cm of necrotic ileum was resected. His recovery was uneventful. In the second case, a 6-year-old boy was diagnosed with a primary nongerminomatous malignant germ cell tumor and a VP shunt was place to treat hydrocephalus. Two weeks after the first course of chemotherapy, he went into a coma; computed tomography demonstrated enlargement of the tumor and gross total resection was performed. Two weeks later, he developed abdominal distention; plain radiography showed intestinal obstruction and laparotomy revealed adhesive intestinal obstruction around the catheter with 15 cm of necrotic ileum. The necrotic bowel was resected. Unfortunately, the patient developed sepsis and despite treatment remained in a vegetative state. Medline, Central, Embase, and Google Scholar databases were searched up to May 9, 2014, using the terms VP shunt, shunting, and/or intestinal obstruction. Only cases involving children or adolescents were included. Eleven reports involving patients with abdominal complications resulting from a VP shunt for hydrocephalus were identified. The dates of the reports spanned from 1971 to 2014. Volvulus was the most common cause of VP shunt-related obstruction, and mechanical obstruction due to twisting of the catheter the second most common. Only 1 case in the literature review was related to intestinal adhesions. Treatment in most

    Partial obstruction of the small intestine causes obvious hypertrophy of smooth muscle cells and motility disorder in the bowel proximate to the obstruction. To identify electric remodeling of hypertrophic smooth muscles in partially obstructed murine small intestine, the patch-clamp and intracellular microelectrode recording methods were used to identify the possible electric remodeling and Western blot, immunofluorescence and immunoprecipitation were utilized to examine the channel protein expression and phosphorylation level changes in this research. After 14 days of obstruction, partial obstruction caused obvious smooth muscle hypertrophy in the proximally located intestine. The slow waves of intestinal smooth muscles in the dilated region were significantly suppressed, their amplitude and frequency were reduced, whilst the resting membrane potentials were depolarized compared with normal and sham animals. The current density of voltage dependent potassium channel (KV) was significantly decreased in the hypertrophic smooth muscle cells and the voltage sensitivity of KV activation was altered. The sensitivity of KV currents (IKV) to TEA, a nonselective potassium channel blocker, increased significantly, but the sensitivity of IKv to 4-AP, a KV blocker, stays the same. The protein levels of KV4.3 and KV2.2 were up-regulated in the hypertrophic smooth muscle cell membrane. The serine and threonine phosphorylation levels of KV4.3 and KV2.2 were significantly increased in the hypertrophic smooth muscle cells. Thus this study represents the first identification of KV channel remodeling in murine small intestinal smooth muscle hypertrophy induced by partial obstruction. The enhanced phosphorylations of KV4.3 and KV2.2 may be involved in this process.

    Sarcoidosis is a systemic granulomatous disease of unknown etiology, characterized by the formation of noncaseating granulomas. Gastrointestinal (GI) system involvement that is clinically recognizable occurs in less than 0.9% of patients with sarcoidosis, with data revealing small intestine involvement in 0.03% of the cases. A high index of suspension is required in patients presenting with small-bowel obstruction and previous history of sarcoidosis. Establishing a definitive diagnosis of GI sarcoidosis depends on biopsy evidence of noncaseating granulomas, exclusion of other causes of granulomatous disease, and evidence of sarcoidosis in at least one other organ system. Treatment of GI sarcoidosis depends on symptomatology and disease activity. Herein, we are presenting a case of 67-year-old female patient who had acute small-bowel obstruction at the level of jejunum with postoperative histopathologic evidence of noncaseating granulomatous inflammation with multinucleated giant cells, consistent with sarcoidosis.

    Paraneoplastic neurologic syndromes (PNS) are uncommon, affecting fewer than 1 in 10,000 patients with cancer. PNS, while rare, can cause significant morbidity and impose enormous socio-economic costs, besides severely affecting quality of life. PNS can involve any part of the nervous system and can present as limbic encephalitis, subacute cerebellar ataxias, opsoclonus-myoclonus, retinopathies, chronic intestinal pseudo-obstruction (CIPO), sensory neuronopathy, Lambert-Eaton myasthenic syndrome, stiff-person syndrome, and encephalomyelitis. The standard of care for CIPO includes the use of promotility and anti-secretory agents and the resection of the non-functioning gut segment; all of which can cause significant compromise in the quality of life. There is significant evidence that paraneoplastic neurologic syndromes are associated with antibodies directed against certain nerve antigens. We successfully treated a patient with CIPO in the setting of small cell lung cancer with a combination of rituximab and cyclophosphamide. The patient, who had failed to respond to prokinetic agents, anti-secretory therapy, and multiple resections, responded to the immunomodulatory therapy, with minimal residuals with PEG tube feeding and sustained ostomy output. The use of rituximab and cyclophosphamide should therefore be considered in patients with CIPO, especially if it can avoid complicated surgical procedures.

    Phytobezoar is an unusual cause of small bowel obstruction. It accounts for about 0.4%-4% of all mechanical bowel obstruction. However, the symptoms are not very different from those caused by usual aetiologies of small bowel obstruction. The commonest site of obstruction is terminal ileum. Treatment of small bowel obstruction due to Phytobezoar is surgery. Prevention includes avoidance of high fibre diet, prokinetics particularly in patients who have undergone gastric surgery. A 57-year-old male presented with symptoms and signs of small bowel obstruction. On exploratory laparotomy Phytobezoar in the ileum was found to be the cause of obstruction. Diagnosis was confirmed by histopathology.

    Objective Benign nodular goiter (BNG) can cause narrowing of the upper airway. In some rare cases, obstruction of the upper airway also occurs. The following paper reports our experiences with regard to BNG patients who experienced obstruction of the upper airway. Materials and Methods. We retrospectively investigated the records of 13 patients with acute airway obstruction due to BNG who were admitted to the General Surgery Department of Ataturk University Medical School between January 2000 and December 2007. Results Thirteen patients with airway obstruction secondary to BNG were hospitalized during this period. There were two males and 11 females, and the mean age was 58.5 years (range 37–74 years). For all patients, the primary symptom upon admission was defined as respiratory distress; all patients had varying degrees of respiratory distress upon admission. Three of the patients underwent emergent endotracheal intubation in the emergency room. A preoperative radiological evaluation was performed with thyroid ultrasonography (US) and computed tomography (CT). There were retrosternal or substernal components of the BNG in nine patients. Twelve patients underwent operations, while one patient with mild respiratory distress elected not to be operated on. Ten patients underwent total thyroidectomies, while two patients underwent near-total thyroidectomies. One patient with retrosternal goiter also underwent a median sternotomy. Three patients received a tracheostomy after the operation. Suction drains were utilized in all operations. During the post-operative period, two patients suffered from voice impairment, and seven patients experienced hypocalcemia. Two patients died. Pathological examination of the thyroidectomy tissue revealed BNG in all cases. In addition, two patients had micropapillary carcinomas. Conclusion Although BNG causing upper airway obstruction is rare, it is an important clinical entity because of the need for emergent operation, the

    Increased amounts of intestinal endotoxin are absorbed in obstructive jaundice. The precise mechanism is not known but the increased absorption may arise from alterations in the luminal contents, in the intestinal flora, in the gut wall or in interactions between all three. To examine the effects of the intestinal flora we have compared the morphological changes in the small intestine in obstructive jaundice in germ free and conventional rats while the effects of bile constituents have been examined by addition of bile constituents to the diet of bile duct ligated rats. Changes in the intestine were examined, histologically, by enzyme histochemistry, and by transmission and scanning electron microscopy. The results showed no differences in response between germ free and conventional rats. Feeding of diets containing bile salts exacerbated the lesion. Feeding of diets containing cholesterol, however, reduced the degree of intestinal changes produced by cholestasis and completely antagonised the increase in damage caused by feeding of bile salts.

    Intestinal pseudo-obstruction is more commonly known in its chronic form (CIPO), a cluster of rare diseases characterized by gastrointestinal muscle and nerve impairment, so severe to result in a markedly compromised peristalsis mimicking an intestinal occlusion. The management of CIPO requires the cooperation of a group of specialists: the disease has to be confirmed by a number of tests to avoid mistakes in the differential diagnosis. The treatment should be aimed at relieving symptoms arising from gut dysmotility (ideally using prokinetic agents), controlling abdominal pain (possibly with non-opioid antinociceptive drugs) and optimizing nutritional support. Furthermore, a thorough diagnostic work-up is mandatory to avoid unnecessary (potentially harmful) surgery and to select patients with clear indication to intestinal or multivisceral transplantation.

    Chronic intestinal pseudo-obstruction (CIPO), one of the most severe gastrointestinal motility disorders, is a condition characterized by a clinical picture mimicking small bowel occlusion with related symptoms and signs in the absence of demonstrable mechanical obstruction. Analysis of full-thickness biopsy samples may unravel structural changes of the neuromuscular layer involving the whole gut, although the midgut is usually worst affected. Intestinal pseudo-obstruction can occur in association with systemic neurological, endocrine, and connective tissue diseases or malignancy but, when no recognizable etiology is found, CIPO is referred to as idiopathic (CIIPO). The latter form can be diagnosed early in life due to a genetic etiology or in adulthood when a viral origin may be considered. This review addresses the hypothesis that some systemic neurotrophic viral infections can affect the enteric nervous system thereby altering normal peristaltic activity. Available data are reviewed, focusing specifically on herpesviruses or polyomaviruses (JC virus). These suggest that in comparison to a proportion of CIIPO patients, healthy controls rarely harbor viral DNA in the myenteric plexus, leaving open the possibility that a viral infection might have an etiologic role in the development of CIIPO. The review thus provides some new perspectives in the pathophysiology and perhaps targeted treatment of CIIPO.

On exploration she was found to have an obstructed obturator hernia, which is a rare pelvic hernia with an incidence of 0.07-1.4% of all intra-abdominal hernias. Diagnosis is often delayed until laparotomy for bowel obstruction. Strangulation is frequent and mortality remains high (25%). Early diagnosis and surgical treatment contributes greatly to reduce the mortality and morbidity rates. A variety of techniques have been described, however surgical repair has not been standardized. It is an important diagnosis to be considered in elderly patients with intestinal obstruction. PMID:27763487

    INTRODUCTION Internal abdominal hernias are infrequent but an increasing cause of bowel obstruction still often underdiagnosed. Among adults its usual causes are congenital anomalies of intestinal rotation, postsurgical iatrogenic, trauma or infection diseases. PRESENTATION OF CASE We report the case of a 63-year-old woman with history of chronic constipation. The patient was hospitalized for two days with acute abdominal pain, abdominal distension and inability to eliminate flatus. The X-ray and abdominal computerized tomography scan (CT scan) showed signs of intestinal obstruction. Exploratory laparotomy performed revealed a trans-mesenteric hernia containing part of the transverse colon. The intestine was viable and resection was not necessary. Only the hernia was repaired. DISCUSSION Internal trans-mesenteric hernia constitutes a rare type of internal abdominal hernia, corresponding from 0.2 to 0.9% of bowel obstructions. This type carries a high risk of strangulation and even small hernias can be fatal. This complication is specially related to trans-mesenteric hernias as it tends to volvulize. Unfortunately, the clinical diagnosis is rather difficult. CONCLUSION Trans-mesenteric internal abdominal hernia may be asymptomatic for many years because of its nonspecific symptoms. The role of imaging test is relevant but still does not avoid the necessity of exploratory surgery when clinical features are uncertain. PMID:24880799

    Intestinal pseudo-obstruction (IPO) is an uncommon and severe complication of systemic lupus erythematosus (SLE). We report a 24-year-old female with a 2 year SLE duration who presented with abdominal pain, vomiting, constipation and abdominal distention. Plain abdominal radiograph showed multiple air-fluid levels of the small bowel. Computed tomographic scan of the abdomen revealed dilated small bowel loops without mechanical obstruction. Urinary tract involvement was also demonstrated. IPO was diagnosed and the patient responded well to immunosuppressive treatment. IPO is a recently recognized manifestation of SLE that may be the presenting manifestation of the systemic disease or occur more commonly during disease course. Early recognition of IPO is necessary to institute appropriate medical treatment and to avoid inappropriate surgical intervention.

An abdominal radiograph showed diffuse small bowel distension containing multiple air-fluid levels and extensive calcifications along the colon. Computed tomography showed colon wall thickening with diffuse calcification along the colonic mesenteric vein and colonic wall. Colonoscopy, performed without bowel preparation, showed bluish edematous mucosa from the transverse to the distal sigmoid colon, with multiple scar changes. At the mid transverse colon, a stricture was noted and the scope could not pass through. A biopsy of the stricture site revealed nonspecific changes. The patient was diagnosed with phlebosclerotic colitis. After the colonoscopy, the obstructive ileus spontaneously resolved, and the patient was discharged without an operation. Currently, after 2 months of follow-up, the patient has remained asymptomatic. Herein, we report the rare case of an obstructive ileus caused by phlebosclerotic colitis with a colon stricture.

    Background. Acute intestinal obstruction during pregnancy is a very challenging and unusual nonobstetric surgical entity often linked with considerable fetomaternal morbidity and mortality. When it is synchronous with abdominal pregnancy, it is even rarer. Case Presentation. A 28-year-old lady in her second pregnancy was referred to Nnamdi Azikiwe University Teaching Hospital, Nnewi, Nigeria, at 27 weeks of gestation due to vomiting, constipation, and abdominal pain. Examination and ultrasound scan revealed a single live intra-abdominal extrauterine fetus. Plain abdominal X-ray was diagnostic of intestinal obstruction. Conservative treatment was successful till the 34-week gestational age when she had exploratory laparotomy. At surgery, the amniotic sac was intact and the placenta was found to be adherent to the gut. There was also a live female baby with birth weight of 2.3 kg and Apgar scores of 9 and 10 in the 1st and 5th minutes, respectively, with the baby having right clubbed foot. Adhesiolysis and right adnexectomy were done. The mother and her baby were well and were discharged home nine days postoperatively. Conclusion. To the best of our knowledge, this is the first report of abdominal pregnancy as the cause of acute intestinal obstruction in the published literature. Management approach is multidisciplinary.

    Background: Gastrointestinal tract (GIT) duplications are one of the rare congenital anomalies and can occur in any portion of the gastrointestinal tract but are more commonly encountered in small intestine. The duplication cysts cause symptoms like abdominal mass and intestinal obstruction requiring surgery or may remain asymptomatic. We are reporting our 15 years’ experience duplication cysts presenting in neonates. Methods: It is a retrospective study undertaken in the department of pediatric surgery between 2001 and 2015 for GIT duplications in neonates. Patients were analyzed for their antenatal diagnosis, age, sex, clinical diagnosis, investigatory approach, operative management and surgical outcomes. Results: Total number of neonates, diagnosed with gastrointestinal duplication in the last 15 years, was 17. Male to female ratio was 3.3:1. The most common location was found to be the ileum occurring in 71% of cases. Apart from ileum, 2 cases of duodenal and 1 case each of gastric, colonic and cecal duplication cyst were encountered. Majority cases presented with sub-acute intestinal obstruction and were managed successfully by resection and end to end anastomosis. Associated gut atresia was found in 4 cases while 1 case was found to be associated with perforation of gut. Conclusion: Gastrointestinal tract duplications often present with typical symptoms of gastrointestinal tract obstruction. Early diagnosis and management is required to prevent postoperative morbidity and mortality. PMID:28083491

    Chronic intestinal pseudo-obstruction (CIPO) is a rare disease due to a severe gastrointestinal motility disorder which may mimic, on both clinical and radiological grounds, mechanical obstruction. We report a case of a 26-year-old woman who presented to our institution for plain abdominal radiography for referred long-lasting constipation with recurrent episodes of abdominal pain and distension. At X-ray, performed both in the upright and supine position, an isolated air-fluid level was depicted in the left flank, together with a number of radiological signs suggestive of pneumoperitoneum. First, subphrenic radiolucency could be observed in the upright film. Second, the intestinal wall of some jejunal loops appeared to be outlined in the right flank. Third, the inferior cardiac border was clearly depicted in the upright film. The patient however had no evidence of peritoneal signs but only hypoactive bowel movements. Unenhanced multi-detector computed tomography (MDCT) of the abdomen and pelvis was therefore performed. MDCT revealed abnormal air-driven distension of the small and large bowel, without evidence of extra-luminal air. All radiological signs of pneumoperitoneum turned out to be false-positive results. The patient was submitted to pan-colonoscopy and to anorectal manometry to rule out Hirshprung's disease, and was finally discharged with a diagnosis of CIPO.

    The research study was carried out on 30 white Wistar rats, which were divided into three groups. In the first group the effect of carboxyperitoneum on visceral peritoneum during a two hour period at a pressure of 9-10 mm Hg and after 20 minutes its further fractional replacement during 10 seconds was examined. In the second group, the study was carried out after modeling 12-hours acute adhesive intestinal obstruction. To the third group at the beginning was given a single injection of four component mixture (carboxyperitoneum gel carboxymetiltcellulose novocaine and antibiotic) into the abdominal cavity. In the first group under the condition of tension carboxyperitoneum after a day of use there were signs of desiccations of visceral peritoneum. The increase of lipid peroxidation products and decrease of antioxidant enzymes were also observed. In the second group of animals these processes were exacerbated by acute adhesive intestinal obstruction. In the third group intraabdominal use of four component disperse mixture reduced the negative organic and functional changes in visceral peritoneum and improved its protective properties.

    Chronic intestinal pseudo-obstruction is a severe, often unrecognized disease characterized by disabling and potentially life-threatening complications over time. The diagnosis is based on the evidence of typical clinical manifestations, radiological evidence of distended bowel loops with air-fluid levels, and the exclusion of any organic obstruction of the gut lumen. The radiological sign of intestinal occlusion allows the distinction from enteric dysmotility, which is characterized by better outcomes. Manometry can play a supportive role in defining the diagnosis, and differences in the manometric pattern of chronic intestinal pseudo-obstruction and enteric dysmotility have been shown. The disease is often unrecognized, and the diagnosis, therefore, delayed by several years. Thus, the majority of patients undergo useless and potentially dangerous surgeries. Long-term outcomes are generally poor despite surgical and medical therapies characterized by disabling and potentially life-threatening complications over time. A substantial percentage of patients requires parenteral nutrition. Failure of this nutritional support represents an indication for small bowel transplantation.

    Silicone drains are often placed in the abdominal cavity for prophylactic reasons. One complication resulting from drainage includes visceral herniation at the drain site of the abdominal wall defect. An 82-year-old woman underwent a laparotomy for a large pelvic mass. After the operation, she developed small bowel incarceration, which was caused by aggressive drain extraction. Subsequent surgical treatment resulted in the patient's full recovery. This case emphasises the unusual causative mechanism of intestinal obstruction. Drains should be placed carefully in the abdominal cavity in strictly selected cases, only when it is reasonable to do so.

    2014-01-01

    Background Several types of congenital lesions can cause complete or incomplete obstruction of the intestine. Our purpose is to present 3 neonates with dual intestinal type I atresia, i.e., simultaneous obstructive lesions at 2 locations in which the atresia manifested as diaphragm-like tissue. Case presentation All 3 cases were female infants ranging in age from 2 to 14 months. The common symptom in all cases was intermittent persistent vomiting. In some cases the vomitus was bilious, and other symptoms included abdominal distention and delayed meconium passage. Prior surgeries at another hospital were unsuccessful at relieving the symptoms in one case. One case had dual lesions in the colon, one dual lesions in the duodenum, and one atresia at both the distal portion of the ileum and the descending colon. Surgical exploration and removal of the lesions at our hospital was successful in all cases, and the infants were discharged in good condition. Conclusions Type I atresia can manifest as a diaphragm-like tissue obstructing the continuity of gastrointestinal tract, and in rare cases multiple areas may be present. Base on the intermittent nature of the associated symptoms, diagnosis can be difficult and is often delayed. Physicians should be aware of this condition during the work-up of an infant with persistent intermittent vomiting. PMID:24928109

    Meckel's diverticulum (MD) is a commonly encountered congenital anomaly of the small intestine. We report an extremely unusual case of an axially torted, gangrenous MD presenting as acute intestinal obstruction. A 26-year-old male patient presented to our emergency department with 3 days history of abdominal pain, distention and bilious vomiting. On laparotomy, there was minimal hemorrhagic fluid localized in right iliac fossa and small bowel loops were dilated. A MD was seen attached to the mesentery of nonadjacent small bowel by a peritoneal band. The diverticulum was axially torted and gangrenous. In addition, there was compression of ileum by the peritoneal band resulting in intestinal obstruction, which was relieved on dividing the band. Resection and anastomosis of the small bowel including the MD was performed. We hereby report a rare and unusual complication of a MD. Although treatment outcome is generally good, pre-operative diagnosis is often difficult. PMID:24741431

    Introduction Mechanical intestinal obstruction is a disorder associated with intra-abdominal hypertension and abdominal compartment syndrome. As the large intestine intraluminal and intra-abdominal pressures are increased, so the patient’s risk for intestinal ischaemia. Previous studies have focused on hypoperfusion and bacterial translocation without considering the concomitant effect of intra-abdominal hypertension. The objective of this study was to design and evaluate a mechanical intestinal obstruction model in pigs similar to the human pathophysiology. Materials and Methods Fifteen pigs were divided into three groups: a control group (n = 5) and two groups of 5 pigs with intra-abdominal hypertension induced by mechanical intestinal obstruction. The intra-abdominal pressures of 20 mmHg were maintained for 2 and 5 hours respectively. Hemodynamic, respiratory and gastric intramucosal pH values, as well as blood tests were recorded every 30 min. Results Significant differences between the control and mechanical intestinal obstruction groups were noted. The mean arterial pressure, cardiac index, dynamic pulmonary compliance and abdominal perfusion pressure decreased. The systemic vascular resistance index, central venous pressure, pulse pressure variation, airway resistance and lactate increased within 2 hours from starting intra-abdominal hypertension (p<0.05). In addition, we observed increased values for the peak and plateau airway pressures, and low values of gastric intramucosal pH in the mechanical intestinal obstruction groups that were significant after 3 hours. Conclusion The mechanical intestinal obstruction model appears to adequately simulate the pathophysiology of intestinal obstruction that occurs in humans. Monitoring abdominal perfusion pressure, dynamic pulmonary compliance, gastric intramucosal pH and lactate values may provide insight in predicting the effects on endorgan function in patients with mechanical intestinal obstruction.

    Introduction. Femoral hernias are at high risk of strangulation due to the narrow femoral canal and femoral ring. This can lead to symptoms of obstruction or strangulation requiring emergency surgery and possible bowel resection. To our knowledge, there is only one previous published report of bilateral strangulated femoral hernia. We present our case of this phenomenon. Case Report. An 86-year-old woman presented with symptoms of small bowel obstruction. Examination revealed two tender lumps in the area of the femoral triangle. CT scan revealed bilateral femoral hernias. Both hernias were repaired and a small bowel resection on the right side was performed with side to side anastomosis. She made an uneventful recovery. Conclusion. Bilateral femoral hernias are a rare occurrence with only one reported case of bilateral strangulation. Our case highlights the importance of meticulous history taking and clinical examination as any delay in diagnosis will increase the risk of mortality and morbidity for the patient. Hernias should always be considered as a cause if one presents with symptoms of abdominal pain or obstruction. PMID:25057426

    A 32 year old woman presented with acute onset of abdominal pain and fever. An urgent computerised tomography (CT) of the whole abdomen showed dilated loop at the terminal ileum in the right lower abdomen with thickening of the wall and oedema. The CT was suggestive of distal small bowel obstruction at the ileum with surrounding wall oedema. Multiple biopsies taken from the terminal ileum and colon on colonoscopy were all unremarkable. She represented one-year later with a recurrence of intestinal obstruction. CT enteroclysis showed collapse at the distal 3 cm segment of the terminal ileum. There was no associated wall thickening, active inflammatory changes or ileitis. This was suspicious of post-inflammatory change or fibrosis. She was subsequently found to have selective IgA deficiency with recurrent infection in the terminal ileum resulting in intestinal obstruction. In conclusion, selective IgA deficiency should be considered in patients with recurrent intestinal obstruction without anatomical obstructions. PMID:28090187

    Nasoalveolar cysts, which originate from epithelial remnants of nasolacrimal duct, are nonodontogenic soft tissue lesions of the upper jaw. These cysts are thought to be developmental and are presented with fullness in the upper lip and nose, swelling on the palate, and sometimes nasal obstruction. Because of cosmetic problems, they are often diagnosed at an early stage. These lesions are mostly revealed unilaterally but also can be seen on both sides. In this case report, a patient who complained of nasal obstruction and then diagnosed with bilateral nasoalveolar cysts and treated by sublabial excision is presented and clinical features and treatment approaches are discussed with the review of literature.

    Uncertainty about the causes and natural history of salivary stones (sialoliths) and other obstructions is being dispelled by clinical and experimental research. Sialoliths are now shown to be secondary to chronic obstructive sialadenitis. Microscopic stones (sialomicroliths) accumulate during secretory inactivity in normal salivary glands and produce atrophic foci by obstruction. Microbes ascend the main salivary duct during secretory inactivity and proliferate in atrophic foci and cause spreading inflammation, leading to inflammatory swelling and fibrosis that can compress large ducts. This leads to stagnation of secretory material rich in calcium that precipitates onto degenerating cellular membranes to form a sialolith.

    Ovarian remnant syndrome (ORS) is a rare condition, in which the ovarian tissue is inadvertently left behind after difficult oophorectomy. The most common preexisting conditions associated for this complication include endometriosis, pelvic inflammatory disease, and prior abdominal surgery as in these conditions, removal of ovarian tissue becomes difficult. This is likely due to the presence of the dense fibrotic adhesions between an ovary and the surrounding structures. This residual ovarian tissue can become functional and cystic. A 56-year-old multigravida postmenopausal female was diagnosed with intestinal obstruction. She had multiple abdominal surgeries in the past, including cholecystectomy, appendectomy, hysterectomy, and bilateral salpingo-oophorectomy. Patient underwent exploratory laparotomy. Intraoperatively, extensive adhesions and scarring of bowel wall were present and approximately 15 cm proximal to the terminal ileum, a small bowel mesenteric nodule was present. Histopathology of the mesenteric nodule was consistent with the diagnosis of overian remnant. ORS can be prevented with careful resection of the entire ovarian tissue during the difficulty oophorectomy so that no ovarian tissue is left behind. PMID:28096643

    Foreign bodies in the biliary tree are rare causes of obstructive jaundice. Food bezoars are infrequent as well. They can cause biliary obstruction after biliary tract interventions, or in the presence of biliary-bowel fistula or duodenum diverticulum. Food bezoars usually pass the gastrointestinal tract without any symptoms, but they can cause abdominal pain and obstructive jaundice in the case of biliary tract obstruction. Endoscopic retrograde cholangio-pancreatography has the major role in the diagnosis and the treatment of the disease. Authors summarize the medical history of a 91-year-old female patient, who developed vomiting and right subcostal pain due to the presence of tomato peel within the ductus choledochus.

    Intestinal pseudo-obstruction (IpsO) and acute lupus pneumonitis (ALP) are uncommon severe complications of systemic lupus erythematosus (SLE). The present study reports the case of a 26-year-old female who presented with abdominal pain, nausea and vomiting as initial symptoms. Computed tomography (CT) scanning revealed the jejunal wall was thickened and streaky, mimicking the presentation of intestinal obstruction. Following emergency surgery, the patient's general condition was aggravated, with evident limb erythematous rashes. A series of laboratory examinations revealed SLE, and combined with patient's medical history IpsO was diagnosed, with a disease Activity Index score of 10. During the therapeutic period, high fever, dyspnea and oxygen saturation (SaO2) reductions were detected, and CT scans indicated lung infiltration, excluding other causes through a comprehensive infectious work-up and a bronchoalveolar lavage examination. ALP was confirmed and treated with high-dose methylprednisolone and gamma globulin supplement. The patient responded well and was discharged in 2 weeks. In the one-year tapering period and after stopping corticosteroids, the patient recovered well with no relapse detected. In conclusion, the manifestation of IpsO in SLE is rare and represents a challenge for the surgeon to establish the correct diagnosis and avoid inappropriate surgical intervention. ALP may be the consequence of emergency surgery, and immediate high-dose glucocorticoid therapy is recommended. PMID:27347044

    Chronic intestinal pseudo-obstruction results in clinical manifestations that resemble intestinal obstruction but in the absence of any physical obstructive process. Fabry disease is an X-linked lysosomal storage disease characterized by the dysfunction of multiple systems, including significant gastrointestinal involvement. We report the occurrence of chronic intestinal pseudo-obstruction in two unrelated patients with Fabry disease and the possible explanation of a direct relation of these two disorders. In Fabry disease, gastrointestinal symptoms occur in approximately 70% of male patients, but the frequency ranges from 19% to 69% in different series. In some patients, colonic dysmotility due glycolipid deposition in autonomic plexus and ganglia can lead to the pseudo-obstruction syndrome, simulating intestinal necrosis. That is why up to this date colostomy has been performed in some cases, even for children with FD without cardiac, renal or cerebrovascular compromise. Early treatment with enzyme replacement therapy in asymptomatic or mildly symptomatic patients may be justified in order to prevent disease progression. Several studies have demonstrated that enzyme replacement therapy alleviates GI manifestations. Because of the non-specific nature of the gastrointestinal symptoms, diagnosis of Fabry disease is often delayed for several years. Gastrointestinal involvement is often misdiagnosed or under-reported. It is therefore very important to consider Fabry disease in the differential diagnosis of chronic intestinal pseudo-obstruction.

    Strangulation colorectal obstruction was modeled in 60 Wistar rats. Necrotic segment of the intestine was resected under conditions of peritonitis and end-to-end intestinal anastomosis was performed on a PCV catheter conducted through the anus. Sodium hypochlorite and ozone solution were used for sanitation of the abdominal cavity and intestinal lavage, and the intestinal anastomosis was coated with Ozonide (ozonized oil). The use of physicochemical methods notably reduced the incidence of postoperative pyoinflammatory complications, incompetence of intestinal anastomosis sutures, and animal mortality.

  16. Phytobezoar in a jejunal diverticulum as a cause of small bowel obstruction: a case report

    2011-01-01

    Introduction Phytobezoars are concretions of poorly digested fruit and vegetable fibers found in the alimentary tract. Previous gastric resection, gastrojejunostomy, or pyloroplasty predispose people to bezoar formation. Small-bowel bezoars normally come from the stomach, and primary small-bowel bezoars are very rare. They are seen only in patients with underlying small-bowel diseases such as diverticula, strictures, or tumors. Primary small-bowel bezoars almost always present as intestinal obstructions, although it is a very rare cause, being responsible for less than 3% of all small-bowel obstructions in one series. Jejunal diverticula are rare, with an incidence of less than 0.5%. They are usually asymptomatic pseudodiverticula of pulsion type, and complications are reported in 10% to 30% of patients. A phytobezoar in a jejunal diverticulum is an extremely rare presentation. Case presentation A 78-year-old Pakistani man presented to our clinic with small-bowel obstruction. Upon exploration, we found a primary small-bowel bezoar originating in a jejunal diverticulum and causing jejunal obstruction. Resection and anastomosis of the jejunal segment harboring the diverticulum was performed, and our patient had an uneventful recovery. Conclusion Primary small-bowel bezoars are very rare but must be kept in mind as a possible cause of small-bowel obstruction. PMID:21951579

    The mitochondrial neurogastrointestinal encephalomyopathy syndrome (MNGIE) is a rare and life-threatening, autosomal recessive, multisystem disorder, caused by the mutations in the thymidine phosphorylase gene. Herein, we report a case of a 21 year-old male with a long history of intestinal pseudo-obstruction who was diagnosed with MNGIE syndrome after an extensive examination. In this case, our objective was to bring the gastroenterologist's attention to this difficult to diagnose syndrome in the coexistence of intestinal pseudo-obstruction and neurologic manifestations. The patient was a member of a consanguineous family of six children, in whom two sisters had died due to this disorder and one sister was affected and is still alive. The patient presented with cachexia, abdominal pain, diarrhea and muscle weakness, and was previously considered to have gluten sensitive enteropathy and treated with dietary solutions.

    In a retrospective study the authors analyzed the clinical records of 199 children ages one month to 16 years hospitalized, with the diagnosis of intestinal ascariasis, in the Instituto Nacional de Pediatria of Mexico from 1984 to 1999. The purpose of the study was to evaluate the use of anthelmintics drugs as a risk factor of intestinal obstruction by A. lumbricoides. Two groups were made for the study: Group A (n = 66) of children who presented intestinal obstruction, Group B (n = 133) children with no complications. A comparative analysis of clinical data of both groups was made by means of chi square with Yates correction and a stratified analysis by means of chi square. Possible confusing elements were overcrowding, age and the use of antiparasitic drugs. The calculus of risk factors for intestinal obstruction by A. lumbricoides was done by means of contingency tables of 2 x 2 and odds ratio with an IC of 95%. The significant risk factors were included in a model of logistics regression with an impact variable consting in the presence or absence of intestinal obstruction in order to establish a multivariate model of predictive risk at level of significance of p < 0.05. Twenty-seven patients (40.90%) in group A (n = 66) were given anthelmintics medications prior to the intestinal obstruction: mebendazol, 14 (51-85%); two, albedazol (7.4%); eight, a non-specified anthelmintic (29.6%). In addition, an anthelmintic medication without a specified time of ingestion: two with mebendazol and one with piperazine (11.3%). In the case of mebendazol, the drug most frequently associated with intestinal obstruction, seven patients received it on the same day of the obstruction; five patients received it between one and seven days prior to the obstruction; two received it seven days prior to the complication. In the control group, only 7% had taken the anthelmintic one to seven days before the diagnosis of uncomplicated intestinal ascariasis diagnosis was made. With the step

    Chronic intestinal pseudo-obstruction (CIPO) is a heterogeneous group of rare disorders characterised by symptoms of intestinal obstruction with no mechanical evidence of obstruction. It is caused by ineffective intestinal contractions due to visceral neuropathy and/or neuropathy. In adults, CIPO is mostly secondary. The most common causes are metabolic disorders, connective tissue disorders, neuropathic drug related injuries, paraneoplasic and post-infectious syndromes and amyloidosis. Secondary forms of CIPO have been reported with anti-Hu antibodies. This corresponds to an antineuronal antibody that recognizes a protein expressed in the nuclei of neuron (ANNA-1) and neoplasic cells. The anti-Hu antibody must be searched for in patients over 40 years old with CIPO (associated with small cell lung cancer in 75% of cases). Recently, the association of CIPO and the anti-Hu antibody has been described without associated neoplasia. We report a case of an association of CIPO and anti-Hu antibody without cancer after 13 years of follow-up.

    CIPO is the very “tip of the iceberg” of functional gastrointestinal disorders, being a rare and frequently misdiagnosed condition characterized by an overall poor outcome. Diagnosis should be based on clinical features, natural history and radiologic findings. There is no cure for CIPO and management strategies include a wide array of nutritional, pharmacologic, and surgical options which are directed to minimize malnutrition, promote gut motility and reduce complications of stasis (ie, bacterial overgrowth). Pain may become so severe to necessitate major analgesic drugs. Underlying causes of secondary CIPO should be thoroughly investigated and, if detected, treated accordingly. Surgery should be indicated only in a highly selected, well characterized subset of patients, while isolated intestinal or multivisceral transplantation is a rescue therapy only in those patients with intestinal failure unsuitable for or unable to continue with TPN/HPN. Future perspectives in CIPO will be directed toward an accurate genomic/proteomic phenotying of these rare, challenging patients. Unveiling causative mechanisms of neuro-ICC-muscular abnormalities will pave the way for targeted therapeutic options for patients with CIPO.

    Sclerosing mesenteritis falls within a spectrum of primary idiopathic inflammatory and fibrotic processes that affect the mesentery. The exact etiology has not been determined, although the following associations have been noted: abdominal surgery, trauma, autoimmunity, paraneoplastic syndrome, ischemia and infection. Progression of sclerosing mesentritis can lead to bowel obstruction, a rare complication of this uncommon condition. We report a case of a 66-year-old female with abdominal pain who was noted to have a small bowel obstruction requiring laparotomy and a partial small bowel resection. The pathology of the resected tissue was consistent with sclerosing mesenteritis, a rare cause of a small bowel obstruction. Sclerosing mesenteritis has variable rates of progression, and there is no consensus regarding the optimal treatment. Physicians should consider sclerosing mesenteritis in the differential diagnosis of a small bowel obstruction.

    AIM: To observe the protective effect of glucagon-like peptide-2 (GLP-2) on the intestinal barrier of rats with obstructive jaundice and determine the possible mechanisms of action involved in the protective effect. METHODS: Thirty-six Sprague-Dawley rats were randomly divided into a sham operation group, an obstructive jaundice group, and a GLP-2 group; each group consisted of 12 rats. The GLP-2 group was treated with GLP-2 after the day of surgery, whereas the other two groups were treated with the same concentration of normal saline. Alanine aminotransferase (ALT), total bilirubin, and endotoxin levels were recorded at 1, 3, 7, 10 and 14 d. Furthermore, on the 14th day, body weight, the wet weight of the small intestine, pathological changes of the small intestine and the immunoglobulin A (IgA) expressed by plasma cells located in the small intestinal lamina propria were recorded for each group. RESULTS: In the rat model, jaundice was obvious, and the rats’ activity decreased 4-6 d post bile duct ligation. Compared with the sham operation group, the obstructive jaundice group displayed increased yellow staining of abdominal visceral serosa, decreased small intestine wet weight, thinning of the intestinal muscle layer and villi, villous atrophy, uneven height, fusion, partial villous epithelial cell shedding, substantial inflammatory cell infiltration and significantly reduced IgA expression. However, no significant gross changes were noted between the GLP-2 and sham groups. With time, the levels of ALT, endotoxin and bilirubin in the GLP-2 group were significantly increased compared with the sham group (P < 0.01). The increasing levels of the aforementioned markers were more significant in the obstructive jaundice group than in the GLP-2 group (P < 0.01). CONCLUSION: GLP-2 reduces intestinal mucosal injuries in obstructive jaundice rats, which might be attributed to increased intestinal IgA and reduced bilirubin and endotoxin. PMID:25593463

    PubMed

    Buttó, Ludovica F; Haller, Dirk

    2016-08-01

    The intestinal microbiota encompasses hundreds of bacterial species that constitute a relatively stable ecosystem. Alteration in the microbiota composition may arise from infections, immune defects, metabolic alterations, diet or antibiotic treatment. Dysbiosis is considered as an alteration in microbiota community structure and/or function, capable of causing/driving a detrimental distortion of microbe-host homeostasis. A variety of pathologies are associated with changes in the community structure and function of the gut microbiota, suggesting a link between dysbiosis and disease etiology. With an emphasis in this review on inflammatory bowel diseases (IBD), the non-trivial question is whether dysbiosis is the cause or consequence of inflammation. It is important to understand whether changes in microbial ecosystems are causally linked to the pathology and to what extend disease risk is predicable based on characteristic changes in community structure and/or function. Local changes in tissue integrity associated with focal areas of inflammation may result in the selection of a dysbiotic bacterial community associated with the propagation of a disease phenotype. This review outlines the role of dysbiosis in intestinal inflammation with particular focus on IBD-relevant gnotobiotic mouse models, the factors implicated in the development of dysbiosis and the means available to investigate dysbiosis in the context of human diseases.

    2015-01-01

    Introduction Bezoar is an unusual cause of small bowel obstruction accounting for 0.4–4% of all mechanical bowel obstruction. The common site of obstruction is terminal ileum. Case report A 28-year-old male with no past surgical history, known to have severe mental retardation presented with anorexia. CT scan demonstrated dilated small bowel loops and intraluminal ileal mass with mottled appearance. At exploratory laparotomy, a bezoar was found impacted in the terminal ileum 5–6 inches away from the ileocecal valve and was removed through an enterotomy. Discussion Bezoars are concretions of fibers or foreign bodies in the alimentary tract. Small bowel obstruction is one of common clinical symptoms. The typical finding of well-defined intraluminal mass with mottled gas pattern in CT scan is suggestive of an intestinal bezoar. The treatment option of bezoar is surgery including manual fragmentation of bezoar and pushing it toward cecum, enterotomy or segmental bowel resection. Thorough exploration of abdominal cavity should be done to exclude the presence of concomitant bezoars. Recurrence is common unless underlying predisposing condition is corrected. Conclusions Bezoar-induced small bowel obstruction remains an uncommon diagnosis. It should be suspected in patients with an increased risk of bezoar formation, such as in the presence of previous gastric surgery, a history suggestive of increased fiber intake, or patient with psychiatric disorders. CT scan is helpful for preoperative diagnosis. PMID:26764889

    Background/Aims Chronic intestinal pseudo-obstruction (CIPO) is a rare syndrome characterized by a failure of the propulsion of intraluminal contents and recurrent symptoms of partial bowel obstruction in the absence of mechanical obstruction. Regional variations of the intestinal compromise have been described. Intestinal manometry can indicate the pathophysiology and prognosis. Our objective is to establish the demographic and clinical characteristics of group Chilean patients and analyze the motility of the small intestine and its prognostic value. Methods Patients with symptoms of intestinal pseudo-obstruction with dilated bowel loops were included, in all of whom a manometry of the small intestine was performed using perfused catheters. Results Of the 64 patients included, 51 women (average age 41.5 ± 17.6 years), 54 primary and 10 secondary CIPO were included. Dilatation of the small intestine was the only finding in 38 patients; in the remaining, the compromise was associated with other segments, primarily the colon. Forty-nine patients underwent 65 surgeries, mainly exploratory laparotomies and colectomies. Intestinal manometry was performed on all patients; 4 “patterns” were observed: neuropathic (n = 26), myopathic (n = 3), mixed (n = 24), and a group without motor activity (n = 11). The most relevant findings were the complex migrating motor disorders and decreased frequency and propagation of contractions. The 9 patients who died had a severe myopathic compromise. Conclusions In our series, isolated small bowel compromise was the most common disorder. Neuropathic motor compromise was observed in most of the patients. Mortality was associated with severe myopathic compromise. PMID:27669829

    Intestinal pseudo-obstruction is a clinical syndrome in which the clinical symptoms of intestinal obstruction appear without mechanical obstruction of the intestine. We searched for articles from Japana Centra Revuo Medicina for the period 1983-2009 using the keywords 'chronic' and 'intestinal pseudo-obstruction'. 124 articles were identified, and of these 121 cases were investigated using our diagnostic criteria. The patients were between 0 (just after birth) and 84 years of age, indicating that chronic intestinal pseudo-obstruction (CIP) can occur at any age. The mean age was 43.6 years and the median age was 47 years. Forty-nine patients were male and 72 were female, showing a slight tendency towards female predominance. Five cases (4.2%) had a definitive family history. Of the identified causes of secondary CIP, systemic sclerosis was the most common. Abdominal bloating was the most common initial symptom, seen in 90 (81%) patients. Patients having poor intestinal peristalsis with stagnation of the contents of the small intestines causing fatty stools and bacterial overgrowth complained of diarrhea. The interval between the initial symptoms and diagnosis ranged from 0 to 60 years, with a mean and median interval of 7.3 and 2 years, respectively. In case reports of CIP in Japan, the sensitivity of our diagnostic criteria was found to be 85.9%, indicating that the criteria are useful. For improvement in the rate of recognition of CIP and practical application of the diagnostic criteria in Japan, it is important to conduct further studies.

