    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.

    Pneumonia is an illness, usually caused by infection, in which the lungs become inflamed and congested, reducing oxygen exchange and leading to cough and breathlessness. It affects individuals of all ages but occurs most frequently in children and the elderly. Among children, pneumonia is the most common cause of death worldwide. Historically, in developed countries, deaths from pneumonia have been reduced by improvements in living conditions, air quality, and nutrition. In the developing wor...

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

    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

    WHO recommendations for early antimicrobial treatment of childhood pneumonia have been effective in reducing childhood mortality, but the last major revision was over 10 years ago. The emergence of antimicrobial resistance, new pneumonia pathogens, and new drugs have prompted WHO to assemble an international panel to review the literature on childhood pneumonia and to develop evidence-based recommendations for the empirical treatment of non-severe pneumonia among children managed by first-level health providers. Treatment should target the bacterial causes most likely to lead to severe disease, including Streptoccocus pneumoniae and Haemophilus influenzae. The best first-line agent is amoxicillin, given twice daily for 3-5 days, although co-trimoxazole may be an alternative in some settings. Treatment failure should be defined in a child who develops signs warranting immediate referral or who does not have a decrease in respiratory rate after 48-72 h of therapy. If failure occurs, and no indication for immediate referral exists, possible explanations for failure should be systematically determined, including non-adherence to therapy and alternative diagnoses. If failure of the first-line agent remains a possible explanation, suitable second-line agents include high-dose amoxicillin-clavulanic acid with or without an affordable macrolide for children over 3 years of age.

    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

    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.

    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.

    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.

    Full Text Available Abstract Background M. pneumoniae pneumonia (MP has been reported in 10-40% of community-acquired pneumonia cases. We aimed to evaluate the difference of clinical features in children with MP, according to their age and chest radiographic patterns. Methods The diagnosis of MP was made by examinations at both admission and discharge and by two serologic tests: the indirect microparticle agglutinin assay (≥1:40 and the cold agglutinins titer (≥1:32. A total of 191 children with MP were grouped by age: ≤2 years of age (29 patients, 3-5 years of age (81 patients, and ≥6 years of age (81 patients. They were also grouped by pneumonia pattern: bronchopneumonia group (96 patients and segmental/lobar pneumonia group (95 patients. Results Eighty-six patients (45% were seroconverters, and the others showed increased antibody titers during hospitalization. Among the three age groups, the oldest children showed the longest duration of fever, highest C-reactive protein (CRP values, and the most severe pneumonia pattern. The patients with segmental/lobar pneumonia were older and had longer fever duration and lower white blood cell (WBC and lymphocyte counts, compared with those with bronchopneumonia. The patient group with the most severe pulmonary lesions had the most prolonged fever, highest CRP, highest rate of seroconverters, and lowest lymphocyte counts. Thrombocytosis was observed in 8% of patients at admission, but in 33% of patients at discharge. Conclusions In MP, older children had more prolonged fever and more severe pulmonary lesions. The severity of pulmonary lesions was associated with the absence of diagnostic IgM antibodies at presentation and lymphocyte count. Short-term paired IgM serologic test may be mandatory for early and definitive diagnosis of MP.

    Lise Denoeud

    Full Text Available BACKGROUND: Few European countries conduct reactive surveillance of influenza mortality, whereas most monitor morbidity. METHODOLOGY/PRINCIPAL FINDINGS: We developed a simple model based on Poisson seasonal regression to predict excess cases of pneumonia and influenza mortality during influenza epidemics, based on influenza morbidity data and the dominant types/subtypes of circulating viruses. Epidemics were classified in three levels of mortality burden ("high", "moderate" and "low". The model was fitted on 14 influenza seasons and was validated on six subsequent influenza seasons. Five out of the six seasons in the validation set were correctly classified. The average absolute difference between observed and predicted mortality was 2.8 per 100,000 (18% of the average excess mortality and Spearman's rank correlation coefficient was 0.89 (P = 0.05. CONCLUSIONS/SIGNIFICANCE: The method described here can be used to estimate the influenza mortality burden in countries where specific pneumonia and influenza mortality surveillance data are not available.

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

    Letícia Alves Vervloet

    2007-10-01

    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.

  18. The value of early CT in complicated childhood pneumonia

    International Nuclear Information System (INIS)

    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.)

    Childhood pneumonia is the leading cause of death of children under the age of 5 years globally. Diagnostic information on the presence of infection, severity and aetiology (bacterial versus viral) is crucial for appropriate treatment. However, the derivation of such information requires advanced equipment (such as X-rays) and clinical expertise to correctly assess observational clinical signs (such as chest indrawing); both of these are often unavailable in resource-constrained settings. In this study, these challenges were addressed through the development of a suite of data mining tools, facilitating automated diagnosis through quantifiable features. Findings were validated on a large dataset comprising 780 children diagnosed with pneumonia and 801 age-matched healthy controls. Pneumonia was identified via four quantifiable vital signs (98.2% sensitivity and 97.6% specificity). Moreover, it was shown that severity can be determined through a combination of three vital signs and two lung sounds (72.4% sensitivity and 82.2% specificity); addition of a conventional biomarker (C-reactive protein) further improved severity predictions (89.1% sensitivity and 81.3% specificity). Finally, we demonstrated that aetiology can be determined using three vital signs and a newly proposed biomarker (lipocalin-2) (81.8% sensitivity and 90.6% specificity). These results suggest that a suite of carefully designed machine learning tools can be used to support multi-faceted diagnosis of childhood pneumonia in resource-constrained settings, compensating for the shortage of expensive equipment and highly trained clinicians.

  1. Imaging of cavitary necrosis in complicated childhood pneumonia

    International Nuclear Information System (INIS)

    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.)

    Pneumonia is one of the major causes of death in the world. Age-adjusted mortality from pneumonia in the United Kingdom was three times higher than it was in France in 2004. The purpose of this article is to find the underlying determinants of pneumonia mortality differences between these two countries. The main research question is "what are the determinants of pneumonia mortality in the UK and France?" Reviewing the underlying determinants of health inequalities, we expected that behavioral factors, environmental factors, and the health care system would account for the differences, but they do not actually account for much of the differences in Pneumonia mortality between the UK and France. The main difference is due to data quality problems particularly relating to diagnosis and certification in both countries. PMID:25223162

    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.

    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.

    The study aims were to identify CT features that predict outcome of fibrotic idiopathic interstitial pneumonia (IIP) when information from lung biopsy data is unavailable. HRCTs of 146 consecutive patients presenting with fibrotic IIP were studied. Visual estimates were made of the extent of abnormal lung and proportional contribution of fine and coarse reticulation, microcystic (cysts {<=}4 mm) and macrocystic honeycombing. A score for severity of traction bronchiectasis was also assigned. Using death as our primary outcome measure, variables were analysed using the Cox proportional hazards model. CT features predictive of a worse outcome were coarse reticulation, microcystic and macrocystic honeycombing, as well as overall extent of lung abnormality (p < 0.001). Importantly, increased severity of traction bronchiectasis, corrected for extent of parenchymal abnormality, was predictive of poor prognosis regardless of the background pattern of abnormal lung (HR = 1.04, CI = 1.03-1.06, p < 0.001). On bivariate Cox analysis microcystic honeycombing was a more powerful determinant of a poor prognosis than macrocystic honeycombing. In fibrotic IIPs we have shown that increasingly severe traction bronchiectasis is indicative of higher mortality irrespective of the HRCT pattern and extent of disease. Extent of microcystic honeycombing is a more powerful determinant of outcome than macrocystic honeycombing. (orig.)

    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.

  12. Comparison of radiological findings and microbial aetiology of childhood pneumonia

    International Nuclear Information System (INIS)

    61 children were treated in hospital from 1981 to 1982 because of both radiologically and microbiologically verified viral or bacterial pneumonia. The chest radiographs were interpreted by two radiologists, not familiar with the clinical data, on two occasions three years apart, and only those patients with a definite alveolar or interstitial pneumonia at both evaluations were included in the present analysis. In addition, all patients had viral, mixed viral-bacterial or bacterial infections diagnosed by viral or bacterial antibody or antigen assays. Viral infection alone was seen in 7, mixed viral-bacterial infection in 8 and bacterial infection alone in 12 of the 27 patients with alveolar pneumonia. The respective figures were 13, 13 and 8 for the 34 patients with interstitial pneumonia. C-reactive protein concentration was greater than 40 mg/l in 15 of the patients with alveolar and in 11 of the patients with interstitial pneumonia. Thus 74% of the patients with alveolar and 62% with interstitial pneumonia had bacterial infection, either alone or as a mixed viral-bacterial infection. The results suggest that the presence of an alveolar infiltrate in a chest radiograph is a specific but insensitive indicator of bacterial pneumonia. It is concluded that patients with alveolar pneumonia should be treated with antibiotics. In patients with interstitial pneumonia, however, both viral and bacterial aetiology are possible. In those, the decision concerning antibiotic treatment should be based on clinical and laboratory findings. 21 refs., 4 tabs

    Little is known about cause-specific long-term mortality beyond 30 days in pneumonia. We aimed to compare the mortality of patients with hospitalized pneumonia compared to age- and sex-matched controls beyond 30 days. Participants were drawn from the European Prospective Investigation into Cancer (EPIC)-Norfolk prospective population study. Hospitalized pneumonia cases were identified from record linkage (ICD-10: J12-J18). For this study we excluded people with hospitalized pneumonia who died within 30 days. Each case identified was matched to four controls and followed up until the end June 2012 (total 15 074 person-years, mean 6·1 years, range 0·08-15·2 years). Cox regression models were constructed to examine the all-cause, respiratory and cardiovascular mortality using date of pneumonia onset as baseline with binary pneumonia status as exposure. A total of 2465 men and women (503 cases, 1962 controls) [mean age (s.d.) 64·5 (8·3) years] were included in the study. Between a 30-day to 1-year period, hazard ratios (HRs) of all-cause and cardiovascular mortality were 7·3 [95% confidence interval (CI) 5·4-9·9] and 5·9 (95% CI 3·5-9·7), respectively (with very few respiratory deaths within the same period) in cases compared to controls after adjusting for age, sex, asthma, smoking status, pack years, systolic and diastolic blood pressure, diabetes, physical activity, waist-to-hip ratio, prevalent cardiovascular and respiratory diseases. All outcomes assessed also showed increased risk of death in cases compared to controls after 1 year; respiratory cause of death being the most significant during that period (HR 16·4, 95% CI 8·9-30·1). Hospitalized pneumonia was associated with increased all-cause and specific-cause mortality beyond 30 days.

The chest radiographs were interpreted by two radiologists, not familiar with the clinical data, on two occasions three years apart, and only those patients with a definite alveolar (n = 27) or interstitial (n = 34) pneumonia at both evaluations were included in the present analysis. In addition, all patients had viral (n = 20), mixed viral-bacterial (n = 21) or bacterial (n = 20) infections diagnosed by viral or bacterial antibody or antigen assays. Viral infection alone was seen in 7 (26%), mixed viral-bacterial infection in 8 (30%) and bacterial infection alone in 12 (44%) of the 27 patients with alveolar pneumonia. The respective figures were 13 (38%), 13 (38%) and 8 (24%) for the 34 patients with interstitial pneumonia. C-reactive protein concentration was greater than 40 mg/l (a screening limit for viral and bacterial infections) in 15 (56%) of the patients with alveolar and in 11 (32%) of the patients with interstitial pneumonia. Thus 74% of the patients with alveolar and 62% with interstitial pneumonia had bacterial infection, either alone or as a mixed viral-bacterial infection. Our results suggest that the presence of an alveolar infiltrate in a chest radiograph is a specific but insensitive indicator of bacterial pneumonia.

    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.

    Mycoplasma pneumoniae is primarily a respiratory pathogen but may affect exhibit a diverse range of presentations from asymptomatic infection to life threatening conditions. Myocarditis of varying severity is an unusual complication. We report a 6 year old with mycoplasma myocarditis, a rare age for such a presentation, and who responded well to treatment with no sequelae. Serological testing for Mycoplasma pneumoniae should be part of the routine work-up for myocarditis.

    Full Text Available Abstract Background Each year almost one million newborns die from infections, mostly in low-income countries. Timely case management would save many lives but the relative mortality effect of varying strategies is unknown. We have estimated the effect of providing oral, or injectable antibiotics at home or in first-level facilities, and of in-patient hospital care on neonatal mortality from pneumonia and sepsis for use in the Lives Saved Tool (LiST. Methods We conducted systematic searches of multiple databases to identify relevant studies with mortality data. Standardized abstraction tables were used and study quality assessed by adapted GRADE criteria. Meta-analyses were undertaken where appropriate. For interventions with biological plausibility but low quality evidence, a Delphi process was undertaken to estimate effectiveness. Results Searches of 2876 titles identified 7 studies. Among these, 4 evaluated oral antibiotics for neonatal pneumonia in non-randomised, concurrently controlled designs. Meta-analysis suggested reductions in all-cause neonatal mortality (RR 0.75 95% CI 0.64- 0.89; 4 studies and neonatal pneumonia-specific mortality (RR 0.58 95% CI 0.41- 0.82; 3 studies. Two studies (1 RCT, 1 observational study, evaluated community-based neonatal care packages including injectable antibiotics and reported mortality reductions of 44% (RR= 0.56, 95% CI 0.41-0.77 and 34% (RR =0.66, 95% CI 0.47-0.93, but the interpretation of these results is complicated by co-interventions. A third, clinic-based, study reported a case-fatality ratio of 3.3% among neonates treated with injectable antibiotics as outpatients. No studies were identified evaluating injectable antibiotics alone for neonatal pneumonia. Delphi consensus (median from 20 respondents effects on sepsis-specific mortality were 30% reduction for oral antibiotics, 65% for injectable antibiotics and 75% for injectable antibiotics on pneumonia-specific mortality.

    Full Text Available Pneumonia in childhood is endemic in large parts of the world and in particular, in developing countries, as well as in many indigenous communities within developed nations. Haemophilus influenzae type b and Streptococcus pneumoniae conjugate vaccines are currently available against the leading bacterial causes of pneumonia.  The use of the vaccines in both industrialised and developing countries have shown a dramatic reduction in the burden of pneumonia and invasive disease in children.  However, the greatest threat facing pneumococcal conjugate vaccine effectiveness is serotype replacement.  The current vaccines provide serotype-specific, antibody–mediated protection against only a few of the 90+ capsule serotypes.  Therefore, there has been a focus in recent years to rapidly advance technologies that will result in broader disease coverage and more affordable vaccines that can be used in developing countries.  The next generation of pneumococcal vaccines have advanced to clinical trials.

    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.

    Full Text Available Background/Aims: The prognostic role of serum procalcitonin level in critically ill patients with ventilator-associated pneumonia was unclear. The aim of our study was to investigate the relationship between serum procalcitonin level and mortality risk in critically ill patients with ventilator-associated pneumonia. Methods: Data of critically ill patients with ventilator-associated pneumonia were retrospectively collected. Demographics, comorbidities, and serum procalcitonin level were extracted from electronic medical records. The primary outcome was mortality within two months after diagnosis. Multivariable Cox regression analyses were performed to assess the prognostic role of serum procalcitonin level in those patients. Results: A total of 115 critically ill patients with ventilator-associated pneumonia were enrolled in our study. Serum procalcitonin level was not associated with age, gender, or other comorbidities. Univariate Cox regression model showed that high serum procalcitonin level was associated increased risk of morality within 2 months after diagnosis (OR = 2.32, 95% CI 1.25-4.31, P = 0.008. Multivariable Cox regression model showed that high serum procalcitonin level was independently associated increased risk of morality within 2 months after diagnosis (OR = 2.38, 95% CI 1.26-4.50, P = 0.008. Conclusion: High serum procalcitonin level is an independent prognostic biomarker of mortality risk in critically ill patients with ventilator-associated pneumonia, and it's a promising biomarker of prognosis in critically ill patients.

    Rapid mortality surveillance is critical for state emergency preparedness. To enhance timeliness during the 2009-2010 influenza A H1N1 pandemic, the Ohio Department of Health activated a drop-down menu within Ohio's Electronic Death Registration System for reporting of pneumonia- or influenza-related deaths approximately 5 days postmortem. We used International Classification of Diseases-Tenth Revision (ICD-10) codes, available 2-3 months postmortem as the standard, and assessed their agreement with drop-down-menu codes for pneumonia- or influenza-related deaths. Among 56 660 Ohio deaths during September 2009-March 2010, agreement was 97.9% for pneumonia (κ = 0.85) and 99.9% for influenza (κ = 0.79). Sensitivity was 80.2% for pneumonia and 73.9% for influenza. Drop-down menu coding enhanced timeliness while maintaining high agreement with ICD-10 codes. PMID:25521902

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

  10. Inhaled lactonase reduces Pseudomonas aeruginosa quorum sensing and mortality in rat pneumonia.

    Sami Hraiech

    Full Text Available RATIONALE: The effectiveness of antibiotic molecules in treating Pseudomonas aeruginosa pneumonia is reduced as a result of the dissemination of bacterial resistance. The existence of bacterial communication systems, such as quorum sensing, has provided new opportunities of treatment. Lactonases efficiently quench acyl-homoserine lactone-based bacterial quorum sensing, implicating these enzymes as potential new anti-Pseudomonas drugs that might be evaluated in pneumonia. OBJECTIVES: The aim of the present study was to evaluate the ability of a lactonase called SsoPox-I to reduce the mortality of a rat P. aeruginosa pneumonia. METHODS: To assess SsoPox-I-mediated quorum quenching, we first measured the activity of the virulence gene lasB, the synthesis of pyocianin, the proteolytic activity of a bacterial suspension and the formation of biofilm of a PAO1 strain grown in the presence of lactonase. In an acute lethal model of P. aeruginosa pneumonia in rats, we evaluated the effects of an early or deferred intra-tracheal treatment with SsoPox-I on the mortality, lung bacterial count and lung damage. MEASUREMENTS AND PRIMARY RESULTS: SsoPox-I decreased PAO1 lasB virulence gene activity, pyocianin synthesis, proteolytic activity and biofilm formation. The early use of SsoPox-I reduced the mortality of rats with acute pneumonia from 75% to 20%. Histological lung damage was significantly reduced but the lung bacterial count was not modified by the treatment. A delayed treatment was associated with a non-significant reduction of mortality. CONCLUSION: These results demonstrate the protective effects of lactonase SsoPox-I in P. aeruginosa pneumonia and open the way for a future therapeutic use.

