    The 7-valent pneumococcal conjugate vaccine (PCV7) is reported to decrease the incidence of community-acquired pneumonia (CAP) in children. To determine the annual incidence of CAP before the introduction of PCV7, we counted the number of children hospitalized with CAP between 2008 and 2009 in Chiba City, Japan. We investigated serotype and multilocus sequence typing (MLST) for Streptococcus pneumoniae isolates in CAP cases. The annual incidence of hospitalized CAP in children aged pneumoniae was dominant in 14.7% and 0.8% of sputum and blood samples, respectively. The most common serotypes were 6B, 23F and 19F. The coverage rates of PCV7 were 66.7% and 80% in sputum samples and blood samples, respectively. MLST analysis revealed 37 sequence types. Furthermore, 54.1% of the sputum isolates and 40% of the blood isolate were related to international multidrug-resistant clones.

    Full Text Available Pneumonia is a leading cause of deaths in infants and young children in developing countries, including the Philippines. However, data at the community level remains limited. Our study aimed to estimate incidence and mortality rates and to evaluate risk factors and health-seeking behavior for childhood pneumonia. A household level interview survey was conducted in Biliran Island, the Philippines. Caregivers were interviewed using a semi-structured questionnaire to check if children had symptoms suggesting pneumonia-like episodes from June 2011 to May 2012. Of 3,327 households visited in total, 3,302 (99.2% agreed to participate, and 5,249 children less than 5 years of age were included in the study. Incidence rates of pneumonia-like episodes, severe pneumonia-like episodes, and pneumonia-associated mortality were 105, 61, and 0.9 per 1,000 person-years, respectively. History of asthma [hazard ratio (HR: 5.85, 95% confidence interval (CI: 4.83-7.08], low socioeconomic status (SES (HR: 1.11, 95% CI: 1.02-1.20, and long travel time to the healthcare facility estimated by cost distance analysis (HR: 1.32, 95% CI: 1.09-1.61 were significantly associated with the occurrence of pneumonia-like episodes by the Cox proportional hazards model. For severe pneumonia-like episodes, a history of asthma (HR: 8.39, 95% CI: 6.54-10.77 and low SES (HR: 1.30, 95% CI: 1.17-1.45 were significant risk factors. Children who had a long travel time to the hospital were less likely to seek hospital care (Odds ratio: 0.32, 95% CI: 0.19-0.54 when they experienced severe pneumonia-like episodes. Incidence of pediatric pneumonia-like episodes was associated with a history of asthma, SES, and the travel time to healthcare facilities. Travel time was also identified as a strong indicator for health-seeking behavior. Improved access to healthcare facilities is important for early and effective management. Further studies are warranted to understand the causal relationship

    Several studies examining the incidence of viral infection in childhood community-acquired pneumonia (CAP) utilizing polymerase chain reaction (PCR) or real-time PCR methods have been reported. We systematically searched Pubmed and Embase for studies reporting the incidence of respiratory viral infection in childhood CAP. The pooled incidences of viral infection were calculated with a random-effects model. Sources of heterogeneity were explored by subgroup analysis and a univariant metaregression analysis. We included 21 eligible reports in our study. We found significant heterogeneity on the incidence of viral infection in childhood CAP. The random effects pooled incidence was 57.4% (95% confidence interval (CI): 50.8-64.1). The pooled incidence of mixed infection was 29.3% (95%CI: 23.0-35.6) with considerable heterogeneity. The pooled incidence of mixed infection was 29.3% (95%CI: 23.0-35.6). Rhinovirus, respiratory syncytial virus (RSV) and bocavirus were found to be the three most common viruses in childhood CAP. We also demonstrated that respiratory viruses were detected in 76.1% of patients aged ≤ 1 year, 63.1% of patients aged 2-5 years and 27.9% of patients aged ≥ 6 years. We conclude that respiratory viruses are widely detected in paediatric patients with CAP by PCR or real-time PCR methods. More than half of viral infections are probably concurrent with bacterial infections. Rhinovirus, RSV and bocavirus are the three most frequent viruses identified in childhood CAP; the incidence of viral infection decreased with age.

    Full Text Available One of the major causes of mortality in children younger than 5 years old is acute lower respiratory tract infections (ALRI. ALRI clinical features are cough, tachypnea, fever, coryza, chest retraction, crackles and wheeze. Increased white blood cell count with left shift might happen in pneumonia. C-reactive protein (CRP and erythrocyte sedimentation rate (ESR might rise in children with respiratory tract infections. Vitamin A deficiency is associated with severe childhood infections. The effect of vitamin A supplementation in childhood pneumonia depends on the prevalence and the level of vitamin A deficiency in the population. Some studies confirmed that retinol levels were significantly higher after recovery from acute pneumonia compared to acute phase. But there were no significant association between serum retinol level and the clinical manifestation.

  5. Childhood Pneumonia Screener: a concept

    Full Text Available Childhood pneumonia continues to be the number one cause of death in children under five years of age in developing countries. In addition to mortality, pneumonia constitutes an enormous economic and social burden because late diagnosis is associated with high cost of treatment and often leads to chronic health problems. There are several bottlenecks in developing countries in the case flow of a child with lung infection: 1 recognising the symptoms as a reason to seek care, 2 getting the patient to a first-tier health facility, 3 scarcity of trained healthcare personnel who can diagnose the condition and its severity, 4 access to a second-tier facility in severe cases. These factors are commonly present in rural areas but even in more urban settings, access to a physician is often delayed. The Childhood Pneumonia Screener project aims at bridging the diagnostic gap using emerging technology. Mobile “smart” phone communication with several inexpensive dedicated sensors is proposed as a rapid data-collection and transmission unit that is connected to a central location where trained personnel assisted by sophisticated signal processing algorithms, evaluate the data and determine if the child is likely to have pneumonia and what the level and urgency of care should be.

    Full Text Available The recent series of reviews conducted within the Global Action Plan for Pneumonia and Diarrhoea (GAPPD addressed epidemiology of the two deadly diseases at the global and regional level; it also estimated the effectiveness of interventions, barriers to achieving high coverage and the main implications for health policy. The aim of this paper is to provide the estimates of childhood pneumonia at the country level. This should allow national policy–makers and stakeholders to implement proposed policies in the World Health Organization (WHO and UNICEF member countries.

  7. Infection by Mycoplasma pneumoniae and its importance as an etiological agent in childhood community-acquired pneumonias

    Full Text Available This manuscript reviewed the literature on infection by Mycoplasma pneumoniae with emphasis on etiological aspects of childhood community-acquired pneumonias. Bibliographical research was carried out from Pubmed Medline, MDConsult, HighWire, LILACS, and direct research over the past 10 years with the following keywords: Mycoplasma pneumoniae, pneumonia, and childhood. Fifty-four articles were selected. Mycoplasma pneumoniae has a high incidence in childhood. Clinical presentation includes respiratory and extrarespiratory symptoms. Mycoplasma pneumoniae lung infection can be confused with viral or bacterial pneumonia and is unresponsive to beta-lactams. In addition, co-infections have been reported. Mycoplasma pneumoniae infection occurs in all age groups, being less frequent and more severe in children under the age of five. Its incidence as a causal agent is high. Mycoplasma pneumoniae infections constitute 20%-40% of all community-acquired pneumonias; the severity is highly variable, and this condition may lead to severe sequelae. Mycoplasma pneumoniae frequency is underestimated in clinical practice because of the lack of specific features and a diagnosis that needs serology or PCR. Effective management of M. pneumoniae infections can usually be achieved with macrolides. In Brazil, epidemiological studies are needed in order to assess the incidence of this bacterium.

    Zinc supplementation has been consistently shown to reduce the incidence of childhood pneumonia, but its effect on the course of pneumonia when administered as an adjunct to antibiotic therapy is still unclear. Three trials published to date have shown mixed results, and a recent trial from India raises the possibility that zinc may be detrimental in some circumstances. Study sites and designs differ, particularly in the timing of zinc treatment and in determining recovery from pneumonia, which can explain the differences in study findings. Serum zinc concentrations are unreliable indicators of zinc status, particularly during acute infectious illnesses. Subgroup analyses, especially using serum zinc levels, must be cautioned against. Future studies are needed that are large enough to be sufficiently powered to accommodate larger treatment failure rates, an issue that ongoing trials will hopefully address.

    Pneumonia after videofluoroscopic swallow study (VFSS) is sometimes considered to be caused by aspiration during VFSS; however, to our knowledge, a relationship between these events has not been clearly investigated. The aim of this study was to assess the incidence of VFSS-related pneumonia and related factors. Overall, 696 VFSS cases were retrospectively reviewed. Cases in which blood culture was performed within 3 days after VFSS due to newly developed infectious signs were considered as post-VFSS infection cases. Pneumonia was suspected when there was some evidence of respiratory infectious signs in clinical, radiological, and laboratory findings. The underlying disease, clinical signs, and VFSS findings of the pneumonia group were assessed. Among 696 cases, pneumonia was diagnosed in 15 patients. The patients in the pneumonia group tended to be older and had higher aspiration rate on VFSS than those in the non-pneumonia group. In the pneumonia group, 2 patients showed no aspiration during VFSS. In 6 patients, pneumonia developed after massive aspiration of gastric content in 5 patients and inappropriate oral feeding with risk of aspiration before VFSS in 1 patient. Only 7 patients (1.0 %) were finally determined as having VFSS-related pneumonia. In conclusion, the 72-h incidence of VFSS-related pneumonia was 1.0 %. Old age and severity of swallowing difficulty are associated with occurrence of pneumonia.

    It is estimated that pneumonia is responsible for 15% of childhood deaths worldwide. Recent research has shown that hypoxia and malnutrition are strong predictors of mortality in children hospitalized for pneumonia. It is estimated that 15% of children under 5 who are hospitalized for pneumonia have hypoxaemia and that around 1.5 million children with severe pneumonia require oxygen treatment each year. We developed a deterministic compartmental model that links the care pathway to disease progression to assess the impact of introducing pulse oximetry as a prognostic tool to distinguish severe from non-severe pneumonia in under-5 year olds across 15 countries with the highest burden worldwide. We estimate that, assuming access to supplemental oxygen, pulse oximetry has the potential to avert up to 148,000 deaths if implemented across the 15 countries. By contrast, integrated management of childhood illness alone has a relatively small impact on mortality owing to its low sensitivity. Pulse oximetry can significantly increase the incidence of correctly treated severe cases as well as reduce the incidence of incorrect treatment with antibiotics. We also found that the combination of pulse oximetry with integrated management of childhood illness is highly cost-effective, with median estimates ranging from US$2.97 to $52.92 per disability-adjusted life year averted in the 15 countries analysed. This combination of substantial burden reduction and favourable cost-effectiveness makes pulse oximetry a promising candidate for improving the prognosis for children with pneumonia in resource-poor settings.

    Mycoplasma pneumoniae is a frequent cause of acute respiratory infections in both children and adults.It can cause pharyngitis, otitis, tracheobronchitis, or community-acquired pneumonia, but may also remain totally asymptomatic.Mycoplasma pneumoniae is an organism that reportedly has a strong relationship to asthma.The role of atypical bacterial infection in the pathogenesis of asthma is a subject of continuing debate. There is an increasing body of literature concerning the association between Mycoplasma pneumoniae ( M. pneumoniae) and asthma pathogenesis.Moreover, many studies investigating such a link have been uncontrolled and have provided conflicting evidence, in part due to the difficulty in accurately diagnosing infection with these atypical pathogens. Large, general population-based prospective studies are necessary to investigate the development of asthma induced by M. pneumoniae infection in humans. This manuscript will review the relationship between M.pneumoniae infection and childhood asthma.

    The impact of vaccination on non-bacteremic Haemophilus influenza pneumonia is difficult to appreciate, in the absence of proper microbiological documentation. It has certainly been largely underestimated. Vaccination has reduced the incidence of pneumococcal pneumonia. However, the increase of incidence of empyema due to nonvaccine serotypes was observed in several countries. The replacement of Prevenar 7 by Prevenar 13 portends a decrease in the occurrence of these infections, but, unfortunately, without eliminating them completely.

    This study aimed to assess the association between climate factors and the incidence of childhood pneumonia in Papua New Guinea quantitatively and to evaluate the variability of the effect size according to their geographic properties. The pneumonia incidence in children under five-year and meteorological factors were obtained from six areas, including monthly rainfall and the monthly average daily maximum temperatures during the period from 1997 to 2006 from national health surveillance data. A generalized linear model was applied to measure the effect size of local and regional climate factor. The pooled risk of pneumonia in children per every 10 mm increase of rainfall was 0.24% (95% confidence interval: -0.01%-0.50%), and risk per every 1 °C increase of the monthly mean of the maximum daily temperatures was 4.88% (95% CI: 1.57-8.30). Southern oscillation index and dipole mode index showed an overall negative effect on childhood pneumonia incidence, -0.57% and -4.30%, respectively, and the risk of pneumonia was higher in the dry season than in the rainy season (pooled effect: 12.08%). There was a variability in the relationship between climate factors and pneumonia which is assumed to reflect distribution of the determinants of and vulnerability to pneumonia in the community.

    Objective. To investigate the value of CT in complicated childhood pneumonia and its role in early intervention when chest radiography (CXR) is non-contributory. Materials and methods. Forty-two immunocompetent children, aged 1-11 years, admitted for community-acquired pneumonia from October 1997 to September 1999, had 42 contrast-enhanced CT scans and frontal chest radiographs on the same day, which were assessed independently. CT was performed when the patient remained unwell and the CXR images showed failure of resolution despite 7-10 days of antibiotics and/or drainage with urokinase therapy. Results. Compared to CT, CXR revealed suboptimal accuracy rates of lobar involvement (84%), chest tube placement (73%), fluid loculation (42%), abscess formation (40%) and bronchopleural fistulae (33%). It could not assess parenchymal or pleural complications such as cavitary necrosis, early abscess formation, empyemas or pericardial effusions. On the basis of the CT findings and poor clinical progress, 16 patients underwent surgical intervention with the aid of video-assisted thorascopic surgery (VATS). The CT features correlated well with surgical findings. Ten cases required pleural decortication while six with destructive or necrotic lung lesions had surgical resection. Debridement was difficult when the pleura had become thick and fibrotic. Streptococcus pneumoniae was the offending organism in 81% of cases. The right side was affected in 67% of cases. Conclusions. In complicated childhood pneumonia, CT is far superior to CXR in revealing pleural and parenchymal complications, which may require early surgical intervention. (orig.)

  16. mPneumonia: Development of an Innovative mHealth Application for Diagnosing and Treating Childhood Pneumonia and Other Childhood Illnesses in Low-Resource Settings.

    Directory of Open Access Journals (Sweden)

    Amy Sarah Ginsburg

    Full Text Available Pneumonia is the leading infectious cause of death in children worldwide. Each year, pneumonia kills an estimated 935,000 children under five years of age, with most of these deaths occurring in developing countries. The current approach for pneumonia diagnosis in low-resource settings--using the World Health Organization Integrated Management of Childhood Illness (IMCI paper-based protocols and relying on a health care provider's ability to manually count respiratory rate--has proven inadequate. Furthermore, hypoxemia--a diagnostic indicator of the presence and severity of pneumonia often associated with an increased risk of death--is not assessed because pulse oximetry is frequently not available in low-resource settings. In an effort to address childhood pneumonia mortality and improve frontline health care providers' ability to diagnose, classify, and manage pneumonia and other childhood illnesses, PATH collaborated with the University of Washington to develop "mPneumonia," an innovative mobile health application using an Android tablet. mPneumonia integrates a digital version of the IMCI algorithm with a software-based breath counter and a pediatric pulse oximeter. We conducted a design-stage usability field test of mPneumonia in Ghana, with the goal of creating a user-friendly diagnostic and management tool for childhood pneumonia and other childhood illnesses that would improve diagnostic accuracy and facilitate adherence by health care providers to established guidelines in low-resource settings. The results of the field test provided valuable information for understanding the usability and acceptability of mPneumonia among health care providers, and identifying approaches to iterate and improve. This critical feedback helped ascertain the common failure modes related to the user interface design, navigation, and accessibility of mPneumonia and the modifications required to improve user experience and create a tool aimed at decreasing

    Advocacy, policy, research and intervention efforts against childhood pneumonia have lagged behind other health issues, including malaria, measles and tuberculosis. Accelerating progress on the issue began in 2008, following decades of efforts by individuals and organizations to address the leading cause of childhood mortality and establish a global health network. This article traces the history of this network's formation and evolution to identify lessons for other global health issues. Through document review and interviews with current, former and potential network members, this case study identifies five distinct eras of activity against childhood pneumonia: a period of isolation (post WWII to 1984), the duration of WHO's Acute Respiratory Infections (ARI) Programme (1984-1995), Integrated Management of Childhood illness's (IMCI) early years (1995-2003), a brief period of network re-emergence (2003-2008) and recent accelerating progress (2008 on). Analysis of these eras reveals the critical importance of building a shared identity in order to form an effective network and take advantage of emerging opportunities. During the ARI era, an initial network formed around a relatively narrow shared identity focused on community-level care. The shift to IMCI led to the partial dissolution of this network, stalled progress on addressing pneumonia in communities and missed opportunities. Frustrated with lack of progress on the issue, actors began forming a network and shared identity that included a broad spectrum of those whose interests overlap with pneumonia. As the network coalesced and expanded, its members coordinated and collaborated on conducting and sharing research on severity and tractability, crafting comprehensive strategies and conducting advocacy. These network activities exerted indirect influence leading to increased attention, funding, policies and some implementation.

    Full Text Available Abstract Background Oxygen therapy is recommended for all of the 1.5 – 2.7 million young children who consult health services with hypoxemic pneumonia each year, and the many more with other serious conditions. However, oxygen supplies are intermittent throughout the developing world. Although oxygen is well established as a treatment for hypoxemic pneumonia, quantitative evidence for its effect is lacking. This review aims to assess the utility of oxygen systems as a method for reducing childhood mortality from pneumonia. Methods Aiming to improve priority setting methods, The Child Health and Nutrition Research Initiative (CHNRI has developed a common framework to score competing interventions into child health. That framework involves the assessment of 12 different criteria upon which interventions can be compared. This report follows the proposed framework, using a semi-systematic literature review and the results of a structured exercise gathering opinion from experts (leading basic scientists, international public health researchers, international policy makers and representatives of pharmaceutical companies, to assess and score each criterion as their “collective optimism” towards each, on a scale from 0 to 100%. Results A rough estimate from an analysis of the literature suggests that global strengthening of oxygen systems could save lives of up to 122,000 children from pneumonia annually. Following 12 CHNRI criteria, the experts expressed very high levels of optimism (over 80% for answerability, low development cost and low product cost; high levels of optimism (60-80% for low implementation cost, likelihood of efficacy, deliverability, acceptance to end users and health workers; and moderate levels of optimism (40-60% for impact on equity, affordability and sustainability. The median estimate of potential effectiveness of oxygen systems to reduce the overall childhood pneumonia mortality was ~20% (interquartile range: 10-35%, min

    The aim of this study was to illustrate the chest radiographs (CR) and CT imaging features and sequential findings of cavitary necrosis in complicated childhood pneumonia. Among 30 children admitted in the Pediatric Intensive Care Unit for persistent or progressive pneumonia, respiratory distress or sepsis despite adequate antibiotic therapy, a study group of 9 children (5 girls and 4 boys; mean age 4 years) who had the radiographic features and CT criteria for cavitary necrosis complicated pneumonia was identified. The pathogens identified were Streptococcus pneumoniae (n=4), Aspergillus (n=2), Legionella (n=1), and Staphylococcus aureus (n=1). Sequential CR and CT scans were retrospectively reviewed. Follow-up CR and CT were evaluated for persistent abnormalities. Chest radiographs showed consolidations in 8 of the 9 patients. On CT examination, cavitary necrosis was localized to 1 lobe in 2 patients and 7 patients showed multilobar or bilateral areas of cavitary necrosis. In 3 patients of 9, the cavitary necrosis was initially shown on CT and visualization by CR was delayed by a time span varying from 5 to 9 days. In all patients with cavities, a mean number of five cavities were seen on antero-posterior CR, contrasting with the multiple cavities seen on CT. Parapneumonic effusions were shown by CR in 3 patients and in 5 patients by CT. Bronchopleural fistulae were demonstrated by CT alone (n=3). No purulent pericarditis was demonstrated. The CT scan displayed persistent residual pneumatoceles of the left lower lobe in 2 patients. Computed tomography is able to define a more specific pattern of abnormalities than conventional CR in children with necrotizing pneumonia and allows an earlier diagnosis of this rapidly progressing condition. Lung necrosis and cavitation may also be associated with Aspergillus or Legionella pneumonia in the pediatric population. (orig.)

    The effect of temperature on childhood pneumonia in subtropical regions is largely unknown so far. This study examined the impact of temperature on childhood pneumonia in Brisbane, Australia. A quasi-Poisson generalized linear model combined with a distributed lag non-linear model was used to quantify the main effect of temperature on emergency department visits (EDVs) for childhood pneumonia in Brisbane from 2001 to 2010. The model residuals were checked to identify added effects due to heat waves or cold spells. Both high and low temperatures were associated with an increase in EDVs for childhood pneumonia. Children aged 2-5 years, and female children were particularly vulnerable to the impacts of heat and cold, and Indigenous children were sensitive to heat. Heat waves and cold spells had significant added effects on childhood pneumonia, and the magnitude of these effects increased with intensity and duration. There were changes over time in both the main and added effects of temperature on childhood pneumonia. Children, especially those female and Indigenous, should be particularly protected from extreme temperatures. Future development of early warning systems should take the change over time in the impact of temperature on children's health into account.

    Full Text Available Streptococcus pneumoniae is a leading cause of pneumonia worldwide. However, the burden of pneumococcal pneumonia among adults in low- and middle-income countries is not well described.Data from 2008-2012 was analyzed from two surveillance sites in Guatemala to describe the incidence of pneumococcal pneumonia in adults. A case of hospitalized pneumococcal pneumonia was defined as a positive pneumococcal urinary antigen test or blood culture in persons aged ≥ 18 years hospitalized with an acute respiratory infection (ARI.Among 1595 adults admitted with ARI, 1363 (82% had either urine testing (n = 1286 or blood culture (n = 338 performed. Of these, 188 (14% had pneumococcal pneumonia, including 173 detected by urine only, 8 by blood culture only, and 7 by both methods. Incidence rates increased with age, with the lowest rate among 18-24 year-olds (2.75/100,000 and the highest among ≥65 year-olds (31.3/100,000. The adjusted incidence of hospitalized pneumococcal pneumonia was 18.6/100,000 overall, with in-hospital mortality of 5%.An important burden of hospitalized pneumococcal pneumonia in adults was described, particularly for the elderly. However, even adjusted rates likely underestimate the true burden of pneumococcal pneumonia in the community. These data provide a baseline against which to measure the indirect effects of the 2013 introduction of the pneumococcal conjugate vaccine in children in Guatemala.

    This study examined socioeconomic differentials in cancer incidence rates during 2000-2005 among children aged 0-19 in the United States. The data on childhood cancers, which were classified by the International Classification of Childhood Cancer, Third Edition (ICCC-3), were obtained from the Surveillance, Epidemiology, and End Results program. The socioeconomic status of residential area at diagnosis was estimated by county-level poverty rate in Census 2000, i.e., percentage of persons in the county living below the national poverty thresholds. Counties were categorized as low-, medium-, and high-poverty areas when the poverty rates were poverty counties had lower age-adjusted incidence rates than low-poverty counties for total childhood cancers combined, central nervous system neoplasms (ICCC group III), neuroblastoma (group IV), renal tumors (group VI), and other malignant epithelial neoplasms and malignant melanomas (group XI). When the data were stratified by race, these associations were observed among whites, but not blacks. For leukemia (group I), poor counties had higher incidence rates than affluent counties for whites, but lower rates for blacks. This ecologic study provides perspective on area socioeconomic variations in childhood cancer incidence that warrants further research.

    Full Text Available Pneumonia is an important cause of morbidity and mortality among children throughout the world. Vaccines are available for some organisms, but they are underutilized and/or still in development. To evaluate the potential impact of vaccines, we review studies in which the etiology of childhood community-acquired pneumonia was recorded. In North America and Europe (9 studies, the etiology of pneumonia was established in 62% of studied children (range 43%-88% by use of noninvasive specific methods for microbiologic diagnosis. The most often identified agents were S. pneumoniae (22%, respiratory syncytial virus (RSV (20%, Haemophilus influenzae (7%, and Mycoplasma pneumoniae (15%. In Africa and South America (8 studies, bacteria were recovered from 56% (range 32%-68% of severely ill children studied by lung aspirate. The most often isolated bacteria were Streptococcus pneumoniae (33% and Haemophilus influenzae (21%. A high percentage of H. influenzae strains were not serotype b. Throughout the world, children requiring hospitalization were most likely to have infection caused by pneumococcus H. influenzae or RSV. Out patients also had Mycoplasma pneumoniae. Countries in Africa and Asia recorded 2 to 10 times more children with pneumonia (7 to 40/100 annually than in the USA. Widespread use of pneumococcal and H. influenzae type b conjugate vaccines could reduce the frequency of childhood pneumonia by one-third. Further reduction will require development of non-type b H. influenzae, RSV and M. pneumoniae vaccines. This could result in a > 50% reduction of pneumonia in children. This goal should be sought and achieved as soon as possible.

    Matthew S Kelly

    Full Text Available The highest incidence of childhood acute lower respiratory tract infection (ALRI is in low- and middle-income countries. Few studies examined whether detection of respiratory viruses predicts ALRI outcomes in these settings.We conducted prospective cohort and case-control studies of children 1-23 months of age in Botswana. Cases met clinical criteria for pneumonia and were recruited within six hours of presentation to a referral hospital. Controls were children without pneumonia matched to cases by primary care clinic and date of enrollment. Nasopharyngeal specimens were tested for respiratory viruses using polymerase chain reaction. We compared detection rates of specific viruses in matched case-control pairs. We examined the effect of respiratory syncytial virus (RSV and other respiratory viruses on pneumonia outcomes.Between April 2012 and August 2014, we enrolled 310 cases, of which 133 had matched controls. Median ages of cases and controls were 6.1 and 6.4 months, respectively. One or more viruses were detected from 75% of cases and 34% of controls. RSV and human metapneumovirus were more frequent among cases than controls, but only enterovirus/rhinovirus was detected from asymptomatic controls. Compared with non-RSV viruses, RSV was associated with an increased risk of treatment failure at 48 hours [risk ratio (RR: 1.85; 95% confidence interval (CI: 1.20, 2.84], more days of respiratory support [mean difference (MD: 1.26 days; 95% CI: 0.30, 2.22 days], and longer duration of hospitalization [MD: 1.35 days; 95% CI: 0.20, 2.50 days], but lower in-hospital mortality [RR: 0.09; 95% CI: 0.01, 0.80] in children with pneumonia.Respiratory viruses were detected from most children hospitalized with ALRI in Botswana, but only RSV and human metapneumovirus were more frequent than among children without ALRI. Detection of RSV from children with ALRI predicted a protracted illness course but lower mortality compared with non-RSV viruses.

    Background Pneumonia is common in children and mostly caused by many pathogens. The aim of this study was to investigate whether the incidence of pediatric mycoplasma pneumoniae (MP) pneumonia and respiratory syncytial virus (RSV) pneumonia was associated with meteorological factors in Hangzhou, China. Methods A total of 36500 pneumonia patients were recruited to participate in the study. Nasopharyngeal swabs were collected for the detection of MP and RSV using real-time polymerase chain reaction (RT-PCR) and direct immunofluorescence (DIF) assays, respectively. We used a distributed lag non-linear model (DLNM) to evaluate the correlations between the MP/RSV incidence and meteorological factors. Results The detection rates of MP and RSV were 18.4% and 10.4%, respectively. There was a positive correlation between temperature and the MP infection rate, but RSV infection rate was negatively associated with temperature. Moreover, the impact of temperature on infection with RSV presented evident lag and cumulative effects. There was also an evident lag effect of temperature on the infection rate of MP; however, there was no evident cumulative effect. Conclusions In this study, the results showed meteorological factors play an important role in the incidence of these two pathogens. All these results can provide the laboratory basis for the early diagnosis and treatment of pneumonia in children. PMID:28282391

    Full Text Available Introduction. Pneumonia is the most frequent nosocomial infection in intensive care units. The reported frequency varies with definition, the type of hospital or intensive care units and the population of patients. The incidence ranges from 6.8-27%. Objective. The objective of this study was to determine the frequency, risk factors and mortality of nosocomial pneumonia in intensive care patients. Methods. We analyzed retrospectively and prospectively the collected data of 180 patients with central nervous system infections who needed to stay in the intensive care unit for more than 48 hours. This study was conducted from 2003 to 2009 at the Clinical Centre of Kragujevac. Results. During the study period, 54 (30% patients developed nosocomial pneumonia. The time to develop pneumonia was 10±6 days. We found that the following risk factors for the development of nosocomial pneumonia were statistically significant: age, Glasgow Coma Scale (GCS score <9, mechanical ventilation, duration of mechanical ventilation, tracheostomy, presence of nasogastric tube and enteral feeding. The most commonly isolated pathogens were Klebsiella-Enterobacter spp. (33.3%, Pseudomonas aeruginosa (24.1%, Acinetobacter spp. (16.6% and Staphylococcus aureus (25.9%. Conclusion. Nosocomial pneumonia is the major cause of morbidity and mortality of patients with central nervous system infections. Patients on mechanical ventilation are particularly at a high risk. The mortality rate of patients with nosocomial pneumonia was 54.4% and it was five times higher than in patients without pneumonia.

    Full Text Available Introduction. The incidence rate of childhood type1 diabetes continues to rise across Europe by an average of approximately 3-4% per annum. Objective. The aim of this study was to examine incidence and trends of type 1 diabetes in children aged 0-14 years in Montenegro from 1997 to 2011. Methods. This was a prospective study. Primary case ascertainment was from a diabetes register, and a secondary independent data source was from hospital notifications. Case ascertainment was 100% complete using the capture-recapture method. Standardized incidence rates were calculated and trends estimated using the Poisson regression. Results. A total of 298 children (157 boys and 141 girls were diagnosed with type 1 diabetes before 15 years of age during 1997-2011. The mean age-standardized incidence was 15.0/100,000 persons (95% CI: 12.3-17.6 during this period, increasing from 11.7/100,000 in 1997 to 18.8/100,000 in 2011. The agespecific rates per 100,000 persons per year were 10.7, 17.2, and 18.2 at ages 0-4 years, 5-9 years, and 10-14 years, respectively. A significant linear trend in incidence (p = 0.002 has been observed over time, with an average annual increase of 4.2%. The increase in incidence was present in both genders, with the largest relative increase in the 0-4 years age group for boys (11.0%; p = 0.006. Conclusion. The incidence of type 1 diabetes in Montenegro children continues to increase. We need further monitoring and additional research in order to explain the cause.

    Full Text Available WAcute lower respiratory infections, which broadly include pneumonia and bronchiolitis, are still the leading cause of childhood mortality. ALRI contributed to 18% of all deaths in children younger than five years of age in 2008, and the main pathogens responsible for high mortality were Streptococcus pneumoniae, Haemophilus influenzae and respiratory syncytial virus. In addition, meningitis was estimated to contribute up to 200 000 deaths each year, and influenza anywhere between 25 000 and 110 000. It is widely acknowledged that a major portion of this mortality should be avoidable if universal coverage of all known effective interventions could be achieved. However, some evaluations of the implementation of World Health Organization’s (WHO Integrated Management of Childhood Illness (IMCI strategy, which promotes improved access to a trained health provider who can administer “standard case management”, have shown somewhat disappointing results. Only a minority of all children with life-threatening episodes of pneumonia, meningitis and influenza in developing countries have access to trained health providers and receive appropriate treatment. Thus, novel strategies for control of pneumonia that balance investments in scaling up of existing interventions and the development of novel approaches, technologies and ideas are clearly needed.

    Carbapenemase-producing Enterobacteriaceae are increasingly reported worldwide. The aim of the study was to determine the incidence and molecular epidemiology of carbapenemase-producing (CP) Escherichia coli and Klebsiella pneumoniae (CP-E/K) in Belgium. Eleven hospital-based laboratories collected carbapenem non-susceptible (CNS) isolates of E. coli and K. pneumoniae detected in clinical specimens from January 2013 to December 2014. All CNS strains were tested for carbapenemase production and typed by multilocus sequence typing (MLST) for a 6-month period as part of the European Survey on Carbapenemase-Producing Enterobacteriaceae in Europe (EuSCAPE) structured survey. In addition, an equal number of carbapenem-susceptible isolates collected were preserved as a control group for risk factor analysis. The overall incidence rate of CP-E/K isolates in hospitals increased from 0.124 in 2013 to 0.223 per 1000 admissions in 2014. From November 2013 to April 2014, 30 CP K. pneumoniae [OXA-48 (n = 16), KPC (n = 13), OXA-427 (n = 1)] and five CP E. coli [OXA-48 (n = 3), NDM (n = 1), OXA-427 (n = 1)] isolates were detected in ten hospitals. The 16 OXA-48-producing K. pneumoniae strains were distributed into eight sequence types (STs), while the 13 KPC-producing K. pneumoniae clustered into three STs dominated by ST512 (n = 7) and ST101 (n = 5). Compared to controls, we observed among CP-E/K carriers significantly higher proportion of males, respiratory origins, previous hospitalization, nosocomial setting, and a significantly lower proportion of bloodstream infections. Our study confirms the rapid spread of CP-E/K in Belgian hospitals and the urgent need for a well-structured and coordinated national surveillance plan in order to limit their dissemination.

    Full Text Available The Cooking and Pneumonia Study (CAPS is a pragmatic cluster-level randomized controlled trial of the effect of an advanced cookstove intervention on pneumonia in children under the age of 5 years (under 5s in Malawi (www.capstudy.org. The primary outcome of the trial is the incidence of pneumonia during a two-year follow-up period, as diagnosed by healthcare providers who are using the World Health Organization (WHO integrated management of childhood illnesses (IMCI pneumonia assessment protocol and who are blinded to the trial arms. We evaluated the quality of pneumonia assessment in under 5s in this setting via a cross-sectional study of provider-patient encounters at nine outpatient clinics located within the catchment area of 150 village-level clusters enrolled in the trial across the two study locations of Chikhwawa and Karonga, Malawi, between May and June 2015 using the IMCI guidelines as a benchmark. Data were collected using a key equipment checklist, an IMCI pneumonia knowledge test, and a clinical evaluation checklist. The median number of key equipment items available was 6 (range 4 to 7 out of a possible 7. The median score on the IMCI pneumonia knowledge test among 23 clinicians was 75% (range 60% to 89%. Among a total of 176 consultations performed by 15 clinicians, a median of 9 (range 3 to 13 out of 13 clinical evaluation tasks were performed. Overall, the clinicians were adequately equipped for the assessment of sick children, had good knowledge of the IMCI guidelines, and conducted largely thorough clinical evaluations. We recommend the simple pragmatic approach to quality assurance described herein for similar studies conducted in challenging research settings.

  2. Incident pneumonia and mortality in patients with chronic obstructive pulmonary disease. A double effect of inhaled corticosteroids?

    Festic, Emir; Scanlon, Paul D

    2015-01-15

    Inhaled corticosteroids are commonly prescribed for patients with severe chronic obstructive pulmonary disease. Although their use improves quality of life and reduces exacerbations, it is associated with increased risk of pneumonia. Curiously, their use has not been associated with increased risk of pneumonia-related or overall mortality. We review pertinent literature to further explore the effects of inhaled corticosteroids on incident pneumonia and mortality in patients with chronic obstructive pulmonary disease. The association of use of inhaled corticosteroids and incident pneumonia is substantial and has been present in the majority of the studies on the topic. This includes both randomized controlled trials and observational studies. However, all of the studies have substantial risk of bias. Most randomized trials are limited by lack of systematic ascertainment of pneumonia; they depended on adverse event reporting. Many observational studies included proper radiographic assessment of pneumonia, but they are limited by their retrospective, observational design. The unadjusted higher risk of pneumonia is associated with longer duration of use, more potent ICS compounds, and higher doses. That implies a dose-effect relationship. Unlike pneumonia, mortality is a precise outcome. Despite the robust association of inhaled corticosteroid use with increased risk of pneumonia, all studies find either no difference or a reduction in pulmonary-related and overall mortality associated with the use of inhaled corticosteroids. These observations suggest a double effect of inhaled corticosteroids (i.e., an adverse effect plus an unexplained mitigating effect).

    The role of stress ulcer prophylaxis in increasing the risk of pneumonia in ventilator patients was analyzed prospectively in 142 artificially ventilated patients at a medical and surgical intensive care unit (104 males, 38 females, mean time of ventilation 7.9 days, mean age 46.5 years). The pH of gastric aspirate and bacterial counts in gastric fluid and tracheal secretions were investigated daily. Identical isolates from gastric aspirates and tracheal secretions were typed by agglutination, bacteriocin, or phage typing. An average of 2.1 bacterial species were isolated in 80.5% of all gastric aspirates. Bacterial counts increased with rising gastric aspirate pH, which was especially true for Gram-negative and less so for Gram-positive organisms; colony counts of Candida sp. decreased slightly. In 31.6% of patients identical bacterial species were first isolated from gastric aspirates and 1 to 2 days later from tracheal secretions. Of these microbes that were first isolated from gastric aspirate and later from tracheal secretions, 50.3% were Gram-negative, 37.5% Gram-positive, and only 4.2% Candida sp. One-half of all bacterial aspirations occurred between the 2nd and 7th day of ventilation; 80% occurred within 11 days of ventilation. Only 20% of all migrations of Gram-positive organisms from stomach to respiratory tract lead to pneumonia, as compared with 60% of Gram-negatives. At a gastric pH below 3.4 the incidence of ventilation pneumonia was 40.6%; above pH 5.0 the incidence was 69.2% (P less than or equal to 0.05). As pH increased, the organism causing pneumonia was significantly more often isolated first from the gastric aspirate and 1 to 2 days later from the tracheal secretion of the same patient.

    Full Text Available Abstract Background This study aimed to determine the out-of pocket expenditure and coping strategies adopted by families of children admitted in a hospital in Bangladesh with pneumonia. Methods Trained interviewers surveyed parents of 90 children and conducted in-depth interviews with six families below the age of 5 years who were admitted to the largest pediatric hospital in Bangladesh with a diagnosis of pneumonia. We estimated the total cost of illness associated with hospitalization and explored the coping strategies of the families. Results The mean expenditure of the families for the illness episode was US$ 94 (±SD 52.5 with 75% having spent more than half of their total monthly expenditure on this hospitalization. Three fourths (68/90, 76% of the families managed the expenditure by borrowing, mortgaging or selling assets; 64% had to borrow the full cost of hospitalization and 10% borrowed from the formal sector with a monthly interest rate of 5 to 30%. The burden was highest for the people from poor income strata. Families earning ≤US$ 59 per month were 10 times more likely than families earning ≥US$ 59 per month to borrow money (OR = 10.0, 95% CI: 2.8-38.8. To repay their debts, 22% of families reported that they would work extra hours and 50% planned to reduce spending on food and education for their children. Conclusions Coping strategies adopted by the families to manage the out-of-pocket expenditure for children requiring hospitalization were catastrophic for the majority of the families. Efforts to prevent childhood pneumonia for example, by vaccination against the most common pathogens, by improving air quality and by improving childhood nutrition can provide a double advantage. They can prevent both disease and poverty.

    Full Text Available Background: Ventilator associated pneumonia (VAP are one of the most common nosocomial infections in intensive care unit (ICU. The ICU patients are at risk of stress ulcer and gastrointestinal bleeding for different reasons. In order to prevent this complication, anti acids are used for patients. This study compared pantoprazole with sucralfate in incidence of ventilator associated pneumonia. Materials and Methods: This randomized clinical trial was carried out on ICU patients with mechanical ventilation in Alzahra university hospital in Isfahan from 2010 to 2011. One hundred forty eight ventilated patients were randomly allocated in two groups. The first group was treated with sucralfate and the second group was treated with pantoprazole for stress ulcer prophylaxis and followed up during hospitalization in ICU for nosocomial pneumonia. Data analyzed by SPSS software. Results: One hundred thirty seven patients were selected for study. During the study period, 34 cases (24.8% acquired pneumonia, of which 10 were in the sucralfate group and 24 were in the pantoprazole group (14.1% vs. 36.4%. According to Chi-square test, rate of pneumonia was significantly lower in patients receiving sucralfate than the pantoprazole group ( P < 0.001. Conclusion: On the basis of the results, there is a significant relationship between the kind of drug used for stress ulcer and ventilator associated pneumonia. According to this article, rate of pneumonia was significantly lower in patients receiving sucralfate than the pantoprazole group.

