Pharmaceuticals have been reported to be ubiquitously present in surface waters prompting concerns of effects of these bioactive substances. Meanwhile, there is a general scarcity of publicly available ecotoxicological data concerning pharmaceuticals. The aim of this paper was to compile a comprehensive database based on OECD's standardized measured ecotoxicological data and to evaluate if there is generally cause of greater concern with regards to pharmaceutical aquatic toxicological profiles relative to industrial chemicals. Comparisons were based upon aquatic ecotoxicity classification under the United Nations Global Harmonized System for classification and labeling of chemicals (GHS). Moreover, we statistically explored whether the predominant mode-of-action (MOA) for pharmaceuticals is narcosis. We found 275 pharmaceuticals with 569 acute aquatic effect data; 23 pharmaceuticals had chronic data. Pharmaceuticals were found to be more frequent than industrial chemicals in GHS category III. Acute toxicity was predictable (>92%) using a generic (Q)SAR ((Quantitative) Structure Activity Relationship) suggesting a narcotic MOA. Analysis of model prediction error suggests that 68% of the pharmaceuticals have a non-specific MOA. Additionally, the acute-to-chronic ratio (ACR) for 70% of the analyzed pharmaceuticals was below 25 further suggesting a non-specific MOA. Sub-lethal receptor-mediated effects may however have a more specific MOA.

Full Text Available Acute pharyngitis/tonsillitis, which is characterized by inflammation of the posterior pharynx and tonsils, is a common disease. Several viruses and bacteria can cause acute pharyngitis; however, Streptococcus pyogenes (also known as Lancefield group A β-hemolytic streptococci is the only agent that requires an etiologic diagnosis and specific treatment. S. pyogenes is of major clinical importance because it can trigger post-infection systemic complications, acute rheumatic fever, and post-streptococcal glomerulonephritis. Symptom onset in streptococcal infection is usually abrupt and includes intense sore throat, fever, chills, malaise, headache, tender enlarged anterior cervical lymph nodes, and pharyngeal or tonsillar exudate. Cough, coryza, conjunctivitis, and diarrhea are uncommon, and their presence suggests a viral cause. A diagnosis of pharyngitis is supported by the patient's history and by the physical examination. Throat culture is the gold standard for diagnosing streptococcus pharyngitis. However, it has been underused in public health services because of its low availability and because of the 1- to 2-day delay in obtaining results. Rapid antigen detection tests have been used to detect S. pyogenes directly from throat swabs within minutes. Clinical scoring systems have been developed to predict the risk of S. pyogenes infection. The most commonly used scoring system is the modified Centor score. Acute S. pyogenes pharyngitis is often a self-limiting disease. Penicillins are the first-choice treatment. For patients with penicillin allergy, cephalosporins can be an acceptable alternative, although primary hypersensitivity to cephalosporins can occur. Another drug option is the macrolides. Future perspectives to prevent streptococcal pharyngitis and post-infection systemic complications include the development of an anti-Streptococcus pyogenes vaccine.

Full Text Available Alert level frameworks advise agencies on a sequence of monitoring and management actions, and are implemented so as to reduce the risk of the public coming into contact with hazardous substances. Their effectiveness relies on the detection of the hazard, but with many systems not receiving any regular monitoring, pollution events often go undetected. We developed toxicological risk assessment models for acute and chronic exposure to pollutants that incorporate the probabilities that the public will come into contact with undetected pollution events, to identify the level of risk a system poses in regards to the pollutant. As a proof of concept, we successfully demonstrated that the models could be applied to determine probabilities of acute and chronic illness types related to recreational activities in waterbodies containing cyanotoxins. Using the acute model, we identified lakes that present a ‘high’ risk to develop Day Away From Work illness, and lakes that present a ‘low’ or ‘medium’ risk to develop First Aid Cases when used for swimming. The developed risk models succeeded in categorising lakes according to their risk level to the public in an objective way. Modelling by how much the probability of public exposure has to decrease to lower the risks to acceptable levels will enable authorities to identify suitable control measures and monitoring strategies. We suggest broadening the application of these models to other contaminants.

Consumer satisfaction with the acute-care experience could reasonably be expected to be higher amongst those treated in the private sector compared to those treated in the public sector given the former relies on high-level satisfaction of its consumers and their subsequent recommendations to thrive. The primary aims of this study were to determine, in a knee or hip arthroplasty cohort, if surgery in the private sector predicts greater overall satisfaction with the acute-care experience and greater likelihood to recommend the same hospital. A secondary aim was to determine whether satisfaction across a range of service domains is also higher in the private sector. A telephone survey was conducted 35 days post-surgery. The hospital cohort comprised eight public and seven private high-volume arthroplasty providers. Consumers rated overall satisfaction with care out of 100 and likeliness to recommend their hospital on a 5-point Likert scale. Additional Likert-style questions were asked covering specific service domains. Generalized estimating equation models were used to analyse overall satisfaction (dichotomised as ≥ 90 or sector reporting the best Likert response for each individual domain were compared using non-parametric tests. 457 survey respondents (n = 210 private) were included. Less patient-reported joint impairment pre-surgery [OR 1.03 (95% CI 1.01-1.05)] and absence of an acute complication (OR 2.13 95% CI 1.41-3.23) significantly predicted higher overall satisfaction. Hip arthroplasty [OR 1.84 (1.1-2.96)] and an absence of an acute complication [OR 2.31 (1.28-4.17] significantly predicted greater likelihood for recommending the hospital. The only care domains where the private out-performed the public sector were hospitality (46.7 vs 35.6%, p private sector are not more satisfied with their acute-care experience nor are they more likely to recommend their hospital provider. Rather, avoidance of complications in either sector appears to result in

FDG PET in hyperglycaemic subjects often suffers from limited statistical image quality, which may hamper visual and quantitative evaluation. In our study the following insulin bolus protocol is proposed for acute correction of hyperglycaemia (> 7.0 mmol/l) in brain FDG PET. (i) Intravenous bolus injection of short-acting insulin, one I.E. for each 0.6 mmol/l blood glucose above 7.0. (ii) If 20 min after insulin administration plasma glucose is {<=} 7.0 mmol/l, proceed to (iii). If insulin has not taken sufficient effect step back to (i). Compute insulin dose with the updated blood glucose level. (iii) Wait further 20 min before injection of FDG. (iv) Continuous supervision of the patient during the whole scanning procedure. The potential of this protocol for improvement of image quality in brain FDG PET in hyperglycaemic subjects was evaluated by computer simulations within the Sokoloff model. A plausibility check of the prediction of the computer simulations on the magnitude of the effect that might be achieved by correction of hyperglycaemia was performed by retrospective evaluation of the relation between blood glucose level and brain FDG uptake in 89 subjects in whom FDG PET had been performed for diagnosis of Alzheimer's disease. The computer simulations suggested that acute correction of hyperglycaemia according to the proposed bolus insulin protocol might increase the FDG uptake of the brain by up to 80%. The magnitude of this effect was confirmed by the patient data. The proposed management protocol for acute correction of hyperglycaemia with insulin has the potential to significantly improve the statistical quality of brain FDG PET images. This should be confirmed in a prospective study in patients. (orig.)

It is unclear whether the management of stroke has been improved since the Japanese Guidelines for the Management of Stroke (2004) was published. The aim of the present study was to clarify changes in the management for acute ischemic stroke after publication of the Japanese Guidelines. We investigated the management of patients with acute ischemic stroke in nine hospitals belonging to the committee of Toyama Acute Ischemic Stroke Study, before and after publication of the Japanese Guidelines for the Management of Stroke (2004). Two-hundred and ninety-three acute ischemic stroke patients were registered in 2003 and 237 in 2006, respectively. The percentage of lacunar stroke was 39%, 37%, atherothrombotic infarction; 28%, 30%, cardioembolic stroke (CE); 21%, 22%, and others; 12%, 11%, respectively. The ratio of CE patients who were admitted within 3 hours of onset was significantly increased from 34% in 2003 to 57% in 2006. Although 74 patients (31%) with any clinical type were admitted within 3 hours of onset, thrombolytic therapy with tissue plasminogen activator (rt-PA) was administered to only 5 patients (2.1%) in 2006. Diffusion weighted images became available in all hospitals, and were more frequently used for diagnosis of acute ischemic stroke in 92% of patients in 2006 as compared to 59% in 2003. Ischemic lesions were more frequently detected before the start of treatment in 52% of patients in 2006 as compared to 43% in 2003. After the Japanese Guidelines for the Management of Stroke (2004) was published, the treatment of acute ischemic stroke patients appeared to follow this guideline in many patients. Thrombolytic therapy with rt-PA, however, was performed in very few patients. (author)

Full Text Available The aim of this study is to measure Turkish government employees’ awareness of cyber security and cyber space elements. Participants were 71 Turkish public employees working for various ministries. Both qualitative and quantitative research methods were used to get the most detailed information from the participants. A survey was administered to cyber security officers in chosen state institutions. For qualitative research, open-ended questions were administered to the participants. Reliability and validity issues were established for both surveys. Results show that employees have enough information about cyber security and cyber warfare. Findings clearly suggests that cyber defense policy should be planned in coordination with other state institutions and experiences should be shared. In order to create feasible and realistic cyber security policy at institutional level, experts at cyber security must be trained, hired and help must be requested from specialized individuals and institutions. This study recommends that rapid reaction teams (RRT should be established to take care of cyber systems, to react against cyber breaches in time, to alert staff for cyber-attacks in order to establish effective recovery.

Full Text Available Acute biliary pancreatitis is one of the major causes of acute pancreatitis.Gallstones, biliary sludge and microlithiasis, especially in pancreatitis without detectable reason, can be the cause of acute pancreatitis. Acute biliary pancreatitis has many controversions in the literature, and its classification and guidelines are being updated very frequently. Atlanta classifications which determine the definitions and guidelines about acute pancreatitis were renewed and published in 2013. It has various clinical aspects, ranging from a mild form which is easily treated, to a severe form that causes complications leading to mortality. The pathogenesis of this disease has not been fully elucidated and several theories have been suggested. New scoring systems and laboratory methods such as proteomics have been suggested for both diagnosis and to predict disease severity, and research on these topics is still in progress. Novel therapeutic approaches with technological developments such as ERCP, ES, MRCP, and EUS are also suggested.

In 2015 a microbiology team in Bristol joined a European research project that aims to develop new antibiotics to fight drug resistant infections. The microbiology team were convinced of the benefits of patient and public involvement, but had found it difficult to find former patients to work with on earlier microbiology research. This paper describes how the team overcame this challenge to successfully recruit a PPI panel to develop PPI within the European project.The advice from people with experience in public involvement was to decide what criteria were desirable for panel membership, think about what the work of the panel might involve and how long the project will go on. The team decided that experience of suffering a serious acute infection would qualify people to comment on this project. Next, the team needed to identify ways of finding people to join the PPI panel.The microbiology research team tried different ways to approach potential panel members. These included distributing flyers at public research events, sending emails to potentially interested people, posting a message on the hospital Facebook page and approaching eligible people known to the team. A direct approach was the most successful method - either by email, mail or in person. Ultimately 16 people were selected to form the panel. Key factors for success were planning what the work of the panel might be, perseverance despite early lack of success, and one person having overall responsibility for setting up the panel, with the support of the whole team. Background In 2015 the microbiology research team became involved in a large European programme of research aiming to bring new antimicrobial drugs onto the market to combat the increasing problem of multi-drug resistant infection. With the purpose of developing patient and public involvement (PPI) in this project, the team decided to recruit a PPI panel to work with. The microbiology team had previously worked with a PPI panel on other

History and evolution of surveillance in public health

Full Text Available The modern concept of surveillance has evolved over the centuries. Public health surveillance provides the scientific database essential for decision making and appropriate public health action. It is considered as the best public health tool to prevent the occurrence of epidemics and is the backbone of public health programs and provides information so that effective action can be taken in controlling and preventing diseases of public health importance. This article reviews the history of evolution of public health surveillance from historical perspective: from Hippocrates, Black Death and quarantine, recording of vital events for the first time, first field investigation, legislations that were developed over time and modern concepts in public health surveillance. Eradication of small pox is an important achievement in public health surveillance but the recent Severe Acute Respiratory Syndrome (SARS and Influenza pandemics suggest still there is a room for improvement. Recently new global disease surveillance networks like FluNet and DengueNet were developed as internet sites for monitoring influenza and dengue information. In spite of these developments, global public health surveillance still remains unevenly distributed. There is a need for increased international cooperation to address the global needs of public health surveillance.

Pharmacy services at admission and discharge in adult, acute, public hospitals in Ireland.

OBJECTIVES: to describe hospital pharmacy involvement in medication management in Ireland, both generally and at points of transfer of care, and to gain a broad perspective of the hospital pharmacy workforce. METHODS: a survey of all adult, acute, public hospitals with an accident and emergency (A&E) department (n = 36), using a semi-structured telephone interview. KEY FINDINGS: there was a 97% (n = 35) response rate. The majority (n = 25, 71.4%) of hospitals reported delivery of a clinical pharmacy service. On admission, pharmacists were involved in taking or verifying medication histories in a minority (n = 15, 42.9%) of hospitals, while few (n = 6,17.1%) deployed staff to the A&E\\/acute medical admissions unit. On discharge, the majority (n = 30,85.7%) did not supply any take-out medication, a minority (n =5,14.3%) checked the discharge prescription, 51.4% (n = 18) counselled patients, 42.9% (n = 15) provided medication compliance charts and one hospital (2.9%) communicated with the patient\\'s community pharmacy. The number of staff employed in the pharmacy department in each hospital was not proportionate to the number of inpatient beds, nor the volume of admissions from A&E. There were differences identified in service delivery between hospitals of different type: urban hospitals with a high volume of admissions from A&E were more likely to deliver clinical pharmacy. CONCLUSIONS: the frequency and consistency of delivering pharmacy services to facilitate medication reconciliation at admission and discharge could be improved. Workforce constraints may inhibit service expansion. Development of national standards of practice may help to eliminate variation between hospitals and support service development.

Pharmaceutical Sponsorship Bias Influences Thrombolytic Literature in Acute Ischemic Stroke

Full Text Available Background: The efficacy of thrombolytic therapy for acute ischemic stroke remains controversial in Emergency Medicine and has not been fully endorsed by either the American College of Emergency Physicians or the American Academy of emergency medicine. A growing recognition exists of the influence of pharmaceutical sponsorship on the reported findings of published clinical trials. Sponsorship bias has been suggested as a potential criticism of the literature and guidelines favoring thrombolytic therapy. Objective: The objective of this study is to review the most influential literature regarding thrombolytic therapy for acute ischemic stroke and document the presence or absence of pharmaceutical sponsorship. Methods: A publication-citation analysis was performed to identify the most frequently cited articles pertaining to thrombolytic therapy for acute ischemic stroke. Identified articles were reviewed for disclosures of pharmaceutical funding. Results: Of the 20 most-cited articles pertaining to thrombolytic therapy for acute stroke, 17 (85% disclosed pharmaceutical sponsorship. These disclosures range from general sponsorship to direct employment of authors by pharmaceutical companies. Conclusion: An overwhelming predominance of the most influential literature regarding thrombolytic therapy for acute ischemic stroke is susceptible to sponsorship bias. This potential bias may provide a basis for physician concern regarding the efficacy and safety of thrombolytic therapy. Further, large, independent, placebo-controlled studies may be required to guide therapy and professional guidelines definitively for acute ischemic stroke. [West J Emerg Med. 2011;12(4:435–441.

A key step in informing mental health resource allocation is to identify the predictors of service utilisation and costs. This project aims to identify the predictors of mental health-related acute service utilisation and treatment costs in the year following an acute public psychiatric hospital admission. A dataset containing administrative and routinely measured outcome data for 1 year before and after an acute psychiatric admission for 1757 public mental health patients was analysed. Multivariate regression models were developed to identify patient- and treatment-related predictors of four measures of service utilisation or cost: (a) duration of index admission; and, in the year after discharge from the index admission (b) acute psychiatric inpatient bed-days; (c) emergency department (ED) presentations; and (d) total acute mental health service costs. Split-sample cross-validation was used. A diagnosis of psychosis, problems with living conditions and prior acute psychiatric inpatient bed-days predicted a longer duration of index admission, while prior ED presentations and self-harm predicted a shorter duration. A greater number of acute psychiatric inpatient bed-days in the year post-discharge were predicted by psychosis diagnosis, problems with living conditions and prior acute psychiatric inpatient admissions. The number of future ED presentations was predicted by past ED presentations. For total acute care costs, diagnosis of psychosis was the strongest predictor. Illness acuity and prior acute psychiatric inpatient admission also predicted higher costs, while self-harm predicted lower costs. The development of effective models for predicting acute mental health treatment costs using existing administrative data is an essential step towards a workable activity-based funding model for mental health. Future studies would benefit from the inclusion of a wider range of variables, including ethnicity, clinical complexity, cognition, mental health legal status

Acute agitation psychiatric emergencies as frequently occur in psychiatric as well as in non-psychiatric settings, such as general hospitals, specialized clinics, emergency services and private practices. Psychiatric emergencies can be life-threatening and necessitate immediate treatment. This article presents the core symptomatology, differential diagnoses and treatment options of acute agitation emergencies. Case control studies and reliable data regarding prevalence and treatment of acute agitation in psychiatric and general hospitals or private practices are sparse. Existing evidence suggests that optimization of diagnosis and therapy of psychiatric emergencies, such as acute agitation is warranted. Treatment of acute agitation, psychological distress and other psychiatric emergencies are highly demanding regarding psychiatric expertise and concerning the personality and behavior of the therapist. The basis of therapy comprises the ability to form a stable and trustworthy relationship with the patient as well as to patiently calm down agitated patients. Unambiguous and rapid decision-making that takes effective pharmacological treatment options into account usually leads to swift amelioration of the acute symptomatology.

The Acute Psychological Trauma (APT) Study was a collaboration between an acute care hospital, a specialized multidisciplinary program designed to meet the mental health needs of injured workers, and a large urban public transit system. The overall purpose was to evaluate a Best Practices Intervention (BPI) for employees affected by acute psychological trauma compared to a Treatment as Usual (TAU) group. The specific purpose is to discuss facilitators and barriers that were recognized in implementing and carrying out mental health research in a workplace setting. Over the course of the APT study, a joint implementation committee was responsible for day-to-day study operations and made regular observations on the facilitators and barriers that arose throughout the study. The facilitators to this study included the longstanding relationships among the partners, increased recognition for the need of mental health research in the workplace, and the existence of a community advisory committee. The significant barriers to doing this study of mental health research in the workplace included differences in organizational culture, inconsistent union support, co-interventions, and stigma. Researchers and funding agencies need to be flexible and provide additional resources in order to overcome the barriers that can exist doing workplace mental health research.

Experiences of Public Doctors on Managing Work Difficulties and Maintaining Professional Enthusiasm in Acute General Hospitals: A Qualitative Study.

Overseas studies suggest that 10-20% of doctors are depressed, 30-45% have burnout, and many report dissatisfaction with work-life balance. A local study on public doctors showed that 31.4% of the respondents satisfied the criteria for high burnout. Young, but moderately experienced doctors who need to work shifts appeared most vulnerable. This study aims to explore the experiences of those public doctors who have managed their work difficulties and maintained professional enthusiasm for references in medical education and continuing professional training. Ten public doctors with reputation were invited respectively from three acute general hospitals for an in-depth interview. Interviews were audio recorded and transcribed. Content analysis was carried out to identify major themes in relation to the research questions. Three themes emerging from difficulties encountered were (1) managing people, mostly are patients, followed by colleagues and then patients' relatives; (2) constraints at work, include time and resources; and (3) managing self with decision-making within a short time. Three themes generating from managing work difficulties included (1) self-adjustment with practicing problem solving and learning good communication appeared more frequently, followed by maintaining a professional attitude and accumulating clinical experiences; (2) seeking help from others; and (3) organizational support is also a theme though it is the least mentioned. Four themes emerging from maintaining work enthusiasm were (1) personal conviction and discipline: believing that they are helping the needy, having the sense of vocation and support from religion; disciplining oneself by continuing education, maintaining harmonious family relationship and volunteer work. (2) Challenging work: different challenging natures of their job. (3) Positive feedback from patients: positive encounters with patients keep a connectedness with their clients.

2007-06-01

Full Text Available Abstract Background Many people now seek alternative methods of weight loss. The internet provides a readily available source of weight reduction products, the ingredients of which are often unclear. The authors describe a case of acute hepatitis in a 20 year old woman caused by such a product purchased over the internet. Case Presentation A 20-year old woman presented with a two day history of abdominal pain, vomiting and jaundice. There were no identifiable risk factors for chronic liver disease. Liver function tests demonstrated an acute hepatitis (aminoaspartate transaminase 1230 IU/L. A chronic liver disease screen was negative. The patient had started a weight loss product (Pro-Lean, purchased over the internet two weeks prior to presentation. The patient was treated conservatively, and improved. The sequence of events suggests an acute hepatitis caused by an herbal weight loss product. Conclusion This case report highlights the dangers of weight loss products available to the public over the internet, and the importance of asking specifically about alternative medicines in patients who present with an acute hepatitis.

In vitro infection of pupae with Israeli acute paralysis virus suggests disturbance of transcriptional homeostasis in honey bees (Apis mellifera.

Directory of Open Access Journals (Sweden)

Humberto F Boncristiani

Full Text Available The ongoing decline of honey bee health worldwide is a serious economic and ecological concern. One major contributor to the decline are pathogens, including several honey bee viruses. However, information is limited on the biology of bee viruses and molecular interactions with their hosts. An experimental protocol to test these systems was developed, using injections of Israeli Acute Paralysis Virus (IAPV into honey bee pupae reared ex-situ under laboratory conditions. The infected pupae developed pronounced but variable patterns of disease. Symptoms varied from complete cessation of development with no visual evidence of disease to rapid darkening of a part or the entire body. Considerable differences in IAPV titer dynamics were observed, suggesting significant variation in resistance to IAPV among and possibly within honey bee colonies. Thus, selective breeding for virus resistance should be possible. Gene expression analyses of three separate experiments suggest IAPV disruption of transcriptional homeostasis of several fundamental cellular functions, including an up-regulation of the ribosomal biogenesis pathway. These results provide first insights into the mechanisms of IAPV pathogenicity. They mirror a transcriptional survey of honey bees afflicted with Colony Collapse Disorder and thus support the hypothesis that viruses play a critical role in declining honey bee health.

Schreck, David M; Fishberg, Robert D

2014-01-01

Objective A new cardiac “electrical” biomarker (CEB) for detection of 12-lead electrocardiogram (ECG) changes indicative of acute myocardial ischemic injury has been identified. Objective was to test CEB diagnostic accuracy. Methods This is a blinded, observational retrospective case-control, noninferiority study. A total of 508 ECGs obtained from archived digital databases were interpreted by cardiologist and emergency physician (EP) blinded reference standards for presence of acute myocardial ischemic injury. CEB was constructed from three ECG cardiac monitoring leads using nonlinear modeling. Comparative active controls included ST voltage changes (J-point, ST area under curve) and a computerized ECG interpretive algorithm (ECGI). Training set of 141 ECGs identified CEB cutoffs by receiver-operating-characteristic (ROC) analysis. Test set of 367 ECGs was analyzed for validation. Poor-quality ECGs were excluded. Sensitivity, specificity, and negative and positive predictive values were calculated with 95% confidence intervals. Adjudication was performed by consensus. Results CEB demonstrated noninferiority to all active controls by hypothesis testing. CEB adjudication demonstrated 85.3–94.4% sensitivity, 92.5–93.0% specificity, 93.8–98.6% negative predictive value, and 74.6–83.5% positive predictive value. CEB was superior against all active controls in EP analysis, and against ST area under curve and ECGI by cardiologist. Conclusion CEB detects acute myocardial ischemic injury with high diagnostic accuracy. CEB is instantly constructed from three ECG leads on the cardiac monitor and displayed instantly allowing immediate cost-effective identification of patients with acute ischemic injury during cardiac rhythm monitoring.

Increased accountability and growing fiscal limitations in global health care continue to challenge how occupational therapy practices are undertaken. Little is known about how these changes affect current practice in acute hospital settings. This article reviews the relevant literature to further understanding of occupational therapy practice in acute physical hospital settings. A scoping review of five electronic databases was completed using the keywords Occupational therapy, acute hospital settings/acute physical hospital settings, acute care setting/acute care hospital setting, general medicine/general medical wards, occupational therapy service provision/teaching hospitals/tertiary care hospitals. Criteria were applied to determine suitability for inclusion and the articles were analysed to uncover key themes. In total 34 publications were included in the review. Analysis of the publications revealed four themes: (1) Comparisons between the practice of novice and experienced occupational therapists in acute care (2) Occupational therapists and the discharge planning process (3) Role of occupation in the acute care setting and (4) Personal skills needed and organisation factors affecting acute care practice. The current literature has highlighted the challenges occupational therapists face in practicing within an acute setting. Findings from this review enhance understanding of how occupational therapy department managers and educators can best support staff that practise in acute hospital settings. © 2015 Occupational Therapy Australia.

2004-01-01

According to the best of our knowledge this is the first publication in medical literature about the acute intoxication with fenspiride. The two cases of a young female patients, intoxicated with Eurespal, were described. The orthostatic hypotonia with the blood pressure about 105-115/70 mm Hg in the horizontal position and 70-80/40 mm Hg in the sitting position was dominating. The heart rate was 100-110/min. when lying and 130-140/min. when sitting. The main symptoms were probably caused by inhibition of alpha1 adrenergic receptors. Main clinical manifestations make us reconsider the opinion about safety of fenspiride especially after acute intoxication.

2017-09-01

Full Text Available The paper considers the ways to optimize financing public higher education institutions of Ukraine. Public higher education institutions acutely feel the lack of financial resources. The study describes that it is necessary to reform the models, methods and forms of financing higher education institutions. The paper explains the impact of autonomy of higher education institutions on their development. The autonomy level of university determines the possibilities for diversification from additional sources. The results found that more autonomy of higher education institutions will allow them effectively generate and use financial resources. The review outlines the diversification of financial resources public universities. One of the key factors of the university success is to implement the diversification strategy into the overall academic strategy and mission of the higher education institution. The analysis recommends the performance-based funding system and public higher education institutions achieve certain performance indicators. The performance-based funding system will promote higher competitiveness of education institutions and improve the quality of higher education in general. The conclusions suggest the development trends of financing public higher education institutions of Ukraine.

The role of warning behaviors in threat assessment: an exploration and suggested typology.

Science.gov (United States)

Reid Meloy, J; Hoffmann, Jens; Guldimann, Angela; James, David

2012-01-01

The concept of warning behaviors offers an additional perspective in threat assessment. Warning behaviors are acts which constitute evidence of increasing or accelerating risk. They are acute, dynamic, and particularly toxic changes in patterns of behavior which may aid in structuring a professional's judgment that an individual of concern now poses a threat - whether the actual target has been identified or not. They require an operational response. A typology of eight warning behaviors for assessing the threat of intended violence is proposed: pathway, fixation, identification, novel aggression, energy burst, leakage, directly communicated threat, and last resort warning behaviors. Previous research on risk factors associated with such warning behaviors is reviewed, and examples of each warning behavior from various intended violence cases are presented, including public figure assassination, adolescent and adult mass murder, corporate celebrity stalking, and both domestic and foreign acts of terrorism. Practical applications and future research into warning behaviors are suggested. Copyright © 2011 John Wiley & Sons, Ltd.

In some cases of acute pancreatitis no cause can be identified. An etiologic role of Yersinia enterocolitica type 3 was suggested in two previous reports. A case is now presented which supports this hypothesis by simultaneity of reactive phase of yersiniosis and an acute attack of pancreatitis...... of otherwise unknown cause. Although the coincidence may have been fortuitous, the pattern common to this and the earlier published cases suggests that it may yield a further clue to an etiologic understanding of acute pancreatitis....

Acute kidney injury following immersion or near-drowning is rarely described and no data from Malaysia have been found. We report a case of acute kidney injury following a near-drowning event. A 20-year-old man who recovered from near-drowning in a swimming pool 5 days earlier presented to our clinic with abdominal pain, anorexia, nausea and polyuria. Dipstick urinalysis showed a trace of blood. The serum creatinine level was 10-fold higher than the normal range. A bedside ultrasound showed features suggestive of acute tubular necrosis. He is then referred to the hospital with the diagnosis of acute kidney injury with the possibility of acute tubular necrosis secondary to near-drowning. We suggest that any patient presenting after immersion or near-drowning to be should assessed for potential acute kidney injury.

Acute eosinophilic pneumonia is one of a recently described idiopathic eosinophilic lung disease, which differs from chronic eosinophilic pneumonia. Patients with acute eosinophilic pneumonia develop acute onset of dyspnea, hypoxemia, diffuse pulmonary infiltrates and pleural effusion on chest radiograph, and show an increase in number of eosinophils in bronchoalveolar lavage fluid or lung biopsy specimen. Prompt and complete response to corticosteroid therapy without any recurrence is characteristically seen in patient with this disease. Although the etiology of acute eosinophilic pneumonia is not known, it has been suggested to be related to a hypersensitivity phenomenon to an unidentified inhaled antigen. We report four cases of acute eosinophilic pneumonia presented with acute onset of dyspnea, diffuse pulmonary infiltrates on chest radiograph, and eosinophilia in bronchoalveolar lavage fluid in previously healthy adults.

Policymaking to preserve privacy in disclosure of public health data: a suggested framework.

Science.gov (United States)

Mizani, Mehrdad A; Baykal, Nazife

2015-03-01

Health organisations in Turkey gather a vast amount of valuable individual data that can be used for public health purposes. The organisations use rigid methods to remove some useful details from the data while publishing the rest of the data in a highly aggregated form, mostly because of privacy concerns and lack of standardised policies. This action leads to information loss and bias affecting public health research. Hence, organisations need dynamic policies and well-defined procedures rather than a specific algorithm to protect the privacy of individual data. To address this need, we developed a framework for the systematic application of anonymity methods while reducing and objectively reporting the information loss without leaking confidentiality. This framework acts as a roadmap for policymaking by providing high-level pseudo-policies with semitechnical guidelines in addition to some sample scenarios suitable for policymakers, public health programme managers and legislators.

Aoki, Nobuhiko; Kaneshi, Kunio; Mizuguchi, Masashi; Kurihara, Eiji.

1983-01-01

We experienced three cases of acute toxic encephalopathy, including a case of probable Reye syndrome, which had similar and unique CT findings in their acute stage; symmetrical low density area in the thalamus and the dentate nucleus, followed by changes in cerebellar hemispheres and around lateral ventricles. The CT findings, common to probable Reye syndrome and other acute toxic encephalopathy, may suggest the possibility of similar pathogenesis of brain damage in both disorders. The authors propose that present cases are a new subgroup in acute toxic encephalopathy, because of their similar and unique CT features. (author)

Where did the acute medical trainees go? A review of the career pathways of acute care common stem acute medical trainees in London.

2016-10-01

Acute care common stem acute medicine (ACCS AM) training was designed to develop competent multi-skilled acute physicians to manage patients with multimorbidity from 'door to discharge' in an era of increasing acute hospital admissions. Recent surveys by the Royal College of Physicians have suggested that acute medical specialties are proving less attractive to trainees. However, data on the career pathways taken by trainees completing core acute medical training has been lacking. Using London as a region with a 100% fill rate for its ACCS AM training programme, this study showed only 14% of trainees go on to higher specialty training in acute internal medicine and a further 10% to pursue higher medical specialty training with dual accreditation with internal medicine. 16% of trainees switched from ACCS AM to emergency medicine or anaesthetics during core ACCS training, and intensive care medicine proved to be the most popular career choice for ACCS AM trainees (21%). The ACCS AM training programme therefore does not appear to be providing what it was set out to do and this paper discusses the potential causes and effects. © Royal College of Physicians 2016.

[Enteroviruses responsible for acute hemorrhagic conjunctivitis].

Science.gov (United States)

Lévêque, N; Huguet, P; Norder, H; Chomel, J-J

2010-04-01

Acute hemorrhagic conjunctivitis (AHC) is an epidemic form of highly contagious conjunctivitis, characterized by conjunctival hemorrhages. The first AHC outbreak was described in 1969 in Ghana, West Africa, and was called Apollo disease, from the Apollo landing on the moon. This outbreak was caused by Enterovirus 70 (EV70) together with a Coxsackievirus A24 (CVA24v) variant, which are the major etiological agents involved in AHC outbreaks worldwide. AHC is known to be directly transmitted by close person-to-person contact or indirectly through soiled ophthalmological materials or unsafe recreational water. Recently, a possible airborne virus spread was suggested which could explain the high transmission rate of the disease. In the absence of a specific antiviral therapy, a rapid diagnosis of the causative agent is required to distinguish AHC due to enteroviruses from other ocular infectious diseases, for there are active drugs, or to quickly implement proper public health measures to limit the extension of the outbreak. However, virus identification remains difficult and time-consuming. Moreover, virological diagnosis is difficult to implement in developing countries where AHC has recently become a major problem for public health. Copyright 2009 Elsevier Masson SAS.

2015-04-01

Full Text Available Bilateral acute iris transillumination (BAIT is a relatively new clinical entity characterized by bilateral acute loss of iris pigment epithelium, iris transillumination, pigment dispersion in the anterior chamber, and sphincter paralysis. We report the case of a 30-year-old male who was initially diagnosed with acute iridocyclitis in a different clinic and treated with topical and systemic corticosteroids. He was referred to our clinic to seek another opinion because his symptoms did not improve. An ocular examination revealed bilateral pigment dispersion into the anterior chamber, diffuse iris transillumination, pigment dusting on the anterior lens capsule, atonic and distorted pupils, and increased intraocular pressure, suggesting a diagnosis of BAIT rather than iridocyclitis. Clinicians should be aware of the differential diagnosis of syndromes associated with pigment dispersion from iridocyclitis to avoid aggressive anti-inflammatory therapy and detailed investigation for uveitis.

2013-04-01

We investigated whether occupational role stress is associated with differential levels of the stress hormone cortisol in response to acute psychosocial stress. Forty-three medication-free nonsmoking men aged between 22 and 65 years (mean ± SEM: 44.5 ± 2) underwent an acute standardized psychosocial stress task combining public speaking and mental arithmetic in front of an audience. We assessed occupational role stress in terms of role conflict and role ambiguity (combined into a measure of role uncertainty) as well as further work characteristics and psychological control variables including time pressure, overcommitment, perfectionism, and stress appraisal. Moreover, we repeatedly measured salivary cortisol and blood pressure levels before and after stress exposure, and several times up to 60 min thereafter. Higher role uncertainty was associated with a more pronounced cortisol stress reactivity (p = .016), even when controlling for the full set of potential confounders (p stress reactivity was not associated with role uncertainty. Our findings suggest that occupational role stress in terms of role uncertainty acts as a background stressor that is associated with increased HPA-axis reactivity to acute stress. This finding may represent a potential mechanism regarding how occupational role stress may precipitate adverse health outcomes.

A. N. Lodyagin

2008-01-01

Full Text Available Objective: to evaluate the efficiency of methods for diagnosing and treating critically ill patients with acute respiratory failure (ARF in acute poisoning by neurotropic substances. Subjects and methods. Two hundred and thirty-three patients with acute severe intoxication with neurotropic poisons were examined. All the patients were admitted for toxic-hypoxic coma and ARF; in this connection all the patients underwent artificial ventilation (AV. The patients were divided into 3 groups: 1 those in whom the traditional treatments (AV, detoxifying therapy, and infusional and cardiotropic support could restore the basic parameters of vital functions, as judged from the recovered oxygenation index; these patients had no metabolic shifts; 2 those who had signs of pulmonary hyperhydration, low cardiac output and moderate metabolic disorders, as suggested by elevated lactate levels; 3 seriously ill patients in whom the interval between the time of poisoning to care delivery was more than 20 hours; the patients of this group had the most significant metabolic disorders. Results. Correction of ARF in critically ill patients with acute poisoning should include, in addition to the rational parameters of AV and detoxifying therapy, agents for targeted therapy for sequels of hypoxia and energy deficiency states. For maximally rapid and effective oxygen transport recovery, the addition of perfluorane to the complex therapy cardinally improves the results of treatment and reduces mortality rates. Conclusion. The complexity of the pathogenesis of ARF and its sequels is a ground for diagnosing and correcting not only ventilation disturbances, but also pulmonary microcirculatory disorders and metabolic disturbances. Key words: acute intoxication with neu-rotropic poisons, acute respiratory failure, pulmonary hyperhydration, hypoxia, metabolic disturbances.

The purpose of this article is to describe and illustrate the CT findings of acute cholecystitis and its complications. CT findings suggesting acute cholecystitis should be interpreted with caution and should probably serve as justification for further investigation with abdominal ultrasound. CT has a relatively high negative predictive value, and acute cholecystitis is unlikely in the setting of a negative CT. Complications of acute cholecystitis have a characteristic CT appearance and include necrosis, perforation, abscess formation, intraluminal hemorrhage, and wall emphysema.

This study describes clinical, laboratory, and electrodiagnostic features of a severe acute axonal polyneuropathy common to patients with acute nutritional deficiency in the setting of alcoholism, bariatric surgery (BS), or anorexia. Retrospective analysis of clinical, electrodiagnostic, and laboratory data of patients with acute axonal neuropathy. Thirteen patients were identified with a severe, painful, sensory or sensorimotor axonal polyneuropathy that developed over 2-12 weeks with sensory ataxia, areflexia, variable muscle weakness, poor nutritional status, and weight loss, often with prolonged vomiting and normal cerebrospinal fluid protein. Vitamin B6 was low in half and thiamine was low in all patients when obtained before supplementation. Patients improved with weight gain and vitamin supplementation, with motor greater than sensory recovery. We suggest that acute or subacute axonal neuropathy in patients with weight loss or vomiting associated with alcohol abuse, BS, or dietary deficiency is one syndrome, caused by micronutrient deficiencies.

2014-08-01

Terbinafine is an effective antimicrobial agent against dermatophytes, cryptococcus and other fungi. It is the preferred drug to treat onychomycosis. However, severe acute hepatitis from oral terbinafine administration has been recently reported. To describe a representative case, and review the literature regarding the best evidence on treatment and prognosis of severe acute hepatitis caused by oral terbinafine. The literature was searched for publications on severe hepatitis caused by terbinafine using MEDLINE, China Biology Medicine Disc, and the VIP Medical Information Resource System. Related references were searched manually. Seventeen English and three Chinese references of case reports were included after eliminating duplicate publications. No randomized control studies were found. Liver enzyme levels were found to have been increased significantly. Abdominal ultrasound demonstrated cholestasis. Severe acute liver injury is a known, but unusual complication of terbinafine exposure. The prognosis is often good with appropriate treatment. Liver function assessment before treatment and periodic monitoring 4-6 weeks after initiation of treatment is recommended.

2014-01-01

Background QT dispersion (QTd) has been proposed as an indirect ECG measure of heterogeneity of ventricular repolarization. The predictive value of QTd in acute stroke remains controversial. We aimed to clarify the relationship between QTd and acute stroke and stroke prognosis. Methods A systematic review of the literature was performed using pre-specified medical subjects heading (MeSH) terms, Boolean logic and the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Eligible studies (a) included ischemic or hemorrhagic stroke and (b) provided QTd measurements. Results Two independent reviewers identified 553 publications. Sixteen articles were included in the final analysis. There were a total of 888 stroke patients: 59% ischemic and 41% hemorrhagic. There was considerable heterogeneity in study design, stroke subtypes, ECG assessment-time, control groups and comparison groups. Nine studies reported a significant association between acute stroke and baseline QTd. Two studies reported that QTd increases are specifically related to hemorrhagic strokes, involvement of the insular cortex, right-side lesions, larger strokes, and increases in 3, 4-dihydroxyphenylethylene glycol in hemorrhagic stroke. Three studies reported QTd to be an independent predictor of stroke mortality. One study each reported increases in QTd in stroke patients who developed ventricular arrhythmias and cardiorespiratory compromise. Conclusions There are few well-designed studies and considerable variability in study design in addressing the significance of QTd in acute stroke. Available data suggest that stroke is likely to be associated with increased QTd. While some evidence suggests a possible prognostic role of QTd in stroke, larger and well-designed studies need to confirm these findings. PMID:25282188

Data regarding thrombolysis for acute ischemic stroke in Asia are scarce and only a small percentage of patients are thrombolysed. The dose of intravenous tissue plasminogen activator (IV-tPA) in Asia remains controversial. Case-controlled observation studies in Asia included only Japanese patients and suggested the clinical efficacy and safety of low-dose IV-tPA (0.6 mg/kg body weight; max 60 mg) comparable to standard dose (0.9 mg/kg body weight; max. 90 mg). Reduced treatment cost, lower symptomatic intracerebral hemorrhage risk and comparable efficacy encouraged many Asian centers to adopt low-dose or even variable-dose IV-tPA regimens. We evaluated various Asian thrombolysis studies and compared with SITS-MOST registry and NINDS trial. We included the published studies on acute ischemic stroke thrombolysis in Asia. Unadjusted relative risks and 95% Confidence intervals were calculated for each study. Pooled estimates from random effects models were used because the tests for heterogeneity were significant. We found only 18 publications regarding acute ischemic stroke thrombolysis in Asia that included total of 9300 patients. Owing to ethnic differences, stroke severity, small number of cases in individual reports, outcome measures and tPA dose regimes, it is difficult to compare these studies. Functional outcomes were almost similar (to Japanese studies) when lower-dose IV-tPA was used in non-Japanese populations across Asia. Interestingly, with standard dose IV-tPA, considerably better functional outcomes were observed, without increasing symptomatic intracerebral hemorrhage rates. Variable dose regimens of IV-tPA are used across Asia without any reliable or established evidence. Establishing a uniform IV-tPA regimen is essential since the rapid improvements in health-care facilities and public awareness are expected to increase the rates of thrombolysis in Asia. © 2011 The Authors.