    Events causing stress responses during sensitive periods of rapid neurological development in childhood may be early determinants of all-cause premature mortality. Using a British birth cohort study of individuals born in 1958, the relationship between adverse childhood experiences (ACE) and mortality≤50 year was examined for men (n=7,816) and women (n=7,405) separately. ACE were measured using prospectively collected reports from parents and the school: no adversities (70%); one adversity (22%), two or more adversities (8%). A Cox regression model was carried out controlling for early life variables and for characteristics at 23 years. In men the risk of death was 57% higher among those who had experienced 2+ ACE compared to those with none (HR 1.57, 95% CI 1.13, 2.18, p=0.007). In women, a graded relationship was observed between ACE and mortality, the risk increasing as ACE accumulated. Women with one ACE had a 66% increased risk of death (HR 1.66, 95% CI 1.19, 2.33, p=0.003) and those with ≥2 ACE had an 80% increased risk (HR 1.80, 95% CI 1.10, 2.95, p=0.020) versus those with no ACE. Given the small impact of adult life style factors on the association between ACE and premature mortality, biological embedding during sensitive periods in early development is a plausible explanatory mechanism.

    IMPORTANCE In rural India, as in many developing countries, childhood mortality remains high and the quality of health care available is low. Improving care in such settings, where most health care practitioners do not have formal training, requires an assessment of the practitioners’ knowledge of appropriate care and the actual care delivered (the know-do gap). OBJECTIVE To assess the knowledge of local health care practitioners and the quality of care provided by them for childhood diarrhea and pneumonia in rural Bihar, India. DESIGN, SETTING, AND PARTICIPANTS We conducted an observational, cross-sectional study of the knowledge and practice of 340 health care practitioners concerning the diagnosis and treatment of childhood diarrhea and pneumonia in Bihar, India, from June 29 through September 8, 2012. We used data from vignette interviews and unannounced standardized patients (SPs). MAIN OUTCOMES AND MEASURES For SPs and vignettes, practitioner performance was measured using the numbers of key diagnostic questions asked and examinations conducted. The know-do gap was calculated by comparing fractions of practitioners asking key diagnostic questions on each method. Multivariable regressions examined the relation among diagnostic performance, prescription of potentially harmful treatments, and the practitioners’ characteristics. We also examined correct treatment recommended by practitioners with both methods. RESULTS Practitioners asked a mean of 2.9 diagnostic questions and suggested a mean of 0.3 examinations in the diarrhea vignette; mean numbers were 1.4 and 0.8, respectively, for the pneumonia vignette. Although oral rehydration salts, the correct treatment for diarrhea, are commonly available, only 3.5% of practitioners offered them in the diarrhea vignette. With SPs, no practitioner offered the correct treatment for diarrhea, and 13.0% of practitioners offered the correct treatment for pneumonia. Diarrhea treatment has a large know-do gap

    The ratio of the area under the free (unbound) concentration-time curve to minimum inhibitory concentration (fAUC/MIC) was proposed to be the pharmacokinetic/pharmacodynamic index most strongly linked to the antibacterial effect of colistin against Acinetobacter baumannii. A retrospective study of patients who received colistin to treat pneumonia caused by extensively drug-resistant (XDR) A. baumannii over a 4-year period was performed to assess the impact of the colistin MIC on mortality. A total of 227 patients were included in the analysis. The 7-day and 14-day mortality rates of patients with XDR A. baumannii pneumonia receiving colistin therapy were 15.0% and 23.8%, respectively. In the multivariate analysis, Acute Physiology and Chronic Health Evaluation (APACHE) II score, days from index culture to first dose of colistin, underlying tumour and septic shock at presentation were independent predictors of mortality in patients with XDR A. baumannii pneumonia receiving colistin therapy. In the univariate analysis, the colistin dose based on ideal body weight (IBW) correlated with patient outcome. Therefore, the use of IBW appeared to be more appropriate to calculate the colistin dosage. In addition, these results highlight the clinical significance of colistin MIC in patients with XDR A. baumannii pneumonia receiving colistin therapy. Although MICs were in the 'susceptible' range, patients infected with isolates with high colistin MICs showed a poorer clinical response rate than patients infected with isolates with low colistin MICs. Further clinical studies are needed to evaluate the roles of colistin MIC for predicting mortality in XDR A. baumannii pneumonia with a high colistin MIC. PMID:27423416

    We conducted a cluster randomized trial of the effects of the integrated community case management of childhood illness (iCCM) strategy on careseeking for and coverage of correct treatment of suspected pneumonia, diarrhea, and malaria, and mortality among children aged 2-59 months in 31 districts of the Oromia region of Ethiopia. We conducted baseline and endline coverage and mortality surveys approximately 2 years apart, and assessed program strength after about 1 year of implementation. Results showed strong iCCM implementation, with iCCM-trained workers providing generally good quality of care. However, few sick children were taken to iCCM providers (average 16 per month). Difference in differences analyses revealed that careseeking for childhood illness was low and similar in both study arms at baseline and endline, and increased only marginally in intervention (22.9-25.7%) and comparison (23.3-29.3%) areas over the study period (P = 0.77). Mortality declined at similar rates in both study arms. Ethiopia's iCCM program did not generate levels of demand and utilization sufficient to achieve significant increases in intervention coverage and a resulting acceleration in reductions in child mortality. This evaluation has allowed Ethiopia to strengthen its strategic approaches to increasing population demand and use of iCCM services.

    Full Text Available Abstract Background Limited information is available in Iraq regarding the causes of under-five mortality. The vital registration system is deficient in its coverage, particularly from rural areas where access to health services is limited and most deaths occur at home, i.e. outside the health system, and hence the cause of death goes unreported. Knowledge of patterns and trends in causes of under-five mortality is essential for decision-makers in assessing programmatic needs, prioritizing interventions, and monitoring progress. The aim of this study was to identify causes of under-five children deaths using a simplified verbal autopsy questionnaire. The objective was to define the leading symptoms and cause of death among Iraqi children from all regions of Iraq during 1994–1999. Methods To determine the cause structure of child deaths, a simplified verbal autopsy questionnaire was used in interviews conducted in the Iraqi Child & Maternal Mortality Survey (ICMMS 1999 national sample. All the mothers/caregivers of the deceased children were asked open-ended questions about the symptoms within the two weeks preceding death; they could mention more than one symptom. Results The leading cause of death among under-five children was found to be childhood illnesses in 81.2%, followed by sudden death in 8.9% and accidents in 3.3%. Among under-five children dying of illnesses, cough and difficulty in breathing were the main symptoms preceding death in 34.0%, followed by diarrhea in 24.4%. Among neonates the leading cause was cough/and or difficulty in breathing in 42.3%, followed by sudden death in 11.9%, congenital abnormalities in 10.3% and prematurity in 10.2%. Diarrhea was the leading cause of death among infants in 49.8%, followed by cough and/or difficulty in breathing in 26.6%. Among children 12–59 months diarrhea was the leading cause of death in 43.4%, followed by accidents, injuries, and poisoning in 19.3%, then cough/difficulty in

    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.

    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.

    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.

    Background and objectives Inhaled corticosteroids (ICS) and long-acting inhaled bronchodilators (IBD) are beneficial for the management of COPD. Although ICS has been reported to increase the risk of pneumonia in patients with COPD, it remains controversial whether it influences mortality. Using a Japanese national database, we examined the association between preadmission ICS therapy and in-hospital mortality from pneumonia in patients with COPD. Methods We retrospectively collected data from 1,165 hospitals in Japan on patients with COPD who received outpatient inhalation therapy and were admitted with pneumonia. Patients were categorized into those who received ICS with IBD and those who received IBD alone. We performed multivariate logistic regression analysis to examine the association between outpatient ICS therapy and in-hospital mortality, adjusting for the patients’ backgrounds. Results Of the 7,033 eligible patients, the IBD alone group (n=3,331) was more likely to be older, have lower body mass index, poorer general conditions, and more severe pneumonia than the ICS with IBD group (n=3,702). In-hospital mortality was 13.2% and 8.1% in the IBD alone and the ICS with IBD groups, respectively. After adjustment for patients’ backgrounds, the ICS with IBD group had significantly lower mortality than the IBD alone group (adjusted odds ratio, 0.80; 95% confidence interval, 0.68–0.94). Higher mortality was associated with older age, being male, lower body mass index, poorer general status, and more severe pneumonia. Conclusion Outpatient inhaled ICS and IBD therapy was significantly associated with lower mortality from pneumonia in patients with COPD than treatment with IBD alone.

    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: Childhood mortality in Ghana has generally declined in the last four decades. However, estimates tend to conceal substantial variability among regions and districts. The lack of population-based data in Ghana, as in other less developed countries, has hindered the development of effective programmes targeted specifically at clusters where mortality levels are significantly higher. Objective: This paper seeks to test for the existence of statistically significant clusters of childhood mortality within the Kintampo Health and Demographic Surveillance System (KHDSS between 2005 and 2007. Design: In this study, mortality rates were generated using mortality data extracted from the health and demographic surveillance database of the KHDSS and exported into STATA. The spatial and spatio-temporal scan statistic by Kulldorff was used to identify significant clusters of childhood mortality within the KHDSS. Results: A significant cluster of villages with high under-five mortality in the south-eastern part of the KHDSS in 2006 was identified. This is a remote location where poverty levels are relatively higher, health facilities are more sparse and these are compounded by poor transport services in case of emergencies. Conclusion: This study highlights the potential of the surveillance platform to demonstrate the spatial dimensions of childhood mortality clustering. It is apparent, though, that further studies need to be carried out in order to explore the underlying risk factors for potential mortality clusters that could emerge later.

The purpose of this study was to determine how commensal bacteria alter the host response to sepsis. Conventional and germ-free (GF) C57Bl/6 mice were subjected to Pseudomonas aeruginosa pneumonia. All GF mice died within 2 days, whereas 44% of conventional mice survived for 7 days (P = 0.001). Diluting the dose of bacteria 10-fold in GF mice led to similar survival in GF and conventional mice. When animals with similar mortality were assayed for intestinal integrity, GF mice had lower levels of intestinal epithelial apoptosis but similar levels of proliferation and intestinal permeability. Germ-free mice had significantly lower levels of tumor necrosis factor and interleukin 1β in bronchoalveolar lavage fluid compared with conventional mice without changes in systemic cytokine production. Under conventional conditions, sepsis unmasks lymphocyte control of intestinal epithelial apoptosis, because sepsis induces a greater increase in gut apoptosis in Rag-1 mice than in wild-type mice. However, in a separate set of experiments, gut apoptosis was similar between septic GF Rag-1 mice and septic GF wild-type mice. These data demonstrate that the endogenous bacteria play a protective role in mediating mortality from pneumonia-induced sepsis, potentially mediated through altered intestinal apoptosis and the local proinflammatory response. In addition, sepsis-induced lymphocyte-dependent increases in gut epithelial apoptosis appear to be mediated by the endogenous bacteria. PMID:23042193

    Full Text Available Background: Assessing the progress in achieving the United Nation's Millennium Development Goals in terms of population health requires consistent and reliable information on cause-specific mortality, which is often rare in resource-constrained countries. Health and demographic surveillance systems (HDSS have largely used medical personnel to review and assign likely causes of death based on the information gathered from standardized verbal autopsy (VA forms. However, this approach is expensive and time consuming, and it may lead to biased results based on the knowledge and experience of individual clinicians. We assessed the cause-specific mortality for children under 5 years old (under-5 deaths in Siaya County, obtained from a computer-based probabilistic model (InterVA-4. Design: Successfully completed VA interviews for under-5 deaths conducted between January 2003 and December 2010 in the Kenya Medical Research Institute/US Centers for Disease Control and Prevention HDSS were extracted from the VA database and processed using the InterVA-4 (version 4.02 model for interpretation. Cause-specific mortality fractions were then generated from the causes of death produced by the model. Results: A total of 84.33% (6,621 childhood deaths had completed VA data during the study period. Children aged 1–4 years constituted 48.53% of all cases, and 42.50% were from infants. A single cause of death was assigned to 89.18% (5,940 of cases, 8.35% (556 of cases were assigned two causes, and 2.10% (140 were assigned ‘indeterminate’ as cause of death by the InterVA-4 model. Overall, malaria (28.20% was the leading cause of death, followed by acute respiratory infection including pneumonia (25.10%, in under-5 children over the study period. But in the first 5 years of the study period, acute respiratory infection including pneumonia was the main cause of death, followed by malaria. Similar trends were also reported in infants (29 days–11 months and

    Heptavalent pneumococcal conjugate vaccine (PCV7) was introduced to Japan in 2010. We investigated the impact of PCV7 on childhood community-acquired pneumonia (CAP) and pneumococcal pneumonia (PP). Children aged Japan, who were admitted to hospitals were enrolled to estimate the incidence of CAP based on the mid-year population. PP was determined by the presence of Streptococcus pneumoniae in cultured blood and/or sputum samples of CAP patients. The incidence of CAP and S. pneumoniae isolated from PP patients was compared before (April 2008-March 2009) and after (April 2012-March 2013) the introduction of PCV7 immunization. The annual incidence of CAP was reduced [incidence rate ratio 0·81, 95% confidence interval (CI) 0·73-0·90]. When comparing post-vaccine with pre-vaccine periods, the odds ratio for PP incidence was 0·60 (95% CI 0·39-0·93, P = 0·024). PCV7-covered serotypes markedly decreased (66·6% in pre-vaccine vs. 15·6% in post-vaccine, P culture-confirmed PP of vaccine serotypes was observed at 2 years after PCV7 vaccination. PMID:26122538

    Arsenic in drinking water is an established cause of lung, bladder, and skin cancers in adults and may also cause adult kidney and liver cancers. Some evidence for these effects originated from region II of Chile, which had a period of elevated arsenic levels in drinking water, in particular from 1958 to 1970. This unique exposure scenario provides a rare opportunity to investigate the effects of early-life arsenic exposure on childhood mortality; to our knowledge, this is the first study of childhood cancer mortality and high concentrations of arsenic in drinking water. In this article, we compare cancer mortality rates under the age of 20 in region II during 1950 to 2000 with those of unexposed region V, dividing subjects into those born before, during, or after the peak exposure period. Mortality from the most common childhood cancers, leukemia and brain cancer, was not increased in the exposed population. However, we found that childhood liver cancer mortality occurred at higher rates than expected. For those exposed as young children, liver cancer mortality between ages 0 and 19 was especially high: the relative risk (RR) for males born during this period was 8.9 [95% confidence interval (95% CI), 1.7-45.8; P = 0.009]; for females, the corresponding RR was 14.1 (95% CI, 1.6-126; P = 0.018); and for males and females pooled, the RR was 10.6 (95% CI, 2.9-39.2; P water during early childhood may result in an increase in childhood liver cancer mortality.

    Recurrent pneumonia (RP) within 12 months is one of the AIDS diagnosis criteria. To gain knowledge of RP infection in HIV-infected patients, we studied 145 RP cases detected in a cohort of 2,996 HIV patients in Puerto Rico between Jan. 1992-Dec. 2001. The RP prevalence was 4.8%; 77.2% were males and 62.1% were injecting drug users (IDU). At the time of RP diagnosis, the mean CD4+ T cell count was 93.8 cells/mm3, 59.3% were in antiretroviral treatment, 13% had received the pneumococcal vaccine and 84.8% had another AIDS related condition. Over 37% received two or more antiretroviral medications. The death rate in the first year after the RP diagnosis was 63.4%. A Cox proportional hazard analysis showed that CD4+ T cells vaccination percent at the time of RP diagnosis. Low CD4+ T cells significantly increased the hazard and mortality risk of the cases studied. Antecedents of antiretroviral therapy in these patients ensure a better outcome with lower mortality. Efforts to increase the vaccination rate should reduce the RP incidence in our HIV-infected population.

    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.

    Because the epidemiology of pneumonia is changing, we performed an updated, population-based analysis of hospitalization and case-fatality rates for pneumonia patients in the United States. From 2002 to 2011, hospitalization rates decreased significantly for pneumonia caused by pneumococcus and Haemophilus influenzae but increased significantly for Pseudomonas spp., Staphylococcus aureus, and influenza virus.

    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.