    Mortality for childhood cancer has declined in Osaka, as well as all over Japan, since the 1970s, but whether this decline can be explained by trends of incidence or survival of childhood cancer has not been examined. A total of 5960 malignant tumors diagnosed between 1973 and 2001 in children Japan. The time trends for childhood cancer were analyzed over 29 years for incidence and 20 years for survival. Leukemia was the most common among childhood cancer for both sexes and accounted for one-third of all cases. The age-standardized annual incidence rate of all tumors was highest in 1988-1992: 155.1 per million for males and 135.9 for females. Five-year survival for all tumors improved from 50.1% in 1978-1982 to 73.0% in 1993-1997 for males and from 52.3% to 76.3% for females. Thus, the constant decline in mortality in childhood cancer was primarily due to improved survival between the 1970s and 1980s and reduced incidence after the 1990s.

    INTRODUCTION: Prophylactic antibiotics (PRO) reduce the incidence of early-onset pneumonia in comatose patients with structural brain injury, but have not been examined in cardiac arrest survivors undergoing targeted temperature management (TTM). We investigated the effect of PRO on the development...... of pneumonia in that population. METHODS: We conducted a retrospective cohort study comparing patients treated with PRO to those not receiving PRO (no-PRO) using Northern Hypothermia Network registry data. Cardiac arrest survivors ≥ 18 years of age with a GCS...-34 °C were enrolled in the registry. Differences were analyzed in univariate analyses and with logistic regression models to evaluate independent associations of clinical factors with incidence of pneumonia and good functional outcome. RESULTS: 416 of 1240 patients (33.5%) received PRO. Groups were...

    Analysis of cancer incidence, mortality, and survival rates can yield geographic and temporal trends that are useful for planning and evaluating health interventions. This article reviews cancer incidence and mortality rates and respective trends around the world in children under 15 years old, as well as their 5-year survival rates in developed and developing countries. We conclude that even though increasing or stable childhood cancer incidence rates and decreasing mortality rates have been observed in developed countries, the trends remain unknown in developing countries. Data from the city of Goiania, Brazil, show stable childhood cancer incidence and mortality rates. Five-year survival rates (48%) in Goiania are similar to those seen in underdeveloped regions and lower than those reported in developed countries (64-70%).

    Full Text Available Abstract Background United Nations High Commissioner for Refugees (UNHCR refugee camps are located predominantly in rural areas of Africa and Asia in protracted or post-emergency contexts. Recognizing the importance of malaria, pneumonia and diarrheal diseases as major causes of child morbidity and mortality in refugee camps, we analyzed data from the UNHCR Health Information System (HIS to estimate incidence and risk factors for these diseases in refugee children younger than five years of age. Methods Data from 90 UNHCR camps in 16 countries, including morbidity, mortality, health services and refugee health status, were obtained from the UNHCR HIS for the period January 2006 to February 2010. Monthly camp-level data were aggregated to yearly estimates for analysis and stratified by location in Africa (including Yemen or Asia. Poisson regression models with random effects were constructed to identify factors associated with malaria, pneumonia and diarrheal diseases. Spatial patterns in the incidence of malaria, pneumonia and diarrheal diseases were mapped to identify regional heterogeneities. Results Malaria and pneumonia were the two most common causes of mortality, with confirmed malaria and pneumonia each accounting for 20% of child deaths. Suspected and confirmed malaria accounted for 23% of child morbidity and pneumonia accounted for 17% of child morbidity. Diarrheal diseases were the cause of 7% of deaths and 10% of morbidity in children under five. Mean under-five incidence rates across all refugee camps by region were: malaria [Africa 84.7 cases/1000 U5 population/month (95% CI 67.5-102.0, Asia 2.2/1000/month (95% CI 1.4-3.0]; pneumonia [Africa 59.2/1000/month (95% CI 49.8-68.7, Asia 254.5/1000/month (95% CI 207.1-301.8]; and diarrheal disease [Africa 35.5/1000/month (95% CI 28.7-42.4, Asia 69.2/1000/month (95% CI 61.0-77.5].

    Background: Ventilator-associated pneumonia (VAP) is the most frequent Intensive Care Unit acquired infection. Aims: The aim is to determine the incidence, bacteriology and factors affecting VAP and to determine the multi-drug resistant (MDR) pathogens. Settings and Design: This was a prospective observational study conducted over a period of 1 year from April 1, 2011, to March 31, 2012. Materials and Methods: The patients fulfilling criteria of VAP were included in this study. Statistical Analysis: This was performed using SPSS trial version 11.0 software (SPSS Inc., Chicago, Illinois, USA) and the values of P < 0.05 were considered statistically significant. Results: Totally 74 (27.71%) patients were developed VAP. Of total 74 patients with VAP 53 (71.62%) were females and 21 (28.37%) were females (P < 0.0001). Total 13 (17.56%) patients had early-onset VAP and 61 (82.43%) had late-onset VAP (P < 0.0001). The overall incidence of VAP rate per 1000 ventilator days was 39.59. Total 126 bacterial isolates found in 74 patients with VAP. Predominant isolates were Gram-negative 52 (70.27%). Total 41 (55.40%) patients had polymicrobial VAP, and 33 (44.59%) had single isolate. Total 55 (43.65%) isolates were MDR organisms. Total 22 patients with VAP succumbed during treatment with overall case fatality rate of 29.72%. Of total 55 MDR isolates in VAP, 13 (26.63%) were Klebsiella spp., 11(20%) Pseudomonas aeruginosa, 14 (25.45%) Acinetobacter, 8 (14.54%) Escherichia coli, and 9 (16.36%) coagulase positive Staphylococcus aureus. Total 12 (21.41%) patients succumbed among MDR isolates. Conclusions: There was a high incidence of MDR pathogens in late-onset VAP. The Gram-negative organisms Klebsiella, Pseudomonas E. coli and Acinetobacter were the most commonly isolated organisms with high mortality rates.

  19. Temporal trends in childhood leukaemia incidence following exposure to radioactive fallout from atmospheric nuclear weapons testing.

    Notably raised rates of childhood leukaemia incidence have been found near some nuclear installations, in particular Sellafield and Dounreay in the United Kingdom, but risk assessments have concluded that the radiation doses estimated to have been received by children or in utero as a result of operations at these installations are much too small to account for the reported increases in incidence. This has led to speculation that the risk of childhood leukaemia arising from internal exposure to radiation following the intake of radioactive material released from nuclear facilities has been substantially underestimated. The radionuclides discharged from many nuclear installations are similar to those released into the global environment by atmospheric nuclear weapons testing, which was at its height in the late-1950s and early-1960s. Measurements of anthropogenic radionuclides in members of the general public resident in the vicinity of Sellafield and Dounreay have found levels that do not differ greatly from those in persons living remote from nuclear installations that are due to ubiquitous exposure to the radioactive debris of nuclear weapons testing. Therefore, if the leukaemia risk to children resulting from deposition within the body of radioactive material discharged from nuclear facilities has been grossly underestimated, then a pronounced excess of childhood leukaemia would have been expected as a consequence of the short period of intense atmospheric weapons testing. We have examined childhood leukaemia incidence in 11 large-scale cancer registries in three continents for which data were available at least as early as 1962. We found no evidence of a wave of excess cases corresponding to the peak of radioactive fallout from atmospheric weapons testing. The absence of a discernible increase in the incidence of childhood leukaemia following the period of maximum exposure to the radioactive debris of this testing weighs heavily against the suggestion that

    Reported are the results of a case-control study carried out between July 1989 and June 1990 in Fortaleza city, Ceará State, Brazil, to determine the factors that place young children living in urban slum conditions at increased risk of contracting pneumonia. Cases were 650 under-2-year-olds with a radiological diagnosis of pneumonia who were recruited at the main paediatric hospital in the city over a full calendar year. Age-matched controls were recruited from the neighbourhood where the cases lived. Cases and controls were compared with respect to a variety of sociodemographic, environmental, reproductive, nutritional, and morbidity factors, and a risk factor questionnaire was administered to the mother of each child or to the child's normal guardian. Cases and controls were also weighed and measured. Malnutrition was the most important risk factor for childhood pneumonia in the study population, with weight-for-age, height-for-age, and weight-for-height also being important risk factors. In view of the high prevalence of stunting in the study population, there is an urgent need to reduce the level of malnutrition as a priority. Attendance at a day care centre was also associated with a high odds ratio. In view of the growing numbers of children attending day care centres in both developing and developed countries, it is essential that ways be identified to improve the design and management of such centres in order to minimize the risk of pneumonia. Increased risks of childhood pneumonia were also associated with low birth weight, non-breast-feeding, crowding, high parity, and incomplete vaccination status, but not with socioeconomic status or environmental variables. Finally, children who had suffered from previous episodes of wheezing or been hospitalized for pneumonia had a greater than threefold increased risk of contracting the disease.

    Most studies on the frequency of autism have had methodological problems. Most notable of these have been differences in diagnostic criteria between studies, degree of cases overlooked by the initial screening, and type of measurement. This study aimed to replicate the first report on childhood autism to address cumulative incidence as well as prevalence, as defined in the International Statistical Classification of Diseases and Related Health Problems, 10th revision (ICD-10) Diagnostic Criteria for Research. Here, the same methodological accuracy (exactness of a measurement to the true value) as the first study was used, but population size was four times larger to achieve greater precision (reduction of random error). A community-oriented system of early detection and early intervention for developmental disorders was established in the northern part of Yokohama, Japan. The city's routine health checkup for 18-month-old children served as the initial mass screening, and all facilities that provided child care services aimed to detect all cases of childhood autism and refer them to the Yokohama Rehabilitation Center. Cumulative incidence up to age 5 years was calculated for childhood autism among a birth cohort from four successive years (1988 to 1991). Cumulative incidence of childhood autism was 27.2 per 10000. Cumulative incidences by sex were 38.4 per 10000 in males, and 15.5 per 10000 in females. The male:female ratio was 2.5:1. The proportions of children with high-functioning autism who had Binet IQs of 70 and over and those with Binet IQs of 85 and over were 25.3% and 13.7% respectively. Data on cumulative incidence of childhood autism derived from this study are the first to be drawn from an accurate, as well as precise, screening methodology.

    Prior to 2005, 51% of children in Mexico diagnosed with cancer received no standardized optimal multidisciplinary medical care. A government-subsidized national cancer treatment program was therefore created for these patients and a National Cooperative Childhood Cancer Treatment Group was consequently formed for these patients. Pediatric patients with a proven diagnosis of leukemia, lymphoma or solid tumor and who were registered in the Popular Medical Insurance (PMI) program from January 2007 to December 2010, are described in this report. These patients had been enrolled and registered in one of the 49 nationwide certified medical institutions in Mexico. The national incidence and frequency data for childhood cancers were analyzed for the whole program. At the end of a 4-year study, the analysis revealed that 8,936 children from across Mexico had been diagnosed with cancer. The incidence rate for the PMI patients was 150.3/million/year (2010) for children of 0-18 years. The highest age incidence rate was 51.9 between 0 and 4 years and boys were the predominant group for all types of cancer. The leukemia incidence was 75.3/million/year (2010), and an average frequency of 50.75% throughout the 4 years. The overall mortality rate was measured at 5.4/100,000/year (2010). This study demonstrates a high frequency and incidence of childhood cancer and a beneficial impact of the PMI program over the quality of life in these children.

    Objectives To compare the proportion of Beijing children who have ever had pneumonia (%Pneumonia) to those in other locations, and to estimate by how much national vaccine coverage with Pneumococcal Conjugate Vaccine (PCV) and Haemophilus Influenzae Type b (Hib) could reduce Beijing %Pneumonia. Methods %Pneumonia was obtained for each age group from 1 to 8 years inclusive from 5,876 responses to a cross-sectional questionnaire. Literature searches were conducted for world-wide reports of %Pneumonia. Previous vaccine trials conducted worldwide were used to estimate the pneumococcal (S. pneumoniae) and Hib (H. influenzae) burdens and %Pneumonia as well as the potential for PCV and Hib vaccines to reduce Beijing children’s %Pneumonia. Findings The majority of pneumonia cases occurred by the age of three. The cumulative %Pneumonia for 3–8 year-old Beijing children, 26.9%, was only slightly higher than the 25.4% for the discrete 3 year-old age group, similar to trends for Tianjin (China) and Texas (USA). Beijing’s %Pneumonia is disproportionally high relative to its Gross National Income (GNI) per capita, and markedly higher than %Pneumonia in the US and other high GNI per capita countries. Chinese diagnostic guidelines recommend chest X-ray confirmation while most other countries discourage it in favor of clinical diagnosis. Literature review shows that chest X-ray confirmation returns far fewer pneumonia diagnoses than clinical diagnosis. Accordingly, Beijing’s %Pneumonia is likely higher than indicated by raw numbers. Vaccine trials suggest that national PCV and Hib vaccination could reduce Beijing’s %Pneumonia from 26.9% to 19.7% and 24.9% respectively. Conclusion National PCV and Hib vaccination programs would substantially reduce Beijing children’s pneumonia incidence. PMID:28166256

    Background The pneumococcal conjugate vaccine’s (PCV) impact on childhood pneumonia during programmatic conditions in Africa is poorly understood. Following PCV13 introduction in Malawi in November 2011, we evaluated the case burden and rates of childhood pneumonia. Methods and Findings Between January 1, 2012-June 30, 2014 we conducted active pneumonia surveillance in children 75% three-dose PCV13 coverage (post). We also used multivariable time-series regression, adjusting for autocorrelation and exploring seasonal variation and alternative model specifications in sensitivity analyses. The early versus post analysis showed an increase in cases and rates of total, fast breathing, and indrawing pneumonia and a decrease in danger sign and hypoxemic pneumonia, and pneumonia mortality. At 76% three-dose PCV13 coverage, versus 0%, the time-series model showed a non-significant increase in total cases (+47%, 95% CI: -13%, +149%, p = 0.154); fast breathing cases increased 135% (+39%, +297%, p = 0.001), however, hypoxemia fell 47% (-5%, -70%, p = 0.031) and hospital deaths decreased 36% (-1%, -58%, p = 0.047) in children <5 years. We observed a shift towards disease without danger signs, as the proportion of cases with danger signs decreased by 65% (-46%, -77%, p<0.0001). These results were generally robust to plausible alternative model specifications. Conclusions Thirty months after PCV13 introduction in Malawi, the health system burden and rates of the severest forms of childhood pneumonia, including hypoxemia and death, have markedly decreased.

    Full Text Available Context and Aim: Ventilator-associated pneumonia (VAP remains to be the commonest cause of hospital morbidity and mortality in spite of advances in diagnostic techniques and management. This project aims to study the various risk factors and the common microbial flora associated with VAP. It also evaluates the use of APACHEIII scores for prognostication. Study Design: A prospective cohort study was conducted over 1 year in medical critical care unit (CCU of a tertiary-care teaching hospital. Methods and Material: VAP was diagnosed using the clinical pulmonary infection score (CPIS of more than 6. The study cohort comprised 51 patients. All CCU patients requiring mechanical ventilation for more than 48 h formed the study group. Statistical Analysis Used: Univariate analysis, c2-test, and paired "t-test." Results: Twenty-four out of fifty-one cases developed VAP. These cases had an average APACHEIII score of more than 55 on admission to critical care unit (CCU. They needed prolonged mechanical ventilation and had lower PaO2/FiO2 ratio as compared with the remaining patients who did not develop VAP. Pseudomonas aeroginosa was the commonest and most lethal organism. The mortality in the VAP group was 37% and correlated very well with higher APACHEIII scores on admission. Conclusions: Longer duration of mechanical ventilation and the need of reintubation are associated with proportionate rise in the incidence of VAP. Deteriorating PaO2/FiO2 ratio correlated well with the onset of VAP. Higher APACHEIII scores on admission stratify the mortality risk.

    Full Text Available Introduction: Ventilator-associated pneumonia is a common complication of mechanical ventilation. This study aimed to evaluate the effect of designed respiratory care program on incidence of ventilator-associated pneumonia (VAP in the mechanically ventilated patient. Methods: In this clinical trial, 64 patients were selected among those who had undergone mechanical ventilation in the ICU of Al‑Zahra Hospital, Isfahan, Iran, using convenience sampling method. The subjects were randomly allocated to intervention and control groups. In the intervention group an upper respiratory care program and in the control group, routine cares were done. Modified Clinical Pulmonary Infection Questionnaire was completed before and on the third, fourth and fifth day of study. Data were analyzed by Chi-square and independent t-test through SPSS Ver.13. Results: The results of this study showed that until the third day of study, the incidence of VAP was similar in the both groups. However, on the fifth day of study, the incidence of VAP in the intervention group was significantly lower than control group. Conclusion: The results of this study showed that an upper respiratory care program reduced the incidence of VAP. Therefore, nurses are recommended to perform this program for prevention of VAP.

    Inorganic arsenic exposure through drinking water causes cancer in adults; however, the carcinogenic potential in children remains unknown. A recent leukemia cluster in Churchill County, Nevada, where arsenic levels in water supplies are relatively high, has prompted concern. The authors investigated the incidence of childhood cancer between 1979 and 1999 in all 17 Nevada counties, grouped by low (i.e., water supplies. The standardized incidence ratios (SIRs) for all childhood cancers combined were 1.00 (95% confidence interval [CI] = 0.94, 1.06), 0.72 (95% CI = 0.43, 1.12), and 1.25 (95% CI = 0.91, 1.69) for low-, medium-, and high-exposure counties, respectively. There was no relationship between arsenic levels in water and childhood leukemia (SIRs = 1.02, 0.61, and 0.86, respectively [95% CIIs = 0.90, 1.15; 0.12, 1.79; and 0.37, 1.70, respectively]). For all childhood cancers, excluding leukemias, the SIRs were 0.99 (95% CI = 0.92, 1.07), 0.82 (95% CI = 0.42, 1.22), and 1.37 (0.92, 1.83), respectively. The excess in 5- to 9-yr-old children and 10- to 14-yr-old children was in bone cancers, and the excess in 15- to 19-yr-old young adults was primarily in lymphomas. The findings in this study are reassuring in that leukemia risks were not increased at the concentrations of arsenic in water found in this study. Nonetheless, the results raise the possibility that there are increased risks for nonleukemic childhood cancers that require confirmation in other studies, particularly those in which higher exposures are addressed.

    PURPOSE Nonspecific abdominal pain (NSAP) is a common complaint in childhood. In specialist care, childhood NSAP is considered to be a complex and time-consuming problem, and parents are hard to reassure. Little is known about NSAP in family practice, but the impression is that family physicians consider it to be a benign syndrome needing little more than reassurance. This discrepancy calls for a better understanding of NSAP in family practice. METHODS Data were obtained from the Second Dutch National Survey of General Practice (2001). Using registration data of 91 family practices, we identified children aged 4 to 17 years with NSAP. We calculated the incidence, and we studied factors associated with childhood NSAP, referrals, and prescriptions. RESULTS The incidence of NSAP was 25.0 (95% confidence interval [CI], 23.7–26.3) per 1,000 person years. Most children (92.7%) with newly diagnosed NSAP (N = 1,480) consulted their doctor for this condition once or twice. Factors independently associated with NSAP were female sex (odds ratio [OR] = 1.4; 95% CI, 1.3–1.5), nongastrointestinal-nonspecific somatic symptoms (OR = 1.3; 95% CI, 1.1–1.5), and health care use (OR = 1.04; 95% CI, 1.03–1.05). When NSAP was diagnosed at the first visit, 3% of the patients were referred to specialist care, and 1% received additional testing. Family physicians prescribed medication in 21.3% of the visits for NSAP. CONCLUSIONS Childhood NSAP is a common problem in family practice. Most patients visit their doctor once or twice for this problem. Family physicians use little additional testing and make few referrals in their management of childhood NSAP. Despite the lack of evidence for effectiveness, family physicians commonly prescribe medication for NSAP. PMID:21747105

    INTRODUCTION: Nosocomial pneumonia in relation to tracheotomy is a well-known complication. The aim of the present study was to study prophylactic antibiotics at the time of tracheotomy as a protective factor against nosocomial pneumonia. METHODS: A retrospective follow-up study was conducted...... for inclusion, forming a group without antibiotics (n = 53) treatment and a group with antibiotics (n = 35) treatment. RESULTS: In the group without antibiotics, 67% (n = 34) developed pneumonia (not including aspirational) versus 44% (n = 14) in the group with antibiotics (p = 0.04). The 30-day mortality...... was 10% (n = 9), and the one-year mortality was 58% (n = 42) for the total population, with no statistically significant differences between the groups. Pneumonia after tracheotomy prolonged the hospitalisation time regardless of grouping. In the group without antibiotics, the median was seven days...

    In 1992, the diabetes registry was started in Kuwait, as part of DiaMond, a WHO multinational collaborative project on the incidence of childhood-onset diabetes. Children (243) aged below 15 years, were identified between 1 January 1992 and 31 December 1995. Children (203) were Kuwaiti and 40 were non-Kuwaiti children but resident of Kuwait. For the years 1992, 1993, the annual incidence of childhood onset diabetes for Kuwaiti children was 15.4 per 100,000 (95% confidence interval 12.9-19), and the degree of ascertainment was 92%. Polyuria, polydypsia, weight loss and nocturia were the most frequently reported symptoms; four children were in coma and one in shock at presentation. Nearly half of the children (49%) presented ketoacidosis (venous pH < 7.3 and/or plasma bicarbonate level < 18 mmol/l). and in 53 children (23.5%) it was severe (venous pH < 7.1 and/or plasma bicarbonate level < 10 mmol/l). In 62 children (25.5%) it was mild to moderate (venous pH 7.1-7.3 and/or plasma bicarbonate level 10.1-18 mmol/l). The incidence of severe ketoacidosis was similar in all age groups and sexes. All children recovered completely without major complications and no deaths were recorded. We conclude that diabetic ketoacidosis is a common presentation at the onset of diabetes in childhood in Kuwait and attests to the lack of awareness of general practitioners and parents to the symptoms and signs of diabetes in childhood.

    Full Text Available Ventilator-Associated Pneumonia is the second most common nosocomial infection and the first most common infection in Intensive Care Units .The present study was conducted to investigate the Epidemiology of ventilatorassociated pneumonia in intensive care units of hospitals affiliated to Mazandaran University of Medical Sciences. The present descriptive-analytical study was conducted in ICU patients in hospitals in Mazandaran province over a period of 14 months. The research setting consisted of the ICUs of hospitals in Mazandaran province in Iran. The study population consisted of patients over the age of 18 hospitalized in these units and connection to mechanical ventilation. The patients’ data were collected on a daily basis by the hospital infection control staff. The statistical analysis of the data was carried out in SPSS version 20 Results: Of the total of 562 patients examined (5965 days, 205 developed VAP (36.5%.The incidence of VAP was reported as 34.367% per each 1000 days of tracheal intubation. The incidence of VAP was directly correlated with reintubation, age, the duration of ventilation, the Glasgow coma score, nasogastric intubation, the use of stress ulcer prophylaxis, the use of mouthwash and tracheostomy. Conclusion: The incidence of VAP was almost twice the global rate in this study. Gram-negative bacteria were the most common cause of VAP and multi-antibiotic resistance was also perceived among the participants. This problem can be solved if changes are made to the empirical treatment of patients based on the careful assessment of multiantibiotic resistant organisms

    The objective of this study was to examine childhood cancer incidence in proximity to nuclear power plants in Illinois. Cancer cases diagnosed among Illinois children 0 to 14 years old from 1986 through 2005 were included in the study. Standardized incidence ratio (SIR) was calculated for the geographic zones defined by the proximity to nuclear power plants. The results show that children living within 10 miles of any nuclear power plant did not have significant increase in incidence for leukemia (period 1986-1995: SIR = 0.85 [95% confidence interval, CI: 0.54-1.26]; period 1996-2005: 1.23 [0.91-1.64]), lymphomas [period 1986-1995: 1.38 [0.77-2.27]; period 1996-2005: 0.77 [0.37-1.42]), or other cancer sites. Neither did the children living 10 to 20 miles or 20 to 30 miles from any nuclear power plants. This study did not find any significant childhood cancer excess among children living near nuclear plants and did not observe any dose-response patterns.

    Full Text Available Background. Efforts to reduce child mortality especially in Africa must as a necessity aim to decrease mortality due to pneumonia. To achieve this, preventive strategies such as expanding vaccination coverage are key. However once a child develops pneumonia prompt treatment which is essential to survival is dependent on mothers and caregiver recognition of the symptoms and danger signs of pneumonia. Methods. This community based cross-sectional study enrolled four hundred and sixty-six caregivers in Enugu state. It aimed to determine knowledge of caregivers about danger signs of pneumonia and the sociodemographic factors that influence knowledge and care seeking behaviour of caregivers. Results. There is poor knowledge of the aetiology and danger signs of pneumonia among caregivers. Higher maternal educational attainment and residence in semiurban area were significantly associated with knowledge of aetiology, danger signs, and vaccination of their children against pneumonia. Fast breathing and difficulty in breathing were the commonest known and experienced WHO recognized danger signs while fever was the commonest perceived danger sign among caregivers. Conclusion. Knowledge of danger signs and health seeking behaviour among caregivers is inadequate. There is need for intensified public and hospital based interventions targeted at mothers to improve their knowledge about pneumonia.

    To determine whether there was any difference in childhood leukemia incidence rates between populations living in the proximity to oil fields and those living in areas free from oil exploitation in the Amazon basin of Ecuador, 91 cancer cases among children (0-14 years) from the provinces of Sucumbios, Orellana, Napo, and Pastaza during the period 1985-2000 were studied. The relative risks for all leukemias indicated significantly elevated levels in the youngest age group (0-4 years), both genders combined (RR 3.48, 95% CI 1.25-9.67), and in all age groups (0-14 years) combined for females (RR 2.60, 95% CI 1.11-6.08) and both genders combined (RR 2.56, 95% CI 1.35-4.86). There was no significant difference between the two groups in all other cancer sites combined. Study results are compatible with a relationship between childhood leukemia incidence and living in the proximity of oil fields in the Ecuadorian Amazon.

    Full Text Available Background: Ventilator-associated pneumonia (VAP is the most common nosocomial infection diagnosed in the intensive care unit (ICU and in spite of advances in diagnostic techniques and management it remains a common cause of hospital morbidity and mortality. Objective: The primary objective of the following study is to determine the incidence, various risk factors and attributable mortality associated with VAP and secondary objective is to identify the various bacterial pathogens causing VAP in the ICU. Materials and Methods: This prospective observational study was carried out over a period of 1 year. VAP was diagnosed using the clinical pulmonary infection score. Endotracheal aspirate (ETA and bronchoalveolar lavage (BAL samples of suspected cases of VAP were collected from ICU patients and processed as per standard protocols. Statistical Analysis: Fisher′s exact test was applied when to compare two or more set of variables were compared. Results: The incidence of VAP in our study was 57.14% and the incidence density of VAP was 31.7/1000 ventilator days. Trauma was the commonest underlying condition associated with VAP. The incidence of VAP increased as the duration of mechanical ventilation increased and there was a total agreement in bacteriology between semi-quantitative ETAs and BALs in our study. The overall mortality associated with VAP was observed to be 48.33%. Conclusions: The incidence of VAP was 57.14%. Study showed that the incidence of VAP is directly proportional to the duration of mechanical ventilation. The most common pathogens causing VAP were Acinetobacter spp. and Pseudomonas aeruginosa and were associated with a high fatality rate.

    Full Text Available BACKGROUND AND OBJECTIVES: Nosocomial pneumonia (NP is defined as parenchymal lung infection, occurring after the first 48 hours of hospital admission. Ventilator Associated Pneumonia (VAP is the most common cause of nosocomial pneumonia. The clinical presentation and organisms causing the VAP are different in different set ups. Hence early diagnosis and management of these patients will decrease morbidity and also the mortality. AIM OF STUDY: Is to find the most common organism, sensitivity, and clinical profile of the patients suffering from VAP. MATERIALS AND METHODS: All patients on mechanical ventilation admitted in Intensive Care Units (ICU of Basaweshwar Teaching and General Hospital attached to M.R.M.C Gulbarga for approximately 2 years from September 2010 to June 2012 were considered. Patients under study were those satisfying inclusion criteria and a detail history and clinical examination of the selected patients was taken. RESULTS: 224 patients were put on mechanical ventilator during the study period of them 60 patients developed VAP. Out of 60patients, 29 developed early onset and 31 developed late onset VAP. The most common sign in early onset VAP was crepitation (83% and late onset were fever and tachycardia (61%. Commonest organism isolated in early onset VAP was Pseudomonas and Staphylococcus aureus (21% and Pseudomonas (52% in late onset. Piperacillin, meropenem and vancomycin were the most common antibiotics for which cultures were sensitive in early onset VAP, as compared to meropenem, vancomycin and levofloxacin in late onset VAP. Commonest risk factors in early and late onset VAP was use of H2 blockers (97% and 100% respectively. late onset VAP had very high mortality rate of 71% as compared to only 17% in early onset VAP. CONCLUSION: Keen observation, clinical, radiological examination and culture sensitivity of respiratory secretions of ventilated patients in ICU would help to detect early onset of VAP. This early

    Full Text Available Abstract Background Pneumonia is a leading cause of children's deaths in developing countries and hinders achievement of the fourth Millennium Development Goal. This goal aims to reduce the under-five mortality rate, by two thirds, between 1990 and 2015. Few studies have examined the impact of zinc adjunct therapy on the outcome of childhood pneumonia. We determined the effect of zinc as adjunct therapy on time to normalization of respiratory rate, temperature and oxygen saturation. We also studied the effect of zinc adjunct therapy on case fatality of severe childhood pneumonia (as a secondary outcome in Mulago Hospital, Uganda. Methods In this double blind, randomized, placebo-controlled clinical trial, 352 children aged 6 to 59 months, with severe pneumonia were randomized to zinc (20 mg for children ≥12 months, and 10 mg for those Results Time to normalization of the respiratory rate, temperature and oxygen saturation was not significantly different between the two arms. Case fatality was 7/176 (4.0% in the zinc group and 21/176 (11.9% in the placebo group: Relative Risk 0.33 (95% CI 0.15 to 0.76. Relative Risk Reduction was 0.67 (95% CI 0.24 to 0.85, while the number needed to treat was 13. Among HIV infected children, case fatality was higher in the placebo (7/27 than in the zinc (0/28 group; RR 0.1 (95% CI 0.0, 1.0.

    The annual incidence of leukaemia among children aged up to 14 years as estimated by the Manchester Children's Tumour Registry has been analysed for the 24 years 1954-1977. A significant increase in acute lymphoid leukaemia (ALL) was found, while the incidence of acute myeloid leukaemia (AML) remained constant. Other types of leukaemia were too rare to be analysed separately. The increase in ALL was concentrated among boys in the 1--5-year age group. Analysis with respect to initial white-cell count showed the increase to be more pronounced in children with initial white cell counts of 1-5 x 10(4)/microliters. The proportion of cases presenting in Lancashire compared with Greater Manchester did not change during the study period. The distribution of cases with respect to social class and socio-economic group of the parents also remained constant. Due to advances in the treatment of childhood ALL survival improved considerably during the study period and no increase in mortality was seen.

    BACKGROUND Childhood leukemia incidence and survival varies globally, and this variation may be attributed to environmental risk factors, genetics, and/or disparities in diagnosis and treatment. PROCEDURE We analyzed childhood leukemia incidence and survival trends in children age 0–19 years from 1990 to 2011 in Songkhla, Thailand (n=316) and compared these results to US data from the Surveillance, Epidemiology, and End Results (SEER) registry (n=6,738). We computed relative survival using Ederer II and estimated survival functions using the Kaplan-Meier method. Changes in incidence and five-year survival by year of diagnosis were evaluated using joinpoint regression and are reported as annual percent changes (APC). RESULTS The age-standardized incidence of leukemia was 3.2 and 4.1 cases per 100,000 in Songkhla and SEER-9, respectively. In Songkhla, incidence from 1990–2011 significantly increased for leukemia (APC=1.7%, p=0.031) and acute lymphoblastic leukemia (ALL) (APC=1.8%, p=0.033). Acute myeloid leukemia (AML) incidence significantly increased (APC=4.2%, p=0.044) and was significantly different from the US (p=0.026), where incidence was stable during the same period (APC=0.3%, p=0.541). The overall five-year relative survival for leukemia was lower than that reported in the US (43% vs. 79%). Five-year survival significantly improved by at least 2% per year from 1990–2011 in Songkhla for leukemia, ALL, and AML (p<0.050). CONCLUSIONS While leukemia and ALL incidence increased in Songkhla, differences in leukemia trends, particularly AML incidence, may suggest etiologic or diagnostic differences between Songkhla and the US. This work highlights the importance of evaluating childhood cancer trends in low- and middle-income countries. PMID:25962869

    Against a background of point-source outbreaks of Pneumocystis pneumonia (PCP) in renal transplant units in Europe, we undertook a retrospective 3 year observational review of PCP in Northern Ireland. This showed an unexpected increase in incidence, with a mortality rate of 30 %. Fifty-one cases were confirmed compared to 10 cases confirmed in the preceding 7 years. Where undiagnosed HIV infection had previously been the main risk factor for PCP, this was now equally matched by chemotherapy for haematological and non-haematological malignancy and immune suppression for a range of autoimmune conditions. Congenital immunodeficiency and transplantation were less common predisposing factors, but renal grafts also showed a rising incidence. Asymptomatic carriage was uncommon. At presentation both upper and lower respiratory samples were of equal use in establishing the diagnosis, and treatment resulted in rapid clearance. These data suggest the need for considering PCP in at-risk patients, reviewing its mode of acquisition and whether iatrogenic colonization is a treatable pre-condition.

    Full Text Available Ventilator-associated pneumonia (VAP is a major cause of hospital morbidity and mortality despite recent advances in diagnosis and accuracy of management. However, as taught in medical science, prevention is better than cure is probably more appropriate as concerned to VAP because of the fact that it is a well preventable disease and a proper approach decreases the hospital stay, cost, morbidity and mortality. The aim of the study is to critically review the incidence and outcome, identify various risk factors and conclude specific measures that should be undertaken to prevent VAP. We studied 100 patients randomly, kept on ventilatory support for more than 48 h. After excluding those who developed pneumonia within 48 h, VAP was diagnosed when a score of ≥6 was obtained in the clinical pulmonary infection scoring system having six variables and a maximum score of 12. After evaluating, the data were subjected to univariate analysis using the chi-square test. The level of significance was set at P96 h was 73%. Late-onset VAP had poor prognosis in terms of mortality (66% as compared to the early-onset type (20%. The mortality of patients of the non-VAP group was found to be 41% while that of VAP patients was 54%. Targeted strategies aimed at preventing VAP should be implemented to improve patient outcome and reduce length of intensive care unit stay and costs. Above all, everyone of the critical care unit should understand the factors that place the patients at risk of VAP and utmost importance must be given to prevent VAP.

    David L Hudacek

    Full Text Available BACKGROUND: Pneumonia, diarrhea and measles are the leading causes of death in children worldwide, but have a disproportionately low share of international funding and media attention. In comparison, AIDS, tuberculosis and malaria--diseases that also significantly affect children--receive considerably more funding and have relatively high media coverage. This study investigates the potential relationship between media agenda setting and funding levels in the context of the actual burden of disease. METHODS: The news databases Lexis Nexis, Factiva, and Google News Archive were searched for the diseases AIDS, TB and Malaria and for lower funded pediatric diseases: childhood pneumonia, diarrhea, and measles. A sample of news articles across geographic regions was also analyzed using a qualitative narrative frame analysis of how the media stories were told. RESULTS: There were significantly more articles addressing the Global Fund diseases compared to the lower funded pediatric diseases between 1981 and 2008 (1,344,150 versus 291,865 articles. There were also notable differences in the framing of media narratives: 1 There was a high proportion of articles with the primary purpose of raising awareness for AIDS, TB and malaria (46.2% compared with only 17.9% of the pediatric disease articles. 2 Nearly two-thirds (61.5% of the AIDS, tuberculosis and malaria articles used a human rights, legal or social justice frame, compared with 46.2% for the lower funded pediatric disease articles, which primarily used an ethical or moral frame. CONCLUSION: This study demonstrates that lower funded pediatric diseases are presented differently in the media, both quantitatively and qualitatively, than higher funded, higher profile diseases.

    Beverly D Bradley

    Full Text Available BACKGROUND: Planning for the reliable and cost-effective supply of a health service commodity such as medical oxygen requires an understanding of the dynamic need or 'demand' for the commodity over time. In developing country health systems, however, collecting longitudinal clinical data for forecasting purposes is very difficult. Furthermore, approaches to estimating demand for supplies based on annual averages can underestimate demand some of the time by missing temporal variability. METHODS: A discrete event simulation model was developed to estimate variable demand for a health service commodity using the important example of medical oxygen for childhood pneumonia. The model is based on five key factors affecting oxygen demand: annual pneumonia admission rate, hypoxaemia prevalence, degree of seasonality, treatment duration, and oxygen flow rate. These parameters were varied over a wide range of values to generate simulation results for different settings. Total oxygen volume, peak patient load, and hours spent above average-based demand estimates were computed for both low and high seasons. FINDINGS: Oxygen demand estimates based on annual average values of demand factors can often severely underestimate actual demand. For scenarios with high hypoxaemia prevalence and degree of seasonality, demand can exceed average levels up to 68% of the time. Even for typical scenarios, demand may exceed three times the average level for several hours per day. Peak patient load is sensitive to hypoxaemia prevalence, whereas time spent at such peak loads is strongly influenced by degree of seasonality. CONCLUSION: A theoretical study is presented whereby a simulation approach to estimating oxygen demand is used to better capture temporal variability compared to standard average-based approaches. This approach provides better grounds for health service planning, including decision-making around technologies for oxygen delivery. Beyond oxygen, this approach

    According to World Health Organization, pneumonia is the respiratory disease with the highest pediatric mortality rate accounting for 15% of all deaths of children under 5 years old worldwide. The diagnosis of pneumonia is commonly made by clinical criteria with support from ancillary studies and also laboratory findings. Chest imaging is commonly done with chest X-rays and occasionally with a chest CT scan. Lung ultrasound is a promising alternative for chest imaging; however, interpretation is subjective and requires adequate training. In the present work, a two-class classification algorithm based on four Gray-level co-occurrence matrix texture features (i.e., Contrast, Correlation, Energy and Homogeneity) extracted from lung ultrasound images from children aged between six months and five years is presented. Ultrasound data was collected using a L14-5/38 linear transducer. The data consisted of 22 positive- and 68 negative-diagnosed B-mode cine-loops selected by a medical expert and captured in the facilities of the Instituto Nacional de Salud del Niño (Lima, Peru), for a total number of 90 videos obtained from twelve children diagnosed with pneumonia. The classification capacity of each feature was explored independently and the optimal threshold was selected by a receiver operator characteristic (ROC) curve analysis. In addition, a principal component analysis was performed to evaluate the combined performance of all the features. Contrast and correlation resulted the two more significant features. The classification performance of these two features by principal components was evaluated. The results revealed 82% sensitivity, 76% specificity, 78% accuracy and 0.85 area under the ROC.

    Full Text Available Background: Ventilator associated pneumonia (VAP, a hospital acquired infection (HAI is seen among critically ill patients on mechanical ventilation (MV due to various causes, in intensive care units (ICUs. VAP increases morbidity, mortality, as well as the cost of healthcare. Materials and Methods: A prospective study was done over a period of 10 months in a tertiary care hospital in India to determine the incidence, etiological agents, their sensitivity profiles, and risk factors associated with VAP. Combination disc method, ethylenediaminetetraacetic acid (EDTA disc synergy (EDS tests, and AmpC disc tests were performed for detection of extended-spectrum beta-lactamases (ESBL, metallo-beta-lactamases (MBL, and AmpC beta-lactamases, respectively. Results: One hundred and forty adult patients, on MV for 48 h and more, were included and 28 (20% developed VAP. The incidence density rate of VAP was 21.875 per 1,000 ventilator days. Most of the patients had late onset VAP (60.7% with average number of days for onset around 8 days. Pseudomonas spp. and Acinetobacter spp. were significantly associated with late onset VAP, whereas Enterobacteriaceae, Staphylococcus aureus, Haemophilus influenzae, Streptococcus pneumoniae, Burkholderia cepacia, and Candida species were commonly isolated from early onset VAP. Polymicrobial infections occurred in 14 cases, so overall 43 VAP pathogens were isolated. Thirty (69.7% of them were multidrug resistant (MDR, among which ESBL contributed 23.25%, MBL 30.23%, AmpC beta-lactamases 9.30%, and to methicillin resistant S. aureus (MRSA contributed 6.97%. Prior antibiotic therapy (P < 0.0001, hospitalization for 5 days or more (P < 0.0001, MV for 5 days or more (P < 0.0001, supine head position (P < 0.0001, reintubation (P = 0.0012, and impaired consciousness (P = 0.0191 were significant risk factors for VAP. Conclusions: Proper knowledge of risk factors can help identify high risk groups for VAP, among the critically

    Despite the rapid growth of social franchising, there is little evidence on its population impact in the health sector. Similar in many ways to private-sector commercial franchising, social franchising can be found in sectors with a social objective, such as health care. This article evaluates the World Health Partners (WHP) Sky program, a large-scale social franchising and telemedicine program in Bihar, India. We studied appropriate treatment for childhood diarrhea and pneumonia and associated health care outcomes. We used multivariate difference-in-differences models to analyze data on 67,950 children ages five and under in 2011 and 2014. We found that the WHP-Sky program did not improve rates of appropriate treatment or disease prevalence. Both provider participation and service use among target populations were low. Our results do not imply that social franchising cannot succeed; instead, they underscore the importance of understanding factors that explain variation in the performance of social franchises. Our findings also highlight, for donors and governments in particular, the importance of conducting rigorous impact evaluations of new and potentially innovative health care delivery programs before investing in scaling them up.

