ObjectiveThis study was designed to evaluate the role of a negative computed tomography angiogram (CTA) in patients who present with gastrointestinal (GI) hemorrhage.MethodsA review of all patients who had CTAs for GI hemorrhage over an 8-year period from January 2005 to December 2012 was performed. Data for patient demographics, location of hemorrhage, hemodynamic stability, and details of angiograms and/or the embolization procedure were obtained from the CRIS/PACS database, interventional radiology database, secure electronic medical records, and patient’s clinical notes.ResultsA total of 180 patients had 202 CTAs during the 8-year period: 87 CTAs were performed for upper GI hemorrhage (18 positivemore » for active bleeding, 69 negative) and 115 for lower GI hemorrhage (37 positive for active bleeding, 78 negative); 58.7 % (37/63) of patients with upper GI bleed and 77.4 % (48/62) of patients with lower GI bleed who had an initial negative CTA did not rebleed without the need for radiological or surgical intervention. This difference was statistically significant (p = 0.04). The relative risk of rebleeding, following a negative CTA, in lower GI bleeding versus upper GI bleeding patients is 0.55 (95 % confidence interval 0.32–0.95).ConclusionsPatients with upper GI bleed who had negative CTAs usually require further intervention to stop the bleeding. In contrast, most patients presenting with lower GI hemorrhage who had a negative first CTA were less likely to rebleed.« less

To distinguish upper from lower gastrointestinal (GI) bleeding. Patient records between April 2011 and March 2014 were analyzed retrospectively (3296 upper endoscopy, and 1520 colonoscopy). Seventy-six patients had upper GI bleeding (Upper group) and 65 had lower GI bleeding (Lower group). Variables were compared between the groups using one-way analysis of variance. Logistic regression was performed to identify variables significantly associated with the diagnosis of upper vs lower GI bleeding. Receiver-operator characteristic (ROC) analysis was performed to determine the threshold value that could distinguish upper from lower GI bleeding. Hemoglobin (P = 0.023), total protein (P = 0.0002), and lactate dehydrogenase (P = 0.009) were significantly lower in the Upper group than in the Lower group. Blood urea nitrogen (BUN) was higher in the Upper group than in the Lower group (P = 0.0065). Logistic regression analysis revealed that BUN was most strongly associated with the diagnosis of upper vs lower GI bleeding. ROC analysis revealed a threshold BUN value of 21.0 mg/dL, with a specificity of 93.0%. The threshold BUN value for distinguishing upper from lower GI bleeding was 21.0 mg/dL.

In the last few years, the number of anticoagulated patients has significantly increased and, as a consequence, so have hemorrhagic complications due to this therapy. We analyzed gastrointestinal (GI) bleeding because it is the most frequent type of major bleeding in these patients, and we hypothesized that they would have lesions responsible for GI bleeding regardless of the intensity of anticoagulation, although excessively anticoagulated patients would have more serious hemorrhages. To study the characteristics of anticoagulated patients with GI bleeding and the relationship between the degree of anticoagulation and a finding of causative lesions and bleeding severity. We prospectively studied 96 patients, all anticoagulated with acenocoumarol and consecutively admitted to hospital between 01/01/2003 and 09/30/2005 because of acute GI bleeding. We excluded patients with severe liver disease, as well as nine patients with incomplete details. The incidence of GI bleeding requiring hospitalization was 19.6 cases/100,000 inhabitants-year. In 90% of patients, we found a causative (85% of upper GI bleeding and 50% of lower GI bleeding) or potentially causative lesion, and 30% of them required endoscopic treatment, without differences depending on the intensity of anticoagulation. No relationship was found between the type of lesions observed and the degree of anticoagulation in these patients. Patients who received more intense anticoagulation therapy had more severe hemorrhages (23% of patients with an INR ≥4 had a life-threatening bleed versus only 4% of patients with INR <4). We found an incidence of 20 severe GI bleeding episodes in anticoagulated patients per 100,000 inhabitants-year, with no difference in localization or in the frequency of causative lesions depending on the intensity of anticoagulation. Patients receiving more intense anticoagulation had more severe GI bleeding episodes. Copyright © 2013 Elsevier España, S.L. and AEEH y AEG. All rights reserved.

Modern left ventricular assist devices (LVAD) require anti-coagulation (AC) with warfarin and anti-platelet therapy to prevent thromboembolic complications in patients. Gastrointestinal bleeding (GI) is a significant adverse event in these patients and treatment typically requires reduction or elimination of AC or anti-platelet therapy. It is not known whether alterations in AC to treat GI bleeding influence subsequent risk of thromboembolic (TE) events during LVAD support. Between July 2003 and September 2011, 389 patients (308 male) underwent implantation of a continuous-flow LVAD at the University of Michigan Health System and the Mayo Clinic. Median age at implant was 60 years (range 18 to 79 years). Outcomes were analyzed for the association of GI bleeding events and subsequent TE events, defined as stroke, transient ischemic attack, hemolysis or suspected or confirmed pump thrombosis. Median survival was 10 months (maximum 7.2 years, total 439 patient-years). TE events occurring within the first 30 days were not counted. Overall survival and freedom from an outcome event were assessed using the Kaplan-Meier method. Associations between GI bleeding and subsequent TE events and survival impact were analyzed as time-dependent covariates. One hundred ninety-nine GI bleeding episodes occurred in 116 of 389 patients (30%) for an event rate of 0.45 GI bleed/patient-year of support. One hundred thirty-eight TE events occurred in 97 of 389 patients (25%) for an event rate of 0.31 TE event/patient-year of support. Median time from LVAD implant to first GI bleed was 5 months (range 1 to 116 months) and to first TE event was 6 months (range 1 to 29 months). For patients who had a TE event after GI bleed, the median interval was 5 months (range 0.5 to 25 months). TE events were 7.4-fold more likely in patients who had a prior GI bleed (range 4.9- to 11.1-fold) (p < 0.001); however, neither the presence of GI bleeding (0.7 to 1.2) nor a TE event (0.8 to 2.0) portended a lower overall survival. Patients who had GI bleeding were at significantly higher risk for a subsequent TE event. Although the exact cause of this relationship is unknown, it suggests that a reduction in anti-coagulation and anti-platelet management to treat GI bleeds may contribute to this risk.

Acute lower gastrointestinal bleeding is a major problem worldwide, being a rare and life threatening condition, with a mortality rate situated between 2 and 4%. Acute lower gastrointestinal bleeding is solvent for 1 - 2% of the entire hospital emergencies, 15% presenting as massive bleeding and up to 5% requiring surgery. Lower gastrointestinal bleeding can be classified depending on their location in the small or large intestine. The small bowel is the rarest site of lower gastrointestinal bleeding, at the same time being the commonest cause of obscure bleeding. 5% of total lower GI bleeding appears in the small bowel. When endoscopic therapy associated with medical treatment are insufficient, endovascular intervention can be lifesaving. Unfortunately in some rare cases of acute lower gastrointestinal bleeding with hemo-dynamic instability and the angiography performed being unable to locate the source of bleeding, the last therapeutic resource remains surgery. In the following we exemplify two cases of acute lower gastrointestinal bleeding which were resolved in different ways, followed by a thorough description of the different types of available treatment and finally, in the conclusions, we systematize the most important stages of the management algorithm in acute lower gastrointestinal bleeding.

Impaired kidney function is a risk factor for upper gastrointestinal (GI) bleeding, an event associated with poor outcomes. The burden of upper GI bleeding and its effect on patients with ESRD are not well described. Using data from the US Renal Data System, we quantified the rates of occurrence of and associated 30-day mortality from acute, nonvariceal upper GI bleeding in patients undergoing dialysis; we used medical claims and previously validated algorithms where available. Overall, 948,345 patients contributed 2,296,323 patient-years for study. The occurrence rates for upper GI bleeding were 57 and 328 episodes per 1000 person-years according to stringent and lenient definitions of acute, nonvariceal upper GI bleeding, respectively. Unadjusted occurrence rates remained flat (stringent) or increased (lenient) from 1997 to 2008; after adjustment for sociodemographic characteristics and comorbid conditions, however, we found a significant decline for both definitions (linear approximation, 2.7% and 1.5% per year, respectively; P<0.001). In more recent years, patients had higher hematocrit levels before upper GI bleeding episodes and were more likely to receive blood transfusions during an episode. Overall 30-day mortality was 11.8%, which declined significantly over time (relative declines of 2.3% or 2.8% per year for the stringent and lenient definitions, respectively). In summary, despite declining trends worldwide, crude rates of acute, nonvariceal upper GI bleeding among patients undergoing dialysis have not decreased in the past 10 years. Although 30-day mortality related to upper GI bleeding declined, perhaps reflecting improvements in medical care, the burden on the ESRD population remains substantial. PMID:22266666

It is not clear whether use of low-dose aspirin should be resumed after an episode of lower gastrointestinal (GI) bleeding. We assessed the long-term risks of recurrent lower GI bleeding and serious cardiovascular outcomes after aspirin-associated lower GI bleeding. We performed a retrospective study of patients diagnosed with lower GI bleeding (documented melena or hematochezia and absence of upper GI bleeding) from January 1, 2000 through December 31, 2007 at the Prince of Wales Hospital in Hong Kong. Using the hospital registry, we analyzed data from 295 patients on aspirin and determined their outcomes during a 5-year period. Outcomes included recurrent lower GI bleeding, serious cardiovascular events, and death from other causes, as determined by an independent, blinded adjudication committee. Outcomes were compared between patients assigned to the following groups based on cumulative duration of aspirin use: <20% of the follow-up period (121 nonusers) vs ≥50% of the observation period (174 aspirin users). Within 5 years, lower GI bleeding recurred in 18.9% of aspirin users (95% confidence interval [CI], 13.3%-25.3%) vs 6.9% of nonusers (95% CI, 3.2%-12.5%; P = .007). However, serious cardiovascular events occurred in 22.8% of aspirin users (95% CI, 16.6%-29.6%) vs 36.5% of nonusers (95% CI, 27.4%-45.6%; P = .017), and 8.2% of aspirin users died from other causes (95% CI, 4.6%-13.2%) vs 26.7% of nonusers (95% CI, 18.7%-35.4%; P = .001). Multivariable analysis showed that aspirin use was an independent predictor of rebleeding, but protected against cardiovascular events and death. Among aspirin users with a history of lower GI bleeding, continuation of aspirin is associated with an increased risk of recurrent lower GI bleeding, but reduced risk of serious cardiovascular events and death.

AIM: To determine the value of computed tomographic angiography (CTA) for diagnosis and therapeutic planning in lower gastrointestinal (GI) bleeding. METHODS: Sixty-three consecutive patients with acute lower GI bleeding underwent CTA before endovascular or surgical treatment. CTA was used to determine whether the lower GI bleeding was suitable for endovascular treatment, surgical resection, or conservative treatment in each patient. Treatment planning with CTA was compared with actual treatment decisions or endovascular or surgical treatment that had been carried out in each patient based on CTA findings. RESULTS: 64-row CTA detected active extravasation of contrast material in 57 patients and six patients had no demonstrable active bleeding, resulting in an accuracy of 90.5% in the detection of acute GI bleeding (57 of 63). In three of the six patients with no demonstrable active bleeding, active lower GI bleeding recurred within one week after CTA, and angiography revealed acute bleeding. The overall location-based accuracy, sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) for the detection of GI bleeding by 64-row CTA were 98.8% (249 of 252), 95.0% (57 of 60), 100% (192 of 192), 100% (57 of 57), and 98.5% (192 of 195), respectively. Treatment planning was correctly established on the basis of 64-row CTA with an accuracy, sensitivity, specificity, PPV and NPV of 98.4% (248 of 252), 93.3% (56 of 60), 100% (192 of 192), 100% (56 of 56), and 97.5% (192 of 196), respectively, in a location-based evaluation. CONCLUSION: 64-row CTA is safe and effective in making decisions regarding treatment, without performing digital subtraction angiography or surgery, in the majority of patients with lower GI bleeding.

Recurrent gastrointestinal bleeding is one of the most challenging complications encountered in the management of patients with von Willebrand disease (VWD). The commonest cause is angiodysplasia, but often no cause is identified due to the difficulty in making the diagnosis. The optimal treatment to prevent recurrences remains unknown. We performed a retrospective study of VWD patients with occult or angiodysplastic bleeding within the setting of the von Willebrand Disease Prophylaxis Network (VWD PN) to describe diagnostic and treatment strategies. Centres participating in the VWD PN recruited subjects under their care with a history of congenital VWD and gastrointestinal (GI) bleeding due to angiodysplasia, or cases in which the cause was not identified despite investigation. Patients with acquired von Willebrand syndrome or those for whom the GI bleeding was due to another cause were excluded. Forty-eight patients from 18 centres in 10 countries were recruited. Seven individuals had a family history of GI bleeding and all VWD types except 2N were represented. Angiodysplasia was confirmed in 38%, with video capsule endoscopy and GI tract endoscopies being the most common methods of making the diagnosis. Recurrent GI bleeding in VWD is associated with significant morbidity and required hospital admission on up to 30 occasions. Patients were treated with multiple pharmacological agents with prophylactic von Willebrand factor concentrate being the most efficient in preventing recurrence of the GI bleeding. The diagnosis and treatment of recurrent GI bleeding in congenital VWD remains challenging and is associated with significant morbidity. Prophylactic treatment with von Willebrand factor concentrate was the most effective method of preventing recurrent bleeding but its efficacy remains to be confirmed in a prospective study. © 2014 John Wiley & Sons Ltd.

There is emerging concern that selective serotonin reuptake inhibitors (SSRIs) may be associated with an increased risk of upper gastrointestinal (GI) bleeding, and that this risk may be further increased by concurrent use of nonsteroidal anti-inflammatory (NSAID) medications. Previous reviews of a relatively small number of studies have reported a substantial risk of upper GI bleeding with SSRIs; however, more recent studies have produced variable results. The objective of this study was to obtain a more precise estimate of the risk of upper GI bleeding with SSRIs, with or without concurrent NSAID use. MEDLINE, EMBASE, PsycINFO, the Cochrane central register of controlled trials (through April 2013), and US and European conference proceedings were searched. Controlled trials, cohort, case-control, and cross-sectional studies that reported the incidence of upper GI bleeding in adults on SSRIs with or without concurrent NSAID use, compared with placebo or no treatment were included. Data were extracted independently by two authors. Dichotomous data were pooled to obtain odds ratio (OR) of the risk of upper GI bleeding with SSRIs +/- NSAID, with a 95% confidence interval (CI). The main outcome and measure of the study was the risk of upper GI bleeding with SSRIs compared with placebo or no treatment. Fifteen case-control studies (including 393,268 participants) and four cohort studies were included in the analysis. There was an increased risk of upper GI bleeding with SSRI medications in the case-control studies (OR=1.66, 95% CI=1.44,1.92) and cohort studies (OR=1.68, 95% CI=1.13,2.50). The number needed to harm for upper GI bleeding with SSRI treatment in a low-risk population was 3,177, and in a high-risk population it was 881. The risk of upper GI bleeding was further increased with the use of both SSRI and NSAID medications (OR=4.25, 95% CI=2.82,6.42). SSRI medications are associated with a modest increase in the risk of upper GI bleeding, which is lower than has previously been estimated. This risk is significantly elevated when SSRI medications are used in combination with NSAIDs, and physicians prescribing these medications together should exercise caution and discuss this risk with patients.

Gastrointestinal (GI) bleeding is a leading cause of death in dengue. This study aims to identify predictors for GI bleeding in adult dengue patients, emphasizing the impact of existing comorbid disease(s). Of 1300 adults with dengue virus infection, 175 (mean age, 56.5±13.7 years) patients with GI bleeding and 1,125 (mean age, 49.2±15.6 years) without GI bleeding (controls) were retrospectively analyzed. Among 175 patients with GI bleeding, dengue hemorrhagic fever was found in 119 (68%) patients; the median duration from onset dengue illness to GI bleeding was 5 days. Gastric ulcer, erythematous gastritis, duodenal ulcer, erosive gastritis, and hemorrhagic gastritis were found in 52.3%, 33.3%, 28.6%, 28.6%, and 14.3% of 42 patients with GI bleeding who had undergone endoscopic examination, respectively. Overall, nine of the 175 patients with GI bleeding died, giving an in-hospital mortality rate of 5.1%. Multivariate analysis showed age ≥60 years (cases vs. controls: 48% vs. 28.3%) (odds ratio [OR]: 1.663, 95% confidence interval [CI]: 1.128-2.453), end stage renal disease with additional comorbidities (cases vs. controls: 1.7% vs. 0.2%) (OR: 9.405, 95% CI: 1.4-63.198), previous stroke with additional comorbidities (cases vs. controls: 7.4% vs. 0.6%) (OR: 9.772, 95% CI: 3.302-28.918), gum bleeding (cases vs. controls: 27.4% vs. 11.5%) (OR: 1.732, 95% CI: 1.1-2.727), petechiae (cases vs. controls: 56.6% vs. 29.1%) (OR: 2.109, 95% CI: 1.411-3.153), and platelet count <50×109 cells/L (cases vs. controls: 53.1% vs. 25.8%) (OR: 3.419, 95% CI: 2.103-5.558) were independent predictors of GI bleeding in patients with dengue virus infection. Our study is the first to disclose that end stage renal disease and previous stroke, with additional comorbidities, were strongly significant associated with the risk of GI bleeding in patients with dengue virus infection. Identification of these risk factors can be incorporated into the patient assessment and management protocol of dengue virus infection to reduce its mortality.

Background The development of gastrointestinal (GI) bleeding and end-stage renal disease (ESRD) can be a concern in the management of Henoch–Schönlein purpura (HSP). We aimed to evaluate whether the neutrophil-to-lymphocyte ratio (NLR) is associated with the prognosis of adult patients with HSP. Methods Clinical data including the NLR of adult patients with HSP were retrospectively analyzed. Patients were classified into three groups as follows: (a) simple recovery, (b) wax & wane without GI bleeding, and (c) development of GI bleeding. The optimal cut-off value was determined using a receiver operating characteristics curve and the Youden index. Results A total of 66 adult patients were enrolled. The NLR was higher in the GI bleeding group than in the simple recovery or wax & wane group (simple recovery vs. wax & wane vs. GI bleeding; median [IQR], 2.32 [1.61–3.11] vs. 3.18 [2.16–3.71] vs. 7.52 [4.91–10.23], P<0.001). For the purpose of predicting simple recovery, the optimal cut-off value of NLR was 3.18, and the sensitivity and specificity were 74.1% and 75.0%, respectively. For predicting development of GI bleeding, the optimal cut-off value was 3.90 and the sensitivity and specificity were 87.5% and 88.6%, respectively. Conclusions The NLR is useful for predicting development of GI bleeding as well as simple recovery without symptom relapse. Two different cut-off values of NLR, 3.18 for predicting an easy recovery without symptom relapse and 3.90 for predicting GI bleeding can be used in adult patients with HSP. PMID:27073884

Upper gastrointestinal (GI) bleeding is a common medical emergency associated with significant morbidity and mortality. The clinical presentation depends on the amount and location of hemorrhage and the endoscopic profile varies according to different etiology. At present, there are limited epidemiological data on upper GI bleed and associated mortality from India, especially in the middle and elderly age group, which has a higher incidence and mortality from this disease. This study aims to study the clinical and endoscopic profile of middle aged and elderly patients suffering from upper GI bleed to know the etiology of the disease and outcome of the intervention. Out of a total of 1790 patients who presented to the hospital from May 2015 to August 2017 with upper GI bleed, and underwent upper GI endoscopy, data of 1270 patients, aged 40 years and above, was compiled and analyzed retrospectively. All the patients included in the study were above 40 years of age. Majority of the patients were males, with a male to female ratio of 1.6:1. The most common causes of upper GI bleed in these patients were portal hypertension-related (esophageal, gastric and duodenal varices, portal hypertensive gastropathy, and gastric antral vascular ectasia GAVE), seen in 53.62% of patients, followed by peptic ulcer disease (gastric and duodenal ulcers) seen in 17.56% of patients. Gastric erosions/gastritis accounted for 15.20%, and duodenal erosions were seen in 5.8% of upper GI bleeds. The in-hospital mortality rate in our study population was 5.83%. The present study reported portal hypertension as the most common cause of upper GI bleeding, while the most common endoscopic lesions reported were esophageal varices, followed by gastric erosion/gastritis, and duodenal ulcer.

Bleeding originating in the gastrointestinal (GI) tract is one of the most common adverse events after left ventricular assist device (LVAD) implantation. In these patients, GI bleeding appears to be the consequence of altered hemostasis on the one hand and alterations of the GI microvasculature on the other. We report the case of a patient who suffered repeated, severe GI bleeding early after implantation of a HeartMate II continuous-flow LVAD. After failure of conventional treatment strategies, GI bleeding was controlled using repeated transfusions of a purified von Willebrand factor (VWF) concentrate, almost devoid of Factor VIII (Wilfactin, LFB). No episodes of pump thrombosis were noted. Subsequent to VWF transfusions, we observed a progressive normalization of circulating vascular endothelial growth factor levels. Our data raise the possibility that, in addition to its hemostatic properties, transfusions of VWF might have acted as an antiangiogenic factor. © 2014 AABB.

Aspirin is one of the most widely used medication for its analgesic and anti-platelet properties and thus a major cause for gastrointestinal (GI) bleeding. This study compared the preventive effect of histamine-2 receptor antagonists (H2RAs) and proton-pump inhibitors (PPIs) against chronic low-dose aspirin (LDA)-related GI bleeding and ulcer formation. Electronic databases of Pubmed, Embase and Cochrane Central Register of Controlled Trials were searched for human observations (randomised controlled trials and observational studies) comparing the long term effects of PPIs and H2RAs treatment in the prevention of GI bleeding or ulcer formation in patients on chronic LDA treatment listed up till September 30, 2016. Two independent authors searched databases using PICO questions (aspirin, H2RA, PPI, GI bleeding or ulcer), and reviewed abstracts and articles for comprehensive studies keeping adequate study quality. Data of weighted odds ratios were statistically evaluated using Comprehensive Metaanalysis (Biostat, Inc., Engelwood, MJ, USA), potential bias was checked. Nine studies for GI bleeding and eight studies for ulcer formation were found meeting inclusion criteria, altogether 1,879 patients were included into review. The H2RAs prevented less effectively LDA-related GI bleeding (OR= 2.102, 95% CI: 1.008-4.385, p<0.048) and ulcer formation (OR= 2.257, 95% CI: 1.277-3.989, p<0.005) than PPIs. The meta-analysis showed that H2RAs were less effective in the prevention of LDA-related GI bleeding and ulcer formation suggesting the preferable usage of PPIs in case of tolerance.

Angiodysplasia (AD) of the gastrointestinal (GI) tract is a rare cause of surgical GI bleeding. It frequently poses difficult problems in diagnosis and treatment. The purpose of this study is to find answers to these problems for a better management of the AD patients. From 1982 to 2006 a total of 75 patients suffering of AD of the GI tract were operated in our center. They represent about 3.6% of total patients operated for GI bleeding in the same period. The age of the patients was between 9 and 81 years old, with two peaks: one between 21 and 40 years old and the other between 51 and 70 years old. The localisation of the lesions was: righ colon +/- ileum 31 patients (41.33%), stomach 13 patients (17.33%), jejunum 6 patients (8%), descendent colon +/- sigmoid 5 patients (6.66%), rectum 4 patients (5.33%), pan-colonic 4 patients (5.33%), sigmoid colon 2 patients (2.66%), cecum + transverse colon 2 patients (2.66%), ileum 2 patients (2.66%), sigmoid colon + jejunum 1 patient (1.33%), cecum + sigmoid colon 1 patient (1.33%), cecum +/- sigmoid colon + jejunum 1 patient (1.33%), jejunum + ileum 1 patient (1.33%), pan-colonic + rectum 1 patient (1.33%). According to Moore classifications 29 patients were type 1 (38%) and 45 patients were type 2 (60%). In one patient AD was associated with Crohn disease (type 4 Fowler). The main symptom in AD was repetitive GI bleeding, of various amplitude, often obscure in origin, the patients having many hospital entries. The medical examination that give us the best help was selective angiography which was positive in 34 of 40 patients (85%). Upper and lower endoscopy were give to 50 surgical patients, being diagnostic in 32 (64%). Histopathologic examinations confirm the diagnosis of AD in all cases, without using injection techniques. All patients were operated for symptomatic AD. Other 11 patients non included in this study were find to have angiodysplastic lesions on operatory specimens for other diseases. The main indications for operative in AD were: continuing digestive hemorrhage of growing amplitude with detected source (54 patients = 72%), inefficient endoscopic and angiographic hemostasis (8 patients = 10.66%) and patients with massive bleeding without any preoperative evaluation (13 patients = 17%). Intraoperative exploration produced little information because of the mucosal and submucosal localisation of the lesions. Operative panendoscopy was the most rewarding investigation. Various types of resections were practiced depending on the site(s) known or presumed of the lesions. Perioperative morbidity was 23% (21 patients), rebleeding being in 4 patients (5.33%). Perioperative mortality was 12% (9 patients) a consequence of advanced age, comorbid conditions and frequent extreme emergency of the operations. Although rare as a cause of surgical digestive bleeding, AD poses often difficult problems of diagnosis and treatment. In patients with GI bleeding, without evident cause, multiple investigated, especially elderly but not always, we must think of an AD.

Purpose of StudyTo identify the remediable factors in the quality of care provided to patients with severe gastrointestinal (GI) bleeding.MethodAll hospital admissions in the first four months of 2013 with ICD10 coding for GI bleeding who received a transfusion of 4 units or more of blood. Up to five cases/hospital randomly selected for structured case note peer review. National availability of GI bleeding services data derived from organisational questionnaire completed by all hospitals.Results4563/29,796 (15.3%) of GI bleeds received 4 or more units of blood with a mortality rate of 20.2% compared to 7.3% without blood transfusion. 30.8% of GI bleedsmore » received a blood transfusion. 32% (60/185) of hospitals admitting acute GI bleeds lacked 24/7 endoscopy. 26% (48/185) had on-site embolisation 24/7 with a further 34% (64/185) accessing embolisation by transfer within a validated formal network. Blood product use was inappropriate in 20% (84/426). Improved management, principally earlier senior gastroenterologist review and/or endoscopy, would have reduced blood product use in 25% (113/457). 14.5% (90/618) had a CT scan which identified the site of bleeding in 32% (29/90). 7.8% (36/459) underwent an Interventional Radiology (IR) procedure but a further 6.3% (21/33) should have had IR. 6% (36/586) underwent surgery with 21/36 for uncontrolled bleeding. In 20/35 IR was not considered despite the majority being suitable for IR. Overall 44% (210/476) received an acceptable standard of care according to peer review.Conclusions26 recommendations were made to improve the quality of care in GI bleeding, with six principle recommendations.« less

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.

Upper gastrointestinal bleeding - state of the art.

Upper gastrointestinal (GI) bleeding is a condition requiring immediate medical intervention, with high associated mortality exceeding 10%. The most common cause of upper GI bleeding is peptic ulcer disease, which largely corresponds to the intake of NSAIDs and Helicobacter pylori infection. Endoscopy is the essential tool for the diagnosis and treatment of active upper GI hemorrhage. Endoscopic therapy together with proton pump inhibitors and eradication of Helicobacter pylori significantly reduces rebleeding rates, mortality and number of emergency surgical interventions. This paper presents contemporary data on the diagnosis and treatment of upper gastrointestinal bleeding.

Dabigatran etexilate, was found to be effective for stroke prevention in patients with non-valvular atrial fibrillation. Given its predictable pharmacodynamics, laboratory monitoring is not required. Moreover, the risks of overall bleeding, intracranial bleeding, and life-threatening hemorrhage from dabigatran were found to be lower than warfarin. However, a higher risk of gastrointestinal (GI) bleeding caused by dabigatran from the randomized evaluation of long-term anticoagulant therapy (RE-LY) trial has raised the concern regarding clinical outcomes of patients with GI bleeding caused by dabigatran compared with warfarin. We retrospectively studied patients who were hospitalized for GI bleeding from dabigatran compared with warfarin with therapeutic anticoagulation monitoring during 2009 to 2012. Initial laboratory findings at presentation, number of transfused packed red blood cells (PRBCs), acute kidney injury, clinical outcomes (e.g., hypotension, tachycardia), length of stay, and death were compared. Thirteen patients taking dabigatran and 26 patients who were on warfarin with therapeutic international normalized ratio (INR) were hospitalized during the study period. Demographic data and baseline parameters between the two groups were not significantly different except for concurrent aspirin use (84.6% vs. 50%, P=0.036). Fifty-four percent of patients taking dabigatran did not have activated partial thromboplastin time (aPTT) level performed at presentation (7/13). The patients with GI bleeding from warfarin received significantly more PRBC transfusions compared with the dabigatran group (1.92±2.2 vs. 0.69±1.1 units, P=0.024). After controlling for initial hemoglobin and history of chronic kidney disease by using multivariate analysis, the patients in the warfarin group were likely to receive more PRBC. Hypotension at presentation was more common in GI bleeding caused by warfarin than dabigatran but the P value was insignificant (30.8% vs. 7.7%, P=0.11). Nevertheless, no differences in clinical outcomes or length of stay were found between the two groups. From our data, the patients with GI bleeding from dabigatran were likely to receive fewer PRBC transfusions; however, clinical outcomes and length of stay were comparable to GI bleeding caused by warfarin. Our sample generalizes to an elderly population (mean age of 77.9±10 years old) with creatinine clearance (CrCl) >30 mL/min who experience GI bleeding during chronic anticoagulation.

It is not clear whether H 2 -receptor antagonists (H2RAs) reduce the risk of gastrointestinal (GI) bleeding in aspirin users at high risk. We performed a double-blind randomized trial to compare the effects of a proton pump inhibitor (PPI) vs a H2RA antagonist in preventing recurrent upper GI bleeding and ulcers in high-risk aspirin users. We studied 270 users of low-dose aspirin (≤325 mg/day) with a history of endoscopically confirmed ulcer bleeding at 8 sites in Hong Kong and Japan. After healing of ulcers, subjects with negative results from tests for Helicobacter pylori resumed aspirin (80 mg) daily and were assigned randomly to groups given a once-daily PPI (rabeprazole, 20 mg; n = 138) or H2RA (famotidine, 40 mg; n = 132) for up to 12 months. Subjects were evaluated every 2 months; endoscopy was repeated if they developed symptoms of upper GI bleeding or had a reduction in hemoglobin level greater than 2 g/dL and after 12 months of follow-up evaluation. The adequacy of upper GI protection was assessed by end points of recurrent upper GI bleeding and a composite of recurrent upper GI bleeding or recurrent endoscopic ulcers at month 12. During the 12-month study period, upper GI bleeding recurred in 1 patient receiving rabeprazole (0.7%; 95% confidence interval [CI], 0.1%-5.1%) and in 4 patients receiving famotidine (3.1%; 95% CI, 1.2%-8.1%) (P = .16). The composite end point of recurrent bleeding or endoscopic ulcers at month 12 was reached by 9 patients receiving rabeprazole (7.9%; 95% CI, 4.2%-14.7%) and 13 patients receiving famotidine (12.4%; 95% CI, 7.4%-20.4%) (P = .26). In a randomized controlled trial of users of low-dose aspirin at risk for recurrent GI bleeding, a slightly lower proportion of patients receiving a PPI along with aspirin developed recurrent bleeding or ulcer than of patients receiving an H2RA with the aspirin, although this difference was not statistically significant.

Non-steroidal anti-inflammatory drug related upper gastrointestinal bleeding: types of drug use and patient profiles in real clinical practice.

Sostres, Carlos; Carrera-Lasfuentes, Patrica; Lanas, Angel

2017-10-01

The best available evidence regarding non-steroidal anti-inflammatory drug (NSAID)-related gastrointestinal (GI) bleeding comes from randomized controlled trials including patients who use NSAIDs to manage chronic rheumatic diseases; however, patients with varying background profiles commonly take NSAIDs for many other reasons, often without prescription, and such usage has not been well studied. To define the characteristics of patients hospitalized for upper GI bleeding in clinical practice, we conducted a case-control study among patients with endoscopy-proven major upper GI bleeding due to gastroduodenal peptic lesions and control subjects. We used adjusted logistic regression models to estimate bleeding risks. Data analysis was performed using SPSS 22.0. Our analysis included 3785 cases and 6540 controls, including 1270 cases (33.55%) and 834 controls (12.75%) reporting recent use (<30 days) of NSAIDs including high-dose acetylsalicylic acid (ASA). NSAID use was associated with increased risk of upper GI bleeding, with an adjusted relative risk of 4.86 (95% CI, 4.32-5.46). Acute musculoskeletal pain (36.1%), chronic osteoarthritis (13.5%), and headache (13.6%) were the most common reasons for NSAID use. Among cases, only 17.31% took NSAIDs and 6.38% took high dose ASA due to chronic osteoarthritis. Demographic characteristics significantly differed between subjects with chronic vs. acute musculoskeletal pain. Proton pump inhibitor use was significantly higher in patients who used NSAIDs due to chronic osteoarthritis compared to patients with acute musculoskeletal pain. NSAID (65.15%) or high-dose ASA use (65.83%) preceding upper GI bleeding was most often short-term. In over half of cases (63.62%), the upper GI bleeding event was not preceded by dyspeptic warning symptoms. The majority of patients hospitalized due to NSAID-related upper GI bleeding reported short-term NSAID use for reasons other than chronic rheumatic disease. These findings suggest that current prevention strategies may not reach a wide population of short-term NSAID users.

In this paper, we present a novel and clinically valuable software platform for automatic bleeding detection on gastrointestinal (GI) tract from Capsule Endoscopy (CE) videos. Typical CE videos for GI tract run about 8 hours and are manually reviewed by physicians to locate diseases such as bleedings and polyps. As a result, the process is time consuming and is prone to disease miss-finding. While researchers have made efforts to automate this process, however, no clinically acceptable software is available on the marketplace today. Working with our collaborators, we have developed a clinically viable software platform called GISentinel for fully automated GI tract bleeding detection and classification. Major functional modules of the SW include: the innovative graph based NCut segmentation algorithm, the unique feature selection and validation method (e.g. illumination invariant features, color independent features, and symmetrical texture features), and the cascade SVM classification for handling various GI tract scenes (e.g. normal tissue, food particles, bubbles, fluid, and specular reflection). Initial evaluation results on the SW have shown zero bleeding instance miss-finding rate and 4.03% false alarm rate. This work is part of our innovative 2D/3D based GI tract disease detection software platform. While the overall SW framework is designed for intelligent finding and classification of major GI tract diseases such as bleeding, ulcer, and polyp from the CE videos, this paper will focus on the automatic bleeding detection functional module.

Upper gastrointestinal (GI) bleeding remains a commonly encountered diagnosis for acute care surgeons. Initial stabilization and resuscitation of patients is imperative. Stable patients can have initiation of medical therapy and localization of the bleeding, whereas persistently unstable patients require emergent endoscopic or operative intervention. Minimally invasive techniques have surpassed surgery as the treatment of choice for most upper GI bleeding. Copyright © 2014 Elsevier Inc. All rights reserved.

Novel Use of Thalidomide in Recurrent Gastrointestinal Tract Bleeding in Patients with Left Ventricular Assist Devices: A Case Series.

Bleeding is an important and common complication of left ventricular assist devices (LVADs). One of the common causes of gastrointestinal bleeding is arteriovenous malformations. However, the source of bleeding is often hard to identify. Thalidomide is efficacious in treatment of gastrointestinal (GI) bleeding in non-LVAD patients. We report our experience of the use of thalidomide in the treatment of GI bleeding in four patients with LVAD. Four patients who had recurrent GI bleeding from May 2009 to December 2014 were started on thalidomide. All of them responded to treatment and had no further gastrointestinal bleeding while on thalidomide. One patient developed constipation, requiring thalidomide to be stopped. Another patient developed symptomatic neuropathy, that resolved with reduction of dosage. Thalidomide appears safe and efficacious in LVAD patients with recurrent gastrointestinal bleeding.

Placement of self-expandable nitinol stents is useful for the treatment of esophageal and upper gastrointestinal (GI) obstruction. However, complications such as stent migration, tumor overgrowth, and bleeding occur. Although stent migration and tumor overgrowth are well documented in previous studies, the occurrence of bleeding has not been fully evaluated. To evaluate the incidence, management strategies, and predictors of bleeding after placement of self-expandable nitinol stents in patients with esophageal and upper GI obstruction. We retrospectively reviewed the medical records and results of computed tomography and endoscopy of 1485 consecutive patients with esophageal and upper GI obstructions who underwent fluoroscopically guided stent placement. Bleeding occurred in 25 of 1485 (1.7%) patients 0 to 348 days after stent placement. Early stent-related bleeding occurred in 10 patients (40%) and angiographic embolization was used for 5/10. Late bleeding occurred in 15 patients (60%) and endoscopic hemostasis was used for 7/15. Twenty-two of 25 (88%) patients with bleeding had received prior radiotherapy and/or chemotherapy. Bleeding is a rare complication after placement of expandable nitinol stents in patients with esophageal and upper GI obstruction, but patients with early bleeding may require embolization for control. Care must be exercised on placing stents in patients who have received prior radiotherapy or chemotherapy. © The Foundation Acta Radiologica 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

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.

It has recently been shown that statins increase the myocardial content of prostaglandin (PG) I2 (prostacyclin) and PGE2. A systemic increase of PG production may protect the gastric mucosa and prevent gastrointestinal (GI) bleeding. We hypothesized that statins would lower the risk of GI bleeding associated with antiplatelet therapy in patients with acute coronary syndromes (ACS). We retrospectively analyzed data on 10288 patients with ACS included in the OPUS-TIMI 16 trial and received aspirin and either the oral IIb/IIIa inhibitor orbofiban or placebo. Inhospital GI bleeding rate was significantly lower in patients who were receiving lipid-lowering drugs before admission compared with those who were not (0.2% vs 0.6%, P = .031). Throughout 10 months of follow-up, GI bleeding occurred in 1.8% of non-statin users compared with 1.0% of statin users (P = .001). Statin use was associated with less overall bleeding in both the orbofiban (1.4% vs 2.4%, P = .006) and the placebo groups (0.2% vs 0.8%, P = .047). Severe and major bleeding occurred less frequently with statin use (0.8% vs 1.5%, P = .001) in both the orbofiban (1.1% vs 2.0%, P = .006) and the placebo groups (0.1% vs 0.5%, P = .119). Logistic regression analysis showed that age > 65 years, orbofiban treatment, Killip class > 1, history of cerebrovascular disease, and calcium-channel blocker use were associated with higher risk of GI bleeding, whereas statin therapy was associated with a lower risk (odds ratio 0.68, 95% CI 0.45-1.04, P = .079). Statins may exert protective effect against GI bleeding in patients with ACS. Additional studies are warranted to explore this additional potential benefit of statins.

To investigate the efficacy and clinical outcome of patients treated with an over-the-scope-clip (OTSC) system for severe gastrointestinal hemorrhage, perforations and fistulas. From 02-2009 to 10-2012, 84 patients were treated with 101 OTSC clips. 41 patients (48.8%) presented with severe upper-gastrointestinal (GI) bleeding, 3 (3.6%) patients with lower-GI bleeding, 7 patients (8.3%) underwent perforation closure, 18 patients (21.4%) had prevention of secondary perforation, 12 patients (14.3%) had control of secondary bleeding after endoscopic mucosal resection or endoscopic submucosal dissection (ESD) and 3 patients (3.6%) had an intervention on a chronic fistula. In 78/84 patients (92.8%), primary treatment with the OTSC was technically successful. Clinical primary success was achieved in 75/84 patients (89.28%). The overall mortality in the study patients was 11/84 (13.1%) and was seen in patients with life-threatening upper GI hemorrhage. There was no mortality in any other treatment group. In detail OTSC application lead to a clinical success in 35/41 (85.36%) patients with upper GI bleeding and in 3/3 patients with lower GI bleeding. Technical success of perforation closure was 100% while clinical success was seen in 4/7 cases (57.14%) due to attendant circumstances unrelated to the OTSC. Technical and clinic success was achieved in 18/18 (100%) patients for the prevention of bleeding or perforation after endoscopic mucosal resection and ESD and in 3/3 cases of fistula closure. Two application-related complications were seen (2%). This largest single center experience published so far confirms the value of the OTSC for GI emergencies and complications. Further clinical experience will help to identify optimal indications for its targeted and prophylactic use.

Acute upper gastrointestinal (GI) bleeding is a common medical emergency. A common risk factor of upper GI bleeding is cirrhosis of liver, which can lead to variceal haemorrhage. 30-40% of cirrhotic patients who bleed may have non-variceal upper GI bleeding and it is frequently caused by peptic ulcers, portal gastropathy, Mallory-Weiss tear, and gastroduodenal erosions. The objective of this study was to determine the frequency of upper gastrointestinal endoscopic findings among patients presenting with upper gastrointestinal bleeding with liver cirrhosis. This descriptive cross-sectional study was carried out in Gastroenterology & Hepatology Department of Ayub Teaching Hospital, Abbottabad from February 2012 to June 2013. 252 patients diagnosed with cirrhosis, presenting with upper GI bleed, age 50 years of either gender, and were included in the study. Non-probability consecutive sampling was used, Endoscopy was performed on each patient and the findings documented. The mean age was 57.84 +/- 6.29 years. There were 158 (62.7%) males and 94 (37.3%) females. The most common endoscopic finding was oesophageal varices (92.9%, n=234) followed by portal hypertensive gastropathy (38.9%, n=98) with almost equal distribution among males and females. Gastric varices were found in 33.3% of patients (n=84). Among other non-variceal lesions, peptic ulcer disease was seen in 26 patients (10.3%) while gastric erosions were found in 8 patients (3.2%). In patients with acute upper GI bleeding and liver cirrhosis, the most common endoscopic finding is oesophageal varices, with a substantially higher value in our part of the country, apart from other non-variceal causes.

Roux-en-Y gastric bypass (RYGBP) is the most commonly performed bariatric operation in the USA. In the early postoperative stage, gastrointestinal (GI) bleeding is an infrequent but potentially serious complication that usually results from bleeding at the gastrojejunostomy staple-line. Observant management with transfusion for stable patients and surgical exploration for unstable patients is typically recommended for early GI bleeding. We hypothesized that use of endoclips, which do not cause thermal injury to the surrounding tissues (or anastomosis), may be preferable to thermal approaches which could cause tissue injury. We report 2 cases of early GI bleeding after RYGBP that were successfully managed with endoclip application to bleeding lesions. Emergent endoscopy was performed, and major stigmata such as active spurting vessel and adherent clot were noted at the gastrojejunostomy staple-lines. Endoscopic hemostasis using endoclips was readily applied to bleeding lesions at staple-lines. Primary hemostasis was achieved, and there was no recurrent bleeding or complication. We conclude that therapeutic endoscopy can be performed safely for early bleeding after RYGBP. In patients with early bleeding after RYGBP, use of endoclips is mechanistically preferable to other options.

Haemosuccus pancreaticus, an uncommon cause of upper gastro intestinal bleeding: Case report and review of the literature.

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

Background Aspirin has been shown to lower the incidence and the mortality of vascular disease and cancer but its wider adoption appears to be seriously impeded by concerns about gastrointestinal (GI) bleeding. Unlike heart attacks, stroke and cancer, GI bleeding is an acute event, usually followed by complete recovery. We propose therefore that a more appropriate evaluation of the risk-benefit balance would be based on fatal adverse events, rather than on the incidence of bleeding. We therefore present a literature search and meta-analysis to ascertain fatal events attributable to low-dose aspirin. Methods In a systematic literature review we identified reports of randomised controlled trials of aspirin in which both total GI bleeding events and bleeds that led to death had been reported. Principal investigators of studies in which fatal events had not been adequately described were contacted via email and asked for further details. A meta-analyses was then performed to estimate the risk of fatal gastrointestinal bleeding attributable to low-dose aspirin. Results Eleven randomised trials were identified in the literature search. In these the relative risk (RR) of ‘major’ incident GI bleeding in subjects who had been randomised to low-dose aspirin was 1.55 (95% CI 1.33, 1.83), and the risk of a bleed attributable to aspirin being fatal was 0.45 (95% CI 0.25, 0.80). In all the subjects randomised to aspirin, compared with those randomised not to receive aspirin, there was no significant increase in the risk of a fatal bleed (RR 0.77; 95% CI 0.41, 1.43). Conclusions The majority of the adverse events caused by aspirin are GI bleeds, and there appears to be no valid evidence that the overall frequency of fatal GI bleeds is increased by aspirin. The substantive risk for prophylactic aspirin is therefore cerebral haemorrhage which can be fatal or severely disabling, with an estimated risk of one death and one disabling stroke for every 1,000 people taking aspirin for ten years. These adverse effects of aspirin should be weighed against the reductions in vascular disease and cancer. PMID:27846246

To determine the preventive effect and safety of proton pump inhibitors (PPIs) in low-dose aspirin (LDA)-associated gastrointestinal (GI) ulcers and bleeding. We searched MEDLINE, EMBASE and the Cochrane Controlled Trials Register from inception to December 2013, and checked conference abstracts of randomized controlled trials (RCTs) on the effect of PPIs in reducing adverse GI events (hemorrhage, ulcer, perforation, or obstruction) in patients taking LDA. The preventive effects of PPIs were compared with the control group [taking placebo, a cytoprotective agent, or an H2 receptor antagonist (H2RA)] in LDA-associated upper GI injuries. The meta-analysis was performed using RevMan 5.1 software. We evaluated 8780 participants in 10 RCTs. The meta-analysis showed that PPIs decreased the risk of LDA-associated upper GI ulcers (OR = 0.16; 95%CI: 0.12-0.23) and bleeding (OR = 0.27; 95%CI: 0.16-0.43) compared with control. For patients treated with dual anti-platelet therapy of LDA and clopidogrel, PPIs were able to prevent the LDA-associated GI bleeding (OR = 0.36; 95%CI: 0.15-0.87) without increasing the risk of major adverse cardiovascular events (MACE) (OR = 1.00; 95%CI: 0.76-1.31). PPIs were superior to H2RA in prevention of LDA-associated GI ulcers (OR = 0.12; 95%CI: 0.02-0.65) and bleeding (OR = 0.32; 95%CI: 0.13-0.79). PPIs are effective in preventing LDA-associated upper GI ulcers and bleeding. Concomitant use of PPI, LDA and clopidogrel did not increase the risk of MACE.

To evaluate the initial management of upper gastrointestinal (GI) bleeding in the United States. Various guidelines have addressed the initial management of upper GI bleeding, but the extent to which these guidelines are followed in clinical practice is unknown. We conducted a national survey of emergency physicians, internists, and gastroenterologists practicing in hospitals affiliated with an ACGME-accredited gastroenterology fellowship. Participants rated their agreement and adherence to 9 preendoscopic quality indicators for the initial management of upper GI bleeding. Awareness, use, and barriers to the use of early prognostic risk scores were also assessed. A total of 1402 surveys were completed, with an estimated response rate of 11.3%. Gastroenterologists and trainees agreed with the quality indicators more than nongastroenterologists and attending physicians, respectively. There was no difference in the application of the quality indicators by specialty or clinical position. Among all physicians, 53% had ever heard of and 30% had ever used an upper GI bleeding risk score. More gastroenterologists than nongastroenterologists had heard of (82% vs. 44%, P<0.001) and used (51% vs. 23%, P<0.001) a risk score. There was no difference between attending physicians and trainees. Gastroenterologists and attending physicians more often cited lack of utility as a reason to not use risk scores, whereas nongastroenterologists and trainees more often cited lack of knowledge. Among emergency physicians, internists, and gastroenterologists in the United States, agreement with upper GI bleeding initial management guidelines was high but adherence--especially pertaining to the use of risk scores--was low.

ACG Clinical Guideline: Diagnosis and Management of Small Bowel Bleeding.

Gerson, Lauren B; Fidler, Jeff L; Cave, David R; Leighton, Jonathan A

2015-09-01

Bleeding from the small intestine remains a relatively uncommon event, accounting for ~5-10% of all patients presenting with gastrointestinal (GI) bleeding. Given advances in small bowel imaging with video capsule endoscopy (VCE), deep enteroscopy, and radiographic imaging, the cause of bleeding in the small bowel can now be identified in most patients. The term small bowel bleeding is therefore proposed as a replacement for the previous classification of obscure GI bleeding (OGIB). We recommend that the term OGIB should be reserved for patients in whom a source of bleeding cannot be identified anywhere in the GI tract. A source of small bowel bleeding should be considered in patients with GI bleeding after performance of a normal upper and lower endoscopic examination. Second-look examinations using upper endoscopy, push enteroscopy, and/or colonoscopy can be performed if indicated before small bowel evaluation. VCE should be considered a first-line procedure for small bowel investigation. Any method of deep enteroscopy can be used when endoscopic evaluation and therapy are required. VCE should be performed before deep enteroscopy if there is no contraindication. Computed tomographic enterography should be performed in patients with suspected obstruction before VCE or after negative VCE examinations. When there is acute overt hemorrhage in the unstable patient, angiography should be performed emergently. In patients with occult hemorrhage or stable patients with active overt bleeding, multiphasic computed tomography should be performed after VCE or CTE to identify the source of bleeding and to guide further management. If a source of bleeding is identified in the small bowel that is associated with significant ongoing anemia and/or active bleeding, the patient should be managed with endoscopic therapy. Conservative management is recommended for patients without a source found after small bowel investigation, whereas repeat diagnostic investigations are recommended for patients with initial negative small bowel evaluations and ongoing overt or occult bleeding.

Exsanguinating upper GI bleeds due to Unusual Arteriovenous Malformation (AVM) of stomach and spleen: a case report.

In this paper we are reporting one case of exsanguinating upper gastrointestinal tract (GIT) bleed requiring massive blood transfusion and immediate life saving surgery. A 30 years old female, 12 weeks pregnant was referred to our hospital from the earth-quake affected area of Kashmir with history of upper abdominal pain, haematemesis and melaena for one week. After stabilizing the patient, upper gastro-intestinal endoscopy was performed. It revealed gastric ulcer just distal to the gastro-esophageal junction on the lesser curvature. Biopsy from the ulcer edge led to profuse spurting of the blood and patient went into state of shock. Immediate resuscitation led to rebleeding and recurrence of post haemorrahagic shock. The patient was immediately explored and total gastrectectomy with splenectomy concluded as life saving procedure. A review of literature was conducted to make this report possible.

To determine the incidence and severity of bleeding events requiring hospitalization among patients with atrial fibrillation (AF) receiving anticoagulants (dabigatran or warfarin) or antiplatelet agents (eg, aspirin and clopidogrel). This was a single-center, retrospective cohort study involving 1494 patients with AF hospitalized from November 1, 2010, to November 1, 2011, with prior warfarin, dabigatran, or antiplatelet therapy. Overall bleeding events in the dabigatran group compared to the warfarin group were 24% and 12%, respectively ( P = .004). Of these events, individually, there were no significant differences in major (56% vs 58%, P = .88), life-threatening (25% vs 36%, P = .38), or minor bleeding (44% vs 42%, P = .06). Gastrointestinal (GI) bleeding occurred more in the dabigatran group compared to the warfarin group ( P = .02). Intracranial bleeding occurred in 15% of patients in the warfarin group and did not occur at all in the dabigatran group. Warfarin patients had significantly more overall bleeding events compared to antiplatelet therapy ( P < .001), with an increasing trend seen in major bleeding ( P = .06). GI bleeding, however, favored the warfarin group over the antiplatelet group (48% vs 73%, P = .04). Anticoagulation with dabigatran was associated with an overall increased occurrence of bleeding requiring hospital admission compared to warfarin. GI bleeding was more prevalent with dabigatran and antiplatelets than with warfarin. There were more intracranial hemorrhages seen in the warfarin group.

Background Low-dose aspirin has proven effectiveness in secondary and primary prevention of cardiovascular events, but is also associated with an increased risk of major bleeding events. For primary prevention, this absolute risk must be carefully weighed against the benefits of aspirin; such assessments are currently limited by a lack of data from general populations. Methods Systematic searches of Medline and Embase were conducted to identify observational studies published between 1946 and 4 March 2015 that reported the risks of gastrointestinal (GI) bleeding or intracranial hemorrhage (ICH) with long-term, low-dose aspirin (75–325 mg/day). Pooled estimates of the relative risk (RR) for bleeding events with aspirin versus non-use were calculated using random-effects models, based on reported estimates of RR (including odds ratios, hazard ratios, incidence rate ratios and standardized incidence ratios) in 39 articles. Findings The incidence of GI bleeding with low-dose aspirin was 0.48–3.64 cases per 1000 person-years, and the overall pooled estimate of the RR with low-dose aspirin was 1.4 (95% confidence interval [CI]: 1.2–1.7). For upper and lower GI bleeding, the RRs with low-dose aspirin were 2.3 (2.0–2.6) and 1.8 (1.1–3.0), respectively. Neither aspirin dose nor duration of use had consistent effects on RRs for upper GI bleeding. The estimated RR for ICH with low-dose aspirin was 1.4 (1.2–1.7) overall. Aspirin was associated with increased bleeding risks when combined with non-steroidal anti-inflammatory drugs, clopidogrel and selective serotonin reuptake inhibitors compared with monotherapy. By contrast, concomitant use of proton pump inhibitors decreased upper GI bleeding risks relative to aspirin monotherapy. Conclusions The risks of major bleeding with low-dose aspirin in real-world settings are of a similar magnitude to those reported in randomized trials. These data will help inform clinical judgements regarding the use of low-dose aspirin in prevention of cardiovascular events. PMID:27490468

To evaluate the effectiveness of transcatheter arterial embolization (TAE) for gastrointestinal (GI) bleeding caused by GI lymphoma. The medical records of 11 patients who underwent TAE for GI bleeding caused by GI lymphoma between 2001 and 2015 were reviewed retrospectively. A total of 20 TAE procedures were performed. On angiography, contrast extravasation, and both contrast extravasation and tumor staining were seen in 95 % (19/20) and 5 % (1/20) of the procedures, respectively. The most frequently embolized arteries were jejunal (n = 13) and ileal (n = 5) branches. Technical and clinical success rates were 100 % (20/20) and 27 % (3/11), respectively. The causes of clinical failure in eight patients were rebleeding at new sites. In four patients who underwent repeat angiography, the bleeding focus was new each time. Three patients underwent small bowel resection due to rebleeding after one (n = 2) or four (n = 1) times of TAEs. Another two patients underwent small bowel resection due to small bowel ischemia/perforation after three or four times of TAEs. The 30-day mortality rate was 18 % due to hypovolemic shock (n = 1) and multiorgan failure (n = 1). Angiogram with TAE shows limited therapeutic efficacy to manage GI lymphoma-related bleeding due to high rebleeding at new sites. Although TAE can be an initial hemostatic measure, surgery should be considered for rebleeding due to possible bowel ischemic complication after repeated TAE procedures.

Gastrointestinal Bleeding Following LVAD Placement from Top to Bottom.

2016-06-01

Left ventricular assist devices (LVADs) are an increasingly prevalent form of mechanical support for patients with end-stage heart failure. These devices can be implanted both as a bridge to transplant and as definitive/destination therapy. Gastrointestinal (GI) bleeding is one of the most common and recalcitrant long-term complications following LVAD implantation, with an incidence approaching 30 %. This review will discuss what is known about the pathophysiology of GI bleeding in LVADs and the currently available options for medical and/or endoscopic management. The pathophysiology of bleeding is multifactorial, with hemodynamic alterations, acquired von Willebrand factor deficiency, and coagulopathy being most often implicated. The majority of bleeding events in this population result from angioectasias and gastroduodenal erosive disease. While these bleeding events are significant and often require transfusion therapy, they are rarely life threatening. Endoscopy remains the standard of care with upper endoscopy offering the highest diagnostic yield in these patients. However, the effectiveness of endoscopic hemostasis in this population is not well established. A small number of studies have evaluated medical therapy and alterations in LVAD settings as a means of preventing or treating bleeding with variable results. In summary, GI bleeding with LVADs is a common occurrence and will continue to be as more LVADs are being performed for destination therapy.

Luo, Xuefeng; Nie, Ling; Wang, Zhu

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 pancreatitismore » 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.« less

To assess the efficacy and safety of esomeprazole in preventing upper gastrointestinal (GI) bleeding in critically ill Chinese patients, using cimetidine as an active comparator. A pre-specified non-inferiority limit (5%) was used to compare rates of significant upper GI bleeding in this randomized, double-blind, parallel-group, phase 3 study across 27 intensive care units in China. Secondary endpoints included safety and tolerability measures. Patients required mechanical ventilation and had at least one additional risk factor for stress ulcer bleeding. Patients were randomized to receive either active esomeprazole 40 mg, as a 30-min intravenous (IV) infusion twice daily, and an IV placebo cimetidine infusion or active cimetidine 50 mg/h, as a continuous infusion following an initial bolus of 300 mg, and placebo esomeprazole injections, given up to 14 days. Patients were blinded using this double-dummy technique. Of 274 patients, 2.7% with esomeprazole and 4.6% with cimetidine had significant upper GI bleeding (bright red blood in the gastric tube not clearing after lavage or persistent Gastroccult-positive "coffee grounds" material). Non-inferiority of esomeprazole to cimetidine was demonstrated. The safety profiles of both drugs were similar and as expected in critically ill patients. Esomeprazole is effective in preventing upper GI bleeding in critically ill Chinese patients, as demonstrated by the non-inferiority analysis using cimetidine as an active control.

To evaluate the efficacy and clinical outcomes of transcatheter arterial embolization (TAE) for gastrointestinal (GI) bleeding from gastrointestinal stromal tumor (GIST). TAE was performed in 20 referred patients (male:female = 13:7; median age, 56.3 y) for GI bleeding from GISTs. The locations of GISTs were assessed using contrast-enhanced computed tomography (CT) and catheter angiography. The technical and clinical success of TAE and clinical outcomes including procedure-related complications, recurrent bleeding, 30-day and overall mortality, and cumulative survival were evaluated. The sites of GIST-related bleeding or tumor staining were the jejunum (n = 9), stomach (n = 5), ileum (n = 3), duodenum (n = 2), and jejunum and colon (n = 1). Angiography showed bleeding from GIST in 5 patients, and tumor staining was noted in only 15 patients. TAE was performed for patients with and without contrast medium extravasation on angiography. Technical and clinical success rates of TAE were 95% (19 of 20 patients) and 90% (18 of 20 patients), respectively. Recurrent bleeding was noted in 1 patient. There were no procedure-related complications. In 15 patients, surgical resection of the tumors was performed after TAE. The 30-day and overall mortality rates were 10% (2 of 20 patients) and 30% (6 of 20 patients), respectively. TAE is a safe and effective method for controlling GI bleeding from the GIST.

Review: pharmacotherapeutic agents in the treatment of portal hypertension.

Certain vasoactive substances reduce portal pressure in patients or animals with portal hypertension by either inducing splanchnic vasoconstriction or reducing hepatic vascular resistance. Studies have shown that propranolol or nadolol significantly reduce the risk of a first episode of gastrointestinal (GI) bleeding and increase the survival rate in patients with cirrhosis and oesophageal varices. Isosorbide-5-mononitrate is also effective in the prevention of bleeding. The combination of beta-blockers and nitrates may be more effective than one drug alone. These results show that beta-adrenoceptor antagonists must be used to prevent the first episode of GI bleeding. Beta-blocker administration also significantly reduces the risk of recurrent GI bleeding and increases the survival rate in patients with cirrhosis. Studies have shown that propranolol is as effective as endoscopic sclerotherapy. The combination of a beta-blocker with endoscopic sclerotherapy may be more effective than pharmacological or endoscopic treatment alone for the prevention of rebleeding. Finally, new experimental and clinical studies are needed to improve the pharmacological treatment of portal hypertension.

ACG Clinical Guideline: Management of Patients With Acute Lower Gastrointestinal Bleeding.

PubMed

Strate, Lisa L; Gralnek, Ian M

2016-04-01

This guideline provides recommendations for the management of patients with acute overt lower gastrointestinal bleeding. Hemodynamic status should be initially assessed with intravascular volume resuscitation started as needed. Risk stratification based on clinical parameters should be performed to help distinguish patients at high- and low-risk of adverse outcomes. Hematochezia associated with hemodynamic instability may be indicative of an upper gastrointestinal (GI) bleeding source and thus warrants an upper endoscopy. In the majority of patients, colonoscopy should be the initial diagnostic procedure and should be performed within 24 h of patient presentation after adequate colon preparation. Endoscopic hemostasis therapy should be provided to patients with high-risk endoscopic stigmata of bleeding including active bleeding, non-bleeding visible vessel, or adherent clot. The endoscopic hemostasis modality used (mechanical, thermal, injection, or combination) is most often guided by the etiology of bleeding, access to the bleeding site, and endoscopist experience with the various hemostasis modalities. Repeat colonoscopy, with endoscopic hemostasis performed if indicated, should be considered for patients with evidence of recurrent bleeding. Radiographic interventions (tagged red blood cell scintigraphy, computed tomographic angiography, and angiography) should be considered in high-risk patients with ongoing bleeding who do not respond adequately to resuscitation and who are unlikely to tolerate bowel preparation and colonoscopy. Strategies to prevent recurrent bleeding should be considered. Nonsteroidal anti-inflammatory drug use should be avoided in patients with a history of acute lower GI bleeding, particularly if secondary to diverticulosis or angioectasia. Patients with established high-risk cardiovascular disease should not stop aspirin therapy (secondary prophylaxis) in the setting of lower GI bleeding. [corrected]. The exact timing depends on the severity of bleeding, perceived adequacy of hemostasis, and the risk of a thromboembolic event. Surgery for the prevention of recurrent lower gastrointestinal bleeding should be individualized, and the source of bleeding should be carefully localized before resection.

Ankaferd hemostat in the management of gastrointestinal hemorrhages

2011-01-01

Gastrointestinal (GI) bleeding refers to any hemorrhage ascribed to the pathologies of the gastrointestinal tract, extending from the mouth to the anal canal. Despite the recent improvements in the endoscopic, hemostatic and adjuvant pharmacologic techniques, the reported mortality is still around 5%-10% for peptic ulcer bleeding and about 15%-20% for variceal hemorrhages. Although endoscopic management reduces the rates of re-bleeding, surgery, and mortality in active bleeding; early recurrence ratios still occur in around 20% of the cases even with effective initial hemostatic measures. In this quest for an alternative pro-hemostatic agent for the management of GI bleedings, Ankaferd blood stopper (ABS) offers a successful candidate, specifically for “difficult-to-manage” situations as evidenced by data presented in several studies. ABS is a standardized mixture of the plants Thymus vulgaris, Glycyrrhiza glabra, Vitis vinifera, Alpinia officinarum, and Urtica dioica. It is effective in both bleeding individuals with normal hemostatic parameters and in patients with deficient primary and/or secondary hemostasis. ABS also modulates the cellular apoptotic responses to hemorrhagic stress, as well as hemostatic hemodynamic activity. Through its effects on the endothelium, blood cells, angiogenesis, cellular proliferation, vascular dynamics, and wound healing, ABS is now becoming an effective alternative hemostatic medicine for gastrointestinal bleedings that are resistant to conventional anti-hemorrhagic measurements. The aim of this review is to outline current literature experience suggesting the place of ABS in the management of GI bleeding, and potential future controlled trials in this complicated field.

Bleeding lesion anywhere in the GI tract can cause positive reaction to Immunological Fecal Occult Blood Test (FOBT). Although any colonic lesion can cause occult lower GI bleeding, relative frequency of this lesion not known. Guaic based tests require prior preparation and dietary restriction and less sensitive and specific than IFOBT for detection of occult bleeding .IFOBT is specific for human hemoglobin and is more sensitive and specific for detection of occult bleeding from any colonic lesion. Aim of this study was to diagnose occult gastrointestinal bleeding with positive IFOBT and the prevalence of colorectal disease in IFOBT positive patients in a tertiary care hospital in Bangladesh. This was a prospective cross sectional study conducted in Department of gastroenterology in collaboration with clinical pathology, BSMMU, Dhaka during the period of January 2009 to December 2009. In this study 200 patients meeting the inclusion criteria were included. Detailed clinical history and physical findings were recorded; FOBT was done on single stool specimen. Positive occult bleeding was confirmed in 90 patients of whom 80 patients underwent colonoscopy. The mean age of study population was 36.73±13.64 (range 16 to 72) years. At colonoscopy lesion were identified in 46(57.50%) patients, of which colonic polyp in12 (15%), colorectal cancer in 11(13.7%), inflammatory bowel disease in 3(3.75%), hemorrhoids and anal fissure in 7(8.75%), tuberculosis in 5(6.25%), and proctitis in 1(1.25%) cases. A positive IFOBT is more sensitive and specific test than other FOBT for detection of occult lower GI bleeding of colonic origin. In this study colorectal diseases were detected in 57.50% of the IFOBT positive patients, so IOBT can be used as an important diagnostic tool for detection of occult lower GI bleeding.

From April 2007 to February 2013, 29 patients with upper gastrointestinal bleeding underwent endovascular diagnostics and treatment. The diagnosis was established by endoscopy, computed tomography or clinically based on a significant decrease in hemoglobin. Transcatheter arterial embolisation was performed with coils, liquid embolic agents, and particles. The technical and clinical outcomes were assessed by postinterventional endoscopy, hemoglobin concentrations, number of necessary transfusions, or surgical interventions, as well as by post-interventional mortality within 28 days after the procedure. Selective angiographic embolisation in upper gastrointestinal bleeding was primarily successful technically and clinically in 22 of 29 patients. In 4/29 cases an angiographic reintervention was performed, which was successful in 3 cases. In 3 cases of primarily technically unsuccessful procedures reintervention was not attempted. No catheterisation-related complications were recorded. Peri-interventional mortality was 31%, but only 2 of these patients died due to uncontrolled massive bleeding, whereas the lethal outcome in the other 7 patients was due to their underlying diseases. Transcatheter arterial embolisation is an effective and rapid method in the management of upper gastrointestinal bleeding. Radiological endovascular interventions may considerably contribute to reduced mortality in GI bleeding by avoiding a potential surgical procedure following unsuccessful endoscopic treatment. The study underlines the importance of the combination of interventional endoscopy with interventional radiology in secondary care hospitals for patient outcome in complex and complicated upper gastrointestinal bleeding situations. © Georg Thieme Verlag KG Stuttgart · New York.

Transcatheter arterial embolization (TAE) is a therapeutic option for endoscopically unmanageable upper gastrointestinal (GI) bleeding. We aimed to assess the efficacy and clinical outcomes of TAE for acute non-variceal upper GI bleeding and to identify predictors of recurrent bleeding within 30 days. Visceral angiography was performed in 66 patients (42 men, 24 women; mean age, 60.3 ± 12.7 years) who experienced acute non-variceal upper GI bleeding that failed to be controlled by endoscopy during a 7-year period. Clinical information was reviewed retrospectively. Outcomes included technical success rates, complications, and 30-day rebleeding and mortality rates. TAE was feasible in 59 patients. The technical success rate was 98%. Rebleeding within 30 days was observed in 47% after an initial TAE and was managed with re-embolization in 8, by endoscopic intervention in 5, by surgery in 2, and by conservative care in 12 patients. The 30-day overall mortality rate was 42.4%. In the case of initial endoscopic hemostasis failure (n = 34), 31 patients underwent angiographic embolization, which was successful in 30 patients (96.8%). Rebleeding occurred in 15 patients (50%), mainly because of malignancy. Two factors were independent predictors of rebleeding within 30 days by multivariate analysis: coagulopathy (odds ratio [OR] = 4.37; 95% confidence interval [CI]: 1.25-15.29; p = 0.021) and embolization in ≥2 territories (OR = 4.93; 95% CI: 1.43-17.04; p = 0.012). Catheterization-related complications included hepatic artery dissection and splenic embolization. TAE controlled acute non-variceal upper GI bleeding effectively. TAE may be considered when endoscopic therapy is unavailable or unsuccessful. Correction of coagulopathy before TAE is recommended.

Acute upper gastrointestinal bleeding (UGIB) is the most common reason that the 'on-call' gastroenterologist is consulted. Despite the diagnostic and therapeutic capabilities of upper endoscopy, there is still significant associated morbidity and mortality in patients experiencing acute UGIB, thus this is a true GI emergency. Acute UGIB is divided into non-variceal and variceal causes. The most common type of acute UGIB is 'non-variceal' and includes diagnoses such as peptic ulcer (gastric and duodenal), gastroduodenal erosions, Mallory-Weiss tears, erosive oesophagitis, arterio-venous malformations, Dieulafoy's lesion, and upper GI tract tumours and malignancies. This article focuses exclusively on initial management strategies for acute upper GI bleeding. We discuss up to date and evidence-based strategies for patient risk stratification, initial patient management prior to endoscopy, potential causes of UGIB, role of proton pump inhibitors, prokinetic agents, prophylactic antibiotics, vasoactive pharmacotherapies, and timing of endoscopy.

Objective To determine whether a potential pharmacokinetic interaction between warfarin and orally administered anti-infectives increases the risk of hospitalization for gastrointestinal (GI) bleeding in warfarin users. Methods We conducted a nested case-control and case-crossover study in US Medicaid data. Logistic regression was used to determine the association between GI bleeding and prior use of ciprofloxacin, levofloxacin, gatifloxacin, cotrimoxazole, or fluconazole, all versus no exposure and versus cephalexin, which would not be expected to interact with warfarin. Results All anti-infectives examined exhibited an elevated odds ratio (OR) vs. no exposure. Using cephalexin as the reference category, ORs for cotrimoxazole (OR:1.68 [95% CI:1.21–2.33] in the prior 6–10 days) and fluconazole (OR:2.09 [95% CI:1.34–3.26] in the prior 11–15 days) were significantly elevated. Conclusions Warfarin users who had received an anti-infective agent showed a substantially increased risk of GI bleeding. Nonetheless, a drug-drug interaction with warfarin was evident only for cotrimoxazole and fluconazole. PMID:18685566

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.

