    Meola, Mario; Nalesso, Federico; Petrucci, Ilaria; Samoni, Sara; Ronco, Claudio

    2016-01-01

    Kidneys' imaging provides useful information in acute kidney injury (AKI) diagnosis and management. Today, several imaging techniques give information on kidneys anatomy, urinary obstruction, differential diagnosis between AKI and chronic kidney disease (CKD), renal blood flow and glomerular filtration rate. Ultrasound is a safe, non-invasive and repeatable imaging technique so it is widely used in the first level work-up of AKI. The utility of contrast-enhanced computed tomography and magnetic resonance imaging in AKI or in AKI during CKD is limited because of renal toxicity associated with contrast agents used.

    Diarrhoea is an alteration of normal bowel movement characterized by an increase in the water content,volume, or frequency of stools. Diarrhoea needs to be classified according to the trends over time (acute or chronic) and to the characteristics of the stools (watery, fatty, inflammatory). Secretory diarrhoeas,mostly acute and of viral aetiology in more than 70% of cases, are by far the most important subtype of diarrhoeas in terms of frequency, incidence and mortality (over 2.5 million deaths/year in developing countries). Natural and synthetic opiates such as morphine, codeine, and loperamide which react with endogenous opiates (enkephalins, beta-endorphins,dynorphins) mainly act on intestinal motility and slow down transit. An antidiarrhoeal drug developed in recent years, racecadotril, acts as an enkephalinase inhibitor.Clinical studies have shown that it is just as effective as loperamide in resolving acute diarrhoea but with greater reduction in pain and abdominal distension.Some studies have explored the prevalence of diarrhoea in old age. An epidemiological study carried out in Italy by 133 General Practitioners on 5515 elderly outpatients reported a prevalence of diarrhoea, defined according to the Rome criteria, of 9.1%. Infectious diseases (19%) and drug use (16%) were the most commoncauses of diarrhoea in old age. Regardless of the cause,the treatment of elderly patients with diarrhoea must include rehydration and nutritional support. Every year,more than 50 million tourists travel from industrialized countries to places where hygiene levels are poor. At least 75% of those travelling for short periods mention health problems, and in particular traveller's diarrhoea.

  11. Microcirculation in Acute and Chronic Kidney Diseases.

    Zafrani, Lara; Ince, Can

    2015-12-01

    The renal microvasculature is emerging as a key player in acute and chronic kidney diseases. Renal microvascular disease involves alterations in endothelial barrier permeability, exaggerated inflammation, impairment of endothelium-dependent vasorelaxation involving the nitric oxide system, increased oxidative stress, and loss of angiogenic factors. Moreover, evidence suggests that there is a microvascular component to the pathogenesis of renal scarring. New technology is being developed to explore renal microcirculation in vivo in experimental models and humans. This technology will provide a better understanding of the pathogenesis of kidney diseases and will help guide specific therapeutic strategies aimed at restoring the renal microcirculation. This article reviews the cellular and molecular mechanisms of renal microvascular dysfunction in acute and chronic kidney diseases and the potential diagnostic and therapeutic implications of these findings. Recent developments in the monitoring of renal microcirculation are described with respect to their advantages and limitations, and future directions are outlined. PMID:26231789

  13. Strain Echocardiography in Acute Cardiovascular Diseases.

    Favot, Mark; Courage, Cheryl; Ehrman, Robert; Khait, Lyudmila; Levy, Phillip

    2016-01-01

    Echocardiography has become a critical tool in the evaluation of patients presenting to the emergency department (ED) with acute cardiovascular diseases and undifferentiated cardiopulmonary symptoms. New technological advances allow clinicians to accurately measure left ventricular (LV) strain, a superior marker of LV systolic function compared to traditional measures such as ejection fraction, but most emergency physicians (EPs) are unfamiliar with this method of echocardiographic assessment. This article discusses the application of LV longitudinal strain in the ED and reviews how it has been used in various disease states including acute heart failure, acute coronary syndromes (ACS) and pulmonary embolism. It is important for EPs to understand the utility of technological and software advances in ultrasound and how new methods can build on traditional two-dimensional and Doppler techniques of standard echocardiography. The next step in competency development for EP-performed focused echocardiography is to adopt novel approaches such as strain using speckle-tracking software in the management of patients with acute cardiovascular disease. With the advent of speckle tracking, strain image acquisition and interpretation has become semi-automated making it something that could be routinely added to the sonographic evaluation of patients presenting to the ED with cardiovascular disease. Once strain imaging is adopted by skilled EPs, focused echocardiography can be expanded and more direct, phenotype-driven care may be achievable for ED patients with a variety of conditions including heart failure, ACS and shock.

  16. Acute recurrent pancreatitis: An autoimmune disease?

    Raffaele Pezzilli

    2008-01-01

    In this review article,we will briefly describe the main characteristics of autoimmune pancreatitis and then we will concentrate on our aim,namely,evaluating the clinical characteristics of patients having recurrence of pain from the disease.In fact,the open question is to evaluate the possible presence of autoimmune pancreatitis in patients with an undefined etiology of acute pancreatitis and for this reason we carried out a search in the literature in order to explore this issue.In cases of recurrent attacks of pain in patients with "idiopathic"pancreatitis,we need to keep in mind the possibility that our patients may have autoimmune pancreatitis.Even though the frequency of this disease seems to be quite low,we believe that in the future,by increasing our knowledge on the subject,we will be able to diagnose an ever-increasing number of patients having acute recurrence of pain from autoimmune pancreatitis.

The strong correlation between MRD levels and risk of relapse in childhood ALL is well established; studies in...

  18. Crohn's Disease and Acute Pancreatitis: A Review of Literature

    Sarfaraz Jasdanwala

    2015-03-01

    Full Text Available Crohn's disease, a transmural inflammatory bowel disease, has many well-known extra-intestinal manifestations and complications. Although acute pancreatitis has a higher incidence in patients with Crohn's disease as compared to the general population, acute pancreatitis is still relatively uncommon in patients with Crohn's disease. Patients with Crohn's disease are at an approximately fourfold higher risk than the general population to develop acute pancreatitis. The risk of developing acute pancreatitis is higher in females as compared to males. Acute pancreatitis can occur at any age with higher incidence reported in patients in their 20s and between 40- 50 years of age. The severity and prognosis of acute pancreatitis in patients with Crohn's disease is the same as in general population. Acute pancreatitis can occur before onset of intestinal Crohn's disease, this presentation being more common in children than adults. It can also occur as the presenting symptom. However, most commonly it occurs after intestinal symptoms have manifest with a mean time interval between the initial presentation and development of acute pancreatitis being 2 years. There are several etiological factors contributing to acute pancreatitis in patients with crohn's disease. It is not clear whether acute pancreatitis is a direct extra-intestinal manifestation of Crohn's disease; however majority of the cases of acute pancreatitis in patients with Crohn's disease are due to GS and medications. Drugs used for the treatment of Crohn's disease that have been reported to cause acute pancreatitis include 5-ASA agents, azathioprine and 6 mercaptopurine, metornidazole and corticosteroids. Recent evidence has emerged correlating both type 1 and 2 autoimmune pancreatitis with Crohn's disease. Understanding the association between the two disease entities is key to effectively manage patients with Crohn's disease and acute pancreatitis.

  19. Transvaginal sonography of acute pelvic inflammatory disease

    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.

  20. Acute renal dysfunction in liver diseases

    2007-01-01

    Renal dysfunction is common in liver diseases, either as part of multiorgan involvement in acute illness or secondary to advanced liver disease. The presence of renal impairment in both groups is a poor prognostic indicator. Renal failure is often multifactorial and can present as pre-renal or intrinsic renal dysfunction. Obstructive or post renal dysfunction only rarely complicates liver disease. Hepatorenal syndrome (MRS) is a unique form of renal failure associated with advanced liver disease or cirrhosis, and is characterized by functional renal impairment without significant changes in renal histology. Irrespective of the type of renal failure, renal hypoperfusion is the central pathogenetic mechanism, due either to reduced perfusion pressure or increased renal vascular resistance. Volume expansion, avoidance of precipitating factors and treatment of underlying liver disease constitute the mainstay of therapy to prevent and reverse renal impairment. Splanchnic vasoconstrictor agents, such as terlipressin, along with volume expansion, and early placement of transjugular intrahepatic portosystemic shunt (TIPS) may be effective in improving renal function in HRS. Continuous renal replacement therapy (CRRT) and molecular absorbent recirculating system (MARS) in selected patients may be life saving while awaiting liver transplantation.

    Acute rheumatic fever (ARF) is the result of an autoimmune response to pharyngitis caused by infection with group A Streptococcus. The long-term damage to cardiac valves caused by ARF, which can result from a single severe episode or from multiple recurrent episodes of the illness, is known as rheumatic heart disease (RHD) and is a notable cause of morbidity and mortality in resource-poor settings around the world. Although our understanding of disease pathogenesis has advanced in recent years, this has not led to dramatic improvements in diagnostic approaches, which are still reliant on clinical features using the Jones Criteria, or treatment practices. Indeed, penicillin has been the mainstay of treatment for decades and there is no other treatment that has been proven to alter the likelihood or the severity of RHD after an episode of ARF. Recent advances - including the use of echocardiographic diagnosis in those with ARF and in screening for early detection of RHD, progress in developing group A streptococcal vaccines and an increased focus on the lived experience of those with RHD and the need to improve quality of life - give cause for optimism that progress will be made in coming years against this neglected disease that affects populations around the world, but is a particular issue for those living in poverty.

  7. Minimal residual disease in acute lymphoblastic leukemia.

    Campana, Dario

    2009-01-01

    In patients with acute lymphoblastic leukemia (ALL), monitoring of minimal residual disease (MRD) offers a way to precisely assess early treatment response and detect relapse. Established methods to study MRD are flow cytometric detection of abnormal immunophenotypes, polymerase chain reaction (PCR) amplification of antigen-receptor genes, and PCR amplification of fusion transcripts. The strong correlation between MRD levels and risk of relapse in childhood ALL is well demonstrated; studies in adult patients also support its prognostic value. Hence, results of MRD studies can be used to select treatment intensity and duration, and to estimate the optimal timing for hematopoietic stem cell transplantation. Practical issues in the implementation of MRD assays in clinical studies include determining the most informative time point to study MRD and the levels of MRD that will trigger changes in treatment intensity, as well as the relative cost and informative power of different methodologies. The identification of new markers of leukemia and the use of increasingly refined assays should further facilitate routine monitoring of MRD and help to clarify the cellular and biologic features of leukemic cells that resist chemotherapy in vivo.

    2016-01-01

    Hypertriglyceridemia is a rare, but since a long time well known etiology for acute pancreatitis. It could occure alone or coactive with other triggers like alcohlic excess. Nevertheless it found no approach to the current classifications and parameters of prognosis of the acute pancreatitis. We refer about two patients with hypertriglyceridemia and acute pancreatitis, whose initial disease was limited on the tail of the pancreas with just a circumscripted or--in the other case--no necrosis. However, in both cases and although a consequent treatment started immediately, a serious process developed including a life-threatening acute respiratory distress syndrome in one case, which necessitated an extracorporal membrane oxygenation.

    Acute Lyme disease results from transmission of and infection by the bacterium Borrelia burgdorferi following a tick bite. During acute infection, bacteria can disseminate to the central nervous system (CNS) leading to the development of Lyme meningitis. Here we have analyzed pooled cerebrospinal fluid (CSF) allowing for a deep view into the proteome for a cohort of patients with early-disseminated Lyme disease and CSF inflammation leading to the identification of proteins that reflect host responses, which are distinct for subjects with acute Lyme disease. Additionally, we analyzed individual patient samples and quantified changes in protein abundance employing label-free quantitative mass spectrometry based methods. The measured changes in protein abundances reflect the impact of acute Lyme disease on the CNS as presented in CSF. We have identified 89 proteins that differ significantly in abundance in patients with acute Lyme disease. A number of the differentially abundant proteins have been found to be localized to brain synapse and thus constitute important leads for better understanding of the neurological consequence of disseminated Lyme disease.

    International Renal Interest Society chronic kidney disease Stage 1 and acute kidney injury Grade I categorizations of kidney disease are often confused or ignored because patients are nonazotemic and generally asymptomatic. Recent evidence suggests these seemingly disparate conditions may be mechanistically linked and interrelated. Active kidney injury biomarkers have the potential to establish a new understanding for traditional views of chronic kidney disease, including its early identification and possible mediators of its progression, which, if validated, would establish a new and sophisticated paradigm for the understanding and approach to the diagnostic evaluation, and treatment of urinary disease in dogs and cats.

    Full Text Available "Background: Malnutrition and infectious diseases both occur in the same unfortunate children and together they play a major role in causing the high morbidity and mortality in them. Out of all the childhood illnesses, acute respiratory tract infections, diarrhoeal diseases and malnutrition are the principle causes of illness and death in the developing countries. Acute Diarrhoeal diseases (ADD’s are reported to be the 2nd leading cause of child morbidity and mortality. Objectives: To study the attack rate of Acute Diarrhoeal Disease among pre-school children and to study the socio-demographic variables of pre-school children suffering from Acute Diarrhoeal Disease. Methods: A Longitudinal study was conducted among preschool children (3-5years who were selected from Private pre-primary school of urban area and followed for the period of one year. Mother/guardian/teacher was interviewed by using pre-tested proforma during this period. Results: About 56% of children found suffering from ADD with 0.6 episodes per children per year among private pre-primary school. Higher proportions of ADD affected children were residing in nuclear type of family, belonging to middle socio-economic class, mothers were literate & housewives, born with order >2 compared to non ADD affected children. Conclusion: Maximum number of children from private pre-primary schools suffered with nearly one attack of Acute Diarrhoeal Disease with maternal illiteracy and working mothers found favorable factors. Immunization coverage, EBF and proper weaning play a very important role in prevention of infections."

    Since it allows a better quality of life, return to work must be considered ever since the early stages of the health care pathway following a cardiovascular disease. Seeing the occupational physician beforehand, so as to anticipate the return to work, is crucial. Dialogue between cardiologists, general practitioners and occupational physician, still observing medical confidentiality, must allow a better quality of return to work. Being recognized as a handicapped worker is a key element in the prevention of socio-professional exclusion. Even when dealing with long sick leave, permanent functional injuries or job loss, guiding the patients towards the appropriate person can improve return to work and job retention in the long term.

  5. Pulmonary thromboembolic disease. Clinical management of acute and chronic disease.

    Torbicki, Adam

    2010-07-01

    Pulmonary thromboembolism falls between the areas of pulmonology and cardiology, internal medicine and intensive care, radiology and nuclear medicine, and hematology and cardiothoracic surgery. Depending on their clinical background, physicians faced with a patient with a pulmonary thromboembolism may speak different languages and adopt different treatment approaches. Now, however, there is an opportunity to end the Tower of Babel surrounding pulmonary thromboembolism. There is a growing acknowledgement that the key clinical problems in both acute pulmonary embolism and chronic thromboembolic pulmonary hypertension are linked to right ventricular pressure overload and right ventricular failure. As a result, cardiologists and cardiac intensive care specialists are taking an increasing interest in understanding and combating these conditions. The European Society of Cardiology was the first to elaborate comprehensive clinical practice guidelines for pulmonary thromboembolism and chronic thromboembolic pulmonary hypertension. The task forces involved in producing these guidelines included radiologists, pulmonologists, hematologists, intensive care physicians and surgeons, which ensured that the final document was universally acceptable. The aim of this article was to provide an overview of the epidemiology, risk factors, diagnosis, treatment, prognosis and prevention of acute pulmonary thromboembolism and chronic thromboembolic pulmonary hypertension, while taking into account European Society of Cardiology guidelines and incorporating new evidence where necessary.

  6. Acute renal failure: outcomes and risk of chronic kidney disease.

    Block, C A; Schoolwerth, A C

    2007-09-01

    Acute renal failure (ARF) is a common condition, especially among the critically ill, and confers a high mortality. The incidence of ARF is increasing. Efforts such as the Acute Dialysis Quality Initiative (ADQI) are being undertaken to establish a consensus definition of ARF, and to distinguish between varying degrees of acute kidney injury that might confer a different prognosis. Data are emerging to allow comparison of the epidemiology of ARF across institutions internationally. There is ongoing recognition of the important interaction between ARF and chronic kidney disease and more information regarding recovery from ARF is available. Controversy exists regarding the optimal management of ARF. Recent publications emphasize the importance of timing and dose of renal replacement therapy rather than the modality of treatment (intermittent hemodialysis vs continuous therapies). These issues are explored in this review. PMID:17912228

  7. Managing acute and chronic renal stone disease.

    Moran, Conor P; Courtney, Aisling E

    2016-02-01

    Nephrolithiasis, or renal stone disease, is common and the incidence is increasing globally. In the UK the lifetime risk is estimated to be 8-10%. On a population level, the increase in stone incidence, erosion of gender disparity, and younger age of onset is likely to reflect increasing prevalence of obesity and a Western diet with a high intake of animal protein and salt. Stones can be detected by a variety of imaging techniques. The gold standard is a non-contrast CT of kidneys, ureters and bladder (CT KUB) which can identify > 99% of stones. CT KUB should be the primary mode of imaging for all patients with colic unless contraindicated. In such instances, or if a CT KUB is not available, an ultrasound KUB is an alternative. This has advantages in terms of radiation exposure and cost, but is limited in sensitivity, particularly for ureteric stones. Once diagnosed, a plain film KUB can be used for follow-up of radiopaque stones. For most patients diclofenac is a reasonable first choice of analgesia, e.g. 50-100 mg rectally, or 75 mg IM. Opioid medication can worsen nausea and be less effective, but should be used if there is a contraindication to NSAIDs. A combination of diclofenac, paracetamol, and/or codeine regularly can provide adequate pain control in many cases. Failure of this analgesic combination should prompt consideration of secondary care support. If a ureteric stone 10 mm in diameter should be discussed with the urology service as they are unlikely to pass spontaneously. PMID:27032222

  11. Investigation of the acute inflammatory response in Crohn's disease.

    MARKS, D. J. B.

    2006-01-01

    Most theories concerning the primary cause of Crohn's disease focus on over-activation of the immune response. Paradoxically, the defect may instead relate to diminished acute inflammation. Neutrophil accumulation to sites of dermal trauma has been shown to be reduced. Were the same phenomenon to occur in the gut, it might impair bacterial clearance thus provoking granuloma formation. In this thesis, a novel technique demonstrated attenuated neutrophil accumulation following trauma to the bow...

  12. Metabolomics and Its Application to Acute Lung Diseases.

    Stringer, Kathleen A; McKay, Ryan T; Karnovsky, Alla; Quémerais, Bernadette; Lacy, Paige

    2016-01-01

    Metabolomics is a rapidly expanding field of systems biology that is gaining significant attention in many areas of biomedical research. Also known as metabonomics, it comprises the analysis of all small molecules or metabolites that are present within an organism or a specific compartment of the body. Metabolite detection and quantification provide a valuable addition to genomics and proteomics and give unique insights into metabolic changes that occur in tangent to alterations in gene and protein activity that are associated with disease. As a novel approach to understanding disease, metabolomics provides a "snapshot" in time of all metabolites present in a biological sample such as whole blood, plasma, serum, urine, and many other specimens that may be obtained from either patients or experimental models. In this article, we review the burgeoning field of metabolomics in its application to acute lung diseases, specifically pneumonia and acute respiratory disease syndrome (ARDS). We also discuss the potential applications of metabolomics for monitoring exposure to aerosolized environmental toxins. Recent reports have suggested that metabolomics analysis using nuclear magnetic resonance (NMR) and mass spectrometry (MS) approaches may provide clinicians with the opportunity to identify new biomarkers that may predict progression to more severe disease, such as sepsis, which kills many patients each year. In addition, metabolomics may provide more detailed phenotyping of patient heterogeneity, which is needed to achieve the goal of precision medicine. However, although several experimental and clinical metabolomics studies have been conducted assessing the application of the science to acute lung diseases, only incremental progress has been made. Specifically, little is known about the metabolic phenotypes of these illnesses. These data are needed to substantiate metabolomics biomarker credentials so that clinicians can employ them for clinical decision-making and

  13. Noninvasive imaging in acute coronary disease. A clinical perspective

    Numerous highly complex and sensitive noninvasive imaging techniques have enhanced the care of patients with acute myocardial infarction. Optimum use requires specific objectives to be defined in advance, including a review of the potential impact of the test on subsequent decisions. An additional issue that is subject to scrutiny in the current climate of cost containment relates to the incremental value of a specific examination. The imaging modality to be used will partially depend on other issues, including accessibility, cost, and interindividual or institutional expertise with a particular technique. Major applications in noninvasive imaging in the acute coronary syndromes include the following: (1) diagnosis, including identification of associated diseases and contraindications for acute reperfusion; (2) evaluation and management of complications; (3) determination of prognosis (both early and late); (4) estimation of myocardial viability; (5) assessment of therapeutic efficacy; (6) investigational approaches, including 99mTc-sestamibi tomographic imaging, ultrafast cine computed tomographic scanning, and nuclear magnetic resonance imaging. Previous studies in the prethrombolytic era have documented the powerful impact of radionuclide stress testing on prognosis, but this needs to be reevaluated in the light of the changing current population undergoing stress testing. Preliminary data imply that the prognostic accuracy of stress testing after thrombolytic therapy is diminished. Moreover, the role of the open infarct-related artery in traditional estimates of prognosis requires further study. Noninvasive imaging has multiple applications in the diagnosis and management of patients with acute coronary disease, but the decision to use a specific technology in a particular circumstance mandates good clinical judgment and selectivity. 82 references

  14. Compared with parenteral nutrition, enteral feeding attenuates the acute phase response and improves disease severity in acute pancreatitis

    2015-01-01

    Full Text Available Context: Lithium carbonate is a psychiatric medication commonly used in the treatment of bipolar disorder. It has been implicated in inducing nephrogenic diabetes inspidus, chronic tubulointerstitial nephropathy, and acute tubular necrosis. We describe a case of lithium-induced minimal change disease (MCD and acute kidney injury (AKI. Case Report: A 32-year-old female with a medical history of bipolar disorder treated with chronic lithium therapy presented with anasarca, fatigue, and tremors. Work-up revealed supra-therapeutic lithium levels, hypoalbuminemia, and significant proteinuria. The patient was treated conservatively with fluids and discontinuation of lithium therapy. Subsequently, she developed significant AKI and persistent proteinuria. She underwent a renal biopsy that demonstrated effacement of podocyte foot processes consistent with lithium-induced MCD. This was treated with corticosteroids, which decreased the proteinuria and resolved all the patient′s symptoms. Conclusion: Lithium-induced MCD is a rare disease that affects patients of all ages. It is often associated with therapeutic lithium and is typically resolved with discontinuation of lithium. In some cases, concurrent AKI may result due to vascular obstruction from hyperalbuminuria and associated renal interstitial edema. Corticosteroids may be needed to reduce the proteinuria and prevent progression to chronic kidney disease. As such, patients on lithium therapy may benefit from monitoring of glomerular function via urinalysis to prevent the onset of nephrotic syndrome.

  16. Relationship Between Periodontal Disease and Acute Myocardial Infarction

    2008-07-01

    Full Text Available Background: Conventional risk factors for coronary artery disease and myocardial infarction do not explain all of the clinical and epidemiological features of the disease. Periodontal disease is a common bacterial and destructive disorder of oral tissues. Many studies demonstrate close association between chronic periodontitis and development of generalized inflammation, vascular endothelial injury, and atherosclesis. Periodontal disease has been convincingly emerging as an important independent risk factor for ischemic heart disease. A case - control study was carried out to assess the prevalence of periodontitis in patients with Acute myocardial Infarction (AMI and evaluate the possible relationship between AMI and chronic periodontitis. Patients and Methods: A number of 160 patients, aged 35 to 70 years old, enrolled in the study. Eighty patients (43 men, 37 women were examined four days after hospitalization due to AMI. Control group consisted of 80 persons (38 men, 42 women with normal coronary angiography. The following periodontal parameters were examined: Plaque index (PI, gingiral index (GI, bleeding on probing (BOP, probing depth (PD, clinical attachment loss (CAL and number of sites with CAL.Results: The case, compared to control showed significantly worse results for some periodontal variables studied: The mean of PD and PD > 3 mm, CAL, and number of sites with CAL, had worse results compared to control despite similar oral hygiene and frequency of brushing. The confounding factors for the present study were found to be hypertension and diabetes. Conclusion: The association between periodontitis and acute myocardial infarction was significant after adjusting for conventional risk factors for AMI.

    2002-01-01

    Full Text Available Graft-versus-host-disease (GVHD is the major complication of allogeneic Bone Marrow Transplant (BMT. Older BMT recipients are a greater risk for acute GVHD after allogeneic BMT, but the causes of this association are poorly understood. Using well-characterized murine BMT models we have explored the mechanisms of increased GVHD in older mice. GVHD mortality and morbidity, and pathologic and biochemical indices were all worse in old recipients. Donor T cell responses were significantly increased in old recipients both in vivo and in vitro when stimulated by antigen-presenting cells (APCs from old mice. In a haploidential GVHD model, CD4+ donor T cells mediated more severe GVHD in old mice. We confirmed the role of aged APCs in GVHD using bone marrow chimera recipient created with either old or young bone marrow. APCs from these mice also stimulated greater responses from allogeneic cells in vitro. In a separate set of experiments we evaluated whether alloantigen expression on host target epithelium is essential for tissue damage induced by GVHD. Using bone marrow chimeras recipients in which either MHC II or MHC I alloantigen was expressed only on APCs, we found that acute GVHD does not require alloantigen expression on host target epithelium and that neutralization of tumor necrosis factor-alpha and interleukin-1 prevents acute GVHD. These results pertain to CD4-mediated GVHD and to a lesser extent in CD8-mediated GVHD, and confirm the central role of most APCs as well as inflammatory cytokines.

  1. Acute exacerbations of chronic obstructive pulmonary disease: causes and impacts.

    Chhabra, Sunil K; Dash, Devi Jyoti

    2014-01-01

    Acute exacerbations of chronic obstructive pulmonary disease (AECOPD) are recognised clinically as episodes of increased breathlessness and productive cough requiring a more intensive treatment. A subset of patients with this disease is especially prone to such exacerbations. These patients are labelled as 'frequent exacerbators'. Though yet poorly characterised in terms of host characteristics, including any genetic basis, these patients are believed to represent a distinct phenotype as they have a different natural history with a more progressive disease and a poorer prognosis than those who get exacerbations infrequently. Most exacerbations appear to be associated with infective triggers, either bacterial or viral, although 'non-infective' agents, such as air pollution and other irritants may also be important. Susceptibility to exacerbations is determined by multiple factors. Several risk factors have been identified, some of which are modifiable. Chronic obstructive pulmonary disease (COPD) exacerbations are major drivers of health status and patient-centered outcomes, and are a major reason for health care utilisation including hospitalisations and intensive care admissions. These are associated with considerable morbidity and mortality, both immediate and long-term. These episodes have a negative impact on the patient and the disease including high economic burden, increased mortality, worsening of health status, limitation of activity, and aggravation of comorbidities including cardiovascular disease, osteoporosis and neuro-psychiatric complications. Exacerbations also increase the rate of progression of disease, increasing the annual decline in lung function and leading to a poorer prognosis. Evaluation of risk of exacerbations is now included as a major component of the initial assessment of a patient with COPD in addition to the traditionally used lung function parameter, forced expiratory volume in one second (FEV1).

    2014-08-21

    Acute hepatopancreatic necrosis disease (AHPND), which has also been referred to as early mortality syndrome (EMS), initially emerged as a destructive disease of cultured shrimp species in Asia in 2009. The pathogen associated with the disease, Vibrio parahaemolyticus, subsequently spread to the Western Hemisphere and emerged in Mexico in early 2013. The spread to the Western Hemisphere is a major concern to shrimp producers in the region. To date, the only peer-reviewed published method for determining whether mortalities are due to AHPND is through histological examination. A novel PCR detection method was employed to assess samples from Mexico in order to confirm the presence of the pathogen in this country. This manuscript details the detection methods used to confirm the presence of AHPND in Mexico. Both immersion and per os challenge studies were used to expose the Penaeus vannamei to the bacteria in order to induce the disease. Histological analysis confirmed AHPND status following the challenge studies. Also provided are the details of the molecular test by PCR that was used for screening candidate V. parahaemolyticus isolates. A rapid PCR assay for detection of AHPND may help with early detection and help prevent the spread of AHPND to other countries. PMID:25144120

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

    Brown, Marvelle

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

    Full Text Available Simon E Brill, Jadwiga A Wedzicha Airway Disease Section, National Heart and Lung Institute, Imperial College, London, UK Abstract: Acute exacerbations of chronic obstructive pulmonary disease (COPD are important events in the history of this debilitating lung condition. Associated health care utilization and morbidity are high, and many patients require supplemental oxygen or ventilatory support. The last 2 decades have seen a substantial increase in our understanding of the best way to manage the respiratory failure suffered by many patients during this high-risk period. This review article examines the evidence underlying supplemental oxygen therapy during exacerbations of COPD. We first discuss the epidemiology and pathophysiology of respiratory failure in COPD during exacerbations. The rationale and evidence underlying oxygen therapy, including the risks when administered inappropriately, are then discussed, along with further strategies for ventilatory support. We also review current recommendations for best practice, including methods for improving oxygen provision in the future.

  5. Mitochondrial dysfunction in inherited renal disease and acute kidney injury.

    Emma, Francesco; Montini, Giovanni; Parikh, Samir M; Salviati, Leonardo

    2016-05-01

    Mitochondria are increasingly recognized as key players in genetic and acquired renal diseases. Most mitochondrial cytopathies that cause renal symptoms are characterized by tubular defects, but glomerular, tubulointerstitial and cystic diseases have also been described. For example, defects in coenzyme Q10 (CoQ10) biosynthesis and the mitochondrial DNA 3243 A>G mutation are important causes of focal segmental glomerulosclerosis in children and in adults, respectively. Although they sometimes present with isolated renal findings, mitochondrial diseases are frequently associated with symptoms related to central nervous system and neuromuscular involvement. They can result from mutations in nuclear genes that are inherited according to classic Mendelian rules or from mutations in mitochondrial DNA, which are transmitted according to more complex rules of mitochondrial genetics. Diagnosis of mitochondrial disorders involves clinical characterization of patients in combination with biochemical and genetic analyses. In particular, prompt diagnosis of CoQ10 biosynthesis defects is imperative because of their potentially reversible nature. In acute kidney injury (AKI), mitochondrial dysfunction contributes to the physiopathology of tissue injury, whereas mitochondrial biogenesis has an important role in the recovery of renal function. Potential therapies that target mitochondrial dysfunction or promote mitochondrial regeneration are being developed to limit renal damage during AKI and promote repair of injured tissue.

  6. CT appearance of acute inflammatory disease of the renal interstitium

    Today, infection remains the most common disease of the urinary tract and constitutes almost 75% of patient problems requiring urologic evaluation. There have been several major factors responsible for our better understanding of the nature and pathophysiology of urinary tract infection. One has been quantitated urine bacteriology and another, the discovery that a significant part of the apparently healthy adult female population has asymptomatic bacteriuria. Abnormal conditions such as neurogenic bladder, bladder malignancy, prolonged catheter drainage and reflux, altered host resistance, diabetes mellitus, and urinary tract obstruction, as well as pregnancy, may either predispose to or be implicated in the pathogenesis of urinary tract infection. There is a wide range of conditions that result in acute renal inflammation and those under discussion affect primarily the interstitium. This term refers to the connective tissue elements separating the tubules in the cortex and medulla. Hence, the interstitial nephritides are to be distinguished from the glomerulonephritides and fall into two general etiologic categories: infectious and noninfectious

  7. Acute Psychosis as Major Clinical Presentation of Legionnaires’ Disease

    Ricardo Coentre

    2016-01-01

    Full Text Available We report a case of a 61-year-old woman who presented with acute psychosis as a major manifestation of Legionnaires’ disease in the absence of other neuropsychiatric symptoms. Clinical history revealed dry cough and nausea. Observation showed fever and auscultation crackles in the lower lobe of the right lung. Laboratory testing demonstrated elevated C-reactive protein and lung chest radiograph showed patchy peribronchial and right lower lobe consolidation. Soon after admission, she started producing purulent sputum. Epidemiological data suggested Legionella pneumophila as possible cause of the clinical picture that was confirmed by urinary antigen detection and polymerase chain reaction of the sputum. She was treated with levofloxacin 750 mg/day for 10 days with complete remission of pulmonary and psychiatric symptoms. She has not had further psychotic symptoms.

    Invasive fungal disease (IFD) represents an important complication in patients with acute lymphoid leukemia (ALL). The objectives of this study were to determine the prevalence of IFD in ALL patients with neutropenia, identify factors associated with IFD, and estimate the impact of IFD on the outcome. All patients with ALL who developed febrile neutropenia from 1987 to 2013 were evaluated. Cases of IFD were classified as proven or probable. Factors associated with IFD were evaluated by comparing episodes with and without a diagnosis of IFD. Among 350 episodes of febrile neutropenia, 31 IFDs were diagnosed (8.8%). Prolonged neutropenia was the only factor associated with IFD caused by yeasts. Factors associated with IFD caused by molds by multivariate analysis were the period after 2008, receipt of allogeneic transplant, relapsed ALL and prolonged neutropenia. Patients in relapse should receive induction chemotherapy in rooms with HEPA filter and receive antifungal prophylaxis. PMID:26949001

    Polycystic kidney disease is an inherited condition, characterized by the development of cysts in the kidney, as well as in other organs. Patients with polycystic kidney can suffer from the same causes of acute kidney injury as the general population. Nephritic syndrome is an uncommon cause of acute kidney injury in the general population and less common in patients with polycystic kidney disease. We report the second case of crescentic glomerulonephritis, causing acute kidney injury, in a pa...

    2007-01-01

    AIM: To describe the diagnostic criteria for acute liver failure due to Wilson disease (WD), which is an uncommon cause of acute liver failure (ALF).METHODS: We compared findings of patients presenting with ALF due to WD to those with ALF of other etiologies.RESULTS: Previously described criteria, such as low alkaline phosphatase activity, ratio of low alkaline phosphatase to total bilirubin or ratio of high aspartate aminotransferase (AST) to alanine aminotransferase (ALT), failed to identify patients with ALF due to WD. There were significant differences in low ALT and AST activities (53 ± 43 vs 1982 ± 938, P < 0.0001 and 87 ± 44 vs 2756 ± 2941, P = 0.037, respectively), low choline esterase activity (1.79 ± 1.2 vs 4.30 ± 1.2, P = 0.009), high urine copper concentrations (93.4 ± 144.0 vs 3.5 ± 1.8, P = 0.001) and low hemoglobin (7.0 ± 2.2 vs 12.6 ± 1.8, P < 0.0001) in patients with ALF caused by WD as compared with other etiologies. Interestingly, 4 of 7 patients with ALF due to WD survived without liver transplantation.CONCLUSION: In ALF, these criteria can help establish a diagnosis of WD. Where applicable, slit-lamp examination for presence of Kayser-Fleischer rings and liver biopsy for determination of hepatic copper concentration still remain important for the diagnosis of ALF due to WD. The need for liver transplantation should be evaluated carefully as the prognosis is not necessarily fatal.

  14. Review of Elephant Endotheliotropic Herpesviruses and Acute Hemorrhagic Disease.

    Long, Simon Y; Latimer, Erin M; Hayward, Gary S

    2016-02-24

    More than 100 young captive and wild Asian elephants are known to have died from a rapid-onset, acute hemorrhagic disease caused primarily by multiple distinct strains of two closely related chimeric variants of a novel herpesvirus species designated elephant endotheliotropic herpesvirus (EEHV1A and EEHV1B). These and two other species of Probosciviruses (EEHV4 and EEHV5) are evidently ancient and likely nearly ubiquitous asymptomatic infections of adult Asian elephants worldwide that are occasionally shed in trunk wash secretions. Although only a handful of similar cases have been observed in African elephants, they also have proved to harbor their own multiple and distinct species of Probosciviruses-EEHV2, EEHV3, EEHV6, and EEHV7-found in lung and skin nodules or saliva. For reasons that are not yet understood, approximately 20% of Asian elephant calves appear to be susceptible to the disease when primary infections are not controlled by normal innate cellular and humoral immune responses. Sensitive specific polymerase chain reaction (PCR) DNA blood tests have been developed, routine monitoring has been established, the complete large DNA genomes of each of the four Asian EEHV species have now been sequenced, and PCR gene subtyping has provided unambiguous evidence that this is a sporadic rather than epidemic disease that it is not being spread among zoos or other elephant housing facilities. Nevertheless, researchers have not yet been able to propagate EEHV in cell culture, determine whether or not human antiherpesvirus drugs are effective inhibitors, or develop serology assays that can distinguish between antibodies against the multiple different EEHV species.

    Acute hepatopancreatic necrosis disease (AHPND), also called early mortality syndrome (EMS), is a recently emergent shrimp bacterial disease that has resulted in substantial economic losses since 2009. AHPND is known to be caused by strains of Vibrio parahaemolyticus that contain a unique virulence plasmid, but the pathology of the disease is still unclear. In this study, we show that AHPND-causing strains of V. parahaemolyticus secrete the plasmid-encoded binary toxin PirAB(vp) into the culture medium. We further determined that, after shrimp were challenged with AHPND-causing bacteria, the bacteria initially colonized the stomach, where they started to produce PirAB(vp) toxin. At the same early time point (6 hpi), PirB(vp) toxin, but not PirA(vp) toxin, was detected in the hepatopancreas, and the characteristic histopathological signs of AHPND, including sloughing of the epithelial cells of the hepatopancreatic tubules, were also seen. Although some previous studies have found that both components of the binary PirAB(vp) toxin are necessary to induce a toxic effect, our present results are consistent with other studies which have suggested that PirB(vp) alone may be sufficient to cause cellular damage. At later time points, the bacteria and PirA(vp) and PirB(vp) toxins were all detected in the hepatopancreas. We also show that Raman spectroscopy "Whole organism fingerprints" were unable to distinguish between AHPND-causing and non-AHPND causing strains. Lastly, by using minimum inhibitory concentrations, we found that both virulent and non-virulent V. parahaemolyticus strains were resistant to several antibiotics, suggesting that the use of antibiotics in shrimp culture should be more strictly regulated.

    significant limitation for clinical applications of stem cell transplantation. Severe immunesuppression or depletion of mature donor T cells from the transplant leads to increased probability of relapse and weakens anti-infectious immunity. Hence, further search for alternative, more specific ways to prevent GVHD is required. This review will focus on the mechanisms of alloreactive T lymphocyte clone development and key pathogenetic stages of acute “graft versus host” disease.

  17. Acute kidney injury: Renal disease in the ICU.

    Seller-Pérez, G; Más-Font, S; Pérez-Calvo, C; Villa-Díaz, P; Celaya-López, M; Herrera-Gutiérrez, M E

    2016-01-01

    Acute kidney injury (AKI) in the ICU frequently requires costly supportive therapies, has high morbidity, and its long-term prognosis is not as good as it has been presumed so far. Consequently, AKI generates a significant burden for the healthcare system. The problem is that AKI lacks an effective treatment and the best approach relies on early secondary prevention. Therefore, to facilitate early diagnosis, a broader definition of AKI should be established, and a marker with more sensitivity and early-detection capacity than serum creatinine - the most common marker of AKI - should be identified. Fortunately, new classification systems (RIFLE, AKIN or KDIGO) have been developed to solve these problems, and the discovery of new biomarkers for kidney injury will hopefully change the way we approach renal patients. As a first step, the concept of renal failure has changed from being a "static" disease to being a "dynamic process" that requires continuous evaluation of kidney function adapted to the reality of the ICU patient.

  20. Blood transfusion for the treatment of acute anaemia in inflammatory bowel disease and other digestive diseases

    José Antonio García-Erce, Fernando Gomollón, Manuel Muñoz

    2009-10-01

    Full Text Available Allogeneic blood transfusion (ABT is frequently used as the first therapeutic option for the treatment of acute anaemia in patients with inflammatory bowel disease (IBD, especially when it developed due to gastrointestinal or perioperative blood loss, but is not risk-free. Adverse effects of ABT include, but are not limited to, acute hemolytic reaction (wrong blood or wrong patient, febrile non-hemolytic transfusional reaction, bacterial contamination, transfusion-related acute lung injury, transfusion associated circulatory overload, transfusion-related immuno-modulation, and transmission of almost all infectious diseases (bacteria, virus, protozoa and prion, which might result in increased risk of morbidity and mortality. Unfortunately, the main physiological goal of ABT, i.e. to increase oxygen consumption by the hypoxic tissues, has not been well documented. In contrast, the ABT is usually misused only to increase the haemoglobin level within a fixed protocol [mostly two by two packed red blood cell (PRC units] independently of the patient’s tolerance to normovolemic anaemia or his clinical response to the transfusion of PRC units according to a “one-by-one” administration schedule. Evidence-based clinical guidelines may promote best transfusion practices by implementing restrictive transfusion protocols, thus reducing variability and minimizing the avoidable risks of transfusion, and the use of autologous blood and pharmacologic alternatives. In this regard, preoperative autologous blood donation (PABD consistently diminished the frequency of ABT, although its contribution to ABT avoidance is reduced when performed under a transfusion protocol. In addition, interpretation of utility of PABD in surgical IBD patients is hampered by scarcity of published data. However, the role of autologous red blood cells as drug carriers is promising. Finally, it must be stressed that a combination of methods used within well-constructed protocols

    Acute disseminated encephalomyelitis (ADEM) is a demyelinating disorder of the central nervous system (CNS). Differentiating ADEM from other inflammatory disorders, such as multiple sclerosis, is not always conclusive using conventional MRI. To evaluate longitudinal magnetic resonance spectroscopy (MRS) changes that distinguish ADEM from other inflammatory disorders. MRI/MRS scans were performed in seven patients with ADEM during the acute and chronic phases of the disease. Partial recovery was detected between the acute and chronic phases in choline/creatine ratio. Major elevation of lipids and reduction in myo-inositol/creatine ratio was detected in all patients during the acute phase, followed by a reduction in lipids peak and elevation above normal in myo-inositol/creatine ratio during the chronic phase. Consistent and unique MRS changes in metabolite ratios between the acute and chronic presentations of the disease were found. To the best of our knowledge, these patterns have not been described in other inflammatory disorders and might assist in the early diagnosis of ADEM. (orig.)

