    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.

    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."

    Acute diarrhoeal diseases rank second amongst all infectious diseases as a killer in children below 5 years of age worldwide. Globally, 1.3 billion episodes occur annually, with an average of 2-3 episodes per child per year. The important aetiologic agents of diarrhoea and the guidelines for management are discussed. Management of acute diarrhoea is entirely based on clinical presentation of the cases. It includes assessment of the degree of dehydration clinically, rehydration therapy, feeding during diarrhoea, use of antibiotic(s) in selected cases, micronutrient supplementation and use of probiotics. Assessment of the degree of dehydration should be done following the WHO guidelines. Dehydration can be managed with oral rehydration salt (ORS) solution or intravenous fluids. Recently WHO has recommended a hypo-osmolar ORS solution for the treatment of all cases of acute diarrhoea including cholera. Feeding during and after diarrhoea (for at least 2-3 weeks) prevents malnutrition and growth retardation. Antibiotic therapy is not recommended for the treatmentof diarrhoea routinely. Only cases of severe cholera and bloody diarrhoea (presumably shigellosis) should be treated with a suitable antibiotic. Pilot studies in several countries have shown that zinc supplementation during diarrhoea reduces the severity and duration of the disease as well as antidiarrhoeal and antimicrobial use rate. Probiotics may offer a safe intervention in acute infectious diarrhoea to reduce the duration and severity of the illness.

    Full Text Available Background. Diarrhoeal disease (DD is a major cause of childhood mortality in developing countries. In South Africa (SA, it ranks as one of the top five causes of under-5 mortality. Local and global guidelines on the management of acute DD are readily available. The Standard Treatment Guidelines (STGs and Essential Drugs List for Hospital Level Paediatrics are a recognised standard of care for children in SA hospitals. However, children still die from this preventable disease. Objective. To determine whether doctors adhered to standard treatment guidelines when treating children under 5 years of age presenting to Edendale Hospital in Pietermaritzburg, KwaZulu-Natal Province, with acute DD. Methods. The study was a retrospective clinical audit of individual patient records. Results. One hundred and thirty-five patient records were reviewed. Forty-seven percent had a correct nutritional assessment, 41% were correctly assessed for shock and 27% for dehydration. Appropriate investigations were undertaken in 12%. Ninety-seven percent of patients had appropriate fluid plans prescribed. Zinc was prescribed in only 39% of patients, whereas 84% were appropriately not prescribed antibiotics and no patients received anti-diarrhoeal medication. In 90% of patients, the correct post-care patient referral was made, and 47% of caregivers were adequately advised about ongoing care of their children. Conclusion. This study identifies substantial non-adherence to the SA STGs for the management of young children with acute DD.

Cholera is an acute diarrhoeal infection caused by ingestion of food or water contaminated with the bacterium Vibrio Cholerae. Objectives: 1. To document the factors responsible for the outbreak. 2. To provide recommendations for prevention and control of such outbreaks in future. Methods: After receiving verbal information from district office regarding outbreak of diarrhoeal disease (cholera in a town of Bijapur district, we independently conducted a cross sectional study in the affected area and collected information regarding no. of people affected since the outbreak, their age and sex distribution. A total of 3802 people were interviewed using a predesigned questionnaire on 28th and 29th July, 2012. We also conducted environmental investigation regarding the source of contamination and collected 2 water samples from drinking water source. Results: All the cases were clustered in the five streets, which were consuming water from contaminated two water tanks. A total of 121 cases of diarrhoea were identified affecting 3.18% of the population. Attack rate of cholera was highest (4.5% in 25-34 years age group followed by 4.22% in 15-24 years age group. Attack rates was higher among females (3.4% compared to males (2.9%. Laboratory report stated that water samples were unfit for drinking purpose. V. Cholera (Ogawa serotype was isolated from water sample. Conclusion: Consumption of contaminated water from a newly dug bore-well had led to the diarrhea outbreak. Lack of sanitation and hygiene had worsened the situation.

    Persea americana is a plant used by traditional medicine practitioners to treat ailments including diarrhoea and diabetes mellitus in Nigeria. Hence, the chloroform and the methanol fractions of the chloroform-methanol extract of the leaves of P. americana were evaluated for their acute toxicity as well as anti-diarrhoeal effects in Wistar rats to substantiate this claim. The chloroform and methanol fractions [at graded doses of 100 and 200 mg/Kg body weight (b.w) of each] were studied for their anti-diarrhoeal effects in terms of the reductions in the wetness of faeces and the frequency of defaecation of castor oil-induced diarrhoea. To understand the mechanism of their anti-diarrhoeal effects, their actions were further evaluated on castor oil-induced enteropooling (intestinal fluid accumulation). The median lethal dose (LD50) of the methanol fraction was found to be less than 5000 mg/Kg b.w. At the two doses, the chloroform and the methanol fractions showed dose-dependent significant (p americana possesses significant anti-diarrhoeal effect and may be a potent source of anti-diarrhoeal drug(s) in future.

    Background Climate change has begun to negatively affect human health, with larger burdens projected in the future as weather patterns continue to change. The climate change-related health consequences of diarrhoeal diseases, malnutrition, and malaria are projected to pose the largest risks to future populations. Limited work has been done to estimate the costs of adapting to these additional health burdens. Methods The costs of treating diarrhoeal diseases, malnutrition (stunting and wasting only), and malaria in 2030 were estimated under three climate scenarios using (1) the current numbers of cases; (2) the projected relative risks of these diseases in 2030; and (3) current treatment costs. The analysis assumed that the number of annual cases and costs of treatment would remain constant. There was limited consideration of socioeconomic development. Results Under a scenario assuming emissions reductions resulting in stabilization at 750 ppm CO2 equivalent in 2210, the costs of treating diarrhoeal diseases, malnutrition, and malaria in 2030 were estimated to be $4 to 12 billion. This is almost as much as current total annual overseas development assistance for health. Conclusion The investment needs in the health sector to address climate-sensitive health outcomes are large. Additional human and financial resources will be needed to prevent and control the projected increased burden of health outcomes due to climate change. PMID:18803827

    Studies of temporal and spatial patterns of diarrhoeal disease can suggest putative aetiological agents and environmental or socioeconomic drivers. Here, the seasonal patterns of monthly acute diarrhoeal morbidity in Thailand, where diarrhoeal morbidity is increasing, are explored. Climatic data (2003-2006) and Thai Ministry of Health annual reports (2003-2009) were used to construct a spatially weighted panel regression model. Seasonal patterns of diarrhoeal disease were generally bimodal with aetiological agents peaking at different times of the year. There is a strong association between daily mean temperature and precipitation and the incidence of hospitalization due to acute diarrhoea in Thailand leading to a distinct spatial pattern in the seasonal pattern of diarrhoea. Model performance varied across the country in relation to per capita GDP and population density. While climatic factors are likely to drive the general pattern of diarrhoeal disease in Thailand, the seasonality of diarrhoeal disease is dampened in affluent urban populations.

  16. The global burden of childhood coeliac disease: a neglected component of diarrhoeal mortality?

    Directory of Open Access Journals (Sweden)

    Peter Byass

    Full Text Available OBJECTIVES: Coeliac disease has emerged as an increasingly recognised public health problem over the last half-century, and is now coming to be seen as a global phenomenon, despite a profound lack of globally representative epidemiological data. Since children with coeliac disease commonly present with chronic diarrhoea and malnutrition, diagnosis is often overlooked, particularly in poorer settings where children often fail to thrive and water-borne infectious diarrhoeas are common. This is the first attempt to make global estimates of the burden of coeliac disease in childhood. METHODS: We built a relatively crude model of childhood coeliac disease, incorporating estimates of population prevalence, probability of non-diagnosis, and likelihood of mortality among the undiagnosed across all countries from 1970 to 2010, based around the few available data. All our assumptions are stated in the paper and the model is available as a supplementary file. FINDINGS: Our model suggests that in 2010 there were around 2.2 million children under 5 years of age living with coeliac disease. Among these children there could be 42,000 deaths related to coeliac disease annually. In 2008, deaths related to coeliac disease probably accounted for approximately 4% of all childhood diarrhoeal mortality. CONCLUSIONS: Although coeliac disease may only account for a small proportion of diarrhoeal mortality, these deaths are not preventable by applying normal diarrhoea treatment guidelines, which may even involve gluten-based food supplements. As other causes of diarrhoeal mortality decline, coeliac disease will become a proportionately increasing problem unless consideration is given to trying gluten-free diets for children with chronic diarrhoea and malnutrition.

    Full Text Available Background: Global, regional and national estimates clearly place diarrhoeal diseases as a major, albeit to an extant neglected public health problem. Deaths of children aged <5 years owing to diarrhoea was estimated to be 1.87 million at the global level (uncertainty range from 1.56 to 2.19 million, which is approximately 19% of total child deaths. Objectives: The present report is a cross-sectional study undertaken to estimate the role of various aetiological agents causing diarrhoea in North Karnataka and adjoining areas of Maharashtra and Goa. Methods: Three hundred stool samples were collected from patients seeking health care at KLES Dr. Prabhakar Kore Hospital and Medical Research Centre, Belgaum; and processed for detection of various bacterial, viral and parasitic agents. Results: Bacterial pathogens attributed to 65.7% of diarrhoea cases, followed by viral infection (22%, parasitic infection (16.3% and infection by Candida spp. (5.6%. The study identified Escherichia coli in general and Enteropathogenic E. coli in particular, and Group A Rotavirus to be the most frequently isolated pathogens among diarrhoea patients. Conclusion: The data generated from the current study will help the health officials for better interventional and treatment strategies for diarrhoeal diseases.

    As primary caregiver to under-five children in Ethiopia, mothers' knowledge, perception, and management skills are important to minimize the effects of morbidity and mortality associated with diarrhoeal diseases. A community-based comparative cross-sectional study was conducted in Abramo and Megele 37 kebeles (the last administration division) in Assosa district of western Ethiopia in July 2010. Quantitative data were obtained by a structured questionnaire from 232 randomly-selected mothers having children aged less than five years regarding their knowledge, perception, and management. Qualitative data were also collected by arranging four focus group discussions involving mothers from the two communities. The prevalence of diarrhoeal diseases among under-five children was 33.2%, and the knowledge of mothers about the causes, transmission, and prevention of diarrhoea in the study area was 37.5%. The prevalence of diarrhoeal disease was higher in the settlement area whereas mothers' knowledge was better in the indigenous community; 62.9% of mothers were categorized as having good attitude on causes, transmission, and prevention of diarrhoeal disease. Community water source, water storage container, and knowledge of mothers remained a strong predictor of diarrhoeal morbidity after conducting logistic regression analysis (OR=8.4, CI 3.59-31.85; OR=2.2, CI 1.02-4.89; and OR=3.62, CI 1.23-4.71 respectively). Diarrhoeal morbidity was high in the study areas. On the contrary, knowledge and attitude of mothers, recognizing the danger sign of dehydration due to diarrhoea, and the prevention and management of childhood diarrhoeal diseases were not adequate. Information, education and communication strategy may help increase the knowledge and create positive attitude among mothers regarding the cause, prevention, and management of diarrhoea.

    The accurate microbiological diagnosis of diarrhoea involves numerous laboratory tests and, often, the pathogen is not identified in time to guide clinical management. With next-generation sequencing (NGS) becoming cheaper, it has huge potential in routine diagnostics. The aim of this study was to evaluate the potential of NGS-based diagnostics through direct sequencing of faecal samples. Fifty-eight clinical faecal samples were obtained from patients with diarrhoea as part of the routine diagnostics at Hvidovre University Hospital, Denmark. Ten samples from healthy individuals were also included. DNA was extracted from faecal samples and sequenced on the Illumina MiSeq system. Species distribution was determined with MGmapper and NGS-based diagnostic prediction was performed based on the relative abundance of pathogenic bacteria and Giardia and detection of pathogen-specific virulence genes. NGS-based diagnostic results were compared to conventional findings for 55 of the diarrhoeal samples; 38 conventionally positive for bacterial pathogens, two positive for Giardia, four positive for virus and 11 conventionally negative. The NGS-based approach enabled detection of the same bacterial pathogens as the classical approach in 34 of the 38 conventionally positive bacterial samples and predicted the responsible pathogens in five of the 11 conventionally negative samples. Overall, the NGS-based approach enabled pathogen detection comparable to conventional diagnostics and the approach has potential to be extended for the detection of all pathogens. At present, however, this approach is too expensive and time-consuming for routine diagnostics.

    Full Text Available Countries in Latin America were among the first to implement routine vaccination against species A rotavirus (RVA. We evaluate data from Latin America on reductions in gastroenteritis and RVA disease burden following the introduction of RVA vaccine. Published literature was reviewed to identify case-control studies of vaccine effectiveness and population-based studies examining longitudinal trends of diarrhoeal disease reduction after RVA vaccine introduction in Latin American countries. RVA vaccine effectiveness and impact on gastroenteritis mortality and hospitalization rates and RVA hospitalization rates are described. Among middle-income Latin American countries with published data (Mexico, Brazil, El Salvador and Panama, RVA vaccine contributed to a gastroenteritis-associated mortality reduction of 22-41%, a gastroenteritis-associated hospitalization reduction of 17-51% and a RVA hospitalization reduction of 59-81% among children younger than five years of age. In Brazil and El Salvador, case-control studies demonstrated that a full RVA vaccination schedule was 76-85% effective against RVA hospitalization; a lower effectiveness of 46% was seen in Nicaragua, the only low-income country with available data. A growing body of literature offers convincing evidence of "real world" vaccine program successes in Latin American settings, which may be expanded as more countries in the region include RVA vaccine in their immunization programs.

The study period was divided into three stages; the first pre-dated the widespread application of oral rehydration therapy (ORT); the second, covered the implementation of a nationwide programme promoting ORT; and the third included additional measures, such as immunization and improvements in basic sanitation. Mortality rates decreased progressively, at an average of 1.8% per year in the first stage, 6.4% in the second, and 17.8% in the third. The importance of literacy campaigns for women and the promotion of ORT was confirmed. Both of these measures reduced mortality; however, a greater reduction resulted from a massive immunization campaign against measles and improvements in sanitation (expansion of the drainage and piped water systems, improved water chlorination procedure, and effective prohibition of the use of sanitary sewage for vegetable irrigation).

Two hundred and twenty pairs of children, matched on age, were recruited as cases and controls over a period of 5 months in Ibadan. Questionnaire and observation checklist were used to obtain information on hygiene practices from caregivers/mothers and sanitation conditions in the households of 30% of the consenting mothers/caregivers. Data were analysed using descriptive and inferential statistics. Caregivers/mothers' mean ages were 31.3 ±7.5 (cases) and 30.6 ±6.0(controls) years. The risk of diarrhoea was significantly higher among children whose mothers did not wash hands with soap before food preparation (OR=3.0, pHygiene and sanitation conditions within households were risk factors for diarrhoea. This study revealed the feasibility of developing and implementing an adequate model to establish intervention priorities in sanitation in Ibadan, Nigeria.

    Although sapovirus (SaV) has been detected in 2.2-12.7% of gastroenteritis cases globally, there are limited data on SaV epidemiology. Describe the epidemiology, clinical characteristics and factors associated with SaV gastroenteritis in hospitalised children Sapoviruses were detected in 7.7% (238/3103) of children admitted to hospital and 11.4% (9/79) of deaths. Sapovirus was detected more commonly in children 19-24 months compared toSapoviruses, which are perceived to cause mild diarrhoea, were detected in hospitalised children and diarrhoeal deaths in South Africa. Determinants increasing the odds of SaV included overcrowding and concomitant infections while HIV-infected children with SaV displayed bloody stools, low birth weight and reduced access to proper sanitation. Mitigation strategies against SaV infections include improved sanitation. Copyright © 2016 Elsevier B.V. All rights reserved.

    A major health consequence of rapid population growth in urban areas is the increased pressure on existing overstretched water and sanitation services. This study of an expanding periurban neighbourhood of Yangon Region, Myanmar, aimed to ascertain the prevalence of acute diarrhoea in children under 5 years; to identify household sources of drinking-water; to describe purification and storage practices; and to assess drinking-water contamination at point-of-use. A survey of the prevalence of acute diarrhoea in children under 5 years was done in 211 households in February 2013; demographic data were also collected, along with data and details of sources of drinking water, water purification, storage practices and waste disposal. During March-August, a subset of 112 households was revisited to collect drinking water samples. The samples were analysed by the multiple tube fermentation method to count thermotolerant (faecal) coliforms and there was a qualitative determination of the presence of Escherichia coli. Acute diarrhoea in children under 5 years was reported in 4.74% (10/211, 95% CI: 3.0-9.0) of households within the past two weeks. More than half of the households used insanitary pit latrines and 36% disposed of their waste into nearby streams and ponds. Improved sources of drinking water were used, mainly the unchlorinated ward reservoir, a chlorinated tube well or purified bottled water. Nearly a quarter of households never used any method for drinking-water purification. Ninety-four per cent (105/112) of water samples were contaminated with thermotolerant (faecal) coliforms, ranging from 2.2 colony-forming units (CFU)/100 mL (21.4%) to more than 1000 CFU/100 mL (60.7%). Of faecal (thermotolerant)-coliform-positive water samples, 70% (47/68) grew E. coli. The prevalence of acute diarrhoea reported for children under 5 years was high and a high level of drinking-water contamination was detected, though it was unclear whether this was due to contamination at

    Diarrhoeal diseases are a common cause of morbidity and are associated with mortality in HIV-infected populations. Little is known about the contribution of clinical and socio-environmental factors to the risk of diarrhoea in these populations in rural sub-Saharan Africa. We conducted a case-control study of people attending a rural HIV clinic with an episode of diarrhoea in Bushbuckridge, South Africa. Cases were defined as HIV-positive adults with symptoms of diarrhoea before or after initiation of antiretroviral therapy (ART). Controls without diarrhoea were randomly selected from clinic attendees. Structured questionnaires and case-file reviews were undertaken to describe clinical and socioenvironmental risk factors. We recruited 103 cases of diarrhoea from 121 patients meeting case definitions. Cases were more likely to be women (P = 0.013), aged over 45 years (P = 0.002), divorced or separated (P = 0.006), have limited formal education (P = 0.003), have inadequate access to sanitation facilities (P = 0.045), have water access limited to less than three days per week (P = 0.032) and not yet initiated on ART (P analysis, diarrhoea remained associated with female gender (adjusted odds ratio [aOR]: 2.02, 95% CI 1.10-3.73), older age (aOR: 6.31, 95% CI 1.50-26.50), limited access to water (aOR: 2.66, 95% CI 1.32-5.35) and pre-ART status (aOR: 5.87, 95% CI 3.05-11.27). Clinical and socio-environmental factors are associated with occurrence of diarrhoeal disease among rural HIV patients in South Africa. Further intervention research is urgently needed, combining community- and clinic-based approaches, to improve access to water, sanitation and ART for rural areas with high HIV prevalence, along with structural interventions to address gender inequities.

    Full Text Available Introduction: Kenya is home to over 400 000 refugees from neighbouring countries. There is scanty information about diarrhoea amongst urban refugees in Kenya.Objectives: We investigated the enteric bacteria causing diarrhoea amongst urban refugee children and described the associated factors.Method: During the period of August–December 2010, urban refugee children between the ages of two and five who attended Eastleigh County Council Health Centre were enrolled into the study. Diarrhoeal cases were compared with age-matched children with no diarrhoea (controls. Stool specimens were collected and enteric bacteria isolated. A questionnaire was administered to identify risk factors.Results: A total of 41 cases and 41 controls were enrolled in the study. The age and country of origin were similar for cases and controls. The bacterial isolation rates amongst the cases were: non-pathogenic Escherichia coli 71%, Shigella dysenteriae 2.4%, Shigella flexneri 2.4%, Salmonella paratyphi 5%. For the controls, non-pathogenic E. coli 90% and enterotoxigenic E. coli (ETEC2.4% were amongst the organisms isolated. All isolates were resistant to amoxicillin; resistance to other antibiotics varied by isolate type. Factors associated independently with diarrhoea included children not washing their hands with soap (aOR 5.9, p < 0.05, neighbour(s having diarrhoea (aOR 39.8, p < 0.05, children not exclusively breastfed for their first 6 months (aOR 7.6, p < 0.05 and children eating food cooked the previous day (aOR 23.8, p = 0.002.Conclusions: Shigella species, Salmonella species and ETEC were found to be responsible for diarrhoea amongst the urban refugee children. Measures to control and guide the use of antibiotics are critical for the prevention of antibiotic resistance. Efforts to improve personal and domestic hygiene, including educational campaigns to promote appropriate handwashing, should be encouraged.

  12. How effective is good domestic kitchen hygiene at reducing diarrhoeal disease in developed countries? A systematic review and reanalysis of the UK IID study

    2008-02-01

    Full Text Available Abstract Background To assess whether domestic kitchen hygiene is an important contributor to the development of diarrhoea in the developed world. Methods Electronic searches were carried out in October 2006 in EMBASE, MEDLINE, Web of Knowledge, Cochrane central register of clinical trials and CINAHL. All publications, irrespective of study design, assessing food hygiene practices with an outcome measure of diarrhoea were included in the review. All included studies underwent data extraction and the data was subsequently analysed. The analysis was conducted by qualitative synthesis of the results. Given the substantial heterogeneity in study design and outcome measures meta-analysis was not done. In addition the existing dataset of the UK IID study was reanalysed to investigate possible associations between self-reported diarrhoea and variables indicative of poor domestic kitchen hygiene Results Some 14 studies were finally included in subsequent analyses. Of the 14 studies included in this systematic review, 11 were case-control studies, 2 cross-sectional surveys, and 1 RCT. Very few studies identified any significant association with good environmental kitchen hygiene. Although some of the variables in the reanalysis of the UK IID study were statistically significant no obvious trend was seen. Conclusion The balance of the available evidence does not support the hypothesis that poor domestic kitchen hygiene practices are important risk factors for diarrhoeal disease in developed countries.

    Diarrheagenic Escherichia coli (DEC) cause acute and persistent diarrhoea worldwide, but little is known about their epidemiology in Mexico. We determined the prevalence of bacterial enteropathogens in 831 children with acute diarrhoea over a four-year period in Yucatan, Mexico. Six DEC supplementary virulence genes (SVG), mainly associated with enteroaggregative E. coli (EAEC), were sought in 3100 E. coli isolates. DEC was the most common bacterial enteropathogen (28%), surpassing Salmonella (12%) and Shigella (9%). Predominant DEC groups were diffusely adherent E. coli (DAEC) (35%), EAEC (24%), and enteropathogenic E. coli (EPEC) (19%). Among children with DEC infections, 14% had severe illness mainly caused by EPEC (26%) and DAEC (18%); 30% had moderate diarrhoea mainly caused by DAEC (36%), mixed DEC infections (33%) and EAEC (32%). DAEC was most prevalent during spring, while ETEC, EAEC and EPEC predominated in summer. EAEC was more frequent in children 6-24 months old than in those younger than 6 months of age (P = 0.008, OR = 4.2, 95% CI, 1.3-13.9). The presence of SVG dispersin, (aatA), dispersin-translocator (aatA), enteroaggregative heat-stable toxin 1 (astA), plasmid encoded toxin (pet), cytolethal distending toxin (cdt) was higher in DEC than non-DEC strains, (36% vs 26%, P DAEC patients had strains with SVG. 54% of EPEC patients carried pet-positive strains alone or in combination with astA; only this DEC group harboured cdt-positive isolates. All ETEC patients carried astA- or astA-aap-positive strains. astA and aap were the most common SVG in DAEC (3% and 2%) and non-DEC strains (21% and 13%). DEC carrying SVG are an important cause of moderate to severe bacterial diarrhoea in Mexican children.

    Full Text Available Research question: 1. Will measles vaccination reduce the incidence and during of diarrhoeal episodes in children? 2. Will measles vaccination reduce the morbidity load because of diarrhoea? Objectives: 1. To provide measles immunization to rural children 9 to 24 months of age. 2. to study the occurrence of diarrhoeal episodes by domicillary visits every month for a period of 1 year. Design: Longitudinal study. Setting: Rural area in the state of Haryana. Participants: Children between the ages of 9 and 24 months with parental informed consent. Study variables: diarrhoeal episodes per child/year, duration of diarrhoea. Outcome Variable: the difference between the two groups (immunized and non- immunized of attack rate and duration of diarrhoeal episodes. Statistical Analysis: Chi square test. Results: immunization coverage was 75%. Attack rates of diarrhoea in immunized children (1.6/child/year was no different to that in the non- immunized (1.5/child/year. The mean duration of diarrhoea in both groups was 2.3 days. The prevalence diarrhoea in immunized and non-immunized was 3.85 and 3.67 respectively. Conclusion: Measles vaccination has no impact on diarrhoeal morbidity.

    Objective Diarrhoea is a significant contributer to morbidity and is among the leading causes of death of children living in poverty. As such, the incidence, duration and severity of diarrhoeal episodes in the household are often key variables of interest in a variety of community-based studies. However, there currently exists no means of defining diarrhoeal severity that are (A) specifically designed and adapted for community-based studies, (B) associated with poorer child outcomes and (C) agreed on by the majority of researchers. Clinical severity scores do exist and are used in healthcare settings, but these tend to focus on relatively moderate-to-severe dehydrating and dysenteric disease, require trained observation of the child and, given the variability of access and utilisation of healthcare, fail to sufficiently describe the spectrum of disease in the community setting. Design Longitudinal cohort study. Setting Santa Clara de Nanay, a rural community in the Northern Peruvian Amazon. Participants 442 infants and children 0–72 months of age. Main outcome measures Change in weight over 1-month intervals and change in length/height over 9-month intervals. Results Diarrhoeal episodes with symptoms of fever, anorexia, vomiting, greater number of liquid stools per day and greater number of total stools per day were associated with poorer weight gain compared with episodes without these symptoms. An instrument to measure the severity was constructed based on the duration of these symptoms over the course of a diarrhoeal episode. Conclusions In order to address limitations of existing diarrhoeal severity scores in the context of community-based studies, we propose an instrument comprised of diarrhoea-associated symptoms easily measured by community health workers and based on the association of these symptoms with poorer child growth. This instrument can be used to test the impact of interventions on the burden of diarrhoeal disease. PMID:24907244

  1. Acute graft versus host disease

    Vogelsang Georgia B

    2007-09-01

    Full Text Available Abstract Acute graft-versus-host disease (GVHD occurs after allogeneic hematopoietic stem cell transplant and is a reaction of donor immune cells against host tissues. Activated donor T cells damage host epithelial cells after an inflammatory cascade that begins with the preparative regimen. About 35%–50% of hematopoietic stem cell transplant (HSCT recipients will develop acute GVHD. The exact risk is dependent on the stem cell source, age of the patient, conditioning, and GVHD prophylaxis used. Given the number of transplants performed, we can expect about 5500 patients/year to develop acute GVHD. Patients can have involvement of three organs: skin (rash/dermatitis, liver (hepatitis/jaundice, and gastrointestinal tract (abdominal pain/diarrhea. One or more organs may be involved. GVHD is a clinical diagnosis that may be supported with appropriate biopsies. The reason to pursue a tissue biopsy is to help differentiate from other diagnoses which may mimic GVHD, such as viral infection (hepatitis, colitis or drug reaction (causing skin rash. Acute GVHD is staged and graded (grade 0-IV by the number and extent of organ involvement. Patients with grade III/IV acute GVHD tend to have a poor outcome. Generally the patient is treated by optimizing their immunosuppression and adding methylprednisolone. About 50% of patients will have a solid response to methylprednisolone. If patients progress after 3 days or are not improved after 7 days, they will get salvage (second-line immunosuppressive therapy for which there is currently no standard-of-care. Well-organized clinical trials are imperative to better define second-line therapies for this disease. Additional management issues are attention to wound infections in skin GVHD and fluid/nutrition management in gastrointestinal GVHD. About 50% of patients with acute GVHD will eventually have manifestations of chronic GVHD.

    Microbial infections and resulting inflammation and oxidative stress are common pathogenesis of gastrointestinal tract (GIT) disorders. In South Africa, several species of the genus Maytenus are used in traditional medicine to treat various infectious diseases. Most of the previous work on this genus was focused on nonpolar extracts from the root and bark. In this study, leaf extracts of polar extracts of Maytenus peduncularis, Maytenus procumbens, Maytenus senegalensis and Maytenus undata were evaluated for antimicrobial, anti-inflammatory and antioxidant activities to determine their efficacy as therapeutic agents in GIT disorders. Phenolic-enriched leaf extracts and fractions were prepared by extracting with acidified 70% methanol and solvent-solvent fractionation. The activities of the fractions against Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli and Enterococcus faecalis as well as clinical isolates of Aspergillus fumigatus, Candida albicans and Cryptococcus neoformans were determined using a serial microplate dilution method. Antioxidant activities were determined using 1,1-diphenyl-2-picrylhydrazyl (DPPH), 2,2'-azinobis(3-ethylbenzthiazoline-6-sulphonic acid) (ABTS), hydroxyl (OH) radical scavenging and linoleic acid peroxidation inhibitory assays. The phenolic composition as well as the cytotoxicity against Vero cell lines of the crude extracts was evaluated using various standard protocols. The antimicrobial activities were concentrated in the non-polar fractions of hexane, dichloromethane and ethyl acetate (MICs 19-312 μg/ml). The crude extracts and polar fractions (butanol and water) had moderate to poor antimicrobial activity (MICs 312 to above 2500 μg/ml). The crude extracts and polar fractions had good antioxidant activity (EC50 values varied from 1.22 to 607 μg/ml, 1.71 to 312 μg/ml and 23 to 284 μg/ml for DPPH, ABTS and OH respectively. Linoleic acid peroxidation inhibition EC50 values of the crude extracts ranged between 27

    Inflammatory periodontal diseases are highly prevalent, although most of these diseases develop and progress slowly, often unnoticed by the affected individual. However, a subgroup of these diseases include aggressive and acute forms that have a relatively low prevalence but show a rapid-course, high rate of progression leading to severe destruction of the periodontal tissues, or cause systemic symptoms that often require urgent attention from healthcare providers. Aggressive periodontitis is an early-onset, destructive disease that shows a high rate of periodontal progression and distinctive clinical features. A contemporary case definition of this disease is presented. Population studies show that the disease is more prevalent in certain geographic regions and ethnic groups. Aggressive periodontitis is an infectious disease, and recent data show that in affected subjects the subgingival microbiota is composed of a mixed microbial infection, with a wide heterogeneity in the types and proportions of microorganisms recovered. Furthermore, there are significant differences in the microbiota of the disease among different geographic regions and ethnicities. There is also evidence that the Aggregatibacter actinomycetemycomitans-JP2 clone may play an important role in the development of the disease in certain populations. The host response plays an important role in the susceptibility to aggressive periodontitis, where the immune response may be complex and involve multiple mechanisms. Also, genetic factors seem to play an important role in the pathogenesis of this disease, but the mechanisms of increased susceptibility are complex and not yet fully understood. The available data suggest that aggressive periodontitis is caused by mutations either in a few major genes or in multiple small-effect genes, and there is also evidence of gene-gene and gene-environment interaction effects. Diagnostic methods for this disease, based on a specific microbiologic, immunologic or

  7. Acute exacerbations of fibrotic interstitial lung disease.

    Science.gov (United States)

    Churg, Andrew; Wright, Joanne L; Tazelaar, Henry D

    2011-03-01

    An acute exacerbation is the development of acute lung injury, usually resulting in acute respiratory distress syndrome, in a patient with a pre-existing fibrosing interstitial pneumonia. By definition, acute exacerbations are not caused by infection, heart failure, aspiration or drug reaction. Most patients with acute exacerbations have underlying usual interstitial pneumonia, either idiopathic or in association with a connective tissue disease, but the same process has been reported in patients with fibrotic non-specific interstitial pneumonia, fibrotic hypersensitivity pneumonitis, desquamative interstitial pneumonia and asbestosis. Occasionally an acute exacerbation is the initial manifestation of underlying interstitial lung disease. On biopsy, acute exacerbations appear as diffuse alveolar damage or bronchiolitis obliterans organizing pneumonia (BOOP) superimposed upon the fibrosing interstitial pneumonia. Biopsies may be extremely confusing, because the acute injury pattern can completely obscure the underlying disease; a useful clue is that diffuse alveolar damage and organizing pneumonia should not be associated with old dense fibrosis and peripheral honeycomb change. Consultation with radiology can also be extremely helpful, because the fibrosing disease may be evident on old or concurrent computed tomography scans. The aetiology of acute exacerbations is unknown, and the prognosis is poor; however, some patients survive with high-dose steroid therapy.

    Whether acute recurrent pancreaUtis is a chronic disease is still debated and a consensus is not still reached as demonstrated by differences in the classification of acute recurrent pancreatitis.There is major evidence for considering alcoholic pancreatitis as a chronic disease ab initio while chronic pancreatitis lesions detectable in biliary acute recurrent pancreatitis (ARP) seem a casual association.Cystic fibrosis transmembrane con ductance regulator (CFTR) gene mutation,hereditary and obstructive pancreatitis seem an acute disease that progress to chronic pancreatitis,likely as a consequence of the activation and proliferation of pancreatic stellate cells that produce and activate collagen and therefore fibrosis.From the diagnostic point of view,in patients with acute recurrent pancreatitis Endoscopic ultrasound (EUS) seems the more reliable technique for an accurate evaluation and follow-up of some ductal and parenchymal abnormalities suspected for early chronic pancreatitis.

    Full Text Available Diarrhoea is a major public health problem in developing countries and is said to be endemic in many regions of Asia. It is a leading cause of high degree of morbidity and mortality. The anti-diarrhoeal potential of the ethanolic extract of leaves of Mimosa pudica Linn (Mimosaceae has been evaluated using several experimental models in Wistar albino rats. The ethanolic extract inhibited castor oil induced diarrhoea and PGE2 induced enteropooling in rats and has also reduced gastrointestinal motility after charcoal meal administration. The ethanolic extract at 200 and 400 mg/kg was showed significantly inhibited diarrhoea. There was a significant (P<0.001 dose-dependent decrease in the diarrhoea produced by all the three models in rats as compared to the standard drug. The anti-diarrhoeal property may be related to the tannin and flavonoids present in the extract. These results clearly indicated that ethanolic extract of the leaves of Mimosa pudica is effective against diarrhoeal disease

    Many infections follow a seasonal trend. Aim of our study was to check whether acute pelvic inflammatory disease (PID) follows a seasonal progress. In a retrospective study on 12,152 hospital records, 158 cases of acute pelvic inflammatory disease were identified. Periodogram analysis was applied to the date of pelvic inflammatory disease admission and to related environmental factors, such as temperature and photoperiod. Pelvic inflammatory disease follows a seasonal rhythm with mean to peak variation of 23 % and maximal values in September (±37.2 days). The rhythm, more evident in married women, is related to the rhythm of temperature advanced by 2 months and of photoperiod advanced by 3 months. Cases of pelvic inflammatory disease are more frequent than expected in unmarried (36 vs. 17.3/34,626, p = 0.015), particularly divorced women 30-40 years of age. Our study evidences a seasonal trend and confirms unmarried, particularly divorced status, as important risk factor for acute pelvic inflammatory disease.