To evaluate outcomes of transcatheter arterial embolization (TAE) for gastric cancer-related gastrointestinal (GI) bleeding and factors associated with successful TAE and improved survival after TAE. This retrospective study included 43 patients (34 men; age 60.6 y ± 13.6) with gastric cancer-related GI bleeding undergoing angiography between January 2000 and December 2015. Clinical course, laboratory findings, and TAE characteristics were reviewed. Technical success of TAE was defined as target area devascularization, and clinical success was defined as bleeding cessation with hemodynamic stability during 72 hours after TAE. Student t test was used for comparison of continuous variables, and Fisher exact test was used for categorical variables. Univariate and multivariate analysis were performed to identify predictors of successful TAE and 30-day survival after TAE. TAE was performed in 40 patients. Technical and clinical success rates of TAE were 85.0% and 65.0%, respectively. Splenic infarction occurred in 2 patients as a minor complication. Rebleeding after TAE occurred in 7 patients. Death related to bleeding occurred in 5 patients. Active bleeding (P = .044) and higher transfusion requirement (3.3 U ± 2.6 vs 1.8 U ± 1.7; P = .039) were associated with TAE failure. Successful TAE predicted improved 30-day survival after TAE on univariate and multivariate analysis (P = .018 and P = .022; odds ratio, 0.132). TAE for gastric cancer-associated GI bleeding may be a lifesaving procedure. Severe bleeding with a higher transfusion requirement and active bleeding on angiography predicted TAE failure.

Delayed treatment of the massive bleeding in gynecologic and obstetric conditions can cause high morbidity and mortality. The aim of this study is to assess the angiographic findings and outcomes of transarterial embolization in cases of massive hemorrhage from underlying gynecological and obstetrical conditions. This is a retrospective study of 18 consecutive patients who underwent transarterial embolization of uterine and/or hypogastric arteries due to massive bleeding from gynecological and obstetrical causes from January 2006 to December 2011. The underlying causes of bleeding, angiographic findings, technical success rates, clinical success rates, and complications were evaluated. Massive gynecological and obstetrical bleeding occurred in 12 cases and 6 cases, respectively. Gestational trophoblastic disease was the most common cause of gynecological bleeding. The most common cause of obstetrical hemorrhage was primary post-partum hemorrhage. Tumor stain was the most frequent angiographic finding (11 cases) in the gynecological bleeding group. The most common angiographic findings in obstetrical patients were extravasation (2 cases) and pseudoaneurysm (2 cases). Technical and final clinical success rates were found in all 18 cases and 16 cases. Collateral arterial supply, severe metritis, and unidentified cervical laceration were causes of uncontrolled bleeding. Only minor complications occurred, which included pelvic pain and groin hematoma. Percutaneous transarterial embolization is a highly effective and safe treatment to control massive bleeding in gynecologic and obstetric emergencies.

Bleeding due to ectopic varices in a urinary diversion: A multidisciplinary diagnostic and therapeutic challenge

PubMed Central

Acosta, Eduardo Mariano Albers; Reyes, Alfonsi Friera; Menéndez, Ricardo Brime

2015-01-01

The ectopic varices in patients with portal hypertension are those that occur at any level of the gastrointestinal (GI) tract, regardless of the varices that occur at the esophageal level. These ectopic varices account for 2–5% of the causes of GI bleeding varices. The risk of bleeding is quadrupled compared to the esophagogastric area, with a mortality of up to 40%. The transjugular intrahepatic portosystemic shunt, should be considered in cases secondary to recurrent bleeding varices. We present a case report of an urological emergency of bleeding in a urinary diversion secondary to ectopic varices successfully treated through the placement of transjugular intrahepatic portosystemic shunt. The condition described here is rare, but important, as it can be a life-threatening complication of portal hypertension. This kind of complication should be known by urologic surgeons managing patients with urinary diversions. PMID:26834901

Pelvic radiation disease: Updates on treatment options

Pelvic cancers are among the most frequently diagnosed neoplasms and radiotherapy represents one of the main treatment options. The irradiation field usually encompasses healthy intestinal tissue, especially of distal large bowel, thus inducing gastrointestinal (GI) radiation-induced toxicity. Indeed, up to half of radiation-treated patients say that their quality of life is affected by GI symptoms (e.g., rectal bleeding, diarrhoea). The constellation of GI symptoms - from transient to long-term, from mild to very severe - experienced by patients who underwent radiation treatment for a pelvic tumor have been comprised in the definition of pelvic radiation disease (PRD). A correct and evidence-based therapeutic approach of patients experiencing GI radiation-induced toxicity is mandatory. Therapeutic non-surgical strategies for PRD can be summarized in two broad categories, i.e., medical and endoscopic. Of note, most of the studies have investigated the management of radiation-induced rectal bleeding. Patients with clinically significant bleeding (i.e., causing chronic anemia) should firstly be considered for medical management (i.e., sucralfate enemas, metronidazole and hyperbaric oxygen); in case of failure, endoscopic treatment should be implemented. This latter should be considered the first choice in case of acute, transfusion requiring, bleeding. More well-performed, high quality studies should be performed, especially the role of medical treatments should be better investigated as well as the comparative studies between endoscopic and hyperbaric oxygen treatments.

Portal hypertension secondary to portal vein obstruction following liver transplant occurs in 5%-10% of children. Jejunal varices are uncommon in this group. We present a case series of children with significant GI blood loss, negative upper endoscopy, and jejunal varices detected by CE. Case series of patients who had CE for chronic GI blood loss following liver transplantation. Three patients who had their initial transplants at a median age of 7 months were identified at our institution presenting at a median age of 8 years (range 7-16 years) with a median Hgb of 2.8 g/dL (range 1.8-6.8 g/dL). Upper endoscopy was negative for significant esophageal varices, gastric varices, and bleeding portal gastropathy in all three children. All three patients had significant jejunal varices noted on CE in mid-jejunum. Jejunal varices were described as large prominent bluish vessels underneath visualized mucosa, one with evidence of recent bleeding. The results led to venoplasty of the portal vein in two patients and a decompressive shunt in one patient with resolution of GI bleed and anemia. CE is useful to diagnose intestinal varices in children with portal hypertension and GI bleeding following liver transplant. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

To investigate the early upper gastrointestinal endoscopy (endoscopy) significantly reduces mortality resulting from upper gastrointestinal (GI) bleeding. Upper GI bleeding was defined as 1a, 1b, 2a, and 2b according to the Forrest classification. The hemoglobin (Hb), and C-reactive protein (CRP) were examined at around the day of endoscopy and 3 mo prior to endoscopy. The rate of change was calculated as follows: (the result of blood examination on the day of endoscopy - the results of blood examination 3 mo prior to endoscopy)/(results of blood examination 3 mo prior to endoscopy). Receiver operating characteristic curves were created to determine threshold values. Seventy-nine men and 77 women were enrolled. There were 17 patients with upper GI bleeding: 12 with a gastric ulcer, 3 with a duodenal ulcer, 1 with an acute gastric mucosal lesion, and 1 with gastric cancer. The area under the curve (AUC), threshold, sensitivity, and specificity of Hb around the day of endoscopy were 0.902, 11.7 g/dL, 94.1%, and 77.1%, respectively, while those of CRP were 0.722, 0.5 mg/dL, 70.5%, and 73%, respectively. The AUC, threshold, sensitivity, and specificity of the rate of change of Hb were 0.851, -21.3%, 76.4%, and 82.6%, respectively, while those of CRP were 0.901, 100%, 100%, and 82.5%, respectively. Predictors for upper GI bleeding were Hb < 11.7 g/dL, reduction rate in the Hb > 21.3% and an increase in the CRP > 100%, 3 mo before endoscopy.

Distinctive aspects of peptic ulcer disease, Dieulafoy's lesion, and Mallory-Weiss syndrome in patients with advanced alcoholic liver disease or cirrhosis

PubMed Central

Nojkov, Borko; Cappell, Mitchell S

2016-01-01

AIM: To systematically review the data on distinctive aspects of peptic ulcer disease (PUD), Dieulafoy’s lesion (DL), and Mallory-Weiss syndrome (MWS) in patients with advanced alcoholic liver disease (aALD), including alcoholic hepatitis or alcoholic cirrhosis. METHODS: Computerized literature search performed via PubMed using the following medical subject heading terms and keywords: “alcoholic liver disease”, “alcoholic hepatitis”,“ alcoholic cirrhosis”, “cirrhosis”, “liver disease”, “upper gastrointestinal bleeding”, “non-variceal upper gastrointestinal bleeding”, “PUD”, ‘‘DL’’, ‘‘Mallory-Weiss tear”, and “MWS’’. RESULTS: While the majority of acute gastrointestinal (GI) bleeding with aALD is related to portal hypertension, about 30%-40% of acute GI bleeding in patients with aALD is unrelated to portal hypertension. Such bleeding constitutes an important complication of aALD because of its frequency, severity, and associated mortality. Patients with cirrhosis have a markedly increased risk of PUD, which further increases with the progression of cirrhosis. Patients with cirrhosis or aALD and peptic ulcer bleeding (PUB) have worse clinical outcomes than other patients with PUB, including uncontrolled bleeding, rebleeding, and mortality. Alcohol consumption, nonsteroidal anti-inflammatory drug use, and portal hypertension may have a pathogenic role in the development of PUD in patients with aALD. Limited data suggest that Helicobacter pylori does not play a significant role in the pathogenesis of PUD in most cirrhotic patients. The frequency of bleeding from DL appears to be increased in patients with aALD. DL may be associated with an especially high mortality in these patients. MWS is strongly associated with heavy alcohol consumption from binge drinking or chronic alcoholism, and is associated with aALD. Patients with aALD have more severe MWS bleeding and are more likely to rebleed when compared to non-cirrhotics. Pre-endoscopic management of acute GI bleeding in patients with aALD unrelated to portal hypertension is similar to the management of aALD patients with GI bleeding from portal hypertension, because clinical distinction before endoscopy is difficult. Most patients require intensive care unit admission and attention to avoid over-transfusion, to correct electrolyte abnormalities and coagulopathies, and to administer antibiotic prophylaxis. Alcoholics should receive thiamine and be closely monitored for symptoms of alcohol withdrawal. Prompt endoscopy, after initial resuscitation, is essential to diagnose and appropriately treat these patients. Generally, the same endoscopic hemostatic techniques are used in patients bleeding from PUD, DL, or MWS in patients with aALD as in the general population. CONCLUSION: Nonvariceal upper GI bleeding in patients with aALD has clinically important differences from that in the general population without aALD, including: more frequent and more severe bleeding from PUD, DL, or MWS.

Pantoprazole for the treatment of peptic ulcer bleeding and prevention of rebleeding.

PubMed

van Rensburg, Christo J; Cheer, Susan

2012-01-01

Adding proton pump inhibitors (PPIs) to endoscopic therapy has become the mainstay of treatment for peptic ulcer bleeding, with current consensus guidelines recommending high-dose intravenous (IV) PPI therapy (IV bolus followed by continuous therapy). However, whether or not high-dose PPI therapy is more effective than low-dose PPI therapy is still debated. Furthermore, maintaining pH ≥ 4 appears to prevent mucosal bleeding in patients with acute stress ulcers; thus, stress ulcer prophylaxis with acid-suppressing therapy has been increasingly recommended in intensive care units (ICUs). This review evaluates the evidence for the efficacy of IV pantoprazole, a PPI, in preventing ulcer rebleeding after endoscopic hemostasis, and in controlling gastric pH and protecting against upper gastrointestinal (GI) bleeding in high-risk ICU patients. The review concludes that IV pantoprazole provides an effective option in the treatment of upper GI bleeding, the prevention of rebleeding, and for the prophylaxis of acute bleeding stress ulcers.

Nonvariceal upper gastrointestinal bleeding: differences in outcome for patients admitted to internal medicine and gastroenterological services.

It has been suggested that admission to a gastroenterology service (GAS) is associated with a better prognosis and lower cost for treatment of gastrointestinal (GI) diseases, such as upper GI bleeding (UGB). However, a large potential bias by higher comorbidity on internal medicine services (MED) could not be excluded from these studies. We therefore compared patients with upper GI bleeding admitted to a gastroenterology or internal medicine department, with special emphasis on prognostic factors, such as comorbidity, and outcome. Between 1991 and 1995, 322 patients were admitted to our hospital for UGB. Forty-five patients had variceal and 277 patients had nonvariceal upper GI bleeding (NUGB). Of 232 patients with primary NUGB, 125 were admitted to GAS and 93 to MED. The charts of these patients were revised, comorbidity was carefully recorded, and the Rockall risk score was calculated. All deaths were individually classified as unavoidable, mostly due to severe underlying illness, or potentially avoidable. No differences in delay for endoscopy or treatment were observed between GAS and MED. The rebleeding, surgery, and mortality rates in GAS and MED patients were 11.6% versus 11.5% (NS), 7.8% versus 7.3% (NS), and 2.4% versus 10.8% (p = 0.02), respectively. Rockall scores differed between GAS and MED patients (3.1 +/- 1.8 vs 3.7 +/- 1.7, p = 0.02). The mortality rate stratified by Rockall score was lower for the GAS patients. However, individual analysis revealed that only three of 13 deaths were potentially avoidable: two of 10 at the MED and one of three at the GAS. The lower mortality among nonvariceal upper GI bleeding patients admitted to a gastroenterological service compared to an internal medicine service was mainly due to lesser comorbidity. This effect was not detected by stratification according to Rockall, but shown with analysis of individual patient charts only. The latter underscores the potential pitfalls when comparing outcome or cost of treatment between different medical services.

Vascular malformations of the gastrointestinal tract are rare phenomenon. They are generally manifested by upper or lower GI - bleeding and do not resolve spontaneously. Emergency intervention is necessary. This paper reports on 10 cases, treated in the Dept. of Pediatric surgery of the FU Berlin, recorded from 1981 to 1999. We use the Nd:YAG laser 1064 nm, Fibertom 5100, Dornier, Germany, with a 600nm barefiber. Reduction in size of the hemangiomas and stop of the GI-bleeding was achieved in all cases.

Endoscopic management and outcomes of pregnant women hospitalized for nonvariceal upper GI bleeding: a nationwide analysis.

Upper GI endoscopy has an important diagnostic and therapeutic role in the management of nonvariceal upper GI bleeding (NVUGB). To characterize nationwide patterns of utilization of upper GI endoscopy in pregnant women with NVUGB and to assess health outcomes. Retrospective cohort study. Participating hospitals from the Nationwide Inpatient Sample, 1998-2007. Pregnant and age-matched nonpregnant women admitted for NVUGB. The study population was classified as pregnant women with NVUGB (n = 1210) and nonpregnant women with NVUGB (n = 6050). Rate of upper GI endoscopy, maternal mortality, fetal death/complications, and premature delivery. Pregnant women were less likely than nonpregnant women to undergo upper GI endoscopy (26% vs 69%; P < .0001) even after adjustment for comorbidities, transfusion requirement, and the presence of hypovolemic shock (adjusted odds ratio, 0.19; 95% confidence interval, 0.16-0.22). Among those who underwent endoscopy, pregnant women were less likely to undergo the procedure within 24 hours of admission (50% vs 57%; P = .02). Mortality was lower among pregnant women compared with nonpregnant women (0% vs 0.6%; P = .006). In comparing outcomes between those who did and did not undergo endoscopy, there was no difference in fetal loss (0.2% vs 0.6%), fetal distress/complications (2.7% vs 2.6%), or premature delivery (7.3% vs 6.4%). The study was based on administrative data. A conservative nonendoscopic approach is common in the management of pregnant women with NVUGB and is not associated with worse maternal or fetal outcomes. Upper GI endoscopy is, however, safe when judiciously implemented in the actively bleeding patient. Copyright © 2010 American Society for Gastrointestinal Endoscopy. Published by Mosby, Inc.

McFarlane, Michael; Eaden, Jayne; Burch, Nicola; Disney, Ben

2017-10-01

Acute upper gastrointestinal (GI) bleeding is a common condition in the UK with 50-70,000 admissions per year. In 20% of cases no cause can be found on endoscopy. Here, we present the case of a young female patient who was admitted on three occasions with large volume haematemesis and bleeding from other sites. She was extensively investigated and underwent multiple endoscopic procedures. She was eventually diagnosed with factitious disorder after concerns were raised about the inconsistent nature of her presentations. She was found to be venesecting herself from her intravenous cannula, and ingesting the blood to simulate upper GI bleeding. This is a rare cause of 'haematemesis' but perhaps not as rare as is thought.

Eighty five children were evaluated endoscopically for recurrent lower gastrointestinal (GI) bleeding. The male: female ratio was 2.4:1 with a mean age of 6 years (range 8 months to 2 years). After adequate bowel preparation endoscopic evaluation was done using olympus CF 101 colonoscope. Sedation was given only in two patients. Full length colonoscopy had been done in 16 cases only, to look for extent of disease in 8 cases and to ascertain site of bleeding when no lesion could be seen on sigmoidoscopy. Juvenile polyps were seen in 40 cases, amoebic ulcer in 20, solitary rectal ulcer in 4 and polyposis syndrome in 5 cases. Sigmoidoscopy alone could establish the diagnose in 76 cases. We conclude that flexible sigmoidoscopy alone is safe and adequate in ascertaining the cause of prolonged recurrent lower GI bleeding.

We aimed to identify factors associated with massive post-partum bleeding in pregnancies with placenta previa and to establish a scoring model to predict post-partum severe bleeding. A retrospective cohort study was performed in 506 healthy singleton pregnancies with placenta previa from 2006 to 2016. Cases with intraoperative blood loss (≥2000 mL), packed red blood cells transfusion (≥4), uterine artery embolization, or hysterectomy were defined as massive bleeding. After performing multivariable analysis, using the adjusted odds ratios (aOR), we formulated a scoring model. Seventy-three women experienced massive post-partum bleeding (14.4%). After multivariable analysis, seven variables were associated with massive bleeding: maternal old age (≥35 years; aOR 1.79, 95% confidence interval [CI] 1.00-3.20, P = 0.049), antepartum bleeding (aOR 4.76, 95%CI 2.01-11.02, P < 0.001), non-cephalic presentation (aOR 3.41, 95%CI 1.40-8.30, P = 0.007), complete placenta previa (aOR 1.93, 95%CI 1.05-3.54, P = 0.034), anterior placenta (aOR 2.74, 95%CI 1.54-4.89, P = 0.001), multiple lacunae (≥4; aOR 2.77, 95%CI 1.54-4.99, P = 0.001), and uteroplacental hypervascularity (aOR 4.51, 95%CI 2.30-8.83, P < 0.001). We formulated a scoring model including maternal old age (<35: 0, ≥35: 1), antepartum bleeding (no: 0, yes: 2), fetal non-cephalic presentation (no: 0, yes: 2), placenta previa type (incomplete: 0, complete: 1), placenta location (posterior: 0, anterior: 1), uteroplacental hypervascularity (no: 0, yes: 2), and multiple lacunae (no: 0, yes: 1) to predict post-partum massive bleeding. According to our scoring model, a score of 5/10 had a sensitivity of 81% and a specificity of 77% for predicting massive post-partum bleeding. The area under the receiver-operator curve was 0.856 (P < 0.001). The negative predictive value was 95.9%. Our scoring model might provide useful information for prediction of massive post-partum bleeding in pregnancies with placenta previa. © 2017 Japan Society of Obstetrics and Gynecology.

Signet ring adenocarcinoma of the breast with synchronous metastasis to the gastrointestinal (GI) tract is a rare occurrence, typically presenting with abdominal pain, dyspepsia, or GI bleed. We report a case of metastatic breast cancer presenting with a complaint of anemia. A further diagnostic evaluation revealed generalized lymphadenopathy, nodular thickening of the urinary bladder wall, bone lesions, and enlarged pancreas. Biopsies from the lymph nodes, pancreatic biopsy, and bladder nodule all revealed a signet cell carcinoma. An upper and lower GI endoscopy revealed multiple ulcerated gastric mucosal nodules and polypoid folds in the cecum and proximal ascending colon; the biopsies from these lesions were also positive for signet ring cell adenocarcinoma.

The presacral venous system is located under the pelvic fascia covering the anterior of the sacrum and consists of two lateral sacral veins, middle sacral vein, and the veins that communicate them. The presacral venous system can be easily damaged and causes serious bleeding which is difficult to control and may cause intraoperative mortality. Its incidence varies between 3% and 9.4%. Although several methods have been tried to control presacral bleeding, the definitive method of treatment has not yet been identified. We present here our alternative technique in control of massive presacral massive bleeding developed from the presacral plexus secondary to the traction of the specimen during the dissection. The bleeding could not be controlled despite the use of all technical possibilities such as packing, ligation, and hemostatic agents. Bleeding control was provided by GORE-TEX ® graft. We conclude that fıxatıon of GORE-TEX ® aortic patch should be kept in mind for uncontrolled massive presacral bleeding.

Management protocol for acute gastrointestinal bleeding.

Gastro-intestinal haemorrhage is not uncommon and is manifested as haematemesis, melaena or haematochezia. The first step is to resuscitate the patient if necessary and then proceed to make a diagnosis as well as divide patients into high and low-risk groups after taking a good history and performing a physical examination especially to detect the presence of an enlarged spleen. Then one should proceed with an endoscopy and other investigations chosen carefully for their usefulness. Control of bleeding is then tailored to the diagnosis and is usually with drugs, endoscopy, angio-embolisation and surgery in that order. The mortality rate for upper GI bleeding varies from 10 to 30% depending on the proportion of patients with variceal haemorrhage included. For lower GI bleeding mortality is in the region of 20% and for obscure GI bleeding outpatient mortality is 12%. The main points to remember are that the management of these patients in India should be different from those described in Western textbooks and suited to their specific needs and the facilities available locally. However, in spite of the widespread lack of complex diagnostic techniques and a shortage of blood for transfusion we believe that by adopting an aggressive step-by-step approach tailored to our own environment we will be able to save most of our patients who are usually young and have few comorbid conditions.

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). The ROCKET AF trial demonstrated similar risks of stroke/systemic embolism and major/nonmajor clinically relevant bleeding (principal safety endpoint) with rivaroxaban and warfarin. 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. 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. 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.

Hemorrhoids usually do not pose diagnostic difficulties and they rarely cause massive bleeding. We report a case of massive rectal bleeding over 18 h needing 22 U blood transfusion treated by superselective transcatheter coil embolization 12 h following operative treatment performed in a different hospital. Diagnostic angiography with a view to superselective embolization, following failure of sigmoidoscopy to localize and treat the cause of hemorrhage, might act as a life-saving treatment in massive rectal bleeding, obviating the need for repeated endoscopy or emergency surgery.

Purpose. To assess outcomes after microcoil embolization for active lower gastrointestinal (GI) bleeding. Methods. We retrospectively studied all consecutive patients in whom microcoil embolization was attempted to treat acute lower GI bleeding over 88 months. Baseline, procedural, and outcome parameters were recorded following current Society of Interventional Radiology guidelines. Outcomes included technical success, clinical success (rebleeding within 30 days), delayed rebleeding (>30 days), and major and minor complication rates. Follow-up consisted of clinical, endoscopic, and pathologic data. Results. Nineteen patients (13 men, 6 women; mean age {+-} 95% confidence interval = 70 {+-} 6 years) requiring blood transfusion (10 {+-}more » 3 units) had angiography-proven bleeding distal to the marginal artery. Main comorbidities were malignancy (42%), coagulopathy (28%), and renal failure (26%). Bleeding was located in the small bowel (n = 5), colon (n 13) or rectum (n = 1). Technical success was obtained in 17 patients (89%); 2 patients could not be embolized due to vessel tortuosity and stenoses. Clinical follow-up length was 145 {+-} 75 days. Clinical success was complete in 13 (68%), partial in 3 (16%), and failed in 2 patients (11%). Delayed rebleeding (3 patients, 27%) was always due to a different lesion in another bowel segment (0 late rebleeding in embolized area). Two patients experienced colonic ischemia (11%) and underwent uneventful colectomy. Two minor complications were noted. Conclusion. Microcoil embolization for active lower GI bleeding is safe and effective in most patients, with high technical and clinical success rates, no procedure-related mortality, and a low risk of bowel ischemia and late rebleeding.« less

Patients with inherited factor VII (FVII) deficiency display different clinical phenotypes requiring ad hoc management. This study evaluated treatments for spontaneous and traumatic bleeding using data from the Seven Treatment Evaluation Registry (STER). One-hundred one bleeds were analysed in 75 patients (41 females; FVII coagulant activity <1-20%). Bleeds were grouped as haemarthroses (n=30), muscle/subcutaneous haematomas (n=16), epistaxis (n=12), gum bleeding (n=13), menorrhagia (n=16), central nervous system (CNS; n=9), gastrointestinal (GI; n=2) and other (n=3). Of 93 evaluable episodes, 76 were treated with recombinant, activated FVII (rFVIIa), eight with fresh frozen plasma (FFP), seven with plasma-derived FVII (pdFVII) and two with prothrombin-complex concentrates. One-day replacement therapy resulted in very favourable outcomes in haemarthroses, and was successful in muscle/subcutaneous haematomas, epistaxis and gum bleeding. For menorrhagia, single- or multiple-dose schedules led to favourable outcomes. No thrombosis occurred; two inhibitors were detected in two repeatedly treated patients (one post-rFVIIa, one post-pdFVII). In FVII deficiency, most bleeds were successfully treated with single 'intermediate' doses (median 60 µg/kg) of rFVIIa. For the most severe bleeds (CNS, GI) short- or long-term prophylaxis may be optimal.

New therapies for vascular anomalies of the gastrointestinal tract.

PubMed

Fox, Victor L

Vascular anomalies are a morphologically and biologically diverse group of vascular channel abnormalities that are often congenital but may evolve or change over time in the developing child. Classification is based on a combination of physical and biological properties and clinical behavior that differentiate primarily between tumors and malformations and includes a few provisionally unclassified lesions. Anomalies of the gastrointestinal (GI) tract may present clinically with GI bleeding, abdominal pain, high-output cardiac failure, and malabsorption. This review focuses on new therapies for the treatment of GI bleeding. Important new pharmacological therapies include treatment of hemangioma with non-selective and selective beta-antagonist agents, propranolol and atenolol, and treatment of blue rubber bleb nevus syndrome and cutaneo-visceral angiomatosis with thrombocytopenia (also known as multifocal lymphangioendotheliomatosis with thrombocytopenia) with sirolimus, an inhibitor of the mammalian target of rapamycin. Therapeutic endoscopy may offer an effective alternative to bowel resection for colonic varices and other focal vascular anomalies of the GI tract that fail to respond to pharmacological therapy.

Prothrombin complex concentrates (PCC) are approved for urgent reversal of vitamin K antagonists (VKA). Recently, PCC have been used in the management of massive bleeding-associated coagulopathy. The present work evaluates safety and efficacy of PCC in a case series of both VKA reversal and massive bleeding. Retrospective review of cases treated with CCP (January 2010 to February 2013). Safety endpoints were infusion reactions and incidence of thromboembolic events. Efficacy endpoints were: 1) VKA reversal efficacy and 2) Massive bleeding coagulopathy reversal and 24h mortality. Thirty-one patients were included (22 male), median age 61 years (range 30-86). No infusion reactions were detected, and only 1 thrombotic episode was observed. VKA reversal was effective in 100% of patients (6/6), all of them with complete reversal of INR value. In massive bleeding, 24-hour survival was 64% (16/25). Invasive hemostatic procedures were required in 28% of patients (7/25). CCP use was correlated with bleeding control in 44% of cases (11/25), and also significantly associated with survival (p=0.01). CCP are safe and effective for the novel indication of adjuvant treatment in massive bleeding patients, as well as for traditional urgent reversal of VKA.

A Fibreoptic endoscopic study of upper gastrointestinal bleeding at Bugando Medical Centre in northwestern Tanzania: A retrospective review of 240 cases

2012-01-01

Background Upper gastrointestinal (GI) bleeding is recognized as a common and potentially life-threatening abdominal emergency that needs a prompt assessment and aggressive emergency treatment. A retrospective study was undertaken at Bugando Medical Centre in northwestern Tanzania between March 2010 and September 2011 to describe our own experiences with fibreoptic upper GI endoscopy in the management of patients with upper gastrointestinal bleeding in our setting and compare our results with those from other centers in the world. Findings A total of 240 patients representing 18.7% of all patients (i.e. 1292) who had fibreoptic upper GI endoscopy during the study period were studied. Males outnumbered female by a ratio of 2.1:1. Their median age was 37 years and most of patients (60.0%) were aged 40 years and below. The vast majority of the patients (80.4%) presented with haematemesis alone followed by malaena alone in 9.2% of cases. The use of non-steroidal anti-inflammatory drugs, alcohol and smoking prior to the onset of bleeding was recorded in 7.9%, 51.7% and 38.3% of cases respectively. Previous history of peptic ulcer disease was reported in 22(9.2%) patients. Nine (3.8%) patients were HIV positive. The source of bleeding was accurately identified in 97.7% of patients. Diagnostic accuracy was greater within the first 24 h of the bleeding onset, and in the presence of haematemesis. Oesophageal varices were the most frequent cause of upper GI bleeding (51.3%) followed by peptic ulcers in 25.0% of cases. The majority of patients (60.8%) were treated conservatively. Endoscopic and surgical treatments were performed in 30.8% and 5.8% of cases respectively. 140 (58.3%) patients received blood transfusion. The median length of hospitalization was 8 days and it was significantly longer in patients who underwent surgical treatment and those with higher Rockall scores (P < 0.001). Rebleeding was reported in 3.3% of the patients. The overall mortality rate of 11.7% was significantly higher in patients with variceal bleeding, shock, hepatic decompensation, HIV infection, comorbidities, malignancy, age > 60 years and in patients with higher Rockall scores and those who underwent surgery (P < 0.001). Conclusion Oesophageal varices are the commonest cause of upper gastrointestinal bleeding in our environment and it is associated with high morbidity and mortality. The diagnostic accuracy of fibreoptic endoscopy was related to the time interval between the onset of bleeding and endoscopy. Therefore, it is recommended that early endoscopy should be performed within 24 h of the onset of bleeding. PMID:22537571

Full-mouth extraction can be associated with intraoral bleeding, which usually is controlled with local hemostatic measures. Recombinant activated factor VII (rFVIIa) occasionally is used to stop bleeding in a variety of off-label indications, with the main argument curtailing its use being thrombotic events. The authors describe the use of rFVIIa for bleeding after full-mouth extraction in a patient with undiagnosed B-cell lymphocytic leukemia/small lymphocytic lymphoma. A 72-year-old man underwent full-mouth extraction (18 teeth). The next day, the patient experienced massive oral bleeding. The authors administered tranexamic acid, aminocaproic acid, and a total of 12 units of packed red blood cells in addition to local hemostatic measures without control of bleeding. On postoperative day 10, the authors administered 5,000 micrograms of rFVIIa, and within 2 hours oral the bleeding ceased. The authors performed flow cytometry and diagnosed B-cell lymphocytic leukemia/small lymphocytic lymphoma. Unexplained massive oral bleeding despite adequate local hemostatic measures should prompt further investigations for underlying bleeding or coagulation disorders. The authors describe the successful use of rFVIIa in massive oral bleeding. Further studies are mandatory to study the effectiveness of this drug for this off-label indication.

Upper gastrointestinal bleeding in a patient with depression receiving selective serotonin reuptake inhibitor therapy.

PubMed

Kumar, Deepak; Saaraswat, Tanuj; Sengupta, S N; Mehrotra, Saurabh

2009-02-01

Serotonin plays an important role in the normal clotting phenomenon and is released by platelets. Platelets are dependent on a serotonin transporter for the uptake of serotonin, as they cannot synthesize it themselves. Selective serotonin reuptake inhibitors (SSRIs) block the uptake of serotonin into platelets and can cause problems with clotting leading to bleeding. This case report highlights the occurrence of upper gastrointestinal bleeding in the index case on initiating SSRI therapy for depression and the prompt resolution of the same on its discontinuation on two separate occasions. SSRIs may cause upper gastrointestinal (GI) bleeding. Physicians should be aware of the same and should try to rule out previous episodes of upper GI bleed or the presence of other risk factors which might predispose to it before prescribing SSRIs; they should also warn the patients about this potential side effect. Also, the presence of thalassemia trait in the index patient deserves special attention and needs to be explored to see if it might in any way contribute in potentiating this side effect of SSRIs.

Rivaroxaban is an oral anticoagulant approved in the US for prevention of stroke and systemic embolism in patients with non-valvular atrial fibrillation (NVAF). We determined the effectiveness and associated risks of rivaroxaban versus other oral anticoagulants in a large real-world population. We selected NVAF patients initiating oral anticoagulant use in 2010-2014 enrolled in MarketScan databases. Rivaroxaban users were matched with warfarin and dabigatran users by age, sex, enrolment date, anticoagulant initiation date, and high-dimensional propensity score. Study endpoints, including ischemic stroke, intracranial bleeding (ICB), myocardial infarction (MI), and gastrointestinal (GI) bleeding, were identified from inpatient diagnostic codes. Multivariable Cox models were used to assess associations between type of anticoagulant and outcomes. The analysis included 44,340 rivaroxaban users matched to 89,400 warfarin and 16,957 dabigatran users (38% female, mean age 70) with 12 months of mean follow-up. Anticoagulant-naïve rivaroxaban initiators, but not those switching from warfarin, had lower risk of ischemic stroke [hazard ratio (HR) (95% confidence interval (CI)): 0.75 (0.62, 0.91)] and ICB [HR (95%CI): 0.55, (0.39, 0.78)] than warfarin users. In contrast, anticoagulant-experienced rivaroxaban initiators had higher risk of GI bleeding than warfarin users [HR (95%CI): 1.55 (1.32, 1.83)]. Endpoint rates were similar when comparing anticoagulant-naïve rivaroxaban and dabigatran initiators, with the exception of higher GI bleeding risk in rivaroxaban users [HR (95%CI) 1.28 (1.06, 1.54)]. There were no significant differences in the risk of MI among the comparison groups. In this large real-world sample of NVAF patients, effectiveness and risks of rivaroxaban versus warfarin differed by prior anticoagulant status, while effectiveness of rivaroxaban versus dabigatran differed in GI bleeding risk.

Management of Patients with Acute Lower Gastrointestinal Bleeding

Strate, Lisa L.; Gralnek, Ian M.

2016-01-01

This guideline provides recommendations for the management of patients with acute overt lower gastrointestinal hemorrhage. Hemodynamic status should be initially assessed with intravascular volume resuscitation started as needed. Risk stratification based upon clinical parameters should be performed to help distinguish patients at high and low-risk of adverse outcomes. Hematochezia associated with hemodynamic instability may be indicative of an upper GI bleeding source and thus warrants an upper endoscopy. In the majority of patients, colonoscopy should be the initial diagnostic procedure and should be performed within 24 hours of patient presentation after adequate colon preparation. Endoscopic hemostasis therapy should be provided to patients with high risk endoscopic stigmata of bleeding including active bleeding, non-bleeding visible vessel, or adherent clot. The endoscopic hemostasis modality used (mechanical, thermal, injection or combination) is most often guided by the etiology of bleeding, access to the bleeding site, and endoscopist experience with the various hemostasis modalities. Repeat colonoscopy, with endoscopic hemostasis performed if indicated, should be considered for patients with evidence of recurrent bleeding. Radiographic interventions (tagged red blood cell scintigraphy, CT angiography, angiography) should be considered in high-risk patients with ongoing bleeding who do not respond adequately to resuscitation, and who are unlikely to tolerate bowel preparation and colonoscopy. Strategies to prevent recurrent bleeding should be considered. NSAID use should be avoided in patients with a history of acute lower GI bleeding particularly if secondary to diverticulosis or angioectasia. In patients with established cardiovascular disease who require aspirin (secondary prophylaxis), aspirin should not be discontinued. The exact timing depends on the severity of bleeding, perceived adequacy of hemostasis and the risk of a thromboembolic event. Surgery for the prevention of recurrent lower gastrointestinal bleeding should be individualized and the source of bleeding should be carefully localized prior to resection. PMID:26925883

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.

To report short-term results of empiric transcatheter embolization for patients with advanced malignancy and gastrointestinal (GI) hemorrhage directly from a tumor invading the GI tract wall. Between 2005 and 2011, 37 mesenteric angiograms were obtained in 26 patients with advanced malignancy (20 men, six women; mean age, 56.2 y) with endoscopically confirmed symptomatic GI hemorrhage from a tumor invading the GI tract wall. Angiographic findings and clinical outcomes were retrospectively evaluated. Clinical success was defined as absence of signs and symptoms of hemorrhage for at least 30 day following embolization. Active extravasation was demonstrated in three cases. Angiographic abnormalities related to a GI tract tumor were identified on 35 of 37 angiograms, including tumor neovascularity (n = 21), tumor enhancement (n = 24), and luminal irregularity (n = 5). In the absence of active extravasation, empiric embolization with particles and/or coils was performed in 25 procedures. Cessation of hemorrhage (ie, clinical success) occurred more frequently when empiric embolization was performed (17 of 25 procedures; 68%) than when embolization was not performed (two of nine; 22%; P = .03). Empiric embolization resulted in clinical success in 10 of 11 patients with acute GI bleeding (91%), compared with seven of 14 patients (50%) with chronic GI bleeding (P = .04). No ischemic complications were encountered. In patients with advanced malignancy, in the absence of active extravasation, empiric transcatheter arterial embolization for treatment of GI hemorrhage from a direct tumor source demonstrated a 68% short-term success rate, without any ischemic complications.

To evaluate the efficacy and safety of empiric transcatheter arterial embolization (TAE) for patients with massive bleeding from duodenal ulcers. During January 2000 and December 2009, 59 patients with duodenal ulcer bleeding in whom TAE was attempted after endoscopic therapy failed were retrospectively analyzed. The patients were divided into empiric TAE (n = 36) and identifiable TAE (n = 23) groups according to angiographic findings with or without identification of the bleeding sites. The technical and clinical success rate, recurrent bleeding rate, procedure-related complications, and clinical outcomes were evaluated. The technical and clinical success rates of TAE were 100% and 83%. The recurrent bleeding rate, clinical success, duodenal stenosis, and 30-day mortality after TAE were not significantly different between the empiric and identifiable TAE groups. A high rate of technical and clinical success was obtained with empiric TAE comparable to identifiable TAE in patients with massive bleeding from duodenal ulcers. There were no severe complications. Empiric TAE is an effective and safe method when a bleeding site cannot determined by angiography. Copyright © 2011 SIR. Published by Elsevier Inc. All rights reserved.

Extensive traumatic haemothorax is a life-threatening condition that requires the surgeon's resolute approach. Massive bleeding may first lead to hypovoleamic shock, then to haemorrhagic shock. The most common sources are bleeding from the chest wall (intercostal artery), bleeding when the lung parenchyma or major intrathoracic vessels are injured. The case report describes a rare case of massive right-sided haemothorax in pericardial rupture with cardiac herniation in a patient with polytrauma when the source of bleeding was artery pericardium. The report draws attention to the treacherousness of the diagnosis in a polytraumatised patient; the report retrospectively evaluates the interpretation of imaging examinations that were carried out

Red blood cell (RBC) transfusion may be justified in iron deficiency anaemia (IDA) when an increase in oxygen delivery is needed, as sometimes occurs in subjects with haemoglobin <8·0 mg/dL, serious comorbidities or at risk of cardiovascular instability. Earlier investigations showed that some patients with severe IDA requiring transfusion had lower than expected post-transfusion haemoglobin levels with poorer clinical outcomes than other patients. After hypothesizing that haemoglobin responses to transfusion were different and that the underlying gastrointestinal (GI) disorders causing IDA could be a confounder explaining this association, these responses were analysed in a prospective cohort of IDA adults referred for outpatient GI investigation. Transfused patients with proven IDA, baseline haemoglobin at referral <9·0 g/dL and no extraintestinal bleeding were eligible. To assess a homogeneous population, only GI disorders known to cause occult bleeding were considered. Haemoglobin increments per 100 mL of RBCs were investigated. In total, 2818 patients were enrolled over 10·5 years. On multivariable regression, diffuse angiodysplasias and GI cancer independently predicted for reduced increments in post-transfusion haemoglobin [adjusted regression coefficients: -0·082 (95% confidence interval, -0·093 to -0·072) and -0·073 (95% confidence interval, -0·081 to -0·066), respectively, P < 0·001 in both]. Haemoglobin responses in the remaining bleeding disorders were adequate and agreed with the principle that one RBC unit increases the haemoglobin an average of 1 g/dL. The potential differential impact of GI disorders on changes in haemoglobin levels after RBC transfusion could be useful for transfusing physicians, especially for diagnostic purposes. © 2017 International Society of Blood Transfusion.

We report here a case of massive nasal bleeding from the sphenopalatine artery three weeks after endonasal transsphenoidal surgery. This 66-year-old male suffered from massive nasal bleeding with the status of hypovolemic shock. Under general anesthesia, an emergent angiography revealed an extravasation from the sphenopalatine artery. Trans-arterial embolization using coil and n-butyl-cyanoacrylate (NBCA) was performed following the diagnostic angiography. Complete occlusion of the injured artery was achieved. The patient showed good recovery from general anesthesia. Delayed nasal bleeding after endonasal transsphenoidal surgery is a rare but important complication. The sphenopalatine artery and its branch are located in the hidden inferior lateral corner of the sphenoid sinus and may be injured during enlargement of the sphenoid opening. When massive delayed nasal bleeding follows transsphenoidal surgery and damage of the internal carotid artery has been ruled out, endovascular treatment of the external carotid artery should be considered.

Arterioenteric fistula is a rare but serious complication of enteric drained pancreas transplant, which may lead to massive gastrointestinal bleeding. We present 3 patients with failed enteric drained pancreas transplants and massive gastrointestinal bleeding secondary to arterioenteric fistula. One patient was treated by embolization and the 2 others by stent graft placement. Bleeding was successfully controlled in all cases, at follow up of 5 days, 8 months, and 12 months, respectively. One patient died 24 days after embolization, of unknown causes.

The balance between potential aspirin-related risks and benefits is critical in primary prevention. To evaluate the risk for serious bleeding with regular aspirin use in cardiovascular disease (CVD) primary prevention. PubMed, MEDLINE, Cochrane Central Register of Controlled Trials (2010 through 6 January 2015), and relevant references from other reviews. Randomized, controlled trials; cohort studies; and meta-analyses comparing aspirin with placebo or no treatment to prevent CVD or cancer in adults. One investigator abstracted data, another checked for accuracy, and 2 assessed study quality. In CVD primary prevention studies, very-low-dose aspirin use (≤100 mg daily or every other day) increased major gastrointestinal (GI) bleeding risk by 58% (odds ratio [OR], 1.58 [95% CI, 1.29 to 1.95]) and hemorrhagic stroke risk by 27% (OR, 1.27 [CI, 0.96 to 1.68]). Projected excess bleeding events with aspirin depend on baseline assumptions. Estimated excess major bleeding events were 1.39 (CI, 0.70 to 2.28) for GI bleeding and 0.32 (CI, -0.05 to 0.82) for hemorrhagic stroke per 1000 person-years of aspirin exposure using baseline bleeding rates from a community-based observational sample. Such events could be greater among older persons, men, and those with CVD risk factors that also increase bleeding risk. Power to detect effects on hemorrhagic stroke was limited. Harms other than serious bleeding were not examined. Consideration of the safety of primary prevention with aspirin requires an individualized assessment of aspirin's effects on bleeding risks and expected benefits because absolute bleeding risk may vary considerably by patient.

We conducted this study to describe the complications and validate the accuracy of previously reported prognostic indices in predicting the mortality of cirrhotic patients hospitalized for upper GI bleeding. This prospective, observational study included 111 consecutive hospitalizations of 85 cirrhotic patients admitted for GI bleeding. Data obtained included intensive care unit (ICU) admission status, Child-Pugh score, the development of systemic inflammatory response syndrome (SIRS), organ failure, and inhospital mortality. The performances of Garden's, Gatta's, and Acute Physiology and Chronic Health Evaluation (APACHE) II prognostic systems in predicting mortality were assessed. Patients' mean age was 48.7 yr, and the median APACHE II and Child-Pugh scores were 17 and 9, respectively. Their ICU admission rate was 71%. Organ failure developed in 57%, and SIRS in 46% of the patients. Nine patients had acute respiratory distress syndrome, and three patients had hepatorenal syndrome. The inhospital mortality was 21%. The APACHE II, Garden's, and Gatta' s predicted mortality rates were 39%, 24%, and 20%, respectively, and their areas under the receiver operating characteristic curve (AUC) were 0.78, 0.70, and 0.71, respectively. The AUC for Child-Pugh score was 0.76. SIRS and organ failure develop in many patients with hepatic cirrhosis hospitalized for upper GI bleeding, and are associated with increased mortality. Although the APACHE II prognostic system overestimated the mortality of these patients, the receiver operating characteristic curves did not show significant differences between the various prognostic systems.

Upper gastrointestinal issues in athletes.

PubMed

Waterman, Jason J; Kapur, Rahul

2012-01-01

Gastrointestinal (GI) complaints are common among athletes with rates in the range of 30% to 70%. Both the intensity of sport and the type of sporting activity have been shown to be contributing factors in the development of GI symptoms. Three important factors have been postulated as contributing to the pathophysiology of GI complaints in athletes: mechanical forces, altered GI blood flow, and neuroendocrine changes. As a result of those factors, gastroesophageal reflux disease (GERD), nausea, vomiting, gastritis, peptic ulcers, GI bleeding, or exercise-related transient abdominal pain (ETAP) may develop. GERD may be treated with changes in eating habits, lifestyle modifications, and training modifications. Nausea and vomiting may respond to simple training modifications, including no solid food 3 hours prior to an athletic event. Mechanical trauma, decreased splanchnic blood flow during exercise, and non-steroidal anti-inflammatory drugs (NSAID) contribute to gastritis, GI bleeding, and ulcer formation in athletes. Acid suppression with proton-pump inhibitors may be useful in athletes with persistence of any of the above symptoms. ETAP is a common, poorly-understood, self-limited acute abdominal pain which is difficult to treat. ETAP incidence increases in athletes beginning a new exercise program or increasing the intensity of their current exercise program. ETAP may respond to changes in breathing patterns or may resolve simply with continued training. Evaluation of the athlete with upper GI symptoms requires a thorough history, a detailed training log, a focused physical examination aimed at ruling out potentially serious causes of symptoms, and follow-up laboratory testing based on concerning physical examination findings.

Acute bleeding from the upper gastrointestinal system is a medical emergency which is followed by high mortality rate, ranging from 6 to 15% in spite of modern diagnostic methods and treatment. Bleeding from the upper gastrointestinal system may be caused by gastrointestinal stromal tumors of the stomach, which are mainly characterized by occult bleeding, while profuse bleeding rarely occurs accompanied by hemorrhagic shock. Gastrointestinal stromal tumors of stomach are the most common mesenchimal tumors of the gastrointestinal tract. In our study we showed a 60-year-old female patient with profuse bleeding from the stomach and the clinical picture of severe hemorrhagic shock, caused by gastrointestinal stromal tumor. An ovoid junction, raised towards the lumen, covered with ulcerated mucosa in several places and followed by massive arterial bleeding was found intraoperatively, after the performed gastrotomy. Histopathological examination with immunohistochemical analysis confirmed that this was a gastrointestinal stromal tumor of the stomach. Acute bleeding from the digestive system is a sudden and serious condition of the body. Urgent esophagogastroduodenoscopy is a sensitive and specific diagnostic and therapeutic method of choice. Massive bleeding from the upper gastrointestinal tract is very rarely caused by gastrointestinal stromal tumors, whose clinical picture is very heterogeneous and depends on tumor size and location. Abundant bleeding from the tumor is an indication for urgent surgical intervention. According to the literature massive hemorrhage of the upper digestive system can rarely be caused by gastrointestinal stromal tumor of the stomach. It is shown that abundant hemorrhage of the upper digestive tract can be caused with gastric gastrointestinal stromal tumor. Surgical resection is the main form of treatment of gastrointestinal stromal tumors of the digestive system and bleeding from these tumors caused by failure of endoscopic hemostasis.

Gastrointestinal Dose-Histogram Effects in the Context of Dose-Volume–Constrained Prostate Radiation Therapy: Analysis of Data From the RADAR Prostate Radiation Therapy Trial

Purpose: To use a high-quality multicenter trial dataset to determine dose-volume effects for gastrointestinal (GI) toxicity following radiation therapy for prostate carcinoma. Influential dose-volume histogram regions were to be determined as functions of dose, anatomical location, toxicity, and clinical endpoint. Methods and Materials: Planning datasets for 754 participants in the TROG 03.04 RADAR trial were available, with Late Effects of Normal Tissues (LENT) Subjective, Objective, Management, and Analytic (SOMA) toxicity assessment to a median of 72 months. A rank sum method was used to define dose-volume cut-points as near-continuous functions of dose to 3 GI anatomical regions, together with amore » comprehensive assessment of significance. Univariate and multivariate ordinal regression was used to assess the importance of cut-points at each dose. Results: Dose ranges providing significant cut-points tended to be consistent with those showing significant univariate regression odds-ratios (representing the probability of a unitary increase in toxicity grade per percent relative volume). Ranges of significant cut-points for rectal bleeding validated previously published results. Separation of the lower GI anatomy into complete anorectum, rectum, and anal canal showed the impact of mid-low doses to the anal canal on urgency and tenesmus, completeness of evacuation and stool frequency, and mid-high doses to the anorectum on bleeding and stool frequency. Derived multivariate models emphasized the importance of the high-dose region of the anorectum and rectum for rectal bleeding and mid- to low-dose regions for diarrhea and urgency and tenesmus, and low-to-mid doses to the anal canal for stool frequency, diarrhea, evacuation, and bleeding. Conclusions: Results confirm anatomical dependence of specific GI toxicities. They provide an atlas summarizing dose-histogram effects and derived constraints as functions of anatomical region, dose, toxicity, and endpoint for informing future radiation therapy planning.« less

Naproxen-PC: a GI safe and highly effective anti-inflammatory.

2009-02-01

We have been developing a family of phosphatidylcholine (PC)-associated NSAIDs, which appear to have improved GI safety and therapeutic efficacy in both rodent model systems and pilot clinical trials. As naproxen has been demonstrated to be associated with the lowest cardiovascular adverse events in comparison with both COX-2 selective inhibitors and conventional NSAIDs, we have been developing a Naproxen-PC formulation for evaluation in animal models and clinical trials. We have determined that an oil-based formulation of naproxen and triple strength soy lecithin provides excellent GI protection in both: 1) an acute NSAID-induced intestinal bleeding model in rats pretreated with L-NAME that are intragastrically administered a single dose of naproxen (at a dose of 50 mg/kg) vs the equivalent dose of Naproxen-PC; and 2) a more chronic model (at a naproxen dose of 25 mg/kg BID) in rats that have pre-existing hindpaw inflammation (induced with a intradermal injection of Complete Freund's Adjuvant/CFA). Both models demonstrate the superior GI safety of Naproxen-PC vs naproxen while this novel formulation had significant anti-inflammatory efficacy to reduce hindpaw edema and the generation of PGE(2) in the collected joint synovial fluid. Naproxen-PC appears to induce significantly less GI injury and bleeding in two rodent model systems while maintaining anti-inflammatory and COX-inhibitory activity.

We report a case that was successfully treated for massive lower gastrointestinal (LGI) bleeding due to a recurrent urinary bladder carcinoma. Treatment consisted of combination therapy including embolization of an inferior gluteal artery (IGA) pseudoaneurysm and low-dose arterial vasopressin infusion via a sigmoid artery (SA). A 57-year-old man presented with life-threatening sudden, massive LGI bleeding due to an obturator lymph node (LN) metastasis from a urinary bladder carcinoma. Computed tomography showed that the LN recurrence had invaded all the way to the sigmoid colon, and there was a pseudoaneurysm with extravasation inside the recurrence. An angiogram revealed a left IGA pseudoaneurysm. We therefore excluded the pseudoaneurysm by embolization with microcoils. Following this treatment the bleeding decreased, but intermittent LGI bleeding continued. Endoscopic examination showed the tumor with a huge ulcer inside the colonic lumen, and continuous oozing was confirmed. A second angiogram showed no recurrence of the IGA pseudoaneurysm and no apparent findings of bleeding. Then a 3F microcatheter was placed in the SA selectively using a coaxial catheter system, and vasopressin was infused at a rate 0.05 U/min for 12 h. Bleeding completely ceased 2 days later. There were no signs of ischemic gastrointestinal complications. Massive LGI bleeding has not recurred in 5 months.

Massive intraabdominal hemorrhage sometimes requires urgent hemostatic surgical intervention. In such cases, its rapid stabilization is crucial to reestablish a general hemodynamic status. We used an aortic occlusion balloon catheter in patients with massive intraabdominal hemorrhage occurring after hepato-pancreato-biliary surgery. An 8-French balloon catheter was percutaneously inserted into the aorta from the femoral artery, and the balloon was placed just above the celiac artery. Fifteen minutes inflation and 5 minutes deflation were alternated during surgery until the bleeding was surgically controlled. An aortic occlusion balloon catheter was inserted on 13 occasions in 10 patients undergoing laparotomy for hemostasis of massive hemorrhage. The aorta was successfully occluded on 12 occasions in nine patients. Both systolic pressure and heart rate were normalized during aortic occlusion, and the operative field became clearly visible after adequate suction of leaked blood. Bleeding sites were then easily found and controlled. Hemorrhage was successfully controlled in 7 of 10 patients (70%), and they were discharged in good condition. The aortic occlusion balloon catheter technique was effective for easily controlling massive intraabdominal bleeding by hemostatic procedure after hepato-pancreato-biliary surgery.

Purpose: To study the correlations between the dose distributions in the anorectal region and late GI symptoms in patients treated for localized prostate carcinoma. Methods and materials: Data from a randomized study were analyzed. In this trial, patients were treated with either rectangular or conformal fields with a dose of 66 Gy. Data concerning GI symptoms were collected from questionnaires of 197 patients. The distributions of the anorectal region were projected on maps, and the dose parameters were calculated. The incidences of complaints were studied as a function of the dose-area parameters and clinical parameters, using a proportional hazard regressionmore » model. Finally, we tested a series of dose parameters originating from different parts of the anorectal region. Results: Analyzing the total region, only a statistically significant dose-area effect relation for bleeding was found (p < 0.01). Defining subareas, we found effect relations for bleeding, soiling, fecal incontinence, and mucus loss. For bleeding and mucus loss, the strongest correlation was found for the dose received by the upper 70-80% of the anorectal region (p < 0.01). For soiling and fecal incontinence, we found the strongest association with the dose to the lower 40-50% (p < 0.05). Conclusion: We found evidence that complaints originate from specific regions of the irradiated lower GI tract. Bleeding and mucus loss are probably related to irradiation of the upper part of the rectum. Soiling and fecal incontinence are more likely related to the dose to the anal canal and the lower part of the rectum.« less

Gastrointestinal (GI) bleeding detection plays an essential role in wireless capsule endoscopy (WCE) examination. In this paper, we present a new approach for WCE bleeding detection that combines handcrafted (HC) features and convolutional neural network (CNN) features. Compared with our previous work, a smaller-scale CNN architecture is constructed to lower the computational cost. In experiments, we show that the proposed strategy is highly capable when training data is limited, and yields comparable or better results than the latest methods.

The authors report a case of upper gastrointestinal hemorrhage in a quadriplegic. The cause was a Mallory-Weiss tear, a previously unrecognized problem in these patients. The incidence of bleeding in patients with spinal cord injury is as high as 25 percent in the few reported series. We feel that with the increased risk of gastrointestinal bleeding in the spinal cord patient and the accompanying significant mortality, early endoscopy is essential for accurate diagnosis since clues to the presence, etiology, and severity of the bleeding are often lacking.

Portal hypertension (PH) is a common complication of chronic liver disease and results in esophageal and gastric variceal bleeding, which is associated with a high mortality rate. Measurement of the hepatic venous pressure gradient (HVPG) is considered the gold standard for diagnosing PH and estimating the risk of varices and bleeding. In contrast, upper gastrointestinal (GI) endoscopy (UGE) can reliably demonstrate the presence of varices and bleeding. Both measures are invasive, and HVPG is mainly restricted to tertiary centers. Therefore, the development of noninvasive methods of assessing the severity of PH and the risk of variceal bleeding is warranted. We retrospectively examined the correlation of spleen stiffness (SSM) and liver stiffness measurements (LSM) with the incidence of variceal bleeding among 143 patients who underwent combined liver and spleen elastography between 2013 and 2015. For 19 of 103 patients (16.8%), upper GI variceal bleeding was diagnosed and treated endoscopically. The median SSM of all patients was 35.3 kilopascals (kPa); the median LSM, 11.7 kPa. Patients with previous bleeding episodes had significantly higher SSM (75.0 kPa) and LSM (37.3 kPa) than those without a history of bleeding (SSM, 30.6 kPa; LSM, 8.2 kPa; p < 0.0001). Seventy-five patients (66.4%) underwent UGE in addition to SSM and LSM: 25 with no esophageal varices (EVs; SSM, 29.5 kPa; LSM, 11.4 kPa), 16 with EV grade 1 (SSM, 35.9 kPa; LSM, 33.4 kPa), 21 with EV grade 2 (SSM, 67.8 kPa; LSM, 27.0 kPa) and 13 with EV grade 3 (SSM, 75.0 kPa; LSM, 26.3 kPa). No statistically significant differences were found between respective grades of EV but were found between the presence and absence of varices. At a calculated cutoff level of 42.6 kPa (with application of 95% CI), SSM had sensitivity of 89% and specificity of 64% in determining the risk of bleeding, with a negative predictive value (NPV) of 0.97 (LSM sensitivity, 84%; LSM specificity, 80%; LSM NPV, 0.96 at LSM cutoff level of 20.8 kPa). When LSM (cutoff level, 20.8 kPa) and SSM (cutoff level, 42.6 kPa) were combined, the NPV was 1 (sensitivity, 100%; specificity, 55%). SSM and LSM as determined by FibroScan (a noninvasive method of detecting PH) is positively correlated with upper GI variceal bleeding (optimal SSM cutoff level, 42.6 kPa; optimal LSM cutoff level, 20.8 kPa). No patients with both SSM and LSM below cutoff levels had a history of bleeding complications. © 2016 S. Karger AG, Basel.

Among the causes of third trimester bleeding, the impact of placenta previa on cerebral palsy is not well known. To clarify the effect of maternal bleeding from placenta previa on cerebral palsy, and in particular when and how it occurs. A descriptive study. Sixty infants born to mothers with placenta previa in our regional population-based study of 160,000 deliveries from 1998 to 2012. Premature deliveries occurring at<26 weeks of gestation and placenta accreta were excluded. Prevalence of cystic periventricular leukomalacia (PVL) and cerebral palsy (CP). Five infants had PVL and 4 of these infants developed CP (1/40,000 deliveries). Acute and massive bleeding (>500g within 8h) occurred at around 30-31 weeks of gestation, and was severe enough to deliver the fetus. None of the 5 infants with PVL underwent antenatal corticosteroid treatment, and 1 infant had mild neonatal hypocapnia with a PaCO2 <25mmHg. However, none of the 5 PVL infants showed umbilical arterial acidemia with pH<7.2, an abnormal fetal heart rate monitoring pattern, or neonatal hypotension. Our descriptive study showed that acute and massive bleeding from placenta previa at around 30 weeks of gestation may be a risk factor for CP, and requires careful neonatal follow-up. The underlying process connecting massive placental bleeding and PVL requires further investigation. Copyright © 2014 Elsevier Ltd. All rights reserved.

Peptic ulcer bleeding can be fatal. Non-steroidal anti-inflammatory drugs (NSAIDs), corticosteroids and immunosuppressive agents are administered for long-term usage. The present study assessed the association between peptic ulcer bleeding and administration of NSAIDs, corticosteroids and immunosuppressive agents. Furthermore, the efficacy of lowering the risk of peptic ulcer bleeding with proton pump inhibitors (PPI) and histamine 2 receptor antagonists (H2RA) was evaluated. Medical records were retrospectively analyzed for patients subjected to an upper gastrointestinal (GI) endoscopy performed at the National Hospital Organization Shimoshizu Hospital (Yotsukaido, Japan) from October 2014 to September 2015. During this period, a total of 1,023 patients underwent an upper GI endoscopy. A total of 1,023 patients, including 431 males (age, 68.1±12.9 years) and 592 females (age, 66.4±12.3 years), who had been administered NSAIDs, corticosteroids, immunosuppressive agents, PPIs and H2RAs, were respectively enrolled. Endoscopic findings of the patients were reviewed and their data were statistically analyzed. Logistic regression analysis was used to determine the odds ratio of peptic ulcer bleeding for each medication; immunosuppressive agents had an odds ratio of 5.83, which was larger than that for NSAIDs (4.77). The Wald test was applied to confirm the correlation between immunosuppressive agents and peptic ulcer bleeding. Furthermore, χ 2 tests were applied to the correlation between peptic ulcer bleeding and administration of PPIs or H2RAs. Immunosuppressive agents had the largest χ 2 , and the P-value was 0.03. Administration of PPIs was significantly correlated with non-peptic ulcer bleeding (P=0.02); furthermore, a tendency toward non-peptic ulcer bleeding with administration of H2RA was indicated, but it was not statistically significant (P=0.12). In conclusion, immunosuppressive agents were correlated with peptic ulcer bleeding and PPIs were effective at lowering the risk of peptic ulcer bleeding.

Logistic regression analysis was used to determine the odds ratio of peptic ulcer bleeding for each medication; immunosuppressive agents had an odds ratio of 5.83, which was larger than that for NSAIDs (4.77). The Wald test was applied to confirm the correlation between immunosuppressive agents and peptic ulcer bleeding. Furthermore, χ2 tests were applied to the correlation between peptic ulcer bleeding and administration of PPIs or H2RAs. Immunosuppressive agents had the largest χ2, and the P-value was 0.03. Administration of PPIs was significantly correlated with non-peptic ulcer bleeding (P=0.02); furthermore, a tendency toward non-peptic ulcer bleeding with administration of H2RA was indicated, but it was not statistically significant (P=0.12). In conclusion, immunosuppressive agents were correlated with peptic ulcer bleeding and PPIs were effective at lowering the risk of peptic ulcer bleeding. PMID:28565788

Wireless capsule endoscopy (WCE) is the most advanced technology to visualize whole gastrointestinal (GI) tract in a non-invasive way. But the major disadvantage here, it takes long reviewing time, which is very laborious as continuous manual intervention is necessary. In order to reduce the burden of the clinician, in this paper, an automatic bleeding detection method for WCE video is proposed based on the color histogram of block statistics, namely CHOBS. A single pixel in WCE image may be distorted due to the capsule motion in the GI tract. Instead of considering individual pixel values, a block surrounding to that individual pixel is chosen for extracting local statistical features. By combining local block features of three different color planes of RGB color space, an index value is defined. A color histogram, which is extracted from those index values, provides distinguishable color texture feature. A feature reduction technique utilizing color histogram pattern and principal component analysis is proposed, which can drastically reduce the feature dimension. For bleeding zone detection, blocks are classified using extracted local features that do not incorporate any computational burden for feature extraction. From extensive experimentation on several WCE videos and 2300 images, which are collected from a publicly available database, a very satisfactory bleeding frame and zone detection performance is achieved in comparison to that obtained by some of the existing methods. In the case of bleeding frame detection, the accuracy, sensitivity, and specificity obtained from proposed method are 97.85%, 99.47%, and 99.15%, respectively, and in the case of bleeding zone detection, 95.75% of precision is achieved. The proposed method offers not only low feature dimension but also highly satisfactory bleeding detection performance, which even can effectively detect bleeding frame and zone in a continuous WCE video data.

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. evaluate the actual role and assess the diagnostic and therapeutic value of intraoperative enteroscopy in patients with obscure gastrointestinal bleeding. 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. with intraoperative enteroscopy a small bowel bleeding lesion was identified in 79% of patients and a gastrointestinal bleeding lesion in 94%. Small bowel findings included: angiodysplasia (n = 6), ulcers (n = 4), small bowel Dieulafoy´s lesion (n = 2), bleeding 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. 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.

Nowadays, capsule endoscopy (CE) is the first-line procedure after negative upper and lower gastrointestinal (GI) endoscopy for obscure gastrointestinal bleeding (OGIB). Approximately, two-thirds of patients undergoing CE for OGIB will have a small-bowel abnormality. However, several patients who underwent CE for OGIB had the source of their blood loss in the stomach or in the colon. The aim of the present study is to determine the incidence of bleeding lesions missed by the previous gastroscopy/colonoscopy with CE and to evaluate the indication to repeat a new complete endoscopic workup in subjects related to a tertiary center for obscure bleeding before CE. We prospectively reviewed data from 637/1008 patients underwent to CE for obscure bleeding in our tertiary center after performing negative gastroscopy and colonoscopy. CE revealed a definite or likely cause of bleeding in stomach in 138/637 patients (yield 21.7%) and in the colon in 41 patients (yield 6.4%) with a previous negative gastroscopy and colonoscopy, respectively. The lesions found were outside the small bowel in only 54/637 (8.5%) patients. In 111/138 patients, CE found lesions both in stomach and small bowel (small-bowel erosions in 54, AVMs in 45, active small-bowel bleeding in 4, neoplastic lesions in 3 and distal ileum AVMs in 5 patients). In 24/41 (58.5%) patients, CE found lesions both in small bowel and colon (multiple small-bowel erosions in 15; AVMs in 8 and neoplastic lesion in 1 patients. All patients underwent endoscopic therapy or surgery for their nonsmall-bowel lesions. Lesions in upper or lower GI tract have been missed in about 28% of patients submitted to CE for obscure bleeding. CE may play an important role in identifying lesions missed at conventional endoscopy.

We report the case of a patient with heterozygous sickle cell trait presenting with massive gross hematuria. Ureteroscopy revealed bleeding from the tip of papilla of the inferior calica and allowed us to tamponade the bleeding with a balloon ureteral dilator set (Cook(R) Urology). We show the value of the endourological approach in the conservative management of these patients at high risk of recurrent hematuria.

[Recommendation for the prevention and treatment of non-steroidal anti-inflammatory drug-induced gastrointestinal ulcers and its complications].

PubMed

2017-01-01

Non-steroidal anti-inflammatory drugs (NSAIDs) are a broad class of non glucocorticoid drugs which are extensively used in anti-inflammatory, analgesic, and antipyretic therapies. However, NSAIDs may cause many side effects, most commonly in gastrointestinal(GI) tract. Cardiovascular system, kidney, liver, central nervous system and hematopoietic system are also involved. NSAID-induced GI side effects not only endanger the patients' health, increase mortality, but also greatly increase the cost of medical care. Therefore, how to reduce GI side effects is of particular concern to clinicians. The Chinese Rheumatism Data Center(CRDC) and Chinese Systemic Lupus Erythematosus Treatment and Research Group(CSTAR) compose a "Recommendation for the prevention and treatment of non-steroidal anti-inflammatory drug-induced gastrointestinal ulcers and its complications" , as following: (1) GI lesions are the most common side effects of NSAIDs. (2) NSAID-induced GI side effects include gastritis, esophagitis, gastric and duodenal ulcers, bleeding, perforation and obstruction. (3) With the application of capsule endoscopy and small intestinal endoscopy, growing attention is being paid to the NASID-induced small intestine mucosa damage, which is mainly erosion and ulcer. (4) Risk factors related to NSAID-induced GI ulcers include: Helicobacter pylori (Hp) infection, age> 65 years, past history of GI ulcers, high doses of NSAIDs, multiple-drug combination therapy, and comorbidities, such as cardiovascular disease and nephropathy.(5) GI and cardiovascular function should be evaluated before using NSAIDs and gastric mucosal protective agents. (6) The risk of GI ulcers and complications caused by selective cyclooxygenase-2 (COX-2) inhibitors is less than that of non-selective COX-2 inhibitors. (7)Hp eradication therapy helps to cure GI ulcers and prevent recurrence when Hp infection is positive in NSAID-induced ulcers. (8) Proton pump inhibitor (PPI) is the first choice for the prevention and treatment of NSAID-induced GI injury. Gastric mucosal protective agents also suggested.(9) H 2 receptor antagonist (H 2 RA) can reduce the risk of NSAID-induced duodenal injury, however, the therapeutic effect of NSAID-induced gastric ulcer remains to be further confirmed. (10) Endoscopic treatment is the first recommendation for NSAID-induced peptic ulcers combined with upper GI bleeding, high-dose PPI effectively prevent rebleeding, reduce the possibility of surgery and mortality rate.

Concentration-dependent effect of hypocalcaemia on mortality of patients with critical bleeding requiring massive transfusion: a cohort study.

PubMed

Ho, K M; Leonard, A D

2011-01-01

Mortality of patients with critical bleeding requiring massive transfusion is high. Although hypothermia, acidosis and coagulopathy have been well described as important determinants of mortality in patients with critical bleeding requiring massive transfusion, the risk factors and outcome associated with hypocalcaemia in these patients remain uncertain. This cohort study assessed the relationship between the lowest ionised calcium concentration during the 24-hour period of critical bleeding and the hospital mortality of 352 consecutive patients, while adjusting for diagnosis, acidosis, coagulation results, transfusion requirements and use of recombinant factor VIIa. Hypocalcaemia was common (mean concentrations 0.77 mmol/l, SD 0.19) and had a linear; concentration-dependent relationship with mortality (odds ratio [OR] 1.25 per 0.1 mmol/l decrement, 95% confidence interval [CI]: 1.04 to 1.52; P = 0.02). Hypocalcaemia accounted for 12.5% of the variability and was more important than the lowest fibrinogen concentrations (10.8%), acidosis (7.9%) and lowest platelet counts (7.7%) in predicting hospital mortality. The amount of fresh frozen plasma transfused (OR 1.09 per unit, 95% CI: 1.02 to 1.17; P = 0.02) and acidosis (OR 1.45 per 0.1 decrement, 95% CI: 1.19 to 1.72; P = 0.01) were associated with the occurrence of severe hypocalcaemia (< 0.8 mmol/l). In conclusion, ionised calcium concentrations had an inverse concentration-dependent relationship with mortality of patients with critical bleeding requiring massive transfusion. Both acidosis and the amount of fresh frozen plasma transfused were the main risk factors for severe hypocalcaemia. Further research is needed to determine whether preventing ionised hypocalcaemia can reduce mortality of patients with critical bleeding requiring massive transfusion.

