The epidemiology and etiology of acute diarrheal disease were determined in a Hmong refugee camp on the Thai-Laotian border from April 11 to May 14, 1985. DNA hybridization techniques were used to detect Shigella species, enteroinvasive Escherichia coli, and enterotoxigenic E. coli. A monoclonal enzyme-linked immunosorbent assay was used to detect rotavirus, and standard microbiology was used to detect other enteropathogens. The age-specific diarrheal disease rates were 47 episodes per month per 1000 children less than five years old and 113 episodes per month per 1000 children less than one year old. Rotavirus, enterotoxigenic E. coli, Campylobacter, and Cryptosporidium were the predominant pathogens in children less than two years old. The DNA probe hybridized with 94% of 31 specimens identified as enterotoxigenic E. coli by the standard assays and with none of the specimens in which the standard assays were negative. The probe for Shigella and enteroinvasive E. coli hybridized in eight of 10 stools that contained Shigella and four of 314 stools from which Shigella and enteroinvasive E. coli were not isolated. The use of DNA probes allows specimens to be collected in remote areas with a minimum amount of equipment and technical expertise so that they can be easily transported to a central laboratory for further processing.

Diarrheal disease is the commonchildhood illness and a leading killer of children aged under 5 years, especially in developing countries like Ethiopia. The aim of this study was to assess the prevalence of diarrheal disease and associated risk factors among children of 6-59 months old at Adama district rural kebeles, Eastern Ethiopia. Community based cross sectional study design was conducted in January/2015. Descriptive method was used to describe study variables quantitatively and explanatory method to identify the effect of determinant factors on diarrheal disease occurrence. A single population proportion sample size formula was applied. Random sampling procedure was used by lottery method to select five kebeles and 442 house-holds. Data was collected by using pretested, structured questionnaires through interview and observational checklist by trained data collectors. Double entry was made to epi-info 3.5.3 and & transferred to SPSS20 for analysis. The two weeks' period prevalence of diarrheal disease in children aged 6 to59 months was 14.7%; 95%CI [11.5-18.1]. mother/caregiver who did not practice hand washing during the critical time was the only factor identified to be significantly associated with AOR=2.2; 95%CI [1.0-4.7] for the child hood diarrheal disease occurrence at Adama distict rural kebeles. Diarrheal disease prevalence is changed by child's caregiver hand washing practice during critical time. Health education for child's caregiver on hand washing practice during critical time is an important intervention for the prevention of diarrheal disease prevalence among children.

In 1980 the Ministry of Health of Egypt undertook a short term investigation into means and methods to reduce the annually excessive number of preschool child deaths from Diarrheal Disease. This investigation sought to identify ways to overcome constraints related to logistics, supplies, and community participation. The unifying theme of this study was to examine the feasibility of stressing Oral Rehydration Therapy (ORT) instead of the then conventional parenteral treatment and heavy use of antibiotics. Study cells were arranged to test feasibility of placing responsibility for the intervention primarily with rural mothers, secondly with itinerant nurses. Appropriate health education programs, revised supervision and data collection systems were developed and implemented. Results limited to mortality indicators demonstrating that mothers could affect a significant decrease in the diarrhea-specific death rate were reported in an earlier paper. In this paper a more comprehensive presentation of various survey data associated with the investigation are presented. These data show that mothers were indeed able to recognize diarrheal disease and institute early and effective treatment, and that they developed remarkable skills of preparing safe oral rehydration fluids from home supplies of sugar and salt. In addition, the data show that health service staff increasingly gained confidence in ORT as demonstrated by increasing rates of utilization of the method, and as mothers indicated ORT to be the preferred method of treatment of diarrheal disease.

Between May and July 1987, we studied 36 children with second or third degree dehydration secondary to acute diarrheal disease of less than one week duration; they had no serious associated problems. Parenteral rehydration was carried out with a solution similar in composition to the one recommended by the World Health Organization for Oral Rehydration Therapy (ORT. Rehydration was achieved in 30 patients within 6 hours and In 3 more within 12 hours; there were no cases of hypernatremia or hyperkalemia. It is concluded that parenteral rehydration with a solution similar to the one employed for ORT is an adequate alternative when oral rehydration is not indicated in children with diarrheal disease.

Entre mayo y julio de 1987 se estudiaron 36 niños que ingresaron al Hospital Infantil de Medellín con deshidratación de segundo o tercer grado, secundaria a enfermedad diarreica de evolución menor de una semana y sin enfermedad grave asociada. La hidratación se llevó a cabo parenteralmente empleando una mezcla de composición similar a la que recomienda la Organización Mundial de la Salud para la Terapia de Rehidratación Oral (TRO. Se logró la hidratación en un lapso de 6 horas en 30 de los 36 pacientes y en 3 más en las siguientes 6 horas; no se produjeron casos de hipernatremia ni de hiperkalemia. Se concluye que la hidratación parenteral, con una solución de composición similar a la de la TRO, es una alternativa adecuada cuando no está indicada la hidratación oral del niño con enfermedad diarreica.

Emergence of increased antimicrobial resistance of Shigella species is a global challenge, particularly in developing countries where increased misuse of antimicrobial agents occurs. There is no published data in the study area on the prevalence and antimicrobial susceptibility patterns of Shigella among acute diarrheal patients. This study was therefore, under taken to fill this gap. Using cross sectional study method, stool specimens were collected from 216 patients with acute diarrhea at Mekelle Hospital from August to November 2014. Standard bacteriological methods were used to isolate and determine the antimicrobial susceptibility patterns of the isolates, and data were analyzed using SPSS version 20. Out of the total 216 participants, Shigella was isolated from 15 (6.9 %) of the participants. Ten (66.7 %) of the positive isolates were from children Shigella showed 100, 86.7 and 66.7 % resistance to amoxicillin, amoxicillin and cotrimoxazole respectively. Low levels of resistance were observed for norfloxacin and ciprofloxacin (6.7 % each). Overall, 80 % of the isolates showed multidrug resistance. Shigella isolates were highly resistant to amoxicillin, amoxicillin and cotrimoxazole. However, ciprofloxacin and norfloxacin were effective. Antibiotic surveillance is needed to prevent further emergence of drug resistant Shigella strains. More has to be done in the availability of latrine, supply of safe drinking water to the community to reduce the disease burden.

The purpose of this study was to determine the association between deaths owing to terrorism, civil war and one-sided violence from 1994-2000 and disability-adjusted life years (DALYs) attributable to diarrheal and related diseases, schistosomiasis, trachoma and the nematode infections (DSTN diseases) in 2002 among World Health Organization Member States. Deaths resulting from terrorism, civil war and one-sided violence were significantly related to DSTN DALYs across the majority of sex-age subgroups of the populace, after controlling for baseline levels of improved water/sanitation and a variety of economic measures: overall, a 1.0% increase in deaths owing to terrorism and related violence was associated with an increase of 0.16% in DALYs lost to DSTN diseases. Associations were greatest among 0-to-4-year olds. The results of the present study suggest that DSTN disease control efforts should target conflict-affected populations with particular attention to young children who suffer disproportionately from DSTN diseases in these settings. In view of the evidence that terrorism and related violence may influence DSTN DALYs in the longer term, control strategies should move beyond immediate responses to decrease the incidence and severity of DSTN diseases to seek solutions through bolstering health systems infrastructure development among conflict-affected populations.

Endocrine disruptors such as phenolic compounds and parabens may be involved in chronic non-infective disease. While products incorporating these compounds are extensively utilized in consumer and personal products, little is known about their effect on bowel health. Inflammatory bowel disease (IBD) - consisting of the diseases ulcerative colitis and Crohn's disease - and irritable bowel syndrome are common chronic non-infectious diarrheal diseases. Despite limited knowledge on the etiology of IBD, these diseases have increased prevalence in industrialized countries and cause significant impairment to quality of life. In the present study we examine relationships between urinary environmental phenolic compounds, chronic diarrhea and inflammatory bowel disease. Data was obtained from the 2005–2010 US National Health and Nutrition Examination Survey (NHANES) including demographics, lifestyle factors, self-reported health conditions, inflammatory markers and urinary phenolic chemical concentrations. Only participants with complete environmental phenols & parabens component were included in our analysis. Chronic diarrheal symptoms were determined by using the 2009–2010 NHANES questionnaire which included questions pertaining to bowel health. We utilized chronic bowel leakage symptoms as a surrogate marker for chronic diarrhea. The presence of IBD was also analyzed from 2009 to 2010 NHANES data, as a sub-analysis for arthropathy directly querying the presence or absence of IBD. Among the subset of 5218 American adults aged 20–80 years in the NHANES study period who completed environmental phenols & parabens component, 25.5% reported chronic diarrheal symptoms. Abnormal markers of inflammation were present in 2200 (42.2%) of respondents. For IBD, 19 individuals with arthropathy confirmed a diagnosis of ulcerative colitis, and 1 person confirmed a Crohn's diagnosis. After adjustment for demographics, inflammatory and subsample weighing; lower paraben

Full Text Available Chrysomya spp are common blowflies in Africa, Asia and parts of South America and some species can reproduce in prodigious numbers in pit latrines. Because of their strong association with human feces and their synanthropic nature, we examined whether these flies are likely to be vectors of diarrheal pathogens.Flies were sampled using exit traps placed over the drop holes of latrines in Gambian villages. Odor-baited fly traps were used to determine the relative attractiveness of different breeding and feeding media. The presence of bacteria on flies was confirmed by culture and bacterial DNA identified using PCR. A median of 7.00 flies/latrine/day (IQR = 0.0-25.25 was collected, of which 95% were Chrysomya spp, and of these nearly all were Chrysomya putoria (99%. More flies were collected from traps with feces from young children (median = 3.0, IQR = 1.75-10.75 and dogs (median = 1.50, IQR = 0.0-13.25 than from herbivores (median = 0.0, IQR = 0.0-0.0; goat, horse, cow and calf; p<0.001. Flies were strongly attracted to raw meat (median = 44.5, IQR = 26.25-143.00 compared with fish (median = 0.0, IQR = 0.0-19.75, ns, cooked and uncooked rice, and mangoes (median = 0.0, IQR = 0.0-0.0; p<0.001. Escherichia coli were cultured from the surface of 21% (15/72 agar plates of Chrysomya spp and 10% of these were enterotoxigenic. Enteroaggregative E. coli were identified by PCR in 2% of homogenized Chrysomya spp, Shigella spp in 1.4% and Salmonella spp in 0.6% of samples.The large numbers of C. putoria that can emerge from pit latrines, the presence of enteric pathogens on flies, and their strong attraction to raw meat and fish suggests these flies may be common vectors of diarrheal diseases in Africa.

Full Text Available Advances have occurred in relation to the coverage of water supply and sanitation in Brazil, however inequalities are still observed in relation to the coverage of these services, reflecting the importance of diarrheal disease in the Brazilian epidemiological context. The aim of this study was to measure the impact of the water supply and sanitation system on diarrheal diseases among children aged under five. The global burden of diarrhea was calculated based on the attributable population fraction, using information on prevalence and relative risks from the 2000/2010 censuses and a study by Pruss et al. The north of the State of Minas Gerais, the Northeast and Jequitinhonha regions had the highest disability-adjusted life year (DALY rates and ratios. The fraction of diarrhea attributable to the water supply and sanitation system was 83%, decreasing to 78.3% where sanitation had 100% coverage. An inverse relationship was found between DALY rates and attributable fractions and per capita GDP. Broadening the scope and coverage of services and improving the quality of water available in homes is an urgent requirement. These measures will bring economic and social benefits related to the reduction of diarrheal diseases and consequent improvement of the quality of life of children aged under five.

Full Text Available The frequency of acute respiratory infections remains high in childhood. It is impossible to identify etiology most accurately in each particular case. However, according to multiple studies, viruses, their associations with each other and bacteria prevail as causative agents. In addition, it is quite often that a respiratory infection, especially in minor children, is combined with a condition of the gastrointestinal tract. Apart from symptomatic and antiviral therapies in these cases, as the authors of this article demonstrated, it is advisable to use enterosorbents. This tactics results in a decreased level of intoxication, lower intensity and duration of diarrheal syndrome, i.e. more speedy recovery.Key words: acute respiratory infections, condition of gastro tract, intoxication, diarrheal syndrome, treatment, enterosorbents, children.

A randomized, controlled intervention trial of two household-scale drinking water filters was conducted in a rural village in Cambodia. After collecting four weeks of baseline data on household water quality, diarrheal disease, and other data related to water use and handling practices, households were randomly assigned to one of three groups of 60 households: those receiving a ceramic water purifier (CWP), those receiving a second filter employing an iron-rich ceramic (CWP-Fe), and a control group receiving no intervention. Households were followed for 18 weeks post-baseline with biweekly follow-up. Households using either filter reported significantly less diarrheal disease during the study compared with a control group of households without filters as indicated by longitudinal prevalence ratios CWP: 0.51 (95% confidence interval [CI]: 0.41-0.63); CWP-Fe: 0.58 (95% CI: 0.47-0.71), an effect that was observed in all age groups and both sexes after controlling for clustering within households and within individuals over time.

Drinking water and sanitation are two factors of inter-linked inextricably public health especially in the city of Nouakchott where the low availability of these services leads to a multitude of use and hygiene practices involving a complex socio-ecological system with an increased risk of waterborne diseases transmission (diarrhea, cholera, etc.). Thus, this contribution analyzes the impact of socio-ecological system on the development of diarrheal diseases by using socio-environmental and epidemiological data from various sources (national surveys and registries consultation). Overall, the results show that only 25.6% of households have access to drinking water sources while 69.8% of the populations dispose improved latrines. Hence, the weakness in environmental sanitation conditions explains the level of diarrheal morbidity averring 12.8% at the urban level, with an unequal spatial distribution showing less affected communes such as Tevragh Zeina (9.1%) and municipalities more affected like Sebkha (19.1%). The distribution according to the age categories shows that children under 5 years are the most affected with 51.7% followed by people aged over 14 with 34.2%. The correlation analysis between socio-economic, environmental and epidemiological variables reveals a number of significant associations: untreated water consumption and diarrhea (R = 0.429); collection of wastewater and occurrence of diarrhea ; existence of improved latrine and reduction of diarrheal risk (R = 0.402). Therefore, exposure to diarrheal diseases through the prism of water and sanitation is a real public health problem that requires a systemic and integrated approach to improving environmental health.

Full Text Available The study aims to assess the impact of rotavirus vaccine introduction on diarrheal diseases hospitalization and to identify the rotavirus genotypes most prevalent before and after vaccine introduction among children ≤ 5 years of age. Rotarix™ ® rotavirus vaccine is currently licensed for infants in Yemen and was introduced in 2012. The vaccination course consists of two doses. The first dose is administrated at 6 weeks of age and the second dose is completed by 10 weeks. Based on a longitudinal observational study, we assessed the impact of vaccination on rotavirus hospitalization before and after vaccination among children ≤ 5 years of age at the Yemeni-Swedish Hospital (YSH in Taiz, Yemen. Prevaccination covered January 2009–July 2012 during which 2335 fecal samples were collected from children ≤ 5 years old. Postvaccination covered January 2013–December 2014 during which 1114 fecal samples were collected. Rotavirus was detected by Enzyme Linkage Immunosorbent Assay (ELISA. The incidence of rotavirus hospitalization decreased from 43.79% in 2009 to 10.54% in 2014. Hospitalization due to rotavirus diarrhea was reduced by 75.93%. Vaccine coverage increased from 23% in 2012 to 72% in 2014. Also, the results showed that the most predominant genotypes in prevaccination period were G2P[4] (55.0%, followed by G1P[8] (15.0%, while in postvaccination period G1P[8] (31% was the predominant genotype, followed by G9P[8] (27.5%. In conclusion, rotavirus vaccination in Yemen resulted in sharp reduction in diarrheal hospitalization. A successful rotavirus vaccination program in Yemen will rely upon efficient vaccine delivery systems and sustained vaccine efficacy against diverse and evolving rotavirus strains.

Point of use drinking water treatment with the BioSand filter (BSF) allows people to treat their water in the home. The purpose of this research was to document the ability of the Hydraid plastic-housing BSF to reduce diarrheal disease in households who received a BSF in a randomized controlled trial. The trial of the Hydraid plastic-housing BSF was carried out in rural, mountainous communities in Copan, Honduras during April of 2008 to February of 2009. A logistic regression adjusting for clustering showed that the incidence of diarrheal disease in children under 5 years was reduced by approximately 45% (odds ratio = 0.55, 95% confidence interval = 0.28, 1.10) in households that had a BSF compared with those households without a BSF, but this finding fluctuated depending on season and was not statistically significant. Households with a BSF had significantly better drinking water quality regardless of water source or season. PMID:22665593

Full Text Available Three newly discovered viruses have been recently described in diarrheal patients: Cosavirus (CosV and Salivirus (SalV, two picornaviruses, and Bufavirus (BuV, a parvovirus. The detection rate and the role of these viruses remain to be established in acute gastroenteritis (AGE in diarrheal Tunisian infants. From October 2010 through March 2012, stool samples were collected from 203 children <5 years-old suffering from AGE and attending the Children's Hospital in Monastir, Tunisia. All samples were screened for CosV, SalV and BuV as well as for norovirus (NoV and group A rotavirus (RVA by molecular biology. Positive samples for the three screened viruses were also tested for astrovirus, sapovirus, adenovirus, and Aichi virus, then genotyped when technically feasible. During the study period, 11 (5.4% samples were positive for one of the three investigated viruses: 2 (1.0% CosV-A10, 7 (3.5% SalV-A1 and 2 (1.0% BuV-1, whereas 71 (35.0% children were infected with NoV and 50 (24.6% with RVA. No mixed infections involving the three viruses were found, but multiple infections with up to 4 classic enteric viruses were found in all cases. Although these viruses are suspected to be responsible for AGE in children, our data showed that this association was uncertain since all infected children also presented infections with several enteric viruses, suggesting here potential water-borne transmission. Therefore, further studies with large cohorts of healthy and diarrheal children will be needed to evaluate their clinical role in AGE.

Diarrhea remains the most common infectious disease worldwide. Zinc has been studied extensively recently for its potential effect on prevention, control and treatment of acute diarrhoea. This study was designed to correlate the level of zinc with the severity of pediatric diarrhoea estimated by Vesikari Scoring System. The present study included 80 children aged two months to 30 months from those suffering from the acute diarrheal episode and admitted to Pediatric Hospital "Abo El Rish" Cairo University. Serum Zinc level was assessed by a colorimetric method with a spectrophotometer. Zinc deficiency was detected in 45 (56.2%) patient of the studied group Significant negative correlations were found between serum zinc level and severity of dehydration and duration of hospitalization (p Zinc level has an essential role in acute pediatric diarrhoea. Zinc therapy should be considered beside Oral rehydration salts (ORS) to achieve maximum impact on diarrheal diseases; clinical trials are recommended to support the zinc supplementation in developing countries.

Microbial diarrheal diseases are one of the leading causes of child morbidity and mortality in developing countries. This study aimed to identify the main causes of non-bacterial diarrhea in Afghanistan. A total of 699 stools were collected from children aged under 5 years who presented with diarrhea at Indira Gandhi and Kandahar hospitals. Frozen aliquots were preserved for screening against rotavirus, astrovirus, adenovirus, norovirus, Cryptosporidium and Giardia, when bacterial cultures tested negative. Tests were performed at the hospitals after laboratory staff were trained and provided with enzyme-immunoassays and equipment. Results were confirmed at the U.S. Naval Medical Research Unit No. 3, Cairo, Egypt. Of the samples tested, 71.9% (503/699) were infected with one or more pathogens. However, the majority (85.8%; 432/503) showed single infections: rotavirus (72.2%; 329/432), Cryptosporidium (14.1%; 61/432), Giardia (5.1%; 22/432), astrovirus (2.3%; 10/432), adenovirus (1.6%; 7/432) and norovirus (0.7%; 3/432). The remaining 14% (71/503) showed mixed infections of the tested pathogens. Non-bacterial pathogens were identified that could enable health officials to adopt more effective treatment and control measures for diarrhea in Afghanistan.

Congenital diarrheal disorders (CDDs) are a group of inherited enteropathies with a typical onset early in the life. Infants with these disorders have frequently chronic diarrhea of sufficient severity to require parenteral nutrition. For most CDDs the disease-gene is known and molecular analysis may contribute to an unequivocal diagnosis. We review CDDs on the basis of the genetic defect, focusing on the significant contribution of molecular analysis in the complex, multistep diagnostic work-up.

Could arsenic mitigation lead to increased diarrheal disease in Bangladesh? The health risks of As exposure caused by the installation of millions of shallow tubewells in the Bengal Basin are widely known but fecal contamination of groundwater in this densely populated region with poor sanitation has rarely been studied systematically. In order to examine the degree of microbial contamination of groundwater and, specifically, determine whether arsenic mitigation by switching between shallow wells might affect exposure to microbial pathogens, 125 tubewells ranging between 20 and 120 ft in depth and spanning a wide range of As concentrations were monitored monthly for the fecal indicator E. coli across 7 villages of Matlab and Araihazar, Bangladesh. Overall, the fraction of shallow wells with detectable E. coli ranged from 20% during the dry season to 70% during the monsoon. The linear relation observed between the frequency of E. coli detection in well water during the monsoon and population residing within 25 m of a well (pcontamination and population density that might be explained by variations in overlying fecal source strength, coupled with rapid infiltration of surface contaminants into the aquifer. Neither well depth within the 20-120 ft range nor the presence of a concrete platform at the surface had a detectable impact on E. coli levels in well water. PCR analysis of groundwater from 50 wells where E. coli was detected (i.e. >1 CFU/100 mL) indicates that 40% of the wells contained a known pathogen such as Shigella, rotavirus or pathogenic E. coli. Detection of E. coli was on average higher by two-thirds in shallow wells with up to 10 ug/L As compared to shallow wells with >50 ug/L As. This raises the possibility that the most widely applied form of As mitigation, switching to a neighboring household’s low-As well, could result in increased exposure to microbial pathogens. The inverse relation between E. coli detection frequency and groundwater As may

To understand protozoan, viral, and bacterial infections in diarrheal patients, we analyzed positivity and mixed-infection status with 3 protozoans, 4 viruses, and 10 bacteria in hospitalized diarrheal patients during 2004-2006 in the Republic of Korea. A total of 76,652 stool samples were collected from 96 hospitals across the nation. The positivity for protozoa, viruses, and bacteria was 129, 1,759, and 1,797 per 10,000 persons, respectively. Especially, Cryptosporidium parvum was highly mixed-infected with rotavirus among pediatric diarrheal patients (29.5 per 100 C. parvum positive cases), and Entamoeba histolytica was mixed-infected with Clostridium perfringens (10.3 per 100 E. histolytica positive cases) in protozoan-diarrheal patients. Those infected with rotavirus and C. perfringens constituted relatively high proportions among mixed infection cases from January to April. The positivity for rotavirus among viral infection for those aged ≤ 5 years was significantly higher, while C. perfringens among bacterial infection was higher for ≥ 50 years. The information for association of viral and bacterial infections with enteropathogenic protozoa in diarrheal patients may contribute to improvement of care for diarrhea as well as development of control strategies for diarrheal diseases in Korea.

The role of climate forcing in the population dynamics of infectious diseases has typically been revealed via retrospective analyses of incidence records aggregated across space and, in particular, over whole cities. Here, we focus on the transmission dynamics of rotavirus, the main diarrheal disease in infants and young children, within the megacity of Dhaka, Bangladesh. We identify two zones, the densely urbanized core and the more rural periphery, that respond differentially to flooding. Moreover, disease seasonality differs substantially between these regions, spanning variation comparable to the variation from tropical to temperate regions. By combining process-based models with an extensive disease surveillance record, we show that the response to climate forcing is mainly seasonal in the core, where a more endemic transmission resulting from an asymptomatic reservoir facilitates the response to the monsoons. The force of infection in this monsoon peak can be an order of magnitude larger than the force of infection in the more epidemic periphery, which exhibits little or no postmonsoon outbreak in a pattern typical of nearby rural areas. A typically smaller peak during the monsoon season nevertheless shows sensitivity to interannual variability in flooding. High human density in the core is one explanation for enhanced transmission during troughs and an associated seasonal monsoon response in this diarrheal disease, which unlike cholera, has not been widely viewed as climate-sensitive. Spatial demographic, socioeconomic, and environmental heterogeneity can create reservoirs of infection and enhance the sensitivity of disease systems to climate forcing, especially in the populated cities of the developing world.

To explore whether different forms of violence against women were associated with increased incidence rates of diarrhea and respiratory tract infections among infants. A 12-month follow-up study embedded in a food and micronutrient supplementation trial. Rural Bangladesh. Pregnant women and their 3132 live-born children. Maternal exposure to physical, sexual, and emotional violence and level of controlling behavior in the family. Infants' risk of falling ill with diarrheal diseases and respiratory tract infections in relation to mothers' exposure to different forms of violence. Adjusted for household economic conditions, mother's education level, parity, and religion. Fifty percent of the women reported lifetime experience of family violence. Infants of mothers exposed to different forms of family violence had 26% to 37% higher incidence of diarrhea. Any lifetime family violence was positively associated with increased incidence of diarrheal diseases (adjusted rate ratio, 1.20; 95% confidence interval, 1.10-1.30) and lower respiratory tract infections (adjusted rate ratio, 1.31; 95% confidence interval, 1.17-1.46). Further, all forms of family violence were also independently positively associated with infant illness, and the highest incidence rates were found among the daughters of severely physically abused mothers. Family violence against women was positively associated with an increased risk of falling ill with diarrheal and respiratory tract infections during infancy. The present findings add to increasing evidence of the magnitude of public health consequences of violence against women.

Acute malnutrition to be a major health burden in the world, particularly in the developing world. Acute malnutrition is associated with more than one third of the global disease burden for children. Malnourished children are physically, emotionally and intellectually less productive and suffer more from chronic illnesses and disabilities. The nature, magnitude and determinants of acute malnutrition are determined among the general populations; however, there is a lack of evidence in the nomadic communities. A cross-sectional study was conducted to assess the magnitude and factors associated with acute malnutrition among children aged 6-59 months in Hadaleala district, Afar Region. A total of 591 under-five children were included in this study, and subjects were recruited by the multistage cluster sampling technique. Data were collected by a pre-tested questionnaire and a simple anthropometric index so called mid-upper arm circumference (MUAC). The multivariable binary logistic regression analysis was used to identify factors associated with acute malnutrition on the basis of adjusted odds ratio (AOR) with 95% confidence interval (CI) and p malnutrition was 11.8% (95% CI = 9.3, 14.8%). The highest prevalence (50%) of acute malnutrition occurred among children aged between 12.0-23.0 months. Childhood acute malnutrition was associated with the presence of two (AOR = 2.49, p childhood diarrheal disease (AOR = 2.72, p malnutrition among children aged 6-59 months was was higher than the national prevalence. The number of children in each household, drinking water sources, latrine availability, hand washing practice before food preparation and child feeding, childhood diarrheal disease, and child vaccination were identified as factors affecting the childhood acute malnutrition in the nomadic community. Protecting drinking water sources from possible contaminants, improving hand washing practices, utilization of latrine, preventing diarrheal diseases

A study on knowledge, attitude and practice of health care providers in Palembang had been conducted at the end of 1989 and beginning of 1990. Four approaches were carried out: (1) by recording the help obtained by cases who consulted researchers for further help for the same diarrheal diseases (DD) episode, (2) by studying the medical records of DD cases admitted to three hospitals, (3) by studying prescriptions dispensed by three pharmacies and (4) by focus group discussions. The findings were analysed to evaluate the achievement of the Indonesian Diarrheal Diseases Control Program (CDD). ORT, avoiding antimotility drugs and appropriated feeding have been accepted and practiced by the providers in Palembang. The target of promotion now is to support the acquisition of these behaviours to be implemented as a routine habit of the providers and as a part of the ongoing system of health care delivery system. Specifically the danger of loperamide promotion to the policy on antimotility must be stressed. Rapid iv rehydration and avoiding surface precipitating agents have been accepted, but are not practiced consistently yet due to practical considerations. It seems that there is no impact at all of CDD towards the rate of antibiotic therapy in DD. Besides intensifying the campaign, enforcing group pressure, may be we have to elaborate more the perception of health care provider as a practitioner, and conforming the strategy of the CDD campaign towards the findings. Health education had not been practiced effectively yet. Morale and value system of the providers are important for the success of this program. In general the medical-technic aspect of the CDD has been accepted by the providers, but there is still a lot to do in communicating them to be adopted as an effective behaviour.

Age specific fast breathing in under-five diarrheal children in an urban hospital: Acidosis or pneumonia?

