    The purpose of this study was to evaluate the accuracy of multi-detector row helical CT (MDCT) for detection and localization of acute upper and lower gastrointestinal (GI) hemorrhage or intraperitoneal bleeding. Thirty-six consecutive patients with clinical signs of acute bleeding underwent biphasic (16- or 40-channel) MDCT. MDCT findings were correlated with endoscopy, angiography or surgery. Among the 36 patients evaluated, 26 were examined for GI bleeding and 10 for intraperitoneal hemorrhage. Confirmed sites of GI bleeding were the stomach (n = 5), duodenum (n = 5), small bowel (n = 6), large bowel (n = 8) and rectum (n = 2). The correct site of bleeding was identifiable on MDCT in 24/26 patients with GI bleeding. In 20 of these 24 patients, active CM extravasation was apparent during the exam. Among the ten patients with intraperitoneal hemorrhage, MDCT correctly identified the bleeding source in nine patients. Our findings suggest that fast and accurate localization of acute gastrointestinal and intraperitoneal bleeding is achievable on MDCT. (orig.)

    Acute gastrointestinal bleeding is a common major emergency (Internal medical or gastroenterological or medical), approximately 85 % of which occur in the upper GI tract. It is estimated that about a half of upper GI bleeds are caused by peptic ulcers. Upper GI bleeds are associated with more severe bleeding and poorer outcomes when compared to middle or lower GI bleeds. Prognostic determinants include bleeding intensity, patient age, comorbid conditions and the concomitant use of anticoagulants. A focused medical history can offer insight into the bleeding intensity, location and potential cause (along with early risk stratification). Initial measures should focus on rapid assessment and resuscitation of unstable patients. The oesophagogastroduodenoscopy (OGD) is the gold standard method for localizing the source of bleeding and for interventional therapy. Bleeding as a result of peptic ulcers is treated endoscopically with mechanical and / or thermal techniques in combination with proton pump inhibitor (PPI) therapy. When variceal bleeding is suspected, pre-interventional use of vasopressin analogues and antibiotic therapies are recommended. Endoscopically, the first line treatment of esophageal varices is endoscopic ligature therapy, whereas that for gastric varices is the use of Histoacryl injection sclerotherapy. When persistent and continued massive hemorrhage occurs in a patient with known or suspected aortic disease the possibility of an aorto-enteric fistula must be considered. PMID:27078246

Patients were propensity-matched to AMI patients with no evidence of GI bleed from the same US health plan.Results: 12,437 upper GI-bleed patients and 22,847 AMI patients were identified. Propensity score matching yielded 6,923 matched pairs. Matched cohorts were found to have a similar Charlson Comorbidity Index score and to be similar on nearly all utilization and cost measures (excepting emergency room costs. A comparison of outcomes among the matched cohorts found that AMI patients had higher rates of 30-day mortality (4.35% vs 2.54%; p < 0.0001 and rehospitalization (2.56% vs 1.79%; p = 0.002, while GI bleed patients were more likely to have a repeat procedure (72.38% vs 44.95%; p < 0.001 following their initial hospitalization. The majority of the difference in overall 30-day mortality between GI bleed and AMI patients was accounted for by mortality during the initial hospitalization (1.91% vs 3.58%.Conclusions: GI bleeding events result in significant mortality similar to that of an AMI after adjusting for the initial hospitalization.Keywords: gastrointestinal, bleeding, mortality, acute myocardial infarction, claims analysis

  5. Scintigraphic diagnosis of lower GI bleeding

    International Nuclear Information System (INIS)

    Abdominal scintigraphy with 99mTc HSA, 99mTc Sn colloid, or 99mTc RBC was performed in 28 patients with melena to detect bleeding and determine the bleeding site in the lower gastrointestinal tract. Active bleedings and/or vascular lesions were identified in 16 patients. They were proved by antiography, endoscopy or barium enema in 14. We concluded that scintigraphy was an accurate and effective method to detect the bleeding and determine the bleeding site in the lower gastrointestinal tract. (author)

    To evaluate the incidence, predictive factors, and clinical outcomes of angiographically negative acute arterial upper and lower gastrointestinal (GI) bleeding. From 2001 to 2008, 143 consecutive patients who underwent an angiography for acute arterial upper or lower GI bleeding were examined. The angiographies revealed a negative bleeding focus in 75 of 143 (52%) patients. The incidence of an angiographically negative outcome was significantly higher in patients with a stable hemodynamic status (p < 0.001), or in patients with lower GI bleeding (p = 0.032). A follow-up of the 75 patients (range: 0-72 months, mean: 8 {+-} 14 months) revealed that 60 of the 75 (80%) patients with a negative bleeding focus underwent conservative management only, and acute bleeding was controlled without rebleeding. Three of the 75 (4%) patients underwent exploratory surgery due to prolonged bleeding; however, no bleeding focus was detected. Rebleeding occurred in 12 of 75 (16%) patients. Of these, six patients experienced massive rebleeding and died of disseminated intravascular coagulation within four to nine hours after the rebleeding episode. Four of the 16 patients underwent a repeat angiography and the two remaining patients underwent a surgical intervention to control the bleeding. Angiographically negative results are relatively common in patients with acute GI bleeding, especially in patients with a stable hemodynamic status or lower GI bleeding. Most patients with a negative bleeding focus have experienced spontaneous resolution of their condition.

    Various embolic agents have been used for embolization of acute gastrointestinal (GI) arterial bleeding. N-butyl cyanoacrylate (NBCA) is not easy to handle, but it is a useful embolic agent. In this retrospective study, we describe our experience with NBCA embolization of acute gastroduodenal ulcer bleeding. NBCA embolization was performed in seven patients with acute upper GI arterial bleeding; they had five gastric ulcers and two duodenal ulcers. NBCA embolization was done in the left gastric artery (n = 3), right gastric artery (n = 2), gastroduodenal artery (n = 1) and pancreaticoduodenal artery (n = 1). Coil was used along with NBCA in a gastric bleeding patient because of difficulty in selecting a feeding artery. NBCA was mixed with Lipiodol at the ratio of 1:1 to 1:2. The blood pressure and heart rate around the time of embolization, the serial hemoglobin and hematocrit levels and the transfusion requirements were reviewed to evaluate hemostasis and rebleeding. Technical success was achieved in all the cases. Two procedure-related complications happened; embolism of the NBCA mixture to the common hepatic artery occurred in a case with embolization of the left gastric artery, and reflux of the NBCA mixture occurred into the adjacent gastric tissue, but these did not cause any clinical problems. Four of seven patients did not present with rebleeding, but two had rebleeding 10 and 16 days, respectively, after embolization and they died of cardiac arrest at 2 months and 37 days, respectively. One other patient died of sepsis and respiratory failure within 24 hours without rebleeding. NBCA embolization with or without other embolic agents could be safe and effective for treating acute gastroduodenal ulcer bleeding.

    To report our experiences of transarterial embolization for acute intercostal artery bleeding. A retrospectively analysis of the causes, clinical manifestations, angiographic findings and transarterial embolization technique in 8 patients with acute intercostal artery bleeding, with a review of the anatomical basis. The causes of intercostal artery bleeding were iatrogenic and traumatic in 88 and 12% of cases, respectively. Active bleeding from the collateral intercostal or posterior intercostal arteries was angiographically demonstrated in 75 and 25% of cases, respectively. Transarterial embolization successfully achieved hemostasis in all cases. However, two patient with hypovolemic shock expired due to a massive hemothorax, despite successful transarterial embolization. Intercostal access should be performed through the middle of the intercostal space to avoid injury to the collateral intercostal artery. Transarterial embolization is an effective method for the control of intercostal artery bleeding.

  14. Studies of GI bleeding with scintigraphy and the influence of vasopressin

    International Nuclear Information System (INIS)

    The management of patients with gastrointestinal (GI) bleeding depends on accurate localization of the site of hemorrhage. Endoscopy and arteriography, although successful in achieving this goal in the majority of patients, are invasive and have other shortcomings. The introduction of the 99mTc-sulfur colloid technique has greatly simplified the evaluation and management of these patients. This test is useful in detecting and localizing the bleeding site in the lower GI tract. Scintigraphy is now used as the initial study of choice in patients with rectal bleeding. Advances made in angiography and nuclear medicine techniques also have resulted in improved management of patients. Conservative approaches succeed in controlling hemorrhage in most patients. Vasopressin is the most widely tested agent and has been adopted by many as the preferred preparation for this purpose. Before the introduction of the 99mTc-sulfur colloid technique, angiography was used to monitor the effectiveness of this drug, whether administered intravenously or intraarterially. With the use of scintigraphy and intravenous administration of vasopressin, these patients now can be managed noninvasively. Only when the intravenous Pitressin infusion fails to stop hemorrhage, is the intraarterial approach considered. Surgery is used as a last resort when these measures fail to stop the bleeding

  16. Detection of acute gastrointestinal bleeding by intra-arterial scintigraphy: an experimental study and preliminary clinical experience

    International Nuclear Information System (INIS)

    The purpose of this animal and clinical study was to compare intra-arterial (IA) scintigraphy with angiography in the localization of gastrointestinal (GI) bleeding. After sedation with intramuscularly administered ketamine, lower GI bleeding was induced in ten rabbits. Using inguinal cut-down, an arterial femoral 3F catheter was placed in the proximal mesenteric artery. Following abdominal incision to expose the bowel, lower GI bleeding was caused by incising the antimesenteric border of the small bowel wall. Initial angiography was performed, and this was followede by Tc-99m pertechnetate IA scintigarphy. Tc-99m RBC IA scintigraphy involved two patients who had undergone selective mesenteric arterial catheterizaion for the evaluation of acute lower GI bleeding. Ten rabbits, bleeding at a mean rate of 0.7g/min, were studied. IA scintigraphy was superior to angiography in four cases and equal in six. The sensitivity of angiography was 40%(4/10), and IA scintigraphy 80%(8/10). In one patient, Tc-99m RBC was administered directly into the superior mesenteric artery and ulcer bleeding in the transverse colon was identified. PRior to conventional angiography, the bleeding had been occult. In a second patient, in whom angiography had revealed a hypervascular mass, selective injection of Tc-99m RBC into the superior mesenteric artery revealed tumor(leiomyoma) bleeding in the jejunum. Selective IA scintigraphy was valuable for detecting intestinal bleeding, occult during conventional studies and may be useful for detecting acute bleeding at the time of negative angiography.=20

    Intravenously injected /sup 99m/Tc-DTPA was evaluated in 64 patients for its efficiency in detecting and localizing sites of acute upper and lower gastrointestinal (G.I.) bleeding. These studies were correlated with endoscopic and surgical findings. There were 34 bleeders and 30 non bleeders giving a sensitivity of 90%, specificity of 82% and accuracy of 86%. Of these, 49 were upper G.I. studies (stomach 21 and duodenum 28) and 15 were lower G.I. studies (small intestine 8, large bowel 7). Of the 49 upper G.I. studies, 27 showed active bleeding while 22 showed no bleeding at the time of the study resulting in a sensitivity of 87.5%, specificity of 76% and accuracy of 82%. Of the 15 lower G.I. studies, 7 were bleeders while 8 were non bleeders. All the lower G.I. bleeding sites were accurately localized with the /sup 99m/Tc-DTPA. An incidental finding of these studies was the localization of /sup 99m/Tc-DTPA in the site of inflammatory and malignant lesions of the G.I. tract. Of the 64 studies, 18 inflammatory and malignant lesions were detected with the IV injected /sup 99m/Tc-DTPA; 10 were bleeders while 8 were non bleeders. Image subtraction of early from delayed images was helpful to differentiate bleeding from non bleeding cases in this last group of studies.

    In most patients with upper gastrointestinal (GI) bleeding, endoscopy will locate the site and cause of bleeding, and also provide an opportunity for local therapy. The cause of lower GI bleeding is often difficult to attribute, even when pathology is found by colonoscopy or barium enema. Nuclear medicine techniques can be used to identify the site of bleeding in those patients in whom the initial diagnostic procedures are negative or inconclusive. Methods using transient labelling of blood (e.g. [sup 99]Tc[sup m]-sulphur colloid) produce a high target-to-background ratio in positive cases, give quick results and localize bleeding sites accurately, but depend upon bleeding being active at the time of injection. Techniques using stable blood labelling (e.g. [sup 99]Tc[sup m]-labelled red blood cells) may be positive even with intermittent bleeding but may take several hours to produce a result and are less precise in localization. The most useful application is in patients with recurrent or prolonged bleeding, those with inconclusive endoscopy or barium studies, and those who are high-risk surgical candidates. (author).

    Left-sided portal hypertension (LSPH) followed by acute pancreatitis is a rare condition with most patients being asymptomatic.In cases where gastrointestinal (GI) bleeding is present,however,the condition is more complicated and the mortality is very high because of the difficulty in diagnosing and selecting optimal treatment.A successfully treated case with severe GI bleeding by transcatheter splenic artery embolization is reported in this article.The patient exhibited severe uncontrollable GI bleeding and was confirmed as gastric varices secondary to LSPH by enhanced computed tomography (CT) scan and CT-angiography.After embolization,the bleeding stopped and stabilized for the entire follow-up period without any severe complications.In conclusion,embolization of the splenic artery is a simple,safe,and effective method of controlling gastric variceal bleeding caused by LSPH in acute pancreatitis.

  3. Interventional angiography in the diagnosis of acute lower gastrointestinal bleeding

    International Nuclear Information System (INIS)

    Interventional angiography with the use of indwelling arterial catheters, anticoagulants, vasodilators and fibrinolytic agents, complements conventional angiography in the diagnosis of acute lower gastrointestinal bleeding. These interventional techniques prolong, augment or reactive bleeding and, by enabling better timing of examinations, they increase the diagnostic efficacy of angiography. In the reported series of 63 patients with acute lower gastrointestinal hemorrhage, interventions increased the diagnostic yield of angiography for demonstration of extravasation from 32% to 65% and decreased the percentage of negative angiograms from 27% to 16%. Indications, techniques and risks of interventional angiography in the diagnosis of acute lower gastrointestinal bleeding are discussed. (orig.)

    This communication deals with the emergency control of variceal bleeding rather than the prevention of rebleeding. The current main options of oesophageal tamponade, emergency sclerotherapy and drug therapy are discussed, with particular reference to the use of somatostatin. Sandostatin (Sandoz, Basel), a synthetic long-acting somatostatin analogue, was found to reduce transhepatic venous gradient by 30% with no effect on systemic haemodynamics in a study of 16 stable cirrhotic patients. In a trial comparing intravenous infusion of Sandostatin (SMS) to oesophageal tamponade (OT) in active variceal bleeding, 18 of 20 bleeds in the SMS group and 19 of 20 bleeds in the OT group were controlled at 4 h. Ten in the SMS group and 14 in the OT group had no further bleeding during the 48-hour study period. Thus SMS may be useful in the temporary control of active variceal bleeding. PMID:8359565

It was known that he had a Zenker′s diverticulum, but on emergency endoscopy, the source of bleeding was not detected due to large blood clots in the esophagus, hypo-pharynx and also into the tracheal-bronchial tree. Computerized tomography angiography demonstrated a blush of intravenous contrast arising from the diverticulum. The patient was operated upon urgently; the diverticle had a deep ulceration which was the source of the bleeding. The cause of the ulceration is unknown but it is possible that it was caused by the direct effect of an aspirin pill within the diverticle. A similar case with the same conclusion has been published in the past and since the use of aspirin has become common, especially in the elder population, we present this case report to highlight this possible life-threatening complication of Zenker′s diverticulum in patients receiving aspirin.

    Full Text Available Abstract Background Isolated splenic vein thrombosis with left sided portal hypertension is a rare cause of upper gastrointestinal bleed. Diagnosis is difficult and requires a high index of suspicion, especially in patients presenting with gastrointestinal bleed in the presence of splenomegaly and normal liver function tests. Case presentation A 64 year old male presented with haematemesis and melaena. An upper gastrointestinal endoscopy revealed the presence of antral erosions in the stomach and fundal varices. A computerised tomography scan of abdomen confirmed the presence of a diaphragmatic tear and the spleen to be lying in the left hemi thorax. The appearances of the splenic vein on the scan were consistent with thrombosis. Conclusion Left sided portal hypertension as a result of isolated splenic vein thrombosis secondary to trauma is rare. The unusual presentation of our case, splenic herniation into the left hemithorax, causing fundal varices leading to upper gastrointestinal bleed 28 years after the penetrating injury, makes this case most interesting. We believe that this has not been reported in literature before.

    The objective of this study was to review the outcome of endovascular transcatheter repair of emergent arterioenteric fistulas. Cases of abdominal arterioenteric fistulas (defined as a fistula between a major artery and the small intestine or colon, thus not the esophagus or stomach), diagnosed....... All had massive persistent bleeding with hypotension despite volume substitution and transfusion by the time of endovascular management. Outcome after treatment of these patients was investigated for major procedure-related complications, recurrence, reintervention, morbidity, and mortality. Mean...... reintervention. The in-hospital mortality was 20% and the 30-day mortality was 40%. The midterm outcome was poor, due to comorbidities or rebleeding, with a mortality of 80% within 6 months. In conclusion, endovascular repair is an efficient and safe method to stabilize patients with life-threatening bleeding...

  10. Transcatheter embolization for treatment of acute lower gastrointestinal bleeding

    International Nuclear Information System (INIS)

    Treatment of lower gastrointestinal bleeding was attempted in 13 patients by selective embolization of branches of the mesenteric arteries with Gelfoam. Bleeding was adequately controlled in 11 patients with active bleeding during the examination. One patient improved after embolization but bleeding recurred within 24 hours and in another patient the catheterization was unsuccessful. Five patients with diverticular hemorrhage were embolized in the right colic artery four times, and once in the middle colic artery. Three patients had embolization of the ileocolic artery because of hemorrhage from cecal angiodysplasia, post appendectomy, and leukemia infiltration. Three patients had the superior hemorrhoidal artery embolized because of bleeding from unspecific proctitis, infiltration of the rectum from a carcinoma of the bladder, and transendoscopic polypectomy. One patient was septic and bled from jejunal ulcers. Ischemic changes with infarction of the large bowel developed in two patients and were treated by partial semi-elective colectomy, three and four days after embolization. Four other patients developed pain and fever after embolization. Transcatheter embolization of branches of mesenteric arteries in an effective way to control acute lower gastrointestinal bleeding, but still has a significant rate of complications that must be seriously weighed against the advantages of operation.

  13. The Management of Acute Upper Gastrointestinal Bleeding: A Comparison of Current Clinical Guidelines and Best Practice

    Full Text Available Acute upper gastrointestinal bleeding (AUGIB is the most common GI emergency, responsible for up to 70,000 hospital admissions in the UK and around 4,000 deaths. The latest UK national audit highlighted inconsistencies in both the management and service provision. Several national and international professional bodies have produced evidence-based recommendations on the management of AUGIB. We carried out a review of the guidance documentation published by four expert bodies including the National Institute of Clinical Excellence, the Scottish Intercollegiate Guidelines Network, the American College of Gastroenterology, and those published in the Annals of Internal Medicine. Consensus is still yet to be reached for initiating blood products in the emergency situation, with some evidence suggesting that liberal transfusion could exacerbate bleeding severity, although there is a lack of large randomised trials. It is widely agreed that prompt endoscopy within 24 hours improves outcomes, but evidence suggests that lowering this threshold confers no additional benefit. Use of proton pump inhibitors both pre and post-endoscopy for non-variceal bleeds is also advocated by professional bodies, with substantial evidence that it reduces the risk of re-bleeding. For patients with suspected oesophageal or gastric variceal bleeding, prophylactic antibiotics and vasopressin analogues are recommended, although guidelines vary on specific regimens. Recent UK and international guidelines provide a useful framework to guide management of patients who present to the emergency department with suspected AUGIB; however, their advice varies in some key areas due to a lack of large randomised trials as supporting evidence.

  14. Localization of bleeding using 4-row detector-CT in patients with clinical signs of acute gastrointestinal hemorrhage

    International Nuclear Information System (INIS)

    Purpose: There is no gold-standard regarding the diagnostic work-up and therapy of an acute gastrointestinal (GI) hemorrhage. In most cases endoscopy provides the diagnosis but in a low percentage this modality is not feasible or negative. Purpose of this study was to evaluate the role of multi-phase Multi-Slice-Computertomography (MSCT) as a modality to diagnose and locate the site of acute GI hemorrhage in case of unfeasible or technically difficult endoscopy. Materials and methods: 58 patients, presenting with clinical signs of lower GI hemorrhage, were examined through a 24-month period. Preliminary endoscopy was either negative or unfeasible. Images were obtained with a four-detector row CT with an arterial (4 x 1 mm collimation, 0.8 mm increment, 1.25 mm slice width, 120 kV, 165 mAs) and portal venous series (4 x 2,5 mm collimation, 2 mm increment, 3 mm slice width, 120 kV, 165 mAs). Time interval between endoscopy and CT varied between 30 minutes and 3 hours. The results of the MSCT were correlated with clinical course and surgical or endoscopical treatment. Results: 20 of the 58 patients (34%) undergoing MSCT had a bleeding site identified, thus providing decisive information for the following intervention. In case of a following therapeutic intervention there was 100% correlation regarding the bleeding site. In 38 of the 58 patients (66%), a bleeding site was not identified by MSCT. Twenty of these 38 patients (53%) were stable and required no further treatment. In 18 of these 38 patients further interventional therapy was required due to continuing hemorrhage and in all of those patients the bleeding site was detected by intervention. (orig.)

  15. Bleeding rates necessary for detecting acute gastrointestinal bleeding with technetium-99m-labeled red blood cells in an experimental model

    International Nuclear Information System (INIS)

    Proponents of [/sup 99m/Tc]sulfur colloid for GI bleeding studies argue that, although labeled red blood cells are useful for intermittent bleeding, they are not capable of detecting low bleeding rates. Studies of dogs with experimental GI bleeding have indicated bleeding rates of 0.05 ml/min can be detected with [/sup 99m/Tc]sulfur colloid. Since similar data in the dog model were unavailable for /sup 99m/Tc-labeled red blood cells, we undertook this study. To simulate lower GI bleeding, catheters were inserted into the bowel lumen. Each dog's blood was labeled with /sup 99m/Tc using an in vitro technique. Venous blood was then withdrawn and re-infused into the lumen of the bowel using a Harvard pump. Fourteen dogs were studied, ten receiving a bleeding rate from 4.6-0.02 ml/min in the descending colon and four with proximal jejunal bleeds of 0.20-0.02 ml/min. Bleeding rates of 4.6-0.2 ml/min were detected within 10 min in the colon and bleeding rates as low as 0.04 ml/min were seen by 55 min. Slower bleeding rates were not detected. Similar findings were noted for proximal jejunal bleeds. Based on the time of appearance, a minimum volume of approximately 2-3 ml labeled blood was necessary to detect bleeding. We conclude that /sup 99m/Tc-labeled RBCs are sensitive for low bleeding rates in the dog model. The rates are comparable to those described for [/sup 99m/Tc]sulfur colloid in this experimental setting. The time of appearance of activity is related to the bleeding rate

  16. Scintigraphic detection and localization of gastrointestinal bleeding sites

    International Nuclear Information System (INIS)

    Successful management of acute gastrointestinal (GI) bleeding usually depends on accurate localization of the bleeding site. History and clinical findings are often misleading in determination of the site of hemorrhage. The widespread application of flexible endoscopy and selective arteriography now provide accurate diagnoses for the majority of patients bleeding from the upper GI tract, but lower GI bleeding still poses a serious diagnostic challenge. Endoscopy and barium studies are of limited value in examining the small bowel and colon in the face of active hemorrhage. Arteriography, although successful in many cases (3-5), has limitations. The angiographic demonstration of bleeding is possible only when the injection of contrast material coincides with active bleeding at a rate greater than 0.5 ml/min, and since lower GI bleeding is commonly intermittent rather than continuous, a high rate of negative angiographic examinations has been reported. The diagnosis of lower GI bleeding is usually easy to make. In contrast, localizing the site of bleeding may be extremely difficult. Using the techniques described the nuclear physician may be able to detect the bleeding site precisely. However, if the cautions detailed are not observed, the tracer studies will show GI bleeding, but not at the true bleeding site. This must be carefully understood and avoided. Done correctly, these tests can have a major impact on patient care

    We wanted to evaluate the safety and effectiveness of superselective transarterial embolization for the management of gastrointestinal bleeding. We evaluated 97 of 115 patients who had undergone diagnostic angiography and transarterial embolization for gastrointestinal bleeding from February 2001 to July 2004, and they subsequently underwent superselective transarterial embolization. Their ages ranged from 17 to 88 years (mean age: 58.5 years), and 73 were men and 24 were women. The etiologies were a postoperative condition (n=31), ulcer (n=23), Mallory-Weiss syndrome (n=3), trauma (n=3), pseudoaneurysm from pancreatitis (n=3), diverticula (n=2), inflammatory bowel disease (n=2), tumor (n=2), Behcet's disease (n=2), hemobilia (n=1), and unknown origin (n=25). The regions of bleeding were the esophagus (n=3), stomach and duodenum (n=41), small bowel (n=38) and colon (n=15). All the patients underwent superselective transarterial embolization using microcoils, gelfoam or a combination of microcoils and gelfoam. Technical success was defined as devascularization of targeted vascular lesion or the disappearance of extravasation of the contrast media, as noted on the angiography after embolization. Clinical success was defined as the disappearance of clinical symptoms and the reestablishment of normal cardiovascular hemodynamics after transarterial embolization without any operation or endoscopic management. The technical success rate was 100%. The primary clinical success rate was 67% (65 of 97 patients). Of the 32 primary failures, fourteen patients underwent repeat embolization; of these, clinical success was achieved in all the patients and so the secondary clinical success rate was 81% (79 of 97 patients). Of the 18 patients with primary failures, five patients underwent operation, one patient underwent endoscopic management and the others died during the observation period due to disseminated coagulopathy or complications of their underlying diseases.

    The safety and clinical effectiveness of transcatheter arterial embolization for bleeding associated with unresectable gastric cancer was evaluated. Twenty-three patients with bleeding from unresectable gastric cancer underwent transcatheter arterial embolization. Of the 23 patients, eight showed signs of active bleeding, such as contrast extravasation or pseudoaneurysm, seven showed only tumor staining, and the remaining eight patients showed negative angiographic findings. All embolization procedures were successful without procedure-related complications. In all eight active bleeding patients, immediate hemostasis was achieved. The overall clinical success rate was 52% (12/23). Recurrent bleeding within 1 month occurred in one (8%) in 12 patients with initial clinical success. One patient showed partial splenic infarction after embolization of the splenic artery for active bleeding from the short gastric artery. Overall 30-day mortality rate was 43% (10/23). The median overall survival period was 38 days. In patients with bleeding from unresectable gastric cancer, transcatheter arterial embolization was found to be safe and effective for achieving immediate hemostasis for active bleeding. Although the clinical success rate was not high, the recurrent bleeding rate was low at 1 month post procedure. (orig.)

    To determine the cumulative incidence of acute upper gastrointestinal bleeding and its effect upon survival in patients with AIDS, 453 consecutive AIDS patients diagnosed in our hospital between June 1985 and March 1989 were followed for a median period of six months (maximum 42 months). The cumulative probability of acute gastrointestinal bleeding was 3% at six months and 6% at 14 months. This event was associated with significantly reduced survival. Independent risk factors for bleeding were: severe thrombocytopenia at the time of diagnosis and non-Hodgkin's lymphoma as the first clinical manifestation of AIDS. The potential causes of bleeding were investigated in all cases by emergency endoscopy or by necropsy examination in those patients whose clinical condition precluded the procedure. In nine of 15 patients, bleeding was due to lesions specifically associated with AIDS, but in the remainder the source of bleeding was not a direct consequence of HIV infection. We conclude that acute upper gastrointestinal bleeding rarely complicates the course of AIDS, but its occurrence is associated with decreased survival. As many of the causes are potentially treatable, a complete diagnostic approach is indicated in these patients, except those who are terminally ill. PMID:1916503

    Acute upper gastrointestinal bleedings from ulcers or esophago-gastric varices are life threatening medical conditions which require immediate endoscopic therapy. Despite successful endoscopic hemostasis, there is a significant risk of rebleeding often requiring close surveillance of these patients in the intensive care unit (ICU). Any time delay to recognize bleeding may lead to a high blood loss and increases the risk of death. A novel telemetric real-time bleeding sensor can help indicate blood in the stomach: the sensor is swallowed to detect active bleeding or is anchored endoscopically on the gastrointestinal wall close to the potential bleeding source. By telemetric communication with an extra-corporeal receiver, information about the bleeding status is displayed. In this study the novel sensor, which measures characteristic optical properties of blood, has been evaluated in an ex-vivo setting to assess its clinical applicability and usability. Human venous blood of different concentrations, various fluids, and liquid food were tested. The LED-based sensor was able to reliably distinguish between concentrated blood and other liquids, especially red-colored fluids. In addition, the spectrometric quality of the small sensor (size: 6.5mm in diameter, 25.5mm in length) was comparable to a much larger and technically more complex laboratory spectrophotometer. The experimental data confirm the capability of a miniaturized sensor to identify concentrated blood, which could help in the very near future the detection of upper gastrointestinal bleeding and to survey high-risk patients for rebleeding.

    Major bleeding is currently one of the most common non-cardiac complications observed in the treatment of patients with acute coronary syndrome(ACS). Hemorrhagic complications occur with a frequency of 1% to 10% during treatment for ACS. In fact, bleeding events are the most common extrinsic complication associated with ACS therapy. The identification of clinical characteristics and particularities of the antithrombin therapy associated with an increased risk of hemorrhagic complications would make it possible to adopt prevention strategies, especially among those exposed to greater risk. The international societies of cardiology renewed emphasis on bleeding risk stratification in order to decide strategy and therapy for patients with ACS. With this review, we performed an update about the ACS bleeding risk scores most frequently used in daily clinical practice.

    AIM: To study the prevalence, predictors and control of bleeding following N-butyl 2 cyanoacrylate (NBC)sclerotherapy of gastric varix (GV).METHODS: We analyzed case records of 1436 patients with portal hypertension, who underwent endoscopy during the past five years for variceal screening or upper gastrointestinal (GI) bleeding. Fifty patients with bleeding GV underwent sclerotherapy with a mean of 2 mL NBC for control of bleeding. Outcome parameters were primary hemostasis (bleeding control within the first 48 h), recurrent bleeding (after 48 h of esophagogastro-duodenoscopy) and in-hospital mortality were analyzed.RESULTS: The prevalence of GV in patients with portal hypertension was 15% (220/1436) and the incidence of bleeding was 22.7% (50/220). Out of the 50 bleeding GV patients, isolated gastric varices (IGV-Ⅰ) were seen in 22 (44%), gastro-oesophageal varices (GOV) on lesser curvature (GOV-Ⅰ ) in 16 (32%), and GOV on greater curvature (GOV-Ⅱ) in 15 (30%). IGV- Ⅰ was seen in 44% (22/50) patients who had bleeding as compared to 23% (39/170) who did not have bleeding (P <0.003). Primary hemostasis was achieved with NBC in all patients. Re-bleeding occurred in 7 (14%) patients after 48 h of initial sclerotherapy. Secondary hemostasis was achieved with repeat NBC sclerotherapy in 4/7(57%). Three patients died after repeat sclerotherapy,one during transjugular intrahepatic portosysternic stem shunt (TIPSS), one during surgery and one due to uncontrolled bleeding. Treatment failure-related mortality rate was 6% (3/50).CONCLUSION: GV can be seen in 15% of patients with portal hypertension and the incidence of bleeding is 22.7%. NBC is highly effective in controlling GV bleeding.In hospital mortality of patients with bleeding GV is 6%.

    Acute upper gastrointestinal bleeding (UGIB) is a gastroenterological emergency with a mortality of 6%-13%.The vast majority of these bleeds are due to peptic ulcers.Nonsteroidal anti-inflammatory drugs and Helicobacter pylori are the main risk factors for peptic ulcer disease.Endoscopy has become the mainstay for diagnosis and treatment of acute UGIB,and is recommended within 24 h of presentation.Proton pump inhibitor (PPI) administration before endoscopy can downstage the bleeding lesion and reduce the need for endoscopic therapy,but has no effect on rebleeding,mortality and need for surgery.Endoscopic therapy should be undertaken for ulcers with high-risk stigmata,to reduce the risk of rebleeding.This can be done with a variety of modalities.High-dose PPI administration after endoscopy can prevent rebleeding and reduce the need for further intervention and mortality,particularly in patients with high-risk stigmata.

    Highlights: • We report our experiences with stent-grafts for the treatment of acute hemorrhage from the hepatic artery or the stump of the gastroduodenal artery. • The technical success of stent-graft implantation was 88%. • The bleeding ceased immediately after stent-graft implantation in 88%. • The complication rate was 21%. - Abstract: Purpose: We evaluated the technical success and clinical efficacy of stent-graft implantation for the emergency management of acute hepatic artery bleeding. Methods: Between January 2010 and July 2013, 24 patients with hemorrhage from the hepatic artery were scheduled for emergency implantation of balloon expandable stent-grafts. The primary study endpoints were technical and clinical success, which were defined as successful stent-graft implantation with sealing of the bleeding site at the end of the procedure, and cessation of clinical signs of hemorrhage. The secondary study endpoints were complications during the procedure or at follow-up and 30-day mortality rate. Results: In 23 patients, hemorrhage occurred after surgery, and in one patient hemorrhage occurred after trauma. Eight patients had sentinel bleeding. In most patients (n = 16), one stent-graft was implanted. In six patients, two overlapping stent-grafts were implanted. The stent-grafts had a target diameter between 4 mm and 7 mm. Overall technical success was 88%. The bleeding ceased after stent-graft implantation in 21 patients (88%). The mean follow-up was 137 ± 383 days. In two patients, re-bleeding from the hepatic artery occurred during follow-up after 4 and 29 days, respectively, which could be successfully treated by endovascular therapy. The complication rate was 21% (minor complication rate 4%, major complication rate 17%). The 30-day mortality rate was 21%. Conclusions: Implantation of stent-grafts in the hepatic artery is an effective emergency therapy and has a good technical success rate for patients with acute arterial hemorrhage.

    Results of antisecretory therapy (pyrenzepin, H(2)-blockers, inhibitors of proton pump, octreotid) in 962 patients with acute gastroduodenal ulcer bleedings (AGDUB) were analyzed over 14-years period. Antisecretory treatment in AGDUB has principally different goals and potential depending on risk of bleeding's recurrence and morphological changes in tissue of gastroduodenal ulcer. Antisecretory therapy is the main treatment in high risk of AGDUB recurrence or before urgent surgery. Intravenous infusion of omeprazol has demonstrated the highest clinical efficacy due to maximal inhibition of gastric secretion and absence of negative influences on oxygen regimen in tissue of ulcer.

    2005-01-01

    The experience in diagnosis and treatment of bleeding complications in severe acute pancreatitis (SAP) by transcatheter arterial embolization was summarized. The clinical data of 19 SAP patients complicated with intra-abdominal bleeding in our hospital from Jan. 2000 to Jan. 2003 were analyzed retrospectively and the therapeutic outcome of TAE was evaluated statistically. The results showed that the short-term successful rate of hemostasis by TAE was 89.5 % (17/19), the incidence of re-bleeding after TAE was 36.8 % (7/19) and the successful rate of hemostatis by second TAE was 71.4 % (5/7). It was concluded that the intra-abdominal bleeding in SAP was mainly caused by the rupture of erosive/infected pseudoaneurysm. Mostly, the broken vessels were splenic artery and gastroduodenal artery. In terms of emergence hemostatis, TAE is the most effective method. Surgical hemostasis is necessary if hemostasis by TAE is failed or re-bleeding occurs after TAE.

    AIM: To prospectively assess the impact of time of endoscopy and endoscopist's experience on the outcome of non-variceal acute upper gastrointestinal (GI) bleeding patients in a large teaching hospital.METHODS: All patients admitted for non-variceal acute upper GI bleeding for over a 2-year period were potentially eligible for this study. They were managed by a team of seven endoscopists on 24-h call whose experience was categorized into two levels (high and low) according to the number of endoscopic hemostatic procedures undertaken before the study. Endoscopic treatment was standardized according to Forrest classification of lesions as well as the subsequent medical therapy. Time of endoscopy was subdivided into two time periods: routine (8 a.m.-5 p.m.) and on-call (5 p.m.-8 a.m.). For each category of experience and time periods rebleeding rate, transfusion requirement, need for surgery, length of hospital stay and mortality we compared. Multivariate analysis was used to discriminate the impact of different variables on the outcomes that were considered.RESULTS: Study population consisted of 272 patients (mean age 67.3 years) with endoscopic stigmata of hemorrhage. The patients were equally distributed among the endoscopists, whereas only 19% of procedures were done out of working hours. Rockall score and Forrest classification at admission did not differ between time periods and degree of experience.Univariate analysis showed that higher endoscopist's experience was associated with significant reduction in rebleeding rate (14% vs 37%), transfusion requirements (1.8±0.6 vs 3.0±1.7 units) as well as surgery (4% vs 10%), but not associated with the length of hospital stay nor mortality. By contrast, outcomes did not significantly differ between the two time periods of endoscopy.On multivariate analysis, endoscopist's experience was independently associated with rebleeding rate and transfusion requirements. Odds ratios for low experienced endoscopist were 4.47 for

    Full Text Available In the acute stage of pancreatitis, sinistral portal hypertension is a rare reason for gastric variceal bleeding. Here we report a 20-year-old female patient with massive upper gastrointestinal hemorrhage 7 days after an episode of severe acute pancreatitis. Computed tomography showed gastric varices caused by splenic venous thrombosis. Emergency endoscopic examination was performed, however tissue adhesive utilized to restrain the bleeding was not successful. Although interventional therapy was controversial to treat the gastric variceal hemorrhage resulting from sinistral portal hypertension, the bleeding was successfully treated by embolization of the splenic artery combined with short gastric vein. Two weeks after the interventional the patient was discharged from our hospital without recurrence of bleeding. Embolization of the splenic artery combined with short gastric vein proved to be an effective emergency therapeutic method for gastric variceal bleeding caused by sinistral portal hypertension in the acute stage of pancreatitis.

    Full Text Available The aim of the work was to estimate the intensity and tissue distribution of proapoptogen p53 expression in duodenal mucosa in patients with acute bleeding caused by peptic ulcers. In 31 patients (1st group the healing of ulcer was detected after effective endoscopic hemostasis and in 15 patients rebleeding took place (2nd group. Performed immunocytochemical investigation allow to determine that acute ulcer bleeding was associated with activation of marginal zone cells apoptosis which was maximal in covering epithelium, vascular endothelium and regions infiltrated by lymphocytes. In patients with rebleeding the higher values of р53 expression were detected in crypts epithelium and in endothelium of dilatating vessels accompanied with intensive edema and lymphocytes infiltration of lamina propria and muscularis mucosae with perifocal activation of cells death. Additionally to apoptosis in 2nd group duodenum the necrosis of cells and epithelium desquamation were found, reflecting the tissue disintegration of duodenal mucosa.

    Gastrointestinal (GI) tract is the most common site of extranodal lymphoma. Primary GI lymphoma constitutes a small amount of all lymphomas. Primary duodenal lymphoma presenting initially with obstructive jaundice is very rare. Primary B-cell lymphoma of the duodenum was shown to be the cause of biliary obstruction in a retropositive male, which was proved by endoscopic biopsy. Histopathology also showed cytomegalovirus inclusion bodies with duodenitis.