    Full Text Available We carried out a case-control study to investigate risk factors for childhood pneumonia in two groups of 650 children aged under two years in the city of Fortaleza, Ceará, Brazil. The cases were children recruited at the main pediatric hospital with a radiological diagnosis of pneumonia, and controls were children of the same age group recruited from the neighbourhood of the cases. In this paper we focus on variables related to childcare practices. Working mothers, proportion of time the mother had worked since the child was born, and use of day care centers emerged as important risk factors with estimated relative risks of 1.58, 1.76 and 5.22, respectively. Also important were the number of children living in the house and presence of grandparents. However, the presence of siblings under two years and the birth order were not associated with pneumonia. All analysis included adjustment for confounding by income, parents' education, and other risk factors as appropriate. This is the first study from a developing country to identify attendance at day care centers as a risk factor for increased childhood morbidity, in this case pneumonia. This finding is of significant public health importance for countries such as Brazil with growing urban populations and an increasing need by mothers to find work outside the home.

  2. Using data-driven rules to predict mortality in severe community acquired pneumonia.

    Full Text Available Prediction of patient-centered outcomes in hospitals is useful for performance benchmarking, resource allocation, and guidance regarding active treatment and withdrawal of care. Yet, their use by clinicians is limited by the complexity of available tools and amount of data required. We propose to use Disjunctive Normal Forms as a novel approach to predict hospital and 90-day mortality from instance-based patient data, comprising demographic, genetic, and physiologic information in a large cohort of patients admitted with severe community acquired pneumonia. We develop two algorithms to efficiently learn Disjunctive Normal Forms, which yield easy-to-interpret rules that explicitly map data to the outcome of interest. Disjunctive Normal Forms achieve higher prediction performance quality compared to a set of state-of-the-art machine learning models, and unveils insights unavailable with standard methods. Disjunctive Normal Forms constitute an intuitive set of prediction rules that could be easily implemented to predict outcomes and guide criteria-based clinical decision making and clinical trial execution, and thus of greater practical usefulness than currently available prediction tools. The Java implementation of the tool JavaDNF will be publicly available.

    Full Text Available Abstract Background A better understanding of potentially modifiable predictors of in-hospital mortality and re-admission to the hospital following discharge may help to improve management of community-acquired pneumonia in older adults. We aimed to assess the associations of potentially modifiable factors with mortality and re-hospitalization in older adults hospitalized with community-acquired pneumonia. Methods A prospective cohort study was conducted from July 2003 to April 2005 in two Canadian cities. Patients aged 65 years or older hospitalized for community-acquired pneumonia were followed up for up to 30 days from initial hospitalization for mortality and these patients who were discharged alive within 30 days of initial hospitalization were followed up to 90 days of initial hospitalization for re-hospitalization. Separate logistic regression analyses were performed identify the predictors of mortality and re-hospitalization. Results Of 717 enrolled patients hospitalized for community-acquired pneumonia, 49 (6.8% died within 30 days of hospital admission. Among these patients, 526 were discharged alive within 30 days of hospitalization of whom 58 (11.2% were re-hospitalized within 90 days of initial hospitalization.

  9. Childhood cancer mortality in relation to the St Lucie nuclear power station

    International Nuclear Information System (INIS)

    An unusual county-wide excess of childhood cancers of brain and other nervous tissue in the late 1990s in St Lucie County, Florida, prompted the Florida Department of Health to conduct a case-control study within the county assessing residential chemical exposures. No clear associations were found, but claims were then made that the release of radioactive substances such as strontium 90 from the St Lucie nuclear power station, which began operating in 1976, might have played a role. To test the plausibility of this hypothesis, we extended by 17 years a previous study of county mortality conducted by the National Cancer Institute. Rates of total cancer, leukaemia and cancer of brain and other nervous tissue in children and across all ages in St Lucie County were evaluated with respect to the years before and after the nuclear power station began operation and contrasted with rates in two similar counties in Florida (Polk and Volusia). Over the prolonged period 1950-2000, no unusual patterns of childhood cancer mortality were found for St Lucie County as a whole. In particular, no unusual patterns of childhood cancer mortality were seen in relation to the start-up of the St Lucie nuclear power station in 1976. Further, there were no significant differences in mortality between the study and comparison counties for any cancer in the time period after the power station was in operation. Relative rates for all childhood cancers and for childhood leukaemia were higher before the nuclear facility began operating than after, while rates of brain and other nervous tissue cancer were slightly lower in St Lucie County than in the two comparison counties for both time periods. Although definitive conclusions cannot be drawn from descriptive studies, these data provide no support for the hypothesis that the operation of the St Lucie nuclear power station has adversely affected the cancer mortality experience of county residents

    Mortality in the ICU frequently results from the synergistic effect of two temporally-distinct infections. This study examined the pathophysiology of a new model of intraabdominal sepsis followed by methicillin-resistant Staphylococcus aureus (MRSA) pneumonia. Mice underwent cecal ligation and puncture (CLP) or sham laparotomy followed three days later by an intratracheal injection of MRSA or saline. Both CLP/saline and sham/MRSA mice had 100% survival while animals with CLP followed by MRSA pneumonia had 67% seven-day survival. Animals subjected to CLP/MRSA had increased bronchoalveolar lavage (BAL) concentrations of MRSA compared to sham/MRSA animals. Animals subjected to sham/MRSA pneumonia had increased BAL levels of IL-6, TNF-α, and G-CSF compared to those given intratracheal saline while CLP/MRSA mice had a blunted local inflammatory response with markedly decreased cytokine levels. Similarly, animals subjected to CLP/saline had increased peritoneal lavage levels of IL-6 and IL-1β compared to those subjected to sham laparotomy while this response was blunted in CLP/MRSA mice. Systemic cytokines were upregulated in both CLP/saline and sham/MRSA mice, and this was blunted by the combination of CLP/MRSA. In contrast, no synergistic effect on pneumonia severity, white blood cell count or lymphocyte apoptosis was identified in CLP/MRSA mice compared to animals with either insult in isolation. These results indicate that a clinically relevant model of CLP followed by MRSA pneumonia causes higher mortality than could have been predicted from studying either infection in isolation, and this was associated with a blunted local (pulmonary and peritoneal) and systemic inflammatory response and decreased ability to clear infection.

The major causes of death were cardiovascular and respiratory. The relative risk of all-cause mortality increased with 21% for every 10 beats/minute increase in heart rate (adjusted HR: 1.21 [1.07-1.36], p = 0.002. The incidence of major non-fatal pulmonary events was 145/1000 py (120-168. The risk of a non-fatal pulmonary complication increased non-significantly with 7% for every 10 beats/minute increase in resting heart rate (adjusted HR: 1.07 [0.96-1.18], p = 0.208. CONCLUSIONS: Increased resting heart rate is a strong and independent risk factor for all-cause mortality in elderly patients with COPD. An increased resting heart rate did not result in an increased risk of exacerbations or pneumonia. This may indicate that the increased mortality risk of COPD is related to non-pulmonary causes. Future randomized controlled trials are needed to investigate whether heart-rate lowering agents are worthwhile for COPD patients.

    Full Text Available OBJECTIVE: To evaluate the association between proximity to a health center and early childhood mortality in Madagascar, and to assess the influence of household wealth, maternal educational attainment, and maternal health on the effects of distance. METHODS: From birth records of subjects in the Demographic and Health Survey, we identified 12565 singleton births from January 2004 to August 2009. After excluding 220 births that lacked global positioning system information for exposure assessment, odds ratios (ORs and their 95% confidence intervals (CIs for neonatal mortality and infant mortality were estimated using multilevel logistic regression models, with 12345 subjects (level 1, nested within 584 village locations (level 2, and in turn nested within 22 regions (level 3. We additionally stratified the subjects by the birth order. We estimated predicted probabilities of each outcome by a three-level model including cross-level interactions between proximity to a health center and household wealth, maternal educational attainment, and maternal anemia. RESULTS: Compared with those who lived >1.5-3.0 km from a health center, the risks for neonatal mortality and infant mortality tended to increase among those who lived further than 5.0 km from a health center; the adjusted ORs for neonatal mortality and infant mortality for those who lived >5.0-10.0 km away from a health center were 1.36 (95% CI: 0.92-2.01 and 1.42 (95% CI: 1.06-1.90, respectively. The positive associations were more pronounced among the second or later child. The distance effects were not modified by household wealth status, maternal educational attainment, or maternal health status. CONCLUSIONS: Our study suggests that distance from a health center is a risk factor for early childhood mortality (primarily, infant mortality in Madagascar by using a large-scale nationally representative dataset. The accessibility to health care in remote areas would be a key factor to achieve

    A matched-propensity analysis of national data from the British Thoracic Society community-acquired pneumonia audit was conducted (n=13 725). Overall, time to first antibiotic (TFA) was ≤4 h in 63%. Adjusted 30-day inpatient (IP) mortality was lower for adults with TFA ≤4 h compared with TFA >4 h (adjusted OR 0.84, 95% CI 0.74 to 0.94; p=0.003). Increasing TFA was associated with greater OR of 30-day IP mortality (p value for trend=0.001), but no TFA threshold was evident. Although we found an association between TFA and mortality, we cannot say whether this is causal or whether TFA might just be a quality measure for overall or other processes of care. PMID:26559161

    Objective To examine whether diabetes mellitus increases the risk of pneumonia mortality among seniors in the U.S. general popula-tion. Methods&Results The NHANES III follow-up study data were used. After excluding individuals from other minorities, being hos-pitalized with pneumonia in the previous year at baseline, or death of pneumonia during the first year of follow-up, a total of 3,707 subjects aged 65 years or older (1,794 men and 1,913 women) who had no missing information on variables for the analysis were included. Approxi-mately 16% of seniors at baseline were diabetics, which was defined as either having been diagnosed by a physician, currently taking pills/insulin lowering blood glucose, or HbA1c higher than 6.4%. During an average 11 years of follow-up, a total of 98 deaths due to pneu-monia were recorded (ICD-10:J12-J18). Cox-regression models were used to estimate the risk association between pneumonia mortality and diabetes mellitus. After adjustment for the covariates at baseline, the hazard ratios of pneumonia death were 1.30 (95%CI:0.64-2.70) for pre-diabetics and 2.28 (95%CI:1.18-4.39) for diabetics, respectively. Among those covariates, only age (HR (95%CI);1.16 (1.13-1.20)), gender as female (0.35 (0.22-0.61)) and physical fitness measured as having no problem walking 1+mile during the previous month (0.38 (0.20-0.67)) reached statistical significance. Conclusions The results suggest that diabetes mellitus is a strong risk predictor of pneumonia mortality and the evaluation of physical fitness may also be useful in the risk prediction of pneumonia mortality for seniors.

  1. Mortality after parental death in childhood: a nationwide cohort study from three Nordic countries.

    Full Text Available BACKGROUND: Bereavement by spousal death and child death in adulthood has been shown to lead to an increased risk of mortality. Maternal death in infancy or parental death in early childhood may have an impact on mortality but evidence has been limited to short-term or selected causes of death. Little is known about long-term or cause-specific mortality after parental death in childhood. METHODS AND FINDINGS: This cohort study included all persons born in Denmark from 1968 to 2008 (n = 2,789,807 and in Sweden from 1973 to 2006 (n = 3,380,301, and a random sample of 89.3% of all born in Finland from 1987 to 2007 (n = 1,131,905. A total of 189,094 persons were included in the exposed cohort when they lost a parent before 18 years old. Log-linear Poisson regression was used to estimate mortality rate ratio (MRR. Parental death was associated with a 50% increased all-cause mortality (MRR = 1.50, 95% CI 1.43-1.58. The risks were increased for most specific cause groups and the highest MRRs were observed when the cause of child death and the cause of parental death were in the same category. Parental unnatural death was associated with a higher mortality risk (MRR = 1.84, 95% CI 1.71-2.00 than parental natural death (MRR = 1.33, 95% CI 1.24-1.41. The magnitude of the associations varied according to type of death and age at bereavement over different follow-up periods. The main limitation of the study is the lack of data on post-bereavement information on the quality of the parent-child relationship, lifestyles, and common physical environment. CONCLUSIONS: Parental death in childhood or adolescence is associated with increased all-cause mortality into early adulthood. Since an increased mortality reflects both genetic susceptibility and long-term impacts of parental death on health and social well-being, our findings have implications in clinical responses and public health strategies.

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

    Directory of Open Access Journals (Sweden)

    Peter Byass

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

    Full Text Available An association between pneumococcal serotypes and mortality has been suggested. We aimed to investigate this among individuals aged ≥15 years with invasive pneumococcal disease (IPD in South Africa.IPD cases were identified through national laboratory-based surveillance at 25 sites, pre-pneumococcal conjugate vaccine (PCV introduction, from 2003-2008. We assessed the association between the 20 commonest serotypes and in-hospital mortality using logistic regression with serotype 4 (the third commonest serotype with intermediate case-fatality ratio (CFR as referent.Among 3953 IPD cases, CFR was 55% (641/1166 for meningitis and 23% (576/2484 for bacteremia (p<0.001. Serotype 19F had the highest CFR (48%, 100/207, followed by serotype 23F (39%, 99/252 and serotype 1 (38%, 246/651. On multivariable analysis, factors independently associated with mortality included serotype 1 (OR 1.9, 95%CI 1.1-3.5 and 19F (OR 2.9, 95%CI 1.4-6.1 vs. serotype 4; increasing age (25-44 years, OR 1.8, 95%CI 1.0-3.0; 45-64 years, OR 3.6, 95%CI 2.0-6.4; ≥65 years, OR 5.2, 95%CI 1.9-14.1; vs. 15-24 years; meningitis (OR 4.1, 95%CI 3.0-5.6 vs. bacteremic pneumonia; and HIV infection (OR1.7, 95%CI 1.0-2.8. On stratified multivariate analysis, serotype 19F was associated with increased mortality amongst bacteremic pneumococcal pneumonia cases, while no serotype was associated with increased mortality in meningitis cases.Mortality was increased in HIV-infected individuals, which may be reduced by increased antiretroviral therapy availability. Serotypes associated with increased mortality are included in the 10-and-13-valent PCV and may become less common in adults due to indirect effects following routine infant immunization.

    Background The ten-valent pneumococcal conjugate vaccine (PCV10) was introduced into the Chilean National Immunization Program (NIP) in January 2011 with a 3+1 schedule (2, 4, 6 and 12 months) without catch-up vaccination. We evaluated the effectiveness of PCV10 on pneumonia morbidity and mortality among infants during the first two years after vaccine introduction. Methods This is a population-based nested case-control study using four merged nationwide case-based electronic health data registries: live birth, vaccination, hospitalization and mortality. Children born in 2010 and 2011 were followed from two moths of age for a period of two years. Using four different case definitions of pneumonia hospitalization and/or mortality (all-cause and pneumonia related deaths), all cases and four randomly selected matched controls per case were selected. Controls were matched to cases on analysis time. Vaccination status was then assessed. Vaccine effectiveness (VE) was estimated using conditional logistic regression. Results There were a total of 497,996 children in the 2010 and 2011 Chilean live-birth cohorts. PCV10 VE was 11.2% (95%CI 8.5–13.6) when all pneumonia hospitalizations and deaths were used to define cases. VE increased to 20.7 (95%CI 17.3–23.8) when ICD10 codes used to denote viral pneumonia were excluded from the case definition. VE estimates on pneumonia deaths and all-cause deaths were 71.5 (95%CI 9.0–91.8) and 34.8 (95% CI 23.7–44.4), respectively. Conclusion PCV10 vaccination substantially reduced the number of hospitalizations due to pneumonia and deaths due to pneumonia and to all-causes over this study period. Our findings also reinforce the importance of having quality health information systems for measuring VE. PMID:27058873

    The present study was aimed at assessing differences between the Nordic countries, if any, in late mortality among five-year survivors of childhood cancer. All cases diagnosed before the age of 20 years, between 1960 and 1989, were collected from all Nordic cancer registries. In total, 13,689 patients were identified as five-year survivors and during the extended follow-up 12.3% of them died. Mortality was analysed by decade of diagnosis, for all sites, and for leukaemia, Hodgkin's lymphoma, and central nervous system tumours separately. Analyses were done within a Cox proportional hazards regression framework with adjustments made for gender and age at diagnosis. Hazard ratios were calculated in relation to a weighted Nordic mean based on the proportion of five-year survivors in each country. Overall late mortality was significantly higher in Denmark and Finland than in Norway and Sweden. This could not be explained by inverse differences in five-year survival. The differences diminished over time and had disappeared in the last period. The pattern was similar for both genders. The disappearance of the differences was most probably the effect of a closer collaboration between Nordic paediatric oncologists with development and implementation of common protocols for treatment of childhood cancers in all countries.

  10. Spatial analysis of the relationship between early childhood mortality and malaria endemicity in Malawi

    2007-11-01

    Full Text Available Spatial differences in mortality have been reported in Africa amongst children under-five years of age. Risk factors contributing to this geographical variation include bio-demographic and socio-economic factors, the prevalence of infectious diseases and the variability in the quality of child health care. This paper is concerned with investigating the link between early childhood mortality and malaria risk. We used data from the Mapping Malaria Risk in Africa (MARA and Demographic and Health Survey (DHS databases to explore this relationship. The DHS survey included questions on bio-demographic and socio-economic status, complete birth histories and survival time of each child within the five years preceding the survey. Survival times were computed in months until death or until the survey was done. The malaria risk was based on prevalence data estimated at the precise DHS sampling location. A spatial Cox regression model was applied to analyze child survival, assessing the influence of both individual-specific factors, malaria endemicity and group-specific environmental factors, approximated by geographical location. Geographical location was considered at subdistrict level. Our analysis shows that although malaria endemicity is not associated with the risk of infant mortality, it is an important risk factor for child mortality. The results confirm the effects of bio-demographic and socio-economic variables (maternal education, maternal age, birth order and place of residence on infant and child mortality. The subdistrict-specific variation of infant and child mortality shows a rural-urban distinction with a relatively lower risk of mortality in main urban areas.