Directory of Open Access Journals (Sweden)

Sharika Nuzhat

Full Text Available Children with diarrhea often present with fast breathing due to metabolic acidosis from dehydration. On the other hand, age specific fast breathing is the cornerstone for the diagnosis of pneumonia following classification of pneumonia recommended by the World Health Organization (WHO. Correction of metabolic acidosis by rehydrating the diarrheal children requires time, which delays early initiation of appropriate antimicrobials for pneumonia and thereby increases the risk of deaths. We need to further investigate the simple clinical features other than fast breathing which might help us in earliest diagnosis of pneumonia in children with diarrhea Thus, the objective of our study was to identify other contributing clinical features that may independently help for early diagnosis of pneumonia in diarrheal children who present with age specific fast breathing.This was an unmatched case-control study. Diarrheal children aged 0-59 months, admitted to Dhaka Hospital of the International Centre for Diarrheal Disease Research, Bangladesh (icddr,b during January 2014 to December 2014 having age specific fast breathing (11-59 months ≥40 breaths/min were studied. The study children with clinical and radiological pneumonia constituted the cases (n = 276 and those without pneumonia constituted the controls (n = 446. Comparison of clinical features and outcomes between the cases and the controls was made.The distribution of acidosis among the cases and the controls was comparable (35% vs. 41%, p = 0.12. The cases had proportionately higher deaths compared to the controls, however, the difference was not statistically significant (3% vs. 1%; p = 0.23. In logistic regression analysis after adjusting for potential confounders, the cases were independently associated with cough (OR = 62.19, 95% CI = 27.79-139.19; p<0.01 and chest wall indrawing (OR = 31.05, 95%CI = 13.43-71.82; p<0.01 and less often had severe acute malnutrition (OR = 0.33, 95%CI = 0

In China, waterborne outbreaks of infectious diarrheal disease mainly occur in schools, and contaminated well water is a common source of pathogens. The objective of this review was to present the attack rates, durations of outbreak, pathogens of infectious diarrheal disease, and sanitary conditions of wells in primary and secondary schools in China, and to analyze risk factors and susceptibility of school children. Relevant articles and reports were identified by searching PubMed, Web of Science, China National Knowledge Infrastructure, China Information System for Disease Control and Prevention, and the Chinese Field Epidemiology Training Program. Essential information, including urban/rural areas, school types, attack rates, pathogens, durations of outbreak, report intervals, and interventions were extracted from the eligible articles. Wilcoxon signed-rank test, Kruskal-Wallis H test, and Spearman correlation test were conducted in statistical analyses. Sex- and age-specific attack rate ratios were calculated as pooled effect sizes. We screened 2188 articles and retrieved data of 85 outbreaks from 1987 to 2014. Attack rates of outbreaks in rural areas (median, 12.63 cases/100 persons) and in primary schools (median, 14.54 cases/100 persons) were higher than those in urban areas (median, 5.62 cases/100 persons) and in secondary schools (median, 8.74 cases/100 persons) (P = 0.004 and P = 0.013, respectively). Shigella, pathogenic Escherichia coli, and norovirus were the most common pathogens. Boys tended toward higher attack rates than girls (sex-specific attack rate ratio, 1.13; 95% CI, 1.00-1.29, P = 0.05). Unsanitary conditions of water wells were reported frequently, and unhealthy behavior habits were common in students. School children were susceptible to waterborne disease in China. Chinese government should make efforts to improve access to safe water in schools. Health education promotion and conscientiousness of school leaders and teachers should be

Increase in diarrheal disease associated with arsenic mitigation in Bangladesh.

Full Text Available Millions of households throughout Bangladesh have been exposed to high levels of arsenic (As causing various deadly diseases by drinking groundwater from shallow tubewells for the past 30 years. Well testing has been the most effective form of mitigation because it has induced massive switching from tubewells that are high (>50 µg/L in As to neighboring wells that are low in As. A recent study has shown, however, that shallow low-As wells are more likely to be contaminated with the fecal indicator E. coli than shallow high-As wells, suggesting that well switching might lead to an increase in diarrheal disease.Approximately 60,000 episodes of childhood diarrhea were collected monthly by community health workers between 2000 and 2006 in 142 villages of Matlab, Bangladesh. In this cross-sectional study, associations between childhood diarrhea and As levels in tubewell water were evaluated using logistic regression models.Adjusting for wealth, population density, and flood control by multivariate logistic regression, the model indicates an 11% (95% confidence intervals (CIs of 4-19% increase in the likelihood of diarrhea in children drinking from shallow wells with 10-50 µg/L As compared to shallow wells with >50 µg/L As. The same model indicates a 26% (95%CI: 9-42% increase in diarrhea for children drinking from shallow wells with ≤10 µg/L As compared to shallow wells with >50 µg/L As.Children drinking water from shallow low As wells had a higher prevalence of diarrhea than children drinking water from high As wells. This suggests that the health benefits of reducing As exposure may to some extent be countered by an increase in childhood diarrhea.

From May through October 1980, the "Strengthening Rural Health Delivery" project (SRHD) under the Rural Health Department of the Ministry of Health of Egypt had conducted an investigation into prevention of child mortality from diarrheal disease through testing various modules of Oral Rehydration Therapy delivery mechanisms. In a six-cell design counting a total of almost 29,000 children, ORT was provided both as hypotonic sucrose/salt solution prepared and administered by mothers and normotonic, balanced electrolyte solution in the hands of both mothers and health care providers and the effects on child mortality during the peak season of diarrheal incidence were measured. In addition, utilization and effects of ORT when made readily available through commercial channels was similarly examined. A cost-benefit analysis was performed on the cost of the services as well as on the outcome for each of five study cells using the sixth, the control, as reference. Results showed that early rehydration with a sucrose/salt solution in the hands of mothers, backed by balanced oral rehydration solution in the hands of health care providers proved the most cost-effective means of reducing diarrhea-specific mortality as well as being as safe as prepackaged commercial preparations.

Children with acute and chronic malnutrition are at increased risk of morbidity and mortality following a diarrheal episode. To compare diarrheal disease severity and pathogen prevalence among children with and without acute and chronic malnutrition, we conducted a cross-sectional study of human immunodeficiency virus-uninfected Kenyan children aged 6-59 months, who presented with acute diarrhea. Children underwent clinical and anthropometric assessments and provided stool for bacterial and protozoal pathogen detection. Clinical and microbiological features were compared using log binomial regression among children with and without wasting (mid-upper arm circumference ≤ 125 mm) or stunting (height-for-age z score ≤ -2).

Diarrhea remains one of the major causes of death in Bangladesh. We studied diarrheal disease risk and healthcare seeking behavior among populations at high risk for diarrhea in Dhaka, Bangladesh. Data were obtained from a cross-sectional survey conducted during April and September 2010. The prevalence of diarrhea was calculated by age-group and sex. A generalized estimating equation with logit link function was used to predict diarrheal disease risk and seeking care from a professional healthcare provider. Of 316,766 individuals, 10% were young children (Bangladesh. Dissemination of information on health education, increasing the supply of skilled healthcare providers, and low-cost and quality healthcare services may encourage more people to seek care from professional healthcare providers, thus may help reduce child mortality in the country. Further studies are warranted to validate the results. PMID:26121650

Full Text Available Abstract Background Diarrheal diseases are the major causes of morbidity and mortality in developing world. Understanding the etiologic agents of diarrheal diseases and their association with socio-demographic characteristics of patients would help to design better preventive measures. Thus, this study was aimed to determine the prevalence of intestinal parasites and enteropathogenic bacteria in diarrheic patients. Methods A cross-sectional study involving 384 consecutive diarrheal patients who visited Gondar teaching hospital, Gondar, Ethiopia from October 2006 to March 2007 was conducted. Stool specimens were collected and examined for intestinal parasites and enteropathogenic bacteria following standard parasitological and microbiological procedures. Results Intestinal parasites were diagnosed in 36.5% of the patients. The most frequently encountered protozoan parasite was Entamoeba histolytica/dispar (7.3% followed by Giardia lamblia (5.0%, Cryptosporidium parvum (1.8% and Isospora belli (1.3%. The dominant helminthic parasite identified was Ascaris lumbricoides (5.5% followed by Strongyloides stercoralis and Schistosoma mansoni (3.1% each, hookworm infection (1.8%, and Hymenolepis species (1.3%. Multiple infections of intestinal parasites were also observed in 6.3% of the patients. Among the enteropathogenic bacteria Shigella and Salmonella species were isolated from 15.6% and 1.6%, respectively, of the patients. Escherichia coli O57:H7 was not found in any of the stool samples tested. Eighty eight percent and 83.3% of the Shigella and Salmonella isolates were resistant to one or more commonly used antibiotics, respectively. Intestinal parasitosis was higher in patients who live in rural area, in patients who were washing their hands after visiting toilet either irregularly with soap and without soap or not at all, in patients who used well and spring water for household consumption, and in patients who had nausea (P P Conclusions The high

In endemic settings, Helicobacter pylori infection can occur shortly after birth and may be associated with a reduction in childhood growth. This study investigated what factors promote earlier age of first H. pylori infection and evaluated the role of H. pylori infection in infancy (6-11 months) versus early childhood (12-23 months) on height. We included 183 children near birth from a peri-urban shanty town outside of Lima, Peru. Field-workers collected data on socioeconomic status (SES), daily diarrheal and breast-feeding history, antibiotic use, anthropometrics, and H. pylori status via carbon 13-labeled urea breath test up to 24 months after birth. We used a proportional hazards model to assess risk factors for earlier age at first detected infection and linear mixed-effects models to evaluate the association of first detected H. pylori infection during infancy on attained height. One hundred and forty (77%) were infected before 12 months of age. Lower SES was associated with earlier age at first detected H. pylori infection (low vs middle-to-high SES Hazard ratio (HR) 1.59, 95% CI 1.16, 2.19; p = .004), and greater exclusive breast-feeding was associated with reduced likelihood (HR 0.63, 95% CI 0.40, 0.98, p = .04). H. pylori infection in infancy was not independently associated with growth deficits (p = .58). However, children who had their first detected H. pylori infection in infancy (6-11 months) versus early childhood (12-23 months) and who had an average number of diarrhea episodes per year (3.4) were significantly shorter at 24 months (-0.37 cm, 95% CI, -0.60, -0.15 cm; p = .001). Lower SES was associated with a higher risk of first detected H. pylori infection during infancy, which in turn augmented the adverse association of diarrheal disease on linear growth. © 2014 John Wiley & Sons Ltd.

Anti-diarrheal effects of diosmectite in the treatment of acute diarrhea in children: a review.

Science.gov (United States)

Dupont, Christophe; Vernisse, Bernard

2009-01-01

Acute diarrhea caused by an infectious organism is highly prevalent, particularly in developing countries, and is usually self-limiting. The condition is a major contributor to the global disease burden and is associated with a significant economic cost. The disease is common in children aged Diarrhea almost always occurs by one or more of four mechanisms: disruption of osmotic forces in the intestine; disruption of normal secretory processes; disruption of epithelial cells or the epithelial tight junctions; or motility disorders. Oral rehydration therapy (ORT) is central to the management of acute diarrhea, and is sufficient to prevent complications due to dehydration in most patients while the disease runs its course. However, ORT has no effect on the duration of the disease or frequency of bowel motions, and any agent that could meet these needs would therefore be a useful addition to ORT. Diosmectite is a natural aluminomagnesium silicate clay with a lamellar, non-fibrous crystalline structure that gives it strong adsorbent properties. Its mechanisms of action are not yet fully understood, but are probably multiple. Diosmectite reduces inflammation, modifies mucus rheologic properties, inhibits mucolysis, and adsorbs bacteria, bacterial enterotoxins, viruses and other potentially diarrheogenic substances. A number of studies have shown that diosmectite reduces the duration of diarrhea and decreases the frequency of bowel motions after 2 days of treatment in children with mild-to-moderate acute diarrhea. Two recent trials have indicated a reduction in stool output with diosmectite. Because of its very favorable safety profile, with no serious adverse effects, diosmectite is frequently used, mainly in European countries but also in Asia and Africa. Diosmectite should be used as an adjunct, not an alternative, to ORT and, when needed, to antibacterial therapy.

To determine the effectiveness of ceramic filters in reducing diarrhea, we conducted a randomized controlled trial in Zimbabwe and South Africa, in which 61 of 115 households received ceramic filters. Incidence of non-bloody and bloody diarrhea was recorded daily over 6 months using pictorial diaries for children 24-36 months of age. Poisson regression was used to compare incidence rates in intervention and control households. Adjusted for source quality, intervention household drinking water showed reduced Escherichia coli counts (relative risk, 0.67; 95% CI, 0.50-0.89). Zero E. coli were obtained for drinking water in 56.9% of intervention households. The incidence rate ratio for bloody diarrhea was 0.20 (95% CI, 0.09-0.43; P filter users. The results suggest that ceramic filters are effective in reducing diarrheal disease incidence.

Children with diarrhea often present with fast breathing due to metabolic acidosis from dehydration. On the other hand, age specific fast breathing is the cornerstone for the diagnosis of pneumonia following classification of pneumonia recommended by the World Health Organization (WHO). Correction of metabolic acidosis by rehydrating the diarrheal children requires time, which delays early initiation of appropriate antimicrobials for pneumonia and thereby increases the risk of deaths. We need to further investigate the simple clinical features other than fast breathing which might help us in earliest diagnosis of pneumonia in children with diarrhea Thus, the objective of our study was to identify other contributing clinical features that may independently help for early diagnosis of pneumonia in diarrheal children who present with age specific fast breathing. This was an unmatched case-control study. Diarrheal children aged 0-59 months, admitted to Dhaka Hospital of the International Centre for Diarrheal Disease Research, Bangladesh (icddr,b) during January 2014 to December 2014 having age specific fast breathing (11-59 months ≥40 breaths/min) were studied. The study children with clinical and radiological pneumonia constituted the cases (n = 276) and those without pneumonia constituted the controls (n = 446). Comparison of clinical features and outcomes between the cases and the controls was made. The distribution of acidosis among the cases and the controls was comparable (35% vs. 41%, p = 0.12). The cases had proportionately higher deaths compared to the controls, however, the difference was not statistically significant (3% vs. 1%; p = 0.23). In logistic regression analysis after adjusting for potential confounders, the cases were independently associated with cough (OR = 62.19, 95% CI = 27.79-139.19; ppneumonia. The results underscore the importance of early identification of these simple clinical features that may help to minimize potential delay due to

Hydroclimatic drivers, Water-borne Diseases, and Population Vulnerability in Bengal Delta

Water-borne diarrheal disease outbreaks in the Bengal Delta region, such as cholera, rotavirus, and dysentery, show distinct seasonal peaks and spatial signatures in their origin and progression. However, the mechanisms behind these seasonal phenomena, especially the role of regional climatic and hydrologic processes behind the disease outbreaks, are not fully understood. Overall diarrheal disease prevalence and the population vulnerability to transmission mechanisms thus remain severely underestimated. Recent findings suggest that diarrheal incidence in the spring is strongly associated with scarcity of freshwater flow volumes, while the abundance of water in monsoon show strong positive correlation with autumn diarrheal burden. The role of large-scale ocean-atmospheric processes that tend to modulate meteorological, hydrological, and environmental conditions over large regions and the effects on the ecological states conducive to the vectors and triggers of diarrheal outbreaks over large geographic regions are not well understood. We take a large scale approach to conduct detailed diagnostic analyses of a range of climate, hydrological, and ecosystem variables to investigate their links to outbreaks, occurrence, and transmission of the most prevalent water-borne diarrheal diseases. We employ satellite remote sensing data products to track coastal ecosystems and plankton processes related to cholera outbreaks. In addition, we investigate the effect of large scale hydroclimatic extremes (e.g., droughts and floods, El Nino) to identify how diarrheal transmission and epidemic outbreaks are most likely to respond to shifts in climatic, hydrologic, and ecological changes over coming decades. We argue that controlling diarrheal disease burden will require an integrated predictive surveillance approach - a combination of prediction and prevention - with recent advances in climate-based predictive capabilities and demonstrated successes in primary and tertiary prevention

A full term, previously normal 2 1/2-month-old black boy was transferred to our hospital from an outlying facility on hospital day 5 for failure to thrive. Three weeks before transfer, the infant was hospitalized for a diarrheal illness with fever. The baby received 3 days of ceftriaxone empirically and was discharged home after the sepsis evaluation was negative. Mild diarrhea and steady weight loss continued and the baby was readmitted. Blood culture done on admission grew Flavobacterium meningosepticum, an organism previously described as an uncommon cause of sepsis in neonates and immunocompromised individuals. As it is water-borne, it has been associated with infection via contaminated water. This organism is usually resistant to antibiotics commonly used for empiric treatment. To our knowledge, this is the first reported case of Flavobacterium bacteremia associated with a prodromal and concurrent diarrheal illness.

Effects of antibiotic resistance (AR) and microbiota shifts on Campylobacter jejuni-mediated diseases.

Brooks, Phillip T; Mansfield, Linda S

2017-12-01

Campylobacter jejuni is an important zoonotic pathogen recently designated a serious antimicrobial resistant (AR) threat. While most patients with C. jejuni experience hemorrhagic colitis, serious autoimmune conditions can follow including inflammatory bowel disease (IBD) and the acute neuropathy Guillain Barré Syndrome (GBS). This review examines inter-relationships among factors mediating C. jejuni diarrheal versus autoimmune disease especially AR C. jejuni and microbiome shifts. Because both susceptible and AR C. jejuni are acquired from animals or their products, we consider their role in harboring strains. Inter-relationships among factors mediating C. jejuni colonization, diarrheal and autoimmune disease include C. jejuni virulence factors and AR, the enteric microbiome, and host responses. Because AR C. jejuni have been suggested to affect the severity of disease, length of infections and propensity to develop GBS, it is important to understand how these interactions occur when strains are under selection by antimicrobials. More work is needed to elucidate host-pathogen interactions of AR C. jejuni compared with susceptible strains and how AR C. jejuni are maintained and evolve in animal reservoirs and the extent of transmission to humans. These knowledge gaps impair the development of effective strategies to prevent the emergence of AR C. jejuni in reservoir species and human populations.

Electrophysiological Studies into the Safety of the Anti-diarrheal Drug Clotrimazole during Oral Rehydration Therapy.

Full Text Available Morbidity and mortality from acute diarrheal disease remains high, particularly in developing countries and in cases of natural or man-made disasters. Previous work has shown that the small molecule clotrimazole inhibits intestinal Cl- secretion by blocking both cyclic nucleotide- and Ca(2+-gated K(+ channels, implicating its use in the treatment of diarrhea of diverse etiologies. Clotrimazole, however, might also inhibit transporters that mediate the inwardly directed electrochemical potential for Na(+-dependent solute absorption, which would undermine its clinical application. Here we test this possibility by examining the effects of clotrimazole on Na(+-coupled glucose uptake.Short-circuit currents (Isc following administration of glucose and secretagogues were studied in clotrimazole-treated jejunal sections of mouse intestine mounted in Ussing chambers.Treatment of small intestinal tissue with clotrimazole inhibited the Cl- secretory currents that resulted from challenge with the cAMP-agonist vasoactive intestinal peptide (VIP or Ca(2+-agonist carbachol in a dose-dependent fashion. A dose of 30 μM was effective in significantly reducing the Isc response to VIP and carbachol by 50% and 72%, respectively. At this dose, uptake of glucose was only marginally affected (decreased by 14%, p = 0.37. There was no measurable effect on SGLT1-mediated sugar transport, as uptake of SGLT1-restricted 3-O-methyl glucose was equivalent between clotrimazole-treated and untreated tissue (98% vs. 100%, p = 0.90.Treatment of intestinal tissue with clotrimazole significantly reduced secretory responses caused by both cAMP- and Ca(2+-dependent agonists as expected, but did not affect Na(+-coupled glucose absorption. Clotrimazole could thus be used in conjunction with oral rehydration solution as a low-cost, auxiliary treatment of acute secretory diarrheas.

Diarrheal disease continues to be an important cause of morbidity and mortality among young children in developing countries including Ethiopia. Globally, intestinal parasite, Shigella and Salmonella species remain major contributors to acute enteric infections. The study was aimed at determining the frequency of intestinal parasite, Shigella and Salmonella species identified from diarrheic children at Jimma Health Centre, Jimma south west Ethiopia. A health institution based cross sectional study was conducted from March to November 2012. A structured questionnaire was used for collection of data on socio- demographic characteristics. Parasite and bacteria identification as well as susceptibility testing was done using standard parasitological and bacteriological procedures. A total of 260 diarrheal children were included in the study. A total of 129 (49.6%) samples were positive for intestinal parasite, Shigella and Salmonella species. Of these, 107 (41.1%), 6 (2.3%) and 16 (6.2%) samples were positive for intestinal parasite, Shigella and Salmonella species respectively. The dominant isolated parasite was G. lamblia with prevalence of 13.5% followed by A. lumbricoides (11.5%). The least identified parasites were Schistosoma mansoni and Taenia species accounting 0.4% each. Multiple parasitic infections were observed in 19 (7.3%) patients. Shigella species showed hundred percent resistances to ampicillin, amoxacillin, and cotrimoxazole. All Salmonella isolates were resistant against amoxicillin. All Shigella and Salmonella species were susceptible to ceftriaxone, ciprofloxacin and gentamycin. The presence of reasonably high amount of intestinal parasite and Salmonella and Shigella species that are drug resistance to the commonly prescribed drugs is a treat to the children and community at large. Therefore, measures including health education, improvement of safe water supply, sanitation facilities and continuous monitoring of microbiological and antimicrobial

Full Text Available Acute hemorrhagic disease is an important problem in medicine that can be seen in many countries, especially those in tropical world. There are many causes of acute hemorrhagic disease and the viral infection seems to be the common cause. The well-known infection is dengue, however, there are many new identified viruses that can cause acute hemorrhagic diseases. In this specific short review, the authors present and discuss on those new virus diseases that present as “acute hemorrhagic fever”.

Full Text Available Salmonella enterica serovar Weltevreden (S. Weltevreden is an emerging cause of diarrheal and invasive disease in humans residing in tropical regions. Despite the regional and international emergence of this Salmonella serovar, relatively little is known about its genetic diversity, genomics or virulence potential in model systems. Here we used whole genome sequencing and bioinformatics analyses to define the phylogenetic structure of a diverse global selection of S. Weltevreden. Phylogenetic analysis of more than 100 isolates demonstrated that the population of S. Weltevreden can be segregated into two main phylogenetic clusters, one associated predominantly with continental Southeast Asia and the other more internationally dispersed. Subcluster analysis suggested the local evolution of S. Weltevreden within specific geographical regions. Four of the isolates were sequenced using long read sequencing to produce high quality reference genomes. Phenotypic analysis in Hep-2 cells and in a murine infection model indicated that S. Weltevreden were significantly attenuated in these models compared to the classical S. Typhimurium reference strain SL1344. Our work outlines novel insights into this important emerging pathogen and provides a baseline understanding for future research studies.

Full Text Available Presentamos una etnoepidemiología de las enfermedades diarreicas en 21 pueblos de la costa norte del Ecuador, zona en la cual hay muchos cambios sociales y ambientales desde 2001 por la presencia de una nueva carretera. Con percepciones de que la misma naturaleza está cambiando, vienen cambios en interpretaciones de lo que es salud y enfermedad, que presentamos en forma de una taxonomía de males diarreicos. Ante la fuerte incidencia de las enfermedades diarreicas, existen concepciones alternativas a la biomedicina en cuanto a sus causas, síntomas y tratamientos. Hay superposiciones entre sistemas no-biomédicas y biomédicos, en donde hay mezclas de coexistencia y resistencia. Reconocer esto es entender una serie de desafíos para el sistema de salud oficial, incluyendo el uso indiscriminado de antibióticos, el no uso de servicios de salud para algunos males, y relaciones percibidas entre contaminación ambiental y la eficacia de las medicinas moderna y tradicional.The authors present an ethnoepidemiological study of diarrheal illnesses in 21 communities on the northern coast of Ecuador, where numerous social and environmental changes have taken place since 2001 due to a new highway. As communities realize that nature itself is changing, changes occur in their interpretations of health and disease, which the authors present through a taxonomic classification of diarrheal illnesses. Given the high incidence of diarrheal diseases, alternative concepts have emerged (as compared to those of biomedicine in relation to causes, symptoms, and treatments. The non-biomedical and biomedical systems overlap, with mixtures of coexistence and resistance. Recognizing this reality means understanding a series of challenges for the official health system, including the indiscriminate use of antibiotics, non-use of health services for some diseases, and perceived relations between environmental contamination and the efficacy of modern and traditional

Patients with unstable angina or myocardial infarction are at risk of acute kidney injury, which may be aggravated by the iodine-containing contrast agent used during coronary angiography; however, the relationship between these two conditions remains unclear. The current study investigated the relationship between acute kidney injury and coronary heart disease prior to coronary angiography. All patients were evaluated after undergoing coronary angiography in the cardiac catheterization laboratory of the Vinzentius Hospital in Landau, Germany, in 2011. The study group included patients with both acute coronary heart disease and acute kidney injury (as defined according to the classification of the Acute Kidney Injury Group); the control group included patients without acute coronary heart disease. Serum creatinine profiles were evaluated in all patients, as were a variety of demographic and health characteristics. Of the 303 patients examined, 201 (66.34%) had coronary artery disease. Of these, 38 (18.91%) also had both acute kidney injury and acute coronary heart disease prior to and after coronary angiography, and of which in turn 34 (16.91%) had both acute kidney injury and acute coronary heart disease only prior to the coronary angiography. However, the occurrence of acute kidney injury was not significantly related to the presence of coronary heart disease (P = 0.95, Chi-square test). The results of this study indicate that acute kidney injury is not linked to acute coronary heart disease. However, physicians should be aware that many coronary heart patients may develop kidney injury while hospitalized for angiography.

Each year 2.5 billion cases of diarrheal disease are reported in children under five years, and over 1,000 die. Country characteristics could play a role on this situation. We explored associations between country characteristics and diarrheal disease in children under 5 years of age, adjusting by child, mother and household attributes in developing countries. This study included 348,706 children from 40 nations. We conducted a multilevel analysis of data from the Demographic and Health Surveys and the World Bank. The prevalence of acute diarrhea was 14 %. Country inequalities (OR = 1.335; 95 % CI 1.117-1.663) and country's low income (OR = 1.488; 95 % CI 1.024-2.163) were associated with diarrhea, and these country characteristics changed the associations of well-known determinants of diarrhea. Specifically, living in poor countries strengthens the association of poor household wealth and mother's lack of education with the disease. Other factors associated with diarrhea were female sex of the child (OR = 0.922; 95 % CI 0.900-0.944), age of the child (OR = 0.978; 95 % CI 0.978-0.979), immunization status (OR = 0.821; 95 % CI 0.799-0.843), normal birthweight (OR = 0.879; 95 % CI 0.834-0.926), maternal age (OR = 0.987; 95 % CI 0.985-0.989), lack of maternal education (OR = 1.416; 95 % CI 1.283-1.564), working status of the mother (OR = 1.136; 95 % CI 1.106-1.167), planned pregnancy (OR = 0.774; 95 % CI 0.753-0.795), a nuclear family structure (OR = 0.949; 95 % CI 0.923-0.975), and household wealth (OR = 0.948; 95 % CI 0.921-0.977). Inequalities and lack of resources at the country level in developing countries -but not health expenditure- were associated with acute diarrhea, independently of child, family and household features. The broad environment considerably modifies well-known social determinants of acute diarrhea and public health campaigns designed to target diarrhea should consider macro characteristics of the

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.

Natural disasters may lead to infectious disease outbreaks when they result in substantial population displacement and exacerbate synergic risk factors (change in the environment, in human conditions and in the vulnerability to existing pathogens) for disease transmission. We reviewed risk factors and potential infectious diseases resulting from prolonged secondary effects of major natural disasters that occurred from 2000 to 2011. Natural disasters including floods, tsunamis, earthquakes, tropical cyclones (e.g., hurricanes and typhoons) and tornadoes have been secondarily described with the following infectious diseases including diarrheal diseases, acute respiratory infections, malaria, leptospirosis, measles, dengue fever, viral hepatitis, typhoid fever, meningitis, as well as tetanus and cutaneous mucormycosis. Risk assessment is essential in post-disaster situations and the rapid implementation of control measures through re-establishment and improvement of primary healthcare delivery should be given high priority, especially in the absence of pre-disaster surveillance data.

Full Text Available BACKGROUND: Clinical signs of pneumonia are often veiled in under-five diarrheal children presenting with hypokalemia, making clinical diagnosis of pneumonia very difficult in such population. However, there is no published report that describes the influences of hypokalemia on the clinical signs of pneumonia in diarrheal children. Our objective was to assess the influences of hypokalemia, and their outcome in such children. METHODS: We prospectively enrolled all under-five diarrheal children (n = 180 admitted to the Special Care Ward of the Dhaka Hospital of icddr,b from September-December 2007 with radiological pneumonia who also had their serum potassium estimated. We compared the clinical features and outcome of the diarrheal children having pneumonia with (cases = 55 and without hypokalemia (controls = 125. RESULTS: The case-fatality among the cases was 2 times higher compared to the controls, but the difference was not statistically significant (p = 0.202. In logistic regression analysis, after adjusting for potential confounders such as age of the patient, clinical dehydration, severe wasting, abnormally sleepy, lower chest wall in-drawing, nasal flaring and inability to drink on admission, under-five diarrheal children with pneumonia who presented with nutritional edema had 3 times more risk to have hypokalemia compared to those without nutritional edema (OR = 2.76, 95% CI = 1.01-7.51 and these hypokalemic children were 64% less likely to present with fast breathing (OR = 0.36, 95% CI = 0.17-0.74. CONCLUSION AND SIGNIFICANCE: The results of our analysis are simple but may have great public health implications and underscore the importance of diligent assessment for pneumonia in under-five diarrheal children having risk of hypokalemia as in children with nutritional edema even in absence of fast breathing, a useful sign of pneumonia. This may help for early initiation of first dose of parental antibiotics

Full Text Available A series of studies have shown that the heavy burdens of diarrheal diseases in the first 2 formative years of life in children living in urban shanty towns have negative effects on physical and cognitive development lasting into later childhood. We have shown that APOE4 is relatively common in shanty town children living in Brazil (13.4% and suggest that APOE4 has a protective role in cognitive development as well as weight-for-height in children with heavy burdens of diarrhea in early childhood (64/123; 52%, despite being a marker for cognitive decline with Alzheimer’s and cardiovascular diseases later in life. APOE2 frequency was higher among children with heaviest diarrhea burdens during the first 2 years of life, as detected by PCR using the restriction fragment length polymorphism method, raising the possibility that ApoE-cholesterol balance might be critical for growth and cognitive development under the stress of heavy diarrhea burdens and when an enriched fat diet is insufficient. These findings provide a potential explanation for the survival advantage in evolution of genes, which might raise cholesterol levels during heavy stress of diarrhea burdens and malnutrition early in life.