Acute Hepatitis Associated with The Use of Herbal Tea (Fennel and Cumin

Directory of Open Access Journals (Sweden)

Suat Zengin

2014-03-01

Full Text Available Herbal remedies have become increasingly popular throughout the globe as a result of disappointment with conventional medicines. The public often regards them as harmless. However, some of these products or their metabolites can cause adverse effects such as liver damage. In this study, two patients who developed acute hepatitis due to consuming herbal tea are presented. Twenty-six and thirty-year-old two women were admitted to our department with symptoms of nausea, vomiting, anorexia and weakness. Serum alanine aminotransferase and aspartate aminotransferase levels were increased; all serological tests for viral hepatitis and autoimmune disorders were negative. They had consumed an herbal tea containing fennel and cumin to increase lactation everyday for three-four weeks. Discontinuation of the herbal tea resulted in normalization of liver enzymes four-five weeks later. To the best of our knowledge, this is the first report of hepatitis possibly related to use of an herbal tea containing fennel and cumin. This study suggests that herbal tea containing fennel and cumin can cause hepatotoxicity, which could be clinically confused with other causes of acute hepatitis. Clinicians may face with a case of acute hepatitis that is not readily diagnosed, and should question patients about herbal remedy use.

Gravity-dependent nystagmus and inner-ear dysfunction suggest anterior and posterior inferior cerebellar artery infarct.

Cerebellar lesions may present with gravity-dependent nystagmus, where the direction and velocity of the drifts change with alterations in head position. Two patients had acute onset of hearing loss, vertigo, oscillopsia, nausea, and vomiting. Examination revealed gravity-dependent nystagmus, unilateral hypoactive vestibulo-ocular reflex (VOR), and hearing loss ipsilateral to the VOR hypofunction. Traditionally, the hypoactive VOR and hearing loss suggest inner-ear dysfunction. Vertigo, nausea, vomiting, and nystagmus may suggest peripheral or central vestibulopathy. The gravity-dependent modulation of nystagmus, however, localizes to the posterior cerebellar vermis. Magnetic resonance imaging in our patients revealed acute cerebellar infarct affecting posterior cerebellar vermis, in the vascular distribution of the posterior inferior cerebellar artery (PICA). This lesion explains the gravity-dependent nystagmus, nausea, and vomiting. Acute onset of unilateral hearing loss and VOR hypofunction could be the manifestation of inner-ear ischemic injury secondary to the anterior inferior cerebellar artery (AICA) compromise. In cases of combined AICA and PICA infarction, the symptoms of peripheral vestibulopathy might masquerade the central vestibular syndrome and harbor a cerebellar stroke. However, the gravity-dependent nystagmus allows prompt identification of acute cerebellar infarct. Copyright © 2014 National Stroke Association. Published by Elsevier Inc. All rights reserved.

Traumatic and nontraumatic rhabdomyolysis can lead to acute renal failure (ARF), and acute alcohol intoxication can lead to multiple abnormalities of the renal tubules. We examined the effect of acute alcohol intoxication in a rat model of rhabdomyolysis and ARF. Intravenous injections of 5 g/kg ethanol were given to rats over 3 h, followed by glycerol-induced rhabdomyolysis. Biochemical parameters, including blood urea nitrogen (BUN), creatinine (Cre), glutamic oxaloacetic transaminase (GOT), glutamic pyruvic transaminase (GPT), and creatine phosphokinase (CPK), were measured before and after induction of rhabdomyolysis. Renal tissue injury score, renal tubular cell expression of E-cadherin, nuclear factor-κB (NF-κB), and inducible nitric oxide synthase (iNOS) were determined. Relative to rats in the vehicle group, rats in the glycerol-induced rhabdomyolysis group had significantly increased serum levels of BUN, Cre, GOT, GPT, and CPK, elevated renal tissue injury scores, increased expression of NF-κB and iNOS, and decreased expression of E-cadherin. Ethanol exacerbated all of these pathological responses. Our results suggest that acute alcohol intoxication exacerbates rhabdomyolysis-induced ARF through its pro-oxidant and inflammatory effects.

2017-06-01

Although intestinal parasitic infections rarely cause acute appendicitis, they are common public health problems in undeveloped and developing countries. Parasitic infections should be kept in mind in patients clinically suspected of having acute appendicitis, and treatment procedures should be adopted according to the etiology. Herein we presented the cases of four patients with clinical findings of acute appendicitis. Patients were clinically suspected of having acute appendicitis, and Enterobius vermicularis was detected in the pathological examinations of specimens. Pinworm infections are common parasitic infections that may mimic appendicitis. The pathology of the four cases was noted when the file of 186 patients aged between 4 and 72 years who underwent surgery for acute appendicitis in my hospital was retrospectively reviewed. When the appendectomy specimen was examined histopathologically it was understood that acute appendicitis was caused by Enterobius vermicularis parasite. In Enterobius infections, performing systemic therapy for patients and their family members is sufficient. To prevent unnecessary appendectomy, this type of infection should be made to ask in the history and clinical findings of patients.

Misleading signs in acute vertigo.

Lance, Sean; Mossman, Stuart Scott

2018-04-01

The acute vestibular syndrome is common and usually has a benign cause. Sometimes, however, even experienced neurologists can find it difficult to determine the cause clinically. Furthermore, neuroimaging is known to be insensitive.We describe two cases of acute vestibular syndrome where conflicting clinical findings contributed to a delay in making the correct diagnosis. The first patient with symptomatic vertigo had signs consistent with horizontal benign paroxysmal positional vertigo but also had an abnormal horizontal head impulse test, superficially suggesting acute vestibular neuritis but later accounted for by the finding of a vestibular schwannoma (acoustic neuroma). The second patient also had an abnormal horizontal head impulse test, with skew deviation suggesting stroke as the cause. However, later assessment identified that a long-standing fourth nerve palsy was the true cause for her apparent skew. We discuss potential errors that can arise when assessing such patients and highlight ways to avoid them. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

The use of cryotherapy in the management of acute soft tissue injury is largely based on anecdotal evidence. Preliminary evidence suggests that intermittent cryotherapy applications are most effective at reducing tissue temperature to optimal therapeutic levels. However, its efficacy in treating injured human subjects is not yet known. To compare the efficacy of an intermittent cryotherapy treatment protocol with a standard cryotherapy treatment protocol in the management of acute ankle sprains. Sportsmen (n = 44) and members of the general public (n = 45) with mild/moderate acute ankle sprains. Subjects were randomly allocated, under strictly controlled double blind conditions, to one of two treatment groups: standard ice application (n = 46) or intermittent ice application (n = 43). The mode of cryotherapy was standardised across groups and consisted of melting iced water (0 degrees C) in a standardised pack. Function, pain, and swelling were recorded at baseline and one, two, three, four, and six weeks after injury. Subjects treated with the intermittent protocol had significantly (p<0.05) less ankle pain on activity than those using a standard 20 minute protocol; however, one week after ankle injury, there were no significant differences between groups in terms of function, swelling, or pain at rest. Intermittent applications may enhance the therapeutic effect of ice in pain relief after acute soft tissue injury.

Diffusion-weighted imaging (DWI) has become a reference MRI technique for the evaluation of neurological disorders. Few publications have investigated the application of DWI for inflammatory demyelinating lesions. The purpose of the study was to describe diffusion-weighted imaging characteristics of acute, spinal demyelinating lesions. Six consecutive patients (two males, four females; aged 28-64 years) with acute spinal cord demyelinating lesions were studied in a prospective case series design from June 2009 to October 2010. We performed magnetic resonance imaging studies from 2 to 14 days from symptom onset on the patients with relapsing remitting multiple sclerosis (n = 3) or clinically isolated syndrome (n = 3). Main outcome measures were diffusion-weighted imaging and apparent diffusion coefficient pattern (ADC) of acute spinal cord demyelinating lesions. All spinal lesions showed a restricted diffusion pattern (DWI+/ADC-) with a 24% median ADC signal decrease. A good correlation between clinical presentation and lesion site was observed. Acute demyelinating spinal cord lesions show a uniform restricted diffusion pattern. Clinicians and neuro-radiologists should be aware that this pattern is not necessarily confirmatory for an ischaemic aetiology. (orig.)

Kaballo, Mohammed A; Elsayed, Mohamed E; Stack, Austin G

2017-08-01

Acute kidney injury (AKI) is considered to be a major public health problem around the globe, and it is associated with major adverse clinical outcomes and significant health care costs. There is growing evidence suggesting that AKI is associated with the subsequent development of chronic kidney disease (CKD). While recovery of kidney function occurs in the majority of patients surviving an AKI episode, a large number of patients do not recover completely. Similarly, CKD is a well-known risk factor for the development of AKI. Recent studies suggest that both AKI and CKD are not separate disease entities but are in fact components of a far more closely interconnected disease continuum. However, the true nature of this relationship is complex and poorly understood. This review explores potential relationships between AKI and CKD, and seeks to uncover a number of "missing links" in this tentative emerging relationship.

2011-03-01

Full Text Available Introduction: The association of acute viral hepatitis and acute pancreatitis is well described. This study was conducted to find out the frequency of pancreatic involvement in acute viral hepatitis in the Nepalese population. Methods: Consecutive patients of acute viral hepatitis presenting with severe abdominal pain between January 2005 and April 2010 were studied. Patients with history of significant alcohol consumption and gall stones were excluded. Acute viral hepatitis was diagnosed by clinical examination, liver function test, ultrasound examination and confirmed by viral serology. Pancreatitis was diagnosed by clinical presentation, biochemistry, ultrasound examination and CT scan. Results: Severe abdominal pain was present in 38 of 382 serologically-confirmed acute viral hepatitis patients. Twenty five patients were diagnosed to have acute pancreatitis. The pancreatitis was mild in 14 and severe in 11 patients. The etiology of pancreatitis was hepatitis E virus in 18 and hepatitis A virus in 7 patients. Two patients died of complications secondary to shock. The remaining patients recovered from both pancreatitis and hepatitis on conservative treatment. Conclusions: Acute pancreatitis occurred in 6.5 % of patients with acute viral hepatitis. Cholelithiasis and gastric ulcers are the other causes of severe abdominal pain. The majority of the patients recover with conservative management. Keywords: acute viral hepatitis, acute pancreatitis, pain abdomen, hepatitis E, hepatitis A, endemic zone

Acute muscular weakness in children

Directory of Open Access Journals (Sweden)

Ricardo Pablo Javier Erazo Torricelli

Full Text Available ABSTRACT Acute muscle weakness in children is a pediatric emergency. During the diagnostic approach, it is crucial to obtain a detailed case history, including: onset of weakness, history of associated febrile states, ingestion of toxic substances/toxins, immunizations, and family history. Neurological examination must be meticulous as well. In this review, we describe the most common diseases related to acute muscle weakness, grouped into the site of origin (from the upper motor neuron to the motor unit. Early detection of hyperCKemia may lead to a myositis diagnosis, and hypokalemia points to the diagnosis of periodic paralysis. Ophthalmoparesis, ptosis and bulbar signs are suggestive of myasthenia gravis or botulism. Distal weakness and hyporeflexia are clinical features of Guillain-Barré syndrome, the most frequent cause of acute muscle weakness. If all studies are normal, a psychogenic cause should be considered. Finding the etiology of acute muscle weakness is essential to execute treatment in a timely manner, improving the prognosis of affected children.

Over an 18-month period, high resolution ultrasound was used to assess 220 patients with doubtful clinical diagnosis of acute appendicitis. The ultrasonographic findings were correlated with the surgical results and the pathological results in 115 cases, and with clinical follow-up in the rest. This technique has been found to be effective in the diagnosis of acute appendicitis, with a sensitivity of 90.4%, and similar specificity and reliability (90.2%). The positive predictive value of the test was 89% and the negative predictive value, 91%. The ultrasonographic criteria applied for the diagnosis of acute appendicitis was the detection of an understood appendix measuring over 6 mm. All cases with perforation were correctly diagnosed as acute appendicitis. The observation of an accumulation of fluid pooled in DIF in patients with ultrasonographic findings suggestive of appendicitis points to a diagnosis of perforation or complicated (gangrenous) appendicitis. A relationship between complicated appendicitis and the detection of appendicoliths within the enlarged appendix was also observed. The results obtained demonstrate that high resolution ultrasound is indicated in the diagnosis of acute appendicitis in all cases in which the clinical findings are doubtful

Ninety-one patients with chest pain suggestive of acute myocardial infarction were studied by static technetium /sup 99m/Tc stannous pyrophosphate scintigraphy and dynamic sodium pertechnetate /sup 99m/Tc cardioangiography. Twenty-three of 26 patients (88%) with acute transmural infarcts and 12 of 17 patients (71%) with nontransmural infarcts had abnormal static studies. In 45 patients with negative scintigrams, ECG or serum enzyme changes consistent with acute infarction failed to develop. Three false-positive static studies (6%) were recorded. Twenty of 43 (47%) patients with acute infarction had hemodynamic or structural abnormalities identified by cardioangiography. The dynamic study also proved helpful in localizing the site of infarction and in ruling out certain causes of false-positive static scintigrams

Full Text Available Introduction Among the organs of internal secretion pancreas has a special place thanks to active exocrine function and a wide range of physiological actions of produced hormones. Violations of endocrine pancreas arises in 6.5-38 % of patients with acute pancreatitis. However, there is still no clear understanding of the pathogenetic mechanisms of hormonal dysfunction of the pancreas in acute pancreatitis, there is no uniform algorithms for its correction. Aim of the research was to study the endocrine function of pancreas in acute pancreatitis. To define the role of endocrine pancreatic function in the etiology and pathogenesis of the acute pancreatitis. To assess the prospects of the use of pancreatic hormones in the treatment and predicting the outcomes of acute pancreatitis. Materials and methods of the research Survey of publications in specialized periodical medical journals, PubMed sources developed by the National Center for Biotechnology Information. Search in PubMed was carried out in the following databases: MEDLINE, Pre MEDLINE. Results of the research. In a significant proportion of patients who recovered from acute pancreatitis, exocrine and endocrine functional impairments were found. This finding was not detected only in patients after severe acute pancreatitis. Routine evaluation of pancreatic function after acute pancreatitis should be considered. The comparative analysis of the synthetic analogues (somatostatin, calcitonin, leu-enkefalin-dalargin influence on the glucose metabolism of rats in acute pancreatitis of was made. Physiological reaction of beta-cells is preserved in infusion of somatostatin. However, infusion of calcitonin results in the distortion of counterregulatory action of insulin and glucagon. It was detected that pancreatic renin-angiotensin system is markedly activated in the experimental rat models of chronic hypoxia and acute pancreatitis.

Intravenous thrombolysis (IVT) with alteplase (tissue plasminogen activator) is the standard pharmacological treatment in acute ischemic stroke (AIS), reducing disability in patients. To report the results a thrombolysis protocol during four years in a regional public hospital. Data from 106 consecutive patients aged 68 ± 13 years (57% men) who were treated with IVT, from May 2012 until April 2016, was analyzed. The median door-to-needle time was 80 minutes (interquartile range = 57-113). The median National Institute of Health Stroke Scale (NIHSS) scores on admission and at discharge were was 11.5 and 5 points respectively. At discharge, 27% of hospitalized patients had a favorable outcome (n = 99), defined as having 0 to 1 points in the modified Rankin scale. Symptomatic intracerebral hemorrhage and mortality rates were 5.7 and 13.1%, respectively. The thrombolysis rate rose from 0.7% in 2012 to 6% in 2016. The implementation of 24/7 neurology shifts in the Emergency Department allowed us to increase the amount and quality of IVT in our hospital, as measured by the rate of thrombolysis and by process indicators such as door-to-needle time.

2014-07-01

We report a case of 30 year old alcoholic male admitted with vomiting, drowsiness, limb weakness and fasciculations after alleged history of consumption of 30 ml of chlorpyriphos insecticide. He had low serum cholinesterase levels. With standard treatment for organophosphorus poisoning (OPP), he improved gradually until day 5, when he developed neck and limb weakness and respiratory distress. This intermediate syndrome was treated with oximes, atropine and artificial ventilation. During treatment, his ECG showed fresh changes of ST elevation. High CPK & CPK-MB levels, septal hypokinesia on 2D echo suggested acute coronary syndrome. Coronary angiography was postponed due to his bedridden and obtunded status. The patient finally recovered fully by day 15 and was discharged. Acute coronary syndrome is a rare occurrence in OP poisoning. The present case thus emphasises the need for careful electrocardiographic and enzymatic monitoring of all patients of organophosphorus poisoning to prevent potential cardiac complication which can prove fatal.

Role of autophagy in development and progression of acute pancreatitis

Directory of Open Access Journals (Sweden)

YANG Shuli

2014-08-01

Full Text Available Acute pancreatitis is considered an autodigestive disorder in which inappropriate activation of trypsinogen to trypsin within pancreatic acinar cells leads to the development of pancreatitis. Autophagy is an evolutionarily preserved degradation process of cytoplasmic cellular constituents, and it is one of the early pathological processes in acute pancreatitis. Autophagic flux is impaired in acute pancreatitis, which mediates the key pathologic responses of this disease. Impaired autophagy, dysfunction of lysosomes, and dysregulation of autophagy suggest a disorder of the endolysosomal pathway in acute pancreatitis. The role of autophagy in acute pancreatitis is discussed from the aspects of autophagic process, autophagy and activation of trypsinogen, impaired autophagy and acute pancreatitis, and defective autophagy promoting inflammation.

Objective. With the increasing societal awareness of the prevalence and impact of acute pain, there is a need to develop an acute pain classification system that both reflects contemporary mechanistic insights and helps guide future research and treatment. Existing classifications of acute pain conditions are limiting, with a predominant focus on the sensory experience (e.g., pain intensity) and pharmacologic consumption. Consequently, there is a need to more broadly characterize and classify the multidimensional experience of acute pain. Setting. Consensus report following expert panel involving the Analgesic, Anesthetic, and Addiction Clinical Trial Translations, Innovations, Opportunities, and Networks (ACTTION), American Pain Society (APS), and American Academy of Pain Medicine (AAPM). Methods. As a complement to a taxonomy recently developed for chronic pain, the ACTTION public-private partnership with the US Food and Drug Administration, the APS, and the AAPM convened a consensus meeting of experts to develop an acute pain taxonomy using prevailing evidence. Key issues pertaining to the distinct nature of acute pain are presented followed by the agreed-upon taxonomy. The ACTTION-APS-AAPM Acute Pain Taxonomy will include the following dimensions: 1) core criteria, 2) common features, 3) modulating factors, 4) impact/functional consequences, and 5) putative pathophysiologic pain mechanisms. Future efforts will consist of working groups utilizing this taxonomy to develop diagnostic criteria for a comprehensive set of acute pain conditions. Perspective. The ACTTION-APS-AAPM Acute Pain Taxonomy (AAAPT) is a multidimensional acute pain classification system designed to classify acute pain along the following dimensions: 1) core criteria, 2) common features, 3) modulating factors, 4) impact/functional consequences, and 5) putative pathophysiologic pain mechanisms. Conclusions. Significant numbers of patients still suffer from significant acute pain

With the increasing societal awareness of the prevalence and impact of acute pain, there is a need to develop an acute pain classification system that both reflects contemporary mechanistic insights and helps guide future research and treatment. Existing classifications of acute pain conditions are limiting, with a predominant focus on the sensory experience (eg, pain intensity) and pharmacologic consumption. Consequently, there is a need to more broadly characterize and classify the multidimensional experience of acute pain. Consensus report following expert panel involving the Analgesic, Anesthetic, and Addiction Clinical Trial Translations, Innovations, Opportunities, and Networks (ACTTION), American Pain Society (APS), and American Academy of Pain Medicine (AAPM). As a complement to a taxonomy recently developed for chronic pain, the ACTTION public-private partnership with the US Food and Drug Administration, the APS, and the AAPM convened a consensus meeting of experts to develop an acute pain taxonomy using prevailing evidence. Key issues pertaining to the distinct nature of acute pain are presented followed by the agreed-upon taxonomy. The ACTTION-APS-AAPM Acute Pain Taxonomy will include the following dimensions: 1) core criteria, 2) common features, 3) modulating factors, 4) impact/functional consequences, and 5) putative pathophysiologic pain mechanisms. Future efforts will consist of working groups utilizing this taxonomy to develop diagnostic criteria for a comprehensive set of acute pain conditions. The ACTTION-APS-AAPM Acute Pain Taxonomy (AAAPT) is a multidimensional acute pain classification system designed to classify acute pain along the following dimensions: 1) core criteria, 2) common features, 3) modulating factors, 4) impact/functional consequences, and 5) putative pathophysiologic pain mechanisms. Significant numbers of patients still suffer from significant acute pain, despite the advent of modern multimodal analgesic strategies

Perinatal pathology: practice suggestions for limited-resource settings.

Science.gov (United States)

Roberts, Drucilla J

2013-06-01

The practice of perinatal pathology in much of the world suffers, as do all subspecialties of anatomic pathology, from inadequate resources (equipment, consumables, and both professional and technical personnel), from lack of education (not only of the pathologist but also of the clinicians responsible for sending the specimens, and the technicians processing the specimens), and from lack of appropriate government sector support. Perinatal pathology has significant public health-related utility and should be championing its service by providing maternal and fetal/infant mortality and morbidity data to governmental health ministries. It is with this pathologic data that informed decisions can be made on health-related courses of action and allocation of resources. These perinatal pathology data are needed to develop appropriate public health initiatives, specifically toward achieving the Millennium Developmental Goals as the best way to effectively decrease infant and maternal deaths and to determine causes of perinatal mortality and morbidity. The following overview will focus on the utility of perinatal pathology specifically as related to its public health function and will suggest methods to improve its service in resource-poor settings. This article is offered not as a critique of the current practice that most pathologists find themselves working in globally, but to provide suggestions for improving perinatal pathology services, which could be implemented with the limited available resources and manpower most pathology departments currently have. In addition, we offer suggestions for graded improvements ("ramping up") over time.

Many studies have shown an association between air quality and acute deaths, and such associations are widely interpreted as causal. Several factors call causation and even association into question, for example multiple testing and multiple modeling, publication bias and confirmation bias. Many published studies are difficult or impossible to reproduce because of lack of access to confidential data sources. Here we make publically available a dataset containing daily air quality levels, PM 2.5 and ozone, daily temperature levels, minimum and maximum and daily maximum relative humidity levels for the eight most populous California air basins, thirteen years, >2M deaths, over 37,000 exposure days. The data are analyzed using standard time series analysis, and a sensitivity analysis is computed varying model parameters, locations and years. Our analysis finds little evidence for association between air quality and acute deaths. These results are consistent with those for the widely cited NMMAPS dataset when the latter are restricted to California. The daily death variability was mostly explained by time of year or weather variables; Neither PM 2.5 nor ozone added appreciably to the prediction of daily deaths. These results call into question the widespread belief that association between air quality and acute deaths is causal/near-universal. Copyright © 2017 Elsevier Inc. All rights reserved.

Krewski, Daniel; Bakshi, Kulbir; Garrett, Roger; Falke, Ernest; Rusch, George; Gaylor, David

2004-04-01

Hazardous substances can be released into the atmosphere due to industrial and transportation accidents, fires, tornadoes, earthquakes, and terrorists, thereby exposing workers and the nearby public to potential adverse health effects. Various enforceable guidelines have been set by regulatory agencies for worker and ambient air quality. However, these exposure levels generally are not applicable to rare lifetime acute exposures, which possibly could occur at high concentrations. Acute exposure guideline levels (AEGLs) provide estimates of concentrations for airborne exposures for an array of short durations that possibly could cause mild (AEGL-1), severe, irreversible, potentially disabling adverse health effects (AEGL-2), or life threatening effects (AEGL-3). These levels can be useful for emergency responders and planners in reducing or eliminating potential risks to the public. Procedures and methodologies for deriving AEGLs are reviewed in this paper that have been developed in the United States, with direct input from international representatives of OECD member-countries, by the National Advisory Committee for Acute Exposure Guidelines for Hazardous Substances and reviewed by the National Research Council. Techniques are discussed for the extrapolation of effects across different exposure durations. AEGLs provide a viable approach for assisting in the prevention, planning, and response to acute airborne exposures to toxic agents.

Western studies have suggested that emotional stress and distress impacted on the morbidity and mortality in people following acute coronary events. Symptoms of anxiety and depression have been associated with re-infarction and death, prolonged recovery and disability and depression may precipitate the client's low self-esteem. This study examined perceived anxiety, depression and self-esteem of Hong Kong Chinese clients diagnosed with acute coronary syndrome (ACS) over a 6-month period following hospital admission. To examine: A prospective, repeated measures design with measures taken on two occasions over a 6-month period; (1) within the 1st week of hospital admission following the onset of ACS and (2) at 6 months follow up. Convenient sample of 182 voluntary consented clients admitted with ACS to a major public hospital in Hong Kong who could communicate in Chinese, complete questionnaires, cognitive intact, and were haemodynamically stable and free from acute chest pain at the time of interview. Baseline data were obtained within 1 week after hospital admission. The follow-up data was collected 6 months after hospital discharge. The Chinese version of the Hospital Anxiety and Depression Scale (HADS), State Self-esteem Scale (SSES), and Rosenberg's Self-Esteem Scale (RSES) were used to assess anxiety and depression, state self-esteem, and trait self-esteem, respectively. Findings suggested gender differences in clients' perception in anxiety, depression and self-esteem. Improvements in clients' perception of these variables were evident over the 6-month period following their acute coronary events. The study confirmed the western notion that psychosocial problems are common among coronary clients and this also applies to Hong Kong Chinese diagnosed with ACS. Further studies to explore effective interventions to address these psychosocial issues are recommended.

Identification of acute self-limited hepatitis B among patients presenting with hepatitis B virus-related acute hepatitis: a hospital-based epidemiological and clinical study.

Han, Y-N

2009-01-01

This study aimed to identify acute self-limited hepatitis B (ASL-HB) among patients presenting with hepatitis B virus (HBV)-related acute hepatitis. Data were available for 220 patients diagnosed with HBV-related acute hepatitis, of whom 164 had acute hepatitis B (AHB). Of these, 160 were confirmed as ASL-HB: three (1.9%) evolved to chronic hepatitis B and one (0.6%) developed fulminant hepatitis and died. Comparisons were also made between AHB and acute infections with hepatitis A (HA) and hepatitis E (HE) viruses. During the study period, the number of patients with AHB exceeded the sum of those with acute HA and acute HE infections. There was no distinct seasonal peak for AHB infection, whereas both acute HA and acute HE infections occurred more frequently in the spring. Clinical symptoms and physical signs were similar for all three types of hepatitis, but significant differences were seen in some biochemical parameters. In conclusion, this study suggests that symptomatic AHB is not rare in China but it seldom evolves to chronic hepatitis B.

Jin, Faguang; Li, Congcong

2017-06-01

Drowning is a crucial public safety problem and is the third leading cause of accidental fatality, claiming ~372,000 lives annually, worldwide. In near-drowning patients, acute lung injury (ALI) or acute respiratory distress syndrome (ARDS) is one of the most common complications. Approximately 1/3 of near-drowning patients fulfill the criteria for ALI or ARDS. In the present article, the current literature of near-drowning, pathophysiologic changes and the molecular mechanisms of seawater-drowning-induced ALI and ARDS was reviewed. Seawater is three times more hyperosmolar than plasma, and following inhalation of seawater the hyperosmotic seawater may cause serious injury in the lung and alveoli. The perturbing effects of seawater may be primarily categorized into insufficiency of pulmonary surfactant, blood-air barrier disruption, formation of pulmonary edema, inflammation, oxidative stress, autophagy, apoptosis and various other hypertonic stimulation. Potential treatments for seawater-induced ALI/ARDS were also presented, in addition to suggestions for further studies. A total of nine therapeutic strategies had been tested and all had focused on modulating the over-activated immunoreactions. In conclusion, seawater drowning is a complex injury process and the exact mechanisms and potential treatments require further exploration.

This study performed an acute oral toxicity test of 59 compounds in silkworms. These compounds are listed in OECD guidelines as standard substances for a cytotoxicity test, and median lethal dose (LD(50)) werecalculated for each compound. Acute oral LD(50) values in mammals are listed in OECD guidelines and acute oral LD(50) values in silkworms were determined in this study. R(2) for the correlation between LD(50) values in mammals and LD(50) values in silkworms was 0.66. In addition, the acute oral toxicity test in silkworms was performed by two different facilities, and test results from the facilities were highly reproducible. These findings suggest that an acute oral toxicity test in silkworms is a useful way to evaluate the toxicity of compounds in mammals.

To evaluate changes in glomerular filtration rate in acute gastroenteritis. The correlation between two clinical diagnostic scales and glomerular filtration rate has been investigated in 113 children with acute gastroenteritis in a paediatric emergency setting. A significant reduction of GFR was found in 10% children less than, and 5% children higher than, 2 years of age with acute gastroenteritis. The differences observed as for risk of renal hypoperfusion suggests to consider the age of children as an important determinant to consider the dehydration status in acute gastroenteritis. ©2013 Foundation Acta Paediatrica.

1979-01-01

Vindesine was administered to 18 patients with acute leukemia who had failed conventional chemotherapy. Each course of therapy consisted of an iv bolus infusion at a dose of 1-2 mg/m2 given daily x 5-10 days. Of 13 patients with acute lymphoblastic leukemia, two had partial remissions which lasted 2 and 3 months and five had minor responses. One of three patients with acute nonlymphoblastic leukemia and one of two patients with blastic crisis of chronic myelogenous leukemia each had a minor response. The data suggest that vindesine has activity in the treatment of acute leukemia.

Toxicity levels to humans during acute exposure to hydrogen fluoride - An update

Halton, D.M.

1995-09-01

In March 1993, the Atomic Energy Control Board (AECB) commissioned and update of a 1984 review on the acute toxicity of hydrogen fluoride (HF). The study places particular emphasis on the effects of inhalation of gaseous HF and is divided into two main parts: a literature review and a lethal concentration (LC) estimation. The literature review summarizes data under four categories: animal studies, controlled human studies, community exposure, and industrial exposure. Data in these areas were critically reviewed for their relevance to lethal concentrations at LC LO , LC 10 and LC 50 levels that were derived in the 1984 report. In the last ten years, only one relevant animal study has been published. No new controlled human studies were found but a community exposure incident was reported. There were three new industrial/accidental exposures reported since 1984. Evaluation of new data does not change the lethal concentration estimates made in the 1984 report, but does indicate the absence of appropriate models to estimate the lethality of irritant and corrosive gases. In the last 10 years, much literature on the evaluation of major hazards has been published and suggests that such assessments are of growing political, economic and social importance. Numerous articles have been published on the acute toxicity of HF from skin contact and chronic toxicity from repeated airborne exposure. These publications offer important insights into the nature of HF toxicity. Several avenues of investigative research are suggested. (author). 55 refs., 4 tabs

Corticostriatal Regulation of Acute Pain

Directory of Open Access Journals (Sweden)

Erik Martinez

2017-05-01

Full Text Available The mechanisms for acute pain regulation in the brain are not well understood. The prefrontal cortex (PFC provides top-down control of emotional processes, and it projects to the nucleus accumbens (NAc. This corticostriatal projection forms an important regulatory pathway within the brain’s reward system. Recently, this projection has been suggested to control both sensory and affective phenotypes specifically associated with chronic pain. As this projection is also known to play a role in the transition from acute to chronic pain, we hypothesized that this corticostriatal circuit can also exert a modulatory function in the acute pain state. Here, we used optogenetics to specifically target the projection from the PFC to the NAc. We tested sensory pain behaviors with Hargreaves’ test and mechanical allodynia, and aversive pain behaviors with conditioned place preference (CPP test. We found that the activation of this corticostriatal circuit gave rise to bilateral relief from peripheral nociceptive inputs. Activation of this circuit also provided important control for the aversive response to transient noxious stimulations. Hence, our results support a novel role for corticostriatal circuitry in acute pain regulation.

The acute toxicity of cannabinoids is said to be low and there is little public awareness of the potentially hazardous cardiovascular effects of cannabis, e.g. marked increase in heart rate or supine blood pressure. We describe the cases of two young, putative healthy men who died unexpectedly under the acute influence of cannabinoids. To our knowledge, these are the first cases of suspected fatal cannabis intoxications where full postmortem investigations, including autopsy, toxicological, histological, immunohistochemical and genetical examinations, were carried out. The results of these examinations are presented. After exclusion of other causes of death we assume that the young men experienced fatal cardiovascular complications evoked by smoking cannabis.

Full Text Available Acute acalculous cholecystitis is a rare complication in the treatment of acute myeloblastic leukemia. Diagnosis of acute acalculous cholecystitis remains difficult during neutropenic period. We present two acute myeloblastic leukemia patients that developed acute acalculous cholecystitis during chemotherapy-induced neutropenia. They suffered from fever, vomiting and acute pain in the epigastrium. Ultrasound demonstrated an acalculous gallbladder. Surgical management was required in one patient and conservative treatment was attempted in the other patient. None treatment measures were effective and two patients died. Acute acalculous cholecystitis is a serious complication in neutropenic patients. Earlier diagnosis could have expedited the management of these patients.

Donahue, Christopher B; Kushner, Matt G; Thuras, Paul D; Murphy, Tom G; Van Demark, Joani B; Adson, David E

2009-04-01

Clinical practice and open-label studies suggest that quetiapine (an atypical anti-psychotic) might improve symptoms for individuals with social anxiety disorder (SAD). The purpose of this study was to provide a rigorous test of the acute impact of a single dose of quetiapine (25mg) on SAD symptoms. Individuals with SAD (N=20) were exposed to a 4-min virtual reality (VR) public speaking challenge after having received quetiapine or placebo (double-blind) 1h earlier. A parallel VR challenge occurred 1 week later using a counter-balanced cross-over (within subject) design for the medication-placebo order between the two sessions. There was no significant drug effect for quetiapine on the primary outcome measures. However, quetiapine was associated with significantly elevated heart rate and sleepiness compared with placebo. Study findings suggest that a single dose of 25mg quetiapine is not effective in alleviating SAD symptoms in individuals with fears of public speaking.

Differentiating Acute Otitis Media and Acute Mastoiditis in Hospitalized Children.

Science.gov (United States)

Laulajainen-Hongisto, Anu; Aarnisalo, Antti A; Jero, Jussi

2016-10-01

Acute otitis media is a common infection in children. Most acute otitis media episodes can be treated at an outpatient setting with antimicrobials, or only expectant observation. Hospital treatment with parenteral medication, and myringotomy or tympanostomy, may be needed to treat those with severe, prolonged symptoms, or with complications. The most common intratemporal complication of acute otitis media is acute mastoiditis. If a child with acute mastoiditis does not respond to this treatment, or if complications develop, further examinations and other surgical procedures, including mastoidectomy, are considered. Since the treatment of complicated acute otitis media and complicated acute mastoiditis differs, it is important to differentiate these two conditions. This article focuses on the differential diagnostics of acute otitis media and acute mastoiditis in children.

Acute Moderate Exercise Improves Mnemonic Discrimination in Young Adults

Suwabe, Kazuya; Hyodo, Kazuki; Byun, Kyeongho; Ochi, Genta; Yassa, Michael A.; Soya, Hideaki

Increasing evidence suggests that regular moderate exercise increases neurogenesis in the dentate gyrus (DG) of the hippocampus and improves memory functions in both humans and animals. The DG is known to play a role in pattern separation, which is the ability to discriminate among similar experiences, a fundamental component of episodic memory. While long-term voluntary exercise improves pattern separation, there is little evidence of alterations in DG function after an acute exercise session. Our previous studies showing acute moderate exercise-enhanced DG activation in rats, and acute moderate exercise-enhanced prefrontal activation and executive function in humans, led us to postulate that acute moderate exercise may also activate the hippocampus, including more specifically the DG, thus improving pattern separation. We thus investigated the effects of a 10-min moderate exercise (50% V̇O2peak) session, the recommended intensity for health promotion, on mnemonic discrimination (a behavioral index of pattern separation) in young adults. An acute bout of moderate exercise improved mnemonic discrimination performance in high similarity lures. These results support our hypothesis that acute moderate exercise improves DG-mediated pattern separation in humans, proposing a useful human acute-exercise model for analyzing the neuronal substrate underlying acute and regular exercise-enhanced episodic memory based on the hippocampus.

An hypnotic suggestion: review of hypnosis for clinical emergency care.

Science.gov (United States)

Iserson, Kenneth V

2014-04-01

Hypnosis has been used in medicine for nearly 250 years. Yet, emergency clinicians rarely use it in emergency departments or prehospital settings. This review describes hypnosis, its historical use in medicine, several neurophysiologic studies of the procedure, its uses and potential uses in emergency care, and a simple technique for inducing hypnosis. It also discusses reasons why the technique has not been widely adopted, and suggests methods of increasing its use in emergency care, including some potential research areas. A limited number of clinical studies and case reports suggest that hypnosis may be effective in a wide variety of conditions applicable to emergency medical care. These include providing analgesia for existing pain (e.g., fractures, burns, and lacerations), providing analgesia and sedation for painful procedures (e.g., needle sticks, laceration repair, and fracture and joint reductions), reducing acute anxiety, increasing children's cooperation for procedures, facilitating the diagnosis and treatment of acute psychiatric conditions, and providing analgesia and anxiolysis for obstetric/gynecologic problems. Although it is safe, fast, and cost-effective, emergency clinicians rarely use hypnosis. This is due, in part, to the myths surrounding hypnosis and its association with alternative-complementary medicine. Genuine barriers to its increased clinical use include a lack of assured effectiveness and a lack of training and training requirements. Based on the results of further research, hypnosis could become a powerful and safe nonpharmacologic addition to the emergency clinician's armamentarium, with the potential to enhance patient care in emergency medicine, prehospital care, and remote medical settings.

This Delphi study provides consensus related to many aspects of acute diverticulitis and identifies other areas in need of research. To generate an international, expert-based, consensus statement to address controversies in the management of acute diverticulitis. This study was conducted using the Delphi technique from April 3 through October 21, 2014. A survey website was used and a panel of acute diverticulitis experts was formed via the snowball method. The top 5 acute diverticulitis experts in 5 international geographic regions were identified based on their number of publications related to acute diverticulitis. The Delphi study used 3 rounds of questions, after which the consensus statement was collated. A consensus statement related to the management of acute diverticulitis. Twenty items were selected for inclusion in the consensus statement following 3 rounds of questioning. A clear definition of uncomplicated and complicated diverticulitis is provided. In uncomplicated diverticulitis, consensus was reached regarding appropriate laboratory and radiological evaluation of patients as well as nonsurgical, surgical, and follow-up strategies. A number of important topics, including antibiotic treatment, failed to reach consensus. In addition, consensus was reached regarding many nonsurgical and surgical treatment strategies in complicated diverticulitis. Controversy continues internationally regarding the management of acute diverticulitis. This study demonstrates that there is more nonconsensus among experts than consensus regarding most issues, even in the same region. It also provides insight into the status quo regarding the treatment of acute diverticulitis and provides important direction for future research.

In this study, we argue that contemporary nursing care has been overtaken by new public management strategies aimed at curtailing budgets in the public hospital sector in Australia. Drawing on qualitative interviews with 15 nurses from one public acute hospital with supporting documentary evidence, we demonstrate what happens to nursing work when management imposes rounding as a risk reduction strategy. In the case study outlined rounding was introduced across all wards in response to missed care, which in turn arose as a result of work intensification produced by efficiency, productivity, effectiveness and accountability demands. Rounding is a commercially sponsored practice consistent with new public management. Our study illustrates the impact that new public management strategies such as rounding have on how nurses work, both in terms of work intensity and in who controls their labour. © 2015 John Wiley & Sons Ltd.

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.