    Ventriculoperitoneal (VP) shunt complications are common, but abdominal complications are rare. The objective of this report is to present 2 cases of intestinal obstruction due to a VP shunt and review the literature for data on this rare occurrence.A 4-month-old boy received surgical resection of a medulloblastoma and a VP shunt was inserted to manage progressive hydrocephalus. Two months later, he was admitted with intermittent vomiting, and plain abdominal radiography showed complete intestinal obstruction. Emergency laparotomy revealed an adhesive intestinal obstruction around the catheter, and approximately 5 cm of necrotic ileum was resected. His recovery was uneventful. In the second case, a 6-year-old boy was diagnosed with a primary nongerminomatous malignant germ cell tumor and a VP shunt was place to treat hydrocephalus. Two weeks after the first course of chemotherapy, he went into a coma; computed tomography demonstrated enlargement of the tumor and gross total resection was performed. Two weeks later, he developed abdominal distention; plain radiography showed intestinal obstruction and laparotomy revealed adhesive intestinal obstruction around the catheter with 15 cm of necrotic ileum. The necrotic bowel was resected. Unfortunately, the patient developed sepsis and despite treatment remained in a vegetative state.Medline, Central, Embase, and Google Scholar databases were searched up to May 9, 2014, using the terms VP shunt, shunting, and/or intestinal obstruction. Only cases involving children or adolescents were included. Eleven reports involving patients with abdominal complications resulting from a VP shunt for hydrocephalus were identified. The dates of the reports spanned from 1971 to 2014. Volvulus was the most common cause of VP shunt-related obstruction, and mechanical obstruction due to twisting of the catheter the second most common. Only 1 case in the literature review was related to intestinal adhesions. Treatment in most cases was

    Gastrointestinal symptoms, such as abdominal pain and diarrhea, are frequently observed in patients with Plasmodium falciparum malaria. However, the correlation between malaria intestinal pathology and intestinal microbiota has not been investigated. In the present study, infection of C57BL/6 mice with P. berghei ANKA (PbA) caused intestinal pathological changes, such as detachment of epithelia in the small intestines and increased intestinal permeability, which correlated with development with experimental cerebral malaria (ECM). Notably, an apparent dysbiosis occurred, characterized by a reduction of Firmicutes and an increase in Proteobacteria. Furthermore, some genera of microbiota correlated with parasite growth and/or ECM development. By contrast, BALB/c mice are resistant to ECM and exhibit milder intestinal pathology and dysbiosis. These results indicate that the severity of cerebral and intestinal pathology coincides with the degree of alteration in microbiota. This is the first report demonstrating that malaria affects intestinal microbiota and causes dysbiosis.

    The histopathological approach of chronic intestinal pseudo-obstruction (CIP) is critical, and the findings are often missed by the histopathologists for lack of awareness and nonavailability of standard criteria. We aimed to describe a detailed histopathological approach for working-up cases of CIP by citing our experience. Eight suspected cases of CIP were included in the study to determine and describe an approach for reaching the histopathological diagnosis collected over a period of the last 1.5 years. The Hirschsprung's disease was put apart from the scope of this study. A detailed light microscopic analysis was performed along with special and immunohistochemical stains. Transmission electron microscopy was carried out on tissue retrieved from paraffin embedded tissue blocks. Among the eight cases, three were neonates, one in the pediatric age group, two adolescent, and two adults. After following the described critical approach, we achieved the histological diagnoses in all the cases. The causes of CIP noted were primary intestinal neuronal dysplasia (IND) type B (in 4), mesenchymopathy (in 2), lymphocytic myenteric ganglionitis (in 1), and duplication of myenteric plexus with leiomyopathy (in 1). Desmosis was noted in all of them along with other primary pathologies. One of the IND patients also had visceral myopathy, type IV. Histopathologists need to follow a systematic approach comprising of diligent histological examination and use of immunohistochemistry, immunocytochemistry, and electron microscopy in CIP workup. Therapy and prognosis vary depending on lesions identified by pathologists. These lesions can be seen in isolation or in combinations.

    Ellis-van Creveld (EVC) syndrome is a rare autosomal recessive disorder characterized by hypoplastic nails, polydactyly, and achondroplasia. Patients usually exhibit normal cognitive function and no remarkable developmental delay. We herein present an unusual case of EVC syndrome. A Japanese 2-year-old boy was born at term, but immediately developed severe respiratory failure due to thorax deformity, postaxial polydactyly and nail hypoplasia. We identified a novel pattern of germinal compound heterozygous nonsense EVC2 mutations of c.1814C > A (p. S605X) and c.2653C > T (p. R885X), leading to the diagnosis of EVC syndrome. Interestingly, he also had severe developmental delay, and suddenly developed excessive abdominal distension at the age of 2. On surgery, extensive necrotic bowel with chronic intestinal pseudo-obstruction was noted. This is, to our knowledge, a most severe phenotype of EVC syndrome, illustrating that the specific pattern of EVC2 compound heterozygous mutations may cause severe developmental delay and intestinal malfunction.

    Presented are the results of experimental research on 144 animals (the rats Wistar), on whom was carried out resection of a part of large intestine and a intestinal anastamosis was formed in the presents of acute intestinal obstruction and peritonitis. The sanitation of abdominal cavity in the basic group of animals (74) was performed using sodium hypochlorite solution and dissolved ozone. The intestinal lavage was carried out by dissolved ozone with the subsequent introduction of ozonized oil Ozonide in the area of intestinal anastamosis. The combined application of ozone and sodium produces an expressed samative effect which leads to healing of intestinal anastamosis and decreases unstability of intestinal sutures and mortality.

    Chronic intestinal pseudo-obstruction (CIPO) is a rare clinical syndrome of ineffective intestinal motility characterised by clinical and radiological evidence of intestinal obstruction with no identifiable mechanical lesion. CIPO can either be idiopathic or secondary to a systemic disease, like systemic lupus erythematosus (SLE). Fewer than 30 cases of CIPO secondary to SLE have been reported so far. Here we describe a case of SLE with the initial presentation of CIPO. In SLE-related CIPO, treatment includes a combination of high-dose intravenous corticosteroids, immunosuppressants and supportive care. With awareness of this condition, unnecessary surgical intervention and repeated invasive procedures could be avoided. Early initiation of treatment would avoid complications and bring about resolution of symptoms.

    We present three cases of self-expandable metallic stent (SEMS) placement using a balloon enteroscope (BE) and its overtube (OT) for malignant obstruction of surgically reconstructed intestine. A BE is effective for the insertion of an endoscope into the deep bowel. However, SEMS placement is impossible through the working channel, because the working channel of BE is too small and too long for the stent device. Therefore, we used a technique in which the BE is inserted as far as the stenotic area; thereafter, the BE is removed, leaving only the OT, and then the stent is placed by inserting the stent device through the OT. In the present three cases, a modification of this technique resulted in the successful placement of the SEMS for obstruction of surgically reconstructed intestine, and the procedures were performed without serious complications. We consider that the present procedure is extremely effective as a palliative treatment for distal bowel stenosis, such as in the surgically reconstructed intestine.

We experienced a case of chronic pseudo-obstruction in the initial phase mimicking acute pseudo-obstruction, which was treated medically. This ongoing case was compared to another recurrent and intractable case successfully treated with surgery and diagnosed as hypoganglionosis. These two cases showed different clinical features and therapeutic approaches for CIPO; one with the first episode of CIPO mimicking Ogilvie's syndrome; the other with recurrent episodes of CIPO with typical features. In conclusion, CIPO is a difficult disorder with various clinical manifestations and different treatment modalities, therefore individualized diagnostic and therapeutic approaches are needed.

    Chronic intestinal pseudo-obstruction (CIPO) is a rare intestinal motility disorder with significant morbidity and mortality in pediatric patients. The diagnosis of CIPO is difficult, because it is clinically based on the symptoms and signs of bowel obstruction which are similar to the clinical manifestations of other gastrointestinal diseases like short bowel syndrome (SBS). Therefore, it is desirable to identify and establish new laboratory diagnostic markers for CIPO that are reliable and easily accessible. In our study we have identified the ratio of the urinary glutamine and glutamic acid as a promising biomarker for distinguishing suspected CIPO cases and simple SBS cases. The area under ROC curve was 0.83, at cutoff value = 7.04 with sensitivity of 65% and specificity of 92%.

    Ventriculoperitoneal (VP) shunt placement is the mainstay of treatment for hydrocephalus, yet shunts remain vulnerable to a variety of complications. Although fat droplet migration into the subarachnoid space and cerebrospinal fluid pathways following craniotomy has been observed, a VP shunt obstruction with fat droplets has never been reported to our knowledge. We present the first reported case of VP shunt catheter obstruction by migratory fat droplets in a 55-year-old woman who underwent suboccipital craniotomy for removal of a metastatic tumor of the left medullocerebellar region, without fat harvesting. A VP shunt was inserted 1month later due to communicating hydrocephalus. The patient presented with gait disturbance, intermittent confusion, and pseudomeningocele 21days after shunt insertion. MRI revealed retrograde fat deposition in the ventricular system and VP shunt catheter, apparently following migration of fat droplets from the fatty soft tissue of the craniotomy site. Spinal tap revealed signs of aseptic meningitis. Steroid treatment for aseptic "lipoid" meningitis provided symptom relief. MRI 2months later revealed partial fat resorption and resolution of the pseudomeningocele. VP shunt malfunction caused by fat obstruction of the ventricular catheter should be acknowledged as a possible complication in VP shunts after craniotomy, even in the absence of fat harvesting.

    Intestinal pseudo-obstruction (IPO) is a rare but dangerous complication of systemic lupus erythematosus (SLE) when the patient has no other manifestations except gastrointestinal symptoms. We performed 1 patient with a 2-month history of recurrent vomiting and abdominal distension. She admitted past surgical histories of cesarean section and appendectomy. A physical examination revealed tenderness in the right lower abdominal on palpation and bowel sounds were weak, 2 to 3 bpm. An x-ray and CT of her abdomen showed intestinal obstruction. The initial diagnosis was adhesive intestinal obstruction. She received surgical treatment because her symptoms had gradually become more frequent and persistent. But she vomited again 2 weeks later after the surgery. Further immunology tests indicated that she had an IPO secondary to SLE. We treated the patient with methylprednisolone pulse for 3 days and followed by prednisone orally. The patient had a good response. Complete remission was achieved on 8 years follow-up. The importance of IPO secondary to SLE lies in an early diagnosis. After the diagnosis is established, immunosuppressive therapy should be the initial and first-line treatment, and surgical intervention is often disappointing and should be carefully avoided. It is necessary to enhance awareness of doctors to IPO secondary to SLE.

    Chronic intestinal pseudo-obstruction (CIPO) syndromes are heterogeneous gastrointestinal disorders, caused by either neuropathy or myopathy, resulting in compromised peristalsis and intestinal obstruction. CIPO can have a profound impact on quality of life, leading the most severely affected individuals to life-long parenteral nutrition and urinary catheterization. To search for disease causing gene(s), we performed the whole exome sequencing (WES) in both eight sporadic and two familial cases, followed by targeted sequencing in additional CIPO patients. After identifying a heterozygous missense variant in the ACTG2 gene in one of 10 patients undergone WES, targeted Sanger sequencing of this gene allowed to detect heterozygous missense variants in 9 of 23 further patients with either megacystis-microcolon-intestinal hypoperistalsis syndrome or intestinal pseudo-obstruction. Variants thus identified, one of which still unreported, affect highly conserved regions of the ACTG2 gene that encodes a protein crucial for correct enteric muscle contraction. These findings provided evidence for a correlation between the clinical phenotype and genotype at the ACTG2 locus, a first step to improve the diagnosis and prognosis of these severe conditions.

    Intestinal neuronal dysplasia type B (IND-B) is a controversial entity among the gastrointestinal neuromuscular disorders. It may occur alone or associated with other neuropathies, such as Hirschsprung’s disease (HD). Chronic constipation is the most common clinical manifestation of patients. IND-B primarily affects young children and mimics HD, but has its own histopathologic features characterized mainly by hyperplasia of the submucosal nerve plexus. Thus, IND-B should be included in the differential diagnoses of organic causes of constipation. In recent years, an increasing number of cases of IND-B in adults have also been described, some presenting severe constipation since childhood and others with the onset of symptoms at adulthood. Despite the intense scientific research in the last decades, there are still knowledge gaps regarding definition, pathogenesis, diagnostic criteria and therapeutic possibilities for IND-B. However, in medical practice, we continue to encounter patients with severe constipation or intestinal obstruction who undergo to diagnostic investigation for HD and their rectal biopsies present hyperganglionosis in the submucosal nerve plexus and other features, consistent with the diagnosis of IND-B. This review critically discusses aspects related to the disease definitions, pathophysiology and genetics, epidemiology distribution, clinical presentation, diagnostic criteria and therapeutic possibilities of this still little-known organic cause of intestinal chronic constipation.

    Gastric outlet obstruction (GOO) presenting beyond the newborn period is a relatively rare condition, when infantile hypertrophic pyloric stenosis (IHPS) is excluded. This report describes the clinical features, evaluation and management of 18 patients with GOO which was not caused by IHPS. The sex, age, and main presenting features were recorded on admission. Hemoglobin estimation, serum chemistry and blood gas analysis were also assessed in these patients. The diagnosis was confirmed with gastrointestinal barium, B ultrasound, gastroscopy, or at surgery. Some of them underwent gastroscopy with biopsy sampling for rapid urease test or histologic examination with Giemsa stains for Helicobacter pylori. Thirteen patients had peptic ulcer disease, of which six were successfully treated with medications. While the other seven needed operative management which included Heineke-Mikulicz pyloroplasty, gastroduodenostomy or gastrojejunostomy, respectively. All the patients who had Heineke-Mikulicz pyloroplasty or gastrojejunostomy developed bile reflux gastritis that could be alleviated with omeprazol. None of the patients developed dumping syndrome, failing to thrive, or anemia. Three children with antral diaphragm recovered without any complications by diaphragm excision with Heineke-Mikulicz pyloroplasty. The pylorus was compressed by fibrotic band in one 30-month boy, and he recovered uneventfully with Heineke-Mikulicz pyloroplasty during 10-year follow-up. Gastric outlet obstruction secondary to ingestion of sulfuric acid was noted in one patient, and he was successfully treated with gastroduodenostomy. Our data suggests that the satisfactory results could be expected in children with GOO with different therapeutic modalities based on the specific cause and degree of obstruction.

    A 37-year-old woman who had previously been diagnosed with idiopathic chronic intestinal pseudo-obstruction (CIPO) at another hospital was admitted to our institution with severe abdominal pain. She had a history of several abdominal surgeries to treat ileus at the previous hospital, and contrast-enhanced computed tomography on admission revealed subileus without any apparent causes of obstruction. Total parenteral nutrition, a gastrointestinal prokinetic agent, and opiates reduced persistent pain;however, breakthrough pain continued. A neurologist at our hospital suggested autoimmune autonomic ganglionopathy (AAG) as a potential cause of CIPO. The patient was diagnosed with suspected AAG on the basis of seropositive results for anti-ganglionic acetylcholine receptor antibody. Intravenous immunoglobulin administration and plasma exchange were performed in combination with immunosuppressive drugs;however, her symptoms barely improved. Although percutaneous endoscopic gastrostomy and enterostomy were subsequently performed to reduce internal intestinal pressure, her pain relief was insufficient.

    Duodenal phytobezoar, an unusual cause of acute duodenal obstruction, is rarely seen. The most common cause of this type of bezoar is persimmon. It frequently arises from underlying gastrointestinal tract pathologies (gastric surgery, etc.). Here, we report the case of a 66-year-old man who had undergone distal gastrectomy with Billroth I reconstruction for gastric cancer and experienced severe epigastric discomfort, abdominal pain, and vomiting for a few days. The abdominal computed tomography scan showed a large-sized mass in the horizontal portion of the duodenum. On following endoscopic examination, a large phytobezoar was revealed in the duodenum. He was treated with endoscopic fragmentation combined with nasogastric Coca-Cola. The patient tolerated the procedure well and resumed a normal oral diet 3 days later.

    An adult Bengal cat (Felis catus × Prionailurus bengalensis) with a prolonged history of partial anorexia, regurgitation, and weight loss and a clinical, radiographic, and ultrasonographic diagnosis of persistent megaesophagus and gastrointestinal ileus was submitted for necropsy. The intestinal tract was diffusely distended by gas and fluid with appreciable loss of muscle tone and an absence of luminal obstruction, consistent with the clinical history of chronic intestinal pseudo-obstruction. Histologically, the autonomic nervous system was intact, but the smooth muscle within the gastrointestinal wall exhibited a marked basophilia that was most pronounced in the jejunum. Immunohistochemistry for neurofilament, synaptophysin, CD117, and desmin demonstrated that the number of myenteric ganglia, number of interstitial cells, and leiomyocyte desmin content were similar when compared with the unaffected age- and species-matched control. Immunohistochemistry for smooth muscle α-actin demonstrated a striking loss of immunoreactivity, predominantly in the circular layer of the jejunum, that corresponded with the tinctorial change in leiomyocytes. Transmission electron microscopy revealed loss of myofibrils, loss of organelle polarity, and significantly larger central mitochondria (megamitochondria) in affected leiomyocytes, as well as nonspecific degenerative changes. Although the presence of a primary leiomyopathy and a causal relationship could not be confirmed in this case, leiomyopathies are considered a cause of chronic intestinal pseudo-obstruction in human medicine, and loss of smooth muscle α-actin immunoreactivity is one recognized marker for intestinal dysmotility.

    Right sided congenital diaphragmatic hernia may cause biliary obstruction. We present a 2 months female infant who had respiratory distress and persistent jaundice since birth. Investigations suggested direct hyperbilirubinemia, right-sided diaphragmatic hernia with liver herniation in the thorax, and intra- and extrahepatic biliary dilatation. Laparotomy showed herniation of liver in the chest with hepatic torsion of about 180° causing obstruction of bile ducts. Liver torsion was corrected and liver relocated in the abdomen. An operative cholangiogram confirmed free passage of contrast to the intestine after correction of hepatic torsion. Repair of the diaphragmatic hernia was performed. Only skin closure was performed leaving a ventral hernia to avoid abdominal compartment syndrome. Postoperatively, the baby was kept on ventilator for 2 days and then extubated. She showed rapid recovery and was discharged in a stable condition. The ventral hernia was repaired at the age of 6 months. Her total bilirubin levels dropped gradually from 12.50 mg/dl into its normal values within 3 months. PMID:28082781

    Chronic intestinal pseudo obstruction (CIPO) is a rare clinical entity characterized by symptoms and signs of intestinal obstruction without either recognizable anatomical abnormalities or intestinal aganglionosis. A Chinese female infant presented to our institution with a clinical diagnosis of CIPO. Aganglionosis was ruled out by full thickness colonic and ileal biopsies and by rectal suction biopsies. Unexpectedly, direct sequencing and PCR amplification of RET proto-oncogene from peripheral blood extracted DNA identified a RET R114H mutation. This mutation has already been reported as strongly associated with Asian patients affected by Hirschsprung's disease (HSCR) and is considered a founder mutation in Asia. The same mutation has never been reported in patients with CIPO, so far. These findings support the role of RET in the development of the enteric nervous system but underline the importance of other genetic or environmental factors contributing to the gastrointestinal phenotype of the disease. Somehow, this RET R114H mutation proved to have a role in the etiology of both CIPO and HSCR and could contribute to a more diffuse imbalance of gut dysmotility. © 2016 Wiley Periodicals, Inc.

    A 26-year-old patient was diagnosed as having chronic intestinal pseudo-obstruction with manometric and histopathologic features suggestive of an intestinal myopathy. Histology was characterized by smooth muscle degeneration without inflammatory or immune cells. The severe gut dysfunction required full parenteral nutritional support. After a few months, the patient developed symptomatic tachy-brady arrhythmia episodes with syncopes. A thorough diagnostic work-up led to a diagnosis of sick sinus syndrome, which was managed by pacemaker implantation and administration of β-blockers. This led to a partial improvement in tachy-brady arrhythmia episodes. Nonetheless, the patient continued to experience sustained supraventricular tachyarrhythmia runs, poorly responsive to increasing β-blocker doses. To investigate the origin of the cardiologic impairment, the patient was tested for anticonductive tissue autoantibodies, which were positive, thus supporting a possible autoimmune origin of the dysrhythmia. Other autoantibodies were negative. On the basis of these findings, the patient was treated with high-dose steroids, which were then tapered. The patient responded to the steroid treatment and did not experience further episodes of syncope and tachyarrhythmias. The severe gut dysfunction remained unchanged. This case highlights an association between severe gut dysfunction and cardiac conductive tissue abnormalities, with autoantibodies to conductive tissue possibly causing the dysrhythmia. The severe gut and heart (likely autoimmune-mediated) dysfunction presented in this case provides a basis to further assess a link between intestinal and cardiac abnormal rhythmicity.

    Ampullary adenomas are a rare clinical entity, occurring at a rate of 0.04–0.12% in the general population. They are premalignant lesions which have the capability to progress to malignancy, and they should be excised if they are causing immediate symptoms and/or are likely to degenerate to carcinoma. Intestinal intussusception in adults is rare and, unlike in children, is often due to a structural pathology. Intussuscepting duodenal/ampullary adenomas have been reported in the literature on 13 previous occasions, however never before with this presentation. We report the case of a woman who presented with a 1-year history of recurrent chest infections. She was treated with numerous antibiotics, whilst intermittent symptoms of recurrent vomiting and weight loss were initially attributed to her lung infections. A chest CT demonstrated multiple cavitating lung lesions, whilst an obstructing polypoid mass was noted at D2 on dedicated abdominal imaging. Due to ongoing nutritional problems, she had a semi-urgent pancreaticoduodenectomy. Intraoperative findings demonstrated a large mass at D2 with a duodeno-duodenal intussusception. Histological analysis reported a duodenal, ampullary, low-grade tubular adenoma, 75 × 28 × 30 mm in size, with intussusception and complete resection margins. The patient recovered well and was discharged on postoperative day 10, with no complications to date. Ampullary adenomas may present with obstruction of the main gastrointestinal tract and/or biliary/pancreatic ducts. Common presentations include gastric outlet obstruction, gastrointestinal bleeding or acute pancreatitis. This unique presentation should remind clinicians of the need to investigate recurrent chest infections for a possible gastrointestinal cause. PMID:27920640

    Cisapride is a gastrointestinal prokinetic that facilitates or restores motility along the entire gastrointestinal tract. It has been used successfully to treat acute and chronic intestinal pseudo-obstructions (CIPs) in adults, but there is a paucity of literature surrounding the treatment of CIP in pediatric patients and therapies for CIP are limited and their impact is often unsatisfactory. This case report presents the use of cisapride in the management of pseudo-obstruction. Treatment with cisapride substantially improved the patient's symptoms and improved feeding tolerance. It improved his prognosis remarkably and prevented the need for end-of-life care. He experienced no adverse effects throughout the course of therapy. The treatment regimen is discussed in this case report.

    The gut microbiota is intimately involved in numerous aspects of normal human physiology, including nutrition and metabolism, immunomodulation and behavior and stress response. Intestinal dysbiosis can be a contributing cause of many diseases, altering the function of both near and far organ systems. During pregnancy, the maternal body undergoes dramatic physiological changes to support the growth of fetus-placenta, while intestinal dysbiosis may directly or indirectly disturb the remodeling of physiological balance, leading to maternal maladaptation. Thus, intestinal dysbiosis, i.e., altered composition or metabolism of microbiota may adversely affect pregnancy outcome and lead to pregnancy complications via disrupting maternal adaptation. Indeed, pregnant women with potential maladaptations are at high risk of developing pregnancy disorders, which is increasingly observed in clinical cases. Here we discuss the hypothesis that intestinal dysbiosis may induce pregnancy complications via affecting maternal adaptation and the possible mechanistic pathways.

    Intestine and intestine-liver transplant plays an important role in the treatment of intestinal failure, despite decreased morbidity associated with parenteral nutrition. In 2014, 210 new patients were added to the intestine transplant waiting list. Among prevalent patients on the list at the end of 2014, 65% were waiting for an intestine transplant and 35% were waiting for an intestine-liver transplant. The pretransplant mortality rate decreased dramatically over time for all age groups. Pretransplant mortality was highest for adult candidates, at 22.1 per 100 waitlist years compared with less than 3 per 100 waitlist years for pediatric candidates, and notably higher for candidates for intestine-liver transplant than for candidates for intestine transplant without a liver. Numbers of intestine transplants without a liver increased from a low of 51 in 2013 to 67 in 2014. Intestine-liver transplants increased from a low of 44 in 2012 to 72 in 2014. Short-gut syndrome (congenital and other) was the main cause of disease leading to both intestine and intestine-liver transplant. Graft survival improved over the past decade. Patient survival was lowest for adult intestine-liver recipients and highest for pediatric intestine recipients.

    Uncertain etiology of cervical osteophytes, in particular emerging in geriatric population, is a rare skeletal system disease. Often, the cases are asymptomatic and may lead to symptoms such as dysphagia, cough, dyspnea, and dysphonia. We present a patient who had anterior osteophytes causing symptoms of severe obstructive sleep apnea (OSA), and literature on etiology of OSA has been reviewed. A 57-year-old male patient with complaints of snoring and cessation of breathing during sleep was referred to the ear nose throat clinic. Cervical radiograph and computed tomography showed the osteophytes in the anterior of the vertebral corpus at the level C1-2. In addition, bridging osteophyte was observed between C6 and C7 vertebrae. The patient's neck circumference was 41 cm, body mass index was 29 kg/m2, Epworth Sleepiness Scale score was 11, and apnea hypopnea index was 62. Surgery was recommended, but the patient refused. Continuous positive airway pressure titration was applied with 12.6 cm H2O pressure; apnea control was attained with an AHI of 2.7. One of the rare causes of OSA, a case of cervical vertebral osteophyte, was presented, and we would like to draw attention to the importance of ear nose throat examination in the diagnosis of OSA.

    A 64-year-old woman was hospitalized at an internal care unit, due to growing weakness, dizziness, lack of appetite, anemia and abdominal pain. In anamnesis: past myocardial infarction, post-operative hypothyroidism, type 2 diabetes insulin-dependent, stroke, left kidney cirrhosis, gout and anemia. The physical examination did not reveal pathological changes except for skin paleness. The biochemical tests showed iron deficiency anemia and elevated Ca 125 (54.5 U/ml) (normal range: 0.00–35.00). Other markers were normal. An abdominal CT revealed a bifocal infiltration of the small intestine. Due to the increasing obstruction symptoms, the patient was operated on. A bifocal small bowel tumor was found intra-surgically. A partial resection of the jejunum and distal ileum was made. The intestines were joined end to end. The histopathological diagnosis corresponded to metastases of malignant melanoma. The postoperative course was uncomplicated. She received two cycles of dacarbazine 1000 mg/day. Due to drug intolerance, the chemotherapy was discontinued. Now, she is receiving hospice care. PMID:24596522

    Only few case studies address pseudo-obstruction, a disorder - which often frustrates clinicians and patients due to an unclear diagnosis and limited therapeutic options. Thus, the aim of this paper is to investigate a relevant case concerning a patient presenting with symptoms of acquired chronic intestinal pseudo-obstruction (CIPO). After one year of extensive diagnostic tests and unsuccessful treatment with prokinetics, the patient underwent a subtotal ileocolectomy. The histology of the intestinal specimen revealed continuous atrophy and fibrosis mainly within the circular, inner muscle layer of muscularis propria of the ileum and colon. Even though serum markers were lacking, a subsequent skin biopsy showed signs of scleroderma supporting an initial diagnosis of intestinal involvement in systemic sclerosis. Despite treatment with steroids and methotrexate, the increasingly emaciated patient died. In conclusion, there is a bias against the publishing of pseudo-obstruction studies, in particular, due to the obscure underlying causes. To raise awareness of this problem, we call for clinicians to systematically generate comprehensive data about patients presenting these symptoms.

    2016-01-01

    Intestinal stem cells (ISCs) drive small intestinal epithelial homeostasis and regeneration. Mechanistic target of rapamycin (mTOR) regulates stem and progenitor cell metabolism and is frequently dysregulated in human disease, but its physiologic functions in the mammalian small intestinal epithelium remain poorly defined. We disrupted the genes mTOR, Rptor, Rictor, or both Rptor and Rictor in mouse ISCs, progenitors, and differentiated intestinal epithelial cells (IECs) using Villin-Cre. Mutant tissues and wild-type or heterozygous littermate controls were analyzed by histologic immunostaining, immunoblots, and proliferation assays. A total of 10 Gy irradiation was used to injure the intestinal epithelium and induce subsequent crypt regeneration. We report that mTOR supports absorptive enterocytes and secretory Paneth and goblet cell function while negatively regulating chromogranin A-positive enteroendocrine cell number. Through additional Rptor, Rictor, and Rptor/Rictor mutant mouse models, we identify mechanistic target of rapamycin complex 1 as the major IEC regulatory pathway, but mechanistic target of rapamycin complex 2 also contributes to ileal villus maintenance and goblet cell size. Homeostatic adult small intestinal crypt cell proliferation, survival, and canonical wingless-int (WNT) activity are not mTOR dependent, but Olfm4+ ISC/progenitor population maintenance and crypt regeneration postinjury require mTOR. Overall, we conclude that mTOR regulates multiple IEC lineages and promotes stem and progenitor cell activity during intestinal epithelium repair postinjury.—Sampson, L. L., Davis, A. K., Grogg, M.

    A small number of cases of small bowel obstruction caused by foods without the formation of phytobezoars have been reported. Repeated small bowel obstruction due to the ingestion of the same food is extremely rare. We present the case of 63-year-old woman who developed small bowel obstruction twice due to the ingestion of chestnuts without the formation of phytobezoars. This is the first reported case of repeated small bowel obstruction caused by chestnut ingestion. Careful interviews are necessary to determine the meal history of elderly patients and psychiatric patients.

    A 61-year-old eutrophic male was diagnosed with vitamin B12 deficiency and megaloblastic anemia. A modified Schilling test suggested intestinal malabsorption unrelated to intrinsic factor deficiency. Subsequent colonoscopy revealed the presence of a Taenia tapeworm. The anemia resolved within days under therapy with niclosamide and temporary vitamin B12 supplements. The present case suggests that, in addition to other well-known parasitic agents, e.g., Diphyllobothrium latum and Giardia lamblia, Taenia infestation can also be a cause of intestinal vitamin B12 malabsorption.

    AIMS—To document the long term course of chronic idiopathic intestinal pseudo-obstruction syndrome (CIIPS) in children with defined enteric neuromuscular disease, and the place and type of surgery used in their management; in addition, to identify prognostic factors.
METHODS—Children with CIIPS were investigated and treated prospectively.
RESULTS—Twenty four children presented congenitally, eight during the 1st year of life, and 10 later. Twenty two had myopathy and 16 neuropathy (11 familial). Malrotation was present in 16 patients, 10 had short small intestine, six had non-hypertrophic pyloric stenosis, and 16 had urinary tract involvement. Thirty two patients needed long term parenteral nutrition (TPN): for less than six months in 19 and for more than six months in 13, 10 of whom are TPN dependent; 14 are now enteral feeding. Prokinetic treatment improved six of 22. Intestinal decompression stomas were used in 36, colostomy relieved symptoms in five of 11, and ileostomy in 16 of 31. A poor outcome (death (14) or TPN dependence (10)) was seen with malrotation (13 of 16), short small bowel (eight of nine), urinary tract involvement (12 of 16), and myopathic histology (15 of 22).
CONCLUSIONS—In CIIPS drugs are not helpful but decompression stomas are. Outcome was poor in 24 of 44 children (15 muscle disorder, 10nerve disease).

    Gallstone ileus of the colon is an exceedingly rare cause of large-bowel obstruction. It is usually the result of fistula formation between the gallbladder and large bowel facilitating entry of the stone into gastrointestinal tract. Contrast enhanced abdominal computed tomography is an important diagnostic aid. Surgical management is the treatment of choice to prevent the disastrous complications of large-bowel obstruction. We describe the case of a 92-year-old man who presented with symptoms and signs of large-bowel obstruction. Radiological investigation showed a large gallstone impacted in the sigmoid colon. Open enterolithotomy was undertaken relieving the obstruction and the patient made a full recovery.

    In a double-blind, placebo-controlled, crossover trial, we investigated the effects of the prokinetic drug cisapride in patients with cystic fibrosis and chronic recurrent distal intestinal obstruction syndrome (DIOS). After a baseline period, 17 patients (12.9 to 34.9 years; 12 boys) received, in random order, cisapride (7.5 to 10 mg) and placebo three times daily by mouth, each for 6 months. Gastrointestinal symptoms (flatulence, abdominal pain, fullness, abdominal distension, nausea, anorexia, heartburn, diarrhea, vomiting and regurgitation) were scored three times monthly and physical examinations assessed. At baseline and at each 6-month period, assessment included food intake for 7 days, 3-day stool collection, pulmonary function tests, and abdominal radiographs. During cisapride therapy compared with placebo, there were significant reductions in flatulence (p less than 0.005), fullness, and nausea (p less than 0.05). Patients with the worst symptom scores benefited most from cisapride. With cisapride, 12 patients felt better and three worse (p less than 0.05); physicians judged 11 patients improved and two worse (p less than 0.05). No side effects were noted. There were no significant differences between cisapride and placebo periods in nutritional status, x-ray scores, pulmonary function, food intake (fat, protein, calories), stool size and consistency, and fecal losses of fat, bile acids, chymotrypsin, and calories. For acute episodes of DIOS, intestinal lavage was needed 6 times in 4 patients during treatment with cisapride, and 11 times in 6 patients receiving placebo. In comparison with unselected patients with cystic fibrosis and pancreatic insufficiency who were receiving enzyme supplements and who had no distal intestinal obstruction, fecal fat losses (percentage of intake) were almost twice as high in the study group with DIOS (31.2 +/- 20.6% vs 16.2 +/- 17.6%; p less than 0.01). We conclude that in the dosage used, long-term treatment with

    Background & Aims Chronic intestinal pseudo-obstruction (CIPO) is characterized by severe intestinal dysmotility that mimicks a mechanical sub-occlusion with no evidence of gut obstruction. We searched for genetic variants associated with CIPO to increase our understanding of its pathogenesis and indentify potential biomarkers. Methods We performed whole-exome sequencing of genomic DNA from patients with familial CIPO syndrome. Blood and lymphoblastoid cells were collected from patients and controls (individuals without CIPO); levels of mRNA and proteins were analyzed by quantitative reverse transcription PCR, immunoblot, and mobility shift assays. cDNAs were transfected into HEK293 cells. Expression of rad21 was suppressed in zebrafish embryos using a splice-blocking morpholino (rad21a MO). Gut tissues were collected and analyzed. Results We identified a homozygous mutation (p.622, encodes Ala>Thr) in RAD21 in patients from a consanguineous family with CIPO. Expression of RUNX1, a target of RAD21, was reduced in cells from patients with CIPO compared with controls. In zebrafish, suppression of rad21a reduced expression of runx1; this phenotype was corrected by injection of human RAD21 mRNA, but not with the mRNA from the mutated p.622 allele. rad21a MO zebrafish had delayed intestinal transit and greatly reduced numbers of enteric neurons, similar to patients with CIPO. This defect was greater in zebrafish with suppressed expression of ret and rad21, indicating their interaction in regulation of gut neurogenesis. The promoter region of APOB bound RAD21 but not RAD21 p.622 Ala>Thr; expression of wild-type RAD21 in HEK293 cells repressed expression of APOB, compared with control vector. The gut-specific isoform of APOB (APOB48) is overexpressed in sera from patients with CIPO who carry the RAD21 mutation. APOB48 is also overexpressed in sporadic CIPO in sera and gut biopsies. Conclusions Some patients with CIPO carry mutations in RAD21 that disrupt the ability of

  17. Dynamic left ventricular outflow tract obstruction: underestimated cause of hypotension and hemodynamic instability

    PubMed Central

    2014-01-01

    Left ventricular outflow tract obstruction, which is typically associated with hypertrophic cardiomyopathy, is the third most frequent cause of unexplained hypotension. This underestimated problem may temporarily accompany various diseases (it is found in even <1% of patients with no tangible cardiac disease) and clinical situations (hypovolemia, general anesthesia). It is currently assumed that left ventricular outflow tract obstruction is a dynamic phenomenon, the occurrence of which requires the coexistence of predisposing anatomic factors and a physiological condition that induces it. The diagnosis of left ventricular outflow tract obstruction should entail immediate implementation of the therapy to eliminate the factors that can potentially intensify the obstruction. Echocardiography is the basic modality in the diagnosis and treatment of left ventricular outflow tract obstruction. This paper presents four patients in whom the immediate implementation of bedside echocardiography enabled a rapid diagnosis of left ventricular outflow tract obstruction and implementation of proper treatment.

    Intestinal neuronal dysplasia type B (IND B) is an infrequent disease due to hyperplasia of the parasympathetic submucous plexus which causes alteration of intestinal motility, giving rise to symptoms of constipation and subocclusive manifestations. The disease is difficult to diagnose. It requires high clinical suspicion and should include differential diagnosis of patients with repeated subocclusive manifestations in order to make an early and correct diagnosis and avoid complications derived from unnecessary surgery that worsens the prognosis. We present the case of a 33-year-old Moroccan male who was admitted to our hospital on 2 occasions in 11 months, requiring total parenteral nutrition (TPN) for five months. The immunohistochemical analysis of the ileostomy and colostomy stoma led to a diagnosis of IND B. Eighteen months later, the patients is leading a normal life and has recovered the 25 kilos lost following the dietary indications and with the enzymatic supplements.

    Background/Aims Chronic intestinal pseudo-obstruction (CIPO) is a serious, life-threatening motility disorder that is often related to bacterial overgrowth. Fecal microbiota transplantation (FMT) results in restoration of the normal intestinal microbial community structure. We investigated the efficacy of FMT in the treatment of CIPO patients. Methods Nine patients (age 18–53 years) with CIPO were enrolled in this prospective, open-label study. Patients received FMT for 6 consecutive days through nasojejunal (NJ) tubes and were followed up for 8 weeks after treatment. We evaluated the rate of clinical improvement and remission, feeding tolerance of enteral nutrition, and CT imaging scores of intestinal obstructions. Lactulose hydrogen breath tests were performed before FMT and 8 weeks after FMT to evaluate for the presence small intestinal bacterial overgrowth (SIBO). Results FMT significantly alleviated bloating symptoms, and symptoms of pain were relieved 2 weeks after FMT. Enteral nutrition administered through a NJ tube after FMT was well-tolerated by 66.7% (6/9) of patients. CT scores of intestinal obstructions were significantly reduced after FMT (P = 0.014). SIBO was eliminated in 71.0% (5/7) of patients. Conclusions This pilot study demonstrated the safety of using FMT. FMT may relieve symptoms in selected patients with CIPO. FMT may also improve patient tolerance of enteral nutrition delivered via a NJ tube. PMID:27840368

    The effects of elevated intraluminal hydrostatic pressure on the active absorption of the amino acid selenium 75 L-methionine has been analyzed in the normal and obstructed small intestine. An intestinal loop of defined position and length was included in a recircling perfusion system from which the elimination rate of the radiolabeled amino acid was measured. Preset pressure levels within the system were maintained by a servo-controlled unit, which added or subtracted volume to keep the pressure constant. The rate of amino acid elimination increased when the nonobstructed loop was subjected to a pressure of 10 cm H2O but decreased when exposed to 20cm H2O. Using a loop of intestine subjected to 48 hours of obstruction, amino acid elimination was greatly retarded compared with that of the nonobstructed loop. By increasing the intraluminal pressure to 10 and 20 cm H2O, the elimination rate increased, equalling that of the nonobstructed gut. The results suggest that intestinal obstruction per se decreases active absorption secondary to impaired intestinal viability. Moderately increased intraluminal pressure adds a driving force to L-methionine absorption, the mechanism of which is obscure.

    A female infant born at 36 weeks gestational age with birthweight 2135 g, and who developed respiratory disorder, hyperlactacidemia and hypertrophic cardiomyopathy after birth, was admitted to hospital at 3 days of age. After admission, bilious emesis, abdominal distention, and passage disorder of the gastrointestinal tract were resistant to various drugs. Exploratory laparotomy was performed at 93 days of age, but no organic lesions were identified and normal Meissner/Auerbach nerve plexus was confirmed, which led to a clinical diagnosis of chronic intestinal pseudo-obstruction (CIPO). She was diagnosed with mitochondrial respiratory chain complex IV deficiency on histopathology of the abdominal rectus muscle and enzyme activity measurement. This is the first report of a neonate with mitochondrial respiratory chain complex deficiency with intractable CIPO. CIPO can occur in neonates with mitochondrial respiratory chain disorder, necessitating differential diagnosis from Hirschsprung disease.

    ABSTRACT Objectives To investigate a possible causal relationship for stone formation in pelviureteric junction obstruction and to outline management options. Materials and Methods A literature search and evidence synthesis was conducted via electronic databases in the English language using the key words pelviureteric junction obstruction; urolithiasis; hyperoxaluria; laparoscopic pyeloplasty; flexible nephroscopy; percutaneous nephrolithotomy, alone or in combination. Relevant articles were analysed to extract conclusions. Results Concomitant pelviureteric junction obstruction (PUJO) and renal lithiasis has been reported only scarcely in the literature. Although PUJO has been extensively studied throughout the years, the presence of calculi in such a patient has not received equal attention and there is still doubt surrounding the pathophysiology and global management. Conclusions Metabolic risk factors appear to play an important role, enough to justify metabolic evaluation in these patients. Urinary stasis and infection are well known factors predisposing to lithiasis and contribute to some extent. The choice for treatment is not always straightforward. Management should be tailored according to degree of obstruction, renal function, patient symptoms and stone size. Simultaneous treatment is feasible with the aid of minimally invasive operative techniques and laparoscopy in particular.