    Globally, pneumonia is the leading cause of childhood mortality. Pneumonia is the second killer of children less than 5 years of age in China. The World Heath Organization and United Nations Children's Fund launched the integrated Global Action Plan for the Prevention and Control of Pneumonia and Diarrhea (GAPPD) in 2013. The ambitious goal is to end preventable childhood deaths due to pneumonia by 2025. Countries or regions should achieve the following goals:(1) reduce mortality from pneumonia in children less than 5 years of age to fewer than 3 per 1 000 live births;(2) reduce the incidence of severe pneumonia by 75%in children less than 5 years of age compared to 2010 levels. If the implementation of key interventions is accelerated, the mortality rate of childhood pneumonia will drop substantially every year, which makes the goal achievable.%肺炎是全球儿童死亡的首位原因,也是我国5岁以下儿童死亡的第二位原因。世界卫生组织和联合国儿童基金会2013年发布了预防和控制肺炎和腹泻全球行动计划,提出了控制儿童肺炎的宏伟目标:2025年彻底避免儿童期肺炎可预防性死亡。在国家或地区层面上要实现:(1)5岁以下儿童肺炎死亡率低于3/1000活产儿;(2)与2010年比较,5岁以下严重肺炎的发生率下降75%。如能加快执行关键干预措施的步伐,儿童肺炎的死亡率会明显下降,目标就能实现。[中国当代儿科杂志,2014,16(10):967-969

    There are few published reports on the unique nature of burn patients using a paired spontaneous awakening and spontaneous breathing protocol. A combined protocol was implemented in our burn intensive care unit (ICU) on January 1, 2012. This study evaluates the impact of this protocol on patient outcomes in a burn ICU. We performed a retrospective review of our burn registry over 4 years, including all patients placed on mechanical ventilation. In the latter 2 years, patients meeting criteria underwent daily spontaneous awakening trial; if successful, spontaneous breathing trial was performed. Patient data included age, burn size, percent full-thickness burn, tracheostomy, and inhalation injury. Outcome measures included ventilator days, ICU and hospital lengths of stay, pneumonia, and disposition. Data were analyzed using Graphpad Prism and IBM SPSS software, with statistical significance defined as P < .05. There were 171 admissions in the preprotocol period and 136 after protocol implementation. Protocol patients had greater percent full-thickness burns, but did not differ in other characteristics. The protocol group had significantly shorter ICU length of stay, fewer ventilator days, and lower pneumonia incidence. Hospital length of stay, disposition, and mortality were not significantly different. Among patients with inhalation injuries, the protocol group exhibited fewer ventilator and ICU days. Protocol implementation in a burn ICU was accompanied by decreased ventilator days and a reduced incidence of pneumonia. A combined spontaneous awakening and breathing protocol is safe and may improve clinical practice in the burn ICU.

    Full Text Available A pneumonia é a infecção nosocomial mais comum em unidades de terapia intensiva, sendo a ventilação mecânica um fator fortemente associado ao seu desenvolvimento. O objetivo deste estudo foi descrever o impacto do sistema de aspiração traqueal aberto e fechado na incidência de pneumonia associada à ventilação mecânica. Realizou-se uma pesquisa na base de dados Pubmed para identificar tentativas controladas aleatórias, publicadas no período de 1990 a novembro de 2008. Nove estudos foram incluídos. Dos estudos revisados, sete não observaram redução significante da incidência de pneumonia associada à ventilação mecânica com o uso do sistema fechado comparado ao aberto, sendo que dois destes verificaram que o uso do sistema fechado resulta em incremento nas taxas de colonização sem incrementar sua incidência e um observou que o uso do sistema fechado não incrementa a colonização do trato respiratório e reduz a expansão de infecção resultando em redução nas taxas de sepse. Apenas dois estudos verificaram redução na incidência de pneumonia associada à ventilação mecânica com o uso do sistema fechado, e um destes revelou um risco 3.5 vezes maior de desenvolvimento desta infecção com o sistema aberto. Os resultados sugerem que o impacto do sistema de aspiração traqueal aberto e fechado é semelhante para o desenvolvimento da pneumonia associada à ventilação mecânica, assim a escolha do tipo de sistema de aspiração traqueal deve ser baseada em outros parâmetros. Entretanto, o sistema fechado aumenta o risco de colonização do trato respiratório, mas apresenta como vantagens a manutenção da ventilação mecânica e o menor prejuízo hemodinâmico.Pneumonia is the most common nosocominal infection in intensive care units and mechanical ventilation is a significant factor associated to its development.

    2012-05-01

    Full Text Available Abstract The first case–control study on mobile phone use and brain tumour risk among children and adolescents (CEFALO study has recently been published. In a commentary published in Environmental Health, Söderqvist and colleagues argued that CEFALO suggests an increased brain tumour risk in relation to wireless phone use. In this article, we respond and show why consistency checks of case–control study results with observed time trends of incidence rates are essential, given the well described limitations of case–control studies and the steep increase of mobile phone use among children and adolescents during the last decade. There is no plausible explanation of how a notably increased risk from use of wireless phones would correspond to the relatively stable incidence time trends for brain tumours among children and adolescents observed in the Nordic countries. Nevertheless, an increased risk restricted to heavy mobile phone use, to very early life exposure, or to rare subtypes of brain tumours may be compatible with stable incidence trends at this time and thus further monitoring of childhood brain tumour incidence rate time trends is warranted.

    Full Text Available Abstract Background Spatial cluster detection is an important tool in cancer surveillance to identify areas of elevated risk and to generate hypotheses about cancer etiology. There are many cluster detection methods used in spatial epidemiology to investigate suspicious groupings of cancer occurrences in regional count data and case-control data, where controls are sampled from the at-risk population. Numerous studies in the literature have focused on childhood leukemia because of its relatively large incidence among children compared with other malignant diseases and substantial public concern over elevated leukemia incidence. The main focus of this paper is an analysis of the spatial distribution of leukemia incidence among children from 0 to 14 years of age in Ohio from 1996–2003 using individual case data from the Ohio Cancer Incidence Surveillance System (OCISS. Specifically, we explore whether there is statistically significant global clustering and if there are statistically significant local clusters of individual leukemia cases in Ohio using numerous published methods of spatial cluster detection, including spatial point process summary methods, a nearest neighbor method, and a local rate scanning method. We use the K function, Cuzick and Edward's method, and the kernel intensity function to test for significant global clustering and the kernel intensity function and Kulldorff's spatial scan statistic in SaTScan to test for significant local clusters. Results We found some evidence, although inconclusive, of significant local clusters in childhood leukemia in Ohio, but no significant overall clustering. The findings from the local cluster detection analyses are not consistent for the different cluster detection techniques, where the spatial scan method in SaTScan does not find statistically significant local clusters, while the kernel intensity function method suggests statistically significant clusters in areas of central, southern

    To investigate the epidemiological characteristics of childhood type 1 diabetes mellitus in China, newly diagnosed cases of type 1 diabetes with an onset age under 15 years were retrospectively registered by 23 local centers in China following a standardized protocal on the basis of the nationwide registry established by the WHO DiaMond Project China Participating Center, Chinese Academy of Preventive Medicine (CAPM). A population of about 24 million children were covered in the defined areas . A two-sample capture-recapture method was used to estimate case ascertainment. Between 1988 and 1996, 903 diabetic cases were registered in 9 ethnic groups. The overall ascertainment corrected incidence rate (IR) was 0.59 per 100 000 person-year. The IR was 0.52/100,000(95%CI:0.50~0.54)for males and 0.66/100,000(95%CI:0.64~0.68)for females. The standardized ascertainment corrected IR by the national age-specific population in 1990 was 0.57 per 100,000 person-year. The incidence among various ethnic groups ranged from 0.25/100,000 to 3.06/100,000. The IRs increased with northern latitude, and the IR of Han population was significantly higher in North China compared with South China (0.67 versus 0.53 per 100,000 respectively, P<0.01). A correlation model of incidence and calendar time showed that the IR increased significantly between 1988 and 1996 (r=0.86, P=0.0027). The relative risk (RR) of type 1 diabetes mellitus for different age-groups estimated by a Poisson regression model showed that taking RR as 1.00 for age-group from 0 to 4 years, the RR for age-group from 5 to 9 year and from 10 to 14 year was 2.30 and 3.60 respectively. The standardized ascertainment corrected IR of childhood type 1 diabetes mellitus in China is much lower than in other countries. The geographic and ethnic variability of the incidence suggests that both genetic and environmental factors play a role in the development of childhood diabetes in China.

    Full Text Available Background: Ventilator-associated pneumonia (VAP is an important intensive care unit (ICU infection in mechanically ventilated patients. VAP occurs approximately in 9-27% of all intubated patients. Due to the increasing incidence of multidrug-resistant organisms in ICUs, early and correct diagnosis of VAP is an urgent challenge for an optimal antibiotic treatment. Aim of the Study: The aim of the study was to assess the incidence of VAP caused by multidrug-resistant organisms in the multidisciplinary intensive care unit (MICU of our tertiary care 1,400-bedded hospital. Materials and Methods: This prospective study was done in the period from December 2005 to August 2006, enrolling patients undergoing mechanical ventilation (MV for> 48 h. Endotracheal aspirates (ETA were collected from patients with suspected VAP, and quantitative cultures were performed on all samples. VAP was diagnosed by the growth of pathogenic organism _10 5 cfu/ml. Results: Incidence of VAP was found to be 45.4% among the mechanically ventilated patients, out of which 47.7% had early-onset (< 5 days MV VAP and 52.3% had late-onset (>5 days MV VAP. Multiresistant bacteria, mainly Acinetobacter spp. (47.9% and Pseudomonas aeruginosa (27%, were the most commonly isolated pathogens in both types of VAP. Most of the isolates of Escherichia coli (80% and Klebsiella pneumoniae (100% produced extended-spectrum beta lactamases (ESBLs. As many as 30.43% isolates of Acinetobacter spp. showed production of AmpC beta lactamases among all types of isolates. Metallo-beta lactamases (MBLs were produced by 50% of Pseudomonas aeruginosa and 21.74% of Acinetobacter spp. Conclusion : High incidence (45.4% of VAP and the potential multidrug-resistant organisms are the real threat in our MICU. This study highlighted high incidence of VAP in our setup, emphasizing injudicious use of antimicrobial therapy. Combined approaches of rotational antibiotic therapy and education programs might be

    Full Text Available This study aims to describe childhood tuberculosis incidence in Southeast Brazil in 1996. It is a descriptive study based on secondary records from the Tuberculosis Division of the São Paulo State Health Department. The study area includes 40 cities, has some 1,800,000 inhabitants, and is located between São Paulo and Rio de Janeiro, the largest cities in Brazil. The study included cases up to 15 years of age. Independent variables were: sex, age, type of case, clinical presentation, radiology, AFB microscopy, HIV antibody tests, and method of discovery. The incidence rate in this age bracket was 10.4/100,000. Pulmonary manifestations were the most common, and control of contacts was the most common method of case discovery. AFB microscopy was performed in 18.6% of the cases and HIV testing was done in 14.9%. Incidence in this study was higher than for the State of São Paulo as a whole. Poor socioeconomic level, deterioration of public health services, treatment dropout by adults and their persistence as sputum-positive carriers, and flaws in case reporting and follow-up could explain these results.O objetivo deste estudo é descrever a incidência de tuberculose na infância, no Sudeste do Brasil.

    Background While the pentavalent rotavirus vaccine was highly efficacious against rotavirus diarrhea in clinical trials, the vaccine’s effectiveness under field conditions in the developing world is unclear. In October, 2006, Nicaragua became the first developing nation to implement universal infant immunization with the pentavalent rotavirus vaccine. To assess the impact of the immunization program, we examined the incidence of diarrhea episodes between 2003 and 2009 among children in the state of León, Nicaragua. Methods We extracted data on diarrhea episodes from health ministry records. We used scaled Poisson regression models to estimate diarrhea incidence rate ratios (IRR) for the period following the program’s implementation to the period before implementation. Results Following implementation of the immunization program, diarrhea episodes among infants were reduced (IRR 0.85, 95% confidence interval [CI] 0.71–1.02) during the rotavirus season, but appear to have increased during other months. Conclusions While the immunization program appears effective in reducing diarrhea episodes during the rotavirus season, a large burden of diarrhea persists during the remainder of the year.

    Purpose Recent genome-wide screens have identified genetic variations in ARID5B associated with susceptibility to childhood acute lymphoblastic leukemia (ALL). We sought to determine the contribution of ARID5B single nucleotide polymorphisms (SNPs) to racial disparities in ALL susceptibility and treatment outcome. Patients and Methods We compared the association between ARID5B SNP genotype and ALL susceptibility in whites (> 95% European genetic ancestry; 978 cases and 1,046 controls) versus in Hispanics (> 10% Native American ancestry; 330 cases and 541 controls). We determined the relationships between ARID5B SNP genotype and ALL relapse risk in 1,605 children treated on the Children's Oncology Group (COG) P9904/9905 clinical trials. Results Among 49 ARID5B SNPs interrogated, 10 were significantly associated with ALL susceptibility in both whites and Hispanics (P < .05), with risk alleles consistently more frequent in Hispanics than in whites. rs10821936 exhibited the most significant association in both races (P = 8.4 × 10−20 in whites; P = 1 × 10−6 in Hispanics), and genotype at this SNP was highly correlated with local Native American genetic ancestry (P = 1.8 × 10−8). Multivariate analyses in Hispanics identified an additional SNP associated with ALL susceptibility independent of rs10821936. Eight ARID5B SNPs were associated with both ALL susceptibility and relapse hazard; the alleles related to higher ALL incidence were always linked to poorer treatment outcome and were more frequent in Hispanics. Conclusion ARID5B polymorphisms are important determinants of childhood ALL susceptibility and treatment outcome, and they contribute to racial disparities in this disease. PMID:22291082

    Full Text Available We aimed to evaluate sociodemographic, epidemiological, and clinical risk factors for pulmonary tuberculosis (PTB in children presenting with severe acute malnutrition (SAM and pneumonia. Children aged 0 to 59 months with SAM and radiologic pneumonia from April 2011 to July 2012 were studied in Bangladesh. Children with confirmed PTB (by culture and/or X-pert MTB/RIF (cases = 27 and without PTB (controls = 81; randomly selected from 378 children were compared. The cases more often had the history of contact with active PTB patient (P < .01 and exposure to cigarette smoke (P = .04 compared with the controls. In logistic regression analysis, after adjusting for potential confounders, the cases were independently associated with working mother (P = .05 and positive tuberculin skin test (TST; P = .02. Thus, pneumonia in SAM children is a common presentation of PTB and further highlights the importance of the use of simple TST and/or history of contact with active TB patients in diagnosing PTB in such children, especially in resource-limited settings.

    Full Text Available Background: In this study, the history of viral infections of measles, chickenpox and mumps in childhood was compared between the two groups of adults with multiple sclerosis (MS and healthy people. Materials and Methods: In this case-control study, a group of 45 MS patients and a group of 135 healthy people who were similar based on some variables were invited. Patients had a definite diagnosis of MS and control group consisted of people accompanying MS patients. Data were collected by a trained expert in face-to-face interview sessions. For data analysis, odds ratio index was calculated and 95% confidence interval was also computed. The mean age of respondents at the time of viral infections was also compared between the two groups.Results: The proportions of infected people by measles, chickenpox and mumps among MS patients were 58%, 56% and 40%, respectively. These proportions in healthy group were 68%, 52% and 44%, respectively. There was not any significant difference between these proportions in the two groups. Mean age of morbidity for measles, chickenpox and mumps among patients were 6.8±3.1, 8.7±2.98 and 10.6±4.7 years, and were significantly higher that these mean ages (4.1±2.1, 5.3±3.1 and 8.4±2.8, respectively among healthy people (p<0.001.Conclusion: Although there was not any significant difference between the history of morbidity of measles, chickenpox and mumps in the two groups of MS patients and healthy people, the mean ages of these viral infections among MS patients were significantly higher than healthy people.

    Background and Purpose: Radiotherapy is an integral part of various therapeutic regimens in pediatric and adult oncology. Endocrine dysfunction, neurologic and psychiatric deficits, secondary malignancies and radiation-induced necrosis are well-known possible late effects of cranial irradiation. However, only sporadic cases of radiation-induced cavernous hemangiomas (RICH) have been reported so far. Patients and Methods: Pediatric patients who underwent cranial radiation therapy for malignant diseases between January 1980 and December 2003 were retrospectively analyzed. After the end of therapy they entered a detailed follow-up program. Results: Of 171 patients, eight (three patients with medulloblastoma, three patients with acute lymphoblastic leukemia, and one patient each with ependymoma and craniopharyngioma) developed intracerebral cavernoma 2.9-18.4 years after irradiation representing a cumulative incidence (according to the Kaplan-Meier method) of 2.24%, 3.86%, 4.95%, and 6.74% within 5, 10, 15, and 20 years following radiation therapy, respectively. In patients treated in the first 10 years of life, RICH occurred with shorter latency and significantly more often (p = 0.044) resulting in an even higher cumulative incidence. Conclusion: These findings and previously published cases show that cavernous hemangiomas may occur after irradiation of the brain several years after the end of therapy irrespective of the radiation dose and type of malignancy. Particularly children < 10 years of age at the time of irradiation are at higher risk. Since patients with RICH frequently do not show symptoms but hemorrhage is a possible severe complication, imaging of the central nervous system should be performed routinely for longer follow- ups, particularly in patients who were treated as young children.

    Full Text Available Abstract Background Millions of children die every year in developing countries, from preventable diseases such as pneumonia and diarrhoea, owing to low levels of investment in child health. Investment efforts are hampered by a general lack of adequate information that is necessary for priority setting in this sector. This paper measures the health system costs of providing inpatient and outpatient services, and also the costs associated with treating pneumonia and diarrhoea in under-five children at a health centre in Zambia. Methods Annual economic and financial cost data were collected in 2005-2006. Data were summarized in a Microsoft excel spreadsheet to obtain total department costs and average disease treatment costs. Results The total annual cost of operating the health centre was US$1,731,661 of which US$1 284 306 and US$447,355 were patient care and overhead departments costs, respectively. The average cost of providing out-patient services was US$3 per visit, while the cost of in-patient treatment was US$18 per bed day. The cost of providing dental services was highest at US$20 per visit, and the cost of VCT services was lowest, with US$1 per visit. The cost per out-patient visit for under-five pneumonia was US$48, while the cost per bed day was US$215. The cost per outpatient visit attributed to under-five diarrhoea was US$26, and the cost per bed day was US$78. Conclusion In the face of insufficient data, a cost analysis exercise is a difficult but feasible undertaking. The study findings are useful and applicable in similar settings, and can be used in cost effectiveness analyses of health interventions.

    Results: Overall incidence of VAP was 23.54 per 1,000 ventilator days. The incidence of VAP in MICU and CCU were 31.77 and 16.47 per 1,000 ventilator days respectively. 60% of the cases were late-onset VAP, while 40% were early-onset VAP. The most common organism isolated was Pseudomonas aeruginosa followed by Methicillin-resistant Staphylococcus aureus (MRSA. Impaired consciousness, tracheostomy, re-intubation, emergency intubation, and nasogastric tube were significantly associated with VAP. On multivariate analysis, impaired consciousness, emergency intubation and tracheostomy were independent risk factor for VAP among study subjects. Conclusions: Data thus generated can be used to plan and modulate the potential intervention measures while managing VAP. Knowledge of the important risk factors predisposing to VAP may prove to be useful in implementing effective preventive measures. [Int J Res Med Sci 2016; 4(5.000: 1692-1697

    Opportunistic infection with Pneumocystis jiroveci pneumonia (PCP) has not been recognized as a significant complication of early-stage breast cancer treatment. However, we have observed an increase in PCP incidence among patients receiving chemotherapy for early-stage breast cancer. Herein we identify risk factors for and calculate incidence of PCP in this population. We identified all cases of PCP at Dana-Farber Cancer Institute/Brigham and Women's Hospital (DFCI/BWH) from 1/1/2000 to 12/31/2013 in patients with stage I-III breast cancer treated with an adriamycin/cyclophosphamide (AC)-containing regimen. Nineteen cases of PCP in non-metastatic breast cancer patients were identified. All patients with PCP were diagnosed after receipt of either three or four cycles of AC chemotherapy on a dose-dense schedule. Patients who developed PCP were treated with median 16.4 mg prednisone equivalents/day as nausea prophylaxis for a median 64 days. The overall incidence of PCP among 2057 patients treated with neoadjuvant or adjuvant dose-dense AC for three or more cycles was 0.6 % (95 % confidence interval 0.3-1.0 %). No PCP was diagnosed in 1001 patients treated with non-dose-dense AC. There was one death from PCP. Women receiving dose-dense AC chemotherapy for early-stage breast cancer are at risk for PCP. Administering the same chemotherapy and corticosteroid dose over an 8-week versus 12-week non-dose-dense schedule appears to have created a novel infectious vulnerability. Replacing dexamethasone with alternative anti-emetics may mitigate this risk.

    Full Text Available BACKGROUND: The natural history of HIV infection has changed dramatically after the introduction of highly active antiretroviral therapy. Currently, opportunistic illnesses still represent a major cause of death and hospitalization in this population. In this study, we review the trends in opportunistic illnesses incidence rates and compare the results observed in high-income settings with that for low/middle-income settings, with special attention given to studies from Brazil. METHODS: We systematically searched Pubmed, Web of Science, Lilacs and Google scholar for publications on HIV associated opportunistic illness. Studies reporting rates based on person-time for all opportunistic illnesses and/or the three opportunistic infections of interest, namely,Pneumocystis carinii pneumonia, cerebral toxoplasmosis, and Mycobacterium avium complex were included. RESULTS: Significant reductions in the incidence rates were demonstrated for opportunistic illnesses overall and also for the specific opportunistic infections included in the present study, both in high and low/middle-income settings. Out of the 37 studies included in the present review, almost 70% were from high-income settings. All the studies conducted in low/middle-income settings were single center studies and four were from Brazil. We found no study from Brazil reporting annual incidence rates of opportunistic illnesses. CONCLUSIONS: Opportunistic illnesses remain an important public health problem. To better guide health policies in low/middle-income settings, multicenter cohort studies should be encouraged. Studies from Brazil are urgently needed to assess the current burden of opportunistic illnesses in our population and to support the planning of HIV/AIDS health care services organization.

    Full Text Available Abstract Background Where hard-to-access populations (such as those living in insecure areas lack access to basic health services, relief agencies, donors, and ministries of health face a dilemma in selecting the most effective intervention strategy. This paper uses a decision mathematical model to estimate the relative effectiveness of two alternative strategies, mobile clinics and fixed community-based health services, for antibiotic treatment of childhood pneumonia, the world's leading cause of child mortality. Methods A "Markov cycle tree" cohort model was developed in Excel with Visual Basic to compare the number of deaths from pneumonia in children aged 1 to 59 months expected under three scenarios: 1 No curative services available, 2 Curative services provided by a highly-skilled but intermittent mobile clinic, and 3 Curative services provided by a low-skilled community health post. Parameter values were informed by literature and expert interviews. Probabilistic sensitivity analyses were conducted for several plausible scenarios. Results We estimated median pneumonia-specific under-5 mortality rates of 0.51 (95% credible interval: 0.49 to 0.541 deaths per 10,000 child-days without treatment, 0.45 (95% CI: 0.43 to 0.48 with weekly mobile clinics, and 0.31 (95% CI: 0.29 to 0.32 with CHWs in fixed health posts. Sensitivity analyses found the fixed strategy superior, except when mobile clinics visited communities daily, where rates of care-seeking were substantially higher at mobile clinics than fixed posts, or where several variables simultaneously differed substantially from our baseline assumptions. Conclusions Current evidence does not support the hypothesis that mobile clinics are more effective than CHWs. A CHW strategy therefore warrants consideration in high-mortality, hard-to-access areas. Uncertainty remains, and parameter values may vary across contexts, but the model allows preliminary findings to be updated as new or context

    Full Text Available Zinc is an essential nutrient particularly important for growing children and for those who experience frequent infections. Many children in developing countries have inadequate zinc nutrition that impairs their immune system. Diarrhea and pneumonia are among the leading causes of morbidity and mortality in children of low-income countries. Zinc deficiency increases the susceptibility to these infections and administration of zinc to children with diarrhea and, possibly, pneumonia speeds up recovery. Furthermore, zinc given to otherwise healthy children also reduces the incidence of diarrhea and pneumonia. Thus, thousands of lives can be saved every year by giving zinc to prevent childhood infections or by providing zinc to children with ongoing infections. This paper gives a brief outline of the history of zinc research and reviews existing evidence from clinical trials on the prophylactic and therapeutic effect of oral zinc on childhood pneumonia and diarrhea

    és de este artículo está disponible en: http://www.insp.mx/salud/index.htmlObjective. To determine the incidence of catheter-related bacteremia and ventilator-associated pneumonia in children admitted to a secondary care hospital. Material and Methods. A prospective active surveillance system was conducted from January 1999 to June 2000, at the Hospital General of Instituto Mexicano del Seguro Social in Durango, Mexico. Daily visits to the pediatric ward were conducted to detect episodes of bacteremia and pneumonia, according to the Official Mexican Norm. Hospitalized patients under mechanical ventilation and/or with a central venous catheter, were followed from the first day of exposure, until a nosocomial infection was detected, or until the invasive device was removed. Blood and tracheal aspirate cultures were obtained from all exposed patients. Incidence rates with 95% confidence intervals were calculated for ventilator-associated pneumonia and bacteremia/sepsis per 1000 exposure days. Also, the monthly infection rate is presented for days of exposure, using statistical control graphs. Results. A total of 47 episodes of bacteremia/sepsis and 44 of ventilator associated pneumonia were recorded. The incidence rate of pneumonia and bacteremia/sepsis was 28 and 26 cases respectively, per 1000 days of exposure to and invasive device. The gram-positive rods (61.11% were more common than the gram negative rods (38.88%. Conclusions. The most striking finding of this study was the higher incidence of these two nosocomial infections in children, as compared to that reported elsewhere. These findings call for preventive strategies and guidelines for handling intravenous catheters and mechanical ventilation in Mexico.

    Childhood abuse has been recognized as a precursor and a maintaining factor for adult psychopathology. There are very few studies that have investigated the incidence of childhood abuse in adult women with psychiatric disorders. Hence, this current investigation is an attempt to study and compare the incidence of childhood abuse (physical, emotional and sexual) among women seeking treatment for psychiatric disorders to healthy women. Using consecutive sampling, women seeking treatment for psychiatric disorders (N=609) and a group of age-education matched healthy women (N=100) were recruited for the study from a tertiary mental health-care hospital in India. The participants were screened for childhood abuse using the ISPCAN Child Abuse Screening Tool - Retrospective (ICAST)-R (I-CAST R, International Society for the Prevention of Child Abuse and Neglect (ISPCAN) and The United Nations Children's Fund (UNICEF), 2009). Emotional abuse was significantly more common among women with psychiatric disorders compared with healthy women (p0.13). There was no statistically significant difference in all three types of abuse across disorder categories, though the report was more among women with severe mental disorders. Women with psychiatric disorders reported more emotional and overall abuse compared with healthy women. Sexual and physical abuse was similar in both groups. It is likely that more emotional abuse predisposes these women to psychiatric disorders.

    Extrapulmonary manifestations of Mycoplasma pneumoniae are well described, including a subset of central nervous system (CNS)-associated syndromes. In pediatric populations, frequencies of CNS sequelae occur in 0.1% to 7% of patients. Neurologic illness associated with M. pneumoniae, such as meningitis, encephalitis, polyradiculitis, Guillain-Barre, and stroke have been reported; however, the incidence of M. pneumoniae-associated organic brain syndrome is rare. We present the case of a 20-year-old midshipman with acute psychosis following resolution of M. pneumoniae pneumonia and review 6 other adult cases found in the literature. M. pneumoniae remains one of the most common causes of respiratory illnesses in the military recruit setting and therefore should always be suspected as an organic cause of mental status changes in young persons such as recruits, cadets, and midshipmen particularly with antecedent respiratory illnesses.

    Full Text Available Abstract Background Pneumonia is among the main causes of illness and death in children Methods From July 2004 to June 2007, we examined nasopharyngeal aspirates (NPA from 2,230 cases of pneumonia (World Health Organization criteria in children 2 to 35 months old recruited in a randomized trial of zinc supplementation at a field clinic in Bhaktapur, Nepal. The specimens were examined for respiratory syncytial virus (RSV, influenza virus type A (InfA and B (InfB, parainfluenza virus types 1, 2 and 3 (PIV1, PIV2, and PIV3, and human metapneumovirus (hMPV using a multiplex reverse transcriptase polymerase chain reaction (PCR assay. Results We identified 919 virus isolates in 887 (40.0% of the 2,219 NPA specimens with a valid PCR result, of which 334 (15.1% yielded RSV, 164 (7.4% InfA, 129 (5.8% PIV3, 98 (4.4% PIV1, 93 (4.2% hMPV, 84 (3.8% InfB, and 17 (0.8% PIV2. CAP occurred in an epidemic pattern with substantial temporal variation during the three years of study. The largest peaks of pneumonia occurrence coincided with peaks of RSV infection, which occurred in epidemics during the rainy season and in winter. The monthly number of RSV infections was positively correlated with relative humidity (rs = 0.40, P = 0.01, but not with temperature or rainfall. An hMPV epidemic occurred during one of the three winter seasons and the monthly number of hMPV cases was also associated with relative humidity (rs = 0.55, P = 0.0005. Conclusion Respiratory RNA viruses were detected from NPA in 40% of CAP cases in our study. The most commonly isolated viruses were RSV, InfA, and PIV3. RSV infections contributed substantially to the observed CAP epidemics. The occurrence of viral CAP in this community seemed to reflect more or less overlapping micro-epidemics with several respiratory viruses, highlighting the challenges of developing and implementing effective public health control measures.

    Health care associated infections, the fourth leading cause of disease in industrialised countries, are a major health issue. One part of this condition is based on the increasing insertion and implantation of prosthetic medical devices, since presence of a foreign body significantly reduces the number of bacteria required to produce infection. The most significant hospital-acquired infections, based on frequency and potential severity, are those related to procedures e.g. surgical site infections and medical devices, including urinary tract infection in catheterized patients, pneumonia in patients intubated on a ventilator and bacteraemia related to intravascular catheter use. At least half of all cases of nosocomial infections are associated with medical devices.Modern medical and surgical practices have increasingly utilized implantable medical devices of various kinds. Such devices may be utilized only short-time or intermittently, for months, years or permanently. They improve the therapeutic outcome, save human lives and greatly enhance the quality of life of these patients. However, plastic devices are easily colonized with bacteria and fungi, able to be colonized by microorganisms at a rate of 0.5 cm per hour. A thick biofilm is formed within 24 hours on the entire surface of these plastic devices once inoculated even with a small initial number of bacteria.The aim of the present work is to review the current literature on causes, frequency and preventive measures against infections associated with intravascular devices, catheter-related urinary tract infection, ventilator-associated infection, and infections of other implantable medical devices. Raising awareness for infection associated with implanted medical devices, teaching and training skills of staff, and establishment of surveillance systems monitoring device-related infection seem to be the principal strategies used to achieve reduction and prevention of such infections.

    Full Text Available BACKGROUND: Pneumonia is a major cause of childhood mortality and morbidity approximately 1.6 million deaths and 150 million episodes occur annually in children <5 years. Respiratory syncytial virus (RSV may be responsible for up to 25% of cases and 12% of deaths making it an important potential vaccine target, although data from South East Asia is scarce. METHODS: We followed a birth cohort of Burmese refugee children, born over a one year period, for two years. Pneumonia episodes were diagnosed using WHO criteria. A chest radiograph, nasopharyngeal aspirate and non-specific markers of infection were taken during each episode. RESULTS: The incidence of RSV-associated pneumonia was 0.24 (95% CI 0.22-0.26 episodes per child year. All children with pneumonia received antibiotic treatment, following WHO guidelines. The highest incidence was in the 2-12 month age group. The commonest diagnosis in a child with RSV-associated pneumonia was non-severe pneumonia (239/362:66.0%, however the incidence of RSV-associated severe or very severe pneumonia was 0.08 (95% CI 0.01-0.10 episodes per child year. Birth in the wet season increased the risk of severe disease in children who had their first episode of RSV-associated pneumonia aged 2-11 months (OR 28.7, 95% CI 6.6-125.0, p<0.001. RSV episodes were highly seasonal being responsible for 80.0% of all the pneumonia episodes occurring each October and November over the study period. CONCLUSIONS: There was a high incidence of RSV associated pneumonia in this refugee population. Interventions to prevent RSV infection have the potential to reduce the incidence of clinically diagnosed pneumonia and hence unnecessary antibiotic usage in this population.

    Among various methods for preventing ventilator-associated pneumonia (VAP), the evidence base for selective digestive decontamination (SDD) appears most compelling. However, the extent of Staphylococcus aureus emergence with SDD use remains uncertain. Groups from 37 observational studies and component (control and intervention) groups from 58 studies of SDD and other methods of VAP prevention were sourced exclusively from 10 systematic reviews. S. aureus as a proportion of VAP isolates (S. aureus isolate proportion [S. aureus IP]) among component groups was calibrated versus that among observational groups (the benchmark). The influence of topical placebo used for blinding purposes and other group-level factors was estimated using generalized estimating equation methods (GEE). The mean S. aureus IP is 22% (95% confidence interval [CI], 19 to 25) for 37 observational groups versus 32% (24 to 41) and 20% (15 to 25) for 22 control groups from the SDD evidence base which did versus did not receive topical placebo, respectively. In GEE models including all 148 observational and component groups, membership of a control (P = 0.03) or intervention (P placebo was associated with higher S. aureus IP, whereas, in contrast, membership of these groups was without effect on Pseudomonas aeruginosa. Topical placebo is implicated as a vehicle for selective cross-infection with S. aureus within the specific context of the SDD evidence base. This effect of topical placebo is perfidious; it could contribute to the higher VAP incidence and inflate the apparent "effectiveness" of SDD. The SDD evidence base requires reappraisal.

  13. A compendium for Mycoplasma pneumoniae

    Full Text Available Historically, atypical pneumonia was a term used to describe an unusual presentation of pneumonia. Currently, it is used to describe the multitude of symptoms juxtaposing the classic symptoms found in cases of pneumococcal pneumonia. Specifically, atypical pneumonia is a syndrome resulting from a relatively common group of pathogens including Chlamydophila sp., and Mycoplasma pneumoniae. The incidence of M. pneumoniae pneumonia in adults is less than the burden experienced by children. Transmission rates among families indicate children may act as a reservoir and maintain contagiousness over a long period of time ranging from months to years. In adults, M. pneumoniae typically produces a mild, walking pneumonia and is considered to be one of the causes of persistent cough in patients. M. pneumoniae has also been shown to trigger the exacerbation of other lung diseases. It has been repeatedly detected in patients with bronchitis, asthma, chronic obstructive pulmonary disorder and cystic fibrosis. Recent advances in technology allow for the rapid diagnosis of M. pneumoniae through the use of polymerase chain reaction (PCR or rapid antigen tests. With this, more effort has been afforded to identify the causative etiologic agent in all cases of pneumonia. However, previous practices, including the overprescribing of macrolide treatment in China and Japan, have created increased incidence of macrolide-resistant M. pneumoniae. Reports from these countries indicate that >85% of M. pneumoniae pneumonia pediatric cases are macrolide-resistant. Despite its extensively studied past, the smallest bacterial species still inspires some of the largest questions. The developments in microbiology, diagnostic features and techniques, epidemiology, treatment and vaccines, and upper respiratory conditions associated with M. pneumoniae in adult populations are included within this review.

    The works presented here constitute the first systematic study of the incidence of childhood leukemia around the whole of French nuclear facilities. Globally, the incidence of childhood leukemia does not diverge significantly of the expected incidence during the period 1990-1998. It does not show a decrease of S.I.R. (standardized incidence ratio) in function of the distance from child's home to the nuclear site whatever be the age. This study represents the first analysis of the incidence of leukemia focusing on 29 French nuclear sites, including the whole of the 19 C.N.P.E. ( nuclear power plants that produce electric power), and is based on incidence data rather than mortality. The period, the age groups and the studied area have been all chosen a priori, that gives a statistical validity to the results. The estimation of population at risk have been made with several different methods of interpolation in order to check the stability of estimations. The different methods of statistical analysis used have lead to extremely close results, reinforcing our confidence in the reliability of our estimations. The excess of leukemia incidence observed at Chinon and Civaux and the deficit observed at Bruyere/Saclay/Fontenay loose their statistical significance when the correction of Bonferroni is applied. So, the global analysis of the 29 sites and the analysis by site have not shown statistically significant difference between the numbers of observed and expected cases. The study of the 19 C.N.P.E. gave same results, even in taken into account their electric power or their year of service. The possibility of confounding factors has been excluded. The power of the study to detect excess incidence and a decrease of S.I.R. with distance from the site was examined under different alternative hypotheses through simulation methods. For values of S.I.R. near the site (0-5 km) between 1.5 and 2 and a risk of error of 5%, the power of the study is between 96% and 100

    Full Text Available Background. Surveillance represents a key strategy to control type 1 diabetes mellitus (T1DM. In Italy, national data are missing. This study aimed at evaluating the incidence of T1DM in subjects <18 year olds in Apulia (a large southeastern region, about 4,000,000 inhabitants and assessing the sensitivity of the regional Registry of Childhood-Onset Diabetes (RCOD in the 2009–2013 period. Methods. We performed a retrospective study matching records from regional Hospital Discharge Registry (HDR, User Fee Exempt Registry (UFER, and Drugs Prescription Registry (DPR and calculated T1DM incidence; completeness of each data source was also estimated. In order to assess the RCOD sensitivity we compared cases from the registry to those extracted from HDR-UFER-DPR matching. Results. During 2009–2013, a total of 917 cases (about 184/year in at least one of the three sources and an annual incidence of 25.2 per 100,000 were recorded, lower in infant, increasing with age and peaked in 5- to 9-year-olds. The completeness of DPR was 78.7%, higher than that of UFER (64.3% and of HDR (59.6%. The RCOD’s sensitivity was 39.05% (360/922; 95% CI: 34.01%–44.09%. Conclusions. Apulia appeared as a high-incidence region. A full, active involvement of physicians working in paediatric diabetes clinics would be desirable to improve the RCOD performance.

    Full Text Available Abstract Background Osteomyelitis can be difficult to diagnose and there has previously not been a prospective approach to identify all children in a defined geographic area. The aim of this study was to assess the annual incidence of osteomyelitis in children, describe the patient and disease characteristics in those with acute ( Methods In a population-based Norwegian study physicians were asked to refer all children with suspected osteomyelitis. Children with osteomyelitis received follow-up at six weeks, six months and thereafter as long as clinically needed. Results The total annual incidence rate of osteomyelitis was 13 per 100 000 (acute osteomyelitis 8 and subacute osteomyelitis 5 per 100 000. The incidence was higher in patients under the age of 3 than in older children (OR 2.9, 95%: CI 2.3–3.7. The incidence of non-vertebral osteomyelitis was higher than the incidence of vertebral osteomyelitis (10 vs. 3 per 100 000; p = .002. Vertebral osteomyelitis was more frequent in girls than in boys (OR 7.0, 95%: CI 3.3–14.7. ESR ≥ 40 mm/hr had the highest positive predictive laboratory value to identify osteomyelitis patients at 26% and MRI had a positive predictive value of 85%. Long-bone infection was found in 16 (43% patients. ESR, CRP, white blood cell count, neutrophils and platelet count were higher for patients with acute osteomyelitis than for patients with subacute osteomyelitis. Subacute findings on MRI and doctor's delay were more common in subacute osteomyelitis than in acute osteomyelitis patients. Blood culture was positive in 26% of the acute osteomyelitis patients and was negative in all the subacute osteomyelitis patients. Conclusion The annual incidence of osteomyelitis in Norway remains high. ESR values and MRI scan may help to identify osteomyelitis patients and differentiate acute and subacute osteomyelitis.