A previously healthy 39-year-old woman suddenly became stuporous following a slight upper respiratory infection. She went into a coma within a few hours. On admission to our hospital, adenine arabinoside was administered upon the diagnosis of herpes simplex encephalitis, but it had no apparent effect. The patient showed moderate leukocytosis, but no other abnormal laboratory data. Serological examinations for virus titer were all negative. A CT scan on the 9th day showed a diffuse low-density area extending into the cerebral and cerebellar white matter, but no contrast-enhancement effect or midline shift was observed. She has since remained in a coma, and repeated CT scans have revealed marked ventricular dilatation. The clinical course, laboratory data, and CT findings suggest acute disseminated encephalomyelitis, but acute hemorrhagic leukoencephalitis cannot exactly be ruled out. Magnetic resonance imaging demonstrated a widespread white-matter lesion, while positron-emission CT demonstrated a dysfunction in both the white and gray matter. (author)

This paper reports orbital CT scans of 15 patients with clinically diagnoses traumatic cataracts retrospectively reviewed to determine the presence of radiographically detectable lens abnormalities. Definite lens swelling was clinically observed in a lease five cases. Eleven patients, scanned 4 hours of 3 days after injury, revealed visible and measured decreased CT density of the cataractous lens compared with the normal contralateral lens (average mean difference, 28 HU), suggesting acute lens swelling. In one patient, lens morphologic changes but not HU differences were found, probably due to superimposed hemorrhage. Three patients, scanned 3-8 hours after injury, revealed no detectable lens abnormality. The findings suggest that CT is potentially capable of identifying traumatic cataracts

Redox signaling in acute oxygen sensing

Directory of Open Access Journals (Sweden)

Lin Gao

2017-08-01

Full Text Available Acute oxygen (O2 sensing is essential for individuals to survive under hypoxic conditions. The carotid body (CB is the main peripheral chemoreceptor, which contains excitable and O2-sensitive glomus cells with O2-regulated ion channels. Upon exposure to acute hypoxia, inhibition of K+ channels is the signal that triggers cell depolarization, transmitter release and activation of sensory fibers that stimulate the brainstem respiratory center to produce hyperventilation. The molecular mechanisms underlying O2 sensing by glomus cells have, however, remained elusive. Here we discuss recent data demonstrating that ablation of mitochondrial Ndufs2 gene selectively abolishes sensitivity of glomus cells to hypoxia, maintaining responsiveness to hypercapnia or hypoglycemia. These data suggest that reactive oxygen species and NADH generated in mitochondrial complex I during hypoxia are signaling molecules that modulate membrane K+ channels. We propose that the structural substrates for acute O2 sensing in CB glomus cells are “O2-sensing microdomains” formed by mitochondria and neighboring K+ channels in the plasma membrane.

Cogan's syndrome mimicking acute Lyme arthritis.

Science.gov (United States)

Schwegmann, J P; Enzenauer, R J

1995-05-01

A pediatric case of Cogan's syndrome mimicking acute Lyme arthritis is described. A 12-year-old black boy was admitted to the pediatric service for presumed right knee septic arthritis. Symptoms included acute pain and swelling with decreased range-of-motion. Although the patient's right knee symptoms and positive Lyme serology were consistent with a diagnosis of Lyme arthritis, the presence of sensorineural hearing loss and interstitial keratitis with inflammatory arthritis suggested a diagnosis of Cogan's syndrome. Subsequent Western blot analysis was negative for Borrelia burgdorferi antigens. The patient had dramatic clinical improvement of musculoskeletal and ophthalmologic complaints shortly after receiving high-dose corticosteroids, although residual sensorineural hearing loss persisted.

The powers of suggestion: Albert Moll and the debate on hypnosis.

Science.gov (United States)

Maehle, Andreas-Holger

2014-03-01

The Berlin physician Albert Moll (1862-1939) was an advocate of hypnotic suggestion therapy and a prolific contributor to the medical, legal and public discussions on hypnotism from the 1880s to the 1920s. While his work in other areas, such as sexology, medical ethics and parapsychology, has recently attracted scholarly attention, this paper for the first time comprehensively examines Moll's numerous publications on hypnotism and places them in their contemporary context. It covers controversies over the therapeutic application of hypnosis, the reception of Moll's monograph Der Hypnotismus (1889), his research on the rapport between hypnotizer and subject, his role as an expert on 'hypnotic crime', and his views on the historical influence of hypnotism on the development of psychotherapy. My findings suggest that Moll rose to prominence due to the strong late-nineteenth-century public and medical interest in the phenomena of hypnosis, but that his work was soon overshadowed by new, non-hypnotic psychotherapeutic approaches, particularly Freud's psychoanalysis.

Bilateral Acute Angle-closure after Intraocular Surgery.

We report the case of a 75-year-old woman who developed an acute bilateral angle-closure associated with choroidal effusion a day after an uneventful cataract surgery. The same patient had undergone a similarly uneventful cataract surgery two weeks before, under the same protocol, with no postoperative complication in the other eye. Medical treatment, including the use of oral sulfamide-related drugs (acetazolamide), topical beta-blockers and steroids led to a gradual decrease in intraocular pressure (IOP) and choroidal effusion. Despite initial reports suggesting a link between sulfamide-exposure and these rare forms of angle-closure, our report would suggest a more complex pathophysiology behind this intriguing phenomenon.

Gastrointestinal helminthiasis in developing countries contributes to malnutrition and anemia. Diagnosis and treatment of helminthiasis, especially with low worm load is an unmet public health need in such settings. The infection may sometimes become manifest when a second pathology leads to purgation of the gastrointestinal tract. Two cases of helminthiasis are presented in which the infections only became amenable to diagnosis due to acute diarrhoea caused by giardiasis and lactulose administration. In the first case, acute giardiasis revealed Ascaris lumbricoides infestation, and in the second case primary helminthiasis (strongyloidiasis) was revealed by lactulose, and also led to Vibrio cholera bacteremia. These cases highlight the need to diagnose helminth infestations especially with low worm burdens by means of public health surveillance programmes. These cases highlight the need to diagnose helminth infestations especially with low worm burdens by means of public health surveillance programmes.

Acute renal failure after rifampicin

Full Text Available A patient with miliary tuberculosis and a chronic urogenital focus is described, who had a borderline renal function at diagnosis and developed overt renal failure upon daily treatment with rifampin (RMP, isoniazid (INH and ethambutol (EMB. This is the first Brazilian report of BMP induced renal damage. A renal biopsy taken on the third day of oliguria showed recent tubular necrosis with acute interstitial inflammation and granuloma formation. The aspect of the granulomatous lesion hightly suggested drug etiology because of the lack of palisading, high incidence of neutrophils and absence of facid-fast bacilli. This is the first presentation of an acute granulomatous interstitial nephritis probably due to RMP. Furthermore the pathogenesis of the renal damage caused by tuberculosis and RMP are discussed.

Hypokalemia is caused partly by intensive exercise. Some evidence suggests that psychological distress may cause hypokalemia. The relationship between the decline of serum potassium concentration and the level of symptoms of acute agitation, which was defined as a total score on a subset of six categories on the 18-item Brief Psychiatric Rating Scale (anxiety, tension, mannerism and posturing, hostility, uncooperativeness, psychomotor excitement), was examined in 313 schizophrenic men, admitted on an emergency basis during a 24-month period. In addition, change in serum potassium concentration after sedation was investigated. Serum potassium concentration in the severely agitated group was lower than that in the mild group. There was a significant correlation between serum potassium concentration and the level of symptoms of acute agitation (r = -0.30, P < 0.0001). Although the decline of serum potassium concentration in the patients who were sufficiently sedated improved within 8 h, that in the patients showing high scores on the acute agitation subset even 8 h after emergency admission was prolonged. Results indicate that sedation improves acute agitation-induced hypokalemia. rights

Intra-Carotid Urokinase thrombolytic therapy in acute cerebral infarction: a preliminary study

1990-01-01

We conducted a pilot study to evaluate the possibility that the intraarterial thrombolytic therapy might lead to recanalization of the acutely occluded cerebral arteries and subsequent clinical improvement in patients with acute cerebral infarction. Mean time from the onset of symptoms to the start of treatment and mean dosage of thrombolytic agent, Urokinase, were 6.4 hours and 1,260,000 units, respectively. Seven of 12 cases (58%) with acute cerebral infarction demonstrated successful recanalization. Neurological evaluation at one week and three months after the onset of symptoms suggested better outcome in the cases with recanalization. Repeat CT scan at 24 hours and one week after the procedure demonstrated the evidence of hemorrhagic infarction in the infarcted territories in five cases (41%), but clinical deteriorations were observed in only 2 cases. Though statistical analysis could not be done because the limited number of cases, these results suggest that the intraarterial thrombolytic therapy had a role in the management of acute cerebral infarction

Cortisol acutely reduces selective attention for erotic words in healthy young men.

Science.gov (United States)

Putman, Peter; Berling, Sylvia

Psychological stress prompts activity of the hypothalamic-pituitary-adrenal (HPA) axis resulting in increased release of cortisol. Long-term HPA aberrations have been observed for stress-related affective disorders but research into acute effects of cortisol on affect-regulation has only recently begun. Previous studies reported that exogenous cortisol acutely attenuated automatic attentional processing of task-irrelevant threatening information. This has been taken to suggest that cortisol may have acute anxiolytic properties, possibly through facilitating inhibition of threatening information. However, the role of cortisol in attentional inhibition of non-threatening arousing stimuli remained unclear. Therefore acute effects of 40 mg cortisol on performance of a masked and unmasked emotional Stroop task (EST) were assessed. Results for only the unmasked task demonstrated EST interference (interpreted as increased automatic attention) for erotic stimuli which was abolished by cortisol administration. This implies that effects of cortisol may not be restricted to attenuation of specifically anxiogenic information processing, as previously suggested. Copyright © 2011 Elsevier Ltd.

Eagar, K

1999-01-01

The Australian National Sub-Acute and Non-Acute Patient (AN-SNAP) Version 1 casemix classification was completed in 1997. AN-SNAP is designed for the classification of sub-acute and non-acute care provided in both inpatient and ambulatory settings and is intended to be useful for both funding and clinical management purposes. The National Sub-Acute and Non-Acute Casemix Classification study has produced the first version of a national classification of sub-acute and non-acute care. Ongoing refinement (leading to Version 2) will be possible through further analysis of the existing data set in combination with analysis of the results of a carefully planned and phased implementation.

Epidemiological studies have suggested an inverse correlation between red wine consumption and the incidence of CVD. However, Champagne wine has not been fully investigated for its cardioprotective potential. In order to assess whether acute and moderate Champagne wine consumption is capable of modulating vascular function, we performed a randomised, placebo-controlled, cross-over intervention trial. We show that consumption of Champagne wine, but not a control matched for alcohol, carbohydrate and fruit-derived acid content, induced an acute change in endothelium-independent vasodilatation at 4 and 8 h post-consumption. Although both Champagne wine and the control also induced an increase in endothelium-dependent vascular reactivity at 4 h, there was no significant difference between the vascular effects induced by Champagne or the control at any time point. These effects were accompanied by an acute decrease in the concentration of matrix metalloproteinase (MMP-9), a significant decrease in plasma levels of oxidising species and an increase in urinary excretion of a number of phenolic metabolites. In particular, the mean total excretion of hippuric acid, protocatechuic acid and isoferulic acid were all significantly greater following the Champagne wine intervention compared with the control intervention. Our data suggest that a daily moderate consumption of Champagne wine may improve vascular performance via the delivery of phenolic constituents capable of improving NO bioavailability and reducing matrix metalloproteinase activity.

Acute ischemic heart disease and interventional cardiology: a time for pause

Directory of Open Access Journals (Sweden)

Brophy James M

2006-10-01

Full Text Available Abstract Background A major change has occurred in the last few years in the therapeutic approach to patients presenting with all forms of acute coronary syndromes. Whether or not these patients present initially to tertiary cardiac care centers, they are now routinely referred for early coronary angiography and increasingly undergo percutaneous revascularization. This practice is driven primarily by the angiographic image and technical feasibility. Concomitantly, there has been a decline in expectant or ischemia-guided medical management based on specific clinical presentation, response to initial treatment, and results of noninvasive stratification. This 'tertiarization' of acute coronary care has been fuelled by the increasing sophistication of the cardiac armamentarium, the peer-reviewed publication of clinical studies purporting to show the superiority of invasive cardiac interventions, and predominantly supporting (non-peer-reviewed editorials, newsletters, and opinion pieces. Discussion This review presents another perspective, based on a critical reexamination of the evidence. The topics addressed are: reperfusion treatment of ST-elevation myocardial infarction; the indications for invasive intervention following thrombolysis; the role of invasive management in non-ST-elevation myocardial infarction and unstable angina; and cost-effectiveness and real world considerations. A few cases encountered in recent practice in community and tertiary hospitals are presented for illustrative purposes The numerous and far-reaching scientific, economic, and philosophical implications that are a consequence of this marked change in clinical practice as well as healthcare, decisional and conflict of interest issues are explored. Summary The weight of evidence does not support the contemporary unfocused broad use of invasive interventional procedures across the spectrum of acute coronary clinical presentations.

Organ protection possibilities in acute heart failure.

Unlike chronic heart failure (HF), the treatment for acute HF has not changed over the last decade. The drugs employed have shown their ability to control symptoms but have not achieved organ protection or managed to reduce medium to long-term morbidity and mortality. Advances in our understanding of the pathophysiology of acute HF suggest that treatment should be directed not only towards correcting the haemodynamic disorders and achieving symptomatic relief but also towards preventing organ damage, thereby counteracting myocardial remodelling and cardiac and extracardiac disorders. Compounds that exert vasodilatory and anti-inflammatory action in the acute phase of HF and can stop cell death, thereby boosting repair mechanisms, could have an essential role in organ protection.

An unusual cause of acute renal failure in sickle cell disease

Science.gov (United States)

Rockx, Marie-Antoinette; Gibson, Ian W.; Reslerova, Martina

2009-01-01

A young female with sickle cell disease was treated for biopsy-proven IgA nephropathy. Serum creatinine levels resolved to normal range, but a year later, she presented with oedema, hypertension and acute renal failure. A repeat renal biopsy showed acute-on-chronic thrombotic microangiopathy (TMA). We suggest that circulating microparticles could be a pathophysiological link between sickle cell disease and the development of renal TMA. This case emphasizes the importance of a further biopsy for acutely declining renal function, even when a definite diagnosis has been made from a previous biopsy. PMID:25949348

A teenager was admitted to an outside hospital ED following an episode of melena. He had been complaining of intermittent abdominal pain, nausea, malaise, and easy fatigability for 2 months, with significant worsening of symptoms 2 weeks prior to this episode. He had no significant medical, surgical, or family history. On presentation at the outside ED, he was found to be profoundly icteric and encephalopathic. Initial laboratories suggested anemia, acute kidney injury, and acute liver failure, leading to a presumptive diagnosis of acute fulminant liver failure necessitating transfer to our institution.

Acute pain services in India: A long and challenging journey ahead

2016-01-01

Full Text Available Acute post-operative pain and other forms of pain are widely undertreated globally including the Indian hospitals. As a result a large proportion of patients suffer from moderate to severe forms of pain. Undertreated pain can have many negative consequences such as pulmonary complications, acute myocardial ischemic events, delayed wound healing, prolonged hospital stay, etc. In spite of this acute pain continues to be negelected. The solution to poorly managed pain is not just developing newer and sophisticated techniques. But the solution lies in developing a dedicated, round-the-clock service called as acute pain service. This concept has gained world wide acceptance in last two decades and a majority of countries are developing such pain services in the hospitals. Unfortunately in India the field of acute pain medicine is still in its infancy. A very few hospitals have full fledged Acute Pain Services. In this review article we have tried to throw light on the hurdles in developing Acute Pain Services in our country. Also we have suggested a few possible solutions.

Finding privacy from a public death: a qualitative exploration of how a dedicated space for end-of-life care in an acute hospital impacts on dying patients and their families.

To explore the experiences and perceptions of hospital staff caring for dying patients in a dedicated patient/family room (named Lotus Room). Dying in hospital is a common outcome for people across the world. However, noise and activity in acute environments present barriers to quality end-of-life care. This is of concern because care provided to dying patients has been shown to affect both the patients and the bereaved families. A qualitative descriptive approach was used. Semi-structured interviews were conducted with 17 multidisciplinary staff and seven families provided information through an investigator-developed instrument. Qualitative data analysis generated three categories describing: Dying in an hospital; The Lotus Room; and the Outcomes for patients and families. The Lotus Room was seen as a large, private and, ultimately, safe space for patients and families within the public hospital environment. Family feedback supported staff perspectives that the Lotus Room facilitated family presence and communication. The privacy afforded by the Lotus Room within this acute hospital provided benefits for the dying patients and grieving families. Improved outcomes included a peaceful death for patients, which may have assisted the family with their bereavement.

Full Text Available Objective: To determine the effects of acute and chronic administration of methylprednisolone on oxidative stress, as quantified by measuring lipid peroxidation (LPO and total reactive antioxidant potential (TRAP, in rat lungs. Methods: Forty Wistar rats were divided into four groups: acute treatment, comprising rats receiving a single injection of methylprednisolone (50 mg/kg i.p.; acute control, comprising rats i.p. injected with saline; chronic treatment, comprising rats receiving methylprednisolone in drinking water (6 mg/kg per day for 30 days; and chronic control, comprising rats receiving normal drinking water. Results: The levels of TRAP were significantly higher in the acute treatment group rats than in the acute control rats, suggesting an improvement in the pulmonary defenses of the former. The levels of lung LPO were significantly higher in the chronic treatment group rats than in the chronic control rats, indicating oxidative damage in the lung tissue of the former. Conclusions: Our results suggest that the acute use of corticosteroids is beneficial to lung tissue, whereas their chronic use is not. The chronic use of methylprednisolone appears to increase lung LPO levels.

Full Text Available Context: Pithecellobium dulce (PD is an annual herbaceous plant commonly used in African traditional medicine as a purgative, antipyretic, anti-ulcer and wound dressing agent. Aims: To evaluate the acute and sub-acute toxicity of P. dulce stem bark hydroethanolic extract in Wistar rats. Methods: In the acute test, a single dose of 5 g/kg body weight was administered to Wistar rats afterwards they were observed individually 4 hours post-dosing, and at least once daily for 14 consecutive days. The sub-acute toxicity was evaluated by daily oral administration of 0.5 and 1 g/kg extract, for 28 days. Biochemical and hematological parameters assessment as well as body and organ weights of the rats were carried out. Results: The limit dose of 5 g/kg did not cause any mortality or signs of acute toxicity on the rats during the experimentation period. In the sub-acute test, uterus-ovary-trompe (UOT weight decreased dose-dependently: Control group (0.82 ± 0.03 g; Extract 0.5 g/kg (0.57 ± 0.06 g; Extract 1g/kg (0.48 ± 0.01 g (p ˂ 0.01. Extract lowered urea values in female group treated with 1 g/kg (p < 0.01. Lymphocytes percentage was dose dependently increased in treated male groups: Control group (53.00 ± 0.58%; extract 0.5 g/kg (58.67 ± 0.67% and extract 1 g/kg (60.67 ± 2.41%. Conclusions: These findings suggest that PD is relatively safe when administered orally in rats but is slightly atrophic for female reproductive organs.

Acute myocardial infarction is one of the leading causes of death in the world. This is also true in Cuba, where no national-level epidemiologic studies of related mortality have been published in recent years. Describe acute myocardial infarction mortality in Cuba from 1999 through 2008. A descriptive study was conducted of persons aged ≥25 years with a diagnosis of acute myocardial infarction from 1999 through 2008. Data were obtained from the Ministry of Public Health's National Statistics Division database for variables: age; sex; site (out of hospital, in hospital or in hospital emergency room) and location (jurisdiction) of death. Proportions, age- and sex-specific rates and age-standardized overall rates per 100,000 population were calculated and compared over time, using the two five-year time frames within the study period. A total of 145,808 persons who had suffered acute myocardial infarction were recorded, 75,512 of whom died, for a case-fatality rate of 51.8% (55.1% in 1999-2003 and 49.7% in 2004-2008). In the first five-year period, mortality was 98.9 per 100,000 population, falling to 81.8 per 100,000 in the second; most affected were people aged ≥75 years and men. Of Cuba's 14 provinces and special municipality, Havana, Havana City and Camagüey provinces, and the Isle of Youth Special Municipality showed the highest mortality; Holguín, Ciego de Ávila and Granma provinces the lowest. Out-of-hospital deaths accounted for the greatest proportion of deaths in both five-year periods (54.8% and 59.2% in 1999-2003 and 2004-2008, respectively). Although risk of death from acute myocardial infarction decreased through the study period, it remains a major health problem in Cuba. A national acute myocardial infarction case registry is needed. Also required is further research to help elucidate possible causes of Cuba's high acute myocardial infarction mortality: cardiovascular risk studies, studies of out-of-hospital mortality and quality of care

About 20% of cases of acute pancreatitis progress to a severe form, leading to high mortality rates. Several studies suggested methods to identify patients that will progress more severely. However, most studies present problems when used on daily practice. To assess the efficacy of the PANC 3 score to predict acute pancreatitis severity and its relation to clinical outcome. Acute pancreatitis patients were assessed as to sex, age, body mass index (BMI), etiology of pancreatitis, intensive care need, length of stay, length of stay in intensive care unit and mortality. The PANC 3 score was determined within the first 24 hours after diagnosis and compared to acute pancreatitis grade of the Revised Atlanta classification. Out of 64 patients diagnosed with acute pancreatitis, 58 met the inclusion criteria. The PANC 3 score was positive in five cases (8.6%), pancreatitis progressed to a severe form in 10 cases (17.2%) and five patients (8.6%) died. Patients with a positive score and severe pancreatitis required intensive care more often, and stayed for a longer period in intensive care units. The PANC 3 score showed sensitivity of 50%, specificity of 100%, accuracy of 91.4%, positive predictive value of 100% and negative predictive value of 90.6% in prediction of severe acute pancreatitis. The PANC 3 score is useful to assess acute pancreatitis because it is easy and quick to use, has high specificity, high accuracy and high predictive value in prediction of severe acute pancreatitis.

Full Text Available Objective: To identify the current evidence for acute low back pain (LBP treatment techniques and to amalgamate this information into a clinically applicable algorithm for South African physiotherapists.Study design: Systematic review.Methods: Computerized bibliographical databases were systematically searched during September 2006 and October 2006 for primary and secondary research reporting on the efficacy of various physiotherapeutic treatment techniques for acute LBP. A search for clinical guidelines regarding acute LBP was also undertaken. Evidence levels were allocated to the primary and secondary research retrieved. Results: Twenty-one systematic reviews, four randomized controlled trials and eleven clinical guidelines were included in this review. There is Level 1 evidence that advice to stay active, McKenzie preferential exercises and spinal manipulative therapy (up to six weeks is beneficial in the initial treatment of acute LBP. There is level 2 evidence that stability exercises, dry needling, heat wrap with exercises, cognitive behavioural therapy, printed patient education, massage (with education and exercises, and lifestyle modification might be potentially beneficial in the treatment of acute LBP. There is level 1 evidence that bed rest should not be recommended for simple acute LBP.  Should a patient not resolve in six weeks, red and yellow flags should be re-assessed, or patient should be referred to a specialist. Outcome: Based on the current evidence, a composite algorithm was developed to assist South African physiotherapists when making treatment decisions for acute LBP. Conclusion: There seems to be a lack of evidence for the efficacy of common treatment techniques used by physiotherapists in the management of acute LBP, indicating an urgent need for physiotherapy-specific, high-quality clinical trials. It is suggested that the evidence-based algorithm that has been developed, be used in the management of acute LBP to

2011-08-01

Full Text Available Abstract Introduction The potential of alcohol withdrawal to cause acute coronary events is an area that needs the urgent attention of clinicians and researchers. Case presentation We report the case of a 52-year-old heavy-alcohol-using Sri Lankan man who developed electocardiogram changes suggestive of an acute coronary event during alcohol withdrawal. Despite the patient being asymptomatic, subsequent echocardiogram showed evidence of ischemic myocardial dysfunction. We review the literature on precipitation of myocardial ischemia during alcohol withdrawal and propose possible mechanisms. Conclusions Alcohol withdrawal is a commonly observed phenomenon in hospitals. However, the number of cases reported in the literature of acute coronary events occurring during withdrawal is few. Many cases of acute ischemia or sudden cardiac deaths may be attributed to other well known complications of delirium tremens. This is an area needing the urgent attention of clinicians and epidemiologists.

Driving Toward Precision Medicine for Acute Leukemias: Are We There Yet?

Despite recent progress in the understanding of the molecular basis of acute leukemias, treatment options for these diseases have not changed significantly over the last few decades. We present a nonexhaustive summary of the current cytogenetic and molecular changes associated with acute leukemias in disease prognostication and potential targeted therapies. An emerging paradigm is that many genetic or molecular alterations target similar signal transduction, transcriptional, and epigenetic pathways. Some of these targets may be used as predictive biomarkers for the development of novel targeted therapies that depart significantly from conventional chemotherapy, the current mainstay for the treatment of acute leukemias. Established leukemia-specific predictive biomarkers for precision medicine include those genetic lesions such as BCR-ABL1 for Philadelphia-positive acute lymphoblastic leukemia and PML-RARα for acute promyelocytic leukemia. Evidence indicates that targeted therapy for FLT-ITD gene mutations with small-molecule tyrosine kinase inhibitors can extend its use from relapsed disease to up-front induction therapy. Core-binding factor acute myeloid leukemia in adults predicts benefit with high-dose cytarabine in the absence of KIT mutation. Although risk-adapted therapy based on genetic abnormalities in acute leukemias has allowed the beginning of personalized treatment and selective use of hematopoietic stem cell transplantation, the prognostic and/or predictive value of many novel mutations of the acute leukemic genome is yet to be elucidated. Many challenges lie ahead in targeted therapies due to overlapping of chromosomal and molecular lesions as well as other limiting factors. Future work should focus on the understanding of pathogenetic changes that lead to leukemogenesis, which may guide the rational design of new targeted therapies and make the drive toward precision medicine for acute leukemias one step closer. © 2017 Pharmacotherapy Publications

Burden of disease studies intend to improve public health decision-making and to measure social and economic impact in population. The objective of this study was to describe the burden of acute respiratory infections (ARI) in Ecuador between 2011 and 2015. Five-year period morbidity and mortality data available from national agencies of statistics was analyzed to estimate the burden of disease attributable to acute respiratory infections. Cases and deaths registered were grouped according to their ICD-10 code into three diagnostic groups: Acute upper respiratory infections (J00-J06), Influenza and pneumonia (J09-J18), and Bronchitis and other acute lower respiratory infections (J20-J22, J85, J86). Disability-adjusted life years stratified by diagnostic and age group were calculated using the "DALY" package for R. The productivity loss in monetary terms was estimated using the human capital method. Over the 5-year period studied there were a total of 14.84 million cases of acute respiratory infections, with 17 757 deaths reported (0.12%). The yearly burden of disease ranged between 98 944 to 118 651 disability-adjusted life years, with an estimated average loss of productivity of US$152.16 million (±19.6) per year. Approximately 99% of the burden can be attributed to years life lost due to premature mortality in population under 5 years old and over 60 years-old. The burden of acute respiratory infections remained steady during the analyzed period. Evidence-based prevention and control policies to tackle acute respiratory infections in Ecuador should focus on the population at extreme ages of life.

Acute otitis externa, also known as ‘swimmer’s ear’, is a common disease of children, adolescents and adults. While chronic suppurative otitis media or acute otitis media with tympanostomy tubes or a perforation can cause acute otitis externa, both the infecting organisms and management protocol are different. This practice point focuses solely on managing acute otitis externa, without acute otitis media, tympanostomy tubes or a perforation being present.

The powers of suggestion: Albert Moll and the debate on hypnosis

Science.gov (United States)

Maehle, Andreas-Holger

2014-01-01

The Berlin physician Albert Moll (1862–1939) was an advocate of hypnotic suggestion therapy and a prolific contributor to the medical, legal and public discussions on hypnotism from the 1880s to the 1920s. While his work in other areas, such as sexology, medical ethics and parapsychology, has recently attracted scholarly attention, this paper for the first time comprehensively examines Moll’s numerous publications on hypnotism and places them in their contemporary context. It covers controversies over the therapeutic application of hypnosis, the reception of Moll’s monograph Der Hypnotismus (1889), his research on the rapport between hypnotizer and subject, his role as an expert on ‘hypnotic crime’, and his views on the historical influence of hypnotism on the development of psychotherapy. My findings suggest that Moll rose to prominence due to the strong late-nineteenth-century public and medical interest in the phenomena of hypnosis, but that his work was soon overshadowed by new, non-hypnotic psychotherapeutic approaches, particularly Freud’s psychoanalysis.

Augmented neuroendocrine stress responses and altered immune functions may play a role in the manifestation of functional gastrointestinal (GI) disorders. We tested the hypothesis that IBS patients would demonstrate enhanced psychological and endocrine responses, as well as altered stress-induced redistribution of circulating leukocytes and lymphocytes, in response to an acute psychosocial stressor when compared with healthy controls. Responses to public speaking stress were analyzed in N = 17 IBS patients without concurrent psychiatric conditions and N = 12 healthy controls. At baseline, immediately following public speaking, and after a recovery period, state anxiety, acute GI symptoms, cardiovascular responses, serum cortisol and plasma adrenocorticotropic hormone (ACTH) were measured, and numbers of circulating leukocytes and lymphocyte subpopulations were analyzed by flow cytometry. Public speaking led to significant cardiovascular activation, a significant increase in ACTH, and a redistribution of circulating leukocytes and lymphocyte subpopulations, including significant increases in natural killer cells and cytotoxic/suppressor T cells. IBS patients demonstrated significantly greater state anxiety both at baseline and following public speaking. However, cardiovascular and endocrine responses, as well as the redistribution of circulating leukocytes and lymphocyte subpopulations after public speaking stress, did not differ for IBS patients compared with controls. In IBS patients without psychiatric comorbidity, the endocrine response as well as the circulation pattern of leukocyte subpopulations to acute psychosocial stress do not differ from healthy controls in spite of enhanced emotional responses. Future studies should discern the role of psychopathology in psychological and biological stress responses in IBS.

blood volume with increase of blood volume in the superior sagitta sinus during cerebral vasoparesis under intracranial hypertension is presumed. It is suggested from the superior sagittal sinus pressure in various experimental groups that the site, reactivity and disturbed degree of the cerebral venous system are changed by the difference of respiratory or ventrilatory state and the cerebral venous circulatory disturbance has also reference to the occurrence of acute brain swelling. 3) During cerebral vasopareris under acute intracranial hypertension, remarkable supression of respiration, increased central venous pressure and increased common carotid blood flow were observed. It is concluded that the reaction of systemic hemodynamics following respiratory change effects on cerebral circulation markedly and they are being important factors to occurrence of acute brain swelling.

There is a need to develop other casemix classifications, apart from DRG for sub-acute and non-acute inpatient care payment mechanism in Thailand. To develop a casemix classification for sub-acute and non-acute inpatient service. The study began with developing a classification system, analyzing cost, assigning payment weights, and ended with testing the validity of this new casemix system. Coefficient of variation, reduction in variance, linear regression, and split-half cross-validation were employed. The casemix for sub-acute and non-acute inpatient services contained 98 groups. Two percent of them had a coefficient of variation of the cost of higher than 1.5. The reduction in variance of cost after the classification was 32%. Two classification variables (physical function and the rehabilitation impairment categories) were key determinants of the cost (adjusted R2 = 0.749, p = .001). Validity results of split-half cross-validation of sub-acute and non-acute inpatient service were high. The present study indicated that the casemix for sub-acute and non-acute inpatient services closely predicted the hospital resource use and should be further developed for payment of the inpatients sub-acute and non-acute phase.

2012-01-01

Environmental radiation monitoring in Kenya was started in 1990 following the 1979 Three Mile Island and the 1986 Chernobyl nuclear power plants accidents. The main purpose was to measure the radioactivity of foodstuffs imported from oversees and to carry out environmental radiation monitoring of soil, rock, water and air sample to check for contamination. Through environmental radiation monitoring, the Food and Environmental Monitoring Section (FEM) of the Kenya Radiation Protection Board (RPB) works to protect the public and environment from hazards associated with ionizing radiation. The purpose of this paper was to highlight suggestions for the improvement of environmental radiation monitoring in Kenya with respect to protecting the public and the environment against undue radiation risk by ensuring that potential exposures are kept As Low As Reasonably Achievable (ALARA). The suggestions for improvement will serve as a guideline for the strengthening of environmental radiation monitoring program in Kenya

Suggestibility and suggestive modulation of the Stroop effect.

Science.gov (United States)

Kirsch, Irving

2011-06-01

Although the induction of a hypnotic state does not seem necessary for suggestive modulation of the Stroop effect, this important phenomenon has seemed to be dependent on the subject's level of hypnotic suggestibility. Raz and Campbell's (2011) study indicates that suggestion can modulate the Stroop effect substantially in very low suggestible subjects, as well as in those who are highly suggestible. This finding casts doubt on the presumed mechanism by which suggestive modulation is brought about. Research aimed at uncovering the means by which low suggestible individuals are able to modulate the Stroop effect would be welcome, as would assessment of this effect in moderately suggestible people.

Loneliness and acute stress reactivity: A systematic review of psychophysiological studies.

Brown, Eoin G; Gallagher, Stephen; Creaven, Ann-Marie

2018-05-01

Physiological reactivity to acute stress has been proposed as a potential biological mechanism by which loneliness may lead to negative health outcomes such as cardiovascular disease. This review was conducted to investigate the association between loneliness and physiological responses to acute stress. A series of electronic databases were systematically searched (PsycARTICLES, PsycINFO, Medline, CINAHL Plus, EBSCOhost, PubMed, SCOPUS, Web of Science, Science Direct) for relevant studies, published up to October 2016. Eleven studies were included in the review. Overall, the majority of studies reported positive associations between loneliness and acute stress responses, such that higher levels of loneliness were predictive of exaggerated physiological reactions. However, in a few studies, loneliness was also linked with decreased stress responses for particular physiological outcomes, indicating the possible existence of blunted relationships. There was no clear pattern suggesting any sex- or stressor-based differences in these associations. The available evidence supports a link between loneliness and atypical physiological reactivity to acute stress. A key finding of this review was that greater levels of loneliness are associated with exaggerated blood pressure and inflammatory reactivity to acute stress. However, there was some indication that loneliness may also be related to blunted cardiac, cortisol, and immune responses. Overall, this suggests that stress reactivity could be one of the biological mechanisms through which loneliness impacts upon health. © 2017 Society for Psychophysiological Research.

Acute psychophysiological stress impairs human associative learning.

Science.gov (United States)

Ehlers, M R; Todd, R M

2017-11-01

Addiction is increasingly discussed asa disorder of associative learning processes, with both operant and classical conditioning contributing to the development of maladaptive habits. Stress has long been known to promote drug taking and relapse and has further been shown to shift behavior from goal-directed actions towards more habitual ones. However, it remains to be investigated how acute stress may influence simple associative learning processes that occur before a habit can be established. In the present study, healthy young adults were exposed to either acute stress or a control condition half an hour before performing simple classical and operant conditioning tasks. Psychophysiological measures confirmed successful stress induction. Results of the operant conditioning task revealed reduced instrumental responding under delayed acute stress that resembled behavioral responses to lower levels of reward. The classical conditioning experiment revealed successful conditioning in both experimental groups; however, explicit knowledge of conditioning as indicated by stimulus ratings differentiated the stress and control groups. These findings suggest that operant and classical conditioning are differentially influenced by the delayed effects of acute stress with important implications for the understanding of how new habitual behaviors are initially established.

1994-07-01

We have identified and characterized a previously unrecognized form of acute leukemia that shares features of both myeloid and natural killer (NK) cells. From a consecutive series of 350 cases of adult de novo acute myeloid leukemia (AML), we identified 20 cases (6%) with a unique immunophenotype: CD33+, CD56+, CD11a+, CD13lo, CD15lo, CD34+/-, HLA-DR-, CD16-. Multicolor flow cytometric assays confirmed the coexpression of myeloid (CD33, CD13, CD15) and NK cell-associated (CD56) antigens in each case, whereas reverse transcription polymerase chain reaction (RT-PCR) assays confirmed the identity of CD56 (neural cell adhesion molecule) in leukemic blasts. Although two cases expressed CD4, no case expressed CD2, CD3, or CD8 and no case showed clonal rearrangement of genes encoding the T-cell receptor (TCR beta, gamma, delta). Leukemic blasts in the majority of cases shared unique morphologic features (deeply invaginated nuclear membranes, scant cytoplasm with fine azurophilic granularity, and finely granular Sudan black B and myeloperoxidase cytochemical reactivity) that were remarkably similar to those of acute promyelocytic leukemia (APL); particularly the microgranular variant (FAB AML-M3v). However, all 20 cases lacked the t(15;17) and 17 cases tested lacked the promyelocytic/retinoic acid receptor alpha (RAR alpha) fusion transcript in RT-PCR assays; 12 cases had 46,XX or 46,XY karyotypes, whereas 2 cases had abnormalities of chromosome 17q: 1 with del(17)(q25) and the other with t(11;17)(q23;q21) and the promyelocytic leukemia zinc finger/RAR alpha fusion transcript. All cases tested (6/20), including the case with t(11;17), failed to differentiate in vitro in response to all-trans retinoic acid (ATRA), suggesting that these cases may account for some APLs that have not shown a clinical response to ATRA. Four of 6 cases tested showed functional NK cell-mediated cytotoxicity, suggesting a relationship between these unique CD33+, CD56+, CD16- acute leukemias and

Damian Hoy

2014-11-01

Full Text Available Objective: In September 2012, there was an unexpected increase of acute febrile illness (AFI in Chuuk State of the Federated States of Micronesia. At the same time, dengue outbreaks were occurring in two of the Federated States of Micronesia’s other three states. The cause of AFI was suspected to be dengue; however, by the end of October, only one of 39 samples was positive for dengue. The objective of the investigation was to establish the cause of the outbreak. Methods: A line list was created and data analysed by time, place, person and clinical features. Reported symptoms were compared with the published symptoms of several diagnoses and laboratory testing undertaken. Results: Of the 168 suspected cases, 62% were less than 20 years of age and 60% were male. The clinical features of the cases were not typical for dengue but suggestive of respiratory illness. Nasopharyngeal swabs were subsequently collected and found to be positive for influenza. Public health measures were undertaken and the AFI returned to expected levels. Discussion: Clinical diagnosis of acute febrile illness (AFI can often be difficult and misleading. This can mean that opportunities for preventive measures early on in an outbreak are missed. In any outbreak, descriptive epidemiological analyses are valuable in helping to ascertain the cause of the outbreak.

The aim of the study was to determine whether an oral treatment with a commercial pharmaceutical product containing Saccharomyces boulardii would reduce the duration of diarrhea in infants with acute diarrhea. In the present double-blind, placebo-controlled study, 186 infants, 6 to 48 months old and hospitalized within 72 hours after the onset of acute diarrhea in 2 hospitals in Goiânia, Goiás, Brazil, were randomly assigned to receive twice per day for 5 days 200 mg of a commercial pharmaceutical product containing 4 × 10 viable cells of S boulardii or a placebo. Stool samples were submitted to search for rotavirus. Among the 176 infants who completed the trial, those treated with S boulardii (90) showed a reduction in diarrhea duration (P boulardii was given to children within 72 hours after the onset of acute diarrhea. The present study suggests a complementary treatment of acute diarrhea in infants with daily oral doses of S boulardii.

Since these changes can be caused by a decreased density of perfused brain capillaries, we used 30 adult male Wistar rats to study the effect of acute and chronic hyperglycemia on (1) the brain intravascular space using radioiodinated albumin, (2) the anatomic density of brain capillaries using alkaline phosphatase histochemistry, and (3) the fraction of brain capillaries that are perfused using the fluorescein isothiocyanate-dextran method. Our results indicate that acute and chronic hyperglycemia do not affect the brain intravascular space nor the anatomic density of brain capillaries. Also, there were no differences in capillary recruitment among normoglycemic, acutely hyperglycemic, and chronically hyperglycemic rats. These results suggest that the shrinkage of the brain L-glucose space in chronic hyperglycemia is more likely due to changes in the blood-brain barrier permeability to L-glucose

To assess the costs of hospital accreditation in Australia. Mixed methods design incorporating: stakeholder analysis; survey design and implementation; activity-based costs analysis; and expert panel review. Acute care hospitals accredited by the Australian Council for Health Care Standards. Six acute public hospitals across four States. Accreditation costs varied from 0.03% to 0.60% of total hospital operating costs per year, averaged across the 4-year accreditation cycle. Relatively higher costs were associated with the surveys years and with smaller facilities. At a national level these costs translate to $A36.83 million, equivalent to 0.1% of acute public hospital recurrent expenditure in the 2012 fiscal year. This is the first time accreditation costs have been independently evaluated across a wide range of hospitals and highlights the additional cost burden for smaller facilities. A better understanding of the costs allows policymakers to assess alternative accreditation and other quality improvement strategies, and understand their impact across a range of facilities. This methodology can be adapted to assess international accreditation programmes. Published by the BMJ Publishing Group Limited.

