    The drinking water infrastructure in the United States is ageing; extreme weather events place additional stress on water systems that can lead to interruptions in the delivery of safe drinking water. We investigated the association between household exposures to water service problems and acute gastrointestinal illness (AGI) and acute respiratory illness (ARI) in Alabama communities that experienced a freeze-related community-wide water emergency. Following the water emergency, investigators conducted a household survey. Logistic regression models were used to estimate adjusted prevalence ratios (aPR) and 95% confidence intervals (CI) for self-reported AGI and ARI by water exposures. AGI was higher in households that lost water service for ⩾7 days (aPR 2·4, 95% CI 1·1-5·2) and experienced low water pressure for ⩾7 days (aPR 3·6, 95% CI 1·4-9·0) compared to households that experienced normal service and pressure; prevalence of AGI increased with increasing duration of water service interruptions. Investments in the ageing drinking water infrastructure are needed to prevent future low-pressure events and to maintain uninterrupted access to the fundamental public health protection provided by safe water supplies. Households and communities need to increase their awareness of and preparedness for water emergencies to mitigate adverse health impacts. PMID:25608522

    Using epidemiologic time series analysis, we examine associations between three hydroclimatic variables (temperature, precipitation, and streamflow) and waterborne acute gastro-intestinal illness (AGI) in two communities in the province of British Columbia (BC), Canada. The communities were selected to represent the major hydroclimatic regimes that characterize BC: rainfall-dominated and snowfall dominated. Our results show that the number of monthly cases of AGI increased with increasing temperature, precipitation, and streamflow in the same month in the context of a rainfall-dominated regime, and with increasing streamflow in the previous month in the context of a snowfall-dominated regime. These results suggest that hydroclimatology plays a role in driving the occurrence and variability of AGI in these settings. Further, this study highlights that the nature and magnitude of the effects of hydroclimatic variability on AGI are different in the context of a snowfall-dominated regime versus a rainfall-dominated regimes. We conclude by proposing that the watershed may be an appropriate context for enhancing our understanding of the complex linkages between hydroclimatic variability and waterborne illness in the context of a changing climate.

    Full Text Available Background: The incidence of self-reported acute gastrointestinal illness (AGI in Rigolet, Nunatsiavut, and Iqaluit, Nunavut, is higher than reported elsewhere in Canada; as such, understanding AGI-related healthcare use is important for healthcare provision, public health practice and surveillance of AGI. Objectives: This study described symptoms, severity and duration of self-reported AGI in the general population and examined the incidence and factors associated with healthcare utilization for AGI in these 2 Inuit communities. Design: Cross-sectional survey data were analysed using multivariable exact logistic regression to examine factors associated with individuals’ self-reported healthcare and over-the-counter (OTC medication utilization related to AGI symptoms. Results: In Rigolet, few AGI cases used healthcare services [4.8% (95% CI=1.5–14.4%]; in Iqaluit, some cases used healthcare services [16.9% (95% CI=11.2–24.7%]. Missing traditional activities due to AGI (OR=3.8; 95% CI=1.18–12.4 and taking OTC medication for AGI symptoms (OR=3.8; 95% CI=1.2–15.1 were associated with increased odds of using healthcare services in Iqaluit. In both communities, AGI severity and secondary symptoms (extreme tiredness, headache, muscle pains, chills were significantly associated with increased odds of taking OTC medication. Conclusions: While rates of self-reported AGI were higher in Inuit communities compared to non-Inuit communities in Canada, there were lower rates of AGI-related healthcare use in Inuit communities compared to other regions in Canada. As such, the rates of healthcare use for a given disease can differ between Inuit and non-Inuit communities, and caution should be exercised in making comparisons between Inuit and non-Inuit health outcomes based solely on clinic records and healthcare use.

    Rising global temperatures and expected shifts in regional hydroclimatology in a changing climate are likely to influence the risk of infectious waterborne illness. This study examines the role of hydroclimatology as an underlying driver of the epidemiology of waterborne gastro-intestinal illness and contributes to our currently limited understanding of the possible ecosystem-mediated impacts of climate change on health. Using time-series regression analysis, we examine the associations between three hydroclimatic factors (monthly temperature, precipitation, and streamflow) and the monthly occurrence of AGI illness in two communities in the province of British Columbia, Canada. The two communities were selected as study sites to represent the dominant hydroclimatic regimes that characterize the province of BC: the rainfall-dominated hydroclimatic regime and snowmelt-dominated hydroclimatic regime Our results show that the number of monthly cases of AGI increased with increasing temperature, precipitation, and streamflow in the same month in the context of a rainfall-dominated regime and with increasing streamflow in the previous month in the context of a snowfall-dominated regime. These results suggest that hydroclimatic factors play a role in driving the occurrence and variability of AGI illness in this setting. Further, this study has highlighted that the nature and magnitude of the effects of hydroclimatic factors on waterborne illness vary across different hydroclimatic settings. We conclude that the watershed may be an appropriate context within which we can and should enhance our understanding of water-related climate change impacts on health. Examining the role of hydroclimatology as an underlying driver of the epidemiology of infectious disease is key to understanding of the possible ecosystem-mediated impacts of climate change on health and developing appropriate adaptation responses.

    Waterborne illness related to the consumption of contaminated or inadequately treated water is a global public health concern. Although the magnitude of drinking water-related illnesses in developed countries is lower than that observed in developing regions of the world, drinking water is still responsible for a proportion of all cases of acute gastrointestinal illness (AGI) in Canada. The estimated burden of endemic AGI in Canada is 20·5 million cases annually - this estimate accounts for under-reporting and under-diagnosis. About 4 million of these cases are domestically acquired and foodborne, yet the proportion of waterborne cases is unknown. There is evidence that individuals served by private systems and small community systems may be more at risk of waterborne illness than those served by municipal drinking water systems in Canada. However, little is known regarding the contribution of these systems to the overall drinking water-related AGI burden in Canada. Private water supplies serve an estimated 12% of the Canadian population, or ~4·1 million people. An estimated 1·4 million (4·1%) people in Canada are served by small groundwater (2·6%) and surface water (1·5%) supplies. The objective of this research is to estimate the number of AGI cases attributable to water consumption from these supplies in Canada using a quantitative microbial risk assessment (QMRA) approach. This provides a framework for others to develop burden of waterborne illness estimates for small water supplies. A multi-pathogen QMRA of Giardia, Cryptosporidium, Campylobacter, E. coli O157 and norovirus, chosen as index waterborne pathogens, for various source water and treatment combinations was performed. It is estimated that 103 230 AGI cases per year are due to the presence of these five pathogens in drinking water from private and small community water systems in Canada. In addition to providing a mechanism to assess the potential burden of AGI attributed to small systems and

  7. [Acute gastrointestinal bleeding].

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

    Full Text Available Abstract Background Increasing livestock density and animal manure spreading, along with climate factors such as heavy rainfall, may increase the risk of acute gastrointestinal illness (AGI. In this study we evaluated the association between farming activities, precipitation and AGI. Methods A cross-sectional telephone survey of randomly selected residents (n = 7006 of 54 rural municipalities in Quebec, Canada, was conducted between April 2007 and April 2008. AGI symptoms and several risk factors were investigated using a phone questionnaire. We calculated the monthly prevalence of AGI, and used multivariate logistic regression, adjusting for several demographic and risk factors, to evaluate the associations between AGI and both intensive farming activities and cumulative weekly precipitation. Cumulative precipitation over each week, from the first to sixth week prior to the onset of AGI, was analyzed to account for both the delayed effect of precipitation on AGI, and the incubation period of causal pathogens. Cumulative precipitation was treated as a four-category variable: high (≥90th percentile, moderate (50th to th percentile, low (10th to th percentile, and very low (th percentile precipitation. Results The overall monthly prevalence of AGI was 5.6% (95% CI 5.0%-6.1%, peaking in winter and spring, and in children 0-4 years old. Living in a territory with intensive farming was negatively associated with AGI: adjusted odds ratio (OR = 0.70 (95% CI 0.51-0.96. Compared to low precipitation periods, high precipitation periods in the fall (September, October, November increased the risk of AGI three weeks later (OR = 2.20; 95% CI 1.09-4.44 while very low precipitation periods in the summer (June, July, August increased the risk of AGI four weeks later (OR = 2.19; 95% CI 1.02-4.71. Further analysis supports the role of water source on the risk of AGI. Conclusions AGI poses a significant burden in Quebec rural municipalities with a peak in winter

    Microbial measures of water quality are predictors of gastrointestinal illness among swimmers in some settings but not in others. Little is known whether water quality measures predict illness among people who engage in popular water recreation activities such as paddling, rowing, fishing, or boating ("incidental contact water recreation"). We sought to evaluate indicator microbes, protozoan pathogens, and turbidity as predictors of gastrointestinal illness following incidental contact water recreation. A cohort study of incidental contact water recreation was conducted in the Chicago, USA area. Recreation took place on inland lakes, rivers, Lake Michigan, and an urban waterway heavily impacted by wastewater effluent. Water samples were analyzed for Escherichia coli, enterococci, somatic coliphages, F+ coliphages, Giardia spp. and Cryptosporidium spp. (oo)cysts, and for turbidity. Median enterococci concentrations were 71.0 and 199.8 colony forming units/100  mL at general use and effluent-dominated waters, respectively. Among 4694 study participants with complete covariate data, 193 (4.1%) developed gastrointestinal illness within three days of water recreation. In multivariable logistic regression analysis, water quality metrics did not predict gastrointestinal illness among water recreators. Several variables other than water quality were associated acute gastrointestinal illness. The odds of such illness was increased by approximately two-fold by the presence of a chronic gastrointestinal condition, water exposure to the face, and by approximately 50% among those who fished (as opposed to other incidental contact activities). The odds of illness were reduced by approximately 50% among individuals who frequently used a water body for recreation. Unlike studies of swimmers at wastewater-impacted beaches that observed associations between water quality and illness incidence, this study did not. Public health protections for incidental contact recreation might

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

  19. Gastrointestinal disorders of the critically ill. Systemic consequences of ileus.

    Madl, Christian; Druml, Wilfred

    2003-06-01

    Ileus refers to the partial or complete blockage of the small and/or large intestine either by functional (adynamic or paralytic ileus) or mechanical bowel obstruction. The diffuse gastrointestinal dysmotility during functional and mechanical ileus may result in intestinal dilatation, increased luminal pressure and gut wall ischaemia which may lead to increased intra-abdominal pressure (IAP). Any type of ileus may promote abdominal fluid sequestration with severe systemic hypovolaemia, intestinal bacterial overgrowth with the evolution of bacterial translocation and systemic invasive infections and inflammation of the intestinal wall with concomitant release of cytokines and the development of the systemic inflammatory response syndrome. The most serious complications of ileus are mediated by an increase in IAP. Intra-abdominal hypertension has been found in up to 20% of critically ill patients and may lead to a broad pattern of systemic consequences with multiple organ dysfunction, including cardiovascular, hepatic, pulmonary, renal and neurological function. The abdominal compartment syndrome is an emergency condition which is defined as elevation of IAP above 20 to 25 mmHg and the presence of systemic consequences. Therapeutic considerations include the maintenance of adequate hydration status, avoidance of drugs known to impair intestinal perfusion, stimulation of gastric and intestinal motility and various nutritional aspects. Colonic tube placement after decompressive colonoscopy may be effective in reducing intestinal dilatation. In the abdominal compartment syndrome the 'open abdominal approach' with decompressive laparotomy by opening the peritoneal cavity and temporary abdominal closure is the therapy of choice.

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

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

  2. Role of toll-like receptors in acute gastrointestinal radiation syndrome

    Ionizing radiation induces various disorders according to the radiation sensitivity of each organ. Acute gastrointestinal radiation syndrome is a serious illness that is caused by exposure of gastrointestinal tract to high amounts of ionizing radiation in radiation accidents or radiation therapy in cancer treatment. Although the pathological mechanism have been well studied in human and animals, no effective treatments have been developed to date. The Toll-like receptor (TLR) family is one of the best-characterized families of innate immune receptors, which induce innate immune response against pathogen infection. However, contrary to their protective function, recent studies have suggested that immune responses triggered by TLRs play deleterious roles by aggravating tissue inflammation in some inflammatory and autoimmune diseases. This review describes recent advancement of our understanding of acute gastrointestinal radiation syndrome and the contributions of TLR to its pathological mechanisms. (author)

  3. Nutritional demands in acute and chronic illness.

    Richardson, Rosemary A; Davidson, H Isobel M

    2003-11-01

    Common to both acute and chronic disease are disturbances in energy homeostasis, which are evidenced by quantitative and qualitative changes in dietary intake and increased energy expenditure. Negative energy balance results in loss of fat and lean tissue. The management of patients with metabolically-active disease appears to be simple; it would involve the provision of sufficient energy to promote tissue accretion. However, two fundamental issues serve to prevent nutritional demands in disease being met. The determination of appropriate energy requirements relies on predictive formulae. While equations have been developed for critically-ill populations, accurate energy prescribing in the acute setting is uncommon. Only 25-32% of the patients have energy intakes within 10% of their requirements. Clearly, the variation in energy expenditure has led to difficulties in accurately defining the energy needs of the individual. Second, the acute inflammatory response initiated by the host can have profound effects on ingestive behaviour, but this area is poorly understood by practising clinicians. For example, nutritional targets have been set for specific disease states, i.e. pancreatitis 105-147 kJ (25-35 kcal)/kg; chronic liver disease 147-168 kJ (35-40 kcal)/kg, but given the alterations in gut physiology that accompany the acute-phase response, targets are unlikely to be met. In cancer cachexia attenuation of the inflammatory response using eicosapentaenoic acid results in improved nutritional intake and status. This strategy poses an attractive proposition in the quest to define nutritional support as a clinically-effective treatment modality in other disorders. PMID:15018475

  6. Diagnostic accuracy of CT angiography in acute gastrointestinal bleeding

    Full text: The aim of the study was to carry out a systematic review determining the accuracy of CT angiography in the diagnosis of acute gastrointestinal bleeding. A search of published work in Medline and manual searching of reference lists of articles was conducted. Studies were included if they compared CT angiography to a reference standard of upper gastrointestinal endoscopy, colonoscopy, angiography or surgery in the diagnosis of acute gastrointestinal bleeding. Eight published studies evaluating 129 patients were included. Data were used to form 2x2 tables. Computed tomography angiography showed pooled sensitivity of 86% (95% confidence interval 78-92%) and specificity of 95% (95% confidence interval 76-100%), without showing significant heterogeneity (x2 = 3.5, P=0.6) and (x2 - 5.4, P = 0.6), respectively. Summary receiver operating characteristic analysis showed an area under the curve of 0.93. Computed tomography angiography is accurate in the diagnosis of acute gastrointestinal bleeding and can show the precise location and aetiology of bleeding, thereby directing further management. Strong recommendations for use of CT cannot be made from this review because of the methodological limitations and further large prospective studies are needed to define the role of CT in acute gastrointestinal bleeding.

    2016-06-01

    The existing animal models used for the simulation of acute gastrointestinal bleedings are usually non-survival models. We developed and evaluated a new porcine model (domestic pig, German Landrace) in which the animal remains alive and survives the artificial bleeding without any cardiovascular impairment. This consists of a bleeding catheter which is implanted into the stomach, then subcutaneously tunnelled from the abdomen to the neck where it is exteriorized and fixed with sutures. Using the injection of porcine blood, controllable and reproducible acute upper gastrointestinal bleeding can be simulated while maintaining normal gastrointestinal motility and physiology. Depending on the volume of blood applied through the gastric catheter, the bleeding intensity can be varied from traces of blood to a massive haemorrhage. This porcine model could be valuable, e.g. for testing the efficacy of new bleeding diagnostics in large animals before human use. PMID:26306615

  9. Lactobacillus fermentum (PCC® supplementation and gastrointestinal and respiratory-tract illness symptoms: a randomised control trial in athletes

    2011-04-01

    Full Text Available Abstract Background Probiotics purportedly reduce symptoms of gastrointestinal and upper respiratory-tract illness by modulating commensal microflora. Preventing and reducing symptoms of respiratory and gastrointestinal illness are the primary reason that dietary supplementation with probiotics are becoming increasingly popular with healthy active individuals. There is a paucity of data regarding the effectiveness of probiotics in this cohort. The aim of this study was to evaluate the effectiveness of a probiotic on faecal microbiology, self-reported illness symptoms and immunity in healthy well trained individuals. Methods Competitive cyclists (64 males and 35 females; age 35 ± 9 and 36 ± 9 y, VO2max 56 ± 6 and 52 ± 6 ml.kg-1.min-1, mean ± SD were randomised to either probiotic (minimum 1 × 109 Lactobacillus fermentum (PCC® per day or placebo treatment for 11 weeks in a double-blind, randomised, controlled trial. The outcome measures were faecal L. fermentum counts, self-reported symptoms of illness and serum cytokines. Results Lactobacillus numbers increased 7.7-fold (90% confidence limits 2.1- to 28-fold more in males on the probiotic, while there was an unclear 2.2-fold (0.2- to 18-fold increase in females taking the probiotic. The number and duration of mild gastrointestinal symptoms were ~2-fold greater in the probiotic group. However, there was a substantial 0.7 (0.2 to 1.2 of a scale step reduction in the severity of gastrointestinal illness at the mean training load in males, which became more pronounced as training load increased. The load (duration×severity of lower respiratory illness symptoms was less by a factor of 0.31 (99%CI; 0.07 to 0.96 in males taking the probiotic compared with placebo but increased by a factor of 2.2 (0.41 to 27 in females. Differences in use of cold and flu medication mirrored these symptoms. The observed effects on URTI had too much uncertainty for a decisive outcome. There were clear reductions in

    This study assesses risk factors for food-borne gastrointestinal illness indicated by diarrhoea and/or vomiting using 14-day recalls among children and young adults. The study was set in Isiolo, a rural town of Kenya, inhabited mainly by pastoralists of different ethnic groups. The preparation methods of milk at the household level were also investigated. The study was cross-sectional and involved 900 participants from randomly selected households. They were interviewed using a structured questionnaire. An unmatched nested case-control study was constructed by randomly selecting three controls for each case. Potential risk factors for gastrointestinal illness were analysed using both univariate and multivariate logistic regression models with random effect on ethnic groups. The study results showed that consumption of mutton, carrots, Irish potatoes, raw camel milk, boiled camel milk and fermented camel milk were important risk factors for diarrhoea and/or vomiting, whereas the consumption of boiled goat milk, boiled cow milk, spinach, washing of hands with soap and the presence of proper drainage system had protective effects (odds ratio milk market chain pose the greatest risks for symptoms of food-borne gastrointestinal illness.

  12. Acute syndrome of radiation: injuries to the gastrointestinal tract

    Acute syndrome of radiation: injuries to the gastrointestinal tract. Exposure to ionising radiation at medium to high doses results in the manifestation of mixed pathologies. Following the analysis of several radiation accidents it is clear that intestinal injury influences patient survival. However the appearance of the classically defined gastrointestinal syndrome is not always evident. Nevertheless injury to the gastrointestinal tract, in particular loss of barrier function, seems to play an important role in the development of Multiple Organ Failure such as reported in the recent accident at Tokai Mura. Ionising radiation overexposure results in changes in intestinal motility and nutrient, fluid and electrolyte absorption and secretion all which may contribute to the genesis of diarrhea. In addition to modified cellular transport properties for nutrients or electrolytes, important loss of epithelial cells is also a major contributing factor. Intestinal functions are controlled by many factors such as neurotransmitters, locally released mediators from endocrine cells or immunocompetent cells in addition to luminal agents. To date, treatment of radiation-induced gastrointestinal injury is mainly symptomatic. However treatments such as growth factors, anti-inflammatory cytokines as well as cellular transplantation remain to be validated in the radiation accident situation. (author)

    Full Text Available Objective: There is a lack of information about the prevalence of gastrointestinal illnesses in Australia. Current disease surveillance systems capture only a few pathogens. The aim of this study is to describe the epidemiology of infectious gastrointestinal illnesses in Sydney, Australia. Methods: A retrospective cross-sectional study of patients with gastrointestinal symptoms who visited tertiary public hospitals in Sydney was conducted between 2007 and 2010. Patients with diarrhoea or loose stools with an enteric pathogen detected were identified. Demographic, clinical and potential risk factor data were collected from their medical records. Measures of association, descriptive and inferential statistics were analysed. Results: In total, 1722 patients were included in this study. Campylobacter (22.0% and Clostridium difficile (19.2% were the most frequently detected pathogens. Stratified analysis showed that rotavirus (22.4%, norovirus (20.7% and adenovirus (18.1% mainly affected children under 5 years; older children (5–12 years were frequently infected with Campylobacter spp. (29.8% and non-typhoid Salmonella spp. (24.4%; infections with C. difficile increased with age. Campylobacter and non-typhoid Salmonella spp. showed increased incidence in summer months (December to February, while rotavirus infections peaked in the cooler months (June to November. Discussion: This study revealed that gastrointestinal illness remains a major public health issue in Sydney. Improvement of current disease surveillance and prevention and control measures are required. This study emphasizes the importance of laboratory diagnosis of enteric infections and the need for better clinical data collection to improve management of disease risk factors in the community.

    Gastrointestinal bleeding is a common medical emergency. Although endoscopic treatment is effective in controlling non-variceal upper gastrointestinal bleeding, in cases of persistent bleeding radiological or surgical interventions are required. Application of cyanoacrylate for treatment of difficult-to-arrest non-variceal upper gastrointestinal bleeding is poorly investigated. We describe patients in whom cyanoacrylate for acute non-variceal gastrointestinal bleeding was used to stop the ble...

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

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

  20. Transcatheter embolization for treatment of acute lower gastrointestinal bleeding

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

    Full Text Available This retrospective analysis studied the records of 564 consecutive patients admitted to Gastrointestinal Bleeding Unit of Riyadh Medical Complex with acute upper gastrointestinal bleeding over a 2-year period (May 1996-April 1998. The purpose of the study was to analyze the mortality with an aim to identify the risk factors affecting mortality in these patients. Majority of patients were men (82% and Saudis (54%. Their mean age was 52.46 + 17.8 years. Esophageal varices (45% were the main causes of bleeding followed by duodenal ulcers (24%. Overall mortality in this series was 15.8% (89 patients. Comorbid diseases were responsible for death in 68 (76% patients, whereas, bleeding was considered to be directly responsible for death in 21 (24% patients. On analysis of data from this study, old age (>60 years, systolic pressure < 90 mm Hg on admission, comorbid disease, variceal bleeding and Child′s grade C in patients with chronic liver disease were associated with adverse outcome.

  2. Managing the acutely ill adult with sickle cell disease.

    Brown, Marvelle

    Sickle cell disease (SCD) is an autosomal recessively inherited condition, affecting the structure of the haemoglobin. SCD is a long-term chronic condition which is manifested by periods of acute painful sickling crisis, known as vaso-occlusive crisis (VOC) and is the cause of 90% of sickle cell-related hospital admissions. SCD is one of the most common genetic conditions worldwide and in the UK there are approximately 12,500 people living with it (Streetly et al,1997; Howard et al, 2008), making it more common than cystic fibrosis, yet there still remains many challenges in managing these patients when they become acutely ill. Lack of awareness and understanding of the illness, concerns regarding addiction and limited attention to the psycho-social implications of the illness, leads to less than effective care for this patient group when they are hospitalized. The aims of this article are to outline the pathophysiology of SCD, identify the causes of VOC and discuss the key principles of nursing management for patients experiencing a VOC. PMID:22306637

    Full Text Available Acute kidney injury (AKI is an independent variable for poor outcome in critically ill patients. The pathophysiology of septic AKI is distinct from that of non-septic AKI. We studied the clinical profile and outcome of septic AKI since such data is sparse in Indian patients. In this single-center retrospective, observational, cohort study, septic AKI has been found with high incidence (31% and overall mortality was 52%. Age, number of non-renal organ failure, and APACHE II score were found as significant predictors of outcome in this population.

    the follow up period, six patients of the 79 clinically successful patients died due to disseminated coagulopathy or complications of their underlying diseases, and so the total mortality rate was 19% (18 of 97 patients). Postembolization complications such as bowel ischemia or infarction did not occur during the observation period. Superselective transarterial embolization is an effective therapy for treating acute gastrointestinal hemorrhage, and it has a high technical rate and clinical success rate, and a low complication rate.

  5. From data patterns to mechanistic models in acute critical illness.

    Aerts, Jean-Marie; Haddad, Wassim M; An, Gary; Vodovotz, Yoram

    2014-08-01

    The complexity of the physiologic and inflammatory response in acute critical illness has stymied the accurate diagnosis and development of therapies. The Society for Complex Acute Illness was formed a decade ago with the goal of leveraging multiple complex systems approaches to address this unmet need. Two main paths of development have characterized the society's approach: (i) data pattern analysis, either defining the diagnostic/prognostic utility of complexity metrics of physiologic signals or multivariate analyses of molecular and genetic data and (ii) mechanistic mathematical and computational modeling, all being performed with an explicit translational goal. Here, we summarize the progress to date on each of these approaches, along with pitfalls inherent in the use of each approach alone. We suggest that the next decade holds the potential to merge these approaches, connecting patient diagnosis to treatment via mechanism-based dynamical system modeling and feedback control and allowing extrapolation from physiologic signals to biomarkers to novel drug candidates. As a predicate example, we focus on the role of data-driven and mechanistic models in neuroscience and the impact that merging these modeling approaches can have on general anesthesia. PMID:24768566

  7. Systematic Review of the Relationship between Acute and Late Gastrointestinal Toxicity after Radiotherapy for Prostate Cancer

    Matthew Sean Peach

    2015-01-01

    Full Text Available A small but meaningful percentage of men who are treated with external beam radiation therapy for prostate cancer will develop late gastrointestinal toxicity. While numerous strategies to prevent gastrointestinal injury have been studied, clinical trials concentrating on late toxicity have been difficult to carry out. Identification of subjects at high risk for late gastrointestinal injury could allow toxicity prevention trials to be performed using reasonable sample sizes. Acute radiation therapy toxicity has been shown to predict late toxicity in several organ systems. Late toxicities may occur as a consequential effect of acute injury. In this systematic review of published reports, we found that late gastrointestinal toxicity following prostate radiotherapy seems to be statistically and potentially causally related to acute gastrointestinal morbidity as a consequential effect. We submit that acute gastrointestinal toxicity may be used to identify at-risk patients who may benefit from additional attention for medical interventions and close follow-up to prevent late toxicity. Acute gastrointestinal toxicity could also be explored as a surrogate endpoint for late effects in prospective trials.

  8. Mysterious outbreaks of gastrointestinal illness associated with burritos supplied through school lunch programs.

    From October 1997 through March 1998, three outbreaks of gastrointestinal illness among school children were linked to company A burritos. In September 1998, a similar outbreak occurred in three North Dakota schools following lunches that included company B burritos. We conducted an investigation to determine the source of the North Dakota outbreak, identify other similar outbreaks, characterize the illness, and gather evidence about the cause. The investigation included epidemiologic analyses, environmental investigation, and laboratory analyses. In North Dakota, a case was defined as nausea, headache, abdominal cramps, vomiting, or diarrhea after lunch on 16 September 1998. Case definitions varied in the other states. In North Dakota, 504 students and staff met the case definition; predominant symptoms were nausea (72%), headache (68%), abdominal cramps (54%), vomiting (24%), and diarrhea (16%). The median incubation period was 35 min and median duration of illness was 6 h. Eating burritos was significantly associated with illness (odds ratio, 2.6; 95% confidence interval, 1.6 to 4.2). We identified 16 outbreaks that occurred in seven states from October 1997 through October 1998, affecting more than 1,900 people who ate burritos from two unrelated companies. All tortillas were made with wheat flour, but the fillings differed, suggesting that tortillas contained the etiologic agent. Results of plant inspections, tracebacks, and laboratory investigations were unrevealing. More than two million pounds of burritos were recalled or held from distribution. The short incubation period, symptoms, and laboratory data suggest that these outbreaks were caused by an undetected toxin or an agent not previously associated with this clinical syndrome. Mass psychogenic illness is an unlikely explanation because of the large number of sites where outbreaks occurred over a short period, the similarity of symptoms, the common food item, the lack of publicity, and the link to only

    Transcatheter arterial embolization as treatment of upper nonvariceal gastrointestinal bleeding is increasingly being used after failed primary endoscopic treatment. The results after embolization have become better and surgery still has a high mortality. Embolization is a safe and effective...... procedure, but its use is has been limited because of relatively high rates of rebleeding and high mortality, both of which are associated with gastrointestinal bleeding and non-gastrointestinal related mortality causes. Transcatheter arterial embolization is a valuable minimal invasive method in the...

  11. Copeptin for risk stratification in acute illness: beyond cardiological problems

    Roberto Cemin

    2013-10-01

    Full Text Available Copeptin (Cop has been recently proposed as a reliable marker for the diagnosis of acute coronary syndrome, altough its concentration was found to increase in a variety of other severe clinical conditions. The aim of the present study was to assess the utility of Cop to identify high-risk patients in the emergency room (ER. Eighty-five patients admitted to ER of the San Maurizio Regional Hospital of Bolzano between February to March 2010 with epigastric or chest pain and/or discomfort were included in the study. Blood was drawn at admission and sampled for Cop in standard laboratory tests. Cop levels were significantly higher in patients who died at the hospital or shortly afterwards as compared with survivors (median 61 vs 40.6 pmol/L; P=0.014. Cop levels were also higher in patients with severe health problems (62.9 vs 28.3 pmol/L; P<0.0001. The area under the receiver-operating characteristic curve of Cop was 0.70 for in-hospital death [95% confidence interval (CI 0.53-0.86], 0.74 for acute and subacute death (95% CI 0.61-0.87 and 0.90 for prediction of severe acute illness (95% CI 0.84-0.97. Accordingly, a Cop level >33.1 pmol/L correctly identified in-hospital death with 71% sensitivity and 74% specificity. A Cop level >13.6 pmol/L was instead associated with 89% sensitivity and 80% specificity for identifying patients with acute and severe conditions. The results of our analysis would suggest that the use of Cop may be a valuable aid in the ER for identifying patients with life-threatening conditions.

  12. An assessment tool for acutely ill medical patients.

    2012-01-26

    This article reports the implementation and impact of a standardized systematic evidence-based predictive score for the initial assessment of acutely ill medical patients. The Simple Clinical Score (SCS) was introduced in the A&E department and the medical floor of the authors\\' hospital between June 2007 and July 2008. The SCS was well received by the staff - 67% felt it greatly improved patient assessment and was very valuable for ensuring appropriate placement of the patient after admission and improved the quality of care. This article describes the change process, the pilot evaluation and the training programme undertaken during the implementation of the SCS. It is hoped that this experience will be of value to other project teams who are undertaking similar initiatives.

  14. Acute kidney injury in critically ill cancer patients: an update.

    Lameire, Norbert; Vanholder, Raymond; Van Biesen, Wim; Benoit, Dominique

    2016-01-01

    Patients with cancer represent a growing group among actual ICU admissions (up to 20 %). Due to their increased susceptibility to infectious and noninfectious complications related to the underlying cancer itself or its treatment, these patients frequently develop acute kidney injury (AKI). A wide variety of definitions for AKI are still used in the cancer literature, despite existing guidelines on definitions and staging of AKI. Alternative diagnostic investigations such as Cystatin C and urinary biomarkers are discussed briefly. This review summarizes the literature between 2010 and 2015 on epidemiology and prognosis of AKI in this population. Overall, the causes of AKI in the setting of malignancy are similar to those in other clinical settings, including preexisting chronic kidney disease. In addition, nephrotoxicity induced by the anticancer treatments including the more recently introduced targeted therapies is increasingly observed. However, data are sometimes difficult to interpret because they are often presented from the oncological rather than from the nephrological point of view. Because the development of the acute tumor lysis syndrome is one of the major causes of AKI in patients with a high tumor burden or a high cell turnover, the diagnosis, risk factors, and preventive measures of the syndrome will be discussed. Finally, we will briefly discuss renal replacement therapy modalities and the emergence of chronic kidney disease in the growing subgroup of critically ill post-AKI survivors. PMID:27480256

  16. The Use of Acute Peritoneal Dialysis in Critically Ill Newborns.

    Ustyol, Lokman; Peker, Erdal; Demir, Nihat; Agengin, Kemal; Tuncer, Oguz

    2016-01-01

    BACKGROUND To evaluate the efficacy, complications, and mortality rate of acute peritoneal dialysis (APD) in critically ill newborns. MATERIAL AND METHODS The study included 31 newborns treated in our center between May 2012 and December 2014. RESULTS The mean birth weight, duration of peritoneal dialysis, and gestational age of the patients were determined as 2155.2±032.2 g (580-3900 g), 4 days (1-20 days), and 34 weeks (24-40 weeks), respectively. The main reasons for APD were sepsis (35.5%), postoperative cardiac surgery (16%), hypoxic ischemic encephalopathy (13%), salting of the newborn (9.7%), congenital metabolic disorders (6.1%), congenital renal diseases (6.5%), nonimmune hydrops fetalis (6.5%), and acute kidney injury (AKI) due to severe dehydration (3.2%). APD-related complications were observed in 48.4% of the patients. The complications encountered were catheter leakages in nine patients, catheter obstruction in three patients, peritonitis in two patients, and intestinal perforation in one patient. The general mortality rate was 54.8%, however, the mortality rate in premature newborns was 81.3%. CONCLUSIONS APD can be an effective, simple, safe, and important therapy for renal replacement in many neonatal diseases and it can be an appropriate treatment, where necessary, for newborns. Although it may cause some complications, they are not common. However, it should be used carefully, especially in premature newborns who are vulnerable and have a high mortality risk. The recommendation of APD therapy in such cases needs to be verified by further studies in larger patient populations. PMID:27121012

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

  20. The absence of exanthema is related with death and illness severity in acute enterovirus infection

    2014-11-01

    Conclusions: A considerable proportion of children with an acute enterovirus infection in Guangdong Province, China during 2009–2012 presented no exanthema, and the absence of exanthema was found to be related to death and illness severity for these acute enterovirus infections. Clinicians in China should consider enterovirus as the possible pathogen when treating children with an acute pathogen infection without exanthema.

  1. Investigation on the clinical practice of transcatheter embolization for acute gastrointestinal hemorrhage

    Objective: To study the tactics, methods and relevant factors of transcatheter embolization for acute gastrointestinal hemorrhage. Methods: Fifteen patients with acute gastrointestinal hemorrhage were embolized by one of the methods of Polyvinyl Alcohol (PVA), gelfoam or metal coils. Four of the fifteen patients were upper gastrointestinal hemorrhage, the other cases were lower gastrointestinal hemorrhage which were embolized using coaxial microcatheter. Results: Fourteen of the fifteen patients were treated successfully by these methods. There were total 17 times of embolization for 16 parts, the success rate reached 94. 1%. The other one revealed an infarction of intestine after the embolization and was cured by resection. One of the fifteen patients appeared a recurrent hemorrhage 3 months later, and confirmed to be a hemangiolymphangioma. Two patients with malignant tumor were operated upon selectively. The other patient of intestinal hemorrhage was embolized successfully by using a metal coil after shock. Leiomyoma complicated with large area of bleeding was finally proven by operation. Conclusions: Transcatheter embolization for acute massive gastrointestinal hemorrhage is safe and efficient under different choice of methods. The key of success is the right selection of embolized target artery and dosage of emboli

  4. Flooding and emergency room visits for gastrointestinal illness in Massachusetts: a case-crossover study.

    Timothy J Wade

    Full Text Available INTRODUCTION: Floods and other severe weather events are anticipated to increase as a result of global climate change. Floods can lead to outbreaks of gastroenteritis and other infectious diseases due to disruption of sewage and water infrastructure and impacts on sanitation and hygiene. Floods have also been indirectly associated with outbreaks through population displacement and crowding. METHODS: We conducted a case-crossover study to investigate the association between flooding and emergency room visits for gastrointestinal illness (ER-GI in Massachusetts for the years 2003 through 2007. We obtained ER-GI visits from the State of Massachusetts and records of floods from the National Oceanic and Atmospheric Association's Storm Events Database. ER-GI visits were considered exposed if a flood occurred in the town of residence within three hazard periods of the visit: 0-4 days; 5-9 days; and 10-14 days. A time-stratified bi-directional design was used for control selection, matching on day of the week with two weeks lead or lag time from the ER-GI visit. Fixed effect logistic regression models were used to estimate the risk of ER-GI visits following the flood. RESULTS AND CONCLUSIONS: A total of 270,457 ER-GI visits and 129 floods occurred in Massachusetts over the study period. Across all counties, flooding was associated with an increased risk for ER-GI in the 0-4 day period after flooding (Odds Ratio: 1.08; 95% Confidence Interval: 1.03-1.12; but not the 5-9 days (Odds Ratio: 0.995; 95% Confidence Interval: 0.955-1.04 or the 10-14 days after (Odds Ratio: 0.966, 95% Confidence Interval: 0.927-1.01. Similar results were observed for different definitions of ER-GI. The effect differed across counties, suggesting local differences in the risk and impact of flooding. Statewide, across the study period, an estimated 7% of ER-GI visits in the 0-4 days after a flood event were attributable to flooding.

    Full Text Available Abstract Background Human bocavirus (HBoV is a newly discovered parvovirus associated with acute respiratory tract illness (ARTI and gastrointestinal illness. Our study is the first to analyze the characteristics of HBoV-positive samples from ARTI patients with a wide age distribution from Guangzhou, southern China. Methods Throat swabs (n=2811 were collected and analyzed from children and adults with ARTI over a 13-month period. The HBoV complete genome from a 60 year-old female patient isolate was also determined. Results HBoV DNA was detected in 65/2811 (2.3% samples, of which 61/1797 were from children (Mycoplasma pneumoniae had the highest frequency of 16.9% (11/65. Upper and lower respiratory tract illness were common symptoms, with 19/65 (29.2% patients diagnosed with pneumonia by chest radiography. All four adult patients had systemic influenza-like symptoms. Phylogenetic analysis of the complete genome revealed a close relationship with other HBoVs, and a more distant relationship with HBoV2 and HBoV3. Conclusions HBoV was detected from children and adults with ARTI from Guangzhou, southern China. Elderly people were also susceptive to HBoV. A single lineage of HBoV was detected among a wide age distribution of patients with ARTI.

    Extreme rainfall events may cause pluvial flooding, increasing the transmission of several waterborne pathogens. However, the risk of experiencing clinically overt infections following exposure to pluvial floodwater is poorly estimated. A retrospective cross-sectional survey was performed to quantify the occurrence of self-reported gastrointestinal, influenza-like illness (ILI) and dermatological complaints, and the frequency of visits to the general practitioner (GP), during a 4-week observation period following pluvial flooding at seven locations in The Netherlands. Questionnaires were sent to 817 flooded households, 149 (17%) of which returned the questionnaire reporting information for 199 participants. Contact with floodwater was significantly associated with increased occurrence of gastrointestinal [odds ratio (OR 4·44)], ILI (OR 2·75) and dermatological (OR 6·67) complaints, and GP visits (OR 2·72). Having hand contact with floodwater was associated with gastrointestinal and dermatological complaints, whereas ILI complaints were associated with being engaged in post-flooding cleaning operations and having walked/cycled through floodwater. This study shows that floodwater-associated diseases occur in urban settings following extreme rainfall events in a high-income country. As pluvial floods are expected to escalate in the future due to global climate change, further research is warranted to determine the disease burden of pluvial flooding and to assess the effect of different interventions, including raising awareness among stakeholders.

    2010-08-15

    To evaluate the results of emergency embolisation in acute arterial bleeding of the gastrointestinal tract with a liquid polyvinyl alcohol copolymer from two centres. We retrospectively analysed 16 cases (15 patients) of acute arterial bleeding of the gastrointestinal tract where emergency embolotherapy was performed by using the copolymer when acute haemorrhage was not treatable with endoscopic techniques alone. Cause of haemorrhage and technical and clinical success were documented. Arterial embolotherapy was successful in all 16 cases. The technical success rate was 100%. The cause of bleeding was pancreatitis in four, graft-versus-host disease (GVHD) of the colon in three, malignancy in three, angiodysplasia in two, ulcer in two and panarteritis no dosa and trauma in one each. There were no procedure-related complications. No bowel necrosis occurred because of embolisation. In 13 cases, the patients were discharged in good condition (81%); the three patients with GVHD died because of the underlying disease. The copolymer seems to have great potential in embolotherapy of acute arterial gastrointestinal bleeding. In our series none of the patients had rebleeding at the site of embolisation and no clinically obvious bowel necrosis occurred. (orig.)