  4. Effect of Pseudomonas contamination or antibiotic decontamination of the GI tract on acute radiation lethality after neutron or gamma irradiation

    International Nuclear Information System (INIS)

    The influence of antibiotic decontamination of Pseudomonas contamination of the GI tract prior to whole-body neutron or gamma irradiation was studied. It was observed that for fission neutron doses greater than 5.5 Gy, cyclotron-produced neutron doses greater than 6.7 Gy, and 137Cs gamma-ray doses greater than 14.4 Gy, the median survival time of untreated rats was relatively constant at 4.2 to 4.5 days, indicating death was due to intestinal injury. Within the dose range of 3.5 to 5.5 Gy of fission neutrons, 4.9 to 6.7 Gy of cyclotron-produced neutrons, and 9.6 to 14.4 Gy of gamma rays, median survival time of these animals was inversely related to dose and varied from 12 to 4.6 days. This change in survival time with dose reflects a transition in the mechanisms of acute radiation death from pure hematopoietic, to a combination of intestinal and hematopoietic, to pure intestinal death. Decontamination of the GI tract with antibiotics prior to irradiation increased median survival time 1 to 5 days in this transitional dose range. Contamination of the intestinal flora with Pseudomonas aeruginosa prior to irradiation reduced median survival time 1 to 5 days in the same radiation dose range. Pseudomonas-contaminated animals irradiated within this transitional dose range had maximum concentrations of total bacteria and Pseudomonas in their livers at the time of death. However, liver bacteria concentration was usually higher in gamma-irradiated animals, due to a smaller contribution of hematopoietic injury in neutron-irradiated animals. The effects of both decontamination of the GI tract and Pseudomonas contamination of the GI tract were negligible in the range of doses in which median survival time was dose independent, i.e., in the pure intestinal death dose range

    In the Digestive Disease Week in 2015 there have been some new contributions in the field of gastrointestinal bleeding that deserve to be highlighted. Treatment of celecoxib with a proton pump inhibitor is safer than treatment with nonselective NSAID and a proton pump inhibitor in high risk gastrointestinal and cardiovascular patients who mostly also take acetylsalicylic acid. Several studies confirm the need to restart the antiplatelet or anticoagulant therapy at an early stage after a gastrointestinal hemorrhage. The need for urgent endoscopy before 6-12 h after the onset of upper gastrointestinal bleeding episode may be beneficial in patients with hemodynamic instability and high risk for comorbidity. It is confirmed that in Western but not in Japanese populations, gastrointestinal bleeding episodes admitted to hospital during weekend days are associated with a worse prognosis associated with delays in the clinical management of the events. The strategy of a restrictive policy on blood transfusions during an upper GI bleeding event has been challenged. Several studies have shown the benefit of identifying the bleeding vessel in non varicose underlying gastric lesions by Doppler ultrasound which allows direct endoscopic therapy in the patient with upper GI bleeding. Finally, it has been reported that lower gastrointestinal bleeding diverticula band ligation or hemoclipping are both safe and have the same long-term outcomes. PMID:26520197

    Acute lower gastrointestinal bleeding (LGIB) is a frequent gastrointestinal cause of hospitalization,particularly in the elderly,and its incidence appears to be on the rise.Endoscopic and radiographic measures are available for the evaluation and treatment of LGIB including flexible sigmoidoscopy,colonoscopy,angiography,radionuclide scintigraphy and multi-detector row computed tomography.Although no modality has emerged as the gold standard in the management of LGIB,colonoscopy is the current preferred initial test for the majority of the patients presenting with hematochezia felt to be from a colon source.Colonoscopy has the ability to diagnose all sources of bleeding from the colon and,unlike the radiologic modalities,does not require active bleeding at the time of the examination.In addition,therapeutic interventions such as cautery and endoclips can be applied to achieve hemostasis and prevent recurrent bleeding.Studies suggest that colonoscopy,particularly when performed early in the hospitalization,can decrease hospital length of stay,rebleeding and the need for surgery.However,results from available small trials are conflicting and larger,multicenter studies are needed.Compared to other management options,colonoscopy is a safe procedure with complications reported in less than 2% of patients,including those undergoing urgent examinations.The requirement of bowel preparation (typically 4 or more liters of polyethylene glycol),the logistical complexity of coordinating after-hours colonoscopy,and the low prevalence of stigmata of hemorrhage complicate the use of colonoscopy for LGIB,particularly in urgent situations.This review discusses the above advantages and disadvantages of colonoscopy in the management of acute lower gastrointestinal bleeding in further detail.

    Full Text Available Gastrointestinal (GI bleed often brings the patient to the emergency medical service with great anxiety. Known common causes of GI bleed include ulcers, varices, Mallory-Weiss among others. All causes of GI bleed should be considered however unusual during the evaluation. Aortoenteric fistula (AEF is one of the unusual causes of GI bleed, which has to be considered especially in patients with a history of abdominal surgery in general and aortic surgery in particular.

    Purpose: There is no gold-standard regarding the diagnostic work-up and therapy of an acute gastrointestinal (GI) hemorrhage. In most cases endoscopy provides the diagnosis but in a low percentage this modality is not feasible or negative. Purpose of this study was to evaluate the role of multi-phase Multi-Slice-Computertomography (MSCT) as a modality to diagnose and locate the site of acute GI hemorrhage in case of unfeasible or technically difficult endoscopy. Materials and methods: 58 patients, presenting with clinical signs of lower GI hemorrhage, were examined through a 24-month period. Preliminary endoscopy was either negative or unfeasible. Images were obtained with a four-detector row CT with an arterial (4 x 1 mm collimation, 0.8 mm increment, 1.25 mm slice width, 120 kV, 165 mAs) and portal venous series (4 x 2,5 mm collimation, 2 mm increment, 3 mm slice width, 120 kV, 165 mAs). Time interval between endoscopy and CT varied between 30 minutes and 3 hours. The results of the MSCT were correlated with clinical course and surgical or endoscopical treatment. Results: 20 of the 58 patients (34%) undergoing MSCT had a bleeding site identified, thus providing decisive information for the following intervention. In case of a following therapeutic intervention there was 100% correlation regarding the bleeding site. In 38 of the 58 patients (66%), a bleeding site was not identified by MSCT. Twenty of these 38 patients (53%) were stable and required no further treatment. In 18 of these 38 patients further interventional therapy was required due to continuing hemorrhage and in all of those patients the bleeding site was detected by intervention. (orig.)

    Objective Gastrointestinal(GI) bleeding is one of most serious complications after acute stage of ischemic stroke. This study is to investigate the risk factors as well as the prognosis of those cases with GI bleeding following acute stroke. Methods From Mar 2008 to Aug 2010, we prospectively collected ischemic stroke patients with or without GI bleeding in our intensive care unit grouped as research group and controls. A six month follow-up was conducted. Comparison was done between groups on the aspect of demography, predisposing factors and prognosis. Results Overall 3. 5% of GI bleeding was observed a-mong those ischemic stroke patients. The four major risk factors were coma ( 0R5.0 95% CI 1.4 ~ 17. 5 ) , incontinence ( OR5. 8 95% CI 1. 5 - 22. 2 ) , history of peptic ulcer or GI bleeding ( OR5. 2 95% CI 1. 3 ~ 21.1) and history of stroke ( OR3. 6 95% CI 1. 0 ~ 12. 7)respectively. During the follow-up, higher mortality rate was detected in research group (45. 5% ) especially those with sever GI bleeding (50% ) than that in controls (10% ). Conclusion Although GI bleeding is not a relative common complication after acute ischemic stroke, we should notice that it is associated with increased death risk. Thus we should be focused more attention on those risk factors.%目的 消化道出血是脑卒中后最严重的并发症之一.本研究探讨比较了其危险因素及相关预后.方法 收集2008年3月~2010年8月,我院重症监护室收治的脑梗死并发上消化道出血的患者(研究组)以及未并发上消化道出血的脑梗死患者(对照组),并进行6个月的随访.比较相关人口学数据、危险因素及相关预后.结果 研究发现,脑梗死并发消化道出血发生率为3.5%,其高危因素主要为昏迷(OR5.0 95% CI 1.4 ~ 17.5)、大小便失禁(OR5.8 95% CI1.5 ~22.2)、消化道溃疡或出血病史(OR5.2 95%CI 1.3 ~21.1)以及既往卒中病史(OR3.6 95%CI 1.0 ~ 12.7).在6个月的随访

  10. Effects of Pseudomonas contamination or antibiotic decontamination of the GI tract on acute radiation lethality

    International Nuclear Information System (INIS)

    The influence of antibiotic decontamination or Psuedomonas contamination of the GI tract prior to whole-body neutron or gamma irradiation was studied. For neutron doses greater than 6.7 Gy and gamma ray doses greater than 14.4 Gy, the median survival time of SPF rats was relatively constant at 4.4 days, indicating death was due to intestinal injury. Within the dose range of 4.9 to 6.7 Gy of neutrons or 9.6 to 14.4 Gy of photons, median survival time was inversely related to dose and varied from 12 to 4.6 days. Decontamination or Pseudomonas contamination of the GI tract increased or decreased, respectively, median survival time 1 to 5 days in this survival dose dependent range. The effects of these treatments, however, were negligible in the range of doses in which median survival time was dose independent. These treatments had little effect on the ultimate survival after irradiation as measured by either the LD50/5 day or LD50/30 day endpoints

  12. Detection and localization of lower gastrointestinal bleeding site with scintigraphic techniques

    International Nuclear Information System (INIS)

    Successful management of acute gastrointestinal (GI) bleeding frequently depends on accurate localization of the bleeding site. History and clinical findings are often misleading in localizing the site of hemorrhage. The widespread application of flexible endoscopy and selective arteriography now provides accurate diagnoses for the majority of patients with upper GI tract hemorrhage, but lower GI bleeding still is a serious diagnostic problem. Endoscopy and barium studies are of limited value in examining the small bowel and colon in the face of active hemorrhage. Arteriography, although successful in many cases, has limitations. The angiographic demonstration of bleeding is possible only when the injection of contrast material coincides with active bleeding. Since lower GI bleeding is commonly intermittent rather than continuous, a high rate of negative angiographic examinations has been reported. Repeated angiography to pursue recurrent episodes of bleeding is impractical. Because of these shortcomings, in the past decade several noninvasive scintigraphic techniques have been developed to detect and localize sites of GI bleeding. In this chapter the authors discuss details related to the technetium 99m sulfur colloid (Tc-SC) and technetium 99m-labeled red blood cell (Tc-RBC) techniques

    Men with testicular tumors usually present with painless increase in testis size incidentally noticed by the patient. We report a case of a young patient presenting as an emergency with acute onset of massive right-sided testicular pain without previous injury. After physical examination testicular torsion could not be excluded. Ultrasound examination of the tesds was suspicious for tesdcular tumor. Surgical exploration of the right testis by inguinal approach was performed revealing subcapsular arterial bleeding due to a small nonseminomatous germ cell tumor non-palpable on clinical examination.

    Background Octride was the main method for the treatment of esophageal variceal bleeding (EVB). The aim of this study was to compare the cost-effect and safety between esophageal variceal ligation (EVL) plus octride and octride alone in acute esophageal bleeding.Methods A total of 101 cirrhotic patients with EVB were involved in this study and received emergency EVL+octride (EVL group) or only octride therapy randomly. The cost, efficacy and safety were analyzed and compared between the two groups.Results Among 51 patients in EVL group, 5 (10%) patients failed. Among 50 patients in the octride treatment group, 13 patients (26%) failed. The difference was significant (P<0.05). The average blood transfusion volume was (2.4±2.2) units in the EVL group and (6.4±3.4) units in the octride treatment group (P <0.05). Hospital stay was (7.4±1.3) days in the EVL group and (11.4±3.3) days in the octride treatment group (P<0.05). The average hospital cost was (10 983±1147) yuan in the EVL group and (13 921 ±2107) yuan in the octride treatment group (P<0.05). Conclusion Emergency endoscopic ligation plus octride is superior to octride alone in the treatment of acute EVB with lower cost and higher efficacy with enough safety.

  16. Clinical outcomes of patients with major bleeding after primary coronary intervention for acute ST-segment elevation myocardial infarction

    International Nuclear Information System (INIS)

    Objective: To evaluate the clinical outcomes of patients complicated with major bleeding after primary coronary intervention (PCI) for acute ST-segment elevation myocardial infarction (STEMI). Methods: During the period of January 2004-January 2008, primary PCI was performed in 412 consecutive patients with acute STEMI at Shanghai Ruijin Hospital. The clinical data were retrospectively analyzed. Major adverse cardiac events (MACE), including death, reoccurrence of myocardial infarction and target vessel revascularization, in patients with major bleeding were compared with that in patients without major bleeding. Results: Compared to patients without bleeding, the patients with bleeding were older (70.0 ± 8.9 years vs 64.9 ± 12.7 years, P=0.04), mainly the females (51.9% vs 23.1%, P=0.001) and treated more often with glycoprotein (GP) IIb / IIIa receptor inhibitor (88.9% vs 69.4%, P=0.03) or intra-aortic balloon pump (7.4% vs 1.3%, P=0.02). In-hospital and one-year MACE rate in the patients with bleeding was 18.5% and 37.0% respectively,which were significantly higher than that in the patients without bleeding (5.7% and 14.3%, with P=0.008 and P=0.002, respectively). Multivariate analysis indicated that patient aged over 70 years, feminine gender and use of GP IIb/IIIa receptor inhibitor were independent predictors for the occurrence of major bleeding. The occurrence of major bleeding after primary PCI was significantly correlated with MACE occurred within one year after the procedure (OR 2.79, 95% CI: 2.21-5.90, P<0.001). Conclusion: In patients with acute STEMI, the occurrence of major bleeding after primary PCI is closely linked to the increased MACE rate within one year after the treatment.Feminine gender, aged patient and use of GPIIb/IIIa receptor inhibitor are independent predictors to increase the danger of major bleeding.

    BACKGROUND: Acute esophageal variceal bleeding (EVB) is a major cause of morbidity and mortality in patients with liver cirrhosis. Guidelines have been published in 1997; however, variability in the acute management and prevention of EVB rebleeding may occur. METHODS: Gastroenterologists in the provinces of British Columbia, Alberta, Manitoba and Saskatchewan were sent a self-reporting questionnaire. RESULTS: The response rate was 70.4% (86 of 122). Intravenous octreotide was recommended by 93% for EVB patients but the duration was variable. The preferred timing for endoscopy in suspected acute EVB was within 12 h in 75.6% of respondents and within 24 h in 24.6% of respondents. Most (52.3%) gastroenterologists do not routinely use antibiotic prophylaxis in acute EVB patients. The preferred duration of antibiotic therapy was less than three days (35.7%), three to seven days (44.6%), seven to 10 days (10.7%) and throughout hospitalization (8.9%). Methods of secondary prophylaxis included repeat endoscopic therapy (93%) and beta-blocker therapy (84.9%). Most gastroenterologists (80.2%) routinely attempted to titrate beta-blockers to a heart rate of 55 beats/min or a 25% reduction from baseline. The most common form of secondary prophylaxis was a combination of endoscopic and pharmacological therapy (70.9%). CONCLUSIONS: Variability exists in some areas of EVB treatment, especially in areas for which evidence was lacking at the time of the last guideline publication. Gastroenterologists varied in the use of prophylactic antibiotics for acute EVB. More gastroenterologists used combination secondary prophylaxis in the form of band ligation eradication and beta-blocker therapy rather than either treatment alone. Future guidelines may be needed to address these practice differences. PMID:16955150

    AIM: To evaluate the aetiology, clinical outcome and factors related to mortality of acute upper gastrointestinal bleeding (AUGIB) in octogenarians.METHODS: We reviewed the records of all patients over 65 years old who were hospitalised with AUGIB in two hospitals from January 2006 to December of 2006. Patients were divided into two groups: Group A (65-80 years old) and Group B (>80 years old).RESULTS: Four hundred and sixteen patients over 65 years of age were hospitalized because of AUGIB. Group A included 269 patients and Group B147 patients. Co-morbidity was more common in octogenarians (P=0.04). The main cause of bleeding was peptic ulcer in both groups. Rebleeding and emergency surgery were uncommon in octogenarians and not different from those in younger patients. In-hospital complications were more common in octogenarians (P=0.05) and more patients died in the group of octogenarians compared to the younger age group (P=0.02). Inability to perform endoscopic examination (P=0.002), presence of high risk for rebleeding stigmata (P=0.004), urea on admission (P=0.036), rebleeding (P=0.004) and presence of severe co-morbidity (P<0.0001) were related to mortality. In multivariate analysis, only the presence of severe co-morbidity was independently related to mortality (P=0.032).CONCLUSION: While rebleeding and emergency surgery rates are relatively low in octogenarians with AUGIB, the presence of severe co-morbidity is the main factor of adverse outcome.

    Currently we are no nearer than 10 or 20years ago providing a safe, adequate, and effective round-the-clock endoscopic services for acute life-threatening gastrointestinal bleeding in children. Preventable deaths are occurring still, and it is a tragedy. This is owing to a number of factors which require urgent attention. Skill-mix and the ability of available endoscopists in the UK are woeful. Manpower is spread too thinly and not concentrated in centers of excellence, which is necessary given the relative rarity of the presentation. Adult gastroenterologists are increasingly reticent regarding their help in increasingly litigious times. Recent work on identification of those children likely to require urgent endoscopic intervention has mirrored scoring systems that have been present in adult circles for many years and may allow appropriate and timely intervention. Recent technical developments such as that of Hemospray® may lower the threshold of competency in dealing with this problem endoscopically, thus allowing lives to be saved. Educational courses, mannequin and animal model training are important but so will be appropriate credentialing of individuals for this skill-set. Assessment of competency will become the norm and guidelines on a national level in each country mandatory if we are to move this problem from the "too difficult" to the "achieved". It is an urgent problem and is one of the last emergencies in pediatrics that is conducted poorly. This cannot and should not be allowed to continue unchallenged.

    Full Text Available Background - Upper gastrointestinal bleeding implies significant clinical and economic repercussions. The correct establishment of the latest therapies for the upper gastrointestinal bleeding is associated with reduced in-hospital mortality. The use of clinical pathways for the upper gastrointestinal bleeding is associated with shorter hospital stay and lower hospital costs. Objective - The primary objective is the development of a clinical care pathway for the management of patients with upper gastrointestinal bleeding, to be used in tertiary hospital. Methods - It was conducted an extensive literature review on the management of upper gastrointestinal bleeding, contained in the primary and secondary information sources. Results - The result is a clinical care pathway for the upper gastrointestinal bleeding in patients with evidence of recent bleeding, diagnosed by melena or hematemesis in the last 12 hours, who are admitted in the emergency rooms and intensive care units of tertiary hospitals. In this compact and understandable pathway, it is well demonstrated the management since the admission, with definition of the inclusion and exclusion criteria, passing through the initial clinical treatment, posterior guidance for endoscopic therapy, and referral to rescue therapies in cases of persistent or rebleeding. It was also included the care that must be taken before hospital discharge for all patients who recover from an episode of bleeding. Conclusion - The introduction of a clinical care pathway for patients with upper gastrointestinal bleeding may contribute to standardization of medical practices, decrease in waiting time for medications and services, length of hospital stay and costs.

    Full Text Available Objective: To review available evidence and examine issues surrounding the use of advanced antiplatelet therapy in an effort to provide a practical guide for emergency physicians caring for patients with acute coronary syndromes (ACS.Data Sources: American College of Cardiology/American Heart Association (ACC/AHA 2007 guidelines for the management of patients with unstable angina (UA and non-ST-segment elevation myocardial infarction (NSTEMI, AHA/ACC 2007 focused update for the management of patients with STEMI, selected clinical articles identified through the PubMed database (1965-February 2008, and manual searches for relevant articles identified from those retrieved.Study Selection: English-language controlled studies and randomized clinical trials that assessed the efficacy and safety of antiplatelet therapy in treating patients with all ACS manifestations.Data Extraction and Synthesis: Clinical data, including treatment regimens and patient demographics and outcomes, were extracted and critically analyzed from the selected studies and clinical trials. Pertinent data from relevant patient registries were also evaluated to assess current clinical practice.Conclusions: As platelet activation and aggregation are central to ACS pathology, antiplatelet agents are critical to early treatment. A widely accepted first-line treatment is aspirin, which acts to decrease platelet activation via inhibition of thromboxane A2 synthesis. Thienopyridines, which inhibit ADP-induced platelet activation, and glycoprotein (GP receptor antagonists, which bind to platelet GP IIb/IIIa receptors and hinder their role in platelet aggregation and thrombus formation, provide complementary mechanisms of platelet inhibition and are often employed in combination with aspirin. While the higher levels of platelet inhibition that accompany combination therapy improve protection against ischemic and peri-procedural events, the risk of bleeding is also increased. Thus, the

    The effects of a large intracranial arterial subdural bleeding on regional blood flow in the brain (rCBF) and in other body organs were studied, using a porcine model. The bleeding was produced by leading blood through a catheter from the abdominal aorta via an electronic drop recorder into the subdural compartment (SDC) over the left cerebral hemisphere. Pressures in the right lateral cerebral ventricle and in the cisterna magna were recorded along with 15 other vital parameters. Measurements of rCBF were carried out using radioactive microspheres 1) before the start of bleeding, 2) during the early bleeding phase, and 3) during the late bleeding phase. When the bleeding was initiated, the intracranial pressures rose within one minute to a level approximately 40 mmHg below the systemic arterial pressure, whilst the latter usually decreased 30-40 mmHg. In the subsequent early bleeding phase the cerebral perfusion pressure and the bleeding pressure fluctuated at a level of approximately 40 mmHg for several minutes. In the late bleeding phase, the perfusion pressure decreased maximally, even when a Cushing reaction was activated. During the early bleeding phase the changes in rCBF varied between the cerebral regions. However, the mean flow remained largely constant in the presence of a decreasing cerebrovascular resistance, indicating that autoregulation of CBF was intact. Concomitantly, cardiac output and heart rate decreased, whilst regional blood flow in extracerebral organs tended to increase, possibly due to an intracranial effect on the autonomic nervous system. In the late bleeding phase, rCBF was critically reduced in all regions, in spite of a marked rise in systemic arterial pressure.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:8372718

    AIM: Acute gastrointestinal bleeding is a severe complication in patients receiving long-term oral anticoagulant therapy.The purpose of this study was to describe the causes and clinical outcome of these patients.METHODS: From January 1999 to October 2003, 111patients with acute upper gastrointestinal bleeding (AUGIB)were hospitalized while on oral anticoagulants. The causes and clinical outcome of these patients were compared with those of 604 patients hospitalized during 2000-2001with AUGIB who were not taking warfarin.RESULTS: The most common cause of bleeding was peptic ulcer in 51 patients (45%) receiving anticoagulants compared to 359/604 (59.4%) patients not receiving warfarin (P<0.05). No identifiable source of bleeding could be found in 33 patients (29.7%) compared to 31/604(5.1%) patients not receiving anticoagulants (P= 0.0001).The majority of patients with concurrent use of non-steroidal anti-inflammatory drugs (NSATDs) (26/35, 74.3%) had a peptic ulcer as a cause of bleeding while 32/76 (40.8%)patients not taking a great dose of NSATDs had a negative upper and lower gastrointestinal endoscopy. Endoscopic hemostasis was applied and no complication was reported.Six patients (5.4%) were operated due to continuing or recurrent hemorrhage, compared to 23/604 (3.8%) patients not receiving anticoagulants. Four patients died, the overall mortality was 3.6% in patients with AUGIB due to anticoagulants, which was not different from that in patients not receiving anticoagulant therapy.CONCLUSION: Patients with AUGIB while on long-term anticoagulant therapy had a clinical outcome, which is not different from that of patients not taking anticoagulants.Early endoscopy is important for the management of these patients and endoscopic hemostasis can be safely applied.

    Aim. Helicobacter pylori (H. pylori) infection is exceptionally rare in population from the north-eastern region of Peninsular Malaysia. This provides us an opportunity to contemplate the future without H. pylori in acute non-variceal upper gastrointestinal (GI) bleeding. Methods. All cases in the GI registry with GI bleeding between 2003 and 2006 were reviewed. Cases with confirmed non-variceal aetiology were analysed. Rockall score > 5 was considered high risk for bleeding and primary outcomes studied were in-hospital mortality, recurrent bleeding and need for surgery. Results. The incidence of non-variceal upper GI bleeding was 2.2/100,000 person-years. Peptic ulcer bleeding was the most common aetiology (1.8/100,000 person-years). In-hospital mortality (3.6%), recurrent bleeding (9.6%) and need for surgery (4.0%) were uncommon in this population with a largely low risk score (85.2% with score ≤5). Elderly were at greater risk for bleeding (mean 68.5 years, P = 0.01) especially in the presence of duodenal ulcers (P = 0.04) despite gastric ulcers being more common. NSAIDs, aspirin and co-morbidities were the main risk factors. Conclusions. The absence of H. pylori infection may not reduce the risk of peptic ulcer bleeding in the presence of risk factors especially offending drugs in the elderly.

    Purpose: There are no simple guidelines on when to perform multidetector-row computed tomography (MDCT) for diagnosis of obscure acute gastrointestinal bleeding (AGIB). We used a risk scoring system to evaluate the diagnostic power of MDCT for patients with obscure AGIB. Materials and methods: Ninety-two patients with obscure AGIB who were referred for an MDCT scan after unsuccessful endoscopic treatment at presentation were studied. We recorded clinical data and calculated Blatchford score for each patient. Patients who required transfusion more than 500 mL of blood to maintain the vital signs were classified as high-risk patients. Two radiologists independently reviewed and categorized MDCT signs of obscure AGIB. Discordant findings were resolved by consensus. One-way ANOVA was used to compare clinical data between two groups; kappa statistics were used to estimate agreement on MDCT findings between radiologists. Results: Of the 92 patients, 62 (67.4%) were classified as high-risk patients. Blatchford scores of high-risk patients were significantly greater than those of low-risk patients. Sensitivity for MDCT diagnosing obscure AGIB was 81% in high-risk patients, as compared with 50% in the low-risk. When used in conjunction with selection of the cut-off value of 13 in Blatchford scoring system, the sensitivity and specificity of MDCT were 70.9% and 73.7%, respectively. Contrast extravasation was the most specific sign of AGIB (k = .87), recognition of which would have improved diagnostic accuracy. Conclusions: With the aid of Blatchford scoring system for evaluating the disease severity, MDCT can localize the bleeders of obscure AGIB more efficiently.

    Full Text Available BACKGROUND: Selective serotonin reuptake inhibitors (SSRIs have been associated with upper gastrointestinal (GI bleeding. Given their worldwide use, even small risks account for a large number of cases. This study has been conducted with carefully collected information to further investigate the relationship between SSRIs and upper GI bleeding. METHODS: We conducted a case-control study in hospitals in Spain and in Italy. Cases were patients aged ≥18 years with a primary diagnosis of acute upper GI bleeding diagnosed by endoscopy; three controls were matched by sex, age, date of admission (within 3 months and hospital among patients who were admitted for elective surgery for non-painful disorders. Exposures to SSRIs, other antidepressants and other drugs were defined as any use of these drugs in the 7 days before the day on which upper gastrointestinal bleeding started (index day. RESULTS: 581 cases of upper GI bleeding and 1358 controls were considered eligible for the study; no differences in age or sex distribution were observed between cases and controls after matching. Overall, 4.0% of the cases and 3.3% of controls used an SSRI antidepressant in the week before the index day. No significant risk of upper GI bleeding was encountered for SSRI antidepressants (adjusted odds ratio, 1.06, 95% CI, 0.57-1.96 or for whichever other grouping of antidepressants. CONCLUSIONS: The results of this case-control study showed no significant increase in upper GI bleeding with SSRIs and provide good evidence that the magnitude of any increase in risk is not greater than 2.

    BACKGROUND & AIMS: Two randomized controlled studies have evaluated the effect of recombinant Factor VIIa (rFVIIa) on variceal bleeding in cirrhosis without showing significant benefit. The aim of the present study was to perform a meta-analysis of the two trials on individual patient data...... vasoactive drug infusion and Child-Pugh score >8. RESULTS: 497 patients were eligible for the meta-analysis; 308 (62%) had active variceal bleeding at endoscopy (oozing or spurting) and 283 of these had a Child-Pugh score >8. Analysis on the composite endpoint in all patients with bleeding from oesophageal...... varices did not show any beneficial treatment effect. However, failure rate for the primary composite end-point was significantly lower in treated patients with active bleeding at endoscopy (17%) compared to placebo (26%, p=0.049). This difference was highly significant in patients with Child-Pugh score...

    Full Text Available To determine the outcome of severe dengue viral infection (DVI and the main dengue fatality risk factors.The medical records of patients aged <15 years admitted to Songklanagarind Hospital in southern Thailand during 1989-2011 were reviewed. Patients who had dengue hemorrhagic fever (DHF grades III-IV, organ failure (cardiovascular, respiratory, liver, renal or hematologic, impaired consciousness, or aspartate aminotransferase more than 1,000 units/L, were classified as having severe DVI. To determine the fatality risk factors of severe DVI, the classification trees were constructed based on manual recursive partitioning.Of the 238 children with severe DVI, 30 (12.6% died. Compared to the non-fatal DVI cases, the fatal cases had higher rates of DHF grade IV (96.7% vs 24.5%, repeated shock (93.3% vs 27.9%, acute respiratory failure (ARF (100% vs 6.7%, acute liver failure (ALF (96.6% vs 6.3%, acute kidney injury (AKI (79.3% vs 4.5%, and active bleeding requiring blood transfusion (93.3% vs 5.4%, all p<0.01. The combined risk factors of ARF and active bleeding considered together predicted fatal outcome with sensitivity, specificity, and negative and positive predictive values of 0.93 (0.78-0.99, 0.97 (0.93-0.99, 0.99 (0.97-1.00, and 0.82 (0.65-0.93, respectively. The likelihood ratios for a fatal outcome in the patients who had and did not have this risk combination were 32.4 (14.6-71.7 and 0.07 (0.02-0.26, respectively.Severe DVI patients who have ARF and active bleeding are at a high risk of death, while patients without these things together should survive.

    Purpose: To report a novel technique and preliminary clinical outcomes in managing lower gastrointestinal bleeding (LGIB). Materials and methods: Eighteen LGIB patients (11 men and 7 women, mean age: 66.2 years) were treated with artificially induced vasospasm therapy by semi-selective catheterization technique. Epinephrine bolus injection was used to initiate the vascular spasm, and followed by a small dose vasopressin infusion (3–5 units/h) for 3 h. The technical success, clinical success, recurrent bleeding and major complications of this study were evaluated and reported. Results: Sixteen bleeders were in the superior mesenteric artery and 2 in the inferior mesenteric artery. All patients achieved successful immediate hemostasis. Early recurrent bleeding (<30 days) was found in 4 patients with local and new-foci re-bleeding in 2 (11.1%) each. Repeated vasospasm therapy was given to 3 patients, with clinical success in 2. Technical success for the 21 bleeding episodes was 100%. Lesion-based and patient-based primary and overall clinical successes were achieved in 89.4% (17/19) and 77.7% (14/18), and 94.7% (18/19) and 88.8% (16/18), respectively. None of our patients had complications of bowel ischemia or other major procedure-related complications. The one year survival of our patients was 72.2 ± 10.6%. Conclusions: Pharmaco-induced vasospasm therapy seems to be a safe and effective method to treat LGIB from our small patient-cohort study. Further evaluation with large series study is warranted. Considering the advanced age and complex medical problems of these patients, this treatment may be considered as an alternative approach for interventional radiologists in management of LGIB.

    Fenger-Eriksen, C; Münster, A-M; Grove, E L

    2014-07-01

    New oral anticoagulants like the direct thrombin inhibitor, dabigatran (Pradaxa®), and factor Xa-inhibitors, rivaroxaban (Xarelto®) and apixaban (Eliquis®) are available for prophylaxis and treatment of thromboembolic disease. They are emerging alternatives to warfarin and provide equal or better clinical outcome together with reduced need for routine monitoring. Methods for measuring drug concentrations are available, although a correlation between plasma drug concentrations and the risk of bleeding has not been firmly established. Standard laboratory measures like prothrombin time and activated partial thromboplastin time are not sensitive enough to detect thrombin or factor Xa inhibition provided by new oral anticoagulants. Thus, these standard tests may only be used as a crude estimation of the actual anticoagulation status. Further challenges regarding patients receiving new oral anticoagulants who presents with major bleeding or need for emergency surgery pose a unique problem. No established agents are clinically available to reverse the anticoagulant effect, although preclinical data report prothrombin complex concentrate as more efficient than fresh frozen plasma or other prohaemostatic agents. This review summaries current knowledge on approved new oral anticoagulants and discusses clinical aspects of monitoring, with particular focus on the management of the bleeding patient.

    Judith Kooiman

    Full Text Available The HAS-BLED score enables a risk estimate of major bleeds in patients with atrial fibrillation on vitamin K-antagonists (VKA treatment, but has not been validated for patients with venous thromboembolism (VTE. We analyzed whether the HAS-BLED score accurately identifies patients at high risk of major bleeds during VKA treatment for acute VTE.Medical records of 537 patients with acute VTE (primary diagnosis pulmonary embolism in 223, deep vein thrombosis in 314 starting VKA treatment between 2006-2007 were searched for items on the HAS-BLED score and the occurrence of major bleeds during the first 180 days of follow-up. The hazard ratio (HR for the occurrence of major bleeds comparing non-high with high-risk patients as defined by a HAS-BLED score ≥ 3 points was calculated using Cox-regression analysis.Major bleeds occurred in 11/537 patients (2.0%, 5.2/100 person years, 95% CI 2.8-9.2. Cumulative incidences of major bleeds were 1.3% (95% CI 0.1-2.5 in the non-high (HAS-BLED < 3 and 9.6% (95%CI 2.2-17.0 in the high-risk group (HAS-BLED ≥ 3, (p <0.0001 by Log-Rank test, with a HR of 8.7 (95% CI 2.7-28.4. Of the items in the HAS-BLED score, abnormal renal function (HR 10.8, 95% CI 1.9-61.7 and a history of bleeding events (HR 10.4, 95% CI 2.5-42.5 were independent predictors of major bleeds during follow-up.Acute VTE patients with a HAS-BLED score ≥ 3 points are at increased risk of major bleeding. These results warrant for correction of the potentially reversible risk factors for major bleeding and careful International Normalized Ratio monitoring in acute VTE patients with a high HAS-BLED score.

    Lactic acidosis is common and most often associated with disturbed acid-base balance. Rarely, it can be a life-threatening medication side effect. Hence, determining the etiology of lactic acidosis early in patients is paramount in choosing the correct therapeutic intervention. Although lactic acidosis as an adverse drug reaction of linezolid is a well-recognized and documented clinical entity, the occurrence of such mimicking an acute intracranial bleed has not been reported to our knowledge. The following case is presented as an example of such an occurrence. A 67-year-old woman presented to the emergency department for lethargy, nausea and syncope. The head CT did not demonstrate any bleeding or mass effect, but lab results were significant for elevated lactic acid. The patient recently underwent left total hip replacement surgery, which was complicated by a methicillin-resistant Staphylococcus aureus (MRSA) infection. She received 6 weeks of oral linezolid therapy. And upon learning that key part of her history, the linezolid was discontinued. Her lactic acid rapidly normalized and she was discharged home. Several publications demonstrate that linezolid induces lactic acidosis by disrupting crucial mitochondrial functions. It is essential that clinicians are aware that linezolid can cause lactic acidosis. And, the important reminder is that adverse drug reactions can often mimic common diseases. If it is not recognized early, ominous clinical consequences may occur. In conclusion, linezolid should be suspected and included in the differential diagnosis if lactic acidosis exists with an uncommon clinical picture. PMID:27635182

    AIM: To determine the correlation of Adjusted Blood Requirement Index (ABRI) with the 7th day outcome in patients presenting with acute variceal bleeding.METHODS: All patients presenting with acute variceal hemorrhage (AVH) were included. Patients with previous band ligation, sclerotherapy, gastrointestinal or hepatic malignancies were excluded. Patients were managed as per standard protocol for AVH with terlipressin and band ligation. ABRI scores were calculated using the formula outcome of alive or expired up to the 7th day after treatment. The correlation between ABRI and mortality was estimated and a receiver operative characteristic (ROC) curve was plotted.RESULTS: A total of 113 patients (76 male; 37 female) were included. On assessment, 18 were in Child's Pugh Class A, 82 in Class B and 13 were in Class C. The median number of blood units transfused ± inter-quartile range was 3.0 ± 2.0. The median ± inter-quartile range for ABRI was 1.3 ± 1.1. The ROC curve of ABRI for expiry showed a significantly large area of 0.848 ( P < 0.0001; 95% CI: 0.75-0.95). A significant correlation of log transformation of ABRI with an outcome of mortality was present ( P < 0.0001). CONCLUSION: ABRI correlates strongly with mortality.

    PurposeRegional portal hypertension (RPH) is an uncommon clinical syndrome resulting from splenic vein stenosis/occlusion, which may cause gastrointestinal (GI) bleeding from the esophagogastric varices. The present study evaluated the safety and efficacy of transjugular endovascular recanalization of splenic vein in patients with GI bleeding secondary to RPH.MethodsFrom December 2008 to May 2011, 11 patients who were diagnosed with RPH complicated by GI bleeding and had undergone transjugular endovascular recanalization of splenic vein were reviewed retrospectively. Contrast-enhanced computed tomography revealed splenic vein stenosis in six cases and splenic vein occlusion in five. Etiology of RPH was chronic pancreatitis (n = 7), acute pancreatitis with pancreatic pseudocyst (n = 2), pancreatic injury (n = 1), and isolated pancreatic tuberculosis (n = 1).ResultsTechnical success was achieved in 8 of 11 patients via the transjugular approach, including six patients with splenic vein stenosis and two patients with splenic vein occlusion. Two patients underwent splenic vein venoplasty only, whereas four patients underwent bare stents deployment and two covered stents. Splenic vein pressure gradient (SPG) was reduced from 21.5 ± 7.3 to 2.9 ± 1.4 mmHg after the procedure (P < 0.01). For the remaining three patients who had technical failures, splenic artery embolization and subsequent splenectomy was performed. During a median follow-up time of 17.5 (range, 3–34) months, no recurrence of GI bleeding was observed.ConclusionsTransjugular endovascular recanalization of splenic vein is a safe and effective therapeutic option in patients with RPH complicated by GI bleeding and is not associated with an increased risk of procedure-related complications.