To estimate the risk of gastrointestinal (GI) bleeding associated with serotonin reuptake inhibitors (SSRIs) by level of kidney function. We conducted a cohort study using the Clinical Practice Research Datalink linked to Hospital Episode Statistics. We identified patients with chronic kidney disease (CKD) (estimated glomerular filtration rate [eGFR] <60 mL/min/1.73m 2 for ≥3 months), and a comparison group of patients without it. Patients with CKD were further classified as stage 3a (eGFR 45-59 mL/min/1.73m 2 ), 3b (30-44 mL/min/1.73m 2 ), and 4/5 (<30 mL/min/1.73m 2 ). We excluded prevalent SSRI users at cohort entry. Exposure was time-dependent SSRI prescription and outcome was first hospitalisation for GI bleeding. We estimated adjusted rate ratio (aRR) and rate difference (aRD) of GI bleeding comparing periods with and without SSRI prescription at each level of kidney function. The aRRs and aRDs were: (i) no CKD (N=202,121) aRR: 1.66 (95%CI 1.37-2.01), aRD: 2.0/1000 person-years (5.5 versus 3.5/1000 person-years in period with and without SSRIs); (ii) CKD stage 3a (N=153,316) aRR: 1.86 (1.62-2.15), aRD: 4.2/1000 person-years (8.3 versus 4.1/1000 person-years); (iii) CKD stage 3b (N=46,482) aRR: 1.61 (1.27-2.04), aRD: 4.8/1000 person-years (9.9 versus 5.1/1000 person-years); and (iv) CKD stage 4/5 (N=11,197) aRR: 1.84 (1.14-2.96), aRD: 7.9/1000 person-years (15.3 versus 7.4/1000 person-years). While there was no evidence of increase in the aRR (p-trend=0.922), there was strong evidence that the aRD increased as kidney function deteriorated (p-trend=0.001). While the relative risk was constant, the excess risk of GI bleeding associated with SSRIs markedly increased among patients with decreased kidney function. This article is protected by copyright.

Arterial hemorrhage from cesarean scar: a rare cause of recurring massive uterine bleeding and successful surgical management.

PubMed

Wang, Chun-Feng; Hu, Min

2015-02-01

Abnormal uterine bleeding and other gynecologic complications associated with a previous cesarean section scar are only recently being identified and described. Herein we report a rare case of a woman with recurring massive uterine bleeding after 2 cesarean sections. Curettage and hormone therapy were unsuccessfully used in an attempt to control the bleeding. After she was transferred to our hospital, she had another episode of vaginal bleeding that was successfully managed with oxytocin and hemostatic. Diagnostic hysteroscopy performed under anesthesia revealed an abnormal transected artery in the cesarean section scar with a thrombus visible. In the treatment at the beginning of laparoscopic management, we adopted temporary bilateral uterine artery occlusion with titanium clips to prevent massive hemorrhage. Secondly, with the aid of hysteroscopy, the bleeding site was opened, and then the cesarean scar was wedge resected and stitched interruptedly with 1-0 absorbable sutures. The postoperative recovery was uneventful. It would seem that the worldwide use of cesarean section delivery may contribute to the risk of gynecologic disturbances including some unrecognized and complex conditions as seen in this case.

Prognostic impact of gastrointestinal bleeding and expression of PTEN and Ki-67 on primary gastrointestinal stromal tumors

PubMed Central

2014-01-01

Background Prognostic indicators for gastrointestinal stromal tumors (GISTs) are under investigation. The latest risk classification criteria may still have room for improvement. This study aims to investigate prognostic factors for primary GISTs from three aspects, including clinicopathological parameters, immunohistochemical (IHC) expression of PTEN, and Ki-67 labeling index (LI), and attempts to find valuable predictors for the malignancy potential of primary GISTs. Methods Tumor samples and clinicopathological data from 84 patients with primary GISTs after R0 resection were obtained. Immunohistochemical analysis was performed based on tissue microarray (TMA) to estimate expression of PTEN and Ki-67 in tumor cells. Results The cut-off point of Ki-67 LI was determined as 1%, using a receiver operator characteristic test with a sensitivity of 71.7% and a specificity of 64.5%. Univariate analysis demonstrated the following factors as poor prognostic indicators for relapse-free survival (RFS) against a median follow-up of 40.25 months: gastrointestinal (GI) bleeding (P = 0.009), non-gastric tumor location (P = 0.001), large tumor size (P = 0.022), high mitotic index (P < 0.001), high cellularity (P = 0.012), tumor rupture (P = 0.013), absent or low expression of PTEN (P = 0.036), and Ki-67 LI >1% (P = 0.043). Gastrointestinal bleeding (hazard ratio, 3.85; 95% confidence interval, 1.63 to 9.10; P = 0.002) was a negative independent risk predictor in multivariate analysis, in addition to tumor size (P = 0.023), and mitotic index (P = 0.002). In addition, GI bleeding showed a good ability to predict recurrence potential, when included in our re-modified risk stratification criteria. Conclusions This study suggests that GI bleeding is an independent predictor of poor prognosis for RFS in primary GISTs. Expression of PTEN and Ki-67 are correlated with high risk potential and may predict early recurrence in univariate analysis. PMID:24712384

Peptic ulcers are the leading cause of upper gastrointestinal (GI) bleeding. The aim of this study was the evaluation of the recent clinical practice in drug therapy and endoscopic treatment of ulcer bleedings in Germany and to compare the results with the medical standard. A structured questionnaire (cross-sectional study) was sent to 1371 German hospitals that provide an emergency service for upper GI bleeding. The project was designed similar to a nationwide inquiry in France in 2001. Forty-four questions concerning the following topics were asked: hospital organisation, organisation of emergency endoscopy service, endoscopic and drug therapy of ulcer bleeding, endoscopic treatment of variceal bleeding. Return of the questionnaires was closed in August 2004. Response rate was 675 / 1371 (49 %). Mean hospitals size was < 200 beds, 49 % (n = 325) had basic care level. 92 % provided a 24-hour endoscopy service, specialized nurses were available in 75 %. Fiberscopes were used only in 15 %. A mean of 10 +/- 12 (range: 0 - 160) bleeding cases/month were treated, 6 +/- 6 cases per month (60 %) were ulcer bleedings. Endoscopy was performed in 72 % immediately after stabilization but in all cases within 24 hours. The Forrest classification was used in 99 % whereas prognostic scores were applied only in 3 %. Forrest Ia,/Ib/IIa/IIb/IIc/III ulcers were indications for endoscopic therapy in 99 %/ 99 %/ 90 %/ 58 %/ 4 %/ 2 % respectively. Favoured initial treatment was injection (diluted epinephrine, mean volume 17 +/- 13 mL/lesion) followed by clipping. In re-bleedings, 93 % tried endoscopic treatment again. Scheduled re-endoscopy was performed in 63 %. PPI were used in 99.6 %, 85 % administered standard dose twice daily. PPI administration was changed from intravenous to oral with the end of fasting in nearly all hospitals. PPI administration schemes can be improved. Indications for Helicobacter pylori eradication followed rational principles. Medical and endoscopic treatment of bleeding ulcers reached a high standard, although some therapeutic strategies leave room for improvement. Bigger hospitals tend to be closer to the medical standard.

The purpose of this study is to determine the effect of using autologous platelet rich plasma (PRP) in patients having massive hemoptysis within a period of one week. This is a prospective cohort study involving 20 consecutive patients admitted who met the criteria for massive hemoptysis from July to October 2011. After stabilizing the patient, fiberoptic bronchoscopy (FOB) was performed for localization of bleeding within 6 hours from diagnosis. A 50mL of blood was extracted from the patient whom was to be used for autologous PRP concentrate. After identifying the anatomic site of bleeding, autologous PRP concentrate was instilled on the affected bronchus and was allowed to stay for 5 minutes after instillation. Patients were then monitored from the time the bleeding stopped in the first 24 hours, 2 days and 7 days respectively. Mean age of the study population with massive hemoptysis was 47 years old (SD 17.3). Majority of cases were male 18 out of 20 (90%) and smokers 14 (70%) with a normal BMI (75%). Identification of bleeding site was more commonly seen on the right upper lobe 9 out of 20 (45%). Overall, 14 out of 20 patients (70%) were reported to have stopped bleeding immediately. Subsequent hospital days showed that 8 out of 20 patients (40%) had no hemoptysis. However, one [1] post-tuberculosis (TB) bronchiectatic patient had recurrence of massive hemoptysis, approximately 250 mL per expectorate, expired within the 7 days observation and one patient had lobectomy on the 2nd day. The rest had non-massive hemoptysis wherein their expectorations were only streaks of blood. Moreover, there was one [1] patient who had recurrence of massive hemoptysis 1 week after autologous PRP infusion and was eventually intubated. Majority of the subjects, eleven [11] were diagnosed to have post-TB bronchiectasis. The rest of the patients were worked-up prior to operation. Overall, it was observed that the use of autologous PRP was able to stop bleeding in 40% of the study population for 7 days. It is simple and easy to reproduce as it was directly extracted from the patient.

The efficacy of aspirin in primary and secondary prevention of cardiovascular diseases has been convincingly demonstrated. Gastrointestinal (GI) adverse effects with aspirin may lead to poor adherence and/or discontinuation of treatment. Proton pump inhibitors (PPIs) have been used for more than 20 years as the first choice for treating peptic ulcers and their bleeding complications, gastroesophageal reflux disease, non-steroidal anti-inflammatory drug-induced GI lesions and dyspepsia. Adherence becomes a major concern when aspirin is co-prescribed with PPIs to prevent GI adverse effects. Combining aspirin and PPIs into one tablet is an effective approach to address aspirin-related GI adverse effects and increase adherence to aspirin therapy for the prevention of cardiovascular diseases.

Wireless capsule endoscopy: perspectives beyond gastrointestinal bleeding.

Wireless capsule endoscopy (CE) is a technology developed for the endoscopic exploration of the small bowel. The first capsule model was approved by the Food and Drug Administration in 2001, and its first and essential indication was occult gastrointestinal (GI) bleeding. Over subsequent years, this technology has been refined to provide superior resolution, increased battery life, and capabilities to view different parts of the GI tract. Indeed, cases for which CE proved useful have increased significantly over the last few years, with new indications for the small bowel and technical improvements that have expanded its use to other parts of the GI tract, including the esophagus and colon. The main challenges in the development of CE are new devices with the ability to provide therapy, air inflation for a better vision of the small bowel, biopsy sampling systems attached to the capsule and the possibility to guide and move the capsule with an external motion control. In this article we review the current and new indications of CE, and the evolving technological changes shaping this technology, which has a promising potential in the coming future of gastroenterology.

Massive haematuria is a life-threatening condition, demanding immediate management of bleeding. The mortality is very high in the case of delayed management of bleeding, especially in elderly patients with concomitant comorbidity. The treatment options of haematuria are wide, and depend on underlying conditions. However, therapeutic choices are limited in the presence of massive and intractable haematuria caused by disseminated intravascular coagulation (DIC). Ankaferd blood stopper (ABS) is a novel, commercially available, haemostatic agent, which has been approved by the Ministry of Health for local use in Turkey. Here, for the first time in the literature, we report a case of diffuse intravesical bleeding stopped by intravesical use of ABS in a 72-year-old man, haemodialysis patient complicated with sepsis and DIC.

Essentials The evidence on how to manage life-threatening pregnancy-related pulmonary embolism (PE) is scarce. We systematically reviewed all available cases of (sub)massive PE until December 2016. Thrombolysis in such severe PE was associated with a high maternal survival (94%). The major bleeding risk was much greater in the postpartum (58%) than antepartum period (18%). Background Massive pulmonary embolism (PE) during pregnancy or the postpartum period is a rare but dramatic event. Our aim was to systematically review the evidence to guide its management. Methods We searched Pubmed, Embase, conference proceedings and the RIETE registry for published cases of severe (submassive/massive) PE treated with thrombolysis, percutaneous or surgical thrombectomy and/or extracorporeal membrane oxygenation (ECMO), occurring during pregnancy or within 6 weeks of delivery. Main outcomes were maternal survival and major bleeding, premature delivery, and fetal survival and bleeding. Results We found 127 cases of severe PE (at least 83% massive; 23% with cardiac arrest) treated with at least one modality. Among 83 women with thrombolysis, survival was 94% (95% CI, 86-98). The risk of major bleeding was 17.5% during pregnancy and 58.3% in the postpartum period, mainly because of severe postpartum hemorrhages. Fetal deaths possibly related to PE or its treatment occurred in 12.0% of cases treated during pregnancy. Among 36 women with surgical thrombectomy, maternal survival and risk of major bleeding were 86.1% (95% CI, 71-95) and 20.0%, with fetal deaths possibly related to surgery in 20.0%. About half of severe postpartum PEs occurred within 24 h of delivery. Conclusions Published cases of thrombolysis for massive PE during pregnancy and the postpartum period suggest a high maternal and fetal survival (94% and 88%). In the postpartum period, given the high risk of major bleeding with thrombolysis, other therapeutic options (catheter [or surgical] thrombectomy, ECMO) may be considered if available. © 2017 International Society on Thrombosis and Haemostasis.

Objective To identify factors associated with massive postpartum bleeding in pregnancies complicated by incomplete placenta previa located on the posterior uterine wall. Methods A retrospective case-control study was performed. We identified 210 healthy singleton pregnancies with incomplete placenta previa located on the posterior uterine wall, who underwent elective or emergency cesarean section after 24 weeks of gestation between January 2006 and April 2016. The cases with intraoperative blood loss (≥2,000 mL) or transfusion of packed red blood cells (≥4) or uterine artery embolization or hysterectomy were defined as massive bleeding. Results Twenty-three women experienced postpartum profuse bleeding (11.0%). After multivariable analysis, 4 variables were associated with massive postpartum hemorrhage (PPH): experience of 2 or more prior uterine curettage (adjusted odds ratio [aOR], 4.47; 95% confidence interval [CI], 1.29 to 15.48; P=0.018), short cervical length before delivery (<2.0 cm) (aOR, 7.13; 95% CI, 1.01 to 50.25; P=0.049), fetal non-cephalic presentation (aOR, 12.48; 95% CI, 1.29 to 121.24; P=0.030), and uteroplacental hypervascularity (aOR, 6.23; 95% CI, 2.30 to 8.83; P=0.001). Conclusion This is the first study of cases with incomplete placenta previa located on the posterior uterine wall, which were complicated by massive PPH. Our findings might be helpful to guide obstetric management and provide useful information for prediction of massive PPH in pregnancies with incomplete placenta previa located on the posterior uterine wall.

Continuous-flow left ventricular assist devices (CF-LVAD) have become the standard of care for patients with end stage heart failure. Device reliability has increased, bringing the potential for VAD, compared to transplant, into debate. However, complications continue to limit VADs as first line therapy. Bleeding is a major morbidity. A debate exists as to the difference in bleeding profile between the major centrifugal and axial flow devices. We hypothesized that there would be similar adverse bleeding event profiles between the 2 major CF-LVADs. We retrospectively investigated isolated CF LVADs performed at our institution between July 2010 and July 2015: HeartMateII (HMII, n = 105) and HeartWare (HVAD, n = 34). We reviewed demographic, perioperative and short- and long-term outcomes. There was no significant difference in demographics or comorbidities. There was a low incidence of gastrointestinal (GI) bleed 3.9% in HMII and 2.9% in HVAD (p = 0.78). Preoperatively, the cohorts did not differ in coagulation measures (p = 0.95). Within the post-operative period, there was no difference in product transfusion: red blood cells (p = 0.10), fresh frozen plasma (p = 0.19), and platelets (p = 0.89). Post-operatively, a higher but not significantly different number of HMII patients returned to the operating room for bleeding (n = 27) compared to HVAD (n = 6, p = 0.35). There was no difference in rates of stroke (p = 0.65), re-intubation (p = 0.60), driveline infection (p = 0.05), and GI bleeding (p = 0.31). The patients had equivalent ICU LOS (p = 0.86) and index hospitalization LOS (p = 0.59). We found no difference in the rate of bleeding complications between the current commercially available axial and centrifugal flow devices.

CHOBS: Color Histogram of Block Statistics for Automatic Bleeding Detection in Wireless Capsule Endoscopy Video

PubMed Central

Ghosh, Tonmoy; Wahid, Khan A.

2018-01-01

Wireless capsule endoscopy (WCE) is the most advanced technology to visualize whole gastrointestinal (GI) tract in a non-invasive way. But the major disadvantage here, it takes long reviewing time, which is very laborious as continuous manual intervention is necessary. In order to reduce the burden of the clinician, in this paper, an automatic bleeding detection method for WCE video is proposed based on the color histogram of block statistics, namely CHOBS. A single pixel in WCE image may be distorted due to the capsule motion in the GI tract. Instead of considering individual pixel values, a block surrounding to that individual pixel is chosen for extracting local statistical features. By combining local block features of three different color planes of RGB color space, an index value is defined. A color histogram, which is extracted from those index values, provides distinguishable color texture feature. A feature reduction technique utilizing color histogram pattern and principal component analysis is proposed, which can drastically reduce the feature dimension. For bleeding zone detection, blocks are classified using extracted local features that do not incorporate any computational burden for feature extraction. From extensive experimentation on several WCE videos and 2300 images, which are collected from a publicly available database, a very satisfactory bleeding frame and zone detection performance is achieved in comparison to that obtained by some of the existing methods. In the case of bleeding frame detection, the accuracy, sensitivity, and specificity obtained from proposed method are 97.85%, 99.47%, and 99.15%, respectively, and in the case of bleeding zone detection, 95.75% of precision is achieved. The proposed method offers not only low feature dimension but also highly satisfactory bleeding detection performance, which even can effectively detect bleeding frame and zone in a continuous WCE video data.

We present two patients developing intraoperative massive bleeding and showed ischemic changes in the electrocardiogram and circulatory collapse accompanied by severe anemia owing to the delay of red blood cell concentrate transfusion. One patient underwent hepatectomy and the other pancreaticoduodenectomy. Their lowest hemoglobin concentration was around 2 g x dl(-1), and they showed ischemic changes in the electrocardiogram and severe decreases in blood pressure. The former received compatible red blood cell concentrate and the latter received uncrossmatched same blood group red blood cell concentrate immediately, and their electrocardiogram and blood pressure quickly improved. To avoid life-threatening anemia, emergency red blood cell concentrate transfusion including compatible different blood group transfusion should be applied for intraoperative massive bleeding.

Severe gastrointestinal (GI) hemorrhage is a rare complication of Crohn’s disease (CD). Although several surgical and non-surgical approaches have been described over the last 2 decades this complication still poses significant diagnostic and therapeutic challenges. Given the relative infrequency of severe bleeding in CD, available medical literature on this topic is mostly in the form of retrospective case series and reports. In this article we review the risk factors, diagnostic modalities and treatment options for the management of CD presenting as GI hemorrhage. PMID:27122659

We present the case of a 37-year-old nulliparous woman in whom acute massive uterine bleeding during dienogest therapy was successfully treated using intrauterine balloon tamponade. Abnormal uterine bleeding and several cases of profuse bleeding causing severe anemia in association with dienogest therapy have been reported, but this is the first reported case involving hypovolemic shock. While successful control of postpartum hemorrhage with intrauterine balloon tamponade has been well described, applications for non-obstetric bleeding, particularly in the presence of underlying diseases, such as adenomyosis, have only rarely been reported. This procedure can be easily, promptly, and safely implemented without analgesia, anesthesia, or laparotomy; it can be used with a minimally dilated external cervical os or narrow uterine cavity; and it can preserve fertility. © 2012 The Authors.

We report herein the case of a patient successfully treated by transhepatic portal venous stent placement for malignant portal vein obstruction with associated gastric and small bowel varices and repeated gastrointestinal bleeding. CT angiography and portography showed severe portal vein obstruction from recurrent pancreatic cancer 15 months following pancreaticoduodenectomy with tumor encasement and dilated collateral veins throughout the gastric and proximal small bowel wall as the suspected cause of the GI bleeding. Successful transhepatic endovascular stent placement of the splenic vein at the portal vein confluence followed by balloon dilation was performed with immediate decompression of the gastric and small bowel varices and relief of GI hemorrhage in this patient until his death four months later. The treatment for patients with this dilemma can prove to be difficult, but as we have shown endovascular stenting of the portal system is an effective treatment option. PMID:19826629

Preliminary studies on a new topical hemostatic agent, TC-325, have shown its safety and effectiveness in treating active upper gastrointestinal (GI) bleeding. However, to date there have been no randomized trials comparing TC-325 with the conventional combined technique (CCT). Our pilot study aimed to compare the efficacy and safety of TC-325 with those of CCT in treating peptic ulcers with active bleeding or high-risk stigmata. This was a comparative randomized study of patients with upper GI bleeding who had Forrest class I, IIA or IIB ulcers. Altogether 20 patients with a mean age of 70 years (range 23-87 years) were recruited, including 16 men, with a mean hemoglobin of 97 g/L. Initial hemostasis was successful in 19 (95.0%) patients, including 90.0% (9/10) in the TC-325 group and 100% (10/10) in the CCT group. TC-325 monotherapy failed to stop bleeding in a patient with Forrest IB posterior duodenal wall ulcer. Rebleeding was seen in 33.3% (3/9) of the patients in the TC-325 group and 10.0% (1/10) in the CCT group. One patient required angio-embolization therapy while three had successful conventional endotherapy. Two patients from the TC-325 group had serious adverse events that were not procedure- or therapy-related. In patients with Forrest IIA or IIB ulcers, five received TC-325 monotherapy; none had rebleeding. Our pilot study showed that TC-325 has a tendency towards a higher rebleeding rate than CCT, when treating actively bleeding ulcers. Larger trials are necessary for definitive results. © 2017 Chinese Medical Association Shanghai Branch, Chinese Society of Gastroenterology, Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine and John Wiley & Sons Australia, Ltd.

Schemas to identify bleeding-related hospitalizations in claims data differ in billing codes used and coding positions allowed. We assessed agreement across bleeding-related hospitalization coding schemas for claims analyses of nonvalvular atrial fibrillation (NVAF) patients on oral anticoagulation (OAC). We hypothesized that prior coding schemas used to identify bleeding-related hospitalizations in claim database studies would provide varying levels of agreement in incidence rates. Within MarketScan data, we identified adults, newly started on OAC for NVAF from January 2012 to June 2015. Billing code schemas developed by Cunningham et al., the US Food and Drug Administration (FDA) Mini-Sentinel program, and Yao et al. were used to identify bleeding-related hospitalizations as a surrogate for major bleeding. Bleeds were subcategorized as intracranial hemorrhage (ICH), gastrointestinal (GI), or other. Schema agreement was assessed by comparing incidence, rates of events/100 person-years (PYs), and Cohen's kappa statistic. We identified 151 738 new-users of OAC with NVAF (CHA2DS2-VASc score = 3, [interquartile range = 2-4] and median HAS-BLED score = 3 [interquartile range = 2-3]). The Cunningham, FDA Mini-Sentinel, and Yao schemas identified any bleeding-related hospitalizations in 1.87% (95% confidence interval [CI]: 1.81-1.94), 2.65% (95% CI: 2.57-2.74), and 4.66% (95% CI: 4.55-4.76) of patients (corresponding rates = 3.45, 4.90, and 8.65 events/100 PYs). Kappa agreement across schemas was weak-to-moderate (κ = 0.47-0.66) for any bleeding hospitalization. Near-perfect agreement (κ = 0.99) was observed with the FDA Mini-Sentinel and Yao schemas for ICH-related hospitalizations, but agreement was weak when comparing Cunningham to FDA Mini-Sentinel or Yao (κ = 0.52-0.53). FDA Mini-Sentinel and Yao agreement was moderate (κ = 0.62) for GI bleeding, but agreement was weak when comparing Cunningham to FDA Mini-Sentinel or Yao (κ = 0.44-0.56). For other bleeds, agreement across schemas was minimal (κ = 0.14-0.38). We observed varying levels of agreement among 3 bleeding-related hospitalizations schemas in NVAF patients. © 2018 Wiley Periodicals, Inc.

Metastatic involvement of the gastrointestinal (GI) tract secondary to breast cancer (BC) is rare and usually occurs in patients with lobular BC. We report 2 cases with GI presentations of metastatic BC. In the first case endoscopy and endoscopic ultrasonography because of abdominal discomfort, tenesmus and rectal bleeding demonstrated liver, gastric and rectal metastases with histological and immunohistological patterns of metastatic lobular BC. In the second case gastric involvement, endoscopically presented as a solid nodular lesion in the gastric body and fundus with involvement of the gastro-esophageal junction, was established with clinical symptoms of solid food dysphagia and dyspepsia; the metastatic infiltration from ductal BC was proven histologically and immunohistochemically. The GI metastases were presented 5 and 7 years after radical mastectomy because of lobular and ductal BC respectively. The cases are of interest with a feature of liver and GI metastases in double sites (stomach and rectum) from lobular BC, as well as solid gastric metastasis from ductal BC. They illustrate the need for special attention to GI metastatic disease in patients with invasive BC who present with non-specific GI symptoms.

Massive lower gastrointestinal bleeding is a significant and expensive problem that requires methodical evaluation, management, and treatment. After initial resuscitation, care should be taken to localize the site of bleeding. Once localized, lesions can then be treated with endoscopic or angiographic interventions, reserving surgery for ongoing or recurrent bleeding. PMID:24294124

In this paper, we present a novel and clinically valuable software platform for automatic ulcer detection on gastrointestinal (GI) tract from Capsule Endoscopy (CE) videos. Typical CE videos take about 8 hours. They have to be reviewed manually by physicians to detect and locate diseases such as ulcers and bleedings. The process is time consuming. Moreover, because of the long-time manual review, it is easy to lead to miss-finding. Working with our collaborators, we were focusing on developing a software platform called GISentinel, which can fully automated GI tract ulcer detection and classification. This software includes 3 parts: the frequency based Log-Gabor filter regions of interest (ROI) extraction, the unique feature selection and validation method (e.g. illumination invariant feature, color independent features, and symmetrical texture features), and the cascade SVM classification for handling "ulcer vs. non-ulcer" cases. After the experiments, this SW gave descent results. In frame-wise, the ulcer detection rate is 69.65% (319/458). In instance-wise, the ulcer detection rate is 82.35%(28/34).The false alarm rate is 16.43% (34/207). This work is a part of our innovative 2D/3D based GI tract disease detection software platform. The final goal of this SW is to find and classification of major GI tract diseases intelligently, such as bleeding, ulcer, and polyp from the CE videos. This paper will mainly describe the automatic ulcer detection functional module.

Different oral anticoagulants may be associated with gastrointestinal bleeding (GIB) from different locations or mucosal lesions. We aimed to test this hypothesis. Two blinded gastroenterologists independently analyzed source documents from the randomized evaluation of long-term anticoagulant therapy (RE-LY) trial of dabigatran 150 mg BID (D150), dabigatran 110 mg BID (D110) versus warfarin in non-valvular atrial fibrillation (NVAF). Major GIB events (total n = 546) and life-threatening GIB events (n = 258) were more common with D150 versus warfarin (RR 1.57 [1.28-1.92] and RR 1.62 [1.20-2.18], respectively) and similar for D110 compared to warfarin (RR 1.11 [0.89-1.38] and RR 1.16 [0.84-1.61], respectively). Fatal bleeding was similarly rare across treatment groups. Lower GI major bleeding and life-threatening bleeding were more common with D150 compared to warfarin (RR 2.23 [1.47, 3.38] and RR 2.64 [1.36, 5.13], respectively) and with D110 compared to warfarin (RR 1.78 [1.16, 2.75] and RR 2.00 [1.00, 4.00], respectively). MGIB from colonic angiodysplasia was increased with dabigatran versus warfarin (P < 0.01 for both dose comparisons). Subacute and chronic MGIB events were more common with D150 than with warfarin (RR 1.72 [1.06, 2.78] and RR 1.66 [1.12, 2.45], respectively), as were hematochezia or melena (RR 1.67 [1.18, 2.36] and RR 1.72 [1.20, 2.47], respectively). In a chronic NVAF population, D150 but not D110 is associated with increased major and life-threatening GI bleeding in comparison with warfarin. At both dabigatran doses, increased bleeding from the colorectum, in particular from angiodysplasia, is seen.

Massive hemoptysis is a life-threatening condition, and the major source of bleeding in this condition is the bronchial circulation. Bronchial artery embolization is a safe and effective treatment for controlling hemoptysis. However, the sites of origin of the bronchial arteries (BAs) have numerous anatomical variations, which can result in a technical challenge to identify a bleeding artery. We present a rare case of a left inferior BA that originated from the left gastric artery in a patient with recurrent massive hemoptysis caused by bronchiectasis. The aberrant BA was embolized, and hemoptysis has been controlled for 8 months.

Abstract Background Massive bleeding during liver transplantation (LT) is difficult to manage surgical event. Perihepatic packing (PP) and temporary abdominal closure (TAC) with delayed biliary reconstruction (DBR) can be applied in these circumstances. Method A prospective database of LT in a major transplant center was analyzed to identify patients with massive uncontrollable bleeding during LT that was resolved by PP, TAC, and DBR. Results From January 2009 to July 2013, 20 (3.6%) of 547 patients who underwent LT underwent DBR. Mean intraoperative blood loss was 20,500 ml at the first operation. The DBR was performed with a mean of 55.2 h (16–110) after LT. Biliary reconstruction included duct‐to‐duct (n = 9) and hepatico‐jejunostomy (n = 11). Complications occurred in eight patients and included portal vein thrombosis, cholangitis, severe bacteremia, pneumonia. There was one in‐hospital death. In the follow‐up of 18 to 33 months we have seen one patient died 9 months after transplantation. The remaining 18 patients are alive and well. Conclusions In case of massive uncontrollable bleeding and bowel edema during LT, the combined procedures of PP, TAC, and DBR offer an alternatively surgical option to solve the tough situation.

House, Tyler; Webb, Patrick; Baarson, Chad

2017-01-01

Duodenal variceal bleeding is an uncommon complication of portal hypertension that can easily go unrecognized and reach mortality rates as high as 40%. Cirrhosis is the most common cause of duodenal varices. In most cases, duodenal varices occur concomitantly with esophageal varices, further complicating identification with initial endoscopy. Although many modalities have been explored with respect to management and treatment approaches, guidelines have yet to be established owing to the infrequency in which bleeding occurs from ectopic duodenal varices. We present a case of massive duodenal variceal hemorrhage that highlights the complexity of initial diagnosis and ultimately required a transesophageal intrahepatic portosystemic shunt with coil embolization for control of bleeding.

To assess the effects of stress ulcer prophylaxis (SUP) versus placebo or no prophylaxis on all-cause mortality, gastrointestinal (GI) bleeding and hospital-acquired pneumonia in adult critically ill patients in the intensive care unit (ICU). We performed a systematic review using meta-analysis and trial sequential analysis (TSA). Eligible trials were randomised clinical trials comparing proton pump inhibitors or histamine 2 receptor antagonists with either placebo or no prophylaxis. Two reviewers independently assessed studies for inclusion and extracted data. The Cochrane Collaboration methodology was used. Risk ratios/relative risks (RR) with 95% confidence intervals (CI) were estimated. The predefined outcome measures were all-cause mortality, GI bleeding, and hospital-acquired pneumonia. Twenty trials (n = 1,971) were included; all were judged as having a high risk of bias. There was no statistically significant difference in mortality (fixed effect: RR 1.00, 95% CI 0.84-1.20; P = 0.87; I(2) = 0%) or hospital-acquired pneumonia (random effects: RR 1.23, 95% CI 0.86-1.78; P = 0.28; I(2) = 19%) between SUP patients and the no prophylaxis/placebo patients. These findings were confirmed in the TSA. With respect to GI bleeding, a statistically significant difference was found in the conventional meta-analysis (random effects: RR 0.44, 95% CI 0.28-0.68; P = 0.01; I(2) = 48%); however, TSA (TSA adjusted 95% CI 0.18-1.11) and subgroup analyses could not confirm this finding. This systematic review using meta-analysis and TSA demonstrated that both the quality and the quantity of evidence supporting the use of SUP in adult ICU patients is low. Consequently, large randomised clinical trials are warranted.

Clinical features of gastroduodenal injury associated with long-term low-dose aspirin therapy

Low-dose aspirin (LDA) is clinically used for the prevention of cardiovascular and cerebrovascular events with the advent of an aging society. On the other hand, a very low dose of aspirin (10 mg daily) decreases the gastric mucosal prostaglandin levels and causes significant gastric mucosal damage. The incidence of LDA-induced gastrointestinal mucosal injury and bleeding has increased. It has been noticed that the incidence of LDA-induced gastrointestinal hemorrhage has increased more than that of non-aspirin non-steroidal anti-inflammatory drug (NSAID)-induced lesions. The pathogenesis related to inhibition of cyclooxygenase (COX)-1 includes reduced mucosal flow, reduced mucus and bicarbonate secretion, and impaired platelet aggregation. The pathogenesis related to inhibition of COX-2 involves reduced angiogenesis and increased leukocyte adherence. The pathogenic mechanisms related to direct epithelial damage are acid back diffusion and impaired platelet aggregation. The factors associated with an increased risk of upper gastrointestinal (GI) complications in subjects taking LDA are aspirin dose, history of ulcer or upper GI bleeding, age > 70 years, concomitant use of non-aspirin NSAIDs including COX-2-selective NSAIDs, and Helicobacter pylori (H. pylori) infection. Moreover, no significant differences have been found between ulcer and non-ulcer groups in the frequency and severity of symptoms such as nausea, acid regurgitation, heartburn, and bloating. It has been shown that the ratios of ulcers located in the body, fundus and cardia are significantly higher in bleeding patients than the ratio of gastroduodenal ulcers in patients taking LDA. Proton pump inhibitors reduce the risk of developing gastric and duodenal ulcers. In contrast to NSAID-induced gastrointestinal ulcers, a well-tolerated histamine H2-receptor antagonist is reportedly effective in prevention of LDA-induced gastrointestinal ulcers. The eradication of H. pylori is equivalent to treatment with omeprazole in preventing recurrent bleeding. Continuous aspirin therapy for patients with gastrointestinal bleeding may increase the risk of recurrent bleeding but potentially reduces the mortality rates, as stopping aspirin therapy is associated with higher mortality rates. It is very important to prevent LDA-induced gastroduodenal ulcer complications including bleeding, and every effort should be exercised to prevent the bleeding complications. PMID:23555156

Cost-effectiveness of using recombinant activated factor VII as an off-label rescue treatment for critical bleeding requiring massive transfusion.

Recombinant activated factor VII (rFVIIa) is widely used as an off-label rescue treatment for patients with nonhemophilic critical bleeding. Using data from the intensive care unit, transfusion service, and death registry, the long-term survival after using rFVIIa and the associated cost per life-year gained in a consecutive cohort of patients with critical bleeding requiring massive transfusion (≥ 10 red blood cell [RBC] units in 24 hr) were assessed. rFVIIa was only used as a lifesaving treatment when conventional measures had failed. Of the 353 patients with critical bleeding requiring massive transfusion, 81 (23%) required rFVIIa as a lifesaving rescue treatment. The patients requiring rFVIIa received a greater number of transfusions (number of units: RBCs, 18 vs. 12; fresh-frozen plasma, 16 vs. 10; platelets, 4 vs. 2; p < 0.001) and had a shorter survival time (24 months vs. 33 months; p = 0.002) than those who did not require rFVIIa. The total cost per life-year gained of massive transfusion and incremental cost of rFVIIa as a lifesaving treatment were US$1,148,000 (£711,760; 95% confidence interval [CI], US$825,000-US$1,471,000) and US$736,000 (£456,320; 95% CI, US$527,000-US$945,000), respectively. The incremental costs of rFVIIa increased with severity of illness and transfusion requirement and were greater than the usual acceptable cost-effective limit (

Objectives Gingival bleeding following twice-daily use of 0.2% w/v chlorhexidine digluconate mouthrinse with and without alcohol (0.2% CHX-alcohol; 0.2% CHX-alcohol-free, respectively) and brushing with a standard fluoride toothpaste was compared to brushing alone. Methods Three hundred and nineteen subjects with mild-to-moderate gingivitis (with ≥16 gradable permanent teeth including four molars, bleeding after brushing and ≥20 bleeding sites) completed this randomised, examiner-blinded, parallel-group study. A prophylaxis was performed at baseline. Gingival Severity Index (GSI; primary objective), Gingival Index (GI) and Plaque Index (PI) were assessed at baseline and after 6 weeks of treatment. Adverse events (AEs) were recorded throughout the study. Results Between treatment differences at week 6 demonstrated significantly lower GSI for the 0.2% CHX-alcohol and 0.2% CHX-alcohol-free groups compared to brushing alone (primary endpoint; treatment difference −0.061 [95% CI −0.081, −0.041] and −0.070 [95% CI −0.090, −0.050], respectively; both p <0.0001). There were also significant reductions in GI and PI for the 0.2% CHX-alcohol and 0.2% CHX-alcohol-free groups compared to brushing alone (all p <0.0001). The proportion of subjects reporting ≥1 treatment-related adverse events (TRAEs) was 27.8% (0.2% CHX-alcohol), 24.8% (0.2% CHX-alcohol-free) and 3.7% (brushing alone). Conclusions Chlorhexidine mouthrinse with or without alcohol as an adjunct to brushing with regular fluoride toothpaste significantly reduces bleeding scores, plaque and gingival inflammation compared to brushing alone. TRAEs are characteristic of those associated with the use of chlorhexidine and are similar for both mouthrinses. PMID:26271869

[Massive bleeding symptoms in two patients with factor V inhibitor and antiphospholipid antibodies after treatment with ciprofloxacin].

The development of factor V inhibitor is very rare, especially in combination with antiphospholipid antibodies. The paper describes the course of two patients with factor V inhibitor, antiphospholipid antibodies and massive bleeding symptoms after treatment with ciprofloxacin. At that time, ciprofloxacin was the only new drug given. DIAGNOSIS AND CLINICAL COURSE: First changes of the coagulation system were detected 4 days after start of treatment. In one case, occurrence was transient, and normalization was observed after terminating ciprofloxacin treatment. The other case ended with massive muscular and visceral bleedings and cardiovascular failure. Factor V inhibitor and antiphospholipid antibodies could be demonstrated even after termination of ciprofloxacin therapy. The association of treatment with ciprofloxacin and development of factor V inhibitor and antiphospholipid antibodies is probably diagnosed to rarely. These two cases emphasize the necessity of meticulous clarification of a prolonged activated partial thromboplastin time (aPTT) and a drop in prothrombin time (PT) during and after ciprofloxacin treatment.

Intracerebral Bleeding and Massive Pericardial Effusion as Presenting Symptoms of Myxedema Crisis

The endocrinological emergency of a fully blown myxedema crisis can present as a multicolored clinical picture. This can obscure the underlying pathology and easily lead to mistakes in clinical diagnosis, work-up, and treatment. We present a case of an unconscious 39-year-old patient with a medical history of weakness, lethargy, and findings of hyponatremia, intracerebral bleeding, and massive pericardial effusion. Finally, myxedema crisis was diagnosed as underlying cause. Replacement therapy of thyroid hormone and conservative management of the intracerebral bleeding resulted in patient's survival without significant neurological impairment. However, diagnostic pericardiocentesis resulted in life-threatening pericardial tamponade. It is of tremendous importance to diagnose myxoedema crisis early to avoid adverse health outcomes.

Evidence indicates that aspirin is effective for the primary prevention of cardiovascular disease (CVD) and colorectal cancer (CRC) but also increases the risk for gastrointestinal (GI) and cerebral hemorrhages. To assess the net balance of benefits and harms from routine aspirin use across clinically relevant age, sex, and CVD risk groups. Decision analysis using a microsimulation model. 3 systematic evidence reviews. Men and women aged 40 to 79 years with a 10-year CVD risk of 20% or less, and no history of CVD and without elevated risk for GI or cerebral hemorrhages that would contraindicate aspirin use. Lifetime, 20 years, and 10 years. Clinical. Low-dose aspirin (≤100 mg/d). Primary outcomes are length and quality of life measured in net life-years and quality-adjusted life-years. Benefits include reduced nonfatal myocardial infarction, nonfatal ischemic stroke, fatal CVD, CRC incidence, and CRC mortality. Harms include increased fatal and nonfatal GI bleeding and hemorrhagic stroke. Lifetime net quality-adjusted life-years are positive for most adults initiating aspirin at ages 40 to 69 years, and life expectancy gains are expected for most men and women initiating aspirin at ages 40 to 59 years and 60 to 69 years with higher CVD risk. Harms may exceed benefits for persons starting aspirin in their 70s and for many during the first 10 to 20 years of use. Results are most sensitive to the relative risk for hemorrhagic stroke and CVD mortality but are affected by all relative risk estimates, baseline GI bleeding incidence and case-fatality rates, and disutilities associated with aspirin use. Aspirin effects by age are uncertain. Stroke benefits are conservatively estimated. Gastrointestinal bleeding incidence and case-fatality rates account only for age and sex. Lifetime aspirin use for primary prevention initiated at younger ages (40 to 69 years) and in persons with higher CVD risk shows the greatest potential for positive net benefit.

Role of transcatheter arterial embolization for massive bleeding from gastroduodenal ulcers

PubMed Central

Loffroy, Romaric; Guiu, Boris

2009-01-01

Intractable bleeding from gastric and duodenal ulcers is associated with significant morbidity and mortality. Aggressive treatment with early endoscopic hemostasis is essential for a favourable outcome. In as many as 12%-17% of patients, endoscopy is either not available or unsuccessful. Endovascular therapy with selective catheterization of the culprit vessel and injection of embolic material has emerged as an alternative to emergent operative intervention in high-risk patients. There has not been a systematic literature review to assess the role for embolotherapy in the treatment of acute upper gastrointestinal bleeding from gastroduodenal ulcers after failed endoscopic hemostasis. Here, we present an overview of indications, techniques, and clinical outcomes after endovascular embolization of acute peptic-ulcer bleeding. Topics of particular relevance to technical and clinical success are also discussed. Our review shows that transcatheter arterial embolization is a safe alternative to surgery for massive gastroduodenal bleeding that is refractory to endoscopic treatment, can be performed with high technical and clinical success rates, and should be considered the salvage treatment of choice in patients at high surgical risk.

A 68-year-old man presented to the emergency department with haematemesis and shock. Upper endoscopy and selective angiography could not identify the source of bleeding. He underwent selective embolisation of the gastroduodenal artery. The patient then had a period of about 24 hours with relative haemodynamic stability before having another episode of massive upper gastrointestinal bleed. A second attempt to embolise the common hepatic artery and distal coeliac axis was unsuccessful. Hence, he was urgently taken to the operating room for exploratory laparotomy. The source of bleeding could not be identified in the operating room. The patient went into cardiac arrest and expired. Autopsy revealed a fistula between proximal jejunum and a previously unknown abdominal aortic aneurysm (AAA). We present an entity that has only been described a few times in the literature while highlighting the importance of having a broad differential with upper gastrointestinal bleeding, especially when the source is not clearly evident. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

Validating the use of rectus muscle fragment welding to control presacral bleeding during rectal mobilization.

PubMed

Ayuste, Edwardo; Roxas, Manuel Francisco T

2004-01-01

The incidence of presacral bleeding during rectal mobilization is low, but such bleeding may be massive and even fatal. Haemostasis can be difficult to achieve using conventional methods because of the complex interlacing of the venous network at the sacral periosteum. Historically, pelvic packing and metallic thumbtacks have been the more commonly used methods in our institution. However, the need for repeat surgery to remove the packs and the difficulties encountered in tack application have forced us to explore other methods. In 1994, the procedure termed muscle fragment welding, which uses electrocautery through a rectum muscle fragment, was introduced to control presacral bleeding. From January 1999 to February 2002, six of 416 patients undergoing pelvic surgery in our institution developed massive presacral haemorrhage and therefore, this technique was used. Haemostasis was immediate and permanent. No major untoward postoperative events such as re-bleeding or infection were noted. One cas developed a second-degree burn in the right elbow due to a misplaced ground conduction plate. Rectus muscle fragment welding is , in our experience, an effective and practical method of controlling presacral haemorrhage.

Upper gastrointestinal bleeding (UGIB) remains a common medical problem worldwide that has significant associated morbidity, mortality, and health care resource use. This study outlines the aetiology, clinical presentation, and treatment outcomes of patients with UGIB in a Nigerian low resource health facility. This was a descriptive study of consecutive patients who underwent upper gastrointestinal (GI) endoscopy for upper GI bleeding in the endoscopy unit of the Obafemi Awolowo University Teaching Hospital Complex, Ile-Ife, Osun State, Nigeria from January 2007 to December 2013. During the study period, 287 (12.4%) of 2,320 patients who underwent upper GI endoscopies had UGIB. Of these, 206 (72.0%) patients were males and their ages ranged from 3 to 100 years with a median age of 49 years. The main clinical presentation included passage of melaena stool in 268 (93.4%) of individuals, 173 (60.3%) had haematemesis, 110 (38.3%) had haematochezia, and 161 (56.1%) were dizzy at presentation. Observed in 88 (30.6%) of UGIB patients, duodenal ulcer was the most common cause, followed by varices [52 (18.1%)] and gastritis [51 (17.1%)]. For variceal bleeding, 15 (28.8%) and 21 (40.4%) of patients had injection sclerotherapy and variceal band ligation, respectively. The overall rebleeding rate for endoscopic therapy for varices was 16.7%. For patients with ulcers, only 42 of 55 who had Forrest grade Ia to IIb ulcers were offered endoscopic therapy. Endoscopic therapy was áin 90.5% of the cases. No rebleeding followed endoscopic therapy for the ulcers. The obtained Rockall scores ranged from 2 to 10 and the median was 5.0. Of all patients, 92.7% had medium or high risk scores. An increase in Rockall score was significantly associated with length of hospital stay and mortality (p < 0.001). The overall mortality rate was 5.9% (17 patients). Endoscopic therapy for UGIB in a resource-poor setting such as Nigeria is feasible, significantly reduces morbidity and mortality, and is cost effective. Efforts should be made to improve the accessibility of these therapeutic procedure for patients with UGIB in Nigeria.

A gastrosplenic fistula (GSF) is a very rare complication that arises mainly from a splenic or gastric large cell lymphoma. The proximity of the gastric fundus to the enlarged fragile spleen may facilitate the fistulisation. This complication can lead to massive bleeding, which, though uncommon, may be lethal. We present a patient with massive upper gastrointestinal bleeding secondary to a GSF. We present a 48-year-old man with a refractory diffuse large B-cell lymphoma who was admitted to our hospital due to hematemesis. On arrival, he was in hemorrhagic shock, and was taken directly to the intensive care unit. The source of bleeding could not be identified on gastroscopy, the patient remained hemodynamically unstable and a laparotomy was performed.A fistula between a branch of the splenic artery and the stomach was identified. The stomach appeared to be involved in the malignant process. After subtotal gastrectomy and splenectomy, the bleeding was controlled. After stabilization, the patient was admitted to the intensive care unit, and 24 hours later was discharged in stable condition. We describe a fistula between a branch of the splenic artery and the stomach, which was accompanied by massive bleeding. An emergency laparotomy saved the patient's life. The purpose of this report is to alert physicians that surgical intervention can be lifesaving in this rare malignant condition. A literature review focusing on the presenting symptoms and the epidemiology of GSF is presented.

Purpose: To identify the dosimetric parameters associated with gastrointestinal (GI) toxicity in patients with locally advanced pancreatic cancer (LAPC) treated with gemcitabine-based chemoradiotherapy. Methods and Materials: The data from 40 patients were analyzed retrospectively. Chemoradiotherapy consisted of conventional fractionated three-dimensional radiotherapy and weekly gemcitabine. Treatment-related acute GI toxicity and upper GI bleeding (UGB) were graded according to the Common Toxicity Criteria Adverse Events, version 4.0. The dosimetric parameters (mean dose, maximal absolute dose which covers 2 cm{sup 3} of the organ, and absolute volume receiving 10-50 Gy [V{sub 10-50}]) of the stomach, duodenum, small intestine, and a composite structure ofmore » the stomach and duodenum (StoDuo) were obtained. The planning target volume was also obtained. Univariate analyses were performed to identify the predictive factors for the risk of grade 2 or greater acute GI toxicity and grade 3 or greater UGB, respectively. Results: The median follow-up period was 15.7 months (range, 4-37). The actual incidence of acute GI toxicity was 33%. The estimated incidence of UGB at 1 year was 20%. Regarding acute GI toxicity, a V{sub 50} of {>=}16 cm{sup 3} of the stomach was the best predictor, and the actual incidence in patients with V{sub 50} <16 cm{sup 3} of the stomach vs. those with V{sub 50} of {>=}16 cm{sup 3} was 9% vs. 61%, respectively (p = 0.001). Regarding UGB, V{sub 50} of {>=}33 cm{sup 3} of the StoDuo was the best predictor, and the estimated incidence at 1 year in patients with V{sub 50} <33 cm{sup 3} of the StoDuo vs. those with V{sub 50} {>=}33 cm{sup 3} was 0% vs. 44%, respectively (p = 0.002). The dosimetric parameters correlated highly with one another. Conclusion: The irradiated absolute volume of the stomach and duodenum are important for the risk of acute GI toxicity and UGB. These results could be helpful in escalating the radiation doses using novel techniques, such as intensity-modulated radiotherapy, for the treatment of pancreatic cancer.« less

We present the case of a 63-year-old man that was admitted for melena and severe anemia. Upper GI endoscopy and colonoscopy failed to identify the lesion responsible for bleeding, and enteroCT scan was also non-contributive to the diagnosis. Capsule endoscopy indicated possible jejunal bleeding but could not indicate the source of bleeding, recommending anterograde enteroscopy. Single balloon enteroscopy identified a 2 cm submucosal tumour in the distal part of the jejunum, with a macroscopic appearance suggesting a gastrointestinal stromal tumour (GIST). The tumor location was marked using SPOT tattoo and subsequently easily identified by the surgeon and resected via minimally invasive laparoscopic-assisted approach. Histological and immunohistochemical analysis indicated a low risk GIST. The unusual small size of the GIST as a modality of presentation, with digestive bleeding and anemia and the ability to use VCE/enteroscopy to identify and mark the lesion prior to minimally invasive surgery, represent the particularities of the presented case.

The aim of this study was to demonstrate epidemiological, clinical and endoscopic characteristics of acute upper gastrointestinal bleeding (UGIB) with special reference to peptic ulcer bleeding (PUB). The study included 2198 consecutive patients referred to our emergency department due to acute UGIB from January 2008 to December 2012. All patients underwent urgent upper GI endoscopy within 24 hours of admission, and 842 patients diagnosed with PUB were enrolled and prospectively followed-up. The cumulative incidence of UGIB was 126/100,000 in the 5-year period. Two out of five patients had a bleeding peptic ulcer; in total, 440 (52.3%) had bleeding gastric ulcer, 356 (42.3%) had bleeding duodenal ulcer, 17 (2%) had both bleeding gastric and duodenal ulcers, and 29 (3.5%) patients had bleeding ulcers on gastroenteric anastomoses. PUB was more common in men. The mean patient age was 65.9 years. The majority of patients (57%) with PUB were taking agents that attenuate the cytoprotective function of gastric and duodenal mucosa. Rebleeding occurred in 77 (9.7%) patients and 47 (5.9%) patients required surgical intervention. The 30-day morality was 5.2% and 10% of patients died from uncontrolled bleeding and concomitant diseases. In conclusion, PUB is the main cause of UGIB, characterized by a significant rebleeding rate and mortality.

To demonstrate the relationship between the timing of opening of the uterine isthmus and bleeding during pregnancy and caesarean section in patients with placenta previa. A prospective observational study was conducted at a single perinatal centre. All patients with placenta previa, diagnosed between 20 and 22 weeks of gestation, who were followed up at the study hospital and underwent caesarean section were enrolled. The condition of the uterine isthmus was examined every 2 weeks. The timing (in gestational weeks) of complete opening of the uterine isthmus was determined. Patients were divided into two groups: patients in whom the uterine isthmus opened before 25 weeks of gestation (EO-previa), and patients in whom the uterine isthmus opened after 25 weeks of gestation (LO-previa). The frequency of bleeding during pregnancy and the amount of intra-operative bleeding were compared between the two groups. Forty-four cases of EO-previa and 55 cases of LO-previa were analysed. Complete placenta previa at delivery was observed more frequently in the EO-previa group than in the LO-previa group (88.6% vs 47.3%, p<0.001). An emergency caesarean section due to active bleeding was performed more frequently in the EO-previa group (48%) than in the LO-previa group (25%) (p=0.021). The frequency of massive haemorrage (>2500ml) during caesarean section was higher in the EO-previa group than in the LO-previa group (25% vs 9%, p=0.033). Placenta previa was associated with a high risk of bleeding leading to emergency caesarean section during pregnancy, and massive haemorrhage during caesarean section in patients in whom the uterine isthmus opened before 25 weeks of gestation.

Currant jelly stool is a late manifestation of intussusception and is rarely seen in clinical practice. Other forms of GI bleeding have not been thoroughly studied and little is known about their respective diagnostic values. To assess the predictive value of GI bleeding (positive guaiac test, bloody stool and rectal bleeding in evaluation of intussusception. We performed a retrospective cross-sectional study cohort of all children, ages 1month-6years of age, who had an abdominal ultrasound obtained evaluating for intussusception over 5year period. We identified intussusception if diagnosed by ultrasound, air-contrast enema or surgery. Univariate and a multivariate logistic regression analysis were performed. During the study period 1258 cases met the study criteria; median age was 1.7years (IQR 0.8, 2.9) and 37% were females. Overall 176 children had intussusception; 153 (87%) were ileo-colic and 23 were ileo-ileal. Univariate risk ratio and adjusted Odds ratio were 1.3 (95% CI, 0.8, 2.0) and 1.3 (0.7, 2.4) for positive guaiac test, 1.1 (0.6, 2.1) and 0.9 (0.3, 3.0) for bloody stool, and 1.7 (1.02, 2.8) and 1.3 (0.5, 3.1) for rectal bleeding . Blood in stool, whether visible or tested by guaiac test has poor diagnostic performance in the evaluation of intussusception and is not independently predictive of intussusception. If the sole purpose of a rectal exam in these patients is for guaiac testing it should be reconsidered. Copyright © 2017 Elsevier Inc. All rights reserved.

Getting to the heart of rectal bleeding: subacute bacterial endocarditis presenting as anaemia and a GI bleed

2011-01-01

In this case report, the authors demonstrate a case of subacute bacterial endocarditis presenting with anaemia. It is the first of its kind to describe a delay in diagnosis due to an initial patient investigation for a bleed rather than a cardiac evaluation. Astute clinicians need to be aware of the causes of anaemia in patients with endocarditis and consider that in Streptococcus bovis (S bovis) infection can be related to gastrointestinal polyps or malignancy resulting in bleeding. Although patients with S bovis endocarditis should undergo full gastrointestinal investigation after endocarditis is diagnosed, it should not delay medical treatment. In this article, the authors discuss the consequences of failing to achieve timely recognition of endocarditis along with common systemic complications. The authors also outline current recommendations for surgical intervention as heart valve replacement surgery was warranted in the patient to prevent fatal outcome. PMID:22674949

Recurrent massive hemorrhage from the ileum as a late complication of radiotherapy has not previously been documented. We describe two patients with a history of pelvic radiotherapy 18 months and 11 yr before, in whom the source of melena was localized to the small bowel preoperatively. Characteristic serosal appearances of ileal radiation injury were present at laparotomy and resection of the terminal ileum controlled the hemorrhage. Pathological study revealed no ulceration but multiple telangiectatic vessels in the tips of mucosal villi. This cause should be considered in patients with obscure gastrointestinal bleeding previously exposed to pelvic radiotherapy.

Abstract Background Ramucirumab, the human immunoglobulin G1 monoclonal antibody receptor antagonist of vascular endothelial growth factor receptor 2, has been approved for treating gastric/gastroesophageal junction, non-small-cell lung, and metastatic colorectal cancers. With the completion of six global, randomized, double-blind, placebo-controlled, phase III trials across multiple tumor types, an opportunity now exists to further establish the safety parameters of ramucirumab across a large patient population. Materials and methods An individual patient meta-analysis across the six completed phase III trials was conducted and the relative risk (RR) and associated 95% confidence intervals (CIs) were derived using fixed-effects or mixed-effects models for all-grade and high-grade adverse events (AEs) possibly related to vascular endothelial growth factor pathway inhibition. The number needed to harm was also calculable due to the placebo-controlled nature of all six registration standard trials. Results A total of 4996 treated patients (N = 2748 in the ramucirumab arm and N = 2248 in the control, placebo arm) were included in this meta-analysis. Arterial thromboembolic events [ATE; all-grade, RR: 0.8, 95% CI 0.5–1.3; high-grade (grade ≥3), RR: 0.9, 95% CI 0.5–1.7], venous thromboembolic events (VTE; all-grade, RR: 0.7, 95% CI 0.5–1.1; high-grade, RR: 0.7, 95% CI 0.4–1.2), high-grade bleeding (RR: 1.1, 95% CI 0.8–1.5), and high-grade gastrointestinal (GI) bleeding (RR: 1.1, 95% CI 0.7–1.7) did not demonstrate a definite increased risk with ramucirumab. A higher percentage of hypertension, proteinuria, low-grade (grade 1–2) bleeding, GI perforation, infusion-related reaction, and wound-healing complications were observed in the ramucirumab arm compared with the control arm. Conclusions Ramucirumab may be distinct among antiangiogenic agents in terms of ATE, VTE, high-grade bleeding, or high-grade GI bleeding by showing no clear evidence for an increased risk of these AEs in this meta-analysis of a large and diverse patient population. Ramucirumab is consistent with other angiogenic inhibitors in the risk of developing certain AEs.

This clinical study compared the effects of an antibacterial regimen, comprising a triclosan toothpaste and a 0.075% cetylpyridinium chloride (CPC) mouthrinse, on malodor, self-reported malodor, and oral hygiene measures such as dental plaque, gingivitis, and bleeding relative to brushing with a fluoride toothpaste. At baseline, 36 subjects were evaluated for malodor (9-point organoleptic scale [OLT]), dental plaque (Turesky modification of Quigley-Hein; PI), gingivitis (Lφe-Silness; GI) and bleeding (Ainamo and Bay; BI) and randomized to (1) tooth brushing with fluoride toothpaste, or (2) a regimen comprising tooth brushing with a triclosan toothpaste and mouth rinsing with CPC mouthrinse. After the first use of assigned treatments, subjects were evaluated for malodor 2 h after breakfast (OLT-2 h) and used provided treatments for the next 14 days. On the 7 th and 14 th days, subjects refrained from oral hygiene for 12 h before evaluations (OLT, PI, GI, and BI) and then performed oral hygiene at the dental clinic. Subjects were evaluated for malodor 2 h after breakfast (OLT-2 h) and self-assessed their malodor on a 100 mm visual analog scale (VAS). Treatment groups demonstrated no significant differences in OLT, PI, GI, BI at baseline (P > 0.05). OLT-2 h scores after the first use of regimen and after tooth brushing alone were 5.94 and 6.21, respectively, and were statistically significantly different (P < 0.05). Correspondingly, the regimen demonstrated progressive reductions in OLT and OLT-2 h on the 7 th and 14 th day evaluations (5.81, 4.88, and 5.09, 4.20, respectively) and were significantly lower than after tooth brushing alone (6.49, 6.18, and 6.35, 5.99, respectively) (P < 0.05). From the 7 th to 14 th days, the regimen also demonstrated progressively lower PI, GI, BI, and self-reported malodor (VAS scores) which were significantly lower than tooth brushing alone (P < 0.05). Results from this study demonstrated that a regimen comprising a triclosan toothpaste and CPC mouthrinse demonstrated significant malodor reductions 2 h after the first use and progressively increasing reductions in malodor, dental plaque, gingivitis, bleeding and self-reported malodor from the 7 th to 14 th days than tooth brushing alone.

The treatment of a bleeding chronic posterior duodenal ulcer, with bleeding recurrence or persistence despite endoscopic therapy, requires surgical treatment and constitutes a challenge for the surgeon; furthermore such chronic ulcers are often wide and sclerotic, so the surgeon needs to avoid the risk of recurrent bleeding if conservative surgery is applied. If radical surgery must be performed, the greater risk involves duodenal leakage, hepatic hilar injury, or pancreatic injury. This study aimed to evaluate the efficacy and complications arising from a surgical procedure, described by Dubois in 1971 (Gastrectomy and gastroduodenal anastomosis for post-bulbar ulcers and peptic ulcers of the second part of the duodenum. J Chir 101:177-186). This operation involves antroduonectomy with gastroduodenal anastomosis. It is similar to a Billroth I gastrectomy but without dissection of the ulcer. We retrospectively studied the medical data of patients who underwent this procedure for the treatment of bleeding chronic posterior duodenal ulcers during the past 20 years. There were 28 such patients admitted to our institution for emergency surgery, who went on to be treated by the Dubois procedure. Ulcerous disease was efficiently treated without rebleeding or duodenal leakage. The mortality rate was 17%; most deaths resulted from medical failure in older patients suffering from massive bleeding. The rate of medical complications reached 21%. Surgical complications developed in 14% of patients. The Dubois antroduodenectomy is a safe and effective surgical procedure for the treatment of bleeding chronic duodenal ulcers. The number of fatal outcomes among patients with this condition remains high, particularly in older and vulnerable patients experiencing massive bleeding.

Nonsteroidal anti-inflammatory drugs (NSAIDs) are one of the most widely consumed pharmaceuticals, yet both the mechanisms involved in their therapeutic actions and side-effects, notably gastrointestinal (GI) ulceration/bleeding, have not been clearly defined. In this study, we have used a number of biochemical, structural, computational and biological systems including; Fourier Transform InfraRed (FTIR). Nuclear Magnetic Resonance (NMR) and Surface Plasmon Resonance (SPR) spectroscopy, and cell culture using a specific fluorescent membrane probe, to demonstrate that NSAIDs have a strong affinity to form ionic and hydrophobic associations with zwitterionic phospholipids, and specifically phosphatidylcholine (PC), that are reversible and non-covalent in nature. We propose that the pH-dependent partition of these potent anti-inflammatory drugs into the phospholipid bilayer, and possibly extracellular mono/multilayers present on the luminal interface of the mucus gel layer, may result in profound changes in the hydrophobicity, fluidity, permeability, biomechanical properties and stability of these membranes and barriers. These changes may not only provide an explanation of how NSAIDs induce surface injury to the GI mucosa as a component in the pathogenic mechanism leading to peptic ulceration and bleeding, but potentially an explanation for a number of (COX-independent) biological actions of this family of pharmaceuticals. This insight also has proven useful in the design and development of a novel class of PC-associated NSAIDs that have reduced GI toxicity while maintaining their essential therapeutic efficacy to inhibit pain and inflammation.

Small bowel enteroscopy and intraoperative enteroscopy for obscure gastrointestinal bleeding.

PubMed

Lewis, B S; Wenger, J S; Waye, J D

1991-02-01

Intraoperative endoscopy (IOE) is accepted as the ultimate diagnostic procedure for completely evaluating the small bowel in patients with obscure gastrointestinal (GI) bleeding. Small bowel enteroscopy (SBE) has been reported useful in the nonsurgical evaluation of the small intestine in these patients, but findings may be limited because of incomplete small bowel intubation and a lack of tip deflection. Twenty-three patients underwent 25 SBE exams and subsequently had 25 IOE exams during surgical exploration for continued bleeding. Patients' bleeding histories averaged 2 yr, with an average transfusion requirement of 27 units. Findings on IOE were the same as with SBE in 17/22 (77%) of examinations. We conclude that SBE and IOE are comparable in depth of insertion and ability to detect small vascular ectasias. Both procedures missed pathology due to limited visibility and the evanescent nature of ectasias. Long-term success in abolishing bleeding with these combined techniques can be expected in 55% of these patients. SBE should precede surgery, since the finding of diffuse ectasias precludes any benefit from operative intervention.

To compare outcomes using the novel portable endoscopy with that of nasogastric (NG) aspiration in patients with gastrointestinal bleeding. Patients who underwent NG aspiration for the evaluation of upper gastrointestinal (UGI) bleeding were eligible for the study. After NG aspiration, we performed the portable endoscopy to identify bleeding evidence in the UGI tract. Then, all patients underwent conventional esophagogastroduodenoscopy as the gold-standard test. The sensitivity, specificity, and accuracy of the portable endoscopy for confirming UGI bleeding were compared with those of NG aspiration. In total, 129 patients who had GI bleeding signs or symptoms were included in the study (age 64.46 ± 13.79, 91 males). The UGI tract (esophagus, stomach, and duodenum) was the most common site of bleeding (81, 62.8%) and the cause of bleeding was not identified in 12 patients (9.3%). Specificity for identifying UGI bleeding was higher with the portable endoscopy than NG aspiration (85.4% vs 68.8%, P = 0.008) while accuracy was comparable. The accuracy of the portable endoscopy was significantly higher than that of NG in the subgroup analysis of patients with esophageal bleeding (88.2% vs 75%, P = 0.004). Food material could be detected more readily by the portable endoscopy than NG tube aspiration (20.9% vs 9.3%, P = 0.014). No serious adverse effect was observed during the portable endoscopy. The portable endoscopy was not superior to NG aspiration for confirming UGI bleeding site. However, this novel portable endoscopy device might provide a benefit over NG aspiration in patients with esophageal bleeding.

Type IV Ehlers-Danlos Syndrome: A Surgical Emergency? A Case of Massive Retroperitoneal Hemorrhage

Retroperitoneal hemorrhagic bleeding is a known manifestation of Type-IV Ehlers-Danlos Syndrome that is caused by loss-of-function mutations of the pro-alpha-1 chains of type III pro-collagen (COL3A1) resulting in vascular fragility. A number of previous reports describe futile surgical intervention for retroperitoneal bleeding in Type-IV Ehlers-Danlos Syndrome with high post-operative mortality, although the rarity of retroperitoneal bleeding associated with Type-IV Ehlers-Danlos Syndrome precludes an evidence-based approach to clinical management. We report a 23-year-old male with history of Type-IV Ehlers-Danlos Syndrome who presented with severe abdominal pain and tachycardia following an episode of vomiting. Further work-up of his abdominal pain revealed massive retroperitoneal bleeding by CT-scan of the abdomen. Given numerous cases of catastrophic injury caused by surgical intervention in Type-IV Ehlers-Danlos Syndrome, the patient was treated non-operatively, and the patient made a full recovery. This case suggests that even in cases of large retroperitoneal hemorrhages associated with Ehlers-Danlos Syndrome, it may not truly represent a surgical emergency. PMID:21966332

Bleeding from anus is usually referred as rectal bleeding but actually rectal bleeding is defined as bleeding from lower colon or rectum, which means bleeding from a place distal to ligament of Treitz. This study was conducted to determine the frequency of different causes of rectal bleeding in patients at Ayub Teaching Hospital, Abbottabad. One hundred and seventy-five patients with evidence of rectal bleed, without gender discrimination were selected by non-probability convenient sampling from the out-patient department and general medical wards. Patients with suspected upper GI source of bleeding; acute infectious bloody diarrhoea and any coagulopathy were excluded from the study. All patients were subjected to fibre optic colonoscopy after preparation of the gut and findings were recorded. Where necessary, biopsy samples were also taken. Diagnosis was based on colonoscopic findings. A total of 175 patients (92 males and 83 females) with mean age 35.81±9.18 years were part of the study. Colonoscopy showed abnormal findings in 150 (85.7%) patients. The commonest diagnosis was haemorrhoids, which was found in 39 (22.3%) patients. It was followed by inflammatory bowel disease (IBD) in 30 (17.1%) patients, solitary rectal ulcer in 13 (7.4%) patients and polyps in 25 (14.3%) patients. Other less frequent findings were non-specific inflammation and fungating growths in rectum. Haemorrhoids was the leading cause of bleeding per rectum in this study, followed by evidence of IBD while infrequent findings of polyps and diverticuli indicate that these are uncommon in this region.

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 rebleeding and 6.90 for need of transfusion after the endoscopy. CONCLUSION: Endoscopist’s experience is an important independent prognostic factor for non-variceal acute upper GI bleeding. Urgent endoscopy should be undertaken preferentially by a skilled endoscopist as less expert staff tends to underestimate some risk lesions with a negative influence on hemostasis. PMID:16437658

To present a case report of a patient with Noonan syndrome who developed life-threatening gastrointestinal bleeding shortly after cardiac surgery that was successfully treated with recombinant factor VIIa. Case report. Pediatric intensive care unit of a children's hospital. Ten-month-old with Noonan syndrome and massive gastrointestinal bleeding resulting in severe hypovolemic shock. Recombinant factor VIIa was used in this patient's severe bleeding associated with Noonan syndrome after no other supportive measures were successful. Recombinant Factor VIIa significantly decreased the patient's bleeding and allowed his hypovolemic shock to improve. Ultimately, the patient made a complete recovery. Noonan syndrome has a constellation of both cardiac and noncardiac malformations including an increased risk of bleeding, and recombinant factor VIIa is an important agent in the treatment of significant bleeding.