  2. Acute Myocardial Infarction: The First Manifestation of Ischemic Heart Disease and Relation to Risk Factors

    Manfroi Waldomiro Carlos

    2002-01-01

    Full Text Available OBJECTIVE: To assess the association between cardiovascular risk factors and acute myocardial infarction as the first manifestation of ischemic heart disease, correlating them with coronary angiographic findings. METHODS: We carried out a cross-sectional study of 104 patients with previous acute myocardial infarction, who were divided into 2 groups according to the presence or absence of angina prior to acute myocardial infarction. We assessed the presence of angina preceding acute myocardial infarction and risk factors, such as age >55 years, male sex, smoking, systemic arterial hypertension, lipid profile, diabetes mellitus, obesity, sedentary lifestyle, and familial history of ischemic heart disease. On coronary angiography, the severity of coronary heart disease and presence of left ventricular hypertrophy were assessed. RESULTS: Of the 104 patients studied, 72.1% were males, 90.4% were white, 73.1% were older than 55 years, and 53.8% were hypertensive. Acute myocardial infarction was the first manifestation of ischemic heart disease in 49% of the patients. The associated risk factors were systemic arterial hypertension (RR=0.19; 95% CI=0.06-0.59; P=0.04 and left ventricular hypertrophy (RR=0.27; 95% CI=0,.8-0.88; P=0.03. The remaining risk factors were not statistically significant. CONCLUSION: Prevalence of acute myocardial infarction as the first manifestation of ischemic heart disease is high, approximately 50%. Hypertensive individuals more frequently have symptoms preceding acute myocardial infarction, probably due to ventricular hypertrophy associated with high blood pressure levels.

  7. Therapeutic Approach to the Management of Pediatric Demyelinating Disease: Multiple Sclerosis and Acute Disseminated Encephalomyelitis.

    Brenton, J Nicholas; Banwell, Brenda L

    2016-01-01

    Acquired pediatric demyelinating diseases manifest acutely with optic neuritis, transverse myelitis, acute disseminated encephalomyelitis, or with various other acute deficits in focal or polyfocal areas of the central nervous system. Patients may experience a monophasic illness (as in the case of acute disseminated encephalomyelitis) or one that may manifest as a chronic, relapsing disease [e.g., multiple sclerosis (MS)]. The diagnosis of pediatric MS and other demyelinating disorders of childhood has been facilitated by consensus statements regarding diagnostic definitions. Treatment of pediatric MS has been modeled after data obtained from clinical trials in adult-onset MS. There are now an increasing number of new therapeutic agents for MS, and many will be formally studied for use in pediatric patients. There are important efficacy and safety concerns regarding the use of these therapies in children and young adults. This review will discuss acute management as well as chronic immunotherapies in acquired pediatric demyelination. PMID:26496907

    Acute necrotizing encephalopathy of childhood (ANEC) is a disease entity seen nearly exclusively in East Asian children that is characterized by multifocal, symmetric lesions involving the thalami, brainstem, cerebellum, and white matter. We present a child who developed dramatic neurologic symptoms following a viral prodrome. Serial MRI examinations demonstrated characteristic lesions of ANEC, while laboratory analyses revealed evidence of acute infection with human herpesvirus-6 (HHV-6). We highlight the MRI findings in both the acute and convalescent phases of ANEC, discuss the implications of neuroimaging on the child's clinical course, and emphasize the integral role of the radiologist in correctly diagnosing this rare disease.

    1999-01-01

    BACKGROUND: There are few epidemiologic data about the risk of acute pancreatitis in chronic inflammatory bowel diseases; we therefore wanted to estimate the risk of a first episode of acute pancreatitis in patients with Crohn's disease and ulcerative colitis in the total Danish population. METHODS......: The study included all patients discharged from Danish hospitals with a diagnosis of Crohn's disease or ulcerative colitis registered in the Danish National Registry of Patients in the period from 1977 to 1992. The first episode of acute pancreatitis was identified in the cohort. The observed number...... of patients with acute pancreatitis was compared with expected numbers on the basis of age, sex, and calendar-specific incidence rates in the general population. RESULTS: Overall, 15,526 patients were discharged and followed up for 112,824 person-years. The standardized incidence ratio (SIR) for...

    2014-01-01

    BACKGROUND: The risk factors for acute episodes of respiratory disease in current and former smokers who do not have COPD are unknown. METHODS: Eight thousand two hundred forty-six non-Hispanic white and black current and former smokers in the Genetic Epidemiology of COPD (COPDGene) cohort had longitudinal follow-up (LFU) every 6 months to determine acute respiratory episodes requiring antibiotics or systemic corticosteroids, an ED visit, or hospitalization. Negative binomial regression was used to determine the factors associated with acute respiratory episodes. A Cox proportional hazards model was used to determine adjusted hazard ratios (HRs) for time to first episode and an acute episode of respiratory disease risk score. RESULTS: At enrollment, 4,442 subjects did not have COPD, 658 had mild COPD, and 3,146 had moderate or worse COPD. Nine thousand three hundred three acute episodes of respiratory disease and 2,707 hospitalizations were reported in LFU (3,044 acute episodes of respiratory disease and 827 hospitalizations in those without COPD). Major predictors included acute episodes of respiratory disease in year prior to enrollment (HR, 1.20; 95% CI, 1.15-1.24 per exacerbation), airflow obstruction (HR, 0.94; 95% CI, 0.91-0.96 per 10% change in % predicted FEV1), and poor health-related quality of life (HR, 1.07; 95% CI, 1.06-1.08 for each 4-unit increase in St. George’s Respiratory Questionnaire score). Risks were similar for those with and without COPD. CONCLUSIONS: Although acute episode of respiratory disease rates are higher in subjects with COPD, risk factors are similar, and at a population level, there are more episodes in smokers without COPD.

    Background: Conventional risk factors for coronary artery disease and myocardial infarction do not explain all of the clinical and epidemiological features of the disease. Periodontal disease is a common bacterial and destructive disorder of oral tissues. Many studies demonstrate close association between chronic periodontitis and development of generalized inflammation, vascular endothelial injury, and atherosclesis. Periodontal disease has been convincingly emerging as an important independ...

  14. Acute bone crises in sickle cell disease: the T1 fat-saturated sequence in differentiation of acute bone infarcts from acute osteomyelitis

    Aim: To prove the hypothesis that acute bone infarcts in sickle cell disease are caused by sequestration of red blood cells (RBCs) in bone marrow, and to evaluate the unenhanced T1 fat-saturated (fs) sequence in the differentiation of acute bone infarction from acute osteomyelitis in patients with sickle-cell disease. Materials and methods: Two studies were undertaken: an experimental study using in-vitro packed red blood cells and normal volunteers, and a retrospective clinical study of 86 magnetic resonance imaging (MRI) studies. For the experimental study containers of packed RBCs were placed between the knees of four healthy volunteers with a saline bag under the containers as an additional control, and were scanned with the pre-contrast T1-fs sequence. Signal intensity (SI) ratios were obtained for packed RBCs:skeletal muscle and packed RBCs:saline. For the clinical study, the SIs of normal bone marrow, packed RBCs, bone and/or soft-tissue lesions, and normal skeletal muscle of 74 patients (86 MRI studies) were measured using unenhanced, T1 fat-saturated MRI. The ratios of the above SIs to normal skeletal muscle were calculated and subjected to statistical analysis. Results: Fifty-one of 86 MRI studies were included in the final analysis. The ratios of SIs for normal bone marrow, packed red cells, bone infarction, acute osteomyelitis, and soft-tissue lesions associated with bone infarct, compared with normal skeletal muscle were (mean ± SD) 0.9 ± 0.2, 2.1 ± 0.7, 1.7 ± 0.5, 1.0 ± 0.3, and 2.2 ± 0.7, respectively. The difference in the ratio of SIs of bone infarcts and osteomyelitis was significant (p = 0.003). The final diagnoses were bone infarction (n = 50), acute osteomyelitis (n = 1), and co-existent bone infarction and osteomyelitis (n = 2). Seven patients who had suspected osteomyelitis underwent image-guided aspiration. Conclusion: Acute bone infarcts in sickle cell disease are caused by sequestration of red blood cells in the bone marrow. The

    Aim: To prove the hypothesis that acute bone infarcts in sickle cell disease are caused by sequestration of red blood cells (RBCs) in bone marrow, and to evaluate the unenhanced T1 fat-saturated (fs) sequence in the differentiation of acute bone infarction from acute osteomyelitis in patients with sickle-cell disease. Materials and methods: Two studies were undertaken: an experimental study using in-vitro packed red blood cells and normal volunteers, and a retrospective clinical study of 86 magnetic resonance imaging (MRI) studies. For the experimental study containers of packed RBCs were placed between the knees of four healthy volunteers with a saline bag under the containers as an additional control, and were scanned with the pre-contrast T1-fs sequence. Signal intensity (SI) ratios were obtained for packed RBCs:skeletal muscle and packed RBCs:saline. For the clinical study, the SIs of normal bone marrow, packed RBCs, bone and/or soft-tissue lesions, and normal skeletal muscle of 74 patients (86 MRI studies) were measured using unenhanced, T1 fat-saturated MRI. The ratios of the above SIs to normal skeletal muscle were calculated and subjected to statistical analysis. Results: Fifty-one of 86 MRI studies were included in the final analysis. The ratios of SIs for normal bone marrow, packed red cells, bone infarction, acute osteomyelitis, and soft-tissue lesions associated with bone infarct, compared with normal skeletal muscle were (mean {+-} SD) 0.9 {+-} 0.2, 2.1 {+-} 0.7, 1.7 {+-} 0.5, 1.0 {+-} 0.3, and 2.2 {+-} 0.7, respectively. The difference in the ratio of SIs of bone infarcts and osteomyelitis was significant (p = 0.003). The final diagnoses were bone infarction (n = 50), acute osteomyelitis (n = 1), and co-existent bone infarction and osteomyelitis (n = 2). Seven patients who had suspected osteomyelitis underwent image-guided aspiration. Conclusion: Acute bone infarcts in sickle cell disease are caused by sequestration of red blood cells in the bone

    Macrophages are crucially involved in the pathophysiology of acute pancreatitis. Soluble CD163 (sCD163) is specifically released from macrophages and systemic levels are increased in inflammatory diseases. Here, sCD163 was measured in serum of 50 patients with acute pancreatitis to find out possible associations with disease activity. Admission levels of systemic sCD163 were nearly three-fold higher in patients with acute pancreatitis compared to controls. In patients sCD163 did not correlate with C-reactive protein and leukocyte count as established markers of inflammation. Levels were not associated with disease severity assessed by the Schroeder score, Balthazar score, Acute Physiology, Age, and Chronic Health Evaluation (Apache) II score and peripancreatic necrosis score. Soluble CD163 was not related to complications of acute pancreatitis. These data show that serum sCD163 is increased in acute pancreatitis indicating activation of macrophages but is not associated with disease severity and outcome. PMID:26209500

    Haze is an atmospheric phenomenon in which dry particulate pollutants obscure the sky. Haze has been associated with chronic diseases, but its relationship with acute diseases is less clear. We aimed to determine the association between haze and acute cardiovascular, cerebrovascular, and respiratory diseases, in order to determine the influence of haze on human health. We compared the number of cases of acute cardiovascular, cerebrovascular, and respiratory diseases in Beijing Emergency Center between 2006 and 2013, with haze data from Beijing Observatory. The relationship between the number of hazy days and the number of cases of the above types of diseases was analyzed using univariate analyses. Both the number of cases and the number of hazy days showed a rising trend. The average number of cases per day for all three diseases was higher on hazy days than on non-hazy days. There was a positive correlation between the number of hazy days and the number of cases, and this correlation showed a hysteretic quality. Haze has an influence on acute cardiovascular (CVDs), cerebrovascular (CBDs), and respiratory system (RSDs) diseases. Haze seems to have an additive effect, since the associations between haze and number of cases were stronger in the following month than in the preceding month. The increasing trend in the number of hazy days might worsen the problem of haze-related diseases. PMID:25292298

  1. FIRST REPORT OF ACUTE CHAGAS DISEASE BY VECTOR TRANSMISSION IN RIO DE JANEIRO STATE, BRAZIL

    Luiz Henrique Conde SANGENIS

    2015-08-01

    Full Text Available SUMMARY Chagas disease (CD is an endemic anthropozoonosis from Latin America of which the main means of transmission is the contact of skin lesions or mucosa with the feces of triatomine bugs infected by Trypanosoma cruzi. In this article, we describe the first acute CD case acquired by vector transmission in the Rio de Janeiro State and confirmed by parasitological, serological and PCR tests. The patient presented acute cardiomyopathy and pericardial effusion without cardiac tamponade. Together with fever and malaise, a 3 cm wide erythematous, non-pruritic, papule compatible with a "chagoma" was found on his left wrist. This case report draws attention to the possible transmission of CD by non-domiciled native vectors in non-endemic areas. Therefore, acute CD should be included in the diagnostic workout of febrile diseases and acute myopericarditis in Rio de Janeiro.

    2016-01-01

    A 70-year-old African American female with a past medical history significant for chronic bilateral shoulder pain and reported sickle cell trait presented with acute-onset bilateral thoracolumbar pain radiating to her left arm. Two days after admission, Hematology was consulted for severely worsening microcytic anemia and thrombocytopenia. Examination of the patient's peripheral blood smear from admission revealed no cell sickling, spherocytes, or schistocytes. Some targeting was noted. A Coombs test was negative. The patient was eventually transferred to the medical intensive care unit in respiratory distress. Hemoglobin electrophoresis confirmed a diagnosis of hemoglobin SC disease. A diagnosis of acute splenic sequestration crisis complicated by acute chest syndrome was crystallized, and red blood cell exchange transfusion was performed. Further research is necessary to fully elucidate the pathophysiology behind acute splenic sequestration crisis, and the role of splenectomy to treat hemoglobin SC disease patients should be better defined.

    2015-10-01

    Mixed connective tissue disease (MCTD) is a rare connective tissue disease frequently involving the lungs. The main characteristic is a systemic sclerosis-like picture of slowly progressing interstitial lung disease consistent with lung fibrosis, while pulmonary arterial hypertension is rare. Herein, we present a case of a newly diagnosed MCTD patient developing life-threatening acute pneumonitis similar to lupus pneumonitis. Previous literature on this exceptionally rare complication of MCTD is reviewed and differential diagnosis and management discussed. PMID:26142172

  10. Psychiatric Disease and Post-Acute Traumatic Brain Injury.

    Zgaljardic, Dennis J; Seale, Gary S; Schaefer, Lynn A; Temple, Richard O; Foreman, Jack; Elliott, Timothy R

    2015-12-01

    Psychiatric disorders are common following traumatic brain injury (TBI) and can include depression, anxiety, and psychosis, as well as other maladaptive behaviors and personality changes. The epidemiologic data of psychiatric disorders post-TBI vary widely, although the incidence and prevalence rates typically are higher than in the general population. Although the experience of psychiatric symptoms may be temporary and may resolve in the acute period, many patients with TBI can experience psychopathology that is persistent or that develops in the post-acute period. Long-term psychiatric disorder, along with cognitive and physical sequelae and greater risk for substance use disorders, can pose a number of life-long challenges for patients and their caregivers, as they can interfere with participation in rehabilitation as well as limit functional independence in the community. The current review of the literature considers the common psychiatric problems affecting individuals with TBI in the post-acute period, including personality changes, psychosis, executive dysfunction, depression, anxiety, and substance misuse. Although treatment considerations (pharmacological and nonpharmacological) are referred to, an extensive description of such protocols is beyond the scope of the current review. The impact of persistent psychiatric symptoms on perceived caregiver burden and distress is also discussed. PMID:25629222

  12. Elemental diet as primary treatment of acute Crohn's disease: a controlled trial.

    O'Moráin, C; Segal, A W; Levi, A J

    1984-06-23

    Acute exacerbations of Crohn's disease are usually treated with prednisolone or potentially more toxic immunosuppressive drugs or by surgery. In pilot studies replacing the normal diet by a protein free elemental diet also induced remission. A controlled trial was therefore conducted in which 21 patients acutely ill with exacerbations of Crohn's disease were randomised to receive either prednisolone 0.75 mg/kg/day or an elemental diet (Vivonex) for four weeks. Assessment at four and 12 weeks showed that the patients treated with the elemental diet had improved as much as and by some criteria more than the steroid treated group. Elemental diet is a safe and effective treatment for acute Crohn's disease. PMID:6428577

    The present study was aimed at describing key computed tomography and magnetic resonance imaging findings in patients with acute abdominal pain derived from pelvic inflammatory disease. Two radiologists consensually selected and analyzed computed tomography and magnetic resonance imaging studies performed between January 2010 and December 2011 in patients with proven pelvic inflammatory disease leading to presentation of acute abdomen. Main findings included presence of intracavitary fluid collections, anomalous enhancement of the pelvic excavation and densification of adnexal fat planes. Pelvic inflammatory disease is one of the leading causes of abdominal pain in women of childbearing age and it has been increasingly been diagnosed by means of computed tomography and magnetic resonance imaging supplementing the role of ultrasonography. It is crucial that radiologists become familiar with the main sectional imaging findings in the diagnosis of this common cause of acute abdomen (author)

    2014-01-01

    In patients with diabetes mellitus, cardiovascular disease is the principal cause of mortality and chest pain is the most frequent symptom in patients with stable and acute coronary artery disease. However, there is little knowledge concerning the pervasiveness of uncommon presentations in diabetics. The symptomatology of acute coronary syndrome, which comprises both pain and non-pain symptoms, may be affected by traditional risk factors such as age, gender, smoking, hypertension, diabetes, and dyslipidemia. Such atypical symptoms may range from silent myocardial ischemia to a wide spectrum of non-chest pain symptoms. Worldwide, few studies have highlighted this under-investigated subject, and this aspect of ischemic heart disease has also been under-evaluated in the major clinical trials. The results of these studies are highly diverse which makes definitive conclusions regarding the spectrum of atypical presentation of acute and even stable chronic coronay artery disease difficult to confirm. This may have a significant impact on the morbidity and mortality of coronary artery disease in diabetics. In this up-to-date review we will try to analyze the most recent studies on the atypical presentations in both acute and chronic ischemic heart disease which may give some emphasis to this under-investigated topic.

  16. Uric acid levels and their relation to incapacities in acute cerebrovascular disease

    Julio López Argüelles

    2010-02-01

    Full Text Available Background: cerebrovascular disease and ischemic cardiopathy can be considered as an epidemic and constitute the first cause of incapacities in developed countries. Multiple studies have shown the association between uric acid levels and cerebrovascular diseases. Objective: To correlate the levels of serum uric acid and incapacities in the acute phase of cerebrovascular disease. Methods: A correlational study was carried out with 217 patients with acute cerebrovascular disease. The patient’s incapacity level was measured by using the Barthel Index and those results were related with the serum uric acid levels and other variables. Results: Male patients have higher levels of uric acid (p=0, 04; r=0, 13. Age and Barthel index were p < 0,001; r = -0, 30 and uric acid levels and Barthel Index were p=0, 03; r=-0, 14. The principal predicting factors of incapacity in the acute phase of cerebrovascular disease were the high levels of uric acid, age and diabetes mellitus. Conclusions: It is shown that the highest is the level of uric acid at advanced age; the greatest is the risk of suffering from incapacity in acute phases of cerebrovascular diseases.

  17. HIDA and ultrasound scans in the diagnosis of acute gall bladder disease

    97 patients with suspected acute gall bladder disease were subjected to cholescintigraphy (HIDA) and ultrasonography (US) to evaluate their diagnostic accuracy in detecting acute cholecystitis (AC). Three patients with non-biliary disease had normal HIDA and sonography scans, while the remaining 94 were operated on within 48 hours of admission to the hospital. Of these 62 (66%) were proved to have AC at operation and on histopathological examination. HIDA scans correctly diagnosed AC in 57 of them (92%), while sonography revealed dilated and oedematous gall bladders, and thus diagnosed AC in 30 patients (48%). (orig.)

    Although ultrasonographic findings of female pelvic mass are frequently reported, those of acute PID are not well established. But differentiation of fluid collection and mass lesion of PID is exactly made by ultrasonography. We analysed the ultrasonographic findings in 26 cases of acute PID having satisfactory operative or histological proofs, examined at Soonchunhyang University Hospital from Oct. 1985 to Feb. 1987. The results were as follows: 1. The age was ranged from 17 years to 53 years of age and the majority was between 21 years and 50 years of age. 2. Ultrasonographic findings are classified to fluid collection in cul de sac 17, tuboovarian abscess, 7 pyosalpix 2, endometritis 1 and normal 2 cases. 3. In cases of pelvic mass formation, their ecnogenecity were cystic form in 6 cases (22%), mixed form in 19 cases (71%), solid form in 2 cases (7%), and shapes were mainly ovoid with irregular, ill-defined margin. The location of mass is unilateral in 17 cases (63%) bilateral in 10 cases (37%)

  1. Acute exacerbation of idiopathic pulmonary fibrosis as the initial presentation of the disease

    K. Sakamoto

    2009-06-01

    Full Text Available The clinical course of patients with idiopathic pulmonary fibrosis (IPF is generally marked by a decline in pulmonary function over time, although recently there is increasing recognition that fatal deterioration from acute exacerbation can occur at any stage. The patient described in the present case study was a 65-yr-old male who presented with exertional dyspnoea and fever of 2 weeks' duration. He had no history of chronic lung disease or physiological or radiological hallmarks of pre-existing disease. He underwent surgical lung biopsy and the histological examination showed a background pattern of usual interstitial pneumonia (UIP with a pattern of focal acute diffuse alveolar damage (DAD in the area where normal lung architecture was preserved. It is notable that the pathological diagnosis of this rapidly progressive interstitial pneumonia was DAD on UIP, which is typically seen in acute exacerbations of IPF. Unusual findings on high-resolution computed tomography scan were also noted. We presume that in this case acute exacerbation developed in the very early course of IPF. Given the possibility that similar cases may have arisen among patients diagnosed with acute interstitial pneumonia or acute respiratory distress syndrome, the histopathology of rapidly progressive interstitial pneumonia may need to be revisited.

    Full Text Available James Galea,1 David Brough21Manchester Academic Health Sciences Center, Brain Injury Research Group, Clinical Sciences Building, Salford Royal Foundation Trust, Salford, UK; 2Faculty of Life Sciences, University of Manchester, AV Hill Building, Manchester, UKAbstract: Acute cerebrovascular disease can affect people at all stages of life, from neonates to the elderly, with devastating consequences. It is responsible for up to 10% of deaths worldwide, is a major cause of disability, and represents an area of real unmet clinical need. Acute cerebrovascular disease is multifactorial with many mechanisms contributing to a complex pathophysiology. One of the major processes worsening disease severity and outcome is inflammation. Pro-inflammatory cytokines of the interleukin (IL-1 family are now known to drive damaging inflammatory processes in the brain. The aim of this review is to discuss the recent literature describing the role of IL-1 in acute cerebrovascular disease and to provide an update on our current understanding of the mechanisms of IL-1 production. We also discuss the recent literature where the effects of IL-1 have been targeted in animal models, thus reviewing potential future strategies that may limit the devastating effects of acute cerebrovascular disease.Keywords: cerebral ischemia, stroke, inflammation, microglia, interleukin-1, caspase-1

    2001-01-01

    OBJECTIVES—Impaired proprioception has been previously reported in patients with Parkinson's disease. It was hypothesised that dopaminergic medications transiently depress proprioception, with amplification of adventitious movements as a result. This study tested for effects on proprioception of dopaminergic drugs, and for associations between such effects and drug induced dyskinesias.
METHODS—In 17 patients with Parkinson's disease, arm proprioception was tested in the ...

    Putta

    2015-03-01

    Full Text Available Sickle cell disease is an autoimmune hemolytic anemia due to abnormal hemoglobin. Sickling of RBCs occur due to abnormal hemoglobin which leads to vaso - occlusive crisis. This disease manifests as hemolytic anemia, acute chest syndrome, stroke, ischemic leg ulcers and nephrotic syndrome. This patient presented with hemolytic anemia, nephrotic syndrome and acute chest syndrome. This case was diagnosed by electrophoresis of h emoglobin and peripheral smear. This patient recovered with blood transfusion, antibiotics, steroids, diuretics and oxygen inhalation. Sickle cell patients have a known predisposition to bacterial infection, particularly pneumococcal infection. The most si gnificant advance in the therapy of sickle cell anemia has been the introduction of hydroxyurea, but hydroxyurea should be considered in patients experiencing repeated episodes of acute chest syndrome. But in this patient as this is first episode, hydroxyu rea was not given and he recovered well.

    2013-01-01

    Full Text Available OBJECTIVE To detect markers for minimal residual disease monitoring based on conventional polymerase chain reaction for immunoglobulin, T-cell receptor rearrangements and the Sil-Tal1 deletion in patients with acute lymphocytic leukemia. METHODS Fifty-nine children with acute lymphocytic leukemia from three institutions in Minas Gerais, Brazil, were prospectively studied. Clonal rearrangements were detected by polymerase chain reaction followed by homo/heteroduplex clonality analysis in DNA samples from diagnostic bone marrow. Follow-up samples were collected on Days 14 and 28-35 of the induction phase. The Kaplan-Meier and multivariate Cox methods were used for survival analysis. RESULTS Immunoglobulin/T-cell receptor rearrangements were not detected in 5/55 children screened (9.0%. For precursor-B acute lymphocytic leukemia, the most frequent rearrangement was IgH (72.7%, then TCRG (61.4%, and TCRD and IgK (47.7%; for T-acute lymphocytic leukemia, TCRG (80.0%, and TCRD and Sil-Tal deletion (20.0% were the most common. Minimal residual disease was detected in 35% of the cases on Day 14 and in 22.5% on Day 28-35. Minimal residual disease on Day 28-35, T-acute lymphocytic leukemia, and leukocyte count above 50 x 109/L at diagnosis were bad prognostic factors for leukemia-free survival in univariate analysis. Relapse risk for minimal residual disease positive relative to minimal residual disease negative children was 8.5 times higher (95% confidence interval: 1.02-70.7. CONCLUSION Immunoglobulin/T-cell receptor rearrangement frequencies were similar to those reported before. Minimal residual disease is an independent prognostic factor for leukemia-free survival, even when based on a non-quantitative technique, but longer follow-ups are needed.

    1990-07-01

    We report on 2 patients who developed an acute febrile neutrophilic dermatosis (Sweet's syndrome) and erythema nodosum in association with Crohn's disease. The first patient showed symmetrical painful erythemas on her cheeks after hemicolectomy. Additionally, red painful nodules appeared on her lower legs. The second patient disclosed typical Sweet's syndrome-like lesions with pustules and plaques on her face, scalp and extremities after activation of Crohn's disease. Simultaneously, erythema nodosum-like lesions appeared on her lower legs. PMID:2144848

  15. Managing the acute painful episode in sickle cell disease

    B. Kaya

    2011-12-01

    Full Text Available Sickle cell pain is a complex but frequently experienced symptom. Acute painful events in children can be managed effectively in the community with appropriate support and education. If hospital management is required, rapid access to a consistent, reliable and safe analgesic pathway is recommended to ensure a good standard of care. Use of oral opiates in addition to short acting easily administrable forms of analgesia and strict adherence to protocoled monitoring will enable the acute event to be well managed and the negative pain experience minimised. An important part of the outpatient evaluation is determining the impact pain events are having on the child’s quality of life. Addressing psycho-social aspects, defining and modifying precipitating factors, if any are identified, and having a holistic approach to pain management is helpful. Education and use of self-management techniques can also be productive. Use of sickle modifying interventions such as hydroxycarbamide therapy or transfusion therapy can have a significant impact on reducing the severity and frequency of the acute pain event. 镰状细胞疼痛是一种复杂的常发症。 通过适当的支助和教育,儿童急性疼痛症可以得到有效抑制。 如果需要在医院进行护理,患者应尽快寻求持续可靠且安全的止痛方式,确保良好的护理。 除采取作用短、管理方便的止痛治疗和遵守监测协议之外,患者还需口服鸦片剂,这样,急性症状可以得到良好的抑制,还可尽量减轻疼痛感。 诊断门诊病人一个重要的部分就是确定疼痛症对患儿生活质量产生的影响。 问询生理社会方面问题,确定和修改诱发因子(如有),并整体分析可行的疼痛护理方法。 教育和使用个人护理法也很有效果。 采用镰状细胞修改干预法,例如羟基尿素疗法或输液疗法,对减轻急性疼痛症和减少发作频率有着显著效果。

  16. ACUTE PHASE REACTANCTS IN PERICARDIAL FLUID ARE INDICATORS OF CORONARY ARTERY DISEASE

    Yılmaz Mehmet Ali

    2012-12-01

    Full Text Available Inflammation in formation of atherosclerosis, and acute phase reactants in the site of inflammation have major functions. Thus, do the acute phase reactants constitute the biggest risk factor for coronary artery disease? 55 patients are included in the study. Patients with coronary artery bypass surgery are included in Group I (38 patients and patients with valve operation are included in Group II (17 patients. CABG patients are further divided into two sub-groups as on-pump and off-pump. In both groups, homocystein, high sensitivity C reactive protein, ceruloplasmin, lipoprotein A and serum amyloid A protein levels are analyzed from blood and pericardial fluid. In patients with coronary artery disease, the measured high specific C- reactive protein levels from blood and pericardial fluid are found to be significantly high compared to patients with valve operation.Homocystein levels of pericardial fluids of patients with CABG are found to be higher than patients with valve operation and it is confirmed that the situation is correlated with blood homocystein levels. Although there are lots studies expressing the relation between coronary artery disease and lipoprotein A, ceruloplasmin and serum amyloid A protein levels; no significant difference for those parameters was obtained in our study. We determined that other phase reactants are higher in patients with coronary artery disease, in accordance with the literature. We aimed to state that acute phase reactants not only increase as a result of disease, but their levels are also elevated beforehand, as an indicator of the disease.

  17. Treatment disparities in acute coronary syndromes, heart failure, and kidney disease.

    McCullough, Peter A; Maynard, Robert C

    2011-01-01

    It has been consistently observed that patients with renal dysfunction have more premature, severe, complicated, and fatal cardiovascular disease than age- and sex-matched individuals with normal renal function. There have been 4 major explanations for this finding: (1) positive confounding by third variables associated with chronic kidney disease (CKD), including diabetes mellitus and hypertension; (2) therapeutic nihilism or lesser use of beneficial therapies in CKD; (3) greater toxicities of therapies, such as bleeding from anticoagulants or contrast-induced kidney injury; (4) biological factors which result directly from CKD that work to promote and accelerate cardiovascular disease. In this paper, we focus on the issue of treatment disparities or therapeutic nihilism and its contribution to poor outcomes in the setting of acute coronary syndromes and acutely decompensated heart failure. This issue is important because if we can overcome barriers to the utilization of beneficial treatments, then clinical outcomes should improve over time. PMID:21625092

  20. Acute chondrolysis complicating Legg-Calve-Perthes disease

    Of 270 children with Legg-Calve-Perthes (LCP) disease, roentgenographic evidence of chondrolysis was noted in 12 (4.5%) within one year after diagnosis and appropriate management. Only in six hips of these 12 patients did the retrospective clinical, histological, and orthopedic findings fulfill the diagnostic requirements for chondrolysis. Sequential roentgenographic findings included initial periarticular osteoporosis and subchondral cortical irregularities, subsequent narrowing of the joint space, premature fusion of the growth plate, and eventual development of degenerative arthritis. The early roentgenographic recognition of chondrolysis is emphasized because it has an untoward effect on the prognosis of LCP and should therefore prompt a different orthopedic approach. (orig.)

  1. The burden of acute disease in Mahajanga, Madagascar - a 21 month study.

    Vijay C Kannan

    Full Text Available Efforts to develop effective and regionally-appropriate emergency care systems in sub-Saharan Africa are hindered by a lack of data on both the burden of disease in the region and on the state of existing care delivery mechanisms. This study describes the burden of acute disease presenting to an emergency unit in Mahajanga, Madagascar.Handwritten patient registries on all emergency department patients presenting between 1 January 2011 and 30 September 2012 were reviewed and data entered into a database. Data included age, sex, diagnosis, and disposition. We classified diagnoses into Clinical Classifications Software (CCS multi-level categories. The population was 53.5% male, with a median age of 31 years. The five most common presenting conditions were 1 Superficial injury; contusion, 2 Open wounds of head; neck; and trunk, 3 Open wounds of extremities, 4 Intracranial injury, and 5 Unspecified injury and poisoning. Trauma accounted for 48%, Infectious Disease for 15%, Mental Health 6.1%, Noncommunicable 29%, and Neoplasms 1.2%. The acuity seen was high, with an admission rate of 43%. Trauma was the most common reason for admission, representing 19% of admitted patients.This study describes the burden of acute disease at a large referral center in northern Madagascar. The Centre Hôpitalier Universitaire de Mahajanga sees a high volume of acutely ill and injured patients. Similar to other reports from the region, trauma is the most common pathology observed, though infectious disease was responsible for the majority of adult mortality. Typhoid fever other intestinal infections were the most lethal CCS-coded pathologies. By utilizing a widely understood classification system, we are able to highlight contrasts between Mahajanga's acute and overall disease burden as well as make comparisons between this region and the rest of the globe. We hope this study will serve to guide the development of context-appropriate emergency medicine systems in the

  2. The prevalence of natural health product use in patients with acute cardiovascular disease.

    Aws Alherbish

    Full Text Available BACKGROUND: Natural health products (NHP use may have implications with respect to adverse effects, drug interactions and adherence yet the prevalence of NHP use by patients with acute cardiovascular disease and the best method to ascertain this information is unknown. OBJECTIVE: To identify the best method to ascertain information on NHP, and the prevalence of use in a population with acute cardiovascular disease. METHODS: Structured interviews were conducted with a convenience sample of consecutive patients admitted with acute cardiovascular disease to the University of Alberta Hospital during January 2009. NHP use was explored using structured and open-ended questions based on Health Canada's definition of NHP. The medical record was reviewed, and documentation of NHP use by physicians, nurses, and pharmacists, compared against the gold-standard structured interview. RESULTS: 88 patients were interviewed (mean age 62 years, standard deviation [SD 14]; 80% male; 41% admitted for acute coronary syndromes. Common co-morbidities included hypertension (59%, diabetes (26% and renal impairment (19%. NHP use was common (78% of patients and 75% of NHP users reported daily use. The category of NHP most commonly used was vitamins and minerals (73% followed by herbal products (20%, traditional medicines including Chinese medicines (9%, homeopathic preparations (1% and other products including amino acids, essential fatty acids and probiotics (35%. In a multivariable model, only older age was associated with increased NHP use (OR 1.5 per age decile [95%CI 1.03 to 2.2]. When compared to the interview, the highest rate of NHP documentation was the pharmacist history (41%. NHP were documented in 22% of patients by the physician and 19% by the nurse. CONCLUSIONS: NHP use is common in patients admitted with acute cardiovascular disease. However, health professionals do not commonly identify NHP as part of the medication profile despite its potential importance

    Cushing's disease is usually associated with higher mortality rate, especially from cardiovascular causes. Development or exacerbation of autoimmune or inflammatory diseases is known to occur in patients with hypercortisolism after cure. We report for the first time a 34-year old woman with a psychiatric background, who developed four months after the surgical cure of Cushing's disease an acute disseminated encephalomyelitis (ADEM) presenting initially as a psychiatric illness. We hypothesize that the recent correction of hypercortisolism triggered ADEM and that the atypical presentation, responsible for diagnosis delay, led to the death of this patient. PMID:20850107

    2006-01-01

    Infliximab is a potent anti-TNF antibody, which is used with great success in Crohn's disease patients. Since its release in clinical practice, several adverse reactions have been observed. The interest in possible consequences of its administration is still high because of the recent introduction of the drug for the long-term maintenance therapy of refractory luminal and fistulizing Crohn's disease. We present a case of acute coronary syndrome (non-STEMI) in a patient with corticoid resistant Crohn's disease after his first dose of infliximab. By reviewing the scant articles that exist in the literature on this topic we made an effort to delineate the possible mechanisms of this phenomenon.

  5. Immune Mechanisms of Mesenchymal Stem Cell Therapy for Acute Graft versus Host Disease

    Even, Caroline; Bastuji-Garin, Sylvie; Hicheri, Yosr; Pautas, Cécile; Botterel, Francoise; Maury, Sébastien; Cabanne, Ludovic; Bretagne, Stéphane; Cordonnier, Catherine

    2010-01-01

    Patients with acute leukemia who initially survive invasive fungal disease must receive chemotherapy or go on to transplant. Many centers change subsequent chemotherapy to decrease the risk of fungal reactivation. This case-control study compared acute leukemia patients (n=28) who developed a proven or probable fungal disease and survived four weeks later, to patients who did not (n=78), and assessed the impact of fungal disease on the chemotherapy regimens, and overall and event-free survival.

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

    Florent Malard

    2014-01-01

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

  8. The epidemiology and outcome of acute renal failure and the impact on chronic kidney disease.

    Block, Clay A; Schoolwerth, Anton C

    2006-01-01

    Acute renal failure (ARF) is a common condition, especially among the critically ill, and confers a high mortality. Recent publications have highlighted changes in the epidemiology and improvement in mortality that was long thought to be static despite improvements in clinical care. The incidence of ARF is increasing. Efforts, such as the Acute Dialysis Quality Initiative, are being undertaken to establish a consensus definition of ARF, and to distinguish between varying degrees of acute kidney injury. Data are emerging to allow comparison of the epidemiology of ARF across institutions internationally. There is ongoing recognition of the important interaction between ARF and chronic kidney disease. Two brief case reports are offered to help frame the context and clinical impact of this disorder, followed by a review of some of the recent literature that addresses these points. PMID:17150044

  9. Electrocardiographic abnormalities in acute cerebrovascular events in patients with/without cardiovascular disease

    Mansoureh Togha

    2013-01-01

    Full Text Available Objectives: Electrocardiographic (ECG changes are reported frequently after acute strokes. It seems that cardiovascular effects of strokes are modulated by concomitant or pre-existent cardiac diseases, and are also related to the type of cerebrovascular disease and its localization. We aimed to determine the pattern of ECG changes associated with pathophysiologic categories of acute stroke among patients with/without cardiovascular disease and to determine if specific ECG changes are related to the location of the lesion. Materials and Methods : The electrocardiographic records of 361 patients with acute stroke were studied to assess the relative frequencies of ECG abnormalities among the pathophysiologic categories of stroke. Results: In the present study, the most common ECG abnormalities associated with stroke were T-wave abnormalities, prolonged QTc interval and arrhythmias, which were respectively found in 39.9%, 32.4%, and 27.1% of the stroke patients and 28.9%, 30.7%, and 16.2 of the patients with no primary cardiac disease. We observed that other ECG changes comprising pathologic Q- wave, ST-segment depression, ST-segment elevation, and prominent U wave may also occur in selected or non-selected stroke patients; thereby simulate an acute myocardial injury. We observed an increased number of patients with abnormal T-wave and posterior fossa bleedings and more rhythm disturbances for ischemic lesions, localized in the anterior fossa. Conclusion: Ischemia-like ECG changes and arrhythmias are frequently seen in stroke patients, even in those with no history or signs of primary heart disease, which support a central nervous system origin of these ECG abnormalities. Further study is necessary to better define the brain-heart interaction.

  10. The fecal microbiome in dogs with acute diarrhea and idiopathic inflammatory bowel disease.

    Jan S Suchodolski

    Full Text Available BACKGROUND: Recent molecular studies have revealed a highly complex bacterial assembly in the canine intestinal tract. There is mounting evidence that microbes play an important role in the pathogenesis of acute and chronic enteropathies of dogs, including idiopathic inflammatory bowel disease (IBD. The aim of this study was to characterize the bacterial microbiota in dogs with various gastrointestinal disorders. METHODOLOGY/PRINCIPAL FINDINGS: Fecal samples from healthy dogs (n = 32, dogs with acute non-hemorrhagic diarrhea (NHD; n = 12, dogs with acute hemorrhagic diarrhea (AHD; n = 13, and dogs with active (n = 9 and therapeutically controlled idiopathic IBD (n = 10 were analyzed by 454-pyrosequencing of the 16S rRNA gene and qPCR assays. Dogs with acute diarrhea, especially those with AHD, had the most profound alterations in their microbiome, as significant separations were observed on PCoA plots of unweighted Unifrac distances. Dogs with AHD had significant decreases in Blautia, Ruminococcaceae including Faecalibacterium, and Turicibacter spp., and significant increases in genus Sutterella and Clostridium perfringens when compared to healthy dogs. No significant separation on PCoA plots was observed for the dogs with IBD. Faecalibacterium spp. and Fusobacteria were, however, decreased in the dogs with clinically active IBD, but increased during time periods of clinically insignificant IBD, as defined by a clinical IBD activity index (CIBDAI. CONCLUSIONS: Results of this study revealed a bacterial dysbiosis in fecal samples of dogs with various GI disorders. The observed changes in the microbiome differed between acute and chronic disease states. The bacterial groups that were commonly decreased during diarrhea are considered to be important short-chain fatty acid producers and may be important for canine intestinal health. Future studies should correlate these observed phylogenetic differences with functional changes in the intestinal

  11. Respiratory protection and emerging infectious diseases: lessons from severe acute respiratory syndrome

    John H. Lange

    2005-01-01

    @@ The severe acute respiratory syndrome (SARS) that emerged 2002-2003 and apparently again 2004 (reported by the news media on December 27, 2003) as the first confirmed case by the World Health Organization (WHO)1,2 raised awareness of emerging infectious diseases.3 Every year there are both new and old infectious diseases emerging as potential pandemic agents.4-6 However, few of these diseases receive the public attention and concern expressed as occurred during the emergence of SARS. Much of this concern was a result of the rapid spread of the novel coronavirus (CoV) to different regions of the world and its high infectivity, especially for health care workers (HCW).3 In many ways, the high percent of HCW infected is a warning of the potential hazards of old and emerging infectious diseases.6 However, SARS was not the only disease (e.g. Monkeypox) that emerged in 2003,3 rather it received the greatest attention.

  12. Radiodiagnosis programs for the recognition of acute surgical diseases of the abdominal organs, retroperitoneal space and complications thereof

    Program for complex use of X-ray and ultrasonic diagnostic methods, X-ray computerized tomography was worked out in diseases of the abdominal organs, retroperitoneal space. Creation of such program was necessary due to acute surgical intervention in diseases of these organs (1750 patients with clinical picture of acute abdomen, 1350 patients with acute diseases of abdomen cavity organs). Obtaining of momentary information for diagnosis is required in most of cases. Schemes are suggested for complex usage of these diagnostic methods in different pathology, clinical symptoms, severity in patient state, technical possibilities of medical establishments

  13. Subacute radiation dermatitis: a histologic imitator of acute cutaneous graft-versus-host disease

    The histopathologic changes of radiation dermatitis have been classified either as early effects (necrotic keratinocytes, fibrin thrombi, and hemorrhage) or as late effects (vacuolar changes at the dermal-epidermal junction, atypical radiation fibroblasts, and fibrosis). Two patients, one exposed to radiation therapeutically and one accidentally, are described. Skin biopsy specimens showed an interface dermatitis characterized by numerous dyskeratotic epidermal cells with lymphocytes in close apposition (satellite cell necrosis); that is, the epidermal changes were similar to those in acute graft-versus-host disease. Because recipients of bone marrow transplants frequently receive total body irradiation as part of their preparatory regimen, the ability of radiation to cause persistent epidermal changes similar to those in acute graft-versus-host disease could complicate the interpretation of posttransplant skin biopsy specimens

  16. Study on the Relationship between Plasma Homocysteine and Acute Cerebral Vascular Disease

    2000-01-01

    The levels of plasma homocysteine were determined by using high-performance liquid chromatographic method. It was found that plasma homocysteine levels were significantly higher in the patients with stroke than that in the controls. There was no correlation between plasma homocysteine levels and hypertension, smoking, concentrations of blood glucose or hypertriglyceridesemia. It was suggested that hyperhomocysteinemia may be an independent risk factor for acute cerebral vascular disease.