Diarrhea is one of the most common clinical symptoms reported in companion animal clinics. Dog circovirus (DogCV) is a new mammalian circovirus that is considered to be a cause of alimentary syndromes such as diarrhea, vomiting and hemorrhagic enteritis. DogCV has previously only been identified in the United States, Italy, Germany (GeneBank accession number: KF887949) and China (GeneBank accession number: KT946839). Therefore, the aims of this study were to determine the prevalence of DogCV in Taiwan and to explore the correlation between diarrhea and DogCV infection. Clinical specimens were collected between 2012 and 2014 from 207 dogs suffering from diarrhea and 160 healthy dogs. In this study, we developed a sensitive and specific SYBR Green-based real-time PCR assays to detected DogCV in naturally infected animals. Of the analyzed fecal samples from diarrheal dogs and health dogs, 58 (28.0 %) and 19 (11.9 %), respectively, were DogCV positive. The difference in DogCV prevalence was highly significant (P = 0.0002755) in diarrheal dogs. This is the first study to reveal that DogCV is currently circulating in domestic dogs in Taiwan and to demonstrate its high detection rate in dogs with diarrhea.

Full Text Available Despite substantial interventions in the understanding and case management of acute gastroenteritis, diarrheal diseases are still responsible for a notable amount of childhood deaths. Although the rotavirus is known to cause a considerable burden of pediatric diarrheal cases, the roles of other viruses remain undefined for the Pakistani population. This study was based on tertiary care hospital surveillance, from January 2009 to December 2010, including the detection of rotavirus, norovirus, astrovirus, and human parechovirus in children under the age of five using serological or molecular assays. Rotavirus, human parechovirus, norovirus, and astrovirus were detected in 66%, 21%, 19.5%, and 8.5% subjects, respectively. Human parechovirus genotypes, determined through analysis of VP1 gene sequences, showed a great diversity among co-circulating strains. Eighty percent of hospitalized children had dual or multiple viral infections, while 98% parechovirus positive cases were co-infected with rotavirus. The remarkable diversity of viruses associated with the childhood diarrhea in Pakistan calls for large-scale epidemiological surveys, coupled with case control studies, to ascertain their role in clinical manifestations. In addition, these findings also highlight the need for the implementation of up-to-date health interventions, such as the inclusion of a rotavirus vaccine in routine immunization programs for the improvement of quality in child health care.

Hydrological Regime and Water Shortage as Drivers of the Seasonal Incidence of Diarrheal Diseases in a Tropical Montane Environment.

Full Text Available The global burden of diarrhea is a leading cause of morbidity and mortality worldwide. In montane areas of South-East Asia such as northern Laos, recent changes in land use have induced increased runoff, soil erosion and in-stream suspended sediment loads, and potential pathogen dissemination. To our knowledge, few studies have related diarrhea incidences to catchment scale hydrological factors such as river discharge, and loads of suspended sediment and of Fecal Indicator Bacteria (FIB such as Escherichia coli, together with sociological factors such as hygiene practices. We hypothesized that climate factors combined with human behavior control diarrhea incidence, either because higher rainfall, leading to higher stream discharges, suspended sediment loads and FIB counts, are associated with higher numbers of reported diarrhea cases during the rainy season, or because water shortage leads to the use of less safe water sources during the dry season. Using E. coli as a FIB, the objectives of this study were thus (1 to characterize the epidemiological dynamics of diarrhea in Northern Laos, and (2 to identify which hydro-meteorological and sociological risk factors were associated with diarrhea epidemics.Considering two unconnected river catchments of 22 and 7,448 km2, respectively, we conducted a retrospective time series analysis of meteorological variables (rainfall, air temperature, hydrological variables (discharge, suspended sediments, FIB counts, water temperature, and the number of diarrheal disease cases reported at 6 health centers located in the 5 southern districts of the Luang Prabang Province, Lao PDR. We also examined the socio-demographic factors potentially affecting vulnerability to the effect of the climate factors, such as drinking water sources, hygiene habits, and recreational water exposure.Using thus a mixed methods approach, we found E. coli to be present all year long (100-1,000 Most Probable Number or MPN 100 mL-1

Over past two decades there has been significant improvement in medical field in elucidating the underlying pathophysiology and genetics of Addison's disease. Adrenal insufficiency (Addison's disease) is a rare disease with an incidence of 0.8/100,000 cases. The diagnosis may be delayed if the clinical presentation mimics a gastrointestinal disorder or psychiatric illness. We report a case of Addison's disease presenting as acute pain in abdomen mimicking clinical presentation of acute pancreatitis.

Diarrhea, pneumonia, and infectious disease mortality in children aged 5 to 14 years in India.

Full Text Available Little is known about the causes of death in children in India after age five years. The objective of this study is to provide the first ever direct national and sub-national estimates of infectious disease mortality in Indian children aged 5 to 14 years.A verbal autopsy based assessment of 3 855 deaths is children aged 5 to 14 years from a nationally representative survey of deaths occurring in 2001-03 in 1.1 million homes in India.Infectious diseases accounted for 58% of all deaths among children aged 5 to 14 years. About 18% of deaths were due to diarrheal diseases, 10% due to pneumonia, 8% due to central nervous system infections, 4% due to measles, and 12% due to other infectious diseases. Nationally, in 2005 about 59 000 and 34 000 children aged 5 to 14 years died from diarrheal diseases and pneumonia, corresponding to mortality of 24.1 and 13.9 per 100 000 respectively. Mortality was nearly 50% higher in girls than in boys for both diarrheal diseases and pneumonia.Approximately 60% of all deaths in this age group are due to infectious diseases and nearly half of these deaths are due to diarrheal diseases and pneumonia. Mortality in this age group from infectious diseases, and diarrhea in particular, is much higher than previously estimated.

In south Asia, where diarrhea is common and antibiotics are accessible without prescription, antimicrobial resistance is an emerging and serious problem. However, beliefs and behaviors related to antimicrobial resistance are poorly understood. We explored laypersons' and health-care providers' (HCP) awareness and perceptions of antimicrobial resistance in the context of treatment of adult diarrheal disease in Karachi, Pakistan. In-depth, open-ended interviews were conducted with 40 laypersons and 45 HCPs in a lower-middle-class urban neighborhood. Interviews conducted in Urdu were audiotaped, transcribed, translated, and coded using applied thematic analysis. Slightly over half of laypersons and two-thirds of HCPs were aware that antimicrobial medication could lose effectiveness, but misperceptions were common. Laypersons and HCPs often believed that "the body becomes immune" or "bacteria attack more strongly" if medications are taken "improperly." Another prevalent theme was that causes and effects of antimicrobial resistance are limited to the individual taking the antimicrobial medication and to the specific diarrheal episode. Participants often attributed antimicrobial resistance to patient behaviors; HCP behavior was rarely discussed. Less than half of the HCPs were aware of treatment guidelines. To combat antimicrobial resistance in urban Pakistan, a health systems strategy and community-supported outreach campaigns on appropriate antimicrobial use are needed. © The American Society of Tropical Medicine and Hygiene.

Factors Associated with Non-typhoidal Salmonella Bacteremia versus Typhoidal Salmonella Bacteremia in Patients Presenting for Care in an Urban Diarrheal Disease Hospital in Bangladesh.

Directory of Open Access Journals (Sweden)

K M Shahunja

Full Text Available Non-typhoidal Salmonella (NTS and Salmonella enterica serovar Typhi bacteremia are the causes of significant morbidity and mortality worldwide. There is a paucity of data regarding NTS bacteremia in South Asia, a region with a high incidence of typhoidal bacteremia. We sought to determine clinical predictors and outcomes associated with NTS bacteremia compared with typhoidal bacteremia.We performed a retrospective age-matched case-control study of patients admitted to the Dhaka Hospital of the International Centre for Diarrhoeal Disease Research, Bangladesh, between February 2009 and March 2013. We compared demographic, clinical, microbiological, and outcome variables of NTS bacteremic patients with age-matched S. Typhi bacteremic patients, and a separate comparison of patients with NTS bacteremia and patients with NTS gastroenteritis.Of 20 patients with NTS bacteremia, 5 died (25% case fatality, compared to none of 60 age-matched cases of S. Typhi bacteremia. In univariate analysis, we found that compared with S. Typhi bacteremia, cases of NTS bacteremia had more severe acute malnutrition (SAM in children under five years of age, less often presented with a duration of fever ≥ 5 days, and were more likely to have co-morbidities on admission such as pneumonia and clinical signs of sepsis (p<0.05 in all cases. In multivariable logistic regression, SAM, clinical sepsis, and pneumonia were independent risk factors for NTS bacteremia compared with S. Typhi bacteremia (p<0.05 in all cases. Notably, we found marked differences in antibiotic susceptibilities, including NTS strains resistant to antibiotics commonly used for empiric therapy of patients suspected to have typhoid fever.Diarrheal patients with NTS bacteremia more often presented with co-morbidities and had a higher case fatality rate compared to those with typhoidal bacteremia. Clinicians in regions where both typhoid and NTS bacteremia are prevalent need to be vigilant about the

Addison's disease is a rare condition. Its onset of symptoms most often is nonspecific contributing to a diagnostic and therapeutic delay. Acute renal failure can be the first manifestation of this disease. We report the case of a patient with Addison's disease who was initially treated for acute renal failure due to multiple myeloma and whose diagnosis was adjusted thereafter. Patient's condition dramatically improved after treatment with intravenous rehydration; injectable hydrocortisone.

Rotavirus in Ireland: national estimates of disease burden, 1997 to 1998.

LENUS (Irish Health Repository)

Lynch, M

2012-02-03

BACKGROUND: We estimated the disease burden caused by rotavirus hospitalizations in the Republic of Ireland by using national data on the number of hospitalizations for diarrhea in children and laboratory surveillance of confirmed rotavirus detections. METHODS: We examined trends in diarrheal hospitalizations among children <5 years old as coded by ICD-9-CM for the period January, 1997, to December, 1998. We collated data on laboratory-confirmed rotavirus detections nationally for the same period among children <2 years old. We calculated the overall contribution of rotavirus to laboratory-confirmed intestinal disease in children <5 years old from INFOSCAN, a disease bulletin for one-third of the population. We compared data from all sources and estimated the proportion of diarrheal hospitalizations that are likely the result of rotavirus in children <5 years old. RESULTS: In children <5 years old, 9% of all hospitalizations are for diarrheal illness. In this age group 1 in 8 are hospitalized for a diarrheal illness, and 1 in 17 are hospitalized for rotavirus by 5 years of age. In hospitalized children <2 years old, 1 in 38 have a laboratory confirmed rotavirus infection. CONCLUSIONS: The disease burden of rotavirus hospitalizations is higher than in other industrialized countries. Access to comprehensive national databases may have contributed to the high hospitalization rates, as well as a greater tendency to hospitalize children with diarrhea in Ireland.

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.

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 (HRS) is a unique form of renal failure associated with advanced liver dise...

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

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.

Full Text Available ABSTRACT. The data generalized in the review characterize radionuclide method as a high informative technique in diagnosis of the row of acute diseases and traumas and complications of them. It was shown that each radionuclide technique decides the concrete clinical tests and has a strictly definite place in the diagnostic algorithm. Urgent radionuclide techniques give the important information for the choice of the treatment’s policy or operation’s volume in such acute diseases as tromboembolism, arterial occlusions, small bowel obstruction, acute cholecystitis and cholelithiasis, acute myocardial infarct, rhabdomyolysis, differentiation of acute urological and acute abdominal surgical diseases and so on. The main aim of the work of our radionuclide department is to perfect, modificate of urgent radionuclide techniques and to correct the place of them in urgent conditions’s diagnostic algorithm for increasing of the quality and the rapidity in diagnosis.

The epidemiology, clinical features, nutritional status, and causative agents of diarrhea were studied in 289 Bangladeshi children (147 boys and 142 girls) 2-5 years old. The use of improved diagnostic tests for amebiasis enabled for the first time analysis of the contribution of Entamoeba histolytica to total diarrheal illness in this community setting. The average incidence rate of diarrhea was 1.8/child-year, and the average number of diarrheal days was 3.7 days/child-year over an average observation period of 2.8 years/child. Seventy-five percent of the diarrheal episodes were sp. (10%), E. histolytica (8.7%), Campylobacter jejunii (5.8%), P. shigelloides (4.3%), and A. caviae (4.3%). The overall incidence rate of E. histolytica-associated diarrhea was 0.08/child-year. Visible blood and hemoccult test-detected blood loss was found in 7% and 25%, respectively, of cases of E. histolytica-associated diarrhea. Children who had recovered from a diarrheal episode with E. histolytica, but not E. dispar, had half the chance of developing subsequent E. histolytica-associated diarrhea, consistent with the development of species-specific acquired immunity. In conclusion, the use of modern diagnostic tests demonstrated that E. histolytica contributed to overall morbidity from diarrheal illness. Understanding the etiology, frequency, and consequences of acute diarrhea in children from a developing country should aid in the design of interventions to improve child health.

Aggressive and acute periodontal diseases.

Science.gov (United States)

Albandar, Jasim M

2014-06-01

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

Objective: To explore the relationship between the dynamic changes of plasma neuropeptide (β-EP, NT, NPY) levels and the pathogenesis as well as clinical outcomes of acute cardiovascular and cerebrovascular diseases. Methods: The concentrations of serum neuropeptides (β-EP, NT, NPY) were measured on the 1 st, 3 rd, 7 th, 14 th day after the onset of disease with RIA in 103 patients with acute cardiovascular and cerebrovascular diseases (38 cases of acute cerebral infarction, 32 cases of cerebral hemorrhage, 33 cases of acute myocardial infarction and acute heart failure) and 66 controls. Results: 1. NPY, NT and β-EP levels in patients with acute cardiovascular and cerebrovascular disease were significantly higher than those in controls (p<0.01). (F=39.54, p<0.01; F=33.38, p<0.01; F=8.38, p<0.01 For β-EP, NPY and NT respectively). 2. The plasma neuropeptide levels were highest at onset and gradually lowered till to normal levels on the 14 th day. Conclusion: Plasma neuropeptide levels were closely related to the pathogenesis and clinical outcome of acute cardiovascular and cerebrovascular diseases, study of which might be useful in the clinical management of the diseases

Full Text Available Glutaric Aciduria type I (GA-I is a rare organic acidemia, caused by mutations in the GCDH gene, and characterized by encephalopathic crises with neurological sequelae. We report herein a patient with GA-I who presented with severe acute renal failure requiring dialysis, following an acute diarrheal illness. Histopathological evaluation demonstrated acute tubular necrosis, and molecular diagnosis revealed the patient to be homozygous for a previously unreported mutation, p.E64D. As renal impairment is not part of the clinical spectrum typical to GA-I, possible associations of renal failure and the underlying inborn error of metabolism are discussed, including recent advancements made in the understanding of the renal transport of glutaric acid and its derivatives during metabolic disturbance in GA-I.

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.)

Acute tubulointerstitial nephritis complicating Legionnaires' disease: a case report

2012-04-01

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.

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.

Enteroaggregative Escherichia coli (EAEC) is frequently found in diarrheal stools worldwide. It has been associated with persistent diarrhea, weight loss, and failure to thrive in children living in developing countries. A number of important EAEC virulence genes are identified; however, their roles in acute and persistent diarrhea have not been previously investigated. The aim of this study was to identify specific EAEC virulence genes associated with duration and type of diarrhea in Danish children. We aimed to improve the current diagnostics of EAEC and enable targeting of strains with an expected severe disease course. Questionnaires answered by parents provided information regarding duration of diarrhea and presence of blood or mucus. A total of 295 EAEC strains were collected from children with acute (≤7 days) and persistent diarrhea (≥14 days) and were compared by using multiplex PCR targeting the genes sat, sepA, pic, sigA, pet, astA, aatA, aggR, aaiC, aap, agg3/4C, ORF3, aafA, aggA, agg3A, agg4A, and agg5A. Furthermore, the distribution of EAEC genes in strains collected from cases of bloody, mucoid, and watery diarrhea was investigated. The classification and regression tree analysis (CART) was applied to investigate the relationship between EAEC virulence genes and diarrheal duration and type. Persistent diarrhea was associated with strains lacking the pic gene (p = 0.002) and with the combination of the genes pic, sat, and absence of the aggA gene (p = 0.05). Prolonged diarrhea was associated with the combination of the genes aatA and astA (p = 0.03). Non-mucoid diarrhea was associated with strains lacking the aatA gene (p = 0.004). Acute diarrhea was associated with the genes aggR, aap, and aggA by individual odds ratios. Resistance toward gentamicin and ciprofloxacin was observed in 7.5 and 3% of strains, respectively. Multi-drug resistance was observed in 38% of strains. Genetic host factors have been associated with an increased risk of EAEC

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

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

Levy, Karen; Smith, Shanon M; Carlton, Elizabeth J

2018-06-01

Climate change threatens progress achieved in global reductions of infectious disease rates over recent decades. This review summarizes literature on potential impacts of climate change on waterborne diseases, organized around a framework of questions that can be addressed depending on available data. A growing body of evidence suggests that climate change may alter the incidence of waterborne diseases, and diarrheal diseases in particular. Much of the existing work examines historical relationships between weather and diarrhea incidence, with a limited number of studies projecting future disease rates. Some studies take social and ecological factors into account in considerations of historical relationships, but few have done so in projecting future conditions. The field is at a point of transition, toward incorporating social and ecological factors into understanding the relationships between climatic factors and diarrheal diseases and using this information for future projections. The integration of these components helps identify vulnerable populations and prioritize adaptation strategies.

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

Minimal Residual Disease in Acute Myeloid Leukemia: Still a Work in Progress?

Directory of Open Access Journals (Sweden)

Federico Mosna

2017-06-01

Full Text Available Minimal residual disease evaluation refers to a series of molecular and immunophenotypical techniques aimed at detecting submicroscopic disease after therapy. As such, its application in acute myeloid leukemia has greatly increased our ability to quantify treatment response, and to determine the chemosensitivity of the disease, as the final product of the drug schedule, dose intensity, biodistribution, and the pharmakogenetic profile of the patient. There is now consistent evidence for the prognostic power of minimal residual disease evaluation in acute myeloid leukemia, which is complementary to the baseline prognostic assessment of the disease. The focus for its use is therefore shifting to individualize treatment based on a deeper evaluation of chemosensitivity and residual tumor burden. In this review, we will summarize the results of the major clinical studies evaluating minimal residual disease in acute myeloid leukemia in adults in recent years and address the technical and practical issues still hampering the spread of these techniques outside controlled clinical trials. We will also briefly speculate on future developments and offer our point of view, and a word of caution, on the present use of minimal residual disease measurements in “real-life” practice. Still, as final standardization and diffusion of the methods are sorted out, we believe that minimal residual disease will soon become the new standard for evaluating response in the treatment of acute myeloid leukemia.

2012-12-27

We describe a patient with sudden onset of abdominal pain and ascites, leading to the diagnosis of autosomal dominant polycystic kidney disease (ADPKD). Her presentation was consistent with acute liver cyst rupture as the cause of her acute illness. A review of literature on polycystic liver disease in patients with ADPKD and current management strategies are presented. This case alerts physicians that ADPKD could occasionally present as an acute abdomen; cyst rupture related to ADPKD may be considered in the differential diagnoses of acute abdomen.

Phytotherapy of Acute Respiratory Viral Diseases

2016-11-01

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

The association of acute nonlymphocytic leukemia with Hodgkin disease has been recorded in more than 100 instances. In most of these cases the patient has had long-standing Hodgkin disease and radiotherapy has been carried out. The combination of previous radiotherapy and chemotherapy appears to further increase the risk of leukemia developing. In a patient under our care with Hodgkin disease acute myelomonocytic leukemia developed following splenectomy for hypersplenism. The onset of acute leukemia immediately following splenectomy in a patient with Hodgkin disease has not previously been noted. In addition, because the patient's usual bone marrow sampling sites were hypoplastic, we utilized an 111 In-chloride bone marrow scan to find a site that was accessible for aspiration

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

Junod, Alain F

2014-01-22

The chronic obstructive pulmonary disease or COPD is a slowly progressive disease whose course is frequently the subject of acute episodes, of variable severity, although, in general, reversible, called acute exacerbations. In the past five years (between 2008 and 2013), seven prognostic scores have been published to try to assess the short-term risk of these acute exacerbations. Their components and characteristics are analysed and commented upon. An Internet program with a detailed compilation of the main features of these scores (www.medhyg.ch/scoredoc) supplements this review.

Escherichia coli Shiga Toxin Mechanisms of Action in Renal Disease

Directory of Open Access Journals (Sweden)

Tom G. Obrig

2010-12-01

Full Text Available Shiga toxin-producing Escherichia coli is a contaminant of food and water that in humans causes a diarrheal prodrome followed by more severe disease of the kidneys and an array of symptoms of the central nervous system. The systemic disease is a complex referred to as diarrhea-associated hemolytic uremic syndrome (D+HUS. D+HUS is characterized by thrombocytopenia, microangiopathic hemolytic anemia, and acute renal failure. This review focuses on the renal aspects of D+HUS. Current knowledge of this renal disease is derived from a combination of human samples, animal models of D+HUS, and interaction of Shiga toxin with isolated renal cell types. Shiga toxin is a multi-subunit protein complex that binds to a glycosphingolipid receptor, Gb3, on select eukaryotic cell types. Location of Gb3 in the kidney is predictive of the sites of action of Shiga toxin. However, the toxin is cytotoxic to some, but not all cell types that express Gb3. It also can cause apoptosis or generate an inflammatory response in some cells. Together, this myriad of results is responsible for D+HUS disease.

Jain, R.; Sawhney, S.; Rizvi, S.G.

2008-01-01

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

Acute pancreatitis has a highly variable course. Currently there is no widely accepted method to measure disease activity in patients hospitalized for acute pancreatitis. We aimed to develop a clinical activity index that incorporates routine clinical parameters to assist in the measurement, study, and management of acute pancreatitis. We used the UCLA/RAND appropriateness method to identify items for inclusion in the disease activity instrument. We conducted a systematic literature review followed by two sets of iterative modified Delphi meetings including a panel of international experts between November 2014 and November 2015. The final instrument was then applied to patient data obtained from five separate study cohorts across Southern California to assess profiles of disease activity. From a list of 35 items comprising 6 domains, we identified 5 parameters for inclusion in the final weighted clinical activity scoring system: organ failure, systemic inflammatory response syndrome, abdominal pain, requirement for opiates and ability to tolerate oral intake. We applied the weighted scoring system across the 5 study cohorts comprising 3,123 patients. We identified several distinct patterns of disease activity: (i) overall there was an elevated score at baseline relative to discharge across all study cohorts, (ii) there were distinct patterns of disease activity related to duration of illness as well as (iii) early and persistent elevation of disease activity among patients with severe acute pancreatitis defined as persistent organ failure. We present the development and initial validation of a clinical activity score for real-time assessment of disease activity in patients with acute pancreatitis.

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.

Some rural African communities residing along rivers use the untreated river water for domestic purposes, making them vulnerable to waterborne diseases such as diarrhea. We determined water use practices and water quality, relating them to prevalence of diarrhea in communities along the Boro-Thamalakane-Boteti river system, northern Botswana. A total of 452 households were interviewed and 196 water samples collected show during February, May, September, and December 2012 in settlements of Boro, Maun, Xobe, Samedupi, Chanoga, and Motopi. Information was sought on water use practices (collection, storage, and handling) and diarrheal experience using questionnaires. Water quality was assessed for physicochemical and microbiological parameters using portable field meters and laboratory analysis, respectively. All (100%) of the river water samples collected were fecally contaminated and unsuitable for domestic use without prior treatment. Samples had Escherichia coli (E.coli) and fecal streptococci levels reaching up to 186 and 140 CFU/100 ml, respectively. Study revealed high dependence on the fecally contaminated river water with low uptake of water treatment techniques. Up to 48% of households indicated that they experience diarrhea, with most cases occurring during the early flooding season (May). Nonetheless, there was no significant relationship between river water quality and households' diarrheal experience across studied settlements (p > 0.05). Failure to treat river water before use was a significant predictor of diarrhea (p = 0.028). Even though the river water was unsafe for domestic use, results imply further recontamination of water at household level highlighting the need for simple and affordable household water treatment techniques.

To explore the application value and forensic significance of ischemia modified albumin （IMA） in pericardial fluid to diagnose sudden cardiac death. IMA level in pericardial fluid was detected in acute ischemic heart disease group （ n =36）, acute myocardial infarction group （ n =6）, cardiomyopathy group （ n =4） and control group （ n =15） by albumin cobalt binding method. The levels of IMA were compared among these groups. The best cut-off IMA value was estimated and the sensitivity and specificity of acute myocardial ischemia group was distinguished from control group by receiver operating characteristics （ROC） curve. The IMA level in acute ischemic heart disease group was significantly higher than that of control group （ P 0.05）. The cut-off value for the identification of acute myocardial ischemia which obtained by ROC analysis was 40.65 U/mL. And the sensitivity and specificity for distinguishing acute ischemia cardiac disease was 60.0% and 80.5%, respectively. The IMA value in pericardial fluid can be a reference marker for the diagnosis of acute myocardial ischemia, which also can provide objective basis for the forensic identification of sudden cardiac death.

Enteroaggregative Escherichia coli (EAEC) is frequently found in diarrheal stools worldwide. It has been associated with persistent diarrhea, weight loss, and failure to thrive in children living in developing countries. A number of important EAEC virulence genes are identified; however, their roles in acute and persistent diarrhea have not been previously investigated. The aim of this study was to identify specific EAEC virulence genes associated with duration and type of diarrhea in Danish ...

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.

Full Text Available Hemolytic uremic syndrome (HUS is the most common cause of acute renal failure in children younger than 4 years and is characterized by microangiopathic hemolytic anemia, acute renal failure, and thrombocytopenia. HUS associated with diarrheal prodrome is usually caused by Shiga toxin-producing Escherichia coli O157:H7 or by Shigella dysenteriae, which generally has a better outcome. However, atypical cases show a tendency to relapse with a poorer prognosis. HUS has been reported to be associated with acute lymphoblastic leukemia (ALL in children. The characteristics and the mechanisms underlying this condition are largely unknown. In this study, we describe the case of an 11-year-old boy in whom the diagnosis of ALL was preceded by the diagnosis of atypical HUS. Thus, patients with atypical HUS should be diagnosed for the possibility of developing ALL.

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

In a multicountry birth cohort study, we describe rotavirus infection in the first 2 years of life in sites with and without rotavirus vaccination programs. Children were recruited by 17 days of age and followed to 24 months with collection of monthly surveillance and diarrheal stools. Data on sociodemographics, feeding, and illness were collected at defined intervals. Stools were tested for rotavirus and sera for antirotavirus immunoglobulins by enzyme immunoassays. A total of 1737 children contributed 22646 surveillance and 7440 diarrheal specimens. Overall, rotavirus was detected in 5.5% (408/7440) of diarrheal stools, and 344 (19.8%) children ever had rotavirus gastroenteritis. Household overcrowding and a high pathogen load were consistent risk factors for infection and disease. Three prior infections conferred 74% (P < .001) protection against subsequent infection in sites not using vaccine. In Peru, incidence of rotavirus disease was relatively higher during the second year of life despite high vaccination coverage. Rotavirus infection and disease were common, but with significant heterogeneity by site. Protection by vaccination may not be sustained in the second year of life in settings with high burdens of transmission and poor response to oral vaccines. © The Author 2017.

Full Text Available Summary Introduction: Acute diarrheal disease is the second cause of death in children under 5 years. In Brazil, from 2003 to 2009, acute diarrhea was responsible for nearly 100,000 hospital admissions per year and 4% of the deaths in children under 5 years. Rotavirus is the leading cause of severe acute diarrhea worldwide. In 2006, the rotavirus monovalent vaccine (RV1 was added to the Brazilian National Immunization Program. Objectives: To analyze the impact of the RV1 on emergency department (ED visits and hospital admissions for acute diarrhea. Method: A retrospective ecologic study at the University Hospital, University of São Paulo. The study analyzed the pre-vaccine (2003–2005 and the post-vaccine (2007–2009 periods. We screened the main diagnosis of all ED attendances and hospital admissions of children under 5 years in an electronic registry system database and calculated the rates of ED visits and hospital admissions. The reduction rate was analyzed according to the following formula: reduction (% = (1 - odds ratio x 100. Results: The rates of ED visits for acute diarrhea was 85.8 and 80.9 per 1,000 total ED visits in the pre and post vaccination periods, respectively, resulting in 6% reduction (95CI 4 to 9%, p<0.001. The rates of hospital admissions for acute diarrhea was 40.8 per 1,000 in the pre-vaccine period and dropped to 24.9 per 1,000 hospitalizations, resulting in 40% reduction (95CI 22 to 54%, p<0.001. Conclusion: The introduction of the RV1 vaccine resulted in 6% reduction in the ED visits and 40% reduction in hospital admissions for acute diarrhea.

Populations affected by armed conflict have experienced severe public health consequences mediated by population displacement, food scarcity, and the collapse of basic health services, giving rise to the term complex humanitarian emergencies. These public health effects have been most severe in underdeveloped countries in Africa, Asia, and Latin America. Refugees and internally displaced persons have experienced high mortality rates during the period immediately following their migration. In Africa, crude mortality rates have been as high as 80 times baseline rates. The most common causes of death have been diarrheal diseases, measles, acute respiratory infections, and malaria. High prevalences of acute malnutrition have contributed to high case fatality rates. In conflict-affected European countries, such as the former Yugoslavia, Georgia, Azerbaijan, and Chechnya, war-related injuries have been the most common cause of death among civilian populations; however, increased incidence of communicable diseases, neonatal health problems, and nutritional deficiencies (especially among the elderly) have been documented. The most effective measures to prevent mortality and morbidity in complex emergencies include protection from violence; the provision of adequate food rations, clean water and sanitation; diarrheal disease control; measles immunization; maternal and child health care, including the case management of common endemic communicable diseases; and selective feeding programs, when indicated.

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.