The aim of the current study was to assess bleeding events, including severity, localisation and prognostic impact, in a real world population of men and women with myocardial infarction (MI). In total 850 consecutive patients were included during 2010 and followed for one year. Bleeding complications were identified by searching of each patients' medical records and characterised according to the TIMI criteria. For this analysis, only the first event was calculated. The total incidence of bleeding events was 24.4% (81 women and 126 men, p = ns). The incidence of all in-hospital bleeding events was 13.2%, with no sex difference. Women had significantly more minor non-surgery related bleeding events than men (5% vs 2.2%, p = 0.02). During follow-up, 13.5% had a bleeding, with more non-surgery related bleeding events among women, 14.7% vs 9.7% (p = 0.03). The most common bleeding localisation was the gastrointestinal tract, more in women than men (12.1% vs 7.6%, p = 0.03). Women had also more access site bleeding complications (4% vs 1.7%, p = 0.04), while men had more surgery related bleeding complications (6.4% vs 0.9%, p ≤0.001). Increased mortality was found only in men with non-surgery related bleeding events (p = 0.008). Almost one in four patients experienced a bleeding complication through 12 months follow-up after a myocardial infarction. Women experienced more non-surgery related minor/minimal bleeding complications than men, predominantly GI bleeding events and access site bleeding events, with no apparent impact on outcome. In contrast men with non-surgery related bleeding complications had higher mortality. Improved bleeding prevention strategies are warranted for both men and women. Copyright © 2018 Elsevier Ltd.

Acute Upper Gastrointestinal Bleeding is a common medical emergency with a hospital mortality of approximately 10 percent. Higher mortality rate is associated with rebleeding. Rockall scoring system identifies patients at higher risk of rebleed and mortality. To study the clinical and endoscopic profile of acute upper gastrointestinal bleed to know the etiology, clinical presentation, severity of bleeding and outcome. This is a prospective, descriptive hospital based study conducted in Gastroenterology unit of College of Medical Sciences and Teaching Hospital, Bharatpur, Nepal from January 2012 to January 2013. It included 120 patients at random presenting with manifestations of upper gastrointestinal bleed. Their clinical and endoscopic profiles were studied. Rockall scoring system was used to assess their prognosis. Males were predominant (75%). Age ranged from 14 to 88 years, mean being 48.76+17.19. At presentation 86 patients (71.7%) had both hematemesis and malena, 24 patients (20%) had only malena and 10 patients (8.3%) had only hematemesis. Shock was detected in 21.7%, severe anemia and high blood urea were found in 34.2% and 38.3% respectively. Upper Gastrointestinal Bleeding endoscopy revealed esophageal varices (47.5%), peptic ulcer disease (33.3%), erosive mucosal disease (11.6%), Mallory Weiss tear (4.1%) and malignancy (3.3%). Median hospital stay was 7.28+3.18 days. Comorbidities were present in 43.3%. Eighty six patients (71.7%) had Rockall score < 5 and 34 (28.3%) had >6. Five patients (4.2%) expired. Risk factors for death being massive rebleeeding, comorbidities and Rockall score >6. Acute Upper Gastrointestinal bleeding is a medical emergency. Mortality is associated with massive bleeding, comorbidities and Rockall score >6. Urgent, appropriate hospital management definitely helps to reduce morbidity and mortality.

Managing gastrointestinal symptoms after cancer treatment: a practical approach for gastroenterologists

The percentage of the population living with a diagnosis of cancer is rising. By 2030, there will be 4 million cancer survivors in the UK. One quarter of cancer survivors are left with physical symptoms, which affect their quality of life. Gastrointestinal (GI) symptoms are the most common of all chronic physical side-effects of cancer treatment and have the greatest impact on daily activity. Cancer therapies induce long-term changes in bowel function due to alterations to specific GI physiological functions. In addition, the psychological effect of a cancer diagnosis, new GI disease or pre-existing underlying conditions, may also contribute to new symptoms. Twenty-three upper GI symptoms have been identified as occurring after pelvic radiotherapy. After upper GI cancer treatment, the most troublesome symptoms include reflux, abdominal pain, indigestion, diarrhoea and fatigue. Often, several symptoms are present simultaneously and women experience more symptoms than men. The symptoms which patients rate as most difficult are urgency, wind, diarrhoea, incontinence, abdominal pain and rectal bleeding. Recent UK Guidance on managing GI symptoms suggests that these symptoms can be treated especially if gastroenterological advice is combined with dietetic and nursing input to optimise investigations and management. However, as different pathological processes can result in identical symptoms; a systematic, ‘algorithmic’ approach to assess and treat these symptoms is required. This paper aims to illustrate the value of such an approach to investigate and treat the most common GI symptoms that trouble patients. The algorithm allows clinicians to institute a comprehensive medical management plan. PMID:28839701

A successful treatment of life-threatening bleeding from polycystic kidneys with antifibrinolytic agent tranexamic acid.

We describe a successful treatment of a severe, persistent bleeding from both kidneys in a patient with autosomal dominant polycystic kidney disease (ADPKD) with tranexamic acid (TXA), a potent antifibrinolytic agent. The bleeding could not be controlled by intensive conservative treatment, it became life-threatening and urgent bilateral nephrectomy was intended. Since local and systemic hyperfibrinolysis play a role in bleeding in ADPKD patients, we tried TXA treatment. In fact, the massive bleeding promptly stopped, and haematuria gradually ceased. Removal of both kidneys was prevented. After 5 days both ureters became obstructed by blood clots, but placing J-catheters in each pyelon successfully solved this complication. Our case shows that it is reasonable to try antifibrinolytic treatment with TXA in such devastating uncontrolled bleeding.

The daily removal of supragingival dental plaque is a key factor in the prevention of gingivitis. The aim of the study was to compare the gingival health benefits of a triclosan/copolymer/fluoride toothpaste (Colgate Total, a fluoride toothpaste containing an antiseptic) to a commercially available toothpaste containing 0.243% sodium fluoride in a silica base (Colgate Herbal, a conventional fluoride toothpaste with herbal extracts). A total of 50 patients with gingivitis and at least one sensitive tooth were included. The subjects were randomly stratified into two groups: Colgate Total toothpaste, and Colgate Herbal toothpaste. After a 4-week pre-experimental phase, baseline Plaque Index (Quigley-Hein Index) (PI), Gingival Index (GI), Gingival Bleeding Index (GBI), and Visual Analog Scale (VAS) were assessed. The PI, GI, GBI, and VAS were reexamined at weeks 4, 12, and 24 after the baseline. Fifty subjects complied with the protocol and completed the study. The conventional fluoride toothpaste with herbal extracts group and the fluoride toothpaste containing an antiseptic group exhibited significant reductions in PI, GI, GBI, and VAS over time. The amount of reduction after 6 months of the treatment was higher in the Total group compared to Herbal group (1.82 vs 1.39, P = .015 for PI; 0.67 vs 0.37, P < .005 for GI; and 56.64% vs 34.26%, P < .005 for GBI). No significant difference was seen for VAS. Twice daily brushing with a toothpaste containing 0.3% triclosan and polyvinyl methyl ether and maleic acid copolymer provides a more effective level of plaque control and gingival health with no effect on decreasing dentin hypersensitivity compared to conventional fluoride toothpaste. Toothpastes containing triclosan/copolymer, in addition to fluoride, result in a higher reduction in plaque, gingival inflammation, and gingival bleeding when compared with fluoride toothpastes without triclosan/copolymer.

BACKGROUND/OBJECTIVE: Guidelines for the management of patients with nonvariceal upper gastrointestinal bleeding (NVUGIB) are inconsistently applied by health care providers, potentially resulting in suboptimal care and patient outcomes. A needs assessment was performed to assess health care providers’ barriers to the implementation of these guidelines in Canada. METHODS: Semistructured telephone interviews were conducted by trained research personnel with 22 selectively sampled health care professionals actively treating and managing NVUGIB patients, including emergency room physicians (ER), intensivists (ICU), gastroenterologists (GI), gastroenterology nurses and hospital administrators. Participants were chosen from a representative sample of six Canadian community- and academic-based hospitals that participated in a national Canadian audit on the management of NVUGIB. RESULTS: Participants reported substantive gaps in the implementation of NVUGIB guidelines that included the following: lack of knowledge of the specifics of the NVUGIB guidelines (ER, ICU, nurses); limited belief in the value of guidelines, especially in areas where evidence is lacking (ER, ICU); limited belief in the value of available tools to support implementation of guidelines (GI); lack of knowledge of the roles and responsibilities of health care professions and disciplines, and lack of effective collaboration skills (ER, ICU and GI); variability of knowledge and skills of health care professionals within professions (eg, variability of nurses’ knowledge and skills in endoscopic procedures); and perceived overuse of intravenous proton pump inhibitor treatment, with limited concern regarding cost or side effect implications (all participants). CONCLUSIONS: In the present study population, ER, ICU and nurses did not adhere to NVUGIB guidelines because they were neither aware of nor familiar with them, whereas the GI lack of adherence to NVUGIB guidelines was influenced more by attitudinal and contextual barriers. These findings can guide the design of multifaceted educational and behavioural interventions when attempting to effectively disseminate existing guidelines, and for guideline implementation into practice.

Food material could be detected more readily by the portable endoscopy than NG tube aspiration (20.9% vs 9.3%, P = 0.014). No serious adverse effect was observed during the portable endoscopy. CONCLUSION: The portable endoscopy was not superior to NG aspiration for confirming UGI bleeding site. However, this novel portable endoscopy device might provide a benefit over NG aspiration in patients with esophageal bleeding. PMID:25009396

A 74-year old female was transferred to our institution because of blunt chest trauma. Chest X-ray and computed tomography (CT) revealed right haemothorax and little pericardial effusion. She was taken to the operating theatre for emergent operation because of hypotension and massive bleeding from the right-sided chest tube. Cardiopulmonary resuscitation was started during surgical exploration. There were three 1-cm lacerations actively bleeding from the right atrium and inferior vena cava junction, which were repaired successfully. Furthermore, we identified a 10 cm laceration in the right-side pleuropericardium and a communication existing between the pericardial space and the right pleural space. PMID:24218497

Objective To evaluate the safety and efficacy of prophylactic uterine artery embolization (UAE) before obstetrical procedures with high risk for massive bleeding. Materials and Methods A retrospective review of 29 female patients who underwent prophylactic UAE from June 2009 to February 2014 was performed. Indications for prophylactic UAE were as follows: dilatation and curettage (D&C) associated with ectopic pregnancy (cesarean scar pregnancy, n = 9; cervical pregnancy, n = 6), termination of pregnancy with abnormal placentation (placenta previa, n = 8), D&C for retained placenta with vascularity (n = 5), and D&C for suspected gestational trophoblastic disease (n = 1). Their medical records were reviewed to evaluate the safety and efficacy of UAE. Results All women received successful bilateral prophylactic UAE followed by D&C with preservation of the uterus. In all patients, UAE followed by obstetrical procedure prevented significant vaginal bleeding on gynecologic examination. There was no major complication related to UAE. Vaginal spotting continued for 3 months in three cases. Although oligomenorrhea continued for six months in one patient, normal menstruation resumed in all patients afterwards. During follow-up, four had subsequent successful natural pregnancies. Spontaneous abortion occurred in one of them during the first trimester. Conclusion Prophylactic UAE before an obstetrical procedure in patients with high risk of bleeding or symptomatic bleeding may be a safe and effective way to manage or prevent serious bleeding, especially for women who wish to preserve their fertility.

Nonsteroidal anti-inflammatory drugs (NSAIDs) are one of the most widely consumed pharmaceuticals, yet both the mechanisms involved in their therapeutic actions and side-effects, notably gastrointestinal (GI) ulceration/bleeding, have not been clearly defined. In this study, we have used a number of biochemical, structural, computational and biological systems including; Fourier Transform InfraRed (FTIR). Nuclear Magnetic Resonance (NMR) and Surface Plasmon Resonance (SPR) spectroscopy, and cell culture using a specific fluorescent membrane probe, to demonstrate that NSAIDs have a strong affinity to form ionic and hydrophobic associations with zwitterionic phospholipids, and specifically phosphatidylcholine (PC), that are reversible and non-covalent in nature. We propose that the pH-dependent partition of these potent anti-inflammatory drugs into the phospholipid bilayer, and possibly extracellular mono/multilayers present on the luminal interface of the mucus gel layer, may result in profound changes in the hydrophobicity, fluidity, permeability, biomechanical properties and stability of these membranes and barriers. These changes may not only provide an explanation of how NSAIDs induce surface injury to the GI mucosa as a component in the pathogenic mechanism leading to peptic ulceration and bleeding, but potentially an explanation for a number of (COX-independent) biological actions of this family of pharmaceuticals. This insight also has proven useful in the design and development of a novel class of PC-associated NSAIDs that have reduced GI toxicity while maintaining their essential therapeutic efficacy to inhibit pain and inflammation.

To investigate the efficacy of multioverlapping therapy using a polysaccharide nanosheet having 75-nm thickness for sealing and stopping massive venous hemorrhage. The hydrostatic durability of the polysaccharide nanosheet was evaluated in vitro when secured to an incised silicon tube. For in vivo studies, the inferior vena cava (IVC) of rabbits was cut longitudinally, and multiple polysaccharide nanosheets were overlapped onto the injured IVC. The mechanical hydrostatic durability of the nanosheets was gradually augmented by an increasing number of multilayered nanosheets in vitro. This durability was saturated at 80 ± 6 mm Hg by four layers of nanosheets, which was robust enough to seal injured vessel walls of the large IVC. Multioverlapping therapy using nanosheets effectively sealed and stopped bleeding from the injured IVC in vivo. One month later, no inflammatory tissue response was observed around the nanosheet attachment sites of the IVC, while conventional suturing repair in control rabbits showed a severe inflammatory response around the sutured area. The multioverlapping therapy using the polysaccharide nanosheets will effectively stop massive venous bleeding without adverse effects in the immediate or chronic postoperative setting.

2017-02-23

There are currently at least 2 million people in the UK living with and following a cancer diagnosis. Typically four out of every ten people with cancer will receive radiotherapy, but a large proportion of people who have pelvic radiotherapy may go on to develop gastrointestinal (GI) symptoms. This includes rectal bleeding and faecal incontinence, which can have a huge impact on quality of life. These problems often go under-reported by patients and are also under-recognised or under-treated by health professionals. Cancer survivorship is a growing topic that is likely to have a major impact on the NHS, with increasing numbers of patients presenting. A late GI effects of pelvic radiotherapy clinic was set up to address these growing needs of patients with GI symptoms following radiotherapy. This article also shares insights from a doctoral study that is underway looking at people's experiences of living with symptoms following their treatment, in order to improve awareness of the major impact that this can have.

The clinical and endoscopic features of amyloid light-chain (AL) amyloidosis are diverse and mimic various other diseases. Endoscopically, few reports on submucosal hematomas of the gastrointestinal (GI) tract are available in the literature. Here, we report two cases of AL amyloidosis presenting as submucosal hematomas in the absence of clinical disease elsewhere in the body. The 2 cases were referred to our hospital because of hematochezia. The endoscopic findings in both cases were similar in submucosal hematoma formation. However, the clinical courses differed. In the first case, there was no evidence of systemic amyloidosis and the disease was conservatively managed. In the second case, the disease progressed to systemic amyloidosis and the patient died within a short time. We conclude that the endoscopic detection of a submucosal hematoma in the setting of GI bleeding should raise suspicion of AL amyloidosis. Referral to a hematologist should be done immediately for treatment while the involvement is limited to the GI tract. PMID:23125904

Near fatal spontaneous intraperitoneal bleeding: A rare manifestation in a congenital factor X deficiency carrier.

Vinod, K V; Hitha, B; Kaaviya, R; Dutta, T K

2015-03-01

Congenital factor X (FX) deficiency is a rare coagulation disorder of autosomal recessive inheritance, characterized by bleeding of variable severity. Bleeding severity generally correlates with the level of FX functional activity and severe bleeding usually occurs in moderate and severe deficiency, when FX coagulant activity is <5%. FX activity above 10% is infrequently associated with severe bleeding. Here we report the rare occurrence of life-threatening massive spontaneous intraperitoneal bleeding with hypovolemic shock, resulting from spontaneous rupture of an ovarian luteal cyst in a 25-year-old FX deficiency carrier woman, with a FX activity of 26%. She was managed successfully conservatively, with fresh frozen plasma and packed red blood cell transfusions and she showed gradual improvement. The case is being reported to discuss the diagnosis and management of this rare inherited coagulation disorder.

To obtain an overall quantitative estimate of the association between pregnancy and gingival inflammation. Medline and EMBASE databases were searched through August 2011. Prospective cohort or cross-sectional studies assessing the effect of pregnancy on gingival inflammation evaluated by the gingival index (GI) and/or bleeding on probing were included. Meta-analyses were performed if possible. Forty-four articles representing 33 studies (14 cohort and 19 cross-sectional) were included. Meta-analyses, performed whenever possible, revealed (1) a significantly lower GI in pregnant women in the first term compared with those in their second or third term of pregnancy; (2) a lower mean GI score in post-partum women compared with women in their second [WMD = 0.143; 95% CI (0.031; 0.255); p = 0.012] or third term [WMD = 0.256; 95% CI (0.151; 0.360); p < 0.001] of pregnancy, when considering cohort studies; (3) Non-pregnant women had lower mean GI values than women in their second or third term of pregnancy. Small changes in plaque levels were reported. Despite the limited number of studies included in the meta-analyses, the present systematic review confirms the existence of a significant increase in GI throughout pregnancy and between pregnant versus post-partum or non-pregnant women, without a concomitant increase in plaque levels. © 2012 John Wiley & Sons A/S.

To evaluate the impact of rectal balloon (RB) inflation on post-transurethral resection of the prostate (TURP) bleeding in patients with symptomatic benign prostatic hyperplasia. After institutional review board approval, patients who were eligible for TURP were randomized into two equal groups, depending on whether they received postoperative endorectal balloon (RB) (GII) or not (GI). The tip of three-way Foley catheter was fixed to a balloon by a blaster strip to prepare air-tight RB. Postoperatively, the RB was inflated for 15 minutes by a pressure-controlled sphygmomanometer. Perioperative data were compared between both groups, including hemoglobin (Hb) deficit 24-hour postoperatively and at time of discharge. Functional outcomes, anorectal complaints, and adverse events were assessed perioperatively and after 1 and 3 months. Fifty patients were enrolled, including 13 (26%) patients who presented with indwelling urethral catheters. Baseline data and mean resected tissue weight were comparable between both groups, including preoperative Hb (p = 0.17). Immediate postoperative Hb deficit was, comparable between GI and GII patients (0.58 ± 0.18 vs 0.60 ± 0.2, p = 0.56) before RB inflation, respectively. However, compared to GI patients, mean Hb deficit significantly decreased in GII patients 24-hour postoperatively (0.2 ± 0.2 vs 0.7 ± 0.3 g, p = 0.002) and at time of discharge (0.8 ± 0.2 vs 1.3 ± 0.4 g, p = 0.003). GII patients needed significantly less postoperative irrigation (2.1 ± 1.6 vs 8.3 ± 1.8 L, p < 0.001), shorter catheterization time (2.3 ± 0.8 vs 3.8 ± 1.3 days, p < 0.001), and shorter hospital stay (2.6 ± 0.5 vs 4.3 ± 1.0 days, p < 0.001). Both groups were comparable in all functional outcomes at the most recent follow-up. Blood transfusion was needed in only one patient (4%) in GI. No patient needed recystoscopy for hematuria or clot retention in either group, while there were no anorectal complaints reported by GII patients. Post-TURP endorectal balloon inflation seems to be simple, safe, and an efficient procedure to reduce postoperative bleeding and irrigation volume. It is significantly associated with shorter catheterization time and hospital stay.

This study addresses the female player of massively multiplayer online (role-playing) games and investigates how gender identity (GI), indicating a person's identification with characteristics that are traditionally defined as masculine or feminine, can be used to explain playing patterns within the female gender group. Results from an online survey (n=466) show that females' player motivations and play styles vary as a function of their GI, indicating that it is a relevant and additional predictor of play behavior and confirming that female play behavior cannot be generalized based on stereotypical male/female conceptions.

2014-12-01

Blood conservation is a major concern in the management of surgical patients because of transfusion-related complications, limited supply, and health care costs. Tranexamic acid (TXA) and ϵ-aminocaproic acid (ϵACA) are lysine analogue antifibrinolytics used to reduce surgical bleeding and transfusions. To evaluate the efficacy and safety of TXA compared with ϵACA in the management of cardiovascular surgical bleeding at an academic medical center. This single-center, retrospective, observational cohort study included 120 patients undergoing cardiovascular surgery with or without cardiopulmonary bypass, who received at least 1 dose of perioperative TXA or ϵACA. The efficacy outcome-massive perioperative bleeding-was a composite end point of chest tube drainage >1500 mL in any 8-hour period after surgery, perioperative transfusion of 10 or more units of packed red blood cells, reoperation for bleeding, or death from hemorrhage within 30 days. The safety outcomes were incidence of thromboembolic events, postoperative renal dysfunction, seizure, and 30-day all-cause mortality. The primary end point-massive perioperative bleeding-occurred in 10 patients (16.7%) in the TXA group compared with 5 patients (8.3%) in the ϵACA group (P = 0.17). There were no significant differences in the secondary end points of 30-day all-cause mortality, thromboembolic events, renal dysfunction, and seizure. There were no differences in the efficacy and safety outcomes between TXA and ϵACA in the management of cardiovascular surgical bleeding at our institution. Considering the substantial cost difference and comparable efficacy and safety, ϵACA may have better value over TXA for reducing cardiovascular surgical bleeding. © The Author(s) 2014.

An important cause of intestinal bleeding in patients with chronic renal failure is angiodysplasia. In retrospective reports up to 19-32% of patients had bleeding from angiodysplastic lesions. These are usually multiple, have a high tendency of rebleeding (25-47%) and are often located in the stomach and duodenum, but can affect the colon and the jejunum as well. Bleeding from angiodysplastic lesions is usually low grade and stops spontaneously in more than 90% of patients, but some times may be life threatening necessitate therapeutic interventions to achieve hemostasis. We report a case of an 18-year old female with renal failure on CAPD who presented a massive lower gastrointestinal bleeding and imposed emergency surgery.

Significant Traumatic Intracranial Hemorrhage in the Setting of Massive Bee Venom-Induced Coagulopathy: A Case Report.

PubMed

Stack, Kelsey; Pryor, Lindsey

2016-09-01

Bees and wasps of the Hymenoptera order are encountered on a daily basis throughout the world. Some encounters prove harmless, while others can have significant morbidity and mortality. Hymenoptera venom is thought to contain an enzyme that can cleave phospholipids and cause significant coagulation abnormalities. This toxin and others can lead to reactions ranging from local inflammation to anaphylaxis. We report a single case of a previously healthy man who presented to the emergency department with altered mental status and anaphylaxis after a massive honeybee envenomation that caused a fall from standing resulting in significant head injury. He was found to have significant coagulopathy and subdural bleeding that progressed to near brain herniation requiring emergent decompression. Trauma can easily occur to individuals escaping swarms of hymenoptera. Closer attention must be paid to potential bleeding sources in these patients and in patients with massive bee envenomation.

Recently, endoscopic clip application devices have undergone redesign and improvements to optimize their clinical use and effectiveness. Initially designed for the treatment of bleeding nonvariceal lesions, these devices are also increasingly used for the closure of perforations, fistulas, and anastomotic leaks. Several clinical studies, both randomized and nonrandomized, have used endoscopic hemoclips for hemostasis. However, no comparative studies have yet been reported in the literature comparing the latest endoscopic clip devices for usability and effectiveness for hemostasis of acute upper GI hemorrhage. We aimed to compare the usability and efficacy of 3 different types of endoscopic clip application devices in an established experimental setting by using a porcine ex-vivo simulator of upper GI hemorrhage. Randomized, controlled, ex-vivo study. Academic medical center. Spurting vessels were created within ex-vivo porcine stomachs as published in prior studies. The vessels were attached to a pressure transducer to record the pressure of the circulating blood replacement. Before the initiation of bleeding, each vessel was randomized to 1 of 3 endoscopic clipping devices: 2 different commonly used hemoclips deployed through the working channel and 1 novel clip deployed via an over-the-scope applications device. Two investigators treated 45 bleeding sites (15 bleeding sites for each device at various randomized locations in the stomach: fundus, body, and antrum). Usability was measured via the endpoints of procedure time and quantity of clips required to achieve hemostasis. Efficacy was measured via the endpoint of pressure increase (Δp) from baseline to after treatment. All of the 45 hemostasis treatments were carried out successfully. The mean procedure times were significantly different among the hemoclips, with the clip deployed in an over-the-scope fashion requiring significantly less time to attain hemostasis compared with the other 2 clips. For number of clips needed to attain hemostasis, the clip deployed in an over-the-scope fashion was significantly superior to the others. There were also significant differences among the changes in pressure (Δp ± SD) among the different hemoclips tested. Ex-vivo study. In this prospective, randomized ex-vivo study, we observed significant differences in the usability (time to achieve hemostasis and number of clips required) and the efficacy (change in pressure achieved by the hemoclips) among the 3 clips. The clip applied in the over-the-scope fashion was superior to the other 2 tested clips with regard to time to achieve hemostasis and number of clips required.

Abstract Enteromorpha linza, a green alga, has been recognized as a potential source of natural antimicrobial and antifungal compounds. We previously reported that an E. linza extract strongly inhibited the growth of Prevotella intermedia and Porphyromonas gingivalis. The principal objective of this study was to evaluate the clinical effect of a mouth rinse containing the E. linza extract on gingivitis disease, as measured by the plaque index (PI), gingival index (GI), and bleeding on probing (BOP), and on two bacterial strains (P. intermedia and P. gingivalis), in comparison with Listerine® (Listerine-Korea, Seoul, Korea), which was used as a positive control. In total, 55 subjects were recruited into active participation in this clinical study. The PI, GI, BOP, and bacterial strains were then evaluated over a test period of 6 weeks. After 1, 2, 4, and 6 weeks, the same clinical indices were recorded, and the levels of P. intermedia and P. gingivalis were quantified via real-time polymerase chain reaction. At the end of the study, the group using the mouth rinse containing the E. linza extract evidenced significant reductions in the clinical indices (PI, GI, and BOP) and P. gingivalis compared with baseline values. Moreover, E. linza extract containing mouth rinse produced effects similar to those of Listerine. Overall, these results indicate that a mouth rinse containing E. linza extract significantly reduces plaque, improves the condition of gingival tissues, and reduces bleeding. Additionally, E. linza extract mouth rinse significantly inhibits P. gingivalis and P. intermedia. Thus, this clinical study demonstrated that the twice-daily use of an E. linza extract mouth rinse can inhibit and prevent gingivitis. PMID:22145775

Bleeding from gastric varices due to splenic vein obstruction is extremely rare in children, but it can be catastrophic. Reported herein is the case of a teenager with splenic vein thrombosis and chronic decompensated liver disease from autoimmune hepatitis who presented with massive gastric variceal bleeding. Standard medical management did not control the bleeding. Due to decompensated liver disease and continuous active bleeding, emergency partial splenic artery embolization was preferred over splenectomy or a shunt procedure. Bleeding was successfully controlled by partial splenic artery embolization by decreasing the inflow of blood into the portal system. It is concluded that emergency partial splenic artery embolization is a safer alternative life-saving procedure to manage severe gastric variceal bleeding due to splenic vein obstruction in a patient with high surgical risk. To our knowledge, only one other patient with similar management has been reported in the pediatric age group. © 2013 The Authors. Pediatrics International © 2013 Japan Pediatric Society.

A global quantitative survey of hemostatic assessment in postpartum hemorrhage and experience with associated bleeding disorders.

Coagulopathy may be a serious complicating or contributing factor to postpartum hemorrhage (PPH), and should be promptly recognized to ensure proper bleeding management. This study aims to evaluate the approaches of obstetrician-gynecologists worldwide towards assessing massive PPH caused by underlying bleeding disorders. A quantitative survey was completed by 302 obstetrician-gynecologists from 6 countries (the UK, France, Germany, Italy, Spain, and Japan). The survey included questions on the use of hematologic laboratory studies, interpretation of results, laboratory's role in coagulation assessments, and experience with bleeding disorders. Overall, the most common definitions of "massive" PPH were >2,000 mL (39%) and >1,500 mL (34%) blood loss. The most common criteria for rechecking a "stat" complete blood count and for performing coagulation studies were a drop in blood pressure (73%) and ongoing visible bleeding (78%), respectively. Laboratory coagulation (prothrombin time/activated partial thromboplastin time [PT/aPTT]) and factor VIII/IX assays were performed on-site more often than were mixing studies (laboratory coagulation studies, 93%; factor VIII/IX assays, 63%; mixing studies, 22%). Most commonly consulted sources of additional information were colleagues within one's own specialty (68%) and other specialists (67%). Most respondents had consulted with a hematologist (78%; least, Germany [56%]; greatest, UK [98%]). The most common reason for not consulting was hematologist unavailability (44%). The most commonly reported thresholds for concern with PT and aPTT were 13 to 20 seconds (36%) and 30 to 45 seconds (50%), respectively. Most respondents reported having discovered an underlying bleeding disorder (58%; least, Japan [35%]; greatest, Spain [74%]). Global survey results highlight similarities and differences between countries in how PPH is assessed and varying levels of obstetrician-gynecologist experience with identification of underlying bleeding disorders and engagement of hematology consultants. Opportunities to improve patient management of PPH associated with bleeding disorders include greater familiarity with interpreting PT/aPTT test results and identification of and consistent consultation with hematologists with relevant expertise.

Medications as causes of intraluminal hyperdensities: what radiologists need to know.

In computed tomography (CT) angiogram or some dedicated CT studies of the abdomen, the use of positive enteric contrast should be avoided as its presence could decrease the sensitivity of the test. There are, however, cases of CT scans with unexpected hyperdense intraluminal contents detected due to the use of certain oral or rectal medications. Reports on medications as causes of intraluminal hyperdensities are sparse in the English literature. We have studied several commonly used medications and revealed that many drugs appear hyperdense in CT scans. The presence of unexpected intraluminal hyperdensities can potentially cause erroneous interpretation of images and in some cases decrease the sensitivity of the test. The hyperdense bowel contents may be mistaken as acute hemorrhage in CT angiogram for detection of GI bleeding. Active GI bleeding, presented as intraluminal extravasation of contrast material, can also be obscured. Certain intra-abdominal pathologies could be masked, for example, in plain CT scan for detection of urinary tract stones or in contrast CT study for suspected bowel ischaemia. It is important for radiologists and clinicians to be aware of this situation in order to prevent misinterpretation of images and to select the most appropriate imaging modality when such unexpected intraluminal hyperdensities are encountered.

Transfusion of Packed Red Blood Cells--The Indications Have Changed.

PubMed

Cook, Alan; Miller, Nate

2015-12-01

Whole blood/packed red blood cells (pRBC) units transfused in the U.S. totaled 13,785,000 in 2011. A single institution in South Dakota transfused 6,485 units of pRBC in 2013. Current thresholds for transfusion have changed and each transfusion has the risk of causing an adverse reaction; thus, it is important to ensure pRBCs are administered appropriately. Due to these changes and the potential risks associated with transfusion, we reviewed the literature regarding appropriate indications for transfusion of pRBC. Our review specifically focused on four disease entities: iron-deficiency anemia, acute upper gastrointestinal (GI) bleeding, acute coronary syndromes, and chronic ischemic heart disease. Based on our findings, we recommend utilizing an overall conservative approach to the transfusion of pRBC. In patients with iron-deficiency anemia, first try alternative methods to improve hemoglobin levels; in those with acute GI bleeding, transfuse for hemoglobin less than 7 g/dL; in patients with acute coronary syndromes, let symptoms/signs be your guide; and in patients with ischemic heart disease, transfuse for hemoglobin levels less than 8 g/dL or if they are symptomatic. Most importantly, be cautious to not fixate on numbers alone; always incorporate patients' symptoms and co-morbidities when considering whether to transfuse pRBCs.

A Preliminary Observation of Weight Loss Following Left Gastric Artery Embolization in Humans

PubMed Central

Gunn, Andrew J.; Oklu, Rahmi

2014-01-01

Background/Objectives. Embolization of the left gastric artery (LGA), which preferentially supplies the gastric fundus, has been shown to produce weight loss in animal models. However, weight loss after LGA embolization in humans has not been previously established. The aim of this study was to evaluate postprocedural weight loss in patients following LGA embolization. Subjects/Methods. A retrospective analysis of the medical records of patients who underwent LGA embolization for upper gastrointestinal (GI) bleeding was performed. Postprocedural weight loss in this group was compared to a control group of patients who had undergone embolization of other arteries for upper GI bleeding. Results. The experimental group (N = 19) lost an average of 7.3% of their initial body weight within three months of LGA embolization, which was significantly greater than the 2% weight loss observed in the control group (N = 28) (P = 0.006). No significant differences were seen between the groups in preprocedural body mass index (BMI), age, postprocedural care in the intensive care unit, history of malignancy, serum creatinine, or left ventricular ejection fraction. Conclusions. The current data suggest that body weight in humans may be modulated via LGA embolization. Continued research is warranted with prospective studies to further investigate this phenomenon. PMID:25349724

Use of Condom Tamponade to Manage Massive Obstetric Hemorrhage at a Tertiary Center in Rajasthan.

Hasabe, Rakesh; Gupta, Kumud; Rathode, Pallavi

2016-10-01

Conventionally postpartum hemorrhage (PPH) has been defined as blood loss of more than 500 ml following vaginal delivery and 1000 ml following a cesarean section [Pritchard et al. in Am J Obstet Gynecol 84(10):1271-1282, (1962)]. Another definition labels PPH as any blood loss which causes a 10 % drop in hematocrit [Combs et al. in Obstet Gynecol 77:69-76, (1991)] or which threatens the hemodynamic stability of the patient and necessitates blood transfusion [Prendiville et al. in Cochrane Database Syst Rev 2:CD000007, (2000)]. The purpose of this study was to evaluate the effectiveness of condom tamponade in the management of massive obstetric hemorrhage. To evaluate the efficacy of a condom as a tamponade for intrauterine pressure to stop massive PPH. This prospective study was done in the Obstetrics and Gynecology Department of NIMS Medical College and Hospital, Jaipur, between December 2013 and February 2015. With aseptic precautions, a sterile rubber catheter fitted with a condom was introduced into the uterus. The condom was inflated with 250-500 ml normal saline according to need. Vaginal bleeding was observed, and further inflation was stopped when bleeding ceased. In all but 2 (94.44 %) the cases, postpartum bleeding was stopped within 10 min of creation of tamponade. On an average, 350 ml of normal saline was required to create adequate tamponade to stop the bleeding. Use of condom tamponade can effectively help in reducing both maternal morbidity and mortality associated with PPH. Our study encourages use of condom tamponade which is efficient, cost-effective, easily available and requires lesser skills as compared to the traditional surgical procedures.

Duodenal leiomyoma represents a very unusual cause for acute gastrointestinal bleeding. The authors report the case of a 49-year-old male with a massive bleeding from an ulcerated duodenal leiomyoma involving the ampulla of Vater. An emergency Whipple's pancreaticoduodenectomy was carried out under suspicion of local malignancy. It is emphasized that the proper diagnosis of smooth muscle tumors is often difficult, both clinically and from the pathological point of view.

Massive hemothorax in patients on extracorporeal membrane oxygenation (ECMO) is potentially life threatening and remains a medical challenge. In this study, we present the clinical results of using aggressive management to treat a consecutive series of patients on ECMO whose conditions were complicated by massive hemothorax. Between November 2003 and February 2010, 14 adult patients on ECMO developed massive hemothorax that was unrelated to the cannulation problems of the ECMO circuit at National Taiwan University Hospital, Taipei, Taiwan. Information was obtained regarding patient demographics, disease course, and treatment. Aggressive treatment of hemothorax included blood component therapy, chest tube drainage, pleural epinephrine irrigation, and surgical intervention. The criteria for surgical intervention, video-assisted thoracoscopic surgery (VATS), or open-window thoracostomy included one-third or more of the thoracic cavity that had accumulated blood clots resulting in a compromised cardiopulmonary status, continuous blood loss > 300mL/hour for 4 hours or more, or continued bleeding for 24 hours after persistent blood transfusion. All hemothoraces were unilateral. With coagulopathic correction, control of bleeding was obtained in two patients after decompression of the pleural cavity, four patients after pleural epinephrine irrigation, and eight of 14 patients required surgical intervention for blood clot evacuation. There were no specific findings except blood clot accumulation in each of the patients who underwent thoracotomy or VATS. Three of the eight patients required multiple operations to treat persistent bleeding. The in-hospital mortality rate was 36% (5 of 14 patients); one patient died of intractable bleeding and four deaths were related to multiple organ failure. Blood transfusion (Mann-Whitney U test; p=0.039) and comorbidities such as bacteremia, septic shock, diabetic mellitus, and immunocompromised status (Fisher exact test; p=0.031) were found to be significant and independent predictors of mortality. However, other factors such as age, complicated pneumothorax, and ECMO circuit duration were not statistically correlated with mortality. ECMO-related massive hemothorax usually occurred unilaterally and presented as a life-threatening condition. With intensive treatment, nearly two-thirds of the patients were saved. The most significant risk factor for mortality was the presence of a comorbidity such as sepsis, diabetic mellitus, or immunocompromised status. Copyright © 2012. Published by Elsevier B.V.

Recombinant activated factor VII for bleeding in patients without inherited bleeding disorders.

(1) Recombinant activated factor VII (rFVIIa) is licensed in Canada for the prevention and treatment of bleeding in hemophiliacs, but it is increasingly used to control bleeding in non-hemophilic patients during surgery, or during treatment for severe trauma or intracerebral hemorrhage (ICH). (2) In one clinical trial, there was a significant reduction in mortality among patients with ICH treated with rFVIIa. In another trial, administration of rFVIIa significantly reduced the number of trauma patients needing massive blood transfusions although there was no significant difference in mortality. (3) Adequately powered randomized controlled trials are needed to clarify the efficacy and safety of rFVIIa for non-bleeding disorder indications. Phase III trials in ICH and trauma are underway. (4) There is potential for non-hemophilic use, particularly if clinical efficacy and cost effectiveness are established.

Conventional endoscopic resection techniques such as endoscopic mucosal resection (EMR) or endoscopic submucosal dissection (ESD) are powerful tools for the treatment of gastrointestinal (GI) neoplasms. However, those techniques are limited to the superficial layers of the GI wall (mucosa and submucosa). Lesions without lifting sign (usually arising from deeper layers) or lesions in difficult anatomic positions (appendix, diverticulum) are difficult - if not impossible - to resect using conventional techniques, due to the increased risk of complications. For larger lesions (>2 cm), ESD appears to be superior to the conventional techniques because of the en bloc resection, but the procedure is technically challenging, time consuming, and associated with complications even in experienced hands. Since the development of the over-the-scope clips (OTSC), complications like bleeding or perforation can be endoscopically better managed. In recent years, different endoscopic full-thickness resection techniques came to the focus of interventional endoscopy. Since September 2014, the full-thickness resection device (FTRD) has the CE marking in Europe for full-thickness resection in the lower GI tract. Technically the device is based on the OTSC system and combines OTSC application and snare polypectomy in one step. This study shows all full-thickness resection techniques currently available, but clearly focuses on the experience with the FTRD in the lower GI tract.

A Rare Case of Fatal Haemorrhage After Tracheostomy

Praveen, CV; Martin, A

2007-01-01

Tracheo-arterial fistula after tracheostomy causing massive haemorrhage is fortunately rare, but can be serious and often fatal. Brachiocephalic trunk is commonly at risk of erosion because of its close relation with the trachea. Factors responsible for fistula are pressure from tube rubbing on the trachea and adjacent vessel, infection, malignant neoplastic invasion of a vessel near the trachea and low tracheostomy. We present a rare case of massive arterial bleeding which happened on the second day and recurred on fifth day, because of slippage of the ligature from the thyroid artery, causing aspiration and death. A low tracheostomy below the third ring should be avoided. If there is bleeding, as a first-aid measure the cuff should be over inflated without removing the tracheostomy tube. PMID:17999811

Plasma transfusion for patients with severe hemorrhage: what is the evidence?

PubMed

Callum, Jeannie L; Rizoli, Sandro

2012-05-01

The following review will detail the current knowledge in massive hemorrhage with regard to the pathophysiology of the coagulation disturbance, the role of plasma, the role of alternatives to plasma, and the clinical value of having a massive transfusion protocol. The coagulation disturbance in trauma patients is more than just the result of consumption of clotting factors at sites of injury and dilution from the infusion of intravenous fluids and red blood cells (RBCs). Even before substantial amounts of fluid resuscitation and RBC transfusion, one-quarter of trauma patients already have abnormal coagulation variables. There is an apparent role for the activation of protein C, hypofibrinogenemia, and fibrin(gen)olysis in the coagulation disturbance after trauma and massive hemorrhage. None of these three disturbances would be completely mitigated by the use of plasma alone, suggesting that there may be an opportunity to improve care of these patients with alternative strategies, such as fibrinogen concentrates and antifibrinolytics. Despite numerous retrospective cohort studies evaluating 1:1 plasma to RBC formula-driven resuscitation, the overall clinical value of this approach is unclear. Studies have even raised concerns regarding a potential increase in morbidity associated with this approach, particularly for patients overtriaged to 1:1 where a massive transfusion is unlikely. We also do not have sufficient evidence to recommend either goal-directed therapy with thromboelastography or early use of fibrinogen replacement, with either cryoprecipitate or fibrinogen concentrates. We have high-quality data that argue against the role for recombinant Factor VIIa that should prompt removal of this strategy from existing protocols. In contrast, we have high-level evidence that all bleeding trauma patients should receive tranexamic acid as soon as possible after injury. This therapy must be included in hemorrhage protocols. If we are to improve the care of massively bleeding patients on a firm scientific ground, we will need large-scale randomized trials to delineate the role of coagulation replacement and the utility of laboratory monitoring. But even until these trials are completed, it is clear that a massive transfusion protocol is needed in all hospitals that manage bleeding patients, to ensure a prompt and coordinated response to hemorrhage. © 2012 American Association of Blood Banks.

Spontaneous massive haemothorax is rare. We describe a healthy 44 year old woman who experience sudden onset chest pain while sleeping. Chest radiograph revealed massive right pleural effusion. Progressive dyspnoea, cold sweating, and tachycardia developed later. A tube thoracostomy was performed immediately and massive haemothorax was noted. An emergency thoracotomy was performed because of unstable vital signs. Disruption of the right third intercostal vein with continuous bleeding was observed, and suture ligation of the vein was performed. The total blood loss was about 4000 ml. The patient recovered uneventfully, and her condition at follow up visits to the outpatient department was satisfactory. PMID:16921070

Airway stabilization for severe, symptomatic tracheobronchomalacia (TBM) may be accomplished by silicone Y-stent placement. Common complications of the Y-stent include mucus plugging and granulation tissue formation. We describe a rare case of massive hemoptysis originating from a silicone Y-stent placed for TBM. An emergent bronchoscopy showed an actively bleeding, pulsatile vessel at the distal end of the left bronchial limb of the Y-stent. It was felt that the bleeding was caused by, or at least impacted by, the distal left bronchial limb of the Y-stent eroding into the airway wall. We hypothesized that placement of oxidized regenerated cellulose (ORC) would provide initial hemostasis, and the subsequent placement of a biocompatible surgical sealant would lead to definitive resolution. ORC provided sufficient hemostasis and the subsequent synthetic polymer reinforced the tissue for complete cessation of the bleed. The combined use of ORC and a biocompatible surgical sealant provided long-term management for life-threatening hemoptysis, and potentially morbid procedures such as embolization or surgery were avoided by advanced endobronchial therapy.

Bleeding from a pancreatic pseudocyst is a severe complication after pancreatitis that can lead to a massive gastrointestinal blood loss. Pseudocyst rupture into the stomach is an unusual complication. We report the case of a 34-year-old woman with a history of alcoholism and a pancreatic pseudocyst. One year after follow-up of her pseudocyst, she arrived at the emergency room with an episode of upper gastrointestinal bleeding. An upper digestive endoscopy showed active bleeding in the subcardial fundus, which could not be endoscopically controlled. Abdominal angio-CT confirmed the diagnosis of a splenic artery pseudoaneurysm in close contact with the back wall of the stomach, as well as a likely fistulization of it. The patient was urgently operated and a distal splenopancreatectomy and fistulorrhaphy was performed. The rupture of a splenic artery pseudoaneurysm may rarely present as upper gastrointestinal bleeding. This may be lethal if not urgently treated.

Introduction We describe a case of rare complication of typhoid fever in a seven-year-old child and review the literature with regard to other rare causes of bleeding per rectum. Dieulafoy's lesion is an uncommon but important cause of recurrent gastrointestinal bleeding. Dieulafoy's lesion located extragastrically is rare. We report a case of typhoid ulcer with Dieulafoy's lesion of the ileum causing severe life-threatening bleeding and discuss the management of this extremely uncommon entity. Case presentation As a complication of typhoid fever, a seven-year-old Kurdish girl from Northern Iraq developed massive fresh bleeding per rectum. During colonoscopy and laparotomy, she was discovered to have multiple bleeding ulcers within the Dieulafoy's lesion in the terminal ileum and ileocecal region. Conclusion Although there is no practical way of predicting the occurrence of such rare complications, we emphasize in this case report the wide array of pathologies that can result from typhoid fever.

The ability to easily predict the need for massive transfusion may improve the process of care, allowing early mobilization of resources. There are currently no clear criteria to activate massive transfusion in severely injured trauma patients. The aims of this study were to create a scoring system to predict the need for massive transfusion and then to validate this scoring system. We reviewed the records of 119 severely injured trauma patients and identified massive transfusion predictors using statistical methods. Each predictor was converted into a simple score based on the odds ratio in a multivariate logistic regression analysis. The Traumatic Bleeding Severity Score (TBSS) was defined as the sum of the component scores. The predictive value of the TBSS for massive transfusion was then validated, using data from 113 severely injured trauma patients. Receiver operating characteristic curve analysis was performed to compare the results of TBSS with the Trauma-Associated Severe Hemorrhage score and the Assessment of Blood Consumption score. In the development phase, five predictors of massive transfusion were identified, including age, systolic blood pressure, the Focused Assessment with Sonography for Trauma scan, severity of pelvic fracture, and lactate level. The maximum TBSS is 57 points. In the validation study, the average TBSS in patients who received massive transfusion was significantly greater (24.2 [6.7]) than the score of patients who did not (6.2 [4.7]) (p < 0.01). The area under the receiver operating characteristic curve, sensitivity, and specificity for a TBSS greater than 15 points was 0.985 (significantly higher than the other scoring systems evaluated at 0.892 and 0.813, respectively), 97.4%, and 96.2%, respectively. The TBSS is simple to calculate using an available iOS application and is accurate in predicting the need for massive transfusion. Additional multicenter studies are needed to further validate this scoring system and further assess its utility. Prognostic study, level III.

To evaluate the use of routinely collected data to determine the cause(s) of critical bleeding in patients who receive massive transfusion (MT). Routinely collected data are increasingly being used to describe and evaluate transfusion practice. Chart reviews were undertaken on 10 randomly selected MT patients at 48 hospitals across Australia and New Zealand to determine the cause(s) of critical bleeding. Diagnosis-related group (DRG) and International Classification of Diseases (ICD) codes were extracted separately and used to assign each patient a cause of critical bleeding. These were compared against chart review using percentage agreement and kappa statistics. A total of 427 MT patients were included with complete ICD and DRG data for 427 (100%) and 396 (93%), respectively. Good overall agreement was found between chart review and ICD codes (78·3%; κ = 0·74, 95% CI 0·70-0·79) and only fair overall agreement with DRG (51%; κ = 0·45, 95% CI 0·40-0·50). Both ICD and DRG were sensitive and accurate for classifying obstetric haemorrhage patients (98% sensitivity and κ > 0·94). However, compared with the ICD algorithm, DRGs were less sensitive and accurate in classifying bleeding as a result of gastrointestinal haemorrhage (74% vs 8%; κ = 0·75 vs 0·1), trauma (92% vs 62%; κ = 0·78 vs 0·67), cardiac (80% vs 57%; κ = 0·79 vs 0·60) and vascular surgery (64% vs 56%; κ = 0·69 vs 0·65). Algorithms using ICD codes can determine the cause of critical bleeding in patients requiring MT with good to excellent agreement with clinical history. DRG are less suitable to determine critical bleeding causes. © 2016 British Blood Transfusion Society.

Bleeding from ectopic varices, which is rare in patients with portal hypertension, is generally massive and life-threatening. Forty-three patients were hospitalized in our ward for gastrointestinal bleeding from ectopic varices. The frequency of ectopic varices was 43/1218 (3.5%) among portal hypertensive patients in our ward. The locations of the ectopic varices were rectal in thirty-two, duodenal in three, intestinal in two, vesical in three, stomal in one, and colonic in two patients. Endoscopic or interventional radiologic treatment was performed successfully for ectopic varices. Hemorrhage from ectopic varices should be kept in mind in patients with portal hypertension presenting with lower gastrointestinal bleeding. PMID:21994879

Robotic right colectomy for hemorrhagic right colon cancer: a case report and review of the literature of minimally invasive urgent colectomy.

Right colon cancer rarely presents as an emergency, in which bowel occlusion and massive bleeding are the most common clinical presentations. Although there are no definite guidelines, the first line treatment for massive right colon cancer bleeding should ideally stop the bleeding using endoscopy or interventional radiology, subsequently allowing proper tumor staging and planning of a definite treatment strategy. Minimally invasive approaches for right and left colectomy have progressively increased and are widely performed in elective settings, with laparoscopy chosen in the majority of cases. Conversely, in emergent and urgent surgeries, minimally invasive techniques are rarely performed. We report a case of an 86-year-old woman who was successfully treated for massive rectal bleeding in an urgent setting by robotic surgery (da Vinci Intuitive Surgical System®). At admission, the patient had severe anemia (Hb 6 g/dL) and hemodynamic stability. A computer tomography scanner with contrast enhancement showed a right colon cancer with active bleeding; no distant metastases were found. A colonoscopy did not show any other bowel lesion, while a constant bleeding from the right pre-stenotic colon mass was temporarily arrested by endoscopic argon coagulation. A robotic right colectomy in urgent setting (within 24 hours from admission) was indicated. A three-armed robot was used with docking in the right side of the patient and a fourth trocar for the assistant surgeon. Because of the patient's poor nutritional status, a double-barreled ileocolostomy was performed. The post-operative period was uneventful. As the neoplasia was a pT3N0 adenocarcinoma, surveillance was decided after a multidisciplinary meeting, and restoration of the intestinal continuity was performed 3 months later, once good nutritional status was achieved. In addition, we reviewed the current literature on minimally invasive colectomy performed for colon carcinoma in emergent or urgent setting. No study on robotic approach was found. Seven studies evaluating the role of laparoscopic colectomy concluded that this technique is a safe and feasible option associated with lower blood loss and shorter hospital stay. It may require longer operative time, but morbidity and mortality rates appeared comparable to open colectomy. However, the surgeon's experience and the right selection of candidate patients cannot be understated.

Long-term prophylaxis in severe factor VII deficiency.

The spectrum of bleeding problems in FVII deficiency is highly variable and FVII levels and causative genetic mutations correlate poorly with the bleeding risk. Long-term prophylaxis is generally initiated in order to prevent subsequent CNS bleeding after a first event or in patients with other major/ life threatening/ frequent bleeding symptoms as gastrointestinal bleeding or hemarthrosis. However few data are available in the literature regarding FVII prophylaxis and clinical decisions cannot be based on evidence. We report the data available in the literature on FVII prophylaxis and our personal experience regarding three patients affected by severe FVII deficiency. Specific papers on long-term prophylaxis in severe FVII deficiency were identified using the database, PUBMED. The most frequent indications for long-term prophylaxis were CNS bleeding (58%), hemartrosis (15%) and GI bleeding (9%). Patients were treated with various dosages and frequency. Prophylactic treatment with 10-30U/kg (pdFVII) or 20-30mcg/kg (rFVIIa) twice or three times/weeks was described to be effective. In the literature and in our experience, prophylaxis can be considered in patients with severe FVII deficiency and severe bleeding phenotype. A dose of 10-30U/kg (pdFVII) or 20-30 microg/kg (rFVIIa) twice or three times/week is usually administrated, but dose and frequency can be tailored based on the clinical follow-up of the patients. Since hemarthrosis is a frequent manifestation, a suggestion to improve the outcomes of patients with severe FVII deficiency is to monitor joint condition in order to identify early arthropathy that could be another indication to start secondary prophylaxis. © 2015 John Wiley & Sons Ltd.

Livestock systems play a key role in global sustainability challenges like food security and climate change, yet many unknowns and large uncertainties prevail. We present a systematic, spatially explicit assessment of uncertainties related to grazing intensity (GI), a key metric for assessing ecological impacts of grazing, by combining existing data sets on (a) grazing feed intake, (b) the spatial distribution of livestock, (c) the extent of grazing land, and (d) its net primary productivity (NPP). An analysis of the resulting 96 maps implies that on average 15% of the grazing land NPP is consumed by livestock. GI is low in most of the world's grazing lands, but hotspots of very high GI prevail in 1% of the total grazing area. The agreement between GI maps is good on one fifth of the world's grazing area, while on the remainder, it is low to very low. Largest uncertainties are found in global drylands and where grazing land bears trees (e.g., the Amazon basin or the Taiga belt). In some regions like India or Western Europe, massive uncertainties even result in GI > 100% estimates. Our sensitivity analysis indicates that the input data for NPP, animal distribution, and grazing area contribute about equally to the total variability in GI maps, while grazing feed intake is a less critical variable. We argue that a general improvement in quality of the available global level data sets is a precondition for improving the understanding of the role of livestock systems in the context of global environmental change or food security.

Profuse blood loss affects blood coagulation to various degrees. However, whether bleeding speed affects coagulation remains uncertain. This study aimed to evaluate the effect of bleeding speed on coagulation function. A total of 141 patients in the Department of Thoracic Surgery of our hospital were evaluated between January 2007 and February 2014. There are two groups of patients, those who received decortication for chronic encapsulated empyema were called the slow-bleeding group, and those who received thoracoscopic upper lobectomy were called the fast bleeding group; each group was further subdivided into three: group A, 1000 ml ≤ bleeding amount < 1500 ml; group B, 1500 ml ≤ bleeding amount < 1700 ml; group C, 1700 ml ≤ bleeding amount < 2000 ml. Then, coagulation function was assessed in all patients before and during surgery and at 1, 2, and 24 h after surgery, measuring prothrombin time, activated partial thromboplastin time (APTT), fibrinogen, blood pressure, hematocrit, hemoglobin, and platelets. Bleeding duration was overtly longer in the slow-bleeding group than that in quick bleeding individuals (2.3 ± 0.25 h vs. 0.41 ± 0.13 h, P < 0.001). Fibrinogen, hematocrit, hemoglobin, and platelets strikingly decreased, whereas prothrombin time and APTT values significantly increased with bleeding amounts in both quick and slow-bleeding groups. Interestingly, compared with slow-bleeding patients, coagulation indices at each time point and bleeding amounts had significant differences in the quick bleeding group.Increased consumption of coagulation factors in quick bleeding may have greater impact on coagulation function.

Objective To determine whether treatment outcome is associated with visualization of contrast extravasation in patients with acute massive gastrointestinal bleeding after endoscopic failure. Materials and Methods 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. Results 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 hemostasis (odds ratio [OR] = 28.66) is the most important predictor affecting the mortality in the two groups of patients. Conclusion Visualization of contrast extravasation on angiography usually can target the bleeding artery directly, resulting in a higher success rate to control of hemorrhage. PMID:21927558

G-protein-coupled receptors (GPCRs) are key regulators of skeletal homeostasis and are likely important in fracture healing. Because GPCRs can activate multiple signaling pathways simultaneously, we used targeted disruption of G(i) -GPCR or activation of G(s) -GPCR pathways to test how each pathway functions in the skeleton. We previously demonstrated that blockade of G(i) signaling by pertussis toxin (PTX) transgene expression in maturing osteoblastic cells enhanced cortical and trabecular bone formation and prevented age-related bone loss in female mice. In addition, activation of G(s) signaling by expressing the G(s) -coupled engineered receptor Rs1 in maturing osteoblastic cells induced massive trabecular bone formation but cortical bone loss. Here, we test our hypothesis that the G(i) and G(s) pathways also have distinct functions in fracture repair. We applied closed, nonstabilized tibial fractures to mice in which endogenous G(i) signaling was inhibited by PTX, or to mice with activated G(s) signaling mediated by Rs1. Blockade of endogenous G(i) resulted in a smaller callus but increased bone formation in both young and old mice. PTX treatment decreased expression of Dkk1 and increased Lef1 mRNAs during fracture healing, suggesting a role for endogenous G(i) signaling in maintaining Dkk1 expression and suppressing Wnt signaling. In contrast, adult mice with activated Gs signaling showed a slight increase in the initial callus size with increased callus bone formation. These results show that G(i) blockade and G(s) activation of the same osteoblastic lineage cell can induce different biological responses during fracture healing. Our findings also show that manipulating the GPCR/cAMP signaling pathway by selective timing of G(s) and G(i) -GPCR activation may be important for optimizing fracture repair. © 2015 American Society for Bone and Mineral Research.

Update on massive transfusion.

Massive haemorrhage requires massive transfusion (MT) to maintain adequate circulation and haemostasis. For optimal management of massively bleeding patients, regardless of aetiology (trauma, obstetrical, surgical), effective preparation and communication between transfusion and other laboratory services and clinical teams are essential. A well-defined MT protocol is a valuable tool to delineate how blood products are ordered, prepared, and delivered; determine laboratory algorithms to use as transfusion guidelines; and outline duties and facilitate communication between involved personnel. In MT patients, it is crucial to practice damage control resuscitation and to administer blood products early in the resuscitation. Trauma patients are often admitted with early trauma-induced coagulopathy (ETIC), which is associated with mortality; the aetiology of ETIC is likely multifactorial. Current data support that trauma patients treated with higher ratios of plasma and platelet to red blood cell transfusions have improved outcomes, but further clinical investigation is needed. Additionally, tranexamic acid has been shown to decrease the mortality in trauma patients requiring MT. Greater use of cryoprecipitate or fibrinogen concentrate might be beneficial in MT patients from obstetrical causes. The risks and benefits for other therapies (prothrombin complex concentrate, recombinant activated factor VII, or whole blood) are not clearly defined in MT patients. Throughout the resuscitation, the patient should be closely monitored and both metabolic and coagulation abnormalities corrected. Further studies are needed to clarify the optimal ratios of blood products, treatment based on underlying clinical disorder, use of alternative therapies, and integration of laboratory testing results in the management of massively bleeding patients.

Hospitals must have a major haemorrhage protocol in place and this should include clinical, laboratory and logistic responses. Immediate control of obvious bleeding is of paramount importance (pressure, tourniquet, haemostatic dressings). The major haemorrhage protocol must be mobilised immediately when a massive haemorrhage situation is declared. A fibrinogen < 1 g.l−1 or a prothrombin time (PT) and activated partial thromboplastin time (aPTT) of > 1.5 times normal represents established haemostatic failure and is predictive of microvascular bleeding. Early infusion of fresh frozen plasma (FFP; 15 ml.kg−1) should be used to prevent this occurring if a senior clinician anticipates a massive haemorrhage. Established coagulopathy will require more than 15 ml.kg−1 of FFP to correct. The most effective way to achieve fibrinogen replacement rapidly is by giving fibrinogen concentrate or cryoprecipitate if fibrinogen is unavailable. 1:1:1 red cell:FFP:platelet regimens, as used by the military, are reserved for the most severely traumatised patients. A minimum target platelet count of 75 × 109.l−1 is appropriate in this clinical situation. Group-specific blood can be issued without performing an antibody screen because patients will have minimal circulating antibodies. O negative blood should only be used if blood is needed immediately. In hospitals where the need to treat massive haemorrhage is frequent, the use of locally developed shock packs may be helpful. Standard venous thromboprophylaxis should be commenced as soon as possible after haemostasis has been secured as patients develop a prothrombotic state following massive haemorrhage. PMID:20963925

To evaluate the treatment effect of an antioxidant-essential oil gel on orthodontic patients with generalized gingivitis. The gel contains the essential oils menthol and thymol and the antioxidants ferulic acid and phloretin. Thirty patients from the university's orthodontic clinic were screened for gingivitis and randomly allocated into treatment and placebo-control groups. Each patient was evaluated at three orthodontic treatment visits (T1, T2, and T3). A periodontal examination, including probing depth (PD), bleeding on probing (BOP), gingival index (GI), and plaque index (PI) was performed at each visit. Between T1 and T2, patients were instructed to apply a topical gel (active or placebo) to their gingiva twice daily after brushing. From T2 to T3, patients were instructed to discontinue use of the gel. The treatment group showed statistically significant (P < .05) reductions of BOP (-13.6 percentage points) and GI (-0.14) between T1 and T2, and significant increases in BOP (13.3 percentage points) and GI (0.14) between T2 and T3. Except for an increase in the GI between T2 and T3, the control group showed no significant changes in BOP or GI over time. The only other significant changes that occurred pertained to the treatment group, which showed significant increases in PD (0.08 mm) and PI (0.18) between T2 and T3. Application of a topical antioxidant-essential oil gel is an effective means of reducing inflammation in orthodontic patients with gingivitis.

Gravitational Instabilities in Protostellar and Protoplanetary Disks

NASA Astrophysics Data System (ADS)

Durisen, R. H.; Mejia, A. C.; Pickett, B. K.

Self-gravity in fluid and particle systems is the primary mechanism for the creation of structure in the Universe on astronomical scales. The rapidly rotating Solar System-sized disks which orbit stars during the early phases of star and planet formation can be massive and thus susceptible to spontaneous growth of spiral distortions driven by disk self-gravity. These are called gravitational instabilities (GI's). They can be important sources of mass and angular momentum transport due to the long-range torques they generate; and, if strong enough, they may fragment the disk into bound lumps with masses in therange of gas giant planets and brown dwarfs. My research group has been using numerical 3D hydrodynamics techniques to study the growth and nonlinear behavior of GI's in disks around young stars. Our simulations have demonstrated the sensitivity of outcomes to the thermal physics of the disks and have helped to delineate conditions conducive to the formation of dense clumps. We are currently concentrating our efforts on determining how GI's affect the long-term evolution and appearance of young stellar disks, with the hope of finding characteristic GI signatures by which we may recognize their occurrence in real systems.

Gas gangrene of the abdominal wall is a rare clinical occurrence with high rates of morbidity and mortality. The primary source of the infection is often unknown. To analyze the primary underlying intestinal etiologies and diagnostic approaches of gas gangrene of the abdominal wall, and to highlight specific treatment problems, particularly that of constructing a colostomy exteriorized through a massively infected abdominal wall. Seven cases of abdominal wall gas gangrene due to a gastrointestinal etiology were identified. (Cases arising from proctologic sources or related to recent abdominal surgery were excluded.) During the same period, 39 other patients presenting with abdominal wall gangrene from non-intestinal sources were treated. The etiologies were: perforated sigmoid diverticulitis (n=2), perforated appendicitis (n=1), acute pancreatitis with associated cecal perforation (n=1), and perforated colorectal cancer (n=3). Four of the seven patients died despite treatment (mortality of 57%). The clinical presentations of these seven cases demonstrate that a GI source must be suspected whenever a patient presents with abdominal wall gas gangrene, even when there are no specific GI symptoms. Imaging, particularly with CT scan, is essential both to visualize the extent of tissue necrosis and to reveal underlying primary GI pathology. This optimizes the surgical approach both by allowing for complete debridement and drainage of infected tissue, and by focussing the intervention on correction of the underlying primary GI source of infection.

An approach to transfusion and hemorrhage in trauma: current perspectives on restrictive transfusion strategies

Hemorrhagic shock is a leading cause of death in trauma patients. Surgical control of bleeding and fluid resuscitation with both crystalloid and blood products remain the mainstay of therapy for injured patients with bleeding. However, there has been a recent re-evaluation of transfusion practice. Both the fear of transmissible disease and the costs of transfusing blood products have led to increasingly restrictive transfusion practices. A small percentage of trauma patients require massive transfusion. These patients are complex and difficult to manage, and clinicians must act quickly to save them. There is little evidence to help guide clinical transfusion decisions in these patients. A rational approach to using blood products requires an understanding of the end points of resuscitation. Resuscitation with fluids and red cells is necessary to improve perfusion and oxygen delivery to tissues. Avoiding overtransfusion is key, however, because transfusion is also associated with significant risks. This trend toward reducing allogenic blood exposure will likely continue. New technologies that have the potential of reducing blood loss and transfusion requirements in trauma patients with massive bleeding are being developed, and similar old technologies are being reapplied.

In 2007, "the Guidelines for Actions against Intraoperative Critical Hemorrhage" were established by the Japanese Society of Anaesthesiologists and the Japanese Society of Blood transfusion and Cell Therapy. The documentation of in-hospital procedures for critical hemorrhage, especially about how to select RBC units, has widely standardized hospital practice. Patients with intraoperative critical hemorrhage sometimes suffer from massive blood loss. In this situation, some patients develop coagulopathy. To treat them, we need to evaluate their coagulation status based on laboratory test results. So, we performed a nationwide questionnaire survey on the current status of hospital clinical laboratories evaluating critical hemorrhage. From the results of this survey, it was recommended that central hospital laboratories should try to reduce the turn-around time required to test for coagulation parameters as much as possible for appropriate substitution therapy.

A survey study of the efficacy and side-effects of loxoprofen in orthopaedic outpatient clinics was carried out from January 1995 to December 1997. There were 1206 patients (569 males and 637 females) with an average age of 56.4 +/- 14.9 years. The youngest was 43 and the oldest was 79 years. About 36 per cent of the patients had underlying diseases and 31 per cent were receiving other medications as well as loxoprofen. About 91 per cent of the patients were satisfied with loxoprofen in terms of pain control and decreased inflammation. However, 8.4 per cent had side-effects, the most common being GI and CNS disturbances. Some patients (0.24%) had GI bleeding and needed hospitalization. The high risk patients were female older than 60 years who had used loxoprofen continuously for more than 6 weeks. However, we conclude that loxoprofen is an effective NSAID with few side-effects.

Extraskeletal osteosarcoma (EOS) is a highly aggressive and rare malignant soft tissue tumor, characterized by the production of neoplastic osseous tissue without attachment to the bone or periosteum. It rarely involves the visceral organs. Only 3 cases of mesenteric EOS have been reported in English literature. Here, we describe a male patient of 40 years, who was diagnosed to have EOS arising from small bowel mesentery. This patient presented with lower gastrointestinal (GI) bleeding. Upper GI endoscopy and colonoscopy were normal. Computed tomography scan demonstrated a well defined multi-loculated mixed density mass lesion measuring about 13x7x7 cm in lower abdomen adjacent to small bowel loops with liver metastasis. Palliative en bloc resection of tumor with adjacent small bowel was performed. The histopathology revealed a telangiectatic type osteosarcoma of mesentery. Diagnosis of EOS, its management and the outcome in context of the current literature are discussed.

Nonulcer causes of bleeding are often regarded as minor, ie, associated with a lower risk of mortality. To assess the risk of death from nonulcer causes of upper GI bleeding (UGIB). Secondary analysis of prospectively collected data from 3 national databases. Community and teaching hospitals. Consecutive patients admitted for acute nonvariceal UGIB. Early endoscopy, medical and endoscopic treatment as appropriate. Thirty-day mortality, recurrent bleeding, and need for surgery. A total of 3207 patients (65.8% male), mean (standard deviation) age 68.3 (16.4) years, were analyzed. Overall mortality was 4.45% (143 patients). According to the source of bleeding, mortality was 9.8% for neoplasia, 4.8% for Mallory-Weiss tears, 4.8% for vascular lesions, 4.4% for gastroduodenal erosions, 4.4% for duodenal ulcer, and 3.1% for gastric ulcer. Frequency of death was not different among benign endoscopic diagnoses (overall P = .567). Risk of death was significantly higher in patients with neoplasia compared with benign conditions (odds ratio 2.50; 95% CI, 1.32-4.46; P < .0001). Gastric or duodenal ulcer significantly increased the risk of death, but this was not related to the presence of high-risk stigmata (P = .368). The strongest predictor of mortality for all causes of nonvariceal UGIB was the overall physical status of the patient measured with the American Society of Anesthesiologists score (1-2 vs 3-4, P < .001). No data on the American Society of Anesthesiologists class score in the Prometeo study. Nonulcer causes of nonvariceal UGIB have a risk of death, similar to bleeding peptic ulcers in the clinical context of a high-risk patient.

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

A simple and safe method of nonsurgical treatment for the control of massive acute gastric mucosal hemorrhage is described. The procedure was developed from experimental and clinical observations that the presence of gastric hydrocloric acid played an important part in the development and perpetuation of the entity. The treatment consists of complete neutralization of gastric acid with antacid to a pH of 7. The antacid is intermittently added and aspirate at 7. In a retrospective analysis, the hemorrhage was controlled in 44 of 49 patients (89%). Five patients who continued to bleed underwent surgery (10%). Three patients had vagotomy and pyloroplasty and their bleeding ceased without recurrence. Two patients underwent partial gastrectomy, but they developed recurrent bleeding and died. One patient whose bleeding has been controlled by vagotomy and pyloroplasty died without hemorrhage 10 days after operation. Of the 44 patients whose bleeding had been controlled by antacid, 11 patients died without hemorrhage one or more weeks later. These results of 89% control of hemorrhage compare favorably with those in the literature.