    The retinoblastoma 1 (RB1) tumor suppressor is a critical regulator of cell cycle progression and development. To investigate the role of RB1 in neural crest–derived melanocytes, we bred mice with a floxed Rb1 allele with mice expressing Cre from the tyrosinase (Tyr) promoter. TyrCre+;Rb1fl/fl mice exhibited no melanocyte defects but died unexpectedly early with intestinal obstruction, striking defects in the enteric nervous system (ENS), and abnormal intestinal motility. Cre-induced DNA recombination occurred in all enteric glia and most small bowel myenteric neurons, yet phenotypic effects of Rb1 loss were cell-type specific. Enteric glia were twice as abundant in mutant mice compared with those in control animals, while myenteric neuron number was normal. Most myenteric neurons also appeared normal in size, but NO-producing myenteric neurons developed very large nuclei as a result of DNA replication without cell division (i.e., endoreplication). Parallel studies in vitro found that exogenous NO and Rb1 shRNA increased ENS precursor DNA replication and nuclear size. The large, irregularly shaped nuclei in NO-producing neurons were remarkably similar to those in progeria, an early-onset aging disorder that has been linked to RB1 dysfunction. These findings reveal a role for RB1 in the ENS. PMID:24177421

    Chronic intestinal pseudo-obstruction (CIP) is an infrequent complication of an active systemic lupus erythematosus (SLE). We illustrate a case of SLE inactive-related CIP. A 51-year old female with inactive SLE (ECLAM score 2) was hospitalized with postprandial fullness, vomiting, abdominal bloating and abdominal pain. She had had no bowel movements for five days. Plain abdominal X-ray revealed multiple fluid levels and dilated small and large bowel loops with air-fluid levels. Intestinal contrast radiology detected dilated loops. CIP was diagnosed. The patient was treated with prokinetics, octreotide, claritromycin, rifaximin, azathioprine and tegaserod without any clinical improvement. Then methylprednisolone (500 mg iv daily) was started. After the first administration, the patient showed peristaltic movements. A bowel movement was reported after the second administration. A plain abdominal X-ray revealed no air-fluid levels. Steroid therapy was slowly reduced with complete resolution of the symptoms. The patient is still in a good clinical condition. SLE-related CIP is generally reported as a complication of an active disease. In our case, CIP was the only clinical demonstration of the SLE. PMID:21577309

    Abstract Ascaris lumbricoides infection affects approximately 1.5 billion people globally. Children with environmental and socio-economic risk factors are more susceptible to infestation, with serious complications such as intestinal obstruction (IO), volvulus, intussusception, and intestinal necrosis. We present the case of a 3-year-old girl who arrived at emergency department with abdominal pain and diarrhea for the last 3 days. The previous day she took an unspecified anthelmintic. Symptoms worsened with vomiting and diarrhea, with expulsion of roundworms through mouth and anus. Physical examination revealed bloating, absence of bowel sounds, abdominal tenderness, and a palpable mass in right hemi-abdomen. Abdominal radiographs showed air-fluid levels with mild bowel distention and shadows of roundworms. The diagnosis of IO by A lumbricoides. infestation was established and surgical approach scheduled. During exploratory laparotomy an intraluminal bolus of roundworms from jejunum to ascendant colon was evident. An ileum enterotomy was performed and worms were removed. Fluid therapy and antibiotics for 72 hours were administered, with posterior albendazol treatment for 3 days. Patient was uneventfully discharged on the tenth day. Reduction in parasitic load by means of improvements in sanitation, health education, and anthelmintic treatment must be implemented in endemic zones to prevent serious life-threatening complications by A lumbricoides. infestation, because some of them require urgent surgical treatment.

    Non-Hodgkin lymphoma is a rare cause of biliary obstruction. To the best of our knowledge, non-Hodgkin lymphoma in the peripancreatic region causing obstructive jaundice with simultaneous portal vein (PV) invasion has not yet been reported. We present a 50-year-old patient with obstructive jaundice whose extrahepatic portal vein was obstructed by the invasion of a peripancreatic non-Hodgkin lymphoma. The patient denied any other symptoms such as recurrent fever, night sweat and loss of body weight. Computed tomography (CT) revealed a 10 cm mass in the retroperitoneal space behind the head of the pancreas causing obstruction of the distal bile duct and the PV. A pylorus-preserving pancreaticoduodenectomy combined with a PV resection was performed. The PV was reconstructed using an autologous right internal jugular vein graft. The resected specimen showed endoluminal invasion of both the bile duct and the PV. Histological examination showed the mass consisting of diffuse sheets of large malignant lymphoid cells. These cells were positive for CD20 and CD79a, partially positive for CD10, and negative for CD3, CD4, CD5, CD8 and CD30. The pathologic diagnosis was diffuse large B-cell type non-Hodgkin lymphoma and the patient was transferred to the Department of Hematology and Oncology for chemotherapy. He received four cycles of combined chemotherapy including cyclophosphamide, doxorubicin, vincristine and prednisone plus rituximab, and three cycles of intrathecal chemoprophylaxis including methotorexate, cytosine arbinoside and prednisone. The patient is alive with no evidence of the disease for 7 mo after operation and will receive additional courses of chemotherapy.

    Aneuploidy is associated with a variety of diseases such as cancer and microcephaly. Although many studies have addressed the consequences of a non-euploid genome in cells, little is known about their overall consequences in tissue and organism development. Here we use two different mutant conditions to address the consequences of aneuploidy during tissue development and homeostasis in Drosophila. We show that aneuploidy causes brain size reduction due to a decrease in the number of proliferative neural stem cells (NSCs), but not through apoptosis. Instead, aneuploid NSCs present an extended G1 phase, which leads to cell cycle exit and premature differentiation. Moreover, we show that this response to aneuploidy is also present in adult intestinal stem cells but not in the wing disc. Our work highlights a neural and intestine stem cell-specific response to aneuploidy, which prevents their proliferation and expansion. PMID:26573328

    The article reviews the intestinal ischemia theme on newborn and children. The intestinal ischemia may be either acute - intestinal infarction (by vascular obstruction or by reduced mesenteric blood flow besides the occlusive mechanism), either chronic. In neonates, acute intestinal ischemia may be caused by aortic thrombosis, volvulus or hypoplastic left heart syndrome. In children, acute intestinal ischemia may be caused by fibromuscular dysplasia, volvulus, abdominal compartment syndrome, Burkitt lymphoma, dermatomyositis (by vascular obstruction) or familial dysautonomia, Addison's disease, situs inversus abdominus (intraoperative), burns, chemotherapy administration (by nonocclusive mesenteric ischemia). Chronic intestinal ischemia is a rare condition in pediatrics and can be seen in abdominal aortic coarctation or hypoplasia, idiopathic infantile arterial calcinosis.

    Cellulose fiber diet pills have recently become a popular form of weight control. In the past 2 months, we have seen two patients in whom ingestion of these pills has resulted in complete distal esophageal obstruction. Further studies revealed that each patient had a previously undiagnosed anatomical abnormality of the distal esophagus; in one case a Schatzki's ring, and in the other a stricture probably secondary to chronic reflux. We conclude that patients with known esophageal narrowing, or with a history of reflux and/or dysphagia, should use cellulose fiber diet pills only with extreme caution.

    We report a case of non-identical twins who presented with identical neonatal intestinal obstruction with features of anorectal stenosis, presacral mass and sacral anomaly consistent with Currarino's syndrome or triad. Plain sacral radiograph, contrast enema and MRI were diagnostic. Initial management involved a defunctioning colostomy followed by a posterior sagittal anorectoplasty with excision of the teratoma ± anterior sacral meningocele and finally closure of colostomy in a staged multidisciplinary approach. The twins' father is also affected with features of Currarino's syndrome but was diagnosed during family screening. Currarino's syndrome presenting with identical neonatal low intestinal obstruction in a non-identical set of twins is rare and interesting. Antenatal diagnosis of Currarino's syndrome is difficult and may prove to be a challenge even in the postnatal period. Sacral spine radiograph, contrast enema and MRI are diagnostic. Management requires high index of suspicion, low threshold for MRI and multidisciplinary staged approach.

    Small bowel obstruction due to undigested fibre from fruits and vegetables is a rare but known medical condition. We report a case of small bowel obstruction caused by a whole cherry tomato in a patient without a past medical history of abdominal surgery. A 66-year-old man presented to the emergency department complaining of lower abdominal pain with nausea and vomiting. His last bowel movement had occurred on the morning of presentation. He underwent abdominal computed tomography (CT), which showed a sudden change of diameter in the distal ileum with complete collapse of the proximal small bowel segment. Laparoscopy confirmed a small bowel obstruction with a transition point close to the ileocaecal valve. An enterotomy was performed and a completely undigested cherry tomato was retrieved. To our knowledge, this is the first reported case of a small bowel obstruction caused by a whole cherry tomato.

    Sodium polystyrene sulfonate (Kayexalate) and calcium polystyrene sulfonate (CPS, Kalimate) are commonly used to reduce serum potassium. There were some published evidences of severe gastrointestinal complications from the administration of these agents such as colonic necrosis with or without perforation and acute obstruction. The authors reported a 52-year-old male patient being critically ill from severe soft tissue infection of the right leg and sepsis. Hyperkalemia had occurred due to renal insufficiency and required several doses of Kalimate to reduce the serum potassium level. Subsequently, the patient developed complete intestinal obstruction and an exploratory laparotomy was performed. The intra-operative findings were distended stomach and the small bowel contained a large amount of intraluminal affected Kalimate that was removed via gastrotomy and enterotomy. These findings suggested that the inspissated Kalimate could lead to significant obstruction of the gastrointestinal tract in some groups of patient.

    The aim of the present study was to investigate intestinal mucosal barrier dysfunction in a rat model of chronic obstructive pulmonary disease (COPD). Male Sprague Dawley rats (n=40) were evenly randomized into control and COPD groups and the COPD model was established by regulated exposure to cigarette smoke for 6 months. Histopathological changes of the lung and intestinal tissues were detected by hematoxylin and eosin staining. Expression of the tight junction proteins occludin and zona occludens-1 (ZO-1) in the intestinal tissues were analyzed by western blotting, serum diamine oxidase (DAO) activity was detected by spectrophotometry, the urinary lactulose to mannitol ratio (L/M) was evaluated by high performance liquid chromatography, and intestinal tissue secretion of tumor necrosis factor (TNF)-α, interferon (IFN)-γ and interleukin (IL)-8 were detected by ELISA. Lung histopathology revealed thinned alveolar walls, ruptured alveolar septa, enlarged and deformed alveoli, and the formation of bullae and emphysema due to alveolar fusion in the COPD group, while intestinal histopathology indicated clearly swollen intestines with darkened and gray mucosa, neutrophil infiltration of the intestinal mucosal and regional epithelial shedding. The occludin and ZO-1 expression levels were significantly lower in the COPD group compared with those in the corresponding control group (P<0.05), while the urinary L/M ratio was significantly higher (P<0.05). Furthermore, the serum DAO activity and secretion of TNF-α, IFN-γ and IL-8 in the intestinal tissues were significantly higher in the COPD group than in the control group (each P<0.05). Dysfunctional and structural changes were observed in the intestinal mucosal barrier in COPD model rats, which may be associated with the increased intestinal inflammatory responses. PMID:27588054

  18. Intestinal gases and flatulence: possible causes of occurrence.

    PubMed

    All gases entrapped in closed body cavities are destined to be partially or completely absorbed. Intestinal gases often accumulate and cause flatulence. This paper proposes a simple concept of intestinal gas occurrence based on our knowledge on gas resorption in other body cavities. Compliance of intestinal and abdominal walls makes pressure in the liquid chyme bubbles near 760 mmHg. Intestinal gases are from three sources. Air can be swallowed, CO2 come from the gastric acid neutralisation and from intestinal bacterial colonies that also produce hydrogen and methane. In continuously mixed liquid chyme, the total pressure of blood gases is similar or lower than in the venous blood (or=760 mmHg). Some local production of bacterial gases with partial pressure of more than 90 mmHg is required, so the resulting small bowel bubbles would contain less than 20% of bacterial gases. If peristaltic mixing of chyme is prevented by an obstacle, local pressures of bacterial gases build up, form bubbles that fuse and finally make X-ray visible aeroliquid levels. Bacterial gases make almost 3/4 of the flatulence. Formation of bubbles destined to become flatulence might depend on altered rheological condition of the large bowel content, with local abundant production of bacterial gases near bacterial colonies. Gases are unable to diffuse rapidly through the dense liquid content and local accumulation allows formation of bubbles mainly of bacterial gases. Their pressure can be higher 760 mmHg, since they are stretching the thick content. Poor diffusion of gases keeps them almost free of blood gases and their entrance makes them bigger. As the content moves along the colon, the content is becoming more solid and gases are becoming entrapped in large bubbles. Some blood and bacterial gases are absorbed and exhaled, but the remaining quantity has no other escape except flatulence. Flatulence rich in bacterial gases might be the price

    Abstract Objective: The present report aimed to present a unique case of idiopathic retroperitoneal fibrosis (RPF) presenting features of unilateral ureteral and sigmoid colon obstruction. RPF is a rare disorder with unclear etiology. Case report: A 43-year-old female had a 10-day history of lower right abdominal and lumbar pain. Gynecological examination, ultrasound, and computed tomography (CT) were all suggestive of right ovarian tumor. An enhanced CT showed right-sided hydronephrosis. The patient was diagnosed as having ovarian cancer. Ten days after hospitalization, a right intraureteral stent with a double-J catheter was inserted. Upon exploring the abdomen, unyielding RPF was encountered. A partial sigmoidectomy and colostomy were performed. Postoperative pathological results suggested idiopathic RPF. She received steroid treatments. Conclusion: RPF is a rare disease that can be misdiagnosed. Our understanding about its presentation has to be improved and it should be considered as a differential diagnosis for patients presenting with abdominal diseases. PMID:28207528

    Abstract Background: Transcaval inferior vena cava (IVC) filter penetration involving the urinary tract is rare, but has been previously reported. We herein present unique management of symptomatic hydronephrosis secondary to erosion of an IVC filter limb into the lumen of the proximal right ureter. Case Presentation: A 59-year-old woman presented with abdominal and right flank pain in October 2015 and was found to have right hydronephrosis, apparently secondary to obstruction from erosion of an IVC filter limb into the proximal right ureter. This was effectively managed with percutaneous, endovascular, and endourologic procedures, without the need for a major invasive surgical procedure. Conclusion: Endovascular removal of the IVC filter was performed safely in this case and can be considered when the urinary tract is involved in filter erosion. PMID:27579443

    Axial torsion and necrosis of Meckel's diverticulum causing simultaneous mechanical small bowel obstruction are the rarest complications of this congenital anomaly. This kind of pathology has been reported only eleven times. Our case report presents this very unusual case of Meckel's diverticulum. A 41-year-old man presented at the emergency department with complaints of crampy abdominal pain, nausea and retention of stool and gases. Clinical diagnosis was small bowel obstruction. Because the origin of obstruction was unknown, computer tomography was indicated. Computed tomography (CT)-scan revealed dilated small bowel loops with multiple air-fluid levels; the oral contrast medium had reached the jejunum and proximal parts of the ileum but not the distal small bowel loops or the large bowel; in the right mid-abdomen there was a 11 cm × 6.4 cm × 7.8 cm fluid containing cavity with thickened wall, which was considered a dilated bowel-loop or cyst or diverticulum. Initially the patient was treated conservatively. Because of persistent abdominal pain emergency laparotomy was indicated. Abdominal exploration revealed distended small bowel loops proximal to the obstruction, and a large (12 cm × 14 cm) Meckel's diverticulum at the site of obstruction. Meckel's diverticulum was axially rotated by 720°, which caused small bowel obstruction and diverticular necrosis. About 20 cm of the small bowel with Meckel's diverticulum was resected. The postoperative course was uneventful and the patient was discharged on the fifth postoperative day. We recommend CT-scan as the most useful diagnostic tool in bowel obstruction of unknown origin. In cases of Meckel's diverticulum causing small bowel obstruction, prompt surgical treatment is indicated; delay in diagnosis and in adequate treatment may lead to bowel necrosis and peritonitis.

    Enterolith formation is a rare cause of afferent limb obstruction following Billroth II gastrectomy and Roux-en-Y hepaticojejunostomy surgery. A case of ascending cholangitis caused by an enterolith incarcerated in the afferent loop of a 15-year-old Roux-en-Y hepaticojejunostomy was emergently decompressed under direct ultrasound guidance prior to surgery. This is the thirteenth reported case of an enterolith causing afferent loop obstruction. A discussion of our management approach and a review of the relevant literature are presented.

    Mechanical obstruction of the biliary tree and resultant stasis are the cornerstone of a spectrum of diseases ranging from biliary colic to fulminant cholangitis. Infrequently acquired abnormalities of the abdominal vasculature can lead to biliary obstruction. In 2010, we reported a case of acute cholangitis resulting from compression of extra hepatic bile duct by an abdominal aortic aneurysm (AAA). We subsequently conducted a follow up scoping review of literature to identify other cases of acquired abdominal arterial abnormalities resulting in biliary obstruction looking at their management and outcomes. The articles were independently reviewed by two of the authors and pertinent data was extracted. The data was divided on an anatomic basis into two groups: one with primary aortic pathology and one with splanchnic vessel pathology. We identified 39 cases of biliary obstruction secondary to acquired aortic or splanchnic vessel abnormalities; 16 were caused by AAAs and 23 by splanchnic vessels. The cases were managed via conservative, endoscopic, endovascular or open surgical options based on the available technology and expertise. Although uncommon, recognition of aortic and splanchnic arterial abnormalities as a potential cause of biliary obstruction is important as management entails not only cautious decompression of the biliary tree but also addressing the underlying vascular pathology. We recommend that extrinsic biliary compression by an aneurysm or pseudoaneurysm be considered among the differential diagnosis in patients presenting with biliary obstruction and a known lesion of the abdominal vasculature.

    Disc herniation into the intervertebral foramen (IVF) or osteophytic outgrowths from the margins of the apophyseal joints that project into the IVF may compress the neural structures, but in this cadaveric study of 160 lumbar foramens (age range, 35-91 years), the authors have found that they were much more commonly associated with compression and distortion of the large venous plexus within the IVF. In the absence of direct nerve compression (seen in only eight specimens), the most severe neural changes were associated with compression, congestion, and resultant dilatation of foraminal veins. Pathologic changes within and around the nerve root complex included peri- and intraneural fibrosis, edema of nerve roots, and focal demyelination. Inflammatory cells were notably absent. Vascular changes within the thickened fibrous sheath about damaged nerves, namely, basement membrane thickening, suggestive of endothelial cell injury also were observed. The association between vascular compression, tissue fibrosis, and endothelial injury distant from the compression may be causal--probably due to ischemia as a result of reduced venous outflow. Such observations have led the authors to propose that venous obstruction may be an important pathogenic mechanism in the development of perineural and intraneural fibrosis.

    Physicians are educated with the classical teaching that symptomatic patients with Meckel's diverticulum (MD) most often present with painless rectal bleeding. However, a review of the literature reveals that young patients with MD will most commonly present with signs of intestinal obstruction, an etiology not frequency considered in patients presenting to the emergency department with obstruction. We present two cases of intestinal obstruction diagnosed in our emergency department, with Meckel's diverticulum being the etiology. PMID:26788380

    We describe a case of proximal small bowel obstruction caused by an occlusive thrombus as a result of bleeding from a duodenal ulcer, which is likely to be stress induced. Initial presentation was confused as a bleeding duodenal ulcer and resultant ileus. Such reports are incredibly rare in the literature and never has one been reported as a result of a stress ulcer. Obstructive symptoms in the acute postoperative patient may be confused for an ileus but mechanical causes must be excluded. The presence of upper gastrointestinal bleeding must not detract from that possibility. Future identification of an occlusive clot on endoscopy that is impossible to circumnavigate may benefit from intraluminal injection of thrombolytic agents to prevent obstruction but this must be weighed with the risk of exacerbating any bleeding. Clearly a risk versus benefit analysis will be necessary on an individual basis. PMID:24960721

    Fecaloma is a mass of hardened feces being impacted mostly in rectum and sigmoid. The most common sites of the fecaloma is the sigmoid colon and the rectum. There are several causes of fecaloma and have been described in association with Hirschsprung's disease, psychiatric patients, Chagas disease, both inflammatory and neoplastic, and in patients suffering with chronic constipation. Up to now several cases of giant fecaloma has been reported in the literature most of them presenting with megacolon or urinary retention. We herein report a case of giant fecaloma leading to bowel obstruction who was successfully treated by surgery. A 30-yrar-old man presented with sign and symptoms of acute bowel obstruction. He underwent exploratory laparotomy and enterotomy. He was found to have a giant fecaloma causing bowel obstruction in the jejunum. He was discharged after the operation with good condition. Jejunal fecaloma is extremely rare condition.

    Malignant obstruction develops frequently in advanced gastric cancer. Although it is primarily the gastric outlet that is obstructed, there are occasional reports of colonic obstruction. Treating intestinal obstruction usually requires emergency surgery or stent insertion. There are several kinds of complications with stent insertion, such as bowel perforation, stent migration, bleeding, abdominal pain and reobstruction. Nevertheless, endoscopic stent insertion could be a better treatment than emergency surgery in cases of malignant bowel obstruction in cancer patients with poor performance status. We report a case of advanced gastric cancer with carcinomatosis in which a recurrent colonic stent was inserted at the same site because of cancer growth into the stent. The patient maintained a good condition for chemotherapy, thus improving their chances for survival. PMID:19430568

    We report on two patients with recurrent episodes of chronic intestinal pseudo-obstruction (CIPO). A 50-year-old woman with severe multiple sclerosis and an 84-year-old man with Parkinson's disease and dementia had multiple hospital admissions because of pain and distended abdomen. Radiographic and endoscopic findings showed massive dilation of the colon without any evidence of obstruction. Conservative management resolved symptoms only for a short period of time. As these patients were poor candidates for any surgical treatment we carried out percutaneous endoscopic colostomy by placing a 20-Fr tube in the cecum with the introducer method. The procedure led to durable symptom relief without complications. We present these two cases and give a review through the existing literature of the procedure in CIPO.

    Chronic obstructive pulmonary disease is characterised by oxidative stress, but little is known about the associations between antioxidant status and all-cause mortality in adults with this disease. The objective of the present study was to examine the prospective associations between concentrations of α- and β-carotene, β-cryptoxanthin, lutein/zeaxanthin, lycopene, Se, vitamin C and α-tocopherol and all-cause mortality among US adults with obstructive lung function. Data collected from 1492 adults aged 20–79 years with obstructive lung function in the National Health and Nutrition Examination Survey III (1988–94) were used. Through 2006, 629 deaths were identified during a median follow-up period of 14 years. After adjustment for demographic variables, the concentrations of the following antioxidants modelled as continuous variables were found to be inversely associated with all-cause mortality among adults with obstructive lung function: α-carotene (P=0.037); β-carotene (P=0.022); cryptoxanthin (P=0.022); lutein/zeaxanthin (P=0.004); total carotenoids (P=0.001); vitamin C (P<0.001). In maximally adjusted models, only the concentrations of lycopene (P=0.013) and vitamin C (P=0.046) were found to be significantly and inversely associated with all-cause mortality. No effect modification by sex was detected, but the association between lutein/zeaxanthin concentrations and all-cause mortality varied by smoking status (Pinteraction = 0.048). The concentrations of lycopene and vitamin C were inversely associated with all-cause mortality in this cohort of adults with obstructive lung function. PMID:25315508

    Objective Patients’ beliefs about the causes of their illness have been associated with emotional adjustment and behavioral outcomes in several medical conditions; however, few studies have examined illness attributions among patients with COPD. In the current study, patterns of patients’ causal attributions for COPD were identified and examined in relation to health behaviors and symptoms. Method Three-hundred and ninety-four patients with COPD and ≥10 pack year history of smoking completed a self-report questionnaire that included the Illness Perception Questionnaire- Revised (IPQ-R). Results A factor analysis of the IPQ-R cause items using principal axis factoring yielded four individual items (i.e., smoking, heredity, pollution, and personal behavior) and one large factor that was primarily driven by psychological attributions. Ninety-three percent of patients agreed or strongly agreed that smoking was a cause of their COPD. Higher scores on the large IPQ-R factor were associated with reduced quality of life (r=.25, p<.001) and symptoms of anxiety (r=.33, p<.001) and depression (r=.31, p<.001), indicating that patients who attributed their COPD to psychological factors were more likely to have poorer emotional adjustment and quality of life. Conclusions Our finding of one large factor with several stand-alone items is in contrast with previous research that has derived a multi-factor structure for the cause items of the IPQ-R in other chronic illness populations. This difference may be due to the importance of smoking, environmental exposures, and heredity in the development of COPD. Future research should expand upon these specific attributions in COPD‥ PMID:21511077

    A 77-year-old man hospitalized for epigastric pain showed jaundice of the skin and conjunctivae. Laboratory tests revealed elevated hepatobiliary enzymes and inflammatory markers, and imaging studies demonstrated a 12 cm hepatic cyst compressing the common bile duct. The diagnosis was a giant hepatic cyst causing obstructive jaundice. Cyst drainage and sclerotherapy with 5% monoethanolamine oleate was performed twice, resulting in almost complete disappearance of the cyst. Obstructive jaundice due to a hepatic cyst, as seen in this case, is relatively rare and this report includes a review of other similar cases in Japan.

    Medical management of systemic sclerosis (SSc)-associated chronic intestinal pseudo- obstruction (CIPO) has often proved inadequate. Percutaneous endoscopic colostomy (PEC) has been proposed as a method of treatment, but it is associated with a relatively high incidence of serious complications. We report herein a very severe case of SSc-associated CIPO in which complications were successfully controlled by long tube placement via a gastrostomy. Transgastric long tube placement may offer a relatively safe alternative to PEC in treating severe SSc-associated CIPO.

    The purpose of this study was to determine whether nitric oxide (NO) is present in clinically normal horses under basal conditions and if it increases secondary to naturally acquired small intestinal strangulation obstruction. Thirty-one horses were used; 20 horses with naturally acquired small intestinal strangulation obstruction and 11 clinically normal horses with no signs of gastrointestinal tract disease. Jugular venous blood, abdominal fluid, and urine were collected for NO quantification. Plasma, abdominal fluid, and urine were stored at -70 degrees C until analyzed for NO using a chemiluminescent method. Biopsy specimens collected from the affected jejunal segment, during anesthesia or after immediately after euthanasia, or from the midjejunum of control horses, were divided into subsections for fixation in zinc formalin and cryopreservation in OCT gel. Nicotinamide adenine dinucleotide phosphate (reduced) (NADPH) diaphorase histochemical stains were performed on cryopreserved tissues and inducible nitric oxide synthase (iNOS) and nitrotyrosine immunohistochemical stains were performed on formalin-fixed, paraffin-embedded tissues. There were significantly greater plasma and abdominal fluid NO concentrations in affected horses as compared with controls, but there were no significant differences between horses for urine NO concentrations. There was a significant decrease in NADPH diaphorase stain in mucosal epithelium, vasculature, and leukocytes, and in submucosal plexi in affected horses compared with control horses. There was a significant increase in iNOS staining in mucosal and submucosal leukocytes and in mucosal leukocyte nitrotyrosine staining of the affected compared with control horses. Endothelial NOS and neuronal NOS are present under basal conditions in the jejunum of horses and probably mediate physiologic or cytoprotective effects. Plasma and abdominal fluid, but not urine, NO concentrations increase subsequent to small intestinal strangulation

    We report a case of a post-tracheotomy suprastomal granuloma in the early postoperative phase that caused subacute airway obstruction in a 28-year-old woman. The patient had undergone the tracheotomy during the surgical treatment of a submental abscess. During recovery, several capping trials had failed. Therefore, direct laryngoscopy was performed on postoperative day 11, and it revealed that the airway was being obstructed by a tracheal granuloma. The granuloma was managed with a partial resection and corticosteroids. The patient was successfully decannulated with no recurrence of the granuloma. To the best of our knowledge, airway obstruction secondary to a tracheal granuloma has not been previously reported as an early complication of a traditional surgical tracheotomy in an adult. In this report, we discuss the presenting features of this case and we propose several possible etiologies.

    The purpose of this study was to determine the spectrum of findings and the frequency of apparent distal colonic obstruction on abdominal radiographs in women with obstructive symptoms following Caesarean section. A search of radiology files yielded 21 patients who had abdominal radiographs because of obstructive symptoms during the early post-operative period. The radiographs were reviewed retrospectively to characterize the bowel gas patterns in these patients. Medical records were also reviewed to determine the treatment and patient course. Abdominal radiographs showed findings suggestive of distal colonic obstruction in 15 patients (71%), small bowel obstruction in 2 (10%), adynamic ileus in 3 (14%) and a normal bowel gas pattern in 1 (5%). In all 15 patients with apparent distal colonic obstruction, there was minimal or no gas in the rectosigmoid, with an associated pelvic mass representing the enlarged post-partum uterus, which compressed the rectosigmoid and prevented it from filling with gas. All 21 patients had rapid clinical or radiographic improvement on conservative management, indicating a transient post-operative ileus. Radiologists should be aware of the limitations of abdominal plain radiographs following Caesarean section so that a post-operative ileus is not mistaken for a distal colonic obstruction and conservative measures can be undertaken to decompress the bowel until the ileus resolves.

  17. The nature and causes of chronic obstructive pulmonary disease: A historical perspective

    PubMed Central

    Warren, C Peter W

    2009-01-01

    Chronic obstructive pulmonary disease (COPD) is the currently favoured name for the diseases formerly known as emphysema and bronchitis. COPD has been recognized for more than 200 years. Its cardinal symptoms are cough, phlegm and dyspnea, and its pathology is characterized by enlarged airspaces and obstructed airways. In the 19th century, the diagnosis of COPD depended on its symptoms and signs of a hyperinflated chest, and reduced expiratory breath sounds. The airflow obstruction evident on spirometry was identified in that century, but did not enter into clinical practice. Bronchitis, and the mechanical forces required to overcome its obstruction, was believed to be responsible for emphysema, although the inflammation present was recognized. The causes of bronchitis, and hence emphysema, included atmospheric and domestic air pollution, as well as dusty occupations. Cigarette smoking only became recognized as the dominant cause in the 20th century. The lessons learned of the risks for COPD in 19th-century Britain are very pertinent to the world today.

    We carried out a retrospective analysis of medical files to evaluate causes of chronic renal failure in 80 children (M--49, F--31), age 1 month to 20 years) who started renal replacement therapy in the Department of Nephrology and Dialysis of the Polish Mothers Memorial Hospital in the years 1990-2007. In 28 children (35%) reflux and obstructive nephropathy was a cause of renal failure. In 5 children the disease was secondary to the neurogenic bladder. The incidence of these nephropathies in our population was constant in the analyzed years. In our group there were 2 neonates and 7 adolescent who were diagnosed with nephropathy as late as in the endstage phase. Boys with posterior urethral valve required renal replacement therapy earlier (146 +/- 55 months). We conclude that obstructive and reflux nephropathy are still the essential cause of end stage renal disease in children.

    Percutaneous endoscopic colostomy (PEC), using the classic pull-through technique in the ascending or the descending colon, has been proven useful to treat chronic intestinal pseudo-obstruction. We report the case of a high-surgical risk 70-year-old male with refractory chronic intestinal pseudo-obstruction, in whom the ascending colon could not be reached due to tortuous left dolichocolon. Endoscopic-assisted colopexy and push colostomy in the proximal transverse colon was decided accordingly. Colopexy was performed under direct endoscopic vision in the proximal transverse colon using 3 preloaded T-fasteners surrounding the intended stoma site. The stoma tract was created with an introducer needle, allowing the advance of the 24 Fr 4-sleeve dilator over a guidewire. Afterwards, the dilator was removed and the peel-away sheath was left in place. Over the guidewire, a 20-Fr gastrostomy tube was advanced into the colon lumen through the covering, which was finally removed. The patient recovered uneventfully, despite postprocedure pneumoperitoneum, which was related to the technique. He died a month later due to unrelated comorbidities, without further abdominal complaints after discharge. This is the first report of PEC both using a push technique, and the first report in a different location than the ascending or the descending colon. We believe this novel push technique may be feasible for PEC, avoiding the need of reinsertion in patients with difficult colonoscopy.

    Small bowel obstruction and large bowel obstruction account for approximately 20% of cases of acute abdominal surgical conditions. The role of the radiologist is to answer several key questions: Is obstruction present? What is the level of the obstruction? What is the cause of the obstruction? What is the severity of the obstruction? Is the obstruction simple or closed loop? Is strangulation, ischemia, or perforation present? In this presentation, the radiologic approach to and imaging findings of patients with known or suspected bowel obstruction are presented.

  1. Two Cases of Chronic Intestinal Pseudo-obstruction: A Comparison of Staining Characteristics of Enteric Visceral Myopathy With Hirschsprung Disease.

    2016-09-01

    Chronic intestinal pseudo-obstruction (CIPO), a rare, debilitating disorder of bowel motility dysfunction, is largely a clinical diagnosis, without any universally accepted diagnostic criteria. Three subgroups are generally acknowledged based on the cell-type affected: enteric visceral myopathy (the most common subgroup), neuropathy, and mesenchymopathy. A fourth subgroup includes abnormalities of neurohormonal peptides. Although immunohistochemical staining is reportedly useful for identifying the mesenchymopathic type, its role in diagnosing enteric visceral myopathy and neuropathy has been fraught with difficulties. We present two cases of chronic intestinal pseudo-obstruction that are clinically and histopathologically suggestive of type III visceral enteric myopathy, aiming to expound upon the diagnostic and pathogenic features. We found that the outer-longitudinal layer of the muscularis propria was more severely affected as compared with the inner circular layer. To investigate the value of this finding, we performed immunostains in the one case in which a paraffin block was available. We found increased peripherin and calretinin immunopositive nerve fibers in the outer layer as compared with inner, but without any significant increase in S-100 positivity or alteration in neuronal morphology of myenteric plexus, a novel finding. This differential staining pattern was completely different from Hirschsprung disease, in which we found rare to absent peripherin and calretinin staining. It is unclear if this increase in the outer layer in visceral myopathy reflects a reactive change or dysfunctional axons. In addition, the history of volvulus in one patient and transmural inflammatory changes in the second raise concerns about the higher propensity of clinical complications secondary to the attenuated outer muscular layer. This study suggests that enteric visceral myopathy has histologic and staining characteristics different from Hirschsprung disease, a finding

Thermographic images represent the propagation of heat in micro-environmental systems. The objective of this study was to investigate the use of thermographic images to document the changes on the small intestine meridian (S.I.M.) when submitted to laser acupuncture. Another important issue regards to the analysis of the flow direction if it is upward when stimulated by acupuncture points. For the execution of this work, a laser acupuncture pen was used in points of the meridian in the S.I.M. Two healthy male volunteers were selected (18 and 60 years old, respectively), and doses of 576,92 J/cm(2) with low-power infrared laser equipment with a wavelength of 780 nm in the SI.3 and SI.19 points were applied. An infrared thermal camera was used to measure the temperature of the S.I.M. during the 6 min laser acupuncture pen stimulus. When the laser acupuncture of both volunteers was conducted in the SI.3 point, it presented hyper-radiation of the hemi face in the same side, far from the application site. When this was applied in the SI.19 point, hyper-radiation in the same point and temperature lowering at the end of the meridian were observed. The laser energy caused thermal changes along the path of the S.I.M., distal, and proximal at the same time, proving the existence of the S.I.M.

    A 26-year-old woman was referred to our hospital because of abdominal distention and vomiting. Contrast-enhanced computed tomography showed a blind loop of the bowel extending to near the uterus and a fibrotic band connecting the mesentery to the top of the bowel, suggestive of Meckel’s diverticulum (MD) and a mesodiverticular band (MDB). After intestinal decompression, elective laparoscopic surgery was carried out. Using three 5-mm ports, MD was dissected from the surrounding adhesion and MDB was divided intracorporeally. And subsequent Meckel’s diverticulectomy was performed. The presence of heterotopic gastric mucosa was confirmed histologically. The patient had an uneventful postoperative course and was discharged 5 d after the operation. She has remained healthy and symptom-free during 4 years of follow-up. This was considered to be an unusual case of preoperatively diagnosed and laparoscopically treated small-bowel obstruction due to MD in a young adult woman. PMID:26981191

    Probiotic is a preparation containing microorganisms that confers beneficial effect to the host. This work assessed whether oral treatment with viable or heat-killed yeast Saccharomyces cerevisiae strain UFMG 905 prevents bacterial translocation (BT), intestinal barrier integrity, and stimulates the immunity, in a murine intestinal obstruction (IO) model. Four groups of mice were used: mice undergoing only laparotomy (CTL), undergoing intestinal obstruction (IO) and undergoing intestinal obstruction after previous treatment with viable or heat-killed yeast. BT, determined as uptake of (99m)Tc-E. coli in blood, mesenteric lymph nodes, liver, spleen and lungs, was significantly higher in IO group than in CTL group. Treatments with both yeasts reduced BT in blood and all organs investigated. The treatment with both yeasts also reduced intestinal permeability as determined by blood uptake of (99m)Tc-DTPA. Immunological data demonstrated that both treatments were able to significantly increase IL-10 levels, but only viable yeast had the same effect on sIgA levels. Intestinal lesions were more severe in IO group when compared to CTL and yeasts groups. Concluding, both viable and heat-killed cells of yeast prevent BT, probably by immunomodulation and by maintaining gut barrier integrity. Only the stimulation of IgA production seems to depend on the yeast viability.

    Occupational inhalative exposures contribute to a significant proportion of obstructive airway diseases (OAD), namely chronic obstructive pulmonary disease (COPD) and asthma. The number of occupational OAD in the German industrial sector for the year 2003 are presented. Other analyses of surveillance data were retrieved from Medline. Most confirmed reports of OAD are cases of sensitizer induced occupational asthma (625 confirmed cases) followed by COPD in coal miners (414 cases), irritant induced occupational asthma (156 cases), and isocyanate asthma (54 cases). Main causes of occupational asthma in Germany comprise flour/flour constituents (35.9%), food/feed dust (9.0%), and isocyanates (6.5%). Flour and grain dust is a frequent cause of occupational asthma in most European countries and South Africa. Isocyanates are still a problem worldwide. Although wide differences in the estimated incidences between countries exist due to deficits in the coverage of occupational OAD, the high numbers necessitate improvement of preventive measures.

    Background The aim of this study was to evaluate the curative effect of transvaginal mesh repair (TVMR) and stapled transanal rectal resection (STARR) in treating outlet obstruction constipation caused by rectocele. Material/Methods Patients who had outlet obstruction constipation caused by rectocele were retrospectively analyzed and 39 patients were enrolled the study. Patients were assigned to either the TVMR or STARR group. Postoperative factors such as complications, pain, recurrence rate, and operative time were compared between the 2 groups. Results Total effective rate was 100% in both groups. No long-term chronic pain occurred and discomfort rate of tenesmus was higher in the STARR group than in the TVMR group. Postoperative defecography showed that the rectocele depth was significantly reduced, and the prolapse of the rectal mucosa and the lower rectal capacity was also decreased. Four cases had mesh exposure in the TVMR group and 2 cases in the STARR group had anastomotic bleeding after the surgery. Conclusions For outlet obstruction constipation caused by rectocele, TVMR and STARR both obtained satisfactory results. Although TVMR is complex with longer operative time and hospitalization period, its long-term effect is better than that of STARR. PMID:28146137

    The flood in June 2013 caused in Germany severe damage to infrastructure and has had a great impact on transportation. Traffic was disrupted in the interregional transportation network including federal highways and long distance railways. Researchers from the Center for Disaster Management and Risk Reduction Technology (CEDIM) aim to develop rapid assessment tools which allow a science based estimation of disaster impacts. This is part of a larger project called Forensic Disaster Analysis (FDA). During the flood event, the CEDIM FDA group on transportation disruptions monitored and recorded traffic reports in Germany to obtain accurate information on road traffic obstructions due to the flood. A rapid initial evaluation of the data was carried out for federal and interstate highways on a district level for the period of May 31 till June 4 2013. In this evaluation, the causes and types of traffic obstruction, as well as the number and duration of flood-caused disruptions are considered. In the evaluated time period of five days, an amount of more than 4,800 hours of flood-related traffic obstructions could be observed in a total of 89 districts. Major traffic disruptions were located in the districts along the Mulde and in the foothills of the Alps. This first initial evaluation will be followed by a detailed statistical analysis including all data collected during the flood event. To assess the impacts of the flood on traffic, a simple traffic simulation considering the disruptions will be carried out using a gravity model.

    Three-dimensional (3D) power Doppler sonographic imaging provides a 3D view of the blood vessels. This technique reportedly has advantages over other forms of sonography in visualizing normal and abnormal fetal vascular anatomy. We report the case of a 36-year-old pregnant woman in whom 3D power Doppler sonography with simultaneous gray-scale imaging was performed at 32 weeks' gestational age to investigate an intestinal obstruction in the fetus that was suspected on the basis of 2-dimensional sonographic findings. The 3D sonograms revealed that the superior mesenteric artery and vein of the fetus were wound counterclockwise, forming the "barber-pole" sign. At 38 weeks' menstrual age, the female infant was delivered vaginally. Only duodenal atresia and annular pancreas, but not intestinal malrotation, were found postnatally. Surgical reconstruction of the duodenum was performed, with no major complications. Previous research suggests that the counterclockwise barber-pole sign is a normal finding. On the basis of our case, we believe that this "negative finding" might be used to exclude the diagnosis of midgut volvulus, a condition that would be expected to cause these vessels to wrap around in a clockwise direction.