  4. Trends in childhood disease.

    2006-09-28

    Child mortality has declined remarkably during the last decades. While neonatal disorders, diarrhoea, pneumonia, and malaria as well as being underweight account for most of the child deaths worldwide, children's health discussions in Europe and the USA focus on other issues such as asthma, neurodevelopmental disorders, male genital malformations, and childhood cancer. There is clear evidence of increasing rates of asthma in various countries during the last decades, although rates in some countries may now have stabilised or even decline as recent UK data indicate. Although an increase in the frequency of neurodevelopmental disorders such as autism and attention deficit disorder has frequently been discussed, the limited data in this field does not justify such a conclusion. While geographic heterogeneity regarding reproductive outcomes is apparent, global trends have not been identified. Interpretation of the available information on asthma, neurodevelopmental disorders and reproductive outcomes is hampered by inconstant diagnostic criteria over place and time and the lack of good and comprehensive population-based surveillance data, which makes it impossible to ascertain trends in actual disease frequency. Data indicate that developed countries have a gradually increasing incidence in leukaemia with a corresponding drop in the incidence of lymphoma. Increases in brain tumour frequency may be related to the development and wide application of new diagnostic capabilities, rather than a true change in the incidence of malignant disease. With a better prognosis for childhood cancer survival, secondary cancers following chemotherapy appear to be increasing. A wide range of environmental factors is thought to have an impact on children's health. These factors include nutrition (protein, vitamins, antioxidants), lifestyle and behaviour choices such as tobacco and alcohol use, parental health, socio-economic status, choice of living environment (urban versus rural, etc

    This study is concerned with the level of antibiotic resistance of extended-spectrum β-lactamase (ESBL)-producing Klebsiella pneumoniae, isolated in Shantou, China, and its mechanism. Seventyfour non-repetitive clinical isolates of K. pneumoniae producing ESBLs were isolated over a period of 2 years. Antibiotic susceptibility, carried out by Epsilometer test, showed that most of the isolates were multiresistant. Polymerase chain reaction showed that, among the several types of β-lactamases, SHV was the most prevalent, TEM was the second most prevalent, and CTX-M was the least prevalent. Sixty-nine isolates were positive for integrase gene IntI1, but no IntI2 or IntI3 genes were found. The variable region of class 1 integrons were amplified and further identified by sequencing. Thirteen different gene cassettes and 11 different cassette combinations were detected. Dfr and aadA cassettes were predominant and cassette combinations dfrA12, orfF and aadA2 were most frequently found. No gene cassettes encoding ESBLs were found. Integrons were prevalent and played an important role in multidrug resistance in ESBL-producing K. pneumoniae.

    The burden of severe pneumonia in terms of morbidity and mortality is unknown in India especially at sub-national level. In this context, we aimed to estimate the number of severe pneumonia episodes, pneumococcal pneumonia episodes and pneumonia deaths in children younger than 5 years in 2010. We adapted and parameterized a mathematical model based on the epidemiological concept of potential impact fraction developed CHERG for this analysis. The key parameters that determine the distribution of severe pneumonia episode across Indian states were state-specific under-5 population, state-specific prevalence of selected definite pneumonia risk factors and meta-estimates of relative risks for each of these risk factors. We applied the incidence estimates and attributable fraction of risk factors to population estimates for 2010 of each Indian state. We then estimated the number of pneumococcal pneumonia cases by applying the vaccine probe methodology to an existing trial. We estimated mortality due to severe pneumonia and pneumococcal pneumonia by combining incidence estimates with case fatality ratios from multi-centric hospital-based studies. Our results suggest that in 2010, 3.6 million (3.3-3.9 million) episodes of severe pneumonia and 0.35 million (0.31-0.40 million) all cause pneumonia deaths occurred in children younger than 5 years in India. The states that merit special mention include Uttar Pradesh where 18.1% children reside but contribute 24% of pneumonia cases and 26% pneumonia deaths, Bihar (11.3% children, 16% cases, 22% deaths) Madhya Pradesh (6.6% children, 9% cases, 12% deaths), and Rajasthan (6.6% children, 8% cases, 11% deaths). Further, we estimated that 0.56 million (0.49-0.64 million) severe episodes of pneumococcal pneumonia and 105 thousand (92-119 thousand) pneumococcal deaths occurred in India. The top contributors to India's pneumococcal pneumonia burden were Uttar Pradesh, Bihar, Madhya Pradesh and Rajasthan in that order. Our results

    Full Text Available Background: Ventilator-associated pneumonia (VAP is a common complication with endotracheal intubation. The occurrence of VAP results in significant mortality and morbidity. Earlier studies have shown reduction in the incidence of VAP with subglottic secretion drainage. The incidence of VAP in neurologically injured patients is higher and can impact the neurological outcome. This study aimed to compare the incidence of VAP with standard endotracheal tube (SETT and suction above cuff endotracheal tube (SACETT in neurologically ill patients and its impact on clinical outcome. Methods: Fifty-four patients with neurological illnesses aged ≥18 years and requiring intubation and/or ventilation and anticipated to remain on ETT for ≥48 h were randomized to receive either SETT or SACETT. All the VAP preventive measures were similar between two groups except for the difference in type of tube. Results: The data of 50 patients were analyzed. The incidence of clinical VAP was 20% in SETT group and 12% in SACETT group; (P = 0.70. The incidence of microbiological VAP was higher in the SETT group (52% as compared to SACETT group (44% but not statistically significant; (P = 0.78. There was no difference between the two groups for measured outcomes such as duration of intubation, mechanical ventilation, and Intensive Care Unit stay. Conclusions: In this pilot study in neurological population, a there was no significant difference in incidence of clinical and microbiological VAP was seen between SETT and SACETT, when other strategies for VAP prevention were similar. Other outcomes were similar with use of either tube for intubation.

  9. Streptococcus pneumoniae Transmission Is Blocked by Type-Specific Immunity in an Infant Mouse Model

    2017-01-01

    ABSTRACT Epidemiological studies on Streptococcus pneumoniae show that rates of carriage are highest in early childhood and that the major benefit of the pneumococcal conjugate vaccine (PCV) is a reduction in the incidence of nasopharyngeal colonization through decreased transmission within a population. In this study, we sought to understand how anti-S. pneumoniae immunity affects nasal shedding of bacteria, the limiting step in experimental pneumococcal transmission. Using an infant mouse model, we examined the role of immunity (passed from mother to pup) on shedding and within-litter transmission of S. pneumoniae by pups infected at 4 days of life. Pups from both previously colonized immune and PCV-vaccinated mothers had higher levels of anti-S. pneumoniae IgG than pups from non-immune or non-vaccinated mothers and shed significantly fewer S. pneumoniae over the first 5 days of infection. By setting up cross-foster experiments, we demonstrated that maternal passage of antibody to pups either in utero or post-natally decreases S. pneumoniae shedding. Passive immunization experiments showed that type-specific antibody to capsular polysaccharide is sufficient to decrease shedding and that the agglutinating function of immunoglobulin is required for this effect. Finally, we established that anti-pneumococcal immunity and anti-PCV vaccination block host-to-host transmission of S. pneumoniae. Moreover, immunity in either the donor or recipient pups alone was sufficient to reduce rates of transmission, indicating that decreased shedding and protection from acquisition of colonization are both contributing factors. Our findings provide a mechanistic explanation for the reduced levels of S. pneumoniae transmission between hosts immune from prior exposure and among vaccinated children. PMID:28292980

  15. Association of compliance of ventilator bundle with incidence of ventilator-associated pneumonia and ventilator utilization among critical patients over 4 years

    Directory of Open Access Journals (Sweden)

    Majid S Al-Thaqafy

    2014-01-01

    Full Text Available Background: Several studies showed that the implementation of the Institute for Healthcare Improvement (IHI ventilator bundle alone or with other preventive measures are associated with reducing Ventilator-Associated Pneumonia (VAP rates. However, the association with ventilator utilization was rarely examined and the findings were conflicting. The objectives were to validate the bundle association with VAP rate in a traditionally high VAP environment and to examine its association with ventilator utilization. Materials and Methods: The study was conducted at the adult medical-surgical intensive care unit (ICU at King Abdulaziz Medical City, Saudi Arabia, between 2010 and 2013. VAP data were collected by a prospective targeted surveillance as per Centers for Disease Control and Prevention (CDC/National Healthcare Safety Network (NHSN methodology while bundle data were collected by a cross-sectional design as per IHI methodology. Results: Ventilator bundle compliance significantly increased from 90% in 2010 to 97% in 2013 (P for trend < 0.001. On the other hand, VAP rate decreased from 3.6 (per 1000 ventilator days in 2010 to 1.0 in 2013 (P for trend = 0.054 and ventilator utilization ratio decreased from 0.73 in 2010 to 0.59 in 2013 (P for trend < 0.001. There were negative significant correlations between the trends of ventilator bundle compliance and VAP rate (cross-correlation coefficients −0.63 to 0.07 and ventilator utilization (cross-correlation coefficients −0.18 to −0.63. Conclusion: More than 70% improvement of VAP rates and approximately 20% improvement of ventilator utilization were observed during IHI ventilator bundle implementation among adult critical patients in a tertiary care center in Saudi Arabia. Replicating the current finding in multicenter randomized trials is required before establishing any causal link.

    Full Text Available BACKGROUND: Narcolepsy is a chronic sleep disorder with strong genetic predisposition causing excessive daytime sleepiness and cataplexy. A sudden increase in childhood narcolepsy was observed in Finland soon after pandemic influenza epidemic and vaccination with ASO3-adjuvanted Pandemrix. No increase was observed in other age groups. METHODS: Retrospective cohort study. From January 1, 2009 to December 31, 2010 we retrospectively followed the cohort of all children living in Finland and born from January 1991 through December 2005. Vaccination data of the whole population was obtained from primary health care databases. All new cases with assigned ICD-10 code of narcolepsy were identified and the medical records reviewed by two experts to classify the diagnosis of narcolepsy according to the Brighton collaboration criteria. Onset of narcolepsy was defined as the first documented contact to health care because of excessive daytime sleepiness. The primary follow-up period was restricted to August 15, 2010, the day before media attention on post-vaccination narcolepsy started. FINDINGS: Vaccination coverage in the cohort was 75%. Of the 67 confirmed cases of narcolepsy, 46 vaccinated and 7 unvaccinated were included in the primary analysis. The incidence of narcolepsy was 9.0 in the vaccinated as compared to 0.7/100,000 person years in the unvaccinated individuals, the rate ratio being 12.7 (95% confidence interval 6.1-30.8. The vaccine-attributable risk of developing narcolepsy was 1:16,000 vaccinated 4 to 19-year-olds (95% confidence interval 1:13,000-1:21,000. CONCLUSIONS: Pandemrix vaccine contributed to the onset of narcolepsy among those 4 to 19 years old during the pandemic influenza in 2009-2010 in Finland. Further studies are needed to determine whether this observation exists in other populations and to elucidate potential underlying immunological mechanism. The role of the adjuvant in particular warrants further research before drawing

    Otitis media (OM) is a highly prevalent paediatric disease with both bacterial and viral triggers of infection. This study has investigated how combinations of bacteria associated with nasal colonisation and the occurrence and absence of viral infection (Sendai virus) induce OM in a mouse nasal colonisation model. The respiratory virus significantly contributed to bacterial OM for all bacterial combinations (pbacteria inoculated groups even in the absence of viable bacterial recovery. Phagocytic cells were recruited rapidly to the ear following nasal inoculation but over time their numbers did not correlate with persistence of bacterial infection. The study has shown that the composition of bacteria in the nasal cavity and respiratory viral infection significantly affected the OM incidence rate, duration of infection and bacterial load (severity).

    Full Text Available This study examined the spatial distribution of childhood community-acquired pneumonia detected through prospective surveillance in Goiânia, Brazil. Three spatial analysis techniques were applied to detect intra-urban geographic aggregation of pneumonia cases: Kernel method, nearest neighbor hierarchical technique, and spatial scan statistic. A total of 724 pneumonia cases confirmed by chest radiography were identified from May 2000 to August 2001. All cases were geocoded on a digital map. The annual pneumonia risk rate was estimated at 566 cases/100,000 children. Analysis using traditional descriptive epidemiology showed a mosaic distribution of pneumonia rates, while GIS methodologies showed a non-random pattern with hot spots of pneumonia. Cluster analysis by spatial scan statistic identified two high-risk areas for pneumonia occurrence, including one most likely cluster (RR = 2.1; p Este estudo avaliou três técnicas de análise espacial para detectar aglomerados intra-urbanos de casos de pneumonias na infância: método de Kernel, técnica de hierarquia de vizinhos próximos e estatística espacial scan.

Factors investigated included recognition of danger signs of CAP, health care decision making, self-medication, treatment and referral by local practitioners, and perceptions about quality of care.Qualitative research employing case studies (CS of care-seeking, key informant interviews (KII, semi-structured interviews (SSI and focus group discussions (FGD with both video presentations of CAP signs, and case scenarios. Interviews and FGDs were conducted with parents of under-five children who had suffered CAP, community health workers (CHW, and rural medical practitioners (RMP.From September 2013 to January 2014, 30 CS, 43 KIIs, 42 SSIs, and 42 FGDs were conducted. Recognition of danger signs of CAP among caregivers was poor. Fast breathing, an early sign of CAP, was not commonly recognized. Chest in-drawing was recognized as a sign of serious illness, but not commonly monitored by removing a child's clothing. Most cases of mild to moderate CAP were brought to RMP, and more severe cases taken to private clinics in towns. Mothers consulted local RMP directly, but decisions to visit doctors outside the village required consultation with husband or mother-in-law. By the time most cases reached a public tertiary-care hospital, children had been ill for a week and treated by 2-3 providers. Quality of care at government facilities was deemed poor by caregivers.To reduce CAP-associated mortality, recognition of its danger signs and the consequences of treatment delay needed to be better recognized by caregivers, and confidence in government facilities increased. The involvement of RMP in community based CAP programs needs to be investigated further given their widespread

    Nursing home-acquired pneumonia (NHAP) was first described in 1978. Since then there has been much written regarding NHAP and its management despite the lack of well-designed studies in this patient population. The most characteristic features of patients with NHAP are the atypical presentation, which may lead to delay in diagnosis and therapy. The microbial etiology of pneumonia encompasses a wide spectrum that spans microbes recovered from patients with community-acquired pneumonia to organisms considered specific only to nosocomial settings. Decision to transfer a nursing home patient to an acute care facility depends on a host of factors, which include the level of staffing available at the nursing home, patients' advance directives, and complexity of treatment. The presence of risk factors for multidrug-resistant pathogens dictates approach to therapy. Prevention remains the cornerstone of reducing the incidence of disease. Despite the advance in medical services, mortality from NHAP remains high.

    Although pneumonia is associated with an increased risk of venous thromboembolism, patients with pulmonary embolism and concomitant pneumonia are uncommon. The aim of the present study was to investigate the clinical features of pulmonary embolism with coexisting pneumonia. We retrospectively compared clinical, radiologic and laboratory parameters between patients with pulmonary embolism and concomitant pneumonia (pneumonia group) and those with unprovoked pulmonary embolism (unprovoked group), and then between the pneumonia group and those with pulmonary infarction (infarction group). Of 794 patients with pulmonary embolism, 36 (5%) had coexisting pneumonia and six (1%) had no provoking factor other than pneumonia. Stroke was significantly more common in the pneumonia group, than either the unprovoked group or the infarction group. In the pneumonia group, fever was significantly more common and serum C-reactive protein levels were significantly higher. By contrast, central pulmonary embolism and right ventricular dilation on computed tomography were significantly less frequent in the pneumonia group. In addition, an adverse outcome due to pulmonary embolism was less common in the pneumonia group than in either of the other two groups. The coexistence of pulmonary embolism and pneumonia is rarely encountered in clinical practice, especially without the presence of other factors that could provoke venous thromboembolism and is commonly associated with stroke. It is characterized by lower incidences of central pulmonary embolism and right ventricular dilation and by a lower rate of adverse outcomes due to pulmonary embolism itself.

    Full Text Available Introduction: Pneumonia is one of the most common infections during childhood. In children with recurrent bacterial pneumonia complete evaluation for underlying factors is necessary. The most common underlying diseases include: antibody deficiencies , cystic fibrosis , tracheoesophageal fistula and increased pulmonary blood flow. Vascular ring and its pressure effect is a less common cause of stridor and recurrent pneumonia. Congenital abnormalities in aortic arch and main branches which form vascular ring around esophagus and trachea with variable pressure effect cause respiratory symptoms such as stridor , wheezing and recurrent pneumoniaCase Report: A 2 year old boy was admitted in our hospital with respiratory distress and cough . Chest x-Ray demonstrated right lobar pneumonia. He had history of stridor and wheezing from neonatal period and hospitalization due to pneumonia for four times. The patient received appropriate antibiotics. Despite fever and respiratory distress improvement, wheezing continued. Review of his medical documents showed fixed pressure effect on posterior aspect of esophagus in barium swallow. In CT angiography we confirmed double aortic arch.Conclusion: Double aortic arch is one of the causes of persistant respiratory symptom and recurrent pneumonia in children for which fluoroscopic barium swallow is the first non-invasive diagnostic method.(Sci J Hamadan Univ Med Sci 2012;19(1:70-74

    Full Text Available Abstract Background Although the incidence of serious morbidity with childhood pneumonia has decreased over time, empyema as a complication of community-acquired pneumonia continues to be an important clinical problem. We reviewed the epidemiology and clinical management of empyema at 8 pediatric hospitals in a period before the widespread implementation of universal infant heptavalent pneumococcal vaccine programs in Canada. Methods Health records for children Results 251 children met inclusion criteria; 51.4% were male. Most children were previously healthy and those ≤ 5 years of age comprised 57% of the cases. The median length of hospitalization was 9 days. Admissions occurred in all months but peaked in winter. Oxygen supplementation was required in 77% of children, 75% had chest tube placement and 33% were admitted to an intensive care unit. While similarity in use of pain medication, antipyretics and antimicrobial use was observed, a wide variation in number of chest radiographs and invasive procedures (thoracentesis, placement of chest tubes was observed between centers. The most common organism found in normally sterile samples (blood, pleural fluid, lung biopsy was Streptococcus pneumoniae. Conclusion Empyema occurs most commonly in children under five years and is associated with considerable morbidity. Variation in management by center was observed. Enhanced surveillance using molecular methods could improve diagnosis and public health planning, particularly with regard to the relationship between immunization programs and the epidemiology of empyema associated with community-acquired pneumonia in children.

    Community-acquired pneumonia (CAP) is a leading cause of adult morbidity and mortality worldwide despite decades of effective antibiotics and vaccination initiatives. There have been no recent significant improvements in outcomes, including 30-day mortality. The bacterium Streptococcus pneumoniae is the most prevalent causative pathogen in CAP, being found in up to half of cases. In September 2006 a childhood pneumococcal vaccine (PCV-7) was introduced, leading to reductions in vaccine-type (...

    Incidence and mortality rates of infections caused by Streptococcus pneumoniae (pneumococcus) are high worldwide and in Hungary among paediatric as well as adult populations. Pneumococci account for 35-40% of community acquired adult pneumonias requiring hospitalization, while 25-30% of Streptococcus pneumoniae pneumonias are accompanied by bacteraemia. 5-7% of all infections are fatal but this rate is exponentially higher in high risk patients and elderly people. Mortality could reach 20% among patients with severe invasive pneumococcal infections. Complications may develop despite administration of adequate antibiotics. The authors summarize the epidemiology of pneumococcal infections, pathogenesis of non-invasive and invasive disease and present basic clinical aspects through demonstration of four cases. Early risk stratification, sampling of hemocultures, administration of antibiotics and wider application of active immunization could reduce the mortality of invasive disease. Anti-pneumococcal vaccination is advisable for adults of ≥50 years and high risk patients of ≥18 years who are susceptible to pneumococcal disease.

    Experimental pneumonia was produced in calves by the endobronchial inoculation of pneumonic lung homogenates. Irradiated homogenates produced minimal pneumonia. Ampicillin treatment of the homogenates and the experimental calves reduced the extent of pneumonia. Treatment with tylosin tartrate prevented experimental pneumonia. These results suggest that the total pneumonia was due to organisms susceptible to tylosin tartrate and that the residual pneumonia remaining after ampicillin treatment was due to organisms susceptible to tylosin tartrate but not to ampicillin. Of the organisms isolated from the lungs, the ones in this latter category most likely to be responsible are Mycoplasma dispar and ureaplasmas (T-mycoplasmas).

    One of the major health consequences of the Chernobyl Nuclear Power Plant accident in 1986 was a dramatic increase in incidence of thyroid cancer among those who were aged less than 18 years at the time of the accident. This increase has been directly linked in several analytic epidemiological studies to iodine-131 (131I) thyroid doses received from the accident. However, there remains limited understanding of factors that modify the 131I-related risk. Focusing on post-Chernobyl pediatric thyroid cancer in Belarus, we reviewed evidence of the effects of radiation, thyroid screening, and iodine deficiency on regional differences in incidence rates of thyroid cancer. We also reviewed current evidence on content of nitrate in groundwater and thyroid cancer risk drawing attention to high levels of nitrates in open well water in several contaminated regions of Belarus, i.e. Gomel and Brest, related to the usage of nitrogen fertilizers. In this hypothesis generating study, based on ecological data and biological plausibility, we suggest that nitrate pollution may modify the radiation-related risk of thyroid cancer contributing to regional differences in rates of pediatric thyroid cancer in Belarus. Analytic epidemiological studies designed to evaluate joint effect of nitrate content in groundwater and radiation present a promising avenue of research and may provide useful insights into etiology of thyroid cancer.

    áticos en niños menores de 15 años, de 1982 a 1991, y de 1996 a 1999.Objective. To evaluate the incidence trends of hepatic tumors among children living in Mexico City. Material and Methods. A cross-sectional hospital survey was conducted to yield two databases. The first database contains the registry of all the cases of hepatic tumors occurring during the period 1982-1991, in public hospitals of Mexico City. The second database contains all hepatic tumor cases found between 1996 and 1999 in Hospital de Pediatría del Centro Médico Nacional "Siglo XXI" and in Hospital General del Centro Médico La Raza, both hospitals pertaining to Instituto Mexicano del Seguro Social (Mexican Institute of Social Security. The average annual incidence rates (AAIR were calculated for each type of hepatic tumor. The rates were standardized with the direct method, using as standard the world population under 15 years of age. The trends were evaluated with the annual incidence rates and the average rate of change assuming a Poisson distribution. Results. The AAIR for hepatoblastoma during the period 1982-1991 was three times higher for men than for women, with a value of 0.6 x10(6. The group of 1-4 years of age was the most affected. For hepatocarcinomas the AAIR was two-fold for women (0.14 as compared to men. Between 1996-1999 the AAIR for hepatoblastoma was 5.11 in women and 1.85 in men. The age group with the highest rate was women under one year of age. The AAIR for hepatocarcinoma was 0.64 for males and 1.23 for females. The most affected age group was males aged 10 to 14 years. No significant upward or downward trend was found in the incidence of hepatoblastomas. A non-significant change rate of 10% was found for hepatocarcinoma. Conclusions. No significant trends were observed in the incidence of hepatic tumors in children of Mexico City aged under 15 years, during the periods 1982-1991 and 1996-1999.

    Hixson, S; Sole, M L; King, T

    1998-02-01

    Critically ill patients who require mechanical ventilation are at high risk for development of pneumonia during the course of treatment. Ventilator-associated pneumonia leads to higher rates of mortality and morbidity, increased length of hospital stay, and higher hospital costs. The intubation that is necessary for mechanical ventilation impairs the patient's normal defense mechanisms for fighting infection. Impaired defenses, along with such risk factors as age of the patient, equipment used, and failure of the staff to wash hands increase the likelihood of colonization of the lower airways. Colonization and subsequent pneumonia commonly occurs from microaspiration of secretions from the oropharynx and gastrointestinal tract. In this article, the mechanism of microaspiration, diagnosis of ventilator-associated pneumonia, and nursing strategies to reduce the incidence of pneumonia are described.

    This paper critically reviews the association of infection by Chlamydophila pneumoniae (C. pneumoniae) and Alzheimer's disease (AD). The aging population has increased interest in finding the cause of AD, but studies have yielded contradictory results that are likely due to varying diagnostic tools and different uses of diagnostic tests. Knowledge of AD's characteristics, risk factors, and hypothesized etiologies has expanded since Alois Alzheimer's initial description of AD. Epidemiologic and projection studies provide incidence estimates of AD through a two-stage method: (1) primary diagnosis of dementia by cognitive testing such as Mini-Mental State Examination (MMSE), and (2) clinical diagnosis of AD through criteria such as National Institute of Neurological and Communicative Diseases and Stroke/Alzheimer's Disease and Related Disorders Association (NINCDS-ADRDA). Cross-sectional studies yield prevalence estimates of infection by C. pneumoniae by detecting immunoglobulins through laboratory tests such as microimmunofluorescence (MIF). Studies examining the association of C. pneumoniae and AD are limited, but brain autopsy provides information about presence, proximity to areas associated with AD, and bacterial load. Standardization of diagnostic techniques would allow for better comparability of studies, but uncertainty about the best method of diagnosis of infection by C. pneumoniae and AD may call for revised or novel diagnostic tools.

    More than three-quarters of deaths related to major burns are a consequence of infection, which is frequently ventilator associated pneumonia (VAP). A retrospective study was performed, over a five-year period, of ventilated children with major burns. 92 patients were included in the study; their mean age was 3.5 years and their mean total body surface area burn was 30%. 62% of the patients sustained flame burns, and 31% scalds. The mean ICU stay was 10.6 days (range 2-61 days) and the mean ventilation time was 8.4 days (range 2-45 days). There were 59 documented episodes of pneumonia in 52 patients with a rate of 30 infections per 1000 ventilator days. Length of ventilation and the presence of inhalational injury correlate with the incidence of VAP. 17.4% of the patients died (n=16); half of these deaths may be attributed directly to pneumonia. Streptococcus pneumonia, Pseudomonas aeruginosa, Acinetobacter baumanii and Staphylococcus aureus were the most prominent aetiological organisms. Broncho-alveolar lavage was found to be more specific and sensitive at identifying the organism than other methods. This study highlights the importance of implementing strictly enforced strategies for the prevention, detection and management of pneumonia in the presence of major burns.

    Pneumonia's burden is still important worldwide not only because of its high incidence and mortality, but also for the elevated costs related to it. Despite the concerted efforts to reduce the incidence of sepsis-related complications, they continue to represent a major human and economic burden. The cornerstone of sepsis management is early appropriate empiric broad spectrum antibiotics, resuscitation, and source control. The association between inappropriate use of antibiotics and increased mortality is the rationale for the use of empiric antibiotic combination therapy in critically ill patients. The aim of this manuscript was to discuss recent literature regarding the management of severe pneumonia, both community-acquired and hospital-acquired/ventilator-associated, in critically ill patients. Use of combination therapy is warranted in severe infections with shock; considerations should be made on the importance of optimal antibiotic administration and adverse reactions, thus providing guidance for a rational use of antibiotics.

    The ten-pneumococcal conjugate vaccine (PCV10) was introduced into the national immunization program for childhood vaccination schedules by the Brazilian Health Public Service in March 2010. The aim of this study was to compare Streptococcus pneumoniae serotype distribution, antibiotic resistance patterns, and potential coverage before (January 2006-June 2010) and after (July 2010-September 2012) PCV10 introduction. The incidence of invasive pneumococcal disease (IPD), patient demographics, and disease characteristics were recorded. This study was conducted at the University Hospital of Sao Paulo University in Brazil from January 2006 to September 2012. Serotyping was performed using multiplex PCR typing, and antimicrobial sensitivity by Clinical and Laboratory Standards Institute (CLSI). A total of 259 S. pneumoniae strains were isolated from patients with IPD. The ages of the patients ranged from 3 months to 95 years old. The strains were isolated from cerebrospinal fluid, pleural fluid, and blood. The incidence of IPD among patients at HU-USP changed after the introduction of PCV10. The overall incidence of IPD was 3.42 cases per 1000 admissions in the vaccine pre- implementation period and of 2.99 cases per 1000 admissions in the vaccine post-implementation period. The incidence of IPD among children<2 y.o. attended at HU-USP changed significantly after the introduction of PCV10, from 20.30 to 3.97 of incidence. The incidence of PCV10- serotypes decrease from 16.47 to 0.44 in the same age, before and after PC10 implementation, respectively. Moreover, it was possible to realize the sensitivity to penicillin among isolates increased significantly in the post-vaccine period. Data from this study suggest that PCV10 contributed to decrease with PID rate among children less than 2 y.o. The resistance rate among pneumococcal isolates also could be observed since serotypes with greater resistance to beta lactam antibiotics were not easily isolated after vaccination.

    Although immunization has decreased the incidence of bacterial pneumonia in vaccinated children, pneumonia remains common in healthy children. Symptoms of bacterial pneumonia frequently overlap those present with viral infections or reactive airway disease. Optimally, the diagnosis of bacterial pneumonia should be supported by a chest radiograph before starting antimicrobials. Factors such as age, vital signs and other measures of illness severity are critical when deciding whether to admit a patient to hospital. Because Streptococcus pneumoniae continues to be the most common cause of bacterial pneumonia in children, prescribing amoxicillin or ampicillin for seven to 10 days remains the mainstay of empirical therapy for nonsevere pneumonia. If improvement does not occur, consideration should be given to searching for complications (empyema or lung abscess). Routine chest radiographs at the end of therapy are not recommended unless clinically indicated. PMID:26744558

    Bronchiolitis is an acute lower respiratory tract infection in early childhood caused mainly by different viruses. Etiology of bronchiolitis have been studied in different environments and populations. Respiratory syncytial virus (RSV), human Metapneumovirus (hMPV), human Bocavirus (hBoV), human Rhinoviruses (hRV) have consistently been shown to predominate. Few studies however have attempted to determine whether other pathogens, particularly Mycoplasma Pneumoniae (MP) and Chlamydophila pneumoniae (CP), are associated with bronchiolitis in children under 2 years of age. The aim of this study was to determine the prevalence and clinical features of MP and CP in children under the age of 2 years presenting to the Iashvili Central Children Hospital in Tbilisi with various severities and clinical manifestations of bronchiolitis. Acute and convalescent serum samples were tested by ELISA for IgM and IgG antibodies to RSV, CP and MP.37 children under two years of age were studied. In 19 patients out of 37 (51.35%) etiological diagnosis were established and in 18 patients (48.65%) no pathogens were found. 11 patients (29.72%) had either CP or MP and 8 patients (21.62%) had RSV. Children infected with CP and MP had less severe bronchiolitis than those infected with RSV. Co-infection was not associated with disease severity. There were no statistically significant differences between groups with respect to length of hospital stay. Our study underlines the importance of atypical bacterial pathogens in acute bronchiolitis in children under 2 years and highlights the complex epidemiology and clinical features of these pathogens in this age group.

    Bacterial pericarditis in children has become a rare entity in the modern antibiotic era. The most common pathogen is Staphylococcus aureus, being Streptococcus pneumoniae an exceptional cause. We present 2 children, who were diagnosed of pneumonia complicated with a pleural effusion that developed a purulent pericarditis with signs of cardiac tamponade. One of them had received 4 doses of the 7-valent conjugated pneumococcal vaccine. Systemic antibiotics and pericardial and pleural drainages were used. Pneumococcal antigens were positive in pleural and pericardial fluids in both cases, and S. pneumoniae was isolated from pleural effusion in one of them. Both children fully recovered, and none of them developed constrictive pericarditis, although 1 case presented a transient secondary left ventricular dysfunction. Routine immunization with 10- and 13-valent vaccines including a wider range of serotypes should further decrease the already low incidence.

    Although there are high survival rates for children with acute lymphoblastic leukaemia, their outcome is often counterbalanced by the burden of toxic effects. This is because reported frequencies vary widely across studies, partly because of diverse definitions of toxic effects. Using the Delphi...... method, 15 international childhood acute lymphoblastic leukaemia study groups assessed acute lymphoblastic leukaemia protocols to address toxic effects that were to be considered by the Ponte di Legno working group. 14 acute toxic effects (hypersensitivity to asparaginase, hyperlipidaemia, osteonecrosis......, thromboembolism, and Pneumocystis jirovecii pneumonia) that are serious but too rare to be addressed comprehensively within any single group, or are deemed to need consensus definitions for reliable incidence comparisons, were selected for assessment.

    Seasonal variations in the incidence of pneumonia and influenza are associated with nosocomial Clostridium difficile infection (CDI) incidence, but the reasons why remain unclear. Our objective was to consider the impact of pneumonia and influenza timing and severity on CDI incidence. We conducted a retrospective cohort study using the US National Hospital Discharge Survey sample. Hospitalized patients with a diagnosis of CDI or pneumonia and influenza between 1993 and 2008 were identified from the National Hospital Discharge Survey data set. Poisson regression models of monthly CDI incidence were used to measure 1) the time lag between the annual pneumonia and influenza prevalence peak and the annual CDI incidence peak and 2) the lagged effect of pneumonia and influenza prevalence on CDI incidence. CDI was identified in 18,465 discharges (8.52 per 1,000 discharges). Peak pneumonia prevalence preceded peak CDI incidence by 9.14 weeks (95% confidence interval: 4.61, 13.67). A 1% increase in pneumonia prevalence was associated with a cumulative effect of 11.3% over a 6-month lag period (relative risk = 1.113, 95% confidence interval: 1.073, 1.153). Future research could seek to understand which mediating pathways, including changes in broad-spectrum antibiotic prescribing and hospital crowding, are most responsible for the associated changes in incidence.

  14. Measuring coverage in MNCH: challenges in monitoring the proportion of young children with pneumonia who receive antibiotic treatment.

    Directory of Open Access Journals (Sweden)

    Harry Campbell

    Full Text Available Pneumonia remains a major cause of child death globally, and improving antibiotic treatment rates is a key control strategy. Progress in improving the global coverage of antibiotic treatment is monitored through large household surveys such as the Demographic and Health Surveys (DHS and the Multiple Indicator Cluster Surveys (MICS, which estimate antibiotic treatment rates of pneumonia based on two-week recall of pneumonia by caregivers. However, these survey tools identify children with reported symptoms of pneumonia, and because the prevalence of pneumonia over a two-week period in community settings is low, the majority of these children do not have true pneumonia and so do not provide an accurate denominator of pneumonia cases for monitoring antibiotic treatment rates. In this review, we show that the performance of survey tools could be improved by increasing the survey recall period or by improving either overall discriminative power or specificity. However, even at a test specificity of 95% (and a test sensitivity of 80%, the proportion of children with reported symptoms of pneumonia who truly have pneumonia is only 22% (the positive predictive value of the survey tool. Thus, although DHS and MICS survey data on rates of care seeking for children with reported symptoms of pneumonia and other childhood illnesses remain valid and important, DHS and MICS data are not able to give valid estimates of antibiotic treatment rates in children with pneumonia.

    AP is a major cause of morbidity and mortality in elderly patients, especially frail elderly patients. The aim of this article is to review effect of oral care, including oral hygiene and improvement of oral function, on the prevention of AP among elderly people in hospitals and nursing homes. There is now a substantial body of work studying the effect of oral care on the prevention of respiratory diseases. Oral hygiene, consisting of oral decontamination and mechanical cleaning by dental professionals, has resulted in significant clinical effects (decreased incidence of pneumonia and decreased mortality from respiratory diseases) in clinical randomized trials. Moreover, studies examining oral colonization by pneumonia pathogens have shown the effect of oral hygiene on eliminating these pathogens. In addition, swallowing training has been shown to improve the movement and function of swallowing-related muscles, also resulting in decreased incidence of pneumonia. These findings support the contention that oral care is effective in the prevention of AP.

    Low zinc status may be a risk factor for pneumonia in the elderly. This special article reviews the magnitude of the problem of pneumonia (its prevalence, morbidity, and mortality) in the elderly, pneumonia's etiology, and the dysregulation of the immune system associated with increasing age. In addition, recent evidence from the literature is presented demonstrating that low zinc status (commonly reported in the elderly) impairs immune function, decreases resistance to pathogens, and is associated with increased incidence and duration of pneumonia, increased use and duration of antimicrobial treatment, and increased overall mortality in the elderly. Inadequate stores of zinc might, therefore, be a risk factor for pneumonia in the elderly. Randomized, double-blind, controlled studies are needed to determine the efficacy of zinc supplementation as a potential low-cost intervention to reduce morbidity and mortality due to pneumonia in this vulnerable population.

Methods Twenty-six patients admitted to the intensive care unit, West China Hospital, Sichuan University, from June to December in 2007, with confirmed VAP were randomized to two groups: conventional group (14 cases) and carbapenem restriction group (12 cases). All sputum samples were collected throughout the trial. The correlation between the incidence of MDR Acinetobacter baumannii and the consumption of carbapenem was analyzed. Results The incidence of MDR Acinetobacter baumannii (10.7%, 7/65) and consumption of carbapenem (61 g) in carbapenem restriction group were significantly lower than conventional group (17.8%, 13/73, 188 g, both P <0.05). The result implied that the decreased incidence of MDR Acinetobacter baumannii was attributable to the reduction of carbapenem consumption. Conclusion Carbapenem constraint could reduce the incidence of MDR Acinetobacter baumannii in VAP.%目的 分析重症监护病房(ICU)内碳青霉烯抗生素的处方量与呼吸机相关性肺炎(VAP)多药耐药(MDR)鲍曼不动杆菌发生率的关系.方法 选择2007年6-12月四川大学华西医院ICU收治的行机械通气的VAP患者26例,随机分为采用碳青霉烯抗生素"处方限制策略"组(限制组,12例)和不加限制组(常规组,14例),收集两组患者治疗期的痰标本,分析MDR细菌的分布及与同期碳青霉烯抗生素处方量的相关性.结果 限制组碳青霉烯抗生素处方量以及MDR鲍曼不动杆菌的发生率均较常规组显著降低,差异有统计学意义(处方量:61 g比188 g,发生率:10.7%(7/65)比17.8%(13/73),P均<0.05].提示MDR鲍曼不动杆菌发生率的降低归因于碳青霉烯处方量的减少.结论 采取碳青霉烯"处方限制策略"可以减少VAP MDR鲍曼不动杆菌的发生率.

    Interactions arising from sequential viral and bacterial infections play important roles in the epidemiological outcome of many respiratory pathogens. Influenza virus has been implicated in the pathogenesis of several respiratory bacterial pathogens commonly associated with pneumonia. Though clinical evidence supporting this interaction is unambiguous, its population-level effects-magnitude, epidemiological impact and variation during pandemic and seasonal outbreaks-remain unclear. To address these unknowns, we used longitudinal influenza and pneumonia incidence data, at different spatial resolutions and across different epidemiological periods, to infer the nature, timing and the intensity of influenza-pneumonia interaction. We used a mechanistic transmission model within a likelihood-based inference framework to carry out formal hypothesis testing. Irrespective of the source of data examined, we found that influenza infection increases the risk of pneumonia by ~100-fold. We found no support for enhanced transmission or severity impact of the interaction. For model-validation, we challenged our fitted model to make out-of-sample pneumonia predictions during pandemic and non-pandemic periods. The consistency in our inference tests carried out on several distinct datasets, and the predictive skill of our model increase confidence in our overall conclusion that influenza infection substantially enhances the risk of pneumonia, though only for a short period.