    Despite the progress that has been made in the treatment of cholera, mortality rates from this disease remain high in rural areas where intravenous fluids are not readily available. The authors have therefore conducted controlled studies into the efficacy of a simpler form of maintenance therapy-the administration of glucose-containing electrolyte solutions by mouth. The results obtained from the study of 51 adult patients (36 with cholera and 15 with severe non-cholera diarrhoea) indicate that oral fluids are adequate for maintenance therapy in cholera and severe diarrhoeal disease, and that there is no significant increase in the duration of diarrhoea or in the stool volume in patients receiving such therapy.The addition of a non-specific adsorbent, charcoal, to the fluid led to a significant increase in the volume of diarrhoeal stools and to prolongation of vibrio excretion; its use is therefore not recommended. The use of oral replacement solutions should result in improvement of cholera treatment of adults in rural areas and in a reduction in the cost of treatment.

  17. Treatment of Acute Pelvic Inflammatory Disease

    2011-01-01

    Full Text Available Pelvic inflammatory disease (PID, one of the most common infections in nonpregnant women of reproductive age, remains an important public health problem. It is associated with major long-term sequelae, including tubal factor infertility, ectopic pregnancy, and chronic pelvic pain. In addition, treatment of acute PID and its complications incurs substantial health care costs. Prevention of these long-term sequelae is dependent upon development of treatment strategies based on knowledge of the microbiologic etiology of acute PID. It is well accepted that acute PID is a polymicrobic infection. The sexually transmitted organisms, Neisseria gonorrhoeae and Chlamydia trachomatis, are present in many cases, and microorganisms comprising the endogenous vaginal and cervical flora are frequently associated with PID. This includes anaerobic and facultative bacteria, similar to those associated with bacterial vaginosis. Genital tract mycoplasmas, most importantly Mycoplasma genitalium, have recently also been implicated as a cause of acute PID. As a consequence, treatment regimens for acute PID should provide broad spectrum coverage that is effective against these microorganisms.

    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.

    Full Text Available Nowadays phytotherapy is increasingly being implemented into medical practice, especially for the prevention and treatment of many diseases. Acute respiratory viral infections are most common in childhood and in adults. Acute rhinitis, pharyngitis, tonsillitis, sinusitis, nasopharyngitis and acute laryngitis refer to diseases of the upper respiratory tract. The main reason for respiratory diseases in recurrent respiratory infection child is disorders of mucociliary and immune protection. The therapeutic value of medicinal plants is determined by their biologically active substances. The method of application of phytotherpy is an integral part of traditional medicine. Herbal medicine can be used at home and does not require special equipment. The main indications for the herbal medicine use in pediatrics are the initial stage of the disease as a primary method of treatment due to mild and low toxicity; as a supporting treatment for enhancing the protective forces of the child’s body during the disease deterioration. During the recovery period herbal medicine again occupies a leading position, especially in case of chronic diseases because it can be used for a long time and is well combined with synthetic drugs. The terms of appointment of herbs for children: prescription of medicinal plants for children must be individual according to indications, taking into account the child’s age; it is recommended to take into account the form and nature of the course of the main disease and comorbidities as well; at the initial stage of the treatment it is better to use some medicinal plants or species consisting of 2–3 plants and in the future a more complex composition; therapy with medicinal plants requires a long period to be used use, especially in chronic diseases; in the treatment of chronic diseases a good effect preventive courses of herbal medicine was revealed, which are appointed during seasonal exacerbations; in case of intolerance

    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.

    To determine the computed tomographic (CT) findings of acute pelvic inflammatory disease (PID). This retrospective, single-institution case-control study was approved by our institutional review board, and the informed consent was waived owing to the retrospective nature of the study. CT images of 32 women with clinically proven acute PID and 32 control subjects with other conditions of similar presentation were retrospectively reviewed. Analysis of CT findings included hepatic capsular enhancement, pelvic fat haziness, complicated ascites, uterine serosal enhancement, tubal thickening, endometritis, and oophoritis. Comparison of CT findings was performed with the Chi square test or the Fisher exact test and logistic regression analysis was used to determine significant CT findings in predicting PID. The CT findings that showed a statistically significant difference were hepatic capsular enhancement on late arterial phase (p = 0.003), pelvic fat haziness (p = 0.045), and tubal thickening (p = 0.001). Subsequent multivariate logistic regression analysis revealed that the presence of hepatic capsular enhancement on late arterial phase and tubal thickening were significant predictors of PID (hepatic capsular enhancement on late arterial phase, p = 0.015, odds ratio [OR] = 4.8; tubal thickening, p = 0.005, OR = 10.5). Diagnostic morphological CT findings in women with clinically proven PID and acute abdominal pain include hepatic capsular enhancement on late arterial phase and tubal thickening.

    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.

  7. Acute renal dysfunction in liver diseases

    Institute of Scientific and Technical Information of China (English)

    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.

    2016-04-01

    The acute respiratory distress syndrome (ARDS) is currently one of the most important critical entities given its high incidence, rate of mortality, long-term sequelae and non-specific pharmacological treatment. The histological hallmark of ARDS is diffuse alveolar damage (DAD). Approximately 50% of ARDS patients present DAD, the rest is made up of a heterogeneous group of histological patterns, many of which correspond to a well-recognized disease. For that reason, if these patterns could be diagnosed, patients could benefit from a treatment. Recently, the effect of DAD in clinical and analytical evolution of ARDS has been demonstrated, so the classical approach to ARDS as an entity defined solely by clinical, radiological and gasometrical variables should be reconsidered. This narrative review aims to examine the need to evolve from the concept of ARDS as a syndrome to ARDS as a specific disease. So we have raised 4 critical questions: a) What is a disease?; b) what is DAD?; c) how is DAD considered according to ARDS definition?, and d) what is the relationship between ARDS and DAD?

    2016-11-01

    Sickle cell disease is a chronic hematologic disease with a variety of acute, and often recurring, complications. Vaso-occlusive crisis, a unique but common presentation in sickle cell disease, can be challenging to manage. Acute chest syndrome is the leading cause of death in patients with sickle cell disease, occurring in more than half of patients who are hospitalized with a vaso-occlusive crisis. Uncommon diagnoses in children, such as stroke, priapism, and transient red cell aplasia, occur more frequently in patients with sickle cell disease and necessitate a degree of familiarity with the disease process and its management. Patients with sickle cell trait generally have a benign course, but are also subject to serious complications. This issue provides a current review of evidence-based management of the most common acute complications of sickle cell disease seen in pediatric patients in the emergency department.

    Full Text Available Chronic obstructive pulmonary disease (COPD is a chronic, progressive lung disease resulting from exposure to cigarette smoke, noxious gases, particulate matter, and air pollutants. COPD is exacerbated by acute inflammatory insults such as lung infections (viral and bacterial and air pollutants which further accelerate the steady decline in lung function. The chronic inflammatory process in the lung contributes to the extrapulmonary manifestations of COPD which are predominantly cardiovascular in nature. Here we review the significant burden of cardiovascular disease in COPD and discuss the clinical and pathological links between acute exacerbations of COPD and cardiovascular disease.

    After transplantation of nonrenal solid organs, an acute decline in kidney function develops in the majority of patients. In addition, a significant number of nonrenal solid organ transplant recipients develop chronic kidney disease, and some develop end-stage renal disease, requiring renal replacement therapy. The incidence varies depending on the transplanted organ. Acute kidney injury after nonrenal solid organ transplantation is associated with prolonged length of stay, cost, increased risk of death, de novo chronic kidney disease, and end-stage renal disease. This overview focuses on the risk factors for posttransplant acute kidney injury after liver and heart transplantation, integrating discussion of proteinuria and chronic kidney disease with emphasis on pathogenesis, histopathology, and management including the use of mechanistic target of rapamycin inhibition and costimulatory blockade.

    To evaluate the kinds of extratesticular diseases causing acute scrotal disorders by emergent sonography of the scrotum. Scrotal sonography in sixty-five patients, with age ranging from 5months to 82 years (mean : 27.3 years), with acute scrotal pain and swelling, was prospectively carried out by either a 10 or 7.5 MHz transducer. We evaluated the size and echogenicity of the epididymis, the presence of extratesticular solid mass or cyst, testicular involvement by extratesticular diseases, calcification, hydrocele and scrotal wall thickening. The most common cause of acute scrotal disorders was acute epididymitis (n= 50), followed by acute epididymo-orchitis (n = 4), mumps epididymo-orchitis (n = 2), enlarged epididymis secondary to testicular torsion (n = 2), infected hydrocele (n = 2), epididymal cyst (n = 2), rupture of varicocele (n = 1), angioneurotic edema (n = 1), and sperm granuloma (n = 1). Hydrocele was seen in 20 cases, and epididymal calcification was noted in 6 cases. Emergent scrotal sonography was useful for correct diagnosis and proper treatment in patients with acute scrotal disorders, especially in the differentiation of the acute epididymitis from other intrascrotal diseases

    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.

    AIM:To evaluate the relationship between peptic ulcer disease (PUD) and acute pancreatitis.METHODS:A cohort of 78 patients with acute pancreatitis were included in this study.The presence of PUD and the Helicobacter pylori (H.pylori ) status were assessed by an endoscopic method.The severity of acute pancreatitis was assessed using Ranson's score, the Acute Physiology and Chronic Health Evaluation (APACHE) Ⅱ score,computed tomography severity index and the clinical data during hospitalization,all of which were compared between the patients with and without PUD.The risk factors for PUD were also evaluated. RESULTS:Among 78 patients,41 patients (52.6%) with acute pancreatitis suffered from PUD,but only 13 (31.7%) patients with PUD were infected by H.pylori .On univariate analysis,male gender,an etiology of alcohol-induced pancreatitis,a history of smoking or alcohol consumption, elevated triglyceride and C-reactive protein levels, and high APACHE Ⅱ score were significantly associated with PUD.However,on multivariate logistic regression analysis,the APACHE Ⅱ score (odds ratio:7.69; 95% confidence interval:1.78-33.33; P < 0.01) was found to be the only independent risk factor for PUD.CONCLUSION:Patients with acute pancreatitis are liable to suffer from PUD.PUD is associated with severe acute pancreatitis according to the APACHE Ⅱ score, and treatment for PUD should be considered for patients with severe acute pancreatitis.

    Full Text Available Abstract Background Waterborne disease is a major risk for small water supplies in rural settings. This study was done to assess the impact of an educational intervention designed to improve water quality and estimate the contribution of water to the incidence of diarrhoeal disease in poor rural communities in Puerto Rico a two-part study was undertaken. Methods An educational intervention was delivered to communities relying on community water supplies. This intervention consisted of student operators and administrators supervising and assisting community members who voluntarily "operate" these systems. These voluntary operators had no previous training and were principally concerned with seeing that some water was delivered. The quality of that water was not something they either understood or addressed. The impact of this intervention was measured through water sampling for standard bacteriological indicators and a frank pathogen. In addition, face-to-face epidemiological studies designed to determine the base-line occurrence of diarrhoeal disease in the communities were conducted. Some 15 months after the intervention a further epidemiological study was conducted in both the intervention communities and in control communities that had not received any intervention. Results Diarrhoeal illness rates over a four week period prior to the intervention were 3.5%. Salmonella was isolated from all of 5 distributed samples prior to intervention and from only 2 of 12 samples after the intervention. In the 15 months follow-up study, illness rates were lower in the intervention compared to control communities (2.5% vs 3.6%% (RR = 0.70, 95%CI 0.43, 1.15, though this was not statistically significant. However, in the final Poisson regression model living in an intervention system (RR = 0.318; 95%CI 0.137 - 0.739 and owning a dog (RR = 0.597, 95%CI 0.145 - 0.962 was negatively associated with illness.

    2009-12-01

    Acute rheumatic fever and rheumatic heart disease are diseases of socioeconomic disadvantage. These diseases are common in developing countries and in Indigenous populations in industrialized countries. Clinicians who work with Indigenous populations need to maintain a high index of suspicion for the potential diagnosis of acute rheumatic fever, particularly in patients presenting with joint pain. Inexpensive medicines, such as aspirin, are the mainstay of symptomatic treatment of rheumatic fever; however, antiinflammatory treatment has no effect on the long-term rate of progression or severity of chronic valvular disease. The current focus of global efforts at prevention of rheumatic heart disease is on secondary prevention (regular administration of penicillin to prevent recurrent rheumatic fever), although primary prevention (timely treatment of streptococcal pharyngitis to prevent rheumatic fever) is also important in populations in which it is feasible.

    Full Text Available Abstract Introduction Legionnaires' disease is recognized as a multi-systemic illness. Afflicted patients may have pulmonary, renal, gastrointestinal tract and central nervous system complications. However, renal insufficiency is uncommon. The spectrum of renal involvement may range from a mild and transient elevation of serum creatinine levels to anuric renal failure requiring dialysis and may be linked to several causes. In our present case report, we would like to draw attention to the importance of the pathological documentation of acute renal failure by reporting a case of a patient with acute tubulointerstitial nephritis complicating Legionnaires' disease. Case presentation A 55-year-old Caucasian man was admitted to our hospital for community-acquired pneumonia complicated by acute renal failure. Legionella pneumophila serogroup type 1 was diagnosed. Although the patient's respiratory illness responded to intravenous erythromycin and ofloxacin therapy, his renal failure worsened, he became anuric, and hemodialysis was started. A renal biopsy was performed, which revealed severe tubulointerstitial nephritis. After initiation of steroid therapy, his renal function improved dramatically. Conclusions This case highlights the importance of kidney biopsies in cases where acute renal failure is a complicating factor in Legionnaires' disease. If the presence of acute tubulointerstitial nephritis can be confirmed, it will likely respond favorably to steroidal treatment and thus irreversible renal damage and chronic renal failure will be avoided.

    Chagas disease is caused by infection with the protozoan Trypanosoma cruzi, and although over 100 years have passed since the discovery of Chagas disease, it still presents an increasing problem for global public health. A plethora of information concerning the chronic phase of human Chagas disease, particularly the severe cardiac form, is available in the literature. However, information concerning events during the acute phase of the disease is scarce. In this review, we will discuss (1) the current status of acute Chagas disease cases globally, (2) the immunological findings related to the acute phase and their possible influence in disease outcome, and (3) reactivation of Chagas disease in immunocompromised individuals, a key point for transplantation and HIV infection management.

    The persistence of acute rheumatic fever continues to be seen globally. Once thought to be eradicated in various parts of the world, the disease came back with a vengeance secondary to a lack of diligence on the part of providers. Today, the global burden of group A streptococcal infection, the culprit of the numerous sequelae manifested in acute rheumatic fever, is considerable. Although a completely preventable disease, rheumatic fever continues to exist. It is a devastating disease that involves long-term, multisystem treatment and monitoring for patients who were unsuccessful at eradicating the precipitating group A streptococcal infection. Prevention is the key to resolving the dilemma of the disease's global burden, yet the method to yield its prevention still remains unknown. Thus, meticulous attention to implementing proper treatment is the mainstay and remains a top priority.

    The tick bite transmitted Lyme disease is one of the most common antropozoonosis, about 10 000 new infections are reported in Hungary each year. The progress and clinical presentation can vary, and carditis can occur in later stages. A serologically verified Lyme disease caused third degree atrioventricular block in young male presenting with presyncope. Based on the tick-bites mentioned a few weeks prior to hospital admission, Lyme carditis was considered with the administration of antibiotics and monitor observation. Typical skin lesions were not recognized and laboratory findings showed no pathology. An electrophysiological study recorded a predominant supra-His atrioventricular block. Total regression of conduction could be detected later and the serological tests established an underlying Lyme disease. Currently no definite treatment recommendation is available for the potentially reversible Lyme carditis. The tick bite seemed to be the key on our way to diagnosis; however, serological tests proved the disease to be older than one year. A detailed medical history and serological tests are essential in identifying the cause and pacemaker implantation can be avoided.

    A previously healthy 24-day-old boy presented with a 2-day history of fever and had a convulsion on the day of admission. MRI showed abnormal signal in the thalami, caudate nuclei and central white matter. Acute necrotising encephalopathy was diagnosed, other causes having been excluded after biochemical and haematological analysis of blood, urine and CSF. He recovered, but with spastic quadriparesis. At the age of 28 months, he suffered sudden deterioration of consciousness and motor weakness of his right limbs. MRI was consistent with an acute cerebrovascular accident. Angiography showed bilateral middle cerebral artery stenosis or frank occlusion with numerous lenticulostriate collateral vessels consistent with moyamoya disease. (orig.)

    During acute Lyme disease, bacteria can disseminate to the central nervous system (CNS), leading to the development of meningitis and other neurologic symptoms. Here we have analyzed pooled cerebrospinal fluid (CSF) allowing a deep view into the proteome for patients diagnosed with early disseminated Lyme disease and CSF inflammation. Additionally, we analyzed individual patient samples and quantified differences in protein abundance employing label-free quantitative mass spectrometry-based methods. We identified 108 proteins that differ significantly in abundance in patients with acute Lyme disease from controls. Comparison between infected patients and control subjects revealed differences in proteins in the CSF associated with cell death localized to brain synapses and others that likely originate from brain parenchyma.

    The growing epidemic of obesity and diabetes, the aging population as well as prevalence of drug abuse has led to significant increases in the rates of the closely associated acute and chronic kidney diseases, including diabetic nephropathy. Furthermore, evidence shows that parental behavior and diet can affect the phenotype of subsequent generations via epigenetic transmission mechanisms. These data suggest a strong influence of the environment on disease susceptibility and that, apart from genetic susceptibility, epigenetic mechanisms need to be evaluated to gain critical new information about kidney diseases. Epigenetics is the study of processes that control gene expression and phenotype without alterations in the underlying DNA sequence. Epigenetic modifications, including cytosine DNA methylation and covalent post-translational modifications of histones in chromatin, are part of the epigenome, the interface between the stable genome and the variable environment. This dynamic epigenetic layer responds to external environmental cues to influence the expression of genes associated with disease states. The field of epigenetics has seen remarkable growth in the past few years with significant advances in basic biology, contributions to human disease, as well as epigenomics technologies. Further understanding of how the renal cell epigenome is altered by metabolic and other stimuli can yield novel new insights into the pathogenesis of kidney diseases. In this review, we have discussed the current knowledge on the role of epigenetic mechanisms (primarily DNAme and histone modifications) in acute and chronic kidney diseases, and their translational potential to identify much needed new therapies.

Control population consisted of patients with chronic T. cruzi infection (30, acute toxoplasmosis 10, leishmaniasis (8, rheumatoid arthritis (3 and healthy individuals with negative serology for Chagas* disease (30. Acute chagasic patients were 100% CIC-IgG and 96.66% CIC-IgM positive whereas immunofluorescence tests yielded 90% and 86.66% of positivity for specific IgG and IgM antibodies, respectively. Chronic patients were 68% CIC-IgG and 0% CIC-IgM positive. The 30 negative and the 21 cross-reaction controls proved negative for ELISA (CIC-IgM and CIC-IgG. The high sensitivity of ELISA assays would allow early immunologic diagnosis, as well as prompt treatment, of acute T. cruzi infection, thus eliminating the problem of the false-positive and false-negative results which affects traditional methods for detection of circulating antibodies.

    Full Text Available Abstract Antithrombotic therapy is the cornerstone of the treatment of acute coronary syndromes, but there is now evidence which indicates that by blocking inflammation, thrombosis and thus, acute coronary events, could be lowered. The concept of athero-inflammation emerges as the meeting point of different morbidities; dyslipemia, diabetes, hypertension, obesity, immunity, infection, hyperhomocyteinemia, smoking, etc. usual named as risk factors. Thus, beside specific drugs, earliest treatment, in the stage of inflammation, using anti-inflammatory drugs, should be considered since in patients with increased risk of acute coronary process are likely to have many point of origen throughout the coronary arteries. There are a body of evidences for supporting the potential of anti-inflammatory therapy to the prevention of inflammation and atherosclerosis. COX-2 inhibition may decrease endothelial inflammation reducing monocytes infiltration improving vascular cells function, plaque stability and probably resulting in a decrease of coronary atherothrombotic events. Trials including large numbers of patients in prospective double-blind randomized studies worthwhile to confirm the efficacy of NSAID, mainly, COX-2 inhibitors, together with aspirin in the prevention of coronary events in patients with acute coronary disease.

    Acute dyspnea with pulmonary oedema in postpartum is uncommon but life-threatening event. Contributing factors for pulmonary oedema include, administration of tocolytics, underlying cardiac disease, iatrogenic fluid overload and preeclampsia acounting 0.08% of pregnancies. Pulmonary embolism, amniotic fluid embolism, pneumonia, aspiration and pulmonary oedema are some of the potentially devastating conditions that should be considered by the attending physician. Here, we report a case of postpartum acute pulmonary oedema referred to causality after an emergency caesarean section in a private hospital. No matter what the underlying pathology, prompt administration and appropriate resuscitation is always the first priority. Only after the patient has been stabilized attention must be turned to diagnosis and specific treatment. A diagnosis of severe Mitral Stenosis, probably of rheumatic origin was made after stabilizing the patient.

    Full Text Available Near complete infiltration of the liver secondary to metastasis from the head and neck cancer is a rare occurrence. The prognosis of liver failure associated with malignant infiltration is extremely poor; the survival time of patients is extremely low. We present a case of acute warfarin toxicity as initial manifestation of metastatic liver disease. Our patient is a 64-year-old woman presenting with epigastric pain and discomfort, found to have unrecordable International Normalized Ratio. She rapidly deteriorated with acute respiratory failure requiring mechanical ventilation, profound shock requiring high dose vasopressor infusion, severe coagulopathy, worsening liver enzymes with worsening of lactic acidosis and severe metabolic abnormalities, and refractory to aggressive supportive care and died in less than 48 hours. Autopsy revealed that >90% of the liver was replaced by tumor masses.

    The present paper is devoted to selection of an optimal treatment method for acute periodontitis by using fuzzy Choquet integral-based approach. We consider application of different treatment methods depending on development stages and symptoms of the disease. The effectiveness of application of different treatment methods in each stage of the disease is linguistically evaluated by a dentist. The stages of the disease are also linguistically described by a dentist. Dentist's linguistic evaluations are represented by fuzzy sets. The total effectiveness of the each considered treatment method is calculated by using fuzzy Choquet integral with fuzzy number-valued integrand and fuzzy number-valued fuzzy measure. The most effective treatment method is determined by using fuzzy ranking method.

    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.

    To evaluate the utility of Color doppler US in the patients with acute scrotal pain, we retrospectively analyzed 37 patients referred for Color Doppler US of the scrotum. The diagnosis was confirmed by means of appropriate response to antibiotic treatment (31 cases) or surgery (6 cases). Thirty one of 37 patients were diagnosed as inflammatory disease (24 cases of epididymitis, 7 cases of epididymo-orchitis). Twenty three of 24cases of epididymitis had increased epididymal flow, while 6 of 7 cases of epididymo-orchitis had increased epididymal and testicular flow. Five patients were confirmed as testicular torsion, and in all cases nointratesticular blood flow was identified on the symptomatic side. In one case of torsion of appendix testis, epididymis was enlarged and there were increased signals suggesting epididymitis on Color Doppler US, but was confirmed by surgery as torsion of appendix testis. Therefore, the differentiation between torsion and inflammatory disease was possible by using Color Doppler US of the scrotum in 34 of 37 cases in our study. On the basis of our results, we may conclude that Color Doppler US can simultaneously display blood flow and detailed anatomic images, and function as an effective means of evaluating patients with acute scrotal disease

    Kimura disease (KD) is an immune-mediated chronic inflammatory disease of unknown etiology. KD has many complications associated with hypereosinophilia, including various forms of allergic reactions and eosinophilic lung disease. Additionally, hypereosinophilia is associated with hypercoagulability, which may lead to thromboembolic events. A 36-year-old man with KD presented with acute limb ischemia and coronary artery occlusion. He underwent thrombectomy, partial endarterectomy of both popliteal arteries, and coronary artery stent insertion. KD is a systemic disease that affects many organs and presents with thromboembolism and vasculitis. In a patient with KD, physicians should evaluate the vascular system, including the coronary arteries. PMID:28382271

    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.

    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.

    To describe the cognitive, functional, and nutritional features of patients admitted to a Special Acute Care Unit (SACU) for elderly patients with Alzheimer's disease (AD). One-year observational study of patients with AD and other related disorders hospitalized in the SACU, Department of Geriatrics, Toulouse university Hospital during 2005. A comprehensive neurocognitive and non-cognitive geriatric assessment was performed. Data on full clinical evaluation, nutritional status, activities of daily living (ADL), gait and balance disturbance, behavioural and psychological symptoms (BPSD), and sociodemographics were recorded. Four-hundred and ninety-two patients were assessed. Their mean age was 81.1+/-7.7, the mean length of stay was 10.7+/-6.3 days, 62% were female, 63.9% were admitted from their own home and 30.4% from a nursing home. Eighty percent of patients had probable Alzheimer's disease or mixed dementia, less than 20% had other causes of dementia. Results of their comprehensive assessment showed a mean mini-mental state examination of 14.5+/-7.4; a mean total ADL score of 3.7+/-1.7. Seventy-seven percent had gait or balance disturbances; 90% of patients presented an unsatisfactory nutritional status. The most common reason for admission was BPSD. AD complications are responsible for many acute admissions. Elderly patients suffering from dementia represent a population with unique clinical characteristics. Further randomised clinical trials are needed to evaluate the effectiveness of Special Acute Care Units for patients with AD and other related disorders. Copyright (c) 2007 John Wiley & Sons, Ltd.

    Full Text Available Acute erythroid leukemia (AEL is a rare subtype of acute myeloid leukemia(AML, characterized by predominant erythroid proliferation. The 2008 WorldHealth Organization (WHO classification of AML defined two AEL subtypes:erythroleukaemia (EL, in which erythroid precursors account for 50% or moreof all nucleated bone marrow cells and myeloblasts account for 20% or more ofthe nonerythroid cell population; and pure erythroid leukemia (PEL, in whicherythroid precursors account for 80% or more of all nucleated bone marrowcells. We report the case of an elderly female patient with wasting syndromeand pancytopenia without evidence of blasts in peripheral blood. A diagnosisof PEL was established on the basis of bone marrow biopsy findings. Thepatient died on postadmission day 20, and an autopsy was performed. Wereclassified the disease as EL on the basis of the autopsy findings, whichincluded myeloblasts accounting for more than 20% of the nonerythroid cellsin the bone marrow, as well as leukemic infiltration and myeloid metaplasia insolid organs, such as the liver, spleen, kidneys, adrenal glands, and abdominallymph nodes. A rare disease, AEL accounts for less than 5% of all AMLs and ispractically a diagnosis of exclusion. Autopsy reports of AEL are extremely rarein the literature. We demonstrate that in the case reported here, leukemia cellstended to infiltrate solid organs with myeloid metaplasia. Our findings alsoshow that a larger neoplastic bone marrow sample is crucial to the correctdiagnosis of EL, which is based on morphological and quantitative criteria.

    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.

    Liver abnormalities in the course of Adult Onset Still's Disease (AOSD), both in form of hepatomegaly and elevation of hepatic enzymes, have been reported in up to three-quarts of the affected patients. These abnormalities may reflect disease activity or may be induced by drugs. Only in a few of this patients a liver biopsy was performed. However liver histology has shown, generally, non specific abnormalities or even normal pictures. We have recently observed a 47-year-old woman with a febrile illness started five months before, who after pertinent investigation was diagnosed as AOSD (according to criteria of Yamaguchi et al.). Apart from laboratory findings characteristic of an inflammatory disease, in absence of drug therapies the biochemical data showed raised levels of aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase and aminoglutamil transferase. Serological tests for either viral hepatitis viruses (HAV, HBV, HCV) or other viruses were negative. Ultrasonographic examination of gallbladder and bile ducts did not find gallstones or other abnormalities. A liver biopsy was performed, which histopathologic examination showed moderate fatty methamorphosis with focal areas of hepatocellular swelling with minimal necrosis, mild Kuppfer cell hyperplasia, portal and sinusoidal infiltrates of mononuclear cells. This picture consisted with the diagnosis of an acute unspecific reactive hepatitis.

    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.

    Full Text Available Introduction: Acute acalculous cholecystitis (AAC occurs more frequently in critically ill patients, in the immediate postoperative period, after trauma or extensive burns. It has a high rate of morbidity and mortality. Ischemia, infection and vesicular stasis are determinants in its pathogenesis. Material and method: Retrospective study including all cases of AAC diagnosed in our pediatric intensive care unit between January 1997 and December 2012. Results: We included 7 patients, all associated with viral or bacterial infection. All of them suffered from abdominal pain, mainly localized in the right upper quadrant, jaundice and dark urine. Abdominal ultrasound showed thickening and hypervascularity of the gallbladder wall in all cases. The outcome was satisfactory without surgery in all patients. Conclusions: The clinical presentation is oligosymptomatic within severe systemic diseases. The AAC should be suspected in the appearance of any abdominal pain with jaundice/dark urine and hypertransaminasemia in patients suffering from critical or serious infections.

    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.

  15. Hyponatremia in acute brain disease: the cerebral salt wasting syndrome.

    Betjes, Michiel G.H.

    2002-02-01

    Hyponatremia in acute brain disease is a common occurrence, especially after an aneurysmal subarachnoid hemorrhage. Originally, excessive natriuresis, called cerebral salt wasting, and later the syndrome of inappropriate antidiuretic hormone secretion (SIADH), were considered to be the causes of hyponatremia. In recent years, it has become clear that most of these patients are volume-depleted and have a negative sodium balance, consistent with the original description of cerebral salt wasting. Elevated plasma concentrations of atrial or brain natriuretic peptide have been identified as the putative natriuretic factor. Hyponatremia and volume depletion may aggravate neurological symptoms, and timely treatment with adequate replacement of water and NaCl is essential. The use of fludrocortisone to increase sodium reabsorption by the renal tubules may be an alternative approach.

    Some infectious organisms may give rise to acute pancreatitis; brucellosis, however, extremely rarely leads to acute pancreatitis. A 40-year-old man was diagnosed with acute pancreatitis, the etiology of which was determined to be acute brucellosis. The patient was discharged without complications approximately 15 days after the initiation of trimethoprim-sulfamethoxazole and doxycycline treatment. Brucella infections may rarely be complicated by acute pancreatitis. Thus, brucellosis should be remembered in the etiology of acute pancreatitis in regions such as Turkey, where Brucella infections are endemic.

    The course of sickle cell disease (SCD) may be complicated by neurologic events, mainly bactérial meningitidis and stroke. We retrospectively studied all cases with acute encephalic manifestations (AEM) in a cohort of 461 children and adolescents with SCD followed at Albert Royer Children Hospital of Dakar (Senegal) from january 1991 to december 2000 (ten years). Among them 438 had sickle cell anemia (SCA), 19 SC disease and 4 S-beta thalassemia (3 S-beta+, 1 S-beta0). Seven patients, all with SCA, presented antecedents of AEM revealed by flacid and proportionnal hemiplegia evoking stroke. Prevalence of these AEM was 1.5 per cent among patients with SCD and 1.6 per cent among those with SCA. They were 4 girls and 3 boys (sex ratio = 0.75) aged 4 to 8.5 years when occurred the first accident. We observed no clinical or biological distinctive characteristic of SCA in these patients compared to those without crebrovascular accident. Recurrence was observed once in a boy after a 12 months interval and twice in a girl after 20 and 60 months intervals successively. No transfusionnal program was applied to prevent recurrent stroke because of insufficient conditions for long-term transfusion. Stroke appears to be rare in senegalese children with SCD. However it poses in our context the major problem of applicability of transfusionnal program which constitute the only therapy universally recognised to be effective to prevent recurrence. Nevertheless hydroxyurea could be a satisfactory alternative.

    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.

    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.

    Objective: Acute exacerbations of chronic obstructive pulmonary disease (AECOPD) cause significant morbidity, mortality, and an inexorable decline of lung function. Data from developed countries have shown viruses to be important causes of AECOPD, but data from developing countries like India are scant. We set out to determine the contribution of viruses in the causation of hospitalized patients with AECOPD. Methods: Twin nasopharyngeal/oropharyngeal swabs collected from 233 patients admitted with an acute AECOPD and tested for respiratory viruses including respiratory syncytial virus A and B, parainfluenza were (PIV) 1, 2, 3, and 4, human metapneumovirus (hMPV) A and B, influenza A and B, enterovirus, corona NL65, OC43, and 229E viruses, adenovirus 2 and 4, rhinovirus, and bocavirus, by duplex real time reverse-transcription polymerase chain reaction (qRT-PCR) using CDC approved primers and probes. Samples positive for influenza A were subtyped for A/H1N1pdm09 and A/H3N2 whereas influenza B samples were subtyped into B/Yamagata and B/Victoria subtypes, using primers and probes recommended by CDC, USA. Results: Respiratory viruses were detected in 46 (19.7%) cases, influenza A/H3N2 and rhinoviruses being the most common viruses detected. More than one virus was isolated in four cases consisting of hMPV-B + adeno-2 + Inf-B; rhino + H3N2, PIV-1 + rhino; and PIV-1+ hMPV-B in one case each. Ancillary supportive therapeutic measures included bronchodilators, antibiotics, steroids, and ventilation (noninvasive in 42 and invasive in 4). Antiviral therapy was instituted in influenza-positive patients. Three patients with A/H3N2 infection died during hospitalization. Conclusions: We conclude that respiratory viruses are important contributors to AECOPD in India. Our data calls for prompt investigation during an exacerbation for viruses to obviate inappropriate antibiotic use and institute antiviral therapy in viral disease amenable to antiviral therapy.

    Periodontal disease has been linked to adverse cardiovascular events by unknown mechanisms. C-reactive protein is a systemic marker released during the acute phase of an inflammatory response and is a prognostic marker for cardiovascular disease, with elevated serum levels being reported during periodontal disease. Studies also reported elevated levels of various other acute-phase reactants in periodontal disease. It has been reported extensively in the literature that treatment of periodontal infections can significantly lower serum levels of C-reactive protein. Therefore, an understanding of the relationship between acute-phase response and the progression of periodontal disease and other systemic health complications would have a profound effect on the periodontal treatment strategies. In view of this fact, the present review highlights an overview of acute-phase reactants and their role in periodontal disease. © 2014 Wiley Publishing Asia Pty Ltd.