    Background: Hydrocephalus caused by unilateral foramen of Monro (FM) obstruction has been referred to in literature by many different terminologies. Precise terminology describing hydrocephalus confined to just one lateral ventricle has a very important prognostic value and determines whether or not the patient can be shunt free after an endoscopic procedure. Methods: Aiming to define the best term for unilateral FM obstruction, 19 terms were employed on PubMed database (http://www.ncbi.nlm.nih.gov/pubmed) as quoted phrases. Results: A total of 194 articles were found. Four patterns of hydrocephalus were discriminated as a result of our research term query and were divided by types for didactic purpose. Type A - partial dilation of the lateral ventricle; Type B - pure unilateral obstruction of the FM; Type C - previously shunted patients with secondary obstruction of the FM; and Type D - asymmetric lateral ventricles with patent FM. Conclusion: In unilateral FM obstruction hydrocephalus, an in-depth review on terminology application is critical to avoid mistakes that may compromise comparisons among different series. This terminology review suggests that Type B hydrocephalus, i.e., the hydrocephalus confined to just one lateral ventricle with no other sites of cerebrospinal fluid circulation blockage, are best described by the terms unilateral hydrocephalus (UH) and monoventricular hydrocephalus, the first being by far the most popular. Type A hydrocephalus is best represented in the literature by the terms uniloculated hydrocephalus and loculated ventricle; Type C hydrocephalus by the terms isolated lateral ventricle and isolated UH; and Type D hydrocephalus by the term asymmetric hydrocephalus.

    Urethral obstruction may be caused by prostatic hypertrophy, urethral stricture, or encrustation of a urethral-catheter lumen. Bacteriuria often complicates these obstructions. The sequelae include fever, acute pyelonephritis, chronic renal inflammation, and death. We hypothesized that even brief obstruction of the urinary tract containing a nonvirulent bacterium would result in these complications. Mice challenged transurethrally with Escherichia coli FN414, which is rapidly eliminated from normal mice without causing bacteriuria, bacteremia, or renal pathology, were subjected to reversible urethral obstruction by coating the urethral meatus with collodion for 1, 3, or 6 h. The majority of mice obstructed for 1 h demonstrated parenchymal renal inflammation 48 h later. At the end of 3 h of obstruction, 9 of 10 mice were bacteremic; some bacteremias were present at 48 h after removal of the obstruction. At that time, more severe renal inflammation was seen in these mice. As little as 6 h of obstruction resulted not only in the acute changes described above but also in chronic renal inflammation and fibrosis in the majority of animals sacrificed 3 and 6 weeks later. Additional studies demonstrated that urethral obstruction enhanced the uropathogenicity of another nonpathogenic E. coli strain (K-12 strain HB101) and caused more severe renal lesions in mice challenged with E. coli CFT073, isolated from a patient with symptoms of pyelonephritis. These findings demonstrate that brief urethral obstruction may (i) induce organisms which are cleared rapidly from the normal urinary tract to cause bacteriuria, bacteremia, and pyelonephritis and (ii) intensify the renal lesions caused by a uropathogen.

    Gallstone ileus of the sigmoid colon is an important, though extremely rare, cause of large bowel obstruction. The gallstone often enters the large bowel through a fistula formation between the gallbladder and colon, and impacts at a point of narrowing, causing large bowel obstruction. We describe the case of an 80-year-old woman who presented with features of bowel obstruction. Multiplanar abdominal CT demonstrated a cholecystocolonic fistula in exquisite detail. The scan also showed obstruction of the colon due to a large gallstone impacted just proximal to a stricture in the sigmoid. Owing to inflammatory adhesions and a stricture from extensive diverticular disease, the gallstone could not be retrieved. This frail and elderly woman was treated with a loop colostomy to relieve bowel obstruction. The patient made an uneventful recovery.

    We report on the successful use of fetoscopic surgery to treat a case of prolapsed ureterocele in a female fetus. At 21 weeks' gestation, a double renal system with an intravesical ureterocele obstructing the bladder outlet was diagnosed, causing severe megacystis, bilateral hydronephrosis and progressive oligohydramnios. Ultrasound evaluation following referral to our center confirmed severe bilateral hydronephrosis with pelvic and calyceal dilatation, but amniotic fluid volume was normal and the ureterocele was not visualized in the bladder. Instead, a cystic mass within the external genitalia was observed, suggestive of a prolapsed ureterocele, causing intermittently severe obstruction of the urethra. The parents were counseled about the uncertain prognosis and fetal surgery to decompress the urinary system was proposed. The procedure involved firing a contact diode laser until perforation of the ureterocele was achieved. Following laser surgery, resolution of megacystis, reduction of hydronephrosis and normalization of amniotic fluid volume were observed. Our report demonstrates that fetoscopic decompression of a distal urethral obstruction is feasible in the rare event of congenital prolapsed ureterocele.

    Ascaris Lumbricoides is the most common worm found in human beings and it is the largest of the intestinal nematodes parasitizing humanity. The most common complication of Ascariasis is mechanical bowel obstruction caused by a large number of worms. Bowel obstruction can also be caused by various toxins released by the worms. A large worm bolus can also cause volvulus or intussusception. We report a case of Intestinal Obstruction due to an Ileal MZBCL in an Ascaris. Lumbricoides infestation setting.

    Necropsy examination of dolphins living in Gulf St Vincent, Australia is routinely undertaken to enable the evaluation of disease processes and to provide rapid medicolegal assessment of any inflicted and/or accidental injuries. Two Indo-Pacific Bottlenose Dolphins (Tursiops aduncus) are reported to demonstrate conditions that may result in unexpected death involving upper airway compromise by quite unusual mechanisms. In the first case an adult male was found with extensive soft tissue trauma suggesting human interaction. At necropsy, death was due instead to upper airway obstruction from an impacted Slender-spined Porcupine Fish (Diodon nichthemerus) in the posterior pharynx and upper esophagus. In the second case, an adult male dolphin was found to have died, following several weeks' illness, from upper airway obstruction due to extensive respiratory tract papillomatosis within the blowhole. Given the infectious etiology of this condition the local population will be monitored for similar lesions. These cases demonstrate rare causes of upper airway obstruction in wild dolphins that were identifiable only after detailed necropsy examination. The possibility of human involvement in the deaths could be excluded.

    Anisakiasis and endometriosis is rare cause of intestinal obstruction and even perforation, the latter being extremely rare. We report the case of a patient with intestinal obstruction that progress to perforation and whose differential diagnosis is complex. The interest in this clinical case lies in the unexpected histology of the surgical specimen after the intervention of the patient, because the intestinal endometriosis as intestinal anisakiasis are rare entities that make diagnosis difficult.

    A 7-year-old male trotter horse with a history of recurrent colic displayed clinical findings consistent with chronic intestinal pseudo-obstruction (CIP). At laparotomy, an impaction of the descending colon associated with marked atrophy of the right dorsal colon was found. The horse was humanely destroyed and tissues collected at necropsy examination revealed diffuse enteric ganglionitis comprising an infiltrate of CD3(+) T lymphocytes and plasma cells. At all levels of the intestinal tract the number of myenteric ganglia and of normal ganglion cells was decreased significantly. There were chromatolytic or necrotic neurons and the amount of connective tissue surrounding ganglia was increased. Immunohistochemical studies demonstrated slightly reduced expression of neuron-specific enolase and a moderate increase in expression of S100 and glial fibrillary acidic protein in a sample of right dorsal colon taken during the necropsy examination compared with a biopsy sample taken from the same location. Immunolabelling and semi-nested polymerase chain reaction for equine herpesvirus (EHV)-1 performed on the gut were positive, supporting an aetiological relationship between EHV-1 infection and the enteric ganglionitis.

    Ascaris lumbricoides infection affects approximately 1.5 billion people globally. Children with environmental and socio-economic risk factors are more susceptible to infestation, with serious complications such as intestinal obstruction (IO), volvulus, intussusception, and intestinal necrosis.We present the case of a 3-year-old girl who arrived at emergency department with abdominal pain and diarrhea for the last 3 days. The previous day she took an unspecified anthelmintic. Symptoms worsened with vomiting and diarrhea, with expulsion of roundworms through mouth and anus. Physical examination revealed bloating, absence of bowel sounds, abdominal tenderness, and a palpable mass in right hemi-abdomen. Abdominal radiographs showed air-fluid levels with mild bowel distention and shadows of roundworms. The diagnosis of IO by A lumbricoides. infestation was established and surgical approach scheduled. During exploratory laparotomy an intraluminal bolus of roundworms from jejunum to ascendant colon was evident. An ileum enterotomy was performed and worms were removed. Fluid therapy and antibiotics for 72  hours were administered, with posterior albendazol treatment for 3 days. Patient was uneventfully discharged on the tenth day.Reduction in parasitic load by means of improvements in sanitation, health education, and anthelmintic treatment must be implemented in endemic zones to prevent serious life-threatening complications by A lumbricoides. infestation, because some of them require urgent surgical treatment.

    The absence of bile in the gut lumen induces mucosal injury and promotes bacterial translocation (BT). Prostaglandin E (PGE) has a protective effect on the mucosal layer of the alimentary tract. We hypothesize that PGE1 may prevent BT by its beneficial action on the mucosa of the small bowel. Thirty Wistar albino rats were divided equally into 3 groups; Group 1 (control) underwent sham laparotomy, group 2 obstructive jaundice (OJ) and group 3 (OJ + PGE1) underwent common bile duct (CBD) ligation and transection. Groups 1 and 2 received; 1 mL normal saline and group 3 received 40 mg of the PGE1 analogue misoprostol dissolved in 1 mL normal saline administered by orogastric tube once daily. After 7 days, laparotomy and collection of samples for laboratory analyses were performed, including bacteriological analysis of intestine, mesenteric lymph nodes (MLNs), and blood, and histopathologic examination of intestinal mucosa to determine mucosal thickness and structural damage. Serum bilirubin and alkaline phosphatase levels confirmed OJ in all animals with CBD transection. The mucosal damage score was significantly reduced in jaundiced animals receiving PGE1 compared to jaundiced controls (2.15 +/- 0.74 vs 5.3 +/- 0.59; p < .00001) and mucosal thickness was greater (607 +/- 59.1 microm vs. 393 +/- 40.3 microm; p < .00001). The incidence of BT to MLNs decreased from 90% to 30% (p < .02) when jaundiced rats received PGE1. PGE1 treatment reduced the detection rate of viable enteric bacteria in the blood from 60% to 10% (p < .057). We conclude that administration of PGE1 provides protection against OJ-induced atrophy and damage of intestinal mucosa, and thereby prevents translocation of enteric bacteria to underlying tissues.

    FEPs are rare, benign mucosal growths that may cause urinary tract obstruction in both adults and children. We present the case of a ten year old Hispanic male with recurring urinary tract infections and hydronephrosis diagnosed with fibroepithelial polyps (FEPs). Despite multiple radiographic procedures, we were unable to accurately preoperatively diagnose FEPs. Here we demonstrate the difficulties in preoperative diagnosis and suggest that perhaps a combination of US and MRI in the setting of persistent urinary tract infections and flank pain may be the best approach for early diagnosis and conservative management, including less invasive treatment protocols.

    We report 3 cases with unusual complications of gastric outlet obstruction caused by a gastrostomy tube balloon. All cases developed vomiting, and 2 cases were accompanied by hematemesis. Gastric ulcer was observed in 1 case, aspiration pneumonia was observed in 2 cases, and pancreatitis was observed in 1 case. This condition improved rapidly by correction of the position of the balloon in all cases. In patient vomiting during management for gastrostomy we need to consider migration of the gastrostomy tube balloon. Careful management of the gastrostomy tube balloon is important.

    Most patients with thymic cysts complain of a slowly enlarging, asymptomatic cervical mass. Only 6-10% suffer dysphagia, dyspnoea, stridor, cervical pain or vocal paralysis. In some rare cases sudden onset of severe dyspnoea or asphyxia is the first symptom, especially in neonates and small infants. We report a unique case of a 20-month-old child, who required emergency tracheal intubation due to asphyxia. Cervicomediastinal thymic cyst might need to be included in causes of life-threatening airway obstruction in young children.

    Irritable bowel syndrome (IBS) is a heterogeneous functional disorder with a multifactorial etiology that involves the interplay of both host and environmental factors. Among environmental factors relevant for IBS etiology, the diet stands out given that the majority of IBS patients report their symptoms to be triggered by meals or specific foods. The diet provides substrates for microbial fermentation, and, as the composition of the intestinal microbiota is disturbed in IBS patients, the link between diet, microbiota composition, and microbial fermentation products might have an essential role in IBS etiology. In this review, we summarize current evidence regarding the impact of diet and the intestinal microbiota on IBS symptoms, as well as the reported interactions between diet and the microbiota composition. On the basis of the existing data, we suggest pathways (mechanisms) by which diet components, via the microbial fermentation, could trigger IBS symptoms. Finally, this review provides recommendations for future studies that would enable elucidation of the role of diet and microbiota and how these factors may be (inter)related in the pathophysiology of IBS.

    Although Bacillus cereus is a ubiquitous bacterium, the incidence of neonatal infections is very low with only a few cases of B. cereus infections in neonates reported in the literature. We report the case of a premature infant with multiple intestinal perforations and an abdominal B. cereus infection. The initial course was characterized by severe cardiovascular shock, anemia, thrombocytopenia and disseminated intravascular coagulation, leading to periventricular leukomalacia, alopecia capitis and toxic epidermal necrolysis. The possible role of B. cereus-associated enterotoxins for the clinical manifestations are discussed. Our case confirms previous reports of severe clinical symptoms in B. cereus infection in premature neonates. We speculate that the systemic complications of B. cereus infection are at least partly related to the effect of B. cereus-associated enterotoxins.

    The iliac crest has become an often used site for autogenous bone graft, because of the easy access it affords. One of the less common complications that can occur after removal is a graft-site hernia. It was first reported in 1945 (see the work by Oldfield, 1945). We report a case of iliac crest bone hernia in a 53-year-old male who was admitted for elective resection of a pseudarthrosis and reconstruction of the left femur with iliac crest bone from the right side. One and a half months after initial surgery, the patient presented with increasing abdominal pain and signs of bowel obstruction. A CT scan of the abdominal cavity showed an obstruction of the small bowel caused by the bone defect of the right iliac crest. A laparoscopy showed a herniation of the small bowel. Due to collateral vessels of the peritoneum caused by portal hypertension, an IPOM (intraperitoneal onlay-mesh) occlusion could not be performed. We performed a conventional ventral hernia repair with an onlay mesh. The recovery was uneventful. PMID:22084778

    Obstructive hydrocephalus caused by tectal glioma, which relived by neuroendoscopy, have been described using 3.0 Tesla magnetic resonance imaging (3T MRI) so far, we present the results obtained from 3T and 7T MRI in this patient. A 21-year-old woman presented at our hospital with gait disturbance, hormonal insufficiency, and urinary incontinence that began prior to 6 years of age. 3.0T MRI revealed a non-enhancing tectal mass along with obstructive hydrocephalus. The mass measured approximately 1.1×1.0×1.2 cm. An endoscopic third ventriculostomy was performed to relieve the hydrocephalus. We compared hydrocephalus and cerebrospinal fluid (CSF) flow findings from 3T and 7T MRI, both preoperative and postoperative at 1, 6 months. Intraventricular CSF voiding on T2-weighted images obtained with 7T MRI showed greater fluid inversion than those obtained with 3T MRI. This study shows that 7T brain MRI can provide detailed information on hydrocephalus caused by tectal glioma. Further studies are needed to develop refined 7T MRI protocols for better images of hydrocephalus. PMID:27867929

    Dai-kenchu-to (DKT), a traditional Japanese herbal medicine (Kampo medicine), composed of zanthoxylum fruit, ginseng root, dried ginger rhizome and malt sugar, is clinically effective for postoperative ileus and chronic constipation. MMIHS and CIIP are severe motility disorder associated with high morbidity. The aim of this study was to evaluate the effect of DKT on functional intestinal obstruction. DKT was clinically effective for gastrointestinal motility in a case with MMIHS, but not effective in one with CIIP. MMIHS and CIIP are speculated to have different pathogenesis regarding gastrointestinal pseudo-obstruction based upon the effect of this drug.

    The relation of ventilatory impairment and chronic mucus hypersecretion to death from all causes and death from obstructive lung disease (chronic bronchitis, emphysema and asthma) was studied in 13,756 men and women randomly selected from the general population of the City of Copenhagen. During the 10 year follow up 2288 subjects died. In 164 subjects obstructive lung disease was considered to be an underlying or a contributory cause of death (obstructive lung disease related death); in 73 subjects it was considered to be the underlying cause of death (obstructive lung disease death). Forced expiratory volume in one second, expressed as a percentage of the predicted value (FEV1% pred), and the presence of chronic phlegm were used to characterise ventilatory function and chronic mucus hypersecretion respectively. For mortality analysis the proportional hazards regression model of Cox was used; it included age, sex, pack years, inhalation habit, body mass index, alcohol consumption, and the presence or absence of asthma, heart disease, and diabetes mellitus as confounding factors. By comparison with subjects with an FEV1 of 80% pred or more, subjects with an FEV1 below 40% pred had increased risk of dying from all causes (relative risk (RR) = 5.0 for women, 2.7 for men), a higher risk of obstructive lung disease related death (RR = 57 for women, 34 for men), and a higher risk of obstructive lung disease death (RR = 101 for women, 77 for men). Chronic mucus hypersecretion was associated with only a slightly higher risk of death from all causes (RR = 1.1 for women, 1.3 for men). The association between chronic mucus hypersecretion and obstructive lung disease death varied with the level of ventilatory function, being weak in subjects with normal ventilatory function (for an FEV1 of 80% pred the RR was 1.2), but more pronounced in subjects with reduced ventilatory function (for an FEV1 of 40% pred the RR was 4.2). A similar though statistically non-significant trend was

    Around 40% of the world's population continue using solid fuel, including wood, for cooking or heating their homes. Chronic exposure to wood smoke is a risk factor for developing chronic obstructive pulmonary disease (COPD). In some regions of the world, this can be a more important cause of COPD than exposure to tobacco smoke from cigarettes. Significant differences between COPD associated with wood smoke (W-COPD) and that caused by smoking (S-COPD) have led some authors to suggest that W-COPD should be considered a new COPD phenotype. We present a review of the differences between W-COPD and S-COPD. On the premise that wood smoke and tobacco smoke are not the same and the physiopathological mechanisms they induce may differ, we have analyzed whether W-COPD can be considered as another COPD phenotype or a distinct nosological entity.

    A case is presented of intestinal schistosomiasis due to both Schistosoma intercalatum and Schistosoma mansoni in a 30-year-old man from Senegal with discussion of diagnostic approach, species identification and determination of the effect of treatment. The patient was admitted to hospital for investigation of renal failure, arterial hypertension and hypereosinophilia. Repeated stool examinations for ova and parasites were negative. Ultrasonography (US) and computed tomography (CT) of the abdomen showed no abnormalities. US of the urinary tract showed kidneys of borderline size with increased echogenicity. Cystoscopy and histopathological examination of bladder biopsy specimens were normal. Flexible colonoscopy revealed numerous nodular lesions in the rectosigmoid region and a few similar lesions in the transverse colon, the histopathological examination of which showed deposition of Schistosoma ova with granuloma formation. Examination of multiple crush biopsy specimens from the rectosigmoid region revealed numerous granulomas formed around Schistosoma eggs which had a terminal spine and were identified as S. intercalatum (longer than Schistosoma haematobium and with a slightly curved terminal spine) and a very few S. mansoni eggs. Crush biopsies from the lesions in the transverse colon showed only S. mansoni eggs. In conclusion, the examination of multiple crush biopsy specimens is a very sensitive and specific technique for species identification of Schistosoma, especially in mixed infections, and for defining the location and extent of the granulomas evoked by each species.

    A young female had neurofibromatosis, annular pancreas and heterotopic pancreas, a combination not previously described. The tumour caused bleeding and intussusception of the distal part of the small intestine. An extensive range of examinations was initiated; however, the diagnosis was not clarified until explorative laparoscopy was performed. Heterotopic pancreas is worth considering as an infrequent cause of gastrointestinal bleeding and invagination.

    A 55-year-old woman with a history of bowel dysmotility presented with abdominal distension and peritonitis. Family history included premature deaths with intestinal symptomatology, suggesting autosomal dominant inheritance. Computed tomography showed a distended small bowel. Symptoms were alleviated by enterocutaneous stomas. Initial ileal biopsy suggested neuropathy; however, exome sequencing revealed an Arg148Ser mutation in the enteric smooth muscle actin gamma 2 (ACTG2) gene. Histological reassessment showed abnormal muscularis propria and smooth muscle actin, with the same findings in sibling, confirming familial visceral myopathy. Thus, noninvasive genomic analysis can provide early and specific diagnosis of familial visceral myopathy, which may help to avoid inappropriate surgery.

    A 24-year-old female patient presented to our community emergency department (ED) for abdominal pain that had progressively worsened over the last 28 hours. Of note, 1 month prior to her presentation, the patient had a colostomy due to a rectal abscess and required stoma revision 5 days prior to her visit to our ED. The patient's pain was refractory to opiate analgesia in our ED, but experienced significant relief after an intravenous lidocaine infusion. Computer tomography of the abdomen and pelvis ultimately revealed a large bowel obstruction just proximal to the colostomy site. Historically, options for ED management of severe pain have been limited beyond narcotic analgesia. For patients whom are refractory to opiates in the ED, or for whom opiates are contraindicated, lidocaine infusions have shown promise for a variety of both acute and chronic painful conditions.

    Intestinal permeability (IP) to /sup 51/Cr ethylenediamine tetraacetic acid was investigated in 47 children with chronic obstructive respiratory disease (CORD). Endoscopic duodenal biopsies were performed in 22 of these patients. IP was significantly increased in CORD patients when compared to either control children or adults (P less than 0.001). Mean +/- 1 SD were 4.3 +/- 1.71%, 2.5 +/- 0.78%, and 2.3 +/- 0.77% in the three groups, respectively. IP was not related to the presence of atopy. Significant differences in IP results were found between CORD children with abdominal pain (4.5 +/- 1.4%) and both control children and CORD patients without abdominal pain (2.5 +/- 0.78% and 3.2 +/- 1.49%, respectively). A significant correlation was found between small bowel injury on the one hand and IP on the other hand (P less than 0.02). Furthermore, small bowel injury was significantly related to the presence of abdominal pain (P less than 0.05). We speculate that in CORD patients with abdominal pain, a factor exists that causes small bowel injury responsible for both abdominal pain and increased small bowel permeability. Food intolerance could, presumably, play a role in the mucosal damage-linked IP increase found in the subset of CORD patients who complain of abdominal pain.

  16. Induction of periodic breathing during sleep causes upper airway obstruction in humans.

    1986-10-01

    To test the hypothesis that occlusive apneas result from sleep-induced periodic breathing in association with some degree of upper airway compromise, periodic breathing was induced during non-rapid-eye-movement (NREM) sleep by administering hypoxic gas mixtures with and without applied external inspiratory resistance (9 cmH2O X l-1 X s) in five normal male volunteers. In addition to standard polysomnography for sleep staging and respiratory pattern monitoring, esophageal pressure, tidal volume (VT), and airflow were measured via an esophageal catheter and pneumotachograph, respectively, with the latter attached to a tight-fitting face mask, allowing calculation of total pulmonary system resistance (Rp). During stage I/II NREM sleep minimal period breathing was evident in two of the subjects; however, in four subjects during hypoxia and/or relief from hypoxia, with and without added resistance, pronounced periodic breathing developed with waxing and waning of VT, sometimes with apneic phases. Resistive loading without hypoxia did not cause periodicity. At the nadir of periodic changes in VT, Rp was usually at its highest and there was a significant linear relationship between Rp and 1/VT, indicating the development of obstructive hypopneas. In one subject without added resistance and in the same subject and in another during resistive loading, upper airway obstruction at the nadir of the periodic fluctuations in VT was observed. We conclude that periodic breathing resulting in periodic diminution of upper airway muscle activity is associated with increased upper airway resistance that predisposes upper airways to collapse.

    The pathogenesis of the prune belly syndrome (PBS) remains controversial, but two theories predominate. The first theory supports an obstructive phenomenon early in gestation leading to irreversible damage to the genitourinary tract and abdominal wall. The second theory suggests mesodermal injury between the 6th and 10th weeks of gestation as the primary abnormality. This paper reports of two fetuses with the PBS phenotype that were examined postmortem at our institution. Thorough examination of the lower urinary tract allowed demonstration of anatomic obstruction of the urethra in both cases. One case illustrated a relatively common pattern of proximal penile urethral obstruction, a flap-like obstruction between the prostatic and penile urethra. The other case provided what we believe to be the first description of PBS caused by severe phimosis.

    Effective therapies are limited for patients with parenteral nutrition-dependent short bowel syndrome. We previously showed that intestinal expression of the transcriptional coregulator tetradecanoyl phorbol acetate-induced sequence 7 (tis7) is markedly increased during the adaptive response following massive small bowel resection and tis7 plays a role in normal gut lipid metabolism. Here, we further explore the functional implications of tis7 deletion in intestinal lipid metabolism and the adaptive response following small bowel resection. Intestinal tis7 transgenic (tis7(tg)), tis7(-/-), and wild-type (WT) littermates were subjected to 50% small bowel resection. Mice were fed a control or a high-saturated-fat (42% energy) diet for 21 days. Survival, body weight recovery, lipid absorption, mucosal lipid analysis, and the morphometric adaptive response were analyzed. Quantitative real-time PCR was performed to identify tis7 downstream gene targets. Postresection survival was markedly reduced in high-fat, but not control, diet-fed tis7(-/-) mice. Decreased survival was associated with anastomotic inflammation and intestinal obstruction postresection. High-fat, but not control, diet-fed tis7(-/-) mice had increased intestinal IL-6 expression. Intestinal lipid trafficking was altered in tis7(-/-) compared with WT mice postresection. In contrast, high-fat diet-fed tis7(tg) mice had improved survival postresection compared with WT littermates. High-fat diet feeding in the setting of tis7 deletion resulted in postresection anastomotic inflammation and small bowel obstruction. Tolerance of a calorie-rich, high-fat diet postresection may require tis7 and its target genes. The presence of luminal fat in the setting of tis7 deletion promotes an intestinal inflammatory response postresection.

    Background Gastrointestinal stromal tumours are the most common mesenchymal malignancies of the gastrointestinal (GI) tract and gastric leiomyosarcoma represent 1-3% of gastric malignancies. Case presentation We report a case of a 69-year- old black African man who presented with a rare cause of gastric outlet obstruction and duodenal perforation. A Billroth- II gastrectomy was performed and histology confirmed a gastric leiomyosarcoma. Conclusions It is important to identify the gastric leiomyosarcoma which is a variant of the more common malignant gastrointestinal stromal tumours as the pathogenesis and management are currently well established. As the facilities for differentiating these are not easily available in resource-limited areas gastrointestinal stromal tumours may remain underdiagnosed and undertreated. PMID:25069607

    Primary or secondary nasal tuberculosis is rare and usually, it is considered as an extra pulmonary form of tuberculosis. Nasal tuberculosis infection may spread to maxillary palatal region by contagious or haematogenous route causing palatal perforation. In some instance, it may cause septal perforation with nasal obstruction which may give rise to halitosis. We report a case where, there was bilateral nasal mucosal involvement leading to severe nasal obstruction. This rare manifestation should be considered in areas where the disease is prevalent as delay in diagnosis and treatment could lead to serious and life threatening complications due to local spread from the nose to the para nasal sinuses and brain.

    The authors present three cases of death in children aged 4, 9, and 10 years, respectively, that were first thought to be caused by herbal or other poisonings but at autopsy were found to be caused by airway obstruction from aspiration of ballpoint pen parts. Aspiration of a foreign body is a leading cause of accidental death in children, but the circumstances in these cases were unique. In the first case, a 4-year-old child died shortly after a visit to a traditional healer. The child's mother blamed him for the death and fatally assaulted him. The second case was a 9-year-old who died at school. Case 3 was a 10-year-old who collapsed while playing with a ballpoint pen in her mouth. In the latter two cases, the relatives alleged poisoning. At autopsy, there was no evidence of trauma, disease, or poisoning in all three cases. Ballpoint pen parts were present in the larynx, carina, and left main bronchus, respectively. Features of "asphyxial" death were present, and included subconjunctival hemorrhages, subendocardial hemorrhages, and congestion of the face and internal organs. These deaths are preventable by education of children, parents, and teachers. Ballpoint pen manufacturers should also modify the design of these pens to improve their safety.

    Objective Delayed gastric emptying (DGE) in patients with acute pancreatitis (AP) can be caused by gastroparesis or gastric outlet obstruction, which may occur when pancreatic pseudocyst (PP) or walled-off necrosis (WON) compresses the stomach. The aim of the study was to explore a proper surgical treatment. Methods From June 2010 to June 2013, 25 of 148 patients with AP suffered DGE. Among them, 12 were caused by gastroparesis, 1 was a result of obstruction from a Candida albicans plug, and 12 were gastric outlet obstruction (GOO) compressed by PP (n = 8) or WON (n = 4), which were treated by percutaneous catheter drainage (PCD). Results All 12 cases of compressing GOO achieved resolution by PCD after 6 [1.86] and 37.25 [12.02] days for PP and WON, respectively. Five cases developed intracystic infection, 3 cases had pancreatic fistulae whereas 2 achieved resolution and 1 underwent a pseudocyst jejunostomy. Conclusions Gastric outlet obstruction caused by a PP or WON is a major cause of DGE in patients with AP. Percutaneous catheter drainage with multiple sites, large-bore tubing, and lavage may be a good therapy due to high safety and minimal invasiveness. PMID:26465954

    Maternally inherited diabetes and deafness (MIDD) has been related to an A to G transition in the mitochondrial tRNA Leu (UUR) gene at the base pair 3243. This subtype of diabetes is characterized by maternal transmission, young age at onset and bilateral hearing impairment. Besides diabetes and deafness, the main diagnostic features, a wide range of multisystemic symptoms may be associated with the A3243G mutation. Organs that are most metabolically active, such as muscles, myocardium, retina, cochlea, kidney and brain are frequently affected. Gastrointestinal tract symptoms are also common in patients with mitochondrial disease and constipation and diarrhea are the most frequent manifestations. However, there are few prior reports of intestinal pseudo obstruction in MIDD patients. Here we report the case of a patient with MIDD associated with the mtDNA A3243G mutation who developed chronic intestinal pseudo obstruction, and the introduction of Coenzyme Q10 as adjunctive therapy led to a solution of the pseudo obstruction.

    The authors studied the rate of relief in cases of moderate, reversible airway obstruction after Furosemide administration. They examined 25 patients with bronchial asthma and chronic obstructive bronchitis (mean age 49 years). They found out that intravenous administration of Furosemide to patients with chronic obstructive bronchitis has a significant bronchodilating effect. The reduction of interstitial lung water and the decrease in congestion of airways mucosa in latent left ventricular failure may be the possible explanations of this phenomenon. After administration of Furosemide by inhalation, a mild decrease in airway obstruction was observed in asthmatic patients. The influence of Na+/K+/Cl- transport in the bronchial epithelium, or changes in PGE2 are supposed to represent the effective mechanisms. The authors conclude that Furosemide given intravenously to patients with moderate airflow limitation in connection with lung function tests may be helpful in the diagnosis of the nature of airway obstruction.

    Obstructive sleep apnea syndrome is a chronic disease characterized by repeated upper airway obstructions during sleep, resulting in fragmented sleep with arousals, nocturnal intermittent hypoxemia and diurnal dysfunctions. Despite its high prevalence in elderly, sleep apnea syndrome seems to be underestimated and difficult to be recognized because of the lack of clinical symptoms specificity in this population. Among the numerous consequences of the obstructive sleep apnea syndrome, cognitive impairment prevails on the attention, executive functions and memory. Neuroimaging studies in human and experimental models allowed to highlight neural correlates of these cognitive dysfunctions in obstructive sleep apnea syndrome. The obstructive sleep apnea syndrome with cognitive impairment shares some features with Alzheimer's disease, involving genetic predisposition ApoE4, hippocampus and synaptic plasticity abnormalities. In this context, the question arises whether obstructive sleep apnea syndrome is a possible etiological or aggravating factor of cognitive decline in elderly with mild cognitive impairment or Alzheimer's disease. Although there are conflicting results in studies evaluating therapeutic efficiency of continuous positive air pressure, obstructive sleep apnea syndrome seems nevertheless as a correctable factor, at least for its impact on some cognitive consequences. Looking for sleep apnea syndrome in elderly with cognitive decline should be considered in a global, diagnosis and therapeutic management.

    2015-01-01

    Respiratory and/or limb muscle dysfunction, which are frequently observed in chronic obstructive pulmonary disease (COPD) patients, contribute to their disease prognosis irrespective of the lung function. Muscle dysfunction is caused by the interaction of local and systemic factors. The key deleterious etiologic factors are pulmonary hyperinflation for the respiratory muscles and deconditioning secondary to reduced physical activity for limb muscles. Nonetheless, cigarette smoke, systemic inflammation, nutritional abnormalities, exercise, exacerbations, anabolic insufficiency, drugs and comorbidities also seem to play a relevant role. All these factors modify the phenotype of the muscles, through the induction of several biological phenomena in patients with COPD. While respiratory muscles improve their aerobic phenotype (percentage of oxidative fibers, capillarization, mitochondrial density, enzyme activity in the aerobic pathways, etc.), limb muscles exhibit the opposite phenotype. In addition, both muscle groups show oxidative stress, signs of damage and epigenetic changes. However, fiber atrophy, increased number of inflammatory cells, altered regenerative capacity; signs of apoptosis and autophagy, and an imbalance between protein synthesis and breakdown are rather characteristic features of the limb muscles, mostly in patients with reduced body weight. Despite that significant progress has been achieved in the last decades, full elucidation of the specific roles of the target biological mechanisms involved in COPD muscle dysfunction is still required. Such an achievement will be crucial to adequately tackle with this relevant clinical problem of COPD patients in the near-future. PMID:26623119

    The association between nocturnal apneas and transient pulmonary hypertension (PHT) has been well documented. However, there is controversy over the frequency and pathophysiological mechanisms of daytime pulmonary hypertension in patients with obstructive sleep apnea (OSAS). The present study sought to evaluate frequency and mechanisms of pulmonary hypertension in patients with OSAS. It included 49 consecutive patients with polysomnographically proven OSAS without pathological lung function testing. All patients performed daytime measurements of pulmonary hemodynamics at rest and during exercise (50-75W). Six patients (12%) had resting PHT mean pulmonary of artery pressure (PAPM) of >20 mmHg), whereas 39 patients (80%) showed PHT during exercise (PAPM >30 mmHg). Multiple regression analysis revealed 3 independent contributing factors for mean pulmonary artery pressure during exercise (PAPMmax): body mass index, age and total lung capacity % of predicted. Twenty-five of the 39 patients with pathologically high PAPMmax (64%) showed elevated pulmonary capillary wedge pressures (PCWPmax > 20 mmHg), whereas no patient had elevated pulmonary vascular resistance (PVRmax > 120 dynes x s x cm(-5)). In conclusion, daytime PHT during exercise is frequently seen in patients with OSAS and normal lung function testing and is mainly caused by abnormally high PCWP, whereas PVR seems to play a minor role.

    In 30 rabbits, separated into 3 groups (A, B and C), the entire area (A), three quarters (B) half of the anterior chamber angle (C) was experimentally obstructed by means of a homologous scleral graft. In groups A and B a statistically significant change of the intraocular pressure and of the cornea diameter was shown as compared with the control eye and group C. This change is due to the obstructed area of the angle. The increased intraocular pressure lasted for some months. The graft was well tolerated by the tissue of the angle and the obstruction of the angle was total, as was confirmed by means of the histological preparations.

    It is widely recognized that the intestinal microbiota plays a role in the initiation and perpetuation of intestinal inflammation in numerous chronic conditions. Most studies report intestinal dysbiosis in celiac disease (CD) patients, untreated and treated with a gluten-free diet (GFD), compared to healthy controls. CD patients with gastrointestinal symptoms are also known to have a different microbiota compared to patients with dermatitis herpetiformis and controls, suggesting that the microbiota is involved in disease manifestation. Furthermore, a dysbiotic microbiota seems to be associated with persistent gastrointestinal symptoms in treated CD patients, suggesting its pathogenic implication in these particular cases. GFD per se influences gut microbiota composition, and thus constitutes an inevitable confounding factor in studies conducted in CD patients. To improve our understanding of whether intestinal dysbiosis is the cause or consequence of disease, prospective studies in healthy infants at family risk of CD are underway. These studies have revealed that the CD host genotype selects for the early colonizers of the infant's gut, which together with environmental factors (e.g., breast-feeding, antibiotics, etc.) could influence the development of oral tolerance to gluten. Indeed, some CD genes and/or their altered expression play a role in bacterial colonization and sensing. In turn, intestinal dysbiosis could promote an abnormal response to gluten or other environmental CD-promoting factors (e.g., infections) in predisposed individuals. Here, we review the current knowledge of host-microbe interactions and how host genetics/epigenetics and environmental factors shape gut microbiota and may influence disease risk. We also summarize the current knowledge about the potential mechanisms of action of the intestinal microbiota and specific components that affect CD pathogenesis.

    The main aim of the study was to prove the compensative effect of intestine for renal function. Rat kidney was impaired by intragastrically administrating adenine (400 mg per day for 5 days). Intestinal tract was harvested and equally divided into 20 segments except cecum. Kidneys were harvested and histologically examined with hematoxylin-eosin staining kits. Uric acid, urea (BUN), and creatinine in serum were determined with assay kits, and BUN and creatinine in every intestinal segment were also determined. The results showed that adenine was able to increase uric acid level in serum from 20.98 ± 6.98 μg/mL to 40.77 ± 7.52 μg/mL and cause renal function damage with BUN (from 3.87 ± 0.62 mM to 12.33 ± 3.27 mM) and creatinine (from 51.48 ± 6.98 μM to 118.25 ± 28.63 μM) increasing in serum and with abnormally micromorphological changes in kidney. The amount of BUN and creatinine distributed in intestinal tract was positively correlated with those in blood. In impaired renal function rats, the amount of BUN (from 4.26 ± 0.21 μMole to 10.72 ± 0.55 μMole) and creatinine (from 681.4 ± 23.3 nMole to 928.7 ± 21.3 nMole) distributed in intestinal tract significantly increased. All the results proved that intestinal tract had excretory function compensative for renal function. PMID:27975080

    We recently reported that levels of unsaturated lysophosphatidic acid (LPA) in the small intestine significantly correlated with the extent of aortic atherosclerosis in LDL receptor-null (LDLR⁻/⁻) mice fed a Western diet (WD). Here we demonstrate that WD increases unsaturated (but not saturated) LPA levels in the small intestine of LDLR⁻/⁻ mice and causes changes in small intestine gene expression. Confirmation of microarray analysis by quantitative RT-PCR showed that adding transgenic tomatoes expressing the apoA-I mimetic peptide 6F (Tg6F) to WD prevented many WD-mediated small intestine changes in gene expression. If instead of feeding WD, unsaturated LPA was added to chow and fed to the mice: i) levels of LPA in the small intestine were similar to those induced by feeding WD; ii) gene expression changes in the small intestine mimicked WD-mediated changes; and iii) changes in plasma serum amyloid A, total cholesterol, triglycerides, HDL-cholesterol levels, and the fast-performance liquid chromatography lipoprotein profile mimicked WD-mediated changes. Adding Tg6F (but not control tomatoes) to LPA-supplemented chow prevented the LPA-induced changes. We conclude that: i) WD-mediated systemic inflammation and dyslipidemia may be in part due to WD-induced increases in small intestine LPA levels; and ii) Tg6F reduces WD-mediated systemic inflammation and dyslipidemia by preventing WD-induced increases in LPA levels in the small intestine.

    Mucin-type O-linked oligosaccharides (O-glycans) are primary components of the intestinal mucins that form the mucus gel layer overlying the gut epithelium. Impaired expression of intestinal O-glycans has been observed in patients with ulcerative colitis (UC), but its role in the etiology of this disease is unknown. Here, we report that mice with intestinal epithelial cell-specific deficiency of core 1-derived O-glycans, the predominant form of O-glycans, developed spontaneous colitis that resembled human UC, including massive myeloid infiltrates and crypt abscesses. The colitis manifested in these mice was also characterized by TNF-producing myeloid infiltrates in colon mucosa in the absence of lymphocytes, supporting an essential role for myeloid cells in colitis initiation. Furthermore, induced deletion of intestinal core 1-derived O-glycans caused spontaneous colitis in adult mice. These data indicate a causal role for the loss of core 1-derived O-glycans in colitis. Finally, we detected a biosynthetic intermediate typically exposed in the absence of core 1 O-glycan, Tn antigen, in the colon epithelium of a subset of UC patients. Somatic mutations in the X-linked gene that encodes core 1 β1,3-galactosyltransferase-specific chaperone 1 (C1GALT1C1, also known as Cosmc), which is essential for core 1 O-glycosylation, were found in Tn-positive epithelia. These data suggest what we believe to be a new molecular mechanism for the pathogenesis of UC.

    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.

    Patient: Male, 67 Final Diagnosis: Lung cancer Symptoms: Short of breath Medication: — Clinical Procedure: Mechanical ventilation Specialty: Critical Care Medicine Objective: Unusual setting of medical care Background: Mechanical ventilation strategies for one lung ventilation (OLV) differ from conventional modalities in that it can adapt to greater degrees of ventilation/perfusion (V/Q) mismatch. We present a case of cancer causing complete unilateral endobronchial obstruction with refractory hypoxia that improved with OLV strategy. Case Report: Our patient was an elderly male, admitted to our intensive care unit (ICU) on mechanical ventilation with worsening hypoxic respiratory failure secondary to lung mass and post-obstructive atelectasis. The patient developed refractory hypoxia on high conventional ventilator settings. Chest x-ray (CXR) showed opacification on left lung with ipsilateral mediastinal shift. Bronchoscopy revealed complete obstruction of the left main stem bronchus by a fungating mass. OLV strategy was then implemented. The patient had improved hypoxia despite unchanged CXR. Conclusions: We propose that ventilating a patient with a complete unilateral endobronchial obstruction is physiologically similar to ventilating a patient with OLV. In such cases, OLV strategies may improve refractory hypoxia by minimizing V/Q mismatch and should be considered. PMID:28126982

    Ohman et al. report increased fecal granins in patients with irritable bowel syndrome (IBS). Several interesting questions arise from their observations. Are the granins a cause of the pathophysiology or phenotype in IBS? Is the elevation of granins specific to IBS? What is the cause of increased fecal granin levels? Can fecal granin levels be used to diagnose IBS? Are increased fecal granins an expression of intestinal or colonic irritation? This paper adds to the body of evidence suggesting there are gastrointestinal disturbances in IBS; understanding these disturbances may provide clues to its pathogenesis and optimize management.