    Full Text Available The increasing burden of pneumonia in adults is an emerging health issue in the era of global population aging. This study was conducted to elucidate the burden of community-onset pneumonia (COP and its etiologic fractions in Japan, the world's most aged society.A multicenter prospective surveillance for COP was conducted from September 2011 to January 2013 in Japan. All pneumonia patients aged ≥ 15 years, including those with community-acquired pneumonia (CAP and health care-associated pneumonia (HCAP, were enrolled at four community hospitals on four major islands. The COP burden was estimated based on the surveillance data and national statistics.A total of 1,772 COP episodes out of 932,080 hospital visits were enrolled during the surveillance. The estimated overall incidence rates of adult COP, hospitalization, and in-hospital death were 16.9 (95% confidence interval, 13.6 to 20.9, 5.3 (4.5 to 6.2, and 0.7 (0.6 to 0.8 per 1,000 person-years (PY, respectively. The incidence rates sharply increased with age; the incidence in people aged ≥ 85 years was 10-fold higher than that in people aged 15-64 years. The estimated annual number of adult COP cases in the entire Japanese population was 1,880,000, and 69.4% were aged ≥ 65 years. Aspiration-associated pneumonia (630,000 was the leading etiologic category, followed by Streptococcus pneumoniae-associated pneumonia (530,000, Haemophilus influenzae-associated pneumonia (420,000, and respiratory virus-associated pneumonia (420,000, including influenza-associated pneumonia (30,000.A substantial portion of the COP burden occurs among elderly members of the Japanese adult population. In addition to the introduction of effective vaccines for S. pneumoniae and influenza, multidimensional approaches are needed to reduce the pneumonia burden in an aging society.

    Full Text Available It is not known whether rainfall increases the risk of sporadic cases of Legionella pneumonia. We sought to test this hypothesis in a prospective observational cohort study of non-immunosuppressed adults hospitalized for community-acquired pneumonia (1995-2011. Cases with Legionella pneumonia were compared with those with non-Legionella pneumonia. Using daily rainfall data obtained from the regional meteorological service we examined patterns of rainfall over the days prior to admission in each study group. Of 4168 patients, 231 (5.5% had Legionella pneumonia. The diagnosis was based on one or more of the following: sputum (41 cases, antigenuria (206 and serology (98. Daily rainfall average was 0.556 liters/m(2 in the Legionella pneumonia group vs. 0.328 liters/m(2 for non-Legionella pneumonia cases (p = 0.04. A ROC curve was plotted to compare the incidence of Legionella pneumonia and the weighted median rainfall. The cut-off point was 0.42 (AUC 0.54. Patients who were admitted to hospital with a prior weighted median rainfall higher than 0.42 were more likely to have Legionella pneumonia (OR 1.35; 95% CI 1.02-1.78; p = .03. Spearman Rho correlations revealed a relationship between Legionella pneumonia and rainfall average during each two-week reporting period (0.14; p = 0.003. No relationship was found between rainfall average and non-Legionella pneumonia cases (-0.06; p = 0.24. As a conclusion, rainfall is a significant risk factor for sporadic Legionella pneumonia. Physicians should carefully consider Legionella pneumonia when selecting diagnostic tests and antimicrobial therapy for patients presenting with CAP after periods of rainfall.

    Pneumonias in elderly are frequent and severe. They require an accurate assessment following clinical, biological and radiological steps. Each of them can contribute to give answers to the following questions: does this patient need emergency hospitalisation? Is the infection really bacterial and pulmonary? Should antibiotics be started? Which others treatments should be associated for the infection itself and for comorbid conditions? Concerning prevention, every effort must be done to decrease the incidence of these infections, especially vaccination. Pulmonary infections in nursing home need specific attention: cumulation of bad prognosis factors, risk of epidemic propagation, and vaccination of all people caring patients when required.

    2005-01-01

    Full Text Available Background/Aim. Pneumonia is the most frequent complication in acute psychotropic drugs poisoning, which results in substantial morbidity and mortality, but which also increases the costs of treatment. Risk factors for pneumonia are numerous: age, sex, place of the appearance of pneumonia, severity of underlying disease, airway instrumentation (intubation, reintubation, etc. The incidence of pneumonia varies in poisoning caused by the various groups of drugs. The aim of this study was to determine the incidence and risk factors for pneumonia in the patients with acute psychotropic drugs poisoning. Methods. A group of 782 patients, out of which 614 (78.5% with psychotropic and 168 (21.5% nonpsychotropic drug poisoning were analyzed prospectively during a two-year period. The diagnosis of pneumonia was made according to: clinical presentation, new and persistent pulmonary infiltrates on chest radiography, positive nonspecific parameters of inflammation, and the microbiological confirmation of causative microorganisms. To analyze predisposing risk factors for pneumonia, the following variables were recorded: sex, age, underlying diseases, endotracheal intubation, coma, severity of poisoning with different drugs, histamine H2 blockers, corticosteroids, mechanical ventilation, central venous catheter. The univariate analysis for pneumonia risk factors in all patients, and for each group separately was done. The multivariate analysis was performed using the logistic regression technique. Results. Pneumonia was found in 94 (12.02% of the patients, 86 of which (91.5% in psychotropic and 8 (8.5% in nonpsychotropic drug poisoning. In the psychotropic drug group, pneumonia was the most frequent in antidepressant (47%, and the rarest in benzodiazepine poisoning (3.8%. A statistically significant incidence of pneumonia was found in the patients with acute antidpressant poisoning (p < 0.001. Univariate analysis showed statistical significance for the

    Pneumonia is the most common complication observed in patients with severe injuries. Although the average age of injured patients is 47 years, existing studies of the effect of injury on the susceptibility to infectious complications have focused on young animals, equivalent to a late adolescent human. We hypothesized that mature adult animals are more susceptible to infection after injury than younger counterparts. To test this hypothesis, we challenged 6 to 8-month-old mature mice to a polytrauma injury followed by Pseudomonas aeruginosa pneumonia and compared them to young (8-10-week-old) animals. We demonstrate that polytrauma injury increases mortality from pneumonia in mature animals (sham-pneumonia 21% vs. polytrauma-pneumonia 62%) but not younger counterparts. After polytrauma, pneumonia in mature mice is associated with higher bacterial burden in lung, increased incidence of bacteremia, and elevated levels of bacteria in the blood, demonstrating that injury decreases the ability to control the infectious challenge. We further find that polytrauma did not induce elevations in circulating cytokine levels (TNF-alpha, IL-6, KC, and IL-10) 24  h after injury. However, mature mice subjected to polytrauma demonstrated an exaggerated circulating inflammatory cytokine response to subsequent Pseudomonas pneumonia. Additionally, whereas prior injury increases LPS-stimulated IL-6 production by peripheral blood leukocytes from young (8-10-week-old) mice, injury does not prime IL-6 production by cell from mature adult mice. We conclude that in mature mice polytrauma results in increased susceptibility to Pseudomonas pneumonia while priming an exaggerated but ineffective inflammatory response.

    Full Text Available The aim of this study was to determine the relationship between infection with “persistent” agents of children and the possibility of the development of inflammatory diseases of the respiratory tract such as community-acquired pneumonia and acute bronchitis on the basis of risk management concepts.Materials and methods. 701 children in age from 15 days to 16 years were examined in Nizhny Novgorod and the Nizhny Novgorod region with clinically and radiologically confirmed diagnosis: community-acquired pneumonia, acute bronchitis. This study was performed in the period from 2005 to 2014. The control group consisted of 127 healthy children of different ages. The detection of M. pneumoniae, Сytomegalovirus, Herpes simplex I/II C. pneumoniae was performed by PCR. The concept of risk determination was based on the determination of the absolute risk in the exposed and the no exposed groups, attributable risk, relative risk, the population attributable risk, as well as determining the standard errors for each type of risk and confidence interval.Results. Attributable risk, relative risk, population-attributable risk are statistically significant figures. Attributable risk of development of community-acquired pneumonia was 29,26%; 27,37%; 25,70%; 20,21% for the M. pneumoniae, C. pneumoniae, CMV, HSV I / II respectively. The relative risk was 1,43 for the M. pneumoniae; 1,38 – for C. pneumoniae and CMV; 1,28- for HSV I / II. The presence of persistent pathogens is resulting in increased incidence of communityacquired pneumonia throughout the population (population attributable risk: 4,75% for M. pneumoniae, 0,23% for C. pneumoniae, 5,59% for the CMV and 1,08% for the HSV I/II. Similar calculations were performed for patients with acute bronchitis. The statistical analysis allowed to exclude C. pneumoniae and HSV I / II of the risk factors for communityacquired pneumonia and acute bronchitis.Conclusion. The findings suggest the influence of M

    Polymicrobial aetiology in community-acquired pneumonia (CAP) is more common than previously recognized. This growing new entity can influence inflammation, host immunity and disease outcomes in CAP patients. However, the true incidence is complicated to determine and probably underestimated due mainly to many cases going undetected, particularly in the outpatient setting, as the diagnostic yield is restricted by the sensitivity of currently available microbiologic tests and the ability to get certain types of clinical specimens. The observed rate of polymicrobial cases may also lead to new antibiotic therapy considerations. In this review, we discuss the pathogenesis, microbial interactions in pneumonia, epidemiology, biomarkers and antibiotic therapy for polymicrobial CAP.

    Pulmonary tuberculosis (PTb) and pneumonia are diseases that may exist concomitantly. Population study investigating the subsequent pneumonia development in PTb patients is limited. This study compares the risk of pneumonia between cohorts with and without PTb.We used the claims data of the Taiwan National Health Insurance to identify a cohort with PTb (N = 3417) newly diagnosed in 2000-2006 without pneumonia history, and a randomly selected comparison cohort (N = 6834) free of PTb and pneumonia, frequency matched by propensity score. Incidence rates and hazard ratios of pneumonia were calculated by sex, age, and comorbidity starting in the 7th month after the cohorts being established until the end of 2011.We found the incidence of pneumonia to be 1.9-fold higher in the PTb cohort than in the PTb free cohort (51.6 vs 27.0 per 1000 person-years). The PTb cohort had a Cox method estimated adjusted hazard ratio of 2.14 (95% confidence interval = 1.96-2.32). We also found that the risk was greater for men than for women, but lower for young adults aged 20-39 years. Comorbidity interacted with PTb by aggravating the pneumonia risk, particularly for those with asthma. For PTb patients comorbid with asthma, the pneumonia incidence was 2.5-fold higher than for PTb patients free of comorbidities (75.9 vs 29.3 per 1000 person-years).Our results display that PTb patients have an elevated risk of developing pneumonia. Adequate follow-up should be provided to the PTb patients, especially those with comorbidity.

    Full Text Available BACKGROUND: Few comprehensive data exist on disease incidence for specific etiologies of acute respiratory illness (ARI in older children and adults in Africa. METHODOLOGY/PRINCIPAL FINDINGS: From March 1, 2007, to February 28, 2010, among a surveillance population of 21,420 persons >5 years old in rural western Kenya, we collected blood for culture and malaria smears, nasopharyngeal and oropharyngeal swabs for quantitative real-time PCR for ten viruses and three atypical bacteria, and urine for pneumococcal antigen testing on outpatients and inpatients meeting a ARI case definition (cough or difficulty breathing or chest pain and temperature >38.0 °C or oxygen saturation 5 years old (adjusted annual incidence 12.0 per 100 person-years, influenza A virus was the most common virus (22% overall; 11% inpatients, 27% outpatients and Streptococcus pneumoniae was the most common bacteria (16% overall; 23% inpatients, 14% outpatients, yielding annual incidences of 2.6 and 1.7 episodes per 100 person-years, respectively. Influenza A virus, influenza B virus, respiratory syncytial virus (RSV and human metapneumovirus were more prevalent in swabs among cases (22%, 6%, 8% and 5%, respectively than controls. Adenovirus, parainfluenza viruses, rhinovirus/enterovirus, parechovirus, and Mycoplasma pneumoniae were not more prevalent among cases than controls. Pneumococcus and non-typhi Salmonella were more prevalent among HIV-infected adults, but prevalence of viruses was similar among HIV-infected and HIV-negative individuals. ARI incidence was highest during peak malaria season. CONCLUSIONS/SIGNIFICANCE: Vaccination against influenza and pneumococcus (by potential herd immunity from childhood vaccination or of HIV-infected adults might prevent much of the substantial ARI incidence among persons >5 years old in similar rural African settings.

    2013-04-01

    Childhood obesity is an issue of serious medical and social concern. In developing countries including India, it is a phenomenon seen in higher socioeconomic strata due to the adoption of a western lifestyle. Consumption of high calorie food, lack of physical activity and increased screen time are major risk factors for childhood obesity apart from other genetic, prenatal factors and socio-cultural practices. Obese children and adolescents are at increased risk of medical and psychological complications. Insulin resistance is commonly present especially in those with central obesity and manifests as dyslipidemia, type 2 diabetes mellitus, impaired glucose tolerance, hypertension, polycystic ovarian syndrome and metabolic syndrome. Obese children and adolescents often present to general physicians for management. The latter play a key role in prevention and treatment of obesity as it involves lifestyle modification of the entire family. This article aims at discussing the approach to diagnosis and work-up, treatment and preventive strategies for childhood obesity from a general physician's perspective.

    Despite progress toward assuring the health of today's young population, the 21(st) century began with an epidemic of childhood obesity. There is general agreement that the situation must be addressed by means of primary prevention, but relatively little is known about how to intervene effectively....... The evidence behind the assumption that childhood obesity can be prevented was discussed critically in this roundtable symposium. Overall, there was general agreement that action is needed and that the worldwide epidemic itself is sufficient evidence for action. As the poet, writer, and scholar Wittner Bynner...... (1881-1968) wrote, "The biggest problem in the world could have been solved when it was small"....

    Antibiotic resistance in Streptococcus pneumoniae is an emerging health problem worldwide. The incidence of antimicrobial-resistant S. pneumoniae is increasing, and nasal colonization of S. pneumoniae in children increases the risk of pneumococcal infection. In this study, the prevalence of S. pneumoniae nasal colonization was studied in Thai children from three different districts. S. pneumoniae nasal colonization was found in 38 of 237 subjects (16.0%). The carriage rate indicated higher rates in two rural districts (18.2% and 29.8%) than in the urban district (2.8%). The antibiotic susceptibility pattern was determined using the disk diffusion method. Prevalence of multi-drug resistance S. pneumoniae (MDR-SP) was 31.6%. Resistance to commonly prescribed antibiotics was found for ampicillin (5.3%), azithromycin (26.3%), cefepime (2.6%), chloramphenicol (18.4%), clindamycin (18.4%), erythromycin (21.1%), oxacillin (44.7%), trimethoprim/sulfamethoxazole (78.9%) and tetracycline (15.8%). All isolates were sensitive to ceftriaxone. The pulsed-field gel electrophoresis pattern was used to compare genetic diversity of the S. pneumoniae isolates. PFGE demonstrated the variation in genotypes of S. pneumoniae from different areas. High prevalence of multi-drug resistance S. pneumoniae nasal colonization in healthy Thai children was indicated. Effective strategies for appropriate use of antibiotics are therefore needed in the community.

    Objective: To evaluate the relationship between anthropometric measurements and Nursing Home-Acquired Pneumonia (NHAP) risk. Methods: Consecutive patients of 65 years or elderly who were living in the Balikli Rum Hospital Nursing Homes were included in this prospective study. At the beginning of this study, the patients’ anthropometrics values were measured. The patients were followed for one year, and any incidences of pneumonia attacks were recorded. The relationship between the anthropometric measurements and pneumonia occurrences was analyzed. Results: There were 133 inmates at the initial assessments. Of 108 patients who were eligible for the study, 77 (72.2%) were female and 37 (27.8%) were male. The mean age of the group was 79.8±10.5. Patients were assigned to a group according to the presence of pneumonia during the one -year follow-up. There were 74 (55.6%) patients who had suffered from at least one attack of pneumonia during the follow-up period. The mean triceps skinfold was significantly thinner in the pneumonia group, and the mean handgrip measurements in both the dominant and non-dominant hands were significantly weaker in the pneumonia group. Furthermore, the frequency of Chronic Obstructive Pulmonary Diseases (COPD) was significantly higher in this group (p < 0.001). Conclusions: The risk of pneumonia was high in the elderly population who live in nursing homes. Simple anthropometric values may be predictive of the potential for Nursing Home-Acquired Pneumonia.

    Klebsiella pneumoniae is a common cause of nosocomial pneumonia. Osteopontin (OPN) is a phosphorylated glycoprotein involved in inflammatory processes, some of which is mediated by CD44. The aim of this study was to determine the role of OPN during K. pneumoniae-induced pneumonia. Wild-type (WT) and OPN knockout (KO) mice were intranasally infected with 10⁴ colony forming units of K. pneumoniae, or administered Klebsiella lipopolysaccharides (LPS). In addition, recombinant OPN (rOPN) was intranasally administered to WT and CD44 KO mice. During Klebsiella pneumonia, WT mice displayed elevated pulmonary and plasma OPN levels. OPN KO and WT mice showed similar pulmonary bacterial loads 6 h after infection; thereafter, Klebsiella loads were higher in lungs of OPN KO mice and the mortality rate in this group was higher than in WT mice. Early neutrophil recruitment into the bronchoalveolar space was impaired in the absence of OPN after intrapulmonary delivery of either Klebsiella bacteria or Klebsiella LPS. Moreover, rOPN induced neutrophil migration into the bronchoalveolar space, independent from CD44. In vitro, OPN did not affect K. pneumoniae growth or neutrophil function. In conclusion, OPN levels were rapidly increased in the bronchoalveolar space during K. pneumoniae pneumonia, where OPN serves a chemotactic function towards neutrophils, thereby facilitating an effective innate immune response.

    The purpose of this study was to investigate the clinical characteristics of hypervirulent K. pneumoniae (hvKP) induced ventilator-associated pneumonia (VAP) and the microbiological characteristics and epidemiology of the hvKP strains. A retrospective study of 49 mechanically ventilated patients with K. pneumoniae induced VAP was conducted at a university hospital in China from January 2014 to December 2014. Clinical characteristics and K. pneumoniae antimicrobial susceptibility and biofilm formation were analyzed. Genes of capsular serotypes K1, K2, K5, K20, K54 and K57 and virulence factors plasmid rmpA(p-rmpA), iroB, iucA, mrkD, entB, iutA, ybtS, kfu and allS were also evaluated. Multilocus sequence typing (MLST) and random amplified polymorphic DNA (RAPD) analyses were used to study the clonal relationship of the K. pneumoniae strains. Strains possessed p-rmpA and iroB and iucA were defined as hvKP. Of 49 patients, 14 patients (28.6 %) were infected by hvKP. Antimicrobial resistant rate was significantly higher in cKP than that in hvKP. One ST29 K54 extended-spectrum-beta-lactamase (ESBL) producing hvKP strain was detected. The prevalence of K1 and K2 in hvKP was 42.9 % and 21.4 %, respectively. The incidences of K1, K2, K20, p-rmpA, iroB, iucA, iutA, Kfu and alls were significantly higher in hvKP than those in cKP. ST23 was dominant among hvKP strains, and all the ST23 strains had identical RAPD pattern. hvKP has become a common pathogen of VAP in mechanically ventilated patients in China. Clinicians should increase awareness of hvKP induced VAP and enhance epidemiologic surveillance.

    BACKGROUND: Of all hospitalised community-acquired pneumonias (CAPs) only a few are known to be caused by Chlamydia psittaci. Most likely the reported incidence, ranging from of 0% to 2.1%, is an underestimation of the real incidence, since detection of psittacosis is frequently not incorporated in

    Approximately 10% of children are obese. Twin and adoption studies demonstrate a large genetic component to obesity, especially in adults. However, the increasing prevalence of obesity over the last 20 years can only be explained by environmental factors. In most obese individuals, no measurable differences in metabolism can be detected. Few children engage in regular physical activity. Obese children and adults uniformly underreport the amount of food they eat. Obesity is particularly related to increased consumption of high-fat foods. BMI is a quick and easy way to screen for childhood obesity. Treating childhood obesity relies on positive family support and lifestyle changes involving the whole family. Food preferences are influenced early by parental eating habits, and when developed in childhood, they tend to remain fairly constant into adulthood. Children learn to be active or inactive from their parents. In addition, physical activity (or more commonly, physical inactivity) habits that are established in childhood tend to persist into adulthood. Weight loss is usually followed by changes in appetite and metabolism, predisposing individuals to regain their weight. However, when the right family dynamics exist--a motivated child with supportive parents--long-term success is possible.

    Findings on electrocardiogram may hint that pulmonary embolism (PE) is present when interpreted in the proper context and lead to definitive imaging tests. However, it would be useful to know if electrocardiographic (ECG) abnormalities also occur in patients with pneumonia and whether these are similar to ECG changes with PE. The purpose of this investigation was to determine ECG findings in patients with pneumonia. We retrospectively evaluated 62 adults discharged with a diagnosis of pneumonia who had no previous cardiopulmonary disease and had electrocardiogram obtained during hospitalization. The most prevalent ECG abnormality, other than sinus tachycardia, was minor nonspecific ST-segment or T-wave changes occurring in 13 of 62 (21%). Right atrial enlargement occurred in 4 of 62 (6.5%). QRS abnormalities were observed in 24 of 62 (39%). Right-axis deviation and S(1)S(2)S(3) were the most prevalent QRS abnormalities, which occurred in 6 of 62 (9.7%). Complete right bundle branch block and S(1)Q(3)T(3) pattern occurred in 3 of 62 (4.8%). ECG abnormalities that were not present within 1 month previously or abnormalities that disappeared within 1 month included left-axis deviation, right-axis deviation, right atrial enlargement, right ventricular hypertrophy, S(1)S(2)S(3), S(1)Q(3)T(3), low-voltage QRS complexes, and nonspecific ST-segment or T-wave abnormalities. In conclusion, electrocardiogram in patients with pneumonia often shows QRS abnormalities or nonspecific ST-segment or T-wave changes. ECG findings are similar to ECG abnormalities in PE and electrocardiogram cannot assist in the differential diagnosis.

    Full Text Available This study examined the spatial distribution of childhood community-acquired pneumonia detected through prospective surveillance in Goiânia, Brazil. Three spatial analysis techniques were applied to detect intra-urban geographic aggregation of pneumonia cases: Kernel method, nearest neighbor hierarchical technique, and spatial scan statistic. A total of 724 pneumonia cases confirmed by chest radiography were identified from May 2000 to August 2001. All cases were geocoded on a digital map. The annual pneumonia risk rate was estimated at 566 cases/100,000 children. Analysis using traditional descriptive epidemiology showed a mosaic distribution of pneumonia rates, while GIS methodologies showed a non-random pattern with hot spots of pneumonia. Cluster analysis by spatial scan statistic identified two high-risk areas for pneumonia occurrence, including one most likely cluster (RR = 2.1; p < 0.01 and one secondary cluster (RR = 1.3; p = 0.01. The data used for the study are in line with recent WHO-led efforts to improve and standardize pediatric pneumonia surveillance in developing countries and show how GIS and spatial analysis can be applied to discriminate target areas of pneumonia for public heath intervention.

    In medicine real severe mishaps are rare. On the other hand critical incidents are frequent. Anonymous critical incident reporting systems allow us to learn from these mishaps. This learning process will make our daily clinical work safer Unfortunately, before these systems can be used efficiently our professional culture has to be changed. Everyone in medicine has to admit that errors do occur to see the need for an open discussion. If we really want to learn from errors, we cannot punish the individual, who reported his or her mistake. The interest is primarily in what has happened and why it has happened and not who has committed this mistake. The cause for critical incidents in medicine is in over 80% the human factor Poor communication, work under enormous stress, conflicts and hierarchies are the main cause. This has been known for many years, therefore have already 15 years ago high-tech industries, like e.g. aviation, started to invest in special courses on team training. Medicine is a typical profession were until now only the individual performance decided about the professional career Communication, conflict management, stress management, decision making, risk management, team and team resource management were subjects that have never been taught during our preor postgraduate education. These points are the most important ones for an optimal teamwork. A multimodular course designed together with Swissair (Human Aspect Development medical, HADmedical) helps to cover, as in aviation, the soft factor and behavioural education in medicine and to prepare professionals in health care to work as a real team.

    Streptococcus pneumoniae is a major cause of meningitis, sepsis, and pneumonia worldwide. Pneumococcal conjugate vaccines have been part of the United Kingdom's childhood immunization program since 2006 and have significantly reduced the incidence of disease due to vaccine efficacy in reducing carriage in the population. Here we isolated two clones of 22F (an emerging serotype of clinical concern, multilocus sequence types 433 and 698) and conducted comparative genomic analysis on four isolates, paired by Sequence Type (ST) with one of each pair being derived from carriage and the other disease (sepsis). The most compelling observation was of nonsynonymous mutations in pgdA, encoding peptidoglycan N-acetylglucosamine deacetylase A, which was found in the carriage isolates of both ST433 and 698. Deacetylation of pneumococcal peptidoglycan is known to enable resistance to lysozyme upon invasion. Althought no other clear genotypic signatures related to disease or carriage could be determined, additional intriguing comparisons between the two STs were possible. These include the presence of an intact prophage, in addition to numerous additional phage insertions, within the carriage isolate of ST433. Contrasting gene repertoires related to virulence and colonization, including bacteriocins, lantibiotics, and toxin--antitoxin systems, were also observed.

    We investigated the incidence and 30-day case-fatality of childhood stroke in Estonia, and clinical signs and risk factors of childhood stroke. A retrospective (1995-2003) and prospective study (2004-2006) of childhood stroke (arterial ischemic, hemorrhagic, and sinovenous thrombosis) and transient ischemic attack was conducted. Stroke-incidence calculation was based on the prospective study. Clinical diagnoses of stroke were confirmed by neuroradiology. The incidence rate of childhood stroke in Estonia was 2.73/100,000 person-years for children aged 30 days to 18 years: 1.61/100,000 for arterial ischemic stroke, 0.87/100,000 for hemorrhagic stroke, 0.25/100,000 for sinovenous thrombosis, and 0.37/100,000 for transient ischemic attack. No arterial ischemic stroke patients died within 30 days, but case-fatality for intracerebral hemorrhage was 46%. Focal signs occurred in 100% of arterial ischemic strokes and 64% of intracerebral hemorrhage cases. Risk factors were identified in 35/48 (73%) children with cerebrovascular attacks. Six children with arterial ischemic stroke (6/24, 25%) manifested more than one risk factor. The incidence rate of childhood stroke in Estonia is similar to that in earlier data.

    Full Text Available Abstract Background Chile is currently undergoing a period of rapid demographic transition which has led to an increase in the proportion of older people in the population; the proportion aged 60 years and over, for example, increased from 8% of the population in 1980 to 12% in 2005. In an effort to promote healthy ageing and preserve function, the government of Chile has formulated a package of actions into the Programme of Complementary Feeding for the Older Population (PACAM which has been providing a nutritional supplement to older people since 1998. PACAM distributes micronutrient fortified foods to individuals aged 70 years and over registered at Primary Health Centres and enrolled in the programme. The recommended serving size (50 g/day of these supplements provides 50% of daily micronutrient requirements and 20% of daily energy requirements of older people. No information is currently available on the cost-effectiveness of the supplementation programme. Aim The aim of the CENEX cluster randomised controlled trial is to evaluate the cost-effectiveness of an ongoing nutrition supplementation programme, and a specially designed physical exercise intervention for older people of low to medium socio-economic status living in Santiago, Chile. Methods The study has been conceptualised as a public health programme effectiveness study and has been designed as a 24-month factorial cluster-randomised controlled trial conducted among 2800 individuals aged 65.0–67.9 years at baseline attending 28 health centres in Santiago. The main outcomes are incidence of pneumonia, walking capacity and change in body mass index over 24 months of intervention. Costing data (user and provider, collected at all levels, will enable the determination of the cost-effectiveness of the two interventions individually and in combination. The study is supported by the Ministry of Health in Chile, which is keen to expand and improve its national programme of nutrition for

    Klebsiella pneumoniae, a chief cause of nosocomial pneumonia, is a versatile and commonly multidrug-resistant human pathogen for which further insight into pathogenesis is needed. We show that the pilus regulatory gene fimK promotes the virulence of K. pneumoniae strain TOP52 in murine pneumonia. This contrasts with the attenuating effect of fimK on urinary tract virulence, illustrating that a single factor may exert opposing effects on pathogenesis in distinct host niches. Loss of fimK in TOP52 pneumonia was associated with diminished lung bacterial burden, limited innate responses within the lung, and improved host survival. FimK expression was shown to promote serum resistance, capsule production, and protection from phagocytosis by host immune cells. Finally, while the widely used K. pneumoniae model strain 43816 produces rapid dissemination and death in mice, TOP52 caused largely localized pneumonia with limited lethality, thereby providing an alternative tool for studying K. pneumoniae pathogenesis and control within the lung.

    Full Text Available Objective: Mechanical ventilator associated pneumonia is a serious infection occurred frequently in intensive care units and associated with high mortality. In this study we aimed to investigate the incidence of ventilator associated pneumonia, the duration of mechanical ventilation, length of intensive care unit stay, complication occurrence and mortality rates on patients undergoing mechanical ventilation for more than 48 hours. Material and Method: Two hundred twenty patients were included in the study. Demographic data at the time of the admission to intensive care unit (age, sex, height, weight and body mass index, intensive care admission diagnosis and systemic diseases were all recorded. The clinical pulmonary infection score was used for ventilator associated pneumonia diagnosis. Antibiotic usage, duration of stay in intensive care unit, duration of mechanical ventilation stay and mortality were all recorded. Results: Ventilator-associated pneumonia was detected in 51.36% (n=113 of the 220 patients. Clinical pulmonary infection score was found as 8.04±1.03 in patients with ventilator-associated pneumonia and 1.75±1.88 in non- ventilatorassociated pneumonia patients (p=0.001. Higher age was detected in ventilator-associated pneumonia group (58±12.79 years and 51.37±15.87 years, p=0.001. Also hypertension and diabetes mellitus were observed more frequently (p=0.001. Development of enteral nutrition in patients with ventilator-associated pneumonia were significantly higher than those of parenterally fed patients (enteral: by 36.4% and 25.5% p=0.006; parenteral: 25% and 19.1%, p=0.042.

    Community-acquired pneumonia (CAP) is one of the most common reasons for physician visits and hospitalizations in North America. Rates of CAP increase with age and CAP is associated with significant morbidity and mortality, especially in the elderly. Though there is much written about the epidemiology and risk factors of incident (first episode) pneumonia, much less is known about recurrent pneumonia. Rates of recurrent pneumonia within 3-5-years of an episode of CAP are 9-12% with a median time to recurrence of 123-317 days and mortality ranging from 4 to 10%. Age ≥65-years-old and impaired functional status are the only patient characteristics that are independently associated with increased risk of recurrence. In terms of modifiable risk factors, only the use of proton-pump inhibitors and systemic and inhaled corticosteroids have consistently been associated with increased risk of recurrent pneumonia, while angiotensin-converting enzyme (ACE) inhibitors may exert a protective effect. Many chronic medical conditions typically associated with increased incident pneumonia-such as chronic obstructive pulmonary disease (COPD), neurological disease (resulting in dysphagia or silent aspiration), and heart failure-were not associated with increased risk of recurrent pneumonia. However, those who are immune-suppressed (e.g., immunoglobulin deficiencies) may be at increased risk of recurrent pneumonia. In summary, among those who survive an episode of pneumonia, recurrence is not uncommon, particularly in the elderly. Following recovery from an episode of pneumonia, patients should be evaluated for risk factors that would predispose to a second episode including seeking evidence of immunosuppression in younger patients and medication optimization, particularly in the elderly.

    Despite the existence of low-cost and effective interventions for childhood pneumonia and diarrhoea, these conditions remain two of the leading killers of young children. Based on feedback from health professionals in countries with high child mortality, in 2009, WHO and Unicef began conceptualising an integrated approach for pneumonia and diarrhoea control. As part of this initiative, WHO and Unicef, with support from other partners, conducted a series of five workshops to facilitate the inclusion of coordinated actions for pneumonia and diarrhoea into the national health plans of 36 countries with high child mortality. This paper presents the findings from workshop and post-workshop follow-up activities and discusses the contribution of these findings to the development of the integrated Global Action Plan for the Prevention and Control of Pneumonia and Diarrhoea, which outlines the necessary actions for elimination of preventable child deaths from pneumonia and diarrhoea by 2025. Though this goal is ambitious, it is attainable through concerted efforts. By applying the lessons learned thus far and continuing to build upon them, and by leveraging existing political will and momentum for child survival, national governments and their supporting partners can ensure that preventable child deaths from pneumonia and diarrhoea are eventually eliminated.

    Nursing- and healthcare-associated pneumonia (NHCAP) has been proposed by the Japanese Respiratory Society as a new category of pneumonia considering the characteristics of the Japanese medical care environment. It is necessary to ascertain the epidemiology and clinical outcomes of NHCAP. A prospective study was conducted of patients with pneumonia who were hospitalized at our hospital from August 2011 to July 2012. We compared 192 cases of NHCAP with 114 cases of community-acquired pneumonia (CAP). Compared with CAP, NHCAP had a higher disease severity, higher 30-day mortality rate (10.9 vs. 3.5 %, P = 0.022), and longer length of hospital stay (median, 12 vs. 8 days, P pneumoniae was the most frequent causative pathogen in both NHCAP and CAP (33.9 vs. 34.8 %, P = 0.896). The incidence of atypical pathogens in NHCAP was low (1.7 %). Multidrug-resistant (MDR) pathogens were isolated more frequently in NHCAP than in CAP, but there was no significant difference (11.0 vs. 4.5 %, P = 0.135). Among 192 NHCAP patients, 122 (63.5 %) were aspiration pneumonia. Aspiration pneumonia was associated with poor outcomes and was considered a major characteristic of NHCAP. Our study suggested that many patients with NHCAP do not need broad-spectrum antibiotic therapy targeting MDR pathogens. Excess mortality in NHCAP patients is the result of patient backgrounds or disease severity rather than the presence of MDR pathogens.

    Acute pancreatitis is a rare finding in childhood but probably more common than is generally realized. This condition should be considered in the evaluation of children with vomiting and abdominal pain, because it can cause significant morbidity and mortality. Clinical suspicion is required to make the diagnosis, especially when the serum amylase concentration is normal. Recurrent pancreatitis may be familial as a result of inherited biochemical or anatomic abnormalities. Patients with hereditary pancreatitis are at high risk for pancreatic cancer.

    1. 13,460 men, or about 80 per cent of the entire camp strength, were vaccinated against pneumonia with pneumococcus lipovaccine. 2. The dosage employed in all cases was 1 cc. of the lipovaccine containing approximately 10 billion each of Pneumococcus Types I, II, and III. 3. Both the local and general reactions produced by the vaccine were usually mild. Only 0.7 per cent of those who received the vaccine were sufficiently affected to need hospital care. None of these was seriously ill, and a majority of them returned to duty on the 2nd or 3rd day after admission. 4. Most of the troops inoculated were under observation for 2 or 3 months after vaccination. During this period there were 32 cases of Pneumococcus Type I, II, and III pneumonia among the vaccinated four-fifths of camp, and 42 cases of pneumonia of these types among the unvaccinated one-fifth of camp. If, however, all cases of pneumonia that developed within 1 week after vaccination are excluded from the vaccinated group, there remain only 8 cases of pneumonia produced by fixed types, and these were all secondary to severe attacks of influenza. This exclusion is justified by the fact that protective bodies do not begin to appear in the serum until the 8th day after injection of pneumococcus lipovaccine. 5. There is no evidence whatever that pneumococcus vaccine predisposes the individual even temporarily toward either pneumococcus or streptococcus pneumonia. 6. The weekly incidence rate for pneumonia (all types) among the vaccinated troops was conspicuously lower than that for the unvaccinated troops. 7. The pneumonia incidence rate per 1,000 men during the period of the experiment was twice as high for unvaccinated recruits as for vaccinated recruits, and nearly seven times as high for unvaccinated seasoned men as for vaccinated seasoned men. 8. Influenza causes a marked reduction in resistance to pneumonia even among vaccinated men. Of the 155 cases of pneumonia (all types) developing 1 week or more

    Full Text Available OBJECTIVE : To analyze studies that evaluated the role of infections as well as indirect measures of exposure to infection in the risk of childhood leukemia, particularly acute lymphoblastic leukemia. METHODS : A search in Medline, Lilacs, and SciELO scientific publication databases initially using the descriptors “childhood leukemia” and “infection” and later searching for the words “childhood leukemia” and “maternal infection or disease” or “breastfeeding” or “daycare attendance” or “vaccination” resulted in 62 publications that met the following inclusion criteria: subject aged ≤ 15 years; specific analysis of cases diagnosed with acute lymphoblastic leukemia or total leukemia; exposure assessment of mothers’ or infants’ to infections (or proxy of infection, and risk of leukemia. RESULTS : Overall, 23 studies that assessed infections in children support the hypothesis that occurrence of infection during early childhood reduces the risk of leukemia, but there are disagreements within and between studies. The evaluation of exposure to infection by indirect measures showed evidence of reduced risk of leukemia associated mainly with daycare attendance. More than 50.0% of the 16 studies that assessed maternal exposure to infection observed increased risk of leukemia associated with episodes of influenza, pneumonia, chickenpox, herpes zoster, lower genital tract infection, skin disease, sexually transmitted diseases, Epstein-Barr virus, and Helicobacter pylori . CONCLUSIONS : Although no specific infectious agent has been identified, scientific evidence suggests that exposure to infections has some effect on childhood leukemia etiology.

    Lymphocytic interstitial pneumonia (LIP) is a rare lung disease on the spectrum of benign pulmonary lymphoproliferative disorders. LIP is frequently associated with connective tissue diseases or infections. Idiopathic LIP is rare; every attempt must be made to diagnose underlying conditions when LIP is diagnosed. Computed tomography of the chest in patients with LIP may reveal ground-glass opacities, centrilobular and subpleural nodules, and randomly distributed thin-walled cysts. Demonstrating polyclonality with immunohistochemistry is the key to differentiating LIP from lymphoma. The 5-year mortality remains between 33% and 50% and is likely to vary based on the underlying disease process.

    Children with poor nutrition are at increased risk of pneumonia. In many tropical settings seasonal pneumonia epidemics occur during the rainy season, which is often a period of poor nutrition. We have investigated whether seasonal hunger may be a driver of seasonal pneumonia epidemics in children in the tropical setting of the Philippines. In individual level cohort analysis, infant size and growth were both associated with increased pneumonia admissions, consistent with findings from previous studies. A low weight for age z-score in early infancy was associated with an increased risk of pneumonia admission over the following 12 months (RR for infants in the lowest quartile of weight for age z-scores 1.28 [95% CI 1.08 to 1.51]). Poor growth in smaller than average infants was also associated with an increased risk of pneumonia (RR for those in the lowest quartile of growth in early infancy 1.31 [95%CI 1.02 to 1.68]). At a population level, we found that seasonal undernutrition preceded the seasonal increase in pneumonia and respiratory syncytial virus admissions by approximately 10 weeks (pairwise correlation at this lag was -0.41 [95%CI -0.53 to -0.27] for pneumonia admissions, and -0.63 [95%CI -0.72 to -0.51] for respiratory syncytial virus admissions). This lag appears biologically plausible. These results suggest that in addition to being an individual level risk factor for pneumonia, poor nutrition may act as a population level driver of seasonal pneumonia epidemics in the tropics. Further investigation of the seasonal level association, in particular the estimation of the expected lag between seasonal undernutrition and increased pneumonia incidence, is recommended.

    Full Text Available Background: Childhood bacterial meningitis is a neurologic emergency that continues to kill and maims children particularly in developing countries with poor immunization coverage. Objective: This study set out to assess the hospital incidence, pattern of presentation, etiologic agents, outcome and determinants of mortality among the children admitted with bacterial meningitis at the Wesley Guild Hospital (WGH, Ilesa. Patients and Methods: We carried out a retrospective review of admitted cases of bacterial meningitis in children aged one month to 15 years at the WGH, Ilesa over a three year period by looking at the hospital records. Factors in the history and examinations were compared among survivors and those that died to determine factors significantly associated with mortality in these children. Results: Eighty-one (5.5% of the 1470 childhood admissions during the study period had bacterial meningitis. Male preponderance was observed and two-thirds of the children were infants. More cases were admitted during the wet rainy season than during the dry harmattan season. Haemophilus influenzae type B and Streptococcus pneumoniae were the leading etiologic agents and ciprofloxacin and ceftriaxone adequately cover for these organisms. Twenty-two (27.2% of the 81 children died, while 34 (42.0% survived with neurologic deficits. Children with multiple seizures, coma, neck retraction, hyponatremia, hypoglycorrhachia, turbid CSF as well as Gram positive meningitis at presentation were found to more likely to die (P < 0.05. None of these factors however independently predict mortality. Conclusion: Childhood bacterial meningitis often results in death and neurologic deficit among infants and young children admitted at the WGH, Ilesa. Children diagnosed with meningitis who in addition had multiple seizures, neck retraction and coma at presentation are at increased risk of dying.

