    Severe acute pancreatitis is frequently associated with necrosis of the gland, and the principal late complication is infection of the necrosis. The gut barrier plays an important role in severe acute pancreatitis; in fact, gut barrier integrity prevents bacteria translocation resulting from an atrophic and leaky gut, and reduces the systemic inflammatory syndrome of the pancreatitis from gut atrophy. The maintenance of gut barrier integrity is one of the goals in the treatment of severe acut...

    Animals living in desert environments are forced to survive despite severe heat, intense solar radiation, and both acute and chronic dehydration. These animals have evolved phenotypes that effectively address these environmental stressors. To begin to understand the ways in which the desert-adapted rodent Peromyscus eremicus survives, reproductively mature adults were subjected to 72 h of water deprivation, during which they lost, on average, 23% of their body weight. The animals reacted via a series of changes in the kidney, which included modulating expression of genes responsible for reducing the rate of transcription and maintaining water and salt balance. Extracellular matrix turnover appeared to be decreased, and apoptosis was limited. In contrast to the canonical human response, serum creatinine and other biomarkers of kidney injury were not elevated, suggesting that changes in gene expression related to acute dehydration may effectively prohibit widespread kidney damage in the cactus mouse.

    Full Text Available Picroside II, from the herb Picrorhiza scrophulariiflora Pennell, has antioxidant and anti-inflammatory activities. However, its function on severe acute pancreatitis (SAP and molecular mechanism remains unknown. The effects of picroside II on the SAP induced by cerulean were investigated. SAP rats were treated with picroside II (25 mg/kg. The severity of SAP was evaluated by using biochemical and histological analyses. Pancreatic cancer cell PANC-1 was transfected with ptfLC3 (an indicator of autophagic activity, pcDNA3.1-NF-κB (nuclear factor kappa B, and pTZU6+1-NF-κB-shRNA and then treated with picroside II. Relative molecules related with NF-κB-dependent autophagy were detected by using Western blot. Autophagic activities were observed by phase-contrast and fluorescent microscopes. Acetylated LC3 was detected by immunoprecipitation. The results showed that picroside II treatment reduced the level of ALT, AST, NF-κB, IL-1β, IL-6, TNF-α, and SIRT1 (NAD+-dependent deacetylase and increased the level of SOD and GSH. The autophagic activity was reduced when NF-κB was silenced, and the levels of TNF-α and SIRT1 were reduced. In contrast, the overexpression of NF-κB increased autophagic activity and the level of TNF-α, which activated SIRT1. SIRT1 deacetylated LC3 and increased autophagic activities. Picroside II ameliorates SAP by improving antioxidant and anti-inflammtory activities of SAP models via NF-κB-dependent autophagy.

    Full Text Available Acute pancreatitis is an acute inflammatory process of the pancreas with variable involvement of other regional tissues or other organ systems. The severe form of the disease occurs in 10-20% of cases, and usually requires prolonged hospitalization due to a frequent local and systemic complications. Additionally, considerable mortality despite diagnostic and therapeutic advances, makes this disease a serious health problem nowadays. The aim of this study was to conduct a review of randomized controlled trials to determine differences in the efficiency between standard methods of treatment for severe acute pancreatitis and new treatment ways in terms of decreased mortality. Search of the 'Medline' database of original scientific papers and systematic review articles was made, using a combination of the following keywords: acute pancreatitis, treatment, mortality. In total 914 papers were found, published in the last 13 years; 14 of 64 randomized controlled clinical trials met the selection criteria and were eligible for inclusion. From a total of 16 papers, the conservative treatment was related to 11, which includes some of the new treatment methods, while the effects of new methods of treatment have been the subject of research in the four studies. Combined endoscopic and surgical treatment was applied in only one study. The largest sample of 290 patients was included in the study with platelet activation factor antagonist, while the smallest sample of 22 patients was used in the study that compared total parenteral with enteral nutrition. Continuous regional arterial infusion of protease inhibitors in combination with antibiotics, intravenous supplementation of alanyl-glutamine dipeptide and the early, high-volume continuous veno-venous hemofiltration showed the best results in the treatment of patients with severe acute pancreatitis. Also, the use of low molecular weight heparin and enteral nutrition significantly reduced mortality.

    To evaluate the clinical efficacy of intradermal injection of methylene blue for treatment of moderate to severe acute thoracic herpes zoster and prevention of postherpetica neuralgia in elderly patients. Sixty-four elderly patients with herpes zoster were randomized to receive a 10-day course of intradermal injection of methylene blue and lidocaine plus oral valaciclovir (group A, 32 cases) and intradermal injection of lidocaine plus oral valaciclovir (group B).Herpes evaluation index, pain rating index, incidence of postherpetic neuralgia, and comprehensive therapeutic effect were compared between the two groups at 11, 30 and 60 days after the treatment. The baseline characteristics were comparable between the two groups (all P>0.05). Compared with that in group B, the time for no new blister formation, blister incrustation and decrustation, and pain relief was significantly shortened in group A (Pmethylene blue can effectively shorten the disease course, reduce the pain intensity and prevent the development of postherpetic neuralgia in elderly patients with herpes zoster.

    Severe acute malnutrition (SAM) is associated with increased severity of common infectious diseases, and death amongst children with SAM is almost always as a result of infection. The diagnosis and management of infection are often different in malnourished versus well-nourished children. The objectives of this brief are to outline the evidence underpinning important practical questions relating to the management of infectious diseases in children with SAM and to highlight research gaps. Overall, the evidence base for many aspects covered in this brief is very poor. The brief addresses antimicrobials; antipyretics; tuberculosis; HIV; malaria; pneumonia; diarrhoea; sepsis; measles; urinary tract infection; nosocomial Infections; soil transmitted helminths; skin infections and pharmacology in the context of SAM. The brief is structured into sets of clinical questions, which we hope will maximise the relevance to contemporary practice. PMID:25475887

    Severe sepsis is critical to health and can result in acute renal failure (ARF). Tissue factor (TF) and thrombomodulin (TM) play key roles in vascular endothelial functions by helping maintain microcirculation in the kidney. Budding uninhibited by benzimidazole-1 (Bub1) plays a role in Akt and JNK signaling, which control TF and TM, respectively. We hypothesized that Bub1 could control vascular endothelial function in sepsis. The aim of this study was to determine the role of Bub1 in septic ARF. We used Mouse cecum ligation and puncture (CLP) using low Bub1 expressing (Bub1) and wild-type (Bub1) mice in vivo and lipopolysaccharide (LPS) stimulation of human aortic endothelial cell (HAEC) in vitro. Bub1 mice had a higher survival rate after CLP than Bub1. Bub1 mice had more severe ARF after CLP than Bub1 with blood biochemical and pathological analyses. TF expression in Bub1 mice and control HAEC (control) significantly increased in the septic model compared with Bub1 and Bub1 silenced HAEC (siBub1). TM expression in the control significantly decreased after LPS stimulation compared with siBub1. Akt and JNK phosphorylation of siBub1 were attenuated after LPS stimulation. Associations of Bub1 with Akt or JNK after LPS stimulation of HAEC were detected using immunoprecipitation, suggesting that Bub1 is involved in the phosphorylation of Akt and JNK after LPS stimulation. Bub1 insufficiency attenuates TF expression and reduces TM suppression by blocking Akt and JNK phosphorylation, respectively, thus leading to the prevention of ARF and death caused by sepsis.

    Full Text Available Objective: to evaluate the impact of Leiden mutation on the course of severe acute pancreatitis. Subjects and methods. One hundred and twelve people were examined. Group 1 comprised 50 patients diagnosed with severe acute pancreatitis without coagulation factor V (Leiden mutation. Group 2 included 42 patients with severe acute pancreatitis who were found to have Leiden mutation. Acute pancreatitis was first diagnosed in both groups. Group 3 consisted of 20 apparently healthy individuals (a control group. The severity of the underlying disease was determined in accordance with the clinical and laboratory parameters recommended by the I. I. Dzhanelidze Saint Petersburg Research Institute of Emergence Care. Results. This investigation revealed an association of Leiden mutation with trends in the development of acute pancreatitis. Group 2 exhibited a more severe disease: large focal pancreatic necrosis was twice more common and infectious complications developed more frequently; more aggressive and radical treatments were more often used. The patients with Leiden mutation had higher mortality rates (33% in the Leiden mutation group and 24% in the non-mutation group. Conclusion. The findings should be kept in mind in elaborating new diagnostic methods and principles in the treatment of the underlying disease and in the prevention of its complications in patients with severe acute pancreatitis. Key words: acute pancreatitis, Leiden mutation.

    We report two cases of severe acute pancreatitis; a 53-year-old man (Case 1) and a 60-year-old woman (Case 2). Case 1 was classified as ''severe'' according to the Ranson's criteria and he died of MOF on the 21st hospital day. Case 2 was classified as ''moderate'', but a large pancreatic abscess was observed by CT scan. She died of this abscess complicated with duodenal perforation on the 33rd hospital day. CT findings showed that this case was not ''moderate'' but ''severe''. Therefore, we believe that the findings of CT scan are an important factor for assessment of the severity of acute pancreatitis.

    Full Text Available BACKGROUND: We have noticed a recent rise in the incidence and severity of acute renal failure (ARF in malaria. AIM: To study the incidence, severity and outcome of ARF in malaria. SETTING and DESIGN: It is a retrospective analysis of data of one year from a tertiary medical centre in a metropolitan city. MATERIALS AND METHODS: Patients with ARF and smear positive malaria were evaluated. STATISTICAL ANALYSIS: Results were expressed as mean, range and standard deviation. RESULTS: Out of 402 detected smear positive malaria, 24 had ARF. Eighteen were of the age group 21-40 years. Plasmodium falciparum (PF was detected in 16, Plasmodium vivax in three, and mixed infection in five. Non-oliguric ARF was seen in 14. Eighteen showed severe ARF (Serum creatinine >5 mg%. Twenty-two patients needed dialysis. Prolonged ARF lasting for 2-6 weeks was seen in eight. Seventeen patients recovered completely, while seven showed fatal combination of disseminated intravascular coagulation (DIC, acute respiratory distress syndrome (ARDS, severe ARF and PF malaria. No response was seen to chloroquine and artesunate given alone and twenty patients required quinine. CONCLUSION: ARF necessitating dialysis was seen in 92% of patients with ARF in malaria. PF infection, severe ARF, DIC and ARDS were poor prognostic factors. Resistance was noted to both chloroquine and artesunate.

    Cholelithiasis is the most common cause of acute pancreatitis, accounting 35%-60% of cases. Around 15%-20% of patients suffer a severe attack with high morbidity and mortality rates. As far as treatment is concerned, the optimum method of late management of patients with severe acute biliary pancreatitis is still contentious and the main question is over the correct timing of every intervention. Patients after recovering from an acute episode of severe biliary pancreatitis can be offered alternative options in their management, including cholecystectomy, endoscopic retrograde cholangiopancreatography (ERCP) and sphincterotomy, or no definitive treatment. Delaying cholecystectomy until after resolution of the inflammatory process, usually not earlier than 6 wk after onset of acute pancreatitis, seems to be a safe policy. ERCP and sphincterotomy on index admission prevent recurrent episodes of pancreatitis until cholecystectomy is performed, but if used for definitive treatment, they can be a valuable tool for patients unfit for surgery. Some patients who survive severe biliary pancreatitis may develop pseudocysts or walled-off necrosis. Management of pseudocysts with minimally invasive techniques, if not therapeutic, can be used as a bridge to definitive operative treatment, which includes delayed cholecystectomy and concurrent pseudocyst drainage in some patients. A management algorithm has been developed for patients surviving severe biliary pancreatitis according to the currently published data in the literature. PMID:27678352

    Inhaled budesonide has been suggested as a novel prevention for acute mountain sickness. However, efficacy has not been compared with the standard acute mountain sickness prevention medication acetazolamide. This double-blind, randomized, placebo-controlled trial compared inhaled budesonide versus oral acetazolamide versus placebo, starting the morning of ascent from 1240 m (4100 ft) to 3810 m (12,570 ft) over 4 hours. The primary outcome was acute mountain sickness incidence (headache and Lake Louise Questionnaire ≥3 and another symptom). A total of 103 participants were enrolled and completed the study; 33 (32%) received budesonide, 35 (34%) acetazolamide, and 35 (34%) placebo. Demographics were not different between the groups (P > .09). Acute mountain sickness prevalence was 73%, with severe acute mountain sickness of 47%. Fewer participants in the acetazolamide group (n = 15, 43%) developed acute mountain sickness compared with both budesonide (n = 24, 73%) (odds ratio [OR] 3.5, 95% confidence interval [CI] 1.3-10.1) and placebo (n = 22, 63%) (OR 0.5, 95% CI 0.2-1.2). Severe acute mountain sickness was reduced with acetazolamide (n = 11, 31%) compared with both budesonide (n = 18, 55%) (OR 2.6, 95% CI 1-7.2) and placebo (n = 19, 54%) (OR 0.4, 95% CI 0.1-1), with a number needed to treat of 4. Budesonide was ineffective for the prevention of acute mountain sickness, and acetazolamide was preventive of severe acute mountain sickness taken just before rapid ascent.

    Acute bronchiolitis (AB) is a very common disease, with a high rate of seasonal hospitalization. Its management requires homogeneous clinical interpretations for which there are different approaches depending on the scales, none of which are properly validated today. To create an AB severity scale (ABSS) and to validate it. The development of a parameterized construct with a gradual cumulative score of respiratory rate, heart rate, respiratory effort, auscultation of wheezing and crackles, and the inspiration/expiration ratio. Also, the validation of the ABSS performed on patients diagnosed with AB, the reliability measured by observing the behavior of internal consistency, test-retest, external validity and inter-observer agreement. From a total of 290 measurements a Cronbach's reliability alpha of 0.83 was obtained; Kappa agreement index of 0.93 in the test-retest agreement, and Kappa index of 0.682 (α<0.05) for inter-observer agreement. The ABSS can be a reliable tool for measuring the severity of AB. Copyright © 2013 Asociación Española de Pediatría. Published by Elsevier Espana. All rights reserved.

    Acute diverticulitis of the colon represents a significant burden for national health systems, in terms of direct and indirect costs. Past guidelines claimed that recurrent episodes (two or more) of diverticulitis need surgery, but revised guidelines recommend an individualized approach to patients after an attack of acute diverticulitis. For these reasons, conservative treatment has become the preferred choice after an episode of diverticulitis. Thus, significant efforts are now being focused to identify the correct therapeutic approach to prevent diverticulitis relapses. Nonabsorbable antibiotics, 5-aminosalicylic acid and probiotics are currently being investigated in this way. The effectiveness and the future perspectives of these treatments are discussed herein.

    BACKGROUND: COPD is a major cause of morbidity and mortality in the United States as well as throughout the rest of the world. An exacerbation of COPD (periodic escalations of symptoms of cough, dyspnea, and sputum production) is a major contributor to worsening lung function, impairment in quality of life, need for urgent care or hospitalization, and cost of care in COPD. Research conducted over the past decade has contributed much to our current understanding of the pathogenesis and treatment of COPD. Additionally, an evolving literature has accumulated about the prevention of acute exacerbations. METHODS: In recognition of the importance of preventing exacerbations in patients with COPD, the American College of Chest Physicians (CHEST) and Canadian Thoracic Society (CTS) joint evidence-based guideline (AECOPD Guideline) was developed to provide a practical, clinically useful document to describe the current state of knowledge regarding the prevention of acute exacerbations according to major categories of prevention therapies. Three key clinical questions developed using the PICO (population, intervention, comparator, and outcome) format addressed the prevention of acute exacerbations of COPD: nonpharmacologic therapies, inhaled therapies, and oral therapies. We used recognized document evaluation tools to assess and choose the most appropriate studies and to extract meaningful data and grade the level of evidence to support the recommendations in each PICO question in a balanced and unbiased fashion. RESULTS: The AECOPD Guideline is unique not only for its topic, the prevention of acute exacerbations of COPD, but also for the first-in-kind partnership between two of the largest thoracic societies in North America. The CHEST Guidelines Oversight Committee in partnership with the CTS COPD Clinical Assembly launched this project with the objective that a systematic review and critical evaluation of the published literature by clinical experts and researchers in

    Full Text Available Episodic migraine is a common debilitating condition with significant worldwide impact. An effective management plan must include acute treatment to relieve the pain and potential disability associated with the attacks and may also include preventative treatments with an aim of decreasing attack frequency and severity in the longer term. Acute treatments must be limited to a maximum of 2-3 days a week to prevent medication overuse headache and focus on simple analgesia, non-steroidal anti-inflammatory drugs and triptans. Preventative treatments are numerous and should be considered when migraine attacks are frequent and or disabling, acute medication is failing, in special circumstances such as hemiplegic migraines or if the patient requests them. All preventative medications must be given at therapeutic doses for at least 6-8 weeks before an adequate trial can be judged ineffective. The most important factor in choosing drugs is the patient and the clinical features of their attack and treatment should be tailored to these. Relative co-morbidities will influence drug choice, as will the side effect profile and the efficacy of the drug. First line preventative drugs include ß-blockers, amitriptyline and anti-epileptic drugs such as topiramate and valproate.

    Background Acute kidney injury (AKI) is a life-threatening complication of severe rhabdomyolysis. This study was conducted to assess risk factors for AKI and to develop a risk score for early prediction. Methods Retrospective observational cohort study with a 9-year follow-up, carried out in an acute-care teaching-affiliated hospital. A total of 126 patients with severe rhabdomyolysis defined as serum creatine kinase (CK) > 5,000 IU/L fulfilled the inclusion criteria. Univariate and logistic regression analyses were performed to determine risk factors for AKI. Based on the values obtained for each variable, a risk score and prognostic probabilities were estimated to establish the risk for developing AKI. Results The incidence of AKI was 58%. Death during hospitalization was significantly higher among patients with AKI, compared to patients without AKI (19.2% vs 3.6%, p = 0.008). The following variables were independently associated with AKI: peak CK (odds ratio [OR] 4.9, 95%CI 1.4-16.8), hypoalbuminemia (rhabdomyolysis may be useful in clinical practice, particularly to implement early preventive measures.

    Acute heart failure represents the first cause of hospitalization in elderly persons and is the main determinant of the huge healthcare expenditure related to heart failure. Despite therapeutic advances, the prognosis of acute heart failure is poor, with in-hospital mortality ranging from 4% to 7%, 60- to 90-day mortality ranging from 7% to 11%, and 60- to 90-day rehospitalization from 25% to 30%. Several factors including cardiovascular and noncardiovascular conditions as well as patient-related and iatrogenic factors may precipitate the rapid development or deterioration of signs and symptoms of heart failure, thus leading to an acute heart failure episode that usually requires patient hospitalization. The primary prevention of acute heart failure mainly concerns the prevention, early diagnosis, and treatment of cardiovascular risk factors and heart disease, including coronary artery disease, while the secondary prevention of a new episode of decompensation requires the optimization of heart failure therapy, patient education, and the development of an effective transition and follow-up plan.

    Probiotics may improve a person's health by regulating their immune function. Some trials have shown that probiotic strains can prevent respiratory infections. Even though the previous version of our review showed benefits of probiotics for acute upper respiratory tract infections (URTIs), several new studies have been published. To assess the effectiveness and safety of probiotics (any specified strain or dose), compared with placebo, in the prevention of acute URTIs in people of all ages, who are at risk of acute URTIs. We searched CENTRAL (2014, Issue 6), MEDLINE (1950 to July week 3, 2014), EMBASE (1974 to July 2014), Web of Science (1900 to July 2014), the Chinese Biomedical Literature Database, which includes the China Biological Medicine Database (from 1978 to July 2014), the Chinese Medicine Popular Science Literature Database (from 2000 to July 2014) and the Masters Degree Dissertation of Beijing Union Medical College Database (from 1981 to July 2014). We also searched the World Health Organization (WHO) International Clinical Trials Registry Platform (ICTRP) and ClinicalTrials.gov for completed and ongoing trials on 31 July 2014. Randomised controlled trials (RCTs) comparing probiotics with placebo to prevent acute URTIs. Two review authors independently assessed the eligibility and quality of trials, and extracted data using the standard methodological procedures expected by The Cochrane Collaboration. We included 13 RCTs, although we could only extract data to meta-analyze 12 trials, which involved 3720 participants including children, adults (aged around 40 years) and older people. We found that probiotics were better than placebo when measuring the number of participants experiencing episodes of acute URTI [at least one episode: odds ratio (OR): 0.53; 95% CI = 0.37-0.76, P school absence (OR: 0.10; 95% CI = 0.02-0.47, very low quality evidence). Probiotics and placebo were similar when measuring the rate ratio of episodes of acute URTI (rate ratio: 0

    Full Text Available Abstract Severe acute respiratory syndrome (SARS is a new infectious disease caused by a novel coronavirus that leads to deleterious pulmonary pathological features. Due to its high morbidity and mortality and widespread occurrence, SARS has evolved as an important respiratory disease which may be encountered everywhere in the world. The virus was identified as the causative agent of SARS due to the efforts of a WHO-led laboratory network. The potential mutability of the SARS-CoV genome may lead to new SARS outbreaks and several regions of the viral genomes open reading frames have been identified which may contribute to the severe virulence of the virus. With regard to the pathogenesis of SARS, several mechanisms involving both direct effects on target cells and indirect effects via the immune system may exist. Vaccination would offer the most attractive approach to prevent new epidemics of SARS, but the development of vaccines is difficult due to missing data on the role of immune system-virus interactions and the potential mutability of the virus. Even in a situation of no new infections, SARS remains a major health hazard, as new epidemics may arise. Therefore, further experimental and clinical research is required to control the disease.

    To assess the effectiveness of resistin in predicting the severity of acute pancreatitis. Patients with acute pancreatitis who presented at the Gastroenterology Clinic, Erzurum Education and Research Hospital, Turkey were enrolled in this prospective study. White blood cell (WBC), C-reactive protein (CRP) and resistin levels were measured on admission and at 24 h, day 3 and day 7 following admission, along with other blood parameters. Patients were divided into two groups: mild acute pancreatitis and moderate/severe acute pancreatitis. Of 59 patients with acute pancreatitis (mild, n = 37; moderate/severe, n = 22), significant between-group differences were found in terms of resistin and CRP levels. Receiver operating curve analysis showed that resistin levels were better for predicting severe cases of acute pancreatitis than CRP or WBC levels on day 3 (area under the curve [AUC], 0.88 versus 0.81 and 0.63, respectively). Resistin levels on day 3 were better than CRP levels for predicting necrosis development (AUC, 0.70 versus 0.69, respectively). Resistin may represent a new, effective indicator to predict the severity of acute pancreatitis and presence of necrosis in patients with acute pancreatitis. © The Author(s) 2016.

    Energy expenditure (EE) was measured, during 3 consecutive days, in six patients suffering from acute pancreatitis. Measurements were achieved postoperatively, under mechanical ventilation, using a mass spectrometer system. EE represented 1.49 times (range: 1.08-1.78) the predicted resting energy expenditure (PREE) according to the reevaluated Harris-Benedict equation. There was a weak positive correlation between EE and core temperature and a negative correlation between EE and nitrogen balance. EE/PREE was not different between septic and nonseptic patients (1.58 +/- 0.06 vs. 1.39 +/- 0.07). The calculations of nutrient oxidation rate indicated a high protein catabolic rate, a neoglucogenesis, and a lipolysis.

    2007-05-01

    Full Text Available Hypercalcemia complicating malignancy is a rare complication in pediatric age group. In this article, we present a case with acute lymphoblastic leukemia presenting as severe hypercalcemia. A 10 years old girl presented with an acute onset of fever, nausea, vomiting, loss of weight, costovertebral pain and frequency. She was admitted with a presumptive diagnosis of acute pyelonephritis. Her examination showed mild hepatosplenomegaly. In laboratory studies she had sever hypercalcemia. Despite the absence of circulating blast, bone marrow aspiration was diagnostic of acute lymphoblastic leukemia. The hypercalcemia was initially treated with intravenous hydration and furosemide but the serum calcium levels normalized only after the beginning of specific chemotherapy. Hypercalcemia represents an emergency in children, and acute leukemia must be considered in differential diagnosis even when there are no circulating blasts.

    To explore the effect of nonalcoholic fatty liver as a hepatic manifestation of metabolic syndrome on the severity of acute pancreatitis. We hypothesized that patients with nonalcoholic fatty liver would have a more severe form of acute pancreatitis. We retrospectively analyzed 822 patients hospitalized with acute pancreatitis. We diagnosed acute pancreatitis and determined its severity according the revised Atlanta classification criteria from 2012. We assessed nonalcoholic fatty liver with computed tomography. There were 198 (24.1%) patients out of 822 analyzed who had nonalcoholic fatty liver. Patients with nonalcoholic fatty liver had statistically higher incidence of moderately severe (35.4% vs. 14.6%; p=0.02) and severe acute pancreatitis (20.7% vs. 9.6%; pacute pancreatitis and nonalcoholic fatty liver (OR 2.13, 95%CI 1.236-3.689). Compared to patients without nonalcoholic fatty liver, patients with nonalcoholic fatty liver had a higher death rate, however not statistically significant (5.6% vs. 4.3%; p=NS). Presence of nonalcoholic fatty liver at admission can indicate a higher risk for developing more severe forms of acute pancreatitis and could be used as an additional prognostic tool.

    Contrast-induced acute kidney injury (CI-AKI) accounts for approximately 10% of all causes of hospital-acquired renal failure, causes a prolonged in-hospital stay, and represents a powerful predictor of poor early and late outcome. Here, we highlight endpoints used to assess major strategies to prevent CI-AKI. A general consensus exists on the beneficial prophylactic effect of hydration. This seems to act by increasing urine flow rate and, thereby, by limiting the time of contact between the contrast media and the epithelial tubular cells. On the contrary, both observational trials and randomized studies are often controversial in their conclusions on the efficacy of several drugs tested to prevent CI-AKI. Compounds evaluated include diuretics (furosemide), antioxidants (i.e., N-acetylcysteine and statins), and vasodilators (i.e., calcium antagonists, dopamine, and fenoldopam). Due to the negative and/or controversial clinical results, none of these drugs has been currently recommended to prevent CI-AKI. More reliable markers of acute kidney injury and new prophylactic strategies are warranted to prevent the incidence of CI-AKI.

    To determine the diagnostic accuracy of modified CT severity index in assessing the severe acute pancreatitis keeping APACHE II as gold standard. Cross-sectional (validation) study. Department of Radiology, Allied Hospital, Faisalabad, from February to August 2014. A total of 120 patients of either gender aged 20-60 years with epigastric pain radiating to back and having sonographic findings (decreased or heterogeneous pancreatic echogenicity, pancreatic enlargement, peripancreatic fluid collection), supportive of acute pancreatitis were taken. CT with intravenous contrast was performed on 128-slice scanner within 24 hours of presentation. Slice thickness was 3 mm in region of pancreas. Modified CT severity index was calculated. Score above 5 was graded as severe pancreatitis. APACHE II score of >11 considered as gold standard was also calculated within 24 hours of admission. Mean age of the patients was 39.03 ±8.71 years. Most of the patients were females 73 (60.8%). Out of 120 patients, 43 (35.83%) patients had severe acute pancreatitis. Sensitivity, specificity, positive predictive value and negative predictive value of modified CT severity index in assessing the severe acute pancreatitis were 100%, 87%, 81.13% and 100%, respectively. The diagnostic accuracy was yielded as 91.67% considered APACHE II as gold standard. Modified CT severity index had high diagnostic accuracy in assessment of severe acute pancreatitis and can be used reliably in early prediction of complications of severe acute pancreatitis.

    Haemorrhage can be a lethal complication of severe acute pancreatitis. Management includes identification and control of the source of bleeding and supportive therapy such as blood transfusion. Individuals who refuse transfusion on the grounds of religious belief can provide a further major challenge. The management in these individuals can be focused from the outset with a strategy that aims to avert anaemia and transfusion. This article reports a case of severe acute pancreatitis in a woman of the Jehovah's Witness faith. The episode was complicated by infected pancreatic necrosis requiring surgical intervention. Careful strategic planning is critical to the management of severe acute pancreatitis in patients of the Jehovah's Witness faith. In this case, acute pancreatitis complicated by infected necrosis was successfully managed by the use of preoperative erythropoietin, venesection using paediatric blood vials, meticulous intraoperative attention to haemostasis and the use of adjunctive intraoperative techniques such as argon diathermy.

    Full Text Available Abstract Severe acute exacerbation or liver failure induced by standard interferon-α(IFN-α therapy had been reported to occur in few patients with chronic hepatitis B. However, no report showed that pegylated interferon-α therapy was able to induce severe acute exacerbation of chronic hepatitis B. Here, we describe three patients with severe acute exacerbation of chronic hepatitis B during pegylated interferon-α2a (Pegasys treatment. One patient progressed into acute-on-chronic liver failure (ACLF at the second week of Pegasys treatment. Two patients progressed into acute-on-chronic pre-liver failure (pre-ACLF at the second and eighth week of Pegasys treatment, respectively. Three patients recovered after early combined intervention with corticosteroid and lamivudine. Our data indicated that there was a risk of severe acute exacerbation among patients with chronic hepatitis B during receiving Pegasys treatment. Importantly, early combined intervention with corticosteroid and lamivudine should be introduced to prevent the disease progression and improve their prognosis once severe acute exacerbation was diagnosed.

    The role of liver transplantation (LT) in acute liver failure (ALF) complicated by severe acute pancreatitis is still unclear. We here report a case of deceased-donor LT for idiopathic ALF accompanied by severe acute pancreatitis. A 58-year-old man with no history of liver disease presented with idiopathic ALF and acute pancreatitis. After careful consideration, he received a liver from a deceased donor. Following surgery, the patient's liver function rapidly reverted to normal level and the acute pancreatitis simultaneously subsided. The patient later developed a pancreatic pseudocyst, which was treated successfully with combination interventional radiology. LT can be considered for ALF associated with severe acute pancreatitis if there is no clinical evidence of an absolute contraindication for organ transplantation, such as systemic or local infection. Moreover, we recommend a close follow-up by ultrasonography to allow early detection and treatment of pancreatic pseudocysts following surgery. 2016 BMJ Publishing Group Ltd.

    2014-01-01

    It is well known that iodinated radiographic contrast media may cause kidney dysfunction, particularly in patients with preexisting renal impairment associated with diabetes. This dysfunction, when severe, will cause acute renal failure (ARF). We may define contrast-induced Acute Kidney Injury (AKI) as ARF occurring within 24–72 hrs after the intravascular injection of iodinated radiographic contrast media that cannot be attributed to other causes. The mechanisms underlying contrast media nephrotoxicity have not been fully elucidated and may be due to several factors, including renal ischaemia, particularly in the renal medulla, the formation of reactive oxygen species (ROS), reduction of nitric oxide (NO) production, and tubular epithelial and vascular endothelial injury. However, contrast-induced AKI can be prevented, but in order to do so, we need to know the risk factors. We have reviewed the risk factors for contrast-induced AKI and measures for its prevention, providing a long list of references enabling readers to deeply evaluate them both. PMID:25197639

    Acute pancreatitis is one of the most common diseases of the gastrointestinal tract and is usually caused by gallstones; its occurrence in pregnancy is rare. Cholecystectomy for biliary pancreatitis during pregnancy is unavoidable, but its timing is controversial. We herein present the case of a patient who underwent termination of pregnancy due to deteriorated acute severe pancreatitis during the 27th week of gestation. Cholecystectomy was performed because of the relapse of acute biliary pancreatitis 10 days after being discharged. The interval from pancreatitis to cholecystectomy varies with its severity; in mild pancreatitis the interval may be one week, but in severe cases it maybe up to three weeks. Because pancreatitis may relapse during this interval, as occurred in the present case, a better solution for the timing of cholecystectomy must be sought.

    To assess and compare management preferences of physicians for moderate and severe acute asthma based on case scenarios and to determine the factors influencing their decisions. A questionnaire based on the Global Initiative on Asthma (GINA) guideline and comprising eight questions on management of acute asthma was delivered to participants of two national pediatric congresses. Management of moderate and severe acute asthma cases was evaluated by two clinical case scenarios for estimation of acute attack severity, initial treatment, treatment after 1h, and discharge recommendations. A uniform answer box comprising the possible choices was provided just below the questions, and respondents were requested to tick the answers they thought was appropriate. Four-hundred and eighteen questionnaires were analyzed. All questions regarding moderate and severe acute asthma case scenarios were answered accurately by 15.8% and 17.0% of physicians, respectively. The initial treatment of moderate and severe cases was known by 100.0% and 78.2% of physicians, respectively. Knowledge of the appropriate plan for treatment after 1h was low both for moderate (45.0%) and severe attacks (35.4%). Discharge recommendations were adequate in 32.5% and 70.8% of physicians for moderate and severe attacks, respectively. Multiple logistic regression analysis revealed that working at a hospital with a continuing medical education program was the only significant predictor of a correct response to all questions regarding severe attacks (p = .04; 95%CI, 1.02-3.21). No predictors were found for information on moderate attacks. Pediatricians have difficulty in planning treatment after 1 hour both for moderate and severe asthma attacks. Postgraduate education programs that target physicians in hospitals without continuing medical education facilities may improve guideline adherence.

  18. Preventing drug resistance in severe influenza

    Dobrovolny, Hana; Deecke, Lucas

    2015-03-01

    Severe, long-lasting influenza infections are often caused by new strains of influenza. The long duration of these infections leads to an increased opportunity for the emergence of drug resistant mutants. This is particularly problematic for new strains of influenza since there is often no vaccine, so drug treatment is the first line of defense. One strategy for trying to minimize drug resistance is to apply periodic treatment. During treatment the wild-type virus decreases, but resistant virus might increase; when there is no treatment, wild-type virus will hopefully out-compete the resistant virus, driving down the number of resistant virus. We combine a mathematical model of severe influenza with a model of drug resistance to study emergence of drug resistance during a long-lasting infection. We apply periodic treatment with two types of antivirals: neuraminidase inhibitors, which block release of virions; and adamantanes, which block replication of virions. We compare the efficacy of the two drugs in reducing emergence of drug resistant mutants and examine the effect of treatment frequency on the emergence of drug resistant mutants.

    Full Text Available Germ-cell tumors are a high-proliferative type of cancer that may evolve to significant bulky disease. Tumor lysis syndrome is rarely reported in this setting. The reports of three patients with germ-cell tumors who developed severe acute tumor lysis syndrome following the start of their anticancer therapy are presented. All patients developed renal dysfunction and multiorgan failure. Patients with extensive germ-cell tumors should be kept on close clinical and laboratory monitoring. Physicians should be aware of this uncommon but severe complication and consider early admission to the intensive care unit for the institution of measures to prevent acute renal failure.

    Acute pancreatitis is a common, costly, potentially lethal, and poorly understood disease, mostly caused by gallstones. In the past decade the incidence of acute pancreatitis in the Netherlands increased by 50% to over 3400 admissions in 2006, most likely due to an increase of gallstone disease.

    Biodanza is a useful therapy for the fibromyalgia management; however, there is no evidence of its effectiveness on acute pain. The objectives of the present study were: to determine the changes of a 3-month Biodanza program on acute pain severity (before vs. after session) and cumulative pain severity in women with fibromyalgia; and to check the associations of acute pain severity reduction with presession pain severity, body fat percentage, and satisfaction with the session. This was a 3-month low-moderate intensity (rate of perceived exertion around 12, based on a 6-20 point scale) Biodanza intervention study (1 session/week). Twenty-seven women with fibromyalgia (54.2 ± 6.2 years) participated. Pain severity was assessed before and after each single session with a visual analog scale. There were immediate changes in all sessions (p = .001-.028), except in the first, second, and fourth sessions. An overall 16% decrease of acute pain severity before and after each session was noted (mean presession pain vs. postsession pain, 5.8 ± 2.1 vs. 4.9 ± 2.4; respectively). There was an independent association of pain severity reduction (presession-postsession) with presession pain severity (unstandardized coefficient B = .21 ± .05; standardized coefficient β = .25; p pain severity (p pain severity (p = .007; 95% CI = .02, .12) along the 3-month intervention. No significant cumulative effect in presession pain severity was identified (p > .05). In conclusion, Biodanza is an alternative therapy that reduced acute pain severity in women with fibromyalgia. The intervention also yielded cumulative pain severity reduction, which were higher in those women with fibromyalgia presenting higher presession pain severity and lower body fat percentage. The satisfaction with the session was also a key factor positively associated with pain reduction. Copyright © 2017 American Society for Pain Management Nursing. Published by Elsevier Inc.

    Full Text Available Introduction. Caffeine is indicated in the treatment of migraine headaches, as well as neonatal apnea and bradycardia syndrome. In mild poisoning, the most prevalent symptoms are nausea, vomiting, diarrhea, tremor, anxiety and headache. In more severe cases, symptoms consist of heart rythym abnormalities, myocardial infarction and seizures. Due to its common lipolytic effect, caffeine is used in mesotherapy, usually in combination with drugs of similar effect. We presented a patient with acute iatrogenic caffeine poisoning. Case report. A 51-year-old woman, with preexisting hypertension and hypertensive cardiomyopathy was subjected to cosmetic treatment in order to remove fat by intradermal caffeine injections. During the treatment the patient felt sickness, an urge to vomit, and a pronounced deterioration of general condition. Upon examination, the patient exhibited somnolence, hypotension and nonsustained ventricular tachycardia, which was sufficient enough evidence for further hospitalization. On admission to the intensive care unit the patient was anxious with increased heart rate, normotensive, with cold, damp skin, and visible traces of injection sites with surrounding hematomas on the anterior abdominal wall. Paroxysmal supraventricular tachycardia (PSVT on electrocardiographic monitoring was found. The laboratory analysis determined a lowered potassium level of 2.1 mmol/L (normal range 3,5 - 5.2 mmol/L, and a toxicological analysis (liquid chromatography with ultraviolet detection proved a toxic concentration of caffeine in plasma - 85.03 mg/L (toxic concentration over 25 mg/L. On application of intensive therapy, antiarrhythmics, and substitution of potassium, as well as both symptomatic and supportive therapy, there was a significant recovery. The patient was discharged without any sequele within four days. Conclusion. A presented rare iatrogenic acute caffeine poisoning occured due to massive absorption of caffeine from the

  14. Microbiota is immature in moderate and severe acute malnutrition

    Full text: Globally 19 million under-five children suffer from severe acute malnutrition (SAM) while 51.5 million children have moderate acute malnutrition (MAM). These two conditions, together known as acute malnutrition, are responsible for 14.6% of all under-five deaths. Case fatality rate can be reduced with treatment of SAM, which however, is not readily available everywhere. Even with effective treatment, recovery can be slow and relapse not uncommon. Lack of nutrients is one of the causes of acute malnutrition but other factors including infections, inter- and intra-generational factors are also believed to play important roles in the etiology. The gut microbiota is another factor; however its relationship with nutritional interventions and therapeutic response is poorly understood. We studied the gut microbiota of children suffering from severe and moderate acute malnutrition in Bangladesh. Children with SAM were studied during the acute phase, nutritional rehabilitation and follow up in icddr,b Hospital, Dhaka. During the nutritional rehabilitation phase, the children were randomized to either RUTF or a combination of local diets (khichuri and halwa). Children with MAM were randomly selected from a birth cohort in a slum settlement and so were healthy controls. Gut microbiota were identified using 16S rRNA datasets generated from monthly fecal samples obtained from the healthy control children. ‘Relative microbiota maturity index’ and ‘microbiota-for-age Z-score’ were computed from a model developed from the age-discriminatory bacterial species identified in the healthy and acutely malnourished children. The index and the Z-score compare maturation of an acutely malnourished child’s fecal microbiota relative to healthy children of similar chronological age. Our results indicate that SAM is associated with relative immaturity of the gut microbiota. Moreover, treatment with either RUTF or the local diets is associated with incomplete recovery of

    Salicylate poisoning remains a significant public health threat with more than 20,000 exposures reported annually in the United States. We aimed to establish early predictors of severe in-hospital outcomes in Emergency Department patients presenting with acute salicylate poisoning. This was a secondary data analysis of adult salicylate overdoses from a prospective cohort study of acute drug overdoses at two urban university teaching hospitals from 2009 to 2013. Patients were included based on confirmed salicylate ingestion and enrolled consecutively. Demographics, clinical parameters, treatment and disposition were collected from the medical record. Severe outcome was defined as a composite occurrence of acidemia (pH salicylate concentration 28.1 mg/dL (SD 26.6), and 20.8% classified as severe outcome. Univariate analysis indicated that age, respiratory rate, lactate, coma, and the presence of co-ingestions were significantly associated with severe outcome, while initial salicylate concentration alone had no association. However, when adjusted for salicylate concentration, only age (OR 1.13; 95% CI 1.02-1.26) and respiratory rate (OR 1.29; 95% CI 1.02-1.63) were independent predictors. Additionally, lactate showed excellent test characteristics to predict severe outcome, with an optimal cutpoint of 2.25 mmol/L (78% sensitivity, 67% specificity). In adult Emergency Department patients with acute salicylate poisoning, independent predictors of severe outcome were older age and increased respiratory rate, as well as initial serum lactate, while initial salicylate concentration alone was not predictive.

    Acute diverticulitis of the colon represents a significant burden for national health systems, in terms of direct and indirect costs. Past guidelines claimed that recurrent episodes (two or more) of diverticulitis need surgery, but revised guidelines recommend an individualized approach to patients after an attack of acute diverticulitis. For these reasons, conservative treatment has become the preferred choice after an episode of diverticulitis. Thus, significant efforts are now being focuse...

    Acute appendicitis is the most common indication for pediatric abdominal emergency surgery. Determination of the severity of appendicitis on clinical grounds is challenging. Complicated appendicitis presenting with perforation, abscess or diffuse peritonitis is not uncommon. The question remains why and when acute appendicitis progresses to perforation. The aim of this study was to assess the impact of water permeability on the severity of appendicitis. We show that AQP1 expression and water permeability in appendicitis correlate with the stage of inflammation and systemic infection parameters, leading eventually to perforation of the appendix. AQP1 is also expressed within the ganglia of the enteric nervous system and ganglia count increases with inflammation. Severity of appendicitis can be correlated with water permeability measured by AQP1 protein expression and increase of ganglia count in a progressive manner. This introduces the question if regulation of water permeability can present novel curative or ameliorating therapeutic options.

    2014-02-01

    Extracorporeal life support (ECLS) is an artificial means of maintaining adequate oxygenation and carbon dioxide elimination to enable injured lungs to recover from underlying disease. Technological advances have made ECLS devices smaller, less invasive, and easier to use. ECLS might, therefore, represent an important step towards improved management and outcomes of patients with acute respiratory distress syndrome. Nevertheless, rigorous evidence of the ability of ECLS to improve short-term and long-term outcomes is needed before it can be widely implemented. Moreover, how to select patients and the timing and indications for ECLS in severe acute respiratory distress syndrome remain unclear. We describe the physiological principles, the putative risks and benefits, and the clinical evidence supporting the use of ECLS in patients with acute respiratory distress syndrome. Additionally, we discuss controversies and future directions, such as novel technologies and indications, mechanical ventilation of the native lung during ECLS, and ethics considerations.

    The aim of this study was to develop a new international classification of acute pancreatitis severity on the basis of a sound conceptual framework, comprehensive review of published evidence, and worldwide consultation. The Atlanta definitions of acute pancreatitis severity are ingrained in the lexicon of pancreatologists but suboptimal because these definitions are based on empiric descriptions of occurrences that are merely associated with severity. A personal invitation to contribute to the development of a new international classification of acute pancreatitis severity was sent to all surgeons, gastroenterologists, internists, intensive medicine specialists, and radiologists who are currently active in clinical research on acute pancreatitis. The invitation was not limited to members of certain associations or residents of certain countries. A global Web-based survey was conducted and a dedicated international symposium was organised to bring contributors from different disciplines together and discuss the concept and definitions. The new international classification is based on the actual local and systemic determinants of severity, rather than descriptions of events that are correlated with severity. The local determinant relates to whether there is (peri)pancreatic necrosis or not, and if present, whether it is sterile or infected. The systemic determinant relates to whether there is organ failure or not, and if present, whether it is transient or persistent. The presence of one determinant can modify the effect of another such that the presence of both infected (peri)pancreatic necrosis and persistent organ failure have a greater effect on severity than either determinant alone. The derivation of a classification based on the above principles results in 4 categories of severity - mild, moderate, severe, and critical. This classification is the result of a consultative process amongst pancreatologists from 49 countries spanning North America, South America

    Full Text Available Severe acute chromium poisoning related to dermal involvement has rarely been reported in the literature. We report a case of acute severe chromium poisoning through skin exposure as a result of a chemical burn of 15% of the body surface area and multiple organ failure after short-term exposure. Medical interventions, including mechanical ventilation, continuous venovenous hemofiltration, and plasmapheresis were performed. In addition, a chelating agent, dimercapto-propane sulfonic acid, was infused intravenously, combined with intravenous N-acetylcysteine and ascorbic acid as adjuvant therapy. The patient was discharged on day 33 without long-term sequelae. The consequence of transdermal exposure of hexavalent chromium should not be overlooked.

    High-quality evidence supporting a community-based treatment protocol for children with severe acute malnutrition, including routine antibiotic use at admission to a nutritional treatment program, remains limited. In view of the costs and consequences of emerging resistance associated with routine antibiotic use, more evidence is required to support this practice. In a double-blind, placebo-controlled trial in Niger, we randomly assigned children who were 6 to 59 months of age and had uncomplicated severe acute malnutrition to receive amoxicillin or placebo for 7 days. The primary outcome was nutritional recovery at or before week 8. A total of 2412 children underwent randomization, and 2399 children were included in the analysis. Nutritional recovery occurred in 65.9% of children in the amoxicillin group (790 of 1199) and in 62.7% of children in the placebo group (752 of 1200). There was no significant difference in the likelihood of nutritional recovery (risk ratio for amoxicillin vs. placebo, 1.05; 95% confidence interval [CI], 0.99 to 1.12; P=0.10). In secondary analyses, amoxicillin decreased the risk of transfer to inpatient care by 14% (26.4% in the amoxicillin group vs. 30.7% in the placebo group; risk ratio, 0.86; 95% CI, 0.76 to 0.98; P=0.02). We found no benefit of routine antibiotic use with respect to nutritional recovery from uncomplicated severe acute malnutrition in Niger. In regions with adequate infrastructure for surveillance and management of complications, health care facilities could consider eliminating the routine use of antibiotics in protocols for the treatment of uncomplicated severe acute malnutrition.

Moreover, conventional aggressive management might be futile in acute severe asthma requiring intubation and invasive ventilation. The aim of this review is to detail evidence on the use of ketamine in childhood asthma exacerbations. A search of the MEDLINE, EMBASE, and Cochrane databases was performed, using different combinations of the following terms: ketamine, asthma, use, exacerbation, and childhood. In addition, we searched the references of the identified articles for additional articles. We then reviewed titles and included studies that were relevant to the topic of interest. Finally, the search was limited to studies published in English and Spanish from 1918 to June 2015. Due to the scarcity in the literature, we included all published articles. The literature reports conflicting results of ketamine use for acute severe asthma in children. Taking into consideration the relatively good safety profile of the drug, ketamine might be a reasonable option in the management of acute severe asthma in children who fail to respond to standard therapy. Furthermore, pediatricians and pediatric emergency clinicians administering ketamine should be knowledgeable about the unique actions of this drug and its potential side effects.

    Raynaud's phenomenon is an exaggerated vasospastic response to cold or emotional stress which not only may cause the patient severe pain but also critical ischaemia and necrosis of the digits. We report the case of a 69-year-old woman who presented with rest pain, impending ulceration and necrosis of finger tips due to an episode of left-sided Raynaud's phenomenon. Intravenous prostacyclin was administered successfully as a bridge to endoscopic thoracic sympathectomy. Vascular surgery units are ideally positioned for the acute management of severe Raynaud's phenomenon to provide continuity of care to patients with profound digital ischaemia and impending tissue loss.