    2014-04-01

    We propose a clinical pathway of acute exacerbations of chronic obstructive pulmonary disease (AECOPD) based on state machine. Clinical event-driven response was utilized to control workflow execution of the AECOPD clinical pathway. By comparison with the traditional clinical pathway management, clinical numerical results showed that the proposed method was better in hospitalization days, average hospitalization expense and aberration rate, and better handled the variability in the AECOPD clinical pathway execution.

    In this study, we investigated the mechanism(s) of mitochondrial functional decline in acute Chagas’ disease. Our data show a substantial decline in respiratory complex activities (39 to 58%) and ATP (38%) content in Trypanosoma cruzi-infected murine hearts compared with normal controls. These metabolic alterations were associated with an approximately fivefold increase in mitochondrial reactive oxygen species production rate, substantial oxidative insult of mitochondrial membranes and respir...

    2015-09-01

    Full Text Available Acute metabolic decompensation in maple syrup urine disease can occur during intercurrent illness and is a medical emergency. A handful of reports in the medical literature describe the use of peritoneal dialysis and haemodialysis as therapeutic inventions. We report the only patient from our centre to have haemodialysis performed in this setting. Combined with dietary BCAA restriction and calorific support, haemodialysis allows rapid reduction in plasma leucine concentrations considerably faster than conservative methods.

    Farber Harrison W; Klings Elizabeth S

    2001-01-01

    Abstract Acute chest syndrome (ACS) of sickle cell disease (SCD) is characterized pathologically by vaso-occlusive processes that result from abnormal interactions between sickle red blood cells (RBCs), white blood cells (WBCs) and/or platelets, and the vascular endothelium. One potential mechanism of vascular damage in ACS is by generation of oxygen-related molecules, such as superoxide (O2-), hydrogen peroxide (H2O2), peroxynitrite (ONOO-), and the hydroxyl (•OH) radical. The present review...

    2008-01-01

    Acute liver failure (ALF) due to Wilson disease (WD) is invariably fatal without emergency liver transplantation. Therefore, rapid diagnosis of WD should aid prompt transplant listing. To identify the best method for diagnosis of ALF due to WD (ALF-WD), data and serum were collected from 140 ALF...... patients (16 with WD), 29 with other chronic liver diseases and 17 with treated chronic WD. Ceruloplasmin (Cp) was measured by both oxidase activity and nephelometry and serum copper levels by atomic absorption spectroscopy. In patients with ALF, a serum Cp <20 mg/dL by the oxidase method provided a...

  15. Pharmacologic prophylaxis regimens for acute graft-versus-host disease: past, present and future.

    Ram, Ron; Storb, Rainer

    2013-08-01

    Abstract Acute graft-versus-host disease (GVHD) has compromised and continues to compromise the benefits associated with allogeneic hematopoietic cell transplant to cure malignant and non-malignant diseases. Pharmacologic interventions to prevent GVHD have emerged as a major objective of research in the immunology and transplant fields. A better understanding of the pathobiology behind the GVHD process has led the way to novel approaches and medications. Here we review the present arsenal of medications used to prevent GVHD, focusing on past experience and the current evidence, and discuss future potential targets. PMID:23278640

  16. Kikuchi-Fujimoto disease: an unusual association with acute renal failure

    Amanda Feliciano da Silva

    2010-12-01

    Full Text Available Kikuchi-Fujimoto disease, also known as histiocytic necrotizing lymphadenitis of unknown etiopathogenesis, is a self-limited disease which frequently appears as feverish lymphadenomegaly, thus creating the need for differential diagnosis with lymphoma, systemic lupus erythematosus (SLE, infectious mononucleosis, cat-scratch disease, and toxoplasmosis with lymphonodal impairment. However, there are cases in which it may evolve with complications such as aseptic meningitis, cerebellar ataxia, and aseptic myocarditis. We are presenting a case of a 24-year-old man who had an initial picture of arthralgia, evening fever and adenomegaly. Kikuchi disease was diagnosed through lymph node biopsy with immunohistochemistry and evolves with severe systemic manifestations, such as pericarditis with cardiac tamponade, pneumonitis, hepatitis, and acute kidney failure - the latter has not been reported in literature yet. There was significant improvement of the clinical picture with prednisone

  17. Adalimumab-induced acute interstitial lung disease in a patient with rheumatoid arthritis

    Olivia Meira Dias

    2014-01-01

    Full Text Available The use of immunobiological agents for the treatment of autoimmune diseases is increasing in medical practice. Anti-TNF therapies have been increasingly used in refractory autoimmune diseases, especially rheumatoid arthritis, with promising results. However, the use of such therapies has been associated with an increased risk of developing other autoimmune diseases. In addition, the use of anti-TNF agents can cause pulmonary complications, such as reactivation of mycobacterial and fungal infections, as well as sarcoidosis and other interstitial lung diseases (ILDs. There is evidence of an association between ILD and the use of anti-TNF agents, etanercept and infliximab in particular. Adalimumab is the newest drug in this class, and some authors have suggested that its use might induce or exacerbate preexisting ILDs. In this study, we report the first case of acute ILD secondary to the use of adalimumab in Brazil, in a patient with rheumatoid arthritis and without a history of ILD.

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

    Effective immunosuppression is mandatory to prevent graft-versus-host disease and to achieve a successful clinical outcome of hematopoietic stem cell transplantation. Here we tested whether germline single nucleotide polymorphisms in 20 candidate genes related to methotrexate and cyclosporine metabolism and activity influence the incidence of graft-versus-host disease in patients who undergo stem cell transplantation for hematologic disorders. Recipient genetic status of the adenosine triphosphate-binding cassette sub-family C1 and adenosine triphosphate-binding cassette sub-family C2 transporters, 5-aminoimidazole-4-carboxamide ribonucleotide formyltransferase/ inosine monophosphate cyclohydrolase within the methotrexate pathway, and nuclear factor of activated T cells (cytoplasmic 1) loci exhibit a remarkable influence on severe acute graft-versus-host disease prevalence. Indeed, an increased risk of acute graft-versus-host disease was observed in association with single nucleotide polymorphisms located in 5-aminoimidazole-4-carboxamide ribonucleotide formyltransferase/inosine monophosphate cyclohydrolase (hazard ratio=3.04; P=0.002), nuclear factor of activated T cells (cytoplasmic 1) (hazard ratio=2.69; P=0.004), adenosine triphosphate-binding cassette sub-family C2 (hazard ratio=3.53; P=0.0018) and adenosine triphosphate-binding cassette sub-family C1 (hazard ratio=3.67; P=0.0005). While donor single nucleotide polymorphisms of dihydrofolate reductase and solute carrier family 19 (member 1) genes are associated with a reduced risk of acute graft-versus-host disease (hazard ratio=0.32-0.41; P=0.0009-0.008), those of nuclear factor of activated T cells (cytoplasmic 2) are found to increase such risk (hazard ratio=3.85; P=0.0004). None of the tested single nucleotide polymorphisms was associated with the occurrence of chronic graft-versus-host disease. In conclusion, by targeting drug-related biologically relevant genes, this work emphasizes the potential role of

  2. Circulating microbial products and acute phase proteins as markers of pathogenesis in lymphatic filarial disease.

    R Anuradha

    Full Text Available Lymphatic filariasis can be associated with development of serious pathology in the form of lymphedema, hydrocele, and elephantiasis in a subset of infected patients. Dysregulated host inflammatory responses leading to systemic immune activation are thought to play a central role in filarial disease pathogenesis. We measured the plasma levels of microbial translocation markers, acute phase proteins, and inflammatory cytokines in individuals with chronic filarial pathology with (CP Ag+ or without (CP Ag- active infection; with clinically asymptomatic infections (INF; and in those without infection (endemic normal [EN]. Comparisons between the two actively infected groups (CP Ag+ compared to INF and those without active infection (CP Ag- compared to EN were used preliminarily to identify markers of pathogenesis. Thereafter, we tested for group effects among all the four groups using linear models on the log transformed responses of the markers. Our data suggest that circulating levels of microbial translocation products (lipopolysaccharide and LPS-binding protein, acute phase proteins (haptoglobin and serum amyloid protein-A, and inflammatory cytokines (IL-1β, IL-12, and TNF-α are associated with pathogenesis of disease in lymphatic filarial infection and implicate an important role for circulating microbial products and acute phase proteins.

    In both human and veterinary medicine, diagnosing and staging renal disease can be difficult. Measurement of glomerular filtration rate is considered the gold standard for assessing renal function but methods for its assessment can be technically challenging and impractical. The main parameters used to diagnose acute and chronic kidney disease include circulating creatinine and urea concentrations, and urine-specific gravity. However, these parameters can be insensitive. Therefore, there is a need for better methods to diagnose and monitor patients with renal disease. The use of renal biomarkers is increasing in human and veterinary medicine for the diagnosis and monitoring of acute and chronic kidney diseases. An ideal biomarker would identify site and severity of injury, and correlate with renal function, among other qualities. This article will review the advantages and limitations of renal biomarkers that have been used in dogs and cats, as well as some markers used in humans that may be adapted for veterinary use. In the future, measuring a combination of biomarkers will likely be a useful approach in the diagnosis of kidney disorders. PMID:24152019

  5. Recurrent acute pancreatitis and cholangitis in a patient with autosomal dominant polycystic kidney disease

    Kambiz Yazdanpanah

    2013-01-01

    Full Text Available Autosomal dominant polycystic kidney disease (ADPKD is an inherited disorder associated with multiple cyst formation in the different organs. Development of pancreatic cyst in ADPKD is often asymptomatic and is associated with no complication. A 38-year-old man with ADPKD was presented with six episodes of acute pancreatitis and two episodes of cholangitis in a period of 12 months. Various imaging studies revealed multiple renal, hepatic and pancreatic cysts, mild ectasia of pancreatic duct, dilation of biliary system and absence of biliary stone. He was managed with conservative treatment for each attack. ADPKD should be considered as a potential risk factor for recurrent acute and/or chronic pancreatitis and cholangitis.

    We report a case of neonatal herpes simplex virus (HSV)-1 central nervous system disease with bilateral acute retinal necrosis (ARN). An infant was presented at 17 days of age with focal seizures. Cerebrospinal fluid polymerase chain reaction was positive for HSV-1 and brain magnetic resonance imaging showed cerebritis. While receiving intravenous acyclovir therapy, the infant developed ARN with vitreous fluid polymerase chain reaction positive for HSV-1 necessitating intravitreal foscarnet therapy. This is the first reported neonatal ARN secondary to HSV-1 and the first ARN case presenting without external ocular or cutaneous signs. Our report highlights that infants with neonatal HSV central nervous system disease should undergo a thorough ophthalmological evaluation to facilitate prompt diagnosis and immediate treatment of this rapidly progressive sight-threatening disease.

  8. Diagnosis of acute radiation disease by Enzyme Immune-Assay (EIA)

    Diagnosis of the acute radiation disease by the method of immune enzyme assay is a simple and efficient tool of evaluating and biological dosimetry and forecasting of development of the acute radiation defeats as at group of population so at individuals locating in the zone polluted by the radiation. We use as biological markers the group of essential radiotoxins - high molecular mass glycoprotein ( molecular mass - 200 - 250 kDa ) - radiation antigens (S.D.R. - specific radiation determinant ) accumulated in the lymphoid system, with epitopes specific to each form of radiation syndrome, after animals have been irradiated in doses inducing the development of the cerebral (1), toxic ( 2), gastrointestinal ( 3 ) and typical ( 4 ) forms of acute radiation sickness. These two phenomena allowed us to develop a technologies for diagnosis, prophylaxis and therapy of radiation disease - enzyme immune assay ( EIA ), anti radiation vaccine, anti radiation serum, method of immune - lymph - plasma-sorption. The important first step in effectiveness of therapy is an accurate assessment of severity of disease in early period after irradiation. The ideal markers for early and accurate assessment is high weight glycoprotein with specifics radiation induced features (S.D.R.) mentioned above. This biology active substance isolated from lymph can induct the symptoms of radiation syndrome without previously radiation when it is administrated intra-muscularly or intravenously to healthy animals. Enzyme immune assay (EIA) allowed researchers to indicate the significant levels of different forms of S.D.R. in peripheral blood of animals in first 24 hours after radiation. Indication of high level of S.D.R. -1 allowed to forecast a fast development of cerebral form of acute radiation disease. Determination of high levels of S.D.R.-2, S.D.R.-3 and S.D.R.-4 in peripheral blood allowed to recognize early periods of toxic, gastrointestinal and typical forms of acute radiation sickness

The objective of the present study was to determine the frequency and clinical relevance of HBoV infection in adult patients with acute exacerbation of chronic obstructive pulmonary disease (AE-COPD.Methods: We retrospectively tested 212 COPD patients, 141 (66.5% with AE-COPD and 71 (33.5% with stable disease, of whom nasal lavage and induced sputum had been obtained for the presence of HBoV deoxyribonucleic acid (DNA. The specificity of positive polymerase chain reaction results was confirmed by sequencing.Results: Two hundred two of 212 patients for whom PCR results were available both for nasal lavage and induced sputum samples were eligible for data analysis. HBoV DNA was detected in three patients (1.5%. Of those, only one patient had AE-COPD. Thus, the frequency of HBoV infection demonstrated to be low in both AE-COPD (0.8% and stable COPD (2.9%. HBoV was found in two sputum and one nasal lavage sample in different patients, respectively. Sequencing revealed >99% sequence identity with the reference strain.Conclusion: HBoV detection was infrequent. Since we detected HBoV in both upper and lower respiratory tract specimens and in AE-COPD as well as stable disease, a major role of HBoV infection in adults with AE-COPD is unlikely

    Exercise training is an effective way to improve exercise capacity in chronic kidney disease (CKD), but the underlying mechanisms are only partly understood. In healthy subjects (HS), microRNA (miRNA or miR) are dynamically regulated following exercise and have, therefore, been suggested as regulators of cardiovascular adaptation to exercise. However, these effects were not studied in CKD before. The effect of acute exercise (i.e., an acute exercise bout) was assessed in 32 patients with CKD and 12 age- and sex-matched HS (study 1). miRNA expression in response to chronic exercise (i.e., a 3-mo exercise training program) was evaluated in 40 CKD patients (study 2). In a subgroup of study 2, the acute-exercise induced effect was evaluated at baseline and at follow-up. Plasma levels of a preselected panel miRNA, involved in exercise adaptation processes such as angiogenesis (miR-126, miR-210), inflammation (miR-21, miR-146a), hypoxia/ischemia (miR-21, miR-210), and progenitor cells (miR-150), were quantified by RT-PCR. Additionally, seven miRNA involved in similar biological processes were quantified in the subgroup of study 2. Baseline, studied miRNA were comparable in CKD and HS. Following acute exercise, miR-150 levels increased in both CKD (fold change 2.12 ± 0.39, P = 0.002; and HS: fold change 2.41 ± 0.48 P = 0.018, P for interaction > 0.05). miR-146a acutely decreased in CKD (fold change 0.92 ± 0.13, P = 0.024), whereas it remained unchanged in HS. Levels of miR-21, miR-126, and miR-210 remained unaltered. Chronic exercise did not elicit a significant change in the studied miRNA levels. However, an acute exercise-induced decrease in miR-210 was observed in CKD patients, only after training (fold change 0.76 ± 0.15). The differential expression in circulating miRNA in response to acute and chronic exercise may point toward a physiological role in cardiovascular adaptation to exercise, also in CKD. PMID:26475583

    Full Text Available Abstract Background Asthma and sickle cell disease are common conditions that both may result in pulmonary complications. We hypothesized that children with sickle cell disease with concomitant asthma have an increased incidence of vaso-occlusive crises that are complicated by episodes of acute chest syndrome. Methods A 5-year retrospective chart analysis was performed investigating 48 children ages 3–18 years with asthma and sickle cell disease and 48 children with sickle cell disease alone. Children were matched for age, gender, and type of sickle cell defect. Hospital admissions were recorded for acute chest syndrome, cerebral vascular accident, vaso-occlusive pain crises, and blood transfusions (total, exchange and chronic. Mann-Whitney test and Chi square analysis were used to assess differences between the groups. Results Children with sickle cell disease and asthma had significantly more episodes of acute chest syndrome (p = 0.03 and cerebral vascular accidents (p = 0.05 compared to children with sickle cell disease without asthma. As expected, these children received more total blood transfusions (p = 0.01 and chronic transfusions (p = 0.04. Admissions for vasoocclusive pain crises and exchange transfusions were not statistically different between cases and controls. SS disease is more severe than SC disease. Conclusions Children with concomitant asthma and sickle cell disease have increased episodes of acute chest syndrome, cerebral vascular accidents and the need for blood transfusions. Whether aggressive asthma therapy can reduce these complications in this subset of children is unknown and requires further studies.

    During a recent nosocomial outbreak, 20 critically ill patients with acute Legionnaires' disease were admitted to the intensive care unit of Hopital Bichat, Paris. Pulmonary specimens were obtained at surgery or immediately after death in 12 patients and were examined by light, immunofluorescent, and electron microscopy. Five of these 12 patients showed evidence of pulmonary fibrosis. In all of these five patients, infection with Legionella pneumophila was evidenced by bacteriologic methods, and other diseases known to cause fibrosis were excluded. The condition of four patients deteriorated rapidly with respiratory failure, and they died with pulmonary fibrosis. Only one patient finally recovered but was left with pulmonary sequelae. Two distinctive morphologic patterns were observed, one in which interstitial fibrosis was predominant and one in which intra-alveolar organization and fibrosis were also present. The alveolar epithelial lining and the basement membranes were disrupted in all patients, as evidenced by ultrastructural observations and by immunofluorescent studies showing gaps in the distribution of type 4 collagen and laminin. Types 1 and 3 collagen accumulated in areas corresponding to thickened interstitium and intra-alveolar fibrosis. Thus, some patients who survive the acute pneumonia of Legionnaires' disease may develop pulmonary fibrosis, and this process may lead to functional impairment or death despite prompt and appropriate treatment.

    2003-01-01

    Full Text Available The objective of this research was to determine the dynamics of change of neuron-specific enolase concentration in patients with acute ischemic brain disease in cerebrospinal fluid and plasma. The study included 103 patients, their mean age 58-66 years. The control group consisted of 16 patients, of matching age and sex, with radicular lesions of discal origin, subjected to diagnostic radiculography. Concentration of neuron-specific enolase was measured by a flouroimmunometric method. The results showed that the concentration of neuron-specific enolase in cerebrospinal fluid and plasma of patients with brain ischemic disease within first seven days significantly increased compared to the control. The highest increase of concentration was established in brain infarction, somewhat lower in reversible ischemic attack, and the lowest in transient ischemic attack. Maximal concentration was established on the 3rd-4th day upon the brain infarction. Neuron-specific enolase concentration in cerebrospinal fluid and plasma may be an indicator of pathophysiological processes in the acute phase of brain ischemia and is significant in early diagnostics and therapy of the disease.

    Oxidative stress plays a major role in the pathogenesis of a variety of acute and chronic diseases. Measurement of the oxidative stress-related end products may be performed, e.g. that of structural isomers of the physiological para-tyrosine, namely meta- and ortho-tyrosine, that are oxidized derivatives of phenylalanine. Recent data suggest that in sepsis, serum level of meta-tyrosine increases, which peaks on the 2(nd) and 3(rd) days (pglucose product in non-diabetic septic cases (pRats were fed a standard high cholesterol-diet, and were given para-tyrosine or vehicle orally. High-cholesterol feeding lead to a significant increase in aortic wall meta-tyrosine content and a decreased vasorelaxation of the aorta to insulin and the glucagon-like peptide-1 analogue, liraglutide, that both could be prevented by administration of para-tyrosine. Concluding, these data suggest that meta- and ortho-tyrosine are potential markers of oxidative stress in acute diseases related to oxidative stress, and may also interfere with insulin action in septic humans. Competition of meta- and ortho-tyrosine by supplementation of para-tyrosine may exert a protective role in oxidative stress-related diseases. PMID:26785996

    2009-11-01

    Full Text Available Abstract Background Matrix metalloproteinases (MMPs constitute a family of zinc-dependent proteases (endopeptidases whose catalytic action is the degradation of the extracellular matrix components. In addition, they play the major role in the degradation of collagen and in the process of tissue remodeling. The present clinical study investigated blood serum levels of metalloproteinases- 1, -2, -3 and -9 in patients with acute and chronic aortic dissection, thoracic aortic aneurysm and acute myocardial ischemia compared to healthy individuals. Methods The blood serum levels of MMP-1, -2, -3 and -9 were calculated in 31 patients with acute aortic dissection, 18 patients with chronic aortic dissection, 18 patients with aortic aneurysm and in 13 patients with acute myocardial ischemia, as well as in 15 healthy individuals who served as the control group. Serum MMP levels were measured by using an ELISA technique. Results There were significantly higher levels of MMP-3 in patients with acute myocardial ischemia as compared to acute aortic dissection (17.33 ± 2.03 ng/ml versus 12.92 ± 1.01 ng/ml, p Conclusion Measurement of serum MMP levels in thoracic aortic disease and acute myocardial ischemia is a simple and relatively rapid laboratory test that could be used as a biochemical indicator of aortic disease or acute myocardial ischemia, when evaluated in combination with imaging techniques.

  19. Acute exudative polymorphous vitelliform maculopathy in a patient with Lyme disease.

    Singh, Ravi S J; Tran, Lac H; Kim, Judy E

    2013-01-01

    Acute exudative polymorphous vitelli-form maculopathy (AEPVM) is a rare condition of unclear etiology that has been seen in association with respiratory and viral infections. It has also been reported as a paraneoplastic phenomenon in older individuals. The authors report the first case of AEPVM associated with Lyme disease with over 3.5 years of follow-up. Multimodality serial imaging suggested the lesions began as multiple serous detachments followed by accumulation of photoreceptor outer segments in the subretinal space that gradually resolved over time and gave rise to the characteristic fundus findings at various stages.

  20. Role of free radicals in the pathogenesis of acute chest syndrome in sickle cell disease

    Farber Harrison W

    2001-07-01

    Full Text Available Abstract Acute chest syndrome (ACS of sickle cell disease (SCD is characterized pathologically by vaso-occlusive processes that result from abnormal interactions between sickle red blood cells (RBCs, white blood cells (WBCs and/or platelets, and the vascular endothelium. One potential mechanism of vascular damage in ACS is by generation of oxygen-related molecules, such as superoxide (O2-, hydrogen peroxide (H2O2, peroxynitrite (ONOO-, and the hydroxyl (•OH radical. The present review summarizes the evidence for alterations in oxidant stress during ACS of SCD, and the potential contributions of RBCs, WBCs and the vascular endothelium to this process.

  1. Development of a positive psychology intervention for patients with acute cardiovascular disease

    Julia K. Boehm

    2011-09-01

    Full Text Available The management of depression and other negative psychological states in cardiac patients has been a focus of multiple treatment trials, though such trials have not led to substantial improvements in cardiac outcomes. In contrast, there has been minimal focus on interventions to increase positive psychological states in cardiac patients, despite the fact that optimism and other positive states have been associated with superior cardiovascular outcomes. Our objective was to develop an 8-week, phone-based positive psychology intervention for patients hospitalized with acute cardiac disease (acute coronary syndrome or decompensated heart failure. Such an intervention would consist of positive psychology exercises adapted for this specific population, and it would need to be feasible for practitioners and patients in real-world settings. By adapting exercises that were previously validated in healthy individuals, we were able to generate a positive psychology telemedicine intervention for cardiac patients that focused on optimism, kindness, and gratitude. In addition, we successfully created a companion treatment manual for subjects to enhance the educational aspects of the intervention and facilitate completion of exercises. Finally, we successfully performed a small pilot trial of this intervention, and found that the positive psychology intervention appeared to be feasible and well-accepted in a cohort of patients with acute cardiac illness. Future studies should further develop this promising intervention and examine its impact on psychological and medical outcomes in this vulnerable population of cardiac patients.

    The presence of an erythematous skin rash and hemorrhagic complications in acute graft-versus-host disease (GVHD) suggest that the vasculature may be involved in the immunopathologic process. We reviewed endothelial and vascular histopathologic changes on light microscopy and on immunoperoxidase stained sections of skin biopsies obtained from 41 HLA-identical allogeneic marrow transplant recipients with at least grade 2 GVHD. Biopsies taken from 14 allogeneic HLA-identical bone marrow transplant recipients who never developed GVHD were used as controls. Sections were evaluated for evidence of immunologic vascular injury using the rank file analysis of histologic features, expression of HLA-DR antigen, and the distribution of fibrin and factor VIII-related antigen (F VIII RAg). Patients with acute GVHD had significantly greater intimal lymphocytic infiltrates, perivascular nuclear dust deposition, perivascular F VIII Rag extravasation and deposition and vascular proliferation than controls. We find significantly greater endothelial injury in GVHD patients, which may represent primary immunologic injury to the vasculature. The clinical findings in acute GVHD probably result from cumulative endothelial as well as epithelial injury. Images Figure 1 Figure 2 Figure 3 PMID:2596572

    In Wilson disease (WD), functional loss of ATPase copper-transporting β (ATP7B) impairs biliary copper excretion, leading to excessive copper accumulation in the liver and fulminant hepatitis. Current US Food and Drug Administration- and European Medicines Agency-approved pharmacological treatments usually fail to restore copper homeostasis in patients with WD who have progressed to acute liver failure, leaving liver transplantation as the only viable treatment option. Here, we investigated the therapeutic utility of methanobactin (MB), a peptide produced by Methylosinus trichosporium OB3b, which has an exceptionally high affinity for copper. We demonstrated that ATP7B-deficient rats recapitulate WD-associated phenotypes, including hepatic copper accumulation, liver damage, and mitochondrial impairment. Short-term treatment of these rats with MB efficiently reversed mitochondrial impairment and liver damage in the acute stages of liver copper accumulation compared with that seen in untreated ATP7B-deficient rats. This beneficial effect was associated with depletion of copper from hepatocyte mitochondria. Moreover, MB treatment prevented hepatocyte death, subsequent liver failure, and death in the rodent model. These results suggest that MB has potential as a therapeutic agent for the treatment of acute WD. PMID:27322060

  4. Mitochondrion-Permeable Antioxidants to Treat ROS-Burst-Mediated Acute Diseases.

    Zhang, Zhong-Wei; Xu, Xiao-Chao; Liu, Ting; Yuan, Shu

    2016-01-01

    Reactive oxygen species (ROS) play a crucial role in the inflammatory response and cytokine outbreak, such as during virus infections, diabetes, cancer, cardiovascular diseases, and neurodegenerative diseases. Therefore, antioxidant is an important medicine to ROS-related diseases. For example, ascorbic acid (vitamin C, VC) was suggested as the candidate antioxidant to treat multiple diseases. However, long-term use of high-dose VC causes many side effects. In this review, we compare and analyze all kinds of mitochondrion-permeable antioxidants, including edaravone, idebenone, α-Lipoic acid, carotenoids, vitamin E, and coenzyme Q10, and mitochondria-targeted antioxidants MitoQ and SkQ and propose astaxanthin (a special carotenoid) to be the best antioxidant for ROS-burst-mediated acute diseases, like avian influenza infection and ischemia-reperfusion. Nevertheless, astaxanthins are so unstable that most of them are inactivated after oral administration. Therefore, astaxanthin injection is suggested hypothetically. The drawbacks of the antioxidants are also reviewed, which limit the use of antioxidants as coadjuvants in the treatment of ROS-associated disorders. PMID:26649144

  5. Acute Sickle Hepatic Crisis after Liver Transplantation in a Patient with Hb SC Disease

    J. H. Gillis

    2015-01-01

    Full Text Available Acute sickle hepatic crisis (ASHC has been observed in approximately 10% of patients with sickle cell disease. It occurs predominantly in patients with homozygous (Hb SS sickle cell anemia and to a lesser degree in patients with Hb SC disease, sickle cell trait, and Hb S beta thalassemia. Patients commonly present with jaundice, right upper quadrant pain, nausea, low-grade fever, tender hepatomegaly, and mild to moderate elevations in serum AST, ALT, and bilirubin. We describe the case of a patient with a history of hemoglobin SC disease and cirrhosis caused by hepatitis C presenting approximately 1 year after liver transplantation with an ASHC. The diagnosis was confirmed by liver biopsy. Our patient was treated with RBC exchange transfusions, IV hydration, and analgesia and made a complete recovery. Only a limited number of patients with sickle cell disease have received liver transplants, and, to our knowledge, this is the first case of ASHC after transplantation in a patient with Hb SC disease.

    2016-01-01

    Addison's disease is a rare endocrine disorder that frequently presents with non-specific symptoms, but may deteriorate rapidly into life-threatening Addisonian crisis if left untreated. Diagnosis can be difficult in patients without a suggestive medical history. We describe a case of a 37-year-old man who was admitted with acute kidney injury and hyperkalaemia, resistant to treatment with insulin/dextrose and calcium gluconate. On clinical examination, he was found to be hyperpigmented; a subsequent random serum cortisol of 49 nmol/L affirmed the preliminary diagnosis of Addison's disease. The patient's hyperkalaemia improved on treatment with hydrocortisone, and a follow-up morning adrenocorticotropic hormone of 1051 ng/L confirmed the diagnosis. PMID:27170604

    2015-01-01

    Full Text Available The mammalian intestinal microbiota is a complex ecosystem that plays an important role in host immune responses. Recent studies have demonstrated that alterations in intestinal microbiota composition are linked to multiple inflammatory diseases in humans, including acute graft-versus-host disease (aGVHD. aGVHD is one of the major obstacles in allogeneic hematopoietic stem cell transplantation (allo-HSCT, characterized by tissue damage in the gastrointestinal (GI tract, liver, lung, and skin. Here, we review the current understanding of the role of intestinal microbiota in the control of immune responses during aGVHD. Additionally, the possibility of using probiotic strains for potential treatment or prevention of aGVHD will be discussed.

  9. Acute Chest Syndrome in Sickle Cell Disease Patients Post Caesarean Delivery

    YM Zhang

    2016-02-01

    Full Text Available Sickle cell disease (SCD is the most common inherited disease worldwide and is associated with anaemia and intermittent painful crisis. Pregnant women who are affected are known to have increased maternal and fetal mortality and morbidity. Acute chest syndrome (ACS is an uncommon but serious complication in pregnant women with SCD that can lead to death. We present two cases of patients with SCD, both of whom had severe ACS within 24 hours post Caesarean section. By accurate diagnosis and appropriate management by a multidisciplinary team, both mothers and fetuses had excellent outcomes. It is suggested that prompt recognition of ACS in a pregnant woman with SCD and collaborative medical and obstetric management are essential to optimize maternal and fetal outcomes.

  11. Seven-year national survey of Kawasaki disease and acute rheumatic fever.

    Taubert, K A; Rowley, A H; Shulman, S T

    1994-08-01

    To assess the frequency of hospital encoded diagnoses of acute rheumatic fever (ARF) and Kawasaki disease (KD), the two leading causes of acquired heart disease in children in the United States, we performed a survey of the medical record departments of United States children's hospitals and of general hospitals that have at least 400 beds and a pediatric ward. With a simple questionnaire, data were gathered for the years 1984 through 1990 by ICD.9CM codes, with a 58% response rate. About 8000 diagnoses of KD and 6000 diagnoses of ARF were encoded during the study period. Encoded diagnoses of both KD and ARF showed yearly fluctuations in the earlier years (1984 through 1987). For KD there was a general trend toward increasing numbers after 1986. These data are consistent with increased physician awareness and diagnosis of KD. For ARF a gradual decline was observed between 1986 and 1990. About 80% of ARF diagnoses were reported from general hospitals. The much smaller pool of encoded diagnoses of ARF at the children's hospitals showed a 56% increase from 1985 to 1986. These data suggest that the highly publicized increase in cases of acute rheumatic fever in the United States during the mid-1980s may reflect focal rather than nationwide increased activity and that nationally the number of diagnoses of ARF actually may have continued to decline gradually from 1984 through 1990.

  12. Relationship between oxygen free radicals, cytokines, cortisol and stress complications in patients with acute cerebrovascular disease

    Objective: To investigate the relationship between oxygen free radicals, cytokines, cortisol and stress complications in patients with acute cerebrovascular disease (ACVD). Methods: Serum levels of superoxide dismutases (SOD), malonaldehyde (MDA) (with biochemistry) interleukin-6 (IL-6), tumor necrosis factor (TNF-α) and cortisol (with RIA) were measured in 32 patients with acute cerebrovascular disease (ACVD) plus stress complications and 48 patients without stress complications as well as 36 controls. Results: Serum SOD contents in non-stressed group were higher than those in stressed group (P<0.05) but lower than those of the controls (P<0.05). However the levels of MDA, IL-6, TNF-α and cortisol were highest in the stressed group and lowest in the controls (all P<0.05). Conclusion: Oxygen free radicals, IL-6, TNF-α and cortisol were involved in stress complications in patients with ACVD. Monitoring the levels of serum SOD, MDA, IL-6, TNF-α and cortisol could be useful for predicting stress complications and evaluating the therapeutic effect. (authors)

    A flock of approximately 1,000 sheep were exposed intermittently to food contaminated with T-2 toxin (T-2), a potent type-A trichothecene mycotoxin produced primarily by Fusarium sporotrichioides and Fusarium poae. In the acute stage of the intoxication, affected sheep developed anorexia, decreased water consumption, ruminal atony, soft faeces and apathy. One hundred and ninety of the exposed sheep died. The main gross lesions observed in animals dying during the acute disease were rumenitis and ulcerative abomasitis, depletion of lymphocytes in lymphoid organs, necrosis of the exocrine pancreas, myocarditis and intense oedema of the skin and brain. Sheep developing the chronic stage of disease showed weight loss and reproductive inefficiency and the main pathological features observed in animals dying during this stage were gastrointestinal inflammation, myocardial fibrosis and necrotic and suppurative lesions in the oral cavity. Opportunistic infections (e.g. mycotic mastitis or parasitic pneumonia) were also identified in these animals. Increased serum concentrations of lactate dehydrogenase and creatine kinase were observed, most likely related to heart lesions. T-2 toxins were detected in all samples of the diet of these animals that were analyzed. The changes in the sheep reported here are similar to those described previously in experimental studies. Lesions observed in the present animals suggest an additional cardiotoxic effect of T-2 in sheep. PMID:22819015

    1993-01-01

    Full Text Available Phospholipase A2 (PLA2 modifications were investigated in patients with acute and chronic liver diseases, PLA2 variations were related to indices of liver function as well as to parameters of the acute phase response. Serum PLA2 activity modifications were f1uorimetrically measured in 105 patients affected by acute and chronic liver diseases or extra-hepatic diseases. One-way ANOV A demonstrated a significant difference among groups (F= 4.53, P<0.001; Bonferroni’s test for pairwise comparisons showed that patients with hepatocellular carcinoma had higher mean values than subjects with benign extra-hepatic diseases (p<0.0 I and mild chronic liver disease (p<0.0S J. Multiple regression analysis, performed choosing PLA2 as the dependent variable and blood urea nitrogen, C-reacti ve protein, alkaline phosphatase and al-fetoprotein as predictor variables was significant (multiple R= 0.7056, multiple R2= 0.4978, F= 15.36, P= <0.0001. The standardized regression coefficients found to be significant were those of Creactive protein, blood urea nitrogen and al-fetoprotein. In conclusion, in patients with chronic liver disease, serum PLA2 activity increases parallel to disease severity and accompanies the expression of proteins of the acute phase response that. like PLA2 activity, increase in serum while liver synthesis declines.

    2016-01-01

    Although many cases of follicular mucinosis are idiopathic, numerous others are associated with mycosis fungoides or, rarely, other neoplastic or inflammatory disorders. There are only three reported cases, all in adults, of follicular mucinosis arising in association with acute myelogenous leukemia, two of which involved mycosis fungoides-associated follicular mucinosis, including one case in which the patient had a preceding bone marrow transplant. We present the first reported case of follicular mucinosis arising in an adolescent with acute myelogenous leukemia and acute graft-versus-host disease after an allogeneic bone marrow transplantation.

    Coronary artery disease is one of the most rampant non-communicable diseases in the world. It begins indolently as a fatty streak in the lining of the artery that soon progresses to narrow the coronary arteries and impair myocardial perfusion. Often the atherosclerotic plaque ruptures and causes sudden thrombotic occlusion and acute ST-elevation myocardial infarction (STEMI), non-ST-elevation MI (NSTEMI) or unstable angina (UA). This phenomenon is called acute coronary syndrome (ACS) and is the leading cause of death not only in Malaysia but also globally. In order for us to tackle this threat to the health of our nation we must arm ourselves with reliable and accurate information to assess current burden of disease resources available and success of current strategies. The acute coronary syndrome (ACS) registry is the flagship of the National Cardiovascular Disease Database (NCVD) and is the result of the dedicated and untiring efforts of doctors and nurses in both public and private medical institutions and hospitals around the country, ably guided and supported by the National Heart Association, the National Heart Foundation, the Clinical Research Centre and the Ministry of Health of Malaysia. Analyses of data collected throughout 2006 from 3422 patients with ACS admitted to the 12 tertiary cardiac centres and general hospitals spanning nine states in Malaysia in this first report has already revealed surprising results. Mean age of patients was 59 years while the most consistent risk factor for STEMI was active smoking. Utilization of medications was high generally. Thirty-day mortality for STEMI was 11%, for NSTEMI 8% and UA 4%. Thrombolysis (for STEMI only) reduced in-hospital and 30-day mortality by nearly 50%. Percutaneous coronary intervention or PCI also reduced 30-day mortality for patients with non-ST elevation MI and unstable angina. The strongest determinants of mortality appears to be Killip Class and age of the patient. Fewer women received

    Abd-Hay I. Abd-Hay; Ahmed S. Alsaily* and Essam A. El-Moselhy

    2011-04-01

    Full Text Available Introduction: Acute exacerbation of chronic obstructive pulmonary disease (COPD is a frequent cause of hospitalization and intensive care unit admission. Respiratory failure from airflow obstruction is a direct consequence of acute airway narrowing. Aim of the study: It was to compare the efficacy of noninvasive mechanical ventilation (NIMV against conventional mechanical ventilation (CMV in patients with acute exacerbation of COPD. Patients and methods: Forty patients with acute exacerbation of COPD were recruited in the present study. A comparative, hospital based study design was used. All the cases were examined; clinically and laboratory. The patients were divided into two groups each include 20 patients. Group A received NIMV in the form of continuous positive airway pressure (CPAP and group B with CMV. Results: There were statistically significant decreases in respiratory rate, heart rate and diastolic blood pressure after 6 hours of CPAP in comparison to baseline parameters in group A. While, there were statistically significant increases in PaO2 and SaO2 after 6 hours of CPAP in comparison to baseline parameters. In group B there were statistically significant decreases in respiratory rate, heart rate, systolic blood pressure and diastolic blood pressure after 6 hours of CMV in comparison to baseline parameters. While, there were statistically significant increases in pH, PaO2, and SaO2 and a statistically significant decrease in PaCO2 after 6 hours of CMV in comparison to baseline parameters. Further, comparison of respiratory rate and hemodynamic parameters in both groups showed statistically significant decreases in respiratory rate, heart rate, systolic blood pressure and diastolic blood pressure in group A in comparison to group B. Finally, failure rate was 35.0% in group A (NIMV compared to 5.0% in group B (CMV with statistically significant difference. Conclusions and recommendations: Noninvasive mechanical ventilation is a safe

    Gaucher disease arises from mutations in the β-glucocerebrosidase gene which encodes an enzyme required for the lysosomal catabolism of glucosylceramide. We have identified a naturally occurring mutation in the β-glucocerebrosidase gene in sheep that leads to Gaucher disease with acute neurological symptoms. Here we have examined the clinical phenotype at birth and subsequently quantified lipids in Gaucher lamb brain, in order to characterise the disorder. Enzyme activity assessments showed that a reduction in β-glucocerebrosidase activity to 1-5% of wild-type occurs consistently across newborn Gaucher lamb brain regions. We analyzed glucosylceramide, glucosylsphingosine, bis(monoacylglycero)phosphate and ganglioside profiles in brain, liver, and spleen, and observed 30- to 130-fold higher glucosylceramide, and 500- to 2000-fold higher glucosylsphingosine concentrations in Gaucher diseased lambs compared to wild-type. Significant increases of bis(monoacylglycero)phosphate and gangliosides [GM1, GM2, GM3] concentrations were also detected in the brain. As these glycosphingolipids are involved in many cellular events, an imbalance or disruption of the cell membrane lipid homeostasis would be expected to impair normal neuronal function. To our knowledge, this is the first detailed analysis of glycosphingolipids in various brain regions in a large animal model of neuronal disease, which permits the mechanistic investigation of lipid deregulation and their contribution to neurodegenerative process.

    Distemper disease is an infectious disease reported in several species of domestic and wild carnivores. The high mortality rate of animals infected with canine distemper virus (CDV) treated with currently available therapies has driven the study of new efficacious treatments. Mesenchymal stem cell (MSC)-based therapy is a promising therapeutic option for many degenerative, hereditary, and inflammatory diseases. Therefore, the aim of this study was to characterize stem cells derived from the canine fetal olfactory epithelium and to assess the systemic response of animals infected with CDV to symptomatic therapy and treatment with MSCs. Eight domestic mongrel dogs (N = 8) were divided into two groups: support group (SG) (N = 5) and support group + cell therapy (SGCT) (N = 3), which were monitored over 15 days. Blood samples were collected on days 0, 6, 9, 12, and 15 to assess blood count and serum biochemistry (urea, creatinine, alanine transferase, alkaline phosphatase, gamma-glutamyl transferase, total protein, albumin, and globulin), and urine samples were obtained on days 0 and 15 for urinary evaluation (urine I). The results showed a high mortality rate (SG = 4 and SGCT = 2), providing inadequate data on the clinical course of CDV infection. MSC therapy resulted in no significant improvement when administered during the acute phase of canine distemper disease, and a prevalence of animals with high mortality rate was found in both groups due to the severity of symptoms.

    Full Text Available Background: Intestinal anastomosis in severely ill children with peritonitis from intestinal perforation, intestinal gangrene or anastomotic dehiscence (acute intestinal disease is associated with high morbidity and mortality. Enterostomy as a damage control measure may be an option to minimize the high morbidity and mortality. This report evaluates the role of damage control enterostomy in the treatment of these patients. Materials and Methods: A retrospective review of 52 children with acute intestinal disease who had enterostomy as a damage control measure in 12 years. Results: There were 34 (65.4% boys and 18 (34.6% girls aged 3 days-13 years (median 9 months, comprising 27 (51.9% neonates and infants and 25 (48.1% older children. The primary indication for enterostomy in neonates and infants was intestinal gangrene 25 (92.6% and perforated typhoid ileitis 22 (88% in older children. Enterostomy was performed as the initial surgery in 33 (63.5% patients and as a salvage procedure following anastomotic dehiscence in 19 (36.5% patients. Enterostomy-related complications occurred in 19 (36.5% patients, including 11 (21.2% patients with skin excoriations and eight (15.4% with hypokalaemia. There were four (7.7% deaths (aged 19 days, 3 months, 3½ years and 10 years, respectively directly related to the enterostomy, from hypokalaemia at 4, 12, 20 and 28 days postoperatively, respectively. Twenty other patients died shortly after surgery from their primary disease. Twenty of 28 surviving patients have had their enterostomy closed without complications, while eight are awaiting enterostomy closure. Conclusion: Damage-control enterostomy is useful in management of severely ill children with intestinal perforation or gangrene. Careful and meticulous attention to fluid and electrolyte balance, and stoma care, especially in the first several days following surgery, are important in preventing morbidity and mortality.