    Streptococcus pneumoniae is the most common causative pathogen in community-acquired pneumonia (CAP). Granzyme A (GzmA) is a serine protease produced by a variety of cell types involved in the immune response. We sought to determine the role of GzmA on the host response during pneumococcal pneumonia. GzmA was measured in bronchoalveolar lavage fluid (BALF) harvested from CAP patients from the infected and contralateral uninfected side and in lung tissue slides from CAP patients and controls. In CAP patients, GzmA levels were increased in BALF obtained from the infected lung. Human lungs showed constitutive GzmA expression by both parenchymal and nonparenchymal cells. In an experimental setting, pneumonia was induced in wild-type (WT) and GzmA-deficient (GzmA(-/-)) mice by intranasal inoculation of S. pneumoniae In separate experiments, WT and GzmA(-/-) mice were treated with natural killer (NK) cell depleting antibodies. Upon infection with S. pneumoniae, GzmA(-/-) mice showed a better survival and lower bacterial counts in BALF and distant body sites compared with WT mice. Although NK cells showed strong GzmA expression, NK cell depletion did not influence bacterial loads in either WT or GzmA(-/-) mice. These results implicate that GzmA plays an unfavorable role in host defense during pneumococcal pneumonia by a mechanism that does not depend on NK cells.

    Full Text Available Introduction: Pneumococcal infections are important cause of morbidity and mortality. Knowledge of antimicrobial susceptibility patterns plays important role in the selection of appropriate therapy. Present study was undertaken to analyze the susceptibility patterns of pneumococcal isolates against commonly used antimicrobials with special reference to determination of minimum inhibitory concentration (MIC of penicillin in a tertiary care hospital in eastern Nepal. Methods: Twenty-six strains of S. pneumoniae isolated from various clinical specimens submitted to microbiology laboratory were evaluated. All isolates were tested for antimicrobial susceptibility by disk diffusion method. MIC of penicillin was tested by broth dilution method. Results: Of the total isolates 19 (73% were from invasive infections. Seven isolates were resistant to cotrimoxazole. No resistance to penicillin was seen in disk diffusion testing. Less susceptibility to penicillin (MIC 0.1-1.0 mg/L was observed in five (17% isolates. High level resistance to penicillin was not detected. One isolate was multidrug resistant. Conclusions: S. pneumoniaeisolates with intermediate resistance to penicillin prevail in Tertiary Care Hospital in eastern Nepal, causing invasive and noninvasive infections. As intermediate resistance is not detected in routine susceptibility testing, determination of MIC is important. It helps not only in the effective management of life threatening infections but is also essential in continuous monitoring and early detection of resistance. In addition, further study on pneumococcal infections, its antimicrobial resistance profile and correlation with clinical and epidemiological features including serotypes and group prevalence is recommended in future. Keywords: antimicrobial susceptibility pattern, penicillin, Streptococcus pneumoniae.

  19. Population-based incidence of typhoid fever in an urban informal settlement and a rural area in Kenya: implications for typhoid vaccine use in Africa.

    Directory of Open Access Journals (Sweden)

    Robert F Breiman

    Full Text Available BACKGROUND: High rates of typhoid fever in children in urban settings in Asia have led to focus on childhood immunization in Asian cities, but not in Africa, where data, mostly from rural areas, have shown low disease incidence. We set out to compare incidence of typhoid fever in a densely populated urban slum and a rural community in Kenya, hypothesizing higher rates in the urban area, given crowding and suboptimal access to safe water, sanitation and hygiene. METHODS: During 2007-9, we conducted population-based surveillance in Kibera, an urban informal settlement in Nairobi, and in Lwak, a rural area in western Kenya. Participants had free access to study clinics; field workers visited their homes biweekly to collect information about acute illnesses. In clinic, blood cultures were processed from patients with fever or pneumonia. Crude and adjusted incidence rates were calculated. RESULTS: In the urban site, the overall crude incidence of Salmonella enterica serovar Typhi (S. Typhi bacteremia was 247 cases per 100,000 person-years of observation (pyo with highest rates in children 5-9 years old (596 per 100,000 pyo and 2-4 years old (521 per 100,000 pyo. Crude overall incidence in Lwak was 29 cases per 100,000 pyo with low rates in children 2-4 and 5-9 years old (28 and 18 cases per 100,000 pyo, respectively. Adjusted incidence rates were highest in 2-4 year old urban children (2,243 per 100,000 pyo which were >15-fold higher than rates in the rural site for the same age group. Nearly 75% of S. Typhi isolates were multi-drug resistant. CONCLUSIONS: This systematic urban slum and rural comparison showed dramatically higher typhoid incidence among urban children <10 years old with rates similar to those from Asian urban slums. The findings have potential policy implications for use of typhoid vaccines in increasingly urban Africa.

    Pneumonia is a frequent complication in dementia patients and is associated with high mortality rates. The aim of this retrospective cohort study was to determine whether traditional Chinese medicine (TCM) therapy can decrease pneumonia risk in dementia patients. The cohort dataset was obtained from the Longitudinal Health Insurance Database 2005, a sublibrary of the National Health Insurance Research Database, containing all medical data of 1 million beneficiaries, randomly selected from the all Insurers in year 2005.Newly diagnosed dementia patients (n = 9712) without pneumonia were analyzed from January 1997 to December 2003. After matching by sex, age, urban level, Charlson comorbidity index, insured amount, and comorbidities, 1376 pairs (1:1) of TCM and non-TCM users were acquired. Every dementia patient was individually recorded from 1997 to 2012 to identify pneumonia incidence (onset after 3 months of dementia diagnosis).Demographic characteristics, Charlson comorbidity index, comorbidities, behavioral and psychological symptoms of dementia, and psychotropic drugs were also investigated. Cox proportional regression was used to compute hazard ratios and 95% confidence intervals (CIs) after adjustment for the above-mentioned variables.There were 419 (30.5%) and 762 (55.4%) pneumonia cases in the TCM and non-TCM cohorts during a mean follow-up period of 7.6 years. The adjusted hazard ratios (95% CI) for pneumonia admission was 0.62 (0.55-0.70) for the TCM group.Patients who received TCM therapy at higher cumulative doses or for longer periods experienced increased protection from pneumonia admission. Ma-Xing-Gan-Shi-Tang, Yin-Qiao-San, and Xiao-Qing-Long-Tang might represent possible formulae reducing the incidence of pneumonia. TCM might be associated with a lower risk of pneumonia in dementia patients.

    Full Text Available Background. Routine vaccination against Streptococcus pneumoniae is recommended in Canada for infants, the elderly, and individuals with chronic comorbidity. National incidence and burden of all-cause and pneumococcal pneumonia in Canada (excluding Quebec were assessed. Methods. Incidence, length of stay, and case-fatality rates of hospitalized all-cause and pneumococcal pneumonia were determined for 2004–2010 using ICD-10 discharge data from the Canadian Institutes for Health Information Discharge Abstract Database. Population-at-risk data were obtained from the Statistics Canada census. Temporal changes in pneumococcal and all-cause pneumonia rates in adults ≥65 years were analyzed by logistic regression. Results. Hospitalization for all-cause pneumonia was highest in children 70 years and declined significantly from 1766/100,000 to 1537/100,000 per year in individuals aged ≥65 years (P<0.001. Overall hospitalization for pneumococcal pneumonia also declined from 6.40/100,000 to 5.08/100,000 per year. Case-fatality rates were stable (11.6% to 12.3%. Elderly individuals had longer length of stay and higher case-fatality rates than younger groups. Conclusions. All-cause and pneumococcal pneumonia hospitalization rates declined between 2004 and 2010 in Canada (excluding Quebec. Direct and indirect effects from pediatric pneumococcal immunization may partly explain some of this decline. Nevertheless, the burden of disease from pneumonia remains high.

  8. Ventilator associated pneumonia and infection control

    2006-04-01

    Full Text Available Abstract Ventilator associated pneumonia (VAP is the leading cause of morbidity and mortality in intensive care units. The incidence of VAP varies from 7% to 70% in different studies and the mortality rates are 20–75% according to the study population. Aspiration of colonized pathogenic microorganisms on the oropharynx and gastrointestinal tract is the main route for the development of VAP. On the other hand, the major risk factor for VAP is intubation and the duration of mechanical ventilation. Diagnosis remains difficult, and studies showed the importance of early initiation of appropriate antibiotic for prognosis. VAP causes extra length of stay in hospital and intensive care units and increases hospital cost. Consequently, infection control policies are more rational and will save money.

    2016-05-01

    Acute mastoiditis (AM) is a relatively rare complication of acute otitis media (AOM). The most common pathogens include Streptococcus pneumoniae, Streptococcus pyogenes, and Staphylococcus aureus. Pneumococcal vaccination and changes in antibiotic prescribing recommendations for AOM may change the incidence of AM in the future. Diagnosis of AM can be made based on clinical presentation, but computed tomography of the temporal bone with contrast should be considered if there is concern for complicated AM. Both extracranial and intracranial complications of AM may occur. Previously, routine cortical mastoidectomy was recommended for AM treatment, but new data suggest that a more conservative treatment approach can be considered, including intravenous (IV) antibiotics alone or IV antibiotics with myringotomy.

    Idiopathic interstitial pneumonias comprise 8 clinicopathological entities, most of them with a chronic course and various prognosis. Idiopathic pulmonary fibrosis is the most frequent and most severe of these. Computed tomography has an important role for its diagnosis. It can identify the corresponding pathological pattern of usual interstitial pneumonia in about 50 percent of cases. It can suggest differential diagnosis in other cases, most frequently fibrosing nonspecific interstitial pneumonia and chronic hypersensitivity pneumonitis. Imaging features should be integrated to clinical and available pathologic data during multidisciplinary team meetings involving physicians with a good knowledge of interstitial diseases. Some cases may be unclassifiable, but these could later be reclassified as new data may occur or imaging features may change. Surgical lung biopsy is being less frequently performed and an emerging less invasive technique, lung cryobiopsy, is under evaluation. Pleuroparenchymal fibroelastosis is a distinct entity only recently described, with uncertain prevalence and prognosis that seems being quite often associated to another pattern of interstitial pneumonia.

    This document updates and replaces CDC's previously published "Guideline for Prevention of Nosocomial Pneumonia" (Infect Control 1982;3:327-33, Respir Care 1983;28:221-32, and Am J Infect Control 1983;11:230-44). This revised guideline is designed to reduce the incidence of nosocomial pneumonia and is intended for use by personnel who are responsible for surveillance and control of infections in acute-care hospitals; the information may not be applicable in long-term-care facilities because of the unique characteristics of such settings. This revised guideline addresses common problems encountered by infection-control practitioners regarding the prevention and control of nosocomial pneumonia in U.S. hospitals. Sections on the prevention of bacterial pneumonia in mechanically ventilated and/or critically ill patients, care of respiratory-therapy devices, prevention of cross-contamination, and prevention of viral lower respiratory tract infections (e.g., respiratory syncytial virus [RSV] and influenza infections) have been expanded and updated. New sections on Legionnaires disease and pneumonia caused by Aspergillus sp. have been included. Lower respiratory tract infection caused by Mycobacterium tuberculosis is not addressed in this document. Part I, "An Overview of the Prevention of Nosocomial Pneumonia, 1994, provides the background information for the consensus recommendations of the Hospital Infection Control Practices Advisory Committee (HICPAC) in Part II, Recommendations for Prevention of Nosocomial Pneumonia." Pneumonia is the second most common nosocomial infection in the United States and is associated with substantial morbidity and mortality. Most patients who have nosocomial pneumonia are infants, young children, and persons > 65 years of age; persons who have severe underlying disease, immunosuppression, depressed sensorium, and/or cardiopulmonary disease and persons who have had thoracoabdominal surgery.

    Full Text Available Psoriasis is a prevalent autoimmune disorder. Various studies have reported on the relationship between psoriasis and chronic diseases but very few have explored the association between psoriasis and subsequent acute infection. This retrospective cohort study aimed to compare the risk of pneumonia between subjects with and those without psoriasis.The medical records of 14,022 patients with psoriasis and 14,022 without psoriasis were obtained from the Taiwan Longitudinal Health Insurance Database 2000. Each patient was followed-up for a three-year period. Cox proportional hazard regressions were performed to compare difference of subsequent pneumonia incidence between subjects with and those without psoriasis.There were 206 (1.47% subjects with psoriasis and 138 (0.98% without psoriasis hospitalized for pneumonia. By Cox proportional hazard regressions analysis, the HR (hazard ratio of pneumonia requiring hospitalization for patients with psoriasis was 1.50 (95% confidence interval [CI]: 1.21-1.86 compared to patients without psoriasis. The adjusted HR was 1.40 (95% CI: 1.12-1.73. The adjusted HR of pneumonia hospitalization for subjects with mild and severe psoriasis was 1.36 (95% CI: 1.09-1.70 and 1.68 (95% CI: 1.12-2.52, respectively, compared to those without psoriasis.Patients with psoriasis have significantly higher incidence of pneumonia compared to those without psoriasis.

  14. A systematic review on the diagnosis of pediatric bacterial pneumonia: when gold is bronze.

    Directory of Open Access Journals (Sweden)

    Tim Lynch

    Full Text Available BACKGROUND: In developing countries, pneumonia is one of the leading causes of death in children under five years of age and hence timely and accurate diagnosis is critical. In North America, pneumonia is also a common source of childhood morbidity and occasionally mortality. Clinicians traditionally have used the chest radiograph as the gold standard in the diagnosis of pneumonia, but they are becoming increasingly aware that it is not ideal. Numerous studies have shown that chest radiography findings lack precision in defining the etiology of childhood pneumonia. There is no single test that reliably distinguishes bacterial from non-bacterial causes. These factors have resulted in clinicians historically using a combination of physical signs and chest radiographs as a 'gold standard', though this combination of tests has been shown to be imperfect for diagnosis and assigning treatment. The objectives of this systematic review are to: 1 identify and categorize studies that have used single or multiple tests as a gold standard for assessing accuracy of other tests, and 2 given the 'gold standard' used, determine the accuracy of these other tests for diagnosing childhood bacterial pneumonia. METHODS AND FINDINGS: Search strategies were developed using a combination of subject headings and keywords adapted for 18 electronic bibliographic databases from inception to May 2008. Published studies were included if they: 1 included children one month to 18 years of age, 2 provided sufficient data regarding diagnostic accuracy to construct a 2x2 table, and 3 assessed the accuracy of one or more index tests as compared with other test(s used as a 'gold standard'. The literature search revealed 5,989 references of which 256 were screened for inclusion, resulting in 25 studies that satisfied all inclusion criteria. The studies examined a range of bacterium types and assessed the accuracy of several combinations of diagnostic tests. Eleven different gold

    In industrial countries, 1 child out of 500 develops a cancer before the age of 15 years, and before the age of 6 years for almost half of them. In France, incidence rates were stable over the 15 last years with around 1500 cases each year. A very small fraction of cases is attributable to known risk factors, including heritable cancers or cancers in children with heritable predisposing diseases, cancers induced by high doses of ionizing radiation of medical or accidental origin, by chemotherapeutic or immunosuppressive drugs. Responsibility of Epstein Barr virus in a fraction of Hodgkin's and Burkitt's lymphomas is also established, even though little is still known on the cofactors involved in industrial countries. Other virus could cause leukaemia, as suggested by localized increases in incidence in various conditions of population mixing. Conversely, there is some evidence that early common infections could be protective toward leukaemia risk, probably through their contribution to the maturation of the immune system. Several agents are suspected to induce chemical cancers, particularly pesticides, which are consistently reported in childhood leukaemia and brain tumours. It is more and more likely that genetic factors may modulate risk induced of environmental factors.

  16. Ventilator Circuits, Humidification and Ventilator-Associated Pneumonia

    Directory of Open Access Journals (Sweden)

    Dean Hess

    1996-01-01

    Full Text Available Technical issues in the care of mechanically ventilated patients include those related to the ventilator circuit, humidification and ventilator-associated pneumonia. Principal issues related to ventilator circuits include leaks and compression volume. Circuit compression volume affects delivered tidal volume as well as measurements of auto-positive end-expiratory pressure and mixed expired PCO2. Resistance through the ventilator circuit contributes to patient-ventilator dyssynchrony during assisted modes of mechanical ventilation. Adequate humidification of inspired gas is necessary to prevent heat and moisture loss. Common methods of humidification of inspired gas during mechanical ventilation include use of active heated humidifiers and passive artificial noses. Artificial noses are less effective than active humidifiers and are best suited to short term use. With active humidifiers, the circuit can be heated to avoid condensate formation. However, care must be exercised when heated circuits are used to avoid delivery of a low relative humidity and subsequent drying of secretions in the artificial airway. Although pneumonia is a complication of mechanical ventilation, these pneumonias are usually the result of aspiration of pharyngeal secretions and are seldom related to the ventilator circuit. Ventilator circuits do not need to be changed more frequently than weekly for infection control purposes, and the incidence of ventilator-associated pneumonia may be greater with more frequent circuit changes.

High global incidence of macrolide and penicillin resistance has been reported, whereas fluoroquinolone resistance is uncommon. Current guidelines for suspected CAP in patients with co-morbidity factors and recent antibiotic therapy recommend initial empiric therapy using one fluoroquinolone or one macrolide associated to other drugs (amoxicillin, amoxicillin/clavulanate, broad-spectrum cephalosporins. Resistance to fluoroquinolones is determined by efflux mechanisms and/or mutations in the parC and parE genes coding for topoisomerase IV and/or gyrA and gyrB genes coding for DNA gyrase. No clinical cases due to fluoroquinolone-resistant S. pneumoniae strains have been yet reported from Italy. Case presentation A 72-year-old patient with long history of chronic obstructive pulmonary disease and multiple fluoroquinolone treatments for recurrent lower respiratory tract infections developed fever, increased sputum production, and dyspnea. He was treated with oral levofloxacin (500 mg bid. Three days later, because of acute respiratory insufficiency, the patient was hospitalized. Levofloxacin treatment was supplemented with piperacillin/tazobactam. Microbiological tests detected a S. pneumoniae strain intermediate to penicillin (MIC, 1 mg/L and resistant to macrolides (MIC >256 mg/L and fluoroquinolones (MIC >32 mg/L. Point mutations were detected in gyrA (Ser81-Phe, parE (Ile460-Val, and parC gene (Ser79-Phe; Lys137-Asn. Complete clinical response followed treatment with piperacillin/tazobactam. Conclusion This is the first Italian case of community-acquired pneumonia due to a fluoroquinolone-resistant S. pneumoniae isolate where treatment failure of levofloxacin was documented. Molecular analysis showed a group of mutations that have not yet been reported from Italy and has been detected only twice in Europe. Treatment with piperacillin

    Pneumonia is a common and potentially serious infectious disease. Morbidity and mortality rates continue to be high in spite of major advances and steady progress in diagnosis and treatment. The economic impact of the disease is also great. It is therefore necessary to enlist the public, primary care and emergency physicians, and public policy administrators to join forces to treat and prevent pneumonia for the common good. The annual incidence of pneumonia in the population over the age of 14 years is 1.6 to 2.6 episodes/1000 inhabitants. The mortality rate is 14.1 per 100,000 inhabitants, and the associated costs are 115 million euros annually. The RESPIRA Foundation and the Spanish Society of Pulmonology and Thoracic Surgery (SEPAR) declared 2004 to be pneumonia awareness year with the aim of coordinating efforts to raise awareness, distribute information, and foster debate.

    Examined the sexual history of 2,003 young women to determine whether childhood sexual abuse contributed to a greater risk for teenage pregnancy. Results indicate that sexual abuse alone was not related to the incidence of teenage pregnancy, but sexual precocity was related to much higher incidences of teenage pregnancy. (RJM)

  20. Estimating pneumonia deaths of post-neonatal children in countries of low or no death certification in 2008.

    Full Text Available BACKGROUND: Pneumonia is the leading cause of child deaths globally. The aims of this study were to: a estimate the number and global distribution of pneumonia deaths for children 1-59 months for 2008 for countries with low (85% coverage of death certification countries was used. For 87 high child-mortality countries pneumonia death estimates were obtained by applying a regression model developed from published and unpublished verbal autopsy data from high child-mortality settings. The total number of 1-59 months pneumonia deaths for the year 2008 for these 122 countries was estimated to be 1.18 M (95% CI 0.77 M-1.80 M, which represented 23.27% (95% CI 17.15%-32.75% of all 1-59 month child deaths. The country level estimation correlation coefficient between these two methods was 0.40. INTERPRETATION: Although the overall number of post-neonatal pneumonia deaths was similar irrespective to the method of estimation used, the country estimate correlation coefficient was low, and therefore country-specific estimates should be interpreted with caution. Pneumonia remains the leading cause of child deaths and is greatest in regions of poverty and high child-mortality. Despite the concerns about gender inequity linked with childhood mortality we could not estimate sex-specific pneumonia mortality rates due to the inadequate data. Life-saving interventions effective in preventing and treating pneumonia mortality exist but few children in high pneumonia disease burden regions are able to access them. To achieve the United Nations Millennium Development Goal 4 target to reduce child deaths by two-thirds in year 2015 will require the scale-up of access to these effective pneumonia interventions.

    Community-acquired pneumonia (CAP) is an important cause of mortality and morbidity amongst adults in the Asia-Pacific region. Literature published between 1990 and May 2010 on the clinical and economic burden of CAP amongst adults in this region was reviewed. CAP is a significant health burden with significant economic impact in this region. Chronic obstructive pulmonary disease, cardiovascular disease, diabetes mellitus and advanced age were risk factors for CAP. Aetiological agents included Streptococcus pneumoniae, Klebsiella pneumoniae, Gram-negative bacteria, Mycobacterium tuberculosis, Burkholderia pseudomallei, Staphylococcus aureus and atypical pathogens (Mycoplasma pneumoniae, Chlamydophila pneumoniae and Legionella spp.), with important differences in the prevalence of these pathogens within the region. Antibiotic resistance was significant but was not linked to excess mortality. Aetiological pathogens remained susceptible to newer antimicrobial agents. Rational antibiotic use is essential for preventing resistance, and increased surveillance is required to identify future trends in incidence and aetiology and to drive treatment and prevention strategies.

    Full Text Available Klebsiella pneumoniae is a Gram-negative enterobacterium that has historically been and currently remains, a significant cause of human disease and several kinds of infections in animals. In the present work, trials for the isolation of Klebsiella pneumoniae from diseased and apparently healthy farm animals (cows, sheep, goats and camels were done for recognition of Klebsiella pneumoniae subspecies. It was noticed that there was a marked variation between incidences of Klebsiella pneumoniae subspecies in examined animals as regards to health condition. The frequency was greater among samples collected from diseased animals 25.2% as compared with apparently healthy one 5.5%. It was found that there was great difference between the prevalence of Klebsiella isolated from various animal origins. On biochemical identification Klebsiella pneumoniae subsp. pneumoniae was the most prevalent followed by Klebsiella pneumoniae subsp. ozaenae and Klebsiella pneumoniae subsp. Rhinoscleromatis. Klebsiella pneumoniae subsp. rhinoscleromatis was not isolated from apparently healthy animals. The in vitro sensitivity of isolates of Klebsiella pneumoniae subspecies recovered from different animal species to 23 antimicrobial agents was tested. It was found that were resistance to cefoxitin, cefotaxime, cefoperazone, ceftazidime, ceftriaxone, aztreonam, amoxicillin and ampicillin. The most potent antibiotics showing 100% activity against Klebsiella pneumoniae subsp. isolated in this study were imipenem, ciprofloxacin, norfloxacin, gentamicin and kanamycin. While 96.2% of all examined isolates were sensitive to amoxicillin/clavulanic acid and ticarcillin/clavulanic acid. SDS-PAGE analysis showed that CPSs of Klebsiella pneumoniae subspecies contained wide variety of different molecular weights which ranged from 15.52 kDa to106.29 kDa and gave 10-13 bands. Evaluation of humoral immune response of mice immunized with CPSs was done using ELISA. It was found that the

    Interstitial pneumonia (IP) and chronic obstructive pulmonary disease (COPD) are representative diseases of restrictive pulmonary dysfunction and obstructive pulmonary dysfunction, respectively. In the preoperative anesthesia clinic, anesthesiologists are frequently asked to assess the anesthesia management of patients with these diseases. In respiratory function tests, IP is detected as a decrease in % vital capacity (< 80%), and COPD as a decrease in % FEV1.0 (< 70%). Other key factors which affect the assessment are; 1) severity assessment that affects the safety of anesthesia management, 2) prognostic evaluation including the acute exacerbation in the postoperative period, and 3) patient-related factors (age, life degree of autonomy, other comorbidities, surgery-related factors, and anesthesia method). In the patients in the disease stage I or II, anesthesia management is relatively safe. On the other hand, the patients in the disease stage IV have no surgical indication except life-saving emergent situation. In another words, anesthesiologists are required to make the judgment for the anesthesia management of the patient in the disease stage III, based on the assessment of patient-related factors, surgery-related factors, and prognosis.

    Full Text Available Background: Appropriate and timely care seeking reduces mortality for childhood illnesses including pneumonia. Despite over 90 000 Lady Health Workers (LHWs deployed in Pakistan, whose tasks included management of pneumonia, only 16% of care takers sought care from them for respiratory infections. As part of a community case management trial for childhood pneumonia, community mobilization interventions were implemented to improve care seeking from LHWs in Haripur district, Pakistan. The objective of the study was to increase the number of children receiving treatment for pneumonia and severe pneumonia by Lady Health Workers (LHWs through community mobilization approaches for prompt recognition and care seeking in 2 to 59 month–old children. Methods: To assess pneumonia care seeking practices, pre and post– intervention household surveys were conducted in 28 target Union Councils. Formative research to improve existing LHW training materials, job aids and other materials was carried out. Advocacy events were organized, LHWs and male health promoters were trained in community mobilization, non–functional women and male health committees were revitalized and LHWs and male health promoters conducted community awareness sessions. Results: The community mobilization interventions were implemented from April 2008 – December 2009. Project and LHW program staff organized 113 sensitization meetings for opinion leaders, which were attended by 2262 males and 3288 females. The 511 trained LHWs organized 6132 community awareness sessions attended by 50 056 women and 511 male promoters conducted 523 sessions attended by 7845 males. In one year period, the number of LHWs treating pneumonia increased from 11 in April 2008 to 505 in March 2009. The care seeking from LHWs for suspected pneumonia increased from 0.7% in pre–intervention survey to 49.2% in post–intervention survey. Conclusion: The increase in care seeking from LHWs benefited the community

    A 63-year-old Dutch man became colonized with a carbapenem resistant Klebsiella pneumoniae during a period of hospitalization in India. His recovery in the Netherlands was complicated by pneumonia due to this difficult-to-control multiresistant bacteria to which he eventually succumbed. Carbapenem resistance in Enterobacteriaceae, such as K. pneumoniae, is usually caused by carbapenemase (a betalactamase) production. Carbapenemase producing Enterobacteriaceae (CPE) are spreading throughout the world and cause difficult-to-treat infections that are associated with high mortality. This case report illustrates the clinical challenges associated with infection with these multiresistant Enterobacteriaceae. In the Netherlands, there are no guidelines for detection of CPE and carbapenemase production can frequently go undetected in clinical microbiology laboratories. As a consequence, adequate treatment of CPE infections and infection control measures to prevent the spread of CPE can be delayed. Expeditious development and implementation of existing Dutch draft guidelines for detection methods of CPE is therefore warranted.

    The association of inhaled corticosteroids (ICS) and pneumonia in patients with chronic obstructive pulmonary disease (COPD) is still controversial.From the National Health Insurance Database of Taiwan, COPD cases with history of acute exacerbation (AE) were identified (COPD cohort). Time-dependent Cox regression analysis was applied to investigate the risk factors for pneumonia with COPD severity controlled by surrogate variables. Among the COPD cohort, those who continuously used ICS for more than 360 days without interruption were selected (ICS cohort). The incidence rate of pneumonia during ICS use was compared with those before ICS use and after ICS discontinuation by using pair t test.A total of 6034 and 842 cases were identified as the COPD and ICS cohorts, respectively. In the COPD cohort, recent ICS use was independently associated with pneumonia (hazard ratio: 1.06 [1.02-1.11] for per 80 mg of budesonide). Other independent risk factors included age, male, diabetes mellitus, malignancy, low income, baseline pneumonia event, and recent use of oral corticosteroids and aminophylline. In the ICS cohort, while AE rate gradually decreased, the incidence rate of pneumonia significantly increased after ICS use (from 0.10 to 0.21 event/person-year, P = 0.001).This study demonstrates the association between ICS use and pneumonia in patients with COPD and history of AE. ICS should be judiciously used in indicated COPD patients.

    In France, cancer hits around 1700 children (0-14 years) each year. The age-standardized incidence rate for all cancers combined is 152 cases per million children per year, with a sex ratio of 1.2. In other terms, one child out of 440 develops a cancer before the age of 15 in industrial countries. The most frequent cancers were leukaemia (29%), embryonal tumours apart central nervous system (25%), central nervous system tumour (23%) and lymphoma (12%). The incidence varies between countries with higher overall rates in industrialized countries. These variations may reflect differences in diagnostic techniques or registration or in the distribution of possible risk factors. Five-year survival after childhood cancer has dramatically improved in the last 30 years, reaching yet 80%.

    2015-01-01

    Zinc is an essential micronutrient important for growth and for normal function of the immune system. Many children in developing countries have inadequate zinc nutrition. Routine zinc supplementation reduces the risk of respiratory infections and diarrhea, the two leading causes of morbidity and mortality in young children worldwide. In childhood diarrhea oral zinc also reduces illness duration and risk of persistent episodes. Oral zinc is therefore recommended for the treatment of acute diarrhea in young children. The results from the studies that have measured the therapeutic effect of zinc on acute respiratory infections, however, are conflicting. Moreover, the results of therapeutic zinc for childhood malaria also are so far not promising.This paper gives a brief outline of the current evidence from clinical trials on therapeutic effect of oral zinc on childhood respiratory infections, pneumonia and malaria and also of new evidence of the effect on serious bacterial illness in young infants.

    Full Text Available Las infecciones por Streptococcus pneumoniae son frecuentes en la población pediátrica especialmente en los niños menores de 2 años. El S. pneumoniae puede producir infecciones invasoras con una alta tasa de mortalidad y morbilidad como lo son las meningitis bacterianas, la neumonía y bacteremias siendo a la vez el agente que con mayor frecuencia se detecta en el oído medio de niños con otitis media. En la actualidad existe una vacuna conjugada contra esta bacteria que protege contra los siete serotipos de S. pneumoniae más frecuentes en el mundo y que a su vez son los mismos serotipos que presentan una mayor incidencia de resistencia a los antibioticos de uso frecuente. La vacuna no solo protege contra este tipo de infecciones sino que se ha demostrado que disminuye la colonización nasofaringea de los niños que han recibido la vacuna produciendo a su vez, una reducción en el numero de infecciones, por esta bacteria, en poblaciones de personas mayores de 5 años, incluyendo adultos y personas mayores a los 65 años (efecto rebaño. Con base en los serotipos aislados en niños costarricenses con otitis media, se puede calcular que la cobertura de esta vacuna en Costa Rica sería de aproximadamente un 74% e incluyendo mayoritariamente, los serotipos que presentan resistencia antimicrobriana más frecuentemente.The heptavalent S. pneumoniae conjugate vaccine has shown to be safe and effective in preventing pediatric invasive infections and otitis media caused by S. pneumoniae. The routine use of these vaccines has dramatically reduced the incidence of invasive pneumococcal diseases in children younger than 2 years old and because of a reduction in colonization of the children’s nasopharynx, the transmission from child to adult has been reduced and the number of secondary S. pneumoniae infections in adults. Another benefit of the routine use of this vaccine has been the reduction of vaccine-type antimicrobial resistant strains. Based on

    Pneumonia, the inflammatory state of lung tissue primarily due to microbial infection, claimed 52,306 lives in the United States in 2007 (1) and resulted in the hospitalization of 1.1 million patients (2). With an average length of in-patient hospital stay of five days (2), pneumonia and influenza comprise significant financial burden costing the United States $40.2 billion in 2005 (3). Under the current Infectious Disease Society of America/American Thoracic Society guidelines, standard-of-care recommendations include the rapid administration of an appropriate antibiotic regiment, fluid replacement, and ventilation (if necessary). Non-standard therapies include the use of corticosteroids and statins; however, these therapies lack conclusive supporting evidence (4). (Figure 1) Osteopathic Manipulative Treatment (OMT) is a cost-effective adjunctive treatment of pneumonia that has been shown to reduce patients' length of hospital stay, duration of intravenous antibiotics, and incidence of respiratory failure or death when compared to subjects who received conventional care alone (5). The use of manual manipulation techniques for pneumonia was first recorded as early as the Spanish influenza pandemic of 1918, when patients treated with standard medical care had an estimated mortality rate of 33%, compared to a 10% mortality rate in patients treated by osteopathic physicians (6). When applied to the management of pneumonia, manual manipulation techniques bolster lymphatic flow, respiratory function, and immunological defense by targeting anatomical structures involved in the these systems(7,8, 9, 10). The objective of this review video-article is three-fold: a) summarize the findings of randomized controlled studies on the efficacy of OMT in adult patients with diagnosed pneumonia, b) demonstrate established protocols utilized by osteopathic physicians treating pneumonia, c) elucidate the physiological mechanisms behind manual manipulation of the respiratory and

    Over the last decades many epidemiologic studies considered the morbidity patterns for respiratory diseases and lung function of children in the context of ambient air pollution usually measured in the postnatal period. The main purpose of this study is to assess the impact of prenatal exposure to fine particulate matter (PM2.5) on the recurrent broncho-pulmonary infections in early childhood. The study included 214 children who had measurements of personal prenatal PM2.5 exposure and regularly collected data on the occurrence of acute bronchitis and pneumonia diagnosed by a physician from birth over the seven-year follow-up. The effect of prenatal exposure to PM2.5 was adjusted in the multivariable logistic models for potential confounders, such as prenatal and postnatal ETS (environmental tobacco smoke), city residence area as a proxy of postnatal urban exposure, children's sensitization to domestic aeroallergens, and asthma. In the subgroup of children with available PM2.5 indoor levels, the effect of prenatal exposure was additionally adjusted for indoor exposure as well. The adjusted odds ratio (OR) for incidence of recurrent broncho-pulmonary infections (five or more spells of bronchitis and/or pneumonia) recorded in the follow-up significantly correlated in a dose-response manner with the prenatal PM2.5 level (OR=2.44, 95%CI: 1.12-5.36). In conclusion, the study suggests that prenatal exposure to PM2.5 increases susceptibility to respiratory infections and may program respiratory morbidity in early childhood. The study also provides evidence that the target value of 20μg/m(3) for the 24-h mean level of PM2.5 protects unborn babies better than earlier established EPA guidelines.

Chest computed tomography revealed bilateral ground-glass opacity, and bronchoalveolar lavage fluid showed increased eosinophils. Two episodes of transient eosinophilia in peripheral blood were observed after serial administration of anticancer drugs before the admission, and drug-induced lymphocyte stimulation test to cisplatin was positive. Thus cisplatin-induced eosinophilic pneumonia was suspected, and corticosteroid was effectively administered. To our knowledge, this is the first reported case of cisplatin-induced eosinophilic pneumonia.

    Enterobacter species have increasingly been identified as pathogens over the past several decades. These bacterial species have become more important because most are resistant to cephalothin and cefoxitin, and can produce extended-spectrum {beta}-lactamase. Enterobacter asburiae (E. asburiae) is a gram-negative rod of the family Enterobacteriaceae, named in 1986. Since then, there has been only one clinical report of E. asburiae pneumonia. We report a case of E. asburiae pneumonia with cavitation and compare it with the previous case.

    Full Text Available Acute respiratory tract infections may trigger acute asthma attacks and may be held responsible for etiopathogenesis in children with asthma. Although bacterial infections attract a limited amount of attention, recently Chlamydia pneumoniae (CP and Mycoplasma pneumoniae (MP, in particular, are reported to be the possible factors. IgM and IgG seroprevalence was investigated in 66 children patients with bronchial asthma (between the ages of 3 and 14 for CP and Mycoplasma pneumoniae. In a total of 66 cases, 18 (27.2% patients were detected with IgG positivity for CP whereas 27 of them (40.9% were detected with IgG positivity for MP. IgG positivity was determined in 6 patients (13.0% in the control group for CP, and in 6 patients (10.8% in the control group for MP. The rate of the asthma patients with IgG seropositivity for MP was 4 times higher than that of the control group. It was seen that IgG antibody seropositivity for CP was higher in those with more frequent attacks. No such difference was observed in terms of IgG antibody seropositivity for M. pneumoniae. There are many studies indicating that CP and MP infections take an importance place in the etiology of bronchial asthma and asthma attacks in children. The results obtained reveal the effect of both microorganisms on the etiopathogenesis of the bronchial asthma and the increased number of asthma attacks.

    Full Text Available Land and forest fires is a familiar phenomenon in some parts of Indonesia, particularly Sumatera and Kalimantan Island. This phenomenon developes into a form of disasters that has an impact on people's life. Catastrophic events smoke caused by forest fires happened several times in Indonesia. Smoke could influence very negative impact on public health such as Acute Respiratory Infection (ARI and pneumonia. The purpose of research conducted in 2011 was to analyse the impact of forest fires on the incidence of ARI and pneumonia in Pulang Pisau, Central Kalimantan. Using a cross-sectional study design, data analysis was done descriptively, to describe the trend of ARI and pneumonia during 2004-2011 in the district. The results showed that in Pulang Pisau District for seven years (2004-2011, the incidence of ARI was fluctuated in each year, but the highest in December, such as in 2005 and 2008 the incidence of ARI reached 21,65 per 1000 population and 35,58 per 1000 population respectively. The incidence of pneumonia among ≤ 5 years old varied, the highest incidence in 2004 occurred  in March (0,35, 2006 in July (0,51, 2007 in March (0,55 and 2008 in January (0,42 respectively.  The highest hotspot in 2004 occurred in October (962, 2005 in September (270 and 2011 in August (316 respectively. As a conclusion, the impact of smoke from forest fires on health could be respiratory infection especially for high risk groups. Probably, there was a relationship of ARI and pneumonia with quality of the air in the study area.

  8. Childhood asthma and risk factors

    2010-01-01

    Full Text Available Introduction. This article summarizes the contribution of epidemiology to the understanding of childhood asthma. The first task in epidemiology is to determine prevalence and incidence of any disease. Prevalence. Epidemiological investigations are aimed at evaluating hypotheses about causes of disease by defining demographic characteristics of a certain population as well as by determining possible effects of environmental factors. In spite of some limitations, data obtained by epidemiological investigations have been valuable in confirming both the increasing incidence of asthma and the differences in prevalence in certain population groups. The observance of this phenomenon has led to much speculation and a lot of attempts to identify the reasons behind the rising prevalence. Risk factors. Epidemiological studies have identified risk factors for the development of childhood asthma and provided insight into natural history of disease and prognosis. Factors ranging from increased numbers of immunizations to increased air pollution have been suggested, but subsequent analysis has failed to provide the supporting evidence to implicate most of these possibilities. The concept known as the hygiene hypothesis has gained some support from epidemiological studies. Conclusion. The development of asthma as well as its severity are affected by numerous factors and their interactions can be explained by the heterogeneous nature of this disease.

    Full Text Available BACKGROUND Knowledge of the incidence of ventilator-associated pneumonia (VAP and its associated risk factors is imperative for the development and use of more effective preventive measures. METHODOLOGY We conducted a prospective cohort study over a period of 12 months to determine the incidence and the risk factors for development of VAP in critically ill adult patients admitted in intensive care units (ICUs in Chalmeda Anand Rao Institute of Medical Sciences, Karimnagar, we included 150 patients, on mechanical ventilation for more than 48 hours. VAP was diagnosed according to the current diagnostic criteria. RESULTS The study cohort comprised of 150 patients of various cases of cerebrovascular accident, poisoning, neurological disorders, sepsis and others. VAP was diagnosed when a score of ≥6 was obtained in the clinical pulmonary infection scoring system having six variables and a maximum score of 12. The mean age of the patients was 40 years. Of the 150 patients, 28 patients developed VAP during the ICU stay. The incidence of VAP in our study was 18.8%. The risk factor in our study was decrease in the PaO2/FiO2 ratio, duration of mechanical ventilation, impaired consciousness, tracheostomy, re-intubation, emergency intubation, nasogastric tube, emergency intubation and intravenous sedatives were found to be the specific risk factors for early onset VAP, while tracheostomy and re-intubation were the independent predictors of late-onset VAP, The most predominant organisms in our study was Pseudomonas (39.2%. CONCLUSIONS Knowledge of these risk factors may be useful in implementing simple and effective preventive measures. Precaution during emergency intubation, minimizing the occurrence of reintubation, avoidance of tracheostomy as far as possible, and minimization of sedation. The ICU clinicians should be aware of the risk factors for VAP, which could prove useful in identifying patients at high risk for VAP, and modifying patient care to

    Aim of this study was to determine the incidence and molecular epidemiology of carbapenemase-producing Escherichia coli and Klebsiella pneumoniae in Germany. E. coli and K. pneumoniae isolates from clinical samples which were non-susceptible to carbapenems were collected in laboratories serving 20 hospitals throughout Germany from November 2013 to April 2014. The isolates were tested for the presence of carbapenemases by PCR and phenotypic methods and typed by multilocus sequence typing. Risk factors including a previous hospitalization abroad were analysed. Carbapenemases were detected in 24 isolates from 22 patients out of 464,514 admissions. Carbapenemases included OXA-48 (n=14), KPC-2 (n=8) and NDM-1 (n=2). Except for two K. pneumoniae isolates with ST101, all OXA-48 producing strains belonged to different clones. In contrast, half of KPC-2 producing K. pneumoniae were of ST258 and both NDM-1 producing strains were of ST11. Compared to carbapenem-susceptible controls, patients with carbapenemase-producing strains differed by a significantly higher proportion of males, a higher proportion of isolates from wound samples and a more frequent previous stay abroad in univariate analysis. This multicentre study demonstrated an incidence of carbapenemase-producing E. coli and K. pneumoniae from clinical samples in Germany of 0.047 cases per 1000 admissions. OXA-48 was more frequent than KPC-2 and NDM-1 and showed a multiclonal background.