    Full Text Available Adult coeliac disease commonly presents without classical symptoms as chronic diarrhea and weight loss. We describe the case of a 31-year-old woman with persistent life-threatening hypokalemia, acute renal failure, and acute quadriplegia due to diarrhea that had continued for one month. Although there are cases of coeliac disease diagnosed with hypokalemic rhabdomyolysis in the literature, none of the cases developed acute renal failure. This is the first case in the literature diagnosed with acute renal failure due to hypokalemic rhabdomyolysis as a presentation of coeliac disease. In acute renal failure cases that present with hypokalemic rhabdomyolysis due to severe diarrhea, coeliac disease should be considered as a differential diagnosis despite the negative antigliadin IgA antibody.

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.

    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.

    Acute rheumatic fever is a nonsuppurative, immune-mediated consequence of group A streptococcal pharyngitis (strep throat). Recurrent or severe acute rheumatic fever can cause permanent cardiac valve damage and rheumatic heart disease, which increases the risk for cardiac conditions (e.g., infective endocarditis, stroke, and congestive heart failure). Antibiotics can prevent acute rheumatic fever if administered no more than 9 days after symptom onset. Long-term benzathine penicillin G (BPG) injections are effective in preventing recurrent acute rheumatic fever attacks and are recommended to be administered every 3-4 weeks for 10 years or until age 21 years to children who receive a diagnosis of acute rheumatic fever. During August 2013, in response to anecdotal reports of increasing rates of acute rheumatic fever and rheumatic heart disease, CDC collaborated with the American Samoa Department of Health and the Lyndon B. Johnson Tropical Medical Center (the only hospital in American Samoa) to quantify the number of cases of pediatric acute rheumatic fever and rheumatic heart disease in American Samoa and to assess the potential roles of missed pharyngitis diagnosis, lack of timely prophylaxis prescription, and compliance with prescribed BPG prophylaxis. Using data from medical records, acute rheumatic fever incidence was calculated as 1.1 and 1.5 cases per 1,000 children aged ≤18 years in 2011 and 2012, respectively; 49% of those with acute rheumatic fever subsequently received a diagnosis of rheumatic heart disease. Noncompliance with recommended prophylaxis with BPG after physician-diagnosed acute rheumatic fever was noted for 22 (34%) of 65 patients. Rheumatic heart disease point prevalence was 3.2 cases per 1,000 children in August 2013. Establishment of a coordinated acute rheumatic fever and rheumatic heart disease control program in American Samoa, likely would improve diagnosis, treatment, and patient compliance with BPG prophylaxis.

    This study has been undertaken to investigate the isolation and identification of EPEC strains from paediatric diarrhoeal patients. The study was carried out in the department of Microbiology, Sir Salimullah Medical College & Mitford Hospital, Bangladesh during January to December, 2011. Total 272 samples were studied. Samples from patients with diarrhoea were collected from two tertiary care hospital. At first Esch. coli were isolated from these specimens using standard microbiological techniques and then EPEC strains were identified on the basis of presence of bundle forming pilus (bfpA) gene. Virulence of EPEC strains were determined by detection of bfpA gene and observing localized adherence (LA) in HeLa cell adherence assay. Esch. coli was isolated and identified from all the 272 samples from patients using standard microbiological techniques. Among 272 samples 20(7.35%) isolates were identified as EPEC on the basis of presence of bfpA gene detected by polymerase chain reaction. EPEC strains were identified from those 240 samples, from which Esch. coli had been isolated only. Out of twenty EPEC strains, 17 strains (85%) showed a pattern of localized adherence in Hela cell adherence assay. EPEC strains can be identified by bfpA gene detection and by adherence assays. HeLa cell adherence assay is the most specific method for detection of EPEC strains which has bfpA gene, responsible for localized adherence (LA) in HeLa cell line. Rapid and reliable detection of EPEC is required for successful microbiological surveillance and for treatment of EPEC mediated diarrhoeal disease.

    Kawasaki disease is a systemic vasculitis predominately affecting coronary arteries. Hemophagocytic lymphohistiocytosis can complicate the course of Kawasaki disease. Rare cases of secondary hemophagocytic lymphohistiocytosis occurring during the acute phase of Kawasaki disease have been reported. We report here a 4 month-old girl with diffuse coronary ectasia and secondary hemophagocytic lymphohistiocytosis occurring during the acute phase of incomplete Kawasaki disease. Due to the large overlap in clinical symptoms, the presence of atypical findings for Kawasaki disease should suggest the possible diagnosis of hemophagocytic lymphohistiocytosis in these patients.

    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.)

    There is considerable interest in developing techniques to detect and/or quantify remaining leukaemia cells termed measurable or, less precisely, minimal residual disease (MRD) in persons with acute myeloid leukaemia (AML) in complete remission defined by cytomorphological criteria. An important reason for AML MRD-testing is the possibility of estimating the likelihood (and timing) of leukaemia relapse. A perfect MRD-test would precisely quantify leukaemia cells biologically able and likely to cause leukaemia relapse within a defined interval. AML is genetically diverse and there is currently no uniform approach to detecting such cells. Several technologies focused on immune phenotype or cytogenetic and/or molecular abnormalities have been developed, each with advantages and disadvantages. Many studies report a positive MRD-test at diverse time points during AML therapy identifies persons with a higher risk of leukaemia relapse compared with those with a negative MRD-test even after adjusting for other prognostic and predictive variables. No MRD-test in AML has perfect sensitivity and specificity for relapse prediction at the cohort- or subject levels and there are substantial rates of false-positive and -negative tests. Despite these limitations, correlations between MRD-test results and relapse risk have generated interest in MRD-test result-directed therapy interventions. However, convincing proof that a specific intervention will reduce relapse risk in persons with a positive MRD-test is lacking and needs testing in randomized trials. Routine clinical use of MRD-testing requires further refinements and standardization/harmonization of assay platforms and results reporting. Such data are needed to determine whether results of MRD-testing can be used as a surrogate end point in AML therapy trials. This could make drug-testing more efficient and accelerate regulatory approvals. Although MRD-testing in AML has advanced substantially, much remains to be done.

    The present study was conducted to investigate the prevalence and diversity of Arcobacter and Campylobacter spp. in 298 stool samples of patients with diarrhoea, collected from 22 Portuguese hospitals, between September and November 2012. Detection of Arcobacter and Campylobacter spp. was performed using molecular-based detection techniques, such as real-time fluorescence resonance energy transfer PCR, species-specific PCR, and sequencing of amplified PCR products. Overall, 1.3% of the samples were positive for Arcobacter butzleri and 0.3% for Arcobacter cryaerophilus. Campylobacter spp. were found in 31.9% of diarrhoeic faeces. Campylobacter jejuni and Campylobacter concisus were the most prevalent species (13.7% and 8.0%, respectively). The prevalence of Arcobacter and Campylobacter spp. was significantly different between children and adults (39.7% versus 22.8%, P = 0.003). We underline the high prevalence of these pathogens in diarrhoeal samples among Portuguese patients, with particular relevance in the paediatric age group.

  1. 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.

    Phenotypic and genetic characteristics of Shigella spp. isolated from diarrhoeal and asymptomatic children aged up to 5 years were analysed in this study. In total, 91 and 17 isolates were identified from diarrhoeal (case) and asymptomatic (control) children, respectively. All the isolates were tested for antimicrobial resistance, the presence of integrons, plasmid-mediated quinolone resistance (PMQR), virulence-associated genes and Shigella pathogenicity island (SH-PAI). The majority of the Shigella spp. from cases (68.1%) and controls (82.3%) were found to be resistant to fluoroquinolones. Integron carriage was detected more in cases (76.9%) than in controls (35.5%). Atypical class 1 integron was detected exclusively in Shigella flexneri from cases but not from the controls. PMQR genes such as aac(6')-Ib-cr and qnrS1 were detected in 82.4 and 14.3% of the isolates from cases and in 53 and 17.6% in controls, respectively. Shigella isolates from cases as well as from controls were positive for the invasive plasmid antigen H-encoding gene ipaH. The other virulence genes such as virF, sat, setA, setB, sen and ial were detected in Shigella isolates in 80.2, 49.4, 27.4, 27.4, 80.2 and 79.1% of cases and in 64.7, 52.9, 17.6, 17.6, 64.7 and 64.7% of controls, respectively. The entire SH-PAI was detected in S. flexneri serotype 2a from cases and controls. In an isolate from a control child, the SH-PAI was truncated. Integrons, PMQR and virulence-encoding genes were detected more frequently in cases than in controls. In diarrhoea endemic areas, asymptomatic carriers may play a crucial role in the transmission of multidrug-resistant Shigella spp. with all the putative virulence genes.

    Chronic obstructive pulmonary disease (COPD) and heart failure (HF) are chronic diseases that impart significant health and care costs to the patient and health system. Limited access to health services affects disease severity and functional status. Telemonitoring has shown promise in reducing acute care utilization for chronic disease patients, but the benefit for the underserved has not been determined. We evaluated acute care utilization outcomes following an acute event of a 90-day transitional care program integrating telemonitoring technology and home visits for underserved COPD and HF patients. Patients were enrolled into the program between October 2010 and August 2012. Primary outcomes included rates of emergency department (ED) visits and all-cause re-admission at 30, 90, and 180 days postdischarge. Program and functional status at enrollment and discharge and satisfaction with telemonitoring at discharge were measured. Telemonitoring included daily symptomatology recording and was removed at 90 days. A control cohort was identified through electronic health records and propensity-matched via 15 variables to achieve a sample size with balanced baseline characteristics. Program patients showed 50% reduction in 30-day re-admission and 13-19% reduction in 180-day re-admission compared with control patients. There was no significant difference in ED utilization. Patients were satisfied with telemonitoring services, and functional status improved by program end. This feasibility study suggests telemonitoring in the context of a transitional care model following an acute event may reduce all-cause 30-day re-admissions by up to 50% and has the potential to reduce long-term acute care utilization and thus care costs. More rigorous and long-term investigation is warranted.

    The societal and individual burden caused by acute and chronic lower extremity venous disease is considerable. In the past several decades, minimally invasive endovascular interventions have been developed to reduce thrombus burden in the setting of acute deep venous thrombosis to prevent both short- and long-term morbidity and to recanalize chronically occluded or stenosed postthrombotic or nonthrombotic veins in symptomatic patients. This state-of-the-art review provides an overview of the techniques and challenges, rationale, patient selection criteria, complications, postinterventional care, and outcomes data for endovascular intervention in the setting of acute and chronic lower extremity deep venous disease. Online supplemental material is available for this article.

    Possible relationships between Moschcowitz's disease and acute systemic lupus erythematosus are analyzed based on findings in one case. Initial exclusively buccal symptoms suggested a diagnosis of lupus, and then of Moschcowitz's disease leading to a fatal outcome. The main points discussed relate to diagnostic difficulties to enable distinction between the two diseases. A thrombotic thrombopenic purpura during the second phase of the disease showed a characteristic microangiopathy associated with a non-autoimmune hemolytic anemia and a schizocytosis: two forms of the affection are recognized, one with a chronic and one with an acute course. The latter, which has a fulminating progression leading to death, was that described in the case reported.

    To determine the frequency of acute care visits and risk factors for central nervous system (CNS) events in children with homozygous sickle cell disease (SCD-SS) with an acute headache. This is a retrospective cohort study of acute care visits for headache in children with SCD-SS. The prevalence of headache visits, neuroimaging evaluation, and acute CNS events were calculated and clinical and laboratory variables assessed. Headache was the chief complaint in 102 of 2685 acute care visits (3.8%) by children with SCD-SS. Acute CNS events were detected in 6.9% of these visits. Neuroimaging was performed in 42.2% of visits, and acute CNS events were identified in 16.3% of studies. Factors associated with acute CNS events included older age, history of stroke, transient ischemic attack, or seizure, neurologic symptoms, focal neurologic exam findings, and elevated platelets. Acute headache is common in pediatric SCD-SS and more frequently associated with acute CNS events than in the general pediatric population. A history of stroke, transient ischemic attack, seizures, neurologic symptoms, focal neurologic exam, or elevated platelet counts at presentation warrant confirmatory imaging studies. Whether a more limited workup is adequate for other children should be confirmed in a larger, prospective study. Copyright © 2011 Mosby, Inc. All rights reserved.

    To construct a decision tree based on CT findings to differentiate acute pelvic inflammatory disease (PID) from acute appendicitis (AA) in women with lower abdominal pain and inflammatory syndrome. This retrospective study was approved by our institutional review board and informed consent was waived. Contrast-enhanced CT studies of 109 women with acute PID and 218 age-matched women with AA were retrospectively and independently reviewed by two radiologists to identify CT findings predictive of PID or AA. Surgical and laboratory data were used for the PID and AA reference standard. Appropriate tests were performed to compare PID and AA and a CT decision tree using the classification and regression tree (CART) algorithm was generated. The median patient age was 28 years (interquartile range, 22-39 years). According to the decision tree, an appendiceal diameter ≥ 7 mm was the most discriminating criterion for differentiating acute PID and AA, followed by a left tubal diameter ≥ 10 mm, with a global accuracy of 98.2 % (95 % CI: 96-99.4). Appendiceal diameter and left tubal thickening are the most discriminating CT criteria for differentiating acute PID from AA. • Appendiceal diameter and marked left tubal thickening allow differentiating PID from AA. • PID should be considered if appendiceal diameter is < 7 mm. • Marked left tubal diameter indicates PID rather than AA when enlarged appendix. • No pathological CT findings were identified in 5 % of PID patients.

    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

    To analyze the association between the admission systolic blood pressure (SBP) and 30-day outcome in patients with acute cerebrovascular disease. The REgistro NAcional Mexicano de Enfermedad VAScular Cerebral (RENAMEVASC) is a hospital-based multicenter registry performed between November 2002 and October 2004. A total of 2000 patients with clinical syndromes of acute cerebrovascular disease confirmed by neuroimaging were registered. The modified Rankin scale was used for outcome stratification. We analyzed 1721 patients who had registered their SBP: 78 (4.5%) had transient ischemic attack, 894 (51.9%) brain infarction, 534 (30.9%) intracerebral hemorrhage, 165 (9.6%) subarachnoid hemorrhage and 50 (2.9%) cerebral venous thrombosis. Among 1036 (60.2%) patients with the antecedent of hypertension, only 32.4% had regular treatment. The 30-day case fatality rate presented a J pattern with respect to SBP, so that the risk of death was highest in 65 years (RR: 2.16, IC 95%: 1.74 - 2.67). Both hypotension and significant arterial hypertension at hospital admission are associated with an adverse outcome after acute cerebrovascular disease. Nevertheless, a good functional outcome can be attained in a wide range of SBP.

    Chagas disease (CD) is a tropical parasitic disease largely underdiagnosed and mostly asymptomatic affecting marginalized rural populations. Argentina regularly reports acute cases of CD, mostly young individuals under 14 years old. There is a void of knowledge of health care seeking behavior in subjects experiencing a CD acute condition. Early treatment of the acute case is crucial to limit subsequent development of disease. The article explores how the health outcome of persons with acute CD may be conditioned by their health care seeking behavior. The study, with a qualitative approach, was carried out in rural areas of Santiago del Estero Province, a high risk endemic region for vector transmission of CD. Narratives of 25 in-depth interviews carried out in 2005 and 2006 are analyzed identifying patterns of health care seeking behavior followed by acute cases. Through the retrospective recall of paths for diagnoses, weaknesses of disease information, knowledge at the household level, and underperformance at the provincial health care system level are detected. The misdiagnoses were a major factor in delaying a health care response. The study results expose lost opportunities for the health care system to effectively record CD acute cases. PMID:27829843

    Acute asthma and chronic obstructive pulmonary disease (COPD) exacerbations are the most common respiratory diseases requiring emergent medical evaluation and treatment. Asthma and COPD are chronic, debilitating disease processes that have been differentiated traditionally by the presence or absence of reversible airflow obstruction. Asthma and COPD exacerbations impose an enormous economic burden on the US health care budget. In daily clinical practice, it is difficult to differentiate these 2 obstructive processes based on their symptoms, and on their nearly identical acute treatment strategies; major differences are important when discussing anatomic sites involved, long-term prognosis, and the nature of inflammatory markers.

    Home-based salt-sugar solution (SSS) prepared with labon (locally produced sea salt) and gur (unrefined brown sugar) has been recommended as a cheap, locally available and a simple tool to prevent and treat diarrhoeal dehydration. Preparation of labon-gur SSS is demonstrated to the patients...... and the attendants at ICDDR, Bangladesh. To evaluate performances, 150 mothers were asked to measure labon and gur by finger pinch and first method and 100 mothers measured half a seer of water to prepare labon-gur SSS, shortly after the demonstration sessions. 4.0% of the samples exceeded the upper safety limit...... this knowledge. Our study suggests that demonstration of home-based SSS in a diarrhoeal hospital may positively affect health education and that health personnel should actively participate in increasing health awareness....

    2016-03-01

    Full Text Available 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.

    2015-08-01

    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.

  1. Acute calcific tendonitis of dorsal interosseous muscles of the hand: uncommon site of a frequent disease

    Full Text Available Acute calcific tendinopathy is one of the manifestations of hydroxyapatite crystal deposition disease. While it is more frequent in the shoulder, it has been described in virtually all areas of the body, but rarely in the muscles of the hand. Its etiopathogenesis is not yet fully understood and despite being a fairly frequent condition, it is commonly misdiagnosed. The onset of the disease is usually acute and resolves spontaneously. Acute calcific tendinitis of the interosseous tendons of the hand is an uncommon site of a frequent condition. The clinical presentation is similar to other entities, thus errors in diagnosis frequently occur, resulting in over-treatment or unnecessary tests. We describe a case of acute calcific tendinitis of the interosseous muscles of the hand with a brief review of the current literature with emphasis on diagnostic imaging methods.

    Mankind is at risk for accidental exposure to ionizing radiation. The experience in evaluating and treating victims of radiation exposure is briefly reviewed based upon accidents occurring over the past 25 years. Individual cases of acute toxicities to the skin, gastrointestinal tract, liver and bone marrow are presented. Biodosimetry (utilizing chromosome analysis of peripheral blood lymphocytes and bone marrow and electron spin resonance spectrometry of dental enamel) has been utilized in radiation accidents to assess individual dose. Variability in the dose of ionizing radiation received is typical among the population affected by the Chernobyl accident. Whereas the acute radiation syndrome resulting in a high mortality has been well-documented, little information is available regarding the effects of chronic, low-level exposure from the Chernobyl accident.

    To determine the magnitude of morbidity related to diarrhea among children under 5 years of age, a study was carried out in 4 slum areas of Delhi in May-June 1984. Of the 3645 children surveyed, 963 (26.4%) had suffered from 1 or more new episodes of diarrhea in the 2 weeks preceding the survey. This suggests a mean annual incidence of diarrhea in the slums of Delhi of 7.9 episodes/child, with an average duration of 3.9 days/episode. The mean episodes/child/year ranged from a low of 4.1 in Ballimaran to a high of 11.9 in the Seelampur slum. The incidence of diarrhea was highest in chldren 7-12 months of age (13.6 episodes/year). In 24.2% of the diarrhea episodes, the families sought no medical help. 54.5% of cases were treated by private practitioners, 21% were seen at hospitals, and 0.3% were treated with home remedies. Only 20.2% of mothers of children with diarrhea were familiar with oral rehydration therapy, despite the easy accessibility of information about this treatment in the slum areas. Among the mothers with knowledge of oral rehydration, 47.9% used it for all diarrhea episodes, 33.0% used it for selected episodes, and 19.1% had never used it. A higher incidence of diarrhea was found among children living in homes where unfiltered water from handpumps was used for drinking or where residents defecated in open fields. Children with grade 2 or 3 malnutrition also showed a higher incidence of diarrhea. Among the socioeconomic parameters, diarrhea was positively associated with low female income and illiteracy on the part of the mother. Finally, infants who were exclusively breastfed had a lower incidence of diarrhea than those who were receiving supplementary feedings.

    2004-10-01

    An unusual but well-documented presentation of minimal change disease is nephrotic proteinuria and acute renal failure. One pathophysiological mechanism proposed to explain this syndrome is nephrosarca, or severe oedema of the kidney. We describe a patient with minimal change disease who presented with heavy proteinuria and acute renal failure but had no evidence of renal interstitial oedema on biopsy. Aggressive fluid removal did not reverse the acute renal failure. Renal function slowly returned concomitant with resolution of the nephrotic syndrome following corticosteroid therapy. The time profile of the clinical events is not compatible with the nephrosarca hypothesis and suggests an alternative pathophysiological model for the diminished glomerular filtration rate seen in some cases of minimal change disease.

    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)

    2017-09-01

    Kawasaki disease is an acute multisystem childhood vasculitis with a predilection for the coronary arteries. The role of corticosteroids and acetyl salicylic acid (ASA) in the treatment of acute Kawasaki disease are matters of ongoing debate and changing attitudes from one extreme to the other. Recent work has provided new evidence to guide our thinking about these two therapeutic agents, which will be the focus of this review. Corticosteroids are effective and well tolerated in Kawasaki disease, both as initial adjunctive treatment in those at high-risk for poor outcome, and as rescue therapy after failed intravenous immunoglobulin (IVIG).Higher doses of ASA (> 30 mg/kg/day) in the acute phase of Kawasaki disease, have no clear benefit over antiplatelet doses in improving coronary outcome. Corticosteroids should be used in patients at high-risk for poor coronary outcome, and in patients who fail IVIG. The absence of widely applicable and validated risk-scoring systems in Kawasaki disease outside of Japan remains a limiting factor to identify high-risk children. Current evidence does not demonstrate any advantage of high-dose over low-dose ASA in the acute phase of Kawasaki disease, in preventing coronary artery aneurysms.

    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.

    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.

    Abstract The plasma levels of asymmetric dimethylarginine (ADMA) had been proved to be an independent cardiovascular risk factor. Few studies involved the entire arginine methylation dysfunction. This study was designed to investigate whether arginine methylation dysfunction is associated with acute coronary syndrome risk in coronary artery disease population. In total 298 patients undergoing coronary angiography because of chest pain with the diagnosis of stable angina pectoris or acute coronary syndrome from February 2013 to June 2014 were included. Plasma levels of free arginine, citrulline, ornithine, and the methylated form of arginine, ADMA, and symmetric dimethylarginine (SDMA) were measured with high-performance liquid chromatography coupled with tandem mass spectrometry. We examined the relationship between arginine metabolism-related amino acids or arginine methylation index (AMI, defined as ratio of [arginine + citrulline + ornithine]/[ADMA + SDMA]) and acute coronary events. We found that plasma ADMA levels were similar in the stable angina pectoris group and the acute coronary syndrome group (P = 0.88); the AMI differed significantly between 2 groups (P angina and acute coronary syndrome patients; AMI might be an independent risk factor of acute coronary events in coronary artery disease population.

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

    Undernutrition in hospitalised patients is likely to be contributed to by the dual action of the underlying disease and acute catabolism associated with it. The aim of this study was to measure the association between underlying disease and nutritional status in acutely ill older patients. Four hundred and forty-five randomly selected patients had their nutritional status assessed from anthropometric, haematological and biochemical data within 72h of admission, at 6 weeks and at 6 months. Data were also collected on age, disability, chronic illness, medications, smoking and acute-phase response. Patients admitted with chronic obstructive pulmonary disease (COPD), heart failure and falls had significantly lower anthropometric measurements compared with all study populations than for example those admitted with ischaemic heart disease (IHD), chest infections and for elective hip surgery. Nutritional status has deteriorated between admission and 6 weeks among those with COPD, heart failure and falls compared with all study populations. Over 6-months 33 (52%) COPD patients and 14 (39%) heart failure patients were readmitted to hospital compared with 137 (35%) patients of all study populations. Nutritional supplements lead to a limited but significant benefit in transferrin and red cell folate among patients with heart failure and IHD. In older patients, underlying diseases have variable contributions to the poor nutritional status associated with acute illness.

  16. The Role of Echocardiography in Coronary Artery Disease and Acute Myocardial Infarction

    2015-10-01

    Full Text Available Echocardiography is a non-invasive diagnostic technique which provides information regarding cardiac function and hemodynamics. It is the most frequently used cardiovascular diagnostic test after electrocardiography and chest X-ray. However, in a patient with acute chest pain, Transthoracic Echocardiography is essential both for diagnosing acute coronary syndrome, zeroing on the evaluation of ventricular function and the presence of regional wall motion abnormalities, and for ruling out other etiologies of acute chest pain or dyspnea, including aortic dissection and pericardial effusion.Echocardiography is a versatile imaging modality for the management of patients with chest pain and assessment of left ventricular systolic function, diastolic function, and even myocardial and coronary perfusion and is, therefore, useful in the diagnosis and triage of patients with acute chest pain or dyspnea.This review has focused on the current applications of echocardiography in patients with coronary artery disease and myocardial infarction

    2017-01-01

    A 62-year-old man underwent uncomplicated dermofasciectomy of the right little finger. In the week after surgery, he presented with erythema, tenderness, reduced range of movement, and a chalklike discharge from the suture line. Investigations revealed a raised serum urate level accompanied with a borderline rise in inflammatory markers. A diagnosis of acute gout was made. The patient was managed with nonsteroidal anti-inflammatory drugs. Clinicians should consider the diagnosis of gout when patients present after surgery with redness, pain, and swelling and also consider measuring urate levels before surgery and initiating colchicine prophylaxis when there is a known diagnosis of gout before surgery. Accurate diagnosis may prevent unnecessary antibiotic use. Copyright © 2017 American Society for Surgery of the Hand. Published by Elsevier Inc. All rights reserved.

    Full Text Available INTRODUCTION: Antiretroviral drug interventions significantly reduce the risk of HIV transmission to infants through breastfeeding. We report diarrhoea prevalence and all-cause mortality at 12 months of age according to infant feeding practices, among infants born to HIV-infected and uninfected mothers in South Africa. METHODS: A non-randomised intervention cohort study that followed both HIV-infected and HIV-uninfected mothers and their infants until 18 months of age. Mothers were supported in their infant feeding choice. Detailed morbidity and vital status data were collected over the first year. At the time, only single dose nevirapine was available to prevent mother-to-child transmission of HIV. RESULTS: Among 2,589 infants, detailed feeding data and vital status were available for 1,082 HIV-exposed infants and 1,155 HIV non-exposed infants. Among exclusively breastfed (EBF infants there were 9.4 diarrhoeal days per 1,000 child days (95%CI. 9.12-9.82 while among infants who were never breastfed there were 15.6 diarrhoeal days per 1,000 child days (95%CI. 14.62-16.59. Exclusive breastfeeding was associated with fewer acute, persistent and total diarrhoeal events than mixed or no breastfeeding in both HIV-exposed infants and also infants of HIV uninfected mothers. In an adjusted cox regression analysis, the risk of death among all infants by 12 months of age was significantly greater in those who were never breastfed (aHR 3.5, p<0.001 or mixed fed (aHR 2.65, p<0.001 compared with those who were EBF. In separate multivariable analyses, infants who were EBF for shorter durations had an increased risk of death compared to those EBF for 5-6 months [aHR 2.18 (95% CI, 1.56-3.01; p<0.001]. DISCUSSION: In the context of antiretroviral drugs being scaled-up to eliminate new HIV infections among children, there is strong justification for financial and human resource investment to promote and support exclusive breastfeeding to improve HIV-free survival

  20. Managing the acute painful episode in sickle cell disease

    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。

    McArdle disease typically presents in childhood or young adults with myalgia, exercise intolerance, cramps and myoglobinuria. Deficiency of myophosphorylase enzyme results in inability to degrade glycogen stores, causing glycogen accumulation in muscle tissue and energy deficit. Evolution with rhabdomiolysis may occur and can be complicated with acute kidney injury but rarely, in about 11% of cases, is the initial disease manifestation. We report a case of McArdle Disease in a 38-year-old male patient. The disease went unrecognized despite previous symptoms (myalgia, exercise intolerance and single myoglobinuria episode) until an episode of rhabdomyolisis complicated with oliguric acute kidney injury requiring hemodialysis. The kidney biopsy showed evidence of acute tubular necrosis. Despite normalization of renal function, muscle lysis markers remained abnormal. Metabolic myopathy was suspected and a muscle biopsy was performed. It showed subsarcolemic glycogen deposition and absence of myophosphorylase activity. This case-report underlines the importance of considering metabolic myopathy in patients with acute kidney injury and severe rhabdomyolisis.

    2000-01-01

    Previous findings of cognitive deficits and EEG slowing in Alzheimer's patients, together with independent reports of the performance enhancing and electrocortical activating properties of nicotine in normal adults, stimulated this study to examine the acute effects of nicotine on spectrum-analyzed EEG in patients with dementia of the Alzheimer type (DAT). Thirteen patients, 6 currently receiving cholinesterase inhibitor treatment and the remaining being medication free, were administered 2 mg of nicotine polacrilex under randomized, placebo-controlled conditions. Compared to age-regressed EEG norms, the pretreatment EEG spectrums of patients in general were characterized by excessive slow (delta and theta)-wave power, diminished fast (alpha and beta)-wave power and slow mean alpha and total band frequencies. Although postnicotine EEG indices remained within the abnormal range, nicotine, compared to placebo, significantly shifted EEG towards normal values by reducing slow wave (relative delta and theta) power and augmenting fast (relative alpha-1, alpha-2, beta-1) wave power. No differences were observed between treated and nontreated patients in response to nicotine. The results are discussed in relation to cholinergic and brain arousal systems and their relationship to cognitive processes.

    Wilson's disease is a rare disorder of copper transport in hepatic cells, and may present as cholestatic liver disease; pancreatitis and cholangitis are rarely associated with Wilsons's disease. Moreover, cases of Wilson's disease presenting as pigmented gallstone pancreatitis have not been reported in the literature. In the present report, we describe a case of a 37-year-old man who was admitted with jaundice and abdominal pain. The patient was diagnosed with acute pancreatitis, cholangitis, and obstructive jaundice caused by pigmented gallstones that were detected during retrograde cholangiopancreatography. However, because of his long-term jaundice and the presence of pigmented gallstones, the patient underwent further evaluation for Wilson's disease, which was subsequently confirmed. This patient's unique presentation exemplifies the overlap in the clinical and laboratory parameters of Wilson's disease and cholestasis, and the difficulties associated with their differentiation. It suggests that Wilson's disease should be considered in patients with pancreatitis, cholangitis, and severe protracted jaundice caused by pigmented gallstones.

    2015-03-01

    In patients with acute coronary syndrome (ACS), early management is of prime importance. However, the median time taken by the patient to call the emergency services is often very long, up to 2 hours. The presence of a physician as first responder ensures good quality resuscitation in case of cardiac arrest, and allows recording of a first ECG, which can be very informative, especially in ACS without ST segment elevation. Treatment at this stage is limited to sublingual nitroglycerin and aspirin. If the first ECG shows ST segment elevation, the patient should be immediately oriented for reperfusion, usually by percutaneous coronary intervention. in the absence of ST segment elevation, the diagnosis of ACS remains unconfirmed. This does not imply that the risk is lesser, but rather that the risk cannot be evaluated accurately in the pre-hospital setting. The use of risk scores can guide the choice of management towards an invasive strategy, including coronary angiography (immediately, or within 24-72 hours). Low-risk patients are candidates for an invasive strategy, provided non-invasive tests demonstrate the presence of ischemia. During the hospital phase, antiplatelet treatment should be initiated and must be adapted to the patient bleeding and thrombotic risk. Clopidogrel is recommended only in patients who are not amenable to prasugrel or ticagrelor. Statin therapy should be initiated from day one, regardless of the initial cholesterol level, preferably with 80 mg atorvastatin. Angiotensin-converting enzyme inhibitors and beta-blockers should also be prescribed to complete the medical prescription both in-hospital and in the long term.

    The aim of the present study was to evaluate the oxidative stress level and antioxidant trace elements status associated with lower airway disease in draft horses. For this purpose, venous blood samples were obtained from draft horses exhibiting signs of lower respiratory tract disorders (n = 83) and from control group (n = 20). Serum trace elements including selenium (Se), copper (Cu), zinc (Zn), manganese (Mn), and iron (Fe) were assayed. Serum malondialdehyde (MDA) and low-density lipoprotein (LDL) levels as well as plasma hydrogen peroxides (H₂O₂) concentration and activity of plasma glutathione reductase (GR), glutathione-S-transferase (GST) and catalase (CAT) were measured. There was a significant (p horses compared with healthy ones, but the Cu/Zn ratio and Mn were increased (p horses compared with acute cases, but Mn was increased (p horses. However, there was a significant (p horses with chronic respiratory disease compared to acute cases, but CAT activity was decreased (p horses with acute lower airway disease, there was a negative correlation between GR and H₂O₂ (r = -0.458), and LDL and CAT (r = -0.816). However, in chronic disease, a negative correlation was recorded between Se and MDA (r = -0.590). The results of the present study indicate that oxidative stress, with alteration of antioxidant trace element levels, is a feature of respiratory disease in draft horses.

    Full Text Available Abstract Graft versus host disease (GVHD is an uncommon complication after orthotopic liver transplantation (OLT with an incidence of 0.1–2%, but an 80–100% mortality rate. Patients can present with skin rashes, diarrhea, and bone marrow aplasia between two to eight weeks after OLT. Diagnosis of GVHD is made based on clinical and histologic evidence, supported by chimerism studies showing donor HLA alleles in the recipient bone marrow or blood. Several therapeutic approaches have been used for the management of GVHD after OLT including increased immunosuppression, decreased immunosuppression, and cellular therapies. However, success rates have been low, and new approaches are needed.

    The aim of this study was to evaluate the oxidant profile and iron metabolism in serum of dogs infected by Ehrlichia canis. Banked sera samples of dogs were divided into two groups: negative control (n = 17) and infected by E. canis on acute (n = 24), and subclinical (n = 18) phases of the disease. The eritrogram, leucogram, and platelet counts were evaluate as well as iron, ferritin, and transferrin levels, latent iron binding capacity (LIBC), and transferrin saturation index (TSI) concentration. In addition, the advanced oxidation protein products (AOPP) and ferric reducing ability of plasma (FRAP) in sera were also analyzed. Blood samples were examined for the presence of E. canis by PCR techniques. History and clinical signals were recorded for each dog. During the acute phase of the disease, infected animals showed thrombocytopenia and anemia when compared to healthy animals (P canis showed changes in the iron metabolism and developed an oxidant status in consequence of disease pathophysiology.