  13. The role of nuclear medicine in acute gastrointestinal bleeding

    Robinson, P. (Saint James' s Hospital, Leeds (United Kingdom). Dept. of Radiology)

    1993-10-01

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

  14. Embolization of the Vasa Recta in Acute Lower Gastrointestinal Hemorrhage: A Report of Five Cases

    Purpose: To present our preliminary experience in embolization of the vasa recta in acute gastrointestinal hemorrhage. Methods: In four of five patients with acute gastrointestinal hemorrhage superselective embolization of the vasa recta was performed. In one patient in whom superselective catheterization of the bleeding vas rectum was technically impossible, the origin of this vessel was embolized at the level of the terminal arcade. The following embolization materials were used: microcoils and polyvinyl alcohol particles (355-500 μm), n= 2; microcoils only, n= 2; Gelfoam particles, n1. Results: Bleeding was found in two patients in the small bowel (jejunum and ileum) and in three patients in the colon. Immediate hemostasis was achieved in all patients. No signs of ischemia or infarction were observed after intervention. Conclusions: Superselective embolization of the vasa recta proved efficient and safe in our small patient group. Advantages of this technique are reduction of the embolized area to a minimum and direct control of hemostasis

Critically ill patients with acute kidney injury are at increased risk of venous thromboembolism and yet are often excluded...... from these trials. We hypothesized that for critically ill patients with acute kidney injury receiving continuous renal replacement therapy, a dose of 1 mg/kg enoxaparin subcutaneously once daily would improve thromboprophylaxis without increasing the risk of bleeding.

  16. The economic impact of the insured patients with severe chronic and acute illnesses: a qualitative approach

    Budi Aji

    2014-10-01

    Full Text Available Background: Little research has focused on the economic hardship among the insured with severe illnesses and high treatment costs, in particular, the consequence of poorer insurance coverage for high-cost illnesses. Therefore, we presented the case for identifying the experiences of insured patients with severe chronic and acute illnesses. This study identified a qualitative understanding of the economic impact of severe chronic and acute illnesses and household strategies to deal with high treatment costs. Design: Interviews were conducted with 19 insured households of three different health insurance programs with a family member that had been hospitalized for severe chronic or acute illnesses in either Banyumas or Margono Sukarjo hospitals in Banyumas, Central Java, Indonesia. A thematic analysis was applied to guide the interpretation of the data. Results: Insured households with a family member that had been hospitalized for severe chronic and acute illnesses were greatly affected by the high treatment costs. Four major issues emerged from this qualitative study: insured patients are still burdened with high out-of-pocket payments, households adopt various strategies to cope with the high cost of treatments, households experience financial hardships, and positive and negative perceptions of the insured regarding their health insurance coverage for acute and chronic illnesses. Conclusions: Askes and Jamsostek patients faced financial burdens from high cost sharing for hospital amenities, non-covered drugs, and treatments and other indirect costs. Meanwhile, Jamkesmas beneficiaries faced no financial burden for related medical services but were rather burdened with indirect costs for the carers. Households relied on internal resources to cover hospital bills as the first strategy, which included the mobilization of savings, sale of assets, and borrowing of money. External support was tapped secondarily and included financial support from

    2007-06-15

    This study was conducted to determine the ability of multi-detector-row computed tomography (CT) to identify the source and etiology of acute gastrointestinal bleeding. Eighteen patients with acute upper (n = 10) and lower (n = 8) gastrointestinal bleeding underwent 4-detector-row CT (n = 6), 16-detector-row CT (n = 11), and 64-slice CT (n = 1) with an arterial and portal venous phase of contrast enhancement. Unenhanced scans were performed in nine patients. CT scans were reviewed to determine conspicuity of bleeding source, underlying etiology, and for potential causes of false-negative prospective interpretations. Bleeding sources were prospectively identified with CT in 15 (83%) patients, and three (17%) bleeding sources were visualized in retrospect, allowing the characterization of all sources of bleeding with CT. Contrast extravasation was demonstrated with CT in all 11 patients with severe bleeding, but only in 1 of 7 patients with mild bleeding. The etiology could not be identified on unenhanced CT scans in any patient, whereas arterial-phase and portal venous-phase CT depicted etiology in 15 (83%) patients. Underlying etiology was correctly identified in all eight patients with mild GI bleeding. Multi-detector-row CT enables the identification of bleeding source and precise etiology in patients with acute gastrointestinal bleeding. (orig.)

  1. Diminishing willingness to pay per quality-adjusted life year: valuing acute foodborne illness.

    Haninger, Kevin; Hammitt, James K

    2011-09-01

    We design and conduct a stated-preference survey to estimate willingness to pay (WTP) to reduce foodborne risk of acute illness and to test whether WTP is proportional to the corresponding gain in expected quality-adjusted life years (QALYs). If QALYs measure utility for health, then economic theory requires WTP to be nearly proportional to changes in both health quality and duration of illness and WTP could be estimated by multiplying the expected change in QALYs by an appropriate monetary value. WTP is elicited using double-bounded, dichotomous-choice questions in which respondents (randomly selected from the U.S. general adult population, n = 2,858) decide whether to purchase a more expensive food to reduce the risk of foodborne illness. Health risks vary by baseline probability of illness, reduction in probability, duration and severity of illness, and conditional probability of mortality. The expected gain in QALYs is calculated using respondent-assessed decrements in health-related quality of life if ill combined with the duration of illness and reduction in probability specified in the survey. We find sharply diminishing marginal WTP for severity and duration of illness prevented. Our results suggest that individuals do not have a constant rate of WTP per QALY, which implies that WTP cannot be accurately estimated by multiplying the change in QALYs by an appropriate monetary value.

  3. New Insight for the Diagnosis of Gastrointestinal Acute Graft-versus-Host Disease

    Florent Malard

    2014-01-01

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

  4. Can nutrition support interfere with recovery from acute critical illness?

    Schulman, Rifka C; Mechanick, Jeffrey I

    2013-01-01

    Malnutrition, following critical illness-related metabolic and immune neuroendocrine derangements, is exacerbated by energy and protein deficits beginning early in the intensive care unit (ICU) stay. While nutrition support is an important component of ICU care, adverse effects can occur. Underfeeding, due to insufficient energy and/or protein is associated with poor patient outcomes. Overfeeding carbohydrates, lipids, and/or protein can result in hyperglycemia, hypertriglyceridemia, hepatic dysfunction, and/or azotemia. Individualization of the nutritional prescription with clinical monitoring and repeated adjustment is necessary to avoid harm. Appropriate use of tight glycemic control protocols in combination with nutrition support can prevent hyperglycemia, while minimizing glycemic variability and hypoglycemic events. While the enteral route is favored for nutrition support, early supplemental parenteral nutrition should be considered in selected high-risk patients. Thus, risk stratification of patients upon admission to the ICU can be helpful to design individualized nutritional prescriptions maximizing benefit while avoiding potential interference with recovery.

  5. Gastrointestinal ischemia monitoring through impedance spectroscopy as a tool for the management of the critically ill.

    Beltran, Nohra E; Sacristan, Emilio

    2015-07-01

    Impedance spectroscopy (IS) has been proposed as a tool for monitoring mucosal tissue ischemia and damage in the gut of critically ill patients resulting from shock and hypoperfusion. A specific device and system have been developed and tested for this specific application over the past 12 years by our research group. This paper reviews previously published studies as well as unpublished experimental results, and puts the whole in context and perspective to help understand this technology. Results presented include summaries of gastric reactance measurement understanding, in vivo measurements in animal models, clinical significance of the measurement, and future perspectives of clinical use of this technology. All of the experimental work done to date has been designed to determine the evolving device prototypes' performance and limitations from an instrumentation point of view. Although there are still questions to be answered with regard to the IS measurement, we conclude that we have reached enough confidence in the measurement and the device's performance and safety to begin clinically oriented research to learn how this technology may be useful in the diagnosis and management of different populations of the critically ill.

    2016-01-01

    Delays in seeking appropriate healthcare can increase the case fatality of acute febrile illnesses, and circuitous routes of care-seeking can have a catastrophic financial impact upon patients in low-income settings. To investigate the relationship between poverty and pre-hospital delays for patients with acute febrile illnesses, we recruited a cross-sectional, convenience sample of 527 acutely ill adults and children aged over 6 months, with a documented fever ≥38.0°C and symptoms of up to 14 days’ duration, presenting to a tertiary referral hospital in Chittagong, Bangladesh, over the course of one year from September 2011 to September 2012. Participants were classified according to the socioeconomic status of their households, defined by the Oxford Poverty and Human Development Initiative’s multidimensional poverty index (MPI). 51% of participants were classified as multidimensionally poor (MPI>0.33). Median time from onset of any symptoms to arrival at hospital was 22 hours longer for MPI poor adults compared to non-poor adults (123 vs. 101 hours) rising to a difference of 26 hours with adjustment in a multivariate regression model (95% confidence interval 7 to 46 hours; P = 0.009). There was no difference in delays for children from poor and non-poor households (97 vs. 119 hours; P = 0.394). Case fatality was 5.9% vs. 0.8% in poor and non-poor individuals respectively (P = 0.001)—5.1% vs. 0.0% for poor and non-poor adults (P = 0.010) and 6.4% vs. 1.8% for poor and non-poor children (P = 0.083). Deaths were attributed to central nervous system infection (11), malaria (3), urinary tract infection (2), gastrointestinal infection (1) and undifferentiated sepsis (1). Both poor and non-poor households relied predominantly upon the (often informal) private sector for medical advice before reaching the referral hospital, but MPI poor participants were less likely to have consulted a qualified doctor. Poor participants were more likely to attribute delays in

  8. The diagnosis and management of acute childhood illness: is there a role for health visitors?

    Kendrick, D; Young, A; Futers, D

    2000-12-01

    Much of the published literature on nurse practitioners relates to nurses with backgrounds, training and nursing experience other than health visiting. Health visitors however may be ideally placed to develop their role in the identification and management of acute childhood illness, and such a development may benefit patients, the health service and health visitors themselves. This study examines the current practice and attitudes of heath visitors in identifying and managing acute childhood illness using a postal questionnaire survey in one community National Health Service (NHS) Trust. The majority of responding health visitors reported that they were already identifying and advising on a range of acute childhood illnesses. Their confidence in undertaking these activities varied by condition. They were less confident in identifying and advising on conditions requiring the use of diagnostic equipment, viral illnesses which are becoming increasingly rare, and those with potentially serious outcomes. More knowledge and more training were seen as methods for increasing confidence. Most health visitors could see advantages in taking on this role; almost two thirds felt it would become part of the role of the health visitor in the future and a high level of interest was expressed in developing such a role.

  9. Mobilization of xanthine oxidase from the gastrointestinal tract in acute pancreatitis

    Closa Daniel

    2004-01-01

    Full Text Available Abstract Background Xanthine oxidoreductase has been proposed to play a role in the development of local and systemic effects of acute pancreatitis. Under physiologic conditions, the enzyme exists mainly as xanthine dehydrogenase (XDH but can be converted by proteolytic cleavage to its superoxide-generating form xanthine oxidase (XOD. In addition to its intracellular location XDH/XOD is also associated to the polysaccharide chains of proteoglycans on the external endothelial cell membrane. In the early stages of acute pancreatitis, this enzyme seems to be arising from its mobilization from the gastrointestinal endothelial cell surface. Taking into account the ability of α-amylase to hydrolyze the internal α-1,4 linkages of polysaccharides, we wanted to elucidate the involvement of α-amylase in XDH/XOD mobilization from the gastrointestinal endothelial cell surface and the relevance of the ascitic fluid (AF as the source of α-amylase in experimental acute pancreatitis. Methods Acute pancreatitis was induced in male Wistar rats by intraductal administration of 5% sodium taurocholate. In another experimental group 3000 U/Kg α-amylase was i.v. administered. The concentrations of XDH, XOD and α-amylase in plasma and AF and myeloperoxidase (MPO in lung have been evaluated. In additional experiments, the effect of peritoneal lavage and the absorption of α-amylase present in the AF by an isolated intestine have been determined. Results Similar increase in XDH+XOD activity in plasma was observed after induction of acute pancreatitis and after i.v. administration of α-amylase. Nevertheless, the conversion from XDH to XOD was only observed in the pancreatitis group. Lung inflammation measured as MPO activity was observed only in the pancreatitis group. In addition peritoneal lavage prevented the increase in α-amylase and XDH+XOD in plasma after induction of pancreatitis. Finally, it was observed that α-amylase is absorbed from the AF by the

    2015-01-01

    Hospitalists and others acute care providers are limited by gaps in evidence addressing the needs of the acutely ill older adult population. The Society of Hospital Medicine (SHM) sponsored the Acute Care of Older Patients (ACOP) Priority Setting Partnership to develop a research agenda focused on bridging this gap. Informed by the Patient-Centered Outcomes Research Institute (PCORI) framework for identification and prioritization of research areas, we adapted a methodology developed by the James Lind Alliance to engage diverse stakeholders in the research agenda setting process. The work of the Partnership proceeded through four steps: convening, consulting, collating, and prioritizing. First, the steering committee convened a Partnership of 18 stakeholder organizations in May 2013. Next, stakeholder organizations surveyed members to identify important unanswered questions in the acute care of older persons, receiving 1299 responses from 580 individuals. Finally, an extensive and structured process of collation and prioritization resulted in a final list of ten research questions in the following areas: advanced care planning, care transitions, delirium, dementia, depression, medications, models of care, physical function, surgery, and training. With the changing demographics of the hospitalized population, a workforce with limited geriatrics training, and gaps in evidence to inform clinical decision-making for acutely ill older patients, the identified research questions deserve the highest priority in directing future research efforts to improve care for the older hospitalized patient and enrich training.

  12. Spontaneous Perforation of Pyometra Presenting as Acute Abdomen and Pneumoperitoneum Mimicking Those of Gastrointestinal Origin

    Takahiro Yamada

    2015-01-01

    Full Text Available Gastrointestinal (GI perforation accounts for over 90% of acute abdomen and pneumoperitoneum. The presence of pneumoperitoneum secondary to spontaneously perforated pyometra is an interesting yet confusing finding given the absence of gastrointestinal (GI perforation, because pyometra is more common in postmenopausal women. We report an instructive case of diffuse peritonitis caused by spontaneous perforation of pyometra. A 70-year-old postmenopausal female was admitted to surgical emergency with signs of diffuse peritonitis. After resuscitation, an emergency laparotomy was performed because of suspicion of GI perforation. At laparotomy, about 2,000 mL of purulent fluid was found to be present in peritoneal cavity, while GI tract was intact. A rent with a diameter of 5 mm was found on anterior fundus of uterus. A total abdominal hysterectomy with a bilateral salpingo-oophorectomy was performed. Despite intensive care and a course of antibiotics, the patient died of multiple organ failure resulting from sepsis on postoperative day 16. Our case illustrates the importance of clinical knowledge of acute gynecological diseases, which are not uncommonly encountered by the general surgeon. Moreover, good appreciation of pelvic anatomy and close collaboration with gynecology and GI surgery colleagues is essential as operative intervention is often required.

    Cabezos, Pablo Antonio; Vera, Gema; Castillo, Mónica; Fernández-Pujol, Ramón; Martín, María Isabel; Abalo, Raquel

    2008-08-18

    Nausea and vomiting are amongst the most severe dose-limiting side effects of chemotherapy. Emetogenic activity in rats can only be evaluated by indirect markers, such as pica (kaolin intake), or delay in gastric emptying. The aim of this work was to study, by radiological methods, the alterations in gastrointestinal motility induced by acute cisplatin in the rat, and to compare them with the development of pica. Rats received cisplatin (0-6 mg kg(-1)) at day 0. In the pica study, individual food ingestion and kaolin intake were measured each day (from day -3 to day 3). In the radiological study, conscious rats received an intragastric dose of medium contrast 0, 24 or 48 h after cisplatin injection, and serial X-rays were taken 0-24 h after contrast. Cisplatin dose-dependently induced both gastric stasis and stomach distension, showing a strict temporal relationship with the induction of both acute and delayed pica. Radiological methods, which are non-invasive and preserve animals' welfare, are useful to study the effect of emetogenic drugs in the different gastrointestinal regions and might speed up the search for new anti-emetics.

    2012-05-01

    Full Text Available Abstract Background This is the first study to describe the geographical and temporal distribution of notifiable gastrointestinal illness (NGI in the Northwest Territories (NWT, Canada. Understanding the distribution of NGI in space and time is important for identifying communities at high risk. Using data derived from the Northwest Territories Communicable Disease Registry (NWT CDR, a number of spatial and temporal techniques were used to explore and analyze NGI incidence from the years 1991 to 2008. Relative risk mapping was used to investigate the variation of disease risk. Scan test statistics were applied to conduct cluster identification in space, time and space-time. Seasonal decomposition of the time series was used to assess seasonal variation and trends in the data. Results There was geographic variability in the rates of NGI with higher notifications in the south compared to the north. Incidence of NGI exhibited seasonality with peaks in the fall months for most years. Two possible outbreaks were detected in the fall of 1995 and 2001, of which one coincided with a previously recognized outbreak. Overall, incidence of NGI fluctuated from 1991 to 2001 followed by a tendency for rates to decrease from 2002 to 2008. Conclusions The distribution of NGI notifications varied widely according to geographic region, season and year. While the analyses highlighted a possible bias in the surveillance data, this information is beneficial for generating hypotheses about risk factors for infection.

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

    Background Epidemic severe leptospirosis was recognized in Nicaragua in 1995, but unrecognized epidemic and endemic disease remains unstudied. Methodology/Principal Findings To determine the burden of and risk factors associated with symptomatic leptospirosis in Nicaragua, we prospectively studied patients presenting with fever at a large teaching hospital. Epidemiologic and clinical features were systematically recorded, and paired sera tested by IgM-ELISA to identify patients with probable and possible acute leptospirosis. Microscopic Agglutination Test and PCR were used to confirm acute leptospirosis. Among 704 patients with paired sera tested by MAT, 44 had acute leptospirosis. Patients with acute leptospirosis were more likely to present during rainy months and to report rural residence and fresh water exposure. The sensitivity of clinical impression and acute-phase IgM detected by ELISA were poor. Conclusions/Significance Leptospirosis is a common (6.3%) but unrecognized cause of acute febrile illness in Nicaragua. Rapid point-of-care tests to support early diagnosis and treatment as well as tests to support population-based studies to delineate the epidemiology, incidence, and clinical spectrum of leptospirosis, both ideally pathogen-based, are needed.

  2. Effect of diuretic use on 30-day postdialysis mortality in critically ill patients receiving acute dialysis.

    Vin-Cent Wu

    Full Text Available BACKGROUND: The impact of diuretic usage and dosage on the mortality of critically ill patients with acute kidney injury is still unclear. METHODS AND RESULTS: In this prospective, multicenter, observational study, 572 patients with postsurgical acute kidney injury receiving hemodialysis were recruited and followed daily. Thirty-day postdialysis mortality was analyzed using Cox's proportional hazards model with time-dependent covariates. The mean age of the 572 patients was 60.8±16.6 years. Patients with lower serum creatinine (p = 0.031 and blood lactate (p = 0.033 at ICU admission, lower predialysis urine output (p = 0.001 and PaO(2/FiO(2 (p = 0.039, as well as diabetes (p = 0.037 and heart failure (p = 0.049 were more likely to receive diuretics. A total of 280 (49.0% patients died within 30 days after acute dialysis initiation. The analysis of 30-day postdialysis mortality by fitting propensity score-adjusted Cox's proportional hazards models with time-dependent covariates showed that higher 3-day accumulated diuretic doses after dialysis initiation (HR = 1.449, p = 0.021 could increase the hazard rate of death. Moreover, higher time-varying 3-day accumulative diuretic doses were associated with hypotension (p<0.001 and less intense hemodialysis (p<0.001 during the acute dialysis period. BACKGROUND AND SIGNIFICANCE: Higher time-varying 3-day accumulative diuretic dose predicts mortality in postsurgical critically ill patients requiring acute dialysis. Higher diuretic doses are associated with hypotension and a lower intensity of dialysis. Caution should be employed before loop diuretics are administered to postsurgical patients during the acute dialysis period.

    Acute syndrome of radiation: injuries to the gastrointestinal tract. Exposure to ionising radiation at medium to high doses results in the manifestation of mixed pathologies. Following the analysis of several radiation accidents it is clear that intestinal injury influences patient survival. However the appearance of the classically defined gastrointestinal syndrome is not always evident. Nevertheless injury to the gastrointestinal tract, in particular loss of barrier function, seems to play an important role in the development of Multiple Organ Failure such as reported in the recent accident at Tokai Mura. Ionising radiation overexposure results in changes in intestinal motility and nutrient, fluid and electrolyte absorption and secretion all which may contribute to the genesis of diarrhea. In addition to modified cellular transport properties for nutrients or electrolytes, important loss of epithelial cells is also a major contributing factor. Intestinal functions are controlled by many factors such as neurotransmitters, locally released mediators from endocrine cells or immunocompetent cells in addition to luminal agents. To date, treatment of radiation-induced gastrointestinal injury is mainly symptomatic. However treatments such as growth factors, anti-inflammatory cytokines as well as cellular transplantation remain to be validated in the radiation accident situation. (author)

  4. The Feasibility of performing resistance exercise with acutely ill hospitalized older adults

    Rockwood Kenneth

    2003-10-01

    Full Text Available Abstract Background For older adults, hospitalization frequently results in deterioration of mobility and function. Nevertheless, there are little data about how older adults exercise in the hospital and definitive studies are not yet available to determine what type of physical activity will prevent hospital related decline. Strengthening exercise may prevent deconditioning and Pilates exercise, which focuses on proper body mechanics and posture, may promote safety. Methods A hospital-based resistance exercise program, which incorporates principles of resistance training and Pilates exercise, was developed and administered to intervention subjects to determine whether acutely-ill older patients can perform resistance exercise while in the hospital. Exercises were designed to be reproducible and easily performed in bed. The primary outcome measures were adherence and participation. Results Thirty-nine ill patients, recently admitted to an acute care hospital, who were over age 70 [mean age of 82.0 (SD= 7.3] and ambulatory prior to admission, were randomized to the resistance exercise group (19 or passive range of motion (ROM group (20. For the resistance exercise group, participation was 71% (p = 0.004 and adherence was 63% (p = 0.020. Participation and adherence for ROM exercises was 96% and 95%, respectively. Conclusion Using a standardized and simple exercise regimen, selected, ill, older adults in the hospital are able to comply with resistance exercise. Further studies are needed to determine if resistance exercise can prevent or treat hospital-related deterioration in mobility and function.

  5. Passive smoking, as measured by hair nicotine, and severity of acute lower respiratory illnesses among children

    Al-Delaimy WK

    2002-01-01

    Full Text Available Abstract The aim of this study was to describe the association between passive smoking and the severity of acute lower respiratory illnesses (ALRI among 351 children aged 3–27 months admitted to hospital. A total of 297 children provided hair samples, which were analysed for hair nicotine levels as an indicator of passive smoking. A severity of illness grading system was developed by using clinical and management criteria used by the medical staff at hospital. The OR for children with more severe illness being exposed to higher nicotine levels was 1.2, 95% CI: 0.57–2.58 when using dichotomised respiratory severity levels and upper versus lower nicotine quartile levels. In an ordinal logistic regression model, the OR of more severe illness being associated with higher nicotine levels was 1.07 (95% CI: 0.92–1.25. When analysis was limited to the more severe cases, the OR of the least severe category compared to the most severe category, in relation to nicotine levels in hair, was 1.79 (95% CI: 0.5–6.30. The ordinal logistic regression of this group of severely-ill children (OR 1.1 (95% CI: 0.94–1.29 was not substantially different from the overall study subjects. Conclusion In general, children with more severe illness tended to have higher levels of nicotine in their hair, although the results were within the limit of chance. Possible explanations of our results include environmental tobacco smoke (ETS being an initiator of ALRI rather than a risk to severity, exposure levels of ETS were too low to demonstrate an effect on severity, or the power of this study was not high enough to detect an association.

  6. The central role of hypothalamic inflammation in the acute illness response and cachexia.

    Burfeind, Kevin G; Michaelis, Katherine A; Marks, Daniel L

    2016-06-01

    When challenged with a variety of inflammatory threats, multiple systems across the body undergo physiological responses to promote defense and survival. The constellation of fever, anorexia, and fatigue is known as the acute illness response, and represents an adaptive behavioral and physiological reaction to stimuli such as infection. On the other end of the spectrum, cachexia is a deadly and clinically challenging syndrome involving anorexia, fatigue, and muscle wasting. Both of these processes are governed by inflammatory mediators including cytokines, chemokines, and immune cells. Though the effects of cachexia can be partially explained by direct effects of disease processes on wasting tissues, a growing body of evidence shows the central nervous system (CNS) also plays an essential mechanistic role in cachexia. In the context of inflammatory stress, the hypothalamus integrates signals from peripheral systems, which it translates into neuroendocrine perturbations, altered neuronal signaling, and global metabolic derangements. Therefore, we will discuss how hypothalamic inflammation is an essential driver of both the acute illness response and cachexia, and why this organ is uniquely equipped to generate and maintain chronic inflammation. First, we will focus on the role of the hypothalamus in acute responses to dietary and infectious stimuli. Next, we will discuss the role of cytokines in driving homeostatic disequilibrium, resulting in muscle wasting, anorexia, and weight loss. Finally, we will address mechanisms and mediators of chronic hypothalamic inflammation, including endothelial cells, chemokines, and peripheral leukocytes. PMID:26541482

  7. Inappropriate prescribing in an acutely ill population of elderly patients as determined by Beers' Criteria.

    Gallagher, Paul F

    2012-02-03

    INTRODUCTION: Adverse drug events (ADEs) are associated with inappropriate prescribing (IP) and result in increased morbidity, mortality and resource utilisation. We used Beers\\' Criteria to determine the three-month prevalence of IP in a non-selected community-dwelling population of acutely ill older people requiring hospitalisation. METHODS: A prospective, observational study of 597 consecutive acute admissions was performed. Diagnoses and concurrent medications were recorded before hospital physician intervention, and Beers\\' Criteria applied. RESULTS: Mean patient age (SD) was 77 (7) years. Median number of medications was 5, range 0-13. IP occurred in 32% of patients (n = 191), with 24%, 6% and 2% taking 1, 2 and 3 inappropriate medications respectively. Patients taking >5 medications were 3.3 times more likely to receive an inappropriate medication than those taking < or =5 medications (OR 3.34: 95%, CI 2.37-4.79; P<0.001). Forty-nine per cent of patients with inappropriate prescriptions were admitted with adverse effects of the inappropriate medications. Sixteen per cent of all admissions were associated with such adverse effects. CONCLUSION: IP is highly prevalent in acutely ill older patients and is associated with polypharmacy and hospitalisation. However, Beers\\' Criteria cannot be used as a gold standard as they do not comprehensively address all aspects of IP in older people.

  8. Management of Critically Ill Patients with Severe Acute Respiratory Syndrome (SARS

    2004-03-01

    Full Text Available Severe acute respiratory syndrome (SARS is frequently complicated with acute respiratory failure. In this article, we aim to focus on the management of the subgroup of SARS patients who are critically ill. Most SARS patients would require high flow oxygen supplementation, 20–30% required intensive care unit (ICU or high dependency care, and 13–26% developed acute respiratory distress syndrome (ARDS. In some of these patients, the clinical course can progress relentlessly to septic shock and/or multiple organ dysfunction syndrome (MODS. The management of critically ill SARS patients requires timely institution of pharmacotherapy where applicable and supportive treatment (oxygen therapy, noninvasive and invasive ventilation. Superimposed bacterial and other opportunistic infections are common, especially in those treated with mechanical ventilation. Subcutaneous emphysema, pneumothoraces and pneumomediastinum may arise spontaneously or as a result of positive ventilatory assistance. Older age is a consistently a poor prognostic factor. Appropriate use of personal protection equipment and adherence to infection control measures is mandatory for effective infection control. Much of the knowledge about the clinical aspects of SARS is based on retrospective observational data and randomized-controlled trials are required for confirmation. Physicians and scientists all over the world should collaborate to study this condition which may potentially threaten human existence.

  9. Intensity-Modulated Radiation Therapy Significantly Improves Acute Gastrointestinal Toxicity in Pancreatic and Ampullary Cancers

    Purpose: Among patients with upper abdominal malignancies, intensity-modulated radiation therapy (IMRT) can improve dose distributions to critical dose-limiting structures near the target. Whether these improved dose distributions are associated with decreased toxicity when compared with conventional three-dimensional treatment remains a subject of investigation. Methods and Materials: 46 patients with pancreatic/ampullary cancer were treated with concurrent chemoradiation (CRT) using inverse-planned IMRT. All patients received CRT based on 5-fluorouracil in a schema similar to Radiation Therapy Oncology Group (RTOG) 97-04. Rates of acute gastrointestinal (GI) toxicity for this series of IMRT-treated patients were compared with those from RTOG 97-04, where all patients were treated with three-dimensional conformal techniques. Chi-square analysis was used to determine if there was a statistically different incidence in acute GI toxicity between these two groups of patients. Results: The overall incidence of Grade 3-4 acute GI toxicity was low in patients receiving IMRT-based CRT. When compared with patients who had three-dimensional treatment planning (RTOG 97-04), IMRT significantly reduced the incidence of Grade 3-4 nausea and vomiting (0% vs. 11%, p = 0.024) and diarrhea (3% vs. 18%, p = 0.017). There was no significant difference in the incidence of Grade 3-4 weight loss between the two groups of patients. Conclusions: IMRT is associated with a statistically significant decrease in acute upper and lower GI toxicity among patients treated with CRT for pancreatic/ampullary cancers. Future clinical trials plan to incorporate the use of IMRT, given that it remains a subject of active investigation.

  10. Nutritional support and gastrointestinal disease.

    Hennessy, K

    1989-06-01

    The use of nutritional support in patients with acute gastrointestinal disease requires a thorough knowledge of the pathophysiology and nutritional alterations that are caused by the disease process. Although nutritional therapy of a patient with gastrointestinal disease is not curative of the underlying disease, it does provide essential support to the patient, which improves response to, and eventual recovery from, illness. Special considerations need to be made to avoid complicating the patient's condition by inappropriate use of nutritional support solutions, which can lead to abnormal liver function. PMID:2498848

  11. INTRA-ABDOMINAL HYPERTENSION AS A RISK FACTOR FOR ACUTE KIDNEY INJURY IN CRITICALLY ILL PATIENTS

    2016-05-01

    Full Text Available BACKGROUND AND AIMS Increased intra-abdominal pressure (IAP, also referred to as intra-abdominal hypertension (IAH, affects organ function in critically ill patients. The prevalence of IAH is between 32% - 65% in intensive care units. Normal IAP is ≈ 5–7 mmHg. According to WSACS definition, IAH = IAP ≥12 mmHg and is divided into 4 grades. They are Grade I (12-15 mmHg, Grade II (16-20 mmHg, Grade III (21-25 mmHg, Grade IV (>25 mmHg. Transvesical measurement of IAP currently is the most popular technique. Several systems with or without the need for electronic equipment are available that allow IAP measurement. The aim is to study the incidence of IAH in critically ill patients, to assess the risk factors for development of IAH, to study the role of IAH as a risk factor for Acute Kidney Injury (AKI, to assess the role of IAH as a risk factor for increased (Intensive Care Unit ICU mortality. SUBJECTS AND METHODS This is a prospective observational study. Study period was six months. The study included 52 patients admitted to Medical ICU in Government Medical College, Kozhikode, Kerala. RESULTS AND CONCLUSION There was a very high incidence of intra-abdominal hypertension in critically ill patients. IAH was significantly associated with risk factors like sepsis, mechanical ventilation, pancreatitis, capillary leak, ascites, cumulative fluid balance and cirrhosis. IAH is an independent risk factor for development of acute kidney injury. IAH is an independent predictor of mortality in critically ill patients.

  12. Plasticity of the systemic inflammatory response to acute infection during critical illness: development of the riboleukogram.

    Jonathan E McDunn

    Full Text Available BACKGROUND: Diagnosis of acute infection in the critically ill remains a challenge. We hypothesized that circulating leukocyte transcriptional profiles can be used to monitor the host response to and recovery from infection complicating critical illness. METHODOLOGY/PRINCIPAL FINDINGS: A translational research approach was employed. Fifteen mice underwent intratracheal injections of live P. aeruginosa, P. aeruginosa endotoxin, live S. pneumoniae, or normal saline. At 24 hours after injury, GeneChip microarray analysis of circulating buffy coat RNA identified 219 genes that distinguished between the pulmonary insults and differences in 7-day mortality. Similarly, buffy coat microarray expression profiles were generated from 27 mechanically ventilated patients every two days for up to three weeks. Significant heterogeneity of VAP microarray profiles was observed secondary to patient ethnicity, age, and gender, yet 85 genes were identified with consistent changes in abundance during the seven days bracketing the diagnosis of VAP. Principal components analysis of these 85 genes appeared to differentiate between the responses of subjects who did versus those who did not develop VAP, as defined by a general trajectory (riboleukogram for the onset and resolution of VAP. As patients recovered from critical illness complicated by acute infection, the riboleukograms converged, consistent with an immune attractor. CONCLUSIONS/SIGNIFICANCE: Here we present the culmination of a mouse pneumonia study, demonstrating for the first time that disease trajectories derived from microarray expression profiles can be used to quantitatively track the clinical course of acute disease and identify a state of immune recovery. These data suggest that the onset of an infection-specific transcriptional program may precede the clinical diagnosis of pneumonia in patients. Moreover, riboleukograms may help explain variance in the host response due to differences in ethnic

    2013-01-01

    Acute kidney injury (AKI) frequently occurs in the setting of critical illness and its management poses a challenge for the intensivist. Optimal management of volume status is critical in the setting of AKI in the ICU patient. The use of urine sodium, the fractional excretion of sodium (FeNa), and the fractional excretion of urea (FeUrea) are common clinical tools used to help guide fluid management especially further volume expansion but should be used in the context of the patient’s overall...

  14. MR findings of acute graft-versus-host disease involving gastrointestinal tracts

    To evaluate the MR findings of gastrointestinal graft-versus-host disease (GVHD) after allogenic bone marrow transplantation. Five patients (M:F=3:2, age range: 9-58 years) with suspected gastrointestinal GVHD underwent abdominal MRI, and the findings were evaluated. Because of acute myelocytic leukemia (n=4) or non-Hodgkin's lymphoma (n=1), all had undergone allogenic bone marrow transplantation 2-6 (mean, 3.5) weeks earlier. T2-weighted half-fourier acquisition snapshot turbo spin-echo, T1-weighted spoiled gradient-echo (SGE), and postcontrast T1-weighted SGE MR imaging, with and without fat-suppression, was performed. All five patients showed bowel wall thickening and marked contrast enhancement in the jejunum (n=5), ileum (n=4), duodenum (n=3), sigmoid colon (n=3), gastric antrum (n=2), and rectum (n=2). Bowel wall thickening showed a target appearance in the jejunum (n=2, 40.4%), lieum (n=1, 25.0%), sigmoid colon (n=1, 33.3%), and rectum (n=1, 50.0%), while the remaining cases showed diffuse wall thickening without layering. Small amount of ascites was noted in four patients (80%), and multiple small conglomerated retroperitoneal lymph nodes in three (60%). In all patients, a signal intensity of slightly enlarged liver due to iron overload secondary to multiple blood transfusions, gave rise to decreased signal intensity at both T1- and T2-weighted MR imaging. In patients with GVHD, the commonly noted MR findings were bowel was thickening with contrast enhancement, ascites and retroperitoneal lymphadenopathy

  15. Protective effect of adeturone on protein assimilation in the gastro-intestinal tract following acute X-irradiation

    The effect of adeturone and AET on the process of assimilation of food stuffs in the gastro-intestinal tract and possibilities for its protection from radiation injury were studied. Comparative assessment of the protective capabilities of adeturone and AET on the process of protein hydrolysis and absorption in the gastro-intestinal tract and the loss of serum proteins in the small intestines in acute X-irradiation revealed that the two radioprotectors adeturone and AET, being chemical agents, induce almost identical and transient changes in the absorption of protein hydrolysis products in the gastro-intestinal tract. These changes seem to have no aggravating effect on the course of radiation injury. In comparison with AET, adeturone exerts superior radioprotective effect on the processes studied, following exposure to a lethal X-ray dose of 800 r. (author)

    2013-01-01

    During the Yushu Earthquake on April 14,2010,a large number of rescuers from sea level or lowlands ascended to the quake areas very rapidly or rapidly less than 24 h.However,Yushu Earthquake is the highest quake in the world at altitudes between 3750 m and 4878 m where is a serious hypoxic environment.A high incidence of acute altitude illness was found in the unacclimatized rescuers; the mountain rescue operation changed as "rescue the rescuers".Lesson from the Yushu Earthquake is that the occurrence of acute altitude illness may be closely related to the ascent schedules.This prompted us to study the relationship between ascent rate and the incidence and severity of acute altitude illness; five different groups were compared.The first group was 42 sea level male young soldiers who ascended to quake area very rapidly within 8 h at 4000 m; the second group was 48 sea level male young soldiers who ascended to 4000 m rapidly less than 18 h; the third group was 66 acclimatized medical workers from 2261 m who ascended to 4000 m rapidly within 12 h; the fourth group was 56 Tibetan medical workers from 2800 m who ascended to 4000 m rapidly within 8 h; the fifth group was 50 male sea level workers who ascended to 4000 m gradually over a period of 4 d.The results showed that the sea level rescuers ascended to 4000 m very rapidly or rapidly had the highest incidence of acute mountain sickness (AMS) with the greatest AMS scores and the lowest arterial oxygen saturation (SaO2) ; the sea level workers ascended to 4000 m gradually had moderate incidence of AMS with moderate AMS scores and SaO2 values; whereas the acclimatized and adapted rescuers had the lowest incidence of AMS,lowest AMS scores and higher SaO2; especially none AMS occurred in Tibetan rescuers.AMS score is inversely related to the ascent rate (r=-0.24,p<0.001).Additionally,acute altitude illness is significantly influenced by altitude acclimatization.The ascent rate is inversely related to

    2005-05-01

    Full Text Available Abstract Background Some individuals with functional gastrointestinal disorders (FGID suffer long-lasting symptoms without ever consulting their doctors. Our aim was to study co-morbidity and lifestyle differences among consulters and non-consulters with persistent FGID and controls in a defined adult population. Methods A random sample of the general adult Swedish population was obtained by a postal questionnaire. The Abdominal Symptom Questionnaire (ASQ was used to measure GI symptomatology and grade of GI symptom severity and the Complaint Score Questionnaire (CSQ was used to measure general symptoms. Subjects were then grouped for study by their symptomatic profiles. Subjects with long-standing FGID (n = 141 and subjects strictly free from gastrointestinal (GI symptoms (n = 97 were invited to attend their local health centers for further assessment. Results Subjects with FGID have a higher risk of psychological illness [OR 8.4, CI95(4.0–17.5] than somatic illness [OR 2.8, CI95(1.3–5.7] or ache and fatigue symptoms [OR 4.3, CI95(2.1–8.7]. Subjects with psychological illness have a higher risk of severe GI symptoms than controls; moreover they have a greater chance of being consulters. Patients with FGID have more severe GI symptoms than non-patients. Conclusion There is a strong relation between extra-intestinal, mental and somatic complaints and FGID in both patients and non-patients. Psychological illness increases the chance of concomitantly having more severe GI symptoms, which also enhance consultation behaviour.

