    Despite advances in treatment, acute variceal haemorrhage remains life-threatening. To describe contemporary characteristics, management and outcomes of patients with cirrhosis and acute variceal haemorrhage and risk factors for rebleeding and mortality. Multi-centre clinical audit conducted in 212 UK hospitals. In 526 cases of acute variceal haemorrhage, 66% underwent endoscopy within 24h with 64% (n=339) receiving endoscopic therapy. Prior to endoscopy, 57% (n=299) received proton pump inhibitors, 44% (n=232) vasopressors and 27% (n=144) antibiotics. 73% (n=386) received red cell transfusion, 35% (n=184) fresh frozen plasma and 14% (n=76) platelets, with widely varying transfusion thresholds. 26% (n=135) experienced further bleeding and 15% (n=80) died by day 30. The Model for End Stage Liver Disease score was the best predictor of mortality (area under the receiver operating curve=0.74, P<0.001). Neither the clinical nor full Rockall scores were useful predictors of outcome. Coagulopathy was strongly associated with rebleeding (odds ratio 2.23, 95% CI 1.22-4.07, P=0.01, up to day 30) and mortality (odds ratio 3.06, 95% CI 1.29-7.26, P=0.01). Although mortality has improved following acute variceal haemorrhage, rebleeding rates remain appreciably high. There are notable deficiencies in the use of vasopressors and endoscopic therapy. More work is needed to understand the optimum transfusion strategies. Better risk stratification tools are required to identify patients needing more intensive support.

    These updated guidelines on the management of variceal haemorrhage have been commissioned by the Clinical Services and Standards Committee (CSSC) of the British Society of Gastroenterology (BSG) under the auspices of the liver section of the BSG. The original guidelines which this document supersedes were written in 2000 and have undergone extensive revision by 13 members of the Guidelines Development Group (GDG). The GDG comprises elected members of the BSG liver section, representation from British Association for the Study of the Liver (BASL) and Liver QuEST, a nursing representative and a patient representative. The quality of evidence and grading of recommendations was appraised using the AGREE II tool. The nature of variceal haemorrhage in cirrhotic patients with its complex range of complications makes rigid guidelines inappropriate. These guidelines deal specifically with the management of varices in patients with cirrhosis under the following subheadings: (1) primary prophylaxis; (2) acute variceal haemorrhage; (3) secondary prophylaxis of variceal haemorrhage; and (4) gastric varices. They are not designed to deal with (1) the management of the underlying liver disease; (2) the management of variceal haemorrhage in children; or (3) variceal haemorrhage from other aetiological conditions.

    The Rockall risk scoring system uses clinical criteria and endoscopy to identify patients at risk of adverse outcomes after acute upper gastrointestinal haemorrhage. A clinical Rockall score obtained using only the clinical criteria may be able to predict outcome without endoscopy. To validate the clinical Rockall Score in predicting outcome after acute non-variceal upper gastrointestinal haemorrhage. A retrospective observational study of consecutive patients who were admitted with non-variceal acute upper gastrointestinal haemorrhage was undertaken. Medical records were abstracted using a standardised form. 102 cases were identified (51 men and 51 women; mean age 59 years). 38 (37%) patients considered to be at low risk of adverse outcomes (clinical Rockall Score 0) had no adverse outcomes and did not require transfusion. Patients with a clinical Rockall Score of 1-3 had no adverse outcomes, although 13 of 45 (29%) patients required blood transfusions. Clinical Rockall Scores >3 (n = 19) were associated with adverse outcomes (rebleeding in 4 (21%), surgery in 1 (5%) and death in 2 (10%)). The clinical Rockall Score without endoscopy may be a useful prognostic indicator in this cohort of patients with acute non-variceal upper gastrointestinal haemorrhage. This score may reduce the need for urgent endoscopy in low-risk patients, which can instead be carried out on a more elective outpatient basis.

    We report a case of acute purulent meningitis caused by Streptococcus sanguinis after endoscopic ligation for oesophageal variceal haemorrhage in a cirrhotic patient without preceding symptoms of meningitis. Initial treatment with flomoxef failed. The patient was cured after 20 days of intravenous penicillin G. This uncommon infection due to S. sanguinis adds to the long list of infectious complications among patients with oesophageal variceal haemorrhage.

    Cyanoacrylate injection is a recognised endoscopic treatment option for variceal haemorrhage. We describe a 34-year old man with hepatitis B cirrhosis who presented to the hospital with upper gastrointestinal haemorrhage from gastric and oesophageal varices. Haemostasis was achieved via cyanoacrylate injection sclerotherapy and banding. Ten days later, the patient developed acute hypoxia and fever. His chest radiograph showed wide-spread pulmonary shadowing. A non-contrast CT scan confirmed multiple emboli of injected glue material from the varix with parenchymal changes either suggesting acute lung injury or pulmonary oedema. He gradually recovered with supportive treatment and was discharged home. On follow-up, he remained asymptomatic from a chest perspective. This case report discusses the rare complication of pulmonary embolisation of cyanoacrylate glue from variceal injection sites and the diagnostic dilemmas involved. Emphasis is placed on the importance of maintaining high index of clinical suspicion when assessing patients with possible procedure related complications. PMID:25320260

    repeat HVPG six weeks later. In those with elevated pressures, primary medical prophylaxis could be commenced with subsequent close monitoring of HVPG thus negating the need for endoscopy at this point. All patients presenting with variceal haemorrhage should undergo HVPG measurement and those with a gradient greater than 20 mmHg should be considered for early TIPS. By introducing portal pressure studies into a management algorithm for variceal bleeding, the number of endoscopies required for further intervention and follow up can be reduced leading to significant savings in terms of cost and demand on resources.

    To investigate mortality and rebleeding rate and identify associated risk factors at 6 wk and 5 d following acute variceal haemorrhage in patients with liver cirrhosis and schistosomal periportal fibrosis. This is a prospective study conducted during the period from March to December 2014. Patients with portal hypertension presenting with acute variceal haemorrhage secondary to either liver cirrhosis (group A) or schistosomal periportal fibroses (group B) presenting within 24 h of the onset of the bleeding were enrolled in the study and followed for a period of 6 wk. Analysis of data was done by Microsoft Excel and comparison between groups was done by Statistical Package of Social Sciences version 20 to calculate means and find the levels of statistical differences and define the mortality rates, the P value of < 0.05 was considered to be significant. A total of 94 patients were enrolled in the study. Thirty-two patients (34%) had liver cirrhosis (group A) and 62 (66%) patients had periportal fibrosis (group B). Mortality: The 6-wk and 5-d mortality were 53% and 16% respectively in group A compared to 10% and 0% in group B ( P value < 0.000 and < 0.004). In group A; a Child-Turcotte-Pugh class C and rebleeding within 5 d were significantly associated with 5-d mortality ( P value < 0.029 and < 0.049 respectively) and Child- Turcotte-Pugh class C was also a significant risk factor for 6-wk mortality ( P value < 0.018). In group B; mortality was significantly associated with rebleeding within the 6-wk follow-up period and requirement for blood transfusion on admission ( P value < 0.005 and < 0.049). Rebleeding: The 6-wk and 5-d rebleeding rate in group A were 56% and 25% respectively compared to 32% and 3% in group B ( P value < 0.015 and < 0.002). Clinical presentation with encephalopathy was a significant risk factor for 5 d rebleeding in group A ( P value < 0.005) while grade III periportal fibrosis and requirement for blood transfusion on admission were

    We followed 87 cirrhotic patients with esophageal varices and without previous hemorrhage for a mean period of 24 mo to prospectively evaluate the occurance of variceal bleeding within (early) or after (late) 6 mo from entry and the contribution of portal Doppler ultrasound parameters to the prediction of early and late hemorrhage. Clinical, biochemical, endoscopic and portal Doppler ultrasound parameters were recorded at entry. Variceal bleeding occurred in 22 patients (25.3%). Nine (40.9%) bled within the first 6 mo. Cox regression analysis identified variceal size, cherry-red spots, serum bilirubin and congestion index of the portal vein (the ratio of portal vein [cross-sectional area] and portal blood flow velocity) as the only independent predictors of first variceal hemorrhage. Discriminant analysis was used to find the prognostic index cut off points to identify patients who bled within 6 mo (prognostic group 1) or after 6 mo (prognostic group 2) or remained free of bleeding (prognostic group 3). The cumulative proportion of patients correctly classified was 73% in prognostic group 1, 47% in prognostic group 2 and more than 80% in prognostic group 3. The addition of Doppler ultrasound flowmetry to clinical, biochemical and endoscopic parameter only improved the classification of patients with early bleeding. PMID:9184882

    Acute variceal bleeding (AVB) is the most common cause of upper gastrointestinal hemorrhage in patients with cirrhosis. Advances in the management of AVB have resulted in decreased mortality. To minimize mortality, a multidisciplinary approach addressing airway safety, prompt judicious volume resuscitation, vasoactive and antimicrobial pharmacotherapy, and early endoscopy to obliterate varices is necessary. Placement of a transjugular intrahepatic portosystemic shunt (TIPS) has been used as rescue therapy for patients failing initial attempts at hemostasis. Patients who have a high likelihood of failing initial attempts at hemostasis may benefit from a more aggressive approach using TIPS earlier in their management. Copyright © 2014 Elsevier Inc.

    In patients with upper gastrointestinal bleeding (UGIB), identifying those with esophageal variceal hemorrhage prior to endoscopy would be clinically useful. This retrospective study of a large cohort of patients with UGIB used logistic regression analyses to evaluate the platelet count, aspartate aminotransferase (AST) to platelet ratio index (APRI), AST to alanine aminotransferase (ALT) ratio (AAR) and Lok index (all non-invasive blood markers) as predictors of variceal bleeding in (1) all patients with UGIB and (2) patients with cirrhosis and UGIB. 2233 patients admitted for UGIB were identified; 1034 patients had cirrhosis (46%) and of these, 555 patients (54%) had acute UGIB due to esophageal varices. In all patients with UGIB, the platelet count (cut-off 122,000/mm(3)), APRI (cut-off 5.1), AAR (cut-off 2.8) and Lok index (cut-off 0.9) had area under the curve (AUC)s of 0.80 0.82, 0.64, and 0.80, respectively, for predicting the presence of varices prior to endoscopy. To predict varices as the culprit of bleeding, the platelet count (cut-off 69,000), APRI (cut-off 2.6), AAR (cut-off 2.5) and Lok Index (0.90) had AUCs of 0.76, 0.77, 0.57 and 0.73, respectively. Finally, in patients with cirrhosis and UGIB, logistic regression was unable to identify optimal cut-off values useful for predicting varices as the culprit bleeding lesion for any of the non-invasive markers studied. For all patients with UGIB, non-invasive markers appear to differentiate patients with varices from those without varices and to identify those with a variceal culprit lesion. However, these markers could not distinguish between a variceal culprit and other lesions in patients with cirrhosis. Copyright © 2016 American Federation for Medical Research.

    Variceal upper gastrointestinal bleeding (UGIB) can trigger acute hypoxic hepatitis (AHH). The aim of this study was to analyse the incidence, associated risk factors and mortality of AHH after variceal UGIB. Retrospective study of cirrhotic patients with variceal UGIB, classified into 2 groups according to the development of AHH. AHH was diagnosed when AST and ALT reached levels 10 times above the upper limit of normal, after ruling out other causes of hepatitis. The standard initial treatment consisted of haemodynamic support, emergency endoscopy with rubber band ligation, somatostatin and antibiotics. In the case of failure of primary haemostasis, a transjugular intrahepatic portosystemic shunt (TIPS) was implanted. Both groups (AHH and non-AHH) were compared. Sixty-eight cirrhotic patients with variceal UGIB admitted to the gastroenterology department of Hospital Ramón y Cajal between January 2007 and March 2012 were analysed. Eleven of these patients (16.2%) developed AHH. Univariate analysis showed the following items as risk factors: diabetes (OR: 7.5; CI: 1.9-29), shock (OR: 8.5; CI: 2.06-34) and persistent bleeding (OR: 9.0, CI: 1.6-49, P=.03). However, multivariate analysis confirmed only diabetes (OR: 8.61; CI: 1.4-52.5) and shock (OR: 7.58; CI: 1.26-45.51) as risk factors. Mortality rate in the AHH group was 45%, compared to 10.5% in the non-HAA group (P=.012). AHH after variceal UGIB occurred in 16.2% of cirrhotic patients and was associated with a poorer prognosis, with a mortality rate of 45%. Our findings suggest that diabetes and shock are risk factors for the development of AHH. Early identification of at-risk patients could therefore help prevent AHH.

    Several clinical events have a rhythmicity over the 24 h period. We assessed the presence of periodic rhythm in the occurrence of haematemesis in patients with liver cirrhosis under different daylight regimens, namely during standard time and during daylight savings. Over a 48 month period there were 212 consecutive admissions of 118 cirrhotics with variceal bleeding. Complete data were available for 181 episodes of bleeding: 121 (66.9%) started with haematemesis and 60 (33.1%) started with melaena. One hundred and two (56%) episodes occurred during daylight savings and 79 (44%) occurred during standard time. The cosinor test showed a 24 h biphasic peak for the occurrence of haematemesis (09.45 and 21.45 h). Moreover, a biphasic diurnal asymmetric frequency was also found by multiple component rhythmometry. The time peaks of onset of variceal haemorrhage did not change significantly during standard time and daylight savings. Patients with more than one haematemesis episode significantly bled over the same time interval. The present study confirms that over the 24 h period variceal bleeding in cirrhotic patients occurs with a predictable rhythmicity that does not seem to be under the control of the light-dark cycle. The finding of a chronorisk for variceal haemorrhage addresses specific questions for pathophysiological studies as well as for new treatment strategies.

    Variceal bleeding (VB) is the main cause of death among cirrhotic patients. About 30-50% of early rebleeding is encountered few days after the acute episode of VB. It is necessary to stratify patients with high risk of very early rebleeding (VER) for more aggressive therapies. However, there are few and incompletely understood prognostic models for this purpose. To determine the risk factors associated with VER after an acute VB. Assessment and comparison of a novel prognostic model generated by Classification and Regression Tree Analysis (CART) with classic-used models (MELD and Child-Pugh [CP]). Sixty consecutive cirrhotic patients with acute variceal bleeding. CART analysis, MELD and Child-Pugh scores were performed at admission. Receiver operating characteristic (ROC) curves were constructed to evaluate the predictive performance of the models. Very early rebleeding rate was 13%. Variables associated with VER were: serum albumin (p = 0.027), creatinine (p = 0.021) and transfused blood units in the first 24 hrs (p = 0.05). The area under the ROC for MELD, CHILD-Pugh and CART were 0.46, 0.50 and 0.82, respectively. The value of cut analyzed by CART for the significant variables were: 1) Albumin 2.85 mg/dL, 2) Packed red cells 2 units and 3) Creatinine 1.65 mg/dL the ABC-ROC. Serum albumin, creatinine and number of transfused blood units were associated with VER. A simple CART algorithm combining these variables allows an accurate predictive assessment of VER after acute variceal bleeding.

    The purpose was to study the prevalence and predisposing factors of brain lesions in survivors of acute methanol poisoning. Clinical data on 106 patients with methanol poisoning were collected during the Czech mass poisoning outbreak. Of 83 survivors, in 46 (55%) patients, follow-up examinations including magnetic resonance imaging of brain (MR) were performed 3-8 and 24-28 months after discharge from the hospital. Of 46 patients with a median age of 49 (interquartile range, 35-57) years, 24 (52%) patients had a total of 40 abnormal brain findings with haemorrhagic lesions detected in 15 (33%) and non-haemorrhagic lesions found in 9 (19%) patients. The patients with haemorrhagic brain lesions were more acidemic (lower arterial blood pH, higher base deficit) and had higher glycaemia and lactacidaemia on admission than those without haemorrhages (all p < 0.05). Thirteen of 32 (41%) of patients with systemic anticoagulation and 2 of 14 (14%) of patients without it had haemorrhagic lesions (p = 0.080). Bleeding complications during the treatment occurred in 4 of 15 (27%) patients, and 5 of 15 (33%) patients had conditions predisposing to haemorrhage in the group with haemorrhagic lesions. In three cases with a series of computer tomography (CT)/MR performed during hospitalization, the necrotic lesions in the brain remained non-haemorrhagic during hospitalization and haemorrhagic lesions were detected on the follow-up MR examinations only. No association between brain haemorrhages and systemic anticoagulation during dialysis was found: brain haemorrhages might occur in severely poisoned patients treated without systemic anticoagulation, whereas treatment with high doses of heparin might not lead to brain haemorrhages. © 2016 Nordic Association for the Publication of BCPT (former Nordic Pharmacological Society).

    Bleeding from gastroesophageal varices is a serious complication in patients with liver cirrhosis and portal hypertension. Although there has been significance improvement in the prognosis of variceal bleeding with advancement in diagnostic and therapeutic modalities for its management, mortality rate still remains high. Therefore, appropriate prevention and rapid, effective management of bleeding from gastroesophageal varices is very important. Recently, various studies about management of gastoesophageal varices, including prevention of development and aggravation of varices, prevention of first variceal bleeding, management of acute variceal bleeding, and prevention of variceal rebleeding, have been published. The present article reviews published articles and practice guidelines to present the most optimal management of patients with gastroesophageal varices. PMID:29249128

    to evaluate the efficacy of various indicators in predicting short- and long-term survival in patients with cirrhosis and acute variceal bleeding. prognostic indicators were calculated for a cohort of 201 cirrhotic patients with acute variceal bleeding hospitalized in our center, a third-level teaching hospital. The studied variables were: age, sex, etiology of cirrhosis, endoscopic findings, previous variceal bleeding episodes, human immunodeficiency virus (HIV) infection, hepatocellular carcinoma (HCC), infection during episode, and Child-Turcotte-Pugh (CTP) and Model for End-stage Liver Disease (MELD) scores within 24 hours of bleeding onset. Patients were followed up for at least 6 months until death, liver transplantation, or end of observation. median follow-up was 66.85 weeks (range 0-432.4). The 6-week, 3-month, 12-month and 36-month mortality rates were 22.9, 24.9, 34.3, and 39.8%, respectively. Age >= 65 years, presence of HCC, CTP score >=10, and MELD score >= 18 were the variables associated with mortality in the multivariate analysis. The accuracy of MELD scores as predictors of 6-week, 3-month, 12-month, and 36-month mortality was better than that of CTP scores (c-statistics: 6 week MELD 0.804, CTP 0.762; 3-month MELD 0.794, CTP 0.760; 12-month MELD 0.766, CTP 0.741; 36 month MELD 0.737, CTP 0.717). MELD and CTP scores together with age and a diagnosis of hepatocellular carcinoma are useful indicators to assess the short- and long-term prognosis of patients with acute variceal bleeding.

    The effect of pharmacological constriction of the lower oesophageal sphincter (LOS) on oesophageal varices was investigated in an experimental study followed by a controlled clinical trial. In the experimental study intravariceal pressure was measured just above the LOS in 11 patients before and after constricting the LOS by intravenous pentagastrin. Intravariceal pressure fell from a mean of 23 (range 12-36) mmHg to 4 (range 0-7) mmHg (p less than 0.001). This marked pressure drop indicated the considerable compression of varices that occurred within the LOS. A prospective controlled clinical trial examined whether LOS constriction (effected by the longer acting metoclopramide) would compress varices sufficiently to arrest active variceal bleeding originating from the lowest 2 cm oesophagus--the area encircled by the LOS. Of 11 patients who received metoclopramide, 10 stopped bleeding compared with four of the 11 who received placebo (p less than 0.01). Pharmacological constriction of the LOS appears to offer a new and effective approach for arresting active bleeding from oesophageal varices. PMID:3044932

    Acute non-traumatic convexity subarachnoid haemorrhage (cSAH) is increasingly recognised in cerebral amyloid angiopathy (CAA). We investigated: (a) the overlap between acute cSAH and cortical superficial siderosis-a new CAA haemorrhagic imaging signature and (b) whether acute cSAH presents with particular clinical symptoms in patients with probable CAA without lobar intracerebral haemorrhage. MRI scans of 130 consecutive patients meeting modified Boston criteria for probable CAA were analysed for cortical superficial siderosis (focal, ≤3 sulci; disseminated, ≥4 sulci), and key small vessel disease markers. We compared clinical, imaging and cortical superficial siderosis topographical mapping data between subjects with versus without acute cSAH, using multivariable logistic regression. We included 33 patients with probable CAA presenting with acute cSAH and 97 without cSAH at presentation. Patients with acute cSAH were more commonly presenting with transient focal neurological episodes (76% vs 34%; p<0.0001) compared with patients with CAA without cSAH. Patients with acute cSAH were also more often clinically presenting with transient focal neurological episodes compared with cortical superficial siderosis-positive, but cSAH-negative subjects with CAA (76% vs 30%; p<0.0001). Cortical superficial siderosis prevalence (but no other CAA severity markers) was higher among patients with cSAH versus those without, especially disseminated cortical superficial siderosis (49% vs 19%; p<0.0001). In multivariable logistic regression, cortical superficial siderosis burden (OR 5.53; 95% CI 2.82 to 10.8, p<0.0001) and transient focal neurological episodes (OR 11.7; 95% CI 2.70 to 50.6, p=0.001) were independently associated with acute cSAH. This probable CAA cohort provides additional evidence for distinct disease phenotypes, determined by the presence of cSAH and cortical superficial siderosis. © Article author(s) (or their employer(s) unless otherwise stated in the

  20. Diagnosis and therapy of non-variceal upper gastrointestinal bleeding

    PubMed Central

    2015-01-01

    Non-variceal upper gastrointestinal bleeding (UGIB) is defined as bleeding proximal to the ligament of Treitz in the absence of oesophageal, gastric or duodenal varices. The clinical presentation varies according to the intensity of bleeding from occult bleeding to melena or haematemesis and haemorrhagic shock. Causes of UGIB are peptic ulcers, Mallory-Weiss lesions, erosive gastritis, reflux oesophagitis, Dieulafoy lesions or angiodysplasia. After admission to the hospital a structured approach to the patient with acute UGIB that includes haemodynamic resuscitation and stabilization as well as pre-endoscopic risk stratification has to be done. Endoscopy offers not only the localisation of the bleeding site but also a variety of therapeutic measures like injection therapy, thermocoagulation or endoclips. Endoscopic therapy is facilitated by acid suppression with proton pump inhibitor (PPI) therapy. These drugs are highly effective but the best route of application (oral vs intravenous) and the adequate dosage are still subjects of discussion. Patients with ulcer disease are tested for Helicobacter pylori and eradication therapy should be given if it is present. Non-steroidal anti-inflammatory drugs have to be discontinued if possible. If discontinuation is not possible, cyclooxygenase-2 inhibitors in combination with PPI have the lowest bleeding risk but the incidence of cardiovascular events is increased. PMID:26558151

    Background. The Rockall, Glasgow-Blatchford, and AIMS65 are useful and validated scoring systems for predicting the outcomes of patients with nonvariceal gastrointestinal bleeding. However, there are no validated evidence for using them to predict outcomes on variceal bleeding. The aim of this study was to evaluate and compare the prognostic accuracy of different nonvariceal bleeding scores with other liver-specific scoring systems in cirrhotic patients. A retrospective multicenter study that included 160 cirrhotic patients with acute variceal bleeding. The AUROC's to predict in-hospital mortality, and rebleeding, were analyzed for each scoring system. Overall in-hospital mortality occurred in 13% and in-hospital rebleeding in 12% of patients. The systems with the best AUROC value for predicting mortality were MELD (0.828; 95% CI 0.748-0.909), and AIMS65 (0.817; 95% CI 0.724-0.909). The best score systems for predicting rebleeding were Glasgow-Blatchford (0.756; 95% CI 0.640- 0.827), and Rockall (0.691; 95% CI 0.580-0.802). In addition to liver-specific scores, the AIMS65 score is accurate for predicting in-hospital mortality in cirrhotic patients with acute variceal bleeding. Other scoring systems might be useful for predicting significant clinical outcomes in these patients.

    Data regarding the efficacy of the Glasgow Blatchford score (GBS), full Rockall score (FRS) and pre-endoscopic Rockall scores (PRS) in comparing non-variceal and variceal upper gastrointestinal bleeding (UGIB) are limited. Our aim was to determine the performance of these three risk scores in predicting the need for treatment, mortality, and re-bleeding among patients with non-variceal and variceal UGIB. During January, 2010 and September, 2011, patients with UGIB from 11 hospitals were prospectively enrolled. The GBS, FRS, and PRS were calculated. Discriminative ability for each score was assessed using the receiver operated characteristics curve (ROC) analysis. A total of 981 patients presented with acute UGIB, 225 patients (22.9%) had variceal UGIB. The areas under the ROC (AUC) of the GBS, FRS, and PRS for predicting the need for treatment were 0.77, 0.69, and 0.61 in non-variceal versus 0.66, 0.66, and 0.59 in variceal UGIB. The AUC for predicting mortality and re-bleeding during admission were 0.66, 0.80, and 0.76 in non-variceal versus 0.63, 0.57, and 0.63 in variceal UGIB. AUC score was not statistically significant for predicting need for therapy and clinical outcome in variceal UGIB. The GBS ≤ 2 and FRS ≤ 1 identified low-risk non-variceal UGIB patients for death and re-bleeding during hospitalization. In contrast to non-variceal UGIB, the GBS, FRS, and PRS were not precise scores for assessing the need for therapy, mortality, and re-bleeding during admission in variceal UGIB. © 2015 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

    To evaluate prevalence of enteric viruses in healthy dogs and to compare it with prevalences in dogs with acute haemorrhagic diarrhoea. Faecal samples were collected from 200 healthy dogs and examined by electron microscopy for presence of viral particles. Data were compared with viral prevalences that had been determined retrospectively by electron microscopy for 936 dogs with acute haemorrhagic diarrhoea. There were significantly more negative faecal samples among the healthy dogs (82.0 per cent) compared with 55.8 per cent in dogs with acute haemorrhagic diarrhoea (P<0.001). With a prevalence of 17.5 per cent, significantly more healthy dogs were shedding coronavirus compared with 11.6 per cent in dogs with acute haemorrhagic diarrhoea (P=0.034). Parvovirus was only detected in one healthy dog (0.5 per cent), thus with a prevalence that was significantly lower than 16.0 per cent detected in the dogs with acute haemorrhagic diarrhoea (P<0.001). Paramyxovirus was not found in any of the healthy dogs but was found in 9.3 per cent of dogs with acute haemorrhagic diarrhoea (P<0.001). Results suggest that shedding of parvovirus and paramyxovirus is strongly associated with acute haemorrhagic diarrhoea. However, coronavirus seems to be even more prevalent among healthy dogs, raising the need for further studies to investigate the strain-associated pathogenicity of this virus.

    Although rare, non-traumatic hepatic haemorrhage is a known complication of liver tumors. In cases where the haemorrhage is the first clinical event, diagnostic work-up is critical. This retrospective study was conducted between July 2001 and March 2011. Acute phase CT-scan and MRI imaging in patients diagnosed with non-traumatic liver hematomas were interpreted with particular attention to the radio-semiotic characteristics of hematomas and liver lesions. Those findings were then confronted to the patients' final diagnoses. Twelve patients were included (mean age of 42 years). In seven of them a suspect liver lesion was discovered in the acute CT-Scan or MRI imaging. All lesions were strongly hyper vascular.The haemorrhage revealed hepatocarcinoma in four patients, liver adenoma in two and focal nodular hyperplasia in an other. It is important in spontaneous liver haemorrhage to consider the high probability of hepatocarcinoma or potentially malignant lesions even when the patient has no known hepatic disorders, and especially in young patients. The results of this study show that imaging is a key issue at the acute phase of inaugural non-traumatic hepatic haemorrhages and requires a simple but complete triphasic injected protocol.

It usually occurs in children younger than 2 years of age, with spontaneous recovery occurring within a few weeks. A history of recent upper respiratory or urinary tract infections or immunisation is found in most patients. Although Mycoplasma pneumoniae has been linked to a wide array of skin eruptions or diseases, it is not recognised as a possible cause of acute haemorrhagic oedema of infancy.

    Acute non-variceal upper gastrointestinal bleeding (ANVUGIB) is one of the most common medical emergencies in China and worldwide. In 2009, we published the "Guidelines for the diagnosis and treatment of acute non-variceal upper gastrointestinal bleeding" for the patients in China; however, during the past years numerous studies on the diagnosis and treatment of ANVUGIB have been conducted, and the management of ANVUGIB needs to be updated. The guidelines were updated after the databases including PubMed, Embase and CNKI were searched to retrieve the clinical trials on the management of ANVUGIB. The clinical trials were evaluated for high-quality evidence, and the advances in definitions, diagnosis, etiology, severity evaluation, treatment and prognosis of ANVUGIB were carefully reviewed, the recommendations were then proposed. After several rounds of discussions and revisions among the national experts of digestive endoscopy, gastroenterology, radiology and intensive care, the 2015 version of "Guidelines for the diagnosis and treatment of acute non-variceal upper gastrointestinal bleeding" was successfully developed by the Chinese Journal of Internal Medicine, National Medical Journal of China, Chinese Journal of Digestion and Chinese Journal of Digestive Endoscopy. It shall be noted that although much progress has been made, the clinical management of ANVUGIB still needs further improvement and refinement, and high-quality randomized trials are required in the future. © 2016 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.

    Bleeding from esophageal varices is a leading cause of death in alcoholic cirrhotic patients. The aim of the present single-center study was to identify risk factors predictive of variceal rebleeding and death within 6 weeks of initial treatment. Univariate and multivariate analyses were performed on 310 prospectively documented alcoholic cirrhotic patients with acute variceal hemorrhage (AVH) who underwent 786 endoscopic variceal injection treatments between January 1984 and December 2006. All injections were administered during the first 6 weeks after the patients were treated for their first variceal bleed. Seventy-five (24.2%) patients experienced a rebleed, 38 within 5 days of the initial treatment and 37 within 6 weeks of their initial treatment. Of the 15 variables studied and included in a multivariate analysis using a logistic regression model, a bilirubin level >51 mmol/l and transfusion of >6 units of blood during the initial hospital admission were predictors of variceal rebleeding within the first 6 weeks. Seventy-seven (24.8%) patients died, 29 (9.3%) within 5 days and 48 (15.4%) between 6 and 42 days after the initial treatment. Stepwise multivariate logistic regression analysis showed that six variables were predictors of death within the first 6 weeks: encephalopathy, ascites, bilirubin level >51 mmol/l, international normalized ratio (INR) >2.3, albumin <25 g/l, and the need for balloon tube tamponade. Survival was influenced by the severity of liver failure, with most deaths occurring in Child-Pugh grade C patients. Patients with AVH and encephalopathy, ascites, bilirubin levels >51 mmol/l, INR >2.3, albumin <25 g/l and who require balloon tube tamponade are at increased risk of dying within the first 6 weeks. Bilirubin levels >51 mmol/l and transfusion of >6 units of blood were predictors of variceal rebleeding.

    Endoscopic variceal ligation (EVL) is widely used to prevent esophageal variceal bleeding in patients with advanced cirrhosis. However, the safety and efficacy of EVL in this setting have not been clearly established. This study included 300 adult patients with cirrhosis on our liver transplant waitlist who underwent upper gastrointestinal endoscopy. Esophageal varices deemed to be at high risk of bleeding were banded until eradication or transplantation. A retrospective review of patient notes and endoscopy databases was undertaken, and the number of banding episodes, complications, and patient outcomes were recorded. Forty-two of 300 patients presented with or had previous variceal bleeding prior to referral and were excluded from the analysis. Of the remaining 258 patients, 101 underwent a total of 259 banding episodes (2.6 per patient) with a median follow-up post-banding of 18.4 months per patient (a total of 150 patient years). Failed prophylaxis occurred in 2 patients (2%), and there were 3 episodes (1.2%) of acute hematemesis from band-induced ulceration. One patient (1%) had mild esophageal stricturing post-banding without dysphagia. Four of 36 patients (11%) previously found to have moderately sized or larger varices that were not banded presented with hematemesis due to variceal bleeding and were subsequently banded. None of the patients that received banding died because of bleeding or failed to receive a transplant as a result of banding complications. This study shows that in liver transplant candidates, EVL is highly effective in preventing first variceal bleed. Although banding carries a small risk of band-induced bleeding, this rate is low in comparison with the predicted rate of variceal bleeding in this population.

    To assess changes in practice and outcome in acute upper gastrointestinal haemorrhage following the feedback of data, the reemphasis of national guidelines, and specific recommendations following an initial survey. A prospective, multicentre, audit cycle. Forty five hospitals from three health regions participated in two phases of the audit cycle. Phase I: 2332 patients with acute upper gastrointestinal haemorrhage; phase II: 1625 patients with upper gastrointestinal haemorrhage. Patients were evaluated with respect to management (with reference to the recommendations in the national guidelines), mortality, and length of hospital stay. Following the distribution of data from the first phase of the National Audit and the formulation of specific recommendations for improving practice, the proportion of hospitals with local guidelines or protocols for the management of upper gastrointestinal haemorrhage rose from 71% (32/45) to 91% (41/45); 12 of the 32 hospitals with guidelines during the first phase revised their guidelines following the initial survey. There was a small but significant increase in the proportion of all patients who underwent endoscopy (from 81% to 86%), the proportion who underwent endoscopy within 24 hours of admission (from 50% to 56%), and the use of central venous pressure monitoring in patients with organ failure requiring blood transfusion or those with profound shock (from 30% to 43%). There was, however, no change in the use of high dependency beds or joint medical/surgical management in high risk cases. There was no significant change in crude or risk standardised mortality (13.4% in the first phase and 14.4% in the second phase). Although many of the participating hospitals have made efforts to improve practice by producing or updating guidelines or protocols, there has been only a small demonstrable change in some areas of practice during the National Audit. The failure to detect any improvement in mortality may reflect this lack of

    Acute liver failure in neonates is rare and is frequently associated with an unfavourable outcome. There is no curative treatment other than liver transplantation. Screening for viral, metabolic, toxic or vascular disease is essential to assess the prognosis and to guide specific treatment. Hepatic haemorrhage in neonates is often associated with bacterial infection, trauma and coagulopathies. We present a unique case of neonatal acute liver failure and multifocal massive haemorrhagic intrahepatic lesions of traumatic origin, documented by US and MRI. The patient made a spontaneous recovery. Clinical, biological and imaging outcome was excellent despite the apparent severity of the initial features. The only possible aetiology was a difficult caesarean delivery for mild fetal macrosomia.

    Acute upper gastrointestinal bleeding (AUGIB) in cirrhotic patients occurs mainly from esophageal and gastric varices; however, quite a large number of cirrhotic patients bleed from other sources as well. The aim of the present work is to determine the prevalence of non-variceal UGIB as well as its different causes among the cirrhotic portal hypertensive patients in Nile Delta. Emergency upper gastrointestinal (UGI) endoscopy for AUGIB was done in 650 patients. Out of these patients, 550 (84.6%) patients who were proved to have cirrhosis were the subject of the present study. From all cirrhotic portal hypertensive patients, 415 (75.5%) bled from variceal sources (esophageal and gastric) while 135 (24.5%) of them bled from non-variceal sources. Among variceal sources of bleeding, esophageal varices were much more common than gastric varices. Peptic ulcer was the most common non-variceal source of bleeding. Non-variceal bleeding in cirrhosis was not frequent, and sources included peptic ulcer, portal hypertensive gastropathy, and erosive disease of the stomach and duodenum.

    To identify the best time-frame for defining bleeding-related death after variceal bleeding in patients with cirrhosis. Prospective long-term evaluation of a cohort of 155 patients admitted with variceal bleeding. Eight medical departments in seven hospitals in north-eastern Italy. Non-linear regression analysis of a hazard curve for death, and Cox's multiple regression analyses using different zero-time points. Cumulative hazard plots gave two slopes, the first corresponding to the risk of death from acute bleeding, the second a baseline risk of death. The first 30 days were outside the confidence limits of the regression curve for the baseline risk of death. Using Cox's regression analysis, the significant predictors of overall mortality risk were balanced between factors related to severity of bleeding and those related to severity of liver disease. If only deaths occurring after 30 days were considered, only predictors related to the severity of liver disease were found to be of importance. Thirty days after bleeding is considered to be a reasonable time-frame for the definition of bleeding-related death in patients with cirrhosis and variceal bleeding.

    To quantify and compare portosystemic pressure gradients (PSGs) between bleeding esophageal varices (EV) and gastric varices (GV). In a single-center, retrospective study, 149 patients with variceal bleeding (90 men, 59 women, mean age 52 y) with EV (n = 69; 46%) or GV (n = 80; 54%) were selected from 320 consecutive patients who underwent successful transjugular intrahepatic portosystemic shunt (TIPS) creation from 1998 to 2016. GV were subcategorized using the Sarin classification as gastroesophageal varices (GEV) (n = 57) or isolated gastric varices (IGV) (n = 23). PSG before TIPS was measured from the main portal vein to the right atrium. PSGs were compared across EV, GEV, and IGV groups using 1-way analysis of variance. Overall mean baseline PSG was 21 mm Hg ± 6. PSG was significantly higher in patients with EV versus GV (23 mm Hg vs 19 mm Hg; P < .001). Mean PSG was highest among EV (23 mm Hg) with lower PSGs identified for GEV (20 mm Hg) and IGV (16 mm Hg); this difference was statistically significant (P < .001). Among 95 acute bleeding cases, a similar pattern was evident (EV 23 mm Hg vs GEV mm Hg 20 vs IGV 17 mm Hg; P < .001). At baseline PSG < 12 mm Hg, 13% (3/23) of IGV bled versus 9% (5/57) of GEV and 3% (2/69) of EVs (P = .169). Mean final PSG after TIPS was 8 mm Hg (IGV 6 mm Hg vs EV and GEV 8 mm Hg; P = .005). GV bleed at lower PSGs than EV. EV, GEV, and IGV bleeding is associated with successively lower PSGs. These findings highlight distinct physiology, anatomy, and behavior of GV compared with EV.

    No prospective studies including large numbers of dogs with acute haemorrhagic diarrhoea syndrome (AHDS) are published so far. The aim of this case-control study was to describe signalment, history, clinical signs, laboratory values and course of disease in dogs with AHDS. Dogs (108) with idiopathic acute haemorrhagic diarrhoea (<3 days) were prospectively enrolled. Clinical assessment was performed by calculation of the 'AHDS index' (0-18). The hospital population and 21 healthy dogs served as control groups. Dogs with AHDS had a significantly lower body weight (median 9.8 kg) and age (median five years) than other dogs of the hospital population (20 kg; 10 years) (P<0.001). Predisposed breeds were Yorkshire terrier, miniature pinscher, miniature schnauzer and Maltese. The syndrome was more likely to occur during winter. Vomiting preceded the onset of bloody diarrhoea in 80 per cent of dogs and haematemesis was observed in half of those cases. Median AHDS index at presentation was 12 (range 3-17). Haematocrit was generally high (median 57.1 per cent; range 33-76 per cent), but exceeded 60 per cent only in 31.4 per cent of dogs. Haematocrit of 48.1 per cent of dogs was above reference range, as was monocyte (50.0 per cent), segmented (59.6 per cent) and band neutrophil count (45.2 per cent). A rapid clinical improvement occurred during the first 48 hours. British Veterinary Association.

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

    Summary Background It is often assumed that blood pressure increases acutely after major stroke, resulting in so-called post-stroke hypertension. In view of evidence that the risks and benefits of blood pressure-lowering treatment in acute stroke might differ between patients with major ischaemic stroke and those with primary intracerebral haemorrhage, we compared acute-phase and premorbid blood pressure levels in these two disorders. Methods In a population-based study in Oxfordshire, UK, we recruited all patients presenting with stroke between April 1, 2002, and March 31, 2012. We compared all acute-phase post-event blood pressure readings with premorbid readings from 10-year primary care records in all patients with acute major ischaemic stroke (National Institutes of Health Stroke Scale >3) versus those with acute intracerebral haemorrhage. Findings Of 653 consecutive eligible patients, premorbid and acute-phase blood pressure readings were available for 636 (97%) individuals. Premorbid blood pressure (total readings 13 244) had been measured on a median of 17 separate occasions per patient (IQR 8–31). In patients with ischaemic stroke, the first acute-phase systolic blood pressure was much lower than after intracerebral haemorrhage (158·5 mm Hg [SD 30·1] vs 189·8 mm Hg [38·5], p<0·0001; for patients not on antihypertensive treatment 159·2 mm Hg [27·8] vs 193·4 mm Hg [37·4], p<0·0001), was little higher than premorbid levels (increase of 10·6 mm Hg vs 10-year mean premorbid level), and decreased only slightly during the first 24 h (mean decrease from <90 min to 24 h 13·6 mm Hg). By contrast with findings in ischaemic stroke, the mean first systolic blood pressure after intracerebral haemorrhage was substantially higher than premorbid levels (mean increase of 40·7 mm Hg, p<0·0001) and fell substantially in the first 24 h (mean decrease of 41·1 mm Hg; p=0·0007 for difference from decrease in ischaemic stroke).

    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.

    Microvascular thrombosis is a critical event in severe acute pancreatitis. Human recombinant activated protein C (Xigris®, Eli Lilly, Indianapolis, IN, USA) modulates the interplay between pro-inflammatory and pro-coagulant pathways and maintains microvascular patency. However, the anticoagulant properties of Xigris® may precipitate bleeding from the inflamed pancreas. This study tests the hypothesis that Xigris® can ameliorate experimental acute pancreatitis without causing pancreatic haemorrhage. Sprague Dawley rats were allocated as follows: Group 1: control (n=7); Group 2: acute pancreatitis (n=6); Group 3: administration of Xigris® 500 µg/kg body weight before induction of acute pancreatitis (n=6); and Group 4: Administration of Xigris® 500 µg/kg body weight 30 minutes after induction of acute pancreatitis (n=6). Acute pancreatitis was induced by intraperitoneal administration of L-arginine 300 mg/100 g body weight. Animals were sacrificed at 48 hours and biochemical, haematological, and histological markers of pancreatic haemorrhage and inflammation assessed. Median lipase in animals with acute pancreatitis was 10 U/mL (range: 7-16 U/mL) compared to 5.5 (range: 3-8 U/mL) in controls (P=0.028). Lipase was also elevated in animals given Xigris® both before (12 U/mL, range: 8-22 U/mL; P=0.031 vs. control group) and after (46 U/mL, range: 9-71 U/mL; P=0.015 vs. control group) induction of acute pancreatitis). Haemoglobin levels were similar among all groups (P=0.323). There was no histological evidence of pancreatic haemorrhage in animals treated with Xigris®. Pre-treatment with Xigris® was associated with a significant reduction in pancreatic injury. This effect was absent when Xigris® was administered after induction of acute pancreatitis. Xigris® did not lead to pancreatic haemorrhage in experimental acute pancreatitis. Administration of Xigris® prior to induction of acute pancreatitis was associated with amelioration of injury. This effect was

    Acute retrobulbar haemorrhage (ARBH) is a rare ophthalmic emergency observed following blunt eye trauma. Multiple trauma and loss of consciousness can hide symptoms of ARBH. Rapid diagnosis and immediate lateral canthotomy and cantholysis must be performed to prevent permanent visual loss in patients. Medical treatment can be added to surgical therapy. Lateral canthotomy and cantholysis are simple procedures that can be performed by emergency physicians. In this report, it was aimed to present a case with post-traumatic ARBH and provide general knowledge about the diagnosis, follow-up and treatment of ARBH.

    Haemorrhagic transformations are pejorative for patients with acute ischaemic stroke (AIS). We estimated flat-panel CT performances to detect brain parenchymal hyperdense lesions immediately after mechanical thrombectomy directly on the angiography table in patients with AIS, and its ability to predict haemorrhagic transformation. We also evaluated an easy-reading protocol for post-procedure flat-panel CT evaluation by clinicians to enable them to determine the potential risk of haemorrhage. Two neuroradiologists retrospectively reviewed post-procedural flat-panel CT and 24 h follow-up imaging. We evaluated hyperdense lesions on flat-panel CT to predict the occurrence of haemorrhagic transformation within 24 h detected with conventional imaging. Of 63 patients, 60.3% presented post-procedural parenchymal hyperdensity and 54.0% had haemorrhagic transformation. Significantly more patients with hyperdense lesions on post-thrombectomy flat-panel CT presented haemorrhagic transformation (84.2% vs 8.0%; p<0.0001). No significant haemorrhagic transformations were detected for patients without parenchymal hyperdensity. Sensitivity and specificity of hyperdense lesions on flat-panel CT for the prediction of haemorrhagic transformation were 94.1% (80.3-99.3%) and 79.3% (60.3-92.0%), respectively. The positive and negative predictive values for the occurrence of haemorrhage were 84.2% (68.8-94.0%) and 92.0% (74.0-99.0%), respectively. For significant parenchymal haemorrhage type 2, sensitivity and negative predictive values were 100%. We observed good homogeneity between the different readers. Hyperdensity on post-procedural flat-panel CT was associated with a tendency for higher risk of death and lower risk of good clinical outcome. Flat-panel CT appears to be a good tool to detect brain parenchymal hyperdensities after mechanical thrombectomy in patients with AIS and to predict haemorrhagic transformation.

    Gastric varices that arise secondary to the splenic vein occlusion can result in gastrointestinal hemorrhaging. Endoscopic color Doppler ultrasonography (ECDUS) was performed in 16 patients with gastric varices secondary to splenic vein occlusion. This study retrospectively evaluated the role of ECDUS in the diagnosis of gastric varices secondary to splenic vein occlusion. Thirteen patients had co-existing pancreatic diseases: 8 with chronic pancreatitis, 4 with cancer of the pancreatic body or tail and 1 with severe acute pancreatitis. Of the remaining 3 patients, 1 had myeloproliferative disease, 1 had advanced gastric cancer, and the third had splenic vein occlusion due to an obscure cause. The endoscopic findings of gastric varices were: variceal form (F) classified as enlarged tortuous (F2) in 12 cases and large, coil-shaped (F3) in 4 cases, and positive for erosion or red color sign of the variceal surface in 4 cases and negative in 12 cases. ECDUS color flow images of gastric variceal flow clearly depicted a round fundal region at the center, with varices expanding to the curvatura ventriculi major of the gastric body in all 16 cases. The velocities of F3 type gastric varices were significantly higher than those of the F2 type. The wall thickness of varices positive for erosion or red color sign was significantly less than the negative cases. I conclude that ECDUS color flow images of gastric variceal flow depicted specific findings of gastric varices secondary to splenic vein occlusion at the round fundal region at the center, with varices expanding to the curvatura ventriculi major of the gastric body.

    Gastric varices (GV) occur in 20% of patients with portal hypertension either in isolation or in combination with esophageal varices (EV). There is no consensus for optimum treatment of GV and because they comprise an inhomogeneous entity, accurate classification is vital to determine the appropriate management. Gastroesophageal varices (GOV) are classified as GOV1 (EV extending down to cardia or lesser curve) or GOV2 (esophageal and fundal varices). Isolated gastric varices (IGV) may be located in the fundus (IGV1) or elsewhere in the stomach (IGV2). GV possibly bleed less frequently than EV, but GV bleeding is typically difficult to control, associated with a high risk for rebleeding, and high mortality. Fundal varices, large GV (>5 mm), presence of a red spot, and Child's C liver status are associated with a high risk for bleeding. GOV1 have a much lower risk for bleeding. A portosystemic pressure gradient of > or =12 mm Hg is not necessary for GV bleeding, probably related to the high frequency of spontaneous gastrorenal shunts in these patients. GOV1 should be treated as for EV. First-line treatment of bleeding fundal varices is endoscopic variceal obturation. TIPS is currently second-line acute treatment and is used for prevention of rebleeding. The role of some newer interventional radiologic techniques requires further appraisal. This review describes the pathophysiology, diagnosis, natural history, endoscopic, and interventional radiologic treatment options for GV.

    Variceal hemorrhage is associated with high morbidity and mortality. A balloon tamponade device (BTD), such as the Sengstaken-Blakemore or Minnesota tube, may be used in cases of variceal hemorrhage. While these devices may be effective at controlling acute bleeding, the effect on patient outcomes remains less clear. We sought to describe the number of patients with variceal hemorrhage and a BTD who survive to discharge, survive to one-year, and develop complications related to a BTD. In this retrospective study, we identified patients at a single, tertiary care center who underwent placement of a BTD for upper gastrointestinal hemorrhage between 2003 and 2014. Patient characteristics and outcomes were summarized using descriptive statistics. 34 patients with a BTD were identified. Median age was 57.5 (IQR 47-63) and 76% (26/34) were male. Approximately 59% (20/34) of patients survived to discharge, and 41% (13/32) were alive after one year. Two patients were lost to follow-up. Of those surviving to discharge, 95% (19/20) had undergone transjugular intrahepatic portosystemic shunt (TIPS), while 36% (5/14) of patients who did not survive to discharge had TIPS (p<0.01). One complication, an esophageal perforation, was identified and managed conservatively. In this cohort of patients undergoing BTD placement for variceal hemorrhage, approximately 59% of patients were alive at discharge and 41% were alive after one year. Placement of a BTD as a temporizing measure in the management of acute variceal hemorrhage may be helpful, particularly when utilized as a bridge to more definitive therapy.

    Canine circovirus (CanineCV) has been detected in some dogs with severe haemorrhagic diarrhoea, but its pathogenic role is unclear. This study evaluated a suspected association between the presence of CanineCV and acute haemorrhagic diarrhoea syndrome (AHDS) in dogs. The prevalence of CanineCV in dogs with AHDS was compared with that in healthy dogs and those infected with canine parvovirus (CPV). Additionally, time to recovery and mortality rate were compared between CanineCV-positive and CanineCV-negative dogs. Faecal samples of dogs with AHDS (n=55), healthy dogs (n=66) and dogs infected with CPV (n=54) were examined by two real-time TaqMan PCR assays targeting the replicase and capsid genes of CanineCV. CanineCV was detected in faecal samples of two dogs with AHDS, three healthy controls and seven dogs infected with CPV. Among the three groups, there was no significant difference in prevalence of CanineCV. CPV-infected animals that were coinfected with CanineCV had a significantly higher mortality rate compared with those negative for CanineCV. CanineCV does not appear to be the primary causative agent of AHDS in dogs, but might play a role as a negative co-factor in disease outcome in dogs with CPV infection.

    As no human data exist, we aimed to determine the relation between ambient temperature and volume of perihematomal 'cerebral' edema in acute spontaneous intracerebral haemorrhage (ICH) among Chinese participants of the pilot phase, Intensive Blood Pressure Reduction in Acute Cerebral Haemorrhage Trial (INTERACT1). INTERACT1 was a multicenter, open, blind outcome assessed, randomized controlled trial of intensive (systolic target <140 mmHg) vs. guideline-recommended (systolic target <180 mmHg) blood pressure (BP) lowering in 404 patients with acute ICH. Data on ambient temperature (mean, minimum, maximum, and range) on the day of each participant's ICH obtained from China Meteorological Data Sharing Service System were linked to other data including edema volumes. Multivariable regression analyses were performed to evaluate association between ambient temperature and edema volumes. A generalized linear regression model with a generalized estimating equations approach (GEE) was used to assess any association of ambient temperature and change in edema volume over 72 h. A total of 250 of all 384 Chinese participants had complete data that showed positive associations between ambient temperature (mean and minimum temperatures) and edema volumes at each time point over 72 h after hospital admission (all P < 0·05). All temperature parameters except diurnal temperature range were positively associated with edema volume after adjustment for confounding variables (all P < 0·02). An apparent positive association exists between ambient temperature and perihematomal edema volume in acute spontaneous ICH. © 2014 World Stroke Organization.

    Randomised trials have shown that alteplase improves the odds of a good outcome when delivered within 4·5 h of acute ischaemic stroke. However, alteplase also increases the risk of intracerebral haemorrhage; we aimed to determine the proportional and absolute effects of alteplase on the risks of intracerebral haemorrhage, mortality, and functional impairment in different types of patients. We used individual patient data from the Stroke Thrombolysis Trialists' (STT) meta-analysis of randomised trials of alteplase versus placebo (or untreated control) in patients with acute ischaemic stroke. We prespecified assessment of three classifications of intracerebral haemorrhage: type 2 parenchymal haemorrhage within 7 days; Safe Implementation of Thrombolysis in Stroke Monitoring Study's (SITS-MOST) haemorrhage within 24-36 h (type 2 parenchymal haemorrhage with a deterioration of at least 4 points on National Institutes of Health Stroke Scale [NIHSS]); and fatal intracerebral haemorrhage within 7 days. We used logistic regression, stratified by trial, to model the log odds of intracerebral haemorrhage on allocation to alteplase, treatment delay, age, and stroke severity. We did exploratory analyses to assess mortality after intracerebral haemorrhage and examine the absolute risks of intracerebral haemorrhage in the context of functional outcome at 90-180 days. Data were available from 6756 participants in the nine trials of intravenous alteplase versus control. Alteplase increased the odds of type 2 parenchymal haemorrhage (occurring in 231 [6·8%] of 3391 patients allocated alteplase vs 44 [1·3%] of 3365 patients allocated control; odds ratio [OR] 5·55 [95% CI 4·01-7·70]; absolute excess 5·5% [4·6-6·4]); of SITS-MOST haemorrhage (124 [3·7%] of 3391 vs 19 [0·6%] of 3365; OR 6·67 [4·11-10·84]; absolute excess 3·1% [2·4-3·8]); and of fatal intracerebral haemorrhage (91 [2·7%] of 3391 vs 13 [0·4%] of 3365; OR 7·14 [3·98-12·79]; absolute excess 2·3% [1

    Proximal or 'downhill' esophageal varices are a rare cause of upper gastrointestinal hemorrhage. Unlike the much more common distal esophageal varices, which are most commonly a result of portal hypertension, downhill esophageal varices result from vascular obstruction of the superior vena cava (SVC). While SVC obstruction is most commonly secondary to malignant causes, our review of the literature suggests that benign causes of SVC obstruction are the most common cause actual bleeding from downhill varices. Given the alternative pathophysiology of downhill varices, they require a unique approach to management. Variceal band ligation may be used to temporize acute variceal bleeding, and should be applied on the proximal end of the varix. Relief of the underlying SVC obstruction is the cornerstone of definitive treatment of downhill varices. A young woman with a benign superior vena cava stenosis due to a tunneled internal jugular vein dialysis catheter presented with hematemesis and melena. Urgent upper endoscopy revealed multiple 'downhill' esophageal varices with stigmata of recent hemorrhage. As there was no active bleeding, no endoscopic intervention was performed. CT angiography demonstrated stenosis of the SVC surrounding the distal tip of her indwelling hemodialysis catheter. The patient underwent balloon angioplasty of the stenotic SVC segment with resolution of her bleeding and clinical stabilization. Downhill esophageal varices are a distinct entity from the more common distal esophageal varices. Endoscopic therapies have a role in temporizing active variceal bleeding, but relief of the underlying SVC obstruction is the cornerstone of treatment and should be pursued as rapidly as possible. It is unknown why benign, as opposed to malignant, causes of SVC obstruction result in bleeding from downhill varices at such a high rate, despite being a less common etiology of SVC obstruction.

    In the setting of portal hypertension, the body responds by creating portosystemic venous shunts, which may lead to the development of varices. Endoscopic treatment of these varices is often warranted to prevent catastrophic bleeding. During the course of variceal treatment, 1 or more portosystemic shunts may be sacrificed, which may acutely exacerbate portal hypertension and reduce systemic venous return. This report describes percutaneous creation of a mesocaval shunt and balloon-occluded retrograde transvenous obliteration (BRTO) in a patient with cavernous transformation of the portal vein. The patient had previously undergone an unsuccessful attempt at transjugular intrahepatic portosystemic shunt (TIPS) creation with postoperative bleeding requiring splenectomy. As TIPS was not feasible, creation of a percutaneous mesocaval shunt provided an alternate pathway for portosystemic decompression, facilitating safe treatment of gastric varices with BRTO via a gastrorenal shunt. These procedures were performed simultaneously to reduce the risk of variceal bleeding from acute changes in portal venous pressures and redirect blood flow through the shunt to maintain patency. This is the first reported case of combined mesocaval shunt placement and BRTO in a single session. Copyright © 2017 Elsevier Inc. All rights reserved.

    To find the most accurate, suitable, and applicable scoring system for the prediction of outcome in cirrhotic patients with bleeding varices. A prospective study was conducted comprising 120 cirrhotic patients with acute variceal bleeding who were admitted to Tropical Medicine and Gastroenterology Department in Sohag University Hospital, over a 1-year period (1/2015 to 1/2016). The clinical, laboratory, and endoscopic parameters were studied. Child-Turcotte-Pugh (CTP) classification score, Model for end-stage liver disease (MELD) score, acute physiology and chronic health evaluation II (APACHE II) score, sequential organ failure assessment (SOFA) score, and AIMS65 score were calculated for all patients. Univariate and multivariate analyses were performed for all the measured parameters and scores. Of the 120 patients (92 male) admitted during the study period, eight patients (6.67%) died in the hospital. Advanced age, the presence of encephalopathy, rebleeding, and higher serum bilirubin were independent factors associated with higher hospital mortality. The largest area under the receiver operator curve (AUROC) was obtained for the AIMS65 score and SOFA score, followed by the MELD score and APACHEII score, then CTP score, all of which achieved very good performance (AUROC>0.8). AIMS65 score showed the best sensitivity, specificity, and negative and positive predictive values. Although the AIMS65 score was not significantly different from the MELD, SOFA, and APACHEII scores, it was the optimum among them in terms of the prediction of mortality. AIMS65 score is the best simple and applicable scoring system for independently predicting mortality in cirrhotic patients with acute variceal bleeding.

    Intracerebral haemorrhage accounts for 10%-15% of all strokes; however it has a poor prognosis with higher rates of morbidity and mortality. Neurological deterioration is often observed during the first hours after onset and determines poor prognosis. Intracerebral haemorrhage, therefore, is a neurological emergency which must be diagnosed and treated properly as soon as possible. In this guide we review the diagnostic procedures and factors that influence the prognosis of patients with intracerebral haemorrhage and we establish recommendations for the therapeutic strategy, systematic diagnosis, acute treatment and secondary prevention for this condition.

    A 43-year-old male with alcoholic cirrhosis underwent EGD for hematemesis which revealed bleeding, grade II, lower esophageal varices that were endoscopically ligated with 6 bands. All the bands remained attached to varices at the completion of EGD. Despite apparent initial hemostasis, balloon tamponade was performed one hour later for suspected continued bleeding. Due to suspected continuing bleeding, EGD was repeated 4 h after initial EGD, and 3 h after balloon tamponade. This EGD revealed the esophageal varices; none of the bands remaining on esophageal mucosa; multiple mucosal stigmata likely from trauma at initial site of variceal bands before dislodgement; and 3 dislodged bands in gastric body, duodenal bulb, or descending duodenum. The patient expired 17 h thereafter from hypovolemic shock. This single report may suggest an apparently novel, balloon tamponade complication: dislodgement of previously placed, endoscopic bands. The proposed pathophysiology is release of bands by stretching entrapped, esophageal mucosa during esophageal balloon tamponade. This complication, if confirmed, might render balloon tamponade a less desirable option very soon after band ligation.

    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 bleeding within a colloid cyst of the third ventricle represents a rare event causing sudden increase in the cyst volume that may lead to acute hydrocephalus and rapid neurological deterioration. We report a case of spontaneous rupture of haemorrhagic third ventricular colloid cyst and its management. A 77-year-old ex-smoker presented with unsteady gait, incontinence and gradually worsening confusion over a 3-week period. Brain CT scan findings were highly suggestive of a third ventricular colloid cyst with intraventricular rupture. He underwent cyst excision and histopathology, which confirmed the radiological diagnosis with evidence of haemorrhage within the cyst. A ventriculo peritoneal shunt was performed for delayed hydrocephalus. Surgical management of these patients must include emergency ventriculostomy followed by prompt surgical removal of the haemorrhagic cyst. PMID:22949002

    Spontaneous pure acute bilateral subdural haematoma (ASDH) without intraparenchymal or subarachnoid haemorrhage caused by a ruptured cerebral aneurysm is extremely rare. It can follow rupture of different aneurysms specially located in anterior incisural space; the most frequently encountered location is the PcoA aneurysms as demonstrated in the present case. We present a case report of a PcoA aneurysm presenting as pure bilateral ASDH. A high level of suspicion for bleeding of arterial origin should be maintained in all cases of acute subdural haematoma without history of trauma. The neurological status on admission dictates the appropriate timing and methodology of the neuroradiological investigations. PMID:25045554

    The authors describe a case of L-asparaginase induced intracranial thrombosis and subsequent haemorrhage in a newly diagnosed 30-year-old man with acute lymphoblastic leukaemia who was successfully managed by surgical intervention. At presentation, he had a Glasgow Coma Score of 7/15, was aphasic and had dense right hemiplegia. Neuroimaging revealed an acute anterior left middle cerebral artery infarct with parenchymal haemorrhagic conversion, mass effect and subfalcine herniation. He subsequently underwent left frontal craniotomy and evacuation of large frontal haematoma and decompressive craniectomy for cerebral oedema. Six months postoperatively he underwent titanium cranioplasty. He had made good clinical recovery and is currently mobilising independently with mild occasional episodes of expressive dysphasia, difficulty with fine motor movement on the right side, and has remained seizure free. This is the first documented case of L-asparaginase induced haemorrhagic stroke managed by neurosurgical intervention. The authors emphasise the possible role of surgery in managing chemotherapy induced intracranial complications. PMID:22605598

This generally benign phenomenon is an identifiable complication of supratentorial craniotomies and should not be mistaken with other pathologies. The most common presenting symptom is a decrease in the level of consciousness but in some cases the RCH may be asymptomatic and accidentally discovered in follow-up CT scans. A 70-year-old man was admitted to our emergency department with sudden mental status deterioration. A head CT scan was carried out and an acute hydrocephalus was diagnosed. The patient was transferred to the operating room for external ventricular drainage (EVD) placement via a frontal burr-hole. At 24hours, the patient made a complete neurological recovery. On third postoperative day, a follow-up CT scan showed an asymptomatic right remote cerebellar haemorrhage. The MRI assessment confirmed the diagnosis. The EVD was removed on the 6th postoperative day and the patient was discharged after one week with no further symptoms. This case report is the first documented case, to our knowledge, of a remote cerebellar haemorrhage after placement of external ventricular drainage via a frontal burr-hole. The precise aetiology of remote cerebellar haemorrhage remains unclear. One of the most accepted theories is the "cerebellar sag" explanation, which defends hypothesis that peri-operative over drainage of cerebrospinal fluid (CSF) is the main mechanism involved. Further investigation is required to understand the pathogenesis and risk factors for the occurrence of this phenomenon. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

    Spontaneous intracerebral haemorrhage is a devastating form of stroke and its incidence increases with age. Obtaining brain tissue following intracerebral haemorrhage helps to understand its cause. Given declining autopsy rates worldwide, the feasibility of establishing an autopsy-based collection and its generalisability are uncertain. We used multiple overlapping sources of case ascertainment to identify every adult diagnosed with intracerebral haemorrhage between 1st June 2010-31st May 2012, whilst resident in the Lothian region of Scotland. We sought consent from patients with intracerebral haemorrhage (or their nearest relative if the patient lacked mental capacity) to conduct a research autopsy. Of 295 adults with acute intracerebral haemorrhage, 110 (37%) could not be approached to consider donation. Of 185 adults/relatives approached, 91 (49%) consented to research autopsy. There were no differences in baseline demographic variables or markers of intracerebral haemorrhage severity between consenters and non-consenters. Adults who died and became donors (n = 46) differed from the rest of the cohort (n = 249) by being older (median age 80, IQR 76-86 vs. 75, IQR 65-83, p = 0.002) and having larger haemorrhages (median volume 23 ml, IQR 13-50 vs. 13 ml, IQR 4-40; p = 0.002). Nearly half of those approached consent to brain tissue donation after acute intracerebral haemorrhage. The characteristics of adults who gave consent were comparable to those in an entire community, although those who donate early are older and have larger haemorrhage volumes.

    In the past 20 years, our understanding of the pathophysiology and management options among patients with gastric varices (GV) has changed significantly. GV are the most common cause of upper gastrointestinal bleeding in patients with portal hypertension after esophageal varices (EV) and generally have more severe bleeding than EV. In the United States, the majority of GV patients have underlying portal hypertension rather than splenic vein thrombosis. The widely used classifications are the Sarin Endoscopic Classification and the Japanese Vascular Classifications. The former is based on the endoscopic appearance and location of the varices, while the Japanese classification is based on the underlying vascular anatomy. In this article, the authors address the current concepts of classification, epidemiology, pathophysiology, and emerging management options of gastric varices. They describe the stepwise approach to patients with gastric varices, including the different available modalities, and the pearls, pitfalls, and stop-gap measures useful in managing patients with gastric variceal bleed.

    Postpartum haemorrhage is a major cause of maternal mortality in the developing world. Although effective methods for prevention and treatment of such haemorrhage exist--such as the uterotonic drug oxytocin--most are not feasible in resource-poor settings where many births occur at home. We aimed to investigate whether oral misoprostol, a potential alternative to oxytocin, could prevent postpartum haemorrhage in a community home-birth setting. In a placebo-controlled trial undertaken between September, 2002, and December, 2005, 1620 women in rural India were randomised to receive oral misoprostol (n=812) or placebo (n=808) after delivery. 25 auxiliary nurse midwives undertook the deliveries, administered the study drug, and measured blood loss. The primary outcome was the incidence of acute postpartum haemorrhage (defined as > or =500 mL bleeding) within 2 h of delivery. Analysis was by intention-to-treat. The trial was registered with the US clinical trials database (http://www. clinicaltrials.gov) as number NCT00097123. Oral misoprostol was associated with a significant reduction in the rate of acute postpartum haemorrhage (12.0% to 6.4%, p<0.0001; relative risk 0.53 [95% CI 0.39-0.74]) and acute severe postpartum haemorrhage (1.2% to 0.2%, p<0.0001; 0.20 [0.04-0.91]. One case of postpartum haemorrhage was prevented for every 18 women treated. Misoprostol was also associated with a decrease in mean postpartum blood loss (262.3 mL to 214.3 mL, p<0.0001). Postpartum haemorrhage rates fell over time in both groups but remained significantly higher in the placebo group. Women taking misoprostol had a higher rate of transitory symptoms of chills and fever than the control. Oral misoprostol was associated with significant decreases in the rate of acute postpartum haemorrhage and mean blood loss. The drug's low cost, ease of administration, stability, and a positive safety profile make it a good option in resource-poor settings.