    Acute psychological stress causes a number of physiologic responses that can trigger acute coronary syndromes in individuals with silent coronary artery disease. The mechanisms behind this phenomena have been the subject of much speculation. The following is a case report and brief review of the literature. A PubMed search was undertaken using the key words stress and myocardial infarction, stress and ischemia, mental stress and coronary artery disease, psychological stress and acute coronary syndrome, and mental stress and plaque destabilization. Articles were restricted to the English language and those dating through December 2007. Acute coronary syndrome is thought to be the end result of a complex mechanism involving platelet activation and endothelial dysfunction. Several studies have shown that acute mental stress leads to enhanced platelet activation and endothelial dysfunction. The mechanism behind this involves both the autonomic nervous system and the neuroendocrine response. Acute psychological stress may lead to acute coronary syndromes in patients with previously silent disease. Physicians should inquire about cardiac symptoms in patients with cardiac risk factors who are experiencing psychological distress. Further research will hopefully lead to an improved understanding of the mechanism behind this process to improve therapeutic interventions.

    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

    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

    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.

    Full Text Available Erdheim-Chester disease (ECD is a non-Langerhans’ histiocytosis and a very rare multisystemic disease of unknown aetiology, with skeletal involvement of the long bones and in more than 50% of cases with extraskeletal involvement. The disease was described in 1930 by the anatomopathologist Jakob Erdheim and his student William Chester. More than 500 cases have since been reported. We report the case of a 77-year-old Italian woman with ECD who was admitted to hospital for acute cardiac tamponade. The patient presented with simultaneous cutaneous, retro-orbital, skeletal, cerebral and cardiovascular manifestations and was successfully treated with corticosteroids followed by interferon.

    X-linked Charcot-Marie-Tooth disease (CMTX1) is a clinically heterogeneous hereditary motor and sensory neuropathy with X-linked transmission. Common clinical manifestations of CMTX1 disease, as in other forms of Charcot-Marie-Tooth (CMT) disease, are distal muscle wasting and weakness, hyporeflexia, distal sensory disturbance, and foot deformities. Mutations in the connexin-32 gene (gap junction protein β1 [GJB1]) are responsible for CMTX1 disease. In this report, we describe a patient with CMTX1 disease presenting with recurrent attacks of transient and episodic acute demyelinating encephalomyelitis (ADEM)-like symptoms without previous signs of lower extremity weakness or foot deformities; the patient, as well as his asymptomatic mother, exhibited a novel GJB1 mutation (p.Met1Ile). Differential diagnosis of recurrent and transient ADEM-like illness, if unexplained, should include the possibility of CMTX1 disease. Copyright © 2014 by the American Academy of Pediatrics.

    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.

    In addition to organovascular arterial ischemic diseases (cardiovascular, vasculovascular, neurovascular, extre-mitovascular, renovascular, genitovascular, bronchopulmovascular, mesenteriovascular, osteoarthromusculovascular, dermovascular, oculovascular, otovascular, stomatovascular etc.), aortic diseases contribute to the wide spectrum of arterial diseases: aortic aneurysms (AA), acute aortic syndromes (AAS) including aortic dissection (AD), intramural haematoma (IMH), penetrating atherosclerotic ulcer (PAU) and traumatic aortic injury (TAI), pseudoaneurysm, aortic rupture, atherosclerosis, vasculitis as well as genetic diseases (e.g. Turner syndrome, Marfan syndrome, Ehlers-Danlos syndrome) and congenital abnormalities including the coarctation of the aorta (CoA). Similarly to other arterial diseases, aortic diseases may be diagnosed after a long period of subclinical development or they may have an acute presentation. Acute aortic syndrome is often the first sign of the disease, which needs rapid diagnosis and decisionmaking to reduce the extremely poor prognosis. Key clinical-etiology-anatomy-patophysiology (CEAP) diagnostic aspects of aortic diseases are discussed in this document (project Vessels).

    Maple syrup urine disease is a common amino acids metabolic disease. In most patients, onset occurs in the neonatal period and infancy. In this study, the case of a school boy with acute encephalopathy due to late-onset maple syrup urine disease is summarized. The boy (8.5 years) was admitted because of acute encephalopathy after suffering from infection for two days at the age of eight and a half years. Metabolic acidosis, hyperuricemia and decreased protein level in cerebrospinal fluid were found by general laboratory tests. Magnetic resonance imaging of the brain revealed signal intensity abnormalities in the bilateral cerebellum dentate nucleus, brainstem, thalamus, putamen, caudate nucleus and cortex of the cerebral hemispheres. On T1WI and T2WI scanning, hyperintensive signal was found. Blood leucine and valine were significantly elevated. Urinary 2-hydroxy isovaleric acid, 3-hydroxybutyric acid, 2-keto isovaleric acid, and 2-keto acid also increased. Both the blood amino acid and urine organic acid profiles led to the diagnosis of maple syrup urine disease. In the acute period, the patient was treated with a large dose of vitamin B1, glucose, L-carnitine and a protein-restrict diet. The patient's condition improved significantly after five days of treatment, and he recovered completely two days later. Afterwards, treatment with vitamin B1, L-carnitine and a protein-restrict diet (1 g/kg/day) was continued. One and a half months later, blood amino acids and urine organic acids returned to normal. Magnetic resonance imaging of the brain also indicated a great improvement. It was concluded that inborn metabolic disease should be considered in the patients with an onset similar to acute encephalopathy. Early diagnosis and proper treatment can prevent brain damage and improve prognosis.

    Full Text Available Kawasaki disease (KD is one of the most common vasculitis disorders of childhood, affecting predominantly medium-sized arteries, particularly the coronary arteries. For treatment, high-dose intravenous immunoglobulin (IVIG is indicated. IVIG infusions are usually safe and well tolerated even though serious complications can be observed. We present a brief overview of KD and report a two-year-old girl with KD and two IVIG infusions (Gammagard® because of persistent fever after the completion of the first IVIG. Haemolytic anaemia developed after IVIG retreatment. The direct antiglobulin test after haemolysis was positive. The etiology of the haemolysis was related to the presence of transient, passively acquired antibodies that cause a direct antibody-mediated attack. There are few reports of haemolytic anaemia after IVIG infusions. The haemolysis in KD is dose-dependent and occurs more frequently after the second IVIG dose. Non-0 blood group patients are at greater risk. Another factor increasing the risk of haemolysis is also the presence of anaemia due to inflammation in KD.

    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

    Full Text Available Background. Natural history and risk factors for diverticulitis in young patients are still debatable. This study aimed to assess whether difference exists in patients aged 50 and younger when compared to older patients and to identify risk factors for acute diverticulitis in the young. Patients and Methods. From January 2006 to December 2011, 80 patients were admitted to our department for acute diverticulitis. We carried out a cross-sectional study in 23 patients (28.7% aged 50 and younger and 57 older patients (71.3%. Results. Acute diverticulitis in the young was not more aggressive than in the older patient. Diverticulitis at patient’s admission was similar with respect to Hinchey’s stage and prior history of diverticulitis. No significant difference was found for both medical and surgical treatment. The rate of recurrent diverticulitis in nonoperated patients was similar. Male gender, body mass index ≥25, and assumption of alcohol were independent risk factors for the occurrence of an acute diverticulitis in the young. Conclusions. The same disease seems to be affecting young patients such as overweight or obese male individual. Current policies to prevent diverticular disease and its related complications must include obesity control together with high-fiber diet and regular exercise.

    @@ 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.

    Peyronie's disease (PD), defined as the abnormal formation of fibrous plaque(s) in the tunica albuginea of the penis, is a chronic condition that afflicts 3% to 13% of the US male population; there is no current research on the efficacy and safety of collagenase Clostridium histolyticum (CCH) in the treatment of acute phase PD. To examine the efficacy and safety of CCH in the treatment of acute-phase PD. We retrospectively reviewed the records for all patients treated with CCH for PD from April 2014 through April 2017. Patients who reported penile pain and duration of PD no longer than 12 months at presentation qualified as being in the acute phase of PD. The primary outcomes of interest were final changes in curvature after CCH treatment regardless of the number of CCH cycles received and frequency of treatment-related adverse events. Parameters of efficacy and safety were compared between acute- and stable-phase PD. A total of 162 patients were included in the study, of which 36 (22%) qualified as having acute-phase PD (group 1) and the remaining 126 (78%) qualified as having stable-phase PD (group 2). Median duration of PD was 8.5 months (range = 1-12) for group 1 and 18 months (range = 1-492) for group 2. There was no significant difference in final change in curvature between the acute and stable phases of PD (16.7° vs 15.6°; P = .654). There was no statistically significant difference in frequency of treatment-related adverse events between the acute phase (4 patients, 11%) and the stable phase (12 patients, 10%; P = .778). CCH therapy is as safe and efficacious in acute-phase PD as it is in stable-phase PD. This is the first report that assesses the safety and efficacy of CCH therapy focusing on acute-phase PD. This study was composed of a large cohort of patients receiving CCH therapy in acute- and stable-phase PD. Limitations include bias associated with retrospective studies, a small sample, and a single-center setting. Although CCH is not clearly

    Little is presently known about determinants of cardiac illness perceptions, especially regarding psycho-social factors. Questionnaire study among 97 consecutively recruited inpatients (72.2% male; mean age 60.6 years) with acute coronary syndrome. We examined the role of socio-demographic, illness-related and psycho-social factors (Multidimensional Scale of Perceived Social Support, General Self-Efficacy Scale and Life Orientation Test-Revised) for perceived consequences, controllability and causes (Revised Illness Perception Questionnaire) with standard multiple regression. In final models, dispositional pessimism was associated with perceptions of more severe consequences, less personal control and more attribution of illness to immune system factors. Dispositional optimism was associated with less severe perceived consequences. Higher general self-efficacy was associated with less attribution of illness to psychological factors, smoking and poor medical care. Greater perceived social support was associated with higher perceived treatment control and less attribution of illness to immune system factors, poor medical care, chance and accident. Also, gender, educational status, previous heart disease and family history of cardiovascular disease were significantly related to illness perceptions, whereas present disease severity (Global Registry of Acute Coronary Events) was not. Psycho-social resources and illness history were more important determinants of cardiac illness perceptions than present disease severity. This study was supported by unrestricted grants from The FOOD Study Group and The Danish Ministry of Food, Agriculture and Fisheries; The Beckett-Foundation; and The Augustinus Foundation.

    Parasitic infectious diseases acquired in tourist areas may pose a challenge to physicians and to travel medicine practitioners. Acute schistosomiasis may be seen in returning travelers and migrants after primary infection. This form of schistosomiasis is frequently misdiagnosed due to its temporal delay and its nonspecific presentation and might occur even in countries where the disease is endemic, such as in Brazil. The patient developed the acute phase of schistosomiasis with severe clinical manifestations. The quantitative analysis revealed the presence of 240 eggs per gram of stool. The treatment was administered with oxamniquine, and the control of cure of the patient was monitored and was favorable. The present paper aims to emphasize the importance of a detailed clinical history including information regarding travel history.

    The objective of this study was to evaluate the clinical disease, humoral response and viral distribution of recent Porcine rubulavirus (PorPV) isolates in experimentally infected pigs. Four, 6-piglet (5-days old) groups were employed (G1-84, G2-93, G3-147, and G4-T). Three viral strains were used for the experimental infection: the reference strain LPMV-1984 (Michoacán 1984) and two other strains isolated in 2013, one in Queretaro (Qro/93/2013) and the other in Michoacán (Mich/147/2013). Each strain was genetically characterized by amplification and sequencing of the gene encoding hemagglutinin-neuroamidase (HN). The inoculation was performed through the oronasal and ocular routes, at a dose of 1×10(6)TCID50/ml. Subsequently, the signs were evaluated daily and necropsies were performed on 3 different days post infection (dpi). We recorded all micro- and macroscopic lesions. Organs from the nervous, lymphatic, and respiratory system were analyzed by quantifying the viral RNA load and the presence of the infectious virus. The presence of the viral antigen in organs was evidenced through immunohistochemistry. Seroconversion was evaluated through the use of a hemagglutination inhibition test. In the characterization of gene HN, only three substitutions were identified in strain Mich/147/2013, two in strain LPMV/1984 (fourth passage) and one in strain Qro/93/2013, with respect to reference strain LPMV-84, these changes had not been identified as virulence factors in previously reported strains. Neurological alterations associated with the infection were found in all three experimental groups starting from 3dpi. Groups G1-84 and G3-147 presented the most exacerbated nervous signs. Group G2-93 only presented milder signs including slight motor incoordination, and an increased rectal temperature starting from day 5 post infection (PI). The main histopathological findings were the presence of a mononuclear inflammatory infiltrate (lymphocytic/monocytic) surrounding the

    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.

    Full Text Available Acute hemorrhagic edema of infancy is a skin limited leukocytoclastic vasculitis occurring in children younger than 2 years old. Although it has an alarming start, it has a good prognosis. The patients may have a story of drug intake, vaccination or infection. Henoch-Schönlein purpura must be considered in differential diagnosis. With well recognition of this rare disease, the family and the physician’s concern will be prevented; unnecessary investigations and interventions will be reduced.

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

    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.

    Full Text Available Objetive: To describe etanercept use and effectiveness on steroid- refractary acute graft-versus-host disease after hematopoietic cell transplantation. Method: Patients treated with etanercept as off label use for steroid-refractary acute graft-versus-host disease were selected and each patient’s medical history was reviewed to assess the clinical response. Results: The study included five patients: four presented with digestive manifestations and one presented pulmonary and liver manifestations. 80% of patients showed a clinical response: 60% a partial response and 20% a total response. In four cases etanercept 25mg was administered twice a week with variable duration of treatment, achieving no response in 1 case (3 weeks, partial response in two 2 cases (4 weeks and 8 weeks and a complete response in 1 case (8 week period. Only one case was treated with etanercept 50mg administered twice a week for 5 weeks with a partial treatment response. Conclusions: The clinical response rate is consistent with the previously published data. This updates the scarce bibliographic information about etanecept use in steroid-refractary acute graft-versus-host disease. Due to clinical design limitations and the small patient population, future clinical studies should be conducted to assess the efficacy and security of etanercept in these patients.

  11. Guidance Cue Netrin-1 and the Regulation of Inflammation in Acute and Chronic Kidney Disease

    2014-01-01

    Full Text Available Acute kidney injury (AKI is a common problem in the hospital setting and intensive care unit. Despite improved understanding, there are no effective therapies available to treat AKI. A large body of evidence strongly suggests that ischemia reperfusion injury is an inflammatory disease mediated by both adaptive and innate immune systems. Cell migration also plays an important role in embryonic development and inflammation, and this process is highly regulated to ensure tissue homeostasis. One such paradigm exists in the developing nervous system, where neuronal migration is mediated by a balance between chemoattractive and chemorepulsive signals. The ability of the guidance molecule netrin-1 to repulse or abolish attraction of neuronal cells expressing the UNC5B receptor makes it an attractive candidate for the regulation of inflammatory cell migration. Recent identification of netrin-1 as regulators of immune cell migration has led to a large number of studies looking into how netrin-1 controls inflammation and inflammatory cell migration. This review will focus on recent advances in understanding netrin-1 mediated regulation of inflammation during acute and chronic kidney disease and whether netrin-1 and its receptor activation can be used to treat acute and chronic kidney disease.

    2011-06-01

    Changes in the concentration of C-reactive protein (CRP), leukocytes, erythrocyte sedimentation rate, and differential blood count were comparatively estimated in the treatment of 66 infants (aged 1.12 +/- 0.95 years) with acute infectious lung diseases. There was a high correlation between capillary plasma and venous serum CRP concentrations. On the first day of effective antibiotic therapy, there was a significant decrease in CRP levels; the sensitivity and specificity were 96 and 94%, respectively. Thus, measurement of capillary blood CRP is an accessible and informative tool to monitor therapy for infectious lung diseases in infants.

    Patients with Chronic Obstructive Pulmonary Disease (COPD) are frequently hospitalized with an acute exacerbation. Patients with COPD often lose weight. Consequently, deterioration in nutritional status (loss of lean body mass) is a likely repercussion of acute exacerbation in hospitalized COPD patients. The study was carried out to assess the nutritional status of COPD patients with acute exacerbation, during the period of hospital admission, and to evaluate the relationships between the nutritional indices and the pulmonary function parameters. A cross sectional observation study constituting 83 COPD patients consecutively hospitalized with acute exacerbation on accrual during a period of one year. Lung function was measured by routine spirometry. Nutritional status was assessed by the measurement of anthropometric parameters. Hospital outcome was also assessed. Statistical analysis was performed using SPSS version 16.0 Independent t-tests and Pearsons correlation coefficient was used. Mean body weight was 50.03 ± 9.23 kg. Subjects had approximately 5 kg weight loss in previous six months. All the subjects had low BMI (19.38 ± 3.10) and MUAC (21.18 ± 2.31) that was significantly below the predicted levels. The correlation between body weight and FEV(1)/FVC% was good (r = 0.648, p = 0.003). BMI was negatively correlated (r = - 0.0103, p= 0.03) with duration of hospital stay. The high prevalence of malnutrition among hospitalized COPD patients with acute exacerbation is related to their lung function and hospital outcome such as duration of hospital stay.

    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 acute respiratory disease at the time of virus isolation. Two of his family members developed similar symptoms approximately 1 week later and had serological evidence of infection with the same virus. Epidemiological tracing revealed that the family was exposed to a bat in the house approximately 1 week before the onset of the father's clinical symptoms. Genome sequence analysis indicated a close genetic relationship between Melaka virus and Pulau virus, a reovirus isolated in 1999 from fruit bats in Tioman Island, Malaysia. Screening of sera collected from human volunteers on the island revealed that 14 of 109 (13%) were positive for both Pulau and Melaka viruses. This is the first report of an orthoreovirus in association with acute human respiratory diseases. Melaka virus is serologically not related to the different types of mammalian reoviruses that were known to infect humans asymptomatically. These data indicate that bat-borne reoviruses can be transmitted to and cause clinical diseases in humans.

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

    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.

    The pathophysiology of acute kidney injury (AKI) involves multiple and overlapping immunological, biochemical, and hemodynamic mechanisms that modulate the effects of both the initial insult and the subsequent repair. Limited but recent experimental data have revealed that the intestinal microbiota significantly affects outcomes in AKI. Additional evidence shows significant changes in the intestinal microbiota in chronic kidney disease patients and in experimental AKI. In this minireview, we discuss the current status of the effect of intestinal microbiota on kidney diseases, the immunomodulatory effects of intestinal microbiota, and the potential mechanisms by which microbiota can modify kidney diseases and vice versa. We also propose future studies to clarify the role of intestinal microbiota in kidney diseases and to explore how the modification of gut microbiota may be a potential therapeutic tool.

    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.

    Full Text Available Significant left main coronary artery (LMCA stenosis is not rare and reported 3 to 10% of patients undergoing coronary angiography. Unprotected LMCA intervention is a still clinical challenge and surgery is still going to be a traditional management method in many cardiac centers. With a presentation of drug eluting stent (DES, extensive use of IVUS and skilled operators, number of such interventions increased rapidly which lead to change in recommendation in the guidelines regarding LMCA procedures in the stable angina (Class 2a recommendation for ostial and shaft lesion and class 2b recommendation for distal bifurcation lesion. However, there was not clear consensus about the management of unprotected LMCA lesion associated with acute myocardial infarction (MI with a LMCA culprit lesion itself or distinct culprit lesion of other major coronary arteries. Surgery could be preferred as an obligatory management strategy even in the high risk patients. With this review, we aimed to demonstrate treatment strategies of LMCA disease associated with acute coronary syndrome, particularly acute myocardial infarction (MI. In addition, we presented a short case series with LMCA lesion and ST elevated acute MI in which culprit lesion placed either in the left anterior descending artery or circumflex artery. We reviewed the current medical literature and propose simple algorithm for management.

    The aim of this study is to determine the differences in optical coherence tomography angiography (OCTA) features of acute Vogt-Koyanagi-Harada disease (VKH) and acute central serous chorioretinopathy (CSC). Clinical and imaging data of patients with acute CSC and VKH in a tertiary-care institute were analyzed. Multimodal imaging including fluorescein angiography, indocyanine green angiography (ICGA), and enhanced-depth imaging OCT were performed. OCTA images were analyzed for alterations in retinochoroidal microvasculature. Thirty-four eyes (24 patients; 10 with VKH and 14 with CSC) were included. OCTA en face images showed apparent areas of choriocapillaris flow void due to shadowing effect from overlying subretinal fluid and pigment epithelial detachment in CSC. However, eyes with VKH showed presence of true choriocapillaris flow void on OCTA that corresponded to choriocapillaris ischemia on ICGA. OCTA is a useful tool to assess choriocapillaris ischemia in VKH and is helpful to differentiate it from CSC in the acute stage.

    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.

    Upper gastrointestinal bleeding is one of the most frequent causes of morbidity and mortality in the course of liver cirrhosis. People with liver disease frequently have haemostatic abnormalities such as hyperfibrinolysis. Therefore, antifibrinolytic amino acids have been proposed to be used as supplementary interventions alongside any of the primary treatments for upper gastrointestinal bleeding in people with liver diseases. This is an update of this Cochrane review. To assess the beneficial and harmful effects of antifibrinolytic amino acids for upper gastrointestinal bleeding in people with acute or chronic liver disease. We searched The Cochrane Hepato-Biliary Controlled Trials Register (February 2015), Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 2 of 12, 2015), MEDLINE (Ovid SP) (1946 to February 2015), EMBASE (Ovid SP) (1974 to February 2015), Science Citation Index EXPANDED (1900 to February 2015), LILACS (1982 to February 2015), World Health Organization Clinical Trials Search Portal (accessed 26 February 2015), and the metaRegister of Controlled Trials (accessed 26 February 2015). We scrutinised the reference lists of the retrieved publications. Randomised clinical trials irrespective of blinding, language, or publication status for assessment of benefits and harms. Observational studies for assessment of harms. We planned to summarise data from randomised clinical trials using standard Cochrane methodologies and assessed according to the GRADE approach. We found no randomised clinical trials assessing antifibrinolytic amino acids for treating upper gastrointestinal bleeding in people with acute or chronic liver disease. We did not identify quasi-randomised, historically controlled, or observational studies in which we could assess harms. This updated Cochrane review identified no randomised clinical trials assessing the benefits and harms of antifibrinolytic amino acids for upper gastrointestinal bleeding in people with acute or

    The burden of renal disease in human immunodeficiency virus (HIV) and AIDS patients living in Africa is adversely influenced by inadequate socio-economic and health care infrastructures. Acute kidney injury in HIV-positive patients, mainly as a result of acute tubular necrosis, may arise from a combination of hemodynamic, immunological, and toxic insult. A variety of histopathological forms of chronic kidney disease is also seen in HIV patients; HIV-associated nephropathy (HIVAN) and immune complex disease may require different treatment strategies, which at present are unknown. The role of host and viral genetics is still to be defined, especially in relation to the different viral clades found in various parts of the world and within Africa. The arrival and availability of highly active antiretroviral therapy in Africa has given impetus to research into the outcome of the renal diseases that are found in those with HIV. It has also generated a new look into policies governing dialysis and transplantation in this group where previously there were none.

    We report on a male patient with Tuberous Sclerosis Complex (TSC), which was prenatally diagnosed. At the age of 3 months the patient developed acute renal failure with excessive hyperuricemia. Kidney function improved after rehydration and application of rasburicase, however without full recovery. Due to the inappropriate high levels of uric acid compared to kidney function, screening of hypoxanthine-guanine phosphoribosyltransferase (HPRT) related diseases was initiated. Mutation analysis revealed a deletion of exon 2 and 3 of the HPRT gene confirming the diagnosis of Lesch-Nyhan Disease (LND). After initiation of allopurinol therapy renal function further improved. In the following months the patient developed clinically a typical neurological phenotype of LND and TSC with seizures, severe dystonia and developmental delay. Acute renal failure is a rare complication of HPRT related diseases. Combination of two inherited diseases may lead to a delayed diagnosis due to a mixed and maybe misleading phenotype.

    Acute kidney injury (AKI) and fluid overload have been shown to increase morbidity and mortality. The reported incidence of AKI in pediatric patients following surgery for congenital heart disease is between 15% and 59%. Limited data exist looking at risk factors and outcomes of AKI or fluid overload in neonates undergoing surgery for congenital heart disease. Neonates aged 6 to 29 days who underwent surgery for congenital heart disease and who were without preoperative kidney disease were included in the study. The AKI was determined utilizing the Acute Kidney Injury Network criteria. Ninety-five neonates were included in the study. The incidence of neonatal AKI was 45% (n = 43), of which 86% had stage 1 AKI. Risk factors for AKI included cardiopulmonary bypass time, selective cerebral perfusion, preoperative aminoglycoside use, small kidneys by renal ultrasound, and risk adjustment for congenital heart surgery category. There were eight mortalities (five from stage 1 AKI group, three from stage 2, and zero from stage 3). Fluid overload and AKI both increased hospital length of stay and postoperative ventilator days. To avoid increased risk of morbidity and possibly mortality, every attempt should be made to identify and intervene on those risk factors, which may be modifiable or identifiable preoperatively, such as small kidneys by renal ultrasound. © The Author(s) 2015.

    Several neurological manifestations of Lyme disease, both central and peripheral, have been described. Reported here is a case of acute transverse myelitis related to a Lyme neuroborreliosis that presented with isolated acute urinary retention and no lower-extremity impairment. This case, documented by urodynamic and electrophysiological investigations, partially resolved after 6 weeks of intravenous ceftriaxone, affording the removal of the indwelling catheter. Alpha blocker therapy was needed for 3 months, until the complete normalisation of urodynamic and electrophysiological records. This case study indicates that whenever urinary retention is encountered associated with acute transverse myelitis or alone, the patient should be investigated for Lyme disease.

    In 14 patients with unilateral cerebrovascular disease, regional cerebral blood flow (CBF) to distant areas in the acute and chronic stages was evaluated by SPECT with {sup 123}I-IMP. In the acute stage, rCBF in distant areas was decreased in all patients. In the chronic stage, a decrease in rCBF was observed in the contralateral cerebellar hemisphere in 50% of unilateral cerebral hemispheric lesions, in the ipsilateral thalamus in 42.9% of cerebral cortical lesions, and in the ipsilateral cortex in 57.1% of subcortical lesions. The decreased rCBF in distant areas even in the chronic stage suggested the involvement of organic changes in the pathologic condition in this stage. (author)

    Noninvasive ventilation (NIV) with conventional therapy improves the outcome of patients with acute respiratory failure due to hypercapnic decompensation of chronic obstructive pulmonary disease (COPD) or acute cardiogenic pulmonary edema (ACPE). This review summarizes the main effects of NIV in these pathologies. In COPD, NIV improves gas exchange and symptoms, reducing the need for endotracheal intubation, hospital mortality and hospital stay compared with conventional oxygen therapy. NIV may also avoid reintubation and may decrease the length of invasive mechanical ventilation. In ACPE, NIV accelerates the remission of symptoms and the normalization of blood gas parameters, reduces the need for endotracheal intubation, and is associated with a trend towards lesser mortality, without increasing the incidence of myocardial infarction. The ventilation modality used in ACPE does not affect the patient prognosis.

    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.

    Full Text Available Brain dopamine is critically involved in movement control, and its deficiency is the primary cause of motor symptoms in Parkinson disease. Here we report development of an animal model of acute severe dopamine deficiency by using mice lacking the dopamine transporter. In the absence of transporter-mediated recycling mechanisms, dopamine levels become entirely dependent on de novo synthesis. Acute pharmacological inhibition of dopamine synthesis in these mice induces transient elimination of striatal dopamine accompanied by the development of a striking behavioral phenotype manifested as severe akinesia, rigidity, tremor, and ptosis. This phenotype can be reversed by administration of the dopamine precursor, L-DOPA, or by nonselective dopamine agonists. Surprisingly, several amphetamine derivatives were also effective in reversing these behavioral abnormalities in a dopamine-independent manner. Identification of dopamine transporter- and dopamine-independent locomotor actions of amphetamines suggests a novel paradigm in the search for prospective anti-Parkinsonian drugs.

    In this paper we analyze the results of diagnosis and treatment of 130 patients with acute surgical diseases of the abdominal cavity, complicated by peritonitis. We proposed the method of estimating the severity of the patients using a coefficient of status severity (C(SS)), developed a scale for prediction of complicated outcomes of acute surgical pathology of the abdominal cavity and abdominal sepsis, which is adapted to the working conditions of local clinics. Using the C(SS) and the scale prediction, allowed timely identification of patients' risk group with possible complicated course, assign adequate treatment, reduce postoperative complications by 5%, relaparotomies by 4.4%, decrease postoperative mortality by 3.9%.

    Wilson disease (WD) is one of the few inherited but treatable disorder mainly affecting the liver and brain resulting in severe disability or death if left untreated. Hence, it is important to keep a high index of suspicion for diagnosing this clinical entity in appropriate clinical settings. The clinical presentation can be quite variable and they may present solely with neurological features sans hepatic symptoms. Such neurological manifestations usually follow subacute to chronic course. Acute onset anarthria as the heralding and predominant presenting feature has been rarely reported in the literature. We reported a case of a 12-year-old girl who presented with acute onset anarthria and dystonia of 1-month duration. On further evaluation, a diagnosis of WD was made. The patient showed partial improvement after she was started on copper chelating agents and anticholinergics.

    A 68-year-old woman with Parkinson disease (PD) presented with acute monoplegia of her left upper extremity after the neck and limb immobilization for several hours. Her sensory function was normal, and the chest X-ray showed left phrenic nerve palsy. Electrophysiological studies showed multi-segment muscle involvement (C3 to T1) including denervation potentials and reduced interference of motor units in needle electromyography. M wave amplitude in peripheral nerve stimulation was preserved except for the ulnar nerve, suggesting both axonal injury and conduction block at the anterior spinal roots. The patient showed fair recovery in several months, suggesting sufficient reinnervation and recovery of conduction block. Incomplete root avulsion was thought to be the pathomechanism of acute cervical motor radiculopathy.

    Full Text Available Abstract Background Acute diarrhoea is a major cause of childhood morbidity and mortality in sub-Saharan Africa. Its microbiological causes and clinico-epidemiological aspects were examined during the dry season 2005/6 in Tamale, urban northern Ghana. Methods Stool specimens of 243 children with acute diarrhoea and of 124 control children were collected. Patients were clinically examined, and malaria and anaemia were assessed. Rota-, astro-, noro- and adenoviruses were identified by (RT- PCR assays. Intestinal parasites were diagnosed by microscopy, stool antigen assays and PCR, and bacteria by culturing methods. Results Watery stools, fever, weakness, and sunken eyes were the most common symptoms in patients (mean age, 10 months. Malaria occurred in 15% and anaemia in 91%; underweight (22% and wasting (19% were frequent. Intestinal micro-organisms were isolated from 77% of patients and 53% of controls (P P = 0.02. Conclusion Rotavirus-infection is the predominant cause of acute childhood diarrhoea in urban northern Ghana. The abundance of putative enteropathogens among controls may indicate prolonged excretion or limited pathogenicity. In this population with a high burden of diarrhoeal and other diseases, sanitation, health education, and rotavirus-vaccination can be expected to have substantial impact on childhood morbidity.

    Chronic obstructive pulmonary disease (COPD) imposes a costly burden on healthcare. Pulmonary rehabilitation (PR) is the best practice to better manage COPD to improve patient outcomes and reduce acute hospital care utilization. To evaluate the impact of a once-weekly, eight-week multidisciplinary PR program as an integral part of the COPD chronic disease management (CDM) Program at Kyabram District Health Services. The study compared two cohorts of COPD patients: CDM-PR Cohort (4-8 weeks) and Opt-out Cohort (0-3 weeks) between February 2006 and March 2007. The CDM-PR Program involved multidisciplinary patient education and group exercise training. Nonparametric statistical tests were used to compare acute hospital care utilization 12 months before and after the introduction of CDM-PR. The number of patients involved in the CDM-PR Cohort was 29 (n = 29), and that in the Opt-out Cohort was 24 (n = 24). The CDM-PR Cohort showed significant reductions in cumulative acute hospital care utilization indicators (95% emergency department presentations, 95% inpatient admissions, 99% length of stay; effect sizes = 0.62-0.66, P indicators were statistically insignificant for the Opt-out Cohort (emergency department presentations decreased by 5%, inpatient admissions decreased by 12%, length of stay increased by 30%; effect size = 0.14-0.40, P > 0.05). Total costs associated with the hospital care utilization decreased from $130,000 to $7,500 for the CDM-PR Cohort and increased from $77,700 to $101,200 for the Opt-out Cohort. Participation in the CDM-PR for COPD patients can significantly reduce acute hospital care utilization and associated costs in a small rural health service.

    Acute kidney injury (AKI) is a very common complication after allogeneic bone marrow transplantation (BMT) and associated with poor prognosis. Generally kidneys are assumed to be no direct target of Graft-versus-Host Disease (GvHD), and renal impairment is often attributed to several other factors occurring in the early phase after BMT. Our study aimed to prove the existence of renal GvHD in a fully MHC-mismatched model of BALB/c mice conditioned and transplanted according to two different intensity protocols. Syngeneically transplanted and untreated animals served as controls. 4 weeks after transplantation, allogeneic animals developed acute GvHD that was more pronounced in the high-intensity protocol (HIP) group than in the low-intensity protocol (LIP) group. Urea and creatinine as classic serum markers of renal function could not verify renal impairment 4 weeks after BMT. Creatinine levels were even reduced as a result of catabolic metabolism and loss of muscle mass due to acute GvHD. Proteinuria, albuminuria, and urinary N-acetyl-beta-Dglucosaminidase (NAG) levels were measured as additional renal markers before and after transplantation. Albuminuria and NAG were only significantly increased after allogeneic transplantation, correlating with disease severity between HIP and LIP animals. Histological investigations of the kidneys showed renal infiltration of T-cells and macrophages with endarteriitis, interstitial nephritis, tubulitis, and glomerulitis. T-cells consisted of CD4+, CD8+, and FoxP3+ cells. Renal expression analysis of allogeneic animals showed increases in indoleamine-2,3 dioxygenase (IDO), different cytokines (TNFα, IFN-γ, IL-1α, IL2, IL-6, and IL-10), and adhesion molecules (ICAM-1 and VCAM-1), resembling findings from other tissues in acute GvHD. In summary, our study supports the entity of renal GvHD with histological features suggestive of cell-mediated renal injury. Albuminuria and urinary NAG levels may serve as early markers of renal

    An analysis of 321 case notes of patients with Wilson's disease seen between 1955 and 2000 and one case seen in 1949 has revealed that 22 patients presented with a haemolytic crisis. This study was not a specific research project but a retrospective analysis of 321 patients with Wilson's disease seen between 1949 and 2000. All investigations were carried out in the best interests of diagnosis and management of patients referred to my clinic. The delay in diagnosis in 18 cases resulted in progression to severe hepatic disease in 14 cases and to neurological disease in 4 cases. One patient had no symptoms at the time her sister's illness was diagnosed as Wilson's disease. In a second patient, with liver disease, the diagnosis was also made when a sister was found to have Wilson's disease. There was a female to male ratio of 15:7. The average age of onset was 12.6 years and the incidence 6.9%. Delay in diagnosis resulted in nine deaths. Three patients, late in the series, were admitted in the acute phase, two female and one male; of these two responded to chelation therapy, the third required liver transplantation. Haemolysis appeared to be extravascular, and possible mechanisms of the haemolysis are discussed.