  2. Endoscopic management of acute gastrointestinal bleeding in children: Time for a radical rethink.

    Thomson, Mike; Belsha, Dalia

    2016-02-01

    Currently we are no nearer than 10 or 20years ago providing a safe, adequate, and effective round-the-clock endoscopic services for acute life-threatening gastrointestinal bleeding in children. Preventable deaths are occurring still, and it is a tragedy. This is owing to a number of factors which require urgent attention. Skill-mix and the ability of available endoscopists in the UK are woeful. Manpower is spread too thinly and not concentrated in centers of excellence, which is necessary given the relative rarity of the presentation. Adult gastroenterologists are increasingly reticent regarding their help in increasingly litigious times. Recent work on identification of those children likely to require urgent endoscopic intervention has mirrored scoring systems that have been present in adult circles for many years and may allow appropriate and timely intervention. Recent technical developments such as that of Hemospray® may lower the threshold of competency in dealing with this problem endoscopically, thus allowing lives to be saved. Educational courses, mannequin and animal model training are important but so will be appropriate credentialing of individuals for this skill-set. Assessment of competency will become the norm and guidelines on a national level in each country mandatory if we are to move this problem from the "too difficult" to the "achieved". It is an urgent problem and is one of the last emergencies in pediatrics that is conducted poorly. This cannot and should not be allowed to continue unchallenged. PMID:26703435

    Objectives Plasma tryptophan levels are associated with delirium in critically ill patients. Although tryptophan has been linked to the pathogenesis of other neurocognitive diseases through metabolism to neurotoxins via the kynurenine pathway, a role for kynurenine pathway activity in intensive care unit brain dysfunction (delirium and coma) remains unknown. This study examined the association between kynurenine pathway activity as determined by plasma kynurenine concentrations and kynurenine/tryptophan ratios and presence or absence of acute brain dysfunction (defined as delirium/coma-free days) in intensive care unit patients. Design, Setting, and Patients This was a prospective cohort study that utilized patient data and blood samples from the Maximizing Efficacy of Targeted Sedation and Reducing Neurologic Dysfunction trial, which compared sedation with dexmedetomidine vs. lorazepam in mechanically ventilated patients. Measurements and Main Results Baseline plasma kynurenine and tryptophan concentrations were measured using high-performance liquid chromatography with or without tandem mass spectrometry. Delirium was assessed daily using the Confusion Assessment Method for the Intensive Care Unit. Linear regression examined associations between kynurenine pathway activity and delirium/coma-free days after adjusting for sedative exposure, age, and severity of illness. Among 84 patients studied, median age was 60 yrs and Acute Physiology and Chronic Health Evaluation II score was 28.5. Elevated plasma kynurenine and kynurenine/tryptophan ratio were both independently associated with significantly fewer delirium/coma-free days (i.e., fewer days without acute brain dysfunction). Specifically, patients with plasma kynurenine or kynurenine/tryptophan ratios at the 75th percentile of our population had an average of 1.8 (95% confidence interval 0.6–3.1) and 2.1 (95% confidence interval 1.0–3.2) fewer delirium/coma-free days than those patients with values at the 25

  8. There is need for antigen-based rapid diagnostic tests to identify common acute tropical illnesses.

    Wilde, Henry; Suankratay, Chusana

    2007-01-01

    Enteric fever, typhus, leptospirosis, dengue, melioidosis, and tuberculous meningitis present urgent diagnostic problems that require experience and clinical judgment to make early evidence-based management decisions. Basic and applied research dealing with reliable antigen-based diagnostics has been published and confirmed for several of these infections. This should have initiated commercial production but has not. Established international firms see little profit in such diagnostic kits since they would be used in poor countries with little prospects for return of investment capital. We attempt to illustrate this issue, using common causes of acute febrile illnesses in the Southeast Asian region. We believe that rapid diagnostic technology could prevent significant delay in starting appropriate therapy, reduce hospital expenses, and even save lives. PMID:17617848

  9. Frequency of co-existence of dengue and malaria in patients presenting with acute febrile illness

    To find out the frequency of co-existence of malaria and dengue fever in patients presenting with acute febrile illness. Methods: The descriptive cross-sectional study was conducted at the Military Hospital Rawalpindi from June to November 2012. A total of 500 patients with complaint of acute febrile illness were selected after applying the inclusion and exclusion criteria. Preliminary data was collected on a pretested proforma. Blood samples of patients were tested for dengue serology and malaria parasite. Results were entered in respective proforma. Co-existence was considered present when a patient had both dengue serology and malaria parasite slide positive. SPSS 20 was used for data analysis. Result: Of the total, 349 (69.8%) were males and 151 (30.2%) females. Dengue serology was positive in 16 (3.2%); 81(16.2%) had malaria parasite slide positive; 403 (80.4%) had none of the two findings. Co-existence of both dengue and malaria was nil among the whole sample. In males, 67 (13.4%) had malaria, while 11 (2.2%) had dengue. In females, 14 (2.8%) had malaria, while 5 (1%) suffered from dengue fever. Conclusion: Co-existence of dengue and malaria was zero per cent in 500 patients visiting Military Hospital Rawalpindi. More studies shall be conducted to find out whether the reason of having zero per cent co-existence is that dengue or/and malaria epidemic did not occur in 2012 or whether there are some other factors involved.

  10. Severe Acute Respiratory Illness (SARI) Surveillance in Louisiana, 2013-2014.

    Hand, Julie P; Serrano, Jose; Johnson, Jenna I; Jespersen, Megan; Ratard, Raoult C

    2015-01-01

    The objectives of this article are to describe the severe acute respiratory illness (SARI) surveillance implemented in Louisiana during the 2013-2014 influenza season, present the epidemiology of reported SARI cases, and identify ways to improve this system by incorporating formal SARI surveillance into the influenza surveillance program. Of the 212 SARI cases, 181 (85%) had at least one underlying medical condition, 54 (25.7%) had two conditions, 43 (20.3%) had three conditions, and 25 (11.8%) reported four or more. The most common four underlying conditions were: obesity (43.4%), chronic cardiac conditions (39.6%), diabetes (29.7%), and chronic pulmonary conditions (26.9%). While obesity was the most reported underlying condition, it was three times more likely to be reported in less than 65 years old rather than those >65. Continuation of SARI data collection in future seasons will allow comparisons regarding severity, populations affected, and identify risk factors most commonly associated with severe illness. Reporting of SARI cases also increased influenza-associated adult mortality reporting to the Office of Public Health's Office of Infectious Diseases Epidemiology (ID Epi). Though all influenza-associated mortality is reportable in Louisiana, adult mortality was reported rarely prior to the 2013-2014 season. PMID:27159455

  14. Design of Fuzzy Controller for Supplying Oxygen in Sub-acute Respiratory Illnesses

    Mohamed Ibrahim El Adawy

    2012-05-01

    Full Text Available The knowledge in this paper describe methods and systems for supplying supplemental oxygen to patients for use in sub-acute respiratory illnesses which maintains healthy blood oxygen content in the patients by controlled dosing of oxygen with a measured response to the patient's actual blood oxygen content are disclosed. The dosing can be provided by simple ON/OFF control over the delivery of oxygen or the amount of oxygen delivered to the patient with each inhalation can be varied in response to the patient's need as determined by a more sophisticated control scheme, such as PID (proportional-integral-derivative controller and Fuzzy logic control (FLC that utilizes the difference between the patient's actual blood oxygen content and a target blood oxygen content and/or trends in the blood oxygen content. The systems and methods are particularly directed at patients receiving supplemental oxygen therapy in a sub-acute care environment. The result of the two controllers is good and best one is the fuzzy logic algorithm.

  15. The value of multidetector-row computed tomography for localization of obscure acute gastrointestinal bleeding

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

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

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

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

    2014-12-01

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

  19. PROPOSAL OF A CLINICAL CARE PATHWAY FOR THE MANAGEMENT OF ACUTE UPPER GASTROINTESTINAL BLEEDING

    2015-12-01

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

    Background Safety of fibreoptic bronchoscopy (FOB) in nonintubated critically ill patients with acute respiratory failure have not been extensively evaluated. We aimed to measure the incidence of intubation and need to increase ventilatory support following FOB and to identify predictive factors of this event. Methods A prospective multicenter observational study was carried out in 8 French adult intensive care units. 169 FOB performed in patients with a PaO2/FiO2 ratio equal or less than 300 were analyzed. Our main end point was intubation rate. The secondary end point was rate of increased ventilatory support defined as greater than a 50% increase in oxygen requirement, the need to start non invasive-positive pressure ventilation (NI-PPV) or increase NI-PPV support. Results Within 24 hours, an increase in ventilatory support was required following 59 (35%) bronchoscopies, of which 25 (15%) led to endotracheal intubation. The existence of chronic obstructive pulmonary disease (COPD) (OR:5.2 [1.6–17.8], p=0.007) or immunosuppression (OR : 5.4 [1.7–17.2], p=0.004) were significantly associated with the need for intubation in multivariable analysis. None of the baseline physiological parameters including the PaO2/FiO2 ratio was associated with intubation. Conclusion Bronchoscopy is often followed by an increase in ventilatory support in hypoxemic critically ill patients, but less frequently by the need for intubation. COPD, immunosuppression are associated with a need for invasive ventilation in the following 24 hours. PMID:23070123

    Full Text Available Acute kidney injury (AKI is common in critically ill patients. Diuretics are used without any evidence demonstrating a beneficial effect on renal function. The objective of the present study is to determine the incidence of AKI in an intensive care unit (ICU and if there is an association between the use of furosemide and the development of AKI. The study involved a hospital cohort in which 344 patients were consecutively enrolled from January 2010 to January 2011. A total of 132 patients (75 females and 57 males, average age 64 years remained for analysis. Most exclusions were related to ICU discharge in the first 24 h. Laboratory, sociodemographic and clinical data were collected until the development of AKI, medical discharge or patient death. The incidence of AKI was 55% (95%CI = 46-64. The predictors of AKI found by univariate analysis were septic shock: OR = 3.12, 95%CI = 1.36-7.14; use of furosemide: OR = 3.27, 95%CI = 1.57-6.80, and age: OR = 1.02 (95%CI = 1.00-1.04. Analysis of the subgroup of patients with septic shock showed that the odds ratio of furosemide was 5.5 (95%CI = 1.16-26.02 for development of AKI. Age, use of furosemide, and septic shock were predictors of AKI in critically ill patients. Use of furosemide in the subgroup of patients with sepsis/septic shock increased (68.4% the chance of development of AKI when compared to the sample as a whole (43.9%.

    2016-01-01

    Background Most acute febrile illnesses (AFI) are usually not associated with a specific diagnosis because of limitations of available diagnostics. This study reports on the frequency of EBV viremia and viral load in children and adults presenting with febrile illness in hospitals in Kenya. Methodology/Principal Findings A pathogen surveillance study was conducted on patients presenting with AFI (N = 796) at outpatient departments in 8 hospitals located in diverse regions of Kenya. Enrollment criterion to the study was fever without a readily diagnosable infection. All the patients had AFI not attributable to the common causes of fever in Kenyan hospitals, such as malaria or rickettsiae, leptospira, brucella and salmonella and they were hence categorized as having AFI of unknown etiology. EBV was detected in blood using quantitative TaqMan-based qPCR targeting a highly conserved BALF5 gene. The overall frequency of EBV viremia in this population was 29.2%, with significantly higher proportion in younger children of 15 years). With respect to geographical localities, the frequency of EBV viremia was higher in the Lake Victoria region (36.4%), compared to Kisii highland (24.6%), Coastal region (22.2%) and Semi-Arid region (25%). Furthermore, patients from the malaria endemic coastal region and the Lake Victoria region presented with significantly higher viremia than individuals from other regions of Kenya. Conclusions/Significance This study provides profiles of EBV in patients with AFI from diverse eco-regions of Kenya. Of significant interest is the high frequency of EBV viremia in younger children. The observed high frequencies of EBV viremia and elevated viral loads in residents of high malaria transmission areas are probably related to malaria induced immune activation and resultant expansion of EBV infected B-cells.

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

    Full Text Available Acute kidney injury (AKI often associated with a high hospital morbi-mortality rate in the intensive care unit patients. Kidney injury molecule-1 (KIM-1, has many characteristics of ideal biomarker for kidney injury. The aim of this study was to compared the temporal pattern of elevation urinary KIM-1 level following critically ill children with SCr as standart biomarker of AKI. Prospective analytic observational study was conducted during October to March 2014 in the Saiful Anwar General Hospital and Physiology Laboratory Brawijaya University. There were 13 critically ill as subjects. SCr and KIM-1 levels from all subjects were measured three times ( at admission, after 1st and 6th hour. Subjects were devided into AKI - non-AKI groups by SCr level and survivor - non survivor group at the and of the observations. Results showed that there were significantly increased levels of KIM-1 in the AKI and non-AKI and survivor-non survivor group at time point. However, we found that delta KIM-1 at time point increased significant in non AKI group and survivor group. KIM-1 at admission can diagnosed AKI in critically ill children. We conclude that urinary KIM-1 is a sensitive non-invasive biomarker to diagnosed acute kidney injury in critically ill children. Increase level of KIM-1 by time shows protective and good outcome in critically ill children.

  6. A Therapeutic Dose of Ketoprofen Causes Acute Gastrointestinal Bleeding, Erosions, and Ulcers in Rats

    Shientag, Lisa J; Wheeler, Suzanne M; Garlick, David S.; Maranda, Louise S

    2012-01-01

    Perioperative treatment of several rats in our facility with ketoprofen (5 mg/kg SC) resulted in blood loss, peritonitis, and death within a day to a little more than a week after surgery that was not related to the gastrointestinal tract. Published reports have established the 5-mg/kg dose as safe and effective for rats. Because ketoprofen is a nonselective nonsteroidal antiinflammatory drug that can damage the gastrointestinal tract, the putative diagnosis for these morbidities and mortalit...

  7. Acute blood volume expansion delays the gastrointestinal transit of a charcoal meal in awake rats

    de-Oliveira G.R.

    1998-01-01

    Full Text Available The present study evaluates the effect of blood volume expansion on the gastrointestinal transit of a charchoal meal (2.5 ml of an aqueous suspension consisting of 5% charcoal and 5% gum arabic in awake male Wistar rats (200-270 g. On the day before the experiments, the rats were anesthetized with ether, submitted to left jugular vein cannulation and fasted with water ad libitum until 2 h before the gastrointestinal transit measurement. Blood volume expansion by iv infusion of 1 ml/min Ringer bicarbonate in volumes of 3, 4 or 5% body weight delayed gastrointestinal transit at 10 min after test meal administration by 21.3-26.7% (P<0.05, but no effect was observed after 1 or 2% body weight expansion. The effect of blood volume expansion (up to 5% body weight on gastrointestinal transit lasted for at least 60 min (P<0.05. Mean arterial pressure increased transiently and central venous pressure increased and hematocrit decreased (P<0.05. Subdiaphragmatic vagotomy and yohimbine (3 mg/kg prevented the delay caused by expansion on gastrointestinal transit, while atropine (0.5 mg/kg, L-NAME (2 mg/kg, hexamethonium (10 mg/kg, prazosin (1 mg/kg or propranolol (2 mg/kg were ineffective. These data show that blood volume expansion delays the gastrointestinal transit of a charcoal meal and that vagal and yohimbine-sensitive pathways appear to be involved in this phenomenon. The delay in gastrointestinal transit observed here, taken together with the modifications of gastrointestinal permeability to salt and water reported by others, may be part of the mechanisms involved in liquid excess management.

  8. Analysis of Dosimetric Parameters Associated With Acute Gastrointestinal Toxicity and Upper Gastrointestinal Bleeding in Locally Advanced Pancreatic Cancer Patients Treated With Gemcitabine-Based Concurrent Chemoradiotherapy

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

  11. Update: outbreak of acute febrile illness among athletes participating in Eco-Challenge-Sabah 2000--Borneo, Malaysia, 2000.

    2001-01-19

    During September 7-11, 2000, CDC was notified by the Idaho Department of Health, the Los Angeles County Department of Health Services, and the GeoSentinel Global Surveillance Network of at least 20 cases of acute febrile illness in three countries; all ill patients had participated in the Eco-Challenge-Sabah 2000 multisport expedition race in Borneo, Malaysia, during August 21-September 3, 2000. Participants included athletes from 29 U.S. states and 26 countries. This report updates the ongoing investigation of this outbreak through December 2, which suggests that Leptospira were the cause of illness and that water from the Segama River was the primary source of infection. Participants in adventure sports and exotic tourism should be aware of potential exposure to unusual and emerging infectious agents. PMID:11215718

    Classical dengue fever is characterized by the clinical features of fever, headache, severe myalgia and occasionally rash, which can also be caused by a number of other viral and bacterial infections. Five hundred and fifty eight patients who fulfilled the criteria of clinical diagnosis of acute dengue from 4 government outpatient polyclinics were recruited in this prospective field study. Of the 558 patients, 190 patients were categorized as acute dengue fever, 86 as recent dengue and 282 as non-dengue febrile illnesses based on the results of a number of laboratory tests. Epidemiological features of febrile patients showed that the mean age of patients in the dengue fever group was significantly younger in comparison with patients in the non-dengue group. There was no significant difference between the two groups with respect to gender but there was significant ethnic difference with foreign workers representing a higher proportion in the dengue fever group. Patients with acute dengue fever were more likely to have patient-reported rash and a history of dengue in family or neighbourhood but less likely to have respiratory symptoms, sore-throat and jaundice in comparison to patients with non-dengue febrile illnesses. As with patients with dengue fever, patients in the recent dengue group were more likely to have history of patient-reported rash and a history of dengue contact and less likely to have respiratory symptoms in comparison to patients with non-dengue febrile illnesses. In contrast to patients with dengue fever, patients in the recent dengue group were more likely to have abdominal pain and jaundice in comparison to non-dengue febrile patients. The finding strongly suggests that a proportion of patients in the recent dengue group may actually represent a subset of patients with acute dengue fever at the late stage of illness. PMID:21901948

    Short-term exposure to air pollution may be linked to negative health outcomes that require an emergency medical response. However, few studies have been undertaken on this phenomenon to date. The aim of this study therefore was to examine the association between short-term exposure to ambient suspended particulate matter (SPM) and emergency ambulance dispatches (EADs) for acute illness in Japan. Daily EAD data, daily mean SPM and meteorological data were obtained for four prefectures in the Kanto region of Japan for the period from 2007 to 2011. The area-specific association between daily EAD for acute illness and SPM was explored using generalized linear models while controlling for ambient temperature, relative humidity, seasonality, long-term trends, day of the week and public holidays. Stratified analyses were conducted to evaluate the modifying effects of age, sex and medical conditions. Area-specific estimates were combined using meta-analyses. For the total study period the mean level of SPM was 23.7μg/m(3). In general, higher SPM was associated with a significant increase in EAD for acute illness [estimated pooled relative risk (RR): 1.008, 95% CI: 1.007 to 1.010 per 10μg/m(3) increase in SPM at lag 0-1]. The effects of SPM on EAD for acute illness were significantly greater for moderate/mild medical conditions (e.g. cases that resulted in 3weeks hospitalization or which resulted in death). Using EAD data, this study has shown the adverse health effects of ambient air pollution. This highlights the importance of reducing the level of air pollution in order to maintain population health and well-being. PMID:27235903

Based on robust data from randomized controlled studies and meta-analyses showing a reduced incidence of VTE by 40% to about 60% with pharmacologic thromboprophylaxis, prevention of VTE with low molecular weight heparin (LMWH, unfractionated heparin (UFH, or fondaparinux is currently recommended in all at-risk hospitalized acutely ill medical patients. In patients who are bleeding or are at high risk for major bleeding, mechanical prophylaxis with graduated compression stockings or intermittent pneumatic compression may be suggested. Thromboprophylaxis is generally continued for 6 to 14 days or for the duration of hospitalization. Selected cases could benefit from extended thromboprophylaxis beyond this period, although the risk of major bleeding remains a concern, and additional studies are needed to identify patients who may benefit from prolonged prophylaxis. For hospitalized acutely ill medical patients with renal insufficiency, a low dose (1.5 mg once daily of fondaparinux or prophylactic LMWH subcutaneously appears to have a safe profile, although proper evaluation in randomized studies is lacking. The evidence on the use of prophylaxis for VTE in this latter group of patients, as well as in those at higher risk of bleeding complications, such as patients with thrombocytopenia, remains scarce. For critically ill patients

    Understanding healthcare-seeking patterns for respiratory illness can help improve estimations of disease burden and inform public health interventions to control acute respiratory disease in Indonesia. The objectives of this study were to describe healthcare-seeking behaviors for respiratory illnesses in one rural and one urban community in Western Java, and to explore the factors that affect care seeking. From February 8, 2012 to March 1, 2012, a survey was conducted in 2520 households in the East Jakarta and Bogor districts to identify reported recent respiratory illnesses, as well as all hospitalizations from the previous 12-month period. We found that 4% (10% of those less than 5years) of people had respiratory disease resulting in a visit to a healthcare provider in the past 2weeks; these episodes were most commonly treated at government (33%) or private (44%) clinics. Forty-five people (0.4% of those surveyed) had respiratory hospitalizations in the past year, and just over half of these (24/45, 53%) occurred at a public hospital. Public health programs targeting respiratory disease in this region should account for care at private hospitals and clinics, as well as illnesses that are treated at home, in order to capture the true burden of illness in these communities.

  19. Acute undifferentiated febrile illness in rural Cambodia: a 3-year prospective observational study.

    Tara C Mueller

    Full Text Available In the past decade, malaria control has been successfully implemented in Cambodia, leading to a substantial decrease in reported cases. Wide-spread use of malaria rapid diagnostic tests (RDTs has revealed a large burden of malaria-negative fever cases, for which no clinical management guidelines exist at peripheral level health facilities. As a first step towards developing such guidelines, a 3-year cross-sectional prospective observational study was designed to investigate the causes of acute malaria-negative febrile illness in Cambodia. From January 2008 to December 2010, 1193 febrile patients and 282 non-febrile individuals were recruited from three health centers in eastern and western Cambodia. Malaria RDTs and routine clinical examination were performed on site by health center staff. Venous samples and nasopharyngeal throat swabs were collected and analysed by molecular diagnostic tests. Blood cultures and blood smears were also taken from all febrile individuals. Molecular testing was applied for malaria parasites, Leptospira, Rickettsia, O. tsutsugamushi, Dengue- and Influenza virus. At least one pathogen was identified in 73.3% (874/1193 of febrile patient samples. Most frequent pathogens detected were P. vivax (33.4%, P. falciparum (26.5%, pathogenic Leptospira (9.4%, Influenza viruses (8.9%, Dengue viruses (6.3%, O. tsutsugamushi (3.9%, Rickettsia (0.2%, and P. knowlesi (0.1%. In the control group, a potential pathogen was identified in 40.4%, most commonly malaria parasites and Leptospira. Clinic-based diagnosis of malaria RDT-negative cases was poorly predictive for pathogen and appropriate treatment. Additional investigations are needed to understand their impact on clinical disease and epidemiology, and the possible role of therapies such as doxycycline, since many of these pathogens were seen in non-febrile subjects.

    2016-01-01

    Full Text Available Background: Chikungunya fever (CHIK is an arboviral disease. Dengue fever (DENG and CHIK are indistinguishable clinically and need to be differentiated by laboratory investigations. Purpose: This study aimed at estimating the seroprevalence of CHIK mono-infection and CHIK and DENG dual infection in suspected patients. We also analyzed the age, sex distribution, joint involvement, and relation of joint movement restriction with visual analog scale (VAS. Materials and Methods: Two hundred patients clinically suspected with DENG and CHIK were enrolled from a Tertiary Care Hospital in Mumbai from April 2012 to October 2013. The detailed history and examination findings were recorded. Serum samples were subjected to DENG and CHIK immunoglobulin G (IgM enzyme-linked immunosorbent assay (ELISA. Results: The seroprevalence of CHIK was 12.5%. Mono-infection of CHIK was 3%, and CHIK and DENG dual infection was 9.5%. Most affected age group in CHIK cases was 46-60 years wherein female preponderance was seen. All 6 patients with CHIK mono-infection had fever and joint involvement; knee and elbow were the most commonly affected joints. All CHIK patients had VAS score of 6-10 with restricted joint movement. Of the patients with dual infection, the majorities were from 31 to 45 years with male preponderance; all had fever and joint pain mainly affecting knee and elbow. Of patients who had VAS score 6-10 in patients with dual infection, only 5.26% had restricted joint movement. Conclusion: IgM ELISA for Chikungunya infection should be included in the routine laboratory tests for acute febrile illness.

  1. The predictive value of the NICE "red traffic lights" in acutely ill children.

    Evelien Kerkhof

    Full Text Available OBJECTIVE: Early recognition and treatment of febrile children with serious infections (SI improves prognosis, however, early detection can be difficult. We aimed to validate the predictive rule-in value of the National Institute for Health and Clinical Excellence (NICE most severe alarming signs or symptoms to identify SI in children. DESIGN, SETTING AND PARTICIPANTS: The 16 most severe ("red" features of the NICE traffic light system were validated in seven different primary care and emergency department settings, including 6,260 children presenting with acute illness. MAIN OUTCOME MEASURES: We focussed on the individual predictive value of single red features for SI and their combinations. Results were presented as positive likelihood ratios, sensitivities and specificities. We categorised "general" and "disease-specific" red features. Changes in pre-test probability versus post-test probability for SI were visualised in Fagan nomograms. RESULTS: Almost all red features had rule-in value for SI, but only four individual red features substantially raised the probability of SI in more than one dataset: "does not wake/stay awake", "reduced skin turgor", "non-blanching rash", and "focal neurological signs". The presence of ≥ 3 red features improved prediction of SI but still lacked strong rule-in value as likelihood ratios were below 5. CONCLUSIONS: The rule-in value of the most severe alarming signs or symptoms of the NICE traffic light system for identifying children with SI was limited, even when multiple red features were present. Our study highlights the importance of assessing the predictive value of alarming signs in clinical guidelines prior to widespread implementation in routine practice.

  2. Disparities in smoking and acute respiratory illnesses among sexual minority young adults.

    Blosnich, John; Jarrett, Traci; Horn, Kimberly

    2010-10-01

    Morbidity and mortality from cigarette smoking remain major public health issues. Particularly, smoking has been associated with increased risk of acute respiratory illnesses (ARIs). Literature indicates that lesbian, gay, and bisexual (i.e., sexual minority) persons smoke more than the general population. Additionally, young adulthood is the second-most prevalent period of smoking uptake. Given this constellation of risk correlates, the authors examined whether sexual minority young adults experience increased odds of ARIs (i.e., strep throat, bronchitis, sinus infection, and asthma). Using cross-sectional data from the Spring 2006 National College Health Assessment, prevalence estimates of smoking were generated among young adult (age range, 18-24 years) lesbian/gay, bisexual, unsure, and heterosexual college students (n = 75,164). Nested logistic regression analyses were used to examine whether smoking status mediated the risk of ARIs among sexual orientation groups. Compared with heterosexual smokers, gay/lesbian smokers were more likely to have had strep throat, and bisexual smokers were more likely to have had sinus infection, asthma, and bronchitis. Whereas smoking mediated the risk of ARI, sexual minorities still showed higher odds of ARIs after adjustment for smoking. Sexual minority young adults may experience respiratory health disparities that may be linked to their higher smoking rates, and their higher rates of smoking lend urgency to the need for cessation interventions. Future studies are needed to explore whether chronic respiratory disease caused by smoking (i.e., lung cancer, COPD, emphysema) disproportionately affect sexual minority populations. PMID:20496074

    Biomarker studies for early detection of acute kidney injury (AKI) have been limited by nonselective testing and uncertainties in using small changes in serum creatinine as a reference standard. Here we examine the ability of urine L-type fatty acid-binding protein (L-FABP), neutrophil gelatinase-associated lipocalin (NGAL), interleukin-18 (IL-18), and kidney injury molecule-1 (KIM-1) to predict injury progression, dialysis, or death within 7 days in critically ill adults with early AKI. Of 152 patients with known baseline creatinine examined, 36 experienced the composite outcome. Urine L-FABP demonstrated an area under the receiver-operating characteristic curve (AUC-ROC) of 0.79 (95% confidence interval 0.70-0.86), which improved to 0.82 (95% confidence interval 0.75-0.90) when added to the clinical model (AUC-ROC of 0.74). Urine NGAL, IL-18, and KIM-1 had AUC-ROCs of 0.65, 0.64, and 0.62, respectively, but did not significantly improve discrimination of the clinical model. The category-free net reclassification index improved with urine L-FABP (total net reclassification index for nonevents 31.0%) and urine NGAL (total net reclassification index for events 33.3%). However, only urine L-FABP significantly improved the integrated discrimination index. Thus, modest early changes in serum creatinine can help target biomarker measurement for determining prognosis with urine L-FABP, providing independent and additive prognostic information when combined with clinical predictors.

  4. Gastrointestinal illness among triathletes swimming in non-polluted versus polluted seawater affected by heavy rainfall, Denmark, 2010-2011.

    Nina Majlund Harder-Lauridsen

    Full Text Available Recent years have seen an increase in the frequency of extreme rainfall and subsequent flooding across the world. Climate change models predict that such flooding will become more common, triggering sewer overflows, potentially with increased risks to human health. In August 2010, a triathlon sports competition was held in Copenhagen, Denmark, shortly after an extreme rainfall. The authors took advantage of this event to investigate disease risks in two comparable cohorts of physically fit, long distance swimmers competing in the sea next to a large urban area. An established model of bacterial concentration in the water was used to examine the level of pollution in a spatio-temporal manner. Symptoms and exposures among athletes were examined with a questionnaire using a retrospective cohort design and the questionnaire investigation was repeated after a triathlon competition held in non-polluted seawater in 2011. Diagnostic information was collected from microbiological laboratories. The results showed that the 3.8 kilometer open water swimming competition coincided with the peak of post-flooding bacterial contamination in 2010, with average concentrations of 1.5x10(4 E. coli per 100 ml water. The attack rate of disease among 838 swimmers in 2010 was 42% compared to 8% among 931 swimmers in the 2011 competition (relative risk (RR 5.0; 95% CI: 4.0-6.39. In 2010, illness was associated with having unintentionally swallowed contaminated water (RR 2.5; 95% CI: 1.8-3.4; and the risk increased with the number of mouthfuls of water swallowed. Confirmed aetiologies of infection included Campylobacter, Giardia lamblia and diarrhoeagenic E. coli. The study demonstrated a considerable risk of illness from water intake when swimming in contaminated seawater in 2010, and a small but measureable risk from non-polluted water in 2011. This suggests a significant risk of disease in people ingesting small amounts of flood water following extreme rainfall in

  6. Neurochemical mechanism of the gastrointestinal interdigestive migrating motor complex in rats with acute inflammatory stomach ache

    Xiaoli Xu; Qin Li; Lv Zhou; Liqiang Ru

    2012-01-01

    The normal gastrointestinal interdigestive migrating motor complex cycle was interrupted, and paroxysmal contraction appeared after formaldehyde-induced stomach ache. Activities of nitric oxide synthase, acetylcholinesterase and vasoactive intestinal peptide neurons were significantly reduced, whereas activities of calcitonin gene-related peptide neurons were significantly increased in the pyloric sphincter muscular layer, myenteric nerve plexus and submucous nerve plexus. Electroacupuncture at Zusanli (ST36) suppressed paroxysmal contraction in rats with formaldehyde-induced stomach ache, and neurons in the enteric nervous system were normal. These results indicated that nitrergic neurons, cholinergic neurons, vasoactive intestinal peptide neurons and calcitonin gene-related peptide neurons in the enteric nervous system may be involved in changes to the gastrointestinal interdigestive migrating motor complex following stomach ache, and that electroacupuncture can regulate this process.

  7. Prospects for management of gastrointestinal injury associated with the acute radiation syndrome

    The effect of total-body ionizing radiation on the digestive tract is dose-dependent and time-dependent. At low doses (1.5 Gy), one observes only a short prodromal syndrome consisting of nausea, vomiting, and gastric suppression. At doses greater than 6 Gy, the prodromal syndrome is more marked, and it is followed after a 2-5-day remission period by a subacute syndrome, characterized by diarrhea and hematochezia. This gastrointestinal syndrome is superimposed onto a radiation-induced bone marrow suppression. The combination of intestinal and hemopoietic syndromes results in dehydration, anemia, and infection, leading eventually to irreversible shock and death. The treatment of prodromal symptoms is based on the administration of antiemetics and gastrokinetics, although an effective treatment devoid of side effects is not yet available for human therapy. The treatment of the gastrointestinal subacute syndrome remains difficult and unsuccessful after exposure to total body doses greater than 8-10 Gy. Supportive therapy to prevent infection and dehydration may be effective if restoration or repopulation of the intestinal and bone marrow stem cells does occur. In addition, bone marrow transplantation may improve the prospect of treating the hemopoietic syndrome, although the experience gained in Chernobyl suggests that this treatment is difficult to apply in the case of nuclear accidents. Administration of radioprotectants before irradiation decreases damage to healthy cells, while not protecting cancerous tissues. In the future, stimulation of gastrointestinal and hemopoietic progenitor cells may be possible using cell growth regulators, but much remains to be done to improve the treatment of radiation damage to the gastrointestinal tract. 77 references

    2006-02-01

    Full Text Available Abstract Background Infectious gastrointestinal illness (IGI outbreaks have been reported in U.S. Navy ships and could potentially have an adverse mission impact. Studies to date have been anecdotal. Methods We conducted a retrospective analysis of weekly reported disease and non-battle injury health data collected in 2000 – 2001 from 44 U.S. Navy ships while sailing in the 5th Fleet (Persian Gulf and nearby seas. Results During this period, 11 possible IGI outbreaks were identified. Overall, we found 3.3 outbreaks per 100 ship-weeks, a mean outbreak duration of 4.4 weeks, and a mean cumulative ship population attack rate of 3.6%. Morbidity, represented by days lost due to personnel being placed on sick-in-quarters status, was higher during outbreak weeks compared to non-outbreak weeks (p = 0.002. No clear seasonal distribution was identified. Conclusion Explosive outbreaks due to viruses and bacteria with the potential of incapacitating large proportions of the crew raise serious concerns of mission impact and military readiness.

    2014-01-01

    Background Risk for acute kidney injury (AKI) in older adults has not been systematically evaluated. We sought to delineate the determinants of risk for AKI in older compared to younger adults. Study Design Retrospective analysis of patients hospitalized in July 2000–September 2008. Setting & Participants We identified all adult patients admitted to an intensive care unit (ICU) (n=45,655) in a large tertiary care university hospital system. We excluded patients receiving dialysis or kidney transplant prior to hospital admission, and patients with baseline creatinine ≥ 4 mg/dl, liver transplantation, indeterminate AKI status, or unknown age, leaving 39,938 patients. Predictor We collected data on multiple susceptibilities and exposures including age, sex, race, body mass, comorbid conditions, severity of illness, baseline kidney function, sepsis, and shock. Outcomes We defined AKI according to KDIGO (Kidney Disease: Improving Global Outcomes) criteria. We examined susceptibilities and exposures across age strata for impact on development of AKI. Measurements We calculated area under the receiver operating characteristic curve (AUC) for prediction of AKI across age groups. Results 25,230 patients (63.2%) were aged 55 years or older. Overall 25,120 patients (62.9%) developed AKI (69.2% aged 55 years or older). Examples of risk factors for AKI in the oldest age category (75 years or older) were drugs (vancomycin, aminoglycosides, nonsteroidal anti-inflammatories), history of hypertension (OR, 1.13; 95% CI, 1.02–1.25) and sepsis (OR, 2.12; 95% CI, 1.68–2.67). Fewer variables remained predictive of AKI as age increased and the model for older patients was less predictive (p<0.001). For the age categories 18–54, 55–64, 65–74, and 75 years or older, the AUCs were 0.744 (95% CI, 0.735–0.752), 0.714 (95% CI, 0.702–0.726), 0.706 (95% CI, 0.693–0.718), and 0.673 (95% CI, 0.661–0.685), respectively. Limitations Analysis may not apply to non-ICU patients

    2013-04-01

    Full Text Available ABSTRACT. BACKGROUND: Fever is a burning issue in the tropics and the mos t common cause of morbidity. Quite frequently this fever goes undi agnosed because of many reasons like the lack of diagnostic facilities, insufficient epidemi ological data available on causes of fever, and so on. This research study was aimed to find out the e tiology and clinical markers of Acute Undifferentiated Febrile Illness [AUFI] among the r ural population of Southern India. METHODOLOGY: This prospective, observational study was conducted at Government Villupuram Medical College and Hospital, a rural ter tiary care centre in Tamil Nadu, India. Consecutive hospitalised adult patients [>16 years] with AUFI[5-14 days fever] were enrolled into the study from August 2010 to February 2012 [1 8 months].Upon enrollment, detailed history was recorded, physical examination done and basic blood tests including biochemical examination, smear study for malaria, blood culture s and serology for the commonly encountered infections were done according to study protocol. The patients were followed up until clinical recovery and convalescence. The data were entered in MS excel and analyzed using Epi-info software 2008 version. RESULTS: A total of 403 patients were included in the study . The distribution of AUFI included Malaria 133[33%], Typhoid 83[20.59%], Dengue 42[10.4%], Leptospirosis 25[6.2%], and other causes 36[8.9%] and unknown cause 84[20.84%]. Malaria patients were significantly associated with jaundice , altered mentation, travel outside the district, elevated AST/ALT levels, thrombocytopenia and splenomegaly. Typhoid fever was associated with longer fever duration, abdominal pai n, coated tongue, relative bradycardia, normal platelet counts and low leucocyte count. Deng ue fever could be predicted by rash, pruritis, petechiae ,retro-orbital pain and low platele t counts. Leptospirosis patients showed significant association with conjunctival suffusion , muscle

  11. A prospective study of symptoms, function, and medication use during acute illness in nursing home residents: design, rationale and cohort description

    Liu Sophia

    2010-07-01

    Full Text Available Abstract Background Nursing home residents are at high risk for developing acute illnesses. Compared with community dwelling adults, nursing home residents are often more frail, prone to multiple medical problems and symptoms, and are at higher risk for adverse outcomes from acute illnesses. In addition, because of polypharmacy and the high burden of chronic disease, nursing home residents are particularly vulnerable to disruptions in transitions of care such as medication interruptions in the setting of acute illness. In order to better estimate the effect of acute illness on nursing home residents, we have initiated a prospective cohort which will allow us to observe patterns of acute illnesses and the consequence of acute illnesses, including symptoms and function, among nursing home residents. We also aim to examine the patterns of medication interruption, and identify patient, provider and environmental factors that influence continuity of medication prescribing at different points of care transition. Methods This is a prospective cohort of nursing home residents residing in two nursing homes in a metropolitan area. Baseline characteristics including age, gender, race, and comorbid conditions are recorded. Participants are followed longitudinally for a planned period of 3 years. We record acute illness incidence and characteristics, and measure symptoms including depression, pain, withdrawal symptoms, and function using standardized scales. Results 76 nursing home residents have been followed for a median of 666 days to date. At baseline, mean age of residents was 74.4 (± 11.9; 32% were female; 59% were white. The most common chronic conditions were dementia (41%, depression (38%, congestive heart failure (25% and chronic obstructive lung disease (27%. Mean pain score was 4.7 (± 3.6 on a scale of 0 to 10; Geriatric Depression Scale (GDS-15 score was 5.2 (± 4.4. During follow up, 138 acute illness episodes were identified, for an

    Full Text Available Abstract Background Enteric pathogens are an important cause of illness, however, little is known about their community-level risk factors (e.g., socioeconomic, cultural and physical environmental conditions in the Northwest Territories (NWT of Canada. The objective of this study was to undertake ecological (group-level analyses by combining two existing data sources to examine potential community-level risk factors for campylobacteriosis, giardiasis and salmonellosis, which are three notifiable (mandatory reporting to public health authorities at the time of diagnosis enteric infections. Methods The rate of campylobacteriosis was modeled using a Poisson distribution while rates of giardiasis and salmonellosis were modeled using a Negative Binomial distribution. Rate ratios (the ratio of the incidence of disease in the exposed group to the incidence of disease in the non-exposed group were estimated for infections by the three major pathogens with potential community-level risk factors. Results Significant (p≤0.05 associations varied by etiology. There was increased risk of infection with Salmonella for communities with higher proportions of ‘households in core need’ (unsuitable, inadequate, and/or unaffordable housing up to 42% after which the rate started to decrease with increasing core need. The risk of giardiasis was significantly higher both with increased ‘internal mobility’ (population moving between communities, and also where the community’s primary health facility was a health center rather than a full-service hospital. Communities with higher health expenditures had a significantly decreased risk of giardiasis. Results of modeling that focused on each of Giardia and Salmonella infections separately supported and expanded upon previous research outcomes that suggested health disparities are often associated with socioeconomic status, geographical and social mobility, as well as access to health care (e.g. facilities

    1982-01-01

    The low thyroxine (T4) state of acute critical nonthyroidal illnesses is characterized by marked decreases in serum total T4 and triiodothyronine (T3) with elevated reverse T3 (rT3) values. To better define the mechanisms responsible for these alterations, serum kinetic disappearance studies of labeled T4, T3, or rT3 were determined in 16 patients with the low T4 state and compared with 27 euthyroid controls and a single subject with near absence of thyroxine-binding globulin. Marked increase...

  18. Influenza Sentinel Surveillance among Patients with Influenza-Like-Illness and Severe Acute Respiratory Illness within the Framework of the National Reference Laboratory, Niger, 2009-2013.