    Patients suffering from intracerebral haemorrhage have a poor prognosis, especially if they are using antiplatelet therapy. Currently, no effective acute treatment option for intracerebral haemorrhage exists. Limiting the early growth of intracerebral haemorrhage volume which continues the first hours after admission seems a promising strategy. Because intracerebral haemorrhage patients who are on antiplatelet therapy have been shown to be particularly at risk of early haematoma growth, platelet transfusion may have a beneficial effect. The primary objective is to investigate whether platelet transfusion improves outcome in intracerebral haemorrhage patients who are on antiplatelet treatment. The PATCH study is a prospective, randomised, multi-centre study with open treatment and blind endpoint evaluation. Patients will be randomised to receive platelet transfusion within six hours or standard care. The primary endpoint is functional health after three months. The main secondary endpoints are safety of platelet transfusion and the occurrence of haematoma growth. To detect an absolute poor outcome reduction of 20%, a total of 190 patients will be included. To our knowledge this is the first randomised controlled trial of platelet transfusion for an acute haemorrhagic disease.

    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

    Band ligation and propranolol are the current therapies for primary prevention of variceal bleeding. Carvedilol is a rising nonselective beta-blocker used for reducing portal pressure with favorable outcome. The aim of this study to assess the efficacy of carvedilol, propranolol, and band ligation for primary prevention of variceal bleeding based on the effect of each regimen on progression of Child score and portal hypertensive gastropathy after 1 year. The study included 264 cirrhotic patients with medium/large-sized varices who were candidates for primary prophylaxis of variceal bleeding. Patients were randomly divided into three groups: group I: band ligation; group II: propranolol; group III: carvedilol. Group I showed higher success rate of 75 %, followed by group III with 70.2 % and group II with 65.2 %. Risk of bleeding was comparable between the three groups, with group II carrying the highest rate of complications (34.7 %) followed by group III (14.2 %) and finally group I (5.7 %). After 1 year of follow-up, Child score did not improve in any of the studied groups, while portal hypertensive gastropathy significantly increased in group I but decreased in groups II and III. Band ligation is the best treatment option for primary prevention of variceal bleeding with minimal complications. Carvedilol is a good pharmaceutical alternative medicine to propranolol with lesser side-effects. Progress of liver disease as represented by Child score is not affected by any of the primary variceal prophylactic regimens, although medical treatment reduces portal hypertensive gastropathy. Choice of treatment depends on patient will, compliance with treatment, and endoscopist competence.

    Gastric varices can occur in as many as one-third of patients with portal hypertension. Within the nursing literature, however, articles focus on the management of esophageal varices and portal hypertensive gastrointestinal bleeding with few publications about management of gastric varices. Given the advancement in therapies, it is prudent for gastroenterology nurses to have an understanding of its management and treatment options. This article reviews the pathophysiology, classification, and management of patients with gastric varices and outlines the importance of the nurse's role in the education and ongoing care for this patient group.

    Assessing the likelihood of a variceal versus nonvariceal source of upper gastrointestinal bleeding (UGIB) guides therapy, but can be difficult to determine on clinical grounds. The objective of this study was to determine if there are easily ascertainable clinical and laboratory findings that can identify a patient as low risk for a variceal source of hemorrhage. This was a retrospective cohort study of adult ED patients with UGIB between January 2008 and December 2014 who had upper endoscopy performed during hospitalization. Clinical and laboratory data were abstracted from the medical record. The source of the UGIB was defined as variceal or nonvariceal based on endoscopic reports. Binary recursive partitioning was utilized to create a clinical decision rule. The rule was internally validated and test characteristics were calculated with 1,000 bootstrap replications. A total of 719 patients were identified; mean age was 55 years and 61% were male. There were 71 (10%) patients with a variceal UGIB identified on endoscopy. Binary recursive partitioning yielded a two-step decision rule (platelet count > 200 × 10 9 /L and an international normalized ratio [INR] < 1.3), which identified patients who were low risk for a variceal source of hemorrhage. For the bootstrapped samples, the rule performed with 97% sensitivity (95% confidence interval [CI] = 91%-100%) and 49% specificity (95% CI = 44%-53%). Although this derivation study must be externally validated before widespread use, patients presenting to the ED with an acute UGIB with platelet count of >200 × 10 9 /L and an INR of <1.3 may be at very low risk for a variceal source of their upper gastrointestinal hemorrhage. © 2017 by the Society for Academic Emergency Medicine.

    Hematuria from a neobladder can occur due to a variety of pathologies including tumors, stones, and fistulas. Variceal bleeding in a neobladder is a very rare condition with only one case reported in literature. We present a case of a patient with cirrhosis and portal hypertension and an ileocolic orthotopic neobladder presenting with hematuria. Computed tomographic angiography showed dilated varices around the neobladder which were successfully embolized. To the best of our knowledge, this is the first report case of variceal bleeding in a neobladder successfully managed with the combination of TIPS (transjugular intrahepatic portosystemic shunt) procedure and embolization.

    Recent guidelines recommend that all cirrhotics undergo screening upper endoscopy to identify those patients at risk for bleeding from varices. However, this practice may not be cost effective as large esophageal varices are seen only in 9-36% of these patients. The aim of this study was to determine whether clinical variables were predictive of the presence of large esophageal varices. This is a retrospective analysis of cirrhotics who had a screening upper endoscopy during an evaluation for liver transplantation at three different centers and who had not previously bled from varices. A multivariate model was derived on the combined cohort using logistic regression. Three hundred forty-six patients were eligible for the study. The prevalence of large esophageal varices was 20%. On multivariate analysis, splenomegaly detected by computed tomographic scan (odds ratio: 4.3; 95% confidence interval: 1.6-11.5) or by physical examination (odds ratio: 2.0; 95% confidence interval: 1.1-3.8), and low platelet count were independent predictors of large esophageal varices. On the basis of these variables, cirrhotics were stratified into high- and low-risk groups for the presence of large esophageal varices. Patients with a platelet count of > or = 88,000/mm3 (median value) and no splenomegaly by physical examination had a risk of large esophageal varices of 7.2%. Those with splenomegaly or platelet count < 88,000/mm3 had a risk of large esophageal varices of 28% (p < 0.0001). Our data show that clinical predictors could be used to stratify cirrhotic patients for the risk of large esophageal varices and such stratification could be used to improve the cost effectiveness of screening endoscopy.

    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

    Late seizures after intracerebral haemorrhage occur after the initial acute haemorrhagic insult subsides, and represent one of its most feared long-term sequelae. Both susceptibility to late seizures and their functional impact remain poorly characterized. We sought to: (i) compare patients with new-onset late seizures (i.e. delayed seizures), with those who experienced a recurrent late seizure following an immediately post-haemorrhagic seizure; and (ii) investigate the effect of late seizures on long-term functional performance after intracerebral haemorrhage. We performed prospective longitudinal follow-up of consecutive intracerebral haemorrhage survivors presenting to a single tertiary care centre. We tested for association with seizures the following neuroimaging and genetic markers of cerebral small vessel disease: APOE variants ε2/ε4, computer tomography-defined white matter disease, magnetic resonance imaging-defined white matter hyperintensities volume and cerebral microbleeds. Cognitive performance was measured using the Modified Telephone Interview for Cognitive Status, and functional performance using structured questionnaires obtained every 6 months. We performed time-to-event analysis using separate Cox models for risk to develop delayed and recurrent seizures, as well as for functional decline risk (mortality, incident dementia, and loss of functional independence) after intracerebral haemorrhage. A total of 872 survivors of intracerebral haemorrhage were enrolled and followed for a median of 3.9 years. Early seizure developed in 86 patients, 42 of whom went on to experience recurrent seizures. Admission Glasgow Coma Scale, increasing haematoma volume and cortical involvement were associated with recurrent seizure risk (all P < 0.01). Recurrent seizures were not associated with long-term functional outcome (P = 0.67). Delayed seizures occurred in 37 patients, corresponding to an estimated incidence of 0.8% per year (95% confidence interval 0.5–1

    Haemorrhagic cystitis is an uncommon and, in its severe form, potentially life-threatening complication of haematopoietic stem cell transplantation or cancer therapy in children. The severe form involves macroscopic haematuria with blood clots, urinary obstruction and/or renal impairment. There are many therapeutic options to treat acute haemorrhage, but only recombinant factor VII has a high level of clinical evidence in children. Supraselective vesical artery embolization (SVAE) is an increasingly used therapeutic procedure for controlling haemorrhage in adults, but is less commonly used in children. This might be due to several factors, such as the invasive nature of the procedure, lack ofmore » appropriate medical experience and possible long-term side effects.

    To evaluate the feasibility, safety, and clinical outcomes of plug-assisted retrograde transvenous obliteration (PARTO) to treat gastric variceal hemorrhage in patients with portal hypertension. From May 2012 to June 2014, 19 patients (11 men and 8 women, median age; 61, with history of gastric variceal hemorrhage; 17, active bleeding; 2) who underwent PARTO using a vascular plug and a gelfoam pledget were retrospectively analyzed. Clinical and laboratory data were examined to evaluate primary (technical and clinical success, complications) and secondary (worsening of esophageal varix [EV], change in liver function) end points. Median follow-up duration was 11 months, from 6.5 to 18 months. The Wilcoxon signed-rank test was used to compare laboratory data before and after the procedure. Technical success (complete occlusion of the efferent shunt and complete filling of gastric varix [GV] with a gelfoam slurry) was achieved in 18 of 19 (94.7%) patients. The embolic materials could not reach the GV in 1 patient who had endoscopic glue injection before our procedure. The clinical success rate (no recurrence of gastric variceal bleeding) was the same because the technically failed patient showed recurrent bleeding later. Acute complications included fever (n = 2), fever and hypotension (n = 2; one diagnosed adrenal insufficiency), and transient microscopic hematuria (n = 3). Ten patients underwent follow-up endoscopy; all exhibited GV improvement, except 2 without endoscopic change. Five patients exhibited aggravated EV, and 2 of them had a bleeding event. Laboratory findings were significantly improved after PARTO. PARTO is technically feasible, safe, and effective for gastric variceal hemorrhage in patients with portal hypertension.

    To establish risk of hemorrhage in patients with varices compared to those without, determine additional risk factors, and make evidence-based treatment recommendations. Retrospective cohort study. Patients who were vocal performers presenting for care during a 24-month period were analyzed to determine incidence of hemorrhage. Patients with varices were compared to those without. Demographic information and examination findings (presence, location, character, and size of varices; presence of mucosal lesions or paresis) were analyzed to determine predictors of hemorrhage. A total of 513 patients (60.4% female, mean age 36.6 years ± 13.95 years) were evaluated; 14 patients presenting with hemorrhage were excluded. One hundred and twelve (22.4%) patients had varices; 387 (77.6%) did not. The rate of hemorrhage in patients with varices was 2.68% at 12 months compared to 0.8% in patients without. Cox proportional hazard regression analysis revealed a hazard ratio of 10.1 for patients with varix developing hemorrhage compared to nonvarix patients (P < 0.0001). The incidence rate of hemorrhage was 3.3 cases per 1,000 person-months for varix patients compared to 0.5 cases per 1,000 person-months in the nonvarix group. There was no significant difference in the incidence of paresis, mucosal lesions, location of varix (left or right side; medial or lateral), or varix morphology (pinpoint, linear, lake) between patients who hemorrhaged and those that did not. The presence of varices increases the risk of hemorrhage. Varix patients had 10 times the rate of hemorrhage compared to nonvarix patients, although the overall incidence is low. This data may be used to inform treatment of patients with varices. 4. Laryngoscope, 126:1163-1168, 2016. © 2015 The American Laryngological, Rhinological and Otological Society, Inc.

    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.

    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.

    Thrombophilia in adults is one of main causes of portal vein thrombosis. Esophageal and gastric varices, ascites and hypersplenism are well known complications of portal hypertension. There are controversial issues on the management, especially anticoagulant therapy and surgical treatment of these patients. We present a 42-years old woman with a history of three acute coronary episodes suffering from recurrent variceal bleeding due to portal and splenic vein thrombosis in the course of myeloproliferative disorder and protein C deficiency. It was 10 months delay of diagnosis. She was successfully treated with medical and surgical treatment (esophageal stapler transection, cardial devascularization, and splenectomy). In the paper we discuss complexity of diagnosis and surgical treatment.

    To find out the recurrence of esophageal varices, evolution of gastric varices, portal hypertensive gastropathy (PHG) and risk of rebleeding following esophageal variceal eradication. Between 1992 and 2002, children with extrahepatic portal venous obstruction (EHPVO) and bleeding from esophageal varices received endoscopic injection sclerotherapy until eradication. Surveillance endoscopy was performed initially at 3 months and subsequently at intervals of 6 months to one year to detect esophageal and gastric varices, and PHG. Gastric varices were classified as gastroesophageal (GOV) or isolated gastric varices (IGV). Gastroesophageal varices included types GOV1 and GOV2 that extend along lesser and greater curvatures respectively. Patients who had recurrence of bleeding were evaluated by emergency upper gastrointestinal endoscopy. 163 of 183 children who achieved esophageal variceal eradication were evaluated. Esophageal varices recurred in 40% cases. Primary gastric varices (before sclerotherapy) were seen in 61% cases [GOV 98% (83% GOV1, 15% GOV2) and IGV 2%] and secondary (after sclerotherapy) in 28% [GOV 71% (47% GOV1, 24% GOV2) and IGV 29%]. Secondary gastric varices were distributed as 20% GOV1, 42% GOV2 and 87% IGV. Frequency of gastric varices before sclerotherapy and at the last follow up showed decrease in GOV1 from 82 to 56 (P = 0.02), increase in GOV2 from 15 to 23 and increase in IGV from 2 to 15 (P < 0.001). PHG increased in frequency from 12% to 41% (P < 0.001) and severity from one patient to 12 (P < 0.001). Eleven cases had rebleeding from gastric varices (5 GOV1, 4 GOV2 and 2 IGV). Following esophageal variceal eradication in children with EHPVO a significant decrease in GOV1, increase in IGV and increased frequency and severity of PHG takes place. Small rebleeding risk persists from gastric varices irrespective of the type.

    Optimal endoscopic treatment of gastric varices is still not standardized nowadays. Actively bleeding varices may prohibit a successful endoscopic injection therapy of Histoacryl® (N-butyl-2-cyanoacrylate). Since 2006, we have treated gastric varices by standardized endoscopic ultrasound (EUS) guided Histoacryl injection therapy without severe adverse events. We present a large single-center cohort over 7 years with a standardized EUS-guided sclerotherapy of all patients with gastric varices. Application was controlled by fluoroscopy to immediately detect any glue embolization. Only perforating veins located within the gastric wall were treated. In the follow up, we repeated this treatment until varices were eradicated. Utmost patients (36 of 40) were treated during or within 24 h of active bleeding. About 32.5% of patients were treated while visible bleeding. Histoacryl injection was always technically successful and only two patients suffered a minor complication. Acute bleeding was stopped in all patients. About 15% (6 of 40) of patients needed an alternative rescue treatment in the longer course. Three patients got a transjugular portosystemic shunt and another three underwent an orthotopic liver transplantation. Mean long-term survival of 60 months was excellent. Active bleeding of gastric varices can be treated successfully without the necessity of gastric rinsing with EUS-guided injection of Histoacryl.

    To study the diagnosis and treatment of varices of the vocal cord. The clinical data of 21 cases with varix of vocal cord were analyzed. All the patients presented hoarseness. There were 15 female and 6 male cases with their ages ranged from 23 to 68 years (median 44 years old). The varix was found on the right vocal cord in 12 cases, on the left vocal cord in 9 cases. Isolated varix existed on the vocal cord in 10 cases, varix with vocal cord polyps or nodules in 10 cases, varix with vocal cord paralysis in 1 case. All the patients were diagnosed under the laryngovideoscopy. The lesions appeared on the superior surface of the vocal cord. Varices manifested as abnormally dilated capillary running in the anterior to posterior direction in 6 cases, as clusters of capillary in 3 cases, as a dot or small sheet or short line of capillary in 12 cases. The varices were disappeared in 2 of 8 cases with vocal cord varices and polyps after removed the polyps. The varices of others patients had no change after following up for more than 6 months, but one patient happened hemorrhage of the contralateral vocal cord. Varices are most commonly seen in female. Laryngovideoscopy is the key in determining the vocal fold varices. Management of patients with a varix includes medical therapy, speech therapy, and occasionally surgical vaporization.

  2. Acute tracheal oedema and haemorrhage with fibrinonecrotic tracheitis in pigs--a porcine counterpart of bovine honker syndrome?

    Cases of acute tracheal oedema and haemorrhage with fibrinonecrotic tracheitis have been described in Hungarian pig herds. Clinical signs and gross and microscopical tracheal lesions bore resemblance to those of bovine 'honker syndrome'. Diagnostic examination of affected tracheas and corresponding lungs revealed the presence of a variety of agents; however, in some cases tracheal lesions developed without detectable pathogens or associated pulmonary pathology. In line with the bovine condition, this suggests the possibility of cough-induced tracheal damage as an initiating factor for this tracheal change in swine. Copyright © 2014 Elsevier Ltd.

    The objective of the study is to investigate the anti-snake venom activities of a local plant, Hibiscus aethiopicus L. The H. aethiopicus was dried and extracted with ethanol. Different assays were performed according to standard techniques, to evaluate the plant's acute toxicity and its antivenom activities. The results of evaluating the systemic acute toxicity of the H. aethiopicus extract using "oral and intra-peritoneal" route were normal even at the highest dose (24 g/kg) tested. All guinea pigs (n = 3) when treated with venoms E. c. sochureki (75 μg) alone induced acute skin haemorrhage. In contrast, all guinea pigs (n = 18) treated with both venom and the plant extract at a concentration between 500 and 1000 mg/kg showed no signs of haemorrhage. Moreover, all guinea pigs (n = 18) treated with venom and the plant extract below 400 mg/kg showed acute skin haemorrhage. All guinea pigs treated with venom E. c. sochureki (75 μg) alone induced acute skin haemorrhage after both 24 and 32 hours. In contrast, all guinea pigs treated with both venom and the plant extract (administered independently) at concentrations between 500 and 1000 mg/kg showed no signs of haemorrhage after 32 hours. However, after 24 hours all tested guinea pigs showed less inhibition (<60%) compared to that obtained after 32 hours. The outcome of this study reflects that the extract of H. aethiopicus plant may contain an endogenous inhibitor of venom induced local haemorrhage.

    The new methods of cannabis consumption (home made water pipe or "bang") may be responsible for fatal respiratory complications. We present a case, with fatal outcome, of a man of 19 years with no previous history other than an addiction to cannabis using "bang". He was admitted to intensive care with acute dyspnoea. A CT scan showed bilateral, diffuse alveolar shadowing. He was anaemic with an Hb of 9.3g/l. Bronchoalveolar lavage revealed massive alveolar haemorrhage. Investigations for infection and immunological disorder were negative and toxicology was negative except for cannabis. Antibiotic treatment was given and favourable progress allowed early discharge. Death occurred 15 days later due to alveolar haemorrhage following a further "bang" of cannabis. Autopsy showed toxic alveolar haemorrhage. The probable mechanism is pulmonary damage due to acid anhydrides released by the incomplete combustion of cannabis in contact with plastic. These acids have a double effect on the lungs: a direct toxicity with severe inflammation of the mucosa leading to alveolar haemorrhage and subsequently the acid anhydrides may lead to the syndrome of intra-alveolar haemorrhage and anaemia described in occupational lung diseases by Herbert in Oxford in 1979. It manifests itself by haemoptysis and intravascular haemolysis. We draw attention to the extremely serious potential consequences of new methods of using cannabis, particularly the use of "bang" in homemade plastic materials. Copyright © 2011 SPLF.

    Cirrhosis of the liver is a common complication of chronic liver disease and is associated with portal hypertension and esophageal varices. In this study, we checked the implication of prothrombin time, if any, in the genesis of esophageal varices. Sixty patients with cirrhosis of the liver were randomly assigned into two groups: Group I - 30 cirrhotic patients with esophageal varices, and group II - 30 cirrhotic patients without esophageal varices. The prothrombin time was checked for both groups. A positive correlation was found between the prolonged plasma prothrombin time (> 4 seconds) and esophageal varices with a sensitivity of 56.67% and specificity of 73.33%. The Child-Pugh score showed a correlation; however, the size of varices did not exhibit any such relation. Prothrombin time may be cautiously used to assess portal hypertension in a field level and rural setting where endoscopy is not available or feasible.

    The term, portal biliopathy, denotes various biliary abnormalities, such as stenosis and/or dilatation of the bile duct, in patients with portal hypertension. These vascular abnormalities sometimes bring on an obstructive jaundice, but they are not clear which vessels participated in obstructive jaundice. The aim of present study was clear the bile ductal changes in patients with portal hypertension in hopes of establishing a therapeutic strategy for obstructive jaundice caused by biliary varices. Three hundred and thirty-seven patients who underwent intraductal ultrasound (IDUS) during endoscopic retrograde cholangiography for biliary abnormalities were enrolled. Portal biliopathy was analyzed using IDUS. Biliary varices were identified in 11 (2.7%) patients. IDUS revealed biliary varices as multiple, hypoechoic features surrounding the bile duct wall. These varices could be categorized into one of two groups according to their location in the sectional image of bile duct: epicholedochal and paracholedochal. Epicholedochal varices were identified in all patients, but paracholedochal varices were observed only in patients with extrahepatic portal obstruction. IDUS was useful to characterize the anatomy of portal biliopathy in detail.

    In 2017, numerous cases of acute haemorrhagic conjunctivitis (AHC) were reported in the Caribbean and in South America. Preliminary reports identified adenoviruses and enteroviruses in some patient samples but, until now, none of the etiologic agents have been fully characterized. We report the full-length genomic sequences of 4 coxsackievirus A24 (CV-A24) isolates collected from AHC patients in French Guiana during this outbreak (May and June 2017). These isolates are very closely related and belong to the genotype IV of CV-A24 variant, which consists of strains sampled worldwide during AHC outbreaks in the 2000s and 2010s. No recombination events were detected within the genomic sequences, indicating that members of this genotype have continuously circulated worldwide for more than 10 years without undergoing recombination with other enteroviruses. This unusual trait could be due to their ocular tropism that could impede genetic exchanges between these viruses and other enteroviruses, which replicate mainly in the gut. © 2018 S.

    2016-01-01

    AIM: To determine the feasibility and safety of transgastric direct endoscopic necrosectomy (DEN) in patients with walled-off necrosis (WON) and gastric varices. METHODS: A single center retrospective study of consecutive DEN for WON was performed from 2012 to 2015. All DEN cases with gastric fundal varices noted on endoscopy, computed tomography (CT) or magnetic resonance imaging (MRI) during the admission for DEN were collected for analysis. In all cases, external urethral sphincter (EUS) with doppler was used to exclude the presence of intervening gastric varices or other vascular structures prior to 19 gauge fine-needle aspiration (FNA) needle access into the cavity. The tract was serially dilated to 20 mm and was entered with an endoscope for DEN. Pigtail stents were placed to facilitate drainage of the cavity. Procedure details were recorded. Comprehensive chart review was performed to evaluate for complications and WON recurrence. RESULTS: Fifteen patients who underwent DEN for WON had gastric varices at the time of their procedure. All patients had an INR < 1.5 and platelets > 50. Of these patients, 11 had splenic vein thrombosis and 2 had portal vein thrombosis. Two patients had isolated gastric varices, type 1 and the remaining 13 had > 5 mm gastric submucosal varices on imaging by CT, MRI or EUS. No procedures were terminated without completing the DEN for any reason. One patient had self-limited intraprocedural bleeding related to balloon dilation of the tract. Two patients experienced delayed bleeding at 2 and 5 d post-op respectively. One required no therapy or intervention and the other received 1 unit transfusion and had an EGD which revealed no active bleeding. Resolution rate of WON was 100% (after up to 2 additional DEN in one patient) and no patients required interventional radiology or surgical interventions. CONCLUSION: In patients with WON and gastric varices, DEN using EUS and doppler guidance may be performed safely. Successful resolution

    A 55-year-old man with hepatitis B virus antigen-positive liver cirrhosis was admitted to our hospital with anal bleeding. Colonoscopy revealed blood retention in the entire colon, but no bleeding lesion was found. Computed tomography images showed that vessels in the ileum were connected to the right testicular vein, and we suspected ileal varices to be the most probable cause of bleeding. We immediately performed double balloon enteroscopy, but failed to find any site of bleeding owing to the difficulty of fiberscope insertion with sever adhesion. Using a balloon catheter during retrograde transvenous venography, we found ileal varices communicating with the right testicular vein (efferent vein) with the superior mesenteric vein branch as the afferent vein of these varices. We performed balloon occluded retrograde transvenous obliteration by way of the efferent vein of the varices and have detected no further bleeding in this patient one year after treatment.

    Introduction : The Antifibrinolytic Trialists Collaboration aims to increase knowledge about the effectiveness and safety of antifibrinolytic treatment by conducting individual patient data (IPD) meta-analyses of randomised trials. This article presents the statistical analysis plan for an IPD meta-analysis of the effects of antifibrinolytics for acute intracranial haemorrhage. Methods : The protocol for the IPD meta-analysis has been registered with PROSPERO (CRD42016052155). We will conduct an individual patient data meta-analysis of randomised controlled trials with 1000 patients or more assessing the effects of antifibrinolytics in acute intracranial haemorrhage. We will assess the effect on two co-primary outcomes: 1) death in hospital at end of trial follow-up, and 2) death in hospital or dependency at end of trial follow-up. The co-primary outcomes will be limited to patients treated within three hours of injury or stroke onset. We will report treatment effects using odds ratios and 95% confidence intervals. We use logistic regression models to examine how the effect of antifibrinolytics vary by time to treatment, severity of intracranial bleeding, and age. We will also examine the effect of antifibrinolytics on secondary outcomes including death, dependency, vascular occlusive events, seizures, and neurological outcomes. Secondary outcomes will be assessed in all patients irrespective of time of treatment. All analyses will be conducted on an intention-to-treat basis. Conclusions : This IPD meta-analysis will examine important clinical questions about the effects of antifibrinolytic treatment in patients with intracranial haemorrhage that cannot be answered using aggregate data. With IPD we can examine how effects vary by time to treatment, bleeding severity, and age, to gain better understanding of the balance of benefit and harms on which to base recommendations for practice.

    A 55-year-old HIV-infected patient on antiretroviral treatment with Ritonavir-boosted Tipranavir as part of HAART developed intracranial haemorrhage during the acute phase of cryptococcal meningitis. CT scan and MRI confirmed the intracranial haemorrhage. Positive cryptococcal antigen and cultures of both blood and CSF confirmed the diagnosis of meningitis caused by Cryptococcus neoformans. There was no evidence of any bleeding disorder, use of aspirin or antiplatelet agents. The patient was treated with Liposomal Amphotericin B for cryptococcal meningitis. No special treatment was needed for the intracranial haemorrhage, but Tipranavir was discontinued and replaced by Kaletra and Saquinavir. Intracranial haemorrhage could be related to Tipranavir and cryptococcal meningitis was a predisposing factor. Headache stopped 3 days after starting antifungal treatment. To the best of our knowledge, this is the first reported case of intracranial haemorrhage related to Tipranavir treatment after the end of the "RESIST" studies and the only one related to meningitis.

    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.

    Patients with gastric variceal bleeding require a multidisciplinary team approach including hepatologists, endoscopists, diagnostic radiologists, and interventional radiologists. Upper gastrointestinal endoscopy is the first-line diagnostic and management tool for bleeding gastric varices, as it is in all upper gastrointestinal bleeding scenarios. In the United States when endoscopy fails to control gastric variceal bleeding, a transjugular intrahepatic portosystemic shunt (TIPS) traditionally is performed along the classic teachings of decompressing the portal circulation. However, TIPS has not shown the same effectiveness in controlling gastric variceal bleeding that it has with esophageal variceal bleeding. For the past 2 decades, the balloon-occluded retrograde transvenous obliteration (BRTO) procedure has become common practice in Asia for the management of gastric varices. BRTO is gaining popularity in the United States. It has been shown to be effective in controlling gastric variceal bleeding with low rebleed rates. BRTO has many advantages over TIPS in that it is less invasive and can be performed on patients with poor hepatic reserve and those with encephalopathy (and may even improve both). However, its by-product is occlusion of a spontaneous hepatofugal (TIPS equivalent) shunt, and thus it is contradictory to the traditional American doctrine of portal decompression. Indeed, BRTO causes an increase in portal hypertension, with potential aggravation of esophageal varices and ascites. This article discusses the concept, technique, and outcomes of BRTO within the broader management of gastric varices. PMID:23729982

    To evaluate pregnancy outcomes in women with liver cirrhosis, portal hypertension, or esophageal varices. We analyzed a retrospective cohort of 2,284,218 pregnancies in 2005-2009 recorded in the California Birth Registry database. Utilizing ICD-9 codes we analyzed the following outcomes for liver cirrhosis, portal hypertension, or esophageal varices in pregnancy: preeclampsia (PET), preterm delivery (PTD; <37 weeks), cesarean section, low birth weight (LBW; <2500 g), small for gestational age (SGA; <10th percentile), neonatal death (NND), and postpartum hemorrhage (PPH). Cirrhosis in pregnancy conferred an increased risk of PET, PTD, CS in multiparous women, LBW, and NND. Portal hypertension in pregnancy was associated with PTD, LBW, NND, and PPH. Non-bleeding esophageal varices in pregnancy were not associated with the outcomes assessed in a statistically significant manner. One case of bleeding esophageal varices was observed, resulting in PTD with a LBW infant. There were three cases of concomitant portal hypertension or concomitant esophageal varices with cirrhosis in pregnancy. Pregnancy in women with concomitant liver cirrhosis, portal hypertension, or esophageal varices can be successful. However, pregnancy outcomes are worse and may warrant closer antenatal monitoring and patient counseling. Cirrhosis in pregnancy with concomitant portal hypertension or esophageal varices is rare.

    This study aims to evaluate the therapeutic results of percutaneous transhepatic embolization of gastroesophageal varices combined with partial splenic embolization in patients with liver cirrhosis, and to explore the role of this minimally invasive treatment as an alternative to surgery. 25 patients with liver cirrhosis were received percutaneous transhepatic embolization of gastroesophageal varices combined with partial splenic embolization. Another 25 patients with liver cirrhosis underwent Hassab’s operation. They were followed up, and received endoscopy, B ultrasound, liver function and hematologic examination at 24 months after the therapy. In minimal invasive group, before treatment and after 24 month following up after treatment, improved varices, improved portal hypertension and improved hypersplenism were showed comparing with the surgery group, and that they were measured by endoscopic visualization, ultrasound and blood counts. the white blood cell and platelet count were 2.33±0.65 (109/L) and 3.63±1.05 (1010/L), 7.98±3.0 (109/L) and 16.3±9.10 (1010/L) (P<0.05); the diameter of the portal vein were 1.47±0.25 cm, 1.31±0.23 cm (P<0.05). Esophageal varices passed from grade III to lower grade II in 11 patients, and from grade II to lower grade I in 6 patients at 24 month following up. In surgical group, the white blood cell and platelet count were 2.2±0.60 (109/L), 4.1±1.25 (1010/L) before treatment; 9.3±2.56 (109/L), 32.1±12.47 (1010/L) after the treatment at 24 month following up (P<0.05). The diameter of the portal vein were 1.43±0.22 cm before the treatment and 1.28±0.18 cm after the treatment (P<0.05). Esophageal varices passed from grade III to lower grade II in 13 patients, and from grade II to lower grade I in 7 patients. The combination of PGEV and PSE can be considered as an option for the treatment of variceal bleeding with hypersplenism. PMID:26770628

    Purpose Endoscopy is recommended to screen for esophageal varices in patients with cirrhosis. The objective of this study was to identify features on abdominal CT imaging associated variceal hemorrhage (VH). Methods A case–control study was performed among patients with cirrhosis who had a CT scan. Consecutive patients who experienced VH were included as cases, and patients without VH served as controls. Two radiologists recorded the maximal esophageal varix diameter in addition to other measures of portal hypertension at CT. Results The most powerful CT parameter associated with VH was the esophageal varix diameter (5.8 vs. 2.7 mm, p < 0.001; adjusted OR 1.84 per mm, p = 0.009). 63% of individuals with VH had a maximal varix diameter ≥5 mm compared to 7.5% of cirrhotic patients without VH (p < 0.001). In contrast, the proportion of individuals whose largest varix was <3 mm was 7.4% among VH cases compared to 54.7% among controls (p = 0.001). The varix diameter powerfully discriminated those with and without VH (C-statistic 0.84). Conclusions A large esophageal varix diameter is strongly associated with subsequent VH. A threshold of <3 and ≥5 mm appears to identify patients with cirrhosis at low and high risk for hemorrhage. PMID:24366107

    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

    New clinical, endoscopic, and imaging modalities for diagnosing varices and predicting bleeding are being investigated. Transnasal endoscopy and ultrathin battery-powered esophagoscopes are being used to improve patient comfort and compliance. Patients who respond to portal pressure-reducing drugs not only have a reduced risk of bleeding, but also a reduced risk of developing other complications, with improved survival. Nitrates have been shown to have no definite role in primary prophylaxis against variceal bleeding. The hemodynamic response to treatment has an independent prognostic value for the risk of variceal bleeding. Newer drugs have been investigated for reducing the hepatic venous pressure gradient, but with little success. Survival after bleeding has increased due to improved patient care and technological advances. Combined radiographic and endoscopic management of gastric varices is evolving and appears to be promising. Nonvariceal bleeding from portal hypertensive gastropathy is increasingly being recognized as a potential cause of bleeding in patients with portal hypertension, and pharmacotherapy with octreotide appears to be promising for the treatment of this condition. Variceal band ligation in children has been found to be as safe and effective as in adults.

    The outcome of cirrhotic patients with main portal vein occlusion and portal cavernoma after the first episode of acute variceal bleeding (AVB) is unknown. We compared short-term outcomes after AVB in cirrhotic patients with and without portal cavernoma. Between January 2009 and September 2014, 28 patients with cirrhosis and portal cavernoma presenting with the first occurrence of AVB and 56 age-, sex-, and Child-Pugh score-matched cirrhotic patients without portal cavernoma were included. The primary endpoints were 5-day treatment failure and 6-week mortality. The 5-day treatment failure rate was higher in the cavernoma group than in the control group (32.1% versus 12.5%; p = 0.031). The 6-week mortality rate did not differ between the cavernoma and control group (25% versus 12.5%, p = 0.137). Multivariable Cox proportional hazard regression analyses revealed that 5-day treatment failure (HR = 1.223, 95% CI = 1.082 to 1.384; p = 0.001) independently predicted 6-week mortality. Cirrhotic patients with AVB and portal cavernoma have worse short-term prognosis than patients without portal cavernoma. The 5-day treatment failure was an independent risk factor for 6-week mortality in patients with cirrhosis and portal cavernoma.

    Abstract This study was aimed to determine the risk factors of endoscopic variceal ligation-(EVL) induced ulcer bleeding. The prevalence of EVL-induced ulcer bleeding is reported to be 3.6%. However, there are only limited reports of this serious complication, and the risk factors and the treatment methods are not well established. A total of 430 patients who had undergone EVL in Chonnam National University Hospital from January 2014 to October 2016 were studied. EVL was performed for prophylaxis or acute hemorrhage. The patients were classified into 2 groups: a bleeding group (n = 33) and a non-bleeding group (n = 397). The patients who had endoscopically confirmed EVL-induced ulcer bleeding were included in the bleeding group. EVL-induced ulcer bleeding occurred in 7.7% (n = 33) of the patients. In a multivariate analysis, model for end-stage liver disease (MELD) score >10 (odds ratio [OR]: 3.42, 95% confidence interval [CI]: 1.10–10.64), concomitant GV F3 (OR: 14.1, 95% CI: 2.84–71.43), and detachment of o-ring bands on follow-up endoscopy (OR: 8.06, 95% CI: 2.55–25.64) were independent predictive factors of EVL-induced ulcer bleeding. Various endoscopic modalities were attempted for hemostasis (EVL in 8 cases [24.2%], endoscopic variceal obturation [EVO] with cyanoacrylate in 6 cases [18.2%], argon plasma coagulation [APC] in 1 case (3%), Sengstaken–Blakemore (SB) tube in 3 cases [9.1%]), and proton pump inhibitor therapy only in 15 cases (45.5%). MELD score >10, concomitant GV F3, and detachment of o-ring bands on follow-up endoscopy are risk factors for EVL-induced ulcer bleeding. PMID:28614248

    Stomal variceal bleeding can develop in patients with underlying cirrhosis and portal hypertension. Most patients are best treated with transjugular intrahepatic portosystemic shunt (TIPS) creation because this addresses the underlying problem of portal hypertension. However, some patients are not good candidates for TIPS creation because they have end-stage liver disease or encephalopathy. We describe such a patient who presented with recurrent bleeding stomal varices, which was successfully treated with percutaneous coil embolization. The patient had bleeding-free survival for 1 month before death from unrelated causes.

    We report a 64-year-old woman with duodenal varices who underwent balloon-occluded retrograde transvenous obliteration (B-RTO) complicated by intraprocedural variceal rupture. The patient developed shivering and a fever higher than 40{sup o}C 3 days after the B-RTO procedure. A blood culture grew Entereobacter cloacoe. This case represents a rare septic complication of B-RTO for duodenal varices.

    Data regarding agreement on endoscopic features of oesophageal varices in children with portal hypertension (PH) are scant. The aim of this study was to evaluate endoscopic visualisation and classification of oesophageal varices in children by several European clinicians, to build a rational basis for future multicentre trials. Endoscopic pictures of the distal oesophagus of 100 children with a clinical diagnosis of PH were distributed to 10 endoscopists. Observers were requested to classify variceal size according to a 3-degree scale (small, medium, and large, class A), a 2-degree scale (small and large, class B), and to recognise red wales (presence or absence, class Red). Overall agreement was considered fair if Fleiss and Cohen κ test was ≥0.30, good if ≥0.40, excellent if ≥0.60, and perfect if ≥0.80. Agreement between observers was fair with class A (κ = 0.34) and class B (κ = 0.38), and good with class Red (κ = 0.49). The agreement was good on presence versus absence of varices (class A = 0.53, class B = 0.48). The agreement among the observers was good in class A when endoscopic features of severe PH (medium and large sizes, red marks) were grouped and compared with mild features (absent and small varices) (κ = 0.58). Experts working in different centres show a fairly good agreement on endoscopic features of PH in children, although a better training of paediatric endoscopists may improve the agreement in grading severity of varices in this setting.

    We report the case of an otherwise healthy 29-year-old woman who presented with a brainstem haemorrhage following intravenous methamphetamine use. Extensive investigation did not reveal an underlying pathology, and the development of symptoms was temporally related to methamphetamine injection. Although intracerebral haemorrhage secondary to methamphetamine use is well documented, this report describes a haemorrhage within the brainstem which is a rare location. While animal studies have demonstrated the potential of methamphetamines to produce brainstem haemorrhages, there has only been one previous report describing a haemorrhage in this location due to amphetamine use in humans. We conclude with a brief discussion of the clinical features and aetiology of methamphetamine-related stroke. Copyright © 2016 Elsevier Ltd. All rights reserved.

    Recently it has been recommended that all cirrhotic patients without previous variceal hemorrhage undergo endoscopic screening to detect varices and that those with large varices should be treated with beta-blockers (American College of Gastroenterology guidelines). However, endoscopic screening only of patients at highest risk for varices may be the most cost effective. Ninety-eight patients without a history of variceal hemorrhage underwent esophagogastroduodenoscopy as part of a liver transplant evaluation. Univariate/multivariate analysis was used to evaluate associations between the presence of varices and patient characteristics including etiology of liver disease, Child-Pugh class, physical findings (spider angiomata, splenomegaly, and ascites), encephalopathy, laboratory parameters (prothrombin time, albumin, bilirubin, BUN, creatinine, and platelets), and abdominal ultrasound findings (portal vein diameter/flow, splenomegaly, and ascites). The causes of cirrhosis among the 67 men and 31 women (mean age, 48 yr) included 28% Hepatitis C/alcoholism, 25% Hepatitis C, 13% alcoholism, 9% primary sclerosing cholangitis/primary biliary cirrhosis, 9% cryptogenic, 6% Hepatitis B, 1% Hepatitis B and C, and 9% other. Patients were Child-Pugh class A 34%, B 51%, and C 15%. Endoscopic findings included esophageal varices in 68% of patients (30% were large), gastric varices in 15%, and portal hypertensive gastropathy in 58%. Platelet count <88,000 was the only parameter identified by univariate/multivariate analysis (p < 0.05) as associated with the presence of large esophageal varices (odds ratio 5.5; 95% confidence interval 1.8-20.6) or gastric varices (odds ratio 5; 95% confidence interval 1.4-23). Platelet count <88,000 is associated with the presence of esophagogastric varices. A large prospective study is needed to verify and validate these findings and may allow identification of a group of patients who would most benefit from endoscopic screening for varices.

    Laparoscopic surgery for patients with portal hypertension is considered to be contraindicated because of the high risk of massive intraoperative hemorrhaging. However, recent reports have shown hand-assisted laparoscopic surgery for devascularization and splenectomy to be a safe and effective method of treating esophagogastric varices with portal hypertension. The aim of this study is to evaluate the efficacy of hand-assisted laparoscopic devascularization and splenectomy (HALS Hassab's procedure) for the treatment of esophagogastric varices with portal hypertension. From 2009 to 2016, seven patients with esophagogastric varices with portal hypertension were treated with hand-assisted laparoscopic devascularization and splenectomy in our institute. Four men and three women with a median age of 61 years (range 35-71) were enrolled in this series. We retrospectively reviewed the medical records for the perioperative variables, postoperative mortality and morbidity, and postoperative outcomes of esophagogastric varices. The median operative time was 455 (range 310-671) min. The median intraoperative blood loss was 695 (range 15-2395) ml. The median weight of removed spleen was 507 (range 242-1835) g. The conversion rate to open surgery was 0%. The median postoperative hospital stay was 21 (range 13-81) days. During a median 21 (range 3-43) months of follow-up, the mortality rate was 0%. Four postoperative complications (massive ascites, enteritis, intra-abdominal abscess, and intestinal ulcer) were observed in two patients. Those complications were treated successfully without re-operation. Esophagogastric varices in all patients disappeared or improved. Bleeding from esophagogastric varices was not observed during the follow-up period. Although our data are preliminary, hand-assisted laparoscopic devascularization and splenectomy proved an effective procedure for treating esophagogastric varices in patients with portal hypertension.

    Endoscopy is recommended to screen for esophageal varices in patients with cirrhosis. The objective of this study was to identify features on abdominal CT imaging associated variceal hemorrhage (VH). A case-control study was performed among patients with cirrhosis who had a CT scan. Consecutive patients who experienced VH were included as cases, and patients without VH served as controls. Two radiologists recorded the maximal esophageal varix diameter in addition to other measures of portal hypertension at CT. The most powerful CT parameter associated with VH was the esophageal varix diameter (5.8 vs. 2.7 mm, p < 0.001; adjusted OR 1.84 per mm, p = 0.009). 63% of individuals with VH had a maximal varix diameter ≥5 mm compared to 7.5% of cirrhotic patients without VH (p < 0.001). In contrast, the proportion of individuals whose largest varix was <3 mm was 7.4% among VH cases compared to 54.7% among controls (p = 0.001). The varix diameter powerfully discriminated those with and without VH (C-statistic 0.84). A large esophageal varix diameter is strongly associated with subsequent VH. A threshold of <3 and ≥5 mm appears to identify patients with cirrhosis at low and high risk for hemorrhage.

    Haemorrhage remains a leading cause of maternal death. We conducted an audit to identify strategies to improve the management at our local NHS Trust. A data collection form was based on our local guideline. A coded database search was conducted for all deliveries where the estimated blood loss was ≥2000 ml (from June 1 2015 to December 31 2015), returning 68 search results (13.7/1000 births). Fifty-six records were included. Poor compliance (<75%) was seen in some key areas including the major obstetric haemorrhage (MOH) call activation (52%), the presence of an anaesthetic consultant (63%) and tranexamic acid administration (46%). Thirty out of 56 cases (54%) were acutely transfused. Women, who were not transfused acutely, appeared to be more likely to need a secondary transfusion if no MOH call had been activated (9/27 (33%) versus 3/29 (10%), p = .052). A key area for improvement was the activation of MOH calls. Following this audit, we adjusted our guideline to make it more clinically useful and staff training sessions were held, including simulation training. Impact statement What is already known on this subject? A postpartum haemorrhage (PPH) is an obstetric emergency. A structured approach is important to optimise the care of the mothers during this dangerous time, and has been shown to reduce the transfusion requirements. However, clinical practice may not adhere to the guideline recommendations. What the results of this study add? With the objective evidence of increased rates of PPH ≥2000 ml at our institution, our work identifying the flaws in management was a critical component of the work to improve the outcomes. This study gives impetus to find innovative ways to improve adherence to guidelines, and inspired an update of our local guideline to improve the applicability and utility. This project suggests a new marker for the adequacy of an acute management (a requirement for secondary blood transfusion without having received an acute

    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.

    Ectopic variceal bleeding is a rare (2-5%) but fatal gastrointestinal bleed in patients with portal hypertension. Patients with ectopic variceal bleeding manifest melena, hematochezia, or hematemesis, which require urgent managements. Definitive therapeutic modalities of ectopic varices are not yet standardized because of low incidence. Various therapeutic modalities have been applied on the basis of the experiences of experts or availability of facilities, with varying results. We have encountered eight cases of gastrointestinal ectopic variceal bleeding in five patients in the last five years. All patients were diagnosed with liver cirrhosis presenting melena or hematemesis. All patients were treated with various endoscopic modalities (endoscopic variceal obturation [EVO] with cyanoacrylate in five cases, endoscopic variceal band ligation (EVL) in two cases, hemoclipping in one case). Satisfactory hemostasis was achieved without radiologic interventions in all cases. EVO and EVL each caused one case of portal biliopathy, and EVL induced ulcer bleeding in one case. EVO generally accomplished better results of variceal obturations than EVL or hemoclipping, without serious adverse events. EVO may be an effective modality for control of ectopic variceal bleeding without radiologic intervention or surgery.

    This study aimed to assess the role of endoscopic ultrasonography (EUS) in the surgical management of isolated gastric varices (IGV), and to report the authors' experience in the treatment of IGV with modified devascularization surgery. In this study, 26 cirrhotic patients with IGV were treated with devascularization surgery for variceal hemorrhage. Preoperatively, percutaneous transhepatic portography (PTP) and EUS were used to determine the mode of therapy for IGV. Fundectomy was performed for 14 patients with fundic IGV, whereas 12 patients with cardiac IGV underwent proximal gastrectomy. A significantly higher proportion of patients with cardiac varices showed grade 3 IGV on preoperative EUS than those who had fundic varices (p < 0.05). No major complications were observed during or after the operation, and only one patient died of prolonged shock and massive transfusion. Postoperatively, gastric varices had been eradicated completely in 25 of 26 patients, as determined by EUS study. During a mean follow-up period of 50 months, two patients had recurrent varices without bleeding, as demonstrated by EUS. The overall 5-year survival rate for the fundic IGV group was 67.9%, whereas that for the cardiac IGV group was 64.3% (p > 0.05). This study showed that devascularization surgery is highly effective for the prevention of recurrent bleeding from IGV and provides an alternative treatment method. Preoperatively, EUS is very helpful in detailed devascularization of patients with specific IGV, and may be used also for postoperative follow-up evaluation.

    In dogs with idiopathic acute haemorrhagic diarrhoea syndrome (AHDS), a serious loss of intestinal mucosal barrier integrity occurs. However, the incidence of bacterial translocation in dogs with idiopathic AHDS is not known. Thus, the objectives of this prospective study were to identify the incidence of bacteraemia, to evaluate the frequency of septic events and the influence of bacteraemia on various clinical and laboratory parameters, duration of hospitalisation and survival of dogs with idiopathic AHDS. The study included 87 dogs with idiopathic AHDS. Twenty-one healthy dogs served as control group. To evaluate clinical significance of bacterial translocation, blood culture results were compared between patients and controls. Clinical and laboratory parameters were compared between patients with positive and negative blood cultures. There was no significant difference in either incidence of bacteraemia between patients with idiopathic AHDS (11 per cent) and controls (14 per cent) or in severity of clinical signs, laboratory parameters, duration of hospitalisation or mortality between blood culture-positive and culture-negative dogs with idiopathic AHDS. The results of this study suggest that the incidence of bacteraemia in dogs with idiopathic AHDS is low and not different from that of healthy control dogs. Bacteraemia does not influence the clinical course or survival and thus antibiotic treatment is not indicated to prevent sepsis. British Veterinary Association.

    Platelet function might play an essential role in the pathogenesis of delayed cerebral ischemia (DCI) after aneurysmal subarachnoid haemorrhage (SAH). Thus, impaired platelet function and disturbed primary haemostasis induced by intake of acetylsalicylic acid (ASA) might influence the rate of DCI. Primary haemostasis and platelet function can be measured with in vitro diagnosis (platelet function analyser test, PFA 100). The aim of this study is to evaluate the rate of DCI, haemorrhagic complications and the neurological outcome. Two groups were compared (patients with regular platelet function versus patients with impaired platelet function). This is a retrospective observational study. An initial cohort of 787 patients with SAH has been treated from January 2005 to September 2012. Seventy-nine patients (10%) with aneurysmal SAH, a history of ASA medication and PFA testing within the first 24 h after aneurysm rupture have been included. The overall rate of DCI in the present study was 43%. In vitro platelet function testing showed pathological primary haemostasis in 69.6%. The DCI rate was higher in patients with regular tested primary haemostasis (p = 0.02, OR = 3.16, 95%CI = [1.19; 8.83]). However, outcome assessment by mGOS did not show a significant difference between the groups. Patients with impaired primary haemostasis did not display a higher rate of haemorrhagic complications. Impairment of primary haemostasis resulting from an impairment of platelet function at an early stage after SAH might lead to a lower rate of DCI. In vitro testing of platelet function might be useful to predict the occurrence of DCI in the course.

    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

    Gastroesophageal variceal hemorrhage is a medical emergency with high morbidity and mortality. Endoscopic therapy is the mainstay of management of bleeding varices. It requires attention to technique and the appropriate choice of therapy for a given patient at a given point in time.

    OBJECTIVES: To describe the technical feasibility, safety, and clinical outcomes of coil-assisted retrograde transvenous obliteration (CARTO) in treating portal hypertensive non-esophageal variceal hemorrhage. METHODS: From October 2012 to December 2013, 20 patients who received CARTO for the treatment of portal hypertensive non-esophageal variceal bleeding were retrospectively evaluated. All 20 patients had at least 6-month follow-up. All patients had detachable coils placed to occlude the efferent shunt and retrograde gelfoam embolization to achieve complete thrombosis/obliteration of varices. Technical success, clinical success, rebleeding, and complications were evaluated at follow-up. RESULTS: A 100% technical success rate (defined as achieving complete occlusion of efferent shunt with complete thrombosis/obliteration of bleeding varices and/or stopping variceal bleeding) was demonstrated in all 20 patients. Clinical success rate (defined as no variceal rebleeding) was 100%. Follow-up computed tomography after CARTO demonstrated decrease in size with complete thrombosis and disappearance of the varices in all 20 patients. Thirteen out of the 20 had endoscopic confirmation of resolution of varices. Minor post-CARTO complications, including worsening of esophageal varices (not bleeding) and worsening of ascites/hydrothorax, were noted in 5 patients (25%). One patient passed away at 24 days after the CARTO due to systemic and portal venous thrombosis and multi-organ failure. Otherwise, no major complication was noted. No variceal rebleeding was noted in all 20 patients during mean follow-up of 384±154 days. CONCLUSIONS: CARTO appears to be a technically feasible and safe alternative to traditional balloon-occluded retrograde transvenous obliteration or transjugular intrahepatic portosystemic shunt, with excellent clinical outcomes in treating portal hypertensive non-esophageal variceal bleeding.

    Spinal cord haemangioblastomas are rare central nervous systems tumours, and haemorrhage.It is an uncommon occurance. We report a 28-year-old pregnant patient who presented with paraplegia due to acute haemorrhage of a spinal haemangioblastoma. Magnetic resonance imaging showed extensive syrinx cavities, an intramedullary lesion at the T4-T5 spinal cord level e, and a subarachnoid haemorrhage. Digital subtraction angiography showed the feeding artery and dilated tortuous draining vein within the dural sac. The lesion was deemed a haemangioblastoma. The histopathological examination confirmed the diagnosis. Postoperatively, the paraplegia improved and the patient was able to walk within 2 weeks. Imaging is important for early diagnosis to prevent patients persistent neurological deficits.

    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.

  1. Prevention of Portal Hypertension: from Variceal Development to Clinical Decompensation

    2015-01-01

    Pharmacological treatment of portal hypertension (PH) has been exclusively devoted to gastro-esophageal varices related events at different frameworks including prophylactic, emergency or preventive therapy. The goals of treatment are to avoid the first bleeding episode, stop active bleeding and prevent bleeding recurrence, respectively. The objective of pre-primary prophylaxis (PPP) is to avoid variceal development and therefore, it necessarily deals with cirrhotic patients at earlier stages of the disease. At these earlier stages, nonselective beta blocker (NSBB) have been ineffective in preventing the development of varices and other complications of PH. Therefore, treatment should not rely on NSBB. It is possible, that at these earlier stages, etiological treatment of liver disease itself could prevent the progression of PH. This review will focus mainly on early treatment of PH, because if successful, it may translate into histological-hemodynamic improvements, avoiding not only variceal development but also other PH related complications, such as ascites and porto-systemic encephalopathy (PSE). Moreover, the advent of new therapies may allow not only the prevention of the complications of PH, but also the chance of a substantial degree of regression in the cirrhotic process with the possible prevention of hepatocellular carcinoma (HCC).

    This report describes a 38-year-old man with massive gastrointestinal bleeding from jejunal varices. He had been previously diagnosed to have idiopathic portal hypertension and esophageal varices, and had undergone an esophageal transection 8 years earlier. The pre-operative diagnosis was a suspected hemorrhage from the small intestine as visualized by 99mTc-HSAD scintigraphy (technetium 99m-labeled human serum albumin D-type) and was not considered to be repeated massive lower GI tract bleeding. An exploratory laparotomy was performed, and intra-operative endoscopy revealed active bleeding from the jejunal varices. A partial resection of the small intestine resulted in a complete resolution of the bleeding. A review of the literature thereafter disclosed twelve previously reported cases of jejunal variceal bleeding.

    Primary prophylaxis of bleeding is debated for children with portal hypertension because of the limited number of studies on its safety and efficacy, the lack of a known endoscopic pattern carrying a high-risk of bleeding for all causes, and the assumption that the mortality of a first bleed is low. We report our experience with these issues. From 1989 to 2014, we managed 1300 children with portal hypertension. Endoscopic features were recorded; high-risk varices were defined as: grade 3 esophageal varices, grade 2 varices with red wale markings, or gastric varices. Two hundred forty-six children bled spontaneously and 182 underwent primary prophylaxis. The results of primary prophylaxis were reviewed as well as bleed-free survival, overall survival and life-threatening complications of bleeding. High-risk varices were found in 96% of children who bled spontaneously and in 11% of children who did not bleed without primary prophylaxis (p<0.001), regardless of the cause of portal hypertension. Life-threatening complications of bleeding were recorded in 19% of children with cirrhosis and high-risk varices who bled spontaneously. Ten-year probabilities of bleed-free survival after primary prophylaxis in children with high-risk varices were 96% and 72% for non-cirrhotic causes and cirrhosis respectively. Ten-year probabilities of overall survival after primary prophylaxis were 100% and 93% in children with non-cirrhotic causes and cirrhosis respectively. In children with portal hypertension, bleeding is linked to the high-risk endoscopic pattern reported here. Primary prophylaxis of bleeding based on this pattern is fairly effective and safe. In children with liver disease, the risk of bleeding from varices in the esophagus is linked to their large size, the presence of congestion on their surface and their expansion into the stomach but not to the child's age nor to the cause of portal hypertension. Prevention of the first bleed in children with high-risk varices can

    Renin-angiotensin-system blockers are thought to increase the risk of acute kidney injury after surgery and haemorrhage. We found that Losartan does not cause renal cortical hypoxia after haemorrhage in rats because of decreased renal vascular resistance, but did not evaluate resuscitation. Study Losartan´s effect on renal cortical and medullary oxygenation, and norepinephrine´s vasopressor effect in a model of resuscitated haemorrhage. After seven days Losartan (60 mg/kg/day) or control treatment, male Wistar rats were haemorrhaged 20 % of the blood volume and resuscitated with Ringer's Acetate. Mean arterial pressure, renal blood flow, and kidney tissue oxygenation was measured at baseline and after resuscitation. Finally, the effect of norepinephrine on mean arterial pressure and renal blood flow was investigated. As expected, Losartan lowered mean arterial pressure but not renal blood flow. Losartan did not affect renal oxygen consumption and oxygen tension. Mean arterial pressure and renal blood flow were lower after resuscitated haemorrhage. Smaller increase of renal vascular resistance in Losartan group translated to smaller decrease in cortical oxygen tension, but no significant difference seen in medullary oxygen tension either between groups or after haemorrhage. The effect of norepinephrine on mean arterial pressure and renal blood flow was similar in controls and Losartan treated rats. Losartan does not decrease renal oxygenation after resuscitated haemorrhage because of a smaller increase in renal vascular resistance. Further, Losartan does not decrease the efficiency of norepinephrine as a vasopressor indicating that blood pressure may be managed effectively during Losartan treatment.

    Band ligation (BL) is the most appropriate endoscopic treatment for acute bleeding or prophylaxis of esophageal variceal bleeding. Sclerotherapy with N-butyl-2-cyanoacrylate (CY) can be an alternative for patients with advanced liver disease. Bacteremia is an infrequent complication after BL while the bacteremia rate following treatment with CY for esophageal varices remains unknown. To evaluate and compare the incidence of transient bacteremia between cirrhotic patients submitted to diagnostic endoscopy, CY and BL for treatment of esophageal varices. A prospective study comprising the period from 2004 to 2007 was conducted at Hospital of Universidade Federal de São Paulo, UNIFESP, SP, Brazil. Cirrhotic patients with advanced liver disease (Child-Pugh B or C) were enrolled. The patients were divided into two groups according treatment: BL Group (patients undergoing band ligation, n = 20) and CY Group (patients receiving cyanoacrylate injection for esophageal variceal, n = 18). Cirrhotic patients with no esophageal varices or without indication for endoscopic treatment were recruited as control (diagnostic group n = 20). Bacteremia was evaluated by blood culture at baseline and 30 minutes after the procedure. After 137 scheduled endoscopic procedures, none of the 58 patients had fever or any sign suggestive of infection. All baseline cultures were negative. No positive cultures were observed after CY or in the control group - diagnostic endoscopy. Three (4.6 %) positive cultures were found out of the 65 sessions of band ligation (P = 0.187). Two of these samples were positive for coagulase-negative staphylococcus, which could be regarded as a contaminant. The isolated microorganism in the other case was Klebsiella oxytoca. The patient in this case presented no evidence of immunodeficiency except liver disease. There was no significant difference in bacteremia rate between these three groups. BL or CY injection for non-bleeding esophageal varices may be considered

    Portal hypertension can lead to oesophageal varices (EV) and portal hypertensive gastropathy (PHG). The aim of this study is to determine the relationship between severity of Portal hypertensive gastropathy and size of oesophageal varices. One hundred and ninety-five patients of hepatitis C positive chronic liver disease having oesophageal varices were assessed for severity of portal hypertensive gastropathy. Mild Portal Hypertensive Gastropathy was observed in 16 (8.2 %), moderate in 54 (27.7 %) and severe in 120 (61.6 %) patients. Grade 1 Oesophageal Varices were present in 79 (40.5%) patients, grade 2 in 44 (21.9%) patients, grade 3 in 62 (31.8%) and grade 4 in 10 (5.2%) patients. No significant correlation was observed between grades of gastropathy and size of varices. The frequency of portal hypertensive gastropathy was 97.5% in Hepatitis C positive cirrhotic patients having oesophageal varices. Severity of gastropathy is not related to the grade or size of oesophageal varices.

    This study aims to clarify the long-term outcome of therapeutic strategies including balloon-occluded retrograde transvenous obliteration (B-RTO) for patients with gastric fundal varices. The subjects were 154 patients with gastric fundal varices fulfilling the criteria for receiving B-RTO. In patients showing variceal bleeding, endoscopic therapies and/or balloon tamponade was performed to achieve hemostasis. B-RTO was accomplished with injection of 5% ethanolamine oleate through a standard balloon catheter except for patients with atypical varices, in whom a microballoon catheter was used to occlude drainage vessels other than a gastrorenal shunt. In patients complicated with esophageal varices at baseline, endoscopic therapies were performed following B-RTO. Balloon-occluded retrograde transvenous obliteration was performed successfully in 147 patients (95%), including 15 patients using a microballoon catheter. Complete variceal obliteration was achieved in all patients. Additional endoscopic therapies for esophageal varices were performed in 31 patients. Gastric varices did not recur in any of these patients. The cumulative survival rates at 1, 3, and 5 years after B-RTO were 91%, 76%, and 72%, respectively. Child-Pugh scores and hepatocellular carcinoma complication were identified as prognostic factors associated with survival rates. The cumulative exacerbation rates of esophageal varices at 1, 3, and 5 years were 13%, 20%, and 27%, respectively, and rupture developed in six patients, which were successfully treated with endoscopic therapies. Therapeutic strategies including B-RTO with a microballoon catheter were useful to achieve a favorable outcome in patients with gastric fundal varices especially in those manifesting Child-Pugh class-A liver damage and/or those without hepatocellular carcinoma complication. © 2016 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

A 17-year-old boy presented to the emergency department with complaints of redness in both eyes and vomiting. He had bilateral eyelid ecchymosis with subconjunctival haemorrhage. Complete blood count revealed a significantly reduced platelet count of 11000/µL suggestive of dengue haemorrhagic fever (DHF). Ocular manifestations were followed by other systemic haemorrhagic manifestations of dengue later on which violates the usual sequence of events of dengue fever. Bilateral eyelid ecchymosis is a rare clinical manifestation and a rare presenting feature of dengue fever and one has to keep high index of suspicion for presence of dengue whenever a case of fever presents with lid ecchymosis/haemorrhage. © The Author(s) 2014.

    1987-01-01

    To assess whether Valsalva's manoeuvre might cause variceal bleeding, 22 patients with oesophageal varices were studied. In 12 patients who received no previous treatment to their varices the median pressure gradient across the varix wall at rest was 19 (6-36) mmHg, and in 10 patients whose varices were thrombosed at their distal end the median pressure gradient in the proximal patent varix was 8 (1-6) mmHg. In untreated patients groups, the pressure gradient rose by 6-12 mmHg during Valsalva's manoeuvre in four patients, fell by 4-11 mmHg in five patients and was virtually unchanged in the remainder. These changes seem unlikely to cause variceal bleeding. Patients who repeated Valsalva's manoeuvre showed similar changes on each occasion. Six patients in the untreated group also received hyoscinbutylbromide 20 mg iv. No change was seen in the pressure gradient in five patients, suggesting that it is of little value in preventing variceal bleeding. PMID:3500098

    Bleeding esophageal and gastric varices constitute a serious complication in liver cirrhosis. Previous studies have shown that endoscopic ultrasonography (EUS) can be used to predict early esophageal variceal bleeding in liver cirrhosis. We report a case of a 46-year-old man with hepatitis B liver cirrhosis (CTP score, 5; Child-Pugh class, A) who was admitted to our hospital due to a decreased appetite lasting 1 week. He was initially diagnosed with decompensated hepatitis B cirrhosis; an abdominal computed tomography (CT) scan indicated a diagnosis of liver cirrhosis and portal hypertension (PHT). Common endoscopic examination showed no evidence of gastroesophageal varices; EUS revealed distinct varices of the esophageal and gastric veins. Six months after discharge, the patient was rehospitalized because of upper gastrointestinal bleeding. Endoscopic ligation was implemented as well as esophageal varices loop ligature (EVL). Six months later, EUS showed obvious collateral and perforator veins. We should strongly recommend that patients with liver cirrhosis undergo EUS in addition to a routine endoscopic examination. EUS can play an important role in evaluating the risk for bleeding in PHT and can be used to assess the efficacy of EVL.