    Nitric oxide, when combined with superoxide, produces peroxynitrite, which is known to be an important mediator for a number of diseases including various liver diseases. Peroxynitrite can modify tyrosine residue(s) of many proteins resulting in protein nitration, which may alter structure and function of each target protein. Various proteomics and immunological methods including mass spectrometry combined with both high pressure liquid chromatography and 2D PAGE have been employed to identify and characterize nitrated proteins from pathological tissue samples to determine their roles. However, these methods contain a few technical problems such as low efficiencies with the detection of a limited number of nitrated proteins and labor intensiveness. Therefore, a systematic approach to efficiently identify nitrated proteins and characterize their functional roles is likely to shed new insights into understanding of the mechanisms of hepatic disease pathophysiology and subsequent development of new therapeutics. The aims of this review are to briefly describe the mechanisms of hepatic diseases. In addition, we specifically describe a systematic approach to efficiently identify nitrated proteins to study their causal roles or functional consequences in promoting acute and chronic liver diseases including alcoholic and nonalcoholic fatty liver diseases. We finally discuss translational research applications by analyzing nitrated proteins in evaluating the efficacies of potentially beneficial agents to prevent or treat various diseases in the liver and other tissues.

    Ulinastatin, a trypsin inhibitor, is useful as a first-line or a second-line treatment regimen including alternative therapy for IVIG-resistant or IVIG nonresponder Kawasaki disease (KD) patients. Mechanisms involving protections against tissue organs and endthelial cell and anti-inflammatory effects by ulinastatin, are dependent on the inhibition of PMN-derived elastase, tumor necrosis factor alpha (TNFalpha), and other proinflammatory cytokines/interleukins(IL-1, IL-6, IL-8). Ulinastatin also suppresses the activation of PMN cells, macrophages, and platelets. Although almost no statistical data related to the definitive effect in acute stage of KD, ulinastatin have shown possible effects, but not always, in a part of KD patients. The indications of clinical use include shock and pancreatitis. Off-label uses of ulinastatin have been reported in hematological, hepatic, renal, OB/Gy diseases and cardiovascular diseases including vasculitis syndromes. The efficacy of ulinastatin in aKD remained to be investigated.

    Obesity is a well-recognized risk factor for gallstone formation and increases the risk for gallstone-related complications. Pancreatic diseases are impacted adversely by obesity. Although weight loss surgery increases the risk of gallstone disease, evidence suggests that bariatric surgery mitigates the obesity-associated adverse prognostication in acute pancreatitis. Obesity is also a significant risk factor for pancreatic cancer. Obesity is a global epidemic and is increasing worldwide and among all age groups. There is an urgent need for focused health policies aimed at reducing the incidence and prevalence of obesity. This article summarizes the current literature highlighting the association between obesity and the pathophysiology and outcome of gallstone disease, pancreatitis, and pancreatic cancer.

    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.

    Full Text Available As per World Health Organization estimates, acute diarrhoeal diseases and respiratory infections are the leading causes of death among children1. Diarrhoeal diseases kill nearly 2 million children every year2. Repeated diarrhoeal episodes during childhood and adolescence can lower the fitness and productivity during adulthood3. The main source of diarrhoeal pathogens is the human faeces and for transmission of these faecal pathogens from one infected host to other contaminated hands plays an important role. Hygiene education and hand washing with soap are proved to be cost effective primary preventive measure for diarrhoeal diseases4.

    Full Text Available ABSTRACT OBJECTIVE To analyze the association between fine particulate matter concentration in the atmosphere and hospital care by acute respiratory diseases in children. METHODS Ecological study, carried out in the region of Grande Vitória, Espírito Santo, in the winter (June 21 to September 21, 2013 and summer (December 21, 2013 to March 19, 2014. We assessed data of daily count for outpatient care and hospitalization by respiratory diseases (ICD-10 in children from zero to 12 years in three hospitals in the Region of Grande Vitória. For collecting fine particulate matter, we used portable samplers of particles installed in six locations in the studied region. The Generalized Additive Model with Poisson distribution, fitted for the effects of predictor covariates, was used to evaluate the relationship between respiratory outcomes and concentration of fine particulate matter. RESULTS The increase of 4.2 µg/m3 (interquartile range in the concentration of fine particulate matter increased in 3.8% and 5.6% the risk of medical care or hospitalization, respectively, on the same day and with six-day lag from the exposure. CONCLUSIONS We identified positive association between outpatient care and hospitalizations of children under 12 years due to acute respiratory diseases and the concentration of fine particulate matter in the atmosphere.

  19. Acute kidney injury and chronic kidney disease: an integrated clinical syndrome.

    Chawla, Lakhmir S; Kimmel, Paul L

    2012-09-01

    The previous conventional wisdom that survivors of acute kidney injury (AKI) tend to do well and fully recover renal function appears to be flawed. AKI can cause end-stage renal disease (ESRD) directly, and increase the risk of developing incident chronic kidney disease (CKD) and worsening of underlying CKD. In addition, severity, duration, and frequency of AKI appear to be important predictors of poor patient outcomes. CKD is an important risk factor for the development and ascertainment of AKI. Experimental data support the clinical observations and the bidirectional nature of the relationships between AKI and CKD. Reductions in renal mass and nephron number, vascular insufficiency, cell cycle disruption, and maladaptive repair mechanisms appear to be important modulators of progression in patients with and without coexistent CKD. Distinction between AKI and CKD may be artificial. Consideration should be given to the integrated clinical syndrome of diminished GFR, with acute and chronic stages, where spectrum of disease state and outcome is determined by host factors, including the balance of adaptive and maladaptive repair mechanisms over time. Physicians must provide long-term follow-up to patients with first episodes of AKI, even if they presented with normal renal function.

    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.

    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.

    Full Text Available Acute phosphate nephropathy (APhN following oral sodium phosphate solution (OSP ingestion as a bowel purgative has been frequently reported. It was recently suggested that APhN could progress to chronic kidney disease (CKD and a history of APhN might be considered as one of the causes of CKD. However, there are few reports proving APhN as a cause of CKD. Here, we report a case of APhN that progressed to CKD, as proven by renal biopsy.

    Full Text Available After more than a decade of preclinical and clinical development, therapeutic infusion of mesenchymal stromal cells is now a leading investigational strategy for the treatment of acute graft-versus-host disease (GVHD. While their clinical use continues to expand, it is still unknown which of their immunomodulatory properties contributes most to their therapeutic activity. Herein we describe the proposed mechanisms, focusing on the inhibitory activity of mesenchymal stromal cells (MSCs at immunologic checkpoints. A deeper understanding of the mechanism of action will allow us to design more effective treatment strategies.

    We present a case of cutaneous acute graft-versus-host disease (aGVHD) with confluent erythematous perifollicular hyperkeratosis and ichthyosiform scale in the clinical pattern of type II (atypical adult) pityriasis rubra pilaris (PRP), which developed 26 days after allogeneic peripheral blood stem cell transplant. Skin histology confirmed features of both aGVHD and PRP. The skin lesions were refractory to oral prednisolone and cyclosporine and only partially responsive to a combination of i.v. methylprednisolone, oral tacrolimus, oral mycophenolate mofetil, and infusions of anti-thymocyte globulin and the tumour necrosis factor-α inhibitor, etanercept. © 2013 The Australasian College of Dermatologists.

    Full Text Available We report on a 16-year old female patient with biopsy proved minimal change disease and steroid state. She was subsequentlygiven cyclosporin for varying periods of time with inadequate response. She developed four episodes of acute renal failure in the background of severe nephrotic state, 10 years after the onset of her illness. Three of these episodes could be reversed with albumin infusion and judicious use of diuretics while the fourth necessitated six sessions of ultrafiltration. In none of the episodes of ARF could we find any cause other than the nephrotic state itself.

    Blast cells from five cases of secondary unclassifiable leukemia following therapy for Hodgkin's disease were studied by cytochemical, immunological and cytogenetic analyses. Cytochemical and immunological reactivity were in accordance with poorly differentiated, myeloid blasts. The four cases in which karyotype analysis was performed showed specific chromosomal abnormalities. No evidence of multiple lineage involvement was found. Problems in classifying these cases of secondary ANLL were due to the high grade of undifferentiation of the blast cells. Their low cytochemical reactivity with markers of myeloid differentiation was similar to what may be observed in patients with acute undifferentiated leukemia or with chronic myeloid leukemia in blast crisis.

    Acute promyelocytic leukemia (APL) is driven by a chromosomal translocation whose product, the PML/retinoic acid (RA) receptor α (RARA) fusion protein, affects both nuclear receptor signaling and PML body assembly. Dissection of APL pathogenesis has led to the rediscovery of PML bodies and revealed their role in cell senescence, disease pathogenesis, and responsiveness to treatment. APL is remarkable because of the fortuitous identification of two clinically effective therapies, RA and arsenic, both of which degrade PML/RARA oncoprotein and, together, cure APL. Analysis of arsenic-induced PML or PML/RARA degradation has implicated oxidative stress in the biogenesis of nuclear bodies and SUMO in their degradation.

    Full Text Available Acute limb ischemia and peripheral vascular disease (PVD are unusual presentations of polyarteritis nodosa (PAN. Here, we present a case with PVD of both lower limbs leading to foot claudication. Digital subtraction angiography showed narrowing, irregularity, and occlusion of both lower limb arteries with no involvement of the abdomen visceral arteries. Based on significant weight loss, diastolic blood pressure >90 mmHg, myalgia, testicular pain, and angiographic abnormalities in medium-sized arteries, he was diagnosed as having PAN. He was treated with corticosteroid and bolus intravenous cyclophosphamide following which he had prompt and near-complete recovery of the symptoms without any tissue loss.

    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

    Impairment of gut mucosal immunity by the transplant process could facilitate translocation of commensal bacteria and thereby augment the graft-versus-host response. To begin to assess the influence of gut mucosal immunity on the development of acute graft-versus-host disease (GVHD), we conducted a prospective study in 24 pediatric allogeneic hematopoietic cell transplant recipients, assessing 4 fecal markers of mucosal immunity: calprotectin, soluble CD8 (sCD8), soluble intracellular adhesion molecule 1, and β-defensin-2. Stool samples were collected prospectively on transplant days 0, +5, +10, and +15 and analyzed by ELISA. Lower levels on day +5 (calprotectin and β-defensin-2) and day +10 (calprotectin, β-defensin-2, and sCD8) were associated with subsequent acute GVHD. The most striking difference was with calprotectin on day +10. Patients with levels below 424 mg/kg had an incidence of 77.8%, whereas those with levels above this threshold had a cumulative incidence of 0% (P = .002). Relative defects in gut mucosal immunity may be important in the pathogenesis of acute GVHD.

    AIM: To analyze the clinical characteristics of patients diagnosed with Fitz-Hugh-Curtis syndrome.METHODS: The clinical courses of patients that visited St. Mary's Hospital with abdominal pain from January 2005 to December 2006 and were diagnosed with Fitz-Hugh-Curtis syndrome were examined.RESULTS: Fitz-Hugh-Curtis syndrome was identified in 22 female patients of childbearing age; their mean age was 31.0 + 8.1 years. Fourteen of these cases presented with pain in the upper right abdomen alone or together with pain in the lower abdomen,and six patients presented with pain only in the lower abdomen. The first impression at the time of visit was acute cholecystitis or cholangitis in 10 patients and acute appendicitis or pelvic inflammatory disease in eight patients. Twenty-one patients were diagnosed by abdominal computer tomograghy (CT), and the results of abdominal sonography were normal for 10 of these patients. Ch/amydia trichomatis was isolated from 18 patients. Two patients underwent laparoscopic adhesiotomy and 20 patients were completely cured by antibiotic treatment.CONCLUSION: For women of childbearing age with acute pain in the upper right abdomen alone or together with pain in the lower abdomen, Fitz-HughCurtis syndrome should be considered during differential diagnosis. Moreover, in cases suspected to be Fitz-HughCurtis syndrome, abdominal c-r, rather than abdominal sonography, assists in the diagnosis.

  13. The Role of Purine Metabolites as DAMPs in Acute Graft-versus-Host Disease

    2016-01-01

    Acute graft-versus-host disease (GvHD) causes high mortality in patients undergoing allogeneic hematopoietic cell transplantation. An early event in the classical pathogenesis of acute GvHD is tissue damage caused by the conditioning treatment or infection that consecutively leads to translocation of bacterial products [pathogen-associated molecular patterns (PAMPs)] into blood or lymphoid tissue, as well as danger-associated molecular patterns (DAMPs), mostly intracellular components that act as pro-inflammatory agents, once they are released into the extracellular space. A subtype of DAMPs is nucleotides, such as adenosine triphosphate released from dying cells that can activate the innate and adaptive immune system by binding to purinergic receptors. Binding to certain purinergic receptors leads to a pro-inflammatory microenvironment and promotes allogeneic T cell priming. After priming, T cells migrate to the acute GvHD target organs, mainly skin, liver, and the gastrointestinal tract and induce cell damage that further amplifies the release of intracellular components. This review summarizes the role of different purinergic receptors in particular P2X7 and P2Y2 as well as nucleotides in the pathogenesis of GvHD.

    This paper analyzes the possible impact of lunar phases on the dynamics of acute cardiovascular diseases: acute myocardial infarctions (MIs) and acute brain strokes (BSs) at different levels of heliogeomagnetic activity. The superposed epoch analysis (SEA) has been applied with dates of the new moon and full moon used as reference days. A statistical analysis of a 14-year-long (1992 to 2005) series of everyday medical data from the Central Clinical Hospital no. 1 of Russian Railways (Moscow) and the parameters of heliogeomagnetic activity was carried out. It was found that daily occurrences of MIs and BSs vary with the phase of the moon. These variations are significant; they continue at different levels of heliogeomagnetic activity and are not related to the variations in geomagnetic activity identified by the same method. The effect of lunar phases on MIs and BSs is quite different. New moons and full moons have qualitatively the same effect on MIs; however, there are significant differences in the incidence of BSs during new moons and full moons.

    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.

    Both alcoholic liver disease (ALD) and nonalcoholic fatty liver disease are characterized by massive lipid accumulation in the liver accompanied by inflammation, fibrosis, cirrhosis, and hepatocellular carcinoma in a substantial subgroup of patients. At several stages in these diseases, mediators of the immune system, such as cytokines or inflammasomes, are crucially involved. In ALD, chronic ethanol exposure sensitizes Kupffer cells to activation by lipopolysaccharides through Toll-like receptors, e.g., Toll-like receptor 4. This sensitization enhances the production of various proinflammatory cytokines such as interleukin-1 (IL-1) and tumor necrosis factor-alpha, thereby contributing to hepatocyte dysfunction, necrosis, and apoptosis and the generation of extracellular matrix proteins leading to fibrosis/cirrhosis. Indeed, neutralization of IL-1 by IL-1 receptor antagonist has recently been shown to potently prevent liver injury in murine models of ALD. As IL-1 is clearly linked to key clinical symptoms of acute alcoholic hepatitis such as fever, neutrophilia, and wasting, interfering with the IL-1 pathway might be an attractive treatment strategy in the future. An important role for IL-1-type cytokines and certain inflammasomes has also been demonstrated in murine models of nonalcoholic fatty liver disease. IL-1-type cytokines can regulate hepatic steatosis; the NLR family pyrin domain containing 3 inflammasome is critically involved in metabolic dysregulation. IL-1 cytokine family members and various inflammasomes mediate different aspects of both ALD and nonalcoholic fatty liver disease.

    Full Text Available Abstract Introduction Crohn's disease (CD can affect any part of the alimentary tract from the mouth to the anus, with most common site being the terminal ileum. Case presentation A child suffering from undiagnosed Crohn disease (CD, presented with an acute abdominal obstruction due to a large pseudopolyp in the jejunoileal area. At laparotomy, a jejunoileal segment of 45 cm, containing multiple areas of damage to the small intestine, was excised and a primary end – to – end anastomosis was performed. Conclusion The coexistence of an intestinal pseudopolyp with undiagnosed Crohn's disease may be the cause of acute abdominal obstruction in children.

    Background Acute exacerbation of chronic obstructive pulmonary disease (COPD) is always associated with a high incidence and mortality. Because of the presence of some concomitant risk factors such as immobilization, bronchial superinfection, patients who are admitted for acute exacerbations of COPD are generally considered to be at moderate risk for the development of venous thromboembolism. In this study, we investigated the prevalence and the clinical manifestations of deep venous thrombosis (DVT) in patients with acute exacerbation of COPD.Methods From March 2007 to March 2009, 520 consecutive patients were included in this study. On admission, color Doppler ultrasound of lower extremities in all cases was performed for diagnosing DVT. Patients with DVT were compared with those without DVT from such aspects as demographics, symptoms, physical signs and risk factors.Results Among the 520 patients, DVT was found in 46 cases (9.7%). In patients with DVT, the duration of hospitalization was longer (P=0.01), and the mechanical ventilation requirement increased (P <0.001). Other indicators for patients with more possibility of DVT were immobility exceeding 3 days (P <0.001); pneumonia as concomitance (P=0.01); respiratory failure type Ⅱ (P=0.013); current smoking (P=0.001). Lower extremity pain was more common in DVT cases in comparison to those without DVT (34.8% vs. 15.2%, P=0.01 ).Conclusions The acute exacerbation of COPD patients, who were immobilized for over 3 days, complicated by pneumonia and had respiratory failure type Ⅱ, had a higher risk of DVT. In addition, DVT detection awareness should be increased in cases that had a lower extremity pain.

    Several thousands of people, including children, suffer from acute respiratory disease (ARD) every year worldwide. Pro-active planning and mitigation for these diseases require identification of the major drivers in a location-specific manner. While the importance of air pollutants in ARD has been extensively studied and emphasized, the role of weather variables has been less explored. With Delhi with its large population and pollution as a test case, we examine the relative roles of air pollution and weather (cold days) in ARD. It is shown that both the number of cold days and air pollution play important roles in ARD load; however, the number of cold days emerges as the major driver. These conclusions are consistent with analyses for several other states in India. The robust association between ARD load and cold days provides basis for estimating and predicting ARD load through dynamical model, as well as impact of climate change.

    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. 2016 BMJ Publishing Group Ltd.

    An outbreak of severe acute respiratory disease characterized by tracheitis and bronchitis was observed in young goslings on a large-scale goose farm in Hungary. Histological examination revealed amphophilic intranuclear inclusion bodies in the superficial epithelial cells of the trachea and bronchi. Adenovirus-like particles were detected by electron microscopy, and the virus isolated from the trachea and the lungs was identified as egg drop syndrome (EDS) virus by serological and genomic examination. The clinical and pathological signs were reproduced by intratracheal administration of the virus isolate to 1-day-old goslings free of EDS antibodies. The presence of EDS virus DNA in different organs of the naturally and experimentally infected goslings was detected by polymerase chain reaction. This is the first report on the involvement of EDS virus in severe respiratory disease of geese.

    2017-07-01

    Full Text Available Atherosclerosis is a lipid driven chronic inflammatory disease underlying the majority of ischemic events such as myocardial infarction or stroke. Clinical management of ischemic events has improved considerably in the past decades. Accordingly, survival rates have increased. Nevertheless, 12% of patients die within 6 months after the initial event. To improve secondary prevention, appropriate risk prediction is key. However, up to date, there is no clinically available routine marker to identify patients at high risk for recurrent cardiovascular events. Due to the central role of inflammation in atherosclerotic lesion progression and destabilization, many studies have focused on the role of circulating inflammatory cells in these processes. This review summarizes the current evidence on the potential of circulating inflammatory cells as biomarkers for recurrent adverse manifestations in acute coronary syndrome and stable coronary artery disease patients.

    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.

    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.

    Inflammatory changes of the intestine leading to acute abdomen could represent a frequent diagnostic challenge for radiologists actively involved in the emergency area. MDCT imaging findings needs to be evaluated considering the clinical history and symptoms and other abdominal findings that could be of help in differential diagnosis. Several protocols have been suggested and indicated in the imaging of patient with acute intestine. However, a CT protocol in which the precontrast scanning of the abdomen is followed by i.v. administration of contrast medium using the 45-55 s delay could be effective for an optimal visualization of the bowel wall. It is important to learn to recognize how the intestine reacts to the injury and how it 'talks', in order to become aware of the different patterns of disease manifestation related to an acute intestinal condition, for an effective diagnosis of active and acute inflammatory bowel disease.

    Ambient particulate air pollution has been linked to cardiovascular disease. Occupational particle exposure levels may be several times higher than ambient levels but has been less studied. The authors investigated the association between occupational exposure to particles and the incidence of ischaemic heart disease (IHD). The cohort included all manual workers in the Swedish national census of 1980 with information on demographic data and occupation. Information on hospital admissions for acute myocardial infarction or other IHDs and cause of death were obtained from nation-wide registers. A job-exposure matrix for exposure to small (1 μm) particles was developed. HRs were calculated with Cox regression with adjustment for sex, age, socioeconomic group and urban/rural residential area. Exposure to small particles was associated with an increased HR for acute myocardial infarction of 1.12 (95% CI 1.09 to 1.15), and HR for exposure to large particles was 1.14 (95% CI 1.10 to 1.18). The association was somewhat stronger for workers exposed to small particles for more than 5 years, 1.21 (95% CI 1.11 to 1.31), but no trend with exposure intensity was found. The risk associated with exposure to small particles was higher among women than among men, 1.30 (95% CI 1.12 to 1.51) and 1.10 (95% CI 1.07 to 1.14), respectively. Findings were essentially similar for other IHDs. This explorative study gives some support to the hypothesis that occupational exposure to particles increases the risk of acute myocardial infarction and other IHD. The findings must be interpreted cautiously due to lack of smoking data.

    The aim of the present study was to evaluate the effects of changes to the autonomic nervous system in mice during the acute phase of Chagas disease, which is an infection caused by the parasite Trypanosoma cruzi. The following types of mice were inoculated with T. cruzi (CHG): wild-type (WT) and vesicular acetylcholine transporter knockdown (KDVAChT) C57BL/6j mice; wild-type non-treated (NT) FVB mice; FVB mice treated with pyridostigmine bromide (PYR) or salbutamol (SALB); and β(2)-adrenergic receptor knockout (KOβ2) FVB mice. During infection and at 18-21 days after infection (acute phase), the survival curves, parasitaemia, electrocardiograms, heart rate variability, autonomic tonus and histopathology of the animals were evaluated. Negative control groups were matched for age, genetic background and treatment. The KDVAChT-CHG mice exhibited a significant shift in the electrocardiographic, autonomic and histopathological profiles towards a greater inflammatory immune response that was associated with a reduction in blood and tissue parasitism. In contrast, the CHG-PYR mice manifested reduced myocardial inflammation and lower blood and tissue parasitism. Similar results were observed in CHG-SALB animals. Unexpectedly, the KOβ2-CHG mice exhibited less myocardial inflammation and higher blood and tissue parasitism, which were associated with reduced mortality. These findings could have been due to the increase in vagal tone observed in the KOβ2 mice, which rendered them more similar to the CHG-PYR animals. In conclusion, our results indicate a marked immunomodulatory role for the parasympathetic and sympathetic autonomic nervous systems, which inhibit both the inflammatory immune response and parasite clearance during the acute phase of experimental Chagas heart disease in mice.

    Thirty-four patients with cerebral infarction and 18 patients with transient ischemic attack were examined by multi-slice spiral CT scan, CT perfusion imaging, and CT angiography within 6 hours after onset. By CT perfusion imaging, 29 cases in the cerebral infarction group and 10 cases in the transient ischemic attack group presented with abnormal blood flow perfusion, which corresponded to the clinical symptoms. By CT angiography, various degrees of vascular stenosis could be detected in 41 patients, including 33 in the cerebral infarction group and eight in the transient ischemic attack group. The incidence of intracranial artery stenosis was higher than that of extracranial artery stenosis. The intracranial artery stenosis was located predominantly in the middle cerebral artery and carotid artery siphon, while the extracranial artery stenosis occurred mainly in the bifurcation of the common carotid artery and the opening of the vertebral artery. There were 34 cases (83%) with convict vascular stenosis and perfusion abnormalities, and five cases (45%) with perfusion abnormalities but without convict vascular stenosis. The incidence of cerebral infarction in patients with National Institutes of Health Stroke Scale scores ≥ 5 points during onset was significantly higher than that in patients with National Institutes of Health Stroke Scale scores < 5 points. These experimental findings indicate that the combined application of various CT imaging methods allows early diagnosis of acute ischemic cerebrovascular disease, which can comprehensively analyze the pathogenesis and severity of acute ischemic cerebrovascular disease at the morphological and functional levels.

    Full Text Available The aim of this paper is to present for the first time the functional evaluation of each of the vestibular receptors in the six semicircular canals in a patient diagnosed with Meniere’s disease during an acute attack. A 54-year-old lady was diagnosed with left Meniere’s disease who during her regular clinic review suffers an acute attack of vertigo, with fullness and an increase of tinnitus in her left ear. Spontaneous nystagmus and the results in the video head-impulse test (vHIT are shown before, during, and after the attack. Nystagmus was initially left beating and a few minutes later an upbeat component was added. No skew deviation was observed. A decrease in the gain of the vestibuloocular reflex (VOR and the presence of overt saccades were observed when the stimuli were in the plane of the left superior semicircular canal. At the end of the crisis nystagmus decreased and vestibuloocular reflex returned to almost normal. A review of the different possibilities to explain these findings points to a hypothetical utricular damage.

    A rare case of acute epidural hematoma of the posterior fossa associated with von Willebrand's disease is reported. A 9-year-old boy fell down and hit his occipital region against a floor. Soon after he came home and slept, but three hours later he began to vomit and became drowsiness. He visited our hospital and his Glasgow Coma Scale showed 13 points. CT scan on admission showed acute epidural hematoma of left posterior fossa and contusional hematoma in the right temporal lobe. The bleeding time was over 18 minutes. He had been suspected to be suffering from von Willebrand's disease two years ago. Then fresh blood, fresh frozen plasma and anti-hemophilic globulin were prepared. Ten hours after injury, the operation was begun. Fresh epidural hematoma existed as a clot beyond transverse sinus. During the procedure of dural tenting suture, diffuse bleeding from bone, muscle, subcutaneous tissue and dura occurred and it was difficult to stop the bleeding. By using fresh blood and anti-hemophilic globulin, the bleeding was controlled, and then the operation was achieved. In the postoperative course a new epidural hematoma was found in the left temporal region and a new but asymptomatic retinal hemorrhage was found in his right eye. He was discharged without any neurological deficits 25 days after operation.

    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. Copyright © 2012 Elsevier Ltd. All rights reserved.

    Kawasaki disease (KD) is a disease of unknown cause and the causative agent is most likely to be infectious in nature. To investigate the household transmission pattern of infectious illness and etiology, we thus initiated a prospective case and household study. We enrolled KD cases and their household members from February 2004 to September 2008. The KD cases and their household members accepted questionnaire-based interviews of the contact history, signs of infection, and symptoms to check whether clusters of infectious illness occurred. A total of 142 KD cases and 561 household members were enrolled. Among the 142 KD cases, 136 cases (96%) were typical KD, and six (4%) were atypical KD. Of the 561 household members, 17% were siblings, 46% were parents, 18% were grandparents, and the others were cousins or babysitters. Prior to the onset of their KD illness, 66% (94/142) KD cases had contact with ill household members. On the same day of the onset of KD cases' illness, 4% (6/142) KD cases had household members with illness. After KD cases' disease onset, 70% (100/142) KD cases had at least one other family member with illness. Overall, 61% (343/561) of all the household members had acute infectious illness during KD cases' acute stage, and 92% (130/142) of the families had clusters of infectious illness. A total of 66% KD cases had positive contact with ill household members prior to their disease onset and 92% of families had clusters of infectious illness, so KD is strongly associated with infections.

    Full Text Available Abstract The acute phase protein (APP response is an early systemic sign of disease, detected as substantial changes in APP serum concentrations and most disease states involving inflammatory reactions give rise to APP responses. To obtain a detailed picture of the general utility of porcine APPs to detect any disease with an inflammatory component seven porcine APPs were analysed in serum sampled at regular intervals in six different experimental challenge groups of pigs, including three bacterial (Actinobacillus pleuropneumoniae, Streptococcus suis, Mycoplasma hyosynoviae, one parasitic (Toxoplasma gondii and one viral (porcine respiratory and reproductive syndrome virus infection and one aseptic inflammation. Immunochemical analyses of seven APPs, four positive (C-reactive protein (CRP, haptoglobin (Hp, pig major acute phase protein (pigMAP and serum amyloid A (SAA and three negative (albumin, transthyretin, and apolipoprotein A1 (apoA1 were performed in the more than 400 serum samples constituting the serum panel. This was followed by advanced statistical treatment of the data using a multi-step procedure which included defining cut-off values and calculating detection probabilities for single APPs and for APP combinations. Combinations of APPs allowed the detection of disease more sensitively than any individual APP and the best three-protein combinations were CRP, apoA1, pigMAP and CRP, apoA1, Hp, respectively, closely followed by the two-protein combinations CRP, pigMAP and apoA1, pigMAP, respectively. For the practical use of such combinations, methodology is described for establishing individual APP threshold values, above which, for any APP in the combination, ongoing infection/inflammation is indicated.

    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

    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

    Full Text Available BACKGROUND: Cardiovascular diseases are the leading causes of death worldwide, especially for developed countries. Elevated mortality from cardiovascular diseases has been shown related to extreme temperature. We thus assessed the risk of mortality from cerebrovascular diseases, heart diseases, and ischemic heart disease (IHD in relation to temperature profiles in four subtropical metropolitans (Taipei, Taichung, Tainan, and Kaohsiung from 1994 to 2007 in Taiwan. METHODS: Distributed lag non-linear models were applied to estimate the cumulative relative risks (RRs with confidence intervals of cause-specific mortality associated with daily temperature from lag 0 to 20 days, and specific effect of extreme temperature episodes with PM10, NOx, and O3, and other potential confounders controlled. Estimates for cause-specific mortalities were then pooled by random-effect meta-analysis. RESULTS: Comparing to centered temperature at 27 °C, the cumulative 4-day (lag 0 to 3 risk of mortality was significantly elevated at 31 °C for cerebrovascular diseases (RR = 1.14; 95% CI: 1.00, 1.31 and heart diseases (RR =  1.22; 95% CI: 1.02, 1.46 , but not for IHD (RR =  1.09; 95% CI: 0.99, 1.21. To the other extreme, at 15 °C, the cumulative 21-day (lag 0 to 20 risk of mortality were also remarkably increased for cerebrovascular diseases, heart diseases, and IHD (RRs  =  1.48 with 95% CI: 1.04, 2.12, 2.04 with 95% CI: 1.61, 2.58, and 1.62 with 95% CI: 1.30, 2.01, respectively. Mortality risks for cardiovascular diseases were generally highest on the present day (lag 0 of extreme heat. No particular finding was detected on prolonged extreme temperature event by pooling estimations for cause-specific mortality. CONCLUSIONS: Low temperature was associated with greater risk of mortality from cardiovascular diseases in comparison with that of high temperature. Adverse effects of extreme temperatures are acute at the beginning of exposure.

    Full Text Available Cytogenetically normal acute myeloid leukemia (CN-AML patients harboring RUNX1 mutations have a dismal prognosis with anthracycline/cytarabine-based chemotherapy. We aimed to develop an in vivo model of RUNX1-mutated, CN-AML in which the nature of residual disease in this molecular disease subset could be explored. We utilized a well-characterized patient-derived, RUNX1-mutated CN-AML line (CG-SH. Tail vein injection of CG-SH into NOD scid gamma mice led to leukemic engraftment in the bone marrow, spleen, and peripheral blood within 6 weeks. Treatment of leukemic mice with anthracycline/cytarabine-based chemotherapy resulted in clearance of disease from the spleen and peripheral blood, but persistence of disease in the bone marrow as assessed by flow cytometry and secondary transplantation. Whole exome sequencing of CG-SH revealed mutations in ASXL1, CEBPA, GATA2, and SETBP1, not previously reported. We conclude that CG-SH xenografts are a robust, reproducible in vivo model of CN-AML in which to explore mechanisms of chemotherapy resistance and novel therapeutic approaches.

    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 Abstract Background Human caliciviruses (HuCV are emerging enteric pathogens that are a common cause of diarrhea in humans worldwide. Due to the paucity of information on the molecular characterization of HuCV circulating in Mexico, the aim of this work was to investigate the diversity and molecular epidemiology of the HuCV infection associated with acute diarrheal disease in Mexican children aged up to 5 years. Results Of the 131/414 (32% HuCV positive-specimens analyzed, 128 were identified as Norovirus (NoV and three as Sapovirus (SaV. Of the NoV positive specimens, 118/128 (92% were NoV GII and 10/128(8% were untypeable by RT-PCR in both polymerase and capsid genes, whereas one SaV isolate was further confirmed by sequencing as GI.2. Phylogenetic analysis based on polymerase partial gene sequences from 89/131 (68% HuCV isolates showed that 86/89 (97% belong to NoV GII.4 with three main variant clusters of this genotype, 2/89 (2% to NoV GII.2, and 1/89 (1% to SaV GI.2. Furthermore, partial sequencing of the capsid gene VP1 of 63/131 (48% strains indicated that 61/63 (97% correlated with NoV GII.4, whereas only 2/63 (3% clustered to NoV GII.2. HuCV infections were detected throughout the year, and the highest number of cases positive for NoV was found in children between 7 and 18 months of age (60%. Conclusions This study highlights the usefulness of analyzing both polymerase and capsid genes for molecular characterization of HuCV and demonstrates the relatedness and predominance of NoV GII.4 with acute diarrheal disease in young Mexican children, thus contributing to better understanding of the molecular epidemiology of this disease.