    Galván, José María; Rajas, Olga; Aspa, Javier

    2015-11-01

    Although bacteria are the main pathogens involved in community-acquired pneumonia, a significant number of community-acquired pneumonia are caused by viruses, either directly or as part of a co-infection. The clinical picture of these different pneumonias can be very similar, but viral infection is more common in the pediatric and geriatric populations, leukocytes are not generally elevated, fever is variable, and upper respiratory tract symptoms often occur; procalcitonin levels are not generally affected. For years, the diagnosis of viral pneumonia was based on cell culture and antigen detection, but since the introduction of polymerase chain reaction techniques in the clinical setting, identification of these pathogens has increased and new microorganisms such as human bocavirus have been discovered. In general, influenza virus type A and syncytial respiratory virus are still the main pathogens involved in this entity. However, in recent years, outbreaks of deadly coronavirus and zoonotic influenza virus have demonstrated the need for constant alert in the face of new emerging pathogens. Neuraminidase inhibitors for viral pneumonia have been shown to reduce transmission in cases of exposure and to improve the clinical progress of patients in intensive care; their use in common infections is not recommended. Ribavirin has been used in children with syncytial respiratory virus, and in immunosuppressed subjects. Apart from these drugs, no antiviral has been shown to be effective. Prevention with anti-influenza virus vaccination and with monoclonal antibodies, in the case of syncytial respiratory virus, may reduce the incidence of pneumonia.

    Community-acquired pneumonia is common in the elderly person; its presentation in this population is often confounded by multiple comorbid illnesses, including those that result in confusion. Although severity-of-illness scoring systems might aid decision-making, clinical judgment following a careful assessment is key in deciding on the site of care and appropriate therapy.

    2006-07-01

    Full Text Available Abstract Background Anemic syndrome is a frequent problem in intensive care units. The most probable etiology is the suppression of the erythropoietin response due to the direct effects of cytokines, as well as frequent blood sampling. Transfusions are not free of complications, therefore transfusion reactions are estimated to occur in 2% of the total packed red blood cells (pRBCs transfused. In the past several years, several trials had tried to compare the restrictive with the more liberal use of transfusions, and they were found to be equally effective. Nosocomial pneumonia is the most common nosocomial infection in intensive care units; the prevalence is 47% with an attributive mortality of 33%. There are multiple risk factors for the development of nosocomial pneumonia. Colonization of the upper airways is the most important pathophysiological factor but there are other factors implicated like, sedation techniques, inappropriate use of antibiotics and recumbent positioning. A secondary analysis of the CRIT study describes transfusion therapy and its practices in the United States. They found that transfusion practice is an independent risk factor for the development of nosocomial pneumonia. Methods This is a multicenter, prospective cohort study in different intensive care units in Colombia. A total of 474 patients were selected who had more than 48 hours of mechanical ventilation. The primary objective is to try to demonstrate the hypothetical relationship between the use of transfusions and nosocomial pneumonia. Secondly, we will try to determine which other factors are implicated in the development of pneumonia in intensive care units and describe the incidence of pneumonia and transfusion practices. Discussion Ventilator associated pneumonia is a primary problem in the intensive care unit, multiple factors have been associated with its presence in this study we try to explore the possible association between pneumonia and transfusion

    2008-01-01

    The pattern of infections in the first years of life modulates our immune system, and a low incidence of infections has been linked to an increased risk of common childhood acute lymphoblastic leukemia (ALL). We here present a new interpretation of these observations--the adrenal hypothesis......--that proposes that the risk of childhood ALL is reduced when early childhood infections induce qualitative and quantitative changes in the hypothalamus-pituitary-adrenal axis that increase plasma cortisol levels. This may directly eliminate leukemic cells as well as preleukemic cells for the ALL subsets...

    We describe a 10 year old boy with organising pneumonia associated with acute Mycoplasma pneumoniae infection. The diagnosis of organising pneumonia was made by open lung biopsy and the M pneumoniae infection was proven serologically. Antibiotic and long term corticosteroid treatment resulted in steadily improving pulmonary function monitored by spirometry. The introduction of anti-inflammatory treatment with NSAIDs/immunosuppressive agents in order to spare steroids was well tolerated and resulted in further improvement of the pulmonary function. To our knowledge this is the first documented case of Mycoplasma pneumoniae associated organising pneumonia to be reported in a child.

  20. Novel clones of Streptococcus pneumoniae causing invasive disease in Malaysia.

    Johanna M Jefferies

    Full Text Available Although Streptococcus pneumoniae is a leading cause of childhood disease in South East Asia, little has previously been reported regarding the epidemiology of invasive pneumococcal disease in Malaysia and very few studies have explored pneumococcal epidemiology using multilocus sequence typing (MLST. Here we describe serotype, multilocus sequence type (ST, and penicillin susceptibility of thirty pneumococcal invasive disease isolates received by the University of Malaya Medical Centre between February 2000 and January 2007 and relate this to the serotypes included in current pneumococcal conjugate vaccines. A high level of diversity was observed; fourteen serotypes and 26 sequence types (ST, (11 of which were not previously described were detected from 30 isolates. Penicillin non-susceptible pneumococci accounted for 33% of isolates. The extent of molecular heterogeneity within carried and disease-causing Malaysian pneumococci remains unknown. Larger surveillance and epidemiological studies are now required in this region to provide robust evidence on which to base future vaccine policy.

  1. Cardiac complications associated with short-term mortality in schizophrenia patients hospitalized for pneumonia: a nationwide case-control study.

    Directory of Open Access Journals (Sweden)

    Ya-Tang Liao

    Full Text Available BACKGROUND: Pneumonia is one of most prevalent infectious diseases worldwide and is associated with considerable mortality. In comparison to general population, schizophrenia patients hospitalized for pneumonia have poorer outcomes. We explored the risk factors of short-term mortality in this population because the information is lacking in the literature. METHODS: In a nationwide schizophrenia cohort, derived from the National Health Insurance Research Database in Taiwan, that was hospitalized for pneumonia between 2000 and 2008 (n = 1,741, we identified 141 subjects who died during their hospitalizations or shortly after their discharges. Based on risk-set sampling in a 1∶4 ratio, 468 matched controls were selected from the study cohort (i.e., schizophrenia cohort with pneumonia. Physical illnesses were categorized as pre-existing and incident illnesses that developed after pneumonia respectively. Exposures to medications were categorized by type, duration, and defined daily dose. We used stepwise conditional logistic regression to explore the risk factors for short-term mortality. RESULTS: Pre-existing arrhythmia was associated with short-term mortality (adjusted risk ratio [RR] = 4.99, p<0.01. Several variables during hospitalization were associated with increased mortality risk, including incident arrhythmia (RR = 7.44, p<0.01, incident heart failure (RR = 5.49, p = 0.0183 and the use of hypoglycemic drugs (RR = 2.32, p<0.01. Furthermore, individual antipsychotic drugs (such as clozapine known to induce pneumonia were not significantly associated with the risk. CONCLUSIONS: Incident cardiac complications following pneumonia are associated with increased short-term mortality. These findings have broad implications for clinical intervention and future studies are needed to clarify the mechanisms of the risk factors.

    Klebsiella pneumoniae is an important cause of community-onset pneumonia in Asian countries and South Africa. We investigated the clinical characteristics of K. pneumoniae causing community-onset pneumonia, and the associated microbiological features between K. pneumoniae isolates from pneumonia and those from the nasopharynx in Taiwan. This study was conducted at the Taipei Veterans General Hospital during July, 2012 to February, 2014. The clinical characteristics in patients with community-onset K. pneumoniae pneumonia were analyzed. K. pneumoniae isolates from the nasopharynx of adults attending otorhinolaryngology outpatient clinics were collected to compare their microbiological features with those from pneumonia. Capsular genotypes, antimicrobial susceptibility, and multilocus sequence type (MLST) were determined among these strains. Ninety-one patients with community-onset K. pneumoniae pneumonia were enrolled. We found a high mortality (29.7%) among these patients. Capsular types K1, K2, K5, K20, K54, and K57 accounted for ∼70% of the K. pneumoniae isolates causing pneumonia, and ∼70% of all the K. pneumoniae strains isolated from the nasopharynx of patients in outpatient clinics. The MLST profiles further demonstrated the genetic relatedness between most pneumonia isolates and those from the nasopharynx. In conclusion, our results show that community-onset pneumonia caused by K. pneumoniae was associated with high mortality and could have a reservoir in the nasopharynx. To tackle this high-mortality disease, the distribution of capsular types in the nasopharynx might have implications for future vaccine development.

    File, T M

    2006-05-01

    Streptococcus pneumoniae is the leading bacterial cause of community-acquired respiratory tract infections. Prior to the 1970s this pathogen was uniformly susceptible to penicillin and most other antimicrobials. However, since the 1990s there has been a significant increase in drug-resistant Streptococcus pneumoniae (DRSP) due, in large part, to increased use of antimicrobials. The clinical significance of this resistance is not definitely established, but appears to be most relevant to specific MICs for specific antimicrobials. Certain beta-lactams (amoxicillin, cefotaxime, ceftriaxone), the respiratory fluoroquinolones, and telithromycin are among several agents that remain effective against DRSP. Continued surveillance studies, appropriate antimicrobial usage campaigns, stratification of patients based on known risk factors for resistance, and vaccination programmes are needed to appropriately manage DRSP and limit its spread.

    2005-02-01

    Approximately 10% of all hospital admissions are complicated by critical incidents in which harm is caused to the patient - this amounts to more than 850,000 incidents annually. Critical incident reporting (CIR) systems refer to the structured reporting, collation and analysis of such incidents. This article describes the attributes required for an effective CIR system. Example neonatal trigger events and a management pathway for handling a critical incident report are described. The benefits and limitations of CIR systems, reactive and prospective approaches to the analysis of actual or potential critical incidents and the assessment of risk are also reviewed. Individual human error is but one contributor in the majority of critical incidents. Recognition of this and the fostering of an organisational culture that views critical incident reports as an opportunity to learn and to improve future patient care is vital if CIR systems are to be effective.

    Full Text Available Abstract Background An increased incidence of pneumonia in patients with chronic obstructive pulmonary disease (COPD under inhaled corticosteroid (ICS therapy was noticed in previous studies. We performed a prospective study to elucidate the risk factors for the development of pneumonia in this group of patients. Methods A prospective, non-randomized study with patients diagnosed as having COPD from 2007 to 2008 identified in the Far Eastern Memorial Hospital were recruited. We recorded data for all patients, including clinical features and signs, demographic data, lung function status, and medications. Bio-markers such as C-reactive protein (CRP and placenta growth factor (PlGF were checked at first diagnosis. Every acute exacerbation was also recorded, especially pneumonia events, which were confirmed by chest radiography. Multivariate analysis was performed with stepwise logistic regression for pneumonia risk factors. Results 274 patients were diagnosed as having COPD during the study period and 29 patients suffered from pneumonia with a prevalence of 10.6%. The rate was significantly higher in patients with ICS therapy (20/125, 16% compared with those without ICS (9/149, 6% (p = 0.02. We stratified ICS therapy into medium dose (500-999 ug/day fluticasone equivalent, 71 patients and high dose (1000 ug/day and higher fluticasone equivalent, 54 patients group. There was no statistical difference in the incidence of pneumonia between these two group (medium dose: 13/71, 18.3% vs. high dose: 7/54, 12.9%, p = 0.47. Multivariate analysis was performed to identify the risk factors for developing pneumonia and included forced expiratory volume in one second (FEV1 less than 40% of predicted (odds ratio (OR 2.2, 95% confidence interval (CI: 1.1-6.9, ICS prescription ((OR 2.4, 95% (CI: 1.3-8.7, the presence of diabetes mellitus (DM (OR 2.6, 95% CI: 1.2-9.4 and PlGF level over 40 pg/L (OR 4.1, 95% CI: 1.5-9.9.

    2015-07-01

    A 4-month-old boy with past medical history of eczema presented with fever and cough; a chest radiograph showed lung consolidation, and he was initially treated with amoxicillin for presumed community-acquired pneumonia. After several days, his fever persisted. He was also profoundly anemic. Antibiotic coverage was broadened because of the concern for resistant organisms; he began to improve and was discharged from the hospital. However, at 5 months of age, his fever returned, and he continued to demonstrate lung consolidation on chest radiograph. Additionally, he had lost weight and continued to be anemic. Splenic cysts were noted on abdominal ultrasound. He was diagnosed with an unusual etiology for his pneumonia and improved with the appropriate therapy. An underlying immunodeficiency was suspected, but initial testing was nondiagnostic. At 12 months of age, he presented with another infection, and the final diagnosis was made.

    Pneumonia is a major cause of morbidity and mortality leading to a high rate of hospitalization especially in theelderly. It is often a sign of frailty and is associated with a poor prognosis. However, taking into account the geriatric specificities (risk factors, atypical clinical presentations with "geriatric syndromes", ethical debate) using an interdisciplinary and a comprehensive geriatric approach remains an important responsibility of the general practitionner. This article summarizes these specificities and offers interventions targeted on the characteristics of elderly patients.

    Full Text Available BACKGROUND: Epilepsy is one of the most common neurologic disorders of childhood, affecting about 0.4-0.8% of all children up to the age of 20. METHODOLOGY: A population-based retrospective cohort study. Aim was to determine incidence and identify perinatal and reproductive risk factors of epilepsy in children born between 1989 and 2008 among women (n = 43,389 delivered in Kuopio University Hospital. Risk factors of childhood epilepsy were determined by using logistic regression analysis. PRINCIPAL FINDINGS: The incidence of childhood epilepsy was 0.7% (n = 302 of 43,389. Maternal epilepsy, major congenital anomalies and use of assisted reproductive technology (ART were associated with 4.25-, 3.61-, and 1.67- fold increased incidence of childhood epilepsy. A 10 cm increase in umbilical cord length was associated with a 15% decrease in the incidence of epilepsy (adjusted OR 0.85, 95% CI 0.78-0.94. However, the above reproductive factors accounted for less than 2% of total incidence, whereas maternal epilepsy proved to be the highest risk factor. CONCLUSIONS: Perinatal and reproductive factors were shown to be minor risk factors of childhood epilepsy, implying that little can be done in obstetric care to prevent childhood epilepsy. Infertility treatment and umbilical cord length, independent of gestational age and congenital malformations, may be novel markers of childhood epilepsy.

    Purpose Patients with nursing home-acquired pneumonia (NHAP) should be treated as hospital-acquired pneumonia (HAP) according to guidelines published in 2005. However, controversy still exists on whether the high mortality of NHAP results from multidrug resistant pathogens or underlying disease. We aimed to outline differences and factors contributing to mortality between NHAP and community-acquired pneumonia (CAP) patients. Materials and Methods We retrospectively evaluated patients aged 65 years or older with either CAP or NHAP from 2008 to 2014. Patients with healthcare-associated pneumonia other than NHAP or HAP were excluded. Results Among 317 patients, 212 patients had CAP and 105 had NHAP. Patients with NHAP had higher mortality, more frequently used a ventilator, and had disease of higher severity than CAP. The incidences of aspiration, tube feeding, and poor functional status were higher in NHAP. Twenty three out of 54 NHAP patients and three out of 62 CAP patients had multidrug resistant pathogens (p<0.001). Eleven patients with NHAP died at discharge, compared to 7 patients with CAP (p=0.009). However, there was no association between mortality rate and presence of multidrug-resistant pathogens. The number of involved lobes on chest X-ray [odds ratio (OR)=1.708; 95% confidence interval (CI), 1.120 to 2.605] and use of mechanical ventilation (OR=9.537; 95% CI, 1.635 to 55.632) were significantly associated with in-hospital mortality. Conclusion Patients with NHAP had higher mortality than patients with CAP. The excess mortality among patients with NHAP and CAP was related to disease severity but not to the presence of multidrug resistant pathogens. PMID:27873512

    Full Text Available Mycoplasma pneumonia is common agent causing community acquired pneumonia in younger population. However, the course of illness is usually benign and is rarely associated with pulmonary complications. We report a 27 years old female patient with unilateral pneumonia followed by pleural effusion and adhesions on the same side. This potential source of infection should be considered in young patients where resolution of symptoms from pneumonia is delayed.

    Organ cultures of adult hamster trachea were used to evaluate the cytotoxic potential of cell fractions of Mycoplasma pneumoniae. Cytoplasm was essentially devoid of activity, whereas viable cells and membrane preparations, at a level of 25 μg of protein per ml, induced necrosis. Damage, as revealed by light and electron microscopy, included ciliostasis, vacuolization, loss of ciliated respiratory epithelial cells, disorganization, and a loss of polarity. Dose response data indicated that the speed and degree of cytotoxicity was directly related to the concentration of membranes. Doses of 30 to 60 μg of protein per ml could reduce relative ciliary activity to 20% of the control level within 4 days. Membranes prepared after freeze-thaw lysis of cells were almost twice as active as those isolated after a combination of osmotic and sonic shock. Membranes of M. fermentans were inactive, though both the FH and M129 strains of M. pneumoniae were toxic. These data indicate that the toxic factor responsible for M. pneumoniae may be located in the cell membrane. Images PMID:16558100

    Full Text Available AIMS: To determine the incidence, risk factors, mortality and organisms causing nosocomial pneumonia (NP in intubated patients in Paediatric Intensive Care Unit (PICU. MATERIALS & METHODS: All patients with endotracheal (ET tube with or without mechanical ventilation (MV in a PICU of a tertiary care teaching hospital were included in this prospective study. Clinical parameters and investigations were evaluated in patients who developed nosocomial pneumonia (NP. Colonisation of the ET tube tip was studied by culture and the antibiotic susceptibility pattern of the isolates was determined. RESULTS: Sixty-nine patients had an ET tube inserted and fifty-nine of these underwent MV. ET tube tip colonisation was seen in 70 out of 88 ET tubes inserted. The incidence of NP in patients with ET tube was 27.54% (7.96/100 days of ET intubation. NP developed only in patients undergoing MV. The main risk factors for developing NP were - duration of MV and duration of stay in the PICU. Age, sex, immunocompromised status and altered sensorium did not increase the risk of NP. The mortality in cases with NP was 47. 37%. E. coli and Klebsiella were the commonest organisms isolated from the ET tube tip cultures with maximum susceptibility to amikacin and cefotaxime. CONCLUSIONS: NP developed only in patients undergoing MV. Duration of MV and duration of stay in the PICU increased the risk of developing NP.

    Klebsiella species is the second most commonly isolated gram-negative organism in sepsis and a frequent causative pathogen in pneumonia. The receptor for advanced glycation end products (RAGE) is expressed on different cell types and plays a key role in diverse inflammatory responses. We here aimed to investigate the role of RAGE in the host response to Klebsiella (K.) pneumoniae pneumonia and intransally inoculated rage gene deficient (RAGE-/-) and normal wild-type (Wt) mice with K. pneumoniae. Klebsiella pneumonia resulted in an increased pulmonary expression of RAGE. Furthermore, the high-affinity RAGE ligand high mobility group box-1 was upregulated during K. pneumoniae pneumonia. RAGE deficiency impaired host defense as reflected by a worsened survival, increased bacterial outgrowth and dissemination in RAGE-/- mice. RAGE-/- neutrophils showed a diminished phagocytosing capacity of live K. pneumoniae in vitro. Relative to Wt mice, RAGE-/- mice demonstrated similar lung inflammation, and slightly elevated-if any-cytokine and chemokine levels and unchanged hepatocellular injury. In addition, RAGE-/- mice displayed an unaltered response to intranasally instilled Klebsiella lipopolysaccharide (LPS) with respect to pulmonary cell recruitment and local release of cytokines and chemokines. These data suggest that (endogenous) RAGE protects against K. pneumoniae pneumonia. Also, they demonstrate that RAGE contributes to an effective antibacterial defense during K. pneumoniae pneumonia, at least partly via its participation in the phagocytic properties of professional granulocytes. Additionally, our results indicate that RAGE is not essential for the induction of a local and systemic inflammatory response to either intact Klebsiella or Klebsiella LPS.

  1. Disorders of childhood growth and development: childhood obesity.

    Mendez, Robert; Grissom, Maureen

    2013-07-01

    The incidence of childhood obesity in the United States is estimated at 17%, or 12 million children ages 2 to 19 years. Obesity is a multifactorial condition with syndromic and nonsyndromic variants. Genetic, social, ethnic, endocrinologic, and behavioral issues are all potential etiologic factors. Preventive efforts should begin with monitoring from birth and include breastfeeding until age 6 months, avoiding juices, and promoting fruit and vegetable consumption and adequate exercise. Childhood obesity is diagnosed based on body mass index; a child is considered overweight at the 85th to 95th percentiles and obese at or above the 95th percentile. After obesity is diagnosed, testing should include blood pressure levels, fasting lipid profile, diabetes screening, and liver function tests. The physician should obtain a detailed history of the physical activity level and food intake and assess possible complications of obesity, including depression and hypertension, annually. Lifestyle interventions with family involvement are the mainstay of management, with pharmacotherapy or bariatric surgery considered for adolescents only if intensive lifestyle modifications have failed and in the presence of comorbidities. Intervention by multiple disciplines (ie, medicine, nutrition, psychology) is recommended, and family physicians are encouraged to become more involved in encouraging physical activity and improved nutrition for children.

    Few comprehensive studies have searched for viruses and bacteria in children with community-acquired pneumonia (CAP). We identified 76 children hospitalized for pneumonia. Induced sputum samples were analysed for 18 viruses by antigen detection and PCR, and for six bacteria by culture and PCR. Viruses were found in 72% of samples, bacteria in 91%, and both in 66%. Rhinovirus (30%), human bocavirus (18%) and human metapneumovirus (14%) were the most commonly detected viruses. Two viruses were found in 22% of samples and three in 8%. The most common bacteria found were Streptococcus pneumoniae (50%), Haemophilus influenzae (38%), and Moraxella catarrhalis (28%). Rhinovirus-S. pneumoniae was the most commonly found combination of virus and bacterium (16%). All six children with treatment failure had both viruses and bacteria detected in the sputum. Otherwise, we found no special clinical characteristics in those with mixed viral-bacterial detections. With modern molecular diagnostic techniques, there are high rates of both viral and bacterial identification in childhood CAP. The clinical significance of mixed viral-bacterial infections remains unclear, although we found a potential association between them and treatment failure.

    Objective: To investigate the effects of feeding safety instructions and dietary intervention on as-piration pneumonia in elderly patients with dysphagia. Methods: The study included 40 long-term hospitalized elderly patients with dysphagia who nee-ded oral intake. According to the voluntary and matching principle, participants were divided into the intervention group ( n=20) and control group ( n=20) . We formed a multi-disciplinary team including clinical nurses, rehabilitation therapists and nutritionists. Clinical nurses collaborated with nutritionists and rehabilitation therapists to carry out feeding management. The patients in the control group were fed with semi-solid food, thick liquid, a partial mushy diet and so on accord-ing to their swallowing situations and tastes or preferences. The patients in the intervention group were fed with an all mushy diet. Patients in both groups were able to eat foods on their own or with assistance. Results: After a three-month intervention, the incidence of aspiration pneumonia in both groups was decreased, and the difference was statistically significant ( P<0. 05) . In the control group, seven patients had aspiration pneumonia, including two cases who died after nasogastric feeding due to aggravated dysphagia. In the control group, seven patients had aspiration pneumonia, in-cluding two cases was given nasogastric feeding due to aggravated dysphagia and then one case died. In the intervention group, four patients had aspiration pneumonia. There was no dropouts in either group. Conclusions: Elderly patients with dysphagia require a multidisciplinary team to work closely with them to carry out feeding management. Nurses should conduct safety guidance for care cate-ring and encouraging patients to actively eat a mushy diet. The diet can reduce the incidence of as-piration pneumonia, maintain oral intake and improve the quality of life.

    Full Text Available Urticaria multiforme is a rare clinical and morphological subtype of acute urticaria in childhood. Clinical features include acute onset of blanchable, annular, polycyclic, erythematous wheals with dusky or ecchymotic centers (target lesion-like. Pruritus in nearly all and edema on the face, hand and foot in the majority of cases are seen. Urticaria multiforme known as a cutaneous hypersensitivity reaction can often be misdiagnosed as erythema multiforme and serum-sickness-like reaction. Although the majority of cases have been related with viral or bacterial infections and drug use, the exact etiopathogenesis of the disease is yet unclear. Association of Mycoplasma pneumoniae infection and urticaria multiforme have been reported in only two cases in the literature. In this article, a total of four cases diagnosed as urticaria multiforme two of whom had clinical and serological proof of Mycoplasma pneumoniae infection has been presented, and diagnostic criteria, differential diagnosis, etiopathogenesis and treatment of urticaria multiforme have been reviewed.

    Full Text Available BACKGROUND: MRSA remains a leading cause of hospital-acquired (HAP and healthcare-associated pneumonia (HCAP. We describe the epidemiology and outcome of MRSA pneumonia in Canadian hospitals, and identify factors contributing to mortality. METHODS: Prospective surveillance for MRSA pneumonia in adults was done for one year (2011 in 11 Canadian hospitals. Standard criteria for MRSA HAP, HCAP, ventilator-associated pneumonia (VAP, and community-acquired pneumonia (CAP were used to identify cases. MRSA isolates underwent antimicrobial susceptibility testing, and were characterized by pulsed-field gel electrophoresis (PFGE and Panton-Valentine leukocidin (PVL gene detection. The primary outcome was all-cause mortality at 30 days. A multivariable analysis was done to examine the association between various host and microbial factors and mortality. RESULTS: A total of 161 patients with MRSA pneumonia were identified: 90 (56% with HAP, 26 (16% HCAP, and 45 (28% CAP; 23 (14% patients had VAP. The mean (± SD incidence of MRSA HAP was 0.32 (± 0.26 per 10,000 patient-days, and of MRSA VAP was 0.30 (± 0.5 per 1,000 ventilator-days. The 30-day all-cause mortality was 28.0%. In multivariable analysis, variables associated with mortality were the presence of multiorgan failure (OR 8.1; 95% CI 2.5-26.0, and infection with an isolate with reduced susceptibility to vancomycin (OR 2.5, 95% CI 1.0-6.3. CONCLUSIONS: MRSA pneumonia is associated with significant mortality. Severity of disease at presentation, and infection caused by an isolate with elevated MIC to vancomcyin are associated with increased mortality. Additional studies are required to better understand the impact of host and microbial variables on outcome.

    Full Text Available Klebsiella pneumoniae is a major cause of nosocomial pneumonia, septicemia and urinary tract infections, especially in newborns, blood cancer patients, and other immunocompromised candidates. The control of K. pneumoniae is a complicated issue due to its tight pathogenesis. Immuno-prophylactic preparations, especially those directed toward the bacterium O-antigen, showed to be the most successful way to prevent the infection incidence. However, all previously proposed preparations were either of limited spectrum or non-maternal, and hence not targeting the main Klebsiella patients. Moreover, all preparations were directed only to prevent the respiratory diseases due to that pathogen. This article addresses the development of a method originally used to purify the non-capsular bacterial- endotoxins, as a new and easy method for vaccine production against K. pneumoniae. The application of this method was preceded by a biotechnological control of capsular polysaccharide production in K. pneumoniae. The new produced natural conjugate between the bacterial O-antigen and its outer membrane proteins was evaluated by physicochemical and immunological methods to investigate its purity, integrity, safety and immunogenicity. It showed to be pure, stable, safe for use, and able to elicit a protective immunoglobulin titer against different Klebsiella infections. This immune-response proved to be transferable to the offspring of the vaccinated experimental rabbits via placenta.

    The emergence of extensively drug-resistant (XDR) Klebsiella pneumoniae has become a major challenge worldwide. In this study, we characterized the phenotypes and genetic features of nine XDR K. pneumoniae isolates from an integrated hospital in Zhejiang province, China, from September to October 2014. These XDR K. pneumoniae possessed at least five resistance determinants which contribute to highly resistant to β-lactam, β-lactam/inhibitor combinations, aminoglycosides, quinolones, carbapenems, chloroamphenicol and fosfomycin. All isolates carried blaKPC-2, blaCTX-M-9, blaSHV-11 and rmtB, and several isolates also harboured blaTEM-1 and qnrS. Southern blot experiments confirmed that blaKPC-2, rmtB and blaCTX-M-9 were located on the same ~54.2 kb plasmid. Conjugative plasmids were obtained from all K. pneumoniae isolates, further proving the transferable characteristic of the resistance determinants. The OmpK36 sequences showed various deletions and insertions that indicated additional amino acid residues and a deleted phenotype of OmpK36. PFGE demonstrated that all the isolates belonged to the same genotype. Multilocus sequence typing was concordant with PFGE results and revealed that ST11 was the most predominant clone. Our study revealed a high incidence and endemic spread of XDR K. pneumoniae in the hospital. Thus, effective infection control measures should be adopted to monitor and control the spread of multidrug-resistant isolates.

    Purpose: To evaluate effects of radiation therapy, chemotherapy, cigarette smoking, and alcohol consumption on the risk of second primary salivary gland cancer (SGC) in the Childhood Cancer Survivor Study (CCSS). Methods and Materials: Standardized incidence ratios (SIR) and excess absolute risks (EAR) of SGC in the CCSS were calculated using incidence rates from Surveillance, Epidemiology, and End Results population-based cancer registries. Radiation dose to the salivary glands was estimated based on medical records. Poisson regression was used to assess risks with respect to radiation dose, chemotherapy, smoking, and alcohol consumption. Results: During the time period of the study, 23 cases of SGC were diagnosed among 14,135 childhood cancer survivors. The mean age at diagnosis of the first primary cancer was 8.3 years, and the mean age at SGC diagnosis was 24.8 years. The incidence of SGC was 39-fold higher in the cohort than in the general population (SIR = 39.4; 95% CI = 25.4-57.8). The EAR was 9.8 per 100,000 person-years. Risk increased linearly with radiation dose (excess relative risk = 0.36/Gy; 95% CI = 0.06-2.5) and remained elevated after 20 years. There was no significant trend of increasing risk with increasing dose of chemotherapeutic agents, pack-years of cigarette smoking, or alcohol intake. Conclusion: Although the cumulative incidence of SGC was low, childhood cancer survivors treated with radiation experienced significantly increased risk for at least 2 decades after exposure, and risk was positively associated with radiation dose. Results underscore the importance of long-term follow up of childhood cancer survivors for the development of new malignancies.

    Childhood brain tumors are the most common pediatric solid tumor and include several histologic subtypes. Although progress has been made in improving survival rates for some subtypes, understanding of risk factors for childhood brain tumors remains limited to a few genetic syndromes and ionizing radiation to the head and neck. In this report, we review descriptive and analytical epidemiology childhood brain tumor studies from the past decade and highlight priority areas for future epidemiology investigations and methodological work that is needed to advance our understanding of childhood brain tumor causes. Specifically, we summarize the results of a review of studies published since 2004 that have analyzed incidence and survival in different international regions and that have examined potential genetic, immune system, developmental and birth characteristics, and environmental risk factors.

Objective: Using claims databases as a research model of real-world diagnosis and treatment, to determine if the use and dose of inhaled corticosteroids (ICS among patients with newly diagnosed COPD are associated with increased risk of pneumonia. Patients and methods: This was a retrospective cohort analysis of patients diagnosed with COPD between January 01, 2006 and September 30, 2010, drawn from databases (years 2006–2010. Patients (aged ≥45 years were followed until first pneumonia diagnosis, end of benefit enrollment, or December 31, 2010, whichever was earliest. A Cox proportional hazard model was used to assess the association of ICS use and risk of pneumonia, controlling for baseline characteristics. Daily ICS use was classified into low, medium, and high doses (1 µg–499 µg, 500 µg–999 µg, and ≥1000 µg fluticasone equivalents daily and was modeled as a time-dependent variable. Results: Among 135,445 qualifying patients with a total of 243,097 person-years, there were 1020 pneumonia incidences out of 5677 person-years on ICS (crude incidence rate, 0.180 per person-year, and 27,730 pneumonia incidences out of 237,420 person-years not on ICS (crude incidence rate, 0.117 per person-year.

    Pneumonia remains a significant cause of morbidity and mortality in the UK and yet the seriousness of the disease is underestimated. Pneumonia can be life-threatening because the delicate tissues of the alveoli and pulmonary capillaries are susceptible to damage from the inflammatory response. This damage leads to consolidation that prevents the diffusion of oxygen and carbon dioxide, and this in turn can lead to respiratory failure. This article summarises guidance on the diagnosis and management of community-acquired pneumonia, and also includes information on the prevention of pneumonia. This information should be valuable to nurses working in a variety of clinical areas since patients with community-acquired pneumonia are encountered in primary, intermediate, secondary and critical care.

    Full Text Available Abstract Background There was a pandemic influenza around the world in 2009 including South Korea since last pandemic occurred four decades ago. We aimed to evaluate the epidemiological and clinical characteristics of this infection in childhood. Methods We evaluated the epidemiologic characteristics of all the subjects infected with the 2009 H1N1 influenza A virus (2,971 patients, ≤ 15 years of age, and the clinical and laboratory findings of the inpatients (217 patients, 80 had pneumonia between 1 September 2009 and 31 January 2010 in a single hospital throughout the epidemic. Results The age distribution of all the subjects was relatively even. Over 90% of cases occurred during a two-month period. Two hundred and five patients (94.5% received oseltamivir within 48 h of fever onset, and 97% of inpatients defervesced within 48 h of medication. The group with pneumonia included more males than females, and had higher leukocytes counts with lower lymphocyte differentials than the group without pneumonia. The white blood cell count and lymphocyte differential were associated with the severity of pneumonia. Corticosteroid treatment for severe pneumonia patients was highly effective in preventing disease progression. Conclusion Children of all ages affected with even rates of infection, but males were predominant in pneumonia patients. Pneumonia patients showed lymphopenia and its severity was associated with the severity of illness. Our results suggest that the mechanism of lung injury in 2009 H1N1 virus infection may be associated with the host immune response.

    Despite the widespread incidence of childhood sexual abuse, there is insufficient investigation into the childhood sexual history of perpetrators. In addition, there is little published on the specific similarities between childhood and adult sexual histories. The present study investigates the incidence of childhood sexual abuse in a carefully characterized sample of male pedophiles compared with a demographically similar control group. Concordance between and cognitive distortions about characteristics of childhood abuse and pedophilic behavior are also studied. Twenty men with pedophilia, heterosexual type were compared with 24 demographically similar, healthy male control subjects on a questionnaire specifically designed to assess childhood sexual history in pedophiles. Sixty percent of pedophiles compared with 4% of control subjects reported adult sexual advances as a child. Seventy-five percent of pedophiles and 22% of control subjects reported a first sexual encounter before age 14 years. About 60% concordance was found between acts experienced as a child and perpetrated as an adult. Finally, numerous inconsistencies throughout the questionnaire add preliminary support for the role of cognitive distortions with regard to childhood and adult sexual history. The present findings replicate the elevated rate of childhood sexual abuse found among pedophiles and are consistent with the notion of a causative relationship between early childhood abuse and later pedophilic behavior.

    Rates of acute Chlamydia pneumoniae and Mycoplasma pneumoniae infections were determined in 115 adults hospitalized for community-acquired pneumonia (CAP), purulent exacerbations of COPD and acute exacerbations of bronchial asthma, by means of serology and molecular methods. Results were compared with those obtained in a matched control group. Common respiratory pathogens were isolated by cultures in 22.5% and 22.2% of CAP and exacerbated COPD patients, respectively. Cultures from exacerbated asthma patients were always negative. Serological and molecular evidence of current C. pneumoniae infection was obtained in 10.0%, 8.9% and 3.3% of CAP, COPD and asthma cases. The corresponding rates of acute M. pneumoniae infection were 17.5%, 6.7% and 3.3%, respectively. Finally, no difference was found between typical and atypical pathogen rates. These findings highlight the importance of taking into account C. pneumoniae and M. pneumoniae infections in guiding the choice of empirical antibacterial treatment for CAP and purulent exacerbations of COPD.

    Full Text Available Organizing pneumonia is a clinical entity asociated with nonspecific symptoms and radiological findings and abnormalities in pulmonary function tests. It is defined by the characteristic histopathological pattern: filling of alveoli and respiratory bronchioles by plugs of granulation tissue. It can be idiopathic (COP or secondary to other causes (SOP. It is an unusual finding and the clinical and radiographic findings are nonspecific. For specific diagnosis an invasive procedure has to be done, but often empirical treatment is started when there's a clinical suspicion. We describe the clinical characteristics of 13 patients with histological diagnosis of organizing pneumonia. Data was obtained from their medical records. The median age was 76 years and the median time to diagnosis from the onset of symptoms was 31 days. In 10 cases the diagnosis was made by transbronchial biopsy. 8 patients required hospitalization, 4 of them received high doses of steroids and 3 required ventilatory support. One patient died from a cause attributable to this entity and 5 relapsed. Dyspnea, cough and fever were the most frequent symptoms. Most patients had more than one tomographic pattern being the most common ground glass opacities and alveolar consolidation. Nine patients were diagnosed with COP and 4 with SOP. The most frequent underlying cause of SOP was drug toxicity. The clinical characteristics of the reported cases are consistent with previously published series. As an interesting feature, there was a group of patients that needed high doses of steroids and ventilatory support.

    To compare pulmonary high-resolution CT (HRCT) findings in patients with Pseudomonas aeruginosa pneumonia to HRCT findings in patients with Cytomegalovirus (CMV) pneumonia. We studied 124 patients (77 men, 47 women; age range, 20-89 years; mean age, 65.4 years) with P. aeruginosa pneumonia and 44 patients (22 men, 22 women; age range, 36-86 years; mean age, 63.2 years) with CMV pneumonia. CT findings of consolidation (p < 0.005), bronchial wall thickening (p < 0.001), cavity (p < 0.05), and pleural effusion (p < 0.001) were significantly more frequent in patients with P. aeruginosa pneumonia than in those with CMV pneumonia. Centrilobular nodules, a crazy-paving appearance, and nodules were significantly more frequent in patients with CMV pneumonia than in those with P. aeruginosa pneumonia (all p < 0.001). Pulmonary HRCT findings, such as bronchial wall thickening, crazy-paving appearance, and nodules may be useful in distinguishing between P. aeruginosa pneumonia and CMV pneumonia. (orig.)

    Chylothorax is a disease in which chyle leaks and accumulates in the thoracic cavity. Interstitial pneumonia and pneumomediastinum are common thoracic manifestations of dermatomyositis, but chylothorax complicated with dermatomyositis is not reported. We report a case of dermatomyositis with interstitial pneumonia complicated by chylothorax. A 77-year-old woman was diagnosed as dermatomyositis with Gottron's papules, skin ulcers, anti-MDA5 antibody and rapid progressive interstitial pneumonia. Treatment with betamethasone, tacrolimus and intravenous high-dose cyclophosphamide was initiated, and her skin symptoms and interstitial pneumonia improved once. However, right-sided chylothorax began to accumulate and gradually increase, and at the same time, her interstitial pneumonia began to exacerbate, and skin ulcers began to reappear on her fingers and auricles. Although her chylothorax improved by fasting and parenteral nutrition, she died due to further exacerbations of dermatomyositis and interstitial pneumonia in spite of steroid pulse therapy, increase in the betamethasone dosage, additional intravenous high-dose cyclophosphamide and plasma pheresis. An autopsy showed no lesions such as malignant tumors in the thoracic cavity. This is the first report of chylothorax complicated by dermatomyositis with interstitial pneumonia.