Gastrointestinal (GI) symptoms pose a significant burden to patients receiving chemoradiation therapy (CRT) for anal cancer; however, the impact of symptoms from the patient perspective has not been quantified. This retrospective study examined and compared patient and clinician reports of acute GI toxicity during CRT. Patients treated with definitive RT using intensity-modulated radiation therapy for anal cancer between 9/09 and 11/12 were reviewed. Median RT dose was 56 Gy (range 45-56), and 76 patients (97%) received concurrent 5-fluorouracil-based chemotherapy. During RT, patients completed the 7-item Bowel Problem Scale (BPS) weekly. Clinicians assessed toxicity separately using CTCAE v. 3.0. Scores of BPS ≥ 3 and CTCAE ≥ 1 were considered to be clinically meaningful. Agreement of the two assessments was evaluated by Cohen's kappa coefficient. Seventy-eight patients completed at least one BPS and had a corresponding clinician assessment. Patients reporting scores of ≥3 was highest at week 5 (n = 68) for diarrhea (44.1%), proctitis (57.4%), and mucus (48.4%), while urgency (47.6%), tenesmus (31.7%), and cramping (27%) were highest at week 4 (n = 63). Baseline bleeding scores (26.7%; score ≥3) improved during treatment (13.4% at week 5). "Poor" agreement was observed between patient- and clinician-reported proctitis (Cohen's k = 0.11; n = 58); however, there was "good" agreement for diarrhea (Cohen's k = 0.68; n = 58). Acute GI toxicity during definitive CRT for anal cancer was most significant during weeks 4-5, while rectal bleeding improved during treatment. Discrepancies in patient- and clinician-reported symptoms demonstrate the potential for patient-reported outcomes to be useful tools for anal cancer clinical assessments.

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 over the 3-year period between December 2002 and December 2005 at our institution, were retrospectively reviewed. Five patients with severe enteric bleeding underwent angiography and endovascular repair. Four presented primary arterioenteric fistulas, and one presented a secondary aortoenteric fistula. All had massive persistent bleeding with hypotension despite volume substitution and transfusion by the time of endovascularmore » management. Outcome after treatment of these patients was investigated for major procedure-related complications, recurrence, reintervention, morbidity, and mortality. Mean follow-up time was 3 months (range, 1-6 months). All massive bleeding was controlled by occlusive balloon catheters. Four fistulas were successfully sealed with stent-grafts, resulting in a technical success rate of 80%. One patient was circulatory stabilized by endovascular management but needed immediate further open surgery. There were no procedure-related major complications. Mean hospital stay after the initial endovascular intervention was 19 days. Rebleeding occurred in four patients (80%) after a free interval of 2 weeks or longer. During the follow-up period three patients needed 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 arterioenteric fistulas in the emergent episode. However, in this group of patients with severe comorbidities, the risk of rebleeding is high and further intervention must be considered. Patients with cancer may only need treatment for the acute bleeding episode, and an endovascular approach has the advantage of low morbidity.« less

BACKGROUND AND AIM: Severe bleeding from gastrointestinal ulcers is a life-threatening event that is difficult to manage when endoscopic treatment fails. Transcatheter embolization has been suggested as an alternative treatment in this situation. The present study reports on the efficacy and long-term outcomes of transcatheter embolization after failed endoscopic treatments were assessed in high-operative-risk patients. METHODS: A retrospective review of 60 consecutive emergency embolization procedures in hemodynamically unstable patients (41 men, 19 women; mean [±SD] age 69.4±15 years) was conducted. Patients were referred for selective angiography between 1999 and 2008 after failed endoscopic treatment of massive bleeding from gastrointestinal ulcers. Mean follow-up was 22 months. RESULTS: Embolization was feasible and successful in 57 patients. Sandwich coiling of the gastroduodenal artery was used in 34 patients, and superselective occlusion of the terminal feeding artery (with glue, coils or gelatin particles) was used in 23 patients. Early rebleeding occurred in 16 patients and was managed with endoscopy (n=8), reembolization (n=3) or surgery (n=5). No major embolization-related complications occurred. Sixteen patients died within 30 days after embolization (including three who died from rebleeding) and 11 died thereafter. No late bleeding recurrences were reported. CONCLUSIONS: Selective angiographic embolization is safe and effective for controlling life-threatening bleeding from gastroduodenal ulcers. The procedure usually obviates the need for emergency surgery in these high-risk patients. Survival depends chiefly on underlying conditions. PMID:19214287

Objectives Postoperative bleeding represents a life-threatening complication after pancreatic surgery. Recent developments in interventional radiology have challenged the role of surgery in bleeding control. This study aimed to assess the management of major haemorrhagic complications after pancreatic surgery at a tertiary referral centre. Methods Between August 1998 and June 2009, 18 patients with major bleeding after pancreatic surgery were admitted to the University Hospital of Zurich, Zurich, Switzerland. We retrospectively analysed their medical charts, focusing on diagnosis, therapy and outcome. Results Major arterial bleeding occurred after a median postoperative interval of 21.5 days (range: 9–259 days). Seventeen patients demonstrated various symptoms, such as repeated upper gastrointestinal bleeding or haemorrhagic shock. Diagnosis was usually made by contrast-enhanced computed tomography (CT). Leakage of the pancreaticojejunostomy caused the formation of a pseudoaneurysm in 78% of patients. Haemostasis was achieved in 10 patients by interventional radiology. Two patients died of massive re-bleeding. Six patients underwent primary emergency surgery, which five did not survive. Conclusions Delayed bleeding after pancreatic surgery is suspicious for a pseudoaneurysm. Contrast-enhanced CT followed by early angiography provides accurate diagnosis and treatment. Interventional radiological treatment should be preferred over primary surgery because it is currently the most life-saving approach. PMID:21241431

Dieulafoy's disease is an uncommon condition, the usual site of occurrence being the gastrointestinal tract. The condition refers to the presence of a dysplastic submucosal artery with mucosal vascular branches that has propensity to cause recurrent bleeding. Dieulafoy's disease of the bronchus is rare. Herein, we describe the case of a 26-year-old male who presented with recurrent bouts of hemoptysis and bronchial Dieulafoy's disease was diagnosed. Flexible bronchoscopy was performed, and argon plasma coagulation (APC) of the bleeding lesion was done. The procedure was successful and was followed by complete eradication of the vascular malformation and cessation of hemoptysis. APC is a useful tool in the armamentarium of an interventional pulmonologist that can allow rapid and safe control of bleeding from superficially located and bleeding endobronchial lesions, and can be easily and effectively applied using a flexible bronchoscope.

To define the risk factors of complications which are followed by re-operations in patients with cardiac and pericardial wounds and to prevent these complications. Retrospective and prospective analysis of 1072 victims with cardiac and pericardial injuries for 35 years was performed. Overall mortality was 17.2%. 98 patients died during surgery. Postoperative bleeding was observed in 38 (3.9%) cases. In 28 cases re-operations were performed for bleeding-related complications. Indications for re-thoracotomy were one-time drainage from pleural cavity over 500 ml or bleeding rate over 100 ml per hour for 4 hours. Prevention of postoperative bleeding in case of cardiac and pericardial wounds was developed on basis of analysis of these observations. Risk factors of complications requiring re-operation are cardiomyopathy of different etiology, technical and tactical errors during primary intervention and hypocoagulation with massive blood loss. Prevention of these complications includes careful heart wound closure, comprehensive intraoperative control, correction of hemostatic system.

Lower GI hemorrhage is a common source of morbidity and mortality. Tranexamic acid is an antifibrinolytic that has been shown to reduce blood loss in a variety of clinical conditions. Information regarding the use of tranexamic acid in treating lower GI hemorrhage is lacking. The aim of this trial was to determine the clinical efficacy of tranexamic acid when used for lower GI hemorrhage. This was a prospective, double-blind, placebo-controlled, randomized clinical trial. The study was conducted at a tertiary referral university hospital in Australia. Consecutive patients aged >18 years with lower GI hemorrhage requiring hospital admission from November 2011 to January 2014 were screened for trial eligibility (N = 265). A total of 100 patients were recruited after exclusions and were randomly assigned 1:1 to either tranexamic acid or placebo. The primary outcome was blood loss as determined by reduction in hemoglobin levels. The secondary outcomes were transfusion rates, transfusion volume, intervention rates for bleeding, length of hospital stay, readmission, and complication rates. There was no difference between groups with respect to hemoglobin drop (11 g/L of tranexamic acid vs 13 g/L of placebo; p = 0.9445). There was no difference with respect to transfusion rates (14/49 tranexamic acid vs 16/47 placebo; p = 0.661), mean transfusion volume (1.27 vs 1.93 units; p = 0.355), intervention rates (7/49 vs 13/47; p = 0.134), length of hospital stay (4.67 vs 4.74 d; p = 0.934), readmission, or complication rates. No complications occurred as a direct result of tranexamic acid use. A larger multicenter trial may be required to determine whether there are more subtle advantages with tranexamic acid use in some of the secondary outcomes. Tranexamic acid does not appear to decrease blood loss or improve clinical outcomes in patients presenting with lower GI hemorrhage in the context of this trial. see Video Abstract at http://links.lww.com/DCR/A453.

This randomized clinical trial investigated the influence of the utilization time of brush heads from different types of power toothbrushes [oscillating rotating (OR) and sonic action (SA)93; on oral hygiene (plaque accumulation and gingival inflammation) over a 6-month observation period. 49 participants were randomly allocated into two groups: use of the same brush head over 6 months (NR: non-replacement) or replacement of brush head every 4 weeks over 6 months (R: replacement). Each group was subdivided into two subgroups according to kind of toothbrush (TB) used (OR and SA). Modified Quigley-Hein plaque index (QHI), papilla bleeding index (PBI), and gingival index (GI) were recorded at baseline and 2, 8, 12, 16, and 24 weeks after baseline. After 24 weeks, participants of both groups (R and NR) received a new brush head. At week 26, final QHI, PBI, and GI were recorded. QHI decreased between baseline and follow-up visits in R groups (P< 0.05), with the exception of week 12 (P= 0.26). In NR groups, no significant decrease was detected (P> 0.05). There was no significant effect of time on PBI or GI in any of R subgroups (P> 0.05). In NR oscillating/rotating TB: significant increase in PBI and GI was detected 24 weeks after baseline (PBI: P= 0.02, GI: P= 0.03); sonic action TBs showed significant decrease in PBI at every follow-up visit (P< 0.05), except at 24 weeks after baseline (P= 0.73). GI was significantly decreased at 2 weeks after baseline only (P< 0.01). Six-month use of the same brush head reduced effectiveness in removing plaque, and gingival inflammation appeared to increase after a utilization time of over 4 months. Replacing brush heads is advised after 4 months.

Hemobilia secondary to gallbladder polyposis is rare in children but has been reported in a few children with metachromatic leukodystrophy. We present a case with preoperative multidetector computed tomography (MDCT) diagnosis of massive hemobilia caused by gallbladder polyposis in a patient with metachromatic leukodystrophy. Our report highlights the importance of both awareness of the association of gallbladder polyposis with other syndromes such as metachromatic leukodystrophy as well as the possibility of this entity presenting with life-threatening bleeding.

Pseudoaneurysm is a serious complication after pancreatic surgery, which mainly depends on the presence of a preceding pancreatic fistula. Postpancreatectomy hemorrhage following total pancreatectomy is a rare complication due to the absence of a pancreatic fistula. Here we report an unusual case of massive gastrointestinal bleeding due to right hepatic artery (RHA) pseudoaneurysm following total remnant pancreatectomy. A 75-year-old man was diagnosed with intraductal papillary mucinous carcinoma recurrence following distal pancreatectomy and underwent total remnant pancreatectomy. After discharge, he was readmitted to our hospital with melena because of the diagnosis of gastrointestinal bleeding. Gastrointestinal endoscopy was performed to detect the origin of bleeding, but an obvious bleeding point could not be detected. Abdominal computed tomography demonstrated an expansive growth, which indicated RHA pseudoaneurysm. Emergency angiography revealed gastrointestinal bleeding into the jejunum from the ruptured RHA pseudoaneurysm. Transcatheter arterial embolization was performed; subsequently, bleeding was successfully stopped for a short duration. Because of improvements in his general condition, the patient was discharged. To date, very few cases have described postpancreatectomy hemorrhage following total remnant pancreatectomy. We suspect that the aneurysm ruptured into the jejunum, possibly because of the scarring and inflammation associated with his two complex surgeries. Pseudoaneurysm should be considered when the fragility of blood vessels is suspected, despite no history of anastomotic leak and intra-abdominal abscess. Our case also highlighted that detecting gastrointestinal bleeding is necessary to recognize sentinel bleeding if the origin of bleeding is undetectable.

To summarize the available evidence on the issues in health economics related to oral anticoagulation for stroke prevention in atrial fibrillation (AF) in the US. A literature review was performed using PubMed, EMBASE, Cochrane Library, and International Pharmaceutical Abstracts, as well as the websites of professional organizations. The search was conducted according to a prespecified protocol, limiting articles to those published in English from 2001 to October 2012 and focused on the economics associated with AF and AF-related stroke in the US. Data from 27 studies were extracted and included in the review. Strokes in patients with AF are more debilitating and have higher recurrence rates and mortality compared with strokes unrelated to AF. However, data describing the long-term cost of AF-related stroke and stroke subtypes remain limited. The costs of major gastrointestinal (GI) bleeding and intracranial bleeding related to warfarin are significant, whereas the costs of the more frequent minor GI bleeding are relatively low. Overall, the cost-effectiveness of warfarin versus aspirin or no treatment in patients with at least 1 risk factor for stroke is well established. Economic evaluations based on results from randomized controlled clinical trials generally found that new anticoagulants were a cost-effective alternative to warfarin for stroke prevention in AF. However, these cost-effectiveness results are highly sensitive to how well optimal international normalized ratio control is maintained (within target of 2.0-3.0) for warfarin and the time horizon used for analysis. Time in therapeutic range for warfarin in routine clinical practice was lower than in clinical trials, as shown by previous studies. This review identified several areas of uncertainty regarding the economic benefit of anticoagulants. The generalizability of cost-effectiveness results of anticoagulant therapy in AF based on clinical trial data must be confirmed by comparative effectiveness research conducted in the real-world setting.

Periodontal diseases, which result from inflammation of tooth supporting tissues, are highly prevalent worldwide. Myeloperoxidase (MPO), from certain white blood cells in saliva, is a biomarker for inflammation. We report our study on the salivary MPO activity and its association with severity of periodontal diseases among Thai patients. Periodontally healthy subjects (n = 11) and gingivitis (n = 32) and periodontitis patients (n = 19) were enrolled. Assessments of clinically periodontal parameters were reported as percentages for gingival bleeding index (GI) and bleeding on probing (BOP), whereas pocket depth (PD) and clinical attachment loss (CAL) were measured in millimeters and then made to index scores. Salivary MPO activity was measured by colorimetry using 3,3'-diaminobenzidine as substrate. The results showed that salivary MPO activity in periodontitis patients was significantly higher than in healthy subjects (p = 0.003) and higher than in gingivitis patients (p = 0.059). No difference was found between gingivitis and healthy groups (p = 0.181). Significant correlations were observed (p < 0.01) between salivary MPO activity and GI (r = 0.632, p < 0.001), BOP (r = 0.599, p < 0.001), PD (r = 0.179, p = 0.164), and CAL (r = 0.357, p = 0.004) index scores. Sensitivity (94.12%), specificity (54.55%), and positive (90.57%) and negative (66.67%) predictive values indicate that salivary MPO activity has potential use as a screening marker for oral health of the Thai community.

To study whether in vitrofertilization (IVF) treatment has any effect on women's preexisting periodontal status and, if pre-existing women's periodontal status has any impact on IVF outcomes, such as superovulation for multiple follicles maturation, oocyte retrieval and embryo transfer, as well as on pregnancy and its outcomes. Sixty women aged 29 to 41 years were recruited in the study. Gingival inflammation (simplified gingival index, GI-S), plaque levels (plaque control record index, PCR), bleeding on probing (BOP) and probing depth (PD), were recorded for all participants before and after IVF. Blood tests were performed prior to IVF. A statistically significant increase in GI-S after IVF was observed in all women (31.9 +/- 18.7% to 61.7 +/- 23.5%), and was higher in women with gingivitis (37.1 +/- 5.7% to 77.6 +/- 6.7%). Women with periodontitis demonstrated a statistically significant increase in BOP (67.7 +/- 6.6% to 89.5 +/- 7.1%), and in the sum of probing pocket depths (from 243.8 +/- 56.2 mm to 250.5 +/- 58.3 mm). A trend for negative correlation between the number of follicles and transferred embryos and the gingival index, before and after IVF respectively, was recorded in all women. There was a similar trend with bleeding on probing after IVF in women with periodontitis. Periodontal clinical parameters worsened in women undergoing IVF treatment. On the other hand, a poor pre-existing periodontal status seems to be associated with poorer outcomes of IVF treatment.

Upper GI bleeding (UGIB) is a potentially life threatening gastrointestinal emergency whose effective management depends on early risk stratification. We retrospectively studied 151 patients admitted to our unit with UGIB between 1st January 2007 and 31st December 2011 and in whom we calculated the clinical and complete Rockall, the Glasgow-Blatchford and modified Glasgow-Blatchford risk scores. We performed an analysis of the predictive value of these scores for in-hospital mortality and need for clinical intervention. Of the 151 patients enrolled, 68.87% were male, and the mean age was 59.48 years. One in three patients had a history of chronic liver disease and one in eight had a previous episode of UGIB. Clinically, 58.3% of the patients presented with melena, 18.5% with hematemesis and 23.1% with both hematemesis and melena. 22% of cases were variceal hemorrhages and the other non-variceal. 16 patients died during hospitalization. The prognostic accuracy of all four scores for in-hospital death and need for clinical intervention was good, the complete Rockall score having the best performance (AUROC 0.849 and 0.653 respectively). The Rockall and Blatchford scores were good predictors of mortality and need for clinical intervention in our study. The good predictive performance of these scores highlight the need for their use in day-to-day practice to select patients with likelihood of poor clinical outcome. Celsius.

The first episode of variceal bleeding is one of the most frequent causes of death in patients with liver cirrhosis. The Child-Pugh(CP) scoring system has been widely accepted for prognostic assessment. Recently, MELD has been known to be better than the CP scoring system for predicting mortality in patients with end-stage liver diseases. The Rockall risk scoring system was developed to predict the outcome of upper GI bleeding including variceal bleeding. The aim of this study was to investigate the mortality rate of first variceal bleeding and the predictability of each scoring system. We evaluated the 6-week mortality rate, rebleeding rate, and 1-year mortality rate of all the 136 patients with acute variceal bleeding without previous episode of hemorrhage between January 1, 1998 and December 31, 2000. The CP score, MELD score, and Rockall score were estimated and analyzed. Among 136 patients, 35 patients with hepatoma and 8 patients with follow-up loss were excluded. Six-week mortality rate, 1-year mortality rate, and rebleeding rate of first variceal bleeding were 24.7%, 35.5%, and 12.9%, respectively. The c-statistics of CP, MELD, and Rockall score for predicting 6-week mortality rate were 0.809 (p<0.001, 95% CI, 0.720-0.898), 0.804 (p<0.001, 95% CI, 0.696-0.911), 0.787 (p<0.001, 95% CI, 0.683-0.890), respectively. For 1-year mortality rate, c-statistics were 0.765 (p<0.005, 95% CI, 0.665-0.865), 0.780 (p<0.005, 95% CI, 0.676-0.883), 0.730 (p<0.01, 95% CI, 0.627-0.834), respectively. The CP, MELD, and Rockall scores were reliable measures of mortality risk in patients with first variceal bleeding. The CP classification is useful in its easy applicability.

Rubber band ligation of hemorrhoids: A guide for complications

PubMed Central

Albuquerque, Andreia

2016-01-01

Rubber band ligation is one of the most important, cost-effective and commonly used treatments for internal hemorrhoids. Different technical approaches were developed mainly to improve efficacy and safety. The technique can be employed using an endoscope with forward-view or retroflexion or without an endoscope, using a suction elastic band ligator or a forceps ligator. Single or multiple ligations can be performed in a single session. Local anaesthetic after ligation can also be used to reduce the post-procedure pain. Mild bleeding, pain, vaso-vagal symptoms, slippage of bands, priapism, difficulty in urination, anal fissure, and chronic longitudinal ulcers are normally considered minor complications, more frequently encountered. Massive bleeding, thrombosed hemorrhoids, severe pain, urinary retention needing catheterization, pelvic sepsis and death are uncommon major complications. Mild pain after rubber band ligation is the most common complication with a high frequency in some studies. Secondary bleeding normally occurs 10 to 14 d after banding and patients taking anti-platelet and/or anti-coagulant medication have a higher risk, with some reports of massive life-threatening haemorrhage. Several infectious complications have also been reported including pelvic sepsis, Fournier’s gangrene, liver abscesses, tetanus and bacterial endocarditis. To date, seven deaths due to these infectious complications were described. Early recognition and immediate treatment of complications are fundamental for a favourable prognosis. PMID:27721924

Hepatic hemorrhage can be devastating, especially in patients with underlying hepatic pathology. This is a case report of a 50-year-old man who presented to the emergency room with Stage 3 shock as evidenced by a systolic blood pressure of 90 mmHg, a heart rate of 125 beats per minute, respiration of 32, with delayed capillary refill and agitation. At this time, he was found to have a massive spontaneous intra-abdominal hemorrhage with an advanced stage of amyloidosis with multiple organ malfunctions. The initial diagnosis was based on an abdominal computed tomography scan and the patient was taken expeditiously to a hybrid angiography suite for a celiac angiogram. An intraoperative diagnosis of extravasation from amyloid related vasculopathy was made based on the angiographic appearance of hepatic circulation. Coil embolization of the feeding branch of the bleeder was achieved using the interlock coil system and a completion angiogram was done showing complete cessation of active bleeding. The postoperative phase was uneventful and the patient was discharged home on postoperative day three. His postoperative visit at five months later was unremarkable. © The Author(s) 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Postpartum hemorrhage (PPH) is associated with maternal morbidity and mortality and has an increasing incidence in high-resource countries, despite dissemination of guidelines, introduction of skills training, and correction for risk factors. Current guidelines advise the administration, as fluid resuscitation, of almost twice the amount of blood lost. This advice is not evidence-based and could potentially harm patients. All women attending the outpatient clinic who are eligible will be informed of the study; oral and written informed consent will be obtained. Where there is more than 500 ml blood loss and ongoing bleeding, patients will be randomized to care as usual, fluid resuscitation with 1.5-2 times the amount of blood loss or fluid resuscitation with 0.75-1.0 times the blood loss. Blood loss will be assessed by weighing all draping. A blood sample, for determining hemoglobin concentration, hematocrit, thrombocyte concentration, and conventional coagulation parameters will be taken at the start of the study, after 60 min, and 12-18 h after delivery. In a subgroup of women, additional thromboelastometric parameters will be obtained. Our hypothesis is that massive fluid administration might lead to a progression of bleeding due to secondary coagulation disorders. In non-pregnant individuals with massive blood loss, restrictive fluid management has been shown to prevent a progression to dilution coagulopathy. These data, however, cannot be extrapolated to women in labor. Our objective is to compare both resuscitation protocols in women with early, mild PPH (blood loss 500-750 ml) and ongoing bleeding, taking as primary outcome measure the progression to severe PPH (blood loss > 1000 ml).

A common national MTP was jointly implemented in 2011 by the national blood service (Blood Services Group) and seven participating acute hospitals to provide rapid access to transfusion support for massively haemorrhaging patients treated in all acute care hospitals. Through a systematic clinical workflow, blood components are transfused in a ratio of 1:1:1 (pRBC: whole blood-derived platelets: FFP), together with cryoprecipitate for fibrinogen replacement. The composition of components for the MTP is fixed, although operational aspects of the MTP can be adapted by individual hospitals to suit local hospital workflow. The MTP could be activated in support of any patient with critical bleeding and at risk of massive transfusion, including trauma and non-trauma general medical, surgical and obstetric patients. There were 434 activations of the MTP from October 2011 to October 2013. Thirty-nine per cent were for trauma patients, and 30% were for surgical patients with heavy intra-operative bleeding, with 25% and 6% for patients with gastrointestinal bleeding and peri-partum haemorrhage, respectively. Several hospitals reported reduction in mean time between request and arrival of blood. Mean transfusion ratio achieved was one red cell unit: 0·8 FFP units: 0·8 whole blood-derived platelet units: 0·4 units of cryoprecipitate. Although cryoprecipitate usage more than doubled after introduction of MTP, there was no significant rise in overall red cells, platelet and FFP usage following implementation. This successful collaboration shows that shared transfusion protocols are feasible and potentially advantageous for hospitals sharing a central blood provider. © 2015 International Society of Blood Transfusion.

This study aims to evaluate the efficacy and safety of ultrasound-accelerated catheter-directed thrombolysis (UACDT) in the treatment of massive and submassive pulmonary embolism (PE). We conducted a prospective, observational cohort study of consequtive patients with massive or submassive PE treated with low-dose UACDT using EKOS EkoSonic® system at single center from May 2014 until April 2015. Overall, thirty-eight patients (median age, 64.5 years) were included. The primary safety outcomes were change in right ventricular (RV) to left ventricular (LV) diameter ratio within 24 hours of procedure initiation, at 1- and 6-month follow-up and major bleeding within 96 hours of the procedure initiation. BNP, troponin and D-dimer levels were also measured. The ultrasound-accelerated thrombolytic catheters were bilaterally placed in 25 (65.8%) patients. The median tissue plasminogen activator (tPA) dose for all patients in our study was 21.0 mg and the median infusion time was 15 hours. Measurements before and after treatment showed a decrease in pulmonary artery pressure. The median value of RV/LV diameter ratio decreased from 0.9 (0.7-1.1) at baseline to 0.7 (0-0.97) at 6-month follow-up (P=0.001) and pulmonary artery pressure from 61.4 ±16.7 to 37.2±9.1 mmHg (P=0.001). The median BNP level at baseline was 169 (29-721) pg/mL and 45.5 (0-328) pg/mL at 6 month follow-up (P=0.001). Of 38 patients with PE, one had intracranial hemorrage, one gastrointestinal bleeding and two developed puncture site bleeding. This prospective study provides alternative treatment option and an addition to the treatment algorithm for the management of pulmonary embolism.

The aim of this study was to investigate the common etiologies, clinical and biological patterns of upper gastrointestinal bleeding (UGIB) in children from a hospital center in Northeast Romania. This seven-year retrospective study was performed from 2007 to 2013 in St. Mary Children's Emergency Hospital, Jassy, Romania and included all children who referred to our center with UGIB exteriorized by hematemesis or melena. Endoscopy was performed under conscious sedation/general anesthesia after the informed consent was obtained. One hundred and three patients aged 1-18 years were included in this study. There were 57 males and 46 females with male to female ratio 1.2:1; 43.69% presented with hematemesis, 31.07% had melena and 25.24% had both. The most common causes of UGIB were erosive gastritis (33.98%), followed by esophagitis (14.56%), duodenitis (11.65%), duodenal ulcer (10.68%), gastric ulcer (5.83%), esophageal varices (4.85%), Mallory-Weiss syndrome (1.94%); multiple etiologies counted for 16.50% cases. A certain bleeding source was found in 34.95% cases, a possible one in 39.81% of the patients; the source could not be ascertained in 25.24% of cases. Nonsteroidal anti-inflammatory drug (NSAID) consumption was documented in in 17.51% of patients. The incidence of H. pylori infection was 36.89%. The most common cause of of upper GI bleeding in our series was gastritis, followed by oesophagitis and duodenitis. Most of the patients presented with hematemesis; previous consumption of NSAIDs and H. pylori infection were associated with gastroduodenal ulceration and bleeding. Early endoscopy was associated with a higher detection rate of the bleeding source.

The management of trauma patients suffering from active bleeding has improved with a better understanding of trauma-induced coagulopathy. The aim of this manuscript is to give recommendations for coagulation management. A systematic literature search in the PubMed database was performed for articles published between January 2000 and August 2009. A total of 230 articles were included in the present systematic review. The "coagulopathy of trauma" is a discrete disease which has a decisive influence on survival. Diagnosis and therapy of deranged coagulation should start immediately after admission to the emergency department. A specific protocol for massive transfusion should be introduced and continued. Loss of body temperature should be prevented and treated. Acidaemia should be prevented and treated by appropriate shock therapy. If massive transfusion is performed using fresh frozen plasma (FFP), a ratio of FFP to pRBC (packed red blood cells) of 1:2-1:1 should be achieved. Fibrinogen should be substituted at levels of <1.5 g/L. For patients suffering from active bleeding, permissive hypotension (i.e. mean arterial pressure ~65 mmHg) may be aimed for until surgical cessation of bleeding. This option is contraindicated in injuries of the central nervous system and in patients with coronary heart disease, or with known hypertension. Thrombelastography or -metry may be performed to guide coagulation diagnosis and substitution. Hypocalcaemia <0.9 mmol/L should be avoided and may be treated. For actively bleeding patients, pRBC may be given at haemoglobin <10 g/L (6.2 mmol/L) and haematocrit may be targeted at 30%.

A 62-year-old man with a chief complaint of dysphagia visited our hospital. Enhanced computed tomography showed the tumor near the duodenal wall and lymphadenopathy in the left supraclavicular fossa and para-aortic lymph node. Upper gastrointestinal endoscopy showed an ulcer accompanied with a fistula in the anterior wall of duodenal bulb, suggesting that the tumor penetrated into duodenal wall. Biopsy from the lymph node in the left supraclavicular fossa indicated diffuse large B-cell lymphoma. Although chemotherapy was planned, massive arterial bleeding occurred from the part of duodenal penetration. Endoscopic hemostasis was unsuccessfully performed. Therefore, we performed transcathether arterial embolization for hemostasis. After the procedure, the patient received six cycles of chemotherapy, and he achieved complete response. He has been alive 5 years without recurrence. There were many cases of gastrointestinal bleeding from primary gastrointestinal lymphomas, while there were few cases with nodal involvement by malignant lymphoma resulting in bleeding from gastrointestinal tract. We herein report a case of duodenal bleeding by nodal involvement of diffuse large B-cell lymphoma with review of literature.

Management of presacral hemorrhage is always challenging. Herein we describe the use of an absorbable hemostatic gauze with α-cyanoacrylate medical adhesive to achieve hemostasis. In this study, we conducted total mesorectal excision for the treatment of rectal cancer in 258 patients from March 2006 to May 2009. Intraoperative presacral hemorrhage developed in 5 (2%) patients during rectal mobilization. In these 5 patients, massive bleeding could not be controlled by pressure and pelvic packing with gauze. An absorbable hemostatic gauze spread with medical adhesive was compressed onto the bleeding vessel for at least 20 minutes. Hemostasis was achieved successfully and was maintained during the surgery. Patients recovered uneventfully and no postoperative events were noted. The use of an absorbable hemostatic gauze with medical adhesive is a simple and effective method for achieving hemostasis when massive presacral hemorrhage occurs. However, its effectiveness needs to be confirmed in a controlled study in a properly selected patient population. Copyright © 2012. Published by Elsevier Inc.

A case study involving a 55-year-old Caucasian male with end-stage glomerulosclerosis is presented here. Kidney biopsies showed no deposits on imunofluorescent microscopy. Relapsing massive haemoptysis and suspected bronchovascular malformation required lung lobectomy which revealed malformative and tortuous small blood vessels, with no vasculitis. Blood antinuclear antibodies, antineutrophil cytoplasmic antibodies and antiglomerular basement membrane antibodies were undetectable. Seric immunoglobulins and complement levels were normal. Three months later, arthralgia and joint oedema first appeared. Skin biopsy revealed vasculitis immune-reactive to immunoglobulin A. Systemic corticotherapy was then started. Two weeks later, the patient presented with abdominal pain melena and rectal bleeding (haematoquesia). Endoscopic study showed diffuse gastrointestinal haemorrhage. Angiographic study revealed diffuse lesions compatible with vasculitis and haemorrhage from multiple spots. Cyclophosphamide and then intravenous immunoglobulin were associated to treatment without response. Increasing blood loss occurred, with massive gastrointestinal haemorrhage and haemorrhagic ascitis. Death occurred due to uncontrolled diffuse bleeding. Necropsy findings showed generalised small vessels vasculitis compatible with Henoch–Schönlein purpura. PMID:22778211

Massive spontaneous hemoperitoneum due to rupture of visceral branches of the abdominal aorta.

Pollak, E W; Michas, C A

Review of 153 cases of massive spontaneous hemoperitoneum following visceral arterial rupture showed that 94% of all young women and 100% of all pregnant women had ruptured congenital splenic artery aneurysms at the time of hemorrhage, whereas young males bled from a variety of sources. Individuals who were 45 years old or older bled either from lesions of the celiac axis or its branches (66%) or from arterial mesenteric system lesions (34%). Only 22% of the older individuals of either sex bled from splenic artery sources. Arterial hypertension was present in 40% and previous or simultaneous intracranial hemorrhage occurred in 9% of the older patients. There were no survivors among those in whom the bleeding source was not operatively controlled. With operation, 79% of the younger patients and 57% of the older ones survived. Results emphasize the high mortality of visceral artery rupture with intraperitoneal bleeding. Prophylactic excision is advised for all complicated aneurysms regardless of age and all uncomplicated aneurysms in healthy individuals, especially in fertile or pregnent women.

Supportive therapy to maintain dental implants is increasingly important. This study examined the effect of a 0.3% triclosan/2% copolymer dentifrice on oral biofilms and gingival inflammation (GI) on dental implants and peri-implant tissues. One hundred and twenty adults with a dental implant and contra-lateral tooth were enrolled in this 6 month, double-blind, two-treatment, parallel group study. Sixty subjects were randomly assigned to a triclosan/copolymer dentifrice test group and 60 subjects to a fluoride dentifrice control group and instructed to brush twice daily for 6 months. At baseline, 3, and 6 months, a calibrated dentist assessed dental plaque, GI and collected supragingival dental plaque for microbiological analysis. Subjects in the triclosan/copolymer group demonstrated significantly lower levels of dental plaque, gingivitis, and bleeding on probing at 3 and 6 months at both the implant and contra-lateral tooth compared with the fluoride group (p<0.05). There were significantly fewer Gram-negative anaerobes in the triclosan/copolymer group (p<0.05) including >90% reductions in Aggregatibacter actinomycetemcomitans, Campylobacter rectus, Eubacterium saburreum, Fusobacterium nucleatum, Porphyromonas gingivalis, Prevotella melaninogenica, Solobacterium moorei, and Tannerella forsythia. Twice daily use of a triclosan/copolymer dentifrice may enhance dental implant maintenance by reducing dental plaque and GI. © 2010 John Wiley & Sons A/S.

The Australian and New Zealand (ANZ) Massive Transfusion (MT) Registry (MTR) has been established to improve the quality of care of patients with critical bleeding (CB) requiring MT (≥ 5 units red blood cells (RBC) over 4 h). The MTR is providing data to: (1) improve the evidence base for transfusion practice by systematically collecting data on transfusion practice and clinical outcomes; (2) monitor variations in practice and provide an opportunity for benchmarking, and feedback on practice/blood product use; (3) inform blood supply planning, inventory management and development of future clinical trials; and (4) measure and enhance translation of evidence into policy and patient blood management guidelines. The MTR commenced in 2011. At each participating site, all eligible patients aged ≥18 years with CB from any clinical context receiving MT are included using a waived consent model. Patient information and clinical coding, transfusion history, and laboratory test results are extracted for each patient's hospital admission at the episode level. Thirty-two hospitals have enrolled and 3566 MT patients have been identified across Australia and New Zealand between 2011 and 2015. The majority of CB contexts are surgical, followed by trauma and gastrointestinal haemorrhage. Validation studies have verified that the definition of MT used in the registry correctly identifies 94 % of CB events, and that the median time of transfusion for the majority of fresh products is the 'product event issue time' from the hospital blood bank plus 20 min. Data linkage between the MTR and mortality databases in Australia and New Zealand will allow comparisons of risk-adjusted mortality estimates across different bleeding contexts, and between countries. Data extracts will be examined to determine if there are differences in patient outcomes according to transfusion practice. The ratios of blood components (e.g. FFP:RBC) used in different types of critical bleeding will also be investigated. The MTR is generating data with the potential to have an impact on management and policy decision-making in CB and MT and provide benchmarking and monitoring tools for immediate application.

The antifibrinolytic agent ε -aminocaproic acid is used to decrease procedural blood loss in a variety of high risk surgeries. The utility of recombinant factor VII administration in massive hemorrhage has also been reported in a variety of settings, though the impact in a surgical context remains unclear. We describe the case of a patient who underwent massive open splenectomy and developed diffuse retroperitoneal bleeding on postoperative day one. Massive transfusion was initiated, but attempts to control hemorrhage with surgical and interventional radiology approaches were unsuccessful, as was recombinant factor VII administration. Commencement of a high dose aminocaproic acid infusion was followed by a prominent rise in fibrinogen levels and stabilization of the hemorrhage. Indications, dosages, and adverse effects of ε -aminocaproic acid as described in the literature are reviewed.

Psychosocial assessment of patients comprises an important element in the selection process of appropriate candidates for left ventricular assist device (LVAD) implantation. We sought to determine the association of the well-validated psychosocial assessment of candidates for transplantation (PACT) scale to clinical outcomes post-LVAD implantation. The PACT scale was used retrospectively to reconstruct psychosocial profiles of all patients who underwent a continuous-flow LVAD implantation for all indications at our institution between March 2008 and August 2012 (N = 230). Psychosocial elements including social support, psychological health, lifestyle factors, comprehension of the operation, and follow-up were evaluated. The primary outcome was overall survival, and the secondary outcomes were hospital readmission, pump thrombosis, hemolysis, gastrointestinal (GI) bleeding, and LVAD driveline infections. The mean age of patients was 55.3 years, with 83% being male; 58% (N = 135) were bridge to transplant and 42% (N = 95) were destination therapy. Up to 1-year post-LVAD implant, there were no statistical differences among the 5 PACT candidate groups in terms of survival ( P = .79), hospital readmissions ( P = .55), suspected or confirmed pump thrombosis ( P = .31), hemolysis ( P = .43), GI bleeding ( P = .71), or driveline infections ( P = .06). In this single-center retrospective review, post hoc reconstruction of psychosocial profiles using the PACT scale and independent assessment of postimplant outcomes, including survival and adverse events, did not show any association. However, given the small number of patients in the low score PACT groups as well as limited duration of follow-up, further studies are required to elucidate the association.

Diverticular bleeding can occasionally cause massive bleeding that requires urgent colonoscopy (CS) and treatment. The aim of this study was to identify significant risk factors for colonic diverticular hemorrhage. Between January 2009 and December 2012, 26,602 patients underwent CS at our institution. One hundred twenty-three patients underwent an urgent CS due to acute lower gastrointestinal hemorrhage. Seventy-two patients were diagnosed with colonic diverticular hemorrhage. One hundred forty-nine age- and sex-matched controls were selected from the patients with nonbleeding diverticula who underwent CS during the same period. The relationship of risk factors to diverticular bleeding was compared between the cases and controls. Uni- and multivariate conditional logistic regression analyses demonstrated that the use of nonsteroidal anti-inflammatory drugs (odds ratio [OR], 14.70; 95% confidence interval [CI], 3.89 to 55.80; p<0.0001), as well as the presence of cerebrovascular disease (OR, 8.66; 95% CI, 2.33 to 32.10; p=0.00126), and hyperuricemia (OR, 15.5; 95% CI, 1.74 to 138.00; p=0.014) remained statistically significant predictors of diverticular bleeding. Nonsteroidal anti-inflammatory drugs, cerebrovascular disease and hyperuricemia were significant risks for colonic diverticular hemorrhage. The knowledge obtained from this study may provide some insight into the diagnostic process for patients with lower gastrointestinal bleeding.

ObjectiveThis retrospective study reports our experience using splenic arterial particle embolization and coil embolization for the treatment of sinistral portal hypertension (SPH) in patients with and without gastric bleeding.MethodsFrom August 2009 to May 2012, 14 patients with SPH due to pancreatic disease were diagnosed and treated with splenic arterial embolization. Two different embolization strategies were applied; either combined distal splenic bed particle embolization and proximal splenic artery coil embolization in the same procedure for acute hemorrhage (1-step) or interval staged distal embolization and proximal embolization in the stable patient (2-step). The patients were clinically followed.ResultsIn 14 patients, splenic arterial embolizationmore » was successful. The one-step method was performed in three patients suffering from massive gastric bleeding, and the bleeding was relieved after embolization. The two-step method was used in 11 patients, who had chronic gastric variceal bleeding or gastric varices only. The gastric varices disappeared in the enhanced CT scan and the patients had no gastric bleeding during follow-up.ConclusionsSplenic arterial embolization, particularly the two-step method, proved feasible and effective for the treatment of SPH patients with gastric varices or gastric variceal bleeding.« less

The kaposiform hemangioendothelioma (KHE) is an uncommon vascular neoplasm of borderline or intermediate malignant potential in which involvement of the head and neck region is rare. A 5-year-old girl was admitted to the emergency room with abrupt massive hemoptysis. Transoral laryngoscopy revealed a round, reddish mass with active bleeding on the anterior portion of the left vocal fold region. Since re-hemoptysis and large amount of aspiration caused breathing difficulties for the patient, suspension exam was performed under general anesthesia. Mass excision and thorough bleeding control was performed with laser assisted laryngo-micro system. Postoperatively, there was no further bleeding. The pathologic diagnosis of the tumor was KHE. To the best of our knowledge, this is the first report of a KHE in the larynx presenting as recurrent hemoptysis in childhood. Copyright (c) 2009 Elsevier Ireland Ltd. All rights reserved.

Intraoperative bleeding control by uniportal video-assisted thoracoscopic surgery†.

Owing to advances in video-assisted thoracic surgery (VATS), the majority of pulmonary resections can currently be performed by VATS in a safe manner with a low level of morbidity and mortality. The majority of the complications that occur during VATS can be minimized with correct preoperative planning of the case as well as careful pulmonary dissection. Coordination of the whole surgical team is essential when confronting an emergency such as major bleeding. This is particularly important during the VATS learning curve, where the occurrence of intraoperative complications, particularly significant bleeding, usually ends in a conversion to open surgery. However, conversion should not be considered as a failure of the VATS approach, but as a resource to maintain the patient's safety. The correct assessment of any bleeding is of paramount importance during major thoracoscopic procedures. Inadequate management of the source of bleeding may result in major vessel injury and massive bleeding. If bleeding occurs, a sponge stick should be readily available to apply pressure immediately to control the haemorrhage. It is always important to remain calm and not to panic. With the bleeding temporarily controlled, a decision must be made promptly as to whether a thoracotomy is needed or if the bleeding can be solved through the VATS approach. This will depend primarily on the surgeon's experience. The operative vision provided with high-definition cameras, specially designed or adapted instruments and the new sealants are factors that facilitate the surgeon's control. After experience has been acquired with conventional or uniportal VATS, the rate of complications diminishes and the majority of bleeding events are controlled without the need for conversion to thoracotomy. © The Author 2015.

Acquired immune deficiency syndrome (AIDS)-related lymphoma (ARL) remains the main cause of AIDS-related deaths in the highly active anti-retroviral therapy (HAART) era. Recently, rearrangement of MYC is associated with poor prognosis in patients with diffuse large B-cell lymphoma. Here, we report a rare case of gastrointestinal (GI)-ARL with MYC rearrangements and coinfected with Epstein-Barr virus (EBV) infection presenting with various endoscopic findings. A 38-year-old homosexual man who presented with anemia and was diagnosed with an human immunodeficiency virus infection for the first time. GI endoscopy revealed multiple dish-like lesions, ulcerations, bloody spots, nodular masses with active bleeding in the stomach, erythematous flat lesions in the duodenum, and multiple nodular masses in the colon and rectum. Magnified endoscopy with narrow band imaging showed a honeycomb-like pattern without irregular microvessels in the dish-like lesions of the stomach. Biopsy specimens from the stomach, duodenum, colon, and rectum revealed diffuse large B-cell lymphoma concomitant with EBV infection that was detected by high tissue EBV-polymerase chain reaction levels and Epstein-Barr virus small RNAs in situ hybridization. Fluorescence in situ hybridization analysis revealed a fusion between the immunoglobulin heavy chain (IgH) and c-MYC genes, but not between the IgH and BCL2 loci. After 1-mo of treatment with HAART and R-CHOP, endoscopic appearance improved remarkably, and the histological features of the biopsy specimens revealed no evidence of lymphoma. However, he died from multiple organ failure on the 139(th) day after diagnosis. The cause of his poor outcome may be related to MYC rearrangement. The GI tract involvement in ARL is rarely reported, and its endoscopic findings are various and may be different from those in non-AIDS GI lymphoma; thus, we also conducted a literature review of GI-ARL cases.

The aim of the present study was to compare the effect of systemically administered lycopene (LycoRed) as a monotherapy and as an adjunct to scaling and root planing in gingivitis patients. Twenty systemically healthy patients showing clinical signs of gingivitis were involved in a randomised, double-blind, parallel, split-mouth study. The subjects were randomly distributed between the two treatment groups: experimental group (n = 10), 8 mg lycopene/day for 2 weeks; and controls (n = 10), placebo for 2 weeks. Quadrant allocation within each group was randomised with two quadrants treated with oral prophylaxis (OP) and two quadrants not receiving any form of treatment (non-OP). Bleeding index (SBI) and non-invasive measures of plaque (PI) and gingivitis (GI) were assessed at baseline, 1 and 2 weeks. Salivary uric acid levels were also measured. All the treatment groups demonstrated statistically significant reductions in the GI, SBI and PI. Treatment with OP-lycopene resulted in a statistically significant decrease in GI when compared with OP-placebo (p < 0.05) and non-OP-placebo (p < 0.01). Treatment with non-OP-lycopene resulted in a statistically significant decrease in GI when compared with non-OP-placebo (p < 0.01). The OP-lycopene group showed a statistically significant reduction in SBI values when compared with the non-OP-lycopene group (p < 0.05) and the non-OP-placebo group (p < 0.001). There was a strong negative correlation between the salivary uric acid levels and the percentage reduction in GI at 1 and 2 weeks in the OP-lycopene group (r = -0.852 and -0.802 respectively) and in the non-OP-lycopene group (r = -0.640 and -0.580 respectively). The results presented in this study suggest that lycopene shows great promise as a treatment modality in gingivitis. The possibility of obtaining an additive effect by combining routine oral prophylaxis with lycopene is also an exciting possibility, which deserves further study.

Plasma products, including fresh frozen plasma, are administered extensively in a variety of settings from massive transfusion to vitamin K antagonist reversal. Despite the widespread use of plasma as a hemostatic agent in bleeding patients, its effect in comparison with other available choices of hemostatic therapies is unclear. We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, PubMed Central, and databases of ongoing trials for randomized controlled trials that assessed the efficacy and/or safety of therapeutic plasma as an intervention to treat bleeding patients compared with other interventions or placebo. Of 1243 unique publications retrieved in our initial search, no randomized controlled trials were identified. Four nonrandomized studies described the effect of therapeutic plasma in bleeding patients; however, data gathered from these studies did not allow for comparison with other therapeutic interventions primarily as a result of the low number of patients and the use of different (or lack of) comparators. We identified two ongoing trials investigating the efficacy and safety of therapeutic plasma, respectively; however, no data have been released as yet. Although plasma is used extensively in the treatment of bleeding patients, evidence from randomized controlled trials comparing its effect with those of other therapeutic interventions is currently lacking.

Identification of a Serratia marcescens virulence factor that promotes hemolymph bleeding in the silkworm, Bombyx mori.

2014-03-01

Injection of culture supernatant of Serratia marcescens, a Gram-negative bacterium pathogenic to a wide range of host animals including insects and mammals, into the hemolymph of silkworm (Bombyx mori) larvae led to continuous flow of the hemolymph (blood of insects) from the injection site. The amount of hemolymph lost within 60 min reached 15-20% of the total larval weight. Using a bioassay with live silkworms, we purified Serralysin, a metalloprotease that requires divalent cations for its activity, as the factor responsible for the promotion of hemolymph bleeding from the culture supernatant of S. marcescens. Recombinant protein also induced hemolymph bleeding in silkworms. Moreover, the culture supernatant of an S. marcescens disruption mutant of the ser gene showed attenuated ability to promote hemolymph bleeding. In addition, this bleeding-promoting activity of the S. marcescens culture supernatant was attenuated by disruption of the wecA gene, which is involved in the biosynthesis of the lipopolysaccharide O-antigen. These findings suggest that Serralysin metalloprotease contributes to the pathogenesis of S. marcescens by inhibiting wound healing, which leads to a massive loss of hemolymph from silkworm larvae.

Spontaneous haemothorax is a subcategory of haemothorax that occurs in the absence of trauma or other causes. It is a rare emergency that can progress rapidly with massive blood loss leading to haemorrhagic shock and death. We describe a patient with massive spontaneous haemothorax caused by the disruption of an oesophageal artery from the middle segment of descending thoracic aorta. We sutured the bleeding artery in an emergency thoracotomy after the failure of interventional procedure. © The Author 2017.

Objective To explore the characters of traditional Chinese medicine (TCM) syndromes after percutaneous coronary intervention (PCI) and to provide syndrome study theoretical evidence for TCM differentiation treatment after PCI through retrospective study. Methods Patients with coronary heart disease (CHD) who underwent PCI in Cardiovascular Intervention Center of Wangjing Hospital during Dec. 2012 to Dec. 2014 and met the inclusion criteria were enrolled. Retrospective study was then conducted based on patients' clinical document and angiography data to explore the distribution pattern of TCM syndromes. Results 801 patients were recruited in the study. TCM syndromes in descending order of their incidence were Qi deficiency and blood stasis syndrome, heart blood stasis syndrome, Qi and Yin deficiency syndrome, phlegm and blood stasis syndrome, Qi stagnation and blood stasis syndrome, Yang asthenia syndrome, heart and kidney yin deficiency syndrome to cold congeal, and blood stasis syndrome in a more to less order. Qi deficiency and blood stasis syndrome was in the most (occurring in 298 patients, 37.20%); Qi and Yin deficiency syndrome occurred in 163 patients (20.35%); heart blood stasis syndrome was shown in 126 patients (15.73%); phlegm and blood stasis syndrome was shown in 95 patients (11.86%). Conclusion Qi deficiency and blood stasis syndrome was closely associated with post-PCI bleeding, implying that this syndrome might serve as a powerful predictor of GI bleeding as well as a potential supplement to the current predicting and scoring system of bleeding such as CRUSADE.

To evaluate the relationship between older adults' medical and oral conditions and their self-reports of periodontal conditions with clinically obtained data. Concerns about oral health of elders and its association with systemic diseases have been gaining more attention. A total of 201 older subjects were interviewed about their previous medical and dental histories and were asked to complete a health questionnaire. Each subject received full mouth exam, including counting number of natural teeth remaining, gingival (GI) and plaque index (PI), CPITN and denture status. Elders who completed health questionnaires had mean age of 62.5. Mean CPITN score was 1.62(± 1.12), PI was 1.57(± 1.48), and GI was 1.55(± 1.31). Women had higher prevalence of CVD and osteoporosis than men (p=0.008, p=0.0001, respectively). Subjects who reported bleeding upon brushing had higher PI and GI scores (p=0.03, p=0.05, respectively). Smokers were more likely to describe their periodontal tissues as unhealthy (72.3% vs. 27.7%, p=0.01), whereas self-reports of healthy vs. unhealthy gums did not differ between non-smokers. These findings suggest that a number of systemic conditions are associated with indicators of periodontal disease, and self-reports of oral conditions are independent of systemic diseases.

[Nonsteroidal Anti-inflammatory Drug and Aspirin-induced Peptic Ulcer Disease].

Despite decreasing Helicobacter pylori prevalence, the prevalence of peptic ulcer disease is increasing in the aged population, mainly due to increasing use of NSAIDs to manage pain and inflammation. In addition, low dose aspirin is employed as an anti-coagulant for those who have suffered or are at high risk of ischemic stroke and cardiovascular disease. However, NSAIDs and aspirin are injurious to mucosa of stomach and duodenum. NSAID-induced inhibition of mucosal prostaglandin synthesis is thought to be a major mechanism of gastrointestinal mucosal injury. The proportion of elderly has increased rapidly in Korea, with the proportion over 65 years old expected to be 24.3% in 2030. In this higher-risk population, the strategy to reduce the incidence of NSAID-related peptic ulcers and complications such as bleeding, obstruction and perforation is very important. Proton pump inhibitors (PPIs) with cyclooxygenase-2 inhibitor can be used for reducing the risk of NSAID-related ulcers and upper gastrointestinal (GI) complications. However, continuous use of PPI has several problems. In addition, NSAID-related problems in the lower GI tract have increased, in contrast to the decrease of NSAID-related upper GI disease. The aim of this review is to provide an evidence-based knowledge regarding the mechanism, complications of treatment, and prevention strategies for NSAID- or aspirin-related peptic ulcer disease in Korea.

Severe periodontitis leading to tooth loss is found in 5-15% of most populations worldwide. The applicability of salivary β -hexosaminidase (β-HEX A%, percentage of β-HEX A isoenzyme to total β-HEX) and β-HEX B% (β-HEX B/β-HEX) indexes was investigated as a possible marker of periodontitis. Thirty three alcohol-dependent smokers (AS) and 32 healthy controls (C) were enrolled in the study. The activity of β-HEX was measured spectrophotometrically. β-HEX A% was significantly higher and β-HEX B% was lower in AS than in C group. We found a significant correlation between β-HEX A% and gingival index (GI) and an inverse correlation between β-HEX A% and salivary flow (SF), in all groups. Salivary β-HEX A% index in smoking alcoholics at 0.23 had excellent sensitivity (96%) and specificity (91%); the AUC for β-HEX A% was high (0.937). There were no correlations between amount/duration-time of alcohol drinking/smoking and β-HEX A% or β-HEX B%. We found significant correlations between the time period of denture wearing and GI, papilla bleeding index (PBI), and decayed missing filled teeth index (DMFT) and between GI and the amount of smoked cigarettes per day. Bad periodontal state was most likely due to the nicotine dependence. Salivary β-HEX A% is a promising excellent marker for the diagnosis of periodontitis.

To assess primary care physician perceptions of non-steroidal anti-inflammatory drug (NSAID) and aspirin-associated toxicity. A group of gastroenterologists and internal medicine physicians created a survey, which was administered via the Internet to a large number of primary care physicians from across the US. One thousand primary care physicians participated. Almost one-third of primary care physicians recommended 325 mg rather than 81 mg of aspirin/day for cardioprotection. Fifty-nine percent thought enteric-coated or buffered aspirin reduced the risk of upper gastrointestinal (GI) bleeding. Seventy-six percent believed that Helicobacter pylori infection increased the risk of NSAID ulcers but fewer than 25% tested NSAID users for this infection. More than two-thirds were aware that aspirin co-therapy decreased the GI safety benefits of the cyclo-oxygenase 2 selective NSAIDs. However, 84% felt that aspirin with a cyclo-oxygenase 2 selective NSAID was safer than aspirin with a non-selective NSAID. When presented a patient at high risk for NSAID-related GI toxicity, almost 50% of primary care physicians recommended a proton pump inhibitor and cyclo-oxygenase 2 selective NSAID. This survey has identified areas of misinformation regarding the risk-benefit of NSAIDs and aspirin and the utilization of gastroprotective strategies. Further education on NSAIDs for primary care physicians is warranted.

Hormones (progesterone and estradiol) change greatly during pregnancy; however, the mechanism of hormonal changes on gingival inflammation is still unclear. This study is to evaluate the effects of hormonal changes during pregnancy on gingival inflammation and interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) in gingival crevicular fluid (GCF). 30 periodontally healthy pregnant women were evaluated in the first, second, and third trimesters. 20 periodontally healthy nonpregnant women were evaluated twice (once per subsequent month). Clinical parameters including probing pocket depth (PPD), bleeding index (BI), gingival index (GI), clinical attachment level (CAL), and plaque index (PLI) were recorded. GCF levels of IL-1β and TNF-α and serum levels of progesterone and estradiol were measured. From the data, despite low PLI, BI and GI increased significantly during pregnancy; however, no significant changes in PLI, CAL, IL-1β, or TNF-α GCF levels were observed. Although IL-1β, not TNF-α, was higher in pregnant group than in nonpregnant group, they showed no correlation with serum hormone levels during pregnancy. GI and BI showed significant positive correlation with serum hormone levels during pregnancy. This study suggests that sex hormone increase during pregnancy might have an effect on inflammatory status of gingiva, independent of IL-1β and TNF-α in GCF. PMID:27034591

To evaluate GI safety of celecoxib compared with 2 nonselective (ns) NSAIDs, as a secondary objective of a large trial examining multiorgan safety. This randomised, double-blind controlled trial analysed 24 081 patients. Osteoarthritis or rheumatoid arthritis patients, needing ongoing NSAID treatment, were randomised to receive celecoxib 100-200 mg b.d., ibuprofen 600-800 mg t.d.s. or naproxen 375-500 mg b.d. plus esomeprazole, and low-dose aspirin or corticosteroids if already prescribed. Clinically significant GI events (CSGIE-bleeding, obstruction, perforation events from stomach downwards or symptomatic ulcers) and iron deficiency anaemia (IDA) were adjudicated blindly. Mean treatment and follow-up durations were 20.3 and 34.1 months. While on treatment or 30 days after, CSGIE occurred in 0.34%, 0.74% and 0.66% taking celecoxib, ibuprofen and naproxen. Hazard ratios (HR) were 0.43 (95% CI 0.27-0.68, P = 0.0003) celecoxib vs ibuprofen and 0.51 (0.32-0.81, P = 0.004) vs naproxen. There was also less IDA on celecoxib: HR 0.43 (0.27-0.68, P = 0.0003) vs ibuprofen; 0.40 (0.25-0.62, P < 0.0001) vs naproxen. Even taken with low-dose aspirin, fewer CSGIE occurred on celecoxib than ibuprofen (HR 0.52 [0.29-0.94], P = 0.03), and less IDA vs naproxen (0.42 [0.23-0.77, P = 0.005]). Corticosteroid use increased total GI events and CSGIE. H. pylori serological status had no influence. Arthritis patients taking NSAIDs plus esomeprazole have infrequent clinically significant gastrointestinal events. Co-prescribed with esomeprazole, celecoxib has better overall GI safety than ibuprofen or naproxen at these doses, despite treatment with low-dose aspirin or corticosteroids. © 2018 John Wiley & Sons Ltd.

The aim of this study was to evaluate the alterations on plaque index (PI), gingival index (GI), gingival bleeding index (GBI), and gingival crevicular fluid (GCF) volume after use of three different brackets types for 60 days. Setting Participants: The sample comprised 20 patients of both sexes aged 11-15 years (mean age: 13.3 years), with permanent dentition, adequate oral hygiene, and mild tooth crowding, overjet, and overbite. A conventional metallic bracket Gemini™, and two different brands of self-ligating brackets - In-Ovation ® R and SmartClip™ - were bonded to the maxillary incisors and canines. PI, GI, GBI scores, and GCF volume were measured before and 30 and 60 days after bonding of the brackets. Data were analysed statistically using non-parametric tests coefficient at a 5% significance level. There was no statistically significant correlation (P > 0.05) between tooth crowding, overjet, and overbite and the PI, GI, GBI scores, and GCF volume before bonding, indicating no influence of malocclusion on the clinical parameters. Regardless of the bracket design, no statistically significant difference (P > 0.05) was found for GI, GBI scores. PI and GCF volume showed a significant difference among the brackets in different periods. In pairwise comparisons a significant difference was observed when compared before with 60 days after bonding, for the teeth bonded with SmartClip™ self-ligating bracket, (PI P = 0.009; GCF volume P = 0.001). There was an increase in PI score and GCF volume 60 days after bonding of SmartClip™ self-ligating brackets, indicating the influence of bracket design on these clinical parameters.

Adverse events related to analgesic use represent a challenge for optimizing treatment of pain in older people. The aim of this study was to determine whether non-selective non-steroidal anti-inflammatory drug (NS-NSAID) and cyclo-oxygenase (COX)-2 inhibitor use is appropriately targeted in those with a prior history of gastrointestinal (GI) events, myocardial infarction (MI) or stroke. A retrospective study of pharmacy claims data from the Australian Government Department of Veterans' Affairs was conducted, involving 288,912 veterans aged 55 years and over. Analgesic utilization from 2007 to 2009 was assessed. Three risk cohorts (veterans with prior hospitalization for GI bleed, MI or stroke) and a low-risk cohort were identified. Poisson regression was applied to test for a linear trend over the study period. The prevalence of analgesics dispensed in the overall study population was approximately 34 % between 2007 and 2009. COX-2 inhibitors were more widely dispensed than NS-NSAIDs in all those at risk of NSAID-related adverse events. At the end of 2009, the ratio was 5.1 % to 2.5 % in the GI cohort, 3.6 % to 3.2 % in the MI cohort and 3.6 % to 2.6 % in the stroke cohort. Although COX-2 inhibitors appeared to be preferred over NS-NSAIDs in those with a prior history of GI events, 2.5 % of patients were still using an NS-NSAID at the end of the study period. Consistent with treatment guidelines, in most of these cases, these drugs were co-dispensed with proton pump inhibitors. COX-2 inhibitors were used at slightly higher rates than NS-NSAIDs in those with a prior history of MI or stroke, which is not consistent with guidelines recommending NS-NSAID use.

Early upper gastrointestinal (UGI) cancer detection had led to organ-preserving endoscopic therapy. Endoscopy is a suitable method of early diagnosis of UGI malignancies. In Iran, exclusion of malignancy is the most important indication for endoscopy. This study is designed to see whether using alarm symptoms can predict the risk of cancer in patients. A total of 3414 patients referred to a tertiary gastrointestinal (GI) clinic in Isfahan, Iran, from 2009 to 2016 with dyspepsia, gastroesophageal reflux disease (GERD), and alarm symptoms, such as weight loss, dysphagia, GI bleeding, vomiting, positive familial history for cancer, and anorexia. Each patient had been underwent UGI endoscopy and patient data, including histology results, had been collected in the computer. We used logistic regression models to estimate the diagnostic accuracy of each alarm symptoms. A total of 3414 patients with alarm symptoms entered in this study, of whom 72 (2.1%) had an UGI malignancy. According to the logistic regression model, dysphagia ( P < 0.001) and weight loss ( P < 0.001) were found to be significant positive predictive factors for malignancy. Furthermore, males were in a significantly higher risk of developing UGI malignancy. Through receiver operating characteristic curve and the area under the curve (AUC) with adequate overall calibration and model fit measures, dysphagia and weight loss as a related cancer predictor had a high diagnostic accuracy (accuracy = 0. 72, AUC = 0. 881). Using a combination of age, alarm symptoms will lead to high positive predictive value for cancer. We recommend to do an early endoscopy for any patient with UGI symptoms and to take multiple biopsies from any rudeness or suspicious lesion, especially for male gender older than 50, dysphagia, or weight loss.

Vascular ectasias, including gastric antral vascular ectasia (GAVE) and angiodysplasia, are increasingly recognized as important sources of gastrointestinal bleeding. This study investigated and compared the efficacies and outcomes of treatment of upper gastrointestinal (UGI) angiodysplasia and GAVE hemorrhage by endoscopic argon plasma coagulation (APC). From January 2006 to December 2009, 46 patients diagnosed with upper GI bleeding caused by angiodysplasia or GAVE at a tertiary hospital were recruited into this study. They included 26 males and 20 females with an average age of 65.6 years (range, 45-90 years). All patients underwent APC for hemostasis during an endoscopic procedure. Parameters such as underlying co-morbidities, number of endoscopic treatment sessions, recurrent bleeding, and clinical outcomes during follow-up were analyzed. The 46 patients with UGI vascular ectasia hemorrhage included 27 patients with angiodysplasia and 19 with GAVE. The patients with angiodysplasia were older than those with GAVE (71.6 ± 10.2 years versus 61.8 ± 11.9 years, P = 0.005). More GAVE patients than angiodysplasia patients had co-existing liver cirrhosis (63.2% versus 25.9%, P = 0.012). The patients with GAVE had a higher rate of recurrent bleeding (78.9% versus 7.4%, P < 0.001) and required more treatment sessions to achieve complete hemostasis (2.4 ± 1.4 versus 1.1 ± 0.1, P < 0.001) than those with angiodysplasia. Univariate analysis demonstrated that age greater than 60 years (odds ratio (OR) = 8.929, P = 0.003), GAVE (OR = 0.021, P < 0.001), and previous radiation therapy (OR = 11.667, P = 0.032) were associated with higher rates of recurrent bleeding. Further multivariate analysis revealed that GAVE was the only independent risk factor for recurrent bleeding after APC treatment (OR = 0.027, P < 0.001). Endoscopic hemostasis with APC is a safe treatment modality for both angiodysplasia and vascular ectasia bleeding. The efficacy of APC treatment is greater for angiodysplasia than for vascular ectasia bleeding. GAVE patients have a higher recurrent bleeding rate and may require multiple treatment sessions for sustained hemostasis.

Postoperative intra-abdominal massive bleeding is a rare and life-threatening complication associated with pancreaticoduodenectomy. Completion pancreatectomy (CP) was usually performed during reexploration for the complication. The management could decrease the complications, such as the pancreatic leakage or intraluminal infection after reexploration, but could increase mortality during the perioperative period. It also could result in loss of pancreatic function forever. This study evaluated an alternative surgical management for intra-abdominal massive hemorrhage to prevent pancreas function, simplify the surgical processes, and decrease the mortality of relaparotomy. Outcome after pancreaticojejunal bridge-anastomosis (PJBA) performed between January 2006 and June 2009 was compared with that after CP performed between February 1984 and December 2005. Between February 1984 and June 2009, 963 patients underwent the Whipple procedure (PD) or pylorus-preserving pancreaticoduodectomy (PPPD). Pancreatic leakage occurred in 103 patients (10.7%); 22 cases (21.4%) developed into intra-abdominal massive bleeding. Nonsurgical procedures of transarterial embolization (TAE) were performed in ten (45.45%) patients, of whom one died (10%). Twelve (54.55%) underwent reoperation. Five had CP with one death (20%). Pancreatic remnant was preserved by pancreaticojejunal bridge-anastomosis (PJBA) in seven patients with no deaths. The reexploration time was 340 +/- 48.2 min vs. 247.9 +/- 40.8 min (P < 0.01) for CP and PJBA group and the blood loss was 2,180 +/- 526.3 ml vs. 1,628.6 +/- 325.1 ml (P < 0.05). In-hospital time for CP was less than that for PJBA (P < 0.05). All patients with CP still developed endocrine insufficiency ("brittle" diabetes) and diarrhea (exocrine insufficiency). There were no evidences of exocrine and endocrine insufficiency in patients with PJBA. Pancreaticojejunal bridge-anastomosis is an easy, simple, and safe procedure for intra-abdominal massive hemorrhage associated with pancreaticoduodenectomy. It could decrease the mortality of reoperation and preserve the pancreatic function.

Since intentional overdose with rivaroxaban is expected to lead to significant coagulopathy and bleeding, prophylactic reversal has been suggested. We report a single massive ingestion confirmed by a blood concentration that was managed with expectant therapy alone. A 71-year-old man with atrial fibrillation, aortic valve replacement, and congestive heart failure presented to the emergency department after an intentional ingestion of 97 (1940 mg total) rivaroxaban tablets in a suicide attempt. Initial laboratories revealed: PT, 60.2 s; INR 7.2; aPTT, 55.7 s; BUN 28 mg/dL; and creatinine 1.2 mg/dL. A whole-blood rivaroxaban concentration obtained on hospital-day three was 160 ng/mL. The patient was admitted for continued observation and the coagulation markers trended downward with no major bleeding events. No reversal agents or blood products were given during his hospitalization. In the setting of a single, acute rivaroxaban overdose, with normal renal function, and no active bleeding, conservative therapy alone may be sufficient.

Acute gastrointestinal bleeding-massive acute bleeding from gastrointestinal section is one of the most frequent forms of acute abdomen. The mortality degree in emergency surgery is about 10%. It's very difficult to identify the place of bleeding and etiology. The important purpose of this research is to present the cases of acute gastrointestinal bleeding from the patients which were monitored and treated at The University Clinical Center of Kosova-Emergency Center in Pristina. These inquests included 137 patients with acute gastrointestinal bleeding who were treated in emergency center of The University Clinical Center in Pristina for the period from January 2005 until December 2006. From 137 patients with acute gastrointestinal bleeding 41% or 29% was female and 96% or 70.1% male. Following the sex we gained a high significant difference of statistics (p < 0.01). The gastrointestinal bleeding was two times more frequent in male than in female. Also in the age-group we had a high significant difference of statistics (p < 0.01) 63.5% of patients were over 55 years old. The mean age of patients with an acute gastrointestinal bleeding was 58.4 years SD 15.8 age. The mean age for female patients was 56.4 age SD 18.5 age. The patients with arterial systolic pressure under 100 mmHg have been classified as patients with hypovolemic shock. They participate with 17.5% in all prevalence of acute gastrointestinal bleeding. From the number of prevalence 2 {1.5%} patients have been diagnosed with peptic ulcer, 1 {0.7%} as gastric perforation and 1 {0.7%} with intestine ischemia. Abdominal Surgery and Intensive Care 2 or 1.5% died, 1 at intensive care unit and 1 at nephrology. As we know the severe condition of the patients with gastrointestinal bleeding and etiology it is very difficult to establish, we need to improve for the better conditions in our emergency center for treatment and initiation base of clinic criteria.