Serum angiotensin-converting enzyme (SACE) levels were measured in 44 subjects six weeks after acute pulmonary histoplasmosis. All patients were infected in a common-source outbreak of histoplasmosis which occurred on one day. All patients had both strictly defined clinical and serologic evidence of infection. The SACE activity was elevated at six weeks compared to normal controls, and seven of the 44 had levels more than 2 SD above the normal mean. SACE levels were also measured at three and 24 weeks after acute infection in a smaller number of the same subjects. Serial observations demonstrated that all subjects (including those with normal and elevated SACE at six weeks) had a rise and fall in SACE activity following symptomatic acute pulmonary histoplasmosis. Our findings suggest that elevated SACE does not reliably separate sarcoidosis from histoplasmosis, although elevations in histoplasmosis are much less common and may occur only briefly following acute pulmonary histoplasmosis. More important, it seems that SACE activity rises acutely in all patients with symptomatic acute histoplasmosis and then falls gradually toward baseline over several months, coinciding temporally with the granulomatous response.

Evaluation of quality of care is an integral part of modern healthcare, and has become an indispensable tool for health authorities, the public, the press and patients. However, measuring quality of care is difficult, because it is a multifactorial and multidimensional concept that cannot be estimated solely on the basis of patients' clinical outcomes. Thus, measuring the process of care through quality indicators (QIs) has become a widely used practice in this context. Other professional societies have published QIs for the evaluation of quality of care in the context of acute myocardial infarction (AMI), but no such indicators exist in Europe. In this context, the European Society of Cardiology (ESC) Acute Cardiovascular Care Association (ACCA) has reflected on the measurement of quality of care in the context of AMI (ST segment elevation myocardial infarction (STEMI) and non-ST segment elevation myocardial infarction (NSTEMI)) and created a set of QIs, with a view to developing programmes to improve quality of care for the management of AMI across Europe. We present here the list of QIs defined by the ACCA, with explanations of the methodology used, scientific justification and reasons for the choice for each measure.

Acute gallbladder torsion - a continued pre-operative diagnostic dilemma

Directory of Open Access Journals (Sweden)

Desrochers Randal

2011-04-01

Full Text Available Abstract Acute gallbladder volvulus continues to remain a relatively uncommon process, manifesting itself usually during exploration for an acute surgical abdomen with a presumptive diagnosis of acute cholecystitis. The pathophysiology is that of mechanical organo-axial torsion along the gallbladder's longitudinal axis involving the cystic duct and cystic artery, and with a pre-requisite of local mesenteric redundancy. The demographic tendency is septua- and octo-genarians of the female sex, and its overall incidence is increasing, this being attributed to increasing life expectancy. We discuss two cases of elderly, fragile women presenting to the emergency department complaining of sudden onset right upper quadrant abdominal pain. Their subsequent evaluation suggested acute cholecystitis. Ultimately both were taken to the operating room where the correct diagnosis of gallbladder torsion was made. Pre-operative diagnosis continues to be a major challenge with only 4 cases reported in the literature diagnosed with pre-operative imaging; the remainder were found intra-operatively. Consequently, a delay in diagnosis can have devastating patient outcomes. Herein we propose a necessary high index of suspicion for gallbladder volvulus in the outlined patient demographic with symptoms and signs mimicking acute cholecystitis.

In people with acute pancreatitis, it is unclear what the role should be for medical treatment as an addition to supportive care such as fluid and electrolyte balance and organ support in people with organ failure. To assess the effects of different pharmacological interventions in people with acute pancreatitis. We searched the Cochrane Central Register of Controlled Trials (CENTRAL, 2016, Issue 9), MEDLINE, Embase, Science Citation Index Expanded, and trial registers to October 2016 to identify randomised controlled trials (RCTs). We also searched the references of included trials to identify further trials. We considered only RCTs performed in people with acute pancreatitis, irrespective of aetiology, severity, presence of infection, language, blinding, or publication status for inclusion in the review. Two review authors independently identified trials and extracted data. We did not perform a network meta-analysis as planned because of the lack of information on potential effect modifiers and differences of type of participants included in the different comparisons, when information was available. We calculated the odds ratio (OR) with 95% confidence intervals (CIs) for the binary outcomes and rate ratios with 95% CIs for count outcomes using a fixed-effect model and random-effects model. We included 84 RCTs with 8234 participants in this review. Six trials (N = 658) did not report any of the outcomes of interest for this review. The remaining 78 trials excluded 210 participants after randomisation. Thus, a total of 7366 participants in 78 trials contributed to one or more outcomes for this review. The treatments assessed in these 78 trials included antibiotics, antioxidants, aprotinin, atropine, calcitonin, cimetidine, EDTA (ethylenediaminetetraacetic acid), gabexate, glucagon, iniprol, lexipafant, NSAIDs (non-steroidal anti-inflammatory drugs), octreotide, oxyphenonium, probiotics, activated protein C, somatostatin, somatostatin plus omeprazole, somatostatin

Update on the Management of Pediatric Acute Osteomyelitis and Septic Arthritis

Directory of Open Access Journals (Sweden)

Luca Castellazzi

2016-06-01

Full Text Available Acute osteomyelitis and septic arthritis are two infections whose frequencies are increasing in pediatric patients. Acute osteomyelitis and septic arthritis need to be carefully assessed, diagnosed, and treated to avoid devastating sequelae. Traditionally, the treatment of acute osteoarticular infection in pediatrics was based on prolonged intravenous anti-infective therapy. However, results from clinical trials have suggested that in uncomplicated cases, a short course of a few days of parenteral antibiotics followed by oral therapy is safe and effective. The aim of this review is to provide clinicians an update on recent controversies and advances regarding the management of acute osteomyelitis and septic arthritis in children. In recent years, the emergence of bacterial species resistant to commonly used antibiotics that are particularly aggressive highlights the necessity for further research to optimize treatment approaches and to develop new molecules able to fight the war against acute osteoarticular infection in pediatric patients.

Antimicrobial resistance is a worldwide threat to public health. Acute respiratory tract infections are the main reason for antibiotic prescribing in the Spanish paediatric population. The aim of the study was to describe the frequency of antibiotic prescription and their pattern of use in acute respiratory tract infections diagnosed in children in Primary Care in Aragón (Spain). A study was conducted over a 1-year period on children between 0 and 14 years-old, recording all episodes of acute otitis, acute pharyngotonsillitis, non-specific upper respiratory infection, and acute bronchitis. The proportion of episodes within each diagnosis receiving an antibiotic prescription was calculated, and the prescribing pattern was determined. Half (50%) of the children in Aragón were diagnosed with a respiratory tract infection during the study period. Non-specific upper respiratory infection was the most frequent diagnosis. An antibiotic was prescribed in 75% of pharyngotonsillitis episodes, 72% of otitis, 27% of bronchitis, and 16% of non-specific upper respiratory infections. Broad spectrum antibiotics, mainly amoxicillin and amoxicillin-clavulanic, were predominantly prescribed. Antibiotic prescribing in respiratory tract infections in children was generally high, and the choice of antibiotics was probably inappropriate in a high percentage of cases. Therefore an improvement in antibiotic prescribing in children appears to be needed. Copyright © 2014 Asociación Española de Pediatría. Published by Elsevier España, S.L.U. All rights reserved.

Predictors of early arrival at the emergency department in acute ischaemic stroke.

LENUS (Irish Health Repository)

Curran, C

2012-01-31

BACKGROUND: A requirement of an effective acute stroke service is the early arrival of patients to the hospital emergency department (ED). This will allow the possible use of thrombolytic therapy or other acute interventions within a limited time window. AIMS: We investigated the predictors of early arrival in a single hospital serving a mixed urban and rural catchment area. METHODS: A retrospective review of all case notes for 1 year was performed. RESULTS: Of 105 acute strokes, 91 were cerebral infarcts and a total of 71 cases presenting initially to the ED had timing available for analysis. 39.4% presented within 3 h, and 12.7% were potentially suitable for thrombolysis. Those living closer to the hospital were not more likely to arrive within 3 h (Z = -0.411, p = 0.68). Presenting directly to the hospital by emergency services (or private transport) was significantly associated with early arrival in a univariate comparison (p < 0.001), and in a multivariate model. CONCLUSION: The only independent predictor of early arrival to the ED is direct presentation. Improved public education of the importance of recognition of stroke symptoms and rapid contact with the emergency services will improve the early attendance following acute stroke, allowing increased use of acute stroke treatments.

Acute stress may induce ovulation in women

Directory of Open Access Journals (Sweden)

Cano Antonio

2010-05-01

Full Text Available Abstract Background This study aims to gather information either supporting or rejecting the hypothesis that acute stress may induce ovulation in women. The formulation of this hypothesis is based on 2 facts: 1 estrogen-primed postmenopausal or ovariectomized women display an adrenal-progesterone-induced ovulatory-like luteinizing hormone (LH surge in response to exogenous adrenocorticotropic hormone (ACTH administration; and 2 women display multiple follicular waves during an interovulatory interval, and likely during pregnancy and lactation. Thus, acute stress may induce ovulation in women displaying appropriate serum levels of estradiol and one or more follicles large enough to respond to a non-midcycle LH surge. Methods A literature search using the PubMed database was performed to identify articles up to January 2010 focusing mainly on women as well as on rats and rhesus monkeys as animal models of interaction between the hypothalamic-pituitary-adrenal (HPA and hypothalamic-pituitary-gonadal (HPG axes. Results Whereas the HPA axis exhibits positive responses in practically all phases of the ovarian cycle, acute-stress-induced release of LH is found under relatively high plasma levels of estradiol. However, there are studies suggesting that several types of acute stress may exert different effects on pituitary LH release and the steroid environment may modulate in a different way (inhibiting or stimulating the pattern of response of the HPG axis elicited by acute stressors. Conclusion Women may be induced to ovulate at any point of the menstrual cycle or even during periods of amenorrhea associated with pregnancy and lactation if exposed to an appropriate acute stressor under a right estradiol environment.

2006-01-01

Full Text Available Abstract Background In Tanzania, oral health services are mostly in the form of dental extractions aimed at alleviating acute dental pain. Conservative methods of alleviating acute dental pain are virtually non-existent. Therefore, it was the aim of this study to determine treatment success of emergency pulpotomy in relieving acute dental pain. Methods Setting: School of Dentistry, Muhimbili National Hospital, Dar es Salaam, Tanzania. Study design: Longitudinal study. Participants: 180 patients who presented with dental pain due to acute irreversible pulpitis during the study period between July and August 2001. Treatment and evaluation: Patients were treated by emergency pulpotomy on permanent posterior teeth and were evaluated for pain after one, three and six week's post-treatment. Pain, if present, was categorised as either mild or acute. Results Of the patients with treated premolars, 25 (13.9% patients did not experience pain at all while 19 (10.6% experienced mild pain. None of the patients with treated premolars experienced acute pain. Among 136 patients with treated molars 56 (31% did not experience any pain, 76 (42.2% experienced mild pain and the other 4 (2.2% suffered acute pain. Conclusion The short term treatment success of emergency pulpotomy was high being 100% for premolars and 97.1% for molars, suggesting that it can be recommended as a measure to alleviate acute dental pain while other conservative treatment options are being considered.

Notch signaling inhibitor DAPT provides protection against acute craniocerebral injury.

Directory of Open Access Journals (Sweden)

Hong-Mei Zhang

Full Text Available Notch signaling pathway is involved in many physiological and pathological processes. The γ-secretase inhibitor DAPT inhibits Notch signaling pathway and promotes nerve regeneration after cerebral ischemia. However, neuroprotective effects of DAPT against acute craniocerebral injury remain unclear. In this study, we established rat model of acute craniocerebral injury, and found that with the increase of damage grade, the expression of Notch and downstream protein Hes1 and Hes5 expression gradually increased. After the administration of DAPT, the expression of Notch, Hes1 and Hes5 was inhibited, apoptosis and oxidative stress decreased, neurological function and cognitive function improved. These results suggest that Notch signaling can be used as an indicator to assess the severity of post-traumatic brain injury. Notch inhibitor DAPT can reduce oxidative stress and apoptosis after acute craniocerebral injury, and is a potential drug for the treatment of acute craniocerebral injury.

Since the 2006 Pandemic Influenza Preparedness and Response Plan according to the World Health Organization’s recommendation, the Republic of Korea has prepared and periodically evaluated the plan to respond to various public health crises including pandemic influenza. Korea has stockpiled 13,000,000 doses of antiviral drugs covering 26% of the Korean population and runs 519 isolated beds in 16 medical institutions. The division of public health crisis response in Korea Centers for Disease Control and Prevention are in charge of responding to public health crises caused by emerging infectious diseases including severe acute respiratory syndrome, avian influenza human infection, and pandemic influenza. Its job description includes preparing for emerging infectious diseases, securing medical resources during a crisis, activating the emergency response during the crisis, and fortification of capabilities of public health personnel. It could evolve into a comprehensive national agency to deal with public health crisis based on the experience of previous national emerging infectious diseases. PMID:24298444

Acute stress has been shown to enhance learning and memory ability, predominantly through the action of corticosteroid stress hormones. However, the valuable targets for promoting learning and memory induced by acute stress and the underlying molecular mechanisms remain unclear. Acid-sensing ion channels (ASICs) play an important role in central neuronal systems and involves in depression, synaptic plasticity and learning and memory. In the current study, we used a combination of electrophysiological and behavioral approaches in an effort to explore the effects of acute stress on ASICs. We found that corticosterone (CORT) induced by acute stress caused a potentiation of ASICs current via glucocorticoid receptors (GRs) not mineralocorticoid receptors (MRs). Meanwhile, CORT did not produce an increase of ASICs current by pretreated with GF109203X, an antagonist of protein kinase C (PKC), whereas CORT did result in a markedly enhancement of ASICs current by bryostatin 1, an agonist of PKC, suggesting that potentiation of ASICs function may be depended on PKC activating. More importantly, an antagonist of ASICs, amiloride (10 μM) reduced the performance of learning and memory induced by acute stress, which is further suggesting that ASICs as the key components involves in cognitive processes induced by acute stress. These results indicate that acute stress causes the enhancement of ASICs function by activating PKC signaling pathway, which leads to potentiated learning and memory. Copyright © 2018 Elsevier Inc.

2011-01-01

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

Magnesium sulfate infusion for acute asthma in the emergency department

Directory of Open Access Journals (Sweden)

Jose Enrique Irazuzta

Full Text Available Abstract Objectives: To describe the role of intravenous magnesium sulfate (MgSO4 as therapy for acute severe asthma in the pediatric emergency department (ED. Source: Publications were searched in the PubMed and Cochrane databases using the following keywords: magnesium AND asthma AND children AND clinical trial. A total of 53 publications were retrieved using this criteria. References of relevant articles were also screened. The authors included the summary of relevant publications where intravenous magnesium sulfate was studied in children (age <18 years with acute asthma. The NAEPP and Global Initiative for Asthma expert panel guidelines were also reviewed. Summary of the data: There is a large variability in the ED practices on the intravenous administration of MgSO4 for severe asthma. The pharmacokinetics of MgSO4 is often not taken into account with a consequent impact in its pharmacodynamics properties. The cumulative evidence points to the effectiveness of intravenous MgSO4 in preventing hospitalization, if utilized in a timely manner and at an appropriate dosage (50-75 mg/kg. For every five children treated in the ED, one hospital admission could be prevented. Another administration modality is a high-dose continuous magnesium sulfate infusion (HDMI as 50 mg/kg/h/4 h (200 mg/kg/4 h. The early utilization of HDMI for non-infectious mediated asthma may be superior to a MgSO4 bolus in avoiding admissions and expediting discharges from the ED. HDMI appears to be cost-effective if applied early to a selected population. Intravenous MgSO4 has a similar safety profile than other asthma therapies. Conclusions: Treatment with intravenous MgSO4 reduces the odds of hospital admissions. The use of intravenous MgSO4 in the emergency room was not associated with significant side effects or harm. The authors emphasize the role of MgSO4 as an adjunctive therapy, while corticosteroids and beta agonist remain the primary acute therapeutic agents.

A 5-year old female presented with acute tetraparesis and areflexia. Initial imaging and cerebrospinal fluid analysis were suggestive of acute disseminated encephalomyelitis (ADEM). Minimal clinical response with intravenous steroids prompted further work up. Limited nerve conduction studies suggested possible acute motor-sensory axonal neuropathy, a rare variant of Guillain-Barré syndrome (GBS). Repeat imaging was compatible with polyradiculopathy indicating concomitance of ADEM and GBS. The patient suffered severe motor deficits and neuropathic pain. Slow but significant functional recovery was noted after intensive inpatient rehabilitation followed by continued rehabilitation via home health services.

2015-09-01

To summarize recent data on classification systems, cause, risk factors, severity prediction, nutrition, and drug treatment of acute pancreatitis. Comparison of the Revised Atlanta Classification and Determinant Based Classification has shown heterogeneous results. Simvastatin has a protective effect against acute pancreatitis. Young black male, alcohol, smoldering symptoms, and subsequent diagnosis of chronic pancreatitis are risk factors associated with readmissions after acute pancreatitis. A reliable clinical or laboratory marker or a scoring system to predict severity is lacking. The PYTHON trial has shown that oral feeding with on demand nasoenteric tube feeding after 72 h is as good as nasoenteric tube feeding within 24 h in preventing infections in predicted severe acute pancreatitis. Male sex, multiple organ failure, extent of pancreatic necrosis, and heterogeneous collection are factors associated with failure of percutaneous drainage of pancreatic collections. The newly proposed classification systems of acute pancreatitis need to be evaluated more critically. New biomarkers are needed for severity prediction. Further well designed studies are required to assess the type of enteral nutritional formulations for acute pancreatitis. The optimal minimally invasive method or combination to debride the necrotic collections is evolving. There is a great need for a drug to treat the disease early on to prevent morbidity and mortality.

Full Text Available BACKGROUND: Acute endophthalmitis is one of the most serious complications of cataract surgery and often results in severe visual impairment. Several risk factors for acute postoperative endophthalmitis (POE following cataract surgery have been reported but the level of evidence and strength of association is varied. The purpose of this study was to critically appraise published reports on and to summarize clinical risk factors associated with acute POE which could be easily assessed by ophthalmologists for the introduction and implementation of preventive measure. METHODS: A systematic review and meta-analysis of observational studies was performed. Six databases were searched with no limits on the year or language of publication. Study-specific odds ratios (Ors or relative risk (RR of each risk factor were pooled using a random effect model. RESULTS: A total of 6 686 169 participants with 8 963 endophthalmitis in 42 studies were analyzed. Of the nine risk factors identified in our systematic review and meta-analysis, extra- or intracapsular cataract extraction, a clear corneal incision, without intracameral cefazolin (1 mg in 0.1 ml solution, without intracameral cefuroxime (1 mg in 0.1 ml solution, post capsular rupture, silicone intraocular lenses and intraoperative complications were found strongly associated with acute endophthalmitis. Other significant factors with a lower strength of association (risk estimates generally 1.5 or less were male gender and old age (85 years and older. CONCLUSIONS: Our study provides summary data on the risk factors for acute POE. Identifying patients at high risk of this sight-threatening eye disease is important from both the public health and clinical perspectives as this would facilitate detection of disease before the onset of irreversible visual loss enabling earlier intervention.

Antibiotics versus appendectomy in the management of acute appendicitis: a review of the current evidence.

2011-10-01

Acute appendicitis remains the most common cause of the acute abdomen in young adults, and the mainstay of treatment in most centres is an appendectomy. However, treatment for other intra-abdominal inflammatory processes, such as diverticulitis, consists initially of conservative management with antibiotics. The aim of this study was to determine the role of antibiotics in the management of acute appendicitis and to assess if appendectomy remains the gold standard of care. A literature search using MEDLINE and the Cochrane Library identified studies published between 1999 and 2009, and we reviewed all relevant articles. The articles were critiqued using the Public Health Resource Unit (2006) appraisal tools. Our search yielded 41 papers, and we identified a total of 13 papers within the criteria specified. All of these papers, while posing pertinent questions and demonstrating the role of antibiotics as a bridge to surgery, failed to adequately justify their findings that antibiotics could be used as a definitive treatment of acute appendicitis. Appendectomy remains the gold standard of treatment for acute appendicitis based on the current evidence.

To assess the relationship between ambulance attendances, emergency department (ED) presentations and hospital admissions for acute alcohol intoxication and the timing of public holidays, sporting and social events. Time-series analysis was used to explore trends in intoxication in the context of major events. Population of Melbourne, Victoria, Australia between 2000 and 2009. All patients attended by ambulance, presenting to hospital EDs, or admitted to hospital who were classified as acutely alcohol intoxicated. Analysis of daily numbers of presentations for acute alcohol intoxication associated with major events were undertaken, including lead and lag effects. Analyses controlled for day of week and month of year to address temporal and seasonal variations. Alcohol intoxication presentations were significantly elevated the day before all public holidays, with intoxication cases on the day of public holidays only higher on New Year's Day (ambulance 6.57, 95% confidence intervals (CI): 3.4-9.74; ED 3.34, 95% CI: 1.28-5.4) and ANZAC Day (ambulance 3.71, 95% CI: 0.68-6.75). The Australian Football League (AFL) Grand Final (ED 2.37, 95% CI: 0.55-4.19), Commonwealth Games (ED 2.45, 95% CI: 0.6-4.3) and Melbourne Cup Day (ambulance 6.14, 95% CI: 2.42-9.85) represented the sporting events with significant elevations in acute intoxication requiring medical attention. The last working day before Christmas was the only social event where a significant increase in acute intoxication occurred (ambulance 8.98, 95% CI: 6.8-11.15). Acute alcohol intoxication cases requiring ambulance, emergency department and hospital in-patient treatment increase substantially on the day preceding public holidays and other major social events. © 2012 The Authors, Addiction © 2012 Society for the Study of Addiction.

To determine the prevalence of acute symptomatic seizures in infants with supratentorial intracranial hemorrhage, to identify potential risk factors, and to determine the effect of acute seizures on long-term morbidity and mortality. Children less than 24 months with intracranial hemorrhage were identified from a neurocritical care database. All patients who received seizure prophylaxis beginning at admission were included in the study. Risk factors studied were gender, etiology, location of hemorrhage, seizure(s) on presentation, and the presence of parenchymal injury. Acute clinical and electrographic seizures were identified from hospital medical records. Subsequent development of late seizures was determined based on clinical information from patients' latest follow-up. Patients with idiopathic neonatal intracranial hemorrhage, premature infants, and those with prior history of seizures were excluded from analysis. Seventy-two infants met inclusion criteria. None. Forty percent of infants had acute symptomatic seizures. The prevalence was similar regardless of whether etiology of hemorrhage was traumatic or nontraumatic. Seizures on presentation and parenchymal injury were independent risk factors of acute seizures (p = 0.001 and p = 0.006, respectively). Younger children and women were also at higher risk (p Acute seizures were not predictive of mortality, but nearly twice as many patients with acute seizures developed late seizures when compared with those without. Electrographic seizures and parenchymal injury were also predictive of development of late seizures (p hemorrhage are at high risk for acute symptomatic seizures. This is regardless of the etiology of hemorrhage. Younger patients, women, patients with parenchymal injury, and patients presenting with seizure are most likely to develop acute seizures. Although the benefits of seizure prophylaxis have not been studied in this specific population, these results suggest that it is an important component

To study the outcome of acute collections occurring in patients with acute pancreatitis BACKGROUND:: There are limited data on natural history of acute collections arising after acute pancreatitis (AP). Consecutive patients of AP admitted between July 2011 and December 2012 were evaluated by imaging for development of acute collections as defined by revised Atlanta classification. Imaging was repeated at 1 and 3 months. Spontaneous resolution, evolution, and need for intervention were assessed. Of the 189 patients, 151 patients (79.9%) had acute collections with severe disease and delayed hospitalization being predictors of acute collections. Thirty-six patients had acute interstitial edematous pancreatitis, 8 of whom developed acute peripancreatic fluid collections, of which 1 evolved into pseudocyst. Among the 153 patients with acute necrotizing pancreatitis, 143 (93.4%) developed acute necrotic collection (ANC). Twenty-three of 143 ANC patients died, 21 had resolved collections, whereas 84 developed walled-off necrosis (WON), with necrosis >30% (P = 0.010) and Computed Tomographic Severity Index score ≥7 (P = 0.048) predicting development of WON. Of the 84 patients with WON, 8 expired, 53 patients required an intervention, and 23 were managed conservatively. Independent predictors of any intervention among all patients were Computed Tomographic Severity Index score ≥7 (P 7 days (P = 0.04). Patients with severe AP and delayed hospitalization more often develop acute collections. Pancreatic pseudocysts are a rarity in acute interstitial pancreatitis. A majority of patients with necrotising pancreatitis will develop ANC, more than half of whom will develop WON. Delay in hospitalization and higher baseline necrosis score predict need for intervention.

Full Text Available Chikungunya virus (CHIKV re-emerged in Sri Lanka in late 2006 after a 40-year hiatus. We sought to identify and characterize acute chikungunya infection (CHIK in patients presenting with acute undifferentiated febrile illness in unstudied rural and semi-urban southern Sri Lanka in 2007.We enrolled febrile patients ≥ 2 years of age, collected uniform epidemiologic and clinical data, and obtained serum samples for serology, virus isolation, and real-time reverse-transcriptase PCR (RT-PCR. Serology on paired acute and convalescent samples identified acute chikungunya infection in 3.5% (28/797 patients without acute dengue virus (DENV infection, 64.3% (18/28 of which were confirmed by viral isolation and/or real-time RT-PCR. No CHIKV/DENV co-infections were detected among 54 patients with confirmed acute DENV. Sequencing of the E1 coding region of six temporally distinct CHIKV isolates (April through October 2007 showed that all isolates posessed the E1-226A residue and were most closely related to Sri Lankan and Indian isolates from the same time period. Except for more frequent and persistent musculoskeletal symptoms, acute chikungunya infections mimicked DENV and other acute febrile illnesses. Only 12/797 (1.5% patients had serological evidence of past chikungunya infection.Our findings suggest CHIKV is a prominent cause of non-specific acute febrile illness in southern Sri Lanka.

Vergel, Juliana; Tamayo-Orozco, Sebastián; Vallejo-Gómez, Andrés Felipe; Posada, María Teresa; Restrepo, Diana

Stress has been associated with an acute heart failure syndrome of important morbidity and mortality. Case report and non-systematic review of the relevant literature. A 65-year-old woman with a history of an untreated generalized anxiety disorder, whom after the violent death of her son presented with oppressive chest pain irradiated to neck and left superior extremity, lasting for more than 30minutes, initial clinical suspect suggests acute coronary syndrome. Tako-tsubo cardiomyopathy is characterized by a reversible left ventricular dysfunction and wall movement abnormalities, without any compromise of the coronary arteries, associated to high plasma levels of catecholamines which in most cases correlates with an acute stress of emotional or physical type. Tako-tsubo cardiomyopathy has to be considered by physicians among the differential diagnosis when facing a patient with suspected acute coronary syndrome, especially in post-menopausal women with a history of psychiatric comorbidities such as a generalized anxiety disorder.

Bhate, Sanjay; Ganesan, Vijeya

2015-08-01

Acute hemiparesis in children is a common clinical syndrome presenting to a variety of care settings. The recognition and the differential diagnosis is challenging, particularly in young children. Arterial ischaemic stroke (AIS) is the primary diagnosis to be considered as this requires emergency investigations and management; however, there are several conditions collectively described as 'stroke mimics' that need consideration. Accurate diagnosis is essential for appropriate management. Clinical data combined with neuroimaging are important for accurate diagnosis and management. This review and the accompanying illustrative case vignettes suggest a practical approach to differential diagnosis and management of children presenting with acute hemiparesis. © 2015 Mac Keith Press.

Public Debt, Public Investment and Economic Growth in Mexico

Directory of Open Access Journals (Sweden)

Isaac Sánchez-Juárez

2016-03-01

Full Text Available The primary objective of this article is to answer the following two research questions: has the growing public debt of state governments promoted increased public investment? If the answer is yes, then does any increase in public investment lead to more growth in the Mexican states? Dynamic Models of panel data and the Generalized Method of Moments, with information for 32 states from 1993 to 2012, were used for this purpose. The econometric results confirmed that public debt is positively correlated with public investment and that this in turn generates economic growth. This does not mean that a good economic policy strategy has been followed, since the marginal positive impact of public investment, and therefore the public debt on the production per person, is reduced (1% increase in the interaction between public investment and public debt variable causes a 0.0005% increase in economic growth. This suggests deviations from the debt contracted for purposes other than production, which could lead to a situation of unsustainability of state public finances in the medium term.

Noradrenaline and dopamine levels in acute cerveau isolé in the cat.

Szikszay, M; Benedek, G; Obál, F; Obál, F

1980-01-01

Noradrenaline (NA) and dopamine (DA) levels were studied in the forebrain of acute immobilized cats and in cerveau isolé preparations. A gradual decrease in NA and DA was observed one and two hours after high mesencephalic transection, while the amount of NA increased in acute immobilized cats after the cessation of ether anaesthesia. These changes in NA level are consistent with the observations suggesting an inverse relationship between NA and cortical deactivation. The decrease of DA with an exaggeration of spindle activity and increased synchronizing effect of basal forebrain stimulation indicate that the spindle-increasing effect of DA suggested by several authors requires the contribution of the brain stem.

Objective. Pain is defined as an unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage. Current pain research mostly focuses on molecular and synaptic changes at the spinal and peripheral levels. However, a complete understanding of pain mechanisms requires the physiological study of the neocortex. Our goal is to apply a neural decoding approach to read out the onset of acute thermal pain signals, which can be used for brain-machine interface. Approach. We used micro wire arrays to record ensemble neuronal activities from the primary somatosensory cortex (S1) and anterior cingulate cortex (ACC) in freely behaving rats. We further investigated neural codes for acute thermal pain at both single-cell and population levels. To detect the onset of acute thermal pain signals, we developed a novel latent state-space framework to decipher the sorted or unsorted S1 and ACC ensemble spike activities, which reveal information about the onset of pain signals. Main results. The state space analysis allows us to uncover a latent state process that drives the observed ensemble spike activity, and to further detect the ‘neuronal threshold’ for acute thermal pain on a single-trial basis. Our method achieved good detection performance in sensitivity and specificity. In addition, our results suggested that an optimal strategy for detecting the onset of acute thermal pain signals may be based on combined evidence from S1 and ACC population codes. Significance. Our study is the first to detect the onset of acute pain signals based on neuronal ensemble spike activity. It is important from a mechanistic viewpoint as it relates to the significance of S1 and ACC activities in the regulation of the acute pain onset.

The role of parvovirus B19 and the immune response in the pathogenesis of acute leukemia.

Science.gov (United States)

Kerr, Jonathan R; Mattey, Derek L

2015-05-01

In this article, we review the evidence suggesting a possible role for B19 virus in the pathogenesis of a subset of cases of acute leukemia. Human parvovirus B19 infection may complicate the clinical course of patients with acute leukemia and may also precede the development of acute leukemia by up to 180 days. Parvovirus B19 targets erythroblasts in the bone marrow and may cause aplastic crisis in patients with shortened-red cell survival. Aplastic crisis represents a prodrome of acute lymphoblastic leukemia in 2% patients. There is a significant overlap between those HLA classes I and II alleles that are associated with a vigorous immune response and development of symptoms during B19 infection and those HLA alleles that predispose to development of acute leukemia. Acute symptomatic B19 infection is associated with low circulating IL-10 consistent with a vigorous immune response; deficient IL-10 production at birth was recently found to be associated with subsequent development of acute leukemia. Anti-B19 IgG has been associated with a particular profile of methylation of human cancer genes in patients with acute leukemia, suggesting an additional hit and run mechanism. The proposed role for parvovirus B19 in the pathogenesis of acute leukemia fits well with the delayed infection hypothesis and with the two-step mutation model, which describes carriage of the first mutation prior to birth, followed by suppression of hematopoiesis, which allows rapid proliferation of cells harboring the first mutation, acquisition of a second activating mutation, and expansion of cells carrying both mutations, resulting in acute leukemia.

Raha, Sarbani; Udani, Vrajesh

2012-12-01

Acute Infantile Encephalopathy Predominantly Affecting the Frontal Lobes (AIEF) is a relatively recent described entity. This article includes case reports of two patients who had bifrontal involvement during acute febrile encephalopathy. Case 1 describes a 1-y-old boy who presented with hyperpyrexia and dialeptic seizures. Imaging revealed significant bilateral frontal lobe involvement while serology proved presence of Influenza B infection. Over a period of one wk, he recovered with significant cognitive decline and perseveratory behavior. Another 6-y-old boy presented with language and behavioral problems suggestive of frontal dysfunction after recovering from prolonged impairment of consciousness following a convulsive status epilepticus. Bilateral superior frontal lesions with gyral swelling was evident on neuroimaging. These cases are among the very few cases of AIEF described in recent literature and the article also reviews this unique subtype of acute encephalopathy.

Murine models have suggested that CD8+ T-cell responses peak early in acute viral infections and are not sustained, but no evidence for humans has been available. To address this, we longitudinally analyzed the CD8+ T-cell response to human parvovirus B19 in acutely infected individuals. We...... observed striking CD8+ T-cell responses, which were sustained or even increased over many months after the resolution of acute disease, indicating that CD8+ T cells may play a prominent role in the control of parvovirus B19 and other acute viral infections of humans, including potentially those generated...

The axonal guidance receptor neogenin promotes acute inflammation.

Directory of Open Access Journals (Sweden)

Klemens König

Full Text Available Neuronal guidance proteins (NGP were originally described in the context of axonal growth and migration. Yet recent work has demonstrated that NGPs also serve as guidance cues for immune competent cells. A crucial target receptor for NGPs during embryonic development is the neogenin receptor, however its role during acute inflammation is unknown. We report here that neogenin is abundantly expressed outside the nervous system and that animals with endogenous repression of neogenin (Neo1(-/- demonstrate attenuated changes of acute inflammation. Studies using functional inhibition of neogenin resulted in a significant attenuation of inflammatory peritonitis. In studies employing bone marrow chimeric animals we found the hematopoietic presence of Neo1(-/- to be responsible for the attenuated inflammatory response. Taken together our studies suggest that the guidance receptor neogenin holds crucial importance for the propagation of an acute inflammatory response and further define mechanisms shared between the nervous and the immune system.

Principles and practical procedures for acute psychological first aid training for personnel without mental health experience.

Everly, George S; Flynn, Brian W

2006-01-01

Most authorities agree that mass disasters leave in their wake a need for some form of acute mental health services. However, a review of current literature on crisis intervention and disaster mental health reveals differing points of view on the methods that should be employed (Raphael, 1986; NIMH, 2002). Nevertheless, there appears to be virtual universal endorsement, by relevant authorities, of the value of acute "psychological first aid" (American Psychiatric Association, 1954; USDHHS, 2004; Raphael, 1986; NIMH, 2002; Institute of Medicine, 2003; WHO, 2003; DoD/VAPTSD, 2004; Ritchie, et al., 2004; Friedman, Hamblin, Foa, & Charney, 2004). Psychological first aid (PFA), as an acute mental health intervention, seems uniquely applicable to public health settings, the workplace, the military, mass disaster venues, and even the demands of more well circumscribed critical incidents, e.g., dealing with the psychological aftermath of accidents, robberies, suicide, homicide, or community violence. In this document, we shall introduce the notion of psychological first aid (PFA) as one aspect of a psychological continuum of care, offer a rudimentary definition of PFA, and provide the reader with a practicalframework for its implementation utilizing the individual psychological first aid (iPFA)format. The goal of this paper is to better prepare public health, public safety, and other disaster response personnel who do not possess formal clinical mental health degrees or specialized training to provide iPFA services to primary and secondary disaster victims.

Cannabidiol Rescues Acute Hepatic Toxicity and Seizure Induced by Cocaine

Directory of Open Access Journals (Sweden)

Luciano Rezende Vilela

2015-01-01

Full Text Available Cocaine is a commonly abused illicit drug that causes significant morbidity and mortality. The most severe and common complications are seizures, ischemic strokes, myocardial infarction, and acute liver injury. Here, we demonstrated that acute cocaine intoxication promoted seizure along with acute liver damage in mice, with intense inflammatory infiltrate. Considering the protective role of the endocannabinoid system against cell toxicity, we hypothesized that treatment with an anandamide hydrolysis inhibitor, URB597, or with a phytocannabinoid, cannabidiol (CBD, protects against cocaine toxicity. URB597 (1.0 mg/kg abolished cocaine-induced seizure, yet it did not protect against acute liver injury. Using confocal liver intravital microscopy, we observed that CBD (30 mg/kg reduced acute liver inflammation and damage induced by cocaine and prevented associated seizure. Additionally, we showed that previous liver damage induced by another hepatotoxic drug (acetaminophen increased seizure and lethality induced by cocaine intoxication, linking hepatotoxicity to seizure dynamics. These findings suggest that activation of cannabinoid system may have protective actions on both liver and brain induced by cocaine, minimizing inflammatory injury promoted by cocaine, supporting its further clinical application in the treatment of cocaine abuse.

Prolactin (PRL), a hormone produced by the pituitary gland, has multiple physiological functions, including immunoregulation. PRL can also be secreted in response to stressful stimuli. During stress, PRL has been suggested to oppose the immunosuppressive effects of inflammatory mediators. Therefore, the aim of the present study was to analyze the effects of short- and long-term hyperprolactinemia on the inflammatory response in rats subjected to acute or chronic cold stress. Inflammatory edema was induced by carrageenan in male rats, and hyperprolactinemia was induced by injections of the dopamine receptor antagonist domperidone. The volume of inflammatory edema was measured by plethysmography after carrageenan injection. Additionally, the effects of hyperprolactinemia on body weight and serum corticosterone levels were evaluated. Five days of domperidone-induced hyperprolactinemia increased the volume of inflammatory edema. No differences in serum corticosterone levels were observed between groups. No significant differences were found among 30 days domperidone-induced hyperprolactinemic animals subjected to acute stress and the inflammatory response observed in chronic hyperprolactinemic animals subjected to chronic stress. The results suggest that short-term hyperprolactinemia has pro-inflammatory effects. Because such an effect was not observed in long-term hyperprolactinemic animals, PRL-induced tolerance seems likely. We suggest that short-term hyperprolactinemia may act as a protective factor in rats subjected to acute stress. These data suggest that hyperprolactinemia and stress interact differentially according to the time period. Copyright 2010 S. Karger AG, Basel.

Auckland City Hospital is one of the largest metropolitan public hospitals in New Zealand where more than 60 % of surgical admissions fit into the acute category. In January 2009, an Acute Surgical Unit (ASU) was set up to improve acute surgical flow. Key performance indicators (KPIs) were identified as valuable tools in evaluating ASU service performance. Our goals were to describe the current acute patient pathway, present the early trend of KPIs for the ASU and determine whether an impact has been made on acute surgical patients. A retrospective review of patients admitted with acute general surgical conditions from January 2008 (pre-ASU) to October 2010 was performed. Patient data were identified through hospital electronic records. KPIs assessed included: (1) time to assess referred patients from the emergency department (ED) and from GPs [where patient assessment occurs in the assessment and planning unit (APU)]; (2) preoperative length of stay (LOS[PO]); (3) length of stay of nonadmitted patients (LOS[NA]); (4) case volume "in h" (0730-1730) versus "after h"; and (5) readmission rate. Statistical analysis was performed with one-way ANOVA, regression, and χ(2) tests. Results show a reduction of mean time from referral to assessment from 2.28 to 1.6 h in the ED (p ≤ 0.001). Patients are seen in APU after GP referral sooner as well as the time from referral to assessment reducing from 2 to 1.76 h (p < 0.001). The LOS[PO] has not changed significantly overall (34.58 vs. 34.88 h, p = not significant [NS]). However, there are encouraging signs in high-volume procedures, such as appendicectomy. The mean LOS[PO] for appendicectomy was 7.81 h but is now 6.53 h (p ≤ 0.005). The LOS[NA] has decreased from 15.23 to 9.48 h (p < 0.005). Since the development of the ASU, the number of cases operated on "in hours" is increasing with a corresponding decrease in "after hours

Acute kidney injury: Global health alert

Full Text Available Acute kidney injury (AKI is increasingly prevalent in developing and developed countries and is associated with severe morbidity and mortality. Most etiologies of AKI can be prevented by interventions at the individual, community, regional and in-hospital levels. Effective measures must include community-wide efforts to increase an awareness of the devastating effects of AKI and provide guidance on preventive strategies, as well as early recognition and management. Efforts should be focused on minimizing causes of AKI, increasing awareness of the importance of serial measurements of serum creatinine in high risk patients, and documenting urine volume in acutely ill people to achieve early diagnosis; there is as yet no definitive role for alternative biomarkers. Protocols need to be developed to systematically manage prerenal conditions and specific infections. More accurate data about the true incidence and clinical impact of AKI will help to raise the importance of the disease in the community, increase awareness of AKI by governments, the public, general and family physicians and other health care professionals to help prevent the disease. Prevention is the key to avoid the heavy burden of mortality and morbidity associated with AKI.