    Full Text Available Despite many reports documenting its epidemicity, little is known on the interaction of Acinetobacter baumannii with its host. To deepen our insight into this relationship, we studied persistence of and host response to different A. baumannii strains including representatives of the European (EU clones I-III in a mouse pneumonia model. Neutropenic mice were inoculated intratracheally with five A. baumannii strains and an A. junii strain and at several days morbidity, mortality, bacterial counts, airway inflammation, and chemo- and cytokine production in lungs and blood were determined. A. baumannii RUH875 and RUH134 (EU clone I and II, respectively and sporadic strain LUH8326 resulted in high morbidity/mortality, whereas A. baumannii LUH5875 (EU clone III, which is less widespread than clone I and II caused less symptoms. A. baumannii type strain RUH3023(T and A. junii LUH5851 did not cause disease. All strains, except A. baumannii RUH3023(T and A. junii LUH5851, survived and multiplied in the lungs for several days. Morbidity and mortality were associated with the severity of lung pathology and a specific immune response characterized by low levels of anti-inflammatory (IL-10 and specific pro-inflammatory (IL-12p40 and IL-23 cytokines at the first day of infection. Altogether, a striking difference in behaviour among the A. baumannii strains was observed with the clone I and II strains being most virulent, whereas the A. baumannii type strain, which is frequently used in virulence studies appeared harmless.

    An unusual mortality event (UME) involving primarily common bottlenose dolphins Tursiops truncatus of all size classes stranding along coastal Louisiana, Mississippi, and Alabama, USA, started in early 2010 and continued into 2014. During this northern Gulf of Mexico UME, a distinct cluster of perinatal dolphins (total body length pneumonia not associated with lungworm infection (65 vs. 19%, p = 0.0001). The percentage of perinates with Brucella sp. infections identified via lung PCR was higher among UME perinates stranding in Mississippi and Alabama compared to reference perinates (61 vs. 24%, p = 0.01), and multiple different Brucella omp genetic sequences were identified in UME perinates. These results support that from 2011 to 2013, during the northern Gulf of Mexico UME, bottlenose dolphins were particularly susceptible to late-term pregnancy failures and development of in utero infections including brucellosis.

    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

    Guoping Hu

    Full Text Available To determine whether the pneumonia severity index (PSI can predict in-hospital mortality for AECOPD patients and compare its usefulness with the CURB65 and BAP65 indexes to predict mortality.Demographics, clinical signs and symptoms, comorbidities, and laboratory and radiographic findings of hospitalized AECOPD patients were obtained. Univariate and multiple logistic regression analyses were used to identify the risk factors for in-hospital mortality. The PSI, CURB65 and BAP65 scores were calculated. Receiver operating characteristic (ROC curve analysis was used to identify the PSI, CURB65 and BAP65 scores that could discriminate between non-survivors and survivors. To control for the confounding factor of invasive mechanical ventilation (IMV regarding the mortality of AECOPD, subgroup analysis was performed when excluded patients who had met the criteria of IMV but who had not received the cure of IMV according to their wishes.During the in-hospital period, 73 patients died and 679 patients recovered. Age, PaO2<60 mmHg, pH < 7.35, PaCO2≥50 mmHg, nursing home residency, congestive heart failure, liver disease, sodium<130 mmol/L, lower FEV1% and altered mental status were risk factors for in-hospital mortality. The areas under the ROC curves (AUCs of the PSI for death were 0.847 (95% CI: 0.799-0.895. The cut-off value was 116.5 with a sensitivity of 82.2% and a specificity of 77.6%. However, the AUCs of the CURB65 and BAP65 for death were only 0.744 (95% CI: 0.680-0.809 and 0.665 (95% CI: 0.594-0.736, respectively. Subgroup analysis also showed that the PSI score could predict the mortality of AECOPD patients with an AUC = 0.857 (95% CI: 0.802-0.913, with exclusion of the patients who met the criteria of IMV but who did not receive the cure of IMV.The PSI score may be used to predict in-hospital mortality for hospitalized AECOPD patients, with a prognostic capacity superior to CURB65 and BAP65.

    Carbapenemase-producing Klebsiella pneumoniae strains (CP-Kps) are currently among the most important nosocomial pathogens. An observational study was conducted during 2009 to 2010 in two hospitals located in a high-prevalence area (Athens, Greece). The aims were (i) to evaluate the clinical outcome of patients with CP-Kp bloodstream infections (BSIs), (ii) to identify predictors of mortality, and (iii) to evaluate the various antibiotic schemes employed. A total of 205 patients with CP-Kp BSIs were identified: 163 (79.5%) were infected with KPC or KPC and VIM, and 42 were infected with VIM producers. For definitive treatment, 103 patients received combination therapy (two or more active drugs), 72 received monotherapy (one active drug), and 12 received therapy with no active drug. The remaining 18 patients died within 48 h after the onset of bacteremia. The all-cause 28-day mortality was 40%. A significantly higher mortality rate was observed in patients treated with monotherapy than in those treated with combination therapy (44.4% versus 27.2%; P=0.018). The lowest mortality rate (19.3%) was observed in patients treated with carbapenem-containing combinations. In the Cox proportion hazards model, ultimately fatal disease (hazards ratio [HR], 3.25; 95% confidence interval [CI], 1.51 to 7.03; P=0.003), the presence of rapidly fatal underlying diseases (HR, 4.20; 95% CI, 2.19 to 8.08; Ptherapy was strongly associated with survival (HR of death for monotherapy versus combination, 2.08; 95% CI, 1.23 to 3.51; P=0.006), mostly due to the effectiveness of the carbapenem-containing regimens.

    Bloodstream infections (BSIs) caused by Klebsiella pneumoniae carbapenemases (KPC)-producing K. pneumoniae (KPC-KP) are associated with high mortality rates. We investigated outcomes, risk factors for mortality and impact of appropriate antimicrobial treatment in patients with BSIs caused by molecularly confirmed KPC-KP. All consecutive patients with KPC-KP BSIs between May 2008 and May 2010 were included in the study and followed-up until their discharge or death. Potential risk factors for infection mortality were examined by a case-control study. Case-patients were those who died from the BSI and control-patients those who survived. Appropriate antimicrobial therapy was defined as treatment with in vitro active antimicrobials for at least 48 h. A total of 53 patients were identified. Overall mortality was 52.8% and infection mortality was 34%. Appropriate antimicrobial therapy was administered to 35 patients; mortality due to infection occurred in 20%. All 20 patients that received combination schemes had favourable infection outcome; in contrast, seven of 15 patients given appropriate monotherapy died (p 0.001). In univariate analysis, risk factors for mortality were age (p catheter-related bacteraemia (p 0.04), prior surgery (p 0.014) and other therapeutic interventions (p 0.015) were significantly associated with survival. Independent predictors of mortality were age, APACHE II score at infection onset and inappropriate antimicrobial treatment. Among them, appropriate treatment is the only modifiable independent predictor of infection outcome.

    Drowning is an important cause of mortality among children in rural Bangladesh. Children aged 1–4 year(s) are at a high risk of death from drowning. Although deaths of children due to drowning in Bangladesh are acknowledged as an important cause of death, little effort has been made to address the issue of preventing deaths from this cause. This study has attempted to describe the problem and suggests possible prevention strategies, which may contribute to reducing childhood mortality from dr...

    Hiroshi Yokomichi

    Full Text Available BACKGROUND: Evidence regarding the mortality rate after administration of the pandemic influenza A (H1N1 2009 vaccine on patients with underlying diseases is currently scarce. We conducted a case-control study in Japan to compare the mortality rates of patients with idiopathic interstitial pneumonia after the vaccines were administered and were not administered. METHODS: Between October 2009 and March 2010, we collected clinical records in Japan and conducted a 1:1 matched case-control study. Patients with idiopathic interstitial pneumonia who died during this period were considered case patients, and those who survived were considered control patients. We determined and compared the proportion of each group that received the pandemic influenza A (H1N1 2009 vaccine and estimated the odds ratio. Finally, we conducted simulations that compensated for the shortcomings of the study associated with adjusted severity of idiopathic interstitial pneumonia. RESULTS: The case and control groups each comprised of 75 patients with idiopathic interstitial pneumonia. The proportion of patients who received the pandemic influenza A (H1N1 2009 vaccine was 30.7% and 38.7% for the case and control groups, respectively. During that winter, the crude conditional odds ratio of mortality was 0.63 (95% confidence interval, 0.25-1.47 and the adjusted conditional odds ratio was 1.18 (95% confidence interval, 0.33-4.49; neither was significant. The simulation study showed more accurate conditional odds ratios of 0.63-0.71. CONCLUSIONS: In our study, we detected no evidence that the influenza A (H1N1 2009 vaccine increased the mortality rate of patients with idiopathic interstitial pneumonia. The results, however, are limited by the small sample size and low statistical power. A larger-scale study is required.

    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.

  2. Estimating oxygen needs for childhood pneumonia in developing country health systems: a new model for expecting the unexpected.

    Directory of Open Access Journals (Sweden)

    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

    Survivors of childhood cancer have a higher mortality than the general population. We describe cause-specific long-term mortality in a population-based cohort of childhood cancer survivors. We included all children diagnosed with cancer in Switzerland (1976-2007) at age 0-14 years, who survived ≥5 years after diagnosis and followed survivors until December 31, 2012. We obtained causes of death (COD) from the Swiss mortality statistics and used data from the Swiss general population to calculate age-, calendar year-, and sex-standardized mortality ratios (SMR), and absolute excess risks (AER) for different COD, by Poisson regression. We included 3,965 survivors and 49,704 person years at risk. Of these, 246 (6.2%) died, which was 11 times higher than expected (SMR 11.0). Mortality was particularly high for diseases of the respiratory (SMR 14.8) and circulatory system (SMR 12.7), and for second cancers (SMR 11.6). The pattern of cause-specific mortality differed by primary cancer diagnosis, and changed with time since diagnosis. In the first 10 years after 5-year survival, 78.9% of excess deaths were caused by recurrence of the original cancer (AER 46.1). Twenty-five years after diagnosis, only 36.5% (AER 9.1) were caused by recurrence, 21.3% by second cancers (AER 5.3) and 33.3% by circulatory diseases (AER 8.3). Our study confirms an elevated mortality in survivors of childhood cancer for at least 30 years after diagnosis with an increased proportion of deaths caused by late toxicities of the treatment. The results underline the importance of clinical follow-up continuing years after the end of treatment for childhood cancer. PMID:26950898

  4. Cause-specific childhood mortality in Africa and Asia: evidence from INDEPTH health and demographic surveillance system sites

    2014-10-01

    Full Text Available Background: Childhood mortality, particularly in the first 5 years of life, is a major global concern and the target of Millennium Development Goal 4. Although the majority of childhood deaths occur in Africa and Asia, these are also the regions where such deaths are least likely to be registered. The INDEPTH Network works to alleviate this problem by collating detailed individual data from defined Health and Demographic Surveillance sites. By registering deaths and carrying out verbal autopsies to determine cause of death across many such sites, using standardised methods, the Network seeks to generate population-based mortality statistics that are not otherwise available. Objective: To present a description of cause-specific mortality rates and fractions over the first 15 years of life as documented by INDEPTH Network sites in sub-Saharan Africa and south-east Asia. Design: All childhood deaths at INDEPTH sites are routinely registered and followed up with verbal autopsy (VA interviews. For this study, VA archives were transformed into the WHO 2012 VA standard format and processed using the InterVA-4 model to assign cause of death. Routine surveillance data also provided person-time denominators for mortality rates. Cause-specific mortality rates and cause-specific mortality fractions are presented according to WHO 2012 VA cause groups for neonatal, infant, 1–4 year and 5–14 year age groups. Results: A total of 28,751 childhood deaths were documented during 4,387,824 person-years over 18 sites. Infant mortality ranged from 11 to 78 per 1,000 live births, with under-5 mortality from 15 to 152 per 1,000 live births. Sites in Vietnam and Kenya accounted for the lowest and highest mortality rates reported. Conclusions: Many children continue to die from relatively preventable causes, particularly in areas with high rates of malaria and HIV/AIDS. Neonatal mortality persists at relatively high, and perhaps sometimes under-documented, rates

    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.

    Clinical isolates of Klebsiella pneumoniae are divided into three phylogroups and differ in their virulence factor contents. The aim of this study was to determine an association between phylogroup, virulence factors and mortality following bloodstream infection (BSI) caused by Klebsiella pneumoniae. Isolates from all adult patients with BSI caused by K. pneumoniae admitted to Karolinska University Hospital, Solna between 2007 and 2009 (n = 139) were included in the study. Phylogenetic analysis was performed based on multilocus sequence typing (MLST) data. Testing for mucoid phenotype, multiplex PCR determining serotypes K1, K2, K5, K20, K54 and K57, and testing for virulence factors connected to more severe disease in previous studies, was also performed. Data was retrieved from medical records including age, sex, comorbidity, central and urinary catheters, time to adequate treatment, hospital-acquired infection, and mortality, to identify risk factors. The primary end-point was 30- day mortality. The three K. pneumoniae phylogroups were represented: KpI (n = 96), KpII (corresponding to K. quasipneumoniae, n = 9) and KpIII (corresponding to K. variicola, n = 34). Phylogroups were not significantly different in baseline characteristics. Overall, the 30-day mortality was 24/139 (17.3%). Isolates belonging to KpIII were associated with the highest 30-day mortality (10/34 cases, 29.4%), whereas KpI isolates were associated with mortality in 13/96 cases (13.5%). This difference was significant both in univariate statistical analysis (P = 0.037) and in multivariate analysis adjusting for age and comorbidity (OR 3.03 (95% CI: 1.10-8.36). Only three of the isolates causing mortality within 30 days belonged to any of the virulent serotypes (K54, n = 1), had a mucoid phenotype (n = 1) and/or contained virulence genes (wcaG n = 1 and wcaG/allS n = 1). In conclusion, the results indicate higher mortality among patients infected with

    Severe malarial anemia (SMA) is a leading cause of morbidity and mortality in children residing in regions where Plasmodium falciparum transmission is holoendemic. Although largely unexplored in children with SMA, interleukin-18 (IL-18) is important for regulating innate and acquired immunity in inflammatory and infectious diseases. As such, we selected two functional single-nucleotide polymorphisms (SNPs) in the IL-18 promoter (-137G→C [rs187238] and -607C→A [rs1946518]) whose haplotypes encompass significant genetic variation due to the presence of strong linkage disequilibrium among these variants. The relationship between the genotypes/haplotypes, SMA (hemoglobin [Hb], sickle cell trait, glucose-6-phosphate dehydrogenase (G6PD) deficiency, HIV-1, and bacteremia revealed that carriage of the -607AA genotype was associated with protection against SMA (odds ratio [OR] = 0.440 [95% confidence interval {CI} = 0.21 to 0.90], P = 0.031) in children with acute infection. In contrast, carriers of the -137G/-607C (GC) haplotype had increased susceptibility to SMA (OR = 2.050 [95% CI = 1.04 to 4.05], P = 0.039). Measurement of IL-18 gene expression in peripheral blood leukocytes demonstrated that elevated IL-18 transcripts were associated with reduced hemoglobin concentrations (ρ = -0.293, P = 0.010) and that carriers of the "susceptible" GC haplotype had elevated IL-18 transcripts (P = 0.026). Longitudinal investigation of clinical outcomes over a 3-year follow-up period revealed that carriers of the rare CC haplotype (∼1% frequency) had 5.76 times higher mortality than noncarriers (P = 0.001). Results presented here demonstrate that IL-18 promoter haplotypes that condition elevated IL-18 gene products during acute infection are associated with increased risk of SMA. Furthermore, carriage of the rare CC haplotype significantly increases the risk of childhood mortality. PMID:21969001

Overall mortality was 52.8% and infection mortality was 34%. Appropriate antimicrobial therapy was administered to 35 patients; mortality due to infection occurred in 20%. All 20 patients that received combination schemes had favourable infection outcome; in contrast, seven of 15 patients given appropriate monotherapy died (p 0.001). In univariate analysis, risk factors for mortality were age (p infection onset (p appropriate antimicrobial treatment (p 0.003), combinations of active antimicrobials (p 0.001), catheter-related bacteraemia (p 0.04), prior surgery (p 0.014) and other therapeutic interventions (p 0.015) were significantly associated with survival. Independent predictors of mortality were age, APACHE II score at infection onset and inappropriate antimicrobial treatment. Among them, appropriate treatment is the only modifiable independent predictor of infection outcome. PMID:21595793

This study examined the pathophysiology of a new model of intra-abdominal sepsis followed by methicillin-resistant Staphylococcus aureus (MRSA) pneumonia. Mice underwent cecal ligation and puncture (CLP) or sham laparotomy followed 3 days later by an intratracheal injection of MRSA or saline. Both CLP/saline and sham/MRSA mice had 100% survival, whereas animals with CLP followed by MRSA pneumonia had 67% 7-day survival. Animals subjected to CLP/MRSA had increased bronchoalveolar lavage concentrations of MRSA compared with sham/MRSA animals. Animals subjected to sham/MRSA pneumonia had increased bronchoalveolar lavage levels of interleukin 6 (IL-6), tumor necrosis factor α, and granulocyte colony-stimulating factor compared with those given intratracheal saline, whereas CLP/MRSA mice had a blunted local inflammatory response with markedly decreased cytokine levels. Similarly, animals subjected to CLP/saline had increased peritoneal lavage levels of IL-6 and IL-1β compared with those subjected to sham laparotomy, whereas this response was blunted in CLP/MRSA mice. Systemic cytokines were upregulated in both CLP/saline and sham/MRSA mice, and this was blunted by the combination of CLP/MRSA. In contrast, no synergistic effect on pneumonia severity, white blood cell count, or lymphocyte apoptosis was identified in CLP/MRSA mice compared with animals with either insult in isolation. These results indicate that a clinically relevant model of CLP followed by MRSA pneumonia causes higher mortality than could have been predicted from studying either infection in isolation, and this was associated with a blunted local (pulmonary and peritoneal) and systemic inflammatory response and decreased ability to clear infection.