The effects of radiotherapy are debated in inflammatory bowel disease (IBD). We examined IBD patients with colorectal cancer (CRC) and compared those who underwent external beam radiation therapy (EBRT) to those who did not. We then compared those same patients treated with EBRT to similarly treated non-IBD patients to ascertain differences in toxicity and perioperative outcomes. Fifty-seven IBD patients with CRC received EBRT, of which 23 had perioperative follow-up and 15 had complete records. The 23 patients were compared to 229 IBD patients with CRC who did not receive EBRT. The 15 patients were matched, 1:2, to similarly treated non-IBD patients with CRC based on age (±5 years), treatment year (±1 year), BMI (±10 kg/m2), and clinical stage. There was significantly more postoperative bleeding (5.3 % vs. 0 %, p < 0.01), wound dehiscence (3.5 % vs. 0 %, p < 0.01), and perineal infection (8.8 % vs. 1.3 %, p < 0.01) in IBD patients with EBRT compared to those without EBRT. IBD patients were significantly more likely to have grade 3 or higher lower GI toxicity (40 % vs. 7 %, p = 0.02) and wound dehiscence (36 % vs. 7 %, p = 0.02) than non-IBD patients, however without significant difference in bleeding, infection, ileus, or survival. IBD patients with CRC who received EBRT were more likely than similar patients without EBRT to experience perioperative complications. These patients also experienced more lower GI toxicity than similarly treated non-IBD patients with CRC. The expected decrease in survival in IBD-associated CRC was not observed. Thus, EBRT may contribute to a survival benefit in this group.

Helicobacter pylori and non-steroidal anti-inflammatory drugs: does infection affect the outcome of NSAID therapy?

PubMed Central

McCarthy, D. M.

1998-01-01

1. H. pylori gastritis appears to increase the likelihood of developing dyspeptic symptoms on NSAID therapy. 2. There is preliminary evidence that the histologic severity of H. pylori gastritis may be adversely affected by NSAID therapy, with a consequent increase in the risk of developing a peptic ulcer, possibly with complications. Whether this results from an effect on the inflammatory process or results from a quantitative increase in H. pylori colonization is unknown. In these respects, ASA may differ from other NSAIDs. 3. Ulcers are more likely to develop during the course of NSAID therapy in those infected with H. pylori; eradication of the infection reduces ulcer recurrence in the face of continued NSAID therapy, and it seems likely that this must reduce but not abolish the risk of GI bleeding in those using NSAIDs. Eradication also reduces the damage (and possibly risks) of low-dose aspirin therapy. 4. While H. pylori and NSAID use are independent risk factors for GI bleeding, whether or not they are interactive remains unresolved. 5. The effect of H. pylori infection on the risk of perforation during NSAID therapy, or conversely, the contribution of NSAID therapy to the risk of perforation in H. pylori-infected subjects, is also unclear at the present time. 6. Only large outcome studies of accurately diagnosed patients (with regard to H. pylori gastritis), and with much more specific detail as to the type of NSAID, dose and duration of therapy, employing only well-defined end-points, such as significant hemorrhage, perforation or death, and avoiding all surrogate markers short of these end points can hope to unravel this tangled web.

The objective of this study was to evaluate the safety and efficacy of a novel 5-mm laparoscopic linear stapler in clinical gastrointestinal surgical applications. A prospective, single-arm study with an open enrollment of subjects requiring stapling of the gastrointestinal (GI) tract was performed. The study endpoints were the number of complications and technical failures associated with the use of a novel stapler when compared to similar events with conventional staplers as described in the medical literature. Seven centers enrolled 160 subjects, 150 of which were followed up to at least 30 days postoperatively. Intraoperative success: In 423 deployments, there were two staple line leaks and five staple line bleeds, all of which were intraoperatively resolved. In addition, incomplete staple lines were noted as a result of user error (n = 15) or device-related issues (n = 22), all of which were immediately resolved and none of which resulted in a complication or a change of the surgical procedure. Late outcomes: A total of 13 surgical complications in 160 patients were related to a GI transection or anastomosis, 12 of which related to a hand-sewn anastomosis or use of other commercially available staplers. One event (1/153, 0.065 %) on POD 1, involving bleeding of the staple line, was felt to be related to the use of the new stapler. The study confirmed that the new device was user-friendly (9 % incidence of problems firing the device), reliable (3 % device failures) and safe (<1 % complication rate related to the stapler). Based on these results, it would seem that this new 5-mm stapler is a safe and effective alternative to standard 12-mm staplers.

We previously derived and validated the AIMS65 score, a mortality prognostic scale for upper GI bleeding (UGIB). To validate the AIMS65 score in a different patient population and compare it with the Glasgow-Blatchford risk score (GBRS). Retrospective cohort study. Adults with a primary diagnosis of UGIB. inpatient mortality. composite clinical endpoint of inpatient mortality, rebleeding, and endoscopic, radiologic or surgical intervention; blood transfusion; intensive care unit admission; rebleeding; length of stay; timing of endoscopy. The area under the receiver-operating characteristic curve (AUROC) was calculated for each score. Of the 278 study patients, 6.5% died and 35% experienced the composite clinical endpoint. The AIMS65 score was superior in predicting inpatient mortality (AUROC, 0.93 vs 0.68; P < .001), whereas the GBRS was superior in predicting blood transfusions (AUROC, 0.85 vs 0.65; P < .01) The 2 scores were similar in predicting the composite clinical endpoint (AUROC, 0.62 vs 0.68; P = .13) as well as the secondary outcomes. A GBRS of 10 and 12 or more maximized the sum of the sensitivity and specificity for inpatient mortality and rebleeding, respectively. The cutoff was 2 or more for the AIMS65 score for both outcomes. Retrospective, single-center study. The AIMS65 score is superior to the GBRS in predicting inpatient mortality from UGIB, whereas the GBRS is superior for predicting blood transfusion. Both scores are similar in predicting the composite clinical endpoint and other outcomes in clinical care and resource use. Copyright © 2013 American Society for Gastrointestinal Endoscopy.

Prophylactic endotracheal intubation (PEI) is often advocated to mitigate the risk of cardiopulmonary adverse events in patients presenting with brisk upper GI bleeding (UGIB). However, the benefit of such a measure remains controversial. Our study aimed to compare the incidence of cardiopulmonary unplanned events between critically ill patients with brisk UGIB who underwent endotracheal intubation versus those who did not. Patients aged 18 years or older who presented at Cleveland Clinic between 2011 and 2014 with hematemesis and/or patients with melena with consequential hypovolemic shock were included. The primary outcome was a composite of several cardiopulmonary unplanned events (pneumonia, pulmonary edema, acute respiratory distress syndrome, persistent shock/hypotension after the procedure, arrhythmia, myocardial infarction, and cardiac arrest) occurring within 48 hours of the endoscopic procedure. Propensity score matching was used to match each patient 1:1 in variables that could influence the decision to intubate. These included Glasgow Blatchford Score, Charleston Comorbidity Index, and Acute Physiology and Chronic Health Evaluation scores. Two hundred patients were included in the final analysis. The baseline characteristics, comorbidity scores, and prognostic scores were similar between the 2 groups. The overall cardiopulmonary unplanned event rates were significantly higher in the intubated group compared with the nonintubated group (20% vs 6%, P = .008), which remained significant (P = .012) after adjusting for the presence of esophageal varices. PEI before an EGD for brisk UGIB in critically ill patients is associated with an increased risk of unplanned cardiopulmonary events. The benefits and risks of intubation should be carefully weighed when considering airway protection before an EGD in this group of patients.

Objectives: The antiplaque and antigingivitis effect of Lippia Sidoides (LS) was evaluated in this in vivo investigation. Material and Methods: Twenty-three subjects participated in a cross-over, double-blind clinical study, using 21-day partial-mouth experimental model of gingivitis. A toothshield was constructed for each volunteer, avoiding the brushing of the 4 experimental posterior teeth in the lower left quadrant. The subjects were randomly assigned initially to use either the placebo gel (control group) or the test gel, containing 10% LS (test group). Results: The clinical results showed statistically significant differences for plaque index (PLI) (p<0.01) between days 0 and 21 in both groups, however only the control group showed statistically significant difference (p<0.01) for the bleeding (IB) and gingival (GI) index within the experimental period of 21 days. On day 21, the test group presented significantly better results than the control group with regard to the GI (p<0.05). Conclusions: The test gel containing 10% LS was effective in the control of gingivitis. PMID:19936516

Objective: This study compared the effect of 980 Diode laser + scaling and root planing (SRP) versus SRP alone in the treatment of chronic periodontitis. Method: 21 healthy patients with moderate periodontitis with a probing depth of at least 5mm were included in the study. A total of 42 sites were treated during 6weeks with a combination of 980 Diode laser and SRP (21 sites) or SRP alone (21 sites). The gingival index (GI), probing pocket depth (PPD) and bleeding on probing (BOP) were examined at the baseline and after 6 weeks after the start of treatment. Results: Both groups showed statistically significant improvements in GI, BOP and PPD after treatment. The results also showed significant improvement from laser+ SRP group to SRP alone group. Conclusion: The present data suggest that treatment of chronic periodontitis with either 980 Diode laser + SRP or SRP alone results in statistically significant improvements in the clinical parameters. The combination of 980 Diode laser irradiation in the gingival sulcus and SRP, was significantly better as compared to SRP alone.

This observational, retrospective cohort study assessed outcomes of the current management strategies for nonvariceal upper gastrointestinal bleeding in several European countries (Belgium, Greece, Italy, Norway, Portugal, Spain, and Turkey) (NCT00797641; ENERGIB). Turkey contributed 23 sites to this study. Adult patients (≥18 years old) consecutively admitted to hospital and who underwent endoscopy for overt non-variceal upper gastrointestinal bleeding (hematemesis, melena or hematochezia, with other clinical/laboratory evidence of acute upper GI blood loss) were included in the study. Data were collected from patient medical records regarding bleeding continuation, re-bleeding, pharmacological treatment, surgery, and mortality during a 30-day follow-up period. A total of 423 patients (67.4% men; mean age: 57.8 ± 18.9 years) were enrolled in the Turkish study centers, of whom 96.2% were admitted to hospital with acute non-variceal upper gastrointestinal bleeding. At admission, the most common symptom was melena (76.1%); 28.6% of patients were taking aspirin, 19.9% were on non-steroidal anti-inflammatory drugs, and 7.3% were on proton pump inhibitors. The most common diagnoses were duodenal (45.2%) and gastric (27.7%) ulcers and gastritis/gastric erosions (26.2%). Patients were most often managed in general medical wards (45.4%). A gastrointestinal team was in charge of treatment in 64.8% of cases. Therapeutic procedures were performed in 32.4% of patients during endoscopy. After the endoscopy, most patients (94.6%) received proton pump inhibitors. Mean (SD) hospital stay was 5.36 ± 4.91 days. The cumulative proportions of continued bleeding/re-bleeding, complications and mortality within 30 days of the non-variceal upper gastrointestinal bleeding episode were 9.0%, 5.7% and 2.8%, respectively. In the Turkish sub-group of patients, the significant risk factors for bleeding continuation or re-bleeding were age >65 years, presentation with hematemesis or shock/syncope, and the diagnosis of duodenal ulcer. The risk of clinical complications after non-variceal upper gastrointestinal bleeding was higher in female patients older than 65 years, in patients with comorbidities, and in patients presenting with shock/syncope, and also according to time to endoscopy. The use of aspirin, non-steroidal anti-inflammatory drugs or warfarin at baseline was negatively associated with the development of bleeding or clinical complications. The risk of death within 30 days after non-variceal upper gastrointestinal bleeding was significantly higher in patients older than 65 years and in those receiving transfusions other than intravenous fluid or red blood cells within 12 hours of presentation. According to the survey results, non-variceal upper gastrointestinal bleeding in Turkey varies from that in other European countries in a number of aspects. These differences could be associated with a younger population and Helicobacter pylori incidence. Despite the diminishing need for surgical intervention and mortality rates for non-variceal upper gastrointestinal bleeding, as is the case in other European countries, non-variceal upper gastrointestinal bleeding remains a serious problem.

A 22-year old man presented with a massive haemothorax 25 days after bullectomy for a spontaneous pneumothorax. Thoracoscopic surgery revealed ongoing bleeding from the chest wall caused by a sharp edge of the Endoloop Ligature (Ethicon Endo-Surgery) used to resect the remaining small part of the lung at the earlier staple bullectomy. The point where bleeding was occurring was clipped and covered using a collagen patch coated with human fibrinogen and thrombin. The protruding sharp edge of the Endoloop was excised together with the surrounding lung tissue, using a stapler. Although prevention of this type of complication is difficult, awareness of the potential problem may help in managing such extremely rare events.

Piroxicam-β-Cyclodextrin: A GI Safer Piroxicam

PubMed Central

Scarpignato, C

2013-01-01

Although NSAIDs are very effective drugs, their use is associated with a broad spectrum of adverse reactions in the liver, kidney, cardiovascular (CV) system, skin and gut. Gastrointestinal (GI) side effects are the most common and constitute a wide clinical spectrum ranging from dyspepsia, heartburn and abdominal discomfort to more serious events such as peptic ulcer with life-threatening complications of bleeding and perforation. The appreciation that CV risk is also increased further complicates the choices of physicians prescribing anti-inflammatory therapy. Despite prevention strategies should be implemented in patients at risk, gastroprotection is often underused and adherence to treatment is generally poor. A more appealing approach would be therefore to develop drugs that are devoid of or have reduced GI toxicity. Gastro-duodenal mucosa possesses many defensive mechanisms and NSAIDs have a deleterious effect on most of them. This results in a mucosa less able to cope with even a reduced acid load. NSAIDs cause gastro-duodenal damage, by two main mechanisms: a physiochemical disruption of the gastric mucosal barrier and systemic inhibition of gastric mucosal protection, through inhibition of cyclooxygenase (COX, PG endoperoxide G/H synthase) activity of the GI mucosa. However, against a background of COX inhibition by anti-inflammatory doses of NSAIDs, their physicochemical properties, in particular their acidity, underlie the topical effect leading to short-term damage. It has been shown that esterification of acidic NSAIDs suppresses their gastrotoxicity without adversely affecting anti-inflammatory activity. Another way to develop NSAIDs with better GI tolerability is to complex these molecules with cyclodextrins (CDs), giving rise to so-called “inclusion complexes” that can have physical, chemical and biological properties very different from either those of the drug or the cyclodextrin. Complexation of NSAIDs with β-cyclodextrin potentially leads to a more rapid onset of action after oral administration and improved GI tolerability because of minimization of the drug gastric effects. One such drug, piroxicam-β-cyclodextrin (PBC), has been used in Europe for 25 years. Preclinical and clinical pharmacology of PBC do show that the β-cyclodextrin inclusion complex of piroxicam is better tolerated from the upper GI tract than free piroxicam, while retaining all the analgesic and anti-inflammatory properties of the parent compound. In addition, the drug is endowed with a quick absorption rate, which translates into a faster onset of analgesic activity, an effect confirmed in several clinical studies. An analysis of the available trials show that PBC has a GI safety profile, which is better than that displayed by uncomplexed piroxicam. Being an inclusion complex of piroxicam, whose CV safety has been pointed out by several observational studies, PBC should be viewed as a CV safe anti-inflmmatory compound and a GI safer alternative to piroxicam. As a consequence, it should be considered as a useful addition to our therapeutic armamentarium. PMID:23394552

Purpose: To analyze the cause of GI symptoms after pelvic radiotherapy (RT) in a consecutive series of patients with symptoms beginning after RT. A striking lack of evidence is available concerning the optimal treatment for the 50% of patients who develop permanent changes in bowel habits affecting their quality of life after pelvic RT. As a result, in the UK, most such patients are never referred to a gastroenterologist. Methods and Materials: All diagnoses were prospectively recorded from a consecutive series of patients with symptoms that started after RT and who were referred during a 32-month period to a gastroenterologymore » clinic. Patients either underwent direct access flexible sigmoidoscopy or were investigated in a standard manner by one gastroenterologist after first being seen in the clinic. Results: A total of 265 patients referred from 15 institutions were investigated. They included 90 women (median age, 61.5 years; range, 22-84 years) and 175 men (median age, 70 years; range, 31-85 years). RT had been completed a median of 3 years (range, 0.1-34 years) before the study in the women and 2 years (range, 0-21 years) before in the men. Of the 265 patients, 171 had primary urologic, 78 gynecologic, and 16 GI tumors. The GI symptoms included rectal bleeding in 171, urgency in 82, frequency in 80, tenesmus, discomfort, or pain in 79, fecal incontinence in 79, change in bowel habit in 42, weight loss in 19, vomiting without other obstructive symptoms in 18, steatorrhea in 7, nocturnal defecation in 8, obstructive symptoms in 4, and other in 24. After investigation, significant neoplasia was found in 12%. One-third of all diagnoses were unrelated to the previous RT. More than one-half of the patients had at least two diagnoses. Many of the abnormalities diagnosed were readily treatable. The symptoms were generally unhelpful in predicting the diagnosis, with the exception of pain, which was associated with neoplasia (p < 0.001). Conclusion: The results of our study have shown that radiation enteritis is not a single disease entity. More than one-half of the patients had more than one GI diagnosis contributing to their symptoms. After pelvic RT, specific GI symptoms were not a reliable measure of the underlying diagnoses, and the evaluation of new GI symptoms is worthwhile. An algorithm for this purpose is proposed.« less

Background. Severe periodontitis leading to tooth loss is found in 5–15% of most populations worldwide. Aim. The applicability of salivary β-hexosaminidase (β-HEX A%, percentage of β-HEX A isoenzyme to total β-HEX) and β-HEX B% (β-HEX B/β-HEX) indexes was investigated as a possible marker of periodontitis. Methods. Thirty three alcohol-dependent smokers (AS) and 32 healthy controls (C) were enrolled in the study. The activity of β-HEX was measured spectrophotometrically. Results. β-HEX A% was significantly higher and β-HEX B% was lower in AS than in C group. We found a significant correlation between β-HEX A% and gingival index (GI) and an inverse correlation between β-HEX A% and salivary flow (SF), in all groups. Salivary β-HEX A% index in smoking alcoholics at 0.23 had excellent sensitivity (96%) and specificity (91%); the AUC for β-HEX A% was high (0.937). There were no correlations between amount/duration-time of alcohol drinking/smoking and β-HEX A% or β-HEX B%. We found significant correlations between the time period of denture wearing and GI, papilla bleeding index (PBI), and decayed missing filled teeth index (DMFT) and between GI and the amount of smoked cigarettes per day. Conclusion. Bad periodontal state was most likely due to the nicotine dependence. Salivary β-HEX A% is a promising excellent marker for the diagnosis of periodontitis. PMID:24288426

GUCY2C Signaling Opposes the Acute Radiation-Induced GI Syndrome.

High doses of ionizing radiation induce acute damage to epithelial cells of the gastrointestinal (GI) tract, mediating toxicities restricting the therapeutic efficacy of radiation in cancer and morbidity and mortality in nuclear disasters. No approved prophylaxis or therapy exists for these toxicities, in part reflecting an incomplete understanding of mechanisms contributing to the acute radiation-induced GI syndrome (RIGS). Guanylate cyclase C (GUCY2C) and its hormones guanylin and uroguanylin have recently emerged as one paracrine axis defending intestinal mucosal integrity against mutational, chemical, and inflammatory injury. Here, we reveal a role for the GUCY2C paracrine axis in compensatory mechanisms opposing RIGS. Eliminating GUCY2C signaling exacerbated RIGS, amplifying radiation-induced mortality, weight loss, mucosal bleeding, debilitation, and intestinal dysfunction. Durable expression of GUCY2C, guanylin, and uroguanylin mRNA and protein by intestinal epithelial cells was preserved following lethal irradiation inducing RIGS. Oral delivery of the heat-stable enterotoxin (ST), an exogenous GUCY2C ligand, opposed RIGS, a process requiring p53 activation mediated by dissociation from MDM2. In turn, p53 activation prevented cell death by selectively limiting mitotic catastrophe, but not apoptosis. These studies reveal a role for the GUCY2C paracrine hormone axis as a novel compensatory mechanism opposing RIGS, and they highlight the potential of oral GUCY2C agonists (Linzess; Trulance) to prevent and treat RIGS in cancer therapy and nuclear disasters.

Halperin-Sternfeld, Michal; Zigdon-Giladi, Hadar; Machtei, Eli E

2016-03-01

The aim of this study was to retrospectively evaluate the association between shallow vestibular depth (VD) and peri-implant parameters. Peri-implant parameters were evaluated in 61 periodontal patients under regular supportive periodontal therapy. Clinical parameters included gingival index (GI), plaque index (PI), bleeding on probing (BOP), peri-implant pocket depths (PPD), mucosal recession (MR), relative attachment level (RAL), width and thickness of keratinized mucosa (KMW, KMT) and VD. Radiographic bone level (RBL) was measured on peri-apical radiographs. Sites with shallow VD (≤ 4 mm) were associated with higher MR (0.91 mm versus 0.47 mm, p ≤ 0.009), higher RAL (4.23 mm versus 3.59 mm, p ≤ 0.0001) and higher RBL (2.18 mm versus 1.7 mm, p = 0.05) when compared with adequate vestibular depth sites (VD > 4 mm). Moreover, sites with shallow VD presented lower KMW compared with sites with adequate VD (1.24 mm versus 2.38 mm, respectively, p ≤ 0.0001). Slightly greater BOP, and GI were recorded for the shallow VD compared with adequate sites. According to multivariate analysis, factors that could predict RAL included: VD, GI, age, supporting periodontal therapy, implant type and design. Based on this study, inadequate vestibular depth around dental implants may be associated with increased peri-implant bone loss and mucosal recession. Further prospective and intervention studies will be required to fully understand this phenomenon. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Massive transfusion: an overview of the main characteristics and potential risks associated with substances used for correction of a coagulopathy.

PubMed

Seghatchian, Jerard; Samama, Meyer Michel

2012-10-01

Massive transfusion (MT) is an empiric mode of treatment advocated for uncontrolled bleeding and massive haemorrhage, aiming at optimal resuscitation and aggressive correction of coagulopathy. Conventional guidelines recommend early administration of crystalloids and colloids in conjunction with red cells, where the red cell also plays a critical haemostatic function. Plasma and platelets are only used in patients with microvascular bleeding with PT/APTT values >1.5 times the normal values and if PLT counts are below 50×10(9)/L. Massive transfusion carries a significant mortality rate (40%), which increases with the number of volume expanders and blood components transfused. Controversies still exist over the optimal ratio of blood components with respect to overall clinical outcomes and collateral damage. While inadequate transfusion is believed to be associated with poor outcomes but empirical over transfusion results in unnecessary donor exposure with an increased rate of sepsis, transfusion overload and infusion of variable amounts of some biological response modifiers (BRMs), which have the potential to cause additional harm. Alternative strategies, such as early use of tranexamic acid are helpful. However in trauma settings the use of warm fresh whole blood (WFWB) instead of reconstituted components with a different ratio of stored components might be the most cost effective and safer option to improve the patient's survival rate and minimise collateral damage. This manuscript, after a brief summary of standard medical intervention in massive transfusion focuses on the main characteristics of various substances currently available to overcome massive transfusion coagulopathy. The relative levels of some BRMs in fresh and aged blood components of the same origin are highlighted and some myths and unresolved issues related to massive transfusion practice are discussed. In brief, the coagulopathy in MT is a complex phenomenon, often complicated by chronic activation of coagulation, platelets, complement and vascular endothelial cells, where haemolysis, microvesiculation, exposure of phosphatidyl serine positive cells, altered red cells with reduced adhesive proteins and the presence of some BRM, could play a pivotal role in the coagulopathy and untoward effects. The challenges of improving the safety of massive transfusion remain as numerous and as varied as ever. The answer may reside in appropriate studies on designer whole blood, combined with new innovative tools to diagnosis a coagulopathy and an evidence based mode of therapy to establish the optimal survival benefit of patients, always taking into account the concept of harm reduction and reduction of collateral damage.

Guidelines for the management of iron deficiency anaemia.

PubMed

Goddard, Andrew F; James, Martin W; McIntyre, Alistair S; Scott, Brian B

2011-10-01

Iron deficiency anaemia (IDA) occurs in 2-5% of adult men and postmenopausal women in the developed world and is a common cause of referral to gastroenterologists. Gastrointestinal (GI) blood loss from colonic cancer or gastric cancer, and malabsorption in coeliac disease are the most important causes that need to be sought. DEFINING IRON DEFICIENCY ANAEMIA: The lower limit of the normal range for the laboratory performing the test should be used to define anaemia (B). Any level of anaemia should be investigated in the presence of iron deficiency (B). The lower the haemoglobin the more likely there is to be serious underlying pathology and the more urgent is the need for investigation (B). Red cell indices provide a sensitive indication of iron deficiency in the absence of chronic disease or haemoglobinopathy (A). Haemoglobin electrophoresis is recommended when microcytosis and hypochromia are present in patients of appropriate ethnic background to prevent unnecessary GI investigation (C). Serum ferritin is the most powerful test for iron deficiency (A). Upper and lower GI investigations should be considered in all postmenopausal female and all male patients where IDA has been confirmed unless there is a history of significant overt non-GI blood loss (A). All patients should be screened for coeliac disease (B). If oesophagogastroduodenoscopy (OGD) is performed as the initial GI investigation, only the presence of advanced gastric cancer or coeliac disease should deter lower GI investigation (B). In patients aged >50 or with marked anaemia or a significant family history of colorectal carcinoma, lower GI investigation should still be considered even if coeliac disease is found (B). Colonoscopy has advantages over CT colography for investigation of the lower GI tract in IDA, but either is acceptable (B). Either is preferable to barium enema, which is useful if they are not available. Further direct visualisation of the small bowel is not necessary unless there are symptoms suggestive of small bowel disease, or if the haemoglobin cannot be restored or maintained with iron therapy (B). In patients with recurrent IDA and normal OGD and colonoscopy results, Helicobacter pylori should be eradicated if present. (C). Faecal occult blood testing is of no benefit in the investigation of IDA (B). All premenopausal women with IDA should be screened for coeliac disease, but other upper and lower GI investigation should be reserved for those aged 50 years or older, those with symptoms suggesting gastrointestinal disease, and those with a strong family history of colorectal cancer (B). Upper and lower GI investigation of IDA in post-gastrectomy patients is recommended in those over 50 years of age (B). In patients with iron deficiency without anaemia, endoscopic investigation rarely detects malignancy. Such investigation should be considered in patients aged >50 after discussing the risk and potential benefit with them (C). Only postmenopausal women and men aged >50 years should have GI investigation of iron deficiency without anaemia (C). Rectal examination is seldom contributory, and, in the absence of symptoms such as rectal bleeding and tenesmus, may be postponed until colonoscopy. Urine testing for blood is important in the examination of patients with IDA (B). All patients should have iron supplementation both to correct anaemia and replenish body stores (B). Parenteral iron can be used when oral preparations are not tolerated (C). Blood transfusions should be reserved for patients with or at risk of cardiovascular instability due to the degree of their anaemia (C).

A Phase II Study of Bevacizumab in Combination With Definitive Radiotherapy and Cisplatin Chemotherapy in Untreated Patients With Locally Advanced Cervical Carcinoma: Preliminary Results of RTOG 0417

Schefter, Tracey E., E-mail: tracey.schefter@ucdenver.edu; Winter, Kathryn; Kwon, Janice S.

Purpose: Concurrent cisplatin-based chemoradiotherapy (CRT) is the standard treatment for locally advanced cervical cancer. RTOG 0417 was a Phase II study exploring the safety and efficacy of the addition of bevacizumab to standard CRT. Methods and Materials: Eligible patients with bulky tumors (Stage IB-IIIB) were treated with once-weekly cisplatin (40 mg/m{sup 2}) chemotherapy and standard pelvic radiotherapy and brachytherapy. Bevacizumab was administered at 10 mg/kg intravenously every 2 weeks for three cycles. Treatment-related serious adverse event (SAE) and other adverse event (AE) rates within the first 90 days from treatment start were determined. Treatment-related SAEs were defined as any Grademore » {>=}4 vaginal bleeding or thrombotic event or Grade {>=}3 arterial event, gastrointestinal (GI) bleeding, or bowel/bladder perforation, or any Grade 5 treatment-related death. Treatment-related AEs included all SAEs and Grade 3 or 4 GI toxicity persisting for >2 weeks despite medical intervention, Grade 4 neutropenia or leukopenia persisting for >7 days, febrile neutropenia, Grade 3 or 4 other hematologic toxicity, and Grade 3 or 4 GI, renal, cardiac, pulmonary, hepatic, or neurologic AEs. All AEs were scored using the National Cancer Institute Common Terminology Criteria (CTCAE) v 3.0 (MedDRA version 6.0). Results: A total of 60 patients from 28 institutions were enrolled between 2006 and 2009, and of these, 49 patients were evaluable. The median follow-up was 12.4 months (range, 4.6-31.4 months).The median age was 45 years (range, 22-80 years). Most patients had FIGO Stage IIB (63%) and were of Zubrod performance status of 0 (67%). 80% of cases were squamous. There were no treatment-related SAEs. There were 15 (31%) protocol-specified treatment-related AEs within 90 days of treatment start; the most common were hematologic (12/15; 80%). 18 (37%) occurred during treatment or follow-up at any time. 37 of the 49 patients (76%) had cisplatin and bevacizumab administered per protocol, and 46 of the 49 (94%) had both external beam and brachytherapy administered per protocol or with acceptable variation. Conclusion: Bevacizumab in addition to standard pelvic chemoradiotherapy for locally advanced cervical cancer is feasible and safe with respect to the protocol-specified treatment-related SAEs and AEs.« less

Benign GI strictures occur typically in the esophagus and pyloric channel but can occur anywhere in the GI tract and at anastomotic sites. Such strictures can be treated with dilation, incisional therapy, steroid injection, and stents. Our aim was to describe the use of a lumen-apposing metal stent (LAMS) to treat short, benign GI strictures. Consecutive patients who underwent LAMS placement for various benign strictures at 2 tertiary care centers from August 2014 to November 2015 were reviewed retrospectively. The main outcome measures were technical success, clinical success, stent migration, and adverse events. Twenty-five patients (7 males, 18 females) with a median age of 54 years (33-85 years) underwent 28 LAMS placements to treat various benign strictures. The location of the strictures included esophagogastric anastomoses (n=4), gastrojejunal anastomoses (n=13), pylorus (n=6), vertical banded gastroplasty (n=1), and ileocolonic anastomosis (n=1). Twenty patients had been previously treated with dilation alone (9 patients with ≥3 dilations), 11 patients with dilation and steroid injection, 2 patients with additional needle-knife therapy, and 1 patient with placement of a traditional fully covered self-expandable metal stent. A 15-mm internal diameter LAMS was placed in all patients; 3 patients had been treated previously with a 10-mm LAMS. Technical success was achieved in all patients, whereas clinical success was achieved in 15 of 25 patients (60%) who completed a minimum of 6 months of follow-up after placement. Median stent dwell time was 92 days (range, 3-273 days). Stent migration was seen in 2 of 28 stent placements (7%). Four of 25 patients (16%) developed 5 moderate adverse events (pain requiring removal, 2; new stricture formation, 2; bleeding, 1). Median follow-up was 301 days after stent placement. Study limitations include the small, select group of patients, the retrospective study design, and short follow-up. LAMS placement for benign GI strictures is technically easy and safe with low migration rates and may be an option to treat selected patients with short-length strictures.

Background and Objectives: Prevention of the periodontal disease progression is the primary goal of periodontal therapy. When conventional therapy is found inadequate to attain periodontal health in chronic periodontitis, local antimicrobial agents have been used as an adjunct with scaling and root planning (SRP) which has reproduced encouraging results. Hence, this study was undertaken to evaluate the new sustained released local drug Chlosite clinically and microbiologically in smokers and non-smokers. Materials and Methods: The patients were grouped into experimental group A treated with SRP plus Chlosite (SRP + CHL), experimental group B treated with Chlosite alone (CHL), and control group C treated only with SRP alone. A total number of 141 sites from six patients (67 sites from three non-smoker patients and 74 sites from three smoker patients) participated in this study. The clinical parameters, Plaque index (PI), Gingival index (GI), Bleeding index (BI), and Relative attachment level (RAL), were recorded and subgingival plaque samples were collected and subjected to microbiological analysis. Results: On comparison of smokers and non-smokers, in SRP group, non-smokers showed a higher reduction in BI and GI and smokers showed a higher reduction in PI. There was no significant gain in RAL of both smokers and non-smokers. In SRP + CHL group, non-smokers showed a higher reduction in relation to BI and GI and smokers showed a higher reduction in relation to PI. There was no significant gain in RAL of both smokers and non-smokers. In CHL group, both smokers and non-smokers showed a nonsignificant reduction in BI, GI, and RAL, but smokers showed a significant reduction in PI as compared with non-smokers. All the groups showed reduction in the microbial count of Fusobacterium nucleatum, Porphyromonas gingivalis, and Tannerella forsythia which were found to be statistically not significant when it was compared between non-smokers and smokers. Interpretation and Conclusion: In this study, all treatment groups were found to be efficacious in the treatment of periodontal disease as demonstrated by improvement in PI, GI, BI, and RAL. Combination of SRP and Chlosite resulted in added benefits compared with the two treatment groups. PMID:22028508

Inner myometrial laceration - an unusual presentation of antepartum and postpartum hemorrhage: case reports and review of the literature.

The aim of this study is to evaluate the diagnostic criteria, treatment options and progression of cases who have antenatal or postpartum hemorrhage due to internal myometrial laceration (IML) and to review the literature. The files of eight patients who were diagnosed to have IML between August 2012 and July 2015 were evaluated retrospectively. The patient group consisted of four patients who had an emergency c-section due to massive bleeding during labor and four patients who had an emergency laparotomy due to uncontrolled bleeding after vaginal delivery after evaluation of the patient for signs of 4Ts (trauma, tissue retention, uterine tonus, and trombin). Primary suturation was the first-line treatment in all patients. In two of the patients, hysterectomy was performed after the defined surgical procedures were not successful in controling the bleeding. The presented case series is a pioneering study that describes IM which is a poorly defined reason of postpartum hemorrhage, as the cause of bleeding during labor. Primary suturation is the first-step, further surgery might be required in order to treat this life-threathening condition and the decision should be based on the age and the fertility status of the patient.

A 29-year-old woman (gravida 1, para 1) had an uneventful first pregnancy and a delivery by emergency caesarean section at term. The caesarean section was complicated by a massive obstetric haemorrhage of 5000 ml. After closure, an immediate re-laparotomy was indicated due to heavy vaginal bleeding. The site of bleeding was identified as an extension of the uterine incision, and was sutured. She was stabilised by transfusion of blood and blood products in the intensive therapy unit, and discharged 5 days later. The patient was re-admitted 6 weeks later with brisk, painless vaginal bleeding, passing large clots from a well-contracted uterus. Her haemoglobin decreased from 11.8 to 7.8 g/dl overnight. In view of her history, an urgent CT angiogram was performed, which revealed the presence of a pseudo-aneurysm arising from the left uterine artery. This was successfully occluded by transarterial embolisation, obviating the need for further surgical exploration. PMID:22674937

To assess the efficacy and safety of diverting colostomy in treating severe hemorrhagic chronic radiation proctitis (CRP). Patients with severe hemorrhagic CRP who were admitted from 2008 to 2014 were enrolled into this study. All CRP patients were diagnosed by a combination of pelvic radiation history, clinical rectal bleeding, and endoscopic findings. Inclusion criteria were CRP patients with refractory bleeding with moderate to severe anemia with a hemoglobin level < 90 g/L. The study group included patients who were treated by diverting colostomy, while the control group included patients who received conservative treatment. The remission of bleeding was defined as complete cessation or only occasional bleeding that needed no further treatment. The primary outcome was bleeding remission at 6 mo after treatment. Quality of life before treatment and at follow-up was evaluated according to EORTC QLQ C30. Severe CRP complications were recorded during follow-up. Forty-seven consecutive patients were enrolled, including 22 in the colostomy group and 27 in the conservative treatment group. When compared to conservative treatment, colostomy obtained a higher rate of bleeding remission (94% vs 12%), especially in control of transfusion-dependent bleeding (100% vs 0%), and offered a better control of refractory perianal pain (100% vs 0%), and a lower score of bleeding (P < 0.001) at 6 mo after treatment. At 1 year after treatment, colostomy achieved better remission of both moderate bleeding (100% vs 21.5%, P = 0.002) and severe bleeding (100% vs 0%, P < 0.001), obtained a lower score of bleeding (0.8 vs 2.0, P < 0.001), and achieved obvious elevated hemoglobin levels (P = 0.003), when compared to the conservative treatment group. The quality of life dramatically improved after colostomy, which included global health, function, and symptoms, but it was not improved in the control group. Pathological evaluation after colostomy found diffused chronic inflammation cells, and massive fibrosis collagen depositions under the rectal wall, which revealed potential fibrosis formation. Diverting colostomy is a simple, effective and safe procedure for severe hemorrhagic CRP. Colostomy can improve quality of life and reduce serious complications secondary to radiotherapy.

Renal cell carcinoma arising in a horseshoe kidney is a rare entity. Preoperative tumor embolization can be performed to prevent massive bleeding complications during organ-preserving surgery. We report the first case of a patient with a tumor-bearing horseshoe-kidney in whom the preoperative embolization, already complex because of the abnormal vascular supply, was additionally complicated by an aortic dissection. An aberrant, horseshoe-kidney-supplying artery originated from the false dissection channel of the aorta, and thus had to be catheterized separately while the other tumor-supplying vessels could be reached via the true aortic lumen. After devascularization of the tumor, organ-preserving surgery was performedmore » without bleeding complications.« less

Delayed hemothorax after blunt torso injury is rare, but might be associated with significant morbidity and mortality. We present a case of delayed hemothorax bleeding from phrenic artery injury in a 24-year-old woman. The patient suffered from multiple rib fractures on the right side, a right hemopneumothorax, thoracic vertebral injury and a pelvic bone fracture after a fall from a fourth floor window. Delayed hemothorax associated with phrenic artery bleeding, caused by a stab injury from a fractured rib segment, was treated successfully by a minimally invasive thoracoscopic surgery. Here, we have shown that fracture of a lower rib or ribs might be accompanied by delayed massive hemothorax that can be rapidly identified and promptly managed by thoracoscopic means.

Hemoptysis.

PubMed

Corder, Robert

2003-05-01

Hemoptysis is a common complaint the emergency physician encounters. Most cases are minor and treatable or self-limited. In many cases a cause is never determined. Massive hemoptysis is an occasional occurrence that must be assessed and managed swiftly. The initial approach is no different than that for any bleeding or respiratory or hemodynamically unstable patient. The emergency physician must stabilize, localize, and stop bleeding, and include required specialists to achieve that purpose. The management suggestions presented in this article are simplistic. The emergence of improved CT technology and new bronchoscopic and angiographic techniques has provided safe and effective alternatives to surgery for many causes of hemoptysis. Surgery, however, continues to be the treatment of choice for some. Being familiar with the broad list of causes is imperative to keeping an approach organized.

Objective: To investigate the clinical efficacy, safety and promotion value of TB type thermal balloon endometrial ablation in the treatment of abnormal uterine bleeding. Methods: Fourty three patients who had received TB type endometrial ablation system for treatment of abnormal uterine bleeding from January, 2015 to January, 2016 in theDepartment of gynecology, Beijing Chaoyang Hospital were enrolled in this study. The intra-operative and post-operative complications and improvement of abnormal uterine bleeding and dysmenorrhea were observed. Results: There were nointra-operative complication occurred, such as uterine perforation, massive hemorrhage or surrounding organ damage. At 6 months after operation, 32 patients developed amenorrhea, 6 developed menstrual spotting, 3 developed menstruation with a small volume and 1 had a normal menstruation. No menstruation with an increased volume occurred. The occurrence of amenorrhea was 76.19% and the response rate was 97.62%.At 6 months after operation, 1 case had no response, 2 cases had partial response and 11 cases had complete response among the 14 cases of pre-operative dysmenorrhea; only 3 cases still had anemia among the 23 cases of pre-operative anemia. Compared with before treatment, patients with dysmenorrhea and anemia both significantly reduced with a statistically significant difference( P <0.01). Conclusion: TB type thermal balloon endometrial ablation has a significant efficacy with high safety for the treatment of abnormal uterine bleeding, which could have clinical promotion practice.

Abstract Gastrointestinal involvement is rare in Behçet's syndrome (BS) patients from the Mediterranean basin. We report the demographic and disease characteristics, treatment modalities, and outcome of patients with gastrointestinal involvement in BS (GIBS). We retrospectively reviewed the charts of all BS patients in our BS clinic with a diagnosis of GIBS. Patients were invited to the clinic to assess their outcome. Among 8763 BS patients, we identified 60 with GIBS (M/F: 32/28, mean age at diagnosis: 34 ± 10, mean follow-up: 7.5 ± 4 years), after excluding 22 patients with mimicking symptoms. Six (10%) had juvenile-onset BS. The most common intestinal localization was ileocecal region (36/59, 61%) mainly as big oval ulcer/s. Initial treatment was azathioprine for moderate to severe (n = 37) and 5-ASA for mild cases (n = 16). Anti-TNFs and/or thalidomide provided remission in 12 of 18 (67%) refractory patients. Emergency surgery was required in 22 patients. Nine patients did not receive postoperative immunomodulators and 8 relapsed. Overall, 48 of 60 (80%) patients were in remission (29/48 without treatment) at the time of survey. Three recently treated and 2 refractory patients were still active, 3 had died due to non-GI-related reasons, and 4 were lost to follow-up. Careful evaluation for excluding mimickers is important during the diagnosis of GIBS. Azathioprine seems to be a good choice as first-line treatment with high remission rates and few adverse events. Thalidomide and/or TNF-alpha antagonists may be preferred in resistant cases. Surgery may be required for perforations or massive bleeding, and postoperative immunosuppressive treatment is necessary for preventing postoperative recurrences. PMID:27100417

Upper GI bleeding remains one of the most common emergencies with a substantial overall mortality rate of up to 30%. In severe ill patients, death does not occur due to failure of hemostasis, either medical or surgical, but mainly from comorbidities, treatment complications, and decreased tolerated blood loss. Management strategies have changed dramatically over the last two decades and include primarily endoscopic intervention in combination with acid-suppressive therapy and decrease in surgical intervention. Herein, we present one of the largest patient-based analysis assessing clinical parameters and outcome in patients undergoing endoscopy with an upper GI bleeding. Data were further analyzed to identify potential new risk factors and to investigate the role of surgery. In this retrospective study, we aimed to analyze outcome of patients with an UGIB and data were analyzed to identify potential new risk factors and the role of surgery. Data collection included demographic data, laboratory results, endoscopy reports, and details of management including blood administration, and surgery was carried out. Patient events were grouped and defined as "overall" events and "operated," "non-operated," and "operated and death" as well as "non-operated and death" where appropriate. Blatchford, clinical as well as complete Rockall-score analysis, risk stratification, and disease-related mortality rate were calculated for each group for comparison. Overall, 253 patients were eligible for analysis: endoscopy was carried out in 96% of all patients, 17% needed surgical intervention after endoscopic failure of bleeding control due to persistent bleeding, and the remaining 4% of patients were subjected directly to surgery. The median length of stay to discharge was 26 days. Overall mortality was 22%; out of them, almost 5% were operated and died. Anticoagulation was associated with a high in-hospital mortality risk (23%) and was increased once patients were taken to surgery (43%). Patients taking steroids presented with a risk of death of 26%, once taken to surgery the risk increased to 80%. Patients with liver cirrhosis had a risk of death of 42%; we observed a better outcome for these patients once taken to theater. Clinically, once scored with Blatchford score, statistical correlation was found for initial need for blood transfusion and surgical intervention. Clinical as well as complete Rockall score revealed a correlation between need for blood transfusion as well as surgical intervention in addition with a decreased outcome with increasing Rockall scores. Risk factor analysis including comorbidity, drug administration, and anticoagulation therapy introduced the combination of tumor and non-steroidal antirheumatic medication as independent risk factors for increased disease-related mortality. UGIB remains challenging and endoscopy is the first choice of intervention. Care must be taken once a patient is taking antirheumatic non-steroidal pain medication and suffers from cancer. In patients with presence of liver cirrhosis, an earlier surgical intervention may be considered, in particular for patients with recurrent bleeding. Embolization is not widely available and carries the risk of necrosis of the affected organ and should be restricted to a subgroup of patients not primarily eligible for surgery once endoscopy has failed. Taken together, an interdisciplinary approach including gastroenterologists as well as surgeons should be used once the patient is admitted to the hospital to define the best treatment option.

Initiation and Termination of Massive Transfusion Protocols: Current Strategies and Future Prospects.

Foster, John C; Sappenfield, Joshua W; Smith, Robert S; Kiley, Sean P

2017-12-01

The advent of massive transfusion protocols (MTP) has had a significant positive impact on hemorrhaging trauma patient morbidity and mortality. Nevertheless, societal MTP guidelines and individual MTPs at academic institutions continue to circulate opposing recommendations on topics critical to MTPs. This narrative review discusses up-to-date information on 2 such topics, the initiation and termination of an MTP. The discussion for each begins with a review of the recommendations and supporting literature presented by MTP guidelines from 3 prominent societies, the American Society of Anesthesiologists, the American College of Surgeons, and the task force for Advanced Bleeding Care in Trauma. This is followed by an in-depth analysis of the main components within those recommendations. Societal recommendations on MTP initiation in hemorrhaging trauma patients emphasize the use of retrospectively validated massive transfusion (MT) prediction score, specifically, the Assessment of Blood Consumption and Trauma-Associated Severe Hemorrhage scores. Validation studies have shown that both scoring systems perform similarly. Both scores reliably identify patients that will not require an MT, while simultaneously overpredicting MT requirements. However, each scoring system has its unique advantages and disadvantages, and this review discusses how specific aspects of each scoring system can affect widespread applicability and statistical performance. In addition, we discuss the often overlooked topic of initiating MT in nontrauma patients and the specific tools physicians have to guide the MT initiation decision in this unique setting. Despite the serious complications that can arise with transfusion of large volumes of blood products, there is considerably less research pertinent to the topic of MTP termination. Societal recommendations on MTP termination emphasize applying clinical reasoning to identify patients who have bleeding source control and are adequately resuscitated. This review, however, focuses primarily on the recommendations presented by the Advanced Bleeding Care in Trauma's MTP guidelines that call for prompt termination of the algorithm-guided model of resuscitation and rapidly transitioning into a resuscitation model guided by laboratory test results. We also discuss the evidence in support of laboratory result-guided resuscitation and how recent literature on viscoelastic hemostatic assays, although limited, highlights the potential to achieve additional benefits from this method of resuscitation.

Background Predictors of worse outcomes (rebleeding, surgery and death) of peptic ulcer bleeding (PUB’s) are essential indicators because of significant morbidity and mortality. rates of PUB’s. However those have been rarely infrequently reported since changes in medical therapy (proton poump inhibitors-PPI) and application of newer endoscopic hemostasis. Aim Our purposes were to determine: 1) independent risk factors of 30-day rebleeding, surgery, and death and 2) whether ulcer size is an independent predictor of major outcomes in patients with severe PUB’s after successful endoscopic hemostasis and treatment with optimal medical (high dose IV PPI) vs. prior treatment (high dose IV histamine 2 antagonists – H2RA’s). Methods A large prospectively followed population of patients hospitalized with severe PUB’s between 1993 and 2011 at two US tertiary care academic medical centers, stratified by stigmata of recent hemorrhage (SRH) was studied. Using multivariable logistic regression analyses, independent risk factors of each outcome (rebleeding, surgery, and death) up to 30 days were analyzed. Effects of medical treatment (H2RA patients 1993–2005 vs. PPI’s 2006–2011) were also analysed. Results 1264 patients were included. For ulcers ≥10mm, the odds of 30-day rebleeding increased 6% per each 10% increase in ulcer size (OR 1.06, 95%CI 1.02–1.10, p=0.0053). Other risk factors of 30-day rebleeding were major SRH, inpatient start of bleeding, and prior GI bleeding. Major SRH and ulcer size ≥10 mm were predictors of 30-day surgery. Risk factors of 30-day death were major SRH, inpatient bleeding, any initial platelet transfusion or fresh frozen plasma transfusion ≥2 units. Among patients with major SRH and outpatient start of bleeding, larger ulcer size was also a risk factor for death (OR 1.08 per 10% increase in ulcer size, 95%CI 1.02–1.14, p=0.0095). Ulcer size was a significant independent variable for both time periods. Conclusions Ulcer size is a risk factor and should be carefully recorded at initial endoscopy to improve patient triage and management. PMID:27000531

Nonsteroidal antiinflammatory drug (NSAID)-associated gastropathy is a major cause of hospitalization and death. This study was undertaken to examine whether recent preventive approaches have been associated with a declining incidence of NSAID gastropathy, and, if so, what measures may have caused the decline. We studied 5,598 patients with rheumatoid arthritis (RA) over 31,262 patient-years at 8 sites. We obtained standardized longitudinal information on the patients that had been previously used to establish the incidence of NSAID gastropathy, and also information on patient risk factors and differences in toxicity between NSAIDs. Consecutive patients were followed up with biannual Health Assessment Questionnaires and medical record audits between 1981 and 2000. The major outcome measure was the annual rate of hospitalization involving bleeding, obstruction, or perforation of the gastrointestinal (GI) tract and related conditions. Rates of GI-related hospitalizations rose from 0.6% in 1981 to 1.5% in 1992 (P < 0.001), and then declined to 0.5% in 2000 (P < 0.001). The fitted spline curve fit the data well (R2 = 0.70). The period of rise was mainly associated with increasing patient age and the GI risk propensity score. The period of decline was associated with lower doses of ibuprofen and aspirin, a decline in the use of "more toxic" NSAIDs from 52% to 42% of patients, a rise in the use of "safer" NSAIDs from 19% to 48% of patients, and increasing use of proton-pump inhibitors, but not with change in age, NSAID exposure, or GI risk propensity score. The risk of serious NSAID gastropathy has declined by 67% in these cohorts since 1992. We estimate that 24% of this decline was the result of lower doses of NSAIDs, while 18% was associated with the use of proton-pump inhibitors and 14% with the use of less toxic NSAIDs. These declines in the incidence of NSAID gastropathy are likely to continue.

The aim of this short-term study was to compare the clinical efficacy of 2 different methods to treat acute periodontal abscesses. After patient selection, 100 cases of acute periodontal abscess were randomly divided into two groups. The experimental group was treated by supra- and subgingival scaling, while the control group was treated by incision and drainage. A clinical examination was carried out to record the following variables: subjective clinical variables including pain, edema, redness and swelling; objective clinical variables including gingival index(GI), bleeding index(BI), probing depth(PD),suppuration, lymphadenopathy and tooth mobility. The data was analyzed with SPSS 19.0 software package. RESULES: Subjective clinical variables demonstrated statistically significant improvements with both methods from the first day after treatment and lasted for at least 30 days(P<0.05), but the results of experimental group showed much better than the control group 1 day and 7 days after treatment. 30 days after treatment, there was no significant difference between the two groups in pain and swelling improvement(P>0.05), but the experimental group showed more improvement in edema and redness than the control group(P<0.05).On improving objective variables, the experimental group showed significant improvement in GI,BI,PD and suppuration 1 day after treatment(P<0.05).After 7 days, all objective clinical variables in the experimental group improved significantly(P<0.05) in the control group, there were significant improvements in GI,suppuration,lymphadenopathy and tooth mobility(P<0.05) but the four variables of the experimental group showed more improvement than the control group(P<0.05).After 30 days, all objective clinical variables improved significantly in both groups as compared to baseline, but in the experimental group, improvements were more significant regarding to GI,BI,PD,suppuration and tooth mobility(P<0.05). The method of supra- and subgingival scaling was rapid and effective in treatment of acute periodontal abscesses.

Maintenance of good oral hygiene is important for patients undergoing fixed orthodontic treatment. The aim of this study was to evaluate the effectiveness of a manual orthodontic toothbrush, powered toothbrush with oscillating head and sonic toothbrush in controlling plaque, gingivitis and interdental bleeding in patients undergoing fixed orthodontic treatment, and to compare their relative efficacy. Sixty subjects, who were to receive orthodontic treatment with both upper and lower fixed appliances, were randomly divided into three study groups, with 20 patients in each group. Groups I to III were given manual orthodontic, powered and sonic toothbrushes, respectively. Plaque index (PI), gingival index (GI) and interdental bleeding index were scored to assess the level of plaque accumulation, gingival health and interdental bleeding at baseline; 4 and 8 weeks recall visits after fixed appliance bonding. Paired t-tests and one-way analysis of variance (ANOVA) tests were used for intragroup and intergroup comparisons. The level of statistical significance was set at p < 0.05. This study showed that a significant reduction in all the three indices scores was found from baseline to 4 and 8 weeks in group III. On intergroup comparison, no statistically significant differences were detected between the three groups for any of the parameters assessed. On intragroup comparison, sonic brushes performed superiorly in reducing gingivitis, plaque and interdental bleeding as compared to the manual orthodontic and powered brushes. On intergroup comparison, the relative comparative effectiveness was found to be similar for all the three brushes. How to cite this article: Sharma R, Trehan M, Sharma S, Jharwal V, Rathore N.

The aim of this study is to evaluate the clinical and microbiological effect of the systemic antibiotic therapy of proanthocyanidins and secnidazole on periodontitis. Seventy-five subjects with chronic periodontitis were randomly divided into two treatment groups (secnidazole or proanthocyanidins) and one placebo control group (25 cases each). Plaque index (PI), gingival index (GI), gingival bleeding index (BI), probing pocket depth (PPD), and clinical attachment level (CAL) were carried out at baseline, post-treatment and 3 months after treatment. Microbial analysis was performed at baseline and post-treatment. The results show that the two treatment groups had greater mean reduction in BI, GI, and PPD evaluated at both post-treatment and 3 months after treatment compared to the control group (p less than 0.05), but there were no significant differences in those of PI and CAL (except CAL evaluated at post-treatment, p 0.05). After treatment, culturable bacteria counts significantly decreased. In conclusion, the adjunctive use of proanthocyanidins or secnidazole in combination with scaling and root planing in adults with periodontitis is effective in reducing the pathogenic flora and achieves significantly better clinical results to a certain degree.

Introduction We present a patient who presented to the ICU after successful resuscitation from cardiac arrest who was subsequently diagnosed with AEN. Case Presentation A 66-year-old female presented after cardiac arrest in which return of spontaneous circulation was achieved within 7 minutes after the initiation of CPR. She was intubated on the scene and found to have coffee ground emesis in her bathroom when found unresponsive. Due to the hemodynamically significant GI bleed, patient was started on IV proton pump inhibitor, octreotide, and levophed. Subsequent endoscopy showed diffuse severe mucosal changes characterized by blackness, erythema, friability, granularity, inflammation, and decreased vascular pattern in the middle third of the esophagus and in the lower third of the esophagus. Discussion AEN is a rare syndrome with a prevalence ranging from 0.001 to 0.2% of EGD. This patient is especially rare as this patient was female and had AEN in the middle esophagus along with lower esophagus. The pathophysiology in this patient is hypothesized that she had cardiac arrest secondary to acute upper GI hemorrhage. Subsequent low-flow state (cardiac arrest) in addition to being in the setting of severe alcohol abuse led to esophageal necrosis. PMID:28706745

Maintaining a high level of periodontal and oral health in patients undergoing renal dialysis is of paramount importance because of the inherent compromised host defence mechanisms. The aim of the present study was to determine the periodontal status and the level of dental caries in renal dialysis patients in Kerman, Iran. A cross-sectional study was conducted on two groups of patients: one including 68 renal dialysis patients (test) and the other including 30 healthy subjects (control). Half-mouth measurements of Gingival Index (GI), Plaque Index (PI), probing pocket depth (PPD), gingival recession (GR), clinical attachment level (CAL) and bleeding on probing (BOP) as well as decayed, missing or filled teeth (DMFT) index were recorded. The GI, BOP, PPD, CAL and GR were significantly greater among the test group as compared with the control group; however, the DMFT did not differ significantly among the groups. There was no relationship between the duration of the dialysis and the periodontal indices. It seems that patients with chronic renal failure have less favourable periodontal health than normal patients. The present study showed that oral home care practices were inadequate. Thus, preventive programmes to promote the oral health status of haemodialysis patients are needed.

Purpose: To identify dosimetric parameters derived from anorectal, rectal, and anal wall dose distributions that correlate with different late gastrointestinal (GI) complications after three-dimensional conformal radiotherapy for prostate cancer. Methods and Materials: In this analysis, 641 patients from a randomized trial (68 Gy vs. 78 Gy) were included. Toxicity was scored with adapted Radiation Therapy Oncology Group/European Organization for the Research and Treatment of Cancer (RTOG/EORTC) criteria and five specific complications. The variables derived from dose-volume histogram of anorectal, rectal, and anal wall were as follows: % receiving {>=}5-70 Gy (V5-V70), maximum dose (D{sub max}), and mean dose (D{sub mean}).more » The anus was defined as the most caudal 3 cm of the anorectum. Statistics were done with multivariate Cox regression models. Median follow-up was 44 months. Results: Anal dosimetric variables were associated with RTOG/EORTC Grade {>=}2 (V5-V40, D{sub mean}) and incontinence (V5-V70, D{sub mean}). Bleeding correlated most strongly with anorectal V55-V65, and stool frequency with anorectal V40 and D{sub mean}. Use of steroids was weakly related to anal variables. No volume effect was seen for RTOG/EORTC Grade {>=}3 and pain/cramps/tenesmus. Conclusion: Different volume effects were found for various late GI complications. Therefore, to evaluate the risk of late GI toxicity, not only intermediate and high doses to the anorectal wall volume should be taken into account, but also the dose to the anal wall.« less

We present an uncommon case of a carcinoid tumour of the bronchus that was diagnosed during pregnancy in a 28-year-old woman. The patient was admitted at the emergency department with massive haemoptysis. Owing to the patient's critical condition, she underwent urgent flexible bronchoscopy. Bleeding was controlled by local injection of 500 mg tranexamic acid and electrocautery. After the bleeding has stopped, multiple specimens were taken. Histological examination confirmed typical carcinoid tumour. Owing to repeated haemoptysis, she was treated with bronchoscopic (electrocautery) therapy, and, after delivery, she underwent pulmonary lobectomy. Only a few similar cases were found in the literature reporting bronchopulmonary carcinoid tumour during pregnancy and we could not find any similar case which was treated by electrocautery.

Identification and immediate treatment of life-threatening conditions is fundamental in patients with multiple trauma. In this context, the S3 guidelines on polytrauma and the S1 guidelines on emergency anesthesia provide the scientific background on how to handle these situations. This case report deals with a seriously injured driver involved in a truck accident. The inaccessible patient showed a scalping injury of the facial skeleton with massive bleeding and partially blocked airway but with spontaneous breathing as well as centralized cardiovascular circulation conditions and an initial Glasgow coma scale (GCS) of 8. An attempt was made to stop the massive bleeding by using hemostyptic-coated dressings. In addition, the patient was intubated via video laryngoscopy and received a left and right thoracic drainage as well as two entry points for intraosseous infusion. In modern emergency medical services, treatment based on defined algorithms is recommended and also increasingly established in dealing with critical patients. The guideline-oriented emergency care of patients with polytrauma requires invasive measures, such as intubation and thoracic decompression in the preclinical setting. The foundation for this procedure includes training in theory and practice both of the non-medical and medical rescue service personnel.

Portal hypertensive gastropathy: A systematic review of the pathophysiology, clinical presentation, natural history and therapy.

2016-02-08

To describe the pathophysiology, clinical presentation, natural history, and therapy of portal hypertensive gastropathy (PHG) based on a systematic literature review. Computerized search of the literature was performed via PubMed using the following medical subject headings or keywords: "portal" and "gastropathy"; or "portal" and "hypertensive"; or "congestive" and "gastropathy"; or "congestive" and "gastroenteropathy". The following criteria were applied for study inclusion: Publication in peer-reviewed journals, and publication since 1980. Articles were independently evaluated by each author and selected for inclusion by consensus after discussion based on the following criteria: Well-designed, prospective trials; recent studies; large study populations; and study emphasis on PHG. PHG is diagnosed by characteristic endoscopic findings of small polygonal areas of variable erythema surrounded by a pale, reticular border in a mosaic pattern in the gastric fundus/body in a patient with cirrhotic or non-cirrhotic portal hypertension. Histologic findings include capillary and venule dilatation, congestion, and tortuosity, without vascular fibrin thrombi or inflammatory cells in gastric submucosa. PHG is differentiated from gastric antral vascular ectasia by a different endoscopic appearance. The etiology of PHG is inadequately understood. Portal hypertension is necessary but insufficient to develop PHG because many patients have portal hypertension without PHG. PHG increases in frequency with more severe portal hypertension, advanced liver disease, longer liver disease duration, presence of esophageal varices, and endoscopic variceal obliteration. PHG pathogenesis is related to a hyperdynamic circulation, induced by portal hypertension, characterized by increased intrahepatic resistance to flow, increased splanchnic flow, increased total gastric flow, and most likely decreased gastric mucosal flow. Gastric mucosa in PHG shows increased susceptibility to gastrotoxic chemicals and poor wound healing. Nitrous oxide, free radicals, tumor necrosis factor-alpha, and glucagon may contribute to PHG development. Acute and chronic gastrointestinal bleeding are the only clinical complications. Bleeding is typically mild-to-moderate. Endoscopic therapy is rarely useful because the bleeding is typically diffuse. Acute bleeding is primarily treated with octreotide, often with concomitant proton pump inhibitor therapy, or secondarily treated with vasopressin or terlipressin. Nonselective β-adrenergic receptor antagonists, particularly propranolol, are used to prevent bleeding after an acute episode or for chronic bleeding. Iron deficiency anemia from chronic bleeding may require iron replacement therapy. Transjugular-intrahepatic-portosystemic-shunt and liver transplantation are highly successful ultimate therapies because they reduce the underlying portal hypertension. PHG is important to recognize in patients with cirrhotic or non-cirrhotic portal hypertension because it can cause acute or chronic GI bleeding that often requires pharmacologic therapy.

Report of a rare case of severe bleeding from the middle ear cavity after myringotomy. On the basis of the case report, the procedure for such bleeding is discussed in the context of the literature. A 6-year-old boy received a revision myringotomy in an ambulant setting. During the procedure a severe bleeding occurred. The external auditory canal was adequately packed. The patient was extubated and transferred to the clinic as an emergency. Computer tomography of the temporal bone showed the anatomical variant of a dehiscent high jugular bulb, which had been injured. Because no rebleeding occurred, the packing of the ear canal was removed and an explorative tympanoscopy was performed on the third postoperative day. When the tympanomeatal flap was lifted, the defect in the jugular bulb was found. The lesion was covered with Tutopatch ® pads and fibrin glue and the auditory canal was packed again. After removal of the packing three weeks postoperatively a properly healed situs was found. No further measures were taken. The injury of a dehiscent jugular bulb in the course of ear surgeries leads to a massive hemorrhage. The case describes the diagnostic and therapeutic procedure for this relatively rare but severe complication. © Georg Thieme Verlag KG Stuttgart · New York.

[Haemothorax after blunt thoracic trauma].

Siller, J; Havlícek, K

Haemothorax is frequent consequence of blunt and penetrating thoracic trauma and is usually associated with pneumothorax. The occurence of haemothorax in blunt thoracic trauma patients is estimated between 25-75%. The reason of bleeding is impairment of intercostal arteries or lung parenchyma after trauma of the ribs. Uncontrolled bleeding is the main cause of the death. The article is focused on the treatment of this injury. There were enrolled 238 patients with thoracic trauma, who were admitted into our department, into the study. The average age of the patients was 42.5 years. The ISS > or = 16 were in 101 patients. Forty two patients were artefitially ventilated. Conservative treatment prevails, almost in 65%. Special care was indicated in patients with haemothorax (fluidotoraxem). Clinically and based on other screening methods the presence of the fluid in thoracic cavity was in 131 patients. Surgical treatment (punction, drainage, videothoracoscopy and thoracotomy) was necessary in 47 (35.0%). Thoracotomy for the bleeding was indicated in seven cases (5.3 %). In diagnostics and in treatment of the bleeding in thoracic trauma patients the most important factor is clinical status of the patient. Indication for thoracotomy must be unambigous. Massive haemotorax leads to restrictive ventilation disorder with decreased preload and can be activator of the haemocolaguation disorders. This fact decreases chance for the survival of the patient.

Massive malignant hemothorax (MMH) is a rare and serious complication encountered in the field of oncology and can be life threatening. It is often difficult and complex to manage. Herein, we present cases of four patients who had MMH and in whom a hemothorax was successfully stopped via continuous intrapleural irrigation with epinephrine (5-mg epinephrine/1,000-mL normal saline, infused at 100 mL/h) instead of a conventional surgical approach. Although no patient deaths were attributed to intractable bleeding, two deaths were related to multiple organ failure. Despite the limited number of cases, this method was a convenient, effective, and inexpensive alternative to open surgical or thoracoscopic drainage for MMH.

We aimed to analyse late toxicity associated with external beam radiation therapy (EBRT) for prostate cancer using uniform dose-fractionation and beam arrangement, with the focus on the effect of 3D (CT) simulation and portal field size. We collected data concerning patients with localized prostate adenocarcinoma who had been treated with EBRT at five institutions in Osaka, Japan, between 1998 and 2006. All had been treated with 70 Gy in 35 fractions, using the classical 4-field technique with gantry angles of 0°, 90°, 180° and 270°. Late toxicity was evaluated strictly in terms of the Common Terminology Criteria for Adverse Events Version 4.0. In total, 362 patients were analysed, with a median follow-up of 4.5 years (range 1.0-11.6). The 5-year overall and cause-specific survival rates were 93% and 96%, respectively. The mean ± SD portal field size in the right-left, superior-inferior, and anterior-posterior directions was, respectively, 10.8 ± 1.1, 10.2 ± 1.0 and 8.8 ± 0.9 cm for 2D simulation, and 8.4 ± 1.2, 8.2 ± 1.0 and 7.7 ± 1.0 cm for 3D simulation (P < 0.001). No Grade 4 or 5 late toxicity was observed. The actuarial 5-year Grade 2-3 genitourinary and gastrointestinal (GI) late toxicity rates were 6% and 14%, respectively, while the corresponding late rectal bleeding rate was 23% for 2D simulation and 7% for 3D simulation (P < 0.001). With a uniform setting of classical 4-field 70 Gy/35 fractions, the use of CT simulation and the resultant reduction in portal field size were significantly associated with reduced late GI toxicity, especially with less rectal bleeding.

We report our 5-year experience of continuous flow left ventricular assist device (LVAD) implantation without the use of anti-platelet therapy. Between February 2006 and September 2011, 27 patients (26 men; 1 woman) were implanted with a continuous flow LVAD (HeartMate II, Thoratec Corporation, Pleasanton, CA, USA). The mean age was 55.7 ± 9.9 years. The mean duration of support was 479 ± 436 (1-1555) days with 35.4 patient-years on support. Twenty-one patients were implanted as a bridge to transplantation and 6 for destination therapy. The anticoagulation regimen was fluindione for all patients, with aspirin for only 4 patients. At the beginning of our experience, aspirin was administered to 4 patients for 6, 15, 60 and 460 days. Due to gastrointestinal (GI) bleeding and epistaxis, aspirin was discontinued, and since August 2006, no patients have received anti-platelet therapy. At 3 years, the survival rate during support was 76%. The most common postoperative adverse event was GI bleeding (19%) and epistaxis (30%) (median time: 26 days) for patients receiving fluindione and aspirin. The mean International Normalized Ratio (INR) was 2.58 ± 0.74 during support. Fifteen patients have been tested for acquired Von Willebrand disease. A diminished ratio of collagen-binding capacity and ristocetin cofactor activity to Von Willebrand factor antigen was observed in 7 patients. In the postoperative period, 2 patients presented with ischaemic stroke at 1 and 8 months. One of these 2 patients had a previous history of carotid stenosis with ischaemic stroke. There were no patients with haemorrhagic stroke, transient ischaemic attack or pump thrombosis. The event rate of stroke (ischaemic and haemorrhagic) per patient-year was 0.059 among the patients without aspirin with fluindione regimen only. A fluindione regimen without aspirin in long-duration LVAD support appears to not increase thromboembolic events and could lead to a diminished risk of haemorrhagic stroke.

Celecoxib for the treatment of pain resulting from osteoarthritis (OA) was reviewed by the Tandvårds- och läkemedelsförmånsverket-Dental and Pharmaceutical Benefits Board (TLV) in Sweden in late 2010. This study aimed to evaluate the incremental cost-effectiveness ratio (ICER) of celecoxib plus a proton pump inhibitor (PPI) compared to diclofenac plus a PPI in a Swedish setting. The National Institute for Health and Care Excellence (NICE) in the UK developed a health economic model as part of their 2008 assessment of treatments for OA. In this analysis, the model was reconstructed and adapted to a Swedish perspective. Drug costs were updated using the TLV database. Adverse event costs were calculated using the regional price list of Southern Sweden and the standard treatment guidelines from the county council of Stockholm. Costs for treating cardiovascular (CV) events were taken from the Swedish DRG codes and the literature. Over a patient's lifetime treatment with celecoxib plus a PPI was associated with a quality-adjusted life year (QALY) gain of 0.006 per patient when compared to diclofenac plus a PPI. There was an increase in discounted costs of 529 kr per patient, which resulted in an incremental cost-effectiveness ratio (ICER) of 82,313 kr ($12,141). Sensitivity analysis showed that treatment was more cost effective in patients with an increased risk of bleeding or gastrointestinal (GI) complications. The results suggest that celecoxib plus a PPI is a cost effective treatment for OA when compared to diclofenac plus a PPI. Treatment is shown to be more cost effective in Sweden for patients with a high risk of bleeding or GI complications. It was in this population that the TLV gave a positive recommendation. There are known limitations on efficacy in the original NICE model.

Channeling in the Use of Nonprescription Paracetamol and Ibuprofen in an Electronic Medical Records Database: Evidence and Implications.