    Full Text Available Abstract Background Small intestinal bacterial overgrowth (SIBO is characterized by excessive proliferation of colonic bacterial species in the small bowel. Potential causes of SIBO include fistulae, strictures or motility disturbances. Hence, patients with Crohn's Disease (CD are especially predisposed to develop SIBO. As result, CD patients may experience malabsorption and report symptoms such as weight loss, watery diarrhea, meteorism, flatulence and abdominal pain, mimicking acute flare in these patients. Methods One-hundred-fifty patients with CD reporting increased stool frequency, meteorism and/or abdominal pain were prospectively evaluated for SIBO with the Hydrogen Glucose Breath Test (HGBT. Results Thirty-eight patients (25.3% were diagnosed with SIBO based on positive findings at HGBT. SIBO patients reported a higher rate of abdominal complaints and exhibited increased stool frequency (5.9 vs. 3.7 bowel movements/day, p = 0.003 and lower body weight (63.6 vs 70.4 kg, p = 0.014. There was no correlation with the Crohn's Disease Activity Index. SIBO was significantly more frequent in patients with partial resection of the colon or multiple intestinal surgeries; there was also a clear trend in patients with ileocecal resection that did not reach statistical significance. SIBO rate was also higher in patients with affection of both the colon and small bowel, while inflammation of the (neoterminal ileum again showed only tendential association with the development of SIBO. Conclusion SIBO represents a frequently ignored yet clinically relevant complication in CD, often mimicking acute flare. Because symptoms of SIBO are often difficult to differentiate from those caused by the underlying disease, targeted work-up is recommended in patients with corresponding clinical signs and predisposing factors.

  4. Cyclosporin-Methotrexate Compared with Cyclosporin-Methotrexate-Methylprednisolone Therapy for the Prophylaxis of Acute Graft-Versus Host Disease

    Acute graft-versus host (GVHD) disease is a common immunologic complication, which occurs in 40-50% of the recipients of allogenic stem cell transplantation (SCT). The role of corticosteroid in the prevention of GVHD is not well established. We report here a study to determine whether the addition of methylprednisolone to the combination of cyclosporine (CSA) and methotrexate (MTX), methylp-rednisolone (MP) for the prophylaxis of acute GVHD would further decrease the incidence of acute GVHD. A group of patients (25 patients with acute myeloid leukemia (AML) and 12 patients with acute lymphocytic leukemia (ALL) that received CSA/MTX/MP started from 2004 to 2008, were compared to a historical group of patients (19 patient with acute myeloid leukemia (AML) and 12 patients with acute lymphocytic leukemia (ALL) that received GVHD prophylaxis in the form of CSA/MTX only from 1999 to 2003). The primary endpoint in this study was the develop-ment of GVHD and the secondary end point was overall and disease free survival. Both groups of patients were matched for age, sex, donor recipient sex, low risk patients and high risk patients. Although the incidence of acute GVHD in the MP -ve group was 35% versus 24% in the MP+ve group, there was no significant difference between them. The overall survival showed a significant difference between the 2 groups (p<0.05). It was 48% for the 2 drug regimen (CSA/MTX) vs. 81% for the three drug regimen (CSA/MTX/MP). There was a significant decrease in the relapse rate in patients on CSA/MTX/MP (p<0.05). In conclusion, the addition of MP (methylprednis-olone) to the combination of CSA/MTX did not affect the incidence of acute GVHD significantly in allogeneic SCT but surprisingly the incidence of survival and relapse was markedly increased and decreased respectively

  5. Risk factors for acute Toxoplasma gondii diseases in Taiwan: a population-based case-control study.

    Ting-Yi Chiang

    Full Text Available Although human toxoplasmosis is a notifiable disease in Taiwan since 2007, little is known about its risk factors. This study aimed to investigate the risk factors for acute Toxoplasma gondii diseases in Taiwan. We conducted a nationwide population-based case-control study. Cases of acute human toxoplasmosis notified to the Taiwan Centers for Diseases Control (Taipei, Taiwan during 2008-2013 were compared with controls that were randomly selected from healthy T. gondii-seronegative blood donors who participated in a nationwide T. gondii seroepidemiologic study during 2009-2010. Cases and controls were matched according to age, gender and residency at an 1:8 ratio. Structured questionnaires were used to gather information regarding risk factors. A total of 30 laboratory-confirmed acute T. gondii disease cases and 224 controls were enrolled. The most common clinical manifestation of the cases was flu-like symptoms (n = 20, followed by central nervous system disease (n = 4, ocular diseases (n = 3, abortion (n = 2, and congenital infection (n = 1. Multivariate conditional logistic regression showed that raw clam consumption (adjusted odds ratio [OR] = 3.7; 95% confidence interval [CI] = 1.4-9.9 and having a cat in the household (adjusted OR = 2.9; 95% CI = 1.1-7.9 were two independent risk factors for acute T. gondii disease. We conclude that raw shellfish consumption and domestic cat exposure were risk factors for acquiring acute T. gondii diseases in Taiwan. This finding may guide future research and control policies.

    The aim of this work was to evaluate whether acute phase protein (APP) determinations could assist Official Veterinarians carrying out work in slaughterhouses. To test this hypothesis, the diagnostic accuracy of APP determinations in meat juice of pigs was analysed to differentiate between healthy and diseased pigs. One hundred and one pigs of two different origins were classified into two groups according to their health status (healthy and diseased pigs), which was determined by a veterinary clinical examination on the farm. To assess the pigs' immune status, against the main porcine diseases, serological analyses were monitored. A general idea of the degree of disease coverage was analysed by examining organ lesions postmortem. Haptoglobin (Hp) and C reactive protein (CRP) were measured in meat juice samples. 72.13 per cent of pigs appeared to be seropositive for the porcine respiratory and reproductive syndrome virus, and almost 86.2 per cent of them had concomitant infections with other pathogens, such as Porcine circovirus type 2 or Swine influenza virus. Median Hp and CRP concentrations were significantly higher in diseased animals at different stages of the production chain, when compared with levels found in healthy finishing pigs (P<0.0001). Receiver operating characteristic analysis showed the highest sensitivity-specificity pairs, nearly 80-90 per cent, at cut-off levels of 83 and 10 µg/ml for Hp and CRP determinations, respectively, with high AUCs 0.9. This cut-off could be useful for veterinary inspections at the time of slaughter, to differentiate between the carcase of a healthy animal and the carcase of an animal suffering from a systemic disease, which should be completely condemned.

    Jess, T; Jess, Per

    2001-01-01

    Background: During the past decade, very little has been published on the relationships between Yersinia enterocolitica, acute terminal ileitis (ATI), and Crohn's disease, possibly due to a decrease in Yersinia infections and, consequently, in ATI. Methods: Fifty-three patients admitted to Herlev...... University Hospital during the period 1976-1998 were diagnosed as having ATI while undergoing surgery for suspected acute appendicitis. The patients were followed up, and both Yersinia titers and the development of Crohn's disease were registered. Results: Forty-four patients (83%) were tested for Yersinia...

    2007-12-01

    Full Text Available Allogeneic stem cell transplantation has been increasingly performed for a variety of hematologic diseases. Clinically significant acute graft-versus-host disease (GVHD occurs in 9 to 50% of patients who receive allogeneic grafts, resulting in high morbidity and mortality. There is no standard therapy for patients with acute GVHD who do not respond to steroids. Studies have shown a possible benefit of anti-TNF-a (infliximabfor the treatment of acute GVHD. We report here on the outcomes of 10 recipients of related or unrelated stem cell transplants who received 10 mg/kg infliximab, iv, once weekly for a median of 3.5 doses (range: 1-6 for the treatment of severe acute GVHD and who were not responsive to standard therapy. All patients had acute GVHD grades II to IV (II = 2, III = 3, IV = 5. Overall, 9 patients responded and 1 patient had progressive disease. Among the responders, 3 had complete responses and 6 partial responses. All patients with cutaneous or gastrointestinal involvement responded, while only 2 of 6 patients with liver disease showed any response. None of the 10 patients had any kind of immediate toxicity. Four patients died, all of them with sepsis. Six patients are still alive after a median follow-up time of 544 days (92-600 after transplantation. Considering the severity of the cases and the bad prognosis associated with advanced acute GVHD, we find our results encouraging. Anti-TNF-a seems to be a useful agent for the treatment of acute GVHD.

    Full Text Available The aim of this study was to investigate the correlation between procalcitonin and other acute phase reactants, and also analyze their relationship with clinical situation in chronic obstructive pulmonary disease (COPD acute exacerbations.Materials and methods: The study was made with 122 acute COPD exacerbated patients, who were admitted to emergency service. Patients with below 0.25 ng/ml PCT value included Group 1, and the patients with PCT values ≥ 0.25 ng/ml Group 2. Serum procalcitonin levels, erythrocyte sedimentation rate (ESR, C-reactive protein (CRP values and white blood cell (WBC counts were measured. Also, patients hospitalization time and mortality rates were recorded and compared with PCT.Results: Patients were divided in 3 groups according to their clinical diagnosis; Pneumonia (n=27, Mycoplasma-Chlamydia pneumonia (n=11 and the patients with only COPD exacerbation(n=84. Mean PCT values according to the groups were 9.47 ± 8.1 ng/ml, 0.41 ± 0.2 ng/ml, and 0.21 ± 0.05 ng/ml respectively. The relationship between PCT with CRP and white blood cell has been found between significiant (p=0.001, p=0.005 respectively, whereas the relationship between PCT and ESR was nonsignificant (p=0.55. Procalcitonin and CRP had a positive correlation with the hospitalization time (p=0.034, p=0.022 respectively. The mean ± standard error of PCT for the patients who died was 28.3 ± 27.5 ng/ml, and the difference between patients who died or were discharged was statistically significant (p= 0.012.Conclusion: PCT can be a useful indicator for morbidity and prognosis in COPD patients.

    Coronary artery inflammation and aneurysm formation are the most common complications of Kawasaki disease (KD). Valvulitis and myocarditis are also well described and may lead to valvar regurgitation and left ventricular dysfunction. However, functional changes in the right heart have rarely been reported. We noted several acute KD patients with dilated pulmonary arteries (PA) and thus sought to systematically characterize PA size and right-heart function in an unselected cohort of KD patients cared for at a single clinical center. Clinical, laboratory, and echocardiographic data from 143 acute KD subjects were analyzed. PA dilation was documented in 23 subjects (16.1 %); these subjects had higher median right ventricle myocardial performance index (RV MPI), higher ratio of early tricuspid inflow velocity to tricuspid annular early diastolic velocity (TV E/e'), and lower median TV e' velocity compared to the non-PA dilation group (0.50 vs 0.38 p < 0.01, 4.2 vs 3.6 p < 0.05, and 13.5 vs 15.2 cm/s p < 0.01, respectively). Almost all subjects with PA dilation had improved PA Z-score, RV MPI, and TV E/e' in the subacute phase (p < 0.01). There were no significant differences in indices of left ventricle function between PA dilation group and non-PA dilation group. In summary, PA dilation was documented in 16 % of acute KD subjects. These subjects were more likely to have echocardiographic indices consistent with isolated RV dysfunction that improved in the subacute phase. The long-term consequence of these findings will require longitudinal studies of this patient population. PMID:26681305

    Full Text Available Objective To investigate the use of enteral immune nutrition preparation in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD, regard its efficacy in improving nutritional status, and its influence on immunity and the status of acute inflammatory reaction of the patients. Methods Sixty-two AECOPD patients requiring mechanical ventilation in ICU of our hospital were randomly divided into two groups: immune nutrition group [study group, n=32, receiving Ruineng (a product of Huarui Pharmaceutical Ltd., which contained essential fatty acids, Omega-3 fatty acids, and energy 1.3 kcal/ml] and conventional nutrition group (control group, n=30, receiving the hospital self-made homogenized diet with 1.2 kal/ml. Patients in the two groups took enteral nutrition of equal calorie, and it was given by nasointestinal tube. On the day of admission and the 14th and 18th after admission, venous blood was obtained for the determination of serum albumin, prealbumin, transferrin, C reactive protein (CRP, tumor necrosis factor-α (TNF-α, and interleukin-6 (IL-6. At the same time upper arm muscle circumference (MAMC was measured at the bed side. The 14-day off-respirator rate and mechanical ventilation time within 28 days were compared between the two groups. Results The 14-day off-respirator rate was higher in study group than in control group (P0.05. Conclusions Compared with homogenized diet, immune enteral nutrition could better improve the nutritional status and immune function, lower the acute inflammatory response level, increase the success rate of early off-respirator in AECOPD patients, therefore, enteral immune nutrition preparation is a better nutrition support solution for AECOPD.

    Studies indicate the involvement of brain-derived neurotrophic factor (BDNF) in the pathogenesis of Alzheimer's disease (AD). Decreased BDNF levels may constitute a lack of trophic support and contribute to cognitive impairment in AD. The benefits of acute and chronic physical exercise on BDNF levels are well-documented in humans, however, exercise effects on BDNF levels have not been analyzed in older adults with AD. The aim of this study was to investigate the effects of acute aerobic exercise on BDNF levels in older adults with AD and to verify associations among BDNF levels, aerobic fitness, and level of physical activity. Using a controlled design, twenty-one patients with AD (76.3 ± 6.2 years) and eighteen healthy older adults (74.6 ± 4.7 years) completed an acute aerobic exercise. The outcomes included measures of BDNF plasma levels, aerobic fitness (treadmill grade, time to exhaustion, VO2, and maximal lactate) and level of physical activity (Baecke Questionnaire Modified for the Elderly). The independent t-test shows differences between groups with respect to the BDNF plasma levels at baseline (p = 0.04; t = 4.53; df = 37). In two-way ANOVA, a significant effect of time was found (p = 0.001; F = 13.63; df = 37), the aerobic exercise significantly increased BDNF plasma levels in AD patients and healthy controls. A significant correlation (p = 0.04; r = 0.33) was found between BDNF levels and the level of physical activity. The results of our study suggest that aerobic exercise increases BDNF plasma levels in patients with AD and healthy controls. In addition to that, BDNF levels had association with level of physical activity. PMID:24164734

    Child day-care attendance is considered to be an acute early childhood disease risk factor, the studies available however not affording the possibility of fully quantifying this risk. A systematic review of clinical trials and cohort studies was conducted, in which the effects child day-care attendance had on the health of young children based on the Cochrane Collaboration, PubMed and Spanish Medical Index databases, without any time or language-related limits, were analyzed and rounded out with analyses of referenced works and an additional EMBASE search. The methodological quality was evaluated by means of personalized criteria. Pooling measures (relative risks, incidence density ratios and weighted mean differences) were calculated with their confidence intervals, assuming random effects models. A significant increase was found to exist of a risk consistent over time and among different social and geographical environments. Considering the most methodologically-stringent studies with adjusted effect estimates, child day-care attendance was related to an increased risk of upper respiratory tract infection (RR=1,88), acute otitis media (RR=1,58), otitis media with fluid draining (RR=2,43), lower respiratory tract infections (overall RR=210; acute pneumonia RR=1.70; broncholitis RR=1,80; bronchitis RR=2,10) and gastroenteritis (RR=1,40). Child day-care attendance could be responsible for 33%-50% of the episodes of respiratory infection and gastroenteritis among the exposed population. In conclusion, it can be said that the risk for childhood health attributable to the child day-care attendance is discreet but of high-impact. This information has some major implications for research, clinical practice, healthcare authorities and society as a whole. PMID:17639680

    Full Text Available J Andrew Woods,1 James S Wheeler,1 Christopher K Finch,2 Nathan A Pinner3 1School of Pharmacy, Wingate University, Wingate, NC, USA; 2Department of Pharmacy, Methodist University Hospital, Memphis, TN, USA; 3Harrison School of Pharmacy, Auburn University, Auburn, AL, USA Background: Chronic obstructive pulmonary disease (COPD is a chronic and progressive disease that affects an estimated 10% of the world's population over the age of 40 years. Worldwide, COPD ranks in the top ten for causes of disability and death. Given the significant impact of this disease, it is important to note that acute exacerbations of COPD (AECOPD are by far the most costly and devastating aspect of disease management. Systemic steroids have long been a standard for the treatment of AECOPD; however, the optimal strategy for dosing and administration of these medications continues to be debated. Objective: To review the use of corticosteroids in the treatment of acute exacerbations of COPD. Materials and methods: Literature was identified through PubMed Medline (1950–February 2014 and Embase (1950–February 2014 utilizing the search terms corticosteroids, COPD, chronic bronchitis, emphysema, and exacerbation. All reference citations from identified publications were reviewed for possible inclusion. All identified randomized, placebo-controlled trials, meta-analyses, and systematic reviews evaluating the efficacy of systemic corticosteroids in the treatment of AECOPD were reviewed and summarized. Results: The administration of corticosteroids in the treatment of AECOPD was assessed. In comparison to placebo, systemic corticosteroids improve airflow, decrease the rate of treatment failure and risk of relapse, and may improve symptoms and decrease the length of hospital stay. Therefore, corticosteroids are recommended by all major guidelines in the treatment of AECOPD. Existing literature suggests that low-dose oral corticosteroids are as efficacious as high

    2012-01-01

    Full Text Available We evaluated prevalence and clinical outcome of polyvascular disease (PolyVD in patients presenting with acute coronary syndrome (ACS. Data for 7689 consecutive ACS patients were collected from the 2nd Gulf Registry of Acute Coronary Events between October 2008 and June 2009. Patients were divided into 2 groups (ACS with versus without PolyVD. All-cause mortality was assessed at 1 and 12 months. Patients with PolyVD were older and more likely to have cardiovascular risk factors. On presentation, those patients were more likely to have atypical angina, high resting heart rate, high Killip class, and GRACE risk scoring. They were less likely to receive evidence-based therapies. Diabetes mellitus, renal failure, and hypertension were independent predictors for presence of PolyVD. PolyVD was associated with worse in-hospital outcomes (except for major bleedings and all-cause mortality even after adjusting for baseline covariates. Great efforts should be directed toward primary and secondary preventive measures.

    The clinical staging of acute graft-versus-host disease (GVHD) varies significantly among bone marrow transplant (BMT) centers, but adherence to long-standing practices poses formidable barriers to standardization among centers. We have analyzed the sources of variability and developed a web-based remote data entry system that can be used by multiple centers simultaneously and that standardizes data collection in key areas. This user-friendly, intuitive interface resembles an online shopping site and eliminates error-prone entry of free text with drop-down menus and pop-up detailed guidance available at the point of data entry. Standardized documentation of symptoms and therapeutic response reduces errors in grade assignment and allows creation of confidence levels regarding the diagnosis. Early review and adjudication of borderline cases improves consistency of grading and further enhances consistency among centers. If this system achieves widespread use it may enhance the quality of data in multicenter trials to prevent and treat acute GVHD. PMID:25455279

    Maple syrup urine disease (MSUD) is an inborn error of amino acid metabolism, which affects the brain tissue resulting in impairment or death if untreated. Imaging studies have shown reversible brain edema during acute metabolic decompensation. The purpose of this paper is to describe the diffusion-weighted imaging (DWI) and spectroscopy findings during metabolic decompensation and to assess the value of these findings in the prediction of patient outcome. Six patients with the diagnosis of MSUD underwent conventional MR imaging with DWI during acute presentation with metabolic decompensation. Spectroscopy with long TE was performed in four of the six patients. Follow-up examinations were performed after clinical and metabolic recovery. DWI demonstrated marked restriction of proton diffusion compatible with cytotoxic or intramyelinic sheath edema in the brainstem, basal ganglia, thalami, cerebellar and periventricular white matter and the cerebral cortex. This was accompanied by the presence of an abnormal branched-chain amino acids (BCAA) and branched-chain alpha-keto acids (BCKA) peak at 0.9 ppm as well as elevated lactate on proton spectroscopy in all four patients. The changes in all six patients were reversed with treatment without evidence of volume loss or persistent tissue damage. The presence of cytotoxic or intramyelinic edema as evidenced by restricted water diffusion on DWI, with the presence of lactate on spectroscopy, could imply imminent cell death. However, in the context of metabolic decompensation in MSUD, it appears that changes in cell osmolarity and metabolism can reverse completely after metabolic correction. (orig.)

    Acute kidney injury (AKI) is closely associated with the mortality of hospitalized patients and long-term development of chronic kidney disease, especially in children. The purpose of our study was to assess the evidence of contrast-induced AKI after cardiac catheterization in children with heart disease and evaluate the clinical usefulness of candidate biomarkers in AKI. A total of 26 children undergoing cardiac catheterization due to various heart diseases were selected and urine and blood samples were taken at 0 hr, 6 hr, 24 hr, and 48 hr after cardiac catheterization. Until 48 hr after cardiac catheterization, there was no significant increase in serum creatinine level in all patients. Unlike urine kidney injury molecule-1, IL-18 and neutrophil gelatinase-associated lipocalin, urine liver-type fatty acid-binding protein (L-FABP) level showed biphasic pattern and the significant difference in the levels of urine L-FABP between 24 and 48 hr. We suggest that urine L-FABP can be one of the useful biomarkers to detect subclinical AKI developed by the contrast before cardiac surgery. PMID:25120320

    Acute hepatopancreatic necrosis disease (AHPND) has recently emerged as a serious disease of cultured shrimp. It has also been described as early mortality syndrome (EMS) due to mass mortalities occurring within 20 to 30 d after stocking of ponds with postlarvae. Here, Penaeus vannamei and Penaeus monodon from shrimp farms in the Philippines were examined for the toxin-producing strain of Vibrio parahaemolyticus due to AHPND-like symptoms occurring in marketable size shrimp. In the P. vannamei, histology revealed typical AHPND pathology, such as sloughing of undifferentiated cells in the hepatopancreatic tubule epithelium. Analysis using the IQ2000 AHPND/EMS Toxin 1 PCR test generated 218 bp and 432 bp amplicons confirmative of the toxin-producing strain of V. parahaemolyticus among shrimp sampled from 8 of 9 ponds. In the P. monodon, histology revealed massive sloughing of undifferentiated cells of the hepatopancreatic tubule epithelium in the absence of basophilic bacterial cells. PCR testing generated the 2 amplicons confirmatory for AHPND among shrimp sampled from 5 of 7 ponds. This study confirms the presence of AHPND in P. vannamei and P. monodon farmed in the Philippines and suggests that the disease can also impact late-stage juvenile shrimp. PMID:26503780

  1. Severe metabolic alkalosis and recurrent acute on chronic kidney injury in a patient with Crohn's disease

    2010-04-01

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

    Acute intermittent porphyria (AIP) is a genetic disorder of the synthesis of heme caused by a deficiency in hydroxymethylbilane synthase (HMBS), leading to the overproduction of the porphyrin precursors δ-aminolevulinic acid and porphobilinogen. The aim of this study is to describe the clinical and biological characteristics, the renal pathology, and the cellular mechanisms of chronic kidney disease associated with AIP. A total of 415 patients with HMBS deficiency followed up in the French Porphyria Center were enrolled in 2003 in a population-based study. A follow-up study was conducted in 2013, assessing patients for clinical, biological, and histological parameters. In vitro models were used to determine whether porphyrin precursors promote tubular and endothelial cytotoxicity. Chronic kidney disease occurred in up to 59% of the symptomatic AIP patients, with a decline in the glomerular filtration rate of ~1 ml/min per 1.73 m(2) annually. Proteinuria was absent in the vast majority of the cases. The renal pathology was a chronic tubulointerstitial nephropathy, associated with a fibrous intimal hyperplasia and focal cortical atrophy. Our experimental data provide evidence that porphyrin precursors promote endoplasmic reticulum stress, apoptosis, and epithelial phenotypic changes in proximal tubular cells. In conclusion, the diagnosis of chronic kidney disease associated with AIP should be considered in cases of chronic tubulointerstitial nephropathy and/or focal cortical atrophy with severe proliferative arteriosclerosis.

  3. Endothelial Fas-Ligand in Inflammatory Bowel Diseases and in Acute Appendicitis.

    Kokkonen, Tuomo S; Karttunen, Tuomo J

    2015-12-01

    Fas-mediated induction of apoptosis is a major factor in the selection of lymphocytes and downregulation of immunological processes. In the present study, we have assessed endothelial Fas-ligand (FasL) expression in normal human ileum, appendix, and colon, and compared the expression levels with that in inflammatory bowel disease and in acute appendicitis. In a normal appendix, endothelial FasL levels were constant in almost half of the mucosal vessels; but, in the normal ileum and colon, endothelial FasL was practically restricted to areas in close proximity to lymphatic follicles, and was expressed mainly in the submucosal aspect of the follicles in the vessels with high endothelium. In samples from subjects with either Crohn's disease or ulcerative colitis, the extent of endothelial FasL expression was elevated in the submucosa and associated with an elevated number of lymphoid follicles. In inflammatory bowel disease, ulcers and areas with a high density of mononuclear cells expressing FasL also showed an elevated density of blood vessels with endothelial FasL expression. Although the function of endothelial FasL remains unclear, such a specific expression pattern suggests that endothelial FasL expression has a role in the regulation of lymphocyte access to the peripheral lymphoid tissues, including the intestinal mucosa.

  4. Chronic inflammatory systemic diseases: An evolutionary trade-off between acutely beneficial but chronically harmful programs.

    Straub, Rainer H; Schradin, Carsten

    2016-01-01

    It has been recognized that during chronic inflammatory systemic diseases (CIDs) maladaptations of the immune, nervous, endocrine and reproductive system occur. Maladaptation leads to disease sequelae in CIDs. The ultimate reason of disease sequelae in CIDs remained unclear because clinicians do not consider bodily energy trade-offs and evolutionary medicine. We review the evolution of physiological supersystems, fitness consequences of genes involved in CIDs during different life-history stages, environmental factors of CIDs, energy trade-offs during inflammatory episodes and the non-specificity of CIDs. Incorporating bodily energy regulation into evolutionary medicine builds a framework to better understand pathophysiology of CIDs by considering that genes and networks used are positively selected if they serve acute, highly energy-consuming inflammation. It is predicted that genes that protect energy stores are positively selected (as immune memory). This could explain why energy-demanding inflammatory episodes like infectious diseases must be terminated within 3-8 weeks to be adaptive, and otherwise become maladaptive. Considering energy regulation as an evolved adaptive trait explains why many known sequelae of different CIDs must be uniform. These are, e.g. sickness behavior/fatigue/depressive symptoms, sleep disturbance, anorexia, malnutrition, muscle wasting-cachexia, cachectic obesity, insulin resistance with hyperinsulinemia, dyslipidemia, alterations of steroid hormone axes, disturbances of the hypothalamic-pituitary-gonadal (HPG) axis, hypertension, bone loss and hypercoagulability. Considering evolved energy trade-offs helps us to understand how an energy imbalance can lead to the disease sequelae of CIDs. In the future, clinicians must translate this knowledge into early diagnosis and symptomatic treatment in CIDs. PMID:26817483

    2008-10-01

    5-arylethenylbenzofuroxan derivatives with high in vitro anti-Trypanosoma cruzi activity were studied in vivo using acute murine models of Chagas' disease. The selected compounds, as pure isomeric forms, 1, 2, 3 and 4, or as equimolecular mixture of geometric isomers, 1:2, 3:4, 5:6 were studied against different T. cruzi strains. Consequently, Tulahuen 2 strain, Colombiana strain (resistant to Nifurtimox and Benznidazole), and two different wild strains, one isolated from the wild reservoir Didelphis marsupialis and another one from Uruguayan patients, were selected. No relevant signs of in vivo toxicity were observed with the benzofuroxans orally administered. Compound 1 and the mixture of isomers 1:2 were the best for treating infection against the four studied strains. PMID:18255195

  7. [Serological studies of the role of the respiratory syncytial virus in acute respiratory diseases in children].

    Vancea, D; Saşcă, C; Matinca, D; Ivanof, A

    1975-01-01

    The presence of the syncytial respiratory virus was determined by CF in 281 children admitted with acute respiratory diseases between 15 Sept. 1971 and 30 Dec. 1973, using the Long antigen prepared in the "St. Nicolau" Institute of Virology, Bucharest. In 38 children (13.5%) a serologic diagnosis of infection with the syncytial virus was established; in the other cases of respiratory infection of different etiology, antibodies to the syncytial virus were found in low but constant titers in both serum samples. The presence of these antibodies in a high proportion of the children points to the wide circulation of the syncytial virus in the infantile population, with all its clinico-epidemiologic implications.

  9. Immune Responses in Acute and Convalescent Patients with Mild, Moderate and Severe Disease during the 2009 Influenza Pandemic in Norway.

    Kristin G-I Mohn

    Full Text Available Increased understanding of immune responses influencing clinical severity during pandemic influenza infection is important for improved treatment and vaccine development. In this study we recruited 46 adult patients during the 2009 influenza pandemic and characterized humoral and cellular immune responses. Those included were either acute hospitalized or convalescent patients with different disease severities (mild, moderate or severe. In general, protective antibody responses increased with enhanced disease severity. In the acute patients, we found higher levels of TNF-α single-producing CD4+T-cells in the severely ill as compared to patients with moderate disease. Stimulation of peripheral blood mononuclear cells (PBMC from a subset of acute patients with peptide T-cell epitopes showed significantly lower frequencies of influenza specific CD8+ compared with CD4+ IFN-γ T-cells in acute patients. Both T-cell subsets were predominantly directed against the envelope antigens (HA and NA. However, in the convalescent patients we found high levels of both CD4+ and CD8+ T-cells directed against conserved core antigens (NP, PA, PB, and M. The results indicate that the antigen targets recognized by the T-cell subsets may vary according to the phase of infection. The apparent low levels of cross-reactive CD8+ T-cells recognizing internal antigens in acute hospitalized patients suggest an important role for this T-cell subset in protective immunity against influenza.

  10. Incorporating measurable ('minimal') residual disease-directed treatment strategies to optimize outcomes in adults with acute myeloid leukemia.

    Pettit, Kristen; Stock, Wendy; Walter, Roland B

    2016-07-01

    Curative-intent therapy leads to complete remissions in many adults with acute myeloid leukemia (AML), but relapse remains common. Numerous studies have unequivocally demonstrated that the persistence of measurable ('minimal') residual disease (MRD) at the submicroscopic level during morphologic remission identifies patients at high risk of disease recurrence and short survival. This association has provided the impetus to customize anti-leukemia therapy based on MRD data, a strategy that is now routinely pursued in acute promyelocytic leukemia (APL). While it is currently uncertain whether this approach will improve outcomes in AML other than APL, randomized studies have validated MRD-based risk-stratified treatment algorithms in acute lymphoblastic leukemia. Here, we review the available studies examining MRD-directed therapy in AML, appraise their strengths and limitations, and discuss avenues for future investigation. PMID:27269126

  11. Evidence of Acute Mycoplasma Infection in a Patient with Incomplete and Atypical Kawasaki Disease: A Case Report

    M. Ebrahim

    2011-01-01

    Full Text Available The etiology of Kawasaki disease remains unknown despite extensive studies. Some researchers suggest that it is caused by an infectious agent. This is a case report where a patient with incomplete Kawasaki disease was found to have evidence compatible with acute Mycoplasma pneumoniae infection. This is one of the several case reports linking Mycoplasma pneumoniae to Kawasaki disease as a possible trigger. This is perhaps due to a superantigen or is mediated by some other mechanism. Accurate and timely testing for Mycoplasma infections is difficult and has its limitations. Despite this, Mycoplasma pneumoniae should be considered in the differential and workup for Kawasaki disease.

    Chronic neurodegenerative diseases such as prion disease and Alzheimer's disease (AD) are reported to be associated with microglial activation and increased brain and serum cytokines and acute-phase proteins (APPs). Unlike AD, prion disease is also associated with a peripheral component in that the presumed causative agent, PrPSc, also accumulates in the spleen and other lymphoreticular organs. It is unclear whether the reported systemic acute-phase response represents a systemic inflammatory...

  15. Contemporary Management of Coronary Artery Disease and Acute Coronary Syndrome in Patients with Chronic Kidney Disease and End-Stage Renal Disease

    Huang, Chin-Chou; Chen, Jaw-Wen

    2013-01-01

    Chronic kidney disease (CKD) and end-stage renal disease (ESRD) have emerged as a worldwide public health problem. Due to the remarkably higher incidence and prevalence of this chronic disease in Taiwan than in other countries, CKD/ESRD has contributed to a significant health burden in Taiwan. Patients with CKD/ESRD have an increased risk of coronary artery disease (CAD) and acute coronary syndrome (ACS) compared to the normal population. Patients with ACS alone can present differently than patients with ACS and CKD/ESRD. Also, due to the lower prevalence of chest pain and ST-segment elevation, CKD/ESRD patients were more difficult to diagnose than other patients. Furthermore, whether advances in ACS management with medical therapy and an early invasive approach could improve patient outcomes with CKD/ESRD is not known. The use of antiplatelets such as aspirin and other antithrombotic agents might reduce the incidence of ACS or stroke in CKD patients. However, such use could also increase bleeding risk and even increase the likelihood of mortality, especially in dialysis patients. While recent clinical data suggest the potential benefit of aggressive management with coronary intervention for CAD and ACS in this category of patients, further clinical studies are still indicated for the proper medical strategy and revascularization therapy to improve the outcomes of CAD and ACS in CKD/ESRD patients, both in Taiwan and worldwide.

  19. Spatiotemporal analysis of reported cases of acute Chagas disease in the State of Pernambuco, Brazil, from 2002 to 2013

    Fred Luciano Neves Santos

    2015-04-01

    Full Text Available INTRODUCTION: Control strategies to eliminate the transmission of Chagas disease by insect vectors have significantly decreased the number of reported acute cases in Brazil. However, data regarding the incidence and distribution of acute Chagas disease cases in the State of Pernambuco are unavailable in the literature. METHODS: A geographical information system was used to delineate the spatiotemporal distribution profile of the cases from 2002 to 2013 in 185 municipalities of Pernambuco based on the municipality where notification occurred. The results were presented in digital maps generated by the TerraView software (INPE. RESULTS: A total of 302 cases of acute disease were recorded in 37.8% of the municipalities, for a total of 0.13 cases per 1,000,000 inhabitants per year. Out of the 302 cases, 99.3% were reported between 2002 and 2006. The most affected municipalities were Carnaubeira da Penha, Mirandiba and Terra Nova. The risk maps showed a significant decrease in the number of notifications and a concentration of cases in the Midwest region. CONCLUSIONS: This study highlights a significant decrease in new cases of acute Chagas disease in Pernambuco starting in 2006 when Brazil received an international certification for the interruption of vectorial transmission by Triatoma infestans. However, control strategies should still be encouraged because other triatomine species can also transmit the parasite; moreover, other transmission modes must not be neglected.

    Coronary artery aneurysms that occur in 25% of untreated Kawasaki disease (KD) patients may remain clinically silent for decades and then thrombose resulting in myocardial infarction. Although KD is now the most common cause of acquired heart disease in children in Asia, the United States, and Western Europe, the incidence of KD in Egypt is unknown. We tested the hypothesis that young adults in Egypt presenting with acute myocardial ischemia may have coronary artery lesions because of KD in childhood. We reviewed a total of 580 angiograms of patients ≤40 years presenting with symptoms of myocardial ischemia. Coronary artery aneurysms were noted in 46 patients (7.9%), of whom 9 presented with myocardial infarction. The likelihood of antecedent KD as the cause of the aneurysms was classified as definite (n = 10), probable (n = 29), or equivocal (n = 7). Compared with the definite and probable groups, the equivocal group had more traditional cardiovascular risk factors, smaller sized aneurysms, and fewer coronary arteries affected. In conclusion, in a major metropolitan center in Egypt, 6.7% of adults aged ≤40 years who underwent angiography for evaluation of possible myocardial ischemia had lesions consistent with antecedent KD. Because of the unique therapeutic challenges associated with these lesions, adult cardiologists should be aware that coronary artery aneurysms in young adults may be because of missed KD in childhood.

  8. Proposal for the standardization of flow cytometry protocols to detect minimal residual disease in acute lymphoblastic leukemia

    Maura Rosane Valério Ikoma

    2015-12-01

    Full Text Available ABSTRACT Minimal residual disease is the most powerful predictor of outcome in acute leukemia and is useful in therapeutic stratification for acute lymphoblastic leukemia protocols. Nowadays, the most reliable methods for studying minimal residual disease in acute lymphoblastic leukemia are multiparametric flow cytometry and polymerase chain reaction. Both provide similar results at a minimal residual disease level of 0.01% of normal cells, that is, detection of one leukemic cell in up to 10,000 normal nucleated cells. Currently, therapeutic protocols establish the minimal residual disease threshold value at the most informative time points according to the appropriate methodology employed. The expertise of the laboratory in a cancer center or a cooperative group could be the most important factor in determining which method should be used. In Brazil, multiparametric flow cytometry laboratories are available in most leukemia treatment centers, but multiparametric flow cytometry processes must be standardized for minimal residual disease investigations in order to offer reliable and reproducible results that ensure quality in the clinical application of the method. The Minimal Residual Disease Working Group of the Brazilian Society of Bone Marrow Transplantation (SBTMO was created with that aim. This paper presents recommendations for the detection of minimal residual disease in acute lymphoblastic leukemia based on the literature and expertise of the laboratories who participated in this consensus, including pre-analytical and analytical methods. This paper also recommends that both multiparametric flow cytometry and polymerase chain reaction are complementary methods, and so more laboratories with expertise in immunoglobulin/T cell receptor (Ig/TCR gene assays are necessary in Brazil.

    2016-06-01

    The objective of the study was to identify risk factors for acute exacerbation of interstitial lung disease (ILD) during tocilizumab treatment in patients with rheumatoid arthritis (RA). This is a retrospective, case-control study. We reviewed 395 consecutive RA patients who received tocilizumab. First, we divided the patients according to the presence (RA-ILD) or absence of ILD (non-ILD) assessed by chest X-ray or high-resolution computed tomography, and compared them for characteristics relevant to RA-ILD. Subsequently, focusing on the patients with RA-ILD, we assessed their baseline characteristics and clinical courses comparing patients with acute exacerbation to those without. Comparing 78 with ILD and 317 without ILD, the following were identified as factors related to RA-ILD on multivariate analysis: age 60 years or older (OR 4.5, 95 % CI 2.2-9.4, P smoking habit (OR 2.9, 95 % CI 1.5-5.5, P = 0.002), and high rheumatoid factor levels (OR 2.8, 95 % CI 1.4-5.5, P = 0.002). Of 78 RA-ILD patients, six developed acute exacerbation during tocilizumab treatment. The median duration between the initiation of tocilizumab treatment and the acute exacerbation occurrence was 48 weeks. While baseline characteristics did not differ between acute exacerbation and non-acute exacerbation groups, patients experiencing acute exacerbation had significantly higher Clinical Disease Activity Index (CDAI) at 24 weeks (20.8 vs. 6.2, P = 0.019). Univariate analysis showed that CDAI > 10 at 24 weeks was a risk factor for acute exacerbation (OR 4.7, 95 % CI 2.1-10.4, P = 0.02). Uncontrolled arthritis activity during tocilizumab treatment may be associated with acute exacerbation of RA-ILD, suggesting post-treatment monitoring of disease activity is important not only with respect to RA itself but also for RA-ILD.

    Members of the bacterial genus Francisella are highly virulent and infectious pathogens. New models to study Francisella pathogenesis in evolutionarily distinct species are needed to provide comparative insight, as the mechanisms of host resistance and pathogen virulence are not well understood. We took advantage of the recent discovery of a novel species of Francisella to establish a zebrafish/Francisella comparative model of pathogenesis and host immune response. Adult zebraflsh were susceptible to acute Francisella-induced disease and suffered mortality in a dose-dependent manner. Using immunohistochemical analysis, we localized bacterial antigens primarily to lymphoid tissues and livers of zebraflsh following infection by intraperitoneal injection, which corresponded to regions of local cellular necrosis. Francisella sp. bacteria replicated rapidly in these tissues beginning 12 h postinfection, and bacterial titers rose steadily, leveled off, and then decreased by 7 days postinfection. Zebraflsh mounted a significant tissue-specific proinflammatory response to infection as measured by the upregulation of interleukin-l?? (IL-1??), gamma interferon, and tumor necrosis factor alpha mRNA beginning by 6 h postinfection and persisting for up to 7 days postinfection. In addition, exposure of zebraflsh to heat-killed bacteria demonstrated that the significant induction of IL-?? was highly specific to live bacteria. Taken together, the pathology and immune response to acute Francisella infection in zebraflsh share many features with those in mammals, highlighting the usefulness of this new model system for addressing both general and specific questions about Francisella host-pathogen interactions via an evolutionary approach.

  11. Dynamics of ceruloplasmin amd of some blood parameters in piglets suffering from acute radiation disease

    Changes in oxidase activity of ceruloplasmin (CP) were followed up after treatment with gamma rays of 60Co with a dose of 4 Ey (dose power 0.68 Ey/min) in the blood serum of male piglets of an average life weight of 18+-3 kg. CP level from 217 E/l raised to 376 E/l on the 16th hour after radiation and on the 16th day decreased to 296 e/l. Moreover, serum copper increased from 25 μmol/l to 42.3 μmol/l on the 16th hour following irradiation but on the 14th day its level dropped to 32.5 μmol/l. Erythrocyte and leucocyte count decreased from 5.83x1012/l and 19.94x1012/l to 2.47x1012/l and 2.0x109/l, respectively. Besides, serum albumin decreased, but α-and β-globulins increased. Examination of ailing piglets showed a paraclinical pattern of an inflammatory process by acute radiation disease. CP as an antioxidant participates in reactions with toxic radiacals on radiation. By the rising of its level on radiation it again was characterized as an acute-phase protein. Serum CP was determined according to the method of Ravin using as substrate P-phenylendiamine dihydrochloride; serum copper - by the test of Boehringer Mannheim; serum proteins were studied electrophoretically on agarose gels using veronal buffer, pH 8.6

  12. Dynamics of peripheral blood lymphocyte subpopulations in the acute and subacute phase of Legionnaires' disease.

    Cornelis P C de Jager

    Full Text Available STUDY OBJECTIVE: Absolute lymphocytopenia is recognised as an important hallmark of the immune response to severe infection and observed in patients with Legionnaires' disease. To explore the immune response, we studied the dynamics of peripheral blood lymphocyte subpopulations in the acute and subacute phase of LD. METHODS AND RESULTS: EDTA-anticoagulated blood was obtained from eight patients on the day the diagnosis was made through detection of L. pneumophila serogroup 1 antigen in urine. A second blood sample was obtained in the subacute phase. Multiparametric flow cytometry was used to calculate lymphocyte counts and values for B-cells, T-cells, NK cells, CD4+ and CD8+ T-cells. Expression of activation markers was analysed. The values obtained in the subacute phase were compared with an age and gender matched control group. Absolute lymphocyte count (×10⁹/l, median and range significantly increased from 0.8 (0.4-1.6 in the acute phase to 1.4 (0.8-3.4 in the subacute phase. B-cell count showed no significant change, while T-cell count (×10⁶/l, median and range significantly increased in the subacute phase (495 (182-1024 versus 979 (507-2708, p = 0.012 as a result of significant increases in both CD4+ and CD8+ T-cell counts (374 (146-629 versus 763 (400-1507, p = 0.012 and 119 (29-328 versus 224 (107-862, p = 0.012. In the subacute phase of LD, significant increases were observed in absolute counts of activated CD4+ T-cells, naïve CD4+ T-cells and memory CD4+ T-cells. In the CD8+ T-cell compartment, activated CD8+ T-cells, naïve CD8+ T-cell and memory CD8+ T-cells were significantly increased (p<0.05. CONCLUSION: The acute phase of LD is characterized by absolute lymphocytopenia, which recovers in the subacute phase with an increase in absolute T-cells and re-emergence of activated CD4+ and CD8+ T cells. These observations are in line with the suggested role for T-cell activation in the immune response to LD.