    Halima Boubacar Maïnassara

    Full Text Available Little is known about the epidemiology of influenza in Africa, including Niger. We documented the epidemiology of seasonal and pandemic influenza among outpatients with influenza-like-illness (ILI and inpatients with severe acute respiratory illness (SARI presenting at selected sentinel sites in Niger from April 2009 through April 2013.Patients meeting the ILI or the SARI case definitions and presenting at the outpatient or inpatient departments of selected sentinel sites were enrolled. Epidemiological data and nasopharyngeal swabs were collected. The respiratory samples were tested by real-time reverse transcription polymerase chain reaction.From April 2009 to April 2013, laboratory results were obtained from 1176 ILI and 952 SARI cases, of which 146 (12% and 54 (6% tested positive for influenza virus, respectively. The influenza positivity rate was highest in the 5-14 year age-group (32/130; 24% among ILI patients and 6/61; 10% among SARI patients followed by the 1-4 year age-group (69/438; 16% among ILI patients and 32/333; 9% among SARI patients. Of the 200 influenza positive cases 104 (52% were A(H1N1pdm09, 62 (31% were A(H3N2 and 34 (17% were B. Influenza viruses were detected predominantly from November to April with peak viral activity observed in February.The Niger sentinel surveillance system allowed to monitor the circulation of seasonal influenza as well as the introduction and spread of influenza A(H1N1pdm09 in the country. Continuous influenza surveillance is needed to better understand the epidemiology of seasonal influenza and monitor the emergence of influenza strains with pandemic potential.

  19. Likely health outcomes for untreated acute febrile illness in the tropics in decision and economic models; a Delphi survey.

    Yoel Lubell

    Full Text Available BACKGROUND: Modelling is widely used to inform decisions about management of malaria and acute febrile illnesses. Most models depend on estimates of the probability that untreated patients with malaria or bacterial illnesses will progress to severe disease or death. However, data on these key parameters are lacking and assumptions are frequently made based on expert opinion. Widely diverse opinions can lead to conflicting outcomes in models they inform. METHODS AND FINDINGS: A Delphi survey was conducted with malaria experts aiming to reach consensus on key parameters for public health and economic models, relating to the outcome of untreated febrile illnesses. Survey questions were stratified by malaria transmission intensity, patient age, and HIV prevalence. The impact of the variability in opinion on decision models is illustrated with a model previously used to assess the cost-effectiveness of malaria rapid diagnostic tests. Some consensus was reached around the probability that patients from higher transmission settings with untreated malaria would progress to severe disease (median 3%, inter-quartile range (IQR 1-5%, and the probability that a non-malaria illness required antibiotics in areas of low HIV prevalence (median 20%. Children living in low transmission areas were considered to be at higher risk of progressing to severe malaria (median 30%, IQR 10-58% than those from higher transmission areas (median 13%, IQR 7-30%. Estimates of the probability of dying from severe malaria were high in all settings (medians 60-73%. However, opinions varied widely for most parameters, and did not converge on resurveying. CONCLUSIONS: This study highlights the uncertainty around potential consequences of untreated malaria and bacterial illnesses. The lack of consensus on most parameters, the wide range of estimates, and the impact of variability in estimates on model outputs, demonstrate the importance of sensitivity analysis for decision models

    The intestinal inflammation caused by intestinal ischemia reperfusion during acute pancreatitis (AP) often leads to multiple organ dysfunction and aggravation of acute pancreatitis. This review concerns up-date progress of the pathophysiology and molecular mechanism of the excessive production of gut-derived cytokines. The regulation effects of immuno-neuro-endocrine network for pancreatic necrosis are the basis for pharmacological therapeutic in AP. The translation from basic research to clinical trials for the prevention or treatment of severe acute pancreatitis (SAP) is of great value. Early enteral nutrition is necessary for the restitution, proliferation, and differentiation of the intestinal epithelial cells adjacent to the wounded area. Clearance of the excess intestinal bacteria and supplement of probiotics may be helpful to prevent bacterial translocation and infection of pancreas. PMID:23782148

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

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

    After allogeneic stem cell transplant, severe grade III-IV gastrointestinal (GI) acute GvHD is associated with significant morbidity and mortality, and generally results in poor outcomes. Salvage therapy for patients who fail steroid therapy is not well defined in the literature. In the current retrospective study, we reviewed our experience with the combination of basiliximab and infliximab in 21 patients with severe, grade III-IV GI acute GvHD of whom 16 met the definition for steroid-refractory disease. The overall response rate was 76%, with 43% CR at a median time of 21 days after beginning treatment. The survival at 1 year was 24%, with most deaths due to complications from GvHD and recurrence of primary disease. All five of the long-term survivors have chronic GvHD. On the basis of a review of the literature, this regimen does not seem to be significantly more effective than other strategies for severe GI GvHD and seems to be worse than the results reported for basiliximab alone. Future studies of single-agent basiliximab and newer agents are required. PMID:26479982

  3. Dose–Volume Effects on Patient-Reported Acute Gastrointestinal Symptoms During Chemoradiation Therapy for Rectal Cancer

    Purpose: Research on patient-reported outcomes (PROs) in rectal cancer is limited. We examined whether dose–volume parameters of the small bowel and large bowel were associated with patient-reported gastrointestinal (GI) symptoms during 5-fluorouracil (5-FU)–based chemoradiation treatment for rectal cancer. Methods and Materials: 66 patients treated at the Brigham and Women’s Hospital or Massachusetts General Hospital between 2006 and 2008 were included. Weekly during treatment, patients completed a questionnaire assessing severity of diarrhea, urgency, pain, cramping, mucus, and tenesmus. The association between dosimetric parameters and changes in overall GI symptoms from baseline through treatment was examined by using Spearman’s correlation. Potential associations between these parameters and individual GI symptoms were also explored. Results: The amount of small bowel receiving at least 15 Gy (V15) was significantly associated with acute symptoms (p = 0.01), and other dosimetric parameters ranging from V5 to V45 also trended toward association. For the large bowel, correlations between dosimetric parameters and overall GI symptoms at the higher dose levels from V25 to V45 did not reach statistical significance (p = 0.1), and a significant association was seen with rectal pain from V15 to V45 (p < 0.01). Other individual symptoms did not correlate with small bowel or large bowel dosimetric parameters. Conclusions: The results of this study using PROs are consistent with prior studies with physician-assessed acute toxicity, and they identify small bowel V15 as an important predictor of acute GI symptoms during 5-FU–based chemoradiation treatment. A better understanding of the relationship between radiation dosimetric parameters and PROs may allow physicians to improve radiation planning to optimize patient outcomes.

    Patients with severe hypernatremia who receive conventional treatment are often undertreated. Data on the management of acute hypernatremia using continuous venovenous hemofiltration (CVVH) are limited to anecdotes. This study aimed to evaluate the efficacy and safety of CVVH treatment for acute severe hypernatremia in critically ill patients in a retrospective cohort. A total of 95 patients who were admitted to our ICU between January 2009 and January 2014 were analyzed as the original cohort. These patients were divided into CVVH and conventional treatment groups. The patients in the conventional and CVVH groups were then matched by age, reason for ICU admission, vasopressor dependency, basic serum sodium concentration, and Glasgow scores. A Cox regression model was used to adjust the confounding variables. In the original cohort, the 28-day survival rates were 41.9% and 25.0% for the CVVH and conventional treatment groups, respectively. Conventional treatment (HR = 2.1, 95% CI 1.1-3.8, P = 0.019) was an independent predictor of patient mortality in the multivariate Cox regression model. In the matched cohort, the two groups were not significantly different in baseline characteristics. The CVVH group had a significantly greater reduction in the serum sodium concentration (0.78 [0.63-1.0] mmol/L/h versus 0.13 [0.009-0.33] mmol/L/h), P hypernatremia in critically ill patients.

  6. Dengue and other common causes of acute febrile illness in Asia: an active surveillance study in children.

    Maria Rosario Capeding

    Full Text Available BACKGROUND: Common causes of acute febrile illness in tropical countries have similar symptoms, which often mimic those of dengue. Accurate clinical diagnosis can be difficult without laboratory confirmation and disease burden is generally under-reported. Accurate, population-based, laboratory-confirmed incidence data on dengue and other causes of acute fever in dengue-endemic Asian countries are needed. METHODS AND PRINCIPAL FINDINGS: This prospective, multicenter, active fever surveillance, cohort study was conducted in selected centers in Indonesia, Malaysia, Philippines, Thailand and Vietnam to determine the incidence density of acute febrile episodes (≥ 38 °C for ≥ 2 days in 1,500 healthy children aged 2-14 years, followed for a mean 237 days. Causes of fever were assessed by testing acute and convalescent sera from febrile participants for dengue, chikungunya, hepatitis A, influenza A, leptospirosis, rickettsia, and Salmonella Typhi. Overall, 289 participants had acute fever, an incidence density of 33.6 per 100 person-years (95% CI: 30.0; 37.8; 57% were IgM-positive for at least one of these diseases. The most common causes of fever by IgM ELISA were chikungunya (in 35.0% of in febrile participants and S. Typhi (in 29.4%. The overall incidence density of dengue per 100 person-years was 3.4 by nonstructural protein 1 (NS1 antigen positivity (95% CI: 2.4; 4.8 and 7.3 (95% CI: 5.7; 9.2 by serology. Dengue was diagnosed in 11.4% (95% CI: 8.0; 15.7 and 23.9% (95% CI: 19.1; 29.2 of febrile participants by NS1 positivity and serology, respectively. Of the febrile episodes not clinically diagnosed as dengue, 5.3% were dengue-positive by NS1 antigen testing and 16.0% were dengue-positive by serology. CONCLUSIONS: During the study period, the most common identified causes of pediatric acute febrile illness among the seven tested for were chikungunya, S. Typhi and dengue. Not all dengue cases were clinically diagnosed; laboratory confirmation

    Full Text Available Concurrent infections with more than one etiological agent can result in an illness with overlapping symptoms, resulting in a situation where the diagnosis and management of such a patient could be challenging. We report a case of vivax malaria in a patient who was also serologically positive for leptospirosis and dengue.

  8. Estimated Glomerular Filtration Rate Correlates Poorly with Four-Hour Creatinine Clearance in Critically Ill Patients with Acute Kidney Injury

    Christopher J. Kirwan

    2013-01-01

    Full Text Available Introduction. RIFLE and AKIN provide a standardised classification of acute kidney injury (AKI, but their categorical rather than continuous nature restricts their use to a research tool. A more accurate real-time description of renal function in AKI is needed, and some published data suggest that equations based on serum creatinine that estimate glomerular filtration rate (eGFR can provide this. In addition, incorporating serum cystatin C concentration into estimates of GFR may improve their accuracy, but no eGFR equations are validated in critically ill patients with AKI. Aim. This study tests whether creatinine or cystatin-C-based eGFR equations, used in patients with CKD, offer an accurate representation of 4-hour creatinine clearance (4CrCl in critically ill patients with AKI. Methods. Fifty-one critically ill patients with AKI were recruited. Thirty-seven met inclusion criteria, and the performance of eGFR equations was compared to 4CrCl. Results. eGFR equations were better than creatinine alone at predicting 4CrCl. Adding cystatin C to estimates did not improve the bias or add accuracy. The MDRD 7 eGFR had the best combination of correlation, bias, percentage error and accuracy. None were near acceptable standards quoted in patients with chronic kidney disease (CKD. Conclusions. eGFR equations are not sufficiently accurate for use in critically ill patients with AKI. Incorporating serum cystatin C does not improve estimates. eGFR should not be used to describe renal function in patients with AKI. Standards of accuracy for validating eGFR need to be set.

    Although the severe acute respiratory illness (SARI) case definition is increasingly used for inpatient influenza surveillance, pneumonia is a more familiar term to clinicians and policymakers. We evaluated WHO case definitions for severe acute respiratory illness (SARI) and pneumonia (Integrated Management of Childhood Illnesses (IMCI) for children aged <5 years and Integrated Management of Adolescent and Adult Illnesses (IMAI) for patients aged ≥13 years) for detecting laboratory-confirmed influenza among hospitalized ARI patients. Sensitivities were 84% for SARI and 69% for IMCI pneumonia in children aged <5 years and 60% for SARI and 57% for IMAI pneumonia in patients aged ≥13 years. Clinical pneumonia case definitions may be a useful complement to SARI for inpatient influenza surveillance. PMID:27219455

  10. Acute respiratory infection as a cause of non-malarial febrile illness in African children.

    Florida Muro

    2015-01-01

    Full Text Available The replacement of “presumptive treatment for malaria” by “test before treat” strategies for the management of febrile illness is raising awareness of the importance of knowing more about the causes of illness in children who are suspected to have malaria but return a negative parasitological test. The most common cause of non-malarial febrile illness (NMFI in African children is respiratory tract infection. Whilst the bacterial causes of NMFI are well known, the increasing use of sensitive techniques such as polymerase chain reaction (PCR tests is revealing large numbers of viruses that are potential respiratory pathogens. However, many of these organisms are commonly present in the respiratory tract of healthy children so causality and risk factors for pneumonia remain poorly understood. Infection with a combination of viral and bacterial pathogens is increasingly recognised as important in the pathogenesis of pneumonia. Similarly, blood stream infections with organisms typically grown by aerobic culture are well known but a growing number of organisms that can be identified only by PCR, viral culture, or serology are now recognised to be common pathogens in African children. The high mortality of hospitalised children on the first or second day of admission suggests that, unless results are rapidly available, diagnostic tests to identify specific causes of illness will still be of limited use in guiding the potentially life‑saving decisions relating to initial treatment of children admitted to district hospitals in Africa with severe febrile illness and a negative test for malaria. Malaria control and the introduction of vaccines against Haemophilus influenzae type b and pneumococcal disease are contributing to improved child survival in Africa. However, increased parasitological testing for malaria is associated with increased use of antibiotics to which resistance is already high.

    Rationale: Acute lung injury (ALI) that develops 6 hours after transfusion (TRALI) is the leading cause of transfusion-related mortality. Several transfusion characteristics have been postulated as risk factors for TRALI, but the evidence is limited to retrospective studies.

  12. Concurrent acute illness and comorbid conditions poorly predict antibiotic use in upper respiratory tract infections: a cross-sectional analysis

    Perencevich Eli N

    2007-05-01

    Full Text Available Abstract Background Inappropriate antibiotic use promotes resistance. Antibiotics are generally not indicated for upper respiratory infections (URIs. Our objectives were to describe patterns of URI treatment and to identify patient and provider factors associated with antibiotic use for URIs. Methods This study was a cross-sectional analysis of medical and pharmacy claims data from the Pennsylvania Medicaid fee-for-service program database. We identified Pennsylvania Medicaid recipients with a URI office visit over a one-year period. Our outcome variable was antibiotic use within seven days after the URI visit. Study variables included URI type and presence of concurrent acute illnesses and chronic conditions. We considered the associations of each study variable with antibiotic use in a logistic regression model, stratifying by age group and adjusting for confounders. Results Among 69,936 recipients with URI, 35,786 (51.2% received an antibiotic. In all age groups, acute sinusitis, chronic sinusitis, otitis, URI type and season were associated with antibiotic use. Except for the oldest group, physician specialty and streptococcal pharyngitis were associated with antibiotic use. History of chronic conditions was not associated with antibiotic use in any age group. In all age groups, concurrent acute illnesses and history of chronic conditions had only had fair to poor ability to distinguish patients who received an antibiotic from patients who did not. Conclusion Antibiotic prevalence for URIs was high, indicating that potentially inappropriate antibiotic utilization is occurring. Our data suggest that demographic and clinical factors are associated with antibiotic use, but additional reasons remain unexplained. Insight regarding reasons for antibiotic prescribing is needed to develop interventions to address the growing problem of antibiotic resistance.

  16. Development of a Set of Nomograms to Predict Acute Lower Gastrointestinal Toxicity for Prostate Cancer 3D-CRT

    Purpose: To predict acute Radiation Therapy Oncology Group (RTOG)/European Organization for Research and Treatment of Cancer (EORTC) and Subjective Objective Signs Management and Analysis/Late Effect of Normal Tissue (SOMA/LENT) toxicities of the lower gastrointestinal (LGI) syndrome in patients with prostate cancer undergoing three-dimensional conformal radiotherapy using a tool (nomogram) that takes into account clinical and dosimetric variables that proved to be significant in the Italian Association for Radiation Oncology (AIRO) Group on Prostate Cancer (AIROPROS) 0102 trial. Methods and Materials: Acute rectal toxicity was scored in 1,132 patients by using both the RTOG/EORTC scoring system and a 10-item self-assessed questionnaire. Correlation between clinical variables/dose-volume histogram constraints and rectal toxicity was investigated by means of multivariate logistic analyses. Multivariate logistic analyses results were used to create nomograms predicting the symptoms of acute LGI syndrome. Results: Mean rectal dose was a strong predictor of Grade 2-3 RTOG/EORTC acute LGI toxicity (p 0.0004; odds ratio (OR) = 1.035), together with hemorrhoids (p = 0.02; OR 1.51), use of anticoagulants/antiaggregants (p = 0.02; OR = 0.63), and androgen deprivation (AD) (p = 0.04; OR = 0.65). Diabetes (p = 0.34; OR 1.28) and pelvic node irradiation (p = 0.11; OR = 1.56) were significant variables to adjust toxicity prediction. Bleeding was related to hemorrhoids (p = 0.02; OR = 173), AD (p = 0.17; OR = 0.67), and mean rectal dose (p 0.009; OR = 1.024). Stool frequency was related to seminal vesicle irradiation (p = 0.07; OR = 6.46), AD administered for more than 3 months (p = 0.002; OR = 0.32), and the percent volume of rectum receiving more than 60 Gy (V60Gy) V60 (p = 0.02; OR = 1.02). Severe fecal incontinence depended on seminal vesicle irradiation (p = 0.14; OR = 4.5) and V70 (p = 0.033; OR 1.029). Conclusions: To the best of our knowledge, this work presents the

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

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

  19. Síndrome do ceco móvel e as doenças gastrintestinais funcionais Mobile cecum sindrome and the functional gastrointestinal illnesses

    Júlio César Monteiro dos Santos Jr.

    2006-12-01

    Full Text Available O ceco móvel é uma variação anatômica embriológica do ceco e cólon ascendente resultante da descida incompleta desses segmentos do intestino grosso e da não fixação no peritônio da goteira parieto-cólica direita. A falta dessa fusão permite movimentação do ceco e/ou do cólon ascendente, facilitando a torção sobre seu eixo longitudinal ou a dobra medial do ceco sobre si, ficando encostado com sua borda medial à borda medial do cólon ascendente. Esse fato causa sintomas intermitentes de obstrução parcial do intestino ou, no caso de torção completa (volvo, de obstrução aguda com possível necrose do segmento envolvido. A anormalidade embriológica tem alta incidência (10 a 30% na população, contudo só tem sido mencionada por ocasião da torção completa, inadequadamente denominada de volvo do ceco-ascendente, em geral com necrose cecal. Dessa forma, a ocorrência não é das mais comuns e está citada entre as causas de obstrução intestinal aguda, perfazendo, nos adultos e nas crianças, menos do que 2% de todos os casos de obstruções intestinais, mas com a importância de destaque por causa do alto índice de morbi-mortalidade entre os pacientes afetados. O objetivo foi apresentar o ceco móvel como causa de dor abdominal intermitente, distensão, empachamento e cólica de origens obscuras em pessoas de aparência saudável, mas com uma longa história de distúrbios gastrintestinais funcionais, associados à constipação e/ou diarréia, portanto, com um quadro sintomatológico sobreponível ao da síndrome do cólon irritável. Além disso, propomos um marcador anatômico para a síndrome do cólon irritável, seja o subtipo com constipação predominante, seja o da diarréia predominante ou a forma em que há alternância entre constipação e diarréia e a possibilidade de alívio daqueles sintomas com a cecopexia.Functional gastrointestinal (FGI disorders are chronic or periodic conditions characterized by

    2014-10-15

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

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

    Full Text Available David Basic,1 Tabitha J Hartwell2 1Department of Geriatric Medicine, Liverpool Hospital, Sydney, NSW, Australia; 2Department of Geriatric Medicine and Rehabilitation, Shoalhaven District Memorial Hospital, Nowra, NSW, Australia Purpose: To examine the association between falls in hospital and new placement in a nursing home among older people hospitalized with acute illness.Materials and methods: This prospective cohort study of 2,945 consecutive patients discharged alive from an acute geriatric medicine service used multivariate logistic regression to model the association between one or more falls and nursing home placement (primary analysis. Secondary analyses stratified falls by injury and occurrence of multiple falls. Demographic, medical, and frailty measures were considered in adjusted models.Results: The mean age of all patients was 82.8±7.6 years and 94% were admitted through the emergency department. During a median length of stay (LOS of 11 days, 257 (8.7% patients had a fall. Of these, 66 (25.7% sustained an injury and 53 (20.6% had two or more falls. Compared with nonfallers, fallers were more likely to be placed in a nursing home (odds ratio [OR]: 2.03, 95% confidence interval [CI]: 1.37–3.00, after adjustment for age, sex, frailty, and selected medical variables (including dementia and delirium. Patients without injury (OR: 1.83, 95% CI: 1.17–2.85 and those with injury (OR: 2.35, 95% CI: 1.15–4.77 were also more likely to be placed. Patients who fell had a longer LOS (median 19 days vs 10 days; P<0.001.Conclusion: This study of older people in acute care shows that falls in the hospital are significantly associated with new placement in a nursing home. Given the predominantly negative experiences and the financial costs associated with placement in a nursing home, fall prevention should be a high priority in older people hospitalized with acute illness.

    Visfatin is a recently described protein that is thought to regulate the process of adipocyte differentiation. Findings suggest that visfatin may be actively involved in the control of weight regulatory networks. However, to what extent and which role it plays in eating disorders is still poorly understood, as mixed results have been reported. The aim of the current study was to investigate serum visfatin concentrations on a cross sectional sample between acute anorexia nervosa patients (n=44), weight recovered patients (n=13) and healthy controls (n=46) and a longitudinal sample of acute patients (n=57) during weight recovery at three different time-points. Results did not show significant differences in visfatin between the three groups; however, acute patients showed a higher visfatin/BMI-SDS ratio than controls and recovered patients. Longitudinal results revealed an increase of visfatin levels during therapy. Our results suggest that high ratios of visfatin/BMI-SDS could be a state marker in acute anorexia nervosa, displaying a compensatory mechanism of the individual to maintain normal visfatin levels under malnourished conditions.

  9. Acute interventional diagnosis and treatment of upper gastrointestinal arterial hemorrhage: its clinical value and influence factors

    Objective: To evaluate emergent angiography and interventional management in treating massive upper gastrointestinal (GI) arterial hemorrhage, and to discuss the factors influencing the angiographic bleeding signs and the interventional therapeutic results. Methods: The clinical data of 56 patients with massive upper GI arterial hemorrhage, who underwent diagnostic arteriography and interventional management with trans-catheter vasopressin infusion and embolization, were retrospectively analyzed. Systolic blood pressure of both pre-and post-interventional therapy was recorded and statistically analyzed. The arteriographic positive rates were separately calculated according to the catheter tip's location, being placed at the 2nd grade branch or at the 3 rd -4 th grade branch of the artery, and the relation of the positive rate with the tip's location was analyzed. A comparison of the hemostatic effect between trans-catheter vasopressin infusion and trans-catheter embolization was made. Results: The average systolic blood pressure of pre-and post-procedure was (93.14 ± 18.63) mmHg and (11.64 ± 13.61) mmHg respectively, with a significant difference (P = 0.023). The angiographic bleeding signs were demonstrated in 12 cases (21.4%) with the catheter's tip at the 2nd grade branch and in 56 cases (100%) with the catheter's tip at the 3 rd -4 th grade branch,the difference between the two was of statistically significance (P < 0.05). The technical success rate and the clinical hemostasis rate of via catheter vasopressin infusion was 80% (16 / 20) and 55% (11/20) respectively. Of nine re-bleeding cases, seven were successfully controlled with embolization therapy by using microcatheter and two had to receive surgery because of arterial rupture which was proved by angiography. The technical and the clinical rates of success for transcatheter embolization therapy were 93% (42 / 45) and 89% (40 / 45) respectively. Recurrence of bleeding was seen in two patients who got

    In 2009, an increased proportion of suspected dengue cases reported to the surveillance system in Puerto Rico were laboratory negative. As a result, enhanced acute febrile illness (AFI) surveillance was initiated in a tertiary care hospital. Patients with fever of unknown origin for 2-7 days duration were tested for Leptospira, enteroviruses, influenza, and dengue virus. Among the 284 enrolled patients, 31 dengue, 136 influenza, and 3 enterovirus cases were confirmed. Nearly half (48%) of the confirmed dengue cases met clinical criteria for influenza. Dengue patients were more likely than influenza patients to have hemorrhage (81% versus 26%), rash (39% versus 9%), and a positive tourniquet test (52% versus 18%). Mean platelet and white blood cell count were lower among dengue patients. Clinical diagnosis can be particularly difficult when outbreaks of other AFI occur during dengue season. A complete blood count and tourniquet test may be useful to differentiate dengue from other AFIs. PMID:23382160

  11. Challenges in the Etiology and Diagnosis of Acute Febrile Illness in Children in Low- and Middle-Income Countries.

    Iroh Tam, Pui-Ying; Obaro, Stephen K; Storch, Gregory

    2016-06-01

    Acute febrile illness is a common cause of hospital admission, and its associated infectious causes contribute to substantial morbidity and death among children worldwide, especially in low- and middle-income countries. Declining transmission of malaria in many regions, combined with the increasing use of rapid diagnostic tests for malaria, has led to the increasing recognition of leptospirosis, rickettsioses, respiratory viruses, and arboviruses as etiologic agents of fevers. However, clinical discrimination between these etiologies can be difficult. Overtreatment with antimalarial drugs is common, even in the setting of a negative test result, as is overtreatment with empiric antibacterial drugs. Viral etiologies remain underrecognized and poorly investigated. More-sensitive diagnostics have led to additional dilemmas in discriminating whether a positive test result reflects a causative pathogen. Here, we review and summarize the current epidemiology and focus particularly on children and the challenges for future research. PMID:27059657

  12. Self reported incidence and morbidity of acute respiratory illness among deployed U.S. military in Iraq and Afghanistan.

    Bryony W Soltis

    Full Text Available BACKGROUND: Historically, respiratory infections have had a significant impact on U.S. military missions. Deployed troops are particularly at high risk due to close living conditions, stressful work environments and increased exposure to pathogens. To date, there are limited data available on acute respiratory illness (ARI among troops deployed in support of ongoing military operations, specifically Operation Enduring Freedom (OEF and Operation Iraqi Freedom (OIF. METHODS: Using self-report data from two sources collected from troops deployed to Iraq, Afghanistan and the surrounding region, we analyzed incidence and risk factors for ARI. Military personnel on mid-deployment Rest & Recuperation (R&R or during redeployment were eligible to participate in the voluntary self-report survey. RESULTS: Overall, 39.5% reported having at least one ARI. Of these, 18.5% sought medical care and 33.8% reported having decreased job performance. The rate of self-reported ARI was 15 episodes per 100 person-months among those taking the voluntary survey, and 24.7 episodes per 100 person-months among those taking the clinic health questionnaire. Negative binomial regression analysis found female sex, Navy branch of service and lack of flush toilets to be independently associated with increased rates of ARI. Deployment to OIF, increasing age and higher rank were also positively associated with ARI risk. CONCLUSIONS: The overall percentage of deployed military personnel reporting at least one acute respiratory illness decreased since earlier parts of OIF/OEF. However, the reported effect on job performance increased tremendously. The most important factors associated with increased respiratory infection are female sex, Navy branch of service, lack of improved latrine facilities, deployment to OIF, increasing age and higher rank.

  13. INTRA-ABDOMINAL HYPERTENSION AS A RISK FACTOR FOR ACUTE KIDNEY INJURY IN CRITICALLY ILL PATIENTS

    2016-01-01

    BACKGROUND AND AIMS Increased intra-abdominal pressure (IAP), also referred to as intra-abdominal hypertension (IAH), affects organ function in critically ill patients. The prevalence of IAH is between 32% - 65% in intensive care units. Normal IAP is ≈ 5–7 mmHg. According to WSACS definition, IAH = IAP ≥12 mmHg and is divided into 4 grades. They are Grade I (12-15 mmHg), Grade II (16-20 mmHg), Grade III (21-25 mmHg), Grade IV (>25 mmHg). Transvesical measurement of IAP curren...

  14. Detection of acute gastrointestinal bleeding by means of technetium-99m in vivo labelled red blood cells

    Prognosis of gastrointestinal (GI) bleeding depends on the timely and accurate detection of the source of bleeding and sequential surgical or endoscopy therapy. Scintigraphy with red blood cells (RBCs) in vivo labelled by means of technetium-99m hastened detection of source of GI bleeding and improved management of the particular disease. Gastrointestinal endoscopy is the method of choice for the diagnostics of bleeding from upper tract and large bowel. For diagnostics of bleeding from the small bowel we can use scintigraphy with in vivo labelled autological red blood cells if pushenteroscopy, intra-operative enteroscopy or angiography are not available. 31 patients (13 men, 18 women, aged 20-91, mean 56 years) underwent this investigation from 1998 till 2001 at the Department of Nuclear Medicine. All patients had melaena or enterorrhagia associated with acute anaemia. Gastroscopy, colonoscopy, enteroclysis or X-ray angiography did not detect the source of bleeding. Twenty-one patients had positive scintigraphy with in vivo labelled RBCs - 9 patients were already positive on dynamic scintigraphy, and 12 patients were positive on static images. Scintigraphy with in vivo labelled RBCs was negative in 10 patients. GI bleeding stopped spontaneously in these 10 patients with negative scintigraphy. These patients did not undergo intra-operative enteroscopy or surgery. The final diagnosis of the 21 patients with positive scintigraphy was determined in 16 patients by push-enteroscopy (6 patients), intra-operative enteroscopy (6 patients) or by surgery (4 patients). Of these 16 patients the correct place of bleeding was determined by scintigraphy with labelled RBCs in 11 (69%) patients. Final diagnoses of our 16 patients with positive scintigraphy with autological labelled RBCs were: bleeding small bowel arteriovenous malformation (6 patients), uraemic enteritis with bleeding erosions in ileum and jejunum (2 patients), Osler-Rendu- Weber disease (1 patient), pseudocyst of

    Minimal information is available on the incidence of Crimean–Congo hemorrhagic fever (CCHF) virus and hantavirus infections in Georgia. From 2008 to 2011, 537 patients with fever ≥ 38°C for ≥ 48 hours without a diagnosis were enrolled into a sentinel surveillance study to investigate the incidence of nine pathogens, including CCHF virus and hantavirus. Of 14 patients with a hemorrhagic fever syndrome, 3 patients tested positive for CCHF virus immunoglobulin M (IgM) antibodies. Two of the patients enrolled in the study had acute renal failure. These 2 of 537 enrolled patients were the only patients in the study positive for hantavirus IgM antibodies. These results suggest that CCHF virus and hantavirus are contributing causes of acute febrile syndromes of infectious origin in Georgia. These findings support introduction of critical diagnostic approaches and confirm the need for additional surveillance in Georgia. PMID:24891463

  16. Ventilation-perfusion scan in the acutely ill patient with unilateral hyperlucent lung

    A patient with a unilateral hyperlucent lung with acute respiratory complaints is presented. A ventilation-perfusion scan was performed to rule out pulmonary embolism. The perfusion scan ( [/sup 99m/TC]MAA) showed peripheral perfusion defects in the hyperlucent lung. The ventilation study (133Xe) demonstrated peripheral ventilatory defects on the single breath image in the hyperlucent lung, the filling in of these on the equilibrium view, and diffusely delayed washout in the affected lung. These findings were suggestive of the Swyer-James syndrome and critical in excluding the numerous other causes of unilateral hyperlucent lung, which are discussed. The importance of the ventilation-perfusion study (and particularly the ventilation scan) in the patient with unilateral hyperlucent lung and acute respiratory symptoms is stressed. In addition, a discussion of the Swyer-James syndrome is included

    Transfusion-related acute lung injury (TRALI) is the leading cause of transfusion-related morbidity and mortality world-wide. Although first described in 1983, it took two decades to develop consensus definitions that remain controversial. The pathogenesis of TRALI is related to the infusion of donor antibodies that recognize leukocyte antigens in the transfused host or the infusion of lipids and other biologic response modifiers that accumulate during storage or processing of blood component...

    Full Text Available Introducción: Si revisamos la literatura enfermera publicada sobre el Síndrome Coronario Agudo, cuatro son los grandes temas que han definido a nuestros estudios: los protocolos de actuación, las vías clínicas, los casos clínicos y la metodología del proceso enfermero. Casi siempre ha sido la propia enfermedad y no tanto el padecimiento del paciente la auténtica protagonista de nuestros escritos. Con nuestro presente trabajo pretendemos adentrarnos en aquellas dimensiones más subjetivas de la enfermedad, es decir, en el padecimiento y en el "sickness". Metodología: Se trata de un estudio cualitativo de tipo descriptivo en el que presentamos algunos de los datos más significativos de los relatos de nuestros pacientes con Síndrome Coronario Agudo. Resultados: los hemos agrupado en siete categorías temáticas: dolor, miedo, impacto en la familia, impacto en la actividad laboral, impacto en las actividades recreativas, impacto en el rol de cuidador y posibles causas.  Discusión: Se comparan los resultados con los de otros trabajos que han estudiado también el Síndrome Coronario Agudo desde diversas perspectivas: la sexualidad, los descriptores verbales, el dolor, y los testimonios de mujeres mexicanas que han pasado por esta misma situación.Introduction.

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

    Full Text Available Purpose. To determine the influence of physicochemical parameters on survival in metabolic acidosis (MA and acute kidney injury (AKI patients. Materials and Methods. Seventy-eight MA patients were collected and assigned to AKI or non-AKI group. We analyzed the physiochemical parameters on survival at 24 h, 72 h, 1 week, 1 month, and 3 months after AKI. Results. Mortality rate was higher in the AKI group. AKI group had higher anion gap (AG, strong ion gap (SIG, and apparent strong ion difference (SIDa values than non-AKI group. SIG value was higher in the AKI survivors than nonsurvivors and this value was correlated serum creatinine, phosphate, albumin, and chloride levels. SIG and serum albumin are negatively correlated with Acute Physiology and Chronic Health Evaluation IV scores. AG was associated with mortality at 1 and 3 months post-AKI, whereas SIG value was associated with mortality at 24 h, 72 h, 1 week, 1 month, and 3 months post-AKI. Conclusions. Whether high or low SIG values correlate with mortality in MA patients with AKI depends on its correlation with serum creatinine, chloride, albumin, and phosphate (P levels. AG predicts short-term mortality and SIG value predicts both short- and long-term mortality among MA patients with AKI.

  8. Morphine-augmented cholescintigraphy and acute a calculous cholecystitis in critically ill patients: interest and new way of interpreting

    Introduction: Acute acalculous cholecystitis (AAC) is a serious disease, difficult to diagnose in critically ill patients. The aim of the study was to evaluate the diagnostic performances of abdominal ultrasonography (US) and morphine-augmented cholescintigraphy (MC) and to improve diagnostic strategy in patients of intensive care unit (ICU) with suspected AA C. Methods: We retrospectively studied 82 consecutive ICU patients with suspected AA C. US was positive if the triad of gallbladder distension, gallbladder wall thickening and sludge was found. MC was positive if the gallbladder remained non-visualized after morphine injection. In a second time, other scintigraphic criteria of interpretation were tested, according to the visualization of the gallbladder before or after morphine administration. Treatment was decided on the basis of clinical, laboratory and imaging data. Results: The diagnosis of AAC was retained in 34 patients. US and MC had respectively for the diagnosis of AAC a sensitivity of 20.6 and 70.6%, and a specificity of 95.8 and 100%. Interpreting the MC as positive if the gallbladder remains non-visualized after morphine, as negative if it appears before, and as non-conclusive if visualized after, makes it possible to define respectively patients with high probability (100%), with low probability (7.5%) or with intermediate probability (39%) of AAC. Conclusions: MC is better than US for diagnosing AAC in critically ill patients, having in particular excellent specificity using the classical criteria of interpretation. MC must be thus performed in patients at risk for AAC, determined with clinical, laboratory and eventually echographic findings. To decrease false negative rate of MC, a probability categorical classification is proposed to improve patients' care. (author)

  9. Acute Febrile Illness and Influenza Disease Burden in a Rural Cohort Dedicated to Malaria in Senegal, 2012-2013.

    Fatoumata Diene Sarr

    Full Text Available African populations are considered to be particularly vulnerable to fever illnesses, including malaria, and acute respiratory disease, owing to limited resources and overcrowding. However, the overall burden of influenza in this context is poorly defined and incidence data for African countries are scarce. We therefore studied the fever syndrome incidence and more specifically influenza incidence in a cohort of inhabitants of Dielmo and Ndiop in Sokone district, Senegal.Daily febrile-illness data were prospectively obtained from January 2012 to December 2013 from the cohort of the villages of Dielmo and Ndiop, initially dedicated to the study of malaria. Nasopharyngeal swabs were collected from, and malaria diagnosis tests (thick blood smears carried out on, every febrile individual during clinical visits; reverse transcriptase-polymerase chain reaction was used to identify influenza viruses in the samples. Binomial negative regression analysis was used to study the relationship between the monthly incidence rate and various covariates.In Dielmo and Ndiop, the incidence of malaria has decreased, but fever syndromes remain frequent. Among the 1036 inhabitants included in the cohort, a total of 1,129 episodes of fever were reported. Influenza was present all year round with peaks in October-December 2012 and August 2013. The fever, ILI and influenza incidence density rates differed significantly between age groups. At both sites, the adjusted incidence relative risks for fever syndromes and ILI were significantly higher in the [6-24 months than other age groups: 7.3 (95%CI: [5.7-9.3] and 16.1 (95%CI: [11.1-23.3] respectively. The adjusted incidence relative risk for influenza was significantly higher for the [0-6 months than other age groups: 9.9 (95%CI: [2.9-33.6]. At both sites, incidence density rates were lowest among adults > = 50 years.In this rural setting in Senegal, influenza was most frequent among the youngest children. Preventive

  10. Host Biomarkers for Distinguishing Bacterial from Non-Bacterial Causes of Acute Febrile Illness: A Comprehensive Review

    Kapasi, Anokhi J.; Dittrich, Sabine; González, Iveth J.; Rodwell, Timothy C.

    2016-01-01

    Background In resource limited settings acute febrile illnesses are often treated empirically due to a lack of reliable, rapid point-of-care diagnostics. This contributes to the indiscriminate use of antimicrobial drugs and poor treatment outcomes. The aim of this comprehensive review was to summarize the diagnostic performance of host biomarkers capable of differentiating bacterial from non-bacterial infections to guide the use of antibiotics. Methods Online databases of published literature were searched from January 2010 through April 2015. English language studies that evaluated the performance of one or more host biomarker in differentiating bacterial from non-bacterial infection in patients were included. Key information extracted included author information, study methods, population, pathogens, clinical information, and biomarker performance data. Study quality was assessed using a combination of validated criteria from the QUADAS and Lijmer checklists. Biomarkers were categorized as hematologic factors, inflammatory molecules, cytokines, cell surface or metabolic markers, other host biomarkers, host transcripts, clinical biometrics, and combinations of markers. Findings Of the 193 citations identified, 59 studies that evaluated over 112 host biomarkers were selected. Most studies involved patient populations from high-income countries, while 19% involved populations from low- and middle-income countries. The most frequently evaluated host biomarkers were C-reactive protein (61%), white blood cell count (44%) and procalcitonin (34%). Study quality scores ranged from 23.1% to 92.3%. There were 9 high performance host biomarkers or combinations, with sensitivity and specificity of ≥85% or either sensitivity or specificity was reported to be 100%. Five host biomarkers were considered weak markers as they lacked statistically significant performance in discriminating between bacterial and non-bacterial infections.

  11. Long-term sequelae of severe acute kidney injury in the critically ill patient without comorbidity: a retrospective cohort study.