Over-the-counter analgesics such as paracetamol and ibuprofen are among the most widely used, and having a good understanding of their safety profile is important to public health. Prior observational studies estimating the risks associated with paracetamol use acknowledge the inherent limitations of these studies. One threat to the validity of observational studies is channeling bias, i.e. the notion that patients are systematically exposed to one drug or the other, based on current and past comorbidities, in a manner that affects estimated relative risk. The aim of this study was to examine whether evidence of channeling bias exists in observational studies that compare paracetamol with ibuprofen, and, if so, the extent to which confounding adjustment can mitigate this bias. In a cohort of 140,770 patients, we examined whether those who received any paracetamol (including concomitant users) were more likely to have prior diagnoses of gastrointestinal (GI) bleeding, myocardial infarction (MI), stroke, or renal disease than those who received ibuprofen alone. We compared propensity score distributions between drugs, and examined the degree to which channeling bias could be controlled using a combination of negative control disease outcome models and large-scale propensity score matching. Analyses were conducted using the Clinical Practice Research Datalink. The proportions of prior MI, GI bleeding, renal disease, and stroke were significantly higher in those prescribed any paracetamol versus ibuprofen alone, after adjusting for sex and age. We were not able to adequately remove selection bias using a selected set of covariates for propensity score adjustment; however, when we fit the propensity score model using a substantially larger number of covariates, evidence of residual bias was attenuated. Although using selected covariates for propensity score adjustment may not sufficiently reduce bias, large-scale propensity score matching offers a novel approach to consider to mitigate the effects of channeling bias.

The Register was aimed at monitoring the use, possible side effects, and clinical effectiveness of Xigris® - drotrecogin alfa (activated) - for the treatment of severe sepsis in Italian intensive care units (ICUs). Data collection was performed using an online web form or a specific electronic module of the software Margherita, available only for the ICUs adhering to the GiViTI. Drug purchase information available for each center was used to identify and stimulate collaboration of non-compliant centers. Several countermeasures were taken to have the largest participation. We analyzed data from 1001 patients treated in 161 ICUs between July 2003 and September 2007, corresponding to 70% of all the patients who received the drug in that period. The off-label use of the drug was frequent: 15.6% of cases before and 27.3% after the label change with the introduction of timing restrictions. Treatment was temporarily interrupted in 10%, and definitely stopped in 25% of cases, after the occurrence of adverse events, the most frequent being bleeding. Severe bleeding occurred in 3.8% of patients. Multivariable analysis, which allowed an adjusted comparison with a control group, showed that treatment increased mortality among elective-surgery patients (OR 2.79, 95%CI 1.31-5.97). The results of this study and other evidences led the European Medicines Agency (EMA) to require a confirmatory trial in 2007. In October 2011 Ely-Lilly, the producer of the drug, announced the worldwide withdrawal from the market of Xigris®, on the basis of the negative results of the confirmatory trial. The availability of purchase information is essential to carry out post-marketing drug surveillance studies, since it allows to identify and contact non-compliant centers. Actually, a representative sample of treated patients provides reliable information on the use, efficacy, and safety of the drug in daily clinical practice that could positively influence healthcare policies.

Granulocytes and Vascularization Regulate Uterine Bleeding and Tissue Remodeling in a Mouse Menstruation Model

Menstruation-associated disorders negatively interfere with the quality of life of many women. However, mechanisms underlying pathogenesis of menstrual disorders remain poorly investigated up to date. Among others, this is based on a lack of appropriate pre-clinical animal models. We here employ a mouse menstruation model induced by priming mice with gonadal hormones and application of a physical stimulus into the uterus followed by progesterone removal. As in women, these events are accompanied by menstrual-like bleeding and tissue remodeling processes, i.e. disintegration of decidualized endometrium, as well as subsequent repair. We demonstrate that the onset of bleeding coincides with strong upregulation of inflammatory mediators and massive granulocyte influx into the uterus. Uterine granulocytes play a central role in regulating local tissue remodeling since depletion of these cells results in dysregulated expression of matrix modifying enzymes. As described here for the first time, uterine blood loss can be quantified by help of tampon-like cotton pads. Using this novel technique, we reveal that blood loss is strongly reduced upon inhibition of endometrial vascularization and thus, is a key regulator of menstrual bleeding. Taken together, we here identify angiogenesis and infiltrating granulocytes as critical determinants of uterine bleeding and tissue remodeling in a mouse menstruation model. Importantly, our study provides a technical and scientific basis allowing quantification of uterine blood loss in mice and thus, assessment of therapeutic intervention, proving great potential for future use in basic research and drug discovery.

Background & aims Improved medical decisions by using a score at the initial patient triage level may lead to improvements in patient management, outcomes, and resource utilization. There is no validated score for management of lower gastrointestinal bleeding (LGIB) unlike for upper GIB. The aim of our study was to compare the accuracies of 3 different prognostic scores (CURE Hemostasis prognosis score, Charlston index and ASA score) for the prediction of 30 day rebleeding, surgery and death in severe LGIB. Methods Data on consecutive patients hospitalized with severe GI bleeding from January 2006 to October 2011 in our two-tertiary academic referral centers were prospectively collected. Sensitivities, specificities, accuracies and area under the receiver operating characteristic (AUROC) were computed for three scores for predictions of rebleeding, surgery and mortality at 30 days. Results 235 consecutive patients with LGIB were included between 2006 and 2011. 23% of patients rebled, 6% had surgery, and 7.7% of patients died. The accuracies of each score never reached 70% for predicting rebleeding or surgery in either. The ASA score had a highest accuracy for predicting mortality within 30 days (83.5%) whereas the CURE Hemostasis prognosis score and the Charlson index both had accuracies less than 75% for the prediction of death within 30 days. Conclusions ASA score could be useful to predict death within 30 days. However a new score is still warranted to predict all 30 days outcomes (rebleeding, surgery and death) in LGIB. PMID:25599218

Diagnostic codes in the medical records of a large group-model HMO in northern California with approximately 3 million members were examined to identify patients with either rheumatoid arthritis (RA) or non-RA (osteoarthritis or degenerative joint disease). RA and non-RA patients were stratified in deciles of relative risk for gastrointestinal (GI) complications according to patient characteristics identified on the Standardized Calculator of Risk for Events (SCORE) that were associated with use of Cox-2 selective NSAIDs. (The SCORE tool stratifies patients by risk of serious GI complications using patient characteristics that are assigned points during an office visit, including age, health status, diagnosis of rheumatoid arthritis, corticosteroid use, and history of GI ulcer or bleed.) The second stage of analysis examined the percentage of arthritis patients in each SCORE-risk decile who received a Cox-2 selective NSAID, lower-risk NSAID, or traditional NSAID during calendar year 1999. The study population consisted of 144,360 members with an arthritis diagnosis, approximately 4.8% of members in this HMO. The mean age was 62.8 years (SD = 14.1), 61% were female, 10,449 (7%) had rheumatoid arthritis (RA), and 133,911 (93%) had non-rheumatoid arthritis. A diagnosis of RA was the most significant predictor of Cox-2 NSAID use (OR=2.4; 95% CI=1.6-3.5), followed by a history of GI problems (OR=1.5; 95% CI=1.4- 1.6). Female gender, chronic steroid use, and age each increased the odds of receiving a Cox-2 selective NSAID by about 35% (P<0.001 for all). Approximately 8.3% of patients in the highest decile of risk and 1.5% of patients in the lowest decile of risk received a Cox-2 selective NSAID. Clinical characteristics of patients identified on the SCORE (GI-risk) tool were strongly associated with use of Cox-2-selective NSAIDs in this HMO. A 5.5-fold difference in utilization of Cox-2 selective NSAIDs was found among patients determined to be in the highest-risk decile versus patients in the lowest-risk decile. Future research should investigate how nonclinical factors play a role in the treatment decisions made by physicians.

Juvenile polyps involving the stomach are uncommon. Massive gastric juvenile polyposis is even rarer. We describe the clinicopathologic features of nine cases of massive gastric juvenile polyposis. All patients had anemia; four had hypoalbuminemia. The polyps were composed predominantly of dilated crypts lined by columnar epithelium and abundant edematous stroma with mixed inflammatory infiltrates. One patient had a poorly differentiated adenocarcinoma, arising in juvenile polyp-associated intraepithelial neoplasia. A second patient had a well-differentiated intramucosal adenocarcinoma arising in a juvenile polyp with high-grade dysplasia. Three of our cases had polyposis restricted to the stomach. Six (66.6%) had loss of SMAD4 immunoreactivity, making them subject to severe bleeding and hypoproteinemia, as well as developing severe dysplasia or adenocarcinoma. SMAD4 immunohistochemstry is a helpful ancillary diagnostic test in cases of suspected juvenile polyposis syndrome involving the stomach. © American Society for Clinical Pathology, 2017.

Background: Calendula officinalis (C. officinalis), commonly known as pot marigold, is a medicinal herb with excellent antimicrobial, wound healing, and anti-inflammatory activity. Aim: To evaluate the efficacy of C. officinalis in reducing dental plaque and gingival inflammation. Materials and Methods: Two hundred and forty patients within the age group of 20-40 years were enrolled in this study with their informed consent. Patients having gingivitis (probing depth (PD) ≤3 mm), with a complaint of bleeding gums were included in this study. Patients with periodontitis PD ≥ 4 mm, desquamative gingivitis, acute necrotizing ulcerative gingivitis (ANUG), smokers under antibiotic coverage, and any other history of systemic diseases or conditions, including pregnancy, were excluded from the study. The subjects were randomly assigned into two groups – test group (n = 120) and control group (n = 120). All the test group patients were advised to dilute 2 ml of tincture of calendula with 6 ml of distilled water and rinse their mouths once in the morning and once in the evening for six months. Similarly, the control group patients were advised to use 8 ml distilled water (placebo) as control mouthwash and rinse mouth twice daily for six months. Clinical parameters like the plaque index (PI), gingival index (GI), sulcus bleeding index (SBI), and oral hygiene index-simplified (OHI-S) were recorded at baseline (first visit), third month (second visit), and sixth month (third visit) by the same operator, to rule out variable results. During the second visit, after recording the clinical parameters, each patient was subjected to undergo a thorough scaling procedure. Patients were instructed to carry out regular routine oral hygiene maintenance without any reinforcement in it. Results: In the absence of scaling (that is, between the first and second visit), the test group showed a statistically significant reduction in the scores of PI, GI, SBI (except OHI-S) (P < 0.05), whereas, the control group showed no reduction in scores when the baseline scores were compared with the third month scores. Also, when scaling was performed during the third month (second visit), there was statistically significant reduction in the scores of all parameters, when the third month scores were compared with the sixth month scores in both groups (P < 0.05), but the test group showed a significantly greater reduction in the PI, GI, SBI, and OHI-S scores compared to those of the control group. Conclusion: Within the limits of this study, it can be concluded that calendula mouthwash is effective in reducing dental plaque and gingivitis adjunctive to scaling. PMID:24554883

The society for gastrointestinal intervention. Are we, as an organization of disparate disciplines, cooperative or competitive?

This is the Fourth Annual Meeting of the Society for Gastrointestinal Intervention, a multi-disciplinary group of practitioners committed to a minimally invasive approach to both the diagnosis and treatment of digestive disorders. The key concepts are minimally invasive and multi-disciplinary which can be construed as practicing in parallel with occasional lines of procedural and clinical interaction or inter-disciplinary in which patients are acutely cared for by a team, with treatments tailored to the patient and not the discipline that touches the patient first. In reality, many of us exist in both worlds. Most universities and large clinics are structured in departments along traditional training lines. As such, Interventional Radiology is housed in the Radiology Department, Laparoscopic Surgery (and potentially NOTES), as a component of the General Surgery Division, and Therapeutic Endoscopy usually resides within a gastroenterology structural framework. These divisions have historically been kept separate by multiple forces: salaries and budgets usually reside in a larger division. As a group, the amount of practice devoted to GI disorders is variable (for instance, minimally invasive surgeons may approach the adrenal glands or lung lesions in some institutions and interventional radiologists often sample tissue in multiple areas outside the GI tract, and by virtue of access to the vascular tree, can stent, embolize, or TPA almost any area of the body), as well as inherent differences in our individual abilities to access organs. I have already mentioned that angiographic capabilities allow the interventional radiologist access to virtually every GI organ and those capabilities allow therapeutic options for bleeding, tumor embolization, stenting of stenotic lesions, and formation of intravascular shunts. As such, there is very limited interdisciplinary competition here although capsule endoscopy as well as double and single balloon enteroscopy have improved the endoscopist's diagnostic and potential therapeutic reach. However, many of these diagnostic triumphs for obscure or massive GI bleed are simply to tattoo lesions that require surgical removal by laparoscopic or traditional surgery. Cooperation. However, there are potential competitive areas in the treatment of GI vascular lesions also. Whereas endoscopic band ligation has supplanted EVS, splenic devascularization, and most shunting procedures for patients with esophageal varices, endoscopic techniques have had less long-term success with glue injection for gastric varices. Multiple randomized, prospective trials have suggested therapeutic primacy of TIPS with embolization of recalcitrant vessels as an option or back-up. Despite this, therapeutic endoscopists have learned valuable lesions from our IR colleagues and studies are underway using endoscopically injected coils in addition to cyanoacrylate in an attempt to improve acute and long-term bleeding control. Nor is there any major competition in the treatment of primary or metastatic liver tumors by chemoembolization, RF current, or other thermal modalities, although selected patients with single lesions or multiple lesions isolated to a single lobe may be better handled surgically if there is curative intent. Finally, there is little IR, and progressively less, surgical competition for the treatment of high-grade dysplasia or superficial malignancies in the setting of Barrett's esophagus which are adequately treated in most patients by mucosectomy, RF ablation, or cryotherapy but require direct mucosal visualization to direct this therapy. The same has proven true for many years for colorectal polyps, superficial gastric cancers, and ampullary adenomas that had historically all been treated with major surgical resections. Still, there are many patients with advanced lesions who are good operative candidates who should be approached with conventional or minimally invasive surgery with the intent of operative cure. Cooperative, not competitive. The potential for competition between disciplines comes in mundane situations and clinical settings that have historically been "owned" by a single discipline. On the one hand, placement of PEGS and PEJs, initially done endoscopically, can be done with equal facility and occasional failure, by endoscopists and interventional radiologists, reserving failed attempts for minimally invasive surgery. What resources are utilized with these three methods? Are there advantages to defining the mucosa of the gut lumen in all, or even a subset of patients? By way of contrast, acute cholecystectomy tubes in high surgical risk patients have usually been the domain of the radiologist, although I described transcystic duct gallbladder decompression endoscopically 2½ decades ago. With the advent of new devices delivered under EUS control, the gallbladder will now be readily accessible endoscopically. What does this mean both for the acutely ill patient without a window to approach their gallbladder radiologically? Will this play a bit part and a cooperative technique to expand our therapeutic armamentarium or will it become competitive therapeutically not only for IR but for minimally invasive surgeons? The same may be said for EUS's ability to inject genes, caustics, or chemo-therapeutic agents into organs adjacent to the lumen. What is the role of TNFerade injection into unresectable pancreatic cancers and the role of absolute alcohol or Taxitol to treat cystic neoplasms of the pancreas? The real issue of competition or cooperation between the disciplines comes when treating patients with unresectable and obstructing GI neoplasms, from my perspective. The latter may occur almost anywhere in the GI tract but, of course, are more commonly noted proximally (esophagus, stomach, duodenum) and distally (left colon) as well as proximal and distal biliary obstructions. Recognizing that the occasional mid-small bowel and many proximal colon lesions are better handled with an endoscopic approach because of loss of vector force and difficulty pushing a catheter through large diameter, acutely angulated lumens, all others are fair game from my perspective. To my knowledge, although there are studies demonstrating the superiority of SEMS over open or laparoscopic bypass for malignant gastric outlet obstruction insofar as return of gut function, hospitalization time, and resource utilization, there are no studies demonstrating the superiority of one discipline or another in the placement of SEMS. Nor have cost data emerged suggesting the superiority of one technique over another from a cost standpoint. Unless or until we have such studies, this suggests to me that institutional interest and expertise should play a major role in how these unfortunate patients have continuity of their GI tract re-established. The situation is a bit more complex in pancreaticobiliary malignancy. There are 2 prospective randomized trials (level 1 evidence) that suggest that patients with proximal strictures (Bismuth II-IV) in conjunction with bile duct and gallbladder cancer, respectively, may be more successfully stented percutaneously and certainly it is easier to deliver brachytherapy or PDT under protocol to these patients who have indwelling external drains. In contrast, there are no data, positive or negative, to suggest that PTBD is a preferable treatment for distal biliary malignant obstruction, and in most parts of the world, the endoscopic approach has supplanted the percutaneous one just as metal stents have replaced plastic prostheses to preclude recurrent bouts of stent dysfunction and need for additional ERCP. The question posed at the beginning of this syllabus contribution: Are we competitive or cooperative? The answer is obviously both but, hopefully, our choice of treatment should depend less on who touches the patient first and more on skill sets within an institution and what is the best treatment for this particular individual. The importance of the SGI is technical and informational cross-fertilization. If your university or clinic will not allow blurring of training barriers to put therapeutic endoscopists, minimally invasive surgeons, and interventional radiologists together as a department or institute, you can nevertheless work together as a team in the best interest of your patients.

Background To evaluate roles of intraoperative endoscopy (IOE) in management of severe obscure GI bleeding (OGIB) before vs. after introduction of video capsule endoscopy (VCE) and deep enteroscopy (DE). Methods We retrospectively reviewed prospectively collected data of patients undergoing IOE for severe OGIB in a tertiary referral center. Results 52 patients had laparotomy/IOE for OGIB, 11 pre and 41 post VCE/DE eras. In the pre VCE/DE era, 36.4% (4/11) had preoperative presumptive diagnoses while in the post VCE/DE era presumptive diagnoses were made in 48.8% (20/41) (p= 0.18). Preoperative evaluation led to correct diagnoses in 18.2% (2/11) in the pre and 51.2% (21/41) in the post VCE/DE era (p=0.09). Vascular lesions and ulcers were the most common diagnoses, but rebleeding was common. No rebleeding was found among patients with tumors, Meckel's diverticulum, and aortoenteric fistula. Conclusions Presumptive diagnoses in the post VCE/DE era were usually accurate. If VCE or DE are negative, the probability of negative IOE is high. Patients with tumors and Meckel's diverticulum were the best candidates for IOE. PMID:28629608

Introduction. Citrullus colocynthis Schrad. is a commonly used medicinal plant especially as a hypoglycemic agent. Case Presentation. Four patients with colocynth intoxication are presented. The main clinical feature was acute rectorrhagia preceeded by mucosal diarrhea with tenesmus, which gradually progressed to bloody diarrhea and overt rectorrhagia within 3 to 4 hours. The only colonoscopic observation was mucosal erosion which was completely resolved in follow-up colonoscopy after 14 days. Conclusion. The membranolytic activity of some C. colocynthis ingredients is responsible for the intestinal damage. Patients and herbalists should be acquainted with the proper use and side effects of the herb. Clinicians should also be aware of C. colocynthis as a probable cause of lower GI bleeding in patients with no other suggestive history, especially diabetics. PMID:23819072

Lumbar segmental artery pseudoaneurysm after L5 pedicle screw placement. A rare vascular complication.

PubMed

Álvarez Postigo, M; Pizones Arce, J; Izquierdo Núñez, E

Posterior lumbar screw fixation is a common surgical procedure nowadays. However, it can sometimes produce complications that can be devastating. One of the less common causes of major complication is the misplacement of a pedicle screw. This highlights the importance of being methodical when placing pedicle screws, and checking that the pathway has been created correctly and their placement. We present a case of a massive bleed after a pedicular screw placement during lumbar canal stenosis surgery. Screw malposition led to intraoperative haemodynamic instability after failed attempts to control bleeding in the surgical site. Contrast enhanced CT imaging revealed a lumbar intersegmentary artery injury that was eventually controlled by means of a coil embolisation. Copyright © 2017 SECOT.

A 61-year-old man visited a physician complaining of progressive chest pain and dyspnea. The chest radiography showed complete collapse of the right lung suggesting tension pneumothorax. The patient was transferred to our hospital. A small amount of the right pleural effusion was also seen in addition to pulmonary collapse on the chest radiography. Chest drainage was performed, and continuous air leakage was seen. At 2 hours later, air leakage was disappeared but the bloody effusion was noted. The chest radiography revealed massive effusion and the enhanced computed tomography showed active bleeding. The emergency surgery was conducted. The bleeding point was a ruptured vessel between the apical parietal pleura and the pulmonary bulla. Hemostasis and the resection of the bullae was performed. Careful observation after chest drainage is necessary to prepare unexpected hemothorax in case of tension pneumothorax with pleural effusion.

Gelatin sponge (GS) is one of the most widely used embolic agents in interventional procedures. There are four commercially available GS products in Japan; however, the endovascular use of Gelfoam and Spongel is off-label, and Gelpart can only be used for hepatic artery embolization and Serescue can only be used for hemostasis of arterial bleeding. GS has been used for a variety of clinical indications, mainly tumor embolization and stopping massive arterial bleeding. The optimal size and preparation procedure of GS particles differs slightly for each clinical indication. In addition, there is a risk of ischemic and/or infectious complications associated with GS embolization in various situations. Therefore, radiologists should be familiar with not only the preparation and handling of GS particles, but also the disadvantages and potential risks, in order to perform GS embolization safely and effectively.

Gingivitis, an inflammation of the gingival tissues, typically progresses to periodontitis. The objective of this study is to estimate the prevalence of gingivitis in 35- to 70-year-olds residing in San Juan, Puerto Rico, and assess the differences in gingivitis distribution between age and gender groups. A cross-sectional epidemiological study was conducted with a sample of patients from a private practice and patients/employees of the Puerto Rico Medical Center. Participants completed a medical history questionnaire and received soft/hard tissue and gingival assessments based on a modified Löe-Silness index. Descriptive statistics were employed to estimate the overall gingivitis prevalence, severity (mild, moderate, severe), and mean gingival index (GI). Bleeding on probing (BOP) prevalence and the mean percentage of BOP sites were calculated by gender and age. Multinomial logistic regression was used to evaluate the associations between age, gender, and severity in 3 categories; multivariate logistic regression was used for having >=40% sites with BOP (vs. having <40% sites with BOP as reference). Odds ratios were also estimated. All 300 participants (52% women; 48% men) had gingivitis. The mean GI was 1.38. Moderate gingivitis was detected in 83% of the participants, mild in 7.3%, and severe in 9.3%. BOP was observed in 99% of the subjects (mean % BOP sites = 34%). After adjusting for age, men had significantly higher odds of moderate (OR = 4.66) and severe gingivitis (OR =10.06), compared to women, as well as 1.76 times higher odds of having 40% or more sites with BOP. Gingivitis was observed in all participants. Men had significantly higher GI, compared to women. The prevalence of gingivitis was higher in Puerto Rico than in the US.

Non-Steroidal Anti-Inflammatory Drugs (NSAIDs) Induced Dyspepsia.

PubMed

Yap, Paul Ray-Yee; Goh, Khean-Lee

2015-01-01

Non-steroidal anti-inflammatory drugs (NSAIDs) are the most prescribed group of drugs in the world. They are used primarily for pain relief in chronic inflammatory joint disease and act by inhibiting enzymes COX1 and COX2 and ultimately preventing the production of active prostanoids which are required for the innate inflammatory pathway. The use of NSAIDs have been associated with the development of gastrointestinal (GI) symptoms ranging from simple dyspepsia to life threatening GI bleeds and perforations. The definition of dyspepsia has evolved over the years and this has hampered accurate studies on the prevalence of dyspepsia as different studies used varying criteria to define dyspepsia. It is now known that NSAIDs significantly increase the risk of dyspepsia.The risk of developing peptic ulcer disease vary with specific NSAIDs and dosages but there is no correlation between the symptoms of dyspepsia and underlying peptic ulcers. The pathogenesis of dyspepsia with NSAIDs is not completely understood. Peptic ulceration alone is not able to account for the majority of dyspepsia symptoms encountered by NSAIDs users. Erosive oesophagitis secondary to NSAIDs may be contributing factor to the prevalence of dyspepsia in NSAIDs users. Altered gut permeability and changes in gastric mechanosensory function due to NSAIDs may also be a contributory factor. Management of NSAID induced dyspepsia is involves a multipronged approach. Drug avoidance if possible would be ideal. Other options include using the lowest effective dose, changing to an NSAIDs with a safer GI risk profile, avoiding concurrent use with other NSAIDs or if the patient has a previous history of peptic ulcer disease, and co-prescribing with anti-secretory medications such as proton pump inhibitors. Eradication of Helicobacter pylori has a protective role against developing peptic ulcers and may also improve symptoms of NSAIDs induced dyspepsia.

Shock Index Correlates with Extravasation on Angiographs of Gastrointestinal Hemorrhage: A Logistics Regression Analysis

We applied multivariate analysis to the clinical findings in patients with acute gastrointestinal (GI) hemorrhage and compared the relationship between these findings and angiographic evidence of extravasation. Our study population consisted of 46 patients with acute GI bleeding. They were divided into two groups. In group 1 we retrospectively analyzed 41 angiograms obtained in 29 patients (age range, 25-91 years; average, 71 years). Their clinical findings including the shock index (SI), diastolic blood pressure, hemoglobin, platelet counts, and age, which were quantitatively analyzed. In group 2, consisting of 17 patients (age range, 21-78 years; average, 60 years), we prospectively appliedmore » statistical analysis by a logistics regression model to their clinical findings and then assessed 21 angiograms obtained in these patients to determine whether our model was useful for predicting the presence of angiographic evidence of extravasation. On 18 of 41 (43.9%) angiograms in group 1 there was evidence of extravasation; in 3 patients it was demonstrated only by selective angiography. Factors significantly associated with angiographic visualization of extravasation were the SI and patient age. For differentiation between cases with and cases without angiographic evidence of extravasation, the maximum cutoff point was between 0.51 and 0.0.53. Of the 21 angiograms obtained in group 2, 13 (61.9%) showed evidence of extravasation; in 1 patient it was demonstrated only on selective angiograms. We found that in 90% of the cases, the prospective application of our model correctly predicted the angiographically confirmed presence or absence of extravasation. We conclude that in patients with GI hemorrhage, angiographic visualization of extravasation is associated with the pre-embolization SI. Patients with a high SI value should undergo study to facilitate optimal treatment planning.« less

Purpose: To characterize the prevalence, pathophysiology, and natural history of chronic radiation proctitis 5 years following radiation therapy (RT) for localized carcinoma of the prostate. Methods and Materials: Studies were performed in 34 patients (median age 68 years; range 54-79) previously randomly assigned to either 64 Gy in 32 fractions over 6.4 weeks or 55 Gy in 20 fractions over 4 weeks RT schedule using 2- and later 3-dimensional treatment technique for localized prostate carcinoma. Each patient underwent evaluations of (1) gastrointestinal (GI) symptoms (Modified Late Effects in Normal Tissues Subjective, Objective, Management and Analytic scales including effect on activitiesmore » of daily living [ADLs]); (2) anorectal motor and sensory function (manometry and graded balloon distension); and (3) anal sphincteric morphology (endoanal ultrasound) before RT, at 1 month, and annually for 5 years after its completion. Results: Total GI symptom scores increased after RT and remained above baseline levels at 5 years and were associated with reductions in (1) basal anal pressures, (2) responses to squeeze and increased intra-abdominal pressure, (3) rectal compliance and (4) rectal volumes of sensory perception. Anal sphincter morphology was unchanged. At 5 years, 44% and 21% of patients reported urgency of defecation and rectal bleeding, respectively, and 48% impairment of ADLs. GI symptom scores and parameters of anorectal function and anal sphincter morphology did not differ between the 2 RT schedules or treatment techniques. Conclusions: Five years after RT for prostate carcinoma, anorectal symptoms continue to have a significant impact on ADLs of almost 50% of patients. These symptoms are associated with anorectal dysfunction independent of the RT schedules or treatment techniques reported here.« less

Acta Oncologica Lecture. Gastrointestinal consequences of cancer treatment and the wider context: a bad gut feeling.

PubMed

Muls, Ann Cecile

The percentage of people living with a diagnosis of cancer is rising globally. Between 20% and 25% of people treated for cancer experience a consequence of cancer which has an adverse impact on the quality of their life. Gastrointestinal (GI) symptoms are the most common of all consequences of cancer treatment and have the greatest impact on daily activity. PATHOPHYSIOLOGY OF LONG-TERM BOWEL DAMAGE AFTER PELVIC RADIOTHERAPY: Long-term damage to the bowel after radiotherapy is mediated by ischaemic changes and fibrosis. Each fraction of radiotherapy causes a series of repetitive injuries to the intestinal tissue resulting in an altered healing process, which affects the integrity of the repair and changes the architecture of the bowel wall. THE NATURE OF GI SYMPTOMS THAT DEVELOP: Patient-reported outcome measures show that diarrhoea, urgency, increased bowel frequency, tenesmus and flatulence are the five most prevalent GI symptoms with a moderate or severe impact on patients' daily lives after treatment with pelvic radiotherapy. Many patients also experience fatigue, urinary problems and have sexual concerns. SYSTEMATIC ASSESSMENT AND MANAGEMENT: The complex nature of those symptoms warrants systematic assessment and management. The use of a tested algorithm can assist in achieving this. The most common contributing factors to ongoing bowel problems after pelvic radiotherapy are small intestinal bacterial overgrowth, bile acid malabsorption, pancreatic insufficiency, rectal bleeding and its impact on bone health. Symptom burden, socio-psychosocial impact, memory and cognitive function, fatigue, urinary problems and sexual concerns need to be taken into account when thinking about consequences of cancer treatment. As our understanding of consequences of cancer treatments continues to emerge and encompass a wide variety of specialties, a holistic, multifaceted and multidisciplinary approach is required to manage those consequences long-term.

The aim of the present study was to assess the effectiveness of applying grape seed extract (GSE) gel in periodontal pockets for the treatment of chronic periodontitis. Eighty-six sites with pocket depth (PD) >4 mm were selected from five systemically-healthy patients in whom scaling, and root planing were performed, and oral instructions were given, a week earlier. PD, gingival index (GI), plaque index (PI), and bleeding on probing (BOP) were measured, and sites were then divided into the control group (N = 38) and GSE group (N = 48). Four doses of formulated 2% mucoadhesive GSE gel were applied to GSE group sites at baseline visit (T0), and 3, 6, and 9 days after T0. Similarly, a control gel was applied to the control sites. PD, PI, GI and BOP were re-evaluated after 4 weeks and 6 months of first gel application. Paired t test for both the control and GSE groups showed a significant reduction for all variables after 6 months of gel application (P < .05). The independent t test showed a significant difference (P < .05) only in the reduction of gingival index (mean: 0.85 ± 0.77 for control and 1.3 ± 0.8 for GSE) and plaque index (mean: 0.75 ± 0.71 for control and 1.12 ± 0.7 for GSE). The subgingival application of the formulated 2% mucoadhesive GSE gel showed significant improvement in the PI and GI only. © 2018 John Wiley & Sons Australia, Ltd.

Massive postpartum right renal hemorrhage.

All reported cases of massive postpartum right renal hemorrhage have involved healthy young primigravidas and blacks have predominated (4 of 7 women). Coagulopathies and underlying renal disease have been absent. Hematuria was painless in 5 of 8 cases. Hemorrhage began within 24 hours in 1 case, within 48 hours in 4 cases and 4 days post partum in 3 cases. Our first case is the only report in which hemorrhage has occurred in a primipara. Failure of closure or reopening of pyelovenous channels is suggested as the pathogenesis. The hemorrhage has been self-limiting, requiring no more than 1,500 cc whole blood replacement. Bleeding should stop spontaneously, and rapid renal pelvic clot lysis should follow with maintenance of adequate urine output and Foley catheter bladder decompression. To date surgical intervention has not been necessary.

Duodenal endoscopic resection is the most difficult type of endoscopic treatment in the gastrointestinal tract (GI) and is technically challenging because of anatomical specificities. In addition to these technical difficulties, this procedure is associated with a significantly higher rate of complication than endoscopic treatment in other parts of the GI tract. Postoperative delayed perforation and bleeding are hazardous complications, and emergency surgical intervention is sometimes required. Therefore, it is urgently necessary to establish a management protocol for preventing serious complications. For instance, the prophylactic closure of large mucosal defects after endoscopic resection may reduce the risk of hazardous complications. However, the size of mucosal defects after endoscopic submucosal dissection (ESD) is relatively large compared with the size after endoscopic mucosal resection, making it impossible to achieve complete closure using only conventional clips. The over-the-scope clip and polyglycolic acid sheets with fibrin gel make it possible to close large mucosal defects after duodenal ESD. In addition to the combination of laparoscopic surgery and endoscopic resection, endoscopic full-thickness resection holds therapeutic potential for difficult duodenal lesions and may overcome the disadvantages of endoscopic resection in the near future. This review aims to summarize the complications and closure techniques of large mucosal defects and to highlight some directions for management after duodenal endoscopic treatment. PMID:27547003

Gastrointestinal (GI) hemorrhaging secondary to stomal ulcers following a pancreaticojejunostomy for chronic pancreatitis is a rare postoperative condition that has not hitherto been reported in the literature. A 25-yr-old Japanese female was referred to Ryukyu University Hospital with GI hemorrhaging of unknown origin. She had undergone a modified Puestow procedure (Partington procedure) for chronic pancreatitis with pancreatolithiasis and an associated dilatation of the main pancreatic duct at 19 yr of age. A technetium-99m blood-flow scan demonstrated the pooling of radionuclides in the area of the jejunal loop, which was highly suggestive of bleeding into the jejunum. Over the next day, she demonstrated persistent melena. At exploratory laparotomy, the anastomotic jejunal loop was filled with clotted blood. Operative endoscopy through an incision of the jejunal loop in close proximity to the anastomosis showed oozing blood from the anastomotic jejunal mucosa. Following a resection of the affected anastomotic segment of the jejunum, a side to side longitudinal pancreaticojejunostomy was again performed on this patient. The resected jejunum showed pathologically pseudopolyp-like edema, congestion, and an ulceration of the stomal mucosa. The patient showed a good postoperative course and has been doing well for the past 8 yr since reoperation.

Reality named endoscopic ultrasound biliary drainage

Endoscopic ultrasound (EUS) is used for diagnosis and evaluation of many diseases of the gastrointestinal (GI) tract. In the past, it was used to guide a cholangiography, but nowadays it emerges as a powerful therapeutic tool in biliary drainage. The aims of this review are: outline the rationale for endoscopic ultrasound-guided biliary drainage (EGBD); detail the procedural technique; evaluate the clinical outcomes and limitations of the method; and provide recommendations for the practicing clinician. In cases of failed endoscopic retrograde cholangiopancreatography (ERCP), patients are usually referred for either percutaneous transhepatic biliary drainage (PTBD) or surgical bypass. Both these procedures have high rates of undesirable complications. EGBD is an attractive alternative to PTBD or surgery when ERCP fails. EGBD can be performed at two locations: transhepatic or extrahepatic, and the stent can be inserted in an antegrade or retrograde fashion. The drainage route can be transluminal, duodenal or transpapillary, which, again, can be antegrade or retrograde [rendezvous (EUS-RV)]. Complications of all techniques combined include pneumoperitoneum, bleeding, bile leak/peritonitis and cholangitis. We recommend EGBD when bile duct access is not possible because of failed cannulation, altered upper GI tract anatomy, gastric outlet obstruction, a distorted ampulla or a periampullary diverticulum, as a minimally invasive alternative to surgery or radiology.

Emergency right hepatectomy after laparoscopic tru-cut liver biopsy

PubMed Central

Quezada, Nicolás; León, Felipe; Martínez, Jorge; Jarufe, Nicolás; Guerra, Juan Francisco

2015-01-01

Background Liver biopsy is a common procedure usually required for final pathologic diagnosis of different liver diseases. Morbidity following tru-cut biopsy is uncommon, with bleeding complications generally self-limited. Few cases of major hemorrhage after liver biopsies have been reported, but to our knowledge, no cases of emergency hepatectomy following a tru-cut liver biopsy have been reported previously. Presentation of case We report the case of a 38 years-old woman who presented with an intrahepatic arterial bleeding after a tru-cut liver biopsy under direct laparoscopic visualization, initially controlled by ligation of the right hepatic artery and temporary liver packing. On tenth postoperative day, she developed a pseudo-aneurysm of the anterior branch of the right hepatic artery, evolving with massive bleeding that was not amenable to control by endovascular therapy. Therefore, an emergency right hepatectomy had to be performed in order to stop the bleeding. The patient achieved hemodynamic stabilization, but developed a biliary fistula from the liver surface, refractory to non-operative treatment. In consequence, a Roux-Y hepatico-jejunostomy was performed at third month, with no further complications. Discussion Bleeding following tru-cut biopsy is a rare event. To our knowledge, this is the first report of an emergency hepatectomy due to hemorrhage following liver biopsy. Risks and complications of liver biopsy are revised. Conclusion Care must be taken when performing this kind of procedures and a high level of suspicion regarding this complication should be taken in count when clinical/hemodynamic deterioration occurs after these procedures.

Upper gastrointestinal bleeding (UGIB) is the key emergency situation in clinical endoscopy and is traditionally treated with injection, thermal or through the scope clipping therapy. Mortality rates are in the range of 8-10% and demand new treatment approaches. The Over-The-Scope Clip (OTSC ® ) has been described as a very effective hemostatic device in UGIB. We compared OTSC with the Padlock™ device in an established pre-clinical setting. Our test-bed consisted of the biohybrid EASIE model using soft silicone tubes, tunneled into the gastric wall and surfacing at a mucosa defect, representing the bleeding site. After successful deployment of the OTSC and Padlock devices on the spurting ulcer bleed (Forrest Ia) the vessel tubes were pressurized with a manometer to 120 mmHg. Tight closure at this pressure was defined as successful hemostasis (primary endpoint). N = 11 procedures were done with each device. Statistical testing was done using Fisher's exact test. Sample size was adjusted to an assumed α-error of 5% (two-sided test) and a power of 80%. Technically correct placement of the respective hemostatic device was achieved in all procedures. A statistically significant difference was found in the primary endpoint. In OTSC the success proportion was 100%; 11/11 (95% KI 74.1% to 100%); in Padlock it was 0%; 0/11 (95% KI 0%-25.8%). This means that no bleeding was stopped by Padlock. The mean value of perfusion pressure resistance was 300 mmHg (cut-off) for OTSC and 9.2 ± 8.4 mmHg for Padlock. Our data on hemostatic function of OTSC coincide with the clinical literature and earlier pre-clinical studies in the EASIE model, which is widely accepted as a realistic and effective simulation system for clinical conditions. The inability of Padlock to stop hemorrhage may be due to design differences and, thus, its limitation in providing tight sealing of the clipped tissue. Different types of endoscope-tip mounted clips have different performances. OTSC consistently stops simulated spurting bleeding, Padlock fails to do so. These differences are statistically significant.

Amyloidosis is characterized by the extracellular deposition of amyloid protein in various organs. Gastrointestinal involvement in amyloidosis is common, but a diagnosis of amyloidosis is often delayed. Severe gastrointestinal hemorrhage in amyloidosis is rare but can be fatal in some cases. We experienced a case of a 49-year-old man who presented with recurrent massive hematochezia. Although embolization was performed eight times for bleeding from different sites of the small intestine, hematochezia did not cease. We report the case, with a review of the literature.

Portal hypertensive gastropathy: A systematic review of the pathophysiology, clinical presentation, natural history and therapy

2016-01-01

AIM: To describe the pathophysiology, clinical presentation, natural history, and therapy of portal hypertensive gastropathy (PHG) based on a systematic literature review. METHODS: Computerized search of the literature was performed via PubMed using the following medical subject headings or keywords: “portal” and “gastropathy”; or “portal” and “hypertensive”; or “congestive” and “gastropathy”; or “congestive” and “gastroenteropathy”. The following criteria were applied for study inclusion: Publication in peer-reviewed journals, and publication since 1980. Articles were independently evaluated by each author and selected for inclusion by consensus after discussion based on the following criteria: Well-designed, prospective trials; recent studies; large study populations; and study emphasis on PHG. RESULTS: PHG is diagnosed by characteristic endoscopic findings of small polygonal areas of variable erythema surrounded by a pale, reticular border in a mosaic pattern in the gastric fundus/body in a patient with cirrhotic or non-cirrhotic portal hypertension. Histologic findings include capillary and venule dilatation, congestion, and tortuosity, without vascular fibrin thrombi or inflammatory cells in gastric submucosa. PHG is differentiated from gastric antral vascular ectasia by a different endoscopic appearance. The etiology of PHG is inadequately understood. Portal hypertension is necessary but insufficient to develop PHG because many patients have portal hypertension without PHG. PHG increases in frequency with more severe portal hypertension, advanced liver disease, longer liver disease duration, presence of esophageal varices, and endoscopic variceal obliteration. PHG pathogenesis is related to a hyperdynamic circulation, induced by portal hypertension, characterized by increased intrahepatic resistance to flow, increased splanchnic flow, increased total gastric flow, and most likely decreased gastric mucosal flow. Gastric mucosa in PHG shows increased susceptibility to gastrotoxic chemicals and poor wound healing. Nitrous oxide, free radicals, tumor necrosis factor-alpha, and glucagon may contribute to PHG development. Acute and chronic gastrointestinal bleeding are the only clinical complications. Bleeding is typically mild-to-moderate. Endoscopic therapy is rarely useful because the bleeding is typically diffuse. Acute bleeding is primarily treated with octreotide, often with concomitant proton pump inhibitor therapy, or secondarily treated with vasopressin or terlipressin. Nonselective β-adrenergic receptor antagonists, particularly propranolol, are used to prevent bleeding after an acute episode or for chronic bleeding. Iron deficiency anemia from chronic bleeding may require iron replacement therapy. Transjugular-intrahepatic-portosystemic-shunt and liver transplantation are highly successful ultimate therapies because they reduce the underlying portal hypertension. CONCLUSION: PHG is important to recognize in patients with cirrhotic or non-cirrhotic portal hypertension because it can cause acute or chronic GI bleeding that often requires pharmacologic therapy.

We developed a novel method of endoscopic subserosal dissection (ESSD) for removal of subepithelial tumors (SETs) originating from the muscularis propria (MP) layer in the upper gastrointestinal (GI) tract. The aim of this study was to evaluate the efficacy, safety, and clinical outcome of this method. Eleven patients with upper GI SETs originating from the MP layer were treated by ESSD between October 2016 and March 2017. ESSD technique consists of six major procedures: (1) incising the mucosal and submucosal layer around the lesion and exposing MP layer; (2) continuous injection was performed while the injection needle slowly moved from the MP layer toward the subserosal layer; (3) incising MP layer; (4) subserosal injection was performed to further separate the serosa from the MP layer; (5) the mucosa, submucosa, and MP layer including SET were carefully dissected en bloc; and (6) closure of the gastric-wall defect with endoscopic techniques. Primary outcome including clinical procedural success and procedure-related adverse events were documented. ESSD was successfully performed in 11 patients. The complete resection rate was 100%, and the mean operation time was 51 (range 22-76) min. The mean resected lesion size was 27 (range 15-40) mm. Pathological diagnosis of these lesions included gastrointestinal stromal tumors (8/11), heterotopic pancreas (1/11), hamartoma (1/11), and leiomyoma (1/11). The small perforations occurred in two patients (4 × 4 and 5 × 5 mm, respectively) during the operation. All perforations and defects were closed successfully by endoscopic techniques. No GI bleeding, peritonitis, abdominal abscess, and other adverse events were observed. No lesion residual or recurrence was found during the follow-up period (mean 18 weeks; range 10-29 weeks). ESSD seems to be an efficacious, safe, and minimally invasive treatment for patients with upper GI SETs originating from the MP layer, making it possible to resect deep lesions, provide precise pathological diagnosis, and maintain the integrity of serosa.

ABSTRACT Introduction: Maintenance of good oral hygiene is important for patients undergoing fixed orthodontic treatment. Aim: The aim of this study was to evaluate the effectiveness of a manual orthodontic toothbrush, powered toothbrush with oscillating head and sonic toothbrush in controlling plaque, gingivitis and interdental bleeding in patients undergoing fixed orthodontic treatment, and to compare their relative efficacy. Materials and methods: Sixty subjects, who were to receive orthodontic treatment with both upper and lower fixed appliances, were randomly divided into three study groups, with 20 patients in each group. Groups I to III were given manual orthodontic, powered and sonic toothbrushes, respectively. Plaque index (PI), gingival index (GI) and interdental bleeding index were scored to assess the level of plaque accumulation, gingival health and interdental bleeding at baseline; 4 and 8 weeks recall visits after fixed appliance bonding. Paired t-tests and one-way analysis of variance (ANOVA) tests were used for intragroup and intergroup comparisons. The level of statistical significance was set at p < 0.05. Results: This study showed that a significant reduction in all the three indices scores was found from baseline to 4 and 8 weeks in group III. On intergroup comparison, no statistically significant differences were detected between the three groups for any of the parameters assessed. Conclusion: On intragroup comparison, sonic brushes performed superiorly in reducing gingivitis, plaque and interdental bleeding as compared to the manual orthodontic and powered brushes. On intergroup comparison, the relative comparative effectiveness was found to be similar for all the three brushes. How to cite this article: Sharma R, Trehan M, Sharma S, Jharwal V, Rathore N.

Presacral venous haemorrhage during rectal movement is low, but is often massive, and even fatal. Our objective is the "in vitro" determination of the results of electrocoagulation applied to a fragment of muscle on the sacral bone surface during rectal resection due to a malignant neoplasm of the rectum. Single-pole coagulation was applied "in vitro" with the selector at maximum power on a 2×2 cms muscle fragment, applied to the anterior side of the IV sacral vertebra until reaching boiling point. The method was used on 6 patients with bleeding of the presacral venous plexus. In the "in vitro" study, boiling point was reached in 90 seconds from applying the single-pole current on the muscle fragment. Electrocoagulation was applied to a 2×2 cm rectal muscle fragment in 6 patients with presacral venous haemorrhage, using pressure on the surface of the presacral bone, with the stopping of the bleeding being achieved in all cases. The use of indirect electrocoagulation on a fragment of the rectus abdominis muscle is a straightforward and highly effective technique for controlling presacral venous haemorrhage.

Wilson, Stephen J; Bellamy, Mark C; Giannoudis, Peter V

2005-05-01

Recombinant activated Factor VII (rFVIIa) has been successfully used in the treatment of haemophilia A and B with associated inhibitors for some years. Activated Factor VII binds to activated platelets independently of tissue factor. The resulting stimulation of an exaggerated early thrombin burst at sites of vascular injury makes it an attractive potential treatment for massive, uncontrolled bleeding associated with surgery and trauma. This article describes the evidence relating to surgery and trauma. The lack of large, controlled trials of rFVIIa means that a definitive recommendation regarding its use cannot be made at present. However, in the context of clearly defined protocols and balanced treatment strategies, rFVIIa may have a role in traumatic bleeding. Large scale, randomised controlled trials in trauma are required, as is further work on the safety profile of rFVIIa with an independent international safety monitoring committee.

A 60-year-old woman with massive hemorrhage from duodenal varices was transferred to our hospital for the purpose of transcatheter intervention. Although digital subtraction arterial portography could not depict the entire pathway of collateral circulation, the efferent route of the duodenal varices was clearly demonstrated on subsequent CT during arterial portography. Balloon-occluded retrograde transvenous obliteration (B-RTO) of the varices was performed via the efferent vein and achieved complete thrombosis of the varices.

In trauma research, "massive transfusion" (MT), historically defined as receiving ≥10 units of red blood cells (RBCs) within 24 h of admission, has been routinely used as a "gold standard" for quantifying bleeding severity. Due to early in-hospital mortality, however, MT is subject to survivor bias and thus a poorly defined criterion to classify bleeding trauma patients. Using the data from a retrospective trauma transfusion study, we applied a latent-class (LC) mixture model to identify severely hemorrhaging (SH) patients. Based on the joint distribution of cumulative units of RBCs and binary survival outcome at 24 h of admission, we applied an expectation-maximization (EM) algorithm to obtain model parameters. Estimated posterior probabilities were used for patients' classification and compared with the MT rule. To evaluate predictive performance of the LC-based classification, we examined the role of six clinical variables as predictors using two separate logistic regression models. Out of 471 trauma patients, 211 (45 %) were MT, while our latent SH classifier identified only 127 (27 %) of patients as SH. The agreement between the two classification methods was 73 %. A non-ignorable portion of patients (17 out of 68, 25 %) who died within 24 h were not classified as MT but the SH group included 62 patients (91 %) who died during the same period. Our comparison of the predictive models based on MT and SH revealed significant differences between the coefficients of potential predictors of patients who may be in need of activation of the massive transfusion protocol. The traditional MT classification does not adequately reflect transfusion practices and outcomes during the trauma reception and initial resuscitation phase. Although we have demonstrated that joint latent class modeling could be used to correct for potential bias caused by misclassification of severely bleeding patients, improvement in this approach could be made in the presence of time to event data from prospective studies.

Massive spontaneous choroidal hemorrhage in a patient with chronic renal failure and coronary artery disease treated with Plavix.

To report a case of massive spontaneous choroidal hemorrhage in a patient with chronic renal failure and coronary artery disease treated with clopidogrel bisulfate (Plavix). Case report. A 75-year-old man presented with pain and loss of vision in the left eye for 1 week. His medical history was remarkable for systemic hypertension, chronic renal failure, and artery coronary disease. For 6 months, he had been taking 75 mg/day of Plavix after coronary angioplasty. Ocular examination revealed the patient to be in angle closure. Ultrasonography and computed tomography scan revealed a massive choroidal hemorrhage pushing the iris-lens diaphragm forward. Pain and intraocular pressure were treated successfully with evacuative sclerotomies, but the final exitus after 6 months was bulbar phthisis. Massive spontaneous choroidal hemorrhage is an extremely rare event that usually has been described in older patients (65-87 years old) receiving anticoagulants or thrombolytic agents. Systemic hypertension, generalized atherosclerosis, and age-related macular degeneration are additional risk factors. In the present case, massive choroidal hemorrhage was associated with use of clopidogrel bisulfate (Plavix) in a patient with chronic renal failure. Our report indicates that Plavix should be administered with caution in patients with chronic renal failure owing to the risk of serious choroidal bleeding. Chronic renal failure should be also included in the list of risk factors for massive spontaneous choroidal hemorrhage. Evacuative sclerotomies may have value in the relief of pain and elevated intraocular pressure but has not been shown to be beneficial in visual and anatomic outcomes.

Both irritable bowel syndrome (IBS) and patent foramen ovale (PFO) have a similar prevalence in the general population, affect more commonly women and are related to comorbidities such as migraine. In IBS there are alterations in the metabolism of certain substances like serotonin. In the presence of PFO with a right- to left-shunt (RLS), a percentage of venous blood bypasses the lung filter and may increase these substances in blood. A phone interview was done to determine the presence of IBS in patients previously attended for detection of RLS with transcranial Doppler ultrasound. The presence and grade of RLS was analyzed and compared with subjects without gastrointestinal symptoms (NoGI). Rome II criteria were used to diagnose IBS or other functional gastrointestinal disorder (FGD) and Venice 1999 consensus were used for the diagnosis of RLS. Thirthy-three (18.3%) of 180 interviewed patients had IBS and 62 (34.4%) other FGD. RLS was found in 41% of NoGI patients, 64% of patients with IBS and 68% of patients with other FGD (odds ratio [OR] = 2.56; p < 0.05 for SII, and OR = 3.06; p < 0.01 for other FGD). RLS with a massive pattern was registered in en 27% of NoGI patients, 39% of patients with IBS and 45% of patients with other FGD (OR = 1.73; p = 1 for IBS, and OR = 2.21; p < 0.05 for other FGD). We found a higher prevalence of cardiac RLS through a PFO in patients with IBS and other FGD. A possible etiopathogenic relationship must be considered in future studies.

Given that tobacco smoking habit is a risk factor for periodontal diseases, the aim of this study was to compare clinical periodontal aspects between smokers and non-smokers. The clinical status were assessed in 55 patients, 29 smokers and 26 non-smokers, aged 30 to 50 years, with mean age of 40. The clinical parameters used were: probing depth (PD), plaque index (PI), gingival index (GI), clinical attachment level (CAL), gingival recession (GR) and gingival bleeding index (GBI) for arches (upper and lower) and teeth (anterior and posterior). Tooth loss was also evaluated in both groups. Multiple regression analysis showed: tendency of greater probing depth and clinical attachment level means for smokers; greater amount of plaque in smokers in all regions; greater gingival index means for non-smokers with clinical significance (p<0.05) in all regions. Although, without statistical significance, the analysis showed greater gingival bleeding index means almost always for non-smokers; similar gingival recession means in both groups and tendency of upper tooth loss in smokers and lower tooth loss in non-smokers. The findings of this study showed that clinical periodontal parameters may be different in smokers when compared to non-smokers and that masking of some periodontal signs can be a result of nicotine's vasoconstrictor effect.

The resuscitative endovascular balloon occlusion of the aorta, because of its efficacy and feasibility, has been widely used in treating patients with severe torso trauma. However, complications developing around the site proximal to the occlusion by resuscitative endovascular balloon occlusion of the aorta have almost never been studied. A 50-year-old Japanese woman fell from a height of approximately 10 m. At initial arrival, her respiratory rate was 24 breaths/minute, her blood oxygen saturation was 95% under 10 L/minute oxygenation, her pulse rate was 90 beats per minute, and her blood pressure was 180/120 mmHg. Mild lung contusion, hemopneumothorax, unstable pelvic fracture, and retroperitoneal bleeding with extravasation of contrast media were observed in initial computed tomography. As her vital signs had deteriorated during computed tomography, a 7-French aortic occlusion catheter (RESCUE BALLOON®, Tokai Medical Products, Aichi, Japan) was inserted and inflated for aortic occlusion at the first lumbar vertebra level and transcatheter arterial embolization was performed for the pelvic fracture. Her bilateral internal iliac arteries were embolized with a gelatin sponge; however, the embolized sites presented recanalization as coagulopathy appeared. Her bilateral internal iliac arteries were re-embolized by n-butyl-2-cyanoacrylate. The balloon was deflated 18 minutes later. After embolization, repeat computed tomography was performed and a massive hemothorax, which had not been captured on arrival, had appeared in her left pleural cavity. Thoracotomy hemostasis was performed and a hemothorax of approximately 2500 ml was aspirated to search for the source of bleeding. However, clear active bleeding was not captured; resuscitative endovascular balloon occlusion of the aorta may have been the cause of the increased bleeding of the thoracic injury at the proximal site of the aorta occlusion. It is necessary to note that the use of resuscitative endovascular balloon occlusion of the aorta may increase bleeding in sites proximal to occlusions, even in the case of minor injuries without active bleeding at the initial diagnosis.

Abdominal blunt trauma is the main cause of death in people younger than 40 years old. The liver injury still represents a challenging problem. Isolated hepatic injury is rare and it occurs more frequentely in polytraumatizated patients and causes massive haemoperitoneum. The Authors report a case of a 83 years-old woman admitted to Emergency Department for syncope due to an active bleeding arising from a rupture of a right hepatic lobe unsuspected tumor. The computer tomography (CT) scans showed a clear pattern of liver laceration of the VI segment with contrast enhancement spreading in the surrounding tissues, and detected a multifocal hepatocarcinoma located in the VI, VII and VIII segments. Patient's haemodinamically unstable conditions suggested an urgent laparotomy. An accurate perihepatic packing with sterile-drape were successfully employed to control liver hemorrage. Temporary abdominal closure, followed by hepatic arteriography and the right hepatic artery embolization, completed the damage control. Re-exploration laparotomy after 72 hours confirmed the definitive haemostasis and the pack removal was performed without complications. CT plays a leading role in the diagnosis of liver damage. The patient's haemodynamic status is the principal criterion determining conservative or operative therapy in blunt liver injury. The early perihepatic packing followed by artheriographic embolization to stop liver hemorrhage showed efficacy and safety for the patient. The packing performed with sterile-drape is able to avoid removal complications and 72 hours timing for the pack removal is effective to avoid re-bleeding.

Introduction. To identify factors that determine blood loss during peripartum hysterectomy for abnormally invasive placenta (AIP-hysterectomy). Methods. We reviewed all of the medical charts of 11,919 deliveries in a single tertiary perinatal center. We examined characteristics of AIP-hysterectomy patients, with a single experienced obstetrician attending all AIP-hysterectomies and using the same technique. Results. AIP-hysterectomy was performed in 18 patients (0.15%: 18/11,919). Of the 18, 14 (78%) had a prior cesarean section (CS) history and the other 4 (22%) were primiparous women. Planned AIP-hysterectomy was performed in 12/18 (67%), with the remaining 6 (33%) undergoing emergent AIP-hysterectomy. Of the 6, 4 (4/6: 67%) patients were primiparous women. An intra-arterial balloon was inserted in 9/18 (50%). Women with the following three factors significantly bled less in AIP-hysterectomy than its counterpart: the employment of an intra-arterial balloon (4,448 ± 1,948 versus 8,861 ± 3,988 mL), planned hysterectomy (5,003 ± 2,057 versus 9,957 ± 4,485 mL), and prior CS (5,706 ± 2,727 versus 9,975 ± 5,532 mL). Patients with prior CS (−) bled more: this may be because these patients tended to undergo emergent surgery or attempted placental separation. Conclusion. Patients with intra-arterial balloon catheter insertion bled less on AIP-hysterectomy. Massive bleeding occurred in emergent AIP-hysterectomy without prior CS. PMID:27630716

The aim of the present study was to evaluate the clinical and microbiological effect of systemic levofloxacin (LFX) as an adjunct to scaling and root planing (SRP) in patients with chronic periodontitis (CP). Sixty-five patients with CP were randomly divided into a test (n = 33, SRP and LFX 500 mg, once daily [o.d.]) and a control group (n = 32, SRP and placebo, o.d.). Plaque index (PI), gingival index (GI), percentage of sites with bleeding on probing (%BoP), probing depth (PD), and clinical attachment level (CAL) were recorded at baseline, 10 days, and 1-, 3-, and 6-month intervals. The percentage of sites positive for Aggregatibacter actinomycetemcomitans (A. actinomycetemcomitans), Porphyromonas gingivalis, and Tannerella forsythia were recorded at baseline and at 3 and 6 months. Patients receiving LFX showed statistically-significant improvements in mean PD and CAL. The intergroup difference in PI, GI, and%BoP was not significant at any interval. There was a reduction in the percentage of sites positive for periodontopathic bacteria over the duration of the study in both groups, and a statistically-significant reduction in the number of sites positive for A. actinomycetemcomitans in the LFX group (P < 0.001). Levofloxacin was found to significantly improve the clinical and microbiological parameters in CP individuals. © 2014 Wiley Publishing Asia Pty Ltd.

Wireless capsule endoscopy (WCE) is a powerful tool for medical screening and diagnosis, where a small capsule is swallowed and moved by means of natural peristalsis and gravity through the human gastrointestinal (GI) tract. The camera-integrated capsule allows for visualization of the small intestine, a region which was previously inaccessible to classical flexible endoscopy. As a diagnostic tool, it allows to localize the sources of bleedings in the middle part of the gastrointestinal tract and to identify diseases, such as inflammatory bowel disease (Crohn's disease), polyposis syndrome, and tumors. The screening and diagnostic efficacy of the WCE, especially in the stomach region, is hampered by a variety of technical challenges like the lack of active capsular position and orientation control. Therapeutic functionality is absent in most commercial capsules, due to constraints in capsular volume and energy storage. The possibility of using body-exogenous magnetic fields to guide, orient, power, and operate the capsule and its mechanisms has led to increasing research in Magnetically Guided Capsule Endoscopy (MGCE). This work shortly reviews the history and state-of-art in WCE technology. It highlights the magnetic technologies for advancing diagnostic and therapeutic functionalities of WCE. Not restricting itself to the GI tract, the review further investigates the technological developments in magnetically guided microrobots that can navigate through the various air- and fluid-filled lumina and cavities in the body for minimally invasive medicine. © 2017 American Association of Physicists in Medicine.

Transjugular intrahepatic portosystemic shunting (TIPS) is an effective treatment modality for refractory variceal bleeding and ascites in patients with cirrhotic portal hypertension (CPH). Variceal rebleeding and shunt dysfunction are major post-TIPS morbidities. This study aimed to retrospectively evaluate the effectiveness and safety of use of concomitant variceal embolization and prophylactic antiplatelet/anticoagulative in patients with CPH undergoing TIPS. Between October 2006 and October 2011, 182 patients with CPH were retrospectively and consecutively hospitalized for elective TIPS with Fluency stenting. Concomitant variceal embolization was given after establishing the shunt. Subcutaneous heparin was given after TIPS and replaced by oral clopidogrel, aspirin, or warfarin for at least 6 months. Main outcome measures included shunt patency rate, recurrence of CPH (rebleeding and/or refractory ascites), hepatic encephalopathy (HE) frequency, and post-TIPS survival. The cumulative primary patency rate was 96%, 94%, 90%, 88%, and 88% at 6, 12, 24, 36, and 48 months, respectively. Shunt stenosis occurred in 16 (9%) patients, gastrointestinal (GI) rebleeding in 32 (17.5%) patients, recurrence of refractory ascites 44 (48%) patients, HE in 42 (23%) patients, and death in 36 (20%) patients during the follow-up period. Use of concomitant variceal embolization and prophylactic antiplatelet/anticoagulative was associated with a favorable shunt patency and a low risk of GI rebleeding.

Objectives. This study aimed to investigate the efficacy of a Schinus terebinthifolius (ST) mouthwash in reducing gingival inflammation levels (GI) and biofilm accumulation (BA) in children with gingivitis. Methods. This was a randomized, controlled, triple blind, and phase II clinical trial, with children aged 9–13 years (n = 27) presenting with biofilm-induced gingivitis. The sample was randomized into experimental (0.3125% ST, n = 14) and control (0.12% chlorhexidine/CHX, n = 13) groups. Products were masked as regards color, flavor and aroma. Intervention protocol consisted in supervised rinsing of 10 mL/day for 01 minute for 10 days. Gingival bleeding and simplified oral hygiene indexes were used to assess the efficacy variables, measured at baseline and after intervention by calibrated examiners. Data were statistically treated with paired t-test, unpaired t-test, and Wilcoxon and Mann-Whitney tests (α = .05). Results. It was found that both ST and CHX were able to significantly reduce GI levels after 10 days (P < 0.001) and there was no significant difference between them (P > 0.05). CHX was the only product able to significantly reduce BA after 10 days when compared to baseline (P < 0.05). Conclusion. ST mouthwash showed significant anti-inflammatory activity (equivalent to CHX), but it was not able to reduce biofilm accumulation. PMID:23843886

Endoscopic submucosal dissection (ESD) can remove early stage GI tumors of various sizes en bloc; however, success requires reducing the relatively high postprocedure bleeding rate. The aim of this study was to assess the safety and efficacy of a novel, fully synthetic, and self-assembled peptide solution that functions as an extracellular matrix scaffold material to facilitate reconstruction of normal tissues in ESD-induced ulcers. Consecutive patients who underwent gastric ESD were prospectively enrolled. Immediately after the resection, the solution was applied to the site with a catheter. Gastric ulcers were evaluated by endoscopy and classified as active, healing, or scarring stages at weeks 1, 4, and 8 after ESD. Forty-seven patients with 53 lesions, including 14 (29.8%) previously on antithrombotic therapy and 2 (4.3%) requiring heparin bridge therapy, were analyzed; 2 patients were excluded, 1 with perforations and 1 with persistent coagulopathy. The mean size of the en bloc resected specimens was 36.5 ± 11.3 mm. The rate of post-ESD bleeding was 2.0% (1/51; 95% CI, 0.03-10.3). Transitional rate to the healing stage of ESD-induced ulcers at week 1 was 96% (49/51). Subsequent endoscopies demonstrated the scarring stage in 19% (9/48) and 98% (41/42) at weeks 4 and 8, respectively. No adverse effects related to this solution occurred. The use of this novel peptide solution may potentially aid in reducing the delayed bleeding rate by promoting mucosal regeneration and speed of ulcer healing after large endoscopic resections in the stomach. Further studies, particularly randomized controlled studies, are needed to fully evaluate its efficacy. ( 000011548.). Copyright © 2016 American Society for Gastrointestinal Endoscopy.

AIM: To evaluate the clinical results of angiography and embolization for massive gastrointestinal hemorrhage after abdominal surgery. METHODS: This retrospective study included 26 patients with postoperative hemorrhage after abdominal surgery. All patients underwent emergency transarterial angiography, and 21 patients underwent emergency embolization. We retrospectively analyzed the angiographic features and the clinical outcomes of transcatheter arterial embolization. RESULTS: Angiography showed that a discrete bleeding focus was detected in 21 (81%) of 26 patients. Positive angiographic findings included extravasations of contrast medium (n = 9), pseudoaneurysms (n = 9), and fusiform aneurysms (n = 3). Transarterial embolization was technically successful in 21 (95%) of 22 patients. Clinical success was achieved in 18 (82%) of 22 patients. No postembolization complications were observed. Three patients died of rebleeding. CONCLUSION: The positive rate of angiographic findings in 26 patients with postoperative gastrointestinal hemorrhage was 81%. Transcatheter arterial embolization seems to be an effective and safe method in the management of postoperative gastrointestinal hemorrhage. PMID:24187463

Non-steroidal anti-inflammatory drug (NSAID)-induced small bowel injury is a topic that deserves attention since the advent of capsule endoscopy and balloon enteroscopy. NSAID enteropathy is common and is mostly asymptomatic. However, massive bleeding, stricture, or perforation may occur. The pathogenesis of small intestine injury by NSAIDs is complex and different from that of the upper gastrointestinal tract. No drug has yet been developed that can completely prevent or treat NSAID enteropathy. Therefore, a long-term randomized study in chronic NSAID users is needed. PMID:22180706

Video capsule endoscopy (VCE) is a procedure that uses a wireless camera to take pictures of the gastrointestinal (GI) tract. A wireless motility capsule (WMC) of a similar size has been developed, which measures pH, pressure, and temperature and can be used to assess regional and total GI transit times. VCE could also potentially be used as a tool for measuring small bowel transit time (SBTT). This study was designed to obtain SBTT from VCE and compare it with historical data generated by WMC. Gastric transit time (GTT) was also measured. Patients were included if the indication for VCE was either iron deficiency anemia (IDA) or overt obscure GI bleed (OOGIB), and they did not have any known motility disorder. Results from VCE were also compared in diabetic vs. non-diabetic patients. There were a total of 147 VCE studies performed, including 42 for OOGIB and 105 for IDA. Median GTT and SBTT were 0.3 and 3.6 h, respectively. The overall median GTT and SBTT were 0.3 and 3.6 h, respectively, in the IDA group compared with 0.3 and 3.4 h in the OOGIB group. When compared with WMC, the GTT and SBTT were significantly faster in both groups (GTT: 3.6 h and SBTT: 4.6 h). The median GTT and SBTT were not significantly different in diabetics vs. non-diabetics [GTT: 17.5 vs. 18.0 min (P = 0.86) and SBTT: 3.9 h (237 min) vs. 3.8 h (230 min), respectively (P = 0.90)]. SBTT as measured using VCE is not significantly different in OOGIB compared with IDA. Both GTT and SBTT are significantly faster as assessed by VCE, which is initiated in the fasting state, compared with WMC measurement, which is initiated after a standard meal. In summary, VCE could potentially be used for measuring SBTT in the fasting state.

To determine the magnitude of cloxacillin loss during surgical procedures involving significant blood loss and high fluid replacement, we compared the pharmacokinetics of cloxacillin in children during craniomaxillofacial surgery with the disposition of the drug in healthy young adult volunteers with intact circulation. Blood loss during craniofacial operations may exceed blood volume, in some cases by as much as three times. Hemodynamic replacement with electrolyte solutions and blood products, which do not contain the drug, further dilute cloxacillin concentrations. In the patients that we studied, mean drug loss was estimated at 71%. Cloxacillin concentrations in serum fell below the lower range of the MIC for Staphylococcus aureus during significant portions of the surgical procedures. Thus, the traditional dosing of cloxacillin during prolonged operations with massive blood loss is inadequate. A more frequent dosing interval or priming of all replacement fluids with the drug may be required to maintain therapeutic levels. Our findings suggest that massive blood loss is likely to have a dramatic effect on the level of any drug with a small distribution volume. If such a drug is essential to the patient's well-being (e.g., antibiotics, antiarrhythmics, and anticonvulsants), it must be replaced promptly. PMID:2393274

Sclerotherapy and endoscopic esophageal variceal ligation (EVL) are commonly used to treat and prevent variceal bleeding. As of today, there has been no report on an unexpected incarceration of a varix hooked on with the bands from the endoscopic EVL device. We recently experienced this emergency while using the 7-band ring endoscopic EVL device (Boston Scientific Corp., Boston, MA) for prophylaxis of variceal bleeding. In this case, the varix body itself was accidently incarcerated in the crevice of the esophageal endoscope after highly negative pressure of absorption was applied on the endoscope. In this situation, using force to take out the gastroscope was not an option as it would tear the vein and cause massive hemorrhage. We were managed to ligate the varix with rubber bands while releasing the incarceration. We observed that ligation of the varix at the same position using all seven ligation bands resulted in disappearance of the targeted varix. The surrounding esophageal mucosa became smooth after the treatment. PMID:25550983

Vaginal metastasis from organs other than the uterus is rare. Generally, patients with vaginal metastasis from colorectal cancer have a dismal prognosis. Although biopsy is the best method to make the diagnosis, massive bleeding may occur. On the other hand, liquid-based cytology (LBC) has the utility to perform immunocytochemistry on additional unstained slides: we can make a diagnosis with several immunocytochemical findings. A 67-year-old postmenopausal female presented to our hospital with vaginal bleeding. The patient had undergone colectomy because of her stage III sigmoid colon cancer 3 years earlier. The patient had also undergone hysterectomy for cervical cancer 30 years earlier. LBC from the vaginal stump revealed adenocarcinoma. Immunocytochemically, cancer cells were negative for cytokeratin 7 and positive for cytokeratin 20, which suggested metastasis from the sigmoid colon cancer; the diagnosis was made without a biopsy. When the patient has a metastatic lesion from colon adenocarcinoma, LBC with immunocytochemistry is useful in making a diagnosis. Copyright © 2012 S. Karger AG, Basel.