    Although coffee is a widely used, pharmacologically active beverage, its impact on the cardiovascular system is controversial. To explore the effect of acute caffeine ingestion on brachial artery flow-mediated dilation (FMD) in subjects without coronary artery disease (CAD; controls) and patients with CAD, we prospectively assessed brachial artery FMD in 40 controls and 40 age- and gender-matched patients with documented stable CAD on 2 separate mornings 1 week to 2 weeks apart. After overnight fasting, discontinuation of all medications for ≥12 hours, and absence of caffeine for >48 hours, participants received capsules with caffeine 200 mg or placebo. One hour after drug ingestion, participants underwent brachial artery FMD and nitroglycerin-mediated dilation (NTG) using high-resolution ultrasound. As expected, patients with CAD were more often diabetic, hypertensive, obese, dyslipidemic, and smoked more than controls (p <0.01 for all comparisons). Aspirin, Clopidogrel, angiotensin-converting enzyme inhibitors, β blockers, and statins were significantly more common in patients with CAD than in controls (p <0.01 for all comparisons). At baseline, FMD, but not NTG, was significantly lower in patients with CAD compared to controls. Acute caffeine ingestion significantly increased FMD (patients with CAD 5.6 ± 5.0% vs 14.6 ± 5.0%, controls 8.4 ± 2.9% vs 18.6 ± 6.8%, p <0.001 for all comparisons) but not NTG (patients with CAD 13.0 ± 5.2% vs 13.8 ± 6.1%, controls 12.9 ± 3.9% vs 13.9 ± 5.8%, p = NS for all comparisons) and significantly decreased high-sensitivity C-reactive protein (patients with CAD 2.6 ± 1.4 vs 1.4 ± 1.2 mg/L, controls 3.4 ± 3.0 vs 1.2 ± 1.0 mg/L, p <0.001 for all comparisons) in the 2 groups compared to placebo. In conclusion, acute caffeine ingestion significantly improved endothelial function assessed by brachial artery FMD in subjects with and without CAD and was associated with lower plasma markers of inflammation.

  14. Acute Modulation of Brain Connectivity in Parkinson Disease after Automatic Mechanical Peripheral Stimulation: A Pilot Study.

    Carlo Cosimo Quattrocchi

    Full Text Available The present study shows the results of a double-blind sham-controlled pilot trial to test whether measurable stimulus-specific functional connectivity changes exist after Automatic Mechanical Peripheral Stimulation (AMPS in patients with idiopathic Parkinson Disease.Eleven patients (6 women and 5 men with idiopathic Parkinson Disease underwent brain fMRI immediately before and after sham or effective AMPS. Resting state Functional Connectivity (RSFC was assessed using the seed-ROI based analysis. Seed ROIs were positioned on basal ganglia, on primary sensory-motor cortices, on the supplementary motor areas and on the cerebellum. Individual differences for pre- and post-effective AMPS and pre- and post-sham condition were obtained and first entered in respective one-sample t-test analyses, to evaluate the mean effect of condition.Effective AMPS, but not sham stimulation, induced increase of RSFC of the sensory motor cortex, nucleus striatum and cerebellum. Secondly, individual differences for both conditions were entered into paired group t-test analysis to rule out sub-threshold effects of sham stimulation, which showed stronger connectivity of the striatum nucleus with the right lateral occipital cortex and the cuneal cortex (max Z score 3.12 and with the right anterior temporal lobe (max Z score 3.42 and of the cerebellum with the right lateral occipital cortex and the right cerebellar cortex (max Z score 3.79.Our results suggest that effective AMPS acutely increases RSFC of brain regions involved in visuo-spatial and sensory-motor integration.This study provides Class II evidence that automatic mechanical peripheral stimulation is effective in modulating brain functional connectivity of patients with Parkinson Disease at rest.Clinical Trials.gov NCT01815281.

    Atrial fibrillation(AF) is the most common type of sustained arrhythmia,which is now on course to reach epidemic proportions in the elderly population. AF is a commonly encountered comorbidity in patients with cardiac and major non-cardiac diseases. Morbidity and mortality associated with AF makes it a major healthcare burden. The objective of our article is to determine the prognostic impact of AF on acute coronary syndromes,heart failure and chronic kidney disease. Multiple studies have been conducted to determine if AF has an independent role in the overall mortality of such patients. Our review suggests that AF has an independent adverse prognostic impact on the clinical outcomes of acute coronary syndromes,heart failure and chronic kidney disease.

  17. Life Saving Plasmapheresis for the Management of Hemolytic Crisis and Acute Liver Failure in Wilson’s Disease

    Mohammad Reza Pashaei

    2009-06-01

    Full Text Available Wilson's disease, caused by a deficient cellular copper export system, is transmitted as an autosomal recessive inherited disorder and results in copper accumulation in liver and other organs, particularly in brain. Acute hepatic failure and severe Coombs' negative hemolysis may occur in the course of the disease which has a poor prognosis and most patients do not survive the crisis. Only liver transplantation has been recommended as an effective medical intervention. Herein, we presented a 25-year-old woman with impaired consciousness, acute hepatic failure and hemolysis who was treated with plasmapheresis and albumin replacement. Beside improvement in medical condition, serum copper and hemolysis decreased significantly and renal function was preserved. We concluded that plasmapheresis may be a life saving intervention during fulminant hepatic failure of Wilson's disease.

    BACKGROUND: Diabetes mellitus is one of the risk factors in patients with acute cerebral disease, and always leads to stroke or get it worse. There is often a high level of blood glucose in those patients with diabetes mellitus and cerebral disease, but it is hard to distinguish from both kinds of hyperglycemia. Serum fructosamine is said to be correlated with blood glucose.OBJECTIVE: To explore the relationship between serum fructosamine and blood glucose in patients with acute cerebrovascular disease.DESTGN: A case-controlled study.SETTINGS: Department of Clinical Laboratory, Health Department for Cadres and Department of Neurology of Affiliated Hospital, Qingdao University Medical College.PARTICIPANTS: Forty-eight inpatients and outpatients with cerebrovascular diseases were selected from the Department of Neurology, Affiliated Hospital of Qingdao University Medical College from December 2004 to April 2005. All the patients were confirmed with CT and MRI. There were 25 patients with diabetes mellitus secondary cerebrovascular diseases, who met the diagnostic standards of diabetes mellitus set by WHO,including 12 males and 13 females with an average of (60±8) years old, the course of diabetes mellitus ranged from 1 to 21 years.. The other 23 patients had no diabetes mellitus (without diabetes mellitus group), including 14 males and 9 females with an average of (62±6) years old. Meanwhile, another 50 healthy physical examinees in the hospital were selected as control group, including 26 males and 24 females with the average age of (62±5) years old. Informed content was obtained from all the participants.METHODS: Venous blood was drawn from all the participants, and content of blood glucose was assayed by means of glucose oxidase, and the concentration of serum fructosamine was determined by nitroblue tetrazolium colorimetric method. Comparison between groups was performed by the analysis of variance and q test, and the correlation was tested by linear

  1. Acute and subacute non-infectious lung diseases. Usefulness of HRCT for evaluation of activity especially in follow-up

    The purpose of this study was to survey the usefulness of high-resolution CT (HRCT) for the evaluation of activity in acute and subacute non-infectious diffuse infiltrative lung diseases before and after corticosteroid treatment. Sequential HRCT images and chest radiographs obtained before and after treatment were retrospectively evaluated in 33 patients with acute or subacute non-infectious diffuse infiltrative lung diseases. All these patients were histologically confirmed to have pulmonary Inflammation and to have responded to treatment with corticosteroid. Radiographic and CT scores were correlated with the degree of dyspnea and the results of arterial blood gas analysis using Spearman's rank-correlation coefficient. On follow-up HRCT, the profusion score of areas with increased attenuation was significantly correlated with arterial oxygen tension (PaO2) (p=.003, r=-.53) and the alveolar-arterial oxygen tension difference (AaDO2) (p=.001, r=.57). No other correlation was found after treatment. Nodular and linear opacities were more commonly seen on follow-up chest radiographs and HRCT images than on initial ones. HRCT is useful for the evaluation of disease activity in acute and subacute non-infectious infiltrative lung diseases before and after treatment if paying special attention to the profusion of ground-glass attenuation. Even if pretreatment HRCT has not been performed, posttreatment HRCT should be examined. (author)

  3. Acute chest syndrome of sickle cell disease: radiographic and clinical analysis of 70 cases

    Background. Acute chest syndrome (ACS) is a pulmonary illness with fever, chest pain, leukocytosis and new pulmonary opacity in a patient with sickle cell disease. It is a common reason for hospitalization in sickle cell patients, and a significant cause of mortality. The etiology of ACS is unclear. Lung or bone infarction and infection, among other possible causes, have been proposed. Objective. We reviewed the chest radiographs and medical records of 41 patients with 70 episodes of ACS and correlated the clinical and radiographic courses in an attempt to better characterize and understand the syndrome. Results. In 87 % of episodes, no identifiable etiology of ACS was found. This group of patients had a median age of 14 years and showed dramatic clinical and radiographic improvement within 24 h of therapy. In the remainder of episodes (13 %), an identifiable etiology was found, usually bacterial pneumonia. These patients were younger than the group without an identifiable etiology (median age 2 years) and had a prolonged radiographic course of illness. Conclusion. The chest radiographs of children with ACS without an identifiable etiology have an extremely typical appearance and evolution. Only in cases which do not have this typical pattern should infection be suspected as the underlying cause. (orig.). With 3 figs

    Full Text Available Objective: The aim of this study was to evaluate the differential vulnerability of children in relation to environmental sanitation conditions.Methods: An ecological study was conducted about the association between the trend in rates of hospitalization for acute diarrheal disease (ADD and the population covered by basic sanitation in Brazil by Brazilian states, and stratified by age. The polynomial regression model was used to assess trends. Results: Using data from sanitation coverage and hospitalization rate for ADD, an inverse correlation was found between the two variables, with the correlation having greater magnitude and statistical significance for children (adults: r = -0.259, p = 0.184; children: r = -0.406, p = 0.032. Moreover, there was a statistically significant association for the number of hospitalizations for ADD in children, including the global data for Brazil (SIR = 3.17, 95 % CI 2.95 to 3.42. Conclusions: Improved knowledge and information about children and their windows of susceptibility to environmental agents will help to identify susceptible subgroups and ages, as well as to plan specific preventive measures.

    Full Text Available Antimicrobial resistance is one of the most important problems in public health, veterinary medicine and aquaculture. Importantly, plasmid mediated antibiotic resistance of pathogenic Vibrio parahaemolyticus from shrimp can potentially be transferred through transposition, conjugation and plasmid uptake to different bacterial species in aquaculture systems. In this study, we evaluated the antibiotic resistance pattern in V. parahaemolyticus strains associated with acute hepatopancreatic necrosis disease (AHPND from penaeid shrimp and identified AHPND strains from Mexico showed a high level of resistance to tetracycline (≥5 μg/mL and have the tetB gene coding tetracycline resistance. In particular, the tetB gene was carried in a single copy plasmid (named as pTetB-VA1 comprising 5162-bp with 40% G + C content from the strain (13-511/A1. The plasmid pTetB-VA1 consists of 9 ORFs encoding tetracycline resistant and repressor proteins, transcriptional regulatory proteins and transposases and showed a 99% sequence identity to other tet gene plasmids (pIS04_68 and pAQU2.

    2014-01-01

    Background Military recruits are at a higher risk of acute respiratory disease (ARD) and the causative agents might change over time, which needs to be investigated. Methods The nasopharyngeal swabs and blood samples were consecutively collected from conscripts for three years in a military training center. The real-time lfuorescent quantitative PCR assays were conducted for 15 species of common respiratory pathogens; the serum anti-Legionella pneumophila antibodies were detected by indirect immunolfuorescence (IIF) assay, and serum anti-Microplasma pneumoniae antibodies, serum anti-in-lfuenza B virus and anti-inlfuenza A virus-IgM and IgG were detected by ELISA. Results The prevalences of ARD were 59.3% (108/182) in 2008, 23.3% (50/215) in 2009,and 19.6% (40/204) in 2010. Among the patients with ARD from 2008 to 2010, the inlfuenza B virus infection accounted for 45.4%, 30.0% and 55.0%, and seasonal inlfuenza A virus infection for 8.3%, 8.0% and 5.0%, respectively; the positive rates of serum anti-Legionella pneumophila and anti-Microplasma pneumoniae antibodies in recruits was lower than 10% each year respectively in the three years without diagnostic signiifcance. Conclusion The early appropriate diagnosis and treatment of ARD in military personnel will ensure the power strength of armed forces.

  8. Current Strategies for the Detection of Minimal Residual Disease in Childhood Acute Lymphoblastic Leukemia

    2016-01-01

    Acute lymphoblastic leukemia (ALL) is the most common cancer in children. Current treatment strategies for childhood ALL result in long-term remission for approximately 90% of patients. However, the therapeutic response is worse among those who relapse. Several risk stratification approaches based on clinical and biological aspects have been proposed to intensify treatment in patients with high risk of relapse and reduce toxicity on those with a greater probability of cure. The detection of residual leukemic cells (minimal residual disease, MRD) is the most important prognostic factor to identify high-risk patients, allowing redefinition of chemotherapy. In the last decades, several standardized research protocols evaluated MRD using immunophenotyping by flow cytometry and/or real-time quantitative polymerase chain reaction at different time points during treatment. Both methods are highly sensitive (10−3 a 10−5), but expensive, complex, and, because of that, require qualified staff and frequently are restricted to reference centers. The aim of this article was to review technical aspects of immunophenotyping by flow cytometry and real-time quantitative polymerase chain reaction to evaluate MRD in ALL. PMID:27158437

    Conclusions: Acute PID is common among young, single women with multiple sexual partners, who should be regularly screened for the various sexually transmissible infections. The micro-organisms frequently responsible for acute PID were genital tract mycoplasmas, whose identification should be included among the routine tests done to women with acute PID. Cases of acute PID due to intra-uterine procedures reminds us that adequate asepsis should be observed during these procedures. [Int J Reprod Contracept Obstet Gynecol 2015; 4(3.000: 809-813

    Chronic inflammatory disorders are thought to arise due to an interplay between predisposing host genetics and environmental factors. For example, the onset of inflammatory bowel disease is associated with enteric proteobacterial infection, yet the mechanistic basis for this association is unclear. We have shown previously that genetic defiency in TLR1 promotes acute enteric infection by the proteobacteria Yersinia enterocolitica. Examining that model further, we uncovered an altered cellular immune response that promotes the recruitment of neutrophils which in turn increases metabolism of the respiratory electron acceptor tetrathionate by Yersinia. These events drive permanent alterations in anti-commensal immunity, microbiota composition, and chronic inflammation, which persist long after Yersinia clearence. Deletion of the bacterial genes involved in tetrathionate respiration or treatment using targeted probiotics could prevent microbiota alterations and inflammation. Thus, acute infection can drive long term immune and microbiota alterations leading to chronic inflammatory disease in genetically predisposed individuals.

    Background: Minimal residual disease (MRD) studies in adult acute lymphoblastic leukemia (ALL) give highly significant prognostic information superior to other standard criteria as Minimal residual disease; age, gender and total leucocytic count (TLC) in distinguishing patients at high and low risk of Flow cytometry relapse. Objectives: We aimed to determine the value of MRD monitoring by flow cytometry (FCM) in predicting outcome in adult Precursor ALL patients. Patients and methods: Bone marrow (BM) samples were analyzed by 4-color FCM collected at diagnosis and after induction therapy (MRD1) to correlate MRD positivity with disease free survival (DFS) and overall survival (OS). Results: Study included 57 adult ALL patients (44 males and 13 females) with a median age of 22 years (18-49). DFS showed no significant difference with age, gender and initial TLC (p = 0.838, 0.888 and 0.743, respectively). Cumulative DFS at 2 years was 34% for B-lineage ALL (n: 35) and 57% for T-lineage ALL (n: 18) (p = 0.057). Cumulative DFS at 2 years was M.A. Samra et al. 136 7% for MRD1 positive (high risk, HR) versus 57% for MRD1 negative patients (Low risk, LR) (p < 0.001). Cumulative DFS at 2 years was 29% for HR patients (n: 26) versus 55% for LR (n: 27) according to GMALL classification (p = 0.064). Cumulative OS did not differ according to age, gender and TLC (p = 0.526, 0.594 and 0.513, respectively). Cumulative OS at 2 years was 36% for B ALL (n: 39) versus 77% for TALL (n: 18) (p = 0.016) and was 49% for Philadelphia chromosome (Ph) negative patients versus 0% for Ph-positive patients (p < 0.001). Regarding MRD1, OS at 2 years was 18% for MRD1 HR (n:17) versus 65% for MRD1 LR (n: 38) (p < 0.001). OS was 35% for high-risk patients (n: 30) and 62% for low-risk patients (n: 27) classified according to GMALL risk stratification (p = 0.017). Conclusion: MRD by FCM is a strong independent predictor of outcome in terms of DFS and OS and is a powerful informative parameter in

    We previously showed that kidney dysfunction/interstitial fibrosis by folate predisposes mice to sepsis mortality (normal/sepsis: 15%; folate/sepsis: 90%); agents that increased survival in normal septic mice were ineffective in the two-stage model. We used a recently characterized 5/6 nephrectomy (Nx) mouse model of progressive chronic kidney disease (CKD) to study how CKD impacts sepsis and acute kidney injury (AKI) induced by cecal ligation-puncture (CLP). CKD intensified sepsis severity (...

    2012-01-01

    Introduction. Arterial blood gas (ABG) analyses have an important role in the assessment and monitoring of the metabolic and oxygen status of patients with acute exacerbation of chronic obstructive pulmonary disease (COPD). Arterial puncture could have a lot of adverse effects, while sampling of venous blood is simpler and is not so invasive. Objective. The aim of this study was to evaluate whether venous blood gas (VBG) values of pH, partial pressure of carbon dioxide (PCO2), partial o...

    2004-01-01

    Acute graft-versus-host disease (GVHD) and leukemic relapse are the two major obstacles to successful outcomes after allogeneic bone marrow transplantation (BMT), an effective therapy for hematological malignancies. Several studies have demonstrated that the dysregulation of proinflammatory cytokines and the loss of gastrointestinal tract integrity contribute to GVHD, whereas the donor cytotoxic responses are critical for graft-versus-leukemia (GVL) preservation. Suberoylanilide hydroxamic ac...

    2012-01-01

    At the end of 2005, an outbreak of fever associated with joint pain occurred in La Réunion. The causal agent, chikungunya virus (CHIKV), has been known for 50 years and could thus be readily identified. This arbovirus is present worldwide, particularly in India, but also in Europe, with new variants returning to Africa. In humans, it causes a disease characterized by a typical acute infection, sometimes followed by persistent arthralgia and myalgia lasting months or years. Investigations in t...

    Costa, Daniela Caetano; Rocha, Eduardo; Ribeiro, Tatiane Flores

    2009-06-01

    The acute respiratory distress syndrome is the clinical presentation of acute lung injury characterized by diffuse alveolar damage and development of non-cardiogenic pulmonary edema due to increased pulmonary alveolar-capillary membrane permeability. Alveolar recruitment maneuvers and prone position can be used in the treatment of acute respiratory distress syndrome. The objective of this review of literature was to identify possible benefits, indications, complications and care of the associated recruitment maneuvers and prone position for treatment of the acute respiratory distress syndrome. This national and international scientific literature review was developed according to the established criteria for searching the databases MedLine, LILACS, SciElo, PubMed, Cochrane, from 1994 to 2008 in Portuguese and English, with the key words: acute respiratory distress syndrome, alveolar recruitment maneuver and prone position. Despite advances in the understanding of acute respiratory distress syndrome pathophysiology, mortality is still expressive. Alveolar recruitment maneuvers and prone position significantly contribute to treatment of acute respiratory distress syndrome patient aiming to improve oxygenation and minimizing complications of refractory hypoxemia and reduction of pulmonary compliance. However,as there are few studies in literature associating alveolar recruitment maneuvers and prone position for treatment of acute respiratory distress syndrome, additional research and evidences of clinical application are required.

  6. Kidney Disease and the Nexus of Chronic Kidney Disease and Acute Kidney Injury: The Role of Novel Biomarkers as Early and Accurate Diagnostics.

    Yerramilli, Murthy; Farace, Giosi; Quinn, John; Yerramilli, Maha

    2016-11-01

    Chronic kidney disease (CKD) and acute kidney injury (AKI) are interconnected and the presence of one is a risk for the other. CKD is an important predictor of AKI after exposure to nephrotoxic drugs or major surgery, whereas persistent or repetitive injury could result in the progression of CKD. This brings new perspectives to the diagnosis and monitoring of kidney diseases highlighting the need for a panel of kidney-specific biomarkers that reflect functional as well as structural damage and recovery, predict potential risk and provide prognosis. This article discusses the kidney-specific biomarkers, symmetric dimethylarginine (SDMA), clusterin, cystatin B, and inosine. PMID:27485279

  7. Can cerebral blood flow measurement predict clinical outcome in the acute phase in patients with artherosclerotic occlusive carotid artery disease?

    It has been thought that the clinical course of patients with acute carotid occlusive disease depends on their collateral cerebral blood flow (CBF) and duration of ischemia. However, there have been few clinical reports to prove this hypothesis. Therefore, we performed CBF study in patients with artherosclerotic carotid occlusive disease in the very acute phase, and precisely assessed the prognosis of those patients under intensive medical therapy. This prospective study included a total of 44 patients (72±13 years) who were admitted to our hospital between April, 2007 and December, 2008. To evaluate their initial CBF, single photon emission computed tomography (SPECT) studies were performed within 6 hours after the onset. All patients included in this study were medically treated and were periodically followed up by neurological and radiological examination. Moreover, in patients with reduced CBF (ipsilateral CBF/contralateral CBF x 100: %CBF <80%), dobutamine-induce hyperdynamic therapy was performed. Multivariate analysis was performed to detect significant predictors for the occurrence of further cerebral infarction. Multivariate analysis showed that the occurrence of further infarction was associated with older age and smaller %CBF. Of 44 patients, 21 experienced further cerebral infarction within 10 days after onset. Fourteen out of 15 patients with %CBF <60% developed cerebral infarction. This study showed that the prognosis of the patients with artherosclerotic carotid occlusive disease in the acute phase is associated with their initial residual CBFs. It may be difficult to stop the developed cerebral infarction in those patients with %CBF <60% despite intensive medical therapy. (author)

  8. Frequency of Streptococcus pneumonia and Haemophilus influenza in acute exacerbation of chronic obstructive airway disease and their sensitivity to levofloxacin

    Objective: To determine the frequency of Streptococcus pneumoniae and Haemophilus influenzae in acute exacerbation of chronic obstructive pulmonary disease and their sensitivity to levofloxacin. Methods: The cross-sectional study was conducted at the Department of Medicine, AbbasiShaheed Hospital, Karachi, between July 2009 and January 2010. Patients already diagnosed with chronic obstructive pulmonary disease and admitted with symptoms of acute exacerbation were included in the study and their sputum samples were sent for microbiological evaluation. SPSS 16 was used for statistical analysis. Results: Of the total 105 patients in the study, 90 (85.17%) were males. Overall mean age at presentation was 62+-10.2 years. S. pneumoniae was isolated from sputum culture of 33 (31.4%) patients, while 13 (12.4%) patients showed growth of H. influenzae. Out of the 33 sputum specimens of S. pneumoniae, 32 (97.0%) were sensitive to levofloxacin, while 1 (3.0%) was resistant. All the 13 isolates of H. influenzae were sensitive to levofloxacin. Conclusion: S. pneumoniae and H. influenzae are still the most prevalent organisms isolated in acute exacerbation of chronic obstructive pulmonary disease in our population. Levofloxacin is still considered a highly sensitive antibiotic against these common micro-organisms in our population, but S. pneumoniae has started developing resistance against levofloxacin. Therefore, intermittent surveillance regarding development of resistance pattern of common micro-organisms against commonly prescribed antibiotics is required. (author)

    2015-01-01

    Full Text Available Little is known about the inflammatory effects of resistance exercise in healthy and even less in diseased individuals such as cardiac patients. The purpose of this study was to examine the acute pro- and anti-inflammatory responses during resistance exercise (RE in patients with coronary artery disease. Eight low risk patients completed two acute RE protocols at low (50% of 1 RM; 2x18 rps and moderate intensity (75% of 1 RM; 3x8 rps in random order. Both protocols included six exercises and had the same total load volume. Blood samples were obtained before, immediately after and 60 minutes after each protocol for the determination of lactate, TNFα, INF-γ, IL-6, IL-10, TGF-β1, and hsCRP concentrations. IL-6 and IL-10 levels increased (p < 0.05 immediately after both RE protocols with no differences between protocols. INF-γ was significantly lower (p < 0.05 60 min after the low intensity protocol, whereas TGF-β1 increased (p < 0.05 immediately after the low intensity protocol. There were no differences in TNF-& and hs-CRP after both RE protocols or between protocols. The above data indicate that acute resistance exercise performed at low to moderate intensity in low risk, trained CAD patients is safe and does not exacerbate the inflammation associated with their disease.

    2013-01-01

    Objective: To investigate clinical and neuroimaging features of enterovirus71 (EV71) related acute flaccid paralysis in patients with hand-foot-mouth disease. Methods: Nine patients with acute flaccid paralysis met the criterion of EV71 induced hand-foot-mouth disease underwent spinal and brain MR imaging from May 2008 to Sep 2012. Results: One extremity flaccid was found in four cases (3 with lower limb, 1 with upper limb), two limbs flaccid in three cases (2 with lower limbs, 1 with upper limbs), and four limbs flaccid in two cases. Spinal MRI studies showed lesion with high signal in T2-weighted images (T2WI) and low signal T1-weighted images (T1WI) in the spinal cord of all nine cases, and the lesions were mainly in bilateral and unilateral anterior horn of cervical spinal cord and spinal cord below thoracic 9 (T9) level. In addition, the midbrain, pons, and medulla, which were involved in 3 cases with brainstem encephalitis, demonstrated abnormal signal. Moreover, spinal cord contrast MRI studies showed mild enhancement in corresponding anterior horn of the involved side, and strong enhancement in its ventral root. Conclusions:EV71 related acute flaccid paralysis in patients with hand-foot-mouth disease mainly affected the anterior horn regions and ventral root of cervical spinal cord and spinal cord below T9 level. MR imaging could efficiently show the characteristic pattern and extent of the lesions which correlated well with the clinical features.

  11. Some points of the X-ray pattern of acute viral primary pneumonia caused by acute respiratory disease viruses

    An analysis is made of the results of the X-ray studies as well as of the virological and serological tests in 225 out-patients consulted in the first days of their complaints. A predominance of the viral (70.2%) over the viral-bacterial primary pneumonia is established. The acute viral primary pneumonia are caused mostly by single influenza viruses and more rarely - by single respiratory viruses; in the cases of combined influenza viruses influenza-influenza viruses prevail over the influenza-respiratory ones. The morphological changes in pneumonia due to isolated single influenza viruses involve mostly the interstitium and are projected on X-ray as patchy and stripped densities. The inflamatory changes in pneumonia caused by combined influenza viruses affect both ihe interstitium and the broncho-alveolar substrate of the lungs; they are manifested in two roentgenologic forms: creeping (migrating) and fusing (confluent). In viral-bacterial pneumonia the changes affect mostly the lobe. The right lung and the lower parts of the both lungs are affected in most cases. 5 figs., 21 refs

  12. Correlation between arterial and venous blood gas analysis parameters in patients with acute exacerbation of chronic obstructive pulmonary disease

    2012-01-01

    Full Text Available Introduction. Arterial blood gas (ABG analyses have an important role in the assessment and monitoring of the metabolic and oxygen status of patients with acute exacerbation of chronic obstructive pulmonary disease (COPD. Arterial puncture could have a lot of adverse effects, while sampling of venous blood is simpler and is not so invasive. Objective. The aim of this study was to evaluate whether venous blood gas (VBG values of pH, partial pressure of carbon dioxide (PCO2, partial oxygen pressure (PO2, bicarbonate (HCO3, and venous and arterial blood oxygen saturation (SO2 can reliably predict ABG levels in patients with acute exacerbation of COPD. Methods. Forty-seven patients with a prior diagnosis of COPD were included in this prospective study. The patients with acute exacerbation of this disease were examined at the General Hospital EMS Department in Prijepolje. ABG samples were taken immediately after venous sampling, and both were analyzed. Results. The Pearson correlation coefficients between arterial and venous parameters were 0.828, 0.877, 0.599, 0.896 and 0.312 for pH, PCO2, PO2, HCO3 and SO2, respectively. The statistically significant correlation between arterial and venous pH, PCO2 and HCO3, values was found in patients with acute exacerbation of COPD (p<0.001. Conclusion. When we cannot provide arterial blood for analysis, venous values of the pH, Pv,CO2 and HCO3 parameters can be an alternative to their arterial equivalents in the interpretation of the metabolic status in patients with acute exacerbation of COPD, while the values of venous Pv,O2 and Sv,O2 cannot be used as predictors in the assessment of oxygen status of such patients.

    2015-07-01

    Full Text Available Objective To investigate whether 18F-FDG uptake can be applied in dosimetry to facilitate a rapid and accurate evaluation of individual radiation dosage after a nuclear accident. Methods Forty-eight Tibetan minipigs were randomly assigned into 6 groups, i.e., 0, 1, 2, 5, 8 and 11Gy groups. Animals in all except 0Gy group received total body irradiation (TBI with a 8MV X centrifugal linear accelerator, and 18F-FDG combined positron-emission tomography and computed tomography (PET/CT were carried out before TBI, and also at 6, 24 and 72h after receiving TBI in different doses ranging from 1 to 11Gy. Spleen tissues and blood samples were collected for histological examination, apoptosis, and routine blood analysis. Results Mean standardized uptake values (SUVs of the spleen showed significant differences between experimental groups and control group. The spleen SUVs at 6h post-irradiation showed significant correlation with radiation dose; Spearman's correlation coefficient was 0.95(P<0.01. Histopathological observations showed that the degree of splenic damage was proportional to the radiation dose. Moreover, flow cytometry revealed that apoptosis was one of the major forms of splenic lymphocyte death. Conclusion In the Tibetan minipig model, it was shown that radiation doses bear a close relationship with the 18F-FDG uptake of spleen. This finding suggests that 18F-FDG PET/CT may be useful for the rapid detection of individual radiation dosage after acute radiation disease (ARD. DOI: 10.11855/j.issn.0577-7402.2015.07.08

  14. Magnesium for acute exacerbation of chronic obstructive pulmonary disease: A systematic review of randomised trials

    Mitrakrishnan Chrishan Shivanthan

    2014-01-01

    Full Text Available The efficacy of magnesium sulphate in chronic obstructive pulmonary disease (COPD was assessed by conducting a systematic review of published randomized clinical trials through extensive searches in MEDLINE and SCOPUS with no date limits, as well as manual review of journals. Outcome measures varied depending on route(s of administration of magnesium sulphate and medications co-administered. Risk of bias was evaluated and quality of evidence was graded. Four (4 randomized trials were included. All trials had a moderate risk of bias and were of average methodological quality. Magnesium sulphate given intravenously did not seem to have an immediate bronchodilatory effect; however it appears to potentiate the bronchodilatory effect of inhaled beta-2 agonists. Increase in peak expiratory flow rate (PEFR at 30 and 45 min was greater in those who received magnesium sulphate compared to placebo (P = 0.03, although the mean percentage change in PEFR was just 24%, without significant differences in dyspnoea scores, hospital admission rates, or emergency department readmission rates compared to placebo. Nebulized magnesium sulphate with salbutamol versus nebulized salbutamol with saline placebo showed no significant differences is forced expiratory volume in 1 s (FEV 1 measured at 90 min after adjustment for baseline FEV 1 (P = 0.34 or differences in the need for hospital admission. Combined inhalational and intravenous magnesium sulphate versus intravenous saline placebo and nebulized ipratropium bromide were comparable in terms of hospital admission, intubation and death, but the ipratropium bromide group showed better bronchodilator effect and improvement in arterial blood gas parameters. Overall, trial evidence for trial evidence for magnesium sulphate in acute exacerbation of COPD is poor, and further well-designed trials are needed.

  15. Long-Term Outcomes From Acute Rheumatic Fever and Rheumatic Heart Disease

    He, Vincent Y.F.; Condon, John R.; Zhao, Yuejen; Roberts, Kathryn; de Dassel, Jessica L.; Currie, Bart J.; Fittock, Marea; Edwards, Keith N.; Carapetis, Jonathan R.

    2016-01-01

    Background: We investigated adverse outcomes for people with acute rheumatic fever (ARF) and rheumatic heart disease (RHD) and the effect of comorbidities and demographic factors on these outcomes. Methods: Using linked data (RHD register, hospital, and mortality data) for residents of the Northern Territory of Australia, we calculated ARF recurrence rates, rates of progression from ARF to RHD to severe RHD, RHD complication rates (heart failure, endocarditis, stroke, and atrial fibrillation), and mortality rates for 572 individuals diagnosed with ARF and 1248 with RHD in 1997 to 2013 (94.9% Indigenous). Results: ARF recurrence was highest (incidence, 3.7 per 100 person-years) in the first year after the initial ARF episode, but low-level risk persisted for >10 years. Progression to RHD was also highest (incidence, 35.9) in the first year, almost 10 times higher than ARF recurrence. The median age at RHD diagnosis in Indigenous people was young, especially among males (17 years). The development of complications was highest in the first year after RHD diagnosis: heart failure incidence rate per 100 person-years, 9.09; atrial fibrillation, 4.70; endocarditis, 1.00; and stroke, 0.58. Mortality was higher among Indigenous than non-Indigenous RHD patients (hazard ratio, 6.55; 95% confidence interval, 2.45–17.51), of which 28% was explained by comorbid renal failure and hazardous alcohol use. RHD complications and mortality rates were higher for urban than for remote residents. Conclusions: This study provides important new prognostic information for ARF/RHD. The residual Indigenous survival disparity in RHD patients, which persisted after accounting for comorbidities, suggests that other factors contribute to mortality, warranting further research.

    Purpose Gastric fundoplication (GF) for gastroesophageal reflux disease (GERD) may protect against the progression of chronic rejection in lung transplant (LT) recipients. However, the association of GERD with acute rejection episodes (ARE) is uncertain. This study sought to identify if ARE were linked to GERD in LT patients. Methods This single-center retrospective observational study, of patients transplanted from January 1, 2000, to January 31, 2009, correlated results of pH probe testing for GERD with ARE (≥International Society for Heart and Lung Transplantation A1 or B1). We compared the rates of ARE among patients with GERD (DeMeester Score > 14.7) versus without GERD as number of ARE per 1,000 patient-days after LT. Patients undergoing GF prior to LT were excluded. Results The analysis included 60 LT subjects and 9,249 patient-days: 33 with GERD versus 27 without GERD. We observed 51 ARE among 60 LT recipients. The rate of ARE was highest among patients with GERD: 8.49 versus 2.58, an incidence density ratio (IDR) of 3.29 (P = .00016). Upon multivariate negative binomial regression modeling, only GERD was associated with ARE (IDR 2.15; P = .009). Furthermore, GERD was associated with multiple ARE (36.4% vs 0%; P < .0001) and earlier onset compared with patients without GERD: ARE proportion at 2 months was 0.55 versus 0.26 P = .004). Conclusion In LT recipients, GERD was associated with a higher rate, multiple events, and earlier onset of ARE. The efficacy of GF to reduce ARE among patients with GERD needs further evaluation.

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

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

  19. Steroidogenic Acute Regulatory Protein (StAR: Evidence of Gonadotropin-Induced Steroidogenesis in Alzheimer Disease

    2006-10-01

    Full Text Available Abstract Background Alzheimer disease (AD is clinically characterized by progressive memory loss, impairments in behavior, language and visual-spatial skills and ultimately, death. Epidemiological data reporting the predisposition of women to AD has led to a number of lines of evidence suggesting that age-related changes in hormones of the hypothalamic-pituitary-gonadal (HPG axis following reproductive senescence, may contribute to the etiology of AD. Recent studies from our group and others have reported not only increases in circulating gonadotropins, namely luteinizing hormone (LH in individuals with AD compared with control individuals, but also significant elevations of LH in vulnerable neuronal populations in individuals with AD compared to control cases as well as the highest density of gonadotropin receptors in the brain are found within the hippocampus, a region devastated in AD. However, while LH is higher in AD patients, the downstream consequences of this are incompletely understood. To begin to examine this issue, here, we examined the expression levels of steroidogenic acute regulatory (StAR protein, which regulates the first key event in steroidogenesis, namely, the transport of cholesterol into the mitochondria, and is regulated by LH through the cyclic AMP second messenger pathway, in AD and control brain tissue. Results Our data revealed that StAR protein was markedly increased in both the cytoplasm of hippocampal pyramidal neurons as well as in the cytoplasm of other non-neuronal cell types from AD brains when compared with age-matched controls. Importantly, and suggestive of a direct mechanistic link, StAR protein expression in AD brains colocalized with LH receptor expression. Conclusion Therefore, our findings suggest that LH is not only able to bind to its receptor and induce potentially pathogenic signaling in AD, but also that steroidogenic pathways regulated by LH may play a role in AD.

    Objective:To explore the clinical efficacy of budesonide in the treatment of acute exacerbation of chronic obstructive pulmonary disease (AECOPD).Methods:A total of 60 patients with moderate and severe AECOPD who were admitted in our hospital from January, 2015 to January, 2016 were included in the study and randomized into the experiment group and the control group. The patients in the two groups were given oxygen inhalation, anti-infection, phlegm dispersing, ipratropium bromide (0.5 mg/time), and aerosol liquid of salbutamol sulfate (2.5 mg/time), 3 times/d, 20 min/time, aerosol inhalation. The patients in the experiment group were given budesonide (2 mg/time), while the patients in the control group were given budesonide (1 mg/time), every 8 h for one aerosol inhalation. The patients in the two groups were continuously treated for 7 d. The changes of PaO2, PaCO2, FEV1, and FEV1/FVC before and after treatment were detected, and the efficacy was evaluated. Results:After treatment, PaO2 and PaCO2 in the two groups were significantly improved when compared with before treatment, and the improved degree in the observation group was significantly superior to that in the control group. After treatment, FEV1 and FEV1/FVC in the two groups were significantly improved when compared with before treatment, and the improved degree in the observation group was significantly superior to that in the control group. The total effective rate in the observation group (93.33%) was significantly higher than that in the control group (76.67%).Conclusions:Aerosol inhalation of budesonide in the treatment of AECOPD in a large dose for a short term can significantly improve the blood gas and pulmonary function.

    2012-03-01

    Antiplatelet therapy is used widely with proven benefit for the prevention of further ischemic cardiac complications in patients with known coronary artery disease (CAD) and a history of acute coronary syndrome (ACS). The limitations of conventional antiplatelet therapy with aspirin, clopidogrel, or prasugrel, as well as the fact that rates of recurrent ischemic events still remain high with use of these agents, underscore the need to investigate alternate agents that may further reduce event rates while limiting bleeding risk. The selection of antiplatelet therapy is further influenced by the following: ticagrelor was approved in July 2011 by the United States Food and Drug Administration (FDA), and clopidogrel is slated to become available as a generic productin 2012. We provide an overview of emerging agents for the treatment of CAD and ACS, including the reversible P2Y(12) antagonists ticagrelor, cangrelor, and elinogrel, and a new class of oral protease-activated receptor-1 (PAR-1) inhibitors, vorapaxar and atopaxar.The recently approved P2Y(12) antagonists prasugrel and ticagrelor demonstrate enhanced ability to prevent adverse cardiac outcomes. However, this comes at a cost of a potential increased risk of bleeding. New adverse effects have also emerged, including dyspnea for all of the reversible P2Y(12) antagonists (ticagrelor, cangrelor, and elinogrel) and ventricular pauses for ticagrelor. In addition, the newer P2Y(12) antagonists have a faster onset and offset. Two of these agents, cangrelor and elinogrel, are available as intravenous formulations, which may provide additional benefits in patients who undergo coronary artery bypass graft (CABG) surgery. Trials with the PAR-1 inhibitors have also shown trends toward reductions in cardiac events, but not without the possibility of increased bleeding. More than ever, as the arsenal of antiplatelet therapy expands, health care providers need to understand the pharmacologic and pharmacodynamic differences

    Little is known about the inflammatory effects of resistance exercise in healthy and even less in diseased individuals such as cardiac patients. The purpose of this study was to examine the acute pro- and anti-inflammatory responses during resistance exercise (RE) in patients with coronary artery disease. Eight low risk patients completed two acute RE protocols at low (50% of 1 RM; 2x18 rps) and moderate intensity (75% of 1 RM; 3x8 rps) in random order. Both protocols included six exercises and had the same total load volume. Blood samples were obtained before, immediately after and 60 minutes after each protocol for the determination of lactate, TNFα, INF-γ, IL-6, IL-10, TGF-β1, and hsCRP concentrations. IL-6 and IL-10 levels increased (p < 0.05) immediately after both RE protocols with no differences between protocols. INF-γ was significantly lower (p < 0.05) 60 min after the low intensity protocol, whereas TGF-β1 increased (p < 0.05) immediately after the low intensity protocol. There were no differences in TNF-& and hs-CRP after both RE protocols or between protocols. The above data indicate that acute resistance exercise performed at low to moderate intensity in low risk, trained CAD patients is safe and does not exacerbate the inflammation associated with their disease. Key points Acute resistance exercise is safe without exacerbating inflammation in patients with CAD. Both exercise intensities (50 and 75% of 1 RM) elicit desirable pro-and anti-inflammatory responses. With both exercise intensities (50 and 75% of 1 RM) acceptable clinical hemodynamic alterations were observed. PMID:25729295

  7. Factors Influencing the Efficacy of Radiation Protection of the Thyroid Gland in Chernobyl Patients with Acute Radiation Disease

    Full text: Just after the Chernobyl accident there were three groups of factors which could influence on the incorporation of radioactive iodine into the victims at the Chernobyl nuclear power plant. The first group was related with the amount of radioactive iodine in the air, the second with radiation protection measures and the third with clinical condition of the victims. The purpose of this investigation was to study relationships among them. The subject of the research was 108 case histories of the victims after short-term external gamma-exposure from 0.5 to 12.7 Gy. 92 of them fell ill with acute radiation disease. Their thyroid glands were exposed to radiation iodine within 0.01-12 Gy. A multifactor analysis was used for studying the relationships among the radioactive iodine intake, development of prodromal radiation syndrome and taking in 0.125 g of potassium iodine to protect the thyroid gland. The investigation shows that the highest level of iodine incorporation was determined in the men stayed at the nuclear power plant for the first hour after the beginning of the accident. A protective effect of potassium iodine depended on the time of taking in. The vomiting was a reason for decreasing the effect due to the loss of some potassium iodine with vomiting materials during the prodromal period of acute radiation disease. The level of the radionuclide incorporation had no influence on the development of the acute radiation syndrome. (author)

    The purpose of this study was to review unilateral acute maculopathy associated with hand-foot-mouth disease with a representative case. Clinical course of a 24-year-old male case with unilateral acute idiopatic maculopathy documented by multimodal imaging is presented, and a review of similar cases is given. On initial examination, best-corrected visual acuity was 20/200 in the left eye. Fundoscopy revealed grayish-yellowish subretinal exudate, and fluorescein angiography demonstrated irregular mottled hyperfluorescence at the central macula. Spectral domain optical coherence tomography demonstrated disruption of ellipsoid layer, which partially resolved on follow-up examinations. Best-corrected visual acuity increased to 20/20 at 3 months, with persistent retinal changes, and mild disruption of ellipsoid layer and persistent mild metamorphopsia. Although hand-foot-mouth disease is usually benign and self-limited in childhood, it may be rarely associated with unilateral vision loss due to maculopathy, especially at early adulthood in both sexes. Vision loss associated with this eruption is acute and reversible in most cases, despite some residual pigmentary and scarring changes in all cases and persistent mild visual loss in some cases. Exact pathophysiology, the causes of variability of clinical features, adulthood onset, unilateral involvement, and role of multimodal imaging are issues which need to be clarified with further research.