Self-esteem and coping strategies have been important factors in athletes' response to injury and subsequent rehabilitation. Specifically, athletic injury has been negatively associated with self-esteem, while certain coping strategies may enhance adherence to rehabilitation (1, 4). Little is known, however, concerning the effect of acute (sudden specific event) versus chronic injury (repetitive injury over a prolonged period of time) on self-esteem and coping strategies. The Rosenberg Self-esteem Inventory (3), selected subscales of the Ways of Coping Questionnaire (2), and a demographic questionnaire were administered. The subscales of Ways of Coping Questionnaire employed were Seeking Social Support, Accepting Responsibility for the injury, and Escape Avoidance of the injury. To assess the influence of acute versus chronic injury status, effect sizes (ES) were calculated. Although no difference was found for Accepting Responsibility, chronically injured athletes scored higher on Escape/Avoidance (M = 2.4 vs 1.9, SD = 1.2 vs .6, ES = .52) and lower on Seeking Social Support (M = 2.5 vs 2.8, SD = .6 vs .4, ES = .47) than athletes with acute injuries. Those with chronic injuries also second more negatively on self-esteem (M = 6.2 vs 4.4, SD = 1.2 vs 1.2, ES = 1.30) than acutely injured athletes. These preliminary results suggest the type of injury may differentially affect self-esteem and coping behavior. As self-esteem is theorized to be relatively stable construct, it is perhaps not surprising that chronic injuries have a greater effect than acute injuries. Chronically injured athletes also sought social support less and engaged in more escape/avoidance behavior, suggesting that they cope with injury differently than those with acute injuries.

Acute otitis media associated bilateral sudden hearing loss: case report and literature review.

2017-07-01

Sudden sensorineural hearing loss is a rare otological condition with potential for dire outcomes including permanent hearing loss. Although the majority of cases are deemed idiopathic, bilateral sudden sensorineural hearing loss represents a rare subset typically related to systemic conditions, with higher morbidity and mortality. A controversial association with acute otitis media has been reported, with few bilateral cases published in the literature. A very rare case of bilateral sudden sensorineural hearing loss associated with acute otitis media is described, with a review of the literature. The limited evidence available suggests that acute otitis media with tinnitus and/or bacterial pathology may have an increased risk of sudden sensorineural hearing loss, which is consistent with the case described. Although there is no sufficiently powered published evidence to provide definitive treatment guidelines, the literature reviewed suggests that early myringotomy and antibiotics may greatly improve treatment outcomes.

Hypnosis, suggestion, and suggestibility: an integrative model.

Lynn, Steven Jay; Laurence, Jean-Roch; Kirsch, Irving

2015-01-01

This article elucidates an integrative model of hypnosis that integrates social, cultural, cognitive, and neurophysiological variables at play both in and out of hypnosis and considers their dynamic interaction as determinants of the multifaceted experience of hypnosis. The roles of these variables are examined in the induction and suggestion stages of hypnosis, including how they are related to the experience of involuntariness, one of the hallmarks of hypnosis. It is suggested that studies of the modification of hypnotic suggestibility; cognitive flexibility; response sets and expectancies; the default-mode network; and the search for the neurophysiological correlates of hypnosis, more broadly, in conjunction with research on social psychological variables, hold much promise to further understanding of hypnosis.

Transfusion related acute lung injury presenting with acute dyspnoea: a case report

Full Text Available Abstract Introduction Transfusion-related acute lung injury is emerging as a common cause of transfusion-related adverse events. However, awareness about this entity in the medical fraternity is low and it, consequently, remains a very under-reported and often an under-diagnosed complication of transfusion therapy. Case presentation We report a case of a 46-year old woman who developed acute respiratory and hemodynamic instability following a single unit blood transfusion in the postoperative period. Investigation results were non-specific and a diagnosis of transfusion-related acute lung injury was made after excluding other possible causes of acute lung injury. She responded to symptomatic management with ventilatory and vasopressor support and recovered completely over the next 72 hours. Conclusion The diagnosis of transfusion-related acute lung injury relies on excluding other causes of acute pulmonary edema following transfusion, such as sepsis, volume overload, and cardiogenic pulmonary edema. All plasma containing blood products have been implicated in transfusion-related acute lung injury, with the majority being linked to whole blood, packed red blood cells, platelets, and fresh-frozen plasma. The pathogenesis of transfusion-related acute lung injury may be explained by a "two-hit" hypothesis, involving priming of the inflammatory machinery and then activation of this primed mechanism. Treatment is supportive, with prognosis being substantially better than for most other causes of acute lung injury.

[Acute heart failure: acute cardiogenic pulmonary edema and cardiogenic shock].

Sánchez Marteles, Marta; Urrutia, Agustín

2014-03-01

Acute cardiogenic pulmonary edema and cardiogenic shock are two of the main forms of presentation of acute heart failure. Both entities are serious, with high mortality, and require early diagnosis and prompt and aggressive management. Acute pulmonary edema is due to the passage of fluid through the alveolarcapillary membrane and is usually the result of an acute cardiac episode. Correct evaluation and clinical identification of the process is essential in the management of acute pulmonary edema. The initial aim of treatment is to ensure hemodynamic stability and to correct hypoxemia. Other measures that can be used are vasodilators such as nitroglycerin, loop diuretics and, in specific instances, opioids. Cardiogenic shock is characterized by sustained hypoperfusion, pulmonary wedge pressure > 18 mmHg and a cardiac index 30 mmHg) and absent or reduced diuresis (acute myocardial infarction. Treatment consists of general measures to reverse acidosis and hypoxemia, as well as the use of vasopressors and inotropic drugs. Early coronary revascularization has been demonstrated to improve survival in shock associated with ischaemic heart disease. Copyright © 2014 Elsevier España, S.L. All rights reserved.

Chronic and Acute Relational Risk Factors for Dating Aggression in Adolescence and Young Adulthood.

Science.gov (United States)

Collibee, Charlene; Furman, Wyndol

2016-04-01

Dating aggression is a prevalent and costly public health concern. Using a relational risk framework, this study examined acute and chronic relational risk factors (negative interactions, jealousy, support, and relationship satisfaction) and their effects on physical and psychological dating aggression. The study also examined the interaction between chronic and acute risk, allowing us to assess how changes in acute risk have differing effects depending on whether the individual is typically at higher chronic risk. A sample of 200 youth (100 female) completed seven waves of data, which spanned 9 years from middle adolescence to young adulthood (M age at Wave 1 = 15.83). Using hierarchical linear modeling, analyses revealed both acute (within-person) and chronic (between-person) levels in jealousy, negative interactions, and relationship satisfaction, were associated with physical and psychological dating aggression. Significant interactions between chronic and acute risk emerged in predicting physical aggression for negative interactions, jealousy, and relationship satisfaction such that those with higher levels of chronic risk are more vulnerable to increases in acute risk. These interactions between chronic and acute risk indicate that risk is not static, and dating aggression is particularly likely to occur at certain times for youth at high risk for dating aggression. Such periods of increased risk may provide opportunities for interventions to be particularly effective in preventing dating aggression or its consequences. Taken together, these findings provide support for the role of relational risk factors for dating aggression. They also underscore the importance of considering risk dynamically.

Oxygen in the Setting of Acute Myocardial Infarction: Is It Really a Breath of Fresh Air?

Loomba, Rohit S; Nijhawan, Karan; Aggarwal, Saurabh; Arora, Rohit R

2016-03-01

Supplemental oxygen has been used in the setting of acute myocardial infarction (AMI). Once an official recommendation in the guidelines for the management of acute ST-segment elevation myocardial infarction, it is now mentioned as an intervention to be considered. Data for the use of supplemental oxygen or AMI are limited, and some data have suggested associated harm. We performed a systematic review of the literature and a subsequent meta-analysis of the data to determine the effect of high concentration oxygen versus titrated oxygen or room air in the setting of AMI. The following end points were studied: in-hospital mortality, opiate use, percentage of infarcted myocardium by magnetic resonance imaging (MRI), and mass of infarcted myocardium by MRI. No significant difference was noted with end points when comparing those randomized to high-concentration oxygen versus those randomized to titrated oxygen or room air in the setting of AMI. No significant publication bias was identified although this could not be assessed for all end points. High-concentration oxygen may not offer any benefit when compared to titrated oxygen or room air. A large, randomized trial is warranted to further delineate these differences with respect to multiple end points. © The Author(s) 2015.

The aim of the study was to estimate the preponderance of patterns of pediatric stroke, ischemic or hemorrhagic, their etiologies and the correct diagnostic protocol for acute management. Forty-one consecutive pediatric patients (age range 5-16 years) with an acute stroke observed in acute phase during a 10-year period, were retrospectively evaluated. Twenty-three patients underwent magnetic resonance imaging (MRI), 3 cases were studied by computed tomography (CT) without MRI, and 15 underwent both CT and MRI studies. In 9 cases, intra-arterial digital subtraction angiography (IADSA) was performed after non-invasive preliminary assessment. Seventeen hemorrhagic (41%) and 24 ischemic (59%) strokes were found. Among hemorrhagic forms, 5 cases were due to arteriovenous malformation (AVM), 7 to cavernoma, and 2 to aneurysm. Among ischemic forms, 2 were due to sickle-cell disease, 1 to hyperomocysteinemia, 1 to moyamoya syndrome, 1 to pseudoxantoma elasticum, 3 to prothrombotic state, 1 to Fabry's disease, 1 concomitant with CO intoxication, 5 to venous sinus thrombosis, and 4 to cardio-embolic state. Etiology remains unknown in 8 cases (20.5%). This study shows a moderate prevalence of ischemic over hemorrhagic strokes. Moreover, personal experience suggests that MRI is always more informative than CT and in selected cases should be the first-choice examination in the acute phase.

BET 2: LASER THERAPY IN THE TREATMENT OF ACUTE HAMSTRING MUSCLE INJURIES.

Hughes, Tom; Callaghan, Michael

2017-04-01

Local laser therapy has been suggested as a promising treatment for acute hamstring muscle tears. We carried out a shortcut systematic review to establish whether therapeutic lasers are beneficial for patients with acute hamstring tears. Despite a comprehensive literature search, no studies that were directly relevant to the question could be identified. The clinical bottom line is therefore that there is currently no evidence for the use of any form of laser therapy in the treatment of acute hamstring muscle tears. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

The continuum of spreading depolarizations in acute cortical lesion development

DEFF Research Database (Denmark)

Hartings, Jed A; Shuttleworth, C William; Kirov, Sergei A

2017-01-01

A modern understanding of how cerebral cortical lesions develop after acute brain injury is based on Aristides Leão's historic discoveries of spreading depression and asphyxial/anoxic depolarization. Treated as separate entities for decades, we now appreciate that these events define a continuum....... The causal role of these waves in lesion development has been proven by real-time monitoring of electrophysiology, blood flow, and cytotoxic edema. The spreading depolarization continuum further applies to other models of acute cortical lesions, suggesting that it is a universal principle of cortical lesion...

The supply and distribution of mechanical ventilation capacity is of profound importance for planning for severe public health emergencies. However, the capability of US health systems to provide mechanical ventilation for children and adults remains poorly quantified. The objective of this study was to determine the quantity of adult and pediatric mechanical ventilators at US acute care hospitals. A total of 5,752 US acute care hospitals included in the 2007 American Hospital Association database were surveyed. We measured the quantities of mechanical ventilators and their features. Responding to the survey were 4305 (74.8%) hospitals, which accounted for 83.8% of US intensive care unit beds. Of the 52,118 full-feature mechanical ventilators owned by respondent hospitals, 24,204 (46.4%) are pediatric/neonatal capable. Accounting for nonrespondents, we estimate that there are 62,188 full-feature mechanical ventilators owned by US acute care hospitals. The median number of full-feature mechanical ventilators per 100,000 population for individual states is 19.7 (interquartile ratio 17.2-23.1), ranging from 11.9 to 77.6. The median number of pediatric-capable device full-feature mechanical ventilators per 100,000 population younger than 14 years old is 52.3 (interquartile ratio 43.1-63.9) and the range across states is 22.1 to 206.2. In addition, respondent hospitals reported owning 82,755 ventilators other than full-feature mechanical ventilators; we estimate that there are 98,738 devices other than full-feature ventilators at all of the US acute care hospitals. The number of mechanical ventilators per US population exceeds those reported by other developed countries, but there is wide variation across states in the population-adjusted supply. There are considerably more pediatric-capable ventilators than there are for adults only on a population-adjusted basis.

Full Text Available Introduction. Acute myocardial infarction is life-threatening. A cardiac troponin rise accompanied by typical symptoms, ST elevation or depression is diagnostic of acute myocardial infarction. Here, we report an unusual case of a female who was admitted with chest pain. However, she did not present with a typical profile of an acute myocardial infarction patient. Case Presentation. A 66-year-old Han nationality female presented with chest pain. The electrocardiogram (ECG revealed arched ST segment elevations and troponin was elevated. However, the coronary angiography showed a normal coronary arterial system. Thyroid function tests showed that this patient had severe hyperthyroidism. Conclusion. Our case highlights the possibility that hyperthyroidism may cause a large area of myocardium injury and ECG ST segment elevation. We suggest routine thyroid function testing in patients with chest pain.

Failure to identify an acute exercise effect on executive function assessed by the Wisconsin Card Sorting Test

Conclusion: Acute aerobic exercise failed to influence executive function as assessed by the WCST, revealing that this classical neuropsychological test tapping executive function may not be sensitive to acute exercise. Our findings suggest that acute exercise does not broadly affect the entire family of executive functions, or its effect on a specific aspect of executive function may be task-dependent, as proposed by Etnier and Chang (2009.

Chlamydophila pneumoniae and Mycoplasma pneumoniae are associated with acute exacerbation of bronchial asthma (AEBA). The aim of this study was to evaluate the correlation between these acute bacterial infections and the severity of AEBA. We prospectively analysed consecutive patients admitted to the Emergency Department with acute asthma exacerbation. In every patient peak expiratory flow (PEF) measurement was performed on admission, and spirometry during follow-up. Serology for Chlamydophila and Mycoplasma pneumoniae was performed on admission and after 4-8 weeks. Fifty-eight patients completed the study. Acute atypical infections (AAI) was observed in 22/58 cases; we found single acute C. pneumoniae in 19 cases, single acute M. pneumoniae in 2 cases, and double acute infection in one case. Functional impairment on admission was greater in patients with AAI than in patients without AAI (PEF 205 +/- 104 L/min vs 276 +/- 117 p = 0.02) and persisted until visit 2 (FEV1% 76.30 +/- 24.54 vs FEV1% 92.91 +/- 13.89, p = 0.002). Moreover, the proportion of patients who presented with severe AEBA was significantly greater in the group with AAI than in the group without AAI (15/22 vs 12/36, p = 0.01; OR 4.29, 95% CI 1.38-13.32). Our data suggest an association between acute atypical infection and a more severe AEBA.

Linehan, Kathryn

2012-12-07

Medicare spending on post-acute care provided by skilled nursing facility providers, home health providers, inpatient rehabilitation facility providers, and long-term care hospitals has grown rapidly in the past several years. The Medicare Payment Advisory Commission and others have noted several long-standing problems with the payment systems for post-acute care and have suggested refinements to Medicare's post-acute care payment systems that are intended to encourage the delivery of appropriate care in the right setting for a patient's condition. The Patient Protection and Affordable Care Act of 2010 contained several provisions that affect the Medicare program's post-acute care payment systems and also includes broader payment reforms, such as bundled payment models. This issue brief describes Medicare's payment systems for post-acute care providers, evidence of problems that have been identified with the payment systems, and policies that have been proposed or enacted to remedy those problems.

Mental health in prisons: A public health agenda.

Science.gov (United States)

Fraser, A

2009-01-01

Mental illness affects the majority of prisoners. Mental health issues are beginning to take a central position in the development of prison health services, reflecting this burden of disease. This change in focus is not before time. But prison mental health services cannot exist in isolation. Public health systems should lead provision of care for patients with acute and severe illness. A whole prison approach to health and, specifically, mental health will offer the greatest likelihood that offenders will thrive, benefit from imprisonment, and lead law-abiding lives after release. Public awareness of the scale and commitment of prisons to mental health and illness, and understanding of prisons' role in society, are necessary developments that would protect and enhance public mental health, as well as creating a healthier and safer society. This article draws on recent reviews, information and statements to set out a public health agenda for mental health in prisons.

Acute GI obstruction.

Science.gov (United States)

Hucl, Tomas

2013-10-01

Acute gastrointestinal obstruction occurs when the normal flow of intestinal contents is interrupted. The blockage can occur at any level throughout the gastrointestinal tract. The clinical symptoms depend on the level and extent of obstruction. Various benign and malignant processes can produce acute gastrointestinal obstruction, which often represents a medical emergency because of the potential for bowel ischemia leading to perforation and peritonitis. Early recognition and appropriate treatment are thus essential. The typical clinical symptoms associated with obstruction include nausea, vomiting, dysphagia, abdominal pain and failure to pass bowel movements. Abdominal distention, tympany due to an air-filled stomach and high-pitched bowel sounds suggest the diagnosis. The diagnostic process involves imaging including radiography, ultrasonography, contrast fluoroscopy and computer tomography in less certain cases. In patients with uncomplicated obstruction, management is conservative, including fluid resuscitation, electrolyte replacement, intestinal decompression and bowel rest. In many cases, endoscopy may aid in both the diagnostic process and in therapy. Endoscopy can be used for bowel decompression, dilation of strictures or placement of self-expandable metal stents to restore the luminal flow either as a final treatment or to allow for a delay until elective surgical therapy. When gastrointestinal obstruction results in ischemia, perforation or peritonitis, emergency surgery is required. Copyright © 2013. Published by Elsevier Ltd.

Assessments were conducted 30, 60, 90, and 120 minutes and 24 hours after the first injection for PANSS-EC and ACES, and 2, 4, 6, and 24 hours for CGI. Response was at least a 40% decrease in PANSS-EC scores. We measured serum aripiprazole and dehydroaripiprazole levels in a subsample. IM aripiprazole significantly improved clinical measures. PANSS-EC improved progressively, starting after 30 minutes. ACES improved after 90 minutes and continued thereafter. Effects were sustained, with steadily decreasing CGI scores, until the 24th hour. Response rate was 83.6% after 2 hours, but with repeat injections, it rose to over 90% with no differences among diagnostic groups. Although there were gender differences in the response to individual PANSS-EC items, the responses were similar overall. Neither clinical monitoring nor patient reporting revealed any side effects. No therapeutic window was identified, and levels did not correlate with any clinical measure. Aripiprazole was effective and safe in reducing acute agitation in patients with bipolar disorder or schizophrenia. Our results compare favorably to double-blind trials, probably

Acute gastrointestinal illness is an important public-health issue worldwide. Burden-of-illness studies have not previously been conducted in Cuba. The objective of the study was to determine the magnitude, distribution, and burden of self-reported acute gastrointestinal illness in Cuba. A retrospective, cross-sectional survey was conducted in three sentinel sites during June-July 2005 (rainy season) and during November 2005–January 2006 (dry season). Households were randomly selected from a list maintained by the medical offices in each site. One individual per household was selected to complete a questionnaire in a face-to-face interview. The case definition was three or more bouts of loose stools in a 24-hour period within the last 30 days. In total, 97.3% of 6,576 interviews were completed. The overall prevalence of acute gastrointestinal illness was 10.6%. The risk of acute gastrointestinal illness was higher during the rainy season (odds ratio [OR]=3.85, 95% confidence interval [CI] 3.18-4.66) in children (OR=3.12, 95% CI 2.24-4.36) and teens (OR=2.27, 95% CI 1.51-3.41) compared to people aged 25-54 years, in males (OR=1.24, 95% CI 1.04-1.47), and in the municipality of Santiago de Cuba (OR=1.33, 95% CI 1.11-1.61). Of 680 cases, 17.1-38.1% visited a physician, depending on sentinel site. Of the cases who visited a physician, 33.3-53.9% were requested to submit a stool sample, and of those, 72.7-100.0% complied. Of the cases who sought medical care, 16.7- 61.5% and 0-31.6% were treated with antidiarrhoeals and antibiotics respectively. Acute gastrointestinal illness represented a substantial burden of health compared to developed countries. Targeting the identified risk factors when allocating resources for education, food safety, and infrastructure might lower the morbidity associated with acute gastrointestinal illness. PMID:19507750

Patent foramen ovale (PFO) is an established risk factor for ischemic stroke. Since acute right ventricular dysfunction (RVD) observed in patients with PE can lead to right-to-left inter-atrial shunt via PFO, we hypothesized that PFO is a risk factor for ischemic stroke in PE with significant right ventricular dysfunction. 55 patients (31 F, 24M), median age 49 years (range 19-83 years) with confirmed PE underwent echocardiography for RVD and PFO assessment. High risk acute PE was diagnosed in 3 (5.5%) patients, while 16 (29%) hemodynamically stable with RVD patients formed a group with intermediate-risk PE. PFO was diagnosed in 19 patients (34.5%). Diffusion-weighted MRI of the brain for acute ischemic stroke (AIS) was performed in all patients 4.91 ± 4.1 days after admission. AIS was detected by MRI in 4 patients (7.3%). Only one stroke was clinically overt and resulted in hemiplegia. All 4 AIS occurred in the PFO positive group (4 of 19 patients), and none in subjects without PFO (21.0% vs 0%, p=0.02). Moreover, all AIS occurred in patients with RVD and PFO, and none in patients with PFO without RVD (50% vs 0%, p=0.038). Our data suggest that acute pulmonary embolism resulting in right ventricular dysfunction may lead to acute ischemic stroke in patients with patent foramen ovale. However, the clinical significance of such lesions remains to be determined. Copyright © 2014 Elsevier Ltd. All rights reserved.

To evaluate the clinical picture and microbiological findings of children hospitalized due to acute otitis media and to analyze how it differs from acute mastoiditis. A retrospective review of the medical records of all children (0-16 years) hospitalized due to acute otitis media in the Department of Otorhinolaryngology at the Helsinki University Hospital, between 2003 and 2012. Comparison with previously published data of children with acute mastoiditis (n=56) from the same institute and period of time. The most common pathogens in the children hospitalized due to acute otitis media (n=44) were Streptococcus pneumoniae (18%), Pseudomonas aeruginosa (16%), Streptococcus pyogenes (14%), and Staphylococcus aureus (14%). One of the most common pathogens of out-patient acute otitis media, Haemophilus influenzae, was absent. Otorrhea was common in infections caused by S. pyogenes and otorrhea via tympanostomy tube in infections caused by P. aeruginosa. In children under 2 years-of-age, the most common pathogens were S. pneumoniae (43%), Moraxella catarrhalis (14%), and S. aureus (7%). S. pyogenes and P. aeruginosa were only found in children over 2 years-of-age. Previous health problems, bilateral infections, and facial nerve paresis were more common in children hospitalized due to acute otitis media, compared with acute mastoiditis, but they also demonstrated lower CRP values and shorter duration of hospital stay. The number of performed tympanostomies and mastoidectomies was also comparatively smaller in the children hospitalized due to acute otitis media. S. aureus was more common and S. pneumoniae, especially its resistant strains, was less common in the children hospitalized due to acute otitis media than acute mastoiditis. Acute otitis media requiring hospitalization and acute mastoiditis compose a continuum of complicated acute otitis media that differs from common out-patient acute otitis media.

Full Text Available Acute pancreatitis is a rare life-threatening complication in patients after kidney transplantation. Here we described a 56-year-old man who had received a living related kidney transplant for an end-stage renal disease. In his regular follow-up, his serum creatinine was gradually increased and he underwent an allograft biopsy, which revealed an interstitial nephritis/tubular atrophy grade II. Mycophenolate mofetil (MMF was prescribed to control chronic allograft nephropathy. He presented with complaints of severe abdominal pain, vomiting, loss of appetite and fever requiring hospital admission twelve days later. Acute pancreatitis was diagnosed on the basis of laboratory data and imaging findings during hospital admission. There was no history of alcohol consumption in our patient. Unfortunately he died one week later and autopsy findings demonstrated acute necrotizing pancreatitis. The bladder drainage of this patients was normal. Laboratory findings in this patient did not endorse infections and other possibilities regarding the etiology of acute pancreatitis in this patient. Therefore, we concluded that acute pancreatitis in near the patient was induced by drugs and basis on our evidence, MMF is the most important suspect. This study suggests that acute pancreatitis can be considered as a side effect of MMF.

Chromosomal rearrangements of the human MLL/KMT2A gene are associated with infant, pediatric, adult and therapy-induced acute leukemias. Here we present the data obtained from 2345 acute leukemia patients. Genomic breakpoints within the MLL gene and the involved translocation partner genes (TPGs) were determined and 11 novel TPGs were identified. Thus, a total of 135 different MLL rearrangements have been identified so far, of which 94 TPGs are now characterized at the molecular level. In all, 35 out of these 94 TPGs occur recurrently, but only 9 specific gene fusions account for more than 90% of all illegitimate recombinations of the MLL gene. We observed an age-dependent breakpoint shift with breakpoints localizing within MLL intron 11 associated with acute lymphoblastic leukemia and younger patients, while breakpoints in MLL intron 9 predominate in AML or older patients. The molecular characterization of MLL breakpoints suggests different etiologies in the different age groups and allows the correlation of functional domains of the MLL gene with clinical outcome. This study provides a comprehensive analysis of the MLL recombinome in acute leukemia and demonstrates that the establishment of patient-specific chromosomal fusion sites allows the design of specific PCR primers for minimal residual disease analyses for all patients.

Full Text Available The Canadian Collaborative Acute Pain Initiative, established in 2002, is a voluntary, multidisciplinary consortium of acute pain health professionals from across Canada whose goal is to improve acute pain management through discussion and consensus. The group met in January 2002 to define strategic areas related to the treatment of acute pain. The areas identified were: the definition of pain; the epidemiology of pain; the concept of an 'ideal' acute pain management service; education; therapeutic options; symptom management; and research and safety. In November 2002, a second meeting was held to develop objectives and recommendations for the management of acute pain based on the defined areas. The outcome of these discussions is summarized in this paper.

Hydatidosis as a cause of acute appendicitis: a case report

Directory of Open Access Journals (Sweden)

Maryam Hajizadeh

2013-02-01

Full Text Available Acute appendicitis is considered the most common cause of emergency surgery in children and young adults. The association between parasitic infections and appendicitis has been widely investigated. Hydatidosis, a zoonotic helminthic disease caused by the larval stage of the Echinococcus granulosus, may cause illness in intermediate hosts, generally human and herbivorous animals. This disease is considered hyper endemic in northwest of Iran and is a serious public health problem. Hydatidosis predominantly is located in internal organs especially liver and lung but is considered a rare cause of acute appendicitis. Our aim was to study hydatid cyst that causes appendicitis. In this retrospective descriptive, 275 appendectomies performed during the years 2007-2012 in Tabriz Emam Reza hospital. Depending on the clinical notes, serological method, laboratory, surgical findings and attention to the histopathologic results, we found a patient with appendiceal hydatidosis. Acute appendicitis of hydatidosis origin is not seen frequently even in the hyper endemic area. Therefore, described an unusual cases of hydatidosis, should be considered in the differential diagnoses of appendicitis also education on how to prevent hydatidosis and eradication of stray dogs should be included in training programs to avoid and decrease the appendectomy operations.

Public confidence in nuclear regulator has been discussed internationally. Public trust or confidence is needed for achieving regulatory goal of assuring nuclear safety to the level that is acceptable by the public or providing public ease for nuclear safety. In Korea, public ease or public confidence has been suggested as major policy goal in the 'Nuclear regulatory policy direction' annually announced. This paper reviews theory of trust, its definitions and defines nuclear safety regulation, elements of public trust or public confidence developed based on the study conducted so far. Public ease model developed and 10 measures for ensuring public confidence are also presented and future study directions are suggested

Improving performance management for delivering appropriate care for patients no longer needing acute hospital care.

Penney, Christine; Henry, Effie

2008-01-01

The public, providers and policy-makers are interested in a service continuum where care is provided in the appropriate place. Alternate level of care is used to define patients who no longer need acute care but remain in an acute care bed. Our aims were to determine how subacute care and convalescent care should be defined in British Columbia (BC); how these care levels should be aligned with existing legislation to provide more consistent service standards to patients and what reporting requirements were needed for system planning and performance management. A literature review was conducted to understand the international trends in performance management, care delivery models and change management. A Canada-wide survey was carried out to determine the directions of other provinces on the defined issues and a BC survey provided a current state analysis of programming within the five regional health authorities (HAs). A provincial policy framework for subacute and convalescent care has been developed to begin to address the concerns raised and provide a base for performance measurement. The policy has been approved and disseminated to BC HAs for implementation. An implementation plan has been developed and implementation activities have been integrated into the work of existing provincial committees. Evaluation will occur through performance measurement. The benefits anticipated include: clear policy guidance for programme development; improved comparability of performance information for system monitoring, planning and integrity of the national acute care Discharge Abstracting Database; improved efficiency in acute care bed use; and improved equity of access, insurability and quality for patients requiring subacute and convalescent care. While a national reporting system exists for acute care in Canada, this project raises questions about the implications for this system, given the shifting definition of acute care as other care levels emerge.

The outcome of childhood acute lymphoblastic leukemia has improved because of intensive chemotherapy and supportive care. The frequency of adverse events has also increased, but the data related to acute central nervous system complications during acute lymphoblastic leukemia treatment are sparse. The purpose of this study is to evaluate these complications and to determine their long term outcome. We retrospectively analyzed the hospital reports of 323 children with de novo acute lymphoblastic leukemia from a 13-year period for acute neurological complications. The central nervous system complications of leukemic involvement, peripheral neuropathy, and post-treatment late-onset encephalopathy, and neurocognitive defects were excluded. Twenty-three of 323 children (7.1%) suffered from central nervous system complications during acute lymphoblastic leukemia treatment. The majority of these complications (n = 13/23; 56.5%) developed during the induction period. The complications included posterior reversible encephalopathy (n = 6), fungal abscess (n = 5), cerebrovascular lesions (n = 5), syndrome of inappropriate secretion of antidiuretic hormone (n = 4), and methotrexate encephalopathy (n = 3). Three of these 23 children (13%) died of central nervous system complications, one from an intracranial fungal abscess and the others from intracranial thrombosis. Seven of the survivors (n = 7/20; 35%) became epileptic and three of them had also developed mental and motor retardation. Acute central neurological complications are varied and require an urgent approach for proper diagnosis and treatment. Collaboration among the hematologist, radiologist, neurologist, microbiologist, and neurosurgeon is essential to prevent fatal outcome and serious morbidity. Copyright © 2015 Elsevier Inc.

Full Text Available We previously reported that radon inhalation activates antioxidative functions in the liver and inhibits carbon tetrachloride-induced hepatopathy in mice. In addition, it has been reported that reactive oxygen species contribute to alcohol-induced hepatopathy. In this study, we examined the inhibitory effects of radon inhalation on acute alcohol-induced hepatopathy in mice. C57BL/6J mice were subjected to intraperitoneal injection of 50% alcohol (5 g/kg bodyweight after inhaling approximately 4000 Bq/m3 radon for 24 h. Alcohol administration significantly increased the activities of glutamic oxaloacetic transaminase (GOT, glutamic pyruvic transaminase (GPT in serum, and the levels of triglyceride and lipid peroxide in the liver, suggesting acute alcohol-induced hepatopathy. Radon inhalation activated antioxidative functions in the liver. Furthermore, pretreatment with radon inhibited the depression of hepatic functions and antioxidative functions. These findings suggested that radon inhalation activated antioxidative functions in the liver and inhibited acute alcohol-induced hepatopathy in mice.

HLA-B27 is a transplantation antigen found in a high proportion of patients with ankylosing spondylitis. Recently, an association has been shown to exist between HLA-B27 and acute uveitis, even in the absence of ankylosing spondylitis. We have examined the HLA antigen profile of 45 patients with acute nongranulomatous anterior uveitis and have confirmed this relation. In addition, using 90mtechnetium stannous pyrophosphate we have been able to demonstrate abnormal bone scan in 19 of 30 patients studied. Such abnormalities are limited to the sacroiliac joints but are otherwise the same as those seen in overt ankylosing spondylitis. Seven of the 19 patients did not have HLA-B27. These factors suggest that acute anterior uveitis may often represent a manifestation of a spondylitic diathesis even in the complete absence of any suggestive symptomatic or radiologic change and, in some cases, even though the antigenic marker HLA-B27 may be absent.

Despite the frequent involvement of the spinal cord by multiple sclerosis, reports concerning neuroradiological findings regarding these lesions have been limited; most of them have demonstrated a normal or small spinal cord. Two cases of acute paraparesis showed evidence of spinal-cord swelling on myelography and CT myelography, initially suggesting the diagnosis of an intramedullary tumor. Spinal-cord swelling was demonstrated more clearly on CT myelography than on conventional myelography. The diagnosis of multiple sclerosis was made with the aid of the CSF findings, the clinical course, and the contracting-cord sign. The ''contracting-cord sign'' means the diminution of the spinal-cord diameter in the chronic stage. Since acute multiple sclerosis may produce spinal-cord swelling simulating a tumor, careful investigations are necessary to avoid unwarranted surgical interventions. (author)

Chromosome abnormalities in the acute phase of CML

Energy Technology Data Exchange (ETDEWEB)

Rowley, J D

1978-01-01

Additional chromosome changes are superimposed on the Ph/sup 1/ positive cell line in approximately 80% of patients in the acute phase of chronic myelogenous leukemia (CML). These changes may precede the onset of blast crisis by several months. They are nonrandom and frequently involve an extra No. 8, an isochromosome for the long arm of No. 17, an extra No. 19, and a second Ph/sup 1/ chromosome. Since such changes may occur in combination, modal numbers frequently range between 47 and 57 chromosomes. Although present evidence suggests that abnormal clones originate, or at least proliferate, in the spleen, similar changes have been observed in patients who underwent splenectomy during the chronic phase of their disease. The question of particular clinical-chromosomal correlations has been discussed in only one study. It appeared that patients whose karyotype did not change might have a longer median survival than those whose karyotype showed additional abnormalities. Tests for levels of terminal deoxynucleotidyl transferase (TDT) and response to anti-acute lymphoblastic leukemia (ALL) serum suggest that some, but not all patients react as do patients with ALL. Those who are similar to ALL have high levels of TDT and are anti-ALL serum-positive; the others have low levels of TDT and are anti-ALL serum-negative. In the future, correlations of these more sophisticated tests with the blast morphology, clinical course, and karyotype pattern should provide significant new insights into the acute phase of CML.

Air pollution and climate change have become key environmental and public health problems around the world, which poses serious threat to human health. How to assess and mitigate the health risks and increase the adaptation of the public have become an urgent topic of research in this area. The six papers in this issue will provide important and rich information on design, analysis method, indicator selection and setting about acute health risk assessment and adaptation study of air pollution and climate change in China, reflecting the advanced conceptions of multi-center and area-specific study and multi-pollutant causing acute effect study. However, the number and type of the cities included in these studies were still limited. In future, researchers should further expand detailed multi-center and multi-area study coverage, conduct area specific predicting and early warning study and strengthen adaptation study.

1986-01-01

Abnormal gastric wall configurations in 27 cases of cause-unknown acute gastritis were studied roentgenographically with reference to their causative origins. Studies were made on roentgenograms (abnormal gastric wall configurations), endoscopic findings and extension of lesions of the subjected cases. Gastric contour showed 'staying', 'thumbprinting', 'undulate configuration' and 'squarish undulation', while 'chimney-like' finding suggestive of poor gastric wall stretch was observed in the whole antral region as well. The widened angulus ventriculi and expanded pyloric ring (insufficient constriction) were also seen. In some cases the lesion extended over to the duodenum and, as in the cases of acute gastritis, duodenal wall 'staying', 'thumbprinting' and varied duodenal wall undulation were seen in addition to edema and morphological changes of the Kerkring's folds. The lesions in the studied patients mostly extended from an epicenter of the antrum upward to the gastric corpus and downward near to Vater's papilla in the descending part of the duodenum. The affected regions were clearly distinguishable. It has been known that above-described roentgenographical findings in our studied patients were similar in part to those known in experimental studies carried out on animals with ischemic digestive tract. This strongly suggests that some of our patients had developed the disease due to ischemic causes. There were some discrepancies between roentgenographical (abnormal gastric wall configuration) and endoscopic findings in some studied patients. It has been our belief that abnormal gastric wall configuration reflects lesions in the inner part of the wall and, accordingly, roentgenographical examinations, as well as endoscopy, should be performed for the purpose of making correct diagnosis. It is also to be emphasized that angiography should be carried out on patients with relapsing acute gastritis without any specific cause. (author)

Dietary supplementation of arginine has been used by numerous world-class athletes and professional bodybuilders over the past 30 years. L-Arginine indeed enhances muscular power and general performance via maintaining ATP level. However, L-arginine is also known to induce acute pancreatitis in murine models. We report the case of young man presenting with upper abdominal pain and increased serum lipase levels. Contrast-enhanced computed tomography confirms a mild acute pancreatitis. Common etiologies have been ruled out and toxicological anamnestic screening reveals the intake of protein powder. This is, to the best of our knowledge, the second case in human of arginine-induced acute pancreatitis. This case report suggests that every patient presenting with acute pancreatitis without obvious etiology should be evaluated for the intake of toxics other than alcohol, including L-arginine.

Kounis syndrome is an acute coronary syndrome in the context of a hypersensitivity reaction. The main pathophysiological mechanism appears to be coronary vasospasm. We report the case of a patient with a history of allergy to quinolones, who was given ciprofloxacin before an elective surgical procedure and during drug administration developed symptoms and electrocardiographic changes suggestive of ST-segment elevation acute coronary syndrome. The drug was suspended and coronary angiography excluded epicardial coronary disease. Two hours after withdrawal of the drug the symptoms and ST elevation had resolved completely.

Objective: To explore the relation between p53 genetic polymorphisms and radiotherapy-induced acute injury of mucosa of oral cavity mucosa. Methods: The total of 56 patients with NPC treated by radiotherapy alone or with chemoradiotherapy synchronically were genotyped for the p53 codon 72 pro-Arg SNP using PCR-RFLP assays, and were ranked according to the acute injury of oral cavity mucosa. Results: There was no difference in acute injury of oral cavity mucosa between the p53 Pro allele carriers and the other carriers (P>0.05); the high single dose (P<0.01) and concomitant chemoradiotherapy (P<0.05) resulted in increase in acute injury of oral cavity mucosa. Conclusion: Those results suggest that p53 SNP may not associate with radiotherapeutic acute injury of oral cavity mucosa. (authors)

Previously symptomatic and permanently asymptomatic carriers of a gene mutation for acute intermittent porphyria as well as matched controls were screened with regard to a series of variables of possible relevance to the development of porphyric symptoms. The basis for the study was a concept of acute porphyria as a condition of a permanent system overload of oxidative stress, with long term effects on hepatic and renal tissue, and with instances of periodic overload of free radicals giving rise to acute neurologic involvement. Leukocyte concentrations of manganese, calcium, iron and zinc, as well as erythrocyte calcium differed between the groups, acute intermittent porphyria gene carriers, irrespective of previous porphyric illness, showing significantly higher levels than the controls. Manganese was found to be the most discriminative component of all the 78 variables investigated, accounting for about 98 per cent of the variance between the groups. An increment, by a factor of four, in cellular manganese is suggestive of an increase, in acute intermittent porphyria, of a manganese associated enzyme, e.g. glutamine synthetase, pyruvate carboxylase or mitochondrial superoxide dismutase. The best fit into the model considered is provided by a theory focused on superoxide dismutase, induced in response to superoxide anion radical produced from aminolaevulinic acid. In porphyria gene carriers seemingly resistant to porphyric manifestations, an increase in potentially prooxidant cellular iron is matched by a proportional increment in manganese, i.e. presumably by a corresponding mitochondrial superoxide dismutase induction. This mechanism is not operative in porphyric individuals prone to development of neuropsychiatric symptoms. In acute intermittent porphyria with a history of porphyric illness there is a positive correlation between erythrocyte manganese and serum folate and a negative correlation between leukocyte ferrochelatase activity and serum cobalamin

Acute care in Tanzania: Epidemiology of acute care in a small community medical centre

Directory of Open Access Journals (Sweden)

Rachel M. Little

2013-12-01

Discussion: Respiratory infections, malaria, and skin or soft tissue infections are leading reasons for seeking medical care at a small community medical centre in Arusha, Tanzania, highlighting the burden of infectious diseases in this type of facility. Males may be more likely to present with trauma, burns, and laceration injuries than females. Many patients required one or no procedures to determine their diagnosis, most treatments administered were inexpensive, and most patients were discharged home, suggesting that providing acute care in this setting could be accomplished with limited resources.