    Background Appropriate intervention is critical in reducing deaths among under-five, severe acutely malnourished (SAM) children with danger signs of severe pneumonia; however, there is paucity of data on outcome of World Health Organisation (WHO) recommended interventions of SAM children with severe pneumonia. We sought to evaluate outcome of the interventions in such children. Methods We prospectively enrolled SAM children aged 0–59 months, admitted to the Intensive Care Unit (ICU) or Acute Respiratory Infection (ARI) ward of the Dhaka Hospital of the International Centre for Diarrhoeal Disease Research, Bangladesh (icddr,b), between April 2011 and June 2012 with cough or respiratory difficulty and radiological pneumonia. All the enrolled children were treated with ampicillin and gentamicin, and micronutrients as recommended by the WHO. Comparison was made among pneumonic children with (n = 111) and without WHO defined danger signs of severe pneumonia (n = 296). The outcomes of interest were treatment failure (if a child required changing of antibiotics) and deaths during hospitalization. Further comparison was also made among those who developed treatment failure and who did not and among the survivors and deaths. Results SAM children with danger signs of severe pneumonia more often experienced treatment failure (58% vs. 20%; p<0.001) and fatal outcome (21% vs. 4%; p<0.001) compared to those without danger signs. Only 6/111 (5.4%) SAM children with danger signs of severe pneumonia and 12/296 (4.0%) without danger signs had bacterial isolates from blood. In log-linear binomial regression analysis, after adjusting for potential confounders, danger signs of severe pneumonia, dehydration, hypocalcaemia, and bacteraemia were independently associated both with treatment failure and deaths in SAM children presenting with cough or respiratory difficulty and radiological pneumonia (p<0.01). Conclusion and Significance The result suggests that SAM children with cough or

    A prospective observational study of 226 intensive care unit (ICU) patients was conducted during a 25-month period. Rectal samples were taken at day 1, 4, and 7 and, afterwards, once weekly. Klebsiella pneumoniae was identified using standard techniques, whereas the presence of bla(KPC) gene was confirmed by PCR. During ICU stay, 72.6% of the patients were colonized with Klebsiella pneumoniae carbapenemases (KPC)-producing K. pneumoniae (KPC-Kp). Male gender, prior bed occupants, and patients in nearby beds colonized with KPC-Kp, tracheotomy, number of invasive catheters inserted, and number of antibiotics administered were the major risk factors for KPC-Kp colonization. ICU mortality (35.4%) was significantly related to Simplified Acute Physiology II score and respiratory insufficiency upon admission, cortisone administration, aminoglycoside administration, confirmed KPC-Kp infection, and severe sepsis or septic shock. The high prevalence of KPC-Kp enteric carriage in ICU patients and the significant mortality associated with KPC-Kp infection dictate the importance of early identification and isolation of such carriers.

    Full Text Available Under-five mortality in Nigeria has been reported to be on the decline, but the dynamics are yet to receiveadequate attention. Thus the main objective of this study was to assess these factors and quantify their relativecontributions to under-five mortality between 1990 and 2008. The Nigeria Demographic and HealthSurvey data for 1990, 2003 and 2008 were re-analysed to assess the trends in determinants of under-fivemortality.Cox Regression model was applied to determine the relative contributions of each factor to theunder-five mortality risk.The results showed there were improvements in maternal education (8.6%, childhoodvaccination (17.7%, use of oral rehydration therapy (13.9% and medical treatment of childhood illnesses(17.5% over the 19-year period. There were declines in proportions with birth interval less than 24months (3.9%, access to improved sources of drinking water (24.2%, improved toilet facilities (9.0%antenatal care (4.5%, skilled delivery (3.0% while maternal age at childbirth remained unchanged. Thesefactors increased the death hazards by 4.6% between 1990-2003 but decreased them by 12% between2003 and 2008. It was concluded that Nigeria has recorded very minimal improvements in birth spacing andantenatal/delivery care. Poor access to potable drinking water and sewage disposal, and short birth intervals,are among the factors fuelling childhood mortality risks. Further improvements in these environmental andhealth practices as well as other factors are recommended as strategies for promoting child survival inNigeria.

    Full Text Available Background: Major improvements are required in the coverage and quality of essential childhood interventions to achieve Millennium Development Goal Four (MDG 4. Long distance to health facilities is one of the known barriers to access. We investigated the effect of networked and Euclidean distances from home to formal health facilities on childhood mortality in rural Tanzania between 2005 and 2007. Methods: A secondary analysis of data from a cohort of 28,823 children younger than age 5 between 2005 and 2007 from Ifakara Health and Demographic Surveillance System was carried out. Both Euclidean and networked distances from the household to the nearest health facility were calculated using geographical information system methods. Cox proportional hazard regression models were used to investigate the effect of distance from home to the nearest health facility on child mortality. Results: Children who lived in homes with networked distance >5 km experienced approximately 17% increased mortality risk (HR=1.17; 95% CI 1.02–1.38 compared to those who lived <5 km networked distance to the nearest health facility. Death of a mother (HR=5.87; 95% CI 4.11–8.40, death of preceding sibling (HR=1.9; 95% CI 1.37–2.65, and twin birth (HR=2.9; 95% CI 2.27–3.74 were the strongest independent predictors of child mortality. Conclusions: Physical access to health facilities is a determinant of child mortality in rural Tanzania. Innovations to improve access to health facilities coupled with birth spacing and care at birth are needed to reduce child deaths in rural Tanzania.

    Extended-spectrum-β-lactamase (ESBL)-producing pathogens are associated with extensive morbidity and mortality and rising health care costs. Scant data exist on the impact of antimicrobial therapy on clinical outcomes in patients with ESBL bloodstream infections (BSI), and no large studies have examined the impact of cefepime therapy. A retrospective 3-year study was performed at the Detroit Medical Center on adult patients with BSI due to ESBL-producing Klebsiella pneumoniae or Escherichia coli. Data were collected from the medical records of study patients at five hospitals between January 2005 and December 2007. Multivariate analysis was performed using logistic regression. One hundred forty-five patients with BSI due to ESBL-producing pathogens, including K. pneumoniae (83%) and E. coli (16.5%), were studied. The mean age of the patients was 66 years. Fifty-one percent of the patients were female, and 79.3% were African-American. Fifty-three patients (37%) died in the hospital, and 92 survived to discharge. In bivariate analysis, the variables associated with mortality (P catheter. In multivariate analysis, the predictors of in-hospital mortality included stay in the intensive care unit (odds ratio [OR], 2.17; 95% confidence interval [CI], 0.98 to 4.78), presence of a central-line catheter prior to positive culture (OR, 2.33; 95% CI, 0.77 to 7.03), presence of a rapidly fatal condition at the time of admission (OR, 5.13; 95% CI, 2.13 to 12.39), and recent prior hospitalization (OR, 1.92; 95% CI, 0.83 to 4.09). When carbapenems were added as empirical therapy to the predictor model, there was a trend between empirical carbapenem therapy and decreased mortality (OR, 0.61; 95% CI, 0.26 to 1.50). When added to the model, receipt of empirical cefepime alone (n = 43) was associated with increased mortality, although this association did not reach statistical significance (OR, 1.66; 95% CI, 0.71 to 3.87). The median length of hospital stay was shorter for patients

  3. 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.

    Invasive pneumococcal disease (IPD) and pneumonia are the major causes of morbidity and deaths in children in the world. The management of IPD and pneumonia is an important economic burden on healthcare systems and families. The aim of this study was to assess the economic burden of IPD and pneumonia among younger children in Taiwan. We used a cost-illness approach to identify the cost categories for analysis in this study according to various perspectives. We obtained data of admission, outpatient, and emergency department visit data from the National Health Insurance Research (NHIR) database for children US dollars and were estimated by extrapolating 2008 cost data to 2013 price levels. We estimated the number of pneumococcal disease cases that were averted if the PCV-13 vaccine had been available in 2008. The total annual social and hospital costs for IPD were US $4.3 million and US $926,000, respectively. The total annual social and hospital costs for pneumonia were US $150 million and US $17 million, respectively. On average, families spent US $653 or US $218 when their child was diagnosed with IPD or pneumonia, respectively. This cost is approximately 27%-81% of the monthly salary of an unskilled worker. In conclusion, a safe and effective pediatric pneumococcal vaccine is needed to reduce the economic burden caused by pneumococcal infection. PMID:25874476

    Full Text Available Abstract Background The development of evidence-based clinical practice guidelines has gained wide acceptance in high-income countries and reputable international organizations. Whereas this approach may be a desirable standard, challenges remain in low-income settings with limited capacity and resources for evidence synthesis and guideline development. We present our experience using the Grading of Recommendations Assessment, Development and Evaluation (GRADE approach for the recent revision of the Kenyan pediatric clinical guidelines focusing on antibiotic treatment of pneumonia. Methods A team of health professionals, many with minimal prior experience conducting systematic reviews, carried out evidence synthesis for structured clinical questions. Summaries were compiled and distributed to a panel of clinicians, academicians and policy-makers to generate recommendations based on best available research evidence and locally-relevant contextual factors. Results We reviewed six eligible articles on non-severe and 13 on severe/very severe pneumonia. Moderate quality evidence suggesting similar clinical outcomes comparing amoxicillin and cotrimoxazole for non-severe pneumonia received a strong recommendation against adopting amoxicillin. The panel voted strongly against amoxicillin for severe pneumonia over benzyl penicillin despite moderate quality evidence suggesting clinical equivalence between the two and additional factors favoring amoxicillin. Very low quality evidence suggesting ceftriaxone was as effective as the standard benzyl penicillin plus gentamicin for very severe pneumonia received a strong recommendation supporting the standard treatment. Conclusions Although this exercise may have fallen short of the rigorous requirements recommended by the developers of GRADE, it was arguably an improvement on previous attempts at guideline development in low-income countries and offers valuable lessons for future similar exercises where

    Full Text Available Low birthweight (LBW is associated with increased mortality in infancy, but its association with mortality in later childhood and adolescence is less clear. We investigated the association between birthweight and all-cause mortality and identified major causes of mortality for different birthweight groups.We conducted a population study of all live births occurring in England and Wales between 1 January 1993 and 31 December 2011. Following exclusions, the 12,355,251 live births were classified by birthweight: 500-1,499 g (very LBW [VLBW], n = 139,608, 1,500-2,499 g (LBW, n = 759,283, 2,500-3,499 g (n = 6,511,411, and ≥3,500 g (n = 4,944,949. The association of birthweight group with mortality in infancy (<1 y of age and childhood/adolescence (1-18 y of age was quantified, with and without covariates, through hazard ratios using Cox regression. International Classification of Diseases codes identified causes of death. In all, 74,890 (0.61% individuals died between birth and 18 y of age, with 23% of deaths occurring after infancy. Adjusted hazard ratios for infant deaths were 145 (95% CI 141, 149 and 9.8 (95% CI 9.5, 10.1 for the VLBW and LBW groups, respectively, compared to the ≥3,500 g group. The respective hazard ratios for death occurring at age 1-18 y were 6.6 (95% CI 6.1, 7.1 and 2.9 (95% CI 2.8, 3.1. Male gender, the youngest and oldest maternal age bands, multiple births, and deprivation (Index of Multiple Deprivation score also contributed to increased deaths in the VLBW and LBW groups in both age ranges. In infancy, perinatal factors, particularly respiratory issues and infections, explained 84% and 31% of deaths in the VLBW and LBW groups, respectively; congenital malformations explained 36% and 23% in the LBW group and ≥2,500 g groups (2,500-3,499 g and ≥3,500 g groups combined, respectively. Central nervous system conditions explained 20% of deaths in childhood/adolescence in the VLBW group, with deaths from neoplasms and

    2010-09-01

    The aim of our work was to develop a step-wise concept for investigating neurogenic oropharyngeal dysphagia (NOD) that could be used by both trained nursing staff as well as swallowing therapists and physicians to identify patients with NOD at an early stage and so enable an appropriate therapy to be started. To achieve this objective, we assessed uniform terminology and standard operating procedures (SOP) in a new NOD step-wise concept. In-house stroke mortality rates and rates of pneumonia were measured over time (2003-2009) in order to show improvements in quality of care. In addition, outcome measures in a stroke-unit monitoring system were studied after neurorehabilitation (day 90) assessing quality of life (QL) and patient feedback. An investigation that was carried out in the context of internal and external quality assurance stroke projects revealed a significant correlation between the NOD step-wise concept and low rates of pneumonia and in-house mortality. The quality of life measures show a delta value that can contribute to "post-stroke" depression. The NOD step-wise concept (NSC) should, on the one hand, be capable of being routinely used in clinical care and, on the other, being able to fulfil the requirements of being scientifically based for investigating different stages of swallowing disorders. The value of our NSC relates to the effective management of clinical resources and the provision of adequate diagnostic and therapeutic options for different grades of dysphagia. We anticipate that our concept will provide substantial support to physicians, as well as swallowing therapists, in clinical settings and rehabilitation facilities, thereby promoting better guidance and understanding of neurogenic dysphagia as a concept in acute and rehabilitation care, especially stroke-unit settings.

    2012-01-01

    Background: Beginning in 1958, the city of Antofagasta in northern Chile was exposed to high arsenic concentrations (870 µg/L) when it switched water sources. The exposure abruptly stopped in 1970 when an arsenic-removal plant commenced operations. A unique exposure scenario like this—with an abrupt start, clear end, and large population (125,000 in 1970), all with essentially the same exposure—is rare in environmental epidemiology. Evidence of increased mortality from lung cancer, bronchiectasis, myocardial infarction, and kidney cancer has been reported among young adults who were in utero or children during the high-exposure period. Objective: We investigated other causes of mortality in Antofagasta among 30- to 49-year-old adults who were in utero or ≤ 18 years of age during the high-exposure period. Methods: We compared mortality data between Antofagasta and the rest of Chile for people 30–49 years of age during 1989–2000. We estimated expected deaths from mortality rates in all of Chile, excluding Region II where Antofagasta is located, and calculated standardized mortality ratios (SMRs). Results: We found evidence of increased mortality from bladder cancer [SMR = 18.1; 95% confidence interval (CI): 11.3, 27.4], laryngeal cancer (SMR = 8.1; 95% CI: 3.5, 16.0), liver cancer (SMR = 2.5; 95% CI: 1.6, 3.7), and chronic renal disease (SMR = 2.0; 95% CI: 1.5, 2.8). Conclusions: Taking together our findings in the present study and previous evidence of increased mortality from other causes of death, we conclude that arsenic in Antofagasta drinking water has resulted in the greatest increases in mortality in adults < 50 years of age ever associated with early-life environmental exposure.

    2014-12-01

    Full Text Available OBJECTIVE: Leukemias comprise the most common group of cancers in children and adolescents. Studies conducted in other countries and Brazil have observed a decrease in their mortality.This study aimed to evaluate the trend of mortality from leukemia in children under 19 years of age in Brazil, from 1980 to 2010. METHODS: This was an ecological study, using retrospective time series data from the Mortality Information System, from 1980 to 2010. Calculations of mortality rates were performed, including gross, gender-specific, and age-based. For trend analysis, linear and semi-log regression models were used. The significance level was 5%. RESULTS: Mortality rates for lymphoid and myeloid leukemias presented a growth trend, with the exception of lymphoid leukemia among children under 4 years of age (percentage decrease: 1.21% annually, while in the sub-group "Other types of leukemia", a downward trend was observed. Overall, mortality from leukemia tended to increase for boys and girls, especially in the age groups 10-14 years (annual percentage increase of 1.23% for males and 1.28% for females and 15-19 years (annual percentage increase of 1.40% for males and 1.62% for females. CONCLUSIONS: The results for leukemia generally corroborate the results of other similar studies. A detailed analysis by subgroup of leukemia, age, and gender revealed no trends shown in other studies, thus indicating special requirements for each variable in the analysis.

    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.