    Current guidelines do not differentiate in the utilization of vasoactive drugs in patients with cirrhosis and acute variceal bleeding (AVB) depending on liver disease severity. In this retrospective study, clinical outcomes in 100 patients receiving octreotide plus endoscopic therapy (ET) and 216 patients with ET alone were compared in terms of failure to control bleeding, in-hospital mortality, and transfusion requirements stratifying the results according to liver disease severity by Child-Pugh (CP) score and MELD. In patients with CP-A or those with MELD < 10 octreotide was not associated with a better outcome compared to ET alone in terms of hospital mortality (CP-A: 0.0 vs. 0.0%; MELD < 10: 0.0 vs. 2.9%, p = 1.00), failure to control bleeding (CP-A: 8.7 vs. 3.7%, p = 0.58; MELD < 10: 5.3 vs. 4.3%, p = 1.00) and need for transfusion (CP-A: 39.1 vs. 61.1%, p = 0.09; MELD < 10: 63.2 vs. 62.9%, p = 1.00). Those with severe liver dysfunction in the octreotide group showed better outcomes compared to the non-octreotide group in terms of hospital mortality (CP-B/C: 3.9 vs. 13.0%, p = 0.04; MELD ≥ 10: 3.9 vs. 13.3%, p = 0.03) and need for transfusion (CP-B/C: 58.4 vs. 71.6%, p = 0.05; MELD ≥ 10: 50.6 vs. 72.7%, p < 0.01). In multivariate analysis, octreotide was independently associated with in-hospital mortality (p = 0.028) and need for transfusion (p = 0.008) only in patients with severe liver dysfunction (CP-B/C or MELD ≥ 10). Patients with cirrhosis and AVB categorized as CP-A or MELD < 10 had similar clinical outcomes during hospitalization whether or not they received octreotide.

    The objective of this study was to analyse whether the number of admissions for gastrointestinal bleeding to our bleeding unit increases during the full moon. In a prospective study, we included 447 consecutive patients with gastrointestinal haemorrhage admitted to our bleeding unit during a period of two years. The number of admissions was allocated to the corresponding day of the lunar cycle, and full moon and non-full moon days were compared. A wide variation in the number of admissions throughout the lunar cycle was observed. There were 26 admissions on the 25 days of full moon and 421 admissions in the remaining 713 days of non-full moon. This difference was mainly related to a higher incidence of haemorrhage in men and variceal haemorrhage at full moon. The results of this study suggest an increase in the number of admissions related to gastrointestinal haemorrhage in our bleeding unit during the full moon, especially in men and in patients experiencing variceal haemorrhage. However, the wide variation in the number of admissions throughout the lunar cycle could limit interpretation of the results. Therefore, further studies are needed to clarify the possible influence of the moon on gastrointestinal haemorrhage.

    Patients with upper gastrointestinal bleeding (UGIB) require an early, tailored approach best guided by knowledge of the bleeding lesion, especially a variceal versus a nonvariceal source. To identify, by investigating a large national registry, variables that would be predictive of a variceal origin of UGIB using clinical parameters before endoscopic evaluation. A retrospective study was conducted in 21 Canadian hospitals during the period from January 2004 until the end of May 2005. Consecutive charts for hospitalized patients with a primary or secondary discharge diagnosis of UGIB were reviewed. Data regarding demographics, including historical, physical examination, initial laboratory investigations, endoscopic and pharmacological therapies administered, as well as clinical outcomes, were collected. Multivariable logistic regression modelling was performed to identify clinical predictors of a variceal source of bleeding. The patient population included 2020 patients (mean [± SD] age 66.3±16.4 years; 38.4% female). Overall, 215 (10.6%) were found to be bleeding from upper gastrointestinal varices. Among 26 patient characteristics, variables predicting a variceal source of bleeding included history of liver disease (OR 6.36 [95% CI 3.59 to 11.3]), excessive alcohol use (OR 2.28 [95% CI 1.37 to 3.77]), hematemesis (OR 2.65 [95% CI 1.61 to 4.36]), hematochezia (OR 3.02 [95% CI 1.46 to 6.22]) and stigmata of chronic liver disease (OR 2.49 [95% CI 1.46 to 4.25]). Patients treated with antithrombotic therapy were more likely to experience other causes of hemorrhage (OR 0.44 [95% CI 0.35 to 0.78]). Presenting historical and physical examination data, and initial laboratory tests carry significant predictive ability in discriminating variceal versus nonvariceal sources of bleeding.

    Gastroesophageal variceal hemorrhage is a common complication of portal hypertension. Endoscopic therapy is currently recommended for preventing gastroesophageal variceal rebleed. However, the rate of variceal rebleed and its associated mortality remain concerning. This study is aimed at differentiating patient response to endoscopic therapy based on endoscopic ultrasound (EUS) findings. One-hundred seventy patients previously treated with repeat endoscopic therapy for secondary prophylaxis were enrolled and classified into two groups based on treatment response. Prior to consolidation therapy, all patients received an EUS examination to observe for extraluminal phenomena. All available follow-up endoscopic examination records were retrieved to validate study results. Of the 170 subjects, 106 were poor responders, while 64 were good responders. The presence of para-gastric, gastric perforating, and esophageal perforating veins was associated with poor patient response (p<0.001). The odds ratio for para-gastric veins was 5.374. Follow-up endoscopic findings for poor responders with incomplete variceal obliteration was closely correlated with the presence of para-gastric veins (p=0.002). The presence of para-gastric veins is a characteristic of poor response to endoscopic therapy for treating gastroesophageal varices. Early identification of this subgroup necessitates a change in course of treatment to improve overall patient outcome.

    The aim of this study is to describe the clinical presentation of vortex vein varices with multimodal imaging. The authors carried out a retrospective case series of eight patients (7 female, 1 male) with an average age of 60.2 years (min 8, max 84, median 68.5) presenting with vortex vein varices. All patients were evaluated at the Sant'Orsola-Malpighi Hospital, University of Bologna, Bologna, Italy and at Luigi Sacco Hospital, University of Milan, Milan, Italy. Patients underwent complete ophthalmologic examinations, including best corrected visual acuity, intraocular pressure, anterior segment, and fundus examination. Imaging studies, including fundus color photography, near-infrared reflectance imaging, fundus autofluorescence, fluorescein angiography, indocyanine green angiography, and spectral-domain enhanced depth imaging optical coherence tomography were also performed. Ultra-widefield fluorescein angiography and ultra-widefield indocyanine angiography using the Heidelberg Retina Angiograph and the Staurenghi 230 SLO Retina Lens were used to demonstrate the disappearance of all retinal lesions when pressure was applied to the globe. All eight cases initially presented to the emergency room. One patient presented secondary to trauma, two patients presented for suspected hemangioma, whereas the other five were referred to the authors' hospitals for suspected retinal lesions. On examination, retinal abnormalities were identified in all 8 patients, with 7 (87.5%) oculus dexter and 1 (12.5%) oculus sinister, and with 1 (12.5%) inferotemporally, 3 (37.5%) superonasally, 3 (37.5%) inferonasally, and 1 (12.5%) inferiorly. Fundus color photography showed an elevated lesion in seven patients and a nonelevated red lesion in one patient. In all patients, near-infrared reflectance imaging showed a hyporeflective lesion in the periphery of the retina. Fundus autofluorescence identified round hypofluorescent rings surrounding weakly hyperfluorescent lesions in all

    Dengue infections are a major cause of morbidity and mortality in the tropical and sub-tropical regions of the world. There is no vaccine for dengue and also there are no anti-viral drugs to treat the infection. Some patients, typically those experiencing a secondary infection with a different dengue serotype, may progress from an acute febrile disease to the more severe forms of disease, dengue haemorrhagic fever and dengue shock syndrome. Here we discuss the significant immunopathological component to severe disease and how T cells, cytokines and cross-reactive antibody combine to contribute to the progression to dengue haemorrhagic fever. These events are thought to lead to vascular leakage, the signature event in dengue haemorrhagic fever, and are addressed in this review by incorporating the concept of heterologous T cell immunity. The need for effective measures against dengue and dengue-related illness is clear. We propose that drugs against dengue virus, or the symptoms of severe dengue disease, are a viable goal.

    The international normalized ratio (INR) has not been validated as a predictor of bleeding risk in cirrhotics. The aim of this study was to determine whether elevation in the INR correlated with risk of esophageal variceal hemorrhage and whether correction of the INR prior to endoscopic therapy affects failure to control bleeding. Patient records were retrospectively reviewed from January 1, 2000 to December 31, 2010. Cases were cirrhotics admitted to the hospital due to bleeding esophageal varices. Controls were cirrhotics with a history of non-bleeding esophageal varices admitted with ascites or encephalopathy. All variceal bleeders were treated with octreotide, antibiotics, and band ligation. Failure to control bleeding was defined according to the Baveno V criteria. We analyzed 74 cases and 74 controls. The mean INR at presentation was lower in those with bleeding varices compared to non-bleeders (1.61 vs 1.74, P = 0.03). Those with bleeding varices had higher serum sodium (136.1 vs 133.8, P = 0.02), lower hemoglobin (9.59 vs 11.0, P < 0.001), and lower total bilirubin (2.47 vs 5.50, P < 0.001). Multivariable logistic regression showed total bilirubin to inversely correlate with bleeding (OR = 0.74). Bleeders received a mean of 1.14 units of fresh frozen plasma (FFP) prior to endoscopy (range 0-11 units). Of the 14 patients (20%) with failure to control bleeding, median INR (1.8 vs 1.5, P = 0.02) and median units of FFP transfused (2 vs 0, P = 0.01) were higher than those with hemostasis after the initial endoscopy. The INR reflects liver dysfunction, not bleeding risk. Correction of INR with FFP has little effect on hemostasis.

    Balloon-occluded retrograde transvenous obliteration is an established treatment for gastric varices; it has been used more rarely to treat mesenteric varices. We report a 12-year-old girl who had received a living donor liver transplant and suffered melena due to ruptured mesenteric varices. We addressed treatment of the mesenteric varices by retrograde transvenous obliteration of an abdominal wall collateral vein detected by superior mesenteric arteriography.

    PurposeTo address technical feasibility and clinical outcome of transcatheter embolotherapy with N-butyl cyanoacrylate (NBCA) for bleeding ectopic varices.MethodsThe institutional review board approved this retrospective study and waived informed consent. From January 2004 to June 2013, a total of 12 consecutive patients received transcatheter embolotherapy using NBCA for bleeding ectopic varices in our institute. Clinical and radiologic features of the endovascular procedures were comprehensively reviewed.ResultsPreprocedural computed tomography images revealed ectopic varices in the jejunum (n = 7), stoma (n = 2), rectum (n = 2), and duodenum (n = 1). The 12 procedures consisted of solitary embolotherapy (n = 8) and embolotherapy with portal decompression (main portal vein stenting in 3,more » transjugular intrahepatic portosystemic shunt in 1). With regard to vascular access, percutaneous transhepatic access (n = 7), transsplenic access (n = 4), and transjugular intrahepatic portosystemic shunt tract (n = 1) were used. There was no failure in either the embolotherapy or the vascular accesses (technical success rate, 100 %). Two patients died within 1 month from the procedure from preexisting fatal medical conditions. Only one patient, with a large varix that had been partially embolized by using coils and NBCA, underwent rebleeding 5.5 months after the procedure. The patient was retreated with NBCA and did not undergo any bleeding afterward for a follow-up period of 2.5 months. The remaining nine patients did not experience rebleeding during the follow-up periods (range 1.5–33.2 months).ConclusionTranscatheter embolotherapy using NBCA can be a useful option for bleeding ectopic varices.« less

    While the histological effects of endoscopic sclerotherapy in humans have been extensively described, the effects of endoscopic ligation have been reported in only two cases. The purpose of this study was to reconstruct the chronological sequence of histological changes after ligation of esophageal varices. Autopsy specimens from six patients who received ligation of varices from nine hours to 22 months ante-mortem were evaluated for gross and microscopic changes. Early after ligation, the appearance was that of a polyp with its base compressed by the band. Variceal thrombosis was seen on day 2. Varying degrees of ischemic necrosis of the polyp were present on days 0-5. If the bands did not remain in situ for two days (premature loss), necrosis of the polyp and dilated variceal vessels were seen. On day 22, superficial ulcers were observed. After complete healing, fibrosis was seen in the submucosa. The changes seen in the present study are similar to those described in animals. The delay in ulcer healing, compared with the gross changes reported during follow-up endoscopic examinations, may be related to the severity of the underlying illness and the compromised immune status of patients in the present series.

    We set out to validate the accuracy of gravimetric quantification of blood loss during simulated major postpartum haemorrhage and to evaluate the technique in a consecutive cohort of women experiencing major postpartum haemorrhage. The study took part in a large UK delivery suite over a one-year period. All women who experienced major postpartum haemorrhage were eligible for inclusion. For the validation exercise, in a simulated postpartum haemorrhage scenario using known volumes of artificial blood, the accuracy of gravimetric measurement was compared with visual estimation made by delivery suite staff. In the clinical observation study, the blood volume lost during postpartum haemorrhage was measured gravimetrically according to our routine institutional protocol and was correlated with fall in haemoglobin. The main outcome measure was the accuracy of gravimetric measurement of blood loss. Validation exercise: the mean percentage error of gravimetrically measured blood volume was 4.0±2.7% compared to visually estimated blood volume with a mean percentage error of 34.7±32.1%. Clinical observation study: 356 out of 6187 deliveries were identified as having major postpartum haemorrhage. The correlation coefficient between measured blood loss and corrected fall in haemoglobin for all patients was 0.77; correlation was stronger (0.80) for postpartum haemorrhage >1500mL, and similar during routine and out-of-hours working. The accuracy of the gravimetric method was confirmed in simulated postpartum haemorrhage. The clinical study shows that gravimetric measurement of blood loss is correlated with the fall in haemoglobin in postpartum haemorrhage where blood loss exceeds 1500mL. The method is simple to perform, requires only basic equipment, and can be taught and used by all maternity services during major postpartum haemorrhage. Copyright © 2014 Elsevier Ltd.

    Wandering spleen is the displacement of the spleen due to the loss or weakening of the ligaments of the spleen and is seen very rarely with an incidence of less than 0.5 %. It can cause portal hypertension, but gastric variceal hemorrhage is a quite rare condition within the spectrum of this uncommon disease. We report a 22-year-old woman with wandering spleen presenting with life-threatening gastric variceal hemorrhage. Her diagnosis was made by computerized tomography. Endoscopic therapy was not adequate to stop the bleeding, and urgent splenectomy was performed. After surgery she has been well with no symptoms until now.

    To evaluate the results of percutaneous management of ectopic varices, a retrospective review was carried out of 14 patients (9 men, 5 women; mean age 58 years) who between 1992 and 2001 underwent interventional radiological techniques for management of bleeding ectopic varices. A history of prior abdominal surgery was present in 12 of 14 patients. The interval between the surgery and percutaneous intervention ranged from 2 to 38 years. Transhepatic portal venography confirmed ectopic varices to be the source of portal hypertension-related gastrointestinal bleeding. Embolization of the ectopic varices was performed by a transhepatic approach with coil embolization of themore » veins draining into the ectopic varices. Transjugular intrahepatic portosystemic shunt (TIPS) was performed in the standard fashion. Eighteen procedures (12 primary coil embolizations, 1 primary TIPS, 2 re-embolizations, 3 secondary TIPS) were performed in 13 patients. One patient was not a candidate for percutaneous treatment. All interventions but one (re-embolization) were technically successful. In 2 of 18 interventions, re-bleeding occurred within 72 hr (both embolization patients). Recurrent bleeding (23 days to 27 months after initial intervention) was identified in 9 procedures (8 coil embolizations, 1 TIPS due to biliary fistula). One patient had TIPS revision because of ultrasound surveillance findings. New encephalopathy developed in 2 of 4 TIPS patients. Percutaneous coil embolization is a simple and safe treatment for bleeding ectopic varices; however, recurrent bleeding is frequent and reintervention often required. TIPS can offer good control of bleeding at the expense of a more complex procedure and associated risk of encephalopathy.« less

    The hepatic cirrhosis has as one of the main morbid-mortality causes, the portal hypertension with the development of esophageal varices, the possibility of a digestive hemorrhage and worsening of hepatic insufficiency. It is important to identify causal predictive or aggravating factors and if possible to prevent them. In the last years, it has been observed the association of esophageal motor disorders and gastro-esophageal reflux in cirrhotic patients with esophageal varices. To study the prevalence of the esophageal motility disorders and among them, the ineffective esophageal motility, in patients with hepatic cirrhosis and esophageal varices, without previous endoscopic therapeutic and the predictive factors. Prospectively, it has been evaluate 74 patients suffering from liver cirrhosis and esophagic varices, without previous endoscopic treatment. All of them were submitted to a clinical protocol, esophageal manometry and 55 patients also held the ambulatory esophageal pHmetry. Esophageal motility disorders have been found in 44 patients (60%). The most prevalent was the ineffective esophageal motility, observed in 28%. The abnormal reflux disease was diagnosed through the pHmetry in 35% of the patients. There were no correlation between the manometrical abnormality in general and the ineffective esophageal motility in particular and the esophageal or gastroesophageal reflux disease symptoms, the abnormal reflux, the disease seriousness, the ascites presence and the gauge of the varices. The majority of cirrhotic patients with non-treated esophageal varices present esophageal motor disorders. No predictive factor was found. The clinical relevance of these findings need more researches in the scope to define the real meaning of theses abnormalities.

    Patients with cirrhosis with acute variceal bleeding (AVB) have high mortality rates (15%-20%). Previously described models are seldom used to determine prognoses of these patients, partially because they have not been validated externally and because they include subjective variables, such as bleeding during endoscopy and Child-Pugh score, which are evaluated inconsistently. We aimed to improve determination of risk for patients with AVB. We analyzed data collected from 178 patients with cirrhosis (Child-Pugh scores of A, B, and C: 15%, 57%, and 28%, respectively) and esophageal AVB who received standard therapy from 2007 through 2010. We tested the performance (discrimination and calibration) of previously described models, including the model for end-stage liver disease (MELD), and developed a new MELD calibration to predict the mortality of patients within 6 weeks of presentation with AVB. MELD-based predictions were validated in cohorts of patients from Canada (n = 240) and Spain (n = 221). Among study subjects, the 6-week mortality rate was 16%. MELD was the best model in terms of discrimination; it was recalibrated to predict the 6-week mortality rate with logistic regression (logit, -5.312 + 0.207 • MELD; bootstrapped R(2), 0.3295). MELD values of 19 or greater predicted 20% or greater mortality, whereas MELD scores less than 11 predicted less than 5% mortality. The model performed well for patients from Canada at all risk levels. In the Spanish validation set, in which all patients were treated with banding ligation, MELD predictions were accurate up to the 20% risk threshold. We developed a MELD-based model that accurately predicts mortality among patients with AVB, based on objective variables available at admission. This model could be useful to evaluate the efficacy of new therapies and stratify patients in randomized trials. Copyright © 2014 AGA Institute. Published by Elsevier Inc. All rights reserved.

    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.

    EIT has been proposed for acute stroke differentiation, specifically to determine the type of stroke, either ischaemia (clot) or haemorrhage (bleed) to allow the rapid use of clot-busting drugs in the former (Romsauerova et al 2006) . This addresses an important medical need, although there is little treatment offered in the case of haemorrhage. Also the demands on EIT are high with usually no availability to take a 'before' measurement, ruling out time difference imaging. Recently a new treatment option for haemorrhage has been proposed and is being studied in international randomised controlled trial: the early reduction of elevated blood pressure to attenuate the haematoma. This has been shown via CT to reduce bleeds by up to 1mL by Anderson et al 2008. The use of EIT as a continuous measure is desirable here to monitor the effect of blood pressure reduction. A 1mL increase of haemorrhagic lesion located near scalp on the right side of head caused a boundary voltage change of less than 0.05% at 50 kHz. This could be visually observed in a time difference 3D reconstruction with no change in electrode positions, mesh, background conductivity or drift when baseline noise was less than 0.005% but not when noise was increased to 0.01%. This useful result informs us that the EIT system must have noise of less than 0.005% at 50 kHz including instrumentation, physiological and other biases.

    Current management of late post-pancreatectomy haemorrhage in a university hospital. Haemorrhage after pancreaticoduodenectomy is a serious complication. We report on risk factors and outcome following management by radiological intervention. Tertiary care centre in Scotland. Sixty-seven consecutive patients who underwent pancreaticoduodenectomy. All pancreaticoduodenectomies over a 3-year period were reviewed. International Study Group on Pancreatic Surgery (ISGPS) definition of post-pancreatectomy haemorrhage was used. Endpoints were incidence of haemorrhage, pancreaticojejunal anastomosis leak, methicillin-resistant Staphylococcus aureus (MRSA) infection and mortality. Seven patients (10.4%) developed post-pancreatectomy haemorrhage out of 67 pancreaticoduodenectomies. Median age was 71 years. All post-pancreatectomy haemorrhage were late onset (median 23 days; range: 3-35 days), extraluminal and ISGPS grade C. Post-pancreatectomy haemorrhage arose from hepatic artery (n=4), superior mesenteric artery (n=1), jejunal artery (n=1), and splenic artery (n=1). Angiographic treatment was successful in all patients by embolisation (n=5) or stent grafting (n=2). Pancreatic fistula rate was similar in post-pancreatectomy haemorrhage and "no-haemorrhage" groups (57.1% vs. 40.0%; P=0.440); MRSA infection was significantly higher in post-pancreatectomy haemorrhage group (57.1% vs. 16.7%; P=0.030). Mortality from post-pancreatectomy haemorrhage despite successful haemostasis was 42.9%. Univariate and multivariate analysis identified MRSA infection as a risk factor for post-pancreatectomy haemorrhage. CT angiogram followed by conventional catheter angiography is effective for treatment of late extraluminal post-pancreatectomy haemorrhage. MRSA infection in the abdominal drain fluid increases its risk and therefore aggressive treatment of MRSA and high index of suspicion are indicated.

    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.

    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

    Gastric varices (GV) have higher rates of morbidity and mortality from hemorrhage than esophageal varices. Several studies have shown the safety and efficacy of cyanoacrylate (CA) injection for acute gastric variceal hemorrhage. We report data from our experience with CA injection for GV before and after routine use of post-injection audible Doppler assessment (ADA) for GV obturation and describe long-term outcomes after this therapy. We retrospectively identified patients who had documented GV, underwent CA injection, and had at least 2 weeks of follow-up. We recorded and analyzed the survival and rebleeding rates with patient demographics, clinical data, and endoscopy findings between two groups of patients who were categorized by CA injection prior to and after inception of the ADA technique. Seventy-one patients were identified with 16 patients analyzed in a group where ADA was not used (Pre-ADA) and 55 analyzed where ADA was used (Post-ADA). No rebleeding events were observed within 1 week of initial CA injection. No embolic events were reported after any initial CA injection within 4 weeks. The rate of bleed-free survival at 1 year was 69.6% in the Pre-ADA group and 85.8% in the Post-ADA without statistical significance. The all-cause 1-year mortality was 13.8% in the Pre-ADA group and 10.7% in the Post-ADA group without statistical significance. ADA of CA-injected GV does not appear to significantly affect adverse events or clinical outcomes; however, our findings are limited by small sample size and cohort proportions allowing for significant type II statistical error. Further prospective investigation is required to determine the impact of ADA on clinical outcomes after GV obturation.

    To evaluate the efficacy of proton pump inhibitors (PPIs) in reducing rebleeding and bleeding-related death rates after endoscopic gastric variceal obliteration (GVO) using N-butyl-2-cyanoacrylate (NBC). This study enrolled 341 patients who were consecutively diagnosed with and treated for bleeding gastric varices. The patients were divided into PPI and non-PPI groups, and their endoscopic findings, initial hemostasis outcomes, rebleeding and bleeding-related death rates, and treatment-related complications were analyzed. The rate of initial hemostasis was 97.1%. rebleeding occurred in 2.2% of patients within 2 weeks, 3.9% of patients within 4 weeks, 18.9% of patients within 6 months, and 27.6% of patients within 12 months of the GVO procedure. A previous history of variceal bleeding (relative risk [RR], 1.955; 95% confidence interval [CI], 1.263 to 3.028; p = 0.003) and use of PPIs (RR, 0.554; 95% CI, 0.352 to 0.873; p = 0.011) were associated with rebleeding. Child-Pugh class C (RR, 10.914; 95% CI, 4.032 to 29.541; p < 0.001), failure of initial hemostasis (RR, 13.329; 95% CI, 2.795 to 63.556; p = 0.001), and the presence of red-colored concomitant esophageal varices (RR, 4.096; 95% CI, 1.320 to 12.713; p = 0.015) were associated with bleeding-related death. The prophylactic use of PPIs reduces rebleeding after GVO using NBC in patients with gastric variceal hemorrhage. However, prophylactic use of PPIs does not reduce bleeding-related death.

    Purpose To determine the diagnostic performance of magnetic resonance (MR) elastography in comparison to spleen length and dynamic contrast material–enhanced (DCE) MR imaging in association with esophageal varices in patients with liver cirrhosis by using endoscopy as the reference standard. Materials and Methods This retrospective study received institutional review board approval, and informed consent was waived. One hundred thirty-nine patients with liver cirrhosis who underwent liver DCE MR imaging, including MR elastography, were included. Hepatic stiffness (HS) and spleen stiffness (SS) values assessed with MR elastography, as well as spleen length, were correlated with the presence of esophageal varices and high-risk varices by using Spearman correlation analysis. The diagnostic performance of MR elastography was compared with that of DCE MR imaging and combined assessment of MR elastography and DCE MR imaging by using receiver operating characteristic analysis. MR elastography reproducibility was assessed prospectively, with informed consent, in another 15 patients by using intraclass correlation coefficients. Results There were significant positive linear correlations between HS, SS, and spleen length and the grade of esophageal varices (r = 0.46, r = 0.48, and r = 0.36, respectively; all P < .0001). HS and SS values (>4.81 kPa and >7.60 kPa, respectively) showed better performance than did spleen length in the association with esophageal varices (P = .0306 and P = .0064, respectively). Diagnostic performance of HS and SS in predicting high-risk varices was comparable to that of DCE MR imaging (P = .1282 and P = .1371, respectively). When MR elastography and DCE MR imaging were combined, sensitivity improved significantly (P = .0004). MR elastography was highly reproducible (intraclass correlation coefficient > 0.9). Conclusion HS and SS are associated with esophageal varices and showed better performance than did spleen length in assessing the presence

    Aspirin is of moderate overall benefit for patients with acute disabling ischemic stroke. It is unclear whether functional outcome could be improved after stroke by targeting aspirin to patients with a high risk of recurrent thrombosis or a low risk of haemorrhage. We aimed to determine whether patients at higher risk of thrombotic events or poor functional outcome, or lower risk of major haemorrhage had a greater absolute risk reduction of poor functional outcome with aspirin than the average patient. We used data on individual ischemic stroke patients from three large trials of aspirin vs. placebo in acute ischemic stroke: the first International Stroke Trial (n = 18,372), the Chinese Acute Stroke Trial (n = 20,172) and the Multicentre Acute Stroke Trial (n = 622). We developed and evaluated clinical prediction models for the following: early thrombotic events (myocardial infarction, ischemic stroke, deep vein thrombosis and pulmonary embolism); early haemorrhagic events (significant intracranial haemorrhage, major extracranial haemorrhage, or haemorrhagic transformation of an infarct); and late poor functional outcome. We calculated the absolute risk reduction of poor functional outcome (death or dependence) at final follow-up in: quartiles of early thrombotic risk; quartiles of early haemorrhagic risk; and deciles of poor functional outcome risk. Ischemic stroke patients who were older, had lower blood pressure, computerized tomography evidence of infarct or more severe deficits due to stroke had increased risk of thrombotic and haemorrhagic events and poor functional outcome. Prediction models built with all baseline variables (including onset to treatment time) discriminated weakly between patients with and without recurrent thrombotic events (area under the receiver operating characteristic curve 0·56, 95% CI:0·53-0·59) and haemorrhagic events (0·57, 0·52-0·64), though well between patients with and without poor functional outcome (0·77, 0

    Isolated gastric varices (IGV) have a lower risk of bleeding than esophageal varices, however IGV bleeding is associated with a higher mortality than bleeding of esophageal varices. In recent years, two widely used treatments for IGV have been balloon-occluded retrograde transvenous obliteration (B-RTO) and endoscopic injection sclerotherapy (EIS) using cyanoacrylate or ethanolamine oleate (EO). This study compared these two treatment methods for IGV. The subjects were 112 patients who were treated at our hospital for IGV bleeding between October 1990 and December 2003. Forty-nine (49) patients were treated with B-RTO and 63 patients with EIS. These two patient groups were compared as regards content of treatment, post-treatment incidence of variceal bleeding, incidence of IGV rebleeding, survival rate, cause of death, and complications. Multivariate analysis was performed on post-treatment variceal bleeding and survival. Although EO was used in higher amounts in the B-RTO group than in the EIS group, the B-RTO group had a significantly lower number of treatment sessions and a significantly shorter treatment period (p<0.05). The EIS group had significantly more patients with IGV rebleeding after treatment than the B-RTO group. Treatment method was the only independent prognostic factor of IGV bleeding after treatment (p=0.024). The two groups did not differ significantly in the percentage of patients with aggravated esophageal varices after treatment. Bleeding from ectopic varices was not observed in any patient. There was no significant difference in survival by treatment method. The presence of hepatocellular carcinoma was the only independent prognostic factor for survival (p=0.003). It is concluded that B-RTO was more effective than EIS in the eradication of IGV and prevention of IGV recurrence and rebleeding.

    Cerebral microbleeds are a potential neuroimaging biomarker of cerebral small vessel diseases that are prone to intracranial bleeding. We aimed to determine whether presence of cerebral microbleeds can identify patients at high risk of symptomatic intracranial haemorrhage when anticoagulated for atrial fibrillation after recent ischaemic stroke or transient ischaemic attack. Our observational, multicentre, prospective inception cohort study recruited adults aged 18 years or older from 79 hospitals in the UK and one in the Netherlands with atrial fibrillation and recent acute ischaemic stroke or transient ischaemic attack, treated with a vitamin K antagonist or direct oral anticoagulant, and followed up for 24 months using general practitioner and patient postal questionnaires, telephone interviews, hospital visits, and National Health Service digital data on hospital admissions or death. We excluded patients if they could not undergo MRI, had a definite contraindication to anticoagulation, or had previously received therapeutic anticoagulation. The primary outcome was symptomatic intracranial haemorrhage occurring at any time before the final follow-up at 24 months. The log-rank test was used to compare rates of intracranial haemorrhage between those with and without cerebral microbleeds. We developed two prediction models using Cox regression: first, including all predictors associated with intracranial haemorrhage at the 20% level in univariable analysis; and second, including cerebral microbleed presence and HAS-BLED score. We then compared these with the HAS-BLED score alone. This study is registered with ClinicalTrials.gov, number NCT02513316. Between Aug 4, 2011, and July 31, 2015, we recruited 1490 participants of whom follow-up data were available for 1447 (97%), over a mean period of 850 days (SD 373; 3366 patient-years). The symptomatic intracranial haemorrhage rate in patients with cerebral microbleeds was 9·8 per 1000 patient-years (95% CI 4·0-20·3

    The 2015 Baveno VI guidelines recommend against performing upper gastrointestinal endoscopy in patients with compensated cirrhosis who have a liver stiffness <20 kPa and a platelet count >150 000/mm³ because of a low prevalence of varices at risk of bleeding in this population. The aim was to synthesize the available evidence on the usefulness of the combined use of liver stiffness and platelet count to identify patients without oesophageal varices. Meta-analysis of trials evaluating the usefulness of a given cut-off for liver stiffness and platelet count to rule out the presence of oesophageal varices. Fifteen studies were included. All studies excepting five used the Baveno VI criteria. Compared to patients with either high liver stiffness or low platelet count, those with low liver stiffness and normal platelet count had a lower risk of varices at risk of bleeding (OR=0.22, 95% CI=0.13-0.39, P<.001) with low heterogeneity between studies (I 2 =21%). They also had a lower risk of varices (OR=0.23, 95% CI=0.17-0.32, P<.001) with moderate heterogeneity between studies (I 2 =28%). In patients with low liver stiffness and normal platelet count, the pooled estimate rates for varices at risk of bleeding was 0.040 (95% CI=0.027-0.059) with low heterogeneity between studies (I 2 =3%). Patients with low liver stiffness and normal platelet count have a lower risk of varices than those with either high liver stiffness or low platelet count. Varices at risk of bleeding are found in no more than 4% of patients when liver stiffness is <20 kPa and platelet count is normal. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    To ensure good outcomes in the management of subarachnoid haemorrhage (SAH), accurate prediction is crucial for initial assessment of patients presenting with acute headache. We conducted this study to develop a new clinical decision rule using only objectively measurable predictors to exclude SAH, offering higher specificity than the previous Ottawa SAH Rule while maintaining comparable sensitivity. Multicentre prospective cohort study. Tertiary-care emergency departments of five general hospitals in Japan from April 2011 to March 2014. Eligible patients comprised 1781 patients aged >15 years with acute headache, excluding trauma or toxic causes and patients who presented in an unconscious state. Definitive diagnosis of SAH was based on confirmation of SAH on head CT or lumbar puncture findings of non-traumatic red blood cells or xanthochromia. A total of 1561 patients were enrolled in this study, of whom 277 showed SAH. Using these enrolled patients, we reached a rule with mainly categorical predictors used in previous reports, called the 'Ottawa-like rule', offering 100% sensitivity when using any of age ≥40 years, neck pain or stiffness, altered level of consciousness or onset during exertion. Using the 1317 patients from whom blood samples were obtained, a new rule using any of systolic blood pressure >150 mm Hg, diastolic blood pressure >90 mm Hg, blood sugar >115 mg/dL or serum potassium <3.9 mEq/L offered 100% sensitivity (95% CI 98.6% to 100%) and 14.5% specificity (12.5% to 16.9%), while the Ottawa-like rule showed the same sensitivity with a lower specificity of 8.8% (7.2% to 10.7%). While maintaining equal sensitivity, our new rule seemed to offer higher specificity than the previous rules proposed by the Ottawa group. Despite the need for blood sampling, this method can reduce unnecessary head CT in patients with acute headache. UMIN 00004871. Published by the BMJ Publishing Group Limited.

    A 75-year old man had been diagnosed at 42 years of age as having polycythemia vera and had been monitored at another hospital. Progression of anemia had been recognized at about age 70, and the patient was thus referred to our center in 2008 where secondary myelofibrosis was diagnosed based on bone marrow biopsy findings. Hematemesis due to rupture of esophageal varices occurred in January and February of 2011. The bleeding was stopped by endoscopic variceal ligation. Furthermore, in March of the same year, hematemesis recurred and the patient was transported to our center. He was in irreversible hemorrhagic shock and died. The autopsy showed severe bone marrow fibrosis with mainly argyrophilic fibers, an observation consistent with myelofibrosis. The liver weighed 1856 g the spleen 1572 g, indicating marked hepatosplenomegaly. The liver and spleen both showed extramedullary hemopoiesis. Myelofibrosis is often complicated by portal hypertension and is occasionally associated with gastrointestinal hemorrhage due to esophageal varices. A patient diagnosed as having myelofibrosis needs to be screened for esophageal/gastric varices. Myelofibrosis has a poor prognosis. Therefore, it is necessary to carefully decide the therapeutic strategy in consideration of the patient’s concomitant conditions, treatment invasiveness and quality of life. PMID:22851873

    The management of parastomal varices is not established. Transjugular intrahepatic portosystemic shunt (TIPS) creation is the most commonly described treatment; however, the rebleed rate after TIPS is 21-37%. The purpose of the study is to determine the effectiveness of transvenous obliteration using sodium tetradecyl sulfate (STS) and to describe a new simplified technique in obliterating these varices. Four patients are presented who underwent transvenous obliteration using STS. One was obliterated using balloon occlusion from the systemic veins, the second was obliterated without balloon from a transhepatic antegrade approach, and the last two patients were obliterated using the direct antegrade technique. This simplified technique requires only a micropuncture kit (not requiring balloons or coils) and ultrasound transducer compression of the systemic draining veins, relying on high portal pressure to keep the sclerosant confined to the varices. The sclerosant is essentially trapped between the portal pressure and the ultrasound-transducer compression (10-15 min). Technical success was achieved in all four patients without procedural or postprocedural complications and no rebleeding for a mean follow-up of 17 (range 2-33) months. Transvenous obliteration of parastomal varices utilizing STS as a sclerosant is safe and effective. The newly described technique is simple, feasible, and requires minimal equipment (no balloons or coils or catheters).

    Cervico-Mediastinal Lymphangiomas (CML) are caused by atresia of the efferent lymphatics or lack of communication between lymphatics and venous channels. Cervico-Mediastinal Lymphangiomas in certain cases require emergency surgery to secure decompression of the airways. The purpose of this study is to present a multidisciplinary surgical approach in the treatment of urgently complicated Cervico-Mediastinal Lymphangiomas, and to asses the surgical tactics and satisfactory outcome after a two-stage operation. The paper presents a case of a 48-day-old girl with acute haemorrhage of Cervico-Mediastinal Lymphangioma, resulting from an increased arterial blood pressure due to thrombosis of the internal jugular vein. This condition required the convening of an emergency multidisciplinary surgical team which resolved emergency decompression by removal of the cervical tumour component. The authors discuss the reasons for the emergency indications for operation in this case, the dynamics in multi-stage treatment, the regression of the mediastinal component resulting from the developed inflammation, the intraoperative difficulties and functional complications resulting from the strife after radicalism. The presented case shows indications for emergency surgical intervention in acute growing CML. It illustrates the need for a multidisciplinary surgical approach involving a team of experts in paediatric, vascular, cardiac and aesthetic surgery.

    Systemic embolism is an unusual complication of endoscopic obturation of gastroesophageal varices with glue. This report describes a case of cerebral embolism after this procedure. Intracardiac glue within the left atrium was demonstrated by echocardiography. Cardiac fluoroscopy demonstrated an abnormal vessel connecting periesophageal veins with the right upper pulmonary vein. Cardiac surgery was performed. Intracardiac glue was removed and the entering orifice of the abnormal vessel in the right upper pulmonary vein was sutured. To our knowledge, this is the first reported case of intracardiac glue after variceal obturation. Echocardiography is useful in the diagnosis of this rare complication.

    we aimed to investigate the accuracy of liver (LSM) spleen stiffness measurement (SSM) with transient elastography (TE) to predict varices in the presence of non-selective beta-blockers (NSBB). In this cross-sectional study of consecutive patients with chronic hepatitis B (CHB) and cirrhosis, all patients underwent TE and upper endoscopic examinations. LSM and SSM in predicting varices in patients receiving and not receiving NSBB were evaluated. Altogether 144 CHB patients (29 receiving NSBB; 35 with any varices, 31 and 11 with esophageal and gastric varices, respectively) were recruited. Their mean LSM and SSM were 13.3 ± 9.0 kPa and 32.8 ± 19.2 kPa, respectively. The correlation between LSM and SSM was better in the NSBB subgroup (r = 0.525, P = 0.003) than its counterpart (r = 0.329, P  < 0.001). The area under receiver operating characteristic curve (AUROC) of LSM and SSM for any varices was 0.675 and 0.685 (P = 0.002 and 0.001), respectively. SSM of 18.9 kPa had a negative predictive value of 92.1% and negative likelihood ratio of 0.27 for ruling out any varices; and SSM of 54.9 kPa had a positive predictive value of 56.5% and a positive likelihood ratio of 4.05 to rule in varices. The AUROC of LSM for varices was 0.742 and 0.549 in patients with or without NSBB, respectively; the corresponding AUROC of SSM was 0.572 and 0.603, respectively. SSM only has modest accuracy to predict varices independent of NSBB use. An SSM cutoff value of 18.9 kPa may be adopted to achieve a high negative predictive value to rule out varices. © 2016 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.

    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.

    Acute esophageal variceal hemorrhage is a dreaded complication of portal hypertension. Its management has evolved rapidly in recent years. Endoscopic therapy is often employed to arrest bleeding varices as well as to prevent early rebleeding. The combination of vasoconstrictor and endoscopic therapy is superior to vasoconstrictor or endoscopic therapy alone for control of acute esophageal variceal hemorrhage. After control of acute variceal bleeding, combination of banding ligation and beta-blockers is generally recommended to prevent variceal rebleeding. To prevent the catastrophic event of acute variceal bleeding, endoscopic banding ligation is an important tool in the prophylaxis of first bleeding. Endoscopic obturation with cyanoacrylate is usually utilized to arrest acute gastric variceal hemorrhage as well as to prevent rebleeding. It can be concluded that endoscopic therapies play a pivotal role in management of portal hypertensive bleeding.

    The hemodynamic response to ss-blockers alone or with nitrates is highly predictive of efficacy in prevention of variceal bleeding. Hemodynamic monitoring (HDM) requires catheterization of the hepatic vein and measurement of the hepatic venous pressure gradient, the difference between wedged and free hepatic venous pressure. The aim of this study was to compare HDM with no HDM in patients considered for primary pharmacoprophylaxis of esophageal variceal bleeding. A decision model was constructed to compare HDM with no HDM in cirrhotic patients with moderate to large esophageal varices. Patients intolerant to beta-blocker therapy would undergo endoscopic variceal ligation; those with an inadequate hemodynamic response (HDR) to beta-blocker therapy could have nitrates added before ligation was considered. Variceal bleeding was treated with ligation, with transjugular intrahepatic portosystemic shunt (TIPS) reserved for refractory bleeding. Probabilities of treatment responses as well as risks of bleeding and mortality were based on published literature. Only direct costs were considered during the 5-yr time horizon. Outcomes were cost in United States dollars, survival length in life-years, and proportions of patients who experienced variceal bleeding, TIPS insertion, and mortality from any cause. In the base case analysis, HDM was either cost-saving ($2,523 US dollars /life-year gained) or cost-effective (incremental cost-effectiveness ratio of $5,200 US dollars/life-year saved) compared with no HDM, depending on whether nitrates were added to beta-blocker therapy. HDM reduced variceal bleeding by nearly 60% and had a small effect on all-cause mortality. In the sensitivity analysis, HDM was sensitive to the time horizon, as it was not cost-effective for a time horizon of <22 months and was not cost-saving before 49 months. The cost-effectiveness of HDM was not sensitive to reasonable variation in the probability of HDR to beta-blocker therapy, risk of bleeding, risk

    Current guidelines recommend upper endoscopic screening for patients with hepatic cirrhosis and primary prophylaxis with a nonselective beta-blocker for those with large varices. However, only 25% of cirrhotics develop large varices. Thus, the aim of this study is to evaluate the most cost-effective approach for primary prophylaxis of variceal hemorrhage. Using a Markov model, we compared the costs and clinical outcomes of three strategies for primary prophylaxis of variceal bleeding. In the first strategy, patients were given a beta-blocker without undergoing upper endoscopy. In the second strategy, patients underwent upper endoscopic screening; those found to have large varices were treated with a beta-blocker. In the third strategy, no prophylaxis was used. Selected sensitivity analyses were performed to validate outcomes. Our results show screening prophylaxis was associated with a cost of $37,300 and 5.72 quality-adjusted life yr (QALYs). Universal prophylaxis was associated with a cost of $34,100 and 6.65 QALYs. The no prophylaxis strategy was associated with a cost of $36,600 and 4.84 QALYs. The incremental cost-effectiveness ratio was $800/QALY for the endoscopic strategy relative to the no prophylaxis strategy. Screening endoscopy was cost saving when the compliance, bleed risk without beta-blocker, and variceal bleed costs were increased, and when the discount rate, bleed risk on beta-blockers, and cost of upper endoscopy were decreased. In contrast, the universal prophylaxis strategy was persistently cost saving relative to the no prophylaxis strategy. In comparing the strategies, sensitivity analysis on the death rates from variceal hemorrhage did not alter outcomes. Our results provide economic and clinical support for primary prophylaxis of esophageal variceal bleeding in patients with hepatic cirrhosis. Universal prophylaxis with beta-blocker is preferred because it is consistently associated with the lowest costs and highest QALYs.

    The Ebola virus is a highly virulent, single-stranded ribonucleic acid virus which affects both humans and apes and has fast become one of the world’s most feared pathogens. The virus induces acute fever and death, with haemorrhagic syndrome occurring in up to 90% of patients. The known species within the genus Ebolavirus are Bundibugyo, Sudan, Zaïre, Reston and Taï Forest. Although endemic in Africa, Ebola has caused worldwide anxiety due to media hype and concerns about its international spread, including through bioterrorism. The high fatality rate is attributed to unavailability of a standard treatment regimen or vaccine. The disease is frightening since it is characterised by rapid immune suppression and systemic inflammatory response, causing multi-organ and system failure, shock and often death. Currently, disease management is largely supportive, with containment efforts geared towards mitigating the spread of the virus. This review describes the classification, morphology, infective process, natural ecology, transmission, epidemic patterns, diagnosis, clinical features and immunology of Ebola, including management and epidemic containment strategies.

    The incidence of aspirin ingestion during the week preceding overt gastroduodenal bleeding was recorded in 582 patients. A positive aspirin history was found in 80% of patients with acute gastric lesions, in 63% of those in whom no lesion was found, in 52% of those with a chronic duodenal ulcer, and in 49% of patients with a chronic gastric ulcer. In a control series of 542 consecutive patients without overt bleeding admitted to the same wards during part of the time of this investigation the aspirin incidence was 32%. The difference in aspirin habits between these two series confirms that aspirin is a factor in precipitating overt haemorrhage in acute and chronic peptic ulcers, and that it is an important cause of bleeding from the stomach or duodenum, or both, in the absence of a chronic peptic ulcer.

    A non cirrhotic patient with esophageal varices and portal vein thrombosis had recurrent variceal bleeding unsuccessfully controlled by endoscopy and esophageal transection. Emergency transhepatic portography confirmed the thrombosed right branch of the portal vein, while the left branch appeared angulated, shifted and stenotic. A stent was successfully implanted into the left branch and the collateral vessels along the epatoduodenal ligament disappeared. In patients with esophageal variceal hemorrhage and portal thrombosis if endoscopy fails, emergency esophageal transection or nonselective portocaval shunting are indicated. The rare patients with only partial portal thrombosis can be treated directly with stenting through an angioradiologic approach. PMID:18644135

    Metal artefacts can impair accurate diagnosis of haemorrhage using flat detector CT (FD-CT), especially after aneurysm coiling. Within this work we evaluate a prototype metal artefact reduction algorithm by comparison of the artefact-reduced and the non-artefact-reduced FD-CT images to pre-treatment FD-CT and multi-slice CT images. Twenty-five patients with acute aneurysmal subarachnoid haemorrhage (SAH) were selected retrospectively. FD-CT and multi-slice CT before endovascular treatment as well as FD-CT data sets after treatment were available for all patients. The algorithm was applied to post-treatment FD-CT. The effect of the algorithm was evaluated utilizing the pre-post concordance of a modified Fisher score, a subjective image quality assessment, the range of the Hounsfield units within three ROIs, and the pre-post slice-wise Pearson correlation. The pre-post concordance of the modified Fisher score, the subjective image quality, and the pre-post correlation of the ranges of the Hounsfield units were significantly higher for artefact-reduced than for non-artefact-reduced images. Within the metal-affected slices, the pre-post slice-wise Pearson correlation coefficient was higher for artefact-reduced than for non-artefact-reduced images. The overall diagnostic quality of the artefact-reduced images was improved and reached the level of the pre-interventional FD-CT images. The metal-unaffected parts of the image were not modified. • After coiling subarachnoid haemorrhage, metal artefacts seriously reduce FD-CT image quality. • This new metal artefact reduction algorithm is feasible for flat-detector CT. • After coiling, MAR is necessary for diagnostic quality of affected slices. • Slice-wise Pearson correlation is introduced to evaluate improvement of MAR in future studies. • Metal-unaffected parts of image are not modified by this MAR algorithm.

    Introduction Haemorrhagic stroke is of significant healthcare concern due to its association with high mortality and lasting impact on the survivors’ quality of life. Treatment decisions and clinical outcomes depend strongly on the size, spread and location of the haematoma. Non-contrast CT (NCCT) is the primary neuroimaging modality for haematoma assessment in haemorrhagic stroke diagnosis. Current procedures do not allow convenient NCCT-based haemorrhage volume calculation in clinical settings, while research-based approaches are yet to be tested for clinical utility; there is a demonstrated need for developing effective solutions. The project under review investigates the development of an automatic NCCT-based haematoma computation tool in support of accurate quantification of haematoma volumes. Methods and analysis Several existing research methods for haematoma volume estimation are studied. Selected methods are tested using NCCT images of patients diagnosed with acute haemorrhagic stroke. For inter-rater and intrarater reliability evaluation, different raters will analyse haemorrhage volumes independently. The efficiency with respect to time of haematoma volume assessments will be examined to compare with the results from routine clinical evaluations and planimetry assessment that are known to be more accurate. The project will target the development of an enhanced solution by adapting existing methods and integrating machine learning algorithms. NCCT-based information of brain haemorrhage (eg, size, volume, location) and other relevant information (eg, age, sex, risk factor, comorbidities) will be used in relation to clinical outcomes with future project development. Validity and reliability of the solution will be examined for potential clinical utility. Ethics and dissemination The project including procedures for deidentification of NCCT data has been ethically approved. The study involves secondary use of existing data and does not require new consent

    Laparoscopic gastric devascularization(Lap GDS) and splenectomy (SPL) for gastric varices is technically challenging because of highly developed collateral vessels and bleeding tendency. We investigated the feasibility of customization of Lap GDS and SPL based on CT vascular anatomy. We analyzed 61 cirrhotic patients with gastric varices who underwent Lap GDS and SPL between 2006 and 2014. Lap GDS was customized according to the afferent feeding veins (left gastric vein (LGV) and/or posterior gastric vein (PGV)/short gastric vein (SGV)) and efferent drainage veins (gastrorenal shunt and/or gastrophrenic shunt, or numerous retroperitoneal veins) based on CT imaging. Thirty-four patients with efferent drainage veins suitable for balloon-occluded retrograde transvenous obliteration (B-RTO) underwent B-RTO instead of surgical GDS, with subsequent Lap SPL. Among 27 patients with gastric varices unsuitable for B-RTO, 15 patients with PGV/SGV underwent Lap GDS of the greater curvature and SPL, and 12 patients with LGV or LGV/PGV/SGV underwent Lap GDS of the greater and lesser curvature and SPL. The mean operation time was 294 min and mean blood loss was 198 g. There was no mortality or severe morbidity. Gastric varices were eradicated in all 61 patients, with no bleeding or recurrence during a mean follow-up of 55.9 months. The cumulative 3-, 5-, and 7-year survival rates were 92, 82, and 64%, respectively. Lap GDS and SPL customized based on CT vascular anatomy is a safe and effective procedure for treating gastric varices.

A prospective randomized trial. Department of Gastroenterology and Hepatology, Sheikh Zayed Hospital, Lahore, from November 2003 to July 2005. One hundred and sixty cirrhotic patients with esophageal variceal bleeding were randomized to four treatment groups (propranolol, propranolol plus isosorbide mononitrate, band ligation, band ligation plus propranolol and nitrate) with 40 patients in each group. Patients were followed for 6 months after the enrolment of last patient. Primary end points were recurrence of esophageal variceal bleeding and death. Treatment complications were noted. Four treatment groups were comparable regarding baseline characteristics. Esophageal variceal rebleeding occurred in 22% patients in band ligation plus drugs group, 26% patients in drug combination group, 31% patients in banding group and 38% patients in propranolol group (p=0.41). Difference in mortality rates was also not significant. There was no significant difference between treatment groups in prevention of esophageal variceal rebleeding.

    Systemic lupus erythematosus (SLE) is an autoimmune disease that affects many organs, but multisystem dysfunction is rare. Here, we report a case of a 29-year-old woman who was initially diagnosed with SLE complications including lupus nephritis, lupus encephalopathy, renal hypertension, thrombocytopenia, anaemia and hyperkalaemia. She recovered following treatment with high dose methylprednisolone, intravenous immunoglobulin (IVIG) and continuous renal replacement therapy (CRRT). However, a few days after hospital discharge, she developed gastrointestinal bleeding. Although intensive treatment was administered, the patient deteriorated rapidly and had a progressive decline in oxygen saturation followed by diffuse alveolar haemorrhage and acute left heart failure. Inotropic therapy, mechanical ventilation, blood transfusion, CRRT, antibiotics, intravenous glucocorticoids and other support therapies were initiated and gradually the patient's vital signs stabilized and haemoptysis subsided. This case report emphasises that complications of SLE can occur at any stage of the disease, especially in patients with active SLE. Therefore, it is important for clinicians to be aware of the rare presentations of SLE and its complex management. For multisystem dysfunction, early intensive treatment with high dose corticosteroids and cyclophosphamide is advocated.

    To assess the efficacy of transjugular intrahepatic portosystemic shunt (TIPS) creation with or without variceal coil and/or plug embolization in decompressing or occluding gastric varices (GVs). In this retrospective study, 78 patients with GV bleeding who underwent TIPS creation with or without embolotherapy with metallic coils and/or plugs from 1999 to 2014 were identified. Individuals who had a bare-metal TIPS and/or lacked post-TIPS imaging or endoscopic follow-up were excluded. The final cohort included 26 patients (16 men; median age, 54 y; median Model for End-stage Liver Disease score, 16). Variceal types, supplying vessels, and postprocedure GV patency on cross-sectional imaging or endoscopy were assessed. The primary study outcome measure was GV patency rate as a surrogate for efficacy of TIPS creation with or without embolization. GVs included gastroesophageal varix types 1 (n = 10) and 2 (n = 2), isolated GV types 1 (n = 4) and 2 (n = 2), and unspecified (n = 8). TIPS creation resulted in a median final portosystemic pressure gradient of 7 mm Hg. Multiple GV-supplying vessels (left/posterior/short gastric veins) were present in 65% of patients (n = 17). Embolization was performed in 69% (n = 18). Thirteen, four, and nine patients had imaging, endoscopic, or both imaging/endoscopic follow-up. GV patency rate was 65% (n = 17; 61%/75% with/without embolization) at a median of 128.5 days (range, 1-1,295 d) after TIPS creation. Incidence of recurrent bleeding was 27% (n = 7), and the 90-day mortality rate was 15% (n = 4). In this study, most GVs showed persistent patency despite TIPS decompression and variceal embolization, and the incidence of recurrent bleeding was high. The findings suggest suboptimal efficacy for GVs, and indicate a need for study of alternative or adjunctive approaches to GV treatment, such as chemical obliteration. Copyright © 2016 SIR.

    Background and study aims  Screening for esophageal and gastric varices is indicated for patients with portal hypertension or cirrhosis. Typically, conventional endoscopy is used; however, the need for sedation increases the costs and risks, especially in cirrhotic patients. Use of transnasal endoscopy with an ultrathin endoscope enables study of the upper gastrointestinal tract without the need for sedation. The objective of this study is to evaluate the feasibility of transnasal endoscopy in screening for esophageal and gastric varices in patients with chronic liver disease. Patients and methods  This was a prospective study in which transnasal endoscopy was carried out in patients with cirrhosis or portal hypertension who had indications for screening of esophageal and gastric varices. The following variables were evaluated: demographical data, duration of procedure, patient tolerance and acceptance, adverse events (AEs), endoscopic findings and interobserver agreement related to portal hypertension alterations ( kappa index). Results  A total of 50 patients entered the study. The most common cause of liver disease was chronic viral hepatitis (66 %). Among the cirrhotic patients, most of the patients were Child-Pugh A (74 %). In 5 patients (10 %), nasal intubation was not possible. Two patients (4 %) experienced minor epistaxis. Tolerance was excellent or good in 92 % according with a visual analogic scale. In 16 patients (32 %), esophageal varices were detected and in 2 patients (4 %) gastric varices were detected. The mean duration of the procedure was 7 minutes. Conclusions  Transnasal endoscopy is feasible, effective and well tolerated for screening of esophageal and gastric varices in patients with chronic liver disease. It can be performed in outpatient clinics safely and without the use of sedation. PMID:28691048

    Two hundred patients affected by liver cirrhosis and oesophageal varices were studied in 9 Gastrointestinal Units in Lombardy (Northern Italy) in order to assess factors possibly related to variceal bleeding. Only patients without any previous episode of gastrointestinal bleeding were included in the prospective evaluation. For each patient demographic data, aetiology of cirrhosis, various clinical and biochemical parameters able to group patients into the three Child-Pugh Classes, endoscopic items for calculation of Beppu's and of NIEC prognostic scores were recorded on computerized cards. Patients were regularly interviewed every three months for one year and underwent an upper gastrointestinal endoscopy at enrollment, after six months and in case of bleeding. Within the twelve-month follow-up period, 29 out of the 200 patients (14%) bled and 52 out of 200 died (26%). In 16 of the 52 patients who died (59% of bleeding patients) death was directly related to gastrointestinal bleeding. Bleeding from oesophageal varices was endoscopically proven in 19/29 patients, in another 9 bleeding was classified as from unknown source and in one patient a bleeding gastric ulcer was diagnosed. Univariate analysis of all the recorded clinical, biochemical and endoscopic parameters, performed by Chi-square method and Fisher exact test showed that the presence of RWM (p < 0.001) was the only factor significantly associated to variceal bleeding within one year. Relationship between size of varices and bleeding was very close to the statistical significance but did not achieve it (p = 0.058).

    Numerous scoring systems have been developed for the prediction of outcome of variceal bleeding; however, only a few have been evaluated adequately. The object of this study was to improve the classical Child-Pugh score (CPS) and to test other scores from the literature. Patients (n = 82) with endoscopically confirmed variceal bleeding and long-term sclerotherapy were included in the study. Linear logistic regression (LR) was applied to different sets of prognostic variables with regard to 30-day mortality. In addition, scores from the literature were evaluated on the data set. Performance was measured by the accuracy and receiver-operating characteristic curves. The application of LR to all five CPS variables (accuracy, 80%) was superior to the classical CPS (70%). LR with selection from the CPS variables or from other sets of variables resulted in no improvement. Compared with CPS only three scores from the literature, mainly based on subsets of the CPS variables, showed an improved accuracy. It is concluded that CPS is still a good scoring system; however, it can be improved by statistical analysis using the same variables.

    Although the acute thrombosis and strangulation of haemorrhoids is a common condition, there is no consensus as to its most effective treatment. A PubMed search was undertaken for papers describing the aetiology and treatment of the acute complications of haemorrhoids. The anatomy and treatments for strangulated internal haemorrhoids and thrombosed perianal varices are discussed. Studies of the effectiveness and complications of conservative and operative treatments are reviewed. Ambiguities exist in the terminology used to describe the two separate pathologies that make up the acute complications of haemorrhoids. These complications have traditionally been treated conservatively. There is evidence that early operative intervention for strangulated internal haemorrhoids is safe and effective. A suggested algorithm for treatment is given, based on the published literature.

    AIM: To determine the clinical value of a splenorenal shunt plus pericardial devascularization (PCVD) in portal hypertension (PHT) patients with variceal bleeding. METHODS: From January 2008 to November 2012, 290 patients with cirrhotic portal hypertension were treated surgically in our department for the prevention of gastroesophageal variceal bleeding: 207 patients received a routine PCVD procedure (PCVD group), and 83 patients received a PCVD plus a splenorenal shunt procedure (combined group). Changes in hemodynamic parameters, rebleeding, encephalopathy, portal vein thrombosis, and mortality were analyzed. RESULTS: The free portal pressure decreased to 21.43 ± 4.35 mmHg in the combined group compared with 24.61 ± 5.42 mmHg in the PCVD group (P < 0.05). The changes in hemodynamic parameters were more significant in the combined group (P < 0.05). The long-term rebleeding rate was 7.22% in the combined group, which was lower than that in the PCVD group (14.93%), (P < 0.05). CONCLUSION: Devascularization plus splenorenal shunt is an effective and safe strategy to control esophagogastric variceal bleeding in PHT. It should be recommended as a first-line treatment for preventing bleeding in PHT patients when surgical interventions are considered. PMID:24409071

    Abuse of the drugs like amphetamine, cocaine and "Ecstasy" may be complicated by intracerebral, subdural or subarachnoid haemorrhage. Contrary to historical opinion, drug-related intracranial haemorrhage (ICH) is frequently related to an underlying vascular malformation. We report the case of an 18-year-old man with a history of Ecstasy abuse preceding the onset of severe occipital headache. Cerebral computed tomography revealed right-sided subarachnoid haemorrhage and cerebral angiography showed right-sided middle cerebral artery aneurysm of 1 cm diameter. The patient was treated surgically with aneurysm clipping. Three weeks after onset of intracranial haemorrhage, neurological examination demonstrated normal findings. A history of severe headache immediately after using amphetamine, Ecstasy, or cocaine should alert doctors to the possibility of intracerebral haemorrhage. Arteriography should be part of the evaluation of most young patients with stroke or non-traumatic ICH.

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

    Acute upper gastrointestinal bleeding (UGIB) affects large number of elderly with high rates of morbidity and mortality. Early identification and management of the factors predicting in-hospital mortality might decrease mortality. This study was conducted to identify the causes of acute UGIB and the predictors of in-hospital mortality in elderly Egyptian patients.286 elderly patients with acute UGIB were divided into: bleeding variceal group (161 patients) and bleeding nonvariceal group (125 patients). Patients' monitoring was done during hospitalization to identify the risk factors that might predict in-hospital mortality in elderly.Variceal bleeding was the most common cause of acute UGIB in elderly Egyptian patients. In-hospital mortality rate was 8.74%. Increasing age, hemodynamic instability at presentation, co-morbidities (especially liver cirrhosis associated with other co-morbidity) and failure to control bleeding were the predictors of in-hospital mortality.Increasing age, hemodynamic instability at presentation, co-morbidities (especially liver cirrhosis associated with other co-morbidity) and failure to control bleeding should be considered when triaging those patients for immediate resuscitation, close observation, and early treatment.

    Acute variceal haemorrhage (AVH) is associated with significant mortality. To determine outcome and factors associated with hospital mortality (HM) in patients with AVH admitted to intensive care unit (ICU) and to compare outcomes of patients requiring transfer to a tertiary ICU (transfer group, TG) to a local in-patient group (LG). A retrospective study of all adult patients (N = 177) admitted to ICU with AVH from 2000-2008 was performed. Median age was 48 years (16-80). Male represented 58%. Median MELD score was 16 (6-39), SOFA score was 8 (6-11). HM was higher in patients who had severe liver disease or critical illness measured by MELD, SOFA, APACHE II scores and number of failed organs (NFO), P < 0.05. Patients with day-1 lactate ≥ 2 mmol/L had increased HM (P < 0.001). MELD score performed as well as APACHE II, SOFA and NFO (P < 0.001) in predicting HM (AUROC = 0.84, 0.81, 0.79 and 0.82, respectively P > 0.05 for pair wise comparisons). Re-bleeding was associated with increased HM (56.9% vs. 31.6%, P = 0.002). The TG (n = 124) had less severe liver disease and critical illness and consequently had lower HM than local patients (32% vs. 57%, P = 0.002). TG patients with ≥2 endoscopies prior to transfer had increased 6-week mortality (P = 0.03). Time from bleeding to transfer ≥3 days was associated with re-bleeding (OR = 2.290, P = 0.043). MELD score was comparable to ICU prognostic models in predicting mortality. Blood lactate was also predictive of hospital mortality. Delays in referrals and repeated endoscopy were associated with increased re-bleeding and mortality in this group. © 2014 John Wiley & Sons Ltd.

    Endoscopic variceal ligation plus beta-blockers (EVL+BB) is currently recommended for variceal rebleeding prophylaxis, a recommendation that extends to all patients with cirrhosis with previous variceal bleeding irrespective of prognostic stage. Individualizing patient care is relevant, and in published studies on variceal rebleeding prophylaxis, there is a lack of information regarding response to therapy by prognostic stage. This study aimed at comparing EVL plus BB with monotherapy (EVL or BB) on all-source rebleeding and mortality in patients with cirrhosis and previous variceal bleeding stratified by cirrhosis severity (Child A versus B/C) by means of individual time-to-event patient data meta-analysis from randomized controlled trials. The study used individual data on 389 patients from three trials comparing EVL plus BB versus BB and 416 patients from four trials comparing EVL plus BB versus EVL. Compared with BB alone, EVL plus BB reduced overall rebleeding in Child A (incidence rate ratio 0.40; 95% confidence interval, 0.18-0.89; P = 0.025) but not in Child B/C, without differences in mortality. The effect of EVL on rebleeding was different according to Child (P for interaction <0.001). Conversely, compared with EVL, EVL plus BB reduced rebleeding in both Child A and B/C, with a significant reduction in mortality in Child B/C (incidence rate ratio 0.46; 95% confidence interval, 0.25-0.85; P = 0.013). Outcomes of therapies to prevent variceal rebleeding differ depending on cirrhosis severity: in patients with preserved liver function (Child A), combination therapy is recommended because it is more effective in preventing rebleeding, without modifying survival, while in patients with advanced liver failure (Child B/C), EVL alone carries an increased risk of rebleeding and death compared with combination therapy, underlining that BB is the key element of combination therapy.

    Adrenal haemorrhage (AH) is a rare but potentially devastating complication of heparin-induced thrombocytopenia (HIT). Neither the prevalence nor the natural history of AH due to HIT are known. The objectives of this study were to identify the spectrum of AH causes, to characterise the frequency of AH due to HIT and determine the natural history of HIT-associated AH. All patients with incident adrenal haemorrhage from January 2002 through June 2012 seen at the Mayo Clinic were identified. Over this time frame, there were a total of 115 patients with AH of which 11 cases (10%; mean age 67 ± 8 years; 73% female) were associated with HIT. Of these, all but one occurred in the postoperative setting and involved both adrenal glands (89%) with acute adrenal insufficiency at the time of diagnosis. Cases were found incidentally during an evaluation for fever, shock, abdominal pain or mental status changes. All HIT patients experienced venous thrombosis at other locations including deep venous thromboses (n=14), pulmonary emboli (n= 4) and arterial thrombosis (n=2). Four patients undergoing total knee arthroplasty had "spontaneous HIT" with AH in the absence of identifiable heparin exposure. Other causes of AH included trauma (29%), sepsis (15%), antiphospholipid antibody syndrome (10%), and metastatic disease (12%). In conclusion, AH is an important but seldom recognised presumed thrombotic complication of HIT, which usually occurs in the postoperative period, especially after orthopaedic procedures. This syndrome can occur in the apparent absence of heparin exposure, especially following major joint replacement surgery.