    Full Text Available Despite improvements in management and prevention of intracerebral hemorrhage (ICH, there has been little improvement in mortality over the last 30 years. Hematoma expansion, primarily during the first few hours is highly predictive of neurological deterioration, poor functional outcome and mortality. For each 10% increase in ICH size, there is a 5% increase in mortality and an additional 16% chance of poorer functional outcome. As such, both the identification and prevention of hematoma expansion are attractive therapeutic targets in ICH. Previous studies suggest that contrast extravasation seen on CT Angiography (CTA, MRI, and digital subtraction angiography correlates with hematoma growth, indicating ongoing bleeding. Contrast extravasation on the arterial phase of a CTA has been coined the CTA Spot Sign. These easily identifiable foci of contrast enhancement have been identified as independent predictors of hematoma growth, mortality and clinical outcome in primary ICH. The Spot Sign score, developed to stratify risk of hematoma expansion, has shown high inter-observer agreement. Post-contrast leakage or delayed CTA Spot Sign, on post contrast CT following CTA or delayed CTA respectively are seen in an additional ~8% of patients and explain apparently false negative observations on early CTA imaging in patients subsequently undergoing hematoma expansion. CT perfusion provides an opportunity to acquire dynamic imaging and has been shown to quantify rates of contrast extravasation. Intravenous recombinant factor VIIa(rFVIIa within 4 hours of ICH onset has been shown to significantly reduce hematoma growth. However, clinical efficacy has yet to be proven. There is compelling evidence that cerebral amyloid angiopathy (CAA may precede the radiographic evidence of vascular disease and as such contribute to microbleeding. The interplay between microbleeding, CAA,CTA Spot Sign and genetic composition (ApoE genotype may be crucial in developing a

    Acute gastrointestinal bleeding(AGIB) is a prevalent condition with significant influence on healthcare costs. Endoscopy is essential for the management of AGIB with a pivotal role in diagnosis, risk stratification and management. Recently, hemostatic powders have been added to our endoscopic armamentarium to treat gastrointestinal(GI) bleeding. These substances are intended to control active bleeding by delivering a powdered product over the bleeding site that forms a solid matrix with a tamponade function. Local activation of platelet aggregation and coagulation cascade may be also boosted. There are currently three powders commercially available: hemostatic agent TC-325(Hemospray), EndoClotTM polysaccharide hemostatic system, and Ankaferd Bloodstopper. Although the available evidence is based on short series of cases and there is no randomized controlled trial yet, these powders seem to be effective in controlling GI bleeding from a variety of origins with a very favorable side effects profile. They can be used either as a primary therapy or a secondline treatment, and they seem to be especially indi-cated in cases of cancer-related bleeding and lesions with difficult access. In this review, we will comment on the mechanism of action, efficacy, safety and technical challenges of the use of powders in several clinical scenarios and we will try to define the main current indications of use and propose new lines of research in this area.

    To determine whether treatment outcome is associated with visualization of contrast extravasation in patients with acute massive gastrointestinal bleeding after endoscopic failure. From January 2007 to December 2009, patients that experienced a first attack of acute gastrointestinal bleeding after failure of initial endoscopy were referred to our interventional department for intra-arterial treatment. We enrolled 79 patients and divided them into two groups: positive and negative extravasation. For positive extravasation, patients were treated by coil embolization; and in negative extravasation, patients were treated with intra-arterial vasopressin infusion. The two groups were compared for clinical parameters, hemodynamics, laboratory findings, endoscopic characteristics, and mortality rates. Forty-eight patients had detectable contrast extravasation (positive extravasation), while 31 patients did not (negative extravasation). Fifty-six patients survived from this bleeding episode (overall clinical success rate, 71%). An elevation of hemoglobin level was observed in the both two groups; significantly greater in the positive extravasation group compared to the negative extravasation group. Although these patients were all at high risk of dying, the 90-day mortality rate was significantly lower in the positive extravasation than in the negative extravasation (20% versus 42%, p < 0.05). A multivariate analysis suggested that successful hemo stasis (odds ratio [OR] = 28.66) is the most important predictor affecting the mortality in the two groups of patients. Visualization of contrast extravasation on angiography usually can target the bleeding artery directly, resulting in a higher success rate to control of hemorrhage.

    AIM: To assess the frequency and the risk factors of stress-induced gastrointestinal (GI) bleeding in children admitted to a pediatric intensive care unit (PICU).METHODS: The medical records of children aged between 1 month and 15 years admitted to the PICU between January 2002 and December 2002 were reviewed.Demographic data, indications for PICU admission, principle diagnosis, and basic laboratory investigations were recorded. Previously described factors for stress ulcer bleeding (mechanical ventilation, sepsis, acute respiratory distress syndrome, renal insufficiency, coagulopathy,thrombocytopenia, and intracranial pathology) were used as independent variables in a multivariate analysis.RESULTS: One hundred and seventy of two hundred and five medical records were eligible for review. The most common indication for PICU admission was respiratory failure (48.8%). Twenty-five children received stress ulcer bleeding prophylaxis with ranitidine. The incidence of stress ulcer bleeding was 43.5%, in which 5.3% were clinically significant bleeding. Only mechanical ventilation and thrombocytopenia were significantly associated with stress ulcer bleeding using the univariate analysis.The odds ratio and 95% confidence intervals were 5.13(1.86-14.12) and 2.26 (1.07-4.74), respectively. However, the logistic regression analysis showed that mechanicai ventilation was the only significant risk factor with the odds ratio of 14.1.CONCLUSION: The incidence of gastrointestinal bleeding was high in critically ill children. Mechanical ventilation was an important risk factor for gastrointestinal bleeding.

Blood losses in this patient population can be quite severe at times and it is important to differentiate anemia of chronic diseases from anemia due to GI bleeding. We review the literature on common causes of lower gastrointestinal bleeding (LGI in chronic kidney disease (CKD and end-stage renal disease (ESRD patients. We suggest an approach to diagnosis and management of this problem.

    The closed experimental animal model system was used to compare the detectable gastrointestinal (GI) bleeding rates of {sup 99m}Tc-DTPA, {sup 99m}Tc-RBCs and {sup 99m}Tc tin colloid in sheep. The three radiopharmaceuticals were used to detect the upper GI bleeding sites at rates of 0.57 and 0.25 ml/min. At the lower bleeding rate of 0.1 ml/min, both {sup 99m}Tc-DTPA and {sup 99m}Tc-RBCs were successful in detecting the bleeding site. At the lowest rate of 0.07 ml/min only {sup 99m}Tc-DTPA was successful in detecting the bleeding site. The results indicate that {sup 99m}Tc-DTPA is the most useful {sup 99m}Tc radiopharmaceutical for detecting the upper GI bleeding site at the slowest bleeding rate studied. (orig.).

  11. Trouble with bleeding: risk factors for acute hepatitis C among HIV-positive gay men from Germany--a case-control study.

    Axel J Schmidt

    Full Text Available OBJECTIVES: To identify risk factors for hepatitis C among HIV-positive men who have sex with men (MSM, focusing on potential sexual, nosocomial, and other non-sexual determinants. BACKGROUND: Outbreaks of hepatitis C virus (HCV infections among HIV-positive MSM have been reported by clinicians in post-industrialized countries since 2000. The sexual acquisition of HCV by gay men who are HIV positive is not, however, fully understood. METHODS: Between 2006 and 2008, a case-control study was embedded into a behavioural survey of MSM in Germany. Cases were HIV-positive and acutely HCV-co-infected, with no history of injection drug use. HIV-positive MSM without known HCV infection, matched for age group, served as controls. The HCV-serostatus of controls was assessed by serological testing of dried blood specimens. Univariable and multivariable regression analyses were used to identify factors independently associated with HCV-co-infection. RESULTS: 34 cases and 67 controls were included. Sex-associated rectal bleeding, receptive fisting and snorting cocaine/amphetamines, combined with group sex, were independently associated with case status. Among cases, surgical interventions overlapped with sex-associated rectal bleeding. CONCLUSIONS: Sexual practices leading to rectal bleeding, and snorting drugs in settings of increased HCV-prevalence are risk factors for acute hepatitis C. We suggest that sharing snorting equipment as well as sharing sexual partners might be modes of sexual transmission. Condoms and gloves may not provide adequate protection if they are contaminated with blood. Public health interventions for HIV-positive gay men should address the role of blood in sexual risk behaviour. Further research is needed into the interplay of proctosurgery and sex-associated rectal bleeding.

  12. Iatrogenic Complications in Five Patients with Upper Gastrointestinal Bleeding due to Ambient Air: Case Series and Literature Review

    Christine N. Manser

    2012-04-01

    Full Text Available Despite the increasing use of carbon dioxide for endoscopies during the last years, ambient air is still used. The amount of air depends on several factors such as examination time, presumable diameter of the endoscope channel and of course active use of air by the operator. Although endoscopic complications due to ambient air in the gastrointestinal (GI tract are a rare observation and mostly described in the colon, we report five cases in the upper GI tract due to insufflating large amounts of air through the endoscopes. All 5 patients needed an emergency upper endoscopy for acute presumed upper GI bleeding. In two cases both esophageal variceal bleeding and ulcer bleeding were detected; the fifth case presented with a bleeding due to gastric cancer. Due to insufflation of inadequate amounts of air through the endoscope channel, all patients deteriorated in circulation and ventilation. Two rumenocenteses and consecutively three laparotomies had to be performed in three patients. In the other two, gastroscopies had to be stopped for an emergency computed tomography. All critical incidents were believed to be a consequence of a long-lasting examination with use of too much air. Therefore in emergency situations, endoscopies should be performed with either submersion, low air flow pumps or even better by the use of carbon dioxide.

    Capsule endoscopy (CE) is a safe, non invasive diagnostic modality for the evaluation of small bowel lesions. Obscure gastrointestinal bleeding (OGIB) is one of the most important indications of capsule endoscopy.Capsule endoscopy has a very high diagnostic yield especially if the bleeding is ongoing. This technique appears to be superior to other techniques for the detection of suspected lesions and the source of bleeding. Capsule endoscopy has been shown to change the outcome in patients with obscure gastrointestinal (GI)bleed.

    AIM:To investigate the contribution of anti-platelet therapy and derangements of pre-operative classical coagulation and thromboelastometry parameters to major bleeding post-coronary artery bypass grafting(CABG).METHODS:Two groups of CABG patients were studied:Group A,treated with aspirin alone(n=50),and Group B treated with aspirin and clopidogrel(n=50).Both had similar preoperative,clinical,biologic characteristics and operative management.Classic coagulation parameters and rotational thromboelastometry(ROTEM)profiles were determined preoperatively for both groups and the same heparin treatment was administered.ROTEM profiles(INTEM and EXTEM assays)were analyzed,both for traditional parameters,and thrombin generation potential,expressed by area-under-curve(AUC).RESULTS:There was no significant difference betweenrates of major bleeding between patients treated with aspirin alone,compared with those treated with aspirin and clopidogrel(12%vs 16%,P=0.77).In the 14 cases of major bleeding,pre-operative classic coagulation and traditional ROTEM parameters were comparable.Conversely we observed that the AUC in the EXTEM test was significantly lower in bleeders(5030±1115 Ohm*min)than non-bleeders(6568±548Ohm*min)(P<0.0001).CONCLUSION:We observed that patients with a low AUC value were at a significantly higher risk of bleeding compared to patients with higher AUC,regardless of antiplatelet treatment.This suggests that thrombin generation potential,irrespective of the degree of platelet inhibition,correlates with surgical bleeding.

    Objectives This study sought to report additional safety results from the ROCKET AF (Rivaroxaban Once-daily oral Direct Factor Xa Inhibition Compared with Vitamin K Antagonism for Prevention of Stroke and Embolism Trial in Atrial Fibrillation). Background The ROCKET AF trial demonstrated similar risks of stroke/systemic embolism and major/nonmajor clinically relevant bleeding (principal safety endpoint) with rivaroxaban and warfarin. Methods The risk of the principal safety and component bleeding endpoints with rivaroxaban versus warfarin were compared, and factors associated with major bleeding were examined in a multivariable model. Results The principal safety endpoint was similar in the rivaroxaban and warfarin groups (14.9 vs. 14.5 events/100 patient-years; hazard ratio: 1.03; 95% confidence interval: 0.96 to 1.11). Major bleeding risk increased with age, but there were no differences between treatments in each age category (<65, 65 to 74, ≥75 years; pinteraction = 0.59). Compared with those without (n = 13,455), patients with a major bleed (n = 781) were more likely to be older, current/prior smokers, have prior gastrointestinal (GI) bleeding, mild anemia, and a lower calculated creatinine clearance and less likely to be female or have a prior stroke/transient ischemic attack. Increasing age, baseline diastolic blood pressure (DBP) ≥90 mm Hg, history of chronic obstructive pulmonary disease or GI bleeding, prior acetylsalicylic acid use, and anemia were independently associated with major bleeding risk; female sex and DBP <90 mm Hg were associated with a decreased risk. Conclusions Rivaroxaban and warfarin had similar risk for major/nonmajor clinically relevant bleeding. Age, sex, DBP, prior GI bleeding, prior acetylsalicylic acid use, and anemia were associated with the risk of major bleeding.

    2010-01-01

    Background Emergency treatment of bleeding esophageal varices in cirrhosis is of singular importance because of the high mortality rate. Emergency portacaval shunt is rarely used today because of the belief, unsubstantiated by long-term randomized trials, that it causes frequent portal-systemic encephalopathy and liver failure. Consequently, portacaval shunt has been relegated solely to salvage therapy when endoscopic and pharmacologic therapies have failed. Question: Is the regimen of endoscopic sclerotherapy with rescue portacaval shunt for failure to control bleeding varices superior to emergency portacaval shunt? A unique opportunity to answer this question was provided by a randomized controlled trial of endoscopic sclerotherapy versus emergency portacaval shunt conducted from 1988 to 2005. Methods Unselected consecutive cirrhotic patients with acute bleeding esophageal varices were randomized to endoscopic sclerotherapy (n = 106) or emergency portacaval shunt (n = 105). Diagnostic workup was completed and treatment was initiated within 8 h. Failure of endoscopic sclerotherapy was defined by strict criteria and treated by rescue portacaval shunt (n = 50) whenever possible. Ninety-six percent of patients had more than 10 years of follow-up or until death. Results Comparison of emergency portacaval shunt and endoscopic sclerotherapy followed by rescue portacaval shunt showed the following differences in measurements of outcomes: (1) survival after 5 years (72% versus 22%), 10 years (46% versus 16%), and 15 years (46% versus 0%); (2) median post-shunt survival (6.18 versus 1.99 years); (3) mean requirements of packed red blood cell units (17.85 versus 27.80); (4) incidence of recurrent portal-systemic encephalopathy (15% versus 43%); (5) 5-year change in Child’s class showing improvement (59% versus 19%) or worsening (8% versus 44%); (6) mean quality of life points in which lower is better (13.89 versus 27.89); and (7) mean cost of care per

    Full Text Available BACKGROUND: The efficacy of clopidogrel is inconclusive in the chronic kidney disease (CKD population with acute coronary syndrome (ACS. Furthermore, CKD patients are prone to bleeding with antiplatelet therapy. We investigated the efficacy and safety of clopidogrel in patients with ACS and CKD. METHODS: In a Taiwan national-wide registry, 2819 ACS patients were enrolled. CKD is defined as an estimated glomerular filtration rate of less than 60 ml/min per 1.73 m(2. The primary endpoints are the combined outcomes of death, non-fatal myocardial infarction and stroke at 12 months. RESULTS: Overall 949 (33.7% patients had CKD and 2660 (94.36% patients received clopidogrel treatment. CKD is associated with increased risk of the primary endpoint at 12 months (HR 2.39, 95% CI 1.82 to 3.15, p<0.01. Clopidogrel use is associated with reduced risk of the primary endpoint at 12 months (HR 0.42, 95% CI: 0.29-0.60, p<0.01. Cox regression analysis showed that clopidogrel reduced death and primary endpoints for CKD population (HR 0.35, 95% CI: 0.21-0.61 and HR 0.48, 95% CI: 0.30-0.77, respectively, both p<0.01. Patients with clopidogrel(-/CKD(-, clopidogrel(+/CKD(+ and clopidogrel(-/CKD(+ have 2.4, 3.0 and 10.4 fold risk to have primary endpoints compared with those receiving clopidogrel treatment without CKD (all p<0.01. Clopidogrel treatment was not associated with increased in-hospital Thrombolysis In Myocardial Infarction (TIMI bleeding in CKD population. CONCLUSION: Clopidogrel could decrease mortality and improve cardiovascular outcomes without increasing risk of bleeding in ACS patients with CKD.

    Full Text Available Background. Recent findings suggest that patients admitted on the weekend with peptic ulcer bleeding might be at increased risk of adverse outcomes. However, other reports found that there was no “holiday effect.” The purpose of this study was to determine if these findings hold true for a real-life Taiwanese medical gastroenterology practice. Materials and Methods. We reviewed the medical files of hospital admissions for patients with peptic ulcer bleeding who received initial endoscopic hemostasis between January 2009 and March 2011. A total of 744 patients were enrolled (nonholiday group, n=615; holiday group, n=129 after applying strict exclusion criteria. Holidays were defined as weekends and national holidays in Taiwan. Results. Our results showed that there was no significant difference in baseline characteristics between the two groups. We also observed that, compared to the nonholiday group, patients in the holiday group received earlier endoscopy treatment (12.20 hours versus 16.68 hours, P=0.005, needed less transfused blood (4.8 units versus 6.6 units, P=0.02, shifted from intravenous to oral proton-pump inhibitors (PPIs more quickly (5.3 days versus 6.9 days, P=0.05, and had shorter hospital stays (13.05 days versus 17.36 days, P=0.005. In the holiday and nonholiday groups, the rebleeding rates were 17.8% and 23.41% (P=0.167, the mortality rates were 11.63% versus 13.66% (P=0.537, and surgery was required in 2.11% versus 4.66% (P=0.093, respectively. Conclusions. Patients who presented with peptic ulcer bleeding on holidays did not experience delayed endoscopy or increased adverse outcomes. In fact, patients who received endoscopic hemostasis on the holiday had shorter waiting times, needed less transfused blood, switched to oral PPIs quicker, and experienced shorter hospital stays.

    Background Bleeding esophageal varices (BEV) in cirrhosis has been considered an indication for liver transplantation (LT). This issue was examined in a randomized controlled trial (RCT) of unselected, consecutive patients with advanced cirrhosis and BEV that compared endoscopic sclerotherapy (EST) (n=106) to emergency direct portacaval shunt (EPCS) (n=105). Methods Diagnostic workup and treatment were initiated within 8 hours. Patients were evaluated for LT on admission and repeatedly thereafter. 96% underwent over 10 years of regular follow-up. The analysis was supplemented by 1300 unrandomized cirrhotic patients who previously underwent portacaval shunt (PCS) with 100% follow-up. Results In the RCT, long-term bleeding control was 100% following EPCS, only 20% following EST. 3, 5, 10, and 15-year survival rates were 75%, 73%, 46%, and 46% following EPCS, compared to 44%, 21%, 9%, and 9% following EST (p<0.001). Only 13 RCT patients (6%) were ultimately referred for LT mainly because of progressive liver failure; only 7 (3%) were approved for LT and only 4 (2%) underwent LT. 1- and 5-year LT survival rates were 0.68% and 0, compared to 81% and 73% after EPCS. In the 1300 unrandomized PCS patients. 50 (3.8%) were referred and 19 (1.5%) underwent LT. Five-year survival rate was 53% compared to 72% for all 1300 patients. Conclusions If bleeding is permanently controlled, as occurred invariably following EPCS, cirrhotic patients with BEV seldom require LT. PCS is effective first-line and long-term treatment. Should LT be required in patients with PCS, although technically more demanding, numerous studies have shown that PCS does not increase mortality or complications. EST is not effective emergency or long-term therapy. PMID:21168637

    Aim: To evaluate the usefulness of computed tomography (CT) enteroclysis in patients with obscure gastrointestinal (GI) bleeding. Materials and methods: In a prospective study, CT enteroclysis was performed in 21 patients (median age 50 years; range 13-71 years) with obscure GI bleeding in which the source of the bleeding could not be detected despite the patient having undergone both upper GI endoscopic and colonoscopic examinations. The entire abdomen and pelvis was examined in the arterial and venous phases using multisection CT after distending the small intestine with 2 l of 0.5% methylcellulose as a neutral enteral contrast medium and the administration of 150 ml intravenous contrast medium. Results: Adequate distension of the small intestine was achieved in 20 of the 21 (95.2%) patients. Potential causes of GI bleeding were identified in 10 of the 21 (47.6%) patients using CT enteroclysis. The cause of the bleeding could be detected nine of 14 (64.3%) patients with overt, obscure GI bleeding. However, for patients with occult, obscure GI bleeding, the cause of the bleeding was identified in only one of the seven (14.3%) patients. The lesions identified by CT enteroclysis included small bowel tumours (n = 2), small bowel intussusceptions (n = 2), intestinal tuberculosis (n = 2), and vascular lesions (n = 3). All vascular lesions were seen equally well in both the arterial and venous phases. Conclusions: The success rate in detection of the cause of bleeding using CT enteroclysis was 47.6% in patients with obscure GI bleeding. The diagnostic yield was higher in patients with overt, obscure GI bleeding than in those with occult obscure GI bleeding.

    Introduction. There is limited data evaluating physician transfusion practices in patients with acute upper gastrointestinal bleeding (UGIB). Methods. A web-based survey was sent to 500 gastroenterologists and hepatologists across Canada. The survey included clinical vignettes where physicians were asked to choose transfusion thresholds. Results. The response rate was 41% (N = 203). The reported hemoglobin (Hgb) transfusion trigger differed by up to 50 g/L. Transfusions were more liberal in hemodynamically unstable patients compared to stable patients (mean Hgb of 86.7 g/L versus 71.0 g/L; p iron to patients with UGIB who are anemic upon discharge. Conclusions. The transfusion practices of gastroenterologists in the management of UGIB vary widely and more high-quality evidence is needed to help assess the efficacy and safety of selected transfusion thresholds in varying patients presenting with UGIB.

    Percutaneous transluminal coronary intervention and antithrombotic therapy have resulted in significant improvement in reducing ischemic events in acute coronary syndrome, while leading to an increase in the risk of bleeding. There has been an increasing amount of data demonstrating that bleeding has a strong association with subsequent adverse outcomes. Therefore, it is imperative to optimize patient outcomes by performing bleeding risk assessment and stratification, adopting pharmacological and nonphannacological strategies to minimize bleeding while maximizing treatment efficacy. This review focuses on the classifications, epidemiology, adverse outcomes, and management of bleeding in patients with acute coronary syndrome.%经皮冠状动脉介入治疗与抗栓药物在显著降低急性冠状动脉综合征患者缺血事件的同时,也相应增加了出血风险.出血发生率增高与患者不良临床预后强烈相关.全面评估患者出血风险进行危险分层,谨慎平衡缺血与出血风险制定治疗策略,预防控制出血并发症,在临床实践中非常重要.现就急性冠状动脉综合征出血分级标准、出血发生率、预后及预防控制做一综述.

    Upper gastrointestinal (GI) bleeding is a serious complication that sometimes occurs after percutaneous radiologic gastrostomy (PRG). We evaluated the incidence of bleeding complications after a PRG and its management including transcatheter arterial embolization (TAE). We retrospectively reviewed 574 patients who underwent PRG in our institution between 2000 and 2010. Eight patients (1.4%) had symptoms or signs of upper GI bleeding after PRG. The initial presentation was hematemesis (n = 3), melena (n = 2), hematochezia (n = 2) and bloody drainage through the gastrostomy tube (n = 1). The time interval between PRG placement and detection of bleeding ranged from immediately after to 3 days later (mean: 28 hours). The mean decrease in hemoglobin concentration was 3.69 g/dL (range, 0.9 to 6.8 g/dL). In three patients, bleeding was controlled by transfusion (n = 2) or compression of the gastrostomy site (n = 1). The remaining five patients underwent an angiography because bleeding could not be controlled by transfusion only. In one patient, the bleeding focus was not evident on angiography or endoscopy, and wedge resection including the tube insertion site was performed for hemostasis. The other four patients underwent prophylactic (n = 1) or therapeutic (n = 3) TAEs. In three patients, successful hemostasis was achieved by TAE, whereas the remaining one patient underwent exploration due to persistent bleeding despite TAE. We observed an incidence of upper GI bleeding complicating the PRG of 1.4%. TAE following conservative management appears to be safe and effective for hemostasis.

    Background In obscure gastrointestinal (GI) bleeding, it is often difficult to detect the bleeding sites located in the small bowel with conventional radiological, scintigraphic or angiographic techniques. Push enteroscopy and capsule endoscopy are currently considered to be the most effective diagnostic procedures. The aim of this study was to compare the detection rates between capsule endoscopy and push enteroscopy. Methods From May 2002 through January 2003, we prospectively examined by capsule endoscopy 39 patients with suspected small bowel diseases, in particular GI bleeding of unknown origin in Renji Hospital. Among them, 32 complained of obscure recurrent GI bleeding. Between January 1993 and October 1996, we used push enteroscopy on 36 patients who suffered from unexplained GI bleeding. All patients had prior normal results on gastroscopy, colonoscopy, small bowel barium radiography, scintigraphy and/or angiography. Results M2A capsule endoscopy disclosed abnormal small bowel findings in 26 (82%) out of 32 patients. Twenty-one of them had significant pathological findings explaining their clinical disorders. Diagnostic yield was therefore 66% (21 of 32 patients). Definite bleeding sites diagnosed by capsule endoscopy in 21 patients included angiodysplasia (8), inflammatory small-bowel (5), small-bowel polyps (4), gastrointestinal stromal tumour (2), carcinoid tumour and lipoma (1), and hemorrhagic gastritis (1). Push enteroscopy detected the definite sources of bleeding in 9 (25%) of the 36 patients. Patients with definite bleeding sources included angiodysplasias (2), leiomyosarcoma (2), leiomyoma (1), lymphoma (1), Crohn's disease (1), small-bowel polyps (1) and adenocarcinoma of ampulla (1). Suspected bleeding sources were shown by push enteroscopy in two additional patients (6%), and in other five patients (16%) by capsule endoscopy.Conclusions The present study of patients with obscure GI bleeding showed that capsule endoscopy significantly superior

    Gastrointestinal bleeding is a common problem encountered in the emergency department and in the primary care setting. Acute or overt gastrointestinal bleeding is visible in the form of hematemesis, melena or hematochezia. Chronic or occult gastrointestinal bleeding is notapparent to the patient and usually presents as positive fecal occult blood or iron deficiency anemia. Obscure gastrointestinal bleeding is recurrent bleeding when the source remains unidentified after upper endoscopy and colonoscopic evaluation and is usually from the small intestine. Accurate clinical diagnosis is crucial and guides definitive investigations and interventions. This review summarizes the overall diagnostic approach to gastrointestinal bleeding and provides a practical guide for clinicians.

    Purpose: The purpose of our retrospective study was to determine the feasibility and efficacy of the endovascular embolization of peripheral acute arterial hemorrhage using Onyx. Materials and Methods: Between October 2003 and February 2007, 14 patients with acute arterial bleeding underwent percutaneous arterial embolization using Onyx. Bleeding was caused by iatrogenic vessel injury (6 patients), malignancy/inflammation (5 patients) and trauma (3 patients). Hematomas were located in the pelvis (5 patients), followed by liver (3 patients), retroperitoneal space (2 patients), thorax (2 patients), pancreas (1 patient), and thigh (1 patient). The number of embolized arteries, the volume and viscosity of embolic agent (Onyx), the number of additionally used coils, the embolization time, and the technical and clinical outcome were documented. Procedure-related complications, recurrent bleeding during hospital stay and outcome were recorded. Results: In 14 patients selective endovascular embolization of 15 arteries was performed. The average volume of injected Onyx was 1.3 {+-} 0.8 ml. In 6 cases (42.9%) Onyx was used in conjunction with coils. The average time between the correct placement of microcatheter and complete embolization was 24.9 {+-} 12.6 minutes. In 13 of 14 patients (92.8%), embolization was technically successful. In one case, procedure-related complications occurred and embolization was performed in a second session a day later. After technically successful embolization, no recurrent bleeding occurred during hospitalization. Out of 14 patients, six (42.9%) died 1 - 38 days after technically successful embolization due to multiple organ failure (2 patients), hypoxic brain injury (2 patients), septic shock (1 patient) or malignancy-associated death (1 patient).

    The present study aimed to identify novel predictors of upper gastrointestinal (GI) bleeding by assessing change ratios of blood test variables. Records of 1,023 patients (431 men and 592 women) who underwent endoscopy between October 2014 and September 2015 at the National Hospital Organization Shimoshizu Hospital (Yotsukaido, Japan) were retrospectively analyzed. Patients whose blood test variables for the time-point of endoscopy and three months previously were available were enrolled and subsequently categorized into a group with and another one without upper GI bleeding (n=32 and 84, respectively), and the respective change ratios were calculated for each group. One-way analysis of variance revealed that in patients with upper GI bleeding, change ratios of white blood cell count and alkaline phosphatase were significantly higher than those in patients without, while change ratios of hemoglobin (Hb), total protein and albumin were significantly reduced. Logistic regression analysis demonstrated that the change ratio of Hb was significantly correlated with upper GI bleeding. Receiver-operator characteristic analysis revealed that an 18.7% reduction of Hb was the threshold value for the prediction of upper GI bleeding. In conclusion, the present study revealed that a ≥18.7% reduction in Hb over three months has predictive value for upper GI bleeding.

  2. Radionuclide detection of lower gastrointestinal bleeding sites

    International Nuclear Information System (INIS)

    A retrospective review of two years' experience with radionuclide screening to detect lower gastrointestinal bleeding sites was conducted at New York's Montefiore Medical Center. Of 82 studies performed in 63 patients, 13 identified active bleeding sites. Only three of eight angiograms obtained in these 13 patients were positive. Thirteen contrast angiograms were performed in the group of 50 patients with negative radionuclide studies of which ten were negative and one was equivocal. The results of this study suggest that the Tc-99m sulfur colloid study for active lower gastrointestinal (GI) bleeding is an effective screening procedure. Positive studies help determine which vessel to catheterize selectively if an angiogram is to be performed. If vascular ectasis is still suspected following a negative radionuclide study, contrast angiography can be more efficaciously performed on a nonemergent basis

  3. Large Duodenal Gastrointestinal Stromal Tumor Presenting with Acute Bleeding Managed by a Whipple Resection. A Review of Surgical Options and the Prognostic Indicators of Outcome

    2011-03-01

    Full Text Available Context Duodenal gastrointestinal stromal tumors (GISTs are uncommon and constitute a relatively small subset of GISTs which presents a unique dilemma having various surgical options. A case of a large ulcerating duodenal GIST arising from the second and third parts of the duodenum and involving the pancreas which was managed by a Whipple resection is presented. The literature is also reviewed to present the current status on surgical options, outcome, prognostic indicators and the role of imatinib mesylate in its management. Case report A 58-year-old patient presented with acute gastrointestinal bleeding which was diagnosed to be due to a duodenal GIST following CT scan and endoscopic biopsy. The mass which measured about 10x9 cm originated from the 2nd part and extended into the 3rd part of the duodenum. He underwent a Whipple resection, and histopathology confirmed a duodenal GIST having a greater than 10 mitotic count per fifty high power field and areas of necrosis. Postoperatively, he received imatinib mesylate 400 mg bid; however, 4 months later, he presented with multiple disseminated peritoneal metastases and succumbed to the disease 2 months later. Conclusion GISTs of the duodenum which are small in size and do not involve the papilla of Vater are better resolved using a limited resection of the duodenum since the outcome in terms of operative risk or disease recurrence is not influenced in these cases. However, large tumors with more extensive involvement would require a pancreaticoduodenectomy to achieve adequate tumor clearance. Even though duodenal GISTs have a relatively better prognosis as compared to GISTs at other sites, their aggressiveness ranges from small indolent tumors to aggressive sarcomas. Following tumor resection, a recurrence rate of about 40% has been reported. A more favorable prognosis in duodenal GISTs is attributed to a lower prevalence of P53 loss, the duodenal location of the tumor, a smaller size of the

    Full Text Available Background: Peptic ulcers are among the most common causes of upper gastrointestinal (GI bleeding in children. The standard care for GI bleeding is endoscopy for diagnostic and therapeutic purposes. We aimed to assess the effect of topical tranexamic acid (TXA via endoscopic procedures in children with GI bleeding caused by bleeding ulcers. Procedure: In this randomised controlled trial, 120 children were evaluated by diagnostic procedures for GI bleeding, of which 63 (30 girls, 33 boys aged 1-month to 15 years were recruited. The patients were randomly divided into case and control groups. In the case group, TXA was administered directly under endoscopic therapy. In the control group, epinephrine (1/10,000 was submucosally injected to the four quadrants of ulcer margins as the routine endoscopic therapy. In both groups, the patients received supportive medical therapy with intravenous fluids and proton pump inhibitor drugs. Results: The mean ± standard deviation age of the children was 5 ± 2.03 years. Rebleeding occurred in 15 (11.4% and 21 (9.8% patients in the case and control groups, respectively (P = 0.50. The frequency of blood transfusion episodes (P = 0.06 and duration of hospital stay (P = 0.07 were not statistically different between the groups. Conclusion: Using topical TXA via endoscopic procedures may be effective in cases of GI bleedings caused by active bleeding ulcers. In order to establish this therapeutic effect, a large number of clinical studies are needed.

    Assessment of the bleeding risk of antithrombotic agents is usually performed in healthy animals with some form of vascular injury to peripheral organs to induce bleeding. However, bleeding observed in patients with currently marketed antithrombotic drugs is typically spontaneous in nature such as intracranial haemorrhage (ICH) and gastrointestinal (GI) bleeding, which happens most frequently on top of preexisting pathologies such as GI ulcerations and polyps. Apc(min/+) mice are reported to develop multiple adenomas through the entire intestinal tract and display progressive anaemia.In this study, we evaluated the potential utility of Apc(min/+) mice as a model for assessing spontaneous GI bleeding with antithrombotic agents. Apc(min/+) mice exhibited progressive blood loss starting at the age of nine weeks. Despite the increase in bleeding, Apc(min/+) mice were in a hypercoagulable state and displayed an age-dependent increase in thrombin generation and circulating fibrinogen as well as a significant decrease in clotting times. We evaluated the effect of warfarin, dabigatran etexilate, apixaban and clopidogrel in this model by administering them in diet or in the drinking water to mice for 1-4 weeks. All of these marketed drugs significantly increased GI bleeding in Apc(min/+) mice, but not in wild-type mice. Although different exposure profiles of these antithrombotic agents make it challenging to compare the bleeding risk of compounds, our results indicate that the Apc(min/+) mouse may be a sensitive preclinical model for assessing the spontaneous GI bleeding risk of novel antithrombotic agents.

    Primary splenic angiosarcoma is a very rare,aggressive neoplasm with a high metastatic rate and dismal prognosis. This neoplasm usually presents with abdominal pain, splenomegaly, anemia, and thrombocytopenia. Splenic angiosarcoma with bleeding gastrointestinal metastases is extremely rare. The literature contains only two case reports. This study reported a 44-year-old male patient with splenic angiosarcoma with sustained repeated gastrointestinal bleeding due to small bowel metastases. Salvage surgery was performed by splenectomy and resection of the metastatic small bowel tumors. The post-operative course was uneventful; the patient survived with the disease and had no GI bleeding, 7 mo after surgery.

  7. Accuracy of rockall score for in hospital re bleeding among cirrhotic patients with variceal bleed

    International Nuclear Information System (INIS)

    To assess the diagnostic accuracy of Roc kall scoring system for predicting in-hospital re-ble- eding in cirrhotic patients presenting with variceal bleed. Material and Methods: This descriptive case series study was conducted at Department of Medicine Combined Military Hospital Lahore from December 2013 to May 2014. We included patients with liver cirrhosis who presented with upper GI bleeding and showed varices as the cause of bleeding on endoscopy. Clinical and endoscopic features were noted to calculate Rockall score. Patients with score < 2 and > 8 were included. After treating with appropriate pharmacological and endoscopic therapy, patients were followed for re-bleeding for 10 days. Diagnostic accuracy was assessed by calculating sensitivity, specificity, positive and negative predictive values using 2 x 2 tables. Results: In the study, 175 patients were included. Mean age was 51.5 ± 1.22 years. Male to female ratio was 1.5 to 1.0 out of 175 patients, 157 patients (89.7%) were of low risk group (score = 2) while 18 patients (10.3%) were in high risk group (score > 8). In low risk group, re-bleeding occurred only in 2 patients (1.2%) while in high risk group, re-bleeding occurred in 14 patients (78%). Rockall score was found to have good diagnostic accuracy with sensitivity of 87.5%, specificity of 97.48%, positive predictive value of 77.8% and negative predictive value of 98.7%. Conclusion: In cases of variceal bleed, frequency of re-bleed is less in patients who are in low risk category with lower Rockall score and high in high risk patients with higher rockall score. The Rockall score has a good diagnostic accuracy in prediction of re-bleed in variceal bleeding. (author)

  8. Primary evaluation of 99mTc-RBC imaging for the diagnosis of lower gastrointestinal bleeding

    International Nuclear Information System (INIS)

    99mTc-RBC gastrointestinal (GI) scintigraphy was performed in 10 patients with lower GI bleeding which was confirmed by operation later. The results suggested that 99mTc-RBC imaging was an effective method for the diagnosis of intestinal hemorrhage, especially the small intestine. However, there was some difficulty in accurately localizing the bleeding site due to the movement of the blood containing labelled RBC from original bleeding site to lower portion during intestinal peristalsis and also displacement of the moving colon. Therefore it is necessary to completely explore the intestine carefully and awareness of the possibility of biliary hemorrhage

    Full Text Available Bleeding changes the haemodynamics, compromising organ perfusion. In this study, the effects of bleeding followed by replacement with hydroxyethyl starch 130/0.4 (HES or lactated Ringer’s (LR on cerebral oxygenation and electroencephalogram-derived parameters were investigated. Twelve young pigs under propofol-remifentanil anaesthesia were bled 30 mL/kg and, after a 20-minute waiting period, volume replacement was performed with HES (GHES; N=6 or LR (GRL; N=6. Bleeding caused a decrease of more than 50% in mean arterial pressure (P<0.01 and a decrease in cerebral oximetry (P=0.039, bispectral index, and electroencephalogram total power (P=0.04 and P<0.01, resp., while propofol plasma concentrations increased (P<0.01. Both solutions restored the haemodynamics and cerebral oxygenation similarly and were accompanied by an increase in electroencephalogram total power. No differences between groups were found. However, one hour after the end of the volume replacement, the cardiac output (P=0.03 and the cerebral oxygenation (P=0.008 decreased in the GLR and were significantly lower than in GHES (P=0.02. Volume replacement with HES 130/0.4 was capable of maintaining the cardiac output and cerebral oxygenation during a longer period than LR and caused a decrease in the propofol plasma concentrations.

    Gastrointestinal (GI) bleeding is a common surgical problem. The aim of this study was to evaluate how insertion of the nasogastric tube may enable differentiation between upper and lower GI bleeding in patients with melena. A retrospective study involving patients admitted to our surgery division with a melena was carried out between the years 2010 and 2012. A total of 386 patients were included in the study. Of these, 279 (72.2%) patients had negative nasogastric aspirate. The sensitivity of examination of nasogastric aspirate to establish the upper GI as the source of bleeding was only 28% and the negative predictive value of a negative nasogastric aspirate was less than 1%. Most patients who initially presented with melena and were found to have upper GI bleeding had a negative nasogastric aspirate. Insertion of a nasogastric tube does not affect the clinical decision to perform upper endoscopy and should not be routinely carried out.

    During the last years most embolizations with the liquid agent Onyx have been performed in the field of neuroradiological interventions. There is minimal experience with arterial embolizations of the body trunk. 23 patients suffering from acute abdominal or thoracic bleeding underwent 28 embolizations with Onyx (17 male, 6 female, mean age 69 years). 27 interventions were technically and clinically successful. One patient with rebleeding from a jejunal artery aneurysm underwent surgery. Onyx embolizations were performed in renal, hepatic, iliac and bronchial arteries and esophageal varices. Compared with prior embolisation agents Onyx offers advantages due to good controllability. Fast arterial occlusion improves time management of patients. In comparison with prior techniques we observed a significant reduction of fluoroscopy time. Quantitative measurements demonstrated a significant higher embolisation agent contrast. (orig.)

    Full Text Available Portal hypertension is the increase in the pressure of the venous portal system, which receives around 1,500 mL/m of blood from the intestinum tenue, colon, spleen, and pancreas. A blocking of the flux or an increase in the resistance at any level of the portal tree results in an increase in the pressure in the system and the appearance of lateral circles between the portal vein and the inferior and superior, thus allowing for varicose veins to spread in the whole system. The present paper reports the case of a woman with liver cirrhosis, great ascites and bleeding out of varicose veins’ rupture at the spleen axis level, which presented the problem of differential diagnosis with other causes of hypovolemic shock. This cases resulted in the patient’s exitus.