    Gijs Fortrie

    Full Text Available Acute kidney injury (AKI necessitating renal replacement therapy (RRT is associated with high mortality and increased risk for end stage renal disease. However, it is unknown if this applies to patients with a preliminary unremarkable medical history. The purpose of this study was to describe overall and renal survival in critically ill patients with AKI necessitating RRT stratified by the presence of comorbidity.A retrospective cohort study was performed, between 1994 and 2010, including all adult critically ill patients with AKI necessitating RRT, stratified by the presence of comorbidity. Logistic regression, survival curve and cox proportional hazards analyses were used to evaluate overall and renal survival. Standardized mortality rate (SMR analysis was performed to compare long-term survival to the predicted survival in the Dutch population.Of the 1067 patients included only 96(9.0% had no comorbidity. Hospital mortality was 56.6% versus 43.8% in patients with and without comorbidity, respectively. In those who survived hospitalization 10-year survival was 45.0% and 86.0%, respectively. Adjusted for age, sex and year of treatment, absence of comorbidity was not associated with hospital mortality (OR=0.74, 95%-CI=0.47-1.15, while absence of comorbidity was associated with better long-term survival (adjusted HR=0.28, 95%-CI = 0.14-0.58. Compared to the Dutch population, patients without comorbidity had a similar mortality risk (SMR=1.6, 95%-CI=0.7-3.2, while this was increased in patients with comorbidity (SMR=4.8, 95%-CI=4.1-5.5. Regarding chronic dialysis dependency, 10-year renal survival rates were 76.0% and 92.9% in patients with and without comorbidity, respectively. Absence of comorbidity was associated with better renal survival (adjusted HR=0.24, 95%-CI=0.07-0.76.While hospital mortality remains excessively high, the absence of comorbidity in critically ill patients with RRT-requiring AKI is associated with a relative good long

St. Luke’s Episcopal Hospital/Texas Heart Institute, Houston, Texas, USAAbstract: Clevidipine is a new calcium channel blocker of the dihydropyridine class that is characterized by its ultra-short onset of action, vascular selectivity, small volume of distribution and extremely high clearance that coupled together result in an extremely short half-life of approximately 1 minute therefore permitting a rapid titration to the desired effect. Structurally similar to other dihydropyridines, clevidipine has an extra ester link that allows its rapid hydrolization to its inactive carboxylic acid metabolite in blood and extravascular tissues. Clevidipine’s metabolites are then primarily eliminated through urine and fecal pathways. Clevidipine does not affect cytochrome P450 (CYP enzymes and no clinically significant drug interactions have been determined. In trials like the ESCAPE trials, ECLIPSE, and VELOCITY, clevidipine demonstrated a significant improvement in the management of acute hypertension when compared to placebo as shown in both ESCAPE trials. The ECLIPSE trial compared clevidipine to other drugs currently used in the management of acute hypertension, such as sodium nitroprusside, nitroglycerine and nicardipine; clevidipine was superior to all three agents; in providing blood pressure support, safety and tolerability clevidipine also showed a significant reduction in mortality rate (4.7% vs 1.7%, P = 0.0445 when compared to sodium nitroprusside. In the VELOCITY trial clevidipine demonstrated a reduction in blood pressure of 6

    This study aimed to determine the prevalence of acute lower respiratory illness and to identify associated factors among children less than five years of age in the city of Rio Grande, southern Brazil. Using a cross-sectional survey, a standardized household questionnaire was applied to mothers or guardians. Information was collected on household conditions, socioeconomic status, and parental smoking. Prenatal care attendance, nutritional status, breastfeeding pattern, and use of health services for the children were also investigated. Data analysis was based on prevalence ratios and logistic regression, using a conceptual framework. Among 771 children studied, 23.9% presented acute lower respiratory illness. The main risk factors were previous episodes of acute lower respiratory infection or wheezing, crowding, maternal schooling less than five years, monthly family income less than US$ 200, four or more people per room, asthma in family members, and maternal smoking. Mothers 30 years or older were identified as a protective factor. These results can help define specific measures to reduce morbidity and mortality due to acute lower respiratory illness in this setting. PMID:18545768

    Full Text Available Respiratory Diseases are public health concern worldwide. The diseases have been associated with air pollution especially indoor air pollution from biomass fuel burning in developing countries. However, researches on pollution levels and on association of respiratory diseases with biomass fuel pollution are limited. A study was therefore undertaken to characterize the levels of pollutants in biomass fuel using homes and examine the association between biomass fuel smoke exposure and Acute Respiratory Infection (ARI disease in Nianjema village in Bagamoyo, Tanzania. Pollution was assessed by measuring PM10, NO2, and CO concentrations in kitchen, living room and outdoors. ARI prevalence was assessed by use of questionnaire which gathered health information for all family members under the study. Results showed that PM10, NO2, and CO concentrations were highest in the kitchen and lowest outdoors. Kitchen concentrations were highest in the kitchen located in the living room for all pollutants except CO. Family size didn’t have effect on the levels measured in kitchens. Overall ARI prevalence for cooks and children under age 5 making up the exposed group was 54.67% with odds ratio (OR of 5.5; 95% CI 3.6 to 8.5 when compared with unexposed men and non-regular women cooks. Results of this study suggest an association between respiratory diseases and exposure to domestic biomass fuel smoke, but further studies with improved design are needed to confirm the association.

    2010-02-01

    Full Text Available Abstract Background Chikungunya virus (CHIKV is responsible for major epidemics worldwide. Autochthonous cases were recently reported in several European countries. Acute infection is thought to be monophasic. However reports on chronic pain related to CHIKV infection have been made. In particular, the fact that many of these patients do not respond well to usual analgesics suggests that the nature of chronic pain may be not only nociceptive but also neuropathic. Neuropathic pain syndromes require specific treatment and the identification of neuropathic characteristics (NC in a pain syndrome is a major step towards pain control. Methods We carried out a cross-sectional study at the end of the major two-wave outbreak lasting 17 months in Réunion Island. We assessed pain in 106 patients seeking general practitioners with confirmed infection with the CHIK virus, and evaluated its impact on quality of life (QoL. Results The mean intensity of pain on the visual-analogical scale (VAS was 5.8 ± 2.1, and its mean duration was 89 ± 2 days. Fifty-six patients fulfilled the definition of chronic pain. Pain had NC in 18.9% according to the DN4 questionnaire. Conversely, about two thirds (65% of patients with NC had chronic pain. The average pain intensity was similar between patients with or without NC (6.0 ± 1.7 vs 6.1 ± 2.0. However, the total score of the Short Form-McGill Pain Questionnaire (SF-MPQ(15.5 ± 5.2 vs 11.6 ± 5.2; p Conclusions There exists a specific chronic pain condition associated to CHIKV. Pain with NC seems to be associated with more aggressive clinical picture, more intense impact in QoL and more challenging pharmacological treatment.

    2013-01-01

    Full Text Available In a multicenter observational cohort of patients-admitted to intensive care units (ICU, we assessed whether creatinine elevation prior to dialysis initiation in acute kidney injury (AKI-D further discriminates risk-adjusted mortality. AKI-D was categorized into four groups (Grp based on creatinine elevation after ICU admission but before dialysis initiation: Grp I  > 0.3 mg/dL to <2-fold increase, Grp II ≥2 times but <3 times increase, Grp III ≥3-fold increase in creatinine, and Grp IV none or <0.3 mg/dl increase. Standardized mortality rates (SMR were calculated by using a validated risk-adjusted mortality model and expressed with 95% confidence intervals (CI. 2,744 patients developed AKI-D during ICU stay; 36.7%, 20.9%, 31.2%, and 11.2% belonged to groups I, II, III, and IV, respectively. SMR showed a graded increase in Grp I, II, and III (1.40 (95% CI, 1.29–1.42, 1.84 (1.66–2.04, and 2.25 (2.07–2.45 and was 0.98 (0.78–1.20 in Grp IV. In ICU patients with AKI-D, degree of creatinine elevation prior to dialysis initiation is independently associated with hospital mortality. It is the lowest in those experiencing minor or no elevations in creatinine and may represent reversible fluid-electrolyte disturbances.

    Information on the infectious causes of undifferentiated acute febrile illness (AFI) in Georgia is essential for effective treatment and prevention. In May 2008, a hospital-based AFI surveillance was initiated at six hospitals in Georgia. Patients aged ≥ 4 years with fever ≥ 38°C for ≥ 48 hours were eligible for surveillance. Blood culture and serologic testing were conducted for Leptospira spp., Brucella spp., West Nile virus (WNV), Crimean-Congo hemorrhagic fever virus, Coxiella burnetii, tick-borne encephalitis virus (TBEV), hantavirus, Salmonella enterica serovar Typhi (S. Typhi), and Rickettsia typhi. Of 537 subjects enrolled, 70% were outpatients, 54% were males, and the mean age was 37 years. Patients reported having fatigue (89%), rigors (87%), sweating (83%), pain in joints (49%), and sleep disturbances (42%). Thirty-nine (7%) patients were seropositive for R. typhi, 37 (7%) for Brucella spp., 36 (7%) for TBEV, 12 (2%) for Leptospira spp., 10 (2%) for C. burnetii, and three (0.6%) for S. Typhi. None of the febrile patients tested positive for WNV antibodies. Of the patients, 73% were negative for all pathogens. Our results indicate that most of the targeted pathogens are present in Georgia, and highlight the importance of enhancing laboratory capacity for these infectious diseases. PMID:26438032

    Full Text Available Between 2007 and 2013, there were 685 events with evidence of a relationship between pesticide exposure and acute illness/injury among persons less than 18 years old in North Carolina (United States. Median age of children affected was 4.3 years (range: 0.2–17.9. Distribution by gender was similar across all age groups. One fatality and four high severity events were observed. The greatest proportion (42% of events had ocular exposures, followed by dermal (25% and inhalation (18% exposures. When more than one route of exposure occurred, dermal and ocular routes were the most common (46%. Almost all events took place indoors and 32 events involved contact with pets. Insecticides (53% and insect repellants (31% were the most frequent agents contributing to these events. Manual application of pesticides contributed to the greatest number of events (25%, while application through a pressurized can and use of a trigger pump were involved in 21% and 15% of events, respectively. Additional contributors were due to inappropriate storage of pesticides and improper use of the pesticide. These contributing factors can be removed or minimized if pesticides are stored outside the residence or out of the reach of children and pets, and adequate ventilation is ensured whenever pesticides are applied.

The only identifiable scale initially developed for pediatric application has been the Canadian acute respiratory illness and flu scale (CARIFS. The aim of our trial was to adapt the English version of the CARIFS to the Ukrainian language.Materials and methods: We performed forward and backward translation of the original version of the CARIFS according to the recommended standard. Then, the final CARIFS-based Ukrainian questionnaires were given to 149 caregivers whose 3–12 years old children suffered from ARTI. The questionnaires were completed twice by a caregiver 3–6 hours apart and once by a physician just after the second completion by a caregiver. The database was analyzed to assess the consistency (the Cronbach's α coefficient, sensitivity (the standardized response mean; the effect size, reliability (test–retest analysis, and validity (Pearson's correlation of the CARIFS in the Ukrainian language.Results: The backward translation of the Ukrainian version of the CARIFS demonstrated its good correspondence to the English version. The Cronbach’s α coefficient was 0.805, and item to total correlation coefficients varied from 0.185 to 0.665. The standardized response mean was 1.73, and the effect size was 2.50 suggesting good sensitivity of the scale.

    A. Ríos

    2006-03-01

    Full Text Available Introduction: lower gastrointestinal hemorrhage (LGIH is generally self-limiting, and the most frequent etiologies are located at colonic level. The objective here is to analyze the diagnostic and therapeutic handling of acute LGIH when its etiology was located in the small intestine. Patients and methods: between 1975 and March 2002, 12 acute cases of LGIH originating in the small intestine were admitted to our service. All consulted the hospital with acute rectorrhage, requiring a transfusion of at least 3 units of concentrated red blood cells. The mean age was 54 ± 21 years, 58% were women, and 83% had experienced previous episodes of LGIH. Results: in eleven cases (92% an urgent lower and upper endoscopy was performed without locating the source of bleeding. An arteriography was indicated in 7 patients (58%, which located the bleeding origin in 5 of them. In two cases a scintigraphy was performed, showing a Meckel's diverticulum in one patient and a normal image in another. All were operated on; in 8 cases (67%, surgery was urgent; in 9 cases, a tumor was found, and in three additional patients, a case of Meckel's diverticulum was found, with a resection being carried out for all lesions. Histology showed a leiomyoma in 7 cases, a Meckel's diverticulum in 3 cases, a leiomyoblastoma in 1, and an angioma in the remaining case. After a mean follow-up of 132 ± 75 months, the leiomyoblastoma resulted in death, and there was a relapse in the case of angioma, which was successfully embolized with interventional radiology. Conclusions: acute LGIH originating in the small intestine should be considered a possible etiology when digestive endoscopy does not locate the source of bleeding, with arteriography being a useful diagnostic technique for bleeding localization. Surgery is the definitive treatment - it confirms the etiology and rules out the presence of malignancy.Introducción: la hemorragia digestiva baja (HDB es generalmente autolimitada y

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

  11. Localization of the acute lower gastrointestinal hemorrhage in vivo-in vitro labeling of red blood cells with sup(99m)Tc

    For the detection and localization of acute lower gastrointestinal hemorrhage in vivo-in vitro labeling of red blood cells with sup(99m)Tc and sup(99m)Tc sulfur colloid has been sugested. The procedure for labeling RBC with sup(99m)Tc consisted in injecting IV 1 mg of ClSn; 20 minutes after injection of tin 10 cc of blood were withdrawn in a syringe containing 20 mCi of sup(99m)Tc; this was incubated for 10 minutes and then injected IV. Scintigraphy of the abdominal cavity was done in supine position and performed with a large field gamma camera with a parallel hole-low energy colimator. Computer adquisition of images was started 5 minutes after RBC injection and made at the rate of one enery 5 minutes for 45 minutes. 14 patients were studied divided in: a) control: 6 patients. b) with active gastrointestinal hemorrhage: 4 patients had positive scintigraphy. The hemorrhage was documented with superior mesenteric arteriography, endoscopy and/or necropsy. The sensitivity was 100%. In 4 out of 14 patients scintigraphy with sup(99m)Tc RBC compared with simultaneous sup(99m)Tc sulfur colloid demonstrated that all patients with positive sup(99m)Tc RBC had also positive sup(99m)Tc sulfur colloid scintigraphy. c) without active gastrointestinal hemorrhage: all of them had negative scintigraphy (specificity 100%). Abdominal scintigraphy with sup(99m)Tc RBC or sulfur colloid are both sensitive for detection and localization of lower gastrointestinal bleeding and the negative study suggests the absence of active hemorrhage. It is suggested that the sup(99m)Tc sulfur colloid scintigraphy should be the initial procedure to study these patients and abdominal arteriography should be performed only in patients with positive abdominal scintigraphy.

    2014-01-01

    Background There is no internationally recognized outcome measure for the assessment of acute respiratory tract infections (ARTIs) in children. The only identifiable scale initially developed for pediatric application has been the Canadian acute respiratory illness and flu scale (CARIFS). The aim of our trial was to adapt the English version of the CARIFS to the Ukrainian language. Materials and methods We performed forward and backward translation of the original version of the CARIFS according to the recommended standard. Then, the final CARIFS-based Ukrainian questionnaires were given to 149 caregivers whose 3–12 years old children suffered from ARTI. The questionnaires were completed twice by a caregiver 3–6 hours apart and once by a physician just after the second completion by a caregiver. The database was analyzed to assess the consistency (the Cronbach’s α coefficient), sensitivity (the standardized response mean; the effect size), reliability (test–retest analysis), and validity (Pearson’s correlation) of the CARIFS in the Ukrainian language. Results The backward translation of the Ukrainian version of the CARIFS demonstrated its good correspondence to the English version. The Cronbach’s α coefficient was 0.805, and item to total correlation coefficients varied from 0.185 to 0.665. The standardized response mean was 1.73, and the effect size was 2.50 suggesting good sensitivity of the scale. In the test–retest reliability analysis of 99 questionnaires, the median CARIFS score for the first and the second measurement was 19.0 (interquartile range [IQR]: 14.5–25.0) and 19.0 (IQR: 15.0–25.0), respectively, with a median change of 0.0 (IQR: −1.0 to 0.0, P=0.996). The Pearson’s correlation coefficient between the CARIFS score completed by a responder and a physician was 0.832 (P=0.004). Conclusion The Ukrainian version of the CARIFS-based English questionnaire proved to be a consistent, sensitive, reliable, and valid instrument in the

    2015-01-01

    The replacement of “presumptive treatment for malaria” by “test before treat” strategies for the management of febrile illness is raising awareness of the importance of knowing more about the causes of illness in children who are suspected to have malaria but return a negative parasitological test. The most common cause of non-malarial febrile illness (NMFI) in African children is respiratory tract infection. Whilst the bacterial causes of NMFI are well known, the increasing use of sensitive ...

  14. Association of a XRCC3 polymorphism and rectum mean dose with the risk of acute radio-induced gastrointestinal toxicity in prostate cancer patients

    Background and purpose: We have performed a case–control study among prostate cancer patients treated with three-dimensional conformational radiotherapy (3D-CRT) in order to investigate the association between single nucleotide polymorphisms (SNPs), treatment and patient features with gastrointestinal and genitourinary acute toxicity. Material and methods: A total of 698 patients were screened for 14 SNPs located in the ATM, ERCC2, LIG4, MLH1 and XRCC3 genes. Gastrointestinal and genitourinary toxicities were recorded prospectively using the Common Terminology Criteria for Adverse Events v3.0. Results: The XRCC3 SNP rs1799794 (G/G OR = 5.65; 95% CI: 1.95–16.38; G/A OR = 2.75; 95% CI: 1.25–6.05; uncorrected p-value = 2.8 × 10−03; corrected p-value = 0.03; FDR q-value = 0.06) as well as the mean dose received by the rectum (OR = 1.06; 95% CI: 1.02–1.1; uncorrected p-value = 2.49 × 10−03; corrected p-value = 0.03; FDR q-value = 0.06) were significantly associated with gastrointestinal toxicity after correction for multiple testing. Those patients who undergone previous prostatectomy were less prone to develop genitourinary toxicity (OR = 0.38; 95% CI: 0.18–0.71; uncorrected p-value = 4.95 × 10−03; corrected p-value = 0.03; FDR q-value = 0.08). Our study excludes the possibility of a >2-fold risk increase in genitourinary acute toxicity being due to rs1801516 ATM SNP, the rs1805386 and rs1805388 LIG4 markers, as well as all the SNPs evaluated in the ERCC2, MLH1 and XRCC3 genes. Conclusions: The XRCC3 rs1799794 SNP and the mean dose received by the rectum are associated with the development of gastrointestinal toxicity after 3D-CRT.

  16. A Sporadic Small Jejunal GIST Presenting with Acute Lower Gastrointestinal Hemorrhage: A Review of the Literature and Management Guidelines.

    Govindaraj, Sridar; Dias, Brendan Hermenigildo; Gautham, S L

    2015-04-01

    Gastrointestinal stromal tumors (GISTs) represent the majority of primary nonepithelial neoplasms of the digestive tract, most frequently expressing the KIT protein detected by immunohistochemical staining for the CD117 antigen. Jejunal GISTs account for approximately 10 % of GISTs. Patients usually present with abdominal discomfort. Jejunal GISTs may cause symptoms secondary to obstruction or hemorrhage. Pressure necrosis and ulceration of the overlying mucosa may cause gastrointestinal bleeding, and patients who experience significant blood loss may suffer from malaise and fatigue. Literature has classified small-bowel GISTs on the basis of size, and various established guidelines have advised conservative management of small jejunal GISTs (lower gastrointestinal hemorrhage in a 50-year-old postmenopausal woman necessitating an emergency laparotomy to control the bleed. The management of very small (<2 cm) small-bowel GISTs is controversial. While guidelines are primarily based on the risk of malignancy in GISTs, no guideline predicting the risk of complications in small-bowel GISTs exists. Hence, these tumors should be removed even if incidentally detected. PMID:25972676

    2012-01-01

    Full Text Available Objective. Sublingual microcirculatory alterations are associated with an adverse prognosis in several critical illness subgroups. Up to now, single-center studies have reported on sublingual microcirculatory alterations in ICU patient subgroups, but an extensive evaluation of the prevalence of these alterations is lacking. We present the study design of an international multicenter observational study to investigate the prevalence of microcirculatory alterations in critically ill: the Microcirculatory Shock Occurrence in Acutely ill Patients (microSOAP. Methods. 36 ICU’s worldwide have participated in this study aiming for inclusion of over 500 evaluable patients. To enable communication and data collection, a website, an Open Clinica 3.0 database, and image uploading software have been designed. A one-session assessment of the sublingual microcirculation using Sidestream Dark Field imaging and data collection on patient characteristics has been performed in every ICU patient >18 years, regardless of underlying disease. Statistical analysis will provide insight in the prevalence and severity of sublingual alterations, its relation to systemic hemodynamic variables, disease, therapy, and outcome. Conclusion. This study will be the largest microcirculation study ever performed. It is expected that this study will also establish a basis for future studies related to the microcirculation in critically ill.

    2016-01-01

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

  19. Safety and efficacy of thromboprophylaxis with fondaparinux in elderly acutely ill medical patients with renal impairment: a retrospective single center study

    Federico Silvestri

    2013-12-01

    Full Text Available The majority of acutely ill medical patients are elderly with some degree of renal impairment. In this setting, venous thromboembolism (VTE is one of the leading causes of morbidity and mortality and, to reduce this risk, a correct thromboprophylaxis is needed. The aim of this single center retrospective study was to assess the safety and efficacy of fondaparinux in elderly acutely ill medical patients with renal impairment. All patients aged 60 years or over, bedridden for at least four days, with a creatinine clearance (CrCl of 50 mL/min or under, and who had received fondaparinux during hospitalization were evaluated and followed for up to 90 days after discharge. A total of 125 patients were evaluated (34.4% males; median age was 83.0 years. Median duration of thromboprophylaxis was 9.0 days. Forty-one (32.8% patients were treated with fondaparinux 1.5 mg daily, 84 (67.2% with 2.5 mg daily. Inappropriately high doses of fondaparinux were used in 77 patients with CrCl 20-50 mL/min, in 12 patients with CrCl below 20 mL/min, in 14 patients with prothrombin time (PT ratio over 1.2, in 8 patients with PT ratio over 1.5, and in 3 patients with thrombocytopenia. No episodes of VTE or of major bleeding were recorded while there were 6 episodes (2.4% of minor bleeding. Both dosages of fondaparinux showed similar safety and efficacy. Twenty-six patients (20.8% died; no cause of death was related to fondaparinux. In conclusion, in elderly acutely ill hospitalized medical patients with renal impairment, prophylaxis with fondaparinux 2.5 or 1.5 mg daily is safe and effective in preventing VTE without increasing bleeding risk.

  4. Risk Factors for Development of Acute Kidney Injury in Critically Ill Patients: A Systematic Review and Meta-Analysis of Observational Studies

    Rodrigo Cartin-Ceba

    2012-01-01

    Full Text Available Background. Acute kidney injury (AKI is a frequent complication of critically ill patients. The impact of different risk factors associated with this entity in the ICU setting is unknown. Objectives. The purpose of this research was to assess the risk factors associated with the development of AKI in critically ill patients by meta-analyses of observational studies. Data Extraction. Two reviewers independently and in duplicate used a standardized form to collect data from published reports. Authors were contacted for missing data. The Newcastle-Ottawa scale assessed study quality. Data Synthesis. Data from 31 diverse studies that enrolled 504,535 critically ill individuals from a wide variety of ICUs were included. Separate random-effects meta-analyses demonstrated a significantly increased risk of AKI with older age, diabetes, hypertension, higher baseline creatinine, heart failure, sepsis/systemic inflammatory response syndrome, use of nephrotoxic drugs, higher severity of disease scores, use of vasopressors/inotropes, high risk surgery, emergency surgery, use of intra-aortic balloon pump, and longer time in cardiopulmonary bypass pump. Conclusion. The best available evidence suggests an association of AKI with 13 different risk factors in subjects admitted to the ICU. Predictive models for identification of high risk individuals for developing AKI in all types of ICU are required.

  5. A prospective randomized controlled trial to study the role of sulfasalazine in prevention of acute gastrointestinal toxicity associated with concurrent chemoradiation in carcinoma cervix

    2013-01-01

    Full Text Available Background: The primary aim of the study was to evaluate the effectiveness of sulfasalazine in reducing the incidence of acute radiation-induced enteritis in carcinoma cervix patients receiving pelvic external beam radiotherapy along with concurrent cisplatin-based chemotherapy. Materials and Methods: Between November 2011 and July 2012 a total of 98 patients of locoregionally advanced carcinoma of cervix (49 each in study and control arms were enrolled in this study. Patients in both the arms were treated with whole pelvis external beam radiotherapy with total dose of 50 Gy in conventional fractionation. Along with this inj. cisplatin was given concurrently at the dose of 40 mg/m 2 of body surface area every week during radiation for 5 weeks. Concurrent chemoradiation was followed by brachytherapy after a gap of 2 weeks. Patients in the study arm also received tablet sulfasalazine 1,000 mg orally twice daily from the day of starting of radiotherapy to 1 week after completion of treatment. Weekly follow-up of all patients to assess acute toxicities was done using common toxicity criteria version 4.0 (CTC v4.0 toxicity scores. Data analysis was carried out by SPSS version 20.0 software. Results: Incidence of grade II or higher grade, lower gastrointestinal toxicity was 19.14% (09/47 in study arm and 41.66% (20/48 in control arm which was statistically significant (P = 0.017. Conclusion: The study shows that sulfasalazine can significantly reduce the acute radiation-induced diarrhea (ARID in patients undergoing whole pelvis external beam radiotherapy for carcinoma cervix. The drug is safe, cheap, and readily available.

  6. Early and late-onset acute GvHD following hematopoietic cell transplantation: CT features of gastrointestinal involvement with clinical and pathological correlation

    Objective: With the introduction of non-myeloablative hematopoietic cell transplantation, acute graft-versus-host-disease (GvHD) is frequently observed beyond the traditional 100 days cut-off. The aim of this study was to describe and compare CT features of gastrointestinal early and late-onset GvHD and to correlate findings with clinical and pathology grading. Subjects and methods: Abdominal CT scans were obtained in 20 patients with early and 15 with late-onset GvHD. Examinations were assessed for intestinal and extraintestinal abnormalities and findings compared between the two subgroups of GvHD. Distinct CT abnormalities as well as a CT-score integrating multiple pathologies were correlated with gut, clinical or pathology grading. Results: Frequent intestinal abnormalities included wall thickening, abnormal enhancement, and excessive fluid-filling (94%, 89%, and 94%). 86% of patients showed concomitant small and large bowel involvement. A discontinuous distribution was observed in 54%. Bile tract abnormality was the most common extra-intestinal finding (74%). The distribution of pathologies was equal between subgroups of early or late-onset disease. Wall thickening and mucosal attenuation in non-enhanced scans were significantly related to clinical and pathology scores (P ≤ 0.018). Number of abnormal segments, small bowel dilatation, engorgement of the vasa recta, mesenteric fat stranding and ascites were linked to clinical grading (P ≤ 0.019). A CT-score integrating multiple abnormalities was correlated to gut, overall clinical and pathology grading (r = 0.64, 0.57, 0.50). Conclusion: CT morphology of acute GvHD is independent of its time of onset and, thus, facilitates differential diagnosis of late-onset acute GvHD. Correlation of CT morphology with clinical and pathological grading is important in terms of prognosis and may help guiding the therapeutic approach.

  7. Normal Tissue Complication Probability Analysis of Acute Gastrointestinal Toxicity in Cervical Cancer Patients Undergoing Intensity Modulated Radiation Therapy and Concurrent Cisplatin

    Purpose: To test the hypothesis that increased bowel radiation dose is associated with acute gastrointestinal (GI) toxicity in cervical cancer patients undergoing concurrent chemotherapy and intensity-modulated radiation therapy (IMRT), using a previously derived normal tissue complication probability (NTCP) model. Methods: Fifty patients with Stage I–III cervical cancer undergoing IMRT and concurrent weekly cisplatin were analyzed. Acute GI toxicity was graded using the Radiation Therapy Oncology Group scale, excluding upper GI events. A logistic model was used to test correlations between acute GI toxicity and bowel dosimetric parameters. The primary objective was to test the association between Grade ≥2 GI toxicity and the volume of bowel receiving ≥45 Gy (V45) using the logistic model. Results: Twenty-three patients (46%) had Grade ≥2 GI toxicity. The mean (SD) V45 was 143 mL (99). The mean V45 values for patients with and without Grade ≥2 GI toxicity were 176 vs. 115 mL, respectively. Twenty patients (40%) had V45 >150 mL. The proportion of patients with Grade ≥2 GI toxicity with and without V45 >150 mL was 65% vs. 33% (p = 0.03). Logistic model parameter estimates V50 and γ were 161 mL (95% confidence interval [CI] 60–399) and 0.31 (95% CI 0.04–0.63), respectively. On multivariable logistic regression, increased V45 was associated with an increased odds of Grade ≥2 GI toxicity (odds ratio 2.19 per 100 mL, 95% CI 1.04–4.63, p = 0.04). Conclusions: Our results support the hypothesis that increasing bowel V45 is correlated with increased GI toxicity in cervical cancer patients undergoing IMRT and concurrent cisplatin. Reducing bowel V45 could reduce the risk of Grade ≥2 GI toxicity by approximately 50% per 100 mL of bowel spared.

  8. Acute gastrointestinal and genitourinary toxicity of image-guided intensity modulated radiation therapy for prostate cancer using a daily water-filled endorectal balloon

    Our purpose was to report acute gastrointestinal (GI) and genitourinary (GU) toxicity rates for prostate cancer patients undergoing image-guided intensity modulated radiation therapy (IG-IMRT) with a daily endorectal water-filled balloon (ERBH2O), and assess associations with planning parameters and pretreatment clinical characteristics. The first 100 patients undergoing prostate and proximal seminal vesicle IG-IMRT with indexed-lumen 100 cc ERBH2O to 79.2 Gy in 1.8 Gy fractions at our institution from 12/2008- 12/2010 were assessed. Pretreatment characteristics, organ-at-risk dose volume histograms, and maximum GU and GI toxicities (CTCAE 3.0) were evaluated. Logistic regression models evaluated univariate association between toxicities and dosimetric parameters, and uni- and multivariate association between toxicities and pretreatment characteristics. Mean age was 68 (range 51–88). Thirty-two, 49, and 19 patients were low, intermediate, and high-risk, respectively; 40 received concurrent androgen deprivation. No grade 3 or greater toxicities were recorded. Maximum GI toxicity was grade 0, 1, and 2 in 69%, 23%, and 8%, respectively. Infield (defined as 1 cm above/below the CTV) rectal mean/median doses, D75, V30, and V40 and hemorrhoid history were associated with grade 2 GI toxicity (Ps < 0.05). Maximum acute GU toxicity was grade 0, 1, and 2 for 17%, 41%, and 42% of patients, respectively. Infield bladder V20 (P = 0.03) and pretreatment International Prostate Symptom Scale (IPSS) (P = 0.003) were associated with grade 2 GU toxicity. Prostate IG-IMRT using a daily ERBH2O shows low rates of acute GI toxicity compared to previous reports of air-filled ERB IMRT when using stringent infield rectum constraints and comparable GU toxicities

  9. Inherent illnesses and attacks: an ethnographic study of interpretations of childhood Acute Respiratory Infections (ARIs in Manhiça, southern Mozambique

    Pell Christopher

    2011-07-01

    Full Text Available Abstract Background Pneumonia is a leading cause of childhood hospitalisation and child mortality in Africa. This study explores local interpretations of Acute Respiratory Infections (ARIs, focusing on caretakers of children under five in the context of hospital care seeking. Methods The study took place in Manhiça, southern Mozambique and used Focused Ethnographic Study tools (FES including field exercises and interviews. Results Understandings of terms used to describe ARIs differed between caretakers and hospital staff. Children's sicknesses that hospital staff diagnosed as ARIs were interpreted by caretakers as intermittent "attacks" of xifuva, a permanent, inherent and incurable chest illness. Caretakers thought that it was possible to manage and treat the attacks, which were caused by immediate natural factors such as food or the weather, but not the underlying illness, which was seen as having more indirect and social causes. Explanations of illness could not be neatly separated into pluralistic categories, but were characterised by syncretism, with "lay" and "biomedical" terms and concepts intermingling in practical care-seeking interactions between caretakers and health staff. Conclusions Health promotion should take into account the syncretism involved in explanations of ARIs in the context of practical care seeking for children. In doing so, it should draw upon lay interpretations and terminologies in order to stress the importance of seeking hospital care for all xifuva-type illnesses as well as seeking care for any subsequent attacks of an already diagnosed xifuva. However, this should be undertaken with awareness that the meanings of the terms used in practical care-seeking interactions may change over time. Health communication about ARIs should therefore be ongoing and evidence-based, even if ARIs appear to be well understood.

    Local prevalences of individual diseases influence the prioritization of the differential diagnoses of a clinical syndrome of acute undifferentiated febrile illness (AFI). This study was conducted in order to delineate the aetiology of AFI that present to a tertiary hospital in southern India and to describe disease-specific clinical profiles. An 1-year prospective, observational study was conducted in adults (age >16 years) who presented with an undifferentiated febrile illness of duration 5-21 days, requiring hospitalization. Blood cultures, malarial parasites and febrile serology (acute and convalescent), in addition to clinical evaluations and basic investigations were performed. Comparisons were made between each disease and the other AFIs. A total of 398 AFI patients were diagnosed with: scrub typhus (47.5%); malaria (17.1%); enteric fever (8.0%); dengue (7.0%); leptospirosis (3.0%); spotted fever rickettsiosis (1.8%); Hantavirus (0.3%); alternate diagnosis (7.3%); and unclear diagnoses (8.0%). Leucocytosis, acute respiratory distress syndrome, aseptic meningitis, mild serum transaminase elevation and hypoalbuminaemia were independently associated with scrub typhus. Normal leukocyte counts, moderate to severe thrombocytopenia, renal failure, splenomegaly and hyperbilirubinaemia with mildly elevated serum transaminases were associated with malaria. Rash, overt bleeding manifestations, normal to low leukocyte counts, moderate to severe thrombocytopenia and significantly elevated hepatic transaminases were associated with dengue. Enteric fever was associated with loose stools, normal to low leukocyte counts and normal platelet counts. It is imperative to maintain a sound epidemiological database of AFIs so that evidence-based diagnostic criteria and treatment guidelines can be developed. PMID:20870680

    Full Text Available OBJECTIVE: To compare the renal outcome in patients submitted to two different regimens of glycemic control, using the RIFLE criteria to define acute kidney injury. INTRODUCTION: The impact of intensive insulin therapy on renal function outcome is controversial. The lack of a criterion for AKI definition may play a role on that. METHODS: Included as the subjects were 228 randomly selected, critically ill patients engaged in intensive insulin therapyor in a carbohydrate-restrictive strategy. Renal outcome was evaluated through the comparison of the last RIFLE score obtained during the ICU stay and the RIFLE score at admission; the outcome was classified as favorable, stable or unfavorable. RESULTS: The two groups were comparable regarding demographic data. AKI developed in 52% of the patients and was associated with a higher mortality (39.4% compared with those who did not have AKI (8.2% (p60, acute kidney injury and hypoglycemia were risk factors for mortality. CONCLUSION: Intensive insulin therapy and a carbohydrate-restrictive strategy were comparable regarding the incidence of acute kidney injury evaluated using RIFLE criteria.

    Influenza-like illness causes substantial morbidity and mortality. Air pollution has already been linked to many health issues, and increasing evidence in recent years supports an association between air pollution and respiratory infections. It is a pioneer study in China to quantify the effects of air pollution on influenza-like illness. This study used wavelet coherence analysis and generalized additive models to explore the potential association between air pollution (including particulate matter with aerodynamic diameter ≦2.5 μm (PM2.5), particulate matter with aerodynamic diameter ≦10 μm (PM10) and nitrogen dioxide (NO2)) and influenza-like illness (a total of 59860 cases) in Nanjing, China from January 1, 2013 to December 31, 2013. The average concentrations of PM2.5, PM10 and NO2 were 77.37 μg/m(3), 135.20 μg/m(3) and 55.80 μg/m(3). An interquartile range increase in PM2.5 concentration was associated with a 2.99% (95% confidence interval (CI): 1.64%, 4.36%) increase in daily influenza-like cases on the same day, while the corresponding increase in NO2 was associated with a 3.77% (95% CI: 2.01%, 5.56%) increase in daily cases. People aged 0-4 were proved to be significantly susceptible to PM10 and NO2; 5-14 ages were significantly susceptible to PM2.5 and PM10; and 15-24 ages were significantly susceptible to all the analyzed air pollutants. Air pollution effects tended to be null or negative for patients aged over 25, which might be due to the small number of influenza-like cases in this age group. This study can be useful for understanding the adverse health effects of air pollution and the cause of influenza-like illness. PMID:26766354

    Joshi, Roshni; Venkatesan, Sudhir; Myles, Puja R

    2016-01-01

    Background. Cholesterol lowering drugs HMG-CoA reductase inhibitors (statins) and PPARα activators (fibrates) have been shown to reduce host inflammation via non-disease specific immunomodulatory mechanisms. Recent studies suggest that commonly prescribed drugs in general practice, statins and fibrates, may be beneficial in influenza-like illness related mortality. This retrospective cohort study examines the association between two lipid lowering drugs, statins and fibrates, and all-cause 30-day mortality following a medically attended acute respiratory illness (MAARI). Methods. Primary care patient data were retrospectively extracted from the UK Clinical Practice Research Datalink (CPRD) database. The sample comprised 201,179 adults aged 30 years or older experiencing a MAARI episode. Patient exposure to statins or fibrates was coded as separate dichotomous variables and deemed current if the most recent GP prescription was issued in the 30 days prior to MAARI diagnosis. Multivariable logistic regression and Cox regression were used for analyses. Adjustment was carried out for chronic lung disease, heart failure, metformin and glitazones, comorbidity burden, socio-demographic and lifestyle variables such as smoking status and body mass index (BMI). Statistical interaction tests were carried out to check for effect modification by gender, body mass index, smoking status and comorbidity. Results. A total of 1,096 (5%) patients died within the 30-day follow up period. Of this group, 213 (19.4%) were statin users and 4 (0.4%) were fibrate users. After adjustment, a significant 35% reduction in odds [adj OR; 0.65 (95% CI [0.52-0.80])] and a 33% reduction in the hazard [adj HR: 0.67 (95% CI [0.55-0.83])] of all-cause 30-day mortality following MAARI was observed in statin users. A significant effect modification by comorbidity burden was observed for the association between statin use and MAARI-related mortality. Fibrate use was associated with a non

    2016-06-01

    Renal replacement treatment (RRT) is required in severe acute kidney injury, and a functioning central venous catheter (CVC) is crucial. Twenty-eight children younger than 16 years have been treated at the University Medical Centre Ljubljana between 2003 and 2012 with either acute hemodialysis (HD) and/or plasma exchange (PE), and were included in our study. The age of the patients ranged from 2 days to 14.1 years. Sixty-six CVCs were inserted (52% de novo, 48% guide wire). The sites of insertion were the jugular vein in 20% and the femoral vein in 80%. Catheters were in function from 1 day to 27 days. The most common cause for CVC removal or exchange was catheter dysfunction (50%). CVCs were mostly inserted in the femoral vein, which is the preferred site of insertion in acute HD/PE because of the smaller number of complications. PMID:27312920

  18. Acute gastrointestinal, genitourinary, and dermatological toxicity during dose-escalated 3D-conformal radiation therapy (3DCRT) using an intrarectal balloon for prostate gland localization and immobilization

    Purpose: We determined the acute gastrointestinal (GI), genitourinary (GU), and dermatologic (D) toxicity during dose-escalated three-dimensional conformal radiation therapy (3DCRT). A modified intrarectal balloon (Medrad) was used for prostate gland localization and immobilization. Methods: Forty-six men with clinical category T1c to T3a, and at least one high-risk feature (PSA >10, Gleason ≥7, or MRI evidence of extracapsular extension or seminal vesical invasion) comprised the study cohort. Treatment consisted of hormonal therapy and 4-field 3DCRT using an intrarectal balloon for the initial 15 of 40 treatments. Planning treatment volume dose was 72 Gy (95% normalization). A Mantel-Haenzel Chi-square test compared the distribution of GU, GI, and D symptoms at baseline and at end of treatment (EOT). Results: There was no significant difference between the 2 time points in the proportion of patients with bowel symptoms (p = 0.73), tenesmus (p = 0.27), nocturia (p = 1.00), or GU urgency (p = 0.40). However, there was a significant decrease in GU frequency (70% vs. 50%, p = 0.46) as a result of medical interventions and a significant increase in hemorrhoidal irritation (4% vs. 20%, p = 0.02) and anal cutaneous skin reaction (0% vs. 70%, p < 0.001). By 3 months after EOT compared to baseline, there was no significant difference in the proportion of patients experiencing hemorrhoidal bleeding (4% vs. 8%, p = 0.52), requiring intervention for hemorrhoidal symptoms (7% vs. 5%, p = 0.8), or experiencing persistent anal cutaneous skin reaction (0% vs. 3%, p = 0.31). Conclusion: Dose-escalated 3DCRT using an intrarectal balloon for prostate localization and immobilization was well tolerated. Acute GU, GI, and D symptoms resolved with standard dietary or medical interventions by the EOT or shortly thereafter

    2014-01-01

    Background The intake of meat, particularly processed meat, is a dietary risk factor for diabetes. Meat intake impairs insulin sensitivity and leads to increased oxidative stress. However, its effect on postprandial gastrointestinal hormone (GIH) secretion is unclear. We aimed to investigate the acute effects of two standardized isocaloric meals: a processed hamburger meat meal rich in protein and saturated fat (M-meal) and a vegan meal rich in carbohydrates (V-meal). We hypothesized that the...