Perioperative aspirin and clonidine and risk of acute kidney injury

DEFF Research Database (Denmark)

Garg, Amit X; Kurz, Andrea; Sessler, Daniel I

2014-01-01

IMPORTANCE: Acute kidney injury, a common complication of surgery, is associated with poor outcomes and high health care costs. Some studies suggest aspirin or clonidine administered during the perioperative period reduces the risk of acute kidney injury; however, these effects are uncertain...... and each intervention has the potential for harm. OBJECTIVE: To determine whether aspirin compared with placebo, and clonidine compared with placebo, alters the risk of perioperative acute kidney injury. DESIGN, SETTING, AND PARTICIPANTS: A 2 × 2 factorial randomized, blinded, clinical trial of 6905...... patients undergoing noncardiac surgery from 88 centers in 22 countries with consecutive patients enrolled between January 2011 and December 2013. INTERVENTIONS: Patients were assigned to take aspirin (200 mg) or placebo 2 to 4 hours before surgery and then aspirin (100 mg) or placebo daily up to 30 days...

IAP/APA evidence-based guidelines for the management of acute pancreatitis.

Science.gov (United States)

2013-01-01

There have been substantial improvements in the management of acute pancreatitis since the publication of the International Association of Pancreatology (IAP) treatment guidelines in 2002. A collaboration of the IAP and the American Pancreatic Association (APA) was undertaken to revise these guidelines using an evidence-based approach. Twelve multidisciplinary review groups performed systematic literature reviews to answer 38 predefined clinical questions. Recommendations were graded using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) system. The review groups presented their recommendations during the 2012 joint IAP/APA meeting. At this one-day, interactive conference, relevant remarks were voiced and overall agreement on each recommendation was quantified using plenary voting. The 38 recommendations covered 12 topics related to the clinical management of acute pancreatitis: A) diagnosis of acute pancreatitis and etiology, B) prognostication/predicting severity, C) imaging, D) fluid therapy, E) intensive care management, F) preventing infectious complications, G) nutritional support, H) biliary tract management, I) indications for intervention in necrotizing pancreatitis, J) timing of intervention in necrotizing pancreatitis, K) intervention strategies in necrotizing pancreatitis, and L) timing of cholecystectomy. Using the GRADE system, 21 of the 38 (55%) recommendations, were rated as 'strong' and plenary voting revealed 'strong agreement' for 34 (89%) recommendations. The 2012 IAP/APA guidelines provide recommendations concerning key aspects of medical and surgical management of acute pancreatitis based on the currently available evidence. These recommendations should serve as a reference standard for current management and guide future clinical research on acute pancreatitis. Copyright © 2013 IAP and EPC. Published by Elsevier B.V.

Full Text Available Objectives: Because most research on long-term acute care hospitals has focused on Medicare, the objective of this research is to describe the Georgia Medicaid population who received care at a long-term acute care hospital, the type and volume of services provided by these long-term acute care hospitals, and the costs and outcomes of these services. For those with select respiratory conditions, we descriptively compare costs and outcomes to those of patients who received care for the same services in acute care hospitals. Methods: We describe Georgia Medicaid recipients admitted to a long-term acute care hospital between 2011 and 2012. We compare them to a population of Georgia Medicaid recipients admitted to an acute care hospital for one of five respiratory diagnosis-related groups. Measurements used include patient descriptive information, admissions, diagnosis-related groups, length of stay, place of discharge, 90-day episode costs, readmissions, and patient risk scores. Results: We found that long-term acute care hospital admissions for Medicaid patients were fairly low (470 90-day episodes and restricted to complex cases. We also found that the majority of long-term acute care hospital patients were blind or disabled (71.2%. Compared to patients who stayed at an acute care hospital, long-term acute care hospital patients had higher average risk scores (13.1 versus 9.0, lengths of stay (61 versus 38 days, costs (US$143,898 versus US$115,056, but fewer discharges to the community (28.4% versus 51.8%. Conclusion: We found that the Medicaid population seeking care at long-term acute care hospitals is markedly different than the Medicare populations described in other long-term acute care hospital studies. In addition, our study revealed that Medicaid patients receiving select respiratory care at a long-term acute care hospital were distinct from Medicaid patients receiving similar care at an acute care hospital. Our findings suggest that

The purpose of this study was to assess the usefulness of helical CT in depicting the location of acute lower gastrointestinal bleeding. A three-phase helical CT of the abdomen was performed in 24 patients referred for acute lower gastrointestinal bleeding. The diagnosis of the bleeding site was established by CT when there was at least one of the following criteria: spontaneous hyperdensity of the peribowel fat; contrast enhancement of the bowel wall; vascular extravasation of the contrast medium; thickening of the bowel wall; polyp or tumor; or vascular dilation. Diverticula alone were not enough to locate the bleeding site. The results of CT were compared with the diagnosis obtained by colonoscopy, enteroscopy, or surgery. A definite diagnosis was made in 19 patients. The bleeding site was located in the small bowel in 5 patients and the colon in 14 patients. The CT correctly located 4 small bowel hemorrhages and 11 colonic hemorrhages. Diagnosis of the primary lesion responsible for the bleeding was made in 10 patients. Our results suggest that helical CT could be a good diagnostic tool in acute lower gastrointestinal bleeding to help the physician to diagnose the bleeding site. (orig.)

The role of schools of public health in capacity building.

Tulchinsky, Theodore H; Goodman, Julien

2012-08-01

Public health has been an enormously effective instrument for improving life expectancy and quality of life. Historically a sphere of governmental activity led by physicians and staffed by sanitarians and nurses, public health has evolved to become a multi-facetted field of societal activity. It engages many agencies and community action in reducing infectious and non-communicable diseases as well as many aspects of lifestyle and health equity. Education for an adequate professional workforce is one of its key functions. Schools of public health have fulfilled this role only partly even in developed countries, but in countries in transition and in low-income countries the problem is much more acute. We discuss the role of mentoring of new schools calling for strong public and private donor support for this as a key issue in global health.

Types of suggestibility: Relationships among compliance, indirect, and direct suggestibility.

Polczyk, Romuald; Pasek, Tomasz

2006-10-01

It is commonly believed that direct suggestibility, referring to overt influence, and indirect suggestibility, in which the intention to influence is hidden, correlate poorly. This study demonstrates that they are substantially related, provided that they tap similar areas of influence. Test results from 103 students, 55 women and 48 men, were entered into regression analyses. Indirect suggestibility, as measured by the Sensory Suggestibility Scale for Groups, and compliance, measured by the Gudjonsson Compliance Scale, were predictors of direct suggestibility, assessed with the Barber Suggestibility Scale. Spectral analyses showed that indirect suggestibility is more related to difficult tasks on the BSS, but compliance is more related to easy tasks on this scale.

Full Text Available Abstract Background Chlamydophila pneumoniae and Mycoplasma pneumoniae are associated with acute exacerbation of bronchial asthma (AEBA. The aim of this study was to evaluate the correlation between these acute bacterial infections and the severity of AEBA. Methods We prospectively analysed consecutive patients admitted to the Emergency Department with acute asthma exacerbation. In every patient peak expiratory flow (PEF measurement was performed on admission, and spirometry during follow-up. Serology for Chlamydophila and Mycoplasma pneumoniae was performed on admission and after 4–8 weeks. Results Fifty-eight patients completed the study. Acute atypical infections (AAI was observed in 22/58 cases; we found single acute C. pneumoniae in 19 cases, single acute M. pneumoniae in 2 cases, and double acute infection in one case. Functional impairment on admission was greater in patients with AAI than in patients without AAI (PEF 205 ± 104 L/min vs 276 ± 117 p = 0.02 and persisted until visit 2 (FEV1% 76.30 ± 24.54 vs FEV1% 92.91 ± 13.89, p = 0.002. Moreover, the proportion of patients who presented with severe AEBA was significantly greater in the group with AAI than in the group without AAI (15/22 vs 12/36, p = 0.01; OR 4.29, 95% CI 1.38–13.32. Conclusion Our data suggest an association between acute atypical infection and a more severe AEBA.

MacLachlan, Malcolm; Kavanagh, Bill; Kay, Alison

2012-01-01

International maritime health has largely developed within the sphere of occupational health services and international health problems. We reviewed publications in the journal International Maritime Health from 2000 to 2010 to establish the coverage of the journal and the scope of research in maritime health. We identified six thematic categories: healthcare access, delivery and integration; telehealth; non-communicable diseases and physical health problems; communicable diseases; psychological functioning and health; and safety-related issues. We describe the research within these themes and report on their publication prominence. We also analyse the research in terms of its geographical focus, the population groups addressed and the research methodologies used. We suggest a broadening of maritime research to include randomised controlled trials, longitudinal studies and more qualitative research; more research addressing the context for non-European seafarers; and research on seafarers spouses and family supports and obligations. We also recommend more research on psychosocial and cultural issues and on telehealth, as well as the development of a stronger systems perspective for promoting maritime health.

Experimental Investigation of the Time Course Effects of Acute Exercise on False Episodic Memory

Ali Siddiqui

2018-06-01

Full Text Available Previous experimental work suggests that acute exercise may positively influence the accurate recall of past episodic events. However, few studies have examined whether acute exercise also reduces the number of false episodic memories. We evaluated this paradigm in conjunction with an examination of the temporal effects of acute exercise, which have previously been shown to play an important role in subserving episodic memory function. Twenty young adults participated in three experimental visits, including a non-exercise control visit, a visit involving an acute bout (20 min of moderate-intensity exercise occurring prior to the memory task, and a visit involving an acute bout of exercise occurring during the encoding of the memory task. All visits were counterbalanced and occurred at least 24 h apart. The Deese–Roediger–McDermott (DRM Paradigm, involving a separate word list trial for each visit, was employed to assess accurate and false episodic memory recall. For each visit, a short-term (immediate recall and a long-term (25-min delay memory recall was assessed. For both time points, the visit that involved exercise prior to encoding resulted in better short-term and long-term memory function (F(2 = 11.56, p < 0.001, η2p = 0.38. For both time points, the control visit resulted in a greater number of false memories. These findings suggest that acute moderate-intensity exercise may help to increase the accurate recall of past episodic memories and may help to reduce the rate of false memories.

Integration of childhood TB into guidelines for the management of acute malnutrition in high burden countries.

Patel, L N; Detjen, A K

2017-06-21

Introduction: Childhood tuberculosis (TB) and undernutrition are major global public health challenges. In 2015, although an estimated 1 million children aged malnutrition from 17 high TB burden countries were reviewed to gather information on TB symptom screening, exposure history, and treatment. Results: Seven (41%) countries recommend routine TB screening among children with acute malnutrition, and six (35%) recommend obtaining a TB exposure history. Conclusion: TB screening is not consistently included in guidelines for acute malnutrition in high TB burden countries. Routine TB risk assessment, especially history of TB exposure, among acutely malnourished children, combined with improved linkages with TB services, would help increase TB case finding and could impact outcomes. Operational research on how best to integrate services at different levels of the health care system is needed.

Acute megakaryoblastic leukaemia (AMKL), a relatively rare type of acute myeloid leukaemia, is characterized by frequent involvement of the liver, spleen and lymph nodes in addition to myelofibrosis in children. Diagnosis is difficult both clinically and pathologically, and the hepatic or lymph node involvement is not uncommonly misinterpreted as solid tumour. We report the imaging findings of upper abdominal involvement by AMKL in an infant. The hepatic lesion, initially suspected to be hepatoblastoma, showed a distinctive appearance on MRI suggesting its infiltrative nature. With the association of splenic lesion and lymphadenopathy, the imaging findings were considered indicative of a haematological disorder. (orig.)

Systematic literature review for primary data using predefined inclusion, exclusion and validity criteria. Primary outcome measure was standardised neurological examination or neurological function. Secondary outcomes; acute mortality, early morbidity. To access the literature available to clinicians systematically and evaluate the evidence for an effect of high dose methylprednisolone (MPSS) on neurological improvement following acute spinal cord injury (ACSI). Information retrieval was based on Medline search (1966 through December 1999) using the strategy 'spinal cord injury' and 'methylprednisolone' (or 'dexamethasone') with no other restrictions. Primary data publications using high dose steroids given within 12 h following spinal cord injury and reporting outcome measures separately for steroid and non-steroid treated groups were selected. Evaluation followed the guides of Guyatt et al7 (for the Evidence Based Working Group in Canada). Studies with questionable validity were excluded. Level of evidence and treatment recommendation utilised the Canadian Task Force on the Periodic Health Examination criteria.6 Experimental spinal cord injury studies on larger animals were included; small mammal experiments were considered beyond evaluation. Three clinical trials and six cohort study publications were found to satisfy the review criteria. The evidence they provide supports 'the recommendation that the manoeuvre (high dose methylpredisolone) be excluded from consideration as an intervention for the condition'10 (acute spinal cord injury). Twelve larger animal publications were detailed. Validity and the functional significance of results was of concern in many. The weight of evidence lay with those studies demonstrating no definite effect of MPSS on functional outcome. In cat experiments with higher level cord damage, deaths in the MPSS treated groups were notable. The evidence produced by this systematic review does not support the use of high dose

Pancreatic ductal calculi are most often associated with chronic pancreatitis. Radiological features of chronic pancreatitis are readily evident in the presence of these calculi. However, acute pancreatitis due to a solitary main pancreatic ductal calculus of biliary origin is rare. A 59-year-old man presented with a first episode of acute pancreatitis. Contrast enhanced computerized tomography (CT) scan and endoscopic retrograde cholangiopancreatography (ERCP) revealed a calculus in the main pancreatic duct in the head of the pancreas causing acute pancreatitis. There were no features suggestive of chronic pancreatitis on CT scanning. The episode acute pancreatitis was managed conservatively. ERCP extraction of the calculus failed as the stone was impacted in the main pancreatic duct resulting in severe acute pancreatitis. Once this resolved, a transduodenal exploration and extraction of the pancreatic ductal calculus was performed successfully. Crystallographic analysis revealed the composition of the calculus was different to that seen in chronic pancreatitis, but more in keeping with a calculus of biliary origin. This could be explained by migration of the biliary calculus via the common channel into the main pancreatic duct. Following the operation the patient made an uneventful recovery and was well at two-year follow up. Acute pancreatitis due to a solitary main pancreatic ductal calculus of biliary origin is rare. Failing endoscopic extraction, transduodenal exploration and extraction is a safe option after resolution of acute pancreatitis.

A simplified study of public perception in the nuclear field: suggestions for educational campaign for different segments of society

Almeida, Renata Araujo de

2011-01-01

During the last years the need for the increase in the electricity energy production as much as in Brazil as in the rest of the world, has raised the tone o the debate about the environmental impacts as a result of these debates, the government and the Non-Governmental Organizations (NGO's) have requested several opinion researches aiming at measuring and evaluating the knowledge and perception of the public in relation to the best non-polluting energy sources. Prior to 2001 these researches would not make any sense in Brazil as the majority of its power grid is made of hydroelectric plants, a renewable energy source. However, when in that year it occurred a drought, the competent authorities have faced the necessity of developing a plan, the National Energy Plan (PNE2030) which recommends, among other objectives, finalizing the construction of the Angra 3 plant and the implementation Df new nuclear plants in places still to be determined. Even considering the complexity of the subject, this paper presents a field research realized from September 28th, 2010 to October 28th, 2010 of the current level of perception of the Brazilian population, specifically the residents of three cities of Rio de Janeiro, about the nuclear area. As a result of this work, it is suggested how the competent authorities should proceed to reach in an efficient manner, by means of communication campaigns both informative and educational, a greater understanding of the population about the proposed subject.

2018-04-01

In the past decade, arboviruses-arthropod-borne viruses-have been the focus of public health institutions worldwide following a spate of devastating outbreaks. Chikungunya virus, an arbovirus that belongs to the alphavirus genus, is a reemerging arthritogenic virus that has caused explosive outbreaks since 2006, notably on Réunion Island, and more recently in the Caribbean, South America, India, and Southeast Asia. The severity of arthritic disease caused by chikungunya virus has prompted public health authorities in affected countries to develop specific guidelines to tackle this pathogen. Chikungunya virus disease manifests first as an acute stage of severe joint inflammation and febrile illness, which later progresses to a chronic stage, during which patients may experience debilitating and persisting articular pain for extended periods. This review aims to provide a broad perspective on current knowledge of chikungunya virus pathogenesis by identifying key clinical and experimental studies that have contributed to our understanding of chikungunya virus to date. In addition, the review explores the practical aspects of treatment and management of both acute and chronic chikungunya virus based on clinical experience during chikungunya virus outbreaks. Finally, recent findings on potential therapeutic solutions-from antiviral agents to immunomodulators-are reviewed to provide both viral immunologists and clinical rheumatologists with a balanced perspective on the nature of a reemerging arboviral disease of significant public health concern, and insight into future therapeutic approaches to better address the treatment and management of chikungunya virus. © 2017, American College of Rheumatology.

Current Canadian And American Experiences In The Treatment Of Acute Ischemic Stroke

2017-02-01

Full Text Available Stroke remains one of the main public health issues worldwide. It is the third leading cause of death in the United States, with more than 200,000 people dying from strokes each year. Approximately 80% of all acute ischemic strokes are due to intracranial artery occlusion, most commonly thromboembolic clot occlusion. Revascularization of occluded territories is the cornerstone of acute ischemic stroke and Thrombolysis for ischemic stroke has been systematically studied in large randomized trials only since the 1990s. To date, thrombolytic therapy for ischemic stroke has been investigated in 21 randomized controlled clinical trials enrolling more than 7,000 patients. The advent of modern imaging and endovascular tools and technology has revolutionized treatment of stroke. In this talk, I will review current clinical trials published in The NEJM (ESCAPE, MR Clean, EXTENDED IA, …. regarding superiority of the endovascular treatments, especially, the stent retrievers, over Iv tPA. I will also go over all endovascular techniques used in the endovascular treatment of acute stroke using my Canadian and American experiences.

2006-11-01

Full Text Available Abstract Background Hornet stings are generally associated with local and occasionally anaphylactic reactions. Rarely systemic complications like acute renal failure can occur following multiple stings. Renal failure is usually due to development of acute tubular necrosis as a result of intravascular haemolysis, rhabdomyolysis or shock. Rarely it can be following development of acute tubulo-interstitial nephritis. Case presentation We describe a young male, who was stung on face, head, shoulders and upper limbs by multiple hornets (Vespa orientalis. He developed acute renal failure as a result of acute tubulo-interstitial nephritis and responded to steroids. Conclusion Rare causes of acute renal failure like tubulo-interstitial nephritis should be considered in a patient with persistent oliguria and azotemia following multiple hornet stings. Renal biopsy should be undertaken early, as institution of steroid therapy may help in recovery of renal function

Full Text Available Hymenoptera is a class of insects that sting in order to subdue their prey. Humans coming into accidental contact with these insects results in stings that may cause from mild local reaction like weal formation around the sting site to severe systemic reactions such as intravascular hemolysis, acute renal failure, pulmonary edema, cerebral edema, and rarely pancreatitis. We report here the clinical course of a patient who developed concurrent acute pancreatitis and pigment-induced acute renal failure after multiple hornet stings.

Aloe vera for treating acute and chronic wounds.

2012-02-15

Aloe vera is a cactus-like perennial succulent belonging to the Liliaceae Family that is commonly grown in tropical climates. Animal studies have suggested that Aloe vera may help accelerate the wound healing process. To determine the effects of Aloe vera-derived products (for example dressings and topical gels) on the healing of acute wounds (for example lacerations, surgical incisions and burns) and chronic wounds (for example infected wounds, arterial and venous ulcers). We searched the Cochrane Wounds Group Specialised Register (9 September 2011), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2011, Issue 3), Ovid MEDLINE (2005 to August Week 5 2011), Ovid MEDLINE (In-Process & Other Non-Indexed Citations 8 September 2011), Ovid EMBASE (2007 to 2010 Week 35), Ovid AMED (1985 to September 2011) and EBSCO CINAHL (1982 to 9 September 2011). We did not apply date or language restrictions. We included all randomised controlled trials that evaluated the effectiveness of Aloe vera, aloe-derived products and a combination of Aloe vera and other dressings as a treatment for acute or chronic wounds. There was no restriction in terms of source, date of publication or language. An objective measure of wound healing (either proportion of completely healed wounds or time to complete healing) was the primary endpoint. Two review authors independently carried out trial selection, data extraction and risk of bias assessment, checked by a third review author. Seven trials were eligible for inclusion, comprising a total of 347 participants. Five trials in people with acute wounds evaluated the effects of Aloe vera on burns, haemorrhoidectomy patients and skin biopsies. Aloe vera mucilage did not increase burn healing compared with silver sulfadiazine (risk ratio (RR) 1.41, 95% confidence interval (CI) 0.70 to 2.85). A reduction in healing time with Aloe vera was noted after haemorrhoidectomy (RR 16.33 days, 95% CI 3.46 to 77.15) and there was

Epidemiology of acute lymphoblastic leukemia

Pendergrass, T.W.

1985-01-01

Although the etiology of acute leukemia is largely unknown, some facets of the puzzle are becoming clarified. Recognition of important patterns in age-specific mortality rates has suggested that events early in life, perhaps even prenatally, may have an influence on developing leukemia in childhood. The racial differences evident in mortality, incidence, and immunologic subtype of ALL suggest either differences in exposures to certain factors or differences in responses to those factors by white children. Hereditary factors appear to play a role. Familial and hereditary conditions exist that have high incidences of acute leukemia. Chromosomal anomalies are common in these conditions. Viral infections may play a role by contributing to alteration in genetic material through incorporation of the viral genome. How that virus is dealt with after primary infection seems important. The presence of immunodeficiency may allow wider dissemination or enhanced replication of such viruses, thereby increasing the likelihood of cellular transformation to an abnormal cell. Proliferation of that malignant cell to a clone may depend on other cofactors. Perhaps prolonged exposure to substances like benzene or alkylating agents may enhance these interactions between virus and genetic material. Does this change DNA repair mechanisms. Are viral infections handled differently. Is viral genomic information more easily integrated into host cells. Ionizing radiation has multiple effects. Alteration in genetic material occurs both at the molecular and chromosomal levels. DNA may be altered, lost, or added in the cell's attempt to recover from the injury

Experimental Effects of Acute Exercise on Prospective Memory and False Memory.

Research demonstrates that acute exercise can enhance retrospective episodic memory performance. However, limited research has examined the effects of acute exercise on prospective memory, and no studies have examined the effects of exercise on false memory performance. This study examined the potential effects of acute exercise on prospective memory and false memory performance. A between-group randomized controlled trial was employed, with participants (college students; M age  = 20 years) randomized into an exercise group (15-minute acute bout of treadmill walking; N = 25) or a control group (15 minutes of sitting; N = 26). Prospective memory was assessed from two laboratory and two naturalistic assessments outside the lab. False memory was assessed using a word-list trial. There were no statistically significant differences in prospective memory based on group allocation (F Group×Time  = 1.17; P = 0.32; η 2  = 0.06). However, the control group recalled more false words and had a higher rate of false memory recognition (F Group×Time  = 3.15; P = 0.01; η 2  = 0.26). These findings indicate that acute moderate-intensity aerobic exercise is not associated with prospective memory performance but provides some suggestive evidence that acute exercise may reduce the rate of false memories.

The role of microglia in stress responses has recently been highlighted, yet the underlying mechanisms of action remain unresolved. The present study examined disruption in working memory due to acute stress using the water-immersion resistant stress (WIRS) test in mice. Mice were subjected to acute WIRS, and biochemical, immunohistochemical, and behavioral assessments were conducted. Spontaneous alternations (working memory) significantly decreased after exposure to acute WIRS for 2h. We employed a 3D morphological analysis and site- and microglia-specific gene analysis techniques to detect microglial activity. Morphological changes in hippocampal microglia were not observed after acute stress, even when assessing ramification ratios and cell somata volumes. Interestingly, hippocampal tumor necrosis factor (TNF)-α levels were significantly elevated after acute stress, and acute stress-induced TNF-α was produced by hippocampal-ramified microglia. Conversely, plasma concentrations of TNF-α were not elevated after acute stress. Etanercept (TNF-α inhibitor) recovered working memory deficits in accordance with hippocampal TNF-α reductions. Overall, results suggest that TNF-α from hippocampal microglia is a key contributor to early-stage stress-to-mental responses. Copyright © 2015 Elsevier Inc. All rights reserved.

Acute Respiratory Distress Syndrome (ARDS) is due to many causes. The absence of a universal definition up until now has led to a series of practical problems for a definitive diagnosis. The incidences of ARDS and Acute Lung Injury (ALI) vary widely in the current literature. The American-European Consensus Conference definition has been applied since its publication in 1994 and has helped to improve knowledge about ARDS. However, 18 years later, in 2011, the European Intensive Medicine Society, requested a team of international experts to meet in Berlin to review the ARDS definition. The purpose of the Berlin definition is not to use it as a prognostic tool, but to improve coherence between research and clinical practice.

Full Text Available Publications of recent years do not reflect the regional dynamics of hospitalization of patients with acute surgical pathology of the abdominal cavity and anterior abdominal wall. Goal – to determine the volume of hospitalizations and treatment of patients with acute surgical pathology of the abdominal and anterior abdominal wall in the Kuzbass in the dynamics from 1993 to 2016. Materials and methods. A comparative analysis of the volume of treatment of patients with acute appendicitis, acute cholecystitis, acute pancreatitis, intestinal obstruction, perforated ulcer of the stomach and duodenum and strangulated hernia in surgical departments of Kuzbass from 1993 to 2016 to understand the changes occurring in abdominal surgery. Estimated in the comparative aspect for two decades (1993-2002 and 2007-2016 the average annual number of treated. The estimation of indicators in calculation on 100000 population is executed. The statistical processing was carried out using IBM SPSS Statistica computer version 24 and the nonparametric Mann-Whitney test. Result. Statistically significantly decreased the number of patients with acute appendicitis and perforated ulcers of the stomach and duodenum. The average annual hospitalization of patients with acute pancreatitis and strangulated abdominal hernias has significantly increased in the last decade. There are no significant differences in the increase in the total number of patients with acute cholecystitis and acute intestinal obstruction. Conclusions: 1. Over the past decade compared with 1993-2002, the incidence of acute appendicitis per 100000 thousand of the population decreased in the region by 39.9 %, the incidence of perforated gastric ulcer and duodenal ulcer by 30.2 %. 2. At this time, the number of people treated with 100000 people with acute pancreatitis increased by 94.7 %; with acute cholecystitis by 12.4 %; with an acute intestinal obstruction by 9.8 % and with a strangulated

2013-06-01

Acute appendicitis is a common medical condition, whose effective, timely diagnosis can be difficult. A missed diagnosis not only puts the patient in danger but also requires additional resources for corrective treatments. An acute appendicitis diagnosis constitutes a classification problem, for which a further fundamental challenge pertains to the skewed outcome class distribution of instances in the training sample. A preclustering-based ensemble learning (PEL) technique aims to address the associated imbalanced sample learning problems and thereby support the timely, accurate diagnosis of acute appendicitis. The proposed PEL technique employs undersampling to reduce the number of majority-class instances in a training sample, uses preclustering to group similar majority-class instances into multiple groups, and selects from each group representative instances to create more balanced samples. The PEL technique thereby reduces potential information loss from random undersampling. It also takes advantage of ensemble learning to improve performance. We empirically evaluate this proposed technique with 574 clinical cases obtained from a comprehensive tertiary hospital in southern Taiwan, using several prevalent techniques and a salient scoring system as benchmarks. The comparative results show that PEL is more effective and less biased than any benchmarks. The proposed PEL technique seems more sensitive to identifying positive acute appendicitis than the commonly used Alvarado scoring system and exhibits higher specificity in identifying negative acute appendicitis. In addition, the sensitivity and specificity values of PEL appear higher than those of the investigated benchmarks that follow the resampling approach. Our analysis suggests PEL benefits from the more representative majority-class instances in the training sample. According to our overall evaluation results, PEL records the best overall performance, and its area under the curve measure reaches 0.619. The

2013-01-01

Acute onset neuropsychiatric manifestations in hypopituitarism are uncommon. We report a case of a 60-year-old man who was a follow-up case of macroprolactinoma with hypopituitarism for the last 9 years. He was on medical treatment with cabergoline, thyroxine and depot testosterone. During the last 2 years he was non-adherent to medications especially cabergoline. He was hospitalised for 2 days through emergency services following acute onset psychosis. His pituitary hormone profile was suggestive of adrenal insufficiency, secondary hypothyroidism and hypogonadism. MRI of the hypothalamic pituitary region revealed a pituitary macroadenoma which was larger in size compared to the previous scan. Further, this lesion was compressing on the adjoining structures including optic chiasma. The patient was treated with intravenous fluids, hydrocortisone and thyroxine replacement therapy. With this treatment he completely recovered from psychosis within 48 h. PMID:23853186

Abbrederis, K; Schmalzl, F

1976-01-01

The usefulness for clinical purposes of the distinction of acute undifferentiated (AUL) and acute lymphocytic leukemia (ALL) is suggested by the following observations: 1. Maturation from AUL to ALL has not been observed. Transformation of ALL to AUL has been reported i.e. less of cytoplasmic polysaccharides; however this seems rather to be the effect of cytotoxic therapy and not a real change of the cytological type. 2. Significant differences among ALL and AUL can be noted as far as the therapeutic response is concerned: All of the 9 patients with ALL but only 2 out of 9 patients with AUL went into remission. The mean survival of the cases with ALL amounts to 34, that of AUL only to 4 months. Out of the patients with ALL 4 patients are still alive in persistant first remission after 77, 57, 36 and 28 months. 3. ALL occurs most frequently in young adults (mean age of 21 patients: 31.7 years): AUL is more frequent in elderly patients (Mean age of 18 patients: 57.6 years). 4. In our material ALL did never occur consequent to a typical preluekemic stage, which was followed either by myeloblastic, monocytic, erythroleukemic or undifferentiated leukemias.

The public health relevance of air pollution abatement.

Science.gov (United States)

Künzli, N

2002-07-01

Assuming a causal relationship between current levels of air pollution and morbidity/mortality, it is crucial to estimate the public health relevance of the problem. The derivation of air pollution attributable cases faces inherent uncertainties and requires influential assumptions. Based on the results of the trinational impact assessment study of Austria, France, and Switzerland, where prudent estimates of the air pollution attributable cases (mortality, chronic bronchitis incidence, hospital admissions, acute bronchitis among children, restricted activity days, asthma attacks) have been made, influential uncertainties are quantified in this review. The public health impact of smoking, environmental tobacco smoke, and air pollution on the prevalence of chronic cough/phlegm are outlined. Despite all methodological caveats, impact assessment studies clearly suggest that public health largely benefits from better air quality. The studies are selective underestimates as they are strongly driven by mortality, but do not include full quantification of the impact on morbidity and their consequences on quality of life among the diseased and the caregivers. Air pollution abatement strategies are usually political in nature, targeting at polities, regulation and technology in mobile or stationary sources rather than at individuals. It is of note that key clean air strategies converge into abatement of climate change. In general, energy consumption is very closely related to both air pollution and greenhouse gases. The dominant causes of both problems are the excessive and inefficient combustion of fossil fuel. Thus, for many policy options, the benefit of air pollution abatement will go far beyond what prudent health-impact assessments may derive. From a climate change and air pollution perspective, improved energy efficiency and a strong and decisive departure from the "fossil fuel" combustion society is a science-based must. Health professionals must raise their voices

Horrocks Julie

2007-07-01

Full Text Available Abstract Background Gastrointestinal illness is an important global public health issue, even in developed countries, where the morbidity and economic impact are significant. Our objective was to evaluate the demographic determinants of acute gastrointestinal illness in Canadians. Methods We used data from two population-based studies conducted in select communities between 2001 and 2003. Together, the studies comprised 8,108 randomly selected respondents; proxies were used for all respondents under 12 years and for respondents under 19 years at the discretion of the parent or guardian. Using univariate and multivariate logistic regression, we evaluated the following demographic determinants: age, gender, cultural group, and urban/rural status of the respondent, highest education level of the respondent or proxy, number of people in the household, and total annual household income. Two-way interaction terms were included in the multivariate analyses. The final multivariate model included income, age, gender, and the interaction between income and gender. Results After adjusting for income, gender, and their interaction, children under 10 years had the highest risk of acute gastrointestinal illness, followed by young adults aged 20 to 24 years. For males, the risk of acute gastrointestinal illness was similar across all income levels, but for females the risk was much higher in the lowest income category. Specifically, in those with total annual household incomes of less than $20,000, the odds of acute gastrointestinal illness were 2.46 times higher in females than in males. Conclusion Understanding the demographic determinants of acute gastrointestinal illness is essential in order to identify vulnerable groups to which intervention and prevention efforts can be targeted.

Acute dental infections managed in an outpatient parenteral antibiotic program setting: prospective analysis and public health implications.

The number of Acute Dental Infections (ADI) presenting for emergency department (ED) care are steadily increasing. Outpatient Parenteral Antibiotic Therapy (OPAT) programs are increasingly utilized as an alternative cost-effective approach to the management of serious infectious diseases but their role in the management of severe ADI is not established. This study aims to address this knowledge gap through evaluation of ADI referrals to a regional OPAT program in a large Canadian center. All adult ED and OPAT program ADI referrals from four acute care adult hospitals in Calgary, Alberta, were quantified using ICD diagnosis codes in a regional reporting system. Citywide OPAT program referrals were prospectively enrolled over a five-month period from February to June 2014. Participants completed a questionnaire and OPAT medical records were reviewed upon completion of care. Of 704 adults presenting to acute care facilities with dental infections during the study period 343 (49%) were referred to OPAT for ADI treatment and 110 were included in the study. Participant mean age was 44 years, 55% were women, and a majority of participants had dental insurance (65%), had seen a dentist in the past six months (65%) and reported prior dental infections (77%), 36% reporting the current ADI as a recurrence. Median length of parenteral antibiotic therapy was 3 days, average total course of antibiotics was 15-days, with a cumulative 1326 antibiotic days over the study period. There was no difference in total duration of antibiotics between broad and narrow spectrum regimes. Conservative cost estimate of OPAT care was $120,096, a cost savings of $597,434 (83%) compared with hospitalization. ADI represent a common preventable cause of recurrent morbidity. Although OPAT programs may offer short-term cost savings compared with hospitalization, risks associated with extended antibiotic exposures and delayed definitive dental management must also be gauged.

Acute Predictors of Social Integration Following Mild Stroke.

2018-04-01

Despite an acknowledged need to accurately predict stroke outcome, there is little empirical evidence regarding acute predictors of participation restriction post stroke. The current study examines prediction of social integration following mild stroke, using combinations of acute poststroke factors. In a prospective, longitudinal study, a cohort of 60 stroke survivors was followed up at 6 months post stroke. Hierarchical multiple regression analyses were employed to evaluate the value of acute poststroke variables in predicting social integration at 6 months post stroke. A combination of age, number of comorbidities, stroke severity, social support factors, and general self-efficacy in the acute poststroke period accounted for 42% of the variance in 6-month social integration. The largest amount of variance (20%) was explained by inclusion of social support factors, including number and types of support. Post hoc analysis was conducted to establish whether marital status was the mediating variable through which early poststroke social support factors exerted influence upon subsequent social integration. The new combination of acute variables accounted for 48% of the variance in 6-month social integration. Results suggested that subjects with partners perceived higher levels of functional social support and lower levels of participation restriction. Stroke survivors with partners may receive greater amounts of companionship and encouragement from their partners, which enhances self-esteem and confidence. Such individuals are possibly more able to participate in and maintain relationships, thus improving social integration. Social support factors, mediated via marital status, are the strongest predictors of subsequent social integration following mild stroke. Copyright © 2018 National Stroke Association.

Prognostic factors in neonatal acute renal failure

Chevalier, R.L.; Campbell, F.; Brenbridge, A.N.

1984-01-01

Sixteen infants, 2 to 35 days of age, had acute renal failure, a diagnosis based on serum creatinine concentrations greater than 1.5 mg/dL for at least 24 hours. Eight infants were oliguric (urine flow less than 1.0 mL/kg/h) whereas the remainder were nonoliguric. To determine clinical parameters useful in prognosis, urine flow rate, duration of anuria, peak serum creatinine, urea (BUN) concentration, and nuclide uptake by scintigraphy were correlated with recovery. Nine infants had acute renal failure secondary to perinatal asphyxia, three had acute renal failure as a result of congenital cardiovascular disease, and four had major renal anomalies. Four oliguric patients died: three of renal failure and one of heart failure. All nonoliguric infants survived with mean follow-up serum creatinine concentration of 0.8 +/- 0.5 (SD) mg/dL whereas that of oliguric survivors was 0.6 +/- 0.3 mg/dL. Peak serum creatinine concentration did not differ between those patients who were dying and those recovering. All infants who were dying remained anuric at least four days and revealed no renal uptake of nuclide. Eleven survivors were anuric three days or less, and renal perfusion was detectable by scintigraphy in each case. However, the remaining survivor (with bilateral renal vein thrombosis) recovered after 15 days of anuria despite nonvisualization of kidneys by scintigraphy. In neonates with ischemic acute renal failure, lack of oliguria and the presence of identifiable renal uptake of nuclide suggest a favorable prognosis

Acute erythremic myelosis (true erythroleukaemia): a variant of AML FAB-M6.

Science.gov (United States)

Hasserjian, R P; Howard, J; Wood, A; Henry, K; Bain, B

2001-03-01

Classic erythroleukaemia (acute myeloid leukaemia M6, or M6 AML) is defined as an excess of myeloblasts in an erythroid predominant background. Leukaemia variants in which the primitive blast cells are demonstrably erythroid are extremely rare and poorly characterised. Variably referred to as "true erythroleukaemia" or "acute erythremic myelosis", they are often included within the M6 AML category even though they do not meet strict criteria for this type of AML. Two cases of acute erythroid neoplasia are presented with clinical, morphological, immunophenotypic, and cytogenetic analysis. Both patients presented with profound anaemia, one in a setting of long standing myelodysplasia. Bone marrow examination revealed a predominant population of highly dysplastic erythroid cells in both cases. In one case, the liver was infiltrated by neoplastic erythroid cells. Both patients died within four months of diagnosis. This report illustrates that cases of acute leukaemia occur in which the dominant neoplastic cell is a primitive erythroid cell without an accompanying increase in myeloblasts. This does not preclude the neoplastic clone originating in a multipotent haemopoietic stem cell, as suggested by cases arising in patients with myelodysplasia. Acute erythremic myelosis should be recognised as a distinct variant of M6 AML.

Acute toxicity and associated mechanisms of four strobilurins in algae.

Strobilurins have been reported highly toxic to non-target aquatic organisms but few illustrated how they cause toxic effects on algae. This study investigated the acute toxicity of Kresoxim-methy (KRE), Pyraclostrobin (PYR), Trifloxystrobin (TRI) and Picoxystrobin (PIC) on two algae and their toxicity mechanisms. Four strobilurins showed lower toxic effects on Chlorella pyrenoidsa but higher on Chlorella vulgaris. bc1 complex activities in C. vulgaris were significantly inhibited by all strobilurins, suggesting bc 1 complex might be the target of strobilurin toxicity in algae. Moreover, SOD, CAT and POD activities were significantly up-regulated by all doses of KRE, PYR and PIC. In contrast, low concentrations of TRI stimulated SOD and POD activities but highest concentration significantly inhibited those activities. Comet assays showed damaged DNA in C. vulgaris by four strobulirins, suggesting their potential genotoxic threats to algae. The results illustrated acute toxicity by strobulirins on algae and their possible toxicity mechanisms. Copyright © 2018 Elsevier B.V. All rights reserved.

Acute anal pain is a common proctological problem. A detailed history together with the clinical examination are crucial for the diagnosis. An acute perianal vein thrombosis can be successfully excised within the first 72 hours. Acute anal fissures are best treated conservatively using stool regulation and topical medications reducing the sphincter spasm. A chronic anal fissure needs surgery. Perianal abscesses can very often be incised and drained in local anesthesia. Proctalgia fugax and the levator ani syndrome are exclusion diagnoses and are treated symptomatically.

Full Text Available With a view to standardizing the contents offered to future Accounting professionals, the Federal Accounting Council (CFC elaborated the National Proposal for Undergraduate Accountancy Program Contents. Thus, the curriculum that Higher Education Institutions (HEI adopt serves as an ally for students’ professional conquests. Stability and favorable job conditions attract many people to the dispute for a public function, with a growing Braz ilian public competitive examination market. According to the National Association for Protection and Support to Public Competitive Examinations (Anpac, between 2003 and 2009, the number of public servants in the executive power with a higher education degree in Brazil increased by 26%. The aim of this study was to confront the CFC’s suggested knowledge with the contents required during tests applied in public competitive examinations for Accountancy professionals. The intent is to identify what Public Accounting knowledge is demanded from candidates for the public career.