    Rapid and effective clearance of cell-free haemoglobin after subarachnoid haemorrhage (SAH) is important to prevent vasospasm and neurotoxicity and improve long-term outcome. Haemoglobin is avidly bound by haptoglobin, and the complex is cleared by CD163 expressed on the membrane surface of macrophages. We studied the kinetics of haemoglobin and haptoglobin in cerebrospinal fluid after SAH. We show that haemoglobin levels rise gradually after SAH. Haptoglobin levels rise acutely with aneurysmal rupture as a result of injection of blood into the subarachnoid space. Although levels decline as haemoglobin scavenging occurs, complete depletion of haptoglobin does not occur and levels start rising again, indicating saturation of CD163 sites available for haptoglobin-haemoglobin clearance. In a preliminary neuropathological study we demonstrate that meningeal CD163 expression is upregulated after SAH, in keeping with a proinflammatory state. However, loss of CD163 occurs in meningeal areas with overlying blood compared with areas without overlying blood. Becauses ADAM17 is the enzyme responsible for shedding membrane-bound CD163, its inhibition may be a potential therapeutic strategy after SAH.

    Some recent studies have found regression of liver cirrhosis after antiviral therapy in patients with hepatitis C virus (HCV)-related liver cirrhosis, but there have been no reports of complete regression of esophageal varices after interferon/peg-interferon and ribavirin combination therapy. We describe two cases of complete regression of esophageal varices and splenomegaly after interferon-alpha and ribavirin combination therapy in patients with HCV-related liver cirrhosis. Esophageal varices and splenomegaly regressed after 3 and 8 years of sustained virologic responses in cases 1 and 2, respectively. To our knowledge, this is the first study demonstrating that complications of liver cirrhosis, such as esophageal varices and splenomegaly, can regress after antiviral therapy in patients with HCV-related liver cirrhosis.

    Introduction Although the acute thrombosis and strangulation of haemorrhoids is a common condition, there is no consensus as to its most effective treatment. Methods A PubMed search was undertaken for papers describing the aetiology and treatment of the acute complications of haemorrhoids. Results The anatomy and treatments for strangulated internal haemorrhoids and thrombosed perianal varices are discussed. Studies of the effectiveness and complications of conservative and operative treatments are reviewed. Conclusions Ambiguities exist in the terminology used to describe the two separate pathologies that make up the acute complications of haemorrhoids. These complications have traditionally been treated conservatively. There is evidence that early operative intervention for strangulated internal haemorrhoids is safe and effective. A suggested algorithm for treatment is given, based on the published literature. PMID:25245728

    Haemorrhagic stroke is of significant healthcare concern due to its association with high mortality and lasting impact on the survivors' quality of life. Treatment decisions and clinical outcomes depend strongly on the size, spread and location of the haematoma. Non-contrast CT (NCCT) is the primary neuroimaging modality for haematoma assessment in haemorrhagic stroke diagnosis. Current procedures do not allow convenient NCCT-based haemorrhage volume calculation in clinical settings, while research-based approaches are yet to be tested for clinical utility; there is a demonstrated need for developing effective solutions. The project under review investigates the development of an automatic NCCT-based haematoma computation tool in support of accurate quantification of haematoma volumes. Several existing research methods for haematoma volume estimation are studied. Selected methods are tested using NCCT images of patients diagnosed with acute haemorrhagic stroke. For inter-rater and intrarater reliability evaluation, different raters will analyse haemorrhage volumes independently. The efficiency with respect to time of haematoma volume assessments will be examined to compare with the results from routine clinical evaluations and planimetry assessment that are known to be more accurate. The project will target the development of an enhanced solution by adapting existing methods and integrating machine learning algorithms. NCCT-based information of brain haemorrhage (eg, size, volume, location) and other relevant information (eg, age, sex, risk factor, comorbidities) will be used in relation to clinical outcomes with future project development. Validity and reliability of the solution will be examined for potential clinical utility. The project including procedures for deidentification of NCCT data has been ethically approved. The study involves secondary use of existing data and does not require new consent of participation. The team consists of clinical neuroimaging

    Achalasia is very uncommon, and rarely does achalasia co-exist with esophageal varices. We present a 62-year-old woman who was diagnosed with both achalasia and esophageal varices in December 2014 and had a past history of hematemesis. The patient's achalasia symptoms' Eckardt score was 9, and her hepatic function was Child-Pugh grade A6. After comprehensive assessment of the patient's health and discussion of the pros and cons of various therapies for achalasia, the patient underwent a peroral endoscopic myotomy. She was symptom-free after the operation and had no recurrence of achalasia symptoms at 20-month follow-up. No adverse events were reported. Peroral endoscopic myotomy for achalasia with esophageal varices has not been previously reported in the English literature.

    Forty-four cases of acute necrotic haemorrhagic pancreatitis are studied. Fourteen cases were treated medically by peritoneal dialysis, 20 were treated surgically of which 16 had been medically treated by peritoneal dialysis. Fifteen died or 34%. Forty-one patients, 93.1% presented 8 major complications on admission and 2 complications were observed during the course of medical treatment (pulmonary shock and high digestive haemorrhage). The post surgical complications are excluded from this study. We report in order of frequency; effusion of the large peritoneal cavity (37 cases : 84%), hypocalcaemia less than or equal to 8 mg% (21 cases : 47.7%), renal insufficiency defined by a creatinaemia greater than or equal 2 mg% (17 cases : 38.6%), state of shock (13 cases : 29.5%), severe neurological disorders (11 cases : 25%), peritoneal haemorrhage (3 cases : 4.5%), disseminated intravascular coagulation (1 case : 2.2%), acute rabdomyolysis (1 case : 2.2%). Certain cases are particularly derogatory : pulmonary shock : 2 cases -- 2 deaths (100%); hypocalcaemia less than or equal to 7 mg/ : 6 cases -- 5 deaths (83.3%); acute tubular necrosis : 8 cases -- 6 deaths (75%); hypocalcaemia less than or equal 8 mg% : 21 cases -- 12 deaths (57.1%); high digestive haemorrhage : 3 cases -- 1 death (33.3%); amber known brown peritoneal effusion : 27 cases -- 12 deaths (44.4%); shock : 13 cases -- 5 deaths (38.5%). When in the same patients, less than 3 complications were present, the mortality rate was 20.8%. If more than 3 signs were observed the mortality rate rose to 53.3%. Except for pulmonary shock, six major complications were needed to give 100% mortality rate.

    Non-invasive predictors of varices in cirrhosis would reduce the need for screening endoscopies. Platelet count and spleen size have been shown to be useful parameters, in mixed groups of cirrhotics with different aetiologies. We evaluated this in two homogeneous groups with cirrhosis due to hepatitis C and alcohol. Non-invasive predictors appear promising in the former group, but less so in the latter group.

    Ebola viruses are the causative agents of a severe form of viral haemorrhagic fever in man, designated Ebola haemorrhagic fever, and are endemic in regions of central Africa. The exception is the species Reston Ebola virus, which has not been associated with human disease and is found in the Philippines. Ebola virus constitutes an important local public health threat in Africa, with a worldwide effect through imported infections and through the fear of misuse for biological terrorism. Ebola virus is thought to also have a detrimental effect on the great ape population in Africa. Case-fatality rates of the African species in man are as high as 90%, with no prophylaxis or treatment available. Ebola virus infections are characterised by immune suppression and a systemic inflammatory response that causes impairment of the vascular, coagulation, and immune systems, leading to multiorgan failure and shock, and thus, in some ways, resembling septic shock.

    AIMS—To investigate the relation between cerebral blood flow on the first day of postnatal life and the severity of any subsequent germinal matrix haemorrhage-intraventricular haemorrhage (GMH-IVH).
METHODS—Cerebral blood flow was measured in 24 babies during the first 24 hours of life using near infrared spectroscopy. Repeated cerebral ultrasound examination was performed to define the maximum extent of GMH-IVH. Infants were classified as: normal scan, minor periventricular haemorrhage (haemorrhage that resolved), or severe GMH-IVH (haemorrhage distending the ventricles, that progressed to either post haemorrhagic dilatation or porencephalic cyst formation).
RESULTS—Cerebral blood flow was significantly lower in the infants with GMH-IVH (median 7.0 ml/100 g/min) than those without haemorrhage (median 12.2 ml/100 g/min), despite no difference in carbon dioxide tension and a higher mean arterial blood pressure. On subgroup analysis, those infants with severe GMH-IVH had the lowest cerebral blood flow.
CONCLUSION—A low cerebral blood flow on the first day of life is associated with the subsequent development of severe intraventricular haemorrhage.

    Roth spots (white-centred retinal haemorrhages) were classically described as septic emboli lodged in the retina of patients with subacute bacterial endocarditis. Indeed many have considered Roth spots pathognomonic for this condition. More recent histological evidence suggests, however, that they are not foci of bacterial abscess. Instead, they are nonspecific and may be found in many other diseases. A review of the histology and the pathogenesis of these white-centred haemorrhages will be provided, along with the work-up of the differential diagnosis.

    Atraumatic splenic rupture is a rare surgical emergency that is often attributed to neoplastic or infectious causes. Rarely, it has been identified to also occur in the setting of an acute severe sepsis and in cases of pelvic or splenic abscess formation post-appendicectomy. However, to our knowledge, the co-presentation of acute appendiceal abscess and splenic rupture has not been previously described. We present the case of a 67-year old male with decompensating haemorrhagic shock secondary to atraumatic splenic rupture on a background of an inadequately treated complicated appendicitis originally managed as diverticulitis with antibiotics in the community. Intra-operatively, in addition to a de-gloved, ruptured spleen; an acutely inflamed appendiceal abscess was also identified. A concomitant splenectomy, washout and appendicectomy and was therefore performed. Histopathological examination revealed a normal spleen with a stripped capsular layer. Mucosal ulceration, transmural inflammation and serositis of the appendix appeared to be consistent with acute appendicitis. Our case demonstrates how inadequately treated sepsis may predispose to an acute presentation of splenic rupture with associated haemorrhagic shock; which may initially be interpreted as septic shock. However, we demonstrate how insults such as sepsis and haemorrhagic shock may co-exist warranting careful consideration of possible dual pathologies in complex presentations which may be life-threatening. While the causal relationship between acute appendicitis and atraumatic spontaneous splenic rupture remains unclear, our case considers and highlights the importance of considering dual pathology in patients presenting in the acute setting.

    The poststroke acute and rehabilitation length of stay (LOS) are key markers of stroke care efficiency. This study aimed to describe the characteristics and identify the predictors of poststroke acute, rehabilitation and total LOS. This study also defined a subgroup of patients as "short" LOS and compared its complication rates and functional outcomes in rehabilitation with a "long" acute LOS group. A prospective cohort study (n = 1277) was conducted in a dedicated rehabilitation unit within a tertiary academic acute hospital over a 5-year period between 2004 and 2009. The functional independence measure (FIM) was the primary functional outcome measure in the rehabilitation phase. A group with an acute LOS of less than 7 days was defined as "short" acute LOS. Ischaemic strokes comprised 1019 (80%) of the cohort while the rest were haemorrhagic strokes. The mean acute and rehabilitation LOS were 9 ± 7 days and 18 ± 10 days, respectively. Haemorrhagic strokes and anterior circulation infarcts had significantly longer acute, rehabilitation and total LOS compared to posterior circulation and lacunar infarcts. The acute, rehabilitation and total LOS were significantly shorter for stroke admissions after 2007. There was poor correlation (r = 0.12) between the acute and rehabilitation LOS. In multivariate analyses, stroke type was strongly associated with acute LOS, while rehabilitation admission FIM scores were significantly associated with rehabilitation LOS. Patients in the short acute LOS group had fewer medical complications and similar FIM efficacies compared to the longer acute LOS group. Consideration for stroke type and initial functional status will facilitate programme planning that has a better estimation of the LOS duration, allowing for more equitable resource distribution across the inpatient stroke continuum. We advocate earlier transfers of appropriate patients to rehabilitation units as this ensures rehabilitation efficacy is maintained while the

    Crimea-Congo haemorrhagic fever is a tick-borne viral zoonosis with the potential of human-to-human transmission. The disease occurs in extensive areas in Asia, South-eastern Europe and Africa. Haemorrhagic manifestations constitute a prominent symptom of the late disease stage, with case fatality rates from 9 to 50%. The recent increase in the number of cases in Eastern Europe and the potential for nosocomial outbreaks indicate the advisability of diagnosis in every patient hospitalized in Italy with haemorrhagic fever.

    Adverse effect of excessive work on health has been suggested previously, but it was not documented in cerebrovascular diseases. The authors investigated whether excessive working conditions would associate with increased risk of haemorrhagic stroke. A nationwide matched case-control study database, which contains 940 cases of incident haemorrhagic stroke (498 intracerebral haemorrhages and 442 sub-arachnoid haemorrhages) with 1880 gender- and age- (± 5-year) matched controls, was analysed. Work-related information based on the regular job situation, including type of occupation, regular working time, duration of strenuous activity during regular work and shift work, was gathered through face-to-face interviews. Conditional logistic regression analyses were used for the multivariable analyses. Compared with white-collar workers, blue-collar workers had a higher risk for haemorrhagic stroke (odds ratio, 1.33 [95% confidence interval, 1.06-1.66]). Longer regular working time was associated with increased risk of haemorrhagic stroke [odds ratio, 1.38 (95% confidence interval, 1.05-1.81) for 8-12 h/day; odds ratio, 1.95 (95% confidence interval, 1.33-2.86) for ≥ 13 h/day; compared with ≤ 4 h/day]. Exposure to ≥ 8 h/week of strenuous activity also associated haemorrhagic stroke risk [odds ratio, 1.61 (95% confidence interval, 1.26-2.05); compared with no strenuous activity]. Shift work was not associated with haemorrhagic stroke (P = 0.98). Positive associations between working condition indices and haemorrhagic stroke risk were consistent regardless of haemorrhagic stroke sub-types and current employment status. Blue-collar occupation, longer regular working time and extended duration of strenuous activity during work may relate to an increased risk of haemorrhagic stroke. © 2012 The Authors.

    AIM: To prospectively assess the hemostatic efficacy of the endoscopic topical use of ankaferd blood stopper (ABS) in active non-variceal upper gastrointestinal system (GIS) bleeding. METHODS: Endoscopy was performed on 220 patients under suspiciency of GIS bleeding. Patients with active non-variceal upper gastrointestinal bleeding (NVUGIB) with a spurting or oozing type were included. Firstly, 8-10 cc of isotonic saline was sprayed to bleeding lesions. Then, 8 cc of ABS was applied on lesions in which bleeding continued after isotonic saline application. The other endoscopic therapeutic methods were applied on the lesions in which the bleeding did not stop after ABS. RESULTS: Twenty-seven patients had an active NVUGIB with a spurting or oozing type and 193 patients were excluded from the study since they did not have non-variceal active bleeding. 8 cc of ABS was sprayed on to the lesions of 26 patients whose bleeding continued after isotonic saline and in 19 of them, bleeding stopped after ABS. Other endoscopic treatment methods were applied to the remaining patients and the bleeding was stopped with these interventions in 6 of 7 patients. CONCLUSION: ABS is an effective method on NVUGIB, particularly on young patients with no coagulopathy. ABS may be considered as part of a combination treatment with other endoscopic methods.

    A 76-year-old male suffering from nephrolithiasis developed a shock syndrome 5 days after extracorporal shock wave lithotripsy (ESWL). CT scan of the abdomen showed massive haemorrhage around the right kidney. Although nephrectomy was performed immediately, the haemorrhage could not be controlled. Numerous units of erythrocytes were transfused, but the patient died. The autopsy revealed massive retroperitoneal haemorrhage around the right kidney. The kidney showed a subcapsular haematoma and a rupture of the capsule. The right renal artery was dissected. The inferior vena cava was lacerated. Accordingly, a hemorrhagic shock as the cause of death was determined, which might mainly have resulted from the laceration of the inferior vena cava due to ESWL. ESWL seems to be a relatively non-invasive modality, but one of its severe complications is perirenal hematoma. The injuries of the blood vessels might have been caused by excessive shock waves. Subsequently, anticoagulation therapy had been resumed 3 days after EWSL, which might have triggered the haemorrhage. Physicians should note that a haemorrhage after an ESWL can occur and they should pay attention to the postoperative management in aged individuals especially when they are under anticoagulation therapy.

    Haemorrhagic disorders like Postpartum haemorrhage and Dengue haemorrhagic fever are life threatening and requires an active and efficient transfusion service that could provide the most appropriate blood product which could be effective in managing them. This would essentially require prompt identification of the coagulopathy so that the best available product can be given to the bleeding patient to correct the identified haemostatic defect which will help control the bleeding. This would only be possible if the transfusion service has a laboratory to correctly detect the haemostatic defect and that too with an accuracy and precision which is ensured by a good laboratory quality assurance practices. These same processes are necessary for the transfusion services to ensure the quality of the blood products manufactured by them and that it contains adequate amounts of haemostasis factors which will be good to be effective in the management of haemorrhagic disorders. These issues are discussed in detail individually in the management of postpartum haemorrhage and Dengue haemorrhagic fever including when these can help in the use of rFVIIa in Dengue haemorrhagic fever. The requirements to ensure good-quality blood products are made available for the management of these disorders and the same have also been described. © 2016 John Wiley & Sons Ltd.

    The incidence of hypopituitarism after aneurysmal subarachnoid haemorrhage (SAH) is unclear from the conflicting reports in the literature. As routine neuroendocrine screening for hypopituitarism for all patients would be costly and logistically difficult, there is a need for precise data on the frequency of hypopituitarism and on factors which might predict the later development of pituitary dysfunction. We aimed to: (i) Establish the incidence of long-term hypopituitarism in patients with aneurysmal SAH. (ii) Determine whether data from patients' acute admission with SAH could predict the occurrence of long-term hypopituitarism. One hundred patients were studied prospectively from the time of presentation with acute SAH. Plasma cortisol, plasma sodium and a variety of clinical and haemodynamic parameters were sequentially measured for the first 12 days of their acute admission. Forty-one patients then underwent dynamic pituitary testing at median 15 months following SAH (range 7-30 months), with insulin tolerance test (ITT) or, if contraindicated, a glucagon stimulation test (GST) plus short synacthen test (SST). If symptoms of cranial diabetes insipidus (CDI) were present, a water deprivation test was also performed. Forty-one patients attended for follow-up dynamic pituitary testing. Although 14 of 100 had acute glucocorticoid deficiency immediately following SAH, only two of 41 had long-term adrenocorticotrophic hormone (ACTH) deficiency and four of 41 had growth hormone (GH) deficiency. None were hypothyroid or gonadotrophin deficient. None had chronic CDI or hyponatraemia. There was no association between acute glucocorticoid deficiency, acute CDI or acute hyponatraemia and long-term pituitary dysfunction. Both anterior and posterior hypopituitarism are very uncommon following SAH and are not predicted by acute clinical, haemodynamic or endocrinological parameters. Routine neuroendocrine screening is not justified in SAH patients. © 2014 John Wiley & Sons

    Background Oesophageal varices and gastrointestinal bleeding are common complications of liver cirrhosis. More rarely, oesophageal varices occur in patients with non-cirrhotic portal hypertension that results from thromboses of portal or splanchnic veins. Case Report We describe 2 young men who initially presented with varices as a result of portal vein thromboses. In the clinical follow-up, both were tested positive for a JAK2 mutation and consequently diagnosed with myeloproliferative neoplasms (MPNs). In an attempt to characterise the frequency of gastrointestinal complications in patients with JAK2-positive MPNs, we retrospectively analysed all known affected patients from our clinic for the diagnosis of portal vein thromboses and oesophageal varices. Strikingly, 48% of those who had received an oesophagogastroduodenoscopy had detectable oesophageal or gastric varices, and 82% of those suffered from portal or splanchnic vein thromboses. Conclusion While the association between JAK2, myeloproliferative disease and thrombotic events is well established, patients with idiopathic oesophageal varices are not regularly tested for JAK2 mutations. However, the occurrence of oesophageal varices may be the first presenting symptom of a MPN with a JAK2 mutation, and affected patients may profit from a close haematological monitoring to assure the early detection of developing MPN.

    Early blood pressure-lowering treatment appears to be beneficial in patients with acute intracerebral haemorrhage and potentially in ischaemic stroke. We used a new method for analysis of vascular events in the Scandinavian Candesartan Acute Stroke Trial to see if the effect was dependent on the timing of treatment. Scandinavian Candesartan Acute Stroke Trial was a randomized controlled and placebo-controlled trial of candesartan within 30 h of ischaemic or haemorrhagic stroke. Of 2029 patients, 231 (11.4%) had a vascular event (vascular death, nonfatal stroke or nonfatal myocardial infarction) during the first 6 months. The modified Rankin Scale (mRS) score following a vascular event was used to categorize vascular events in order of severity: no event (n = 1798), minor (mRS 0-2, n = 59), moderately severe (mRS 3-4, n = 57) and major event (mRS 5-6, n = 115). We used ordinal logistic regression for analysis and adjusted for predefined prognostic variables. Candesartan had no overall effect on vascular events (adjusted common odds ratio 1.11, 95% confidence interval 0.84-1.47, P = 0.48), and the effects were the same in ischaemic and haemorrhagic stroke. Among the patients treated within 6 h, the adjusted common odds ratio for vascular events was 0.37, 95% confidence interval 0.16-0.84, P = 0.02, and there was no heterogeneity of effect between ischaemic and haemorrhagic strokes. Ordinal analysis of vascular events showed no overall effect of candesartan in the subacute phase of stroke. The effect of treatment given within 6 h of stroke onset appears promising, and will be addressed in ongoing trials. Ordinal analysis of vascular events is feasible and can be used in future trials.

    To evaluate the clinical response and success rate after periuterine varices embolization in patients with chronic pelvic pain secondary to pelvic congestion syndrome and to report the safety of endovascular treatment and its rate of complications. Retrospective cohort of patients undergoing endovascular treatment of pelvic congestion syndrome in our department from January 2012 to November 2015. Data were analyzed based on patient background, imaging findings, embolized veins, rate of complications, and clinical response as indicated by the visual analog pain scale. We performed periuterine varices embolization in 22 patients during the study, four of which required a second embolization. Seventeen patients reported a reduction in pelvic pain after the first embolization and three patients reported a reduction in pelvic pain after the second embolization. Minor complications were observed in our patients, such as postural hypotension, postoperative pain, and venous perforation during the procedure, without clinical repercussion. Periuterine varices embolization in patients with chronic pelvic pain secondary to pelvic congestion syndrome appears to be an effective and safe technique.

    It has been hypothesised that paroxysmal coughing in infantile pertussis (whooping cough) could produce retinal haemorrhages identical to those seen in abusive head trauma. We aimed to test this hypothesis. This is a prospective study of infants hospitalised with pertussis in Auckland, New Zealand, from 2009 to 2014. The clinical severity of pertussis was categorised. All infants recruited had retinal examination through dilated pupils by the paediatric ophthalmology service using an indirect ophthalmoscope. Forty-eight infants with pertussis, aged 3 weeks to 7 months, were examined after a mean of 18 days of coughing. Thirty-nine had severe pertussis and nine had mild pertussis. All had paroxysmal cough, and all were still coughing at the time of examination. No retinal haemorrhages were seen. We found no evidence to support the hypothesis that pertussis may cause the pattern of retinal haemorrhages seen in abusive head trauma in infants. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    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

    This study aimed to evaluate the efficacy and safety of emergency variceal ligation for the prevention of rebleeding in cirrhotic patients who are found on initial endoscopy to have blood clots in the stomach but no actively bleeding esophageal and gastric varices or stigmata. This study included 28 cirrhotic patients who underwent emergency prophylactic EVL and 41 who underwent an elective intervention between January 2009 and June 2014. Clinical outcomes were analyzed, including the rebleeding, 6-week mortality, and rebleeding-free survival rates. The rebleeding rate was higher in the emergency than in the elective group (28.6% vs. 7.3%, P =0.041). Multivariate analysis showed that emergency prophylactic EVL (odds ratio [OR] = 7.4, 95% confidence interval [CI]=1.634.8, P =0.012) and Child-Pugh score C (OR=10.6, 95% CI=1.4-80.8, P =0.022) were associated with rebleeding. In the emergency group, the gastric varices were associated with rebleeding (OR=12.0, 95% CI=1.7-83.5, P =0.012). Emergency EVL may be associated with variceal rebleeding when blood clots are present in the stomach without active esophageal and gastric variceal bleeding or stigmata. Elective intervention should be considered as a safer strategy for preventing variceal rebleeding in this situation.

    At present, there is no perfect noninvasive method to assess portal hypertension and esophageal varices. Early predicting esophageal varices can provide evidence for managing cirrhotic patients. We aimed to further investigate von Willebrand factor (vWF) as a noninvasive predictor of portal hypertension, especially of esophageal varices. A total of 60 hepatitis B patients with cirrhosis and 45 healthy subjects were enrolled in this study. Levels of six markers were examined. All patients underwent hepatic venous pressure gradient (HVPG) and esophagogastroduodenoscopy. We evaluated the performance of six factors for diagnosis of portal hypertension and esophageal varices. The vWF levels in liver tissues were observed by immunohistochemistry. Correlations between the level of vWF in liver tissues and HVPG and between levels of vWF in tissues and plasma were examined. Cutoff values of plasma vWF (1510.5 mU/mL and 1701 mU/mL) showed high positive predictive value (PPV, 90.2% and 87.5%) in predicting clinically significant portal hypertension and severe portal hypertension. Cutoff values of vWF (1414 mU/ml and 1990 mU/mL, PPV 90.3% and 86.3%, respectively) were provided to detect the presence and degree of esophageal varices. Linear correlations were observed between levels of vWF in liver tissues and HVPG (r(2) = 0.552, p < 0.001) and between the level of vWF in liver tissues and in plasma (r(2) = 0.461, p < 0.001). The vWF is a noninvasive predictor of portal hypertension and esophageal varices in hepatitis B patients with cirrhosis. Increased levels of vWF in liver tissues may induce the elevated plasma vWF levels, but molecular mechanism is needed for further study.

  2. Upper non-variceal gastrointestinal bleeding - review the effectiveness of endoscopic hemostasis methods

    2015-01-01

    Upper non-variceal gastrointestinal bleeding is a condition that requires immediate medical intervention and has a high associated mortality rate (exceeding 10%). The vast majority of upper gastrointestinal bleeding cases are due to peptic ulcers. Helicobacter pylori infection, non-steroidal anti-inflammatory drugs and aspirin are the main risk factors for peptic ulcer disease. Endoscopic therapy has generally been recommended as the first-line treatment for upper gastrointestinal bleeding as it has been shown to reduce recurrent bleeding, the need for surgery and mortality. Early endoscopy (within 24 h of hospital admission) has a greater impact than delayed endoscopy on the length of hospital stay and requirement for blood transfusion. This paper aims to review and compare the efficacy of the types of endoscopic hemostasis most commonly used to control non-variceal gastrointestinal bleeding by pooling data from the literature.

    Aims In the past few years an increasing number of bleeding disorders have been reported in association with the use of selective serotonin reuptake inhibitors (SSRIs), including serious cases of intracranial haemorrhage, raising concerns about the safety of this class of drugs. The present study was performed to test the hypothesis of an increased risk of intracranial haemorrhage associated with the use of SSRIs. Methods We carried out a case-control study nested in a cohort of antidepressants users with the UK-based General Practice Research Database (GPRD) as the primary source of information. The study cohort encompassed subjects aged between 18 and 79 years who received a first-time prescription for any antidepressant from January, 1990 to October, 1997. Patients with presenting conditions or treatments that could be associated with an increased risk of intracranial haemorrhage were excluded from the cohort. Patients were followed-up until the occurrence of an idiopathic intracranial haemorrhage. Up to four controls per case, matched on age, sex, calendar time and practice were randomly selected from the study cohort. We estimated adjusted odds ratios and 95% confidence intervals of intracranial haemorrhage with current use of SSRIs and other antidepressants as compared with nonuse using conditional logistic regression. Results We identified 65 cases of idiopathic intracranial haemorrhage and 254 matched controls. Current exposure to SSRIs was ascertained in 7 cases (10.8%) and 24 controls (9.7%) resulting in an adjusted OR (95%CI) of 0.8 (0.3,2.3). The estimate for ‘other antidepressants’ was 0.7 (0.3,1.6). The effect measures were not modified by gender or age. No effect related to dose or treatment duration was detected. The risk estimates did not change according to the location of bleeding (intracerebral or subarachnoid). Conclusions Our results are not compatible with a major increased risk of intracranial haemorrhage among users of SSRIs or other

    To determine the etiology and outcome of Acute Renal Failure (ARF) in pregnancy. A case series. Nephrology Department of the Jinnah Postgraduate Medical Centre, Karachi, from August 2007 to July 2008. Pregnant women who were healthy previously and had developed ARF, diagnosed on oliguria (urine output <400 ml/day) and mounting azotemia (serum creatinine > 2 mg%) were included in the study. Percutaneous renal biopsy was performed for delayed recovery, i.e. after three weeks. Patients were followed up for a period of 6 months. Percentages were calculated for qualitative variables i.e. causes of ARF, mortality, morbidity and outcome in form of complete recovery, partial recovery, demise and non-recovery. A total of 43 patients with pregnancy-related ARF were included in the study. The puerperal group comprised 36 patients (83.7%). Haemorrhage was the etiology for ARF in 25 (58.1%), antepartum haemorrhage APH in 8 (18.6%) and postpartum haemorrhage PPH in 16 (37.2%) of patients. In 12 (27.9%), puerperal sepsis was the etiological factor, while 4 (9.3%) patients had DIC on presentation. Pre-eclampsia, eclampsia and HELLP syndrome accounted for 5 (11.6%). While 1 (2.3%) was diagnosed with hemolytic uremic syndrome and another one was diagnosed as ARF secondary to hypotension produced by hyperemesis gravidarum. Renal biopsy was performed in 31 patients showing that 10 had acute cortical necrosis and 21 had acute tubular necrosis. Maternal mortality was 16.2% (n=7). Of the 36 (83.7%) surviving patients, 18 (41.4%) had complete recovery of renal function; 12 (27.9%) had partial recovery; and 6 (13.9%) required chronic dialysis. Pregnancy-related ARF was associated with poor outcome. Antepartum and postpartum haemorrhage were the most common cause of ARF in pregnancy.

    The epidemic of abuse of the so-called 'designer drugs' amphetamine, cocaine and ecstasy--is fast replacing traditional aetiological factors as the largest cause of intracerebral haemorrhage among young adults. Traditional teaching is that these represent hypertensive haemorrhages. Recent reports, however, have indicated that these patients may harbour underlying vascular malformations. We review 13 patients with a positive history of drug abuse preceding the onset of intracerebral haemorrhage. These patients presented to the National Hospital for Neurology and Neurosurgery in central London over a 7-month period. Of the 13 patients (eight male, five female), average age 31 years (19-43) years), 10 were well enough to undergo cerebral angiography. Intracranial aneurysms were demonstrated in six patients and arteriovenous malformations in three patients. In only one of the patients was the angiogram normal. A further patient was subsequently shown to have a middle cerebral artery aneurysm at autopsy. The epidemiology, pharmacology and systemic effects of these drugs are considered. The mechanisms by which these compounds cause intracerebral complications and their influence on prognosis are discussed. The incidence of intracerebral haemorrhage (ICH), ischaemic cerebral infarctions and subarachnoid haemorrhage (SAH) following drug abuse is increasing. Contrary to historical opinion, drug-related ICH is frequently related to an underlying vascular malformation. Arteriography should be part of the evaluation of most young patients with nontraumatic ICH. A thorough history focusing on the use of illicit substances and toxicological screening of urine and serum should be part of the evaluation of any young patient with a stroke.

    Early brain injury/ischaemia (EBI) is a serious complication early after subarachnoid haemorrhage (SAH) that contributes to development of delayed cerebral ischaemia (DCI). This study aimed to determine the role of inotropic cardiac support using milrinone (MIL) on restoring acute cerebral hypoperfusion attributable to EBI and improving outcomes after experimental SAH. Forty-three male C57BL/6 mice were assigned to either sham surgery (SAH-sham), SAH induced by endovascular perforation plus postconditioning with 2% isoflurane (Control), or SAH plus isoflurane combined with MIL with and without hypoxia-inducible factor inhibitor (HIF-I) pretreatment. Cardiac output (CO) during intravenous MIL infusion (0.25-0.75 μg/kg/min) between 1.5 and 2.5 hours after SAH induction was monitored with Doppler echocardiography. Magnetic resonance imaging (MRI)-continuous arterial spin labelling was used for quantitative cerebral blood flow (CBF) measurements. Neurobehavioral function was assessed daily by neurological score and open field test. DCI was analyzed 3 days later by determining infarction on MRI. Mild reduction of cardiac output (CO) and global cerebral blood flow (CBF) depression were notable early after SAH. MIL increased CO in a dose-dependent manner (P<.001), which was accompanied by improved hypoperfusion, incidence of DCI and functional recovery than Control (P<.05). The neuroprotective effects afforded by MIL or Control were attenuated by hypoxia-inducible factor (HIF) inhibition (P<.05). These results suggest that MIL improves acute hypoperfusion by its inotropic effect, leading to neurobehavioral improvement in mice after severe SAH, in which HIF may be acting as a critical mediator. © 2017 John Wiley & Sons Australia, Ltd.

    This report describes a series of ten cases of fulminant pulmonary haemorrhage in dogs following envenomation by the eastern brown snake (Pseudonaja textilis) in south eastern Queensland, Australia. All cases were presented for veterinary treatment during 2011-2018 at a specialist veterinary emergency centre. Each case received prompt antivenom treatment and supportive care. Pulmonary haemorrhage was diagnosed based on clinical examination; overt haemoptysis; thoracic radiographic demonstration of a diffuse alveolar pattern; and, the presence of venom induced consumptive coagulopathy. The median elapsed time from hospital admission to onset of haemoptysis was 2 h (range 0-18 h). In 80% (8/10) of cases endotracheal intubation was required, whilst 20% (2/10) were successfully treated with mask oxygen supplementation alone, and 40% (4/10) received mechanical ventilation; but only 25% (1/4) of these survived to hospital discharge. Fresh frozen canine plasma was administered to 70% (7/10) of cases and 43% (3/7) of these survived. Of the total number of cases presented for treatment, 30% (3/10) survived to hospital discharge, 60% (6/10) were euthanised due to poor prognosis and 10% (1/10) died from cardiac arrest. Initial serum brown snake venom antigen levels were retrospectively measured from frozen serum samples by venom specific sandwich ELISA in two dogs at 154 ng/mL (survived) and 3607 ng/mL (euthanised); no free venom was detected post-antivenom. Dogs that survived were discharged from hospital without apparent complications. Pulmonary haemorrhage is an uncommon event following envenomation by P. textilis in dogs and has not been described in similarly envenomed humans. This case series highlights the potential for fulminant and fatal pulmonary haemorrhage in dogs following eastern brown snake envenomation. Copyright © 2018 Elsevier Ltd. All rights reserved.

    In a study of 55 persons with dengue haemorrhagic fever—36 of whom showed the dengue shock syndrome—clinical, haematological, virological, and serological changes were correlated with serial measurements of complement components and immunopathological studies. Viruses dengue-1 or dengue-2 were isolated from the sera of 9 patients. Serological responses indicative of secondary dengue virus infections were observed in 53 patients; 2 (infants) had primary infections. During the acute phase of the disease, dengue antibody titres rose logarithmically. Marked depression of complement components, especially C3, was observed. Activation of both the classical and alternative complement pathways was demonstrated, with depression of both C4 and C3 proactivator levels in most instances, although in some cases it appeared that one mechanism was involved to a greater extent than the other. The level of depression of C3 was correlated with the severity of the disease. Relatively stable transferrin levels indicated that depletion of complement proteins was not primarily due to extravasation. Fibrinogen levels were depressed and fibrinogen split products were found in the plasma. The accumulated data provide further evidence of the central role that activated complement components play in the pathogenesis of dengue haemorrhagic fever. PMID:4575523

    Portal hypertension can be caused by a wide variety of conditions. It frequently presents with bleeding from esophageal varices. The approach to acute variceal hemorrhage in children is a stepwise progression from least invasive to most invasive. Management of acute variceal bleeding is straightforward. But data on primary prophylaxis and long term management prevention of recurrent variceal bleeding in children is scarce, therefore prospective multicenter trials are needed to establish best practices.

    Delayed thrombolytic treatment with recombinant tissue plasminogen activator (tPA) may exacerbate blood-brain barrier breakdown after ischaemic stroke and lead to lethal haemorrhagic transformation. The immune system is a dynamic modulator of stroke response, and excessive immune cell accumulation in the cerebral vasculature is associated with compromised integrity of the blood-brain barrier. We previously reported that regulatory T cells, which function to suppress excessive immune responses, ameliorated blood-brain barrier damage after cerebral ischaemia. This study assessed the impact of regulatory T cells in the context of tPA-induced brain haemorrhage and investigated the underlying mechanisms of action. The number of circulating regulatory T cells in stroke patients was dramatically reduced soon after stroke onset (84 acute ischaemic stroke patients with or without intravenous tPA treatment, compared to 115 age and gender-matched healthy controls). Although stroke patients without tPA treatment gradually repopulated the numbers of circulating regulatory T cells within the first 7 days after stroke, post-ischaemic tPA treatment led to sustained suppression of regulatory T cells in the blood. We then used the murine suture and embolic middle cerebral artery occlusion models of stroke to investigate the therapeutic potential of adoptive regulatory T cell transfer against tPA-induced haemorrhagic transformation. Delayed administration of tPA (10 mg/kg) resulted in haemorrhagic transformation in the ischaemic territory 1 day after ischaemia. When regulatory T cells (2 × 106/mouse) were intravenously administered immediately after delayed tPA treatment in ischaemic mice, haemorrhagic transformation was significantly decreased, and this was associated with improved sensorimotor functions. Blood-brain barrier disruption and tight junction damages were observed in the presence of delayed tPA after stroke, but were mitigated by regulatory T cell transfer. Mechanistic

    Background Some cases of subarachnoid haemorrhage (SAH) have been associated with vigorous physical activity, including sports. Our research aimed to describe the association between SAH and sports and to identify the types of sports that were more frequently found as precipitating factors in a tertiary single-centre SAH register. Methods We retrieved information from a prospectively collected SAH registry and reviewed discharge notes of acute SAH patients admitted to the Stroke Unit of Hospital de Santa Maria, Lisbon, between 1995 and 2014. Results Out of 738 patients included in the analysis, 424 (57.5%) cases of SAH were preceded by physical activity. Nine cases (1.2%) were associated with sports, namely running (2 cases), aerobics (2 cases), cycling, body balance, dance, surf and windsurf. Patients with SAH while practicing sports were younger than controls (average age 43.1 vs. 57.0 years; p = 0.007). In 1 patient, there was a report of trauma to the neck. Patients in the sports group only had Hunt and Hess scale grades 1 (11.1%) or 2 (88.9%) at admission, while patients in the control group had a wider distribution in severity. Conclusions Our findings indicate that SAH precipitated by sports is not very frequent and is uncommonly related to trauma. Patients who suffered SAH associated with sports were younger and apparently had a milder clinical presentation. PMID:26648972

    Despite a pronounced reduction of lethality rates due to upper gastrointestinal bleeding, esophageal variceal bleeding remains a challenge for the endoscopist and still accounts for a mortality rate of up to 40% within the first 6 weeks. A relevant proportion of patients with esophageal variceal bleeding remains refractory to standard therapy, thus making a call for additional tools to achieve hemostasis. Self-expandable metal stents (SEMS) incorporate such a tool. We evaluated a total number of 582 patients admitted to our endoscopy unit with the diagnosis "gastrointestinal bleeding" according to our documentation software between 2011 and 2014. 82 patients suffered from esophageal variceal bleeding, out of which 11 cases were refractory to standard therapy leading to SEMS application. Patients with esophageal malignancy, fistula, or stricture and a non-esophageal variceal bleeding source were excluded from the analysis. A retrospective analysis reporting a series of clinically relevant parameters in combination with bleeding control rates and adverse events was performed. The initial bleeding control rate after SEMS application was 100%. Despite this success, we observed a 27% mortality rate within the first 42 days. All of these patients died due to non-directly hemorrhage-associated reasons. The majority of patients exhibited an extensive demand of medical care with prolonged hospital stay. Common complications were hepatic decompensation, pulmonary infection and decline of renal function. Interestingly, we found in 7 out of 11 patients (63.6%) stent dislocation at time of control endoscopy 24 h after hemostasis or at time of stent removal. The presence of hiatal hernia did not affect obviously stent dislocation rates. Refractory patients had significantly longer hospitalization times compared to non-refractory patients. Self-expandable metal stents for esophageal variceal bleeding seem to be safe and efficient after failed standard therapy. Stent migration

    2009-10-01

    Sepsis and/or acute blood loss can be encoutered as an emergency condition in gynaecology, especially in women with ectopic pregnancy/miscarriage, acute pelvic inflammatory disease (PID)/tuboovarian abscesses, post-puerperal sepsis/haemorrhage and even in postoperative scenarios. If underestimated or suboptimally treated, both can lead to an inadequate tissue perfusion (defined as shock) and the development of multi-organ failure. Morbidity and mortality after development of one of the shock syndromes (septic or haemorrhagic) correlates directly with the duration and severity of the malperfusion. The patient's prognosis depends on a prompt diagnosis of the presence of shock and immediate resuscitation to predefined physiological end-points, often before the cause of the shock has been identified. In septic shock, hypotension is primarily treated with fluid administration and eventually vasopressors, if required, in order to improve the circulation. Timely administration of antibiotics, control of infectious foci, appropriate use of corticoids and recombinant human activated protein C, tight glucose control, prophylaxis of deep vein thrombosis and stress ulcer prevention complete the therapy of septic shock. In haemorrhagic shock, the treatment primarily involves controlling haemorrhage, reversal of possible coagulopathy and administration of sufficient volumes of fluids and blood products to restore normal tissue perfusion.

    Neurogenic inflammation is linked to urinary bladder overactivity development. Cyclophosphamide (CYP) damages all mucosal defence lines of urinary bladder and induces cystitis with overactivity. The aim of this study was to estimate the effect of CYP on rat urinary bladder function, histological structure and mastocytes numbers following acute and chronic CYP treatment. Fourty two female rats were divided into four groups: I (control), II (acute cystitis), III (chronic cystitis), IV (sham group). Acute and chronic cystitis were induced by CYP in single dose and four doses (1(st), 3(rd), 5(th), 7(th) day), respectively. In group I-III the cystometric evaluation was performed. Sections of the bladder were stained with HE and toluidine blue for the detection of mastocytes. The severity of inflammation was examined according to mucosal abrasion, haemorrhage, leukocyte infiltration and oedema. Acute and chronic CYP treatment caused inflammatory macroscopic and microscopic changes (mucosal abrasion, haemorrhage, oedema) and increased infiltration of inflammatory cells in urinary bladder. Acute treatment induced the infiltration of mastocytes within bladder wall contrary to chronic one decrement. Acute treatment caused more severe mucosal abrasion, whereas chronic one revealed more developed haemorrhage changes. Additionally, cystometric evaluation revealed urinary bladder overactivity development in both types of cystitis. Basal pressure and detrusor overactivity index after acute treatment increased considerably in comparison with the increase obtained after chronic one. Our results proved that acute model of CYP-induced cystitis in rats is more credible for further evaluation of neurogenic inflammation response in pathogenesis of overactive bladder as compared to chronic one.

    Protein tyrosine phosphatase 1B (PTP1B) inhibitors as potential therapies for diabetes and obesity have attracted much attention in recent years. Six varic acid analogues were isolated from two strains of fungi and evaluated for PTP1B inhibition activities. The structure-activity relationships were also characterized and predicted by molecular modeling. Further kinetic studies indicated the reversible and competitive inhibition manner of varic acid analogues. Trivaric acid showed insulin-sensitizing effect not only in vitro but also in vivo, representing a promising lead compound for further optimization. Copyright © 2017 Elsevier Ltd.

    AIM: To investigate whether liver lobe volume and albumin (ALB) could predict the presence and severity of liver cirrhosis, and esophageal varices. METHODS: Seventy-one cirrhotic patients with hepatitis B and 21 healthy individuals were enrolled in this study. All the participants underwent abdominal enhanced magnetic resonance imaging to measure each liver lobe volume, and biochemical workup for testing ALB and Child-Pugh class. All cirrhotic patients underwent upper gastrointestinal endoscopy to show the presence of cirrhotic esophageal varices. Right liver lobe volume (RV), left medial liver lobe volume (LMV), left lateral liver lobe volume (LLV), and caudate lobe volume (CV) were measured using enhanced magnetic resonance imaging. The ratios of RV to ALB (RV/ALB), LMV to ALB (LMV/ALB), LLV to ALB (LLV/ALB) and CV to ALB (CV/ALB) were calculated. Statistical analyses were performed to determine whether and how the combination of liver lobe volume measured using magnetic resonance imaging and albumin could predict the presence and severity of liver cirrhosis, and the presence of esophageal varices. RESULTS: RV, LMV, LLV and CV decreased (r = -0.51-0.373; all P < 0.05), while RV/ALB increased (r = 0.424; P < 0.05), with the progress of Child-Pugh class of liver cirrhosis. RV, LMV, CV, LLV/ALB and CV/ALB could identify presence of liver cirrhosis; LLV and LMV could distinguish Child-Pugh class A from B; RV, LMV, LLV, CV, RV/ALB and LLV/ALB could distinguish class A from C; RV and LLV/ALB could differentiate B from C; and RV, RV/ALB and CV/ALB could identify presence of esophageal varices (all P < 0.05). Among these parameters, CV/ALB could best identify the presence of liver cirrhosis, with an area under receiver operating characteristic curve (AUC) of 0.860, a sensitivity of 82.0% and a specificity of 83.0%. LLV could best distinguish class A from B, with an AUC of 0.761, a sensitivity of 74.4% and a specificity of 73.1%. RV could best distinguish class A from C

    To study hospital mortality associated with upper gastrointestinal hemorrhages due to variceal bleeding in the department of hepatology and gastroenterology at the Lome Campus University Hospital. This retrospective cross-sectional and analytic study examined the 55 patients admitted for variceal bleeding on upper endoscopies during the 3-year period from January 1, 2008, through December 31, 2010. These patients accounted for 4.1% of all hospitalizations during the study period in the department. Their average age was 35 years, and their sex-ratio 4. A history of chronic liver disease was found in 65.5%. Liver cirrhosis was the principal cause of the esophageal varices, complicated by hepatocellular carcinoma in 30.9% of them. The mortality rate was 25.5% and was not related to the cause of portal hypertension. All the patients with a recurrence of bleeding died. Mortality was associated with jaundice. Blood transfusion did not significantly improve the prognosis. the mortality rate among patients with upper gastrointestinal hemorrhage linked to variceal bleeding is high in our unit. The prevention of hepatitis virus B is important because it is the main cause of chronic liver disease causing portal hypertension in our department.

    To describe the population admitted in an emergency department of a teaching hospital for severe bleeding associated with direct oral anticoagulants (DOAC). During a three-year period (2012-2014) patients older than 16 years were prospectively identified by haemorrhagic symptoms from computerised requests. At least one of the following criteria defined major haemorrhage: haemorrhagic shock, unstable haemodynamic, need for transfusion or haemostatic procedure, or a life threatening location. Fifty four patients, 23 receiving dabigatran, 30 rivaroxaban and one apixaban were included, 2 in 2012, 35 in 2013 and 17 in 2014. Median age was 84 years (range 63-99) with a sex ratio of 1.16. Haemorrhagic complications were gastrointestinal (n=27), intracranial (n=12) or miscellaneous (n=15). Indication of DOAC was stroke prevention in atrial fibrillation in 49 cases and deep vein thrombosis in 5 cases. Hospitalization was required for 45 patients (83%) with a mean length of stay of 8.5 days. Sixteen patients needed intensive care. Reversal therapy was prescribed in 11 patients. At 1 month, overall mortality was 24%, reaching 41.7% for intracranial haemorrhage. Among surviving patients, DOAC was stopped in 10 cases, continued in 17 patients and switched for other antithrombotic in 17 patients. Our study contributes to the post marketing surveillance of major haemorrhagic complications associated with DOAC. It takes part to the knowledge about the course of this severe event in emergencies. Careful awareness in risk benefit assessment, especially in elderly, is needed. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Bleeding from esophageal varices is a significant factor in mortality of patients with terminal liver cirrhosis. This complication is a major health problem for recipients on the list for liver transplant. In that regard, studying predictors of variceal bleeding episode is very important. Also, it is important to find the best survival predictor among prognostic scores. The aim of the study was to compare validity of prognostic scores in assessment of survival in hospital-treated patients after bleeding from esophageal varices, and to compare validity of baseline Child-Turcotte-Pugh (CTP) and Modul for End-stage Liver Disease (MELD) scores with CTP creatinine modified (CTP-crea) I and II scores in assessment of survival in patients within a long-term follow-up period after the episode of bleeding from esophageal varices. The study included a total of 126 patients suffering from terminal liver cirrhosis submited to testing CTP score score I and II, MELD score, MELD Na score, integrated MELD score, MELD sodium (MESO) index, United Kingdom Model for End-Stage Liver Disease (UKELD) score and updated MELD score. Patients with bleeding from esophageal varices most often had CTP score rank C (46,9%). CTP score rank B had 37.5% patients, while the smallest percentage of patients had CTP rank A, 15.6% of them. Patients who have values of CTP score higher than 10.50 and bleeding from esophagus, have 3.2 times higher chance for death outcome compared to other patients. Patients who have values of CTP-crea I score higher than 10.50 and bleeding from esophagus, have 3.1 times higher chance for death out-come than other patients. Patients who have values of CTP-crea II score higher than 11.50 and bleeding from esophagus, have 3,7 times higher chance for death outcome compared to other patients. Survival of patients with bleeding from esophageal varices in the short-term follow up can be predicted by following CTP score and creatinine modified CTP scores. Patients with bleeding

    To determine the risk factors for severe postpartum haemorrhage. A case control study. Mulago hospital labour wards, Kampala, Uganda. One hundred and six mothers with severe postpartum haemorrhage were recruited between 15th November 2001 and 30th November 2002 and were compared with 500 women who had normal delivery. The predictors for postpartum haemorrhage were co-existing hypertension (O.R 9.3, 95% CI: 1.7-51.7), chronic anaemia (OR 17.3, 95% CI: 9.5-31.7), low socio economic background (OR 5.3, 95% CI: 3.0, 9.2), past history of postpartum haemorrhage (OR 3.6, 95% CI: 1.1-11.8), previous delivery by Caesarean section (OR 7.5, 95% CI: 3.5-14.3), long birth interval of more than sixty months (OR 5.2, 95% CI: 2.1-13.0), prolonged third stage (OR 49.1, 95% CI: 8.8-342.8) and non use of oxytocics (OR 4.3%, 95% CI: 1.2-15.3). Severe postpartum haemorrhage is common in our environment and is associated with a high maternal morbidity and mortality. The determinants of postpartum haemorrhage are useful in identifying mothers at risk and together with the services of a skilled birth attendant at delivery will prevent postpartum haemorrhage and reduce the maternal morbidity and mortality associated with this condition. In our study, the following risk factors were identified: pre-existing hypertension, chronic anaemia, low socio-economic background, history of postpartum haemorrhage, previous delivery by Caesarean section, longbirth interval of more than sixty months, prolonged third stage and non use of oxytocics were found to be significant.

    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.

    The use of intravenous thrombolytic agents has revolutionised the treatment of acute myocardial infarction. However, the improvement in mortality rate achieved with these drugs is tempered by the risk of serious bleeding complications, including intracranial haemorrhage. Tenecteplase is a genetically engineered mutant tissue plasminogen activator. Haemorrhagic complications of tissue plasminogen activator (tPA) are well known. Compared to other tPAs, tenecteplase use leads to lower rates of bleeding complications. Here, we report a case of unusual site of spontaneous bleeding, intralingual haematoma during tenecteplase therapy following acute myocardial infarction, which caused significant upper airway obstruction and required tracheotomy to maintain the patient's airway. Clinical dilemmas related to securing the airway or reversing the effects of tissue plasminogen activator are discussed. PMID:23862086

    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

    Nail haemorrhages are of interest to the chest physician and cardiologist. While the common type in the distal part of the nail is produced by the minor trauma of daily life, the rarer form—scattered through the nail substance—appears to be related to hypoxaemia brought about by heart and lung disease. We thought it would be of interest to study a population which was naturally hypoxaemic because of living at high altitude. Accordingly we have studied the frequency and types of nail haemorrhage in Quechua Indians who are permanently exposed to the hypobaric hypoxia of the Andes. We found the haemorrhages to be common both in mestizos living on the coastal plain and in the native highlanders. They appeared to increase in frequency with altitude but were of the distal type and would thus seem to be the result of minor trauma as at sea level. However, just as in cases of cyanotic congenital heart disease at low altitude, those with exaggerated hypoxaemia and pronounced elevation of haematocrit—namely, subjects with Monge's disease (chronic mountain sickness)—had scattered haemorrhages in the nail substance.

    Subungual haemorrhages are characterized by well-circumscribed dots or blotches with a red to red-black pigmentation, but some cases can be difficult to distinguish from subungual melanoma by the naked eye alone. Dermoscopy has proven to be a useful, noninvasive tool in the diagnosis of pigmented lesions in the nail; however, few dermoscopic studies of subungual haemorrhages have been reported. To investigate characteristic dermoscopic patterns of subungual haemorrhages, and to find distinctive features that can differentiate them from nail-unit melanomas. Patients with a confirmed diagnosis of either subungual haemorrhage or nail-unit melanoma at a tertiary university hospital were included in the study. Clinical features and dermoscopic patterns were evaluated. Sixty-four patients with a total of 90 lesions of subungual haemorrhage were enrolled in the study. The majority of cases (84%) showed combinations of more than one colour, while 16% had only one colour. The most common colour of the subungual haemorrhages was purple-black, in 37% of cases. A homogeneous pattern was observed in 92% of cases, globular patterns in 42% and streaks in 39%. Peripheral fading and periungual haemorrhages were found in 54% and 22% of cases, respectively. Destruction or dystrophy of the nail plate was observed in 16% of cases. In the 16 cases of nail-unit melanomas, Hutchinson sign, longitudinal irregular bands or lines, triangular shape of bands, vascular pattern, and ulcerations were found in 100%, 81%, 25%, 6% and 81% of cases, respectively. In contrast, these features were not found in subungual haemorrhages. Dermoscopy provides valuable information for the diagnosis of subungual haemorrhage and aids in the differential diagnosis from nail-unit melanoma. © 2013 The Authors.

To determine the percentage of parents able to recognise a haemorrhagic rash and perform the tumbler test. 123 parents of children consulting for mild injuries were interviewed about the significance and recognition of haemorrhagic rash in febrile children. Although 88% of parents undressed their children when they were febrile, it was never to look specifically for a skin rash. Only 7% (95% CI 3% to 12%) were able to recognise a petechial rash and knew the tumbler test. Information campaigns about the significance of haemorrhagic rash and about the tumbler test are needed.

    This study examined the extent of liver perfusion and its oxygenation during progressive haemorrhage. We examined hepatic arterial flow and hepatic oxygenation following the reduced portal flow during haemorrhage in 18 pigs. The hepatic surface oxygenation was assessed by near-infrared spectroscopy and the hepatic metabolism of oxygen, lactate and catecholamines determined the adequacy of the hepatic flow. Stepwise haemorrhage until circulatory collapse resulted in proportional reductions in cardiac output and in arterial, central venous and pulmonary wedge pressures. While heart rate increased, pulmonary arterial pressure remained stable. In addition, renal blood flow decreased, renal vascular resistance increased and there was elevated noradrenaline spill-over. Further, renal surface oxygenation was lowered from the onset of haemorrhage. Similarly, the portal blood flow was reduced in response to haemorrhage, and, as for the renal flow, the reduced splanchnic blood flow was associated with an elevated noradrenaline spill-over. In contrast, hepatic arterial blood flow was only slightly reduced by haemorrhage, and surface oxygenation did not change. The hepatic oxygen uptake was maintained until the blood loss represented more than 30 % of the estimated blood volume. At 30 % reduced blood volume, hepatic catecholamine uptake was reduced, and the lactate uptake approached zero. Subsequent reduction of cardiac output and portal blood flow elicited a selective dilatation of the hepatic arterial vascular bed. Due to this dilatation liver blood flow and hepatic cell oxygenation and metabolism were preserved prior to circulatory collapse. PMID:10087351

    Endoscopic band ligation is the treatment of choice for bleeding esophageal varices. However it is not clear if this procedure is associated with less early and late mortality than sclerotherapy. To assess rates of re-bleeding and mortality in cohorts of patients with bleeding esophageal varices treated with endoscopic injection or band ligation. Analysis of medical records and endoscopy reports of two cohorts of patients with bleeding esophageal varices, treated between 1990 and 2010. Of these, 54 patients were treated with sclerotherapy and 90 patients with band ligation. A third cohort of 116 patients that did not require endoscopic treatment, was included. The mean analyzed follow up period was 2.5 years (range 1-16). Collection of data was retrospective for patients treated with sclerotherapy and prospective for patients treated with band ligation. Rates of re-bleeding and medium term mortality were assessed. During the month ensuing the first endoscopic treatment, re-bleeding was recorded in 39 and 72% of patients treated with band ligation and sclerotherapy, respectively (p < 0.01). The relative risk of bleeding after band ligation was 0.53 (95% confidence limits 0.390.73). Death rates until the end of follow up were 20 and 48% among patients with treated with band ligation and sclerotherapy, respectively (p < 0.01), with a relative risk of dying for patients subjected to band ligation of 0.41 (95% confidence limits 0.25-0.68). Band ligation was associated with lower rates of re-bleeding and mortality in these cohorts of patients.

    Background: To highlight the problems of diagnosis and management of acute abdomen in patients with lassa fever. And to also highlight the need for high index of suspicion of lassa fever in patients presenting with acute abdominal pain in order to avoid surgical intervention with unfavourable prognosis and nosocomial transmission of infections, especially in Lassa fever-endemic regions. Materials and Methods: A review of experiences of the authors in the management of lassa fever over a 4-year period (2004-2008). Literature on lassa fever, available in the internet and other local sources, was studied in November 2010 and reviewed. Results: Normal plain chest radiographic picture can change rapidly due to pulmonary oedema, pulmonary haemorrhage and acute respiratory distress syndrome. Plain abdominal radiograph may show dilated bowels with signs of paralytic ileus or dynamic intestinal obstruction due to bowel wall haemorrhage or inflamed and enlarged Peyer's patches. Ultrasound may show free intra-peritoneal fluid due to peritonitis and intra-peritoneal haemorrhage. Bleeding into the gall bladder wall may erroneously suggest infective cholecystitis. Pericardial effusion with or without pericarditis causing abdominal pain may be seen using echocardiography. High index of suspicion, antibody testing for lassa fever and viral isolation in a reference laboratory are critical for accurate diagnosis. Conclusion: Patients from lassa fever-endemic regions may present with features that suggest acute abdomen. Radiological studies may show findings that suggest acute abdomen but these should be interpreted in the light of the general clinical condition of the patient. It is necessary to know that acute abdominal pain and vomiting in lassa fever-endemic areas could be caused by lassa fever, which is a medical condition. Surgical option should be undertaken with restraint as it increases the morbidity, may worsen the prognosis and increase the risk of nosocomial transmission

    A 48-year-old woman with alcoholic liver cirrhosis was admitted to our hospital because of hematochezia and severe anemia. She had been hospitalized many times over the past year for hematochezia of unknown etiology. Contrast-enhanced CT demonstrated ileal varices, which were fed by several ileal veins. These feeding veins were selectively embolized with N-butyl cyanoacrylate (NBCA) via a recanalized paraumbilical vein. The paraumbilical vein instead of the portal vein was punctured to decrease the risk of bleeding complications because she had coagulopathy and ascites. We consider antegrade embolization of ileal varices with NBCA to be a feasible and effective treatment. Access via a paraumbilical vein is an alternative to the transhepatic approach.Level of Evidence Level V, case report.

    This article aims to review current therapeutic endoscopic treatments available for the management of gastrointestinal bleeding related to cirrhosis. Endoscopic band ligation is an effective treatment for primary prophylaxis, acute bleeding, and secondary prophylaxis of esophageal varices as well as for acute bleeding and secondary prophylaxis of select gastric varices. Sclerotherapy is a treatment option for acute bleeding and secondary prophylaxis of esophageal varices when band ligation is technically difficult. Cyanoacrylate glue injection is an effective treatment for acute bleeding of gastric and ectopic varices. Argon plasma coagulation is first-line and radiofrequency ablation is second-line treatment for chronic bleeding secondary to gastric antral vascular ectasia. There are a variety of endoscopic treatment modalities for cirrhosis-related gastrointestinal bleeding, and the appropriate therapy depends on the location of the bleed, history or presence of acute bleeding, and risk factors for intervention-related adverse events.

    Portal hypertension is a severe syndrome that may derive from pre-sinusoidal, sinusoidal and post-sinusoidal causes. As a consequence, several complications (i.e., ascites, oesophageal varices) may develop. In sinusoidal portal hypertension, hepatic venous pressure gradient (HVPG) is a reliable method for defining the grade of portal pressure, establishing the effectiveness of the treatment and predicting the occurrence of complications; however, some questions exist regarding its ability to discriminate bleeding from nonbleeding varices in cirrhotic patients. Other imaging techniques (transient elastography, endoscopy, endosonography and duplex Doppler sonography) for assessing causes and complications of portal hypertensive syndrome are available and may be valuable for the management of these patients. In this review, we evaluate invasive and non-invasive techniques currently employed to obtain a clinical prediction of deadly complications, such as variceal bleeding in patients affected by sinusoidal portal hypertension, in order to create a diagnostic algorithm to manage them. Again, HVPG appears to be the reference standard to evaluate portal hypertension and monitor the response to treatment, but its ability to predict several complications and support management decisions might be further improved through the diagnostic combination with other imaging techniques.

In sinusoidal portal hypertension, hepatic venous pressure gradient (HVPG) is a reliable method for defining the grade of portal pressure, establishing the effectiveness of the treatment, and predicting the occurrence of complications; however, some questions exist regarding its ability to discriminate bleeding from non-bleeding varices in cirrhotic patients. Other imaging techniques (transient elastography, endoscopy, endosonography, and duplex Doppler sonography) for assessing causes and complications of portal hypertensive syndrome are available and may be valuable for the management of these patients. In this review, we evaluate invasive and non-invasive techniques currently employed to obtain a clinical prediction of deadly complications, such as variceal bleeding in patients affected by sinusoidal portal hypertension, in order to create a diagnostic algorithm to manage them. Again, HVPG appears to be the reference standard to evaluate portal hypertension and monitor the response to treatment, but its ability to predict several complications and support management decisions might be further improved through the diagnostic combination with other imaging techniques.

    Crimean-Congo haemorrhagic fever virus (CCHFV) is a member of the Orthonairovirus genus of the Nairoviridae family and is associated with haemorrhagic fever in humans. Although T lymphocyte responses are known to play a role in protection from and clearance of viral infections, specific T cell epitopes have yet to be identified for CCHFV following infection. A panel of overlapping peptides covering the CCHFV nucleoprotein and the structural glycoproteins, GN and GC, were screened by ELISpot assay to detect interferon gamma (IFN-γ) production in vitro by peripheral blood mononuclear cells from eleven survivors with previous laboratory confirmed CCHFV infection. Reactive peptides were located predominantly on the nucleoprotein, with only one survivor reacting to two peptides from the glycoprotein GC. No single epitope was immunodominant, however all but one survivor showed reactivity to at least one T cell epitope. The responses were present at high frequency and detectable several years after the acute infection despite the absence of continued antigenic stimulation. T cell depletion studies confirmed that IFN-γ production as detected using the ELISpot assay was mediated chiefly by CD8+ T cells. This is the first description of CD8+ T cell epitopic regions for CCHFV and provides confirmation of long-lived T cell responses in survivors of CCHFV infection. PMID:29261651

    The EEA stapler has been used routinely for esophageal transection to treat esophageal variceal bleeding for some time. It carries the risk of postoperative leakage and is not suitable in those cases receiving recent sclerotherapy. The circumferential suture technique presented in this paper can be used in any situation requiring esophageal transection. It has been utilized by us in twenty-two emergent cases with good results.

    The aim of this study was to evaluate a possible relationship between lunar cycles and haemorrhagic complication rate in surgery. The possible relationship between moon phases and surgical outcome was tested by evaluating the haemorrhagic complication rate for 18,760 patients who underwent surgery between January 2001 and December 2008 at the National Institute for Cancer Research in Genoa. A total of 103 lunar phases were considered using Chi-square (χ 2 ) test analysis, and patients were allocated a surgery date. One hundred and sixty-seven haemorrhagic complications were observed. Three hundred and nine new moon phase days were analysed and 12 incidences of complications detected, with a 3.9% complication rate per day. In the waxing moon phase, 1184.5 d were analysed with 68 incidences of complications at a daily rate of 5.7%. In the full moon phase there was a 4.9% complication rate per day (15 incidences in 309 d), whereas in the waning moon phase, the 6% percentage rate per day resulted from 72 incidences in 1184.5 d. No statistically significant correlations were found between moon cycles and postoperative haemorrhagic complications (p = .50).