    Full Text Available Early intensive care for severe acute pancreatitis is essential for improving SAP mortality rates. However, intensive therapies for SAP are often delayed because there is no ideal way to accurately evaluate severity in the early stages. Currently, perfusion CT has been shown useful to predict prognosis of SAP in the early stage. In this presented paper, we would like to review the clinical usefulness and limitations of perfusion CT for evaluation of local and systemic complications in early stage of SAP.

    Scorpionism is a public health problem in various regions of the world, being Mexico the country with the highest number of cases. Clinical manifestations range from local symptoms to severe disease with an impact on cardiovascular, respiratory and neurological level, and even death. There are no reports of acute flaccid paralysis as a manifestation of the clinical picture of the scorpion sting of the Centruroides gender, Family Buthidae, highly toxic, causes high rates of morbidity and mortality in our region. We documented a case of scorpionism, caused by a scorpion gender Buthidae, Centruroides family, which caused acute flaccid paralysis, after resolution of other severe manifestations. There is only one case report of scorpionism that produces acute flaccid paralysis in the literature, but it is related to the Parabuthus scorpion, endemic of South Africa. The knowledge of this complication, new for our region, will maximize efforts to diagnose and appropriately manage this symptoms, with the adequate application of the specific fabotherapy and advanced life support for proper survival in the patients with compromise of vital functions and imminent risk of death mainly by respiratory failure.

    Full Text Available Introduction: Postoperative pain as an important medical concern is usually treated by opioids which also are of various inevitable side effects. The aim of this study was to assess the efficacy of multimodal preincisional premedication on preventing post-cholecystectomy acute pain. Methods: In a randomized clinical trial, sixty patients undergoing open cholecystectomy were randomized into two groups. Before anesthesia induction, Diclofenac suppository (100 mg and oral Clonidine (0.2 mg were administered in the first group. Immediately before operation, patients received Ketamine (1 mg/kg IV while the control group received placebo. The site of incision was infiltrated by the surgeon with 20 mL Bupivacaine 0.25% in both groups. Anesthesia induction and maintenance were similar in both groups. The severity of pain was recorded 2, 4, 6, 12, 24 and 48 hours after operation according to Visual Analogue Scale. Results: The severity of pain at two defined stages (6 and 12 hours later was significantly less in the intervention group than the control group (P<0.005. The average pain severity score was less than the control group (P<0.005. Conclusion: In our study, the administration of Clonidine, Diclofenac and Ketamine and bupivacaine infiltration to the site of incision, altogether was associated with a significant decrease in pain score and opioid requirement after cholecystectomy in comparison to bupivacaine infiltration to the site of incision.

    This chart review was undertaken to assess efficacy and safety of hydroxocobalamin for acute cyanide poisoning. Hospital records of the Fernand Widal and Lariboisière Hospitals were reviewed for intensive care unit admissions with cyanide poisoning for which hydroxocobalamin was used as first-line treatment from 1988 to 2003. Smoke inhalation cases were excluded. Hydroxocobalamin (5-20 g) was administered to 14 consecutive patients beginning a median 2.1 hours after cyanide ingestion or inhalation. Ten patients (71%) survived and were discharged. Of the 11 patients with blood cyanide exceeding the typically lethal threshold of 100 micromol/L, 7 survived. The most common hydroxocobalamin-attributed adverse events were chromaturia and pink skin discoloration. Severe cyanide poisoning of the nature observed in most patients in this study is frequently fatal. That 71% of patients survived after treatment with hydroxocobalamin suggests that hydroxocobalamin as first-line antidotal therapy is effective and safe in acute cyanide poisoning.

    2013-01-01

    Full Text Available The paper considers the problems of diagnosis of severe thallium salt poisoning in early-stage intoxication, which are associated with the fact that alopecia, a clinical typical symptom of thallium toxicity, appears in the period exceeding two weeks. At the same time, in severe poisoning a fatal outcome occurs much more early and the first signs of intoxication are highly diversified and nonspecific. The clinical manifestations with no specificity at the early period of intoxication in conjunction with the absence of certain history data result in late (sometimes postmortem diagnosis in the vast majority of cases, particularly, in criminal cases. This comprises a danger of acute severe thallium poisoning since unrecognized intoxication leads to incorrect treatment and patient death. While making a differential diagnosis, attention should be given to a set of a number of symptoms that arouse suspicion of thallium poisoning, which is an indication for chemical and analytical studies of biological environments in these patients. This paper summarizes the available data on ethyology, pathogenesis and cliniu-cal manifestations of severe thallium poisoning and demonstrate own cases of thallium intoxication occurred recently in Yaroslavl and Saint Petersburg. Basic strategy of thallium poisoning treatment is presented and discussed. Key words: acute poisoning, thallium compounds, antidote therapy, diffeferential diagnosis.

    Acute fatty liver of pregnancy is a rare disease that affects women in the third trimester of pregnancy. Although infrequent, the disease can cause maternal mortality. The diagnosis is not always clear until the pregnancy is terminated, and significant complications, such as acute pancreatitis, can occur. Pancreatic involvement typically only occurs in severe cases after the development of hepatic and renal impairment. To date, little knowledge is available regarding how the disease causes pancreatitis. Treatment involves supportive measures and pregnancy interruption. In this report, we describe a case of a previously healthy 26-year-old woman at a gestational age of 27 wk and 6 d who was admitted with severe abdominal pain and vomiting. This case illustrates the clinical and laboratory overlap between acute fatty liver of pregnancy and pancreatitis, highlighting the difficulties in differentiating each disease. Furthermore, the hypothesis for this overlapping is presented, and the therapeutic options are discussed.

    In severe falciparum malaria metabolic acidosis and acute kidney injury (AKI) are independent predictors of a fatal outcome in all age groups. The relationship between plasma acids, urine acids and renal function was investigated in adult patients with acute falciparum malaria. Plasma and urinary acids which previously showed increased concentrations in proportion to disease severity in patients with severe falciparum malaria were quantified. Patients with uncomplicated malaria, sepsis and healthy volunteers served as comparator groups. Multiple regression and multivariate analysis were used to assess the relationship between organic acid concentrations and clinical syndromes, in particular AKI. Patients with severe malaria (n = 90), uncomplicated malaria (n = 94), non-malaria sepsis (n = 19), and healthy volunteers (n = 61) were included. Univariate analysis showed that both plasma and creatinine-adjusted urine concentrations of p-hydroxyphenyllactic acid (pHPLA) were higher in severe malaria patients with AKI (p < 0.001). Multiple regression analysis, including plasma or creatinine-adjusted urinary acids, and PfHRP2 as parasite biomass marker as independent variables, showed that pHPLA was independently associated with plasma creatinine (β = 0.827) and urine creatinine (β = 0.226). Principal component analysis, including four plasma acids and seven urinary acids separated a group of patients with AKI, which was mainly driven by pHPLA concentrations. Both plasma and urine concentrations of pHPLA closely correlate with AKI in patients with severe falciparum malaria. Further studies will need to assess the potential nephrotoxic properties of pHPLA.

    Rhabdomyolysis has multiple etiologies with unclear mechanisms; however, rhabdomyolysis caused by Staphylococcus aureus infection is rare. A case report of severe rhabdomyolysis in a patient who presented with endocarditis caused by methicillin-susceptible S. aureus and review of relevant literature. The patient had a history of cardiac surgery for tetralogy of Fallot. He was admitted to the hospital because of fever and digestive symptoms. Respiratory and hemodynamic status deteriorated rapidly, leading to admission to the intensive care unit (ICU) for mechanical ventilation and vasopressor support. Laboratory tests disclosed severe rhabdomyolysis with a serum concentration of creatine kinase that peaked at 49,068 IU/L; all blood cultures grew methicillin-susceptible S. aureus. Antibiotic therapy was amoxicillin-clavulanic acid, ciprofloxacin, and gentamicin initially and was changed subsequently to oxacillin, clindamycin, and gentamicin. Transesophageal echocardiography showed vegetation on the pulmonary valve, thus confirming the diagnosis of acute endocarditis. Viral testing and computed tomography (CT) scan ruled out any obvious alternative etiology for rhabdomyolysis. Bacterial analysis did not reveal any specificity of the staphylococcal strain. The patient improved with antibiotics and was discharged from the ICU on day 26. He underwent redux surgery for valve replacement on day 53. Staphylococcal endocarditis should be suspected in cases of severe unexplained rhabdomyolysis with acute infectious symptoms.

    Diverticulitis is a common condition with a broad spectrum of disease severity. A scoring system has been proposed for diagnosing diverticulitis, and a number of scoring systems exist for predicting prognosis associated with severe complications of diverticulitis such as peritonitis. However, predicting disease severity has not received as much attention. Therefore, the aim of this review was to identify the factors that are predictive of severe acute diverticulitis. A systematic literature search was performed using Medline, PubMed, EMBASE, and the Cochrane Library to identify papers that evaluated factors predictive of severe diverticulitis. Severe diverticulitis was defined as complicated diverticulitis (associated with haemorrhage, abscess, phlegmon, perforation, purulent/faecal peritonitis, stricture, fistula, or small-bowel obstruction) or diverticulitis that resulted in prolonged hospital admission, surgical intervention or death. Twenty one articles were included. Studies were categorised into those that identified patient characteristics (n = 12), medications (n = 5), biochemical markers (n = 8) or imaging (n = 3) as predictors. Predictors for severe diverticulitis included first episode of diverticulitis, co-morbidities (Charlson score ≥ 3), non-steroidal anti-inflammatory drug use, steroid use, a high CRP on admission and severe disease on radiological imaging. Age and gender were not associated with disease severity. A number of predictors exist for identifying severe diverticulitis, and CT remains the gold standard for diagnosing complicated disease. Patients who present with identified risk factors for severe disease warrant early imaging, closer in-patient observation and a lower threshold for early surgical intervention. Patients without these factors may be suitable for outpatient-based treatment. Copyright © 2016 IJS Publishing Group Limited. Published by Elsevier Ltd. All rights reserved.

    Infected pancreatic necrosis (IPN) and multiple organ dysfunction syndrome (MODS) are major complications of acute pancreatitis which determine disease severity and outcome. The aim of this study is to investigate the value of admission heart rate variability as a marker of IPN or MODS in severe acute pancreatitis (SAP) patients. Forty-one SAP patients within 72 h of symptoms onset were included in this prospective observational study. General demographics, laboratory data and the acute physiology and chronic health evaluation (APACHE) II scores were recorded at admission. 5-minute ECG signals were obtained at the same time for heart rate variability analyses to assess SAP severity. The baseline heart rate variability measurements, levels of low frequency/high frequency (LF/HF) were significantly lower whereas high frequency norm (nHF) levels were significantly higher in patients who present with IPN and MODS or died (P procalcitonin. nHF and LF/HF were better than APACHE II in predicting IPN and LF/HF showed superiority over APACHE II in the prediction of MODS. Admission heart rate variability is a good marker of IPN and MODS in SAP patients.

    Severe acute malnutrition (SAM) is an important risk factor for illness and death globally, contributing to more than half of deaths in children worldwide. We hypothesized that SAM is positively correlated to poverty, low educational attainment, major crime and higher mean soil concentrations of lead, cadmium and arsenic. We reviewed admission records of infants admitted with a diagnosis of SAM over 14 years (2000-2013) in Jamaica. Poverty index, educational attainment, major crime and environmental heavy metal exposure were represented in a Geographic Information System (GIS). Cases of SAM were grouped by community and the number of cases per community/year correlated to socioeconomic variables and geochemistry data for the relevant year. 375 cases of SAM were mapped across 204 urban and rural communities in Jamaica. The mean age at admission was 9 months (range 1-45 months) and 57% were male. SAM had a positive correlation with major crime (r = 0.53; P crimes reported, the rate of occurrence of SAM cases increased by 1.01% [Incidence rate ratio (IRR) = 1.01 (95% CI = 1.006-1.014); P Pcrime has an independent positive association with severe acute malnutrition in Jamaican infants. This could suggest that SAM and major crime might have similar sociological origins or that criminality at the community level may be indicative of reduced income opportunities with the attendant increase in poor nutrition in the home.

    Acute renal failure (ARF) is a rare but potentially fatal complication of diabetic ketoacidosis (DKA). Early recognition and aggressive treatment of ARF during DKA may im-prove the prognosis of these patients. We present a case report of a 12 year old female admitted to the hospital with severe DKA as the 1s t manifestation of her diabetes mellitus. She presented with severe metabolic acidosis, hypophosphatemia, and oliguric ARF. In addition, rhabdomyolysis was noted during the course of DKA which probably contributed to the ARF. Management of DKA and renal replacement therapy resulted in quick recovery of renal function. We suggest that early initiation of renal replacement therapy for patients with DKA developing ARF may improve the potentially poor outcome of patients with ARF associated with DKA.

  18. Gut Bacteria Missing in Severe Acute Malnutrition, Can We Identify Potential Probiotics by Culturomics?

    Full Text Available Severe acute malnutrition is the world-leading cause of children under-five's death. Recent metagenomics studies have established a link between gut microbiota and severe acute malnutrition, describing an immaturity with a striking depletion in oxygen-sensitive prokaryotes. Amoxicillin and therapeutic diet cure most of the children with severe acute malnutrition but an irreversible disruption of the gut microbiota is suspected in the refractory and most severe cases. In these cases, therapeutic diet may be unable to reverse the microbiota alteration leading to persistent impaired development or death. In addition, as enteric sepsis is a major cause of death in this context, identification of missing gut microbes to be tested as probiotics (live bacteria that confer a benefit to the host to restore rapidly the healthy gut microbiota and prevent the gut pathogenic invasion is of foremost importance. In this study, stool samples of malnourished patients with kwashiorkor and healthy children were collected from Niger and Senegal and analyzed by culturomics and metagenomics. We found a globally decreased diversity, a decrease in the hitherto unknown diversity (new species isolation, a depletion in oxygen-sensitive prokaryotes including Methanobrevibacter smithii and an enrichment in potentially pathogenic Proteobacteria, Fusobacteria and Streptococcus gallolyticus. A complex of 12 species identified only in healthy children using culturomics and metagenomics were identified as probiotics candidates, providing a possible, defined, reproducible, safe, and convenient alternative to fecal transplantation to restore a healthy gut microbiota in malnourished children. Microbiotherapy based on selected strains has the potential to improve the current treatment of severe acute malnutrition and prevent relapse and death by reestablishing a healthy gut microbiota.

    To analyze severe acute occupational poisoning accidents reported in China between 1989 and 2003, and to study the characteristics of severe acute occupational poisoning accidents and provide scientific evidences for prevention and control strategies. The data from the national occupational poisoning case reporting system were analyzed with descriptive methods. (1) There were 506 acute severe occupational poisoning accidents for 15 years with 4 657 workers poisoned. The total poisoning rate was 54.8%, and the total mortality was 16.5%. The average poisoning age was (31.9 +/- 9.8) years old and the average death age was (33.7 +/- 10.3) years old. The poisoning accidents occurred more in men than in women. (2) There were more than 112 chemicals which caused these poisoning accidents. Most of the accidents caused by hydrogen sulfide, carbon monoxide, benzene and homologs, metal and metalloid and carbon dioxide, and the types of chemicals varied in different types of industries. (3) The accidents mainly occurred in chemical industry, manufacture, water disposal industry, mining and construction industry, and the risk was higher in some jobs than others, such as cleanout, machine maintenance and repair, production, mine and digging. The accidents occurred more frequently from April to August each year. (1) The control over the severe acute occupational poisoning is urgent. (2) The trend of the characteristics of severe acute occupational poisoning accidents is centralized in the high risk industries, poisons and jobs. (3) The characteristics of the accidents varied in different types of industries. (4) It is the key point to strengthen the supervision on poisoning.

    Children presenting to emergency departments (ED) with acute severe asthma unresponsive to initial medical therapy may require endotracheal intubation and mechanical ventilation. There is little data on complications during the acute management of children with life-threatening asthma, particularly at hospitals where specialist paediatric staff are lacking. It was hypothesised that a better understanding of complications, particularly associated with intubation and mechanical ventilation, would improve acute management in ED, aid quality improvement initiatives at district general hospitals (DGH) and form the basis for educational interventions from regional paediatric critical care units. A retrospective case note review was performed for all children referred to a regional intensive care retrieval service with status asthmaticus over a 2-year period. Initial treatment, patient-related factors, indication for endotracheal intubation and the type and occurrence of adverse events during acute management at the DGH were studied. Bivariate and multivariate analyses were undertaken to identify factors associated with the occurrence of complications. 51 (85%) of the 60 children transferred to a paediatric intensive care unit for acute severe asthma required intubation. 36 (70.5%) experienced one or more complications during intubation and in the early phase of mechanical ventilation. The most common complications were hypotension (requiring fluid resuscitation and/or inotropic support) and severe bronchospasm with acute hypercarbia. The indication for intubation significantly affected the chances of a complication occurring during stabilisation. There is considerable morbidity in asthmatic children who are referred to paediatric intensive care. The majority of complications may be anticipated and prevented resulting in improved management at DGH.

    Pulmonary hypertension has been described in horses with severe equine asthma, but its effect on the right ventricle has not been fully elucidated. To evaluate right ventricular structure and function after a 1-week period of pulmonary hypertension secondary to acute exacerbation of severe equine asthma. Prospective study. A clinical episode of severe equine asthma was induced experimentally in six susceptible horses. Examinations in remission and on day 7 of the clinical episode included a physical examination with clinical scoring, echocardiography, arterial blood gas measurements, venous blood sampling for cardiac biomarkers, intracardiac pressure measurements, right ventricular and right atrial myocardial biopsies, airway endoscopy and bronchoalveolar lavage. After 1 month of recovery, physical examination, echocardiography and cardiac biomarker analysis were repeated. Echocardiographic and pressure measurements were compared with those in 10 healthy control horses. All horses developed clinical signs of acute pulmonary obstruction. Right heart pressures increased significantly. Altered right ventricular function could be detected by tissue Doppler and speckle tracking echocardiography. Cardiac troponin concentrations did not increase significantly, but were highly elevated in one horse which exercised in the paddock prior to sampling. Focal neutrophil infiltration was present in two myocardial samples. Even in remission, asthmatic horses showed a thicker right ventricular wall, an increased left ventricular end-systolic eccentricity index at chordal level and decreased right ventricular longitudinal strain compared with controls. The induced clinical episode was rather mild and the number of horses was limited because of the invasive nature of the study. Pulmonary obstruction in asthmatic horses induces pulmonary hypertension with right ventricular structural and functional changes. © 2017 EVJ Ltd.

    The objective was to evaluate the helical CT (HCT) criteria that could indicate severe pulmonary embolism (PE). In a retrospective study, 81 patients (mean age 62 years) with clinical suspicion of PE explored by HCT were studied. The patients were separated into three different groups according to clinical severity and treatment decisions: group SPE included patients with severe PE based on clinical data who were treated by fibrinolysis or embolectomy (n=20); group NSPE included patients with non-severe PE who received heparin (n=30); and group WPE included patients without PE (n=31). For each patient we calculated a vascular obstruction index based on the site of obstruction and the degree of occlusion in the pulmonary artery. We noted the HCT signs, i.e., cardiac and pulmonary artery dimensions, that could indicate acute cor pulmonale. According to multivariate analysis, factors significantly correlated with the severity of PE were: the vascular obstruction index (group SPE: 54%; group NSPE: 24%; p<0.001); the maximum minor axis of the left ventricle (group SPE: 30.2 mm; group NSPE: 40.4 mm; p<0.001); the diameter of the central pulmonary artery (group SPE: 32.4 mm; group NSPE: 28.3 mm; p<0.001); the maximum minor axis of the right ventricle (group SPE: 47.5 mm; group NSPE: 42.7 mm; p=0.029); the right ventricle/left ventricle minor axis ratio (group SPE: 1.63; group NSPE: 1.09; p<0.0001). Our data suggest that hemodynamic severity of PE can be assessed on HCT scans by measuring four main criteria: the vascular obstruction index; the minimum diameter of the left ventricle; the RV:LV ratio; and the diameter of the central pulmonary artery.

    Pancreatic necrosis complicating severe acute pancreatitis is a challenging scenario in contemporary critical care practice; it requires multidisciplinary care in a setting where there is a relatively limited evidence base to support decision making. This commentary provides a concise overview of current management of patients with infected necrosis, focusing on detection, the role of pharmacologic intervention, and the timing and nature of surgical interventions. Fine-needle aspiration of necrosis remains the mainstay for establishment of infection. Pharmacological intervention includes antibiotic therapy as an adjunct to surgical debridement/drainage and, more recently, drotrecogin alfa. Specific concerns remain regarding the suitability of drotrecogin alfa in this setting. Early surgical intervention is unhelpful; surgery is indicated when there is strong evidence for infection of necrotic tissue, with the current trend being toward 'less drastic' surgical interventions.

    Full Text Available We report a case of acute promyelocytic leukemia (APL presenting with severely fibrotic marrow. There are four other reports of similar cases in the literature. Our patient was treated with All-Transretinoic Acid- (ATRA- containing induction chemotherapy, followed by consolidation and maintenance therapy. He achieved a complete morphologic remission with adequate count recovery in a timely fashion, and later a molecular remission was documented. The patient remains in molecular remission and demonstrates normal blood counts now more than 4 years after induction. Since the morphological appearance may not be typical and the bone marrow may not yield an aspirate for cytogenetic analysis, awareness of such entity is important to make a correct diagnosis of this potentially curable disease.

    Systemic inflammatory mediators have an important role in the development of acute pancreatitis. In this study, we investigated the effect of ethyl pyruvate (EP) on pancreas injury in rats with severe acute pancreatitis (SAP) and its possible mechanism. We randomly allocated rats into the following three experimental groups: control and SAP- and EP-treated. Then, we recorded the mortality rate. We harvested tissue specimens for morphological studies, streptavidin-peroxidase immunohistochemistry examination, and Western blot analysis. We tested the levels of pancreatic tissue malondialdehyde and the activity of serum amylase, myeloperoxidase in the pancreas. In addition, we studied nuclear factor-κB (NF-κB) activation, tumor necrosis factor-α levels, and high mobility group box 1 protein expression levels in the pancreas. Treatment with EP after SAP was associated with a reduction in the severity of SAP and pancreas injury. Treatment with EP significantly decreased the expression of tumor necrosis factor-α and high mobility group box 1, and ameliorated malondialdehyde concentration and myeloperoxidase activity in the pancreas in SAP rats. Compared with the SAP group, treatment with EP significantly decreased the number of inflammatory cell infiltration, markedly inhibited pancreatic NF-κB DNA binding, and increased the survival rates. This study demonstrates that preventing the activation of NF-κB by EP ameliorates tissue injury associated with experimental murine acute pancreatitis. This result provides an important insight into the molecular biology of acute pancreatitis. Copyright © 2013 Elsevier Inc. All rights reserved.

    Full Text Available Objective: to study the development of acute respiratory distress syndrome (ARDS in victims with isolated severe brain injury (SBI. Subject and methods. 171 studies were performed in 16 victims with SBI. Their general condition was rated as very critical. The patients were divided into three groups: 1 non-ARDS; 2 Stage 1 ARDS; and 3 Stage 2 ARDS. The indicators of Stages 1 and 2 were assessed in accordance with the classification proposed by V. V. Moroz and A. M. Golubev. Intracranial pressure (ICP, extravascular lung water index, pulmonary vascular permeability, central hemodynamics, oxygenation index, lung anastomosis, the X-ray pattern of the lung and brain (computed tomography, and its function were monitored. Results. The hemispheric cortical level of injury of the brain with function compensation of its stem was predominantly determined in the controls; subcompensation and decompensation were ascertained in the ARDS groups. According to the proposed classification, these patients developed Stages 1 and 2 ARDS. When ARDS developed, there were rises in the level of extravascular lung fluid and pulmonary vascular permeability, a reduction in the oxygenation index (it was 6—12 hours later as compared with them, increases in a lung shunt and ICP; X-ray study revealed bilateral infiltrates in the absence of heart failure in Stage 2 ARDS. The correlation was positive between ICP and extravascular lung water index, and lung vascular permeability index (r>0.4;p<0.05. Conclusion. The studies have indicated that the classification proposed by V. V. Moroz and A. M. Golubev enables an early diagnosis of ARDS. One of its causes is severe brainstem injury that results in increased extravascular fluid in the lung due to its enhanced vascular permeability. The ICP value is a determinant in the diagnosis of secondary brain injuries. Key words: acute respiratory distress syndrome, extravascu-lar lung fluid, pulmonary vascular permeability, brain injury

    Full Text Available Severe acute malnutrition (SAM is an important risk factor for illness and death globally, contributing to more than half of deaths in children worldwide. We hypothesized that SAM is positively correlated to poverty, low educational attainment, major crime and higher mean soil concentrations of lead, cadmium and arsenic.We reviewed admission records of infants admitted with a diagnosis of SAM over 14 years (2000-2013 in Jamaica. Poverty index, educational attainment, major crime and environmental heavy metal exposure were represented in a Geographic Information System (GIS. Cases of SAM were grouped by community and the number of cases per community/year correlated to socioeconomic variables and geochemistry data for the relevant year.375 cases of SAM were mapped across 204 urban and rural communities in Jamaica. The mean age at admission was 9 months (range 1-45 months and 57% were male. SAM had a positive correlation with major crime (r = 0.53; P < 0.001, but not with educational attainment or the poverty index. For every one unit increase in the number of crimes reported, the rate of occurrence of SAM cases increased by 1.01% [Incidence rate ratio (IRR = 1.01 (95% CI = 1.006-1.014; P P<0.001]. The geochemistry data yielded no correlation between levels of heavy metals and the prevalence of malnutrition.Major crime has an independent positive association with severe acute malnutrition in Jamaican infants. This could suggest that SAM and major crime might have similar sociological origins or that criminality at the community level may be indicative of reduced income opportunities with the attendant increase in poor nutrition in the home.

  10. Chronic Hepatitis B with Spontaneous Severe Acute Exacerbation

    2015-11-01

    Full Text Available Chronic hepatitis B virus (HBV infection is a major global health problem with an estimated 400 million HBV carriers worldwide. In the natural history of chronic hepatitis B (CHB, spontaneous acute exacerbation (AE is not uncommon, with a cumulative incidence of 10%–30% every year. While exacerbations can be mild, some patients may develop hepatic decompensation and even die. The underlying pathogenesis is possibly related to the activation of cytotoxic T lymphocyte-mediated immune response against HBV. An upsurge of serum HBV DNA usually precedes the rise of alanine aminotransferase (ALT and bilirubin. Whether antiviral treatment can benefit CHB with severe AE remains controversial, but early nucleos(tide analogues treatment seemed to be associated with an improved outcome. There has been no randomized study that compared the effects of different nucleos(tide analogues (NA in the setting of CHB with severe AE. However, potent NAs with good resistance profiles are recommended. In this review, we summarized current knowledge regarding the natural history, pathogenetic mechanisms, and therapeutic options of CHB with severe AE.

    Full Text Available Aims and Objectives: To study the incidence, demographic profile, and outcome of patients with severe closed head injuries who develop acute arterial infarcts. Materials and Methods: Patients with severe head injury (Glasgow coma score (GCS ≤8 presenting within 8 h of injury in the Department of Neurosurgery over a period of 5 months were enrolled in the study. Patients with penetrating head injury, infarct due to herniation and iatrogenic arterial injuries were excluded from the study. Only arterial infarcts developing within 8 h of injury were included in the study. A computed tomography (CT head was done on all patients within 8 h of injury and repeated if necessary. Arterial infarct was defined as well-demarcated wedge-shaped hypodensity corresponding to an arterial territory on plain CT of the head. Outcome was assessed using Glasgow outcome score (GOS at 1 month post-injury or at death (whichever came earlier. Results: Forty-four patients of severe head injury were included in the study during the above period. Of these, four patients (9.1% had arterial infarcts on the initial CT scan. The male:female ratio was 1:3. The mean age was 54 years (range 3-85 years. Two patients had infarcts in the middle cerebral artery distribution and two in the superior cerebellar artery distribution. Poor outcome (GOS 1-3 was seen in 100% of the patients with arterial infarct compared to 52.5% (n=21 in patients with severe head injury without arterial infarct. Conclusions: A significant percentage of patients with severe head injury have arterial infarcts on admission, which may imply arterial injury. Our study shows that these patients have a poorer prognosis vis-a-vis patient without these findings.

    Severe acute respiratory syndrome (SARS) is an emerging infection that causes a potentially fatal respiratory disease. Although the SARS outbreak lasted less than 1 year, it resulted in significant morbidity and mortality and impacted nursing practices. A literature review was conducted. Only English language research articles in peer-reviewed journals, national organization publications, and book chapters were utilized. Data from 37 relevant articles were extracted, analyzed, and summarized. SARS' clinical description is presented, including its common signs/symptoms, diagnosis, and treatment. Recommended isolation practices for labor and delivery and proper procedures for donning, using, and doffing personal protective equipment are provided. Potential maternal outcomes include spontaneous miscarriage during the first trimester, preterm birth, emergency cesarean section, renal failure, secondary bacterial pneumonia, sepsis, adult respiratory distress syndrome, disseminated intravascular coagulation, surgical site infection, and maternal death. There have been no documented cases of vertical transmission; passive immunity is suspected on the basis of the presence of antibodies in some maternal body fluids. Potential neonatal outcomes include complications related to premature birth, intrauterine growth restriction, respiratory distress syndrome, and severe gastrointestinal manifestations. It is not known if or when SARS will reemerge, but perinatal and neonatal nurses should become familiar with its clinical description and proper infection control procedures to halt potential outbreaks.

    Severe acute pancreatitis (SAP), which is the most serious type of this disorder, is associated with high morbidity and mortality. SAP runs a biphasic course. During the first 1-2 wk, a pro-inflammatory response results in systemic inflammatory response syndrome (SIRS). If the SIRS is severe, it can lead to early multisystem organ failure (MOF). After the first 1-2 wk, a transition from a pro-inflammatory response to an anti-inflammatory response occurs; during this transition, the patient is at risk for intestinal flora translocation and the development of secondary infection of the necrotic tissue, which can result in sepsis and late MOF. Many recommendations have been made regarding SAP management and its complications. However, despite the reduction in overall mortality in the last decade, SAP is still associated with high mortality. In the majority of cases, sterile necrosis should be managed conservatively, whereas in infected necrotizing pancreatitis, the infected non-vital solid tissue should be removed to control the sepsis. Intervention should be delayed for as long as possible to allow better demarcation and liquefaction of the necrosis. Currently, the step-up approach (delay, drain, and debride) may be considered as the reference standard intervention for this disorder. PMID:25320523

    A healthy 18-year-old girl presented to a local emergency room with 48 h of abdominal pain and vomiting. A radiological and biochemical diagnosis of moderate acute pancreatitis was made. Bloodwork demonstrated prominent hypertriglyceridaemia (HTG) of 19.5 mmol/L (severe HTG: 11.2-22.4), detectable urine ketones and a random blood glucose of 13 mmol/L dropping to 10.5 mmol/L on repeat (normal random Ketone levels were deemed consistent with fasting ketosis after 48 h of vomiting. There was no known history of diabetes in the patient. Management included aggressive rehydration and pain control, yet the patient rapidly decompensated into shock requiring intensive care unit support. Blood gases revealed severe metabolic acidosis (pH 6.99) and unsuspected underlying diabetic ketoacidosis was diagnosed. The HTG gradually resolved following intravenous fluids and insulin infusion with slower correction of the metabolic acidosis. Importantly, her glycated haemoglobin was 12%, indicating the silent presence of chronic glucose elevations.

    According to the revised Atlanta classification, severe and moderately severe acute pancreatitis (AP) includes patients with pancreatic and peripancreatic collections with or without organ failure. These collections suggest the presence of pancreatic juice leakage. The aim of this study was to evaluate the efficacy of a percutaneous catheter drainage (PCD) protocol designed to control leakage and decrease disease severity. Among 663 patients with clinical AP, 122 were classified as moderately severe or severe AP (all had collections). The computed tomography severity index (CTSI) score was calculated. The indication for PCD was based on progressive clinical signs and symptoms. Drain patency, position, and need for additional drainage sites were assessed using CT scans and drain studies initially every 3 days using a proactive protocol. Drain fluid was examined for amylase concentration and microbiological culture. Clinicopathological variables for patients with and without PCD were compared. Since there was no mortality, we used prolonged drainage time to measure the success of PCD. Within the group treated with PCD, variables that resulted in prolonged drainage time were analyzed. PCD was used in 47/122 (39 %) patients of which 33/47 (70 %) had necrosis. PCD cases had a median CTSI of 8 and were classified as moderately severe AP (57 %) and severe AP (43 %). Inhospital mortality was zero. Surgical necrosectomy was not required for patients with necrosis. Independent risk factors for prolonged drainage time were persistent organ failure >48 h (P = 0.001), CTSI 8-10 (P = 0.038), prolonged duration of amylase-rich fluid in drains (P drainage fluid resulting in a mortality rate of zero.

    The management of uncomplicated (Modified Hinchey Classification Ia) acute diverticulitis (AD) has become increasingly conservative, with a focus on symptomatic relief and supportive management. Clear criteria for patient selection are required to implement this safely. This retrospective study aimed to identify risk factors for severe clinical course in patients with uncomplicated AD. Patients admitted to General Surgery at two New Zealand tertiary centres over a period of 18 months were included. Univariate and multivariate analyses were carried out in order to identify factors associated with a more severe clinical course. This was defined by three endpoints: need for procedural intervention, admission >7 days and 30-day readmission; these were analysed separately and as a combined outcome. Uncomplicated AD was identified in 319 patients. Fifteen patients (5%) required procedural intervention; this was associated with SIRS (OR 3.92). Twenty-two (6.9%) patients were admitted for >7 days; this was associated with patient-reported pain score >8/10 (OR 5.67). Thirty-one patients (9.8%) required readmission within 30 days; this was associated with pain score >8/10 (OR 6.08) and first episode of AD (OR 2.47). Overall, 49 patients had a severe clinical course, and associated factors were regular steroid/immunomodulator use (OR 4.34), pain score >8/10 (OR 5.9) and higher temperature (OR 1.51) and CRP ≥200 (OR 4.1). SIRS, high pain score and CRP, first episode and regular steroid/immunomodulator use were identified as predictors of worse outcome in uncomplicated AD. These findings have the potential to inform prospective treatment decisions in this patient group.

    AIM: To investigate the role of prophylactic antibiotics in the reduction of mortality of severe acute pancreatitis (SAP) patients, which is highly questioned by more and more randomized controlled trials (RCTs) and meta-analyses. METHODS: An updated meta-analysis was performed. RCTs comparing prophylactic antibiotics for SAP with control or placebo were included for meta-analysis. The mortality outcomes were pooled for estimation, and re-pooled estimation was performed by the sensitivity analysis of an ideal large-scale RCT. RESULTS: Currently available 11 RCTs were included. Subgroup analysis showed that there was significant reduction of mortality rate in the period before 2000, while no significant reduction in the period from 2000 [Risk Ratio, (RR) = 1.01, P = 0.98]. Funnel plot indicated that there might be apparent publication bias in the period before 2000. Sensitivity analysis showed that the RR of mortality rate ranged from 0.77 to 1.00 with a relatively narrow confidence interval (P antibiotic prophylaxis. CONCLUSION: Current evidences do not support prophylactic antibiotics as a routine treatment for SAP, but the potentially benefited sub-population requires further investigations. PMID:22294832

    Lactic acidosis is a recognized event in adult patients with acute severe asthma (ASA). Only a few cases have been reported in children. Hereinafter is reported the case of a 2-year-old girl hospitalized in the pediatric intensive care unit for ASA, which was treated with high-flow oxygen therapy and intravenous methylprednisolone and salbutamol. During hospitalization, she had metabolic acidosis with a 7.29 pH, a 26mmHg hypocapnia, and a decrease in bicarbonates to 12 mmol/L. The anion gap was increased to 20 mmol/L and lactates to 8 mmol/L. The work-up for a congenital metabolic disease was normal. Progression was propitious with spontaneous improvement of lactic acidosis, and the child was discharged from the intensive care unit after 72 h. The origin of lactic acidosis during ASA seems to be multifactorial. Although its recovery can be spontaneous, it is important to know how to identify it because it can worsen respiratory symptoms and can lead to incongruous therapeutic escalation.

    AIM: To report the incidence of avascular osteonecrosis (AVN) in severe acute respiratory syndrome (SARS) patients. MATERIALS AND METHODS: Sixty-seven SARS patients who had large joint pain between March 2003 and May 2003 underwent both plain radiographs and magnetic resonance imaging (MRI) examination on the same day. All patients received steroids and ribavirin treatment. All plain radiographs and MR images were analysed by two experienced musculoskeletal radiologists. Any abnormalities, location, extent, morphology, the number, size and signal intensity of lesions were evaluated. RESULTS: Twenty-eight patients were identified with AVN, The mean time to diagnosis of AVN was 119 days after the onset of SARS, or 116 days after steroid use. Three patients had early bilateral AVN of the femoral head, four patients of one femoral head, five patients of the bilateral hips and knees, four patients of the ipsilateral hip and knees, 10 patients of the knee(s), one patient of the right proximal fibula, and one patient of the knees and talus. Results of hip, knee and ankle plain radiographs were negative. CONCLUSION: AVN can occur in the patients with SARS. AVN had a strong association with steroid use. More studies are required to confirm whether the virus itself can also lead to AVN.

    The aim of this study was to investigate the protective effect of polyenoylphosphatidylcholine (PPC) in rats with severe acute pancreatitis (SAP) and its mechanism. Seventy-two clean, conventional Sprague-Dawley rats were randomly divided into 4 groups (SAP; sham operation [SO], SAP + PPC, and SO + PPC; n = 18 per group). The SAP model was induced by injecting 4% sodium taurocholate (1 mL/kg) into the biliopancreatic duct. Animals in the SO groups underwent laparotomy and biliopancreatic duct puncture without fluid injection. Polyenoylphosphatidylcholine (50 mg/kg) was injected through the penis dorsal vein. Pancreatic acinar cell membrane fluidity and pancreatic tissue calcium pump activity were measured through fluorescence polarization and quantization of phosphonium ions, whereas pancreatic tissue superoxide dismutase and malondialdehyde were detected through xanthine oxidase method and thiobarbituric acid colorimetric analysis method, respectively. The SAP + PPC group had significantly improved pathologic pancreas; increased in pancreatic acinar cell membrane fluidity, pancreatic tissue Ca-Mg-ATPase activity, and superoxide dismutase; as well as decreased in malondialdehyde, ascites volume, and serum amylase compared with the SAP group. Polyenoylphosphatidylcholine could reduce the damage to the pancreas through increasing pancreatic acinar cell membrane fluidity and pancreatic tissue calcium pump activity. Polyenoylphosphatidylcholine also scavenges oxygen free radicals and reduces lipid peroxide levels.

    Severe acute pancreatitis (SAP) is hard to treat for the abrupt onset, critical condition and complicated pathophysiology. Historically, the treatment strategy of SAP hovered between surgical intervention and conservative treatment. At the turn of the 20(th) century, SAP was reported to be cured by surgical intervention in a series cases, which lead to the dominance of surgical intervention in SAP treatment. Subsequently, SAP was documented to respond to nonoperative therapy. A wave of conservatism emerged, and surgical intervention for SAP was rarely practiced for the next 3 decades. However, surgeons refined the indications and considered new approaches for surgical treatment in 1960s because of the poor outcomes of conservation, and surgical interventions was mainly performed at early stage of SAP. However, a series of prospective studies showed that conservative treatment of patients with sterile pancreatic necrosis is superior to surgical intervention, and that delayed intervention provide improved outcomes in 1990s, which changed the treatment concept of SAP again. The modern treatment concept formed during the progression: organ supportive care dominates in the early stage of the disease, and surgical intervention should be performed at late stage with proper indications. Despite the advances in treatment, the morbidity of SAP is still 5%-20%, which suggests the pancreatic surgeons' exploration in the future.

    We investigated the existence of an ischemic penumbra, which indicates ischemic but still viable lesion, in the early stage of severe acute pancreatitis (SAP). Seventy-one consecutive patients with SAP were enrolled. We divided the pancreas into three regions, the head, body and tail, and measured pancreatic blood flow (F V ) and volume (V D ) in each region by perfusion CT with one compartment method within three days after the onset of symptoms. Three weeks later, all patients underwent contrast-enhanced CT to diagnose each region for the development of pancreatic necrosis. Of the 227 pancreatic regions from 71 SAP patients, 30 regions were diagnosed as positive for pancreatic necrosis. F V and V D in regions that developed pancreatic necrosis were significantly lower than those in regions without necrosis (35.7±50.7 vs. 197.0±227.6 ml/min, p V D V ≥37.5 ml/min and V D V D ≥3.4%, 4 (11.7%) developed necrosis. None of 141 regions with F V ≥37.5 ml/min and V D ≥3.4% developed necrosis. If F V or V D was low, not all regions developed pancreatic necrosis; therefore, we considered that these regions could include zones of ischemic penumbra. (author)

    Full Text Available This paper provides a review of a recently published series of studies that give a detailed and comprehensive documentation of the severe acute respiratory syndrome (SARS epidemic in mainland China, which severely struck the country in the spring of 2003. The epidemic spanned a large geographical extent but clustered in two areas: first in Guangdong Province, and about 3 months later in Beijing with its surrounding areas. Reanalysis of all available epidemiological data resulted in a total of 5327 probable cases of SARS, of whom 343 died. The resulting case fatality ratio (CFR of 6.4% was less than half of that in other SARS-affected countries or areas, and this difference could only partly be explained by younger age of patients and higher number of community acquired infections. Analysis of the impact of interventions demonstrated that strong political commitment and a centrally coordinated response was the most important factor to control SARS in mainland China, whereas the most stringent control measures were all initiated when the epidemic was already dying down. The long-term economic consequence of the epidemic was limited, much consumption was merely postponed, but for Beijing irrecoverable losses to the tourist sector were considerable. An important finding from a cohort study was that many former SARS patients currently suffer from avascular osteo­necrosis, as a consequence of the treatment with corticosteroids during their infection. The SARS epidemic provided valuable information and lessons relevant in controlling outbreaks of newly emerging infectious diseases, and has led to fundamental reforms of the Chinese health system. In particular, a comprehensive nation-wide internet-based disease reporting system was established.

    Acute severe colitis is a potentially lethal medical emergency and, even today, its treatment remains a challenge for clinicians and surgeons. Intravenous corticoid therapy, which was introduced into the therapeutic arsenal in the 1950s, continues to be the first-line treatment and, for patients who are refractory to this, the rescue therapy may consist of clinical measures or emergency colectomy. To evaluate the indications for and results from drug rescue therapy (cyclosporine, infliximab and tacrolimus), and to suggest a practical guide for clinical approaches. The literature was reviewed using the Medline/PubMed, Cochrane library and SciELO databases, and additional information from institutional websites of interest, by cross-correlating the following keywords: acute severe colitis, fulminating colitis and treatment. Treatments for acute severe colitis have avoided colectomy in 60-70% of the cases, provided that they have been started early on, with multidisciplinary follow-up. Despite the adverse effects of intravenous cyclosporine, this drug has been indicated in cases of greater severity with an imminent risk of colectomy, because of its fast action, short half-life and absence of increased risk of surgical complications. Therapy using infliximab has been reserved for less severe cases and those in which immunosuppressants are being or have been used (AZA/6-MP). Indication of biological agents has recently been favored because of their ease of therapeutic use, their good short and medium-term results, the possibility of maintenance therapy and also their action as a "bridge" for immunosuppressant action (AZA/6-MP). Colectomy has been reserved for cases in which there is still no response five to seven days after rescue therapy and in cases of complications (toxic megacolon, profuse hemorrhage and perforation). Patients with a good response to rescue therapy who do not undergo emergency operations should be considered for maintenance therapy using

    Full Text Available Oxygen therapy might increase damaged tissue oxygenation, turn on the aerobic pathway, and save neurons from death and could improve clinical outcome of the patients with stroke and head trauma. Hyperbaric oxygen therapy is accompanied by some unfavorable effects. Results of normobaric oxygen therapy on clinical outcomes of patients with stroke were controversial up till now.  This study was therefore designed to evaluate effects of normobaric hyperoxia on clinical outcomes of patients with severe acute stroke. A total of 52 consecutive patients with stroke with the inclusion criteria of the study were entered into this randomized controlled clinical trial. The patients in the case group underwent oxygen therapy with Venturi mask for first 12 hours of admission. The patients were examined for neurologic defects at the time of discharge and after six months using both Barthel and modified Rankin Scale (mRS neurologic disability scoring systems. There was no significant sex difference between the two groups (P=0.5. There was no statistically significant difference between ischemic-hemorrhagic stroke constitutions of two groups (P=0.2. There were no significant difference in Barthel index scores of both groups at the time of discharge as well as the follow-up examination (P=0.7 According to the mRS scoring system, there was no difference between the patients of both groups at the time of admission (P= 0.8, however after treatment there was a significant difference between mRS scores of the treated group compared to the controls (P=0.04. According to the results of this study, normobaric oxygen therapy in the first 12 hours of accident could improve long time outcome of the patients with either ischemic or hemorrhagic stroke.

    Solcoseryl, a deproteinized extract from calf blood containing various biologically active substances, has been reported to promote the healing of skin wounds and gastric ulceration In this study, the gastroprotective effects of Solcoseryl vis-a-vis acute gastric mucosal damage were examined in rats. Solcoseryl significantly reduced the formation of acute lesions induced by intragastric application of absolute ethanol or acidified taurocholate and by water immersion and restraint stress, but failed to affect those caused by acidified aspirin. Since Solcoseryl did not offer protection in the absence of mucosal prostaglandins (PG) e.g. in aspirin-induced gastric damage, it is likely that PG may be involved in the observed gastroprotective activity of the drug. Solcoseryl failed to affect gastric acid or pepsin secretion, but increased mucosal blood flow. Thus PG generated by Solcoseryl might contribute to the maintenance of the observed mucosal microcirculation and the prevention of lesion formation by corrosive substances and stress conditions.

    Despite extensive research and clinical efforts made in the management of acute pancre-atitis during the past few decades, to date no effective cure is available and the mortality from severe acute pancre-atitis remains high. Given that lung is the primary cause of early death in acute pancreatitis patients, novel therapeutic approaches aiming to prevent lung injury have become a subject of intensive investigation. In a previous study, we demonstrated that sivelestat, a specific inhibitor of neutrophil elastase, is effective in protecting against lung failure in rats with taurocholate-induced acute pancreatitis. As part of the analyses extended from that study, the present study aimed to evaluate the role of sivelestat and/or resveratrol in the protection against acute pancreatitis-associated lung injury. The extended analyses demonstrated the following: (1) sodium taurocholate induced apparent lung injury and dysfunction manifested by histological anomalies, including vacuolization and apoptosis of the cells in the lung, as well as biochemical aberrations in the blood (an increase in amylase concentration and a decrease in partial arterial oxygen pressure) and increases in activities of reactive oxygen species, interleukin 6, myeloperoxidase, neutrophil elastase, lung edema, bronchotracho alveolar lavage protein concentration, and bronchotracho alveolar lavage cell infiltration in the lung; and (2) in lung tissues, either sivelestat or resveratrol treatment effectively attenuated the taurocholate-induced abnormalities in all parameters analyzed except for serum amylase concentration. In addition, combined treatment with both sivelestat and resveratrol demonstrated additive protective effects on pancreatitis-associated lung injury compared with single treatment.

    Binge eating occurs in patients with eating disorders and can result in metabolic complications, leading to gastric rupture or necrosis. However, organ failure as acute renal failure is rarely observed. We report the case of an overeating episode resulting in massive gastric dilatation and acute renal failure with abdominal pressure and bilateral ureteral obstruction. The outcome was favorable with gastric aspiration and fasting. Copyright © 2017 Elsevier Inc. All rights reserved.