Posterior reversible encephalopathy syndrome (PRES) is known to be caused by a variety of clinical disorders. The authors encountered a case of PRES associated with acute pancreatitis and chronic alcoholism. A 49-year-old man presented with altered mental status. Magnetic resonance imaging (MRI) displayed vasogenic edema at the bilateral posterior temporal and parieto-occipital lobes and cerebellum. Laboratory tests and abdominal computed tomography (CT) revealed acute pancreatitis. The patient recovered completely, and follow-up brain MRI and abdominal CT exhibited resolution of the previous lesions. We suggest that acute pancreatitis might be an etiology of PRES.

Full Text Available AIM: A potential link between infectious agents and atherosclerosis has been suggested. Data obtained from several seroepidemiological studies have suggested that infection with Chlamydophila pneumoniae, Helicobacter pylori, and Cytomegalovirus can initiate or maintain the atherosclerotic process. Aim of this study is to evaluate the probable relationship between serum titers of some various infectious agents and the development of acute coronary syndrome and to investigate the relationship between these infectious agents and other risk factors of acute coronary syndrome (smoking, hypertension, dyslipidemia, diabetes, and family history of CVD. METHOD: This is a hospital based case- control study was conducted on two groups: patients group included 86 patients, cases were collected from patients admitted to Cardiac Care Unit (CCU of Cleopatra hospital, and Ain Shams University hospital with acute myocardial infarction between January 2010 and June 2010 and control group included 86 apparently healthy individuals. A questionnaire was designed to determine conventional coronary artery risk factors. The sero-prevalence of Chlamydia pneumoniae (C. pneumoniae, Cytomegalovirus and Helicobacter pylori (H. pylori IgG antibodies were evaluated using quantitative enzyme-linked immunosorbent assay (ELISA. RESULTS: The results showed that there was an increased level of serum IgG antibodies of C. pneumoniae, Cytomegalovirus and Helicobacter pylori among patients with acute coronary syndrome compared to control subjects CONCLUSION: C. pneumoniae, Cytomegalovirus and Helicobacter pylori were expected to be predictors for the development of coronary artery disease, as there was significant elevation of the serum level of IgG antibodies against them.

Patients who are diagnosed with acute lung injury/acute respiratory distress syndrome (ALI/ARDS) usually have ventilation-perfusion mismatch, severe decrease in lung capacity, and gas exchange abnormalities. Health care workers have implemented various strategies in an attempt to compensate for these pathological alterations. By rotating patients with ALI/ARDS between the supine and prone position, it is possible to achieve a significant improvement in PaO2/FiO2, decrease shunting and therefore improve oxygenation without use of expensive, invasive and experimental procedures. Prone positioning is a safe and effective way to improve ventilation when conventional strategies fail to initiate a patient response. Because a specific cure for ARDS is not available, the goal is to support the patients with therapies that cause the least amount of injury while the lungs have an opportunity to heal. Based on current data, a trial of prone positioning ventilation should be offered to the patients who have ALI/ARDS in the early course of the disease. Published studies exhibit substantial heterogeneity in clinical results, suggesting that an adequately sized study optimizing the duration of proning ventilation strategy is warranted to enable definitive conclusions to be drawn.

Previous laboratory studies have suggested that pyraclostrobin-containing fungicide formulations are toxic to amphibians at environmentally relevant concentrations. However, it is unknown if all pyraclostrobin formulations have similar toxicity and if toxicity occurs in different amphibian species. We investigated the acute toxicity of two formulations, Headline(®) fungicide and Headline AMP(®) fungicide, to Blanchard's cricket frogs (Acris blanchardi) based on a direct overspray scenario. In addition, we examined body residues of fungicide active ingredients in A. blanchardi following direct exposure to Headline AMP fungicide. Headline fungicide and Headline AMP fungicide had similar toxicity to A. blanchardi with calculated median lethal doses of 2.1 and 1.7 µg pyraclostrobin/cm(2), respectively, which are similar to the suggested maximum label rate in North American corn (2.2 and 1.52 µg pyraclostrobin/cm(2), respectively). Tissue concentrations of pyraclostrobin were lower than predicted based on full uptake of a direct dose, and did not drop during the first 24 h after exposure. Headline fungicides at corn application rates are acutely toxic to cricket frogs, but acute toxicity in the field will depend on worst-case exposure.

2017-10-01

Acute hypertensive response is elevation of systolic blood pressure (SBP) in the first 24 h after symptom onset which is highly prevalent in patients with intracerebral hemorrhage (ICH). Observational studies suggested association between acute hypertensive response and hematoma expansion, peri-hematoma edema and death and disability, and possible reduction in these adverse outcomes with treatment of acute hypertensive response. Recent clinical trials have focused on determining the clinical efficacy of early intensive SBP reduction in ICH patients. The Antihypertensive Treatment of Acute Cerebral Hemorrhage (ATACH-2) trial was the latest phase 3 randomized controlled multicenter clinical trial aimed to study the efficacy of early intensive reduction of SBP in ICH patients. In this review article, we summarize the results of recent clinical trials, treatment principles based on the latest guidelines, and the anticipated interpretation and incorporation of ATACH-2 trial results in clinical practice.

Acute toxicity in head and neck (H and N) cancer patients treated with definitive radiotherapy (RT) has a crucial role in compliance to treatments. The aim of this study was to correlate doses to swallowing-associated structures and acute dysphagia. We prospectively analyzed 42 H and N cancer patients treated with RT. Dysphagia (grade ≥ 3) and indication for percutaneous endoscopic gastrostomy (PEG) insertion were classified as acute toxicity. Ten swallowing-related structures were considered for the dosimetric analysis. The correlation between clinical information and the dose absorbed by the contoured structures was analyzed. Multivariate logistic regression method using resampling methods (bootstrapping) was applied to select model order and parameters for normal tissue complication probability (NTCP) modelling. A strong multiple correlation between dosimetric parameters was found. A two-variable model was suggested as the optimal order by bootstrap method. The optimal model (Rs = 0.452, p < 0.001) includes V 45 of the cervical esophagus (odds ratio [OR] = 1.016) and D mean of the cricopharyngeal muscle (OR = 1.057). The model area under the curve was 0.82 (95% confidence interval 0.69-0.95). Our results suggested that the absorbed dose to the cricopharyngeal muscle and cervical esophagus might play a relevant role in the development of acute RT-related dysphagia. (orig.) [de

As the opioid epidemic continues, understanding manifestations of abuse, including heroin-associated myelopathy remains essential. Here we describe a young man with a past medical history significant for polysubstance abuse who developed acute-onset, rapidly progressive myelopathy after resumption of intravenous heroin use. He had significant spinal cord involvement with findings suggestive of heroin-associated myelopathy. The salient features of this case include diffusion imaging of the spine and spinal angiography supporting a possible vasculopathy as the pathophysiologic mechanism underlying heroin-associated myelopathy. Additionally, CSF studies showed the transition from a neutrophilic pleocytosis to a lymphocytic pleocytosis suggesting an inflammatory component. Copyright © 2018 Elsevier Ltd. All rights reserved.

To determine the value of transvaginal sonography in evaluating women with acute pelvic inflammatory disease (PID). Transvaginal sonography was performed in 25 patients with clinically suggested PID during recent 36 months. The sonographic findings of fallopian tubes and ovaries were analyzed and correlated with pathological findings of 2 fallopian tubes and 19 ovaries in 16 patients who had operations. The correct diagnosis of acute PID was made in 20/25 (80%) by transvaginal sonography. the abnormal sonographic findings of the fallopian tube include tubal thickening or dilatation with internal echo. The sensitivity, specificity, and accuracy for tubal abnormality were 88%, 96%, and 86% , respectively. Ovarian changes were seen on TVS in 14/19 (73%), which include multiple follicular enlargement in 5, tubo-ovarian complex in 9 (tubo-ovarian adhesion in 3, tubo-ovarian abscess in 6). At surgery, the ovay was not involved in all three women who showed tubo-ovarian adhesion on TVS. Among 6 women who showed tubo-ovarian abscess on TVS, tubo-ovarian abscess was confirmed in 3 and the remaining 3 had ovarian cysts. Trandvaginal sonography, a facilitative and accurate modality, is highly sensitive in detecting the abnormality of the tube and useful in differentiating the tubo-ovarian complex in patients with acute PID.

Appendectomy has remained the gold standard treatment of acute appendicitis for more than 100years. Nonoperative management (NOM) has been shown to be a valid treatment alternative for acute uncomplicated appendicitis in adults. A systematic review of available evidence comparing operative management (OM) and NOM in children with acute uncomplicated appendicitis was performed. Systematic searches of MedLine, Embase, and a clinical trial register (https://clinicaltrials.gov/) were performed in March 2016. Only articles that studied NOM for uncomplicated appendicitis in children were included. Data generation was performed independently by two authors, and quality was assessed using the rating schema by the Oxford Centre for Evidence-Based Medicine. 15 articles were selected: four retrospective analyses, four prospective cohort studies, four prospective nonrandomized comparative trials and one randomized controlled trial (RCT). Initial success of the NOM groups (a cure within two weeks of intervention) ranged from 58 to 100%, with 0.1-31.8% recurrence at one year. Although present literature is scarce, publications support the feasibility of further studies investigating NOM of acute uncomplicated appendicitis in children. Higher quality prospective RCTs with larger sample sizes and robust randomization methods, studying the noninferiority of NOM with antibiotics compared with OM are required to establish its utility. This manuscript is a systematic review and thus assigned the lowest evidence used from the manuscripts analyzed which is a Level IV. Copyright © 2017. Published by Elsevier Inc.

Full Text Available Public management can and should be taught. Former Soviet Republics, including Georgia are facing this acute problem. Some attention is directed to management training, but public management stays in the background, although it is evident that major political and economic problems of Georgia and other countries of so-called “fledging democracies” arise due to the government theory neglect. The article considers development of administrative way of thinking starting from political doctrine to managerial approach, prospects for public management principles development, existing educational models. The epoch of classic universities is passing; with the help of textbooks students can only make courseworks. That’s why the use of innovative methods is necessary for students training.

2003-09-01

This prospective audit of incidence and outcome of the acute respiratory distress syndrome was conducted as part of the national audit of intensive care practice in Scotland. All patients with acute respiratory distress syndrome in 23 adult intensive care units were identified using the diagnostic criteria defined by the American-European Consensus Conference. Daily data collection was continued until death or intensive care unit discharge. Three hundred and sixty-nine patients were diagnosed with acute respiratory distress syndrome over the 8-month study period. The frequency of acute respiratory distress syndrome in the intensive care unit population was 8.1%; the incidence in the Scottish population was estimated at 16.0 cases.100,000(-1).year(-1). Intensive care unit mortality for acute respiratory distress syndrome was 53.1%, with a hospital mortality of 60.9%. In our national unselected population of critically ill patients, the overall outcome is comparable with published series (Acute Physiology and Chronic Health Evaluation II standardised mortality ratio = 0.99). However, mortality from acute respiratory distress syndrome in Scotland is substantially higher than in recent other series suggesting an improvement in outcome in this condition.

Viral-bacterial and bacterial synergism have been suggested to contribute to the pathogenesis of several human diseases. This study sought to investigate the possible associations between 9 candidate endodontic bacterial pathogens and 9 human viruses in samples from acute apical abscesses. DNA extracts from purulent exudate aspirates of 33 cases of acute apical abscess were surveyed for the presence of 9 selected bacterial species using a 16S ribosomal RNA gene-based nested polymerase chain reaction (PCR) approach. Single or nested PCR assays were used for detection of the human papillomavirus (HPV) and herpesviruses types 1 to 8. Two-thirds of the abscess samples were positive for at least one of the target viruses. Specifically, the most frequently detected viruses were HHV-8 (54.5%); HPV (9%); and varicella zoster virus (VZV), Epstein-Barr virus (EBV), and HHV-6 (6%). Bacterial DNA was present in all cases and the most prevalent bacterial species were Treponema denticola (70%), Tannerella forsythia (67%), Porphyromonas endodontalis (67%), Dialister invisus (61%), and Dialister pneumosintes (57.5%). HHV-8 was positively associated with 7 of the target bacterial species and HPV with 4, but all these associations were weak. Several bacterial pairs showed a moderate positive association. Viral coinfection was found in 6 abscess cases, but no significant viral association could be determined. Findings demonstrated that bacterial and viral DNA occurred concomitantly in two-thirds of the samples from endodontic abscesses. Although this may suggest a role for viruses in the etiology of apical abscesses, the possibility also exists that the presence of viruses in abscess samples is merely a consequence of the bacterially induced disease process. Further studies are necessary to clarify the role of these viral-bacterial interactions, if any, in the pathogenesis of acute apical abscesses. Copyright © 2011 Mosby, Inc. All rights reserved.

To evaluate he usefulness of the paramagnetic contrast agent Gadolinium-DTPA (diethylenetriaminepentaacetic acid) in Magnetic Resonance. Imaging of acute myocardial infarction, we studied a total of 45 patients with a first acute myocardial infarction by ECG-gated magnetic resonance imaging before and after intravenous administration of 0.1 mmol/kg Gadolinium-DTPA. All patients received thrombolytic treatment by intravenous streptokinase. The magnetic resonance imaging studies were preformed after a meam of 88 h (range 15-241) after the acute onset of acute myocardial infarction. Five patients without evidence of cardiac disease served as controls. Spin-echo measurements (TE 30 ms) were made using a Philips Gyroscan (0.5 Tesla) or a Teslacon II (0.6 Tesla). The 45 patients were divided into four groups of patients. In Group I( patients) Gadolinium-DTPA improved the detection of myocardial infarction by Gadolinium-DTPA. In Group II (20 patients) the magnetic resonance imaging procedure was repeated every 10 min for up to 40 min following administration of Gadolinium-DTPA. Optimal contrast enhancement was obtained 20-25 min after Gadolinium-DTPA. In Group III (27 patients) signal intensities were significantly higher in the patients who underwent the magnetic resonance imaging study more than 72 h (mean 120) after the acute event, suggesting increased acculumation of Gadolinium-DTPA in a more advanced stage of the infarction process. In Group IV (45 patients) Gadolinium-DTPA was administered in an attempt to distinguish between reperfused and nonreperfused myocardial areas after thrombolytic treatment for acute myocardial infarction. The signal intensities did not differ, but reperfused areas showed a more homogeneous aspect whereas nonreperfused areas were visualized as a more heterogeneous contrast enhancement. It is concluded that magnetic resonance imaging using the contrast agent Gadolinium-DTPA significantly improves the detection of infarcted myocardial areas

Statins could have physiologic properties that may beneift patients that have been diagnosed with various acute neurological diseases. This review aims tosummarize the literature pertaining to stain use in acute neurological disease such as subarachnoid hemorrhage, intracerebral hemorrhage (ICH), cerebral ischemia (CI), traumatic brain injury, status epilepticus and meningitis. The authors reviewed published abstracts and manuscripts pertaining to experimental and clinical trials relevant to statins in acute neurological disease. Although acute statin therapy in the setting of subarachnoid hemorrhage might reduce delayed cerebral ischemia and mortality, it should not be considered standard care at this time. Acute statins therapy has not demonstrated anybeneift yet folowing an ICH or CI. Acute statin withdrawal may worsen outcome in acute CI. Observational and case-control studies suggest that pretreatment with statin at time of onset may be associated with better outcomes. Even though preclinical studies have shown statins to have beneifcial effects, there has been no clinical evidence. In conclusion, current published studies have not shown that acute statin therapy has any beneifcal effects in acute neurologic diseases and therefore further large randomized clinical trials are needed.

To create acute pancreatitis condition experimentally in rats using cerulein, and to reveal histopathological effects in pancreatic tissue with erdosteine. An experimental study. Department of General Surgery, Duzce University, Turkey, from June to October 2014. Thirty male Wistar albino rats were divided into three groups. No procedures were applied to Group 1. The rats in Group 2 and Group 3 were injected cerulein, to establish an experimental pancreatitis model and the blood amylase and lipase values were examined. The rats in Group 3 were given 10 mg/kg erdosteine. This treatment was continued for another 2 days and the rats were sacrificed. The pancreatic tissues were examined histopathologically for edema, inflammation, acinar necrosis, fat necrosis, and vacuolization. The lipase and amylase values and the histopathological examination of pancreatic tissues evidenced that the experimental acute pancreatitis model was established and edema, inflammation, acinar necrosis, fat necrosis, and vacuolization were observed in the pancreatic tissues. The statistical results suggest that erdosteine can decrease the edema, inflammation, acinar necrosis, fat necrosis and vacuolization scores in the tissues. The severity of acute pancreatitis, induced by cerulein in rats, is reduced with the use of erdosteine.

Objective: To analyze the CT appearance of acute appendicitis and investigate diagnostic value of MSCT on acute appendicitis. Methods: The type and CT appearance of 15 cases with acute appendicitis proved by surgery and histopathology or clinic was analyzed retrospectively. Multi-stages scanning was carried out on the whole abdomen with 16 row CT. Post processing techniques including MPR, CPR and MIP were performed to observe the lesions. Results: There were 3 acute suppurative appendicitis, 12 acute gangrene and perforative appendicitis and appendiceal abscess. Complication occurred in 10 cases with gangrene and perforative appendix or appendix molten. The complication included 4 pelvic abscess, 3 intra-abdminal abscess, 1 combined pelvic and intra-abdominal abscess, 4 conglutination bowel obstruction, 1 ureteritis stegnosis and 1 abdominal wall fistulae. The exact ratio of CT diagnosis on acute suppurative appendicitis and appendiceal abscess reached 93.3% preoperatively. It is difficult to distinguish between acute suppurative appendicitis and acute gangrenous appendicitis without perforation. Conclusion: The MSCT appearance of acute appendicitis was marked and of important value on diagnosis of acute appendicitis. (authors)

Acute heart failure and/or cardiogenic shock are frequently triggered by ischemic coronary events. Yet, there is a paucity of randomized data on the management of patients with heart failure complicating acute coronary syndrome, as acute coronary syndrome and cardiogenic shock have frequently been defined as exclusion criteria in trials and registries. As a consequence, guideline recommendations are mostly driven by observational studies, even though these patients have a particularly poor prognosis compared to heart failure patients without signs of coronary artery disease. In acute heart failure, and especially in cardiogenic shock related to ischemic conditions, vasopressors and inotropes are used. However, both pathophysiological considerations and available clinical data suggest that these treatments may have disadvantageous effects. The inodilator levosimendan offers potential benefits due to a range of distinct effects including positive inotropy, restoration of ventriculo-arterial coupling, increases in tissue perfusion, and anti-stunning and anti-inflammatory effects. In clinical trials levosimendan improves symptoms, cardiac function, hemodynamics, and end-organ function. Adverse effects are generally less common than with other inotropic and vasoactive therapies, with the notable exception of hypotension. The decision to use levosimendan, in terms of timing and dosing, is influenced by the presence of pulmonary congestion, and blood pressure measurements. Levosimendan should be preferred over adrenergic inotropes as a first line therapy for all ACS-AHF patients who are under beta-blockade and/or when urinary output is insufficient after diuretics. Levosimendan can be used alone or in combination with other inotropic or vasopressor agents, but requires monitoring due to the risk of hypotension. Copyright © 2016 The Authors.

Background. Acute appendicitis is a leading cause of the abdominal pain in children that need an urgent surgical treatment. Neither of individually clinical variables doesn't have a real discriminational nor predictive strength to be used as the only diagnostic test. A goal of this study is to define ultrasound criteria of the acute appendicitis by appointing of ultrasound parameters for this pathological condition, determine the relation between ultrasound signs and pathohistological finding, determine the connection of several ultrasound signs with a degree of the inflammation of the acute appendicitis. Methods. In the prospective study with an ultrasound method we examine 50 patients with clinical signs of the acute abdomen. In these patients, the sonographic diagnosis is confirmed by the surgical finding, in fact with a pathohistological diagnosis. A basic, positive sonograph finding of the acute appendicitis was the identification of tubular, noncompresive, aperistaltic bowel which demonstrates a connection with coecum and blind terminal. In our work we analysed the lasting of the symptoms until the hospital intervention in patients stratified according to the pathohistological finding. We used ultrasound equipment- Toshiba Sonolayer with convex 3.75 MHz and linear 8 MHz probes. Results. From 8 ultrasound signs of the acute appendicitis, only an anterior-posterior (AP) diameter of appendices, FAT (width of periappendicular fat tissue) and a peristaltic absence are positive ultrasound signs of the acute appendicitis. Appendicitis phlegmonosa is the most common pathohistological finding in our study (44%). Perforate gangrenous appendicitis and gangrenous appendicitis are represented in more than half of patients (30% + 22%), which suggests a long period of persisting symptoms until a hospital treatment. A statistic analysis shows a great possibility for using values of AP diameter, width of periapendicular fat tissue, just like the values of mural thickness in

For stroke patients, intensive nutritional management is an important and effective component of inpatient rehabilitation. Accordingly, acute care hospitals must detect and prevent malnutrition at an early stage. Blood transthyretin levels are widely used as a nutritional monitoring index in critically ill patients. Here, we had analyzed the relationship between the transthyretin levels during the acute phase and Functional Independence Measure in stroke patients undergoing convalescent rehabilitation. We investigated 117 patients who were admitted to our hospital with acute ischemic or hemorrhagic stroke from February 2013 to October 2015 and subsequently transferred to convalescent hospitals after receiving acute treatment. Transthyretin concentrations were evaluated at 3 time points as follows: at admission, and 5 and 10 days after admission. After categorizing patients into 3 groups according to the minimum transthyretin level, we analyzed the association between transthyretin and Functional Independence Measure. In our patients, transthyretin levels decreased during the first 5 days after admission and recovered slightly during the subsequent 5 days. Notably, Functional Independence Measure efficiency was significantly associated with the decrease in transthyretin levels during the 5 days after admission. Patients with lower transthyretin levels had poorer Functional Independence Measure outcomes and tended not to be discharged to their own homes. A minimal transthyretin concentration (stroke patients undergoing convalescent rehabilitation. In particular, an early decrease in transthyretin levels suggests restricted rehabilitation efficiency. Accordingly, transthyretin levels should be monitored in acute stroke patients to indicate mid-term rehabilitation prospects. Copyright © 2017 National Stroke Association. Published by Elsevier Inc.

Facebook remains the most widely used social media platform. Research suggests that Facebook may both enhance and undermine psychosocial constructs related to well-being, and that it may impair physiological stress recovery. However, little is known about its influence on stress reactivity. Using novel experimental methods, this study examined how Facebook influences reactivity to an acute social stressor. Facebook users (n=104, 53 males, mean age 19.50, SD=1.73) were randomly assigned to use their own Facebook account or sit quietly with the option of reading electronic magazines before experiencing an acute social stressor. All participants showed significant changes in subjective and physiological stress markers in response to the stressor. However, participants who used Facebook experienced lower levels of psychosocial stress, physiological stress, and rated the stressor as less threatening (p'sFacebook use may buffer stress-in particular psychosocial stress-if used before experiencing an acute social stressor.

Assess clinical and serological data as parameters indicative of a possible evolution to endocarditis after an episode of acute Q fever. Retrospective cohort study of evolution to endocarditis after an acute Q fever episode, analyzing the clinical and serological evolution and the antibiotic treatment administered. Eighty patients were recruited, 20% of whom had phase i IgG antibody levels ≥ 1:1024 in the first 3 months. Only 44% of the patients underwent antibiotherapy in the acute phase; only 2 patients underwent extended antibiotherapy. Fifteen percent of the patients underwent an echocardiogram. None of the patients had symptoms suggestive of chronic infection or progressed to endocarditis after a median follow-up of 100 months, regardless of the early increase in phase i IgG antibodies. The early increase in phase i IgG antibodies in asymptomatic patients is not associated with progression to endocarditis despite not undergoing prolonged antibiotic treatment.

Acute myocardial infarction after heart irradiation in young patients with Hodgkin's disease

International Nuclear Information System (INIS)

Joensuu, H.

1989-01-01

Forty-seven patients younger than 40 years at the time of the diagnosis, and irradiated to the mediastinum for Hodgkin's disease at Turku University Central Hospital from 1977 to 1982, were regularly followed for 56 to 127 months after therapy. Two patients developed an acute myocardial infarction ten and 50 months after cardiac irradiation at the age of only 28 and 24 years, respectively. None of the patients died from lymphoma within five years from the diagnosis, but one of the infarctions was eventually fatal. Since acute myocardial infarction is rare in this age group, the result suggests strongly that prior cardiac irradiation is a risk factor for acute myocardial infarction. The possibility of radiation-induced myocardial infarction should be taken into account both in treatment planning and follow-up of patients with Hodgkin's disease

Source water assessment and nonpoint sources of acutely toxic contaminants: A review of research related to survival and transport of Cryptosporidium parvum

Science.gov (United States)

Walker, Mark J.; Montemagno, Carlo D.; Jenkins, Michael B.

1998-12-01

Amendments to the Safe Drinking Water Act (PL-930123) in 1996 required that public water supply managers identify potential sources of contamination within contributing areas. Nonpoint sources of acutely toxic microbial contaminants, such as Cryptosporidium parvum, challenge current approaches to source identification and management as a first step toward developing management plans for public water supply protection. Little may be known about survival and transport in the field environment, prescribed practices may not be designed to manage such substances, and infective stages may be present in vast numbers and may resist water treatment and disinfection processes. This review summarizes research related to survival and transport of C. parvum oocysts, as an example of an acutely toxic contaminant with nonpoint sources in animal agriculture. It discusses ∥1) significance of infected domesticated animals as potential sources of C. parvum, (2) laboratory and field studies of survival and transport, and (3) approaches to source control in the context of public health protection.

Cernan, Martin; Szotkowski, Tomas; Pikalova, Zuzana

2017-09-01

Mixed-phenotype acute leukemia (MPAL) is a heterogeneous group of hematopoietic malignancies in which blasts show markers of multiple developmental lineages and cannot be clearly classified as acute myeloid or lymphoblastic leukemias. Historically, various names and classifications were used for this rare entity accounting for 2-5% of all acute leukemias depending on the diagnostic criterias used. The currently valid classification of myeloid neoplasms and acute leukemia published by the World Health Organization (WHO) in 2016 refers to this group of diseases as MPAL. Because adverse cytogenetic abnormalities are frequently present, MPAL is generally considered a disease with a poor prognosis. Knowledge of its treatment is limited to retrospective analyses of small patient cohorts. So far, no treatment recommendations verified by prospective studies have been published. The reported data suggest that induction therapy for acute lymphoblastic leukemia followed by allogeneic hematopoietic cell transplantation is more effective than induction therapy for acute myeloid leukemia or consolidation chemotherapy. The establishment of cooperative groups and international registries based on the recent WHO criterias are required to ensure further progress in understanding and treatment of MPAL. This review summarizes current knowledge on the diagnosis, classification, prognosis and treatment of MPAL patients.

Nonacetaminophen Drug-Induced Acute Liver Failure.

Thomas, Arul M; Lewis, James H

2018-05-01

Acute liver failure of all causes is diagnosed in between 2000 and 2500 patients annually in the United States. Drug-induced acute liver failure is the leading cause of acute liver failure, accounting for more than 50% of cases. Nonacetaminophen drug injury represents 11% of all cases in the latest registry from the US Acute Liver Failure Study Group. Although rare, acute liver failure is clinically dramatic when it occurs, and requires a multidisciplinary approach to management. In contrast with acetaminophen-induced acute liver failure, non-acetaminophen-induced acute liver failure has a more ominous prognosis with a lower liver transplant-free survival.

Full Text Available Abstract Background Since the 9/11 attack and severe acute respiratory syndrome (SARS, the development of qualified and able public health leaders has become a new urgency in building the infrastructure needed to address public health emergencies. Although previous studies have reported that the training of individual leaders is an important approach, the systemic and scientific training model need further improvement and development. The purpose of this study was to develop, deliver, and evaluate a participatory leadership training program for emergency response. Methods Forty-one public health leaders (N = 41 from five provinces completed the entire emergency preparedness training program in China. The program was evaluated by anonymous questionnaires and semi-structured interviews held prior to training, immediately post-training and 12-month after training (Follow-up. Results The emergency preparedness training resulted in positive shifts in knowledge, self-assessment of skills for public health leaders. More than ninety-five percent of participants reported that the training model was scientific and feasible. Moreover, the response of participants in the program to the avian influenza outbreak, as well as the planned evaluations for this leadership training program, further demonstrated both the successful approaches and methods and the positive impact of this integrated leadership training initiative. Conclusion The emergency preparedness training program met its aims and objectives satisfactorily, and improved the emergency capability of public health leaders. This suggests that the leadership training model was effective and feasible in improving the emergency preparedness capability.

Management of acute pancreatitis in children.

Abu-El-Haija, Maisam; Lin, Tom K; Nathan, Jaimie D

2017-10-01

Pediatric acute pancreatitis has been on the rise in the last decades, with an incidence close to adult pancreatitis. In the majority of cases acute pancreatitis resolves spontaneously, but in a subset of children the disease progresses to severe acute pancreatitis with attendant morbidity and mortality. Pediatric acute pancreatitis in this era is recognized as a separate entity from adult acute pancreatitis given that the causes and disease outcomes are different. There are slow but important advances made in understanding the best management for acute pancreatitis in children from medical, interventional, and surgical aspects. Supportive care with fluids, pain medications, and nutrition remain the mainstay for acute pancreatitis management. For complicated or severe pancreatitis, specialized interventions may be required with endoscopic or drainage procedures. Surgery has an important but limited role in pediatric acute pancreatitis.

2012-01-01

Full Text Available Background/Aim. Saliva is a body fluid which, like serum, can be used for determination of concentrations of certain drugs, both in pharmacotherapy as well as in acute poisonings. The aim of this study was to determine carbamazepine concentrations in both saliva and serum in acute poisoning in order to show if there is a correlation between the obtained values, as well as to monitor toxicokinetics of carbamazepine in body fluides. Methods. Saliva and serum samples were obtained from 26 patients treated with carbamazepine and 20 patients acutely poisoned by the drug immediately after their admission in the Emergency Toxicology Unit. Determination of salivary and serum carbamazepine concentrations was performed by the validated high pressure liquid chromatographyultraviolet (HPLC-UV method. Results. A significant correlation of salivary and serum carbamazepine concentrations in both therapeutic application and acute poisoning (r = 0.9481 and 0.9117, respectively was confirmed. In acute poisonings the mean ratio between salivary and serum concentrations of carbamazepine (0.43 was similar to the mean ratio after its administration in therapeutic doses (0.39, but there were high inter-individual variations in carbamazepine concentrations in the acutely poisoned patients, as a consequence of different ingested doses of the drug. In acute poisoning the halftime of carbamazepine in saliva and serum was 12.57 h and 6.76 h, respectively. Conclusion. Our results suggest a possible use of saliva as an alternative biological material for determination of carbamazepine concentrations in therapeutic application and acute poisoning as well, and a possible extrapolation of the results obtained in saliva to serum concentrations of carbamazepine.

Cranial computerized tomography in children suffering from acute leukemia

International Nuclear Information System (INIS)

Metz, O.

1981-01-01

Cranial computerized (axial) tomography permits a more complete neurologic supervision of children with acute leukemia and a better knowledge of the frequency and varieties of cerebral complications in leukemia. Endocranial complications in acute leukemia are essentially infiltrative, hemorrhagic, infectious or iatrogenic. Cranial computerized tomography can demonstrate cerebral changes in meningeal leukemia, hemorrhages, calcifications, brain atrophy or leukencephalopathy. The preliminary results of cranial computerized tomography in childhood leukemia suggest that the iatrogenic main lesion of the brain due to combined radiation-chemotherapy is atrophy whereas that of the intrathecal cytostatic therapy is demyelination. Accurate diagnostics and control of possible cerebral complications in therapy of leukemia is essentially for appropriate therapeutic management. For that cranial computerized tomography is the best method to a effective supervision of the brain. (author)

Genetic variation within hepatitis B surface antigen (HBsAg), in particular within the major hydrophobic region (MHR), is related to immune/vaccine and test failures and can have a significant impact on the vaccination and diagnosis of acute infection. This study shows, for the first time, variation among acute cases and compares the amino acid variation within the HBsAg between acute and chronic infections. We analyzed the virus isolated from 1231 acute and 585 chronic cases reported to an anonymized public health surveillance database between 2004 and 2014 in The Netherlands. HBsAg analysis revealed the circulation of 6 genotypes (Gt); GtA was the dominant genotype followed by GtD among both acute (68.2% and 17.4%, respectively) and chronic (34.9% and 34.2%, respectively) cases. Variation was the highest among chronic strains compared to that among acute strains. Both acute and chronic GtD showed the highest variation compared to that of other genotypes (P < .01). Substitutions within the MHR were found in 8.5% of the acute strains and 18.6% of the chronic strains. Specific MHR substitutions described to have an impact on vaccine/immune escape and/or HBsAg test failure were found among 4.1% of the acute strains and 7.0% of the chronic strains. In conclusion, we show a high variation of HBsAg among acute and chronic hepatitis B virus-infected cases in The Netherlands, in particular among those infected with GtD, and compare, for the first time, variation in frequencies between acute and chronic cases. Additional studies on the impact of these variations on vaccination and test failure need to be conducted, as well as whether HBsAg false-negative variants have been missed. © 2018 The Authors.

Public reporting of percutaneous coronary intervention (PCI) outcomes may create disincentives for physicians to provide care for critically ill patients, particularly at institutions with worse clinical outcomes. We thus sought to evaluate the procedural management and in-hospital outcomes of patients treated for acute myocardial infarction before and after a hospital had been publicly identified as a negative outlier. Using state reports, we identified hospitals that were recognized as negative PCI outliers in 2 states (Massachusetts and New York) from 2002 to 2012. State hospitalization files were used to identify all patients with an acute myocardial infarction within these states. Procedural management and in-hospital outcomes were compared among patients treated at outlier hospitals before and after public report of outlier status. Patients at nonoutlier institutions were used to control for temporal trends. Among 86 hospitals, 31 were reported as outliers for excess mortality. Outlier facilities were larger, treating more patients with acute myocardial infarction and performing more PCIs than nonoutlier hospitals ( P fashion (interaction P =0.50) after public report of outlier status. The likelihood of in-hospital mortality decreased at outlier institutions (RR, 0.83; 95% CI, 0.81-0.85) after public report, and to a lesser degree at nonoutlier institutions (RR, 0.90; 95% CI, 0.87-0.92; interaction P <0.001). Among patients that underwent PCI, in-hospital mortality decreased at outlier institutions after public recognition of outlier status in comparison with prior (RR, 0.72; 9% CI, 0.66-0.79), a decline that exceeded the reduction at nonoutlier institutions (RR, 0.87; 95% CI, 0.80-0.96; interaction P <0.001). Large hospitals with higher clinical volume are more likely to be designated as negative outliers. The rates of percutaneous revascularization increased similarly at outlier and nonoutlier institutions after report of outlier status. After outlier

Public health implications of wireless technologies.

Global exposures to emerging wireless technologies from applications including mobile phones, cordless phones, DECT phones, WI-FI, WLAN, WiMAX, wireless internet, baby monitors, and others may present serious public health consequences. Evidence supporting a public health risk is documented in the BioInitiative Report. New, biologically based public exposure standards for chronic exposure to low-intensity exposures are warranted. Existing safety standards are obsolete because they are based solely on thermal effects from acute exposures. The rapidly expanding development of new wireless technologies and the long latency for the development of such serious diseases as brain cancers means that failure to take immediate action to reduce risks may result in an epidemic of potentially fatal diseases in the future. Regardless of whether or not the associations are causal, the strengths of the associations are sufficiently strong that in the opinion of the authors, taking action to reduce exposures is imperative, especially for the fetus and children. Such action is fully compatible with the precautionary principle, as enunciated by the Rio Declaration, the European Constitution Principle on Health (Section 3.1) and the European Union Treaties Article 174.

Transmission of severe acute respiratory syndrome in dynamical small-world networks

Masuda, Naoki; Konno, Norio; Aihara, Kazuyuki

2004-03-01

The outbreak of severe acute respiratory syndrome (SARS) is still threatening the world because of a possible resurgence. In the current situation that effective medical treatments such as antiviral drugs are not discovered yet, dynamical features of the epidemics should be clarified for establishing strategies for tracing, quarantine, isolation, and regulating social behavior of the public at appropriate costs. Here we propose a network model for SARS epidemics and discuss why superspreaders emerged and why SARS spread especially in hospitals, which were key factors of the recent outbreak. We suggest that superspreaders are biologically contagious patients, and they may amplify the spreads by going to potentially contagious places such as hospitals. To avoid mass transmission in hospitals, it may be a good measure to treat suspected cases without hospitalizing them. Finally, we indicate that SARS probably propagates in small-world networks associated with human contacts and that the biological nature of individuals and social group properties are factors more important than the heterogeneous rates of social contacts among individuals. This is in marked contrast with epidemics of sexually transmitted diseases or computer viruses to which scale-free network models often apply.

Full Text Available Abstract Objectives: to describe the clinical characteristics and outcomes of acute community acquired pneumonia in children at a reference public hospital in Pernambuco State, Brazil (2010-2011 Methods: pneumonia case series of 80 children aged 28 days to 14 years old at Hospital da Restauração in Pernambuco, Brazil, from 2010 to 2011. Information was noted from medical files, and two comparison groups were created according to the severity of the disease, considering the presence of pleural effusion. Fisher or Mann-Whitney tests were used for comparative analyses. Results: severe pneumonia with pleural effusion was more frequent in children under five years of age (p=0,025, and was associated with longer period of fever (19 x 15 days and coughing (17 x 13 days, when compared to non-complicated pneumonia cases. Six children (7,5%, 6/80 died, 50% before the fourth day of hospitalization (p=0,001. All deaths were from the pleural effusion group in children from the countryside (p=0,026. Conclusions: the severity of pneumonia in children attended at this hospital is related to younger children, and those transferred from the health units in the countryside, so, early diagnosis and medical intervention are limited by infrastructure and available resources for the health.

Soluble Receptor for Advanced Glycation End Product: A Biomarker for Acute Coronary Syndrome

2015-01-01

Full Text Available The receptor of advanced glycation end products (RAGE and its ligands are linked to the pathogenesis of coronary artery disease (CAD, and circulating soluble receptor of advanced glycation end products (sRAGE, reflecting the RAGE activity, is suggested as a potential biomarker. Elevated sRAGE levels are reported in relation to acute ischemia and this review focuses on the role of sRAGE as a biomarker for the acute coronary syndrome (ACS. The current studies demonstrated that sRAGE levels are elevated in relation to ACS, however during a very narrow time period, indicating that the time of sampling needs attention. Interestingly, activation of RAGE may influence the pathogenesis and reflection in sRAGE levels in acute and stable CAD differently.

Abdominal Aortic Dissection with Acute Mesenteric Ischemia in a Patient with Marfan Syndrome

Directory of Open Access Journals (Sweden)

Chii-Shyan Lay

2006-07-01

Full Text Available Marfan syndrome is an autosomal dominant inherited disorder of connective tissue, with various complications manifested primarily in the cardiovascular system. It potentially leads to aortic dissection and rupture, these being the major causes of death. We report a patient who complained of acute abdominal pain, which presented as acute mesenteric ischemia combined with abdominal aortic dissection. Echocardiography showed enlargement of the aortic root and mitral valve prolapse. Abdominal computed tomography scan revealed acute mesenteric ischemia due to abdominal aortic dissection. Finally, the patient underwent surgery of aortic root replacement and had a successful outcome. Therefore, we suggest that for optimal risk assessment and monitoring of patients with Marfan syndrome, both aortic stiffness and the diameter of the superior mesenteric vein compared with that of the superior mesenteric artery are useful screening methods to detect acute mesenteric ischemia secondary to abdominal aortic dissection. Early diagnosis and early treatment can decrease the high mortality rate of patients with Marfan syndrome.