Haematopoietic stem cell transplantation (HSCT) is central to the management of many haematological disorders. A frequent complication of HSCT is acute graft-versus-host disease (GVHD), a condition in which immune cells from the donor attack healthy recipient tissues. The gastrointestinal system is among the most common sites affected by acute GVHD, and severe manifestations of acute GVHD of the gut portends a poor prognosis in patients after HSCT. Acute GVHD of the gastrointestinal tract presents both diagnostic and therapeutic challenges. Although the clinical manifestations are nonspecific and overlap with those of infection and drug toxicity, diagnosis is ultimately based on clinical criteria. As reliable serum biomarkers have not yet been validated outside of clinical trials, endoscopic and histopathological evaluation continue to be utilized in diagnosis. Once a diagnosis of gastrointestinal acute GVHD is established, therapy with systemic corticosteroids is typically initiated, and non-responders can be treated with a wide range of second-line therapies. In addition to treating the underlying disease, the management of complications including profuse diarrhoea, severe malnutrition and gastrointestinal bleeding is paramount. In this Review, we discuss strategies for the diagnosis and management of acute GVHD of the gastrointestinal tract as they pertain to the practising gastroenterologist.

Acute thyroid eye disease (TED): principles of medical and surgical management.

Science.gov (United States)

Verity, D H; Rose, G E

2013-03-01

The active inflammatory phase of thyroid eye disease (TED) is mediated by the innate immune system, and management is aimed at aborting this self-limited period of autoimmune activity. In most patients with TED, ocular and adnexal changes are mild and management involves controlling thyroid dysfunction, cessation of smoking, and addressing ocular surface inflammation and exposure. In patients with acute moderate disease, this being sufficient to impair orbital functions, immunosuppression reduces the long-term sequelae of acute inflammation, and adjunctive fractionated low-dose orbital radiotherapy is used as a steroid-sparing measure. Elective surgery is often required following moderate TED, be it for proptosis, diplopia, lid retraction, or to debulk the eyelid, and this should be delayed until the disease is quiescent, with the patient stable and weaned off all immunosuppression. Thus, surgical intervention during the active phase of moderate disease is rarely indicated, although clinical experience suggests that, where there is significant orbital congestion, early orbital decompression can limit progression to more severe disease. Acute severe TED poses a major risk of irreversible loss of vision due to marked exposure keratopathy, 'hydraulic' orbital congestion, or compressive optic neuropathy. If performed promptly, retractor recession with or without a suture tarsorrhaphy protects the ocular surface from severe exposure and, in patients not responding to high-dose corticosteroid treatment, decompression of the deep medial orbital wall and floor can rapidly relieve compressive optic neuropathy, as well as alleviate the inflammatory and congestive features of raised orbital pressure.

Health Care Seeking Behavior of Persons with Acute Chagas Disease in Rural Argentina: A Qualitative View

Directory of Open Access Journals (Sweden)

Ignacio Llovet

2016-01-01

Full Text Available 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.

Diagnostics of vascular diseases as a cause for acute abdomen

Juchems, M.S.; Aschoff, A.J.

2010-01-01

Vascular pathologies are rare causes of an acute abdomen. If the cause is a vascular disease a rapid diagnosis is desired as vascular pathologies are associated with high mortality. A differentiation must be made between arterial and venous diseases. An occlusion of the superior mesenteric artery is the most common reason for acute mesenteric ischemia but intra-abdominal arterial bleeding is also of great importance. Venous pathologies include thrombotic occlusion of the portal vein, the mesenteric vein and the vena cava. Multi-detector computed tomography (MDCT) is predestined for the diagnostics of vascular diseases of the abdomen. Using multiphasic contrast protocols enables reliable imaging of the arterial and venous vessel tree and detection of disorders with high sensitivity and specificity. Although conventional angiography has been almost completely replaced by MDCT as a diagnostic tool, it is still of high importance for minimally invasive interventions, for example in the management of gastrointestinal bleeding.

Acute exacerbation of chronic obstructive pulmonary disease (COPD) is a clinical diagnosis that is based on changes in dyspnea, cough, and/or sputum production in a COPD patient; however, patients presenting with an acute exacerbation may be undiagnosed or have a variety of comorbid conditions that can complicate diagnosis. This issue presents strategies and algorithms for the early use of evidence-based interventions, including appropriate use of antibiotics, bronchodilators, and corticosteroids, along with noninvasive ventilation with capnography, to minimize morbidity and mortality associated with this disease.

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

International Nuclear Information System (INIS)

Joensuu, H.

1989-01-01

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

Minimal Residual Disease in Acute Myeloid Leukemia

Hourigan, Christopher S.; Karp, Judith E.

2014-01-01

Technological advances in the laboratory have lead to substantial improvements in clinical decision-making by the use of pre-treatment prognostic risk stratification factors in acute myeloid leukemia (AML). Unfortunately similar progress has not been made in treatment response criteria, with the definition of “complete remission” in AML largely unchanged for over half a century. Several recent clinical trials have demonstrated that higher sensitivity measurements of residual disease burden during or after treatment can be performed, that results are predictive for clinical outcome and can be used to improve outcomes by guiding additional therapeutic intervention to patients in clinical complete remission but at increased relapse risk. We review here these recent trials, the characteristics and challenges of the modalities currently used to detect minimal residual disease (MRD), and outline opportunities to both refine detection and better clinically utilize MRD measurements. MRD measurement is already the standard of care in other myeloid malignancies such as chronic myelogenous leukemia (CML) and acute promyelocytic leukemia (APL). It is our belief that response criteria for non-APL AML should be updated to include assessment for molecular complete remission (mCR) and that recommendations for post-consolidation surveillance should include regular monitoring for molecular relapse as a standard of care.

Full Text Available Objective: to study the specific features of the diagnosis and treatment of endothoxicosis as a manifestation of postresus-citative disease in acute exogenous poisoning.Subjects and methods. Clinical, laboratory, and statistical methods of the diagnosis of endotoxicosis complicating the course of acute poisoning by narcotics, psychopharmacological agents, and cauterants, as well as complex physicochemical detoxification were applied to 554 patients.Results. The study pathology has been ascertained to have 3 developmental stages — from functional (primary to developed and terminal clinical and laboratory manifestations as multiple organ dysfunctions. The best therapeutic results are achieved by effective therapeutic measures just in early-stage endotoxicosis, by substantially reducing the rates of death and pneumonia and the time of the latter’s resolution. The major contribution to the reduction in the rate of death due acute poisoning is associated with physicochemical detoxification that considerably lessens the influence of the intoxication factors of postresuscitative disease.Conclusion. When diagnosing endotoxicosis in patients with acute endogenous intoxication, it is necessary to keep in mind a whole spectrum of typical changes in endotoxicosis markers and homeostatic parameters: hematologi-cal, blood rheological, lipid peroxidation/antioxidative systems, which should be timely corrected by the basic efferent artificial detoxification techniques (hemosorption, hemodiafiltration, hemofiltration, by compulsorily employing physio-and chemohemotherapy (laser-ultraviolet hemotherapy, sodium hypochlorite infusion. 

Splenectomy versus conservative management for acute sequestration crises in people with sickle cell disease.

2015-09-07

Acute splenic sequestration crises are a complication of sickle cell disease, with high mortality rates and frequent recurrence in survivors of first attacks. Splenectomy and blood transfusion, with their consequences, are the mainstay of long-term management used in different parts of the world. This is a 2015 update of a Cochrane review first published in 2002, and previously updated in 2013. To assess whether splenectomy (total or partial), to prevent acute splenic sequestration crises in people with sickle cell disease, improved survival and decreased morbidity in people with sickle cell disease, as compared with regular blood transfusions. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group Haemoglobinopathies Trials Register, which comprises of references identified from comprehensive electronic database searches and handsearching relevant journals and abstract books of conference proceedings.Additional trials were sought from the reference lists of the trials and reviews identified by the search strategy.Date of the most recent search: 10 June 2015. All randomized or quasi-randomized controlled trials comparing splenectomy (total or partial) to prevent recurrence of acute splenic sequestration crises with no treatment or blood transfusions in people with sickle cell disease. No trials of splenectomy for acute splenic sequestration were found. No trials of splenectomy for acute splenic sequestration were found. Splenectomy, if full, will prevent further sequestration and if partial, may reduce the recurrence of acute splenic sequestration crises. However, there is a lack of evidence from trials showing that splenectomy improves survival and decreases morbidity in people with sickle cell disease. There is a need for a well-designed, adequately-powered, randomized controlled trial to assess the benefits and risks of splenectomy compared to transfusion programmes, as a means of improving survival and decreasing mortality from acute splenic

Giardia duodenalis infection reduces granulocyte infiltration in an in vivo model of bacterial toxin-induced colitis and attenuates inflammation in human intestinal tissue.

Directory of Open Access Journals (Sweden)

James A Cotton

Full Text Available Giardia duodenalis (syn. G. intestinalis, G. lamblia is a predominant cause of waterborne diarrheal disease that may lead to post-infectious functional gastrointestinal disorders. Although Giardia-infected individuals could carry as much as 106 trophozoites per centimetre of gut, their intestinal mucosa is devoid of overt signs of inflammation. Recent studies have shown that in endemic countries where bacterial infectious diseases are common, Giardia infections can protect against the development of diarrheal disease and fever. Conversely, separate observations have indicated Giardia infections may enhance the severity of diarrheal disease from a co-infecting pathogen. Polymorphonuclear leukocytes or neutrophils (PMNs are granulocytic, innate immune cells characteristic of acute intestinal inflammatory responses against bacterial pathogens that contribute to the development of diarrheal disease following recruitment into intestinal tissues. Giardia cathepsin B cysteine proteases have been shown to attenuate PMN chemotaxis towards IL-8/CXCL8, suggesting Giardia targets PMN accumulation. However, the ability of Giardia infections to attenuate PMN accumulation in vivo and how in turn this effect may alter the host inflammatory response in the intestine has yet to be demonstrated. Herein, we report that Giardia infection attenuates granulocyte tissue infiltration induced by intra-rectal instillation of Clostridium difficile toxin A and B in an isolate-dependent manner. This attenuation of granulocyte infiltration into colonic tissues paralled decreased expression of several cytokines associated with the recruitment of PMNs. Giardia trophozoite isolates that attenuated granulocyte infiltration in vivo also decreased protein expression of cytokines released from inflamed mucosal biopsy tissues collected from patients with active Crohn's disease, including several cytokines associated with PMN recruitment. These results demonstrate for the first time

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.

Infectious diseases were one of the first health threats confronted by Coalition troops deployed to the Arabian desert in August 1990. On the basis of experiences in World War II, the major endemic infectious disease risks were thought to be sandfly fever, cutaneous leishmaniasis, diarrheal disease, and malaria. Although there was active surveillance, no case of sandfly fever and few other endemic infectious diseases were identified among over 500,000 U.S., British, and Canadian ground troops. In addition, there was no diagnosis of biological warfare (BW) exposure, and BW agents were not detected in clinical, environmental, or veterinary samples. The most common infectious disease problems were those associated with crowding (acute upper respiratory infections) and reduced levels of sanitation (travelers-type diarrhea). Only one endemic infectious disease has been confirmed as causing chronic health problems: visceral Leishmania tropica infection (viscerotropic leishmaniasis). However, this protozoan infection was diagnosed in only 12 U.S. veterans, and no new cases have been identified during the last 8 years. Infectious diseases were not a serious problem for Gulf War troops because of extensive preventive medicine efforts and favorable weather and geographic factors. Moreover, it is unlikely that an endemic infectious disease or a BW agent could cause chronic health problems and remain undetected over a 10-year period.

Recent developments in epigenetics of acute and chronic kidney diseases.

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.

Acute diseases of the thoracic aorta represent a relatively rare but life threatening spectrum of pathologies. The non-traumatic diseases are usually summarized by the term ''acute aortic syndrome''. A timely diagnosis and initiation of therapy are cornerstones for the patient outcome. CT has become the standard imaging procedure due do its widespread availability and excellent sensitivity. Furthermore, CT is able to discriminate the variants of acute aortic diseases and to detect the wide spectrum of complications. The volumetric CT dataset is also the basis for planning of interventional procedures. Open surgical repair still represents the standard of care for acute pathologies of the ascending aorta while endovascular therapy, due to minimally invasive character and good outcome, has replaced open surgery in most cases of complicated lesions of the descending aorta.

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.

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

To report clinical features of patients with retinal and choroidal diseases presenting with acute visual disturbance during pregnancy. In this retrospective case series, patients who developed acute visual loss during pregnancy (including puerperium) and visited a tertiary hospital from July 2007 to June 2015, were recruited by searching electronic medical records. Patients were categorized according to the cause of visual loss. Clinical features and required diagnostic modalities were analyzed in the retinal and choroidal disease group. Acute visual loss occurred in 147 patients; 49 (38.9%) were classified into the retinal and choroidal group. The diagnoses included central serous chorioretinopathy (22.4%), hypertensive retinopathy with or without pre-eclampsia (22.4%), retinal tear with or without retinal detachment (18.4%), diabetic retinopathy progression (10.2%), Vogt-Koyanagi-Harada disease (4.1%), retinal artery occlusion (4.1%), multiple evanescent white dot syndrome (4.1%), and others (14.3%). Visual symptoms first appeared at gestational age 25.9 ± 10.3 weeks. The initial best-corrected visual acuity (BCVA) was 0.27 ± 0.39 logarithm of the minimum angle of resolution (logMAR); the final BCVA after delivery improved to 0.13 ± 0.35 logMAR. Serious visual deterioration (BCVA worth than 20 / 200) developed in two patients. Differential diagnoses were established with characteristic fundus and spectral-domain optical coherence tomography findings in all cases. In pregnant women with acute visual loss, retinal and choroidal diseases are common and could be vision threatening. Physicians should be aware of pregnancy-associated retinal and choroidal diseases and their clinical features. The differential diagnosis can be established with non-invasive techniques. © 2017 The Korean Ophthalmological Society

To determine the features associated with acute onset systemic lupus erythaematosus (SLE). A total of 631 SLE patients from LUMINA (for "lupus in minority populations: nature vs nurture"), a multiethnic (Hispanics, African-Americans and Caucasians) cohort, were studied. Acute disease onset was defined as the accrual of > or = 4 American College of Rheumatology (ACR) criteria for the classification of SLE in < or = 4 weeks. Socioeconomic demographic features, clinical manifestations, disease activity, damage accrual, mortality, autoantibodies, HLA class II and FCGR alleles, behavioural/psychological variables were compared between patients with acute and insidious disease onset by univariable (chi(2) and Student t test) and multivariable (stepwise logistic regression) analyses. A total of 94 (15%) patients had acute disease onset. In the multivariable analysis, patients with acute onset lupus had more renal involvement (odds ratio (OR) = 1.845, 95% CI 1.076-3.162; p = 0.026) and higher disease activity (OR = 1.057, 95% CI 1.005-1.112; p = 0.030). By contrast, age (OR = 0.976, 95% CI 0.956-0.997; p = 0.025), education (OR = 0.901, 95% CI 0.827-0.983, p = 0.019), health insurance (OR = 0.423, 95% CI 0.249-0.718; p = 0.001) and skin involvement (OR = 0.346, 95% CI 0.142-0.843; p = 0.019) were negatively associated with acute onset lupus. No differences were found regarding the serological, genetic and behavioural/psychological features; this was also the case for damage accrual and mortality. Patients with acute onset lupus seem to be younger, have a lower socio-economic status and display more severe disease in terms of clinical manifestations and disease activity. However, intermediate (damage) and long-term (mortality) outcomes appear not to be influenced by the type of disease onset in SLE.

2006-08-01

Both neurologists and urologists might encounter patients with acute urinary retention due to benign inflammatory nervous diseases. Based on the mechanism of urinary retention, these disorders can be divided into two subgroups: disorders of the peripheral nervous system (e.g., sacral herpes) or the central nervous system (e.g., meningitis-retention syndrome [MRS]). Laboratory abnormalities include increased herpes virus titers in sacral herpes, and increased myelin basic protein in the cerebrospinal fluid (CSF) in some cases with MRS. Urodynamic abnormality in both conditions is detrusor areflexia; the putative mechanism of it is direct involvement of the pelvic nerves in sacral herpes; and acute spinal shock in MRS. There are few cases with CSF abnormality alone. Although these cases have a benign course, management of the acute urinary retention is necessary to avoid bladder injury due to overdistension. Clinical features of sacral herpes or MRS differ markedly from those of the original "Elsberg syndrome" cases.

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. (orig.)

Infectious diseases are mostly preventable but still pose a public health threat in the United States, where estimates of infectious diseases mortality are not available at the county level. To estimate age-standardized mortality rates and trends by county from 1980 to 2014 from lower respiratory infections, diarrheal diseases, HIV/AIDS, meningitis, hepatitis, and tuberculosis. This study used deidentified death records from the National Center for Health Statistics (NCHS) and population counts from the US Census Bureau, NCHS, and the Human Mortality Database. Validated small-area estimation models were applied to these data to estimate county-level infectious disease mortality rates. County of residence. Age-standardized mortality rates of lower respiratory infections, diarrheal diseases, HIV/AIDS, meningitis, hepatitis, and tuberculosis by county, year, and sex. Between 1980 and 2014, there were 4 081 546 deaths due to infectious diseases recorded in the United States. In 2014, a total of 113 650 (95% uncertainty interval [UI], 108 764-117 942) deaths or a rate of 34.10 (95% UI, 32.63-35.38) deaths per 100 000 persons were due to infectious diseases in the United States compared to a total of 72 220 (95% UI, 69 887-74 712) deaths or a rate of 41.95 (95% UI, 40.52-43.42) deaths per 100 000 persons in 1980, an overall decrease of 18.73% (95% UI, 14.95%-23.33%). Lower respiratory infections were the leading cause of infectious diseases mortality in 2014 accounting for 26.87 (95% UI, 25.79-28.05) deaths per 100 000 persons (78.80% of total infectious diseases deaths). There were substantial differences among counties in death rates from all infectious diseases. Lower respiratory infection had the largest absolute mortality inequality among counties (difference between the 10th and 90th percentile of the distribution, 24.5 deaths per 100 000 persons). However, HIV/AIDS had the highest relative mortality inequality between counties (10.0 as the

The severity of clinical activity of Crohn's disease is high during the first year after diagnosis and decreases thereafter. Approximately 50% of patients require steroids and immunosuppressants and 75% need surgery during their lifetime. The clinical course of patients with Crohn's disease first diagnosed at surgery has never been investigated. To assess the clinical course of Crohn's disease first diagnosed at surgery for acute abdomen and to evaluate the need for medical and surgical treatment in this subset of patients. Hospital clinical records of 490 consecutive Crohn's disease patients were reviewed. Patients were classified according to the Vienna criteria.

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

Recent advances in the treatment of colonic diverticular disease and prevention of acute diverticulitis

2016-01-01

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

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)

Acute kidney injury due to tropical infectious diseases and animal venoms: a tale of 2 continents.

South and Southeast Asia and Latin American together comprise 46 countries and are home to approximately 40% of the world population. The sociopolitical and economic heterogeneity, tropical climate, and malady transitions characteristic of the region strongly influence disease behavior and health care delivery. Acute kidney injury epidemiology mirrors these inequalities. In addition to hospital-acquired acute kidney injury in tertiary care centers, these countries face a large preventable burden of community-acquired acute kidney injury secondary to tropical infectious diseases or animal venoms, affecting previously healthy young individuals. This article reviews the epidemiology, clinical picture, prevention, risk factors, and pathophysiology of acute kidney injury associated with tropical diseases (malaria, dengue, leptospirosis, scrub typhus, and yellow fever) and animal venom (snakes, bees, caterpillars, spiders, and scorpions) in tropical regions of Asia and Latin America, and discusses the potential future challenges due to emerging issues.

Irradiation in the setting of collagen vascular disease: acute and late toxicity

International Nuclear Information System (INIS)

Morris, Monica; Powell, Simon

1996-01-01

Purpose: Based upon reports of greater toxicity from radiation therapy, collagen vascular diseases have been considered a contraindication to irradiation. We assessed the acute and late complication rate of radiation therapy in patients with collagen vascular disease. Methods and Materials: A retrospective chart review was undertaken to analyze acute and late toxicity in the 96 patients with documented collagen vascular disease (CVD) who were irradiated between 1960 and 1995. The majority had rheumatoid arthritis (55); 14 had systemic lupus erythematosus; 7 polymyositis or dermatomyositis; 7 ankylosing spondylitis; 4 scleroderma; 2 juvenile rheumatoid arthritis; and the remainder various mixed connective tissue disorders. Mean follow up of survivors was 6.3 years from time of irradiation. Treatment was megavoltage in all but 8 cases. Doses ranged from 6 to 70Gy, with an average of 41.7Gy. Treatment of 32 sites was combined with chemotherapy, 15 concurrent with irradiation. Surgery was involved in the treatment of 46 sites. Toxicity was scored using the RTOG acute and the RTOG/EORTC Late Effects on Normal Tissues radiation morbidity scoring scales. Results: Overall, 127 sites were evaluable in 96 patients. Significant (grade 3 or higher) acute complications were seen in 15 of 127 (11.8%) of irradiated sites. The actuarial incidence of significant late complications at 5 and 10 years was 16% and 24%, respectively. There was a single in-field sarcoma. 2 patients had treatment-related deaths, one from leukencephalopathy and the other from postoperative wound infection. Univariate analysis revealed late effects to be more severe in those receiving combined modality treatment (p=.03), and in those with significant acute reactions (p=.0001). Patients with rheumatoid arthritis had less severe late effects than those with other collagen vascular diseases (6% vs 37% at 5 years, p=.0001). We did not demonstrate a difference in late effects according to radiation dose, timing

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.

Noroviruses (NoVs) are a leading cause of acute gastroenteritis outbreaks and sporadic cases of diarrhea in industrialized countries. To study the prevalence and genetic diversity of NoVs in Guatemala, stool specimens were collected from hospitalized and ambulatory patients presenting with diarrhea (≥3 loose or liquid stools in a 24-hr period) who were enrolled in a prospective surveillance system in the Departments of Santa Rosa (October 2007 to August 2010) and Quetzaltenango (August 2009 to August 2010), Guatemala. Specimens were tested for rotavirus, enteric bacteria, and parasites by routine methods and for genogroups I and II NoV by real-time reverse transcription-PCR. A total of 2,403 stool specimens were collected from hospitalized (n = 528) and ambulatory patients (n = 1,875). Overall, 341 (14%) samples tested positive for NoVs including 114 (22%) hospitalized and 227 (12%) ambulatory patients. NoVs disease peaked during the winter (November-January) months. Among the 341 NoVs-positive patients, 32 (9%) were also positive for rotavirus, 32 (9%) for bacteria, and 9 (3%) for protozoa. Nucleotide sequences were obtained from 84 samples collected from hospitalized children aged Guatemala. The findings highlight the need to implement laboratory diagnostics for NoVs to improve appropriate clinical management of diarrheal diseases and guide vaccine development.

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.

Objective: To determinate the safety of the surgical treatment of acute biliary pancreatitis and acute cholecystitis in elderly patients. Study Design: Observational study. Place and Duration of Study: Department of General Surgery, Elazig Training and Research Hospital, Elazig, Turkey, from January 2010 to July 2012. Methodology: Records of 172 patients with acute complications of biliary calculi, aged over 65 years, were included. Patients were assessed for demographic information, hospitalisation diagnosis, leucocyte count, ASA classification, treatment type, conversion rates, length of hospital stay, morbidity and mortality. Statistical analyses were performed using the SPSS version 20.0. Result: The sample included 128 females (74.4 percentage) and 44 males (25.6 percentage). Patients' diagnoses included 135 (78.4 percentage) acute cholecystitis and 37 (21.6 percentage) acute pancreatitis. Medical treatment was offered to 113 patients (65.7 percentage). Open cholecystectomy was directly performed in 17 patients (9.9 percentage). Two patients (4.8 percentage) were converted to an open cholecystectomy during surgery, while a laparoscopic cholecystectomy was performed sucessfully on 42 patients (24.4 percentage). Those who underwent surgery were discharged as cured, except for minimal surgical complications. Conclusion: Treatment choice in acute gallstone complications in the elderly depends on the patient's general condition, severity of the disease, and ASA score. Early laparoscopic cholecystectomy is a good option in selected elderly patients with acute cholecystitis and non-severe acute biliary pancreatitis. (author)

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.)

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

Sista, Akhilesh K.; Vedantham, Suresh; Kaufman, John A.

2015-01-01

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.

Serum levels of dehydroepiandrosterone (DHEA) and DHEA sulphate (DHEAS) are low in chronic inflammatory diseases, although the reasons are unexplained. Furthermore, the behaviour of serum levels of these hormones during an acute inflammatory stressful disease state is not well known. In this study in patients with an acute inflammatory stressful disease state (13 patients undergoing cardiothoracic surgery) and patients with chronic inflammation (61 patients with inflammatory bowel diseases (IBD)) vs. 120 controls, we aimed to investigate adrenal hormone shifts looking at serum levels of DHEA in relation to other adrenal hormones. Furthermore, we tested the predictive role of serum tumour necrosis factor (TNF) and interleukin-6 (IL-6) for a change of serum levels of DHEA in relation to other adrenal hormones. The molar ratio of serum levels of DHEA/androstenedione (ASD) was increased in patients with an acute inflammatory stressful disease state and was decreased in patients with chronic inflammation. The molar ratio of serum levels of DHEAS/DHEA was reduced during an acute inflammatory stressful disease state and was increased in patients with chronic inflammation. A multiple linear regression analysis revealed that elevated serum levels of TNF were associated with a high ratio of serum levels of DHEA/ASD in all groups (for IL-6 in patients with an acute inflammatory stressful disease state only), and, similarly, elevated serum levels of TNF were associated with a high ratio of serum levels of DHEAS/DHEA only in IBD (for IL-6 only in healthy subjects). This study indicates that changes of serum levels of DHEA in relation to serum levels of other adrenal hormones are completely different in patients with an acute inflammatory stressful disease state compared with patients with chronic inflammation. The decrease of serum levels of DHEAS and DHEA is typical for chronic inflammation and TNF and IL-6 play a predictive role for these changes.

Mitochondria have various roles in cellular metabolism and homeostasis. Because mitochondrial dysfunction is associated with many acute and chronic degenerative diseases, mitochondrial biogenesis (MB) is a therapeutic target for treating such diseases. Here, we review the role of mitochondrial dysfunction in acute and chronic degenerative diseases and the cellular signaling pathways by which MB is induced. We then review existing work describing the development and application of drugs that induce MB in vitro and in vivo. In particular, we discuss natural products and modulators of transcription factors, kinases, cyclic nucleotides, and G protein-coupled receptors.

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

Directory of Open Access Journals (Sweden)

Jan S Suchodolski

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

Conventional wisdom supports prescribing "fibrates before statins", that is, prioritizing treatment of hypertriglyceridemia (hTG) to prevent pancreatitis ahead of low-density lipoprotein cholesterol to prevent coronary heart disease. The relationship between hTG and acute pancreatitis, however, may not support this approach to clinical management. This study analyzed administrative data from the Veterans Health Administration for evidence of (1) temporal association between assessed triglycerides level and days to acute pancreatitis admission; (2) association between hTG and outcomes in the year after hospitalization for acute pancreatitis; (3) relative rates of prescription of fibrates vs statins in patients with acute pancreatitis; (4) association of prescription of fibrates alone versus fibrates with statins or statins alone with rates of adverse outcomes after hospitalization for acute pancreatitis. Only modest association was found between above-normal or extremely high triglycerides and time until acute pancreatitis. CHD/MI/stroke occurred in 23% in the year following AP, supporting cardiovascular risk management. Fibrates were prescribed less often than statins, defying conventional wisdom, but the high rates of cardiovascular events in the year following AP support a clinical focus on reducing cardiovascular risk factors.

Full Text Available Microvillus inclusion disease is one of the congenital diarrheal disorders characterized by the appearance of inclusion bodies on the intestinal epithelium. To date there are a few cases and also a few other associated finding reports related to this life-threatening disease in literature. In this report, we present a premature infant with microvillus inclusion disease that was associated with necrotizing enterocolitis. Thus, we should be aware of the appearance of necrotizing enterocolitis in patients with microvillus inclusion disease, especially when contributing factors are present.

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. PMID:23646042

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

2017-05-01

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.

Current Understanding of Acute Bovine Liver Disease in Australia

Directory of Open Access Journals (Sweden)

Elizabeth Read

2016-12-01

Full Text Available Acute bovine liver disease (ABLD is a hepatotoxicity principally of cattle which occurs in southern regions of Australia. Severely affected animals undergo rapid clinical progression with mortalities often occurring prior to the recognition of clinical signs. Less severely affected animals develop photosensitization and a proportion can develop liver failure. The characteristic histopathological lesion in acute fatal cases is severe, with acute necrosis of periportal hepatocytes with hemorrhage into the necrotic areas. Currently there are a small number of toxins that are known to cause periportal necrosis in cattle, although none of these have so far been linked to ABLD. Furthermore, ABLD has frequently been associated with the presence of rough dog’s tail grass (Cynosurus echinatus and Drechslera spp. fungi in the pasture system, but it is currently unknown if these are etiological factors. Much of the knowledge about ABLD is contained within case reports, with very little experimental research investigating the specific cause(s. This review provides an overview of the current and most recently published knowledge of ABLD. It also draws on wider research and unpublished reports to suggest possible fungi and mycotoxins that may give rise to ABLD.