    1988-07-01

    Signs of nasal airway obstruction, ranging from hyponasality, snoring, and inability to blow the nose to cardiorespiratory compromise, have been reported after posterior pharyngeal flap surgery. In some cases the symptoms are severe enough to require take-down or revision of the flap. Polysomnography has been used to document obstruction to nasal airflow and may be a guide in selecting patients for flap revision. This case report points out that in certain patients a particular coexisting anatomic abnormality--the locked-out premaxilla--may predispose patients to this symptom complex. In such patients flap revision may not relieve the symptoms, and careful evaluation of the lateral pharyngeal ports is recommended.

    Acute bowel obstruction due to ingested foreign body (FB) like sharp bone fragment is a rare entity. As preoperative diagnosis was uncertain due to lack of proper history, diagnosis is usually done intraoperatively. Even though it is rare, we should consider it as differential diagnosis in patients with recent dietary history. Herein, we are reporting a 38-year-old man, without any psychiatric illness or previous surgery presenting to emergency department with the features of acute bowel obstruction. CT scan shows high density object in ileum suspicious of foreign body. Patient underwent exploratory laparatomy which reveals dilated small bowel with sharp bony object in ileum, which was retrieved with enterotomy.

    An 11-year-old boy with irreversible intestinal failure secondary to chronic intestinal pseudo-obstruction (CIPO) and intestinal failure-associated liver disease (IFALD) underwent a combined en bloc reduced liver and small bowel transplantation. He was discharged home after 9 weeks on full oral intake without requiring intravenous nutritional or fluid supplementation. The first episode of mild acute rejection, which occurred 18 months after transplantation, was successfully treated with steroids. An episode of rotavirus gastroenteritis led to severe exfoliative rejection of the bowel graft, which was resistant to steroid and Infliximab treatment but responded to OKT3. There was associated Epstein-Barr virus viremia with no evidence of posttransplant lymphoproliferative disease. Another episode of moderate to severe acute liver rejection occurred 5 months later. At the same time, multiple biliary strictures were diagnosed and treated. Persistent clinical symptoms of abdominal pain and increased stomal output as well as atrophy of the ileal mucosa on several biopsies, suggested the possibility of chronic rejection (CR). A second combined whole liver and small bowel transplant was performed. The diagnosis of CR was confirmed on histology of the explanted graft. The postoperative course was severely complicated and 71 days after the retransplantation, the boy died because of respiratory failure and multiorgan failure. In summary, intestinal transplantation can be successfully performed in children with CIPO, giving them the opportunity to be free from total parenteral nutrition. As survival following intestinal transplantation continues to improve, the problem of CR has become increasingly important and the only treatment available is retransplantation, which is associated with poor outcomes.

    Introduction. A patent urachus is a rare congenital or acquired pathology, which can lead to complications later in life. We describe a case of urachal cystitis as the etiology of small bowel obstruction in an adult without prior intra-abdominal surgery. Case Report. A 64-year-old male presented to the acute care surgery team with a 5-day history of right lower quadrant abdominal pain, distention, nausea, and vomiting. He had a two-month history of urinary retention and his past medical history was significant for benign prostate hyperplasia. On exam, he had evidence of small bowel obstruction. Computed tomography revealed high-grade small bowel obstruction secondary to presumed ruptured appendicitis. In the operating room, an infected urachal cyst was identified with adhesions to the proximal ileum. After lysis of adhesions and resection of the cyst, the patient was subsequently discharged without further issues. Conclusion. Although rare, urachal pathology should be considered in the differential diagnosis when evaluating a patient with small bowel obstruction without prior intraabdominal surgery, hernia, or malignancy.

    This article reports the findings of what it means to live with intestinal failure caused by Crohn disease and how it influences daily life. Ten patients, 7 with an ostomy and 7 on home parenteral nutrition followed up at an outpatient clinic for patients with intestinal failure, were interviewed using a qualitative, phenomenological-hermeneutic method. The analysis of the transcribed data is described thematically and resulted in 3 main themes; (a) struggling to not be controlled by the disease, (b) walking on a thin thread, and (c) being seen as a person, not just as a patient. These themes led to the comprehensive understanding that living with intestinal failure was interpreted as the criticality of maintaining control over one's life and body while maintaining autonomy and not letting the disease conquer life. Life entails a constant struggle with much planning to live as normally as possible and get the most out of life. It was of great importance to be seen as a person and not just as a disease, affirm that life as it is has meaning, there is a state of suffering related to the disease, there are existential issues, and suffering is related to care.

    Laparoscopic inguinal herniorraphy is a commonly performed procedure given the reported decrease in pain and earlier return to activity when compared with the open approach. Moreover, robotic assistance offers the operating surgeon considerable ergonomic advantages, making it an attractive alternative to conventional laparoscopic herniorraphy. Robotic herniorraphy utilizes the transabdominal preperitoneal approach where following repair peritoneal closure is necessary to avoid mesh exposure to the viscera. Self-anchoring sutures are frequently used to this end given the ease of use and knotless application. We present an unusual case of post-operative small bowel obstruction following robotic inguinal hernia repair caused by the self-anchoring suture used for peritoneal closure. This patient presented 3 days post-procedure with symptoms and cross-sectional imaging indicative of small bowel obstruction with a clear transition point. Underwent laparoscopic lysis of a single adhesive band originating from the loose intraperitoneal end of the suture leading to resolution of symptoms.

    Reversible airway obstruction in childhood includes two major groups of patients: those with recurrent wheezing following bronchiolitis in early childhood, and those with allergic asthma, which represents an increasingly large proportion of cases through the school years. Over the last 40 years of the 20th century, allergic asthma has increased in many countries and in relation to several different allergens. Although this increase has differed in magnitude in different countries and also in the social groups most affected, it has had several features in common. The increase generally started between 1960 and 1970, has been progressive since then, and has continued into the 1990s without a defined peak. Among children 5-18 years of age, the increase has predominantly been among allergic individuals. Theories about the causes of the increase in asthma have focused on two scenarios: a) that changes in houses combined with increased time spent indoors have increased exposure to relevant allergens, or b) that changes in diet, antibiotic use, immunizations, and the pattern of infections in childhood have led to a change in immune responsiveness such that a larger section of the population makes T(H)2, rather than T(H)1 responses including IgE antibodies to inhalant allergens. There are, however, problems with each of these theories and, in particular, none of the proposed changes can explain the progressive nature of the increase over 40 years. The fact that the change in asthma has much in common with epidemic increase in diseases such as Type II diabetes or obesity suggests that similar factors could be involved. Several lines of evidence are reviewed that suggest that the decline in physical activity of children, particularly those living in poverty in the United States, could have contributed to the rise in asthma. The hypothesis would be that the progressive loss of a lung-specific protective effect against wheezing has allowed allergic children to develop

    Ascaris infestation in the gastrointestinal tract is well known in Asian countries. It can be asymptomatic or can present with symptoms of acute abdomen. Perforation and torsion with gangrene are its very rare fatal complications but an important cause of mortality in children. Although ascariasis is very rare in developed countries, clinicians should consider this potentially dangerous, yet treatable, infection in the differential diagnosis of acute abdomen. We herein report a series of five cases of intestinal gangrene secondary to extensive infestation by Ascaris lumbricoides in children aged 1-4 years.

    Radiofrequency procedures are a well-accepted treatment for nasal obstruction. We conducted a randomized, noncontrolled study to compare the effectiveness of submucosal bipolar radiofrequency turbinate volume reduction (RFTVR) and bipolar radiofrequency-assisted turbinectomy (RFaT) in patients presenting with nasal obstruction caused by inferior turbinate hypertrophy. A total of 30 patients-15 males and 15 females, aged 15 to 60 years (mean: 32)-were randomly divided into one of the two homogeneous treatment groups. Outcomes were determined by comparisons of subjective symptom scores on a visual analog scale and by anterior active rhinomanometry at postoperative days 7, 14, and 28 and again at 6 months postoperatively. Both groups demonstrated significant and similar improvements in nasal airway function both subjectively and objectively. However, we noted that the incidence of adverse effects and postoperative morbidity was higher in the RFaT group. Therefore, we conclude that when surgery is indicated, RFTVR is the preferred treatment for nasal obstruction secondary to inferior turbinate hypertrophy. RFaT is equally effective, but it is associated with a slightly higher incidence of adverse effects.

  14. Large ovarian cystadenofibroma causing large bowel obstruction in a patient with Klippel–Feil syndrome—A case report

    2016-01-01

    Introduction Ovarian cystadenofibromas (CAF) are epithelial tumors, which are fairly rare, mainly benign and asymptomatic. The Klippel–Feil syndrome (KFS) is a rare congenital anomaly which combines osseous and visceral development disorders. While bowel obstruction is a common complication in advanced ovarian cancer this condition is rarely described in cystic lesions such as CAF. We report the first case of large bowel obstruction due to a large benign ovarian CAF with an underlying KFS. Presentation of case A 60-year-old women with a KFS was admitted to the hospital with increasing abdominal girth and bowel obstruction. A CT scan revealed a massive intraabdominal cystic tumor of unclear origin, causing compression of the sigmoid colon with consecutive dilatation of the ascending colon and the small bowel. After successful conservative ileus treatment including nasogastric tube and iv fluids for a few days, we performed an explorative laparotomy, revealing a large cystic tumor originating from the left adnexe. After its removal including left adnexectomy, histological findings confirmed a benign cystadenofibroma. The hospital stay was uneventful and bowel obstruction symptoms resolved immediately. Discussion Beside careful history taking and physical examination, diagnostic imaging is important to identify CAF. However, the distinction between benign and malignant lesions remains difficult even using MRI. Considering optimal preparation of the patient with successful ileus treatment, laparoscopy may have been the surgical approach of choice. Though, direct laparotomy seemed to be the appropriate approach, considering the unclear origin and dignity of the lesion. Considering the KFS and its inherent malformations interdisciplinary cooperation seems important in such rare cases. Conclusion Preoperative MR imaging and intraoperative frozen-sections can be helpful to determine the dignity of the neoplasm and avoid fertility impairing adnexectomy in young woman

    CASE DESCRIPTION A 13-year-old female green iguana (Iguana iguana) was examined because of a 6-day history of vomiting, anorexia, and lethargy and a 4-day history of decreased fecal and urate output. CLINICAL FINDINGS Physical examination revealed a distended abdomen, signs of depression, pallor, tachycardia, harsh lung sounds, and vomiting. Abdominal radiographs revealed gas distention of the stomach and small intestine with fluid lines evident on the lateral view. Plasma biochemical analysis indicated hypochloremic metabolic alkalosis, hyperglycemia, and hyperuricemia. TREATMENT AND OUTCOME Exploratory laparotomy confirmed a diagnosis of small intestinal entrapment and 170° volvulus involving approximately 80% (20 to 30 cm) of the small intestine. The portion of the small intestine extending from the middle portion of the duodenum to the caudal extent of the ileum was resected, and end-to-end anastomosis of the remaining small intestine was performed. The iguana recovered without apparent complications and was reportedly doing well 1 year after surgery. CLINICAL RELEVANCE Findings suggested that iguanas, as hindgut fermenters, may tolerate > 70% resection of the small intestine with a good outcome and no clinical evidence of residual gastrointestinal dysfunction.

During this time, she experienced deficiencies of copper, zinc, vitamin A, vitamin B12, folic acid, and biotin, and an excess of vitamin A; she exhibited a series of signs and symptoms due to these deficiencies and vitamin A overdosage. Nevertheless, careful monitoring of serum levels of trace elements and vitamins and appropriate therapy have almost solved these problems. She has achieved normal physical and mental development and goes to school, while receiving home parenteral nutrition with an ambulatory infusion system.

CCE usually occurs during vascular manipulation, such as vascular surgery or endovascular catheter manipulation, or due to anticoagulation or thrombolytic therapy. We report a rare case of intestinal obstruction caused by spontaneous CCE. An 81-year-old man with a history of hypertension was admitted for complaints of abdominal pain, bloating, and anorexia persisting for 4 mo. An abdominal computed tomography revealed intestinal ileus. His symptoms were immediately relieved by an ileus tube insertion, and he was discharged 6 d later. However, these symptoms immediately reappeared and persisted, and partial resection of the small intestine was performed. A histopathological examination indicated that small intestine obstruction was caused by CCE. At the 12-mo follow-up, the patient showed no evidence of CCE recurrence. Thus, in cases of intestinal obstruction, CCE should also be considered.

    The effects of methotrexate on 5-hydroxytryptamine (5-HT) metabolism in the intestinal tissue of rats were investigated during the delayed phase after a single administration. Rats were i.p. injected with methotrexate or with saline as a control, and kaolin and food intakes were measured by an automatic monitoring apparatus. At 96 h after administration, dissected-out ileal tissue was frozen rapidly in liquid nitrogen for further analysis or fixed for immunohistochemical staining. Methotrexate at a dose of 50 mg/kg caused a time-dependent increase in kaolin intake lasting up to 72 h after administration, which returned to the control level at 96 h after administration. This dose of methotrexate caused a gradual decrease in body weight, food intake, and water intake lasting up to 72 h, which approached the control level at 96 h. Methotrexate caused pathologic changes, including a moderate inflammatory response in the ileal tissue and an increase in the number of L-tryptophan hydroxylase (TPH)-expressing cells in the ileal mucosa. Methotrexate also caused a significant increase in 5-HT and 5-hydroxyindoleacetic acid (5-HIAA) content and in TPH1 mRNA expression in the ileal tissues. It had no significant effects on mRNA expression of serotonin transporter, COX-1, or COX-2 or on myeloperoxidase activity. This study demonstrated, for the first time, that methotrexate caused a change in the ileal 5-HT metabolism associated with hyperplasia of mucosal enterochromaffin cells.

    Ascaris lumbricoides is the largest and most prevalent helminth seen in the human body. Ascariasis having high morbidity and mortality causes a unique type of intestinal obstruction with specific problems. This is probably due to reduced intestinal absorption and luminal obstruction, which can lead to anorexia and blockage of the absorbing surface. It affects humans especially in developing countries. This essay presented a 78-year-old female case had severe abdominal pain, nausea and constipation for seven days and the pylorus was obstructed by A. lumbricoides and diagnosis was obtained by endoscopy. During endoscopy in the treatment, the ascariasis that could be removed was. Afterwards, 100 mg mebendazole was given for 3 days once in two months.The purpose of the presentation of this case is that it is seen in advanced ages and it sets us thinking of stomach tumor due to its obstruction and anemia clinic.

    The objective of this study was to determine whether 2 distinct chlamydial isolates recovered from the intestines and feces of diarrheic nursery pigs could cause intestinal lesions in gnotobiotic pigs. Both isolates share biological characteristics with Chlamydia trachomatis. Chlamydial isolates R27 and R19 were propagated in Vero cells or embryonated eggs, respectively, and suspended in sucrose-phosphate-glutamine buffer with 10% fetal bovine serum for inoculation. Sham inocula were prepared from uninfected cell culture lysates and from uninfected eggs. Each piglet was fed 1 ml of inoculum or sham inoculum at 3-4 days of age. Ten piglets were each fed 10(9) inclusion-forming-units (IFU) and 14 piglets were each fed 10(6) IFU of isolate R27; 5 control piglets were fed sham inoculum. Twenty piglets were each fed 10(5) IFU R19; 5 control piglets were fed sham inoculum. All infected piglets developed diarrhea 4-5 days postinfection (DPI). Most piglets fed 10(9) IFU R27 became anorexic, dehydrated, and weak and were necropsied 4-7 DPI. Piglets fed 10(6) IFU R27 or 10(5) IFU R19 were necropsied 4, 7, 10, 14, and 18 DPI. Diarrhea, although never profuse, persisted in the piglets fed 10(6) IFU R27 or 10(5) IFU R19 through 12 DPI. At necropsy, all diarrheic piglets had watery colonic contents with flecks of undigested curd. In small intestine, histologic lesions were seen most consistently in distal jejunum and ileum. Distal jejunum and ileum from piglets fed 10(9) IFU R27 and necropsied 4-5 DPI were characterized by villus atrophy and multifocal necrosis of villi; necrosis was limited to the tips or apical one half of villi. Mild to severe villus atrophy, lymphangitis, and perilymphangitis were seen in the distal jejunum and ileum from all infected piglets 7 and 10 DPI. Colon from 1 infected piglet necropsied 10 DPI had mild focal serositis; significant colonic lesions were not seen in the other infected piglets. Immunostaining done on sections of distal jejunum and ileum

    A 10-year-old, castrated male domestic short hair cat was presented to the Small Animal Clinic at the Western College of Veterinary Medicine with a presenting complaint of chronic, ocular discharge from the left eye. Ocular examination confirmed epiphora and mucopurulent discharge but there were no apparent reasons for the ocular discharge, and nasolacrimal obstruction was suspected. The cat had swelling of the left side of the face, severe periodontal disease and a fractured upper left canine tooth with pulpal exposure. Dacryocystorhinography revealed narrowing of the nasolacrimal duct above the root of the fractured upper left canine and dental radiographs showed a severe periapical lucency at the apex of the upper left canine tooth. The fractured canine tooth was removed. Subsequently, the ocular discharge and facial swelling resolved. After 2 years, the epiphora has never reoccurred. This is a noteworthy case because a suspected root abscess resulted in extralumenal compression of the nasolacrimal duct, which shows the importance of a thorough oral examination when nasolacrimal obstruction is evident.

    Introduction Sinusoidal obstruction syndrome (SOS) is a severe adverse event of long-term chemotherapy in patients with colorectal cancer. It usually develops as liver congestion due to diffuse microscopic obstruction in liver parenchyma. In contrast, it sometimes appears as a liver mass occurring with local parenchymal hemorrhaging, and is often misdiagnosed as liver metastasis. Case Presentation A 40-year-old woman with rectal cancer underwent high anterior resection and partial liver resection of segment 7 due to synchronous liver metastasis. She received oxaliplatin-based chemotherapy (mFOLFOX6) as adjuvant chemotherapy for 6 months. A 13-mm irregular low-echoic mass was detected by CT in segment 3 of the liver 12 months after the operation. The mass was again resected as a liver metastasis because it had increased in size. The pathological diagnosis was focal SOS, which showed sinusoidal dilation and congestion by hepatocyte trabeculae in the liver parenchyma. Conclusions Atypical irregular tumors should be considered as SOS when the patient has received oxaliplatin-based chemotherapy. A qualitative imaging modality diagnosis, such as with diffusion-weighted MRI, is superior to a morphological diagnosis in focal SOS. This imaging modality can prevent unnecessary operations.

    Urinary obstruction of the transplanted kidney caused by uterine leiomyoma is an extremely rare condition. To the best of our knowledge, there are only two reports in English literature. Psoas abscess secondary to renal graft pyelonephritis is also uncommon. We present this unusual case and its treatment course. A 43-year-old female presented with renal dysfunction. She was started on peritoneal dialysis from the age of 26 years and received kidney transplantation from her mother (living donor) at the age of 27 years. Computed tomography (CT) revealed right hydronephrosis and a large uterine mass compressing the distal ureter of the transplanted kidney. After a simple total hysterectomy, her renal function improved. Two years following the hysterectomy, she experienced painful urination, fever, right abdominal pain, and right lower limb pain. CT and T2-weighed magnetic resonance imaging of her pelvis demonstrated right psoas abscess in conjunction with transplanted kidney. She was treated with broad-spectrum antibiotics alone, which resulted in a good response. Urinary obstruction of the transplanted kidney caused by uterine leiomyoma is an extremely rare condition. Psoas abscess secondary to transplanted kidney pyelonephritis is also rare. We should keep these rare diseases in mind when treating such cases. PMID:28097036

    We report the successful management of acute cholecystitis using cystic duct stent placement in 3 patients with inoperable malignant cystic duct obstruction (2 cholangiocarcinoma and 1 pancreatic carcinoma). All patients underwent stent placement in the bile duct, using an uncovered stent in 2 and a covered stent in 1, to relieve jaundice occurring 8-184 days (mean 120 days) before the development of acute cholecystitis. The occluded cystic duct was traversed by a microcatheter and a stent was implanted 4-17 days (mean 12 days) after cholecystostomy. Acute cholecystitis was improved after the procedure in all patients. Two patients died 3 and 10 months later, while 1 has survived without cholecystitis for 22 months after the procedure to date.

    Duodenal obstruction caused by abdominal aortic aneurysm was first described by Osler in 1905 and is named "aortoduodenal syndrome." This condition has always been treated by open surgical repair. We report the first case of aortoduodenal syndrome successfully treated by endovascular aneurysm repair. A 74-year-old male patient referred to our hospital complaining postprandial vomit, reporting a consistent weight loss in the latest weeks. Enhanced computed tomography scans showed a small saccular abdominal aortic aneurysm compressing duodenum and inferior vena cava without any other evident pathological finding. As the patient underwent a successful endovascular treatment of the abdominal aortic aneurysm, symptoms immediately resolved so that he started back to feed and progressively gained body weight. Despite aortoduodenal syndrome is generally caused by large abdominal aortic aneurysm, this condition has to be suspected also in case of small abdominal aortic aneurysm. Differently from what has been reported in literature, endovascular aneurysm repair could be effective in the treatment of aortoduodenal syndrome.

    OHVIRA (Obstructed hemivagina and ipsilateral renal anomaly) by acronym and abbreviations in English or Herlyn Werner Wunderlich syndrome is a rare congenital malformation caused by an alteration in the Mullerian ducts and Wolffian Ducts. Which is characterized by a triad: uterus didelphys, obstructed and ipsilateral renal agenesis hemivagina still uncertain etiology. Patients are usually asymptomatic until menarche where the most common clinical presentation is pelvic pain, followed by a vaginal or abdominal mass, normal menstrual periods, infertility, and vaginal discharge rarely appears. The case of a female patient of 15 years, nubile with chronic fetid vaginal discharge, initially diagnosed and treated as pelvic inflammatory disease occurs, however because it is an exceptional condition with the background of the patient, by complementary studies were conducted where pelvic ultrasound revealed pyocolpos and absence of left kidney, uterus didelphys, blind hemivagina by other imaging studies, where we could integrate Herlyn-Werner-Wunderlich syndrome. In conclusion, abnormalities in the development of the Miillerian ducts are difficult to diagnose early, so you must have the embryological knowledge, conduct thorough clinical assessment and detailed picture in whom the coridition is suspected to identify malformations coexisting urinary tract and vaginal defects with the importance of preserving reproductive success through appropriate planning of surgical approach, given that the fertility rate in these patients is comparable to the average.

    Azoospermia is of great importance to male infertility. Obstructive azoospermia (OA) due to infection is the most prevalent form of OA in China and has been less studied. We aim to observe the treatment outcome of microsurgical vasoepididymostomy (VE) and also to identify the factors relative to the result after reconstructive surgery. Two hundred and eight men presenting with OA due to infection during the study period from July 2010 to July 2013 were prospectively evaluated. Clinical examination, semen analysis, serum follicle stimulating hormone (FSH), and scrotal ultrasound were done before surgical exploration. Among the 198 men who were selected for surgical procedures, 159 candidates underwent microsurgical VE with sperm detected in the epididymal fluid. As for the other 39 cases, reconstruction was not feasible. The average age was 28.5 ± 3.9 years (range 22–38), with average follow-up being 16.5 ± 5.9 months (range 4–28). According to the 150 cases being followed after VE procedures, the total patency rate was 72% (108/150). During follow-up, 38.7% (58/150) natural pregnancies occurred, with overall live birth rate being 32.7% (49/150). Our data suggested that microsurgical VE is an effective therapy for postinfectious epididymal OA. Individualized counseling with prognosis based on etiology should be offered to patients to select optical therapy. PMID:26924282

    An aggressive array of new treatments and improvements of existing approaches for addressing morbid obesity were developed during the last two decades in response to the recognition that a new pandemic affects humanity, i.e. obesity. Initially used as a temporizing solution for other specific interventions used for obesity treatment, the endoscopic placement of an intragastric balloons has currently became in certain cases a complete therapeutic solution. Multiple studies emphasize the efficiency of this new therapeutic method, in some cases resulting in a 45 kg weight loss at the end of the monitoring period. The intragastric balloon, after endoscopic placement can be kept into position for an average period of 4-6 months. After this period, balloon extraction is recommended because of the complications that can occur with prolonged intragastric placement. This paper presents a case of pyloric obstruction by an intragastric balloon kept for 14 months. In this case, the initial approach was endoscopic, but the surgical approach offered the definitive therapeutic solution.

    Defective collagen biosynthesis in Marfan syndrome predisposes to dural defects such as dural ectasia, meningocele, and pseudomeningocele; thus, an increased index of suspicion for these conditions should be present in the clinical setting of Marfan syndrome. The authors describe a young woman with Marfan syndrome who was being treated with anticoagulants for a prosthetic heart valve and who presented with a spontaneous retroperitoneal hemorrhage requiring surgical evacuation. No CSF leak was encountered at surgery, but she developed progressively more severe positional headaches over the following year. She then experienced the sudden onset of acute urinary obstruction, at which time CT revealed a 17 × 15 × 13-cm presacral pseudomeningocele communicating with the thecal sac through a sacral bone defect. An anterior surgical approach was used for drainage of the pseudomeningocele as well as for primary closure of the dural defect with a bovine pericardial patch and autologous subcutaneous fat graft. After a short period of lumbar subarachnoid drainage of the CSF, the patient was able to resume normal activity without recurrent symptoms. To the authors' knowledge, such a pseudomeningocele in a patient with Marfan syndrome has been reported only twice, and this case features the largest pseudomeningocele to date. They also review the pertinent literature regarding presentation, diagnosis, and management of these lesions.

    Patients with systemic lupus erythematosus (SLE) have a higher incidence rate of tuberculosis and a more frequent extrapulmonary involvement than the general population. We present 2 SLE patients who developed gastrointestinal tuberculosis complicated with intestinal perforation, a rare but serious complication that could be confused with lupus-associated intestinal vasculitis. Opportunistic infections such as tuberculosis must be suspected in SLE patients with abdominal symptoms on immunosuppressive therapy because its early recognition could prevent catastrophic complications such as intestinal perforation and subsequent peritonitis.

    Unilateral ureteral obstruction is a popular experimental model of renal injury. However, the study of the kidney response to urinary tract obstruction is only one of several advantages of this model. Unilateral ureteral obstruction causes subacute renal injury characterized by tubular cell injury, interstitial inflammation and fibrosis. For this reason, it serves as a model both of irreversible acute kidney injury and of events taking place during human chronic kidney disease. Being a unilateral disease, it is not useful to study changes in global kidney function, but has the advantage of a low mortality and the availability of an internal control (the non-obstructed kidney). Experimental unilateral ureteral obstruction has illustrated the molecular mechanisms of apoptosis, inflammation and fibrosis, all three key processes in kidney injury of any cause, thus providing information beyond obstruction. Recently this model has supported key concepts on the role in kidney fibrosis of epithelial-mesenchymal transition, tubular epithelial cell G2/M arrest, the anti-aging hormone Klotho and renal innervation. We now review the experimental model and its contribution to identifying novel therapeutic targets in kidney injury and fibrosis, independently of the noxa.

    Our primary aim in this study was to test the hypothesis that PEA, a member of the fatty acid ethanolamide family and an endogenous PPAR-α ligand, exerts anti-inflammatory effects on SAO shock, causing a severe form of circulatory shock and enhanced formation of ROS. SAO shock was induced by clamping the superior mesenteric artery and the celiac trunk, resulting in a total occlusion of these arteries for 30 min. After this period of occlusion, the clamps were removed. In this study, we demonstrated that the administration of PEA, 5 min before reperfusion, significantly reduced all of the parameters involved during inflammation, such as proinflammatory cytokine production (TNF-α, IL-1β), adhesion molecules (ICAM-1, P-selectin) expression, NF-κB expression, and apoptosis (Bax, Bcl-2, TUNEL assay) activation. In addition, to study whether the protective action of PEA on SAO shock is also related to the activation of PPAR-α, we have investigated the effect of PEA in PPAR-α KO mice subjected to SAO shock. Our study clearly demonstrates that PEA significantly attenuated the degree of intestinal injury and inflammation caused by I/R injury. Moreover, the positive effects of PEA were at least in part dependent on the PPAR-α pathway. The results clearly indicate that PEA exerts an anti-inflammatory effect, also in a SAO shock model, which could imply a future use of PEA in the treatment of I/R shock.

    To elucidate the pathophysiological changes leading to postantibiotic diarrhoea caused by Clostridium difficile and its cytotoxin, oral ampicillin was given to rabbits, and jejunal, ileal, and caecal segments of those that developed diarrhoea were investigated in vitro. The rabbits that, in response to treatment, harboured Clostridium difficile in their colonic lumen were studied, and the results expressed according to the presence or absence of Clostridium difficile and/or its cytotoxin. Thus, we refer to either CD+ or CD- segments. The influx of glucose, phenylalanine, glycylphenylalanine, and lysine across the brush border of jejunum and ileum of CD+ segments was severely impaired, while only slightly blunted in CD-. No significant change was detected in the influx of glutamic acid in the jejunum of all treated animals and in the CD- ilea. Morphologic damage in ileum and caecum of CD+ was also more evident than in CD-. Transepithelial ion transport across short circuited ileal mucosa (CD+ and CD-) revealed secretory changes in Cl net transport that were more marked in CD-. We conclude that: (1) Clostridium difficile may also colonise the upper intestinal tract, where it induces morphological and functional damage, severely impairing nutrient absorption; and (2) the ileum contributes to the diarrhoea caused by CD even when the micro-organism is confined to the more distal gut by showing moderate impairment of nutrient absorption and marked electrolyte secretion.

    Using denaturing gradient gel electrophoresis and direct sequencing of amplified genomic DNA, the authors have identified two defective mutants of the human [alpha][sub 1]-antichymotrypsin (ACT) gene associated with chronic obstructive pulmonary disease (COPD). A leucine 55-to-proline substitution causing a defective ACT allele (Bochum-1) was observed in a family with COPD in three subsequent generations. Another mutation, proline 229-to-alanine (Bonn-1), was associated with ACT serum deficiency in four patients with a positive family history. These mutations were not detected among 100 healthy control subjects, suggesting a possible pathogenetic role of ACT gene defects in a subset of patients with COPD. 14 refs., 1 fig., 1 tab.

    Retropharyngeal haematoma (RH) is an extremely rare but potentially life-threatening condition that requires an early diagnosis and immediate management. Acute complications arise from compression and obstruction of the upper airway and oesophagus with the risk of consecutive aspiration. We present the case of a 48-year-old man with formation of a RH after accidental ingestion of a large fish bone with hypertension as comorbidity caused by a so far undiagnosed pheochromocytoma. The patient presented with acute onset of retropharyngeal pain, dysphonia and dysphagia secondary to fish bone foreign body ingestion. His medical history was significant for uncontrolled hypertension. CT showed a large RH extending from the oropharynx to the superior mediastinum. The patient underwent emergency tracheostomy, surgical debridement and removal of the fish bone. Antihypertensive medication was utilised to control his labile blood pressure. The postoperative CT scan revealed an adrenal pheochromocytoma that was subsequently resected. PMID:25759272

    This case report shows that 3D perineal ultrasound can be superior to clinical examination and routine 2D perineal ultrasound in the detection of an unusual subpubic tumor. A 73-year-old female patient was referred to our urogynecological outpatient unit complaining of over-active bladder symptoms and voiding dysfunction for 3 years. Gynecological examination found no signs of pelvic organ prolapse or abnormality in the vaginal cavity. Routine 2D perineal ultrasound showed substantial residual urine (ca. 300 ml on catheter) and limited bladder neck mobility, but no signs of pelvic organ prolapse. Use of standardized 3D perineal ultrasound revealed a 24 × 26 × 32 mm spherical, hypoechoic tumor below the pubic symphysis between the distal urethra and the pubic bones. This structure was mistaken for the pubic symphysis in the midline on 2D ultrasound performed earlier. At surgery, the tumor was completely excised through a vaginal incision between the urethra and the pubic symphysis. After an uneventful postoperative recovery the patient developed de-novo stress urinary incontinence, which was corrected successfully by the insertion of a retropubic tension-free suburethral sling after an interval of 8 weeks. After a further follow-up of 8 weeks the patient reported well-being, urinary continence and no voiding dysfunction; no abnormalities were found on examination. In conclusion, 3D perineal ultrasound is a useful additional tool for the diagnostic workup of bladder outlet obstruction.

Arrested midgut rotation results due to narrow-based mesentery and increases the risk of twisting midgut and subsequent obstruction and necrosis. Presentation of case 40 years old female patient admitted to emergency service with acute abdomen and computerized tomography scan showed dilated large and small intestine segments with air-fluid levels and twisted mesentery around superior mesenteric artery and vein indicating “whirpool sign”. Discussion Malrotation in adults is a rare cause of midgut volvulus as though it should be considered in differential diagnosis in patients presented with acute abdomen and intestinal ischemia. Even though clinical symptoms are obscure, adult patients usually present with vomiting and recurrent abdominal pain due to chronic partial obstruction. Contrast enhanced radiograph has been shown to be the most accurate method. Typical radiological signs are corkscrew sign, which is caused by the dilatation of various duodenal segments at different levels and the relocation of duodenojejunal junction due to jejunum folding. As malrotation commonly causes intestinal obstruction, patients deserve an elective laparotomy. Conclusion Malrotation should be considered in differential diagnosis in patients presented with acute abdomen and intestinal ischemia. Surgical intervention should be prompt to limit morbidity and mortality. PMID:27015011

    Diarrheal diseases are among the leading causes of morbidity and mortality in the world, particularly among young children. A limited number of infectious agents account for most of these illnesses, raising the hope that advances in the treatment and prevention of these infections can have global health impact. The two most important parasitic causes of diarrheal disease are Cryptosporidium and Giardia. Both parasites infect predominantly the small intestine and colonize the lumen and epithelial surface, but do not invade deeper mucosal layers. This review discusses the therapeutic challenges, current treatment options, and drug development efforts against cryptosporidiosis and giardiasis. The goals of drug development against Cryptosporidium and Giardia are different. For Cryptosporidium, only one moderately effective drug (nitazoxanide) is available, so novel classes of more effective drugs are a high priority. Furthermore, new genetic technology to identify potential drug targets and better assays for functional evaluation of these targets throughout the parasite life cycle are needed for advancing anticryptosporidial drug design. By comparison, for Giardia, several classes of drugs with good efficacy exist, but dosing regimens are suboptimal and emerging resistance begins to threaten clinical utility. Consequently, improvements in potency and dosing, and the ability to overcome existing and prevent new forms of drug resistance are priorities in antigiardial drug development. Current work on new drugs against both infections has revealed promising strategies and new drug leads. However, the primary challenge for further drug development is the underlying economics, as both parasitic infections are considered Neglected Diseases with low funding priority and limited commercial interest. If a new urgency in medical progress against these infections can be raised at national funding agencies or philanthropic organizations, meaningful and timely progress is possible

    Introducción: la elección de una incisión para laparotomía depende del área que necesite ser expuesta, la urgencia del procedimiento y las preferencias del cirujano. En el Hospital de Pediatría del Centro Médico Nacional Siglo XXI del IMSS, tradicionalmente se realiza abordaje por línea media en estos pacientes. Nuestro objetivo fue determinar si el abordaje por línea media es seguro para el manejo de neonatos sometidos a laparotomía por oclusión intestinal. Métodos: estudio retrospectivo que incluyó a todos los neonatos sometidos a laparotomía por oclusión intestinal mediante abordaje por línea media, en un período comprendido entre enero 2010 a enero 2012. Resultados: se estudiaron 34 pacientes. El 88.2 % de los procedimientos fueron de urgencia. Se encontraron complicaciones en 44 % de los pacientes, de las cuales la más frecuentes fueron: infección y dehiscencia de herida. Dentro de las complicaciones respiratorias, el 32.4 % presentó atelectasia y el 14.7 %, neumonía. Tuvieron hernia postincisional al año el 14.7 %. Ninguna de las variables del paciente o la cirugía fueron estadísticamente significativas para el desarrollo de complicaciones. Se presentaron más complicaciones en los procedimientos de urgencia, en pacientes menores a 2000 gramos y con tiempos quirúrgicos mayores a 120 minutos. Conclusiones: la frecuencia de complicaciones inmediatas y mediatas posteriores al evento quirúrgico son mayores a las reportadas en la literatura con abordaje transverso. La frecuencia de hernia postincisional al año es similar a lo reportado con éste último abordaje.

    Diffuse nodular lymphoid hyperplasia of the gastrointestinal tract is a rare disease characterized by numerous small polypoid nodules in the small intestine, large intestine, or both. It is associated with immunodeficiency and infection, such as Giardia lamblia and Helicobacter pylori. Although diffuse nodular lymphoid hyperplasia associated with common variable immunodeficiency (CVID) and giardiasis is already known, a few studies have reported a regression of the lymphoid nodules after the eradication of infection. We herein describe a case of diffuse nodular lymphoid hyperplasia of the intestine associated with CVID and refractory giardiasis that markedly improved after successfully treating giardiasis.

    Enteric intussusception caused by primary intestinal malignant melanoma is a very rare cause of intestinal obstruction. We herein present a case of a 42-year-old female patient with no prior medical history of malignant melanoma, who was admitted with persistent abdominal pain, nausea, and vomiting. A computed tomography scan revealed an intestinal obstruction due to ileocolic intussusception. An emergency laparoscopy and subsequent laparotomy revealed multiple small solid tumors across the whole small bowel. An oncologic resection was not feasible due to the insufficient length of the remaining small bowel. Only a small segment of ileum, which included the largest tumors causing the intussusception, was resected. The pathologic examination revealed two intestinal malignant melanoma lesions. A systematic clinical examination, endoscopic procedures, and fluorodeoxyglucose positron emission tomography-computed tomography scan all failed to reveal any indication of cutaneous, anal, or retinal melanoma. Hence, the tumor was classified as a primary intestinal malignant melanoma with multiple intestinal metastases. Since a complete oncologic resection of tumors was not possible, in order to prevent future intestinal obstruction, a surgical resection of the largest lesions was performed with palliative intention. The epidemiology, clinical manifestations, diagnosis and management of primary intestinal malignant melanoma, and intestinal intussusception in adults are discussed along with a review of the current literature.

    A bullet, lodged in the pineal-posterior region of the third ventricle and causing obstructive hydrocephalus, was removed without damage to critical adjacent vascular structures using stereotactic localization followed by laser-guided stereotactic craniotomy. Stereotactic techniques provided precise target localization and allowed dissection to be restricted to the previously injured missile track, thus avoiding any additional morbidity from the surgical procedure.

    In patients with biliary atresia, portal vein problems may cause challenges for liver transplant. Interposition grafts have been used for vascular anastomoses in transplant recipients with varied success. A cryopreserved iliac artery graft was used for the reconstruction of the portal vein in a 29-month-old infant with biliary atresia. At 17 months after transplant, she developed upper gastrointestinal bleeding that was caused by portal vein occlusion because of vascular calcifications in the graft. Upper gastrointestinal endoscopy showed esophageal varices with fresh bleeding, and the varices were band ligated. At 3 months after the bleeding episode, the patient was asymptomatic and biochemical tests were normal. In summary, liver transplant with cryopreserved iliac artery graft may be complicated by calcifications and portal vein occlusion, and caution is advised in using this graft material for portal vein anastomoses.

    Megacystis-microcolon-intestinal hypoperistalsis syndrome is a multisystemic disorder in which impaired intestinal motor activity causes recurrent symptoms of intestinal obstruction in the absence of mechanical occlusion, associated with bladder distention without distal obstruction of the urinary tract. It is an uncommon disorder with high morbidity and mortality, and long-term total parenteral nutrition may be required. We describe an 18-year-old girl with long-term survival, followed-up by our service since birth. With medical, surgical and nutritional management she currently presents a good oral tolerance and good quality of life, only requiring parenteral nutrition during periods of decompensation.

    Foreign body ingestion is common in patients with psychiatric diagnoses. Ingested objects can become impacted in the upper and lower gastrointestinal tract, causing serious complications. We report a case of a schizophrenic who ingested large pieces of computer circuit boards, which impacted at the mid-esophagus, in the stomach, and in the cecum. Endoscopic removal of the esophageal object was unsuccessful, and the foreign objects were removed by esophagotomy and laparotomy. Expeditious removal through endoscopic or surgical means is extremely important, as complications can be life-threatening. This is the first report of ingestion of a computer printed circuit board.

    The authors compared the results of mycologic examinations of asthmatic and control patient's throat. Fungi other than Candida were cultivated from the throat in 15% of asthmatic children and 3% of controls. In secrets from the lower respiratory tract gained by bronchoscopy, laryngoscopy, or through tracheostomy there were moulds in 34% among the asthmatics and in 15% of the other cases. Allergic respiratory tract diseases facilitate the harbouring of moulds in the respiratory tract but do not influence the presence of Candida albicans. Moulds could often be cultivated even in patient not allergic to them. However there are chronic cases caused by immun reaction to the moulds in the patients' respiratory tract. Microscopic detection of budding and branching, myceliform fungi in the secret produced by coughing supports the diagnosis of mould causing chronic asthmoid bronchitis. New peroral broad spectrum antimycotics facilitate the treatment of such cases. The authors succesfully treated some patients with Clotrimazol (Canesten, Bayer) and all cases responded well to 5-Fluorocytosan (Ancotyl, Roche).