    Over 2 million people are affected by intracerebral haemorrhage (ICH) worldwide every year, one third of them dying within 1 month, and many survivors being left with permanent disability. Unlike most other stroke types, the incidence, morbidity and mortality of ICH have not declined over time. No standardised diagnostic workup for the detection of the various underlying causes of ICH currently exists, and the evidence for medical or surgical therapeutic interventions remains limited. A dedicated European research programme for ICH is needed to identify ways to reduce the burden of ICH-related death and disability. The European Research Network on Intracerebral Haemorrhage EURONICH is a multidisciplinary academic research collaboration that has been established to define current research priorities and to conduct large clinical studies on all aspects of ICH.

    Admission blood glucose is known to be a predictor for outcome in several disease patterns, especially in critically ill trauma patients. The underlying mechanisms for the association of hyperglycaemia and poor outcome are still not proven. It was hypothesised that hyperglycaemia upon hospital admission is associated with haemorrhagic shock and in-hospital mortality. Data was extracted from an observational trauma database of the level 1 trauma centre at Innsbruck Medical University hospital. Trauma patients (≥18 years) with multiple injuries and an Injury Severity Score ≥17 were included and analysed. In total, 279 patients were analysed, of which 42 patients (15.1%) died. With increasing blood glucose upon hospital admission, the rate of patients with haemorrhagic shock rose significantly [from 4.4% (glucose 4.1-5.5mmol/L) to 87.5% (glucose >15mmol/L), p<0.0001]. Mortality was also associated with initial blood glucose [≤5.50mmol/L 8.3%; 5.51-7.50mmol/L 10.9%, 7.51-10mmol/L 12.4%; 10.01-15mmol/L 32.0%; ≥15.01mmol/L 12.5%, p=0.008]. Admission blood glucose was a better indicator for haemorrhagic shock (cut-off 9.4mmol/L, sensitivity 67.1%, specificity 83.9%) than haemoglobin, base excess, bicarbonate, pH, lactate, or vital parameters. Regarding haemorrhagic shock, admission blood glucose is more valuable during initial patient assessment than the second best predictive parameter, which was admission haemoglobin (cut-off value 6.5mmol/L (10.4g/dL): sensitivity 61.3%, specificity 83.9%). In multiple trauma, non-diabetic patients, admission blood glucose predicted the incidence of haemorrhagic shock. Admission blood glucose is an inexpensive, rapidly and easily available laboratory value that might help to identify patients at risk for haemorrhagic shock during initial evaluation upon hospital admission.

    Varicose veins (VVs) and varicose ulceration (VU) are usually considered non-life-threatening conditions, but in some cases they can lead to major complications such as fatal bleeding. The aim of this systematic review is to evidence the most updated information on bleeding from VV and VU. As evidence acquisition, we planned to include all the studies dealing with "Haemorrhage/Bleeding" and "VVs/VU". We excluded all the studies, which did not properly fit our research question, and with insufficient data. As evidence synthesis, of the 172 records found, after removing of duplicates, and after records excluded in title and abstract, 85 matched our inclusion criteria. After reading the full-text articles, we decided to exclude 68 articles because of the following reasons: (1) not responding properly to our research questions; (2) insufficient data; the final set included 17 articles. From literature searching, we identify the following main issues to be discussed in the review: epidemiology and predisposing factors, pathophysiology and forensic aspects, first aid. It has been estimated that deaths for bleeding due to peripheral venous problems account up to 0.01% of autopsy cases. From a pathological point of view, venous bleeding may arise from either acute or chronic perforation of an enlarged vein segment through the weakened skin. From a forensic point of view, in cases of fatal haemorrhage the death scene can even simulate non-natural events, due to crime or suicide. In most cases, incorrect first aid led to fatal complications. Further investigation on epidemiology and prevention measures are needed. © 2018 Medicalhelplines.com Inc and John Wiley & Sons Ltd.

    Higher body temperature is a prognostic factor of poor outcome in acute stroke. Our aim was to study the relationship between body temperature, HT (haemorrhagic transformation) and biomarkers of BBB (blood-brain barrier) damage in patients with acute ischaemic stroke untreated with rtPA (recombinant tissue-type plasminogen activator). We studied 229 patients with ischaemic stroke <12 h from symptom onset. Body temperature was determined at admission and every 6 h during the first 3 days. HT was evaluated according to ECASS II (second European Co-operative Acute Stroke Study) criteria in a multimodal MRI (magnetic resonance imaging) at 72 h. We found that 55 patients (34.1%) showed HT. HT was associated with cardioembolic stroke (64.2% against 23.0%; P<0.0001), higher body temperature during the first 24 h (36.9°C compared with 36.5°C; P<0.0001), more severe stroke [NIHSS (National Institutes of Health Stroke Scale) score, 14 (9-20) against 10 (7-15); P=0.002], and greater DWI (diffusion-weighted imaging) lesion volume at admission (23.2 cc compared with 13.2 cc; P<0.0001). Plasma MMP-9 (matrix metalloproteinase 9) (187.3 ng/ml compared with 44.2 ng/ml; P<0.0001) and cFn (cellular fibronectin) levels (16.3 μg/ml compared with 7.1 μg/ml; P=0.001) were higher in patients with HT. Body temperature within the first 24 h was independently associated with HT {OR (odds ratio), 7.3 [95% CI (confidence interval), 2.4-22.6]; P<0.0001} after adjustment for cardioembolic stroke subtype, baseline NIHSS score and DWI lesion volume. This effect remained unchanged after controlling for MMP-9 and cFn. In conclusion, high body temperature within the first 24 h after ischaemic stroke is a risk factor for HT in patients untreated with rtPA. This effect is independent of some biological signatures of BBB damage.

    Japan Gastroenterological Endoscopy Society (JGES) has compiled a set of guidelines for endoscopic management of non-variceal upper gastrointestinal bleeding using evidence-based methods. The major cause of non-variceal upper gastrointestinal bleeding is peptic gastroduodenal ulcer bleeding. As a result, these guidelines mainly focus on peptic gastroduodenal ulcer bleeding, although bleeding from other causes is also overviewed. From the epidemiological aspect, in recent years in Japan, bleeding from drug-related ulcers has become predominant in comparison with bleeding from Helicobacter pylori (HP)-related ulcers, owing to an increase in the aging population and coverage of HP eradication therapy by national health insurance. As for treatment, endoscopic hemostasis, in which there are a variety of methods, is considered to be the first-line treatment for bleeding from almost all causes. It is very important to precisely evaluate the severity of the patient's condition and stabilize the patient's vital signs with intensive care for successful endoscopic hemostasis. Additionally, use of antisecretory agents is recommended to prevent rebleeding after endoscopic hemostasis, especially for gastroduodenal ulcer bleeding. Eighteen statements with evidence and recommendation levels have been made by the JGES committee of these guidelines according to evidence obtained from clinical research studies. However, some of the statements that are supported by a low level of evidence must be confirmed by further clinical research. © 2016 Japan Gastroenterological Endoscopy Society.

    Endoscopic injection of N-butyl-2-cyanoacrylate is the current recommended treatment for gastric variceal bleeding. Despite the extensive worldwide use, there are still differences related to the technique, safety, and long term-results. We retrospectively evaluated the efficacy and safety of cyanoacrylate in patients with gastric variceal bleeding. Between January 1998 and January 2010, 97 patients with gastric variceal bleeding underwent endoscopic treatment with a mixture of N-butyl-2-cyanoacrylate and Lipiodol(TM). Ninety-one patients had cirrhosis and 6 had non-cirrhotic portal hypertension. Child-Pugh score at presentation for cirrhotic patients was A-12.1 %; B-53.8 %; C-34.1 % and median MELD score at admission was 13 (3-26). Successful hemostasis, rebleeding rate and complications were reviewed. Median time of follow up was 19 months (0.5-126). A median mixture volume of 1.5 mL (0.6 to 5 mL), in 1 to 8 injections, was used, with immediate hemostasis rate of 95.9 % and early rebleeding rate of 14.4 %. One or more complications occurred in 17.5 % and were associated with the use of Sengstaken-Blakemore tube before cyanoacrylate and very early rebleeding (p < 0.05). Hospital mortality rate during initial bleeding episode was 9.3 %. Very early rebleeding was a strong and independent predictor for in-hospital mortality (p < 0.001). Long-term mortality rate was 58.8 %, in most of the cases secondary to hepatic failure. N-butyl-2-cyanoacrylate is a rapid, easy and highly effective modality for immediate hemostasis of gastric variceal bleeding with an acceptable rebleeding rate. Patients with very early rebleeding are at higher risk of death.

    Secondary ischaemia is a frequent cause of poor outcome in patients with aneurysmal subarachnoid haemorrhage (SAH). Besides vasospasm, platelet aggregation seems to play a role in the pathogenesis of secondary ischaemia. Experimental studies have suggested that antiplatelet agents can prevent secondary ischaemia. To determine whether antiplatelet agents change outcome in patients with aneurysmal SAH. We searched the Cochrane Stroke Group Trials Register (last searched August 2006), MEDLINE (1966 to August 2006) and EMBASE databases (1980 to August 2006). We also searched reference lists of identified trials. All randomised controlled trials (RCTs) comparing any antiplatelet agent with control in patients with aneurysmal SAH. Two review authors independently extracted the data and assessed trial quality. Relative risks (RR) were calculated with regard to poor outcome, case fatality, secondary ischaemia, haemorrhagic intracranial complications and aneurysmal rebleeding according to the intention-to-treat principle. In case of a statistically significant primary analysis, a worst case analysis was performed. Seven RCTs were included in the review, totalling 1385 patients. Four of these trials met the criteria for good quality studies. For any antiplatelet agent there were reductions of a poor outcome (RR 0.79, 95% confidence interval (CI) 0.62 to 1.01) and secondary brain ischaemia (RR 0.79, 95% CI 0.56 to 1.22) and more intracranial haemorrhagic complications (RR 1.36, 95% CI 0.59 to 3.12), but none of these differences were statistically significant. There was no effect on case fatality (RR 1.01, 95% CI 0.74 to 1.37) or aneurysmal rebleeding (RR 0.98, 95% CI 0.78 to 1.38). For individual antiplatelet agents, only ticlopidine was associated with statistically significant fewer occurrences of a poor outcome (RR 0.37, 95% CI 95% CI 0.14 to 0.98) but this estimate was based on only one small RCT. This review shows a trend towards better outcome in patients treated with

    As a result of this retrospective analysis of hemorrhage from a porta-systemic venous shunt occurring within the small intestine, we believe that the early diagnosis of the syndrome is strongly suggested by the presence of varices in unusual locations demonstrated by the venous phase of mesenteric arteriography. In all patients portal hypertension was present, and in all the affected bowel was adherent to postoperative adhesions on old suture lines. The syndrome was treated variously with lysis of adhesions, bowel resection, or portal-systemic shunt. Those patients with excellent hepatic reserve survived and had no further gastrointestinal bleeding. Images Fig. 1a. Fig. 1b. Fig. 1c. Fig. 2. Fig. 3. Fig. 4a. Fig. 4b. Fig. 5. PMID:1082310

    We aimed to validate a previously described six simple variable (SSV) model that was developed from acute and sub-acute stroke patients in our population that included hyper-acute stroke patients. A Stroke Outcome Study enrolled patients from 2001 to 2002. Functional status was assessed at 6 months using the modified Rankin Scale (mRS). SSV model performance was tested in our cohort. 538 acute ischaemic (87%) and haemorrhagic stroke patients were enrolled, 51% of whom presented to hospital within 6 h of symptom recognition. At 6 months post-stroke, 42% of patients had a good outcome (mRS < or = 2). Stroke patients presenting within 6 h of symptom recognition were significantly older with higher stroke severity. In our Stroke Outcome Study dataset, the SSV model had an area under the curve of 0.792 for 6 month outcomes and performed well for hyper-acute or post-acute stroke, age < or > or = 75 years, haemorrhagic or ischaemic stroke, men or women, moderate and severe stroke, but poorly for mild stroke. This study confirms the external validity of the SSV model in our hospital stroke population. This model can therefore be utilised for stratification in acute and hyper-acute stroke trials.

    Although an association between clostridial pathogens and canine idiopathic acute haemorrhagic diarrhoea syndrome (AHDS) has been described, the relevance of those bacteria and their toxins remains unclear. The aim of this study was to evaluate the association between severity of clinical signs and presence of Clostridium perfringens enterotoxin (CPE) and Clostridium difficile toxin A/B (CDT A/B) in faeces of dogs with AHDS. Faecal samples of 54 dogs with idiopathic AHDS were tested by qualitative CPE and CDT A/B ELISA, and PCR was performed to detect enterotoxin genes of C. perfringens (cpe) and toxin B genes of C. difficile (cdt b). Prevalence of cdt b and CDT A/B in dogs with AHDS was 10/54 and 2/54 versus 3/23 and 0/23 in control dogs. Prevalence of cpe was 35/54 in affected versus 9/23 in control dogs. Prevalence of CPE in dogs with AHDS (13/54) was higher compared with control dogs (0/23). No significant difference was detected between CPE-positive and -negative and between cpe-positive and -negative dogs in severity of clinical signs, duration of hospitalisation, mortality rate and selected laboratory parameters. This study suggests that CPE and CDT A/B do not play a role in idiopathic AHDS, are not associated with clinical parameters in affected dogs and cannot be used to predict disease outcome.

    Determine the optimal scoring system for evaluation of 6-week bleeding-related mortality in liver cirrhosis patients with acute variceal bleeding (AVB). Prediction effects of six scoring systems, AIMS65 score, Glasgow-Blatchford (GBS) score, full Rockall (FRS) score, the model for end-stage liver disease (MELD), the MELD-Na model and the Child-Turcotte-Pugh (CTP) score were analyzed in this study. A total of 202 liver cirrhosis patients with AVB were enrolled between 1 January 2014, and 31 December 2014. All subjects were scored according to AIMS65, GBS, FRS, MELD, MELD-Na and CTP scoring systems on the first day of admission. The primary endpoint of the study was 6-week mortality. The prediction effect of these scoring systems for 6-week mortality was compared by ROC curve and the area under the curve (AUC). The scores of nonsurvival group evaluated by the AIMS65, GBS, FRS, MELD, MELD-Na and CTP (2.6 ± 1.1, 12.9 ± 2.7, 6.6 ± 1.8, 26.9 ± 6.5, 31.6 ± 9.3, 9.6 ± 2.2, respectively) were higher than those of the survival group (1.2 ± 1.1, 10.2 ± 3.4, 5.1 ± 1.6, 21.0 ± 6.4, 22.8 ± 8.2, 7.7 ± 2.0, respectively) (p < .01). The values of AUC and Youden index of AIMS65 and MELD-Na scoring systems [(0.808, 0.453) and (0.781, 0.516), respectively] were superior to those of MELD (0.761, 0.454), CTP (0.748, 0.399), FRS (0.738, 0.358) and GBS scoring systems (0.726, 0.370). AIMS65 and MELD-Na scoring systems are recommended for evaluation of 6-week bleeding-related mortality in liver cirrhosis patients with AVB.

    To compare the impact of low-grade haemorrhage on neurocognitive function in 16-year-old adolescents born preterm, by grade of intraventricular haemorrhage, and term controls. We evaluated 338 preterm adolescents (birth weight 600-1250 g) for intelligence, executive function and memory tasks. Eleven had grade 3-4 haemorrhage, 44 had grade 2, 31 had grade 1, and 251 had no haemorrhage. Group comparisons were made with 102 term age-matched controls, and regression models used to identify the risk that low-grade haemorrhage posed for cognitive, executive function and memory deficits. Preterm adolescents with grade 2 haemorrhage had higher deficit rates of verbal intelligence, receptive vocabulary, phonemic fluency, cognitive flexibility and phonological fluency than preterm adolescents with grade 1 or no haemorrhage, compared with term controls. After excluding preterm adolescents with both grade 2 haemorrhage and cystic periventricular leukomalacia, those with isolated grade 2 haemorrhage remained at greater risk of cognitive and executive function deficits than term controls and of cognitive deficits than preterm adolescents with no haemorrhage. Our findings suggest that preterm adolescents born in the early 1990s with isolated grade 2 haemorrhage are at increased risk of learning challenges, including cognitive and executive function deficits. ©2014 Foundation Acta Paediatrica.

    The aim of the study is to describe the epidemiology of major bleeding fatalities. A case series analysis of Australia's National Coronial Information System was conducted. Keywords were used to search for closed cases of major haemorrhage in the state of Victoria for the period 1 January 2009 to 31 December 2011. Coroners' findings, autopsy reports and police reports of cases were reviewed. Demographic data were extracted, and cases were assigned to a clinical bleeding context. A total of 427 cases of major bleeding causing death were identified. The cohort was predominately men (69%), with a median age of 63 years (interquartile range 45-77 years). Trauma accounted for 38%, gastrointestinal haemorrhage 28%, surgical/procedural bleeding 14%, ruptured/leaking aneurysms 12% and other 8%. Most events began in homes (46%), hospitals (22%) and at the roadside (17%). Of those whose haemorrhage began in the community, 69% did not survive to hospital. Major bleeding fatalities occurred across a diverse range of contexts, with trauma and gastrointestinal bleeding accounting for most deaths. The majority of patients did not survive to reach hospital. Major haemorrhage occurring entirely outside hospital may be underrecognised from analyses of datasets based primarily on traumatic or in-hospital bleeding. These findings have implications for management of pre-hospital resuscitation and development of clinical practice guidelines for identification and management of major bleeding in the community. © 2017 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

    To examine whether interprofessional simulation training on management of postpartum haemorrhage enhances self-efficacy and collective efficacy and reduces the blood transfusion rate after birth. Postpartum haemorrhage is a leading cause of maternal morbidity and mortality worldwide, although it is preventable in most cases. Interprofessional simulation training might help improve the competence of health professionals dealing with postpartum haemorrhage, and more information is needed to determine its potential. Multimethod, quasi-experimental, pre-post intervention design. Interprofessional simulation training on postpartum haemorrhage was implemented for midwives, obstetricians and auxiliary nurses in a university hospital. Training included realistic scenarios and debriefing, and a measurement scale for perceived postpartum haemorrhage-specific self-efficacy, and collective efficacy was developed and implemented. Red blood cell transfusion was used as the dependent variable for improved patient outcome pre-post intervention. Self-efficacy and collective efficacy levels were significantly increased after training. The overall red blood cell transfusion rate did not change, but there was a significant reduction in the use of ≥5 units of blood products related to severe bleeding after birth. The study contributes to new knowledge on how simulation training through mastery and vicarious experiences, verbal persuasion and psychophysiological state might enhance postpartum haemorrhage-specific self-efficacy and collective efficacy levels and thereby predict team performance. The significant reduction in severe postpartum haemorrhage after training, indicated by reduction in ≥5 units of blood transfusions, corresponds well with the improvement in collective efficacy, and might reflect the emphasis on collective efforts to counteract severe cases of postpartum haemorrhage. Interprofessional simulation training in teams may contribute to enhanced prevention and

    The cardiovascular effects of the opioid mixed agonist-antagonist, meptazinol, and the opioid antagonist, naloxone, have been evaluated in conscious rats, anaesthetized rats and anaesthetized cats following the induction of haemorrhagic shock. The mean arterial pressure of conscious rats decreased by 17-29 mmHg following a haemorrhage of 20% of blood volume. Meptazinol (17 mg kg-1, i.m.) administered after haemorrhage evoked a rapid and sustained increase in mean arterial pressure to pre-haemorrhage levels. Naloxone (10 mg kg-1, i.v.) also increased mean arterial pressure to a level significantly higher than post-haemorrhage values. Neither haemorrhage nor subsequent drug treatments evoked significant changes in the heart rates of conscious rats. In anaesthetized rats, 20% haemorrhage evoked decreases in mean arterial pressure, heart rate and cardiac output. Blood flow to the heart, skin, skeletal muscle, kidneys, spleen and liver (arterial) was decreased. Meptazinol and naloxone increased blood pressure and total peripheral resistance, but did not significantly alter heart rate or cardiac output. Hepatic arterial flow decreased further in both drug and vehicle treated groups. In addition meptazinol slightly reduced skeletal muscle flow. In anaesthetized cats 40% haemorrhage decreased mean arterial pressure by 46 +/- 3 mmHg. An intravenous infusion of either meptazinol or naloxone (cumulative 2 mg kg-1, i.v.) partially restored blood pressure. In experimental animal models of haemorrhagic shock, meptazinol has a similar cardiovascular profile to naloxone. The established analgesic activity of meptazinol may confer an advantage in some shock states. PMID:4052729

    Abstract Aspartate aminotransferase-to-platelet ratio (APRI), aspartate aminotransferase-to-alanine aminotransferase ratio (AAR), FIB-4, FI, King, Lok, Forns, and FibroIndex scores may be simple and convenient noninvasive diagnostic tests, because they are based on the regular laboratory tests and demographic data. This study aimed to systematically evaluate their diagnostic accuracy for the prediction of varices in liver cirrhosis. All relevant papers were searched via PubMed, EMBASE, CNKI, and Wanfang databases. The area under the summary receiver operating characteristic curve (AUSROC), sensitivity, specificity, positive and negative likelihood ratio (PLR and NLR), and diagnostic odds ratio (DOR) were calculated. Overall, 12, 4, 5, 0, 0, 4, 3, and 1 paper was identified to explore the diagnostic accuracy of APRI, AAR, FIB-4, FI, King, Lok, Forns, and FibroIndex scores, respectively. The AUSROCs of APRI, AAR, FIB-4, Lok, and Forns scores for the prediction of varices were 0.6774, 0.7275, 0.7755, 0.7885, and 0.7517, respectively; and those for the prediction of large varices were 0.7278, 0.7448, 0.7095, 0.7264, and 0.6530, respectively. The diagnostic threshold effects of FIB-4 and Forns scores for the prediction of varices were statistically significant. The sensitivities/specificities/PLRs/NLRs/DORs of APRI, AAR, and Lok scores for the prediction of varices were 0.60/0.67/1.77/0.58/3.13, 0.64/0.63/1.97/0.54/4.18, and 0.74/0.68/2.34/0.40/5.76, respectively. The sensitivities/specificities/PLRs/NLRs/DORs of APRI, AAR, FIB-4, Lok, and Forns scores for the prediction of large varices were 0.65/0.66/2.15/0.47/4.97, 0.68/0.58/2.07/0.54/3.93, 0.62/0.64/2.02/0.56/3.57, 0.78/0.63/2.09/0.37/5.55, and 0.65/0.61/1.62/0.59/2.75, respectively. APRI, AAR, FIB-4, Lok, and Forns scores had low to moderate diagnostic accuracy in predicting the presence of varices in liver cirrhosis. PMID:26496312

    Background: Renal impairment is regularly seen in hospitalized stroke patients, affecting the outcome of patients, as well as causing difficulties in their management. A prospective cohort study was conducted to assess the trend of renal function in hospitalized ischemic and haemorrhagic stroke patients. The incidence of renal impairment in these subgroups, the contributing factors and the need for renal replacement in renal impaired patients was evaluated. Methods: Alternate day renal function testing was performed in hospitalized stroke patients. Estimated glomerular filtration rate (e-GFR) was calculated and the trend of renal function in the two stroke subgroups (haemorrhagic and ischemic) was assessed, with renal impairment defined as e-GFR < 60mL/ minute per 1.73m 2 . Results: Among 52 patients, 25 had haemorrhagic stroke (mean age 59.81 ± 14.67) and 27 had ischemic stroke (mean age 56.12 ± 13.08). The mean e-GFR (mL/minute per 1.732m 2 ) at admission in the haemorrhagic stroke subgroup was 64.79 ± 25.85 compared to 86.04 ± 26.09 in the ischemic stroke subgroup (p=0.005). Sixteen out of 25 (64%) patients in the haemorrhagic stroke subgroup and 9 out of 27 (33.3%) patients in the ischemic subgroup developed renal impairment (p=0.027). The location of the bleed (p=0.8), volume of hematoma (p=0.966) and surgical intervention (p=0.4) did not predispose the patients to renal impairment. One out of 16 patients with haemorrhagic stroke (who eventually died), and 2 out of 9 patients with ischemic stroke required renal replacement. Conclusion : Renal impairment is commonly seen in stroke patients, more so in patients who suffered haemorrhagic strokes.  The impairment, however, is transient and rarely requires renal replacement therapy.

    We aimed to determine the rate of hospital readmission within 30 days of non-variceal upper gastrointestinal hemorrhage and its impact on mortality, morbidity, and health care use in the United States. We performed a retrospective study using the Agency for Healthcare Research and Quality's Healthcare Cost and Utilization Project Nationwide Readmission Database for the year 2014 (data on 14.9 million hospital stays at 2048 hospitals in 22 states). We collected data on hospital readmissions of 203,220 adults who were hospitalized for urgent non-variceal upper gastrointestinal hemorrhage and discharged. The primary outcome was rate of all-cause readmission within 30 days of discharge. Secondary outcomes were reasons for readmission, readmission mortality rate, morbidity (shock and prolonged mechanical ventilation) and resource use (length of stay and total hospitalization costs and charges). Independent risk factors for readmission were identified using Cox regression analysis. The 30-day rate of readmission was 13%. Only 18% of readmissions were due to recurrent non-variceal upper gastrointestinal bleeding. The rate of death among patients readmitted to the hospital (4.7%) was higher than that for index admissions (1.9%) (P < .01). A higher proportion of readmitted patients had morbidities requiring prolonged mechanical ventilation (1.5%) compared with index admissions (0.8%) (P < .01). A total of 133,368 hospital days was associated with readmission, and the total health care in-hospital economic burden was $30.3 million (in costs) and $108 million (in charges). Independent predictors of readmission were Medicaid insurance, higher Charlson comorbidity score, lower income, residence in a metropolitan area, hemorrhagic shock, and longer stays in the hospital. Older age, private or no insurance, upper endoscopy, and prolonged mechanical ventilation were associated with lower odds for readmission. In a retrospective study of patients hospitalized for non-variceal

    Background It is unclear whether an upper gastrointestinal bleed is an isolated gastrointestinal event or an indicator of a deterioration in a patient's overall health status. Therefore, we investigated the excess causes of death in individuals after a non-variceal bleed compared with deaths in a matched sample of the general population. Methods and Findings Linked longitudinal data from the English Hospital Episodes Statistics (HES) data, General Practice Research Database (GPRD), and Office of National Statistics death register were used to define a cohort of non-variceal bleeds between 1997 and 2010. Controls were matched at the start of the study by age, sex, practice, and year. The excess risk of each cause of death in the 5 years subsequent to a bleed was then calculated whilst adjusting for competing risks using cumulative incidence functions. 16,355 patients with a non-variceal upper gastrointestinal bleed were matched to 81,523 controls. The total 5-year risk of death due to gastrointestinal causes (malignant or non-malignant) ranged from 3.6% (≤50 years, 95% CI 3.0%–4.3%) to 15.2% (≥80 years, 14.2%–16.3%), representing an excess over controls of between 3.6% (3.0%–4.2%) and 13.4% (12.4%–14.5%), respectively. In contrast the total 5-year risk of death due to non-gastrointestinal causes ranged from 4.1% (≤50 years, 3.4%–4.8%) to 46.6% (≥80 years, 45.2%–48.1%), representing an excess over controls of between 3.8% (3.1%–4.5%) and 19.0% (17.5%–20.6%), respectively. The main limitation of this study was potential misclassification of the exposure and outcome; however, we sought to minimise this by using information derived across multiple linked datasets. Conclusions Deaths from all causes were increased following an upper gastrointestinal bleed compared to matched controls, and over half the excess risk of death was due to seemingly unrelated co-morbidity. A non-variceal bleed may therefore warrant a careful assessment of co

    Gastroesophageal varices are present in approximately 50% of patients with liver cirrhosis. The aim of this study was to evaluate liver stiffness measurement (LSM), Fib-4, Forns Index and Lok Score as noninvasive predictors of esophageal varices (EV). This prospective study included 65 patients with HCV-related liver cirrhosis. All patients underwent routine laboratory tests, transient elastograhy (TE) and esophagogastroduodenoscopy. FIB-4, Forns Index and Lok Score were calculated. The diagnostic performances of these methods were assessed using sensitivity, specificity, positive predictive value, negative predictive value, accuracy and receiver operating characteristic curves. All predictors (LSM, FIB-4, Forns Index and Lok Score) demonstrated statistically significant correlation with the presence and the grade of EV. TE could diagnose EV at a cutoff value of 18.2kPa. Fib-4, Forns Index, and Lok Score could diagnose EV at cutoff values of 2.8, 6.61 and 0.63, respectively. For prediction of large varices (grade 2, 3), LSM showed the highest accuracy (80%) with a cutoff of 22.4kPa and AUROC of 0.801. Its sensitivity was 84%, specificity 72%, PPV 84% and NPV 72%. The diagnostic accuracies of FIB-4, Forns Index and Lok Score were 70%, 70% and76%, respectively, at cutoffs of 3.3, 6.9 and 0.7, respectively. For diagnosis of large esophageal varices, adding TE to each of the other diagnostic indices (serum fibrosis scores) increased their sensitivities with little decrease in their specificities. Moreover, this combination decreased the LR- in all tests. Noninvasive predictors can restrict endoscopic screening. This is very important as non invasiveness is now a major goal in hepatology.

    AIM To investigate whether selective serotonin re-uptake inhibitor (SSRI) use is associated with an increased risk of haemorrhagic stroke in a cohort of antidepressant users. METHODS We conducted a case control study, nested within a cohort of antidepressant users in the United Kingdom General Practice Research Database. A cohort of 365 195 patients prescribed either an SSRI or tricyclic antidepressant between 1992 and 2006 was identified. Three hundred and fifty-seven cases of haemorrhagic stroke were observed and 1631 control patients without haemorrhagic stroke were selected. RESULTS The primary analysis showed no evidence of an association between current SSRI or TCA use and haemorrhagic stroke. Current use of an SSRI compared with no use at the time of haemorrhagic stroke was associated with an adjusted odds ratio of 1.11 (95% confidence interval (CI) 0.82, 1.50). For current tricyclic use the equivalent odds ratio was 0.73 (0.52, 1.02). There was no evidence that prior cerebrovascular events modified the effect of either SSRIs or TCAs. CONCLUSIONS We found no evidence that SSRIs are associated with an increased risk of haemorrhagic stroke, regardless of prior history of cerebrovascular events. PMID:21143507

    The aim of this study was to describe the prevalence, patterns of blood use and outcomes of major haemorrhage in trauma. This was a prospective observational study from 22 hospitals in the UK, including both major trauma centres and smaller trauma units. Eligible patients received at least 4 units of packed red blood cells (PRBCs) in the first 24 h of admission with activation of the massive haemorrhage protocol. Case notes, transfusion charts, blood bank records and copies of prescription/theatre charts were accessed and reviewed centrally. Study outcomes were: use of blood components, critical care during hospital stay, and mortality at 24 h, 30 days and 1 year. Data were used to estimate the national trauma haemorrhage incidence. A total of 442 patients were identified during a median enrolment interval of 20 (range 7-24) months. Based on this, the national incidence of trauma haemorrhage was estimated to be 83 per million. The median age of patients in the study cohort was 38 years and 73·8 per cent were men. The incidence of major haemorrhage increased markedly in patients aged over 65 years. Thirty-six deaths within 24 h of admission occurred within the first 3 h. At 24 h, 79 patients (17·9 per cent) had died, but mortality continued to rise even after discharge. Patients who received a cumulative ratio of fresh frozen plasma to PRBCs of at least 1 : 2 had lower rates of death than those who received a lower ratio. There were delays in administration of blood. Platelets and cryoprecipitate were either not given, or transfused well after initial resuscitation. There is a high burden of trauma haemorrhage that affects all age groups. Research is required to understand the reasons for death after the first 24 h and barriers to timely transfusion support. © 2016 BJS Society Ltd Published by John Wiley & Sons Ltd.

    Crimean-Congo haemorrhagic fever (CCHF) is one of the most widespread arboviroses in the world. It is present in Africa, south-east Europe, the Middle East and Asia. It is caused by a nairovirus (Bunyaviridae family) transmitted by several species of ticks. The geographical distribution of the disease coincides with the distribution of Hyalomma ticks. While infected livestock do not show signs of illness, humans are severely affected, with a high mortality rate. The most common symptoms are high fever, dizziness, headache, vomiting and haemorrhages. Pathogenesis studies in interferon-receptor-deficient mice indicated that the interferon response is crucial in controlling virus propagation and in protecting against the disease. Detection of the virus in biological material is currently performed by reverse-transcription polymerase chain reaction. Enzyme-linked immunosorbent assay and indirect immunofluorescence are used to detect the presence of CCHF virus-specific antibodies. In the 1970s, a formalin-inactivated vaccine prepared from suckling mouse brain was used in Eastern Europe and the former Soviet Union, but its efficacy remains to be proven. Treatment of patients with ribavirin is recommended by the World Health Organization, but it should be administered as early as possible. Although important progress has been made over the last few decades, many questions about the pathogenesis and epidemiology of the disease are still to be addressed and there is a need to develop efficient vaccines and antivirals.

    The increased mortality rates of survivors of aneurysmal subarachnoid haemorrhage have been attributed to an increased risk of cardiovascular events in a registry study in Sweden. Swedish registries have however not been validated for subarachnoid haemorrhage and Scandinavian incidences of cardiovascular disease differ from that in Western European countries. We assessed risks of vascular disease and death in subarachnoid haemorrhage survivors in the Netherlands. From the Dutch hospital discharge register, we identified all patients with subarachnoid haemorrhage admission between 1997 and 2008. We determined the accuracy of coding of the diagnosis subarachnoid haemorrhage for patients admitted to our centre. Conditional on survival of three-months after the subarachnoid haemorrhage, we calculated standardized incidence and mortality ratios for fatal or nonfatal vascular diseases, vascular death, and all-cause death. Cumulative risks were estimated with survival analysis. The diagnosis of nontraumatic subarachnoid haemorrhage was correct in 95·4% of 1472 patients. Of 11,263 admitted subarachnoid haemorrhage patients, 6999 survived more than three-months. During follow-up (mean 5·1 years), 874 (12·5%) died. The risks of death were 3·3% within one-year, 11·3% within five-years, and 21·5% within 10 years. The standardized mortality ratio was 3·4 (95% confidence interval: 3·1 to 3·7) for vascular death and 2·2 (95% confidence interval: 2·1 to 2·3) for all-cause death. The standardized incidence ratio for fatal or nonfatal vascular diseases was 2·7 (95% confidence interval: 2·6 to 2·8). Dutch hospital discharge and cause of death registries are a valid source of data for subarachnoid haemorrhage, and show that the increased mortality rate in subarachnoid haemorrhage survivors is explained by increased risks for vascular diseases and death. © 2012 The Authors.

    Massive haemorrhage remains a leading cause of maternal death worldwide. Interventional radiology can be used to prevent or treat life-threatening haemorrhage, but evidence for its efficacy is limited to case series predominantly from large tertiary centres. The current availability of interventional radiology for management of obstetric haemorrhage in the UK is unknown. A postal questionnaire on the use of interventional radiology was sent to the lead clinician for obstetric anaesthesia in 226 UK maternity units. The response rate was 72%; 74 respondents (46%) had considered and 51 (31%) used interventional radiology for control of obstetric haemorrhage. Its use was primarily confined to large tertiary obstetric units and limited by availability of equipment and staff. Interventional radiology to assist in the management of obstetric haemorrhage is not uniformly available in the UK and experience remains limited. Access to this resource is subject to striking local variability and influenced by the size and nature of the hospital supporting the delivery unit. 2010 Elsevier Ltd. All rights reserved.

    Background Peptic ulcer bleeding (PUB) is the main cause of non-variceal upper gastrointestinal bleeding (UGIB). Endoscopic treatment and acid suppression with proton-pump inhibitors (PPIs) are most important in the management of PUB and these treatments have reduced mortality. However, elderly patients sometimes have a poor prognostic outcome due to severe comorbidities. Methods A retrospective study was performed on 504 cases with acute non-variceal UGIB who were examined in our hospital, in order to reveal the risk factor of a poor outcome in elderly patients. Results Two hundred and thirty-four cases needed hemostasis; 11 cases had unsuccessful endoscopic treatments; 31 cases had re-bleeding after endoscopic hemostasis. Forty-three cases died within 30 days after the initial urgent endoscopy, but only seven cases died from bleeding. Elderly patients aged over 65 years had more severe comorbidities, and were prescribed non-steroidal anti-inflammatory drugs (NSAIDs), antiplatelet agents and/or anticoagulation agents, more frequently, compared with non-elderly patients. The significant risk factor of needing hemostatic therapy was the taking of two or more NSAIDs, antiplatelet agents and/or anticoagulation agents. The most important risk of a poor outcome in elderly patients was various kinds of severe comorbidities. And so, it is important to predict such an outcome in these cases. AIMS65 is a simple and relatively useful scoring system that predicts the risk of a poor outcome in UGIB. High-score patients via AIMS65 were associated with a high mortality rate because of death from comorbidities. Conclusions The elderly patients in whom were prescribed two or more NSAIDs, antiplatelet agents and/or anticoagulation agents, should have UGIB prevented using a PPI. The most significant risk of a poor outcome in elderly patients was severe comorbidities. We recommend that elderly patients with UGIB should be estimated as having a poor outcome as soon as possible via the

    Analyses of large databases have demonstrated that the association between heart rate (HR) and blood loss is weaker than what is taught by Advanced Trauma Life Support training. However, those studies had limited ability to generate a more descriptive paradigm, because they only examined a single HR value per patient. In a comparative, retrospective analysis, we studied the temporal characteristics of HR through time in adult trauma patients with haemorrhage, based on documented injuries and transfusion of ≥3 units of red blood cells (RBCs). We analysed archived vital-sign data of up to 60 min during either pre-hospital or emergency department care. We identified 133 trauma patients who met the inclusion criteria for major haemorrhage and 1640 control patients without haemorrhage. There were 55 haemorrhage patients with a normal median HR and 78 with tachycardia. Median ΔHR was -0.8 and +0.7 bpm per 10 min, respectively. Median time to documented hypotension was 8 and 5 min, respectively. RBCs were not significantly different; median volumes were 6 (IQR: 4-13) and 10 units (IQR: 5-16), respectively. Time-to-hypotension and mortality were not significantly different. Tachycardic patients were significantly younger (P < 0.05). Only 10 patients with normal HR developed transient/temporary tachycardia, and only 11 tachycardic patients developed a transient/temporary normal HR. The current analysis suggests that some trauma patients with haemorrhage are continuously tachycardic while others have a normal HR. For both cohorts, hypotension typically develops within 30 min, without any consistent temporal increases or trends in HR. Published by Elsevier Ltd.

    Automated grading has the potential to improve the efficiency of diabetic retinopathy screening services. While disease/no disease grading can be performed using only microaneurysm detection and image-quality assessment, automated recognition of other types of lesions may be advantageous. This study investigated whether inclusion of automated recognition of exudates and haemorrhages improves the detection of observable/referable diabetic retinopathy. Images from 1253 patients with observable/referable retinopathy and 6333 patients with non-referable retinopathy were obtained from three grading centres. All images were reference-graded, and automated disease/no disease assessments were made based on microaneurysm detection and combined microaneurysm, exudate and haemorrhage detection. Introduction of algorithms for exudates and haemorrhages resulted in a statistically significant increase in the sensitivity for detection of observable/referable retinopathy from 94.9% (95% CI 93.5 to 96.0) to 96.6% (95.4 to 97.4) without affecting manual grading workload. Automated detection of exudates and haemorrhages improved the detection of observable/referable retinopathy.

    Spontaneous intracerebral haemorrhage (ICH) imposes a significant health and economic burden on society. Despite this, ICH remains the only stroke subtype without a definitive treatment. Without a clearly identified and effective treatment for spontaneous ICH, clinical practice varies greatly from aggressive surgery to supportive care alone. This review will discuss the current modalities of treatments for ICH including preliminary experience and investigative efforts to advance the care of these patients. Open surgery (craniotomy), prothrombotic agents and other therapeutic interventions have failed to significantly improve the outcome of these stroke victims. Recently, the Surgical Trial in Intracerebral Haemorrhage (STICH) II assessed the surgical management of patients with superficial intraparenchymal haematomas with negative results. MISTIE II and other trials of minimally invasive surgery (MIS) have shown promise for improving patient outcomes and a phase III trial started in late 2013. ICH lacks a definitive primary treatment as well as a therapy targeting surrounding perihematomal oedema and associated secondary damage. An ongoing phase III trial using MIS techniques shows promise for providing treatment for these patients.

    Recurrent variceal hemorrhage is common following an initial bleed in patients with cirrhosis. The current standard of care for secondary prophylaxis is endoscopic band ligation (EBL). Combination of beta-blocker and nitrate therapy, guided by hepatic venous pressure gradient (HVPG) monitoring, is a novel alternative strategy. We sought to determine the cost-effectiveness of these competing strategies. Decision analysis with Markov modeling was used to calculate the cost-effectiveness of three competing strategies: (1) EBL; (2) beta-blocker and nitrate therapy without HVPG monitoring (HVPG-); and (3) beta-blocker and nitrate therapy with HVPG monitoring (HVPG+). Patients in the HVPG+ strategy who failed to achieve an HVPG decline from medical therapy were offered EBL. Cost estimates were from a third-party payer perspective. The main outcome measure was the cost per recurrent variceal hemorrhage prevented. Under base-case conditions, the HVPG+ strategy was the most effective yet most expensive approach, followed by EBL and HVPG-. Compared to the EBL strategy, the HVPG+ strategy cost an incremental 5,974 dollars per recurrent bleed prevented. In a population with 100% compliance with all therapies, the incremental cost of HVPG-versus EBL fell to 5,270 dollars per recurrent bleed prevented. The model results were sensitive to the cost of EBL, the cost of HVPG monitoring, and the probability of medical therapy producing an adequate HVPG decline. Compared to EBL for the secondary prophylaxis of variceal rebleeding, combination medical therapy guided by HVPG monitoring is more effective and only marginally more expensive.

    Bleeding from esophageal varices is an important cause of morbidity and mortality in patients with portal hypertension. The ideal surgical procedure should control bleeding with as little impairment of liver function as possible and with low rates of encephalopathy. Recently, significant progress in laparoscopic technology has enabled laparoscopic splenectomy and devascularization of the lower esophagus and upper stomach in a less invasive way. In this paper, we present preliminary results for 25 patients in whom laparoscopic splenectomy and azygoportal disconnection were performed. Laparoscopic splenectomy and devascularization of the lower esophagus and upper stomach were performed in 25 patients with cirrhosis, bleeding portal hypertension, and secondary hypersplenism between January 2000 and October 2006. Among them, 5 patients underwent a laparoscopic modified Sugiura procedure, the lower esophagus was transected, and then reanastomosed with a circular stapler. Laparoscopic splenectomy and azygoportal disconnection were completed in all patients, except in 1 conversion, without significant morbidity. The operation time ranged from 4.0 to 5.5 hours and the blood loss was 100-400 mL. The postoperative hospital stay was 6-15 days. During a postoperative follow-up period of 3 months to 5 years in 22 patients, neither esophagus variceal bleeding nor encephalopathy has recurred. Laparoscopic splenectomy and azygoportal disconnection are feasible, effective, and safe surgical procedures, and have all the benefits of minimally invasive surgery for patients with bleeding portal hypertension and hypersplenism. Laparoscopic splenectomy and azygoportal disconnection offer a new operative method for treatment of bleeding portal hypertension with hypersplenism.

    Summary To investigate factors effecting the safety and recanalization efficacy of local intraarterial (IA) recombinant tissue plasminogen activator (r-tPA) delivery in patients with acute ischemic stroke. Eleven patients with anterior circulation acute ischemic stroke were treated. The neurological status of the patients were graded with the Glasgow Coma Scale (GCS) and National Institute of Health Stroke Scale (NIHSS). All patients underwent a computed tomography (CT) examination at admission. In addition four patients had diffusion-weighted and one patient had a perfusion magnetic resonance (MR) examinations. Patients were treated within six hours from stroke onset. Immediate, six hours, and 24 hours follow-up CT examinations were performed in order to evaluate the haemorrhagic complications and the extent of the ischemic area. The Rankin Scale (RS) was used as an outcome measure. Two of the 11 patients had carotid “T” occlusion (CTO), nine had middle cerebral artery (MCA) main trunk occlusion. Four patients had symptomatic haemorrhage with a large haematoma rupturing into the ventricles and subarachnoid space. Of these, three patients died within 24 hours. The remaining seven patients had asymptomatic haematomas that were smaller compared to symptomatic ones, and showed regression in size and density on follow-up CTs. At third month five patients had a good outcome and three patients had a poor outcome. In acute ischemic stroke, local IA thrombolysis is a feasible treatment when you select the right patient. Haemorrhage rate does not seem to exceed that occuring in the natural history of the disease and in other treatment modalities. PMID:20591253

    Multi-detector-row computed tomography (MDCT) has been reported to be a potentially useful modality for detection of the bleeding origin in patients with acute upper massive gastrointestinal (GI) bleeding. The purpose of this study is to investigate the efficacy of MDCT as a routine method for detecting the origin of acute upper GI bleeding prior to urgent endoscopy. Five hundred seventy-seven patients with acute upper GI bleeding (514 nonvariceal patients, 63 variceal patients) who underwent urgent upper GI endoscopy were retrospectively analyzed. Patients were divided into three groups: enhanced MDCT, unenhanced MDCT, and no MDCT before endoscopy. The diagnostic accuracy of MDCT for detection of the bleeding origin was evaluated, and the average procedure times needed to endoscopically identify the bleeding origin were compared between groups. Diagnostic accuracy among endoscopists was 55.3% and 14.7% for the enhanced MDCT and unenhanced MDCT groups, respectively. Among nonvariceal patients, accuracy was 50.2% in the enhanced MDCT group, which was significantly better than that in the unenhanced MDCT group (16.5%). In variceal patients, accuracy was significantly better in the enhanced MDCT group (96.4%) than in the unenhanced MDCT group (0.0%). These accuracies were similar to those achieved by expert radiologists. The average procedure time to endoscopic detection of the bleeding origin in the enhanced MDCT group was significantly faster than that in the unenhanced MDCT and no-MDCT groups. Enhanced MDCT preceding urgent endoscopy may be an effective modality for the detection of bleeding origin in patients with acute upper GI bleeding. © 2013 Journal of Gastroenterology and Hepatology Foundation and Wiley Publishing Asia Pty Ltd.

    1. Long-lasting haemorrhagic hypotension (4·5 hr at 35 mmHg) leading to irreversible haemorrhagic shock, has been studied in normal dogs, in dogs treated with a bradykinin potentiating nonapeptide (BPP9a), which blocks the conversion of angiotensin I to angiotensin II, and in dogs with experimental chronic diabetes insipidus (DI dogs). BPP9a was given by I.V. injection before the start of bleeding (BPP pre-treated group), 45 min after blood pressure had reached 35 mmHg (BPP early treated group) or 2 hr after blood pressure had reached 35 mmHg (BPP late-treated group). After retransfusion of blood all dogs were allowed to recover and observed for a further period of 3 days. 2. Untreated control dogs developed haemorrhagic shock with tachycardia, low cardiac output, low total peripheral conductance and low stroke volume. All died within 24 hr of retransfusion, with pathological lesions typical of irreversible haemorrhagic shock. 3. BPP pre-treated dogs developed haemorrhagic shock with bradycardia (during early shock), high cardiac output, high peripheral vascular conductance and high stroke volume when compared with the untreated controls. All pre-treated animals survived the 3 day observation period. They were then killed and on post-mortem showed no signs of irreversible haemorrhagic shock. 4. BPP early-treated animals behaved like controls before BPP, but like pre-treated animals after the drug. Only one out of eight died within the 3 day observation period. 5. BPP late-treated dogs behaved like controls before BPP. They responded to the drug with a rise in cardiac output, peripheral vascular conductance and stroke volume, and with a fall in heart rate. These responses were, however, short-lived. Four out of these eight animals died within the 3 day observation period, with lesions of irreversible haemorrhagic shock. 6. DI dogs developed haemorrhagic shock with tachycardia (like controls), but with high cardiac output and peripheral vascular conductance (like

    Gastroesophageal variceal hemorrhage is a lethal complication of portal hypertension. Liver cirrhosis is often the principal cause of the portal hypertensive state. Malignant tumors coexist with portal hypertension in some cases. Non-small-cell lung cancer (NSCLC) is likely to become metastatic. Liver is a frequent site of cancer metastasis, but diffuse hepatic sinusoidal metastasis is uncommon as a metastatic form of NSCLC. This report describes a patient with gastroesophageal variceal hemorrhage owing to a metastatic liver tumor of NSCLC. The patient, a male smoker with stage IV NSCLC, was free of any hepatitis viral infection and had no alcohol addiction. Liver dysfunction and liver disease had never been pointed out in his medical history. His tumor harbored an L858R epidermal growth factor receptor mutation. Gefitinib was initiated but had to be ceased because of interstitial lung disease. Sequential steroid therapy was effective and bevacizumab-containing chemotherapy was commenced. Both chemotherapy regimens produced favorable effects against the metastatic liver tumor, eliciting atrophic change regardless of the chemotherapy-free interval. One day the patient was admitted to our hospital because of black stool and hypotension. Upper gastrointestinal endoscopy revealed a beaded appearance of the gastroesophageal varix with bloody gastric contents. The portal hypertension might have been caused by changes in portal vein hemodynamics induced by the conformational changes underlying the favorable response of the liver tumor to molecular targeted chemotherapy and notable regression.

    To determine the role of the number of bands placed per session upon patient-related and procedural-related outcomes. Patients were assigned to receive as many bands as could be possibly placed (group 1) or up to a maximum of six bands (group 2) per session. The primary outcome measured was the number of sessions to achieve obliteration. Other outcomes measured included: rebleeding, variceal recurrence, mortality (within 6 wk and within 1 yr), complications, banding and total procedure times, and number of bands misfired. A total of 86 patients were enrolled: 45 in group 1 and 41 in group 2. The two groups had similar age, Child-Pugh scores, grade of varices at entry. The overall proportion of patients achieving obliteration was 56% (53% and 59% for groups 1 and 2, respectively). Despite receiving significantly more mean bands per session, patients in group 1 required similar (mean +/- SEM) number of sessions to obliteration (2.9 +/- 0.3 vs 3.3 +/- 0.3) and total number of bands (20.0 +/- 2.4 vs 16.6 +/- 1.8) to achieve this goal compared with group 2. The overall proportion of patients with variceal rebleeding was 25%, the 1-yr variceal recurrence 31.3%, and the overall early- and 1-yr mortality were 18.6% and 33.7%, respectively. These proportions were similar in the two groups. Banding and total procedure times were significantly longer and associated with significantly more misfired bands per session in group 1. Compared with a maximum of six bands per session, the placement of >6 bands per session was not associated with better patient outcomes but with significantly more prolonged banding and total procedure times and significantly more misfired bands.

    A 73-year-old woman was admitted to hospital due to anaemia. She suffered a minor head trauma and deteriorated to deep unconsciousness. A CT revealed an acute subdural haematoma (ASDH). Initially, she was not found to be a candidate for neurosurgical intervention, but within 24 hours her level of consciousness improved dramatically, and a renewed CT showed resolution of the ASDH. She underwent acute craniotomy with good outcome. This illustrates the importance of re-evaluation of patients with intracranial haemorrhage.

    Sir William Osler meticulously described the clinical manifestations of infective endocarditis in 1885, concluding that: 'few diseases present greater difficulties in the way of diagnosis … which in many cases are practically insurmountable'. Even with modern investigation techniques, diagnosing infective endocarditis can be hugely challenging, yet is critically important in patients presenting with stroke (both cerebral infarction and intracranial haemorrhage), its commonest neurological complication. In ischaemic stroke, intravenous thrombolysis carries an unacceptably high risk of intracranial haemorrhage, while in intracerebral haemorrhage, mycotic aneurysms require urgent treatment to avoid rebleeding, and in all cases, prompt treatment with antibiotics and valve surgery may be life-saving. Here, we describe typical presentations of ischaemic stroke and intracerebral haemorrhage caused by infective endocarditis. We review the diagnostic challenges, the importance of rapid diagnosis, treatment options and controversies. Published by the BMJ Publishing Group Limited.

  3. Ebola haemorrhagic fever in Zaire, 1976

    PubMed Central

    1978-01-01

    Between 1 September and 24 October 1976, 318 cases of acute viral haemorrhagic fever occurred in northern Zaire. The outbreak was centred in the Bumba Zone of the Equateur Region and most of the cases were recorded within a radius of 70 km of Yambuku, although a few patients sought medical attention in Bumba, Abumombazi, and the capital city of Kinshasa, where individual secondary and tertiary cases occurred. There were 280 deaths, and only 38 serologically confirmed survivors. The index case in this outbreak had onset of symptoms on 1 September 1976, five days after receiving an injection of chloroquine for presumptive malaria at the outpatient clinic at Yambuku Mission Hospital (YMH). He had a clinical remission of his malaria symptoms. Within one week several other persons who had received injections at YMH also suffered from Ebola haemorrhagic fever, and almost all subsequent cases had either received injections at the hospital or had had close contact with another case. Most of these occurred during the first four weeks of the epidemic, after which time the hospital was closed, 11 of the 17 staff members having died of the disease. All ages and both sexes were affected, but women 15-29 years of age had the highest incidence of disease, a phenomenon strongly related to attendance at prenatal and outpatient clinics at the hospital where they received injections. The overall secondary attack rate was about 5%, although it ranged to 20% among close relatives such as spouses, parent or child, and brother or sister. Active surveillance disclosed that cases occurred in 55 of some 550 villages which were examined house-by-house. The disease was hitherto unknown to the people of the affected region. Intensive search for cases in the area of north-eastern Zaire between the Bumba Zone and the Sudan frontier near Nzara and Maridi failed to detect definite evidence of a link between an epidemic of the disease in that country and the outbreak near Bumba. Nevertheless it was

    Pre-endoscopic triage of patients who require an early upper endoscopy can improve management of patients with non-variceal upper gastrointestinal bleeding. To validate a new simplified clinical score (T-score) to assess the need of an early upper endoscopy in non variceal bleeding patients. Secondary outcomes were re-bleeding rate, 30-day bleeding-related mortality. In this prospective, multicentre study patients with bleeding who underwent upper endoscopy were enrolled. The accuracy for high risk endoscopic stigmata of the T-score was compared with that of the Glasgow Blatchford risk score. Overall, 602 patients underwent early upper endoscopy, and 472 presented with non-variceal bleeding. High risk endoscopic stigmata were detected in 145 (30.7%) cases. T-score sensitivity and specificity for high risk endoscopic stigmata and bleeding-related mortality was 96% and 30%, and 80% and 71%, respectively. No statistically difference in predicting high risk endoscopic stigmata between T-score and Glasgow Blatchford risk score was observed (ROC curve: 0.72 vs. 0.69, p=0.11). The two scores were also similar in predicting re-bleeding (ROC curve: 0.64 vs. 0.63, p=0.4) and 30-day bleeding-related mortality (ROC curve: 0.78 vs. 0.76, p=0.3). The T-score appeared to predict high risk endoscopic stigmata, re-bleeding and mortality with similar accuracy to Glasgow Blatchford risk score. Such a score may be helpful for the prediction of high-risk patients who need a very early therapeutic endoscopy. Copyright © 2014 Editrice Gastroenterologica Italiana S.r.l.

    2016-01-01

    Upper gastrointestinal (UGI) bleeding is generally defined as bleeding proximal to the ligament of Treitz, which leads to hematemesis. There are several causes of UGI bleeding necessitating a detailed history to rule out comorbid conditions, medications, and possible exposures. In addition, the severity, timing, duration, and volume of the bleeding are important details to note for management purposes. Despite the source of the bleeding, acid suppression with a proton-pump inhibitor has been shown to be effective in minimizing rebleeding. Endoscopy remains the interventional modality of choice for both nonvariceal and variceal bleeds because it can be diagnostic and therapeutic. Copyright © 2016 Elsevier Inc. All rights reserved.

    Background & objectives: Differential diagnosis of Crimean-Congo haemorrhagic fever (CCHF) from other acute febrile illnesses with haemorrhagic manifestation is challenging in India. Nosocomial infection is a significant mode of transmission due to exposure of healthcare workers to blood and body fluids of infected patients. Being a risk group 4 virus, laboratory confirmation of infection is not widely available. In such a situation, early identification of potential CCHF patients would be useful in limiting the spread of the disease. The objective of this study was to retrospectively analyse clinical and laboratory findings of CCHF patients that might be useful in early detection of a CCHF case in limited resource settings. Methods: Retrospective analysis of clinical and laboratory data of patients suspected to have CCHF referred for diagnosis from Gujarat and Rajasthan States of India (2014-2015) was done. Samples were tested using CCHF-specific real time reverse transcription (RT)-PCR and IgM ELISA. Results: Among the 69 patients referred, 21 were laboratory confirmed CCHF cases of whom nine had a history of occupational exposure. No clustering of cases was noted. Platelet count cut-off for detection of positive cases by receiver operating characteristic curve was 21.5×10[9]/l with sensitivity 82.4 per cent and specificity 82.1 per cent. Melaena was a significant clinical presentation in confirmed positive CCHF patients. Interpretation & conclusions: The study findings suggest that in endemic areas thrombocytopenia and melaena may be early indicators of CCHF. Further studies are needed to confirm these findings.

    A total of 142 women with severe acute renal failure (ARF) resulting from obstetric causes was treated by dialysis at a single centre from 1956 to 1987. One-year survival was 78.6%, which compares favourably with other causes of ARF. Abortion, haemorrhage and preclampsia comprised 95% of cases, with survival being best (82.9%) with abortion. Survival was adversely affected by increasing age. Acute cortical necrosis (12.7% of patients) carried 100% mortality after 6 years. Follow-up of survivors showed normal renal function up to 31 years following ARF; 25-year patient survival was 71.6%. Improvements in obstetric care and the disappearance of illegal abortions have resulted in a dramatic decline in the incidence of obstetric ARF.

    Brain arachnoid cysts (AC) are congenital or acquired malformations. Their prevalence in children ranges between 0.2 and 2.3% of the studied populations. Few reported studies exist where AC appears after a subdural haemorrhage. We present one case of a symptomatic suprasellar AC after post-traumatic subdural haemorrhage in an infant. After endoscopic ventriculocystostomy, the child quickly improved and the cyst reduced in size. The child was monitored for 22 months and his neurocognitive development remained normal. Our case led us to the hypothesis that the inflammatory process due to subdural haemorrhage may locally result in arachnoiditis, and thus to the creation of a neomembrane, and eventually to cyst formation. This is also the case with the development of post-traumatic spinal AC. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

    Behçet's disease (BD) is a multisystemic disorder that involves vessels of all sizes. Superior vena cava (SVC) thrombosis is a rare complication that can lead to the development of various collateral pathways. A 31-year-old man presented with SVC syndrome. He had a history of recurrent genital aphthosis. Computed tomography revealed extensive thrombosis of the right internal jugular, axillary, and subclavian veins with collateral circulation. The patient was diagnosed with BD, and he was started on anticoagulation and immunosuppressive therapy. One week later, he presented with haematemesis. Upper gastrointestinal endoscopy disclosed varices in the upper third of the oesophagus with stigmata of recent bleeding. Portal hypertension was ruled out. Anticoagulation therapy was discontinued. He was discharged on immunosuppressive therapy. Bleeding from downhill oesophageal varices should be suspected in any patient presenting with upper gastrointestinal bleeding and a history of SVC syndrome due to BD.

    The relationship of this country with dengue has been long and intense. The ?rst recorded epidemic of clinically dengue-like illness occurred at Madras in 1780 and the dengue virus was isolated for the ?rst time almost simultaneously in Japan and Calcutta in 1943-1944. After the ?rst virologically proved epidemic of dengue fever along the East Coast of India in 1963-1964, it spread to allover the country.The ?rst full-blown epidemic of the severe form of the illness,the dengue haemorrhagic fever/dengue shock syndrome occurred in North India in 1996. Aedes aegypti is the vector for transmission of the disease. Vaccines or antiviral drugs are not available for dengue viruses; the only effective way to prevent epidemic degure fever/dengue haemorrhagic fever (DF/DHF) is to control the mosquito vector, Aedes aegypti and prevent its bite. This country has few virus laboratories and some of them have done excellent work in the area of molecular epidemiology,immunopathology and vaccine development. Selected work done in this country on the problems of dengue is presented here.

    Recently, we demonstrated that Kv7 voltage-activated potassium channel inhibitors reduce fluid resuscitation requirements in short-term rat models of haemorrhagic shock. The aim of the present study was to further delineate the therapeutic potential and side effect profile of the Kv7 channel blocker linopirdine in various rat models of severe haemorrhagic shock over clinically relevant time periods. Intravenous administration of linopirdine, either before (1 or 3 mg/kg) or after (3 mg/kg) a 40% blood volume haemorrhage, did not affect blood pressure and survival in lethal haemorrhage models without fluid resuscitation. A single bolus of linopirdine (3 mg/kg) at the beginning of fluid resuscitation after haemorrhagic shock transiently reduced early fluid requirements in spontaneously breathing animals that were resuscitated for 3.5 hours. When mechanically ventilated rats were resuscitated after haemorrhagic shock with normal saline (NS) or with linopirdine-supplemented (10, 25 or 50 μg/mL) NS for 4.5 hours, linopirdine significantly and dose-dependently reduced fluid requirements by 14%, 45% and 55%, respectively. Lung and colon wet/dry weight ratios were reduced with linopirdine (25/50 μg/mL). There was no evidence for toxicity or adverse effects based on measurements of routine laboratory parameters and inflammation markers in plasma and tissue homogenates. Our findings support the concept that linopirdine-supplementation of resuscitation fluids is a safe and effective approach to reduce fluid requirements and tissue oedema formation during resuscitation from haemorrhagic shock. © 2018 John Wiley & Sons Australia, Ltd.

    Antibiotics frequently are overused and are associated with serious adverse events in patients with cirrhosis. However, these drugs are recommended for all patients presenting with acute variceal hemorrhage (AVH). We investigated whether patients should be stratified for antibiotic prophylaxis based on Child-Pugh scores, to estimate risks of bacterial infection, rebleeding, and mortality, and whether antibiotics have equal effects on patients of all Child-Pugh classes. We performed a sensitivity analysis using model for end-stage liver disease (MELD) scores. In a retrospective study, we analyzed data from 381 adult patients with cirrhosis and AVH (70% men; mean age, 56 y), admitted from 2000 through 2009 to 2 tertiary care hospitals in Edmonton, Alberta, Canada. We excluded patients with bacterial infection on the day of AVH. The association between antibiotic prophylaxis and outcomes was adjusted by liver disease severity and by a propensity score. The patients included in the study had mean MELD scores of 16, and 54% received antibiotic prophylaxis. Overall, antibiotic therapy was associated with lower risks of infection (adjusted odds ratio, 0.37; 95% confidence interval, 0.91-0.74) and mortality (adjusted odds ratio, 0.63; 95% confidence interval, 0.31-1.29). Among patients categorized as Child-Pugh class A given antibiotics, only 2% developed infections and the mortality rate was 0.4%. Among patients categorized as Child-Pugh class B given antibiotics, 6% developed infections, compared with 14% of patients who did not receive antibiotics; antibiotics did not affect mortality. Administration of antibiotics to patients categorized as Child-Pugh class C reduced infections and mortality by approximately 50%, compared with patients who did not receive antibiotics. MELD scores were not as useful as Child-Pugh class in identifying patients at risk for infection. Based on a retrospective analysis of patients with cirrhosis and AVH, those categorized as Child

    Patients undergoing cardiac surgery with extracorporeal circulation (ECC) frequently present haemorrhages as a complication associated with high morbidity and mortality. One of the factors that influences this risk is the volume of blood infused during surgery. The objective of this study was to determine the optimal volume of autologous blood that can be processed during cardiac surgery with ECC. We also determined the number of salvaged red blood cells to be reinfused into the patient in order to minimize the risk of haemorrhage in the postoperative period. This was an observational retrospective cross-sectional study performed in 162 ECC cardiac surgery patients. Data regarding the sociodemographic profiles of the patients, their pathologies and surgical treatments, and the blood volume recovered, processed, and reinfused after cell salvage were collected. We also evaluated the occurrence of postoperative haemorrhage. The volume of blood infused after cell salvage had a statistically significant effect (p < 0.01) on the risk of post-operative haemorrhage; the receiver operating characteristic sensitivity was 0.813 and the optimal blood volume cut-off was 1800 ml. The best clinical outcome (16.7% of patients presenting haemorrhages) was in patients that had received less than 1800 ml of recovered and processed autologous blood, which represented a volume of up to 580 ml reinfused red blood cells. The optimum thresholds for autologous processed blood and red blood cells reinfused into the patient were 1800 and 580 ml, respectively. Increasing these thresholds augmented the risk of haemorrhage as an immediate postoperative period complication.

    Dengue is an endemic arboviral infection prevalent especially in tropical countries including Southern and Southeast Asia. Central Nervous System (CNS) involvement in dengue infection is uncommon. Haemorrhagic encephalitis is a rare presentation in dengue. This is a case of a 58-year-old male who presented with fever, petechial rash and altered sensorium. Dengue serology IgM was reactive and MRI brain was suggestive of haemorrhagic encephalitis. Patient was managed in Intensive Care Unit (ICU) but eventually succumbed to his illness. We report this fatal outcome of a common viral infection with unusual neurological presentation to propose an association between dengue and neurotropism and the need to look at dengue infection beyond its classical features.