    Severe acute pancreatitis (SAP) can often be complicated by acute lung injury (ALI) and acute respiratory distress syndrome (ARDS), leading to increased mortality. Early blood purification clears inflammatory cytokines and promotes immune function recovery. Here we evaluated the usefulness of this therapy in SAP complicated by ALI. 32 patients received routine treatment (control group), whereas other 32 patients received routine treatment and early blood purification therapy (study group). We evaluated respiratory indexes (PaO2, PaO2/FiO2, alveolar-arterial oxygen difference, intrapulmonary arteriovenous shunt percentage, and respiratory rate), blood biochemical (creatinine, blood urea nitrogen, alanine aminotransferase, and lactate levels) and inflammatory (CRP, IL-10, TNF-α, and IL-10/TNF-α ratio) markers, and prognostic outcomes (multiple organ dysfunction syndrome [MODS] and APACHE II scores) before and 72 hours after the treatment. We also documented mechanical ventilation use, occurrence of MODS and ARDS, and mortality rates. There were no deaths. Mechanical ventilation was used in a similar percentage of patients in either group. Treatment in study group led to a faster and better recovery of respiratory indexes, and less pronounced changes in the levels of blood urea nitrogen and alanine aminotransferase. Inflammatory markers also normalized better in the study group. Furthermore, MODS and APACHE II scores decreased to a greater extent in the study group, paralleled by a lower occurrence of MPDS and ARDS. Early blood purification therapy improves respiratory function and inflammatory markers in patients with SAP complicated by ALI, and decreases the occurrence of MODS and ARDS.

  15. Prediction and Prevention of Acute Kidney Injury after Cardiac Surgery

    Directory of Open Access Journals (Sweden)

    2016-01-01

    Full Text Available The incidence of acute kidney injury after cardiac surgery (CS-AKI ranges from 33% to 94% and is associated with a high incidence of morbidity and mortality. The etiology is suggested to be multifactorial and related to almost all aspects of perioperative management. Numerous studies have reported the risk factors and risk scores and novel biomarkers of AKI have been investigated to facilitate the subclinical diagnosis of AKI. Based on the known independent risk factors, many preventive interventions to reduce the risk of CS-AKI have been tested. However, any single preventive intervention did not show a definite and persistent benefit to reduce the incidence of CS-AKI. Goal-directed therapy has been considered to be a preventive strategy with a substantial level of efficacy. Many pharmacologic agents were tested for any benefit to treat or prevent CS-AKI but the results were conflicting and evidences are still lacking. The present review will summarize the current updated evidences about the risk factors and preventive strategies for CS-AKI.

    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.

    An important goal of the US DOE reactor development program is to conceptualize advanced safety design features for a demonstration Sodium Fast Reactor (SFR). The treatment of severe accidents is one of the key safety issues in the design approach for advanced SFR systems. It is necessary to develop an in-depth understanding of the risk of severe accidents for the SFR so that appropriate risk management measures can be implemented early in the design process. This report presents the results of a review of the SFR features and phenomena that directly influence the sequence of events during a postulated severe accident. The report identifies the safety features used or proposed for various SFR designs in the US and worldwide for the prevention and/or mitigation of Core Disruptive Accidents (CDA). The report provides an overview of the current SFR safety approaches and the role of severe accidents. Mutual understanding of these design features and safety approaches is necessary for future collaborations between the US and its international partners as part of the GEN IV program. The report also reviews the basis for an integrated safety approach to severe accidents for the SFR that reflects the safety design knowledge gained in the US during the Advanced Liquid Metal Reactor (ALMR) and Integral Fast Reactor (IFR) programs. This approach relies on inherent reactor and plant safety performance characteristics to provide additional safety margins. The goal of this approach is to prevent development of severe accident conditions, even in the event of initiators with safety system failures previously recognized to lead directly to reactor damage.

  1. Impaired Bile Acid Homeostasis in Children with Severe Acute Malnutrition.

    Directory of Open Access Journals (Sweden)

    Ling Zhang

    Full Text Available Severe acute malnutrition (SAM is a major cause of mortality in children under 5 years and is associated with hepatic steatosis. Bile acids are synthesized in the liver and participate in dietary fat digestion, regulation of energy expenditure, and immune responses. The aim of this work was to investigate whether SAM is associated with clinically relevant changes in bile acid homeostasis.An initial discovery cohort with 5 healthy controls and 22 SAM-patients was used to identify altered bile acid homeostasis. A follow up cohort of 40 SAM-patients were then studied on admission and 3 days after clinical stabilization to assess recovery in bile acid metabolism. Recruited children were 6-60 months old and admitted for SAM in Malawi. Clinical characteristics, feces and blood were collected on admission and prior to discharge. Bile acids, 7α-hydroxy-4-cholesten-3-one (C4 and FGF-19 were quantified.On admission, total serum bile acids were higher in children with SAM than in healthy controls and glycine-conjugates accounted for most of this accumulation with median and interquartile range (IQR of 24.6 μmol/L [8.6-47.7] compared to 1.9 μmol/L [1.7-3.3] (p = 0.01 in controls. Total serum bile acid concentrations did not decrease prior to discharge. On admission, fecal conjugated bile acids were lower and secondary bile acids higher at admission compared to pre- discharge, suggesting increased bacterial conversion. FGF19 (Fibroblast growth factor 19, a marker of intestinal bile acid signaling, was higher on admission and was associated with decreased C4 concentrations as a marker of bile acid synthesis. Upon recovery, fecal calprotectin, a marker of intestinal inflammation, was lower.SAM is associated with increased serum bile acid levels despite reduced synthesis rates. In SAM, there tends to be increased deconjugation of bile acids and conversion from primary to secondary bile acids, which may contribute to the development of liver disease.

  2. Allopurinol-induced Severe Hypersensitivity with Acute Renal Failure

    2005-05-01

    Full Text Available A 62-year-old male was sent to the emergency room due to a high fever and generalized skin rash after taking allopurinol for 9 days. Physical examination was normal except for the generalized skin rash presenting with erythematous macules. Complete blood count showed leukocytosis with eosinophilia. Blood biochemistry showed impaired renal and hepatic function. Pathologic examination concluded that the skin rash was erythema multiforme. These findings met the diagnostic criteria for allopurinol-induced hypersensitivity syndrome (AHS. Our patient not only had the most common skin lesion but soon developed acute renal failure that required intermittent hemodialysis, despite rapid discontinuation of allopurinol and adequate hydration and steroid therapy. No other causes of acute renal failure were found. Renal impairment was the worst part of the patient's condition and he never completely recovered. AHS should be considered in the differential diagnosis of acute renal and hepatic failure in patients with evidence of allergy and recent use of allopurinol.

  3. Prevention of heavy missiles during severe PWR accidents

    1994-01-01

    For future pressurized water reactors, which should be designed against core melt down accidents, missiles generated inside the containment present a severe problem for its integrity. The masses and geometries of the missiles as well as their velocities may vary to a great extend. Therefore, a reliable proof of the containment integrity is very difficult. To overcome this problem the potential sources of missiles are discussed. In section 5 it is concluded that the generation of heavy missiles must be prevented. Steam explosions must not damage the reactor vessel head. Thus fragments of the head cannot become missiles endangering the containment shell. Furthermore, during a melt-through failure of the reactor vessel under high pressure the resulting forces must not catapult the whole vessel against the containment shell. Only missiles caused by hydrogen explosions might be tolerable, but shielding structures which protect the containment shell might be required. Here further investigations are necessary. Finally, measures are described showing that the generation of heavy missiles can indeed be prevented. In section 6 investigations are explained which will confirm the strength of the reactor vessel head. In section 7 a device is discussed keeping the fragments of a failing reactor vessel at its place. (author). 12 refs., 8 figs

    Stroke is the main cause of disability in high-income countries and ranks second as a cause of death worldwide. Infections occur frequently after stroke and may adversely affect outcome. Preventive antibiotic therapy in the acute phase of stroke may reduce the incidence of infections and improve outcome. In the previous version of this Cochrane Review, published in 2012, we found that antibiotics did reduce the risk of infection but did not reduce the number of dependent or deceased patients. However, included studies were small and heterogeneous. In 2015, two large clinical trials were published, warranting an update of this Review. To assess the effectiveness and safety of preventive antibiotic therapy in people with ischaemic or haemorrhagic stroke. We wished to determine whether preventive antibiotic therapy in people with acute stroke:• reduces the risk of a poor functional outcome (dependency and/or death) at follow-up;• reduces the occurrence of infections in the acute phase of stroke;• reduces the occurrence of elevated body temperature (temperature ≥ 38° C) in the acute phase of stroke;• reduces length of hospital stay; or• leads to an increased rate of serious adverse events, such as anaphylactic shock, skin rash, or colonisation with antibiotic-resistant micro-organisms. We searched the Cochrane Stroke Group Trials Register (25 June 2017); the Cochrane Central Register of Controlled Trials (CENTRAL; 2017, Issue 5; 25 June 2017) in the Cochrane Library; MEDLINE Ovid (1950 to 11 May 2017), and Embase Ovid (1980 to 11 May 2017). In an effort to identify further published, unpublished, and ongoing trials, we searched trials and research registers, scanned reference lists, and contacted trial authors, colleagues, and researchers in the field. Randomised controlled trials (RCTs) of preventive antibiotic therapy versus control (placebo or open control) in people with acute ischaemic or haemorrhagic stroke.

  7. Is the chemical prevention of gingivitis necessary to prevent severe periodontitis?

    Science.gov (United States)

    Sheiham, A

    1997-10-01

    Gingival inflammation seldom causes discomfort, social embarrassment or loss of function. As most sites with gingival inflammation do not progress to severe periodontal disease, gingivitis should not be considered a public health problem. Periodontitis is always preceded by gingivitis. But most gingivitis remains stable for years without progressing to periodontitis. The number of gingivitis sites that do convert is small. The levels of oral cleanliness achieved by the majority of populations in industrialized countries are below the threshold for severe destructive periodontal disease of personal and public health concern. Because methods of measuring the progression of periodontal disease are unreliable, definitive answers regarding conversion of gingivitis to severe periodontitis are lacking. Gingival inflammation frequently remains contained; most gingivitis remains stable for years without progressing to periodontitis. Decreasing gingivitis does reduce shallow pocketing, but the effect on severe periodontitis is not clear. Although the underlying justification for the reduction of plaque is to reduce gingival inflammation to prevent or reduce severe periodontitis and tooth loss, the basis for the approach is equivocal. A reasonably high level of plaque appears to be compatible with acceptably low levels of periodontal disease. Reducing nonspecific plaque levels to such levels is therefore a rational goal. The conventional methods of controlling periodontal disease involve mechanical removal of plaque and calculus. A complimentary ecological approach, using chemicals, would be to alter the environment of the pocket to prevent growth of putative pathogens. Any ecological approach should be sensitive to the dangers of disrupting the natural ecology of dental plaque. Some antimicrobial and antimetabolic agents such as fluoride, chlorhexidine and triclosan and zinc citrate can selectively suppress certain organisms or inhibit bacterial proteases implicated in

  8. Enhanced Severe Transient Analysis for Prevention Technical Program Plan

    2014-09-01

    This document outlines the development of a high fidelity, best estimate nuclear power plant severe transient simulation capability that will complement or enhance the integral system codes historically used for licensing and analysis of severe accidents. As with other tools in the Risk Informed Safety Margin Characterization (RISMC) Toolkit, the ultimate user of Enhanced Severe Transient Analysis and Prevention (ESTAP) capability is the plant decision-maker; the deliverable to that customer is a modern, simulation-based safety analysis capability, applicable to a much broader class of safety issues than is traditional Light Water Reactor (LWR) licensing analysis. Currently, the RISMC pathway’s major emphasis is placed on developing RELAP-7, a next-generation safety analysis code, and on showing how to use RELAP-7 to analyze margin from a modern point of view: that is, by characterizing margin in terms of the probabilistic spectra of the “loads” applied to systems, structures, and components (SSCs), and the “capacity” of those SSCs to resist those loads without failing. The first objective of the ESTAP task, and the focus of one task of this effort, is to augment RELAP-7 analyses with user-selected multi-dimensional, multi-phase models of specific plant components to simulate complex phenomena that may lead to, or exacerbate, severe transients and core damage. Such phenomena include: coolant crossflow between PWR assemblies during a severe reactivity transient, stratified single or two-phase coolant flow in primary coolant piping, inhomogeneous mixing of emergency coolant water or boric acid with hot primary coolant, and water hammer. These are well-documented phenomena associated with plant transients but that are generally not captured in system codes. They are, however, generally limited to specific components, structures, and operating conditions. The second ESTAP task is to similarly augment a severe (post-core damage) accident integral analyses code

    The degree of agreement between patient- and clinician-rated scales of depressive severity varies widely. This study analyzed agreement between commonly used depression rating scales in the Prevention of Recurrent Episodes of Depression with Venlafaxine Extended Release (ER) for Two Years (PREVENT) trial. The PREVENT trial was a multiphase, randomized, double-blind study of patients with recurrent major depressive disorder. This secondary analysis evaluated acute (10weeks) and continuation phase (6months) data. Pearson correlation coefficients at each acute-phase (weekly) and continuation-phase (monthly) visit were calculated for patient-rated (30-item Inventory of Depressive Symptomatology-Self-Rated [IDS-SR30] and clinician-rated (17-item Hamilton Rating Scale for Depression [HAM-D17] and Clinical Global Impressions-Severity [CGI-S]) measures and for response and remission. Data from 1,047 patients were analyzed. The respective correlation coefficients at baseline, week 10, and month 6 were: IDS-SR30: HAM-D17: 0.46, 0.75, 0.70; and for IDS-SR30: CGI-S 0.28, 0.67, 0.65. Agreement between IDS-SR30- and HAM-D17-defined remission and response was relatively poor: week 10, 0.52 and 0.34, respectively; month 6, 0.45 and 0.32, respectively. These findings suggest that patient-rated measures of depression severity do not correspond strongly with clinician ratings, and are particularly poor prior to the initiation of treatment.

    Full text: Recent literature reviews have demonstrated the limited efficacy of targeted supplementary feeding programmes aimed at both treating and preventing moderate acute malnutrition (MAM), with high rates of defaulting, low coverage and high associated costs. There is a growing interest in a) reviewing and improving protocols / tools for the management of acute malnutrition and b) increasing the quality and variety of products available for the treatment / prevention of moderate acute malnutrition. There is however, varying evidence on the impact of nutritional products aimed at preventing or treating acute malnutrition, or on the comparative efficacy of different products. Following several literature reviews and operational research with varying results, there is increasing consensus that MAM should be tackled not only through products, and that clearer guidance should be provided on broader preventive strategies, such as optimal infant and young child feeding (IYCF) and caregiving practices, optimal maternal nutrition, counselling, social protection, food security and livelihoods, and water, sanitation and hygiene (WASH). The CMAM Forum has commissioned Technical Briefs which aim to summarise current thinking and practice relating to preventive approaches to MAM, looking at the role of both nutrition-specific and nutrition-sensitive interventions. The work is being launched in January 2014 and results will be available for presentation at the IAEA MAM Symposium in May 2014. The briefs aim to provide: • An overview of approaches to preventing MAM across different sectors (e.g. agriculture, health, IYCF, social protection, water and sanitation) and in different contexts. • A review of current knowledge including: – Evidence from systematic and literature reviews. – Existing approaches and practice for prevention of MAM. – Current guidance on making programmatic choices relating to MAM prevention interventions and decision-making frameworks.

    Although injury severity and parental stress are strong predictors of posttraumatic adjustment in young children after burns, little is known about the interplay of these variables. This study aimed at clarifying mediation processes between injury severity and mother's, father's, and young child's acute stress. Structural equation modeling was used to examine the relationships between injury severity and parental and child acute stress. Parents of 138 burn-injured children (ages 1-4 years) completed standardized questionnaires on average 19 days postinjury. Sixteen children (11.7%) met Diagnostic and Statistical Manual of Mental Disorders, 5th edition, preschool criteria for posttraumatic stress disorder (excluding time criterion). The model revealed a significant mediation of maternal acute stress, with the effect of injury severity on a child's acute stress mediated by maternal acute stress. Paternal acute stress failed to serve as a mediating variable. Our findings confirm mothers' crucial role in the posttraumatic adjustment of young children. Clinically, mothers' acute stress should be monitored. © The Author 2017. Published by Oxford University Press on behalf of the Society of Pediatric Psychology. All rights reserved.

    2001-09-01

    To present clinical information relevant to acute respiratory distress syndrome (ARDS) and its appearance in chiropractic acute care practice. The National Library of Medicine MEDLINE database was used, along with the bibliographies of selected articles and textbooks commonly found in chiropractic college libraries and bookstores. Clinical studies from the English literature were selected if they pertained to incidence, clinical relevancy, or the association of ARDS with commonly-seen diagnoses in chiropractic neuromusculoskeletal or orthopedic practice. All relevant studies identified by the search were evaluated based on information pertinent to chiropractic management of acute care patients. ARDS is a pulmonary distress syndrome with a high mortality rate. Recognizable indications for the possible development of ARDS include chest pain, head injury, and thoracic spine pain with or without trauma. Clinical evaluation, radiographic findings, and laboratory findings are presented to assist practitioners in identifying this disease process of multiple etiology. A study of the basic pathophysiologic processes that occur in the formation of ARDS is presented to help practitioners gain clinical appreciation. Strategies for preventing respiratory distress in chiropractic patients are also presented and include use of the postural position and the clinical maxim of "slow, deep breathing despite pain" to lessen incident rates of subjects at risk. Although ARDS may not be prevalent in chiropractic practice, it is important for physicians to be aware of the clinical basics (including its pathophysiology), its medical significance, and the preventive strategies that may be used to minimize its occurrence. This basic understanding will further advance knowledge of this disease complex.

    The Japanese guidelines for acute otitis media in children recommend classifying acute otitis media by age, manifestations and local findings, and also recommend myringotomy for moderate-grade cases with severe local findings, severe-grade cases, and treatment-resistant cases. The heptavalent pneumococcal conjugate vaccine was released in Japan in February 2010. In Hiroshima City, public funding allowing free inoculation with this vaccine was initiated from January 2011, and the number of vaccinated individuals has since increased dramatically. This study investigated changes in the number of myringotomies performed to treat acute otitis media during the 5-year period from January 2008 to December 2012 at two hospitals and five clinics in the Asa Area of Hiroshima City, Japan. A total of 3,165 myringotomies for acute otitis media were performed. The rate of procedures per child-year performed in otitis media in 1-year-old infants decreased significantly in the 2 years after the introduction of public funding for heptavalent pneumococcal conjugate vaccine compared to all years before introduction (potitis media in reducing the financial burden of myringotomy. In addition, this vaccine may help prevent acute otitis media with severe middle ear inflammation in 1-year-old infants.

    Moderate consumption of red wine is associated with fewer cardiovascular events. We investigated whether red wine consumption counteracts the adverse vascular effects of cigarette smoking. Participants smoked 3 cigarettes alone or after drinking a titrated volume of red wine. Clinical chemistry, blood counts, plasma cytokine enzyme-linked immunosorbent assays, immunomagnetic separation of CD14 + monocytes for gene expression analysis, fluorescence-activated cell sorting for microparticles, and isolation of circulating mononuclear cells to measure telomerase activity were performed, and urine cotinine levels were quantified. Compared with baseline, leukocytosis (P = .019), neutrophilia (P <.001), lymphopenia (P <.001), and eosinopenia (P = .008) were observed after only smoking. Endothelial and platelet-, monocyte-, and leukocyte-derived microparticles (P <.001 each) were elevated. In monocytes, messenger RNA expression of interleukin (IL)-6 (2.6- ± 0.57-fold), tumor necrosis factor alpha (2.2- ± 0.62-fold), and IL-1b (2.3- ± 0.44-fold) were upregulated, as was IL-6 (1.2 ± 0.12-fold) protein concentration in plasma. Smoking acutely inhibited mononuclear cell telomerase activity. Markers of endothelial damage, inflammation, and cellular aging were completely attenuated by red wine consumption. Cigarette smoke results in acute endothelial damage, vascular and systemic inflammation, and indicators of the cellular aging processes in otherwise healthy nonsmokers. Pretreatment with red wine was preventive. The findings underscore the magnitude of acute damage exerted by cigarette smoking in "occasional lifestyle smokers" and demonstrate the potential of red wine as a protective strategy to avert markers of vascular injury.

    Severe Acute Liver Failure (ALF) is a life-threatening clinical syndrome characterized by hepatocyte necrosis, loss of hepatic architecture, and impairment of liver functions. One of the main causes of ALF is hepatotoxicity from chemical agents, which damage hepatocytes and result in increase of reactive oxygen species. The vitamin E isoform is the one with the strongest biological antioxidant activity. To evaluate the antioxidant effect of vitamin E in this ALF model. We used 56 rats (mean weight of 300 g) divided into eight groups, four groups assessed at 24 hours and 4 assessed at 48 hours after induction: control group (CO); Vitamin E (Vit. E); Thioacetamide (TAA) and Thioacetamide + Vitamina E (TAA+Vit.E). Rats were submitted to injections of thioacetamide (400 mg/kg i.p.) at baseline and 8 hours later. Vitamin E (100 mg/kg ip) was administered 30 minutes after the second dose of thioacetamide. The 48-hour group rats received two additional doses of vitamin E (24h and 36h). At 24h or 48 hours after the administration of the first dose of TAA, rats were weighed and anesthetized and their blood sampled for evaluation of liver integrity through enzymes aspartate aminotransferase (AST) and alanine aminotransferase (ALT). Liver tissue was sampled for assessment of lipid peroxidation (LPO) by the technique TBARS, antioxidant enzymes SOD, CAT, GPx and GST activity, levels of the NO 2 /NO 3 and histology by H&E in two times. The results were expressed as mean ± standard deviation and statistically analyzed by ANOVA followed by Student-Newman-Keuls, with P E, we observed a reduction in liver enzymes AST (U/L) (101.32±19.45 in 24 hours and 97.85±29.65 in 48 hours) related to the TAA group (469.56± 0.69 in 24 hours and 598.23±55.45 in 48 hours) and ALT (U/L) (76.59±8.56 in 24 hours and 68.47±6.49 in 48 hours) compared to the TAA group (312.21±10.23 in 24 hours and 359.15±17.58 in 48 hours). There was a reduction of LPO (nmol/mg Prot) in the TAA+Vit.E group (0

    To explore the four criteria, including bedside index for severity in acute pancreatitis(BISAP), Ranson score, modified CT severity index(MCTSI) and acute physiology and chronic health evaluation scoring systemⅡ(APACHE Ⅱ) in assessment of severity and prognosis of hyperlipidemic acute pancreatitis. A total of 326 patients with hyperlipidemic acute pancreatitis were studied retrospectively from August 2006 to July 2015. The discrepancy of the four criteria in assessment of severity and prognosis of hyperlipidemic acute pancreatitis was compared with chi-square test and receiver operating characteristic curve. The incidences of moderately severe acute pancreatitis and severe acute pancreatitis, local complications and mortality of patients with BISAP score≥3, Ranson score≥3, APACHE Ⅱ score≥8 and MCTSI score≥4 were significantly higher than BISAP score<3, Ranson score<3, APACHE Ⅱscore<8 and MCTSI<4 respectively (all P<0.05). As far as severity was concerned, the sensitivity and AUC of APACHEⅡ were 57% and 0.814, which were higher than the other systems. The second most sensitive criterion was BISAP. In assessment of local complications, the sensitivity and AUC of MCTSI were 68% and 0.791, which were higher than the other three. The most sensitive criterion to predict mortality was BISAP with sensitivity 89% and AUC 0.867, which was followed by APACHE Ⅱ. All four criteria can be used to determine the severity, local complications and mortality. Generally, BISAP is simple and easy to practice, and better than the other three.

    Acute intermittent prophyria (AIP) is an autosomal dominant disease that results from a defect in the enzyme porphobilinogen deaminase. Acute intermittent porphyria is the most common of hepatic porphyrias and can tax the therapeutic capabilities of the physician to the limit. Motor weakness is a major feature of an acute attack, and flaccid paralysis of all extremities can occur rapidly, within a matter of days. The acute attacks may be life threatening. Hematin (Heme Arginate) should be given early during an acute attack to prevent neurologic sequel. Hemodialysis and hemoperfusion have been tried in the treatment of acute attacks of AIP with success. As hematin is not available in India, a severe acute attack of AIP in a patient was managed with hemodialysis successfully. Later, hematin was imported and provided to the patient. An 18-year-old girl was admitted to our hospital with recurrent abdominal pain and 2 episodes of convulsions. She had undergone an appendectomy earlier at another hospital for abdominal pain. On evaluation, she had hyponatremia, episodic abnormal behavior, generalized muscle pain, hypertension, and sinus tachycardia. In view of the above clinical picture, a clinical diagnosis of acute intermittent porphyria was made. Her 24-hr urinary porphobilinogen was 90.8 mg/day (<2 mg-normal) and alpha amino levalunic acid was 108.8 mg/day (1-7 mg-normal), consistent with the diagnosis. Her hyponatremia was corrected. Arrangements were made to import hematin and she was managed with dextrose infusion. Meanwhile, she developed flaccid quardriparesis with urinary incontinence and bulbar palsy. Her brain MRI was normal. Her nerve conduction study was suggestive of motor radiculoneuropathy. Specific treatment for severe porphyric crisis was planned. She failed to improve with dextrose infusion alone. As hematin was not readily available in the country, other therapeutic options were considered. As few case reports of AIP being successfully treated with

    Severe acute respiratory syndrome (SARS) is a major infectious disease pandemic that occurred in early 2003, and one of the diagnostic criteria is the presence of chest radiographic findings. To describe the radiographic features of SARS in a cluster of affected children. The chest radiographs of four related children ranging in age from 18 months to 9 years diagnosed as having SARS were reviewed for the presence of air-space shadowing, air bronchograms, peribronchial thickening, interstitial disease, pleural effusion, pneumothorax, hilar lymphadenopathy and mediastinal widening. Ill-defined air-space shadowing was the common finding in all the children. The distribution was unifocal or multifocal. No other findings were seen on the radiographs. None of the children developed radiographic findings consistent with acute respiratory distress syndrome. All four children showed significant resolution of the radiographic findings 4-6 days after the initial radiograph. Early recognition of these features is important in implementing isolation and containment measures to prevent the spread of infection. SARS in children appears to manifest as a milder form of the disease as compared to adults. (orig.)

    Full Text Available Abhinav Deol, Voravit Ratanatharathorn, Joseph P UbertiDepartment of Oncology, Blood and Marrow Stem Cell Transplant Program, Barbara Ann Karmanos Cancer Institute, Wayne State University School of Medicine, Detroit, MI, USAAbstract: Acute graft-versus-host disease (aGVHD is an immunologically mediated inflammatory reaction, which continues to be a major cause of morbidity and mortality in patients undergoing allogeneic hematopoietic stem cell transplant. Although the occurrence and severity of this disease may be devastating, there is a proven immunologically mediated antitumor activity that accompanies the disease process, which has a beneficial effect on outcome. Animal models of graft-versus-host disease (GVHD have given us a conceptual model that has allowed a better understanding of the pathophysiology and offers a framework for understanding the complex interactions between antigen-presenting cells, donor T-cells, and cytokines in the development of aGVHD. It has also given us a model that allows testing of various strategies for prevention and treatment. New, innovative approaches for treatment and prevention of aGVHD including better donor selection with the use of sophisticated human leukocyte antigen typing, use of T-cell depletion, reduced-intensity transplant regimens, and improved pharmacologic immunosuppression have improved outcomes by decreasing the incidence and severity of aGVHD. However, the limitation of these strategies is that effective treatment and prevention of aGVHD is often accompanied by a concomitant rise in relapses, graft failure and infections, and ultimately no improvement in overall survival. Investigators are working on understanding the difference between GVHD and graft versus tumor effect, as this would be the key in improving outcomes for our patients. In this review, we will discuss the pathophysiology of aGVHD along with the preventative and treatment strategies.Keywords: acute GVHD, GVHD, acute graft

    1981-07-01

    Acute and recurrent herpes simplex was studied after infection in the ear of two outbred and five inbred strains of mice. In all strains tested there was clinical evidence of infection, and a proportion of the mice became latently infected in the cervical ganglia. Six weeks after infection, when attempts were made to induce recurrent desease by stripping the ears of the mice with cellophange tape, a proportion of animals of each strain developed recurrent disease, characterized by erythema in the skin. At monthly intervals thereafter, the ears were stripped again and, on each occasion, a proportion of the animals developed recurrent disease, with the exception of Balb/c mice. The different reaction of Balb/c and other inbred strains might prove useful in studies on the mechanism of control of recurrent herpes simplex.

    Full Text Available Acute renal failure (ARF is a rare complication of acute pyelonephritis in adult immunocompetent patients. Recovery of renal function usually occurs if antibiotics are promptly initiated. However, long-term consequences of renal scarring due to acute pyelonephritis are probably underestimated, and some patients present with prolonged renal failure despite adequate antibiotic therapy. We report two cases of severe ARF complicating bacterial pyelonephritis successfully treated with corticosteroids in association with conventional antibiotics.

    Tungiasis (sand flea disease) is a neglected tropical disease. Heavy infestation results in mutilation of the feet and difficulty in walking. We identified eight individuals with extremely severe tungiasis in rural Madagascar. To prevent reinfestation, four individuals received solid shoes and four received a daily application of an herbal repellent effective against Tunga penetrans. Over a period of 10 weeks the feet were examined and the severity of tungiasis-associated morbidity was measured. Within this period, the severity score for acute tungiasis decreased 41% in the shoe group and 89% in the repellent group. The four major inflammation-related symptoms disappeared in the four patients of the repellent group, but only in two patients of the shoe group. Those observations indicate that cases with extremely severe tungiasis, associated morbidity almost totally disappears within 10 weeks if the feet are protected by a repellent. Wearing shoes reduced acute morbidity only marginally.

    Conclusion: While the respiratory complaint was perceived as being the most detrimental of all presenting complaints, there was an overall non-threatening outcome in all patients. The presenting respiratory complaints were mostly subjective with benign outcome. Although various risk factors associated with severity increase of respiratory status, were present in a few of the index cases patients, their affect was negligible with a resultant benign outcome.

    Acute severe pancreatitis caused high mortality, and several scoring systems for predicting mortality are available. We evaluated the effectiveness of serial measurement of several scoring systems in patients with acute severe pancreatitis.We retrospectively obtained serial measurements of Ranson, Acute Physiology and Chronic Health Assessment (APACHE) II, and Sequential Organ Failure Assessment (SOFA) scores of 159 patients with acute severe pancreatitis.The overall mortality rate was 20%, and early mortality (in the first 2 weeks) occurred in 10 (7.4%) patients, while late mortality occurred in 17 (12.6%).All scoring systems were reliable for predicting overall and intensive care unit mortality, while the SOFA score on day 7 presented the largest area under the receiver operator characteristic (ROC) curve (0.858, SE 0.055). Changes in scores over time were evaluated for predicting the progression of organ failure, and the change in SOFA score on hospital day 7 or no interval change in SOFA score was associated with higher mortality rates.APACHE II and SOFA scores are both sensitive for predicting mortality in acute pancreatitis. The serial SOFA scores showed reliable for predicting mortality. Hospital day 7 is a reasonable time for SOFA score reassessment to predict late mortality in acute severe pancreatitis.

    Severe acute pancreatitis may be complicated by intra-abdominal hypertension (IAH), abdominal compartment syndrome (ACS), and intestinal ischemia. The aim of this retrospective study is to describe the incidence, treatment, and outcome of patients with severe acute pancreatitis and ACS, in particular the occurrence of intestinal ischemia. The medical records of all patients admitted with severe acute pancreatitis admitted to the ICU of a tertiary referral center were reviewed. The criteria proposed by the World Society of the Abdominal Compartment Syndrome (WSACS) were used to determine whether patients had IAH or ACS. Fifty-nine patients with severe acute pancreatitis were identified. Intra-abdominal pressure (IAP) measurements were performed in 29 patients (49.2 %). IAH was present in all patients (29/29). ACS developed in 13/29 (44.8 %) patients. Ten patients with ACS underwent decompressive laparotomy. A large proportion of patients with ACS had intra-abdominal ischemia upon laparotomy: 8/13 (61.5 %). Mortality was high in both the ACS group and the IAH group. This study confirms that ACS is common in severe acute pancreatitis. Intra-abdominal ischemia occurs in a large proportion of patients with ACS. Swift surgical intervention may be indicated when conservative measures fail in patients with ACS. National and international guidelines need to be updated so that routine IAP measurements become standard of care for patients with severe acute pancreatitis in the ICU.

    Objective: To study MRI findings of abdominal wall edema (AWE) in acute pancreatitis as well as correlations between AWE and the severity of acute pancreatitis according to the MR severity index (MRSI) and the Acute Physiology And Chronic Healthy Evaluation III (APACHE III) scoring system. Materials and methods: A total of 160 patients with AP admitted to our institution between December 2009 and March 2011 were included in this study. MRI was performed within 48 h after admission. MRI findings of acute pancreatitis were noted, including AWE on the MRI. The abdominal wall area was divided into quarters, and each area involved was recorded as 1 point to score the severity of AWE. The severity of acute pancreatitis was studied using both the MRSI and the APACHE III scoring system. Spearman correlation of AWE with the MRSI and the APACHE III scoring system was analyzed. Results: In 160 patients with acute pancreatitis, 53.8% had AWE on MRI. The average AWE score was 1.2 {+-} 1.4 points. The prevalence of AWE was 30.5%, 64.5% and 100% in mild, moderate and severe AP, respectively, according to MRSI. AWE on MRI was correlated with MRSI scores (r = 0.441, p = 0.000). According to APACHE III scores, the averages were 2.0 {+-} 1.1 and 2.6 {+-} 1.1 points in mild AP and severe AP, respectively (P = 0.016). AWE was slightly correlated with the APACHE III scores (r = 0.222, p = 0.005). Conclusion: AWE on MRI in acute pancreatitis is common, which may be a supplementary indicator in determining the severity of AP.

    Pathogenesis of severe acute pancreatitis is still unclear, which leads to a lack of proper treatment in severe acute pancreatitis therapeutic strategy. To investigate the effect of treatment with antioxidant pyrrolidine dithiocarbamate on pancreas injury in rats with severe acute pancreatitis and its possible mechanism. A total of 144 male Sprague-Dawley rats were randomly allocated into a sham operation group (n=48), a severe acute pancreatitis group (n=48), and a pyrrolidine dithiocarbamate-treated group (n=48). All the rats were killed at 1, 3, 6, 12, 24, and 48 h after operation. The pancreas histopathologies were observed and serum amylase levels were tested. Meanwhile, the nuclear factor-kappaB activation, tumor necrosis factor-alpha levels and high-mobility group box protein-1 expression levels in pancreatic tissue were studied. Animals receiving pyrrolidine dithiocarbamate had significantly improved pancreas histopathology and lower serum amylase levels (pacute pancreatitis group, pancreas tumor necrosis factor-alpha levels reached a peak at 6 h after operation and afterwards rapidly declined to normal levels. However, high-mobility group box protein-1 levels in pancreatic tissue increased remarkably at the 12th hour, reached a peak at 24 h, and maintained up to 48 h post-severe acute pancreatitis. Compared to the severe acute pancreatitis group, the pancreas nuclear factor-kappaB activity, tumor necrosis factor-alpha, high-mobility group box protein-1 levels in the pyrrolidine dithiocarbamate-treated group all remarkably decreased (pacute pancreatitis. Pyrrolidine dithiocarbamate might inhibit the activation of nuclear factor-kappaB to blockade tumor necrosis factor-alpha, thereby indirectly suppressing the high-mobility group box protein-1 and reducing pancreatic tissue damage in rats with severe acute pancreatitis.

    Full Text Available Background/Aims. At present, there is no simple test for predicting severity in acute pancreatitis. We investigated the use of an assay of soluble E-cadherin (sE-cadherin. Methods. Concentrations of sE-cadherin, from 19 patients with mild acute pancreatitis, 7 patients with severe acute pancreatitis, 11 patients with other acute gastrointestinal pathologies, and 12 healthy subjects were measured using a commercially available sandwich ELISA kit based on two monoclonal antibodies specific to the extracellular fragment of human E-cadherin. Measurements were made at 12 hours or less from onset of pain and also at 24 and 48 hours after onset of pain. Results. Mean (standard deviation concentration of sE-cadherin in patients with severe acute pancreatitis at <12 hours was 17780 ng/mL (7853, significantly higher than that of healthy volunteers 5180 ng/mL (1350, =.0039, patients with other gastrointestinal pathologies 7358 ng/mL (6655, =.0073, and also significantly higher than that of patients with mild pancreatitis, 7332 ng/mL (2843, =.0019. Discussion. Serum sE-cadherin could be an early (within 12 hours objective marker of severity in acute pancreatitis. This molecule warrants further investigation in the form of a large multicentre trial.

    Curcuma longa (turmeric) has a long history of use in Ayurvedic medicine as a treatment for inflammatory conditions. The purpose of the present study was to investigate the preventive effects of curcumin against acute pancreatitis (AP) induced by caerulein in mouse and to elucidate possible mechanism of curcumin action. Curcumin (50 mg/kg/day) was intraperitoneally injected to Kun Ming male mice for 6 days, followed by injection of caerulein to induce AP. GW9662 (0.3 mg/kg), a specific peroxisome proliferator-activated receptor gamma (PPARγ) antagonist, was intravenously injected along with curcumin. Murine macrophage RAW264.7 cells were treated with 100 μmol/l curcumin for 2 h, and then stimulated with 0.1 μ g/ml lipopolysaccharide (LPS). Serum amylase and transaminase levels were measured at 10 h after AP. TNF-α level in mouse serum and cell culture medium were detected by ELISA. Expression of PPARγ and NF-κB were analyzed by RT-PCR and Western blot. Curcumin significantly decreased the pancreas injury and reversed the elevation of serum amylase, ALT and AST activities and TNF-α level in mice with AP. Curcumin treatment inhibited the elevation of NF-κB-p65 in the nucleus of mouse pancreas AP group and RAW264.7 cells, but significantly increased the expression of PPARγ. GW9662 could abolish the effects of curcumin on serum levels of amylase, ALT, AST, TNF-α, and NF-κB level. Our results suggest that curcumin could attenuate pancreas tissue and other organ injury by inhibiting the release of inflammatory cytokine TNF-α. These effects may involve upregulation of PPARγ and subsequent downregulation of NF-κB.

    In the management of mild acute biliary pancreatitis, it is generally recommended to perform laparoscopic cholecystectomy after the subsidence of the attack during the same hospital admission. The effect of laparoscopy on abdominal organs has been widely investigated but not in acute pancreatitis. This study used an animal model of mild acute pancreatitis to examine the effects of CO(2) pneumoperitoneum on acute pancreatitis in rats. Mild acute pancreatitis was induced in 30 male Sprague-Dawley rats by surgical ligation of the biliopancreatic duct. After 2 days, animals were assigned to three groups: sham operation (animals were anesthetized for 30 min without undergoing laparotomy), CO(2) pneumoperitoneum (applied for 30 min at a pressure of 12 mmHg), and laparotomy (performed for 30 min, and then the abdomen was closed). Two hours after the surgical procedures, animals were killed and levels of lactate dehydrogenase, aspartate aminotransferase, glucose, urea, hematocrit, and leukocyte count among Ranson's criteria and levels of amylase, lipase, and total bilirubin were measured to determine the severity of acute pancreatitis. Histopathologic examination of the pancreas was done, and malondialdehyde and glutathione levels of the pancreas and lung were determined. The only significant differences between the groups were in lactate dehydrogenase and aspartate aminotransferase levels, which were significantly higher in the pneumoperitoneum group compared to the sham operation group. CO(2) pneumoperitoneum for 30 min at a pressure of 12 mmHg did not affect the severity of acute pancreatitis induced by ligation of the biliopancreatic duct in rats.

    Methaemoglobin is a form of haemoglobin in which the ferrous (Fe 2+ ) ion contained in the iron-porphyrin complex of haem is oxidised to its ferric (Fe 3+ ) state. Methaemoglobinaemia, the presence of methaemoglobin in the blood, is most commonly treated with methylene blue. However, methylene blue cannot be used in patients with glucose-6-phosphate dehydrogenase (G6PD) deficiency as it is ineffective in such patients and it can worsen G6PD deficiency haemolysis. We report the case of a 30-year-old man who presented with clinical features of G6PD deficiency-associated haemolysis and was found to have severe methaemoglobinaemia (35%). He was administered blood transfusions and intravenous ascorbic acid. His methaemoglobinaemia resolved within 24 hours. This case demonstrates the successful management of a patient with severe methaemoglobinaemia in the setting of G6PD deficiency haemolysis. Emergency physicians should be aware of the possible co-occurrence of severe methaemoglobinaemia in a patient with G6PD deficiency haemolysis. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2018.

    Acute severe mitral regurgitation (MR) is a serious medical condition. Whilst clear guidelines exist regarding the management of chronic MR, acute severe MR is usually treated on an individual basis. Currently, few data exist regarding acute MR in the era of primary coronary interventions (PCI). The present study included patients admitted to the Department of Cardiology during recent years with acute severe MR of different etiologies, and an analysis of these data in the light of previous investigations. The digital database of the present authors' hospital was searched for patients diagnosed with severe MR between 2008 and 2015. From a total of 228 patients identified, 19 with primary MR and 17 with secondary (functional) MR were admitted to the Department of Cardiology. The clinical data and outcome of these patients were analyzed. Among patients with MR due to acute myocardial infarction (MI), 13 had functional MR and six had MR due to mechanical complications, namely rupture of the papillary muscle or chordae tendineae. Among patients with MR not in the setting of MI, 13 had primary MR and four had functional MR. Patients with MR due to acute MI were more often in cardiogenic shock or had pulmonary edema and had a higher mortality. The strongest predictor of mortality was the presence of shock, followed by female gender, hypertension, age ≥68 years; previous MI and pulmonary edema were also predictors of mortality. In patients with acute MI and secondary MR, PCI to the culprit coronary artery was associated with a lesser degree of MR on follow up. Patients with severe MR are at high risk of in-hospital death. Patients with functional MR are likely to benefit from prompt PCI to the culprit artery, and for those with primary MR urgent surgery is life-saving.

    Acute infarct volume, often proposed as a biomarker for evaluating novel interventions for acute ischemic stroke, correlates only moderately with traditional clinical end points, such as the modified Rankin Scale. We hypothesized that the topography of acute stroke lesions on diffusion-weighted magnetic resonance imaging may provide further information with regard to presenting stroke severity and long-term functional outcomes. Data from a prospective stroke repository were limited to acute ischemic stroke subjects with magnetic resonance imaging completed within 48 hours from last known well, admission NIH Stroke Scale (NIHSS), and 3-to-6 months modified Rankin Scale scores. Using voxel-based lesion symptom mapping techniques, including age, sex, and diffusion-weighted magnetic resonance imaging lesion volume as covariates, statistical maps were calculated to determine the significance of lesion location for clinical outcome and admission stroke severity. Four hundred ninety subjects were analyzed. Acute stroke lesions in the left hemisphere were associated with more severe NIHSS at admission and poor modified Rankin Scale at 3 to 6 months. Specifically, injury to white matter (corona radiata, internal and external capsules, superior longitudinal fasciculus, and uncinate fasciculus), postcentral gyrus, putamen, and operculum were implicated in poor modified Rankin Scale. More severe NIHSS involved these regions, as well as the amygdala, caudate, pallidum, inferior frontal gyrus, insula, and precentral gyrus. Acute lesion topography provides important insights into anatomic correlates of admission stroke severity and poststroke outcomes. Future models that account for infarct location in addition to diffusion-weighted magnetic resonance imaging volume may improve stroke outcome prediction and identify patients likely to benefit from aggressive acute intervention and personalized rehabilitation strategies. © 2015 American Heart Association, Inc.

    Acute diarrheal illness constitutes a major cause of morbidity and mortality in children in developing countries. Most of the complications of diarrhea occur due to excessive fluid and electrolyte loss; adverse complications are seen more with increasing severity of dehydration. This study was conducted to identify the relation of renal function and electrolyte abnormalities in children with varying severity of dehydration. This study was carried out in Manipal Teaching Hospital, Pokhara, Nepal over duration of one year. The aims were to find out the association of renal function and electrolyte disturbances with type of diarrhea, severity of dehydration and their relation to outcome. All children more than one month and less than 15 years with acute diarrhea were included in the study. Data were entered and analyzed by SPSS version 19. Statistical analysis applied was Chi-square test. A p-value of Dehydration was associated more with Acute Watery Diarrhea than with Invasive Diarrhea. Renal function and electrolyte abnormalities were seen more in Acute Watery Diarrhea with increasing levels of blood urea, serum creatinine and abnormal levels of serum sodium seen with increased severity of dehydration. Abnormalities in renal function and electrolytes correlated significantly with severity of dehydration. The outcome of patients correlated with severity of dehydration with mortality occurring in 18.1% of patients with Severe dehydration, 0.8% of Some dehydration with no mortality in the No dehydration group.

    Rapid eye movement (REM) sleep deprivation (SD) is implicated in impairment of spatial learning and memory and hippocampal long-term potentiation (LTP). An increase in nicotine consumption among habitual smokers and initiation of tobacco use by nonsmokers was observed during SD. Although nicotine treatment was reported to attenuate the impairment of learning and memory and LTP associated with several mental disorders, the effect of nicotine on SD-induced learning and memory impairment has not been studied. Modified multiple platform paradigm was used to induce SD for 24 or 48 h during which rats were injected with saline or nicotine (1 mg kg(-1) s.c.) twice a day. In the radial arm water maze (RAWM) task, 24- or 48-h SD significantly impaired learning and short-term memory. In addition, extracellular recordings from CA1 and dentate gyrus (DG) regions of the hippocampus in urethane anesthetized rats showed a significant impairment of LTP after 24- and 48-h SD. Treatment of normal rats with nicotine for 24 or 48 h did not enhance spatial learning and memory or affect magnitude of LTP in the CA1 and DG regions. However, concurrent, acute treatment of rats with nicotine significantly attenuated SD-induced impairment of learning and STM and prevented SD-induced impairment of LTP in the CA1 and DG regions. These results show that acute nicotine treatment prevented the deleterious effect of sleep loss on cognitive abilities and synaptic plasticity. Copyright © 2010 Wiley-Liss, Inc.

    CT findings in 28 patients with acute pancreatitis were compared with severity of the disease. The pancreatic image, which demonstrates the pancreatic lesion, was studied with respect to 9 items, and fluid collection showing the peripancreatic status with respect to 13 items. 1) According to Forell's classification, the lesion was minor in 8 patients, moderate in 11, and severe in 9. 2) The detection rates of abnormal pancreatic images and fluid collection increased with the advance in the severity of the disease. 3) The mean CT score by severity was 0.88 ± 0.64 for minor pancreatitis, 7.18 ± 4.51 for moderate pancreatitis, and 13.44 ± 4.22 for severe pancreatitis. Significant differences were observed among the groups, suggesting the usefulness of the CT score in evaluating the severity of acute pancreatitis. (author)

    Early recognition of severe form of acute pancreatitis is important because these patients need more agressive diagnostic and therapeutical approach an can develope systemic complications such as: sepsis, coagulopathy, Acute Lung Injury (ALI), Acute Respiratory Distress Syndrome (ARDS), Multiple Organ Dysfunction Syndrome (MODS), Multiple Organ Failure (MOF). To determine role of the combination of Systemic Inflammatory Response Syndrome (SIRS) score and serum Interleukin-6 (IL-6) level on admission as predictor of illness severity and outcome of Severe Acute Pancreatitis (SAP). We evaluated 234 patients with first onset of SAP appears in last twenty four hours. A total of 77 (33%) patients died. SIRS score and serum IL-6 concentration were measured in first hour after admission. In 105 patients with SIRS score 3 and higher, initial measured IL-6 levels were significantly higher than in the group of remaining 129 patients (72 +/- 67 pg/mL, vs 18 +/- 15 pg/mL). All nonsurvivals were in the first group, with SIRS score 3 and 4 and initial IL-6 concentration 113 +/- 27 pg/mL. The values of C-reactive Protein (CRP) measured after 48h, Acute Physiology and Chronic Health Evaluation (APACHE II) score on admission and Ranson score showed the similar correlation, but serum amylase level did not correlate significantly with Ranson score, IL-6 concentration and APACHE II score. The combination of SIRS score on admission and IL-6 serum concentration can be early, predictor of illness severity and outcome in SAP.