    Interleukin-11 is a pleotropic cytokine produced by lung stromal cells in response to respiratory viruses, cytokines, and histamine. To further define its potential effector functions, the Clara cell 10-kD protein promoter was used to express IL-11 and the airways of the resulting transgene mice were characterized. In contrast to transgene (-) littermates, the airways of IL-11 transgene (+) animals manifest nodular peribronchiolar mononuclear cell infiltrates and impressive airways remodeling with subepithelial fibrosis. The inflammatory foci contained large numbers of B220(+) and MHC Class II(+) cells and lesser numbers of CD3(+), CD4(+), and CD8(+) cells. The fibrotic response contained increased amounts of types III and I collagen, increased numbers of alpha smooth muscle actin and desmin-containing cells and a spectrum of stromal elements including fibroblasts, myofibroblasts, and smooth muscle cells. Physiologic evaluation also demonstrated that 2-mo-old transgene (+) mice had increased airways resistance and non-specific airways hyperresponsiveness to methacholine when compared with their transgene (-) littermates. These studies demonstrate that the targeted expression of IL-11 in the mouse airway causes a B and T cell-predominant inflammatory response, airway remodeling with increased types III and I collagen, the local accumulation of fibroblasts, myofibroblasts, and myocytes, and obstructive physiologic dysregulation. IL-11 may play an important role in the inflammatory and fibrotic responses in viral and/or nonviral human airway disorders. PMID:8981933

    Background Renal tubulointerstitial fibrosis is a common feature of the final stage of nearly all cause types of chronic kidney disease. Although classic peroxisome proliferator-activated receptor γ (PPARγ) agonists have a protective effect on diabetic nephropathy, much less is known about their direct effects in renal fibrosis. This study aimed to investigate possible beneficial effects of lobeglitazone, a novel PPARγ agonist, on renal fibrosis in mice. Methods We examined the effects of lobeglitazone on renal tubulointerstitial fibrosis in unilateral ureteral obstruction (UUO) induced renal fibrosis mice. We further defined the role of lobeglitazone on transforming growth factor (TGF)-signaling pathways in renal tubulointerstitial fibrosis through in vivo and in vitro study. Results Through hematoxylin/eosin and sirius red staining, we observed that lobeglitazone effectively attenuates UUO-induced renal atrophy and fibrosis. Immunohistochemical analysis in conjunction with quantitative reverse transcription polymerase chain reaction and Western blot analysis revealed that lobeglitazone treatment inhibited UUO-induced upregulation of renal Smad-3 phosphorylation, α-smooth muscle actin, plasminogen activator inhibitor 1, and type 1 collagen. In vitro experiments with rat mesangial cells and NRK-49F renal fibroblast cells suggested that the effects of lobeglitazone on UUO-induced renal fibrosis are mediated by inhibition of the TGF-β/Smad signaling pathway. Conclusion The present study demonstrates that lobeglitazone has a protective effect on UUO-induced renal fibrosis, suggesting that its clinical applications could extend to the treatment of non-diabetic origin renal disease.

    A 42-year-old woman presented with a 4-year history of worsening diarrhoea that was watery, profuse and confirmed to be secretory in nature. She had tested positive for phenolphthalein on urinary laxative screening but continued to deny laxative usage. Her vasoactive intestinal polypeptide (VIP) level was subsequently found to be markedly elevated. Despite a normal abdominal ultrasound, a computed tomography scan revealed a 5-cm pancreatic tail mass. Octreotide scanning was used to exclude metastatic disease and she went on to have surgical removal of a localized pancreatic vasoactive intestinal polypeptide-oma which resulted in the complete resolution of her diarrhoea.

    β-Conglycinin has been identified as one of the major feed allergens. However, studies of β-conglycinin on fish are scarce. This study investigated the effects of β-conglycinin on the growth, digestive and absorptive ability, inflammatory response, oxidative status and gene expression of juvenile Jian carp (Cyprinus carpio var. Jian) in vivo and their enterocytes in vitro. The results indicated that the specific growth rate (SGR), feed intake, and feed efficiency were reduced by β-conglycinin. In addition, activities of trypsin, chymotrypsin, lipase, creatine kinase, Na(+),K(+)-ATPase and alkaline phosphatase in the intestine showed similar tendencies. The protein content of the hepatopancreas and intestines, and the weight and length of the intestines were all reduced by β-conglycinin. β-Conglycinin increased lipid and protein oxidation in the detected tissues and cells. However, β-conglycinin decreased superoxide dismutase (SOD), catalase (CAT), glutathione-S-transferase (GST), glutathione peroxidase (GPx) and glutathione reductase (GR) activities and glutathione (GSH) content in the intestine and enterocytes. Similar antioxidant activity in the hepatopancreas was observed, except for GST. The expression of target of rapamycin (TOR) gene was reduced by β-conglycinin. Furthermore, mRNA levels of interleukin-8 (IL-8), tumor necrosis factor-α (TNF-α), and transforming growth factor-β (TGF-β) genes were increased by β-conglycinin. However, β-conglycinin increased CuZnSOD, MnSOD, CAT, and GPx1b gene expression. In conclusion, this study indicates that β-conglycinin induces inflammation and oxidation, and causes dysfunction of intestinal digestion and absorption in fish, and finally reduces fish growth. The results of this study provide some information to the mechanism of β-conglycinin-induced negative effects.

    Background: To investigate the antiapoptotic effect of Ukrain on intestinal lesion induced by mesenteric ischemia-reperfusion (I/R) injury. Methods: Male Sprague-Dawley rats were divided into three groups: laparotomy (L), I/R, and Ukrain and I/R (U + I/R). In the U + I/R group, Ukrain (7 mg/kg) was given by intraperitoneal at the beginning of the study. 1 h after ukrain application, ischemia was induced for 30 minutes, and reperfusion was subsequently allowed for 120 minutes in the I/R and U + I/R groups. Rats were sacrificed at the end of reperfusion and intestinal tissues were collected for biochemical and molecular examination. Intestinal tissues caspase 3 protein were assayed. Serum Bcl-xL and iNOS were measured. The expression level of caspase-3, Bcl-xL and iNOS in intestinal tissue of rats were detected by reverse transcription-polymerase chain reaction (RT-PCR). Results: Levels of serum iNOS and mRNA expression were increased in the I/R and decreased in the U + I/R group. In addition, levels of the proapoptotic gene caspase-3 protein and mRNA expression were increased in the I/R and decreased in the U + I/R group. Levels of the antiapoptotic gene Bcl-xL serum and mRNA expression were increased in the U + I/R group. Conclusions: Ukrain can reduce the ischemia-reperfusion injury in the intestinal tissue by inhibiting the cell apoptosis. The mechanism may be correlated with increased Bcl-xL mRNA expressions and decreased mRNA expressions of Caspase-3 and iNOS. PMID:26885190

    Hyperemesis gravidarum can cause various vitamin deficiencies. Vitamin K deficiency can lead to coagulopathy or hemorrhagic diathesis. A nulliparous Japanese woman with hyperemesis gravidarum at 105/7 weeks was admitted with giant myoma, intestinal obstruction, and abdominal pain. Treatment for a degenerative myoma was instituted with intravenous antibiotics. The abdominal pain ameliorated, but intestinal obstruction persisted. At 166/7 weeks, we performed laparotomy for release of intestinal obstruction, when intraabdominal bleeding of 110 mL existed. Blood tests revealed coagulopathy secondary to vitamin K deficiency. The coagulopathy responded to intravenous vitamin K injection. Coagulopathy due to vitamin K deficiency can occur with hyperemesis gravidarum, and coexisting intestinal obstruction and broad-spectrum antibiotics can aggravate the deficiency. PMID:27597910

    Oxaliplatin-based chemotherapy is widely used to treat advanced colorectal cancer (CRC). Sinusoidal obstruction syndrome (SOS) due to oxaliplatin is a serious type of chemotherapy-associated liver injury (CALI) in CRC patients. SOS is thought to be caused by the sinusoidal endothelial cell damage, which results in the release of unusually-large von Willebrand factor multimers (UL-VWFMs) from endothelial cells. To investigate the pathophysiology of CALI after oxaliplatin-based chemotherapy, we analyzed plasma concentration of von Willebrand factor (VWF) and the distribution of VWFMs in CRC patients. Twenty-three patients with advanced CRC who received oxaliplatin-based chemotherapy with (n = 6) and without (n = 17) bevacizumab were analyzed. CALI (n = 6) and splenomegaly (n = 9) were found only in patients who did not treated with bevacizumab. Plasma VWF antigen (VWF:Ag) and serum aspartate aminotransferase (AST) levels increased after chemotherapy only in patients without bevacizumab. VWFM analysis in patients who did not receive bevacizumab showed the presence of UL-VWFMs and absence of high molecular weight VWFMs during chemotherapy, especially in those with CALI. In addition, plasma VWF:Ag and AST levels increased after chemotherapy in patients with splenomegaly (n = 9), but not in patients without splenomegaly (n = 14). Histological findings in the liver tissue of patients who did not receive bevacizumab included sinusoidal dilatation and microthrombi in the sinusoids. Many microthrombi were positive for both anti-IIb/IIIa and anti-VWF antibodies. Plasma UL-VWFM levels might be increased by damage to endothelial cells as a result of oxaliplatin-based chemotherapy. Bevacizumab could prevent CALI and splenomegaly through inhibition of VWF-rich platelet thrombus formation. PMID:26580395

    Objectives. The aim of this study was to detect factors associated with small bowel obstruction (SBO) caused by bezoars on multidetector computed tomographic findings. Methods. We retrospectively reviewed 61 patients who had bezoars in the small bowels on MDCT. The patients were divided into SBO patients group and non-SBO patients group. The mean values of the diameter, volume, and CT attenuation as well as location and characteristics of the bezoars were compared between the two groups. Multivariate analysis was performed to determine factors associated with SBO. Results. There were 32 patients (52.5%) in the SBO group and 29 patients (47.5%) in the non-SBO group. The bezoars in the SBO group had greater values of each mean diameter and mean volume than those in the non-SBO group (3.2 ± 0.5 cm versus 1.6 ± 0.7 cm, P < 0.0001, 14.9 ± 6.4 cm3 versus 2.5 ± 2.7 cm3, P < 0.0001, resp.) and had a lower CT attenuation than the non-SBO group (55.5 ± 23.4 versus 173.0 ± 68.0, P < 0.0001). The SBO group had higher prevalence of phytobezoar appearance (75.0% versus 10.3%, P < 0.0001). Major diameters of bezoar and phytobezoar were significant independent risk factors associated with SBO (odds ratio = 36.09, 8.26, resp., and P = 0.0004, 0.044, resp.). Conclusions. Major diameter of bezoar or phytobezoar is a potential risk factor associated with SBO. PMID:27403434

    Intestinal lymphangiectasia in the adult may be characterized as a disorder with dilated intestinal lacteals causing loss of lymph into the lumen of the small intestine and resultant hypoproteinemia, hypogammaglobulinemia, hypoalbuminemia and reduced number of circulating lymphocytes or lymphopenia. Most often, intestinal lymphangiectasia has been recorded in children, often in neonates, usually with other congenital abnormalities but initial definition in adults including the elderly has become increasingly more common. Shared clinical features with the pediatric population such as bilateral lower limb edema, sometimes with lymphedema, pleural effusion and chylous ascites may occur but these reflect the severe end of the clinical spectrum. In some, diarrhea occurs with steatorrhea along with increased fecal loss of protein, reflected in increased fecal alpha-1-antitrypsin levels, while others may present with iron deficiency anemia, sometimes associated with occult small intestinal bleeding. Most lymphangiectasia in adults detected in recent years, however, appears to have few or no clinical features of malabsorption. Diagnosis remains dependent on endoscopic changes confirmed by small bowel biopsy showing histological evidence of intestinal lymphangiectasia. In some, video capsule endoscopy and enteroscopy have revealed more extensive changes along the length of the small intestine. A critical diagnostic element in adults with lymphangiectasia is the exclusion of entities (e.g. malignancies including lymphoma) that might lead to obstruction of the lymphatic system and "secondary" changes in the small bowel biopsy. In addition, occult infectious (e.g. Whipple's disease from Tropheryma whipplei) or inflammatory disorders (e.g. Crohn's disease) may also present with profound changes in intestinal permeability and protein-losing enteropathy that also require exclusion. Conversely, rare B-cell type lymphomas have also been described even decades following initial

    Eleven patients with an obstructed, fluid-filled uterus, due to carcinoma of the uterus or to its treatment by radiation therapy, were examined with computed tomography (CT) and/or ultrasound. It is important to recognize this abnormality to differentiate it from other causes of pelvic mass and to ensure prompt treatment of pyometra, should it develop. Both CT and ultrasound reliably identified this condition and differentiated it from other pelvic masses.

    Intestinal or cloacal strictures that resulted in intestinal obstruction were diagnosed in six green sea turtles (Chelonia mydas) from three rehabilitation facilities and two zoologic parks. The etiologies of the strictures were unknown in these cases. It is likely that anatomic adaptations of the gastrointestinal tract unique to the green sea turtle's herbivorous diet, paired with causes of reduced intestinal motility, may predispose the species to intestinal damage and subsequent obstructive intestinal disease. In aquarium-maintained green sea turtles, obesity, diet, reduced physical activity, chronic intestinal disease, and inappropriate or inadequate antibiotics might also be potential contributing factors. Clinical, radiographic, and hematologic abnormalities common among most of these sea turtles include the following: positive buoyancy; lethargy; inappetence; regurgitation; obstipation; dilated bowel and accumulation of oral contrast material; anemia; hypoglycemia; hypoalbuminemia; hypocalcemia; and elevated creatine kinase, aspartate aminotransferase, and blood urea nitrogen. Although these abnormalities are nonspecific with many possible contributing factors, intestinal disease, including strictures, should be considered a differential in green sea turtles that demonstrate all or a combination of these clinical findings. Although diagnostic imaging, including radiographs, computed tomography, or magnetic resonance imaging, are important in determining a cause for suspected gastrointestinal disease and identifying an anatomic location of obstruction, intestinal strictures were not successfully identified when using these imaging modalities. Lower gastrointestinal contrast radiography, paired with the use of oral contrast, was useful in identifying the suspected site of intestinal obstruction in two cases. Colonoscopy was instrumental in visually diagnosing intestinal stricture in one case. Therefore, lower gastrointestinal contrast radiography and

    Corynosoma is a parasite that can normally be found in the intestinal tract of fish-eating mammals, particularly in seals and birds. The present case proposed that Corynosoma could attain full maturity in the human intestine. A 70-year-old female complained of abdominal pain. A computed tomography (CT) scan revealed a swelling of the intraperitoneal lymph nodes with no responsible lesion. Video capsule endoscopy and double-balloon endoscopy detected several ulcerations and one parasite in the ileum, which was tightly attached at the bottom of the ulcerations. The parasite was cylindrical and measured approximately 10 mm (long) x 3 mm (wide). Pathologically, the worm had a four-layered body wall and contained embryonated eggs. The sequences of the parasite-derived nuclear ribosomal DNA fragment and mitochondrial DNA fragment of cox1 were almost identical to those of Corynosoma validum. The patient's abdominal pain immediately improved after the administration of pyrantel pamoate (1,500 mg). Corynosoma was possibly the responsible disease in a patient who complained of abdominal pain and in whom no responsible lesion was detected by CT, gastroduodenoscopy or colonoscopy. Examinations of the small intestines should be aggressively performed in such cases.

    Cadmium (Cd), one of the heavy metals, is an important environmental pollutant and a potent toxicant to organism. It poses a severe threat to the growth of the organism, and also has been recognized as a human carcinogen. However, the toxicity of cadmium and its influences on microbiota in mammal's intestine are still unclear. In our experiment, the changes of intestinal microbiota in two groups of mice were investigated, which were supplied with 20 and 100 mg kg(-1) cadmium chloride respectively for 3 weeks. The control group was treated with water free from cadmium chloride only. This study demonstrated that Cd accumulated in some tissues of mice after Cd administration and the gut barrier was impaired. Cd exposure also significantly elevated the colonic level of TNF-α. On the other hand, Cd-treatment could slow down the growth of gut microbiota and reduced the abundance of total intestinal bacteria of the mice. Among them, the growth of Bacteroidetes was significantly suppressed while Firmicutes growth was not. The probiotics including Lactobacillus and Bifidobacterium were notably inhibited. We also observed that the copies of key genes involved in the metabolism of carbohydrates to short-chain fatty acids (SCFAs) were lower in Cd-treated groups than control. As a result, the levels of short-chain fatty acids in colonic decreased significantly. In summary, this study provides valuable insight into the effects of Cd intake on mice gut microbiota.

    The purpose of this study was to investigate the prevalence of house rat zoonotic intestinal parasites from Surabaya District, East Java, Indonesia that have the potential to cause opportunistic infection in humans. House rat fecal samples were collected from an area of Surabaya District with a dense rat population during May 2015. Intestinal parasites were detected microscopically using direct smear of feces stained with Lugol's iodine and modified Ziehl-Neelsen stains. The fecal samples were also cultured for Strongyloides stercoralis. Ninety-eight house rat fecal samples were examined. The potential opportunistic infection parasite densities found in those samples were Strongyloides stercoralis in 53%, Hymenolepis nana in 42%, Cryptosporidium spp in 33%, and Blastocystis spp in 6%. This is the first report of this kind in Surabaya District. Measures need to be taken to control the house rat population in the study area to reduce the risk of the public health problem.

    Abstract The clinical symptoms of pylephlebitis caused by acute appendicitis are varied and atypical, which leads to delayed diagnosis and poor outcomes. Here, we report a case of intestinal necrosis caused by thrombophlebitis of the portomesenteric veins as a complication of acute appendicitis after appendectomy. The patient had acute abdominal pain with tenderness and melena on the 3rd day after appendectomy for the treatment of gangrenous appendicitis. He was diagnosed with intestinal infarction caused by thrombophlebitis of the portomesenteric veins based on enhanced CT and diagnostic abdominal paracentesis. The patient was treated by bowel excision anastomosis and thrombectomy. After postoperative antibiotic and anticoagulation treatments, the patient recovered well and was discharged 22 days after the 2nd operation. A follow-up CT scan showed no recurrence of portomesenteric veins thrombosis 3 months later. Thrombophlebitis of the portomesenteric veins is a rare but fatal complication of acute appendicitis. For all the cases with acute abdominal pain, the possibility of thrombophlebitis should be considered as a differential diagnosis. Once pylephlebitis is suspected, enhanced CT scan is helpful for early diagnosis, and sufficient control of inflammation as well as anticoagulant therapy should be performed. PMID:26091450

    In this study, the role of nitric oxide (NO) in neuronal destruction during acute-phase Trypanosoma cruzi infection was evaluated in male C57BL/6 (WT, wild-type) mice and knockout mice [inducible nitric oxide synthase (iNOS)−/− and interferon (IFN)−/−]. Selected animals were infected by intraperitoneal injection of 100 trypomastigote forms of the Y strain of T. cruzi. Others were injected intraperitoneally with an equal volume of saline solution and served as controls. Our findings support those of previous studies regarding myenteric denervation in acute-phase T. cruzi infection. In addition, we clearly demonstrate that, despite the fact that parasite nests and similar inflammatory infiltrate in the intestinal wall were more pronounced in infected iNOS−/− mice than in infected WT mice, the former presented no reduction in myenteric plexus neuron numbers. Neuronal nerve profile expression, as revealed by the general nerve marker PGP 9.5, was preserved in all knockout animals. Infected IFN−/− mice suffered no significant neuronal loss and there was no inflammatory infiltrate in the intestinal wall. On days 5 and 10 after infection, iNOS activity was greater in infected WT mice than in controls, whereas iNOS activity in infected knockout mice remained unchanged. These findings clearly demonstrate that neuronal damage does not occur in NO-impaired infected knockout mice, regardless of whether inflammatory infiltrate is present (iNOS−/−) or absent (IFN−/−). In conclusion, our observations strongly indicate that myenteric denervation in acute-phase T. cruzi infection is because of IFN-γ-elicited NO production resulting from iNOS activation in the inflammatory foci along the intestinal wall.

    Gas content and transit appear to conspire with the motor and sensory responses of the gut to produce gas related symptoms, both in normal individuals and especially in patients with irritable bowel syndrome (IBS). In relation to gas in IBS, two questions need to be addressed: do IBS patients produce more gas and what are the relationships between intestinal gas and symptoms? The balance of evidence seems to indicate that distension is a real phenomenon in IBS and that such distension accurately reflects gas content. More problematic is extrapolation of the observations relating symptoms to gas transit and retention.

    Atrioventricular septal defects represent a class of congenital cardiac malformations that vary in presentation and management strategy depending upon the severity of the particular lesions present. We present the case of a premature neonate who had a partial atrioventricular septal defect and an accessory mitral (or left atrioventricular) valve leaflet. The latter caused severe left ventricular outflow tract obstruction and severely depressed left ventricular function. We found only one other report of this atrioventricular valve abnormality in association with atrioventricular septal defect. To our knowledge, our patient (at a body weight of 1,800 g) is the smallest to survive corrective surgery of an accessory mitral valve leaflet with severe left ventricular outflow tract obstruction. In addition to our patient's case, we discuss the relevant medical literature. PMID:28100980

    Familial multiple intestinal atresias is an autosomal recessive disease with or without combined immunodeficiency. In the last year, several reports have described mutations in the gene TTC7A as causal to the disease in different populations. However, exact correlation between different genotypes and various phenotypes are not clear. In this study, we report identification of novel compound heterozygous mutations in TTC7A gene in a Malay girl with familial multiple intestinal atresias and severe combined immunodeficiency (MIA-SCID) by whole exome sequencing. We found two mutations in TTC7A: one that destroyed a putative splicing acceptor at the junction of intron 17/exon 18 and one that introduced a stop codon that would truncate the last two amino acids of the encoded protein. Reviewing the recent reports on TTC7A mutations reveals correlation between the position and nature of the mutations with patient survival and clinical manifestations. Examination of public databases also suggests carrier status for healthy individuals, making a case for population screening on this gene, especially in populations with suspected frequent founder mutations.

    Unilateral ureteral obstruction (UUO) is the most widely used animal model of progressive renal disease. Although renal interstitial fibrosis is commonly used as an end point, recent studies reveal that obstructive injury to the glomerulotubular junction leads to the formation of atubular glomeruli. To quantitate the effects of UUO on the remainder of the nephron, renal tubular and interstitial responses were characterized in mice 7 and 14 days after UUO or sham operation under anesthesia. Fractional proximal tubular mass, cell proliferation, and cell death were measured by morphometry. Superoxide formation was identified by nitro blue tetrazolium, and oxidant injury was localized by 4-hydroxynonenol and 8-hydroxydeoxyguanosine. Fractional areas of renal vasculature, interstitial collagen, α-smooth muscle actin, and fibronectin were also measured. After 14 days of UUO, the obstructed kidney loses 19% of parenchymal mass, with a 65% reduction in proximal tubular mass. Superoxide formation is localized to proximal tubules, which undergo oxidant injury, apoptosis, necrosis, and autophagy, with widespread mitochondrial loss, resulting in tubular collapse. In contrast, mitosis and apoptosis increase in dilated collecting ducts, which remain patent through epithelial cell remodeling. Relative vascular volume fraction does not change, and interstitial matrix components do not exceed 15% of total volume fraction of the obstructed kidney. These unique proximal and distal nephron cellular responses reflect differential "fight-or-flight" responses to obstructive injury and provide earlier indexes of renal injury than do interstitial compartment responses. Therapies to prevent or retard progression of renal disease should include targeting proximal tubule injury as well as interstitial fibrosis.

    2014-01-01

    Clostridium perfringens causes enteritis and enterotoxemia in humans and livestock due to prolific toxin production. In broth culture, C. perfringens uses the Agr-like quorum sensing (QS) system to regulate production of toxins important for enteritis/enterotoxemia, including beta toxin (CPB), enterotoxin, and epsilon toxin (ETX). The VirS/VirR two-component regulatory system (TCRS) also controls CPB production in broth cultures. Both the Agr-like QS and VirS/VirR systems are important when C. perfringens senses enterocyte-like Caco-2 cells and responds by upregulating CPB production; however, only the Agr-like QS system is needed for host cell-induced ETX production. These in vitro observations have pathophysiologic relevance since both the VirS/VirR and Agr-like QS signaling systems are required for C. perfringens strain CN3685 to produce CPB in vivo and to cause enteritis or enterotoxemia. Thus, apparently upon sensing its presence in the intestines, C. perfringens utilizes QS and TCRS signaling to produce toxins necessary for intestinal virulence. PMID:24061146

    Small bowel obstruction (SBO) is a common condition encountered in surgical practice. Literature shows divers and many different etiologies for intestinal obstruction. However, bezoars are rarely reported as an etiological factor. A bezoar happens most commonly in patients with impaired gastrointestinal motility. There are four types of bezoars: phytobezoars, trichobezoars, pharmacobezoars and lactobezoars. The most common type is phytobezoars, which are composed of undigested fiber from vegetables or fruits especially persimmons. They are mostly composed of cellulose, tannin and lignin. The commonest phytobezoar reported worldwide is related to the persimmon fruit ingestion. The most common symptom of bezoar-induced SBO is abdominal pain (96–100%). Other common symptoms include nausea and vomiting. Primary small bowel phytobezoars almost always present as SBO. We present an unusual case of SBO caused by a phytobezoar in a 35-year-old patient. Many types of bezoar can be removed endoscopically, but some will require operative intervention. PMID:28031856

    Crohn's disease (CD) is an autoimmune disease, which may cause obstructing intestinal strictures due to inflammation, fibrosis (deposition of collagen), or a combination of both. Identifying the different stages of the disease progression is still challenging. In this work, we indicated the feasibility of non-invasively characterizing intestinal strictures using photoacoustic imaging (PAI), utilizing the uniquely optical absorption of hemoglobin and collagen. Surgically removed human intestinal stricture specimens were investigated with a prototype PAI system. 2D PA images with acoustic resolution at wavelength 532, 1210 and 1310 nm were formulated, and furthermore, the PA histochemical components images which show the microscopic distributions of histochemical components were solved. Imaging experiments on surgically removed human intestinal specimens has demonstrated the solved PA images were significantly different associated with the presence of fibrosis, which could be applied to characterize the intestinal strictures for given specimens.

    Intestinal mucosal immune components and mRNA levels of inflammatory cytokines, tight junction proteins, antioxidant enzymes and related signalling molecules in young grass carp (Ctenopharyngodon idellus) under dietary manganese (Mn) deficiency or excess were investigated. Fish were fed the diets containing graded levels of Mn [3.65-27.86 mg Mn kg(-1) diet] for 8 weeks. The results demonstrated that Mn deficiency significantly decreased the lysozyme and acid phosphatase (ACP) activities, up-regulated tumour necrosis factor α (TNF-α), interleukin 8 and the signalling factor nuclear factor-κB p65, and down-regulated interleukin 10 (IL-10), transforming growth factor β1, inhibitor of signalling factors κB-α and target of rapamycin mRNA levels in the proximal intestine (PI), mid intestine (MI) and distal intestine (DI). However, Mn deficiency did not change the C3 content in the PI, whereas it decreased the C3 contents in the MI and DI. Additionally, Mn depletion also resulted in significantly low mRNA levels for tight junction proteins (claudin-b, claudin-c, claudin-15, occludin and zonula occludens-1), antioxidant enzymes (MnSOD, GPx and CAT) and NF-E2-related factor-2 in the intestines of fish. Excessive Mn exhibited toxic effects similar to Mn deficiency, where optimal Mn contents reversed those indicators. In conclusion, Mn deficiency or excess causes the depression of intestinal immunity, induction of inflammation and dysfunction of the intestinal physical barrier relating to NF-κB, TOR and Nrf2 signalling in grass carp. Furthermore, quadratic regression analysis at 95% maximum response of lysozyme and acid phosphatase activities in the distal intestine of young grass carp revealed the optimum dietary Mn levels to be 8.90 and 8.99 mg kg(-1) diet, respectively.

    Alcohol and dietary fat both play an important role in alcohol-mediated multi-organ pathology, including gut and liver. In the present study we hypothesized that the combination of alcohol and dietary unsaturated fat (USF) would result in intestinal inflammatory stress and mucus layer alterations, thus contributing to disruption of intestinal barrier integrity. C57BL/6N mice were fed Lieber-DeCarli liquid diets containing EtOH and enriched in USF (corn oil/linoleic acid) or SF (medium chain triglycerides: beef tallow) for 8 weeks. Intestinal histology, morphometry, markers of inflammation, as well as levels of mucus protective factors were evaluated. Alcohol and dietary USF triggered an intestinal pro-inflammatory response, characterized by increase in Tnf-α, MCP1, and MPO activity. Further, alcohol and dietary USF, but not SF, resulted in alterations of the intestinal mucus layer, characterized by decreased expression of Muc2 in the ileum. A strong correlation was observed between down-regulation of the antimicrobial factor Cramp and increased Tnf-α mRNA. Therefore, dietary unsaturated fat (corn oil/LA enriched) is a significant contributing factor to EtOH-mediated intestinal inflammatory response and mucus layer alterations in rodents.

  20. An unusual cause of chronic abdominal pain after laparoscopic Roux en Y gastric bypass: Case report of a penetrating fish bone causing adhesions at the biliary-digestive junction resulting in partial obstruction and chronic symptoms

    Background The management of chronic abdominal pain after laparoscopic Roux-en-Y gastric bypass (LRYGP) is complex and challenging. Foreign body intestinal perforation including that caused by fish bones has previously been reported in the literature and if clinically unrecognized, can cause significant morbidity and mortality. Fish bone perforation as a cause of chronic abdominal pain after LRYGP has rarely been reported. Summary The unusual case of a 54 year old female presenting with recurrent episodes of postprandial pain 2 years after LRYGP is reported. Previous radiological and endoscopic investigations did not reveal any abnormality and after the most recent clinical presentation, a laparoscopic exploration was performed. A protruding fish bone at the biliary-digestive junction was discovered intra-operatively and successfully extracted. Dense adhesions between the involved intestinal loops were lysed in an attempt to improve intestinal transit and subsequently relieve post-prandial pain. Conclusion This case highlights the possibility of a missed fish bone perforation causing chronic postprandial abdominal pain and discomfort in a patient with a Roux-en-Y gastric bypass anatomy. Foreign body perforation is a rare cause of abdominal pain after gastric bypass that should be considered when evaluating chronic abdominal pain symptoms after LRYGP. PMID:27107305

  1. Decision Making in Bowel Obstruction: A Review

    PubMed Central

    2016-01-01

    Over the last century there have not been significant changes in the anatomical location of obstruction. The age of presentation has increased along with age related co-morbidity. Management has consequently been challenging as risks keep on increasing with advanced age. Hence, clear decision making has become essential in its management. A selective review of the literature pertaining to common age related aetiologies, diagnosis methods leading to standard decision making and treatment of acute intestinal obstruction was done. The same is obtained from randomized controlled studies, meta-analysis and other related evidence based publications. Predicting the conservative or operative management of Bowel Obstruction (BO) is difficult. BO in young age, in unscarred abdomen and Large Bowel Obstruction (LBO) needs early surgery. Decision on surgery should be taken in paediatric patient by second day and preferably between 3-5 days of admission in adults. Higher American Society of Anaesthesiologists (ASA) grade correlates well with the mortalities. In this article, the timing of surgery, methods to avoid bowel resection and type of surgery in various causes are stressfully analysed and discussed. PMID:28050445

    A gallstone ileus is an unusual form of bowel obstruction. Colonic gallstone ileus is rare, difficult to diagnose, and still has a high mortality rate. We present a case of biliary ileus caused by an impacted gallstone, causing necrosis and perforation of the rectosigmoid junction. A Hartmann's procedure was performed to treat the perforation and the obstruction. Cholecystectomy and closure of the cholecysto-colonic fistula were delayed until restoration of the intestinal continuity.

    Intestinal lymphangiectasia (IL) is a rare disease characterized by dilatation of intestinal lymphatics. It can be classified as primary or secondary according to the underlying etiology. The clinical presentations of IL are pitting edema, chylous ascites, pleural effusion, acute appendicitis, diarrhea, lymphocytopenia, malabsorption, and intestinal obstruction. The diagnosis is made by intestinal endoscopy and biopsies. Dietary modification is the mainstay in the management of IL with a variable response. Here we report 2 patients with IL in Bahrain who showed positive response to dietary modification. PMID:26837404

    Three case histories of nursing infants suffering from different forms of intestinal problems, who underwent special dietary therapy in order to solve situations that would be difficult to deal with using the special artificial milk varieties on the market, are presented. These children were administered a homemade food consisting ofParmigiano Reggiano cheese seasoned for at least 36 months, rice or maize custard and tapioca, sugar, maize oil. In the first case the diagnosis of "widespread nonspecific acute colitis" was made compatible with "antibiotic-associated colitis" and Clostridium difficile was isolated from the feces. The second case, under the suspicion of cow's milk allergy, was fed by soya and hydrolyzed milk with persitent disturbed alvus with greenish feces and mucus. The third case was represented by a nursing child with persistent diarrhoic alvus after an acute episode with subsequent intolerance to rice milk. After the introduction of the food based on Parmigiano Reggiano cheese, all cases showed a rapid and progressive improvement of symptoms and alvus characteristics and were discharged with increased weight. The Parmigiano Reggiano cheese shows a high concentration of easily absorbed amino acids and oligopeptides like a hydrolyzed proteic preparation. As regards the lipoid component the medium and short chain fatty acids are directly absorbed in the bowel and immediately usable as a significant source of energy. Finally, another relevant characteristic of Parmigiano Reggiano cheese is the complete absence of lactose. The use of Parmigiano Reggiano cheese as a dietary therapy is appropriate not only for its high nutritional value, but also for its characteristics as a functional food that produces beneficial effects on health with regards to the gastrointestinal tract and the inflammatory problems resulting from alimentary intolerance, post-therapeutic antibiotic dismicrobism, or post-infective conditions. Moreover, its efficay on these pathologic

    Tight junctions (TJs) play an important role in maintaining the mucosal barrier function and gastrointestinal health of animals. Lactobacillus plantarum (L. plantarum) was reported to protect the intestinal barrier function of early-weaned piglets against enterotoxigenic Escherichia coli (ETEC) K88 challenge; however, the underlying cellular mechanism of this protection was unclear. Here, an established intestinal porcine epithelia cell (IPEC-J2) model was used to investigate the protective effects and related mechanisms of L. plantarum on epithelial barrier damages induced by ETEC K88. Epithelial permeability, expression of inflammatory cytokines, and abundance of TJ proteins, were determined. Pre-treatment with L. plantarum for 6h prevented the reduction in transepithelial electrical resistance (TEER) (P<0.05), inhibited the increased transcript abundances of interleukin-8 (IL-8) and tumor necrosis factor (TNF-α) (P<0.05), decreased expression of claudin-1, occludin and zonula occludens (ZO-1) (P<0.05) and protein expression of occludin (P<0.05) of IPEC-J2 cells caused by ETEC K88. Moreover, the mRNA expression of negative regulators of toll-like receptors (TLRs) [single Ig Il-1-related receptor (SIGIRR), B-cell CLL/lymphoma 3 (Bcl3), and mitogen-activated protein kinase phosphatase-1 (MKP-1)] in IPEC-J2 cells pre-treated with L. plantarum were higher (P<0.05) compared with those in cells just exposed to K88. Furthermore, L. plantarum was shown to regulate proteins of nuclear factor κB (NF-κB) and mitogen-activated protein kinase (MAPK) signaling pathways. These results indicated that L. plantarum may improve epithelial barrier function by maintenance of TEER, inhibiting the reduction of TJ proteins, and reducing the expression of proinflammatory cytokines induced by ETEC K88, possibly through modulation of TLRs, NF-κB and MAPK pathways.

    Background and Purpose Monoglyceride lipase (MGL) degrades 2-arachidonoyl glycerol (2-AG), an endogenous agonist of cannabinoid receptors (CB1/2). Because the CB1 receptor is involved in the control of gut function, we investigated the effects of pharmacological inhibition and genetic deletion of MGL on intestinal motility. Furthermore, we determined whether defective 2-AG degradation affects μ-opioid receptor (μ receptor) signalling, a parallel pathway regulating gut motility. Experimental Approach Gut motility was investigated by monitoring Evans Blue transit and colonic bead propulsion in response to MGL inhibition and CB1 receptor or μ receptor stimulation. Ileal contractility was investigated by electrical field stimulation. CB1 receptor expression in ileum and colon was assessed by immunohistochemical analyses. Key Results Pharmacological inhibition of MGL slowed down whole gut transit in a CB1 receptor-dependent manner. Conversely, genetic deletion of MGL did not affect gut transit despite increased 2-AG levels. Notably, MGL deficiency caused complete insensitivity to CB1 receptor agonist-mediated inhibition of whole gut transit and ileal contractility suggesting local desensitization of CB1 receptors. Accordingly, immunohistochemical analyses of myenteric ganglia of MGL-deficient mice revealed that CB1 receptors were trapped in endocytic vesicles. Finally, MGL-deficient mice displayed accelerated colonic propulsion and were hypersensitive to μ receptor agonist-mediated inhibition of colonic motility. This phenotype was reproduced by chronic pharmacological inhibition of MGL. Conclusion and Implications Constantly elevated 2-AG levels induce severe desensitization of intestinal CB1 receptors and increased sensitivity to μ receptor-mediated inhibition of colonic motility. These changes should be considered when cannabinoid-based drugs are used in the therapy of gastrointestinal diseases. PMID:26075589

    Introduction The colostomy is often necessary in complicated divertcular disease. The laparoscopic colostomy is not widely used for the treatment of complicated diverticular disease. Its use in patients with high operative risk is still on debate. The aim of this case report was to present the benefits of laparoscopic colostomy in patients with high peri-and postoperative risk factors. Presentation of case We present a case of 76-year-old female admitted to emergency unit for left colonic obstruction. The patient had a past history of liver cirrhosis HCV-related with a severe malnutrition, hypertrophic cardiomyopathy, diverticular disease, hiatal ernia, previous appendectomy. Patient was classified according to their preoperative risk ASA 3 (classification of the American society of Anestesia-ASA score). Contrast-enhanced abdominal CT revealed a marked thickening in the sigmoid colon and a marked circumferential stenosis in the sigmoid colon in absence of neoplasm, and/or abscess. The laparoscopic procedure is proposed as first intention. Discussion The operation time was 50 min, and the hospital stay was 4 days. Post operative complications grade I according to the Clavien Dindo Classification. Conclusions Laparoscopic colostomy is safe and feasible procedure in experienced hands. It is associated with low morbidity and short stay in hospital and should be considered a good alternative to a laparotomy. PMID:26036456

    Changes in small intestinal morphology (jejunum) were examined at 28 d of age in chicks fed with full-fat sunflower kernels (FFSK)-based diets. Jejunal mucosa of chicks (six chicks per treatment) were embedded in Epon-812 for examination by a conventional electron microscope procedure. A portion of the tissues was also sectioned and embedded in paraffin for examination by light microscopy. Brush border, goblet cells, and intraepithelial lymphocytes, on the one hand, and fibroblast and mononuclear cells (lymphocytes, plasma cells, macrophages) were observed in the enterocytes and lamina propria, respectively. The results showed that the birds fed 150 g kg(-1) of FFSK showed a shortening and thickening of the villi, hyperplasia and vacuolar degeneration of enterocytes, and hypertrophy and hyperplasia of goblet cells. Likewise, an increment of intraepithelial lymphoid cells and hypercellularity of the lamina propria was observed. In addition, electron microscopy showed large vacuoles in the enterocytes, which could be dilations of agranular and granular endoplasmic reticulum or Golgi. There were many dark granules within the vacuoles that could be triglyceride-rich lipoproteins (portomicrons). These lesions could have been due to the presence of chlorogenic acid or to the greater concentration of oil in the FFSK diet. Our observations demonstrated that addition of 150 g kg(-1) FFSK to broiler chicken diets caused alterations in jejunal mucosa that could explain the decrease in fat digestibility observed in a previous experiment in which we incorporated FFSK into broiler diets.

    Recent research indicates that suicide rates are elevated in those living at higher altitudes in both the United States and South Korea. A possible mechanism that was proposed is metabolic stress associated with hypoxia. This commentary discusses these results, and also the association between elevated suicide rates and other conditions associated with hypoxia (smoking, chronic obstructive pulmonary disease and asthma). Tryptophan hydroxylase may not normally be saturated with oxygen, so mild hypoxia would decrease serotonin synthesis. Low brain serotonin is known to be associated with suicide. Thus, the commentary proposes and discusses the hypothesis that decreased brain serotonin synthesis associated with hypoxia is a mechanism that may contribute to suicide in conditions causing hypoxia. Finally the commentary proposes various studies that could test aspects of this hypothesis.

    Introduction: This study aimed to evaluate urination frequency among patients with obstructive sleep apnea syndrome (OSAS) and the effect of continuous positive airway pressure (CPAP) treatment. Methods: We evaluated 138 men with moderate-to-severe OSAS by using polysomnography. Urination status was assessed at baseline and three months using the International Prostate Symptom Score and Overactive Bladder Symptom Score. Nocturia was defined as ≥2 nighttime urinations and patients were classified into Group A (<50 years old with nocturia), Group B (≥50 years old with nocturia), and Group C (patients without nocturia). OSAS severity and other urinary symptoms were also evaluated. Results: Patients with nocturia exhibited more severe OSAS, compared to patients without nocturia (apnea-hypopnea index [AHI]: 52.0 vs. 44.7; p=0.021). Group A had the worst AHI, but did not have additional voiding symptoms, compared to Group B (p<0.001). The number of urinations was significantly correlated with OSAS severity in <50-year-old patients (p=0.013). CPAP reduced the number of urinations in Group A (75% of patients) and Group B (90% of patients). Patients with and without improved nocturia exhibited significant differences in their baseline OSAS severity (AHI: 53.7 vs. 37.3; p=0.042). Conclusions: OSAS severity was associated with the number of urinations in <50-year-old patients. CPAP decreased the nocturia frequency in 85% of patients with nocturia and was most effective in patients with severe AHI. However, additional studies should evaluate voiding volume in order to elucidate the mechanism of nocturia in patients with OSAS. PMID:28255415

    Introduction The gastrointestinal tract is frequently exposed to noxious stimuli that may cause oxidative stress, inflammation and injury. Intraluminal pro-oxidants from ingested nutrients especially iron salts and ascorbic acid frequently consumed together, can lead to catalytic formation of oxygen-derived free radicals that ultimately overwhelm the cellular antioxidant defense and lead to cell damage. Hypothesis Since the mechanisms remain sketchy, efforts have been exerted to evaluate the role of epigenetics in modulating components of endogenous enzymatic antioxidants in the intestine. To this end, Caco-2/15 cells were exposed to the iron-ascorbate oxygen radical-generating system. Results Fe/Asc induced a significant increase in lipid peroxidation as reflected by the elevated formation of malondialdehyde along with the alteration of antioxidant defense as evidenced by raised superoxide dismutase 2 (SOD2) and diminished glutathione peroxidase (GPx) activities and genes. Consequently, there was an up-regulation of inflammatory processes illustrated by the activation of NF-κB transcription factor, the higher production of interleukin-6 and cycloxygenase-2 as well as the decrease of IκB. Assessment of promoter’s methylation revealed decreased levels for SOD2 and increased degree for GPx2. On the other hand, pre-incubation of Caco-2/15 cells with 5-Aza-2′-deoxycytidine, a demethylating agent, or Trolox antioxidant normalized the activities of SOD2 and GPx, reduced lipid peroxidation and prevented inflammation. Conclusion Redox and inflammatory modifications in response to Fe/Asc -mediated lipid peroxidation may implicate epigenetic methylation. PMID:23717425

    Matriptase is an epithelial-derived type-II transmembrane serine protease. This protease is expressed prominently in the villus tip of small-intestinal epithelia at which senescent cells undergo shedding and/or apoptosis. The basement membrane of epithelial cells, including small-intestinal epithelial cells, contains extracellular matrix (ECM) proteins such as fibronectin and laminin. We found previously that high concentrations of a recombinant matriptase catalytic domain (r-MatCD) (e.g. 1 μM) caused an increased detachment of and increases in the activity of apoptotic effector caspase-3 in a rat small-intestinal epithelial IEC-6 line cultured on laminin-coated plates and proposed that at sites with its high level of expression, matriptase contributes to promoting shedding and/or detachment-induced death of epithelial cells through a mechanism mediating loss of cell-ECM adhesion. In this study, we found that even without increasing cell detachment, a high concentration of r-MatCD causes an increase in caspase-3 activity in IEC-6 cells cultured on fibronectin-coated plates, suggesting that the recombinant matriptase can cause apoptosis by a mechanism unrelated to cell detachment. Also, r-MatCD-treated IEC-6 cells on fibronectin were found to display spindle-like morphological changes. We suggest that r-MatCD causes apoptosis of IEC-6 on fibronectin by a mechanism involving the disruption of cell integrity.