    Introduction Measurement of mortality in patients with acute myocardial infarction (AMI), congestive heart failure (CHF) and pneumonia (PN) is a high priority since these are common reasons for hospitalization. However, mortality in patients with inflammatory bowel disease (IBD) that are hospitalized for these common medical conditions is unknown. Methods A retrospective review of the 2005–2011 National Inpatient Sample (NIS), (approximately a 20% sample of discharges from community hospitals) was performed. A dataset for all patients with ICD-9-CM codes for primary diagnosis of acute myocardial infarction, pneumonia or congestive heart failure with a co-diagnosis of IBD, Crohn’s disease (CD) or ulcerative colitis (UC). 1:3 propensity score matching between patients with co-diagnosed disease vs. controls was performed. Continuous variables were compared between IBD and controls. Categorical variables were reported as frequency (percentage) and analyzed by Chi-square tests or Fisher’s exact test for co-diagnosed disease vs. control comparisons. Propensity scores were computed through multivariable logistic regression accounting for demographic and hospital factors. In-hospital mortality between the groups was compared. Results Patients with IBD, CD and UC had improved survival after AMI compared to controls. 94/2280 (4.1%) of patients with IBD and AMI died, compared to 251/5460 (5.5%) of controls, p = 0.01. This represents a 25% improved survival in IBD patients that were hospitalized with AMI. There was a 34% improved survival in patients with CD and AMI. There was a trend toward worsening survival in patients with IBD and CHF. Patients with CD and PN had improved survival compared to controls. 87/3362 (2.59%) patients with CD and PN died, compared to 428/10076 (4.25%) of controls, p < .0001. This represents a 39% improved survival in patients with CD that are hospitalized for PN. Conclusion IBD confers a survival benefit for patients hospitalized with AMI. A

    Objectives To evaluate the effects on non-specific and all cause mortality, in children under 5, of Bacillus Calmette-Guérin (BCG), diphtheria-tetanus-pertussis (DTP), and standard titre measles containing vaccines (MCV); to examine internal validity of the studies; and to examine any modifying effects of sex, age, vaccine sequence, and co-administration of vitamin A. Design Systematic review, including assessment of risk of bias, and meta-analyses of similar studies. Study eligibility criteria Clinical trials, cohort studies, and case-control studies of the effects on mortality of BCG, whole cell DTP, and standard titre MCV in children under 5. Data sources Searches of Medline, Embase, Global Index Medicus, and the WHO International Clinical Trials Registry Platform, supplemented by contact with experts in the field. To avoid overlap in children studied across the included articles, findings from non-overlapping birth cohorts were identified. Results Results from 34 birth cohorts were identified. Most evidence was from observational studies, with some from short term clinical trials. Most studies reported on all cause (rather than non-specific) mortality. Receipt of BCG vaccine was associated with a reduction in all cause mortality: the average relative risks were 0.70 (95% confidence interval 0.49 to 1.01) from five clinical trials and 0.47 (0.32 to 0.69) from nine observational studies at high risk of bias. Receipt of DTP (almost always with oral polio vaccine) was associated with a possible increase in all cause mortality on average (relative risk 1.38, 0.92 to 2.08) from 10 studies at high risk of bias; this effect seemed stronger in girls than in boys. Receipt of standard titre MCV was associated with a reduction in all cause mortality (relative risks 0.74 (0.51 to 1.07) from four clinical trials and 0.51 (0.42 to 0.63) from 18 observational studies at high risk of bias); this effect seemed stronger in girls than in boys.

  3. Why are women so intelligent? The effect of maternal IQ on childhood mortality may be a relevant evolutionary factor.

    Science.gov (United States)

    Charlton, Bruce G

    2010-03-01

    Humans are an unusual species because they exhibit an economic division of labour. Most theories concerning the evolution of specifically human intelligence have focused either on economic problems or sexual selection mechanisms, both of which apply more to men than women. Yet while there is evidence for men having a slightly higher average IQ, the sexual dimorphism of intelligence is not obvious (except at unusually high and low levels). However, a more female-specific selection mechanism concerns the distinctive maternal role in child care during the offspring's early years. It has been reported that increasing maternal intelligence is associated with reducing child mortality. This would lead to a greater level of reproductive success for intelligent women, and since intelligence is substantially heritable, this is a plausible mechanism by which natural selection might tend to increase female intelligence in humans. Any effect of maternal intelligence on improving child survival would likely be amplified by assortative mating for IQ by which people tend to marry others of similar intelligence - combining female maternal and male economic or sexual selection factors. Furthermore, since general intelligence seems to have the functional attribute of general purpose problem-solving and more rapid learning, the advantages of maternal IQ are likely to be greater as the environment for child-rearing is more different from the African hunter-gatherer society and savannah environment in which ancestral humans probably evolved. However, the effect of maternal IQ on child mortality would probably only be of major evolutionary significance in environments where childhood mortality rates were high. The modern situation is that population growth is determined mostly by birth rates; so in modern conditions, maternal intelligence may no longer have a significant effect on reproductive success; the effect of female IQ on reproductive success is often negative. Nonetheless, in the

    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.

    Pneumonia is an acute inflammation of the lower respiratory tract. Lower respiratory tract infection is a major cause of mortality worldwide. Pneumonia is most common at the extremes of life. Predisposing factors in children include an under-developed immune system together with other factors, such as malnutrition and over-crowding. In adults, tobacco smoking is the single most important preventable risk factor. The commonest infecting organisms in children are respiratory viruses and Streptoccocus pneumoniae. In adults, pneumonia can be broadly classified, on the basis of chest radiographic appearance, into lobar pneumonia, bronchopneumonia and pneumonia producing an interstitial pattern. Lobar pneumonia is most commonly associated with community acquired pneumonia, bronchopneumonia with hospital acquired infection and an interstitial pattern with the so called atypical pneumonias, which can be caused by viruses or organisms such as Mycoplasma pneumoniae. Most cases of pneumonia can be managed with chest radiographs as the only form of imaging, but CT can detect pneumonia not visible on the chest radiograph and may be of value, particularly in the hospital setting. Complications of pneumonia include pleural effusion, empyema and lung abscess. The chest radiograph may initially indicate an effusion but ultrasound is more sensitive, allows characterisation in some cases and can guide catheter placement for drainage. CT can also be used to characterise and estimate the extent of pleural disease. Most lung abscesses respond to medical therapy, with surgery and image guided catheter drainage serving as options for those cases who do not respond. PMID:21088086

    Full Text Available BACKGROUND: Arsenic in drinking water was associated with increased risk of all-cause, cancer, and cardiovascular death in adults. However, the extent to which exposure is related to all-cause and deaths from cancer and cardiovascular condition in young age is unknown. Therefore, we prospectively assessed whether long-term and recent arsenic exposures are associated with all-cause and cancer and cardiovascular mortalities in Bangladeshi childhood population. METHODS AND FINDINGS: We assembled a cohort of 58406 children aged 5-18 years from the Health and Demographic Surveillance System of icddrb in Bangladesh and followed during 2003-2010. There were 185 non-accidental deaths registered in-about 0.4 million person-years of observation. We calculated hazard ratios for cause-specific death in relation to exposure at baseline (µg/L, time-weighted lifetime average (µg/L and cumulative concentration (µg-years/L. After adjusting covariates, hazard ratios (HRs for all-cause childhood deaths comparing lifetime average exposure 10-50.0, 50.1-150.0, 150.1-300.0 and ≥300.1µg/L were 1.37 (95% confidence interval [CI], 0.74-2.57, 1.44 (95% CI, 0.88-2.38, 1.22 (95% CI, 0.75-1.98 and 1.88 (95% CI, 1.14-3.10 respectively.

    Full Text Available Background: High mortality and disability due to pneumonia occur worldwide. The introduction of the Integrated Management of Childhood Illness strategy in Malawi brought with it hope of an improvement in the outcome of pneumonia. However, the risk of death and treatment outcomes remain unknown in many districts.Method: The medical records of 466 consecutive patients admitted to the Mchinji District Hospital from January 2004 to January 2006 whose disease met the World Health Organization criteria for pneumonia were reviewed. Data were collected from forms that had been filled out and different treatment outcomes and determinants of death were analysed using logistic regression.Results: Of the 466 patients, 62.7% completed treatment, 15.9% had unknown outcomes, 12.9% died, 8.4% were lost to follow-up, 0.8% failed to improve with treatment, and 0.4% were transferred to other facilities. Independent predictors of death were: age less than 2 years, female sex, history of pneumonia, chest retractions, type of pneumonia, and central cyanosis.Conclusion: A high proportion of deaths and unknown outcomes occurred among participants. Young age, female sex, history of pneumonia, chest retractions and central cyanosis were associated with death. Mortality from pneumonia may be reduced by close monitoring of these risk factors and by improving health education programmes and communicating these findings to parents and health workers. Further investigations of local reasons for high rates of unknown/unreported outcomes are welcomed.

    The paper analyzes the systematic reviews and meta-analyses on the strategic issues of pneumonia, which have been published in the past 3 years. It discusses the prevalence and mortality rates of acquired pneumonia, hospital-acquired (nosocomial) pneumonia, healthcare-associated pneumonia, ventilator-associated pneumonia, and Mycoplasma pneumonia, and the specific features of their etiology, diagnosis, and treatment. A large number of investigations emphasize the relevance of this problem in current clinical practice.

    -terminal provasopressin (copeptin, and C-reactive protein (CRP, as well as Sequential Organ Failure Assessment (SOFA scores, are associated with severity and described as predictors of outcome in ventilator-associated pneumonia (VAP. This study sought to compare the predictive value of these biomarkers for mortality in VAP. METHODS: An observational study of 71 patients with VAP. Levels of procalcitonin, MR-proANP, copeptin, and CRP, together with SOFA scores, were determined at VAP onset, designated day 0 (D0, and on day 4 of treatment (D4. Patients received empirical antimicrobial therapy, with modifications based on culture results. Patients who died before D28 were classified as nonsurvivors. RESULTS: Of the 71 patients evaluated, 45 were classified as survivors. Of the 45 survivors, 35 (77.8% received appropriate antimicrobial therapy, compared with 18 (69.2% of the 26 nonsurvivors (p = 0.57. On D0 and D4, the levels of all biomarkers (except CRP, as well as SOFA scores, were lower in eventual survivors than in eventual nonsurvivors. For D0 and D4, the area under the ROC curve was largest for procalcitonin. On D0, MR-proANP had the highest positive likelihood ratio (2.71 and positive predictive value (0.60, but procalcitonin had the highest negative predictive value (0.87. On D4, procalcitonin had the highest positive likelihood ratio (3.46, the highest positive predictive value (0.66, and the highest negative predictive value (0.93. CONCLUSIONS: The biomarkers procalcitonin, MR-proANP, and copeptin can predict mortality in VAP, as can the SOFA score. Procalcitonin alone has the greatest predictive power for such mortality.

    This one year prospective study was carried out to determine the CBR, CDR and different underfive mortality rates in some selected rural ICDS blocks of West Bengal and also to find out the common causes of infant and childhood mortality in these areas. It was revealed that most of the above mentioned indicators in ICDS blocks were considerably lower than that of National figures, but more or less similar to those of rural Bengal as recorded in routine Govt. reports. Compared to the picture of rural West Bengal, both still birth & perinatal mortality rates were found higher in all ICDS blocks. The causes of mortality trends among under fives' were found similar to that of rural India pattern i.e. prematurity, acute respiratory infections and diarrhoea being the leaders. Neonates, who contributed the largest share of infant mortality died mainly due to prematurity. So, observations like high perinatal mortality & still birth rates, huge proportion of neonatal death during infancy, same IMR but low 5MR, and death of neonates due to prematurity etc. claim the necessity of improving maternal component of ICDS services, their nutritional care in particular.

  19. Cardiovascular diseases mortality following cancer during childhood: long term risk, role of chemotherapy and of radiation dose to heart and brain

    International Nuclear Information System (INIS)

    Full text: Background: A multi-centric French-UK cohort study was performed to evaluate the role of treatment in the long-term overall and cause-specific mortality among childhood cancer survivors. Methods: This study cohort included 4,120 patients treated for a solid tumours before the age of 17 between 1942-1986, in 8 centres in France and UK and who survived at least 5 years from diagnosis. Detailed clinical and therapeutic data were extracted for each patients from medical records. For 2868 of the 2868 patients who received radiotherapy, radiation doses were estimated using DOSEG software at 188 anatomical sites, including heart (7 sites) and lungs (10 sites). We obtained the death causes of 95 % of dead patients. Overall and cause-specific mortality standardized ratios (SMR), absolute excess risk (AER) of death were studied using Poisson regression. Results: 603 patients died during the follow-up, i.e. 8.5-fold (95 % CI: 7.7-9.1) more than that expected in the general population. A total of 32 patients died of cardiovascular diseases, i.e. 4.8-fold (95 % CI, 3.3 to 6.7) more than expected, 21 of which were cardiac diseases, i.e. 6.0-fold more (95% CI, 3.8 to 9.0). Overall, patients who had received radiotherapy had a 5.4-fold (95% CI, 1.5 to 32.1) higher risk of mortality due to cardiovascular disease than those who had not. Mortality due to cardiac disease was related to the administration of alkylating agents and / or vinca alkaloids, and to that of anthracyclines. Each additional 100 mg of anthracyclines per m2 of body surface area increased the mortality rate due to heart diseases by 92% (95% CI, 16% to 318%). Patients who had received between 5 to 14.9 Gy to the heart during radiotherapy had a 14.5-fold (95% CI, 2.0 to 291) higher risk of mortality from cardiac diseases than patients who had not received radiotherapy, this ratio being 32.6 (95% CI, 5.6 to 622) in those who had received more than 15 Gy. Conclusion: Childhood cancer survivors are at high

    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 We carried out a case-control study to investigate risk factors for childhood pneumonia in two groups of 650 children aged under two years in the city of Fortaleza, Ceará, Brazil. The cases were children recruited at the main pediatric hospital with a radiological diagnosis of pneumonia, and controls were children of the same age group recruited from the neighbourhood of the cases. In this paper we focus on variables related to childcare practices. Working mothers, proportion of time the mother had worked since the child was born, and use of day care centers emerged as important risk factors with estimated relative risks of 1.58, 1.76 and 5.22, respectively. Also important were the number of children living in the house and presence of grandparents. However, the presence of siblings under two years and the birth order were not associated with pneumonia. All analysis included adjustment for confounding by income, parents' education, and other risk factors as appropriate. This is the first study from a developing country to identify attendance at day care centers as a risk factor for increased childhood morbidity, in this case pneumonia. This finding is of significant public health importance for countries such as Brazil with growing urban populations and an increasing need by mothers to find work outside the home.Estudou-se o risco de pneumonia nas crianças menores de dois anos na região metropolitana de Fortaleza entre junho/89 e maio/90.

  4. A high burden of respiratory syncytial virus associated pneumonia in children less than two years of age in a South East Asian refugee population.

    Directory of Open Access Journals (Sweden)

    Claudia Turner

    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.

    Objective To determine whether modern treatments for cancer are associated with a net increased or decreased risk of death from neoplastic and non-neoplastic causes among survivors of childhood cancer. Design Population based cohort study. Setting British Childhood Cancer Survivor Study. Participants Nationwide population based cohort of 34 489 five year survivors of childhood cancer with a diagnosis from 1940 to 2006 and followed up until 28 February 2014. Main outcome measures Cause specific standardised mortality ratios and absolute excess risks are reported. Multivariable Poisson regression models were utilised to evaluate the simultaneous effect of risk factors. Likelihood ratio tests were used to test for heterogeneity or trend. Results Overall, 4475 deaths were observed, which was 9.1 (95% confidence interval 8.9 to 9.4) times that expected in the general population, corresponding to 64.2 (95% confidence interval 62.1 to 66.3) excess deaths per 10 000 person years. The number of excess deaths from all causes declined among those treated more recently; those treated during 1990-2006 experienced 30% of the excess number of deaths experienced by those treated before 1970. The corresponding percentages for the decline in excess deaths from recurrence or progression and non-neoplastic causes were 30% and 60%, respectively. Among survivors aged 50-59 years, 41% and 22% of excess deaths were attributable to subsequent primary neoplasms and circulatory conditions, respectively, whereas the corresponding percentages among those aged 60 years or more were 31% and 37%. Conclusions The net effects of changes in cancer treatments, and surveillance and management for late effects, over the period 1940 to 2006 was to reduce the excess number of deaths from both recurrence or progression and non-neoplastic causes among those treated more recently. Among survivors aged 60 years or more, the excess number of deaths from circulatory causes exceeds the excess number

    International Nuclear Information System (INIS)

    Background: Pneumonia is one of the leading causes of morbidity and mortality in children younger than 5 years of age. Zinc may have an important protective role in cases of childhood pneumonia. Objectives: To study the effect of zinc supplementation on duration of hospital stay in children (6 months to 5 years) with pneumonia. Methodology: This Randomized control trial was conducted in the Department of Paediatrics Unit - I, King Edward Medical University / Mayo Hospital, Lahore from January to December 2011. After consent, 150 children from 6 months to 5 years of age with pneumonia consistent with WHO ARI definition along with crepitations on auscultation were registered by non-probability purposive sampling and were randomized into treatment group (Group A) and placebo group (Group B). Seventy five children supplemented with zinc for 14 days while 75 children were supplemented with placebo. Outcome measure was duration of hospital stay. T-test was used to compare the groups. Results: Out of total study population of 150, majority (35%) of children were below 2 years. There was male predominance (64%). Mean duration of hospital stay was significantly reduced in treatment group (p value < 0.05). Conclusion: Zinc supplementation results in statistically significant reduction in the duration of hospital stay in children (6 months to 5 years) with pneumonia. (author)

  10. 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

    Hospital-acquired pneumonia (HAP) and ventilator-associated pneumonia (VAP) are important causes of morbidity and mortality, with mortality rates approaching 62%. HAP and VAP are the second most common cause of nosocomial infection overall, but are the most common cause documented in the intensive care unit setting. In addition, HAP and VAP produce the highest mortality associated with nosocomial infection. As a result, evidence-based guidelines were prepared detailing the epidemiology, micro...