    Introduction: Patients with gastrointestinal bleeding admitted out of hours or at the weekends may have an excess mortality rate. The literature reports around this are conflicting. Aims and methods: We aimed to analyze the outcomes of emergency endoscopies performed out of hours and over the weekends in our center. We retrospectively analyzed data from April 2008 to June 2012. Results: A total of 507 ‘high risk’ emergency gastroscopies were carried out over the study period for various indications. Patients who died within 30 days of the index procedure [22 % (114 /510)] had a significantly higher Rockall score (7.6 vs. 6.0, P < 0.0001), a higher American Society of Anesthesiologists (ASA) status (3.5 vs. 2.7, P < 0.001), and a lower systolic blood pressure (BP) at the time of the examination (94.8 vs 103, P = 0.025). These patients were significantly older (77.7 vs. 67.5 years, P = 0.006), and required more blood transfusion (5.9 versus 3.8 units). Emergency out-of-hours endoscopy was not associated with an increased risk of death [relative risk (RR) 1.09, 95 % confidence interval (CI) 1.12 – 1.95]. Whether the examination was carried out by a senior specialist registrar (senior trainee) or a consultant made no difference to the survival of the patient (RR 0.98, CI 0.77 – 1.32). Conclusion: Higher pre-endoscopy Rockall score and ASA status contributed significantly to the 30-day mortality following upper gastrointestinal bleeding, whereas lower BP tended towards significance. Outcomes did not vary with the time of the endoscopy nor was there any difference between a consultant and a senior specialist registrar led service. PMID:27004244

    Acute lower gastrointestinal bleeding (LGIB) is a common diagnosis in current practice that may warrant hospitalization and invasive management. There is a shift in the paradigm in the management of this condition away from traditional extensive operative intervention to minimally invasive radiological techniques. These newer modalities offer an opportunity to provide more accurate information on location of bleeding and subsequent management. The increased ease of access to interventional radiology units in major teaching hospitals represents an opportunity to adopt its use in the management of gastrointestinal bleeding. Further, with technological improvements, it is becoming an increasingly favoured option. Traditional endoscopic techniques have been fraught with poor vision in the acute setting, requiring the colon to be purged to aide in better visualization. The use of these newer technologies have been the subject of many reviews which highlight their efficacy in providing a road map to the bleeding site and eventual intervention. We aim to review the literature regarding the use of radiology in the management of LGIB, to provide surgeons with a discourse with regards to the approach in synthesizing the data and applying it when deciding its use.

  3. Scintigraphic detection of gastrointestinal bleeding: a review of current methods

    International Nuclear Information System (INIS)

    Recent experience with radionuclide imaging has provided the clinician with several techniques to noninvasively detect and locate sources of gastrointestinal hemorrhage. These tests can be rapidly performed and often in an ICU setting. One method used Tc-99m sulfur colloid which, in an animal model, has been shown to detect acute bleeding at rates as low as 0.1 ml/min. However, because the tracer remains in the blood for a short period of time, it may be suboptimal for identifying patients with intermittent bleeding. Tc-99m red cells is a tracer that remains within the blood and permits detection of both acute and intermittent bleeding. With tagged red cells, sites of bleeding from both the upper and lower gastrointestinal tract can be found. Both of these techniques can provide important information in the patient with suspected active gastrointestinal bleeding and aid the clinician in more effective management including the use of invasive diagnostic and therapeutic techniques

    AIM: To evaluate the effect of ranitidine on gastric mucosal changes and on GI bleeding in long distance runners.METHODS: Twenty-four long distance runners (M: 16,F: 8, age: 18.2± 1.5 years) participated in this study. A symptom questionnaire, stool hemoccult test, and upper gastrointestinal (GI) endoscopy were performed on the subjects prior to the study. The subjects took oral ranitidine (150 mg, b.i.d.) for two weeks. The upper GI endoscopy and stool Hemoccult tests were repeated after the treatment.RESULTS: Twenty-two of the 24 runners had at least one upper GI mucosal lesion before the medication. The Endoscopic improvements were seen in eleven of the 14 cases of erosive gastritis and four of the 5 cases of esophagitis. Six subjects were Heme occult positive prior to the study, but only one was positive after the medication.CONCLUSION: Gastric mucosal lesions and GI bleeding in long distance runners seem to be associated to acidrelated factors mediated by the high level of regular running. Ranitidine seems to be and effective prophylaxis to prevent gastric mucosal lesions and GI bleeding.

    Gastric polyps account for a small proportion of gastric neoplasms. Many of them presented with acute or chronic bleeding. Endoscopic polypectomy is the preferred treatment modality. However, endoscopic polypectomy is often incomplete and impossible for large polyps. Large and intramural polyps require laparotomy and excision. From June to October 1995, four patients with bleeding gastric polyps received laparoscopic resection in our unit. All were women, aged 40-78, with polyps 2-6 cm in diameter. One patient underwent emergency surgery for active bleeding. The others received elective operations. Operating time ranged from 90 to 120 min. There was no perioperative morbidity or mortality. Full diet was resumed by the 4th postoperative day. The average postoperative hospital stay was 5. 3 days (4-7). Laparoscopic resection of gastric polyp is a preferable treatment option when endoscopic treatment fails.

    To investigate the diagnostic performance of computed tomography angiography (CTA) in identifying the cause of bleeding and to determine the clinical features associated with a positive test result of CTA in patients visiting emergency department with overt gastrointestinal (GI) bleeding. We included 111 consecutive patients (61 men and 50 women; mean age: 63.4 years; range: 28-89 years) who visited emergency department with overt GI bleeding. They underwent CTA as a first-line diagnostic modality from July through December 2010. Two radiologists retrospectively reviewed the CTA images and determined the presence of any definite or potential bleeding focus by consensus. An independent assessor determined the cause of bleeding based on other diagnostic studies and/or clinical follow-up. The diagnostic performance of CTA and clinical characteristics associated with positive CTA results were analyzed. To identify a definite or potential bleeding focus, the diagnostic yield of CTA was 61.3% (68 of 111). The overall sensitivity, specificity, positive predictive value (PPV), and negative predictive value were 84.8% (67 of 79), 96.9% (31 of 32), 98.5% (67 of 68), and 72.1% (31 of 43), respectively. Positive CTA results were associated with the presence of massive bleeding (p = 0.001, odds ratio: 11.506). Computed tomography angiography as a first-line diagnostic modality in patients presenting with overt GI bleeding showed a fairly high accuracy. It could identify definite or potential bleeding focus with a moderate diagnostic yield and a high PPV. CTA is particularly useful in patients with massive bleeding.

Upper gastrointestinal bleeding (bleeding derived from a source above the ligament of Treitz, which connects the fourth portion of the duodenum to the diaphragm) is roughly four times as common as bleeding from the lower gastrointestinal tract and is a major cause of morbidity and mortality. Upper gastrointestinal bleeding is a...

    A 55-year old male patient was diagnosed with strongyloides hyper-infection with stool analysis and intestinal biopsy shortly after his chemotherapy for myeloma.He was commenced on albendazole anthelmintic therapy. After initiation of the treatment he suffered lifethreatening gastrointestinal (GI) bleeding. Repeated endoscopies showed diffuse multi-focal intestinal bleeding. The patient required huge amounts of red blood cells and plasma transfusions and correction of haemostasis with recombinant activated factor Ⅶ.Abdominal aorto-angiography showed numerous microinferior mesenteric arteries' territories. While the biopsy taken prior to the treatment with albendazole did not show evidence of vasculitis, the biopsy taken after initiation of therapy revealed leukoclastic aggregations around the vessels. These findings suggest that, in addition to direct destruction of the mucosa, vasculitis could be an important additive factor causing the massive GI bleeding during the anthelmintic treatment.This might result from substances released by the worms that have been killed with anthelmintic therapy.Current guidelines advise steroids to be tapered and stopped in case of systematic parasitic infections as they might reduce immunity and precipitate parasitic hyper-infection. In our opinion, steroid therapy might be of value in the management of strongyloides hyperinfection related vasculitis, in addition to the anthelmintic treatment. Indeed, steroid therapy of vasculitis with other means of supportive care resulted in cessation of the bleeding and recovery of the patient.

    Full Text Available Introduction: Bleeding from gums is a common feature in periodontitis patient. But abnormal bleeding from the gingiva or other areas of the oral mucosa that is difficult to control is an important clinical sign suggesting a hematological disorder. Case Report: A-40-year old male patient reported to our clinic with the chief complaint of acute gingival bleeding. There was continuous bleeding, fever since 3-4 days with weakness, retro orbital pain, and severe backache. Patient gave a history of bleeding from gums for last 24 hrs. His blood profile revealed; platelet count of 36,000, total wite blood cell (WBC count of 6000/cumm, differential leukocyte count (DLC (P45, L53, E2, and hemoglobin 12 g/dL. Patient sera was positive for dengue non-structural protein-1 antigen, anti-dengue immunoglobulin M (IgM, and anti-dengue immunoglobulin G (IgG antibodies. Discussion: Here is a case report capable of changing our vision that acute gingival bleeding can also occur in dengue fever. Dengue fever can also be considered as one of the differential diagnosis for the acute gingival bleeding.

    2015-01-01

    Full Text Available Amyloidosis is a common complication of patients with monoclonal gammopathy of undetermined significance (MGUS, smoldering multiple myeloma (SMM, and multiple myeloma (MM. This proteinaceous material can be deposited intercellularly in any organ system, including the gastrointestinal (GI tract. In the GI tract, amyloidosis affects the duodenum most commonly, followed by the stomach and colorectum. Gastric amyloidosis causes symptoms of nausea, vomiting, early satiety, abdominal pain, and GI bleeding. A case of upper GI bleeding from gastric amyloidosis is presented in a patient with SMM. Esophagogastroduodenoscopy (EGD revealed a gastric mass. Endoscopic biopsies revealed amyloid deposition in the lamina propria, consistent with gastric amyloidosis. Liquid chromatography tandem mass spectrometry performed on peptides extracted from Congo red-positive microdissected areas of paraffin-embedded stomach specimens revealed a peptide profile consistent with AL- (lambda- type amyloidosis. Based on this and multiple other case reports, we recommend that patients with GI bleeding and MGUS, SMM, or MM undergo EGD and pathologic examination of endoscopic biopsies of identified lesions using Congo red stains for amyloidosis for early diagnosis and treatment.

    Mesenteric varices can appear as massive, acute lower gastrointestinal bleeding. The small bowel or colon may be involved, varices usually developing at sites of previous surgery or inflammation in patients with portal hypertension. Two patients with alcoholic cirrhosis and protal hypertension presented with rectal bleeding. Tc-99m RBC studies demonstrated varices and extravasation into the adjacent bowel. The varices were documented by mesenteric angiography. Characteristic features of Tc-99m labeled RBC studies can identify mesenteric varices as the cause of intestinal bleeding and localize the abnormal vessels.

  18. Embolization of Bleeding Stomal Varices by Direct Percutaneous Approach

    International Nuclear Information System (INIS)

    Stomal varices can occur in patients with stoma in the presence of portal hypertension. Suture ligation, sclerotherapy, angiographic embolization, stoma revision, beta blockade, portosystemic shunt, and liver transplantation have been described as therapeutic options for bleeding stomal varices. We report the case of a 21-year-old patient with primary sclerosing cholangitis and colectomy with ileostomy for ulcerative colitis, where stomal variceal bleeding was successfully treated by direct percutaneous embolization. We consider percutaneous embolization to be an effective way of treating acute stomal bleeding in decompensated patients while awaiting decisions regarding shunt procedures or liver transplantation.

    The prevalence of diverticular diseases of the colon, including severe and persistent bleeding in Eastern countries, has increased in the last decades. The bleeding from colonic diverticula is the most common cause of acute lower gastrointestinal bleeding. Herein, we report four cases of severe and persistent bleeding of colonic diverticular disease that could be treated with a high concentration barium enema. These four cases showed a similar pattern of bleeding whose source could not be identified. Colonoscopy revealed fresh blood in the entire colon and many diverticula were noted throughout the colon. No active bleeding source was identified, but large adherent clots in some diverticula were noted. After endoscopic and angiographic therapies failed, therapeutic barium enema stopped the severe bleeding. These patients remained free of re-bleeding in the follow-up period (range 17-35 mo) after the therapy. We report the four case series of therapeutic barium enema and reviewed the literature pertinent to this procedure.

    Gastrointestinal (GI) metastasis of hepatocellular carcinoma is very rare. This is the first report of post-transplantation gastric metastasis. A 43-year-old man with a history of hepatitis B-related hepatocellular carcinoma (HCC) in the right anterior segment of the liver received an orthotopic liver transplant. Three months after the transplantation, pulmonary metastasis was found by chest computed tomography, and he received 1 course of gamma knife treatment. He complained of melena with anemia 17 months post liver transplantation. Abdominal CT scan showed new occupying lesions in the liver and a mass in the stomach and around the spleen with embolus in the splenic vein. Endoscopy revealed a large irregular cauliflower-like mass in fundus with ulceration and bleeding on the surface. He received symptomatic treatment, but died of cancer-related bleeding 4 months later. GI bleeding may due to gastric metastasis after liver transplantation.

  3. Detection of gastrointestinal bleeding with /sup 99m/Tc-sulfur colloid

    International Nuclear Information System (INIS)

    We have developed a single scintigraphic technique to detect and localize the site of bleeding in the gastrointestinal tract. This examination requires only intravenous administration of /sup 99m/Tc sulfur colloid and imaging of the abdomen. Very shortly after the introduction of the radiopharmaceutical, a fraction of the injected activity extravasates at the bleeding site and is eliminated from the circulation. This phenomenon is repeated each time the blood recirculates adding another, but smaller fraction to the extravasated activity at the site of hemorrhage. Because of continued clearance of the radiopharmaceutical from the vascular pool by the reticuloendothelial system, a contrast is eventually reached between the site of bleeding and surrounding background. Based on animal experiments bleeding rates as low as .05-0.1 cc/min can be detected with this technique. The sensitivity of the approach in the detection of the site of hemorrhage is significantly higher than arteriography or other techniques which utilize radioactive blood pool indicators. We have mainly used this technique in the evaluation of patients with GI bleeding. In more than 25 patients with negative scintigrams for hemorrhage, arteriography showed no evidence of bleeding. In 38 patients with scintigraphic evidence of bleeding. In 38 patients with scintigraphic evidence of hemorrhage, arteriograms were positive for bleeding in les than 50% of the cases. No false positive results have been noted in the latter group. This technique appears to offer a simple, practical and reliable approach to the evaluation of patients with gastrointestinal bleeding

  5. Comparison of four technetium-99m radiopharmaceuticals for detection and localization of gastrointestinal bleeding in a sheep model

    International Nuclear Information System (INIS)

    Four Tc-99 radiopharmaceuticals, Tc-99m sulphur colloid, Tc-99m red blood cells (RBCs), Tc-99m mercaptoacetyltriglycine (MAG3), and Tc-99m DTPA, were studied in an experimental animal model for detection and localization of gastrointestinal (GI) bleeding site in both the upper and lower abdomen. With Tc-99m sulphur colloid and Tc-99m RBCs, it was possible to detect and localize the GI bleeding site in the lower abdomen. With Tc-99m MAG3, it was possible to visualize the bleeding site in both the upper and lower abdomen. However, Tc-99m MAG3 is partially excreted by the liver into the bile, hence it will be difficult to use Tc-99m MAG3 to localize the GI bleeding site in the lower abdomen. With Tc-99m DTPA, it was possible to detect and localize the GI bleeding site simultaneously in both upper and lower abdomen. The overall background radioactivity was reduced considerably by diuresis with frusemide and catheterization of the urinary bladder

  8. Is there still a role for intraoperative enteroscopy in patients with obscure gastrointestinal bleeding?

    Directory of Open Access Journals (Sweden)

    Pedro Monsanto

    2012-04-01

    Full Text Available Background: in 21st century, endoscopic study of the small intestine has undergone a revolution with capsule endoscopy and balloon-assisted enteroscopy. The difficulties and morbidity associated with intraoperative enteroscopy, the gold-standard in the 20th century, made this technique to be relegated to a second level. Aims: evaluate the actual role and assess the diagnostic and therapeutic value of intraoperative enteroscopy in patients with obscure gastrointestinal bleeding. Patients and methods: we conducted a retrospective study of 19 patients (11 males; mean age: 66.5 ± 15.3 years submitted to 21 IOE procedures for obscure GI bleeding. Capsule endoscopy and double balloon enteroscopy had been performed in 10 and 5 patients, respectively. Results: with intraoperative enteroscopy a small bowel bleeding lesion was identified in 79% of patients and a gastrointestinal bleed-ing lesion in 94%. Small bowel findings included: angiodysplasia (n = 6, ulcers (n = 4, small bowel Dieulafoy's lesion (n = 2, bleed-ing from anastomotic vessels (n = 1, multiple cavernous hemangiomas (n = 1 and bleeding ectopic jejunal varices (n = 1. Agreement between capsule endoscopy and intraoperative enteroscopy was 70%. Endoscopic and/or surgical treatment was used in 77.8% of the patients with a positive finding on intraoperative enteroscopy, with a rebleeding rate of 21.4% in a mean 21-month follow-up period. Procedure-related mortality and postoperative complications have been 5 and 21%, respectively. Conclusions: intraoperative enteroscopy remains a valuable tool in selected patients with obscure GI bleeding, achieving a high diagnostic yield and allowing an endoscopic and/or surgical treatment in most of them. However, as an invasive procedure with relevant mortality and morbidity, a precise indication for its use is indispensable.

    Abnormal uterine bleeding (AUB) is a common and debilitating condition with high direct and indirect costs. AUB frequently co-exists with fibroids, but the relationship between the two remains incompletely understood and in many women the identification of fibroids may be incidental to a menstrual bleeding complaint. A structured approach for establishing the cause using the Fédération International de Gynécologie et d'Obstétrique (FIGO) PALM-COEIN (Polyp, Adenomyosis, Leiomyoma, Malignancy (and hyperplasia), Coagulopathy, Ovulatory disorders, Endometrial, Iatrogenic and Not otherwise classified) classification system will facilitate accurate diagnosis and inform treatment options. Office hysteroscopy and increasing sophisticated imaging will assist provision of robust evidence for the underlying cause. Increased availability of medical options has expanded the choice for women and many will no longer need to recourse to potentially complicated surgery. Treatment must remain individualised and encompass the impact of pressure symptoms, desire for retention of fertility and contraceptive needs, as well as address the management of AUB in order to achieve improved quality of life.

    Full Text Available Dabigatran-absorption is dependent on the intestinal P-glycoprotein (P-gp-system, and P-gp activity is modulated by several drugs. We report an 83-old female with atrial fibrillation who developed gastrointestinal bleeding. She was under a therapy with non-steroidal anti-inflammatory drugs (NSAID and P-gp-modulating drugs and renal function was impaired. We conclude that NSAID and P-gp-modulating drugs should be avoided in dabigatran-treated patients. If renal function deteriorates the dabigatran-dosage should be reduced or the therapy should be stopped. There is an urgent need to increase knowledge about drug interactions with dabigatran.

    Acute gastrointestinal bleeding in patients with liver cirrhosis is associated with a high mortality. Ileal varices and collaterals from ectopic vessels are extremely rare, encountered in less than 5% of the cirrhotic patients. The diagnosis is frequently delayed because the regular diagnostic methods such as gastroscopy or colonoscopy are unsuccessful in accurate the source of bleeding in the majority of the cases. We report an unusual case of massive and uncontrollable lower intestinal bleeding from ileal varices with right ovarian vein anastomosis in a 56 year-old female patient with liver cirrhosis and previous history of abdominal and pelvic surgery. The accurate angiographic and computed tomography diagnosis allowed fast decompression of the portal venous system using a transjugular intrahepatic portosystemic shunt. (orig.) [German] Akute gastrointestinale Blutungen sind bei Leberzirrhosepatienten mit einer hohen Mortalitaet verbunden. Ileale Varizen und Kollateralen aus anderen ektopen Gefaessen des Darms sind extrem selten und treten bei weniger als 5% aller Zirrhosepatienten auf.

  17. Antidepressant-warfarin interaction and associated gastrointestinal bleeding risk in a case-control study.

    Directory of Open Access Journals (Sweden)

    Hedi Schelleman

    Full Text Available BACKGROUND: Bleeding is the most common and worrisome adverse effect of warfarin therapy. One of the factors that might increase bleeding risk is initiation of interacting drugs that potentiate warfarin. We sought to evaluate whether initiation of an antidepressant increases the risk of hospitalization for gastrointestinal bleeding in warfarin users. METHODOLOGY/PRINCIPAL FINDINGS: Medicaid claims data (1999-2005 were used to perform an observational case-control study nested within person-time exposed to warfarin in those ≥18 years. In total, 430,455 warfarin users contributed 407,370 person-years of warfarin use. The incidence rate of hospitalization for GI bleeding among warfarin users was 4.48 per 100 person-years (95% CI, 4.42-4.55. Each gastrointestinal bleeding cases was matched to 50 controls based on index date and state. Warfarin users had an increased odds ratio of gastrointestinal bleeding upon initiation of citalopram (OR = 1.73 [95% CI, 1.25-2.38], fluoxetine (OR = 1.63 [95% CI, 1.11-2.38], paroxetine (OR = 1.64 [95% CI, 1.27-2.12], amitriptyline (OR = 1.47 [95% CI, 1.02-2.11]. Also mirtazapine, which is not believed to interact with warfarin, increased the risk of GI bleeding (OR = 1.75 [95% CI, 1.30-2.35]. CONCLUSIONS/SIGNIFICANCE: Warfarin users who initiated citalopram, fluoxetine, paroxetine, amitriptyline, or mirtazapine had an increased risk of hospitalization for gastrointestinal bleeding. However, the elevated risk with mirtazapine suggests that a drug-drug interaction may not have been responsible for all of the observed increased risk.

  18. Multi-detector CT angiography for lower gastrointestinal bleeding: can it select patients for endovascular intervention?

    International Nuclear Information System (INIS)

    Full text: This is a retrospective review of the results at our institution of using multi-detector CT angiography (CTA) to localise lower gastrointestinal (GI) bleeding. We hypothesised that in our patient population: (i) CTA was unlikely to demonstrate bleeding in patients who were haemodynamically stable; (ii) in haemodynamically unstable patients in whom CTA was undertaken, the results could be used to select patients who would benefit from catheter angiography; and (iii) in haemodynamically unstable patients in whom CTA was undertaken, a subgroup of patients could be identified who would benefit from primary surgical treatment, avoiding invasive angiography completely. A retrospective review was conducted of the clinical records of all patients undergoing CTA for lower GI haemorrhage at our institution between 1 January 2005 and 30 June 2007. Out of the 20 patients examined, 10 had positive CTAs demonstrating the bleeding site. Nine were haemodynamically unstable at the time of the study. Four patients with positive CT angiograms were able to be treated directly with surgery and avoided invasive angiography. Ten patients had negative CTAs. Four of these were haemodynamically unstable, six haemodynamically stable. Only one required intervention to secure haemostasis, the rest stopped spontaneously. No haemodynamically stable patient who had a negative CTA required intervention. CTA is a useful non-invasive technique for localising the site of lower GI bleeding. In our patient population, in the absence of haemodynamic instability, the diagnostic yield of CTA was low and bleeding was likely to stop spontaneously. In haemodynamically unstable patients, a positive CTA allowed patients to be triaged to surgery or angiography, whereas there was a strong association between a negative CTA and spontaneous cessation of bleeding.

    2015-01-01

    Non-variceal upper gastrointestinal bleeding(UGIB) is defined as bleeding proximal to the ligament of Treitz in the absence of oesophageal, gastric or duodenal varices. The clinical presentation varies according to the intensity of bleeding from occult bleeding to melena or haematemesis and haemorrhagic shock. Causes of UGIB are peptic ulcers, Mallory-Weiss lesions,erosive gastritis, reflux oesophagitis, Dieulafoy lesions or angiodysplasia. After admission to the hospital a structured approach to the patient with acute UGIB that includes haemodynamic resuscitation and stabilization as well as pre-endoscopic risk stratification has to be done. Endoscopy offers not only the localisation of the bleeding site but also a variety of therapeutic measures like injection therapy, thermocoagulation or endoclips. Endoscopic therapy is facilitated by acid suppression with proton pump inhibitor(PPI) therapy. These drugs are highly effective but the best route of application(oral vs intravenous) and the adequate dosage are still subjects of discussion. Patients with ulcer disease are tested for Helicobacter pylori and eradication therapy should be given if it is present. Non-steroidal antiinflammatory drugs have to be discontinued if possible. If discontinuation is not possible, cyclooxygenase-2 inhibitors in combination with PPI have the lowest bleeding risk but the incidence of cardiovascular events is increased.

    A porcine model for an acute lethal arterial subdural bleeding in man is presented. Blood from the abdominal aorta was led via an electronic drop recorder into a collapsed intracranial subdural rubber balloon. Systemic arterial pressure (SAP), two intracranial pressures and 6 other vital parameters were monitored continuously in spontaneously breathing (n = 4) and mechanically ventilated (n = 4) pigs. In both animal groups bleeding caused an immediate rise in intracranial pressures (ICP) with transtentorial pressure gradients developing. As a result the cerebral perfusion pressures (CPP) decreased progressively, leading to an isoelectric EEG. In spontaneously breathing animals, the pressure changes resulted in apnoea within 2-4 minutes, irregularities in heart rhythm and in a marked rise in SAP (the Cushing reaction). A final collapse of all pressures occurred after 222 +/- 68 sec at a mean bleeding volume of 10.3 +/- 1.9 ml. In contrast, in mechanically ventilated animals, the course of bleeding was less dramatic. No change in cardiac rhythm or rise in SAP appeared despite a larger mean bleeding volume (12.0 +/- 1.6 ml). Instead, SAP slowly fell, reaching a level of approximately 40 mm Hg within 1 hour, while CPP concomitantly decreased from 120 mm Hg to 15 mm Hg. The findings in this and in a parallel study are explained in terms of the intracranial volume tolerance concept (Zwetnow et al. 1986). The beneficial effect of assisted ventilation on the course of subdural bleeding is multifactorial, involving both metabolic and mechanical mechanisms. PMID:8475809

    2014-02-01

    Hemospray is a haemostatic agent licensed for endoscopic haemostasis of non-variceal upper gastrointestinal bleeding (NVUGIB) in Europe and Canada. Hemospray has been shown to be safe and effective in achieving haemostasis in bleeding peptic ulcers in a prospective clinical study and several further case series have described the use of hemospray in other non-variceal causes of gastrointestinal bleeding. Portal hypertensive gastropathy and colopathy are common in patients with portal hypertension. As hemospray is an easy to apply, non-contact method, which can cover large areas of mucosa, it may be of benefit in acute non-variceal portal hypertensive bleeding. We present data from the first four consecutive patients presenting to our institution with acute haemorrhage secondary to non-variceal diffuse portal hypertensive bleeding treated with hemospray.

    Full Text Available Abstract Background Endoscopic band ligation (EBL is generally accepted as the treatment of choice for bleeding from esophageal varices. It is also used for secondary prophylaxis of esophageal variceal hemorrhage. However, there is no data or guidelines concerning endoscopic control of ligation ulcers. We conducted a retrospective study of EBL procedures analyzing bleeding complications after EBL. Methods We retrospectively analyzed data from patients who underwent EBL. We analyzed several data points, including indication for the procedure, bleeding events and the time interval between EBL and bleeding. Results 255 patients and 387 ligation sessions were included in the analysis. We observed an overall bleeding rate after EBL of 7.8%. Bleeding events after elective treatment (3.9% were significantly lower than those after treatment for acute variceal hemorrhage (12.1%. The number of bleeding events from ligation ulcers and variceal rebleeding was 14 and 15, respectively. The bleeding rate from the ligation site in the group who underwent emergency ligation was 7.1% and 0.5% in the group who underwent elective ligation. Incidence of variceal rebleeding did not vary significantly. Seventy-five percent of all bleeding episodes after elective treatment occurred within four days after EBL. 20/22 of bleeding events after emergency ligation occured within 11 days after treatment. Elective EBL has a lower risk of bleeding from treatment-induced ulceration than emergency ligation. Conclusions Patients who underwent EBL for treatment of acute variceal bleeding should be kept under medical surveillance for 11 days. After elective EBL, it may be reasonable to restrict the period of surveillance to four days or even perform the procedure in an out-patient setting.

  9. Uranium GI absorption coefficients for young children

    International Nuclear Information System (INIS)

    Uranium is ubiquitously found in drinking water and food. The absorption fraction (f1) is an important parameter in risk assessment of uranium burdens from ingestion. Although absorption of uranium from the gastrointestinal tract (GI) has been studied extensively in both animals and humans in the past, human data among young children are rare. In a previous study based on measurements of uranium concentration in only 11 bone-ash samples collected by Health Canada, the GI absorption coefficient for uranium ingestion by infants, about 3 months of age were determined. The result was 0.256 which was much higher than the ICRP recommended f1 values of 0.04 for infants and 0.02 for anyone more than 1 year of age. To extend the study, a total of 73 bone-ash samples were selected for children ranging in age from 0 to 7 years. The estimated absorption coefficients were 0.093±0.113 for infants, and 0.050±0.032 for 1 - 7 years of age. This study provides human absorption coefficients of ingested uranium for young children of two age groups. (author)

    Gastrointestinal bleeding represents a common medical emergency, with considerable morbidity and mortality rates, and a prompt diagnosis is essential for a better prognosis. In such a context, endoscopy is the main diagnostic tool; however, in cases where the gastrointestinal hemorrhage is massive, the exact bleeding site might go undetected. In addition, a trained professional is not always present to perform the procedure. In an emergency setting, optical colonoscopy presents limitations connected with the absence of bowel preparation, so most of the small bowel cannot be assessed. Scintigraphy cannot accurately demonstrate the anatomic location of the bleeding and is not available at emergency settings. The use of capsule endoscopy is inappropriate in the acute setting, particularly in the emergency department at night, and is a highly expensive method. Digital angiography, despite its high sensitivity, is invasive, presents catheterization-related risks, in addition to its low availability at emergency settings. On the other hand, computed tomography angiography is fast, widely available and minimally invasive, emerging as a promising method in the diagnostic algorithm of these patients, being capable of determining the location and cause of bleeding with high accuracy. Based on a critical literature review and on their own experience, the authors propose a computed tomography angiography protocol to assess the patient with gastrointestinal bleeding. (author)

    The new oral anticoagulants directly inhibit either thrombin (Dabigatran, Pradaxa®,) or activated Factor X (rivaroxaban, Xarelto®, and apixaban, Eliquis®) and have been approved for thromboprophylaxis after hip and knee replacement surgery and stroke prevention in non-valvular atrial fibrillation. Moreover, rivaroxaban has been approved for the treatment of deep venous thrombosis, prevention of pulmonary embolism and anticoagulation after acute myocardial infarction. The direct FXa-inhibitor edoxaban (Lixiana®) expects approval for the prevention of stroke in atrial fibrillation in Germany in 2014. The half lives of all direct anticoagulants range between 8 and 17 hours. Dabigatran (Pradaxa®) and rivaroxaban (Xarelto®) are mainly excreted by the kidneys, apixaban (Eliquis®) by the liver (75%) and edoxaban (Lixiana®) by the kidneys (40%) and the faeces in 60%. Prior to surgery a shorter cessation is expected compared to the vitamin k antagonists phenprocoumon (Marcumar®, Falithrom®) and warfarin (Coumadin®). For acute bleedings caused by the direct thrombin inhibitor dabigatran (Pradaxa®) hemodialysis is recommended to eliminate the drug from the plasma. Due to the high protein binding the direkt FXa-inhibitors rivaroxaban (Xarelto®) and apixaban (Eliquis®) can not be hemodialysed. For edoxaban (Lixiana®) no data on elimination by renal replacement therapy are available. In case of life-threatening bleeding the replacement of a prothrombin complex preparation (PCC) containing the factors II, VII, IX and X and, second line, activated factor concentrates as recombinant factor VIIa or activated prothrombin complex preparations are recommended.

    Direct oral anticoagulants (DOAC) are recommended for stroke prevention in atrial fibrillation and for the treatment of venous thromboembolism. However, they are associated with hemorrhagic complications. Management of DOAC-induced bleeding remains challenging. Activated or non-activated prothrombin concentrates are proposed, although their efficacy to reverse DOAC is uncertain. Therapeutic options also include antidotes: idarucizumab, antidote for dabigatran, has been approved for use whereas andexanet alpha, antidote for anti-Xa agents, and aripazine, antidote for all DOAC, are under development. Other options include hemodialysis for the treatment of dabigatran-associated bleeding and administration of oral charcoal if recent DOAC ingestion. DOAC plasma concentration measurement is necessary to guide DOAC reversal. We propose an update on DOAC-associated bleeding, integrating the availability of dabigatran antidote and the critical place of DOAC concentration measurements. PMID:27297642

    Diverticular hemorrhage is the most common reason for lower gastrointestinal bleeding (LGIB) with substantial cost of hospitalization and a median length of hospital stay of 3 days. Bleeding usually is self-limited in 70-80% of cases but early rebleeding is not an uncommon problem that can be reduced with proper endoscopic therapies. Colonoscopy is recommended as first-line diagnostic and therapeutic approach. In the vast majority of patients diverticular hemorrhage can be readily managed by interventional endotherapy including injection, heat cautery, clip placement, and ligation to achieve endoscopic hemostasis. This review will serve to highlight the various interventions available to endoscopists with specific emphasis on superior modalities in the endoscopic management of diverticular bleeding.

    Full Text Available Primary gastrointestinal (GI lymphoma accounts for 30–50% of all extranodal non-Hodgkin’s lymphomas, making the GI tract the most common site of extranodal non-Hodgkin’s lymphomas. Most GI lymphomas belong to the B cell lineage. Burkitt lymphoma (BL is a highly aggressive mature B cell neoplasm that occurs in three forms: endemic, sporadic, and immunodeficiency-associated. Sporadic BL accounts for 1–2% of all adult lymphomas and usually presents as an abdominal manifestation of extranodal disease involving the distal ileum or cecum. Primary BL of the duodenum is rare. However, this report emphasizes the importance of awareness of the malignancy potential of duodenal polyps. We report the case of a 70-year-old woman admitted to our ward with upper GI bleeding due to duodenal polyps. An upper GI endoscopic examination showed button-like polyps with central depression, and an immunohistochemical study of the polyps revealed a high-grade B cell malignancy (BL. Consequently, the patient was treated with aggressive chemotherapy. The tumors regressed after chemotherapy. Although primary duodenal Burkitt lymphoma is very rare, the possibility of malignancy should be considered if a patient presents with duodenal button-like polyps with a central depressed surface.

    Full Text Available Introduction: Video laryngoscopy (VL has been advocated for several aspects of emergency airway management; however, there are still concerns over its use in select patient populations such as those with large volume hematemesis secondary to gastrointestinal (GI bleeds. Given the relatively infrequent nature of this disease process, we sought to compare intubation outcomes between VL and traditional direct laryngoscopy (DL in patients intubated with GI bleeding, using the third iteration of the National Emergency Airway Registry (NEARIII. Methods: We performed a retrospective analysis of a prospectively collected national database (NEARIII of intubations performed in United States emergency departments (EDs from July 1, 2002, through December 31, 2012. All cases where the indication for intubation was “GI bleed” were analyzed. We included patient, provider and intubation characteristics. We compared data between intubation attempts initiated as DL and VL using parametric and non-parametric tests when appropriate. Results: We identified 325 intubations, 295 DL and 30 VL. DL and VL cases were similar in terms of age, sex, weight, difficult airway predictors, operator specialty (emergency medicine, anesthesia or other and level of operator training (post-graduate year 1, 2, etc. Proportion of successful first attempts (DL 261/295 (88.5% vs. VL 28/30 (93.3% p=0.58 and Cormack-Lehane grade views (p=0.89 were similar between devices. The need for device change was similar between DL [2/295 (0.7% and VL 1/30 (3.3%; p=0.15]. Conclusion: In this national registry of intubations performed in the ED for patients with GI bleeds, both DL and VL had similar rates of success, glottic views and need to change devices.

    Full Text Available To estimate objectively vessels network remodeling in duodenal mucosa after ulcer bleeding the morphometric analysis of marginal ulcer zone biopsies was performed in 32 patients. It was shown that reparation is accompanied with chronic inflammation and acute alteration of microcirculation. Injection hemostasis led to enhancement of microcirculation, development of edema and ischemic alteration of mucosal tissues. Acute neutrophilic infiltration during 1 day was changed on 3 day with granular tissue development and angiogenesis stimulation. Intensification and prolongation of angiogenesis paral-leled with lymphocytes infiltration after 7 days resulted to villi dysmorphogenesis and changes in cellular content of intestinal epithelium.

    To assess the clinical outcomes of the transcatheter microcoil embolization in patients with active lower gastrointestinal (LGI) bleeding in the small bowel, as well as to compare the mortality rates between the two groups based on the visualization or non-visualization of the bleeding focus determined by an angiography. We retrospectively evaluated all of the consecutive patients who underwent an angiography for treatment of acute LGI bleeding between January 2003 and October 2007. In total, the study included 36 patients who underwent a colonoscopy and were diagnosed to have an active bleeding in the LGI tracts. Based on the visualization or non-visualization of the bleeding focus, determined by an angiography, the patients were classified into two groups. The clinical outcomes included technical success, clinical success (no rebleeding within 30 days), delayed rebleeding (> 30 days), as well as the major and minor complication rates. Of the 36 patients, 17 had angiography-proven bleeding that was distal to the marginal artery. The remaining 19 patients did not have a bleeding focus based on the angiography results. The technical and clinical success rates of performing transcatheter microcoil embolizations in patients with active bleeding were 100% and 88%, respectively (15 of 17). One patient died from continued LGI bleeding and one patient received surgery to treat the continued bleeding. There was no note made on the delayed bleeding or on the major or minor complications. Of the 19 patients without active bleeding, 16 (84%) did not have recurrent bleeding. One patient died due to continuous bleeding and multi-organ failure. The superselective microcoil embolization can help successfully treat patients with active LGI bleeding in the small bowel, identified by the results of an angiography. The mortality rate is not significantly different between the patients of the visualization and non-visualization groups on angiography.

    @@ Although the number of hospitalizations for nonvariccal gastrointestinal bleeding has decreased in recent years, acute upper gastrointestinal hemorrhage continues to be a common reason for hospital admission, and peptic ulcers account for at least fifty percent of all cases. Despite the fact that bleeding from ulcers ceases spontaneously in approximately 80% of patients, it is still a diagnosis associated with substantial medical costs and significant morbidity and mortality, the latter ranging between 8 and 14%[1], especially in the elderly.

    We report a rare case of a small-bowel lymphangioma causing massive gastrointestinal (GI) bleeding that we successfully diagnosed and treated using double-balloon enteroscopy (DBE).An 81-year-old woman suffering from repeated GI bleeding of unknown origin underwent a capsule endoscopy at a previous hospital.She was suspected of having bleeding from the jejunum,and was referred to our department for diagnosis and treatment.An oral DBE revealed a 20 mmx 10 mm,regularly surfaced,white to yellowish,elongated,pedunculated jejunal polyp with small erosions at 10 cm distal to the ligament of Treiz.Since no other source of bleeding was identified by endoscopy in the deep jejunum,an endoscopic polypectomy (EP) was performed for this lesion.A subsequent histopathological examination of the resected polyp showed clusters of lymphatic vessels with marked cystic dilatation in the submucosa and the deep layer of the lamina propria mucosae.These characteristics are consistent with the typical features of small-bowel lymphangioma with erosions.Although clipping hemostasis was performed during EP,re-bleeding occurred.Finally,a complete hemostasis was achieved by performing an additional argon plasma coagulation.