    Background Intestinal obstruction is a poorly recognized and probably underreported complication of strongyloidiasis. We present herein an unusual case, of complete duodenal obstruction caused by S. stercoralis. Methods A systematic review of the literature examining the clinical course, diagnostic methods, and outcome of this rare complication of strongyloidiasis was performed. Results A 42-year-old woman presented with a 5-month history of abdominal pain, vomit, and weight loss. An abdominal CT scan showed an obstruction of the third part of the duodenum. Segmental intestinal resection was carried out and histopathology examination revealed heavy Strongyloides stercoralis infestation. Duodenal obstruction is a rare complication of S. stercoralis infection, with only 8 cases described in the literature since 1970. Most of the patients are males, middle-aged, and the diagnosis was made by duodenal aspirate/biopsy, or analysis of surgical specimen. Conclusions Duodenal obstruction is an unusual, but potential fatal, complication of S. stercoralis infection. The large spectrum of clinical manifestation and lack of classic clinical syndrome make the final diagnosis of strongyloidiasis extremely difficult. A high index of suspicion, mainly in patients from endemic areas, is needed for correct and early diagnosis of this uncommon presentation of Strogyloides stercoralis enteritis. PMID:20698992

    Choroid plexus cysts are common and typically asymptomatic abnormal folds of the epithelial lining of the choroid plexus. Rarely, these cysts may gradually enlarge and cause outflow obstruction of cerebrospinal fluid. The authors present a case of a large choroid plexus cyst causing acute hydrocephalus in a previously healthy 2-year-old boy. The patient presented with markedly declining mental status, vomiting, and bradycardia over the course of several hours. Computed tomography scans demonstrated enlarged lateral and third ventricles with sulcal effacement, but no obvious mass lesions or hemorrhage. There was no antecedent illness or trauma. A right frontal external ventricular drain was placed in the patient, resulting in decompression of only the right lateral ventricle. Magnetic resonance (MR) imaging demonstrated a lobulated cyst arising from the choroid plexus of the left lateral ventricle and herniating through the foramen of Monro into the third ventricle, occluding both the foramen of Monro and the cerebral aqueduct. The patient underwent an endoscopic fenestration of the cyst, and histological results confirmed that it was a choroid plexus cyst. Postoperative MR imaging showed a marked reduction in the cyst size. The cyst was no longer in the third ventricle, the foramen of Monro and the aqueduct were patent, and the ventricles were decompressed. The patient was discharged home with no deficits. To the authors' knowledge, there are no previous reports of a choroid plexus cyst causing acute hydrocephalus due to herniation into the third ventricle. This case is illustrative because it describes this entity for the first time, and more importantly highlights the need to obtain a diagnosis when a patient presents with acute hydrocephalus without a clear cause.

    Many of the symptoms of Gulf War Illness (GWI) that include neurological abnormalities, neuroinflammation, chronic fatigue and gastrointestinal disturbances have been traced to Gulf War chemical exposure. Though the association and subsequent evidences are strong, the mechanisms that connect exposure to intestinal and neurological abnormalities remain unclear. Using an established rodent model of Gulf War Illness, we show that chemical exposure caused significant dysbiosis in the gut that included increased abundance of phylum Firmicutes and Tenericutes, and decreased abundance of Bacteroidetes. Several gram negative bacterial genera were enriched in the GWI-model that included Allobaculum sp. Altered microbiome caused significant decrease in tight junction protein Occludin with a concomitant increase in Claudin-2, a signature of a leaky gut. Resultant leaching of gut caused portal endotoxemia that led to upregulation of toll like receptor 4 (TLR4) activation in the small intestine and the brain. TLR4 knock out mice and mice that had gut decontamination showed significant decrease in tyrosine nitration and inflammatory mediators IL1β and MCP-1 in both the small intestine and frontal cortex. These events signified that gut dysbiosis with simultaneous leaky gut and systemic endotoxemia-induced TLR4 activation contributes to GW chemical-induced neuroinflammation and gastrointestinal disturbances.

    Many of the symptoms of Gulf War Illness (GWI) that include neurological abnormalities, neuroinflammation, chronic fatigue and gastrointestinal disturbances have been traced to Gulf War chemical exposure. Though the association and subsequent evidences are strong, the mechanisms that connect exposure to intestinal and neurological abnormalities remain unclear. Using an established rodent model of Gulf War Illness, we show that chemical exposure caused significant dysbiosis in the gut that included increased abundance of phylum Firmicutes and Tenericutes, and decreased abundance of Bacteroidetes. Several gram negative bacterial genera were enriched in the GWI-model that included Allobaculum sp. Altered microbiome caused significant decrease in tight junction protein Occludin with a concomitant increase in Claudin-2, a signature of a leaky gut. Resultant leaching of gut caused portal endotoxemia that led to upregulation of toll like receptor 4 (TLR4) activation in the small intestine and the brain. TLR4 knock out mice and mice that had gut decontamination showed significant decrease in tyrosine nitration and inflammatory mediators IL1β and MCP-1 in both the small intestine and frontal cortex. These events signified that gut dysbiosis with simultaneous leaky gut and systemic endotoxemia-induced TLR4 activation contributes to GW chemical-induced neuroinflammation and gastrointestinal disturbances.

    Obstructive jaundice as a presentation of abdominal tumors in childhood is extremely rare. To date, only 4 cases of neuroblastoma causing obstructive jaundice at diagnosis have been reported in children. We report a 4-year-old boy who presented to the emergency department with abdominal pain, jaundice, choluria and acholia. A diagnosis of unresectable, nonmetastatic neuroblastoma was made. Chemotherapy reduced the size of the tumor and relieved the symptoms of obstructive jaundice without the need for decompressive surgery. Abdominal tumors should be included in the differential diagnoses of obstructive jaundice in childhood.

    Previous studies showed that Clostridium perfringens type D animal disease strain CN3718 uses NanI sialidase for adhering to enterocyte-like Caco-2 cells. The current study analyzed whether NanI is similarly important when type A and C human intestinal disease strains attach to Caco-2 cells. A PCR survey determined that the nanI gene was absent from typical type A food poisoning (FP) strains carrying a chromosomal enterotoxin (CPE) gene or the genetically related type C Darmbrand (Db) strains. However, the nanI gene was present in type A strains from healthy humans, type A strains causing CPE-associated antibiotic-associated diarrhea (AAD) or sporadic diarrhea (SD), and type C Pig-Bel strains. Consistent with NanI sialidase being the major C. perfringens sialidase when produced, FP and Db strains had little supernatant sialidase activity compared to other type A or C human intestinal strains. All type A and C human intestinal strains bound to Caco-2 cells, but NanI-producing strains had higher attachment levels. When produced, NanI can contribute to host cell attachment of human intestinal disease strains, since a nanI null mutant constructed in type A SD strain F4969 had lower Caco-2 cell adhesion than wild-type F4969 or a complemented strain. Further supporting a role for NanI in host cell attachment, sialidase inhibitors reduced F4969 adhesion to Caco-2 cells. Collectively, these results suggest that NanI may contribute to the intestinal attachment and colonization needed for the chronic diarrhea of CPE-associated AAD and SD, but this sialidase appears to be dispensable for the acute pathogenesis of type A FP or type C enteritis necroticans.

    "Obstructive uropathy" is a generic term which combines different diseases in infants and childhood. Both the upper and lower urinary tract may be affected. Diseases of the urinary tract can cause an intrinsic obstruction. Sometimes tumours may cause a compression and as secondary effect an obstruction (extrinsic). Ultrasound is the key diagnostic tool and shows dilatation of the obstructed urinary tract. But for the functional exploration of babies and toddlers, renal scanning and X-ray examinations are necessary. These examinations lead to an exposure to radiation which necessitates careful indication. Some of the congenital diseases (for example ureteropelvic junction obstruction, megaureter) show a maturation without any intervention. So one has to decide whether to wait and see or to operate. A percutaneous nephrostomy or a DJ-catheter is not often used in the treatment of obstruction in general. These forms of drainage are more often used in the treatment of stones or of extrinsic obstruction. A pyelocutaneostomy or ureterocutaneostomy is a special surgical procedure in pediatric urology for transient drainage of the upper urinary tract (megaureter). The operation of a seriously ill new-born should be done in a centre for pediatric urology and pediatric nephrology. When the upper urinary tract is dilated, patients may need an antibiotic prophylaxis, because the dilatation of the upper urinary tract increases the risk of urinary tract infections (UTI). The indication for antibiotic prophylaxis should by guided by the criteria of the APN-Consensus Paper. Long-term follow-up is necessary and should comprise ultrasound, physical examination, controlling the blood pressure, urine analysis and blood tests. The aims of diagnostics, treatment and long-term follow-up are the preservation of renal function and to protect the children from UTI. This goal must be reached under conditions that are appropriate for children and their parents.

    Extrahepatic portal vein obstruction, although rare in children, is a significant cause of portal hypertension (PHT) leading to life-threatening gastrointestinal bleeding in the pediatric age group. PHT may also lead to other complications such as hyperesplenism, cholangyopathy, ascites, and even hepatopulmonary syndrome and portopulmonary hypertension that may require organ transplantation. Herein we report the case of an asymptomatic 11-month-old infant wherein a hepatomegaly and cavernous transformation of the portal vein was detected by liver ultrasound. Neither signs of thrombosis in arteriovenous system, nor affectation of biliary tract were identified in the magnetic resonance imaging study. A significant enlargement of the caudate lobe of the liver was reported. No risk factors were detected. The differential diagnosis performed was extensive. Inherited thrombophilia and storage disorders were especially considered. Liver biopsy was normal. Upper gastrointestinal esophagogastroduodenoscopy detected two small varicose cords on the distal third of the esophagus. Finding a cavernous transformation of the portal vein with evidence of collateral circulation in such an early age is a challenging condition for professionals, since PHT may lead to severe complications during childhood and can compromise growth and development. Evidence-based guidelines for the management of PHT in adults have been published. However, follow-up and treatment of pediatric patients have not yet been standardized. Moreover, management of PHT in infants faces particular difficulties such as technical restrictions that could hinder their treatment. PMID:27504083

    Alveolar macrophages produce neutrophil chemoattractants; this cellular cross-talk contributes to neutrophilic airway inflammation in chronic obstructive pulmonary disease (COPD). We have investigated the chemotaxis cross-talk mechanisms between these cells using COPD alveolar macrophages. Using conditioned media from stimulated COPD alveolar macrophages, we investigated the relative contributions of growth-related oncogene (CXCL1), interleukin-8 (CXCL8), and regulated on activation normal T cell expressed and secreted (CCL5) to neutrophil chemotaxis and evaluated the effect of blocking the chemokine receptors CXCR1 and CXCR2 on chemotaxis caused by macrophage-conditioned media. Furthermore, we evaluated whether corticosteroid treatment of stimulated alveolar macrophages inhibited the chemotaxis ability of conditioned media. Alveolar macrophages isolated from COPD (n = 8) and smoker (S) (n = 8) lungs were treated with ultra-pure lipopolysaccharide in the presence and absence of dexamethasone (1 μM). Supernatants were used for neutrophil chemotaxis assays. SB656933 (2-hydroxy-N,N-dimethyl-3-{2-[[(R)-1-(5-methyl-furan-2-yl)-propyl]amino]-3,4-dioxo-cyclobut-1-enylamino}-benzamide) (CXCR2 antagonist) and Sch527123 [1-(2-chloro-3-fluorophenyl)-3-(4-chloro-2-hydroxy-3-piperazin-1-ylsulfonylphenyl)urea, 3-(2-chloro-3-fluoro-phenyl)-1-(4-chloro-2-hydroxy-3-piperazin-1-ylsulfonyl-phenyl)urea] (dual CXCR1 and CXCR2 antagonist) and blocking antibodies for CXCL8, CXCL1, and CCL5 were assessed. Conditioned media caused neutrophil chemotaxis in COPD and smokers (60.5 and 79.9% of total cells, respectively). Dexamethasone did not significantly reduce neutrophil chemotaxis in COPD or S. SB656933 and Sch527123 inhibited chemotaxis in a concentration-dependent manner, with the dual antagonist Sch527123 causing greater inhibition of chemotaxis. CXCL8 antibody inhibited neutrophil chemotaxis to basal levels, although there was no significant effect of blocking either CXCL1 or CCL5 (P

    Context. Colonic complications associated with acute pancreatitis have a low incidence but carry an increased risk of mortality with delayed diagnosis and treatment. Pancreatic colonic fistula is most commonly associated with walled off pancreatic necrosis or abscess formation and rarely forms spontaneously. Classic clinical manifestations for pancreatic colonic fistula include diarrhea, hematochezia, and fever. Uncommonly pancreatic colonic fistula presents as large bowel obstruction. Case. We report a case of a woman with a history of recurrent episodes of acute pancreatitis who presented with large bowel obstruction secondary to pancreatic colonic fistula. Resolution of large bowel obstruction and pancreatic colonic fistula was achieved with pancreatic duct stenting. Conclusion. Pancreatic colonic fistula can present as large bowel obstruction. Patients with resolved acute pancreatitis who have radiographic evidence of splenic flexure obstruction, but without evidence of mechanical obstruction on colonoscopy, should be considered for ERCP to evaluate for PCF. PCF not associated with walled off pancreatic necrosis or peritoneal abscess can be treated conservatively with pancreatic duct stenting.

    Megacystis microcolon intestinal hypoperistalsis syndrome (MMIHS) is a congenital visceral myopathy characterized by severe dilation of the urinary bladder and defective intestinal motility. The genetic basis of MMIHS has been ascribed to spontaneous and autosomal dominant mutations in actin gamma 2 (ACTG2), a smooth muscle contractile gene. However, evidence suggesting a recessive origin of the disease also exists. Using combined homozygosity mapping and whole exome sequencing, a genetically isolated family was found to carry a premature termination codon in Leiomodin1 (LMOD1), a gene preferentially expressed in vascular and visceral smooth muscle cells. Parents heterozygous for the mutation exhibited no abnormalities, but a child homozygous for the premature termination codon displayed symptoms consistent with MMIHS. We used CRISPR-Cas9 (CRISPR-associated protein) genome editing of Lmod1 to generate a similar premature termination codon. Mice homozygous for the mutation showed loss of LMOD1 protein and pathology consistent with MMIHS, including late gestation expansion of the bladder, hydronephrosis, and rapid demise after parturition. Loss of LMOD1 resulted in a reduction of filamentous actin, elongated cytoskeletal dense bodies, and impaired intestinal smooth muscle contractility. These results define LMOD1 as a disease gene for MMIHS and suggest its role in establishing normal smooth muscle cytoskeletal–contractile coupling. PMID:28292896

    2016-08-23

    Oedema can occur in handled tissues following upper gastrointestinal surgery with anastomosis formation. Obstruction of the lumen may result in delayed return of enteric function. Intravenous steroid use may be beneficial. Three cases of delayed emptying following fundoplication, gastro-enteric and entero-enteric anastomoses are reviewed. Conservative management with supportive measures failed. Dexamethasone was administered to treat the oedematous obstruction. A literature review in PubMed, Cochrane database and Medline for English language publications on the use of dexamethasone in the treatment of acute post surgical oedema of the upper gastrointestinal was conducted. Administration of dexamethasone led to resolution of symptoms and successful outcome. No reports on the use of steroids in this context were identified in the literature. The use of dexamethasone may effectively treat intestinal obstruction due to inflammatory or oedematous cause in the early post-operative period.

    Purpose To determine whether adding unenhanced computed tomography (CT) to contrast material-enhanced CT improves the diagnostic performance of decreased bowel wall enhancement as a sign of ischemia complicating mechanical small bowel obstruction (SBO). Materials and Methods This retrospective study was approved by the institutional review board, which waived the requirement for informed consent. Two gastrointestinal radiologists independently performed retrospective assessments of 164 unenhanced and contrast-enhanced CT studies from 158 consecutive patients (mean age, 71.2 years) with mechanical SBO. The reference standard was the intraoperative and/or histologic diagnosis (in 80 cases) or results from clinical follow-up in patients who did not undergo surgery (84 cases). Decreased bowel wall enhancement was evaluated with contrast-enhanced images then and both unenhanced and contrast-enhanced images 1 month later. Diagnostic performance of decreased bowel wall enhancement and confidence in the diagnosis were compared between the two readings by using McNemar and Wilcoxon signed rank tests. Interobserver agreement was assessed by using κ statistics and compared with bootstrapping. Results Ischemia was diagnosed in 41 of 164 (25%) episodes of SBO. For both observers, adding unenhanced images improved decreased bowel wall enhancement sensitivity (observer 1: 46.3% [19 of 41] vs 65.8% [27 of 41], P = .02; observer 2: 56.1% [23 of 41] vs 63.4% [26 of 41], P = .45), Youden index (from 0.41 to 0.58 for observer 1 and from 0.42 to 0.61 for observer 2), and confidence score (P < .001 for both). Specificity significantly increased for observer 2 (84.5% [104 of 123] vs 94.3% [116 of 123], P = .002), and interobserver agreement significantly increased, from moderate (κ = 0.48) to excellent (κ = 0.89; P < .0001). Conclusion Adding unenhanced CT to contrast-enhanced CT improved the sensitivity, diagnostic confidence, and interobserver agreement of the diagnosis of ischemia

    Strangulated small bowel obstruction is a complication after abdominal surgery, which is rare in renal transplant patients. A 61-year-old man with a strangulated small bowel obstruction underwent renal transplant surgery 7 years before the current admission. He was admitted to our hospital for abdominal pain, nausea, and abdominal distention. An abdominal computed tomography and an ultrasound examination showed intestinal expansion and fluid collection without ascites. His disease was diagnosed as a small bowel obstruction and conservative treatment was begun. However, because of increasing abdominal pain and the collection of ascites, he underwent an emergency laparotomy and was diagnosed as having a strangulated small bowel obstruction. A fibrous cord had formed between the peritoneum (beside the transplanted kidney) and the root of the sigmoid mesocolon, strangulating the looped ileum and causing bleeding necrosis and hemorrhagic ascites collection. The cord and the necrotic ileum were resected, followed by an end-to-end anastomosis. He was discharged 17 days after the surgery in good condition. This is the first reported case of a person having a strangulated small bowel obstruction by a fibrous cord, who did not have a history of laparotomy after renal transplant. A strangulated small bowel obstruction after a renal transplant in a patient with no history of a laparotomy is a rare, but possible postoperative complications should be considered when making a differential diagnosis.

    The intestinal epithelium constitutes a first line of defense of the innate immune system. Epithelial dysfunction is a hallmark of intestinal disorders such as inflammatory bowel diseases (IBDs). The actin cytoskeleton controls epithelial barrier integrity but the function of actin regulators such as cortactin is poorly understood. Given that cortactin controls endothelial permeability, we hypothesized that cortactin is also important for epithelial barrier regulation. We found increased permeability in the colon of cortactin-KO mice that was accompanied by reduced levels of ZO-1, claudin-1, and E-cadherin. By contrast, claudin-2 was upregulated. Cortactin deficiency increased RhoA/ROCK1-dependent actomyosin contractility, and inhibition of ROCK1 rescued the barrier defect. Interestingly, cortactin deficiency caused increased epithelial proliferation without affecting apoptosis. KO mice did not develop spontaneous colitis, but were more susceptible to dextran sulfate sodium colitis and showed severe colon tissue damage and edema formation. KO mice with colitis displayed strong mucus deposition and goblet cell depletion. In healthy human colon tissues, cortactin co-localized with ZO-1 at epithelial cell contacts. In IBDs patients, we observed decreased cortactin levels and loss of co-localization with ZO-1. Thus, cortactin is a master regulator of intestinal epithelial barrier integrity in vivo and could serve as a suitable target for pharmacological intervention in IBDs.Mucosal Immunology advance online publication, 25 January 2017; doi:10.1038/mi.2016.136.

    The clinical symptoms of pylephlebitis caused by acute appendicitis are varied and atypical, which leads to delayed diagnosis and poor outcomes. Here, we report a case of intestinal necrosis caused by thrombophlebitis of the portomesenteric veins as a complication of acute appendicitis after appendectomy. The patient had acute abdominal pain with tenderness and melena on the 3rd day after appendectomy for the treatment of gangrenous appendicitis. He was diagnosed with intestinal infarction caused by thrombophlebitis of the portomesenteric veins based on enhanced CT and diagnostic abdominal paracentesis. The patient was treated by bowel excision anastomosis and thrombectomy. After postoperative antibiotic and anticoagulation treatments, the patient recovered well and was discharged 22 days after the 2nd operation. A follow-up CT scan showed no recurrence of portomesenteric veins thrombosis 3 months later. Thrombophlebitis of the portomesenteric veins is a rare but fatal complication of acute appendicitis. For all the cases with acute abdominal pain, the possibility of thrombophlebitis should be considered as a differential diagnosis. Once pylephlebitis is suspected, enhanced CT scan is helpful for early diagnosis, and sufficient control of inflammation as well as anticoagulant therapy should be performed.

    There is substantial evidence that gut barrier failure is associated with distant organ injury and systemic inflammation. After major trauma or stress, the factors and mechanisms involved in gut injury are unknown. Our primary hypothesis is that loss of the intestinal mucus layer will result in injury of the normal gut that is exacerbated by the presence of luminal pancreatic proteases. Our secondary hypothesis is that the injury produced in the gut will result in the production of biologically active mesenteric lymph and consequently distant organ (i.e., lung) injury. To test this hypothesis, five groups of rats were studied: 1) uninstrumented naive rats; 2) control rats in which a ligated segment of distal ileum was filled with saline; 3) rats with pancreatic proteases placed in their distal ileal segments; 4) rats with the mucolytic N-acetylcysteine (NAC) placed in their distal ileal segments; and 5) rats exposed to NAC and pancreatic proteases in their ileal segments. The potential systemic consequences of gut injury induced by NAC and proteases were assessed by measuring the biological activity of mesenteric lymph as well as gut-induced lung injury. Exposure of the normal intestine to NAC, but not saline or proteases, led to increased gut permeability, loss of mucus hydrophobicity, a decrease in the mucus layer, as well as morphological evidence of villous injury. Although proteases themselves did not cause gut injury, the combination of pancreatic proteases with NAC caused more severe injury than NAC alone, suggesting that once the mucus barrier is impaired, luminal proteases can injure the now vulnerable gut. Because comparable levels of gut injury caused by systemic insults are associated with gut-induced lung injury, which is mediated by biologically active factors in mesenteric lymph, we next tested whether this local model of gut injury would produce active mesenteric lymph or lead to lung injury. It did not, suggesting that gut injury by itself may not

    Situs ambiguus is a rare lateralization anomaly that is frequently associated with other malformations, including preduodenal portal vein (PDPV), intestinal malrotation, and cardiovascular anomalies. This is a case report on a newborn that was clinically diagnosed with situs ambiguus and midgut volvulus. During surgery the patient was found to have intestinal malrotation, Meckel's diverticulum, and PDPV that was not a direct cause of duodenal obstruction. The patient was treated with Ladd's procedure and resection of Meckel's diverticulum. It is important to be familiar with the spectrum of situs anomalies to prevent trauma to the portal vein with serious complications during surgery.

    Haemosuccus Pancreaticus is defined as upper gastro intestinal (GI) bleeding from the ampula of vater via the pancreatic duct. It is most commonly associated with pancreatic inflammation, erosion of the pancrease by aneurysm or pseudo-aneurysm of the splenic artery. We report a 69 year old man with previous history of acute pancreatitis who was admitted with recurrent haematemesis. Initial upper GI endocopy was normal, while admitted, he collapse with abdominal pain and hypotension. He was resuscitated with blood and intravenous fluid. Repeat upper GI endocopy showed fresh blood in the duodenum, but no active bleeding site was demonstrated. An urgent coeliac axis CT angiogram was done which showed an splenic artery pseudo-aneurysm, which was successfully embolized. Patient is well 9 months after the procedure. This case highlights the importance of considering coeliac axis CT angiogram as part of investigation for obscure GI bleeding.

    Mesenteric venous thrombosis is a rare cause of intestinal ischemia which is potentially life-threatening because it can lead to intestinal infarction. Mesenteric venous thrombosis rarely develops after abdominal surgery and is usually associated with coagulation disorders. Associated symptoms are generally subtle or nonspecific, often resulting in delayed diagnosis. A 68-year-old woman underwent laparoscopic exploration for small bowel obstruction, secondary to adhesions. During the procedure, an intestinal perforation was identified and repaired. Postoperatively, the abdominal pain persisted and repeat exploration was undertaken. At repeat exploration, a perforation was identified in the small bowel with a surrounding abscess. After the second operation, the abdominal pain improved but anorexia persisted. Contrast enhanced abdominal computed tomography was performed which revealed superior mesenteric venous thrombosis. Anticoagulation therapy with heparin was started immediately and the thrombus resolved over the next 6 days. Although rare, this complication must be considered in patients after abdominal surgery with unexplained abdominal symptoms. PMID:24455391

  5. Intrarenal Doppler Indices in Acute Ureteric Obstruction

    PubMed Central

    2014-01-01

    Context: Urolithiasis remains a major health problem despite advances in therapy. Obstruction results in an increase in pressure within the urinary tract, causing structural and physiologic changes. This study aimed to calculate the intra renal Resistivity Index (RI) of acutely obstructed kidney, to determine the significance of Resistivity Index Ratio (RIR) and difference in Resistivity Index of obstructed and contralateral non obstructed kidney. Materials and Methods: Prospective study with renal Doppler for patients presenting with acute unilateral ureteric obstruction. Seventy two patients between the age group 20-45 y presenting to the Department of Radiodiagnosis, between January – December 2006 with acute unilateral ureteric obstruction were included in the study. Gray scale and Doppler evaluation of the kidneys done; with assessment of the ureteric calculus. Renal Doppler indices calculated and follow up of the same done after relief of obstruction. Statistical Analysis: Statistical analysis was done using SPSS Software V13 and p-value <0.05 was considered as statistically significant. Results: Forty two patients (58.33%) had mild, 28 (38.89%) moderate and 2 (2.78%) severe hydronephrosis. The mean RI of the obstructed kidney was 0.66±0.88 and that of contralateral non obstructed kidney was 0.569±0.05. Delta RI between the obstructed and contralateral non obstructed kidney was 0.08±0.03. The mean RIR between the obstructed and non obstructed kidney was 1.12±0.04 and the same after relief of obstruction was 1.03±0.06. Conclusion: The intrarenal Resistivity indices are less sensitive indicators in predicting the diagnosis of acute ureteric obstruction, although Resistivity Index Ratio appears to be a better parameter. The indices within the normal range do not rule out the absence of obstruction. Hence these parameters should not be interpreted in isolation. PMID:25654006

    The authors report the case of a 12-year-old boy admitted to the surgical emergency department of Charles de Gaulle Paediatric Teaching Hospital of Ouagadougou for acute abdominal pain. A strangulation of the terminal ileum by a tumour-like appendix wound around the bowel loop was seen during operation. The histological examination of the removed appendix disclosed eggs of Schistosoma haematobium and concluded to bilharzian appendicitis. A course of praziquantel treatment was instituted, and the patient underwent an event-free recovery. Such cases report are infrequent, even in areas where bilharzia-related diseases are endemic. It is important to recognise them and to treat them in an aetiological manner so as to prevent any potential complications. The diagnosis is always an operatory and histological curiosity. Appendectomy and treatment with a course of praziquantel seem quite suitable for this situation.

    E-cadherin expression disruption is commonly observed in metastatic epithelial cancers and is a crucial step in gastric cancer (GC) initiation and progression. As aberrant expression of microRNAs often perturb the normal expression/function of pivotal cancer-related genes, we characterized and dissected a pathway that causes E-cadherin dysfunction via loss of microRNA-101 and up-regulation of EZH2 expression in GC. MicroRNA microarray expression profiling and array-CGH were used to reinforce miR-101 involvement in GC. By using quantitative real-time PCR and quantitative SNaPshot genomic PCR, we confirmed that miR-101 was significantly down-regulated in GC (p < 0.0089) in comparison with normal gastric mucosas and, at least in 65% of the GC cases analysed, this down-regulation was caused by deletions and/or microdeletions at miR-101 genomic loci. Moreover, around 40% of cases showing miR-101 down-regulation displayed concomitant EZH2 over-expression (at the RNA and protein levels), which, in turn, was associated with loss/aberrant expression of E-cadherin. Interestingly, this occurred preferentially in intestinal-type GCs, retaining allele(s) untargeted by classical CDH1-inactivating mechanisms. We also demonstrated that miR-101 gain of function or direct inhibition of EZH2 in Kato III GC cells led to a strong depletion of endogenous EZH2 and consequent rescue of E-cadherin membranous localization, mimicking results obtained in clinical GC samples. In conclusion, we show that deletions and/or microdeletions at both miR-101 genomic loci cause mature miR-101 down-regulation, subsequent EZH2 over-expression and E-cadherin dysfunction, specifically in intestinal-type GC.

    Gallstone ileus is an uncommon type of mechanical intestinal obstruction caused by an intraluminal gallstone, and preoperative diagnosis is difficult in the Emergency department. This study is a retrospective analysis of the clinical presentation of 5 patients with gallstone ileus treated between 2000-2010. Clinical features, diagnostic testing, and surgical treatment were analyzed. Five patients were included: 2 cases showed bowel obstruction; 2 patients presented a recurrent gallstone ileus with prior surgical intervention; and one patient presented acute peritonitis due to perforation of an ileal diverticula. In all cases CT confirmed the preoperative diagnosis. In our experience, gallstone ileus may present with clinical features other than intestinal obstruction. In suspicious cases CT may be useful to decrease diagnostic delay, which is associated with more complications.

    Immune homeostasis in intestinal tissues depends on the generation of regulatory T (Treg) cells. CD103+ dendritic cells (DCs) acquire microbiota-derived material from the gut lumen for transport to draining lymph nodes and generation of receptor-related orphan γt+ (RORγt+) Helios−-induced Treg (iTreg) cells. Here we show CD40-signalling as a microbe-independent signal that can induce migration of CD103+ DCs from the lamina propria (LP) to the mesenteric lymph nodes. Transgenic mice with constitutive CD11c-specific CD40-signalling have reduced numbers of CD103+ DCs in LP and a low frequency of RORγt+Helios− iTreg cells, exacerbated inflammatory Th1/Th17 responses, high titres of microbiota-specific immunoglobulins, dysbiosis and fatal colitis, but no pathology is detected in other tissues. Our data demonstrate a CD40-dependent mechanism capable of abrogating iTreg cell induction by DCs, and suggest that the CD40L/CD40-signalling axis might be able to intervene in the generation of new iTreg cells in order to counter-regulate immune suppression to enhance immunity.

    Bezoars are aggregates of indigested foreign material that accumulate in the gastroenteric tract, expecially in the stomach and in the narrowest points of the small bowel. They often occur in subjects who follow a diet rich in fruit and vegetables and in those one who previously underwent gastric resective surgery for peptic ulcer. Bezoar formation has even been observed in case of reduced gastric motility and secretion due to diabetes, hypothyroidism, pernicious anemia, myotonic syndromes, and Guillain-Barré syndrome. As they are an uncommon cause of small bowel obstruction, phytobezoars are often not considered in the differential diagnosis of occlusive intestinal syndromes and so frequently come as an intraoperative finding. A consequence of this missed diagnosis in the preoperative period is an unnecessary diagnostic delay that can significantly increase morbidity and mortality. This case report illustrates the need to include phytobezoars in the preoperative diagnostic workout of intestinal obstruction in order to rule out the presence of multiple bezoars and prevent recurrent obstruction. Now that phytobezoars are becoming a less infrequent cause of small bowel obstruction than previously thought, such a diagnostic possibility should always be considered.

    Obstruction of bile flow results in bacterial proliferation and mucosal injury in the small intestine that can lead to the translocation of bacteria across the epithelial barrier and systemic infection. These adverse effects of biliary obstruction can be inhibited by administration of bile acids. Here we show that the farnesoid X receptor (FXR), a nuclear receptor for bile acids, induces genes involved in enteroprotection and inhibits bacterial overgrowth and mucosal injury in ileum caused by bile duct ligation. Mice lacking FXR have increased ileal levels of bacteria and a compromised epithelial barrier. These findings reveal a central role for FXR in protecting the distal small intestine from bacterial invasion and suggest that FXR agonists may prevent epithelial deterioration and bacterial translocation in patients with impaired bile flow.

    This case presents an uncommon but important mechanism of muscular left ventricular outflow obstruction in hypertrophic cardiomyopathy due to anomalous and direct papillary muscle insertion into the anterior mitral leaflet, a finding reliably identified clinically by cardiac magnetic resonance imaging. The identification of this left ventricular outflow tract morphology is important before invasive ventricular septal reduction therapy because it dictates a specific surgical strategy. These findings further support the role of cardiac magnetic resonance imaging in the early evaluation of hypertrophic cardiomyopathy patients.

    A fecaloma refers to a mass of accumulated feces that is much harder than a mass associated with fecal impaction. Fecalomas are usually found in the rectosigmoid area. A 10-year-old male with chronic constipation was admitted because of increasing abdominal pain. An abdominal computed tomography scan and a simple abdominal x-ray revealed rapidly evolving mechanical obstruction in the small intestine. Most of the fecalomas are successfully treated by conservative methods such as laxatives, enemas and rectal evacuation. When conservative treatments have failed, surgical intervention may be needed. In this case, an emergency operation was performed and a 4×3×2.5 cm fecaloma was found in the distal ileum. We thus report a case of ileal fecaloma inducing small bowel obstruction in a patient with chronic constipation, who required surgical intervention. When symptoms of acute small intestinal obstruction develop in a patient with chronic constipation, a fecaloma should be considered in differential diagnosis. PMID:26473140

    Adhesive small bowel obstruction is a frequent cause of hospital admission. Water soluble contrast studies may have diagnostic and therapeutic value and avoid challenging demanding surgical operations, but if bowel ischemia is suspected, prompt surgical intervention is mandatory. A 58-year-old patient was operated for extensive adhesive small bowel obstruction after having had two previous laparotomies for colorectal surgery, and had a complex clinical course with multiple operations and several complications. Different strategies of management have been adopted, including non-operative management with the use of hyperosmolar water soluble contrast medium, multiple surgical procedures, total parenteral nutrition (TPN) support, and finally use of antiadherences icodextrin solution. After 2 years follow-up the patient was doing well without presenting recurrent episodes of adhesive small bowel obstruction. For patients admitted several times for adhesive small bowel obstruction, the relative risk of recurring obstruction increases in relation to the number of prior episodes. Several strategies for non-operative conservative management of adhesive small bowel obstruction have already addressed diagnostic and therapeutic value of hyperosmolar water soluble contrast. According to the most recent evidence-based guidelines, open surgery is the preferred method for surgical treatment of strangulating adhesive small bowel obstruction as well as after failed conservative management. Research interest and clinical evidence are increasing in adhesions prevention. Hyaluronic acid-carboxycellulose membrane and icodextrin may reduce incidence of adhesions.

    Giardia is the best known cause of protozoal gastrointestinal disease in North America, producing significant but not life-threatening gastrointestinal distress and diarrhea. Although diagnosis of giardiasis may be challenging, treatment is usually successful. Entamoeba histolytica poses a rarer but far more difficult clinical challenge. Dysentery caused by E. histolytica may be the most feared intestinal protozoal infection, although Cryptosporidium parvum, Balantidium coli, Isospora belli, Sarcocystis species and other newly described protozoa also may cause diarrhea in healthy individuals and may result in intractable, life-threatening illness in patients with acquired immunodeficiency syndrome or other immunosuppressive diseases. Certain protozoa once considered relatively unimportant, such as Cryptosporidium, are now recognized as significant causes of morbidity even in the United States, since transmission readily occurs through contaminated water.

    Organophosphate insecticides have been directly or indirectly implicated in avian populations declining worldwide. Birds in agricultural environments are commonly exposed to these insecticides, mainly through ingestion of invertebrates after insecticide application. Despite insecticide exposure in birds occurring mostly by ingestion, the impact of organophosphates on the avian digestive system has been poorly researched. In this work we used the Japanese quail (Coturnix japonica) as an avian model to study short-term microbial community responses to a single dose of trichlorfon at low concentration in three sample origins of the gastrointestinal tract (GIT): caecum, large intestine and faeces. Using next-generation sequencing of 16S rRNA gene amplicons as bacterial markers, the study showed that ingestion of insecticide caused significant changes in the GIT microbiome. Specifically, microbiota composition and diversity differed between treated and untreated quail. Insecticide-associated responses in the caecum showed differences between sexes which did not occur with the other sample types. In caecal microbiota, only treated females showed significant shifts in a number of genera within the Lachnospiraceae and the Enterobacteriaceae families. The major responses in the large intestine were a significant reduction in the genus Lactobacillus and increases in abundance of a number of Proteobacteria genera. All microbial shifts in faeces occurred in phylotypes that were represented at low relative abundances. In general, changes in microbiota possibly resulted from contrasting responses towards the insecticide, either positive (e.g., biodegrading bacteria) or negative (e.g., insecticide-susceptible bacteria). This study demonstrates the significant impact that organophosphate insecticides have on the avian gut microbiota; showing that a single small dose of trichlorfon caused dysbiosis in the GIT of the Japanese quail. Further research is necessary to understand the

    2016-01-01

    The incidence of the diverticulum of the small bowel varies from 0.2-1.3% in autopsy studies to 2.3% when assessed on enteroclysis. It occurs mostly in patients in the 6th decade of their life. Of all the small bowel diverticuli, jejunal diverticulum is the most common type. This rare entity is usually asymptomatic. However, they may cause chronic non-specific symptoms for a long period of time like dyspepsia, chronic postprandial pain, nausea, vomiting, borborgymi, alternating diarrhoea and constipation, weight loss, anaemia, steatorrhea or rarely lead to complications like haemorrhage, obstruction, perforation. Obstruction can be due to enterolith, adhesions, intussusception, and volvulus. The condition is difficult to diagnose because patients are generally presented with symptoms that mimic other diseases. It is important for clinicians to have awareness of this entity. Here, we present a case of multiple jejunal diverticuli with a history of repeated attacks of diverticulitis over past 20 years, which were misdiagnosed and now presented with intestinal obstruction due to volvulus of the involved segment along with mesentery around its axis. Resection of the diverticuli segment of jejunum was done with end-to-end jejuno-jejunal anastomosis. The patient is asymptomatic since 10 months of follow-up. PMID:27853337

    Oxalate nephropathy is an uncommon cause of acute kidney injury. Far rarer is its association with scleroderma, with only one other published case report in the literature. We report a case of a 75-year-old African-American female with a history of systemic scleroderma manifested by chronic pseudo-obstruction and small intestinal bacterial overgrowth (SIBO) treated with rifaximin, who presented with acute kidney injury with normal blood pressure. A renal biopsy demonstrated extensive acute tubular injury with numerous intratubular birefringent crystals, consistent with oxalate nephropathy. We hypothesize that her recent treatment with rifaximin for SIBO and decreased intestinal transit time in pseudo-obstruction may have significantly increased intestinal oxalate absorption, leading to acute kidney injury. Oxalate nephropathy should be considered in the differential diagnosis of acute kidney injury in scleroderma with normotension, and subsequent evaluation should be focused on bowel function to include alterations in gut flora due to antibiotic administration.

    2013-01-01

    Obstructive sleep apnoea is an increasingly common disorder of repeated upper airway collapse during sleep, which leads to oxygen desaturation and disrupted sleep. Symptoms include snoring, witnessed apnoeas, and sleepiness. Pathogenesis varies; predisposing factors include small upper airway lumen, unstable respiratory control, low arousal threshold, small lung volume, and dysfunctional upper airway dilator muscles. Risk factors include obesity, male sex, age, menopause, fluid retention, adenotonsillar hypertrophy, and smoking. Obstructive sleep apnoea causes sleepiness, road traffic accidents, and probably systemic hypertension. It has also been linked to myocardial infarction, congestive heart failure, stroke, and diabetes mellitus though not definitively. Continuous positive airway pressure is the treatment of choice, with adherence of 60–70%. Bi-level positive airway pressure or adaptive servo-ventilation can be used for patients who are intolerant to continuous positive airway pressure. Other treatments include dental devices, surgery, and weight loss. PMID:23910433

    The mass mortality of pond-reared scattered mirror carp, Cyprinus carpio, caused by Thelohanellus kitauei, occurred at fish farms in Sichuan Province, southwest China. Morphological and molecular analyses were supplemented with histological evaluation of infected tissues to better understand the route of infection and the pathological effects of T. kitauei on the fish host. The intestine of the diseased host was full of large cysts of the myxosporean. The cysts range from 2 cm to 3.6 cm in diameter. Histopathology indicated that T. kitaue i first invaded the submucosa of the host intestine and then moved into the mucosa layers with the development of their spores, finally entering into the enteric cavity of the hosts after the disruption of mucosa layers. The pyriform spores of T. kitauei were surrounded by the transparent spore sheath, measuring 25.98 μm±0.95 μm in body length, 8.72 μm±0.51 μm in body width, and 7.86 μm±0.26 μm in body thickness. The single polar capsule was pyriform, measuring 14.73 μm±0.92 μm in length and 6.82 μm±0.45 μm in width, with eight to 10 turns of filament coils winding inside. Phylogenetic analysis based on the 18S small-subunit ribosomal DNA sequences indicated that minimal genetic differences were present between T. kitauei samples from South Korea and from China. Close affinity was found between the genus Thelohanellus and Myxobolus. Additionally, two polar capsule nuclei were found at the anterior end of the single polar capsule in spores of T. kitauei stained with hematoxylin and eosin, which suggested the separation of the genus Thelohanellus from Myxobolus.