    Objective: To study the correlation between the manifestations of the posterior pararenal space (PPS) involvement and the clinical severity, CT severity index (CTSI) of acute pancreatitis (AP), and to ascertain the value of PPS involvement in assessing the severity of AP. Methods: The CT images of 87 cases in AP were retrospectively observed. Clinical severity, CTSI, and CT grading of the PPS involvement of AP were assessed and scored, respectively. Results: CT morphologic and craniocaudal extent grading of the PPS abnormalities had positive correlation with clinical severity grading and CTSI of AP (P<0.05). CT morphologic grading of the PPS also had positive correlation with its craniocaudal extent CT grading (P<0.05). For predicting the severity of AP, the abnormalities of the PPS had sensitivity of 60.3%, specificity of 87.5%, positive predictive value of 92.7%, negative predictive value of 45.7%, and accuracy of 67.8%. Conclusion: PPS involvement and it's severity in AP could reflect the severity of AP to some extent, and may be helpful for initial excluding mild AP. (authors)

    Macrophages are crucially involved in the pathophysiology of acute pancreatitis. Soluble CD163 (sCD163) is specifically released from macrophages and systemic levels are increased in inflammatory diseases. Here, sCD163 was measured in serum of 50 patients with acute pancreatitis to find out possible associations with disease activity. Admission levels of systemic sCD163 were nearly three-fold higher in patients with acute pancreatitis compared to controls. In patients sCD163 did not correlate with C-reactive protein and leukocyte count as established markers of inflammation. Levels were not associated with disease severity assessed by the Schroeder score, Balthazar score, Acute Physiology, Age, and Chronic Health Evaluation (Apache) II score and peripancreatic necrosis score. Soluble CD163 was not related to complications of acute pancreatitis. These data show that serum sCD163 is increased in acute pancreatitis indicating activation of macrophages but is not associated with disease severity and outcome. Copyright © 2015 Elsevier Inc.

    The severity of acute radiation injury to small bowel mucosa in rats was studied as a function of lumenal pH at the time of irradiation. Indices of injury were surviving crypt numbers, mucosal height and mucous-containing goblet cells. Animals were sacrificed 5 days postirradiation. For all three parameters and on each day postirradiation, the pH 9 segment showed less damage than segments with lumenal pH 7 or 5. The authors conclude that lumenal pH at the time of irradiation plays a significant role in the severity of acute mucosal injury. Alkaline pH is relatively protective. (author)

    Full Text Available Abstract Background Scrub typhus is an acute febrile illness caused by Orientia tsutsugamushi. Case presentations We encountered a patient with sensorineural hearing loss complicating scrub typhus, and three patients with scrub typhus who complained of otalgia, which was sudden onset, severe, paroxysmal, intermittent yet persistent pain lasting for several seconds, appeared within 1 week after the onset of fever and rash. The acute sensorineural hearing loss and otalgia were resolved after antibiotic administration. Conclusion When patients in endemic areas present with fever and rash and have sensorineural hearing loss or otalgia without otoscopic abnormalities, clinicians should suspect scrub typhus and consider empirical antibiotic therapy.

    Resectional procedures for advanced and complicated appendicitis are performed infrequently. Their extent can vary: cecal resection, ileocecectomy, and even right hemicolectomy. We present a very rare case of appendectomy that was combined with partial ileal resection for severe necrotic changes and small perforation of the ileum. A 19-year-old female patient was hospitalized with right iliac fossa pain and fever 10 days after the onset of symptoms. On laparoscopy, a large mass in a right iliac fossa was found. The ultrasound-guided drainage of the suspected appendiceal abscess was unavailable. After conversion using McBurney's incision, acute perforated appendicitis was diagnosed. It was characterized by extension of severe necrotic changes onto the ileal wall and complicated by right iliac fossa abscess. A mass was bluntly divided, and a large amount of pus with fecaliths was discharged and evacuated. Removal of necrotic tissues from the ileal wall led to the appearance of a small defect in the bowel. A standard closure of this defect was considered as very unsafe due to a high risk of suture leakage or bowel stenosis. We perform a resection of the involved ileum combined with appendectomy and drainage/tamponade of an abscess cavity. Postoperative recovery was uneventful. The patient was discharged on the 15th day. In advanced appendicitis, the involved bowel resection can prevent possible complications (e.g., ileus, intestinal fistula, peritonitis, and intra-abdominal abscess). Our case may be the first report of an appendectomy combined with an ileal resection for advanced and complicated appendicitis.

    Full Text Available Objective To study the prophylactic effect of zolpidem on acute mountain sickness (AMS after acute high-altitude exposure. Methods A randomized double-blind placebo controlled trial was performed on the plateau. Forty subjects were randomly divided into zolpidem group and placebo group. The general clinical data, heart rate, blood pressure, oxygen saturation, the Pittsburgh Sleep Quality Index (PSQI scores, AMS scores and physical fitness test of the both groups were collected and assessed on plain and plateau, respectively. Results The PSQI scores were obviously lower and the six-minute walk distance was significantly longer in zolpidem group than those in placebo group (P=0.047 and P=0.009, respectively after acute high-altitude exposure. AMS incidence was significantly lower in zolpidem group than in placebo group at different time points (P=0.019, 0.014, 0.025 and 0.026, respectively, and the incidence of severe AMS was also significantly lower in zolpidem group than in placebo group at different time points (P=0.047, 0.044, 0.031 and 0.020, respectively. The symptoms of dizziness, weakness and fatigue were significantly lighter in zolpidem group than in placebo group after acute exposure to high-altitude exposure for 20 hours (P0.05. Conclusion Zolpidem may alleviate AMS symptoms and reduce the incidence of AMS, so it may be promising as a new choice for the prevention of AMS. DOI: 10.11855/j.issn.0577-7402.2015.09.09

    Experimental aristolochic acid nephropathy is characterized by early tubulointerstitial injury followed by fibrosis, reproducing chronic lesions seen in humans. In vitro, probenecid inhibits aristolochic acid entry through organic anion transporters, reduces specific aristolochic acid-DNA adduct formation, and preserves cellular viability. To test this in vivo, we used a mouse model of aristolochic acid nephropathy displaying severe tubulointerstitial injuries consisting of proximal tubular epithelial cell necrosis associated to transient acute kidney injury followed by mononuclear cell infiltration, tubular atrophy, and interstitial fibrosis. Treatment with probenecid prevented increased plasma creatinine and tubulointerstitial injuries, and reduced both the extent and the severity of ultrastructural lesions induced by aristolochic acid, such as the loss of brush border, mitochondrial edema, and the disappearance of mitochondrial crests. Further, the number of proliferating cell nuclear antigen-positive cells and total aristolochic acid-DNA adducts were significantly reduced in mice receiving aristolochic acid plus probenecid compared with mice treated with aristolochic acid alone. Thus, we establish the nephroprotective effect of probenecid, an inhibitor of organic acid transporters, in vivo toward acute proximal tubular epithelial cell toxicity in a mouse model of aristolochic acid nephropathy.

    To analyze the clinical features of acute intra-operative encephalocele and the proper prophylactic-therapeutic measures for severe craniocerebral injury. The clinical data were collected and analyzed for 21 patients with severe head injuries who suffered acute intra-operative encephalocele from June 2008 to May 2010. There were 12 males and 9 females with an age range of 18 - 69 years old. Among these patients, 6 died with a mortality rate of 28.5%. It was lower than that reported in literatures. One patient died post-operatively of severe brain swelling and intracranial infection secondary to leakage of cerebrospinal fluid. Four patients died of severe craniocerebral injury, brain swelling and brain stem failure. And 1 patient died after his guardian abandoned the treatment. The follow-up period for the remaining 15 surviving patients was 3 - 6 months. According to the Glasgow outcome score (GOS), there were a favorable prognosis (n = 9), moderate disabilities (n = 5) and severe disability (n = 1). The probability of acute intra-operative encephalocele may be predicted in advance with a combination of clinical features and computed tomographic scans. The therapeutic success rate of acute encephalocele will be boosted by taking protective and therapeutic measures pre- and intra-operatively.

    To assess the benefits of pancreatic enzyme replacement therapy (PERT) in children with complicated severe acute malnutrition. We conducted a randomized, controlled trial in 90 children aged 6-60 months with complicated severe acute malnutrition at the Queen Elizabeth Central Hospital in Malawi. All children received standard care; the intervention group also received PERT for 28 days. Children treated with PERT for 28 days did not gain more weight than controls (13.7 ± 9.0% in controls vs 15.3 ± 11.3% in PERT; P = .56). Exocrine pancreatic insufficiency was present in 83.1% of patients on admission and fecal elastase-1 levels increased during hospitalization mostly seen in children with nonedematous severe acute malnutrition (P pancreatic enzymes (18.6% vs 37.8%; P pancreatic insufficiency was not improved by PERT, but children receiving PERT were more likely to be discharged with every passing day (P = .02) compared with controls. PERT does not improve weight gain in severely malnourished children but does increase the rate of hospital discharge. Mortality was lower in patients on PERT, a finding that needs to be investigated in a larger cohort with stratification for edematous and nonedematous malnutrition. Mortality in severe acute malnutrition is associated with markers of poor digestive function. ISRCTN.com: 57423639. Copyright © 2017 Elsevier Inc. All rights reserved.

    Although Plasmodium ovale is considered the cause of only mild malaria, a case of severe malaria due to P. ovale with acute respiratory distress syndrome is reported. A 37-year old Caucasian man returning home from Angola was admitted for ovale malaria to the National Institute for Infectious Diseases Lazzaro Spallanzani in Rome, Italy. Two days after initiation of oral chloroquine treatment, an acute respiratory distress syndrome was diagnosed through chest X-ray and chest CT scan with intravenous contrast. Intravenous artesunate and oral doxycycline were started and he made a full recovery. Ovale malaria is usually considered a tropical infectious disease associated with low morbidity and mortality. However, severe disease and death have occasionally been reported. In this case clinical failure of oral chloroquine treatment with clinical progression towards acute respiratory distress syndrome is described.

    Acute graft-versus-host disease is a major problem in allogeneic bone-marrow transplantation. We performed a randomized study to compare the effectiveness of two regimens in the prevention of acute graft-versus-host disease. Thirty-five patients received methotrexate alone, and 32 received methotrexate, antithymocyte globulin, and prednisone. Of the patients who received methotrexate alone, 48 percent had acute graft-versus-host disease, as compared with 21 per cent of those who received methotrexate, antithymocyte globulin, and prednisone (P = 0.01). The age of the recipient was a significant factor in the development of acute graft-versus-host disease: Older patients had a higher incidence of the disease (P = 0.001). We conclude that the combination of methotrexate, antithymocyte globulin, and prednisone significantly decreased the incidence of acute graft-versus-host disease and should be used to prevent this disorder in patients receiving allogeneic marrow transplants

    Background/Aims Acute complicated diverticulitis can be subdivided into moderate diverticulitis and severe diverticulitis. Although there have been numerous studies on the risk factors for complicated diverticulitis, little research has focused on severe diverticulitis. This study was designed to identify the risk factors for severe diverticulitis in an acute diverticulitis attack using the modified Hinchey classification. Methods Patients were included if they had any evidence of acute diverticulitis detected by computed tomography. The patients were subdivided into severe diverticulitis (Hinchey class ≥Ib; abscesses or peritonitis) and moderate diverticulitis (Hinchey class Ia; pericolic inflammation) groups. Results Of the 128 patients, 25 exhibited severe diverticulitis, and 103 exhibited moderate diverticulitis. In a multivariate analysis, age >50 years (odds ratio [OR], 5.27; p=0.017), smoking (OR, 3.61; p=0.044), comorbidity (OR, 4.98; p=0.045), leukocytosis (OR, 7.70; p=0.003), recurrence (OR, 4.95; p=0.032), and left-sided diverticulitis (OR, 6.92; p=0.006) were significantly associated with severe diverticulitis. Conclusions This study suggests that the risk factors for severe diverticulitis are age >50 years, smoking, comorbidity, leukocytosis, recurrent episodes, and left-sided diverticulitis.

    2017-01-01

    Full Text Available Introduction: Acute pancreatitis is inflammatory process of the pancreas associated with local and systemic complications. At present, there are lots of scores (such as Ransons, APACHE II, bedside index for severity in acute pancreatitis that help us in predicting severity at the time of admission but these are time consuming or require complex calculation and are costly. Material and Methods: PANC3 Scoring System is one of the better systems because the three criteria used (hematocrit, body mass index, and pleural effusion are simple, easy to assess, readily available, and economic. In this prospective study, 100 cases were evaluated to see the prospects of PANC3 scoring in predicting the severity of acute pancreatitis as decided by modified Marshals score. Results: The results showed that PANC3 score had a 96.43% specificity, 75% sensitivity, 80% positive predictive value, and 95.29% negative predictive value. Conclusion: Hence, the PANC3 score is a cost-effective, promising score that helps in predicting the severity of acute pancreatitis leading to prompt treatment and early referral to higher center.

    1987-06-01

    We report two cases of severe acute pancreatitis; a 53-year-old man (Case 1) and a 60-year-old woman (Case 2). Case 1 was classified as ''severe'' according to the Ranson's criteria and he died of MOF on the 21st hospital day. Case 2 was classified as ''moderate'', but a large pancreatic abscess was observed by CT scan. She died of this abscess complicated with duodenal perforation on the 33rd hospital day. CT findings showed that this case was not ''moderate'' but ''severe''. Therefore, we believe that the findings of CT scan are an important factor for assessment of the severity of acute pancreatitis.

    2008-01-01

    Medical management during acute period in a case of severe local radiation injury after acute X-ray exposure includes 3 stages. During the fist stage patient got conservative treatment according to the common pathogenetic mechanisms of LRI (dis aggregating therapy, stimulation of regeneration, dis intoxication therapy, antibiotic therapy, pain relief therapy, Local anti-burn therapy-specific non-adhesive bandage with antiseptic and anti-burn medicaments); estimation of severity, deepness and area of injury by clinical picture and dates of instrumental methods of examining; defining necessity and volume of surgical treatment; preparing arrangements for surgical treatment. This stage ends with forming of demarcation line of a very hard severity of a Local Radiation Injure. The second stage includes necrectomy of the area of a very hard severity with microsurgical plastic by re vascularized flap and auto dermoplastic. The third stage - adaptation of re vascularized flap and total epithelization of injured area. (author)

  2. Acute Liver Injury with Severe Coagulopathy in Marasmus Caused by a Somatic Delusional Disorder

    Lance L. Stein

    2011-01-01

    Full Text Available Marasmus is a severe form of protein-calorie malnutrition characterized by the depletion of fat stores, muscle wasting, and the lack of edema. In developed countries, marasmus is often the result of anorexia nervosa. Abnormal transaminases with liver synthetic dysfunction have rarely been reported with anorexia nervosa. To our knowledge, we report the first detailed case of acute liver injury with severe coagulopathy (INR>1.5 in a patient with marasmus due to self-induced calorie restriction caused by a somatic delusional disorder. This case highlights the severity of liver injury that may occur with significant weight loss from self-induced calorie restriction and the rapid normalization of this injury with treatment. It is important for clinicians to be aware of patterns of acute liver injury in patients with severe protein-calorie malnutrition, regardless of the underlying cause.

  3. Lung injury in acute pancreatitis: mechanisms, prevention, and therapy.

    LENUS (Irish Health Repository)

    Shields, Conor J

    2012-02-03

    Lung injury is the most pertinent manifestation of extra-abdominal organ dysfunction in pancreatitis. The propensity of this retroperitoneal inflammatory condition to engender a diffuse and life-threatening lung injury is significant. Approximately one third of patients will develop acute lung injury and acute respiratory distress syndrome, which account for 60% of all deaths within the first week. The variability in the clinical course of pancreatitis renders it a vexing entity and makes demonstration of the efficacy of any specific intervention difficult. The distinct pathologic entity of pancreatitis-associated lung injury is reviewed with a focus on etiology and potential therapeutic maneuvers.

    Hospital stays for patients with pressure ulcers (PU) increased nearly 80% from 1992 to 2006. Most PU's developed during an admission, often despite preventive efforts from clinical staff. Data from Electronic medical records (EMR's) were used to prepare daily patient risk factor and PU information for nurses to help prevent PU development and exacerbations. THE OBJECTIVES OF THIS STUDY WERE TO DETERMINE WHETHER: 1) dissemination of an automated daily report with patient risk and current status of pressure ulcers ("PU Daily") helps prevent the development of pressure ulcers, and 2) using the PU Daily information impacts the severity of pressure ulcers that develop in an acute care setting. A pre-post study with four control units was designed to determine the impact of the PU Daily in intensive care units (ICU) in a large medical center. The control units included ICU's using the same EMR and similar complexity of cases with a high risk of developing a PU. The pre-post study took place over a six month period (March - August 2009). A total of 6,735 cases were included in the study. The intervention unit showed a significant decrease (p = 0.004) in PU's at post-evaluation; none of the four comparison units showed a decrease at the pintervention led to a significant reduction in the total number of PU's documented (p intervention with the PU Daily showed a significant decrease in the total PU's and severity of PU's and allowed for implementation of interventions that help prevent the development of PU's. As EMR's become more widely available, this intervention showed a reduction in PU's. Future studies should further develop this intervention and include multiple institutions and patient populations.

    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

    Full Text Available BACKGROUND Biochemical markers of inflammation could be useful to predict severity of stroke in acute phase. Stroke is the third cause of mortality and the first cause of disability. Recent literature have demonstrated that inflammation contributes to all phases of atherosclerosis. The results of researchers suggest that atherosclerosis is an inflammatory disease. The aim of the study is to assess the1. Level of peripheral inflammatory markers in acute ischaemic stroke and their relation to severity of acute stroke. 2. Value of inflammatory markers in predicting the short-term outcome and disability at the end of six months. MATERIALS AND METHODS This is a prospective case control study for 6 months done from September 2014 to August 2016 in 100 patients of acute ischaemic stroke within first 5 days of symptom onset in comparison >18 years of age with 50 age and sex matched controls. Blood samples for all cases and controls were sent for erythrocyte sedimentation rate, Neutrophil-to-Lymphocyte Ratio (NLR, hs-C-reactive protein, mean platelet volume, serum ferritin, serum albumin and S. gamma-glutamyl transferase at admission. RESULTS The mean values of ESR, NLR, hs-CRP in all the cases are higher when compared to the controls and are statistically significant, whereas the mean values of MPV, S. ferritin, S. albumin and GGT in cases are lower when compared to controls, but are within normal range and difference is statistically significant except ferritin. ESR, hs-CRP has significant correlation with severity of acute ischaemic stroke. The mean values of these markers increased with increase in severity. Serum albumin has significant correlation with severity of acute ischaemic stroke with mean values of these markers decreasing with increase in severity of stroke. There is no significant correlation of the inflammatory markers in present study with the short-term outcome. CONCLUSION Inflammation plays an important role in the pathogenesis of non

    To develop a new classification of acute pancreatitis severity on the basis of a sound conceptual framework, comprehensive review of the published evidence, and worldwide consultation. The Atlanta definitions of acute pancreatitis severity are ingrained in the lexicon of specialist in pancreatic diseases, but are suboptimal because these definitions are based on the empiric description of events not associated with severity. A personal invitation to contribute to the development of a new classification of acute pancreatitis severity was sent to all surgeons, gastroenterologists, internists, intensivists and radiologists currently active in the field of clinical acute pancreatitis. The invitation was not limited to members of certain associations or residents of certain countries. A global web-based survey was conducted, and a dedicated international symposium was organized to bring contributors from different disciplines together and discuss the concept and definitions. The new classification of severity is based on the actual local and systemic determinants of severity, rather than on the description of events that are non-causally associated with severity. The local determinant relates to whether there is (peri) pancreatic necrosis or not, and if present, whether it is sterile or infected. The systemic determinant relates to whether there is organ failure or not, and if present, whether it is transient or persistent. The presence of one determinant can modify the effect of another, whereby the presence of both infected (peri) pancreatic necrosis and persistent organ failure has a greater impact upon severity than either determinant alone. The derivation of a classification based on the above principles results in four categories of severity: mild, moderate, severe, and critical. This classification is the result of a consultative process among specialists in pancreatic diseases from 49 countries spanning North America, South America, Europe, Asia, Oceania and

    A four-year-old girl on maintenance therapy for acute lymphoblastic leukemia (ALL) complained of a headache and low back pain on the day she received her 21st intrathecal methotrexate (it-MTX) administration, and the next day experienced numbness and pain in her foot. This numbness gradually spread to her hand. She thereafter developed a fever and was hospitalized on day 8. After antibiotic therapy, the fever disappeared. However, her lower limbs became paralyzed, and she also developed urinary retention. On day 12, her paralysis progressed upwards, and she also developed paralysis of the upper limbs. Finally, she experienced convulsions with an impairment of consciousness. A magnetic resonance imaging study of the brain and spinal cord showed abnormal signals in the brain cortex and anterior horn. Accordingly, we diagnosed acute encephalomyelitis associated with it-MTX. High-dose intravenous immunoglobulin, steroid pulse therapy, plasma exchange, and dextromethorphan administration were initiated, while she received mechanical ventilation. Despite this intensive treatment, she suffered severe neurological damage and had to be maintained on mechanical ventilation due to persistent flaccid quadriplegia one year after the onset. When patients have symptoms of ascending paralysis during it-MTX treatment, clinicians should carefully consider the possibility of acute encephalomyelitis due to it-MTX.

    Mycoplasma pneumoniae (MP) is a common childhood pathogen associated with atypical pneumonia (AP). It is often a mild disease and seldom results in paediatric intensive care (PICU) admission. In 2003, World Health Organization (WHO) coined the word SARS (severe acute respiratory syndrome) in patients with severe acute respiratory symptoms (sars) for an outbreak of AP in Hong Kong due to a novel coronavirus. In 2012, another outbreak of coronavirus AP occurred in the Middle East. Confusing case definitions such as MERS (Middle East respiratory syndrome) and SARI (severe acute respiratory infections) were coined. This paper aims to present a case of MP with sars, ARDS, pneumonia and pleural effusion during the MERS epidemics, and review the incidence and mortality of severe AP with MP. We presented a case of MP with sars, acute respiratory distress syndrome (ARDS), pneumonia and pleural effusion during the MERS epidemics, and performed a literature review on the incidence and mortality of severe AP with MP requiring PICU care. In early 2013, an 11-year-old girl presented with sars, ARDS (acute respiratory distress syndrome), right-sided pneumonia and pleural effusion. She was treated with multiple antibiotics. Streptococcus pneumoniae was not isolated in this girl with 'typical' pneumonia by symptomatology and chest radiography, but tracheal aspirate identified MP instead. The respiratory equations are computed with PaO2 /FiO2 consistent with severe lung injury. Literature on the incidence and mortality of severe AP with MP requiring PICU care is reviewed. Six, 165 and 293 articles were found when PubMed (a service of the U.S. National Library of Medicine) was searched for the terms 'mycoplasma' and 'ICU', 'mycoplasma' and 'mortality', and 'mycoplasma' and 'severe'. Mortality and PICU admission associated with MP is general low and rarely reported. Experimental and clinical studies have suggested that the pathogenesis of lung injuries in MP infection is associated

    Acute bronchiolitis frequently causes infant hospitalization. Studies on different viruses or viral genomic load and disease severity or treatment effect have had conflicting results. We aimed to investigate whether the presence or concentration of individual or multiple viruses were associated with disease severity in acute bronchiolitis and to evaluate whether detected viruses modified the response to inhaled racemic adrenaline. Nasopharyngeal aspirates were collected from 363 infants with acute bronchiolitis in a randomized, controlled trial that compared inhaled racemic adrenaline versus saline. Virus genome was identified and quantified by polymerase chain reaction analyses. Severity was assessed on the basis of the length of stay and the use of supportive care. Respiratory syncytial virus (83%) and human rhinovirus (34%) were most commonly detected. Seven other viruses were present in 8%-15% of the patients. Two or more viruses (maximum, 7) were detected in 61% of the infants. Virus type or coinfection was not associated with disease severity. A high genomic load of respiratory syncytial virus was associated with a longer length of stay and with an increased frequency of oxygen and ventilatory support use. Treatment effect of inhaled adrenaline was not modified by virus type, load or coinfection. In infants hospitalized with acute bronchiolitis, disease severity was not associated with specific viruses or the total number of viruses detected. A high RSV genomic load was associated with more-severe disease. NCT00817466 and EudraCT 2009-012667-34. © The Author 2015.

    Glycoprotein 2 (GP2), the pancreatic major zymogen granule membrane glycoprotein, was reported to be elevated in acute pancreatitis in animal models. Enzyme-linked immunosorbent assays (ELISAs) were developed to evaluate human glycoprotein 2 isoform alpha (GP2a) and total GP2 (GP2t) as specific markers for acute pancreatitis in sera of 153 patients with acute pancreatitis, 26 with chronic pancreatitis, 125 with pancreatic neoplasms, 324 with non-pancreatic neoplasms, 109 patients with liver/biliary disease, 67 with gastrointestinal disease, and 101 healthy subjects. GP2a and GP2t levels were correlated with procalcitonin and C-reactive protein in 152 and 146 follow-up samples of acute pancreatitis patients, respectively. The GP2a ELISA revealed a significantly higher assay accuracy in contrast to the GP2t assay (sensitivity ≤3 disease days: 91.7%, specificity: 96.7%, positive likelihood ratio [LR+]: 24.6, LR-: 0.09). GP2a and GP2t levels as well as prevalences were significantly elevated in early acute pancreatitis (≤3 disease days) compared to all control cohorts (ppancreatitis at admission compared with mild cases (ppancreatitis with lethal outcome was 7.8 on admission (p=0.0222). GP2a and GP2t levels were significantly correlated with procalcitonin [Spearman's rank coefficient of correlation (ρ)=0.21, 0.26; p=0.0110, 0.0012; respectively] and C-reactive protein (ρ=0.37, 0.40; ppancreatitis and analysis of GP2a can aid in the differential diagnosis of acute upper abdominal pain and prognosis of severe acute pancreatitis.

    Background and Aims Clinical manifestations of hepatitis A virus (HAV) infection vary from mild to fulminant hepatic failure (FHF) in adults. We investigated the relationship between laboratory findings, including viral load, and clinical outcomes in patients with acute hepatitis A (AHA) and evaluated predictive factors for severe acute hepatitis (s-AH). Methods We analyzed the clinical manifestations of AHA in 770 patients. Patients with a prothrombin time (PT) of less than 40% of normal were classified as s-AH and included 4 patients with FHF, 11 patients with acute renal failure, and 3 patients with prolonged jaundice (n = 128). Other patients were defined as mild acute hepatitis (m-AH) (n = 642). Serum samples were obtained from 48 patients with acute hepatitis A. Among them, 20 with s-AH, and 28 with m-AH, were tested for HAV RNA titer. Results In a multivariate analysis, age (HR = 1.042, P = 0.041), peak creatinine (HR = 4.014, P = 0.001), bilirubin (HR = 1.153, P = 0.003), alanine aminotransferase (ALT) (HR = 1.001, Phepatitis A.

    Describe clinical characteristics and outcomes associated with canine patients undergoing surgical intervention for treatment of acute pancreatitis. Retrospective outcome study from 2001 to 2007. Thirty-seven dogs. None. The following data were collected for dogs who underwent surgical intervention in the course of treatment for severe acute pancreatitis: preoperative clinicopathologic and physical data, ultrasonographic findings, surgical procedure detail, histopathologic findings, and transfusion requirements. The survival rate was 80.8% in dogs with extrahepatic biliary obstruction, 64.3% in dogs undergoing necrosectomy, and 40.6% with pancreatic abscess. Overall survival was 63.6%. Surgical complications included intraoperative and postoperative hemorrhage in 12 dogs, postoperative development of diabetes mellitus in 3 dogs, exocrine pancreatic insufficiency in 1 dog, and bacterial peritonitis in 2 dogs. Surgical intervention and aggressive postoperative care may be pursued in select dogs with severe acute pancreatitis. In dogs with extrahepatic biliary obstruction secondary to acute pancreatitis, surgical intervention may be associated with a good prognosis whereas dogs with pancreatic abscess formation may have a more guarded prognosis.

    Critically ill cancer patients are at increased risk for acute kidney injury, but studies on these patients are scarce and were all single centered conducted in specialized intensive care units. The objective was to evaluate the characteristics and outcomes in a prospective cohort of cancer patients admitted to several intensive care units with acute kidney injury. Prospective multicenter cohort study conducted in intensive care units from 28 hospitals in Brazil over a two-month period. Univariate and multivariate logistic regression were used to identify factors associated with hospital mortality. Out of all 717 intensive care unit admissions, 87 (12%) had acute kidney injury and 36% of them received renal replacement therapy. Kidney injury developed more frequently in patients with hematological malignancies than in patients with solid tumors (26% vs. 11%, P=0.003). Ischemia/shock (76%) and sepsis (67%) were the main contributing factor for and kidney injury was multifactorial in 79% of the patients. Hospital mortality was 71%. General and renal-specific severity-of-illness scores were inaccurate in predicting outcomes for these patients. In a multivariate analysis, length of hospital stay prior to intensive care unit, acute organ dysfunctions, need for mechanical ventilation and a poor performance status were associated with increased mortality. Moreover, cancer-related characteristics were not associated with outcomes. The present study demonstrates that intensive care units admission and advanced life-support should be considered in selected critically ill cancer patients with kidney injury.

    To evaluate the feasibility of transjugular intrahepatic portosystemic shunt (TIPS) for severe jaundice secondary to acute Budd-Chiari syndrome (BCS). From February 2009 to March 2013, 37 patients with severe jaundice secondary to acute BCS were treated. Sixteen patients without hepatic venule, hepatic veins (HV) obstruction underwent percutaneous angioplasty of the inferior vena cava (IVC) and/or HVs. Twenty-one patients with HV occlusion underwent TIPS. Serum bilirubin, liver function, demographic data and operative data of the two groups of patients were analyzed. Twenty-one patients underwent TIPS and the technical success rate was 100%, with no technical complications. Sixteen patients underwent recanalization of the IVC and/or HVs and the technical success rate was 100%. The mean procedure time for TIPS was 84.0±12.11 min and angioplasty was 44.11±5.12 min (Pjaundice in either group. Severe jaundice is not a contraindication for TIPS in patients with acute BCS and TIPS is appropriate for severe jaundice due to BCS.

    The Atlanta criteria for acute pancreatitis (AP) has been revised recently. This study was to evaluate its practical value in classification of AP, the severity assessment and management. The clinical features, severity classification, outcome and risk factors for mortality of 3212 AP patients who had been admitted in Ruijin Hospital from 2004 to 2011 were analyzed based on the revised Atlanta criteria (RAC) and the original Atlanta criteria (OAC). Compared to the OAC group, the incidence of severe acute pancreatitis (SAP) was decreased by approximately one half (13.9% vs 28.2%) in the RAC group. The RAC presented a lower sensitivity but higher specificity, and its predictive value for severity and poor outcome was higher than those of the OAC. The proportion of SAP diagnosis and ICU admission in the early phase in the RAC group was significantly lower than that in the OAC group (Pacute necrotic collection and walled-off necrosis. Compared to the OAC, the acute physiology and chronic health evaluation II (APACHE II) score, Ranson score, idiopathic etiology, respiratory failure and laparotomy debridement were not risk factors of death in contrast to walled-off necrosis. Interestingly, hypertriglyceridemia-related SAP had good outcomes in both groups. The RAC showed a higher predictive value for severity and poorer outcome than the OAC. However, the RAC resulted in fewer ICU admissions in the early phase due to its lower sensitivity for diagnosis of SAP. Among SAP cases, older age, high CTSI, renal and cardiovascular failure, complications of acute necrotic collection and walled-off necrosis were independent risk factors for mortality.

  1. How to approach the acute respiratory distress syndrome: Prevention, plan, and prudence.

    The acute respiratory distress syndrome (ARDS) is typically manifested by refractory hypoxemia with high mortality. A correct diagnosis is the first step to achieve better outcomes. An early intervention to manage modifiable risk factors of ARDS development and the avoidance of aggravating factors that increase disease severity and progression should be carefully addressed. A management plan is necessary at an early stage of ARDS to determine the level of intensive care. It should be carefully decided which therapeutic measures should be performed depending on the patient׳s underlying clinical condition. The clinician׳s considerate prudence is required in decisions of when to apply intensive measures for an ARDS treatment. Mechanical ventilator support should be carefully used depending on the patient׳s severity and pathological phase. Decreasing inappropriate alveolar strain through a low tidal volume under optimal positive end-expiratory pressure is key for ventilator support in ARDS. The extracorporeal membrane oxygenation applied in the experienced centers seems to improve the survival of patients with severe ARDS. A constellation of physical and psychological problems can develop or persist for up to 5 years in patients with ARDS. Therefore, an early mobilization with rehabilitation, even during an intensive care unit stay, should be seriously considered whenever feasible. Lastly, prevention of aspiration, stress ulcers, deep vein thrombosis, catheter-related infection, overhydration, and heavy sedation is essential to achieve better outcomes in ARDS.

    From January 2013 to January 2017, 686 consecutive patients were referred to our centre for transcatheter aortic valve replacement, including 5 subjects with severe aortic regurgitation and acute refractory cardiogenic shock. These patients were contraindicated for surgical treatment by the heart team because of high surgical risk (median logistic EuroSCORE: 74.6/Society of Thoracic Surgeons score: 37.9). The success rate of valve implantation was 100% through transfemoral access with self-expandable devices. The observed 30-day mortality rate was 20%. Hence, the transcatheter aortic valve replacement procedure might represent a successful and life-saving intervention for treatment of patients with severe aortic regurgitation who present with acute refractory cardiogenic shock.

    Full text: Background and Objectives: PDH approach utilizes local resources and solutions to rehabilitate and prevent future malnutrition in children under five. Although PDH focuses on addressing underweight, PDH includes children with MAM and may have potential to address and prevent MAM where community-based management of acute malnutrition (CMAM), specifically targeted supplementary feeding component, may not be appropriate. The objectives are: 1) to assess the effectiveness of PDH to reduce moderate and severe underweight in participant children as well as prevent malnutrition in younger siblings of participant children; and 2) to assess PDH’s effectiveness for treatment and prevention of MAM in ten villages in Burundi. Methods: Starting September to November 2012, PDH was implemented by trained community volunteers in the ten villages. A “positive deviant” inquiry identified local practices that positively impact child nutritional status. These practices were transferred to families of malnourished children through experiential learning during 12 days of “Hearth” sessions. Two weeks of home visits followed Hearth. Mid-upper arm circumference of participant children (n = 70) were measured on the first day of Hearth, with appropriate referral for cases of severe acute malnutrition. Weights of children were assessed at Day 1 (n = 94), 12 (n = 94), 30 (n = 74) and one year after the start of Hearth (n = 92). Weight gain of children at Day 12 and 30 were compared with standard weight gains for PDH (200-250 grams for Day 12 and 400 grams for Day 30). Younger siblings were also weighed at the one year follow-up (n = 73). Results: Mean weight-for-age z-scores (WAZ) of the children improved from -3.1±0.2 to -1.1±0.1 (p<0.001), showing sustained catch-up growth at home. Almost all children achieved the standard weight gain on Day 12 and Day 30 (92.6% (87/94) and 98.6% (73/74), respectively). Within one year, severe and moderate underweight decreased from 77

    SUMMARY The reason(s) that hepatitis A virus (HAV) infection may progress infrequently to acute liver failure are poorly understood. We examined host and viral factors in 29 consecutive adult patients with HAV-associated acute liver failure enrolled at 10 sites participating in the US ALF Study Group. Eighteen of twenty-four acute liver failure sera were PCR positive while six had no detectable virus. HAV genotype was determined using phylogenetic analysis and the full-length genome sequences of the HAV from a cute liver failure sera were compared to those from self-limited acute HAV cases selected from the CDC database. We found that rates of nucleotide substitution did not vary significantly between the liver failure and non-liver failure cases and there was no significant variation in amino acid sequences between the two groups. Four of 18 HAV isolates were subgenotype IB, acquired from the same study site over a 3.5-year period. Sub-genotype IB was found more frequently among acute liver failure cases compared to the non-liver failure cases (chi-square test, P liver failure within 1 month of each other. Predictors of spontaneous survival included detectable serum HAV RNA, while age, gender, HAV genotype and nucleotide substitutions were not associated with outcome. The more frequent appearance of rapid viral clearance and its association with poor outcomes in acute liver failure as well as the finding of familial cases imply a possible host genetic predisposition that contributes to a fulminant course. Recurrent cases of the rare subgenotype IB over several years at a single centre imply a community reservoir of infection and possible increased pathogenicity of certain infrequent viral genotypes.

    Renal ischemia-reperfusion predisposes to acute kidney injury (AKI) and mortality. APAC, mast cell heparin proteoglycan mimetic is a potent dual antiplatelet and anticoagulant inhibiting thrombosis in several vascular models. Clinically relevant (0.06 and 0.13 mg/kg) and high (0.32 and 7.3 mg/kg) heparin doses of APAC and unfractionated heparin (UFH) were administered i.v. in pharmacological studies. Antithrombotic action of APAC and UFH was assessed with platelet aggregation to collagen, activated partial thromboplastin (APTT) and prothrombin (PT) times. Pharmacodynamics of [ 64 Cu]-APAC or -UFH were monitored by PET/CT. Next, APAC and UFH doses (0.06 and 0.13 mg/kg) were i.v. administered 10 min prior to renal ischemia-reperfusion injury (IRI) in rats. APAC in contrast to UFH inhibited platelet aggregation. During 0.06 and 0.13 mg/kg dose regimens APTT and PT remained at baseline, but at the high APTT prolonged fourfold to sixfold. Overall bio-distribution and clearance of APAC and UFH were similar. After bilateral 30-min renal artery clamping, creatinine, urea nitrogen and neutrophil gelatinase-associated lipocalin concentrations and histopathology indicated faster renal recovery by APAC (0.13 mg/kg). APAC, unlike UFH, prevented expression of innate immune ligand hyaluronan and tubulointerstitial injury marker Kim-1. Moreover, in severe bilateral 1-h renal artery clamping, APAC (0.13 mg/kg) prevented AKI, as demonstrated both by biomarkers and survival. Compatible with kidney protection APAC reduced the circulating levels of vascular destabilizing and pro-inflammatory angiopoietin-2 and syndecan-1. No tissue bleeding ensued. APAC and UFH were similarly eliminated via kidneys and liver. In contrast to UFH, APAC (0.13 mg/kg) was reno-protective in moderate and even severe IRI by attenuating vascular injury and innate immune activation.

    Full Text Available Severe acute pancreatitis (SAP characterized by atrocious progression and numerous complications often leads to a high mortality rate due to hypermetabolism, systemic inflammatory response syndrome (SIRS, and multiple organs dysfunction syndrome (MODS. Studies have revealed that both early enteral nutrition (EEN and emodin are potent agents in the management of SAP. However, whether the combined strategy is rational and more effective than either one alone remains unknown. In this regard, Wistar rats were treated with emodin-assisted EEN (EAEEN through enteral nutrient tubes after induction of SAP by retrograde infusion of 5.0% sodium taurocholate into the common pancreatic duct. Serum levels of amylase, tumor necrosis factor-alpha (TNF-α, angiotensin II (AngII, maleic dialdehyde (MDA, glutamic pyruvic transaminase (ALT, glutamic oxaloacetic transaminase (AST and C-reactive protein (CRP, intestinal secretory IgA (SIgA, pancreatic and hepatic myeloperoxidase (MPO activity as well as plasma levels of D-lactate and endotoxin were measured. In addition, pathologic alterations of pancreas and liver were observed microscopically. We found that EAEEN could significantly ameliorate these parameters and prevent pancreas and liver from serious damage. In conclusion, Our results indicated that EAEEN could exert beneficial effects on experimental SAP and obviously abate the severity of secondary hepatic injury. The combined strategy was safe and more effective than either one alone in the acute stage of SAP. This study also provided an experimental base for the clinical treatment of SAP patients with EAEEN.

    Tuberculosis and severe acute malnutrition (SAM) in children pose a major treatment and care challenge in high HIV burden countries in Africa. We investigated the prevalence of Tuberculosis notifications among hospitalised under-five children with severe acute malnutrition. A retrospective review of medical records for all children aged 0-59 months admitted to the University Teaching Hospital from 2009 to 2013 was performed. Descriptive statistics were employed to estimate TB caseload. Logistic regression was used to identify predictors of the TB caseload. A total of (n = 9540) under-five children with SAM were admitted over the period reviewed. The median age was 16 months (IQR 11-24) and the proportion diagnosed with TB was 1.58% (95% CI 1.3, 1.8) representing 151 cases. Of these, only 37 (25%) were bacteriologically confirmed cases. The HIV seroprevalence of children with SAM and TB was 46.5%. Children with SAM and TB were 40% more likely to die than children with SAM and without TB. Tuberculosis contributes to mortality among children with SAM in high TB and HIV prevalence settings. The under detection of cases and association of TB with HIV infection in malnutrition opens up opportunities to innovate integrative case finding approaches beyond just HIV counselling and testing within existing mother and child health service areas to include TB screening and prevention interventions, as these are critical primary care elements.

    Full Text Available Clinical manifestations of hepatitis A virus (HAV infection vary from mild to fulminant hepatic failure (FHF in adults. We investigated the relationship between laboratory findings, including viral load, and clinical outcomes in patients with acute hepatitis A (AHA and evaluated predictive factors for severe acute hepatitis (s-AH.We analyzed the clinical manifestations of AHA in 770 patients. Patients with a prothrombin time (PT of less than 40% of normal were classified as s-AH and included 4 patients with FHF, 11 patients with acute renal failure, and 3 patients with prolonged jaundice (n = 128. Other patients were defined as mild acute hepatitis (m-AH (n = 642. Serum samples were obtained from 48 patients with acute hepatitis A. Among them, 20 with s-AH, and 28 with m-AH, were tested for HAV RNA titer.In a multivariate analysis, age (HR = 1.042, P = 0.041, peak creatinine (HR = 4.014, P = 0.001, bilirubin (HR = 1.153, P = 0.003, alanine aminotransferase (ALT (HR = 1.001, P < 0.001, initial lactate dehydrogenase (LDH (HR = 1.000, P = 0.045 and total cholesterol (HR = 0.978, P < 0.001 were independent factors for s-AH. Serum HAV RNA was detected in 20/20 (100% patients with s-AH and 22/28 (78.6% patients with m-AH. In a multivariate analysis of the 48 patients who were tested for HAV RNA, peak ALT (HR = 1.001, P = 0.004 and HAV RNA titer (HR = 2.076, P = 0.012 were independent factors for s-AH.Clinical factors including age, peak creatinine, bilirubin, ALT, initial LDH and total cholesterol were independent factors for s-AH in a multivariate analysis. In particular, HAV load strongly correlated with the severity of hepatitis A.

    We have performed burr hole surgery in the emergency room for severe acute subdural hematoma from April 2007 in twenty five patients. All patients were deep comatose and showed cerebral herniation sign with bilateral pupillary abnormalities. Burr hole surgeries were performed as soon as possible after CT evaluation. Continually decomporresive craiectomies were followed if clinical improvements were achieved and mild baribiturate-moderate hypothermia combined (MB-MH) therapy was induced postoperatively in some cases. The mean average was 65.6 years (range 16-93). The causes of head injuries were traffic accident in 9, fall down in 13 and unknown in 3. The mean Glasgow coma scale (GCS) on admission was 4.4 (range 3-9). The mean time interval from arrival to burr hole surgery was 33.5 minutes (range 21-50 minutes). Decompressive craniectomy was indicated in 14 cases and MB-MH therapy was induced in 13 cases. The overall clinical outcome consisted of good recovery in 3, moderate disability in 2, severe disability in 3, persistent vegetative state in 3 and death in 14. Favorable results can be expected even in patients with serious acute subdural hematoma. Emergent burr hole surgery was effective to decrease intracranial pressure rapidly and to save time. So active burr hole surgery in the emergency room is strongly recommended to all cases of severe acute subdural hematoma. (author)

  18. Oxidation-Reduction Potential as a Biomarker for Severity and Acute Outcome in Traumatic Brain Injury

    2016-01-01

    Full Text Available There are few reliable markers for assessing traumatic brain injury (TBI. Elevated levels of oxidative stress have been observed in TBI patients. We hypothesized that oxidation-reduction potential (ORP could be a potent biomarker in TBI. Two types of ORP were measured in patient plasma samples: the static state of oxidative stress (sORP and capacity for induced oxidative stress (icORP. Differences in ORP values as a function of time after injury, severity, and hospital discharge were compared using ANOVAs with significance at p≤0.05. Logit regression analyses were used to predict acute outcome comparing ORP, Injury Severity Score (ISS, Abbreviated Injury Scale (AIS, and Glasgow Coma Scale (GCS. Antioxidant capacity (icORP on day 4 was prognostic for acute outcomes (p 7.25 μC. IcORP was a better predictor than ISS, AIS, or GCS scores. sORP increased in those with the highest ISS values (p<0.05. Based on these findings ORP is useful biomarker for severity and acute outcome in TBI patients. Changes in ORP values on day 4 after injury were the most prognostic, suggesting that patients’ response to brain injury over time is a factor that determines outcome.

    The aim of the study was to assess the ability of MRI to differentiate between the two forms of severity of acute pancreatitis (AP), which is important for the detection of patients who require intensive monitoring and therapy. The second objective was to evaluate whether the distinction would be possible regardless of the MRI equipment. Magnetic resonance imaging was performed before and after intravenous administration of a gadolinium (Gd) chelate at 1.0 T using the breath-hold multislice rapid gradient-echo turbo fast low-angle shot (FLASH) sequence in 14 patients, and at 1.5 T with the 2D FLASH(50) sequence with fat saturation in 18 patients with acute pancreatitis early in the course of the disease. The patients were classified according to the Atlanta classification system as having the mild (MAP) or severe (SAP) form of the disease. At 1.0 T with use of a body coil, contrast-enhanced MRI failed to distinguish mild from severe pancreatitis. At 1.5 T with a phased-array body coil, the signal intensities of the patients with SAP were statistically significantly lower than those of the MAP group. Our initial clinical experience suggests that MRI with a sufficient magnetic field gradient strength may be useful for separating the two forms of acute pancreatitis in their early phases. (orig.)