    Tc99m-labelled red cells were applied in 103 investigations of 91 patients to detect and localize occult gastrointestinal (GI) bleeding. In 60 examinations, GI-bleeding was proven. Correct localization of the bleeding site was achieved in 54 investigations. In 3 patients, bleeding from the lower intestinal tract could be positively excluded. These results were obtained in patients representing a negative selection, having undergone repeated endoscopy and angiography without positive result. 40% of all the bleeding sites were detected within 1 h. after tracer application, 25% only after a delay of 6 hrs. or more. To obtain good results, the whole investigation can become very time consuming and has to be performed according to a strict protocol. In addition, a tracer with high specificity to the intravasal space and high long-term stability has to be applied. Those requirements are met best by red cells labelled with Tc99m-according to a mixed in vivo/in vitro protocol.

    Full Text Available Background. GI (gastrointestinal bleeding can be due to a variety of etiologies ranging from being common like bleeding peptic ulcer disease or esophageal varices. One of the rarely documented causes is the Dieulafoy lesion which is known as an abnormally large ectatic artery that penetrates the gut wall, occasionally eroding through the mucosa causing massive bleeding. In addition to that, we refer to the uncommon presentation of Dieulafoy lesion itself as it is well known to be found in the stomach, esophagus, duodenum, and jejunum but not the ascending colon as in our case. The patient had a coexisting ITP (idiopathic thrombocytopenic purpura that was resistant to different therapies. Case Report. We report a case of a 48-year-old Egyptian female known for chronic ITP resistant to treatment. The patient presented with bright red bleeding per rectum and severe life threatening anemia. Endoscopic study showed a Dieulafoy lesion. Endoscopic clipping was successful in controlling the bleeding. Conclusion. Dieulafoy lesion is a rare reason for GI bleeding and can present in common or unexpected places. Also extreme caution should be used in patients with bleeding tendency due to different reasons, like ITP in our case.

    Gastroccult reagent was used every 4 h to detect blood in gastric juice in 41 ICU patients at risk of GI bleeding (GB) and receiving antacid prophylaxis (gastric pH greater than 3.5). Of the present patients, 27% (11/41) had at least one episode of occult GB (three consecutive positive determinations; a total of 14 episodes). Endoscopy identified acute gastroduodenal mucosal lesions (stress ulcers) as the most frequent lesion in this group (eight patients). Sepsis was the most frequent underlying condition associated with occult GB due to stress ulcer. Hematemesis occurred in 36% (4/11) of patients with occult GB and was due to stress ulcer in three patients and to benign gastric tumor in one. No overt GB occurred in the absence of previous occult GB. We conclude that: a) risk of GB persists in critically ill ICU patients in spite of antacid prophylaxis (gastric pH greater than 3.5); b) high-risk patients can be identified through periodic testing for the presence of blood in gastric juice using the reagent; c) when occult GB occurs, treatment should be based on the endoscopy results. In the absence of acute gastroduodenal mucosal lesions, antacid prophylaxis should not be modified, and specific treatment of the identified lesion(s) should be initiated. In the presence of stress lesions, antacid prophylaxis should be reinforced if the pH of the gastric content is less than 3.5 and a septic complication should be actively sought if the pH is greater than 3.5.

    Dabigatran was as effective as warfarin for the acute treatment of venous thromboembolism in the RE-COVER and RE-COVER II trials. We compared the incidence of bleeding with dabigatran versus warfarin in pooled data from these studies. The localisation, bleeding severity, and the impact of key factors on the incidence of bleeding, were compared between the dabigatran and warfarin treatment group. Altogether, 2553 patients received dabigatran and 2554 warfarin, each for a mean of 164 days. The incidence of any bleeding event was significantly lower with dabigatran (hazard ratio [HR] 0.70; 95% confidence interval [CI], 0.61-0.79), as was the incidence of the composite of MBEs and clinically relevant non-major bleeding events (HR 0.62; 95% CI, 0.50-0.76). The incidence of major bleeding events (MBEs) was also significantly lower with dabigatran in the double-dummy phase (HR, 0.60; 95%CI, 0.36-0.99) but not statistically different between the two treatment arms when the entire treatment period is considered (HR 0.73 95% CI, 0.48-1.11). Increasing age, reduced renal function, Asian ethnicity, and concomitant antiplatelet therapy were associated with higher bleeding rates in both treatment groups. The reduction in bleeding with dabigatran compared to warfarin was consistent among the subgroups and with a similar pattern for intracranial, and urogenital major bleeding. In conclusion, treatment of venous thromboembolism with dabigatran is associated with a lower risk of bleeding compared to warfarin. This reduction did not differ with respect to the location of bleeding or among predefined subgroups.

    AIM: To identify optimum timing to maximize diagnostic yield by capsule endoscopy (CE) in patients with obscure gastrointestinal bleeding (OGIB).METHODS: We identified patients who underwent CE at our institution from August 2003 to December 2009.Patient medical records were reviewed to determine type of OGIB (occult, overt), CE results and complications,and timing of CE with respect to onset of bleeding.RESULTS: Out of 385 patients investigated for OGIB,284 (74%) had some lesion detected by CE. In 222 patients (58%), definite lesions were detected that could unequivocally explain OGIB. Small bowel ulcer/erosions secondary to Crohn's disease, tuberculosis or non-steroidal anti-inflammatory agent use were the commonest lesions detected. Patients with overt GI bleeding for <48 h before CE had the highest diagnostic yield (87%).This was significantly greater (P < 0.05) compared to that in patients with overt bleeding prior to 48 h (68%),as well as those with occult OGIB (59%).CONCLUSION: We established the importance of early CE in management of OGIB. CE within 48 h of overt bleeding has the greatest potential for lesion detection.

    Obscure gastrointestinal bleeding (OGIB) is defined as bleeding of an unknown origin that persists or recurs after negative initial upper and lower endoscopies.Several techniques,such as endoscopy,arteriography,scintigraphy and barium radiology are helpful for recognizing the bleeding source;nevertheless,in about 5%-10% of cases the bleeding lesion cannot be determined.The development of videocapsule endoscopy (VCE) has permitted a direct visualization of the small intestine mucosa.We will analyze those techniques in more detail.The diagnostic yield of CE for OGIB varies from 38% to 93%,being in the higher range in those cases with obscure-overt bleeding.

    The GI brokering suite provides the discovery, access, and semantic Brokers (i.e. GI-cat, GI-axe, GI-sem) that empower a Brokering framework for multi-disciplinary and multi-organizational interoperability. GI suite has been successfully deployed in the framework of several programmes and initiatives, such as European Union funded projects, NSF BCube, and the intergovernmental coordinated effort Global Earth Observation System of Systems (GEOSS). Each GI suite Broker facilitates interoperability for a particular functionality (i.e. discovery, access, semantic extension) among a set of brokered resources published by autonomous providers (e.g. data repositories, web services, semantic assets) and a set of heterogeneous consumers (e.g. client applications, portals, apps). A wide set of data models, encoding formats, and service protocols are already supported by the GI suite, such as the ones defined by international standardizing organizations like OGC and ISO (e.g. WxS, CSW, SWE, GML, netCDF) and by Community specifications (e.g. THREDDS, OpenSearch, OPeNDAP, ESRI APIs). Using GI suite, resources published by a particular Community or organization through their specific technology (e.g. OPeNDAP/netCDF) can be transparently discovered, accessed, and used by different Communities utilizing their preferred tools (e.g. a GIS visualizing WMS layers). Since Information Technology is a moving target, new standards and technologies continuously emerge and are adopted in the Earth Science context too. Therefore, GI Brokering suite was conceived to be flexible and accommodate new interoperability protocols and data models. For example, GI suite has recently added support to well-used specifications, introduced to implement Linked data, Semantic Web and precise community needs. Amongst the others, they included: DCAT: a RDF vocabulary designed to facilitate interoperability between Web data catalogs. CKAN: a data management system for data distribution, particularly used by

    Full Text Available Background. Although relatively rare, gastric vascular anomalies can be recognized as a source of both chronic and acute blood loss, most often presenting as long term iron deficiency anemia, rarely as severe acute gastrointestinal bleeding. Case report. We present five patients with various gastric vascular anomalies, diagnosed during the year of 2003. in the Clinical Hospital Center Zemun. The diagnosis was based on endoscopic appearances, clinical history and characteristic histological findings. Gastric vascular anomalies presented in our review were: portal hypertensive gastropathy, gastric antral vascular ectasia, angiodysplasia, hereditary hemorrhagic telangiectasia and Dieulafoy lesion. The used treatment modalities included surgery and various endoscopic techniques (schlerotherapy, argon plasma coagulation. Conclusion. Patients presented with chronic iron deficiency anemia or acute and recurrent gastrointestinal hemorrhage should be considered as having one of gastric vascular anomalies.

    Arachidonic acid (AA), when cleaved from phospholipids by cytosolic phospholipase A2 alpha (cPLA2a), generates eicosanoids, with pro-hemostatic, pro-inflammatory, vasoactive and gastro-protective functions. We describe a patient (27-year-old man) and his twin-sister with early-onset bleeding diathesis and recurrent gastro-intestinal (GI) ulcers. Platelet aggregation/δ-granules secretion by collagen was impaired, but normal by AA; serum levels of thromboxane (Tx) B2 and 12-hydroxyeicosatetraenoic acid, and urinary levels of 11-dehydro-TxB2 were extremely low. Patients were homozygous for 1723G>C transition in PLA2G4A gene, which changed the codon for Asp575 to His. GI ulcers affected 5/14 heterozygous ( 60 years) family members; none had bleeding diathesis. The proband, his sister and mother also had mildly reduced factor XI levels. Platelet messenger RNA expression did not differ among subjects with different PLA2G4A genotypes. Conversely, platelet cPLA2a was undetectable by Western Blotting in the proband and his sister, and decreased in 1723G>C heterozygous subjects, suggesting that the variant is transcribed, but not translated or translated into an unstable protein. We described a syndromic form of deficiency of cPLA2a , characterised by recurrent GI ulcers and bleeding diathesis, associated with mild inherited deficiency of factor XI. Unlike other reported patients with cPLA2a deficiency, these patients had extremely low levels of platelet TxA2 biosynthesis.

    Full Text Available CONTEXT Upper gastrointestinal bleeding (UGIB is one of the commonest gastrointestinal emergencies encountered by clinicians. Peptic ulcers are the most common cause of UGIB. Endoscopy has become the preferred method for diagnosis in patients with acute UGIB. This study is done in a diagnostic upper gastrointestinal endoscopy (UGIE setup of a tertiary care hospital to ascertain the causes of UGIB prevalent in this part of our country which might differ from other studies. AIM To ascertain prevalent causes of UGIB in patients of this part of India admitted to a Govt. Tertiary Hospital with a provisional diagnosis of UGIB. METHOD One hundred consecutive patients with UGIB were subjected to UGIE to find out the aetiology. The clinical profile and endoscopic findings were analysed and compared with the data on UGIB from other studies. RESULTS The mean age of patients was 47.03 years with male: female ratio of 2.33:1. 58% of patients were first time bleeders. Majority of patients presented with melaena. Visualisation of active bleeding achieved to 85.7% when endoscopy was done within first 24 hrs. The commonest cause of UGIB was duodenal ulcer (DU which accounted for 41% cases. Gastric ulcer was responsible in 13% of cases. Portal hypertension was responsible for bleed in only 13%. Neoplasms accounted for 25% of cases. Other less common causes were erosive gastritis (3%, gastric polyp (3%, Mallory-Weiss tear (1%, and Dieulafoy’s lesion (1%. Among bleeding peptic ulcers, 27.8% of cases were classified as Forrest IIa and 20.4% in Forrest IIb & IIc each. Acid peptic disease was past history elicited in majority (33% followed by NSAID (26% and alcohol (26%. CONCLUSION The present study has diagnosed various causes of upper gastrointestinal bleeding in this part of country. The incidence of gastric carcinoma as a cause of upper gastrointestinal bleeding is significantly high compared to those in other studies. UGI endoscopy should be done in every case

    Renal cell carcinoma (RCC) has potential to present with distant metastasis several years after complete resection. The common sites of metastases include the lungs, bones, liver, renal fossa, and brain. RCCs metastasize rarely to the duodenum, and duodenal metastasis presenting with acute gastrointestinal bleed is infrequently reported in literature. We present a case of synchronous presentation of duodenal and azygoesophageal metastasis manifesting as acute upper gastrointestinal bleeding, four years after undergoing nephrectomy for RCC. The patient underwent further workup and was treated with radiation. The synchronous presentation is rare and stresses the importance of searching for recurrence of RCC in patients presenting with acute gastrointestinal bleeding. PMID:26640732

METHODS: Eighty-five (18 female, 67 male) patients admitted for acute gastrointestinal bleeding due to gastric or duodenal ulcer were included in the study. Upper endoscopy was performed and HPC or APC were chosen randomly to stop the bleeding. Initial hemostasis and rebleeding rates were primary and secondary end-points of the study. RESULTS: Initial hemostasis was achieved in 97.7% (42/43) and 81% (36/42) of the APC and HPC groups, respectively (P 0.05). CONCLUSION: APC is an effective hemostatic method in bleeding peptic ulcers. Larger multicenter trials are necessary to confirm these results.

    Modern direct-acting anticoagulants are rapidly replacing vitamin K antagonists (VKA) in the management of millions of patients worldwide who require anticoagulation. These drugs include agents that inhibit activated factor X (FXa) (such as apixaban and rivaroxaban) or thrombin (such as dabigatran), and are collectively known today as non-VKA oral anticoagulants (NOACs). Since bleeding is the most common and most dangerous side effect of long-term anticoagulation, and because NOACs have very different mechanisms of action and pharmacokinetics compared with VKA, physicians are naturally concerned about the lack of experience regarding frequency, management and outcome of NOAC-associated bleeding in daily care. This review appraises trial and registry (or "real-world") data pertaining to bleeding complications in patients taking NOACs and VKA and provides practical recommendations for the management of acute bleeding situations.

    Bleeding in the oral cavity, nose or ear are common events in the daily routine of ENT specialists. Apart from trivial cases that often get outpatient treatment, there are numerous cases of serious bleeding that require stationary treatment and if necessary, an operative or interventional therapy. In the following section the most frequent types of bleeding, their diagnosis and therapy will be explained. PMID:24285208

    Three case reports of cyclical rectal bleeding in endometriosis affecting rectum and sigmoid colon emphasize the close relationship between such cyclical bleeding and intestinal endometriosis. The cause of bleeding, however, is still unclear. The predilection of endometriotic deposits for the outer layers of the bowel wall suggests that mucosal involvement is not a prerequisite for rectal bleeding. The frequent absence of identifiable intramural haemorrhage casts doubt on the premise that intestinal endometriotic deposits 'menstruate'. The cause may simply be a transient tear in normal mucosa due to swelling of an underlying endometriotic deposit at the time of menstruation. PMID:2597100

    Mild inherited bleeding disorders are relatively common in the general population. Despite recent advances in diagnostic approaches, mild inherited bleeding disorders still pose a significant diagnostic challenge. Hemorrhagic diathesis can be caused by disorders in primary hemostasis (von Willebrand disease, inherited platelet function disorders), secondary hemostasis (hemophilia A and B, other (rare) coagulant factor deficiencies) and fibrinolysis, and in connective tissue or vascular formation. This review summarizes the currently available diagnostic methods for mild bleeding disorders and their pitfalls, from structured patient history to highly specialized laboratory diagnosis. A comprehensive framework for a diagnostic approach to mild inherited bleeding disorders is proposed. PMID:27208505

    Patients with diagnosed and undiagnosed chronic liver diseases experience one or more acute assaults of a hepatic nature and develop a downhill course of liver diseases, a condition regarded as acute-on-chronic liver failure (ACLF). It is a medical emergency, the prognosis of ACLF is extremely bad and considerable numbers of patients with ACLF die even after diagnosis and receiving conservative treatment. ACLF is characterized by jaundice, coagulopathy, ascites and encephalopathy. ACLF patients are very sick and associated with different hemodynamic profiles and have very high 3-month mortality. As these groups of patients have high baseline hepatic venous pressure gradients, the chances of variceal bleed are also high, and the impact is also greater in comparison to stable cirrhosis; however, evidence is lacking to substantiate such effects. The aim of this review is to discuss the natural course of variceal bleeding in ACLF patients and to develop insights into the management of variceal bleeding in ACLF.

    GI-cat framework implements a distributed catalog service supporting different international standards and interoperability arrangements in use by the geoscientific community. The distribution functionality in conjunction with the mediation functionality allows to seamlessly query remote heterogeneous data sources, including OGC Web Services - e.e. OGC CSW, WCS, WFS and WMS, community standards such as UNIDATA THREDDS/OPeNDAP, SeaDataNet CDI (Common Data Index), GBIF (Global Biodiversity Information Facility) services and OpenSearch engines. In the GI-cat modular architecture a distributor component carry out the distribution functionality by query delegation to the mediator components (one for each different data source). Each of these mediator components is able to query a specific data source and convert back the results by mapping of the foreign data model to the GI-cat internal one, based on ISO 19139. In order to cope with deployment scenarios in which local data is expected, an harvesting approach has been experimented. The new strategy comes in addition to the consolidated distributed approach, allowing the user to switch between a remote and a local search at will for each federated resource; this extends GI-cat configuration possibilities. The harvesting strategy is designed in GI-cat by the use at the core of a local cache component, implemented as a native XML database and based on eXist. The different heterogeneous sources are queried for the bulk of available data; this data is then injected into the cache component after being converted to the GI-cat data model. The query and conversion steps are performed by the mediator components that were are part of the GI-cat framework. Afterward each new query can be exercised against local data that have been stored in the cache component. Considering both advantages and shortcomings that affect harvesting and query distribution approaches, it comes out that a user driven tuning is required to take the best

    Background: Despite lack of evidence supporting the use of fecal occult blood test (FOBT) in the acute hospital setting, FOBT is commonly used in the inpatient setting for reasons other than colorectal cancer (CRC) screening. Aims: To evaluate practice trends in utilizing FOBT on inpatients and its impact on affecting clinical management and outcomes. Materials and Methods: A cross-sectional study of consecutive adult patients undergoing FOBT from January 1, 2011 to December 31, 2011 during an acute medical admission at a large urban safety net hospital was performed. Indications for FOBT, and the impact of FOBT results on endoscopic procedures performed and clinical outcomes were assessed. The number of inpatient endoscopic procedures before and after discontinuing inpatient FOBT was also assessed. Results: A total of 207 inpatient FOBTs were performed in 2011. The most common reason cited for FOBT was anemia (36%, n = 74) followed by gastrointestinal (GI) bleeding (27%, n = 55). Interestingly, 23% (n = 47) of the patients undergoing inpatient FOBT had overt GI bleeding. As expected, patients with positive FOBT were significantly more likely to undergo endoscopic examinations (P < 0.01). After discontinuing the availability of inpatient FOBT, patients were less likely to undergo endoscopic examinations [odds ratio (OR) 0.80, 95% confidence interval (CI) 0.75-0.85]. Conclusion: Inappropriate utilization of FOBT in the inpatient setting is common, even when the indication does not support its use. Setting limitations on inpatient FOBT may reduce the inappropriate utilization of inpatient FOBT. Quality improvement initiatives are needed to educate clinicians on the appropriate use of FOBT, which is primarily for average risk CRC screening. PMID:27089107

    2010-01-01

    Full Text Available Postmenopausal bleeding (PMB is a common clinical problem. Patients with PMB have 10%–15% chance of having endometrial carcinoma and therefore the diagnostic workup is aimed at excluding malignancy. Patient characteristics can alter the probability of having endometrial carcinoma in patients with PMB; in certain groups of patients the incidence has been reported to be as high as 29%. Transvaginal sonography (TVS is used as a first step in the diagnostic workup, but different authors have come to different conclusions assessing the accuracy of TVS for excluding endometrial carcinoma. Diagnostic procedures obtaining material for histological assessment (e.g., dilatation and curettage, hysteroscopy, and endometrial biopsy can be more accurate but are also more invasive. The best diagnostic strategy for diagnosing endometrial carcinoma in patients with PMB still remains controversial. Future research should be focussed on achieving a higher accuracy of different diagnostic strategies.

  17. Obstetric management of adolescents with bleeding disorders.

    Adolescents with bleeding disorders who become pregnant must contend with the dual challenges of their bleeding disorder and their pregnancy. Adolescents are more likely to terminate a pregnancy than adult women, and when they do carry a pregnancy, they are more likely to deliver prematurely. Otherwise, they are at risk for the same complications that adult women with bleeding disorders experience, particularly bleeding complications postpartum. Since one half to two thirds of adolescent pregnancies are unplanned, issues related to reproduction should be addressed during routine visits with the pediatrician, hematologist or gynecologist. Girls who are at risk of being carriers for hemophilia A and B, severe von Willebrand disease, and other severe bleeding disorders should have their bleeding disorder status determined before they become pregnant. During pregnancy, a plan should be established to ensure that both mother and fetus deliver safely. Young women at risk for severe bleeding or at risk of having a severely affected infant should be referred for prenatal care and delivery to a center where, in addition to specialists in high-risk obstetrics, there is a hemophilia treatment center or a hematologist with expertise in hemostasis. Prior to delivery or any invasive procedures, young women at risk for severe bleeding should receive prophylaxis. Since administration of desmopressin may result in hyponatremia, whenever available, virally inactivated or recombinant clotting factor concentrates should be used for replacement as opposed to fresh frozen plasma or cryoprecipitate.

    AIM: Anaemia caused by acute upper gastrointestinal bleeding is treated with blood transfusion or iron, but patients usually face a two-month recovery period from posthaemorrhage anaemia. This prospective, randomised, open,pilot study was designed to investigate whether recombinant human erythropoietin (Epoetin) therapy accelerate haematocrit increase in the post-bleeding recovery period.METHODS: We studied hospitalised patients admitted because of acute ulcer bleeding or haemorrhagic gastritis,who had a haematocrit of 27-33% and did not receive blood transfusions. One day after the endoscopic confirmation of cessation of bleeding, they were randomised either to erythropoietin (20 000 IU Epoetin alfa subcutaneously, on days 0, 4 and 6) plus iron (100 mg im, on days 1- 6, (G1) or iron only (G2). Haematocrit was measured on days 0, 6, 14,30, 45, and 60, respectively.RESULTS: One patient from G1 and two from G2 were lost to follow-up. Therefore, 14 and 13 patients from G1 and G2respectively were analysed. Demographic characteristics, serum iron, ferritin, total iron binding capacity, reticulocytes, and haematocrit were not significantly different at entry to the study.Median reticulocyte counts were significantly different between groups on day six (G1: 4.0, 3.0-6.4 vsG2: 3.5, 2.1-4.4%,P=0.03) and median haematocrit on day fourteen [G1: 35.9,30.7-41.0 vsG2: 32.5, 29.5-37.0% (median, range), P=0.04].CONCLUSION: Erythropoietin administration significantly accelerates correction of anemia after acute ulcer bleeding.The haematocrit gain is equivalent to one unit of transfused blood two weeks after the bleeding episode.

  6. CoGI: Towards Compressing Genomes as an Image.

    2015-01-01

    Genomic science is now facing an explosive increase of data thanks to the fast development of sequencing technology. This situation poses serious challenges to genomic data storage and transferring. It is desirable to compress data to reduce storage and transferring cost, and thus to boost data distribution and utilization efficiency. Up to now, a number of algorithms / tools have been developed for compressing genomic sequences. Unlike the existing algorithms, most of which treat genomes as one-dimensional text strings and compress them based on dictionaries or probability models, this paper proposes a novel approach called CoGI (the abbreviation of Compressing Genomes as an Image) for genome compression, which transforms the genomic sequences to a two-dimensional binary image (or bitmap), then applies a rectangular partition coding algorithm to compress the binary image. CoGI can be used as either a reference-based compressor or a reference-free compressor. For the former, we develop two entropy-based algorithms to select a proper reference genome. Performance evaluation is conducted on various genomes. Experimental results show that the reference-based CoGI significantly outperforms two state-of-the-art reference-based genome compressors GReEn and RLZ-opt in both compression ratio and compression efficiency. It also achieves comparable compression ratio but two orders of magnitude higher compression efficiency in comparison with XM--one state-of-the-art reference-free genome compressor. Furthermore, our approach performs much better than Gzip--a general-purpose and widely-used compressor, in both compression speed and compression ratio. So, CoGI can serve as an effective and practical genome compressor. The source code and other related documents of CoGI are available at: http://admis.fudan.edu.cn/projects/cogi.htm. PMID:26671800

    We wanted to assess the usefulness of rotational angiography after endoscopic marking with a metallic clip in upper gastrointestinal bleeding patients with no extravasation of contrast medium on conventional angiography. In 16 patients (mean age, 59.4 years) with acute bleeding ulcers (13 gastric ulcers, 2 duodenal ulcers, 1 malignant ulcer), a metallic clip was placed via gastroscopy and this had been preceded by routine endoscopic treatment. The metallic clip was placed in the fibrous edge of the ulcer adjacent to the bleeding point. All patients had negative results from their angiographic studies. To localize the bleeding focus, rotational angiography and high pressure angiography as close as possible to the clip were used. Of the 16 patients, seven (44%) had positive results after high pressure angiography as close as possible to the clip and they underwent transcatheter arterial embolization (TAE) with microcoils. Nine patients without extravasation of contrast medium underwent TAE with microcoils as close as possible to the clip. The bleeding was stopped initially in all patients after treatment of the feeding artery. Two patients experienced a repeat episode of bleeding two days later. Of the two patients, one had subtle oozing from the ulcer margin and that patient underwent endoscopic treatment. One patient with malignant ulcer died due to disseminated intravascular coagulation one month after embolization. Complete clinical success was achieved in 14 of 16 (88%) patients. Delayed bleeding or major/minor complications were not noted. Rotational angiography after marking with a metallic clip helps to localize accurately the bleeding focus and thus to embolize the vessel correctly.

    Full Text Available Background/Aim. Data about bleeding complicating primary percutaneous coronary intervention (PCI are more frequently obtained from randomized clinical trials on patients with acute coronary syndromes (ACS, but less frequently from surveys or registries on patients with STelevation myocardial infarction (STEMI. The aim of this study was to investigate the incidence, predictors and prognostic impact of in-hospital major bleeding in the population of unselected real-world patients with acute STEMI undergoing primary PCI. Methods. All consecutive patients presenting with STEMI who underwent primary PCI at a single large tertiary healthcare center between January 2005 and July 2009, were studied. Major bleeding was defined according to the Global Use of Strategies to Open Occluded Coronary Arteries (GUSTO study criteria. We examined the association between in-hospital major bleeding and death or major adverse cardiac events (MACE in patients treated with PCI. The primary outcomes were in-hospital and 6-month mortality and MACE. Results. Of the 770 STEMI patients treated with primary PCI, in-hospital major bleeding occurred in 32 (4.2% patients. Independent predictors of major bleeding were advanced age (≥ 65 years, female gender, baseline anemia and elevated white blood cell (WBC count and signs of congestive heart failure at admission (Killip class II-IV. In-hospital and 6-month mortality and MACE rates were more than 2.5-fold-higher in patients who developed major bleeding compared with those who did not. Major bleeding was a predictor of 6- month MACE, independent of a few risk factors (previous MI, previous PCI, diabetes mellitus and hypertension; (OR = 3.02; 95% CI for OR 1.20-7.61; p = 0.019, but was not a true independent predictor of MACE and mortality in the fully adjusted models. Conclusion: Patients of advanced age, female gender, with baseline anemia and elevated WBC count and those with Killip class II-IV at presentation are at

    2014-11-25

    A compressor bleed cooling fluid feed system for a turbine engine for directing cooling fluids from a compressor to a turbine airfoil cooling system to supply cooling fluids to one or more airfoils of a rotor assembly is disclosed. The compressor bleed cooling fluid feed system may enable cooling fluids to be exhausted from a compressor exhaust plenum through a downstream compressor bleed collection chamber and into the turbine airfoil cooling system. As such, the suction created in the compressor exhaust plenum mitigates boundary layer growth along the inner surface while providing flow of cooling fluids to the turbine airfoils.

    Molecular genetic analysis of inherited bleeding disorders has been practised for over 30 years. Technological changes have enabled advances, from analyses using extragenic linked markers to next-generation DNA sequencing and microarray analysis. Two approaches for genetic analysis are described, each suiting their environment. The Christian Medical Centre in Vellore, India, uses conformation-sensitive gel electrophoresis mutation screening of multiplexed PCR products to identify candidate mutations, followed by Sanger sequencing confirmation of variants identified. Specific analyses for F8 intron 1 and 22 inversions are also undertaken. The MyLifeOurFuture US project between the American Thrombosis and Hemostasis Network, the National Hemophilia Foundation, Bloodworks Northwest and Biogen uses molecular inversion probes (MIP) to capture target exons, splice sites plus 5' and 3' sequences and to detect F8 intron 1 and 22 inversions. This allows screening for all F8 and F9 variants in one sequencing run of multiple samples (196 or 392). Sequence variants identified are subsequently confirmed by a diagnostic laboratory. After having identified variants in genes of interest through these processes, a systematic procedure determining their likely pathogenicity should be applied. Several scientific societies have prepared guidelines. Systematic analysis of the available evidence facilitates reproducible scoring of likely pathogenicity. Documentation of frequency in population databases of variant prevalence and in locus-specific mutation databases can provide initial information on likely pathogenicity. Whereas null mutations are often pathogenic, missense and splice site variants often require in silico analyses to predict likely pathogenicity and using an accepted suite of tools can help standardize their documentation.

Specific analyses for F8 intron 1 and 22 inversions are also undertaken. The MyLifeOurFuture US project between the American Thrombosis and Hemostasis Network, the National Hemophilia Foundation, Bloodworks Northwest and Biogen uses molecular inversion probes (MIP) to capture target exons, splice sites plus 5' and 3' sequences and to detect F8 intron 1 and 22 inversions. This allows screening for all F8 and F9 variants in one sequencing run of multiple samples (196 or 392). Sequence variants identified are subsequently confirmed by a diagnostic laboratory. After having identified variants in genes of interest through these processes, a systematic procedure determining their likely pathogenicity should be applied. Several scientific societies have prepared guidelines. Systematic analysis of the available evidence facilitates reproducible scoring of likely pathogenicity. Documentation of frequency in population databases of variant prevalence and in locus-specific mutation databases can provide initial information on likely pathogenicity. Whereas null mutations are often pathogenic, missense and splice site variants often require in silico analyses to predict likely pathogenicity and using an accepted suite of tools can help standardize their documentation.

    2012-03-01

    This guideline presents recommendations for the step-wise management of patients with overt upper gastrointestinal bleeding. Hemodynamic status is first assessed, and resuscitation initiated as needed. Patients are risk-stratified based on features such as hemodynamic status, comorbidities, age, and laboratory tests. Pre-endoscopic erythromycin is considered to increase diagnostic yield at first endoscopy. Pre-endoscopic proton pump inhibitor (PPI) may be considered to decrease the need for endoscopic therapy but does not improve clinical outcomes. Upper endoscopy is generally performed within 24h. The endoscopic features of ulcers direct further management. Patients with active bleeding or non-bleeding visible vessels receive endoscopic therapy (e.g., bipolar electrocoagulation, heater probe, sclerosant, clips) and those with an adherent clot may receive endoscopic therapy; these patients then receive intravenous PPI with a bolus followed by continuous infusion. Patients with flat spots or clean-based ulcers do not require endoscopic therapy or intensive PPI therapy. Recurrent bleeding after endoscopic therapy is treated with a second endoscopic treatment; if bleeding persists or recurs, treatment with surgery or interventional radiology is undertaken. Prevention of recurrent bleeding is based on the etiology of the bleeding ulcer. H. pylori is eradicated and after cure is documented anti-ulcer therapy is generally not given. Nonsteroidal anti-inflammatory drugs (NSAIDs) are stopped; if they must be resumed low-dose COX-2-selective NSAID plus PPI is used. Patients with established cardiovascular disease who require aspirin should start PPI and generally re-institute aspirin soon after bleeding ceases (within 7 days and ideally 1-3 days). Patients with idiopathic ulcers receive long-term anti-ulcer therapy. PMID:22310222

    2014-01-01

    Full Text Available Asymptomatic large hiatal hernias may lead to iron deficiency anemia due to occult and massive bleeding from linear gastric erosions or ulcers on the mucosal folds at the level of the diaphragm called the Cameron lesions. The diagnosis is usually made during upper gastrointestinal system endoscopies. Current therapy includes the medication with proton pump inhibitors in combination with oral iron supplements and in some cases surgical reconstruction of hiatal hernia with fundoplication. We present a case of a 78-year-old woman who was admitted to the outpatient clinic with the diagnosis of iron deficiency anemia without signs of acute gastrointestinal bleeding. She was treated with medication and her follow-up gastroscopy showed a total cure. She is asymptomatic for two years after treatment with proton pump inhibitors and iron supplements. Cameron lesions should be kept in mind as an unusual cause of iron deficiency anemia due to gastrointestinal bleeding

    Peptic ulcers are an extremely common condition, usually occurring in the stomach and proximal duodenum. However, cases of peptic ulcers accompanied with multiple complications are extremely rare and hard to treat. The present case reinforces the requirement for the early recognition and correct treatment of peptic ulcers accompanied with multiple complications. A 67-year-old man presented with recurrent abdominal pain, fever and melena. The laboratory results showed anemia (hemoglobin 62 g/l) and hypoproteinemia (23 g/l). Abdominal imaging examinations revealed stones in the gallbladder and right liver, with air in the dilated intrahepatic and extrahepatic bile ducts. Endoscopic retrograde cholangiopancreatography failed due to a deformed pylorus. The patient was finally diagnosed with peptic ulcers accompanied with gastrointestinal (GI) bleeding, pylorus obstruction and cholangitis secondary to a choledochoduodenal fistula during an emergency pancreatoduodenectomy, which was performed due to a massive hemorrhage of the GI tract. The patient recovered well after the surgery. PMID:26870237

    Many prevalent practices and guidelines related to Gastrointestinal endoscopy and procedural sedation are at odds with the widely available scientific-physiological and clinical outcome data. In many institutions, strict policy of pre-procedural extended fasting is still rigorously enforced, despite no evidence of increased incidence of aspiration after recent oral intake prior to sedation. Supplemental oxygen administration in the setting of GI procedural sedation has been increasingly adopted as reported in the medical journals, despite clear evidence that supplemental oxygen blunts the usefulness of pulse oximetry in timely detection of sedation induced hypoventilation, leading to increased number of adverse cardiopulmonary outcomes. Use of Propofol by Gastroenterologist-Nurse team is erroneously considered dangerous and often prohibited in various institutions, at the same time worldwide reports of remarkable safety and patient satisfaction continue to be published, dating back more than a decade.

Advances in the technology often are not incorporated in a timely manner in guidelines or clinical practices, e.g., Capsule endoscopy or electrocautery during GI procedures do not interfere with proper functioning of the current pacemakers or defibrillators. Orthopedic surgeons have continued to recommend prophylactic antibiotics for joint replacement patientsprior to GI procedures, without any evidence of need. These myths are explored for a succint review to prompt a change in clinical practices and institutional policies.

  8. Imaging and PET-CT evaluation of Gi tract cancers

    International Nuclear Information System (INIS)

    Imaging plays a pivotal role in the management of G.I. tract cancers for diagnosis, characterization, locoregional staging, metastatic work-up and follow-up during and after curative or palliative treatment. The imaging protocols should be optimized and reproducible because of their impact on therapy. Thoracic, abdominal and pelvic CT is the cornerstone of the imaging work-up, optimized and reproducible because of their impact on therapy. Thoracic, abdominal and pelvic CT is the cornerstone of the imaging work-up, optimized and tailored to the specific G.I. segment involved, requiring good G.I. tract distension. Image interpretation of native axial and reformatted multiplanar images is routinely performed. In specific cases, additional targeted imaging with the US or MRI or whole body imaging with PET/CT or MRI may be valuable. PET/CT is a complement to morphological imaging. PET allows detection of lesions otherwise undetected on morphological imaging, usually due to poor contrast with surrounding tissues, and characterization of known lesions. PET/CT is best used as an integral part of a comprehensive imaging work-up. Radiologist and nuclear medicine specialists provide complementary information. each must be familiar with the clinical questions at hand and related stakes, and advantages and limitations of each modality to optimize treatment as part of a multidisciplinary management approach.

    Endoscopists seek to conduct more aggressive surgical procedures that surpass the limitations of existing endoscopic procedures. Endoscopic pancreatic necrosectomy and natural orifice transluminal endoscopic surgery (NOTES) are typical examples of this new trend; both are performed through the gastrointestinal wall without a skin incision. Endoscopic necrosectomy is effective for managing organized pancreatic necrosis and abscesses. The necrotic tissues are removed endoscopically by directly entering the cavity of the organized pancreatic necrosis. NOTES is a possible advance over surgical intervention, as it is a less invasive, more cosmetic, and effective procedure. There are various approaches, including the esophagus, stomach, colon, and vagina; Various procedures are possible using NOTES, such as cholecystectomy, appendectomy, full-thickness stomach resection, splenectomy, gastrointestinal (GI) anastomosis, and peritoneoscopy. The requirements for NOTES include high proficiency in endoscopic techniques, including knowledge of various devices, anatomy, and surgical procedures. Since most GI endoscopists have no surgical background, to increase the usage of NOTES, GI endoscopists should form and lead teams that include various specialists. We believe that endoscopic necrosectomy and NOTES represent a major shift in the treatment paradigm because physicians can treat beyond the gastrointestinal wall and endoscopic procedures will replace surgical treatment.

    Full Text Available The aim of this study was to investigate the effect of preemptive pantoprazole infusion on early endoscopic findings in patients with acute ulcer bleeding. Records of 333 patients admitted with acute ulcer bleeding were analyzed. Ulcer bleeders were given either 80 mg bolus of pantoprazole followed by continuous infusion of 8 mg per hour or saline infusion until endoscopy. In 93 patients saline infusion whereas in 240 patients bolus plus infusion of pantoprazole was administrated with mean (±SD durations of 5.45±12.9 hours and 6.9±13.2 hours, respectively (P=0.29. Actively bleeding ulcers were detected in 46/240 (19.2% of cases in the pantoprazole group as compared with 23/93 (24.7% in the saline infusion group (P=0.26. Different durations of pantoprazole infusion (0–4 hours, >4 hours, and >6 hours had no significant effect on endoscopic and clinical outcome parameters in duodenal ulcer bleeders. Gastric ulcer bleeders on pantoprazole infusion longer than 4 and 6 hours before endoscopy had actively bleeding ulcers in 4.3% and 5% compared to the 19.5% active bleeding rate in the saline group (P=0.02 and P=0.04. Preemptive infusion of high-dose pantoprazole longer than 4 hours before endoscopy decreased the ratio of active bleeding only in gastric but not in duodenal ulcer patients.