    Full Text Available OBJECTIVE: To assess clinical and laboratory features that differentiate acute lymphoblastic leukemia from systemic juvenile idiopathic arthritis at disease onset. METHODS: Fifty-seven leukemia patients with musculoskeletal involvement, without blasts on peripheral blood and without glucocorticoid therapy at disease onset and 102 systemic juvenile idiopathic arthritis patients (International League of Associations for Rheumatology criteria were retrospectively evaluated. The following features were examined: fever, rheumatoid rash, arthritis, limb pain, hepatomegaly, splenomegaly, pericarditis, myocarditis, pleuritis, weight loss, bleeding, anemia, leukopenia, neutropenia, thrombocytopenia, erythrocyte sedimentation rate, and lactic dehydrogenase levels. RESULTS: The median age at disease onset was significantly higher in leukemia patients than in those with systemic-onset juvenile idiopathic arthritis (5.8 vs. 3.8 years. In addition, the frequencies of limb pain, hepatomegaly, weight loss and hemorrhagic manifestations were significantly higher in leukemia patients than in systemic-onset juvenile idiopathic arthritis patients (70% vs. 1%, 54% vs. 32%, 30% vs. 8%, and 9% vs. 0%, respectively. Likewise, the frequencies of anemia, leukopenia, neutropenia, thrombocytopenia and high lactic dehydrogenase levels were statistically higher in leukemia patients than in patients with systemic-onset juvenile idiopathic arthritis (88% vs. 57%, 39% vs. 1%, 60% vs. 1%, 77% vs. 1%, and 56% vs. 14%, respectively. Remarkably, multivariate analysis revealed that limb pain (OR = 553; 95% CI =46.48-6580.42 and thrombocytopenia (OR = 754.13; 95% CI =64.57-8806.72 were significant independent variables that differentiated leukemia from systemic-onset juvenile idiopathic arthritis. The R2 of the Nagelkerke test was 0.91, and the Kaplan-Meier survival curves were similar for acute lymphoblastic leukemia patients with and without limb pain. CONCLUSION: Our study

    We conducted a case-control study of school-age children in Phatthalung, a province in southern Thailand using a questionnaire to investigate associations of children's hygiene-related behavior and hygienic conditions in their homes with acute diarrheal disease. We compared 69 acute diarrhea (less than 7 days duration) cases that attended two hospitals in Phatthalung during August 1995 to June 1996 with 69 age-, sex- and address-matched controls in primary schools who had not suffered from diarrheal disease for the past one year before August 1995. Three factors were found to be significantly associated with acute diarrheal disease: farmer or gum planter as the occupation of father [Odds ratio (OR) 6.6; 95% confidence interval (CI) 1.7-26.1, p water (OR 2.3; CI 0.9-6.1, p water between cases and controls. Considering the data on drinking water, the results indicated that there are some problems with quality of sources of drinking water. The results also suggested that having a refrigerator could have preventive effects on acute diarrheal disease, while inadequate behavior and unhygienic environment in the homes of farmers and gum planters might be related to acute diarrheal among school-age children.

    Upper gastrointestinal bleeding is one of the most frequent causes of morbidity and mortality in the course of liver cirrhosis. Several treatments are used for upper gastrointestinal bleeding in patients with liver diseases. One of them is vitamin K administration, but it is not known whether it benefits or harms patients with acute or chronic liver disease and upper gastrointestinal bleeding. To assess the beneficial and harmful effects of vitamin K for patients with acute or chronic liver disease and upper gastrointestinal bleeding. We searched the Cochrane Hepato-Biliary Group Controlled Trials Register (12 June 2012), the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library (Issue 5 of 12, 2012), MEDLINE (Ovid SP) (1946 to 12 June 2012), EMBASE (Ovid SP) (1974 to 12 June 2012), Science Citation Index EXPANDED (1900 to 12 June 2012), and LILACS (1982 to 19 June 2012). Additional randomised trials were sought from two registries of clinical trials: the Clinical Trials Search Portal of the WHO, and the Metaregister of Controlled Trials. We looked through the reference lists of the retrieved publications and review articles. Randomised clinical trials irrespective of blinding, language, or publication status for assessment of benefits and harms. Observational studies were considered for assessment of harms only. Data from randomised clinical trials were to be summarised by standard Cochrane Collaboration methodologies. We could not find any randomised trials on vitamin K for upper gastrointestinal bleeding in patients with liver diseases in which we could assess benefits and harms. We could not identify quasi-randomised studies, historically controlled or observational studies in which we could assess harms. This updated review found no randomised clinical trials on the benefits and harms of vitamin K for upper gastrointestinal bleeding in patients with liver diseases. The effects of vitamin K need to be tested in randomised clinical

We searched The Cochrane Hepato-Biliary Controlled Trials Register (February 2015), the Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 2 of 12, 2015), MEDLINE (Ovid SP) (1946 to February 2015), EMBASE (Ovid SP) (1974 to February 2015), Science Citation Index EXPANDED (1900 to February 2015), and LILACS (1982 to 25 February 2015). We sought additional randomised trials from two registries of clinical trials: the World Health Organization Clinical Trials Search Portal and the metaRegister of Controlled Trials. We looked through the reference lists of the retrieved publications and review articles. Randomised clinical trials irrespective of blinding, language, or publication status for assessment of benefits and harms. We considered observational studies for assessment of harms only. \\We aimed to summarise data from randomised clinical trials using Standard Cochrane methodology and assess them according to the GRADE approach. We found no randomised trials on vitamin K for upper gastrointestinal bleeding in people with liver diseases assessing benefits and harms of the intervention. We identified no quasi-randomised studies, historically controlled studies, or observational studies assessing harms. This updated review found no randomised clinical trials of vitamin K for upper gastrointestinal bleeding in people with liver diseases. The benefits and harms of vitamin K need to be tested

    The pathogenesis of diffusely adherent Escherichia coli (DAEC) remains to be elucidated. Previously, we found that afimbrial adhesin gene (afa)-positive motile DAEC strains isolated from patients with diarrhoea induce high levels of IL-8 secretion in Caco-2 cells via toll-like receptor 5 (TLR-5), while non-motile strains did not. The aim of this study was to compare virulence properties, including the phylogenetic groups, afa subtypes, IL-8 secretion levels, and the effects on tight junctions, of DAEC strains isolated from healthy persons with those isolated from patients with diarrhoea. Induction of IL-8 secretion in Caco-2 cells was examined for a total of 36 afa-positive strains: 19 from diarrhoeal patients and 17 from healthy carriers. Irrespective of the source, all strains were classified into the phylogenetic group B2 or D, with the exception of two strains. All 7 motile strains isolated from diarrhoeal patients induced high levels of IL-8 secretion, while only 6 of 15 motile strains from healthy carriers induced IL-8 secretion to the same levels as the diarrhoeal strains. We speculated that additional virulence factors other than afa and motility cause the loosening of tight junctions that allows flagellin to reach TLR-5 located on the basolateral side of the epithelium. However, no differences in the TER and dextran permeability were observed between cells infected with diarrhoeal strains and those from healthy persons. Thus, diarrhoeagenic DAEC seems to possess additional factors, in addition to adhesin and flagellin, which can induce high IL-8 secretion.

  10. Early efforts in modeling the incubation period of infectious diseases with an acute course of illness

    Full Text Available Abstract The incubation period of infectious diseases, the time from infection with a microorganism to onset of disease, is directly relevant to prevention and control. Since explicit models of the incubation period enhance our understanding of the spread of disease, previous classic studies were revisited, focusing on the modeling methods employed and paying particular attention to relatively unknown historical efforts. The earliest study on the incubation period of pandemic influenza was published in 1919, providing estimates of the incubation period of Spanish flu using the daily incidence on ships departing from several ports in Australia. Although the study explicitly dealt with an unknown time of exposure, the assumed periods of exposure, which had an equal probability of infection, were too long, and thus, likely resulted in slight underestimates of the incubation period. After the suggestion that the incubation period follows lognormal distribution, Japanese epidemiologists extended this assumption to estimates of the time of exposure during a point source outbreak. Although the reason why the incubation period of acute infectious diseases tends to reveal a right-skewed distribution has been explored several times, the validity of the lognormal assumption is yet to be fully clarified. At present, various different distributions are assumed, and the lack of validity in assuming lognormal distribution is particularly apparent in the case of slowly progressing diseases. The present paper indicates that (1 analysis using well-defined short periods of exposure with appropriate statistical methods is critical when the exact time of exposure is unknown, and (2 when assuming a specific distribution for the incubation period, comparisons using different distributions are needed in addition to estimations using different datasets, analyses of the determinants of incubation period, and an understanding of the underlying disease mechanisms.

    Full Text Available Abstract Background Diarrhoeal disease is a major global health problem, particularly affecting children under the age of 5 years. Besides oral rehydration solution, probiotics are also commonly prescribed to children with acute watery diarrhoea in some settings. Results from randomised clinical trials (RCTs in which investigators studied the effect of probiotics on diarrhoeal symptoms have largely shown a positive effect; yet, the overall quality of the data is limited. In Vietnam, probiotics are the most frequently prescribed treatment for children hospitalised with acute watery diarrhoea, but there is little justification for this treatment in this location. We have designed a RCT to test the hypothesis that an oral preparation of Lactobacillus acidophilus is superior to placebo in the treatment of acute watery diarrhoea in Vietnamese children. Methods This RCT was designed to study the effect of treatment with L. acidophilus (4 × 109 colony-forming units/day for 5 days for acute watery diarrhoea against a placebo in 300 children ages 9 to 60 months admitted to hospitals in Vietnam. Clinical and laboratory data plus samples will be collected on admission, daily during hospitalisation, at discharge, and at follow-up visits for a subset of participants. The primary end point will be defined as the time from the first dose of study medication to the start of the first 24-hour period without diarrhoea as assessed by the on-duty nurse. Secondary endpoints include the time to cessation of diarrhoea as recorded by parents or guardians in an hourly checklist, stool frequency over the first 3 days, treatment failure, rotavirus and norovirus viral loads, and adverse events. Discussion The existing evidence for the use of probiotics in treating acute watery diarrhoea seems to favour their use. However, the size of the effect varies across publications. An array of different probiotic organisms, doses, treatment durations, study populations, designs

    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.

    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.

    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.

    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.

    Erythropoiesis-stimulating agents (ESAs) are effective in ameliorating anemia in chronic kidney disease (CKD). However, a recent trial in diabetic CKD patients suggested a greater stroke risk associated with full correction of anemia using ESAs. We performed a case-control study examining the association of incident ESA use with acute stroke in CKD patients, using national Veterans Affairs data. Patients with eGFR<60 cc/min/1.73m2 and outpatient hemoglobin (Hb)<12g/dL were included. Acute hospitalized stroke cases (N=2071) were identified using diagnosis codes and matched 1:5 to controls without stroke. Conditional logistic regression was used to estimate the association of ESA use with stroke, adjusting for potential confounders. After multivariate adjustment, ESA use (N=1026, 8.3%) was associated with 30% greater odds of stroke (odds ratio[OR]=1.30, 95% confidence interval[CI]: 1.06, 1.58). There was significant interaction (p=.015) between ESA use and cancer; ESA use was associated with 85% greater odds of stroke in cancer patients (95% CI: 1.26, 2.65), but not associated with stroke in patients without cancer (OR=1.07, 95% CI: 0.85, 1.35). ESA-treated patients with cancer received a median initial dose 2.5 to 4 times greater than ESA patients without cancer, but pre-ESA Hb and rate of Hb change did not differ between groups. Among a large national sample of anemic CKD patients, ESA treatment is associated with an increased risk of acute stroke, with the greatest effect among patients with cancer. PMID:21389972

    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.

    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.)

    Thoracic aortic dissection is the most frequent cause of aortic emergency, and unless it is rapidly diagnosed and treated, the result is death. Helical computed tomography (CT) permits the diagnosis of acute aortic dissection with a sensitivity and specificity of nearly 100%. This imaging modality also enables differentiation between proximal aortic dissection (type A in the Stanford classification) and distal aortic dissection (Stanford type B), which are treated differently and have different prognoses. In 70% of patients in whom nontraumatic acute thoracic aortic dissection is diagnosed after evaluation with helical CT, scans show the typical signs of aortic dissection, with rupture and displacement of the intima. CT also can depict other pathologic entities with similar clinical manifestations, such as intramural hematoma and penetrating atherosclerotic ulcer. Awareness of the different radiologic appearances of these disease entities is essential for differential diagnosis. More than one-third of patients with aortic dissection show signs and symptoms indicative of systemic involvement. Because branch-vessel involvement may increase morbidity and mortality, in this group of patients it is important to evaluate the entire aorta so as to determine the distal extent of the dissection and detect any systemic involvement.

    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.

    Rheumatic heart disease (RHD) is an important risk factor for ischemic stroke in developing countries. Observational data on its characteristics and influence on outcome or recurrence of ischemic stroke are scarce. We aimed to investigate proportions, characteristics, functional outcome, and recurrence of acute ischemic stroke patients with RHD in a hospitalized Chinese population. We prospectively enrolled consecutive patients with acute ischemic stroke who were admitted within 1 month of stroke onset from January 2003 to February 2007, into the analysis. Clinical characteristics such as age, gender, risk factors, and National Institutes of Health Stroke Scale on admission were investigated. Basic characteristics, functional outcomes, and recurrence were compared between RHD group and nonRHD group. Of the 1638 cases included, RHD was present in 130 patients (7.9%). RHD patients, compared with those without RHD, were younger, more frequently female, and more often had experienced atrial fibrillation and higher National Institutes of Health Stroke Scale score on admission (all PStroke Scale on admission, the death risk in patients with RHD was 2.0-fold higher at 3 months, 6 months, and 1 year compared with patients without RHD (all PStroke attributable to RHD is still common in the Chinese population. RHD was associated with 2-fold increased risk of death and 1-fold increased risk of recurrence in stroke patients.

    A study of the effects of communal latrines on diarrhoeal incidence and parasite prevalence rates was conducted in 1983 at Tongi, which had five communal Oxfam latrines with a manual flushing system for 924 people; and at Kalsi, which had 39 open fit latrines for 823 people. Inhabitants' stool samples were tested initially and also after twelve months to see the reinfection rates. All inhabitants were dewormed with pyrantel, and were visited weekly to obtain diarrhoea histories. In both communities, there were high prevalence rates of roundworm, hookworm, Trichuris trichiura, Entamoeba histolytica, Giardia lambia and Strongyloides stercoralis. Following the dewormings, the prevalence rates of roundworm, hookworm and Trichuris infection came down significantly, in both areas. The prevalence or reinfection rates remained identical in both communities. There was also no difference in diarrhoea incidence rate for the two areas. It is found that keeping all other variables unchanged, use of communal latrines, without strict disposal of everyone's excreta, does not affect parasite prevalence and diarrhoea rates. People must be educated about the use of communal latrines and the safe disposal of all excreta, including that of children.

Of 118,061 diagnosed HF hospitalizations, 38% received treatment for two or more acute cardiopulmonary conditions (34% for pneumonia, 9% for COPD, 5% for both). Hospitalized older adults diagnosed with pneumonia, COPD, or HF are frequently treated for two or more acute cardiopulmonary conditions, suggesting that clinical syndromes often fall between traditional diagnostic categories. Research is needed to evaluate the risks and benefits of real-world treatment for the many older adults whose presentations elicit diagnostic uncertainty or concern about coexisting acute conditions. © 2016, Copyright the Authors Journal compilation © 2016, The American Geriatrics Society.

    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.

    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.

    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.

    To study the association between fluid overload and acute kidney injury (AKI) after congenital heart disease surgery in infants. A retrospective analysis was performed on 88 infants aged less than 6 months who underwent a radical surgery for congenital heart disease. The treatment outcomes were compared between the infants with AKI after surgery and those without. The effect of cumulative fluid overload on treatment outcomes 2 days after surgery was analyzed. The risk factors for the development of AKI after surgery were assessed by logistic regression analysis. Compared with those without AKI after surgery, the patients with AKI had younger age, lower body weights, higher serum creatinine levels and higher vasoactive-inotropic score, as well as longer durations of intraoperative extracorporeal circulation and aortic occlusion (Pfluid overload 2 and 3 days after surgery (Pfluid overload and low cardiac output syndrome were major risk factors for the development of AKI after surgery. The children with cumulative fluid overload >5% at 2 days after surgery had a higher incidence rate of low cardiac output syndrome, a longer duration of mechanical ventilation, a longer length of stay in the ICU, a longer length of hospital stay, and a higher mortality rate (Pfluid overload after surgery for congenital heart disease tend to develop AKI, and fluid overload may be associated with poor outcomes after surgery.

    Retroviral insertion mutagenesis is considered a powerful tool to identify cancer genes in mice, but its significance for human cancer has remained elusive. Moreover, it has recently been debated whether common virus integrations are always a hallmark of tumor cells and contribute to the oncogenic process. Acute myeloid leukemia (AML) is a heterogeneous disease with a variable response to treatment. Recurrent cytogenetic defects and acquired mutations in regulatory genes are associated with AML subtypes and prognosis. Recently, gene expression profiling (GEP) has been applied to further risk stratify AML. Here, we show that mouse leukemia genes identified by retroviral insertion mutagenesis are more frequently differentially expressed in distinct subclasses of adult and pediatric AML than randomly selected genes or genes located more distantly from a virus integration site. The candidate proto-oncogenes showing discriminative expression in primary AML could be placed in regulatory networks mainly involved in signal transduction and transcriptional control. Our data support the validity of retroviral insertion mutagenesis in mice for human disease and indicate that combining these murine screens for potential proto-oncogenes with GEP in human AML may help to identify critical disease genes and novel pathogenetic networks in leukemia.

    In 2003, chronic obstructive pulmonary disease (COPD) accounted for 46% of the burden of chronic respiratory disease in the Australian community. In the 65-74-year-old age group, COPD was the sixth leading cause of disability for men and the seventh for women. To measure the influence of disease severity, COPD phenotype and comorbidities on acute health service utilization and direct acute care costs in patients admitted with COPD. Prospective cohort study of 80 patients admitted to the Royal Melbourne Hospital in 2001-2002 for an exacerbation of COPD. Patients were followed for 12 months and data were collected on acute care utilization. Direct hospital costs were derived using Transition II, an activity-based costing system. Individual patient costs were then modelled to ascertain which patient factors influenced total direct hospital costs. Direct costs were calculated for 225 episodes of care, the median cost per admission was AU$3124 (interquartile range $1393 to $5045). The median direct cost of acute care management per patient per year was AU$7273 (interquartile range $3957 to $14 448). In a multivariate analysis using linear regression modelling, factors predictive of higher annual costs were increasing age (P= 0.041), use of domiciliary oxygen (P= 0.008) and the presence of chronic heart failure (P= 0.006). This model has identified a number of patient factors that predict higher acute care costs and awareness of these can be used for service planning to meet the needs of patients admitted with COPD.

    Objective: To detect the minimal residual diseases (MRD) in acute promyelocytic leukemia (APL) after complete remission (CR) and to analyze its clinical value in prognosis. Methods: Reverse transcription Polymerase chain reaction (RT/PCR) was used to detect MRD of patients with APL. Results: MRD positive rate in patients with APL was 92.8% (39/42) before treatment and 56.7 (21/37) immediately after the ATRA or chemotherapy- induced CR. Furthermore, MRD positive rate wasrelated to the relapse in APL patients and could be considered as a marker to predict the relapse of patients with APL after CR. The MRD detection could also be applied to direct the consolidation therapy to prevent relapses. Conclusion: RT-PCR is valuable to monitor MRD and can be used as a marker to predict relapses.

    We report the case of a patient with acute exacerbation of chronic pancreatitis and he suffered an atraumatic splenic rupture. Splenic rupture not associated with trauma is a rare entity that can occurs in normal spleen (spontaneous) or damaged spleen (pathological). This entity may be associated with local inflammatory processes, such as pancreatitis. Ultrasound is a non-invasive technique which is used in unstable patients. CT is useful for making a diagnosis of extension in patients with hemodynamic stability. Atraumatic splenic rupture as a complication of chronic pancreatitis is an unusual disease that requires a high index of suspicion which allows us an early diagnosis because it is a treatable entity that compromises the patient's life.

    The collected works οf Hippocrates include a wealth of references to emergencies and acute conditions; if the physician could treat these, he would be considered superior to his colleagues. Works most relevant to current Emergency Medicine are presented. They indicate Hippocrates' remarkable insight and attention to the value of close observation, meticulous clinical examination, and prognosis. Hippocrates and his followers disdained mystery and were not satisfied until they had discovered a rational cause to diseases. They assigned great significance to distressing signs and symptoms - the famous Hippocratic face, the breathing pattern, pain, seizures, opisthotonus - pointing to a fatal outcome, which they reported to their patient. The principles of treatment of emergencies, such as angina, haemorrhage, empyema, ileus, shoulder dislocations and head injuries, are astonishingly similar to the ones used nowadays.

    Adult onset Still's disease (AOSD) is a systemic inflammatory disorder characterized by rash, leukocytosis, fever and arthralgia/arthritis. The most common pulmonary manifestations associated with AOSD are pulmonary infiltrates and pleural effusion. The present study describes a 40-year-old male with AOSD who developed fever, sore throat and shortness of breath. Difficulty breathing promptly developed, and the patient was diagnosed with acute respiratory distress syndrome (ARDS). The patient did not respond to antibiotics, including imipenem, vancomycin, fluconazole, moxifloxacin, penicillin, doxycycline and meropenem, but was sensitive to glucocorticoid treatment, including methylprednisolone sodium succinate. ARDS accompanied by AOSD has been rarely reported in the literature. In conclusion, in a patient with ARDS who does not respond to antibiotic treatment, the involvement of AOSD should be considered.

    Renal replacement therapy in acute renal failure (ARF) and chronic renal failure (end-stage renal disease; ESRD) has been based on the use of modifications of dialysis (continuous arteriovenous hemofiltration and hemodiafiltration) to remove middle-molecular-weight toxins, consisting of low-molecular-weight proteins and peptides (LMWP) and cytokines involved in inflammation. High-flux dialyzers are not efficient at removing LMWP, and for this reason, sorbents have been studied to augment or replace dialysis. Removal of LMWP such as beta2-microglobulin, leptin, complement factor D, angiogenin and cytokines such as interleukin (IL)-1, IL-6, IL-10, IL-18 and tumor necrosis factor-alpha has been established in animal models of sepsis and in ESRD patients using sorbents. Sorbent devices added to hemodialysis, or the use of such devices alone in inflammatory states, including sepsis, ARF, cardiopulmonary bypass, pre-explantation of donor organs and ESRD, are being studied.

    Orthotopic liver transplantation (OLT) for acute liver failure (ALF) during pregnancy is an uncommon occurrence with variable outcomes. In pregnancy-related liver failure, prompt diagnosis and immediate delivery are essential for a reversal of the underlying process and for maternal and fetal survival. In rare cases, the reason for ALF during pregnancy is either unknown or irreversible, and thus OLT may be necessary. This case demonstrates the development of cryptogenic ALF during the 26th week of pregnancy in a woman with sickle cell disease. She underwent successful cesarean delivery of a healthy male fetus at 27 weeks with concurrent OLT. This report provides a literature review of OLT in pregnancy and examines the common causes of ALF in the pregnant patient. On the basis of the management and outcome of our case and the literature review, we present an algorithm for the suggested management of ALF in pregnancy.

    The Notch signaling pathway is a highly conserved cell signaling system that plays an essential role in many biological processes. Notch signaling regulates multiple aspects of hematopoiesis, especially during T cell develop-ment. Recent data suggest that Notch also regulates mature T cell differentiation and function. The latest data show that Notch also plays an essential role in alloreactive T cells mediating acute graft-versus-host disease (aGVHD), the most severe complication of allogeneic hematopoietic stem cell transplantation (allo-HSCT). Notch inhibition in donor-derived T cells or blockade of individual Notch ligands and receptors after transplantation can reduce GVHD severity and mortality in mouse models of allo-HSCT, without causing global immunosuppression. These findings indicate Notch in T cells as an attractive therapeutic target to control aGVHD. In this article, the pathophysiology of aGVHD, the Notch signal pathway and aGVHD are reviewed.

    Full Text Available Myocardial infarction (MI is a complex disease that begins with a lifelong interaction between genetics and environmental factors. The aim of the study was to identify family history as a risk factor of myocardial infarction in examined population in the Municipality of Nis.We used a case-control study with 100 patients with a first MI (in the period 1998-2000 and 100 controls, matched with respect to sex and age (± 2 years from the Municipality of Nis.Data was obtained from the epidemiological questionnaire. The Yates c2 test, odds ratio-OR and their 99% interval of confident were used as statistical procedures.The results showed that statistical significance for MI was present among all three degrees of relatives of subjects who have had an acute MI, and for hypertension, hypercholesterolemia and stroke among first and second - degree relatives. The subjects with family history of hypercholesterolemia had 12.43 times higher risk of disease (p = 0,000 and in the case of family history of MI before the age of 55, the risk was almost 10 times (p = 0,000 higher. Almost 4 times higher risk of disease was registered in subjects with family history of hypertension (p < 0,00001 and stroke (before 65 years of age - (p < 00005; a two-fold higher risk was registered in subjects with diagnoses of diabetes (p < 0,05 and other cardiovascular diseases (unless hypertension (p < 0,01 in the nearest relatives before the age of 55.We concluded that family history of diseases on the sample of the Municipality of Nis inhabitants was very important risk factor, mostly in the first-degree relatives. Genetic epidemiology is the future for all investigations between different population, and special attention should be paid to investigations and findings of different genes and loci which are very important for myocardial infarction occurrence, which would allow a new approach to preventive medicine.

    BACKGROUND: Stroke is a common presentation in geriatric patients in emergency department but rarely seen in pediatric patients. In case of acute ischemic stroke in pediatric age group, management is different from that of adult ischemic stroke where thrombolysis is a good op. METHODS: We report a case of a 17-year-old male child presenting in emergency with an episode of acute ischemic stroke causing left hemiparesis with left facial weakness and asymmetry. The patient suffered from cyanotic congenital heart disease for which he had undergone Fontan operation previously. He had a history of missing his daily dose of warfarin for last 3 days prior to the stroke. RESULTS: The patient recovered from acute ischemic stroke without being thrombolyzed. CONCLUSION: In pediatric patients, acute ischemic stroke usually is evolving and may not require thrombolysis. PMID:25215056

    The purpose of the investigation was to assess the clinical significance of ultrasonography for differential diagnostics between acute inflammatory and tumorous lesions of the neck. One hundred and eighty-six patients with soft-tissue lesions of the neck aged 18 to 74 (mean age 31.45 +/- 8.39 years), 95 (51%) males and 91 (49%) females were examined. Basing on clinical and ultrasonographic examination, the patients were divided into two groups: 149 or 80% patients with acute inflammatory lesions (Group 1), and 37 or 20% patients with tumorous lesions (Group 2). Thirty-four of the 149 Group 1 patients (22.82%) had lymphadenitis, 30 (20.13%) had soft tissue infiltrates, 13 (8.72%) had abscesses, 19 (12.72%) had phlegmons, 32 (21.48%) had acute inflammatory changes in the major salivary glands, 3 (2.01%) had teratomas with signs of inflammation, and 17 (11.41%) patients had inflammatory changes in the tumors. Of 37 patients with tumorous lesions, 16 (43.2%) had salivary gland tumors, 12 (32.4%) had metastases in the lymphatic nodes, and 9 (24.3%) had neurofibromatosis. Soft tissue ultrasonography was performed using Sonos-5500 and Image-Point ultrasound scanners with 7.5 MHz sensors (Hewlett-Packard, USA), Logio-pro, Uoluson-730 Expert (General Electric, USA), and Premium Edition (ACUSON Antares, Siemens, Germany) with 5 to 13 MHz wide-frequency sensors. Visualization was performed in B-modes using tissue harmonics, color duplex scanning, Sie Scape panoramic visualization, contrast visualization and Sight 4D and 3D-Scape modes. The results of ultrasonography were analyzed taking into account additional methods such as computed and magnetic resonance tomography, intraoperative findings, the results of puncture biopsy, histological, morphological, and bacteriological studies. The study demonstrates that ultrasonography is the method of choice, which is in some cases enough to establish a diagnosis of an acute inflammatory disease or a tumorous formation of various

    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.

    Full Text Available Abstract Background Ambulance usage in Japan has increased consistently because it is free under the national health insurance system. The introduction of refusal for ambulance transfer is being debated nationally. The purpose of the present study was to investigate the relationship between prehospital data and hospitalization outcome for acute disease patients, and to develop a simple prehospital evaluation tool using prehospital data for Japan's emergency medical service system. Methods The subjects were 9,160 consecutive acute disease patients aged ≥ 15 years who were transferred to hospital by Kishiwada City Fire Department ambulance between July 2004 and March 2006. The relationship between prehospital data (age, systolic blood pressure, pulse rate, respiration rate, level of consciousness, SpO2 level and ability to walk and outcome (hospitalization or non-hospitalization was analyzed using logistic regression models. The prehospital score component of each item of prehospital data was determined by beta coefficients. Eligible patients were scored retrospectively and the distribution of outcome was examined. For patients transported to the two main hospitals, outcome after hospitalization was also confirmed. Results A total of 8,330 (91% patients were retrospectively evaluated using a prehospital score with a maximum value of 14. The percentage of patients requiring hospitalization rose from 9% with score = 0 to 100% with score = 14. With a cut-off point score ≥ 2, the sensitivity, specificity, positive predictive value and negative predictive value were 97%, 16%, 39% and 89%, respectively. Among the 6,498 patients transported to the two main hospitals, there were no deaths at scores ≤ 1 and the proportion of non-hospitalization was over 90%. The proportion of deaths increased rapidly at scores ≥ 11. Conclusion The prehospital score could be a useful tool for deciding the refusal of ambulance transfer in Japan's emergency medical

    Patients with acute graft versus host disease (GvHD) grade I, were randomized, to an observation arm (n=85) or to a treatment arm (n=86), consisting of 6-methylprednisolone 1 mg/kg/day , after stratification for age and donor type. The primary end point was development of grade II-IV GvHD. The cumulative incidence of GvHD grade II-IV, was 50% in the observation and 33% in the treatment arm (p=0.005). However, grade III-IV GvHD was comparable (13% vs 10% respectively; p=0.6), and this was true for sibling and alternative donor transplants. Moderate/severe chronic GvHD was also comparable (17% vs 19%). In multivariate analysis, an early interval between transplant and randomization (< day +20) , was the only negative predictor of GvHD grade III-IV .Patients in the observation arm had less infectious bacterial episodes (12 vs 25, p=0.04), less severe infectious fungal episodes (0 vs 3; p=0.04), and less severe adverse events (3 vs 11 p=0.07). At 5 years, non relapse mortality was 20% (observation) vs 26% (treatment) (p=0.2), relapse related death 25% vs 21%, and actuarial survival was 51% vs 41% respectively (p=0.3). In multivariate analysis, advanced disease phase, older age and an early onset of GvHD, were significant negative predictors of survival, independent of the randomization arm. In conclusion, steroids treatment of acute GvHD grade I prevents progression to grade II but not to grade III-IV GvHD, and there is no effect on non relapse mortality and survival; patients treated with steroids, are at a higher risk of develping infections and have more adverse events.

    Lyme disease is a tick-borne illness caused by the bacterium Borrelia burgdorferi, and approximately 10 to 20% of patients report persistent symptoms lasting months to years despite appropriate treatment with antibiotics. To gain insights into the molecular basis of acute Lyme disease and the ensuing development of post-treatment symptoms, we conducted a longitudinal transcriptome study of 29 Lyme disease patients (and 13 matched controls) enrolled at the time of diagnosis and followed for up to 6 months. The differential gene expression signature of Lyme disease following the acute phase of infection persisted for at least 3 weeks and had fewer than 44% differentially expressed genes (DEGs) in common with other infectious or noninfectious syndromes. Early Lyme disease prior to antibiotic therapy was characterized by marked upregulation of Toll-like receptor signaling but lack of activation of the inflammatory T-cell apoptotic and B-cell developmental pathways seen in other acute infectious syndromes. Six months after completion of therapy, Lyme disease patients were found to have 31 to 60% of their pathways in common with three different immune-mediated chronic diseases. No differential gene expression signature was observed between Lyme disease patients with resolved illness to those with persistent symptoms at 6 months post-treatment. The identification of a sustained differential gene expression signature in Lyme disease suggests that a panel of selected human host-based biomarkers may address the need for sensitive clinical diagnostics during the "window period" of infection prior to the appearance of a detectable antibody response and may also inform the development of new therapeutic targets. Lyme disease is the most common tick-borne infection in the United States, and some patients report lingering symptoms lasting months to years despite antibiotic treatment. To better understand the role of the human host response in acute Lyme disease and the

    Full Text Available Introduction: Peptic ulcer disease (PUD has been recognized as the leading cause of acute upper gastrointestinal bleeding (AUGIB. This study aims to report general features of bleeding peptic ulcers in patients who benefit of urgent endoscopy in our department after an acute upper gastrointestinal hemorrhage. Results: A total of 1809 patients were explored for acute upper gastrointestinal bleeding in our unit since 2003 to 2008. Gastroduodenal peptic ulcers were the most frequent diagnosed etiology. They present 38% of all reported causes of bleeding (n=527 (table I. 25% were located at duodenal mucosa (n= 347 and 13% were gastric ulcers (n=180. No esophageal ulcers were reported. Incidence of both duodenal and gastric ulcers decreases during the last years. Conclusion: In our department, incidence of bleeding peptic ulcer disease is decreasing but they continue to be the first cause of AUGIB.

    Discontinuation of acute, unplanned dialysis is always an important therapeutic goal in dialysis-requiring patients with existing chronic kidney disease. Only a limited proportion of patients could be weaned off dialysis and remained dialysis-free. Here we performed a multicenter, observational study to investigate factors associated with successful weaning from acute dialysis, and to explore the potential impact of weaning itself on outcomes of patients with chronic kidney disease following urgent-start dialysis. We recruited 440 chronic kidney disease patients with a baseline estimated glomerular filtration rate 1 month died, and 36 (8.6%) were removed from dialysis, with 26 (6.2%) remaining alive and dialysis-free. Logistic regression analysis found that age ≧ 65 years, ischemic acute tubular necrosis, nephrotoxic exposure, urinary obstruction, and higher predialysis estimated glomerular filtration rate and serum hemoglobin were predictors of weaning off dialysis. After adjustment for propensity scores for dialysis weaning, Cox proportional hazards models showed successful weaning from dialysis (adjusted hazard ratio 0.06; 95% confidence interval 0.01 to 0.35), along with a history of hypertension and serum albumin, were independent protectors for early death. Conversely, a history of stroke, peripheral arterial disease and cancer predicted the occurrence of early mortality. In conclusion, this prospective cohort study shows that compared to patients with chronic kidney disease who became end-stage renal disease after acute dialysis, patients who could be weaned off acute dialytic therapy were associated with reduced risk of premature death over a 2-year observation period.

    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.