Major trauma is a leading cause of morbidity and mortality worldwide with hemorrhage accounting for 40% of deaths. Acute traumatic coagulopathy exacerbates bleeding, but controversy remains over the degree to which inhibition of procoagulant pathways (anticoagulation), fibrinogen loss, and fibrinolysis drive the pathologic process. Through a combination of experimental study in a murine model of trauma hemorrhage and human observation, the authors' objective was to determine the predominant pathophysiology of acute traumatic coagulopathy. First, a prospective cohort study of 300 trauma patients admitted to a single level 1 trauma center with blood samples collected on arrival was performed. Second, a murine model of acute traumatic coagulopathy with suppressed protein C activation via genetic mutation of thrombomodulin was used. In both studies, analysis for coagulation screen, activated protein C levels, and rotational thromboelastometry (ROTEM) was performed. In patients with acute traumatic coagulopathy, the authors have demonstrated elevated activated protein C levels with profound fibrinolytic activity and early depletion of fibrinogen. Procoagulant pathways were only minimally inhibited with preservation of capacity to generate thrombin. Compared to factors V and VIII, proteases that do not undergo activated protein C-mediated cleavage were reduced but maintained within normal levels. In transgenic mice with reduced capacity to activate protein C, both fibrinolysis and fibrinogen depletion were significantly attenuated. Other recognized drivers of coagulopathy were associated with less significant perturbations of coagulation. Activated protein C-associated fibrinolysis and fibrinogenolysis, rather than inhibition of procoagulant pathways, predominate in acute traumatic coagulopathy. In combination, these findings suggest a central role for the protein C pathway in acute traumatic coagulopathy and provide new translational opportunities for management of

Oxytocin (OT) is known to be involved in anxiety, as well as cardiovascular and hormonal regulation. The objective of this study was to assess the acute effect of intranasally administered OT on subjective states, as well as cardiovascular and endocrine parameters, in healthy volunteers (n = 14) performing a simulated public speaking test. OT or placebo was administered intranasally 50 min before the test. Assessments were made across time during the experimental session: (1) baseline (-30 min); (2) pre-test (-15 min); (3) anticipation of the speech (50 min); (4) during the speech (1:03 h), post-test time 1 (1:26 h), and post-test time 2 (1:46 h). Subjective states were evaluated by self-assessment scales. Cortisol serum and plasma adrenocorticotropic hormone (ACTH) were measured. Additionally, heart rate, blood pressure, skin conductance, and the number of spontaneous fluctuations in skin conductance were measured. Compared with placebo, OT reduced the Visual Analogue Mood Scale (VAMS) anxiety index during the pre-test phase only, while increasing sedation at the pre-test, anticipation, and speech phases. OT also lowered the skin conductance level at the pre-test, anticipation, speech, and post-test 2 phases. Other parameters evaluated were not significantly affected by OT. The present results show that OT reduces anticipatory anxiety, but does not affect public speaking fear, suggesting that this hormone has anxiolytic properties.

Acute colorectal surgery forms a significant proportion of emergency admissions within the National Health Service. There is limited evidence to suggest minimally invasive surgery may be associated with improved clinical outcomes in this cohort of patients. Consequently, there is a need to assess the clinical effectiveness and cost-effectiveness of laparoscopic surgery in the acute colorectal setting. However,emergency colorectal surgical trials have previously been difficult to conduct due to issues surrounding recruitment and equipoise. The LaCeS (randomised controlled trial of Laparoscopic versus open Colorectal Surgery in the acute setting) feasibility trial will determine the feasibility of conducting a definitive, phase III trial of laparoscopic versus open acute colorectal resection. The LaCeS feasibility trial is a prospective, multicentre, single-blinded, parallel group, pragmatic randomised controlled feasibility trial. Patients will be randomised on a 1:1 basis to receive eitherlaparoscopic or open surgery. The trial aims to recruit at least 66 patients from five acute general surgical units across the UK. Patients over the age of 18 with a diagnosis of acute colorectal pathology requiring resection on clinical and radiological/endoscopic investigations, with a National Confidential Enquiry into Patient Outcome and Death classification of urgent will be considered eligible for participation. The primary outcome is recruitment. Secondary outcomes include assessing the safety profile of laparoscopic surgery using intraoperative and postoperative complication rates, conversion rates and patient-safety indicators as surrogate markers. Clinical and patient-reported outcomes will also be reported. The trial will contain an embedded qualitative study to assess clinician and patient acceptability of trial processes. The LaCeS feasibility trial is approved by the Yorkshire and The Humber, Bradford Leeds Research Ethics Committee (REC reference: 15/ YH/0542). The

To compare the quality of care-using unplanned acute hospital readmissions as a quality measure-among patients treated at private for-profit hospitals (PFPs), private non-profit hospitals (PNPs) and public hospitals (PUBs) in Norway. A retrospective comparative study using the Norwegian Patient Register. Readmissions were evaluated by logistic regressions both using adjustment for various patient-level and other covariates, and a two-stage model using distance as an instrumental variable. The Norwegian healthcare system. All publicly financed patients having primary total hip (37 897 patients) or primary total knee arthroplasty (25 802 patients) at one of the three hospital types from 2009 to 2014. 30-day unplanned acute hospital readmission rate. We found highest readmission rates among PUBs and lowest among PFPs, for both procedures. However, the patients were on average more than 2 years younger at PFPs. PFPs also treated the least severe patients, while PUBs treated the most severe. Using adjustment for various patient-level and other covariates, compared to PUBs, both PFPs and PNPs had lower odds of readmission following both procedures. However, using the instrumental variable method, the only significant difference found was a lower odds of readmission at PNPs among hip patients when compared with PUBs. No patients in our data set were readmitted to PFPs, those originally treated at PFPs were readmitted to either PNPs or PUBs, and PUBs received most of the readmitted patients across hospital types. Quality differences between hospital types were small; however, PNPs had significantly lower readmission rates compared with PUBs among patients having total hip arthroplasty. PUBs received the larger part of the readmitted patients across hospital types and thus play an essential role in the care of more complex patients and for readmissions, regardless of any quality differences. © Article author(s) (or their employer(s) unless otherwise stated in the

Anxiety and stress disorders have been linked to deficits in fear extinction. Our laboratory and others have demonstrated that acute nicotine impairs contextual fear extinction, suggesting that nicotine exposure may have negative effects on anxiety and stress disorder symptomatology. However, the neurobiological mechanisms underlying the acute nicotine-induced impairment of contextual fear extinction are unknown. Therefore, based on the previous studies showing that brain-derived neurotrophic factor is central for fear extinction learning and acute nicotine dysregulates brain-derived neurotrophic factor signaling, we hypothesized that the nicotine-induced impairment of contextual fear extinction may involve changes in tyrosine receptor kinase B signaling. To test this hypothesis, we systemically, intraperitoneally, injected C57BL/6J mice sub-threshold doses (2.5 and 4.0 mg/kg) of 7,8-dihydroxyflavone, a small-molecule tyrosine receptor kinase B agonist that fully mimics the effects of brain-derived neurotrophic factor, or vehicle an hour before each contextual fear extinction session. Mice also received injections, intraperitoneally, of acute nicotine (0.18 mg/kg) or saline 2-4 min before extinction sessions. While the animals that received only 7,8-dihydroxyflavone did not show any changes in contextual fear extinction, 4.0 mg/kg of 7,8-dihydroxyflavone ameliorated the extinction deficits in mice administered acute nicotine. Overall, these results suggest that acute nicotine-induced impairment of context extinction may be related to a disrupted brain-derived neurotrophic factor signaling.

Type B aortic dissection is a relatively uncommon and multifaceted disease, whose management is ongoing debated. Its wide range of clinical presentations and anatomical features hamper the early identification and medical management. In the past few years, the introduction of endovascular techniques opened new paradigms in comprehension and management of aortic diseases. Aim of this review is to discuss contemporary therapeutic approaches of acute type B aortic dissections highlighting the growing role of thoracic endovascular aortic repair (TEVAR) in focusing its complex physiopathology. Prompt medical therapy followed by endovascular repair should be considered as the gold standard in complicated acute type B aortic dissection. Moreover, recent findings also suggest a potential benefit in case of uncomplicated cases. Management of acute type B aortic dissection is progressively shifting into endovascular approach. However, further studies are warranted to define the optimal treatment strategy in each subset of patients and anatomical features.

In recent years, there has been increasing interest in the role of intravenous lipid formulations as potential antidotes in patients with severe cardiotoxicity caused by drug toxicity. The aim of this study was to conduct a comprehensive bibliometric analysis of all human and animal studies featuring lipid emulsion as an antidote for the treatment of acute poisoning. The Scopus database search was performed on 5 February 2016 to analyse the research output related to intravenous lipid emulsion as an antidote for the treatment of acute poisoning. Research indicators used for analysis included total number of articles, date (year) of publication, total citations, value of the h-index, document types, countries of publication, journal names, collaboration patterns and institutions. A total of 594 articles were retrieved from Scopus database for the period of 1955-2015. The percentage share of global intravenous lipid emulsion research output showed that research output was 85.86% in 2006-2015 with yearly average growth in this field of 51 articles per year. The USA, United Kingdom (UK), France, Canada, New Zealand, Germany, Australia, China, Turkey and Japan accounted for 449 (75.6%) of all the publications. The total number of citations for all documents was 9,333, with an average of 15.7 citations per document. The h-index of the retrieved documents for lipid emulsion research as antidote for the treatment of acute poisoning was 49. The USA and the UK achieved the highest h-indices, 34 and 14, respectively. New Zealand produced the greatest number of documents with international collaboration (51.9%) followed by Australia (50%) and Canada (41.4%) out of the total number of publications for each country. In summary, we found an increase in the number of publications in the field of lipid emulsion after 2006. The results of this study demonstrate that the majority of publications in the field of lipid emulsion were published by high-income countries. Researchers from

DNA methyltransferase 3A (DNMT3A) catalyzes de novo DNA methylation and plays important roles in the pathogenesis of acute myeloid leukemia. However, the expression status of DNMT3A variants in acute myeloid leukemia remains obscure. This study aimed to assess the expression levels of alternative splicing of DNMT3A variants and explore their roles in acute myeloid leukemia (AML). DNMT3A variants gene expression were assessed, measuring their effects on cell proliferation. In addition, the expression of DNMT3A variants were evaluated in acute myeloid leukemia patients. Four DNMT3A variants were identified, with DNMT3A1 and DNMT3A2V found to be dominant in acute myeloid leukemia cell lines. Moreover, DNMT3A2V overexpression delayed cell proliferation; while, DNMT3A2V R882H mutation promoted cell proliferation. Further, DNMT3A1 and DNMT3A2V were detected in newly diagnosed acute myeloid leukemia (AML) patients and controls with non-malignant hematological disease, with DNMT3A2V significantly up-regulated in AML patients. The main transcript switched from DNMT3A1 to DNMT3A2V in some patients, especially the low risk group based on the NCCN 2016 guidelines. These findings suggest that DNMT3A1 and DNMT3A2V are the main variants in acute myeloid leukemia with different clinical association, and might play important roles in the pathophysiology of acute myeloid leukemia.

Public attitudes toward nuclear risks and benefits

International Nuclear Information System (INIS)

Savellano, R.A.

As the world progresses in technology, public awareness of risks and benefits have become more acute. This is more so towards nuclear risks and benefits. This comes about when people throughout the world, because of the energy crisis, have accepted the nuclear option. Hand in hand with the benefits that it brings are the risks of radiation and other calamities. ''The role of information, the methods of public participation, and the involvement of scientific expertise play an important part in risk assessment.'' Interest in nuclear power has gained momentum with the announcement of the construction of the first nuclear power plant. Different reactions, brought about by economic, social, moral and political factors were evident, but the economic benefits seem to prevail. Nuclear power accidents, citing particularly the recent TMI incident, have started the hornets nest of nuclear controversies and have widened the scope of concern on nuclear power. The newspapers and the media, public meetings and hearings have been used as arenas of these conflicts. These brought about varying opinions and growing disagreement among the public. Risk assessment is therefore dependent on effective communication not only with the public but between scientists and decision makers and also individuals. Risk assessment in nuclear power is a complex undertaking which is to consider a wide spectrum of factors to come up with reliable results. (author)

The urgent need for a harmonized severity scoring system for acute allergic reactions

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...... 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...... 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...

Chlorine is a pulmonary toxicant to which humans can be exposed through accidents or intentional releases. Acute effects of chlorine inhalation in humans and animal models have been well characterized, but less is known about persistent effects of acute, high-level chlorine exposures. In particular, animal models that reproduce the long-term effects suggested to occur in humans are lacking. Here, we report the development of a rabbit model in which both acute and persistent effects of chlorine inhalation can be assessed. Male New Zealand White rabbits were exposed to chlorine while the lungs were mechanically ventilated. After chlorine exposure, the rabbits were extubated and were allowed to survive for up to 24 h after exposure to 800 ppm chlorine for 4 min to study acute effects or up to 7 days after exposure to 400 ppm for 8 min to study longer term effects. Acute effects observed 6 or 24 h after inhalation of 800 ppm chlorine for 4 min included hypoxemia, pulmonary edema, airway epithelial injury, inflammation, altered baseline lung mechanics, and airway hyperreactivity to inhaled methacholine. Seven days after recovery from inhalation of 400 ppm chlorine for 8 min, rabbits exhibited mild hypoxemia, increased area of pressure–volume loops, and airway hyperreactivity. Lung histology 7 days after chlorine exposure revealed abnormalities in the small airways, including inflammation and sporadic bronchiolitis obliterans lesions. Immunostaining showed a paucity of club and ciliated cells in the epithelium at these sites. These results suggest that small airway disease may be an important component of persistent respiratory abnormalities that occur following acute chlorine exposure. This non-rodent chlorine exposure model should prove useful for studying persistent effects of acute chlorine exposure and for assessing efficacy of countermeasures for chlorine-induced lung injury. - Highlights: • A novel rabbit model of chlorine-induced lung disease was developed. �

Full Text Available Barbara Okoniewska,1 Maria Jose Santana,1 Horacio Groshaus,2 Svetlana Stajkovic,3 Jennifer Cowles,4 David Chakrovorty,5 William A Ghali1 1Department of Community Health Sciences, W21C Research and Innovation Centre, Institute of Public Health, 2Department of Internal Medicine, University of Calgary, 3Community Based Practice, 4Foothills Medical Centre, 5Department of Quality and Healthcare Improvement, Alberta Health Services, Calgary, AB, Canada Background: The complex process of discharging patients from acute care to community care requires a multifaceted interaction between all health care providers and patients. Poor communication in a patient’s discharge can result in post hospital adverse events, readmission, and mortality. Because of the gravity of these problems, discharge planning has been emphasized as a potential solution. The purpose of this paper is to identify communication barriers to effective discharge planning in an acute care unit of a tertiary care center and to suggest solutions to these barriers. Methods: Health care providers provided comments to a single open-ended question: “What are the communication barriers between the different health care providers that limit an effective discharge of patients from Unit 36?” We conducted qualitative thematic analysis by identifying themes related to communication barriers affecting a successful discharge process. Results: Three broad themes related to barriers to the discharge process were identified: communication, lack of role clarity and lack of resources. We also identified two themes for opportunities for improvement, ie, structure and function of the medical team and need for leadership. Conclusion: While it was evident that poor communication was an overarching barrier identified by health care providers, other themes emerged. In an effort to increase inter-team communication, “bullet rounds”, a condensed form of discharge rounds, were introduced to the medical

Healthcare is increasingly delivered in a team-based format emphasizing interdisciplinary coordination. While recent reviews have investigated team-building interventions primarily in acute healthcare settings (e.g. emergency or surgery departments), we aimed to systematically review the evidence base for team-building interventions in non-acute settings (e.g. primary care or rehabilitation clinics). We conducted a systematic review in PubMed and Embase to identify team-building interventions, and conducted follow-up literature searches to identify articles describing empirical studies of those interventions. This process identified 14 team-building interventions for non-acute healthcare settings, and 25 manuscripts describing empirical studies of these interventions. We evaluated outcomes in four domains: trainee evaluations, teamwork attitudes/knowledge, team functioning, and patient impact. Trainee evaluations for team-building interventions were generally positive, but only one study associated team-building with statistically significant improvement in teamwork attitudes/knowledge. Similarly mixed results emerged for team functioning and patient impact. The evidence base for healthcare team-building interventions in non-acute healthcare settings is much less developed than the parallel literature for short-term team function in acute care settings. Only one intervention we identified has been tested in multiple non-acute settings by distinct research teams. Positive findings regarding the utility of team-building interventions are tempered by a lack of control conditions, inconsistency in outcome measures, and high probability of bias. Considering these results alongside the well-recognized costs of poor healthcare teamwork suggests that additional research is sorely needed to develop the evidence base for team-building in non-acute settings.

Full Text Available This is a case of a pregnant lady at 8 weeks of gestation, who presented with acute abdomen. She was initially diagnosed with ruptured ectopic pregnancy and ruptured corpus luteal cyst as the differential diagnosis. However she then, was finally diagnosed as acute hemorrhagic pancreatitis with spontaneous complete miscarriage. This is followed by review of literature on this topic. Acute pancreatitis in pregnancy is not uncommon. The emphasis on high index of suspicion of acute pancreatitis in women who presented with acute abdomen in pregnancy is highlighted. Early diagnosis and good supportive care by multidisciplinary team are crucial to ensure good maternal and fetal outcomes.

The role of dehydroepiandrosterone on functional innate immune responses to acute stress.

Science.gov (United States)

Prall, Sean P; Larson, Emilee E; Muehlenbein, Michael P

2017-12-01

The androgen dehydroepiandrosterone (DHEA) responds to stress activation, exhibits anti-glucocorticoid properties, and modulates immunity in diverse ways, yet little is known of its role in acute stress responses. In this study, the effects of DHEA and its sulfate ester DHEA-S on human male immune function during exposure to an acute stressor is explored. Variation in DHEA, DHEA-S, testosterone, and cortisol, along with bacterial killing assays, was measured in response to a modified Trier Social Stress test in 27 young adult males. Cortisol was positively related to salivary innate immunity but only for participants who also exhibited high DHEA responses. Additionally, DHEA positively and DHEA-S negatively predicted salivary immunity, but the opposite was observed for serum-based innate immunity. The DHEA response to acute stress appears to be an important factor in stress-mediated immunological responses, with differential effects on immunity dependent upon the presence of other hormones, primarily cortisol and DHEA-S. These results suggest that DHEA plays an important role, alongside other hormones, in modulating immunological shifts during acute stress. Copyright © 2017 John Wiley & Sons, Ltd.

Twelve patients with acute renal failure underwent L-dopa infusion into a renal artery and /sup 133/Xenon wash-out recordings before and during the infusion. Urine volume and sodium output were also compared during two 24 hours periods, before and after the procedure. Hemodynamic data were compared with data obtained from a matched group of patients receiving Furosemide (8 patients) in place of L-dopa. Only L-dopa infusion significantly increased outer cortical distribution. No blood flow change could be demonstrated in any component nor did the drug improve unitary excretion or the general course of the disease. Control data shows that reduced cortical distribution is the most consistent feature of acute renal failure, so that L-dopa does partially improve intrarenal hemodynamics in this condition. The failure of the drug to restore kidney function may be explained by the following reasons: inability of the agent to restore a normal wash-out pattern: involvment of non-hemodynamic factors, as suggested by comparing similar wash-out improvements after L-dopa in acute glomerulonephritis and in reversible acute renal failure.

2010-01-01

Full Text Available Zinc supplementation is recommended in all acute diarrheas in children from developing countries. We aimed to assess whether zinc supplementation would be equally effective against all the common organisms associated with acute diarrheas. We used data on 801 children with acute diarrhea recruited in a randomized, double blind controlled trial (ISRCTN85071383 of zinc and copper supplementation. Using prespecified subgroup analyses, multidimensionality reduction analyses, tests of heterogeneity, and stepwise logistic regression for tests of interactions, we found that the influence of zinc on the risk of diarrhea for more than 3 days depended on the isolated organism—beneficial in Klebsiella, neutral in Esherichia coli and parasitic infections, and detrimental in rotavirus coinfections. Although we found similar results for the outcome of high stool volume, the results did not reach statistical significance. Our findings suggest that the current strategy of zinc supplementation in all cases of acute diarrheas in children may need appropriate fine tuning to optimize the therapeutic benefit based on the causative organism, but further studies need to confirm and extend our findings.

We reviewed 27 cases in which the patient complained of acute neck pain. We had performed arthrocentesis of the atlanto-axial joint in every case. An aspirate was obtained in 16 of the cases, and calcium pryophosphate dihydrate (CPPD) crystals were demonstrated in 10 of them. The patients' scores on the visual analogue scale decreased 30 minutes after aspiration of the crystals (p<0.001). CT demonstrated calcification of the transverse ligament in 22 cases, calcification anterior to the body of C2 in 2 cases, and no calcification in 3 cases. The results in these patients suggest that acute neck pain in some elderly patients is related to arthritis of the atlanto-axial joint. (author)

Boehme, Amelia K.; Martin-Schild, Sheryl; Marshall, Randolph S.

2016-01-01

Objective: To determine the independent effects of aphasia on outcomes during acute stroke admission, controlling for total NIH Stroke Scale (NIHSS) scores and loss of consciousness. Methods: Data from the Tulane Stroke Registry were used from July 2008 to December 2014 for patient demographics, NIHSS scores, length of stay (LOS), complications (sepsis, deep vein thrombosis), and discharge modified Rankin Scale (mRS) score. Aphasia was defined as a score >1 on question 9 on the NIHSS on admission and hemiparesis as >1 on questions 5 or 6. Results: Among 1,847 patients, 866 (46%) had aphasia on admission. Adjusting for NIHSS score and inpatient complications, those with aphasia had a 1.22 day longer LOS than those without aphasia, whereas those with hemiparesis (n = 1,225) did not have any increased LOS compared to those without hemiparesis. Those with aphasia had greater odds of having a complication (odds ratio [OR] 1.44, confidence interval [CI] 1.07–1.93, p = 0.0174) than those without aphasia, which was equivalent to those having hemiparesis (OR 1.47, CI 1.09–1.99, p = 0.0137). Controlling for NIHSS scores, aphasia patients had higher odds of discharge mRS 3–6 (OR 1.42 vs 1.15). Conclusion: Aphasia is independently associated with increased LOS and complications during the acute stroke admission, adding $2.16 billion annually to US acute stroke care. The presence of aphasia was more likely to produce a poor functional outcome than hemiparesis. These data suggest that further research is necessary to determine whether establishing adaptive communication skills can mitigate its consequences in the acute stroke setting. PMID:27765864

Factor structure of suggestibility revisited: new evidence for direct and indirect suggestibility

Directory of Open Access Journals (Sweden)

Romuald Polczyk

2016-05-01

Full Text Available Background Yielding to suggestions can be viewed as a relatively stable individual trait, called suggestibility. It has been long proposed that there are two kinds of suggestible influence, and two kinds of suggestibility corresponding to them: direct and indirect. Direct suggestion involves overt unhidden influence, while indirect suggestion concerns influence that is hidden, and the participant does not know that the suggestibility is being measured. So far however, empirical evidence for the existence of the two factors has been scarce. In the present study, more sophisticated and reliable tools for measuring suggestibility were applied than in the previous research, in the hope that better measurement would reveal the factor structure of suggestibility. Two tests of direct suggestibility were used: the Harvard Group Scale of Hypnotic Susceptibility, Form A, measuring hypnotic susceptibility, and the Barber Suggestibility Scale, measuring non-hypnotic direct imaginative suggestibility. Three tests served to measure indirect suggestibility: the Sensory Suggestibility Scale, measuring indirect suggestibility relating to perception; the Gudjonsson Suggestibility Scale, measuring the tendency to yield to suggestive questions and changing answers after negative feedback; and the Emotional Dialogs Tests, measuring the tendency to perceive nonexistent aggression. Participants and procedure In sum, 115 participants were tested, 69 women, 49 men, mean age 22.20 years, SD = 2.20. Participants were tested in two sessions, lasting for a total of four hours. Results Confirmatory factor analyses confirmed the existence of two uncorrelated factors of suggestibility: direct and indirect. Conclusions Suggestibility may indeed involve two factors, direct and indirect, and failure to discover them in previous research may be due to methodological problems.

Vestibular perception following acute unilateral vestibular lesions.

Directory of Open Access Journals (Sweden)

Sian Cousins

Full Text Available Little is known about the vestibulo-perceptual (VP system, particularly after a unilateral vestibular lesion. We investigated vestibulo-ocular (VO and VP function in 25 patients with vestibular neuritis (VN acutely (2 days after onset and after compensation (recovery phase, 10 weeks. Since the effect of VN on reflex and perceptual function may differ at threshold and supra-threshold acceleration levels, we used two stimulus intensities, acceleration steps of 0.5°/s(2 and velocity steps of 90°/s (acceleration 180°/s(2. We hypothesised that the vestibular lesion or the compensatory processes could dissociate VO and VP function, particularly if the acute vertiginous sensation interferes with the perceptual tasks. Both in acute and recovery phases, VO and VP thresholds increased, particularly during ipsilesional rotations. In signal detection theory this indicates that signals from the healthy and affected side are still fused, but result in asymmetric thresholds due to a lesion-induced bias. The normal pattern whereby VP thresholds are higher than VO thresholds was preserved, indicating that any 'perceptual noise' added by the vertigo does not disrupt the cognitive decision-making processes inherent to the perceptual task. Overall, the parallel findings in VO and VP thresholds imply little or no additional cortical processing and suggest that vestibular thresholds essentially reflect the sensitivity of the fused peripheral receptors. In contrast, a significant VO-VP dissociation for supra-threshold stimuli was found. Acutely, time constants and duration of the VO and VP responses were reduced - asymmetrically for VO, as expected, but surprisingly symmetrical for perception. At recovery, VP responses normalised but VO responses remained shortened and asymmetric. Thus, unlike threshold data, supra-threshold responses show considerable VO-VP dissociation indicative of additional, higher-order processing of vestibular signals. We provide evidence of

Drinking status but not acute alcohol consumption influences delay discounting.

The aim of this study was to investigate the following: (a) the effects of acute alcohol on delay discounting; (b) the effects of drinking status on delayed discounting; and (c) whether these effects differ according to reward type (alcohol vs. money). Heavy and light social alcohol users (n = 96) were randomized to receive either an acute dose of alcohol at 0.4 or 0.6 g/kg or placebo in a between-subjects, double-blind design. Delay discounting of alcohol and monetary rewards was measured using a hyperbolic model, with higher scores indicative of greater delay discounting. ANOVA of discount scores indicated a main effect of reward type, where all participants had higher discount scores for alcohol versus money rewards. A main effect of drinking status was also observed, where heavier drinkers had higher discount scores compared with lighter drinkers. We did not observe a main effect of acute alcohol use on delay discounting or the hypothesized interactions between acute alcohol use and drinking status with reward type. Our data suggest that heavier drinkers discount the value of delayed rewards more steeply than lighter drinkers. Delay discounting may therefore be a promising marker of heavy alcohol consumption in social drinkers. Copyright © 2017 John Wiley & Sons, Ltd.

Acute infarction of corpus callosum due to transient obstructive hydrocephalus.

Kaymakamzade, Bahar; Eker, Amber

2016-01-01

Acute ischemia of the corpus callosum (CC) is not a well-known feature in patients with acute hydrocephalus. Herein, we describe a case with acute CC infarction due to another rare entity; transient obstructive hydrocephalus. A 66-year-old male was admitted with sudden onset right-sided hemiparesia. CT demonstrated a hematoma on the left basal ganglia with extension to all ventricles. The following day, the patient's neurological status progressed to coma and developed bilateral pyramidal signs. MRI demonstrated obstructive hydrocephalus and acute diffuse infarction accompanied by elevation of the CC. On the same day there was improvement in his neurological status with significant decrease in ventricular size and complete resolution of the clot in the third ventricle. The mechanism of signal abnormalities is probably related with the neural compression of the CC against the falx. Presumably, the clot causing obstruction in the third ventricle dissolved or decayed by the help of fibrinolytic activity of CSF, which was raised after IVH and caused spontaneous improvement of hydrocephalus. Bilateral neurological symptoms suggest diffuse axonal damage and normalization of the intracranial pressure should be performed on the early onset of clinical detorioration in order to prevent axonal injury.

The central responsiveness of the acute cerveau isolé rat.

User, P; Gottesmann, C

1982-01-01

The electrophysiological patterns of the frontal cortex and dorsal hippocampus were studied in the acute cerveau isolé rat. Central and peripheral stimulations were performed in order to modulate these patterns. The results showed that the permanent alternation of high amplitude spindle bursts and low voltage activity in the anterior neocortex of the acute cerveau isolé was influenced neither by olfactory nor by posterior hypothalamic stimulation. In contrast, these two kinds of stimulation easily modulated the continuous low frequency theta rhythm, recorded in the dorsal hippocampus, in terms of amplitude and in overall frequency. This modulation of the theta rhythm in the acute cerveau isolé rat mimics the changes observed when the normal rat comes from the intermediate stage of sleep (as characterized in the the acute intercollicular transected rat by high amplitude spindle bursts at frontal cortex level and low frequency theta activity in the dorsal hippocampus) to rapid sleep. These results further suggest that, during the intermediate stage (as in the cerveau isolé preparation), the hippocampus montonous theta activity appears through a brainstem disinhibitory process releasing the forebrain limbic pacemaker(s). During the following rapid sleep phase, the theta rhythm would be modulated by pontine activity influences acting on the theta generators.

There are limited case reports of structural lesions causing Korsakoff syndrome. This report describes acute Korsakoff syndrome following localized, bilateral infarction of the mammillothalamic tracts (MTTs). Axial T2-weighted imaging revealed the lesions at the lateral wall level of the third ventricle and diffusion-weighted imaging confirmed that the left lesion was new and the right old. Korsakoff syndrome persisted 6 months after the onset. This case suggests that bilateral MTT dysfunction can lead to Korsakoff syndrome.

Full Text Available LCZ696 (sacubitril/valsartan can lower the risk of cardiovascular events in chronic heart failure. However, it is unclear whether LCZ696 can improve prognosis in patients with acute myocardial infarction (MI. The present study shows that LCZ696 can prevent cardiac rupture after MI, probably due to the suppression of pro-inflammatory cytokines, matrix metalloproteinase-9 activity and aldosterone production, and enhancement of natriuretic peptides in mice. These findings suggest the mechanistic insight of cardioprotective effects of LCZ696 against acute MI, resulting in the belief that LCZ696 might be useful clinically to improve survival after acute MI.

To fulfill Food and Drug Administration and Department of Health and Human Services emergency care research informed consent requirements, our burn center planned and executed a deferred consent strategy gaining Institutional Review Board (IRB) approval to proceed with the clinical study. These federal regulations dictate public disclosure and community consultation unique to acute care research. Our regional burn center developed and implemented a deferred consent public notification and community consultation paradigm appropriate for a burn study. Published accounts of deferred consent strategies focus on acute care resuscitation practices. We adapted those strategies to design and conduct a comprehensive public notification/community consultation plan to satisfy deferred consent requirements for burn center research. To implement a robust media campaign we engaged the hospital's public relations department, distributed media materials, recruited hospital staff for speaking engagements, enlisted community volunteers, and developed initiatives to inform "hard-to-reach" populations. The hospital's IRB determined we fulfilled our obligation to notify the defined community. Our communication strategy should provide a paradigm other burn centers may appropriate and adapt when planning and executing a deferred consent initiative. Copyright © 2012 Elsevier Ltd and ISBI.

Leading Public Design

DEFF Research Database (Denmark)

Bason, Christian

at all levels have taken up a variety of approaches inspired by the field of design, often in response to growing pressures to innovate. But how these approaches influence public innovation – how they change the roles of public managers, how they help managers generate new ideas and solutions...... – and whether, as some have suggested, they might signal the rise of new governance models or paradigms – these issues have not, with perhaps a few exceptions, been rigorously explored. In this thesis, I explore these issues by examining the experiences of public managers who have pioneered the use of design...... approaches. More specifically, I confront three questions: • Characterizing design practice: Within public sector organizations, what does the application of design approaches entail? Why do public managers look to and commission design, and what tools, techniques, processes and methods are brought into play...

Guillain-Barré syndrome and acute transverse myelitis manifest as demyelinating diseases of the peripheral and central nervous system. Concurrency of these two disorders is rarely documented in literature. A 4-year-old girl presenting with cough, fever, and an impaired walking ability was admitted to hospital. She had no previous complaints in her medical history. A physical examination revealed lack of muscle strength of the lower extremities and deep tendon reflexes. MRI could not be carried out due to technical problems; therefore, both Guillain-Barré syndrome and acute transverse myelitis were considered for the diagnosis. Intravenous immunoglobulin treatment was started as first line therapy. Because this treatment did not relieve the patient's symptoms, spinal MRI was carried out on the fourth day of admission and demyelinating areas were identified. Based on the new findings, the patient was diagnosed with acute transverse myelitis, and high dose intravenous methylprednisolone therapy was started. Electromyography findings were consistent with acute polyneuropathy affecting both motor and sensory fibers. Therefore, the patient was diagnosed with concurrency of Guillain-Barré syndrome and acute transverse myelitis. Interestingly, while concurrency of these 2 disorders is rare, this association has been demonstrated in various recent publications. Progress in diagnostic tests (magnetic resonance imaging and electrophysiological examination studies) has enabled clinicians to establish the right diagnosis. The possibility of concurrent Guillain-Barré syndrome and acute transverse myelitis should be considered if recovery takes longer than anticipated.

Full Text Available Every year, more information accumulates about the possibility of treating patients with acute lung injury or acute respiratory distress syndrome with specially designed mechanical ventilation strategies. Ventilator modes, positive end-expiratory pressure settings, and recruitment maneuvers play a major role in these strategies. However, what can we take from these experimental and clinical data to the clinical practice? In this article, we discuss substantial options of mechanical ventilation together with some adjunctive therapeutic measures, such as prone positioning and inhalation of nitric oxide.

Factor structure of suggestibility revisited: new evidence for direct and indirect suggestibility

OpenAIRE

2016-01-01

Background Yielding to suggestions can be viewed as a relatively stable individual trait, called suggestibility. It has been long proposed that there are two kinds of suggestible influence, and two kinds of suggestibility corresponding to them: direct and indirect. Direct suggestion involves overt unhidden influence, while indirect suggestion concerns influence that is hidden, and the participant does not know that the suggestibility is being measured. So far however, empirical evidence ...

Metachronous primary distinct tumors are frequently and increasingly encountered in oncology clinical practice of recent times, but synchronous tumours are still a rarity. We report an unusual case of a 2 year old male child who had synchronous occurrence of rhabdomyosarcoma of pelvis and acute myeloid leukemia.Our search of literature suggests that this may be the first reported case of simultaneous occurrence of these two malignancies.

RNAi mediated acute depletion of Retinoblastoma protein (pRb promotes aneuploidy in human primary cells via micronuclei formation

Full Text Available Abstract Background Changes in chromosome number or structure as well as supernumerary centrosomes and multipolar mitoses are commonly observed in human tumors. Thus, centrosome amplification and mitotic checkpoint dysfunctions are believed possible causes of chromosomal instability. The Retinoblastoma tumor suppressor (RB participates in the regulation of synchrony between DNA synthesis and centrosome duplication and it is involved in transcription regulation of some mitotic genes. Primary human fibroblasts were transfected transiently with short interfering RNA (siRNA specific for human pRb to investigate the effects of pRb acute loss on chromosomal stability. Results Acutely pRb-depleted fibroblasts showed altered expression of genes necessary for cell cycle progression, centrosome homeostasis, kinetochore and mitotic checkpoint proteins. Despite altered expression of genes involved in the Spindle Assembly Checkpoint (SAC the checkpoint seemed to function properly in pRb-depleted fibroblasts. In particular AURORA-A and PLK1 overexpression suggested that these two genes might have a role in the observed genomic instability. However, when they were post-transcriptionally silenced in pRb-depleted fibroblasts we did not observe reduction in the number of aneuploid cells. This finding suggests that overexpression of these two genes did not contribute to genomic instability triggered by RB acute loss although it affected cell proliferation. Acutely pRb-depleted human fibroblasts showed the presence of micronuclei containing whole chromosomes besides the presence of supernumerary centrosomes and aneuploidy. Conclusion Here we show for the first time that RB acute loss triggers centrosome amplification and aneuploidy in human primary fibroblasts. Altogether, our results suggest that pRb-depleted primary human fibroblasts possess an intact spindle checkpoint and that micronuclei, likely caused by mis-attached kinetochores that in turn trigger

Several studies suggest users of 3,4-methylenedioxymethamphetamine (ecstasy) have low levels of serotonin. Low serotonin may make them susceptible to lowered mood. This work aims to study the acute effects on mood and impulsivity of lowering serotonin levels with acute tryptophan depletion in polydrug ecstasy users and to determine whether effects were different in men and women. In a double-blind cross-over study, participants who had used ecstasy at least 25 times (n = 13) and nonuser controls (n = 17) received a tryptophan-deficient amino acid mixture and a control amino acid mixture containing tryptophan, at least 1 week apart. Mood was measured using the profile of mood states, and impulsivity was measured with the Go/No-Go task. The main result shows that a lowering of mood after acute tryptophan depletion occurred only in female polydrug ecstasy users (n = 7), relative to controls (n = 9). Results from the Go/No-Go task suggested that impulsivity was not increased by acute tryptophan depletion in polydrug ecstasy users. The group sizes were small, when males and females were considered separately. Women polydrug ecstasy users appear to be more susceptible than men to the effects of lowered serotonin levels. If use of ecstasy alone or in conjunction with other drugs causes progressive damage of serotonin neurons, women polydrug ecstasy users may become susceptible to clinical depression.

The lactate level was still above normal in the subacute phase with hyperemia, suggesting lactate production through aerobic glycolysis. Thus, the lactate level in the subacute...... phase probably does not reflect the degree of anaerobic glycolysis in hypoxic neuronal tissue....

To assess the difference of the diagnostic sensitivity of {sup 99m}Tc-Pyrophosphate (PYP) myocardial scintigraphy in acute transmural infarction and acute subendocardial infarction, we analyzed 38 patients with a confirmed transmural infarct, 10 with a subendocardial infarct, 2 with old myocardial infarct, and 10 with other cardiovascular disease (2 unstable angina, 6 stable angina, 1 Prinzmetal angina, and 1 atrial fibrillation) according to Berman's criteria for scintigraphic assessment and then come to conclusion; When only focal myocardial uptake wa used as a criteria for positivity, the diagnostic sensitivity of {sup 99m}Tc-PYP scintigraphy in acute subendocardial myocardial infarction was only 40% (4/10) compared with 86.8% (33/38) of acute transmural myocardial infarction. There was no case that was interpreted as focal myocardial uptake in 2 old myocardial infarction and 10 other cardiovascular disease. The incidence of complication was higher in doughnut pattern of myocardial uptake 50% (3/6) than in non-doughnut focal patterns 19.4% (6/31). It is concluded that focal myocardial uptake is a sensitive indicator suggesting acute myocardial necrosis and that {sup 99m}Tc-PYP myocardial scintigraphy is a sensitive technique for diagnosing acute transmural myocardial infarction, but a insensitive method in acute subendocardial infarction, and that the doughnut pattern of myocardial uptake an provide clues to the patient's future course.

Sixty-six cases of acute appendicitis were proved by surgery during the period from May 1969 to May 1971. The present study was designated to elucidate the findings of roentgen examination in acute appendicitis. The results obtained were summarized as follows: 1. Over 90 percent of cases of acute appendicitis showed significant radiographic findings. 2. Distension and fluid level in cecum and terminal ileum were disclosed approximately 75 percent of cases. It believe diagnostically significant in acute appendicitis. 3. About 10 percent of cases were found extra-alimentary free air. 4. The roentgen findings of the fluid interposed between colonic contents and frank stripesin the right lower quadrant was another interesting findings to suspect acute appendicitis

A case of acute appendicitis in a premature baby in whom diagnosis was suggested on plain films of the abdomen is presented. In this baby air in a hollow viscus suspected of being an enlarged appendix was the clue to diagnosis. The diagnostic dilemma of this rare and life-threatening condition in premature babies and newborns is underlined. The relevance of different imaging modalities and of different findings in this age group is discussed. Awareness of this rare condition and possible differential diagnosis in newborns and premature babies is stressed. (orig.)

Progressive motor deficits are relatively common in acute pontine infarction and frequently associated with increased functional disability. However, the factors that affect the progression of clinical motor weakness are largely unknown. Previous studies have suggested that pontine infarctions are caused mainly by basilar artery stenosis and penetrating artery disease. Recently, lower pons lesions in patients with acute pontine infarctions have been reported to be related to progressive motor deifcits, and ensuing that damage to the corticospinal tracts may be respon-sible for the worsening of neurological symptoms. Here, we review studies on motor weakness progression in pontine infarction and discuss the mechanisms that may underlie the neurologic worsening.

Role of PGC-1α in acute and low-grade inflammation

Olesen, Jesper

The aim of the present thesis was to examine the role of the exercise-induced transcriptional co-activator, PGC-1α, in acute and low-grade inflammation. To investigate this, the following three hypotheses were tested: 1) Skeletal muscle PGC-1α plays an important role in acute LPS-induced systemic...... in skeletal muscle showed a greater fold increase in plasma TNFα than WT mice, when stimulated with LPS. Taken together, these results suggest that skeletal muscle PGC-1α is required for a robust LPS-induced TNFα response. Study II demonstrated that plasma TNFα and IL-6 as well as liver TNFα mRNA and protein...

Pulmonary hydatid cyst in a pregnant patient causing acute respiratory failure

Full Text Available A 21-year-old primigravida, at 32 weeks of gestation, presented with acute onset of respiratory failure and circulatory shock. Chest imaging showed findings suggestive of ruptured hydatid cyst, which was confirmed by histology post-thoracotomy. Tissue cultures from the removed cyst grew Mycobacterium tuberculosis also. She was successfully managed in the intensive care unit and was then discharged home on antituberculosis medications in addition to albendazole after prolonged hospitalization and a need for chest tube for bronchopleural fistula. Acute respiratory failure and anaphylactic shock secondary to ruptured pulmonary hydatid cyst and superimposed pulmonary tuberculosis in a pregnant lady should be considered in patients living in endemic areas.