    Directory of Open Access Journals (Sweden)

    Pedro Monsanto

    2012-04-01

    Full Text Available Background: in 21st century, endoscopic study of the small intestine has undergone a revolution with capsule endoscopy and balloon-assisted enteroscopy. The difficulties and morbidity associated with intraoperative enteroscopy, the gold-standard in the 20th century, made this technique to be relegated to a second level. Aims: evaluate the actual role and assess the diagnostic and therapeutic value of intraoperative enteroscopy in patients with obscure gastrointestinal bleeding. Patients and methods: we conducted a retrospective study of 19 patients (11 males; mean age: 66.5 ± 15.3 years submitted to 21 IOE procedures for obscure GI bleeding. Capsule endoscopy and double balloon enteroscopy had been performed in 10 and 5 patients, respectively. Results: with intraoperative enteroscopy a small bowel bleeding lesion was identified in 79% of patients and a gastrointestinal bleed-ing lesion in 94%. Small bowel findings included: angiodysplasia (n = 6, ulcers (n = 4, small bowel Dieulafoy's lesion (n = 2, bleed-ing from anastomotic vessels (n = 1, multiple cavernous hemangiomas (n = 1 and bleeding ectopic jejunal varices (n = 1. Agreement between capsule endoscopy and intraoperative enteroscopy was 70%. Endoscopic and/or surgical treatment was used in 77.8% of the patients with a positive finding on intraoperative enteroscopy, with a rebleeding rate of 21.4% in a mean 21-month follow-up period. Procedure-related mortality and postoperative complications have been 5 and 21%, respectively. Conclusions: intraoperative enteroscopy remains a valuable tool in selected patients with obscure GI bleeding, achieving a high diagnostic yield and allowing an endoscopic and/or surgical treatment in most of them. However, as an invasive procedure with relevant mortality and morbidity, a precise indication for its use is indispensable.

  14. Octreotide in the Control of Post-Sclerotherapy Bleeding from Oesophageal Varices, Ulcers and Oesophagitis

    Directory of Open Access Journals (Sweden)

    Spencer A. Jenkins

    1996-01-01

    Full Text Available Bleeding from oesophageal varices, oesophageal ulcers or oesophagitis is occasionally massive and difficult to control. Octreotide, a synthetic analogue of somatostin lowers portal pressure and collateral blood flow including that through varices, increases lower oesophageal sphincter pressure, and inhibits the gastric secretion of acid as well as pepsin. Our current experience suggests it is effective in controlling acute variceal haemorrhage. Therefore we have examined the efficacy of octreotide in the control of postsclerotherapy bleeding from oesophageal varices, oesophageal ulcers and oesophagitis. During the study period 77 patients experienced a significant gastrointestinal bleed (blood pressure 100 beats per min or the need to transfuse 2 or more units of blood to restore the haemoglobin level following injection sclerotherapy of oesophageal varices. The source of bleeding was varices in 42 patients, oesophageal ulcers in 31 and oesophagitis in 4. All patients received a continuous intravenous infusion of octreotide (50 μg/h for between 40–140h. If bleeding was not controlled in the first 12h after commencing octreotide hourly bolus doses (50 μg for 24h were superimposed on the continuous infusion. Haemorrhage was successfully controlled by an infusion of octreotide in 38 of the 42 patients with bleeding from varices, in 30 of 31 patients with oesophageal ulceration, and all patients with oesophagitis. In the 1 patient with persistent bleeding from oesophageal ulceration and in 2 of the 4 with continued haemorrhage from varices, haemostasis was achieved by hourly boluses of 50 μg octreotide for 24h in addition to the continuous infusion. No major complications were associated with octreotide administration. The results of this study clearly indicate that octreotide is a safe and effective treatment for the control of severe haemorrhage after technically successful injection sclerotherapy.

    Mid-gastrointestinal bleeding is defined as a bleeding of the small bowel and is the most common indication for small bowel endoscopy. Intraoperative enteroscopy has been regarded as gold standard for a long time. With the introduction of different endoscopy techniques, they play now the central role, whereas intraoperative enteroscopy has become a reserve method for selected patients. Actually, there are, beside capsule endoscopy, five non-surgical, flexible enteroscopy techniques available. In Germany and Europe balloon-assisted enteroscopy (double balloon and single balloon enteroscopy) is mainly used. Double balloon enteroscopy (DBE) is the "oldest" flexible enteroscopy technique and has become established throughout the world for diagnostic and therapeutic examinations of the small bowel. The majority of the studies have been performed with DBE and it provides the highest rate of complete enteroscopy. Nevertheless, technical improvements to make enteroscopy easier and faster are still required. In patients with chronic MGI or problematic situations capsule endoscopy is an ideal screening option. In case of acute MGI the flexible enteroscopy techniques should be preferred because of the high diagnostic yield combined with the possibility of endoscopic therapeutic interventions. In difficult cases with unsuccessful enteroscopy, CT angiography and conventional angiography with the option of embolisation had proved their value.

    Acute upper gastrointestinal bleeding is a rare, but serious complication of gastric bypass surgery. The inaccessibility of the excluded stomach restrains postoperative examination and treatment of the gastric remnant and duodenum, and represents a major challenge, especially in the emergency setting. A 59-year-old patient with previous history of peptic ulcer disease had an upper gastrointestinal bleeding from a duodenal ulcer two years after having a gastric bypass procedure for morbid obesity. After negative upper endoscopy finding, he was urgently evaluated for gastrointestinal bleeding. At emergency laparotomy, the bleeding duodenal ulcer was identified by intraoperative endoscopy through gastrotomy. The patient recovered well after surgical hemostasis, excision of the duodenal ulcer and completion of the remnant gastrectomy. Every general practitioner, gastroenterologist and general surgeon should be aware of growing incidenceof bariatric operations and coherently possible complications after such procedures, which modify patient’s anatomy and physiology.

  20. What is happening? The evolving role of the blood bank in the management of the bleeding patient: The impact of TEG as an early diagnostic predictor for bleeding.

    Science.gov (United States)

    Espinosa, Aurora; Seghatchian, Jerard

    2014-12-01

    Despite recent advances in the understanding and treatment of coagulopathy, the management of the bleeding patient remains as a major challenge. Traditionally, the main task of the blood bank has been to guarantee the supply of high quality blood and blood components/products to the hospital. Decisions regarding the use of blood components have always been the clinicians' responsibility, with little active involvement of the transfusion service. In the last years, many hospitals have implemented the use of "acute transfusion packages" for massively bleeding patients and point-of-care (POC) instruments such as TEG and RoTEM for monitoring coagulation status in this patient group. This, in addition to the implementation of patient blood management programs in the hospitals, has led to an increasing involvement of transfusion medicine specialists in transfusion decision making, especially regarding strategies for monitoring and treatment of the massively bleeding patient. This new trend may contribute to a more optimal management and monitoring of the bleeding patient, as POC testing may be used as an early predictor for blood usage. The blood bank should optimise the use of POC testing to provide accurate information in a cost-effective way.

    /sup 99m/Tc labeled red blood cell scintigraphy was performed upon 39 patients with clinical evidence for acute lower gastrointestinal bleeding from an unknown source. Seventeen of 39 patients (44%) had a scan became positive 6 or more h after injection, consistent with intermittent bleeding, in 8 of 17 patients (47%). In the 11 patients in whom the bleeding site was definitely identified by arteriography, surgery, or colonoscopy, scintigraphy correctly localized the bleeding site in 10 of 11 patients (91%). Four of 11 patients (36%) had an active bleeding site identified by arteriography. Ten of 17 patients (58%) with a positive scan required either gelfoam embolization (4 patients) or surgery (6 patients) to control the bleeding, whereas only 1 of 22 patients (5%) required surgery when the scan was negative. Six deaths occurred in the scan-positive patients compared with no deaths in the scan-negative patients. None of the 8 patients who had arteriography and no active bleeding site by scintigraphy had arteriographically demonstrable active bleeding. Scintigraphy provides a reliable noninvasive test to screen patients in whom arteriography is being considered to localize active bleeding sites. If the arteriogram is negative, the scintigraphic findings alone may guide the surgical or arteriographic intervention. In addition, scintigraphy identifies two patient populations which have considerably different morbidity and mortality.

    The complications of pancreatitis, such as pseudocyst or abscesses, are well known to radiologists. Yet formation of a pseudoaneurysm of the short gastric artery is an uncommon complication of acute pancreatitis. It is also very rare for a psuedoaneurysm of the short gastric artery to cause splenic vein occlusion and the final result is gastric varices. We report here on a case that showed the dramatic effect of embolotherapy for a pseudoaneurysm of the short gastric artery that caused gastric variceal bleeding

    Occult gastrointestinal bleeding is not visible and may present with a positive fecal occult blood test or iron deficiency anemia. Obscure bleeding can be overt or occult, with no source identified despite an appropriate diagnostic workup. A stepwise approach to this evaluation after negative upper and lower endoscopy has been shown to be cost effective. This includes repeat endoscopies if warranted, followed by video capsule endoscopy (VCE) if no obstruction is present. If the VCE is positive then specific endoscopic intervention may be possible. If negative, patients may undergo either repeat testing or watchful waiting with iron supplements.

    We report the case of a woman of 84 years with a history of cardiac arrhythmia and hemorrhoids. She had multiple hospitalizations and transfusions for symptomatic iron deficiency anemia, endoscopic studies showed only small diverticula and colon polyps. He was later hospitalized with bloody stools red wines, upper endoscopy and colonoscopy showed gastritis, small colonic ulcers, colonic polyp and multiple diverticula. Readmitted with bleeding of obscure origin, on that occasion showed gastritis, antral erosions, small ulcers, colon polyps and colon ulcers in the process of healing, capsule endoscopy showed angiodysplasia in jejunum, anterograde enteroscopy detected some erythematous lesions in proximal jejunum without evidence of bleeding. Again hospitalized for melena and abdominal. PMID:22086325

    The department of internal medicine of the military hospital of Gabon managed 92 cases of upper gastrointestinal bleeding from April 2009 to November 2011. The frequency of these hemorrhages in the department was 8.2%; they occurred most often in adults aged 30-40 years and 50-60 years, and mainly men (74%). Erosive-ulcerative lesions (65.2%) were the leading causes of hemorrhage, followed by esophageal varices (15.2%). These results underline the importance of preventive measures for the control of this bleeding.

    2012-01-01

    Purpose: We compared acute and late genitourinary (GU) and gastrointestinal (GI) toxicities in prostate cancer patients treated with three different high-dose radiation techniques. Methods and Materials: A total of 1,903 patients with localized prostate cancer were treated with definitive RT at William Beaumont Hospital from 1992 to 2006: 22% with brachytherapy alone (BT), 55% with image-guided external beam (EB-IGRT), and 23% external beam with high-dose-rate brachytherapy boost (EBRT+HDR). Median dose with BT was 120 Gy for LDR and 38 Gy for HDR (9.5 Gy Multiplication-Sign 4). Median dose with EB-IGRT was 75.6 Gy (PTV) to prostate with or without seminal vesicles. For EBRT+HDR, the pelvis was treated to 46 Gy with an additional 19 Gy (9.5 Gy Multiplication-Sign 2) delivered via HDR. GI and GU toxicity was evaluated utilizing the NCI-CTC criteria (v.3.0). Median follow-up was 4.8 years. Results: The incidences of any acute {>=} Grade 2 GI or GU toxicities were 35%, 49%, and 55% for BT, EB-IGRT, and EBRT+HDR (p < 0.001). Any late GU toxicities {>=} Grade 2 were present in 22%, 21%, and 28% for BT, EB-IGRT, and EBRT+HDR (p = 0.01), respectively. Patients receiving EBRT+HDR had a higher incidence of urethral stricture and retention, whereas dysuria was most common in patients receiving BT. Any Grade {>=}2 late GI toxicities were 2%, 20%, and 9% for BT, EB-IGRT, and EBRT+HDR (p < 0.001). Differences were most pronounced for rectal bleeding, with 3-year rates of 0.9%, 20%, and 6% (p < 0.001) for BT, EB-IGRT, and EBRT+HDR respectively. Conclusions: Each of the three modern high-dose radiation techniques for localized prostate cancer offers a different toxicity profile. These data can help patients and physicians to make informed decisions regarding radiotherapy for prostate andenocarcinoma.

    A general overview is given of the causes of anemia with iron deficiency as well as the pathogenesis of anemia and the para-clinical diagnosis of anemia. Anemia with iron deficiency but without overt GI bleeding is associated with a risk of malignant disease of the gastrointestinal tract; upper...... gastrointestinal cancer is 1/7 as common as colon cancer. Benign gastrointestinal causes of anemia are iron malabsorption (atrophic gastritis, celiac disease, chronic inflammation, and bariatric surgery) and chronic blood loss due to gastrointestinal ulcerations. The following diagnostic strategy is recommended...... for unexplained anemia with iron deficiency: conduct serological celiac disease screening with transglutaminase antibody (IgA type) and IgA testing and perform bidirectional endoscopy (gastroscopy and colonoscopy). Bidirectional endoscopy is not required in premenopausal women

    Pectic ulcer is the most frequent cause of gastrointestinal bleeding. The homeostatic mechanism of bleeding, and coagulation, does not happen with values of pH less than 5,0. Therefore neutralization of gastric acidity (pH more than 5,0) is a recourse of control, improve the evolution and healing of peptic ulcer and to avoid a new bleeding. The aim of this study was to compare the results of treatment with omeprazole and ranitidine, in 57 patients admitted at emergency room of the Hospital Central de la Polic a Nacional del Per with endoscopic diagnosis of peptic ulcer, using Forrest classification. Patients received omeprazole 40 mg in bolus IV, followed by continuos infusion of 8 mg/hour for 72 hours (group A) or ranitidine 50 mg IV each 8 hours for 72 hours (group B). A new endoscopy was made 72 hours after admission demostrated a succesful therapy in both group. Bleeding stopped in 26/27 patients in group A (96,2%) and in 23/30 patients in group B (76,6%) (pomeprazole IV is more effective than ranitidine IV in the control of UGB because of peptic ulcer and provides a faster healing.

    Purpose: To report on the incidence, nature, and management of rectal toxicities following individual or combination brachytherapy following treatment for prostate cancer over a 17-year period. We also report the patient and treatment factors predisposing to acute ≥grade 2 proctitis. Methods and Materials: A total of 2752 patients were treated for prostate cancer between October 1990 and April 2007 with either low-dose-rate brachytherapy alone or in combination with androgen depletion therapy (ADT) or external beam radiation therapy (EBRT) and were followed for a median of 5.86 years (minimum 1.0 years; maximum 19.19 years). We investigated the 10-year incidence, nature, and treatment of acute and chronic rectal toxicities following BT. Using univariate, and multivariate analyses, we determined the treatment and comorbidity factors predisposing to rectal toxicities. We also outline the most common and effective management for these toxicities. Results: Actuarial risk of ≥grade 2 rectal bleeding was 6.4%, though notably only 0.9% of all patients required medical intervention to manage this toxicity. The majority of rectal bleeding episodes (72%) occurred within the first 3 years following placement of BT seeds. Of the 27 patients requiring management for their rectal bleeding, 18 underwent formalin treatment and nine underwent cauterization. Post-hoc univariate statistical analysis revealed that coronary artery disease (CAD), biologically effective dose, rectal volume receiving 100% of the prescription dose (RV100), and treatment modality predict the likelihood of grade ≥2 rectal bleeding. Only CAD, treatment type, and RV100 fit a Cox regression multivariate model. Conclusions: Low-dose-rate prostate brachytherapy is very well tolerated and rectal bleeding toxicities are either self-resolving or effectively managed by medical intervention. Treatment planning incorporating adjuvant ADT while minimizing RV100 has yielded the best toxicity-free survival following

    Gastrointestinal vascular malformations are responsible for 2-8% of all cases of bleeding and 30-40% of all obscure hemorrhages, being the most frequent cause of occult bleeding in older people. The aim of this review was to provide an up-to-date report about the use of octreotide in bleeding from both hereditary and acquired vascular malformations of the gastrointestinal tract. A systematic literature search was performed, using the keywords "gastrointestinal vascular malformation", "octreotide", "angiodysplasia", "portal hypertensive gastropathy", "gastric antral vascular ectasia", and "hereditary vascular malformations". The first line therapy of acute/chronic bleeding from digestive vascular malformations is endoscopy, followed by angiographic embolization and surgical resection when this is unsuccessful. In the setting of difficult-to-treat patients, octreotide has been proposed as an alternative therapeutic strategy. Studies reported in the literature show a high efficacy and safety of octreotide, but described only a small number of enrolled patients, heterogeneous therapeutic schedules and short-term follow-up, with the exception of acute bleeding from esophageal varices. As a consequence, the use of octreotide is not approved in this setting and it is currently still prescribed as an off-label drug. Studies in larger populations are needed to confirm the promising results observed in the small case series reports, so as to provide physicians with a treatment option for patients without available alternatives. Octreotide could also determine a strong decrease in the management costs of these clinical conditions, and especially, could dramatically reduce hospital admission costs. PMID:27595456

    Full Text Available Clinically significant bleeding is important for subsequent optimal case management in dengue patients, but most studies have focused on dengue severity as an outcome. Our study objective was to identify differences in admission parameters between patients who developed clinically significant bleeding and those that did not. We sought to develop a model for discriminating between these patients.We conducted a retrospective study of 4,383 adults aged >18 years who were hospitalized with dengue infection at Tan Tock Seng Hospital, Singapore from 2005 to 2008. Patients were divided into those with clinically significant bleeding (n = 188, and those without (n = 4,195. Demographic, clinical, and laboratory variables on admission were compared between groups to determine factors associated with clinically significant bleeding during hospitalization.On admission, female gender (p38°C (p38°C (aOR 1.81; 95% CI: 1.27-2.61, nausea/vomiting (aOR 1.39; 95% CI: 0.94-2.12, ANC (aOR 1.3; 95% CI: 1.15-1.46, ALC (aOR 0.4; 95% CI: 0.25-0.64, hematocrit percentage (aOR 0.96; 95% CI: 0.92-1.002 and platelet count (aOR 0.993; 95% CI: 0.988-0.998. At the cutoff of -3.919, the model achieved an AUC of 0.758 (sensitivity:0.87, specificity: 0.38, PPV: 0.06, NPV: 0.98.Clinical risk factors associated with clinically significant bleeding were identified. This model may be useful to complement clinical judgement in triaging adult dengue patients given the dynamic nature of acute dengue, particularly in pre-identifying those less likely to develop clinically significant bleeding.

    Full Text Available Background: Abnormal Uterine Bleeding (AUB is referred as bleeding outside of normal menstruation pattern and it is the most common gynecological problem for women of all ages. This study was evaluated the correlation of menstrual bleeding patterns and endometrial histopathological findings in perimenopausal women. Methods: This study was done on perimenopausal aged women presented with AUB for the last 6 months at a gynecology clinic of a tertiary medical center. Only the patients with isolated endometrial causes of AUB were selected for study. A total of 313 cases were included in the study. Abnormal bleeding patterns of the patients were recorded and endometrial sampling was performed to all women. AUB was classified as menorrhagia, metrorrhagia, menometrorrhagia, polymenorrhea, intermenstrual bleeding, and histopathological findings were classified as Proliferative Endometrium (PE, Secretory Endometrium (SE, Disordered Proliferative Pattern (DPP, Endometrial Polyp (EP, Chronic Endometritis (CE, Endometrial Hyperplasia (EH, and Endometrial Adenocarcinoma (CA. Results: The most common bleeding pattern was menorrhagia (45.0% and the most common histopathological finding was PE+SE (52.0% in our study. PE+SE and endometrial hyperplasia without atypia were found more common in menorrhagia group. The most histopathological findings were found PE+SE in menometrorrhagia and polymenorrhea group (P 0.05. Conclusions: We concluded that although menometrorrhagia and polymenorrhea were significantly more associated with PE+SE, intermenstrual bleeding was significantly more associated with EP and CE. It is noteworthy that endometrial hyperplasia without atypia is significantly higher in patients with menorrhagia which is the most common abnormal bleeding pattern in perimenopausal aged women.

    Four patients with spontaneous bleeding from the pancreas are described. Transpapillary bleeding is diagnosed endoscopically. Angiography can demonstrate the eroded vessel directly. Ultrasound, CT and ERCP demonstrate the underlying abnormality in the pancreas. Bleeding into a cyst produces characteristic echoes, or an increase in density. NMR is able to demonstrate pancreatitis and pancreatic pseudo-cysts. Early diagnosis is extremely important, since without appropriate surgery, pancreatic bleeding is frequently fatal. 7 figs.

    Full Text Available Muco-cutaneous bleeding is a common presenting feature of acute leukemias. Mucosal bleeding usually manifests as gum bleeding and/or epistaxis but may occur in any mucosal surface of the body. Hematuria as an isolated or main presenting feature of acute leukemia is rare. We describe two cases of acute leukemia, a 19 year old male with acute lymphoblastic leukemia and a 52 year old male with acute myeloid leukemia, both presenting with gross hematuria. There was no demonstrable leukemic infiltration of the urinary tract on imaging studies. Hematuria in these patients was likely to be due to occult leukemic infiltration of the urinary system, aggravated by thrombocytopenia, as it subsided after starting chemotherapy. Our cases highlight that hematuria should be remembered as a rare presenting feature of acute leukemia.

    The construction of the life-support system to perform space, moon base, Mars emigration is demanded. The space foods will play a very important role of life support on this occasion. Particularly, in environment of the microgravity, our metabolism becomes less than the face of the Earth. The management of the blood sugar level is very important. We need to eat the meal which will be rise in blood sugar level slowly. The barley which includes much water-soluble dietary fibers is helpful to make low GI space food. After eating 30% barley with unpolished rice, blood sugar level was rise slowly. The cooking process is very important to our body in thinking about digestion and absorption. Soft foods, long-heated foods and grind-foods are easy to digest. After eating these-foods, our blood sugar level will rise, easily. We introduce the space foods with 30% wheat that the blood sugar level is hard to rising.

    Introduction We report the first case of a patient who underwent simultaneous kidney and pancreas transplantation and who then suffered from repeated episodes of severe gastrointestinal bleeding over a period of seven years. Locating the site of gastrointestinal bleeding is a challenging task. This case illustrates that detection of an arterio-enteric fistula can be very difficult, especially in technically-challenging situations such as cases of severe intra-abdominal adhesions. It is important to consider the possibility of arterio-enteric fistulas in cases of intermittent bleeding episodes, especially in transplant patients. Case presentation A 40-year-old Caucasian man received a combined pancreas-kidney transplantation as a result of complications from diabetes mellitus type I. Thereafter, he suffered from intermittent clinically-relevant episodes of gastrointestinal bleeding. Repeat endoscopic, surgical, scintigraphic, and angiographic investigations during his episodes of acute bleeding could not locate the bleeding site. He finally died in hemorrhagic shock due to arterio-enteric bleeding at the kidney graft site, which was diagnosed post-mortem. Conclusions In accordance with the literature, we suggest considering the removal of any rejected transplant organs in situations where arterio-enteric fistulas seem likely but cannot be excluded by repeat conventional or computed tomography-angiographic methods. Arterio-enteric fistulas may intermittently bleed over many years. PMID:21059222

    2013-06-01

    Dabigatran etexilate is a competitive, direct thrombin inhibitor that works in the coagulation cascade to ultimately prevent thrombus formation. It is recommended by the 2012 American College of Chest Physicians evidence-based clinical practice guidelines as first-line therapy over vitamin k antagonists for long-term antithrombotic therapy in patients with paroxysmal or persistent nonrheumatic atrial fibrillation who are at intermediate to high risk of stroke and systemic embolism (grade 2B). However, serious postmarketing events involving life-threatening bleeding are emerging with no antidote for reversal of the anticoagulant effect being available for use. Potential reversal agents are being used in clinical practice with questionable efficacy and safety profiles. We report a case involving an 84-year-old male with acute kidney injury who developed life-threatening gastrointestinal and surgical site bleeding secondary to dabigatran accumulation. Use of the Naranjo probability scale indicated a probable cause between the bleeding event and dabigatran use. After discontinuation of drug therapy, fresh frozen plasma, recombinant coagulation factor VIIa, and cryoprecipitate were administered as potential reversal agents with negligible benefit. However, this patient appeared to slowly benefit with administration of continuous venovenous hemodialysis. Based upon our experience with this patient and literature review, the most effective treatment algorithm for dabigatran-associated bleeding may be to utilize hemodialysis initially. PMID:23160864

    2008-07-01

    Full Text Available Background: Conventional risk factors for coronary artery disease and myocardial infarction do not explain all of the clinical and epidemiological features of the disease. Periodontal disease is a common bacterial and destructive disorder of oral tissues. Many studies demonstrate close association between chronic periodontitis and development of generalized inflammation, vascular endothelial injury, and atherosclesis. Periodontal disease has been convincingly emerging as an important independent risk factor for ischemic heart disease. A case - control study was carried out to assess the prevalence of periodontitis in patients with Acute myocardial Infarction (AMI and evaluate the possible relationship between AMI and chronic periodontitis. Patients and Methods: A number of 160 patients, aged 35 to 70 years old, enrolled in the study. Eighty patients (43 men, 37 women were examined four days after hospitalization due to AMI. Control group consisted of 80 persons (38 men, 42 women with normal coronary angiography. The following periodontal parameters were examined: Plaque index (PI, gingiral index (GI, bleeding on probing (BOP, probing depth (PD, clinical attachment loss (CAL and number of sites with CAL.Results: The case, compared to control showed significantly worse results for some periodontal variables studied: The mean of PD and PD > 3 mm, CAL, and number of sites with CAL, had worse results compared to control despite similar oral hygiene and frequency of brushing. The confounding factors for the present study were found to be hypertension and diabetes. Conclusion: The association between periodontitis and acute myocardial infarction was significant after adjusting for conventional risk factors for AMI.

    Massive upper gastrointestinal bleeding due to malignancy is relatively uncommon and the duodenum is the least frequently involved site. Duodenal metastasis is rare in renal cell carcinoma (RCC) and early detection, especially in case of a solitary mass, helps in planning further therapy. We report a case of intractable upper gastrointestinal bleeding from metastatic RCC to the duodenum. The patient presented with melena and anemia, 13 years after nephrectomy for RCC. On esophagogastroduodenoscopy, a submucosal mass was noted in the duodenum, biopsies of which revealed metastatic RCC. In conclusion, metastasis from RCC should be considered in nephrectomized patients presenting with gastrointestinal symptoms and a complete evaluation, especially endoscopic examination followed by biopsy, is suggested.

Duodenal metastasis is rare in renal cell carcinoma (RCC and early detection, especially in case of a solitary mass, helps in planning further therapy. We report a case of intractable upper gastrointestinal bleeding from metastatic RCC to the duodenum. The patient presented with melena and anemia, 13 years after nephrectomy for RCC. On esophagogastroduodenoscopy, a submucosal mass was noted in the duodenum, biopsies of which revealed metastatic RCC. In conclusion, metastasis from RCC should be considered in nephrectomized patients presenting with gastrointestinal symptoms and a complete evaluation, especially endoscopic examination followed by biopsy, is suggested.

    Leeches are blood-sucking hermaphroditic parasites that attach to vertebrate hosts, bite through the skin, and suck out blood. When leeches feed, they secrete an anticoagulant (hirudin), which helps them get a full meal of blood. This is the first report of leech removal from external auditory canal. Previous leech involvement cases were explained in nasopharynx, larynx, pharynx, eye, and gastrointestinal tract. Prominent sign of all cases was active bleeding from the leech attachment site; t...

    Background and study aims: Gastrointestinal bleeding in children and adolescents accounts for up to 20 % of referrals to gastroenterologists. Detailed management guidelines exist for gastrointestinal bleeding in adults, but they do not encompass children and adolescents. The aim of this study was to assess gastrointestinal bleeding in pediatric patients and to determine an investigative management algorithm accounting for the specifics of children and adolescents. Patients and methods: Pediatric patients with gastrointestinal bleeding admitted to our endoscopy unit from 2001 to 2009 (n = 154) were identified. Retrospective statistical and neural network analysis was used to assess outcome and to determine an investigative management algorithm. Results: The source of bleeding could be identified in 81 % (n = 124/154). Gastrointestinal bleeding was predominantly lower gastrointestinal bleeding (66 %, n = 101); upper gastrointestinal bleeding was much less common (14 %, n = 21). Hematochezia was observed in 94 % of the patients with lower gastrointestinal bleeding (n = 95 of 101). Hematemesis (67 %, n = 14 of 21) and melena (48 %, n = 10 of 21) were associated with upper gastrointestinal bleeding. The sensitivity and specificity of a neural network to predict lower gastrointestinal bleeding were 98 % and 63.6 %, respectively and to predict upper gastrointestinal bleeding were 75 % and 96 % respectively. The sensitivity and specifity of hematochezia alone to predict lower gastrointestinal bleeding were 94.2 % and 85.7 %, respectively. The sensitivity and specificity for hematemesis and melena to predict upper gastrointestinal bleeding were 82.6 % and 94 %, respectively. We then developed an investigative management algorithm based on the presence of hematochezia and hematemesis or melena. Conclusions: Hematochezia should prompt colonoscopy and hematemesis or melena should prompt esophagogastroduodenoscopy. If no

    AIM To evaluate the efficacy of endoscopic hemoclip in the treatment of bleeding peptic ulcer.METHODS Totally, 40 patients with F1a and F1b hemorrhagic activity of peptic ulcers were enrolled in this uncontrolled prospective study for endoscopic hemoclip treatment. We used a newly developed rotatable clip-device for the application of hemoclip (MD850) to stop bleeding. Endoscopy was repeated if there was any sign or suspicion of rebleeding, and reclipping was performed if necessary and feasible.RESULTS Initial hemostatic rate by clipping was 95%, and rebleeding rate was only 8%.Ultimate hemostatic rates were 87%, 96%, and 93% in the F1a and F1b subgroups, and total cases, respectively. In patients with shock on admission, hemoclipping achieved ultimate hemostasis of 71% and 83% in F1a and F1b subgroups, respectively. Hemostasis reached 100% in patients without shock regardless of hemorrhagic activity being F1a or F1b. The average number of clips used per case was 3.0 (range 2- 5). Spurting bleeders required more clips on average than did oozing bleeders (3.4 versus 2.8 ). We observed no obvious complications, no tissue injury, or impairment of ulcer healing related to hemoclipping.CONCLUSION Endoscopic hemoclip placement is an effective and safe method. With the improvement of the clip and application device,the procedure has become easier and much more efficient. Endoscopic hemoclipping deserves further study in the treatment of bleeding peptic ulcers.

    The patient is an 82 year-old female with a history of osteoarthritis, hypothyroidism and anemia for 14 years (receiving blood transfusions). She was admited to our hospital with a nine months history of malaise, anorexia, fatigue and weakness, associated with intermitten episodes of abdominal pain. She was diagnosed anemia and occult blood positive stools. Physical examination revealed a patient in generally fair condition, obese, with mild edema of lower limbs, no changes in the evaluation of chest, cardiovascular, abdomen, etc. Laboratory data was unremarkable, except for iron deficiency anemia. The upper endoscopy showed duodenal ulcer scar, fundic polyposis and chronic gastritis. Colonoscopy revealed some diverticula, a small sessile polyp and internal hemorrhoids. The diagnosis of obscure gastrointestinal bleeding was made. The CT scan of the abdomen showed gallstones and fatty liver; a radiograph of intestinal transit detected a lesion apparently protruded intestinal loop for distal jejunum; enteroscopy was performed (with one team ball) anterograde and retrograde achieving assess distal jejunum and distal ileum without observing any injuries. The study of capsule endoscopy showed a polypoid tumor intestinal with evidence of having bleeding. Surgery detected the tumor in proximal ileum. The surgical specimen findings showed three tumors 0.7 mm, 10 mm and 15 mm on the proximal ileum. The microscopic examination revealed that these lesions were neuroendocrine tumors (carcinoid). The Ileal carcinoid tumor may rarely presented with obscure gastrointestinal bleeding. PMID:21544161

    Despite the worldwide prevalence of rare bleeding disorders (RBDs), knowledge of these conditions and their management is suboptimal; health care professionals often have little diagnostic and treatment experience with variable access to diagnostic modalities required for accurate identification. Therefore, patients often experience morbidity and mortality due to delayed diagnosis. As RBDs represent a small potential commercial market, few, if any, specific therapies exist for these conditions. As a result, affected individuals commonly face delayed diagnosis, incomplete laboratory evaluation, and limited treatment options. Standardization and customization of coagulation assays, full genome sequencing, and global clotting assays will significantly improve diagnosis of patients with RBDs. In addition, new therapeutic modalities, both recombinant and plasma derived, are emerging, at least in developed countries. Registries and clinical trials have demonstrated decreased bleeding and improved outcomes when patients are appropriately diagnosed and properly treated. Expansion and harmonization of international registries has been initiated to correlate genotype, laboratory, and clinical phenotypes including bleeding severity to improve the diagnosis and therapeutic approach. This review focuses on the latest advances in our understanding, diagnosis, and treatment of RBDs. PMID:25712993

    ños, variación de 7 meses a 18,9 años, en el periodo de 1998 a 2006, en un hospital terciario universitario. El diagnóstico de hipertensión portal fue establecido por ultrasonografía y la cirrosis fue confirmada por la histología y clasificada respecto a la gravedad por el escore Child-Pugh. RESULTADOS: Las causas de la hipertensión portal fueron obstrucción extrahepática de la vena porta en 11/17 casos (64,7% y cirrosis hepática en 6/17 (35,3%. El sangramiento fue controlado en 14/17 pacientes (82,3%. El tiempo de infusión de la droga necesario para control del sangramiento fue semejante entre cirróticos y no cirróticos, pero la caída en los niveles de hemoglobina, el volumen transfusional requerido y el tiempo de internación fueron superiores en los pacientes con cirrosis, aunque sin diferencia estadística. Esas mismas variables no se modificaron respecto a los dos distintos esquemas de infusión de la droga: con dosis de ataque o iniciando con dosis de mantenimiento. Fracaso terapéutico fue observado con mayor frecuencia entre los pacientes cirróticos (33,3%. Hiperglucemia fue el único efecto secundario detectado durante la infusión. CONCLUSIONES: La administración de octreotide en niños y adolescentes con sangramiento digestivo por hipertensión portal fue segura y efectiva en el control del sangramiento agudo, independiente de la causa de la hipertensión portal y del esquema de infusión.OBJECTIVE: To describe clinical data of children and adolescents with portal hypertension, during with and without liver cirrhosis, treated with octreotide during episodes of acute upper gastrointestinal bleeding. METHODS: Retrospective and descriptive study of 26 episodes of gastrointestinal bleeding in 17 patients (mean age: 8.6 years; range: seven months to 18.9 years assisted at a tertiary university hospital from 1996 to 2006.

  2. Bronchial artery embolization for therapy of pulmonary bleeding in patients with cystic fibrosis

    International Nuclear Information System (INIS)

    Introduction: Acute pulmonary emergencies in patient with cystic fibrosis (CF) can be found in cases of pneumothorax as well as hemoptysis. If the bleeding cannot be stopped by conservative methods, an embolization of the bronchial arteries should be done. Materials and Method: 11 patients were embolized using a combination of PVA particles and microcoils. Results: From January 1996 to June 2001 17 bronchial arteries in 11 patients were embolized. 7 patients suffered from chronical hemoptysis, 4 patients had an acute hemoptysis. In 4 patients both sides were embolized, in 3 patients only one side. The remaining 4 patients needed a second intervention, embolizing the other side. The primary embolizated bronchial artery was still closed in all 4 patients. In 1 patient the selective catheterization of a bronchial artery was not successful, thus the embolization could not be carried out. 1 patient died 5 days after the intervention due to a fulminant pneumonia (Pseudomonas aeruginosa) without recurrent bleeding. In two patients atypical branches from intercostal arteries feeding the bronchial arteries were detected and successfully embolized. All patients profited from the therapy, as bleeding could be stopped or at least be reduced. 3 patients suffered from back pain during or after intervention. There were no severe complications like neurological deficiencies or necroses. (orig.)

    Background. Endoscopy and occasionally X-ray studies are used to discover the focus of a gastrointestinal bleeding. Material and methods. We describe a case of severe gastrointestinal bleeding where these methods failed. Scintigraphy after labelling of erythrocytes with 99m technetium was performed in a continuos manner for 60 minutes. Scintigrams were also taken three, ten and 23 hours after the injection. Results. No bleeding was revealed after 60 minutes but two hours later a slight radioactivity was encountered in the right part of the abdomen and the later images localised the bleeding in the right colon. The bleeding ceased after right-sided hemicolectomy. Interpretation. Scintigraphy is of value in localisation of gastrointestinal bleeding and should be performed in a continuos manner until the bleeding focus is localised. Secretion of unbound technetium through the mucosa of the stomach and its presence in the urinary tract should be taken in account.

    This study evaluated the magnitude and distribution of acute gastrointestinal illness (GI) in Gálvez, Argentina, and assessed the outcome of a seven-day versus 30-day recall period in survey methodology. A cross-sectional population survey, with either a seven-day or a 30-day retrospective recall period, was conducted through door-to-door visits to randomly-selected residents during the ‘high’ and the ‘low’ seasons of GI in the community. Comparisons were made between the annual incidence rates obtained using the seven-day and the 30-day recall period. Using the 30-day recall period, the mean annual incidence rates was 0.43 (low season of GI) and 0.49 (high season of GI) episodes per person-year. Using the seven-day recall period, the mean annual incidence rate was 0.76 (low season of GI) and 2.66 (high season of GI) episodes per person-year. This study highlights the significant burden of GI in a South American community and confirms the importance of seasonality when investigating GI in the population. The findings suggest that a longer recall period may underestimate the burden of GI in retrospective population surveys of GI. PMID:20411678

    Glycoprotein D (gD) and glycoprotein I (gI) genes of bovine herpes virus 1 (BHV1) are contiguous genes with 141 bp region between the two open reading frames (ORFs). Expression of gD and gI from a bicistronic construct containing complete gD and gI gene has been reported either through internal ribosome entry site (IRES)-like element or through the scanning and leakage model (Mukhopadhyay 2000). We here show by computational and experimental means that gD is expressed solely as bicistronic transcript comprising gD and gI coding region in BHV1-infected cells. gI ORF was also shown to express separately. An IRES-like element was also predicted by IRES predicting software in the middle of the gD coding region; within that region a putative promoter was also identified by promoterscan. The intergenic region between the two ORF showed extensive secondary structure which brings the stop codon of gD very close to start codon of gI gene. gD gene transcript in BHV1-infected cells was solely bicistronic. gI transcript was also present in the BHV1-infected cells but in low copy number. The results indicate that gI is probably transcribed from its own transcript in BHV1-infected cells.

  7. The role of computerized tomography in the evaluation of gastrointestinal bleeding following negative or failed endoscopy: A review of current status

    2008-01-01

    Full Text Available Gastrointestinal bleeding remains an important cause for emergency hospital admission with a significant related morbidity and mortality. Bleeding may relate to the upper or lower gastrointestinal tracts and clinical history and examination may guide investigations to the more likely source of bleeding. The now widespread availability of endoscopic equipment has made a huge impact on the rapid identification of the bleeding source. However, there remains a large group of patients with negative or failed endoscopy, in whom additional techniques are required to identify the source of bleeding. In the past, catheter angiography and radionuclide red cell labeling techniques were the preferred ′next step′ modalities used to aid in identifying a bleeding source within the gastrointestinal tract. However, these techniques are time-consuming and of limited sensitivity and specificity. In addition, catheter angiography is a relatively invasive procedure. In recent years, computerized tomography (CT has undergone major technological advances in its speed, resolution, multiplanar techniques and angiographic abilities. It has allowed excellent visualization of the both the small and large bowel allowing precise anatomical visualization of many causes of gastrointestinal tract (GIT bleeding. In addition, recent advances in multiphasic imaging now allow direct visualization of bleeding into the bowel. In many centers CT has therefore become the ′next step′ technique in identifying a bleeding source within the GIT following negative or failed endoscopy in the acute setting. In this review article, we review the current literature and discuss the current status of CT as a modality in investigating the patient with GIT bleeding.