    Full Text Available Abstract Background Expatriates are a distinct population at unique risk for health problems related to their travel exposure. Methods We analyzed GeoSentinel data comparing ill returned expatriates with other travelers for demographics, travel characteristics, and proportionate morbidity (PM for travel-related illness. Results Our study included 2,883 expatriates and 11,910 non-expatriates who visited GeoSentinel clinics ill after travel. Expatriates were more likely to be male, do volunteer work, be long-stay travelers (>6 months, and have sought pre-travel advice. Compared to non-expatriates, expatriates returning from Africa had higher proportionate morbidity (PM for malaria, filariasis, schistosomiasis, and hepatitis E; expatriates from the Asia-Pacific region had higher PM for strongyloidiasis, depression, and anxiety; expatriates returning from Latin America had higher PM for mononucleosis and ingestion-related infections (giardiasis, brucellosis. Expatriates returning from all three regions had higher PM for latent TB, amebiasis, and gastrointestinal infections (other than acute diarrhea compared to non-expatriates. When the data were stratified by travel reason, business expatriates had higher PM for febrile systemic illness (malaria and dengue and vaccine-preventable infections (hepatitis A, and volunteer expatriates had higher PM for parasitic infections. Expatriates overall had higher adjusted odds ratios for latent TB and lower odds ratios for acute diarrhea and dermatologic illness. Conclusions Ill returned expatriates differ from other travelers in travel characteristics and proportionate morbidity for specific diseases, based on the region of exposure and travel reason. They are more likely to present with more serious illness.

    Full Text Available Abstract Background Minimization of hemodynamic instability during renal replacement therapy (RRT in patients with acute kidney injury (AKI is often challenging. We examined the relative hemodynamic tolerability of sustained low efficiency dialysis (SLED and continuous renal replacement therapy (CRRT in critically ill patients with AKI. We also compared the feasibility of SLED administration with that of CRRT and intermittent hemodialysis (IHD. Methods This cohort study encompassed four critical care units within a single university-affiliated medical centre. 77 consecutive critically ill patients with AKI who were treated with CRRT (n = 30, SLED (n = 13 or IHD (n = 34 and completed at least two RRT sessions were included in the study. Overall, 223 RRT sessions were analyzed. Hemodynamic instability during a given session was defined as the composite of a > 20% reduction in mean arterial pressure or any escalation in pressor requirements. Treatment feasibility was evaluated based on the fraction of the prescribed therapy time that was delivered. An interrupted session was designated if Results Hemodynamic instability occurred during 22 (56.4% SLED and 43 (50.0% CRRT sessions (p = 0.51. In a multivariable analysis that accounted for clustering of multiple sessions within the same patient, the odds ratio for hemodynamic instability with SLED was 1.20 (95% CI 0.58-2.47, as compared to CRRT. Session interruption occurred in 16 (16.3, 30 (34.9 and 11 (28.2 of IHD, CRRT and SLED therapies, respectively. Conclusions In critically ill patients with AKI, the administration of SLED is feasible and provides comparable hemodynamic control to CRRT.

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

  5. Acute-onset severe gastrointestinal tract hemorrhage in a postoperative patient taking rivaroxaban after total hip arthroplasty: a case report

    Boland Michael

    2012-05-01

    Full Text Available Abstract Introduction Rivaroxaban, a new oral anticoagulant, is currently licensed for use in patients undergoing orthopedic surgery. It is more efficacious than other anticoagulants such as low molecular weight heparin and does not require daily monitoring. It has also been shown to be efficacious in patients with venous thromboembolism and acute coronary syndrome. Although hemorrhage is a known side effect of this new anticoagulant, we could find no case reports in the literature of patients suffering severe hemorrhage whilst taking rivaroxaban. Thus, we describe the first case of potentially fatal hemorrhage in a patient taking rivaroxaban. Case presentation We report the case of a 58-year-old Caucasian man with acute-onset severe per rectal bleeding who had undergone total hip arthroplasty four weeks prior to the onset of symptoms and was taking rivaroxaban in the postoperative period. Rivaroxaban was discontinued immediately but, having required nine units of packed red blood cells in a peripheral hospital due to a rapidly decreasing hemoglobin level, our patient was transferred to our tertiary referral center where he required a further eight units of packed red blood cells over a 48-hour period to manage his ongoing hemorrhage and maintain hemodynamic stability. No source of bleeding was found on computed tomography angiography and our patient’s condition improved over the following 48 hours with cessation of the hemorrhage. Our patient was discharged home well several days later. A follow-up colonoscopy one week after his discharge was normal. Conclusion Although advantageous with regard to its oral availability and ongoing use without the need for daily monitoring, rivaroxaban does not come without rare but severe side effects. When severe per rectal bleeding occurs in a patient taking rivaroxaban, discontinuation of the offending agent and aggressive hematological replacement are the mainstays of treatment, especially when no

    Endothelial dysfunction contributes to the development of acute kidney injury (AKI) in animal models of ischemia reperfusion injury and sepsis. There are limited data on markers of endothelial dysfunction in human AKI. We hypothesized that Protein C (PC) and soluble thrombomodulin (sTM) levels could predict AKI. We conducted a multicenter prospective study in 80 patients to assess the relationship of PC and sTM levels to AKI, defined by the AKIN creatinine (AKI Scr) and urine output criteria ...

    2012-01-01

    Introduction The Risk, Injury, Failure, Loss, and End-Stage Renal Disease (RIFLE) is a consensus-based classification system for diagnosing acute kidney insufficiency (AKI), based on serum creatinine (SCr) and urine output criteria (RIFLESCr+UO). The urine output criteria, however, are frequently discarded and many studies in the literature applied only the SCr criteria (RIFLESCr). We diagnosed AKI using both RIFLE methods and compared the effects on time to AKI diagnosis, AKI incidence and A...

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

    Norman Oneil Machado

    2011-03-01

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

    The data show respiratory variables in 108 critically ill patients with acute respiratory failure placed on proportional assist ventilation with load adjustable gain factors (PAV+) after at least 36 h on passive mechanical ventilation. PAV+ was continued for 48 h until the patients met pre-defined criteria either for switching to controlled modes or for breathing without ventilator assistance. Data during passive mechanical ventilation and during PAV+ are reported. Data are acquired from the whole population, as well as from patients with and without acute respiratory distress syndrome. The reported variables are tidal volume, driving pressure (ΔP, the difference between static end-inspiratory plateau pressure and positive end-expiratory airway pressure), respiratory system compliance and resistance, and arterial blood gasses. The data are supplemental to our original research article, which described individual ΔP in these patients and examined how it related to ΔP when the same patients were ventilated with passive mechanical ventilation using the currently accepted lung-protective strategy "Driving pressure during assisted mechanical ventilation. Is it controlled by patient brain?" [1]. PMID:27358909

    2016-02-01

    The Food and Drug Administration and the European Medicines Agency sent a warning in 2010 discouraging the concomitant use of clopidogrel with omeprazole or esomeprazole. The purpose is to know the gastroprotective approach in patients with acute coronary syndrome (ACS) and the level of follow-up of the alert. In 17 hospitals with catheterization laboratory in Spain, 1 per region, we studied 25 consecutive patients per hospital whose diagnosis of discharge since October 1, 2013, had been any type of ACS. We analyzed their baseline clinical profile, the gatroprotective agents at admission and discharge and the antiplatelet therapy at discharge. The number of patients included was 425: age 67.2 ± 12.5 years, women 29.8%, diabetes 36.5%. The patients presented unstable angina in 21.6%, non-ST-elevation myocardial infarction in 35.3% and ST-elevation myocardial infarction in 43.1%. Conservative approach was chosen in 17.9%, bare-metal stents 32.2%, ≥ 1 drug-eluting stent 48.5%, and surgery 1.4%. Aspirin was indicated in 1.9%, aspirin + clopidogrel 73.6%, aspirin + prasugrel 17.6%, and aspririn + ticagrelor 6.8%. Gastroprotective agents were present in 40.2% patients at admission and this percentage increased to 93.7% at discharge. Of the 313 (73.6%) on clopidogrel in 96 (30.6%) was combined with omeprazole and 3 (0.95%) with esomeprazole, whereas the most commonly used was pantoprazole with 190 patients (44.7%). In conclusion, almost the totality of the patients with an ACS receive gastroprotective agents at the moment of discharge, most of them with proton-pump inhibitors. In one every 3 cases of the patients who are on clopidogrel, the recommendation of the Food and Drug Administration and the European Medicines Agency is not followed. PMID:26708640

  14. [Gastrointestinal bleeding].

    Lanas, Ángel

    2015-09-01

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

    2016-01-01

    Background and Aims: This study aims to evaluate the sleep quality, architecture, sleep-related quality of life, and sleep-disordered breathing (SDB) in acute respiratory distress syndrome (ARDS) survivors early after discharge. Materials and Methods: In this prospective, observational study, consecutive patients with ARDS discharged from the Intensive Care Unit (ICU) underwent evaluation with Epworth sleepiness scale (ESS), Pittsburgh Sleep Quality Index (PSQI), Functional Outcomes of Sleep Questionnaire (FOSQ), and overnight polysomnography. Patients having one or more of the following characteristics were classified as having abnormal sleep: ESS>10, PSQI>5, FOSQ 10, seven (35%) had global PSQI>5 and one had FOSQ <17.9. Ten (50%) patients had at least one characteristic that suggested abnormal sleep (4 insomnia, 2 central sleep apnea, 1 obstructive sleep apnea, 1 REM-SDB, and 2 with a high PSQI, but no specific sleep abnormality). Conclusions: Sleep disturbances are common in ARDS survivors early after discharge from the ICU. PMID:27390455

  16. Mortality, severe acute respiratory infection, and influenza-like illness associated with influenza A(H1N1pdm09 in Argentina, 2009.

    Eduardo Azziz-Baumgartner

    Full Text Available INTRODUCTION: While there is much information about the burden of influenza A(H1N1pdm09 in North America, little data exist on its burden in South America. METHODS: During April to December 2009, we actively searched for persons with severe acute respiratory infection and influenza-like illness (ILI in three sentinel cities. A proportion of case-patients provided swabs for influenza testing. We estimated the number of case-patients that would have tested positive for influenza by multiplying the number of untested case-patients by the proportion who tested positive. We estimated rates by dividing the estimated number of case-patients by the census population after adjusting for the proportion of case-patients with missing illness onset information and ILI case-patients who visited physicians multiple times for one illness event. RESULTS: We estimated that the influenza A(H1N1pdm09 mortality rate per 100,000 person-years (py ranged from 1.5 among persons aged 5-44 years to 5.6 among persons aged ≥ 65 years. A(H1N1pdm09 hospitalization rates per 100,000 py ranged between 26.9 among children aged <5 years to 41.8 among persons aged ≥ 65 years. Influenza A(H1N1pdm09 ILI rates per 100 py ranged between 1.6 among children aged <5 to 17.1 among persons aged 45-64 years. While 9 (53% of 17 influenza A(H1N1pdm09 decedents with available data had obesity and 7 (17% of 40 had diabetes, less than 4% of surviving influenza A(H1N1pdm09 case-patients had these pre-existing conditions (p ≤ 0.001. CONCLUSION: Influenza A(H1N1pdm09 caused a similar burden of disease in Argentina as in other countries. Such disease burden suggests the potential value of timely influenza vaccinations.

  17. Gastrointestinal stromal tumours: pictorial review

    Gastrointestinal stromal tumours (GIST) are the most common mesenchymal tumours of the alimentary tract. They normally involve the stomach, the small bowel, or the colon. Localisation within the oesophagus, rectum, mesentery, omentum, or retroperitoneum is less common, GISTs are immunohistochemically identified by the expression of the c-kit protein, which is not detected in other mesenchymal tumours. The role of imaging includes the detection (subjects with occult gastro-intestinal bleeding, incidental recognition, etc.), characterisation, analysis of relations between mass and gastrointestinal wall, staging, prognostic assessment (recognition of signs of malignancy and unfavourable prognosis), and follow-up during specific treatment. Owing to the frequent exophytic growth of these lesions, differentiation of these tumours from non digestive lesions of different nature is a common diagnostic problem. Imaging findings usually allow differentiation from gastrointestinal epithelial tumours but not from non-epithelial tumours, for which histological confirmation is necessary, in part to verify potential response to therapy. Smaller lesions, which are usually benign, tend to be well-defined, relatively homogeneous, and with intraluminal growth. Larger lesions normally show well-defined or ill defined margins, inhomogeneous density both on unenhanced and on contrast-enhanced scans, with combined intraluminal/extra luminal growth and a tendency to spread to surrounding structures. Internal attenuation is often necrotic or clearly fluid. Signs of high-grade GIST include liver metastasis, gastrointestinal wall infiltration, large volume, irregular surface, ill-defined margins, inhomogeneous enhancement and peritoneal spread. Recurrences usually share the appearance of the larger, primary malignant GIST

  18. Impact of post operative intensity modulated radiotherapy on acute gastro-intestinal toxicity for patients with endometrial cancer: Results of the phase II RTCMIENDOMETRE French multicentre trial

    Purpose/objective: Whole “conventional” pelvic irradiation (up to 45–50 Gy) following hysterectomy is associated with a high rate of adverse gastro-intestinal (GI) adverse events, of which around 60% correspond to acute grade 2 toxicity. The phase II RTCMIENDOMETRE trial was designed to test the hypothesis that IMRT could reduce the incidence of grade 2 or more acute GI toxicity to less than 30% in patients irradiated post-operatively for an endometrial cancer. Materials/methods: Patients with post-operative stage Ib G3, Ic or II endometrial carcinomas with no history of chronic inflammatory bowel disease were eligible. Guidelines for volume delineation and dose prescription were detailed in the protocol. The investigators were advised to use a web-based atlas developed for the RTOG 0418 study. The dose of the vaginal and nodal PTV was 45 Gy in 25 fractions. To assess the ability of the participating centres to comply with the protocol guidelines, they were requested to complete a dummy run procedure before inclusion of their 1st patient. GI and genito-urinary (GU) toxicity were graded according to the CTCAE V 3.0 classification and were prospectively recorded every week during irradiation, as well as at time of brachytherapy insertions and during the follow-up visit at week 15 (W15). Special attention was given to note any changes to the grade of adverse events between W5 and W15. Results: From May 2008 to April 2010, 49 patients from 6 centres were recruited for the trial. One patient could not be treated, one patient died of vascular stroke at W3 without toxicity, and 1 patient refused to be followed-up after treatment. Thus, 46 cases were available for analysis at W15. The distribution by stage was as follows: Ib 16.3%, Ic 64.2%, II 20.4%. Thirty six patients (75%) received an additional vaginal vault boost of 6–10 Gy delivered by HDR brachytherapy in 1 or 2 fractions. Among the 47 patients who completed IMRT, 27% (95% CI 14.5–39.7%) developed at

  19. STOPP (Screening Tool of Older Persons' potentially inappropriate Prescriptions): application to acutely ill elderly patients and comparison with Beers' criteria.

    Gallagher, Paul

    2012-02-03

    Introduction: STOPP (Screening Tool of Older Persons\\' potentially inappropriate Prescriptions) is a new, systems-defined medicine review tool. We compared the performance of STOPP to that of established Beers\\' criteria in detecting potentially inappropriate medicines (PIMs) and related adverse drug events (ADEs) in older patients presenting for hospital admission. METHODS: we prospectively studied 715 consecutive acute admissions to a university teaching hospital. Diagnoses, reason for admission and concurrent medications were recorded. STOPP and Beers\\' criteria were applied. PIMs with clear causal connection or contribution to the principal reason for admission were determined. RESULTS: median patient age (interquartile range) was 77 (72-82) years. Median number of prescription medicines was 6 (range 0-21). STOPP identified 336 PIMs affecting 247 patients (35%), of whom one-third (n = 82) presented with an associated ADE. Beers\\' criteria identified 226 PIMs affecting 177 patients (25%), of whom 43 presented with an associated ADE. STOPP-related PIMs contributed to 11.5% of all admissions. Beers\\' criteria-related PIMs contributed to significantly fewer admissions (6%). CONCLUSION: STOPP criteria identified a significantly higher proportion of patients requiring hospitalisation as a result of PIM-related adverse events than Beers\\' criteria. This finding has significant implications for hospital geriatric practice.

  20. Effects of a dietary intervention on acute gastrointestinal side effects and other aspects of health-related quality of life: A randomized controlled trial in prostate cancer patients undergoing radiotherapy

    Purpose: To study the effect of a dietary intervention on acute gastrointestinal side effects and other aspects of health-related quality of life (HRQOL) in prostate cancer patients referred to radiotherapy. Materials and methods: A total of 130 patients were randomly assigned to one of two groups: an intervention group (IG, n = 64), instructed to reduce their intake of insoluble dietary fibres and lactose, a standard care group (SC, n = 66), instructed to continue their normal diet. Gastrointestinal side effects and other aspects of HRQOL were evaluated from baseline up to 2 months after completed radiotherapy, using the EORTC QLQ-C30 and QLQ-PR25 and the study-specific Gastrointestinal Side Effects Questionnaire (GISEQ). A scale indicating adherence to dietary instructions was developed from a Food Frequency Questionnaire (FFQ), with lower scores representing better compliance. Descriptive and inferential statistical analyses were conducted. Results: There was an interaction effect between randomization and time in the FFQ Scores (p < 0.001), indicating that both groups followed their assigned dietary instructions. The dietary intervention had no effect on gastrointestinal side effects or other aspects of HRQOL. During radiotherapy, the percentage of patients with bowel symptoms and bloated abdomen was lower in IG compared to SC, but the between-group differences were not statistically significant. During radiotherapy, the percentage of patients with bowel symptoms, urinary symptoms, pain, fatigue and diminished physical and role functioning increased in both groups. Conclusions: The dietary intervention had no effect on gastrointestinal side effects or other aspects of HRQOL. The tendency towards lower prevalence of bowel symptoms in IG may indicate some positive effect of the dietary intervention, but methodological refinements, clearer results and longer follow-up are needed before the value of diet change can be established with certainty.

  1. Gastrointestinal lymphomas

    Malignant lymphomas of the gastrointestinal tract have been the subject of numerous recent studies aimed at defining the radiological appearances of these rare entities, and in particular the non-Hodgkin's lymphomas (NHL). Owing to the submucosal origin of the disease, even deep biopsies performed with state-of-the-art techniques are not always positive. This explains the continued importance of barium studies, especially since therapeutic approaches have evolved. As an example, surgery is no longer the treatment of choice for disease sites in the stomach, the most frequent site of gastrointestinal lymphoma, as many authors now advocate radiotherapy and above all now chemotherapy. Furthermore, computed tomography (CT) and ultrasonography now allow improved evaluation of subdiaphragmatic nodes and the extent of disease within the gastrointestinal tract. The radiological features of gastrointestinal NHL and Hodgkin's disease (HD) warrant differentiation because of the differences in their patterns of anatomical distribution and frequency. Nearly one in every 20 cases of NHL is a primary gastrointestinal site with a favorable prognosis. In contrast to carcinomas, NHL generally does not induce any fibrolastic stroma reaction. The resultant large lesions are readily demonstrated radiologically, and despite the frequent absence of clinical signs, their size suggests the correct diagnosis. Both primary and secondary HD are rare, and in contrast to NHL their prognosis is poor, as they correspond to stage IV disease from the outset. HD is associated with an intense fibrolastic stroma reaction causing moderate-sized focal lesions suggestive of carcinoma

  2. Levels of protein C and soluble thrombomodulin in critically ill patients with acute kidney injury: a multicenter prospective observational study.

    Josée Bouchard

    Full Text Available Endothelial dysfunction contributes to the development of acute kidney injury (AKI in animal models of ischemia reperfusion injury and sepsis. There are limited data on markers of endothelial dysfunction in human AKI. We hypothesized that Protein C (PC and soluble thrombomodulin (sTM levels could predict AKI. We conducted a multicenter prospective study in 80 patients to assess the relationship of PC and sTM levels to AKI, defined by the AKIN creatinine (AKI Scr and urine output criteria (AKI UO. We measured marker levels for up to 10 days from intensive care unit admission. We used area under the curve (AUC and time-dependent multivariable Cox proportional hazard model to predict AKI and logistic regression to predict mortality/non-renal recovery. Protein C and sTM were not different in patients with AKI UO only versus no AKI. On intensive care unit admission, as PC levels are usually lower with AKI Scr, the AUC to predict the absence of AKI was 0.63 (95%CI 0.44-0.78. The AUC using log10 sTM levels to predict AKI was 0.77 (95%CI 0.62-0.89, which predicted AKI Scr better than serum and urine neutrophil gelatinase-associated lipocalin (NGAL and cystatin C, urine kidney injury molecule-1 and liver-fatty acid-binding protein. In multivariable models, PC and urine NGAL levels independently predicted AKI (p=0.04 and 0.02 and PC levels independently predicted mortality/non-renal recovery (p=0.04. In our study, PC and sTM levels can predict AKI Scr but are not modified during AKI UO alone. PC levels could independently predict mortality/non-renal recovery. Additional larger studies are needed to define the relationship between markers of endothelial dysfunction and AKI.

    -dwelling subjects. The total number of inappropriate prescriptions identified using the Beers\\' criteria (ID) was 148 affecting 121 patients. The Beers\\' criteria (CD) identified 69 inappropriate prescriptions in 60 patients and the IPET identified 112 inappropriate prescriptions in 78 patients. The Beers criteria (ID and CD combined) identified at least one inappropriate prescription in 34% of subjects and the IPET identified one in at least 22% of subjects. CONCLUSIONS: This study identifies high rates of use of inappropriate medications in community-dwelling elderly presenting with acute illness to hospital. These are comparable with inappropriate prescribing rates identified in previous studies. The revised Beers\\' criteria (2003) identified more inappropriate prescriptions than the IPET in this population of elders.

  5. Efficacy of a high-dose in addition to daily low-dose vitamin A in children suffering from severe acute malnutrition with other illnesses.

    Samima Sattar

    Full Text Available BACKGROUND: Efficacy of high-dose vitamin A (VA in children suffering from severe acute malnutrition (SAM has recently been questioned. This study compared the efficacy of a single high-dose (200,000 IU in addition to daily low-dose (5000 IU VA in the management of children suffering from SAM with diarrhea and/or acute lower respiratory tract infection (ALRI. METHODS: In a randomized, double-blind, controlled clinical trial in icddr,b, Bangladesh during 2005-07, children aged 6-59 months with weight-for-height <-3 Z-score and/or bipedal edema (SAM received either a high-dose VA or placebo on admission day. Both the groups received 5,000 IU/day VA in a multivitamins drop for 15 days and other standard treatment which is similar to WHO guidelines. RESULTS: A total 260 children (130 in each group were enrolled. All had diarrhea, 54% had concomitant ALRI, 50% had edema, 48.5% were girl with a mean±SD age of 16±10 months. None had clinical signs of VA deficiency. Mean±SD baseline serum retinol was 13.15±9.28 µg/dl, retinol binding protein was 1.27±0.95 mg/dl, and pre-albumin was 7.97±3.96 mg/dl. Median (inter quartile range of C-reactive protein was 7.8 (2.1, 22.2 mg/L. Children of the two groups did not differ in any baseline characteristic. Over the 15 days treatment period resolution of diarrhea, ALRI, edema, anthropometric changes, and biochemical indicators of VA were similar between the groups. The high-dose VA supplementation in children with SAM did not show any adverse event. CONCLUSIONS: Efficacy of daily low-dose VA compared to an additional single high-dose was not observed to be better in the management of children suffering from SAM with other acute illnesses. A single high-dose VA may be given especially where the children with SAM may leave the hospital/treatment center early. TRIAL REGISTRATION: ClinicalTrials.gov NCT00388921.

  8. The plasma level and biomarker value of neutrophil gelatinase-associated lipocalin in critically ill patients with acute kidney injury are not affected by continuous venovenous hemofiltration and anticoagulation applied

    Schilder, Louise; Nurmohamed, S Azam; ter Wee, Pieter M.; Paauw, Nanne J.; Girbes, Armand RJ; Beishuizen, Albertus; Beelen, Robert HJ; Groeneveld, AB Johan

    2014-01-01

    Introduction Neutrophil gelatinase-associated lipocalin (NGAL) is a biomarker of acute kidney injury (AKI), and levels reflect severity of disease in critically ill patients. However, continuous venovenous hemofiltration (CVVH) may affect plasma levels by clearance or release of NGAL by activated neutrophils in the filter, dependent on the anticoagulation regimen applied. We therefore studied handling of NGAL by CVVH in patients with AKI. Methods Immediately before initiation of CVVH, prefilt...

    Full Text Available There are few published studies describing severe acute respiratory illness (SARI epidemiology amongst older children and adults from high HIV-prevalence settings. We aimed to describe SARI epidemiology amongst individuals aged ≥5 years in South Africa.We conducted prospective surveillance for individuals with SARI from 2009-2012. Using polymerase chain reaction, respiratory samples were tested for ten viruses, and blood for pneumococcal DNA. Cumulative annual SARI incidence was estimated at one site with population denominators.We enrolled 7193 individuals, 9% (621/7067 tested positive for influenza and 9% (600/6519 for pneumococcus. HIV-prevalence was 74% (4663/6334. Among HIV-infected individuals with available data, 41% of 2629 were receiving antiretroviral therapy (ART. The annual SARI hospitalisation incidence ranged from 325-617/100,000 population. HIV-infected individuals experienced a 13-19 times greater SARI incidence than HIV-uninfected individuals (p7 days rather than <2 days (OR1.7; 95%CI:1.2-2.2 and had a higher case-fatality ratio (8% vs 5%;OR1.7; 95%CI:1.2-2.3, but were less likely to be infected with influenza (OR 0.6; 95%CI:0.5-0.8.

    Acute febrile illness (AFI) is associated with substantial morbidity and mortality worldwide, yet an etiologic agent is often not identified. Convalescent-phase serology is impractical, blood culture is slow, and many pathogens are fastidious or impossible to cultivate. We developed a real-time PCR-based TaqMan array card (TAC) that can test six to eight samples within 2.5 h from sample to results and can simultaneously detect 26 AFI-associated organisms, including 15 viruses (chikungunya, Crimean-Congo hemorrhagic fever [CCHF] virus, dengue, Ebola virus, Bundibugyo virus, Sudan virus, hantaviruses [Hantaan and Seoul], hepatitis E, Marburg, Nipah virus, o'nyong-nyong virus, Rift Valley fever virus, West Nile virus, and yellow fever virus), 8 bacteria (Bartonella spp., Brucella spp., Coxiella burnetii, Leptospira spp., Rickettsia spp., Salmonella enterica and Salmonella enterica serovar Typhi, and Yersinia pestis), and 3 protozoa (Leishmania spp., Plasmodium spp., and Trypanosoma brucei). Two extrinsic controls (phocine herpesvirus 1 and bacteriophage MS2) were included to ensure extraction and amplification efficiency. Analytical validation was performed on spiked specimens for linearity, intra-assay precision, interassay precision, limit of detection, and specificity. The performance of the card on clinical specimens was evaluated with 1,050 blood samples by comparison to the individual real-time PCR assays, and the TAC exhibited an overall 88% (278/315; 95% confidence interval [CI], 84% to 92%) sensitivity and a 99% (5,261/5,326, 98% to 99%) specificity. This TaqMan array card can be used in field settings as a rapid screen for outbreak investigation or for the surveillance of pathogens, including Ebola virus. PMID:26491176

  12. Etiology and Incidence of viral and bacterial acute respiratory illness among older children and adults in rural western Kenya, 2007-2010.

    Daniel R Feikin

    Full Text Available BACKGROUND: Few comprehensive data exist on disease incidence for specific etiologies of acute respiratory illness (ARI in older children and adults in Africa. METHODOLOGY/PRINCIPAL FINDINGS: From March 1, 2007, to February 28, 2010, among a surveillance population of 21,420 persons >5 years old in rural western Kenya, we collected blood for culture and malaria smears, nasopharyngeal and oropharyngeal swabs for quantitative real-time PCR for ten viruses and three atypical bacteria, and urine for pneumococcal antigen testing on outpatients and inpatients meeting a ARI case definition (cough or difficulty breathing or chest pain and temperature >38.0 °C or oxygen saturation 5 years old (adjusted annual incidence 12.0 per 100 person-years, influenza A virus was the most common virus (22% overall; 11% inpatients, 27% outpatients and Streptococcus pneumoniae was the most common bacteria (16% overall; 23% inpatients, 14% outpatients, yielding annual incidences of 2.6 and 1.7 episodes per 100 person-years, respectively. Influenza A virus, influenza B virus, respiratory syncytial virus (RSV and human metapneumovirus were more prevalent in swabs among cases (22%, 6%, 8% and 5%, respectively than controls. Adenovirus, parainfluenza viruses, rhinovirus/enterovirus, parechovirus, and Mycoplasma pneumoniae were not more prevalent among cases than controls. Pneumococcus and non-typhi Salmonella were more prevalent among HIV-infected adults, but prevalence of viruses was similar among HIV-infected and HIV-negative individuals. ARI incidence was highest during peak malaria season. CONCLUSIONS/SIGNIFICANCE: Vaccination against influenza and pneumococcus (by potential herd immunity from childhood vaccination or of HIV-infected adults might prevent much of the substantial ARI incidence among persons >5 years old in similar rural African settings.

    Full Text Available Abstract Background Early enteral nutrition is recommended in cases of critical illness. It is unclear whether this recommendation is of most benefit to extremely ill patients. We aim to determine the association between illness severity and commencement of enteral feeding. Methods One hundred and eight critically ill patients were grouped as “less severe” and “more severe” for this cross-sectional, retrospective observational study. The cut off value was based on Acute Physiology and Chronic Health Evaluation II score 20. Patients who received enteral feeding within 48 h of medical intensive care unit (ICU admission were considered early feeding cases otherwise they were assessed as late feeding cases. Feeding complications (gastric retention/vomiting/diarrhea/gastrointestinal bleeding, length of ICU stay, length of hospital stay, ventilator-associated pneumonia, hospital mortality, nutritional intake, serum albumin, serum prealbumin, nitrogen balance (NB, and 24-h urinary urea nitrogen data were collected over 21 days. Results There were no differences in measured outcomes between early and late feedings for less severely ill patients. Among more severely ill patients, however, the early feeding group showed improved serum albumin (p = 0.036 and prealbumin (p = 0.014 but worsened NB (p = 0.01, more feeding complications (p = 0.005, and prolonged ICU stays (p = 0.005 compared to their late feeding counterparts. Conclusions There is a significant association between severity of illness and timing of enteral feeding initiation. In more severe illness, early feeding was associated with improved nutritional outcomes, while late feeding was associated with reduced feeding complications and length of ICU stay. However, the feeding complications of more severely ill early feeders can be handled without significantly affecting nutritional intake and there is no eventual difference in length of hospital stay or mortality

    Background The optimal timing to start continuous renal replacement therapy (CRRT) for acute kidney injury (AKI) patients has not been accurately established. The recently proposed risk, injury, failure, loss, end-stage kidney disease (RIFLE) criteria for diagnosis and classification of AKI may provide a method for clinicians to decide the "optimal timing" for starting CRRT under uniform guidelines. The present study aimed: (1) to analyze the correlation between RIFLE stage at the start of CRRT and 90-day survival rate after CRRT start, (2) to further investigate the correlation of RIFLE stage with the malignant kidney outcome in the 90-day survivors, and (3) to determine the influence of the timing of CRRT defined by RIFLE classification on the 90-day survival and malignant kidney outcome in 90-day survivors. Methods A retrospective cohort analysis was performed on the data of 106 critically ill patients with AKI, treated with CRRT during a 6-year period in a university affiliated surgical intensive care unit (SICU). Information such as sex, age, RIFLE stage, sepsis, sepsis-related organ failure assessment (SOFA) score, number of organ failures before CRRT, CRRT time during SiCU, survival, and kidney outcome conditions at 90 days after CRRT start was collected. According to their baseline severity of AKI at the start of CRRT, the patients were assigned to three groups according to the increasing severity of RIFLE stages: RIFLE-R (risk of renal dysfunction, R), RIFLE-I (injury to the kidney, I) and RIFLE-F (failure of kidney function, F) using RIFLE criteria. The malignant kidney outcome was classified as RIFLE-L (loss of kidney function, L) or RIFLE-E (end-stage kidney disease, E) using RIFLE criteria. The correlation between RIFLE stage and 90-day survival rate was analyzed among these three RIFLE-categorized groups. Additionally, the association between RIFLE stage and the malignant kidney outcome (RIFLE-L+RIFLF-E) in the 90-day survivors was analyzed

    Retrospective evaluation of interventional embolization therapy in the treatment of gastrointestinal hemorrhage over a long-term observation period from 1989 to 1997. Included in the study were 35 patients (age range 18-89 years) with gastrointestinal bleeding (GI) referred for radiological intervention either primarily or following unsuccessful endoscopy or surgery. Sources of GI bleeding included gastric and duodenal ulcers (n = 7), diverticula (n = 3), erosion of the intestinal wall secondary to malignancy (n = 6), vascular malformations (n = 4), and hemorrhoids (n = 2), as well as from postoperative (n = 6), posttraumatic (n = 2), postinflammatory (n = 4) or unknown (n = 1) causes. Ethibloc (12 cases) or metal coils (14 cases) were predominantly used as embolisates. In addition, combinations of tissue adhesive and gelfoam particles and of coils and Ethibloc were used (six cases). Finally, polyvinyl alcohol particles, a coated stent, and an arterial wire dissection were utilized in one case each. Bleeding was stopped completely in 29 of 35 cases (83 %). In one case (3 %) the source of bleeding was recognized but the corresponding vessel could not be catheterized. In five other cases (14 %) there was partial success with reduced, though still persistent, bleeding. The rate of complications was 14 %, including four instances of intestinal ischemia with fatal outcome in the first years, and, later, one partial infarction of the spleen without serious consequences. Gastrointestinal hemorrhage can be controlled in a high percentage of patients, including the seriously ill and those who had previously undergone surgery, with the use of minimally invasive interventional techniques. The availability of minicoils instead of fluid embolization agents has reduced the risk of serious complications. (orig.)

  20. Estimation of the national disease burden of influenza-associated severe acute respiratory illness in Kenya and Guatemala: a novel methodology.

    James A Fuller

    Full Text Available BACKGROUND: Knowing the national disease burden of severe influenza in low-income countries can inform policy decisions around influenza treatment and prevention. We present a novel methodology using locally generated data for estimating this burden. METHODS AND FINDINGS: This method begins with calculating the hospitalized severe acute respiratory illness (SARI incidence for children <5 years old and persons ≥5 years old from population-based surveillance in one province. This base rate of SARI is then adjusted for each province based on the prevalence of risk factors and healthcare-seeking behavior. The percentage of SARI with influenza virus detected is determined from provincial-level sentinel surveillance and applied to the adjusted provincial rates of hospitalized SARI. Healthcare-seeking data from healthcare utilization surveys is used to estimate non-hospitalized influenza-associated SARI. Rates of hospitalized and non-hospitalized influenza-associated SARI are applied to census data to calculate the national number of cases. The method was field-tested in Kenya, and validated in Guatemala, using data from August 2009-July 2011. In Kenya (2009 population 38.6 million persons, the annual number of hospitalized influenza-associated SARI cases ranged from 17,129-27,659 for children <5 years old (2.9-4.7 per 1,000 persons and 6,882-7,836 for persons ≥5 years old (0.21-0.24 per 1,000 persons, depending on year and base rate used. In Guatemala (2011 population 14.7 million persons, the annual number of hospitalized cases of influenza-associated pneumonia ranged from 1,065-2,259 (0.5-1.0 per 1,000 persons among children <5 years old and 779-2,252 cases (0.1-0.2 per 1,000 persons for persons ≥5 years old, depending on year and base rate used. In both countries, the number of non-hospitalized influenza-associated cases was several-fold higher than the hospitalized cases. CONCLUSIONS: Influenza virus was associated with a substantial amount

    Full Text Available Metagenomics which combines the power of genomics, bioinformatics, and systems biology, provide new access to the microbial world. Metagenomics permit the genetic analysis of complex microbial populations without requiring prior cultivation. Through the conceptual innovations in metagenomics and the improvements in DNA high-throughput sequencing and bioinformatics analysis technology, gastrointestinal microbiology has entered the metagenomics era and become a hot topic worldwide. Human microbiome research is underway, however, most studies in this area have focused on the composition and function of the intestinal microbiota and the relationship between intestinal microbiota and metabolic diseases (obesity, diabetes, metabolic syndrome, etc. and intestinal disorders [inflammatory bowel disease, colorectal cancer, irritable bowel syndrome (IBS, etc.]. Few investigations on microbiota have been conducted within the upper gastrointestinal tract (esophagus, stomach and duodenum. The upper gastrointestinal microbiota is essential for several gastrointestinal illnesses, including esophagitis, Barrett’s esophagus, and esophageal carcinoma, gastritis and gastric cancer, small intestinal bacterial overgrowth, IBS and celiac disease. However, the constitution and diversity of the microbiota in different sections of the upper gastrointestinal tract under health and various disease states, as well as the function of microbiota in the pathogenesis of various digestive diseases are still undefined. The current article provides an overview of the recent findings regarding the relationship between upper gastrointestinal microbiota and gastrointestinal diseases; and discusses the study limitations and future directions of upper gastrointestinal microbiota research.

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

  9. Reirradiation to the abdomen for gastrointestinal malignancies

    Reirradiation to the abdomen could potentially play a role in palliation of symptoms or local control in patients with gastrointestinal malignancies. Our goal was to retrospectively determine rates of toxicity, freedom from local progression and overall survival in gastrointestinal cancer patients treated with reirradiation to the abdomen. Between November 2002 and September 2008, 13 patients with a prior history of abdominal radiotherapy (median dose 45 Gy) were treated with reirradiation for recurrent or metastatic gastrointestinal malignancies. The median interval between the two courses of radiotherapy was 26 months. Patients were treated with a hyperfractionated accelerated regimen, using 1.5 Gy fractions twice daily, with a median dose of 30 Gy (range 24-48 Gy). Concurrent chemotherapy was administered to 8 (62%) patients. The 1-year rate of freedom from local progression was 50%, and the median duration of freedom from local progression was 14 months. The 1-year rate of overall survival was 62%, and the median duration of overall survival was 14 months. One patient developed grade 3 acute toxicity (abdominal pain and gastrointestinal bleeding), requiring hospitalization during radiotherapy; subsequently, that patient experienced a grade 4 late toxicity (gastrointestinal bleeding). No other patients developed grade 3-4 acute or late toxicity or required hospitalization during radiotherapy. Hyperfractionated accelerated reirradiation to the abdomen was well-tolerated with low rates of acute and late toxicity. Reirradiation could play a role in providing a limited duration of local control in gastrointestinal cancer patients with a history of prior abdominal radiotherapy

  12. Effects of radiation upon gastrointestinal motility

    Mary F Otterson

    2007-01-01

    Whether due to therapeutic or belligerent exposure, the gastrointestinal effects of irradiation produce symptoms dreaded by a majority of the population. Nausea, vomiting, diarrhea and abdominal cramping are hallmarks of the prodromal phase of radiation sickness, occurring hours to days following radiation exposure. The prodromal phase is distinct from acute radiation sickness in that the absorptive, secretory and anatomic changes associated with radiation damage are not easily identifiable. It is during this phase of radiation sickness that gastrointestinal motility significantly changes. In addition, there is evidence that motor activity of the gut contributes to some of the acute and chronic effects of radiation.