Diverticular disease of the colon is a common disorder, characterized by recurrent symptoms and complications such as diverticulitis, requiring hospital admissions and surgery. This study aimed to systematically review the evidence for medical therapy of diverticular disease in reducing symptoms and preventing acute diverticulitis. MEDLINE and Embase databases (1966 to February 2010). The studies selected were prospective clinical trials on uncomplicated diverticular disease of the colon. Four investigators independently reviewed articles, extracted data, and assessed study quality according to standardized criteria. The main outcomes measured were improvement in symptoms, complete remission of symptoms, and prevention of acute diverticulitis. We identified 31 studies, including 6 placebo-controlled trials. The methodological quality of these studies was suboptimal. Only 10 trials provided a detailed description of the patient history, 8 assessed symptoms by the use of a validated questionnaire, and 14 appropriately defined inclusion and exclusion criteria. Only one long-term double-blind placebo-controlled study was identified. This reported a significant improvement in symptoms and greater prevalence of symptom-free patients at 1 year with fiber plus rifaximin in comparison with fiber alone. The efficacy of treatment in preventing acute diverticulitis was evaluated in 11 randomized trials. Four trials compared rifaximin plus fiber vs fiber alone and failed to show a significant difference between treatments. However, cumulative data from these trials revealed a significant benefit following rifaximin and fiber (1-year rate of acute diverticulitis: 11/970 (1.1%) vs 20/690 (2.9%); P = .012), but with a number needed to treat of 57, to prevent an attack of acute diverticulitis. : Heterogeneity of the study design, patients' characteristics, regimens and combination of studied treatment, and outcome reporting precluded the pooling of results and limited

Objectives. We investigated the effects of failing sanitation, poor housing conditions, and fecal pollution in runoff water on the health—particularly the incidence of diarrheal disease—of residents of low-cost housing settlements in Cape Town, South Africa. Methods. In November 2009, we conducted a cross-sectional survey with structured interviews in 4 communities (n = 336 dwellings; 1080 persons). We used Colilert defined-substrate technology to determine Escherichia coli levels in runoff water samples taken from the study communities. Results. Almost 15% of households disposed of soiled products in storm water drains and 6% disposed of soiled products in the street. In only 26% of the dwellings were toilets washed daily. Approximately 59% of dwellings lacked a tap near the toilet for hand washing, and 14% of respondents suffered 1 or more attacks of diarrhea in the 2 weeks preceding their interview. E.coli counts of runoff environmental water samples ranged from 750 to 1 580 000 000 per 100 milliliters. Conclusions. A holistic and integrated approach is needed to improve housing quality and sanitation among Cape Town's low-income citizens. PMID:21566018

A 19-year old female with a bloody, diarrheal illness of acute onset where Crohn's disease primarly was suspected is presented. The double-contrast barium enema revealed multiple, diffusely scattered aphthous erosions of the colonic mucosa: the rectum was scarcely affected. Biopsies taken by endoscopy demonstrated nonspecific inflammatory changes of the mucous membrane. However, routinely taken stool cultures revealed an infectious colitis due to Yersinia enterocolitica. Our case demonstrates the necessity to consider Yersinia enterocolitis in the radiographic differential diagnosis when the diagnosis of Crohn's disease or ulcerative colitis seems obvious.

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

International Nuclear Information System (INIS)

LeBoit, P.E.

1989-01-01

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

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

Directory of Open Access Journals (Sweden)

Amanda Feliciano da Silva

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

Thirty patients with acute cerebrovascular disease were evaluated by both computed tomography (CT) and magnetic resonance (MR) imaging. The 17 patients with cerebral infarction (CI) were evaluated within 24 hours and the 13 with intracerebral hemorrhage (ICH) within 6 hours of the onset of symptoms. All ICHs were detected in T2-weighted images and appeared as perifocal, ring-like areas of high signal intensity. T2-weighted images also demonstrated a ruptured aneurysm and an arteriovenous malformation. In T1-weighted images, all ICHs displayed high signal intensity, which paralleled the CT images and is characteristic of MR imaging with an ultra-low magnetic filed. These findings were obtained as early as 90 minutes from the onset of symptoms. In cases of CI, T2-weighted images obtained 3 - 7 hours after onset demonstrated the pathology more clearly than did CT. This study proved MR imaging useful in the evaluation of both ICH and CI in the acute stage. In addition, it was possible to differentiate ICH from CI in the acute stage by T2-weighted images alone.

Foodborne diseases are important worldwide, resulting in considerable morbidity and mortality. To our knowledge, we present the first global and regional estimates of the disease burden of the most important foodborne bacterial, protozoal, and viral diseases. We synthesized data on the number of foodborne illnesses, sequelae, deaths, and Disability Adjusted Life Years (DALYs), for all diseases with sufficient data to support global and regional estimates, by age and region. The data sources included varied by pathogen and included systematic reviews, cohort studies, surveillance studies and other burden of disease assessments. We sought relevant data circa 2010, and included sources from 1990-2012. The number of studies per pathogen ranged from as few as 5 studies for bacterial intoxications through to 494 studies for diarrheal pathogens. To estimate mortality for Mycobacterium bovis infections and morbidity and mortality for invasive non-typhoidal Salmonella enterica infections, we excluded cases attributed to HIV infection. We excluded stillbirths in our estimates. We estimate that the 22 diseases included in our study resulted in two billion (95% uncertainty interval [UI] 1.5-2.9 billion) cases, over one million (95% UI 0.89-1.4 million) deaths, and 78.7 million (95% UI 65.0-97.7 million) DALYs in 2010. To estimate the burden due to contaminated food, we then applied proportions of infections that were estimated to be foodborne from a global expert elicitation. Waterborne transmission of disease was not included. We estimate that 29% (95% UI 23-36%) of cases caused by diseases in our study, or 582 million (95% UI 401-922 million), were transmitted by contaminated food, resulting in 25.2 million (95% UI 17.5-37.0 million) DALYs. Norovirus was the leading cause of foodborne illness causing 125 million (95% UI 70-251 million) cases, while Campylobacter spp. caused 96 million (95% UI 52-177 million) foodborne illnesses. Of all foodborne diseases, diarrheal and

Intestinal parasitic infections are a major public health burden in tropical countries. Although all HIV/AIDS patients are susceptible to parasitic infections, those having lower immune status are at greater risk. The aim of this study was to determine the prevalence of intestinal parasitic infections in patients living with HIV/AIDS. This was a facility-based cross-sectional study. A total of 343 consecutively sampled HIV/AIDS patients from the HIV care clinic of Hawassa University Referral Hospital were included. Subjects were interviewed for demographic variables and diarrheal symptoms using structured questionnaires. Stool examinations and CD4 cells counts were also performed. The prevalence of intestinal parasitic infection was 47.8% among HIV/AIDS patients; single helminthic infection prevalence (22.7%) was higher than that the prevalence of protozoal infections (14.6%). About 54% of study participants had chronic diarrhea while 3.4% had acute diarrhea. The prevalence of intestinal parasites in patients with chronic diarrhea was significantly higher than in acute diarrhea (p intestinal parasite infections such as Ascaris lumbricoides, Taenia spp., and hookworm were commonly found, regardless of immune status or diarrheal symptoms. Opportunistic and non-opportunistic intestinal parasitic infection were more frequent in patients with a CD4 count of Intestinal parasitic infections should be suspected in HIV/AIDS-infected patients with advanced disease presenting with chronic diarrhea. Patients with low CD4 counts should be examined critically for intestinal parasites, regardless of diarrheal status.

Full Text Available Objectives: To describe the current recommendations on the best management of pediatric patients with acute diarrheal disease. Data source: PubMed, Scopus, Google Scholar. Data summary: There has been little progress in the use of oral rehydration salts (ORS in recent decades, despite being widely reported by international guidelines. Several studies have been performed to improve the effectiveness of ORS. Intravenous hydration with isotonic saline solution, quickly infused, should be given in cases of severe dehydration. Nutrition should be ensured after the dehydration resolution, and is essential for intestinal and immune health. Dietary restrictions are usually not beneficial and may be harmful. Symptomatic medications have limited indication and antibiotics are indicated in specific cases, such as cholera and moderate to severe shigellosis. Conclusions: Hydration and nutrition are the interventions with the greatest impact on the course of acute diarrhea.

In Germany there is a clear deficit in the non-operative treatment of chronic and complex diseases and pain disorders in acute care hospitals. Only about 20 % of the treatments are carried out in orthopedic hospitals. Hospitals specialized in manual medicine have therefore formed a working group on non-operative orthopedic manual medicine acute care clinics (ANOA). The ANOA has developed a multimodal assessment procedure called the OPS 8-977 which describes the structure and process quality of multimodal and interdisciplinary diagnosis and treatment of the musculoskeletal system. Patients are treated according to clinical pathways oriented on the clinical findings. The increased duration of treatment in the German diagnosis-related groups (DRG) system is compensated for with a supplemental remuneration. Thus, complex and multifactorial orthopedic diseases and pain disorders are conservatively and appropriately treated as inpatient departments of acute care hospitals.

Full text: Multifactor fundamental research under experimental and industrial conditions on farm and laboratory animals and also on humans blood serum of Chernobyl NPP clean-up workers conducted within 1982 - 2002 have enabled us to establish the existence of two previously unknown phenomena: the phenomenon of reversible redistribution of cytobiochemical parameters in the blood-interstices-lymph-blood system of irradiated animals, which supports compensatory maintenance of homeostasis. The phenomenon of specific immunochemical reactions to the radiological effect, involving the formation of high molecular mass glycoprotein (molecular mass - 200 - 250 kDa) - radiation antigens (SDR - specific radiation determinant) in the lymphoid system with epitopes specific to each form of radiation syndrome, after animals have been irradiated in doses inducing the development of the cerebral (1) , toxic (2) gastrointestinal (3) and typical (4) forms of acute radiation sickness. These two phenomena allowed us to develop a technologies for diagnosis, prophylaxis and therapy of radiation disease - enzyme immune assay (EIA), antiradiation vaccine, antiradiation serum, method of immune-lymph-plasmosorption. The important first step in effectiveness of therapy is an accurate assessment of severity of disease in early period after irradiation. The ideal markers for early and accurate assessment is high weight glycoprotein with specifics radiation induced features (SDR) mentioned above. This biology active substance isolated from lymph can induct the symptoms of radiation syndrome without previously radiation when it is administrated intramuscularly or intravenously to healthy animals. Enzyme immune assay (EIA) allowed researchers to indicate the significant levels of different forms of SDR in peripheral blood of animals in first 24 hours after radiation. Indication of high level of SDR -1 allowed to forecast a fast development of cerebral form of acute radiation disease. Determination

Objective: This study was done to evaluate frequency of acute renal failure ( ARF ), its causes and out come of the patients. Study Design: Descriptive analytic study Place and Duration of Study: March to Dec 2007 at Combined Military Hospital Lahore. Patients and Methods: All patients, admitted in different wards of the hospital, who developed acute renal failure (doubling of serum creatinine measured on two occasions 12 hours apart), were included in this study. Results: A total of 39 patients were included in the study. Males were 19 (48.71%) and 20 (51.28%) were female. Mean age of patients was 40.2 years (SD=18.0). The major cause was acute Gastroenteritis seen in 23 (58.97%) cases. Others developed ARF due to, Abruptio Placentae 5 (12.82%), Postoperative 5 (12.82%), Eclampsia 3 (7.69%) and Drug induced 3 (7.69%) . Oliguric phase developed in 28 (71.79%) patients and lasted for 8.45 +- 4.16 days. Of these 17 (60.71%) patients had acute gastroenteritis. Conclusion: Gastroenteritis is the most common and important cause of ARF though gynaecological and surgical etiologies must be kept in mind. It is evident that the gynaecological and surgical patients need critical peri-partum and peri-operative monitoring to prevent development of ARF. Early institution of therapy will prevent subsequent morbidity associated with this disease. (author)

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 Ka¯ne'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. capitata colonies 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.

Aim. A case-control study was conducted to determine the prevalence of G. lamblia, Cryptosporidium, spp and E. histolytica/dispar in diarrheal children at Yirgalem Hospital from February 2011 to August. Subjects and Methods. A total of 230 children participated in the study of which 115 (50%) were cases and 115 (50%) were controls. A single stool sample was collected and examined by direct saline wet mount, formol-ether concentration, and modified Ziehl-Neelsen. Results. Eighty-four (36.52%) were positive for at least one intestinal parasites (57 (49.56%) from diarrheal children and 27 (23.47%) out of nondiarrheal children). The prevalence of G. lamblia, Cryptosporidium spp, and E. histolytica/dispar was 15.65%, 9.56%, and 4.35% in children with diarrhea and 1.74%, 5.21%, and 1.74% in those without it, respectively. Cryptosporidium spp and E. histolytica/dispar revealed higher infection in males (10.81% and 5.4%, resp.) than in females (7.32% and 2.43%, resp.). G. lamblia infection was higher in females (29.27%) than in males (8.11%). Cryptosporidium spp infection was higher in the age groups of ≤4 years old (53.84%). Significant difference was seen between 10 and 13 (7.69%) years old. Higher prevalence of E. histolytica/dispar was found in 5-9 years (85.71%) than ≤4 years old (14.28%). Conclusion. Cryptosporidium spp, E. histolytica/dispar, and G. lamblia were higher in children with diarrhea than in those without it.

Antifibrinolytic amino acids for upper gastrointestinal bleeding in people with acute or chronic liver disease.

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

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

Recent studies have demonstrated that aldosterone levels measured in patients with heart failure or acute myocardial infarction (MI) are associated with long-term mortality, but the association with aldosterone levels in patients with coronary artery disease (CAD) outside these specific settings remains unknown. In addition, no clear mechanism has been elucidated to explain these observations. The present study was designed to evaluate the relationship between the level of aldosterone and the risk of death and acute ischaemic events in CAD patients with a preserved left ventricular (LV) function and no acute MI. In 799 consecutive CAD patients referred for elective coronary angioplasty measurements were obtained before the procedure for: aldosterone (median = 25 pg/mL), brain natriuretic peptide (BNP) (median = 35 pg/mL), hsC-reactive protein (median = 4.17 mg/L), and left ventricular ejection fraction (mean = 58%). Patients with acute MI or coronary syndrome (ACS) who required urgent revascularization were not included in the study. The primary endpoint, cardiovascular death, occurred in 41 patients during a median follow-up period of 14.9 months. Secondary endpoints-total mortality, acute ischaemic events (acute MI or ischaemic stroke), and the composite of death and acute ischaemic events-were observed in 52, 54, and 94 patients, respectively. Plasma aldosterone was found to be related to BMI, hypertension and NYHA class, and inversely related to age, creatinine clearance, and use of beta-blockers. Multivariate Cox model analysis demonstrated that aldosterone was independently associated with cardiovascular mortality (P = 0.001), total mortality (P = 0.001), acute ischaemic events (P = 0.01), and the composite of death and acute ischaemic events (P = 0.004). Reclassification analysis, using integrated discrimination improvement (IDI) and net reclassification improvement (NRI), demonstrated incremental predictive value of aldosterone (P acute MI, the level of

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.

Cholera is an acute watery diarrheal disease caused by infection with Vibrio cholerae. The disease has a high fatality rate when untreated and outbreaks of cholera have been increasing globally in the past decade, most recently in Haiti. We present the case of a 28-year-old Haitian male with a history of severe untreated mental health disorder that developed acute fatal watery diarrhea in mid-October 2010 in central Haiti after drinking from the local river. We believe he is the first or among the first cases of cholera in Haiti during the current epidemic. By reviewing his case, we extracted lessons for global health on the importance of mental health for overall health, the globalization of diseases in small communities, and the importance of a comprehensive approach to the health of communities when planning services in resource-poor settings.

The acute effect of smoking on serum high sensitivity CRP (hs-CRP) and plasma fibrinogen and its association with disease severity was studied by challenging 31 chronic obstructive pulmonary disease patients with cigarette smoking and repeatedly measuring these biomarkers before and after smoking. Fibrinogen and hs-CRP increased directly after smoking by 9.4 mg/dl (95% CI: 4.2-14.5) and 0.13 mg/l (95% CI: 0.03-0.23), respectively. Fibrinogen levels remained elevated after 35 min, whereas hs-CRP normalized. Pearson's correlation coefficient between the hs-CRP change and chronic obstructive pulmonary disease severity was 0.25 (p = 0.06). Fibrinogen and hs-CRP increased directly after smoking in the chronic obstructive pulmonary disease patients. Their association with disease risk and/or progression remains to be demonstrated.

Percutaneous transluminal coronary angioplasty has grown exponentially since its introduction. Currently, selection criteria include single-vessel and multivessel disease, stable and unstable angina, and acute infarction. The outcome depends on specific patient and antiographic characteristics. In ideal lesions, success rates should be greater than 90%, with low morbidity and mortality. With more severe and diffuse multivessel disease, success rates are lower and complication rates are higher. In these cases, percutaneous transluminal coronary angioplasty still offers a reasonable option, provided complete revascularization can be achieved or the angina-producing lesion dilated. Numerous issues remain unresolved, including (1) the role of percutaneous transluminal coronary angioplasty vs coronary surgery (currently being tested), (2) restenosis, which occurs in approximately 30% of treated lesions, and (3) organizational adjustments such as training and certification to maintain high standards of care

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.

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

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

The authors report clinical features and therapeutic response of 24 outpatients with acute Chagas' disease, and 3 in the initial chronic phase, referred to the Clinic for Infectious and Parasitic Diseases of the FMUSP "Clínicas" Hospital between 1974 and 1987. The following transmission routes were involved: triatominae in 7 cases, blood transfusion in 9, kidney transplantation and/or blood transfusion in 4, accidental in 1, oral route in 3, probably breast feeding in 1, congenital or breast feeding in 1, and congenital or blood transfusion in 1. Six patients infected by triatominac acquired the disease between 1974 and 1980 and one in 1987. The blood transfusion infected patients acquired the disease in Greater São Paulo, seven of whom after 1983. The acute phase Chagas' disease was oligosymptomatic in 4 patients: three of such patients being immunocompromised by drugs or other diseases. Another two adult immunocompromised patients developed myocarditis and congestive heart failure. Clinical features were severe in 5 from 6 children under two years, irrespective of the transmission route. Evaluation of the acute phase patients treated with benznidazol (4-10 mg/kg/day) showed: therapeutic failure in 4/16 (25.0%); possible cure in 9/16 (53.2%) and inconclusive results in 3/16 (18.8%). The antibody and complement-mediated lysis reaction was in keeping with the xenodiagnosis in 18/22 cases, having shown negative results after treatment earlier than classical serological reactions. One aplastic anaemia patient receiving corticosteroid presented lymphoproliferative disease 6 years after being treated with benznidazol for acute Chagas' disease.

Streptococcus suis is a zoonotic pathogen with worldwide distribution, responsible for more than 700 human cases globally reported. This infection affects mostly men, exposed to pig or pork, which leads to its usual classification as an occupational disease. We report a case of acute bacterial meningitis in a 44 years old male. According to his past medical history, the patient had chronic alcoholism and worked in a restaurant as a piglet roaster. Microbiological examination of blood and CSF revealed S. suis. After 14 days of ceftriaxone the patient fully recovered. The authors review the clinical reports previously described in Portugal. In all of them was possible to identify risk exposition to pork. We alert to this microorganism's importance in Portugal where it is probably underdiagnosed.

Clinical presentation of viral myocarditis can mimic acute coronary syndrome and making diagnosis of viral heart disease (VHD) may be challenging. The presence of coronary artery disease (CAD) does not always exclude VHD and these entities can coexist. However, the incidence of co-occurrence of CAD and VHD is not precisely known. Moreover, inflammatory process caused by viruses may result in atherosclerotic plaque destabilization. The goal of this work is to summarize the current knowledge about co-occurrence of VHD and CAD. This article presents the importance of inflammatory process in both diseases and helps to understand pathophysiological mechanisms underlying their coexistence. It provides information about making differential diagnosis between these entities, including clinical presentation, noninvasive imaging features and findings in endomyocardial biopsy. Although currently there are no standard therapy strategies in coexistence of VHD and CAD, we present some remarkable aspects of treatment of patients, in whom VHD co-occurs with CAD. Viral heart disease may occur both in patients without and with atherosclerotic plaques in coronary arteries. Destabilization of atherosclerotic plaques in coronary arteries can be facilitated by inflammatory process. Increased inflammatory infiltrates in the coronary lesions of patients with VHD can lead to plaques' instability and consequently trigger acute coronary syndrome. In this article we attempted to present that co-occurrence of VHD and CAD may have therapeutic implications and as specific antiviral treatment is currently available, proper diagnosis and treatment can improve patient's condition and prognosis.

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.

Etiologic studies of diarrhea are limited by uneven diagnostic methods and frequent asymptomatic detection of enteropathogens. Polymerase chain reaction-based stool pathogen quantification may help distinguish clinically significant infections. We performed a nested case-control study of diarrhea in infants from a community-based birth cohort in Tanzania. We tested 71 diarrheal samples and pre-diarrheal matched controls with a laboratory-developed TaqMan Array Card for 19 enteropathogens. With qualitative detection, no pathogens were significantly associated with diarrhea. When pathogen quantity was considered, rotavirus (odds ratio [OR] = 2.70 per log10 increase, P < 0.001), astrovirus (OR = 1.49, P = 0.01), and Shigella/enteroinvasive Escherichia coli (OR = 1.47, P = 0.04) were associated with diarrhea. Enterotoxigenic E. coli (0.15 SD decline in length-for-age z score after 3 months per log10 increase, P < 0.001) and Campylobacter jejuni/C. coli (0.11 SD decline, P = 0.003) in pre-diarrheal stools were associated with poor linear growth. Quantitative analysis can help refine the association between enteropathogens and disease in endemic settings. PMID:24189366

Chagasic cardiomyopathy, which is seen in Chagas Disease, is the most severe and life-threatening manifestation of infection by the kinetoplastid Trypanosoma cruzi. Adipose tissue and diet play a major role in maintaining lipid homeostasis and regulating cardiac pathogenesis during the development of Chagas cardiomyopathy. We have previously reported that T. cruzi has a high affinity for lipoproteins and that the invasion rate of this parasite increases in the presence of cholesterol, suggesting that drugs that inhibit cholesterol synthesis, such as statins, could affect infection and the development of Chagasic cardiomyopathy. The dual epidemic of diabetes and obesity in Latin America, the endemic regions for Chagas Disease, has led to many patients in the endemic region of infection having hyperlipidemia that is being treated with statins such as atorvastatin. The current study was performed to examine using mice fed on either regular or high fat diet the effect of atorvastatin on T. cruzi infection-induced myocarditis and to evaluate the effect of this treatment during infection on adipose tissue physiology and cardiac pathology. Atorvastatin was found to regulate lipolysis and cardiac lipidopathy during acute T. cruzi infection in mice and to enhance tissue parasite load, cardiac LDL levels, inflammation, and mortality in during acute infection. Overall, these data suggest that statins, such as atorvastatin, have deleterious effects during acute Chagas disease. PMID:27416748

Full Text Available The purpose. To study the factor structure and to establish the associative interaction of pathogenetic links of acute diseases development of the bronchopulmonary system in infants.Materials and methods. The examination group consisted of 59 infants (average age 13.8 ± 1.4 months sick with acute inflammatory bronchopulmonary diseases. Also we tested the level of 25-hydroxyvitamin D (25(ОНD, vitamin D-binding protein, hBPI, cathelicidin LL-37, ß1-defensins, lactoferrin in blood serum with the help of immunoenzymometric analysis. Selection of prognostically important pathogenetic factors of acute bronchopulmonary disease among infants was conducted using ROC-analysis. The procedure for classifying objects was carried out using Hierarchical Cluster Analysis by the method of Centroid-based clustering. Results. Based on the results of the ROC-analysis were selected 15 potential predictors of the development of acute inflammatory diseases of the bronchopulmonary system among infants. The factor analysis made it possible to determine the 6 main components . The biggest influence in the development of the disease was made by "the anemia factor", "the factor of inflammation", "the maternal factor", "the vitamin D supply factor", "the immune factor" and "the phosphorus-calcium exchange factor” with a factor load of more than 0.6. The performed procedure of hierarchical cluster analysis confirmed the initial role of immuno-inflammatory components. The conclusions. The highlighted factors allowed to define a group of parameters, that must be influenced to achieve a maximum effect in carrying out preventive and therapeutic measures. First of all, it is necessary to influence the "the anemia factor" and "the calcium exchange factor", as well as the "the vitamin D supply factor". In other words, to correct vitamin D deficiency and carry out measures aimed at preventing the development of anemia. The prevention and treatment of the pathological course of

Acute, vaso-occlusive pain is the most characteristic complication of sickle cell disease (SCD). Although there has been rigorous work examining the pathogenesis of vaso-occlusion, fewer studies have focused on approaches to the clinical management of acute pain. In this review, we will examine the epidemiology and management strategies of acute pain events and we will identify limitations in the best available studies. Most acute pain events in adults with SCD are managed at home without physician contact. Prior descriptions of the natural history of pain episodes from the Cooperative Study of Sickle Cell Disease relied on physician contact, limiting the generalizability of these findings to current practice. Patient-controlled analgesia has replaced on-demand therapy to become the standard for management of severe pain events in children and adults with SCD requiring hospital admission. Unfortunately, most clinical practice guidelines for the management of acute pain are not based on randomized clinical trials. As a result, our practice of pain management is primarily limited to expert opinion and inferences from observational studies. Additional clinical trials in management of acute pain in children and adults with SCD are critical for the development of evidence-based guidelines.

The small intestine is the most common location of intestinal graft-versus-host disease (GVHD). EGD with duodenal biopsies yields the highest diagnostic sensitivity, but the jejunum and ileum are not accessible by regular endoscopy. In contrast, wireless capsule endoscopy (WCE) is a noninvasive imaging procedure offering complete evaluation of the small intestine. The objective was to compare the diagnostic value of EGD, including biopsies, with the results of WCE in patients with acute intestinal symptoms who received allogeneic blood stem cell transplantation and to analyze the appearance and distribution of acute intestinal GVHD lesions in these patients. An investigator-blinded, single-center prospective study. Patients with acute intestinal symptoms after allogeneic stem cell transplantation underwent both EGD and WCE within 24 hours. Clinical data were recorded during 2 months of follow-up. Fourteen consecutive patients with clinical symptoms of acute intestinal GVHD were recruited. In 1 patient, the capsule remained in the stomach and was removed endoscopically. In 7 of 13 patients who could be evaluated, acute intestinal GVHD was diagnosed by EGD with biopsies, but 3 of these would have been missed by EGD alone. In all 7 patients with histologically confirmed acute intestinal GVHD, WCE revealed typical signs of GVHD. Lesions were scattered throughout the small intestine, but were most accentuated in the ileum. This study had a small number of patients. WCE, which is less invasive than EGD with biopsies, showed a comparable sensitivity and a high negative predictive value for diagnosing acute intestinal GVHD. It may be helpful to avoid repeated endoscopic procedures in patients who have undergone stem cell transplantation.

To assess the acute respiratory infection (ARI) disease spectrum, duration of hospitalisation and outcome in children hospitalised with an ARI in Viet Nam. We conducted a retrospective descriptive study of ARI admissions to primary (Hoa Vang District Hospital), secondary (Da Nang Hospital for Women and Children) and tertiary (National Hospital of Paediatrics in Ha Noi) level hospitals in Viet Nam over 12 months (01/09/2015 to 31/08/2016). Acute respiratory infections accounted for 27.9% (37 436/134 061) of all paediatric admissions; nearly half (47.6%) of all children admitted to Hoa Vang District Hospital. Most (64.6%) of children hospitalised with an ARI were Viet Nam, characterised by prolonged hospitalisation for relatively mild disease. There is huge potential to reduce unnecessary hospital admission and cost. © 2017 John Wiley & Sons Ltd.

BACKGROUND Gastrointestinal and liver diseases (GILDs) are major causes of death and disability in Middle East and North Africa (MENA). However, they have different patterns in countries with various geographical, cultural, and socio-economic status. We aimed to compare the burden of GILDs in Iran with its neighboring countries using the results of the Global Burden of Disease (GBD) Study in 2010. METHODS Classic metrics of GBD have been used including: age-standardized rates (ASRs) of death, years of life lost due to premature death (YLL), years of life lost due to disability (YLD), and disability adjusted life years (DALY). All countries neighboring Iran have been selected. In addition, all other countries classified in the MENA region were included. Five major groups of gastrointestinal and hepatic diseases were studied including: infections of gastrointestinal tract, gastrointestinal and pancreatobilliary cancers, acute hepatitis, cirrhosis, and other digestive diseases. RESULTS The overall burden of GILDs is highest in Afghanistan, Pakistan, and Egypt. Diarrheal diseases have been replaced by gastrointestinal cancers and cirrhosis in most countries in the region. However, in a number of countries including Afghanistan, Pakistan, Turkmenistan, Egypt, and Yemen, communicable GILDs are still among top causes of mortality and morbidity in addition to non-communicable GILDs and cancers. These countries are experiencing the double burden. In Iran, burden caused by cancers of stomach and esophagus are considerably higher than other countries. Diseases that are mainly diagnosed in outpatient settings have not been captured by GBD. CONCLUSION Improving the infrastructure of health care system including cancer registries and electronic recording of outpatient care is a necessity for better surveillance of GILDs in MENA. In contrast to expensive treatment, prevention of most GILDs is feasible and inexpensive. The health care systems in the region can be strengthened for

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

Directory of Open Access Journals (Sweden)

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.

What Can We Apply to Manage Acute Exacerbation of Chronic Obstructive Pulmonary Disease with Acute Respiratory Failure?

2018-04-01

Acute exacerbation(s) of chronic obstructive pulmonary disease (AECOPD) tend to be critical and debilitating events leading to poorer outcomes in relation to chronic obstructive pulmonary disease (COPD) treatment modalities, and contribute to a higher and earlier mortality rate in COPD patients. Besides pro-active preventative measures intended to obviate acquisition of AECOPD, early recovery from severe AECOPD is an important issue in determining the long-term prognosis of patients diagnosed with COPD. Updated GOLD guidelines and recently published American Thoracic Society/European Respiratory Society clinical recommendations emphasize the importance of use of pharmacologic treatment including bronchodilators, systemic steroids and/or antibiotics. As a non-pharmacologic strategy to combat the effects of AECOPD, noninvasive ventilation (NIV) is recommended as the treatment of choice as this therapy is thought to be most effective in reducing intubation risk in patients diagnosed with AECOPD with acute respiratory failure. Recently, a few adjunctive modalities, including NIV with helmet and helium-oxygen mixture, have been tried in cases of AECOPD with respiratory failure. As yet, insufficient documentation exists to permit recommendation of this therapy without qualification. Although there are too few findings, as yet, to allow for regular andr routine application of those modalities in AECOPD, there is anecdotal evidence to indicate both mechanical and physiological benefits connected with this therapy. High-flow nasal cannula oxygen therapy is another supportive strategy which serves to improve the symptoms of hypoxic respiratory failure. The therapy also produced improvement in ventilatory variables, and it may be successfully applied in cases of hypercapnic respiratory failure. Extracorporeal carbon dioxide removal has been successfully attempted in cases of adult respiratory distress syndrome, with protective hypercapnic ventilatory strategy. Nowadays, it is

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

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.