    Marburg virus causes a highly infectious and lethal haemorrhagic fever in primates and may be exploited as a potential biothreat pathogen. To combat the infection and threat of Marburg haemorrhagic fever, there is a need to develop and license appropriate medical countermeasures. To determine whether the common marmoset (Callithrix jacchus) would be an appropriate model to assess therapies against Marburg haemorrhagic fever, initial susceptibility, lethality and pathogenesis studies were performed. Low doses of virus, between 4 and 28 TCID50, were sufficient to cause a lethal, reproducible infection. Animals became febrile between days 5 and 6, maintaining a high fever before succumbing to disease between 8 and 11 days postchallenge. Typical signs of Marburg virus infection were observed including haemorrhaging and a transient rash. In pathogenesis studies, virus was isolated from the animals’ lungs from day 3 postchallenge and from the liver, spleen and blood from day 5 postchallenge. Early signs of histopathology were apparent in the kidney and liver from day 3. The most striking features were observed in animals exhibiting severe clinical signs, which included high viral titres in all organs, with the highest levels in the blood, increased levels in liver function enzymes and blood clotting times, decreased levels in platelets, multifocal moderate-to-severe hepatitis and perivascular oedema.

    Healthy male rats were acclimatized by being placed in a decompression chamber at a simulated altitude of 18 000 feet (5486 m) for three hours daily for 84 days. The altitude acclimatized rats paired with unacclimatized rats were rapidly decompressed together. The range of decompression was performed from on atmospheric pressure to an ambient pressure of 30 mmHg in 0-2 seconds. It was found that in control rats, 14 of 20 lung (70%) exhibited pulmonary haemorrhage following rapid decompression. In altitude acclimatized rats, however, only 6 of 20 (30%) revealed decompression-induced haemorrhage. The difference was statistically significant. The present findings indicate that long-term intermittent exposures to hypoxia might increase the resistance of pulmonary tissue to rapid decompression, resulting in a decrease in frequency and severity of pulmonary haemorrhage. The possible mechanism of such a phenomenon is discussed. PMID:1257942

    Aspartate aminotransferase-to-platelet ratio (APRI), aspartate aminotransferase-to-alanine aminotransferase ratio (AAR), FIB-4, FI, King, Lok, Forns, and FibroIndex scores may be simple and convenient noninvasive diagnostic tests, because they are based on the regular laboratory tests and demographic data. This study aimed to systematically evaluate their diagnostic accuracy for the prediction of varices in liver cirrhosis.All relevant papers were searched via PubMed, EMBASE, CNKI, and Wanfang databases. The area under the summary receiver operating characteristic curve (AUSROC), sensitivity, specificity, positive and negative likelihood ratio (PLR and NLR), and diagnostic odds ratio (DOR) were calculated.Overall, 12, 4, 5, 0, 0, 4, 3, and 1 paper was identified to explore the diagnostic accuracy of APRI, AAR, FIB-4, FI, King, Lok, Forns, and FibroIndex scores, respectively. The AUSROCs of APRI, AAR, FIB-4, Lok, and Forns scores for the prediction of varices were 0.6774, 0.7275, 0.7755, 0.7885, and 0.7517, respectively; and those for the prediction of large varices were 0.7278, 0.7448, 0.7095, 0.7264, and 0.6530, respectively. The diagnostic threshold effects of FIB-4 and Forns scores for the prediction of varices were statistically significant. The sensitivities/specificities/PLRs/NLRs/DORs of APRI, AAR, and Lok scores for the prediction of varices were 0.60/0.67/1.77/0.58/3.13, 0.64/0.63/1.97/0.54/4.18, and 0.74/0.68/2.34/0.40/5.76, respectively. The sensitivities/specificities/PLRs/NLRs/DORs of APRI, AAR, FIB-4, Lok, and Forns scores for the prediction of large varices were 0.65/0.66/2.15/0.47/4.97, 0.68/0.58/2.07/0.54/3.93, 0.62/0.64/2.02/0.56/3.57, 0.78/0.63/2.09/0.37/5.55, and 0.65/0.61/1.62/0.59/2.75, respectively.APRI, AAR, FIB-4, Lok, and Forns scores had low to moderate diagnostic accuracy in predicting the presence of varices in liver cirrhosis.

    The aim of this study was to identify the ability of Glasgow-Blatchford score (GBS) and pre-endoscopic Rockall score (pre-E RS) to predict the occurrence of hypotension in patients with non-variceal upper gastrointestinal bleeding who are initially normotensive at emergency department. Retrospective observational study was conducted at Asan Medical Center emergency department (ED) in patients who presented with non-variceal upper gastrointestinal bleeding from January 1, 2011 to December 31, 2013. Study population was divided according to the development of hypotension, and demographics, comorbidities, and laboratory findings were compared. GBS and pre-E RS were estimated to predict the occurrence of hypotension. A total of 747 patients with non-variceal upper gastrointestinal bleeding were included during the study period, and 120 (16.1%) patients developed hypotension within 24 hours after ED admission. The median values GBS and pre-E RS were statistically different according to the occurrence of hypotension (8.0 vs. 10.0, 2.0 vs. 3.0, respectively; p<0.001). In the receiver operating characteristic curve analysis of hypotension development, the area under the curve of GBS and pre-E RS were 66% and 64%, respectively. The sensitivity and the specificity of GBS using optimal cut-off value were 81% and 46%, respectively, while those based on the pre-E RS were 74% and 46%, respectively. GBS and pre-E RS were both not sufficient for predicting the occurrence of hypotension in non-variceal upper gastrointestinal bleeding. Development of other scoring systems are needed.

    Cerebral venous thrombosis (CVT) is an uncommon but serious type of stroke. Thrombosis may involve the cortical or deep veins or the venous sinuses. The presenting clinical features are non-specific. We report a 48-year-old man with CVT who presented with fever, bitemporal throbbing headache, and generalised convulsion. Computed tomography (CT) of the brain revealed acute haemorrhages over right anterior frontal and posterior temporal regions with surrounding oedema and right anterior temporal subcortical oedema. The initial diagnosis was herpes simplex encephalitis. Absence of venous flow over the right transverse and sigmoid sinuses during the venous phase of digital subtraction angiography (DSA) revealed CVT. He was anti-coagulated for 6 months. An underlying cause of CVT was not detected. A high index of suspicion is required when risk factors of CVT are present. CT brain may be normal or showing non-specific findings. Magnetic resonance imaging plus venography, CT venography, or DSA is diagnostic.

    To ascertain the number of cases of spontaneous (aneurysmal) subarachnoid haemorrhage presenting to Tan Tock Seng Hospital, Singapore, over a one year period, the demographics of the patients involved, their treatment and their eventual outcome. A retrospective study from June 1995 to June 1996. There were 62 patients admitted over this period with an average of 5 patients per month. Their ages ranged from 9 to 85 years with a mean of 54 years. All 62 patients underwent 4-vessel cerebral angiograms. Forty-three patients (69%) underwent clipping of their aneurysms. Twelve patients (19%) had negative angiograms. Four patients (6%) underwent coiling of their aneurysms via interventional neuroradiology techniques. Patients with subarachnoid haemorrhage of Grades 1 to 3 on the WFNS (World Federation of Neurological Surgeons) grading had a favourable outcome (Glasgow Outcome Score of 4 and 5) in 85% of the cases. The overall mortality rate for the operated group (all grades) was 11%. However for the group with good WFNS grading, namely the Grade 1 to 2 groups, there were no deaths. Twenty-four percent of patients developed clinically symptomatic vasospasm. Eighteen percent of patients required ventriculo-peritoneal shunting for hydrocephalus secondary to the subarachnoid haemorrhage. The overall management mortality (operated and non-operated cases) was 14% for proven aneurysmal and angiographically-negative spontaneous subarachnoid haemorrhage. These results are comparable to that of other reputable centers reported in the literature.

  5. Thrombolysis in Acute Ischaemic Stroke: An Update

    2011-01-01

    Stroke is a major cause of mortality and morbidity, and thrombolysis has served as a catalyst for major changes in the management of acute ischaemic stroke. Intravenous alteplase (recombinant tissue plasminogen activator) is the only approved thrombolytic agent at present indicated for acute ischaemic stoke. While the licensed time window extends to 3h from symptom onset, recent data suggest that the trial window can be extended up to 4.5 h with overall benefit. Nonetheless, 'time is brain' and every effort must be made to reduce the time delay to thrombolysis. Intracranial haemorrhage is the major complication associated with thrombolysis, and key factors increasing risk of haemorrhage include increasing age, high blood pressure, diabetes and stroke severity. Currently, there is no direct evidence to support thrombolysis in patients >80 years of age, with a few case series indicating no overt harm. Identification of viable penumbra based on computed tomography/magnetic resonance imaging may allow future extension of the time window. Adjuvant transcranial Doppler ultrasound has the potential to improve reperfusion rates. While intra-arterial thrombolysis has been in vogue for a few decades, there is no clear advantage over intravenous thrombolysis. The evidence base for thrombolysis in specific situations (e.g. dissection, pregnancy) is inadequate, and individualized decisions are needed, with a clear indication to the patient/carer about the lack of direct evidence, and the risk-benefit balance. Patient-friendly information leaflets may facilitate the process of consent for thrombolysis. This article summarizes the recent advances in thrombolysis for acute ischaemic stroke. Key questions faced by clinicians during the decision-making process are answered based on the evidence available. PMID:23251746

    Understanding the response of the brain to haemorrhagic damage is important in haemorrhagic stroke and increasingly in the understanding the cerebral degeneration and dementia that follow head trauma and head-impact sports. In addition, there is growing evidence that haemorrhage from small cerebral vessels is important in the pathogenesis of age-related dementia (Alzheimer’s disease). In a penetration injury model of rat cerebral cortex, we have examined the neuropathology induced by a needlestick injury, with emphasis on features prominent in the ageing and dementing human brain, particularly plaque-like depositions and the expression of related proteins. Needlestick lesions were made in neo- and hippocampal cortex in Sprague Dawley rats aged 3–5 months. Brains were examined after 1–30 d survival, for haemorrhage, for the expression of hyperphosphorylated tau, Aβ, amyloid precursor protein (APP), for gliosis and for neuronal death. Temporal cortex from humans diagnosed with Alzheimer’s disease was examined with the same techniques. Needlestick injury induced long-lasting changes–haem deposition, cell death, plaque-like deposits and glial invasion–along the needle track. Around the track, the lesion induced more transient changes, particularly upregulation of Aβ, APP and hyperphosporylated tau in neurons and astrocytes. Reactions were similar in hippocampus and neocortex, except that neuronal death was more widespread in the hippocampus. In summary, experimental haemorrhagic injury to rat cerebral cortex induced both permanent and transient changes. The more permanent changes reproduced features of human senile plaques, including the formation of extracellular deposits in which haem and Aβ-related proteins co-localised, neuronal loss and gliosis. The transient changes, observed in tissue around the direct lesion, included the upregulation of Aβ, APP and hyperphosphorylated tau, not associated with cell death. The findings support the possibility

    Haemorrhagic shock leads to decreased proinflammatory cytokine response which is associated with an increased susceptibility to bacterial infections. In the present study, the effect of GM-CSF on lipopolysaccharide (LPS)-induced TNF-alpha release and MAPkinase activation was analysed on the background of a possible immunostimulating activity of this substance. Male BALB/c mice were bled to a mean arterial blood pressure of 50 mmHg for 45 min followed by resuscitation. Peritoneal macrophages were isolated 20 h after haemorrhage and incubated with 10 ng/ml GM-CSF for 6h before LPS stimulation. TNF-alpha synthesis was studied in the culture supernatants using ELISA. Phosphorylation of ERK, p38MAPK and IkappaBalpha was detected by Western blotting. LPS-induced TNF-alpha production of peritoneal macrophages was significantly decreased 20 h after haemorrhage in comparison to the corresponding cells of sham-operated mice. In parallel the phosphorylation of IkappaBalpha was less in LPS-stimulated peritoneal macrophages from haemorrhagic mice. LPS-induced phosphorylation of ERK1/2 was also decreased in peritoneal macrophages isolated after haemorrhagic shock. In contrast, p38MAPK was phosphorylated more intensely after LPS-stimulation in macrophages collected from shocked mice. GM-CSF incubation elevated LPS-induced TNF-alpha response of macrophages from both sham-operated and shocked mice which was accompanied by an elevated IkappaB and ERK phosphorylation. In general, GM-CSF treatment in vitro enhanced peritoneal macrophages LPS-response both in terms of TNF-alpha synthesis and IkappaB and MAPK signalling, but the levels always stayed lower than those of GM-CSF-treated cells from sham-operated animals. In conclusion, GM-CSF preincubation could partly reactivate the depressed functions of peritoneal macrophages and may therefore exert immunostimulating properties after shock or trauma.

    A 75-year-old lady presented with sudden severe headache and vomiting. Examination was normal, and CT and lumbar puncture not convincing for subarachnoid haemorrhage. Shortly thereafter, she developed painless diplopia. Examination confirmed right third cranial nerve palsy plus homonymous left inferior quadrantanopia. Urgent cerebral MRI with angiography was requested to assess for a possible posterior communicating artery aneurysm, but revealed an unsuspected pituitary mass. Pituitary adenoma with pituitary apoplexy was diagnosed. Pituitary apopolexy is a syndrome comprising sudden headache, meningism, visual and/or oculomotor deficits, with an intrasellar mass. It is commonly due to haemorrhage or infarction within a pituitary adenoma. Treatment includes prompt steroid administration, and potentially surgical decompression. While subarachnoid haemorrhage is an important, well-recognised cause of sudden severe headache, other aetiologies, including pituitary apoplexy, should be considered and sought.

    To evaluate technical safety, clinical safety, and effectiveness of vascular plug-assisted retrograde transvenous obliteration (RTO) for treatment of gastric varices (GV) and hepatic encephalopathy (HE). This retrospective study was approved by the institutional review board; written informed consent was waived. From April 2009 to December 2011, 20 patients (13, GV; seven, HE) who had undergone vascular plug-assisted RTO were retrospectively evaluated. After retrograde transvenous placement of a vascular plug in the left adrenal vein or gastrorenal shunt, subsequent gelatin-sponge embolization of both gastrorenal shunt and GV was performed. Follow-up computed tomography (CT) and upper gastrointestinal tract endoscopy were performed; clinical and laboratory data were collected to evaluate primary (technical success, complications, clinical success) and secondary (change of liver function by using the Child-Pugh score, worsening of esophageal varices) end points. Laboratory data before and after vascular plug-assisted RTO were compared (paired-sample t test). Placement of the vascular plug and subsequent gelatin-sponge embolization were technically successful in all 20 patients, with no procedure-related complications. Follow-up CT within 1 week after vascular plug-assisted RTO showed complete thrombosis of GV and gastrorenal shunts in all patients. Clinical symptoms of HE completely resolved in all seven patients with HE; mean serum NH3 level of 127.4 μmol/L ± 58 (standard deviation) before vascular plug-assisted RTO decreased significantly to 28.1 μmol/L ± 9.8 within 1 week after vascular plug-assisted RTO (P = .002). Eighteen patients who underwent follow-up longer than 2 months showed complete obliteration of GV and gastrorenal shunts at CT and endoscopy. There were no cases of variceal bleeding or HE during mean follow-up of 422 days. Improvement in Child-Pugh score was observed in 12 of 18 (67%) patients 1 month after vascular plug-assisted RTO.

    A 38-year-old woman experienced a massive postpartum haemorrhage 30 minutes after emergency caesarean delivery. The patient became severely haemodynamically compromised with an unrecordable blood pressure. Rapid fluid resuscitation was limited by the capacity of the intravenous cannula in place at the time and inability to establish additional vascular access using conventional routes in a timely manner. An intraosseous needle was inserted in the proximal humerus at the first attempt and administration of resuscitation fluid by this route subsequently enabled successful placement of further intravenous lines. Blood and blood products were deployed in conjunction with intra-operative cell salvage and transoesophageal Doppler cardiac output monitoring was used to assess adequacy of volume replacement. Haemorrhage control was finally achieved with the use of recombinant factor VIIa and hysterectomy. © 2011 The Authors.

    Controversy exists over the prognostic significance of the affected hemisphere in stroke. We aimed to determine the relationship between laterality of acute intracerebral haemorrhage (ICH) and poor clinical outcomes. A subsidiary analysis of the INTERACT Pilot and INTERACT2 studies--randomised controlled trials of patients with spontaneous acute ICH with elevated systolic blood pressure (BP), randomly assigned to intensive (target systolic BP <140 mm Hg) or guideline-based (<180 mm Hg) BP management. Outcomes were the combined and separate end points of death and major disability (modified Rankin scale (mRS) scores of 3-6, 6 and 3-5, respectively) at 90 days. A total of 2708 patients had supratentorial/hemispheric ICH and information on mRS at 90 days. Patients with right hemispheric ICH (1327, 49%) had a higher risk of death at 90 days compared to those with left hemispheric ICH after adjustment for potential confounding variables (OR, 1.77 (95% CI 1.33 to 2.37)). There were no differences between patients with right and left hemispheric ICH regarding the combined end point of death or major disability or major disability in the multivariable-adjusted models (1.07 (0.89 to 1.29) and 0.85 (0.72 to 1.01), respectively). Right hemispheric lesion was associated with increased risk of death in patients with acute ICH. The laterality of the ICH does not appear to affect the level of disability in survivors.

  16. Cirrhotic portal hypertension: current and future medical therapy for primary and secondary prevention of variceal bleeding.

    PubMed

    Laleman, W; Nevens, F

    2006-08-01

    Portal hypertension (PHT) is the most common complication of chronic liver disease and develops in the vast majority of patients with cirrhosis. It is characterized by an increase of the portal vein pressure, and leads to the development of gastroesophageal varices, ascites, renal dysfunction and hepatic encephalopathy. Over the years, it has become clear that a decrease in portal pressure is not only protective against the risk of variceal (re)bleeding but is also associated with a lower long-term risk of developing other complications and with an improved long-term survival. At present, non-selective b-blockers remain the medical treatment of choice for both primary and secondary prophylaxis. However, recent advances in the knowledge of the pathophysiology of cirrhotic PHT have directed future therapy towards the increased intrahepatic vascular resistance, which in part is determined by an increased hepatic vascular tone. This increased vasculogenic component provides the motivation to the use of therapies aimed at increasing intrahepatic vasorelaxing capacity on the one hand and at antagonizing excessive intrahepatic vasoconstrictor force on the other hand. This review covers current and future developments in the treatment of PHT with regard to primary and secondary prophylaxis.

    Bleeding diathesis and a hyper-fibrinolytic state often accompany a diagnosis of Acute Promyelocytic Leukaemia (APML). This complication can have grave effects if not successfully treated, with a 10-20% incidence of haemorrhagic death. We hypothesized that alpha-2-antiplasmin levels would correlate with the risk for bleeding, and that administration of epsilon-aminocaproic acid (EACA) would attenuate that risk. To assess this, we conducted a retrospective chart review analyzing 30 APML patients, 17 of whom were treated with EACA. Thirty patients were treated, 21 with primary induction therapy. Patients with low alpha-2-antiplasmin levels were treated with a coagulopathy protocol consisting of low-dose heparin, EACA and blood product support. Seventeen patients (57%) developed haemorrhagic complications during their treatment. The presence and grade of haemorrhage appeared to be associated with the alpha-2-antiplasmin level. There were no grade IV haemorrhages or episodes of haemorrhagic death. One episode of central venous catheter associated thromboembolism and three deaths from infection during chemotherapy were observed. alpha-2-Antiplasmin levels are a reliable surrogate for fibrinolysis and haemorrhagic risk in patients with APML. Treatment with EACA is a rational way to pharmacologically inhibit fibrinolysis, is associated with a low incidence of severe haemorrhagic events, and appears to be safe with a low risk of thrombosis. Randomized clinical trials further assessing the efficacy and potential toxicity of EACA in inhibiting fibrinolysis in patients with APML are needed. Copyright (c) 2008 John Wiley & Sons, Ltd.

    Identification of lobar spontaneous intracerebral haemorrhage associated with cerebral amyloid angiopathy (CAA) is important because it is associated with a higher risk of recurrent intracerebral haemorrhage than arteriolosclerosis-associated intracerebral haemorrhage. We aimed to develop a prediction model for the identification of CAA-associated lobar intracerebral haemorrhage using CT features and genotype. We identified adults with first-ever intracerebral haemorrhage diagnosed by CT, who died and underwent research autopsy as part of the Lothian IntraCerebral Haemorrhage, Pathology, Imaging and Neurological Outcome (LINCHPIN) study, a prospective, population-based, inception cohort. We determined APOE genotype and radiologists rated CT imaging appearances. Radiologists were not aware of clinical, genetic, and histopathological features. A neuropathologist rated brain tissue for small vessel diseases, including CAA, and was masked to clinical, radiographic, and genetic features. We used CT and APOE genotype data in a logistic regression model, which we internally validated using bootstrapping, to predict the risk of CAA-associated lobar intracerebral haemorrhage, derive diagnostic criteria, and estimate diagnostic accuracy. Among 110 adults (median age 83 years [IQR 76-87], 49 [45%] men) included in the LINCHPIN study between June 1, 2010 and Feb 10, 2016, intracerebral haemorrhage was lobar in 62 (56%) participants, deep in 41 (37%), and infratentorial in seven (6%). Of the 62 participants with lobar intracerebral haemorrhage, 36 (58%) were associated with moderate or severe CAA compared with 26 (42%) that were associated with absent or mild CAA, and were independently associated with subarachnoid haemorrhage (32 [89%] of 36 vs 11 [42%] of 26; p=0·014), intracerebral haemorrhage with finger-like projections (14 [39%] of 36 vs 0; p=0·043), and APOE ɛ4 possession (18 [50%] of 36 vs 2 [8%] of 26; p=0·0020).

    Gastric varices (GVs) are a common finding in Egyptian patients with portal hypertension due to cirrhosis or schistosomal hepatic fibrosis. These patients present with an acute attack or history of hematemesis. Endoscopic histoacryl injection is the standard treatment in Egypt; however, because of technical difficulties it is possible to inject only a little amount of this material, as it may endanger the channels of the flexible endoscope. We thought of a new surgical laparoendoscopic technique to obviate the need for repeated endoscopies and complete obliteration of GVs. This study was conducted on 20 patients with portal hypertension and GVs. After the patient was placed under general anesthesia, a small gastrostomy was done in the anterior gastric wall through which a 10-mm trocar was inserted for the laparoscopic camera. Injection of GVs was done via a spinal needle or a central venous line needle inserted directly. Injection of an adequate amount of histoacryl was done under direct vision. This study was conducted from July 2009 to August 2011 on 20 patients with GVs. The age range was from 22 to 56 years, with a mean age of 39.8±7.85 years. There were 14 men (70%) and 6 women (30%). Fourteen patients (70%) showed complete obliteration of GVs after one session of treatment, whereas 6 patients (30%) had unsatisfactory results and were subjected to another session. GVs were completely obliterated after the second session in 4 patients. Two cases of recurrence of GVs were operated on. This new technique enabled us to inject GVs with a suitable amount of glue material under direct vision without harming the endoscope. Use of this procedure is recommended in patients fit for surgery and those who had failed endoscopic injection sclerotherapy.

    Thirty-two patients with CT-documented primary brainstem haemorrhage were reviewed retrospectively to obtain a clearer overall clinical picture, especially of the severely disabled survivors. They were divided into 3 groups according to outcome: eleven cases (Group 1) died within 1 month following haemorrhage, 11 cases (Group 2) survived but became bedridden, necessitating full living support, and 10 cases (Group 3) showed minimal neurological deficits and resumed normal activities. Owing to CT and improved critical care, the survival rate was 66% for the whole series. Group 2 comprised 34% of all cases. These patients were mostly alert, quadruplegic, and communicated only with great difficulty. The most common initial symptoms and CT finding in each group were as follows; Group 1: unconsciousness, respiratory disturbance, negative light reflex, tachycardia, and haematoma greater than 3.0 cm; Group 2: disturbance of consciousness, respiratory disturbance, positive light reflex, normal heart rate, and 2.0 greater than haematoma less than 3.5 cm; and Group 3: alertness or only slight disturbance of consciousness, normal respiration, positive light reflex, normal heart rate, haematoma less than 2.5 cm. Although there is an overlap among them, these findings will be useful to distinguish the three groups from each other. Patients with disturbance of consciousness, respiratory disturbance, positive light reflex, normal heart rate, and 2.0 greater than haematoma less than 3.5 cm, have a chance to survive, but in severely disabled condition, if they were treated with vigorous intensive care in the acute stage.

    Objective To provide regional estimates of the prevalence of maternal haemorrhage and explore the effect of methodological differences between studies on any observed regional variation. Methods We conducted a systematic review of the prevalence of maternal haemorrhage, defined as blood loss greater than or equal to 1) 500 ml or 2) 1000 ml in the antepartum, intrapartum or postpartum period. We obtained regional estimates of the prevalence of maternal and severe maternal haemorrhage by conducting meta-analyses and used meta-regression to explore potential sources of between-study heterogeneity. Findings No studies reported the prevalence of antepartum haemorrhage (APH) according to our definitions. The prevalence of postpartum haemorrhage (PPH) (blood loss ≥500 ml) ranged from 7.2% in Oceania to 25.7% in Africa. The prevalence of severe PPH (blood loss ≥1000 ml) was highest in Africa at 5.1% and lowest in Asia at 1.9%. There was strong evidence of between-study heterogeneity in the prevalence of PPH and severe PPH in most regions. Meta-regression analyses suggested that region and method of measurement of blood loss influenced prevalence estimates for both PPH and severe PPH. The regional patterns changed after adjusting for the other predictors of PPH indicating that, compared with European women, Asian women have a lower prevalence of PPH. Conclusions We found evidence that Asian women have a very low prevalence of PPH compared with women in Europe. However, more reliable estimates will only be obtained with the standardisation of the measurement of PPH so that the data from different regions are comparable. PMID:22844432

    We describe the long-term follow-up of a child with recurrent hemoptysis due to severe pulmonary vein stenosis decompressing via collaterals to esophageal varices. Case report SETTING: Tertiary children's hospital PATIENT: Single child through ages 2- to 11-year old INTERVENTIONS: The child underwent cutting balloon angioplasty, bare metal stenting, and implantation of a PTFE-covered stent, all of which failed rapidly. Only after placement of a paclitaxel drug eluting stent did he have prolonged relief from hemoptysis and long-term patency of the treated vein. The stents were serially dilated to keep up with somatic growth of the child, eventually culminating in the need to induce intentional stent fracture. We highlight novel transcatheter techniques to treat this vexing condition, discuss mechanisms of disease treatment and progression, and present the only patient with this rare combination of lesions to have achieved both longstanding pulmonary vein patency and resolution of esophageal varices. © 2017 Wiley Periodicals, Inc.

  4. The ovine fetal endocrine reflex responses to haemorrhage are not mediated by cardiac nerves

    Wood, Charles E

    2002-01-01

    This study was designed to test the hypothesis that cardiac receptors tonically inhibit the secretion of renin, arginine vasopressin (AVP) and adrenocorticotropic hormone (ACTH) in late-gestation fetal sheep. Eight chronically catheterised fetal sheep between 122 and 134 days gestation were subjected to injection or infusion of saline or 4 % procaine into the pericardial space. Fetal blood pressure and heart rate were monitored and fetal blood samples were drawn to measure the response to these injections. Injection of procaine into the pericardial space effectively blocked cardiac nerves, as evidenced by a reduction in the variability of fetal heart rate and by the blockade of reflex reductions in fetal heart rate after intravenous injection of phenylephrine (an α-adrenergic agonist which raises blood pressure). Injection of saline had no discernable effects on any of the measured variables. A single injection of procaine, followed by a slow infusion, produced a transient blockade of cardiac nerves. Multiple injections of procaine produced a sustained blockade of cardiac nerves and a sustained rise in fetal plasma renin activity and ACTH. In none of the experiments did procaine significantly alter fetal plasma AVP concentrations. In 11 fetuses between 121 and 134 days gestation, we combined the cardiac nerve blockade with slow haemorrhage to test the cardiac nerves as mediators of the endocrine response to haemorrhage in utero. Cardiac nerve blockade exaggerated the fetal blood gas response to haemorrhage somewhat but did not significantly alter the magnitude of the ACTH, AVP, or plasma renin activity response to haemorrhage. We conclude that cardiac nerves in the late-gestation fetal sheep have minor influences on plasma renin activity and ACTH in normovolaemic fetuses, but that changes in cardiac nerve activity do not mediate the endocrine responsiveness to haemorrhage.

    Increasing incidence and severity of postpartum haemorrhage, together with postpartum haemorrhage-associated morbidities, have been reported in many high-resource countries. In-depth analysis of such factors in Victorian births since 2002 was lacking. Our aim was to determine the incidence and trends for primary postpartum haemorrhage (World Health Organization and International Classification of Diseases 10th revision, Australian Modification definitions) for all confinements in Victoria, Australia, for the years 2003-2013 and the incidence and trends for severe postpartum haemorrhage (≥1500 mL) for 2009-2013. In this population-based cross-sectional study de-identified data from the Victorian Perinatal Data Collection were analysed for confinements (excluding terminations) from 2003 to 2013 (n = 764 244). Perinatal information for all births ≥20 weeks (or of at least 400 g birthweight if gestation was unknown) were prospectively collected. One in five women (21.8%) who gave birth between 2009 and 2013 experienced a primary postpartum haemorrhage and one in 71 women (1.4%) experienced a severe primary postpartum haemorrhage. The increasing trends in incidence of primary postpartum haemorrhage, severe primary postpartum haemorrhage, blood transfusion, admission to an intensive care or high dependency unit and peripartum hysterectomy were significant (P < 0.001). Women who had an unassisted vaginal birth had the lowest incidence of primary postpartum haemorrhage. The highest incidence was experienced by women who had an unplanned caesarean section birth. Women who had a forceps birth had the highest incidence of severe primary postpartum haemorrhage. The incidence of primary postpartum haemorrhage, severe primary postpartum haemorrhage and associated maternal morbidities have increased significantly over time in Victoria. © 2018 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    This study aims to evaluate the role of unsedated, ultrathin disposable gastroscopy (TDG) against conventional gastroscopy (CG) in the screening and surveillance of gastroesophageal varices (GEVs) in patients with liver cirrhosis. Forty-eight patients (56.4 ± 1.3 years; 38 male, 10 female) with liver cirrhosis referred for screening (n = 12) or surveillance (n = 36) of GEVs were prospectively enrolled. Unsedated gastroscopy was initially performed with TDG, followed by CG with conscious sedation. The 2 gastroscopies were performed by different endoscopists blinded to the results of the previous examination. Video recordings of both gastroscopies were validated by an independent investigator in a random, blinded fashion. Endpoints were accuracy and interobserver agreement of detecting GEVs, safety, and potential cost saving. CG identified GEVs in 26 (54%) patients, 10 of whom (21%) had high-risk esophageal varices (HREV). Compared with CG, TDG had an accuracy of 92% for the detection of all GEVs, which increased to 100% for high-risk GEVs. The interobserver agreement for detecting all GEVs on TDG was 88% (κ = 0.74). This increased to 94% (κ = 0.82) for high-risk GEVs. There were no serious adverse events. Unsedated TDG is safe and has high diagnostic accuracy and interobserver reliability for the detection of GEVs. The use of clinic-based TDG would allow immediate determination of a follow-up plan, making it attractive for variceal screening and surveillance programs.

    Upper gastrointestinal bleeding (UGIB) is defined as bleeding that results from lesions located above the ligament of Treitz and is a common cause for emergency hospital admissions in patients with gastrointestinal disorders. UGIB also increases the risk of morbidity and mortality in patients already hospitalized for other reasons. According to epidemiological surveys of acute UGIB in Iran, peptic ulcer is the most common endoscopic diagnosis. Gastric and duodenal erosion accounts for 16.4%-25% of etiologies. Other relatively common causes of UGIB are variceal hemorrhage, Mallory-Weiss tears, and arterial and venous malformations. However, in 9%-13.3% of patients, the endoscopy is normal. PMID:24829656

    No current data are available on rebleeding and mortality risk in patients who use alcohol excessively and are admitted for non-variceal upper gastrointestinal bleeding (NVUGIB). This information could help in planning interventions and follow-up protocols for these patients. This study provides contemporary data on the long-term outcome after first-time NVUGIB in alcohol abusers (AAs) compared to non-abusers (NAs). Consecutive patients hospitalized for their first acute gastrointestinal bleeding from 2009 through 2011 were retrospectively recorded and categorized as AA or NA. Risk factors for one-year mortality and rebleeding were identified, and patients were further monitored for long-term mortality until 2015. Alcohol abuse was identified in 19.7% of patients with NVUGIB (n = 518). The one-year rebleeding rate was 16.7% in AAs versus 9.1% in NAs (P = 0.027). Alcohol abuse was associated with a twofold increase in rebleeding risk (P = 0.025); the risk especially increased 6 months after the initial bleeding. The study groups did not differ significantly in 30-day (6.0%) or one-year mortality rates (20.5%). However, there was a tendency for higher overall mortality in AAs than NAs after adjustment of comorbidities. AAs with NVUGIB are at high risk of rebleeding, and mortality is increased in AA patients. A close follow-up strategy and long-term proton pump inhibitor therapy are recommended for AA patients with peptic ulcer or esophagitis.

    Administration of factor VIII (F VIII) concentrates by continuous infusion is now routinely used at several haemophilia centers but almost exclusively for hospitalized patients. We evaluated various aspects of home therapy with continuous infusion of an immunoaffinity purified F VIII concentrate (Monoclate P®, Armour) in patients who would normally have been treated with high doses in bolus injections or with continuous infusion as in-patients. Twenty haemophilia A patients, eight after minor surgery and 12 for serious haemorrhage, received continuous infusion with undiluted F VIII by a minipump for a mean of 0.9 days in the hospital, followed by 3.3 days at home. Infusion bags were exchanged every 2.5 days. No haemorrhagic complications occurred, and five haemorrhages that had been resistant to treatment with bolus injections responded promptly to the continuous infusion. There were no technical problems and patient compliance and acceptance was good. We find this mode of therapy safe, efficacious and convenient for the patients as well as for the staff.

    1996-01-01

    BACKGROUND: Acute asthma during pregnancy is potentially dangerous to the fetus. The aim of this study was to investigate the effect of an acute attack of asthma during pregnancy on the course of pregnancy or delivery, or the health of the newborn infant, and to identify undertreatment as a possible cause of the exacerbations. METHODS: Five hundred and four pregnant asthmatic subjects were prospectively followed and treated. The data on 47 patients with an attack of asthma during pregnancy were compared with those of 457 asthmatics with no recorded acute exacerbation and with 237 healthy parturients. RESULTS: Of 504 asthmatics, 177 patients were not initially treated with inhaled corticosteroids. Of these, 17% had an acute attack compared with only 4% of the 257 patients who had been on inhaled anti-inflammatory treatment from the start of pregnancy. There were no differences between the groups as to length of gestation, length of the third stage of labour, or amount of haemorrhage after delivery. No differences were observed between pregnancies with and without an exacerbation with regard to relative birth weight, incidence of malformations, hypoglycaemia, or need for phototherapy for jaundice during the neonatal period. CONCLUSIONS: Patients with inadequate inhaled anti-inflammatory treatment during pregnancy run a higher risk of suffering an acute attack of asthma than those treated with an anti-inflammatory agent. However, if the acute attack of asthma is relatively mild and promptly treated, it does not have a serious effect on the pregnancy, delivery, or the health of the newborn infant. PMID:8733495

    2009-10-01

    Stroke is the second most common cause of death worldwide and is the complication of hypertension that is most directly linked to blood pressure. Hypertension affects nearly 30% of the world's population; therefore, reducing blood pressure is key for the prevention of stroke. Unlike the established role of hypertension as a risk factor for stroke, the prognostic importance of blood pressure in determining outcome after acute stroke is unclear. The acute hypertensive response occurs in more than 50% of all patients with acute stroke and is associated with poor prognosis. The relation between the outcome of acute stroke and blood pressure is U-shaped, with the best outcome at systolic blood-pressure levels ranging from about 140 to 180 mm Hg. The evidence that decreasing blood pressure in hypertensive patients with acute ischaemic or haemorrhagic stroke improves prognosis needs further confirmation. Whether raising blood pressure to improve perfusion of ischaemic brain areas is beneficial remains even more uncertain. Present guidelines for the management of blood pressure in patients with acute stroke are not evidence-based, but results from ongoing trials might provide more informed recommendations for the future.

    Non-variceal upper gastrointestinal bleeding remains an important emergency condition, leading to significant morbidity and mortality. As endoscopic therapy is the 'gold standard' of management, treatment of these patients can be considered in three stages: pre-endoscopic treatment, endoscopic haemostasis and post-endoscopic management. Since publication of the Asia-Pacific consensus on non-variceal upper gastrointestinal bleeding (NVUGIB) 7 years ago, there have been significant advancements in the clinical management of patients in all three stages. These include pre-endoscopy risk stratification scores, blood and platelet transfusion, use of proton pump inhibitors; during endoscopy new haemostasis techniques (haemostatic powder spray and over-the-scope clips); and post-endoscopy management by second-look endoscopy and medication strategies. Emerging techniques, including capsule endoscopy and Doppler endoscopic probe in assessing adequacy of endoscopic therapy, and the pre-emptive use of angiographic embolisation, are attracting new attention. An emerging problem is the increasing use of dual antiplatelet agents and direct oral anticoagulants in patients with cardiac and cerebrovascular diseases. Guidelines on the discontinuation and then resumption of these agents in patients presenting with NVUGIB are very much needed. The Asia-Pacific Working Group examined recent evidence and recommends practical management guidelines in this updated consensus statement. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

  14. Endoscopic Ultrasound (EUS) for Esophageal and Gastric Varices: How Can it Improve the Outcomes and Reduce Complications of Glue Injection

    PubMed Central

    Bhatia, Vikram

    2012-01-01

    A large part of portal venous system and the paragastric and para-esophageal collateral circulation is within the reach of endoscopic ultrasound (EUS). The EUS is more sensitive than gastroscopy for the detection of gastric varices (GV), and can accurately distinguish GV from thickened gastric folds. Gastric varices are depicted by serpiginous, anechoic, Doppler-positive mural channels, with larger collateral channels visible outside the gastric wall. The EUS has also been used to monitor the completeness of GV obturation after glue injection. There are limited data that this strategy may be clinically beneficial to prevent GV re-bleed. The EUS has been used to deliver glue injections under real-time monitoring into the vascular channels, with or without steel coils as scaffolding for the glue. The potential advantages of this technique include a straight scope position, lack of hindrance from pooled blood in gastric fundus, smaller glue volume requirements, and precise intra-vascular placement of glue with avoidance of intramural injections, and reduced embolic complications.

    Acquired amegakaryocytic thrombocytopenic purpura is a very rare condition characterized by severe thrombocytopenia linked to the reduction or disappearance of megakaryocytes in the bone marrow. It may be primary idiopathic or secondary to many pathological conditions including hematologic disorders. We report the case of a 24-year-old patient admitted for haemorrhagic syndrome caused by immunological thrombocytopenic purpura. The diagnosis was acquired amegakaryocytosis after the failure of corticotherapy and the performance of myelography. The patient was treated with ciclosporin with rapid progression to acute myeloblastic leukemia. The progression of acquired amegakaryocytosis to acute leukemia is reported but it is generally not so rapid and above all it is preceded by myelodysplastic syndrome or medullary aplasia. This study highlights the importance of a close follow-up of these pathologies with a benign-like appearance.

    Spontaneous intracerebral haemorrhage (ICH) is more common in Asia than in western countries, and has a high mortality rate. A simple prognostic score for predicting grave prognosis of ICH is lacking. Our objective was to develop a simple and reliable score for most physicians. ICH patients from seven Asian countries were enrolled between May 2000 and April 2002 for a prospective study. Clinical features such as headache and vomiting, vascular risk factors, Glasgow coma scale (GCS), body temperature (BT), blood pressure on arrival, location and size of haematoma, intraventricular haemorrhage (IVH), hydrocephalus, need for surgical treatment, medical treatment, length of hospital stay and other complications were analyzed to determine the outcome using a modified Rankin scale (MRS). Grave prognosis (defined as MRS of 5-6) was judged on the discharge date. 995 patients, mean age 59.5 +/- 14.3 years were analyzed, after exclusion of incomplete data in 87 patients. 402 patients (40.4%) were in the grave prognosis group (MRS 5-6). Univariable analysis and then multivariable analysis showed only four statistically significant predictors for grave outcome of ICH. They were fever (BT > or = 37.8 degrees c), low GCS, large haematoma and IVH. The grave prognosis on spontaneous intracerebral haemorrhage (GP on STAGE) score was derived from these four factors using a multiple logistic model. A simple and pragmatic prognostic score for ICH outcome has been developed with high sensitivity (82%) and specificity (82%). Furthermore, it can be administered by most general practitioners. Validation in other populations is now required.

  18. Fifty-three years' experience with randomized clinical trials of emergency portacaval shunt for bleeding esophageal varices in Cirrhosis: 1958-2011.

    Emergency treatment of bleeding esophageal varices (BEV) consists mainly of endoscopic and pharmacologic measures, with transjugular intrahepatic portal-systemic shunt (TIPS) performed when bleeding is not controlled. Surgical shunt has been relegated to salvage. At the University of California, San Diego, Medical Center, our group has conducted 10 studies of emergency portacaval shunt (EPCS) during 46 years. To describe 2 randomized clinical trials (RCTs) conducted from 1988 to 2011 in unselected consecutive patients who received emergency treatment for BEV. In RCT No. 1, a total of 211 unselected consecutive patients with cirrhosis and acute BEV were randomized to emergency endoscopic sclerotherapy (EEST) (n=106) or EPCS (n=105). In RCT No. 2, a total of 154 unselected consecutive patients with cirrhosis and acute BEV were randomized to TIPS (n=78) or EPCS (n=76). Diagnostic workup was completed within 6 hours of initial contact, and primary treatment was initiated within 8 to 12 hours. Regular follow-up for up to 10 years was accomplished in 100% of the patients. In RCT No. 1, EEST or EPCS; in RCT No. 2, TIPS or EPCS. The 2 groups were compared with regard to survival, control of bleeding, portal-systemic encephalopathy, and direct cost of care. RESULTS Distribution in Child risk classes was almost identical. One-third of patients were in Child class C. Permanent control of bleeding was achieved by EEST in only 20% of the patients and by TIPS in only 22%. In contrast, EPCS permanently controlled bleeding in 97% and 100% of the patients in RCT No. 2 and RCT No. 1, respectively (P<.001). Survival was significantly greater following EPCS than after EEST and TIPS (P<.001). Median survival was more than 10 years following EPCS compared with 1.99 years after TIPS. Occlusion of TIPS was demonstrated in 84% of the patients, 63% of whom underwent TIPS revision, which failed in 80% of the cases. Recurrent portal-systemic encephalopathy developed in 35% of the patients who

    Postpartum haemorrhage (PPH) remains a significant cause of maternal morbidity and mortality in both developed and developing countries. In some instances, PPH can be anticipated and recent improvements in obstetric imaging techniques allow earlier and more reliable diagnosis of abnormalities associated with haemorrhage such as morbid placentation. However, the majority of PPH is unpredicted. Good practice notes published by the Royal College of Obstetricians and Gynaecologists state interventional radiology should be used as emergency intervention in PPH and should be considered when primary management has failed allowing arteries to be embolised to achieve haemostasis. Through collaboration between interventional radiology and maternity, appropriate guidelines need to be developed, on both emergency and elective of interventional radiology in the prevention and management of PPH. As there is mapping for neonatal services, in the future there should be consideration to develop obstetric trauma units. Maternity units which lack facilities for interventional radiology would be able to refer their cases (like placenta accreta) for safe management in units with 24 h interventional radiology services.

    Limited data exist on health-related quality of life (HRQoL) after intracerebral haemorrhage (ICH). We aimed to determine baseline factors associated with HRQoL among participants of the pilot and main phases of the Intensive Blood Pressure Reduction in Acute Cerebral Haemorrhage Trials (INTERACT 1 and 2). The INTERACT studies were randomised controlled trials of early intensive blood pressure (BP) lowering in patients with ICH (<6 hours) and elevated systolic BP (150-220 mm Hg). HRQoL was determined using the European Quality of Life Scale (EQ-5D) at 90 days, completed by patients or proxy responders. Binary logistic regression analyses were performed to identify factors associated with poor overall HRQoL. 2756 patients were included. Demographic, clinical and radiological factors associated with lower EQ-5D utility score were age, randomisation outside of China, antithrombotic use, high baseline National Institutes of Health Stroke Scale (NIHSS) score, larger ICH, presence of intraventricular extension and use of proxy responders. High (≥14) NIHSS score, larger ICH and proxy responders were associated with low scores in all five dimensions of the EQ-5D. The NIHSS score had a strong association with poor HRQoL (p<0.001). Female gender and antithrombotic use were associated with decreased scores in dimensions of pain/discomfort and usual activity, respectively. Poor HRQoL was associated with age, comorbidities, proxy source of assessment, clinical severity and ICH characteristics. The strongest association was with initial clinical severity defined by high NIHSS score. NCT00226096 and NCT00716079; Post-results. Published by the BMJ Publishing Group Limited.

    Severe postpartum haemorrhage after vaginal delivery: a statistical process control chart to report seven years of continuous quality improvement To use statistical process control charts to describe trends in the prevalence of severe postpartum haemorrhage after vaginal delivery. This assessment was performed 7 years after we initiated a continuous quality improvement programme that began with regular criteria-based audits Observational descriptive study, in a French maternity unit in the Rhône-Alpes region. Quarterly clinical audit meetings to analyse all cases of severe postpartum haemorrhage after vaginal delivery and provide feedback on quality of care with statistical process control tools. The primary outcomes were the prevalence of severe PPH after vaginal delivery and its quarterly monitoring with a control chart. The secondary outcomes included the global quality of care for women with severe postpartum haemorrhage, including the performance rate of each recommended procedure. Differences in these variables between 2005 and 2012 were tested. From 2005 to 2012, the prevalence of severe postpartum haemorrhage declined significantly, from 1.2% to 0.6% of vaginal deliveries (p<0.001). Since 2010, the quarterly rate of severe PPH has not exceeded the upper control limits, that is, been out of statistical control. The proportion of cases that were managed consistently with the guidelines increased for all of their main components. Implementation of continuous quality improvement efforts began seven years ago and used, among other tools, statistical process control charts. During this period, the prevalence of severe postpartum haemorrhage after vaginal delivery has been reduced by 50%. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

  3. Heme oxygenase-1 exacerbates early brain injury after intracerebral haemorrhage

    2008-01-01

    Because heme oxygenase (HO) is the rate limiting enzyme in the degradation of the pro-oxidant hemin/heme from blood, here we investigated the contribution of the inducible HO-1 to early brain injury produced by intracerebral haemorrhage (ICH). We found that after induction of ICH, HO-1 proteins were highly detectable in the peri-ICH region predominantly in microglia/macrophages and endothelial cells. Remarkably, the injury volume was significantly smaller in HO-1 knockout (HO-1−/−) mice than in wild-type controls 24 and 72 h after ICH. Although the brain water content did not appear to be significantly different, the protection in HO-1−/− mice was associated with a marked reduction in ICH-induced leucocyte infiltration, microglia/macrophage activation and free radical levels. These data reveal a previously unrecognized role of HO-1 in early brain injury after ICH. Thus, modulation of HO-1 signalling should be assessed further in clinical settings, especially for haemorrhagic states. PMID:17525142

    Esophageal variceal bleeding is one of the most frequent and gravest complications of liver cirrhosis, directly life-threatening. By monitoring certain clinical and laboratory hepatocellular insufficiency parameters (Child-Pugh score), it is possible to determine prognosis in patients who are bleeding and evaluate further therapy. Recently, the Model for the End-Stage Liver Disease (MELD) has been proposed as a tool to predict mortality risk in cirrhotic patients. The aim of the study was to evaluate survival prognosis of cirrhotic patients by the MELD and Child-Pugh scores and to analyze the MELD score prognostic value in patients with both liver cirrhosis and variceal bleeding. We retrospectively evaluated the survival rate of a group of 100 cirrhotic patients of a median age of 57 years. The Child-Pugh score was calculated and the MELD score was computed according to the original formula for each patient. We also analysed clinical and laboratory hepatocellular insufficiency parameters in order to examine their connection with a 15-month survival. The MELD values were correlated with the Child-Pugh scores. The Student's t-test was used for statistical analysis. Twenty-two patients died within 15-months followup. Age and gender did not affect survival rate. The Child-Pugh and MELD scores, as well as ascites and encephalopathy significantly differed between the patients who survived and those who died (p < 0.0001). The International Normalized Ratio (INR) values, serum creatinine and bilirubin were significantly higher, and albumin significantly lower in the patients who died (p < 0.0001). The MELD score was significantly higher in the group of patients who died due to esophageal variceal bleeding (p < 0.0001). In cirrhotic patients the MELD score is an excellent survival predictor at least as well as the Child-Pugh score. Increase in the MELD score is associated with decrease in residual liver function.

    Adhesive small bowel obstruction (ASBO) is common after abdominal surgery. Water soluble contrast agents (WSCA) such as Gastrografin have been demonstrated to be safe and effective in predicting resolution of ASBO with conservative management while decreasing the time to resolution, decreasing the need for surgery and reducing overall length of stay. Few adverse effects have been reported. To the authors knowledge this is the first report of haemorrhagic gastritis following administration of Gastrografin for ASBO. We present a case of haemorrhagic gastritis following Gastrografin administration in a 69-year-old male with adhesive small bowel obstruction who was managed conservatively with a good outcome. The report complies with the criteria outlined in the SCARE statement (Product Information Gastrografin [Product information], 2013). The characteristics, mechanism of action, safety profile and efficacy of Gastrografin in ASBO are discussed along with the possible mechanisms underlying the haemorrhagic gastritis. This patient at high risk of gastropathy experienced haemorrhagic gastritis following administration of Gastrografin for adhesive small bowel obstruction. WSCA such as Gastrografin are usually safe and effective in ASBO however caution may be warranted in patients at high risk of gastropathy. Copyright © 2017 The Authors. Published by Elsevier Ltd..

    The aim of this study was to use electrical impedance tomography (EIT) to detect and image acute intracranial haemorrhage (ICH) in an animal model. Blood was infused into the frontal lobe of the brains of anaesthetized piglets and impedance was measured using 16 electrodes placed in a circle on the scalp. The EIT images were constructed using a filtered back-projection algorithm. The mean of all the pixel intensities within a region of interest--the mean resistivity value (MRV)--was used to evaluate the relative impedance changes in the target region. A symmetrical index (SI), reflecting the relative impedance on both sides of the brain, was also calculated. Changes in MRV and SI were associated with the injection of blood, demonstrating that EIT can successfully detect ICH in this animal model. The unique features of EIT may be beneficial for diagnosing ICH early in patients after cranial surgery, thereby reducing the risk of complications and mortality.

    Hematemesis and acute postsurgical upper gastrointestinal hemorrhage are common emergent on-call consultations for the interventional radiologist. Upper GI bleleding (UGIB) is a relatively frequent problem. The incidence and mortality vary among patient populations, but studies have shown an overall incidence ranging from 36-172 cases per 100,000 adults per year, with a mortality rate of 5%-14%. The incidence is significantly higher in men. Peptic ulcer disease is the predominant etiology, responsible for 28%-59% of UGIB. Other causes include varices, mucosal erosive disease, Mallory-Weiss syndrome, and malignancy. After assessment of hemodynamic status and airway stability with resuscitative efforts as needed, initial consultation with gastroenterology for endoscopic evaluation and treatment is well regarded as the initial therapeutic strategy. Angiography with embolization and interventional techniques directed at managing variceal hemorrhage have emerged as very capable second-line strategies for patients who have failed endoscopic therapy. In certain circumstances, the interventional radiologist may be called upon as the first line, notably for patients who have had recent surgical intervention or who have extraluminal hemorrhage. As the role of the interventional radiologist in the evaluation and treatment of UGIB continues to evolve, familiarity and knowledge of how to deal with these urgent and emergent clinical scenarios becomes paramount.

  9. Gastrointestinal Bleeding in Cirrhotic Patients with Portal Hypertension

    PubMed Central

    Biecker, Erwin

    2013-01-01

    Gastrointestinal bleeding related to portal hypertension is a serious complication in patients with liver cirrhosis. Most patients bleed from esophageal or gastric varices, but bleeding from ectopic varices or portal hypertensive gastropathy is also possible. The management of acute bleeding has changed over the last years. Patients are managed with a combination of endoscopic and pharmacologic treatment. The endoscopic treatment of choice for esophageal variceal bleeding is variceal band ligation. Bleeding from gastric varices is treated by injection with cyanoacrylate. Treatment with vasoactive drugs as well as antibiotic treatment is started before or at the time point of endoscopy. The first-line treatment for primary prophylaxis of esophageal variceal bleeding is nonselective beta blockers. Pharmacologic therapy is recommended for most patients; band ligation is an alternative in patients with contraindications for or intolerability of beta blockers. Treatment options for secondary prophylaxis include variceal band ligation, beta blockers, a combination of nitrates and beta blockers, and combination of band ligation and pharmacologic treatment. A clear superiority of one treatment over the other has not been shown. Bleeding from portal hypertensive gastropathy or ectopic varices is less common. Treatment options include beta blocker therapy, injection therapy, and interventional radiology. PMID:27335828

    A retrospective review was undertaken of all patients referred for computed tomography (CT) scans of the head for acute onset of confusion, not consequent on head trauma, during the period June 1, 2004 to May 31, 2007. Data were obtained by Microsoft Word search of the reports of the Radiology Department of the University Hospital of the West Indies, Kingston, Jamaica. Two hundred and twenty-one patients were reviewed: 103 men and 118 women. The mean age of the sample was 64 years; 168 patients (76%) were 50 years old or older. Computed tomography scans were reported normal in 170 (76.9%) patients; 45 patients (20.4%) had definite acute intracranial CT findings. Findings were equivocal in three patients (1.4%) and unavailable for three (1.4%); 23.2% and 15.6% of patients above and below the age of 50 years respectively showed acute abnormalities on CT The most common acute finding on CT scan was an ischaemic infarct (68%). Other abnormalities included intracerebral haemorrhage and metastases 6.2% each, toxoplasmosis and primary brain tumour 4.2% each and subdural haematoma and meningitis 2.1% each. The diagnoses of toxoplasmosis were made based on appearances typical of toxoplasmosis on CT scans in patients whose request stated that they were HIV positive. In the sample reviewed, most patients who presented with acute confusion were above the age of 50 years. Overall, 20.4% of patients from all age groups had acute abnormalities on CT with a relative higher proportion, 23.2% versus 15.6% of those over 50 years, having acute pathology. The most common abnormality was an ischaemic infarct. This finding is similar to that in developed countries and unlike that seen in other developing countries where infectious aetiologies predominate.

    Although a concern exists that 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors (statins) might increase the risk of intracerebral haemorrhage (ICH), the contribution of these agents to the relationship between serum cholesterol and disease occurrence has been poorly investigated. We compared consecutive patients having ICH with age and sex-matched stroke-free control subjects in a case-control analysis, as part of the Multicenter Study on Cerebral Haemorrhage in Italy (MUCH-Italy), and tested the presence of interaction effects between total serum cholesterol levels and statins on the risk of ICH. A total of 3492 cases (mean age, 73.0±12.7 years; males, 56.6%) and 3492 control subjects were enrolled. Increasing total serum cholesterol levels were confirmed to be inversely associated with ICH. We observed a statistical interaction between total serum cholesterol levels and statin use for the risk of haemorrhage (Interaction OR (IOR), 1.09; 95% CI 1.05 to 1.12). Increasing levels of total serum cholesterol were associated with a decreased risk of ICH within statin strata (average OR, 0.87; 95% CI 0.86 to 0.88 for every increase of 0.26 mmol/l of total serum cholesterol concentrations), while statin use was associated with an increased risk (OR, 1.54; 95% CI 1.31 to 1.81 of the average level of total serum cholesterol). The protective effect of serum cholesterol against ICH was reduced by statins in strictly lobar brain regions more than in non-lobar ones. Statin therapy and total serum cholesterol levels exhibit interaction effects towards the risk of ICH. The magnitude of such effects appears higher in lobar brain regions.

  12. HAEMORRHAGIC SYNDROME IN THE CLINICAL PICTURE OF RADIATION SICKNESS IN DOGS AFFECTED BY POLONIUM (in Russian)

    Mikhailovich, S.M.

    Subcutaneous introduction of polonium to dogs brings about development of radiation sickness with appearance of haemorrhagic syndrome, which is characterized by disturbed process of blood coagulation, thrombocytopenia, decreased prothrombin value of the blood, increased permeability of capillaries. The clinical picture of the usually developed affection corresponds to the well known symptomatology, described in literature. Indicators of the haemorrhagic syndrome (blood coagulation, prothrombin value, permeabillty and stability of capillaries) appear in animals earlier than the clinical manifestations of this syndrome.

  13. Surgical Craniotomy for Intracerebral Haemorrhage.

    PubMed

    Mendelow, A David

    2015-01-01

    Craniotomy is probably indicated for patients with superficial spontaneous lobar supratentorial intracerebral haemorrhage (ICH) when the level of consciousness drops below 13 within the first 8 h of the onset of the haemorrhage. Once the level drops below 9, it is probably too late to consider craniotomy for these patients, so clinical vigilance is paramount. While this statement is only backed up by evidence that is moderately strong, meta-analysis of available data suggests that it is true in the rather limited number of patients with ICH. Meta-analyses like this can often predict the results of future prospective randomised controlled trials a decade or more before the trials are completed and published. Countless such examples exist in the literature, as is the case for thrombolysis in patients with myocardial infarction in the last millennium: meta-analysis determined the efficacy more than a decade BEFORE the last trial (ISIS-2) confirmed the benefit of thrombolysis for myocardial infarction. Careful examination of the meta-analysis' Forest plots in this chapter will demonstrate why this statement is made at the outset. Other meta-analyses of surgery for ICH have also indicated that minimal interventional techniques using topical thrombolysis or endoscopy via burrholes or even twist drill aspiration may be particularly successful for the treatment of supratentorial ICH, especially when the clot is deep seated. Ongoing clinical trials (CLEAR III and MISTIE III) should confirm this in the fullness of time. There are 2 exceptions to these generalisations. First, based on trial evidence, aneurysmal ICH is best treated with surgery. Second, cerebellar ICH represents a special case because of the development of hydrocephalus, which may require expeditious drainage as the intracranial pressure rises. The cerebellar clot will then require evacuation, usually via posterior fossa craniectomy, rather than craniotomy. Technical advances suggest that image-guided surgery

    Endoscopic therapy (ET) is most common method for preventing variceal bleeding in cirrhosis, but the outcomes are not perfect. Recently, transjugular intrahepatic portosystemic shunt (TIPS) is introduced into clinical practice. However, the beneficial effects of TIPS compared to ET on cirrhotic patients is unknown. The aim of this study was to evaluate and compare the effects of TIPS with those of the most frequently used ET for prevention of variceal rebleeding (VRB) in liver cirrhosis. The Pub-Med, EMBASE, and Cochrane Library databases were searched from inception to February 2017. The primary study outcomes included the incidence of VRB, all-cause mortality, bleeding-related death, and the incidence of post-treatment hepatic encephalopathy (PTE). The odds ratios (ORs) with 95% confidence intervals (CI) were pooled for dichotomous variables. Subgroup analyses were performed. Twenty-four studies were eligible and they included 1120 subjects treated with TIPS and 1065 subjects treated with ET. Although there was no significant difference in survival and PTE, TIPS was superior to ET in decreasing the incidence of VRB (OR=0.27; 95% CI, 0.19-0.39, P<0.00001), and decreasing the incidence of bleeding-related death (OR=0.21; 95% CI, 0.13-0.32, P<0.00001). Subgroup analysis found a lower mortality (OR=0.48; 95% CI, 0.23-0.97; P=0.04) without any increased incidence of PTE (OR=1.37; 95% CI, 0.75-2.50; P=0.31) in the studies of a greater proportion (≥40%) of patients with Child-Pugh class C cirrhosis receiving TIPS, and TIPS with covered stent did not increase the risk of PTE compared to ET (OR=1.52, 95% CI =0.82-2.80, P=0.18). It was concluded that TIPS with covered stent might be considered the preferred choice of therapy in patients with severe liver disease for secondary prophylaxis.

    Down syndrome (DS), which arises from trisomy of chromosome 21, is associated with deposition of large amounts of amyloid within the central nervous system. Amyloid accumulates in two compartments: as plaques within the brain parenchyma and in vessel walls of the cerebral microvasculature. The parenchymal plaque amyloid is thought to result in an early onset Alzheimer’s disease (AD) dementia, a phenomenon so common amongst people with DS that it could be considered a defining feature of the condition. The amyloid precursor protein ( APP) gene lies on chromosome 21 and its presence in three copies in DS is thought to largely drive the early onset AD. In contrast, intracerebral haemorrhage (ICH), the main clinical consequence of vascular amyloidosis, is a more poorly defined feature of DS. We review recent epidemiological data on stroke (including haemorrhagic stroke) in order to make comparisons with a rare form of familial AD due to duplication (i.e. having three copies) of the APP region on chromosome 21, here called ‘dup-APP’, which is associated with more frequent and severe ICH. We conclude that although people with DS are at increased risk of ICH, this is less common than in dup-APP, suggesting the presence of mechanisms that act protectively. We review these mechanisms and consider comparative research into DS and dup-APP that may yield further pathophysiological insight. PMID:27239286

    Spontaneous intracerebral haemorrhage (ICH) is a relatively common fatal disease, with an overall global incidence estimated at 24.6 per 100,000 person-years. Given the high degree of morbidity and mortality associated with ICH, therapies that may have neuroprotective effects are of increasing interest to clinicians. In this last context, cell therapies offer the promise of improving the disease course which cannot be addressed adequately by existing treatments. The aim of this review is to evaluate the protective effects and molecular mechanisms of mesenchymal stem cells (MSCs) on haemorrhagic brain following ICH. We also discuss possible emerging therapeutic approaches worth of further research. The available literature on the therapeutic potential of MSCs in ICH animal models clearly demonstrated that MSCs enhance the functional recovery and reduce the volume of the infarct size exerting anti-inflammatory and angiogenic properties. However, the quality of the original articles investigating the efficacy of stem cell therapies in ICH animal models is still poor and the lack of ICH clinical trial does not permit to reach any relevant conclusions. Further studies have to be implemented in order to achieve standardized methods of MSCs isolation, characterization and administration to improve ICH treatments with MSCs or MSC-derived products.

    BACKGROUND Aspartate aminotransferase-to-platelet ratio index (APRI), aspartate aminotransferase-to-alanine aminotransferase ratio (AAR), FIB-4, fibrosis index (FI), and King scores might be alternatives to the use of upper gastrointestinal endoscopy for the diagnosis of esophageal varices (EVs) in liver cirrhosis. This study aimed to evaluate their diagnostic accuracy in predicting the presence and severity of EVs in liver cirrhosis. MATERIAL AND METHODS All patients who were consecutively admitted to our hospital and underwent upper gastrointestinal endoscopy between January 2012 and June 2014 were eligible for this retrospective study. Areas under curve (AUCs) were calculated. Subgroup analyses were performed according to the history of upper gastrointestinal bleeding (UGIB) and splenectomy. RESULTS A total of 650 patients with liver cirrhosis were included, and 81.4% of them had moderate-severe EVs. In the overall analysis, the AUCs of these non-invasive scores for predicting moderate-severe EVs and presence of any EVs were 0.506-0.6 and 0.539-0.612, respectively. In the subgroup analysis of patients without UGIB, their AUCs for predicting moderate-severe varices and presence of any EVs were 0.601-0.664 and 0.596-0.662, respectively. In the subgroup analysis of patients without UGIB or splenectomy, their AUCs for predicting moderate-severe varices and presence of any EVs were 0.627-0.69 and 0.607-0.692, respectively. CONCLUSIONS APRI, AAR, FIB-4, FI, and King scores had modest diagnostic accuracy of EVs in liver cirrhosis. They might not be able to replace the utility of upper gastrointestinal endoscopy for the diagnosis of EVs in liver cirrhosis.

    Although thrombocytopenia is known to be associated with pathogenesis of retinopathy of prematurity (ROP), immune thrombocytopenic purpura (ITP) is rare in infancy and not reported to occur with ROP. A preterm infant with aggressive posterior ROP developed bilateral massive subconjunctival haemorrhage after scleral indentation during screening. On evaluation, the infant was found to have severe ITP. Following intravenous transfusion of platelets and immunoglobulin, platelet counts improved and subconjunctival haemorrhage resolved over time. This case highlights the unusual presentation of ITP and also discusses the association of thrombocytopenia with ROP. Ophthalmologists should get prompt haematological work-up of such occurrences. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017. All rights reserved.

    To establish the effects of a meal on portal venous flow and the prognostic value of this parameter, 46 patients with chronic liver disease and 28 healthy subjects were examined with duplex Doppler before and after a meal. The measurements were completed in 40 patients and 21 healthy subjects. Postprandial portal venous diameter, blood velocity and quantitative flow were measured for 60 min. Mean baseline values were: 11.4 mm versus 10.2 mm (p = 0.019), 10.8 cm.s-1 versus 13.4 cm.s-1 (p = 0.015) and 668 ml.min-1 versus 646 ml.min-1 (p = 0.7) respectively. Spleen size was 15.0 cm versus 10.6 cm (p = 0.0001) respectively. Postprandial diameter, velocity and flow increased significantly in patients and controls (p = 0.0001 for all). Mean postprandial flow could best be described by a polynomial equation with a parabolic curve. Patients' curves were more blunted than controls', with significantly different regression constants (p = 0.025 and p = 0.029). All subjects were followed up for survival and variceal haemorrhage. The mean follow-up time was 47 months. Early maximum postprandial velocity (p = 0.041) and large spleen size (p = 0.002) were significantly related to an unfavourable prognosis for survival. Early maximum velocity was also related to increased variceal haemorrhage. This study shows that postprandial portal venous flow is blunted in patients with chronic liver disease. Postprandial portal venous flow may have prognostic significance.