    Purpose: To investigate the safety and efficacy of emergency treatment of acute aortic diseases with endovascular stent grafts. Methods: In 11 patients (median age 55 years, range 18 - 85) with acute complications of descending aortic diseases endovascular emergency treatment was performed: traumatic aortic rupture (n = 4), penetrating ulcer with aortobronchial fistula or hematothorax (n = 4), acute type B dissection (n = 2, one with penetration, one with subacute mesenteric ischemia), and symptomatic aneurysm of the thoracic aorta (n = 1) with pain and diameter progression. 15 stent grafts were implanted (Talent n = 11, Vanguard/Stentor n = 4). Stent extension was necessary in 4 cases. In 2 cases graft extension was done during the first procedure (due to distal migration and due to the total length of the aortic aneurysm). In 2 cases graft extension was performed 5 days (due to a new aortic ulcer at the proximal stent struts) and 5 months after the initial procedure (recurrent aortobronchial fistula due to aneurysm progression). 14 of 15 implantations required general anesthesia, one symptomatic thoracic aneurysm was performed in local anesthesia and sedation. Results: 14 of 15 graft procedures were performed using the femoral or iliac approach. One procedure required aortofemoral bypass grafting due to extensive arteriosclerotic stenosis and the stent graft was inserted via the bypass graft. The orifice of the subclavian artery was crossed with bare stent struts in 4 cases without neurological complications. Median follow-up is 27 months (range 6 to 72 months). In traumatic aortic ruptures, immediate sealing of bleeding was achieved and follow-up is inconspicuous at a maximum of 72 months. In cases of aortobronchial fistulas, follow-up is satisfactory (maximum 72 months) despite the necessity for reintervention and graft extension. In one acute type B dissection retrograde dissection of the aortic arch occurred during stent release with stable disease during

    Objective HIV-infected patients in Africa are vulnerable to severe recurrent infection with Streptococcus pneumoniae, but no effective preventive strategy has been developed. We set out to determine which factors influence in-hospital mortality and long-term survival of Malawians with invasive pneumococcal disease. Design, setting and patients Acute clinical features, inpatient mortality and long-term survival were described among consecutively admitted hospital patients with S. pneumoniae in the blood or cerebrospinal fluid. Factors associated with inpatient mortality were determined, and patients surviving to discharge were followed to determine their long-term outcome. Results A total of 217 patients with pneumococcal disease were studied over an 18-month period. Among these, 158 out of 167 consenting to testing (95%) were HIV positive. Inpatient mortality was 65% for pneumococcal meningitis (n = 64), 20% for pneumococcaemic pneumonia (n = 92), 26% for patients with pneumococcaemia without localizing signs (n = 43), and 76% in patients with probable meningitis (n = 17). Lowered consciousness level, hypotension, and age exceeding 55 years at presentation were associated with inpatient death, but not long-term outcome in survivors. Hospital survivors were followed for a median of 414 days; 39% died in the community during the study period. Outpatient death was associated with multilobar chest signs, oral candidiasis, and severe anaemia as an inpatient. Conclusion Most patients with pneumococcal disease in Malawi have HIV co-infection. They have severe disease with a high mortality rate. At discharge, all HIV-infected adults have a poor prognosis but patients with multilobar chest signs or anaemia are at particular risk.

    Chronic bronchitis and chronic obstructive pulmonary disease (COPD) are serious conditions in which patients are predisposed to viral and bacterial infections resulting in potentially fatal acute exacerbations. Chronic obstructive pulmonary disease is defined as a lung disease characterised by obstruction to lung airflow that interferes with normal breathing. Antibiotic therapy has not been particularly useful in eradicating bacteria such as non-typeable Haemophilus influenzae (NTHi) because they are naturally occurring flora of the upper respiratory tract in many people. However, they can cause opportunistic infection. An oral NTHi vaccine has been developed to protect against recurrent infective acute exacerbations in chronic bronchitis. To assess the effectiveness of an oral, whole-cell NTHi vaccine in protecting against recurrent episodes of acute exacerbations of chronic bronchitis and COPD in adults. To assess the effectiveness of NTHi vaccine in reducing NTHi colonising the respiratory tract during recurrent episodes of acute exacerbations of COPD. We searched the following databases: the Cochrane Central Register of Controlled Trials (CENTRAL) (2017, Issue 1), MEDLINE (1946 to January 2017), Embase (1974 to January 2017), CINAHL (1981 to January 2017), LILACS (1985 to January 2017), and Web of Science (1955 to January 2017). We also searched trials registries and contacted authors of trials requesting unpublished data. We included randomised controlled trials comparing the effects of an oral monobacterial NTHi vaccine in adults with recurrent acute exacerbations of chronic bronchitis or COPD when there was overt matching of the vaccine and placebo groups on clinical grounds. The selection criteria considered populations aged less than 65 years and those older than 65 years. Two review authors independently assessed trial quality and extracted data from original records and publications for incidence and severity of bronchitis episodes and carriage rate of

    Objective: To investigate children with acute non-communicable diseases (NCDs) and their caregivers in developing countries. Methods: A cross-sectional survey was conducted in three out of the ten regions of Ghana. A total of 1 540 caregivers/parents of children with NCDs were interviewed. Data was analysed with the aid of IBM SPSS version 20. Statistical techniques used in the analysis included frequencies, means, SD and factor analysis. Findings were analysed according to the major themes of the study. Results: Caregivers indicated that the incidence of NCDs among children is on the in-crease. They also believed that enemies can cause diseases in children. Caregivers tend to seek treatment in hospitals/clinics rather than from traditional or herbal medicine. However, they complement biomedical treatment with prayers for healing/deliverance. It was also found that NCDs have a negative effect on the physical and mental development of children as well as their school performance;and caring for children with NCDs also poses material, emotional and financial burden to caregivers. Conclusions: Serious attention needs to be given to the development and implementa-tion of policies to better the lot of children with NCDs. Conscious efforts need to be made to encourage and assist the caregivers with necessary resources to cater for their children's educational and health needs in particular.

  8. Acute Inflammatory Bowel Disease Complicating Chronic Alcoholism and Mimicking Carcinoid Syndrome

    Full Text Available We report the case of a woman with a history of chronic alcohol abuse who was hospitalized with diarrhea, severe hypokalemia refractory to potassium infusion, nausea, vomiting, abdominal pain, alternations of high blood pressure with phases of hypotension, irritability and increased urinary 5-hydroxyindoleacetic acid and cortisol. Although carcinoid syndrome was hypothesized, abdominal computed tomography and colonoscopy showed non-specific inflammatory bowel disease with severe colic wall thickening, and multiple colic biopsies confirmed non-specific inflammation with no evidence of carcinoid cells. During the following days diarrhea slowly decreased and the patient’s condition progressively improved. One year after stopping alcohol consumption, the patient was asymptomatic and serum potassium was normal. Chronic alcohol exposure is known to have several deleterious effects on the intestinal mucosa and can favor and sustain local inflammation. Chronic alcohol intake may also be associated with high blood pressure, behavior disorders, abnormalities in blood pressure regulation with episodes of hypotension during hospitalization due to impaired baroreflex sensitivity in the context of an alcohol withdrawal syndrome, increased urinary 5-hydroxyindoleacetic acid as a result of malabsorption syndrome, and increased urinary cortisol as a result of hypothalamic-pituitary-adrenal axis dysregulation. These considerations, together with the regression of symptoms and normalization of potassium levels after stopping alcohol consumption, suggest the intriguing possibility of a alcohol-related acute inflammatory bowel disease mimicking carcinoid syndrome.

    Epidural hematoma (EDH) in newborn infants is rare compared with other types of intracranial hemorrhages. Furthermore, posterior fossa EDH is extremely rare. We present a case of posterior fossa EDH in an infant with Menkes disease with accessory bones in the occiput. A male infant with a condition diagnosed with Menkes disease by prenatal testing was born at 39 weeks via vacuum extraction. The patient presented with a mild tremor at 2 days after delivery. A brain computed tomography (CT) scan showed an acute EDH in the posterior fossa, extending into the occipitoparietal area. Three-dimensional CT and bone window CT scan revealed several accessory bones, diastasis of 1 accessory suture, a communicated fracture, and a linear fracture in the occipital bone. Furthermore, a bone fragment from a communicated fracture displaced toward the inside. The patient was treated conservatively for EDH because of his good general condition. The hematoma gradually resolved, and his tremor did not recur. We suggest the following mechanism of posterior fossa EDH development in our patient: (1) external force was applied to the occiput inside the birth canal during delivery, resulting in diastasis; (2) a communicated fracture occurred, and a bone fragment displaced toward the inside (linear fracture was caused indirectly by the force); (3) a transverse sinus was injured by the fragment; and (4) EDH developed in both the posterior fossa and supratentorial region. Copper deficiency can also cause fragility of connective tissues, vessels, and bones.

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

    Directory of Open Access Journals (Sweden)

    Rafael Coimbra Ferreira Beltrame

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

    The indium 111 granulocyte scan was used to evaluate 39 individuals known to have or suspected of having inflammatory bowel disease. Twenty-three of these individuals had positive scans and 16 had negative scans. Eighty-seven confirmatory studies, which consisted of barium radiography, endoscopy, operative findings, and histopathology, were performed in 37 of these individuals. The remaining two negative scans corroborated only by clinical course, CBC, and erythrocyte sedimentation rate. In addition, 10 follow-up scans were performed in six of the 39 patients to monitor therapy or investigate a change in symptoms. As an anatomic indicator of acute granulocytic infiltration of the intestinal lamina propria and crypts, the authors found that this scan had a 97 percent rate of sensitivity and 100 percent specificity. Specific indications for the use of the indium 111-labeled granulocyte scan are described. For the authors, in general, this test has become a vital adjunct to endoscopy and radiography in the diagnosis and management of patients with symptoms of inflammatory bowel disease.

    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.

    The study objective was to ascertain the incidence of bleeding and ischemic complications related to acute and planned orthopedic surgery in patients with known cardiovascular diseases. The study conducted between 2010 and 2013 enrolled 477 patients (289 women, 188 men) with a diagnosed cardiovascular disease or a history of thromboembolic event. Aside from gender, age, height and weight, the study observed other anamnestic data and perioperative laboratory test results that may impact on a bleeding or ischemic event. Two hundred seventy-two (57 %) patients had acute surgery, and 205 (43 %) patients had elective surgery. Complications arose in 55 (11.6 %) patients, 32 (6.9 %) had bleeding complications, 19 (4.0 %) ischemic complications, and both complications were experienced by 4 (0.8 %) patients. Bleeding developed in 14 (5.1 %) patients who had acute surgery, and in 22 (10.7 %) who had elective surgery. Twenty-two (8.1 %) patients having acute surgery and one (0.1 %) undergoing elective surgery suffered from ischemic complications. The incidence of bleeding complications was significantly higher in elective surgery (p = 0.026, OR 2.22), and when adjusted (general anaesthesia, gender, and use of warfarin), the difference was even higher (p = 0.015, OR 2.44), whereas the occurrence of ischemic complications was significantly higher in acute surgery (p = 0.005, OR 18.0), and when adjusted (age), the difference remained significant (p = 0.044, OR 8.3). The study noted a significantly higher incidence of bleeding complications in elective orthopedic surgery when compared with acute surgery. Conversely, the incidence of ischemic complications was significantly higher in patients having acute orthopedic surgery when compared with those operated on electively.

    Increased cardiac troponin concentrations in acute coronary syndrome (ACS) identify patients with ongoing cardiomyocyte necrosis who are at increased risk. However, with the use of more precise assays, cardiac troponin increases are commonly noted in other cardiovascular conditions as well. This has generated interest in the use of cardiac troponin for prognostic assessment and clinical management of these patients. In this review, we have summarized the data from studies investigating the implications of cardiac troponin concentrations in various acute and chronic conditions beyond ACS, i.e., heart failure, myocarditis, Takotsubo cardiomyopathy, aortic dissection, supraventricular arrhythmias, valve disease, pulmonary arterial hypertension, stroke, and in the perioperative setting. Cardiac troponin concentrations are often detectable and frankly increased in non-ACS conditions, in particular when measured with high-sensitivity (hs) assays. With the exception of myocarditis and Takotsubo cardiomyopathy, cardiac troponin concentrations carry strong prognostic information, mainly with respect to mortality, or incipient and/or worsening heart failure. Studies investigating the prognostic benefit associated with cardiac troponin-guided treatments however, are almost lacking and the potential role of cardiac troponin in the management of non-ACS conditions is not defined. Increased cardiac troponin indicates increased risk for adverse outcome in patients with various cardiovascular conditions beyond ACS. Routine measurement of cardiac troponin concentrations can however, not be generally recommended unless there is a suspicion of ACS. Nonetheless, any finding of an increased cardiac troponin concentration in a patient without ACS should at least prompt the search for possible underlying conditions and these should be managed meticulously according to current guidelines to improve outcome. © 2016 American Association for Clinical Chemistry.

    Full Text Available In spite of commonly spread positive opinion about the antibacterial and antiviral properties of garlic, very few and fragmented data exist on the benefits of garlic and garlic-based preparations in the prevention of acute respiratory diseases (ARD. This study was performed to elucidate the effect of timereleased garlic powder tablets (Allicor in prevention of ARD in children. At the first stage, in open-labeled 5-months study it has been shown that ARD morbidity was reduced by 2.4-fold in 172 Allicor-treated (600 mg daily schoolchildren aged 7-16 as compared to 468 controls. At the second stage, the effects of Allicor (300 mg daily on ARD morbidity were investigated in the double-blinded placebo-controlled randomized 5-months comparative study in 42 children aged 10-12 in comparison with 41 placebo-treated children and 73 benzimidazole-treated children. Allicor treatment reduced ARD morbidity by 2.4-fold as compared to placebo, and by 1.7-fold as compared to benzimidazole. Health index in Allicor-treated group was 1.5-fold higher as compared either to placebo- or benzimidazole-treated children. The results of this study have demonstrated that garlic powder tablets Allicor are effective in non-specific prevention of acute respiratory infections in children and possess no side effects. Additionally, the commonly used ARD prevention withbenzimidazole turned to be entirely ineffective in placebocontrolled study, so the development of new useful and safe efficient drugs like garlic-based preparations is of ultimate importance.

    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.

    To test accuracy and reproducibility of gestalt to predict obstructive coronary artery disease (CAD) in patients with acute chest pain. We studied individuals who were consecutively admitted to our Chest Pain Unit. At admission, investigators performed a standardized interview and recorded 14 chest pain features. Based on these features, a cardiologist who was blind to other clinical characteristics made unstructured judgment of CAD probability, both numerically and categorically. As the reference standard for testing the accuracy of gestalt, angiography was required to rule-in CAD, while either angiography or non-invasive test could be used to rule-out. In order to assess reproducibility, a second cardiologist did the same procedure. In a sample of 330 patients, the prevalence of obstructive CAD was 48%. Gestalt's numerical probability was associated with CAD, but the area under the curve of 0.61 (95%CI: 0.55-0.67) indicated low level of accuracy. Accordingly, categorical definition of typical chest pain had a sensitivity of 48% (95%CI: 40%-55%) and specificity of 66% (95%CI: 59%-73%), yielding a negligible positive likelihood ratio of 1.4 (95%CI: 0.65-2.0) and negative likelihood ratio of 0.79 (95%CI: 0.62-1.02). Agreement between the two cardiologists was poor in the numerical classification (95% limits of agreement = -71% to 51%) and categorical definition of typical pain (Kappa = 0.29; 95%CI: 0.21-0.37). Clinical judgment based on a combination of chest pain features is neither accurate nor reproducible in predicting obstructive CAD in the acute setting.

  6. Vitamin D deficiency aggravates chronic kidney disease progression after ischemic acute kidney injury.

    Directory of Open Access Journals (Sweden)

    Janaína Garcia Gonçalves

    Full Text Available Despite a significant improvement in the management of chronic kidney disease (CKD, its incidence and prevalence has been increasing over the years. Progressive renal fibrosis is present in CKD and involves the participation of several cytokines, including Transforming growth factor-β1 (TGF-β1. Besides cardiovascular diseases and infections, several studies show that Vitamin D status has been considered as a non-traditional risk factor for the progression of CKD. Given the importance of vitamin D in the maintenance of essential physiological functions, we studied the events involved in the chronic kidney disease progression in rats submitted to ischemia/reperfusion injury under vitamin D deficiency (VDD.Rats were randomized into four groups: Control; VDD; ischemia/reperfusion injury (IRI; and VDD+IRI. At the 62 day after sham or IRI surgery, we measured inulin clearance, biochemical variables and hemodynamic parameters. In kidney tissue, we performed immunoblotting to quantify expression of Klotho, TGF-β, and vitamin D receptor (VDR; gene expression to evaluate renin, angiotensinogen, and angiotensin-converting enzyme; and immunohistochemical staining for ED1 (macrophages, type IV collagen, fibronectin, vimentin, and α-smooth mucle actin. Histomorphometric studies were performed to evaluate fractional interstitial area.IRI animals presented renal hypertrophy, increased levels of mean blood pressure and plasma PTH. Furthermore, expansion of the interstitial area, increased infiltration of ED1 cells, increased expression of collagen IV, fibronectin, vimentin and α-actin, and reduced expression of Klotho protein were observed. VDD deficiency contributed to increased levels of plasma PTH as well as for important chronic tubulointerstitial changes (fibrosis, inflammatory infiltration, tubular dilation and atrophy, increased expression of TGF-β1 and decreased expression of VDR and Klotho protein observed in VDD+IRI animals.Through inflammatory

    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

  8. Oxidative stress and Kawasaki disease: how is oxidative stress involved from the acute stage to the chronic stage?

    2017-01-01

    Inflammation and oxidative stress are closely related. Further, oxidative stress plays an important role in the pathology of inflammation-based Kawasaki disease. An excessive in vivo production of reactive oxygen species increases oxidative stress in the body, which triggers an endless vicious spiral of inflammation reactions and reactive oxygen metabolites. This presumably forms diffuse vasculitis in the acute phase. Acute inflammation and oxidative stress can be rapidly controlled by treatments; however, they may remain for a long time. This has recently been identified as a problem in the chronic phase of Kawasaki disease. Generally, the presence of vascular inflammation and oxidative stress impairs blood vessels, leading to the onset of atherosclerosis, which is a widely recognized risk. The current discussion focuses on whether the same is valid for blood vessels in the chronic phase of Kawasaki disease.

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

    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.

    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.

    Vestibular migraine is the most common cause of acute episodic vestibular symptoms after benign paroxysmal positional vertigo. In contrast, Ménière's disease is an uncommon disorder. For both conditions, early and accurate diagnosis (or its exclusion) enables the correct management of patients with acute episodic vestibular symptoms. Long-term management of migraine requires changes in lifestyle to avoid triggers of migraine and/or prophylactic drugs if attacks become too frequent. The long-term management of Ménière's disease also involves lifestyle changes (low salt diet), medications (betahistine, steroids), and ablative therapy applied to the diseased ear (eg, intratympanic gentamicin).

    Our aim was to improve outcome prediction after allogeneic hematopoietic stem cell transplantation in acute myeloid leukemia by combining cytogenetic and molecular data at diagnosis with minimal residual disease assessment by multicolor flow-cytometry at transplantation. Patients with acute myeloid leukemia in first complete remission in whom minimal residual disease was assessed at transplantation were included and categorized according to the European LeukemiaNet classification. The primary outcome was 1-year relapse incidence after transplantation. Of 152 patients eligible, 48 had minimal residual disease at the time of their transplant. Minimal residual disease-positive patients were older, required more therapy to achieve first remission, were more likely to have incomplete recovery of blood counts and had more adverse risk features by cytogenetics. Relapse incidence at 1 year was higher in patients with minimal residual disease (32.6% versus 14.4%, P=0.002). Leukemia-free survival (43.6% versus 64%, P=0.007) and overall survival (48.8% versus 66.9%, P=0.008) rates were also inferior in patients with minimal residual disease. In multivariable analysis, minimal residual disease status at transplantation independently predicted 1-year relapse incidence, identifying a subgroup of intermediate-risk patients, according to the European LeukemiaNet classification, with a particularly poor outcome. Assessment of minimal residual disease at transplantation in combination with cytogenetic and molecular findings provides powerful independent prognostic information in acute myeloid leukemia, lending support to the incorporation of minimal residual disease detection to refine risk stratification and develop a more individualized approach during hematopoietic stem cell transplantation.

    Heitor Pons Leite

    Full Text Available OBJECTIVE: To report on acquired experience of metabolic support for children with acute neurological diseases, emphasizing enteral tube feeding usage and metabolic assessment, and also to recommend policies aimed towards improving its implementation. DESIGN: Retrospective analysis. SETTING: Pediatric Intensive Care Unit of Hospital do Servidor Público Estadual de São Paulo. SUBJECTS: 44 patients consecutively admitted to the Pediatric ICU over a period of 3 years who were given nutrition and metabolic support for at least 72 hours. Head trauma, CNS infections and craniotomy post-operative period following tumor exeresis were the main diagnoses. MEASUREMENTS: Records of protein-energy intake, nutrient supply route, nitrogen balance and length of therapy. RESULTS: From a total of 527 days of therapy, single parenteral nutrition was utilized for 34.3% and single enteral tube feeding for 79.1% of that period. 61.4% of the children were fed exclusively via enteral tube feeding, 9.1% via parenteral and 39.5 % by both routes. The enteral tube feeding was introduced upon admission and transpyloric placement was successful in 90% of the cases. Feeding was started 48 hours after ICU admission. The caloric goal was achieved on the 7th day after admission, and thereafter parenteral nutrition was interrupted. The maximum energy supply was 104.2 ± 23.15 kcal/kg. The median length of therapy was 11 days (range 4-38. None of the patients on tube feeding developed GI tract bleeding, pneumonia or bronchoaspiration episodes and, of the 4 patients who were given exclusive TPN, 2 developed peptic ulcer. The initial urinary urea nitrogen was 7.11 g/m2 and at discharge 6.44 g/m2. The protein supply increased from 1.49 g/kg to 3.65 g/kg (p< 0.01. The nitrogen balance increased from -7.05 to 2.2 g (p< 0.01. CONCLUSIONS: Children with acute neurological diseases are hypercatabolic and have high urinary nitrogen losses. The initial negative nitrogen balance can be

  18. Redrawing Papez' circuit: a theory about how acute stress becomes chronic and causes disease.

    Science.gov (United States)

    Eggers, Arnold E

    2007-01-01

    The diseases of chronic stress include migraine, essential hypertension, depression, and the metabolic syndrome. A theory is presented to explain how acute stress becomes chronic and causes these inter-related conditions. The theory is based on a new "circuit of emotion", which is derived from Papez' famous theory of emotion. The hypothesis is as follows: There is a basic circuit of emotion which runs from the hippocampus (defined as the dentate gyrus plus the CA regions), where emotion arises, to the amygdala and from there to serotonergic pacemaker cells in the dorsal raphe nucleus (DRN). The DRN projects back to the dentate gyrus in two ways: a direct route without a stop and an indirect route via pacemaker cells in the entorhinal cortex. The purpose of the direct route is to promote neurogenesis in the subgranular zone of the dentate; the indirect route has two purposes: to imprint ongoing moments of consciousness onto new dentate cells for retention as memory and to provide a negative feedback loop for regulation of the whole process. The hippocampus, the amygdala, and the DRN all project to the hypothalamus, which are branches off the basic loop that subserve the autonomic expression of emotion. Pathologic overdrive of the DRN causes overdrive of the entorhinal cortex, which leads to excitotoxic cell death of neurons in the hippocampus involved in the negative feedback loop. The disinhibited amygdala and DRN are then free to orchestrate the syndromes of chronic stress. Recovery from chronic stress requires repopulation of the dentate gyrus and restoration of the feedback loop. Excitotoxic cell death in the hippocampus results from either extraordinary acute stress or increased susceptibility to DRN overdrive, as might be caused, for example, by genetic factors, age, high cortisol levels, or incomplete recovery from previous damage. Three goals for therapeutic intervention are identified: inhibition of pacemaker cells in the DRN (which can be targeted by

    In March 2010 and January 2012, we documented 2 widespread and severe coral disease outbreaks on reefs throughout Kāne‘ohe Bay, Hawai‘i (USA). The disease, acute Montipora white syndrome (aMWS), manifested as acute and progressive tissue loss on the common reef coral M. capitata. Rapid visual surveys in 2010 revealed 338 aMWS-affected M. capitata colonies with a disease abundance of (mean ± SE) 0.02 ± 0.01 affected colonies per m of reef surveyed. In 2012, disease abundance was significantly higher (1232 aMWS-affected colonies) with 0.06 ± 0.02 affected colonies m-1. Prior surveys found few acute tissue loss lesions in M. capitata in Kāne‘ohe Bay; thus, the high number of infected colonies found during these outbreaks would classify this as an emerging disease. Disease abundance was highest in the semi-enclosed region of south Kāne‘ohe Bay, which has a history of nutrient and sediment impacts from terrestrial runoff and stream discharge. In 2010, tagged colonies showed an average tissue loss of 24% after 1 mo, and 92% of the colonies continued to lose tissue in the subsequent month but at a slower rate (chronic tissue loss). The host-specific nature of this disease (affecting only M. capitata) and the apparent spread of lesions between M. capitatacolonies in the field suggest a potential transmissible agent. The synchronous appearance of affected colonies on multiple reefs across Kāne‘ohe Bay suggests a common underlying factor. Both outbreaks occurred during the colder, rainy winter months, and thus it is likely that some parameter(s) associated with winter environmental conditions are linked to the emergence of disease outbreaks on these reefs.

    To investigate the acute effect of a t'ai chi chuan session on blood pressure and heart rate in patients with peripheral artery disease (PAD). Randomized crossover intervention study. Outpatient therapy center. Seven patients with PAD, aged 50-79 years, not using β-blockers, calcium-channel blockers, or nondihidropiridinic vasodilators. T'ai chi chuan and control session (both sessions lasted 40 minutes). Systolic and diastolic blood pressure and heart rate, which were evaluated before and after the intervention (10, 30, and 50 minutes). T'ai chi chuan exercise acutely decreased systolic blood pressure at 30 minutes after exercise (p = 0.042) and increased diastolic blood pressure at 50 minutes after exercise (p = 0.041). Heart rate did not change after t'ai chi chuan exercise. T'ai chi chuan acutely decreases systolic blood pressure in patients with PAD.

    Full Text Available Diarrhea is a condition where there is an increase in defecation of a person. The subject passes watery stools. Diarrhea affects many people in developed and developing countries. Millions of people die each year due to this disease. Keeping this in mind World Health Organization encourage studies on diarrhea which include research on traditional herbal medicine. Kutaja parpati vati is a licensed polyherbal formulation which are known to be anti diarrheal in nature. But no scientific report is available for its combined anti diarrheal potential. Hence, the present study is aimed to investigate the anti diarrheal activity of the licensed polyherbal formulation Kutaja parpati vati. In this study castor oil induced diarrhea and enteropooling models were used on male wistar rats. High and low doses of the polyherbal offered significant dose dependent protection in diarrheal conditions. It significantly reduced watery diarrhea and intestinal contents conditions. Standard drug used was loperamide. Hence we can conclude that Kutaja parpati vati possesses anti diarrheal properties and the drug look promising in the treatment of diarrhea.

    Full Text Available BACKGROUND: The new epidemiological scenario of orally transmitted Chagas disease that has emerged in Brazil, and mainly in the Amazon region, needs to be addressed with a new and systematic focus. Belém, the capital of Pará state, reports the highest number of acute Chagas disease (ACD cases associated with the consumption of açaí juice. METHODOLOGY/PRINCIPAL FINDINGS: The wild and domestic enzootic transmission cycles of Trypanosoma cruzi were evaluated in the two locations (Jurunas and Val-de Cães that report the majority of the autochthonous cases of ACD in Belém city. Moreover, we evaluated the enzootic cycle on the three islands that provide most of the açaí fruit that is consumed in these localities. We employed parasitological and serological tests throughout to evaluate infectivity competence and exposure to T. cruzi. In Val-de-Cães, no wild mammal presented positive parasitological tests, and 56% seroprevalence was observed, with low serological titers. Three of 14 triatomines were found to be infected (TcI. This unexpected epidemiological picture does not explain the high number of autochthonous ACD cases. In Jurunas, the cases of ACD could not be autochthonous because of the absence of any enzootic cycle of T. cruzi. In contrast, in the 3 island areas from which the açaí fruit originates, 66.7% of wild mammals and two dogs displayed positive hemocultures, and 15.6% of triatomines were found to be infected by T. cruzi. Genotyping by mini-exon gene and PCR-RFLP (1f8/Akw21I targeting revealed that the mammals and triatomines from the islands harbored TcI and Trypanosoma rangeli in single and mixed infections. CONCLUSION/SIGNIFICANCE: These findings show that cases of Chagas disease in the urban area of Belém may be derived from infected triatomines coming together with the açaí fruits from distant islands. We term this new epidemiological feature of Chagas disease as "Distantiae transmission".

    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 (PaO{sub 2}) (p=.003, r=-.53) and the alveolar-arterial oxygen tension difference (AaDO{sub 2}) (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)

  5. An Investigation of the Ability of the Glutaraldehyde Test to Distinguish between Acute and Chronic Inflammatory Disease in Horses

    Schumacher J

    2005-06-01

    Full Text Available The Glutaraldehyde test (GT, a rapid and inexpensive test, has been utilized empirically for many years in bovine practice for diagnosing inflammatory diseases. GT is used primarily to demonstrate increased serum concentrations of fibrinogen and globulin. Glutaraldehyde binds with free amino groups in fibrinogen and immunoglobulin to create a clot in a first degree chemical reaction. The clotting time of the GT estimates the content of proteins produced in response to inflammation. The applicability of GT for diagnosing inflammation in the horse has never been investigated. The objective of this study was to determine the ability of GT to distinguish between acute and chronic inflammatory disease in horses. Thirty-seven horses with suspected inflammatory diseases were evaluated using the GT, history, complete clinical examination and routine blood analysis. GT-times, laboratory results and clinical outcome were compared statistically. Horses that were determined to be acutely affected (based on history, clinical examination and routine blood analysis tended to have a negative GT (75%. Results of the GT did not correlate with blood fibrinogen concentration. Positive GT also predicted a fatal outcome in 69% of the clinical cases. The results of this trial indicate that GT can be a useful screening test to distinguish between acute and chronic inflammatory disease in horses.

    A cytopathogenic virus was isolated in the primary culture of bovine kidney cells from a nasal swab of affected calves in an outbreak of acute respiratory disease in Japan in 1971. It agglutinated human type O erythrocytes and produced cytoplasmic inclusion bodies. Viral replication was inhibited by 5-iodo-2'-deoxyuridine, indicating that the viral nucleic acid was RNA. The virus was resistant to ether, chloroform, sodium deoxycholate, and acid, and passed readily through Sartorius' membrane filter 100 nm in pore size, but not through the filter 50 nm in pore size. Electron microscopy showed many spherical particles 60 approximately 75 nm in diameter with a double-layered capsid in a sample taken at a buoyant density of 1.34 produced by CaCl equilibrium centrifugation. The virus suspended in 1M MgCl2 solution was stable against heating at 50 degrees C for 30 minutes, but not against freezing at -20 degrees C for 60 minutes. The virus was resistant to, and increased in infectivity after, treatment with 0.063 approximately 1.0% trypsin. These properties were consistent with those established for the reoviruses. Most affected cattle showed a significant rise of antibody titer against reovirus and bovine respiratory syncytial virus, whereas only a few of them presented a serological evidence for recent infection with parainfluenza virus type 3, bovine adenovirus type 7, and bovine parovirus.

    Monitoring of minimal residual disease (MRD) has become routine clinical practice in frontline treatment of virtually all childhood acute lymphoblastic leukemia (ALL) and in many adult ALL patients. MRD diagnostics has proven to be the strongest prognostic factor, allowing for risk group assignment into different treatment arms, ranging from significant treatment reduction to mild or strong intensification. Also in relapsed ALL patients and patients undergoing stem cell transplantation, MRD diagnostics is guiding treatment decisions. This is also why the efficacy of innovative drugs, such as antibodies and small molecules, are currently being evaluated with MRD diagnostics within clinical trials. In fact, MRD measurements might well be used as a surrogate end point, thereby significantly shortening the follow-up. The MRD techniques need to be sensitive (≤10(-4)), broadly applicable, accurate, reliable, fast, and affordable. Thus far, flow cytometry and polymerase chain reaction (PCR) analysis of rearranged immunoglobulin and T-cell receptor genes (allele-specific oligonucleotide [ASO]-PCR) are claimed to meet these criteria, but classical flow cytometry does not reach a solid 10(-4), whereas classical ASO-PCR is time-consuming and labor intensive. Therefore, 2 high-throughput technologies are being explored, ie, high-throughput sequencing and next-generation (multidimensional) flow cytometry, both evaluating millions of sequences or cells, respectively. Each of them has specific advantages and disadvantages.

    The first well-documented outbreak of acute methyl mercury (MeHg) poisoning by consumption of contaminated fish occurred in Minamata, Japan, in 1953. The clinical picture was officially recognized and called Minamata disease (MD) in 1956. However, 50 years later there are still arguments about the definition of MD in terms of clinical symptoms and extent of lesions. We provide a historical review of this epidemic and an update of the problem of MeHg toxicity. Since MeHg dispersed from Minamata to the Shiranui Sea, residents living around the sea were exposed to low-dose MeHg through fish consumption for about 20 years (at least from 1950 to 1968). These patients with chronic MeHg poisoning continue to complain of distal paresthesias of the extremities and the lips even 30 years after cessation of exposure to MeHg. Based on findings in these patients the symptoms and lesions in MeHg poisoning are reappraised. The persisting somatosensory disorders after discontinuation of exposure to MeHg were induced by diffuse damage to the somatosensory cortex, but not by damage to the peripheral nervous system, as previously believed.

    Laparoscopic splenectomy remains a technically demanding procedure. On patients with sickle cell disease (SCD), a post operative acute chest syndrome (ACS) can occur. The aim of the study was to look for predictive factors of post operative ACS. It's a retrospective study on patients with SCD, who underwent a laparoscopic splenectomy in Robert Debré hospital, Paris, France, between March 2008 and December 2013. Diagnosis of ACS was done if the patient developed hypoxemia associated with fever above 38.5 °C and an infiltrate on chest x ray during the post operative course. Pre-, post- and operative factors were studied. Descriptive statistics were compared using the Mann-Whitney test or the exact Fisher test. A p inferior to 0.05 was considered as significant. 52 patients with SCD underwent a laparoscopic splenectomy. Twelve patients presented a post operative ACS (23%) (mean age at surgery 4 years old) while forty did not (mean age 5.25 years old). Neither previous episode of ACS nor any factors reflecting SCD severity were significant. The shorter the operative time was, the greater the risk of developing an ACS (p post operative management, in the absence of predictive factors for ACS, should be carefully followed in a high dependency unit at least for 48 h for all patients.