ABSTRACT 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.

2015-01-01

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

Some patients will develop chronic kidney disease after a hospitalization with acute kidney injury; however, no risk-prediction tools have been developed to identify high-risk patients requiring follow-up. To derive and validate predictive models for progression of acute kidney injury to advanced chronic kidney disease. Data from 2 population-based cohorts of patients with a prehospitalization estimated glomerular filtration rate (eGFR) of more than 45 mL/min/1.73 m2 and who had survived hospitalization with acute kidney injury (defined by a serum creatinine increase during hospitalization > 0.3 mg/dL or > 50% of their prehospitalization baseline), were used to derive and validate multivariable prediction models. The risk models were derived from 9973 patients hospitalized in Alberta, Canada (April 2004-March 2014, with follow-up to March 2015). The risk models were externally validated with data from a cohort of 2761 patients hospitalized in Ontario, Canada (June 2004-March 2012, with follow-up to March 2013). Demographic, laboratory, and comorbidity variables measured prior to discharge. Advanced chronic kidney disease was defined by a sustained reduction in eGFR less than 30 mL/min/1.73 m2 for at least 3 months during the year after discharge. All participants were followed up for up to 1 year. The participants (mean [SD] age, 66 [15] years in the derivation and internal validation cohorts and 69 [11] years in the external validation cohort; 40%-43% women per cohort) had a mean (SD) baseline serum creatinine level of 1.0 (0.2) mg/dL and more than 20% had stage 2 or 3 acute kidney injury. Advanced chronic kidney disease developed in 408 (2.7%) of 9973 patients in the derivation cohort and 62 (2.2%) of 2761 patients in the external validation cohort. In the derivation cohort, 6 variables were independently associated with the outcome: older age, female sex, higher baseline serum creatinine value, albuminuria, greater severity of acute kidney injury, and higher

Clostridium perfringens causes diarrhea in neonatal piglets, thereby affecting commercial swine farming. The objective of this study was to determine the prevalence and characterize antimicrobial resistance in C. perfringens isolated from diarrheal neonatal piglets in Thailand. A total of 260 rectal swab samples were collected from 13 farms and were subjected to C. perfringens isolation. A total of 148 samples were PCR-positive for C. perfringens toxin genes, from which 122 were recovered. All isolates were cpb2-encoding C. perfringens type A and enterotoxin gene negative. Most of the isolates were susceptible to ampicillin, bacitracin, chlorotetracycline, doxycycline, and oxytetracycline with MIC50 values ranging from 0.32 to 8 μg/ml. The high resistance rates were observed for ceftiofur, enrofloxacin, erythromycin, lincomycin, and tylosin. Among resistant isolates, 82% were resistant to more than one type of antibiotics. The distinct pattern of multiple drug resistance in C. perfringens was observed in different regions, potentially reflecting the farm specific usage of these agents. Copyright © 2016 Elsevier Ltd.

Full Text Available Pathogenetically, prescription of local action drugs containing a wide spectrum antiseptic is reasonable for the upper respiratory tract diseases accompanied by throat irritation and pain. It should be noted that such drugs are very popular among parents; however, most of these drugs may have a range of side effects, which considerably complicate their use in children. That is why the right choice of local action drugs for the acute inflammatory diseases accompanied by throat irritation and pain is a guarantee of treatment efficacy and high compliance. This article examines pharmacological qualities of an antiseptic-containing local action drug permitted to use in children over 4 years of age.

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

There was no effect of hygiene intervention on most anthropometric parameters (low to very low quality evidence). Hygiene intervention reduced the risk of developing Acute respiratory infections by 24% (RR 0.76; 95% CI 0.59, 0.98; moderate quality evidence), cough by 10% (RR 0.90; 95% CI 0.83, 0.97; moderate quality evidence), laboratory-confirmed influenza by 50% (RR 0.5; 95% CI 0.41, 0.62; very low quality evidence), fever by 13% (RR 0.87; 95% CI 0.74, 1.02; moderate quality evidence), and conjunctivitis by 51% (RR 0.49; 95% CI 0.45, 0.55; low quality evidence). There was low quality evidence to suggest no impact of intervention on mortality (RR 0.65; 95% CI 0.25, 1.7). Improvement in water supply and quality was associated with slightly higher weight-for-age Z-score (MD 0.03; 95% CI 0, 0.06; low quality evidence), but no significant impact on other anthropometric parameters or infectious morbidity (low to very low quality evidence). There was very low quality evidence to suggest reduction in mortality (RR 0.45; 95% CI 0.25, 0.81). Improvement in sanitation had a variable effect on the anthropometry and infectious morbidity. Combined water, sanitation and hygiene intervention improved height-for-age z scores (MD 0.22; 95% CI 0.12, 0.32) and decreased the risk of stunting by 13% (RR 0.87; 95% CI 0.81, 0.94) (very low quality of evidence).

Majority of acute diarrhoeal diseases are self-limiting and do not require routine treatment. Treatment with empirical antimicrobials is recommended only for dysenteric and invasive bacterial diarrhoea. Irrational use of antibiotics in treatment of acute diarrhoea is common in clinical practice worldwide. This study was carried out to assess the pattern of antibiotic use for acute diarrhoeal diseases in Bishoftu General Hospital, East Shewa Ethiopia. Institution based cross-sectional study was conducted from April 1 to April 30, 2016. Data were collected retrospectively from patients treated for diarrhoeal diseases from January 2015 to December 2015 using structured questionnaires and entered into SPSS (IBM 20) and descriptive statistics was carried out. Among the 303 patients, 51.2% were males and 48.8% were females. Of them, 62% were children under five years. Two hundred sixty three (86.8%) patients received eight different types of antibiotics and cotrimoxazole (178 patients, 58.7%) was the most prescribed antibiotics, followed by ciprofloxacin (33, 10.9%) and amoxicillin (14, 4.6%). Based on the presence of blood in stools, 14.5% of cases were of invasive bacterial type. According to the recommendations of WHO, the rate of overuse of antibiotics was 72.3%. This study revealed that there was high overuse of antibiotics for both adults and children under five with acute diarrhoea in Bishoftu General Hospital. And Cotrimoxazole was the most prescribed antibiotic.

We interviewed caretakers of 1,043 children 20,000 children on five separate subsequent occasions (May of 2009 to December 31, 2010) to assess healthcare seeking patterns for diarrhea. Diarrhea prevalence during the preceding 2 weeks ranged from 26% at baseline to 4–11% during 2009–2010. Caretakers were less likely to seek healthcare outside the home for infants (versus older children) with diarrhea (adjusted odds ratio [aOR] = 0.33, confidence interval [CI] = 0.12–0.87). Caretakers of children with reduced food intake (aOR = 3.42, CI = 1.37–8.53) and sunken eyes during their diarrheal episode were more likely to seek care outside home (aOR = 4.76, CI = 1.13–8.89). Caretakers with formal education were more likely to provide oral rehydration solution (aOR = 3.01, CI = 1.41–6.42) and visit a healthcare facility (aOR = 3.32, CI = 1.56–7.07). Studies calculating diarrheal incidence and healthcare seeking should account for seasonal trends. Improving caretakers' knowledge of home management could prevent severe diarrhea. PMID:23629929

The specificity of positive polymerase chain reaction results was confirmed by sequencing.Results: Two hundred two of 212 patients for whom PCR results were available both for nasal lavage and induced sputum samples were eligible for data analysis. HBoV DNA was detected in three patients (1.5%. Of those, only one patient had AE-COPD. Thus, the frequency of HBoV infection demonstrated to be low in both AE-COPD (0.8% and stable COPD (2.9%. HBoV was found in two sputum and one nasal lavage sample in different patients, respectively. Sequencing revealed >99% sequence identity with the reference strain.Conclusion: HBoV detection was infrequent. Since we detected HBoV in both upper and lower respiratory tract specimens and in AE-COPD as well as stable disease, a major role of HBoV infection in adults with AE-COPD is unlikely

CBA mice, lethally irradiated and injected with 20 x 10{sup 6} bone-marrow cells derived from C57BL donors, develop a chronic form of 'homologous disease' and die between 20 and 40 days after treatment. If 10 x 10{sup 6} lymph node cells are added to the bone-marrow suspension, all recipients develop 'acute' homologous disease and die 6 to 10 days after irradiation. Different parameters of the disease were systematically observed. Among them, changes in spleen weight indicated early cell proliferation, which reached its maximum on day 4 and progressively decreased later on. Chromosomal analysis showed that all dividing cells in the spleen were of donor origin. Their number decreased concomitantly with the shrinkage and devastation of the organ, which started on day 6. The period of devastation of the spleen fully corresponds to the time in which all animals die. The use of cyclophosphamide in the treatment of 'acute' homologous disease transformed the disease into a chronic form with a mortality very similar to that obtained when only bone-marrow cells were injected. Among other effects, treatment with cyclophosphamide prevented early proliferation of donor cells in the spleen, and delayed spleen weight increase for about 10 days. After that period spleen weight increased, reaching its maximum on day 12. At first only donor type cells could be detected, but towards the end of the period in which spleen weight increase was registered host type cells appeared among the cells in mitosis. Their number gradually increased, and in some cases the majority or all of the dividing cells were of the host type. After a transitional decrease in spleen weight, another peak in cellular proliferation consisting of either host or donor or both types of cells was observed about day 30. In spite of the observed irregularities in the origin of dividing cells, all animals died by day 40 after application of cyclophosphamide.

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

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.

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

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.

The world is increasingly threatened by a global epidemic of chronic diseases. Almost half of the global morbidity and almost two thirds of global mortality is due to these diseases-approximately 35 million die each year from chronic diseases. And they continue to increase. Increasing evidence suggest that these diseases are associated with lifestyle, stress, lack of physical exercise, over-consumption of calorie-condensed foods rich in saturated fat, sugar and starch, but also under-consumption of antioxidant-rich fruits and vegetables. As a result the function of the innate immune system is severe impaired. This review discusses the changes induced in response to mental and physical stress and their association with the subsequent development of metabolic syndrome, and its association with various chronic diseases. The endothelial cells and their function appears to be of great importance, and the function of their cellular membranes of special importance to the function of the underlying cells; their ability to obtain nutrients and antioxidants and to eliminate waste products. The abdominal adipocytes seen to play a key role, as they have the ability to in stressful situations release much of proinflammatory cytokines, PAI-1 and free fatty acids compared to elsewhere in the body. The load on the liver of these various substances in often of greater magnitude than the liver can handle. Some of the most common chronic diseases and their potential association with acute and "chronic" phase response, and with metabolic syndrome are discussed separately. The need for studies with lifestyle modifications is especially emphasized.

Disability-adjusted life years (DALYs) provide a summary measure of health and can be a critical input to guide health systems, investments, and priority-setting in Ethiopia. We aimed to determine the leading causes of premature mortality and disability using DALYs and describe the relative burden of disease and injuries in Ethiopia. We used results from the Global Burden of Diseases, Injuries, and Risk Factors Study 2015 (GBD 2015) for non-fatal disease burden, cause-specific mortality, and all-cause mortality to derive age-standardized DALYs by sex for Ethiopia for each year. We calculated DALYs by summing years of life lost due to premature mortality (YLLs) and years lived with disability (YLDs) for each age group and sex. Causes of death by age, sex, and year were measured mainly using Causes of Death Ensemble modeling. To estimate YLDs, a Bayesian meta-regression method was used. We reported DALY rates per 100,000 for communicable, maternal, neonatal, and nutritional (CMNN) disorders, non-communicable diseases, and injuries, with 95% uncertainty intervals (UI) for Ethiopia. Non-communicable diseases caused 23,118.1 (95% UI, 17,124.4-30,579.6), CMNN disorders resulted in 20,200.7 (95% UI, 16,532.2-24,917.9), and injuries caused 3781 (95% UI, 2642.9-5500.6) age-standardized DALYs per 100,000 in Ethiopia in 2015. Lower respiratory infections, diarrheal diseases, and tuberculosis were the top three leading causes of DALYs in 2015, accounting for 2998 (95% UI, 2173.7-4029), 2592.5 (95% UI, 1850.7-3495.1), and 2562.9 (95% UI, 1466.1-4220.7) DALYs per 100,000, respectively. Ischemic heart disease and cerebrovascular disease were the fourth and fifth leading causes of age-standardized DALYs, with rates of 2535.7 (95% UI, 1603.7-3843.2) and 2159.9 (95% UI, 1369.7-3216.3) per 100,000, respectively.

2012-06-01

Infectious mononucleosis (IM) is one of the representative, usually benign, acute diseases associated with primary Epstein-Barr virus (EBV) infection. IM is generally self-limiting and is characterized mostly by transient fever, lymphadenopathy and hepatosplenomegaly. However, very rarely primary EBV infection results in severe or fatal conditions such as hemophagocytic lymphohistiocytosis together with fulminant hepatitis designated as severe or fatal IM or EBV-associated hemophagocytic lymphohistiocytosis alone. In addition, chronic EBV-associated diseases include Burkitt's lymphoma, undifferentiated nasopharyngeal carcinoma, Hodgkin lymphoma, T-cell lymphoproliferative disorder (LPD)/lymphoma, natural killer-cell LPD including leukemia or lymphoma, gastric carcinoma, pyothorax-associated lymphoma and senile B-cell LPD as well as chronic active EBV infection and LPD/lymphoma in patients with immunodeficiency. The number of chronic life-threatening diseases linked to the EBV infection is increasingly reported and many of these diseases have a poor prognosis. This review will focus on the historical, pathogenetic, diagnostic, therapeutic and prophylactic issues of EBV-associated life-threatening diseases.

Patients with cardiovascular diseases are a group of increased risk of acute kidney injury (AKI). Mortality in this group of patients with AKI, especially treated in intensive care units, is very high. The aim of this study was to evaluate the clinical characteristic of patients with AKI complicated severe cardiovascular diseases. Retrospective evaluation of 246 questionnaire of patients with AKI in the course of severe cardiovascular diseases treated in the wards of nephrological profile from the malopolska and podkarpackie voivodships in the years 2000-2011 was performed. The group of patients consisted of 157 men and 89 women, with mean age 67.9 ± 14.8 years. The most common cause of AKI were: acute decompensated heart failure--24 (9.8%), chronic decompensated heart failure--94 (38.2%), cardiac arrest--29 (11.8%), myocardial infarction--48 (19.5%), CABG--12 (4.9%), cardiac valve implantation--14 (5.7), heart transplantation--4 (1.6%) and aortic aneurysm--21 (8.5%). Age distribution of patients with AKI revealed that most numerous group had 71-80 years. The most of patients (95.9%) with AKI were treated with hemodialysis. The mortality rate in the study group was very high (69.5%). Recovery of renal function was observed in 39 (27.3%) of patients. Signs of kidney disease before AKI was noted in 116 (47.2%) of patients. Patients with severe cardiovascular complications and AKI had high mortality rate instead of performed hemodialysis treatment.

This review provides updates on acute conditions affecting the periodontal tissues, including abscesses in the periodontium, necrotizing periodontal diseases and other acute conditions that cause gingival lesions with acute presentation, such as infectious processes not associated with oral bacterial biofilms, mucocutaneous disorders and traumatic and allergic lesions. A periodontal abscess is clinically important because it is a relatively frequent dental emergency, it can compromise the periodontal prognosis of the affected tooth and bacteria within the abscess can spread and cause infections in other body sites. Different types of abscesses have been identified, mainly classified by their etiology, and there are clear differences between those affecting a pre-existing periodontal pocket and those affecting healthy sites. Therapy for this acute condition consists of drainage and tissue debridement, while an evaluation of the need for systemic antimicrobial therapy will be made for each case, based on local and systemic factors. The definitive treatment of the pre-existing condition should be accomplished after the acute phase is controlled. Necrotizing periodontal diseases present three typical clinical features: papilla necrosis, gingival bleeding and pain. Although the prevalence of these diseases is not high, their importance is clear because they represent the most severe conditions associated with the dental biofilm, with very rapid tissue destruction. In addition to bacteria, the etiology of necrotizing periodontal disease includes numerous factors that alter the host response and predispose to these diseases, namely HIV infection, malnutrition, stress or tobacco smoking. The treatment consists of superficial debridement, careful mechanical oral hygiene, rinsing with chlorhexidine and daily re-evaluation. Systemic antimicrobials may be used adjunctively in severe cases or in nonresponding conditions, being the first option metronidazole. Once the acute

Acute vaso-occlusive crisis (VOC) is a hallmark of sickle cell disease (SCD). Multiple complex pathophysiological processes can result in pain during a VOC. Despite significant improvements in the understanding and management of SCD, little progress has been made in the management of pain in SCD, although new treatments are being explored. Opioids and non-steroidal anti-inflammatory drugs (NSAIDs) remain the mainstay of treatment of VOC pain, but new classes of drugs are being tested to prevent and treat acute pain. Advancements in the understanding of the pathophysiology of SCD and pain and the pharmacogenomics of opioids have yet to be effectively utilized in the management of VOC. Opioid tolerance and opioid-induced hyperalgesia are significant problems associated with the long-term use of opioids, and better strategies for chronic pain therapy are needed. This report reviews the mechanisms of pain associated with acute VOC, describes the current management of VOC, and describes some of the new therapies under evaluation for the management of acute VOC in SCD.

Stroke is a significant cause of morbidity and mortality in patients with homozygous sickle cell disease (SCD). A specific large-vessel vasculopathy is often responsible for both haemorrhagic and ischaemic strokes in patients with SCD. Although intravenous thrombolysis has been considered as a therapeutic option for acute ischaemic strokes in SCD, its use remains debated because of an increased risk of spontaneous intracranial haemorrhage reported in this disease. This risk of haemorrhage is mainly supported by the presence of a Moyamoya syndrome often associated with the specific vasculopathy in patients with homozygous SCD. We report two cases of patients with homozygous SCD treated with intravenous thrombolysis for an acute ischaemic stroke without haemorrhagic transformation. Our cases suggest that reperfusion strategy in acute ischaemic stroke in patients with homozygous SCD can be considered once associated Moyamoya syndrome has been ruled out. An international registry would be of interest as these situations are rare. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017. All rights reserved.

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

2017-08-01

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

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

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.

Children are vulnerable to diet inadequacies, which may affect immune function. Our objective was to determine if a follow-up formula (FUF) containing DHA, the prebiotics PDX and GOS, and yeast β-glucan affects incidence of respiratory infections and diarrheal disease in healthy children. In a double-blind, randomized, controlled, prospective trial, 3-4 year old children were fed 3 servings per day of either a FUF with 25 mg DHA, 1.2 g PDX/GOS, and 8.7 mg yeast β-glucan per serving or an unfortified, cow's milk-based beverage (control) for 28 weeks. Fecal and blood samples were collected to assess immune markers and iron/zinc status. Incidence of acute respiratory infections (ARI), diarrheal disease, and antibiotic treatment were obtained from medical records. The FUF group had fewer episodes and shorter duration of ARI (mean days [SE]; control = 4.3 [0.2]; FUF = 3.5 [0.2]; P = .007), less antibiotic use (n [%]; control = 21 [14%]; FUF = 8 [5%]; P = .01), and fewer missed days of day care due to illness. No diarrheal disease was diagnosed in either group. The FUF group had higher interleukin-10 and white blood cell count at the end of the study. There were no differences in hemoglobin, serum ferritin and zinc, or fecal secretory immunoglobulin A. Daily consumption of a FUF was associated with fewer episodes and shorter duration of ARI, as well as less antibiotic use. The children who consumed the FUF had increased interleukin-10 and white blood cells, suggesting an antiinflammatory mechanism and/or an increase of effector immune cells.

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 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.

Surveillance for acute flaccid paralysis (AFP) is a fundamental cornerstone of the global polio eradication initiative (GPEI). Active surveillance (with visits to health facilities) is a critical strategy of AFP surveillance systems for highly sensitive and timely detection of cases. Because of the extensive resources devoted to AFP surveillance, multiple opportunities exist for additional diseases to be added using GPEI assets, particularly because there is generally 1 district officer responsible for all disease surveillance. For this reason, integrated surveillance has become a standard practice in many countries, ranging from adding surveillance for measles and rubella to integrated disease surveillance for outbreak-prone diseases (integrated disease surveillance and response). This report outlines the current level of disease surveillance integration in 3 countries (Nepal, India, and Nigeria) and proposes that resources continue for long-term maintenance in resource-poor countries of AFP surveillance as a platform for surveillance of vaccine-preventable diseases and other outbreak-prone diseases. © The Author 2017.

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.

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.

Tocilizumab-Induced Acute Liver Injury in Adult Onset Still’s Disease

Directory of Open Access Journals (Sweden)

Michael Drepper

2013-01-01

Full Text Available Background. Tocilizumab, a monoclonal humanized anti-IL-6 receptor antibody, is used in treatment of refractory adult onset Still’s disease (AOSD. Mild to moderate liver enzyme elevation is a well-known side effect, but severe liver injury has only been reported in 3 cases in the literature. Case. A young female suffering from corticoid and methotrexate refractory AOSD was treated by tocilizumab. After 19 months of consecutive treatment, she developed acute severe liver injury. Liver biopsy showed extensive hepatocellular necrosis with ballooned hepatocytes, highly suggestive of drug-induced liver injury. No other relevant drug exposure beside tocilizumab was recorded. She recovered totally after treatment discontinuation and an initial 3-day course of intravenous N-acetylcysteine with normalization of liver function tests after 6 weeks. Conclusion. Acute severe hepatitis can be associated with tocilizumab as documented in this case. Careful monitoring of liver function tests is warranted during tocilizumab treatment.

The effect of air pollution episodes (sulfur dioxide and dust) on the morbidity and mortality of a group of people suffering from upper respiratory disease and cardiovascular disease was studied by examining air monitoring data and health statistics (ambulance service records and death certificates) for the city of Lodz. During the month of January in 1971, when the atmospheric pollution reached a 7-year peak, ambulance station statistics revealed the incidnce of acute cardiovascular and respiratory diseases to be at a maximum. The number of deaths from these diseases reached a maximum of 18 on the first day of the episode; on subsequent days, however, the mortalities returned to average.

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

Directory of Open Access Journals (Sweden)

Olivia Meira Dias

2014-01-01

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

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.

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

Full Text Available Introduction:Food-borne diseases are the widespread problems worldwide. Campylobacter species are the most important pathogens causing gastroenteritis which is generally transmitted through the food with animal origin. The aim of this study was to identify the Campylobacter spp. in diarrheal outbreaks in food-borne diseases at country level. Methods:This cross-sectional study carried out in spring and summer, 2015. In total, 305 swabs from diarrheal stool samples of 102 food-borne outbreaks were collected in various provinces of Iran. All samples were examined for the presence and growth of Campylobacter spp. The descriptive analysis, chi-square test and SPSS v.21 software were used for the analysis of results. Results:From the total of 102 foodborne outbreaks, Zanjan Province with 24 outbreaks (24.5% and Yazd Province with 70 samples of diarrhea (23% included the most reported cases. Out of 305 tested samples, 119 (39% were from food, 35 (11.5% from water and 151 (41.5% from unknown sources (p <0.001.  Two outbreaks in Yazd Province including three stool samples contained Campylobacter coli. Typical symptoms included diarrhea (30.9%, abdominal cramps (68.5%, fever (31.8%, headache (42.3%, diarrhea (5.2%, nausea (62.3% and vomiting (64.9%. Conclusion:Results from this study showed that C. coli was responsible for diarrhea rather than C. jejuni.

Authors analyzed the distribution of diseases and compared ultrasonographic conclusions with confirmed diagnoses of emergency abdominal ultrasonographies in acute abdominal conditions. We evaluated the role of emergency abdominal ultrasonography especially in the decision of emergency operation. In one hundred and forty five patients, emergent abdominal ultrasonography was performed within on admission. We compared the sonographic conclusion with postoperative pathology and analyzed the diagnoses of medically treated diseases. Twenty-eight patients under vent surgery and 117 patients were treated conservatively. Among the surgically treated patients, 19 patients (70.4%) were correctly diagnosed by preoperative ultrasonography.These included acute appendicitis (N = 8), acute cholecystitis (n = 7), ovarian cyst torsion (n = 2), and liver abscess (n = 1). Correct preoperative diagnosis was not made in 9 patients, including acute appendicitis (n = 4),peritonitis due to bowel perforation (n = 2), ectopic pregnancy (n = 1), colonic diverticulitis (n = 1 ) and pelvic inflammatory disease (n = 1 ). Clinical follow up was possible in 50 patients among the non-operative patient group, and the clinical diagnoses were chronic liver disease (n = 14), acute pyelonephritis (n = 10), and biliary stone (n = 10). Emergent ultrasonography plays an important role in acute abdominal conditions by supporting the differential diagnosis of medical and surgical disease

Severity of acute vascular illness may have changed in the last decades due to improvements in primary and secondary prevention. Population-based data on the severity of acute ischemic cerebrovascular disease are sparse. We aimed to examine incidence, characteristics and severity of acute ischemic cerebrovascular disease in a well-defined population. All patients admitted with transient ischemic attack (TIA) or acute ischemic stroke from March 1, 2007, to February 29, 2008, with residence in the Aarhus area, were included. Incidence rates and characteristics of TIA and ischemic stroke were compared. TIA accounted for 30%, TIA and minor stroke combined for 65% of all acute ischemic cerebrovascular events. Age-adjusted incidence rates of TIA and ischemic stroke were 72.2/100,000 and 129.5/100,000 person-years, respectively. TIA patients were younger than stroke patients (66.3 vs. 72.7 years; p TIA and stroke patients share many characteristics; however, TIA patients are younger and have fewer manifestations of atherosclerotic diseases, indicating a high potential for secondary prevention.

2017-10-01

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

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

Directory of Open Access Journals (Sweden)

2013-01-01

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

The lack of safe water and sanitation contributes to the rampancy of diarrhea in many developing countries. This study describes the design of a cluster-randomized trial in Idiofa, the Democratic Republic of the Congo, seeking evidence of the impact of improved sanitation on diarrhea for children under four. Of the 276 quartiers, 18 quartiers were randomly allocated to the intervention or control arm. Seven hundred and-twenty households were sampled and the youngest under-four child in each household was registered for this study. The primary endpoint of the study is diarrheal incidence, prevalence and duration in children under five. Material subsidies will be provided only to the households who complete pit digging plus superstructure and roof construction, regardless of their income level. This study employs a Sanitation Calendar so that the mother of each household can record the diarrheal episodes of her under-four child on a daily basis. The diary enables examination of the effect of the sanitation intervention on diarrhea duration and also resolves the limitation of the small number of clusters in the trial. In addition, the project will be monitored through the 'Sanitation Map', on which all households in the study area, including both the control and intervention arms, are registered. To avoid information bias or courtesy bias, photos will be taken of the latrine during the household visit, and a supervisor will determine well-equipped latrine uptake based on the photos. This reduces the possibility of recall bias and under- or over-estimation of diarrhea, which was the main limitation of previous studies. The study was approved by the Institutional Review Board of the School of Public Health, Kinshasa University (ESP/CE/040/15; April 13, 2015) and registered as an International Standard Randomized Controlled Trial (ISRCTN: 10,419,317) on March 13, 2015.

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.

Acute abdominal pain is a common clinical condition. Clinical signs and symptoms can be difficult to interpret, and diagnostic imaging may help to identify intra-abdominal disease. Conventional X-ray, ultrasound (US) and computed tomography (CT) of the abdomen vary in usability between common surgical causes of acute abdominal pain. Overall, conventional X-ray cannot confidently diagnose or rule out disease. US and CT are equally trustworthy for most diseases. US with subsequent CT may enhance diagnostic precision. Magnetic resonance seems promising for future use in acute abdominal imaging.

To monitor the incidence change of acute coronary heart events in the all-ages farmers in Panyu District, Guangzhou City during 1991-2001 and 2010-2011. The surveillance on the same defined population as that from the PRC-USA cooperative epidemiologic project on the cardiovascular and pulmonary diseases 30-year ago was carried out in Panyu, Guangzhou in 1991-2001 and 2010-2011. The crude incidence of acute coronary events and the age-standardized incidence rate were calculated by the year, gender and age, and standardized with the world standard population age distribution. Incidences at the two different periods were compared. The annual average changing rate of the incidence was obtained by the regression analysis methods. In the 11 consecutive years of 1991-2001, a upward trend on the incidence of acute coronary events among the farmers in women in Panyu District was found (P acute coronary events in the year of 2010-2011 was significantly higher than that in the year of 1991 to 2001 [34.06 per 100 000 (age-adjusted rate as 28.50 per 100 000) versus 16.14 per 100 000 (age-adjusted rate as 16.57 per 100 000), P acute coronary events in males was noticed in 75-79 age group, and in 80-84 age group in females. Comparing to the period of 1991-2001, the largest incidence increases appeared in the age groups of 35-39 and 75-79 years in males, while in the age groups of 50-54 and 65-69 years in females. Up to 47.37% (36/76) events occurred on the age group older than 75 years, raised by 40.44% comparing to that in 1991-2001 (33.73%, 56/166). The incidence of acute coronary events among farmers in Panyu District is at middle or low level of China but there is an increasing trend in acute coronary incidence from 1991 to 2011. Our results suggest that the prevention and treatment on acute coronary syndrome should be strengthened, and especially on the age group with the largest increase of disease incidence.