    Objective: To investigate the correlation between the grading of gastic bare area involvement (GBAI) and the CT severity index (CTSI) in acute pancreatitis (AP). Methods: CT scannings and clinical data of 112 consecutive patients with AP were studied retrospectively. The involvement of GBA and CTSI score of AP were graded using GBA involvement criteria and CT severity index (CTSI) criteria respectively. The grade of GBAI in AP was correlated with the grade of CT severity index (CTSI) by way of Ranking Test. Results: The Pearson Correlation coefficient of morphologic grade of GBAI in AP correlated with CTSI severity classified by CTSI was 0.729, and its P <0.001, which indicated the statistic value between these two grading systems. Conclusion: GBAI in AP is strongly correlated with CTSI and can be used as a supplementary criteria to the CTSI criterion to evaluate thoroughly the range, degree and severity of the AP. (authors)

    Conservative, non-antibiotic and non-surgical management of acute diverticulitis is currently being investigated. To better inform clinical decisions, better understanding of disease mechanisms, disease burden and severity is needed. Literature search of risk factors, pathophysiology, epidemiology and disease burden/severity reported over the last decade. Acute diverticulitis is a common disease and has a high disease burden. Incidence of hospital admissions is reported around 71 per 100,000 population, with reported increase in several subpopulations over the last decades. The incidence is likely to increase further with the aging populations. Risk factors for left-sided acute diverticulitis include dietary, anthropometric and lifestyle factors. Disease mechanisms are still poorly understood, but a distinction between inflammation and infection is emerging. The integrative and complex role of the gut microbiota has become an interesting factor for both understanding the disease as well as a potential target for intervention using probiotics. Mild, self-limiting events are increasingly reported from studies of successful non-antibiotic management in a considerable number of cases. Risk markers of progression to or presence of severe, complicated disease are needed for better disease stratification. Current risk stratification by clinical, imaging or endoscopic means is imperfect and needs validation. Long-term results from minimal-invasive and comparative surgical trials may better help inform clinicians and patients. Over- and under-treatment as well as over- and under-diagnosis of severity is likely to continue in clinical practice due to lack of reliable, robust and universal severity and classification systems. Better understanding of pathophysiology is needed.

    Posthemorrhagic anemia is a rare but important cause of anemia in neonates, second only to hemolytic anemia of newborn. Most cases of posthemorrhagic anemia are reported from fetomaternal hemorrhage or umbilical cord accidents in utero. This case report describes a preterm infant who developed severe anemia and shock immediately after delivery related to an acute hemorrhage through patent umbilical cord vessels secondary to a tear in the umbilical cord at the site of cord clamping. We believe that umbilical cord bleeding from errors in cord clamping could be an important cause of acute blood loss in the delivery room and that it may result in significant clinical morbidity, especially in extremely premature infants.

    A female patient who developed massive bilateral pneumonia with severe respiratory insufficiency during recovery from varicella, is presented. Blood serologic analyses detected the cause of infection--Mycoplasma pneumoniae, while Streptococcus pneumoniae was isolated by bacteriological examination of the sputum. M. pneumoniae is a causative agent of acute upper and lower respiratory airway infections with a frequently mild clinical picture. This agent rarely provokes massive pneumonia with severe clinical appearance as described in the patient, who had immunodeficiency due to previous infection with Varicella zoster virus.

    Influenza epidemiology in Africa is generally not well understood. Using syndrome definitions to screen patients for laboratory confirmation of infection is an established means to effectively conduct influenza surveillance. To compare influenza-related epidemiologic data, from October 2010 through March 2013, we enrolled hospitalized severe acute respiratory infection (SARI; fever with respiratory symptoms) and acute febrile illness (AFI; fever without respiratory or other localizing symptoms) patients from three referral hospitals in Ghana. Demographic and epidemiologic data were obtained from enrolled patients after which nasopharyngeal and oropharyngeal swabs were collected, and processed by molecular methods for the presence of influenza viruses. Of 730 SARI patients, 59 (8%) were influenza positive; of 543 AFI patients, 34 (6%) were positive for influenza. Both SARI and AFI surveillance yielded influenza A(H3N2) (3% versus 1%), A(H1N1)pdm09 (2% versus 1%), and influenza B (3% versus 4%) in similar proportions. Data from both syndromes show year-round influenza transmission but with increased caseloads associated with the rainy seasons. As an appreciable percentage of influenza cases (37%) presented without defined respiratory symptoms, and thus met the AFI but not the SARI definition, it is important to consider broader screening criteria (i.e., AFI) to identify all laboratory-confirmed influenza. The identified influenza transmission seasonality has important implications for the timing of related public health interventions. © 2016 The Authors.

    To investigate the efficacy of the treatment of severe acute pancreatitis (SAP) complicated by acute respiratory distress syndrome (ARDS) using continuous renal replacement therapy (CRRT) by evaluating the effect of CRRT on respiratory and circulatory function as well as serum cytokines level. Fifty four randomly selected patients with confirmed SAP complicated by ARDS after being admitted to intensive care unit (ICU) within 72 hr of onset were included in the study. Patients received mechanical respiratory support and CRRT. Arterial blood gas analysis was conducted and serum cytokine levels, including tumor necrosis factor alpha (TNF-α), interleukin 4 (IL-4) and interleukin 6 (IL-6), as well as C reactive protein (CRP) were evaluated respectively both before and 6h, 12h, and 24h after CRRT therapy. Peak inspiratory pressure and pulmonary compliance were also recorded. Arterial oxygen tension (PaO2), oxygenation index (OI) as well as dynamic pulmonary compliance were all elevated significantly, whereas peak inspiratory pressure significantly decreased at 6h, 12h and 24h after CRRT respectively; serum cytokine level and CRP significantly decreased (p < 0.05). CRRT can effectively reduce the level of inflammatory mediators, and improve respiratory and circulatory function.

Thirty-two recreationally strength-trained men were submitted to a graded exercise test to determine maximal oxygen consumption (VO2max: 41.56 ± 5.24 ml kg(-1) min(-1)), anaerobic threshold velocity (ATv: 8.3 ± 1.18 km h(-1)), and baseline performance (control) on the 1RM and SE (4 × 80 % 1RM to failure) tests. After the control tests, participants were randomly assigned to either a CR (20 g day(-1) for 7 days followed by 5 g day(-1) throughout the study) or a placebo (PL-dextrose) group, and then completed 4 experimental sessions, consisting of a 5-km run on a treadmill either continuously (90 % ATv) or intermittently (1:1 min at vVO2max) followed by either a leg- or bench-press SE/1RM test. CR was able to maintain the leg-press SE performance after the intermittent aerobic exercise when compared with C (p > 0.05). On the other hand, the PL group showed a significant decrease in leg-press SE (p ≤ 0.05). CR supplementation significantly increased bench-press SE after both aerobic exercise modes, while the bench-press SE was not affected by either mode of aerobic exercise in the PL group. Although small increases in 1RM were observed after either continuous (bench press and leg press) or intermittent (bench press) aerobic exercise in the CR group, they were within the range of variability of the measurement. The PL group only maintained their 1RM. In conclusion, the acute interference effect on strength performance observed in concurrent exercise may be counteracted by CR supplementation.

    Full Text Available Severe acute pancreatitis is associated with a systemic inflammatory response leading to a hypermetabolic, hypercatabolic condition; for those reasons, patients suffering from this disease require an excellent artificial nutritional support in order to maintain the structural integrity and the function of vital organs with minimal pancreatic secretion. Total parenteral nutrition has been the standard practice in the treatment of patients with severe acute pancreatitis because of the favorable outcomes of early nutritional support while avoiding pancreatic stimulation; however, recent evidence suggests there are potentially greater benefits with enteral as compared with parenteral nutrition, including fewer septic and metabolic complications and lesser costs. That is why present guidelines for the management of acute pancreatitis recommend that enteral instead of parenteral nutrition be used in patients with severe acute pancreatitis. La pancreatitis aguda, especialmente en su forma grave, está asociada con una respuesta inflamatoria sistémica que lleva a un estado de hipermetabolismo e hipercatabolismo, en el que se requiere un excelente soporte nutricional que permita mantener la integridad estructural y la función de los órganos vitales con un estímulo mínimo de la secreción pancreática. La nutrición parenteral total era el soporte de elección, que permitía obtener todos los beneficios de la nutrición temprana sin estimular la secreción pancreática; pero la evidencia actual muestra mayores beneficios con la nutrición enteral, porque se asocia con menos complicaciones infecciosas y metabólicas y con disminución en los costos. Por ello las guías actuales de tratamiento de la pancreatitis aguda grave recomiendan como primera elección el soporte nutricional enteral.

    Anaphylactoid purpura, also known as Henoch-Schönleinpurpura (HSP), is an IgA-mediated vasculitis that tends to be a benign disease of childhood. Up to 50% of cases are preceded by an upper tract respiratory infection caused by group-A beta-hemolytic streptococcus and present with the common tetrad of abdominal pain, arthritis, purpuric rash, and renal involvement. The majority of patients recover completely. Here we document a rare case of anaphylactoid purpura which manifested with skin lesions in the form of palpable purpura following about of acute gastroenteritis with severe dehydration; it was treated with a short regimen of steroid therapy, which resulted in the complete remission of the disease. We conclude that prompt diagnosis and multidisciplinary intervention will lead to appropriate management-consisting of the installation of early short-course steroid therapy and thus, prevent further complications and the recurrence of the disease.

    Psychological stress exacerbates many pathological conditions including inflammatory skin conditions. The effect of psychological stress on acute radiation-induced skin reactions has not been documented before. Here, we aimed to explore if psychological stress could aggravate skin reaction severity in breast cancer patients. We conducted a secondary analysis of patient data obtained during a randomised, controlled clinical trial for acute radiation-induced skin reaction severity in 78 breast cancer patients. Patients were assessed three times a week during treatment. Skin reaction severity was measured using the modified Radiation-Induced Skin Reaction Assessment Scale (RISRAS) and Radiation Therapy Oncology Group grades. Stress levels were determined using a 5-point LIKERT scale to rate physical well-being, managing stress levels, house, family, work and other commitments. A total of 20 patients (26%) of the 78-patient cohort were considered stressed. Skin reaction severity in stressed patients was twice that of non-stressed patients (p stressed patients were five times more likely to develop moist desquamation. Our results show that psychological stress aggravates skin reaction severity during radiation therapy. This research needs to be validated in a more rigorous manner by incorporating a validated scale such as the Distress Thermometer and Impact Thermometer in future skin trials. © 2017 John Wiley & Sons Ltd.

    Public health risks associated to infection by human coronaviruses remain considerable and vaccination is a key option for preventing the resurgence of severe acute respiratory syndrome coronavirus (SARS-CoV). We have previously reported that antibodies elicited by a SARS-CoV vaccine candidate based on recombinant, full-length SARS-CoV Spike-protein trimers, trigger infection of immune cell lines. These observations prompted us to investigate the molecular mechanisms and responses to antibody-mediated infection in human macrophages. We have used primary human immune cells to evaluate their susceptibility to infection by SARS-CoV in the presence of anti-Spike antibodies. Fluorescence microscopy and real-time quantitative reverse transcriptase polymerase chain reaction (RT-PCR) were utilized to assess occurrence and consequences of infection. To gain insight into the underlying molecular mechanism, we performed mutational analysis with a series of truncated and chimeric constructs of fragment crystallizable γ receptors (FcγR), which bind antibody-coated pathogens. We show here that anti-Spike immune serum increased infection of human monocyte-derived macrophages by replication-competent SARS-CoV as well as Spike-pseudotyped lentiviral particles (SARS-CoVpp). Macrophages infected with SARS-CoV, however, did not support productive replication of the virus. Purified anti-viral IgGs, but not other soluble factor(s) from heat-inactivated mouse immune serum, were sufficient to enhance infection. Antibody-mediated infection was dependent on signaling-competent members of the human FcγRII family, which were shown to confer susceptibility to otherwise naïve ST486 cells, as binding of immune complexes to cell surface FcγRII was necessary but not sufficient to trigger antibody-dependent enhancement (ADE) of infection. Furthermore, only FcγRII with intact cytoplasmic signaling domains were competent to sustain ADE of SARS-CoVpp infection, thus providing additional

    Children with acute and chronic malnutrition are at increased risk of morbidity and mortality following a diarrheal episode. To compare diarrheal disease severity and pathogen prevalence among children with and without acute and chronic malnutrition, we conducted a cross-sectional study of human immunodeficiency virus-uninfected Kenyan children aged 6-59 months, who presented with acute diarrhea. Children underwent clinical and anthropometric assessments and provided stool for bacterial and protozoal pathogen detection. Clinical and microbiological features were compared using log binomial regression among children with and without wasting (mid-upper arm circumference ≤ 125 mm) or stunting (height-for-age z score ≤ -2). Among 1,363 children, 7.0% were wasted and 16.9% were stunted. After adjustment for potential confounders, children with wasting were more likely than nonwasted children to present with at least one Integrated Management of Childhood Illness danger sign (adjusted prevalence ratio [aPR]: 1.3, 95% confidence interval [CI]: 1.0 to 1.5, P = 0.05), severe dehydration (aPR: 2.4, 95% CI: 1.5 to 3.8, P < 0.01), and enteroaggregative Escherichia coli recovered from their stool (aPR: 1.8, 1.1-2.8, P = 0.02). There were no differences in the prevalence of other pathogens by wasting status after confounder adjustment. Stunting was not associated with clinical severity or the presence of specific pathogens. Wasted children with diarrhea presented with more severe disease than children without malnutrition which may be explained by a delay in care-seeking or diminished immune response to infection. Combating social determinants and host risk factors associated with severe disease, rather than specific pathogens, may reduce the disparities in poor diarrhea-associated outcomes experienced by malnourished children.

    The roles of ghrelin and obestatin in AP remain controversial.This study investigates the effects and the predictive value of serum ghrelin and obestatin levels in the early stage of AP.A total of 193 consecutive patients with AP and 24 healthy controls were included. Patients were divided into mild acute pancreatitis (MAP), moderately severe acute pancreatitis (MSAP), and severe acute pancreatitis (SAP) groups. Serum levels of ghrelin and obestatin were measured on the first, third, and fifth days of hospitalization. The predictive value of serum ghrelin and obestatin levels on the first day in AP was examined using receiver-operating characteristic (ROC) curves.On the first day of hospitalization, the mean serum ghrelin level was significantly lower in patients with AP than in controls (P ghrelin concentration decreased with increasing AP severity and was lower in patients with SAP than in those with MAP and MSAP (P ghrelin level on the first day had some predictive value for AP severity (area under the ROC curve = 0.646), with an optimal cut-off value of 87.83 pg/mL. Logistic regression showed that the serum ghrelin level had independent predictive value for non-MAP (odds ratio = 10.94; 95% confidence interval, 5.08-23.55; P ghrelin and obestatin levels may be related to the progression of AP in the early stage. Only the serum ghrelin level is a potential predictor of AP severity in the early stage. Obestatin may be involved in the pathogenesis of AP caused by hypertriglyceridemia.

    Although the pathophysiology of acute pancreatitis appears to be greatly influenced by the production of ascites, little is known about the mechanism. To investigate the effects of pancreatitis-associated ascitic fluid (PAAF) on macrophage function, we examined the effects of PAAF obtained from a rat model of severe acute pancreatitis on the ability of peritoneal macrophages to produce tumor necrosis factor-alpha (TNF-alpha). In addition, we compared the responses of PAAF-treated and PAAF-untreated macrophages to lipopolysaccharide (LPS) by evaluating their TNF-alpha production and nuclear factor-kappaB (NFkappaB) activation. Incubation of peritoneal macrophages with the PAAF led to the rapid and prolonged activation of NF-kappaB and to TNF-alpha production. Pyrrolidine dithiocarbamate, a potent inhibitor of NF-kappaB activation, attenuated the macrophage TNF-alpha production by PAAF. Macrophages produced TNF-alpha in response to LPS, but the cytokine production was significantly reduced when macrophages were pretreated with PAAF. The suppression of TNF-alpha production by PAAF pretreatment accompanied the impairment of NF-kappaB activation in response to LPS. These results indicate that the PAAF of severe acute pancreatitis may play important roles in the pathologic course of this disease through its effects on macrophage function.

    Full Text Available Objective: to determine the time and development rate of acute lung injury (ALI in severe brain injury (SBI complicated by aspiration of gastric contents or blood. Subjects and methods. Twenty-nine patients aged 19 to 70 years, who had isolated SBI, of whom there were 24 males and 5 females, were examined. The patients were divided into 2 groups: those with aspiration of gastric contents (n=9 or blood (n=10. A control group included 10 patients with SBI without aspiration. A PiCCO plus device was used to determine pulmonary extravascular fluid. ALI was diagnosed in accordance with the recommendations of the Research Institute of General Reanimatology, Russian Academy of Medical Sciences. Results. SBI patients with aspiration of gastric contents or blood were found to have significantly increased pulmonary extravascular water (p<0.01 and a lower oxygenation index (<300, which correlated with each other. ALI was recorded in the first hours after injury in about 50% of cases in both patients with gastric contents aspiration and those with blood aspiration. Conclusion. In patients with SBI complicated by aspiration of gastric contents or blood, pulmonary extravascular fluid accumulation concurrent with other signs of injury may be regarded as a criterion for acute lung injury. Key words: severe brain injury, aspiration, acute lung lesion.

    Association of vitamin D deficiency with coronary heart disease (CHD) has been widely reported. Emerging data has shown high prevalence of vitamin D deficiency among Indians. However, this association has not been studied in Indians. A case-control study with 120 consecutive cases of first incident acute myocardial infarction (MI) and 120 age and gender matched healthy controls was conducted at All India Institute of Medical Sciences, New Delhi. The standard clinical and biochemical risk factors for MI were assessed for both cases and controls. Serum 25 (OH) vitamin D assay was performed from stored samples for cases and controls using radioimmunoassay. Vitamin D deficiency [25(OH) D tobacco and alcohol. They had higher waist hip ratio, total and LDL cholesterol. Multivariate logistic regression analysis revealed severe vitamin D deficiency [25(OH) vitamin D < 10 ng/ml] was associated with a risk of MI with an odds ratio of 4.5 (95% CI 2.2-9.2). This study reveals high prevalence of vitamin D deficiency among cases of acute MI and controls from India, with levels of 25 (OH)D being significantly lower among cases. Despite rampant hypovitaminosis, severe vitamin D deficiency was associated with acute MI after adjusting for conventional risk factors. This association needs to be tested in larger studies in different regions of the country. Copyright © 2015 Cardiological Society of India. Published by Elsevier B.V. All rights reserved.

    To compares the clinical features of patients infected with hepatitis E virus (HEV) with or without severe jaundice. In addition, the risk factors for HEV infection with severe jaundice were investigated. We enrolled 235 patients with HEV into a cross-sectional study using multi-stage sampling to select the study group. Patients with possible acute hepatitis E showing elevated liver enzyme levels were screened for HEV infection using serologic and molecular tools.HEV infection was documented by HEV antibodies and by the detection of HEV-RNA in serum. We used χ(2) analysis, Fisher's exact test, and Student's t test where appropriate in this study. Significant predictors in the univariate analysis were then included in a forward, stepwise multiple logistic regression model. No significant differences in symptoms, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, or hepatitis B virus surface antigen between the two groups were observed. HEV infected patients with severe jaundice had significantly lower peak serum levels of γ-glutamyl-transpeptidase (GGT) (median: 170.31 U/L vs 237.96 U/L, P = 0.007), significantly lower ALB levels (33.84 g/L vs 36.89 g/L, P = 0.000), significantly lower acetylcholine esterase (CHE) levels (4500.93 U/L vs 5815.28 U/L, P = 0.000) and significantly higher total bile acid (TBA) levels (275.56 μmol/L vs 147.03 μmol/L, P = 0.000) than those without severe jaundice. The median of the lowest point time tended to be lower in patients with severe jaundice (81.64% vs 96.12%, P = 0.000). HEV infected patients with severe jaundice had a significantly higher viral load (median: 134 vs 112, P = 0.025) than those without severe jaundice. HEV infected patients with severe jaundice showed a trend toward longer median hospital stay (38.17 d vs 18.36 d, P = 0.073). Multivariate logistic regression indicated that there were significant differences in age, sex, viral load, GGT, albumin, TBA, CHE, prothrombin index, alcohol

    Obesity is clearly an independent risk factor for increased severity of acute pancreatitis (AP), although the mechanisms underlying this association are unknown. Adipokines (including leptin and adiponectin) are pleiotropic molecules produced by adipocytes that are important regulators of the inflammatory response. We hypothesized that the altered adipokine milieu observed in obesity contributes to the increased severity of pancreatitis. Lean (C57BL/6J), obese leptin-deficient (LepOb), and obese hyperleptinemic (LepDb) mice were subjected to AP by six hourly intraperitoneal injections of cerulein (50 microg/kg). Severity of AP was assessed by histology and by measuring pancreatic concentration of the proinflammatory cytokines IL-1beta and IL-6, the chemokine MCP-1, and the marker of neutrophil activation MPO. Both congenitally obese strains of mice developed significantly more severe AP than wild-type lean animals. Severity of AP was not solely related to adipose tissue volume: LepOb mice were heaviest; however, LepDb mice developed the most severe AP both histologically and biochemically. Circulating adiponectin concentrations inversely mirrored the severity of pancreatitis. These data demonstrate that congenitally obese mice develop more severe AP than lean animals when challenged by cerulein hyperstimulation and suggest that alteration of the adipokine milieu exacerbates the severity of AP in obesity.

    Falls cause injury and death for persons of all ages, but risk of falls increases markedly with age. Hospitalization further increases risk, yet no evidence exists to support short-stay hospital-based fall prevention strategies to reduce patient falls. To investigate whether a fall prevention tool kit (FPTK) using health information technology (HIT) decreases patient falls in hospitals. Cluster randomized study conducted January 1, 2009, through June 30, 2009, comparing patient fall rates in 4 urban US hospitals in units that received usual care (4 units and 5104 patients) or the intervention (4 units and 5160 patients). The FPTK integrated existing communication and workflow patterns into the HIT application. Based on a valid fall risk assessment scale completed by a nurse, the FPTK software tailored fall prevention interventions to address patients' specific determinants of fall risk. The FPTK produced bed posters composed of brief text with an accompanying icon, patient education handouts, and plans of care, all communicating patient-specific alerts to key stakeholders. The primary outcome was patient falls per 1000 patient-days adjusted for site and patient care unit. A secondary outcome was fall-related injuries. During the 6-month intervention period, the number of patients with falls differed between control (n = 87) and intervention (n = 67) units (P=.02). Site-adjusted fall rates were significantly higher in control units (4.18 [95% confidence interval {CI}, 3.45-5.06] per 1000 patient-days) than in intervention units (3.15 [95% CI, 2.54-3.90] per 1000 patient-days; P = .04). The FPTK was found to be particularly effective with patients aged 65 years or older (adjusted rate difference, 2.08 [95% CI, 0.61-3.56] per 1000 patient-days; P = .003). No significant effect was noted in fall-related injuries. The use of a fall prevention tool kit in hospital units compared with usual care significantly reduced rate of falls. clinicaltrials.gov Identifier: NCT

    Full Text Available Background: Recent experience with pandemic influenza A(H1N1pdm09 highlighted the importance of global surveillance for severe respiratory disease to support pandemic preparedness and seasonal influenza control. Improved surveillance in the southern hemisphere is needed to provide critical data on influenza epidemiology, disease burden, circulating strains and effectiveness of influenza prevention and control measures. Hospital-based surveillance for severe acute respiratory infection (SARI cases was established in New Zealand on 30 April 2012. The aims were to measure incidence, prevalence, risk factors, clinical spectrum and outcomes for SARI and associated influenza and other respiratory pathogen cases as well as to understand influenza contribution to patients not meeting SARI case definition. Methods/Design: All inpatients with suspected respiratory infections who were admitted overnight to the study hospitals were screened daily. If a patient met the World Health Organization’s SARI case definition, a respiratory specimen was tested for influenza and other respiratory pathogens. A case report form captured demographics, history of presenting illness, co-morbidities, disease course and outcome and risk factors. These data were supplemented from electronic clinical records and other linked data sources. Discussion: Hospital-based SARI surveillance has been implemented and is fully functioning in New Zealand. Active, prospective, continuous, hospital-based SARI surveillance is useful in supporting pandemic preparedness for emerging influenza A(H7N9 virus infections and seasonal influenza prevention and control.

    We report four cases of acute pulmonary edema that occurred during treatment by intravenous tocolysis using nicardipine in pregnancy patients with no previous heart problems. Clinical severity justified hospitalization in intensive care unit (ICU) each time. Acute dyspnea has begun at an average of 63 hours after initiation of treatment. For all patients, the first diagnosis suspected was pulmonary embolism. The patients' condition improved rapidly with appropriate diuretic treatment and by modifying the tocolysis. The use of intravenous nicardipine is widely used for tocolysis in France even if its prescription does not have a marketing authorization. The pathophysiological mechanisms of this complication remain unclear. The main reported risk factors are spontaneous preterm labor, multiple pregnancy, concomitant obstetrical disease, association with beta-agonists, and fetal lung maturation corticotherapy. A better knowledge of this rare but serious adverse event should improve the management of patients. Nifedipine or atosiban, the efficiency of which tocolysis was also studied, could be an alternative.

    Acute kidney injury (AKI) secondary to near-drowning is rarely described and poorly understood. Only few cases of severe isolated AKI resulting from near-drowning exist in the literature. We report a case of near-drowning who developed to isolated AKI due to acute tubular necrosis (ATN) requiring dialysis. A 21-yr-old man who recovered from near-drowning in freshwater 3 days earlier was admitted to our hospital with anuria and elevated level of serum creatinine. He needed five sessions of hemodialysis and then renal function recovered spontaneously. Renal biopsy confirmed ATN. We review the existing literature on near-drowning-induced AKI and discuss the possible pathogenesis.

    Acute liver failure in neonates is rare and is frequently associated with an unfavourable outcome. There is no curative treatment other than liver transplantation. Screening for viral, metabolic, toxic or vascular disease is essential to assess the prognosis and to guide specific treatment. Hepatic haemorrhage in neonates is often associated with bacterial infection, trauma and coagulopathies.

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

    Full Text Available Acute interstitial nephritis (AIN is a condition in which acute kidney injury (AKI is characterized by the histological finding of interstitial inflammation. Hyponidd is an ayurvedic drug containing Momordica charantia, Gymnema sylvestre, Swertia chirata, etc., used for the treatment of Type 2 diabetes mellitus (DM and polycystic ovarian disease as an insulin sensitizer. There are no case reports of AIN caused by this drug yet. We report a biopsy-proven case of AKI due to severe AIN associated with the use of hyponidd tablet in a 60-year-old male with DM and hypertension. As these types of various indigenous compounds are used as home remedies in our country, awareness about the possible adverse effects of these agents among physicians is very important in the early diagnosis and management.

    Acute myocardial infarction is thought to occur at sites of minor coronary stenosis. Recent data challenge this and also propose a role for coronary artery movement (CAM) in plaque instability. We examined the relationship between coronary stenosis severity, CAM pattern, and infarct-related lesions (IRLs) in acute myocardial infarction. We investigated 203 consecutive patients with ST-segment elevation myocardial infarction after successful fibrinolysis. Quantitative coronary angiography, CAM pattern, and extent score (atheroma burden) analysis was performed for each coronary artery segment. The IRL stenosis was at least moderate (>50%) and severe (>70%) in 78% and 31% of patients, respectively. Culprit arteries were associated with higher atheroma extent scores (25.2 vs 21.6, P 70% vs Compression CAM was also strongly associated with culprit segments (OR 3.4, 95% CI 2.6-4.5, P compression CAM and stenosis severity were strongly correlated, with the likelihood of a coronary segment having compression CAM progressively increasing with worsening stenosis (OR 56.4, 95% CI 37.9-83.8, P 70% vs relationship between stenosis severity and IRLs. Our study also raises the hypothesis that compression CAM may accelerate atherosclerosis and predispose to plaque vulnerability. Copyright 2010 Mosby, Inc. All rights reserved.

A 31-year-old soldier man who works in Aceh Singkil, Indonesia which is an endemic malaria area presented with a paroxysm of fever, shaking chills and sweats over four days, headache, arthralgia, abdominal pain, pale, jaundice, and oliguria. Urinalysis showed hemoglobinuria. Blood examination showed hemolytic anemia, thrombocytopenia, and hyperbilirubinemia. Falciparum malaria was then confirmed by peripheral blood smear, antimalarial medications were initiated, and hemodialysis was performed for eight times. The patient’s condition and laboratory results were quickly normalized. We report a case of P. falciparum-induced severe malaria with AKI and jaundice. The present case suggests that P. falciparum may induce severe malaria with life-threatening complications, early diagnosis and treatment is important to improve the quality of life of patients. Physicians must be alert for correct diagnosis and proper management of imported tropical malaria when patients have travel history in endemic areas.

    Severe acute pancreatitis (SAP) is recognized as critical refractory disease. The case fatality rate of SAP is as high as 36%-50%. Although significant progress has been achieved on the treatment of severe acute pancreatitis (SAP) by Integrated Traditional Chinese Medicine (TCM) and Western Medicine (WM), there still exist some difficulties hindering the further improvement of therapeutic efficacy. The hot issues includes: unconfirmative curative effects and diverse treatment principles, complicated predictive scoring systems and inaccurate markers for the severity stratification, unproved new therapeutic tools and controversial methods waiting more high qualified evidence, unclarified mechanism of Integrated TCM and WM. In order to overcome the difficulties, we aim to launch the clinical pathway of Integrated TCM and WM, to strengthen the unity of multidisciplinary cooperation. We also need to keep the efforts on screening the markers for early evaluation and prediction of disease severity, improving the diagnosis and treatment, exploring the mechanism of Traditional Chinese Medicine in treating SAP with more high quality basic and clinical research. Based on these efforts, we could provide better treatments and prognosis for SAP patients.

    The "best" operation in the setting of acute complicated diverticulitis has been debated for decades. Multiple studies, including a recent prospective randomized trial, have reported improved outcomes with primary anastomosis. The aim of this study was to determine whether surgeon or patient-specific factors drives the choice of operative procedure. Consecutive adult patients with sigmoid diverticulitis, requiring emergent operative treatment for acute complicated diverticulitis, from 1997 to 2012 at an academic medical center, were identified from a prospectively maintained complications database. Patient characteristics, surgeon, choice of operation, and outcomes including postoperative complications and stoma reversal were noted. The use of primary anastomosis and associated outcomes between colorectal and noncolorectal surgeons were compared. There were 151 patients who underwent urgent resection during the study period, and 136 met inclusion criteria. Eighty-two resections (65.1%) were performed by noncolorectal surgeons and 44 by colorectal surgeons (34.9%). Noncolorectal surgeons performed more Hartmann procedures (68.3% vs 40.9%, p = 0.01) despite similar demographics, American Society of Anesthesiologists (ASA) classification, and Hinchey stage. Length of stay, time to stoma reversal, ICU days, and postoperative complications were lower in the colorectal group (43.2% vs 16.7, p = 0.02). Although patient-specific factors are important, surgeon is a potent predictor of operation performed in the setting of severe acute diverticulitis. A more aggressive approach to primary anastomosis may lower the complication rate after surgical treatment for severe acute diverticulitis. Copyright © 2014 American College of Surgeons.

Retrospective observational study from 2003 to 2007 with a median follow-up period of 2.2 years (range 11 d-5.4 y) postoperatively. Private referral veterinary center. Eight cats. None. Quantitative data included preoperative physical and clinicopathologic values. Qualitative parameters included preoperative ultrasonographic interpretation, perioperative and intraoperative feeding tube placement, presence of free abdominal fluid, intraoperative closed suction abdominal drain placement, postoperative complications, microbiological culture, and histopathology. Common presenting clinical signs included lethargy, anorexia, and vomiting. Leukocytosis and hyponatremia were present in 5 of 8 cats. Hypokalemia, increased total bilirubin, and hyperglycemia were present in 6 of 8 cats. Elevated alanine aminotransferase and aspartate transferase were present in all cats. Surgery for extrahepatic biliary obstruction was performed in 6 cats, pancreatic abscess in 3 cats, and pancreatic necrosis in 1 cat. Six of the 8 cats survived. Five of the 6 cats that underwent surgery for extrahepatic biliary obstruction and 1 cat that underwent pancreatic necrosectomy survived. All 5 of the cats with extrahepatic biliary obstruction secondary to pancreatitis survived. The 2 nonsurvivors included a cat with a pancreatic abscess and a cat with severe pancreatitis and extrahepatic biliary obstruction secondary to a mass at the gastroduodenal junction. Postoperative complications included progression of diabetes mellitus, septic peritonitis, local gastrostomy tube stoma inflammation, local gastrostomy tube stoma infection, and mild dermal suture reaction. Cats with severe acute pancreatitis and concomitant extrahepatic biliary obstruction, pancreatic necrosis, or pancreatic abscesses may benefit from surgical intervention. Cats with extrahepatic

    The incidence of diverticulosis and diverticular disease of the colon is increasing worldwide. Although the majority of patients remains asymptomatic long-life, the prevalence of diverticular disease of the colon, including acute diverticulitis, is substantial and is becoming a significant burden on National Health Systems in terms of direct and indirect costs. Focus is now being drawn on identifying the correct therapeutic approach by testing various treatments. Fiber, non-absorbable antibiotics and probiotics seem to be effective in treating symptomatic and uncomplicated patients, and 5-aminosalicylic acid might help prevent acute diverticulitis. Unfortunately, robust evidence on the effectiveness of a medical strategy to prevent acute diverticulitis recurrence is still lacking. We herein provide a concise review on the effectiveness and future perspectives of these treatments. PMID:26752946

    Full Text Available An algorithm of choosing adequate vitamin combination for children's acute respiratory diseases is suggested on the basis of Pikovit vitamin complex (KRKA, Slovenia. It is emphasized that the choice of vitamins should be based on the peculiarities of their metabolism and their role in the body. The importance of vitamin therapy is in its immunomodifying effect and increasing child's abilities for adaptation. Choice of vitamin and mineral complex for seasonal child ARD prevention depends on physiological vitamin doses and the fact that vitamin and mineral complexes containing iron and copper should be excluded in the acute phase of the disease. Latest research data is provided demonstrating the inadvisability of using iron and copper additives to children with ARD. The article provides information on the necessity of qualified primary inspection of the sick child, diagnosing activities, composing an individual diet, vitamin and pharmacological therapy.Key words: polyvitamin products, prevention, acute respiratory infections, children.

    Acute antibody-mediated rejection is an unsolved issue in transplantation, especially in the context of pretransplant immunization. The deleterious effect of preformed cytotoxic anti-HLA antibodies through complement activation is well proven, but very little is known concerning complement blockade to prevent/cure this rejection. Here, we used a baboon model of preimmunization to explore the prevention of acute antibody-mediated rejection by an early inhibition of the classical complement pathway using human recombinant C1-inhibitor. Baboons were immunized against peripheral blood mononuclear cells from allogeneic donors and, once a specific and stable immunization had been established, they received a kidney from the same donor. Rejection occurred at day 2 posttransplant in untreated presensitized recipients, with characteristic histological lesions and complement deposition. As recombinant human C1-inhibitor blocks in vitro cytotoxicity induced by donor-specific antibodies, other alloimmunized baboons received the drug thrice daily intravenously during the first 5 days after transplant. Rejection was prevented during this treatment but occurred after discontinuation of treatment. We show here that early blockade of complement activation by recombinant human C1-inhibitor can prevent acute antibody-mediated rejection in presensitized recipients. This treatment could also be useful in other forms of acute antibody-mediated rejection caused by induced antibodies.

    Severe thalassemia diseases are a major health problem in Southeast Asia. In Cambodia, there has never been a significant program for prevention or control of severe thalassemia. We, therefore, studied the effect of a health education program on severe thalassemia prevention and control in Phnom Penh, Cambodia. A quasi-experimental study in several communities around Phnom Penh was done. The respective intervention and control group comprised 124 and 117 people, between 18 and 40 years of age, male and female. Pre- and post-tests using a validated and reliable questionnaire were performed in the intervention group and one test was done in the control group. A health education program was organized to give important information to the intervention group and, at the end of the process, to the control group. The outcomes were evaluations of their knowledge and attitude vis-à-vis severe thalassemia prevention and control, and participating in thalassemia screening. Among participants in the intervention group, 105 (84.7%) considered undergoing blood screening vs. 65 (55.6%) in the control group ( p -value < 0.001). In the intervention group, the respective mean scores for knowledge and attitude to a prevention and control program for severe thalassemia before and after health education were 2.6 VS 6.5 ( p -value < 0.001) and 4.6 VS 6.5 ( p -value < 0.001). The intention to undergo screening was significantly higher in the intervention group than the control group. Knowledge and attitude towards prevention and control of severe thalassemia was significantly improved in the intervention group. Health education clearly heightens awareness and improves consideration of screening for prevention and control of severe thalassemia.

  4. Circulating Microvesicles Are Elevated Acutely following Major Burns Injury and Associated with Clinical Severity.

    Directory of Open Access Journals (Sweden)

    Kieran P O'Dea

    Full Text Available Microvesicles are cell-derived signaling particles emerging as important mediators and biomarkers of systemic inflammation, but their production in severe burn injury patients has not been described. In this pilot investigation, we measured circulating microvesicle levels following severe burns, with severe sepsis patients as a comparator group. We hypothesized that levels of circulating vascular cell-derived microvesicles are elevated acutely following burns injury, mirroring clinical severity due to the early onset and prevalence of systemic inflammatory response syndrome (SIRS in these patients. Blood samples were obtained from patients with moderate to severe thermal injury burns, with severe sepsis, and from healthy volunteers. Circulating microvesicles derived from total leukocytes, granulocytes, monocytes, and endothelial cells were quantified in plasma by flow cytometry. All circulating microvesicle subpopulations were elevated in burns patients on day of admission (day 0 compared to healthy volunteers (leukocyte-microvesicles: 3.5-fold, p = 0.005; granulocyte-microvesicles: 12.8-fold, p<0.0001; monocyte-microvesicles: 20.4-fold, p<0.0001; endothelial- microvesicles: 9.6-fold, p = 0.01, but decreased significantly by day 2. Microvesicle levels were increased with severe sepsis, but less consistently between patients. Leukocyte- and granulocyte-derived microvesicles on day 0 correlated with clinical assessment scores and were higher in burns ICU non-survivors compared to survivors (leukocyte MVs 4.6 fold, p = 0.002; granulocyte MVs 4.8 fold, p = 0.003. Mortality prediction analysis of area under receiver operating characteristic curve was 0.92 (p = 0.01 for total leukocyte microvesicles and 0.85 (p = 0.04 for granulocyte microvesicles. These findings demonstrate, for the first time, acute increases in circulating microvesicles following burns injury in patients and point to their potential role in propagation of sterile SIRS

    The study aims to assess and compare the predicting ability of some scores and biomarkers in acute pancreatitis. We prospectively collected data from 269 patients diagnosed of acute pancreatitis, admitted to Virgen de las Nieves University Hospital between June 2010 and June 2012. Blood urea nitrogen (BUN), C-reactive protein, and creatinine were measured on admission and after 48 h, lactate and bedside index for severity acute pancreatitis (BISAP) only on admission and RANSON within the first 48 h. Definitions from 2012 Atlanta Classification were used. Area under the curve (AUC) was calculated for each scoring system for predicting severe acute pancreatitis (SAP), mortality, and intensive care unit (ICU) admission, obtaining optimal cut-off values from the receiver operating characteristic curves. Eight (3%) patients died, 17 (6.3%) were classified as SAP, and 10 (3.7%) were admitted in ICU. BISAP was the best predictor on admission for SAP, mortality, and ICU admission with an AUC of 0.9 (95% CI 0.83-0.97); 0.97 (95% CI 0.95-0.99); and 0.89 (95% CI 0.79-0.99), respectively. After 48 h, BUN 48 h was the best predictor of SAP (AUC = 0.96 CI: 0.92-0.99); BUN 48 h and BISAP were the best predictors for mortality (AUC = 0.97 CI: 0.95-0.99) and creatinine 48 h for ICU admission (AUC = 0.96 CI: 0.92-0.99). Lactate showed an AUC of 0.79 (CI: 0.71-0.88), 0.87 (CI: 0.78-0.96), and 0.77 (CI: 0.67-0.87) for SAP, mortality, and ICU admission, respectively. All parameters were predictors for SAP, mortality, and ICU admission, but C-reactive protein on admission was only a significant predictor of SAP. Bedside index for severity acute pancreatitis is a good predictive system for SAP, mortality, and ICU admission, being useful for triaging patients for ICU management. Lactate could be useful for developing new scores. © 2017 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

    2014-01-01

    BACKGROUND: Acute otitis media (AOM) is a common childhood illness and the leading indication for antibiotic prescriptions for US children. Xylitol, a naturally occurring sugar alcohol, can reduce AOM when given 5 times per day as a gum or syrup, but a more convenient dosing regimen is needed for widespread adoption. METHODS: We designed a pragmatic practice-based randomized controlled trial to determine if viscous xylitol solution at a dose of 5 g 3 times per day could reduce the occurrence of clinically diagnosed AOM among otitis-prone children 6 months through 5 years of age. RESULTS: A total of 326 subjects were enrolled, with 160 allocated to xylitol and 166 to placebo. In the primary analysis of time to first clinically diagnosed AOM episode, the hazard ratio for xylitol versus placebo recipients was 0.88 (95% confidence interval [CI] 0.61 to 1.3). In secondary analyses, the incidence of AOM was 0.53 episodes per 90 days in the xylitol group versus 0.59 in the placebo group (difference 0.06; 95% CI –0.25 to 0.13); total antibiotic use was 6.8 days per 90 days in the xylitol group versus 6.4 in the placebo group (difference 0.4; 95% CI –1.8 to 2.7). The lack of effectiveness was not explained by nonadherence to treatment, as the hazard ratio for those taking nearly all assigned xylitol compared with those taking none was 0.93 (95% CI 0.56 to 1.57). CONCLUSIONS: Viscous xylitol solution in a dose of 5 g 3 times per day was ineffective in reducing clinically diagnosed AOM among otitis-prone children. PMID:24394686

    Full Text Available Contrast-induced AKI (CI-AKI has been one of the leading causes for hospital-acquired AKI and is associated with independent risk for adverse clinical outcomes including morbidity and mortality. The aim of this review is to provide a brief summary of the studies that focus on nonpharmacological strategies to prevent CI-AKI, including routine identification of at-risk patients, use of appropriate hydration regimens, withdrawal of nephrotoxic drugs, selection of low-osmolar contrast media or isoosmolar contrast media, and using the minimum volume of contrast media as possible. There is no need to schedule dialysis in relation to injection of contrast media or injection of contrast agent in relation to dialysis program. Hemodialysis cannot protect the poorly functioning kidney against CI-AKI.

    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.

    The accurate assessment and communication of the severity of acute allergic reactions is important to patients, clinicians, researchers, the food industry, public health and regulatory authorities. Severity has different meanings to different stakeholders with patients and clinicians rating the significance of particular symptoms very differently. Many severity scoring systems have been generated, most focusing on the severity of reactions following exposure to a limited group of allergens. They are heterogeneous in format, none has used an accepted developmental approach and none has been validated. Their wide range of outcome formats has led to difficulties with interpretation and application. Therefore there is a persisting need for an appropriately developed and validated severity scoring system for allergic reactions that works across the range of allergenic triggers and addresses the needs of different stakeholder groups. We propose a novel approach to develop and then validate a harmonized scoring system for acute allergic reactions, based on a data-driven method that is informed by clinical and patient experience and other stakeholders' perspectives. We envisage two formats: (i) a numerical score giving a continuum from mild to severe reactions that is clinically meaningful and is useful for allergy healthcare professionals and researchers; and (ii) a three grade based ordinal format that is simple enough to be used and understood by other professionals and patients. Testing of reliability and validity of the new approach in a range of settings and populations will allow eventual implementation of a standardized scoring system in clinical studies and routine practice.

    2009-01-01

    Full Text Available Introduction. Despite intensive research, efforts and clinical investigations on pathogenesis of acute pancreatitis (AP and system morbidity during the illness onset, mortality is still very high in the group of severe forms. A significantly high number of patients show moderate, self-limited forms of illness, with a minimal degree of systemic or local complications, with full recovery. However, some of them have a severe form, followed by a high percent of morbidity and mortality, and system organ failure. The distinction between mild and severe forms of AP within 24-48 hours of hospital admission is very important for the treatment of these patients. The usage of multifactorial scoring systems holds a lot of promise, reaching reliability in the disease severity estimation of approximately 70-80%. Objective. The main purpose of this prospective study was to assess the correlation of the Acute Physiology and Chronic Health Evaluation II (APACHE II and the Bernard Organ Failure Score (BOFS scoring systems in estimation of disease severity and outcome prediction. Methods. Sixty patients with AP participated in the study, all of them scored with the APACHE II and BOFS scores. The results were used for integration of laboratory and clinical parameters. Results. In our study, we had a highly significant correlation between the APACHE II and BOFS scores from the disease onset until the end of treatment. There was a highly significant correlation between these two scores and the serum C-reactive protein concentration level. Conclusion. The concept of the BOFS score has more advantages than the APACHE II score in the patients with severe forms of AP with organ dysfunction.

    To explore the feasibility of endoscopic retrograde cholangiopancreatography (ERCP) in pregnant women with severe acute biliary pancreatitis. In total, 24 pregnant patients with severe acute biliary pancreatitis were enrolled in our study between January 2003 and January 2008. Emergency ERCP and endoscopic nasobiliary drainage (ENBD) without fluoroscopy were performed successfully in all 24 patients within 12-72 hours of admission. Once stabilized, 15 patients in late pregnancy underwent a second ERCP with fluoroscopy to remove common bile duct (CBD) stones after pregnancy termination. Nine patients in early or mid-pregnancy continued gestating and underwent endoscopic retrograde biliary drainage (ERBD) with a second ERCP without fluoroscopy, and their stents and CBD stones were removed during a third ERCP with fluoroscopy 1 week after parturition. Among the mothers, all 24 patients were cured, and none of them died. The CBD stones in all 24 patients were completely removed with a two-step ERCP, and no serious post-ERCP complications occurred, although 2 patients had mild hemorrhage in the final ERCP to remove CBD stones. No recurrent pancreatitis or cholangitis occurred in patients who underwent ERBD. Among the infants, all survived without developmental problems or abnormality. Twenty infants were born at term; four infants were born prematurely at 35-37 weeks of gestation without developmental problems or complications. Emergency ERCP and ENBD without fluoroscopy in pregnant women with severe acute biliary pancreatitis are feasible and safe for both mothers and infants. It is also appropriate to remove CBD stones with two-step ERCP in pregnant women according to the stage of pregnancy.

    Introduction: The acute toxoplasmosis in the immunocompetent patient, unlike of the positive HIV patient, it is characterizes for prolonged fever, lymph node and nonspecific infectious symptoms, generally with benign course and without systemic commitment. This pathology acquired a very importance in the pregnancy people, where the primary infection can to derivates in the congenital transmission of the illness with irreversible sequels in newborn. Nevertheless, the travel of the people to inhospitable woodsy areas, and the contact with wild-type strain of toxoplasma gondii, to be permitted a new expression of the illness in the immunocompetent patient, with pulmonary, cardiovascular and central nervous system manifestations. They are a high risk for the patient life's. In this study, one case of severe pulmonary commitment for toxoplasma gondii in immunocompetent patient is review; he is admitted to Internal Medicine Service of the Militar Central Hospital's in Bogota. He has a favorable evolution and adequate survival. Objective: To describe the clinical characteristics and follow-up of one patient with severe pulmonary commitment caused by toxoplasma gondii. Design: Case report. Materials and methods: The clinical records of the one patient who was hospitalized in the Militar Central Hospital's in Bogota was reviewed and described. Afterwards, the existing literature on Acute toxoplasmosis in immunocompetent patient was reviewed in PubMed, MD consult and OVID databases. Conclusions: The toxoplasma gondii infection's in immunocompetent patient generally has a benign course without systemic manifestations; nevertheless, the exposure to wild-type strain can to be related with severe pulmonary commitment.