    Anadromous alewives, Alosa pseudoharengus, have experienced significant population level declines caused by factors including habitat destruction. Alewives occur in two different life histories, anadromous and landlocked forms. The landlocked alewife evolved from ancestral anadromous populations, resulting in an exclusively freshwater and phenotypically unique form. The occurrence of parasites in a host is linked to the environment, making alewives an ideal model to compare parasitology within a single species with contrasting life histories. Currently, little information exists on the presence and impacts of parasites in these fish populations; the present study sets out to better understand coccidiosis in the threatened anadromous populations and to understand how coccidian parasites compare in both life history forms. The intestinal coccidian, Goussia ameliae n. sp., was described infecting the pyloric cecum of 76% and 86% of young-of-the-year and adult anadromous alewives, respectively, from the Maurice River, New Jersey, USA. The coccidian was found in landlocked alewife populations with a prevalence of 92% and 34% in YOY and adult fish, respectively. An analysis of the small subunit 18S ribosomal RNA gene of G. ameliae from both life history forms demonstrated that the coccidian had 100% sequence identity, confirming the same parasite species in both forms. Though genetic analysis demonstrated G. ameliae to be identical, some differences were observed in sporulation and morphology of the parasite within the two populations. The sporocysts in anadromous populations were shorter and wider, and sporulation timing differed from that of landlocked fish. These differences may either be attributed to differences in the host type or to the sporulation environment. Lastly, alewives from landlocked populations were frequently co-infected with a second coccidian species in the posterior intestine, which occurred at a lower prevalence. This species, G. alosii n. sp., was

    Objective: We investigated the effect of xuesaitong on intestinal barrier dysfunction and related mechanisms in a rat model for intestinal ischemia-reperfusion. Methods: Rats were divided into sham-operated, disease-model and Xuesaitong-treated groups. In the disease-model and Xuesaitong-treated rats an intestinal ischemia-reperfusion injury (IRI) model was introduced, which was created by a temporary obstruction of the superior mesenteric artery (SMA). The xuesaitong group was pre-treated with injections into the abdominal cavity prior to the generation of the IRI model. Tissue changes were evaluated using H&E staining and electron microscopy. Samples were analyzed at 0, 3 and 24 h post IRI. Ascites volumes as well as small intestinal mucosa bleeding, injury scores, wet to dry weight ratios, and propulsions were evaluated. Apoptotic rates were determined with TUNNEL assays. Blood serum tumor necrosis factor-α (TNF-α) levels were measured using ELISA, and Bcl-2 and caspase-3 expression in small intestinal mucosa measured using immunohistochemistry. Results: We determined a significant increase of pathological damage to small intestinal tissues, intestinal wet to dry ratios, ascites volume, TNF-α levels, apoptosis rates of small intestinal mucosa, and expression of Bcl-2 and caspase-3 proteins in the disease-model group compared to the sham-operated group (P < 0.001), and intestinal motility was significantly decreased (P < 0.001). However, comparisons between disease-model and xuesaitong pre-treated animals revealed, that in the treatment group these changes occurred in significant less severities. Conclusions: Xuesaitong can effectively alleviate intestinal barrier dysfunction caused by ischemia-reperfusion injury by reducing TNF-α, up-regulating Bcl-2 and down-regulating caspase-3 expression, in addition to increasing peristalsis.

    Bronchitis and emphysema have long been described as diseases of miners, but the precise contribution of occupational exposures to coal and other mine dusts in causing these disorders, as opposed to cofactors such as social class, environmental pollution, and cigarette smoking, has not been fully defined. Epidemiologic studies have attempted, with varying degrees of success, to determine the incidence and severity of chronic obstructive pulmonary diseases in miners as compared to the general population. The results from these studies, and those in other nonmining industries with dust exposures, are examined. 98 refs.

    Large-bowel obstruction is an abdominal emergency with high morbidity and mortality rates if left untreated. Although abdominal radiography is usually the initial imaging study performed in patients suspected of having large-bowel obstruction, it may not be sufficient to distinguish obstruction from other causes of colonic dilatation. Computed tomography is the imaging method of choice as it can establish the diagnosis and cause of large-bowel obstruction. A contrast agent enema may be used to confirm or exclude large-bowel obstruction. In this review, the imaging findings in multiple causes of large-bowel obstruction are illustrated and compared with acute colonic pseudo-obstruction.

    Severe fever with thrombocytopenia syndrome (SFTS) is an emerging disease that causes fever, enteritis, thrombocytopenia, and leucopenia and can be fatal in up to 30% of cases. However, the mechanism of severe disease is not fully understood. Molecular imaging approaches, such as positron-emission tomography (PET), are functional in vivo imaging techniques that provide real-time dynamics of disease progression, assessments of pharmacokinetics, and diagnoses for disease progression. Molecular imaging also potentially provides useful approaches to explore the pathogenesis of viral infections. Thus, the purpose of this study was to image the pathological features of SFTSV infection in vivo by PET imaging. In a mouse model, we showed that 18F-FDG accumulations clearly identified the intestinal tract site as a pathological site. We also demonstrated that 18F-FDG PET imaging can assess disease progression and response to antiserum therapy within the same individual. This is the first report demonstrating a molecular imaging strategy for SFTSV infection. Our results provide potentially useful information for preclinical studies such as the elucidation of the mechanism of SFTSV infection in vivo and the assessment of drugs for SFTS treatment.

    The nasogastric tube (NGT) has become a frequently used device to alleviate gastrointestinal symptoms. Nasogastric tube syndrome (NTS) is an uncommon but potentially life-threatening complication of an indwelling NGT. NTS is characterized by acute upper airway obstruction due to bilateral vocal cord paralysis. We report a case of a 76-year-old man with NTS, induced by an indwelling long intestinal tube. He was admitted to our hospital for treatment of sigmoid colon cancer. He underwent sigmoidectomy to release a bowel obstruction, and had a long intestinal tube inserted to decompress the intestinal tract. He presented acute dyspnea following prolonged intestinal intubation, and bronchoscopy showed bilateral vocal cord paralysis. The NGT was removed immediately, and tracheotomy was performed. The patient was finally discharged in a fully recovered state. NTS be considered in patients complaining of acute upper airway obstruction, not only with a NGT inserted but also with a long intestinal tube.

    Intestinal capillariasis caused by Capillaria philippinensis appeared first in the Philippines and subsequently in Thailand, Japan, Iran, Egypt, and Taiwan, but most infections occur in the Philippines and Thailand. As established experimentally, the life cycle involves freshwater fish as intermediate hosts and fish-eating birds as definitive hosts. Embryonated eggs from feces fed to fish hatch and grow as larvae in the fish intestines. Infective larvae fed to monkeys, Mongolian gerbils, and fish-eating birds develop into adults. Larvae become adults in 10 to 11 days, and the first-generation females produce larvae. These larvae develop into males and egg-producing female worms. Eggs pass with the feces, reach water, embryonate, and infect fish. Autoinfection is part of the life cycle and leads to hyperinfection. Humans acquire the infection by eating small freshwater fish raw. The parasite multiplies, and symptoms of diarrhea, borborygmus, abdominal pain, and edema develop. Chronic infections lead to malabsorption and hence to protein and electrolyte loss, and death results from irreversible effects of the infection. Treatment consists of electrolyte replacement and administration of an antidiarrheal agent and mebendazole or albendazole. Capillariasis philippinensis is considered a zoonotic disease of migratory fish-eating birds. The eggs are disseminated along flyways and infect the fish, and when fish are eaten raw, the disease develops. Images PMID:1576584

    Ogilvie's syndrome, or acute colonic pseudo-obstruction, is characterized by massive dilation of the colon without mechanical obstruction. Water and electrolytes often can be sequestered in the dilated intestinal loops resulting in profuse and watery diarrhea as well as hypokalemia. We report an anuric, end-stage renal disease (ESRD) patient undergoing peritoneal dialysis (PD) who developed acute colonic pseudo-obstruction causing a prolonged hospitalization. He also developed severe hypokalemia with a serum potassium (K+) as low as 2.4 mEq/L and required 180 - 240 mEq of potassium chloride per day for more than a month to correct it. While PD K+ losses often contribute to hypokalemia, the PD K+ loss was estimated to be only 39 mEq/day. Therefore, PD could only contribute modestly to the recalcitrant hypokalemia observed during the episode of pseudo-obstruction. It has been shown, however, that patients with colonic pseudo-obstruction have enhanced colonic K+ secretion. In addition, experimental studies in patients with chronic kidney disease (CKD) have demonstrated that colonic K+ excretion can be up to 3 times greater than in individuals with normal renal function. This increase may involve an upregulation of the large conductance K+ channel (maxi-K), also known as the BK channel, in the apical border of the colonocytes. We suggest that ESRD may have placed our patient at a greater risk of developing hypokalemia as his colon may have already adapted to secrete more K+. Clinicians should be aware of this extrarenal K+ wasting etiology in patients with colonic pseudo-obstruction, particularly in those with CKD where such a severe K+ deficit is not anticipated and, therefore, may inhibit more rigorous K+ replacement.

    Obstructive sleep apnea (OSA) is a sleep respiratory disorder characterized by recurrent episodes of complete or partial airway obstruction, resulting in apneas or hypopneas. OSA could contribute to atherosclerosis through direct and indirect mechanisms. Endothelial dysfunction, sympathetic stimulation, and proinflammatory cytokine modulation caused by OSA play significant role to an atherosclesrotic event. Other risk factors of atherosclerosis like hypertension and diabetes mellitus also associated with OSA. Animal and clinical studies recently showed promising data to prove association between OSA, atherosclerosis, and its risk factors. However, provided data has not showed consistent result. In the future, demand of further research both basic and clinical sciences need to be fulfilled.

    Thermally-induced gels were made from white croaker (Pennahia argentata) meat in the presence of its organ extracts by pre-heating at 40 and 65°C for 20 min and subsequent heating at 85°C for 20 min. The breaking strength of the gels decreased with increasing concentrations of the intestinal extracts accompanying decomposition of myosin heavy chains. However, no significant changes in the gel strength occurred when the kidney extract was added. The proteolytic activity in the intestinal extracts examined in the meat homogenate had a maximum at 60°C and pH 8.90. These results suggest that the intestinal rather than kidney proteolytic activities are responsible for gel softening known as a modori phenomenon. Thus, the removal of intestinal tracts is essential to maintain a high quality of surimi-based products.

    2002-01-01

    The obstructive sleep apnea syndrome (OSAS) is caused by an intermittent and repetitive obstruction of the upper respiratory tract during sleep, which leads to a complete (apnea) or partial (hypopnea) block of air flow. It is quite prevalent, being seen in 4-6% of males and 2% of females. Structural abnormalities present in the upper respiratory tract and obesity are the fundamental etiological factors. Clinical manifestations are due to sleep fragmentation and oxygen desaturation which cause the apnea. Day hypersomnia, snoring and episodes of apnea described by the spouse are the three basic symptoms. The diagnosis is based on polysomnography, which can be substituted for a night cardiorespiratory polygraphy. It has an important morbimortality rate, mainly due to traffic and labor accidents, ischemic heart disease and chronic respiratory failure. The treatment is multifactorial. First, eliminating alcohol and hypnotic drugs. Obesity, which is almost always present, must also be corrected. Structural abnormalities of the upper respiratory tract may require a surgical solution. The treatment preferred nowadays is the application of a nasal continuous positive airway pressure (CPAP) while the patient is asleep. It should be considered for those symptomatic patients with an apnea-hypopnea index over 30, or if the index is below 30, than when a respiratory insufficiency or cardiovascular risk factors are present. In some cases surgical procedures may be considered, such as uvulopalatopharyngoplasty.

    Trans - omental hernia is very rare, accounting to 1-4% of all internal hernias which is an unusual cause of small bowel obstruction. Here we present a case report of a small bowel obstruction in a female due to trans - omental hernia presenting with central abdominal pain, distension and bilious vomiting. She had no previous history of trauma, surgery. Plain X-ray abdomen erect showed multiple air fluid levels with dilated small bowel loops. Emergency laparotomy revealed a segment of congested small bowel loop (ileum) through a defect in greater omentum. On table the herniated bowel loop was reduced and the defect in greater omentum was closed primarily. There was no necessity for bowel resection as it regained normal colour after reduction. Postoperative period was uneventful with complete resolution of symptoms. This case is presented for its rarity and its importance in clinical differential diagnosis of acute abdomen due to small bowel obstruction.

    Gallstone ileus (GI) is a mechanical obstruction of small or large bowel caused by gallstone passed to the intestinal lumen through spontaneous or postoperative biliodigestive fistula. A 42-year-old female patient was admitted with the clinical presentation of small bowel obstruction. She underwent hepaticojejunostomy 4 years prior to admission for primary sclerosing cholangitis. Barium meal follows through revealed Rigler's triad. The patient underwent laparotomy which revealed GI. A “stone on a suture” was removed through enterotomy. Patients after cholecystectomy and hepaticojejunostomy can develop GI. Nonabsorbable suture used to create biliodigestive anastomosis can appear to become the frame of a “stone on a suture.” PMID:27904625

    Study Objectives: The choice of mask interface used with continuous positive airway pressure (CPAP) therapy can affect the control of upper airway obstruction (UAO) in obstructive sleep apnea (OSA). We describe a case series of four patients with paradoxical worsening of UAO with an oronasal mask and the effect of changing to a nasal mask. Methods: We retrospectively reviewed the case histories of 4 patients and recorded patient demographics, in-laboratory and ambulatory CPAP titration data, CPAP therapy data, type of mask interface used and potential confounding factors. Results: The 4 cases (mean ± SD: age = 59 ± 16 y; BMI = 30.5 ± 4.5 kg/m2) had a high residual apnoea-hypopnea index (AHI) (43 ± 14.2 events/h) and high CPAP pressure requirements (14.9 ± 6.6 cmH2O) with an oronasal mask. Changing to a nasal mask allowed adequate control of UAO with a significant reduction in the average residual AHI (3.1 ± 1.5 events/h). In two of the four cases, it was demonstrated that control of UAO was obtained at a much lower CPAP pressure compared to the oronasal mask (Case one = 17.5 cmH2O vs 12cmH2O; Case two = 17.9 cmH2O vs 7.8 cmH2O). Other potential confounding factors were unchanged. There are various physiological observations that may explain these findings but it is uncertain which individuals are susceptible to these mechanisms. Conclusions: If patients have OSA incompletely controlled by CPAP with evidence of residual UAO and/or are requiring surprisingly high CPAP pressure to control OSA with an oronasal mask, the choice of mask should be reviewed and consideration be given to a trial of a nasal mask.

    Duplex-Doppler sonography could be employed in the quantitative investigation of intestinal motility. Preliminary data indicate reproductivity of the method in normal subjects and possible clinical applications in some pathological conditions affecting intestinal transit. Particularly, the possibility to discriminate between segments at different peristaltic activity seems to be very useful in intestinal obstruction. Further studies are necessary to validate this method.

    Introduction Intra-aortic balloon pumping is used in elective percutaneous coronary intervention for increasing coronary blood flow. However, intra-aortic balloon pumping may decrease visceral blood flow and cause mesenteric ischemia by visceral artery obstruction. Case presentation We report the case of a 79-year-old Asian man in whom elective percutaneous coronary intervention was performed with intra-aortic balloon pumping. He died from mesenteric ischemia 25 hours after the procedure. Microscopic findings showed that intra-aortic balloon pumping had detached the aortic plaque, breaking it into systemic emboli, leading to subsequent intestinal ischemia and necrosis. Conclusions We conclude that intra-aortic balloon pumping can cause an intestinal cholesterol embolism. PMID:24951057

    Progress in double-balloon endoscopy (DBE) has allowed for the diagnosis and treatment of disease in the postoperative bowel. For example, a short DBE, which has a 2.8 mm working channel and 152 cm working length, is useful for endoscopic retrograde cholangiopancreatography in bowel disease patients. However, afferent loop and Roux-limb obstruction, though rare, is caused by postoperative recurrence of biliary tract cancer with intractable complications. Most of the clinical findings involving these complications are relatively nonspecific and include abdominal pain, nausea, vomiting, fever, and obstructive jaundice. Treatments by surgery, percutaneous transhepatic biliary drainage, percutaneous enteral stent insertion, and endoscopic therapy have been reported. The general conditions of patients with these complications are poor due to cancer progression; therefore, a less invasive treatment is better. We report on the usefulness of metallic stent insertion using an overtube for afferent loop and Roux-limb obstruction caused by postoperative recurrence of biliary tract cancer under short DBE in two patients with complexly reconstructed intestines.

    Two cases are reported of chronic, partial afferent loop obstruction with resultant obstructive jaundice in recurrent gastric cancer. The diagnosis was made by characteristic clinical presentations, abdominal computed tomography, and cholescintigraphy. Percutaneous transhepatic duodenal drainage (PTDD) provided effective palliation for both afferent loop obstruction and biliary stasis. We conclude that cholescintigraphy is of value in making the diagnosis of partial afferent loop obstruction and in differentiating the cause of obstructive jaundice in such patients, and PTDD provides palliation for those patients in whom surgical intervention is not feasible.

    Abdominal hernias are a common cause of bowel obstruction. The major types of abdominal hernias are external or abdominal wall hernias, which occur at areas of congenital or acquired weakness in the abdominal wall. An alternative entity is internal hernias, which are characterized by a protrusion of viscera through the peritoneum or mesentery. We herein present the case of a female peritoneal dialysis patient with bowel obstruction due to an internal hernia. Although an initial work-up did not lead to a correct diagnosis, an exploratory laparotomy revealed that she had intestinal herniation due to a defect in the broad ligament of the uterus, which was promptly corrected by surgery. The concerns about the perioperative dialytic management as well as the diagnostic problems regarding the disease that arose in our experience with the present patient are also discussed.

    Scope The long‐lasting consequences of nutritional programming during the early phase of life have become increasingly evident. The effects of maternal nutrition on the developing intestine are still underexplored. Methods and results In this study, we observed (1) altered microbiota composition of the colonic luminal content, and (2) differential gene expression in the intestinal wall in 2‐week‐old mouse pups born from dams exposed to a Western‐style (WS) diet during the perinatal period. A sexually dimorphic effect was found for the differentially expressed genes in the offspring of WS diet‐exposed dams but no differences between male and female pups were found for the microbiota composition. Integrative analysis of the microbiota and gene expression data revealed that the maternal WS diet independently affected gene expression and microbiota composition. However, the abundance of bacterial families not affected by the WS diet (Bacteroidaceae, Porphyromonadaceae, and Lachnospiraceae) correlated with the expression of genes playing a key role in intestinal development and functioning (e.g. Pitx2 and Ace2). Conclusion Our data reveal that maternal consumption of a WS diet during the perinatal period alters both gene expression and microbiota composition in the intestinal tract of 2‐week‐old offspring.

    Obstructive sleep apnea syndrome (OSAS) is caused by multi-level upper airway obstruction. Anatomic changes at the sites of obstruction may modify the physical or acoustic properties of snores. The surgical success of OSA depends upon precise localization of obstructed levels. We present a case of OSAS who received simultaneous dynamic MRI and snore acoustic recordings. The synchronized image and acoustic information successfully characterize the sites of temporal obstruction during sleep-disordered breathing events.

    BACKGROUND/AIM: The reliability of a quantitative method for the non-invasive assessment of intestinal disaccharide hydrolysis was assessed. METHODS: Differential excretion of intact disaccharide, expressed as ratios of lactulose to appropriate hydrolysable disaccharides in urine collected following combined ingestion, has been investigated in healthy volunteers with drug induced alpha-glucosidase inhibition, in subjects with primary hypolactasia, and patients with coeliac disease. RESULTS: Oral administration of the alpha-glucosidase inhibitor 'Acarbose' (BAY g 5421, 200 mg) together with sucrose and lactulose increased the urinary sucrose/lactulose excretion ratios (% dose/10 h) fivefold. The effect was quantitatively reproducible, a higher dose of 'Acarbose' (500 mg) increasing the excretion ratio to about 1.0 indicating complete inhibition of intestinal sucrase activity. The suitability of the method for measuring differences in dose/response and duration of action was assessed by comparing three different alpha-glucosidase inhibitors (BAY g 5421, BAY m 1099, and BAY o 1248) and found to be satisfactory. Subjects with primary adult hypolactasia had urine lactose/lactulose excretion ratios raised to values indicating reduced rather than complete absence of lactase activity whereas sucrose/lactulose ratios were not significantly affected. 'Whole' intestinal disaccharidase activity assessed by this method demonstrated impairment of lactase, sucrase, and isomaltase in eight, one, and seven, respectively, of 20 patients with coeliac disease. By contrast in vitro assay of jejunal biopsy tissue indicated pan-disaccharidase deficiency in all but five of these patients. This shows the importance of distinguishing between 'local' and 'whole' intestinal performance. CONCLUSIONS: Differential urinary excretion of ingested disaccharides provides a reliable, quantitative, and non-invasive technique for assessing profiles of intestinal disaccharidase activity.

    Intestinal anastomosis is a surgical procedure that restores bowel continuity after surgical resection to treat intestinal malignancy, inflammation, or obstruction. Despite the routine nature of intestinal anastomosis procedures, the rate of complications is high. Standard visual inspection cannot distinguish the tissue subsurface and small changes in spectral characteristics of the tissue, so existing tissue anastomosis techniques that rely on human vision to guide suturing could lead to problems such as bleeding and leakage from suturing sites. We present a proof-of-concept study using a portable multispectral imaging (MSI) platform for tissue characterization and preoperative surgical planning in intestinal anastomosis. The platform is composed of a fiber ring light-guided MSI system coupled with polarizers and image analysis software. The system is tested on ex vivo porcine intestine tissue, and we demonstrate the feasibility of identifying optimal regions for suture placement.

    A 22-year-old male sustained C-6 tetraplegia in 1992. In 1993, intravenous pyelography revealed normal kidneys. Suprapubic cystostomy was performed. He underwent open cystolithotomy in 2004 and 2008. In 2009, computed tomography revealed bilateral renal calculi. Coagulum pyelolithotomy of left kidney was performed. Pleura and peritoneum were opened. Peritoneum could not be closed. Following surgery, he developed pulmonary atelectasis; he required tracheostomy and mechanical ventilation. He did not tolerate nasogastric feeding. CT of abdomen revealed bilateral renal calculi and features of proximal small bowel obstruction. Laparotomy revealed small bowel obstruction due to dense inflammatory adhesions involving multiple small bowel loops which protruded through the defect in sigmoid mesocolon and fixed posteriorly over the area of previous intervention. All adhesions were divided. The wide defect in mesocolon was not closed. In 2010, this patient again developed vomiting and distension of abdomen. Laparotomy revealed multiple adhesions. He developed chest infection and required ventilatory support again. He developed pressure sores and depression. Later abdominal symptoms recurred. This patient's general condition deteriorated and he expired in 2011. Conclusion. Risk of postoperative complications could have been reduced if minimally invasive surgery had been performed instead of open surgery to remove stones from left kidney. Suprapubic cystostomy predisposed to repeated occurrence of stones in urinary bladder and kidneys. Spinal cord physicians should try to establish intermittent catheterisation regime in tetraplegic patients. PMID:23533931

    Identification of Lgr5 as the intestinal stem cell marker as well as the growth factors necessary to replicate adult intestinal stem cell division has led to the establishment of the methods to generate "indefinite" ex vivo primary intestinal epithelial cultures, termed "mini-intestines." Primary cultures developed from isolated intestinal crypts or stem cells (termed enteroids/colonoids) and from inducible pluripotent stem cells (termed intestinal organoids) are being applied to study human intestinal physiology and pathophysiology with great expectations for translational applications, including regenerative medicine. Here we discuss the physiologic properties of these cultures, their current use in understanding diarrhea-causing host-pathogen interactions, and potential future applications.

A method to clinically 'phenotype' AECOPD have been proposed, and 52 hospitalized chronic obstructive pulmonary disease exacerbations according to underlying aetiology have now been prospectively phenotyped. Multiple exacerbation phenotypes were identified. A subpopulation coinfected with virus and bacteria had a significantly longer length of hospital stay, and this pilot study indicates that exacerbation phenotyping may be advantageous.

    Malignant biliary obstruction is commonly caused by gall bladder carcinoma, cholangiocarcinoma and metastatic nodes. Percutaneous interventions play an important role in managing these patients. Biliary drainage, which forms the major bulk of radiological interventions, can be palliative in inoperable patients or pre-operative to improve liver function prior to surgery. Other interventions include cholecystostomy and radiofrequency ablation. We present here the indications, contraindications, technique and complications of the radiological interventions performed in patients with malignant biliary obstruction. PMID:27247718

    Objectives. To investigate the effect of the cause of acute respiratory failure and the role of comorbidities both acute and chronic on the outcome of COPD patients admitted to Respiratory Intensive Care Unit (RICU) with acute respiratory failure and treated with NIV. Design. Observational prospective study. Patients and Methods. 176 COPD patients consecutively admitted to our RICU over a period of 3 years and treated with NIV were evaluated. In all patients demographic, clinical, and functional parameters were recorded including the cause of acute respiratory failure, SAPS II score, Charlson comorbidity index, and further comorbidities not listed in the Charlson index. NIV success was defined as clinical improvement leading to discharge to regular ward, while exitus or need for endotracheal intubation was considered failure. Results. NIV outcome was successful in 134 patients while 42 underwent failure. Univariate analysis showed significantly higher SAP II score, Charlson index, prevalence of pneumonia, and lower serum albumin level in the failure group. Multivariate analysis confirmed a significant predictive value for pneumonia and albumin. Conclusions. The most important determinants of NIV outcome in COPD patients are the presence of pneumonia and the level of serum albumin as an indicator of the patient nutritional status. PMID:24563868

    Despite significant conservation intervention, the kiwi (Apteryx spp.) is in serious population decline. To increase survival in the wild, conservation management includes rearing of young birds in captivity, safe from introduced mammalian predators. However, an increase in density of immunologically naïve kiwi increases the risk of exposure to disease, including coccidia. Intestinal coccidiosis has recently been described in the kiwi, and although extra-intestinal coccidiosis was first recognized in kiwi in 1978, very little is known about this disease entity. This study used archived histological tissues and reports from routine necropsies to describe the pathology of naturally occurring extra-intestinal coccidiosis. At least 4.5% of all kiwi necropsied during 1991 to 2011 (n=558) were affected by extra-intestinal coccidiosis, and it is estimated that it caused death in 0.9 to 1.2% of kiwi in the study group. Four forms were recognized: renal, hepatic, and, less commonly, splenic and pulmonary. At necropsy, renal coccidiosis was associated with miliary white streaks and foci through the kidneys, renomegaly, and renal pallor or congestion. Renal meronts and gametocytes were confined to the distal convoluted tubules and collecting ducts, and were associated with renal tubular necrosis and tubular obstruction. Hepatic miliary pinpoint foci were present throughout the hepatic parenchyma associated microscopically with macromeronts measuring 304×227 µm. In two cases, clusters of splenic meronts were identified, and a similar lesion was identified in the pulmonary interstitium of another case. Juvenile, captive kiwi were most often affected with extra-intestinal coccidiosis, illustrating an increased expression of disease with population manipulation for conservation purposes.

    Intestines are organs that not only digest food and absorb nutrients, but also provide a defense barrier against pathogens and noxious agents ingested. Tight junctions (TJs) are the most apical component of the junctional complex, providing one form of cell-cell adhesion in enterocytes and playing a critical role in regulating paracellular barrier permeability. Alteration of TJs leads to a number of pathophysiological diseases causing malabsorption of nutrition and intestinal structure disruption, which may even contribute to systemic organ failure. Claudins are the major structural and functional components of TJs with at least 24 members in mammals. Claudins have distinct charge-selectivity, either by tightening the paracellular pathway or functioning as paracellular channels, regulating ions and small molecules passing through the paracellular pathway. In this review, we have discussed the functions of claudin family members, their distribution and localization in the intestinal tract of mammals, their alterations in intestine-related diseases and chemicals/agents that regulate the expression and localization of claudins as well as the intestinal permeability, which provide a therapeutic view for treating intestinal diseases.

    Summary Background Objective; To find out the role of MDCT in the evaluation of obstructive jaundice with respect to the cause and level of the obstruction, and its accuracy. To identify the advantages of MDCT with respect to other imaging modalities. To correlate MDCT findings with histopathology/surgical findings/Endoscopic Retrograde CholangioPancreatography (ERCP) findings as applicable. Material/Methods This was a prospective study conducted over a period of one year from August 2014 to August 2015. Data were collected from 50 patients with clinically suspected obstructive jaundice. CT findings were correlated with histopathology/surgical findings/ERCP findings as applicable. Results Among the 50 people studied, males and females were equal in number, and the majority belonged to the 41–60 year age group. The major cause for obstructive jaundice was choledocholithiasis. MDCT with reformatting techniques was very accurate in picking a mass as the cause for biliary obstruction and was able to differentiate a benign mass from a malignant one with high accuracy. There was 100% correlation between the CT diagnosis and the final diagnosis regarding the level and type of obstruction. MDCT was able to determine the cause of obstruction with an accuracy of 96%. Conclusions MDCT with good reformatting techniques has excellent accuracy in the evaluation of obstructive jaundice with regards to the level and cause of obstruction. PMID:27429673

    Intestinal obstruction as a complication of pancreatitis is infrequently recognized. Only four cases of idiopathic duodenal obstruction associated with pancreatitis have been previously reported. In a three-year study of 878 patients with pancreatitis, nine cases of idiopathic duodenal obstruction associated with pancreatitis have been found. Each of the nine cases was characterized by frank obstruction in the second or third portions of the duodenum and an intact mucosa in the area of stricture. Four patients gave an abrupt history of moderately severe pancreatitis. Resolution of the duodenal obstruction occurred by three weeks in each of these four cases. Surgical exploration in one of these patients revealed marked duodenal edema with intramural hematoma. The remaining five patients reported a chronic history of obstruction. Inadequate resolution of the obstruction after four weeks of hyperalimentation led to surgical bypass. Duodenal biopsy specimens revealed inflammation, muscle destruction, and extensive fibrosis. Duodenal involvement in the inflammatory process of moderately severe pancreatitis was discovered in 25% of the upper gastrointestinal studies, but was usually self-limiting and of a mild degree. Since contiguous duodenal edema is common and fibrosing pancreatoduodenitis only occurs in an occasional patient, surgical intervention for duodenal obstruction associated with pancreatitis should only be considered after demonstrated failure of conservative management.

    Intestinal vascular malformations, especially those in the right colon, are a frequent cause of lower gastrointestinal bleeding in adults, but they are a very rare condition in children. Symptoms include acute hemorrhage, intestinal obstruction, or chronic anemia of uncertain etiology, which is the most frequent form of presentation but the most difficult to diagnose and thus properly treat. We report the case of an 11 year old boy admitted to the Emergency Room with abdominal pain, vomits, hemodynamic decompensation, who required expansion and blood transfusion. With history ofrecurrent bloody stools since infancy with repeated normal endoscopies and Tc99 scintigraphy with chronic anemia and no improvement despite adequate treatment. In the last admission, the videocolonoscopy detected a venous vascular malformation in the ileocecal region. The angiography and the entero multislice computer tomography scanner were valuable tools to confirm the diagnosis and to select the appropriate surgical procedure for this rare condition.

    Primary enterolithiasis is a rare surgical ailment. The underlying cause is intestinal stasis. Numerous anatomical and micro environmental factors such as enteritis, incarcerated hernia, malignancy, diverticula, blind loops, and enteroenterostomy predispose to clinically significant concretions. Enterolithiasis in tuberculosis can be due to the presence of strictures, intestinal bands, or interbowel/parietal adhesions, leading to intestinal stasis. Secondary enterolithiasis is generally caused by gallstones or renal stones migrating to the gastrointestinal tract due to fistula formation. During stasis, food particles act as a nidus and calcium salts are deposited over the food particles, leading to stone formation. A 57-year-old male patient presented to the Emergency Department of Jawaharlal Nehru Medical College, AMU, Aligarh, with features of intestinal obstruction. The patient underwent emergency laparotomy, revealing 2 strictures in the distal ileum with 15.24cm of the bowel between them containing a 2×2 cm enterolith. The strictured segment was resected, and end ileostomy and mucus fistula were created. The patient’s postoperative recovery was fine, and he wasdischarged with ileostomy on antitubercular treatment (after histopathologicalconfirmation). Ileostomy closure wasplanned after 6 weeks. The incidence and prevalence of enterolithiasis has been on the rise recently because of advancement in radiological imaging studies. Endoscopic and surgical stone removal along with the treatment of the underlying pathology is recommended. PMID:27853338

    Genome-wide association studies have shown that variants in fat mass and obesity-associated (FTO) gene are robustly associated with body mass index and obesity. These FTO variants are also associated with end stage renal disease and all-cause mortality in chronic kidney diseases. However, the exact role of FTO in kidneys is currently unknown. Here we show that FTO expression is increased after ureteral obstruction and renal fibrosis. Deficiency of the FTO gene attenuates the fibrogenic responses induced by ureteral obstruction in the kidney. Renal tubular cells deficient of FTO produce less α-SMA after TGF-β stimulation. FTO is indispensable for the extracellular matrix synthesis after ureteral obstruction in kidneys. Indeed, global gene transcriptions amplitude is reduced in FTO deficient kidneys after ureteral obstruction. These data establish the importance of FTO in renal fibrosis, which may have potential therapeutic implications.

    Ultrasonography is a very useful technique for diagnosing the cause of colic in cows. It allows visualisation of abnormal reticular contour and occasionally of abnormal contractility in cows with reticuloperitonitis. In right-displaced abomasum, the dilated abomasum can be detected between the right abdominal wall and the liver. Fluid ingesta are seen ventrally and a gas cap of varying size dorsally. Dilated loops of small intestines that are almost always static are the main diagnostic criterion for ileus of the small intestine, but the cause of the ileus can only rarely be determined. Cholestasis can almost always be diagnosed by imaging a dilated biliary system. With obstruction at the level of the hepatic portal, only the intrahepatic biliary ducts are dilated, while a dilatation of the entire biliary tract, including the gallbladder, occurs in the case of an obstruction near the duodenal papilla. Urinary tract diseases cause colic in cows when concrement or inflammatory products become lodged in a ureter. The importance of ultrasonography in the diagnosis of diseases causing colic in cows varies. For example, with colic attributable to ileus of the small intestines, cholestasis or urinary tract disease, ultrasonography is a very useful diagnostic tool. On the other hand, for diagnosis of left or right displacement of the abomasum or caecal dilatation, ultrasonography is generally not required, but it is helpful in difficult cases to confirm or rule out a tentative diagnosis and to avoid an unnecessary exploratory laparotomy.

    Congenital segmental dilatation (CSD) of the intestine is a rare developmental anomaly characterized by sharply demarcated dilatation of a gastrointestinal segment and may present with intestinal obstruction. We report three cases of CSD of the intestine in neonates with varied presentation. First patient was mistaken as pneumoperitoneum on abdominal radiograph, which led to initial abdominal drain placement. The 2nd patient was a case of anorectal malformation associated with congenital pouch colon (CPC) and CSD of ileum; and the third case presented as neonatal intestinal obstruction and found to have CSD of ileum. All the patients were successfully managed in our department. PMID:27896163

    Mirror image transposition of abdominal and thoracic viscera is termed situs inversus. Duodenal obstruction in situs inversus is rare. A preduodenal portal vein, though not uncommon in situs inversus, rarely causes duodenal obstruction. Where obstruction by a preduodenal portal vein is diagnosed, a duodeno-duodenostomy is the recommended treatment. A duodenal diaphragm and other more common causes of duodenal obstruction should also be excluded in these patients.

    Bilateral ureteral obstruction in children is a rare condition arising from several medical or surgical pictures. It needs to be promptly suspected in order to attempt a quick renal function recovery. In this paper we concentrated on uncommon causes of obstruction, with the aim of giving a summary of such multiple, rare and heterogeneous conditions joint together by the common denominator of sudden bilateral ureteral obstruction, difficult to be suspected at times. Conversely, typical and well-known diseases have been just run over. We considered pediatric cases of ureteral obstruction presenting as bilateral, along with some cases which truly appeared as single-sided, because of their potential bilateral presentation. We performed a review of the literature by a search on PubMed, CrossRef Metadata Search, internet and reference lists of single articles updated to May 2014, with no time limits in the past. Given that we deal with rare conditions, we decided to include also papers in non-English languages, published with an English abstract. For the sake of clearness, we divided our research results into 8 categories: (1) urolithiasis; (2) congenital urinary tract malformations; (3) immuno-rheumatologic causes of ureteral obstruction; (4) ureteral localization of infections; (5) other systemic infective causes of ureteral obstructions; (6) neoplastic intrinsic ureteral obstructions; (7) extrinsic ureteral obstructions; and (8) iatrogenic trigonal obstruction or inflammation. Of course, different pathogenic mechanisms underlay those clinical pictures, partly well-known and partly not completely understood. PMID:25374811

    Bezoars are concretions of swallowed hair, fruit vegetable fibers, and similar substances found in the alimentary canal. The first description of a postmortem human bezoar was by Swain in 1854. Although the prevalence of bezoars in humans is low, an absence of treatment has been associated with mortality rates as high as 30%, primarily because of gastrointestinal bleeding, destruction, or perforation.

    Mutually directed connections between intestine and brain are implemented by endocrine, neural and immune systems and nonspecific natural immunity. Intestine micro flora as an active participant of intestine-brain axis not only influences intestine functions but also stimulates the development of CNS in perinatal period and interacts with higher nervous centers causing depression and cognitive disorders in pathology. A special role belongs to intestine microglia. Apart from mechanic (protective) and trophic functions for intestine neurons, glia implements neurotransmitter, immunologic, barrier and motoric functions in the intestine. An interconnection between intestine barrier function and hematoencephalic barrier regulation exists. Chronic endotoxinemia as a result of intestine barrier dysfunction forms sustained inflammation state in periventricular zone of the brain with consequent destabilization of hematoencephalic barriers and spread oF inflammation to other parts of the brain resulting in neurodegradation development.

    A patient who had undergone gastric resection for carcinoma, had closed loop obstruction of the duodenum due to neoplasia at the duodenojejunal junction. The obstruction was relieved successfully by transhepatic placement of a duodenojejunal stent. We were compelled to use the transhepatic route because a Roux-Y reconstruction had been performed. Transhepatic placement may be the only chance of palliation in a small subset of patients with malignant intestinal obstruction.

    Cardiac tumors are rare and usually indicate metastatic disease. Characterizing a tumor and reaching an exact diagnosis can be difficult. Diagnosis has been aided greatly by advances in imaging, such as cardiovascular magnetic resonance with the use of gadolinium-pentetic acid. Carcinoid tumors are neuroendocrine neoplasms that are found most often in the intestinal tract, although they can also develop in the lung, stomach, or heart. Herein, we report the case of a 72-year-old woman with a history of intestinal carcinoid disease and presenting symptoms of dizziness, fatigue, and chest pain. We used cardiovascular magnetic resonance with gadolinium enhancement to identify a large mass obstructing left ventricular outflow. The histopathologic results of an endomyocardial biopsy confirmed that the mass was a left-sided metastatic carcinoid cardiac tumor. To our knowledge, we are reporting the 1st combined use of clinical evaluation, cardiovascular magnetic resonance, and histopathologic studies to reach such a diagnosis.

    There is evidence that sensitization of neurons in dorsal root ganglia (DRG) may contribute to pain induced by intestinal injury. We hypothesized that obstruction-induced pain is related to changes in DRG neurons and satellite glial cells (SGCs). In this study, partial colonic obstruction was induced by ligation. The neurons projecting to the colon were traced by an injection of 1,1'-dioctadecyl-3,3,3',3'-tetramethylindocarbocyanine perchlorate into the colon wall. The electrophysiological properties of DRG neurons were determined using intracellular electrodes. Dye coupling was examined with an intracellular injection of Lucifer yellow (LY). Morphological changes in the colon and DRG were examined. Pain was assessed with von Frey hairs. Partial colonic obstruction caused the following changes. First, coupling between SGCs enveloping different neurons increased 18-fold when LY was injected into SGCs near neurons projecting to the colon. Second, neurons were not coupled to other neurons or SGCs. Third, the firing threshold of neurons projecting to the colon decreased by more than 40% (P < 0.01), and the resting potential was more positive by 4-6 mV (P < 0.05). Finally, the number of neurons displaying spontaneous spikes increased eightfold, and the number of neurons with subthreshold voltage oscillations increased over threefold. These changes are consistent with augmented neuronal excitability. The pain threshold to abdominal stimulation decreased by 70.2%. Inflammatory responses were found in the colon wall. We conclude that obstruction increased neuronal excitability, which is likely to be a major factor in the pain behavior observed. The augmented dye coupling between glial cells may contribute to the neuronal hyperexcitability.

    Previous studies have demonstrated morphological and biomechanical remodeling in the intestine proximal to an obstruction. The present study aimed to obtain stress and strain thresholds to initiate contraction and the maximal contraction stress and strain in partially obstructed guinea pig jejunal segments. Partial obstruction and sham operations were surgically created in mid-jejunum of male guinea pigs. The animals survived 2, 4, 7 and 14 days. Animals not being operated on served as normal controls. The segments were used for no-load state, zero-stress state and distension analyses. The segment was inflated to 10 cmH(2)O pressure in an organ bath containing 37°C Krebs solution and the outer diameter change was monitored. The stress and strain at the contraction threshold and at maximum contraction were computed from the diameter, pressure and the zero-stress state data. Young's modulus was determined at the contraction threshold. The muscle layer thickness in obstructed intestinal segments increased up to 300%. Compared with sham-obstructed and normal groups, the contraction stress threshold, the maximum contraction stress and the Young's modulus at the contraction threshold increased whereas the strain threshold and maximum contraction strain decreased after 7 days obstruction (P<0.05 and 0.01). In conclusion, in the partially obstructed intestinal segments, a larger distension force was needed to evoke contraction likely due to tissue remodeling. Higher contraction stresses were produced and the contraction deformation (strain) became smaller.