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.

A reduced risk of perforated diverticular disease among individuals with current statin exposure has been reported. The aim of the present study was to investigate whether statins reduce the risk of acute diverticular disease. A nation-wide population-based case-control study was performed, including 13,127 cases hospitalised during 2006-2010 with a first-time diagnosis of colonic diverticular disease, and 128,442 control subjects (matched for sex, age, county of residence and calendar year). Emergency surgery, assumed to be a proxy for complicated diverticulitis, was performed on 906 of the cases during the index admission, with 8818 matched controls. Statin exposure was classified as "current" or "former" if a statin prescription was last dispensed ≤ 125 days or >125 days before index date, respectively. The association between statin exposure and acute diverticular disease was investigated by conditional logistic regression, including models adjusting for country of birth, educational level, marital status, comorbidities, nonsteroidal anti-inflammatory drug/steroid exposure and healthcare utilisation. A total of 1959 cases (14.9%) and 16,456 controls (12.8%) were current statin users (crude OR 1.23 [95% CI 1.17-1.30]; fully adjusted OR 1.00 [0.94-1.06]). One hundred and thirty-two of the cases subjected to surgery (14.6%), and 1441 of the corresponding controls (16.3%) were current statin users (crude OR 0.89 [95% CI 0.73-1.08]; fully adjusted OR 0.70 [0.55-0.89]). The results do not indicate that statins affect the development of symptomatic diverticular disease in general. However, current statin use was associated with a reduced risk of emergency surgery for diverticular disease.

Wilson disease (WD) that manifests solely with acute and severe neurological damage in the absence of hepatic disease and Kayser-Fleischer ring of the cornea is rare and difficult to diagnose at the acute setting. This report describes unusual diffusion and proton spectroscopic magnetic resonance (MR) imaging findings in a 12-year-old boy with WD who presented with hemichorea and subnormal copper metabolism. The MR imaging findings of lactate accumulation, decrease of N-acerylaspartate/creatinine (NAA/Cr) ratio and markedly increased apparent diffusion coefficient (ADC) value of the asymmetrical edematous putaminal lesions in the early stage were suggestive of acute necrosis with anaerobic metabolism of glucose leading to poor clinical outcome at follow-up.

Acute pancreatitis is an inflammatory disorder of the pancreas that is responsible for significant morbidity and mortality. The inflammasome pathway has acquired significant relevance in the pathogenesis of many inflammatory disorders, but its role in patients with acute pancreatitis still awaits clarification. We performed a prospective study in which 27 patients with acute pancreatitis and 16 healthy controls were included. We isolated peripheral blood mononuclear cells (PBMCs) and we assessed the expression and activation of different inflammasomes as well as their association with the clinical course of the disease. Our results show that PBMCs from patients with acute pancreatitis have elevated expression of several components of the inflammasome complex, including the inflammasome-forming receptor absent in melanoma 2 (AIM2), early during the onset of the disease. Activation of the AIM2 or NLRP3 inflammasomes in PBMCs from patients with acute pancreatitis results in exacerbated IL-1β and IL-18 production compared with PBMCs from healthy controls. Furthermore, both AIM2 mRNA expression and AIM2-mediated production of IL-1β by PBMCs correlated with increased systemic inflammation in these patients. Last, AIM2 expression was further increased in those patients that developed transient or persistent organ failure (moderate or severe acute pancreatitis). Our data demonstrates that AIM2 inflammasome expression and activation is increased early during the course of acute pancreatitis, and suggests that AIM2 activation may affect systemic inflammation and organ failure in these patients.

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.

If invasive ventilation can be avoided by performing noninvasive mechanical ventilation (NIV) in patients with acute respiratory failure (ARF), the disease can be effectively managed. It is important to clarify the characteristics of patients with neuromuscular diseases in whom initial NIV is likely to be unsuccessful. We studied 27 patients in stable neuromuscular condition who initially received NIV to manage fatal ARF to identify differences in factors immediately before the onset of ARF among patients who receive continuous NIV support, patients who are switched from NIV to invasive ventilation, and patients in whom NIV is discontinued. Endpoints were evaluated 24 and 72 hours after the initiation of NIV. After 24 hours, all but 1 patient with amyotrophic lateral sclerosis (ALS) received continuous NIV support. 72 hours later, 5 patients were switched from NIV to invasive ventilation, and 5 patients continued to receive NIV support. 72 hours after the initiation of NIV, the proportion of patients with a diagnosis of ALS differed significantly among the three groups (P=0.039). NIV may be attempted to manage acute fatal respiratory failure associated with neuromuscular diseases, but clinicians should carefully manage the clinical course in patients with ALS.

Injections of lipopolysaccharide in animal models generate acute anterior uveitis (also known as endotoxin-induced uveitis), but the effects of lipopolysaccharide injection are unknown in humans. We describe an unusual case in which acute anterior uveitis was dramatically activated subsequent to botulinum toxin injection in a patient with Behçet's disease but the acute anterior uveitis was satisfactorily attenuated by infliximab. A 53-year-old Japanese man had normal ocular findings at his regularly scheduled appointment. He had been diagnosed as having incomplete-type Behçet's disease 11 years before. Three years after the diagnosis he was given systemic infusions of 5 mg/kg infliximab every 8 weeks and he had not experienced a uveitis attack for 8 years with no treatment other than infliximab. Two days after the eye examination, he received intracutaneous botulinum toxin injections to treat axillary hyperhidrosis on both sides. Three hours after the injections, he noted rapidly increasing floaters in his right eye. Four days after the injections, his right eye showed severe acute anterior uveitis with deteriorated aqueous flare and anterior vitreous opacity. He received his scheduled infliximab injection, and the right acute anterior uveitis immediately attenuated. Botulinum toxin may have clinical effects similar to those of lipopolysaccharide in endotoxin-induced uveitis models. To the best of our knowledge, this is the first report to suggest that botulinum toxin may trigger acute anterior uveitis, although the precise mechanism is still unclear.

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.

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.

Full Text Available Objective: To determine the type and frequency of predominant enteropathogens in acute diarrhea and their associated characteristics in children treated at Hospital Regional Lambayeque (HRL - Peru. Materials and methods: A cross-sectional analytical study was carried out in 70 fecal samples between March and May 2015. These samples were studied by coproculture and immunochromatography for the detection of enteropathogenic bacteria and viruses, respectively, while enteroparasites were sought by direct microscopic examination, Kinyoun staining method and ELISA for the detection of coproantigens (Entamoeba histolytica, Giardia lamblia and Cryptosporidium spp. Leukocyte count and chemical tests (Benedict, Thevenon and Sudan III were also performed for the functional study of the diarrheal disease. Results: In 48.6% of the samples, the infectious etiology of diarrhea was detected, prevailing the parasitic cause (25.8%, followed by the bacterial (17.1% and viral (5.8% ones. The most common enteropathogens were G. lamblia (18.6% and Salmonella enteritidis (10.0%. An association between greater than 100 fecal leukocytes per field and the bacterial etiology (p=0.027 was observed, while less than 10 fecal leukocytes per field (p=0.002 and a positive Sudam III test (p=0.003 were associated with the parasitic etiology. Conclusions: In more than half of the samples (51.4% the infectious etiology of diarrhea could not be proven, whereas Giardia lamblia was the most frequent cause of diarrhea in the studied population. However, it is necessary to implement more sensitive and specific techniques for the detection of a greater range of enteropathogens with which to improve the diagnosis and treatment of the disease

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

Glucocorticoids are central to effective therapy of acute graft-versus-host disease (GVHD). However, only about half of the patients respond to steroids in initial therapy. Based on postulated mechanisms for anti-inflammatory effectiveness, we explored genetic variations in glucocorticoid receptor, co-chaperone proteins, membrane transporters, inflammatory mediators, and variants in the T-cell receptor complex in hematopoietic cell transplant recipients with acute GVHD requiring treatment with steroids and their donors toward response at day 28 after initiation of therapy. A total of 300 recipient and donor samples were analyzed. Twenty-three SNPs in 17 genes affecting glucocorticoid pathways were included in the analysis. In multiple regression analysis, donor SNP rs3192177 in the ZAP70 gene (O.R. 2.8, 95% CI: 1.3-6.0, P=.008) and donor SNP rs34471628 in the DUSPI gene (O.R. 0.3, 95% CI: 0.1-1.0, P=.048) were significantly associated with complete or partial response. However, after adjustment for multiple testing, these SNPs did not remain statistically significant. Our results, on this small, exploratory, hypothesis generating analysis suggest that common genetic variation in glucocorticoid pathways may help identify subjects with differential response to glucocorticoids. This needs further assessment in larger datasets and if validated could help identify subjects for alternative treatments and design targeted treatments to overcome steroid resistance. © 2017 John Wiley & Sons A/S.

Safe domestic potable water supplies are urgently needed to reduce childhood diarrheal disease. In periurban neighborhoods in Cochabamba, Bolivia, we conducted a cluster randomized controlled trial to evaluate the efficacy of a household-level hollow fiber filter and/or behavior change communication (BCC) on water, sanitation, and hygiene (WASH) to reduce the diarrheal disease in children less than 5 years of age. In total, 952 households were followed for a period of 12 weeks post-distribution of the study interventions. Households using Sawyer PointONE filters had significantly less diarrheal disease compared with the control arm during the intervention period, which was shown by diarrheal prevalence ratios of 0.21 (95% confidence interval [95% CI] = 0.15–0.30) for the filter arm and 0.27 (95% CI = 0.22–0.34) for the filter and WASH BCC arm. A non-significant reduction in diarrhea prevalence was reported in the WASH BCC study arm households (0.71, 95% CI = 0.59–0.86). PMID:24865680

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 people with liver diseases. One of them is vitamin K administration, but it is not known whether it benefits or harms people with acute or chronic liver disease and upper gastrointestinal bleeding. This is an update of this Cochrane review. To assess the beneficial and harmful effects of vitamin K for people with acute or chronic liver disease and upper gastrointestinal bleeding. 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

Full Text Available Background: Shigellosis is endemic throughout the world and it is among the most common causes of bacterial diarrheal diseases. Antibiotic resistance of Shigella is becoming a progressive problem in world. The aim of this study was the survey of shigellosis frequency and determination of antibiotic resistance profile of isolated strains from infected children in Tehran. Material and Methods: This study conducted on 9131 patients with acute diarrheal disease. For isolation of Shigella spp. from stool samples, culture performed on different selective and differential media. After confirmation of bacteria by biochemical tests, susceptibility testing was done by disc diffusion method according to clinical and laboratory standards (CLSI recomendations. Results: Among 9131 stool samples, Shigella spp. was isolated from 90 cases. Shigella sonnei was the most common isolated species. 92/2 % of isolates were resistant to cotrimoxazole. In contrast, most of the Shigella spp. was founded to be sensitive to ciprofloxacin, imipenem and third-generation cephalosporins. Conclusion: Surveillance programs on antimicrobial resistance not only identify pathogenic bacterial species, by reporting data like serotyping, microorganisms incidence rates, and susceptibility to the antimicrobial agents currently used for treatment, but also contribute to monitoring the intervention strategies including removing organism from reservoirs.

Before the introduction of rotavirus vaccine in Egypt, information on the burden of disease and the circulating rotavirus genotypes is critical to monitor vaccine effectiveness. A cohort of 348 Egyptian children was followed from birth to 2 years of age with twice-weekly home visits to detect diarrheal illness. VP7 and VP4 genes were genotyped by reverse-transcription polymerase chain reaction and DNA sequencing. Forty percentage of children had rotavirus-associated diarrhea at least once by their second birthday. One hundred and twelve children experienced a single rotavirus diarrheal episodes (RDE) at a median age of 9 months; while 27 infants had their second RDE at a median age of 15 months and 1 infant had 3 RDE at the age of 2, 16 and 22 months. Of the 169 RDE, 82% could be assigned a G-type, while 58% had been identified a P-type. The most prevalent genotype was G2 (32%), followed by G1 (24%) and G9 (19%). G2P[4] rotavirus episodes were significantly associated with fever (P = 0.03) and vomiting (P = 0.06) when compared with other genotypes. G2 strains were the predominant genotype causing 50% of the second RDE while G9 represented 25% of the second RDE. Genotypes identified are similar to those detected globally except for absence of G4. Our finding that 75% of the second RDE were due to G2 and G9 indicates a possible reduction in natural protection afforded by these types compared with G1, where 90% of G1 cases did not experience a second xposure, indicating greater protection against recurrent symptomatic infection.

Few instruments capture symptoms that predict cardiac events in the short-term. This study examines the ability of the McSweeney Acute and Prodromal Myocardial Infarction Symptom Survey to predict acute cardiac events within 3 months of administration and to identify the prodromal symptoms most associated with short-term risk in women without known coronary heart disease. The McSweeney Acute and Prodromal Myocardial Infarction Symptom Survey was administered to 1,097 women referred to a cardiologist for initial coronary heart disease evaluation. Logistic regression models were used to examine prodromal symptoms individually and in combination to identify the subset of symptoms most predictive of an event within 3 months. Fifty-one women had an early cardiac event. In bivariate analyses, 4 of 30 prodromal symptoms were significantly associated with event occurrence within 90 days. In adjusted analyses, women reporting arm pain or discomfort and unusual fatigue were more likely (OR, 4.67; 95% CI, 2.08-10.48) to have a cardiac event than women reporting neither. The McSweeney Acute and Prodromal Myocardial Infarction Symptom Survey may assist in predicting short-term coronary heart disease events in women without known coronary heart disease.

Adaptation in Bacillus cereus: from stress to disease

Directory of Open Access Journals (Sweden)

Catherine Duport

2016-10-01

Full Text Available Bacillus cereus is a foodborne pathogen that causes diarrheal disease in humans. After ingestion B. cereus experiences in the human gastro-intestinal tract abiotic physical variables encountered in food, such as acidic pH in the stomach and changing oxygen conditions in the human intestine. B. cereus responds to environmental changing conditions (stress by reversibly adjusting its physiology to maximize resource utilization while maintaining structural and genetic integrity by repairing and minimizing damage to cellular infrastructure. As reviewed in this article, B. cereus adapts to acidic pH and changing oxygen conditions through diverse regulatory mechanisms and then exploits its metabolic flexibility to grow and produce enterotoxins. We then focus on the intricate link between metabolism, redox homeostasis and enterotoxins, which are recognized as important contributors of food-borne disease.

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.

Using data of the branch statistical reporting of the State Sanitary and Epidemiological Service in Sumy region and Sumy Regional State Laboratory of Veterinary Medicine, the incidence rate, modern risk factors for the development and spreading of acute infectious diarrheas were determined in the North-Eastern region of Ukraine. Under the current conditions incidence rate indices of acute intestinal infections and food toxicoinfections are within the range of 159.8-193.6 per 100 thousands. pop. Seasonal and epidemical rises are associated with a species of the agent. In the etiological structure of acute diarrheal infections there are dominated viruses, of food toxicoinfections--Klebsiellae pneumoniae, Staphylococcus aureus and Enterobacter cloacae (p < 0.05). Predictors of the complication of epidemiological situation of Shigella infections are the gain in the detection of bacterially contaminated samples of milk and dairy products (r = 0.75), for food toxicoinfections caused by Klebsiellae pneumoniae and Enterobacter cloacae--pastry with cream and cooking meat products (r = 0.64; r = 0.75). Epizootic situation in the region affects on the salmonellosis incidence rate of the population (r = 0.89). There were revealed correlations between the selection of E. coli bacteria from swabs taken from the enterprises of catering, in child care centers and the levels of incidence rates of salmonellosis, acute intestinal infections of unknown etiology (r = 0.59; r = 0.60). Timely detection and sanitation of Shigella carriers are a powerful instrument to reduce the incidence rate of shigellosis (r = 0.83).

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.

Full Text Available Gastroesophageal reflux disease (GERD is a common disease which can cause troublesome symptoms and affect quality of life. In addition to esophageal complications, GERD may also be a risk factor for extra-esophageal complications. Both GERD and coronary artery disease (CAD can cause chest pain and frequently co-exist. However, the association between GERD and acute myocardial infarction (AMI remain unclear. The purpose of the study was to compare the incidence of acute myocardial infarction in GERD patients with an age-, gender-, and comorbidity matched population free of GERD. We also examine the association of the risk of AMI and the use of acid suppressing agents in GERD patients.We identified patients with GERD from the Taiwan National Health Insurance Research Database. The study cohort comprised 54,422 newly diagnosed GERD patients; 269,572 randomly selected age-, gender-, comorbidity-matched subjects comprised the comparison cohort. Patients with any prior CAD, AMI or peripheral arterial disease were excluded. Incidence of new AMI was studied in both groups.A total 1,236 (0.5% of the patients from the control group and 371 (0.7% patients from the GERD group experienced AMI during a mean follow-up period of 3.3 years. Based on Cox proportional-hazard model analysis, GERD was independently associated with increased risk of developing AMI (hazard ratio (HR = 1.48; 95% confidence interval (CI: 1.31-1.66, P < 0.001. Within the GERD group, patients who were prescribed proton pump inhibitors (PPIs for more than one year had slightly decreased the risk of developing AMI, compared with those without taking PPIs (HR = 0.57; 95% CI: 0.31-1.04, P = 0.066.This large population-based study demonstrates an association between GERD and future development of AMI, however, PPIs use only achieved marginal significance in reducing the occurrence of AMI in GERD patients. Further prospective studies are needed to evaluate whether anti-reflux medication may

Approximately 10% of patients with acute pancreatitis (AP) progress to chronic pancreatitis. Little is known about the factors that affect recurrence of pancreatitis after an initial episode. We retrospectively investigated patients with AP, focusing on their outcomes and the predictors for disease progression. Between July 2003 and June 2015, we retrospectively enrolled first-time AP patients with medical records on disease etiology, severity (according to the Atlanta classifications), and recurrence of AP. Independent predictors of recurrent AP (RAP) and chronic pancreatitis were identified using the logistic regression model. Of the total 159 patients, 45 (28.3%) developed RAP, including two episodes of RAP in 19 patients, and 9 (5.7%) developed chronic pancreatitis. The median duration from the time of AP to the onset of RAP was 5.6 ± 2.3 months. RAP patients were identified as more common among patients with idiopathic first-time AP. The presence of severe ascites, pancreatic necrosis, and systemic complications was independent predictors of RAP in pediatric patients. Experiencing over two RAP episodes was the predictor for developing chronic pancreatitis. No influence of age or number of AP episodes was found on the occurrence of abdominal pain, pain severity, and the prevalence of any pain. Severity of first-time AP and idiopathic first-time AP are related to RAP. Recurrence increases risk for progression to chronic pancreatitis. The risk of recurrence increased with increasing numbers of AP episodes. Copyright © 2016 Elsevier Inc. All rights reserved.

Water Quality vs. Sanitation Accessibility: What is the most effective intervention point for preventing cholera in Dhaka, Bangladesh?

Science.gov (United States)

Majumder, M. S.; Gute, D.; Faruque, A. S.

2011-12-01

Every year, 3 to 5 million individuals contract cholera, an acute diarrheal infection that is caused by the ingestion of food or water containing the Vibrio cholerae bacterium. Because cholera is a waterborne disease, it can be transmitted quickly in environments with inadequate water and sanitation systems where infected waste can easily pollute drinking water. Today, Bangladesh continues to struggle with endemic cholera. Donor organizations address water and sanitation via localized initiatives, including the installation of community water collection sites (i.e. tubewells; water-boiling points; etc.). At this small-scale level, water quality and sanitation accessibility can be improved independently of one another, and when resources are limited, donors must invest in the most effective disease prevention options. This study used laboratory-confirmed cholera incidence data (2000-2009) collected by the International Centre of Diarrheal Disease Research, Bangladesh at their on-site hospital to compare the efficacy of interventions addressing water quality versus sanitation accessibility in Dhaka, Bangladesh. Data regarding use of sanitary latrines and boiling of drinking water were extracted from sequential patient interviews conducted at the Dhaka facility and used as surrogate variables for sanitation accessibility and water quality respectively. Our analysis indicates that boiling water is 10 times more effective at preventing cholera than the use of a sanitary latrine. This finding suggests that regulating water quality is perhaps more critical to cholera prevention than increasing sanitation accessibility in an urban environment like that of Dhaka. At present, WaterAid - one of Bangladesh's most significant water and sanitation donor organizations - invests the majority of its budget on improving sanitation accessibility. The World Health Organization and the United Nations Millennium Development Goals also prioritize sanitation accessibility. However, in

Molecular methods have been developed for the detection and quantification of Trypanosoma cruzi DNA in blood samples from patients with Chagas disease. However, aspects of sample processing necessary for quantitative real-time PCR (qPCR), such as the addition of guanidine hydrochloride to whole blood samples, may limit timely access to molecular diagnosis. We analysed 169 samples from serum and guanidine-EDTA blood (GEB) obtained from patients in acute and chronic phases of Chagas disease. We applied qPCR targeted to the satellite DNA region. Finally, we compared the parasite loads and cycle of threshold values of the qPCR. The results confirmed the usefulness of serum samples for the detection and quantification of parasite DNA in patients with Chagas disease, especially in the acute phase. However, the parasite loads detected in serum samples from patients in the chronic phase were lower than those detected in GEB samples. The epidemiological implications of the findings are herein discussed.

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.

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

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. Copyright © 2012 Elsevier España, S.L. y SEMICYUC. All rights reserved.

Acute alcohol-induced liver injury

Full Text Available Alcohol consumption is customary in most cultures and alcohol abuse is common worldwide. For example, more than 50% of Americans consume alcohol, with an estimated 23.1% of Americans participating in heavy and/or binge drinking at least once a month. A safe and effective therapy for alcoholic liver disease (ALD in humans is still elusive, despite significant advances in our understanding of how the disease is initiated and progresses. It is now clear that acute alcohol binges not only can be acutely toxic to the liver, but also can contribute to the chronicity of ALD. Potential mechanisms by which acute alcohol causes damage include steatosis, dysregulated immunity and inflammation and altered gut permeability. Recent interest in modeling acute alcohol exposure has yielded new insights into potential mechanisms of acute injury, that also may well be relevant for chronic ALD. Recent work by this group on the role of PAI-1 and fibrin metabolism in mediating acute alcohol-induced liver damage serve as an example of possible new targets that may be useful for alcohol abuse, be it acute or chronic.

Acute peritoneal dialysis (PD) is the preferred therapy for renal replacement in children with post-diarrheal hemolytic uremic syndrome (D+ HUS), but peritonitis remains a frequent complication of this procedure. We reviewed data from 149 patients with D+ HUS who had undergone acute PD with the aim of determining the prevalence and risk factors for the development of peritonitis. A total of 36 patients (24.2%) presented peritonitis. The median onset of peritonitis manifestations was 6 (range 2-18) days after the initiation of dialysis treatment, and Gram-positive microorganisms were the predominant bacterial type isolated (15/36 patients). The patients were divided into two groups: with or without peritonitis, respectively. Univariate analysis revealed that a longer duration of the oligoanuric period, more days of dialysis, catheter replacement, stay in the intensive care unit, and hypoalbuminemia were significantly associated to the development of peritonitis. The multivariate analysis, controlled by duration of PD, identified the following independent risk factors for peritonitis: catheter replacement [p = 0.037, odds ratio (OR) 1.33, 95% confidence interval (CI) 1.02-1.73], stay in intensive care unit (p = 0.0001, OR 2.62, 95% CI 1.65-4.19), and hypoalbuminemia (p = 0.0076, OR 1.45, 95% CI 1.10-1.91). Based on these findings, we conclude that the optimization of the aseptic technique during catheter manipulation and early nutritional support are targets for the prevention of peritonitis, especially in critically ill patients.

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

There are limited data on the epidemiology of acute respiratory failure necessitating mechanical ventilation in patients with severe chronic obstructive pulmonary disease (COPD). The prognosis of acute respiratory failure requiring invasive mechanical ventilation is believed to be grim in this population. The purpose of this study was to illustrate the epidemiologic characteristics and outcomes of patients with underlying severe COPD requiring mechanical ventilation.A retrospective study of patients admitted to a quaternary referral medical intensive care unit (ICU) between January 2008 and December 2012 with a diagnosis of severe COPD and requiring invasive mechanical ventilation for acute respiratory failure.We evaluated 670 patients with an established diagnosis of severe COPD requiring mechanical ventilation for acute respiratory failure of whom 47% were male with a mean age of 63.7 ± 12.4 years and Acute physiology and chronic health evaluation (APACHE) III score of 76.3 ± 27.2. Only seventy-nine (12%) were admitted with a COPD exacerbation, 27(4%) had acute respiratory distress syndrome (ARDS), 78 (12%) had pneumonia, 78 (12%) had sepsis, and 312 (47%) had other causes of respiratory failure, including pulmonary embolism, pneumothorax, etc. Eighteen percent of the patients received a trial of noninvasive positive pressure ventilation. The median duration of mechanical ventilation was 3 days (interquartile range IQR 2-7); the median duration for ICU length of stay (LOS) was 5 (IQR 2-9) days and the median duration of hospital LOS was 12 (IQR 7-22) days. The overall ICU mortality was 25%. Patients with COPD exacerbation had a shorter median duration of mechanical ventilation (2 vs 4 days; P = .04), ICU (3 vs 5 days; P = .01), and hospital stay (10 vs 13 days; P = .01). The ICU mortality (9% vs 27%; P respiratory failure. A 1-unit increase in the APACHE III score was associated with a 1% decrease and having an active cancer was associated

Sickle cell disease is characterized by chronic hemolytic anemia and vaso-occlusive painful crisis. The vascular occlusion in sickle cell disease is a complex process and accounts for the majority of the clinical manifestations of the disease. Abdominal pain is an important component of vaso-occlusive painful crisis and may mimic diseases such as acute appendicitis and cholecystitis. Acute pancreatitis is rarely included as a cause of abdominal pain in patients with sickle cell disease. When it occurs it may result form biliary obstruction, but in other instances it might be a consequence of microvessel occlusion causing ischemia. In this series we describe four cases of acute pancreatitis in patients with sickle cell disease apparently due to microvascular occlusion and ischemic injury to the pancreas. All patients responded to conservative management. Acute pancreatitis should be considered in the differential diagnosis of abdominal pain in patients with sickle cell disease.

A mind map for managing minimal residual disease in acute myeloid leukemia.

Science.gov (United States)

Benton, Christopher B; Ravandi, Farhad

2017-11-01

Advances in detecting traces of leukemia that were previously unidentifiable have increasingly led to the incorporation of information about residual disease into clinical decision making for patients with leukemia in both the postinduction and consolidation settings. This review discusses current concepts related to minimal residual disease (MRD), which is defined as submicroscopic disease detected during morphologic complete remission. The focus is on acute myeloid leukemia (AML). Basic methods for detecting MRD include flow cytometry, reverse transcription-polymerase chain reaction, and mutation analysis. Several studies using these assays have demonstrated prognostic implications based on MRD-positive vs MRD-negative status. As our understanding of the biological factors responsible for MRD in AML evolves, residual disease should be evaluated in the context of other prognostic markers. Current therapeutic options for managing MRD in AML are limited, and the clinical implications of a positive MRD test result can be significant. Regarding individual patients, an evidence-based approach must be applied while the institution- and assay-specific differences that currently exist are considered. Challenges associated with MRD assessment, such as the limited standardization of available assays and the paucity of effective agents to eradicate MRD, will need to be overcome before physicians who treat leukemia can use MRD as a tool for clinical management.

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

Before seeing a pediatrician, parents often look online to obtain child health information. We aimed to determine the influence of IUC (internet use regarding the reason for consultation) on their subjective information level, their assessment of acute diseases and the change in this assessment. Secondary objectives were to identify the most commonly used online resources and factors with an influence on IUC. This cross-sectional observational study was conducted at a general pediatric outpatient clinic located in Vienna, Austria. An anonymous, voluntary and 14-items-containing questionnaire served to gather all data. A total number of 500 questionnaires were collected. Of the parents attending the outpatient clinic, 21 % use the internet before the appointment (= IUC). Most common online resources utilized for this purpose are websites run by doctors (61.3 %), the outpatient clinic's homepage (56.3 %), Google (40 %), Wikipedia (32.5 %), health advisory services provided by doctors (28.7 %), health portals (21.3 %) and health forums and communities (18.8 %). The information level in terms of the reason for consultation is rated as good by 50.6 %, as average by 46.7 % and as insufficient by 2.7 % (internet users: 42.7 %, 55.3 %, 1.9 %). Acute diseases of the children are estimated to be mild by 58.4 %, to be moderate by 41.1 % and to be severe by 0.5 % (internet users: 54.9 %, 45.1 %, 0 %). After having used any source of information, this assessment is unchanged in 82.8 %, acute diseases are rated as more severe in 13.8 % and as less severe in 3.4 % (internet users: 79.2 %, 16.7 %, 4.2 %). Internet users and non-users do not differ with respect to their information level (p = 0.178), the assessment of acute diseases (p = 0.691) and the change in this assessment (p = 0.999). A higher education level of parents (mothers: p = 0.025, fathers: p = 0.037), a young age of their children (p = 0.012) and acute diseases of

2017-01-01

Full Text Available Background: Diarrhoea remains the second most common cause of death among children below 5 years globally. Among various enteric pathogens, rotavirus appears to be the most important aetiological agent of acute gastroenteritis in infants and young children. Increased understanding of epidemiology of rotavirus infections is needed to improve the vaccine efficacy. Aim: This study aims to determine prevalence rotavirus infection and prevalent circulating strains of rotavirus in and around Pune. Setting and Design: Prospective hospital-based study. The study was approved by Institutional Ethical Committee. Materials and Methods: Stool samples (n = 100 were collected from children aged <5 years, hospitalised for acute diarrhoea in paediatric ward at a tertiary care hospital. Samples were subjected for rotavirus antigen capture ELISA. The viral RNA was subjected to multiplex reverse transcription polymerase chain reaction to amplify VP7 genotypes G1–G4, G8–G10 and G12 and VP4 genotypes P[4], P[6], P[8], P[9], P[10] and P[11]. Nontypable rotavirus strains were sequenced. Results: About 35% stool samples were positive for rotavirus antigen by ELISA. G9P[4] (28.6% was found to be the most prevalent rotavirus strain. The detection of emerging strain G12P[6] (14.3% and rare reassortant strain G9P[4] was the significant finding. Conclusion: Genotypes found in circulation are not present in the currently used vaccine. Thus, an emergence of newer genotypes over a period calls for the continued surveillance and genomic characterisation of rotaviruses to improve the vaccine efficacy.