    2015-07-01

    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

    Full Text Available Pneumonia is one of the leading causes of morbidity and mortality in children, mainly in developing countries with a 10–15 times higher mortality rate than developed countries. The aim of the study was to know the mortality rate and its risk factors among under five years old children who were hospitalized due to severe pneumonia. This cross-sectional study was conducted to 1 to 59 months old children with pneumonia at the Department of Pediatric Dr. Hasan Sadikin Bandung Hospital from November 2007 to January 2009. Three hundred and eighteen children were enrolled in this study. The median age was 11.16 months, and 237 (74.5% were ≤12 months of age. Very severe pneumonia was diagnosed in 93 (29.2% and severe pneumonia in 225 (70.8% children. Twenty three (7.2% children died during hospitalization, 20 were hospitalized with very severe pneumonia (p<0.001, OR 20.274, 95%CI: 5.855─70.197. Congenital heart disease (p=0.002, OR 5.795, 95%CI: 2.115–15.407 and leucocytosis (≥15,500/mm3, p=0.002, OR 3.879, 95%CI: 1.547–9.727 were significantly associated to the mortality. Pathogenic bacteria were identified in 11 of 23 patients. In conclusions, the mortality of severe pneumonia is still high. Very severe pneumonia, congenital heart disease and leucocytosis are factors that increase mortality among under-five years old children with pneumonia.

    2011-10-01

    Full Text Available Abstract Background Over thirty years have passed since the Alma-Ata Declaration on primary health care in 1978. Many governments in the first decade following the declaration responded by developing national programmes of community health workers (CHWs, but evaluations of these often demonstrated poor outcomes. As many CHW programmes have responded to the HIV/AIDS pandemic, international interest in them has returned and their role in the response to other diseases should be examined carefully so that lessons can be applied to their new roles. Over half of the deaths in African children under five years of age are due to malaria, diarrhoea and pneumonia - a situation which could be addressed through the use of cheap and effective interventions delivered by CHWs. However, to date there is very little evidence from randomised controlled trials of the impacts of CHW programmes on child mortality in Africa. Evidence from non-randomised controlled studies has not previously been reviewed systematically. Methods We searched databases of published and unpublished studies for RCTs and non-randomised studies evaluating CHW programmes delivering curative treatments, with or without preventive components, for malaria, diarrhoea or pneumonia, in children in sub-Saharan Africa from 1987 to 2007. The impact of these programmes on morbidity or mortality in children under six years of age was reviewed. A descriptive analysis of interventional and contextual factors associated with these impacts was attempted. Results The review identified seven studies evaluating CHWs, delivering a range of interventions. Limited descriptive data on programmes, contexts or process outcomes for these CHW programmes were available. CHWs in national programmes achieved large mortality reductions of 63% and 36% respectively, when insecticide-treated nets and anti-malarial chemoprophylaxis were delivered, in addition to curative interventions. Conclusions CHW programmes could

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

  4. Multi-model inference of adult and childhood leukaemia excess relative risks based on the Japanese A-bomb survivors mortality data (1950-2000).

    Science.gov (United States)

    Walsh, Linda; Kaiser, Jan Christian

    2011-03-01

    Some relatively new issues that augment the usual practice of ignoring model uncertainty, when making inference about parameters of a specific model, are brought to the attention of the radiation protection community here. Nine recently published leukaemia risk models, developed with the Japanese A-bomb epidemiological mortality data, have been included in a model-averaging procedure so that the main conclusions do not depend on just one type of model or statistical test. The models have been centred here at various adult and young ages at exposure, for some short times since exposure, in order to obtain specially computed childhood Excess Relative Risks (ERR) with uncertainties that account for correlations in the fitted parameters associated with the ERR dose-response. The model-averaged ERR at 1 Sv was not found to be statistically significant for attained ages of 7 and 12 years but was statistically significant for attained ages of 17, 22 and 55 years. Consequently, such risks when applied to other situations, such as children in the vicinity of nuclear installations or in estimates of the proportion of childhood leukaemia incidence attributable to background radiation (i.e. low doses for young ages and short times since exposure), are only of very limited value, with uncertainty ranges that include zero risk. For example, assuming a total radiation dose to a 5-year-old child of 10 mSv and applying the model-averaged risk at 10 mSv for a 7-year-old exposed at 2 years of age would result in an ERR=0.33, 95% CI: -0.51 to 1.22. One model (United Nations scientific committee on the effects of atomic radiation report. Volume 1. Annex A: epidemiological studies of radiation and cancer, United Nations, New York, 2006) weighted model-averaged risks of leukaemia most strongly by half of the total unity weighting and is recommended for application in future leukaemia risk assessments that continue to ignore model uncertainty. However, on the basis of the analysis

  5. Intestine-specific Mttp deletion decreases mortality and prevents sepsis-induced intestinal injury in a murine model of Pseudomonas aeruginosa pneumonia.

    Jessica A Dominguez

    Full Text Available BACKGROUND: The small intestine plays a crucial role in the pathophysiology of sepsis and has been referred to as the "motor" of the systemic inflammatory response. One proposed mechanism is that toxic gut-derived lipid factors, transported in mesenteric lymph, induce systemic injury and distant organ failure. However, the pathways involved are yet to be defined and the role of intestinal chylomicron assembly and secretion in transporting these lipid factors is unknown. Here we studied the outcome of sepsis in mice with conditional, intestine-specific deletion of microsomal triglyceride transfer protein (Mttp-IKO, which exhibit a block in chylomicron assembly together with lipid malabsorption. METHODOLOGY/PRINCIPAL FINDINGS: Mttp-IKO mice and controls underwent intratracheal injection with either Pseudomonas aeruginosa or sterile saline. Mttp-IKO mice exhibited decreased seven-day mortality, with 0/20 (0% dying compared to 5/17 (29% control mice (p<0.05. This survival advantage in Mttp-IKO mice, however, was not associated with improvements in pulmonary bacterial clearance or neutrophil infiltration. Rather, Mttp-IKO mice exhibited protection against sepsis-associated decreases in villus length and intestinal proliferation and were also protected against increased intestinal apoptosis, both central features in control septic mice. Serum IL-6 levels, a major predictor of mortality in human and mouse models of sepsis, were elevated 8-fold in septic control mice but remained unaltered in septic Mttp-IKO mice. Serum high density lipoprotein (HDL levels were reduced in septic control mice but were increased in septic Mttp-IKO mice. The decreased levels of HDL were associated with decreased hepatic expression of apolipoprotein A1 in septic control mice. CONCLUSIONS/SIGNIFICANCE: These studies suggest that strategies directed at blocking intestinal chylomicron secretion may attenuate the progression and improve the outcome of sepsis through effects

    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.

    Background Mortality due to severe pneumonia during childhood in resource-constrained settings is high, but data to provide basis for interventions to improve survival are limited. The objective of this study was to determine the risk factors for severe pneumonia in children aged under five years old in Mwanza, Tanzania. Methods We conducted a case-control study of children aged 2 to 59 months at Sekou-Toure regional hospital in Mwanza City, north-western, Tanzania from May 2013 to March 2014. Cases were children with severe pneumonia and controls were children with other illnesses. Data on demography, social-economical status, nutritional status, environmental factors, vaccination status, vitamin A supplementation and deworming, and nasopharyngeal carriage were collected and analysed using logistic regression. Results 117 patients were included in the study. Of these, 45 were cases and 72 controls. Cases were younger than controls, but there were no differences in social-economic or nutritional status between the two groups. In multiple regression, we found that an increased risk of severe pneumonia was associated with cooking indoors (OR 5.5, 95% CI: 1.4, 22.1), and delayed measles vaccination (OR 3.9, 95% CI: 1.1, 14.8). The lack of vitamin A supplementation in the preceding six month and Enterobacter spp nasopharyngeal carriage were not associated with higher risk of severe pneumonia. Age ≥24 months (OR 0.2, 95% CI: 0.04, 0.8) and not receiving antibiotics before referral (OR 0.3, 95% CI 0.1, 0.9) were associated with lower risk for severe pneumonia. Conclusions Indoor air pollution and delayed measles vaccination increase the risk for severe pneumonia among children aged below five years. Interventions to reduce indoor air pollution and to promote timely administration of measles vaccination are urgently needed to reduce the burden of severe pneumonia in children in Tanzania PMID:27508389

    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 Ethiopia childhood mortality has continued to decline although at a swift pace. The drop in urban childhood mortality decline, duration of breastfeeding is the principle reason for the overall decline in mortality trends in Ethiopia. Data from the Ethiopian Demographic and Health Surveys 2000 and 2005 were used. Indirect estimation of Brass and Trussells methods were adopted. Selected demographic and socio-economic variables were included in the analysis with statistically significant effects. Findings clearly show neonatal and post neonatal mortality decline gradually. Even though, Ethiopia childhood mortality rates are still high. The result shows less than 2 years birth interval have higher infant mortality rates than higher birth interval (113 deaths per 1000. The proper spacing of births allows more time for childcare to make more maternal resources available for the care of the child and mother. Therefore, further research is urgent for regional level and national level investigation.

    Abstract Bacteremic pneumonia is usually associated with greater mortality. However, risk factors associated with hospital mortality in bacteremic pneumonia are inadequately described. The study was a retrospective cohort study, conducted in Barnes-Jewish Hospital (2008–2015). For purposes of this investigation, antibiotic susceptibility was determined according to ceftriaxone susceptibility, as ceftriaxone represents the antimicrobial agent most frequently recommended for hospitalized patients with community-acquired pneumonia as opposed to nosocomial pneumonia. Two multivariable analyses were planned: the first model included resistance to ceftriaxone as a variable, whereas the second model included the various antibiotic-resistant species (methicillin-resistant Staphylococcus aureus, Pseudomonas aeruginosa, and Enterobacteriaceae). In all, 1031 consecutive patients with bacteremic pneumonia (mortality 37.1%) were included. The most common pathogens associated with infection were S aureus (34.1%; methicillin resistance 54.0%), Enterobacteriaceae (28.0%), P aeruginosa (10.6%), anaerobic bacteria (7.3%), and Streptococcus pneumoniae (5.6%). Compared with ceftriaxone-susceptible pathogens (46.8%), ceftriaxone-resistant pathogens (53.2%) were significantly more likely to receive inappropriate initial antibiotic treatment (IIAT) (27.9% vs 7.1%; P mechanical ventilation, immune suppression, prior hospitalization, prior antibiotic administration, septic shock, comorbid conditions, and severity of illness. In the second multivariable analysis that included the antibiotic-resistant species, IIAT was still associated with excess mortality, and P aeruginosa infection was identified as an independent predictor of mortality (OR 1.6, 95% CI 1.1–2.2, P = 0.047), whereas infection with ceftriaxone-resistant Enterobacteriaceae (OR 0.6, 95% CI 0.4–1.0, P = 0.050) was associated with lower mortality.

    OBJECTIVE To retrospectively investigate the risk factors associated the mortality of the patients with pneumonia caused by Acinetobacter baumannii and Pseudomonas aeruginosa , and focus on the impact of different antimicrobial regimens on the patients with A. baumannii pneumonia so as to guide the clinical treatment. METHODS We searched the qualified respiratory samples (including sputum and endotracheal aspirate) in the hospital during Jan 2012 to Aug 2012, and identified the cases with A. baumannii and/or P. aeruginosa positive isolates. The clinical data of the cases were reviewed and the cases were recruited when they were clinically diagnosed as pneumonia. The clinical and microbiological data of the patients were collected. logistic regression was applied to identify the risk factors of the mortality. RESULTS Totally 79 patients with pneumonia were enrolled in the study, including 46 patients infected with A. baumannii and 33 patients infected with P. aeruginosa; 29 cases died with the mortality of 36. 7%; the multivariate regression analysis showed that the respiratory frequency, blood urea nitrogen, sepsis, albumin level and use of antibiotics were the independent risk factors for the mortality of the patients with A. baumannii or P. aeruginosa pneumonia. The mortality of the patients with A. baumannii pneumonia was 50. 0% , 18. 8% of the patients with P. aeruginosa pneumonia (P = 0. 004) ; A. baumannii infection was an independent factor for the increase in mortality (OR = 4. 33, P = 0. 007). Of all the A. baumannii strains, the multidrug-resistant A. baumannii accounted for 97. 8%; the analysis of treatment program indicated that the use of single carbapenem for the primary treatment may increase the risk of mortality and that the use of other antibiotics had no significant impact on the mortality. CONCLUSION The severity of infection is the independent risk factor for the mortality of the patients with A. baumannii or P. aeruginosa pneumonia. The

    Compared with community-dwelling persons, residents in long-term care facilities have more functional disabilities and underlying medical illnesses and are at increased risk of acquiring infectious diseases. Pneumonia is the leading cause of morbidity and mortality in this group. Risk factors include unwitnessed aspiration, sedative medication, and comorbidity. Recognition may be delayed because, in this population, pneumonia often presents without fever, cough, or dyspnea. Accurate identification of the etiologic agent is hampered because most patients cannot produce a suitable sputum specimen. It is difficult to distinguish colonization from infection. Colonization by Staphylococcus aureus and gram-negative organisms can result from aspiration of oral or gastric contents, which could lead to pneumonia. Aspiration of gastric contents also can produce aspiration pneumonitis. This condition is not infectious initially and may resolve without antibiotics. Antibiotics for the treatment of pneumonia should cover Streptococcus pneumoniae, Haemophilus influenzae, gram-negative rods, and S. aureus. Acceptable choices include quinolones or an extended-spectrum beta-lactam plus a macrolide. Treatment should last 10 to 14 days. Pneumonia is associated with significant mortality for up to two years. Dementia is related independently to the death rate within the first week after pneumonia, regardless of treatment. Prevention strategies include vaccination against S. pneumoniae and influenza on admission to the care facility. This article focuses on recent recommendations for the recognition of respiratory symptoms and criteria for the designation of probable pneumonia, and provides a guide to hospitalization, antibiotic use, and prevention.

    Full Text Available Abstract Idiopathic chronic eosinophilic pneumonia (ICEP is characterized by subacute or chronic respiratory and general symptoms, alveolar and/or blood eosinophilia, and peripheral pulmonary infiltrates on chest imaging. Eosinophilia is present in most cases, usually in excess of 1000/mm3. In absence of significant blood eosinophilia, a diagnosis of ICEP is supported by the demonstration of bronchoalveolar lavage eosinophilia. ICEP is typically associated with eosinophil counts higher than lymphocyte counts in the bronchoalveolar lavage. ICEP is a rare disorder of unknown cause. Its exact prevalence remains unknown. ICEP may affect every age group but is rare in childhood. It is twice as frequent in women as in men. One third to one half of the ICEP patients have a history of asthma. The mainstay of treatment of ICEP is systemic corticosteroids. Response to oral corticosteroid therapy is dramatic and has led to the consideration of corticosteroid challenge as a diagnostic test for ICEP. Nevertheless, relapses or development of severe asthma are frequent when tapering or withdrawing treatment. Long-term oral corticosteroid therapy is necessary in up to half of the patients.

To examine trends, factors, and mortality of postoperative pneumonia following major cancer surgery (MCS. Methods. From 1999 to 2009, patients undergoing major forms of MCS were identified using the Nationwide Inpatient Sample (NIS, a Healthcare Cost and Utilization Project (HCUP subset, resulting in weighted 2,508,916 patients. Measurements. Determinants were examined using logistic regression analysis adjusted for clustering using generalized estimating equations. Results. From 1999 to 2009, 87,867 patients experienced pneumonia following MCS and prevalence increased by 29.7%. The estimated annual percent change (EAPC of mortality after MCS was −2.4% (95% CI: −2.9 to −2.0, P<0.001; the EAPC of mortality associated with pneumonia after MCS was −2.2% (95% CI: −3.6 to 0.9, P=0.01. Characteristics associated with higher odds of pneumonia included older age, male, comorbidities, nonprivate insurance, lower income, hospital volume, urban, Northeast region, and nonteaching status. Pneumonia conferred a 6.3-fold higher odd of mortality. Conclusions. Increasing prevalence of pneumonia after MCS, associated with stable mortality rates, may result from either increased diagnosis or more stringent coding. We identified characteristics associated with pneumonia after MCS which could help identify at-risk patients in order to reduce pneumonia after MCS, as it greatly increases the odds of mortality.

    OBJECTIVE To explore the drug resistance of Pseudomonas aeruginosa causing pneumonia and the related risk factors for mortality. METHODS This prospective cohort clinical study was conducted in a tertiary surgical intensive care unit (SICU) in Zhongshan Hospital, Fudan University. From Jan 2007 to Dec 2010. a total of 53 patients who underwent endotracheal intubation and ventilated for more than 48 hours and were with positive culture of P. aeruginosa were enrolled in this study; the drug susceptibility testing was performed by KB method. The vital signs, ventilation parameters, treatment regiments of the patients were recorded, the follow-up of the mortality within 28 days was carried out. RESULTS Of 8 commonly used antibiotics against P. aeruginosa, amikacin was with the lowest resistance rate of 15. 1%, followed by cefoperazone/sulbactam, meropenem, ceftazidime, cefepime, and imipenem) the resistance rate to piperacillin/tazobactam was the highest (47. 2%), the multidrug-resistant rate was 32.1% ; of 53 patients, 17 patients died and 11 patients died within 28 days; the drug resistance rates of P. aeruginosa to piperacillin/tazobactam and imipenem and the multidrug-resistance rate were much higher in death group than in the survival group (76. 5% vs 33. 3%, 58. 8% vs 27. 8%, and 58. 8% vs. 19.4%, respectively) (P<0. 05). There was significant difference between survivors and non-survivors for age (75. 5 vs 56. 0 respectively) (P<0. 05); of the patients in the death group, the survival days of the patients resistant to imipenem were less than those of the patients without imipenem-resistance (P=0. 025) ; multivariate logistic regression analysis showed that there was significant correlation between the age, duration of mechanical ventilation, multidrug-resistance of P. aeruginosa, resistance to piperacillin/tazobactam and the mortality.