Embolization of Acute Nonvariceal Upper Gastrointestinal Hemorrhage Resistant to Endoscopic Treatment: Results and Predictors of Recurrent Bleeding

Acute nonvariceal upper gastrointestinal (UGI) hemorrhage is a frequent complication associated with significant morbidity and mortality. The most common cause of UGI bleeding is peptic ulcer disease, but the differential diagnosis is diverse and includes tumors; ischemia; gastritis; arteriovenous malformations, such as Dieulafoy lesions; Mallory-Weiss tears; trauma; and iatrogenic causes. Aggressive treatment with early endoscopic hemostasis is essential for a favorable outcome. However, severe bleeding despite conservative medical treatment or endoscopic intervention occurs in 5-10% of patients, requiring surgery or transcatheter arterial embolization. Surgical intervention is usually an expeditious and gratifying endeavor, but it can be associated with high operativemore » mortality rates. Endovascular management using superselective catheterization of the culprit vessel, < sandwich> occlusion, or blind embolization has emerged as an alternative to emergent operative intervention for high-risk patients and is now considered the first-line therapy for massive UGI bleeding refractory to endoscopic treatment. Indeed, many published studies have confirmed the feasibility of this approach and its high technical and clinical success rates, which range from 69 to 100% and from 63 to 97%, respectively, even if the choice of the best embolic agent among coils, cyanaocrylate glue, gelatin sponge, or calibrated particles remains a matter of debate. However, factors influencing clinical outcome, especially predictors of early rebleeding, are poorly understood, and few studies have addressed this issue. This review of the literature will attempt to define the role of embolotherapy for acute nonvariceal UGI hemorrhage that fails to respond to endoscopic hemostasis and to summarize data on factors predicting angiographic and embolization failure.« less

This paper evaluates the practice of fresh frozen plasma (FFP) transfusion at the University Hospital, Kuala Lumpur, and analyses its usage by the various clinical departments. The aim of this study is to identify where it is inappropriately used and the clinical indications in which such misuse is common. A retrospective analysis of the blood bank request forms and work sheets during a 6-month period between January 1998 and June 1998 formed the basis of this study. Overall, 40% of 2665 units transfused were considered appropriate. However, out of the 931 episodes of FFP transfusions only 31% were for appropriate indications. The average FFP requirement when used for appropriate indication was about 4 units per episode, whereas for inappropriate indication it was 2.5 units per episode. Inappropriate use in terms of the number of units was highest by the surgical services (68%) and Orthopaedics (64%), while the Department of Paediatrics had the lowest incidence of inappropriate use (40%). When Paediatrics was used as the benchmark, the incidence of inappropriate use by other departments was significantly higher (p < 0.01). As for FFP usage in common clinical indications, there was a high incidence of inappropriate use in burns (82%), perioperative period (73%), cardiac surgery (68%), massive bleeding (62%) and trauma (60%). The findings in this study, specifically the use of FFP for volume support in trauma, massive bleeding and burns, routine requests without identified indication in cardiac bypass surgery, and prophylactic use in the perioperative period can be the basis for recommendations to minimize the inappropriate use of FFP in the future.

Portal hypertension induces collateral shunt formation between the portal and systemic circulation, decompressing the elevated portal pressure. Ectopic varices outside of the gastroesophageal region, such as jejunal varices, are rare conditions. This report describes the successful embolization of ruptured jejunal varices resulting from an extrahepatic portal obstruction. A 62-year-old man was admitted to our hospital with recurrent massive gastrointestinal bleeding. Fourteen months earlier, he had undergone a choledochojejunostomy and pancreatic cystojejunostomy for bile duct stenosis with an enlarged pancreatic pseudocyst due to severe chronic pancreatitis. Contrast-enhanced computed tomography showed jejunal intramural dilated vessels close to the choledochojejunal anastomosis, but extravasation was not observed. Due to the lack of a rapid definitive diagnosis, the patient required massive blood transfusions. Hemorrhagic scintigraphy using 99m Tc-HSAD finally identified the site of the hemorrhage. Angiography and double-balloon endoscopy revealed the anastomotic jejunal varices to be the result of an extrahepatic portal obstruction. Laparotomic transcatheter variceal embolization with microcoils was successful in halting the refractory gastrointestinal bleeding. This surgery preserved hepatopetal portal venous flow by another route, and no complications were observed. At present, 4 years post-surgery, there has been no recurrence of gastrointestinal hemorrhage. The development of jejunal varices is often associated with postoperative adhesions. Some patients with a history of hepatico- or choledochojejunostomy may experience portal hypertension resulting from extrahepatic portal obstruction, leading to the formation of jejunal varices as hepatopetal portal collaterals. The choice of therapy in each patient should be based on the individual hemodynamics of the ectopic varices.

To report the feasibility, complications, and outcomes of emergency extracorporeal life support (ECLS) in refractory cardiac arrests in medical intensive care unit (ICU). Prospective cohort study in the medical ICU in a university hospital in collaboration with the cardiosurgical team of a neighboring hospital. Seventeen patients (poisonings: 12/17) admitted over a 2-year period for cardiac arrest unresponsive to cardiopulmonary resuscitation (CPR) and advanced cardiac life support, without return of spontaneous circulation. ECLS femoral implantation under continuous cardiac massage, using a centrifugal pump connected to a hollow-fiber membrane oxygenator. Stable ECLS was achieved in 14 of 17 patients. Early complications included massive transfusions (n=8) and the need for surgical revision at the cannulation site for bleeding (n=1). Four patients (24%) survived at medical ICU discharge. Deaths resulted from multiorgan failure (n=8), thoracic bleeding(n=2), severe sepsis (n=2), and brain death (n=1). Massive hemorrhagic pulmonary edema during CPR (n=5) and major capillary leak syndrome (n=6) were observed. Three cardiotoxic-poisoned patients (18%, CPR duration: 30, 100, and 180 min) were alive at 1-year follow-up without sequelae. Two of these patients survived despite elevated plasma lactate concentrations before cannulation (39.0 and 20.0 mmol/l). ECLS was associated with a significantly lower ICU mortality rate than that expected from the Simplified Acute Physiology Score II (91.9%) and lower than the maximum Sequential Organ Failure Assessment score (>90%). Emergency ECLS is feasible in medical ICU and should be considered as a resuscitative tool for selected patients suffering from refractory cardiac arrest.

Probiotics act as a unique approach to maintaining oral health by supplementing the endogenous oral bacteria with additional naturally occurring beneficial microbes to provide defense against pathogens harmful to teeth and gingiva. The aim of this pilot study was to clinically evaluate the effects of probiotics on plaque accumulation and gingival inflammation in subjects with fixed orthodontics. The pilot study was comprised of 15 healthy patients, aged 11 to 18 years, undergoing fixed orthodontic treatment. Patients used an all-natural, dissolving lozenge containing six proprietary probiotic strains (Dentaq® Oral and ENT Health Probiotic Complex)for 28 days. Gingival Index (GI) according to Löe-Silness and Plaque Index (PI) according to Quigley-Hein for all teeth were measured at baseline (Day Zero) and at the end of the probiotic regimen (Day 28). The mean baseline GI and PI scores within each patient decreased by 28.4% and 35.8%, respectively, by Day 28. Patients reported decreased tooth and gingival pain, decreased oral bleeding, and increased motivation to maintain proper oral hygiene over the course of the study. This pilot study provided preliminary support for the use of Dentaq Oral and ENT Health Probiotic Complex as a safe and effective natural health product for the reduction of plaque accumulation and gingival inflammation. The results demonstrate its potential therapeutic value and open the door for larger scale placebo-controlled clinical studies to verify these findings.

The aim of this study has been to compare the clinical and radiographic outcome of periodontal intrabony defect treatment by open flap debridement alone or in combination with nanocrystalline hydroxyapatite bone substitute application. Thirty patients diagnosed with advanced periodontits were divided into two groups: the control group (OFD), in which an open flap debridement procedure was performed and the test group (OFD+NHA), in which defects were additionally filled with nanocrystalline hydroxyapatite bone substitute material. Plaque index (PI), gingival index (GI), bleeding on probing (BOP), pocket depth (PD), gingival recession (GR) and clinical attachment level (CAL) were measured prior to, then 6 and 12months following treatment. Radiographic depth and width of defects were also evaluated. There were no differences in any clinical and radiographic parameters between the examined groups prior to treatment. After treatment, BOP, GI, PD, CAL, radiographic depth and width parameter values improved statistically significantly in both groups. The PI value did not change, but the GR value increased significantly after treatment. There were no statistical differences in evaluated parameters between OFD and OFD+NHA groups 6 and 12months after treatment. Within the limits of the study, it can be concluded that the additional use of nanocrystalline hydroxyapatite bone substitute material after open flap procedure does not improve clinical and radiographic treatment outcome.

Although there are studies evaluating the effects of periodontal health on chronic obstructive pulmonary disease (COPD), the effects of COPD - a systemic disease, on periodontal tissue is unknown. The aim of this study is to evaluate the effects of COPD on periodontal tissues by comparing COPD patients and controls. Fifty-two COPD patients and 38 non-COPD controls were included in this case-control study. Number of teeth, plaque index (PI), gingival index (GI), bleeding on probing, clinical attachment level and probing depth were included in the periodontal examination. In addition to clinical evaluations, gingival crevicular fluid (GCF) levels of high-sensitive C-reactive protein (hs-CRP), interleukin-1 beta (IL-lb) and prostaglandin-E2 (PGE2), and serum hs-CRP levels were measured in COPD patients and the controls. The number of teeth was significantly lower while PI and GI were significantly higher in COPD patients when compared to the controls. As well as serum hs-CRP levels, the GCF levels of hs-CRP, IL-1b and PGE2 were significantly higher in COPD patients than the controls. Our results demonstrated that COPD may be associated with periodontal disease as manifested by lower number of teeth and higher levels of inflammatory mediators especially CRP in GCF. This finding may be a reflection of systemic effects of COPD on periodontal tissues. Poor oral health behavior of COPD patients have to be considered in larger size group studies in the future.

Sheetada is the early stage of periodontal diseases. This occurs due to negligence of oral hygiene, changing life-style, habits, and addictions. It is Kapha Rakta Pradhana Vyadhi. In modern dentistry papillary or marginal gingivitis can be correlated with Sheetada, on the basis of similarities in symptoms, involvement of anatomical structure, etiology and prognosis. The epidemiological studies conducted by American Academy of Periodontology shows that gingivitis of varying severities is nearly universal. It is estimated that over 80% of the world's population suffers from gingivitis. In this clinical study, 106 patients were registered among them 103 completed the treatment and were randomly divided by lottery method into two groups. In Group-A, Dashana Samskara paste local application on gums and in Group-B, Dashana Samskara Choorna Pratisarana on gums was given. After enrollment of the patients in the study cardinal symptoms of Sheetada (gingivitis) such as, Raktasrava, Krishnata, Prakledata, Mriduta, Mukhadaurgandhya, and also the objective criteria such as oral hygiene index, Gingival Index (GI-S), and Gingival Bleeding Index (GBI-S) were studied before and after the treatment. While considering comparative effect on subjective parameters such as Raktasrava, Dantamamsa Shiryamanata, Shotha and Chalata statistically significant results were obtained in Group-A than Group-B. In objective parameters such as, GI-S and GBI-S also showed statistically significant results in Group-A. Observations in follow-up study confirmed that the recurrence rate in the Group-Awas significantly lesser than the Group-B. PMID:24049407

Portal hypertension is a common pathology in childhood and one of its most common causes is cavernomatosis of the portal vein. This obstruction causes hemodynamic changes which lead to splenomegaly and collateral circulation. Esophageal varices are one of the most important sequelae, which endanger the patient's life because of a bleeding tendency. Ecosonography helps to detect the thickening of the lesser omentum vis a vis the aortic diameter, caused by the collateral circulation. We studied 15 children presenting with portal hypertension resulting from portal vein cavernomatosis; we performed an upper GI endoscopy and abdominal ecosonography. The endoscopy revealed grade II esophageal varices in 20% of cases, the remaining 80% had grade III and grade IV. Ecosonography revealed an increased lesser omentum/aorta ratio in children with portal hypertension, compared to controls (p < 0.001). Our results suggest that the lesser omentum/aorta ratio has diagnostic value in pediatric portal hypertension.

Thromboembolic events are one of the leading causes of maternal death during the postpartum period. Postpartum thrombolytic therapy with recombinant tissue plasminogen activator (rt-PA) is controversial because the treatment may lead to massive bleeding. Data centralization may be beneficial for analyzing the safety and effectiveness of systemic thrombolysis during the early postpartum period. We performed a computerized MEDLINE and EMBASE search. We collected data for 13 cases of systemic thrombolytic therapy during the early postpartum period, when limiting the early postpartum period to 48 hours after delivery. Blood transfusion was necessary in all cases except for one (12/13; 92%). In seven cases (7/13; 54%), a large amount of blood was required for transfusion. Subsequent laparotomy to control bleeding was required in five cases (5/13; 38%), including three cases of hysterectomy and two cases of hematoma removal, all of which involved cesarean delivery. In cases of transvaginal delivery, there was no report of laparotomy. The occurrence of severe bleeding was high in relation to cesarean section, compared with vaginal deliveries. Using rt-PA in relation to cesarean section might be worth avoiding. However, the paucity of data in the literature makes it difficult to assess the ultimate outcomes and safety of this treatment. © 2017 Nordic Federation of Societies of Obstetrics and Gynecology.

Safe pulmonary vessel sealing device plays a crucial role in anatomic lung resection. In 2014, we reported high rates of massive bleeding complications during transumbilical lobectomy in a canine model due to difficulty in managing the pulmonary vessel with an endostapler. In this animal survival series, we aimed to evaluate the outcome of pulmonary vessel sealing with an electrocautery device to simplify the transumbilical thoracic surgery. Under general anesthesia, a 3-cm longitudinal incision was made over the umbilicus. Under video guidance, a bronchoscope was inserted through the incision for exploration. The diaphragmatic wound was created with an electrocautery knife and used as the entrance into the thoracic cavity. Using the transumbilical technique, anatomic lobectomy was performed with electrosurgical devices and endoscopic vascular staplers in 15 canines. Transumbilical endoscopic anatomic lobectomy was successfully completed in 12 of the 15 animals. Intraoperative bleeding developed in three animals during pulmonary hilum dissection, where one animal was killed due to hemodynamic instability and the other two animals required thoracotomy to complete the operation. There were five delayed bleeding and surgical mortality cases caused by inadequate vessel sealing by electrosurgical devices. Postmortem examination confirmed correct transumbilical lobectomy in the twelve animals that survived the operations. Transumbilical anatomic lobectomy is technically feasible in a canine model; however, the electrosurgical devices were not effective in sealing the pulmonary vessel in the current canine model.

Intractable hematuria from the bladder or the prostate can be life-threatening and its management remains a difficult clinical problem. Severe bleeding can arise as a result of radiation cystitis, bladder carcinoma, cyclophosphamide-induced cystitis, severe infection, transurethral resection of the prostate and prostate cancer. When irrigation of the bladder through a three-way catheter and fulguration of the bleeding lesions fail to stop the hematuria, a life-threatening situation can develop, when blood transfusion fails to keep pace with the rate of blood loss. Patients with massive uncontrollable hematuria are often elderly and unfit for cystectomy as a treatment. Many urologists have had to manage this difficult problem, and several different treatments have been attempted and described, with varying degrees of success. Transcatheter arterial embolization of the vesical or prostatic arteries is occasionally indicated in these patients when all other measures have failed. There is limited published experience with this procedure, but success in 90% of patients is reported when the vesical or prostatic arteries can be identified. The aim of this review is to describe the current place of transcatheter arterial embolization in the management of severe bladder or prostate bleeding after failed conservative therapy, and to review its efficacy and morbidity.

Reinforced endostapling can prevent postoperative air leakage from surgical stumps. We herein present a 58-year old woman with idiopathic interstitial pneumonia who developed lethal haemothorax after a thoracoscopic lung biopsy with the use of an endostapler preloaded with bioabsorbable tissue reinforcement material. This lethal haemothorax, which occurred on the day after the lung biopsy, required an emergency operation. The bleeding point was an intercostal artery of the inferior chest wall adjacent to the surgical stump. The operative findings suggested that the reinforced material on the surgical stump scratched the chest wall through respiratory movement. PMID:22184467

This report describes the case of a 55-year-old woman with varicella-zoster virus (VZV) sacral meningoradiculitis (Elsberg syndrome) who presented with herpes zoster in the left S2 dermatome area, urinary retention, and constipation. Lumbar magnetic resonance imaging showed the left sacral nerve root swelling with enhancement. Thereafter, she suddenly showed massive hematochezia and hemorrhagic shock because of a rectal ulcer. To elucidate the relation between Elsberg syndrome and rectal ulcer, accumulation of similar cases is necessary. To avoid severe complications, attention must be devoted to the possibility of rectal bleeding in the early stage of Elsberg syndrome.

Purpose: Catheter-directed thrombolysis (CDT) is a highly effective approach in the treatment of deep venous thrombosis (DVT). There are no data on the primary use of CDT with argatroban and tissue plasminogen activator (tPA) in patients without heparin-induced thrombocytopenia (HIT). The aim of this study was to evaluate the efficacy and safety of the combined administration of argatroban and tPA during CDT for massive DVT in patients without HIT. Methods: Thirty-three patients with massive symptomatic iliac and femoropopliteal DVT underwent CDT with tPA and argatroban within 28 {+-} 6 h of presentation. The dose of tPA was 0.75-1 mg/h throughmore » the infusion port and that of argatroban at 0.3-1 {mu}g/kg/min through the side port of the sheath. The patients were evaluated for the efficacy and safety of CDT and recurrent symptomatic venous thromboembolism (VTE) at a mean follow-up of 22 months. Results: There was no bleeding or iatrogenic pulmonary embolism with the CDT regimen we used. Grade III lysis (complete resolution of thrombus on venography) was achieved in 30 patients (91 %). In 3 patients with additional inferior vena cava filter thrombosis, further thrombectomy of the filter was required. No patient developed recurrent VTE. Conclusion: Concomitant administration of argatroban and tPA is a highly safe and effective regimen for CDT for massive DVT.« less

Severe Abnormal Uterine Bleeding (SAUB) is a common gynecological disorder. The clinical characteristics include disordered menstrual cycle and massive bleeding that can cause anemia or secondary infection. Current treatment mainly relies on drug therapy or surgical removal of the uterus, each having its significant disadvantages. How to preserve the uterus, reduce the pain from surgery, and achieve better treatment effects have been well known but remaining as unresolved issues. This study aims at evaluating two types of radiofrequency (RF) thermocoagulation procedures for the treatment of SAUB: the RF-A procedure group included 25 SAUB patients ≥45 years of age treated for amenorrhea; the RF-B procedure group included 51 patients at <45 years of age treated for the control of excessive bleeding. Post-treatment ratings of menstrual satisfaction and pre-/post-treatment menstrual scores-pictorial blood loss assessment chart (PBAC)-and hemoglobin levels were collected; and the mean length of follow-up was 72 months. Also, 38 SAUB patients treated with standard drug regimens served as a control group. The results of the study showed that following RF treatment, the average long-term patient menstrual satisfaction was greater than 92 %. In both the RF groups, PBAC scores and hemoglobin levels were significantly improved from baseline (p < .05). Compared with the control group, PBAC scores and hemoglobin levels were also significantly better for the RF groups at 6-24-month post-operation. Patients experienced no hysterectomy in association with the RF procedures. In conclusion, this pilot study suggests that the novel RF procedures are both safe and effective in treating patients with SAUB. Further investigation is necessary to evaluate their application in broader clinical indication.

Management of bleeding in vascular surgery.

Chee, Y E; Liu, S E; Irwin, M G

Management of acute coagulopathy and blood loss during major vascular procedures poses a significant haemostatic challenge to anaesthetists. The acute coagulopathy is multifactorial in origin with tissue injury and hypotension as the precipitating factors, followed by dilution, hypothermia, acidemia, hyperfibrinolysis and systemic inflammatory response, all acting as a self-perpetuating spiral of events. The problem is confounded by the high prevalence of antithrombotic agent use in these patients and intraoperative heparin administration. Trials specifically examining bleeding management in vascular surgery are lacking, and much of the literature and guidelines are derived from studies on patients with trauma. In general, it is recommended to adopt permissive hypotension with a restrictive fluid strategy, using a combination of crystalloid and colloid solutions up to one litre during the initial resuscitation, after which blood products should be administered. A restrictive transfusion trigger for red cells remains the mainstay of treatment except for the high-risk patients, where the trigger should be individualized. Transfusion of blood components should be initiated by clinical evidence of coagulopathy such as diffuse microvascular bleeding, and then guided by either laboratory or point-of-care coagulation testing. Prophylactic antifibrinolytic use is recommended for all surgery where excessive bleeding is anticipated. Fibrinogen and prothrombin complex concentrates administration are recommended during massive transfusion, whereas rFVIIa should be reserved until all means have failed. While debates over the ideal resuscitative strategy continue, the approach to vascular haemostasis should be scientific, rational, and structured. As far as possible, therapy should be monitored and goal directed. © The Author 2016. Published by Oxford University Press on behalf of the British Journal of Anaesthesia. All rights reserved.

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

2015-10-01

This Guideline is an official statement of the European Society of Gastrointestinal Endoscopy (ESGE). It addresses the diagnosis and management of nonvariceal upper gastrointestinal hemorrhage (NVUGIH). Main Recommendations MR1. ESGE recommends immediate assessment of hemodynamic status in patients who present with acute upper gastrointestinal hemorrhage (UGIH), with prompt intravascular volume replacement initially using crystalloid fluids if hemodynamic instability exists (strong recommendation, moderate quality evidence). MR2. ESGE recommends a restrictive red blood cell transfusion strategy that aims for a target hemoglobin between 7 g/dL and 9 g/dL. A higher target hemoglobin should be considered in patients with significant co-morbidity (e. g., ischemic cardiovascular disease) (strong recommendation, moderate quality evidence). MR3. ESGE recommends the use of the Glasgow-Blatchford Score (GBS) for pre-endoscopy risk stratification. Outpatients determined to be at very low risk, based upon a GBS score of 0 - 1, do not require early endoscopy nor hospital admission. Discharged patients should be informed of the risk of recurrent bleeding and be advised to maintain contact with the discharging hospital (strong recommendation, moderate quality evidence). MR4. ESGE recommends initiating high dose intravenous proton pump inhibitors (PPI), intravenous bolus followed by continuous infusion (80 mg then 8 mg/hour), in patients presenting with acute UGIH awaiting upper endoscopy. However, PPI infusion should not delay the performance of early endoscopy (strong recommendation, high quality evidence). MR5. ESGE does not recommend the routine use of nasogastric or orogastric aspiration/lavage in patients presenting with acute UGIH (strong recommendation, moderate quality evidence). MR6. ESGE recommends intravenous erythromycin (single dose, 250 mg given 30 - 120 minutes prior to upper gastrointestinal [GI] endoscopy) in patients with clinically severe or ongoing active UGIH. In selected patients, pre-endoscopic infusion of erythromycin significantly improves endoscopic visualization, reduces the need for second-look endoscopy, decreases the number of units of blood transfused, and reduces duration of hospital stay (strong recommendation, high quality evidence). MR7. Following hemodynamic resuscitation, ESGE recommends early (≤ 24 hours) upper GI endoscopy. Very early (< 12 hours) upper GI endoscopy may be considered in patients with high risk clinical features, namely: hemodynamic instability (tachycardia, hypotension) that persists despite ongoing attempts at volume resuscitation; in-hospital bloody emesis/nasogastric aspirate; or contraindication to the interruption of anticoagulation (strong recommendation, moderate quality evidence). MR8. ESGE recommends that peptic ulcers with spurting or oozing bleeding (Forrest classification Ia and Ib, respectively) or with a nonbleeding visible vessel (Forrest classification IIa) receive endoscopic hemostasis because these lesions are at high risk for persistent bleeding or rebleeding (strong recommendation, high quality evidence). MR9. ESGE recommends that peptic ulcers with an adherent clot (Forrest classification IIb) be considered for endoscopic clot removal. Once the clot is removed, any identified underlying active bleeding (Forrest classification Ia or Ib) or nonbleeding visible vessel (Forrest classification IIa) should receive endoscopic hemostasis (weak recommendation, moderate quality evidence). MR10. In patients with peptic ulcers having a flat pigmented spot (Forrest classification IIc) or clean base (Forrest classification III), ESGE does not recommend endoscopic hemostasis as these stigmata present a low risk of recurrent bleeding. In selected clinical settings, these patients may be discharged to home on standard PPI therapy, e. g., oral PPI once-daily (strong recommendation, moderate quality evidence). MR11. ESGE recommends that epinephrine injection therapy not be used as endoscopic monotherapy. If used, it should be combined with a second endoscopic hemostasis modality (strong recommendation, high quality evidence). MR12. ESGE recommends PPI therapy for patients who receive endoscopic hemostasis and for patients with adherent clot not receiving endoscopic hemostasis. PPI therapy should be high dose and administered as an intravenous bolus followed by continuous infusion (80 mg then 8 mg/hour) for 72 hours post endoscopy (strong recommendation, high quality evidence). MR13. ESGE does not recommend routine second-look endoscopy as part of the management of nonvariceal upper gastrointestinal hemorrhage (NVUGIH). However, in patients with clinical evidence of rebleeding following successful initial endoscopic hemostasis, ESGE recommends repeat upper endoscopy with hemostasis if indicated. In the case of failure of this second attempt at hemostasis, transcatheter angiographic embolization (TAE) or surgery should be considered (strong recommendation, high quality evidence). MR14. In patients with NVUGIH secondary to peptic ulcer, ESGE recommends investigating for the presence of Helicobacter pylori in the acute setting with initiation of appropriate antibiotic therapy when H. pylori is detected. Re-testing for H. pylori should be performed in those patients with a negative test in the acute setting. Documentation of successful H. pylori eradication is recommended (strong recommendation, high quality evidence). MR15. In patients receiving low dose aspirin for secondary cardiovascular prophylaxis who develop peptic ulcer bleeding, ESGE recommends aspirin be resumed immediately following index endoscopy if the risk of rebleeding is low (e. g., FIIc, FIII). In patients with high risk peptic ulcer (FIa, FIb, FIIa, FIIb), early reintroduction of aspirin by day 3 after index endoscopy is recommended, provided that adequate hemostasis has been established (strong recommendation, moderate quality evidence). © Georg Thieme Verlag KG Stuttgart · New York.

Massive transfusion (MT) is a lifesaving treatment for trauma patients with hemorrhagic shock, assessed by Assessment of Blood Consumption (ABC) Score based on mechanism of injury, systolic blood pressure (SBP), tachycardia, and FAST exam. The aim of this study was to assess the performance of ABC score by replacing hypotension and tachycardia; with Shock Index (SI) > 1.0 and including pelvic fractures. We performed a 2-year (2014-2015) analysis of all high-level trauma activations and excluded patients dead on arrival. The ABC score was calculated using the 4-point score [blunt (0)/penetrating trauma (1), HR ≥ 120 (1), SBP ≤ 90 mmHg (1), and FAST positive (1)]. The Revised Assessment of Bleeding and Transfusion (RABT) score also included 4 points, calculated by replacing HR and SBP with SI > 1.0 and including pelvic fracture. AUROC compared performances of the two scores. A total of 380 patients were included. The overall MT was 27%. Patients receiving MT had higher median ABC scores [1.1 (0-2) vs. 1 (0-2), p = 0.15] and RABT scores [2 (1-3) vs. 1 (0-2), p < 0.001]. The RABT score had better discriminative power (AUROC = 0.828) compared to ABC score (AUROC = 0.617) for predicting the need for MT. Cutoff of RABT score ≥ 2 had a sensitivity of 84% and specificity of 77% for predicting need for MT compared to ABC score with 39% sensitivity and 72% specificity. Replacement of hypotension and tachycardia with a SI > 1.0 and inclusion of pelvic fracture enhanced discrimination of ABC score for predicting the need for MT. The current ABC score would benefit from revision to more appropriately identify patients requiring MT.

We investigated the effect of implementing adaptive plasma ordering criteria in the computerized physician order entry (CPOE) system, with alerts that were automatically generated if the recipient's antecedent international normalized ratio (INR) did not meet the institutional criteria. In a regional health care system consisting of 11 hospitals using a common CPOE, data on the number of plasma orders and alerts that were generated were collected over a 4-month period before prescribers were required to select an indication for plasma. When adaptive ordering was implemented prescribers had to choose from prepopulated indications for plasma: INR of 1.6 or greater with bleeding, INR of 1.6 or greater before an invasive procedure, therapeutic exchange, massive transfusion, and other. Regardless of the antecedent INR the alert did not trigger if massive transfusion or plasmapheresis was selected. Information on prescribers and recipients was collected during this 5-month period. In the 4-month period before the adaptive alerts were implemented, 42.9% of the plasma orders generated an alert; in the 5-month period thereafter the alert rate was significantly lower at 27.9% (p < 0.0001). The percentage of heeded alerts increased during the adaptive alert period (24.3% vs. 17.1%, respectively, p = 0.004). A significant percentage (45%) of other plasma orders were for periprocedure or bleeding patients whose antecedent INR was less than 1.6. There were significant differences in prescriber specialties among those who ordered plasma using the other indication compared to all plasma orders. Electronic interventions improve compliance with plasma guidelines but as implemented are not sufficient to completely curtail non-evidence-based ordering. © 2013 American Association of Blood Banks.

Can very high level of D-dimer exclusively predict the presence of thromboembolic diseases?

PubMed

Ho, Chao-Hung

2011-04-01

D-dimer quantitative test is mainly used to rule out the presence of thromboembolic diseases (TEDs). Whether very high D-dimer (100 times above the cutoff point) can exclusively indicate the presence of TED should be known. D-dimer was detected by a quantitative immunoturbidimetric assay. The normal value is 0.2-0.7 mg/L fibrinogen equivalent units (FEUs). During the year of 2009, 1,053 D-dimer tests were performed. We analyzed the results of these patients to find out the causes of very high D-dimer. The mean value of D-dimer in the 1,053 tests was 8.56 mg/L FEU, ranging from <0.2 mg/L to 563.2 mg/L FEU. Of them, 28 samples from 21 patients had very high D-dimer value: >50 mg/L FEU. Of the 21 patients, 9 (43%) had TED, 1 had suspected TED, but not proved by computed tomographic (CT) angiogram, 3 had massive gastrointestinal or other site bleeding, 3 patients had cardiac arrest with samples taken immediately after recovery from cardiopulmonary resuscitation (CPR), 2 had sepsis with disseminated intravascular coagulation (DIC), 1 had postpartum hemolysis, elevated liver enzymes, low platelets (HELLP) syndrome with acute pulmonary edema and renal failure, 1 had multiple traumatic injury, and 1 received thrombolytic therapy. Although TED was the most frequently seen disorder in patients with very high D-dimer value, very high D-dimer was not necessary exclusively the marker of TED. Other disorders such as massive bleeding, status post CPR, sepsis with DIC, multiple traumatic injuries, hyperfibrinolysis and HELLP syndrome can also have very high D-dimer. Copyright © 2011.

Massive hemoptysis mostly arises from the bronchial arteries; however, bleeding can also occur from a lesion in injured pulmonary arteries, such as pulmonary artery aneurysm/pseudoaneurysm (PAA/PAP), during pulmonary infection. A 66-year-old man was admitted with a diagnosis of lung abscess in the right lower lobe that was complicated with pyothorax. Intravenous administration of antibiotics and thoracic drainage successfully controlled the infection and inflammation until day 16, when the patient began to exhibit hemoptysis and bloody pleural effusion. Enhanced computed tomography (CT) with multi-planer reconstruction (MPR) images showed a highly enhanced mass inside the abscess fed by the pulmonary artery, suggesting PAA/PAP. Pulmonary angiography confirmed PAA/PAP, and embolization with coils successfully stopped both the bleeding into the sputum and pleural effusion, with a collapsed aneurysm visible on chest CT scan. Clinicians should consider the possibility of PAA/PAP in the differential diagnosis of hemoptysis during the treatment of patients with lung abscess. MPR CT is helpful for the diagnosis of PAA/PAP and its feeding vessels.

A four-year-old female was admitted to a university-based children's hospital with a newly-diagnosed posterior fossa tumor. She was started on famotidine and high-dose dexamethasone and underwent gross total resection of a medulloblastoma. She was continued on dexamethasone and famotidine. She exhibited postoperative posterior fossa syndrome and was started on enteral feeds via the nasoduodenal tube. She had small gastrointestinal bleeds on postoperative days eight, 11, and 18, and was found to have a well-circumscribed posterior duodenal ulcer. On postoperative day 19, she suffered a massive life-threatening gastrointestinal bleed requiring aggressive resuscitation with blood products. She required an emergent laparotomy due to ongoing blood loss and she was found to have posterior duodenal wall erosion into her gastroduodenal artery. She recovered and subsequently began delayed chemotherapy. This case demonstrates a rare and life-threatening complication of high-dose dexamethasone therapy in the setting of posterior fossa pathology despite stress ulcer prophylaxis. We present a historical perspective with the review of the association between duodenal and intracranial pathology and the usage of high-dose dexamethasone in such cases.

Pulmonary Embolism in 2017: How We Got Here and Where Are We Going?

PubMed

Merli, Geno J

2017-09-01

In the 1970s, both the Urokinase Pulmonary Embolism and Urokinase-Streptokinase Pulmonary Embolism trials began the quest to develop thrombolytic therapy for the treatment of acute massive and submassive pulmonary embolism (PE). The goals of these studies were the immediate reduction in clot burden, restoration of hemodynamic stability, and improved survival. Major bleeding became the major barrier for clinicians to employ these therapies. From 1980s to the present time, a number of studies using recombinant tissue-type plasminogen activator for achieving these same above outcomes were completed but major bleeding continued to remain an adoption barrier. Finally, the concept of bringing the thrombolytic agent into the clot has entered the quest for the Holy Grail in the treatment of PE. This article will review all the major trials using peripheral thrombolysis and provide insight into the need for a team approach to pulmonary care (Pulmonary Embolism Response Team), standardization of pulmonary classification, and the need for trials designed for both short- and long-term outcomes using thrombolysis for selected PE populations.

Acute lower gastrointestinal bleeding (LGIB) is a common indication for emergency hospitalisation worldwide. In contrast to upper GIB, patient characteristics, modes of investigation, transfusion, treatment and outcomes are poorly described. There are minimal clinical guidelines to inform care pathways and the use of endoscopy, including (diagnostic and therapeutic yields), interventional radiology and surgery are poorly defined. As a result, there is potential for wide variation in practice and clinical outcomes. The UK Lower Gastrointestinal Bleeding Audit is a large nationwide audit of adult patients acutely admitted with LGIB or those who develop LGIB while hospitalised for another reason. Consecutive, unselected presentations with LGIB will be enrolled prospectively over a 2-month period at the end of 2015 and detailed data will be collected on patient characteristics, comorbidities, use of anticoagulants, transfusion, timing and modalities of diagnostic and therapeutic procedures, clinical outcome, length of stay and mortality. These will be audited against predefined minimum standards of care for LGIB. It is anticipated that over 80% of all acute hospitals in England and some hospitals in Scotland, Wales and Northern Ireland will participate. Data will be collected on the availability and organisation of care, provision of diagnostic and therapeutic GI endoscopy, interventional radiology, surgery and transfusion protocols. This audit will be conducted as part of the national comparative audit programme of blood transfusion through collaboration with specialists in gastroenterology, surgery and interventional radiology. Individual reports will be provided to each participant site as well as an overall report and disseminated through specialist societies. Results will also be published in peer-reviewed journals. The study has been funded by National Health Services (NHS) Blood and Transplant and the Bowel Disease Research Foundation and endorsed by the Association of Coloproctology of Great Britain and Ireland.

To reduce unnecessary lab testing by predicting when a proposed future lab test is likely to contribute information gain and thereby influence clinical management in patients with gastrointestinal bleeding. Recent studies have demonstrated that frequent laboratory testing does not necessarily relate to better outcomes. Data preprocessing, feature selection, and classification were performed and an artificial intelligence tool, fuzzy modeling, was used to identify lab tests that do not contribute an information gain. There were 11 input variables in total. Ten of these were derived from bedside monitor trends heart rate, oxygen saturation, respiratory rate, temperature, blood pressure, and urine collections, as well as infusion products and transfusions. The final input variable was a previous value from one of the eight lab tests being predicted: calcium, PTT, hematocrit, fibrinogen, lactate, platelets, INR and hemoglobin. The outcome for each test was a binary framework defining whether a test result contributed information gain or not. Predictive modeling was applied to recognize unnecessary lab tests in a real world ICU database extract comprising 746 patients with gastrointestinal bleeding. Classification accuracy of necessary and unnecessary lab tests of greater than 80% was achieved for all eight lab tests. Sensitivity and specificity were satisfactory for all the outcomes. An average reduction of 50% of the lab tests was obtained. This is an improvement from previously reported similar studies with average performance 37% by [1-3]. Reducing frequent lab testing and the potential clinical and financial implications are an important issue in intensive care. In this work we present an artificial intelligence method to predict the benefit of proposed future laboratory tests. Using ICU data from 746 patients with gastrointestinal bleeding, and eleven measurements, we demonstrate high accuracy in predicting the likely information to be gained from proposed future lab testing for eight common GI related lab tests. Future work will explore applications of this approach to a range of underlying medical conditions and laboratory tests. Copyright © 2012 Elsevier Ireland Ltd. All rights reserved.

Making extreme computations possible with virtual machines

State-of-the-art algorithms generate scattering amplitudes for high-energy physics at leading order for high-multiplicity processes as compiled code (in Fortran, C or C++). For complicated processes the size of these libraries can become tremendous (many GiB). We show that amplitudes can be translated to byte-code instructions, which even reduce the size by one order of magnitude. The byte-code is interpreted by a Virtual Machine with runtimes comparable to compiled code and a better scaling with additional legs. We study the properties of this algorithm, as an extension of the Optimizing Matrix Element Generator (O'Mega). The bytecode matrix elements are available as alternative input for the event generator WHIZARD. The bytecode interpreter can be implemented very compactly, which will help with a future implementation on massively parallel GPUs.

Giant planet migration during FU Orionis outbursts: 1D disc models

NASA Astrophysics Data System (ADS)

Dunhill, A. C.

2018-05-01

I present the results of semi-analytic calculations of migrating planets in young, outbursting circumstellar discs. Formed far out in the disc via gravitational fragmentation early on in its lifetime, these planets typically migrate at very slow rates and are therefore mostly expected to remain at large radii (such as is the case in HR 8799). I show that changes in the disc structure during FUor outbursts affect the planet's ability to maintain a gap and can allow a massive giant planet's semimajor axis to reduce by almost 5 per cent in a single outburst under the most optimistic conditions. Given that a single disc will likely undergo ˜10 such outbursts this process can significantly alter the expected radial distribution for GI-formed planets.

The aim of this pilot study was to investigate the effects of four weeks of an oral health optimized diet on periodontal clinical parameters in a randomized controlled trial. The experimental group (n = 10) had to change to a diet low in carbohydrates, rich in Omega-3 fatty acids, and rich in vitamins C and D, antioxidants and fiber for four weeks. Participants of the control group (n = 5) did not change their dietary behavior. Plaque index, gingival bleeding, probing depths, and bleeding upon probing were assessed by a dentist with a pressure-sensitive periodontal probe. Measurements were performed after one and two weeks without a dietary change (baseline), followed by a two week transitional period, and finally performed weekly for four weeks. Despite constant plaque values in both groups, all inflammatory parameters decreased in the experimental group to approximately half that of the baseline values (GI: 1.10 ± 0.51 to 0.54 ± 0.30; BOP: 53.57 to 24.17 %; PISA: 638 mm(2) to 284 mm(2)). This reduction was significantly different compared to that of the control group. A diet low in carbohydrates, rich in Omega-3 fatty acids, rich in vitamins C and D, and rich in fibers can significantly reduce gingival and periodontal inflammation.

cetuximab, an epidermal growth factor receptor inhibitor, is a targeted therapeutic regimen of colorectal cancers. Several common adverse effects have been found, such as cutaneous or gastrointestinal toxicity. However, according to the articles had been published, upper gastrointestinal bleeding (UGIB) is considered to be rare and its mechanism remains unclear. In this report, we presented a 42-year-old male patient with advanced recto-sigmoid cancer. After palliative operation, the patient suffered from complete upper gastrointestinal (GI) obstruction, which was induced by extensive abdominal metastasis of the tumor. Considering his poor condition, we chose the targeted drug, cetuximab, as his further treatment. But after the application of cetuximab, the UGIB immediately happened twice in this patient. UGIB, as a rare complication of cetuximab, occured to the patient. We stopped the bleeding with thrombin, hemocoagulase and somatostatin and suspended the subsequent treatment plan of cetuximab. At the same time, anti-shock treatment was given immediately. He was died of respiratory and circulatory failure caused by UGIB and advanced tumor eventually. UGIB should be considered as a rare but severe complication of cetuximab. When cetuximab is applied for patients with advanced colon tumors, more cautions should be required if the patients are accompanied by upper gastrointestinal obstruction. In addition, for those patients who suffered from UGIB recently, cetuximab should be prohibited if the Rockall score ranged > 5 points. Copyright © 2017 The Authors.

Many studies have reported the increased presence of gastrointestinal (GI) symptoms in children with autism spectrum disorders (ASD). Altered microbiome profiles, pro-inflammatory responses and impaired intestinal permeability have been observed in children with ASD and co-morbid GI symptoms, yet few studies have compared these findings to ASD children without GI issues or similarly aged typical developing children. The aim of this study was to determine whether there are biological signatures in terms of immune dysfunction and microbiota composition in children with ASD with GI symptoms. Children were enrolled in one of four groups: ASD and GI symptoms of irregular bowel habits (ASD GI ), children with ASD but without current or previous GI symptoms (ASD NoGI ), typically developing children with GI symptoms (TD GI ) and typically developing children without current or previous GI symptoms (TD NoGI ). Peripheral blood mononuclear cells (PBMC) were isolated from the blood, stimulated and assessed for cytokine production, while stool samples were analyzed for microbial composition. Following Toll-Like receptor (TLR)-4 stimulation, the ASD GI group produced increased levels of mucosa-relevant cytokines including IL-5, IL-15 and IL-17 compared to ASD NoGI . The production of the regulatory cytokine TGFβ1 was decreased in the ASD GI group compared with both the ASD NoGI and TD NoGI groups. Analysis of the microbiome at the family level revealed differences in microbiome composition between ASD and TD children with GI symptoms; furthermore, a predictive metagenome functional content analysis revealed that pathways were differentially represented between ASD and TD subjects, independently of the presence of GI symptoms. The ASD GI also showed an over-representation of the gene encoding zonulin, a molecule regulating gut permeability, compared to the other groups. Overall our findings suggest that children with ASD who experience GI symptoms have an imbalance in their immune response, possibly influenced by or influencing metagenomic changes, and may have a propensity to impaired gut barrier function which may contribute to their symptoms and clinical outcome.

The aim of this randomised, parallel, double-blind study, in which 28 adult patients diagnosed with chronic gingivitis or early stages of chronic periodontitis were recruited, was to evaluate the efficacy of 'Gamadent' toothpaste compared to a placebo toothpaste. 'Gamadent' toothpaste has all the basic constituents of a toothpaste with the addition of a sea cucumber extract (SCE) of the species Stichopus sp. 1 to improve the healing potential of tissues. The placebo has the same basic constituents minus the extract. Out of the 28 patients, 14 were placed in the test group who used the 'Gamadent' toothpaste, and 14 patients were placed in the control group (2 control subjects defaulted and were excluded), who brushed using the placebo toothpaste. The longitudinal study was carried out over a period of 3 months with assessments made at baseline, 1 month, 2 months and 3 months after conventional therapy at the baseline visit. The clinical parameters used during the trial were Plaque Index (PI), Gingival Index (GI), Papilla Bleeding Index (PBI) and Probing Pocket Depth (PPD). A predetermined number of sites on a molar, premolar, canine and an incisor were examined and evaluated in each quadrant. After the baseline assessment, the patients had full mouth scaling and debridement as well as oral hygiene instructions. Patients were instructed to brush their teeth twice a day with the toothbrush provided (Oral-B plus, size 35) and toothpaste (test or control), using the Bass technique. At the 1-month assessment, there were significant mean reductions to baseline mean values in PI (P < 0.005) and GI (P < 0.001) in the test group as compared to the control group. At the end of the 2-month interval, significant reductions were observed in PI, PBI and PPD (P < 0.001). By the end of 3 months, there were significant differences in the mean reduction of all the parameters i.e. PI, PBI, GI and PPD (P < 0.001), between the test and control sites. In conclusion, 'Gamadent' toothpaste provided noteworthy benefits, producing statistically significant improvement in all clinical parameters compared to the placebo during the healing phase after conventional initial therapy.

Pregnancy gingivitis and causal inference.

Niederman, Richard

2013-12-01

The PubMed and Embase databases were searched together with hand searching of the Journal of Periodontology, Journal of Periodontal Research and Journal of Clinical Periodontology. The reference lists of identified articles were also searched. Prospective cohort or cross-sectional studies assessing the effect of pregnancy on gingival inflammation evaluated by the gingival index and/or bleeding on probing were included. Study quality was assessed using the Newcastle-Ottawa scale (NOS). Study assessment and data extraction were carried out independently by two reviewers, with disputes resolved by a third reviewer. Mean values of primary and secondary outcomes were directly pooled and analysed with weighted mean differences (WMDs) and 95% confidence intervals (CIs), considering independently each study design (cohort and cross-sectional). Study specific estimates were pooled with both the fixed- and random-effect models. Forty-four articles representing 33 studies (14 cohort and 19 cross-sectional) were included. Meta-analyses revealed a significantly lower GI in pregnant women in the first term compared with those in their second or third term of pregnancy; a lower mean GI score in post-partum women compared with women in their second [WMD = 0.143; 95% CI (0.031; 0.255); p = 0.012] or third term [WMD = 0.256; 95% CI (0.151; 0.360); p < 0.001] of pregnancy, when considering cohort studies; non-pregnant women had lower mean GI values than women in their second or third term of pregnancy. Small changes in plaque levels were reported. The results of this systematic review confirm that gingival inflammation is significantly increased throughout pregnancy and when comparing pregnant versus post-partum or non-pregnant women, without a concomitant increase in plaque levels. However, this information should be considered with caution, due to the small number of studies included in the meta-analyses, the low quality of the included studies, differences in study design, absence of a periodontal diagnosis at baseline and performance of periodontal treatment in some cases. No conclusions could be drawn regarding secondary outcomes such as microbiological, immunological and patient-centred data, because no meta-analyses were possible for these factors. Future studies with higher quality should be designed to answer these questions.

Perceived Barriers to Application of Glycaemic Index: Valid Concerns or Lost in Translation?

PubMed Central

Grant, Shannan M.; Wolever, Thomas M. S.

2011-01-01

The term glycaemic-index (GI) originally appeared in the literature in the early 1980s. GI categorizes carbohydrate according to glycaemic effect postprandially. Since its inception, GI has obtained and maintained interest of academics and clinicians globally. Upon review of GI literature, it becomes clear that the clinical utility of GI is a source of controversy. Can and should GI be applied clinically? There are academics and clinicians on both sides of the argument. Certainly, this controversy has been a stimulus for the evolution of GI methodology and application research, but may also negatively impact clinicians’ perception of GI if misunderstood. This article reviews two assessments of GI that are often listed as barriers to application; the GI concept is (1) too complex and (2) too difficult for clients to apply. The literature reviewed does not support the majority of purported barriers, but does indicate that there is a call from clinicians for more and improved GI education tools and clinician GI education. The literature indicates that the Registered Dietitian (RD) can play a key role in GI knowledge translation; from research to application. Research is warranted to assess GI education tool and knowledge needs of clinicians and the clients they serve. PMID:22254100

The effects of bodybuilding and protein supplements on periodontal tissues have not yet been evaluated. The present study aimed to examine the periodontal status and interleukin (IL)-1β, apoptosis-associated speck-like protein containing C-terminal caspase-recruitment domain (ASC), and caspase 1 (CASP1) gene expression levels of body builders compared with those of controls. Twenty-five bodybuilders with gingivitis (BB-G) who used protein powder supplements were compared with 25 nonexercising males with (G) and 25 without (H) gingivitis. Saliva, gingival crevicular fluid (GCF), and serum were collected for gene expression analysis. Plaque index (PI), gingival index (GI), probing depth (PD), clinical attachment level (CAL), and bleeding on probing (BOP) were recorded. GI and BOP were higher in group BB-G and G than in group H (P < 0.01), but PI, PD, and CAL were similar between groups (P > 0.05). In GCF, CASP1, ASC, and IL-1β expression were upregulated in group G compared with groups BB-G and H (P < 0.01). In addition, ASC (P < 0.05) and IL-1β (P < 0.01) were downregulated in group BB-G compared with group H. CASP1, IL-1β (P < 0.01), and ASC in the saliva were downregulated in group BB-G compared with groups H and G (P < 0.05). CASP1, IL-1β, and ASC may play a role in the pathogenesis of gingivitis. Bodybuilding and supplement usage may decrease gingival inflammation by downregulating CASP1, IL-1β, and ASC.

Investigate short-term effects of power brushing following experimental induction of biofilm overgrowth in periodontal disease states. Overall, 175 subjects representing each of five biofilm-gingival interface (BGI) periodontal groups were enrolled in a single-blind, randomized study. After stent-induced biofilm overgrowth for 21 days subjects received either a manual or a power toothbrush to use during a 4 weeks resolution phase. At baseline and during induction and resolution, standard clinical parameters were measured. Subclinical parameters included multikine analysis of 13 salivary biomarkers and 16s Human Oral Microbe Identification Microarray (HOMIM) probe analysis of subgingival plaque samples. All groups exhibited significantly greater reductions in bleeding on probing (BOP) (p = 0.002), gingival index (GI) (p = 0.0007), pocket depth (PD) (p = 0.04) and plaque index (p = 0.001) with power brushing compared to manual. When BGI groups were combined to form a shallow PD (PD ≤ 3 mm) and a deep PD group (PD > 4 mm) power brushing reduced BOP and GI in subjects with both pocket depths. Power brushing significantly reduced IL-1β levels at resolution while changes in bacterial levels showed non-significant trends between both brushing modalities. Short-term changes in select clinical parameters and subclinical salivary biomarkers may be useful in assessing efficacy of power brushing interventions in a spectrum of periodontal disease states. © 2013 John Wiley & Sons A/S.

The aim of the study was to determine whether PillCam esophageal capsule endoscopy could replace endoscopy for screening purposes. Material and methods Sixty-two patients with cirrhosis with no previous variceal bleeding had PillCam capsule endoscopy and video endoscopy performed on the same day. Sensitivity, specificity, and positive and negative predictive values (PPV, NPV) of capsule endoscopy were compared to endoscopy for the presence and severity of esophageal and gastric varices, PHG and the need for primary prophylaxis. Patients’ preference was assessed by a questionnaire. Results Four (6%) patients were unable to swallow the capsule. Sensitivity, specificity, PPV and NPV of capsule endoscopy for detecting any esophageal varices (92%, 50%, 92%, 50%), large varices (55%, 91%, 75%, 80%), variceal red signs (58%, 87%, 69%, 80%), PHG (95%, 50%, 95%, 50%), and the need for primary prophylaxis (91%, 57%, 78%, 80%) were not optimal, with only moderate agreement (κ) between capsule and upper GI endoscopy. Had only a capsule endoscopy been performed, 12 (21.4%) patients would have received inappropriate treatment. Capsule endoscopy also failed to detect (0/13) gastric varices. The majority of patients ranked capsule endoscopy as more convenient (69%) and their preferred (61%) method. Conclusions Despite the preference expressed by patients for capsule endoscopy, we believe that upper GI endoscopy should remain the preferred screening method for primary prophylaxis. PMID:27186182

Medline, PubMed, the Cochrane Central Register of Controlled Trials (CENTRAL) and Embase databases. Randomised controlled trials (RCTs) using thermal diode lasers as an adjunct to non-surgical conventional periodontal initial therapy conducted in patients ≥18 years old written in English or Dutch were considered. Study assessment data extraction and quality assessment was carried out independently by two reviewers. The main outcome variables were probing pocket depth (PPD) and clinical attachment loss (CAL), but plaque scores (PS), bleeding scores (BS) and the Gingival Index (GI) were also considered. Meta-analysis was carried out using a random effects model. Nine studies involving 247 patients were included. Seven studies were of split mouth design and two were parallel group studies. The study designs showed considerable heterogeneity and follow up ranged from six weeks to six months. Meta-analysis found no significant effect on PPD, CAL and PS. There was however a significant effect for GI and BS favouring adjunctive use of the diode laser. The collective evidence regarding adjunctive use of the diode laser with SRP indicates that the combined treatment provides an effect comparable to that of SRP alone. With respect to BS the results showed a small but significant effect favouring the diode laser, however, the clinical relevance of this difference remains uncertainStandard . This systematic review questions the adjunctive use of diode laser with traditional mechanical modalities of periodontal therapy in patients with periodontitis. The strength of the recommendation for the adjunctive use of the diode laser is considered to be 'moderate' for changes in PPD and CAL.

Objective: The aim was to compare the efficacy of plaque control and potential effects on gingival recession of the toothbrushes with angled and straight bristles. Materials and Methods: A total of 40 healthy dental students (25 females and 15 males; age range: 23-25 years) participated and two study groups were constituted. Participants were randomly distributed into two groups to use either angled or standard design manual tooth brushes with soft bristles. Oral hygiene indicators and soft tissue levels were monitored for 6 months. Plaque index, gingival index (GI), probing depth, clinical attachment level, and bleeding on probing were measured at six sites. Vertical recession (VR) and horizontal recession (HR) were also recorded. All measurements were repeated at 3 and 6 months. Results: Plaque scores were reduced significantly at 6 months compared to baseline in both groups (P < 0.05 and P < 0.005 in criss-cross and standard design brushes, respectively). Mean GI scores of the criss-cross design were reduced significantly at 6 months (P < 0.05). Inter-group comparisons revealed that gingival recession (GR) values were not statistically significant (P > 0.05) at baseline, 3 and 6 months suggesting no pronounced impact of bristle design in terms of GR (VR = 0.596, HR = 0.572; VR = 0.884, HR = 0.572; VR = 0.884, HR = 0.572 in the groups). Conclusions: Bristle design has little impact on plaque removal capacity of a toothbrush. Both designs are safe enough to prevent GR as long as soft bristle material is used. PMID:25202222

Medline search using key words halitosis, tongue coating, polymerase chain reaction, microbial profile did not reveal any study. Hence, the purpose of the present investigation was to assess the malodor using the organoleptic method and tanita device; to quantify odoriferous microorganisms using Polymerase Chain Reaction technique in chronic periodontitis patients. The study included 30 chronic periodontitis patients. Halitosis was detected using organoleptic assessment & tanita breath alert. Microbial analysis of Pg, Tf & Fn was done using PCR. Plaque index (PI), gingival index (GI), gingival bleeding index (GBI) were recorded. The maximum score of 3 for tongue coating was found in 60% of selected subjects. The tanita breath alert measured VSC level of score 2 in 60% of selected subjects while organoleptic score of 4 was found in 50% of subjects. The maximum mean value of 31.1±36.5 was found to be of F. nucleatum (Fn) followed by P. gingivalis (Pg) (13±13.3) & T. forsythia (Tf) (7.16±8.68) in tongue samples of selected patients. A weak positive correlation was found between VSC levels (tanita score & organoleptic score) and clinical parameters. The halitosis assessment by measuring VSC levels using organoleptic method and tanita breath alert are clinically feasible. Maximum tongue coating was found in 60% of patients. Fn was found comparatively more than the Pg & Tf. A weak positive correlation was found between VSC levels and clinical parameters such as PI, GI & GBI. Thus,the dentist/ periodontist should emphasise on tongue cleaning measures that would reduce the odoriferous microbial load.

Host modulation is fast gaining popularity as a preferred therapeutic modality for periodontal disease. Recent research in the medical field into herbal immunomodulators such as Septilin® has spurred an interest in evaluating its efficacy in periodontitis for the first time. The aim of the study was to assess the immunomodulatory effects of the herbal immunomodulator Septilin® (Himalaya Drug Company, Bangalore, India) when used as an adjunct to scaling and root planing in chronic periodontal disease. Forty systemically healthy patients aged between 25 and 55 years of age and with chronic periodontitis were randomly divided into two groups. The test group was administered Septilin® tablets for two weeks following scaling and root planing whereas the control group was treated by scaling and root planing alone. Changes in gingival index (GI), gingival bleeding index (GBI), serum C-reactive protein (CRP) levels and salivary tumour necrosis factor-alpha (TNF-α) levels were assessed at day 0, at two weeks, and at three and six months. The GI and GBI showed a statistically significant reduction at two weeks, three months and six months (P<0.001) in both groups. Salivary TNF-α level reduction was significant in the test group only (P<0.001). No significant change was found in serum CRP levels in both groups (P>0.05). In this pilot evaluation, Septilin® was found to be a safe and effective immunomodulator as an adjunct to routine periodontal therapy. Further long-term studies to test Septilin® on larger sections of the population are recommended.

The glycaemic index: importance of dietary fibre and other food properties.

An increasing body of evidence suggests that a low-glycaemic-index (GI) diet has a therapeutic as well as a preventive potential in relation to the insulin resistance syndrome. The implementation of a low-GI diet, however, will require an extended list of low-GI foods to be available on the market. The tailoring of low-GI bread products offers a particular challenge due to their generally high GI and abundance in the diet. Low-GI bread products can be tailored by, for example,enclosure of cereal kernels, sour dough fermentation and/or addition of organic acids, or use of cereal genotypes with elevated contents of amylose or f-glucans. Low-GI cereal foods appear to vary in effect on 'second-meal' glucose tolerance in healthy subjects. In addition to the slow-release properties of such foods, the content of dietary fibre appears to play a role. The low glycaemia to starch in a pasta breakfast (GI 54) promoted a higher glucose tolerance and lowered triacylglycerol levels at a standardized lunch ingested 4 h later, compared with a white-wheat-bread breakfast (GI 100). The metabolic benefits of the low GI properties per se have been demonstrated also in the longer term. Thus, a reduction in dietary GI improved glucose and lipid metabolism and normalized fibrinolytic activity in type 2 diabetics, while maintaining a similar amount and composition of dietary fibre. However, the higher dietary fibre content frequently associated with low-GI foods may add to the metabolic merits of a low-GI diet. Consequently, a low-GI barley meal rich in dietary fibre (GI 53) improved glucose tolerance from evening meal to breakfast, whereas an evening meal with pasta had no effect (GI 54). The exchange of common high-GI bread for low-GI high-fibre bread, as the only dietary modification, improved insulin economy in women at risk of type 2 diabetes. These results are in accordance with epidemiological evidence of a reduced risk of type 2 diabetes with a low-GI diet rich in cereal fibre. It is concluded that low-GI cereal foods developed should preferably be rich in dietary fibre.

Gastrointestinal (GI) events are common adverse events (AEs) associated with delayed-release dimethyl fumarate (DMF), an approved treatment for relapsing-remitting multiple sclerosis (RRMS). The objective of the TOLERATE study was to evaluate GI tolerability and GI mitigation via symptomatic therapies in patients initiating DMF in a real-world clinical setting in Germany. TOLERATE was a multicentre, open-label, single-arm study performed at 25 German sites. Endpoints were frequency, severity, duration (all primary) and mitigation of GI-related events (secondary). Patients were instructed to take DMF according to the prescribing information for up to 12 weeks and to document GI events and intake of GI-symptomatic therapy on numerical rating scales, using eDiaries. A total of 211 patients were included in the safety population (71% female; mean age 40 ± 11 years). Of these, 185 patients (87.7%) reported GI-related events, out of which nearly half received GI-symptomatic therapy (84/185; 45.4%). The most frequently reported GI events were upper abdominal pain, flatulence and nausea. GI-related events peaked during the first 3 weeks of therapy and rapidly decreased thereafter. The severity of GI events over 12 weeks according to the Modified Overall Gastrointestinal Symptom Scale were mild to moderate in the majority of patients reporting GI-related events and taking symptomatic GI medication (53.6%). Only 10% of all patients discontinued study treatment due to AEs in general, while 6.6% discontinued due to GI-related events. The severity of GI-related events decreased over time in patients who received symptomatic treatment with one or more medications (e.g. acid secretion blockers, antidiarrhoeals or antiemetics). Gastrointestinal events associated with delayed-release DMF were mainly mild to moderate in severity. Prevalence of GI events peaked during the first 3 weeks of therapy and rapidly faded thereafter. Although 44.9% of patients experiencing GI events used common GI symptomatic therapies, only 6.6% of patients discontinued DMF because of GI events, suggesting that GI events could be managed well with common symptomatic therapy.

Acute Necrotizing Esophagitis Followed by Duodenal Necrosis

Acute Necrotizing Esophagitis is an uncommon pathology, characterized by endoscopic finding of diffuse black coloration in esophageal mucosa and histological presence of necrosis in patients with upper gastrointestinal bleeding. The first case of acute necrotizing esophagitis followed by duodenal necrosis, in 81 years old woman with a positive history of Type 2 Diabetes Mellitus, Hypertension, and usual intake of Nonsteroidal Anti-inflammatory drugs, is reported. Although its etiology remains unknown, the duodenal necrosis suggests that ischemia could be the main cause given that the branches off the celiac axis provide common blood supply to the distal esophageal and duodenal tissue. The massive gastroesophagic reflux and NSAID intake could be involved. PMID:27957030

In recent years, the search for a less invasive and thus, less painful approach has driven technical innovation in modern thoracic surgery. In this context, subxiphoid uniportal approach has emerged as an alternative to avoid intercostal space manipulation and decrease postoperative pain and intercostal nerve chronic impairment. Subxiphoid uniportal major lung resections have been safe and effective procedures when performed by experienced surgeons even in complex cases or unexpected intraoperative situations. We present six of these surgical scenarios such as big tumors, incomplete or absent fissures, hilar calcified lymph nodes, active bleeding and massive adhesions to show the feasibility of subxiphoid approach to manage even these conditions.

This study was performed to evaluate the relationship between family history of gastrointestinal (GI) cancers and incidence of any GI cancer in the Korean population. Between January 2015 and July 2016, 711 GI cancer patients and 849 controls in 16 hospitals in Korea were enrolled. Personal medical histories, life styles, and family history of GI cancers were collected via questionnaire. There was a significant difference in the incidence of family history of GI cancer between GI cancer patients and controls (p=0.002). Patients with family history of GI cancer tended to be diagnosed as GI cancer at younger age than those without family history (p=0.016). The family members of GI cancer patients who were diagnosed before 50 years of age were more frequently diagnosed as GI cancer before the age of 50 years (p=0.017). After adjusting for major confounding factors, age (adjusted odds ratio [AOR] 1.065, 95% confidence interval [CI]; 1.053-1.076), male gender (AOR 2.270, 95% CI; 1.618-3.184), smoking (AOR 1.570, 95% CI; 1.130-2.182), and sibling's history of GI cancer (AOR 1.973, 95% CI; 1.246-3.126) remained independently associated with GI cancers. GI cancer patients tended to have a first relative with a history of concordant GI cancer. Personal factors (old age and male) and lifestyle (smoking) contribute to the development of GI cancer, independently. Individuals with high risk for GI cancers may be advised to undergo screening at an earlier age.

Pulsating Tonsil Due to Medial Displacement of the Internal Carotid Artery.

BACKGROUND The internal carotid artery (ICA) is about 2.5 cm away from the tonsils. It has no branches in the cervical portion. ICA anomalies of the neck zone may result in a massive arterial bleeding during pharynx and neck surgery. Due to these anomalies, the surgeon must be aware of this risk during tonsillectomy, adenoidectomy, and pharyngeal operations.  CASE REPORT A 23-year-old woman who was discovered to have an acute S curling-type anomaly of the ICA in contact with the lateral border of the right tonsil during a work-up for a tonsillectomy. This anomaly was incidentally discovered via computed tomography (CT) with contrast. In re-evaluating the course of treatment, we found a severe S-shape kink on the right side, bringing it close to the right tonsil by approximately 2 mm, and putting it at severe risk of injury during a simple tonsillectomy, possibly exposing the patient to serious bleeding. Partial tonsillectomy was performed for this patient with the aim to preserve and not expose the internal carotid artery. Pulsation of right tonsil was recorded. The patient made an uneventful postoperative recovery. CONCLUSIONS Undetected ICA anomaly variation can lead to fatal bleeding during a simple procedure, like tonsillectomy. We recommend vigilance during tonsillectomy if one is using a hot dissection method versus a cold dissection method, which may allow for detection of a perioperative ICA anomaly. Tonsillectomy performed by a junior resident should be under direct supervision, particularly if the hot dissection method is used.

Onyx was developed for embolization of central nervous system AVMs but is increasingly used extracranially because of its unique physical properties. We review our experience and results with the use of Onyx for the treatment of fast-flow extracranial vascular lesions. We retrospectively analyzed clinical and imaging records of 22 patients who underwent 71 extracranial embolizations from March 2007 through January 2010. The diagnoses were the following: cervicofacial AVM (n = 18), traumatic fistula (n = 3), and vessel laceration (n = 1). In 62 of 71 procedures (87%), Onyx was the sole embolic agent; it was delivered transarterially in 67/71 and percutaneously in 4/71 procedures. Clinical goals included amelioration of pain and control of bleeding. The clinical efficacy of embolization was judged by symptom control, and adverse events were assessed by clinical examination and history, both postembolization and 4 weeks postprocedure. Cessation of acute bleeding was achieved in 13/14 cases, with 1 case of immediate recurrent massive epistaxis prompting reintubation and further embolization. Control of subacute bleeding episodes and pain was achieved for all patients. Following staged embolization, 7 patients underwent surgical resection without significant blood loss. Surgeons reported high satisfaction with the intraoperative handling properties of Onyx. Transient swelling, local tenderness, or numbness was encountered after 7 procedures. There were no stuck catheters, vessel dissections, or vessel ruptures and no skin discoloration. Staged Onyx embolization was clinically efficacious in managing extracranial fast-flow vascular malformations and lesions, with low associated morbidity.

Gravitational Instabilities in a Young Protoplanetary Disk with Embedded Objects

NASA Astrophysics Data System (ADS)

Desai, Karna M.

Gravitational Instabilities (GIs), a mechanism for angular momentum transport, are prominent during the early phases of protoplanetary disk evolution when the disk is relatively massive. In this dissertation, I analyze GIs by inserting different objects in a disk by employing 3D hydrodynamics simulations. GIs in a circumbinary disks are studied to determine how the presence of the companion affects the nature and strength of GIs in the disk. The circumbinary disk achieves a state of sustained marginal instability similar to an identical disk without the companion. A realistic evolution of the binary is detected. Planet and disk interactions play an important role in the evolution of planetary systems. To study this interaction during the early phases of planet formation, a migration study of Jovian planets in a GI-active disk is conducted. I find the migration timescales to be longer in a GI-active disk, when compared to laminar disks. The 3 MJupiter planet controls its own orbital evolution, while the migration of a 0.3 MJupiter planet is stochastic in nature. I define a 'critical mass' as the mass of an arm of the dominant two-armed spiral density wave within the planet's Hill diameter. Planets above this mass control their own destiny, and planets below this mass are scattered by the disk. This critical mass could provide a recipe for predicting the migration behavior of planets in GI-active disks. To understand the stochastic migration of low-mass planets, I perform a simulation of 240 zero-mass planet-tracers by inserting these at a range of locations in the disk. A Diffusion Coefficient is calculated to characterize the stochastic migration of low-mass objects. The eccentricity dispersion for the sample is also studied. I find that the diffusion of planets can be a slow process, resulting in the survival of small planetary cores.

A 43-year-old female was referred to our hospital for sudden onset of abdominal pain, fullness, and vomiting. Physical examination revealed abdominal distension with mild epigastric tenderness. Abdominal radiography showed massive gastric distension and plain computed tomography (CT) a markedly enlarged stomach filled with gas and fluid. A large volume of gastric contents was suctioned out via a nasogastric (NG) tube. Contrast-enhanced CT showed a grossly distended stomach with displacement of the antrum above the gastroesophageal junction, and the spleen was dislocated inferiorly. Upper gastrointestinal (GI) series showed the greater curvature to be elevated and the gastric fundus to be lower than normal. Acute mesenteroaxial gastric volvulus was diagnosed. GI endoscopy showed a distortion of the gastric anatomy with difficulty intubating the pylorus. Various endoscopic maneuvers were required to reposition the stomach, and the symptoms showed immediate and complete solution. GI fluoroscopy was performed 3 days later. Initially, most of the contrast medium accumulated in the fundus, which was drawn prominently downward, and then began flowing into the duodenum with anteflexion. Elective laparoscopic surgery was performed 1 month later. The stomach was in its normal position, but the fundus was folded posteroinferiorly. The spleen attached to the fundus was normal in size but extremely mobile. We diagnosed a wandering spleen based on the operative findings. Gastropexy was performed for the treatment of gastric volvulus and wandering spleen. The patient remained asymptomatic, and there was no evidence of recurrence during a follow-up period of 24 months. This report describes a rare adult case of acute gastric volvulus associated with wandering spleen. Because delay in treatment can result in lethal complications, it is critical to provide a prompt and correct diagnosis and surgical intervention. We advocate laparoscopic surgery after endoscopic reduction because it is a safe and effective procedure with lower invasiveness.