The role of acute arterial hypertension in acute pulmonary edema (APE) as an associated or triggering phenomenon has been poorly investigated and is relevant to patient management. This was a prospective observational study of clinical, electrocardiographic, and echocardiographic characteristics of patients with APE. Potential triggers, including acute coronary syndrome (ACS), rapid atrial fibrillation (AF) (≥ 120 bpm in AF), fever > 38°C or volume overload, isolated acute hypertension (systolic blood pressure ≥ 170 mm Hg), and unknown factors were investigated. There were 742 patients, 578 with coronary artery disease (78%), 116 with valvular heart disease or cardiomyopathy (16%), and 47 without identifiable heart disease (6%). ACS was present in 482 (65%) patients (silent in 154 of them), AF was present in 76 (10%) patients, fever/volume overload was present in 62 (8%) patients, acute hypertension was present in 50 (7%) patients, and no apparent trigger was seen in 72 (10%) patients. Admission hypertension occurred in 260 patients (35%): 155 (60%) with ACS (silent in 49 [32%]), 36 (14%) with AF, 19 (7%) with fever/volume overload, and 59 (19%) as an isolated trigger. Similar results were obtained when analyzing patients using coronary angiography (467 patients [63%]). Acute hypertension was present more frequently in patients with severe hypoventilation (arterial Pco 2 > 60 mm Hg) than in those without (57% vs 29%; P acute hypertension is often present but mainly as an associated/reactive phenomenon and seems favoured by severe hypoventilation. Silent myocardial ischemia/necrosis deserves systematic investigation because it is not rare that it may be the underlying cause of APE. Copyright © 2016 Canadian Cardiovascular Society.

Full Text Available Wouter H van Geffen,1,2 Huib AM Kerstjens2 1Department of Respiratory Medicine, Medical Centre Leeuwarden, Leeuwarden, the Netherlands; 2Department of Pulmonary Diseases, University of Groningen, University Medical Center Groningen, Groningen, the Netherlands Background: Static hyperinflation is known to be increased during moderate acute exacerbations of chronic obstructive pulmonary disease (COPD (AECOPD, but few data exist in patients with severe exacerbations of COPD. The role of dynamic hyperinflation during exacerbations is unclear. Methods: In a prospective, observational cohort study, we recruited patients admitted to hospital for AECOPD. The following measurements were performed upon admission and again after resolution (stable state at least 42 days later: inspiratory capacity (IC, body plethysmography, dynamic hyperinflation by metronome-paced IC measurement, health-related quality of life and dyspnea. Results: Forty COPD patients were included of whom 28 attended follow-up. The IC was low at admission (2.05±0.11 L and increased again during resolution by 15.6%±23.1% or 0.28±0.08 L (mean ± standard error of the mean, p<0.01. Testing of metronome-paced changes in IC was feasible, and it decreased by 0.74±0.06 L at admission, similarly to at stable state. Clinical COPD Questionnaire score was 3.7±0.2 at admission and improved by 1.7±0.2 points (p<0.01, and the Borg dyspnea score improved by 2.2±0.5 points from 4.4±0.4 at admission (p<0.01. Conclusion: Static hyperinflation is increased during severe AECOPD requiring hospitalization compared with stable state. We could measure metronome-paced dynamic hyperinflation during severe AECOPD but found no increase.

To compare the diagnostic and prognostic value of mid-regional pro-ANP (MR-proANP) and N-terminal pro-B-type natriuretic peptide (NT-proBNP) in patients with acute dyspnea. MR-proANP and NT-proBNP were measured with commercial immunoassays at hospital admission (n = 313), on day 2 (n = 234), and before discharge (n = 91) and compared for diagnosing acute heart failure (HF; n = 143) and to predict mortality among patients with acute HF and acute exacerbation of chronic obstructive pulmonary disease (AECOPD; n = 84) separately. The correlation coefficient between MR-proANP and NT-proBNP was 0.89 (p < 0.001) and the receiver-operating area under the curve was 0.85 (95% CI 0.81-0.89) for MR-proANP and 0.86 (0.82-0.90) for NT-proBNP to diagnose acute HF. During a median follow-up of 816 days, mortality rates were 46% in acute HF patients and 42% in AECOPD patients. After adjustment for other risk variables by multivariate Cox regression analysis, MR-proANP and NT-proBNP concentrations were associated with mortality in patients with acute HF, but only MR-proANP were associated with mortality among patients with AECOPD: hazard ratio ( ln MR-proANP) 1.98 (95% CI 1.17-3.34). MR-proANP and NT-proBNP concentrations provide similar diagnostic and prognostic information in patients with acute HF. In contrast to NT-proBNP, MR-proANP measurements also provided independent prognostic information in AECOPD patients.

Full Text Available Feline immunodeficiency virus (FIV infection in cats follows a disease course similar to HIV-1, including a short acute phase characterized by high viremia, and a prolonged asymptomatic phase characterized by low viremia and generalized immune dysfunction. CD4(+CD25(hiFoxP3(+ immunosuppressive regulatory T (Treg cells have been implicated as a possible cause of immune dysfunction during FIV and HIV-1 infection, as they are capable of modulating virus-specific and inflammatory immune responses. Additionally, the immunosuppressive capacity of feline Treg cells has been shown to be increased during FIV infection. We have previously shown that transient in vivo Treg cell depletion during asymptomatic FIV infection reveals FIV-specific immune responses suppressed by Treg cells. In this study, we sought to determine the immunological influence of Treg cells during acute FIV infection. We asked whether Treg cell depletion prior to infection with the highly pathogenic molecular clone FIV-C36 in cats could alter FIV pathogenesis. We report here that partial Treg cell depletion prior to FIV infection does not significantly change provirus, viremia, or CD4(+ T cell levels in blood and lymphoid tissues during the acute phase of disease. The effects of anti-CD25 mAb treatment are truncated in cats acutely infected with FIV-C36 as compared to chronically infected cats or FIV-naïve cats, as Treg cell levels were heightened in all treatment groups included in the study within two weeks post-FIV infection. Our findings suggest that the influence of Treg cell suppression during FIV pathogenesis is most prominent after Treg cells are activated in the environment of established FIV infection.

Oxidative stress plays a major role in the pathogenesis of a variety of acute and chronic diseases. Measurement of the oxidative stress-related end products may be performed, e.g. that of structural isomers of the physiological para-tyrosine, namely meta- and ortho-tyrosine, that are oxidized derivatives of phenylalanine. Recent data suggest that in sepsis, serum level of meta-tyrosine increases, which peaks on the 2(nd) and 3(rd) days (ptyrosine excretion correlated with both need of daily insulin dose and the insulin-glucose product in non-diabetic septic cases (ptyrosine excretion, urinary meta-tyrosine/para-tyrosine, urinary ortho-tyrosine/para-tyrosine and urinary (meta- + orthotyrosine)/ para-tyrosine proved to be markers of carbohydrate homeostasis. In a chronic rodent model, we tried to compensate the abnormal tyrosine isomers using para-tyrosine, the physiological amino acid. Rats were fed a standard high cholesterol-diet, and were given para-tyrosine or vehicle orally. High-cholesterol feeding lead to a significant increase in aortic wall meta-tyrosine content and a decreased vasorelaxation of the aorta to insulin and the glucagon-like peptide-1 analogue, liraglutide, that both could be prevented by administration of para-tyrosine. Concluding, these data suggest that meta- and ortho-tyrosine are potential markers of oxidative stress in acute diseases related to oxidative stress, and may also interfere with insulin action in septic humans. Competition of meta- and ortho-tyrosine by supplementation of para-tyrosine may exert a protective role in oxidative stress-related diseases.

One of the key factors of prognosis and risk stratification in patients with B-cell precursor acute lymphoblastic leukemia (BCP-ALL) is minimal residual disease (MRD). Identification of MRD on the day 15th is one of the most significant in prognosis of the disease. We compared data of a morphological and flow cytometry results of assessment of a bone marrow (BM) at the day 15th of induction chemotherapy in children with BCP-ALL.

Diarrheal diseases are a major cause of child mortality and one of the main causes of medical consultation for children in sub-Saharan countries. This paper attempts to determine the risk factors and neighborhood inequalities of diarrheal morbidity among under-5 children in selected countries in sub-Saharan Africa over the period 1990-2013. Data used come from the Demographic and Health Survey (DHS) waves conducted in Burkina Faso (1992-93, 1998-99, 2003, and 2010), Mali (1995, 2001, 2016, and 2012), Nigeria (1990, 1999, 2003, 2008, and 2013), and Niger (1992, 1998, 2006, and 2012). Bivariate analysis was performed to assess the association between the dependent variable and each of the independent variables. Multilevel logistic regression modelling was used to determine the fixed and random effects of the risk factors associated with diarrheal morbidity. The findings showed that the proportion of diarrheal morbidity among under-5 children varied considerably across the cohorts of birth from 10 to 35%. There were large variations in the proportion of diarrheal morbidity across countries. The proportions of diarrheal morbidity were higher in Niger compared with Burkina Faso, Mali, and Nigeria. The risk factors of diarrheal morbidity varied from one country to another, but the main factors included the child's age, size of the child at birth, the quality of the main floor material, mother's education and her occupation, type of toilet, and place of residence. The analysis shows an increasing trend of diarrheal inequalities according to DHS rounds. In Burkina Faso, the value of the intraclass correlation coefficient (ICC) was 0.04 for 1993 DHS and 0.09 in 2010 DHS; in Mali, the ICC increased from 0.04 in 1995 to 0.16 in 2012; in Nigeria, the ICC increased from 0.13 in 1990 to 0.19 in 2013; and in Niger, the ICC increased from 0.07 in 1992 to 0.11 in 2012. This suggests the need to fight against diarrheal diseases on both the local and community levels across villages.

Executive Summary In July 2010, the Medical Advisory Secretariat (MAS) began work on a Chronic Obstructive Pulmonary Disease (COPD) evidentiary framework, an evidence-based review of the literature surrounding treatment strategies for patients with COPD. This project emerged from a request by the Health System Strategy Division of the Ministry of Health and Long-Term Care that MAS provide them with an evidentiary platform on the effectiveness and cost-effectiveness of COPD interventions. After an initial review of health technology assessments and systematic reviews of COPD literature, and consultation with experts, MAS identified the following topics for analysis: vaccinations (influenza and pneumococcal), smoking cessation, multidisciplinary care, pulmonary rehabilitation, long-term oxygen therapy, noninvasive positive pressure ventilation for acute and chronic respiratory failure, hospital-at-home for acute exacerbations of COPD, and telehealth (including telemonitoring and telephone support). Evidence-based analyses were prepared for each of these topics. For each technology, an economic analysis was also completed where appropriate. In addition, a review of the qualitative literature on patient, caregiver, and provider perspectives on living and dying with COPD was conducted, as were reviews of the qualitative literature on each of the technologies included in these analyses. The Chronic Obstructive Pulmonary Disease Mega-Analysis series is made up of the following reports, which can be publicly accessed at the MAS website at: http://www.hqontario.ca/en/mas/mas_ohtas_mn.html.

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.

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

Acute epiploic appendagitis is a relatively rare disease that mimics a varied number of diseases. In this paper we report a 24-year-old male who presented with epiploic appendagitis that might have been misdiagnosed by physicians due to its equivocal presentation imitating more common acute abdominal conditions like acute appendicitis or acute diverticulitis depending on the site of the inflamed appendage. The clinical presentation, investigations findings and both conservative and surgical interventions of the patient are mentioned within the report. Radiological imaging like enhanced CT scan of the abdomen has an important role in differentiating acute epiploic appendigitis from other acute abdominal conditions along with the proper physical examination, thus promoting conservative management and avoiding surgery. However, failure of conservative management might lead to the surgical intervention. Copyright © 2018 The Authors. Published by Elsevier Ltd.. All rights reserved.

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.

Objective: To assess the clinical factors useful for the differentiation of acute arterial embolism from acute arterial thrombosis in patients with acute lower extremity ischemia. Methods: A total of 73 patients with acute arterial embolism or acute arterial thrombosis of lower extremity, who were admitted to the hospital during the period from May 2005 to June 2010, were enrolled in the study. Depending on the DSA findings, the patients were divided into arterial embolism group (n=52) and arterial thrombosis group (n=21). The clinical data, including general information, the onset of the disease, the obstructed sites, the condition of the diseased limb, the clinical manifestations and the severity of ischemia, were retrospectively analyzed and compared between the two groups. Results: The acute arterial embolism occurred usually on the iliofemoral artery (χ 2 =5.44, P 2 =4.15, P 2 =9.42, P 2 =18.10, P 2 =10.01, P 2 =5.44, P 2 =12.37, P 2 =7.96, P = 8.18, P 2 =14.00, P 2 =4.24, P<0.05) was only seen in patients with acute arterial embolism. Conclusion: The clinical factors helpful for differentiating acute arterial embolism from acute arterial thrombosis include: clinical manifestations (dyskinesia, impaired sensation and peripheral pulse condition of the healthy limb), the obstructed sites, the history of intermittent claudication and previous arterial embolism, the severity of ischemia, and the high-risk factors of the peripheral vascular disease (atrial fibrillation, hypertension, diabetes mellitus and smoking habit).

Objectives There are no guidelines on the use of echocardiography to detect cardiac manifestations of childhood-onset systemic lupus erythematosus (SLE). We quantify the prevalence of acute cardiac disease in youth with SLE, describe echocardiogram utilization at SLE diagnosis, and compare regional echocardiogram use with incident cardiac diagnoses. Methods Using the Clinformatics® DataMart (OptumInsight, Eden Prairie, MN) de-identified United States administrative database from 2000 to 2013, we identified youth ages 5-24 years with new-onset SLE (≥3 ICD-9 SLE codes 710.0, > 30 days apart) and determined the prevalence of diagnostic codes for pericardial disease, myocarditis, endocarditis, and valvular insufficiency. Multiple logistic regression was used to identify factors associated with echocardiography during the baseline period, up to one year before or six months after SLE diagnosis. We calculated a regional echocardiogram utilization index, which is the ratio of observed use over the mean predicted probability based on all available baseline characteristics. Spearman's rank correlation coefficient was used to evaluate the association between regional echocardiogram utilization indices and percentage of imaged youth diagnosed with their first cardiac manifestation following echocardiography. Results Among 699 youth with new-onset SLE, 18% had ≥ 1 diagnosis code for acute cardiac disease, of which valvular insufficiency and pericarditis were most common. Twenty-five percent of all youth underwent echocardiogram during the baseline period. Regional echocardiogram use was positively correlated with the percentage of imaged youth found to have cardiac disease (ρ = 0.71, p = 0.05). There was up to a five-fold difference in adjusted odds of baseline echocardiography between low- and high-utilizing regions (OR = 0.19, p = 0.007). Conclusion Nearly one-fifth of youth with new-onset SLE have acute cardiac manifestations; however, use of

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

Directory of Open Access Journals (Sweden)

Dimitrios Frangoulidis

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

Summary 1. Acute kidney injury (AKI) puts a major burden on health systems that may arise from multiple initiating insults, including ischemia-reperfusion injury, cardiovascular surgery, radio-contrast administration as well as sepsis. Similarly, the incidence and prevalence of chronic kidney disease (CKD) continues to increase with significant morbidity and mortality. Moreover, an increasing number of AKI patients survive to develop CKD and end-stage kidney disease (ESRD). 2. Although the mechanisms for development of AKI and progression of CKD remain poorly understood, initial impairment of oxygen balance is likely to constitute a common pathway, causing renal tissue hypoxia and ATP starvation that will in turn induce extracellular matrix production, collagen deposition and fibrosis. Thus, possible future strategies for one or both conditions may involve dopamine, loop-diuretics, inducible nitric oxide synthase inhibitors and atrial natriuretic peptide, substances that target kidney oxygen consumption and regulators of renal oxygenation such as nitric oxide and heme oxygenase-1.

Jetton, Jennifer G; Sorenson, Mark

2017-04-01

Both acute kidney injury (AKI) and chronic kidney disease (CKD) are seen more frequently in the neonatal intensive care unit (NICU) as advances in supportive care improve the survival of critically ill infants as well as those with severe, congenital kidney and urinary tract anomalies. Many aspects of the infant's care, including fluid balance, electrolyte and mineral homeostasis, acid-base balance, and growth and nutrition require close monitoring by and collaboration among neonatologists, nephrologists, dieticians, and pharmacologists. This educational review summarizes the therapies widely used for neonates with AKI and CKD. Use of these therapies is extrapolated from data in older children and adults or based on clinical experience and case series. There is a critical need for more research on the use of therapies in infants with kidney disease as well as for the development of drug delivery systems and preparations scaled more appropriately for these small patients.

The purpose of this study was to determine if the US-CRP values associated with periodontal disease are risk markers for Acute Myocardial Infarction (AMI) and to determine if the US-CRP levels associated with recent AMI are higher in patients with Periodontal disease. In order to meet the goal of the study, a case control study design was conducted. The analysis sample consisted of 401 adults (30 - 75 years old), living in Bogota D.C., Colombia, from the Hospital Universitario San Ignacio, the Faculty of Dentistry at the Pontificia Universidad Javeriana, and the Fundacion Cardio Infantil. Patients with current infections, antibiotic use in the last 3 months, periodontal treatment at least six months before the baseline of this study, mouth ulcerations caused by any type of prosthesis, candidiasis, stomatitis, or less than 7 teeth in mouth were excluded. Periodontal examination for the case group and the control group was conducted by three previously calibrated examiners. Periodontal disease was diagnosed by the presence of bleeding on probing and attachment loss. The Chronic Periodontitis diagnosis was confirmed with these clinical signs, according to the 1999 Armitage classification. The assessment of the US-CRP was performed using the IMMULITE method containing one monoclonal and one polyclonal anti-CRP antibody. This method provides a measurement range of 0.1 - 500 mg/L. Statistical analysis of variables was performed with OR and confidence intervals. A multivariate analysis was performed to determine the association between the US-CRP increase, periodontal disease and acute myocardial infarction, adjusting for smoking and other confounding factors identified in the analysis. The study population was constituted by 401 patients, 56.1% (225) males, with a mean age of 52.6. When groups were compared it was observed that, in those patients with AMI and chronic severe or moderate periodontitis, 24.2% had HDL-C values lower than 40 mg/dl, 78.8% had LDL-C values

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

Cell cycle arrest and the evolution of chronic kidney disease from acute kidney injury.

Canaud, Guillaume; Bonventre, Joseph V

2015-04-01

For several decades, acute kidney injury (AKI) was generally considered a reversible process leading to complete kidney recovery if the individual survived the acute illness. Recent evidence from epidemiologic studies and animal models, however, have highlighted that AKI can lead to the development of fibrosis and facilitate the progression of chronic renal failure. When kidney injury is mild and baseline function is normal, the repair process can be adaptive with few long-term consequences. When the injury is more severe, repeated, or to a kidney with underlying disease, the repair can be maladaptive and epithelial cell cycle arrest may play an important role in the development of fibrosis. Indeed, during the maladaptive repair after a renal insult, many tubular cells that are undergoing cell division spend a prolonged period in the G2/M phase of the cell cycle. These tubular cells recruit intracellular pathways leading to the synthesis and the secretion of profibrotic factors, which then act in a paracrine fashion on interstitial pericytes/fibroblasts to accelerate proliferation of these cells and production of interstitial matrix. Thus, the tubule cells assume a senescent secretory phenotype. Characteristic features of these cells may represent new biomarkers of fibrosis progression and the G2/M-arrested cells may represent a new therapeutic target to prevent, delay or arrest progression of chronic kidney disease. Here, we summarize recent advances in our understanding of the biology of the cell cycle and how cell cycle arrest links AKI to chronic kidney disease. © The Author 2014.

Changing climates have been causing variations in the number of global ischemic heart disease and stroke incidences, and will continue to affect disease occurrence in the future. To project temperature-related mortality for acute ischemic heart disease, and ischemic and hemorrhagic stroke with concomitant climate warming. We estimated the exposure-response relationship between daily cause-specific mortality and daily mean temperature in Beijing. We utilized outputs from 31 downscaled climate models and two representative concentration pathways (RCPs) for the 2020s, 2050s, and 2080s. This strategy was used to estimate future net temperature along with heat- and cold-related deaths. The results for predicted temperature-related deaths were subsequently contrasted with the baseline period. In the 2080s, using the RCP8.5 and no population variation scenarios, the net total number of annual temperature-related deaths exhibited a median value of 637 (with a range across models of 434-874) for ischemic stroke; this is an increase of approximately 100% compared with the 1980s. The median number of projected annual temperature-related deaths was 660 (with a range across models of 580-745) for hemorrhagic stroke (virtually no change compared with the 1980s), and 1683 (with a range across models of 1351-2002) for acute ischemic heart disease (a slight increase of approximately 20% compared with the 1980s). In the 2080s, the monthly death projection for hemorrhagic stroke and acute ischemic heart disease showed that the largest absolute changes occurred in summer and winter while the largest absolute changes for ischemic stroke occurred in summer. We projected that the temperature-related mortality associated with ischemic stroke will increase dramatically due to climate warming. However, projected temperature-related mortality pertaining to acute ischemic heart disease and hemorrhagic stroke should remain relatively stable over time. Copyright © 2017 Elsevier Ltd.

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

The cell biology of disease: Acute promyelocytic leukemia, arsenic, and PML bodies.

Science.gov (United States)

de Thé, Hugues; Le Bras, Morgane; Lallemand-Breitenbach, Valérie

2012-07-09

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.

This paper assesses the value and outcome of combined surgical (mini-cholecystostomy) and radiologic stone extraction in high-risk patients with acute calculous gallbladder disease. Sixty-seven patients were treated over a 6-year period. Three were 37 women and 30 men (age range, 33-98 years; mean, 73 years). Fifty (74%) surgical procedures were performed under local anesthesia. Radiologic gallstone extraction was achieved in 49 patients (73%). Extra-corporeal shock wave lithotripsy was required in six patients to fragment large stones. Twelve patients (18%) also had bile duct stones, of which 8 (67%) were successfully cleared. There were 4 deaths (6%) within 30 days. Twelve cholecystectomies (18%) were performed between 3 and 19 weeks (mean, 9 weeks) after minicholecystostomy as a result of failed stone clearance. The long-term outcome for those patients whose gallstones were cleared are discussed

Despite the progress, which has been made in diagnosis and therapy of encephalitis and bacterial meningitis, these acute inflammatory diseases of the brain still display a certain amount of morbidity and mortality. History, physical examination, analysis of serum and cerebrospinal fluid and radiological examination are the mainstay for the diagnosis of these diseases. With respect to the acute inflammatory diseases of the brain computed tomography and magnetic resonance imaging fulfil three purposes: 1. They can be used to clarify the diagnosis and to rule out other diseases. 2. They can identify the focus from which a bacterial meningitis can evolve. 3. Complications like edema, cerebral vasculitis, septic sinus thrombosis, hydrocephalus or abscess can be visualized. If the diagnosis is made early, the possible complications are recognized in good time and the appropriate therapy is started immediately, then morbidity and mortality can be kept at a minimum.

[German] Die bakterielle Meningitis und die Enzephalitis sind akut-entzuendliche Hirnerkrankungen, die trotz aller Fortschritte in der Diagnostik und Therapie mit einer nicht unerheblichen Morbiditaet und Mortalitaet behaftet sind. Die Anamnese, die koerperliche Untersuchung, die laborchemische Diagnostik von Blut und Liquor und die Bildgebung sind die wesentlichen Saeulen in der Diagnostik akut-entzuendlicher Hirnerkrankungen. Die Bildgebung, die mittels Computertomographie bzw. Kernspintomographie erfolgt, hat in diesem Zusammenhang 3 Aufgaben: 1. Sie kann dazu beitragen, die Diagnose zu sichern bzw. differentialdiagnostisch in Erwaegung zu ziehende Erkrankungen auszuschliessen oder nachzuweisen. 2. Sie kann bei der bakteriellen Meningitis entzuendliche Foci im Bereich der Nasennebenhoehlen, des Mastoids oder des Mittelohrs erkennen, die sofort operativ saniert werden muessen. 3.

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

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

Diagnosis of acute lung disease is a daily challenge for radiologists working in acute-care areas. It is generally based on the results of chest radiography performed under technically unfavorable conditions. Computed tomography (CT) is undoubtedly more accurate in these cases, but it cannot always be performed on critically ill patients who need continuous care. The use of thoracic ultrasonography (US) has recently been proposed for the study of acute lung disease. It can be carried out rapidly at the bedside and does not require any particularly sophisticated equipment. This report analyzes our experience with chest sonography as a supplement to chest radiography in an Emergency Radiology Unit. We performed chest sonography – as an adjunct to chest radiography – on 168 patients with acute chest pathology. Static and dynamic US signs were analyzed in light of radiographic findings and, when possible, CT. The use of chest US improved the authors' ability to provide confident diagnoses of acute disease of the chest and lungs. PMID:23397048

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

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

Full Text Available Childhood diarrheal diseases remain highly endemic in northeastern Brazil. The attributable fraction of all diarrheal diseases among children less than 2 years of age due to Escherichia coli was examined in a 2-year prospective study in two large urban centers of Brazil. Between May 1997 and June 1999, fecal E. coli isolates from 237 children with diarrhea (217 acute and 20 persistent cases and 231 children without diarrhea (controls attending two hospitals in Northeast Brazil were tested for their pattern of adherence to HEp-2 cells and for colony hybridization with DNA probes specific for the six pathotypes of diarrheagenic E. coli. Enteroinvasive E. coli, enterotoxigenic E. coli and enterohemorrhagic E. coli were not isolated from any children. Diffusely adherent E. coli (DAEC and enteroaggregative E. coli (EAEC were the most frequent isolates with similar frequencies from children with or without diarrhea. Atypical EPEC (EAF-negative strains were isolated with similiar frequency from both cases (5.5% and controls (5.6%. Enteropathogenic E. coli (typical EPEC strains, characterized by localized adherence pattern of adherence, hybridization with the EAF probe, and belonging to the classical O serogroups, were significantly associated with diarrhea (P = 0.03. These E. coli strains associated with diarrhea accounted for 9% of all children with diarrhea. Collectively, in Northeast Brazil, E. coli strains comprise a small proportion of severe diarrhea prevalence in children.

Diabetes impairs copper (Cu) regulation, causing elevated serum Cu and urinary Cu excretion in patients with established cardiovascular disease; it also causes cardiomyopathy and chronic cardiac impairment linked to defective Cu homeostasis in rats. However, the mechanisms that link impaired Cu regulation to cardiac dysfunction in diabetes are incompletely understood. Chronic treatment with triethylenetetramine (TETA), a Cu²⁺-selective chelator, improves cardiac function in diabetic patients, and in rats with heart disease; the latter displayed ∼3-fold elevations in free Cu²⁺ in the coronary effluent when TETA was infused into their coronary arteries. To further study the nature of defective cardiac Cu regulation in diabetes, we employed an isolated-perfused, working-heart model in which we infused micromolar doses of Cu²⁺ into the coronary arteries and measured acute effects on cardiac function in diabetic and non-diabetic-control rats. Infusion of CuCl₂ solutions caused acute dose-dependent cardiac dysfunction in normal hearts. Several measures of baseline cardiac function were impaired in diabetic hearts, and these defects were exacerbated by low-micromolar Cu²⁺ infusion. The response to infused Cu²⁺ was augmented in diabetic hearts, which became defective at lower infusion levels and underwent complete pump failure (cardiac output = 0 ml/min) more often (P acute effects on cardiac function of pathophysiological elevations in coronary Cu²⁺. The effects of Cu²⁺ infusion occur within minutes in both control and diabetic hearts, which suggests that they are not due to remodelling. Heightened sensitivity to the acute effects of small elevations in Cu²⁺ could contribute substantively to impaired cardiac function in patients with diabetes and is thus identified as a new mechanism of heart disease.

Neuropsychiatric symptoms of hepatitis C virus (HCV) infection and during peginterferon α therapy have been investigated in the chronic stage of the infection, but have not been described during the acute phase of the disease so far. We therefore evaluated anxiety and depression in patients with acute hepatitis C by the Hospital Anxiety and Depression Scale (HADS) within a clinical trial. Data were analysed from the German Hep-Net Acute HCV-III study. Anxiety and depression were characterized by an anxiety (HADS-A) and a depression subscale (HADS-D). More than eight points in each subscale were considered clinically relevant. Data were prospectively collected at baseline, end of treatment and at the end of the study. At baseline, a HADS-A above eight points was observed significantly more frequently than a HADS-D above eight points [n=23/103 (22%) vs. n=12/103 (12%); P=0.041].A pathological HADS-A or HADS-D score did not correlate with age, sex, IL28B genotype, the probable mode of infection, HCV genotype or severity of disease as investigated by alanine aminotransferase and bilirubin levels.Antiviral therapy did not influence anxiety as 12/50 (24%) of patients had HADS-A above 8 at the end of therapy. The proportion of patients with HADS-D above eight points increased from 12% at baseline to 24% (n=12/50) at the end of therapy (P=0.06). HADS results were not associated with lost to follow-up or sustained virological response rates. HADS data in acute HCV infection indicate that anxiety and depression do not correlate with severity of the disease, mode of acquisition, lost to follow-up and sustained virological response rates.