  14. Critical illness neuropathy

    Vijayan J

    2005-01-01

    Full Text Available The neuromuscular syndrome of acute limb and respiratory weakness that commonly accompanies patients with multi-organ failure and sepsis constitutes critical illness polyneuropathy. It is a major cause of difficulty in weaning off the patient from the ventilator after respiratory and cardiac causes have been excluded. It is usually an axonal motor-sensory polyneuropathy, and is usually associated with or accompanied with a coma producing septic encephalopathy. The neuropathy is usually not apparent until the patient′s encephalopathy has peaked, and may be noted only when the brain dysfunction is resolving. Patients usually have a protracted hospital course complicated by multi-organ failure and the systemic inflammatory response syndrome. Elevated serum glucose levels and reduced albumin are risk factors for nerve dysfunction, as is prolonged intensive care unit stay. Polyneuropathy may develop after only one week of the systemic inflammatory response syndrome, but the frequency tends to correlate with the duration of the severe illness.

    Samer EllahhamSamer Ellahham and Associates, Falls Church, VA, USAAbstract: Hyperglycemia frequently occurs with acute medical illness, especially among patients with cardiovascular disease, and has been linked to increased morbidity and mortality in critically ill patients. Even patients who are normoglycemic can develop hyperglycemia in response to acute metabolic stress. An expanding body of literature describes the benefits of normalizing hyperglycemia with insulin therapy in hospitalized...

  19. Illness representations in patients with hand injury.

    Chan, Jeffrey C Y

    2009-07-01

    Differences in illness perception about hand injury may partly explain the variation in health behaviours such as adherence to post-operative therapy, coping strategy, emotional response and eventual clinical outcome. This study examined the illness perception of patients with hand injuries in the acute trauma setting.

    Dengue often presents with non-specific clinical signs, and given the current paucity of accurate, rapid diagnostic laboratory tests, identifying easily obtainable bedside markers of dengue remains a priority. Previous studies in febrile Asian children have suggested that the combination of a positive tourniquet test (TT) and leucopenia can distinguish dengue from other febrile illnesses, but little data exists on the usefulness of these tests in adults or in the Americas. We evaluated the di...

Consenso SEMICYUC-SENPE: Cirugía del aparato digestivo

    C. Sánchez Álvarez

    2011-11-01

    Full Text Available Gastrointestinal surgery and critical illness place tremendous stress on the body, resulting in a series of metabolic changes that may lead to severe malnutrition, which in turn can increase postsurgical complications and morbidity and mortality and prolong the hospital length of stay. In these patients, parenteral nutrition is the most widely used form of nutritional support, but administration of enteral nutrition early in the postoperative period is effective and well tolerated, reducing infectious complications, improving wound healing and reducing length of hospital stay. Calorie-protein requirements do not differ from those in other critically-ill patients and depend on the patient's underlying process and degree of metabolic stress. In patients intolerant to enteral nutrition, especially if the intolerance is due to increased gastric residual volume, prokinetic agents can be used to optimize calorie intake. When proximal sutures are used, tubes allowing early jejunal feeding should be used. Pharmaconutrition is indicated in these patients, who benefit from enteral administration of arginine, omega 3 and RNA, as well as parenteral glutamine supplementation. Parenteral nutrition should be started in patients with absolute contraindication for use of the gastrointestinal tract or as complementary nutrition if adequate energy intake is not achieved through the enteral route.El estrés de la cirugía gastrointestinal y la enfermedad crítica representan una gran agresión sobre el organismo, lo que ocasiona una serie de cambios metabólicos que pueden conducir a una situación de desnutrición grave, con aumento de las complicaciones posquirúrgicas, mayor morbimortalidad y prolongación de la estancia hospitalaria. En estos enfermos la nutrición parenteral es la más utilizada, pero se ha visto que la nutrición enteral administrada de forma precoz en el postoperatorio es efectiva y bien tolerada, con disminución de las complicaciones

FONTES DE DADOS: Livros-textos e publicações indexadas no Medline e SciELO nos últimos 20 anos, utilizando-se as palavras chaves: "mesenteric artery", "superior mesenteric artery", "newborn intestinal circulation", "necrotizing enterocolitis", "doppler flow velocimetry". SÍNTESE DOS DADOS: Alterações do fluxo sanguíneo mesentérico são um dos fatores predisponentes da enterocolite necrosante, doença neonatal de alta morbimortalidade que acomete principalmente prematuros. A circulação mesentérica é peculiar no período neonatal tanto em relação ao seu estado basal, quanto à sua resposta frente a estímulos fisiológicos. Variações da irrigação mesentérica podem ser inerentes à própria fase de desenvolvimento vascular intestinal do recém-nascido pré-termo, com possíveis agravos de fatores perinatais como: insuficiência placentária, asfixia, infecção, cateterismo umbilical, drogas (indometacina e cafeína, fototerapia, alimentação artificial e progressão rápida da dieta. A dopplerfluxometria permite o estudo da irrigação de órgãos-alvo e pode quantificar o fluxo sanguíneo, a resistência vascular e predizer situações de risco para doenças do trato gastrintestinal no período neonatal. CONCLUSÕES: O recém-nascido apresenta peculiaridades de irrigação sanguínea gastrintestinal. A dopplerfluxometria da artéria mesentérica superior é um método não invasivo que determina as condições circulatórias no território intestinal.OBJECTIVE:To describe peculiarities of the neonatal mesenteric circulation and to characterize the susceptibility factors to the development of gastrointestinal illnesses and alterations of the superior mesenteric artery

  8. Usefulness of the helical CT in gastro intestinally caused acute abdomen; Utilidad de la TC helicoidal en el abdomen agudo de origen gastrointestinal

    At present, there is a vivid debate on the role of the Helical CT (HCT) in the acute abdomen, principally on the usefulness of the non contrast HCT. We aim to present the most common semiological findings and the differential diagnoses, and to give a short description of the indications and protocols, according to the existing literature and to our experience with HCT during the last three years. We believe that the generalization of the use of HCT in emergencies avoid unnecessary surgery and shorten observation times on many occasions, with clear benefits in the clinical management of the patients.

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

The recent literature describing zinc action on gastrointestinal epithelial tight junctions and epithelial barrier function is described. Zinc enhancement of gastrointestinal epithelial barrier function may figure prominently in its potential therapeutic action in several gastrointestinal diseases.

  13. Is the irradiated small bowel volume still a predictor for acute lower gastrointestinal toxicity during preoperative concurrent chemo-radiotherapy for rectal cancer when using intensity-modulated radiation therapy?

    The small bowel (SB) represents the most important dose-limiting structure in pelvic radiotherapy (RT). However, we observed that the majority of rectal cancer patients who received preoperative pelvic intensity modulated RT (IMRT) developed acute tenesmus without watery diarrhea. The objective of this study is to determine if the RT dose to SB affects the acute lower gastrointestinal toxicity (ALGIT) in rectal cancer patients who received neoadjuvant concurrent chemotherapy-IMRT. We will also evaluate if patient and tumor factors affect the ALGIT. We retrospectively analyzed 63 rectal cancer patients that consecutively received preoperative IMRT (45 Gy for pelvis and 50 Gy for gross tumor in 25 fractions) with concurrent chemotherapy (oxaliplatin 130 mg/m2 on day 1 and capecitabine 825 mg/m2, twice per day from day 1 to day 14, week 1 and 4) between May 2012 and May 2013. The ALGIT was assessed with Common Terminology Criteria for Adverse Events version 3. The patients were stratified into two groups (with and without grade ≥2 ALGIT). The effect of SB volume receiving 5 to 40 Gy (V5 to V40) at a 5 Gy interval dose level on grade ≥2 ALGIT was evaluated. The volume of small bowel is defined as the volume of the small bowel loop. Other factors evaluated include patient’s age and gender, tumor size and location and preexisting number of daily bowel movements. Overall, grade ≥2 ALGIT occurred in 57 % (36/63) patients. There was no significant difference between the two groups of patients (with and without grade ≥2 ALGIT) in SB V5 to V40, patient’s age and gender, tumor location and preexisting number of daily bowel movements. There was a significant difference between the two groups of patients in tumor volume (with grade ≥2 ALGIT: 115.5 ± 85.5 cm3 versus without grade ≥2 ALGIT: 58.5 ± 25.2 cm3, p = 0.0001). Multivariate analysis revealed no association between the dose SB received (V5 to V40) and the grade ≥2 ALGIT after adjusting for the tumor

  14. Nurses’ knowledge of the principles of acute pain assessment in critically ill adult patients who are able to self-report

    2016-01-01

    Conclusion: The nurses had adequate general knowledge about the principles of acute pain assessment in CIAP. However, some knowledge gaps exist about key concepts in pain assessment and these can curtail the efforts to ensure quality pain assessment and management in CIAP. The findings entrench the need for focused professional training and continuing professional education about best practices for pain assessment and management in CIAP.

  19. Onset of efficacy with acute long-acting injectable paliperidone palmitate treatment in markedly to severely ill patients with schizophrenia: post hoc analysis of a randomized, double-blind clinical trial

    2011-01-01

    Background This post hoc analysis (trial registration: ClinicalTrials.gov NCT00590577) assessed onset of efficacy and tolerability of acute treatment with once-monthly paliperidone palmitate (PP), a long-acting atypical antipsychotic initiated by day 1 and day 8 injections, in a markedly to severely ill schizophrenia population. Methods Subjects entering the 13-week, double-blind trial were randomized to PP (39, 156, or 234 mg [25, 100, and 150 mg eq of paliperidone, respectively]) or placebo. This subgroup analysis included those with a baseline Clinical Global Impressions-Severity (CGI-S) score indicating marked to severe illness. PP subjects received a 234-mg day 1 injection (deltoid), followed by their assigned dose on day 8 and monthly thereafter (deltoid or gluteal). Thus, data for PP groups were pooled for days 4 and 8. Measures included Positive and Negative Syndrome Scale (PANSS), CGI-S, Personal and Social Performance (PSP), and adverse events (AEs). Analysis of covariance (ANCOVA) and last-observation-carried-forward (LOCF) methodologies, without multiplicity adjustments, were used to assess changes in continuous measures. Onset of efficacy was defined as the first time point a treatment group showed significant PANSS improvement (assessed days 4, 8, 22, 36, 64, and 92) versus placebo, which was maintained through end point. Results A total of 312 subjects met inclusion criterion for this subgroup analysis. After the day 1 injection, mean PANSS total scores improved significantly with PP (all received 234 mg) versus placebo at day 4 (P = 0.012) and day 8 (P = 0.007). After the day 8 injection, a significant PANSS improvement persisted at all subsequent time points in the 234-mg group versus placebo (P < 0.05). PANSS improvements were greater from day 36 through end point in the 156-mg group (P < 0.05) and only at end point in the 39-mg group (P < 0.05). CGI-S and PSP scores improved significantly in the 234-mg and 156-mg PP groups versus placebo at end

  20. The devil is in the detail: Acute Guillain-Barré syndrome camouflaged as neurosarcoidosis in a critically ill patient admitted to an Intensive Care Unit

    Pooja Prathapan Sarada

    2016-01-01

    Full Text Available Guillain-Barré syndrome (GBS is an acute demyelinating polyneuropathy, usually evoked by antecedent infection. Sarcoidosis is a multisystem chronic granulomatous disorder with neurological involvement occurring in a minority. We present a case of a 43-year-old Caucasian man who presented with acute ascending polyradiculoneuropathy with a recent diagnosis of pulmonary sarcoidosis. The absence of acute flaccid paralysis excluded a clinical diagnosis of GBS in the first instance. Subsequently, a rapid onset of proximal weakness with multi-organ failure led to the diagnosis of GBS, which necessitated intravenous immunoglobulin and plasmapheresis to which the patient responded adequately, and he was subsequently discharged home. Neurosarcoidosis often masquerades as other disorders, leading to a diagnostic dilemma; also, the occurrence of a GBS-like clinical phenotype secondary to neurosarcoidosis may make diagnosing coexisting GBS a therapeutic challenge. This article not only serves to exemplify the rare association of neurosarcoidosis with GBS but also highlights the need for a high index of clinical suspicion for GBS and accurate history taking in any patient who may present with rapidly progressing weakness to an Intensive Care Unit.

    Chronic glutamine supplementation reduces exercise-induced intestinal permeability and inhibits the NF-κB pro-inflammatory pathway in human peripheral blood mononuclear cells. These effects were correlated with activation of HSP70. The purpose of this paper is to test if an acute dose of oral glutamine prior to exercise reduces intestinal permeability along with activation of the heat shock response leading to inhibition of pro-inflammatory markers. Physically active subjects (N = 7) completed baseline and exercise intestinal permeability tests, determined by the percent ratio of urinary lactulose (5 g) to rhamnose (2 g). Exercise included two 60-min treadmill runs at 70 % of VO2max at 30 °C after ingestion of glutamine (Gln) or placebo (Pla). Plasma levels of endotoxin and TNF-α, along with peripheral blood mononuclear cell (PBMC) protein expression of HSP70 and IκBα, were measured pre- and post-exercise and 2 and 4 h post-exercise. Permeability increased in the Pla trial compared to that at rest (0.06 ± 0.01 vs. 0.02 ± 0.018) and did not increase in the Gln trial. Plasma endotoxin was lower at the 4-h time point in the Gln vs. 4 h in the Pla (6.715 ± 0.046 pg/ml vs. 7.952 ± 1.11 pg/ml). TNF-α was lower 4 h post-exercise in the Gln vs. Pla (1.64 ± 0.09 pg/ml vs. 1.87 ± 0.12 pg/ml). PBMC expression of IkBα was higher 4 h post-exercise in the Gln vs. 4 h in the Pla (1.29 ± 0.43 vs. 0.8892 ± 0.040). HSP70 was higher pre-exercise and 2 h post-exercise in the Gln vs. Pla (1.35 ± 0.21 vs. 1.000 ± 0.000 and 1.65 ± 0.21 vs. 1.27 ± 0.40). Acute oral glutamine supplementation prevents an exercise-induced rise in intestinal permeability and suppresses NF-κB activation in peripheral blood mononuclear cells. PMID:25062931

    We describe real-world psychopharmacological treatment in a Japanese, male, closed psychiatric unit where clozapie was still unavailable. Fifty-five persistently-ill patients with schizophrenia (ICD-10), mean ± S.D. age: 57.5 ± 13.0 y.o., duration of illness and admissions: 30.9 ± 15.2 years and 20.7 ± 14.5 years, respectively) treated longitudinally were evaluated. The rule was to treat with a simplest possible psychotropic regimen without polypharmacy. Compared to the baseline, the number and dose of antipsychotics were reduced from 1.9 to 1.1 and 1012 mg/day to 607 mg/day, respectively. The number of total psychotropics was minimized from 4.7 to 2.1, with a simplified once or twice daily dosing. Overall, the CGI-Severity and FACT-Sz (global functioning) improved slightly from 5.8 to 5.5 and 28.7 to 32.6, respectively. Of note, no patients got worse in comparison with the baseline clinical presentation. Forty-four patients were successfully treated with a single antipsychotic; only seven needed two antipsychotics simultaneously while 36 had been treated with antipsychotic polypharmacy at baseline. Benzodiazepines (mostly lorazepam) and antiparkinsonian drugs were prescribed in 28 and only two, respectively. Nineteen needed adjunctive valproate (average blood levels: 99.3 ± 21.8 μg/mL) and nine used lithium (0.61 ± 0.26 mEq/L). Optimization of psychopharmacotherapy is still possible for difficult-to-treat patients and, while augmentation of an antipsychotic with mood stabilizers is frequently needed, antipsychotic polypharmacy should be exceptional.

    Objective: To investigate the mechanism of gastrointestinal motility disorders in severe acute pancreatitis (SAP) and the related effects of Qingyi decoction administration.Methods: Forty-eight SD rats were randomized into sham operation group, SAP model group (model group) and SAP model with Qingyi decoction treatment group (Qingyi decoction treatment group). The SAP model was created by multi-point uniform injection of S% sodium taurocholate beneath the pancreatic capsule, and rats in Qingyi decoction treatment group were given Qingyi decoction by gavage, while rats in sham operation group and model group were treated with normal saline of the same volume instead. Twenty-four hours after operation, the interdigestive myoelectric complex (IMC) of the gastric antrum of rats was recorded by using bipolar silver electrodes, the serum concentration of motilin (MTL) and vasoactive intestinal peptide (VIP) were measureed by ELISA assay, and the pathological observation and scoring of the pancreatic tissues were performed. Results: Compared with sham operation group, both model group and Qingyi decoction treatment group presented with decreased MTL level and increased VIP level (all P<0.05), but the degrees of MTL reduction and VIP elevation in Qingyi decoction treatment group were lower than those in model group, and the pathological score of Qingyi decoction treatment group was also lower than that of model group (all P<0.05). The time periods of IMC cycle and phase Ⅰ and Ⅱ were prolonged but those of IMC phase Ⅲ were shortened, and the amplitude and frequency of phase Ⅲ peak potential in both model group and Qingyi decotion treatment group decreased in comparison with sham operation group (all P<0.05), but all these IMC indices in Qingyi decoction treatment group altered less than those in model group (all P<0.05). Correlation analysis showed that the IMC phase Ⅲ time in SAP rat was positively correlated with MTL concentration (r=0.967, P<0.05), while

    Dengue often presents with non-specific clinical signs, and given the current paucity of accurate, rapid diagnostic laboratory tests, identifying easily obtainable bedside markers of dengue remains a priority. Previous studies in febrile Asian children have suggested that the combination of a positive tourniquet test (TT) and leucopenia can distinguish dengue from other febrile illnesses, but little data exists on the usefulness of these tests in adults or in the Americas. We evaluated the diagnostic accuracy of the TT and leucopenia (white blood cell count AFI) surveillance study conducted in the Emergency Department of Saint Luke's Hospital in Ponce, Puerto Rico. From September to December 2009, 284 patients presenting to the ED with fever for 2–7 days and no identified source were enrolled. Participants were tested for influenza, dengue, leptospirosis and enteroviruses. Thirty-three (12%) patients were confirmed as having dengue; 2 had dengue co-infection with influenza and leptospirosis, respectively. An infectious etiology was determined for 141 others (136 influenza, 3 enterovirus, 2 urinary tract infections), and 110 patients had no infectious etiology identified. Fifty-two percent of laboratory-positive dengue cases had a positive TT versus 18% of patients without dengue (PAFI outbreaks, the absence of leucopenia combined with a negative tourniquet test may be useful to rule out dengue.

    Nonvariceal upper gastrointestinal bleeding (NUGB) remains a major medical problem even after advances in medical therapy with gastric acid suppression and cyclooxygenase (COX-2) inhibitors. Although the incidence of upper gastrointestinal bleeding presenting to the emergency room has slightly decreased, similar decreases in overall mortality and rebleeding rate have not been experienced over the last few decades. Many causes of upper gastrointestinal bleeding have been identified and will be reviewed. Endoscopic, radiographic and angiographic modalities continue to form the basis of the diagnosis of upper gastrointestinal bleeding with new research in the field of CT angiography to diagnose gastrointestinal bleeding. Endoscopic and angiographic treatment modalities will be highlighted, emphasizing a multi-modality treatment plan for upper gastrointestinal bleeding. (orig.)

    2006-01-01

    The role of gastrointestinal hormones in the regulation of appetite is reviewed. The gastrointestinal tract is the largest endocrine organ in the body. Gut hormones function to optimize the process of digestion and absorption of nutrients by the gut. In this capacity, their local effects on gastrointestinal motility and secretion have been well characterized. By altering the rate at which nutrients are delivered to compartments of the alimentary canal, the control of food intake arguably cons...

    Introduction: Acute acalculous cholecystitis (AAC) is a serious disease, difficult to diagnose in critically ill patients. The aim of the study was to evaluate the diagnostic performances of abdominal ultrasonography (US) and morphine-augmented cholescintigraphy (MC) and to improve diagnostic strategy in patients of intensive care unit (ICU) with suspected AA C. Methods: We retrospectively studied 82 consecutive ICU patients with suspected AA C. US was positive if the triad of gallbladder distension, gallbladder wall thickening and sludge was found. MC was positive if the gallbladder remained non-visualized after morphine injection. In a second time, other scintigraphic criteria of interpretation were tested, according to the visualization of the gallbladder before or after morphine administration. Treatment was decided on the basis of clinical, laboratory and imaging data. Results: The diagnosis of AAC was retained in 34 patients. US and MC had respectively for the diagnosis of AAC a sensitivity of 20.6 and 70.6%, and a specificity of 95.8 and 100%. Interpreting the MC as positive if the gallbladder remains non-visualized after morphine, as negative if it appears before, and as non-conclusive if visualized after, makes it possible to define respectively patients with high probability (100%), with low probability (7.5%) or with intermediate probability (39%) of AAC. Conclusions: MC is better than US for diagnosing AAC in critically ill patients, having in particular excellent specificity using the classical criteria of interpretation. MC must be thus performed in patients at risk for AAC, determined with clinical, laboratory and eventually echographic findings. To decrease false negative rate of MC, a probability categorical classification is proposed to improve patients' care. (author)

  12. Clinical and radiological features of pandemic H1N1 2009 influenza virus infection manifesting as acute febrile respiratory illness at their initial presentations: comparison with contemporaneous non-H1N1 patients

    Background Since the first outbreak caused by the pandemic H1N1 2009 influenza in Mexico, the virus has spread widely across the world with meaningful morbidity and mortality. However, there are few data on the comparative investigations to assess the clinical and radiological features between the H1N1 patient and non-H1N1 patients. Purpose To assess the clinical and radiological features of patients infected by the pandemic H1N1 2009 flu virus at their initial presentation and to compare them with contemporaneous non-H1N1 patients with acute febrile respiratory illness. Material and Methods This retrospective study was approved by the ethics committee of the Armed Forces Medical Command, South Korea. From August to September 2009, 337 consecutive patients presented with an acute febrile respiratory illness in a tertiary military hospital. Reverse-transcriptase polymerase-chain-reaction tests were performed in 62 of these patients under the impression of H1N1 infection. Clinical and radiological features at their initial presentation were described for the H1N1 group (n = 35) and non-H1N1 group (n = 27) and compared between the two groups. Results Increased C-reactive protein level (97%) without leukocytosis (9%) or increased erythrocyte sedimentation rate (0%) was common in the H1N1 group at their initial presentation. On chest radiographs, 12 of 35 (34%) H1N1 patients had abnormal findings; nodules in 10 patients (83%) and consolidations in two (17%). Of the 28 H1N1 patients who underwent thin-section CT 16 patients (57%) showed abnormal findings; ground-glass opacities (GGOs) in 15 (94%), and nodules in 13 (81%). However, there were no significant differences between the H1N1 group and non-H1N1 group in terms of symptoms, laboratory results, or radiological findings (P > 0.05). Conclusion Patients with H1N1 infection show consistent clinical and radiological features at their initial presentation, however, clinical and radiological features of the H1N1 group are

    Full Text Available Abstract Background Urinary tract infection (UTI is common in children, and may cause serious illness and recurrent symptoms. However, obtaining a urine sample from young children in primary care is challenging and not feasible for large numbers. Evidence regarding the predictive value of symptoms, signs and urinalysis for UTI in young children is urgently needed to help primary care clinicians better identify children who should be investigated for UTI. This paper describes the protocol for the Diagnosis of Urinary Tract infection in Young children (DUTY study. The overall study aim is to derive and validate a cost-effective clinical algorithm for the diagnosis of UTI in children presenting to primary care acutely unwell. Methods/design DUTY is a multicentre, diagnostic and prospective observational study aiming to recruit at least 7,000 children aged before their fifth birthday, being assessed in primary care for any acute, non-traumatic, illness of ≤ 28 days duration. Urine samples will be obtained from eligible consented children, and data collected on medical history and presenting symptoms and signs. Urine samples will be dipstick tested in general practice and sent for microbiological analysis. All children with culture positive urines and a random sample of children with urine culture results in other, non-positive categories will be followed up to record symptom duration and healthcare resource use. A diagnostic algorithm will be constructed and validated and an economic evaluation conducted. The primary outcome will be a validated diagnostic algorithm using a reference standard of a pure/predominant growth of at least >103, but usually >105 CFU/mL of one, but no more than two uropathogens. We will use logistic regression to identify the clinical predictors (i.e. demographic, medical history, presenting signs and symptoms and urine dipstick analysis results most strongly associated with a positive urine culture result. We will

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

    Gastrointestinal tract is the most common extranodal site involved by lymphoma with the majority being non-Hodgkin type. Although lymphoma can involve any part of the gastrointestinal tract, the most frequent sites in order of its occurrence are the stomach followed by small intestine and ileocecal region. Gastrointestinal tract lymphoma is usually secondary to the widespread nodal diseases and primary gastrointestinal tract lymphoma is relatively rare. Gastrointestinal lymphomas are usually not clinically specific and indistinguishable from other benign and malignant conditions. Diffuse large B-cell lymphoma is the most common pathological type of gastrointestinal lymphoma in essentially all sites of the gastrointestinal tract, although recently the frequency of other forms has also increased in certain regions of the world. Although some radiological features such as bulky lymph nodes and maintenance of fat plane are more suggestive of lymphoma, they are not specific,thus mandating histopathological analysis for its definitive diagnosis. There has been a tremendous leap in the diagnosis, staging and management of gastrointestinal lymphoma in the last two decades attributed to a better insight into its etiology and molecular aspect as well as the knowledge about its critical signaling pathways.

    Objective To discuss the superiority of the gastrointestinal anastomat in surgical treatment of acute perforation of gastroduodenal ulce (APPU) with subtotal gastrectomy. Methods 1067 cases of APPU were analyzed retrospectively in our emergency center from Jan 1995 to Dec 2010.739 patients undergoing subtotal gastrectomy were divided into two groups,appliance group (anastomat anastomosis) with 526 cases and handiwork group (handiwork anastomosis) with 213 cases. In appliance group,485 cases were operated by Billroth I operation,34 cases by Billroth II operation and 2 cases by Roux-en-y stomach intestine anastomosis. In handiwork group, 194 cases were operated by Billroth I operation, 15 cases by Billroth H operation and 4 cases by Roux-en-y stomach intestine anastomosis. Results Differences were significant in mean time of operation and mean functional recovery time of stomach intestine between the appliance group [ (105.0±18.2) min,(41.2±6.4) h] and the handiwork group [(154.0+35.1) min, (65. 6±12. 4) h] ( P < 0.01). Two cases of stomal leak, no case of anastomotic stenosis and 5 cases of bleeding in stoma were found in appliance group. Five cases of stomal leak,2 cases of anastomotic stenosis and 4 cases of bleeding in stoma were found in handiwork group. The complications in handiwork group were significantly lower than those in handiwork group (P < 0. 01). Conclusion The use of gastrointestinal anastomat can shorten operating time and functional recovery time of stomach intestine, which can reduce postoperative complications.%目的 探讨胃肠吻合器在消化性溃疡急性穿孔行胃大部切除手术中的应用价值.方法 1995年1月至2010年12月我院急救中心外科收治的消化性溃疡急性穿孔行胃大部切除术患者739例,其中器械吻合组526例(Billroth Ⅰ术式治疗485例,BillrothⅡ式34例,Roux-en-y胃肠吻合7例),手工吻合组213例(Billroth Ⅰ术式治疗194例,BillrothⅡ式15例,Roux-en-y胃肠吻合4例).结

  20. Pancreatic Involvement in Critically ill Patients

    Abhinav Agrawal

    2015-07-01

    Full Text Available Elevation of pancreatic enzymes is often observed in patients admitted to intensive care units in the United States. Elevated pancreatic enzymes can occur due to acute pancreatitis or numerous non-specific reasons. Non-specific enzyme elevation can be seen in patients with head injury, acute renal failure, diabetic ketoacidosis or patients on hemodialysis. Patients with severe acute pancreatitis can be admitted to the intensive care units for intensive care or patients admitted to the intensive care units for other critical illness can develop acute pancreatitis due to a variety of reasons like ischemia, hypoperfusion, drugs or hypercalcemia. It can be a challenging task to distinguish between acute pancreatitis and non-specific enzyme elevation, especially in critically ill patients with multiple co-morbidities admitted to the intensive care units in whom historical information may not be always available. In addition, the clinical consequences of pancreatic enzyme elevation in the critically ill patients are also not very clear. This review attempts to describe the complex interplay of various factors that can lead to either pancreatic inflammation and/or pancreatic enzyme elevation in the critically ill patients along with the clinical consequences and approach to patient with pancreatic enzyme elevation in the intensive care units.

Methods The clinical data of 125 cases patients with acute gastrointestinal dysfunction were retrospectively analyzed. The risk factors possibly influencing the prognosis were analyzed by multivariate statistical Logistic analysis. Results Among 125 children patients, 61 cases died, and the mortality rate was 48.8%. Logistic regression analysis indicated that poor circulation, cardiovascular system failure, hepatic failure, brain failure were significant risk factors of death associated with acute gastrointestinal dysfunction. (OR = 4.156, 3.330, 6.903, P<0.05 or<0.01). Conclusions Poor circulation, cardiovascular system failure, hepatic failure and brain failure are significant risk factors of death associated with acute gastrointestinal dysfunction.

  5. Differential acute postprandial effects of processed meat and isocaloric vegan meals on the gastrointestinal hormone response in subjects suffering from type 2 diabetes and healthy controls: a randomized crossover study.

    Lenka Belinova

    Full Text Available The intake of meat, particularly processed meat, is a dietary risk factor for diabetes. Meat intake impairs insulin sensitivity and leads to increased oxidative stress. However, its effect on postprandial gastrointestinal hormone (GIH secretion is unclear. We aimed to investigate the acute effects of two standardized isocaloric meals: a processed hamburger meat meal rich in protein and saturated fat (M-meal and a vegan meal rich in carbohydrates (V-meal. We hypothesized that the meat meal would lead to abnormal postprandial increases in plasma lipids and oxidative stress markers and impaired GIH responses.In a randomized crossover study, 50 patients suffering from type 2 diabetes (T2D and 50 healthy subjects underwent two 3-h meal tolerance tests. For statistical analyses, repeated-measures ANOVA was performed.The M-meal resulted in a higher postprandial increase in lipids in both groups (p<0.001 and persistent postprandial hyperinsulinemia in patients with diabetes (p<0.001. The plasma glucose levels were significantly higher after the V-meal only at the peak level. The plasma concentrations of glucose-dependent insulinotropic peptide (GIP, peptide tyrosine-tyrosine (PYY and pancreatic polypeptide (PP were higher (p<0.05, p<0.001, p<0.001, respectively and the ghrelin concentration was lower (p<0.001 after the M-meal in healthy subjects. In contrast, the concentrations of GIP, PYY and PP were significantly lower after the M-meal in T2D patients (p<0.001. Compared with the V-meal, the M-meal was associated with a larger increase in lipoperoxidation in T2D patients (p<0.05.Our results suggest that the diet composition and the energy content, rather than the carbohydrate count, should be important considerations for dietary management and demonstrate that processed meat consumption is accompanied by impaired GIH responses and increased oxidative stress marker levels in diabetic patients.ClinicalTrials.gov NCT01572402.

  6. Probiotics in critically ill children.

    Singhi, Sunit C; Kumar, Suresh

    2016-01-01

    Gut microflora contribute greatly to immune and nutritive functions and act as a physical barrier against pathogenic organisms across the gut mucosa. Critical illness disrupts the balance between host and gut microflora, facilitating colonization, overgrowth, and translocation of pathogens and microbial products across intestinal mucosal barrier and causing systemic inflammatory response syndrome and sepsis. Commonly used probiotics, which have been developed from organisms that form gut microbiota, singly or in combination, can restore gut microflora and offer the benefits similar to those offered by normal gut flora, namely immune enhancement, improved barrier function of the gastrointestinal tract (GIT), and prevention of bacterial translocation. Enteral supplementation of probiotic strains containing either Lactobacillus alone or in combination with Bifidobacterium reduced the incidence and severity of necrotizing enterocolitis and all-cause mortality in preterm infants. Orally administered Lactobacillus casei subspecies rhamnosus, Lactobacillus reuteri, and Lactobacillus rhamnosus were effective in the prevention of late-onset sepsis and GIT colonization by Candida in preterm very low birth weight infants. In critically ill children, probiotics are effective in the prevention and treatment of antibiotic-associated diarrhea. Oral administration of a mix of probiotics for 1 week to children on broad-spectrum antibiotics in a pediatric intensive care unit decreased GIT colonization by Candida, led to a 50% reduction in candiduria, and showed a trend toward decreased incidence of candidemia. However, routine use of probiotics cannot be supported on the basis of current scientific evidence. Safety of probiotics is also a concern; rarely, probiotics may cause bacteremia, fungemia, and sepsis in immunocompromised critically ill children. More studies are needed to answer questions on the effectiveness of a mix versus single-strain probiotics, optimum dosage regimens

  7. Probiotics in critically ill children

    Gut microflora contribute greatly to immune and nutritive functions and act as a physical barrier against pathogenic organisms across the gut mucosa. Critical illness disrupts the balance between host and gut microflora, facilitating colonization, overgrowth, and translocation of pathogens and microbial products across intestinal mucosal barrier and causing systemic inflammatory response syndrome and sepsis. Commonly used probiotics, which have been developed from organisms that form gut microbiota, singly or in combination, can restore gut microflora and offer the benefits similar to those offered by normal gut flora, namely immune enhancement, improved barrier function of the gastrointestinal tract (GIT), and prevention of bacterial translocation. Enteral supplementation of probiotic strains containing either Lactobacillus alone or in combination with Bifidobacterium reduced the incidence and severity of necrotizing enterocolitis and all-cause mortality in preterm infants.

  8. Diagnosing gastrointestinal illnesses using fecal headspace volatile organic compounds.

    Chan, Daniel K; Leggett, Cadman L; Wang, Kenneth K

    2016-01-28

    Volatile organic compounds (VOCs) emitted from stool are the components of the smell of stool representing the end products of microbial activity and metabolism that can be used to diagnose disease. Despite the abundance of hydrogen, carbon dioxide, and methane that have already been identified in human flatus, the small portion of trace gases making up the VOCs emitted from stool include organic acids, alcohols, esters, heterocyclic compounds, aldehydes, ketones, and alkanes, among others. These are the gases that vary among individuals in sickness and in health, in dietary changes, and in gut microbial activity. Electronic nose devices are analytical and pattern recognition platforms that can utilize mass spectrometry or electrochemical sensors to detect these VOCs in gas samples. When paired with machine-learning and pattern recognition algorithms, this can identify patterns of VOCs, and thus patterns of smell, that can be used to identify disease states. In this review, we provide a clinical background of VOC identification, electronic nose development, and review gastroenterology applications toward diagnosing disease by the volatile headspace analysis of stool.

    2013-01-01

    Editors' Summary Background Acute gastrointestinal bleeding is a potentially life-threatening abdominal emergency that remains a common cause of admission to hospital. Upper gastrointestinal bleeding (bleeding derived from a source above the ligament of Treitz, which connects the fourth portion of the duodenum to the diaphragm) is roughly four times as common as bleeding from the lower gastrointestinal tract and is a major cause of morbidity and mortality. Upper gastrointestinal bleeding is a...

  11. Acute Gynecologic Disorders.

    Donaldson, Carolyn K

    2015-11-01

    Premenopausal women with acute pelvic pain comprise a significant percentage of patients who present to the emergency room. Etiologies can be gynecologic, urologic, gastrointestinal, or vascular. Signs and symptoms are often nonspecific and overlapping. The choice of imaging modality is determined by the clinically suspected differential diagnosis. Ultrasound (US) is the preferred imaging modality for suspected obstetric or gynecologic disorders. CT is more useful when gastrointestinal or urinary tract pathology is likely. MR imaging is rarely used in the emergent setting, except to exclude appendicitis in pregnant women. This article presents a comprehensive review of imaging of acute gynecologic disorders.

    1985-01-01

    The development of flexible fibers for the delivery of laser energy led to the first endoscopic laser applications in humans in the early 1970s. Since that time, much has been learned about applications throughout the gastrointestinal tract. The risks appear to be minimal. The coagulative effect of laser energy is used to treat gastrointestinal hemorrhage and small, benign mucosal lesions. The ablative effect of the Nd:YAG laser on tissue is used for palliative therapy for malignant gastroint...

  17. Catastrophic gastrointestinal complication of systemic immunosuppression.

    Smith, Lyn Alexandra; Gangopadhyay, Mitali; Gaya, Daniel R

    2015-02-28

    We present a case of acute upper gastrointestinal haemorrhage in a patient with systemic vasculitis immunosuppressed on cyclophosphamide and prednisolone. The patient presented with a diffuse haemorrhagic oesophagitis and a non-specific duodenitis. Biopsies taken from the oesophagus and duodenum demonstrated infection with herpes simplex virus (HSV) and cytomegalovirus (CMV) respectively. Viral infection of the upper gastrointestinal tract is a recognised complication of immunosuppression and HSV is one of the most common pathogens. CMV on the other hand most commonly causes a colitis or less commonly oesophagitis. CMV enteritis is rare as is the synchronous infection with two viral agents in an immunocompromised patient having being described in a few case series only. Viral infection of the gastrointestinal tract in immunocompromised patients should be treated with systemic anti-viral medication and consideration to withdrawal of the immunosuppressive therapy if possible and appropriate. The authors highlight the need for a high suspicion of viral infection in immunosuppressed patients presenting with upper gastrointestinal bleeding. PMID:25741165

We explore the association between Candida and such vasculopathy.

  20. Treatment of Nonvariceal Gastrointestinal Hemorrhage by Transcatheter Embolization

    Purpose. To investigate the sensitivity of mesenteric angiography, technical success of hemostasis, clinical success rate, and complications of transcatheter embolization for the treatment of acute nonvariceal gastrointestinal hemorrhage. Material and Methods. A retrospective review of 200 consecutive patients who underwent mesenteric arteriography for acute nonvariceal gastrointestinal hemorrhage between February 2004 and February 2011 was done. Results. Of 200 angiographic studies, 114 correctly revealed the bleeding site with mesenteric angiography. 47 (41%) patients had upper gastrointestinal hemorrhage and 67 (59%) patients had lower gastrointestinal hemorrhage. Out of these 114, in 112 patients (98%) technical success was achieved with immediate cessation of bleeding. 81 patients could be followed for one month. Clinical success was achieved in 72 out of these 81 patients (89%). Seven patients rebled. 2 patients developed bowel ischemia. Four patients underwent surgery for bowel ischemia or rebleeding. Conclusion. The use of therapeutic transcatheter embolization for treatment of acute gastrointestinal hemorrhage is highly successful and relatively safe with 98% technical success and 2.4% postembolization ischemia in our series. In 89% of cases it was definitive without any further intervention

  3. Obesity and gastrointestinal neoplasms

    Izabela Binkowska-Borgosz

    2014-10-01

    Full Text Available Being overweight or obese is a significant public health problem in the 21st century due to its scale, common existence and its cause-effect association with multiple diseases. Excessive accumulation of adipose tissue in humans is regarded as a major risk factor for development of cardiovascular and skeletal diseases. However, data from recent years have revealed that obesity is also strongly associated with increased risk of the majority of cancers in humans, including those originating from the gastrointestinal tract. During the last few year this association has been thoroughly proven and supported by several epidemiological analyses. The authors present i the current state of knowledge regarding key (pathomechanisms that link metabolism of human adipose tissue to development/progression of neoplasms (especially in the gastrointestinal tract, as well as ii the results of selected clinical studies in which the influence of obesity on risk of gastrointestinal cancer development has been addressed.

    2016-01-01

    As of 20 May 2016 there have been 28,646 cases and 11,323 deaths resulting from the West African Ebola virus disease (EVD) outbreak reported to the World Health Organization. There continue to be sporadic flare-ups of EVD cases in West Africa.EVD presentation is nonspecific and characterized initially by onset of fatigue, myalgias, arthralgias, headache, and fever; this is followed several days later by anorexia, nausea, vomiting, diarrhea, and abdominal pain. Anorexia and gastrointestinal losses lead to dehydration, electrolyte abnormalities, and metabolic acidosis, and, in some patients, acute kidney injury. Hypoxia and ventilation failure occurs most often with severe illness and may be exacerbated by substantial fluid requirements for intravascular volume repletion and some degree of systemic capillary leak. Although minor bleeding manifestations are common, hypovolemic and septic shock complicated by multisystem organ dysfunction appear the most frequent causes of death.Males and females have been equally affected, with children (0-14 years of age) accounting for 19 %, young adults (15-44 years) 58 %, and older adults (≥45 years) 23 % of reported cases. While the current case fatality proportion in West Africa is approximately 40 %, it has varied substantially over time (highest near the outbreak onset) according to available resources (40-90 % mortality in West Africa compared to under 20 % in Western Europe and the USA), by age (near universal among neonates and high among older adults), and by Ebola viral load at admission.While there is no Ebola virus-specific therapy proven to be effective in clinical trials, mortality has been dramatically lower among EVD patients managed with supportive intensive care in highly resourced settings, allowing for the avoidance of hypovolemia, correction of electrolyte and metabolic abnormalities, and the provision of oxygen, ventilation, vasopressors, and dialysis when indicated. This experience emphasizes that

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

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

  6. Gastrointestinal variant of Lemierre's syndrome complicating ruptured appendicitis

    Fadi Al Akhrass

    2015-01-01

    Full Text Available Fusobacterium necrophorum is a non-spore-forming, obligate anaerobic, filamentous, gramnegative bacillus that frequently colonizes the human oral cavity, respiratory tract, and gastrointestinal tract. Fusobacterium species have rarely been implicated in cases of gastrointestinal variant of Lemierre's syndrome. We describe a case of F. necrophorum bacteremia associated with suppurative porto-mesenteric vein thrombosis (PVT following acute ruptured appendicitis. In addition, we list the documented twelve cases of Fusobacterium pylephlebitis. Recanalization of the porto-mesenteric veins and relief of the extrahepatic portal hypertension were achieved with early empiric antibiotic and local thrombolytic therapy. Our patient's case underscores the importance of recognizing Fusobacterium bacteremia as a possible cause of suppurative PVT after disruption of the gastrointestinal mucosa following an acute intraabdominal infectious process. Early treatment of this condition using anticoagulation and endovascular thrombolysis as adjunctive therapies may prevent PVT complications.