    We examined 33 patients with left intracerebral haemorrhage to investigate the relations to buccofacial apraxia (BFA). BFA was present in 18 cases at 1 month and disappeared in 3 cases and persisted in 15 cases at 6 month from the onset. The existence of BFA seems to be partially dependent the haematoma volume which may cause the organic damage in lenticulate nucleus, insula, posterior limb or internal capsule and anterior portion of paraventricle white matter. All patients with BFA had aphasia (Broca 6, Wernicke 1, Total 10, Amnestic 1). Aphasia of the patients with transient BFA improved as well as the patients without BFA after BFA disappeared. We suspected that improvement or aphasia might be affected by BFA.

    BACKGROUND For patients with esophagogastric varices secondary to portal hypertension due to liver cirrhosis, portosystemic shunts and devascularization have become the most commonly used treatment methods. We have developed a novel surgical approach for the treatment of patients with cirrhotic portal hypertension, selective decongestive devascularization, and shunt of the gastrosplenic region (SDDS-GSR). This aim of this study was to compare the efficacy and safety of SDDS-GSR with splenectomy with pericardial devascularization (SPD). MATERIAL AND METHODS A retrospective study was undertaken between 2006 and 2013 and included 110 patients with cirrhotic portal hypertension, 34 of whom underwent SDDS-GSR; 76 patients underwent SPD. Kaplan-Meier analysis was used to evaluate clinical outcomes, mortality, the incidence of re-bleeding, encephalopathy, and portal venous system thrombosis (PVST). RESULTS Postoperatively portal venous pressure decreased by 20% in both groups. The long-term incidence of re-bleeding and PVST was significantly lower in the SDDS-GSR group compared with the SPD group (P=0.018 and P=0.039, respectively). CONCLUSIONS This preliminary retrospective study has shown that SDDS-GSR was an effective treatment for patients with esophagogastric varices secondary to portal hypertension that may be used as a first-line treatment to prevent variceal bleeding and lower the incidence of PVST.

    Tranexamic acid can prevent death due to bleeding after trauma and post-partum haemorrhage. We aimed to assess whether tranexamic acid reduces haematoma expansion and improves outcome in adults with stroke due to intracerebral haemorrhage. We did an international, randomised placebo-controlled trial in adults with intracerebral haemorrhage from acute stroke units at 124 hospital sites in 12 countries. Participants were randomly assigned (1:1) to receive 1 g intravenous tranexamic acid bolus followed by an 8 h infusion of 1 g tranexamic acid or a matching placebo, within 8 h of symptom onset. Randomisation was done centrally in real time via a secure website, with stratification by country and minimisation on key prognostic factors. Treatment allocation was concealed from patients, outcome assessors, and all other health-care workers involved in the trial. The primary outcome was functional status at day 90, measured by shift in the modified Rankin Scale, using ordinal logistic regression with adjustment for stratification and minimisation criteria. All analyses were done on an intention-to-treat basis. This trial is registered with the ISRCTN registry, number ISRCTN93732214. We recruited 2325 participants between March 1, 2013, and Sept 30, 2017. 1161 patients received tranexamic acid and 1164 received placebo; the treatment groups were well balanced at baseline. The primary outcome was assessed for 2307 (99%) participants. The primary outcome, functional status at day 90, did not differ significantly between the groups (adjusted odds ratio [aOR] 0·88, 95% CI 0·76-1·03, p=0·11). Although there were fewer deaths by day 7 in the tranexamic acid group (101 [9%] deaths in the tranexamic acid group vs 123 [11%] deaths in the placebo group; aOR 0·73, 0·53-0·99, p=0·0406), there was no difference in case fatality at 90 days (250 [22%] vs 249 [21%]; adjusted hazard ratio 0·92, 95% CI 0·77-1·10, p=0·37). Fewer patients had serious adverse events after tranexamic

    The molecular mechanisms behind aneurysmal subarachnoid haemorrhage (aSAH) are still poorly understood. Expression patterns of miRNAs may help elucidate the post-transcriptional gene expression in aSAH. Here, we evaluate the global miRNAs expression profile (miRnome) of patients with aSAH to identify potential biomarkers. We collected 33 peripheral blood samples (27 patients with cerebral aneurysm, collected 7 to 10 days after the haemorrhage, when usually is the cerebral vasospasm risk peak, and six controls). Then, were performed small RNA sequencing using an Illumina Next Generation Sequencing (NGS) platform. Differential expression analysis identified eight differentially expressed miRNAs. Among them, three were identified being up-regulated, and five down-regulated. miR-486-5p was the most abundant expressed and is associated with poor neurological admission status. In silico miRNA gene target prediction showed 148 genes associated with at least two differentially expressed miRNAs. Among these, THBS1 and VEGFA, known to be related to thrombospondin and vascular endothelial growth factor. Moreover, MYC gene was found to be regulated by four miRNAs, suggesting an important role in aneurysmal subarachnoid haemorrhage. Additionally, 15 novel miRNAs were predicted being expressed only in aSAH, suggesting possible involvement in aneurysm pathogenesis. These findings may help the identification of novel biomarkers of clinical interest.

    Leptospirosis is a zoonotic infection associated with severe diseases such as leptospirosis pulmonary haemorrhage syndrome (LPHS). The cause of pulmonary haemorrhage is unclear. Understanding which mechanisms and processes are involved in LPHS will be important in treatment regimens under development for this life-threatening syndrome. In the present study, we evaluated 30 lung specimens from LPHS patients and seven controls using histology and immunohistochemistry (detection of IgM, IgG, IgA and C3) in order to describe the pathological features associated with this syndrome. Immunoglobulin deposits were detected on the alveolar surface in 18/30 LPHS patients. Three staining patterns were observed for the immunoglobulins and C3 in the lung tissues of LPHS patients: AS, delicate linear staining adjacent to the alveolar surface, which was indicative of a membrane covering the luminal surface of type I and II pneumocyte cells; S, heterogeneous staining which was sporadically distributed along the alveolar septum; and IA, weak, focal intra-alveolar granular staining. Human LPHS is associated with individual and unique histological patterns that differ from those of other causes of pulmonary haemorrhage. In the present study, it was found that the linear deposition of immunoglobulins (IgA, IgG and IgM) and complement on the alveolar surface may play a role in the pathogenesis of pulmonary haemorrhage in human leptospirosis.

    Multiple CT-derived biomarkers that are predictive of intracerebral haemorrhage (ICH) growth and outcome have been described in the literature, but the extent to which these appear in imaging reports of ICH is unknown. The aim of this retrospective process audit was to determine which of the known predictors of ICH outcome was recorded in reports of the disease, with a view to providing reporting recommendations, as appropriate. We examined the initial CT report of patients diagnosed with ICH presenting to a metropolitan comprehensive stroke centre and meeting inclusion criteria during the audit period between 1 March 2013 and 28 February 2014. Each report was assessed for the inclusion of the following ICH characteristics: the number of measurement dimensions; volume; location; hydrocephalus; shape; density; 'CTA spot sign' (where CTA was performed). A total of 100 patients met audit inclusion criteria. At least one ICH dimension was recorded in 90% of reports; however, 39% did not include the measurements in three dimensions and volume was reported in just 6%. No ICH dimension was recorded in 10% of reports. With the exception of density and shape, reporting of other CT features exceeded 95%. Where CTA was performed (58%), 14 (24%) of 58 reported the 'CTA spot sign' status. In this audit, volume was the most under-reported of the established ICH characteristics predictive of ICH outcome. Readily calculated from multiplanar reformats using the ABC/2 technique, the routine reporting of ICH volume is recommended. More reporting attention to ICH density heterogeneity and shape irregularity is encouraged, given their emerging importance. Where acute CTA is performed, the presence of any dynamic haemorrhage (CTA spot sign) should be reported. © 2016 The Royal Australian and New Zealand College of Radiologists.

    An intracranial haemorrhage is a life threatening medical emergency, yet only a fraction of the patients receive treatment in time, primarily due to the transport delay in accessing diagnostic equipment in hospitals such as Magnetic Resonance Imaging or Computed Tomography. A mono-static microwave head imaging system that can be carried in an ambulance for the detection and localization of intracranial haemorrhage is presented. The system employs a single ultra-wideband antenna as sensing element to transmit signals in low microwave frequencies towards the head and capture backscattered signals. The compact and low-profile antenna provides stable directional radiation patterns over the operating bandwidth in both near and far-fields. Numerical analysis of the head imaging system with a realistic head model in various situations is performed to realize the scattering mechanism of haemorrhage. A modified delay-and-summation back-projection algorithm, which includes effects of surface waves and a distance-dependent effective permittivity model, is proposed for signal and image post-processing. The efficacy of the automated head imaging system is evaluated using a 3D-printed human head phantom with frequency dispersive dielectric properties including emulated haemorrhages with different sizes located at different depths. Scattered signals are acquired with a compact transceiver in a mono-static circular scanning profile. The reconstructed images demonstrate that the system is capable of detecting haemorrhages as small as 1 cm3. While quantitative analyses reveal that the quality of images gradually degrades with the increase of the haemorrhage’s depth due to the reduction of signal penetration inside the head; rigorous statistical analysis suggests that substantial improvement in image quality can be obtained by increasing the data samples collected around the head. The proposed head imaging prototype along with the processing algorithm demonstrates its feasibility

    The authors describe a case of aneurysmal subarachnoid haemorrhage in a 53-year-old man with background of osteogenesis imperfecta (OI). CT brain revealed diffuse subarachnoid haemorrhage (SAH) and cerebral angiogram subsequently confirmed vertebral artery aneurysm rupture leading to SAH. To the authors knowledge this is the first case of vertebral artery aneurysmal SAH described in OI. A previously undiagnosed OI was confirmed by genetic analysis (COL1A1 gene mutation). This aneurysm was successfully treated by endovascular route. Post interventional treatment patient developed stroke secondary to vasospasm. Communicating hydrocephalus, which developed in the process of management, was successfully treated with ventriculo-peritoneal shunt. The aetio-pathogenesis and management of this condition is described. The authors have reviewed the literature and genetic basis of this disease. PMID:22674700

    Magnetic resonance (MR) imaging and computed tomography (CT) are useful for the evaluation of central nervous system (CNS) lupus. This report describes the use of cranial MR and CT in 21 patients with systemic lupus erythematosus (SLE) with acute neuropsychiatric symptoms manifested by headache, seizures, focal neurological deficits, psychosis, or organic brain syndrome. Computed tomography was found to be insensitive and detected only diffuse atrophy (two cases), cerebral infarct (one case), and intracerebral haemorrhage (one case) in the 21 patients. Cranial MR images obtained with a General Electric 1.5 tesla Signa unit detected labile and fixed areas of increased proton intensity interpreted as focal oedema (eight cases), infarct (10 cases), haemorrhage (one), atrophy (seven), and acute sinusitis (two). Focal oedema was characterised by labile, high intensity lesions in the gray or white matter of the cerebellum, cerebrum, or brain stem, which completely resolved after aggressive corticosteroid treatment. Most high intensity reversible or fixed lesions evident on MR were not apparent on cranial CT images. In several patients sequential MR images were valuable in monitoring the efforts of treatment. Although histological confirmation of the high intensity brain lesions apparent on MR is desirable, prior necropsy studies suggest that pathological confirmation may be difficult owing to the paucity of recognisable brain lesions in patients with CNS lupus. It is concluded that for the evaluation of acute neuropsychiatric SLE MR is useful and provides more information than cranial CT. Images PMID:2619353

    Ebola and Marburg viruses are the only members of the Filoviridae family (order Mononegavirales), a group of viruses characterized by a linear, non-segmented, single-strand negative RNA genome. They are among the most virulent pathogens for humans and great apes, causing acute haemorrhagic fever and death within a matter of days. Since their discovery 50 years ago, filoviruses have caused only a few outbreaks, with 2317 clinical cases and 1671 confirmed deaths, which is negligible compared with the devastation caused by malnutrition and other infectious diseases prevalent in Africa (malaria, cholera, AIDS, dengue, tuberculosis …). Yet considerable human and financial resourses have been devoted to research on these viruses during the past two decades, partly because of their potential use as bioweapons. As a result, our understanding of the ecology, host interactions, and control of these viruses has improved considerably. © 2011 The Authors.

    Acute lung injury (ALI) is one of the most serious complications in traumatic patients and is an important part of multiple organ dysfunction syndrome (MODS). Recombinant human brain natriuretic peptide (rhBNP) is a peptide with a wide range of biological activity. In this study, we investigated local changes in oxidative stress and the NF-κB-dependent matrix metalloproteinase-9 (MMP-9) pathway in rats with trauma/haemorrhagic shock (TH/S)-induced ALI and evaluated the effects of pretreatment with rhBNP. Forty-eight rats were randomly divided into four groups: sham operation group, model group, low-dosage rhBNP group and high-dosage rhBNP group (n = 12 for each group). Oxidative stress and MPO activity were measured by ELISA kits. MMP-9 activity was detected by zymography analysis. NF-κB activity was determined using Western blot assay. With rhBNP pretreatment, TH/S-induced protein leakage, increased MPO activity, lipid peroxidation and metalloproteinase (MMP)-9 activity were inhibited. Activation of antioxidative enzymes was reversed. The phosphorylation of NF-κB and the degradation of its inhibitor IκB were suppressed. The results suggested that the protection mechanism of rhBNP is possibly mediated through upregulation of anti-oxidative enzymes and inhibition of NF-κB activation. More studies are needed to further evaluate whether rhBNP is a suitable candidate as an effective inhaling drug to reduce the incidence of TH/S-induced ALI. © 2016 The Authors.

    Since the conception of balloon-occluded retrograde transvenous obliteration (BRTO) of gastric varices 25 years ago, the placement of an indwelling balloon for hours has been central to the BRTO procedure. Numerous variables and variations of the BRTO procedure have been described, including methods to reduce sclerosant, combining percutaneous transhepatic obliteration, varying sclerosant, and using multiple sclerosants within the same procedure. However, the consistent feature of BRTO has always remained the indwelling balloon. Placing an indwelling balloon over hours for the BRTO procedure is a logistical burden that taxes the interventional radiology team and hospital resources. Substituting the balloon with hardware (coils or Amplatzer vascular plugs [AVPs] or both) is technically feasible and its risks most likely correlate with gastrorenal shunt (GRS) size. The current authors use packed 0.018- or 0.035-in coils or both for small gastric variceal systems (GRS size A and B) and AVPs for GRS sizes up to size E (from size A-E). The current authors recommend an indwelling balloon (no hardware substitute) for very large gastric variceal system (GRS size F). Substituting the indwelling balloon for hardware in size F and potentially size E GRS can also be risky. The current article describes the techniques of placing up to 16-mm AVPs through balloon occlusion guide catheters and then deflating the balloon once it has been substituted with the AVPs. In addition, 22-mm AVPs can be placed through sheaths once the balloon occlusion catheters are removed to further augment the 16-mm Amplatzer occlusion. To date, there are no studies describing, let alone evaluating, the clinical feasibility of performing BRTO without indwelling balloons. The described techniques have been successfully performed by the current authors. However, the long-term safety and effectiveness of these techniques is yet to be determined.

    2015-05-01

    Portal hypertension is one of the most serious complications of childhood liver disease, and variceal bleeding is the most feared complication. Most portal hypertension results from cirrhosis but extra hepatic portal vein obstruction is the single commonest cause. Upper gastrointestinal endoscopy endoscopy remains necessary to diagnose gastro-esophageal varices. Families of children with portal hypertension should be provided with written instructions in case of gastrointestinal bleeding. Children with large varices should be considered for primary prophylaxis on a case-by-case basis. The preferred method is variceal band ligation. Children with acute bleeding should be admitted to hospital and treated with antibiotics and pharmacotherapy before urgent therapeutic endoscopy. All children who have bled should then receive secondary prophylaxis. The preferred method is variceal band ligation and as yet there is little evidence to support the use of β-blockers. Children with extrahepatic portal vein obstruction should be assessed for suitability of mesoportal bypass.

    Subarachnoid haemorrhage (SAH) may present with coma and this is known to be associated with aneurysmal origin and blood load. Aneurysmal origin is associated with increased blood load and existing data do not allow us to determine if the association between coma and aneurysmal SAH is wholly due to blood load or if aneurysmal origin has an additional independent effect. The objective of our study is to find if an aneurysmal origin is a predictor of acute onset of coma independent of blood load. A series of consecutive patients with spontaneous SAH were divided into two groups: aneurysmal (aSAH) and non-aneurysmal--angiographically negative SAH (naSAH). Blood load was quantified so that the effect of aneurysmal origin could be resolved from the effect of the amount of blood spilled. Non-parametric regression was used to relate blood load to coma and poor outcome rates for aneurysmal bleeds. We analysed a total of 421 patients presenting during the period 2009-2011. Ninety aneurysmal cases presented with coma, seventy immediately in the early phase and seven shortly after rebleeding. None of the naSAH cases presented with immediate coma and 1 developed delayed coma. Delayed coma was associated with acute hydrocephalus in both groups. Aneurysmal origin was found to be an independent determinant of immediate coma (p=0.02) and poor outcome (p<0.001). Immediate coma and poor outcome in SAH are associated with an aneurysmal origin and do not characterize naSAH. Copyright © 2013 Elsevier B.V. All rights reserved.

    Recently, the application of hemostatic powder to the bleeding site has been used to treat active upper gastrointestinal bleeding (UGIB). We aimed to assess the effectiveness of the polysaccharide hemostatic powder (PHP) in patients with non-variceal UGIB. We reviewed prospectively collected 40 patients with UGIB treated with PHP therapy between April 2016 and January 2017 (PHP group) and 303 patients with UGIB treated with conventional therapy between April 2012 and October 2014 (conventional therapy group). We compared the rate of successful hemostasis and the rebleeding between the two groups after as well as before propensity score matching using the Glasgow-Blatchford score and Forrest classification. Thirty patients treated with the PHP and 60 patients treated with conventional therapy were included in the matched groups. Baseline patient characteristics including comorbidities, vital signs, and bleeding scores were similar in the matched groups. The rate of immediate hemostasis and 7-day and 30-day rebleeding were also similar in the two groups before and after matching. In the subgroup analysis, no significant differences in immediate hemostasis or rebleeding rate were noted between PHP in monotherapy and PHP combined with a conventional hemostatic method. At 30 days after the therapy, there were no significant PHP-related complications or mortality. Given its safety, the PHP proved feasible for endoscopic treatment of UGIB, having similar effectiveness as that of conventional therapy. The PHP may become a promising hemostatic method for non-variceal UGIB. © 2018 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

    Haemorrhagic diathesis has been of much concern to health professionals including dentists. It is not infrequent that a dentist becomes the first person to diagnose a bleeding disorder while performing dental treatment. Haemophilia is an X linked disorder with a frequency of about 1:10 000 births. Haemophilia B is much less common than haemophilia A, and affects only 1:300 000 males born alive. The clinical features of haemophilia B are very similar to those of haemophilia A with a prolongation of activated partial thromboplastin time. This case report describes the dental management of a patient with an uncommon haematological disorder, namely, factor IX deficiency, which remained undiagnosed until the patient had to undergo dentofacial trauma with unexpected severe haemorrhage. Preventive dentistry remains vital to young haemophiliacs. Surgical dental procedures may be performed for haemophiliacs but they must be judiciously coordinated by dental and medical health professionals. PMID:25568261

    Crimean Congo haemorrhagic fever (CCHF) is a tick-borne disease that occurs in parts of Asia, Europe and Africa. Since 2000 the infection has caused epidemics in Turkey, Iran, Russia, Uganda and Pakistan. Good-quality general supportive medical care helps reduce mortality. There is uncertainty and controversy about treating CCHF with the antiviral drug ribavirin. To assess the effects of ribavirin for treating people with Crimean Congo haemorrhagic fever. We searched the Cochrane Infectious Diseases Group Specialized Register; the Central Register of Controlled Trials (CENTRAL); MEDLINE (PubMed); Embase (OVID); Science Citation Index-Expanded, Social Sciences Citation index, conference proceedings (Web of Science); and CINAHL (EBSCOHost). We also searched the WHO International Clinical Trials Registry Platform (ICTRP) and ClinicalTrials.gov for trials in progress. We conducted all searches up to 16 October 2017. We also contacted experts in the field and obtained further studies from these sources. We evaluated studies assessing the use of ribavirin in people with suspected or confirmed Crimean Congo haemorrhagic fever. We included randomised control trials (RCTs); non-randomised studies (NRSs) that included more than 10 participants designed as cohort studies with comparators; and case-control studies. Two review authors assessed eligibility, risk of bias, and extracted data. For non-randomized studies we used the ROBINS-I tool to assess risk of bias. The main effects analysis included all studies where we judged the risk of bias to be low, moderate or high. We summarized dichotomous outcomes using risk ratios (RRs) and continuous outcomes using mean differences (MDs), and used meta-analyses where appropriate. We carried out a subsidiary appraisal and analysis of studies with critical risk of bias for the primary outcome, as these are often cited to support using ribavirin. For the main effects analysis, five studies met our inclusion criteria: one RCT with 136

    We reviewed the haemorrhagic complications of the endovascular treatment of intracranial aneurysms, in terms of frequency, pre-embolisation clinical status, clinical and radiological manifestations, management and prognosis. In 275 patients treated for 303 aneurysms over 7 years we had seven (one man and six women--2.3%) with haemorrhage during or immediately after endovascular treatment. All procedures were performed with a standardised protocol of heparinisation and anaesthesia. Four had ruptured aneurysms, two at the tip of the basilar artery, and one ach on the internal carotid and posterior cerebral artery, treated after 12, 5, 14, and 2 days, respectively, three were in Hunt and Hess grade 2 and one in grade 1. Bleeding occurred during coiling in three, after placement of at least four coils, and during manipulation of the guidewire to enter the aneurysm in the fourth. Haemorrhage was manifest as extravasation of contrast medium, with a sudden rise in systolic blood pressure in three patients. The other three patients had unruptured aneurysms; they had stable blood pressure and angiographic findings during the procedure, but one, under sedation, had seizures immediately after insertion of four coils, and the other two had seizures, headache and vomiting on the day following the procedure. Heparin reversal with protamine sulphate was started promptly started when bleeding was detected in four patients, and the embolisation was completed with additional coils in three. Emergency ventricular drainage was performed in the two patients with ruptured aneurysm and one with an unruptured aneurysm who had abnormal neurological responses or hydrocephalus. The bleeding caused a third nerve palsy in one patient, which might have been due to ischaemia and progressively improved.

    Oral anticoagulation therapy is recommended for the prevention of recurrent ischemic stroke in patients with atrial fibrillation (AF). Current guidelines do not provide evidence-based recommendations on optimal time-point to start anticoagulation therapy after an acute ischemic stroke. Non-vitamin K antagonist oral anticoagulants (NOACs) may offer advantages compared to warfarin because of faster and more predictable onset of action and potentially a lower risk of intracerebral haemorrhage also in the acute phase after an ischemic stroke. The TIMING study aims to establish the efficacy and safety of early vs delayed initiation of NOACs in patients with acute ischemic stroke and AF. The TIMING study is a national, investigator-led, registry-based, multicentre, open-label, randomised controlled study. The Swedish Stroke Register is used for enrolment, randomisation and follow-up of 3000 patients, who are randomised (1:1) within 72 h from ischemic stroke onset to either early (≤ 4 days) or delayed (≥ 5-10 days) start of NOAC therapy. The primary outcome is the composite of recurrent ischemic stroke, symptomatic intracerebral haemorrhage, or all-cause mortality within 90 days after randomisation. Secondary outcomes include: individual components of the primary outcome at 90 and 365 days; major haemorrhagic events; functional outcome by the modified Rankin Scale at 90 days; and health economics. In an optional biomarker sub-study, blood samples will be collected after randomisation from approximately half of the patients for central analysis of cardiovascular biomarkers after study completion. The study is funded by the Swedish Medical Research Council. Enrolment of patients started in April 2017. The TIMING study addresses the ongoing clinical dilemma of when to start NOAC after an acute ischemic stroke in patients with AF.

    Stroke risk is modifiable through many risk factors, one being healthy dietary habits. Fibre intake was associated with a reduced stroke risk in recent meta-analyses; however, data were contributed by relatively few studies, and few examined different stroke types. A total of 27,373 disease-free women were followed up for 14.4 years. Diet was assessed with a 217-item food frequency questionnaire and stroke cases were identified using English Hospital Episode Statistics and mortality records. Survival analysis was applied to assess the risk of total, ischaemic or haemorrhagic stroke in relation to fibre intake. A total of 135 haemorrhagic and 184 ischaemic stroke cases were identified in addition to 138 cases where the stroke type was unknown or not recorded. Greater intake of total fibre, higher fibre density and greater soluble fibre, insoluble fibre and fibre from cereals were associated with a significantly lower risk for total stroke. For total stroke, the hazard ratio per 6 g/day total fibre intake was 0.89 (95% confidence intervals: 0.81-0.99). Different findings were observed for haemorrhagic and ischaemic stroke in healthy-weight or overweight women. Total fibre, insoluble fibre and cereal fibre were inversely associated with haemorrhagic stroke risk in overweight/obese participants, and in healthy-weight women greater cereal fibre was associated with a lower ischaemic stroke risk. In non-hypertensive women, higher fibre density was associated with lower ischaemic stroke risk. Greater total fibre and fibre from cereals are associated with a lower stroke risk, and associations were more consistent with ischaemic stroke. The different observations by stroke type, body mass index group or hypertensive status indicates potentially different mechanisms.

    Pathogenesis of viral haemorrhagic fever (VHF) is closely associated with alterations of the vascular system. Among the virus families causing VHF, filoviruses (Marburg and Ebola) are the most fatal, and will be focused on here. After entering the body, Ebola primarily targets monocytes/macrophages and dendritic cells. Infected dendritic cells are largely impaired in their activation potency, likely contributing to the immune suppression that occurs during filovirus infection. Monocytes/macrophages, however, immediately activate after viral contact and release reasonable amounts of cytokines that target the vascular system, particularly the endothelial cells. Some underlying molecular mechanisms such as alteration of the vascular endothelial cadherin/catenin complex, tyrosine phosphorylation, expression of cell adhesion molecules, tissue factor and the effect of soluble viral proteins released from infected cells to the blood stream will be discussed.

    One hundred consecutive patients treated with epsilon aminocaproic acid 24 grams daily prior to surgery for ruptured intracranial aneurysms have been compared with the previous 100 patients managed similarly but without anti-fibrinolytic drugs. No other alterations in management were made and the two series are closely comparable in all other respects. Fewer episodes of recurrent haemorrhage and deaths from this cause occurred in the treated patients, but more cases of cerebral ischaemia occurred. Neither difference is statistically significant and overall more deaths occurred in the patients treated with antifibrinolytic drugs. The value of this method of treatment in the management of aneurysmal subarachnoid haemorrhage is questioned. PMID:7229645

    A 39-year-old Zimbabwean man presented with a 1 week history of fever, general malaise and acute-onset chest pain. He had a urethral stricture, which had been managed with an indwelling supra-pubic catheter. The electrocardiography on admission showed inferior ST-T segments elevation. His chest pain and electrocardiography changes resolved subsequent to thrombolysis, and he remained haemodynamically stable. The 12-h troponin I was increased at 10.5 microg/l (NR <0.04 microg/l). Echocardiography confirmed severe mitral regurgitation and a flail anterior mitral valve leaflet with an independently oscillating mobile vegetation. Enterococci faecalis were grown on blood cultures. A diagnosis of enterococci infective endocarditis with concomitant acute myocardial infarction due to possible septic emboli was made. Despite the successful outcome from thrombolysis in the setting of acute myocardial infarction with infective endocarditis, the case highlights the current lack of definitive data on the optimal acute management of such an unusual clinical scenario. Although there is serious concern that thrombolytic treatment for myocardial infarction in the setting of infective endocarditis may be associated with higher risk of cerebral haemorrhage, there is little documented evidence supporting the safety of primary percutaneous coronary intervention with these patients.

    Despite the increasing and broadening use of agents targeting the vascular endothelial growth factor (VEGF) pathway, little is known on their acute neurovascular toxicities. This retrospective, multi-centre study examined the characteristics of patients with solid tumours who experienced an ischaemic or haemorrhagic stroke, a transient ischaemic accident (TIA) or a posterior reversible encephalopathy syndrome (PRES) while under anti-VEGF and until 8 weeks after termination of treatment and evaluated their management in our institutions from 2004 to 2014. Patients with newly diagnosed or progressive cerebral metastases at the time of the acute neurovascular event were excluded. Thirty-four patients (55.9% men) were identified, and experienced either ischaemic stroke (n = 18), PRES (n = 9), TIA (n = 6) or haemorrhagic stroke (n = 1). At initiation of anti-VEGF agents, 64.7% of patients had previous cardiovascular risk factors, and 52.9% had hypertension. Eight patients (23.5%) had received cerebral radiotherapy, five of which concomitantly to anti-VEGF treatment. Six (17%) patients died in the 8 weeks following the acute neurovascular event, and only 55.9% recovered their initial neurological status. Overall, 1-year and 2-year survival rates after the acute neurovascular event were 67.9% and 50%, respectively. When anti-VEGF agents were reintroduced (n = 6), severe vascular toxicity recurred in two patients. Neurovascular events under VEGF treatments are potentially severe, and the management of comorbid conditions has to be improved. A prospective collection of data and standardised management of such events is therefore being structured in our institutions. Copyright © 2016 Elsevier Ltd. All rights reserved.

To assess the contribution of brain imaging to the diagnosis and management of stroke, and to estimate the costs, benefits and risks of different imaging strategies in order to provide data to inform national and local policy on the use of brain imaging in stroke.

The effect on functional outcome after ischaemic or haemorrhagic stroke, tumours or infections, of correctly administered antithrombotic or other treatment; of time to scan and stroke severity on diagnosis by CT or MRI; on management, including length of stay, functional outcome, and quality-adjusted life years (QALYs), of the diagnostic information provided by CT scanning; the cost-effectiveness (cost versus QALYs) of different strategies for use of CT after acute stroke. Death and functional outcome at long-term follow-up; accuracy of CT and MRI; cost of CT scanning by time of day and week; effect of CT diagnosis on change in health outcome, length of stay in hospital and QALYs; cost-effectiveness of various scanning strategies. CT is very sensitive and specific for haemorrhage within the first 8 days of stroke only. Suboptimal scanning used in epidemiology studies suggests that the frequency of primary intracerebral haemorrhage (PICH) has been underestimated. Aspirin increases the risk of PICH. There were no reliable data on functional outcome or on the effect of antithrombotic treatment given long term after PICH. In 60% of patients with recurrent stroke after PICH, the cause is another PICH and mortality is high among PICH patients. A specific MR sequence (gradient echo) is required to

    Cerebral amyloid angiopathy (CAA) is a common aetiology of convexal subarachnoid haemorrhage (cSAH) but little is known about its specific characteristics in comparison with cSAH from other causes. In this study we compared patients with CAA vs. non-CAA-related cSAH. Retrospective review of baseline and follow-up data of consecutive patients admitted with a symptomatic acute cSAH. Sixty-two patients were included (mean age 66.2 ± 14.1 years), of whom 31 with probable CAA. CAA patients presented more frequently with transient symptoms (83.9 vs. 19.3%; p < 0.001) usually without headache (19.0 vs. 58.1%; p = 0.002). In CAA, these were essentially positive sensory disturbance that met the criteria of transient focal neurological episodes (TFNE). CAA was more often associated with cortical superficial siderosis (cSS) (80.6 vs. 0%; p < 0.001) and lobar cerebral microbleeds (83.4 vs. 9%; p < 0.001). During a mean of 22 months of follow-up, recurrent symptomatic cSAH occurred in 4/27 (12.9%) CAA patients and in 0/27 non-CAA patients. Among 40 patients with MRI follow-up, cSAH recurrences were observed in 44% of CAA patients vs. 13.3% of other cases (p = 0.08) and extension of cSS was detected only in CAA (60%) (p < 0.001). Acute cSAH evolved to cSS in 96 and 73.3% of CAA and non-CAA patients, respectively (p = 0.06). CAA differs from other cSAH in having TFNE as a frequent clinical presentation, a high prevalence of cSS and an increased risk of recurrent subarachnoid bleeding. However, evolution from acute cSAH to focal cSS may not be specific to CAA.

    Background Treatments for major internal bleeding after injury include permissive hypotension to decrease the rate of blood loss, intravenous infusion of plasma or clotting factors to improve clot formation, and rapid surgical haemostasis or arterial embolization to control bleeding vessels. Yet, little is known regarding major internal arterial haemostasis, or how these commonly-used treatments might influence haemostasis. Objectives (1) Use a swine model of femoral artery bleeding to understand the perivascular haemostatic response to contained arterial haemorrhage. (2) Directly confirm the association between hemodynamics and bleeding velocity. (3) Observe the feasibility of delivering an activated clotting factor directly to internal sites of bleeding using a simplified angiographic approach. Methods Ultrasound was used to measure bleeding velocity and in vivo clot formation by elastography in a swine model of contained femoral artery bleeding with fluid resuscitation. A swine model of internal pelvic and axillary artery haemorrhage was also used to demonstrate feasibility of local delivery of an activated clotting factor. Results In this model, clots formed slowly within the peri-wound hematoma , but eventually containing the bleeding. Central hemodynamics correlated positively with bleeding velocity. Infusion of recombinant human activated Factor VII into the injured artery nearby the site of major internal haemorrhage in the pelvis and axillae was feasible. Conclusions We rediscover that clot formation within the peri-wound haematoma is an integral component of haemostasis and a feasible target for treatment of major internal bleeding using activated clotting factors delivered using a simplified angiographic approach.

    2008-08-01

    The National Institute for Health and Clinical Excellence (NICE) issued guidance on surgical techniques for tonsillectomy during a national audit of surgical practice and postoperative complications. To assess the impact of the guidance on tonsillectomy practice and outcomes. An interrupted time-series analysis of routinely collected Hospital Episodes Statistics data, and an analysis of longitudinal trends in surgical technique using data from the National Prospective Tonsillectomy Audit. Patients undergoing tonsillectomy in English NHS hospitals between January 2002 and December 2004. Postoperative haemorrhage within 28 days. The rate of haemorrhage increased by 0.5% per year from 2002, reaching 6.4% when the guidance was published. After publication, the rate of haemorrhage fell immediately to 5.7% (difference 0.7%: 95% CI -1.3% to 0.0%) and the rate of increase appeared to have stopped. Data from the National Prospective Tonsillectomy Audit showed that the fall coincided with a shift in surgical techniques, which was consistent with the guidance. NICE guidance influenced surgical tonsillectomy technique and in turn produced an immediate fall in postoperative haemorrhage. The ongoing national audit and strong support from the surgical specialist association may have aided its implementation.

    To determine the safety and efficiency of an acute stroke thrombolysis service in a New Zealand public hospital setting. A 12-month audit of patients referred to the Christchurch Hospital Stroke Thrombolysis Service (STS) between 1 April 2002 and 31 March 2003 was undertaken. Sixty-one patients were referred to the STS during the study period, of whom 16 were treated with tissue plasminogen activator (t-PA). For treated patients, the median time from stroke onset to hospital presentation was 60 minutes, 'door-to-CT' time was 60 minutes, and the 'door-to-needle' time was 99 minutes. Minor protocol violations were recorded in two patients, but did not influence outcome. No patient was treated after 3 hours of stroke onset. Intracerebral haemorrhage occurred in two patients: one patient was significantly improved compared with pre-treatment status; a minor temporary deterioration occurred in the other patient. Eight of 16 patients had improved by 4 or more points on the NIH Stroke Scale Score at 24 hours. Acute stroke thrombolysis can be delivered safely and in accordance with internationally accepted guidelines using the Christchurch Hospital STS model of emergency department screening and acute stroke service treatment. Further improvements in performance of the STS remain possible.

    2012-12-01

    Terminal haemorrhage is a rare and distressing emergency in palliative oncology. We present an algorithm for the management of terminal haemorrhage in patients likely to receive end-of-life care at home, based on a literature review of the management of terminal haemorrhage for patients with advanced cancer, where a DNAR (do not attempt resuscitation) order is in place and the patient wishes to die at home. A literature review was conducted to identify literature on the management of terminal haemorrhage in patients with advanced cancer who are no longer amenable to active interventional/invasive procedures. Electronic databases, the grey literature, local guidelines from hospitals and hospices, and online web portals were all searched systematically. The literature review was used to formulate a management algorithm. The evidence base is very limited. A three-step practical algorithm is suggested: preparing for the event, managing the event ('ABC') and 'aftercare'. Step 1 involves the identification and optimisation of risk factors. Step 2 (the event) consists of A (assure and re-assure the patient), B (be there - above all stay with the patient) and C (comfort, calm, consider dark towels and anxiolytics if possible). Step 3 (the aftercare) involves the provision of practical and psychological support to those involved including relatives and professionals. Terminal haemorrhage is a rare yet highly feared complication of advanced cancer, for which there is a limited evidence base to guide management. The suggested three-step approach to managing this situation gives professionals a logical framework within which to work.

    1983-01-01

    Five patients given vasopressin by infusion to reduce portal hypertension developed signs of cutaneous gangrene 18-24 hours after the start of the infusion. Four patients were treated by application of local dressings; in three cases the lesions healed, but the fourth patient died from variceal haemorrhage. The remaining patient required split skin grafting but died 48 hours after operation. The mechanism of this effect of vasopressin is not clear, but if local blanching of the skin is noted during infusion the catheter should be flushed immediately with a vasodilator in an effort to counteract the drug's vasoconstrictor effect.

    Viral haemorrhagic fevers (VHFs) are severe infections capable of causing haemorrhagic disease and fatal multi-organ failure. Crimean-Congo, Marburg, Ebola and Lassa viruses cause both sporadic cases and large epidemics over wide endemic areas. Original articles and reviews identified by PubMed search and personal reading; European and United States national guidance and legislation. World Health Organization information, documents and reports. VHFs cause significant morbidity and mortality in their endemic areas; they can cause healthcare-related infections, and their broad diversity and range are increasingly recognized. There is uncertainty about the risks presented by VHFs in non-endemic countries, particularly in healthcare environments. Consensus on the best modes of care and infection control are only slowly emerging. With increasing commerce in rural and low-income areas, VHF outbreaks increasingly expand, causing social and economic damage. New ecologies, viral strains and clinical syndromes are being discovered. There is a great need for rapid diagnostic tests and effective antiviral treatments. Vaccine development programmes are challenged by multiple viral strains and the need for trials in rural communities.

    Intraventricular haemorrhage is a subtype of intracerebral haemorrhage, with 50% mortality and serious disability for survivors. We aimed to test whether attempting to remove intraventricular haemorrhage with alteplase versus saline irrigation improved functional outcome. In this randomised, double-blinded, placebo-controlled, multiregional trial (CLEAR III), participants with a routinely placed extraventricular drain, in the intensive care unit with stable, non-traumatic intracerebral haemorrhage volume less than 30 mL, intraventricular haemorrhage obstructing the 3rd or 4th ventricles, and no underlying pathology were adaptively randomly assigned (1:1), via a web-based system to receive up to 12 doses, 8 h apart of 1 mg of alteplase or 0·9% saline via the extraventricular drain. The treating physician, clinical research staff, and participants were masked to treatment assignment. CT scans were obtained every 24 h throughout dosing. The primary efficacy outcome was good functional outcome, defined as a modified Rankin Scale score (mRS) of 3 or less at 180 days per central adjudication by blinded evaluators. This study is registered with ClinicalTrials.gov, NCT00784134. Between Sept 18, 2009, and Jan 13, 2015, 500 patients were randomised: 249 to the alteplase group and 251 to the saline group. 180-day follow-up data were available for analysis from 246 of 249 participants in the alteplase group and 245 of 251 participants in the placebo group.

    Summary Background Many international guidelines on the prevention of venous thromboembolism recommend targeting heparin treatment at patients with stroke who have a high risk of venous thrombotic events or a low risk of haemorrhagic events. We sought to identify reliable methods to target anticoagulant treatment and so improve the chance of avoiding death or dependence after stroke. Methods We obtained individual patient data from the five largest randomised controlled trials in acute ischaemic stroke that compared heparins (unfractionated heparin, heparinoids, or low-molecular-weight heparin) with aspirin or placebo. We developed and evaluated statistical models for the prediction of thrombotic events (myocardial infarction, stroke, deep vein thrombosis, or pulmonary embolism) and haemorrhagic events (symptomatic intracranial or significant extracranial) in the first 14 days after stroke. We calculated the absolute risk difference for the outcome “dead or dependent” in patients grouped by quartiles of predicted risk of thrombotic and haemorrhagic events with random effect meta-analysis. Findings Patients with ischaemic stroke who were of advanced age, had increased neurological impairment, or had atrial fibrillation had a high risk of both thrombotic and haemorrhagic events after stroke. Additionally, patients with CT-visible evidence of recent cerebral ischaemia were at increased risk of thrombotic events. In evaluation datasets, the area under a receiver operating curve for prediction models for thrombotic events was 0·63 (95% CI 0·59–0·67) and for haemorrhagic events was 0·60 (0·55–0·64). We found no evidence that the net benefit from heparins increased with either increasing risk of thrombotic events or decreasing risk of haemorrhagic events. Interpretation There was no evidence that patients with ischaemic stroke who were at higher risk of thrombotic events or lower risk of haemorrhagic events benefited from heparins.

    Background Emergency stent placement in the extracranial internal carotid artery in combination with anterior circulation thrombectomy is a routine procedure. Yet, precise indications and clinical safety in this setting remains controversial. Present data for mechanical thrombectomy include few studies with acute stenting of tandem occlusions. We evaluated the feasibility, safety and clinical outcome of this endovascular treatment in a retrospective analysis of all consecutive cases at a comprehensive stroke centre. Methods This was a retrospective analysis of all consecutive patients with acute extracranial carotid artery occlusion including acute dissection or high-grade stenosis and concomitant intracranial large-vessel occlusion treated with emergency carotid stenting and intracranial mechanical thrombectomy between November 2007 and May 2015. Results A total of 63 patients with a median age of 67 years (range 33-84 years) were treated. Of these, 33 (52%) patients had concomitant intravenous thrombolysis with recombinant tissue-type plasminogen activator initially. Median admission National Institutes of Health Stroke Scale was 14 (range 1-29). Median time from stroke onset to recanalization was 408 minutes (range 165-1846 minutes). Procedure time was significantly shorter after intravenous thrombolysis (110 minutes [range 15-202 minutes] vs. 130 minutes [range 60-280 minutes]; p = 0.02). Three (5%) patients experienced post-procedural symptomatic intracerebral haemorrhage. In 55/63 (87%) patients, a score of ≥2b on the Thrombolysis in Cerebral Infarction scale could be achieved. Eight (13%) patients died, five (8%) during the acute phase. A total of 29/63 (46%) patients showed a favourable outcome (modified Rankin Scale score of 0-2) after three months. Conclusions Our single-centre retrospective analysis of emergency stent placement in the extracranial internal carotid artery in combination with anterior circulation thrombectomy demonstrated high

    INTRODUCTION Intractable haemorrhage after endoscopic surgery, including transurethral resection of the prostate (TURP) and photoselective vaporisation of the prostate (PVP), is uncommon but a significant and life-threatening problem. The knowledge and technical experience to deal with this complication may not be wide-spread among urologists and trainees. We describe our series of TURPs and PVPs and the incidence of postoperative bleeding requiring intervention. PATIENTS AND METHODS We retrospectively reviewed 437 TURPs and 590 PVPs over 3 years in our institution. We describe the conservative, endoscopic and open prostatic packing techniques used for patients who experienced postoperative bleeding. RESULTS Of 437 TURPs, 19 required endoscopic intervention for postoperative bleeding. Of 590 PVPs, two patients were successfully managed endoscopically for delayed haemorrhage at 7 and 13 days post-surgery, respectively. In one TURP and one PVP patient, endoscopic management was insufficient to control postoperative haemorrhage and open exploration and packing of the prostatic cavity was performed. CONCLUSIONS Significant bleeding after endoscopic prostatic surgery is still a potentially life-threatening complication. Prophylactic measures have been employed to reduce peri-operative bleeding but persistent bleeding post-endoscopic prostatic surgery should be treated promptly to prevent the risk of rapid deterioration. We demonstrated that the technique of open prostate packing may be life-saving. PMID:20522311

    To implement a policy of systematic screening for viral haemorrhagic fever (VHF) among travellers returning from African countries with fever, commencing at initial clinical contact. A protocol based on UK Advisory Committee on Dangerous Pathogens guidance was developed collaboratively by medical, nursing and laboratory staff. Audit was carried out to quantify resource demands and effects on time to diagnose malaria, the main differential diagnosis. A protocol is now implemented for all patients presenting to HTD with fever, with clear guidelines for interaction with clinical and laboratory staff at each stage. The protocol required moderate amounts of clinical and laboratory staff time and resulted in some additional hospital admissions. The time to a diagnosis of malaria increased from a median of 90 (range 50-125) min in patients without VHF risk to a median of 140 (range 101-225) min (p=0.0025) in those assessed as at risk. Although all acute medical services need to have robust procedures for early detection of patients with serious transmissible conditions, few implement such a policy. Our protocol requires increased human and other resources but has no important impact on the rapidity of diagnosis of malaria, and is now embedded in local practice.

    Bleeding from esophageal varices is a life threatening complication of portal hypertension. Primary prevention of bleeding in patients at risk for a first bleeding episode is therefore a major goal. Medical prophylaxis consists of non-selective beta-blockers like propranolol or carvedilol. Variceal endoscopic band ligation is equally effective but procedure related morbidity is a drawback of the method. Therapy of acute bleeding is based on three strategies: vasopressor drugs like terlipressin, antibiotics and endoscopic therapy. In refractory bleeding, self-expandable stents offer an option for bridging to definite treatments like transjugular intrahepatic portosystemic shunt (TIPS). Treatment of bleeding from gastric varices depends on vasopressor drugs and on injection of varices with cyanoacrylate. Strategies for primary or secondary prevention are based on non-selective beta-blockers but data from large clinical trials is lacking. Therapy of refractory bleeding relies on shunt-procedures like TIPS. Bleeding from ectopic varices, portal hypertensive gastropathy and gastric antral vascular ectasia-syndrome is less common. Possible medical and endoscopic treatment options are discussed. PMID:23964137

    Parry–Romberg syndrome (PRS) or progressive hemi facial atrophy syndrome is a rare condition of unknown aetiology that is characterised by progressive unilateral facial and cranial atrophic changes of skin, subcutaneous tissues and bone. The authors describe a 37-year-old female with a history of PRS, who presented with a subarachnoid haemorrhage secondary to rupture of a 9 mm fusiform aneurysm of the posterior cerebral artery. There was an associated external carotid arterio-venous fistula noted with this aneurysm. The aneurysm was treated by endovascular route and was successfully coiled. Follow-up angiogram revealed spontaneous resolution of the fistula with good occlusion of the aneurysm. The aetio-pathogenesis of this rare occurrence, literature review and its management is discussed. PMID:22674607

    Dengue viral infections are one of the most important mosquito borne diseases in the world. The dengue virus is a single stranded RNA virus belonging to the Flaviviridae family. There are four serotypes (DEN 1–4) classified according to biological and immunological criteria. Patients may be asymptomatic or their condition may give rise to undifferentiated fever, dengue fever, dengue haemorrhagic fever (DHF), or dengue shock syndrome. Annually, 100 million cases of dengue fever and half a million cases of DHF occur worldwide and 2.5 billion people are at risk. At present, dengue is endemic in 112 countries. Early recognition and prompt initiation of appropriate treatment are vital if disease related morbidity and mortality are to be limited. We present an interesting case of dengue fever with headache, skin rash and abnormal behaviour who had a massive intracranial haemorrhage with fatal outcome. PMID:22242067

He returned with primary post-tonsillectomy haemorrhage 18 h after the operation and required bipolar cautery to the multiple small bleeding points in the right and left tonsillar fossa. Thorough coagulation screen was normal. Recurrent primary haemorrhage occurred 3 h post-operatively requiring immediate surgical intervention, removal of the inferior poles, precautionary throat packs, intubation and observation on the intensive treatment unit (ITU). Re-examination in theatre revealed a bleeding left superior pole that was under-run to achieve haemostasis and the patient returned to ITU. Hypertensive episodes were noted in the emergency department and intraoperatively including one recording >200 mm Hg. Haemostasis was eventually achieved once the blood pressure was adequately controlled. A slow wean of steroids was also instigated and the patient was managed on a surgical ward for 2 weeks post-tonsillectomy. PMID:25398921

    Objectives To elucidate the association between antiplatelet use in patients with non-haemorrhagic moyamoya disease before hospital admission and good functional status on admission in Japan. Design Retrospective, multicentre, non-randomised, observational study. Setting Nationwide registry data in Japan. Participants A total of 1925 patients with non-haemorrhagic moyamoya disease admitted between 1 April 2012 and 31 March 2014 in Japan. Main outcome measure We performed propensity score-matched analysis to examine the association between prehospital antiplatelet use and no significant disability on hospital admission, as defined by a modified Rankin Scale score of 0 or 1. Results Propensity-matched patients who received prehospital antiplatelet drugs were associated with a good outcome on hospital admission (OR adjusted for all covariates, 3.82; 95% CI 1.22 to 11.99) compared with those who did not receive antiplatelet drugs prior to hospital admission. Conclusions Prehospital antiplatelet use was significantly associated with good functional status on hospital admission among patients with non-haemorrhagic moyamoya disease in Japan. Our results suggest that prehospital antiplatelet use should be considered when evaluating outcomes of patients with non-haemorrhagic moyamoya disease. PMID:27008684

    The Crimean-Congo haemorrhagic fever virus (CCHFV), which is transmitted by the ticks of Hyalomma spp. in general and H. marginatumin particular, can cause severe disease in humans, with mortality rates of 3-30%. Other than from the bites of infected ticks, CCHFV can also be transmitted through contact with patients with the acute phase of infection or contact with blood or tissues from viraemic livestock.  Outbreaks of human cases of haemorrhagic manifestations have been documented since 1945 and described in parts of Africa, Asia, Eastern Europe and the Middle East and most recently India in 2011. In addition, serological evidence of the disease has been reported in some countries where no human cases were reported. As regional neighbours China and India have been affected by this virus, this study was conducted to determine the seroprevalence of CCHFV among Orang Asli population of Malaysia as the most at risk people who residing in the deep forests. A total of 682 serum samples were collected from the Orang Asli population residing in eight states in peninsular Malaysia and analysed for the presence of anti-CCHFV immunoglobulin G (IgG) using a commercial enzyme-linked immunosorbent assay kit. The study subjects comprised 277 (40.6%) men and 405 (59.4%) women. However, anti-CCHFV IgG was detected in only one female serum sample (0.1%). The presence of anti-CCHFV IgG could not be correlated to age or sex from these findings. The results of this screening survey showed that the seroprevalence of the anti-CCHFV IgG among Malaysia's Orang Asli population is too low for detection or totally negative compared with that in neighbouring countries, such as India and China.

    Severe haemorrhage is a leading cause of maternal death worldwide. Most haemorrhage deaths occur soon after childbirth. Severe post-partum bleeding is sometimes managed by the surgical removal of the uterus (hysterectomy). Death and hysterectomy are important health consequences of post-partum haemorrhage, and clinical trials of interventions aimed at preventing these outcomes are needed. The World Maternal Antifibrinolytic trial aims to determine the effect of tranexamic acid on death, hysterectomy and other health outcomes in women with post-partum haemorrhage. It is an international, multicentre, randomised trial. Approximately 20,000 women with post-partum haemorrhage will be randomly allocated to receive an intravenous injection of either tranexamic acid or matching placebo in addition to usual care. The primary outcome measure is a composite of death in hospital or hysterectomy within 42 days of delivery. The cause of death will be described. Secondary outcomes include death, death due to bleeding, hysterectomy, thromboembolic events, blood transfusion, surgical and radiological interventions, complications, adverse events and quality of life. The health status and occurrence of thromboembolic events in breastfed babies will also be reported. We will conduct subgroup analyses for the primary outcome by time to treatment, type of delivery and cause of haemorrhage. We will conduct an analysis of treatment effect adjusted for baseline risk. The World Maternal Antifibrinolytic trial should provide reliable evidence for the efficacy of tranexamic acid in the prevention of death, hysterectomy and other outcomes that are important to patients. We present a protocol update and the statistical analysis plan for the trial.

    Liver cirrhosis is a serious disease shortening the life expectancy. Unavoidable consequence of cirrhosis is portal hypertension, which usually limits the prognosis by its complications. Portal hypertension is a prognostic factor for cirrhosis decompensation, variceal bleeding and even the mortality in cirrhotic patients. In the evaluation of portal hypertension hepatic venous pressure gradient (HVPG) measurement is used.Measurement of HVPG is used in clinical praxis in these situations: diagnosis of portal hypertension, evaluation of prognosis of patients with cirrhosis, monitoring the treatment efficacy in the prevention of variceal bleeding, management of acute variceal bleeding. Decrease of HVPG below 12 mmHg or at least for more than 20% of initial value in the treatment by beta-blockers is associated with the lower risk of bleeding from varices or other complications. HVPG above 20 mm Hg is associated with the high risk of early rebleeding from varices and can discriminate those patients profiting from early TIPS.HVPG measurement is an invasive, but simple, reproducible and safe catheterization technique with minimal complication rate. The most frequent complication could be incorrect assessment of obtained values. HVPG measurement should be a routine technique in centers specialized to liver diseases.

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 significance of congenital abnormalities in predisposing to portal hypertension and variceal haemorrhage needs to be remembered when these effects manifest in childhood, as portal venography will permit elucidation of the complicated congenital developmental abnormalities underlying the pathological condition and permit rational surgical amelioration. In the presence of portal hypertension the development of a collateral venous circulation may be represented by a hepatopetal or hepatofugal circulatory pattern and will closely parallel the developmental areas where portal and systemic venous circulations meet, being representative of the embryological anastomosis between the vitelloumbilical system and the posterior cardinal system of veins.

    The emergence of bluetongue disease (BT) among livestock in Europe in 2006 raised many questions including the occurrence and epidemiological significance of foetal infections in cattle. To clarify these aspects, vaccinated and unvaccinated pregnant heifers were sequentially infected twice in an isolation facility (biosafety level 3) with a northern European outbreak strain of Bluetongue virus serotype 8 (BTV-8). The study was terminated 2 months after calving with necropsy of the dams and their offspring. The cattle were monitored throughout the study by clinical scoring and for the presence of circulating neutralising antibodies, and after calving for the presence of infectious virus and viral RNA in blood and milk. Four calves, one born from a vaccinated dam and three from non-vaccinated ones, that were infected at 120 days of gestation had obvious haemorrhage of the pulmonary artery at necropsy. Although haemorrhage of the pulmonary artery is highly characteristic of BT, viral RNA was not detected in any of these calves. Furthermore, although none of the calves born from heifers infected prior to mid-gestation had teratogenic BTV typical brain lesions, some had lesions at birth suggestive of in utero BTV infection. Despite the lack of viral RNA detection, the presence of haemorrhage of the pulmonary artery deserves to be reported as a new observation in the context of the multiple investigations having as main subject the BTV placental crossing in cattle.

    Objective To conduct a systematic review of studies reporting on the validity of International Classification of Diseases (ICD) codes for identifying stroke in administrative data. Methods MEDLINE and EMBASE were searched (inception to February 2015) for studies: (a) Using administrative data to identify stroke; or (b) Evaluating the validity of stroke codes in administrative data; and (c) Reporting validation statistics (sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), or Kappa scores) for stroke, or data sufficient for their calculation. Additional articles were located by hand search (up to February 2015) of original papers. Studies solely evaluating codes for transient ischaemic attack were excluded. Data were extracted by two independent reviewers; article quality was assessed using the Quality Assessment of Diagnostic Accuracy Studies tool. Results Seventy-seven studies published from 1976–2015 were included. The sensitivity of ICD-9 430-438/ICD-10 I60-I69 for any cerebrovascular disease was ≥ 82% in most [≥ 50%] studies, and specificity and NPV were both ≥ 95%. The PPV of these codes for any cerebrovascular disease was ≥ 81% in most studies, while the PPV specifically for acute stroke was ≤ 68%. In at least 50% of studies, PPVs were ≥ 93% for subarachnoid haemorrhage (ICD-9 430/ICD-10 I60), 89% for intracerebral haemorrhage (ICD-9 431/ICD-10 I61), and 82% for ischaemic stroke (ICD-9 434/ICD-10 I63 or ICD-9 434&436). For in-hospital deaths, sensitivity was 55%. For cerebrovascular disease or acute stroke as a cause-of-death on death certificates, sensitivity was ≤ 71% in most studies while PPV was ≥ 87%. Conclusions While most cases of prevalent cerebrovascular disease can be detected using 430-438/I60-I69 collectively, acute stroke must be defined using more specific codes. Most in-hospital deaths and death certificates with stroke as a cause-of-death correspond to true stroke deaths. Linking vital

    In high- and low-performing districts of Bangladesh, the study explored the demand-side of maternal healthcare by looking at differences in perceived knowledge and care-seeking behaviours of women in relation to postpartum haemorrhage or eclampsia. Haemorrhage and eclampsia are two major causes of maternal mortality in Bangladesh. The study was conducted during July 2006-December 2007. Both postpartum bleeding and eclampsia were recognized by women of different age-groups as severe and life-threatening obstetric complications. However, a gap existed between perception and actual care-seeking behaviours which could contribute to the high rate of maternal deaths associated with these conditions. There were differences in care-seeking practices among women in the two different areas of Bangladesh, which may reflect sociocultural differences, disparities in economic and educational opportunities, and a discrimination in the availability of care.

    Vertebral haemangiomas are recognized to be one of the commonest benign tumours of the vertebral column, occurring mostly in the thoracic spine. The vast majority of these are asymptomatic. Infrequently, these can turn symptomatic and cause neurological deficit (cord compression) through any of four reported mechanisms: (1) epidural extension; (2) expansion of the involved vertebra(e) causing spinal canal stenosis; (3) spontaneous epidural haemorrhage; (4) pathological burst fracture. Thoracic haemangiomas have been reported to be more likely to produce cord compression than lumbar haemangiomas. A forty-nine year old male with acute onset spinal cord compression from a pathological fracture in a first lumbar vertebral haemangioma. An MRI delineated the haemangioma and extent of bleeding that caused the cord compression. These were confirmed during surgery and the haematoma was evacuated. The spine was instrumented from T12 to L2, and a cement vertebroplasty was performed intra-operatively. Written consent for publication was obtained from the patient. The junctional location of the first lumbar vertebra, and the structural weakness from normal bone being replaced by the haemangioma, probably caused it to fracture under axial loading. This pathological fracture caused bleeding from the vascularized bone, resulting in cord compression.

    Pasteurella multocida causes haemorrhagic septicemia in livestock and wild animals, including elephants. The disease has been reported in Asian elephants in India and Sri Lanka, but to date there have been no reported cases in Thailand. ELISA or indirect hemagglutination assays (IHA) have been demonstrated to be able to detect the antibody against the disease in cattle, but no data are available for elephants. The present study reports a novel in-house indirect ELISA for antibody detection of haemorrhagic septicemia in Asian elephants, and evaluates the sensitivity and specificity of the method using a Bayesian approach. The characteristics of ELISA and IHA were analyzed using a one population Bayesian model assuming conditional dependence between these two diagnostic tests. The IHA was performed as recommended by the World Organization for Animal Health (OIE) manual for haemorrhagic septicemia. An in-house indirect ELISA was developed with a heat extract antigen of P. multocida strain M-1404 (serovar B:2) as a coating antigen and rabbit anti-immunoglobulin G conjugated with horseradish peroxidase (eIgG-HRP). The checkerboard titration method was done using elephant sera immunized with P. multocida bacterin and negative sera from colostrum-deprived elephant calves. The concentrations of heat extract antigen (160μg/ml), sample serum (1:100), and eIgG-HRP (1:1000) were optimal for the assay. The calculated cut-off value was 0.103. Of the elephant sera, 50.59% (43/85) were considered seropositive by ELISA. The sensitivity of the ELISA test was higher than that of the IHA test [median=86.5%, 95% posterior probability interval (PPI)=52.5-98.9%] while the specificity was lower (median=54.1%, PPI=43.6-64.7%). The median sensitivity and specificity of IHA were 80.5% (PPI=43.8-98.0%) and 78.4% (PPI=69.0-87.0%), respectively. These findings suggest that our in-house indirect ELISA can be used as a tool to detect the antibody against haemorrhagic septicemia in Asian

    Summary Background The burden of ischaemic and haemorrhagic stroke varies between regions and over time. With differences in prognosis, prevalence of risk factors, and treatment strategies, knowledge of stroke pathological type is important for targeted region-specific health-care planning for stroke and could inform priorities for type-specific prevention strategies. We used data from the Global Burden of Diseases, Injuries, and Risk Factors Study 2010 (GBD 2010) to estimate the global and regional burden of first-ever ischaemic and haemorrhagic stroke during 1990–2010. Methods We searched Medline, Embase, LILACS, Scopus, PubMed, Science Direct, Global Health Database, the WHO library, and regional databases from 1990 to 2012 to identify relevant studies published between 1990 and 2010. We applied the GBD 2010 analytical technique (DisMod-MR) to calculate regional and country-specific estimates for ischaemic and haemorrhagic stroke incidence, mortality, mortality-to-incidence ratio, and disability-adjusted life-years (DALYs) lost, by age group (aged <75 years, ≥75 years, and in total) and country income level (high-income and low-income and middle-income) for 1990, 2005, and 2010. Findings We included 119 studies (58 from high-income countries and 61 from low-income and middle-income countries). Worldwide, the burden of ischaemic and haemorrhagic stroke increased significantly between 1990 and 2010 in terms of the absolute number of people with incident ischaemic and haemorrhagic stroke (37% and 47% increase, respectively), number of deaths (21% and 20% increase), and DALYs lost (18% and 14% increase). In the past two decades in high-income countries, incidence of ischaemic stroke reduced significantly by 13% (95% CI 6–18), mortality by 37% (19–39), DALYs lost by 34% (16–36), and mortality-to-incidence ratios by 21% (10–27). For haemorrhagic stroke, incidence reduced significantly by 19% (1–15), mortality by 38% (32–43), DALYs lost by 39% (32–44

    Background and purpose: In circulatory shock, melanocortins have life-saving effects likely to be mediated by MC4 receptors. To gain direct insight into the role of melanocortin MC4 receptors in haemorrhagic shock, we investigated the effects of two novel selective MC4 receptor agonists. Experimental approach: Severe haemorrhagic shock was produced in rats under general anaesthesia. Rats were then treated with either the non-selective agonist [Nle4, D-Phe7]α-melanocyte-stimulating hormone (NDP-α-MSH) or with the selective MC4 agonists RO27-3225 and PG-931. Cardiovascular and respiratory functions were continuously monitored for 2 h; survival rate was recorded up to 24 h. Free radicals in blood were measured using electron spin resonance spectrometry; tissue damage was evaluated histologically 25 min or 24 h after treatment. Key results: All shocked rats treated with saline died within 30-35 min. Treatment with NDP-α-MSH, RO27-3225 and PG-931 produced a dose-dependent (13-108 nmol kg-1 i.v.) restoration of cardiovascular and respiratory functions, and improved survival. The three melanocortin agonists also markedly reduced circulating free radicals relative to saline-treated shocked rats. All these effects were prevented by i.p. pretreatment with the selective MC4 receptor antagonist HS024. Moreover, treatment with RO27-3225 prevented morphological and immunocytochemical changes in heart, lung, liver, and kidney, at both early (25 min) and late (24 h) intervals. Conclusions and Implications: Stimulation of MC4 receptors reversed haemorrhagic shock, reduced multiple organ damage and improved survival. Our findings suggest that selective MC4 receptor agonists could have a protective role against multiple organ failure following circulatory shock. PMID:17245369

  18. Is management of hyperglycaemia in acute phase stroke still a dilemma?

    Close monitoring of blood glucose levels during the immediate post-acute stroke phase is of great clinical value, as there is evidence that the risk of neurological deterioration is associated with both hyper- and hypoglycaemia. The aim of this review paper is to summarise the evidence on post-stroke blood glucose management and its impact on clinical outcomes, during the early post-acute stage. Post-stroke hyperglycaemia has been associated with increased cerebral oedema, haemorrhagic transformation, lower likelihood of recanalisation and deteriorating neurological state. Thus, hyperglycaemia during an acute stroke may result in poorer clinical outcomes, infarct progression, poor functional recovery and increased mortality rates. Although hypoglycaemia may also lead to poorer outcomes via further brain injury, it can be readily reversed by glucose administration. In most patients, the goal of regular treatment is euglycaemia and for acute-stroke patients, a reasonable approach is to target control of glucose level at 100-150 mg/dL. Both hypoglycaemia and hyperglycaemia may lead to further brain injury and clinical deterioration; that is the reason these conditions should be avoided after stroke. Yet, when correcting hyperglycaemia, great care should be taken not to switch the patient into hypoglycaemia, and subsequently aggressive insulin administration treatment should be avoided. Early identification and prompt management of hyperglycaemia, especially in acute ischaemic stroke, is recommended. Although the appropriate level of blood glucose during acute stroke is still debated, a reasonable approach is to keep the patient in a mildly hyperglycaemic state, rather than risking hypoglycaemia, using continuous glucose monitoring.