    2013-05-01

    Full Text Available Non-alcoholic fatty liver disease (NAFLD is a slowly progressive chronic disease, with a high prevalence among obese, dyslipidemic or diabetic people, commonly presented as an asymptomatic mild elevation of serum aminotransferases. We report a patient who experienced an acute form of non-alcoholic steatohepatitis, as the first manifestation of NAFLD, due to exacerbation of pre-existing metabolic disorders by an extremely unhealthy lifestyle. A 50-year old, obese, diabetic man presented with a one-week history of jaundice and malaise. Analysis revealed elevated liver enzymes, bilirubin, lipids, and glucose. Based on patient’s history, physical examination, laboratory results, and imaging findings, acute non-alcoholic steatohepatitis was established as a diagnosis of exclusion. The patient was started on a low-calorie diet free of carbohydrates and fats, in combination with insulin. A dramatic improvement of clinical and laboratory parameters was observed. In the context of extreme metabolic dysregulation, induced by unhealthy diet, NAFLD may present as an acute steatohepatitis.

    Duodenal Crohn's disease is rare, and patients without obstruction are treated medically. We herein report one case whose duodenal Crohn's disease was successfully managed with low-speed elemental diet infusion through a nasogastric tube. A 28-year-old female developed acute duodenal Crohn's disease. Upper GI radiologic and endoscopic examinations showed a stricture in the duodenal bulb. Using the duodenal biopsy specimens,mucosal cytokine levels were measured; interleukin (IL)-1β, IL-6, IL-8, and tumor necrosis factor-α levels were remarkably elevated. For initial 2 wk, powdered mesalazine was orally given but it was not effective. For the next 2 wk, she was treated with low-speed elemental diet therapy using a commercially available ElentalTM,which was infused continuously through a nasogastric tube using an infusion pump. The tip of the nasogastric tube was placed at an immediate oral side of the pylorus.The infusion speed was 10 mL/h (usual speed, 100 mL/h).After the 2-wk treatment, her symptoms were very much improved, and endoscopically, the duodenal stricture and inflammation improved. The duodenal mucosal cytokine levels remarkably decreased compared with those before the treatment. Although our experience was limited, lowspeed elemental diet infusion through a nasogastric tube may be a useful treatment for acute duodenal Crohn's disease.

    Objectives To assess the magnitude of difference in antibiotic use between clinical teams in the acute setting and assess evidence for any adverse consequences to patient safety or healthcare delivery. Design Prospective cohort study (1 week) and analysis of linked electronic health records (3 years). Setting UK tertiary care centre. Participants All patients admitted sequentially to the acute medical service under an infectious diseases acute physician (IDP) and other medical teams during 1 week in 2013 (n=297), and 3 years 2012–2014 (n=47 585). Primary outcome measure Antibiotic use in days of therapy (DOT): raw group metrics and regression analysis adjusted for case mix. Secondary outcome measures 30-day all-cause mortality, treatment failure and length of stay. Results Antibiotic use was 173 vs 282 DOT/100 admissions in the IDP versus non-IDP group. Using case mix-adjusted zero-inflated Poisson regression, IDP patients were significantly less likely to receive an antibiotic (adjusted OR=0.25 (95% CI 0.07 to 0.84), p=0.03) and received shorter courses (adjusted rate ratio (RR)=0.71 (95% CI 0.54 to 0.93), p=0.01). Clinically stable IDP patients of uncertain diagnosis were more likely to have antibiotics held (87% vs 55%; p=0.02). There was no significant difference in treatment failure or mortality (adjusted p>0.5; also in the 3-year data set), but IDP patients were more likely to be admitted overnight (adjusted OR=3.53 (95% CI 1.24 to 10.03), p=0.03) and have longer length of stay (adjusted RR=1.19 (95% CI 1.05 to 1.36), p=0.007). Conclusions The IDP-led group used 30% less antibiotic therapy with no adverse clinical outcome, suggesting antibiotic use can be reduced safely in the acute setting. This may be achieved in part by holding antibiotics and admitting the patient for observation rather than prescribing, which has implications for costs and hospital occupancy. More information is needed to indicate whether any such longer admission will

    Full Text Available Introduction: Acute kidney injury (AKI is a frequent and potentially fatal complication in infectious diseases. The aim of this study was to investigate the clinical aspects of AKI associated with infectious diseases and the factors associated with mortality. Methods: This retrospective study was conducted in patients with AKI who were admitted to the intensive care unit (ICU of a tertiary infectious diseases hospital from January 2003 to January 2012. The major underlying diseases and clinical and laboratory findings were evaluated. Results: A total of 253 cases were included. The mean age was 46±16 years, and 72% of the patients were male. The main diseases were human immunodeficiency virus (HIV infection, HIV/acquired immunodeficiency syndrome (AIDS (30%, tuberculosis (12%, leptospirosis (11% and dengue (4%. Dialysis was performed in 70 cases (27.6%. The patients were classified as risk (4.4%, injury (63.6% or failure (32%. The time between AKI diagnosis and dialysis was 3.6±4.7 days. Oliguria was observed in 112 cases (45.7%. The Acute Physiology and Chronic Health Evaluation (APACHE II scores were higher in patients with HIV/AIDS (57±20, p-value=0.01 and dengue (68±11, p-value=0.01. Death occurred in 159 cases (62.8%. Mortality was higher in patients with HIV/AIDS (76.6%, p-value=0.02. A multivariate analysis identified the following independent risk factors for death: oliguria, metabolic acidosis, sepsis, hypovolemia, the need for vasoactive drugs, the need for mechanical ventilation and the APACHE II score. Conclusions: AKI is a common complication in infectious diseases, with high mortality. Mortality was higher in patients with HIV/AIDS, most likely due to the severity of immunosuppression and opportunistic diseases.

    We report here on the MR findings of the first Korean case of hand-foot-mouth disease (HFMD) complicated by acute enterovirus 71 (EV 71) encephalitis in a 33-month old girl. Conventional MR images of the patient showed the increased signal intensity (SI) on a T2-weighted image (WI) at the posterior aspect of the medulla, the pontine tegmen, the bilateral dentate nuclei of the cerebellum and the midbrain. There was no evidence of abnormal SI or contrast enhancement at the same areas of the brain on the pre- and post-contrast T1-WI. The diffusion weighted images (DWI) also revealed the bilateral symmetrical strong high SI at the posterior aspect of the medulla and pontine tegmen and there was low SI at the same areas on the apparent diffusion coefficient (ADC) map. DWI in addition to the conventional MR imaging may be helpful for the early detection of acute EV 71 encephalitis in a patient with HFMD

    2005-01-01

    Full Text Available Background: Noninvasive ventilation (NIV has been shown to be an effective treatment for ventilatory failure, particularly resulting from acute exacerbations of chronic obstructive pulmonary disease (COPD. However, NIV is associated with significant failure rates. Hence, there is a need for identifying preadmission predictors for outcome of NIV in patients for acute exacerbation of COPD, thereby sparing the discomfort of a trial of NIV on these patients. Aim: The study was carried to identify the preadmission predictors of outcome of NIV in acute exacerbation of COPD with respiratory failure. Material and Methods: The study was carried in the Department of TB & Chest diseases at the Jawaharlal Nehru Medical College, AMU; 250 patients with acute exacerbation of COPD were enrolled in the study. These patients were grouped on the basis of six different independent variables, viz. age, performance status, pH, late failures, SaO2, and presence or absence of pedal edema. Analysis was done by z-test, P Observation: Age had no impact on the outcome of patient on NIV ( z = 0.3.The risk for endotracheal intubation was found to be increased by the presence of pedal edema ( z = 6.2; P < 0.001, O2 saturation of less than 86% ( z = 4.7; P < 0.001, and acidemia (pH < 7.3 on admission ( z = 10.6; P < 0.001. In addition, poor performance status of limited self-care ( z = 3.2; P < 0.01 and late failures carried poor outcome of NIV ( z = 8.3; P < 0.001. Conclusion: Patients′ COPD with poor baseline performance status, pedal edema, low oxygen saturation, and academia carry a high likelihood of failure and should be spared a prolonged trial of NIV.

    ELM-2 ELISAs was evaluated in patients with acute myocardial infarction (AMI), no AMI, high coronary calcium, or low coronary calcium. The serological release of ELM-2 in patients with chronic obstructive pulmonary disease (COPD) or idiopathic pulmonary fibrosis (IPF) was compared to controls. RESULTS......BACKGROUND: Elastin is a signature protein of the arteries and lungs, thus it was hypothesized that elastin is subject to enzymatic degradation during cardiovascular and pulmonary diseases. The aim was to investigate if different fragments of the same protein entail different information associated...... correlation was observed between ELM-2 and ELM. ELM-2 was not elevated in the COPD and IPF patients and was not correlated to ELM. ELM was shown to be correlated with smoking habits (p<0.01). CONCLUSIONS: The ELM-2 neoepitope was related to AMI whereas the ELM neoepitope was related to pulmonary diseases...

    Borna disease virus (BDV) is a noncytolytic, neurotropic RNA virus that is known to cause neurological disturbances in various animal species. Our previous experiment demonstrated that neonate gerbils develop an acute fatal neurological disease following infection with BDV , Virology 282, 65-76). The study suggested that BDV directly causes functional damage of neuronal cells resulting in the lethal disorder in neonatal gerbils. To extend this finding, we examined whether BDV can induce neurological diseases in the absence of virus- and immune-mediated cell destruction, by using cyclosporine A (CsA)-treated neonatal gerbils. Although CsA completely suppressed specific antibody production and brain inflammation in the infected gerbil brains, the fatal neurological disorder was not inhibited by the treatment. Furthermore, we demonstrated that CsA treatment significantly decreased brain levels of cytokines, except interleukin (IL)-1β, in the infected gerbils. These results suggested that BDV replication, as well as brain cytokines, at least IL-1β, rapidly induces fatal disturbances in gerbil brain. We demonstrate here that BDV exhibits a unique neuropathogenesis in neonatal gerbil that may be pathologically and immunologically different from those in two other established rodent models, rats and mice. With this novel rodent model of virus infection it should be possible not only to examine acute neurological disturbances without severe neuroanatomical and immunopathological alterations but also to analyze molecular and cellular damage by virus replication in the central nervous system

  2. Possible implication of bacterial infection in acute graft-versus-host disease after allogeneic hematopoietic stem cell transplantation

    Full Text Available Graft-versus-host disease (GVHD is still one of the major causes of morbidity and mortality in allogeneic hematopoietic stem cell transplantation (HSCT. In the pathogenesis of acute GVHD, it has been established that donor-derived T cells activated in the recipient play a major role in GVHD in initiation and maintenance within an inflammatory cascade. To reduce the risk of GVHD, intensification of GVHD prophylaxis like T cell depletion is effective, but it inevitably increases the risk of infectious diseases and abrogates beneficial graft-versus-leukemia effects. Although various cytokines are considered to play an important role in the pathogenesis of GVHD, GVHD initiation is such a complex process that cannot be prevented by means of single inflammatory cytokine inhibition. Thus, efficient methods to control the whole inflammatory milieu both on cellular and humoral view are needed. In this context, infectious diseases can theoretically contribute to an elevation of inflammatory cytokines after allogeneic HSCT and activation of various subtypes of immune effector cells, which might in summary lead to an aggravation of acute GVHD. The appropriate treatments or prophylaxis of bacterial infection during the early phase after allogeneic HSCT might be beneficial to reduce not only infectious-related but also GVHD-related mortality. Here, we aim to review the literature addressing the interactions of bacterial infections and GVHD after allogeneic HSCT.

    Studies developed by our group in the last years have shown the involvement of TGF-β in acute and chronic Chagas heart disease, with elevated plasma levels and activated TGF-β cell signaling pathway as remarkable features of patients in the advanced stages of this disease, when high levels of cardiac fibrosis is present. Imbalance in synthesis and degradation of extracellular matrix components is the basis of pathological fibrosis and TGF-β is considered as one of the key regulators of this process. In the present study, we investigated the activity of the TGF-β signaling pathway, including receptors and signaling proteins activation in the heart of animals experimentally infected with Trypanosoma cruzi during the period that mimics the acute phase of Chagas disease. We observed that T. cruzi-infected animals presented increased expression of TGF-β receptors. Overexpression of receptors was followed by an increased phosphorylation of Smad2/3, p38 and ERK. Furthermore, we correlated these activities with cellular factors involved in the fibrotic process induced by TGF-β. We observed that the expression of collagen I, fibronectin and CTGF were increased in the heart of infected animals on day 15 post-infection. Correlated with the increased TGF-β activity in the heart, we found that serum levels of total TGF-β were significantly higher during acute infection. Taken together, our data suggest that the commitment of the heart associates with increased activity of TGF-β pathway and expression of its main components. Our results, confirm the importance of this cytokine in the development and maintenance of cardiac damage caused by T. cruzi infection. PMID:26852285

  17. Acute plasma biomarkers of T cell activation set-point levels and of disease progression in HIV-1 infection.

    Anne-Sophie Liovat

    Full Text Available T cell activation levels, viral load and CD4(+ T cell counts at early stages of HIV-1 infection are predictive of the rate of progression towards AIDS. We evaluated whether the inflammatory profile during primary HIV-1 infection is predictive of the virological and immunological set-points and of disease progression. We quantified 28 plasma proteins during acute and post-acute HIV-1 infection in individuals with known disease progression profiles. Forty-six untreated patients, enrolled during primary HIV-1 infection, were categorized into rapid progressors, progressors and slow progressors according to their spontaneous progression profile over 42 months of follow-up. Already during primary infection, rapid progressors showed a higher number of increased plasma proteins than progressors or slow progressors. The plasma levels of TGF-β1 and IL-18 in primary HIV-1 infection were both positively associated with T cell activation level at set-point (6 months after acute infection and together able to predict 74% of the T cell activation variation at set-point. Plasma IP-10 was positively and negatively associated with, respectively, T cell activation and CD4(+ T cell counts at set-point and capable to predict 30% of the CD4(+ T cell count variation at set-point. Moreover, plasma IP-10 levels during primary infection were predictive of rapid progression. In primary infection, IP-10 was an even better predictor of rapid disease progression than viremia or CD4(+ T cell levels at this time point. The superior predictive capacity of IP-10 was confirmed in an independent group of 88 HIV-1 infected individuals. Altogether, this study shows that the inflammatory profile in primary HIV-1 infection is associated with T cell activation levels and CD4(+ T cell counts at set-point. Plasma IP-10 levels were of strong predictive value for rapid disease progression. The data suggest IP-10 being an earlier marker of disease progression than CD4(+ T cell counts or

  18. Detection of acute osteomyelitis with indium-111 labeled white blood cells in a patient with sickle cell disease

    A young patient with sickle cell disease (SCD) and multiple hospitalizations for crisis was admitted because of suspected osteomyelitis. Initial laboratory work, radiographs, and bone images were not contributory. An In-111 white blood cell (WBC) study demonstrated two areas of increased radionuclide uptake consistent with osteomyelitis. One of these had associated soft tissue infection. No other areas of active osteomyelitis were visualized, in spite of the presence of several additional infection sites. Imaging with In-111 WBC is probably not justified for routine diagnosis of acute osteomyelitis in areas free of previous disease, where conventional bone images are highly efficient. In-111 WBC imaging, however, may be helpful in detecting osteomyelitis in selected patients with SCD in whom Tc-99m bone images and radiographs are usually abnormal and difficult to interpret due to previous bone infarcts. Localization of the infection focus is very important in choosing the aspiration site for bacteriologic studies. A negative study, however, should be interpreted cautiously

    2016-03-01

    A 4-year-old girl with history of acute myeloid leukemia post chemotherapy and stem cell transplant presented with pancytopenia. F-FDG PET-CT (PET-CT) showed multiple metastatic bone and extra medullary soft tissue lesions. Bone marrow biopsy after additional chemotherapy was negative. Concurrent FDG PET-CT demonstrated hypermetabolic foci in the left thigh and hand consistent with residual soft tissue disease. These lesions resolved after further treatment, but a subsequent PET-CT identified a new site of biopsy-proven chloroma. This case illustrates the important role of FDG PET-CT in identifying clinically undetectable extramedullary sites of disease, which may impact subsequent clinical management. PMID:26402136

    2014-08-01

    Full Text Available Acute lymphoblastic leukemia (ALL is curable in about 40-50% of adult patients, however this is subject to ample variations owing to several host- and disease-related prognostic characteristics. Currently, the study of minimal residual disease (MRD following induction and early consolidation therapy stands out as the most sensitive individual prognostic marker to define the risk of relapse following the achievement of remission, and ultimately that of treatment failure or success. Because substantial therapeutic advancement is now being achieved using intensified pediatric-type regimens, MRD analysis is especially useful to orientate stem cell transplantation choices. These strategic innovations are progressively leading to greater than 50% cure rates.

    Rhesus monkeys (Macaca mulatta) were infected subcutaneously with 1.0 x 10(4) to 1.5 x 10(4) metacyclic trypomastigotes of Trypanosoma cruzi (Colombian strain). Parasitological and immunological parameters were evaluated in these animals for periods of 1 month to over 3 years. A chagoma was observed between the 3rd and the 13th day after infection (a.i.) and patent parasitaemia between the 13th and 59th day a.i.. Thereafter, parasites were demonstrated only by haemoculture and/or xenodiagnosis. Circulating specific IgM and IgG antibodies were observed as early as in the 2nd week a.i. IgG levels persisted until the end of the experiment, but IgM antibodies were detectable nine months a.i. Haematological alterations comprised leucocytosis and lymphocytosis. Electrocardiographic alterations were minor and transient, similar to those observed in non-lethal human acute Chagas' myocarditis. Myocarditis and myositis, characterized by multiple foci of lympho-histiocyte inflammatory infiltrate, were present in monkeys sacrificed on the 41st, 70th and 76th day but not in the animal sacrificed 3 years and 3 months a. i.. The results suggest that Chagas' disease in rhesus monkeys reproduces the acute and indeterminate phases of human Chagas' disease. PMID:2128360

  4. A proposed emergency management program for acute care facilities in response to a highly virulent infectious disease.

    Petinaux, Bruno; Ferguson, Brandy; Walker, Milena; Lee, Yeo-Jin; Little, Gary; Parenti, David; Simon, Gary

    2016-01-01

    To address the organizational complexities associated with a highly virulent infectious disease (HVID) hazard, such as Ebola Virus Disease (EVD), an acute care facility should institute an emergency management program rooted in the fundamentals of mitigation, preparedness, response, and recovery. This program must address all known facets of the care of a patient with HVID, from unannounced arrival to discharge. The implementation of such a program not only serves to mitigate the risks from an unrecognized exposure but also serves to prepare the organization and its staff to provide for a safe response, and ensure a full recovery. Much of this program is based on education, training, and infection control measures along with resourcing for appropriate personal protective equipment which is instrumental in ensuring an organized and safe response of the acute care facility in the service to the community. This emergency management program approach can serve as a model in the care of not only current HVIDs such as EVD but also future presentations in our healthcare setting. PMID:26963227

  5. MRI findings of spine: acute flaccid paralysis associated with enterovirus 71 infected hand-foot-mouth disease

    Objective: To investigate the characteristics of spinal MR images in acute flaccid paralysis (AFP) associated with enterovirus 71 infected hand-foot-mouth disease. Methods: The spinal MR images of eight infants with AFP and positive EV71 cultures were analyzed during an outbreak of hand-foot-mouth disease in China in 2008. Results: Acute paralysis was observed in one lower limb in 4 of the 8 patients, in four limbs in 2 patients, in one upper limb and both lower limbs in 1 patient, 2 of the 8 patients also had brain stem encephalitis. Lesions were identified in anterior horn regions of spinal cord with hyperintensity on T2-weighted images and hypointensity on T1-weighted images. Location of the lesions included C3 to C7 (1 case), T10 extending to conus medullaris (5 cases) and a combination of the above (2 cases). Five of the 8 patients presented with unilateral paralysis. Two of the 5 cases showed unilateral hyperintense lesions in anterior horn regions and the remaining 3 cases showed bilateral hyperintense lesions in anterior horn regions with a unilateral predominance. One of the 3 patients with bilateral lesions showed slight enhancement of anterior horn with prominent enhancement of ventral roots after intravenous injections of contrast medium. Three of the 8 patients with bilateral paralysis showed bilateral hyperintensity in both anterior horn regions. Conclusion: MR is the imaging modality of choice for the detection of radiculomyelitis of AFP associated with EV71 infection. (authors)

  6. The Role of the Midmolecular Peptides in the Blood Cell Aggregation in Acute Periods of a Burn Disease

    Egorikhina M.N.

    2011-03-01

    Full Text Available The aim of the investigation is to study the effect of midmolecular peptide (MMP concentration on platelet and erythrocyte aggregation in severe burned patients. Materials and Methods. The investigation was carried out on 34 blood samples of healthy people and 30 blood samples of severe burned patients. There was determined the level of MMP, as well as that of creatinine, and urea. The “Amicon Ultra-4” microcentrifuge tubes were used to isolate MMP. Results. The level increase of average mass molecules isolated from the blood plasma of patients in an acute period of a burn disease has been stated to cause a progressive increase of platelet aggregation of healthy donors. The erythrocyte aggregation increase in such conditions is observed only in very high MMP concentrations. Creatinine and urea do not practically effect the ADP-induced platelet aggregation and the erythrocyte aggregation of healthy donors, and even decrease spontaneous thrombocyte aggregation in very high concentrations occur in an acute renal insufficiency. Conclusion. One of the reasons of platelet aggregation decrease under the influence of chemosorption in a burn disease can be the decrease of the MMP concentration in response to chemosorption.

    Acute Respiratory Distress Syndrome (ARDS) is a very severe syndrome leading to respiratory failure and subsequent mortality. Sepsis is one of the leading causes of ARDS. Thus, extracellular bacteria play an important role in the pathophysiology of ARDS. Overactivated neutrophils are the major effector cells in ARDS. Thus, extracellular bacteria triggered TH17-like innate immunity with neutrophil activation might accounts for the etiology of ARDS. Here, microarray analysis was employed to des...

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

    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.

  10. Luminal lactate in acute pancreatitis - validation and relation to disease severity

    Pynnönen Lauri

    2012-04-01

    Full Text Available Abstract Background Increased rectal luminal lactate concentration may be associated with the severity of the septic shock and high dose of vasopressors. It suggests hypoperfusion of the gut mucosa. This is potentially associated with bacterial translocation from the gut leading to local and systemic inflammation. In acute pancreatitis (AP bacterial translocation is considered as the key event leading to infection of necrotic pancreatic tissue and high severity of illness. Methods We used rectal luminal equilibration dialysis for the measurement of gut luminal lactate in 30 consecutive patients admitted to hospital due to acute pancreatitis to test the hypothesis that a single measurement of rectal luminal lactate predicts the severity of acute pancreatitis, the length of hospital stay, the need of intensive care and ultimately, mortality. We also tested the physiological validity of luminal lactate concentration by comparing it to luminal partial tension of oxygen. Additionally, a comparison between two different L-lactate analyzers was performed. Results High rectal luminal lactate was associated with low mucosal partial tension of oxygen (R = 0.57, p = 0.005 thereby indicating the physiological validity of the method. Rectal luminal lactate at the hospital admission was not associated with the first day or the highest SOFA score, CRP level, hospital length of stay, length of stay in intensive care or mortality. In this cohort of unselected consecutive patients with acute pancreatitis we observed a tendency of increased rectal lactate in the severe cases. Low precision and high bias was observed between two lactate analyzers. Conclusions The association between rectal luminal lactate and oxygen tension indicates that luminal lactate is a marker mucosal anaerobiosis.

    The most important congenital anomalies include pancreas divisum, annular pancreas and ectopic pancreas. Patients with pancreas divisum may be more susceptible to acute or chronic pancreatitis and patients with an annular pancreas may develop duodenal stenosis. In pancreas divisum the key finding is the visualization of the main duct draining into the duodenum via the small papilla, separated from the common bile duct. Annular pancreas may show as a well defined ring of pancreatic tissue that encircles the duodenum. Ectopic pancreas is usually asymptomatic but may give rise to abdominal complaints and may be confused with submucosal tumors. Acute pancreatitis is classified as mild or severe. In mild forms ultrasound is the imaging modality of choice whereas in severe forms with extensive pancreatic and peripancreatic necroses computed tomography is the favored method. It is crucial to identify signs and criteria that come along with an increased risk of infection of the necroses. MRI plays an inferior role in the assessment of acute pancreatitis. Chronic pancreatitis is a longstanding inflammatory and fibrosing process causing pain and loss of function. Cross-section imaging is particularly in demand for the detection of complications and the differentiation from pancreatic cancer. Autoimmune pancreatitis is a unique form of chronic pancreatitis characterized by lymphoplasmacytic infiltration and fibrosis, and favourable response to corticosteroid treatment. (orig.)

    AIM: To assess the role of the 13C-methacetin breath test (MBT) in patients with acute liver disease. METHODS: Fifteen patients with severe acute liver disease from diverse etiologies were followed-up with 13C-MBT during the acute phase of their illnesses (range 3-116 d after treatment). Patients fasted for 8 h and ingested 75 mg of methacetin prior to the MBT. We compared results from standard clinical assessment, serum liver enzymes, synthetic function, and breath test scores. RESULTS: Thirteen patients recovered and two patients died. In patients that recovered, MBT parameters improved in parallel with improvements in lab results. Evidence of consistent improvement began on day 3 for MBT parameters and between days 7 and 9 for blood tests. Later convergence to normality occurred at an average of 9 d for MBT parameters and from 13 to 28 d for blood tests. In both patients that died, MBT parameters remained low despite fluctuating laboratory values. CONCLUSION: The 13C-MBT provides a rapid, noninvasive assessment of liver function in acute severe liver disease of diverse etiologies. The results of this pilot clinical trial suggest that the MBT may offer greater sensitivity than standard clinical tests for managing patients with severe acute liver disease.

    The occurrence of minimal residual disease is an important prognostic factor under acute lymphoblastic leucosis in children and adults. In overwhelming majority of research studies bone marrow is used to detect minimal residual disease. The comparative characteristic of detection of minimal residual disease in peripheral blood and bone marrow was carried out. The prognostic role of occurrence of minimal residual disease in peripheral blood and bone marrow under therapy according protocol MLL-Baby was evaluated. The analysis embraced 142 pair samples from 53 patients with acute lymphoblastic leucosis and various displacements of gene MLL younger than 365 days. The minimal residual disease was detected by force of identification of chimeric transcripts using polymerase chain reaction in real-time mode in 7 sequential points of observation established by protocol of therapy. The comparability of results of qualitative detection of minimal residual disease in bone marrow and peripheral blood amounted to 84.5%. At that, in all 22 (15.5%) discordant samples minimal residual disease was detected only in bone marrow. Despite of high level of comparability of results of detection of minimal residual disease in peripheral blood and bone marrow the occurrence of minimal residual disease in peripheral blood at various stages of therapy demonstrated no independent prognostic significance. The established differences had no relationship with sensitivity of method determined by value of absolute expression of gene ABL. Most likely, these differences reflected real distribution of tumor cells. The results of study demonstrated that application of peripheral blood instead of bone marrow for monitoring of minimal residual disease under acute lymphoblastic leucosis in children of first year of life is inappropriate. At the same time, retention of minimal residual disease in TH4 in bone marrow was an independent and prognostic unfavorable factor under therapy of acute lymphoblastic

    Full Text Available Acute exacerbations are significant and frequent events in the natural history of chronic obstructive pulmonary disease. Majority of these exacerbations are of infectious aetiology, bacteria being responsible for 30-50% of these cases. With not many studies of similar type being conducted in the Indian context, this study was undertaken with the purpose of determining the bacteriology of acute exacerbations of chronic obstructive pulmonary disease in hospitalized patients with advanced disease and their antibiotic susceptibility pattern to formulate a cost effective algorithm for antibiotic usage while at the same time reducing the chances of emergence of drug resistance. Sputum sample from a total of 338 patients were send for Gram’s stain and culture sensitivity testing using an array of the commonly used antibiotics. Pathogenic bacteria were isolated from 203 (60.1% samples. Gram negative bacteria were isolated from 79.8 percent (162/203 cases while the rest were Gram positive. Klebsiella species were the commonest (49.2%; 100/203 Gram negative isolates from the sputum samples. Among the gram negative organisms, Carbapenem had the highest sensitivity (90.2% followed by Amikacin, Ciprofloxacin and Piperacillin-Tazobactam. Linezolid was found to be 100 percent sensitive amongst the Gram positive organisms while both Amoxicillin Clavulanate and Azithromycin showed a rather low sensitivity profile overall. 5.0 percent of the Klebsiella infections were multi drug resistant. It was thereby concluded that either Amikacin, Ciprofloxacin or Piperacillin-Tazobactam for be considered for Gram negative organisms and Linezolid be considered for Gram positive organisms as first line antibiotics in empirical therapy while Carbapenems may be kept as reserve drugs should the first line drugs fail.

  15. Comparison between qualitative and real-time polymerase chain reaction to evaluate minimal residual disease in children with acute lymphoblastic leukemia

    2015-12-01

    Full Text Available ABSTRACT Introduction: Minimal residual disease is an important independent prognostic factor that can identify poor responders among patients with acute lymphoblastic leukemia. Objective: The aim of this study was to analyze minimal residual disease using immunoglobulin (Ig and T-cell receptor (TCR gene rearrangements by conventional polymerase chain reaction followed by homo-heteroduplex analysis and to compare this with real-time polymerase chain reaction at the end of the induction period in children with acute lymphoblastic leukemia. Methods: Seventy-four patients diagnosed with acute lymphoblastic leukemia were enrolled. Minimal residual disease was evaluated by qualitative polymerase chain reaction in 57 and by both tests in 44. The Kaplan-Meier and multivariate Cox methods and the log-rank test were used for statistical analysis. Results: Nine patients (15.8% were positive for minimal residual disease by qualitative polymerase chain reaction and 11 (25% by real-time polymerase chain reaction considering a cut-off point of 1 × 10−3 for precursor B-cell acute lymphoblastic leukemia and 1 × 10−2 for T-cell acute lymphoblastic leukemia. Using the qualitative method, the 3.5-year leukemia- free survival was significantly higher in children negative for minimal residual disease compared to those with positive results (84.1% ± 5.6% versus 41.7% ± 17.3%, respectively; p-value = 0.004. There was no significant association between leukemia-free survival and minimal residual disease by real-time polymerase chain reaction. Minimal residual disease by qualitative polymerase chain reaction was the only variable significantly correlated to leukemia-free survival. Conclusion: Given the difficulties in the implementation of minimal residual disease monitoring by real-time polymerase chain reaction in most treatment centers in Brazil, the qualitative polymerase chain reaction strategy may be a cost-effective alternative.

    2015-01-01

    Full Text Available We tested the hypothesis that acute post-exercise change in blood pressure (BP may predict exercise training responses in BP in patients with coronary artery disease (CAD. Patients with CAD (n=116, age 62±5 years, 85 men underwent BP assessments at rest and during 10-min recovery following a symptom-limited exercise test before and after the 6-month training intervention (one strength and 3-4 aerobic moderate-intensity exercises weekly. Post-exercise change in systolic BP (SBP was calculated by subtracting resting SBP from lowest post-exercise SBP. The training-induced change in resting SBP was -2±13 mmHg (p=0.064, ranging from -42 to 35 mmHg. Larger post-exercise decrease in SBP and baseline resting SBP predicted a larger training-induced decrement in SBP (β=0.46 and β=-0.44, respectively, p<0.001 for both. Acute post-exercise decrease in SBP provided additive value to baseline resting SBP in the prediction of training-induced change in resting SBP (R squared from 0.20 to 0.26, p=0.002. After further adjustments for other potential confounders (sex, age, baseline body mass index, realized training load, post-exercise decrease in SBP still predicted the training response in resting SBP (β=0.26, p=0.015. Acute post-exercise change in SBP was associated with training-induced change in resting SBP in patients with CAD, providing significant predictive information beyond baseline resting SBP.

    2016-01-01

    Cardiovascular diseases are one of the leading causes of morbidity and mortality. In recent researches, it is demonstrated that microRNAs (miRNAs) are expressed exten-sively in cardiovascular system and regulate gene expression in various cardiovascular diseases. Here, we are giving overview on number of miRNAs involved in patho-physiology of various cardiovascular diseases, and diagnostic and therapeutic potentials of miRNAs in these diseases. MiRNAs are a group of small non-coding mRNAs with approximately 18–22 nucleotides in length that regulate gene expression post tran-scriptionally. MiRNAs are regulated in various cardiovascular diseases like hyperten-sion, congestive heart failure, congenital heart defects, coronary artery disease and stroke. Some of these miRNAs also act as potential biomarker of these cardiovascular diseases. Inhibition of these miRNAs via different approaches like chemically modified antisense oligonucleotide, antagomirs, and locked nucleic acids serves as effective approaches for inactivating pathological miRNAs. Clinical trials are being conducted on therapeutic and diagnostic potentials of miRNAs. However, extensive researches are required to explore the therapeutic and diagnostic values of miRNAs as successful as classical approaches.

  2. Acute Radiation Disease : Cutaneous Syndrome and Toxic properties of Radiomimetics -Radiation Neurotoxins and Hematotoxins.

    Popov, Dmitri; Maliev, Slava

    Cutaneous injury is an important complication of a general or local acute irradiation. A type of a skin and tissues lesions depends on a type, intensity, and period of irradiation. Also, the clinical picture, signs, and manifestations of the cutaneous syndrome depend on a type of the radiation toxins circulated in lymph and blood of irradiated mammals. Radiation Toxins were isolated from lymph of the mammals that were irradiated and developed different forms of the Acute Radiation Syndromes (ARS) -Cerebrovascular, Cardiovascular, Gastrointestinal, and Hematopoietic. Radiation Toxins can be divided into the two important types of toxins (Neu-rotoxins and Hematotoxins) or four groups. The effects of Radiation Neurotoxins include severe damages and cell death of brain, heart, gastrointestinal tissues and endothelial cells of blood and lymphatic vessels. The hematotoxicity of Hematotoxic Radiation Toxins includes lym-phopenia, leukopenia, thrombocytopenia, and anemia in the blood circulation and transitory lymphocytosis and leukocytosis in the Central Lymphatic System. In all cases, administration of the Radiomimetics (Radiation Toxins) intramuscularly or intravenously to healthy, radiation naive mammals had induced and developed the typical clinical manifestations of the ARS. In all cases, administration of Radiomimetics by subtoxic doses had demonstrated development of typical clinical signs of the cutaneous syndrome such as hair loss, erythema, swelling, desqua-mation, blistering and skin necrosis. In animal-toxic models, we have activated development of the local skin and tissue injury after injection of Radiation Toxins with cytoxic properties.

    Objective:To explore socio-demographic data of the population as proxies for risk factors in disease transmission modeling at different geographic scales. Methods: Patient records of confirmed H1N1 influenza were analyzed at three geographic aggregation levels together with population census statistics. Results:The study confirmed that four population factors were related in different degrees to disease incidence, but the results varied according to spatial resolution. The degree of association actually decreased when data of a higher spatial resolution were used. Conclusions:We concluded that variables at suitable spatial resolution may be useful in improving the predictive powers of models for disease outbreaks.

    2015-01-01

    The aim of our study was to determine whether the use of CT scanning in the assessment of acute diverticulitis can be reduced without a negative effect on outcome. Our series consisted of 93 out of 100 patients with acute diverticulitis admitted to the Emergency Room of our institution in the period from February 2012 to March 2013.The Hinchey classification system was used to stage disease based on findings on ultrasound (US) examination and/or computed tomography (CT) scanning. We compared the patients' Hinchey stage (HS) on admission and 72 hours later. Types of treatment were defined as emergency or delayed intervention (operative approaches (OA); ultrasound-guided percutaneous drainage (UPD), and surgery. The borderline between conservative and surgical management was identified. In patients with a HS sufficient and they can be spared the exposure to ionizing radiation associated with CT scans. The skill of the individual operator in US examination was found to be of key importance. As regards CT scanning, we found, in agreement with the literature, that it has greater specificity and sensitivity than US, and is therefore indicated if the patient's condition has deteriorated.

    Full Text Available Objective. To evaluate the efficacy and safety of Weijing decoction combined with routine pharmacotherapy (RP for the treatment of acute exacerbations of chronic obstructive pulmonary disease (AECOPD. Methods. Randomized controlled trials (RCT evaluating Weijing decoction for AECOPD were included. English, Chinese, and Japanese databases were searched from their respective inceptions to June 2013. The methodological quality was assessed according to the Cochrane Collaboration’s risk of bias tool. All data were analyzed and synthesized using RevMan 5.2 software. Results. Fifteen (15 studies involving 986 participants were included. Participants were diagnosed with COPD in the acute exacerbation stage. In addition, most of studies reported that they included participants with the Chinese medicine syndrome, phlegm-heat obstructing the Lung. Weijing decoction combined with RP improved lung function (forced expiratory volume in one second; FEV1, arterial blood gases (PaO2 and PaCO2, clinical effective rate, and reduced inflammatory biomarkers (TNF-α and IL-8 when compared with RP alone. No severe adverse events were reported in these studies. Conclusions. Weijing decoction appeared to be beneficial for AECOPD and well-tolerated when taken concurrently with RP, such as antibiotics, bronchodilators (oral and inhaled, and mucolytics.

    As relapses are common in acute myeloid leukemia (AML), early relapse prediction is of high importance. Although conventional minimal residual disease (MRD) measurement is carried out in bone marrow (BM), peripheral blood (PB) would be an advantageous alternative source. This study aims to investigate the specificity of leukemia-associated immunophenotypes used for MRD detection in blood samples. Consistency of PB MRD as compared with BM MRD was determined in flow cytometric data of 205 paired BM and PB samples of 114 AML patients. A significant correlation was found between PB and BM MRD (r=0.67, Pconsolidation therapy. As PB MRD appeared to be an independent predictor for response duration, the highly specific PB MRD assay may have a prominent role in future MRD assessment in AML. PMID:26373238

    Wang Ying

    2012-08-01

    Full Text Available Abstract Background The design of new interventions to improve health care for patients with chronic obstructive pulmonary disease (COPD requires knowledge about what patients with an acute exacerbation experience as important and useful. The objective of the study was to explore patients’ experiences of an early discharge hospital at home (HaH treatment programme for exacerbations in COPD. Methods Six exacerbated COPD patients that were randomised to receiving HaH care and three patients randomised to receiving traditional hospital care were interviewed in semi-structured in-depth interviews. Four spouses were present during the respective patients’ interviews. The interviews were audio-taped, transcribed and analysed by a four-step method for systematic text condensing. Results Despite limited assistance from the health care service, the patients and their spouses experienced the HaH treatment as safe. They expressed that information that was adapted to specific situations in their daily lives and given in a familiar environment had positive impact on their self-management of COPD. Conclusion The results contribute to increased knowledge and awareness about what the patients experienced as important aspects of a HaH treatment programme. How adapted input from health services can make patients with exacerbation of COPD feel safe and better able to manage their disease, is important knowledge for developing new and effective health services for patients with chronic disease.

  13. The Role of Biomarkers in the Diagnosis and Risk Stratification of Acute Graft-versus-Host Disease: A Systematic Review.

    Ali, Alaa M; DiPersio, John F; Schroeder, Mark A

    2016-09-01

    Allogeneic hematopoietic cell transplantation (HCT) is an increasingly used curative modality for hematologic malignancies and other benign conditions. Attempts to reduce morbidity and mortality and improve survival in patients undergoing HCT are crucial. The ability to diagnose acute graft-versus-host disease (aGVHD) in a timely manner, or to even predict aGVHD before clinical manifestations, along with the accurate stratification of these patients, are critical steps to improve the treatment and outcomes of these patients. Many novel biomarkers that may help achieve these goals have been studied recently. This overview is intended to assist clinicians and investigators by providing a comprehensive review and analytical interpretation of the current knowledge concerning aGVHD and biomarkers likely to prove useful in diagnosis and risk stratification of this condition, along with the difficulties that hamper this approach.