  8. Evolving trends in Streptococcus pneumoniae resistance: implications for therapy of community-acquired bacterial pneumonia.

    Jones, Ronald N; Jacobs, Michael R; Sader, Helio S

    2010-09-01

    Pneumonia is a major infectious disease associated with significant morbidity, mortality and utilisation of healthcare resources. Streptococcus pneumoniae is the predominant pathogen in community-acquired pneumonia (CAP), accounting for 20-60% of bacterial cases. Emergence of multidrug-resistant S. pneumoniae has become a significant problem in the management of CAP. Although pneumococcal conjugate vaccine usage in children has led to significant decreases in morbidity and mortality due to S. pneumoniae in all age groups, disease management has been further complicated by the unexpected increase in resistant serotypes, such as 19A, in some regions. Until rapid and accurate diagnostic tests become available, initial treatment of CAP will remain empirical. Thus, selection of appropriate antimicrobial therapy for CAP must be based on prediction of the most likely pathogens and their local antimicrobial susceptibility patterns. This article reviews information on antimicrobial resistance patterns amongst S. pneumoniae and implications for managing CAP.

    Acid-suppressive drugs, including histamine-2 receptor antagonists (H2RAs) and proton pump inhibitors (PPIs), are common medications used for treating upper gastrointestinal tract disorders. However, acid-suppressive drugs have been reported to increase the risk of pneumonia in numerous disease populations. However, the relationship between acid-suppressive drugs and stroke-associated pneumonia (SAP) remains controversial. The purpose of this study was to investigate the association between acid-suppressive drug usage and pneumonia among patients with stroke by using a nationwide data set. A population-based cohort study was conducted using a data set from the Taiwanese National Health Insurance Research Database. Data on patients with new-onset stroke from 2010 to 2011 were collected. Patients with and without acid-suppressive drug usage were followed up to identify the occurrence of any type of pneumonia. We estimated the adjusted hazard ratios (HRs) by using the Cox proportional hazards model. The study cohort comprised 7965 patients with new-onset stroke. The incidence of pneumonia was 6.9% (552/7965) and more than 40% (225/552) of patients developed pneumonia within 3 months after an acute stroke. Acid-suppressive drug usage was an independent risk factor of pneumonia. The adjusted HR for the risk of pneumonia in patients with new-onset stroke using acid-suppressive drugs was 1.44 (95% confidence interval [CI] = 1.18-1.75, P usage increased risk of chronic SAP (adjusted HR = 1.46, 95% CI = 1.04-2.05). Acid-suppressive drug usage was associated with a slightly increased risk of SAP. Physicians should exercise caution when prescribing acid-suppressive drugs to patients with stroke, particularly at the chronic stage.

We simultaneously assessed these risk factors in Quito, Ecuador. Methods In 2005, we studied two socioeconomically similar neighborhoods in Quito: Lucha de los Pobres (LP and Jaime Roldos (JR. LP had relatively high levels of air pollution (annual median PM2.5 = 20.4 μg/m3; NO2 = 29.5 μg/m3 compared to JR (annual median PM2.5 = 15.3 μg/m3; NO2 = 16.6 μg/m3. We enrolled 408 children from LP (more polluted and 413 children from JR (less polluted. All subjects were aged 18-42 months. We obtained medical histories of prior physician visits and hospitalizations during the previous year, anthropometric nutrition data, hemoglobin levels, and hemoglobin oxygen saturation via oximetry. Results In anemic children, higher pollution exposure was significantly associated with pneumonia hospitalization (OR = 6.82, 95%CI = 1.45-32.00; P = 0.015. In non-anemic children, no difference in hospitalizations by pollution exposure status was detected (OR = 1.04, NS. Children exposed to higher levels of air pollution had more pneumonia hospitalizations (OR = 3.68, 1.09-12.44; P = 0.036, total respiratory illness (OR = 2.93, 95% CI 1.92-4.47; P Conclusions Ambient air pollution is associated with rates of hospitalization for pneumonia and with physician's consultations for acute respiratory infections. Anemia may interact with air pollution to increase pneumonia hospitalizations. If confirmed in larger studies, improving nutrition-related anemia, as well as decreasing the levels of air pollution in Quito, may reduce pneumonia incidence.

    2005-01-01

    Drug related incidents are a common form of reported medical errors. This paper reviews the critical incidents related to drug errors reported from the main operating theatre suite in a teaching hospital in a developing country from January 1997 to December 2002. Each report was evaluated individually by two reviewers using a structured process. During this period, 44 874 anaesthetics were administered; 768 critical incidents were reported, 165 (21%) of which were related to drug errors. Underdosage, side-effect/drug reaction and syringe swap were the most common. A total of 76% were classified as preventable; 56% due to human error and 19% due to system error. High risk incidents accounted for 10% of all drug errors and most of these were related to the use of neuromuscular blocking drugs. This analysis has been found useful in addressing some issues about priorities.

    2016-01-01

    Klebsiella pneumoniae is a common cause of hospital-acquired pneumonia. Granzymes (gzms), mainly found in cytotoxic lymphocytes, have been implicated as mediators of infection and inflammation. We here sought to investigate the role of gzmA and gzmB in the host response to K. pneumoniae-induced airway infection and sepsis. For this purpose, pneumonia was induced in wild-type (WT) and gzmA-deficient (gzmA-/-), gzmB-/- and gzmAxB-/- mice by intranasal infection with K. pneumoniae. In WT mice, gzmA and gzmB were mainly expressed by natural killer cells. Pneumonia was associated with reduced intracellular gzmA and increased intracellular gzmB levels. Gzm deficiency had little impact on antibacterial defence: gzmA-/- and gzmAxB-/- mice transiently showed modestly higher bacterial loads in the lungs but not in distant organs. GzmB-/- and, to a larger extent, gzmAxB-/- mice displayed transiently increased lung inflammation, reflected in the semi-quantitative histology scores and levels of pro-inflammatory cytokines and chemokines. Most differences between gzm-deficient and WT mice had disappeared during late-stage pneumonia. Gzm deficiency did not impact on distant organ injury or survival. These results suggest that gzmA and gzmB partly regulate local inflammation during early pneumonia but eventually play an insignificant role during pneumosepsis by the common human pathogen K. pneumoniae.

    The purpose of this paper is to describe an improvement initiative designed to implement nurse sensitive interventions known to reduce patients' risk for ventilator associated pneumonia (VAP), in cardiothoracic intensive care patients. This initiative is a part of one Australian critical care unit's efforts to identify and measure compliance with key nursing interventions known to improve cardiac surgical patients' outcomes. The premise behind the initiative is that improved nursing process and surveillance systems allow emerging trends to catalyse action and motivate nurses to reduce patients' risk for infection acquisition. At five and nine months following implementation of the initiative a>70% compliance rate in 11 out of the 15 nurse sensitive interventions known to reduce patients' risks for VAP and a drop in VAP incidence from 13.4% to 7.69% from per 1000 ventilator days was accomplished.

  2. Geriatric oral health and pneumonia risk.

    Science.gov (United States)

    Terpenning, Margaret

    2005-06-15

    The oral cavity is a complex microenvironment consisting of multiple bacterial and fungal species, their associated biofilms, and a cytokine milieu influenced by constant inflammatory stimulation. Multiple infectious consequences of poor oral health have been extensively described and primarily affect older adults. Probably the most common sequelae of poor oral health in aged persons is a risk of aspiration pneumonia. The risk of aspiration pneumonia is greatest when periodontal disease, dental caries, and poor oral hygiene are compounded by swallowing disease, feeding problems, and poor functional status. The effectiveness of oral hygiene interventions for preventing aspiration pneumonia and barriers to oral care of nursing home patients require additional study, but the current state of research in these areas is reviewed in this manuscript. The expense of aspiration pneumonia as a nursing home complication makes dental hygiene a potentially cost-saving intervention.

    Full Text Available In this issue of the Journal, Patrick et al (pages 298-300 report on the results of a pilot study testing the hypothesis that seropositivity to Chlamydia pneumoniae together with a specific bacteriophage protein is associated with first-episode myocardial infarction or unstable angina. The study evolved from an earlier report suggesting that C pneumoniae with phage seropositivity was strongly associated with the presence of abdominal aortic aneurysm. The phage association suggested a potential explanation for some of the variability in previous studies exploring C pneumoniae as a cause for atherosclerosis (ie, only selected strains of C pneumoniae were pathogenic. Patrick et al found no significant association or trend, and the authors concluded that the negative findings in their pilot study did not support further studies to address this potential association.

  4. Nosocomial pneumonia : rationalizing the approach to empirical therapy.

    Andriesse, Gunnar I; Verhoef, Jan

    2006-01-01

    Nosocomial pneumonia or hospital-acquired pneumonia (HAP) causes considerable morbidity and mortality. It is the second most common nosocomial infection and the leading cause of death from hospital-acquired infections. In 1996 the American Thoracic Society (ATS) published guidelines for empirical therapy of HAP. This review focuses on the literature that has appeared since the ATS statement. Early diagnosis of HAP and its etiology is crucial in guiding empirical therapy. Since 1996, it has become clear that differentiating mere colonization from etiologic pathogens infecting the lower respiratory tract is best achieved by employing bronchoalveolar lavage (BAL) or protected specimen brush (PSB) in combination with quantitative culture and detection of intracellular microorganisms. Endotracheal aspirate and non-bronchoscopic BAL/PSB in combination with quantitative culture provide a good alternative in patients suspected of ventilator-associated pneumonia. Since culture results take 2-3 days, initial therapy of HAP is by definition empirical. Epidemiologic studies have identified the most frequently involved pathogens: Enterobacteriaceae, Haemophilus influenzae, Streptococcus pneumoniae and Staphylococcus aureus ('core pathogens'). Empirical therapy covering only the 'core pathogens' will suffice in patients without risk factors for resistant microorganisms. Studies that have appeared since the ATS statement issued in 1996, demonstrate several new risk factors for HAP with multiresistant pathogens. In patients with risk factors, empirical therapy should consist of antibacterials with a broader spectrum. The most important risk factors for resistant microorganisms are late onset of HAP (>/=5 days after admission), recent use of antibacterial therapy, and mechanical ventilation. Multiresistant bacteria of specific interest are methicillin-resistant S. aureus (MRSA), Pseudomonas aeruginosa, Acinetobacter calcoaceticus-baumannii, Stenotrophomonas maltophilia and extended

    Second primary neoplasms (SPNs) are a recognised late effect of treatment for childhood cancer. Thyroid SPNs can develop after exposure to low-dose radiation, due to the radio-sensitivity of the thyroid gland. The British Childhood Cancer Survivor Study (BCCSS) was set up to directly monitor the late effects of treatment, including risk of SPNs, in childhood cancer survivors and includes 17,980 5-year survivors. We carried out a cohort analysis to determine the risk of thyroid SPNs in the BCCSS, and estimated risk using standardised incidence ratios (SIRs), relative risk (RR) using multivariate Poisson regression and cumulative incidence curves. There were 340,202 person years at risk subsequent to a 5-year survival, median follow-up 17.4 years per survivor. We identified 50 thyroid SPNs including 31 (62%) papillary carcinomas, 15 (30%) follicular carcinomas and 4 (8%) other types. 88% of thyroid SPNs developed after exposure to radiotherapy in or around the thyroid gland. SIR overall was 18.0 (95% confidence interval 13.4-23.8). Risk of thyroid cancer was highest after Hodgkin's disease: RR 3.3 (1.1-10.1) and Non Hodgkin's Lymphoma: RR 3.4 (1.1-10.7) relative to leukaemia (RR 1.0) (p Survivors treated with radiotherapy in childhood had a RR of 4.6 (1.4-15.1) relative to survivors not treated with radiotherapy (RR 1.0), p = 0003. In conclusion, the risk of thyroid cancer in childhood cancer survivors is relatively high in this cohort of childhood cancer survivors. These results will be of use in counselling survivors of childhood cancer exposed to radiation in or around the thyroid area.

    Background Mycoplasma pneumoniae (M. pneumoniae) is a frequent cause of respiratory tract infections. However,there is deficient knowledge about the clinical manifestations of M. pneumoniae infection. We described the clinical and laboratory findings of M. pneumoniae pneumonia in hospitalized children who were all diagnosed by a ≥ fourfold increase in antibody titer.Methods M. pneumoniae antibodies were routinely detected in children admitted with acute respiratory infection during a one-year period. The medical history was re-collected from children whose M. pneumoniae antibody titer increased≥fourfold at the bedside by a single person, and their frozen paired serum samples were measured again for the M.pneumoniae antibody titer.Results Of the 635 children whose sera were detected for the M. pneumoniae antibody, paired sera were obtained from 82 and 29.3% (24/82) showed a ≥ fourfold increase in antibody titer. There were 24 cases, nine boys and 15 girls, aged from two to 14 years, whose second serum samples were taken on day 9 at the earliest after symptom onset; the shortest interval was three days. All children presented with a high fever (≥38.5℃) and coughing. Twenty-one had no nasal obstruction or a runny nose, and five had mild headaches which all were associated with the high fever. The disease was comparatively severe if the peak temperature was >39.5℃. All were diagnosed as having pneumonia through chest X-rays. Four had bilateral or multilobar involvement and their peak temperatures were all ≤ 39.5℃. None of the children had difficulty in breathing and all showed no signs of wheezing.Conclusions The second serum sample could be taken on day 9 at the earliest after symptom onset meant that paired sera could be used for the clinical diagnosis of M. pneumoniae pneumonia in children at the acute stage. M. pneumoniae is a lower respiratory tract pathogen. Extrapulmonary complications were rare and minor in our study. High peak temperature (

    Full Text Available Despite the importance of paediatric pneumonia as a cause of short and long-term morbidity and mortality worldwide, a reliable gold standard for its diagnosis remains elusive. The utility of clinical, microbiological and radiological diagnostic approaches varies widely within and between populations and is heavily dependent on the expertise and resources available in various settings. Here we review the role of radiology in the diagnosis of paediatric pneumonia. Chest radiographs (CXRs are the most widely employed test, however, they are not indicated in ambulatory settings, cannot distinguish between viral and bacterial infections and have a limited role in the ongoing management of disease. A standardised definition of alveolar pneumonia on a CXR exists for epidemiological studies targeting bacterial pneumonias but it should not be extrapolated to clinical settings. Radiography, computed tomography and to a lesser extent ultrasonography and magnetic resonance imaging play an important role in complicated pneumonias but there are limitations that preclude their use as routine diagnostic tools. Large population-based studies are needed in different populations to address many of the knowledge gaps in the radiological diagnosis of pneumonia in children, however, the feasibility of such studies is an important barrier.

    Much effort has been devoted to the metabolic engineering of Klebsiella pneumoniae; however, our knowledge of the actual expression level of promoters used in K. pneumoniae is limited. In this study, the expression levels of three promoters were compared systematically by using the lacZ reporter gene with different carbon sources in K. pneumoniae. The results showed that, although promoters PT5 and Ptac designed for Escherichia coli were functional, PT5 appeared more efficient and the induction/repression ratio of Ptac was decreased extremely in K. pneumoniae. The basal level of Ptac for lacZ expression reached 396.5 U/mg, which was 9.5-fold higher compared with PT5 in LB medium, indicating Ptac can be used as an efficient "constitutive" promoter as well as an efficient induced promoter in K. pneumoniae. In different carbon sources medium, a newly constructed endogenous constitutive Pbud proved to be a stable and weak promoter. On the basis of our data, a set of Pbud and Ptac promoters could meet the broad range (about 1,000 orders of magnitude) of gene expression needed for engineered K. pneumoniae in glycerol-based medium.

  12. Acute and subacute idiopathic interstitial pneumonias.

    Taniguchi, Hiroyuki; Kondoh, Yasuhiro

    2016-07-01

    Idiopathic interstitial pneumonias (IIPs) may have an acute or subacute presentation, or acute exacerbation may occur in a previously subclinical or unrecognized chronic IIP. Acute or subacute IIPs include acute interstitial pneumonia (AIP), cryptogenic organizing pneumonia (COP), nonspecific interstitial pneumonia (NSIP), acute exacerbation of idiopathic pulmonary fibrosis (AE-IPF) and AE-NSIP. Interstitial lung diseases (ILDs) including connective tissue disease (CTD) associated ILD, hypersensitivity pneumonitis, acute eosinophilic pneumonia, drug-induced lung disease and diffuse alveolar haemorrhage need to be differentiated from acute and subacute IIPs. Despite the severe lack of randomized controlled trials for the treatment of acute and subacute IIPs, the mainstream treatment remains corticosteroid therapy. Other potential therapies reported in the literature include corticosteroids and immunosuppression, antibiotics, anticoagulants, neutrophil elastase inhibitor, autoantibody-targeted treatment, antifibrotics and hemoperfusion therapy. With regard to mechanical ventilation, patients in recent studies with acute and subacute IIPs have shown better survival than those in previous studies. Therefore, a careful value-laden decision about the indications for endotracheal intubation should be made for each patient. Noninvasive ventilation may be beneficial to reduce ventilator associated pneumonia.

    Full Text Available Backgound and Objectives: Ventilator-associated pneumonia is a pulmonary infection that occurs 48 to 72 hours after endotracheal intubation and institution of mechanical ventilation, being considered one of the most feared adverse effects of intensive care therapy. Its incidence affects 10-30% of patients as an important cause of morbidity and mortality, of which mortality rate can exceed 25%. Modifiable risk factors are seen as crucial in decision-making for its treatment and prevention. Thus, the modifiable risk factors for pneumonia associated with invasive mechanical ventilation in patients admitted to the intensive care unit were described. Methods: This is a literature review carried out at Lilacs, SciELO, MEDLINE and Bdenf databases, to collect and summarize publications and subsequently, critically evaluate the risk factors for ventilator-associated pneumonia. Results: The inappropriate or indiscriminate use of antibiotics, lack of knowledge about the microbiota of the ICU and non compliance of the team regarding preventive measures predominated. Conclusion: Professionals must be made aware of the identified risk factors in order to carry out direct actions with short-term impact in the prevention and effective control of ventilator-associated pneumonia.

  14. Serologic prevalence of amoeba-associated microorganisms in intensive care unit pneumonia patients.

    Directory of Open Access Journals (Sweden)

    Sabri Bousbia

    Full Text Available BACKGROUND: Patients admitted to intensive care units are frequently exposed to pathogenic microorganisms present in their environment. Exposure to these microbes may lead to the development of hospital-acquired infections that complicate the illness and may be fatal. Amoeba-associated microorganisms (AAMs are frequently isolated from hospital water networks and are reported to be associated to cases of community and hospital-acquired pneumonia. METHODOLOGY/PRINCIPAL FINDINGS: We used a multiplexed immunofluorescence assay to test for the presence of antibodies against AAMs in sera of intensive care unit (ICU pneumonia patients and compared to patients at the admission to the ICU (controls. Our results show that some AAMs may be more frequently detected in patients who had hospital-acquired pneumonia than in controls, whereas other AAMs are ubiquitously detected. However, ICU patients seem to exhibit increasing immune response to AAMs when the ICU stay is prolonged. Moreover, concomitant antibodies responses against seven different microorganisms (5 Rhizobiales, Balneatrix alpica, and Mimivirus were observed in the serum of patients that had a prolonged ICU stay. CONCLUSIONS/SIGNIFICANCE: Our work partially confirms the results of previous studies, which show that ICU patients would be exposed to water amoeba-associated microorganisms, and provides information about the magnitude of AAM infection in ICU patients, especially patients that have a prolonged ICU stay. However, the incidence of this exposure on the development of pneumonia remains to assess.

    Full Text Available Incidences of leukopenia caused by bacteremia have increased significantly and it is associated with prolonged hospital stay and increased cost. Immunoproteomic is a promising method to identify pathogenicity factors of different diseases. In the present study, we used immunoproteomic to analysis the pathogenicity factors in leukopenia caused by Klebsiella Pneumonia bacteremia. Approximately 40 protein spots localized in the 4 to 7 pI range were detected on two-dimensional electrophoresis gels, and 6 differentially expressed protein spots between 10 and 170 kDa were identified. Pathogenicity factors including S-adenosylmethionine synthetase, pyruvate dehydrogenase, glutathione synthetase, UDP-galactose-4-epimerase, acetate kinase A and elongation factor tu (EF-Tu. In validation of the pathogenicity factor, we used western blotting to show that Klebsiella pneumonia had higher (EF-Tu expression when they accompanied by leukopenia rather than leukocytosis. Thus, we report 6 pathogenicity factors of leukopenia caused by Klebsiella pneumonia bacteremia, including 5 housekeeping enzymes and EF-Tu. We suggest EF-Tu could be a potential pathogenicity factor for leukopenia caused by Klebsiella pneumonia.

    Most dental practitioners act as their own radiographer and radiologist, unlike their medical colleagues. Virtually all dental surgeons have a dental X-ray machine for intraoral radiography available to them and 40% of dental practices have equipment for dental panoramic tomography. Because of the low energy of X-ray equipment used in dentistry, radiation incidents tend to be less serious than those associated with other aspects of patient care. Details of 47 known incidents are given. The advent of the 1985 and 1988 Ionising Radiation Regulations has made dental surgeons more aware of the hazards of radiation. These regulations, and general health and safety legislation, have led to a few dental surgeons facing legal action. Because of the publicity associated with these court cases, it is expected that there will be a decrease in radiation incidents arising from the practice of dentistry. (author).

    An epidemiological link was found between contamination of a hospital water-supply by Legionella pneumophila and by Pittsburgh pneumonia agent (PPA) and subsequent cases of nosocomial legionnaires' disease and Pittsburgh pneumonia. The extent of L pneumophila isolation from the water-supply paralleled the occurrence of disease. Whenever L pneumophila was isolated from more than 30% of ten selected water sites, nosocomial legionellosis occurred. The temperature of the hot water tanks was raised to 60-77 degrees C for 72 h, and water outlets were flushed for 30 min with hot water. A decline in numbers of L pneumophila and PPA in the water-supply was followed by a fall in the incidence of legionnaires' disease and Pittsburgh pneumonia. In addition, intermittent raising of the temperature in the hot water system decreased both the number of months in which disease occurred and the proportion of nosocomial pneumonias caused by these organisms.

    The aim of this study was to assess the clinical and pulmonary thin-section CT findings in patients with acute Klebsiella pneumoniae pneumonia. We retrospectively evaluated thin-section CT examinations performed between January 1991 and December 2007 from 962 patients with acute Klebsiella pneumoniae pneumonia. Seven hundred and sixty-four cases with concurrent infectious diseases were excluded. Thus, our study group comprised 198 patients (118 male, 80 female; age range 18-97 years, mean age 61.5). Underlying diseases and clinical findings were assessed. Parenchymal abnormalities were evaluated along with the presence of enlarged lymph nodes and pleural effusion. CT findings in patients with acute Klebsiella pneumoniae pneumonia consisted mainly of ground-glass attenuation (100%), consolidation (91.4%), and intralobular reticular opacity (85.9%), which were found in the periphery (96%) of both sides of the lungs (72.2%) and were often associated with pleural effusion (53%). The underlying conditions in patients with Klebsiella pneumoniae pneumonia were alcoholism or smoking habit. (orig.)

    In the present study, we comparatively assessed the pathophysiological mechanisms developed during lung infection of BALB/C female mice infected by an original wild type Klebsiella pneumoniae subsp. ozaenae strain (CH137) or by a referent subspecies K. pneumoniae. subsp. pneumoniae strain (ATCC10031). The mice infected with 2.10⁶ CFU K. p. subsp. pneumoniae (n = 10) showed transient signs of infection and all of them recovered. All of those infected with 1.10⁶ CFU K. p. subsp. ozaenae (n = 10) developed pneumonia within 24 h and died between 48 and 72 h. Few macrophages, numerous polymorphonuclear cells and lymphocytes were observed in their lungs in opposite to K. p. subsp. pneumoniae. In bronchoalveolar lavage, a significant increase in MIP-2, IL-6, KC and MCP-1 levels was only observed in K. p. subsp. ozaenae infected mice whereas high levels of TNF-α were evidenced with the two subspecies. Our findings indicated a lethal effect of a wild type K. p. subsp. ozaenae strain by acute pneumonia reflecting an insufficient alveolar macrophage response. This model might be of a major interest to comparatively explore the pathogenicity of K. p. subsp ozaenae strains and to further explore the physiopathological mechanisms of gram-negative bacteria induced human pneumonia.

    Ceftobiprole (BAL9141) is an investigational cephalosporin active against methicillin- and vancomycin-resistant staphylococci administered as a water-soluble prodrug, ceftobiprole medocaril (BAL5788). Using an immunocompetent murine pneumonia model of Haemophilus influenzae, Enterobacter cloacae, or extended-spectrum beta-lactamase (ESBL) nonproducing or producing Klebsiella pneumoniae pneumonia, we compared results of treatment with ceftobiprole medocaril (71 mg/kg, sc, qid), ceftriaxone (50 mg/kg, im, bid), or cefepime (50 mg/kg, ip, q.i.d.). Results were expressed as median and 25th to 75th percentile log10 colony forming units per gram of lung tissue. Ceftobiprole, ceftriaxone, and cefepime were each more active than was no treatment and were equally active for treatment of experimental H. influenzae, E. cloacae, or ESBL-nonproducing K. pneumoniae pneumonia. For ESBL-producing K. pneumoniae, no differences were detected between no treatment and treatment with ceftobiprole, ceftriaxone, or cefepime. Ceftobiprole is active against H. influenzae, E. cloacae, and ESBL-nonproducing K. pneumoniae in an immunocompetent experimental murine pneumonia model.

    Streptococcus pneumoniae colonizes the nasopharyngeal mucus in healthy people and causes otitis media, pneumonia, bacteremia, and meningitis. In this study, we analyzed an S. pneumoniae strain that caused 7 repeated pneumonia episodes in an 80-month-old patient with cerebral palsy during a period of 25 months. A total of 10 S. pneumoniae strains were obtained from sputum samples, and serotype 6B was isolated from samples from the first 5 episodes, whereas serotype 6A was isolated from samples from the last 2. Whole-genome sequencing showed clonality of the 10 isolates with 10 single nucleotide polymorphisms (SNPs) in the genomes. Among these SNPs, one single point mutation in the wciP gene was presumed to relate to the serotype switching from 6B to 6A, and the other mutations in parC and gyrA were related to fluoroquinolone resistance. These results suggested that an S. pneumoniae strain, which asymptomatically colonized the patient's nasopharynx or was horizontally transmitted from an asymptomatic carrier, caused the repeated pneumonia events. Phenotypic variations in the capsule type and antimicrobial susceptibility occurred during the carrier state. Hyporesponsiveness to serotypes 6B and 6A of S. pneumoniae was found even after vaccination with the 7-valent pneumococcal conjugate vaccine and the 23-valent pneumococcal polysaccharide vaccine. After an additional vaccination with the 13-valent pneumococcal conjugate vaccine, opsonic activities for both serotypes 6A and 6B significantly increased and are expected to prevent relapse by the same strain.

    There is an increased susceptibility and mortality in the elderly due to pneumonia caused by Streptococcus pneumoniae. We aimed to assess the inflammatory cell composition with respect to age in pneumococcal pneumonia patients. Neutrophilic granulocytes and various lymphocyte and macrophage subpopulations were immunohistochemically quantified on lung tissue specimens of young (n = 5; mean age 8.4 years), middle-aged (n = 8; mean age 55.9 years) and elderly (n = 9; mean age 86.6 years) pneumonia patients with microbiologically proven S. pneumoniae pneumonia. We discovered a higher percentage of neutrophilic granulocytes in elderly as opposed to young patients (95 vs. 75%, p = 0.012). Conversely, young patients versus elderly patients had more alveolar macrophages (CD11c+: 20 vs. 9%, p = 0.029) and M1 macrophages (CD14+: 30 vs. 10%, p = 0.012 and HLA-DR+: 52 vs. 11%, p = 0.019). There was no significant difference concerning M2 macrophages and lymphocytes. Comparison of young patients with middle-aged patients showed similar significant results for alveolar macrophages (p = 0.019) and subsignificant results for M1 macrophages and neutrophilic granulocytes (p pneumonia in situ. Our observations improve the understanding of the innate immune mechanisms of pneumococcal lung infection and point at the potential of therapies for restoring macrophage function and decreasing neutrophilic influx in order to help prevent or cure pneumonia.

    Full Text Available INTRODUCTION: Streptococcus pneumoniae is a worldwide occurring pathogen Nasopharyngeal carriage of Streptococcus pneumoniae precedes pneumonia and other pneumococcal diseases in the community. Little is known about S. pneumoniae carriage in Indonesia, complicating strategies to control pneumococcal diseases. We investigated nasopharyngeal carriage of S. pneumoniae in Semarang, Indonesia. METHODS: A population-based survey was performed in Semarang, Indonesia. Nasopharyngeal swabs and questionnaires were taken from 496 healthy young (6-60 month-old children and 45-70 year-old adults. RESULTS: Forty-three percent of children aged 6-60 months and 11% of adults aged 45-75 years carried S. pneumoniae. Determinants of carriage were being a child (OR 7.7; 95% CI = 4.5-13.0, passive smoking (OR 2.1; 95% CI = 1.3-3.4, and contact with toddler(s at home (OR 3.0; 95% CI = 1.9-4.7. The most frequent serotypes found were 6A/B and 15B/C. The current commercially available vaccines cover <50% serotypes found in children. Twenty-four percent of S. pneumoniae strains were penicillin non-susceptible, and 45% were resistant to cotrimoxazol. CONCLUSIONS: The limited coverage of commercially available vaccines against the serotypes found in this population, and the high proportion of non-susceptibility to penicillin and cotrimoxazol suggest the need for region-specific information and strategies to control S. pneumoniae.

    2013-09-01

    Myelodysplastic syndrome (MDS) comprises of a heterogeneous group of bone marrow disorders resulting from a clonal stem cell defect characterised by cytopenias despite a relatively hypercellular marrow, ineffective hematopoiesis, morphological dysplasia in the marrow elements, no response to hematinics such as iron, B12 or folic acid and risk of progression to leukemia. Myelodysplastic syndrome in childhood is extremely rare and accounts for less than 5% of all hematopoietic neoplasms in children below the age of 14 y. The primary MDS in children, also known as de novo MDS differs from secondary MDS which generally follows congenital or acquired bone marrow (BM) failure syndromes as well as from therapy related MDS, commonly resulting from cytotoxic therapy. MDS associated with Down syndrome which accounts for approximately one-fourth of cases of childhood MDS is now considered a unique biologic entity synonymous with Down syndrome-related myeloid leukemia and is biologically distinct from other cases of childhood MDS. Refractory cytopenia of childhood (RCC) is the commonest type of MDS. Genetic changes predisposing to MDS in childhood remain largely obscure. Monosomy 7 is by-far the commonest cytogenetic abnormality associated with childhood MDS; however most cases of RCC show a normal karyotype. Complex cytogenetic abnormalities and trisomy 8 and trisomy 21 are also occasionally observed. The most effective and curative treatment is Hematopoietic stem cell transplantation and this is particularly effective in children with the monosomy 7 genetic defect as well as those displaying complex karyotype abnormalities provided it is instituted early in the course of the disease.

    We report three cases of drug-induced pneumonia caused by mesalazine. They were all diagnosed as ulcerative colitis and treated with mesalazine orally. Our three cases and literature review revealed that mesalazine-induced pneumonia resemble like eosinophilic pneumonia or organizing pneumonia and that have good prognosis with drug cessation or administration of corticosteroid. The patient of ulcerative colitis is increasing every year and it is anticipated that the patient with mesalazine-induced pneumonia may also increase. In the treatment of ulcerative colitis with mesalazine, we should pay attention with patient's cough or fever for early detection of drug-induced pneumonia.

    In this paper we reported a novel microbial fuel cell (MFC) based on Klebsiella pneumoniae (K. pneumoniae) strain L17 biofilm, which can utilize directly starch and glucose to generate electricity. The electrochemical activity of K. pneumoniae and the performance of the MFC were evaluated by cyclic voltammetry, scanning electron microscope (SEM) and polarization curve measurement. The results indicated that an established K. pneumoniae biofilm cells were responsible for the direct electron transfer from fuels to electrode during electricity production. The SEM observation proved the ability of K. pneumoniae to colonize on the electrode surface. This MFC generated power from the direct electrocatalysis by the K. pneumoniae strain L17 biofilm.

  4. Lightning incidents in Mongolia

    Full Text Available This is one of the first studies that has been conducted in Mongolia on the distribution of lightning incidents. The study covers a 10-year period from 2004 to 2013. The country records a human death rate of 15.4 deaths per 10 million people per year, which is much higher than that of many countries with similar isokeraunic level. The reason may be the low-grown vegetation observed in most rural areas of Mongolia, a surface topography, typical to steppe climate. We suggest modifications to Gomes–Kadir equation for such countries, as it predicts a much lower annual death rate for Mongolia. The lightning incidents spread over the period from May to August with the peak of the number of incidents occurring in July. The worst lightning affected region in the country is the central part. Compared with impacts of other convective disasters such as squalls, thunderstorms and hail, lightning stands as the second highest in the number of incidents, human deaths and animal deaths. Economic losses due to lightning is only about 1% of the total losses due to the four extreme weather phenomena. However, unless precautionary measures are not promoted among the public, this figure of losses may significantly increase with time as the country is undergoing rapid industrialization at present.

  5. Klebsiella pneumoniae Siderophores Induce Inflammation, Bacterial Dissemination, and HIF-1α Stabilization during Pneumonia

    2016-01-01

    ABSTRACT Klebsiella pneumoniae is a Gram-negative pathogen responsible for a wide range of infections, including pneumonia and bacteremia, and is rapidly acquiring antibiotic resistance. K. pneumoniae requires secretion of siderophores, low-molecular-weight, high-affinity iron chelators, for bacterial replication and full virulence. The specific combination of siderophores secreted by K. pneumoniae during infection can impact tissue localization, systemic dissemination, and host survival. However, the effect of these potent iron chelators on the host during infection is unknown. In vitro, siderophores deplete epithelial cell iron, induce cytokine secretion, and activate the master transcription factor hypoxia inducible factor-1α (HIF-1α) protein that controls vascular permeability and inflammatory gene expression. Therefore, we hypothesized that siderophore secretion by K. pneumoniae directly contributes to inflammation and bacterial dissemination during pneumonia. To examine the effects of siderophore secretion independently of bacterial growth, we performed infections with tonB mutants that persist in vivo but are deficient in siderophore import. Using a murine model of pneumonia, we found that siderophore secretion by K. pneumoniae induces the secretion of interleukin-6 (IL-6), CXCL1, and CXCL2, as well as bacterial dissemination to the spleen, compared to siderophore-negative mutants at an equivalent bacterial number. Furthermore, we determined that siderophore-secreting K. pneumoniae stabilized HIF-1α in vivo and that bacterial dissemination to the spleen required alveolar epithelial HIF-1α. Our results indicate that siderophores act directly on the host to induce inflammatory cytokines and bacterial dissemination and that HIF-1α is a susceptibility factor for bacterial invasion during pneumonia.

To examine the effects of siderophore secretion independently of bacterial growth, we performed infections with tonB mutants that persist in vivo but are deficient in siderophore import. Using a murine model of pneumonia, we found that siderophore secretion by K. pneumoniae induces the secretion of interleukin-6 (IL-6, CXCL1, and CXCL2, as well as bacterial dissemination to the spleen, compared to siderophore-negative mutants at an equivalent bacterial number. Furthermore, we determined that siderophore-secreting K. pneumoniae stabilized HIF-1α in vivo and that bacterial dissemination to the spleen required alveolar epithelial HIF-1α. Our results indicate that siderophores act directly on the host to induce inflammatory cytokines and bacterial dissemination and that HIF-1α is a susceptibility factor for bacterial invasion during pneumonia.

    In Thailand, each year approximately 15,000 people die from accidents, a figure exceeded only by cardiovascular diseases. Motor vehicle accidents (MVA) is the principal cause of death and injuries in children of all ages except preschool group. In 1988 there were 554,452 cases of injuries out of which 10,031 died from MVA. In Bangkok alone MVA accounts for an average of 300 childhood and teenage death and 1,900 cases of injuries each year. Falls, burns and poisonings are relatively high in children less than 4 years old while MVA and injuries from sharp and blunt objects of both accidental and non-accidental cases increase with age and become the two leading causes of injury in older children. The sex ratio (F:M) in preschool ages are 1:1.4 and 1:2 in preteen. Poisonings, though less common, are considered to be very important because of their severity. Drugs, hydrocarbon, insecticides, lead and corrosive substances are leading agents. As for injuries caused by animals, 150 cases of rabies were reported each year while around 5,000 cases of snake bites were found in 1987 and 20 per cent of the victims were children. The study from Ramathibodi Hospital revealed that the majority of accidents (65-72%) occur at home and 20 per cent in the street in children younger than 12 years. Peak incidence were found between 5-9 pm. During weekend and holidays the incidence is higher. Ninety-five per cent of the accidents reported were mild cases, 15 per cent moderate, 3 per cent severe and less than 1 per cent caused death.

    Background Pneumonia and urinary tract infections (UTIs) increase morbidity and mortality. There is little epidemiological evidence from large population-based studies on risk factors for these infections and subsequent mortality in total hip arthroplasty (THA) patients. Aim To examine the risk factors of postoperative pneumonia and UTI after THA and their impact on survival. Patients and methods We used the Danish Hip Arthroplasty Register to identify THAs due to osteoarthritis registered from 2000 to 2013. We collected data about comorbidities, mortality and infections in relation to primary hospitalization and potential predictive variables from administrative databases. Regression models were used to estimate associations between potential risk factors and infection, and subsequently, between infection and mortality. Results In total 84,812 THAs were included. The cumulative incidence of pneumonia and UTI within 7 days of the primary procedure were 0.21 (95% confidence interval [CI]: 0.18–0.25) and 0.29 (95% CI: 0.26–0.33), respectively. Patient-related risk factors for infection were being 80 years or older, gender and a comorbidity burden at time of surgery. The hazard ratio (HR) of dying within 90 days of the primary THA was 10.67 (95% CI: 5.79–19.57) compared to patients without pneumonia. For patients with UTIs, the HR was 1.64 (95% CI: 0.41–6.59) compared to those without a UTI. Conclusion Pneumonia was associated with an increased short-term risk of dying, despite adjustment for coexisting comorbidity and other potential confounders. Age, gender and comorbidity were the most important risk factors for pneumonia and UTIs. Individual initiatives to reduce the risk of pneumonia in select patient groups may be essential to the effort to optimize outcomes after a THA. PMID:28176979

However, few studies have been performed to explore the risk factors for pneumonia development in patients with PD.Methods: We conducted a nationwide population-based cohort study of patients with PD to identify the risk factors for these patients developing pneumonia. Participants with newly diagnosed PD between 2000 and 2009 were enrolled from the 2000–2010 National Health Insurance Research Database in Taiwan. We compared patients with PD with an incidence of hospitalization with pneumonia vs those without, and Cox proportional hazard models were used to estimate the risk of pneumonia.Results: Of the 2,001 enrolled patients (mean follow-up duration 5.8 years, range: 2.7–14.7 years, 381 (19.0% had an incidence of hospitalization with pneumonia during the study period. Multivariate Cox proportional hazards analysis identified older age group (≥80 years of age, hazard ratio [HR] =3.15 [95% confidence interval 2.32–4.28], male sex (HR =1.59 [1.29–1.96], certain geographic regions (northern, HR =1.36 [1.04–1.78], southern and eastern, HR =1.40 [1.05–1.88], rural areas (HR =1.34 [1.05–1.72], chronic heart

    The effects of tylosin tartrate and tiamutilin were examined in pneumonias induced experimentally in neonatal piglets with a homogenate of pneumonic pig lung, obtained from pigs with naturally acquired enzootic pneumonia. The homogenate contained mycoplasmas, including Mycoplasma hyopneumoniae (M suipneumoniae) and M hyorhinis, and certain bacteria and viruses. The experimental pneumonias generally resembled mycoplasmal pneumonia histologically but were complicated by aspiration pneumonia in some animals. both tylosin tartrate (50 mg/kg) and tiamutilin (10 mg/kg) administered orally twice daily for 10 days, beginning 14 days after intranasal infection, significantly reduced the incidence and severity of macroscopical pneumonic lung lesions. M hyopneumoniae could be isolated from the lungs of the unmedicated piglets, but not from drug-treated piglets. The numbers of M hyorhinis, Acholeplasma granularum, Haemophilus parasuis, Pasteurella multocida and P haemolytica in the lung tissue of the infected piglets were significantly reduced by drug therapy. The role of bacterial in the experimental infection appeared to be that of secondary invaders.