  11. Disaster related heat illness

    Explained and discussed are the outline of heat illness (HI), its raised risk and measures taken at the disaster of the Fukushima Nuclear Power Plant Accident (FNPPA; Mar. 2011). High temperature and humid environment induce HI through the fervescence and dehydration resulting in the intestinal ischemia/hypoxia and organ failure. Epidemiologic data of the heatstroke in Japan suggest its seemingly parallel incidence to seasonal hotness of the summer. HI is classified in either classical (non-exertional) or exertional heatstroke, both with severity of I (slight), II (slight symptom of the central nervous system (CNS); necessary for consultation) and III (most serious; having dysfunction of CNS, organ or coagulation). Therapy depends on the severity: I for the first aid on site, II necessary for carrying to hospital and III for hospitalization. Protection is possible by personal, neighbors' and managers' carefulness, and supply of sufficient water and minerals. Risk of HI was suddenly raised at taking measures to meet with the FNPPA. Japanese Association for Acute Medicine (JAAM) promptly organized JAAM-FNPPA Working Group to treat the emergent multiple incidents including the radiation exposure and HI as well. Exertional HI was mainly in labors wearing rather sealed closes to protect radiation to work for steps of the Accident, and which was similar to evacuees temporarily entering the evacuation area for visit to their own vacant houses. In the summer, classical HI was also a problem mainly in elderly living in the evacuation dwellings. Document of HI incidents and patients at FNPPA should be recorded for the reference to possible disaster in future. (T.T.)

  12. Five dramas of illness.

    Frank, Arthur W

    2007-01-01

    First-person narratives of illness experience are dramatic: the narrator, who is also the sufferer, is caught in conflicts of forces that permit understanding more than control. Among the dramas of illness, five occur frequently in autobiographical accounts of illness. These dramas overlap and have varying emphases in different people's stories. They are the drama of genesis (what instigated the illness); the drama of emotion work (what emotional displays are required or prohibited); the drama of fear and loss; the drama of meaning; and finally, the drama of self. This five-drama framework can focus critical and clinical attention on which conflicting forces the ill person is working to reconcile, what makes that work difficult, and how conceiving of one's illness as a drama can be a source of meaning and value.

  14. Haemochromatosis and gastrointestinal cancer.

    Lagergren, Katarina; Wahlin, Karl; Mattsson, Fredrik; Alderson, Derek; Lagergren, Jesper

    2016-10-15

    Iron overload in patients with haemochromatosis is a strong risk factor for liver cancer, but its influence on other gastrointestinal cancer risk is unclear. The aim was to assess the relative risk of luminal gastrointestinal cancer among patients diagnosed with haemochromatosis. This population-based, nationwide Swedish cohort study included patients with haemochromatosis in Sweden in 1965-2013. The incidence of gastrointestinal cancers was assessed through the Swedish Cancer Registry. The measure of relative risk was the standardised incidence ratio (SIR) with 95% confidence interval (CI), that is, the ratio of the observed number of gastrointestinal cancers in the haemochromatosis cohort divided by the expected number of such cancers, calculated from the entire corresponding background population of Sweden. Among 6,849 patients in the haemochromatosis cohort with up to 48 years of follow-up, the SIRs were 3-fold increased for oesophageal squamous cell carcinoma (SIR = 3.2, 95% CI 1.3-6.6; n = 7) and 40% increased for colon adenocarcinoma (SIR = 1.4, 95% CI 1.1-1.9; n = 54). No associations were found between haemochromatosis and the risk of adenocarcinoma of the oesophagus (SIR = 0.5, 95% CI 0.0-2.5; n = 1), stomach (SIR = 0.7, 95% CI 0.3-1.4; n = 8), small bowel (SIR = 1.2, 95% CI 0.0-6.7; n = 1) or rectum (SIR = 1.0, 95% CI 0.6-1.6; n = 21). These findings indicate that haemochromatosis increases the risk of oesophageal squamous cell carcinoma and colon adenocarcinoma, but might not influence the risk of other types of luminal gastrointestinal cancer. These findings should encourage further research examining the role of iron overload in cancer aetiology. PMID:27300578

  15. Mood disorder associated with gastrointestinal and liver diseases: are there many challenges

    With the high prevalence of hepatitis and other gastrointestinal illness in the country, we come across the mental health consequences of such medical problems. The major issues are with depression and anxiety. It is quite understandable that physical illnesses bring in with them stress that is intrinsic by virtue of the serious nature of medical illness, the socio-economical repercussions and the uncertain prognosis in terms of the nature of illness. The major mental health problem that these patients are referred with is depression that can be of moderate to severe intensity. Depression in itself is a separate clinical entity that calls for treatment. (author)

    menor costo fueron razones frecuentemente aducidas para estas elecciones. Conclusiones. Esta información puede resultar útil para mejorar la comunicación con las madres.Objective. To identify the terms used by mothers to refer to diseases, signs and symptoms related to acute respiratory illnesses (ARI, alarming signs which should motivate them to seek medical attention, and to describe common home practices of disease care and treatment. Material and methods. An ethnographic study was performed in six rural communities of the Mexican central highlands. Interviews were collected from 12 key informers, six mothers of children who had died from ARI and 24 mothers of children younger than five years of age, with several ethnographic techniques to complement information ("triangulation". Results. The most commonly identified diseases were cold, sore throat, cough, bronchitis, pneumonia and "broncomonía". Key signs to establish diagnosis included nasal discharge, sore throat, cough, head and body ache, fever, "bubbling" chest, general malaise and shortness of breath. Tachypnea was referred to as "b breathing", "much breathing", "rapid breathing" or "sizzle"; intercostal depression as "the chest sinks", stridor as "chest moan or chest snore", sibilance as "chest snore" and cyanosis as "he turns purple". Home treatments include herbal teas, lemon, green or red tomato or potato applied to the throat externally, as well as creams applied to chest or back. Antibiotic prescription was not common, contrary to antipiretics. Most mothers recognized mild illnesses: severe illnesses were recognized less frequently. When faced with a severe ARI, mothers sought attention firstly at the project clinic, second in frequency with a private physician in the capital of the province and then at the Health Ministry of the district. The reasons to choose these possibilities were mainly proximity and lower costs. Conclusions. This information can be useful to improve communication with mothers.

  17. Acute Brucellosis Presenting as Gastroenteritis: Case Report

    Salih Bin Salih; Adel Alothman

    2013-01-01

    Brucellosis is a systemic infection with multiple presentations. In spite of its oral mode of transmission and gastrointestinal pathogenesis, systemic symptoms are usually more prominent than gastrointestinal ones. Acute brucellosis presenting as gastroenteritis is rare in adults and could be the only manifestation of the disease. We report a case of gastroenteritis caused by Brucella species.

    Burini Roberto; de Oliveira Erick

    2011-01-01

    Abstract Among athletes strenuous exercise, dehydration and gastric emptying (GE) delay are the main causes of gastrointestinal (GI) complaints, whereas gut ischemia is the main cause of their nausea, vomiting, abdominal pain and (blood) diarrhea. Additionally any factor that limits sweat evaporation, such as a hot and humid environment and/or body dehydration, has profound effects on muscle glycogen depletion and risk for heat illness. A serious underperfusion of the gut often leads to mucos...

  1. Prokinetic Effect of Polyherbal Formulation on Gastrointestinal Tract

    D Srinivasan

    2009-01-01

    Full Text Available PHF, a polyherbal formulation, consist of seven known herbs namely, Aegle marmelos, Elettaria cardamomum, Glycyrrhiza glabra, Citrus aurantifolia, Rosa damascene, Cissus quadrangularis and Saccharum officinarum. The PHF was evaluated for acute toxicity, gastrointestinal motility and gastric emptying rate in mice and rats. Based on acute toxicity study, the PHF was considered as safe and 3 dose (100, 200 and 400 mg/kg levels were employed for further pharmacological studies. The gastrointestinal prokinetics effect of PHF in various dose levels (100, 200 and 400 mg/kg., p.o was studied by charcoal meal gastrointestinal transit and laxative effect in mice. The gastric emptying rate of PHF in rat was studied by disappearance of phenol red from stomach. The results illustrate that PHF at 200 and 400 mg/kg significantly (p< 0.001 enhanced the gastrointestinal transit. PHF at 400 mg/kg (p< 0.01 significantly enhanced the purging index, which is the measure of laxative activity. PHF at 200 mg/kg (p< 0.05 less significantly enhanced the purging index. In gastric emptying rate, PHF dose dependently increased the gastric emptying. From the above findings, PHF may be used as gastrointestinal prokinetics and to improve the intestinal motility.

  6. [Zinc and gastrointestinal disorders].

    Higashimura, Yasuki; Takagi, Tomohisa; Naito, Yuji

    2016-07-01

    Zinc, an essential trace element, affects immune responses, skin metabolism, hormone composition, and some sensory function, so that the deficiency presents various symptoms such as immunodeficiency and taste obstacle. Further, the zinc deficiency also considers as a risk of various diseases. Recent reports demonstrated that -20% of the Japanese population was marginally zinc deficiency, and over 25% of the global population is at high risk of zinc deficiency. In gastrointestinal disorders, zinc plays an important role in the healing of mucosal and epithelial damage. In fact, polaprezinc, a chelate compound of zinc and L-carnosine, has been used for the treatment of gastric ulcer and gastritis. We describe here the therapeutic effect of zinc on gastrointestinal disorders. PMID:27455800

  7. Aeromonas caviae septicemia in immunocompetent gastrointestinal carriers

    M. Dwivedi

    2008-12-01

    Full Text Available Aeromonas caviae strains have been isolated from blood and stool cultures of three immunocompetent patients, residents of Northern India, who presented with community acquired septicemia without any recent history of diarrhea. Cell culture infectivity test performed on Hep-2 cells have shown substantial degree of invasiveness in the isolated strains. This case unleashes a possibility of asymptomatic gastrointestinal carriage of such strains of A. caviae in a very large population of India, as several areas of India have very high rates of Aeromonas induced acute diarrhea/gastroenteritis (up to 13%. It needs to be appraised further in India as well as other countries having high rates of Aeromonas induced acute diarrhea/gastroenteritis.

  10. Gastrointestinal food allergies.

    Heine, Ralf G

    2015-01-01

    Gastrointestinal food allergies present during early childhood with a diverse range of symptoms. Cow's milk, soy and wheat are the three most common gastrointestinal food allergens. Several clinical syndromes have been described, including food protein-induced enteropathy, proctocolitis and enterocolitis. In contrast with immediate, IgE-mediated food allergies, the onset of gastrointestinal symptoms is delayed for at least 1-2 hours after ingestion in non-IgE-mediated allergic disorders. The pathophysiology of these non-IgE-mediated allergic disorders is poorly understood, and useful in vitro markers are lacking. The results of the skin prick test or measurement of the food-specific serum IgE level is generally negative, although low-positive results may occur. Diagnosis therefore relies on the recognition of a particular clinical phenotype as well as the demonstration of clear clinical improvement after food allergen elimination and the re-emergence of symptoms upon challenge. There is a significant clinical overlap between non-IgE-mediated food allergy and several common paediatric gastroenterological conditions, which may lead to diagnostic confusion. The treatment of gastrointestinal food allergies requires the strict elimination of offending food allergens until tolerance has developed. In breast-fed infants, a maternal elimination diet is often sufficient to control symptoms. In formula-fed infants, treatment usually involves the use an extensively hydrolysed or amino acid-based formula. Apart from the use of hypoallergenic formulae, the solid diets of these children also need to be kept free of specific food allergens, as clinically indicated. The nutritional progress of infants and young children should be carefully monitored, and they should undergo ongoing, regular food protein elimination reassessments by cautious food challenges to monitor for possible tolerance development.

  11. The gastrointestinal endocrine system

    Track, Norman S.

    1980-01-01

    Gastrointestinal endocrinology is the study of the hormonal regulation of digestion. A number of characterized polypeptide hormones have been localized in specific gastroenteropancreatic endocrine cells. The fact that some of these hormones are also found in nerve and brain cells has given rise to the concept of a gut-brain axis. The functional capacities of these endocrine cells are determined by their anatomic location; the luminal exposure of gastroenteric endocrine cells represents an add...

    2008-01-01

    Full Text Available Abstract Background Tolerance to enteral nutrition in the critically ill child with shock has not been studied. The purpose of the study was to analyze the characteristics of enteral nutrition and its tolerance in the critically ill child with shock and to compare this with non-shocked patients. Methods A prospective, observational study was performed including critically ill children with shock who received postpyloric enteral nutrition (PEN. The type of nutrition used, its duration, tolerance, and gastrointestinal complications were assessed. The 65 children with shock who received PEN were compared with 461 non-shocked critically ill children who received PEN. Results Sixty-five critically ill children with shock, aged between 21 days and 22 years, received PEN. 75.4% of patients with shock received PEN exclusively. The mean duration of the PEN was 25.2 days and the maximum calorie intake was 79.4 kcal/kg/day. Twenty patients with shock (30.7% presented gastrointestinal complications, 10 (15.4% abdominal distension and/or excessive gastric residue, 13 (20% diarrhoea, 1 necrotising enterocolitis, and 1 duodenal perforation due to the postpyloric tube. The frequency of gastrointestinal complications was significantly higher than in the other 461 critically ill children (9.1%. PEN was suspended due to gastrointestinal complications in 6 patients with shock (9.2%. There were 18 deaths among the patients with shock and PEN (27.7%. In only one patient was the death related to complications of the nutrition. Conclusion Although most critically ill children with shock can tolerate postpyloric enteral nutrition, the incidence of gastrointestinal complications is higher in this group of patients than in other critically ill children.

    2007-10-01

    Full Text Available We describe a surgical emergency due to GI-bleeding caused by gastrointestinal autonomic nerve tumours (GANT's in a patient with von Recklinghausen's disease. A 72 year old female patient with von Recklinghausen's disease was admitted with maelena. Endoscopy showed no active bleeding in the stomach and the colon. Therefore an angio-CT-scan was performed which revealed masses of the proximal jejunum as source of bleeding. Laparotomy was indicated and a 20 cm segment of jejunum which carried multiple extraluminal tumours was resected. The source of the bleeding was a 2 cm tumour which had eroded the mucosal surface. Immunohistologically, evidence of neuronal differentiation could be shown in the spindle-formed cells with positive staining for C-Kit (CD 117, CD 34, and a locally positive staining for synaptophysine and S100. This case report illustrates the association between neurofibromatosis and stromal tumours and should alert surgeons and gastroenterologist about gastrointestinal manifestations in patients with von Recklinghausen's disease.Se describe una urgencia quirúrgica por sangrado intestinal debido a tumor gastrointestinal de nervios autónomos (GANT asociado a enfermedad de von Recklinghausen. Una mujer de 72 años con neurofibromatosis fue ingresada con signos de melena. La endoscopia digestiva alta y baja fue negativa. Se indicó TAC con contraste que advirtió tumores yeyunales como causa del sangrado. Se realizó laparotomía y resección de un segmento de 20 cm de yeyuno que incluía varios tumores. La causa del sangrado activo fue lesión en mucosa intestinal por erosión tumoral. El análisis por inmunohistoquímica de la pieza mostró diferenciación neuronal, con células fusiformes con tinción positiva para el C-Kit (CD 117, CD 34. Esta nota clínica pone de manifiesto la asociación entre la neurofibromatosis y los tumores estromales y debe alertar a gastroenterólogos y cirujanos sobre las posibles manifestaciones

  20. Osteoporosis in Gastrointestinal Diseases.

    Krela-Kaźmierczak, Iwona; Szymczak, Aleksandra; Łykowska-Szuber, Liliana; Eder, Piotr; Linke, Krzysztof

    2016-01-01

    Secondary osteoporosis occurs as an isolated pathology or co-exists with types I and II osteoporosis. The gastroenterologist may come across osteoporosis or osteopenia in a patient with a gastrointestinal disease. This is often a young patient in whom investigations should be carried out and appropriate treatment initiated, aimed at preventing bone fractures and the formation of the best peak bone mass. Osteoporosis occurs in patients with the following conditions: Crohn's disease, ulcerative colitis, celiac disease, post gastrectomy patients, patients with short bowel syndrome, chronic hepatitis and cirrhosis, treated with steroids (steroid-induced osteoporosis) and patients using proton pump inhibitors chronically (state of achlorhydria). It is therefore necessary to approve a list of risk factors of secondary osteoporosis, the presence of which would be an indication for screening for osteoporosis, including a DXA study and the development of a separate algorithm for the therapeutic management of secondary osteoporosis accompanying gastrointestinal diseases, especially in premenopausal young women and young men, because there are currently no registered drugs with proven antifracture activity for this group of patients.

    Malnutrition is a common comorbidity that places inpatients at risk of complications, infections, long length of stay, higher costs, and increased mortality. Thus, nutrition support has become an important therapeutic adjunctive to the care of these patients. For patients unable to feed themselves, nutrition can be delivered via the parenteral or enteral routes. The formulations used to deliver nutrients and the route of nutrient delivery, absorption, and processing differ substantially between parenteral and enteral nutrition. Over the past two decades, many randomised clinical trials have assessed the effects of parenteral versus enteral nutrition on outcomes (ie, complications, infections, length of stay, costs, mortality) in diverse inpatient populations. From a search of medical publications, studies were selected that assessed important clinical outcomes of parenteral versus enteral feeding or intravenous fluids in patients with trauma/burn injuries, surgery, cancer, pancreatic disease, inflammatory bowel disease, critical illness, liver failure, acute renal failure, and organ transplantation. Our goal was to determine the optimum route of feeding in these patient groups. The available evidence lends support to the use of enteral over parenteral feeding in inpatients with functioning gastrointestinal tracts. PMID:16581410

  2. Munchausen syndrome mimicking psychiatric disease with concomitant genuine physical illness

    Almeida, Jaime; da Silva, Joaquim Alves; Xavier, Miguel; Gusmão, Ricardo

    2010-01-01

    Munchausen syndrome is a disorder in which patients intentionally produce symptoms mimicking physical or psychiatric illnesses with the aim to assume the sick role and to gain medical attention. Once a patient receives a Munchausen syndrome diagnosis every complaint made thence tends to be regarded with scepticism by clinical staff. However, it is possible that a bona fide illness, which might be disregarded, may coexist in these patients. We report a case of MS mimicking psychiatric disease with concomitant genuine acute physical illness. Despite the initial doubts about the veracity of the latter, due to its prompt recognition, treatment was successful. PMID:22798096

  4. Homeopathy for the treatment of gastrointestinal disorders in children

    Taiana Markoski; Cassia Virginia Garcia

    2011-01-01

    Background: Colic and diarrhea are among the most common gastrointestinal disorders in childhood, which manifest spontaneously and acute. The allopathic treatment consists, in most cases, in the administration of the association homatropine-dimethicone to relieve colic, and oral rehydration and loperamide in cases of diarrhea [1,2]. The ineffectiveness of the conventional treatment and the possible adverse effects they may cause have led to increase the demand from children’ parents fo...

  5. Development of Gastrointestinal Function: Risk Factors for Necrotizing Enterocolitis

    Clark, David A.; Mitchell, Amy L.

    2004-01-01

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

Despite this, less than 20% of patients wh...

  7. Early Psychological Therapy in Critical Illness.

    Karnatovskaia, Lioudmila V; Philbrick, Kemuel L; Parker, Ann M; Needham, Dale M

    2016-02-01

    Survivors of critical illness often experience long-lasting impairments in mental, cognitive, and physical functioning. Acute stress reactions and delusional memories appear to play an important role in psychological morbidity following critical illness, and few interventions exist to address these symptoms. This review elucidates acute psychological stressors experienced by the critically ill. The effects of psychological stress and state of mind on disease are discussed using examples from the non-intensive care unit (ICU) literature, including a review of placebo and nocebo effects. After reviewing the effect of the mind on both psychological and physiological outcomes, we then focus on the role of memories-including their malleable nature and the consequences of false memories. Memory may play a role in the genesis of subsequent psychological trauma. Traumatic memories may begin forming even before the patient arrives in the ICU and during their state of unconsciousness in the ICU. Hence, practical interventions for redirecting patients' thoughts, such as positive suggestion techniques and actively involving patients in the treatment process as early as possible, are worthy of further investigation.

The paper's focus is on how issues of gender and class intersect in the negotiation of illness among welfare officers and clients. The particular client group in question consists...... of individuals that are defined by their lack of a bio-medical diagnosis. Their ‘lack’ of identity accentuates how gender and class become central in the categorisation practices, constructing the ill person as either bio-medically sick or as a person who may be suffering but only from diffuse...... psychological problems. The paper shows that it is predominantly poorly educated women without a bio-medical diagnosis that welfare officers describe as suffering from psychological problems despite the fact that the women themselves focus on physical ailments in their illness stories.

  9. The gastrointestinal tract

    Bartels, Else M.; Harrison, Adrian Paul

    2009-01-01

    The gastrointestinal tract (GIT) has always been and remains a major source of interest in terms of both its function, and its malfunction. Our current knowledge of age-related changes in this system, as well as drug-food interactions, however, remains relatively limited. Paradoxically, the GIT is...... not one of the core battery of tests that pharmaceutical companies are obliged to investigate as part of drug development. This review aims to cover the basics of GIT function before highlighting aspects of relevance for safety pharmacology in terms of age, cancerogenesis, and noth drug and diet......-related GIT damage and dysfunction. New and novel aspects of drug delivery and drug-dietary supplement interactions are discusses and much needed areas of focus in terms of drug GIT testing are identified....

  10. Fucosylation and gastrointestinal cancer

    Kenta Moriwaki, Eiji Miyoshi

    2010-04-01

    Full Text Available Fucose (6-deoxy-L-galactose is a monosaccharide that is found on glycoproteins and glycolipids in verte-brates, invertebrates, plants, and bacteria. Fucosylation, which comprises the transfer of a fucose residue to oligosaccharides and proteins, is regulated by many kinds of molecules, including fucosyltransferases, GDP-fucose synthetic enzymes, and GDP-fucose transporter(s. Dramatic changes in the expression of fucosylated oligosaccharides have been observed in cancer and inflammation. Thus, monoclonal antibodies and lectins recognizing cancer-associated fucosylated oligosaccharides have been clinically used as tumor markers for the last few decades. Recent advanced glycomic approaches allow us to identify novel fucosylation-related tumor markers. Moreover, a growing body of evidence supports the functional significance of fucosylation at various pathophysiological steps of carcinogenesis and tumor progression. This review highlights the biological and medical significance of fucosylation in gastrointestinal cancer.

    2013-01-01

    The prevalence of obesity in the Japanese population has been increasing dramatically in step with the Westernization of lifestyles and food ways. Our study demonstrated significant associations between obesity and a number of gastrointestinal disorders in a large sample population in Japan. We demonstrated that reflux esophagitis and hiatal hernia were strongly related to obesity (BMI > 25) in the Japanese. In particular, obesity with young male was a high risk for these diseases. On the other hand, it has been reported that obesity is also associated with Barrett's esophagus and colorectal adenoma; however, obesity was not a risk factor for these diseases in our study. The difference of ethnicity of our subjects may partly explain why we found no data to implicate obesity as a risk factor for Barrett's esophagus. Arterial sclerosis associated with advanced age and hyperglycemia was accompanied by an increased risk of colorectal adenoma. PMID:23781242

  12. Estrogen and gastrointestinal malignancy.

    Hogan, A M

    2012-02-01

    The concept that E2 exerts an effect on the gastrointestinal tract is not new and its actions on intestinal mucosa have been investigated for at least three decades. An attempt to consolidate results of these investigations generates more questions than answers, thus suggesting that many unexplored avenues remain and that the full capabilities of this steroid hormone are far from understood. Evidence of its role in esophageal, gastric and gallbladder cancers is confusing and often equivocal. The most compelling evidence regards the protective role conferred by estrogen (or perhaps ERbeta) against the development and proliferation of colon cancer. Not only has the effect been described but also many mechanisms of action have been explored. It is likely that, along with surgery, chemotherapy and radiotherapy, hormonal manipulation will play an integral role in colon cancer management in the very near future.

  13. [Obesity and gastrointestinal motility].

    Lee, Joon Seong

    2006-08-01

    Gastrointestinal (GI) motility has a crucial role in the food consumption, digestion and absorption, and also controls the appetite and satiety. In obese patients, various alterations of GI motility have been investigated. The prevalence of GERD and esophageal motor disorders in obese patients are higher than those of general population. Gastric emptying of solid food is generally accelerated and fasting gastric volume especially in distal stomach is larger in obese patients without change in accommodation. Contractile activity of small intestine in fasting period is more prominent, but orocecal transit is delayed. Autonomic dysfunction is frequently demonstrated in obese patients. These findings correspond with increased appetite and delayed satiety in obese patients, but causes or results have not been confirmed. Therapeutic interventions of these altered GI motility have been developed using botulinum toxin, gastric electrical stimulation in obese patients. Novel agents targeted for GI hormone modulation (such as ghrelin and leptin) need to be developed in the near future. PMID:16929152

  14. Disorders of gastrointestinal hypomotility.

    Bielefeldt, Klaus; Tuteja, Ashok; Nusrat, Salman

    2016-01-01

    Ingestion and digestion of food as well as expulsion of residual material from our gastrointestinal tract requires normal propulsive, i.e. motor, function. Hypomotility refers to inherited or acquired changes that come with decreased contractile forces or slower transit. It not only often causes symptoms but also may compromise nutritional status or lead to other complications. While severe forms, such as pseudo-obstruction or ileus, may have a tremendous functional impact, the less severe forms of hypomotility may well be more relevant, as they contribute to common disorders, such as functional dyspepsia, gastroparesis, chronic constipation, and irritable bowel syndrome (IBS). Clinical testing can identify changes in contractile activity, defined by lower amplitudes or abnormal patterns, and the related effects on transit. However, such biomarkers show a limited correlation with overall symptom severity as experienced by patients. Similarly, targeting hypomotility with pharmacological interventions often alters gut motor function but does not consistently improve symptoms. Novel diagnostic approaches may change this apparent paradox and enable us to obtain more comprehensive information by integrating data on electrical activity, mechanical forces, patterns, wall stiffness, and motions with information of the flow of luminal contents. New drugs with more selective effects or more specific delivery may improve benefits and limit adverse effects. Lastly, the complex regulation of gastrointestinal motility involves the brain-gut axis as a reciprocal pathway for afferent and efferent signaling. Considering the role of visceral input in emotion and the effects of emotion on visceral activity, understanding and managing hypomotility disorders requires an integrative approach based on the mind-body continuum or biopsychosocial model of diseases.

  15. Pediatric Gastrointestinal Diseases in Nigeria: Histopathologic Analysis of 74 Cases

    Abudu

    2013-10-01

    Full Text Available BACKGROUND: Children are vulnerable to a vast number of diseases including gastrointestinal disorders, which may be associated with life threatening complications that sometimes result in mortality especially if left untreated. OBJECTIVE: To establish the age and sex distribution of children in the study population as well as the histopathological characteristics of gastrointestinal diseases that occurred in those children who were aged 14years and below in Sagamu, Southwestern Nigeria. MATERIALS AND METHODS: Demographic data such as age, sex, and clinical summary of children in the study population were extracted from the medical records of Olabisi Onabanjo University Teaching Hospital, Sagamu, Ogun State from January 2003 to December 2009. Based on this information, a review of paraffin embedded blocks and slides as well as histopathological reports of gastrointestinal diseases that occurred in those children aged 14years and below was undertaken at the Morbid Anatomy Department of the hospital. RESULTS: Seventy–four cases of gastrointestinal diseases were seen in children aged 14years and below. The majority (39.2% of gastrointestinal diseases were accounted for by appendiceal lesions. Hirschsprung’s disease, intussusceptions, enterocolitis and jejunal atresia accounted for 29.7%, 10.8%, 6.8% and 4.1% of cases respectively. Adenocarcinoma of the intestine was the predominant gastrointestinal tumour, occurring in 5 out of 7 children. Two cases of non-Hodgkin lymphoma were also seen. The ages of the children ranged from 2 to 14 years, with a mean age of 8.6years and a peak age incidence of gastrointestinal disease in the 10-14year age group. Male children were more commonly affected with the exception of appendiceal lesions, which occurred more in females (M:F ratio= 1.6:1.0. Acute suppurative appendicitis was the most prevalent lesion of the appendix, occurring in 13 out of 29 appendiceal lesions. Moderately differentiated to poorly

  20. Pancreatic and gastrointestinal trauma in children.

    Grosfeld, J L; Cooney, D R

    1975-05-01

    Injuries to the pancreas and gastrointestinal tract following blunt abdominal trauma continue to be a significant cause of morbidity and mortality in the pediatric age group. Optimal treatment of these injuries is frequently hampered by considerable delays in diagnosis. Factors contributing to these delays include the location of much of the duodenum and the pancreas in the retroperitoneum resulting in an absence of initial symptoms and signs, the often trivial nature of some of the responsible blunt traumatic accidents, inappropriate child-parent or child-physician communication, failure to achieve a meaningful physical examination in uncooperative or unconscious patients, and false negative paracentesis. Eighty per cent of these injuries occurred in boys. Eleven of 16 patients with pancreatic trauma had pseudocysts. A persistently elevated serum amylase level was invariably noted and epigastric mass was palpable in eight patients. Significant delays in diagnosis were prevalent and pseudocysts was misdiagnosed as appendicitis in three cases. Internal drainage by cystgastrostomy or cystjejunostomy was effective operative treatment. In instances of acute pancreatic injuries, sump drains, gastrostomy, cholecystostomy, and total parenteral hyperalimentation were useful therapeutic adjuncts. There was one death for a 6.2 per cent mortality rate. Forty patients had gastrointestinal injuries involving the duodenum in 17, jejunum in 14, ileum in seven, and stomach in two. Perforations occured in 65 per cent of cases, obstructing hematomas in 30 per cent, and mesenteric avulsions in 5 per cent. Associated injuries were observed in 15 patients (37.5 per cent). Pain and tenderness were the only consistent findings. Upper gastrointestinal contrast studies were diagnostic of duodenal hematomas. Eighty per cent of perforations were managed by simple closures and 20 per cent by resection and anastomosis. Obstructing hematomas unassociated with other injuries may be expected to

  1. Acute acalculous cholecystitis.

    Barie, Philip S; Eachempati, Soumitra R

    2003-08-01

    Acute cholecystitis can develop without gallstones in critically ill or injured patients. However, the development of acute acalculous cholecystitis is not limited to surgical or injured patients, or even to the intensive care unit. Diabetes, malignant disease, abdominal vasculitis, congestive heart failure, cholesterol embolization, and shock or cardiac arrest have been associated with acute acalculous cholecystitis. Children may also be affected, especially after a viral illness. The pathogenesis of acute acalculous cholecystitis is a paradigm of complexity. Ischemia and reperfusion injury, or the effects of eicosanoid proinflammatory mediators, appear to be the central mechanisms, but bile stasis, opioid therapy, positive-pressure ventilation, and total parenteral nutrition have all been implicated. Ultrasound of the gallbladder is the most accurate diagnostic modality in the critically ill patient, with gallbladder wall thickness of 3.5 mm or greater and pericholecystic fluid being the two most reliable criteria. The historical treatment of choice for acute acalculous cholecystitis has been cholecystectomy, but percutaneous cholecystostomy is now the mainstay of therapy, controlling the disease in about 85% of patients. Rapid improvement can be expected when the procedure is performed properly. The mortality rates (historically about 30%) for percutaneous and open cholecystostomy appear to be similar, reflecting the severity of illness, but improved resuscitation and critical care may portend a decreased risk of death. Interval cholecystectomy is usually not indicated after acute acalculous cholecystitis in survivors; if the absence of gallstones is confirmed and the precipitating disorder has been controlled, the cholecystostomy tube can be pulled out after the patient has recovered.

    Consumption of arsenic (As) wine is a traditional activity during the classic Chinese festival of Duanwu, colloquially known worldwide as the Dragon Boat Day. Arsenic wine is drunk on the morning of the fifth day of the fifth lunar calendar month to commemorate the death of Qu Yuan, a famed Chinese poet who drowned himself in protest of a corrupt government, and to protect against ill fortune. Although realgar minerals are characteristically composed of sparingly soluble tetra-arsenic tetra-sulfides (As{sub 4}S{sub 4}), purity does vary with up to 10% of As being present as non-sulfur bound species, such as arsenate (As{sup V}) and arsenite (As{sup III}). Despite, the renewed interest in As speciation and the bioaccessibility of the active As components in realgar based Chinese medicines, little is known about the safety surrounding the cultural practice of drinking As wine. In a series of experiments the speciation and solubility of As in a range of wines were investigated. Furthermore, a simulated gastrointestinal system was employed to predict the impact of digestive processes on As bioavailability. The predominant soluble As species found in all the wines were As{sup III} and As{sup V}. Based on typical As wine recipes employing 0.1 g realgar mL{sup -1} wine, the concentration of dissolved As ranged from ca. 100 to 400 mg L{sup -1} depending on the ethanol content of the preparation: with the As solubility found to be higher in wines with a lower proportion of ethanol. Based on a common 100 mL measure of wine with a concentration of 400 mg As L{sup -1}, the amount of soluble As would equate to around half of the acute minimal lethal dose for adults. This is likely an underestimate of the bioaccessible concentration, as a three-fold increase in bioaccessibility could be observed in the intestinal phase based on the results from the stimulated gastrointestinal system. - Research highlights: {yields} Drinking realgar wine is a traditional activity during the

  9. Recurrent Renal Cell Carcinoma with Synchronous Tumor Growth in Azygoesophageal Recess and Duodenum: A Rare Cause of Anemia and Upper Gastrointestinal Bleeding

    Vootla, Vamshidhar R.; Kashif, Muhammad; Niazi, Masooma; Nayudu, Suresh K.

    2015-01-01

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

    Continuous renal replacement therapy (CRRT) is an important treatment in critically ill children with acute kidney injury (AKI). Over the past decade, CRRT has been the preferred method of renal replacement therapy. We compared children with CRRT-treated adults with AKI in terms of return of kidney...

    Full Text Available Background: Primary non-Hodgkin′s lymphoma (NHL of the gastrointestinal (GI tract is the most common extranodal lymphoma in pediatric age group. Yet, the overall incidence is very low. The rarity of the disease as well as variable clinical presentation prevents early detection when the possibility of cure exists. Materials and Methods: We studied six cases of primary GI NHL in pediatric age group with reference to their clinical presentation, anatomic distribution and histopathologic characteristics. Results: All were males except one. Intestinal obstruction was the presenting feature in 50%. Half the cases showed ileocaecal involvement, while large bowel was involved in 16%. Histology showed four cases of diffuse large B-cell lymphoma (DLBCL, one case of Burkitt lymphoma, and one Burkitt-like lymphoma. Immunohistochemistry for Tdt, CD20, CD3, CD30, bcl2, bcl6 confirmed the morphological diagnosis. Conclusion: Pediatric GI lymphoma commonly involves the ileocaecal region and presents with intestinal obstruction. A higher prevalence of DLBCL is found compared to other series. A high proliferative index is useful in differentiating Burkitt-like lymphoma from DLBCL.

  17. Epidemiology of gastrointestinal cancer.

    Some 99,000 new cases of cancer of the colon are expected next year, an incidence rate higher than that for both cancer of the lung and cancer of the breast. Evidence from geographic pathology suggests that some environmental factors play a strong role in its etiology. Data obtained in the 1959 survey of one million people by the American Cancer Society and followed since, has failed to show correlation with any of the large number of factors listed. It is suggested that the etiology is one of multiple factors. The synergistic effect of exposure to asbestos and cigarette smoking in the production of bronchogenic carcinoma is demonstrated by data on cohorts of insulation workers. There was also a modest increase in the number of deaths from gastrointestinal cancer in asbestos workers, but smoking did not seem to act in synergistic fashion at that site, except perhaps in the esophagus. Deaths from cancer occurred almost entirely after a period of 20 years or more from initial exposure. The death rate from cancer tended to increase with duration of exposure, but a distinct rise over the expected was seen in those who had been exposed less than one year to amosite dust. PMID:4470947

  18. Gastrointestinal scanning agent

    An easily prepared radiolabeled gastrointestinal scanning agent is described. Technetium-99m has ideal characteristics for imaging the upper and lower GI tract and determining stomach emptying and intestinal transit time when used with an insoluble particulate material. For example, crystalline and amorphous calcium phosphate particles can be effectively labeled in a one-step process using sup(99m)TcO4 and SnCl2. These labeled particles have insignificant mass and when administered orally pass through the GI tract unchanged, without affecting the handling and density of the intestinal contents. Visualization of the esophageal entry into the stomach, the greater and lesser curvatures of the stomach, ejection into the duodenum, and rates of passage through the upper and lower GI tract are obtained. The slurry of sup(99m)TC particulate can be given rectally by enema. Good images of the cecum and the ascending, transverse, and descending colon are obtained. Mucosal folds and the splenic and hepatic flexures are visualized. The resilience of the large intestine is also readily visualized by pneumocolonographic techniques. (author)

    General localization of gastrointestinal bleeding through the use of labeled red blood cells may be performed in children, or (99m)Tc-pertechnetate may be used if a Meckel's diverticulum is suspected. As in adults, cholecystitis and biliary leak may be assessed in children via (99m)Tc-IDA derivatives. Gastroesophageal reflux can be evaluated by oral consumption of the child's usual diet labeled with (99m)Tc sulfur colloid. For the scintigraphic determination of pulmonary aspiration, a relatively high concentration of tracer within a drop of liquid is placed beneath the child's tongue followed by dynamic imaging of the respiratory tract. Colonic transit scintigraphy can aid in the identification and therapeutic decision-making in patients with functional fecal retention, the most common cause of chronic constipation in children. (18)F-DOPA positron emission tomography is useful for classifying pancreatic involvement in infantile hyperinsulinism as focal or diffuse, thereby differentiating between patients who should receive curative focal pancreatic resection versus those who should receive medical management. Assessment of protein-losing enteropathy can be conducted scintigraphically and, compared with fecal alpha-1 antitrypsin collection, the scintigraphic method can detect esophageal and gastric protein loss. Also, scintigraphic quantification of protein loss can be performed without the requirement for fecal collection. Intestinal inflammation in children with inflammatory bowel disease can be evaluated using (99m)Tc white blood cells. The scintigraphic method is safe, accurate, well-tolerated by children and complementary to endoscopy in most patients

    The domestic chicken is a common model organism for human biological research and of course also forms the basis of a global protein industry. Recent methodological advances have spurred the recognition of microbiomes as complex communities with important influences on the health and disease status of the host. In this minireview, we provide an overview of the current state of knowledge of the chicken gastrointestinal microbiome focusing on spatial and temporal variability, the presence and importance of human pathogens, the influence of the microbiota on the immune system, and the importance of the microbiome for poultry nutrition. Review and meta-analysis of public data showed cecal communities dominated by Firmicutes and Bacteroides at the phylum level, while at finer levels of taxonomic resolution, a phylogenetically diverse assemblage of microorganisms appears to have similar metabolic functions that provide important benefits to the host as inferred from metagenomic data. This observation of functional redundancy may have important implications for management of the microbiome. We foresee advances in strategies to improve gut health in commercial operations through management of the intestinal microbiota as an alternative to in-feed subtherapeutic antibiotics, improvements in pre- and probiotics, improved management of polymicrobial poultry diseases, and better control of human pathogens via colonization reduction or competitive exclusion strategies.