    2016-03-01

    Methotrexate is being used for many years in the treatment of chronic medical disorders e.g. rheumatoid arthritis since 1951. It has been associated with various systemic toxicities and complications including bone marrow suppression and lymphomas. The development of leukaemia in a patient of chronic rheumatoid arthritis is either related with the primary disease or due to the drugs which are used in the treatment like cyclophosphamide. In our present case, a 70-year-old female who was a known case of Rheumatoid Arthritis (RA) and was on methotrexate once a week orally for the past 20 years presented with complaints of loss of appetite, loss of weight and anaemia since 2 months. After thorough examination and investigation, she was diagnosed with acute myeloid leukaemia (AML-M4) with bilateral chest consolidation. PMID:27134915

    2016-01-01

    The clinical utility of minimal residual disease (MRD) analysis in acute myeloid leukaemia (AML) is not yet defined. We analysed the prognostic impact of MRD level at complete remision after induction therapy using multiparameter flow cytometry in 306 non-APL AML patients. First, we validated the prognostic value of MRD-thresholds we have previously proposed (≥ 0.1%; ≥ 0.01-0.1%; and information on favourable and adverse cytogenetics, since patients with favourable cytogenetics and high MRD levels have poor prognosis and patients with adverse cytogenetics but undetectable MRD overcomes the adverse prognosis. Interestingly, in patients with intermediate or high MRD levels, intensification with transplant improved the outcome as compared with chemotherapy, while the type of intensification therapy did not influenced the outcome of patients with low MRD levels. Multivariate analysis revealed age, MRD and cytogenetics as independent variables. Moreover, a scoring system, easy in clinical practice, was generated based on MRD level and cytogenetics.

    Respiratory infections constitute the most widespread human infectious disease, and a substantial proportion of them are caused by unknown etiological agents. Reoviruses (respiratory enteric orphan viruses) were first isolated from humans in the early 1950s and so named because they were not associated with any known disease. Here, we report a previously unknown reovirus (named “Melaka virus”) isolated from a 39-year-old male patient in Melaka, Malaysia, who was suffering from high fever and ...

    2004-01-01

    Background Immunostimulating agents made from bacterial extracts represent a class of medications that contains antigens derived from several bacterial strains and their potential ability to prevent bacterial infections results from the stimulation of the nonspecific component of the immune system. The present study investigated the effect of the oral immunostimulant Broncho-Vaxom, which includes material from eight different species of bacteria that are frequently present in the lower respiratory tract, on the frequency and severity of acute exacerbation in patients with chronic bronchitis accompanied by chronic obstructive pulmonary disease (COPD). Methods Ninety patients with chronic bronchitis complicated with COPD were randomly divided into groups A and B. Forty-nine subjects in group A received oral capsules containing 7mg Broncho-Vaxom, while 41 patients in group B received similar placebo capsules. Both groups took one capsule daily for the first 10 days of each month for 3 consecutive months. The frequency of acute exacerbation, symptom scores, and lung function were recorded for the following one year period.Results There was a significant decrease in the incidence, duration, and severity of acute exacerbation, as well as a reduction in the course of antibiotics administered and in the dosage of bronchodilator and mucolytic agent in group A, as compared to group B (P<0.05, respectively). Symptom scores for cough, sputum, dyspnea, as well as symptoms observed upon auscultation of the chest also improved significantly in group A as compared to group B (P<0.05, respectively). The bacterial clearance rate in sputum cultures from patients who received no antibiotics for the first 3 months was also significantly higher in group A compared to group B (P<0.01).Conclusions Orally administered Broncho-Vaxom is associated with a decrease in the incidence of acute exacerbation and a decrease in the need for antibiotics and symptomatic relief medications in patients

The total cross-sectional area (CSA of small pulmonary vessels has been reported to correlate with the pulmonary artery pressure, and this technique has enabled the assessment of pulmonary vascular involvements. We investigated the contribution of morphological alterations in the pulmonary vessels to severe acute exacerbation of COPD (AE-COPD.Methods: This study enrolled 81 patients with COPD and 28 non-COPD subjects as control and assessed the percentage of CSA (%CSA less than 5 mm2 (%CSA<5 and %CSA in the range of 5–10 mm2 (%CSA5–10 on high-resolution computed tomography images.Results: Compared with the non-COPD subjects, the COPD patients had lower %CSA<5. %CSA<5 was positively correlated with airflow limitation and negatively correlated with the extent of emphysema. COPD patients with lower %CSA<5 showed significantly increased incidences of severe AE-COPD (Gray’s test; P=0.011. Furthermore, lower %CSA<5 was significantly associated with severe AE-COPD (hazard ratio, 2.668; 95% confidence interval, 1.225–5.636; P=0.010.Conclusion: %CSA<5 was associated with an increased risk of severe AE-COPD. The distal pruning of the small pulmonary vessels is a part of the risk associated with AE-COPD, and %CSA<5 might be a surrogate marker for predicting AE-COPD.

    Human rhinoviruses (HRVs) were historically considered upper airway pathogens. However, they have recently been proven to cause infections in the lower respiratory tract, resulting in hospitalization of children with pneumonia, bronchiolitis, and chronic pulmonary obstruction. In this report, HRV frequency and seasonality are described together with patient clinical-epidemiological aspects. From a total of 452 surveyed samples, the HRV nucleic acids was detected in 172 (38.1%) and found in every month of the study year. 60% of inpatients with acute respiratory infection (ARI) associated with HRV were under 6 months of age and 31% had a clinical history, being preterm birth and recurrent wheezing the prevailing conditions. The most frequent discharge diagnoses were pneumonia (35.2%), bronchiolitis (32.4%), and bronchitis (12.4%). Fifteen point nine percent of patients required admission into intensive care units. The results obtained in this study demonstrated the association between HRV and children hospitalizations caused by ARI. PMID:25983014

In this study we analyze all cases reported in a retrospective analysis over a 2-year period to define risk factors, clinical presentation, endoscopic features, histological appearance, treatment and outcome. Our department has recorded 7 cases from 6,003 endoscopies performed in the last 2 years. The finding of a "black esophagus" represented 0.11% of cases.

  5. Acute Pancreatitis Induced by Azathioprine and 6-mercaptopurine Proven by Single and Low Dose Challenge Testing in a Child with Crohn Disease.

    Yi, Geum-Chae-Won; Yoon, Ka-Hyun; Hwang, Jin-Bok

    2012-12-01

    We report here a case of drug-induced acute pancreatitis proved by elimination and single, low dose challenge test in a child with Crohn disease. A 14-year-old boy with moderate/severe Crohn disease was admitted due to high fever and severe epigastric pain during administration of mesalazine and azathioprine. Blood test and abdominal ultrasonography revealed acute pancreatitis. After discontinuance of the medication and supportive care, the symptoms and laboratory findings improved. A single, low dose challenge test was done to confirm the relationship of the adverse drug reaction and acute pancreatitis, and to discriminate the responsible drug. Azathioprine and 6-mercaptopurine showed positive responses, and mesalazine showed a negative response. We introduce the method of single, low dose challenge test and its interpretation for drug-induced pancreatitis. PMID:24010098

    2016-07-01

    The disease profile in the Indian population provides a unique opportunity for studying the host microbiome interaction in both infectious (amebiasis) and autoimmune diseases like inflammatory bowel disease (IBD) from a similar environment and genetic background. Analysis of fecal samples from untreated amebic liver abscess (ALA) patients, Entamoeba histolytica (Eh)-negative and -positive asymptomatic individuals, and pus samples from naive ALA patients revealed a significant reduction in Lactobacillus in asymptomatic individuals (Eh +ve) and ALA patients. Two anaerobic genera, namely Bacteroides and Peptostreptococcus, were detected in naive ALA pus samples. Analysis of fecal samples from amoebic colitis patients showed a significant decline in population of Bacteroides, Clostridium coccoides and leptum subgroup, Lactobacillus, Campylobacter, and Eubacterium, whereas a significant increase in Bifidobacterium was observed. Mucosa-associated bacterial flora analysis from IBD patients and healthy controls revealed a significant difference in concentration of bacteria among predominating and subdominating genera between ulcerative colitis (UC), Crohn's disease (CD) patients, and controls. In contrast to the mucosal studies, we found a significant increase in lactobacilli population in fecal samples of active UC patients. Another study revealed a significant decrease of Clostridium coccoides and leptum clusters in fecal samples of active UC patients along with decreased concentrations of fecal SCFAs, especially of n-butyrate, iso-butyrate, and acetate. We therefore found similar perturbations in gut microbiome in both infectious and autoimmune diseases, indicating inflammation to be the major driver for changes in gut microbiome. PMID:26994772

  17. Trypanosoma cruzi IV causing outbreaks of acute Chagas disease and infections by different haplotypes in the Western Brazilian Amazonia.

    Wuelton Marcelo Monteiro

    Full Text Available BACKGROUND: Chagas disease is an emergent tropical disease in the Brazilian Amazon Region, with an increasing number of cases in recent decades. In this region, the sylvatic cycle of Trypanosoma cruzi transmission, which constitutes a reservoir of parasites that might be associated with specific molecular, epidemiological and clinical traits, has been little explored. The objective of this work is to genetically characterize stocks of T. cruzi from human cases, triatomines and reservoir mammals in the State of Amazonas, in the Western Brazilian Amazon. METHODOLOGY/PRINCIPAL FINDINGS: We analyzed 96 T. cruzi samples from four municipalities in distant locations of the State of Amazonas. Molecular characterization of isolated parasites from cultures in LIT medium or directly from vectors or whole human blood was performed by PCR of the non-transcribed spacer of the mini-exon and of the 24 S alfa ribosomal RNA gene, RFLP and sequencing of the mitochondrial cytochrome c oxidase subunit II (COII gene, and by sequencing of the glucose-phosphate isomerase gene. The T. cruzi parasites from two outbreaks of acute disease were all typed as TcIV. One of the outbreaks was triggered by several haplotypes of the same DTU. TcIV also occurred in isolated cases and in Rhodnius robustus. Incongruence between mitochondrial and nuclear phylogenies is likely to be indicative of historical genetic exchange events resulting in mitochondrial introgression between TcIII and TcIV DTUs from Western Brazilian Amazon. TcI predominated among triatomines and was the unique DTU infecting marsupials. CONCLUSION/SIGNIFICANCE: DTU TcIV, rarely associated with human Chagas disease in other areas of the Amazon basin, is the major strain responsible for the human infections in the Western Brazilian Amazon, occurring in outbreaks as single or mixed infections by different haplotypes.

  18. PPARγ activation normalizes resolution of acute sterile inflammation in murine chronic granulomatous disease

    Fernandez-Boyanapalli, Ruby; Frasch, S. Courtney; Riches, David W.H.; Vandivier, R. William; Henson, Peter M.; Bratton, Donna L.

    2010-01-01

    Absence of a functional nicotinamide adenine dinucleotide phosphate (NADPH) oxidase predisposes chronic granulomatous disease (CGD) patients to infection, and also to unexplained, exaggerated inflammation. The impaired recognition and removal (efferocytosis) of apoptotic neutrophils by CGD macrophages may contribute to this effect. We hypothesized that peroxisome proliferator-activated receptor γ (PPARγ) activation during CGD inflammation is deficient, leading to altered macrophage programmin...

  4. Changes in the mitochondrial antioxidant systems in neurodegenerative diseases and acute brain disorders.

    Ruszkiewicz, Joanna; Albrecht, Jan

    2015-09-01

    Oxidative and nitrosative stress (ONS) contributes to the pathogenesis of most brain maladies, and the magnitude of ONS is related to the ability of cellular antioxidants to neutralize the accumulating reactive oxygen and nitrogen species (ROS/RNS). While the major ROS/RNS scavengers and regenerators of bio-oxidized molecules, superoxide dysmutases (SODs), glutathione (GSH), thioredoxin (Trx) and peroxiredoxin (Prx), are distributed in all cellular compartments. This review specifically focuses on the role of the systems operating in mitochondria. There is a growing consensus that the mitochondrial SOD isoform - SOD2 and GSH are critical for the cellular antioxidant defense. Variable changes of the expression or activities of one or more of the mitochondrial antioxidant systems have been documented in the brains derived from human patients and/or in animal models of neurodegenerative diseases (Alzheimer's disease, Parkinson's disease), cerebral ischemia, toxic brain cell damage associated with overexposure to mercury or excitotoxins, or hepatic encephalopathy. In many cases, ambiguity of the responses of the different antioxidant systems in one and the same disease needs to be more conclusively evaluated before the balance of the changes is viewed as beneficial or detrimental. Modulation of the mitochondrial antioxidant systems may in the future become a target of antioxidant therapy. PMID:25576182

  5. Immunosuppression during acute infection with foot-and-mouth disease virus in swine is mediated by IL-10.

    Fayna Díaz-San Segundo

    Full Text Available Foot-and-mouth disease virus (FMDV is one of the most contagious animal viruses, causing a devastating disease in cloven-hoofed animals with enormous economic consequences. Identification of the different parameters involved in the immune response elicited against FMDV remains unclear, and it is fundamental the understanding of such parameters before effective control measures can be put in place. In the present study, we show that interleukin-10 (IL-10 production by dendritic cells (DCs is drastically increased during acute infection with FMDV in swine. In vitro blockade of IL-10 with a neutralizing antibody against porcine IL-10 restores T cell activation by DCs. Additionally, we describe that FMDV infects DC precursors and interferes with DC maturation and antigen presentation capacity. Thus, we propose a new mechanism of virus immunity in which a non-persistent virus, FMDV, induces immunosuppression by an increment in the production of IL-10, which in turn, reduces T cell function. This reduction of T cell activity may result in a more potent induction of neutralizing antibody responses, clearing the viral infection.

  6. The epidemiology of acute viral gastroenteritis in hospitalized children in Cordoba city, Argentina: an insight of disease burden

    GIORDANO Miguel O.

    2001-01-01

    Full Text Available Information concerning the disease burden of viral gastroenteritis has important implications for the use and monitoring the impact of public health policies. The present study, carried out in Córdoba city, Argentina, documents the epidemiology of severe viral diarrhea as well as the burden of viral gastrointestinal disease in the hospital children admission. A total of 133 stools were collected from hospitalized children (Town Childhood Hospital suffering from acute diarrhea and studied for the presence of Group A rotavirus, astrovirus and adenovirus 40/41 by enzyme-immuno assay, between November 1997 and October 1998. Enteric viruses accounted for 42.1% of the total diarrheal cases analyzed. Group A rotaviruses, astroviruses, adenoviruses 40/41 and mixed infections were found in 35.3, 4.5, 1.5, and 0.8% studied specimens respectively. We estimated that 1 in 27 children in the 0-35 month-old cohort/range would be annually hospitalized for a viral gastroenteritis illness. The major impact on viral diarrhea lies on rotaviral infection, accouting for 84.0% of the viral diarrheal cases analyzed and for approximately one third of severe diarrheas requiring hospital admission in Córdoba City, Argentina.

  7. [Acute ischemic spinal cord disease. Spinal cord infarction. A clinical study and MRI in 8 cases].

    Pau Serradell, A

    1994-01-01

    Acute spinal cord infarction (ASCI) occurs infrequently and may have diverse causes. The diagnosis of ASCI, and particularly of an anterior spinal artery syndrome (ASAS) can be confirmed nowadays by MRI, whereas in the past only necropsy confirmation was possible. Pathophysiology and long-term prognosis may be better known at present and treatments more consistent. We present the longitudinal study and clinical features of 8 patients suffering from ASCI. All of them were personally studied and had MRI examinations, often with sequential studies. three groups must be considered: one included 4 cases of ASAS at cervical level, the second 2 cases of ASAS at thoracic level and the third group with infarction of the conus medullaris (ICM), one of them developed during surgical repair of an infrarenal aortic aneurysm. Motor and sensory sequelae were assessed in each case together with possible etiological factors. In conclusion, recovery after ASAS tends to be dependent on the severity of the initial deficit. At cervical level, clinical and morphological findings argue in favour of an extrinsic selective compression of the C7 right radiculo-medullary artery as responsible for the ASA. At thoracic level, the artery preferentially occluded seems to be the sulco-commisural artery as a consequence of disc compression. Finally, an underlying peculiarity of the pattern of arterial supply is a probable predisposing factor for ICM. Generally, the long-term prognosis of ASCI is not necessarily bad. PMID:7801036

    Harini Chowdary Vadlamudi; Prasanna Raju Yalavarthi; Jyotsna Thanniru; Vandana KR; Sundaresan CR

    2016-01-01

    Objective: To design solid self-microemulsifying drug delivery system (S-SMEDDS) of entacapone and evaluate for its anti-Parkinson's potentials. Methods: Solubility studies were performed in various vehicles i.e., oils, surfactants and co-surfactants and pseudo-ternary phase diagrams were plotted to understand the microemulsion formation region. Liquid self-microemulsifying drug delivery systems (SMEDDS) were developed using gingelly and rice bran oil as lipid vehicles, Tween 80 and Span 20 as surfactants and glycerin, propylene glycol as co-surfactants. They were characterized by Fourier transform infrared spectroscopy, pH, viscosity, zeta potential, polydispersibility index and droplet size analysis and evaluated for drug content, in-vitro release, in-vitro diffusion and ex-vivo permeation. Optimized liquid SMEDDS were converted into S-SMEDDS by adsorption and melt granulation procedures. Character-ization by differential scanning calorimetry, SEM, micrometrics, reconstitution property, moisture content and evaluation by drug content, drug release kinetics and shelf-life were performed for S-SMEDDS. Parkinsonism was induced and pharmacodynamic potentials of S-SMEDDS were evaluated. Results: S-SMEDDS formulation AG8 had shown the highest drug release of 90.92%within 60 min. Pharmacodynamic studies also proved the efficiency of entacapone S-SMEDDS against Parkinsonism. Conclusions: Entacapone S-SMEDDS is an effective drug delivery system that offers more predictable and extensive drug release with enhanced shelf-life in the treatment of acute Parkinsonism.

    2005-05-01

    Outdoor carbon monoxide comes mainly from vehicular emissions, and high concentrations occur in areas with heavy traffic congestion. CO binds to hemoglobin, forming carboxyhemoglobin (COHb), and reduces oxygen delivery. We investigated the link between the adverse effects of CO on the respiratory system using COHb as a marker for chronic CO exposure. We examined the relationship between acute respiratory infections (ARIs) and COHb concentrations in school-age children living in urban and suburban areas of Quito, Ecuador. We selected three schools located in areas with different traffic intensities and enrolled 960 children. To adjust for potential confounders we conducted a detailed survey. In a random subsample of 295 children, we determined that average COHb concentrations were significantly higher in children attending schools in areas with high and moderate traffic, compared with the low-traffic area. The percentage of children with COHb concentrations above the safe level of 2.5% were 1, 43, and 92% in low-, moderate-, and high-traffic areas, respectively. Children with COHb above the safe level are 3.25 [95% confidence interval (CI), 1.65-6.38] times more likely to have ARI than children with COHb < 2.5%. Furthermore, with each percent increase in COHb above the safety level, children are 1.15 (95% CI, 1.03-1.28) times more likely to have an additional case of ARI. Our findings provide strong evidence of the relation between CO exposure and susceptibility to respiratory infections. PMID:15866771

    The current lack of effective therapeutics for patients with acute kidney injury (AKI) represents an important and unmet medical need. Given the importance of the clinical problem, it is time for us to take a few steps back and reexamine current practices. The focus of this review is to explore the extent to which failure of therapeutic translation from animal studies to human studies stems from deficiencies in the preclinical models of AKI. We will evaluate whether the preclinical models of AKI that are commonly used recapitulate the known pathophysiologies of AKI that are being modeled in humans, focusing on four common scenarios that are studied in clinical therapeutic intervention trials: cardiac surgery-induced AKI; contrast-induced AKI; cisplatin-induced AKI; and sepsis associated AKI. Based on our observations, we have identified a number of common limitations in current preclinical modeling of AKI that could be addressed. In the long term, we suggest that progress in developing better preclinical models of AKI will depend on developing a better understanding of human AKI. To this this end, we suggest that there is a need to develop greater in-depth molecular analyses of kidney biopsy tissues coupled with improved clinical and molecular classification of patients with AKI.

  11. Comparison of the TIMI and the GRACE risk scores with the extent of coronary artery disease in patients with non-ST-elevation acute coronary syndrome

    Objective: To compare the accuracy of the Global Registry of Acute Coronary Events risk score and the Thrombolysis In Myocardial Infarction risk score in predicting the extent of coronary artery disease in patients with non-ST segment elevation acute coronary syndrome. Methods: The cross-sectional study comprising 406 consecutive patients was conducted at the National Institute of Cardiovascular Diseases, Karachi, from August 2010 to March 2011. For all patients, the GRACE and TIMI RS's relevant scores on the two indices were calculated on admission using specified variables. The patients underwent coronary angiography to determine the extent of the disease. A significant level was defined as >70% stenosis in any major epicardial artery or >50% stenosis in the left main coronary artery. SPSS 19 was used for statistical analysis. Results: Both the indices showed good predictive value in identifying the extent of the disease. A Thrombolysis In Myocardial Infarction score >4 and Global Registry of Acute Coronary Events score >133 was significantly associated with 3vessel disease and left main disease, while for the former score <4 and latter score <133 was associated with normal or non-obstructive coronary disease (p<0.01). On comparison of the two risk scores, the discriminatory accuracy of the latter was significantly superior to the former in predicting 2vessel, 3vessel and left main diseases (p<0.05). Conclusion: Although both the indices were helpful in predicting the extent of the disease, the Global Registry showed better performance and was more strongly associated with multi-vessel and left main coronary artery disease.

    Household contacts (HCs) of patients with tuberculosis (TB) are at higher risk of infection as well as the development of active disease. Longitudinal tracking of antigen-specific cytokines after acute exposure may significantly advance our understanding of the dynamic changes in cytokine patterns associated with disease establishment. To achieve this objective, we carried out a prospective cohort study with healthy HCs after exposure to TB. The patterns of cytokines (gamma interferon [IFN-gamma] and interleukin 10 [IL-10]) in response to mycobacterial antigens (culture filtrate [CF] proteins) and nonspecific mitogens (phytohemagglutinin [PHA] and lipopolysaccharide [LPS]) were assessed at 0, 6, 12, and 24 months after exposure. Seven of 109 (6.4%) HCs developed active disease. Six of the seven individuals were females, and active disease developed between 12 and 15 months after exposure in 5/20 families. The most significant findings were the exponential increases ( approximately 1,000-fold) in both the CF protein- and the PHA- or LPS-induced IFN-gamma/IL-10 ratio in healthy HCs (n = 26), which peaked at 12 months, compared to the levels in HCs who developed disease (n = 7), in whom relatively flat responses were observed during the 24-month period. Linear trends for 0 to 12 and 0 to 24 months for the CF protein-induced IFN-gamma/IL-10 ratio showed significant differences between the two groups, as determined by the use of the Mantel extension test for chi(2) analysis (odds ratio = 0.45; 95% confidence interval = 0.295 to 0.685; P = 0.0002). Our results strongly suggest that the magnitude of the IFN-gamma/IL-10 ratio at 12 months after exposure may be a critical determinant in the resolution of infection. These studies provide new insights into the cytokine responses associated with disease establishment or the resolution of infection after natural exposure to TB and have implications for TB control programs as well vaccine efficacy studies.

    Marchiafava-Bignami disease (MBD) is a rare toxic disorder strongly associated with chronic alcoholism. It is characterized by progressive demyelination and necrosis of the corpus callosum. The process may extend to neighboring white matter and subcortical regions. We report a case of MBD in which fluid-attenuated inversion recovery and diffusion-weighted imaging revealed symmetrical hyperintense lesions with diffuse involvement of the corpus callosum, white matter, corticospinal tract, internal capsule, and middle cerebellar peduncle.

    Alcohol-induced liver damage is a major burden for most societies, and murine studies can provide a means to better understand its pathogenesis and test new therapies. However, there are many models reported with widely differing phenotypes, not all of which fully regenerate the spectrum of human disease. Thus, it is important to understand the implications of these variations to efficiently model human disease. This review critically appraises key articles in the field, detailing the spectrum of liver damage seen in different models, and how they relate to the phenotype of disease seen in patients. A range of different methods of alcohol administration have been studied, ranging from ad libitum consumption of alcohol and water to modified diets (eg, Lieber deCarli liquid diet). Other feeding regimens have taken more invasive routes using intragastric feeding tubes to infuse alcohol directly into the stomach. Notably, models using wild-type mice generally produce a milder phenotype of liver damage than those using genetically modified mice, with the exception of the chronic binge-feeding model. We recommend panels of tests for consideration to standardize end points for the evaluation of the severity of liver damage-key for comparison of models of injury, testing of new therapies, and subsequent translation of findings into clinical practice.

    2012-01-01

    Full Text Available Background: Acute exacerbations of chronic obstructive pulmonary disease (AeCOPD are important causes of morbidity and mortality. In this study, we analyzed procalcitonin (PCT levels in AeCOPD and stable period of COPD in order to evaluate usage of PCT in the prediction of the severity of AeCOPD, and its value on the planing of noninvasive positive pressure ventilation (NPPV. Materials and Methods: In this cross sectional study (2009-2010 118 COPD patients were enrolled, 68 of them (58% were in acute exacerbations (case group. The others had stabile COPD and they were defined as control group. Results: In case group the mean levels of PCT (0.19 ± 0.02 C-Reactive Protein (44.7 ± 5.92, erythrocyte sedimentation rate (28.4 ± 2.65, white blood cell (9.4 ± 0.43 and %neutrophils (69.9 ± 1.22 were significantly higher than controls (P = 0.0001. There was no difference between PCT levels based on stages of COPD. There were significiant differences in mean PCT levels according to type and severity of AeCOPD. Mean PCT level in hospitalized patients receiving NPPV was 0.36 ng/ml, while it was 0.15 ng/ml for those treated without NPPV (P = 0.0001. PCT cut-off value for NPPV indication was determined to be 0.10 ng/ml. Conclusions: PCT levels were found to be higher in AeCOPD patients than in stable COPD patients, as expected. Also mean PCT levels increased especially in cases with severe AeCOPD and those receiving NPPV among them. In the present study, we determined a cut off value of PCT as 0.10 ng/ml as a predictor of necessity of NPPV in AeCOPD.

  18. T1-mapping for assessment of ischemia-induced acute kidney injury and prediction of chronic kidney disease in mice

    To investigate whether T1-mapping allows assessment of acute kidney injury (AKI) and prediction of chronic kidney disease (CKD) in mice. AKI was induced in C57Bl/6N mice by clamping of the right renal pedicle for 35 min (moderate AKI, n = 26) or 45 min (severe AKI, n = 23). Sham animals served as controls (n = 9). Renal histology was assessed in the acute (day 1 + day 7; d1 + d7) and chronic phase (d28) after AKI. Furthermore, longitudinal MRI-examinations (prior to until d28 after surgery) were performed using a 7-Tesla magnet. T1-maps were calculated from a fat-saturated echoplanar inversion recovery sequence, and mean and relative T1-relaxation times were determined. Renal histology showed severe tubular injury at d1 + d7 in both AKI groups, whereas, at d28, only animals with prolonged 45-min ischemia showed persistent signs of AKI. Following both AKI severities T1-values significantly increased and peaked at d7. T1-times in the contralateral kidney without AKI remained stable. At d7 relative T1-values in the outer stripe of the outer medulla were significantly higher after severe than after moderate AKI (138 ± 2 % vs. 121 ± 3 %, p = 0.001). T1-elevation persisted until d28 only after severe AKI. Already at d7 T1 in the outer stripe of the outer medulla correlated with kidney volume loss indicating CKD (r = 0.83). T1-mapping non-invasively detects AKI severity in mice and predicts further outcome. (orig.)

    Conditioning-related gut toxicity can result in a protein-losing enteropathy manifesting as a decline in serum albumin in the peritransplant period. Inspired by the pathogenesis of acute graft-versus-host disease (aGVHD), we hypothesized that the magnitude of decline in serum albumin from the day of conditioning initiation until its nadir in the first 2 weeks after hematopoietic cell transplantation HCT (DeltaAlb) predicts the risk for subsequent severe aGVHD. We reviewed the medical records of all 88 patients with acute myeloid leukemia or myelodysplastic syndrome who underwent highly mucotoxic myeloablative (busulfan/cyclophosphamide or cyclophosphamide/total body irradiation) allogeneic HCT from a matched related donor (MRD) or matched unrelated donor (MUD) at our institution between January 1, 2012 and January 1, 2015. Severe aGVHD was associated with MUD (47% versus 14% with MRD; P = .001) and DeltaAlb, which was significantly greater among patients who developed versus did not develop severe aGVHD (1.2 ± .5 versus .8 ± .4 g/dL, respectively; P HCT, each .1-g/dL increase in DeltaAlb was associated with an approximately 23% increase in the odds of developing severe aGVHD. As an early biomarker of gut damage, DeltaAlb can be incorporated in composite risk models for aGVHD prediction, with hopes for ultimately allowing for individualized GVHD prophylaxis and potential intervention according to the predicted risk.

    2012-12-01

    Full Text Available CONTEXT: Acute diarrhea is a common cause of hospitalization among children under 5 years of age. Knowing the prevalence and risk factors associated with the severity of acute diarrhea is essential to control morbidity and mortality. OBJECTIVE: Describe the prevalence of demographic, epidemiologic and clinical features of children under 6 years of age hospitalized for acute diarrhea, and investigate the association between these determinants and the severity of the diarrheic episode. METHOD: Retrospective, cross-sectional study, during the period from January, 2005 through December, 2008, in the municipality of Juiz de Fora, MG, Brazil. Files from 6,201 children from 0 to 6 years of age, hospitalized in two public teaching institutions (which account for 84% of all the hospitalizations in the municipality, were assessed. Acute diarrhea was defined as the presence of at least three evacuations of liquid or loose stools, within 24 hours, for a maximum period of 14 days. The patients with acute diarrhea were divided in two groups, according to disease severity, severe diarrhea being considered whenever hospitalization lasted for at least 4 days. Epidemiologic and clinical data were assessed and compared through the application of the chi-squared test and the binomial logistic regression model. RESULTS: The prevalence rate for admission due to acute diarrhea was 8.4%. The factors significantly associated with the severity of the diarrheic episode were: age under 6 months (P = 0.01, OR = 2.762; disease onset during fall (P = 0.033, OR = 1.742, presence of fever (P = 0.017, OR = 1.715 and antibiotic use during hospitalization (P = 0.000, OR = 3.872. CONCLUSIONS: Diarrhea is the third most common cause of hospitalization among children under 6 years of age in Juiz de Fora. Young age (under or equal to 6 months, fever, antibiotic use during hospitalization and disease onset during fall are risk factors associated with longer hospital stay.

On the other hand, lipid profile modification after a cardiovascular event related to acute coronary syndrome (ACS has been recognized. The prevalence of conventional risk factors and the lipid profile at the time of admission in patients with ACS and significant CAD (stenosis ≥50% determined through coronary angiography is not well described. Methods: We studied 3,447 patients with a diagnosis of ACS and significant CAD with stenosis ≥50%, as shown on angiography. We recorded the presence of conventional risk factors, including smoking, hypertension, dyslipidemia, and diabetes. In addition, we analyzed the lipid profiles within the first 24 hours of admission. We analyzed the studied population and compared findings according to sex.Results: Most patients (81.7% were male. ST-elevation myocardial infarction was present in 51.3% of patients, and non-ST-elevation acute coronary syndrome was present in 48.7%. The most frequent risk factor was smoking, which was present in 68% of patients, followed by hypertension (57.8%, dyslipidemia (47.5%, and diabetes (37.7%. In women, the most frequent risk factors were hypertension, diabetes, and dyslipidemia, whereas in men, smoking was the most frequent. We identified at least one risk factor in 95.7% of all patients, two or three risk factors in 62%, and four risk factors in 8.6% of patients. The lipid profile analysis revealed that

    In patients hospitalised with acute coronary syndromes (ACS) and congestive heart failure (CHF), evidence suggests opportunities for improving in-hospital and after-hospital care, patient self-care, and hospital-community integration. A multidisciplinary quality improvement program was designed and instigated in Brisbane in October 2000 involving 250 clinicians at three teaching hospitals, 1080 general practitioners (GPs) from five Divisions of General Practice, 1594 patients with ACS and 904 patients with CHF. Quality improvement interventions were implemented over 17 months after a 6-month baseline period and included: clinical decision support (clinical practice guidelines, reminders, checklists, clinical pathways); educational interventions (seminars, academic detailing); regular performance feedback; patient self-management strategies; and hospital-community integration (discharge referral summaries; community pharmacist liaison; patient prompts to attend GPs). Using a before-after study design to assess program impact, significantly more program patients compared with historical controls received: ACS: Angiotensin-converting enzyme (ACE) inhibitors and lipid-lowering agents at discharge, aspirin and beta-blockers at 3 months after discharge, inpatient cardiac counselling, and referral to outpatient cardiac rehabilitation. CHF: Assessment for reversible precipitants, use of prophylaxis for deep-venous thrombosis, beta-blockers at discharge, ACE inhibitors at 6 months after discharge, imaging of left ventricular function, and optimal management of blood pressure levels. Risk-adjusted mortality rates at 6 and 12 months decreased, respectively, from 9.8% to 7.4% (P = 0.06) and from 13.4% to 10.1% (P = 0.06) for patients with ACS and from 22.8% to 15.2% (P improvement programs that feature multifaceted interventions across the continuum of care can change clinical culture, optimise care and improve clinical outcomes.

    Repeat hospitalization due to acute heart failure (HF) is a global public health problem that markedly impacts on health resource use. Identifying novel predictors of rehospitalization would help physicians to determine the optimal postdischarge plan for preventing HF rehospitalization. Nonalcoholic fatty liver disease (NAFLD) is an emerging risk factor for many heart diseases, including HF. We assessed whether NAFLD at hospital admission predicts 1-year all-cause rehospitalization in patients with acute HF. We enrolled all patients consecutively admitted for acute HF to our General Medicine Division, from January 2013 to April 2014, after excluding patients with acute myocardial infarction, severe heart valve diseases, malignancy, known liver diseases, and those with volume overload related to extracardiac causes. NAFLD was diagnosed by ultrasonography and exclusion of competing etiologies. The primary outcome of the study was the 1-year all-cause rehospitalization rate. Among the 107 patients enrolled in the study, the cumulative rehospitalization rate was 12.1% at 1 month, 25.2% at 3 months, 29.9% at 6 months, and 38.3% at 1 year. Patients with NAFLD had markedly higher 1-year rehospitalization rates than those without NAFLD (58% vs 21% at 1 y; P < 0.001 by the log-rank test). Cox regression analysis revealed that NAFLD was associated with a 5.5-fold increased risk of rehospitalization (adjusted hazard ratio 5.56, 95% confidence interval 2.46-12.1, P < 0.001) after adjustment for multiple HF risk factors and potential confounders. In conclusion, NAFLD was independently associated with higher 1-year rehospitalization in patients hospitalized for acute HF. PMID:26886619

    Diseases of the liver and biliary system are common causes of acute abdominal pain and gallstone disease predisposes to cholecystitis and cholangiolithiasis. Sonography is the method of choice for the assessment of cholecystitis, whereas magnetic resonance cholangiopancreaticography (MRCP) is the standard technique to detect stones in the common bile duct. Multi-detector computed tomography (MDCT) is ideal for detection of associated complications, including abscess formation and gall stone ileus. Pyogenic, amebic and fungal liver abscesses are reliably diagnosed with MDCT which can also be used for interventional radiologic therapy of liver abscesses by percutaneous aspiration or drainage procedures. The second most common cause of liver rupture after blunt trauma is spontaneous rupture of hypervascular liver tumors (i.e., HCC, adenoma, angiosarcoma) and due to medical procedures. Multi-phase contrast-enhanced MDCT can reliably detect active bleeding to guide further therapy in these cases. (orig.)

  8. Retrocrural space involvement on computed tomography as a predictor of mortality and disease severity in acute pancreatitis.

    Haotong Xu

    Full Text Available Because computed tomography (CT has advantages for visualizing the manifestation of necrosis and local complications, a series of scoring systems based on CT manifestations have been developed for assessing the clinical outcomes of acute pancreatitis (AP, including the CT severity index (CTSI, modified CTSI, etc. Despite the internationally accepted CTSI having been successfully used to predict the overall mortality and disease severity of AP, recent literature has revealed the limitations of the CTSI. Using the Delphi method, we establish a new scoring system based on retrocrural space involvement (RCSI, and compared its effectiveness at evaluating the mortality and severity of AP with that of the CTSI.We reviewed CT images of 257 patients with AP taken within 3-5 days of admission in 2012. The RCSI scoring system, which includes assessment of infectious conditions involving the retrocrural space and the adjacent pleural cavity, was established using the Delphi method. Two radiologists independently assessed the RCSI and CTSI scores. The predictive points of the RCSI and CTSI scoring systems in evaluating the mortality and severity of AP were estimated using receiver operating characteristic (ROC curves.The RCSI score can accurately predict the mortality and disease severity. The area under the ROC curve for the RCSI versus CTSI score was 0.962±0.011 versus 0.900±0.021 for predicting the mortality, and 0.888±0.025 versus 0.904±0.020 for predicting the severity of AP. Applying ROC analysis to our data showed that a RCSI score of 4 was the best cutoff value, above which mortality could be identified.The Delphi method was innovatively adopted to establish a scoring system to predict the clinical outcome of AP. The RCSI scoring system can predict the mortality of AP better than the CTSI system, and the severity of AP equally as well.

  9. Emerging nalidixic acid and ciprofloxacin resistance in non-typhoidal Salmonella isolated from patients having acute diarrhoeal disease

    Non-typhoidal Salmonella are one of the key etiological agents of diarrhoeal disease. The appearence of multiple drung resistance along with resistance to quinolones in this bacterium poses a serious therapeutic problem. We determined the prevalence of nalidixic acid and ciprofloxacin resistance in non-typhodial Salmonella isolated from faecal samples of patients with acute diarroheal disease attending the outpatient and inpatient department of a hospital in Saudi Arabia during the years 1999 to 2002. Non-typhodial Salmonella were isolated from faecal samples. Antimicrobial susceptibility was tested by the disc diffusion test. MICs to nalidixic acid and ciprofloxacinwere determined by the agar dilution method. During the study period , 524 strains of non-typhoidal Salmonella were isolated. Strains belonging to serogroup C1were the commonest (41.4%) followed by serogroups B and D (15.6% and 14.5%, respectively). Resistance to ampicillin was observed in 22.9% and to trimethoprim/sulphamethoxazole in 18.5%of the strains. Nalidixic acid resistance was encounterd in 9.9% and ciprofloxacin esistance in 2.3% of the strains. Resistance to nalidixic acid significantly increased from 0.1% in 1999 to 5.51% in 2002 ( p=0.0007)and ciprofloxacin resistance increased significantly from 0.1% in 1999 to 0.9% in 2002( p=0.0001). MICs to nalidixic acid and ciprofloxacin were determined among 29 nalidixic acid-resistant strains of non-typhoidal salmonella isolated during 2002. The MIC was >256 ug /ml to nalidixic acid and 8 to 16 ug/ml to ciprofloxacin. The increasing rate of antimicrobial resistance encountered among non-tyophoidal Salmonella necessiate the judicious use of these drugs in humans. Moreover, these findings support the concern that the use of quinolones in animal feed may lead to an increasein resistance and should should be restricted. (author)

We hypothesized that poor sleep quality in otherwise stable patients predicted exacerbations in these patients. Methods: This is a secondary analysis of the results of a previously published randomized trial of azithromycin in 1,117 patients with moderate to severe COPD who were clinically stable on enrollment. Sleep quality was measured using the Pittsburgh Sleep Quality Index. Other quality of life indices included the Medical Outcome Study 36-item Short Form Health Survey and the St Georges Respiratory Questionnaire. Outcomes included time to first exacerbation and exacerbation rate. Results: Sleep quality was “poor” (Pittsburgh Sleep Quality Index >5 in 53% of participants but was not related to age or severity of airflow obstruction. Quality of life scores were worse in “poor” sleepers than in “good” sleepers. Major classes of comorbid conditions, including psychiatric, neurologic, and musculoskeletal disease, were more prevalent in the “poor” sleepers. Unadjusted time to first exacerbation was shorter (190 versus 239 days and exacerbation rate (1

    Ronald W Irwin

    Full Text Available To develop allopregnanolone as a therapeutic for Alzheimer's disease, we investigated multiple formulations and routes of administration in translationally relevant animal models of both sexes. Subcutaneous, topical (transdermal and intranasal, intramuscular, and intravenous allopregnanolone were bolus-administered. Pharmacokinetic analyses of intravenous allopregnanolone in rabbit and mouse indicated that peak plasma and brain levels (3-fold brain/plasma ratios at 5min were sufficient to activate neuroregenerative responses at sub-sedative doses. Slow-release subcutaneous suspension of allopregnanolone displayed 5-fold brain/plasma ratio at Cmax at 30min. At therapeutic doses by either subcutaneous or intravenous routes, allopregnanolone mouse plasma levels ranged between 34-51ng/ml by 30min, comparable to published endogenous human level in the third trimester of pregnancy. Exposure to subcutaneous, topical, intramuscular, and intravenous allopregnanolone, at safe and tolerable doses, increased hippocampal markers of neurogenesis including BrdU and PCNA in young 3xTgAD and aged wildtype mice. Intravenous allopregnanolone transiently and robustly phosphorylated CREB within 5min and increased levels of neuronal differentiation transcription factor NeuroD within 4h. Neurogenic efficacy was achieved with allopregnanolone brain exposure of 300-500hr*ng/g. Formulations were tested to determine the no observable adverse effect level (NOAEL and maximally tolerated doses (MTD in male and female rats by sedation behavior time course. Sex differences were apparent, males exhibited ≥40% more sedation time compared to females. Allopregnanolone formulated in sulfobutyl-ether-beta-cyclodextrin at optimized complexation ratio maximized allopregnanolone delivery and neurogenic efficacy. To establish the NOAEL and MTD for Allo-induced sedation using a once-per-week intravenous regenerative treatment regimen: In female rats the NOAEL was 0.5mg/kg and MTD 2mg

  12. Acute Kidney Injury in Elderly Patients With Chronic Kidney Disease: Do Angiotensin-Converting Enzyme Inhibitors Carry a Risk?

    Chaumont, Martin; Pourcelet, Aline; van Nuffelen, Marc; Racapé, Judith; Leeman, Marc; Hougardy, Jean-Michel

    2016-06-01

    In contrast to angiotensin receptor blockers (ARBs), mainly excreted by the liver, the dosage of angiotensin-converting enzyme (ACE) inhibitors, cleared by the kidney, must be adapted to account for renal clearance in patients with chronic kidney disease (CKD) to avoid acute kidney injury (AKI). Community-acquired AKI and the use of ACE inhibitors or ARBs in the emergency department were retrospectively assessed in 324 patients with baseline stage 3 or higher CKD. After stepwise regression analysis, the use of ACE inhibitors (odds ratio [OR], 1.9; 95% confidence interval [CI], 1.1-3.1; P=.02) and the presence of dehydration (OR, 30.8; 95% CI, 3.9-239.1) were associated with AKI. A total of 45% of patients using ACE inhibitors experienced overdosing, which causes most of the excess risk of AKI. These results suggest that dosage adjustment of ACE inhibitors to renal function or substitution of ACE inhibitors with ARBs could reduce the incidence of AKI. Moreover, ACE inhibitors and ARBs should be stopped in cases of dehydration. PMID:27080620

  13. Focal bowel wall changes detected with colour Doppler ultrasound: diagnostic value in acute non-diverticular diseases of the colon.