    The micro-systems used for in vivo physical inspection have many advantages over traditional methods. In order to aid diagnosis of gastrointestinal (GI) motility disorders, a capsule is developed for GI pressure and pH inspection. Localization of the capsule in GI tract with time is a necessary condition for subsequent data analysis and medical diagnosis. It is also a common problem facing all in vivo mobile micro-systems. An approach of segment localization by utilizing some key points along GI tract is proposed. A portable ultrasonic detecting device was designed for this purpose. Experiments under conditions similar to GI tract were carried out and the results proved the effectiveness and reliability of this method and the device.

  9. Spectrum of histopathological findings in postmenopausal bleeding

    International Nuclear Information System (INIS)

    To determine the frequencies of histopathological findings in endometrial and endocervical biopsy samples with clinical history of Postmenopausal Bleeding (PMB). Study Design: Descriptive cross-sectional study. Place and Duration of Study: Section of Histopathology, Department of Pathology and Laboratory Medicine, The Aga Khan University Hospital, Karachi, from February 2012 to January 2013. Methodology: A total of 157 consecutive endometrial and endocervical biopsy specimens with history of postmenopausal bleeding were included. After microscopic examination, frequencies of histological findings in different age groups were generated. Chi-square and independent sample t-tests were applied to see whether the difference was significant which was set at p < 0.05. Results: One hundred and twenty-one (77.1%) specimens showed benign pathologies while 36 (22.9%) were malignant. Endometrial polyp was seen in 67 (42.7%) cases followed by endometrial carcinomas in 25 (15.9%), endometrial hyperplasia in 21 (13.4%), cervical carcinoma in 12 (7.6%) and cervical polyps in 9 (5.7%) cases. Ahighly significant increase in the percentage of malignant and pre-malignant lesions was seen with increasing age group (p < 0.001). Mean age of patients with type-2 endometrial carcinoma was higher than type-1 endometrial carcinoma but statistical significance was not observed (70.2 ± 6.5 vs. 61.8 ± 9.1 years respectively, p=0.069). Conclusion: Although benign pathologies were more common in postmenopausal bleeding but the collective proportion of endometrial and cervical malignancies and pre-malignant conditions was quite high. Therefore, PMB should be urgently evaluated for cause and early commencement of treatment. (author)

  11. Devil's claw root: ulcers and gastrointestinal bleeding?

    Science.gov (United States)

    2013-12-01

    Harpagophytum procumbens, or devil's claw, is an African plant whose root is used to relieve minor joint symptoms. Several cases of gastrointestinal bleeding associated with the use of devil's claw root have been reported. A systematic review of the adverse effects of devil's claw root in about 20 randomised, double-blind, placebo-controlled clinical trials showed mainly gastrointestinal effects: gastralgia and dyspepsia. In practice, devil's claw root exposes patients to the risk of sometimes serious upper gastrointestinal disorders, yet has no established efficacy beyond a placebo effect. It is best avoided.

    Objective To observe the therapeutic effect of Qilin Xintongshu pill for treatment of patients with non-ST segment elevation acute coronary syndromes(NSTE-ACS)accompanied by gastrointestinal bleeding (GIB). Methods A prospective randomized controlled trial was conducted. A total of 67 hospitalized patients in Cardiovascular Department of Qionghai City Hospital of Traditional Chinese Medicine were divided into therapy group(35 cases)and control group(32 cases). Both groups were given conventional medical treatment(except anti-coagulative agent). In the therapy group,the patients received Qilin Xintongshu pill(the ingredients consisting of panax pseudo-ginsen,dragon's blood,immature orange fruit,etc.)oral administration,once 5 mg and 3 times a day,while in the control group,the patients accepted clopidogrel orally,once 75 g and once a day,the therapeutic course in both groups being 30 days. The major cardiovascular events(such as death,a newly-happened myocardial infarction(MI),MI secondary,obstinately ischemia)and incidence of massive hemorrhage of gastrointestinal tract were compared between the two groups,and the adverse events were observed. Results After treatment,the incidence of cardiovascular events and massive hemorrhage of gastrointestinal tract in the therapy group were decreased significantly compared to those in the control group 〔incidence of cardiovascular events:8.57%(3/35)vs. 28.13%(9/32), incidence of massive hemorrhage of gastrointestinal tract:2.86%(1/35)vs. 21.88%(7/32),both P<0.05〕. Adverse events were not observed in both groups,and the examinations of blood,urine,liver and renal functions were of no abnormalities before and after treatment. Conclusion Qilin Xintongshu pill can effectively reduce the incidences of cardiovascular events and massive hemorrhage of gastrointestinal tract in patients with NSTE-ACS accompanied by GIB in the therapeutic course of 30 days,therefore this traditional Chinese herbal medicine is an ideal agent for

    Disseminated intravascular coagulation (DIC) is the most frequent coagulation disorder associated with metastatic prostate adenocarcinoma. However, DIC with enhanced fibrinolysis as an initial presentation of prostate cancer is extremely rare. The appropriate treatment to control bleeding in these situations is challenging, controversial, and based on isolated case reports in the literature. A 66-year-old male presented at the emergency department with acute severe spontaneous ecchymoses localized to the limbs, laterocervical hematoma, and hemothorax. Prostate specific antigen level was 385 μg/L, bone scintigraphy revealed multiple bone metastases, and prostate biopsy confirmed adenocarcinoma (Gleason 9; 4 + 5). Laboratory investigation showed a pattern of enhanced fibrinolysis rather than the more common intravascular coagulation mechanism. Epsilon aminocaproic acid in monotherapy was initiated with a clear and rapid control of bleeding manifestations. This rare case of massive bleeding due to DIC with enhanced fibrinolysis as the first manifestation of prostate cancer suggests that in selected cases where the acute bleeding dyscrasia is clearly associated with a dominant fibrinolysis mechanism it is possible to use an approach of monotherapy with antifibrinolytics.

    AIM: To identify clinical parameters, and develop an Upper Gastrointesinal Bleeding (UGIB) Etiology Score for predicting the types of UGIB and validate the score.METHODS: Patients with UGIB who underwent endoscopy within 72 h were enrolled. Clinical and basic laboratory parameters were prospectively collected.Predictive factors for the types of UGIB were identified by univariate and multivariate analyses and were used to generate the UGIB Etiology Score. The best cutoff of the score was defined from the receiver operating curve and prospectively validated in another set of patients with UGIB.RESULTS: Among 261 patients with UGIB, 47 (18%) had variceal and 214 (82%) had non-variceal bleeding.Univariate analysis identified 27 distinct parameters significantly associated with the types of UGIB. Logistic regression analysis identified only 3 independent factors for predicting variceal bleeding;previous diagnosis of cirrhosis or signs of chronic liver disease (OR 22.4, 95% CI 8.3-60.4, P < 0.001), red vomitus (OR4.6, 95% CI 1.8-11.9, P = 0.02), and red nasogastric (NG) aspirate (OR 3.3, 95% CI 1.3-8.3, P = 0.011).The UGIB Etiology Score was calculated from (3.1 x previous diagnosis of cirrhosis or signs of chronic liver disease) + (1.5 × red vornitus) + (1.2 × red NG aspirate), when 1 and 0 are used for the presence and absence of each factor, respectively. Using a cutoff ≥ 3.1, the sensitivity, specificity, accuracy, positive predictive value (PPV), and negative predictive value (NPV) in predicting variceal bleeding were 85%, 81%,82%, 50%, and 96%, respectively. The score was prospectively validated in another set of 195 UGIB cases (46 variceal and 149 non-variceal bleeding). The PPV and NPV of a score ≥3.1 for variceal bleeding were 79% and 97%, respectively.CONCLUSION: The UGIB Etiology Score, composed of 3 parameters, using a cutoff ≥ 3.1 accurately predicted variceal bleeding and may help to guide the choice of initial therapy for UGIB before endoscopy.

    Anticoagulant therapy with vitamin K antagonists (AVK) is an effective treatment and prevention of thrombosis. One of the major disadvantages of the AVK is a risk for serious bleeding. Prothrombin complex concentrates (PCC), fresh frozen plasma (FFP) and vitamin K1 are available for control of these situations. The experience of special team ofthe Scientific Center for Hematology was the basis for presented retrospective study. Three regimens of warfarin-related bleeding were compared: PCC+ VK for several bleeding, FFP+ VK for different clinical situations and VKfor light bleeding. PCC showed himself as effective and safe hemostatic agent. Transfusions of FFP were sometimes not effective, sometimes led to TACO. Supplementation of vitamin K1 for patients of I and II groups provided more stable control of hemostasis. In III group VK vas effective to stop bleeding. Two impotent sings for conclusion: necessary of laboratory monitoring, TEG first of all; individual balance of hemostasis base of bleeding or thrombotic risks.

    There is a clinical need to develop safe and rapid therapeutic strategies to control bleeding arising from a host of emergent situations. Over the past several years our laboratory has developed novel zymogen-like FXa variants and tested their safety and efficacy using hemophilia as a model system. The variants have a spectrum of properties resulting from an amino acid change at the N-terminus of the heavy chain that alters a critical conformational change. These properties, which include resistance to plasma protease inhibitors, low activity in the absence of FVa, and rescue of low activity upon incorporation in prothrombinase, yield remarkably effective pro-hemostatic agents. The FVa-dependent restoration of activity is a key aspect to their efficacy and also contributes to localizing the variants to the site of vascular injury. While pre-clinical data support their use in the setting of hemophilia, they have the potential to act as rapid pro-hemostatic agents for the treatment of a range of bleeding conditions. This review will discuss the biochemical properties of these FXa zymogen-like variants and their in vivo characterization. PMID:27207419

    Full Text Available Leeches are blood-sucking hermaphroditic parasites that attach to vertebrate hosts, bite through the skin, and suck out blood. When leeches feed, they secrete an anticoagulant (hirudin, which helps them get a full meal of blood. This is the first report of leech removal from external auditory canal. Previous leech involvement cases were explained in nasopharynx, larynx, pharynx, eye, and gastrointestinal tract. Prominent sign of all cases was active bleeding from the leech attachment site; that stopped with leech removal. A 24-year-old man was presented to Al-Zahra hospital with left otorrhagia and otalgia from 2 days ago. After suction of ear a small soft foreign body was seen in the external ear near the tympanic membrane, then the ear filled with glycerine phenice, the patient explained decreased movement of foreign body. Four hours later the bloody discharge stopped and otalgia decreased. After suction of clots, a leech was extruded from external auditory canal by alligator. Leech infestation is a rare cause of otorrhagia and should be suspected in the endemic region in all of unusual bleeding; it can be diagnosed and treated by exact inspection and removal.

    Aspirin is increasingly being used for long-term prophylaxis of myocardial infarction and stroke, but its use is limited by toxicity in the gastrointestinal tract. Even very low doses of aspirin can markedly increase the risk of gastrointestinal bleeding and ulceration. While proven effective in prophylaxis of stroke and myocardial infarction, the efficacy of aspirin is limited. Addition of a nitric oxide-releasing moiety to several non-steroidal anti-inflammatory drugs results in a profound reduction in their toxicity in the gastrointestinal tract and kidney. A similar derivatization of aspirin has recently been shown to result in a more potent, gastrointestinal-sparing antithrombotic drug. Two such compounds (NCX-4215 and NCX-4016; NicOx SA) have undergone detailed evaluation thus far. In each case, the NO-aspirin has shown improved anti-aggregatory activity while not inducing detectable gastric damage. The compounds have also been shown to exert protective effects in the gastrointestinal tract exposed to other injurious agents. The NO-aspirin derivatives significantly inhibit leukocyte adherence to the vascular endothelium, which may contribute to their anti-thrombotic activity. NO-releasing derivatives of aspirin and naproxen also exhibit beneficial effects in experimental hypertension, which would also contribute to improved anti-thrombotic activity. NO-releasing derivatives of NSAIDs offer great potential as gastrointestinal-sparing anti-thrombotic drugs. PMID:16158351

    Grouting is a common method of sealing rock around tunnels to reduce or stop water inflow. Successful grouting significantly minimizes the maintenance cost and safety of the tunnel. Some questions about bleeding and penetrability of the grouts have to be examined more closely to carry out a successful grouting. Bleeding of cement-based grout is a complex problem. Measuring methods used today originate from the measuring of the bleeding of cement pastes used in ordinary building industry. Whet...

  20. Performance analysis of bleed condenser used in Indian PHWR

    International Nuclear Information System (INIS)

    Condensation of hot two phase bleed from the Primary Heat Transport (PHT) system is carried out by two different cooling modes in the bleed condenser of Indian PHWRs. These are the reflux and spray cooling modes. A computer code has been developed to predict the performance of bleed condensers used in Indian PHWRs for the above two cooling modes. Using the computer code the performance analysis was carried out for the reflux cooling and spray cooling modes separately. (author). 19 refs., 8 figs

    AIM: To clarify the risk factors for bleeding after endoscopic mucosal resection (EMR).METHODS: A total of 297 consecutive patients who underwent EMR were enrolled. Some of the patients had multiple lesions. Bleeding requiring endoscopic treatment was defined as bleeding after EMR. Odds ratios (OR) with 95% confidence intervals (CI), calculated by logistic regression with multivariate adjustments for covariates,were the measures of association.RESULTS: Of the 297 patients, 57 (19.2%) patients with bleeding after EMR were confirmed. With multivariate adjustment, the cutting method of ENR, diameter, and endoscopic pattern of the tumor were associated with the risk of bleeding after ENR. The multivariate-adjusted OR for bleeding after EMR using endoscopic aspiration mucosectomy was 3.07 (95%CI, 1.59-5.92) compared with strip biopsy. The multiple-adjusted OR for bleeding after EMR for the highest quartile (16-50 mm) of tumor diameter was 5.63 (95%CI, 1.84-17.23) compared with that for the lowest (4-7 mm). The multiple-adjusted OR for bleeding after EM R for depressed type of tumor was 4.21 (95%CI, 1.75-10.10) compared with elevated type.CONCLUSION: It is important to take tumor characteristics (tumor size and endoscopic pattern) and cutting method of EMR into consideration in predicting bleeding after ENR.

    Nonvariceal upper gastrointestinal (UGI) bleeding is a frequent complication with significant morbidity and mortality. Although endoscopic hemostasis remains the initial treatment modality, severe bleeding despite endoscopic management occurs in 5-10% of patients, necessitating surgery or interventional embolotherapy. Endovascular embolotherapy is now considered the first-line therapy for massive UGI bleeding that is refractory to endoscopic management. Interventional radiologists need to be familiar with the choice of embolic materials, technical aspects of embolotherapy, and the factors affecting the favorable or unfavorable outcomes after embolotherapy for UGI bleeding.

    Objective After angiography and embolization of three cases suffering from traumatic artery bleeding we summarized the selective embolization of different artery bleeding cases and their treatment analysis. Methods The three cases were all female,among them,one suffering from hepatic artery bleeding by a traffic accident, the other two caused by iatrogenic damage. Of the two, one suffered from bleeding after the gall bladder removal, the other from bleeding after puncture biopsy through the kidney.Seldinger technique was used on the three cases, and puncture intubation was superselected and put through arterial femoralis. Catheters were put separately inside the target blood vessels to have radiography and contrast medium was found to have out flowed out to the bleeding artery. And then the mixed gelatin sponge particles were put into, Ultravist contrast medium to make suspension. Through fluoroscopy the suspension was injected into bleeding artery until no contrast medium out flowed. After that radiography was used to watch the result. Results After the embolization the three cases stopped bleeding at once with remarkable effects. Conclusion Therefore we conclude the embolization is the best method for treating artery bleeding.

    We present a case in which a patient with acute hemorrhagic gastritis demonstrated abnormal gastrointestinal accumulation of radiotracer during {sup 99m}Tc-methylene diphosphonate (MDP) skeletal scintigraphy. A hemorrhagic gastritis was subsequently demonstrated by endoscopy. The mechanism for the intestinal localization of {sup 99m}Tc-MDP in this patients is not clear, but we guess that the extravasated blood containing the radiopharmaceutical cannot recirculate and stays at the bleeding site, so we can see the intestinal activity.

    Full Text Available Acute upper gastrointestinal (UGI bleeding is a common problem in our clinical practice and is often due to peptic ulcer diseases. Occasionally, malignancy may be implicated in these situations. Here we report a rare case of UGI bleeding secondary to metastatic transitional cell carcinoma (TCC of the urinary bladder. A 62-year-old man with a history of stage IIIb TCC of the urinary bladder presented with hematemesis. Endoscopy showed a large tumor in the second stage of the duodenum that occupied 40% of the duodenal circumference, over 7 cm in length. Biopsies revealed a poorly differentiated malignant neoplasm consistent with metastasis from urothelial carcinoma that was identical to the previous surgical specimen of the urinary bladder. He was treated with supportive therapy and intravenous proton pump inhibitor and was discharged home 2 weeks later. Two weeks after discharge, the patient returned to the hospital with a painful swelling of the floor of his mouth. Biopsy again showed the same cancer type. He had unremitting bleeding from his mouth requiring multiple transfusions and a course of palliative radiation therapy. He progressively deteriorated in his cardiopulmonary and neurological functions and expired with cardiopulmonary arrest one month later.

  8. Helical CT in the diagnosis of acute lower gastrointestinal haemorrhage

    International Nuclear Information System (INIS)

    Introduction: A pilot study to evaluate helical computer tomography (CT) as a diagnostic tool for acute lower gastrointestinal tract (GIT) bleeding. CT was compared to conventional angiography (CA) and colonoscopy for the diagnosis and detection of bleeding site in suspected cases of acute lower GIT bleeding. Methods: Seven patients presenting with acute lower GIT bleeding, between June and November 2002, underwent CT examinations. All of these seven patients underwent CA following CT. Emergency colonoscopies were performed on five patients investigated with both CT and CA. Median delay from the most recent episode of hematochezia to CT was two and a half hours, to CA was 3 h, and to colonoscopy was 4 h. None of the patients underwent nuclear medicine (NM) bleeding studies. Results: Haemoglobin drop in all patients was greater than 15 g/L in the first 24 h of presentation. The mean age was 68.86 years (range, 49-83 years). Comparing CT and CA, there were four concordant and three discordant results. Both modalities had concordant findings of two active bleeding sites, one non-bleeding rectal tumour, and one negative case result. In three patients, the source of bleeding was found on CT whereas CA was negative. Emergency colonoscopies performed in all of these three patients confirmed blood in the colon/ileum. Conclusion: Early experience suggests that CT is a safe, convenient and accurate diagnostic tool for acute lower GIT haemorrhage. It raises questions regarding the sensitivity of CA. A new management algorithm for acute lower GIT haemorrhage using CT as the pre-CA screening tool is being proposed based on the preliminary findings. Positive CT will allow directed therapeutic angiography, while negative CT will triage patients into alternative management pathways

    2014-01-01

    Full Text Available Introduction. Acute abdominal pain may be the presenting symptom in a wide range of diseases in the elderly. Acute abdominal pain related to a delayed bleeding and pelvic haematoma after a low-energy pubic rami fracture is rare and can have important consequences; to the best of our knowledge, only one case has been previously described. Case Report. We present an unusual case of an 83-year-old woman taking warfarin for atrial fibrillation, admitted to the Emergency Department (ED with acute abdominal pain and progressive anemia related to a delayed bleeding and pelvic haematoma 72 hours after a low-energy osteoporotic pubic rami fracture. Warfarin was withheld, anticoagulation was reversed by using fresh frozen plasma and vitamin K, and concentrated red blood cells were given. Haemoglobin level gradually returned to normal with a progressive resorption of the haematoma. Conclusion. Delayed bleeding and pelvic haematoma after osteoporotic pubic rami fracture should be considered in the differential diagnosis of acute abdominal pain in the elderly. This case indicates the need for hospital admission, careful haemodynamic monitoring, and early identification of bleeding in patients with “benign” osteoporotic pubic rami fracture, especially those receiving anticoagulants, to provide an adequate management and prevent severe complications.

    Inherited bleeding disorders are caused by various genetic defects in the proteins involved in haemostasis. Female patients or carriers are faced with the risk of haemorrhage throughout life. During pregnancy and postpartum, this complication affects the health of either the mother or the baby, or both. This retrospective cohort study was designed to assess the occurrence of obstetric bleeding in the three trimesters of pregnancy, along with primary and secondary postpartum haemorrhage among 100 women with inherited bleeding disorders. A questionnaire was designed in order to collect historical data. The patients were evaluated in three groups: haemophilia carriers, von Willebrand disease (VWD) and rare bleeding disorders. In comparison with normal women, significantly severe bleeding was observed among patients in all of the five stages. VWD patients showed a higher frequency of bleeding in first trimester but the rate of miscarriage was lower. Haemophilia carriers were threatened with bleeding complications during the prenatal period, but they also had the highest frequency of postpartum haemorrhage. Based on our results, vaginal bleeding is a serious threat in all three patient groups, especially during the first trimester of pregnancy and in the postpartum period. PMID:22821002

    2016-04-01

    There has been a concern that major bleeding events (MBE) on direct-acting oral anticoagulants (DOACs) will be more difficult to manage than on vitamin K antagonists. Patients with cancer and DOAC-associated bleeding may be even more of a challenge to manage. We therefore reviewed the literature on bleeding in patients with cancer on DOACs. In addition, we performed an analysis of individual patient data from 5 phase III trials on treatment with dabigatran with focus on those with cancer. In 6 randomized trials the risk of MBE in patients with cancer was similar on treatment with DOACs compared to vitamin K antagonists. Bleeding was in the majority of patients managed with supportive therapy alone. In the individual patient data analysis there were no significant differences in use of hemostatic products, transfusion of red cells, effectiveness of management, bleeding-related mortality or 30-day all-cause mortality between patients with cancer treated with dabigatran or with warfarin. Local hemostatic therapy, including resection of the cancer site was more common in patients with gastrointestinal bleeding with cancer than among those without cancer. We conclude that management of bleeding in patients with cancer and on a DOAC does not pose a greater challenge than management of bleeding in patients without cancer. PMID:27067968

    Objective To investigate the mechanisms of abnormal bleeding in patients with anovulatory dysfunctional uterine bleeding (DUB) and to analyze the correlation between vascular endothelial growth factor (VEGF) and microvessel density in the endometrium Materials & Methods Immunohistochemistry was used to study the expression of VEGF protein in the proliferative and hyperplastic endometrium. CD34 ,a marker of microvessel, was selected to measure microvessel density (MVD) in the endometrium.Fifteen women who were found to have no condition with normal menstrual cycles were set as control group.Results VEGF immunoreactivity in glandular epithelia cells was significantly lower in the hyperplastic endometrium than that of controls(P < 0. 05). There was no significant difference in VEGF protein level between proliferative DUB endometrium and that of controls. A positive correlation was found between glandular VEGF and MVD in the endometrium(r=0. 666, P<0.05). Conclusion The anovulatory DUB is associated with down-regulation of VEGF in the endometrium, and decreased secretion of VEGF will result in the disruption of angiogenesis, as a clinical manifestation of irregular bleeding.

    This study assesses the comparative effectiveness of three types of dental floss and toothbrushing in reducing interproximal bleeding sites, measured by stimulation with wooden interdental cleaners using the interdental bleeding index assessment method. The 119 adult subjects with gingival inflammation were randomly assigned to one of four groups at the beginning of a supervised 2 week clinical trial. The toothbrushing only group achieved a 35% reduction in bleeding sites and the three flossing groups all demonstrated dramatic reductions of about 67%. The three varieties of dental flosses were about equally effective in reducing interproximal bleeding and doubly effective as toothbrushing alone. Compared to probing, the interdental bleeding index method is considered a simplified method of assessing interproximal gingival inflammation.

    Obscure gastrointestinal bleeding is still a clinical challenge for gastroenterologists. The recent development of novel technologies for the diagnosis and treatment of different bleeding causes has allowed a better management of patients, but it also determines the need of a deeper comprehension of pathophysiology and the analysis of local expertise in order to develop a rational management algorithm. Obscure gastrointestinal bleeding can be divided in occult, when a positive occult blood fecal test is the main manifestation, and overt, when external sings of bleeding are visible. In this paper we are going to focus on overt gastrointestinal bleeding, describing the physiopathology of the most usual causes, analyzing the diagnostic procedures available, from the most classical to the novel ones, and establishing a standard algorithm which can be adapted depending on the local expertise or availability. Finally, we will review the main therapeutic options for this complex and not so uncommon clinical problem.

    Purpose: To describe how peristomal varices can be successfully embolized via a percutaneous parastomal approach. Methods: The medical records of patients who underwent this procedure between December 1, 2000, and May 31, 2008, were retrospectively reviewed. Procedural details were recorded. Median fluoroscopy time and bleeding-free interval were calculated. Results: Seven patients underwent eight parastomal embolizations. The technical success rate was 88 % (one failure). All embolizations were performed with coils combined with a sclerosant, another embolizing agent, or both. Of the seven successful parastomal embolizations, there were three cases of recurrent bleeding; the median time to rebleeding was 45 days (range 26-313 days). The remaining four patients did not develop recurrent bleeding during the follow-up period; their median bleeding-free interval was 131 days (range 40-659 days). Conclusion: This case review demonstrated that percutaneous parastomal embolization is a feasible technique to treat bleeding peristomal varices.

    Full Text Available Abstract Objective To determine the frequency and clinical features of bleeding disorders in the tribe as a result of consanguineous marriages. Design Cross Sectional Study Introduction Countries in which consanguinity is a normal practice, these rare autosomal recessive disorders run in close families and tribes. Here we describe a family, living in village Ali Murad Chandio, District Badin, labeled as haemophilia. Patients & Methods Our team visited the village & developed the pedigree of the whole extended family, up to seven generations. Performa was filled by incorporating patients, family history of bleeding, signs & symptoms, and bleeding from any site. From them 144 individuals were screened with CBC, bleeding time, platelet aggregation studies & RiCoF. While for PT, APTT, VWF assay and Factor VIII assay, samples were kept frozen at -70 degrees C until tested. Results The family tree of the seven generations comprises of 533 individuals, 63 subjects died over a period of 20 years and 470 were alive. Out of all those 144 subjects were selected on the basis of the bleeding history. Among them 98(68.1% were diagnosed to have a bleeding disorder; 44.9% patients were male and 55.1% patients were female. Median age of all the patients was 20.81, range (4 months- 80 yrs. The results of bleeding have shown that majority had gum bleeding, epistaxis and menorrhagia. Most common bleeding disorder was Von Willebrand disease and Platelet functional disorders. Conclusion Consanguineous marriages keep all the beneficial and adversely affecting recessive genes within the family; in homozygous states. These genes express themselves and result in life threatening diseases. Awareness, education & genetic counseling will be needed to prevent the spread of such common occurrence of these bleeding disorders in the community.

    AIM: Helicobacter pyloricauses chronic gastritis, peptic ulcer,gastric cancer and MALT-lymphoma. Different genotypes of Helicobacter pylori are confirmed from diverse geographic areas. Its association with bleeding peptic ulcer remains controversial. The aim of this study was to investigate the Helicobacter pylori vac4 alleles, cagA and iceA in patients with bleeding peptic ulcer.METHODS: We enrolled patients with bleeding, nonbleeding peptic ulcers and chronic gastritis. Biopsy specimens were obtained from the antrum of the stomach for rapid urease test, bacterial culture and PCR assay. DNA extraction and polymerase chain reaction were used to detect the presence or absence of cagA and to assess the polymorphism of vac4 and iceA.RESULTS: A total of 168 patients (60.4%) (25 patients with chronic gastritis, 26 patients with bleeding gastric ulcer,51 patients with non-bleeding gastric ulcer, 26 patients with bleeding duodenal ulcer, and 40 patients with non-bleeding duodenal ulcer) were found to have positive PCR results between January 2001 and December 2002. Concerning genotypes, we found cagA (139/278, 50%), vacA s1a (127/278, 45.7%), and iceA1 (125/278, 45%) predominated in all studied patients. In patients with bleeding peptic ulcers,vac4 s1a and m1T were fewer than those in patients with non-bleeding peptic ulcers (37/106 vs69/135, P=0.017, and 4/106 vs21/135, P=0.002).CONCLUSION: In patients with peptic ulcers, Hpylori vacA s1a and m1T prevent bleeding complication.

    Philadelphia-negative myeloproliferative neoplasms (Ph-negative MPN) comprise a heterogeneous group of chronic hematologic malignancies. The quality of life, morbidity, and mortality of patients with MPN are primarily affected by disease-related symptoms, thromboembolic and hemorrhagic complications, and progression to myelofibrosis and acute leukemia. Major bleeding represents a common and important complication in MPN, and the incidence of such bleeding events will become even more relevant in the future due to the increasing disease prevalence and survival of MPN patients. This review discusses the causes, differential diagnoses, prevention, and management of bleeding episodes in patients with MPN, aiming at defining updated standards of care in these often challenging situations.

    On the basis of geometrical optics approximation (GOA) of light scattering by spheres, GOA method of forward scattering by a GI-POF for normally incident plane wave was presented. The convergence factor and the phase shift caused by focal line were deduced in GOA. The nondimensional form of scattering intensity formula of forward scattering by a GI-POF for normally incident plane wave was obtained. Based on the above work, the scattering intensity distribution and calculation speed calculated by GOA was compared with the result calculated by Mie theory. The comparison result shows that GOA can be used to calculate the forward scattering intensity of a GI-POF with normally incident plane wave exactly. And the calculation speed of GOA is higher than that of Mie theory, the GOA method is suitable for the real-time measurement of particle-sizing.%基于球粒子光散射的几何光学近似方法,推导了平面波垂直入射梯度折射率光纤(GI-POF)前向散射的几何光学近似.详细推导了几何光学近似方法中的收敛因子和焦线引起的相位变化,得到了平面波垂直入射到GI-POF时无量纲散射强度公式.在此基础上,将几何光学近似方法计算出的前向散射强度分布和算法的运行速度与Mie理论进行了对比,结果表明:几何光学近似方法可以快速而准确地计算出粒子前向散射分布,适用于粒度的在线测量.

    AIM: To prospectively evaluate the indications, methodology, safety, and clinical impact of double-balloon endoscopy.METHODS: A total of 60 patients with suspected or documented small- or large-bowel diseases were investigated by double balloon endoscopy. A total of 103 procedures were performed (42 from the oral route, 60 from the anal route, and 1 from the stoma route). The main outcome measurements were the time of insertion and the entire examination, complications, diagnostic yields,and the ability to successfully perform treatment.RESULTS: Observation of the entire small intestine was possible in 10 (40%) of 25 patients with total enteroscopy. The median insertion time was 122 min (range,74-199 min). Observation of the entire colon was possibie in 13 (93%) of 14 patients after failure of total colonoscopy using a conventional colonoscope. Small-intestine abnormalities were found in 20 (43%) of 46 patients with indications of suspected or documented small bowel diseases, obscure GI tract bleeding, or a history of ileus.Endoscopic procedures including tattooing (n = 33), bite biopsy (n = 17), radiographic examination (n = 7), EUS (n = 5), hemostasis (n = 1), polypectomy (n = 5), balloon dilatation (n = 1), endoscopic mucosal resection (n = 1)and lithotripsy (n = 1) were all successfully performed.No relevant technical problems or severe complications were encountered.CONCLUSION: Double balloon endoscopy is a feasible technique that allows adequate small and large bowel examination and potentially various endoscopic procedures of small-intestinal lesions. Tt is safe, useful, and also provides a high clinical impact.

    2005-01-01

    Full Text Available Upper gastro-intestinal bleeding remains a cornerstone in surgical practice and unfortunately its’ management is profoundly variable according to hospital protocols and local standards of care. Medical interventions are acting at different levels of medical care and a range of specialist are involved in the process, starting from family practitioners to surgeons, as well as highly trained specialist in interventional endoscopy or radiology. This review is trying to establish the landmarks in the early assessment and care of patients with upper gastro-intestinal bleeding, irrespective of the morphological cause of the bleeding. We propose a protocol for the management both of portal and non-portal upper-gastrointestinal bleedings, prior to endoscopic diagnosis. It is fundamental to establish a standard of care which is feasible in Romania and can work both in university and district hospitals. The protocol is marking the essential gestures with their relevance for the bleeding patient but also reminds the significance of clinical evaluation and safety in transportation of the patient to the nearest emergency room. A battery of simple test should be performed in every patient and data interpreted with care, as results vary according to the level of haemodynamic compensation. Standard empiric therapy for upper gastro-intestinal bleeding is not yet been established but a couple of alternatives emerge as possible solutions. We discuss the benefits of a standard therapy based on H2 blockers, proton pump inhibitors, octreoctide and somatostatin regarding both portal and non-portal bleedings.

    2016-07-01

    Selected quality issues pertinent to the determination of accurate results in the haemostasis laboratory are discussed. Specifically, the implementation of a successful external quality-assessment scheme is described, including its impact on result accuracy as well as the programme's unique challenges and opportunities. Errors in the preanalytical phase of laboratory testing represent the greatest source for reporting incorrect test results. Some of the most common preanalytical errors are described including those that necessitate sample rejection. Analytical means to identify potential sources of error and analytical means to overcome particular interferences are described. Representing the most important clinical complication in the treatment of patients with haemophilia, quality issues related to determination of the presence of inhibitory antibodies against factor VIII (FVIII) are reviewed. Heat treatment of patient plasma prior to testing, particularly in patients receiving replacement FVIII concentrate or during induction of immune tolerance to achieve more accurate results is recommended, while screening activated partial thromboplastin time-based mixing tests to rule out inhibitor presence is discouraged. The initiatives presented in this review can be implemented in robust and resource restricted settings to improve the quality of laboratory testing in patients with bleeding disorders. PMID:27405682

    Full Text Available Abstract Background One of the rare presentations of superior vena cava syndrome is bleeding of "downhill" esophageal varices (DEV and different approaches have been used to control it. This is a case report whose DEV was eradicated by band ligation for the first time. Case presentation We report a 42-year-old man who is a known case of Behcet's disease. The patient's first presentation was superior vena cava syndrome due to thrombosis followed by bipolar ulcers and arthralgia. He received warfarin, prednisolone and azathioprine. The clinical course of the patient was complicated by one episode of hematemesis without abdominal pain when the patient's PT was in therapeutic range. After resuscitation and correction of PT with fresh frozen plasma transfusion, upper gastrointestinal endoscopy was done. Prominent varices were seen in the upper third of the esophagus, tapering to the middle part without acute bleeding. Stomach and duodenum were normal. Color ultrasonography evaluation of the portal, hepatic and splenic veins was negative for thrombosis. Band ligation was done and the patient's bleeding did not recur. Conclusion Band ligation is a safe and effective method for controlling DEV bleeding in patients with uncorrectable underlying disorders.

    Full Text Available Abstract Background Percutaneous nephrolithotomy is a minimally invasive intervention for renal stone disease. Complications, which are rare and usually presented as case reports, are diversified as the utilization of the procedure is expanded. The procedure causes less blood loss and less morbidity when compared to open surgical procedures. Yet, there are some reports involving severe bleeding and relevant morbidity during surgery. These are usually related with the surgical technique or experience of the surgeon. Renal sheaths are designed to cause minimal trauma inside the kidney and, to our knowledge, there are no reports presenting the rupture of a sheath causing severe bleeding during the procedure. Case report We present an adult patient who had severe bleeding during percutaneous nephrolithotomy due to parenchymal injury caused by a ruptured renal sheath. During retrieval, due probably to rough handling of the equipment, a piece of stone with serrated edges ruptured the tip of the sheath, and this tip caused damage inside the kidney. The operation was terminated and measures were taken to control bleeding. The patient was transfused with a total of 1600 ml of blood, and the stones were cleared in a second look operation. Conclusion Although considered to be a minimally invasive procedure, some unexpected complications may arise during percutaneous nephrolithotomy. After being fragmanted, stone pieces may damage surgical equipment, causing acute and severe harm to the kidney. Surgeons must manipulate the equipment with fine and careful movements in order to prevent this situation.

    Full Text Available Background: Selective serotonin reuptake inhibitors (SSRIs are commonly prescribed agents for various conditions in general psychiatry. There is a strong consensus that blockade of serotonin reuptake affects primary hemostasis, namely platelet activity, thus resulting in a bleeding tendency. Considering that SSRIs are commonly prescribed, this study was conducted to assess if they were associated with an increased risk of bleeding. Methods: This was a prospective, open-label study of 30 patients attending the Psychiatry out-patient department, Dr. B. R. Ambedkar Medical College, Bangalore who satisfied DSM-IV criteria for a primary diagnosis of depression, treated with SSRIs. Bleeding time, clotting time, prothrombin time, partial thromboplastin time and platelet count were assessed at baseline and at the end of 6 weeks of treatment or occurrence of bleeding symptom. Results: The patients aged between 18-55 years of whom 21 were females, were treated with an SSRI (fluoxetine 12, escitalopram 12 and sertraline 6 patients. Six patients had overt symptoms of bleeding (upper gastrointestinal bleeding (hematemesis 4; epistaxis 2 and petechiae 2 of whom one patient gave a history of both hematemesis and petechiae and another of hematemesis and epistaxis. The average day after treatment beginning, on which patients reported with bleeding was 30.33 (26-40 days. There was a significant increase in the bleeding time (p=0.028 and clotting time (p=0.042, implying derangement in platelet aggregation. There was no significant change in the other parameters. Conclusion: Treatment with SSRIs increases the risk of bleeding. However, large, randomized controlled trials are required to re-affirm these findings.

    Chordoma is a rare cartilaginous tumor, for which bleeding presentation is unusual. We report a case of rare hemorrhaged clival chordoma, which was diagnosed correctly by magnetic resonance imaging. A 32-year-old man presented with nasal bleeding. The tumor was totally removed via a trans-sphenoidal approach, from which the surgical specimen confirmed chordoma. Epistaxis seemed to be caused by the spreading of the intratumoral hemorrhage into the sphenoid sinus. This case demonstrates the importance of an exact differential diagnostic evaluation, including chordoma, by use of modern imaging techniques for nasal bleeding. (orig.)

    2007-03-01

    Deep hypothermic circulatory arrest (DHCA) is a technique of extracorporeal circulation commonly used in children with complex congenital heart defects undergoing surgical repairs. The use of profound cooling (20 degrees C) and complete cessation of circulation allow adequate exposure and correction of these complex lesions, with enhanced cerebral protection. However, the profound physiologic state of DHCA results in significant derangement of the coagulation system and a high incidence of postoperative bleeding. This review examines the impact of DHCA on bleeding and transfusion requirements in children and the pathophysiology of DHCA-induced platelet dysfunction. It also focuses on possible pharmacologic interventions to decrease bleeding following DHCA in children. PMID:17484172

    Abstract Gastrointestinal (GI) fistula is a well-recognized complication of acute pancreatitis (AP). However, it has been reported in limited literature. This study aimed to evaluate the incidence and outcome of GI fistulas in AP patients complicated with infected pancreatic or peripancreatic necrosis (IPN). Between 2010 and 2013 AP patients with IPN who diagnosed with GI fistula in our center were analyzed in this retrospective study. And we also conducted a comparison between patients with and without GI fistula regarding the baseline characteristics and outcomes. Over 4 years, a total of 928 AP patients were admitted into our center, of whom 119 patients with IPN were diagnosed with GI fistula and they developed 160 GI fistulas in total. Colonic fistula found in 72 patients was the most common form of GI fistula followed with duodenal fistula. All duodenal fistulas were managed by nonsurgical management. Ileostomy or colostomy was performed for 44 (61.1%) of 72 colonic fistulas. Twenty-one (29.2%) colonic fistulas were successfully treated by percutaneous drainage or continuous negative pressure irrigation. Mortality of patients with GI fistula did not differ significantly from those without GI fistula (28.6% vs 21.9%, P = 0.22). However, a significantly higher mortality (34.7%) was observed in those with colonic fistula. GI fistula is a common finding in patients of AP with IPN. Most of these fistulas can be successfully managed with different procedures depending on their sites of origin. Colonic fistula is related with higher mortality than those without GI fistula.