    The objective of this study was to explore the clinical manifestations and possible mechanisms of vancomycin-resistant enterococcus (VRE)-induced severe enteritis and extraenteric disseminations. In six patients with severe acute pancreatitis (SAP) complicated with acute infectious diarrhea, VRE was confirmed by bacterial genotyping, minimum inhibitory concentration testing, and empiric linezolid treatment. Samples collected from stools and peripancreatic effusions were used to compare the genotypes of VRE by pulsed-field gel electrophoresis and multilocus sequence typing and to validate the suspected extraenteric disseminations caused by VRE. To further elucidate the mechanisms of VRE-inflicted enteric mucosal injury, in vitro infection of human intestinal Caco-2 cell line with VRE was performed followed by inflammatory cytokine assays and morphological characterization by electron microscopy. All six VRE strains isolated from stool samples caused severe enteritis in SAP patients. The same strains further inflicted significant damage and induced inflammatory reactions in Caco-2 cells. Homologous assays demonstrated high homology between samples from stool and peripancreatic effusions in two patients, indicating the occurrence of extraenteric disseminations. Alterations in drug resistance and virulence of enterococci, part of the symbiotic bacteria, during the course of SAP may cause inflammatory injuries to enteric epithelium, resulting in enteritis and extraenteric disseminations.

    Hypercalcemia and severe osteolytic lesions are rare complications of acute lymphoblastic leukemia (ALL) in childhood. We report a case of a 3 years old boy who presented with prolonged fever, nausea, vomiting and increasing lower limbs pain. Skeletal X-rays and CT scan showed severe osteolytic lesions of the skull and extremities. Her physical examination showed multiple cervical lymph nodes. In laboratory tests, he had severe hypercalcemia. Parathyroid hormone (PTH) was not elevated. Despite the absence of circulating blasts, bone marrow biopsy revealed B-precursor (ALL). Hypercalcemia was initially treated with intravenous isotonic sodium chloride solution and diuretics but the serum calcium level normalized only after the beginning of corticosteroids and chemotherapy. The child responded initially to chemotherapy and eventually relapsed and died of septic shock. Acute leukemia must be considered in differential diagnosis in patients with hypercalcemia. A detailed examination even when there no circulating blasts in their peripheral blood smear, and if in doubt bone marrow aspiration should must be taken into consideration.

Objective: to study the relationship between the plasma concentration of TG, the outcome of the disease, and the markers of its severity in intensive care unit patients with early-stage acute respiratory distress syndrome (ARDS. Subjects and methods. The prospective study included 18 patients with acute lung injury (ALI, who needed respiratory support. For further analysis, all the patients were divided into groups with TG < 1.00 mmol/l (TGlow; n=7 and >1.00 mmol/l (TGhigh; n=11. Results. A negative correlation was found between plasma TG concentration and oxygenation index (PaO2/FiO2. In the TG^jgh group, extravas-cular lung water index was significantly higher and cardiac index was lower than those in the TGlow group. Among the deceased patients, there was a 1.03 mmol/l reduction in TG concentration by day 4 of the study whereas in the survivors, TG concentration increased by an average of 0.15 mmol/l (p=0.02. Conclusion. In the patients with ALI, the plasma concentration of TG is related to oxygenation impairments and the degree of pulmonary edema, as well as with the outcome of the disease. Key words: triglycerides, acute lung injury, extravascular lung water index, pulmonary edema.

    Tenascin-C is a matricellular protein related to brain injury. We studied serum tenascin-C in acute intracerebral hemorrhage (ICH) and examined the associations with severity and outcome following the acute event. Tenascin-C samples were obtained from 162 patients with acute hemorrhagic stroke and 162 healthy controls. Poor 90-day functional outcome was defined as modified Rankin Scale score > 2. Early neurological deterioration (END) and hematoma growth (HG) were recorded at 24 h. Patients had higher tenascin-C levels than controls. Tenascin-C levels were positively correlated with hematoma volume or National Institutes of Health Stroke Scale score at baseline. Elevated tenascin-C levels were independently associated with END, HG, 90-day mortality and poor functional outcome. Moreover, tenascin-C levels significantly predicted END, HG and 90-day outcomes under receiver operating characteristic curves. An increase in serum tenascin-C level is associated with an adverse outcome in ICH patients, supporting the potential role of serum tenascin-C as a prognostic biomarker for hemorrhagic stroke.

    Full Text Available Organ failure is an important factor causing death in patients with severe acute pancreatitis (SAP. In recent years, thanks to the further study of pathophysiology of SAP and the continuous accumulation of experience and technology, substantial progress has been made in the diagnosis and treatment of SAP complicated by organ failure. The clinical features of SAP complicated by organ failure and the measures to be strengthened in the treatment of SAP are summarized. Currently, it is thought that organ failure tends to appear once SAP occurs, so timely, standardized treatment can shorten the course of disease and significantly reduce mortality.

    Intravenous contrast medium (ICM) rarely induces anaphylactic reactions, including urticaria, hypotension and respiratory failure. Even the most modern ICM may cause such adverse events. Thrombocytopenia has been reported as an extreme rare consequence of ICM. Here we report on a case of a 72-year-old male patient with a self-limiting severe acute thrombocytopenia following administration of intravenous non-ionic low-osmolarity contrast medium. No such low platelet count has ever been reported. We also present a review of the literature.

    Full Text Available Patients with acute cholangitis require emergent biliary decompression. Those who are hemodynamically unstable on vasopressor support and mechanical ventilation are too critically ill to move outside of the intensive care unit. This prohibits performing Endoscopic Retrograde Cholangiopancreatography (ERCP in the endoscopy unit. Fluoroscopic guidance is required to confirm deep biliary cannulation during ERCP. There are a few reported cases of bedside ERCP using portable C-arm fluoroscopy unit or ultrasound guided cannulation. We present a unique case of life-saving emergent bedside ERCP in a severely ill patient with cholangitis and septic shock, using simple portable X-ray to confirm biliary cannulation.

    The System 80 + design is ABB-CE's standardized evolutionary Advanced Light Water Reactor (ALWR) design. It incorporates design enhancements based on Probabilistic Risk Assessment (PRA) insights, guidance from the ALWR Utility Requirements Document (URD), and US NRC's Severe Accident Policy. Major severe accident prevention and mitigation design features of the System 80 + design are described. The results of the System 80 + PRA are presented and the insights gained from the PRA sensitivity analyses are discussed. ABB-CE considered defense-in-depth for accident prevention and mitigation early in the design process and used robust design features to ensure that the System 80 + design achieved a low core damage frequency, low containment conditional failure probability, and excellent deterministic containment performance under severe accident conditions and to ensure that the risk was properly allocated among design features and between prevention and mitigation.

    To evaluate total serum calcium (TC) and albumin-corrected calcium (ACC) as prognostic severity factors in acute pancreatitis (AP). Ninety-six patients were included in the study. They were diagnosed with AP and admitted to the Hospital Regional de Veracruz within the time frame of January 2010 to December 2012. AP severity was determined through the updated Atlanta Classification (2013). TC and ACC values were measured in the first 24hours of admittance and the percentages of sensitivity (S), specificity (Sp), positive predictive value (PPV), negative predictive value (NPV), positive likelihood ratio (LR+), and negative likelihood ratio (LR-) were calculated through ROC curves and contingency tables. In accordance with the updated Atlanta Classification, 70 patients presented with mild AP, 17 with moderately severe AP, and 9 with severe AP. Of the patient total, 61.5% were women, and 69.8% presented with biliary etiology. The maximum TC cut-off point was 7.5mg/dL, with values of S, 67%; Sp, 82%; PPV, 27%, and NPV, 96%. The maximum ACC cut-off point was 7.5mg/dL, with values of S, 67%; Sp, 90%; PPV, 40%; NPV, 96%. Both had values similar to those of the Ranson and APACHE II prognostic scales. TC and ACC, measured within the first 24hours, are useful severity predictors in acute pancreatitis, with sensitivity and predictive values comparable or superior to those of the conventional prognostic scales.

    Relapse of leukemia in the postchemotherapy phase contributes to the poor prognosis and survival in patients with acute myeloid leukemia (AML). In an international phase IV trial (ClinicalTrials.gov; NCT01347996), 84 patients with AML in first complete remission who had not undergone transplantation received immunotherapy with histamine dihydrochloride (HDC) and low-dose IL-2 with the aim of preventing relapse. The dynamics of myeloid cell counts and expression of activation markers was assessed before and after cycles of immunotherapy and correlated with clinical outcome in terms of relapse risk and survival. During cycles, a pronounced increase in blood eosinophil counts was observed along with a reduction in monocyte and neutrophil counts. A strong reduction of blood monocyte counts during the first HDC/IL-2 treatment cycle predicted leukemia-free survival. The HDC component of the immunotherapy exerts agonist activity at histamine type 2 receptors (H2Rs) that are expressed by myeloid cells. It was observed that the density of H 2 R expression in blood monocytes increased during cycles of immunotherapy and that high monocyte H 2 R expression implied reduced relapse risk and improved overall survival. Several other activation markers, including HLA-DR, CD86, and CD40, were induced in monocytes and dendritic cells during immunotherapy but did not predict clinical outcome. In addition, expression of HLA-ABC increased in all myeloid populations during therapy. A low expression of HLA-ABC was associated with reduced relapse risk. These results suggest that aspects of myeloid cell biology may impact clinical benefit of relapse-preventive immunotherapy in AML. © Society for Leukocyte Biology.

    Oxidative stress plays an important role in cadmium-induced liver injury. Nuclear factor erythroid 2-related factor 2 (Nrf2) is a transcription factor that up-regulates cytoprotective genes in response to oxidative stress. To investigate the role of Nrf2 in cadmium-induced hepatotoxicity, Nrf2-null mice, wild-type mice, kelch-like ECH-associated protein 1-knockdown (Keap1-KD) mice with enhanced Nrf2, and Keap1-hepatocyte knockout (Keap1-HKO) mice with maximum Nrf2 activation were treated with cadmium chloride (3.5 mg Cd/kg, i.p.). Blood and liver samples were collected 8 h thereafter. Cadmium increased serum alanine aminotransferase (ALT) and lactate dehydrogenase (LDH) activities, and caused extensive hepatic hemorrhage and necrosis in the Nrf2-null mice. In contrast, Nrf2-enhanced mice had lower serum ALT and LDH activities and less morphological alternations in the livers than wild-type mice. H{sub 2}DCFDA (2′,7′-dichlorodihydrofluoresein diacetate) staining of primary hepatocytes isolated from the four genotypes of mice indicated that oxidative stress was higher in Nrf2-null cells, and lower in Nrf2-enhanced cells than in wild-type cells. To further investigate the mechanism of the protective effect of Nrf2, mRNA of metallothionein (MT) and other cytoprotective genes were determined. Cadmium markedly induced MT-1 and MT-2 in livers of all four genotypes of mice. In contrast, genes involved in glutathione synthesis and reducing reactive oxygen species, including glutamate-cysteine ligase (Gclc), glutathione peroxidase-2 (Gpx2), and sulfiredoxin-1 (Srxn-1) were only induced in Nrf2-enhanced mice, but not in Nrf2-null mice. In conclusion, the present study shows that Nrf2 activation prevents cadmium-induced oxidative stress and liver injury through induction of genes involved in antioxidant defense rather than genes that scavenge Cd. -- Highlights: ► Cadmium caused extensive hepatic hemorrhage and necrosis in Nrf2-null mice. ► Keap1-KD and Keap1-HKO mice

The prevalence and burden of severe COPD exacerbations remain high, despite recognition of the importance of exacerbation prevention and the availability of new treatment options. Severe COPD exacerbations are associated with high mortality, have negative impact on quality of life, are linked to cardiovascular complications, and are a significant burden on the health-care system. This review identified risk factors that contribute to the development of severe exacerbations, treatment options (bronchodilators, antibiotics, corticosteroids [CSs], oxygen therapy, and ventilator support to manage severe exacerbations, and strategies to prevent readmission to hospital. Risk factors that are amenable to change have been highlighted. A number of bronchodilators have demonstrated successful reduction in risk of severe exacerbations, including long-acting muscarinic antagonist or long-acting β2-agonist mono- or combination therapies, in addition to vaccination, mucolytic and antibiotic therapy, and nonpharmacological interventions, such as pulmonary rehabilitation. Recognition of the importance of severe exacerbations is an essential step in improving outcomes for patients with COPD. Evidence-based approaches to prevent and manage severe exacerbations should be implemented as part of targeted strategies for disease management. Keywords

    To clarify whether tolerance to irrigation pressure could be modified over varying degrees of kidney obstruction during the endoscopic treatment of kidney stones in a rat model. A total of 126 rats were randomly allocated into 2 experimental groups and a control group. The experimental groups underwent a surgical procedure to induce mild (group M, n = 60) or severe (group S, n = 60) hydronephrosis. In each group, the rats were then randomly allocated into 4 subgroups (M0 to M3 and S0 to S3) of respectively 6, 18, 18, and 18 rats. Groups 0 to 3 were respectively perfused with 0 (no irrigation), 20, 60, and 100 mm Hg pressure fluid. The control group underwent no surgical procedures and was only perfused with 100 mm Hg pressure fluid. Acute kidney injuries were assessed by analyzing the kidney microstructure, tubular cell apoptosis, kidney injury molecule-1, and cysteine-rich 61 (Cyr61/CCN1) expression using immunohistochemistry. No abnormalities were observed for the control group, groups 0, or 1. In group 2, abnormalities were observed only in the S group, whereas all kidneys in group 3 suffered acute kidneys injuries, along with occurrence of tubular cells necrosis, increased apoptosis, and increased expression of kidney injury molecule-1 and Cyr61. Rats with severely obstructed kidneys were more likely to suffer acute kidney injuries than those with less obstructed kidneys when exposed to higher kidney irrigation pressures. This suggests that the pressure should be controlled and reduced when performing endourologic procedures in the context of kidney obstruction. Crown Copyright © 2013. Published by Elsevier Inc.

    1) To alert the clinician that increasing rate and depth of breathing during treatment of acute asthma may be a manifestation of metabolic acidosis with hyperventilation rather than worsening airway obstruction; and 2) to describe the frequency of metabolic acidosis with hyperventilation in children with severe acute asthma admitted to our pediatric intensive care unit. Retrospective medical record review. University-affiliated children's hospital. All patients admitted to the pediatric intensive care unit with a diagnosis of asthma between January 1, 2005, and December 31, 2005. None. Fifty-three patients with asthma (median age 7.8 yrs, range 0.7-17.9 yrs; 35 [66%] male; 46 [87%] black and 7 [13%] white) were admitted to the pediatric intensive care unit during the study period. Fifteen (28%) patients developed metabolic acidosis with hyperventilation (pH 120 mg/dL [6.7 mmol/L]). Patients who developed metabolic acidosis with hyperventilation received asthma therapy similar to that received by patients who did not develop the disorder. Metabolic acidosis resolved contemporaneously with tapering of beta2-adrenergic agonists and administration of supportive care. All patients survived. Metabolic acidosis with hyperventilation manifesting as respiratory distress can occur in children with severe acute asthma. A pathophysiologic rationale exists for the contribution of beta2-adrenergic agents to the development of this acid-base disorder. Failure to recognize metabolic acidosis as the underlying mechanism of respiratory distress may lead to inappropriate intensification of bronchodilator therapy. Supportive care and tapering of beta2-adrenergic agents are recommended to resolve this condition.

    Neutrophil to lymphocyte ratio (NLR) serves as a powerful inflammatory marker for predicting cardiovascular events. Here, we investigate whether admission NLR is associated with hematoma volume, stroke severity, and 3-month outcomes in patients with acute intracerebral hemorrhage (ICH). 352 patients with acute ICH were prospectively identified in this study. Demographic characteristics, lifestyle risk factors, NIHSS score, hematoma volumes, and other clinical features were recorded for all participants. Patients was divided into quartiles based on the admission NLR levels (Q1: hematoma volume, admission severity, or the outcomes after ICH. Median NIHSS scores for each quartile (Q1 to Q4) were 6.0, 6.0, 6.0, and 11.0 (P=.001), and median hematoma volumes were 9.5, 9.3, 9.1, and 15.0ml (P=.005), respectively. After adjusting the age, sex, and other potential risk factors, the patients in Q4 had higher NIHSS scores (P=.042) and larger hematoma volume (P=.014). After 3-month follow-up, 148 poor outcomes (mRS, 3-6) and 47 all-cause deaths were documented. There were more patients with poor outcomes in Q4 than Q1. However, compared with the patients in Q1, those in Q4 were not associated with poor outcomes (P-trend=0.379), and all-cause mortality (P-trend=0.843) after adjust for other risk factors. Higher admission NLR are associated with larger hematoma volume and more serious stroke, but not 3-month outcomes in patients with acute ICH. Copyright © 2016 Elsevier Inc. All rights reserved.

    Paracetamol (acetaminophen) hepatotoxicity is the commonest cause of acute liver failure (ALF) in the UK. Conflicting data regarding the outcomes of paracetamol-induced ALF resulting from different overdose patterns are reported. Using prospectively defined criteria, we have analysed the impact of overdose pattern upon outcome in a cohort of 938 acute severe liver injury patients admitted to the Scottish Liver Transplantation Unit. Between 1992 and 2008, 663 patients were admitted with paracetamol-induced acute severe liver injury. Of these patients, 500 (75.4%) had taken an intentional paracetamol overdose, whilst 110 (16.6%) had taken an unintentional overdose. No clear overdose pattern could be determined in 53 (8.0%). Unintentional overdose patients were significantly older, more likely to abuse alcohol, and more commonly overdosed on compound narcotic/paracetamol analgesics compared with intentional overdose patients. Unintentional overdoses had significantly lower admission paracetamol and alanine aminotransferase concentrations compared with intentional overdoses. However, unintentional overdoses had greater organ dysfunction at admission, and subsequently higher mortality (unintentional 42/110 (38.2%), intentional 128/500 (25.6%), P overdoses (77.8%, 95% confidence intervals (CI) 62.9, 88.8) compared with intentional overdoses (89.9%, 95% CI 83.4, 94.5). Unintentional overdose was independently predictive of death or liver transplantation on multivariate analysis (odds ratio 1.91 (95% CI 1.07, 3.43), P = 0.032). Unintentional paracetamol overdose is associated with increased mortality compared with intentional paracetamol overdose, despite lower admission paracetamol concentrations. Alternative prognostic criteria may be required for unintentional paracetamol overdoses. © 2011 The Authors. British Journal of Clinical Pharmacology © 2011 The British Pharmacological Society.

    Full Text Available Abdominal compartment syndrome (ACS in patients with severe acute pancreatitis (SAP is a marker of severe disease. It occurs as combination of inflammation of retroperitoneum, visceral edema, ascites, acute peripancreatic fluid collections, paralytic ileus, and aggressive fluid resuscitation. The frequency of ACS in SAP may be rising due to more aggressive fluid resuscitation, a trend towards conservative treatment, and attempts to use a minimally invasive approach. There remains uncertainty about the most appropriate surgical technique for the treatment of ACS in SAP. Some unresolved questions remain including medical treatment, indications, timing, and interventional techniques. This review will focus on interventional treatment of this serious condition. First line therapy is conservative treatment aiming to decrease IAP and to restore organ dysfunction. If nonoperative measures are not effective, early abdominal decompression is mandatory. Midline laparostomy seems to be method of choice. Since it carries significant morbidity we need randomized studies to establish firm advantages over other described techniques. After ACS resolves efforts should be made to achieve early primary fascia closure. Additional data are necessary to resolve uncertainties regarding ideal timing and indication for operative treatment.

    We discuss the importance of Contrast-Enhanced CT (C.E.CT) in establishing the variety of the intracranial pathological process in acute severe head injuries. During a two-and-a-half-year period (June, 1977 - December, 1979) thirty-three patients with acute severe head injuries were autopsied, all of whom had been scanned on admission. Among them, 14 patients had undergone both plain CT and C.E.CT on admission. Brain slices were examined macroscopically in three categories; brain contusion, subarachnoid hemorrhage, and intracerebral hemorrhage. Each category was then compared retrospectively with the plain CT and C.E.CT findings. C.E.CT was found to correspond much better to the autopsy finding than plain CT in the following three points: (1) C.E.CT clearly enhances the contusion areas and reveals occult contusion areas. (2) C.E.CT enhances the areas corresponding to the subarachnoid space due to the breakdown of brain-surface blood vessels. (3) C.E.CT reveals the enlargement and formation of the intracerebral hematoma by the extravasation of the intravenous contrast material from injured arterial vessels. (author)

    The pre-dietary rehabilitation levels of acute phase proteins (APP) namely, alpha-1-antitrypsin (AAT), orosomucoid (ORO), haptoglobin (HAP), fibrinogen (FIB) and C-reactive protein (CRP) in the plasma of Sudanese children with severe protein energy malnutrition (PEM) were compared with those of normal controls, and with the levels after dietary rehabilitation. Eighty one children were included in the study; 49 with severe PEM (23 with marasmus, 17 with marasmic-kwashiorkor and 9 with kwashiorkor), 13 with tuberculosis (TB) and 19 healthy children as controls. The study showed a high incidence of infections, especially acute respiratory infection (ARI), diarrhoeal diseases and intestinal parasites in the malnourished children. The mean plasma level of albumin was significantly lower in the malnourished children compared to controls (P<0.001), with kwashiorkor children showing the lowest mean level. This hypoalbuminaemia was significantly associated with the presence of ARI and intestinal parasites. The mean plasma levels of the APP, except FIB, were significantly higher in malnourished children than in controls, with higher levels associated with ARI and the presence of fever. Malnourished children with TB had significantly higher mean levels of the APP (AAT, HAP, FIB, CRP) compared to those without TB. The mean levels of HAP and AAT were significantly lower in the presence of diarrhoea, suggesting their loss in the stool. The mean levels of the APP after two weeks dietary rehabilitation and antimicrobial treatment showed a significant drop in only two of the APP, namely CRP, ORO, while FIB showed a significant rise.

    Computed tomography (CT) and an evaluating of the degree of severity in patients with severe acute pancreatitis (SAP) are required to decide the therapeutic strategy. We measured blood interleukin-6 (IL-6) in critically ill patients at our intensive care unit (ICU) in a daily clinical setting. To determine the significance of grading CT findings in SAP, we studied the correlation between CT grading and blood IL-6 in SAP patients on ICU admission. Among 31 SAP cases, 66 were CT grade III, 22 CT grade IV, and 3 cases CT grade V. Patients with a higher CT grade tended to have higher blood IL-6. Data also showed that mean blood IL-6 among SAP patients in stage 2 was significantly higher than that among those in stage 3 (p<0.05). From these results, we concluded that CT grading and IL-6 blood level have a different significance in the management of SAP patients. (author)

  18. Acute promyelocytic leukemia with JAK2 V617F and severe differentiation syndrome

    Full Text Available Myeloproliferative neoplasms transformed into AML usually have a poor prognosis. We report a case of essential thrombocythemia with myelofibrosis that transformed into acute promyelocytic leukemia (APL with both the t(15;17 translocation as well as the JAK2 V617F mutation. Clinically, this case was notable for severe differentiation syndrome despite treatment with high-dose dexamethasone. Cytokine production by differentiating APL cells was not directly abrogated by JAK2 inhibitors in vitro, suggesting that JAK2 V617F enhances the hyperinflammatory response downstream of cytokines. JAK1/2 inhibitors may therefore dampen the inflammatory cascade downstream of cytokine production, similar to glucocorticoids, and have a role in treating severe differentiation syndrome.

    Pharmacological properties of the sufentanil sublingual tablet 30mcg (SST 30mcg) could offer potential analgesic advantages in settings requiring noninvasive, acute pain management. The feasibility of using SST 30mcg for moderate-to-severe pain management in the emergency department (ED) was evaluated. This open-label, multicenter feasibility study included patients aged ≥18years who presented to the ED with moderate-to-severe pain (≥4 on the numeric rating scale of pain intensity (NRS); opioid-tolerant patients were excluded. Patients received a single SST 30-mcg dose (single-dose cohort) or, upon request, ≤3 additional doses ≥60min apart (multiple-dose cohort) and were evaluated over 1 or 2h. Effectiveness was assessed by patient-reported pain scores (11-point NRS; 5-point pain relief scale). Safety and tolerability were also assessed. Overall, 76 patients enrolled into the single-dose (n=40) and multiple-dose (n=36) cohorts. In the first hour (combined cohorts), mean pain intensity was significantly lower 15-min post-dosing (P<0.001; clinically meaningful within 30-minutes post-dosing) and continued to decrease during the first hour (P<0.001 for each 15-minute interval). Mean pain intensity (multiple-dose cohort) decreased from 7.6 at baseline to 4.5 at 1h and to 4.6 at 2h (P<0.001 for both); mean pain relief increased from baseline to 1.9 at 1h (P<0.001) and to 2.0 at 2h (P<0.001). Most (79%) patients had no adverse events (AEs), and there were no severe AEs. SST 30mcg was feasible for managing moderate-to-severe acute pain in an ED setting. Copyright © 2017 The Authors.

    Severe acute pancreatitis is associated with significant morbidity/mortality; thus, the ability to predict hospital course is imperative. An updated version of the Acute Physiology and Chronic Health Evaluation II (APACHE), APACHE IV, has recently been validated. Unlike other versions, APACHE IV uses hepatobiliary parameters and accounts for multiple comorbid conditions and sedation. The intention of this study was to examine APACHE IV for predicting mortality and secondary outcomes for pancreatitis in a prospective cohort. In addition, we compared APACHE IV to APACHE II, Bedside Index for Severity in Acute Pancreatitis, and Ranson criterion. We prospectively collected physiologic parameters for each scoring system in 266 patients with severe acute pancreatitis from August 2011 to April 2014. Prognostic value of each score was determined using the area under the receiver operating characteristic curve. Among 266 patients, 59% were men, 52% were white, and 36.5% had alcohol-induced pancreatitis. Mortality occurred in 15 (5.6%), and an APACHE IV of 44 or greater predicted mortality in 100% of cases. The receiver operating characteristic curve for APACHE IV was 0.93 (confidence interval [CI], 0.88-0.97); APACHE II, 0.87 (CI, 0.80-0.94); Bedside Index for Severity in Acute Pancreatitis, 0.86 (CI, 0.78-0.94); and Ranson criterion, 0.90 (CI, 0.94-0.96). The APACHE IV is a valid means for predicting mortality and disease-related complications in acute pancreatitis.

    Full Text Available Posthemorrhagic anemia is a rare but important cause of anemia in neonates, second only to hemolytic anemia of newborn. Most cases of posthemorrhagic anemia are reported from fetomaternal hemorrhage or umbilical cord accidents in utero. This case report describes a preterm infant who developed severe anemia and shock immediately after delivery related to an acute hemorrhage through patent umbilical cord vessels secondary to a tear in the umbilical cord at the site of cord clamping. We believe that umbilical cord bleeding from errors in cord clamping could be an important cause of acute blood loss in the delivery room and that it may result in significant clinical morbidity, especially in extremely premature infants.

  7. Permissive hypercapnia for severe acute respiratory distress syndrome in immunocompromised children: A single center experience.

    Full Text Available Controlled hypoventilation while accepting hypercapnia has been advocated to reduce ventilator-induced lung injury. The aim of the study was to analyze outcomes of a cohort of immunocompromised children with acute respiratory distress syndrome (ARDS ventilated with a strategy of stepwise increasing PCO2 targets up to 140 mm Hg.Retrospective analysis of outcomes of a cohort of children with oncologic disease or after stem cell transplantation and severe respiratory failure in comparison with a historical control cohort.Out of 150 episodes of admission to the PICU 88 children underwent invasive mechanical ventilation for >24h (overall survival 75%. In a subgroup of 38 children with high ventilator requirements the PCO2 target ranges were increased stepwise. Fifteen children survived and were discharged from the PICU. Severe pulmonary hypertension was seen in two patients and no case of cerebral edema was observed. Long term outcome was available in 15 patients and 10 of these patients survived without adverse neurological sequelae. With introduction of this strategy survival of immunocompromised children undergoing mechanical ventilation for >24h increased to 48% compared to 32% prior to introduction (historical cohort.A ventilation strategy incorporating very high carbon dioxide levels to allow for low tidal volumes and limited inspiratory pressures is feasible in children. Even severe hypercapnia may be well tolerated. No severe side effects associated with hypercapnia were observed. This strategy could potentially increase survival in immunocompromised children with severe ARDS.

    The aim of this study was to compare and validate the different classifications of severity in acute pancreatitis (AP) and to investigate which characteristics of the disease are associated with worse outcomes. AP is a heterogeneous disease, ranging from uneventful cases to patients with considerable morbidity and high mortality rates. Severity classifications based on legitimate determinants of severity are important to correctly describe the course of disease. A prospective multicenter cohort study involving patients with AP from 23 hospitals in Spain. The Atlanta Classification (AC), Revised Atlanta Classification (RAC), and Determinant-based Classification (DBC) were compared. Binary logistic multivariate analysis was performed to investigate independent determinants of severity. A total of 1655 patients were included; 70 patients (4.2%) died. RAC and DBC were equally superior to AC for describing the clinical course of AP. Although any kind of organ failure was associated with increased morbidity and mortality, persistent organ failure (POF) was the most significant determinant of severity. All local complications were associated with worse outcomes. Infected pancreatic necrosis correlated with high morbidity, but in the presence of POF, it was not associated to higher mortality when compared with sterile necrotizing pancreatitis. Exacerbation of previous comorbidity was associated with increased morbidity and mortality. The RAC and DBC both signify an advance in the description and differentiation of AP patients. Herein, we describe the complications of the disease independently associated to morbidity and mortality. Our findings are valuable not only when designing future studies on AP but also for the improvement of current classifications.

    Aluminum phosphide poisoning is common in our region. It can cause severe metabolic acidosis and persistent hypotension, which lead to cardiogenic shock and subsequently mortality. Oliguric or anuric acute kidney injury is seen in almost all patients with aluminum phosphide poisoning. Renal replacement therapies are recommended in these patients to improve metabolic acidosis and increase the rate of survival. We report 2 cases of severe acute aluminum phosphide poisoning treated successfully with peritoneal dialysis.

    To establish a clinical severity index that correlates severity of body system abnormalities with outcome in dogs with acute pancreatitis (AP) and determine the usefulness of serum C-reactive protein (C-RP) concentration as an objective measure of AP severity. Retrospective cohort study. 61 client-owned dogs with ultrasonographically or histologically confirmed AP. Medical records of AP-affected dogs were reviewed, and signalment, physical examination findings, clinicopathologic data, and outcome (death or discharge from the hospital) were evaluated. The correlation of specific abnormalities in endocrine, hepatic, renal, hematopoietic, cardiovascular, and respiratory systems; local pancreatic complications; and intestinal integrity were evaluated, and a clinical severity index was developed for AP in dogs. The severity index score was compared with outcome and, for 12 dogs, with serum C-RP concentration. The clinical severity index had a good correlation with outcome and interval from hospital admission until end point (days until outcome), but there was no difference in days until outcome between survivors and nonsurvivors. All 12 dogs evaluated had high serum C-RP concentration, but this variable was not related to outcome; however, within a 2-day period after onset of clinical signs, serum C-RP concentration in survivors and nonsurvivors differed significantly. Among AP-affected dogs, the clinical severity index may be useful for treatment comparisons and prediction of intensive management requirements. Serum C-RP concentration was best related to AP severity within a 2-day period after onset of clinical signs, but daily measurement may be more useful for monitoring progress.

    Severe acute pancreatitis is an inflammatory disease of the pancreas with a high morbidity and mortality. To date, no causal treatment is known. The aim of the present study was to analyze the impact of pancreatic microcirculatory disturbances in severe acute pancreatitis and to correlate the effects with histopathologic tissue damage and outcome. Severe acute pancreatitis was induced in 129 pigs by injection of glycodeoxycholic acid into the pancreatic duct. Pancreatic microcirculation, pancreatic tissue oxygenation, histopathologic tissue damage, and survival were measured and analyzed. Our study demonstrates a strong correlation between pancreatic microcirculatory disturbances and histopathologic tissue damage (r = 0.728; P pancreatitis according to an established porcine pancreatitis score (r = 0.694; P pancreatic microcirculation were shown to be associated with an increased mortality rate in severe acute pancreatitis. We found that pancreatic microcirculatory disturbances have significant effects on histopathologic tissue damage and the outcome of severe acute pancreatitis. For a better survival of severe acute pancreatitis, the treatment should focus on an improvement of pancreatic microcirculation.

    To evaluate the effects of disease severity and necrosis on organ dysfunctions in acute pancreatitis (AP). One hundred and nine patients treated as AP between March 2003 and September 2007 with at least 6 mo follow-up were included. Patients were classified according to severity of the disease, necrosis ratio and localization. Subjective clinical evaluation and fecal pancreatic elastase-I (FPE-I) were used for exocrine dysfunction evaluation, and oral glucose tolerance test was completed for endocrine dysfunction. The correlation of disease severity, necrosis ratio and localization with exocrine and endocrine dysfunction were investigated. There were 58 male and 51 female patients, and mean age was 56.5 ± 15.7. Of the patients, 35.8% had severe AP (SAP) and 27.5% had pancreatic necrosis. Exocrine dysfunction was identified in 13.7% of the patients [17.9% were in SAP, 11.4% were in mild AP (MAP)] and 34.7% of all of the patients had endocrine dysfunction (56.4% in SAP and 23.2% in MAP). In patients with SAP and necrotizing AP (NAP), FPE-Ilevels were lower than the others (P pancreatic head necrosis or near total necrosis, FPE-1 levels were lower than 200 μg/g stool. Forty percent of the patients who had undergone necrosectomy developed exocrine dysfunction. Endocrine dysfunction was more significant in patients with SAP and NAP (P pancreatic head necrosis and necrosectomy should be followed for pancreatic functions.

    Full Text Available Introduction: Xylitol is a sugar naturally found in various vegetables and fruits. Studies have demonstrated that the xylitol can be used as new preventive method for acute otitis media (AOM. Objective: To clarify the possible mechanisms of xylitol actions to inhibit the growth of otopathogenic bacteria and to describe researches that contribute for the discussion about the feasibility of the use of this sugar in the prevention of AOM. Method: Literature review based on scientific articles selected by means of the medical databases: MEDLINE, Cochrane, PubMed (MeSH and Web of Science. Results: Studies have demonstrated the efficacy of xylitol to prevent the AOM, when it is administered five times a day in chewing gum. However, this sugar is not so effective in the prevention of AOM during upper airways infections. Final Comments: Xylitol seems to be an effective strategy in prevention of acute otitis media. However, new studies are necessary to establish ideal doses, frequencies and vehicles for the correct administration of the sugar, which allows for its utilization in the public health system.

    Full Text Available The European population is only suboptimally supplied with the essential trace element selenium. Such a selenium status is supposed to worsen colitis while colitis-suppressive effects were observed with adequate or supplemented amounts of both organic selenomethionine (SeMet and inorganic sodium selenite. In order to better understand the effect of these selenocompounds on colitis development we examined colonic phenotypes of mice fed supplemented diets before the onset of colitis or during the acute phase. Colitis was induced by treating mice with 1% dextran sulfate sodium (DSS for seven days. The selenium-enriched diets were either provided directly after weaning (long-term or were given to mice with a suboptimal selenium status after DSS withdrawal (short-term. While long-term selenium supplementation had no effect on colitis development, short-term selenite supplementation, however, resulted in a more severe colitis. Colonic selenoprotein expression was maximized in all selenium-supplemented groups independent of the selenocompound or intervention time. This indicates that the short-term selenite effect appears to be independent from colonic selenoprotein expression. In conclusion, a selenite supplementation during acute colitis has no health benefits but may even aggravate the course of disease.

    Acute hemorrhagic leukoencephalitis (AHLE) is a rare and fulminant demyelinating disease considered to be the most severe form of acute disseminated encephalomyelitis (ADEM). A 70-year-old man was admitted to our emergency department (ED) after 1 week of unspecific abdominal symptoms and moderate fever in the first 3 days. Within the ED he developed a rapid onset coma and flaccid tetraparesis. Cerebrospinal fluid (CSF) analysis showed mild polymorphonuclear pleocytosis and magnetic resonance imaging (MRI) revealed supratentorial focal white matter lesions and diffuse involvement of the medulla and spinal cord. A presumptive diagnosis of ADEM was made and the patient was treated with corticosteroids followed by intravenous immunoglobulin. His neurological state did not improve and the MRI on day 8 after admission showed an increased number of lesions, mainly in the brainstem, with hemorrhagic foci. The patient died the following day and pathological features confirmed the diagnosis of AHLE. This is a unique presentation of a rare disease with detailed MRI characteristics and pathological confirmation. Although this condition is usually fatal, early recognition and aggressive therapeutic management can facilitate survival. Copyright © 2011 Wiley-Liss, Inc.

    Acute pancreatitis during pregnancy is a rare and dangerous disease. This study attempts to present a comprehensive analysis of severe acute pancreatitis (SAP) during pregnancy and to identify the factors associated with poor outcomes. This study was a retrospective review of the medical records of SAP patients during pregnancy consecutively admitted into the Research Institute of General Surgery from 1999 to 2010. Information was collected on presentation, management, and outcome. Eighteen patients were identified to have been diagnosed with SAP during pregnancy. Eleven patients (61.1%) were nulliparous; most attacks (88.9%) occurred during the third trimester. There were seven cases with preterm labor, six with fetal losses, and no maternal death. The etiology was biliary disease in seven patients (38.9%), hypertriglyceridemia in five patients (27.8%), both biliary and hypertriglyceridemia in four patients (22.2%), and idiopathic in two patients (11.1%). Patients with failure in more than one (≥2) organ were more likely to result in fetal loss (OR = 25, P = 0.016). SAP during pregnancy is predominantly biliary in etiology, but a significant proportion is caused by hypertriglyceridemia. Patients with failure in at least two organs result in relatively worse fetal outcomes.

    To explore the clinical efficacy of electroacupuncture intervention on severe acute pancreatitis (SAP) at early stage complicated with intestinal paralysis. Sixty-eight cases of SAP were randomly divided into observation group (48 cases) and control group (20 cases). In observation group, according to the course of sickness, the early-stage subgroup (30 cases, hospitalized in 3 d) and late-stage subgroup (18 cases, hospitalized in 3-7 d) were subdivided. In control group, the conventional treatment was applied. In observation group, based on the same treatment as control group, electroacupuncture was supplemented at Zhongwan (CV 12), Zusanli (ST 36), Neiguan (PC 6), Hegu (LI 4), etc. Acute physiology and chronic health evaluation (APACHE) II scores, the recovery time of intestinal paralysis and laboratory indices, complications, operation transfer rate, death rate and the admission time were compared among groups after treatment. The total effective rate was 83.3% (25/30) in early-stage subgroup, which was superior to 72.2% (13/18) in late-stage subgroup and 65.0% (13/20) in control group (P complications, operation transfer rate, death rate and admission time were all lower remarkably than those in late-stage subgroup and control group (P 0.05). The clinical efficacy of electroacupuncture intervention on SAP complicated with intestinal paralysis is superior remarkably to that of conventional treatment, and the efficacy of electroacupuncture intervention at early stage is better than that at late stage.

    Full Text Available Acute exogenous lipoid pneumonia is a rare disorder in adults. A treatment of choice for lipoid pneumonia has not been established, and systemic corticosteroid use remains controversial. We report the case of a 32-year-old man with schizophrenia who presented with kerosene-induced acute exogenous lipoid pneumonia that was treated with a systemic corticosteroid. In this case, supportive therapy did not improve the patient's condition, so systemic corticosteroid therapy was commenced four days after he ingested the kerosene. After corticosteroid commencement, the patient's symptoms and hypoxia improved within a few days. Although some radiological characteristics of this disorder have been reported previously, the process of radiological improvement of exogenous lipoid pneumonia is not well known. In this case, computed tomography findings changed dramatically after corticosteroid therapy was initiated. Extensive bilateral consolidations that were observed on admission improved. Although pneumatoceles developed two weeks after corticosteroid commencement, they were nearly gone after two months of the treatment. While corticosteroid therapy is not suitable for all cases, it should be considered for severe or refractory cases.

    Full Text Available Introduction. Early assessment of the severity and etiology of acute pancreatitis is very important for further treatment procedures. The aim of the study was to investigate the association between intra-abdominal pressure (IAP and procalcitonin as an indicator of severity of acute pancreatitis. Method. The IAP is measured every 12 hours through the urinary catheter placed in the bladder, in 65 patients with acute pancreatitis. Procalcitonin is measured within 24 hours of receipt of the patient, after 48 hours and after 78 hours. These values of procalcitonin and IAP were compared to each other and in relation to the Acute Physiology, Age and Chronic Health Evaluation II (APACHE II scoring system. Patients with APACHE II score > 8 are defined with moderate and severe acute pancreatitis. Results. The values of IAP (18,1 ± 4,5 mmHg vs 8,9 ± 2,67 mmHg; p = 0,01 , procalcitonin (15,43 + 2,25 ng/ml vs 3,14 + 1,12 ng/ml; p =0,031 and APACHE II scoring system (17,3 ± 6,24 vs 6,5 ± 1,0; p = 0,013 were significantly higher in patients with moderate and severe acute pancreatitis. The increase in the value of IAP was accompanied by an increase in the value of procalcitonin (r = 0,581, p = 0,01. The sensitivity in the prediction of severe acute pancreatitis after 24 hours of receiving the patient is 91,7% for the IAP, 87,8% for procalcitonin and 84,9% for APACHE II scoring system. Conclusion. The increase in the value of the IAP is accompanied by an increase in the values of procalcitonin, also patients with higher values of APACHE II scoring sys­tem have higher values of IAP and procalcitonin. The values of IAP and procalcitonin can be used as markers of acute pancreatitis severity.

    Based on this characteristic of fast reactor core, potential impact of CDA (Core Disruptive Accident) caused by ATWS has been considered as an important safety issue, although it is extremely unlikely. In order to prevent and mitigate the severe accident, the fast reactor core has been designed with various safety features. In this paper, as a part of study to develop the domestic regulatory requirements and guidelines related to SFR core safety, international trends on safety features which have been considered in current SFR cores are reviewed. In order to develop the regulatory requirements and guidelines related to a SFR core design for prevention of CDA, the core safety features were reviewed. The safety features considered in current SFR cores have a function that prevents to progress into next step in accident sequences. The trends on current safety features are as follows: · 'passive shutdown systems' to prevent initiating events such as ULOF, UTOP, ULOHS, etc · 'core designs with low void effect' to prevent the large void reactivity insertion in initiating phase · 'specific provisions for core with conventional positive void effect' to prevent the core recriticality in transition phase Consequently, in regulatory review requirements and guidelines developed for SFR, contents for not only reduction of positive void effect but also features to ensure the safety of overall system should be reflected

    2009-01-01

    In March and September 2009 the school shootings in Winnenden and Ansbach once again demonstrated the need for preventive approaches in order to prevent further offences in Germany. Due to the low frequency of such offences and the low specificity of relevant risk factors known so far, prediction and prevention seems difficult though. None the less, several preventive approaches are currently discussed. The present article highlights these approaches and their specific advantages and disadvantages. As school shootings are multicausally determined, approaches focussing only on single aspects (i.e. prohibiting violent computer games or further strengthening gun laws) do not meet requirements. Other measures such as installing technical safety devices or optimizing actions of police and school attendants are supposed to reduce harm in case of emergency. Instead, scientifically founded and promising preventive approaches focus on secondary prevention and for this purpose employ the threat assessment approach, which is widespread within the USA. In this framework, responsible occupational groups such as teachers, school psychologists and police officers are to be trained in identifying students' warning signs, judging danger of these students for self and others in a systematic process and initiating suitable interventions.

    Background and Purpose Stroke imposes a major burden on patients, their families, and the national healthcare system. The purpose of this study was to determine the itemized hospital charges in acute ischemic stroke patients according to their severity by partitioning the charges in detail and then examining whether stroke severity was a significant contributor to these charges. Methods This study analyzed data of first-time acute ischemic stroke patients who had been admitted to an academic medical center between September 2003 and April 2009. The patients' demographic and clinical characteristics were analyzed descriptively, and then eight categorized hospital charges as well as the total charge were compared among patients grouped according to stroke severity, using analysis of variance. Multiple regression analyses were conducted to test the influence of stroke severity on itemized hospital charges as well as the total charge, while controlling for other related factors. Results More-severe strokes were associated with a higher total charge. Significantly higher charges were associated with patients with more-severe strokes regarding all charged items except imaging studies. The charges for imaging studies were similar across all severities of stroke. While controlling for other factors, a significant impact of stroke severity was found in both the total hospital charge and most itemized charges. Conclusions Itemized hospital charges for inpatients with acute ischemic stroke varied according to stroke severity. Stroke severity was a significant factor influencing the itemized charges of acute hospitalization of ischemic stroke patients. PMID:22523514

    Background: Computed tomographic pulmonary angiography (CTPA) has been established as a first-line test in the acute pulmonary embolism (APE) diagnostic algorithm, but the assessment of the severity of APE by this method remains to be explored. Purpose: To retrospectively evaluate right ventricular (RV) dysfunction and severity in patients with APE without underlying cardiopulmonary disease using helical computed tomography (CT). Material and Methods: Seventy-three patients (35 men and 38 women) were divided into two groups according to the clinical findings: severe APE (n=22) and non-severe APE (n=51). Pulmonary artery CT obstruction index was calculated according to the location and degree of clots in the pulmonary arteries. Cardiovascular parameters including RV short axis and left ventricular (LV) short axis, RV short axis to LV short axis (RV/LV) ratio, main pulmonary artery, azygous vein, and superior vena cava diameters were measured. Leftward bowing of the interventricular septum, reflux of contrast medium into the inferior vena cava and azygous vein, and bronchial artery dilatation were also recorded. The results were analyzed by Mann-Whitney U test, x2 test, Spearman's rank correlation coefficient, and the area under the receiver operating characteristic curve (Az). Results: CT obstruction index in patients with severe APE (median 43%) was higher than that of patients with non-severe APE (median 20%). Comparison of cardiovascular parameters between patients with severe and non-severe pulmonary embolism showed significant differences in RV short axis, LV short axis, RV/LV ratio, RV wall thickness, main pulmonary artery diameter, azygous vein diameter, leftward bowing of the interventricular septum, and bronchial artery dilatation. The correlation between CT obstruction indexes and cardiovascular parameters was significant. Spearman's rank correlation coefficient was highest between RV/LV ratio and CT obstruction index. Az values were significantly higher

    Immune-checkpoint inhibitors are emerging as revolutionary drugs for certain malignancies. However, blocking the co-inhibitory signals may lead to immune-related adverse events, mainly in the spectrum of autoimmune diseases including colitis, endocrinopathies and nephritis. Here, we report a case of a 75-year-old man with metastatic malignant melanoma treated with a combination of nivolumab (anti-PD1-antibody) and ipilimumab (anti-CTLA-4 antibody) who developed systemic rash along with severe acute tubulointerstitial nephritis after two doses of combination therapy. Kidney biopsy and peripheral blood immune profile revealed highly proliferative and cytotoxic T cell features. Herein, we discuss the pathophysiology and management of immune checkpoint blockade-related adverse events.

    Sewing machine oil ingestion is rare but is possible due to its availability at home. Chemically, it belongs to hydrocarbon family which is toxic if aspirated, owing to their physical properties such as high volatility and low viscosity. On the contrary, sewing machine lubricant has high viscosity and low volatility which makes it aspiration less likely. The main danger of hydrocarbon ingestion is chemical pneumonitis which may be as severe as acute respiratory distress syndrome (ARDS). We report a case of a 5-year-old girl with accidental ingestion of sewing machine lubricant oil, who subsequently developed ARDS refractory to mechanical ventilation. There was much improvement with airway pressure release ventilation mode of ventilation, but the child succumbed to death due to pulmonary hemorrhage.

    This report describes a case of severe hypernatremia with a serum sodium concentration of 188.1mmol/L caused by exogenous salt intake. A 26-year-old man diagnosed with Crohn's disease 5 years previously visited our clinic due to generalized edema and personality changes, with aggressive behavior. He had compulsively consumed salts, ingesting approximately 154 g of salt over the last 4 days. Despite careful fluid management that included not only hypotonic fluid therapy for 8 hours but also hypertonic saline administration, his serum sodium level decreased sharply at 40.6 mmol/L; however, it returned to normal within 72-hour of treatment without any neurological deficits. Primary hypothyroidism was also diagnosed. He was discharged after 9 days from admission, with a stable serum sodium level. We have described the possibility of successful treatment in a patient with hypernatremia caused by acute salt intoxication without sustained hypotonic fluid therapy.