    Historical records describe a disease in North America that clinically resembled dengue haemorrhagic fever during the latter part of the slave-trading period. However, the dengue epidemic that occurred in Cuba in 1981 was the first laboratory-confirmed and clinically diagnosed outbreak of dengue haemorrhagic fever in the Americas. At that time, the presumed source of the dengue type 2 strain isolated during this epidemic was considered controversial, partly because of the limited sequence data and partly because the origin of the virus appeared to be southern Asia. Here, we present a molecular characterisation at the whole-genome level of the original strains isolated at different time points during the epidemic. Phylogenetic trees constructed using Bayesian methods indicated that 1981 Cuban strains group within the Asian 2 genotype. In addition, the study revealed that viral evolution occurred during the epidemic - a fact that could be related to the increasing severity from month to month. Moreover, the Cuban strains exhibited particular amino acid substitutions that differentiate them from the New Guinea C prototype strain as well as from dengue type 2 strains isolated globally.

    Post-partum haemorrhage (PPH) is a potentially life-threatening complication of childbirth occurring in up to 10% of births. The NSW Department of Health (DoH) issued a new evidence-based policy (Framework for Prevention, Early Recognition and Management of Post-partum Haemorrhage) in November 2002. Feedback from maternity units indicated that there were deficiencies in the skills and experience is needed to develop the written protocols and local plans of action required by the Framework. All 96 hospitals in NSW that provide care for childbirth were surveyed. A senior midwife completed a semistructured telephone interview. Ninety four per cent of hospitals had PPH policies. Among hospitals that provided a copy of their policy, 83% were dated after the release of the DoH's Framework, but 22% contained an incorrect definition of PPH. Only 71% of respondents in small rural and urban district hospitals recalled receiving a copy of the Framework. There was considerable variation in the frequency of postnatal observations. Key factors that impede local policy development were resources, entrenched practices and centralised policy development. Enabling factors were effective relationships, the DoH policy directive (Framework), education and organisational issues/time. Greater assistance is needed to ensure that hospitals have the capacity to develop a policy applicable to local needs. Maternity hospitals throughout the state provide different levels of care and NSW DoH policy directives should not be 'one size fits all' documents. Earlier recognition of PPH may be facilitated by routine post-partum monitoring of all women and should be consistent throughout the state, regardless of hospital level.

    Early detection and management of post-traumatic haemorrhage and coagulopathy have been associated with improved outcomes, but local infrastructures, logistics and clinical strategies may differ. To assess local differences in infrastructure, logistics and clinical management of trauma-associated haemorrhage and coagulopathy, we have conducted a web-based survey amongst the delegates to the 15th European Congress of Trauma and Emergency Surgery (ECTES) and the 2nd World Trauma (WT) Congress held in Frankfurt, Germany, 25-27 May 2014. 446/1,540 delegates completed the questionnaire yielding a response rate of 29%. The majority specified to work as consultants/senior physicians (47.3%) in general (36.1%) or trauma/orthopaedic surgery (44.5%) of level I (70%) or level II (19%) trauma centres. Clinical assessment (>80%) and standard coagulation assays (74.6%) are the most frequently used strategies for early detection and monitoring of bleeding trauma patients with coagulopathy. Only 30% of the respondents declared to use extended coagulation assays to better characterise the bleeding and coagulopathy prompted by more individualised treatment concepts. Most trauma centres (69%) have implemented local protocols based on international and national guidelines using conventional blood products, e.g. packed red blood cell concentrates (93.3%), fresh frozen plasma concentrates (93.3%) and platelet concentrates (83%), and antifibrinolytics (100%). 89% considered the continuous intake of anticoagulants including "new oral anticoagulants" and platelet inhibitors as an increasing threat to bleeding trauma patients. This study confirms differences in infrastructure, logistics and clinical practice for the detection and management of trauma-haemorrhage and trauma-associated coagulopathy amongst international centres. Ongoing work will focus on geographical differences.

    The principal objective of this study was to describe the policies reported by French maternity units for the prevention and early management of postpartum haemorrhage (PPH). The second objective was to assess their variation according to hospital level and status. Cross-sectional observational study of French maternity units, from January 2010 to April 2011. The medical supervisor (obstetrician or midwife) of participating maternity wards completed a questionnaire designed to ascertain the unit's protocol for preventing and managing PPH after both vaginal and caesarean deliveries at a gestational age >22 weeks (or a birth weight >500g). The main outcome measure was the percentage of units reporting protocols adhering to the principal criteria for adequate management defined by the 2004 French guidelines for PPH. 252 maternity units participated in the survey. Almost all units had a written protocol for PPH (97.2%). For vaginal deliveries, 82.5% of units had a definition of PPH (>500ml) and 92.8% had a policy of preventive oxytocin use. For caesareans, only 23.8% defined PPH (as >1000ml), 68.8% used manual delivery of the placenta, and 76.9% recommended oxytocin injection immediately after the birth. The first-line medication for PPH was oxytocin (96.3%) and the second-line treatment a prostaglandin (97.5%). Level III maternity units had a definition of haemorrhage for vaginal deliveries more often than did other levels of care (P=0.04). Manual removal of the placenta after caesareans was significantly more frequent in level I than level III units (P=0.008) and in private than other types of maternity units. Medical management of haemorrhage did not differ according to level of care or maternity status. The responses by maternity unit supervisors showed significant improvement in the management of PPH accordingly to the 2004 French guidelines, especially for the third stage of labour. This improvement did not differ between hospitals by levels of care or legal

    The present pair-matched case control study was carried out at Government Medical College Hospital, Nagpur, India, a tertiary care hospital with the objective to devise and validate a risk scoring system for prediction of hemorrhagic stroke. The study consisted of 166 hospitalized CT scan proved cases of hemorrhagic stroke (ICD 9, 431-432), and a age and sex matched control per case. The controls were selected from patients who attended the study hospital for conditions other than stroke. On conditional multiple logistic regression five risk factors- hypertension (OR = 1.9. 95% Cl = 1.5-2.5). raised scrum total cholesterol (OR = 2.3, 95% Cl = 1.1-4.9). use of anticoagulants and antiplatelet agents (OR = 3.4, 95% Cl =1.1-10.4). past history of transient ischaemic attack (OR = 8.4, 95% Cl = 2.1- 33.6) and alcohol intake (OR = 2.1, 95% Cl = 1.3-3.6) were significant. These factors were ascribed statistical weights (based on regression coefficients) of 6, 8, 12, 21 and 8 respectively. The nonsignificant factors (diabetes mellitus, physical inactivity, obesity, smoking, type A personality, history of claudication, family history of stroke, history of cardiac diseases and oral contraceptive use in females) were not included in the development of scoring system. ROC curve suggested a total score of 21 to be the best cut-off for predicting haemorrhag stroke. At this cut-off the sensitivity, specificity, positive predictivity and Cohen's kappa were 0.74, 0.74, 0.74 and 0.48 respectively. The overall predictive accuracy of this additive risk scoring system (area under ROC curve by Wilcoxon statistic) was 0.79 (95% Cl = 0.73-0.84). Thus to conclude, if substantiated by further validation, this scorincy system can be used to predict haemorrhagic stroke, thereby helping to devise effective risk factor intervention strategy.

    Native T1 mapping and late gadolinium enhancement (LGE) imaging offer detailed characterisation of the myocardium after acute myocardial infarction (AMI). We evaluated the effects of microvascular injury (MVI) and intramyocardial haemorrhage on local T1 and T2* values in patients with a reperfused AMI. Forty-three patients after reperfused AMI underwent cardiovascular magnetic resonance imaging (CMR) at 4 [3-5] days, including native MOLLI T1 and T2* mapping, STIR, cine imaging and LGE. T1 and T2* values were determined in LGE-defined regions of interest: the MI core incorporating MVI when present, the core-adjacent MI border zone (without any areas of MVI), and remote myocardium. Average T1 in the MI core was higher than in the MI border zone and remote myocardium. However, in the 20 (47%) patients with MVI, MI core T1 was lower than in patients without MVI (MVI 1048±78ms, no MVI 1111±89ms, p=0.02). MI core T2* was significantly lower in patients with MVI than in those without (MVI 20 [18-23]ms, no MVI 31 [26-39]ms, p<0.001). The presence of MVI profoundly affects MOLLI-measured native T1 values. T2* mapping suggested that this may be the result of intramyocardial haemorrhage. These findings have important implications for the interpretation of native T1 values shortly after AMI. • Microvascular injury after acute myocardial infarction affects local T1 and T2* values. • Infarct zone T1 values are lower if microvascular injury is present. • T2* mapping suggests that low infarct T1 values are likely haemorrhage. • T1 and T2* values are complimentary for correctly assessing post-infarct myocardium.

    Being highly pathogenic for human and nonhuman primates and the subject of former weapon programmes makes Ebola virus one of the most feared pathogens worldwide today. Due to a lack of licensed pre- and postexposure intervention, the current response depends on rapid diagnostics, proper isolation procedures and supportive care of case patients. Consequently, the development of more specific countermeasures is of high priority for the preparedness of many nations. Over the past years, enhanced research efforts directed to better understand virus replication and pathogenesis have identified potential new targets for intervention strategies. The authors discuss the most promising therapeutic approaches for Ebola haemorrhagic fever as judged by their efficacy in animal models. The current development in this field encourages discussions on how to move some of the experimental approaches towards clinical application.

    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

In the rare case, the disease leads to renal and hepatic involvement with hemorrhage which may be associated with multisystem organ dysfunction in form of pulmonary, cardiac and central nervous system, when it is known as Weil's disease. Rarely haemorrhagic manifestations are assosciated. Early diagnosis is important as sometimes the disease may be life threatening. Proper antibiotics results in dramatic improvement. We hereby presented a case that had clinical features of Weil's disease with cough, dyspnoea and haemoptysis. Leptospirosis was detected on ELISA testing. Patient was cured rapidly with antibiotics.

    The Crimean-Congo haemorrhagic fever virus (CCHFV) is a 3-segmented RNA virus, which causes disease with a high fatality rate in humans. An inactivated suckling mouse brain-derived vaccine is used in Bulgaria for protection against CCHF. Strain V42/81 is currently used for the vaccine preparation. As the M-RNA segment plays a major role in the immune response, the full-length M segment sequence of the V42/81 strain was characterized. A great genetic diversity was observed among CCHFV strains. In order to gain an insight into the topology of the strain in the CCHFV phylogenetic trees, the full-length S and partial L segments were additionally sequenced and analyzed.

Treatment was continued for 41 hours, including labour and the first three hours after delivery. There was slow but severe postpartum haemorrhage. Partial uterine atony occurred, and may have been due, at least in part, to fibrin degradation products arising from thrombolysis. No adverse effects were noted in the baby. Our experience suggests that streptokinase may be given during labour but that an oxytocic agent may be needed; and that reversal of fibrinolysis before delivery is best achieved by the use of aprotinin (Trasylol) rather than aminocaproic acid.

    Esophageal varices (EV) are a marker of disease severity in compensated cirrhosis due to hepatitis B virus (HBV) which predicts also the risk of hepatocellular carcinoma (HCC), clinical decompensation and anticipated liver related death. The dynamics and prognostic significance of EV in patients under long-term HBV suppression by nucleos(t)ide analogs (NUC), are poorly known. A standardized protocol (Baveno) including 414 upper gastrointestinal (GI) endoscopies was applied to 107 HBeAg-negative compensated cirrhotic patients (93% Child-Pugh A) during a median of 12 (range 2 to 17) years of NUC therapy. Patients who initially started on lamivudine (LMV) and then developed resistance (LMV-R), were rescued by early administration of adefovir, or were switched to tenofovir. Surveillance included serum HBV DNA every three months and abdominal ultrasound every six months. Twenty-seven patients had baseline F1 EV which regressed in 18, remained unchanged in eight and progressed in one patient; the 12-year cumulative incidence of EV regression was 83% (95% CI: 52-92%). De novo F1/F2 EV developed in 6/80 patients with a 12-year cumulative incidence of 10% (95% CI: 5-20%). Six of seven patients with de novo varices or progression of pre-existing varices had either a clinical breakthrough due to LMV-R and/or developed a HCC. No bleedings from ruptured EV occurred, 12 patients died (9 HCC) and 15 were transplanted (13 HCC): the 12-year cumulative incidence of HCC and overall survival was 33% (95% CI: 24-42%) and 76% (95% CI: 67-83%), respectively. Long-term pharmacological suppression of HBV in HBeAg-seronegative patients with compensated cirrhosis leads to a significant regression of pre-existing EV accompanied by a negligible risk of developing de novo EV.

Irrespective of cause, sudden evisceration of an umbilical hernia is associated with deterioration and a poor outcome. Our first case was a 42-year-old woman who presented with sudden outpouring of fluid from the umbilicus with omental evisceration. Further evaluation revealed hepatic decompensation caused by hepatitis C infection belonging to Child-Turcotte-Pugh class C. After stabilizing her hemodynamically, she underwent a partial omentectomy with primary repair of umbilical defect. The patient's postoperative course was challenging. She died of septicemia and acute renal failure after 5 days. Our second case was a 40-year-old man who suffered from alcohol-induced cirrhosis, presenting with omental evisceration, belonging to Child-Turcotte-Pugh class C. We performed a primary repair of the hernial defect with peritoneovenous shunting for his intractable ascites. Upper gastrointestinal endoscopy revealed grade I esophageal varices. The patient succumbed to acute variceal hemorrhage with acute renal failure 18 days later. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: In an emergent setting with multiple factors influencing final surgical outcome, it is imperative that management be tailored for each patient. Those with severe encephalopathy or cardiovascular instability must be stabilized before surgical intervention. Central venous and blood pressures need to be closely monitored during resuscitation, as fervent fluid administration may predispose to variceal hemorrhage. It may be prudent to follow the principle of hypotensive resuscitation as in acute trauma cases. Copyright © 2018 Elsevier Inc. All rights reserved.

    The early diagnosis of pelvic arterial haemorrhage is challenging for initiating treatment by transcatheter arterial embolization (TAE) in multiple trauma patients. We use an institutional algorithm focusing on haemodynamic status on admission and on a whole-body CT scan in stabilized patients to screen patients requiring TAE. This study aimed to assess the effectiveness of this approach. This retrospective cohort study included 106 multiple trauma patients admitted to the emergency room with serious pelvic fracture [pelvic abbreviated injury scale (AIS) score of 3 or more]. Of the 106 patients, 27 (25%) underwent pelvic angiography leading to TAE for active arterial haemorrhage in 24. The TAE procedure was successful within 3h of arrival in 18 patients. In accordance with the algorithm, 10 patients were directly admitted to the angiography unit (n=8) and/or operating room (n=2) for uncontrolled haemorrhagic shock on admission. Of the remaining 96 stabilized patients, 20 had contrast media extravasation on pelvic CT scan that prompted pelvic angiography in 16 patients leading to TAE in 14. One patient underwent a pelvic angiography despite showing no contrast media extravasation on pelvic CT scan. All 17 stabilized patients who underwent pelvic angiography presented a more severely compromised haemodynamic status on admission, and they required more blood products during their initial management than the 79 patients who did not undergo pelvic angiography. The incidence of unstable pelvic fractures was however comparable between the two groups. Overall, haemodynamic instability and contrast media extravasation on the CT-scan identified 26 out of the 27 patients who required subsequent pelvic angiography leading to TAE in 24. An algorithm focusing on haemodynamic status on arrival and on the whole-body CT scan in stabilized patients may be effective at triaging multiple trauma patients with serious pelvic fractures.

    Until the beginning of this decade, the genetic characterization of rabbit haemorrhagic disease virus (RHDV) from Iberian Peninsula had revealed the existence of two genogroups, G1 and sporadically G6. In 2010, the new emerging rabbit haemorrhagic disease variant, RHDV2 or RHDVb, was described in France, from where it has rapidly spread throughout Europe, including Iberian Peninsula countries. Nevertheless, although cases of rabbit haemorrhagic disease (RHD) have been reported in the Canary Islands, a Spanish archipelago located 100km off the coast of Morocco, no genetic characterization of RHDV had been carried out. Consequently, in order to identify the circulating RHDV strains in this archipelago, liver samples of six farm rabbits and fifteen wild rabbits were collected from several areas of the largest island, Tenerife, and analyzed for the presence of RHDV by antigen capture double antibody sandwich ELISA. In case of positive ELISA result, we amplified and sequenced two fragments of the vp60 gene, which were concatenated for phylogenetic purposes. The sequences analysis revealed the presence of RHDV2 in both farm and wild rabbits from several areas of Tenerife. This result constitutes the first finding of RHDV2 in the Canary Islands. These RHDV2 strains found in Tenerife shared two exclusive SNPs that have not been observed in the rest of RHDV2 strains. The identification of RHDV2 and the absence of classic RHDV strains in this study suggest that RHDV2 may be replacing classic strains in Tenerife, as has been also proposed in Iberian Peninsula, France and Azores. Given the proximity of the Canary Islands to the African continent, this result should raise awareness about a possible dispersal of RHDV2 from the Canary Islands to the North of Africa.

    Vasospasm and other secondary neurological insults may follow subarachnoid haemorrhage (SAH). Biomarkers have the potential to stratify patient risk and perhaps serve as an early warning sign of delayed ischaemic injury. Serial cerebrospinal fluid (CSF) samples were collected from 38 consecutive patients with aneurysmal SAH admitted to the neurosurgical intensive care unit. We measured heart-fatty acid-binding protein (H-FABP) and tau protein (τ) levels in the CSF to evaluate their association with brain damage, and their potential as predictors of the long-term outcome. H-FABP and τ were analysed in relation to acute clinical status, assessed by the World Federation of Neurological Surgeons (WFNS) scale, radiological findings, clinical vasospasm, and 6-month outcome. H-FABP and τ increased after SAH. H-FABP and τ were higher in patients in poor clinical status on admission (WFNS 4-5) compared with milder patients (WFNS 1-3). Elevated H-FABP and τ levels were also observed in patients with early cerebral ischaemia, defined as a CT scan hypodense lesion visible within the first 3 days after SAH. After the acute phase, H-FABP, and τ showed a delayed increase with the occurrence of clinical vasospasm. Finally, patients with the unfavourable outcome (death, vegetative state, or severe disability) had higher peak levels of both proteins compared with patients with good recovery or moderate disability. H-FABP and τ show promise as biomarkers of brain injury after SAH. They may help to identify the occurrence of vasospasm and predict the long-term outcome.

    Viral haemorrhagic fevers (VHFs) represent a challenge for public health because of their epidemic potential, and their possible use as bioterrorism agents poses particular concern. In 1999 the World Health Organization (WHO) proposed a case definition for VHFs, subsequently adopted by other international institutions with the aim of early detection of initial cases/outbreaks in western countries. We applied this case definition to reports of Ebola and Marburg virus infections to estimate its sensitivity to detect cases of the disease. We analyzed clinical descriptions of 795 reported cases of Ebola haemorrhagic fever: only 58.5% of patients met the proposed case definition. A similar figure was obtained reviewing 169 cases of Marburg diseases, of which only 64.5% were in accordance with the case definition. In conclusion, the WHO case definition for hemorrhagic fevers is too specific and has poor sensitivity both for case finding during Ebola or Marburg outbreaks, and for early detection of suspected cases in western countries. It can lead to a hazardous number of false negatives and its use should be discouraged for early detection of cases.

    Background and study aims: Many patients with acute gastrointestinal bleeding present with anemia and frequently require red blood cell (RBC) transfusion. A restrictive transfusion strategy and a low hemoglobin (Hb) threshold for transfusion had been shown to produce acceptable outcomes in patients with acute upper gastrointestinal bleeding. However, most patients are discharged with mild anemia owing to the restricted volume of packed RBCs (pRBCs). We investigated whether discharge Hb influences the outcome in patients with acute nonvariceal upper gastrointestinal bleeding. Patients and methods: We retrospectively analyzed patients with upper gastrointestinal bleeding who had received pRBCs during hospitalization between January 2012 and January 2014. Patients with variceal bleeding, malignant lesion, stroke, or cardiovascular disease were excluded. We divided the patients into 2 groups, low (8 g/dL ≤ Hb < 10 g/dL) and high (Hb ≥ 10 [g/dL]) discharge Hb, and compared the clinical course and Hb changes between these groups. Results: A total of 102 patients met the inclusion criteria. Fifty patients were discharged with Hb levels < 10 g/dL, whereas 52 were discharged with Hb levels > 10 g/dL. Patients in the low Hb group had a lower consumption of pRBCs and shorter hospital stay than did those in the high Hb group. The Hb levels were not fully recovered at outpatient follow-up until 7 days after discharge; however, most patients showed Hb recovery at 45 days after discharge. The rate of rebleeding after discharge was not significantly different between the 2 groups. Conclusions: In patients with acute upper gastrointestinal bleeding, a discharge Hb between 8 and 10 g/dL was linked to favorable outcomes on outpatient follow-up. Most patients recovered from anemia without any critical complication within 45 days after discharge.

    Objective To investigate the technical and clinical outcomes of plug-assisted retrograde transvenous obliteration (PARTO) for the treatment of gastric varices (GV) and to evaluate the role of intra-procedural cone-beam computed tomography (CBCT) performed during PARTO to confirm its technical success. Materials and Methods From January 2016 to December 2016, 17 patients with GV who had undergone PARTO were retrospectively evaluated. When the proximal part of the afferent vein was identified on a fluoroscopy, non-contrast CBCT images were obtained. In patients with incomplete embolization of GV, an additional injection of gelatin sponges was performed. Follow-up data from contrast-enhanced CT and upper intestinal endoscopy, as well as clinical and laboratory data were collected. Results Plug-assisted retrograde transvenous obliteration procedures were technically successful in all 17 patients. Complete embolization of GV was detected on CBCT images in 15 patients; whereas, incomplete embolization was detected in two. Complete embolization of GV was then achieved after an additional injection of gelatin sponges in these two patients as demonstrated on the 2nd CBCT image. The mean follow-up period after PARTO was 193 days (range, 73–383 days). A follow-up CT obtained 2–4 months after PARTO demonstrated marked shrinkage or complete obliteration of GV and portosystemic shunts in all 17 patients. There were no cases of variceal bleeding during the follow-up. Conclusion Plug-assisted retrograde transvenous obliteration is technically and clinically effective for the treatment of GV. In addition, intra-procedural CBCT can be an adjunct tool to fluoroscopy, because it can provide an immediate and accurate evaluation of the technical success of PARTO. PMID:29520179

    Context Vertebral haemangiomas are recognized to be one of the commonest benign tumours of the vertebral column, occurring mostly in the thoracic spine. The vast majority of these are asymptomatic. Infrequently, these can turn symptomatic and cause neurological deficit (cord compression) through any of four reported mechanisms: (1) epidural extension; (2) expansion of the involved vertebra(e) causing spinal canal stenosis; (3) spontaneous epidural haemorrhage; (4) pathological burst fracture. Thoracic haemangiomas have been reported to be more likely to produce cord compression than lumbar haemangiomas. Findings A forty-nine year old male with acute onset spinal cord compression from a pathological fracture in a first lumbar vertebral haemangioma. An MRI delineated the haemangioma and extent of bleeding that caused the cord compression. These were confirmed during surgery and the haematoma was evacuated. The spine was instrumented from T12 to L2, and a cement vertebroplasty was performed intra-operatively. Written consent for publication was obtained from the patient. Clinical Relevance The junctional location of the first lumbar vertebra, and the structural weakness from normal bone being replaced by the haemangioma, probably caused it to fracture under axial loading. This pathological fracture caused bleeding from the vascularized bone, resulting in cord compression. PMID:21756575

    Hantavirus is an RNA virus that can cause potentially fatal pulmonary and renal diseases in humans. Infections with Hantaviruses occur through inhalation of aerosol from rodent faeces, urine or saliva. The predominant virus type in Denmark is the Puumala virus, which causes the mildest form of haemorrhagic fever with renal syndrome, the so-called nephropathia epidemica (NE) with good prognosis (mortality 0.1-0.4%). The incidence of Hantavirus-infection in Denmark is about ten cases a year. The diagnosis of Hantavirus-infection is based on serology and/or polymerase chain reaction in blood or urine.

    Objective Patients with intracerebral haemorrhage (ICH) are at high risk of neurological deterioration (ND). We aimed at establishing predictors of early ND (END) as well as late ND (LND) and at exploring the impact of neurological stability during the first week on long-term prognosis. Design We conducted this study as a retrospective cohort study. ND was evaluated based on the consciousness and severity of neurological symptoms. ND during the first 24 h after admission was defined as early ND and from 24 h to 7 days as LND. Patients were followed up until February 2015. Participants We included 300 patients with acute ICH (≤4.5 h from symptom onset) who were admitted to our institution from March 2009 to January 2015. Setting Section of Acute Neurology, Department of Neurology, Bispebjerg Hospital is a specialised referral centre receiving patients with acute stroke from the entire capital region of Denmark. Results We found that a spot sign on CT angiography (OR 10.7 CI 4.79 to 24.3) and extensive degree of interventricular haemorrhage (IVH) (OR 8.73 CI 2.87 to 26.5) were independent predictors of END, whereas a degree of comorbidity (Charlton Index), admission stroke severity and degree of IVH predicted LND. On follow-up imaging, haematoma expansion was independently associated with END (OR 6.1 CI 2.2 to 17.3), and expansion of IVH was independently associated with both END (OR 1.7 CI 1.2 to 2.3 per point increase) and LND (OR 2.3 CI 1.3 to 4.2 per point increase). ND during the first week was associated with a 1-year mortality of 60.5%, compared with 9.2% among the patients who remained stable. Conclusions These results suggest that stability during the first week entails an optimistic prognosis. A relatively easy and effective risk stratification of END and LND is possible on admission based on the spot sign, IVH and clinical parameters. PMID:26220872

    We aimed to investigate the role of pretreatment collateral status in predicting the efficacy and safety of endovascular treatment (EVT) in acute ischaemic stroke due to cervical and/or cerebral arterial occlusions. Relevant full-text articles published since 1 January 2000, investigating correlations between collateral status and any efficacy or safety outcome in patients undergoing EVT in cohort or case-control studies, or randomised clinical trials, were retrieved by PubMed and manual search. Two authors extracted data from eligible studies and assessed study quality. Risk ratios (RR) were pooled for good versus poor collaterals for outcomes based on a random-effects model. Sensitivity and subgroup analyses were conducted. In total, 35 (3542 participants) and 23 (2652 participants) studies were included in qualitative review and quantitative meta-analysis, respectively. Overall, good pretreatment collaterals increased the rate of favourable functional outcome at 3 months (RR=1.98, 95% CI 1.64 to 2.38; p<0.001), and reduced the risks of periprocedural symptomatic intracranial haemorrhage (RR=0.59, 95% CI 0.43 to 0.81; p=0.001) and 3-month mortality (RR=0.49, 95% CI 0.38 to 0.63; p<0.001), as compared with poor collaterals, in patients with acute ischaemic stroke under EVT. No individual study could alter the estimate of overall effect of collateral status, but there were moderate to significant heterogeneities between subgroups of studies with different modes of EVT, different arterial occlusions and different collateral grading methods. Good pretreatment collateral status is associated with higher rates of favourable functional outcome, and lower rates of symptomatic intracranial haemorrhage and mortality, in patients with acute ischaemic stroke receiving endovascular therapies.

    Abdominal crises (vaso-occlusive) are not infrequent in patients with sickle cell anemia. They usually present as acute abdomen. These patients none the less present with other causes of acute abdomen like others without hemoglobinopathy. Six cases of surgical acute abdomen in sickle cell disease patients treated in the University of Port Harcourt Teaching Hospital (UPTH) are presented. Six sickle cell anaemia patients presenting with acute abdominal conditions from 1999 to 2008 (inclusive) in the University of Port Harcourt Teaching Hospital were studied retrospectively (two patients) and prospectively (four patients). After initial resuscitation, appropriate surgical procedures, namely, appendicectomy (2), cholecystectomy (1), open drainage of splenic abscess (1), and release of adhesive band (1) were performed. Six cases were treated (female/male ratio 2:1). Four patients were in the 11-20 year age group. Two patients had appendicectomy and two presented with acute cholecystitis/cholelithiasis, one of whom had open cholecystectomy. One young girl had drainage of splenic abscess and a 42-year-old male had division of obstructive adhesive band at laparotomy. There were two complications, namely, postoperative haemorrhage (in cholecystectomy patient) and acute chest syndrome (in one appendicectomy patient). These were successfully managed with blood transfusion and antibiotic/oxygen therapy, respectively. There was no mortality. Sickle cell anaemia patients are not exempt from acute abdominal conditions requiring surgery. A high index of suspicion coupled with repeated clinical examination is needed for early diagnosis and appropriate treatment.

    Background It has been proposed that portal-systemic shunts be avoided in alcoholic cirrhotics because survival rate is allegedly lower in alcoholics than in nonalcoholics. We examined this issue in a randomized controlled trial. Methods 211 unselected, consecutive patients with cirrhosis and bleeding esophageal varices were randomized to endoscopic sclerotherapy (EST) (n=106) or emergency portacaval shunt (EPCS) (105). Treatment was initiated within 8 hours. EST failure was treated by rescue PCS. 10-yr follow-up was 96%. Results Results strongly favored EPCS over EST (p<0.001). Among EPCS patients, 83% were alcoholic and 17% nonalcoholic. Outcomes were (1) permanent control of bleeding 100% vs. 100%; (2) 5-yr survival 71% vs.78%; (3) encephalopathy 14% vs. 19%; (4) yearly charges $38,300 vs. $43,000. Conclusions EPCS results were similar in alcoholic and nonalcoholic cirrhotics. EPCS is an effective first line emergency treatment in all forms of cirrhosis, including alcoholic. PMID:21195430

    The optimal treatment for patients with ischaemic stroke with a high risk of cerebral haemorrhage is unclear. We assessed the efficacy and safety of cilostazol versus aspirin, with and without probucol, in these patients. In this randomised, controlled, 2 × 2 factorial trial, we enrolled patients with ischaemic stroke with a history of or imaging findings of intracerebral haemorrhage or two or more microbleeds from 67 centres in three Asian countries. Patients were randomly assigned (1:1:1:1) to receive oral cilostazol (100 mg twice a day), aspirin (100 mg once a day), cilostazol plus probucol (250 mg twice a day), or aspirin plus probucol with centralised blocks stratified by centre. Cilostazol versus aspirin was investigated double-blinded; probucol treatment was open-label, but the outcome assessor was masked to assignment. The co-primary outcomes were incidence of the composite of stroke, myocardial infarction, or vascular death (efficacy) and incidence of haemorrhagic stroke (safety), which were assessed in intention-to-treat and modified intention-to-treat populations. Efficacy was analysed with a non-inferiority test and a superiority test if non-inferiority was satisfied. Safety was assessed with a superiority test only. This trial is registered with ClinicalTrials.gov, NCT01013532. Between Aug 1, 2009, and Aug 31, 2015, we randomly assigned 1534 patients to one of the four study groups, of whom 1512 were assessed for the co-primary endpoints. During a median follow-up of 1·9 years (IQR 1·0-3·0), the incidence of composite vascular events was 4·27 per 100 person-years in patients who received cilostazol and 5·33 per 100 person-years in patients who received aspirin (HR 0·80, 95% CI 0·57-1·11; non-inferiority p=0·0077; superiority p=0·18). Incidence of cerebral haemorrhage was 0·61 per 100 person-years in patients who received cilostazol and 1·20 per 100 person-years in those who received aspirin (HR 0·51, 97·5% CI 0·20-1·27; superiority

    Cases of splanchnic venous thrombosis have not been described in Cameroon. Their prevalence in acute pancreatitis is variable. With the emergence of acute intra-abdominal infections including typhoid fever and peritoneal tuberculosis in situations of acquired immunodeficiency syndrome, these cases will become frequent. We report the case of a portosplenomesenteric venous thrombosis related to necrotizing acute pancreatitis associated with proteins C and S deficiency, in a 46-year-old Cameroonian man, without particular past medical history. He was admitted for abdominal pain which had been evolving for 3 weeks and accompanied by vomiting. In the absence of hemorrhagic risk factor, the patient received low molecular weight heparin followed by oral warfarin. The abdominal ultrasound check on the 12th day showed a partial recanalization of venous thrombosis. The abdominal contrast-enhanced CT scanner at day 30 on oral anticoagulation therapy showed collateral vessels and small bowel edema. At the same time the upper gastrointestinal endoscopy showed grade II esophageal varices. We have maintained oral anticoagulation therapy. This case highlights that an early effective anticoagulation heparin therapy is needed for a clear benefit in case of suspected PSMVT. It is certain that the sooner the treatment is given, the better outcome will be.

    Haemorrhagic shock is the leading cause of early preventable death in severe trauma. Delayed treatment is a recognized prognostic factor that can be prevented by efficient organization of care. This study aimed to develop and validate Red Flag, a binary alert identifying blunt trauma patients with high risk of severe haemorrhage (SH), to be used by the pre-hospital trauma team in order to trigger an adequate intra-hospital standardized haemorrhage control response: massive transfusion protocol and/or immediate haemostatic procedures. A multicentre retrospective study of prospectively collected data from a trauma registry (Traumabase®) was performed. SH was defined as: packed red blood cell (RBC) transfusion in the trauma room, or transfusion ≥ 4 RBC in the first 6 h, or lactate ≥ 5 mmol/L, or immediate haemostatic surgery, or interventional radiology and/or death of haemorrhagic shock. Pre-hospital characteristics were selected using a multiple logistic regression model in a derivation cohort to develop a Red Flag binary alert whose performances were confirmed in a validation cohort. Among the 3675 patients of the derivation cohort, 672 (18%) had SH. The final prediction model included five pre-hospital variables: Shock Index ≥ 1, mean arterial blood pressure ≤ 70 mmHg, point of care haemoglobin ≤ 13 g/dl, unstable pelvis and pre-hospital intubation. The Red Flag alert was triggered by the presence of any combination of at least two criteria. Its predictive performances were sensitivity 75% (72-79%), specificity 79% (77-80%) and area under the receiver operating characteristic curve 0.83 (0.81-0.84) in the derivation cohort, and were not significantly different in the independent validation cohort of 2999 patients. The Red Flag alert developed and validated in this study has high performance to accurately predict or exclude SH.

    Between April 1980 and March 1986, 19 infants underwent cerebrospinal fluid (CSF) shunting procedures for post-haemorrhagic ventricular dilatation at the Hammersmith Hospital, London. A total of 58 shunt-related procedures have been performed on these children. The major perioperative complication was seizure activity (eight children). Postoperative complications included infection (12 shunts) and blockage (29 shunts). Prophylactic antibiotics failed to prevent shunt infection. The likelihood of the first shunt failing was significantly reduced by greater weight of the infant and lower CSF protein at surgery. Long-term outcome was poor: three have died and another four are quadriplegic with severe mental retardation. Only four children are developmentally normal. These outcomes cannot be related to the shunt surgery or its complications, but correlate best with pre-operative parenchymal brain-lesions, as shown on ultrasound scans.

    Dengue is the most important human viral disease transmitted by mosquitoes. It can be asymptomatic or it can present in any of its 3clinical forms: Dengue fever, dengue haemorrhagic fever and dengue shock syndrome. However, some atypical manifestations have been reported in surgical emergencies caused by acute appendicitis in patients with dengue fever. We report the case of an 18-year-old Mexican male who presented to the emergency department of the General Hospital of Culiacan, Sinaloa, with symptoms of dengue fever, accompanied by crampy abdominal pain with positive Rovsing and Dunphy signs. Dengue infection was confirmed by a positive NS1 antigen test performed by enzyme-linked immunosorbent assay. An abdominal ultrasound revealed an appendicular process; as the abdominal pain in the right side kept increasing, an open appendectomy was performed. Abundant inflammatory liquid was observed during the surgery, and the pathology laboratory reported an oedematous appendix with fibrinopurulent plaques, which agreed with acute ulcerative appendicitis. The patient was discharged fully recovered without complications during the follow-up period. Acute abdominal pain can be caused in some cases by dengue infection. This can be confusing, which can lead to unnecessary surgical interventions, creating additional morbidities and costs for the patient. This unusual and coincident acute appendicitis with dengue highlights the importance of performing careful clinical studies for appropriate decision making, especially in dengue endemic regions during an outbreak of this disease.

    Background Crimean-Congo Haemorrhagic fever Virus (CCHFV) is a rapidly emerging vector-borne pathogen and the cause of a virulent haemorrhagic fever affecting large parts of Europe, Africa, the Middle East and Asia. Methodology/principle findings An isothermal recombinase polymerase amplification (RPA) assay was successfully developed for molecular detection of CCHFV. The assay showed rapid (under 10 minutes) detection of viral extracts/synthetic virus RNA of all 7 S-segment clades of CCHFV, with high target specificity. The assay was shown to tolerate the presence of inhibitors in crude preparations of mock field samples, indicating that this assay may be suitable for use in the field with minimal sample preparation. The CCHFV RPA was successfully used to screen and detect CCHFV positives from a panel of clinical samples from Tajikistan. Conclusions/significance The assay is a rapid, isothermal, simple-to-perform molecular diagnostic, which can be performed on a light, portable real-time detection device. It is ideally placed therefore for use as a field-diagnostic or in-low resource laboratories, for monitoring of CCHF outbreaks at the point-of-need, such as in remote rural regions in affected countries.

    To report the 12 months efficacy of initial intravitreal bevacizumab or intravitreal recombinant tissue plasminogen activator (rtPA) combined with expansile gas in patients with subretinal haemorrhage caused by neovascular age-related macular degeneration (AMD). Forty-five eyes of 45 patients with subretinal haemorrhage (1-5 disc diameters) involving the fovea secondary to neovascular AMD were evaluated retrospectively consecutively. Thirty-two eyes underwent treatment with rtPA (50 μg/0.05 ml) combined with intravitreal sulphur hexafluoride (SF6). The other 13 eyes were treated with bevacizumab (1.25 mg/0.05 ml) and SF6. Thereafter, all patients received Vascular Endothelial Growth Factor (anti-VEGF) treatment according to modified PrONTO criteria. Main outcome was change of best-corrected visual acuity (VA) at 12 months as determined by Early Treatment Diabetic Retinopathy (ETDRS). There was more improvement in patients initially treated with rtPA and gas (14 letters; bevacizumab and gas eight letters) and not suffering from adverse events. The incidence of vitreous haemorrhages was significantly higher in the rtPA group (nine of 32 versus one of 13, p < 0.01). In both groups, an average of 3.5 anti-VEGF injections were performed per patient during 12 months (no difference between both groups). Both initial treatment regimen lead to improved functional results after 1 year. However, patients, not suffering from adverse events, who underwent initial treatment with rtPA and gas showed better results. To maintain VA, controlling neovascular AMD by anti-VEGF treatment regime after initial treatment with rtPA+gas is important for all cases. © 2011 The Authors.

    Dengue haemorrhagic fever (DHF) is a prevalent acute disease that occurs in patients infected by an arbovirus in tropical and subtropical regions. We have previously shown increased intraplatelet nitric oxide (NO) production in patients with dengue fever associated with reduced platelet aggregation. In this study, l-arginine transport as well as expression and activity of nitric oxide synthase (NOS) isoforms in the presence or absence of l-arginine analogues were examined in 23 DHF patients. l-arginine transport and NOS activity in platelets were increased in patients with DHF compared with controls. However, platelet endothelial NOS (eNOS) and inducible (iNOS) protein levels did not differ between healthy controls and DHF patients. Endogenous or exogenous analogues did not inhibit platelet NOS activity from DHF patients. In contrast, endogenous l-arginine analogues [N(G)-monomethyl-l-arginine (l-NMMA) and asymmetric dimethylarginine (ADMA)] inhibited NOS activity in platelets from healthy subjects. These results show the first evidence that the intraplatelet l-arginine-NO pathway is activated in DHF patients. The lack of inhibition of NO formation in vitro by all l-arginine analogues tested in DHF platelets may suggest another mechanism by which NOS activity can be regulated.

    The study of neoplasia in wildlife species contributes to the understanding of cancer biology, management practices, and comparative pathology. Higher frequencies of neoplasms among captive non-domestic felids have been reported most commonly in aging individuals. However, testicular tumours have rarely been reported. This report describes a metastatic testicular sex cord-stromal tumour leading to fatal haemorrhage and thrombosis in a captive African lion (Panthera leo). During necropsy of a 16-year-old male African lion, the left testicle and spermatic cord were found to be intra-abdominal (cryptorchid), semi-hard and grossly enlarged with multiple pale-yellow masses. Encapsulated haemorrhage was present in the retroperitoneum around the kidneys. Neoplastic thrombosis was found at the renal veins opening into the caudal vena cava. Metastases were observed in the lungs and mediastinal lymph nodes. Histology revealed a poorly differentiated pleomorphic neoplasm comprised of round to polygonal cells and scattered spindle cells with eosinophilic cytoplasm. An immunohistochemistry panel of inhibin-α, Ki-67, human placental alkaline phosphatase, cytokeratin AE1/AE3, cKit, vimentin and S100 was conducted. Positive cytoplasmic immunolabeling was obtained for vimentin and S100. The gross, microscopic and immunohistochemical findings of the neoplasm were compatible with a poorly differentiated pleomorphic sex cord-stromal tumour. Cause of death was hypovolemic shock from extensive retroperitoneal haemorrhage and neoplastic thrombosis may have contributed to the fatal outcome. To our knowledge, this is the first report of sex cord-stromal tumour in non-domestic felids.

    Identifying the appropriate long-term anti-thrombotic therapy following acute ischaemic stroke is a challenging area in which computer-based decision support may provide assistance. To evaluate the influence on prescribing practice of a computer-based decision support system (CDSS) that provided patient-specific estimates of the expected ischaemic and haemorrhagic vascular event rates under each potential anti-thrombotic therapy. Cluster-randomized controlled trial. We recruited patients who presented for a first investigation of ischaemic stroke or TIA symptoms, excluding those with a poor prognosis or major contraindication to anticoagulation. After observation of routine prescribing practice (6 months) in each hospital, centres were randomized for 6 months to either control (routine practice observed) or intervention (practice observed while the CDSS provided patient-specific information). We compared, between control and intervention centres, the risk reduction (estimated by the CDSS) in ischaemic and haemorrhagic vascular events achieved by long-term anti-thrombotic therapy, and the proportions of subjects prescribed the optimal therapy identified by the CDSS. Sixteen hospitals recruited 1952 subjects. When the CDSS provided information, the mean relative risk reduction attained by prescribing increased by 2.7 percentage units (95%CI -0.3 to 5.7) and the odds ratio for the optimal therapy being prescribed was 1.32 (0.83 to 1.80). Some 55% (5/9) of clinicians believed the CDSS had influenced their prescribing. Cluster-randomized trials provide excellent frameworks for evaluating novel clinical management methods. Our CDSS was feasible to implement and acceptable to clinicians, but did not substantially influence prescribing practice for anti-thrombotic drugs after acute ischaemic stroke.

    To investigate the benefit of supplementing amoxicillin-clavulanic acid therapy with metronidazole in dogs presenting to a primary care veterinary practice with severe haemorrhagic diarrhoea. Prospective randomised blinded trial on dogs presenting with haemorrhagic diarrhoea of less than 3 days duration to a primary care veterinary hospital and also requiring intravenous fluid therapy. Cases were randomised to receive either metronidazole or saline, in addition to standard supportive therapy consisting of amoxicillin-clavulanic acid, intravenous fluid therapy, buprenorphine and omeprazole. Treatment efficacy was measured by duration of hospitalisation and daily scoring of disease severity. Thirty-four cases successfully completed the trial. There was no significant difference in hospitalisation time between treatment groups (mean for dogs receiving metronidazole was 29.6 hours and for controls was 26.3 hours) nor in daily clinical scores. This study strongly suggests that addition of metronidazole is not an essential addition to amoxicillin-clavulanic acid therapy for treatment of severe cases of haemorrhagic diarrhoea in dogs. © 2018 British Small Animal Veterinary Association.

    Alteplase is effective for treatment of acute ischaemic stroke but debate continues about its use after longer times since stroke onset, in older patients, and among patients who have had the least or most severe strokes. We assessed the role of these factors in affecting good stroke outcome in patients given alteplase. We did a pre-specified meta-analysis of individual patient data from 6756 patients in nine randomised trials comparing alteplase with placebo or open control. We included all completed randomised phase 3 trials of intravenous alteplase for treatment of acute ischaemic stroke for which data were available. Retrospective checks confirmed that no eligible trials had been omitted. We defined a good stroke outcome as no significant disability at 3-6 months, defined by a modified Rankin Score of 0 or 1. Additional outcomes included symptomatic intracranial haemorrhage (defined by type 2 parenchymal haemorrhage within 7 days and, separately, by the SITS-MOST definition of parenchymal type 2 haemorrhage within 36 h), fatal intracranial haemorrhage within 7 days, and 90-day mortality. Alteplase increased the odds of a good stroke outcome, with earlier treatment associated with bigger proportional benefit. Treatment within 3·0 h resulted in a good outcome for 259 (32·9%) of 787 patients who received alteplase versus 176 (23·1%) of 762 who received control (OR 1·75, 95% CI 1·35-2·27); delay of greater than 3·0 h, up to 4·5 h, resulted in good outcome for 485 (35·3%) of 1375 versus 432 (30·1%) of 1437 (OR 1·26, 95% CI 1·05-1·51); and delay of more than 4·5 h resulted in good outcome for 401 (32·6%) of 1229 versus 357 (30·6%) of 1166 (OR 1·15, 95% CI 0·95-1·40). Proportional treatment benefits were similar irrespective of age or stroke severity. Alteplase significantly increased the odds of symptomatic intracranial haemorrhage (type 2 parenchymal haemorrhage definition 231 [6·8%] of 3391 vs 44 [1·3%] of 3365, OR 5·55, 95% CI 4·01-7·70, p

    Magnetic Resonance Imaging (MRI) is increasingly available as a tool for assessment of patients presenting to acute services with seizures. We set out to prospectively determine the usefulness of early MRI brain in a cohort of patients presenting with acute seizures. We examined the MR imaging studies performed in patients admitted solely because of acute seizures to Cork University Hospital over a 12-month period. The main aim of the study was to determine if the MRI established the proximate cause for the patient's recent seizure. We identified 91 patients who underwent MRI brain within 48 h of admission for seizures. Of the 91 studies, 51 were normal (56 %). The remaining 40 studies were abnormal as follows: microvascular disease (usually moderate/severe) (n = 19), post-traumatic gliosis (n = 7), remote symptomatic lesion (n = 6), primary brain tumour (n = 5), venous sinus thrombosis (n = 3), developmental lesion (n = 3), post-surgical gliosis (n = 3) and single cases of demyelination, unilateral hippocampal sclerosis, lobar haemorrhage and metastatic malignant melanoma. Abnormalities in diffusion-weighted sequences that were attributable to prolonged ictal activity were seen in nine patients, all of who had significant ongoing clinical deficits, most commonly delirium. Of the 40 patients with abnormal MRI studies, seven patients had unremarkable CT brain. MR brain imaging revealed the underlying cause for acute seizures in 44 % of patients. CT brain imaging failed to detect the cause of the acute seizures in 19 % of patients in whom subsequent MRI established the cause. This study emphasises the importance of obtaining optimal imaging in people admitted with acute seizures.

    We have recently developed a transmissible vaccine to immunize rabbits against myxomatosis and rabbit haemorrhagic disease based on a recombinant myxoma virus (MV) expressing the rabbit haemorrhagic disease virus (RHDV) capsid protein [Bárcena et al. Horizontal transmissible protection against myxomatosis and rabbit haemorragic disease using a recombinant myxoma virus. J. Virol. 2000;74:1114-23]. Administration of the recombinant virus protects rabbits against lethal RHDV and MV challenges. Furthermore, the recombinant virus is capable of horizontal spreading promoting protection of contact animals, thus providing the opportunity to immunize wild rabbit populations. However, potential risks must be extensively evaluated before considering its field use. In this study several safety issues concerning the proposed vaccine have been evaluated under laboratory conditions. Results indicated that vaccine administration is safe even at a 100-fold overdose. No undesirable effects were detected upon administration to immunosuppressed or pregnant rabbits. The recombinant virus maintained its attenuated phenotype after 10 passages in vivo.

    Sub-Saharan Africa and southern Asia account for almost 85% of global maternal deaths from post-partum haemorrhage. Early administration of tranexamic acid, within 3 h of giving birth, was shown to reduce the risk of death due to bleeding in women with post-partum haemorrhage in the World Maternal Antifibrinolytic (WOMAN) trial. We aimed to assess the cost-effectiveness of early administration of tranexamic acid for treatment of post-partum haemorrhage. For this economic evaluation we developed a decision model to assess the cost-effectiveness of the addition of tranexamic acid to usual care for treatment of women with post-partum haemorrhage in Nigeria and Pakistan. We used data from the WOMAN trial to inform model parameters, supplemented by estimates from the literature. We estimated costs (calculated in 2016 US$), life-years, and quality-adjusted life-years (QALYs) with and without tranexamic acid, calculated incremental cost-effectiveness ratios (ICERs), and compared these to threshold values in each country. Costs were assessed from the health-care provider perspective and discounted at 3% per year in the base case analysis. We did a series of one-way sensitivity analyses and probabilistic sensitivity analysis to assess the robustness of the results to parameter uncertainty. Early treatment of post-partum haemorrhage with tranexamic acid generated an average gain of 0·18 QALYs at an additional cost of $37·12 per patient in Nigeria and an average gain of 0·08 QALYs at an additional cost of $6·55 per patient in Pakistan. The base case ICER results were $208 per QALY in Nigeria and $83 per QALY in Pakistan. These ICERs were below the lower bound of the cost-effectiveness threshold range in both countries. The ICERs were most sensitive to uncertainty in parameter inputs for the relative risk of death due to bleeding with tranexamic acid, the discount rate, the cost of the drug, and the baseline probability of death due to bleeding.

    In Senegal, wild ground-feeding birds are frequently infested with immature ticks. In two areas where numerous Crimean-Congo haemorrhagic fever (CCHF) virus isolations were obtained from Hyalomma marginatum rufipes adult ticks collected on ungulates, 175 birds were captured and sera collected. CCHF antibodies were detected by ELISA in 6/22 red-beaked hornbills (Tockus erythrorhynchus), 2/11 glossy starlings (Lamprotornis sp.) and 1/3 guinea fowls. The virus was isolated from H. m. rufipes nymphs collected on a hornbill. The role of wild ground-feeding birds in CCHF virus ecology in West Africa is discussed.

    Dengue Haemorrhagic Fever (DHF) is one of major health problems in Indonesia. DHF is a caused by the dengue virus and potentially deadly infection spread by some mosquitos. The mosquito Aedes aegypti is the main species that spreads this disease. The incidence rate of dengue haemorrhagic fever was still increased in 2011 to 2015 in Indonesia. Dengue viruses and their mosquito vectors are sensitive to their environment. Temperature, rainfall and humidity have well-define roles in the transmission cycle. Therefore changes in these conditions may contribute to increasing incidence. The aim of this study was to analyze the relationship between climate factors and the incidence rate of dengue hemorrhagic fever in Semarang City. The type of research was analytic with cross sectional study. The sample used is the climate data from Meteorology, Climatology and Geophysics Agency (BMKG) and the number of dengue cases from Health Office in Semarang City from 2011 to 2016. Data were analyzed using Pearson trials with α=0,05. Base on this study here air temperature and relative humidity were moderate correlation with negative direction on air temperature (p = 0,000 and r = -0, 429), weakly correlation with positive direction on rainfall (p = 0,014 and r = 0,288) and humidity (p=0,001 and r = 0,382) with dengue hemorrhagic fever incidence in Semarang City. The conclusions of this study there were correlation between climate (air temperature, rainfall, and relative humidity) and DHF in Semarang City in 2011-2016.

    The antifibrinolytic, 6-aminohexanoic acid, also named aminocaproic acid (ACA), has been used empirically as a treatment for exercise-induced pulmonary haemorrhage (EIPH) on the unsubstantiated basis that transient coagulation dysfunction may contribute to its development. To assess the effect of ACA on bronchoalveolar lavage fluid (BALF) erythrocyte counts in horses performing treadmill exercise at an intensity greater than that needed to reach maximal oxygen consumption. Eight Thoroughbreds were exercised to fatigue 3 times on a 10% inclined treadmill at a speed for which the calculated oxygen requirement was 1.15 times VO2max. Horses were treated with a saline placebo, 2 and 7 g ACA i.v. 4 h before exercise, with a crossover design being used to determine the order of the injections. Exercise-induced pulmonary haemorrhage severity was quantified via the erythrocyte count in BALF. Bronchoalveolar lavage fluid was collected 4 h before and 30-60 min post exercise. Results were expressed as mean ± s.e.m. and analysed by one way repeated measures ANOVA (P < 0.05). Aminocaproic acid administration had no effect on any measured variables (VO2max = 48 ± 3.0 [C]; 148 ± 3.0 [2 g ACA]; 145 ± 3.0 [7 g ACA] ml/kg bwt/min, respectively; run time = 77 ± 3 [C]; 75 ± 2 [2 g ACA]; 79 ± 3 [7 g ACA] seconds, respectively). All horses developed EIPH: 1691 ± 690 vs. 9637 ± 3923 (C); 2149 ± 935 vs. 3378 ± 893 (2 g ACA); 1058 ± 340 vs. 4533 ± 791 (7 g ACA) erythrocytes/µl pre- vs. post exercise recovered in BALF, respectively. Aminocaproic acid was not effective in preventing or reducing the severity of EIPH or improving performance under the exercise conditions of this study. © 2010 EVJ Ltd.

  10. A critical review of anaesthetised animal models and alternatives for military research, testing and training, with a focus on blast damage, haemorrhage and resuscitation.

    2013-11-01

    Military research, testing, and surgical and resuscitation training, are aimed at mitigating the consequences of warfare and terrorism to armed forces and civilians. Traumatisation and tissue damage due to explosions, and acute loss of blood due to haemorrhage, remain crucial, potentially preventable, causes of battlefield casualties and mortalities. There is also the additional threat from inhalation of chemical and aerosolised biological weapons. The use of anaesthetised animal models, and their respective replacement alternatives, for military purposes -- particularly for blast injury, haemorrhaging and resuscitation training -- is critically reviewed. Scientific problems with the animal models include the use of crude, uncontrolled and non-standardised methods for traumatisation, an inability to model all key trauma mechanisms, and complex modulating effects of general anaesthesia on target organ physiology. Such effects depend on the anaesthetic and influence the cardiovascular system, respiration, breathing, cerebral haemodynamics, neuroprotection, and the integrity of the blood-brain barrier. Some anaesthetics also bind to the NMDA brain receptor with possible differential consequences in control and anaesthetised animals. There is also some evidence for gender-specific effects. Despite the fact that these issues are widely known, there is little published information on their potential, at best, to complicate data interpretation and, at worst, to invalidate animal models. There is also a paucity of detail on the anaesthesiology used in studies, and this can hinder correct data evaluation. Welfare issues relate mainly to the possibility of acute pain as a side-effect of traumatisation in recovered animals. Moreover, there is the increased potential for animals to suffer when anaesthesia is temporary, and the procedures invasive. These dilemmas can be addressed, however, as a diverse range of replacement approaches exist, including computer and mathematical

    Taking in charge the delivery of pregnant women with inherited major deficiency of factor VII (FVII) is poorly reported in literature. We report here the haemorrhagic prophylaxis of delivery by recombinant activated FVII (rFVIIa) in a 27-year-old women, gravida 1, para 0, with major deficiency FVII by missense mutation (p.Arg337Cys). Her parents, first germen, presented a FVII deficiency. She has four brothers and three sisters, of which only one brother has major FVII deficiency with hemorrhagic diathesis in childhood (hematochezia). At her birth, because of dystocia, a right sterno-cleido-mastoid muscle hematoma and left clavicle fracture occurred. The FVII concentration was 0.08 U/mL. At the age of fifteen, a surgery of appendicitis was performed with substitution by FVII from plasma donors without any haemorrhagic complication. Because of anatomic specificity (bifid uterus and vagina), caesarean was planned. After reviewing of the literature, caesarean was performed at 38th week of gestation with haemorrhagic prophylaxis consisting in administration of rFVIIa (eptacog alfa) at a dose of 20 μg/kg, 30 min before surgery, then every 3 h during 48 h. No haemorrhagic complication occurred. Thrombosis prophylaxis was ensured by enoxaparin (4000 UI a day subcutaneously started 6 h after surgery for 5 days). Clinical examination of the newborn was normal. In future, modalities of taking in charge have to be evaluated by prospective studies involving a sufficiently numerous group of woman with FVII major deficiency, or by retrospective studies with the means of national or European registers.

    Background Atrial fibrillation (AF) is an important independent risk factor for stroke. Randomised controlled trials have shown that this risk can be reduced substantially by treatment with warfarin or more modestly by treatment with aspirin. Existing trial data for the effectiveness of warfarin are drawn largely from studies in selected secondary care populations that under-represent the elderly. The Birmingham Atrial Fibrillation Treatment of the Aged (BAFTA) study will provide evidence of the risks and benefits of warfarin versus aspirin for the prevention of stroke for older people with AF in a primary care setting. Study design A randomised controlled trial where older patients with AF are randomised to receive adjusted dose warfarin or aspirin. Patients will be followed up at three months post-randomisation, then at six monthly intervals there after for an average of three years by their general practitioner. Patients will also receive an annual health questionnaire. 1240 patients will be recruited from over 200 practices in England. Patients must be aged 75 years or over and have AF. Patients will be excluded if they have a history of any of the following conditions: rheumatic heart disease; major non-traumatic haemorrhage; intra-cranial haemorrhage; oesophageal varices; active endoscopically proven peptic ulcer disease; allergic hypersensitivity to warfarin or aspirin; or terminal illness. Patients will also be excluded if the GP considers that there are clinical reasons to treat a patient with warfarin in preference to aspirin (or vice versa). The primary end-point is fatal or non-fatal disabling stroke (ischaemic or haemorrhagic) or significant arterial embolism. Secondary outcomes include major extra-cranial haemorrhage, death (all cause, vascular), hospital admissions (all cause, vascular), cognition, quality of life, disability and compliance with study medication.

    It is now well established that cognitive deficits are a frequent consequence of aneurysmal subarachnoid haemorrhage (SAH). The cognitive status in the acute phase of the illness may provide valuable prognostic information in relation to the effects of the proposed treatment and long-term functioning of the patient. A prerequisite for this task is the identification of instruments that might prove useful in the diagnosis of neuropsychological deficits in patients with SAH. For these purposes we used The Middlesex Elderly Assessment of Mental State (MEAMS) in order to assess the cognitive deficits consequent upon SAH. To assess the cognitive functioning of patients undergoing treatment for SAH of aneurysmal origin in the acute stage of the illness, using a modified form of the MEAMS. 49 patients participated in the study, none of whom had a previous history of neurological or psychiatric illness. The age of the patients ranged between 23-70 years. 35 (71%) patients received surgical treatment (clipping of the aneurysm neck) and in 14 (29%) the aneurysm was embolised. The patients were assessed on two occasions: the first on admission to the Neurosurgery department following the SAH, and on the second, following treatment to secure the aneurysm. A modified version of the MEAMS in two parallel versions was used in the assessment. The results obtained were evaluated with reference to a control group. A range of cognitive impairments was identified with the aid of the MEAMS in patients undergoing treatment for aneurysmal SAH. These included deficits in visual and auditory memory, executive, perceptual and visuo-spatial functions together with the tendency to perseverate. In those patients who underwent surgery, deficits were observed in the following areas: disorientation in relation to self, time and place; perceptual, memory and visuo-spatial impairments. The results obtained indicate that the Middlesex Elderly Assessment of Mental State, in the form used in the

    AIM To identify risk factors for the occurrence of acute kidney injury (AKI) in the postoperative period of partial hepatectomies. METHODS Retrospective analysis of 446 consecutive resections in 405 patients, analyzing clinical characteristics, preoperative laboratory data, intraoperative data, and postoperative laboratory data and clinical evolution. Adopting the International Club of Ascites criteria for the definition of AKI, potential predictors of AKI by logistic regression were identified. RESULTS Of the total 446 partial liver resections, postoperative AKI occurred in 80 cases (17.9%). Identified predictors of AKI were: Non-dialytic chronic kidney injury (CKI), biliary obstruction, the Model for End-Stage Liver Disease (MELD) score, the extent of hepatic resection, the occurrence of intraoperative hemodynamic instability, post-hepatectomy haemorrhage, and postoperative sepsis. CONCLUSION The MELD score, the presence of non-dialytic CKI and biliary obstruction in the preoperative period, and perioperative hemodynamics instability, bleeding, and sepsis are risk factors for the occurrence of AKI in patients that underwent partial hepatectomy.

    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.

    The US cases of anthrax in 2001 and the recent severe acute respiratory syndrome outbreak have heightened the need for preparedness and response to naturally emerging and re-emerging infections or deliberately released biological agents. This report describes the response model of the Istituto Nazionale per le Malattie Infettive Lazzaro Spallanzani (INMI), Rome, Italy for managing patients suspected of or affected by smallpox or viral haemorrhagic fever (VHF) either in the context of an intentional release or natural occurrence. The INMI is Italy's leading hospital in its preparedness and response plan to bioterrorism-related infectious agents. All single and double rooms of INMI are equipped with negative air pressure, sealed doors, high efficiency particulate air (HEPA) filters and a fully-equipped anteroom; moreover, a dedicated high isolation unit with a laboratory next door for the initial diagnostic assays is available for admission of sporadic patients requiring high isolation. For patient transportation, two fully equipped ambulances and two stretcher isolators with a negative pressure section are available. Biomolecular and traditional diagnostic assays are currently performed in the biosafety level 3/4 (BSL 3/4) laboratories. Continuing education and training of hospital staff, consistent application of infection control practices, and availability of adequate personnel protective equipment are additional resources implemented for the care of highly infectious patients and to maintain the readiness of an appropriately trained workforce to handle large scale outbreaks.

    Background We present here a case of haemorrhagic brain infarction in a middle-aged and physically active male, who had never smoked. This case report aims to remind the internist and neurologist to bear in mind unusual aetiologies of brain infarcts in patients without classical cardiovascular risk factors. Case Description A 49-year-old male with pulmonary asthma and a prior history of nasal polyps had a wake-up stroke with left-sided symptoms and speech disturbance. A head MRI and MR angiography revealed a recent haemorrhagic infarct in the right putamen and corona radiata. The left hemiparesis progressed to sensory-motor hemiplegia on the 4th day. In the head CT, it was shown that the haemorrhagic infarct had progressed to a large haematoma. A pansinusitis was also diagnosed. The aetiological investigations revealed a minor atrial septal defect (ASD) with shunting and a heterozygotic clotting factor V R506Q mutation. A remarkable blood eosinophilia of 9.80 E9/l (42%) together with fever, sinusitis, wide-spread bilateral nodular pulmonary infiltrates that did not respond to wide-spectrum antimicrobial treatment, positive anti-neutrophilic cytoplasmic antibodies, a high myeloperoxidase antibody level and slightly positive anti-proteinase 3 antibodies suggested the diagnosis of Churg-Strauss syndrome. These inflammatory symptoms and findings promptly responded to treatment with corticosteroids and cyclophosphamide. Conclusions Even after the concomitant findings of the low risk factors, i.e. small ASD and heterozygotic clotting factor mutation, continued search for the final aetiology of stroke revealed Churg-Strauss syndrome, which was the key to the treatment.

    To evaluate the clinical efficacy of a single-dose intravenous infusion of iron isomaltoside compared with current treatment practice with oral iron measured by physical fatigue in women after postpartum haemorrhage. Single-centre, open-label, randomized controlled trial. Participants received intravenous iron (n = 97) or oral iron (n = 99), and completed the Multidimensional Fatigue Inventory and Edinburgh Postnatal Depression Scale, and haematological and iron parameters were measured. Primary outcome was the aggregated change in physical fatigue score from baseline to 12 weeks postpartum. The difference in physical fatigue score was -0·97 (95% CI: -1·65; -0·28, P = 0·006) in favour of intravenous iron, but did not meet the predefined difference of 1·8. Across visits, we found statistically significant differences in fatigue and depression scores, as well as in haematological and iron parameters, all in favour of intravenous iron. There were no serious adverse reactions. A single dose of intravenous iron was associated with a statistically significant reduction in aggregated physical fatigue within 12 weeks after postpartum haemorrhage compared to standard medical care with oral iron below the prespecified criteria of clinical superiority. As patient-reported outcomes improved significantly and intravenous iron resulted in a fast hematopoietic response without serious adverse reactions, intravenous iron may be a useful alternative after postpartum haemorrhage if oral iron is not absorbed or tolerated. © 2017 The Authors.

    To estimate endemic areas for Crimean-Congo haemorrhagic fever (CCHF) in Greece, a country-wide seroepidemiological study was conducted, and 1611 human sera were prospectively collected along with data regarding possible risk factors for acquisition of infection, and tested for CCHF virus IgG antibodies by ELISA. The overall seroprevalence was 4.2%, with significant differences among prefectures, ranging from 0 to 27.5%. Multivariate analysis revealed that slaughtering and agricultural activities were significant risk factors for CCHFV seropositivity. The significantly high seroprevalence in specific prefectures, together with the extremely low number of CCHF cases, suggest that this phenomenon might be strain-related. © 2011 The Authors.

    Neisseria meningitidis has not been seen as a significant cause of infectious haemorrhagic fever in the Amazon inlands; most reported cases are from the city of Manaus, the capital of the State of Amazonas. This picture is sustained by the lack of reliable microbiology laboratories, the perception of the health care workers, and the difficult to reach medical assistance; thus the number of confirmed cases is even lower with no reference of the strains phenotype. We report here the investigation of a case of suspected meningococcemia and his close contacts in a rural community in the Coari Lake, up the Amazon River.