    Danse, E M; Jamart, J; Hoang, P; Laterre, P F; Kartheuser, A; Van Beers, B E

    2004-11-01

    We performed a study to determine if colour Doppler findings may help to identify the cause of wall thickening in acute non-diverticular diseases of the colon. The study group included 66 patients admitted to the emergency department with a final diagnosis of infectious colitis (n=23), inflammatory colitis (n=10), ischaemic colitis (n=23) and malignant tumours (n=10). The following ultrasound features were assessed: maximal wall thickness, wall stratification, arterial flow in the colonic wall and arteriolar resistive index. Higher values of wall thickness were observed in malignant tumour (18.2+/-6.2 mm, p<0.001). Moderately thickened wall (6.6+/-1.3 mm, p< or =0.06), preserved stratification (90% versus 46% in the remainder of the study population) and lower resistive index (0.51+/-0.10, p< or =0.05) were significantly related to inflammatory colitis. Absence of arterial flow was more frequently observed in ischaemia (43% versus 12% in the remainder of the study population). In conclusion, despite some overlap, both ultrasound and colour Doppler features are helpful in the differential diagnosis of colonic thickening related to non-diverticular colonic lesions.

    2015-10-01

    Full Text Available Immune cells (IC play a crucial role in murine stroke pathophysiology. However, data are limited on the role of these cells in ischemic stroke in humans. We therefore aimed to characterize and compare peripheral IC subsets in patients with acute ischemic stroke/transient ischemic attack (AIS/TIA, chronic cerebrovascular disease (CCD and healthy volunteers (HV. We conducted a case-control study of patients with AIS/TIA (n = 116 or CCD (n = 117, and HV (n = 104 who were enrolled at the University Hospital Würzburg from 2010 to 2013. We determined the expression and quantity of IC subsets in the three study groups and performed correlation analyses with demographic and clinical parameters. The quantity of several IC subsets differed between the AIS/TIA, CCD, and HV groups. Several clinical and demographic variables independently predicted the quantity of IC subsets in patients with AIS/TIA. No significant changes in the quantity of IC subsets occurred within the first three days after AIS/TIA. Overall, these findings strengthen the evidence for a pathophysiologic role of IC in human ischemic stroke and the potential use of IC-based biomarkers for the prediction of stroke risk. A comprehensive description of IC kinetics is crucial to enable the design of targeted treatment strategies.

    Full Text Available 191 consecutive unselected children with acute lymphoblastic leukemia aged from 1 to 16 years were enrolled in the study. Bone marrow samples were obtained at the time of initial diagnostics as well as at days 15 (n = 188, 36 (n = 191, and 85 (n = 187 of remission induction. Minimal residual disease (MRD was assessed by 6–10-color flow cytometry. Flow cytometry data at day 15 allowed distinguishing three patients groups with significantly different outcome (p ˂ 0.0001: 35.64 % patients with MRD < 0.1 % represented 5-year event-free survival (EFS of 100 %; 48.40 % cases with 0.1 % ≤ MRD< 10 % had EFS 84.6 ± 4.2 %; 15.96 % patients with very high MRD (≥ 10 % belonged to group with poor outcome (EFS 56.7 ± 9.0 %. At the end of remission induction (day 36 36 children (18.85 % with MRD higher than 0.1 % had significantly worse outcome compared to remaining ones (EFS 49.4 ± 9.0 and 93.5 ± 2.1 % respectively; p ˂ 0.0001. From a clinical standpoint it is relevant to evaluate both low-risk and high-risk criteria. Multivariate analysis showed that day 15 MRD data is better for low-risk patients definition while end-induction MRD is the strongest unfavorable prognostic factor.

  16. Extraction of Trypanosoma cruzi DNA from food: a contribution to the elucidation of acute Chagas disease outbreaks

    Renata Trotta Barroso Ferreira

    2016-04-01

    Full Text Available Abstract: INTRODUCTION: Before 2004, the occurrence of acute Chagas disease (ACD by oral transmission associated with food was scarcely known or investigated. Originally sporadic and circumstantial, ACD occurrences have now become frequent in the Amazon region, with recently related outbreaks spreading to several Brazilian states. These cases are associated with the consumption of açai juice by waste reservoir animals or insect vectors infected with Trypanosoma cruzi in endemic areas. Although guidelines for processing the fruit to minimize contamination through microorganisms and parasites exist, açai-based products must be assessed for quality, for which the demand for appropriate methodologies must be met. METHODS: Dilutions ranging from 5 to 1,000 T. cruzi CL Brener cells were mixed with 2mL of acai juice. Four Extraction of T. cruzi DNA methods were used on the fruit, and the cetyltrimethyl ammonium bromide (CTAB method was selected according to JRC, 2005. RESULTS: DNA extraction by the CTAB method yielded satisfactory results with regard to purity and concentration for use in PCR. Overall, the methods employed proved that not only extraction efficiency but also high sensitivity in amplification was important. CONCLUSIONS: The method for T. cruzi detection in food is a powerful tool in the epidemiological investigation of outbreaks as it turns epidemiological evidence into supporting data that serve to confirm T. cruzi infection in the foods. It also facilitates food quality control and assessment of good manufacturing practices involving acai-based products.

    2013-12-01

    Full Text Available Background: This study reported the incidence and prognostic outcome of chronic obstructive lung disease (COPD patients with acute ST-segment elevation myocardial infarction (STEMI undergoing primary percutaneous coronary intervention (PCI. Methods: Between January 2002 and May 2011, totally 1554 consecutive patients who experienced STEMI undergoing primary PCI were enrolled into the study. Results: Of the 1554 patients, 124 (9.7% with diagnosis of COPD and 1430 (90.3% without COPD were categorized into group 1 and group 2. Although no difference in in-hospital mortality was noted between the two groups (p = 0.726. However, the hospitalization duration was notably longer (p = 0.003, the incidences of recurrent MI and re-hospitalization for congestive heart failure were significantly higher in group 1 than in group 2 (all p < 0.02. Although Kaplan-Meier analysis demonstrated that the incidence of freedom from one-year major adverse clinical outcome (MACO (defined as recurrent MI, re-admission for congestive heart failure was significantly lower in group 1 than group 2 (p = 0.012, multivariate Cox regression analysis showed COPD was not an independent predictor of MACO-free time after adjusting traditional risk factors. Conclusion: COPD was not an independent predictor of short-term and medium-term MACO in patients with STEMI undergoing primary PCI.

  18. Defecation of a colon cast as a rare presentation of acute graft-versus-host disease

    Diffuse involvement of the gastrointestinal tract by graft versus host disease (GVHD) is a common complication of allogeneic hematopoietic stem cell transplant (HSCT). Gastrointestinal GVHD usually presents 3 or more weeks after HSCT and is characterized by profuse diarrhea, anorexia, nausea, vomiting, abdominal pain and gastrointestinal bleeding. We report a case of a 23 year old male who had undergone allogeneic HSCT and presented with bloody diarrhea on the 90th day post-HSCT. On the fourth day of admission, the patient passed per rectum a 27-cm long pinkish colored fleshy material recognized as a colon cast. Sigmoidoscopy showed a congested and erythematous rectum with the remaining portion of the colon cast attached to the proximal part of the sigmoid colon. A biopsy from the rectal wall was suggestive of grade 4 GVHD. The patient was treated with methylprednisolone, cyclosporine and mycophenolate mofetil, with a partial response (diarrhea and abdominal pain improved), but then he developed multiple other medical complications and died after 3 months.

  19. Mesenchymal Stem Cell Therapy in the Treatment of Acute and Chronic Graft versus Host Disease

    SimonRobinson

    2011-07-01

    Full Text Available Mesenchymal stem cells (MSC are a cellular component of the supportive microenvironment (stroma found in the bone marrow, umbilical cord, placenta and adipose tissues. In addition to providing cellular and extracellular cues to support the proliferation and differentiation of cells that comprise functional tissues, MSC also contribute to tissue repair and have immunomodulatory properties. Their ability to modulate immunologic reactions while themselves not provoking immunologic responses from alloreactive T-lymphocytes and/or other effector cells, make MSC a potentially ideal therapeutic agent with which to treat graft versus host disease (GvHD following hematopoietic transplantation. Despite in vitro experiments confirming that MSC suppress mixed lymphocyte reactions (MLR and in vivo evidence from mouse models that show evidence that MSC can ameliorate GvHD, clinical trials to date using MSC to treat GvHD have shown mixed results. Whether this is a consequence of suboptimal timing and dose of administered MSC remains to be clarified. It is clear that immunomodulatory potential of MSC as a cellular therapy for GvHD remains to be realized in the clinic.

    2006-05-01

    Maple syrup urine disease (MSUD, MIM 248600) can be complicated by metabolic crises necessitating extracorporeal removal therapy (ECRT). Since leucine levels are usually not immediately available during therapy, an accurate kinetic model of leucine plasma levels during removal would be useful to establish the duration of ECRT. Such a kinetic model is available for neonates undergoing continuous ECRT (CECRT) with a leucine clearance>or=35 ml min-1 1.73 m-2. The current study tests the validity of this model in older children. Plasma leucine levels were obtained from eleven ECRT sessions [seven CECRT and four intermittent hemodialysis (HDi) sessions] in seven children aged 1-14 years. No hemodynamic instability or neurological complications were observed during treatment. HDi provided a higher leucine clearance and required shorter sessions than CECRT (5.4+/-0.6 vs. 17.1+/-6.0 h). All patients regained precrisis neurological status except for one patient who had severe neurological damage (severe cerebral edema) at the time of dialysis and subsequently died despite efficient leucine removal. A leucine clearance>or=50 ml min-1 1.73 m-2 is required to obtain a kinetic model similar to that reported in neonates, both with CECRT and HDi. This model should be helpful in predicting the duration of therapy needed to attain desired leucine levels. PMID:16518628

  1. Chest X-ray findings in the acute phase of Kawasaki disease

    We reviewed the chest X-ray (CXR) findings and clinical courses of 129 patients with Kawasaki disease and found abnormal CXR findings in 14.7% of the patients. Reticulogranular pattern was the most frequent abnormality (89.5%), while peribronchial cuffing (21.1%), pleural effusion (15.8%), atelectasis (10.5%) and air trapping (5.3%) were also seen. In each of these patients, CXR abnormalities appeared within 10 days after the onset of illness. In the group with abnormal CXR findings, a statistically significant increase was noted in duration of fever, incidence of adventitious sounds, serum CPR levels and incidence of coronary arterial lesions and pericardial effusion, as compared with the group having normal CXR findings. The pathological basis of these CXR changes is not clear, since no biopsy or autopsy specimen was obtained from these patients. Since none of these patients showed definite heart failure, it is difficult to consider that abnormal CXR findings were due to heart failure. On the other hand, physical signs and previous pathological reports suggested that the causes of abnormal CXR findings were lower respiratory tract inflammation and/or pulmonary arteritis. (orig.)

  4. Paracoccidioides brasilienses isolates obtained from patients with acute and chronic disease exhibit morphological differences after animal passage

    SVIDZINSKI Terezinha Inez Estivalet

    1999-01-01

    Full Text Available The basis for virulence in Paracoccidioides brasiliensis is not completely understood. There is a consensus that the sequencial in vitro subcultivation of P. brasiliensis leads to loss of its pathogenicity, which can be reverted by reisolation from animal passage. Attention to morphological and biochemical properties that are regained or demonstrated after animal passage may provide new insights into factors related to the pathogenicity and virulence of P. brasiliensis. We evaluated morphological characters: the percentage of budding cells, number of buds by cell and the diameter of 100 mother cells of yeast-like cells of 30 P. brasiliensis isolates, before and after animal passage. The isolates were obtained from patients with different clinical forms of paracoccidioidomycosis (PCM: acute form (group A, n=15 and chronic form (group C, n=15. The measurement of the yeast cell sizes was carried out with the aid of an Olympus CBB microscope coupled with a micrometer disc. We measured the major transverse and longitudinal axes of 100 viable cells of each preparation. The percentage of budding cells as also the number of buds by cell was not influenced by animal passage, regardless of the source of the strain (acute or chronic groups. The size values of P. brasiliensis isolates from groups A and C, measured before the animal passage exhibited the same behavior. After animal passage, there was a statistically significant difference between the cell sizes of P. brasiliensis isolates recovered from testicles inoculated with strains from groups A and C. The maximum diameter of mother cells from group A isolates exhibited a size of 42.1mm in contrast with 32.9mm exhibited by mother cells from group C (p<0.05. The diameter of 1500 mother cells from group A isolates exhibited a medium size of 16.0mm (SD ± 4.0, a value significantly higher than the 14.1mm (SD = ± 3.3 exhibited by 1500 mother cells from group C isolates (p<0.05.

  5. Diagnostic Algorithm in the Management of Acute Febrile Abdomen in Patients with Autosomal Dominant Polycystic Kidney Disease

    Neuville, Marie; Hustinx, Roland; Jacques, Jessica; Krzesinski, Jean-Marie

    2016-01-01

    Background Acute febrile abdomen represents a diagnostic challenge in patients with autosomal dominant polycystic kidney disease (ADPKD). Although criteria have been proposed for cyst infection (CyI) and hemorrhage (CyH), there is a lack of comparative assessments. Furthermore, distinguishing cystic from non-cystic complications remains problematic. Design ADPKD patients presenting with abdominal pain and/or fever between 01/2005 and 06/2015 were retrospectively identified in a systematic computerized billing database. CyH was defined as spontaneous intracystic density above 50 Hounsfield units on computed tomography (CT). CyI was definite if confirmed by cyst puncture, and probable if 4 criteria were met: 3-day fever, loin/liver tenderness, C-reactive protein (CRP) plasma levels >50mg/L and no CT evidence for CyH. Other episodes were grouped as inflammation of unknown origin (IUO). Results Among a cohort of 173 ADPKD patients, 101 presented with 205 episodes of abdominal pain (n = 172) and/or fever (n = 33). 20 patients experienced 30 CyH, whereas 16 presented 23 episodes of definite (n = 11) or probable (n = 12) CyI. 35 IUO were observed in 31 patients. Clinically, fever was observed in 7% vs. 100% vs. 66% of CyH, CyI and IUO, respectively. Biologically, CRP cut-off at 70 mg/dl showed 92% sensitivity and 81% specificity in CyI diagnosis. Urine or blood cultures remained sterile in >90% of CyH, but were contributive in 53.4% of CyI and IUO, with a 74.2% prevalence for E. coli. Radiologically, ultrasounds, CT and magnetic resonance diagnosed CyI in 2.6%, 20% and 16.7% of cases, respectively. 18F-FDG positron-emission tomography (PET)/CT was done within a median period of 7 days post antibiotics, and significantly changed patient management in 71.4%. Conclusions This retrospective single-center series underscores the usefulness of clinical–fever–and biological–CRP–parameters, but emphasizes the limitations of bacteriological and radiological investigations

    Soto-Rodriguez, Sonia A.; Gomez-Gil, Bruno; Lozano-Olvera, Rodolfo; Betancourt-Lozano, Miguel; Morales-Covarrubias, Maria Soledad

    2014-01-01

    Moribund shrimp affected by acute hepatopancreatic necrosis disease (AHPND) from farms in northwestern Mexico were sampled for bacteriological and histological analysis. Bacterial isolates were molecularly identified as Vibrio parahaemolyticus by the presence of the tlh gene. The tdh-negative, trh-negative, and tlh-positive V. parahaemolyticus strains were further characterized by repetitive extragenic palindromic element-PCR (rep-PCR), and primers AP1, AP2, AP3, and AP and an ems2 IQ2000 det...

  12. Pretransplant helper T-lymphocyte determination in bone marrow donors: acute graft-versus-host disease prediction and relation with long-term survival

    Winandy, Marie; Lewalle, Philippe; Deneys, Véronique; Ferrant, Augustin; Bruyère, Marc

    1999-01-01

    Helper T-lymphocyte precursor (HTLp) frequency from 19 allogeneic bone marrow donors was tested to detect weak antigenic differences with the recipient, and then compared to the outcome. HTLp frequency was estimated in limiting dilution cultures, and HLA-DR and CD 80 expression by stimulating cells was measured by flow cytometry. 12/19 patients experienced acute graft-versus-host disease (aGVHD) grade II–IV. A good correlation was found between high pretransplant HTLp ...

    Patients with metabolic syndrome are at high-risk for development of atherosclerosis and cardiovascular events. The objective of this study was to examine the major determinants of coronary disease severity, including those coronary risk factors associated with metabolic syndrome, during the early period after an acute coronary episode. We tested the hypothesis that inflammatory markers, especially highly sensitive C-reactive protein (hsCRP), are related to coronary atherosclerosis, in additi...

    2013-01-01

    Introduction Plasma neutrophil gelatinase-associated lipocalin (NGAL) is reportedly useful for post-cardiac surgery acute kidney injury (AKI). Although chronic kidney disease (CKD) is a strong risk factor for AKI development, no clinical evaluation of plasma NGAL has specifically examined AKI occurring in patients with CKD. This study evaluated plasma NGAL in AKI superimposed on CKD after cardiac surgery. Methods This study prospectively evaluated 146 adult patients with scheduled cardiac sur...

    Gammelager, Henrik; Christiansen, Christian Fynbo; Johansen, Martin Berg; Tønnesen, Else; Jespersen, Bente; Sørensen, Henrik Toft

    2014-01-01

    Introduction Acute kidney injury (AKI) is common among intensive care unit (ICU) patients, but follow-up data on subsequent risk of cardiovascular disease remain sparse. We examined the impact of AKI on three-year risk of first-time heart failure, myocardial infarction (MI), and stroke among ICU patients surviving to hospital discharge, and whether this risk is modified by renal recovery before hospital discharge. Methods We used population-based medical registries to identify all adult patie...

  18. β-Blockers for the prevention of acute exacerbations of chronic obstructive pulmonary disease (βLOCK COPD): a randomised controlled study protocol

    Bhatt, Surya P.; Connett, John E.; Voelker, Helen; Lindberg, Sarah M; Westfall, Elizabeth; Wells, J. Michael; Lazarus, Stephen C.; Criner, Gerard J.; Dransfield, Mark T

    2016-01-01

    Introduction A substantial majority of chronic obstructive pulmonary disease (COPD)-related morbidity, mortality and healthcare costs are due to acute exacerbations, but existing medications have only a modest effect on reducing their frequency, even when used in combination. Observational studies suggest β-blockers may reduce the risk of COPD exacerbations; thus, we will conduct a randomised, placebo-controlled trial to definitively assess the impact of metoprolol succinate on the rate of CO...

    Background: Antibiotic and oral corticosteroid prescribing rate in patients suffering from acute exacerbations of chronic obstructive pulmonary disease (COPD) or asthma in general practice are only sparsely described. Our aim was to identify predictors for such prescribing when results from CRP testing, spirometry, and pulse oximetry are available. Methods: Patients aged 40 years or more diagnosed with asthma, COPD or both, the previous five years from seven general practice offices in Norway...

  20. Genomic and Bioinformatics Analysis of HAdV-4, a Human Adenovirus Causing Acute Respiratory Disease: Implications for Gene Therapy and Vaccine Vector Development

    Purkayastha, Anjan; Ditty, Susan E.; Su, Jing; McGraw, John; Hadfield, Ted L.; Tibbetts, Clark; Seto, Donald

    2005-01-01

    Human adenovirus serotype 4 (HAdV-4) is a reemerging viral pathogenic agent implicated in epidemic outbreaks of acute respiratory disease (ARD). This report presents a genomic and bioinformatics analysis of the prototype 35,990-nucleotide genome (GenBank accession no. AY594253). Intriguingly, the genome analysis suggests a closer phylogenetic relationship with the chimpanzee adenoviruses (simian adenoviruses) rather than with other human adenoviruses, suggesting a recent origin of HAdV-4, and...

  1. Photorhabdus insect-related (Pir) toxin-like genes in a plasmid of Vibrio parahaemolyticus, the causative agent of acute hepatopancreatic necrosis disease (AHPND) of shrimp

    Han, Jee Eun; Kathy F.J. Tang; Tran, Loc H.; Lightner, Donald V.

    2015-01-01

    The 69 kb plasmid pVPA3-1 was identified in Vibrio parahaemolyticus strain 13-028/A3 that can cause acute hepatopancreatic necrosis disease (AHPND). This disease is responsible for mass mortalities in farmed penaeid shrimp and is referred to as early mortality syndrome (EMS). The plasmid has a GC content of 45.9% with a copy number of 37 per bacterial cell as determined by comparative quantitative PCR analyses. It consists of 92 open reading frames that encode mobilization proteins, replicati...

  2. Molecular and clinical evaluation of the acute human parvovirus B19 infection: comparison of two cases in children with sickle cell disease and discussion of the literature

    Svetoslav Nanev Slavov

    2013-02-01

    Full Text Available Human parvovirus B19 is a well-known cause of severe conditions in patients with sickle cell disease, but the molecular mechanisms of the infection are insufficiently understood. The different clinical outcome of the acute parvovirus B19 infection in two pediatric patients with sickle cell disease has been examined. One of them developed life-threatening condition requiring emergency transfusions, while the other had asymptomatic infection, diagnosed occasionally. Both cases had high viral load and identical subgenotype, indicating that the viral molecular characteristics play a minimal role in the infection outcome.

  3. Microevolution of the chromosomal region of acute disease antigen A (adaA in the query (Q fever agent Coxiella burnetii.

    Dimitrios Frangoulidis

    Full Text Available The acute disease antigen A (adaA gene is believed to be associated with Coxiella burnetii strains causing acute Q fever. The detailed analysis of the adaA genomic region of 23 human- and 86 animal-derived C. burnetii isolates presented in this study reveals a much more polymorphic appearance and distribution of the adaA gene, resulting in a classification of C. burnetii strains of better differentiation than previously anticipated. Three different genomic variants of the adaA gene were identified which could be detected in isolates from acute and chronic patients, rendering the association of adaA positive strains with acute Q fever disease disputable. In addition, all adaA positive strains in humans and animals showed the occurrence of the QpH1 plasmid. All adaA positive isolates of acute human patients except one showed a distinct SNP variation at position 431, also predominant in sheep strains, which correlates well with the observation that sheep are a major source of human infection. Furthermore, the phylogenetic analysis of the adaA gene revealed three deletion events and supported the hypothesis that strain Dugway 5J108-111 might be the ancestor of all known C. burnetii strains. Based on our findings, we could confirm the QpDV group and we were able to define a new genotypic cluster. The adaA gene polymorphisms shown here improve molecular typing of Q fever, and give new insights into microevolutionary adaption processes in C. burnetii.

  4. Design and baseline characteristics of a coronary heart disease prospective cohort: two-year experience from the strategy of registry of acute coronary syndrome study (ERICO study

    Alessandra C. Goulart

    2013-01-01

    Full Text Available OBJECTIVES: To describe the ERICO study (Strategy of Registry of Acute Coronary Syndrome, a prospective cohort to investigate the epidemiology of acute coronary syndrome. METHODS: The ERICO study, which is being performed at a secondary general hospital in São Paulo, Brazil, is enrolling consecutive acute coronary syndrome patients who are 35 years old or older. The sociodemographic information, medical assessments, treatment data and blood samples are collected at admission. After 30 days, the medical history is updated, and additional blood and urinary samples are collected. In addition, a retinography, carotid intima-media thickness, heart rate variability and pulse-wave velocity are performed. Questionnaires about food frequency, physical activity, sleep apnea and depression are also applied. At six months and annually after an acute event, information is collected by telephone. RESULTS: From February 2009 to September 2011, 738 patients with a diagnosis of an acute coronary syndrome were enrolled. Of these, 208 (28.2% had ST-elevation myocardial infarction (STEMI, 288 (39.0% had non-ST-elevation myocardial infarction (NSTEMI and 242 (32.8% had unstable angina (UA. The mean age was 62.7 years, 58.5% were men and 77.4% had 8 years or less of education. The most common cardiovascular risk factors were hypertension (76% and sedentarism (73.4%. Only 29.2% had a prior history of coronary heart disease. Compared with the ST-elevation myocardial infarction subgroup, the unstable angina and non-ST-elevation myocardial infarction patients had higher frequencies of hypertension, diabetes, prior coronary heart disease (p<0.001 and dyslipidemia (p = 0.03. Smoking was more frequent in the ST-elevation myocardial infarction patients (p = 0.006. CONCLUSIONS: Compared with other hospital registries, our findings revealed a higher burden of CV risk factors and less frequent prior CHD history.

    2002-01-15

    We investigated the association between Helicobacter pylori (H. pylori) infection and coronary artery disease (CAD) in 2 study populations: (1) a cross-sectional study to determine risk of having CAD, and (2) a longitudinal study to determine risk of acute myocardial infarction (AMI) or death over a mean follow-up period of 3 years in patients with angiographically documented CAD. Blood samples were tested for serum immunoglobulin G antibodies to H. pylori and C-reactive protein (CRP) levels. Study 1: Of 391 patients (62% men, mean age 57 years), 41% had antibodies to H. pylori. CAD prevalence was 70% in H. pylori seropositive patients and 59% in seronegative patients (p = 0.03). Elevated CRP levels (>0.5 mg/dl) were significantly higher in patients with than without CAD (p = 0.02). By univariate analysis, CAD prevalence significantly increased stepwise depending on H. pylori seropositivity and elevated CRP levels (p = 0.008). Significance was lost after adjustment for traditional risk factors. Further analyses revealed that age was the critical confounder. Study 2: Of 929 patients (77% men, mean age 65 years), 56% had antibodies to H. pylori. By univariate analysis, the incidence of AMI or death was 22% in H. pylori seropositive patients and 18% in seronegative patients (p = 0.1). The adjusted hazard ratio of AMI or death for H. pylori seropositivity was 1.12 (95% confidence interval 0.81 to 1.54). Our data suggest that prior infection with H. pylori is not a major factor determining either risk of CAD, AMI, or death in patients with CAD. PMID:11792334

  6. CD8+ T-Cells Count in Acute Myocardial Infarction in HIV Disease in a Predominantly Male Cohort

    Oluwatosin A. Badejo

    2015-01-01

    Full Text Available Human Immunodeficiency Virus- (HIV- infected persons have a higher risk for acute myocardial infarction (AMI than HIV-uninfected persons. Earlier studies suggest that HIV viral load, CD4+ T-cell count, and antiretroviral therapy are associated with cardiovascular disease (CVD risk. Whether CD8+ T-cell count is associated with CVD risk is not clear. We investigated the association between CD8+ T-cell count and incident AMI in a cohort of 73,398 people (of which 97.3% were men enrolled in the U.S. Veterans Aging Cohort Study-Virtual Cohort (VACS-VC. Compared to uninfected people, HIV-infected people with high baseline CD8+ T-cell counts (>1065 cells/mm3 had increased AMI risk (adjusted HR=1.82, P<0.001, 95% CI: 1.46 to 2.28. There was evidence that the effect of CD8+ T-cell tertiles on AMI risk differed by CD4+ T-cell level: compared to uninfected people, HIV-infected people with CD4+ T-cell counts ≥200 cells/mm3 had increased AMI risk with high CD8+ T-cell count, while those with CD4+ T-cell counts <200 cells/mm3 had increased AMI risk with low CD8+ T-cell count. CD8+ T-cell counts may add additional AMI risk stratification information beyond that provided by CD4+ T-cell counts alone.

  7. Bone marrow transplantation in the rat. III. Structure of the liver inflammatory lesion in acute graft-versus-host disease

    The liver is a major parenchymal target organ of acute graft-versus-host disease (aGVHD) after bone marrow transplantation in the rat. The authors have analyzed the nature of cellular infiltrates in the liver using monoclonal antibodies against white cell subsets and investigated the anatomic distribution of the inflammatory cell subsets inside the liver parenchyma. Several types of white cells are present in a normal control liver: In the portal area the T-helper (Th) cells predominate, (surface) immunoglobulin-expressing B cells are present in ample numbers, and most of the phagocytes are Ia-positive. In the central vein area the T-suppressor/killer cells (Tsk) dominate, no B cells are present, and most of the phagocytes are Ia-negative. During aGVHD the number of T cells increases rapidly in the portal area; and after an initial strong increase, the Th/Tsk ratio decreases but remains still above 1. In the central vein area there is also an increase in the number of T cells, compared with that in the syngeneic recipient, but the Th/Tsk ratio rapidly decreases and remains uniformly below 1. During aGVHD the B cells entirely disappear from the portal area, whereas a small but distinct number of mature plasma cells with intracellular immunoglobulin appear in the central vein area. Following irradiation the Ia-positive phagocytic cells entirely disappear from the portal area and decrease distinctly in number in the central vein area. During aGVHD the number of Ia-positive phagocytes increases again in both locations. In the central vein area the positive phagocytes are seen over the background level, and, concomitantly, the Ia-negative phagocytes disappear

    2016-01-01

    Full Text Available Aim. To study gender and age characteristics of incidence rate, mortality and lethality in acute coronary heart disease (ACHD.Material and Methods. Analysis of the ACHD (ICD-10 codes: I21.0-I22.9, I20.0, I24 morbidity, mortality and lethality, depending on sex and age was performed in the population (n=285 736; 46% men of several city administrative districts of Voronezh, Ryazan and Khanty-Mansiysk. Morbidity, mortality and lethality were calculated on the basis of medical documentation as well as cases identified by the study protocol.Results. The ACHD morbidity and mortality in men were 1.99 and 1.79 times higher (p<0,001, respectively, than these in women. The studied parameters increase with age, reaching a maximum in 50-59 y.o., have a plateau in 60-79 y.o. and then they decrease. Morbidity and mortality in women increase with age, but reach a maximum in 70-79 y.o., being comparable with the male level, and then exceed it in ≥80 y.o. Age curve of lethality in men has J-alike shape with minimum in patients of 50-79 y.o. Women have a line age curve with minimum in patients of <50 y.o.Conclusion. The population of ACHD patients should be considered according to both the sex and age: <50, 50-79 and ≥80 y.o. Every of these population group has special epidemiological characteristics.

  9. The Role of M2 Macrophages in the Progression of Chronic Kidney Disease following Acute Kidney Injury.

    Myung-Gyu Kim

    Full Text Available Acute kidney injury (AKI is a major risk factor in the development of chronic kidney disease (CKD. However, the mechanisms linking AKI to CKD remain unclear. We examined the alteration of macrophage phenotypes during an extended recovery period following ischemia/reperfusion injury (IRI and determine their roles in the development of fibrosis.The left renal pedicle of mice was clamped for 40 min. To deplete monocyte/macrophage, liposome clodronate was injected or CD11b-DTR and CD11c-DTR transgenic mice were used.Throughout the phase of IRI recovery, M2-phenotype macrophages made up the predominant macrophage subset. On day 28, renal fibrosis was clearly shown with increased type IV collagen and TGF-β. The depletion of macrophages induced by the liposome clodronate injection improved renal fibrosis with a reduction of kidney IL-6, type IV collagen, and TGF-β levels. Additionally, the adoptive transfer of the M2c macrophages partially reversed the beneficial effect of macrophage depletion, whereas the adoptive transfer of the M1 macrophages did not. M2 macrophages isolated from the kidneys during the recovery phase expressed 2.5 fold higher levels of TGF-β than the M1 macrophages. The injection of the diphtheria toxin into CD11b or CD11c-DTR transgenic mice resulted in lesser depletion or no change in M2 macrophages and had little impact on renal fibrosis.Although M2 macrophages are known to be indispensible for short-term recovery, they are thought to be main culprit in the development of renal fibrosis following IRI.

    Although curcumin can increase the effectiveness of drugs against malaria, combination therapies using the molecule have never been investigated in Chagas disease (ChD). Therefore, we evaluated the efficacy of curcumin as a complementary strategy to benznidazole (Bz)-based chemotherapy in mice acutely infected with Trypanosoma cruzi Eighty-four 12-week-old Swiss mice were equally randomized into seven groups: uninfected (NI), T. cruzi infected and untreated (INF), infected and treated with 100 mg/kg of body weight Bz (B100), 50 mg/kg Bz (B50), 100 mg/kg curcumin (C100), 100 mg/kg Bz plus 100 mg/kg curcumin (B100 plus C100), and 50 mg/kg Bz plus 100 mg/kg curcumin (B50 plus C100). After microscopic identification of blood trypomastigotes (4 days after inoculation), both drugs were administered by gavage once a day for 20 days. Curcumin showed limited antiparasitic, anti-inflammatory, and antioxidant effects when administered alone. When curcumin and Bz were combined, there was a drastic reduction in parasitemia, parasite load, mortality, anti-T. cruzi IgG reactivity, circulating levels of cytokines (gamma interferon [IFN-γ], interleukin 4 [IL-4], and MIP1-α), myocardial inflammation, and morphological and oxidative cardiac injury; these results exceeded the isolated effects of Bz. The combination of Bz and curcumin was also effective at mitigating liver toxicity triggered by Bz, increasing the parasitological cure rate, and preventing infection recrudescence in noncured animals, even when the animals were treated with 50% of the recommended therapeutic dose of Bz. By limiting the toxic effects of Bz and enhancing its antiparasitic efficiency, the combination of the drug with curcumin may be a relevant therapeutic strategy that is possibly better tolerated in ChD treatment than Bz-based monotherapy.

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

    Fatoumata Diene Sarr

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

  12. Use of a care bundle in the emergency department for acute exacerbations of chronic obstructive pulmonary disease: a feasibility study.

    McCarthy, Cormac

    2013-01-01

    Aim: To determine the efficacy and usefulness of a chronic obstructive pulmonary disease (COPD) care bundle designed for the initial management of acute exacerbations of COPD and to assess whether it improves quality of care and provides better outcomes. Introduction: The level of care provided in the emergency department (ED) for COPD exacerbations varies greatly, and there is a need for a more systematic, consistent, evidence-based quality improvement approach to improve outcomes and costs. Methods: A prospective before and after study was carried out in a university teaching hospital. Fifty consecutive patients were identified in the ED with COPD exacerbations and their management was reviewed. Following the education of ED staff and the implementation of a COPD care bundle, the outcome for 51 consecutive patients was analyzed. This COPD care bundle consisted of ten elements considered essential to the management of COPD exacerbations and was scored 0–10 according to the number of items on the checklist implemented correctly. Results: Following implementation, the mean bundle score out of 10 improved from 4.6 to 7 (P,0.001). There was a significant decrease in the unnecessary use of intravenous corticosteroids from 60% to 32% (P=0.003) and also a marked improvement in the use of oxygen therapy, with appropriate treatment increasing from 76% to 96% (P=0.003). Prophylaxis for venous thromboembolism also improved from 54% to 73% (P=0.054). The 30-day readmission rate did not significantly improve. Conclusion: The use of a bundle improves the delivery of care for COPD exacerbations in the ED. There is more appropriate use of therapeutic interventions, especially oxygen therapy and intravenous corticosteroids.

    2010-10-01

    Full Text Available Abstract Background Acute ischaemic stroke is associated with alteration in systemic markers of vascular function. We measured forearm vascular function (using forearm flow mediated dilatation to clarify whether recent acute ischaemic stroke/TIA is associated with impaired systemic vascular function. Methods Prospective case control study enrolling 17 patients with recent acute ischaemic stroke/TIA and 17 sex matched controls with stroke more than two years previously. Forearm vascular function was measured using flow medicated dilatation (FMD. Results Flow mediated dilatation was 6.0 ± 1.1% in acute stroke/TIA patients and 4.7 ± 1.0% among control subjects (p = 0.18. The mean paired difference in FMD between subjects with recent acute stroke and controls was 1.25% (95% CI -0.65, 3.14; p = 0.18. Endothelium independent dilatation was measured in six pairs of participants and was similar in acute stroke/TIA patients (22.6 ± 4.3% and control subjects (19.1 ± 2.6%; p = 0.43. Conclusions Despite the small size of this study, these data indicate that recent acute stroke is not necessarily associated with a clinically important reduction in FMD.

  14. The role of human adenoviruses type 41 in acute diarrheal disease in Minas Gerais after rotavirus vaccination

    2016-03-01

    Full Text Available Abstract Human adenovirus species F (HAdV-F type 40 and 41 are commonly associated with acute diarrheal disease (ADD across the world. Despite being the largest state in southeastern Brazil and having the second largest number of inhabitants, there is no information in the State of Minas Gerais regarding the role of HAdV-F in the etiology of ADD. This study was performed to determine the prevalence, to verify the epidemiological aspects of infection, and to characterize the strains of human adenoviruses (HAdV detected. A total of 377 diarrheal fecal samples were obtained between January 2007 and August 2011 from inpatient and outpatient children of age ranging from 0 to 12 years. All samples were previously tested for rotavirus, norovirus, and astrovirus, and 314 of 377 were negative. The viral DNA was extracted, amplified using the polymerase chain reaction and the HAdV-positive samples were sequenced and phylogenetically analyzed. Statistical analyses were performed using the Chi-square test (p < 0.05, considering two conditions: the total of samples tested (377 and the total of negative samples for the remaining viruses tested (314. The overall prevalence of HAdV was 12.47% (47/377; and in 76.60% (36/47 of the positive samples, this virus was the only infectious agent detected. The phylogenetic analysis of partial sequences of 32 positive samples revealed that they all clustered with the HAdV-F type 41. The statistical analysis showed that there was no correlation between the onset of the HAdV infection and the origin of the samples (inpatients or outpatients in the two conditions tested: the total of samples tested (p = 0.598 and the total of negative samples for the remaining viruses tested (p = 0.614. There was a significant association in the occurrence of infection in children aged 0–12 months for the condition 1 (p = 0.030 as well as condition 2 (p = 0.019. The occurrence of infections due to HAdV did not coincide with a pattern of

    Tumor necrosis factor alpha (TNF-alpha) plays an important role in the pathogenesis of chronic inflammatory diseases, i.e., rheumatoid arthritis (RA), ankylosing spondylitis (AS), Crohn's disease (CD), and ulcerative colitis (UC). Anti-TNF-alpha strategies are successfully used in their treatment. However, their effect on heart function is still uncertain. The objectives of the study were to examine the acute and long-term effect of infliximab on the heart morphology and function in patients with chronic inflammatory disorders. Thirty-one patients (21 men and 10 women) were included. Ten percent of them were diagnosed with RA, 22.5 % with AS, 22.5 % with CD, and 45 % with UC, respectively. N-terminal fragment of pro-brain natriuretic peptide (NT-proBNP) was measured before and immediately after infliximab administration at the beginning of the study and in the sixth and 12th months. Echocardiography was performed at baseline and in the sixth and 12th months. There was a significant increase in NT-proBNP after the first infliximab infusion (88.40 ± 14.09 vs. 95.24 ± 14.28 pg/ml, p = 0.0046) and similar response was detected after each infusion in the sixth and 12th months. Plasma NT-proBNP slightly but not significantly decreased (88.40 ± 14.09 vs. 81.74 ± 23.14 pg/ml, p = 0.583, and 88.40 ± 14.09 vs. 56.83 ± 17.77 pg/ml, p = 0.0576, in the sixth and 12th months, respectively). There were no significant changes in echocardiographic structural and functional parameters of the left ventricle during follow-up. Plasma NT-proBNP mildly but significantly increases immediately after infliximab infusion. However, long-term infliximab administration does not deteriorate both cardiac morphology and function.

    Thirteen recipients of HLA-haploidentical, DR compatible bone marrow (BM) and the corresponding BM donors were HLA-DP typed using primed lymphocyte typing (PLT). Severe acute GVHD (greater than or equal to grade 2) developed within 3 months after BM-transplantation in all of eight recipients of DP...... incompatible BM, but in none of five recipients of DP-compatible BM. This difference was highly significant (p less than 0.001, Fisher's exact test). Moreover, severe acute GVHD was significantly increased in recipients of haploidentical, DR compatible, but DP incompatible BM as compared to severe acute GVHD...... in 88 recipients of HLA-identical BM (p less than 0.0001). In contrast, there was no difference in acute GVHD between recipients of haploidentical, DR and DP compatible BM and recipients of HLA-identical BM. The data presented here provide strong evidence for the first time that HLA-DP antigens play...

    Full Text Available Background: Graft-versus-host disease is one of the major complications after allogenic bone marrow transplantation, but it is not easy to anticipate the onset. Cytokines released by type 1 T-helper cells are thought to play a pivotal role in acute graft-versus-host disease (aGVHD. The ability to predict the likely occurrence of graft-versus-host-disease (GVHD after BMT would be extremely valuable. By serially measuring serum levels of soluble IL-2 receptor (sIL-2R, IL-18 and following allogeneic bone marrow transplantation (BMT, we tried to define their relationship to aGVHD as complication of the transplantation and determine useful markers for aGVHD predictors. Materials and Methods: Serum sIL-2R, IL-18, and levels were measured by sandwich ELISA in 219 sera samples from 39 patients (with hematological disorders before and after allogeneic BMT and 28 controls. All patients received BMT from HLA-identical siblings. Results: 25 patients developed aGVHD and serum levels of sIL-2 R and IL-18 , in sera drawn before transplantation , in patients with acute graft-versus-host disease (aGVHD + , were increased in comparison of patients without acute graft-versus-host disease (aGVHD ¯ and control group and there wasn’t any significant differences in serum levels of sIL-2 R and IL-18 in aGVHD ¯ patients and controls. Serum level of IL-18, in aGVHD+ patients, was increased during day 3 - 24 after BMT, and there was a significant difference in patients with GVHD 0 – GVHD III. In majority of patients with acute GVHD (60 % , the peak levels of IL-18 and IL-2R was achieved on day 10 after BMT and the rise in sIL-2R and IL-18 preceded of clinical signs of GVHD (mean day 15 after BMT. Level of IL-18 in patients with aGVHD had strongly correlated with the severity of aGVHD on Day 10 after BMT. IL-18 level mean (before BMT, in patients who received Busulfan and Fludarabin to treat aGVHD, was lower than in patients who received Busulfan - Endoxan, or

  20. Donepezil, anti-Alzheimer's disease drug, prevents cardiac rupture during acute phase of myocardial infarction in mice.

    Mikihiko Arikawa

    Full Text Available BACKGROUND: We have previously demonstrated that the chronic intervention in the cholinergic system by donepezil, an acetylcholinesterase inhibitor, plays a beneficial role in suppressing long-term cardiac remodeling after myocardial infarction (MI. In comparison with such a chronic effect, however, the acute effect of donepezil during an acute phase of MI remains unclear. Noticing recent findings of a cholinergic mechanism for anti-inflammatory actions, we tested the hypothesis that donepezil attenuates an acute inflammatory tissue injury following MI. METHODS AND RESULTS: In isolated and activated macrophages, donepezil significantly reduced intra- and extracellular matrix metalloproteinase-9 (MMP-9. In mice with MI, despite the comparable values of heart rate and blood pressure, the donepezil-treated group showed a significantly lower incidence of cardiac rupture than the untreated group during the acute phase of MI. Immunohistochemistry revealed that MMP-9 was localized at the infarct area where a large number of inflammatory cells including macrophages infiltrated, and the expression and the enzymatic activity of MMP-9 at the left ventricular infarct area was significantly reduced in the donepezil-treated group. CONCLUSION: The present study suggests that donepezil inhibits the MMP-9-related acute inflammatory tissue injury in the infarcted myocardium, thereby reduces the risk of left ventricular free wall rupture during the acute phase of MI.