    Diarrhea is common in patients with Crohn's disease and may be accompanied by acid base disorders, most commonly metabolic acidosis due to intestinal loss of bicarbonate. Here, we present a case of severe metabolic alkalosis in a young patient suffering from M. Crohn. The patient had undergone multiple resections of the intestine and suffered from chronic kidney disease. He was now referred to our clinic for recurrent acute kidney injury, the nature of which was pre-renal due to profound volume depletion. Renal failure was associated with marked hypochloremic metabolic alkalosis which only responded to high volume repletion and high dose blockade of gastric hypersecretion. Intestinal failure with stomal fluid losses of up to 5.7 litres per day required port implantation to commence parenteral nutrition. Fluid and electrolyte replacement rapidly improved renal function and acid base homeostasis. This case highlights the important role of gastrointestinal function to maintain acid base status in patients with Crohn's disease.

    BACKGROUND: Children with severe acute malnutrition (SAM) have increased requirements for phosphorus and magnesium during recovery. If requirements are not met, the children may develop refeeding hypophosphatemia and hypomagnesemia. However, little is known about the effect of current therapeutic...... diets (F-75 and F-100) on serum phosphate (S-phosphate) and magnesium (S-magnesium) in children with SAM. METHODS: Prospective observational study, with measurements of S-phosphate and S-magnesium at admission, prior to rehabilitation phase and at discharge in children aged 6-59 months admitted with SAM...... to Jimma Hospital, Ethiopia. Due to shortage of F-75, 25 (35 %) children were stabilized with diluted F-100 (75 kcal/100 ml). RESULTS: Of 72 children enrolled, the mean age was 32 ± 14 months, and edema was present in 50 (69 %). At admission, mean S-phosphate was 0.92 ± 0.34 mmol/L, which was low compared...

    The aim of this study was to determine the influence of severe acute hypoxia on muscle activation during whole body dynamic exercise. Eleven young men performed four incremental cycle ergometer tests to exhaustion breathing normoxic (FIO2=0.21, two tests) or hypoxic gas (FIO2=0.108, two tests). Surface electromyography (EMG) activities of rectus femoris (RF), vastus medialis (VL), vastus lateralis (VL), and biceps femoris (BF) were recorded. The two normoxic and the two hypoxic tests were averaged to reduce EMG variability. Peak VO2 was 34% lower in hypoxia than in normoxia (phypoxia than in normoxia in the RF and VM (phypoxia in RF, VL, and BF (phypoxia than in normoxia in VL (ppattern, which is adjusted depending on the FIO2 and the relative intensity of exercise. Both VL and VM are increasingly involved in power output generation with the increase of intensity and the reduction in FIO2.

    Thrombotic thrombocytopenic purpura (TTP) is a rare but potentially fatal condition. In women with a previous history of TTP there is increased risk of recurrence during pregnancy and the puerperium. There is some evidence that the risk of relapse during pregnancy is increased if the interval between the event and conception is short. We present a case in which pregnancy was achieved a few days after full recovery from an acute episode of severe acquired TTP (ADAMTS13 activity <0.1%) which was successfully treated with four courses of plasma exchange. There was no relapse of TTP during pregnancy and a healthy baby was delivered at term; the puerperium was uneventful. Copyright © 2016 Elsevier Ltd. All rights reserved.

  17. Legionella pneumonia associated with severe acute respiratory distress syndrome and diffuse alveolar hemorrhage - A rare association

    2017-01-01

    Full Text Available Legionella pneumophila is a common, usually underreported and undiagnosed cause of community acquired pneumonia which can lead to significant morbidity and mortality. Diffuse alveolar hemorrhage rarely have been associated with legionella infection. We present a 61-year-old man with hypertension, diabetes mellitus and obesity admitted with severe acute respiratory distress syndrome. He was found to have Legionella pneumonia with associated diffuse alveolar hemorrhage diagnosed with bronchoscopic sequential bronchoalveolar lavage. He was successfully managed with antibiotics, lung protective strategies and intravenous pulse dose steroids. This patient highlights the unusual association of Legionella infection and diffuse alveolar hemorrhage. Additionally, the case re-enforces the need for early and aggressive evaluation and management of patients presenting with pneumonia and progressive hypoxia despite adequate treatment.

    It is 10 years since severe acute respiratory syndrome (SARS) emerged, and East and Southeast Asia retain a reputation as a hot spot of emerging infectious diseases. The region is certainly a hot spot of socioeconomic and environmental change, and although some changes (e.g., urbanization and agricultural intensification) may reduce the probability of emerging infectious diseases, the effect of any individual emergence event may be increased by the greater concentration and connectivity of livestock, persons, and products. The region is now better able to detect and respond to emerging infectious diseases than it was a decade ago, but the tools and methods to produce sufficiently refined assessments of the risks of disease emergence are still lacking. Given the continued scale and pace of change in East and Southeast Asia, it is vital that capabilities for predicting, identifying, and controlling biologic threats do not stagnate as the memory of SARS fades.

    2017-11-01

    The Spanish IBD Registry (ENEIDA) is reporting in this issue of the Journal on a retrospective assessment of outcomes of cyclosporine use and infliximab use to treat steroid refractory acute severe ulcerative colitis (SR-ASUC) between 1989 and 2013. Overall, they found similar outcomes in terms of 3 month and 1 year colectomy rates. Serious adverse events were lower in cyclosporine users. While this study does not meet the standard of a prospective randomized controlled trial, it does remind us that cyclosporine can be effective in (SR-ASUC) and should be considered in those who have already failed antibody to tumor necrosis factor therapy or as a bridge to immunomodulators that have a slower onset of action.

    A toddler presented with poor appetite, weight loss and frequent respiratory tract infections for the past 6 months, fever and increasing paleness for the past 2 months and bilateral pedal oedema for the past 1 month. Anthropometry confirmed severe acute malnutrition. Clinical and laboratory evaluation revealed that the child also had hypopigmented hair and skin, splenohepatomegaly, pancytopenia and hypoalbuminaemia. The coexistence of hypopigmentation and suspected low immunity prompted us to investigate the child's hair, peripheral blood smear and bone marrow. Hair under light microscopy showed evenly distributed, large melanin granules, suggestive of Chediak-Higashi syndrome (CHS). Peripheral blood smear and bone marrow aspirate examinations revealed abnormal large intracytoplasmic granules, which was diagnostic of CHS. The child's investigations revealed coexistent hemophagocytic lymphohistiocytosis, confirming the diagnosis of CHS in 'accelerated phase', which is fatal if not treated. The parents prematurely took the child home against medical advice, before definitive therapy could be instituted.

    Severe combined immunodeficiency (SCID) is a defect in the differentiation and function of T cells. An increased malignancy risk, mainly lymphatic malignancy, has been described in patients with SCID. We report a patient with X-linked SCID who developed acute myeloid leukemia, derived from the recipient with somatic NRAS mutation 4 months after cord blood transplantation (CBT). Loss of heterozygosity phenomenon of the recipient at 6q14 locus was observed at 2 months post-CBT and progressed to 6q deletion (6q-) chromosome abnormality. Somatic NRAS mutation was detected at 3 months post-CBT. Thus, 6q- and NRAS mutation were strongly associated with the leukemic transformation in our patient.

    This study aims to describe etiological agents, demographic details of patients, seasonality and underlying conditions among patients hospitalized due to viral severe acute respiratory infection (SARI) in Yemen. We carried out a retrospective descriptive analysis of data from January 2014 to December 2015. Nasopharyngeal swabs were taken from each patient for laboratory testing. A total of 1346 diagnostic specimens were tested, of which 733 (54%) were positive for influenza viruses. Influenza A(H3) and A(H1N1) pdm09 predominated. Respiratory syncytial virus (RSV) was reported predominantly among children (41%). Males (61%) were more affected than females. The median age was 1 year (range 0.5-94.0). The median length of hospitalization was 6 days. Chronic cardiovascular disease was the most commonly reported underlying condition, but 67% had no documented underlying disease. Respiratory viruses, particularly RSV, adenovirus and influenza, were commonly associated with hospitalization for SARI.

    2015-01-01

    The sufentanil sublingual tablet system (SSTS) is a novel patient-controlled analgesia (PCA) system that is pending approval from the US FDA for the management of moderate to severe acute pain in hospitalized patients. SSTS offers a noninvasive alternative to intravenous (iv.) PCA and optimized on-demand analgesia with the rapid onset and titratibility of sublingual sufentanil. Phase III clinical trials have demonstrated that SSTS has greater efficacy for the treatment of pain during the 72-h postoperative period after open abdominal and major orthopedic (total knee or total hip arthroplasty) surgery compared with iv. PCA with morphine sulfate (MS) or a placebo system. Safety assessments indicate that adverse events are typical for postoperative patients taking opioid analgesics. While the frequency of adverse events is comparable between patients using SSTS and iv. PCA MS, the incidence of oxygen desaturation is lower in those using SSTS.

    Study on the action mechanism of inflammatory mediators generated by the severe acute pancreatitis (SAP) in multiple organ injury is a hotspot in the surgical field. In clinical practice, the main complicated organ dysfunctions are shock, respiratory failure, renal failure, encephalopathy, with the rate of hepatic diseases being closely next to them. The hepatic injury caused by SAP cannot only aggravate the state of pancreatitis, but also develop into hepatic failure and cause patient death. Its complicated pathogenic mechanism is an obstacle in clinical treatment. Among many pathogenic factors, the changes of vasoactive substances, participation of inflammatory mediators as well as OFR (oxygen free radical), endotoxin, etc. may play important roles in its progression.

    The pre-dietary rehabilitation levels of acute phase proteins (APP) namely, alpha-1-antitrypsin (AAT), orosomucoid (ORO), haptoglobin (HAP), fibrinogen (FIB) and C-reactive protein (CRP) in the plasma of Sudanese children with severe protein energy malnutrition (PEM) were compared with those of normal controls, and with the levels after dietary rehabilitation. Eighty one children were included in the study; 49 with severe PEM (23 with marasmus, 17 with marasmic-kwashiorkor and 9 with kwashiorkor), 13 with tuberculosis (TB) and 19 healthy children as controls. The study showed a high incidence of infections, especially acute respiratory infection (ARI), diarrhoeal diseases and intestinal parasites in the malnourished children. The mean plasma level of albumin was significantly lower in the malnourished children compared to controls (P<0.001), with kwashiorkor children showing the lowest mean level. This hypoalbuminaemia was significantly associated with the presence of ARI and intestinal parasites. The mean plasma levels of the APP, except FIB, were significantly higher in malnourished children than in controls, with higher levels associated with ARI and the presence of fever. Malnourished children with TB had significantly higher mean levels of the APP (AAT, HAP, FIB, CRP) compared to those without TB. The mean levels of HAP and AAT were significantly lower in the presence of diarrhoea, suggesting their loss in the stool. The mean levels of the APP after two weeks dietary rehabilitation and antimicrobial treatment showed a significant drop in only two of the APP, namely CRP, ORO, while FIB showed a significant rise.

    Management of the abdominal compartment syndrome during severe acute pancreatitis by the open abdomen method is associated with considerable morbidity and resource utilization. Thus, the aim of this study was to evaluate the safety and efficacy of the ultrasound-guided percutaneous interventions and/or minimally invasive surgery in the treatment of abdominal compartment syndrome. Forty-four patients with severe acute pancreatitis were enrolled into a prospective study and treated according to the standard management protocol. Interventional and/or surgical management of abdominal compartment syndrome was employed in 6 (13.6%) cases. In the context of this study, we assessed the feasibility and effectiveness of subcutaneous fasciotomy of the anterior m. rectus abdominis sheath, as well as the role of ultrasound-guided drainage of intra-abdominal and peripancreatic fluid collections in the management of abdominal compartment syndrome. Subcutaneous fasciotomy of the anterior m. rectus sheath and ultrasound-guided drainage of intra-abdominal and peripancreatic fluid collections seem to be safe (minor risk of bleeding or infection, closed abdomen, and easy care for the patient) and effective (resulted in a sustained decrease of intra-abdominal pressure to 13-16 mm Hg and regression of organ failures after intervention). Subcutaneous anterior m. rectus fasciotomy may appear to be beneficial in case of refractory abdominal compartment syndrome avoiding morbidity associated with the open abdomen technique. Both the subcutaneous fasciotomy and ultrasound-guided drainage of intra-abdominal and/or peripancreatic fluid collections seem to be safe and effective alternatives in the management of abdominal compartment syndrome; however, prospective studies are needed to further evaluate their clinical role.

    We present an updated cost analysis to provide new estimates of the cost of providing community-based treatment for severe acute malnutrition, including expenditure shares for major cost categories. We calculated total and per child costs from a provider perspective. We categorized costs into three main activities (outpatient treatment, inpatient treatment, and management/administration) and four cost categories within each activity (personnel; therapeutic food; medical supplies; and infrastructure and logistical support). For each category, total costs were calculated by multiplying input quantities expended in the Médecins Sans Frontières nutrition program in Niger during a 12-month study period by 2015 input prices. All children received outpatient treatment, with 43% also receiving inpatient treatment. In this large, well-established program, the average cost per child treated was €148.86, with outpatient and inpatient treatment costs of €75.50 and €134.57 per child, respectively. Therapeutic food (44%, €32.98 per child) and personnel (35%, €26.70 per child) dominated outpatient costs, while personnel (56%, €75.47 per child) dominated in the cost of inpatient care. Sensitivity analyses suggested lowering prices of medical treatments, and therapeutic food had limited effect on total costs per child, while increasing program size and decreasing use of expatriate staff support reduced total costs per child substantially. Updated estimates of severe acute malnutrition treatment cost are substantially lower than previously published values, and important cost savings may be possible with increases in coverage/program size and integration into national health programs. These updated estimates can be used to suggest approaches to improve efficiency and inform national-level resource allocation. © 2016 John Wiley & Sons Ltd.

    Purpose: Severe acute toxicity limits the effective use of radiotherapy in patients who are radiosensitive, and it is not usually possible to identify these radiohypersensitive (R-H) individuals before treatment commences. Five such R-H patients were detected over a 3-year period. We undertook this study to determine whether the severe acute radiohypersensitivity of these five individuals showed any correlation with cellular and molecular parameters known to be abnormal in radiosensitivity-related syndromes such as ataxia-telangiectasia (A-T). Methods and Materials: Lymphoblastoid cells were isolated from fresh blood from the 5 R-H individuals who had previously demonstrated clinical R-H at least 9 months prior to sampling. Lymphoblastoid cell lines (LCLs) were established to determine the extent of postradiation chromosomal aberrations, cell cycle delay, cell proliferation, and tumor suppressor p53 protein stabilization. The polymerase chain reaction (PCR) and protein truncation (PTT) assays were used to test for the possibility of mutations in the gene mutated in A-T, termed ATM. Results: LCLs derived from R-H subjects retained a significantly higher degree of radiation-induced chromosomal aberrations when compared to normal control LCLs. p53 stabilization by ionizing radiation appeared normal in all but one R-H subject. There was no evidence of A-T gene truncation mutations in any of the R-H subjects tested. Conclusions: All R-H subjects in this study had their cellular radiosensitivity confirmed by the chromosomal aberration assay. Delayed p53 stabilization at 4 hours postirradiation in one R-H subject suggested that different etiologies may apply in the radiohypersensitivity investigated in this study

    Full Text Available Objective. To study the safety and efficacy of a clopidogrel loading dose in patients with moderate and severe acute ischemic strokes. Background. The safety of clopidogrel loading has been extensively investigated in patients with minor strokes and transient ischemic attacks. Methods. Acute ischemic stroke patients presenting consecutively to our center from 07/01/08 to 07/31/13 were screened. Clopidogrel loading was defined as at least 300 mg dose (with or without aspirin given within 6 hours of admission. We compared outcomes in patients with baseline NIHSS > 3 with and without clopidogrel loading. Results. Inclusion criteria were met for 1011 patients (43.6% females, 69.1% black, median age 63. Patients with clopidogrel loading had lower baseline NIHSS than patients who were not loaded (8 versus 9, p=0.005. The two groups had similar risk for hemorrhagic transformation (p=0.918 and symptomatic hemorrhage (p=0.599. Patients who were loaded had a lower rate of neurological worsening (38.9% versus 48.3%, p=0.031 and less in-hospital mortality (4.3% versus 13.4%, p=0.001 compared to those who were not loaded. The likelihood of having a poor functional outcome did not differ between the two groups after adjusting for NIHSS on admission (OR = 0.71, 95% CI 0.4633–1.0906, p=0.118. Conclusion. Clopidogrel loading dose was not associated with increased risk for hemorrhagic transformation or symptomatic intracranial hemorrhage in our retrospective study and was associated with reduced rates of neuroworsening following moderate and severe stroke.

    Full Text Available ObjectiveTo study the change in serum CRP level in patients with severe acute pancreatitis (SAP, and to explore its clinical significance in predicting outcomes and assessing the severity of SAP. MethodsA retrospective analysis was performed on 52 SAP patients with complete case data and admitted to General Hospital of Shenyang Military Area Command from September 2013 to September 2014. Blood drawing was performed and serum CRP concentration was determined on admission and at 24, 48, 72, 96, 120, and 144 hours after admission. The pattern of its dynamic change was observed. ResultsSerum CRP level in SAP patients significantly increased, and had a positive correlation with clinical outcomes. Forty-two cases (80.77% gradually recovered with aggressive treatment and the serum CRP levels were also slowly reduced (P<0.05. The serum CRP levels in four death cases (7.7% had no significant decrease and was maintained at a high level (P<0.05. Six patients (11.53% had aggravated conditions and recovered after aggressive treatment; meanwhile, the serum CRP levels first increased and then decreased (P<0.05. ConclusionFor SAP patients, serum CRP level fluctuates as their conditions change and can be considered as an important reference index for evaluating the severity and judging the outcomes of SAP.

    The severe acute respiratory syndrome (SARS) coronavirus encodes several RNA-processing enzymes that are unusual for RNA viruses, including Nsp15 (nonstructural protein 15), a hexameric endoribonuclease that preferentially cleaves 3' of uridines. We solved the structure of a catalytically inactive mutant version of Nsp15, which was crystallized as a hexamer. The structure contains unreported flexibility in the active site of each subunit. Substitutions in the active site residues serine 293 and proline 343 allowed Nsp15 to cleave at cytidylate, whereas mutation of leucine 345 rendered Nsp15 able to cleave at purines as well as pyrimidines. Mutations that targeted the residues involved in subunit interactions generally resulted in the formation of catalytically inactive monomers. The RNA-binding residues were mapped by a method linking reversible cross-linking, RNA affinity purification, and peptide fingerprinting. Alanine substitution of several residues in the RNA-contacting portion of Nsp15 did not affect hexamer formation but decreased the affinity of RNA binding and reduced endonuclease activity. This suggests a model for Nsp15 hexamer interaction with RNA.

    Acute appendicitis (AA) is a common indication for urgent abdominal surgery. CA-125 glycoprotein antigen is a non-specific marker for epithelial ovarian cancer; CA-125 serum levels also increased in the conditions of peritoneal inflammation. The aim of this study was to examine the correlation between serum CA-125 levels and AA. All emergency department (ED) patients with suspected AA were prospectively enrolled in the study. The serum level of CA-125 was checked in every patient on arrival to the ED in addition to the routine clinical and laboratory evaluation. Data regarding demographic, clinical, radiological, operative and pathological features were analysed. One hundred consecutive patients (48 males) were enrolled in the study. We found a statistically significant correlation between CA-125 levels in males and the severity of appendicitis as described in the operative and pathology reports (P = 0.008 and P = 0.02, respectively). In addition, we observed a trend towards higher levels of CA-125 in males with AA compared with males without AA (9.9 ± 4.7 versus 7.8 ± 3.2 U/mL, respectively; P = 0.09). CA-125 levels correlate with the severity of appendicitis in males and may serve as a surrogate marker for the severity of other intra-abdominal surgical diseases. © 2015 Royal Australasian College of Surgeons.

    Full Text Available Background. Beside greater susceptibility to infections, acute graft host disease is a consequence of the activation of donor T-cells against host antigens. Most common target organs are skin, liver and intestinal mucosis.Methods. In the 6-year period between January 1995 and December 2000, 49 patients were treated with allogeneic haematopoietic stem cell transplantation (allo-HSCT in Transplant unit, Department of Hematology, Clinical Centre Ljubljana. The standard GVHD prophylaxis regimen consisted of cyclosporine and short-course methotrexate. Severe, grade III-IV aGVHD with skin and/or gastrointestinal and/or liver involvement appeared in 16 (32% of the 49 patients.Results. Among the 16 patients with severe aGVHD, 14 had liver involvement, ten gastrointestinal and eight skin involvement. One patient had skin involvement only, the rest of them had combined involvement of two or three organ systems. Routine first-line treatment for aGVHD, given to all 16 pts with severe forms of the disease, was methylprednisolone (MP 2mg/ kg. Six patients with predominant skin involvement responded to MP. Other ten patients with mainly liver and gastrointestinal involvement needed second or even third line aGVHD treatment. These were anti-thymocyte globulin (ATG and/or monoclonal antibodies (OKT3 and/or mycophenolate mofetil (MMF and/or FK506 (tacrolimus. Seven patients died of advanced aGVHD and treatment related infection.Conclusions. Based on our experiences, we conclude that in critically ill patients with severe aGVHD, neutropenia and high risk for opportunistic infection, each day of ineffective MP therapy may have fatal consequences. Simultaneous institution of a combination of corticosteroids and a second-line drug might prove more appropriate for patients with a severe form of aGVHD.

    Acute otitis media (AOM) is the most common bacterial infection among young children in the United States. There are limitations and concerns over its treatment with antibiotics and surgery and so effective preventative measures are attractive. A potential preventative measure is xylitol, a natural sugar substitute that reduces the risk of dental decay. Xylitol can reduce the adherence of Streptococcus pneumoniae (S pneumoniae) and Haemophilus influenzae (H influenzae) to nasopharyngeal cells in vitro. This is an update of a review first published in 2011. To assess the efficacy and safety of xylitol to prevent AOM in children aged up to 12 years. We searched CENTRAL (to Issue 12, 2015), MEDLINE (1950 to January 2016), Embase (1974 to January 2016), CINAHL (1981 to January 2016), LILACS (1982 to January 2016), Web of Science (2011 to January 2016) and International Pharmaceutical Abstracts (2000 to January 2016). Randomised controlled trials (RCTs) or quasi-RCTs of children aged 12 years or younger where xylitol supplementation was compared with placebo or no treatment to prevent AOM. Two review authors independently selected trials from search results, assessed and rated study quality and extracted relevant data for inclusion in the review. We contacted trial authors to request missing data. We noted data on any adverse events of xylitol. We extracted data on relevant outcomes and estimated the effect size by calculating risk ratio (RR), risk difference (RD) and associated 95% confidence intervals (CI). We identified five clinical trials that involved 3405 children for inclusion. For this 2016 update, we identified one new trial for inclusion. This trial was systematically reviewed but due to several sources of heterogeneity, was not included in the meta-analysis. The remaining four trials were of adequate methodological quality. In three RCTs that involved a total of 1826 healthy Finnish children attending daycare, there is moderate quality evidence that

    The Pinus densiflora leaf has been traditionally used to treat mental health disorders as a traditional Chinese medicine. Here we examined the ethnopharmacological relevance of pine needle on memory impairment caused by stress. To elucidate the possible modulatory actions of 30% ethanolic pine needle extract (PNE) on stress-induced hippocampal excitotoxicity, we adopted an acute restraint stress mouse model. Mice were orally administered with PNE (25, 50, or 100mg/kg) or ascorbic acid (100mg/kg) for 9 days, and were then subjected to restraint stress (6h/day) for 3 days (from experimental day 7-9). To evaluate spatial cognitive and memory function, the Morris water maze was performed during experimental days 5-9. Restraint stress induced the memory impairment (the prolonged escape latency and cumulative path-length, and reduced time spent in the target quadrant), and these effects were significantly prevented by PNE treatment. The levels of corticosterone and its receptor in the sera/hippocampus were increased by restraint stress, which was normalized by PNE treatment. Restraint stress elicited the hippocampal excitotoxicity, the inflammatory response and oxidative injury as demonstrated by the increased glutamate levels, altered levels of tumor necrosis factor (TNF)-α and imbalanced oxidant-antioxidant balance biomarkers. Two immunohistochemistry activities against glial fibrillary acidic protein (GFAP)-positive astrocytes and neuronal nuclei (NeuN)-positive neurons supported the finding of excitotoxicity especially in the cornu ammonis (CA)3 region of the hippocampus. Those alterations were notably attenuated by administration of PNE. The above findings showed that PNE has pharmacological properties that modulate the hippocampal excitotoxicity-derived memory impairment under severe stress conditions.

    Assessment of prophylactic effect of Immunovac-VP-4 against acute respiratory diseases (ARDs) in collectives of children. Immunovac-VP-4 was used for prophylaxis of ARDs in communities of children (daycare centers, boarding school). During 3 consecutive controlled studies performed during peak incidence of epidemic influenza and ARD (1st study) and during pre-epidemic period (2nd and 3rd studies) the incidence of ARDs was studied in groups of vaccinated and non-vaccinated children. Criteria for assessment of ARDs incidence and their severity were as follows: number of ARD episodes per child, number of children with recurrent episodes of ARD during period of follow-up, duration of ARDs, and number of children with bacterial complications (bronchitis, otitis, etc.). Effect of intervention on immunologic parameters was assessed on levels of sIgA, IgG, IgA, and antibody titers in saliva. Schedule of vaccine administration was 3 daily intranasal and 6 - 9 oral administration of the vaccine with 3 - 4 days interval. Results of all three studies were virtually the same: decrease of number of ARD episodes and their duration; 3.1-fold reduction of number of children with recurrent infections during 14 months of follow-up, and 10.9--12-fold reduction during first 7 months of follow-up; decrease of bacterial complications rate (1.9% in children in intervention group, 11.9%--in control group). Increase of total immunoglobulin level and antibody titers to antigenic components of the vaccine from low baseline level was observed in saliva of vaccinated children. Immunovac-VP-4 results in enhanced and prolonged prophylactic effect on ARDs incidence and recommended for building of optimal system of prevention of polyetiologic complex of ARDs.

    Full Text Available BACKGROUND: Finding the most appropriate strategy for the prevention of moderate acute malnutrition (MAM and severe acute malnutrition (SAM in young children is essential in countries like Niger with annual "hunger gaps." Options for large-scale prevention include distribution of supplementary foods, such as fortified-blended foods or lipid-based nutrient supplements (LNSs with or without household support (cash or food transfer. To date, there has been no direct controlled comparison between these strategies leading to debate concerning their effectiveness. We compared the effectiveness of seven preventive strategies-including distribution of nutritious supplementary foods, with or without additional household support (family food ration or cash transfer, and cash transfer only-on the incidence of SAM and MAM among children aged 6-23 months over a 5-month period, partly overlapping the hunger gap, in Maradi region, Niger. We hypothesized that distributions of supplementary foods would more effectively reduce the incidence of acute malnutrition than distributions of household support by cash transfer. METHODS AND FINDINGS: We conducted a prospective intervention study in 48 rural villages located within 15 km of a health center supported by Forum Santé Niger (FORSANI/Médecins Sans Frontières in Madarounfa. Seven groups of villages (five to 11 villages were allocated to different strategies of monthly distributions targeting households including at least one child measuring 60 cm-80 cm (at any time during the study period whatever their nutritional status: three groups received high-quantity LNS (HQ-LNS or medium-quantity LNS (MQ-LNS or Super Cereal Plus (SC+ with cash (€38/month [US$52/month]; one group received SC+ and family food ration; two groups received HQ-LNS or SC+ only; one group received cash only (€43/month [US$59/month].

    To study the long-term use of self-study material in type 1 diabetes patient education targeted at the prevention of severe hypoglycaemia. Randomized 1:1:1 control study in three local hospitals. We studied 332 type 1 diabetes patients from the geographic population, aged 2.6-18.9 y at entry. The intervention group received a videotape and brochure in which interviewed patients, parents and medical experts reviewed in detail practical skills for self-control and treatment, with the aim of preventing severe hypoglycaemia. There were two control groups: one received a videotape and brochure with general diabetes information and the other only traditional treatment. Primary endpoints were severe hypoglycaemia needing assistance by another person and HbA1c. Dissemination, reading/viewing level, patients' attitudes and extra contact with caregivers were also investigated. At 24 mo, 249 subjects provided data. The yearly incidence of severe hypoglycaemia decreased at 24 mo from 42% to 25% (difference 17%, 95% CI 3-31, p = 0.0241) in the intervention group, but not in controls. HbA1c remained unchanged. Video use during months 13-24 was higher in the intervention group than in controls (p = 0.0477), ranging from 1-15 (median 2) times, among 37% of patients (months 1-12, 100%).

    Severe acute pancreatitis is a common critical disease, which may cause severe complications such as sepsis and multiple organ dysfunction syndrome (MODS), and has a high mortality. A 31-year-old woman with 25-weeks pregnancy presented with hyperlipidemic pancreatitis, sepsis and MODS. Based on conventional treatment, 125 h of continuous veno-venous hemofiltration (CVVH) and 3 sessions of hemoperfusion (HP) were carried out. The treatment turned out to be very successful. We suggest that early intervention by blood purification therapy, and CVVH combined with HP could be effective in severe acute pancreatitis.

    Hyperglycemia often occurs in severe burns; however, the underlying mechanisms and importance of managing postburn hyperglycemia are not well recognized. This study was designed to investigate the dynamic changes of postburn hyperglycemia and the underlying mechanisms and to evaluate whether early glycemic control is beneficial in severe burns. Prospective, randomized experimental study. Animal research laboratory. Sprague-Dawley rats. Anesthetized rats were subjected to a full-thickness burn injury comprising 40% of the total body surface area and were randomized to receive vehicle, insulin, and a soluble form of receptor for advanced glycation endproducts treatments. An in vitro study was performed on cultured H9C2 cells subjected to vehicle or carboxymethyllysine treatment. We found that blood glucose change presented a distinct pattern with two occurrences of hyperglycemia at 0.5- and 3-hour postburn, respectively. Acute insulin resistance evidenced by impaired insulin signaling and glucose uptake occurred at 3-hour postburn, which was associated with the second hyperglycemia and positively correlated with mortality. Mechanistically, we found that serum carboxymethyllysine, a dominant species of advanced glycation endproducts, increased within 1-hour postburn, preceding the occurrence of insulin resistance. More importantly, treatment of animals with soluble form of receptor for advanced glycation endproducts, blockade of advanced glycation endproducts signaling, alleviated severe burn-induced insulin resistance. In addition, early hyperglycemic control with insulin not only reduced serum carboxymethyllysine but also blunted postburn insulin resistance and reduced mortality. These findings suggest that severe burn-induced insulin resistance is partly at least mediated by serum advanced glycation endproducts and positively correlated with mortality.

    Purpose: Acute radiation proctitis is the most relevant complication of pelvic radiation and is still mainly treated supportively. Considering the negative impact of acute proctitis symptoms on patients' daily activities and the potential relationship between the severity of acute radiation injury and late damage, misoprostol was tested in the prevention of acute radiation-induced proctitis. Methods and Materials: A total of 100 patients who underwent radiotherapy for prostate cancer were entered into this phase III randomized, placebo-controlled, double-blind study with misoprostol or placebo suppositories. Radiation-induced toxicity was evaluated weekly during radiotherapy using the Common Toxicity Criteria. Results: Between the placebo and the misoprostol groups, no significant differences in proctitis symptoms occurred: 76% of patients in each group had Grade 1 toxicity, and 26% in the placebo group and 36% in the misoprostol group had Grade 2 toxicity. No differences were found in onset or symptom duration. Comparing the peak incidence of patients' toxicity symptoms, significantly more patients experienced rectal bleeding in the misoprostol group (p = 0.03). Conclusion: Misoprostol given as a once-daily suppository did not decrease the incidence and severity of radiation-induced acute proctitis and may increase the incidence of acute bleeding

    Severe forms of acute respiratory distress syndrome in patients with haematological diseases expose clinicians to specific medical and ethical considerations. We prospectively followed 143 patients with haematological malignancies, and whose lungs were mechanically ventilated for more than 24 h, over a 5-y period. We sought to identify prognostic factors of long-term outcome, and in particular to evaluate the impact of the severity of acute respiratory distress syndrome in these patients. A secondary objective was to identify the early (first 48 h from ICU admission) predictive factors for acute respiratory distress syndrome severity. An evolutive haematological disease (HR 1.71; 95% CI 1.13-2.58), moderate to severe acute respiratory distress syndrome (HR 1.81; 95% CI 1.13-2.69) and need for renal replacement therapy (HR 2.24; 95% CI 1.52-3.31) were associated with long-term mortality. Resolution of neutropaenia during ICU stay (HR 0.63; 95% CI 0.42-0.94) and early microbiological documentation (HR 0.62; 95% CI 0.42-0.91) were associated with survival. The extent of pulmonary infiltration observed on the first chest X-ray and the diagnosis of invasive fungal infection were the most relevant early predictive factors of the severity of acute respiratory distress syndrome. © 2016 The Association of Anaesthetists of Great Britain and Ireland.

    Pancreatic necrosis is an important determinant of patient outcome in severe acute pancreatitis (SAP). This prospective study was conducted to evaluate if perfusion CT (PCT) can predict the development of necrosis at an early stage in SAP. PCT was performed within 72 h of abdominal pain in 57 consecutive admitted patients of acute pancreatitis, out of which four patients were excluded. Thirty-two patients were classified as SAP and 21 as mild acute pancreatitis (MAP) on the basis of APACHE II or SIRS criteria or presence of organ failure. All patients underwent a follow-up CECT at 3 weeks to look for pancreatic necrosis. Out of 32 patients of SAP, 14 patients showed perfusion defects. The mean blood flow (BF) in these areas was 11.47 ± 5.56 mL/100 mL/min and median blood volume (BV) was 3.92 mL/100 mL (0.5-8.49 mL/100 mL). All these patients developed necrosis on follow-up scan. Two patients who did not show perfusion defects also developed necrosis. Remaining 37 patients (16 SAP and 21 MAP) did not show perfusion defect and did not develop necrosis on follow-up. All regions showing BF less than ≤23.45 mL/100 mL/min and BV ≤8.49 mL/100 mL developed pancreatic necrosis. The values of perfusion parameters may vary with the scanner, mathematical model and protocol used. The sensitivity and specificity of PCT for predicting pancreatic necrosis were 87.5% and 100%, respectively. The cut off values of BF and BV for predicting the development of pancreatic necrosis were 27.29 mL/100 mL/min and 8.96 mL/100 mL, respectively, based on ROC curve. PCT is a reliable tool for early prediction of pancreatic necrosis, which may open new avenues to prevent this ominous complication.

    We evaluated the severity assessment criteria for acute cholangitis (AC) of the Tokyo Guidelines 2013 (TG13) and developed a scoring system for predicting the need for urgent/early biliary drainage. We retrospectively reviewed 66 AC cases prospectively managed based on the TG07 and divided into an urgent/early biliary drainage group (n = 30) and elective biliary drainage group (n = 36). There were 26 mild, 27 moderate, and 13 severe cases based on the TG13. The TG13 assessment in 12 of the 17 cases requiring early biliary drainage based on the TG07 was moderate, but underestimated the other five cases as mild AC. When five predictors (blood urea nitrogen >20 mg/dL, SIRS presence, platelet count <120 000/μL, serum albumin level <3.0 g/dL, age ≥75 years old) were used to devise a scoring system, the receiver-operator characteristic curve of the scores showed good test performance for predicting the need for urgent/early biliary drainage. The area under the curve (AUC) was 0.95 and higher than the TG13 AUC (0.80). The TG13 is practical, but some AC cases requiring urgent/early biliary drainage were underestimated as mild AC. The scoring system allows identification of high-risk AC patients and will improve the TG13. © 2014 Japanese Society of Hepato-Biliary-Pancreatic Surgery.

    Abstract The formulation of accurate clinical case definitions is an integral part of an effective process of public health surveillance. Although such definitions should, ideally, be based on a standardized and fixed collection of defining criteria, they often require revision to reflect new knowledge of the condition involved and improvements in diagnostic testing. Optimal case definitions also need to have a balance of sensitivity and specificity that reflects their intended use. After the 2009–2010 H1N1 influenza pandemic, the World Health Organization (WHO) initiated a technical consultation on global influenza surveillance. This prompted improvements in the sensitivity and specificity of the case definition for influenza – i.e. a respiratory disease that lacks uniquely defining symptomology. The revision process not only modified the definition of influenza-like illness, to include a simplified list of the criteria shown to be most predictive of influenza infection, but also clarified the language used for the definition, to enhance interpretability. To capture severe cases of influenza that required hospitalization, a new case definition was also developed for severe acute respiratory infection in all age groups. The new definitions have been found to capture more cases without compromising specificity. Despite the challenge still posed in the clinical separation of influenza from other respiratory infections, the global use of the new WHO case definitions should help determine global trends in the characteristics and transmission of influenza viruses and the associated disease burden.

    Full Text Available Substance P (SP, a member of tachykinin family, is involved in the inflammation of the central nervous system and in the appearance of cerebral edema. Higher serum levels of SP have been found in 18 patients with cerebral ischemia compared with healthy controls. The aim of our multi-center study was to analyze the possible association between serum levels of SP and mortality in ischemic stroke patients. We included patients with malignant middle cerebral artery infarction (MMCAI and a Glasgow Coma Scale (GCS lower than 9. Non-surviving patients at 30 days (n = 31 had higher serum concentrations of SP levels at diagnosis of severe MMCAI than survivors (n = 30 (p < 0.001. We found in multiple regression an association between serum concentrations of SP higher than 362 pg/mL and mortality at 30 days (Odds Ratio = 5.33; 95% confidence interval = 1.541–18.470; p = 0.008 after controlling for age and GCS. Thus, the major novel finding of our study was the association between serum levels of SP and mortality in patients suffering from severe acute ischemic stroke.

    Full Text Available Abstract Background Severe acute respiratory syndrome (SARS emerged in later February 2003, as a new epidemic form of life-threatening infection caused by a novel coronavirus. However, the immune-pathogenesis of SARS is poorly understood. To understand the host response to this pathogen, we investigated the gene expression profiles of peripheral blood mononuclear cells (PBMCs derived from SARS patients, and compared with healthy controls. Results The number of differentially expressed genes was found to be 186 under stringent filtering criteria of microarray data analysis. Several genes were highly up-regulated in patients with SARS, such as, the genes coding for Lactoferrin, S100A9 and Lipocalin 2. The real-time PCR method verified the results of the gene array analysis and showed that those genes that were up-regulated as determined by microarray analysis were also found to be comparatively up-regulated by real-time PCR analysis. Conclusions This differential gene expression profiling of PBMCs from patients with SARS strongly suggests that the response of SARS affected patients seems to be mainly an innate inflammatory response, rather than a specific immune response against a viral infection, as we observed a complete lack of cytokine genes usually triggered during a viral infection. Our study shows for the first time how the immune system responds to the SARS infection, and opens new possibilities for designing new diagnostics and treatments for this new life-threatening disease.

    Acute severe ulcerative colitis (ASUC) is a potentially life-threatening condition that requires early recognition, hospitalization and adequate treatment. Currently, the use of infliximab in ulcerative colitis (UC) is recommended in the case of severe disease refractory to corticosteroids, once that superimposed bacterial or viral infections (such as cytomegalovirus or Clostridium difficile) have been excluded. However, conventional weight-based regimens of infliximab might be insufficient for patients with ASUC. Accelerated infliximab induction regimen may increase its serum concentration levels and efficacy by reducing early colectomy rates in these patients. We report a 34 year old female presenting with an ASUC. She was initially treated with hydrocortisone 300 mg/day and mesalazine enemas 4 g/day with an unfavorable clinical response. At the fifth day of therapy, an accelerated induction therapy with infliximab was started in doses of 10 mg/kg at weeks 0, 1 and 4. After the second dose, there was a favorable response with reduction of abdominal pain, stool frequency and hematochezia. She was discharged with prednisone and azathioprine. After a year of starting infliximab, the patient remains in clinical remission.

    We designed and validated a simple prehospital stroke scale to identify emergent large vessel occlusion (ELVO) in patients with acute ischemic stroke and compared the scale to other published scales for prediction of ELVO. A national historical test cohort of 3127 patients with information on intracranial vessel status (angiography) before reperfusion therapy was identified. National Institutes of Health Stroke Scale (NIHSS) items with the highest predictive value of occlusion of a large intracranial artery were identified, and the most optimal combination meeting predefined criteria to ensure usefulness in the prehospital phase was determined. The predictive performance of Prehospital Acute Stroke Severity (PASS) scale was compared with other published scales for ELVO. The PASS scale was composed of 3 NIHSS scores: level of consciousness (month/age), gaze palsy/deviation, and arm weakness. In derivation of PASS 2/3 of the test cohort was used and showed accuracy (area under the curve) of 0.76 for detecting large arterial occlusion. Optimal cut point ≥2 abnormal scores showed: sensitivity=0.66 (95% CI, 0.62-0.69), specificity=0.83 (0.81-0.85), and area under the curve=0.74 (0.72-0.76). Validation on 1/3 of the test cohort showed similar performance. Patients with a large artery occlusion on angiography with PASS ≥2 had a median NIHSS score of 17 (interquartile range=6) as opposed to PASS <2 with a median NIHSS score of 6 (interquartile range=5). The PASS scale showed equal performance although more simple when compared with other scales predicting ELVO. The PASS scale is simple and has promising accuracy for prediction of ELVO in the field. © 2016 American Heart Association, Inc.

    Full Text Available The aim of the present study was to determine whether lung volume recruitment (LVR acutely increases respiratory system compliance (Crs in individuals with severe respiratory muscle weakness (RMW. Individuals with RMW resulting from neuromuscular disease or quadriplegia (n=12 and healthy controls (n=12 underwent pulmonary function testing and the measurement of Crs at baseline, immediately after, 1 h after and 2 h after a single standardised session of LVR. The LVR session involved 10 consecutive supramaximal lung inflations with a manual resuscitation bag to the highest tolerable mouth pressure or a maximum of 50 cmH2O. Each LVR inflation was followed by brief breath-hold and a maximal expiration to residual volume. At baseline, individuals with RMW had lower Crs than controls (37±5 cmH2O versus 109±10 mL·cmH2O−1, p0.05. LVR had no significant effect on measures of pulmonary function at any time point in either group (all p>0.05. During inflations, mean arterial pressure decreased significantly relative to baseline by 10.4±2.8 mmHg and 17.3±3.0 mmHg in individuals with RMW and controls, respectively (both p<0.05. LVR acutely increases Crs in individuals with RMW. However, the high airway pressures during inflations cause reductions in mean arterial pressure that should be considered when applying this technique.

    The term severe acute respiratory infection (SARI) encompasses a heterogeneous group of respiratory illnesses. Grading the severity of SARI is currently reliant on indirect disease severity measures such as respiratory and heart rate, and the need for oxygen or intensive care. With the lungs being the primary organ system involved in SARI, chest radiographs (CXRs) are potentially useful for describing disease severity. Our objective was to develop and validate a SARI CXR severity scoring system. We completed validation within an active SARI surveillance project, with SARI defined using the World Health Organization case definition of an acute respiratory infection with a history of fever, or measured fever of ≥ 38 °C; and cough; and with onset within the last 10 days; and requiring hospital admission. We randomly selected 250 SARI cases. Admission CXR findings were categorized as: 1 = normal; 2 = patchy atelectasis and/or hyperinflation and/or bronchial wall thickening; 3 = focal consolidation; 4 = multifocal consolidation; and 5 = diffuse alveolar changes. Initially, four radiologists scored CXRs independently. Subsequently, a pediatrician, physician, two residents, two medical students, and a research nurse independently scored CXR reports. Inter-observer reliability was determined using a weighted Kappa (κ) for comparisons between radiologists; radiologists and clinicians; and clinicians. Agreement was defined as moderate (κ > 0.4–0.6), good (κ > 0.6–0.8) and very good (κ > 0.8–1.0). Agreement between the two pediatric radiologists was very good (κ = 0.83, 95 % CI 0.65–1.00) and between the two adult radiologists was good (κ = 0.75, 95 % CI 0.57–0. 93). Agreement of the clinicians with the radiologists was moderate-to-good (pediatrician:κ = 0.65; pediatric resident:κ = 0.69; physician:κ = 0.68; resident:κ = 0.67; research nurse:κ = 0.49, medical students: κ = 0.53 and κ = 0.56). Agreement between clinicians was good-to-very good

    Inflammation plays a crucial role in the pathogenesis and prognosis of stroke. We studied the behavior of lipoprotein(a) [Lp(a)], ferritin, and albumin as acute phase reactants and their roles in the severity and mortality of stroke. We recruited 100 consecutive patients with acute ischemic stroke and 120 controls. Blood samples were drawn on days 1 and 7 and at both 3 and 6 months. Stroke was classified using Trial of Org 10172 in Acute Stroke Treatment classification. Stroke severity was assessed using the National Institutes of Health Stroke Scale. Prognosis at 6 months was assessed using the modified Rankin Scale, and mortality was assessed using the Kaplan-Meier analysis. Serum levels of interleukin-6 (IL-6), Lp(a), ferritin, and albumin were measured using enzyme-linked immunosorbent assay, immunoturbidimetry, and chemiluminescence commercial kits, respectively. Levels of IL-6, Lp(a), and ferritin were consistently higher among cases than controls (P acute phase reactant while albumin acted as a negative acute phase reactant. There was no association between Trial of Org 10172 in Acute Stroke Treatment subtype and elevated serum levels of Lp(a), albumin, and ferritin. Lp(a) and ferritin were high in patients with severe stroke. Albumin was negatively correlated with stroke severity. Serum levels of Lp(a) ≥ 77 mg/dL, albumin ≤ 3.5 g/dL, and ferritin ≥ 370 ng/dL is associated with a significantly increased risk of having a poorer outcome in stroke. Serum levels of Lp(a) >77 mg/dL and albumin 77 mg/dL and albumin <3.5 g/dL had increased mortality. Copyright © 2013 National Stroke Association. Published by Elsevier Inc. All rights reserved.

    Calcimimetic NPS R-568 prevents parathyroid hyperplasia in rats with severe secondary hyperparathyroidism. Secondary hyperparathyroidism (secondary HPT) in chronic renal insufficiency (CRI) is characterized by multiglandular hyperplasia. In this study, we investigated the effects of the calcimimetic NPS R-568 on the parathyroid gland in rats with CRI induced by ligation of the renal arteries and severe secondary HPT induced by dietary phosphorus loading. Six days after surgery, high-phosphorus diet feeding was started, and NPS R-568 was administered to the rats for 56 days either by daily gavage (30 or 100 micromol/kg) or by continuous subcutaneous infusion (20 micromol/kg. day). After 54 days, serum PTH levels in vehicle-treated CRI rats were 1019 vs. 104 pg/mL in sham-operated controls. Infusion of NPS R-568 maintained serum PTH at levels comparable with those of sham-operated controls, whereas daily gavage also prevented much of the increase in CRI controls and decreased PTH levels intermittently in a dose-dependent fashion. Parathyroid gland enlargement was caused predominantly by hyperplasia. Total cell number per kg body wt was 3.5-fold higher in vehicle-treated CRI rats than in sham-operated controls. Both infusion and high-dose gavage of NPS R-568 completely prevented the increase in parathyroid cell number. These results demonstrate that the calcimimetic compound NPS R-568 can prevent both the increase in serum PTH levels and parathyroid hyperplasia in rats with CRI and severe secondary HPT. Moreover, these changes occurred despite decreases in serum 1, 25(OH)2D3 and increases in serum phosphate, suggesting a dominant role for the calcium receptor in regulating parathyroid cell proliferation.