    NOX-2, the catalytic subunit of NADPH oxidase, has a key role in the formation of reactive oxidant species and is implicated in impairing flow-mediated dilation (FMD). Dark chocolate exerts artery dilatation via down-regulating NOX2-mediated oxidative stress. The aim of this study was to investigate whether dark chocolate improves walking autonomy in peripheral artery disease (PAD) patients via an oxidative stress-mediated mechanism. FMD, serum levels of isoprostanes, nitrite/nitrate (NOx) and sNOX2-dp, a marker of blood NOX2 activity, maximal walking distance (MWD) and maximal walking time (MWT) were studied in 20 PAD patients (14 males and 6 females, mean age: 69±9 years) randomly allocated to 40 g of dark chocolate (>85% cocoa) or 40 g of milk chocolate (≤35% cocoa) in a single blind, cross-over design. The above variables were assessed at baseline and 2 hours after chocolate ingestion. Dark chocolate intake significantly increased MWD (+11%; Pchocolate intake. Serum epicatechin and its methylated metabolite significantly increased only after dark chocolate ingestion. Multiple linear regression analysis showed that Δ of MWD was independently associated with Δ of MWT (Pchocolate acutely improves walking autonomy with a mechanism possibly related to an oxidative stress-mediated mechanism involving NOX2 regulation. http://www.clinicaltrials.gov.

    Knowing about a diagnostic probability requires general knowledge about the way in which the probability depends on the diagnostic indicators involved in the specification of the case at issue. Diagnostic probability functions (DPFs) are generally unavailable at present. Our objective was to illustrate how diagnostic experts' case-specific tacit knowledge about diagnostic probabilities could be garnered in the form of DPFs. Focusing on diagnosis of acute coronary heart disease (ACHD), we presented doctors with extensive experience in hospitals' emergency departments a set of hypothetical cases specified in terms of an inclusive set of diagnostic indicators. We translated the medians of these experts' case-specific probabilities into a logistic DPF for ACHD. The principal result was the experts' typical diagnostic probability for ACHD as a joint function of the set of diagnostic indicators. A related result of note was the finding that the experts' probabilities in any given case had a surprising degree of variability. Garnering diagnostic experts' case-specific tacit knowledge about diagnostic probabilities in the form of DPFs is feasible to accomplish. Thus, once the methodology of this type of work has been "perfected," practice-guiding diagnostic expert systems can be developed. Copyright © 2013 Elsevier Inc. All rights reserved.

    Acquired drug resistance in childhood T-cell acute lymphoblastic leukemia (T-ALL) remains a significant clinical problem. In this study, a novel gene therapy target for childhood T-ALL to overcome chemoresistance was discovered: TFDP3 increased in the minimal residual disease (MRD) positive childhood T-ALL patients. Then, we established a preclinical model of resistance to induction therapy to examine the functional relevance of TFDP3 to chemoresistance in MRD derived from Jurkat/E6-1. Jurkat xenografts in NOD/SCID mice were exposed to a four drug combination (VXLD) of vincristine (VCR), dexamethasone (DEX), L-asparaginase (L-asp) and daunorubicin (DNR). During the 4-week VXLD treatment, the level of TFDP3 increased 4-fold. High expression of TFDP3 was identified in the re-emerging lines (Jurkat/MRD) with increased chemoresistance, which is correlated with partially promoter demethylation of TFDP3. Downregulation of TFDP3 by RNA interference reversed chemoresistance in Jurkat/MRD accompanied by reinstated E2F1 activity that coincided with increased levels of p53, p73, and associated proapoptotic target genes. Importantly, TFDP3 silencing in vivo induced apparent benefit to overcome chemoresistance in combination with VXLD treatment. Collectively, TFDP3 confers chemoresistance in MRD within childhood T-ALL, indicating that TFDP3 is a potential gene therapy target for residual cancer. PMID:27902457

    After allogeneic stem cell transplantation (SCT), a reliable diagnosis of acute graft versus host disease (aGvHD) is essential for an early and successful treatment. It is the aim of this analysis to assess intestinal aGvHD by magnetic resonance imaging (MRI). Prior to allogeneic SCT, 64 consecutive patients underwent abdominal MRI examination on a 3 T MR system, including axial and coronal T2w sequences and a three-dimensional dynamic T1w, contrast enhanced sequence. After SCT, 20 patients with suspected aGvHD received a second MRI as well as an endoscopic examination. Nine patients suffered from histologically proven intestinal aGvHD. In eleven patients intestinal aGvHD was excluded. In all aGvHD patients typical MRI findings with long-segment bowel wall thickening - always involving the terminal ileum - with profound submucosal oedema, were detected. The bowel wall was significantly thickened in patients with intestinal aGvHD. Bowel contrast enhancement spared the submucosa while demonstrating strong mucosal hyperemia. In intestinal aGvHD, a characteristic MR-appearance can be detected. This MRI pattern might facilitate an early and non-invasive diagnosis of intestinal aGvHD. MRI might thus be used as a sensitive tool to rule out or support the clinical diagnosis of aGvHD. (orig.)

    1984-01-01

    A series of 46 patients with obstructive disease of the bile ducts complicated by acute renal failure (ARF) is presented. The patients exhibited obstructive jaundice with prevalence of conjugated bilirubine. In 80% of the cases biliary obstruction was associated with cholangitis. Disturbances of the liver function (from mild cholestasis to biliary cirrhosis) were also present. The renal damage was due to biliary disorders and was either present on admission (33 cases) or developed postoperatively (13 cases). Most of the patients presented nonoliguric ARF as well as poor perfusion resulting from decreased circulating blood volume (dehydration and electrolyte loss). Among the criteria used to determine the type of ARF, the urinary/plasma creatinine ratio less than 10 and urinary/plasma osmolarity ratio less than 1.1 were the most valuable. Management of ARF by dialysis alone was not satisfactory. Attention is called to the surgical treatment of the biliary disorder as being essential to prognosis. Patients not treated by radical surgery died in proportion of 87 to 100%. From the rest of 18 patients in whom the operation provided an adequate biliary drainage, in 15 the renal function was restored and 12 survived. Better prognosis in these patients was dependent not only on the ability to cure the cholestasis and infection, but on the early surgical treatment. The ultimate prognosis depends on the improvement of the liver function.

    Acute kidney injury (AKI) is an important risk factor for incident chronic kidney disease (CKD). Clinical studies disclose that ensuing CKD progresses after functional recovery from AKI, but the underlying mechanisms remain illusive. Using a murine model representing AKI-CKD continuum, we show angiotensin II type 1a (AT1a) receptor signaling as one of the underlying mechanisms. Male adult CD-1 mice presented severe AKI with 20% mortality within 2 weeks after right nephrectomy and left renal ischemia-reperfusion injury. Despite functional recovery, focal tubular atrophy, interstitial cell infiltration and fibrosis, upregulation of genes encoding angiotensinogen and AT1a receptor were shown in kidneys 4 weeks after AKI. Thereafter mice manifested increase of blood pressure, albuminuria and azotemia progressively. Drinking water with or without losartan or hydralazine was administered to mice from 4 weeks after AKI. Increase of mortality, blood pressure, albuminuria, azotemia and kidney fibrosis was noted in mice with vehicle administration during the 5-month experimental period. On the contrary, these parameters in mice with losartan administration were reduced to the levels shown in control group. Hydralazine did not provide similar beneficial effect though blood pressure was controlled. These findings demonstrate that losartan can reduce ensuing CKD and mortality after functional recovery from AKI. PMID:27677327

    2011-01-01

    Full Text Available In acute myeloid leukemia (AML, the selection of poor-risk patients for allogeneic hematopoietic stem cell transplantation (HSCT is associated with rather high post-transplant relapse rates. As immunotherapeutic intervention is considered to be more effective before the cytomorphologic manifestation of relapse, post-transplant monitoring gains increasing attention in stem cell recipients with a previous diagnosis of AML. Different methods for detection of chimerism (e.g., microsatellite analysis or quantitative real-time PCR are available to quantify the ratio of donor and recipient cells in the post-transplant period. Various studies demonstrated the potential use of mixed chimerism kinetics to predict relapse of the AML. CD34+-specific chimerism is associated with a higher specificity of chimerism analysis. Nevertheless, a decrease of donor cells can have other causes as well. Therefore, efforts continue to introduce minimal residual disease (MRD monitoring based on molecular mutations in the post-transplant period. The NPM1 (nucleophosmin mutations can be monitored by sensitive quantitative real-time PCR in subsets of stem cell recipients with AML, but for approximately 20% of patients, suitable molecular mutations for post-transplant MRD monitoring are not available so far. This emphasizes the need for an expansion of the panel of MRD markers in the transplant setting.

    Pretreatment assessment of cytogenetic/genetic signature of acute myeloid leukemia (AML) has been consistently shown to play a major prognostic role but also to fail at predicting outcome on individual basis, even in low-risk AML. Therefore, we are in need of further accurate methods to refine the patients’ risk allocation process, distinguishing more adequately those who are likely to recur from those who are not. In this view, there is now evidence that the submicroscopic amounts of leukemic cells (called minimal residual disease, MRD), measured during the course of treatment, indicate the quality of response to therapy. Therefore, MRD might serve as an independent, additional biomarker to help to identify patients at higher risk of relapse. Detection of MRD requires the use of highly sensitive ancillary techniques, such as polymerase chain reaction (PCR) and multiparametric flow cytometry(MPFC). In the present manuscript, we will review the current approaches to investigate MRD and its clinical applications in AML management. PMID:27872732

    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.

    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.

    Purpose: To evaluate the use and findings of abdominal plain film in acute ischemic bowel disease (AIBD) in different age subsets, and to correlate the clinical findings. Material and Methods: Eighty-nine radiographically examined patients with AIBD at Malmoe University Hospital, Sweden between 1987 and 1996. Results: In 89%, the plain film displayed pathologic signs. Bowel dilatation was more common in the elderly. Of 68 patients aged <71 years, 19 (28%) had colon gas/fluid levels with/without colon dilatation, and of 19 patients >84 years 16 (84%) had small-bowel dilatation. Of 20 patients aged P P P = 0.001). Of the patients with diarrhea, 13 of 33 (40%) had colon gas/fluid levels with/without colon dilatation compared to 2 of 29 (7%) without (P = 0.003). In the elderly (>71 years), 48 of 53 (91%) patients with bowel dilatation on plain film died, compared to 11 out of 16 (69%) without this finding (P <0.05). Conclusion: Abdominal plain film findings differed with age. Bowel dilatation was more frequent in the elderly with AIBD, whereas gasless abdomen was more common in younger patients. The radiographic findings were associated with clinical symptoms and mortality.

    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

    Full Text Available Abstract Introduction Acute kidney injury in the setting of adult minimal change disease is associated with proteinuria, hypertension and hyperlipidemia but anemia is usually absent. Renal biopsies exhibit foot process effacement as well as tubular interstitial inflammation, acute tubular necrosis or intratubular obstruction. We recently managed a patient with unique clinical and pathological features of minimal change disease, who presented with severe anemia and acute kidney injury, an association not previously reported in the literature. Case presentation A 60-year-old Indian-American woman with a history of hypertension and diabetes mellitus for 10 years presented with progressive oliguria over 2 days. Laboratory data revealed severe hyperkalemia, azotemia, heavy proteinuria and progressively worsening anemia. Urine eosinophils were not seen. Emergent hemodialysis, erythropoietin and blood transfusion were initiated. Serologic tests for hepatitis B, hepatitis C, anti-nuclear antibodies, anti-glomerular basement membrane antibodies and anti-neutrophil cytoplasmic antibodies were negative. Complement levels (C3, C4 and CH50 were normal. Renal biopsy unexpectedly displayed 100% foot process effacement. A 24-hour urine collection detected 6.38 g of protein. Proteinuria and anemia resolved during six weeks of steroid therapy. Renal function recovered completely. No signs of relapse were observed at 8-month follow-up. Conclusion Adult minimal change disease should be considered when a patient presents with proteinuria and severe acute kidney injury even when accompanied by severe anemia. This report adds to a growing body of literature suggesting that in addition to steroid therapy, prompt initiation of erythropoietin therapy may facilitate full recovery of renal function in acute kidney injury.

    Several forms of arthritis and rheumatism can sometimes complicate leprosy. However, its presentation as an acute onset arthritis is unusual. We report two adult male naïve patients who presented to our rheumatology outpatient clinic with acute onset inflammatory polyarthritis, skin rash and mild sensory neurodeficit. Borderline lepromatous leprosy (in type I lepra reaction) was diagnosed. We also refer to 19 case records of Hansen arthritis in the clinic database (1998-2007) from approximately 35,000 patients and a community study to highlight the missed diagnosis of Hansen's disease and its unusual association with rheumatoid arthritis. In countries like India where leprosy is endemic, this disease also merits attention in rheumatology clinics.

  6. Genetic and metabolic signals during acute enteric bacterial infection alter the microbiota and drive progression to chronic inflammatory disease

    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.

  7. Changes in ion transport in inflammatory disease

    Full Text Available Abstract Ion transport is essential for maintenance of transmembranous and transcellular electric potential, fluid transport and cellular volume. Disturbance of ion transport has been associated with cellular dysfunction, intra and extracellular edema and abnormalities of epithelial surface liquid volume. There is increasing evidence that conditions characterized by an intense local or systemic inflammatory response are associated with abnormal ion transport. This abnormal ion transport has been involved in the pathogenesis of conditions like hypovolemia due to fluid losses, hyponatremia and hypokalemia in diarrhoeal diseases, electrolyte abnormalites in pyelonephritis of early infancy, septicemia induced pulmonary edema, and in hypersecretion and edema induced by inflammatory reactions of the mucosa of the upper respiratory tract. Components of membranous ion transport systems, which have been shown to undergo a change in function during an inflammatory response include the sodium potassium ATPase, the epithelial sodium channel, the Cystic Fibrosis Transmembrane Conductance Regulator and calcium activated chloride channels and the sodium potassium chloride co-transporter. Inflammatory mediators, which influence ion transport are tumor necrosis factor, gamma interferon, interleukins, transforming growth factor, leukotrienes and bradykinin. They trigger the release of specific messengers like prostaglandins, nitric oxide and histamine which alter ion transport system function through specific receptors, intracellular second messengers and protein kinases. This review summarizes data on in vivo measurements of changes in ion transport in acute inflammatory conditions and in vitro studies, which have explored the underlying mechanisms. Potential interventions directed at a correction of the observed abnormalities are discussed.

    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.

    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.

    Two-tier serology is often used to confirm a diagnosis of Lyme disease. One hundred and four patients with physician diagnosed erythema migrans rashes had blood samples taken before and after 3 weeks of doxycycline treatment for early Lyme disease. Acute and convalescent serologies for Borrelia burgdorferi were interpreted according to the 2-tier antibody testing criteria proposed by the Centers for Disease Control and Prevention. Serostatus was compared across several clinical and demographic variables both pre- and post-treatment. Forty-one patients (39.4%) were seronegative both before and after treatment. The majority of seropositive individuals on both acute and convalescent serology had a positive IgM western blot and a negative IgG western blot. IgG seroconversion on western blot was infrequent. Among the baseline variables included in the analysis, disseminated lesions (p Lyme disease. Furthermore, these findings underline the difficulty for rheumatologists in identifying a prior exposure to Lyme disease in caring for patients with medically unexplained symptoms or fibromyalgia-like syndromes.

    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. 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. 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. 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 (parterial 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,O, and Sv,O2 cannot be used as predictors in the assessment of oxygen status of such patients.

    Full Text Available Inhalations (inhalation of medicinal substances are one of the effective ways to treat upper respiratory tract diseases and colds. Inhalation therapy is used to treat rhinitis, sinusitis, tonsillitis, pharyngitis, laryngitis, bronchitis and pneumonia, which can be complications of acute respiratory viral infections. The main rules of inhalation are as follows to conduct the procedure better after 1.5 hours after eating; clothes should not impede breathing; the procedure can be carried out only while sitting or standing; solution for the inhaler for treatment of bronchitis should be fresh; it is necessary to strictly keep the prescribed dosage; the time of the procedure should also be respected — usually it is from 1 to 4 minutes, sometimes for adults up to 10 minutes, for children the inhalation period is shorter — 1–2 minutes. Contraindications to inhalation are body temperature above 37.5 degrees; propensity to nasal blee­ding in a patient; propensity to increased arterial pressure, with cardiovascular failure; purulent inflammation of the tonsils; respiratory failure. The procedure should be stopped immediately in case of appearance of adverse symptoms such as shortness of breath, dizziness, difficulty in breathing. Therefore, inhalations must be prescribed by a doctor after examination of a patient. During inhalations in rhinitis, you should try to inhale the vapor through the nose. For effective treatment of rhinitis, inhalations from conife­rous plants are very suitable: fir, pine, juniper, larch, from steamed dried chamomile flowers, mint, and blackberry leaves. Honey inhalations can be used for the treatment of acute and chronic diseases of the upper respiratory tract (tonsillitis, pharyngitis, laryngitis and tracheitis. Medical herbal inhalation for children should be carried out from the age of two years. This must be done under the constant supervision of an adult.

    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

    Patients with gastroesophageal reflux disease (GERD) present with comorbid complications with implications for healthcare utilization. To date, little is known about the effects of GERD treatment with a proton-pump inhibitor (PPI) on patients’ subsequent healthcare utilization for acute respiratory infections (ARIs). This population-based study compared ARI episodes captured through outpatient visits, one year before and one year after GERD patients received PPI treatment. We used retrospective data from the Longitudinal Health Insurance Database 2005 in Taiwan, comparing 21,486 patients diagnosed with GERD from 2010 to 2012 with 21,486 age-sex matched comparison patients without GERD. Annual ARI episodes represented by ambulatory care visits for ARI (visits during a 7-day period bundled into one episode), were compared between the patient groups during the 1-year period before and after the index date (date of GERD diagnosis for study patients, first ambulatory visit in the same year for their matched comparison counterpart). Multiple regression analysis using a difference-in-difference approach was performed to estimate the adjusted association between GERD treatment and the subsequent annual ARI rate. We found that the mean annual ARI episode rate among GERD patients reduced by 11.4%, from 4.39 before PPI treatment, to 3.89 following treatment (mean change = -0.5 visit, 95% confidence interval (CI) = (-0.64, -0.36)). In Poisson regression analysis, GERD treatment showed an independent association with the annual ARI rate, showing a negative estimate (with p<0.001). The study suggests that GERD treatment with PPIs may help reduce healthcare visits for ARIs, highlighting the importance of treatment-seeking by GERD patients and compliance with treatment.

    Acute graft-versus-host disease (aGVHD) is a serious complication of allogeneic hematopoietic stem cell transplantation (allo-HSCT). Our previous study found that the novel anti-inflammatory cytokine IL-35 could suppress aGVHD in patients after allo-HSCT. In this study, we used C57BL/6 (B6, H-2b) mice as donors and (B6×DBA/2) F1 (BDF1, H-2b×d) mice as recipients to create a model of aGVHD and explore the relationship between IL-35 and aGVHD. The mice receiving IL-35 survived longer than did the control mice. We observed that treatment with IL-35 and RAPA could reduce the incidence of aGVHD. Additionally, this treatment inhibited intestinal and thymic epithelial cell apoptosis and liver infiltration by the donor T-cells, thereby ameliorating the enteropathy and liver injury caused by aGVHD. We found that IL-35 and RAPA also markedly suppressed TNF-α and IL-17A expression and enhanced IFN-γ expression in the intestine and liver. We measured Tregs in spleen and found that IL-35 and RAPA treatment expanded the number of Tregs in spleen. We found that the phosphorylation of STAT1 and STAT4 were inhibited in mice with aGVHD. In contrast, STAT1 and STAT4 were phosphorylated when the mice were treated with IL-35. IL-35 may have therapeutic potential in the treatment of aGVHD after allo-HSCT.

    Full Text Available We describe a case with macular hole (MH associated with Vogt-Koyanagi-Harada (VKH disease. A 71-year-old Japanese woman presented with visual loss and headaches. The best-corrected visual acuity (BCVA was 0.02 in the right eye (RE and 0.1 in the left eye (LE. The patient was diagnosed with VKH based on circumferential choroidal detachments, multiple serous retinal detachments, and optic disc hyperemia. The multiple serous retinal detachments improved with high-dose corticosteroid therapy and gradual tapering. The BCVA was recovered to 1.2/0.7 in the RE/LE. Six weeks after the initial administration of steroid, vitreomacular traction was found by optical coherence tomography in the LE, which progressed to stage 4 MH with the BCVA of 0.2 in the LE. Twenty-three weeks after the initial treatment, vitrectomy was performed with the standard surgical procedures, including inner limiting membrane peeling around the fovea and air tamponade. The MH was closed successfully and the BCVA was 0.4 in the LE 5 weeks after the vitrectomy. This is the first report of a case with MH secondary to the acute uveitic stage of VKH. Successful closure of MH was achieved with the standard surgical intervention for an idiopathic MH. To conclude, at the early stage of VKH, there is a possibility of MH formation due to the rapid progress of vitreous traction following the inflammation, and the surgical procedure could be effective to resolve this secondary disorder.

    Full Text Available Background: Acute Lower Respiratory Tract Infection (ALRTI is the leading cause of deaths in children under 5 years of age worldwide, and has high morbidity and mortality in children with Congenital Heart Disease (CHD. The objective of this study was to obtain the incidence, clinical characteristic, and outcome of ALRTI children with CHD. Methods: A retrospective hospital-based study was conducted from January 2007–December 2011 to medical record of child patients with ALRTI and CHD in the Department of Child Health of Dr. Hasan Sadikin General Hospital, Bandung. The diagnosis of CHD was determined by echocardiography. The collected data was analyzed and presented in percentage shown in tables. Results : From 3,897 children who had ALRTI, there were 149 children with CHD (3.8%, with 11.4% of whom founded with recurrent episodes. This happened often in girls than boys with quite similar ratio of 1.37: 1.The majority of children (80% was under 1 year old of age, 72.5% with malnutrition, and 24.8% with severe malnutrition. Clinical symptoms mostly found were difficulty of breathing (98%, fever (85.2%, cough (75.2%, and runny nose (63.1%. The most common types of CHD were Patent Ductus Arteriosus (47.6%, followed by Ventricular Septal Defect (47%. Bronchopneumonia (86.6% was the common type of ALRTI. The length of stay was mostly less than 10 days (70.5%. From all the children 43.7% had complications, and 6.7% died. Conclusions: The ALRTI in children with CHD is not common and has good outcome. The majority for CHD lesions are Patent Ductus Arteriosus and Ventricular Septal Defect while for ALRTI is Bronchopneumonia.

    Erdosteine has positive effects on mucus rheology and transport due to the active metabolite (Metabolite I) which contains a free thiol group. Erdosteine inhibits bacterial adhesiveness and has antioxidant properties. A synergistic effect of erdosteine with various antibiotics has been demonstrated in pharmacological and clinical studies. The present study was multicenter, randomized, double-blind and placebo-controlled. The aims of the study were to compare a combination of erdosteine with amoxicillin against an amoxicillin-placebo combination in pediatric patients with acute lower respiratory tract disease. A total of 158 patients (78 in the erdosteine group and 80 in the placebo group) were treated for 7 +/- 2 days. The efficacy parameters were cough (primary), polypnea, rhonchi, rales and body temperature (all measured at baseline, on Day 3 and at the end of treatment). Safety was assessed by strictly monitoring the occurrence of adverse events and using standard laboratory parameters. The results of the intention-to-treat analysis showed that the severity of cough was decreased by 47% at Day 3 in the erdosteine group with a statistically significant difference compared to placebo, the difference was still significant at the final visit. The decrease in the severity of rales was significantly greater at Day 3 in the erdosteine group than in the placebo group. The incidence of polypnea and rhonchi in the two groups showed similar decreases, an improvement mainly due to the antibiotic. No adverse events occurred and no adverse changes in laboratory parameters were observed. It is concluded that the combination of erdosteine and amoxicillin is a safe medication which is clinically superior to that of the antibiotic combined with placebo, especially in regard to the effects on cough.

    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.

    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.

  11. [Globosides as key players in the pathophysiology of Shiga toxin-associated acute kidney failure and Fabry disease].

    Globosides and their isomeric counterparts isoglobosides belong to the class of neutral glycosphingolipids with an as yet undefined physiological function. In the pathogenesis of human diseases, globosides play an important role as cellular receptors for Shiga toxins which are produced by certain strains of S. dysenteriae and E. coli. In order to elucidate the pathogenesis of Shiga toxin-associated kidney failure, we studied human kidney biopsies and animal models. Our work showed that in patients suffering from Shiga toxin-elicited kidney failure, no complement activation could be demonstrated by immunohistochemical analysis of kidney biopsies. Therefore, complement activation is unlikely to play a major role in mediating thrombotic microangiopathy on exposure to Shiga toxin. Moreover, analysis of the human biopsies and of a murine model of Shiga toxin-associated disease pinpointed acute tubular damage as an important and previously neglected contributor to acute kidney failure in patients infected with Shiga toxin-producing E. coli. Furthermore, globosides play a decisive role in the pathogenesis of Fabry disease which results from a decreased or absent activity of the lysosomal enzyme α-galactosidase A. The results on transgenic mice showed that in vital organs, such as the heart, kidneys and liver, it was possible to revert the phenotype of Fabry disease by eliminating the synthesis of globosides. This implicates that substrate reduction therapy through inhibition of globosides might represent a new therapeutic option for Fabry disease, all the more so as globosides seem to be dispensable.

    Kawasaki disease is a vasculitis most commonly afflicting children Kawasaki disease. Blood samples were obtained from 186 children with Kawasaki disease at 24 h before IVIG therapy, followed by 3 days and 21 days after IVIG therapy. Thirty children with an acute febrile infectious disease and 30 healthy children were obtained as control. Plasma levels of Th17- and Treg-related cytokines including IL-6, IL-17A, IL-10, TGF-β, and mRNA expression levels of RORγt and Foxp3 were tested. Patients with Kawasaki disease had higher levels of plasma IL-17A (25.35 ± 3.21 vs 7.78 ± 1.78 pg/ml, P Kawasaki disease was associated with higher IL-17A and IL-6, a cytokine profile similar to other autoimmune diseases. IVIG therapy resulted in increased expression of Treg-related FoxP3. IVIG resistance was associated with higher levels of IL-10 and IL-17A. Our findings provide further evidence that Kawasaki disease is an autoimmune-like disease. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    The IgG4-related disease has a wide clinical spectrum where multiple organs can be affected, and the diagnosis depends on typical histopathological findings and an elevated IgG4 expression in plasma cells in the affected tissue. We describe the clinical presentation and evolution of a patient with acute tubulointerstitial nephritis, severe kidney failure and systemic manifestations such as lymphadenomegaly and chronic pancreatitis. The diagnosis was confirmed by the clinical picture and kidney and lymph node histopathology, in which immunohistochemistry of the lymphoid tissue showed policlonality and increased expression of IgG4, with a IgG4/total IgG ratio > 80%. The patient was treated with prednisone at a dose of 60 mg/day, followed by mycophenolate mofetil, and showed clinical and renal function improvement at 6 months of follow-up. The high index of suspicion of IgG4-related disease with multisystem involvement and the early treatment of this condition are essential to improve the prognosis of affected patients. Resumo A doença relacionada à IgG4 tem um espectro clínico amplo em que múltiplos órgãos podem ser afetados, e o diagnóstico depende de achados histopatológicos típicos e elevada expressão de IgG4 em plasmócitos no tecido afetado.

    This document outlines the usefulness of available diagnostic imaging for patients without known coronary artery disease and at low probability for having coronary artery disease who do not present with classic signs, symptoms, or electrocardiographic abnormalities indicating acute coronary syndrome but rather with nonspecific chest pain leading to a differential diagnosis, including pulmonary, gastrointestinal, or musculoskeletal pathologies. A number of imaging modalities are available to evaluate the broad spectrum of possible pathologies in these patients, such as chest radiography, multidetector CT, MRI, ventilation-perfusion scans, cardiac perfusion scintigraphy, transesophageal and transthoracic echocardiography, PET, spine and rib radiography, barium esophageal and upper gastrointestinal studies, and abdominal ultrasound. It is considered appropriate to start the assessment of these patients with a low-cost, low-risk diagnostic test such as a chest x-ray. Contrast-enhanced gated cardiac and ungated thoracic multidetector CT as well as transthoracic echocardiography are also usually considered as appropriate in the evaluation of these patients as a second step if necessary. A number of rest and stress single-photon emission CT myocardial perfusion imaging, ventilation-perfusion scanning, aortic and chest MR angiographic, and more specific x-ray and abdominal examinations may be appropriate as a third layer of testing, whereas MRI of the heart or coronary arteries and invasive testing such as transesophageal echocardiography or selective coronary angiography are not considered appropriate in these patients. Given the low risk of these patients, it is mandated to minimize radiation exposure as much as possible using advanced and appropriate testing protocols. The ACR Appropriateness Criteria® are evidence-based guidelines for specific clinical conditions that are reviewed every 2 years by a multidisciplinary expert panel.

    Star fruit (Averrhoa carambola) is commonly consumed as a herbal remedy for various ailments in tropical countries. However, the dangers associated with consumption of star fruit are not commonly known. Although star fruit induced oxalate nephrotoxicity in those with existing renal impairment is well documented, reports on its effect on those with normal renal function are infrequent. We report two unique clinical presentation patterns of star fruit nephrotoxicity following consumption of the fruit as a remedy for diabetes mellitus-the first, in a patient with normal renal function and the second case which we believe is the first reported case of chronic kidney disease (CKD) due to prolonged and excessive consumption of star fruits. The first patient is a 56-year-old female diabetic patient who had normal renal function prior to developing acute kidney injury (AKI) after consuming large amount of star fruit juice at once. The second patient, a 60-year-old male, also diabetic presented with acute on chronic renal failure following ingestion of a significant number of star fruits in a short duration with a background history of regular star fruit consumption over the past 2-3 years. Both had histologically confirmed oxalate induced renal injury. The former had histological features of acute tubulo-interstitial disease whilst the latter had acute-on-chronic interstitial disease; neither had histological evidence of diabetic nephropathy. Both recovered over 2 weeks without the need for haemodialysis. These cases illustrate the importance of obtaining the patient's detailed history with respect to ingestion of herbs, traditional medication and health foods such as star fruits especially in AKI or CKD of unknown cause.

    Nearly a third of patients with acute heart failure experience concomitant renal dysfunction. This condition is often associated with increased costs of care, length of hospitalisation and high mortality. Although the clinical impact of chronic kidney disease (CKD) has been well established, the exact clinical significance of worsening renal function (WRF) during the acute and post-hospitalisation phases is not completely understood. Therefore, it is still unclear which of the common laboratory markers are able to identify WRF at an early stage. Recent studies comparing CKD with WRF showed contradictory results; this could depend on a different WRF definition, clinical characteristics, haemodynamic disorders and the presence of prior renal dysfunction in the population enrolled. The current definition of acute cardiorenal syndrome focuses on both the heart and kidney but it lacks precise laboratory marker cut-offs and a specific diagnostic approach. WRF and CKD could represent different pathophysiological mechanisms in the setting of acute heart failure; the traditional view includes reduced cardiac output with systemic and renal vasoconstriction. Nevertheless, it has become a mixed model that encompasses both forward and backward haemodynamic dysfunction. Increased central venous pressure, renal congestion with tubular obliteration, tubulo-glomerular feedback and increased abdominal pressure are all potential additional contributors. The impact of WRF on patients who experience preserved renal function and individuals affected with CKD is currently unknown. Therefore it is extremely important to understand the origins, the clinical significance and the prognostic impact of WRF on CKD.

    A subset of 299 patients with homozygous sickle cell anaemia, enrolled in the cohort of the French Study Group on sickle cell disease (SCD), was investigated in this study. The majority of patients were children (mean age 10.1 +/- 5.8 yr) of first generation immigrants from Western and Central Africa, the others originated from the French West Indies (20.2%). We report the frequency of the main clinical events (mean follow-up 4.2 +/- 2.2 yr). The prevalence of meningitis-septicaemia and osteomyelitis was, respectively, 11.4% and 12% acute chest syndrome was observed in 134 patients (44.8%). Twenty patients (6.7%) developed stroke with peak prevalence at 10-15 yr of age. One hundred and seventy-two patients (58%) suffered from one or more painful sickle cell crises, while the others (42.5%) never suffered from pain. The overall frequency of acute anaemic episodes was 50.5%, (acute aplastic anaemia 46%; acute splenic sequestration 26%). A group of 27 patients were asymptomatic (follow-up > 3 yr). Epistatic mechanisms influencing SCD were studied. Coinherited alpha-thalassemia strongly reduced the risk of stroke (p haplotype strongly reflects the geographic origin and identifies subgroups with a homogenous genetic background. Thus the observed effects might result more from differences in as yet unidentified determinants in the genetic background than from the direct linkage with differences in the beta-globin gene locus.

    Stroke and acute myocardial infarction are the leading causes of death and disability in industrialized countries. Multiple interactions exist between the various forms of cardiovascular and cerebrovascular diseases, and risk factors for development of stroke and major cardiovascular events are similar. There is currently no clear link between acute coronary syndrome and stroke, although it has been repeatedly described. In addition, there are currently no clear recommendations for how to proceed in the case of signs of myocardial damage in patients with acute stroke and how to manage the next follow-up. METHODS-DESIGN: In this prospective observational trial, 500 consecutive ischemic stroke patients admitted at the Comprehensive Stroke Center will be enrolled within 12 h from stroke onset. The set of examinations will consist of: 1) Acute brain computed tomography or magnetic resonance imaging 2) Laboratory tests: A) within 12 h from stroke onset: NT pro B-type of natriuretic peptide, pro-atrial natriuretic peptide, creatinekinase MB, troponin T (cTnT), interleukin 6, procalcitonin, high sensitive C-reactive protein and D-dimers. B) control level of cTnT after 4 h from admission C) non-acute laboratory samples within 60 h from stroke onset: glycated haemoglobine, serum lipids; 3) Electrocardiogram (ECG) on admission and 4 h from stroke onset; 4) Transesophageal or transthoracal echocardiography and 24-h ECG-Holter within 15 days from stroke onset; 5) Neurosonological examination within 60 h from stroke onset; 6) Thirty patients with a positive finding of acute myocardial ischemia (ECG, cTnT) will be examined by coronary angiography (CAG); 7) Epidemiological data will be acquired. The epidemiological characteristics of the whole sample of patients; correlation between differences between group of cardioembolic ischemic stroke patients and group of patients with ischemic stroke of another etiology; correlation of infarction volume on DWI-MRI with the level of c