    2010-05-01

    To the aim of setting up a Spatial Data Infrastructures (SDI) the creation of a system for the metadata management and discovery plays a fundamental role. An effective solution is the use of a geoportal (e.g. FAO/ESA geoportal), that has the important benefit of being accessible from a web browser. With this work we present a solution based integrating two of the available frameworks: GeoNetwork and GI-cat. GeoNetwork is an opensource software designed to improve accessibility of a wide variety of data together with the associated ancillary information (metadata), at different scale and from multidisciplinary sources; data are organized and documented in a standard and consistent way. GeoNetwork implements both the Portal and Catalog components of a Spatial Data Infrastructure (SDI) defined in the OGC Reference Architecture. It provides tools for managing and publishing metadata on spatial data and related services. GeoNetwork allows harvesting of various types of web data sources e.g. OGC Web Services (e.g. CSW, WCS, WMS). GI-cat is a distributed catalog based on a service-oriented framework of modular components and can be customized and tailored to support different deployment scenarios. It can federate a multiplicity of catalogs services, as well as inventory and access services in order to discover and access heterogeneous ESS resources. The federated resources are exposed by GI-cat through several standard catalog interfaces (e.g. OGC CSW AP ISO, OpenSearch, etc.) and by the GI-cat extended interface. Specific components implement mediation services for interfacing heterogeneous service providers, each of which exposes a specific standard specification; such components are called Accessors. These mediating components solve providers data modelmultiplicity by mapping them onto the GI-cat internal data model which implements the ISO 19115 Core profile. Accessors also implement the query protocol mapping; first they translate the query requests expressed

    Gastrointestinal (GI) perforation accounts for over 90% of acute abdomen and pneumoperitoneum. The presence of pneumoperitoneum secondary to spontaneously perforated pyometra is an interesting yet confusing finding given the absence of gastrointestinal (GI) perforation, because pyometra is more common in postmenopausal women. We report an instructive case of diffuse peritonitis caused by spontaneous perforation of pyometra. A 70-year-old postmenopausal female was admitted to surgical emergenc...

    Early after HIV infection there is substantial depletion of CD4+ T cells in the gastrointestinal (GI) tract lamina propria (LP), with associated epithelial barrier damage, leading to microbial translocation and systemic inflammation and immune activation. In this study, we analyzed these early events in the GI tract in a cohort of Thai acute HIV-infected patients and determined the effect of early combination antiretroviral treatment (cART). HIV-uninfected and chronically and acutely HIV-infected patients at different Fiebig stages (I–V) underwent colonic biopsies and then received cART. Immunohistochemistry and quantitative image analysis were performed on cross-sectional and longitudinal colon biopsy specimens (day 0 to week 96) to measure GI tract damage (infiltration of polymorphonuclear cells), inflammation (M×1, TNF-α), immune activation (Ki-67), and the CD4+ T cell population in the LP. The magnitude of GI tract damage, immune activation, and inflammation was significantly increased, with significantly depleted CD4+ T cells in the LP in all acutely infected groups prior to cART compared with HIV-uninfected control participants. While most patients treated during acute infection resolved GI tract inflammation and immune activation back to baseline levels after 24 weeks of cART, most acutely infected participants did not restore their CD4+ T cells after 96 weeks of cART.

    A young woman with acute myelocytic leukemia developed acute lower gastrointestinal bleeding immediately after a first remission induction of her leukemia. After the site of bleeding was located in the descending colon, a necrotic bleeding ulcer was resected. Histologic examination of the ulcer established the diagnosis of gastrointestinal mucormycosis. Treatment with amphotericin B was administered because of the high risk of dissemination. The patient has been followed for 9 months with no evidence of relapse of infection. Survival after gastrointestinal mucormycosis in acute leukemia has not previously been reported in the English language literature. Success in managing mucormycosis depends on the adherence to the recommended principles of early aggressive diagnostic measures, excisional surgery, amphotericin B therapy, and control of the underlying predisposing condition.

    A system and method for correcting a large fuel cell voltage spread for a split sub-stack fuel cell system. The system includes a hydrogen source that provides hydrogen to each split sub-stack and bleed valves for bleeding the anode side of the sub-stacks. The system also includes a voltage measuring device for measuring the voltage of each cell in the split sub-stacks. The system provides two levels for correcting a large stack voltage spread problem. The first level includes sending fresh hydrogen to the weak sub-stack well before a normal reactive bleed would occur, and the second level includes sending fresh hydrogen to the weak sub-stack and opening the bleed valve of the other sub-stack when the cell voltage spread is close to stack failure.

  13. A rare cause of recurrent gastrointestinal bleeding: mesenteric hemangioma

    Full Text Available Abstract Lower gastrointestinal hemorrhage accounts for approximately 20% of gastrointestinal hemorrhage. The most common causes of lower gastrointestinal hemorrhage in adults are diverticular disease, inflammatory bowel disease, benign anorectal diseases, intestinal neoplasias, coagulopathies and arterio-venous malformations. Hemangiomas of gastrointestinal tract are rare. Mesenteric hemangiomas are also extremely rare. We present a 25-year-old female who was admitted to the emergency room with recurrent lower gastrointestinal bleeding. An intraluminal bleeding mass inside the small intestinal segment was detected during explorative laparotomy as the cause of the recurrent lower gastrointestinal bleeding. After partial resection of small bowel segment, the histopathologic examination revealed a cavernous hemagioma of mesenteric origin. Although rare, gastrointestinal hemangioma should be thought in differential diagnosis as a cause of recurrent lower gastrointestinal bleeding.

    Objectives: Several endoscopic techniques have been proposed for the management of post-sphincterotomy bleeding. Lately, self-expandable metal stents deployment has gained popularity especially as a rescue therapy when other endoscopic techniques fail. Methods-results: We report the case report of a massive post-sphincterotomy bleeding in a patient with a self-expandable metal stent in the biliary tree. Despite the presence of a correctly positioned self-expandable metal stent, a new endoscopic session was required to control the bleeding. Conclusions: Self-expandable metal stent may be useful to manage post-endoscopic sphincterotomy bleeding. However, up to now there is no specifically designed self-expandable metal stent for such complication. Large new designed self-expandable metal stent may be a useful tool for biliary endoscopist.

    2014-03-01

    Full Text Available Despite the success of therapeutic treatment of peptic ulcer and the introduction of endoscopic technologies, the problem of peptic ulcer hemorrhage remains valid. A large number of publications in foreign literature are dedicated to epidemiology and prevention of bleeding, evaluation of modern tactics and search for new methods of treatment. The works relating to organization of aid to patients with peptic ulcer bleeding are of particular interest. According to the recent data not all clinics even in economically developed countries manage to follow the recommendations of an international consensus-2010 for non-variceal bleeding treatment of upper gastrointestinal tract. Among the causes of non-compliance of international recommendations there are subjective and objective factors, the understanding of which can significantly affect the optimization of aid to patients with peptic ulcer bleeding.

    @@ Esophageal variceal bleeding (EVB), a severe complication and main mortality cause of portal hypertension, had reached a relatively mature stage in its research. The mortality rate of EVB within 5 days showed decreased tendency in recent years, which may be due to wide adoption of endoscopic variceal ligation (EVL) and endoscopic injection sclerotherapy (EIS).1 Endoscopic treatment had been widely used because of its simple procedure, high hemostasis rate and low recurrent bleeding rate, and had become a main measure in cease of first episode and prevention of recurrent bleeding. The technique of endoscopic procedures had less progress in the last 5 years. Recent studies on EVB mainly focused on further improvement of clinical outcome, including primary prevention by EVL, selection and combination of different hemostatic measures, minimizing complications, better long-term management and forecast of bleeding risk.

    Saunders, J. David; Davis, David; Barsi, Stephen J.; Deans, Matthew C.; Weir, Lois J.; Sanders, Bobby W.

    2014-01-01

    A mission analysis code was developed to perform a trade study on the effectiveness of liquefying bleed for the inlet of the first stage of a TSTO vehicle. By liquefying bleed, the vehicle weight (TOGW) could be reduced by 7 to 23%. Numerous simplifying assumptions were made and lessons were learned. Increased accuracy in future analyses can be achieved by: Including a higher fidelity model to capture the effect of rescaling (variable vehicle TOGW). Refining specific thrust and impulse models ( T m a and Isp) to preserve fuel-to-air ratio. Implementing LH2 for T m a and Isp. Correlating baseline design to other mission analyses and correcting vehicle design elements. Implementing angle-of-attack effects on inlet characteristics. Refining aerodynamic performance (to improve L/D ratio at higher Mach numbers). Examining the benefit with partial cooling or densification of the bleed air stream. Incorporating higher fidelity weight estimates for the liquefied bleed system (heat exchange and liquid storage versus bleed duct weights) could be added when more fully developed. Adding trim drag or 6-degree-of-freedom trajectory analysis for higher fidelity. Investigating vehicle optimization for each of the bleed configurations.

    2005-04-01

    Objective: To investigate the application of ultrasound contrast agents (UCA) in improving both therapeutic and diagnostic aspects of ultrasound-guided High Intensity Focused Ultrasound (HIFU) therapy. Methods: Incisions (3 cm long, 0.5 cm deep) were made in rabbit livers (in anterior surface for HIFU treatment, or posterior surface for bleeding detection). UCA Optison (~0.1 ml/kg) was injected into mesenteric vein or ear vein. A HIFU applicator (5.5 MHz, 6400 W/cm2) was scanned manually over the incision until hemostasis was achieved. Occult bleeding was monitored with Doppler ultrasound. Results: The presence of Optison produced 37% reduction in hemostasis times normalized to initial bleeding rates. Gross and histological observations showed similar appearance of HIFU lesions produced in the presence of Optison and control HIFU lesions. The temperature reached 100°C in both HIFU only and HIFU+UCA treatments. Tension strength of hemostatic liver incisions was 0.9+/-0.5 N. Almost no bleeding could be detected before Optison injection. First appearance of contrast enhancement localized at the bleeding site was 15 s after Optison injection, and lasted for ~50 s. Conclusion: The presence of UCA during HIFU treatment of liver incisions resulted in shortening of HIFU application times and better visualization of bleeding sites.

    The clinical presentation of congenital portosystemic shunt is variable and gastrointestinal bleeding is an uncommon presentation. To describe the imaging features of congenital portosystemic shunt as it presented in 11 children with (n = 6) and without gastrointestinal bleeding (n = 5). We performed a retrospective study on a clinical and imaging dataset of 11 children diagnosed with congenital portosystemic shunt. A total of 11 children with congenital portosystemic shunt were included in this study, 7 with extrahepatic portosystemic shunts and 4 with intrahepatic portosystemic shunts. Six patients with gastrointestinal bleeding had an extrahepatic portosystemic shunt, and the imaging results showed that the shunts originated from the splenomesenteric junction (n = 5) or splenic vein (n = 1) and connected to the internal iliac vein. Among the five cases of congenital portosystemic shunt without gastrointestinal bleeding, one case was an extrahepatic portosystemic shunt and the other four were intrahepatic portosystemic shunts. Most congenital portosystemic shunt patients with gastrointestinal bleeding had a shunt that drained portal blood into the iliac vein via an inferior mesenteric vein. This type of shunt was uncommon, but the concomitant rate of gastrointestinal bleeding with this type of shunt was high. (orig.)

    2016-01-01

    Endoscopic submucosal dissection (ESD) has become widely accepted as a standard method of treatment for superficial gastrointestinal neoplasms because it enables en block resection even for large lesions or fibrotic lesions with minimal invasiveness, and decreases the local recurrence rate. Moreover, specimens resected in an en block fashion enable accurate histological assessment. Taking these factors into consideration, ESD seems to be more advantageous than conventional endoscopic mucosal resection (EMR), but the associated risks of perioperative adverse events are higher than in EMR. Bleeding after ESD is the most frequent among these adverse events. Although post-ESD bleeding can be controlled by endoscopic hemostasis in most cases, it may lead to serious conditions including hemorrhagic shock. Even with preventive methods including administration of acid secretion inhibitors and preventive hemostasis, post-ESD bleeding cannot be completely prevented. In addition high-risk cases for post-ESD bleeding, which include cases with the use of antithrombotic agents or which require large resection, are increasing. Although there have been many reports about associated risk factors and methods of preventing post-ESD bleeding, many issues remain unsolved. Therefore, in this review, we have overviewed risk factors and methods of preventing post-ESD bleeding from previous studies. Endoscopists should have sufficient knowledge of these risk factors and preventive methods when performing ESD.

    2016-03-01

    To meet the increasing demand for board level high speed data transmission in the area of high performance computing, much attention has been paid to employ high performance polymer optical waveguide. So far, optical interconnects have been considered to have advantages over electronic solutions in various aspects, such as lower power consumption, larger information carrying capacity and immunity to crosstalk. It is one of the advantages that waveguides are possible to be curved and crossed light paths in the same circuit plane. GI-core polymer waveguides are capable of confining the signal light around the core center more tightly, by which the GI-core waveguides exhibit low propagation loss, low crosstalk, and low modal dispersion. Therefore, GI-core reduces the loss in meshed waveguide compared to SI-core meshed waveguides. The material of our GI-core polymer waveguide is Polynorbornene. The varnish for both core and cladding is prepared and coated onto a substrate then the coated layers are exposed to a UV light through a photomask and heated at a certain temperature. After heating, index profile changes and GI-core waveguide is formed. This is our original photo-addressing method. We confirm that extremely low crossings loss is observed in both 90-degree (0.53 dB/500 crosses) and 45-degree (1.55 dB/500 crosses). Also, we succeed high-speed data transmission. We expect that this ultra low crossing loss GI-core waveguide will be one of the promising components giving a strong impact on high performance computing systems in near future.

    2003-06-01

    To assess the feasibility of balloon-occluded retrograde transvenous obliteration (BRTO) in active gastric variceal bleeding, and to compare the findings with those of transjugular intrahepatic portosystemic shunt (TIPS). Twenty-one patients with active gastric variceal bleeding due to liver cirrhosis were referred for radiological intervention. In 15 patients, contrast-enhanced CT scans demonstrated gastrorenal shunt, and the remaining six (Group 1) underwent TIPS. Seven of the 15 with gastrorenal shunt (Group 2) were also treated with TIPS, and the other eight (Group 3) underwent BRTO. All patients were followed up for 6 to 21 (mean, 14.4) months. For statistical inter-group comparison of immediate hemostasis, rebleeding and encephalopathy, Fisher's exact test was used. Changes in the Child-Pugh score before and after each procedure in each group were statistically analyzed by means of Wilcoxon's signed rank test. One patient in Group 1 died of sepsis, acute respiratory distress syndrome, and persistent bleeding three days after TIPS, while the remaining 20 survived the procedure with immediate hemostasis. Hepatic encephalopathy developed in four patients (one in Group 1, three in Group 2, and none in Group 3); one, in Group 2, died while in an hepatic coma 19 months after TIPS. Rebleeding occurred in one patient, also in Group 2. Except for transient fever in two Group-3 patients, no procedure-related complication occurred. In terms of immediate hemostasis, rebleeding and encephalopathy, there were no statistically significant differences between the groups (p > 0.05). In Group 3, the Child-Pugh score showed a significant decrease after the procedure (p = 0.02). BRTO can effectively control active gastric variceal bleeding, and because of immediate hemostasis, the absence of rebleeding, and improved liver function, is a good alternative to TIPS in patients in whom such bleeding, accompanied by gastrorenal shunt, occurs.

    Objective: To investigate the clinical efficacy of estrogen or contraceptives in the treatment of acute bleeding of dysfunctional uterine bleeding (DUB) in adolescent patients and the optimal starting dosage of drugs.Methods: The clinical records of 106 girls who with DUB and moderate or severe anemia from February 1990 to July 2005 were analyzed retrospectively.Results: All 106 patients received hormonal therapy. 56 patients were treated with estradiol benzoate(E2), 30 patients with conjugated equine estrogen(CEE) and 20 patients with combined oral contraceptives (COCs). The rates for rapidly controlling bleeding and for rapidly stopping bleeding in E2 group were higher than those in CEE group ,but similar to those in COCs group. The days for controlling and completely stopping bleeding were not significantly different between the starting dosages (≤8 mg/d and >8 mg/d) of E2 groups, and also there were no statistical difference between the starting dosages (<7.5 mg/d and ≥7.5 mg/d) of CEE groups, but during the treatment the rate of increasing the dosage in <7.5 mg/d group was higher than that of ≥7.5 mg/d group(40% vs. 5%),while there were no statistical difference between the starting dosages (≤3 pills/d and >3 pills/d) of COCs groups. Conclusions: The clinical efficiency of E2 treatment on DUB in adolescent patients is similar to that of COCs. And the efficacies of treatment of DUB with E2, CEE and COCs in the different dosages are similar.

    2005-01-01

    Full Text Available The departure process of a single queue has been studied since the 1960s. Due to its inherent complexity, closed form solutions for the distribution of the departure process are nearly intractable. In this study, kernel type estimators of the density of interdeparture time in a GI/G/1 queue are studied. Uniform strong consistency of the estimators in a GI/G/1 queue and their rates of convergence are obtained. The stochastic processes are shown to satisfy the strong mixing condition with random instants of sampling. With the analysis presented, we provide a novel analytic tool for studying the departure process in a general queueing model.

    Full Text Available Allogeneic stem cell transplantation (allo-SCT is a curative therapy for different life-threatening malignant and nonmalignant hematologic disorders. Graft-versus-host disease (GVHD remains a major source of morbidity and mortality following allo-SCT, which limits the use of this treatment in a broader spectrum of patients. Early diagnostic of GVHD is essential to initiate treatment as soon as possible. Unfortunately, the diagnosis of GVHD may be difficult to establish, because of the nonspecific nature of the associated symptoms and of the numerous differential diagnosis. This is particularly true regarding gastrointestinal (GI acute GVHD. In the recent years many progress has been made in medical imaging test and endoscopic techniques. The interest of these different techniques in the diagnosis of GI acute GVHD has been evaluated in several studies. With this background we review the contributions, limitations, and future prospect of these techniques in the diagnosis of GI acute GVHD.

    2015-07-20

    We introduce redMaGiC, an automated algorithm for selecting Luminous Red Galaxies (LRGs). The algorithm was developed to minimize photometric redshift uncertainties in photometric large-scale structure studies. redMaGiC achieves this by self-training the color-cuts necessary to produce a luminosity-thresholded LRG sam- ple of constant comoving density. Additionally, we demonstrate that redMaGiC photo-zs are very nearly as accurate as the best machine-learning based methods, yet they require minimal spectroscopic training, do not suffer from extrapolation biases, and are very nearly Gaussian. We apply our algorithm to Dark Energy Survey (DES) Science Verification (SV) data to produce a redMaGiC catalog sampling the redshift range z ϵ [0.2,0.8]. Our fiducial sample has a comoving space density of 10-3 (h-1Mpc)-3, and a median photo-z bias (zspec zphoto) and scatter (σz=(1 + z)) of 0.005 and 0.017 respectively.The corresponding 5σ outlier fraction is 1.4%. We also test our algorithm with Sloan Digital Sky Survey (SDSS) Data Release 8 (DR8) and Stripe 82 data, and discuss how spectroscopic training can be used to control photo-z biases at the 0.1% level.

    We derive Debye series expansion (DSE) for infinitely long multilayered cylinders normally incident by shaped beam. Typically the interaction between multilayered cylinders and Gaussian beam is derived in detail, and localized approximation is introduced to calculate the beam shaped coefficients. Finally DSE is employed to the study of rainbow scattering by graded-index polymer optical fiber (GI-POF).

    2009-04-01

    This paper is devoted to the study on measurement of refractive index profile of graded-index polymer optical fiber (GI-POF) by light scattering. Using Generalized Airy theory and Debye series of an inhomogeneous cylinder, the scattering intensity distributions are obtained of Airy structure of rainbows for different refractive index profile. The results show that positions of Airy peaks depend closely on refractive index profile of GI-POF. Since each order of rainbow penetrates it to different depths, such methods could be used to provide information of the refractive index profile of GI-POF. For GI-POF with given diameter, positions of Airy peaks of rainbows are simulated as a function of refractive index profile, which can be used to inverse unknown parameters of refractive index profile. The least square method is used in inversion of refractive index profile with the given refractive index of the cladding. The results obtained agree with theoretical values with high precision. The method has the advantages of non-instructive and on-line measurement, and can be used for the measurement of other inhomogeneous droplets.

    Full Text Available BACKGROUND: Bacteriocins are antimicrobial peptides that are produced by bacteria as a defense mechanism in complex environments. Identification and characterization of novel bacteriocins in novel strains of bacteria is one of the important fields in bacteriology. METHODOLOGY/FINDINGS: The strain GI-9 was identified as Brevibacillus sp. by 16 S rRNA gene sequence analysis. The bacteriocin produced by strain GI-9, namely, laterosporulin was purified from supernatant of the culture grown under optimal conditions using hydrophobic interaction chromatography and reverse-phase HPLC. The bacteriocin was active against a wide range of Gram-positive and Gram-negative bacteria. MALDI-TOF experiments determined the precise molecular mass of the peptide to be of 5.6 kDa and N-terminal sequencing of the thermo-stable peptide revealed low similarity with existing antimicrobial peptides. The putative open reading frame (ORF encoding laterosporulin and its surrounding genomic region was fished out from the draft genome sequence of GI-9. Sequence analysis of the putative bacteriocin gene did not show significant similarity to any reported bacteriocin producing genes in database. CONCLUSIONS: We have identified a bacteriocin producing strain GI-9, belonging to the genus Brevibacillus sp. Biochemical and genomic characterization of laterosporulin suggests it as a novel bacteriocin with broad spectrum antibacterial activity.

    2000-12-01

    Despite advancements in endoscopy and pharmacology in the treatment of peptic ulcer disease the overall mortality has remained constant at 10% for the past four decades. The aim of this study was to determine the age, gender, racial distribution, incidence and causes of endoscopically diagnosed cases of upper gastrointestinal (UGI) bleeding to summarise treatments undertaken and to report their outcome. A prospective study of UGI bleeding in 128 patients was performed in two surgical wards of Kuala Lumpur Hospital, involving both elective and emergency admissions. The study group comprised of 113 (88.2%) males and 15 (11.7%) females. The mean age was 51.9 years (range 14 to 85 years) and 37.5% (48 of 128 patients) were older than 60 years. The Indian race was over-represented in all disease categories. Smoking (50.1%), alcohol consumption (37.5%), non-steroidal anti-inflammatory drugs (NSAIDs) (17.2%), traditional remedies (5.5%), anti-coagulants (2.3%) and steroids (0.8%) were among the risk factors reported. Common presenting symptoms and signs included malaena (68.8%), haematemesis (59.4%) and fresh per rectal bleeding (33.6%). The commonest causes of UGI bleeding were duodenal ulcer (32%), gastric ulcer (29.7%), erosions (duodenal and gastric) (21.9%), oesophageal varices (10.9%) and malignancy (3.9%). UGI bleeding was treated non-surgically in 90.6% of cases. Blood transfusions were required in 62.6% (67/107) of peptic ulcer disease patients. Surgical intervention for bleeding peptic ulcer occurred in around 10% of cases and involved under-running of the bleeding vessel in most high risk duodenal and gastric ulcer patients. The overall mortality from bleeding peptic ulcer disease was 4.7%. Six patients died from torrential UGI haemorrhage soon after presentation, without the establishment of a cause. Active resuscitative protocols, early endoscopy, more aggressive interventional therapy, early surgery by more senior surgeons, increasing intensive care unit

    Full Text Available Abstract Background A bleeding pseudoaneurysm in patients with chronic pancreatitis is a rare and potentially lethal complication. Optimal treatment of bleeding peripancreatic pseudoaneurysm remains controversial. This study reports on experience at Chang Gung Memorial Hospital (CGMH in managing of bleeding pseudoaneurysms associated with chronic pancreatitis. Methods The medical records of 9 patients (8 males and 1 female; age range, 28 – 71 years; median, 36 years with bleeding pseudoaneurysms associated with chronic pancreatitis treated at CGMH between Aug. 1992 and Sep. 2004 were retrospectively reviewed. Alcohol abuse (n = 7;78% was the predominant predisposing factor. Diagnoses of bleeding pseudoaneurysms were based on angiographic (7/7, computed tomographic (4/7, ultrasound (2/5, and surgical (2/2 findings. Whether surgery or angiographic embolization was performed was primarily based on patient clinical condition. Median follow-up was 38 months (range, 4 – 87 months. Results Abdominal computed tomography revealed bleeding pseudoaneurysms in 4 of 7 patients (57%. Angiography determined correct diagnosis in 7 patients (7/7, 100%. The splenic artery was involved in 5 cases, the pancreaticoduodenal artery in 2, the gastroduodenal artery in 1, and the middle colic artery in 1. Initial treatment was emergency (n = 4 or elective (n = 3 surgery in 7 patients and arterial embolization in 2. Rebleeding was detected after initial treatment in 3 patients. Overall, 5 arterial embolizations and 9 surgical interventions were performed; the respective rates of success of these treatments were 20% (1/5 and 89% (8/9. Five patients developed pseudocysts before treatment (n = 3 or following intervention (n = 2. Pseudocyst formation was identified in 2 of the 3 rebleeding patients. Five patients underwent surgical treatment for associated pseudocysts and bleeding did not recur. One patient died from angiography-related complications. Overall mortality

    AIM: To investigate the endoscopic hemostasis for gastrointestinal bleeding due to Dieulafoy's lesion. METHODS: One hundred and seven patients with gastrointestinal bleeding due to Dieulafoy's lesion were treated with three endoscopic hemostasis methods: aethoxysklerol injection (46 cases), endoscopic hemoclip hemostasis (31 cases), and a combination of hemoclip hemostasis with aethoxysklerol injection (30 cases). RESULTS: The rates of successful hemostasis using the three methods were 71.7% (33/46), 77.4% (24/31) and 96.7% (29/30), respectively, with significant differences between the methods (P < 0.05). Among those who had unsuccessful treatment with aethoxysklerol injection, 13 were treated with hemoclip hemostasis and 4 underwent surgical operation; 9 cases were successful in the injection therapy. Among the cases with unsuccessful treatment with hemoclip hemostasis, 7 were treated with injection of aethoxysklerol and 3 cases underwent surgical operation; 4 cases were successful in the treatment with hemoclip hemostasis. Only 1 case had unsuccessful treatment with a combined therapy of hemoclip hemostasis and aethoxysklerol injection, and surgery was then performed. No serious complications of perforation occurred in the patients whose bleeding was treated with the endoscopic hemostasis, and no re-bleeding was found during a 1-year follow-up. CONCLUSION: The combined therapy of hemoclip hemostasis with aethoxysklerol injection is the most effective method for gastrointestinal bleeding due to Dieulafoy's lesion.

    Dabigatran, a direct thrombin inhibitor, is increasingly used for stroke prevention in patients with non-valvular atrial fibrillation. Dabigatran has a stable pharmacokinetic profile with minimum drug interactions, and requires no routine laboratory evaluation to measure level of anticoagulation. This provides a huge advantage over warfarin, and has the potential to improve patient compliance. The disadvantages of dabigatran are the lack of a reversal agent to counter dabigatran-related bleeding and the absence of a widely available laboratory test that can quantify the extent of coagulopathy in dabigatran overdose. Hemodialysis can rapidly lower dabigatran levels and assist in controlling bleeding secondary to dabigatran overdose. However, in cases in which hemodynamic instability precludes the use of hemodialysis, alternative methods have to be utilized to control dabigatran-associated bleeding. Here we document a case of massive gastrointestinal bleeding secondary to dabigatran use that was successfully managed by continuous venovenous hemodialysis (CVVHD), along with supportive care with blood product transfusions. CVVHD reduces thrombin time and activated partial thrombin time, and causes a parallel decrease in amount of active bleeding. Finally, we show that compared to the rapid lowering of elevated thrombin time observed in hemodialysis, CVVHD requires several days to reduce thrombin time to normal range. PMID:25633777

    Traditional methods for trait phenotyping have been a bottleneck for research in many crop species due to their intensive labor, high cost, complex implementation, lack of reproducibility and propensity to subjective bias. Recently, multiple high-throughput phenotyping platforms have been developed, but most of them are expensive, species-dependent, complex to use, and available only for major crops. To overcome such limitations, we present the open-source software GiNA, which is a simple and free tool for measuring horticultural traits such as shape- and color-related parameters of fruits, vegetables, and seeds. GiNA is multiplatform software available in both R and MATLAB® programming languages and uses conventional images from digital cameras with minimal requirements. It can process up to 11 different horticultural morphological traits such as length, width, two-dimensional area, volume, projected skin, surface area, RGB color, among other parameters. Different validation tests produced highly consistent results under different lighting conditions and camera setups making GiNA a very reliable platform for high-throughput phenotyping. In addition, five-fold cross validation between manually generated and GiNA measurements for length and width in cranberry fruits were 0.97 and 0.92. In addition, the same strategy yielded prediction accuracies above 0.83 for color estimates produced from images of cranberries analyzed with GiNA compared to total anthocyanin content (TAcy) of the same fruits measured with the standard methodology of the industry. Our platform provides a scalable, easy-to-use and affordable tool for massive acquisition of phenotypic data of fruits, seeds, and vegetables. PMID:27529547

    Femoral neuropathy occurs when occult retroperitoneal bleeding impinges on the appropriate nerve roots. The syndrome involves the acute onset of groin and thigh pain with characteristic flexion and external rotation of the hip. It may mimic other conditions such as acute arterial occlusion. Thorough knowledge of the anatomy of the femoral nerve explains the clinical features and leads the clinician to suspect the occurrence of this syndrome. Three cases have been reviewed that exhibited this condition as a result of retroperitoneal bleeding, a complication of systemic heparin therapy. The hemophilia that afflicted Alexis, the Crown Prince of Russia and son of Tsar Nicholas and Tsarina Alexandra, resulted in this clinical syndrome. The consequences enabled the sinister starets, Gregory Rasputin, to become intimately involved with the royal family, influencing the response of the Tsar to the political events in Russia, thereby playing an important role in setting the stage for the 1917 Russian communist revolution.

    2014-01-01

    Obscure gastrointestinal bleeding(OGIB) is defined as recurrent or persistent bleeding or presence of iron deficiency anaemia after evaluation with a negative bidirectional endoscopy. OGIB accounts for 5% of gastrointestinal bleeding and presents a diagnostic challenge. Current modalities available for the investigation of OGIB include capsule endoscopy, balloon assisted enteroscopy, spiral enteroscopy and computed tomography enterography. These modalities overcome the limitations of previous techniques. Following a negative bidirectional endoscopy, capsule endoscopy and double balloon enteroscopy remain the cornerstone of investigation in OGIB given their high diagnostic yield. Longterm outcome data in patients with OGIB is limited, but is most promising for capsule endoscopy. This article reviews the current literature and provides an overview of the clinical evaluation of patients with OGIB, available diagnostic and therapeutic modalities and longterm clinical outcomes.

    1980-01-01

    It is noted that a significant fuel savings can be achieved by reducing bleed air used for cabin air conditioning. Air in the cabin can be recirculated to maintain comfortable ventilation rates but the quality of the air tends to decrease due to entrainment of smoke and odors. Attention is given to a development system designed and fabricated under the NASA Engine Component Improvement Program to define the recirculation limit for the DC-10. It is shown that with the system, a wide range of bleed air reductions and recirculation rates is possible. A goal of 0.8% fuel savings has been achieved which results from a 50% reduction in bleed extraction from the engine.

  20. PALM-COEIN Nomenclature for Abnormal Uterine Bleeding.

    2016-05-01

    Approximately 30% of women will experience abnormal uterine bleeding (AUB) during their life time. Previous terms defining AUB have been confusing and imprecisely applied. As a consequence, both clinical management and research on this common problem have been negatively impacted. In 2011, the International Federation of Gynecology and Obstetrics (FIGO) Menstrual Disorders Group (FMDG) published PALM-COEIN, a new classification system for abnormal bleeding in the reproductive years. Terms such as menorrhagia, menometrorrhagia, metrorrhagia, dysfunctional uterine bleeding, polymenorrhea, oligomenorrhea, and uterine hemorrhage are no longer recommended. The PALM-COEIN system was developed to standardize nomenclature to describe the etiology and severity of AUB. A brief description of the PALM-COEIN nomenclature is presented as well as treatment options for each etiology. Clinicians will frequently encounter women with AUB and should report findings utilizing the PALM-COEIN system. PMID:26969858

    2016-04-01

    The impact of venous thromboembolism (VTE) in the cancer population remains substantial despite significant advances in detecting and treating thrombotic events. While there is extensive literature regarding predictors of first VTE event in cancer patients as well as a validated predictive score, less data exist regarding recurrent VTE in cancer cohorts and associated predictive variables. A similar paucity of data in regard to bleeding events in cancer patients receiving anticoagulation has been observed. This review article will highlight clinical risk factors as well as predictive biomarkers associated with recurrent VTE and bleeding in cancer patients receiving therapeutic anticoagulation. Predictive risk assessment models for cancer-associated recurrent VTE and bleeding are also discussed. PMID:27067987

    Purpose: Radiation-induced gastric bleeding has been poorly understood. In this study, we described dosimetric predictors for gastric bleeding after fractionated radiation therapy. Methods and Materials: The records of 139 sequential patients treated with 3-dimensional conformal radiation therapy (3D-CRT) for intrahepatic malignancies were reviewed. Median follow-up was 7.4 months. The parameters of a Lyman normal tissue complication probability (NTCP) model for the occurrence of {>=}grade 3 gastric bleed, adjusted for cirrhosis, were fitted to the data. The principle of maximum likelihood was used to estimate parameters for NTCP models. Results: Sixteen of 116 evaluable patients (14%) developed gastric bleeds at a median time of 4.0 months (mean, 6.5 months; range, 2.1-28.3 months) following completion of RT. The median and mean maximum doses to the stomach were 61 and 63 Gy (range, 46-86 Gy), respectively, after biocorrection of each part of the 3D dose distributions to equivalent 2-Gy daily fractions. The Lyman NTCP model with parameters adjusted for cirrhosis predicted gastric bleed. Best-fit Lyman NTCP model parameters were n=0.10 and m=0.21 and with TD{sub 50} (normal) = 56 Gy and TD{sub 50} (cirrhosis) = 22 Gy. The low n value is consistent with the importance of maximum dose; a lower TD{sub 50} value for the cirrhosis patients points out their greater sensitivity. Conclusions: This study demonstrates that the Lyman NTCP model has utility for predicting gastric bleeding and that the presence of cirrhosis greatly increases this risk. These findings should facilitate the design of future clinical trials involving high-dose upper abdominal radiation.

    Two patients with gynaecological hemorrhage underwent successfully trans-arterial embolization. The first womanhad an uncontrollable perineal hemorrhage following a delivery with forceps. Angiography showed extravasation of contrast from right and left vaginal artery. Hyperselective embolisation stopped the vaginal bleeding. The second woman had massive hemorrhage following radiotherapy for cervical cancer. Angiography demonstrated extravasation of contrast from both uterine arteries. The bleeding was controlled after hyperselective embolisation. Emergency arterial embolisation is a safe and effective means of control of irrepressible genital hemorrhage. PMID:16238279

    This is a case report of a gastric lipoma causing a severe upper gastrointestinal bleeding. About 200 cases of this very rare benign gastric tumor have been reported so far. Symptoms are not characteristic, but may also mimic malignancy when occurring with bleeding, obstruction or weight loss. Malignant transformation is possible, but extremely rare. Because the tumor is situated under the submucosal layer in 90%, preoperative diagnosis by endoscopic biopsy is almost never possible. The tumor has to be treated by resection. A diagnosis by frozen section during the operation is recommended.

    Two patients with massive gastrointestinal bleeding are reported. One bled from an aneurysm of a branch of the left hepatic artery, the blood reaching the bowel through communication with the biliary tree. The second had an aneurysm of a branch of the splenic artery which communicated with the pancreatic duct. This type of bleeding is intermittent and, consequently, actual extravasation of contrast media is not always seen. Therefore, if one sees an aneurysm of a visceral artery, even if it does not directly supply the enteric tract, one should consider the possibility that it is the origin of the hemorrhage. Pathogenesis, diagnostic modalities, and therapeutic implications are discussed. PMID:1083037

    Full Text Available Abstract Introduction Henoch-Schönlein purpura is the most common systemic vasculitis in children. Typical presentations are palpable purpura, abdominal pain, arthritis, and hematuria. This vasculitic syndrome can present as an uncommon cause of rectal bleeding in older patients. We report a case of an older man with Henoch-Schönlein purpura. He presented with rectal bleeding and acute kidney injury secondary to IgA mesangioproliferative glomerulonephritis. Case presentation A 75-year-old Polish man with a history of diverticulosis presented with a five-day history of rectal bleeding. He had first noticed colicky left lower abdominal pain two months previously. At that time he was treated with a 10-day course of ciprofloxacin and metronidazole for possible diverticulitis. He subsequently presented with rectal bleeding to our emergency department. Physical examination revealed generalized palpable purpuric rash and tenderness on his left lower abdomen. Laboratory testing showed a mildly elevated serum creatinine of 1.3. Computed tomography of his abdomen revealed a diffusely edematous and thickened sigmoid colon. Flexible sigmoidoscopy showed severe petechiae throughout the colon. Colonic biopsy showed small vessel acute inflammation. Skin biopsy resulted in a diagnosis of leukocytoclastic vasculitis. Due to worsening kidney function, microscopic hematuria and new onset proteinuria, he underwent a kidney biopsy which demonstrated IgA mesangioproliferative glomerulonephritis. A diagnosis of Henoch-Schönlein purpura was made. Intravenous methylprednisolone was initially started and transitioned to prednisone tapering orally to complete six months of therapy. There was marked improvement of abdominal pain. Skin lesions gradually faded and gastrointestinal bleeding stopped. Acute kidney injury also improved. Conclusion Henoch-Schönlein purpura, an uncommon vasculitic syndrome in older patients, can present with lower gastrointestinal bleeding

    We describe our experience with the use of N-butyl cyanoacrylate (NBCA) embolization of abdominal wall bleeding and we evaluate the clinical effectiveness of the procedure. Embolization was performed in nine patients with abdominal wall bleeding. The sites of embolization were the left first lumbar (n = 1), left second lumbar (n = 1), right inferior epigastric (n 2), left inferior epigastric (n = 3), right circumflex iliac (n = 1), and left circumflex iliac artery (n = 1). A coil was used with NBCA in one patient due to difficulty in selecting only a bleeding focus and anticipated reflux. NBCA was mixed with Lipiodol at the ratio of 1:1 to 1:4. Blood pressure and heart rate were measured before and after the embolization procedure, and the serial hemoglobin and hematocrit levels and transfusion requirements were reviewed to evaluate hemostasis and rebleeding. Hemostasis was obtained in six out of the nine patients and technical success was achieved in all patients. There were no procedure-related complications. Four out of the nine patients died due to rebleeding of a subarachnoid hemorrhage (n = 1), multiorgan failure (n = 1), and hepatic failure (n =2) that occurred two to nine days after the embolization procedure. One patient had rebleeding. The five surviving patients had no rebleeding, and the patients continue to visit the clinical on an outpatient basis. NBCA embolization is a clinically safe procedure and is effective for abdominal wall bleeding.