    See Schiff (doi:10.1093/awx209) for a scientific commentary on this article. Patients with acute severe traumatic brain injury may recover consciousness before self-expression. Without behavioural evidence of consciousness at the bedside, clinicians may render an inaccurate prognosis, increasing the likelihood of withholding life-sustaining therapies or denying rehabilitative services. Task-based functional magnetic resonance imaging and electroencephalography techniques have revealed covert consciousness in the chronic setting, but these techniques have not been tested in the intensive care unit. We prospectively enrolled 16 patients admitted to the intensive care unit for acute severe traumatic brain injury to test two hypotheses: (i) in patients who lack behavioural evidence of language expression and comprehension, functional magnetic resonance imaging and electroencephalography detect command-following during a motor imagery task (i.e. cognitive motor dissociation) and association cortex responses during language and music stimuli (i.e. higher-order cortex motor dissociation); and (ii) early responses to these paradigms are associated with better 6-month outcomes on the Glasgow Outcome Scale-Extended. Patients underwent functional magnetic resonance imaging on post-injury Day 9.2 ± 5.0 and electroencephalography on Day 9.8 ± 4.6. At the time of imaging, behavioural evaluation with the Coma Recovery Scale-Revised indicated coma (n = 2), vegetative state (n = 3), minimally conscious state without language (n = 3), minimally conscious state with language (n = 4) or post-traumatic confusional state (n = 4). Cognitive motor dissociation was identified in four patients, including three whose behavioural diagnosis suggested a vegetative state. Higher-order cortex motor dissociation was identified in two additional patients. Complete absence of responses to language, music and motor imagery was only observed in coma patients. In patients with behavioural evidence

    Full Text Available Hydrogen (H2, a new antioxidant, was reported to reduce •OH and ONOO− selectively and inhibit certain proinflammatory mediators to product, without disturbing metabolic redox reactions or ROS involved in cell signaling. We herein aim to explore its protective effects on acute renal injury in sodium taurocholate-induced acute pancreatitis and its possible mechanisms. Rats were injected with hydrogen-rich saline (HRS group or normal saline (SO and SAP group through tail intravenously (6 mL/kg and compensated subcutaneously (20 mL/kg after successful modeling. Results showed that hydrogen-rich saline attenuated the following: (1 serum Cr and BUN, (2 pancreatic and renal pathological injuries, (3 renal MDA, (4 renal MPO, (5 serum IL-1β, IL-6, and renal TNF-α, HMGB1, and (6 tyrosine nitration, IκB degradation, and NF-κB activation in renal tissues. In addition, it increased the level of IL-10 and SOD activity in renal tissues. These results proved that hydrogen-rich saline attenuates acute renal injury in sodium taurocholate-induced acute pancreatitis, presumably because of its detoxification activity against excessive ROS, and inhibits the activation of NF-κB by affecting IκB nitration and degradation. Our findings highlight the potential value of hydrogen-rich saline as a new therapeutic method on acute renal injury in severe acute pancreatitis clinically.

    Full Text Available Objective: To study the effect of adjuvant therapy of ganglioside sodium on intracranial pressure (ICP, partial pressure of brain tissue oxygen (PbtO2, nerve injury molecules, nerve protection molecules and indexes of oxidative stress in patients with acute severe craniocerebral injury. Methods: Forty-seven patients with severe craniocerebral injury treated in the emergency department of our hospital during the period time from December 2012 to October 2015 were selected for retrospective analyses. They were divided into the ganglioside group and the normal treatment group according to the usage of ganglioside sodium in the process of the emergency treatment. At days 1, 3, 5 and 7 before and after treatment, the ICP and PbtO2 in patients of the two groups were measured. After 7 days of treatment, the nerve injury molecules, nerve protection molecules and the indexes of oxidative stress in serum of the patients of the two groups were determined. Results: At days 1, 3, 5 and 7 before and after treatment, the ICP in patients of the ganglioside group were all significantly lower than those of the normal treatment group, while the PbtO2 were all significantly higher than those of normal treatment group. After 7 days of treatment, the contents of serum methane dicarboxylic aldehyde, advanced oxidation protein products, 8-hydroxy-2'-deoxyguanosine urine, S100β, glial fibrillary acidic portein, neuron specific enolase, myelin basic protein, neuroglobin and ubiquitin carboxyl-terminal hydrolase L1 in patients of the ganglioside group were notably lower than those of the normal treatment group, while the contents of superoxidase dismutase, glutathione peroxidase, catalase, nerve growth factor and brain derived neurotrophic factor were significantly higher than those of the normal treatment group. Conclusions: The adjuvant therapy of ganglioside sodium in patients with severe craniocerebral injury can effectively reduce ICP, improve PbtO2 and alleviate

  9. Temporal profile of body temperature in acute ischemic stroke: relation to stroke severity and outcome

    Science.gov (United States)

    2012-01-01

    Background Pyrexia after stroke (temperature ≥37.5°C) is associated with poor prognosis, but information on timing of body temperature changes and relationship to stroke severity and subtypes varies. Methods We recruited patients with acute ischemic stroke, measured stroke severity, stroke subtype and recorded four-hourly tympanic (body) temperature readings from admission to 120 hours after stroke. We sought causes of pyrexia and measured functional outcome at 90 days. We systematically summarised all relevant previous studies. Results Amongst 44 patients (21 males, mean age 72 years SD 11) with median National Institute of Health Stroke Score (NIHSS) 7 (range 0–28), 14 had total anterior circulation strokes (TACS). On admission all patients, both TACS and non-TACS, were normothermic (median 36.3°C vs 36.5°C, p=0.382 respectively) at median 4 hours (interquartile range, IQR, 2–8) after stroke; admission temperature and NIHSS were not associated (r2=0.0, p=0.353). Peak temperature, occurring at 35.5 (IQR 19.0 to 53.8) hours after stroke, was higher in TACS (37.7°C) than non-TACS (37.1°C, ptemperatures. Sixteen (36%) patients became pyrexial, in seven (44%) of whom we found no cause other than the stroke. Conclusions Normothermia is usual within the first 4 hours of stroke. Peak temperature occurs at 1.5 to 2 days after stroke, and is related to stroke severity/subtype and more closely associated with poor outcome than admission temperature. Temperature-outcome associations after stroke are complex, but normothermia on admission should not preclude randomisation of patients into trials of therapeutic hypothermia. PMID:23075282

    Renal insufficiency (RI) has been reported to be associated with unfavorable clinical outcomes in patients undergoing percutaneous coronary interventions (PCI). However, little data is available regarding the impact of moderate to severe RI on clinical outcomes in patients with acute myocardial infarction (AMI) undergoing PCI. Between March 2003 and July 2007, 878 patients with AMI who underwent PCI were enrolled. Based on estimated glomerular filtration rate (eGFR) using the Modification of Diet in Renal Disease (MDRD) equation, patients were divided into two groups: eGFR <60 mL/min·m(2) (moderate to severe RI, group A) and eGFR ≥60 mL/min·m(2) (normal to mild RI, group B). The primary endpoint was all-cause mortality at 1-year after successful PCI. The secondary endpoints were non-fatal myocardial infarction (MI), target lesion revascularization (TLR), target vessel revascularization (TVR), stent thrombosis (ST) and major adverse cardiac events (MACE) at 1-year. In group A, patients were more often male and older, with diabetes and hypertension. Compared to patients in group B, group A showed significantly higher incidences of all-cause mortality, cardiac mortality, non-fatal MI and MACE. The needs of TLR and TVR, and the incidence of ST were not significantly different between the two groups. Independent predictors of 1-year mortality were eGFR <60 mL/min·m(2), male gender, older age and a lower left ventricular ejection fraction. In patients with AMI, moderate to severe RI was associated with mortality and MACE at 1-year after successful PCI. In addition, eGFR <60 mL/min·m(2) was a strong independent predictor of 1-year mortality.

    Full Text Available The emergence of severe acute respiratory syndrome (SARS in 2002 and 2003 affected global health and caused major economic disruption. Adequate animal models are required to study the underlying pathogenesis of SARS-associated coronavirus (SARS-CoV infection and to develop effective vaccines and therapeutics. We report the first findings of measurable clinical disease in nonhuman primates (NHPs infected with SARS-CoV.In order to characterize clinically relevant parameters of SARS-CoV infection in NHPs, we infected cynomolgus macaques with SARS-CoV in three groups: Group I was infected in the nares and bronchus, group II in the nares and conjunctiva, and group III intravenously. Nonhuman primates in groups I and II developed mild to moderate symptomatic illness. All NHPs demonstrated evidence of viral replication and developed neutralizing antibodies. Chest radiographs from several animals in groups I and II revealed unifocal or multifocal pneumonia that peaked between days 8 and 10 postinfection. Clinical laboratory tests were not significantly changed. Overall, inoculation by a mucosal route produced more prominent disease than did intravenous inoculation. Half of the group I animals were infected with a recombinant infectious clone SARS-CoV derived from the SARS-CoV Urbani strain. This infectious clone produced disease indistinguishable from wild-type Urbani strain.SARS-CoV infection of cynomolgus macaques did not reproduce the severe illness seen in the majority of adult human cases of SARS; however, our results suggest similarities to the milder syndrome of SARS-CoV infection characteristically seen in young children.

    The aim of presented study was to investigate the influence of Lactobacillus plantarum LS/07 and inulin on the activity of β-glucuronidase enzyme, and counts of coliform and lactobacilli in fresh caecal digesta, cytokine levels (IL-6, IL-8), and trancription nuclear factor kappa beta (NFκB) activities in colon tissue and blood samples of rats with dextran sulphate sodium (DSS) induced acute colitis. The rats were randomly divided into four groups - CG, AC, AC+PRE and AC+PRO. Colitis was induced using of 5% DSS in drinking water for 7d. DSS application increased activity of β-glucuronidase (P LS/07 decreased β-glucuronidase activity (P LS/07 and inulin suppressed expression observed markers, which play an important role in the inflammatory process, which predisposes their use in prevention or treatment of acute colitis.

    AIM: Escitalopram may prevent depression following acute coronary syndrome. We sought to estimate the effects of escitalopram on self-reported health and to identify subgroups with higher efficacy. METHODS: This is a secondary analysis of a 12-month double-blind clinical trial randomizing non......-depressed acute coronary syndrome patients to escitalopram (n = 120) or matching placebo (n = 120). The main outcomes were mean scores on Short Form 36 Health Survey (SF-36) domains, and diagnosis of depression was adjusted for baseline SF-36 scores. RESULTS: Escitalopram did not yield different SF-36...... trajectories on any scale compared with placebo (P > 0.28). Efficacy of escitalopram may have been better among those scoring at least the normative score on general health perceptions (hazard ratio (HR) for depression 0.17 (95% confidence interval 0.02-1.42) ) or social functioning (HR = 0.12 (0...

    To determine whether locally adapting a falls risk factor assessment tool results in an instrument with clinimetric properties sufficient to support an acute hospital's falls prevention program. Prospective cohort study of predictive validity and observational investigation of intra- and inter-rater reliability. Acute wards in two large hospitals in Melbourne, Australia. One hundred and thirty acute hospital inpatients participated in the predictive accuracy evaluation, with 25 and 35 inpatients used for the intra-rater and inter-rater reliability analyses, respectively. To develop a falls risk screen and assessment instrument through local adaptation of an existing tool. Clinimetric property analysis of new instrument (Western Health Falls Risk Assessment, WHeFRA) and comparison with 'gold standard tool' (STRATIFY). Fallers, falls and falls per 1000 bed days. Sensitivity (Sens), specificity (Spec), Youden Index (YI) and these three statistics based on event rate of falls (Sens(ER), Spec(ER) and YI(ER)), were calculated to determine predictive accuracy. Reliability was determined using intraclass correlation coefficient (ICC), weighted kappa and signed rank test. Seven participants (5.4%) fell, with 14 falls (fall rate: 10.7 falls per 1000 patient bed days). The WHeFRA instrument was significantly more accurate at predicting fallers and the rate of falls than the STRATIFY. Intra-rater reliability ICC (95% confidence intervals) for WHeFRA screen was 0.94 (0.86-0.97) and inter-rater reliability was 0.78 (0.61-0.88). Local adaptation of an existing tool resulted in an instrument with favorable clinimetric properties and may be a viable procedure for facilitating falls prevention program development and implementation in acute hospital settings.

    Acute Zika virus (ZIKV) infection is usually mild and self-limiting. Earlier, we reported three cases of fatal acute ZIKV infection in patients without typical signs of ZIKV, but rather with criteria of systemic inflammation response syndrome (SIRS). To follow up these observations, we prospectively included patients at the emergency room with temperature instability and suspected to have acute ZIKV infection, SIRS, or both. A total of 102 patients were included of whom N = 21 (21%) were suspected of acute ZIKV infection, N = 56 (55%) of acute ZIKV infection with SIRS criteria, and N = 25 (24%) of SIRS alone. ZIKV-PCR was positive in N = 21 (20%) patients. Eight (38%) ZIKV-positive patients needed admission to the hospital of whom four (50%) presented with SIRS alone. One ZIKV-positive patient had vascular co-morbidity and died following shock and severe coagulopathy. We confirm the hypothesis that acute ZIKV infection can present atypical and severely with systemic inflammation and have lethal course particularly amongst patients with significant prior disease.

    Acute renal failure is common in the neonatal intensive care unit but is often not recognized in its early phases, when it is potentially reversible. The typical patient with acute renal failure is premature, but many term infants are also at risk. One such group is those with severe bleeding, such as a subgaleal hemorrhage. In these cases, hypovolemia can quickly progress to ischemia, which affects many organs but has profound effects on the kidney. In term infants, acute renal failure is most commonly diagnosed in those with perinatal depression. This article presents a unique case of an infant with subgaleal and intracranial bleeding that resulted in acute renal failure requiring peritoneal dialysis in the hopes of the eventual restoration of kidney function.

    Infants with the severe variant of glucose-6-phosphate dehydrogenase (G6PD) deficiency may develop hyperbilirubinaemia sufficiently severe to cause kernicterus and death, acute haemolysis on exposure to oxidant stress, congenital non-spherocytic haemolytic anaemia and, rarely, increased susceptibility to bacterial infection. In spite of these potential problems, G6PD deficiency is often not included among screening programmes for inherited disorders. In a comprehensive screening and educational programme, we tested around 34,000 infants for G6PD deficiency. Of the total group, 18.4% (24.5% boys and 11.8% girls) were deficient. Forty-two of the 6246 (0.67%) G6PD-deficient infants required exchange transfusion. None of them developed kernicterus. By contrast, of 4755 infants who had not been screened because they were born at home, three developed kernicterus. In addition, four G6PD-deficient infants had developed kernicterus in the 20-month period prior to the screening programme. None of the hyperbilirubinaemic infants had blood group incompatibility or any other identifiable cause of hyperbilirubinaemia. To avoid this disastrous result, we believe that neonatal screening for G6PD deficiency, together with a comprehensive education programme, is advisable in those parts of the world where the severe variant of G6PD deficiency is prevalent.

    To evaluate the prevalence and clinical features of Celiac disease among children with severe acute malnutrition (SAM). This prospective observational study was conducted in PBM Children Hospital, Bikaner from July 2012 through December 2013. All consecutively admitted children with SAM were recruited. All subjects were screened for Celiac disease by serological test for IgA-anti tissue Transglutaminase (IgA tTG) antibodies. All seropositive children underwent upper gastrointestinal endoscopy for small bowel biopsy for the confirmation. Clinical features of patients with and without celiac disease were compared. The sero-prevalence (IgA tTg positivity) of Celiac disease was found to be 15.38% while prevalence of biopsy confirmed Celiac disease was 14.42% among SAM children. Abdominal distension, diarrhea, anorexia, constipation, pain in abdomen, vitamin deficiencies, edema, clubbing and mouth ulcers were more common in patients of Celiac disease compared to patients without Celiac disease but the difference was statistically significant only for abdominal distension and pain abdomen. There is a high prevalence of Celiac disease in SAM. Screening for Celiac disease (especially in presence of pain abdomen and abdominal distension) should be an essential part of work-up in all children with SAM.

    Full Text Available Abstract Background Diarrhea is common in patients with Crohn's disease and may be accompanied by acid base disorders, most commonly metabolic acidosis due to intestinal loss of bicarbonate. Case Presentation Here, we present a case of severe metabolic alkalosis in a young patient suffering from M. Crohn. The patient had undergone multiple resections of the intestine and suffered from chronic kidney disease. He was now referred to our clinic for recurrent acute kidney injury, the nature of which was pre-renal due to profound volume depletion. Renal failure was associated with marked hypochloremic metabolic alkalosis which only responded to high volume repletion and high dose blockade of gastric hypersecretion. Intestinal failure with stomal fluid losses of up to 5.7 litres per day required port implantation to commence parenteral nutrition. Fluid and electrolyte replacement rapidly improved renal function and acid base homeostasis. Conclusions This case highlights the important role of gastrointestinal function to maintain acid base status in patients with Crohn's disease.

  1. Mechanical Ventilation during Extracorporeal Membrane Oxygenation in Patients with Acute Severe Respiratory Failure

    2017-01-01

    Full Text Available Conventionally, a substantial number of patients with acute respiratory failure require mechanical ventilation (MV to avert catastrophe of hypoxemia and hypercapnia. However, mechanical ventilation per se can cause lung injury, accelerating the disease progression. Extracorporeal membrane oxygenation (ECMO provides an alternative to rescue patients with severe respiratory failure that conventional mechanical ventilation fails to maintain adequate gas exchange. The physiology behind ECMO and its interaction with MV were reviewed. Next, we discussed the timing of ECMO initiation based on the risks and benefits of ECMO. During the running of ECMO, the protective ventilation strategy can be employed without worrying about catastrophic hypoxemia and carbon dioxide retention. There is a large body of evidence showing that protective ventilation with low tidal volume, high positive end-expiratory pressure, and prone positioning can provide benefits on mortality outcome. More recently, there is an increasing popularity on the use of awake and spontaneous breathing for patients undergoing ECMO, which is thought to be beneficial in terms of rehabilitation.

    Full Text Available Background. SARS (severe acute respiratory syndrome is a recently recognized new infectious respiratory illness, which first appeared in southern China in November 2002, and has since then within months spread to 29 countries. In total, 8437 cases and 813 deaths occurred (situation as of August 1, 2003. SARS is caused by a novel coronavirus that is primarily spread by large droplet transmission, less commonly by surface contamination or by air (airborne. Around half of the infected were health care workers; the majority of cases acquired the infection in the hospital.Conclusions. Incubation period of SARS is 2 to 10 days. Early manifestations include fever, myalgia, and headache, followed 2 to 4 days later by cough, shortness of breath, and diarrhea. In 10–20% of patients, tracheal intubation and mechanical ventilation is required. Case-fatality is approximately 15%, in patients aged 60 years or older may be higher than 40%. There is no specific therapy or vaccine, and management consists of supportive care. This article summarizes updated information regarding epidemiology, clinical features, etiologic agent, modes of transmission of the disease, and infection control measures to contain SARS.

    To test the use of diffusion-weighted magnetic resonance imaging (DW-MRI) to differentiate between different degrees of severity of acute pancreatitis (AP). Thirty-six patients who underwent DW-MRI and magnetic resonance cholangiopancreatography were divided into patients with mild AP (mAP, n = 15), patients with necrotizing AP (nAP, n = 8), and patients with a normal pancreas (nP, n = 15; controls). The pancreas was divided into head, body, and tail, and each segment was classified according to image features: pattern 1, normal; pattern 2, mild inflammation; and pattern 3, necrosis. Apparent diffusion coefficients (ADCs) were measured in each segment and correlated with clinical diagnoses. A total of 108 segments was assessed (three segments per patient). Segments classified as pattern 1 in the nP and mAP groups showed similar ADC values (P = 0.29). ADC values calculated for the pancreatic segments grouped according to the different image patterns (1-3) were significantly different (P < 0.001). Comparisons revealed significant differences in signal intensity between all three patterns (P < 0.05). DW-MRI was a compatible and safe image option to differentiate tissue image patterns in patients with mAP, nAP, and nP, mainly in those with contraindications to contrast-enhanced MRI (which is classically required for determining the presence of necrosis) or computed tomography. ADC measures allowed precise differentiation between patterns 1, 2, and 3.

    Dapsone is a drug commonly used in the treatment of leprosy. In Europe it is rarely prescribed, mostly for the treatment of skin diseases such as dermatitis herpetiformis. Poisoning with dapsone is rare and reports of such cases are of interest for toxicological practice. We describe the only acute dapsone poisoning in a caseload series of 21,000 intoxications treated in the Clinical Toxicology Clinic at St George University Hospital in Plovdiv, Bulgaria between 1999 and 2013. We report on a 36-year-old woman who attempted deliberate self-poisoning with an ingestion of approximately 4.5 g of dapsone and 0.3 g of olanzapine. On admission, the patient was in a state of severe intoxication and comatose. On admission to hospital 9 hours after the ingestion, the methemoglobin level was 51.7%. The patient recovered 8 days later. She received complex treatment including intubation, ventilation, repeated gastric lavage, hemodialysis, blood exchange transfusion and antidote treatment with methylene blue. She was discharged in good clinical condition with minimal organ damage such as mild toxic hepatitis.

  5. Acute tubulointerstitial nephritis with severe renal impairment associated with multisystem IgG4-related disease

    Rafael Coimbra Ferreira Beltrame

    Full Text Available Abstract The IgG4-related disease has a wide clinical spectrum where multiple organs can be affected, and the diagnosis depends on typical histopathological findings and an elevated IgG4 expression in plasma cells in the affected tissue. We describe the clinical presentation and evolution of a patient with acute tubulointerstitial nephritis, severe kidney failure and systemic manifestations such as lymphadenomegaly and chronic pancreatitis. The diagnosis was confirmed by the clinical picture and kidney and lymph node histopathology, in which immunohistochemistry of the lymphoid tissue showed policlonality and increased expression of IgG4, with a IgG4/total IgG ratio > 80%. The patient was treated with prednisone at a dose of 60 mg/day, followed by mycophenolate mofetil, and showed clinical and renal function improvement at 6 months of follow-up. The high index of suspicion of IgG4-related disease with multisystem involvement and the early treatment of this condition are essential to improve the prognosis of affected patients.

    Conventionally, a substantial number of patients with acute respiratory failure require mechanical ventilation (MV) to avert catastrophe of hypoxemia and hypercapnia. However, mechanical ventilation per se can cause lung injury, accelerating the disease progression. Extracorporeal membrane oxygenation (ECMO) provides an alternative to rescue patients with severe respiratory failure that conventional mechanical ventilation fails to maintain adequate gas exchange. The physiology behind ECMO and its interaction with MV were reviewed. Next, we discussed the timing of ECMO initiation based on the risks and benefits of ECMO. During the running of ECMO, the protective ventilation strategy can be employed without worrying about catastrophic hypoxemia and carbon dioxide retention. There is a large body of evidence showing that protective ventilation with low tidal volume, high positive end-expiratory pressure, and prone positioning can provide benefits on mortality outcome. More recently, there is an increasing popularity on the use of awake and spontaneous breathing for patients undergoing ECMO, which is thought to be beneficial in terms of rehabilitation.

    Acute kidney injury (AKI) is a severe complication in critically ill children. The aim of the study was to describe the characteristics of AKI, as well as to analyse the prognostic factors for mortality and renal replacement therapy (RRT) in children admitted to Paediatric Intensive Care Units (PICUs) in Spain. Prospective observational multicentre study including children from 7 days to 16 years old who were admitted to a PICU. A univariate and multivariate logistic regression analysis of the risk factors for mortality and renal replacement therapy at PICU discharge were performed. A total of 139 cases of AKI were analysed. RRT was necessary in 60.1% of cases. Mortality rate was 32.6%. At PICU discharge RRT was necessary in 15% of survivors. Thrombopenia and low creatinine clearance values were prognostic markers of RRT at PICU discharge. High values of platelets, serum creatinine and weight were associated with higher survival. Critically ill children with AKI had a high mortality and morbidity rate. Platelet values and creatinine clearance are markers of RRT at PICU discharge, whereas number of platelets, serum creatinine and weight were associated with mortality.

    Full Text Available Tet is a type of alkaloid extracted from Stephania tetrandra, and it has recently been demonstrated that Tet can protect against inflammation and free radical injury and inhibit the release of inflammatory mediators. The present study was designed to observe the protective effect of Tet on sodium taurocholate-induced severe acute pancreatitis (SAP. The rat model of SAP was induced by retrograde bile duct injection of sodium taurocholate and then treated with Verapamil and Tet. The results showed that Tet can reduce NF-κB activation in pancreas issue, inhibit the SAP cascade, and improve SAP through inducing pancreas acinar cell apoptosis and stabilizing intracellular calcium in the pancreas, thus mitigating the damage to the pancreas. Our study revealed that Tet may reduce systemic inflammatory response syndrome (SIRS and multiple organ dysfunction syndromes (MODS to protect against damage, and these roles may be mediated through the NF-κB pathway to improve the proinflammatory/anti-inflammatory imbalance.

    A 66-year-old man was admitted for severe acute alcoholic pancreatitis with infected pancreatic necrosis (IPN). Abdominal computed tomography revealed an inflamed pancreatic head, a dilated main pancreatic duct (MPD), and a large cavity with heterogeneous fluid containing gas adjacent to the pancreatic head, and extending to the pelvis. The cavity was drained percutaneously near the pancreatic head on admission; another tube was inserted into the pelvic cavity on hospital day 3. The drained fluid contained pus with high amylase concentration. Nasopancreatic drainage tube placement was unsuccessfully attempted on hospital day 9. On hospital day 23, percutaneous puncture of the MPD and placement of a pancreatic duct drainage tube was performed. Pancreatography revealed major extravasation from the pancreatic head. The IPN cavity receded; the percutaneous IPN drainage tube was removed on hospital day 58. On hospital day 83, the pancreatic drainage was changed to a transpapillary pancreatic stent, and the patient was discharged. Measuring the amylase concentration of peripancreatic fluid collections can aid in the diagnosis of pancreatic duct disruption; moreover, dual percutaneous necrotic cavity drainage plus pancreatic duct drainage may be essential for treating IPN. If transpapillary drainage tube placement is difficult, percutaneous pancreatic duct drainage may be feasible.

    The EPR TM has incorporated several design features in order to specifically address major severe accident safety issues. In particular, it was designed with the objective to transfer high pressure core melt scenarios into a low pressure scenario with high reliability so that a high pressure vessel failure can be practically eliminated. It is the key issue in the defense-in-depth approach, for a postulated severe accident with core melting, to prevent any risk of containment failure due to possible Direct Containment Heating or due to reactor vessel rocketing which results from vessel failure at high pressure. Temperature-induced steam generator tube rupture, which could lead to a radiological containment bypass, has also to be prevented. On the basis of the analysis of the main high pressure core melt scenarios which are calculated with the MAAP4.07 code which was developed to support the EPR TM, this paper explores the benefits of primary depressurization by dedicated valves on transient evolutions. It specifically addresses the thermal response of the structures by sensitivity studies involving the timing of valve actuation. It outlines that a grace period of at least one hour is available for a delayed valve actuation without inducing excessive loads and without increasing the risk of a temperature-induced steam generator tube rupture.

    Full Text Available High-mobility group box 1 protein (HMGB1, a ubiquitous nuclear protein, drives proinflammatory responses when released extracellularly. It plays a key role as a distal mediator in the development of acute lung injury (ALI. Sodium butyrate, an inhibitor of histone deacetylase, has been demonstrated to inhibit HMGB1 expression. This study investigates the effect of sodium butyrate on burn-induced lung injury. Sprague-Dawley rats were divided into three groups: 1 sham group, sham burn treatment; 2 burn group, third-degree burns over 30% total body surface area (TBSA with lactated Ringer's solution for resuscitation; 3 burn plus sodium butyrate group, third-degree burns over 30% TBSA with lactated Ringer's solution containing sodium butyrate for resuscitation. The burned animals were sacrificed at 12, 24, and 48 h after burn injury. Lung injury was assessed in terms of histologic changes and wet weight to dry weight (W/D ratio. Tumor necrosis factor (TNF-α and interleukin (IL-8 protein concentrations in bronchoalveolar lavage fluid (BALF and serum were measured by enzyme-linked immunosorbent assay, and HMGB1 expression in the lung was determined by Western blot analysis. Pulmonary myeloperoxidase (MPO activity and malondialdehyde (MDA concentration were measured to reflect neutrophil infiltration and oxidative stress in the lung, respectively. As a result, sodium butyrate significantly inhibited the HMGB1 expressions in the lungs, reduced the lung W/D ratio, and improved the pulmonary histologic changes induced by burn trauma. Furthermore, sodium butyrate administration decreased the TNF-α and IL-8 concentrations in BALF and serum, suppressed MPO activity, and reduced the MDA content in the lungs after severe burn. These results suggest that sodium butyrate attenuates inflammatory responses, neutrophil infiltration, and oxidative stress in the lungs, and protects against remote ALI induced by severe burn, which is associated with inhibiting HMGB1

    Molecular hydrogen, which reacts with the hydroxyl radical, has been considered as a novel antioxidant. Here, we evaluated the protective effects of hydrogen-rich saline on the L-arginine (L-Arg)-induced acute pancreatitis (AP). AP was induced in Sprague-Dawley rats by giving two intraperitoneal injections of L-Arg, each at concentrations of 250 mg/100 g body weight, with an interval of 1 h. Hydrogen-rich saline (>0.6 mM, 6 ml/kg) or saline (6 ml/kg) was administered, respectively, via tail vein 15 min after each L-Arg administration. Severity of AP was assessed by analysis of serum amylase activity, pancreatic water content and histology. Samples of pancreas were taken for measuring malondialdehyde and myeloperoxidase. Apoptosis in pancreatic acinar cell was determined with terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick-end labeling technique (TUNEL). Expression of proliferating cell nuclear antigen (PCNA) and nuclear factor kappa B (NF-{kappa}B) were detected with immunohistochemistry. Hydrogen-rich saline treatment significantly attenuated the severity of L-Arg-induced AP by ameliorating the increased serum amylase activity, inhibiting neutrophil infiltration, lipid oxidation and pancreatic tissue edema. Moreover, hydrogen-rich saline treatment could promote acinar cell proliferation, inhibit apoptosis and NF-{kappa}B activation. These results indicate that hydrogen treatment has a protective effect against AP, and the effect is possibly due to its ability to inhibit oxidative stress, apoptosis, NF-{kappa}B activation and to promote acinar cell proliferation.

    Full Text Available BACKGROUND Recent advances in pathophysiology and therapeutic measures suggest that patients suffering from acute pancreatitis (AP should undergo an early evaluation and treatment in Internal Medicine wards. Severe AP, usually associated with pancreatic necrosis and peripancreatic fluid collections, may be frequently complicated by distant organ(s involvement. RESULTS The dreadful multi-organ failure may occur as an early event (during the first week of the disease or in association with the infection of pancreatic necrosis in a later stage. So, during the clinical outcome, physicians may be compelled to counteract cardio-circulatory, pulmonary, renal, hepatic, haematological and hydro-electrolytic complex derangements. Arterial hypotension and shock may be consequence of hypovolemia and/or hearth failure or septic shock syndrome. Pleural effusions are frequent in the early phase of the disease as well as pulmonary densifications and renal insufficiency. Urinary, pulmonary, and biliary infections may intervene during all phases of the disease whereas pancreatic necrosis and fluid collections infections are more frequent after the second week of hospitalization. Prognostic evaluation should be obtained by simple and precise scoring system such as the modified Marshall score and CT-scan severity index. CONCLUSIONS Treatment must be initiated as soon as possible with special focusing on fluid and nutritional supplementation, pain control, cardio-respiratory support, antiproteases and antibiotics. Invasive procedures such as endoscopic sphincterotomy in biliary AP with cholangitis and/or obstruction and percutaneous drainage should be utilized in specific cases. Surgical necrosectomy is mandatory in patients with documented infection of pancreatic necrosis.

    Despite extensive research, the mortality rate of patients with sepsis-induced acute kidney injury (AKI) is unacceptably high, especially in the elderly. Current sepsis models have difficulties in reproducing AKI. This study aimed to develop a novel, clinically relevant mouse model for sepsis-induced AKI by uterine ligation and inoculation of bacteria. In addition, the age dependency of the severity of sepsis and sepsis-induced AKI was studied by validating this model in three different age categories. Experimental animal investigation. University research laboratory. Young (12-14 wks), aged (46-48 wks), and old (70-72 wks) C57BL/6 female mice were used as models for adolescent, adult premenopausal, and elderly postmenopausal women, respectively. Uterine ligation and inoculation with 10 colony forming unit Escherichia coli or saline (sham) was performed; in vivo imaging with a luminescent Escherichia coli strain documented the course of infection. All mice had established Escherichia coli sepsis at 48 hrs postinfection, with higher mortality rate in old (43%) compared to aged (23%) or young (9%) mice. Infected mice had elevated serum or plasma cytokine, chemokine (tumor necrosis factor, interleukin-6, keratinocyte-derived chemokine, monocyte chemoattractant protein 1, and interleukin-10), and NOx concentrations compared to sham mice. AKI was confirmed by renal histology. Serum creatinine concentrations at 48 hrs increased with age (mean ± SEM; controls 0.18 ± 0.03 mg/dL, young 0.28 ± 0.03 mg/dL, aged 0.38 ± 0.05 mg/dL, and old 0.44 ± 0.06 mg/dL). The uterine ligation and inoculation model for sepsis-induced AKI starts from a real infectious focus and shows an age-dependent severity of septic AKI that resembles AKI in humans.

  16. The effectiveness of interventions in the prevention and management of aggressive behaviours in patients admitted to an acute hospital setting: a systematic review.

    studies and one dissertation met the inclusion criteria and were included in the review. The evidence identified includes: the benefit of education and training of acute care nurses in aggression management techniques; the use of "as required" medications to minimise harm to patients and staff; and that specific interventions such as music therapy and physical restraint may play a role in managing aggressive and/or violent behaviours from patients in the acute care setting. This review makes several recommendations for clinical practice to prevent and manage aggressive behaviours in acute hospital patients. However due to the lack of high quality intervention studies conducted in the acute care setting there is huge scope for future research in this area.

    The outcome of severe acute subdural hematoma is unfavorable. In particular, patients with levels of consciousness of Glasgow Coma Scale(GCS)3 or 4 tend to be refractory to treatment. Decompressive craniotomy should be promptly performed to remove hematoma. However, if an operating room is not immediately available, emergency burr hole surgery is sometimes performed in the emergency room(primary care room)prior to craniotomy. A previous study has reported that the interval from injury to surgery influences the outcome of severe acute subdural hematoma. Therefore, emergency decompression is important to effectively treat patients with severe acute subdural hematoma. We present the cases of two patients with acute subdural hematomas. In both cases, emergency decompressive craniotomy(hematoma removal after craniotomy and external decompression)was performed in the emergency room of the Emergency and Critical Care Center. In both cases, the surgery was followed by favorable outcomes. Case 1 was a 36-year-old female. The patient's level of consciousness upon arrival was GCS 3. The interval from injury to diagnosis on the basis of CT findings was 75 minutes. Surgery began 20 minutes after diagnosis. Case 2 was a 25-year-old male. The second patient's level of consciousness upon arrival was GCS 4. The interval from injury to diagnosis on the basis of CT findings was 60 minutes. Surgery was begun 40 minutes after diagnosis. In both patients, we observed anisocoria and the loss of the light reflex. However, the postoperative course was favorable, and both patients were discharged. In summary, to treat severe acute subdural hematomas, early emergency decompressive craniotomy is optimal. Emergency decompressive surgery in the emergency room is independent of operating room or staff. Therefore, emergency decompressive craniotomy may improve the outcome of patients with severe acute subdural hematomas.

    Full Text Available It has proved that muscle paralysis was more protective for injured lung in severe acute respiratory distress syndrome (ARDS, but the precise mechanism is not clear. The purpose of this study was to test the hypothesis that abdominal muscle activity during mechanically ventilation increases lung injury in severe ARDS.Eighteen male Beagles were studied under mechanical ventilation with anesthesia. Severe ARDS was induced by repetitive oleic acid infusion. After lung injury, Beagles were randomly assigned into spontaneous breathing group (BIPAPSB and abdominal muscle paralysis group (BIPAPAP. All groups were ventilated with BIPAP model for 8h, and the high pressure titrated to reached a tidal volume of 6ml/kg, the low pressure was set at 10 cmH2O, with I:E ratio 1:1, and respiratory rate adjusted to a PaCO2 of 35-60 mmHg. Six Beagles without ventilator support comprised the control group. Respiratory variables, end-expiratory volume (EELV and gas exchange were assessed during mechanical ventilation. The levels of Interleukin (IL-6, IL-8 in lung tissue and plasma were measured by qRT-PCR and ELISA respectively. Lung injury scores were determined at end of the experiment.For the comparable ventilator setting, as compared with BIPAPSB group, the BIPAPAP group presented higher EELV (427±47 vs. 366±38 ml and oxygenation index (293±36 vs. 226±31 mmHg, lower levels of IL-6(216.6±48.0 vs. 297.5±71.2 pg/ml and IL-8(246.8±78.2 vs. 357.5±69.3 pg/ml in plasma, and lower express levels of IL-6 mRNA (15.0±3.8 vs. 21.2±3.7 and IL-8 mRNA (18.9±6.8 vs. 29.5±7.9 in lung tissues. In addition, less lung histopathology injury were revealed in the BIPAPAP group (22.5±2.0 vs. 25.2±2.1.Abdominal muscle activity during mechanically ventilation is one of the injurious factors in severe ARDS, so abdominal muscle paralysis might be an effective strategy to minimize ventilator-induce lung injury.

    2008-01-01

    Full Text Available Situs inversus totalis is an inherited condition characterized by a mirror-image transposition of thoracic and abdominal organs. It often coexists with other anatomical variations. Transposition of the organs imposes special demands on the diagnostic and surgical skills of the surgeon. We report a case of a 34-year-old female patient presented with left upper quadrant pain, signs of acute abdomen, and unknown situs inversus totalis. Severe acute cholecystitis was diagnosed, and an uneventful laparoscopic cholecystectomy was performed. A posterior cystic artery was identified and ligated. Laparoscopic cholecystectomy is feasible in patients with severe acute calculus cholecystitis and situs inversus totalis; however, the surgeon should be alert of possible anatomic variations.

    Acute kidney injury in patients with acute pancreatitis carries a poor prognosis. Hemolytic uremic syndrome (HUS) is characterized by non-immune hemolytic anemia, thrombocytopenia, and renal failure caused by platelet thrombi in the microcirculation of the kidney, and though rare in adults it is associated with high mortality and a high rate of chronic renal failure. Herein, we report a case of alcohol-induced acute pancreatitis in a 38-year-old Chinese female complicated by HUS. Her renal function progressively deteriorated in 2 days, and daily continuous renal replacement therapy (CRRT) was thus performed for a total of 13 treatments. She also received intermittent transfusions of fresh frozen plasma. Her renal failure was successfully managed, with subsequent return of normal renal function. She was discharged 1 month after admission and follow-up at 3 months revealed normal urea and creatinine. CRRT was shown to be useful for the treatment of HUS following acute pancreatitis. Prior case reports and our case should remind clinicians that HUS is a possible complication of acute pancreatitis. This study highlights the importance of early diagnosis and prompt initiation of CRRT to prevent mortality and improve outcomes.

    To study the safety of epidural anesthesia (EA), its effect on pancreatic perfusion and the outcome of patients with acute pancreatitis (AP). From 2005 to August 2010, patients with predicted severe AP [Ranson score ≥ 2, C-reactive protein > 100 or necrosis on computed tomography (CT)] were prospectively randomized to either a group receiving EA or a control group treated by patient controlled intravenous analgesia. Pain management was evaluated in the two groups every eight hours using the visual analog pain scale (VAS). Parameters for clinical severity such as length of hospital stay, use of antibiotics, admission to the intensive care unit, radiological/clinical complications and the need for surgical necrosectomy including biochemical data were recorded. A CT scan using a perfusion protocol was performed on admission and at 72 h to evaluate pancreatic blood flow. A significant variation in blood flow was defined as a 20% difference in pancreatic perfusion between admission and 72 h and was measured in the head, body and tail of the pancreas. We enrolled 35 patients. Thirteen were randomized to the EA group and 22 to the control group. There were no differences in demographic characteristics between the two groups. The Balthazar radiological severity score on admission was higher in the EA group than in the control group (mean score 4.15 ± 2.54 vs 3.38 ± 1.75, respectively, P = 0.347) and the median Ranson scores were 3.4 and 2.7 respectively (P = NS). The median duration of EA was 5.7 d, and no complications of the epidural procedure were reported. An improvement in perfusion of the pancreas was observed in 13/30 (43%) of measurements in the EA group vs 2/27 (7%) in the control group (P = 0.0025). Necrosectomy was performed in 1/13 patients in the EA group vs 4/22 patients in the control group (P = 0.63). The VAS improved during the first ten days in the EA group compared to the control group (0.2 vs 2.33, P = 0.034 at 10 d). Length of stay and mortality

    Predicting acute renal failure in patients with severe sepsis is important, because patients may need renal replacement therapy (RRT). Neutrophil gelatinase-associated lipocalin (NGAL) has been evaluated for its ability to detect and predict acute kidney injury (AKI) in critically ill patients. This study aimed to assess the predictive value of plasma NGAL for acute renal failure in adult severely septic patients. Thirty healthy adults and 85 adult patients admitted to the medical intensive care unit (ICU) were enrolled. Serum creatinine, plasma NGAL, and interleukin (IL)-6, IL-10, and IL-17 levels were evaluated. AKI was classified as Risk, Injury, Failure, Loss of kidney function, and End-stage kidney disease (RIFLE). RIFLE-Failure (RIFLE-F) developed in 30 of 76 (39.5%) patients with severe sepsis without chronic kidney disease within 7 days after ICU admission. Serum creatinine, plasma NGAL, IL-6, and IL-10 could predict RIFLE-F within 7 days after ICU admission. The discriminatory power of plasma NGAL was not significant for predicting hospital mortality. The area under the receiver operating characteristic curve of plasma NGAL was not higher than that of serum creatinine in predicting RIFLE-F within 7 days. Plasma NGAL is a useful tool for predicting acute renal failure in adult patients with severe sepsis. Serum creatinine has a similar ability to detect RIFLE-F occurrence. Copyright © 2016.

    Plant features and operator actions which have been found to be important in either preventing or mitigating severe accidents in PWRs with large dry containments have been identified. These features and actions were developed from insights derived from reviews of risk assessments performed specifically for the Zion plant and from assessments of other relevant studies. Accident sequences that dominate the core-damage frequency and those accident sequences that are of potentially high consequence were identified. Vulnerabilities of the large dry containment to severe accident containment loads were also identified. In addition, those features of a PWR with a large dry containment, which are important for preventing core damage and are available for mitigating fission-product release to the environment were identified. The report is issued to provide focus to the analyst examining an individual plant. The report calls attention to plant features and operator actions and provides a list of deterministic tributes for assessing those features and actions found to be helpful in reducing the overall risk for Zion and other PWRs with large dry containments. Thus, the guidance is offered as a resource in examining the subject plant to determine if the same, or similar, plant features and operator actions will be of value in reducing overall plant risk.

    Plant features and operator actions, which have been found to be important in either preventing or mitigating severe accidents in BWRs with Mark II containments (BWR Mark II's) have been identified. These features and actions were developed from insights derived from reviews of in-depth risk assessments performed specifically for the Limerick and Shoreham plants and from other relevant studies. Accident sequences that dominate the core-damage frequency and those accident sequences that are of potentially high consequence were identified. Vulnerabilities of the BWR Mark II to severe-accident containment loads were also noted. In addition, those features of a BWR Mark II, which are important for preventing core damage and are available for mitigating fission-product release to the environment were also identified.

    Full Text Available Objectives. Rates of negative laparotomy (NL for acute appendicitis have been reported as 15% and parasitosis contributed to 2%. This study was planned to reduce the rates of NL by preoperative determination of parasitosis. Methods. In retrospective examination of 2730 appendectomy specimens in Hitit University Department of General Surgery between 2008 and 2012, 55 patients were determined with parasitosis and compared with 102 age-matched randomly selected patients with lymphoid hyperplasia. Results. The parasite group comprised 63.6% females with a mean age of 15.1 years. The number of patients in the parasitosis group increased from city centre to rural areas of towns and villages (p2.2% was determined as a diagnostic value. Conclusion. It is important to determine parasitosis to prevent NL. When acute appendicitis is considered for young patients living in rural areas, the observation of high eosinophil together with negative sonographic findings should bring Enterobius vermicularis parasitosis to mind and thereby should prevent NL.

    A 29-year-old pregnant woman was referred to our hospital with suspected acute pancreatitis. On admission, the serum levels of pancreatic enzyme, total cholesterol and triglyceride were markedly elevated, which suggesting acute pancreatitis with hyperlipidemia. Treatment consisted of continuous hemodiafiltration, LDL apheresis, heparin and insulin combination therapy. On the 24th day of hospitalization, a cesarean section delivery resulted in the birth of a healthy infant. We reported a case of hyperlipidemia-induced acute pancreatitis in a woman with second trimester pregnancy, where multidisciplinary treatment was quite effective.

    Full Text Available The preventative and curative effects of some plant derived agents based on plant extracts or essential oils were studied at different concentrations against Erysiphe cichoracearum DC. ex Merat, the causal pathogen of okra powdery mildew by the detached leaf-disk and potted plants bioassays. Through detached leaf-disk assay, the highest mean preventative effect (97.74% was recorded by neem seed oil followed by jojoba oil (89.82% and extract of Rynoutria sachalinensis (82.77%. Neem seed oil at 1% was the most effective agent followed by jojoba oil and extract of R. sachalinensis at 1.5% and 2%, respectively, where they suppressed E. cichoracearum completely. Potted plants assay revealed that neem seed oil, jojoba oil and extract of R. sachalinensis as well as the fungicide (active ingredient dinocap showed higher preventative efficacy at all leaf olds treated after 7 and 14 days of inoculation as compared with extracts of henna and garlic. Moreover, the preventative efficacy partly remained apparent after 14 days of inoculation at all leaf olds tested. In field trials through 2010 and 2011 growing seasons, when the first symptoms of powdery mildew appeared naturally, 1.5% jojoba oil, 2% extract of R. sachalinensis and 1% neem seed oil were sprayed individually twice on grown plants to evaluate their efficacy on controlling powdery mildew, growth and yield of okra. Resulted showed that neem seed oil was the most effective agent and highly decreased the disease severity to 29.92%, recorded the highly curative effect (68.15% and also improved plant growth and pods yield.

    Chagas' disease induced by Trypanosoma cruzi infection is an important cause of mortality and morbidity affecting the cardiovascular system for which presently available therapies are largely inadequate. We previously reported that transforming growth factor β (TGF-β) is implicated in several regulatory aspects of T. cruzi invasion and growth and in host tissue fibrosis. This prompted us to evaluate the therapeutic action of an inhibitor of TGF-β signaling (SB-431542) administered during the acute phase of experimental Chagas' disease. Male Swiss mice were infected intraperitoneally with 104 trypomastigotes of T. cruzi (Y strain) and evaluated clinically for the following 30 days. SB-431542 treatment significantly reduced mortality and decreased parasitemia. Electrocardiography showed that SB-431542 treatment was effective in protecting the cardiac conduction system. By 14 day postinfection, enzymatic biomarkers of tissue damage indicated that muscle injury was decreased by SB-431542 treatment, with significantly lower blood levels of aspartate aminotransferase and creatine kinase. In conclusion, inhibition of TGF-β signaling in vivo appears to potently decrease T. cruzi infection and to prevent heart damage in a preclinical mouse model. This suggests that this class of molecules may represent a new therapeutic agent for acute and chronic Chagas' disease that warrants further clinical exploration. PMID:19738024