    2014-06-01

    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.

    Bighorn sheep mortality related to pneumonia is a primary factor limiting population recovery across western North America, but management has been constrained by an incomplete understanding of the disease. We analysed patterns of pneumonia-caused mortality over 14 years in 16 interconnected bighorn sheep populations to gain insights into underlying disease processes. 2. We observed four age-structured classes of annual pneumonia mortality patterns: all-age, lamb-only, secondary all-age and adult-only. Although there was considerable variability within classes, overall they differed in persistence within and impact on populations. Years with pneumonia-induced mortality occurring simultaneously across age classes (i.e. all-age) appeared to be a consequence of pathogen invasion into a naïve population and resulted in immediate population declines. Subsequently, low recruitment due to frequent high mortality outbreaks in lambs, probably due to association with chronically infected ewes, posed a significant obstacle to population recovery. Secondary all-age events occurred in previously exposed populations when outbreaks in lambs were followed by lower rates of pneumonia-induced mortality in adults. Infrequent pneumonia events restricted to adults were usually of short duration with low mortality. 3. Acute pneumonia-induced mortality in adults was concentrated in fall and early winter around the breeding season when rams are more mobile and the sexes commingle. In contrast, mortality restricted to lambs peaked in summer when ewes and lambs were concentrated in nursery groups. 4. We detected weak synchrony in adult pneumonia between adjacent populations, but found no evidence for landscape-scale extrinsic variables as drivers of disease. 5. We demonstrate that there was a >60% probability of a disease event each year following pneumonia invasion into bighorn sheep populations. Healthy years also occurred periodically, and understanding the factors driving these

    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. PMID:26498896

    In the United States in the 1930s, although the pathogen was not known, atypical pneumonia was clinically distinguished from pneumococcal pneumonia by its resistance to sulfonamides. Reimann (1938) reported seven patients with an unusual form of tracheo bronchopneumonia and severe constitutional symptoms. He believed the clinical picture of this disease differed from that of the disease caused by influenza viruses or known bacteria and instead suspected "primary atypical pneumonia." For many years, the responsible infectious agent was tentatively classified as a filterable virus that could pass through a Seitz filter to remove bacteria and was reported to be a psittacosis-like or new virus. After that, Eaton et al. (1942, 1944, 1945) identified an agent that was the principal cause of primary atypical pneumonia using cotton rats, hamsters, and chick embryos. Eaton et al. (1942, 1944, 1945) did not perform an inoculation study in human volunteers. During the 1940s, there were three groups engaged in discovering the etiology of the primary atypical pneumonia. (1) Commission on Acute Respiratory Diseases Diseases directed by John Dingle, (2) Dr. Monroe Eaton's group, the Virus Research Laboratory of the California State Public Health Department, (3) The Hospital of the Rockefeller Institute for Medical Research directed by Horsfall. During 1940s, the members of the Commission on Acute Respiratory Diseases concluded that the bacteria-free filtrates obtained from the patients, presumably containing a virus, could induce primary atypical pneumonia in human volunteers via Pinehurst trials. During 1950s, serological approaches for identification of the Eaton agent developed such as Fluorescent-Stainable Antibody, and at the beginning of the1960s, the Eaton agent successfully grew in media, and finally accepted as a cause of primary atypical pneumonia. Thus, technical difficulties with visualizing the agent and failure to recognize the full significance of the Pinehurst

    Viruses, particularly syncitial respiratory virus, are the main aetiology of community-acquired lower respiratory tract infections in infants, while bacterial agents are more frequently responsible in children older than 3 years. Antimicrobial therapy must take into account the development of reduced susceptibility of penicillin to strains of Streptoccocus pneumoniae and Haemophilus influenzae with beta-lactamase, and high frequency of Mycoplasma pneumoniae and Chlamydia pneumoniae infections. Although the mortality rate has remained low in France, the morbidity appeared to increase in recent years. PMID:10223154

    2014-01-01

    Background Mycoplasma pneumoniae (MP) pneumonia is a self-limiting disease, but some patients complain of progressive pneumonia, despite of appropriate antibiotic treatment. We aimed to introduce the role of immune-modulators (corticosteroid and/or intravenous immunoglobulin, IVIG) treatment for childhood MP pneumonia based on previous our experiences. Materials and Methods A retrospective case series analysis for 183 children with MP pneumonia was performed. MP pneumonia patients were diagnosed by two Immunoglobulin M (IgM) tests: the micro-particle agglutination method (≥1:40) and the cold agglutination test (≥1:4), and were examined twice at the initial admission and at discharge. Among 183 MP pneumonia patients, 90 patients with persistent fever for over 48 hours after admission or those with severe respiratory symptoms and signs received additional prednisolone (82 patients, 1 mg/kg/day) or intravenous methylprednisolone (8 patients, 5-10 mg/kg/day) with antibiotics. Four patients with aggravated clinical symptoms and chest radiographic findings after corticosteroid treatment received IVIG (1 g/kg/day, 1-2 doses). Results Mean age of 183 patients was 5.5 ± 3.2 years (6 months-15 years), and the male: female ratio was 1.1:1 (96:87). Fifty-seven patients (31%) were seroconverters and 126 seropositive patients showed increased diagnostic IgM antibody titres during admission (over 4 folds). The majority of the patients who received corticosteroids (86/90 cases) showed rapid defervescence within 48 hours with improved clinical symptoms, regardless of the used antibiotics. Also, 4 patients who received additional IVIG improved both clinically and radiographically within 2 days without adverse reaction. Conclusions In the era of macrolide-resistant MP strains, early additional immune-modulator therapy with antibiotics might prevent from the disease progression and reduce the disease morbidity without adverse reaction.

    Full Text Available Pneumonia is the leading cause of infectious death amongst children globally, with the highest burden in Africa. Early identification of children at risk of treatment failure in the community and prompt referral could lower mortality. A number of clinical markers have been independently associated with oral antibiotic failure in childhood pneumonia. This study aimed to develop a prognostic model for fast-breathing pneumonia treatment failure in sub-Saharan Africa.We prospectively followed a cohort of children (2-59 months, diagnosed by community health workers with fast-breathing pneumonia using World Health Organisation (WHO integrated community case management guidelines. Cases were followed at days 5 and 14 by study data collectors, who assessed a range of pre-determined clinical features for treatment outcome. We built the prognostic model using eight pre-defined parameters, using multivariable logistic regression, validated through bootstrapping.We assessed 1,542 cases of which 769 were included (32% ineligible; 19% defaulted. The treatment failure rate was 15% at day 5 and relapse was 4% at day 14. Concurrent malaria diagnosis (OR: 1.62; 95% CI: 1.06, 2.47 and moderate malnutrition (OR: 1.88; 95% CI: 1.09, 3.26 were associated with treatment failure. The model demonstrated poor calibration and discrimination (c-statistic: 0.56.This study suggests that it may be difficult to create a pragmatic community-level prognostic child pneumonia tool based solely on clinical markers and pulse oximetry in an HIV and malaria endemic setting. Further work is needed to identify more accurate and reliable referral algorithms that remain feasible for use by community health workers.

    International Nuclear Information System (INIS)

    Serologically proven 21 patients with Mycoplasma pneumoniae pneumonia that showed infiltrative shadows on chest radiograms were studied by computed tomography (CT). Localization of the lesion and the fashion of its progression through the lung were analyzed. Following 3 loci were defined on the basis of the investigations of critical analysis of the chest radiograms, and of radiopathological analysis of the experimental animal model of mycoplasmal pneumonia with soft X-ray image. I: Peribronchial and periarterial interstitium. II: Bronchiole and its surroundings. III: Lung parenchyma, on hilar area as IIIh, on marginal area as IIIm. Even in the early phase of this disease, radiopathological findings on CT have been distributed in all loci mentioned above. The Shadow disappeared from locus III approximately 14th day from the onset. The shadow have remained, however, loci I, II for a long period. Those findings suggest that locus I and II are one of the major focus of Mycoplasma neumoniae pneumonia. Volume loss in the locus III was observed 78 % of the cases at 28th day from the onset. The shadow on locus IIIh was more prominent than locus IIIm. Reported analytical method with CT could be widely applied to disclose a radiopathological details in other infectious diseases of the lung. (author)

    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.

    Full Text Available Klebsiella peumoniae, a capsulated gram negative bacillus is responsible for causing life threatening infections in humans. Carbapenems are the drug of choice for serious infection caused by multidrug resistant Klebsiella pneumoniae. The emergence of carbapenem resistance has made it extremely difficult to treat such infections resulting in significant morbidity and mortality. Aims: To study the prevalence of carbapenem resistance using ertapenem as a marker and to detect Klebsiella pneumoniae Carbapenemase (KPC producing Klebsiella pneumoniae as a mechanism of resistance. Material and Methods: The study included 102 patients from which Klebsiella pneumoniae isolated. Identification and antibiotic susceptibility testing of Klebsiella pneumoniae was performed on miniAPI (Analytical Profile Index, Semiautomated bacterial identification system according to Clinical and Laboratory Standards Institute (CLSI guidelines of 2011. The modified Hodge test was performed for detection of Carbapenemase production. Patient’s clinical and demographic details along with risk factors and co-morbid conditions, type of response to antimicrobial therapy and mortality were collected. Results: The prevalence of carbapenem resistance was found to be 30.41% with 16.6% KPC producing Klebsiella pneumoniae. The co-morbid conditions like immunocompromised state (p =0.042, prior antibiotics therapy (p=0.047, previous hospitalization (p =0.021, intensive care unit stay (p=0.047 and use of indwelling devices (p =0.013 were found to be significantly associated with carbapenem resistance.

    Abstract Objective: In the antibiotic era, purulent pericarditis is a rare entity. However, there are still reports of cases of the disease, which is associated with high mortality, and most such cases are attributed to delayed diagnosis. Approximately 40-50% of all cases of purulent pericarditis are caused by Gram-positive bacteria, Streptococcus pneumoniae in particular. Methods: We report four cases of pneumococcal pneumonia complicated by pericarditis, with different clinical features and levels of severity. Results: In three of the four cases, the main complication was cardiac tamponade. Microbiological screening (urinary antigen testing and pleural fluid culture) confirmed the diagnosis of severe pneumococcal pneumonia complicated by purulent pericarditis. Conclusions: In cases of pneumococcal pneumonia complicated by pericarditis, early diagnosis is of paramount importance to avoid severe hemodynamic compromise. The complications of acute pericarditis appear early in the clinical course of the infection. The most serious complications are cardiac tamponade and its consequences. Antibiotic therapy combined with pericardiocentesis drastically reduces the mortality associated with purulent pericarditis. PMID:26398760

    Full Text Available : BACKGROUND: Most of the times, a Community Acquired Pneumonia (CAP patient is being treated with empirical antibiotics by best guess method by the clinician. Patient who did not show expected clinical improvement or resolution on chest x- ray after 2 weeks of antibiotics is considered as unresolved or non-resolving pneumonia and is a major problem, contributing to increased mortality and morbidity in the medical wards. AIM OF STUDY: 1.Tostudy the clinical profile of unresolved pneumonia among CAP. 2. To know the treatment outcome in these cases. MATERIALS & METHODS: 80 hospitalized CAP patients who did not improve either clinically or radiologically after 2 weeks of broad spectrum antibiotics were included in the study. Details of these patients including investigations done at other higher centers were recorded and patients were followed up for 6 months or till death. RESULTS: Unresolved pneumonia was commonly observed in patients more than 50 years. Pulmonary tuberculosis was the commonest cause, followed by MDR varieties of CAP, Bronchogenic carcinoma. Multiple risk factors were noted, which includes cigarette smoking, alcohol, COPD, Diabetes, HIV positive status. Elderly age, multiple risk factors, antibiotic abuse and resistance resulted in majority of the cases. CONCLUSION: This study highlights the importance of early recognition and appropriate treatment of CAP to prevent unresolved pneumonia and use of invasive and latest investigations to recognize unresolved pneumonia, to decrease mortality and morbidity.

  10. Hemorrhagic pneumonia in mink caused by Pseudomonas aeruginosa

    DEFF Research Database (Denmark)

    Salomonsen, Charlotte Mark

    Hemorrhagic pneumonia in mink is an acute and fatal disease caused by Pseudomonas aeruginosa. The mink are typically found dead without prior clinical symptoms. The disease can be highly contagious and varying mortalities on the farm level has been reported. Hemorrhagic pneumonia in mink...... is seasonal with outbreaks almost exclusively occurring from September to November in Denmark. In human medicine, P. aeruginosa is regarded as a pathogen for immune compromised individuals but no underlying disease or immune defect has been identified in mink dying of hemorrhagic pneumonia. In fact, little...... research has been performed in this field and most published work is more than 25 years old. The studies presented in this thesis aim at elucidating varying aspects of the disease: Article I investigates the relationships of P. aeruginosa isolated from mink hemorrhagic pneumonia using pulsed field gel...

    Bacterial pneumonia is a major cause of morbidity and mortality in elderly. We hypothesize that dysbiosis between regular residents of the upper respiratory tract (URT) microbiome, that is balance between commensals and potential pathogens, is involved in pathogen overgrowth and consequently disease. We compared oropharyngeal microbiota of elderly pneumonia patients (n=100) with healthy elderly (n=91) by 16S-rRNA-based sequencing and verified our findings in young adult pneumonia patients (n=27) and young healthy adults (n=187). Microbiota profiles differed significantly between elderly pneumonia patients and healthy elderly (PERMANOVA, Pdisease was less clear. A decision tree model based on the relative abundance of five bacterial community members in URT microbiota showed high specificity of 95% and sensitivity of 84% (89% and 73%, respectively, after cross-validation) for differentiating pneumonia patients from healthy individuals. These results suggest that pneumonia in elderly and young adults is associated with dysbiosis of the URT microbiome with bacterial overgrowth of single species and absence of distinct anaerobic bacteria. Whether the observed microbiome changes are a cause or a consequence of the development of pneumonia or merely coincide with disease status remains a question for future research.

    2015-01-01

    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.

    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.

  19. Pre-treatment ferritin level and alveolar-arterial oxygen gradient can predict mortality rate due to acute/subacute interstitial pneumonia in dermatomyositis treated by cyclosporine a/glucocorticosteroid combination therapy: a case control study [corrected].

    Directory of Open Access Journals (Sweden)

    Kentaro Isoda

    Full Text Available BACKGROUND: Acute/subacute interstitial pneumonia in dermatomyositis (DM-A/SIP is a disease associated with a poor prognosis that resists treatment with glucocorticosteroids (GC and progresses rapidly in a period of weeks to months to death. We retrospectively studied outcomes, prognostic factors, and their relations with survival rate in patients with DM-A/SIP treated with early cyclosporine A (CSA/GC combination therapy and 2-hour postdose blood concentration monitoring. METHODS: This study comprised 32 DM-A/SIP patients who were simultaneously treated with CSA and prednisolone. Clinical and laboratory findings were compared between those who died due to DM-A/SIP and those surviving 24 weeks after beginning of therapy. Prognostic factors were extracted, and their relations with the survival rate were evaluated. RESULTS: Of the 32 DM-A/SIP patients, 25 survived, 5 died of DM-A/SIP, and 2 died of infections. In those who died due to DM-A/SIP, ferritin level and the alveolar-arterial oxygen gradient were significantly increased compared with the survivors (P<0.001 and P = 0.002, respectively. Multivariate analyses showed that ferritin and alveolar-arterial oxygen gradient were independent prognostic factors of poor outcome. The survival rate 24 weeks after beginning of treatment was significantly lower in those with a ferritin level of ≥ 600 ng/ml and alveolar-arterial oxygen gradient of ≥ 45 Torr (P<0.001 and P<0.001, respectively. All patients with both prognostic factors died, and the outcome was significantly poorer in these patients than in those with one or neither of the prognostic factors (P<0.001. CONCLUSIONS: We identified pre-treatment high serum ferritin level and high alveolar-arterial oxygen gradient as poor prognostic factors in DM-A/SIP patients undergoing early CSA/GC combination therapy and showed that the outcomes were poor in patients with both factors.

    Full Text Available The objective of this study was to describe the epidemiology, clinical characteristics, microbiology and outcomes of patients of all ages with Streptococcus pneumoniae meningitis between 2000 and 2004; two years pre- and postintroduction of an S pneumoniae 7-valent conjugate vaccine program in Alberta in children younger than two years of age. The high mortality rate associated with S pneumoniae meningitis, despite appropriate therapy, suggests that prevention of S pneumoniae meningitis is critical. Despite implementation of a PCV-7 program in Alberta, rates of S pneumoniae meningitis in children younger than two years of age is still high. Thus, continued research into safe and efficacious vaccines covering a broader range of S pneumoniae serotypes is necessary.

  3. 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.

    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.

    International Nuclear Information System (INIS)

    In order to identify and classify the basic CT appearance of interstitial pneumonia, radiologic-pathologic correlative study was performed using inflated and fixed lungs from autopsy and surgery. The patterns of the abnormalities on the CT images of interstitial pneumonia were classified into 7 categories. Important pathological changes which affected the CT images were alveolar collapse and airway dilatation. Based on the result of above study, we analyzed CT of 22 patients with IIP. The lesions which were classified into a hazy density, micronodular densities, confluence of various sized ring like shadows and subpleural bullous changes were frequently recognized together mostly in the periphery of the lung.

    Community acquired pneumonia (CAP) is an acute respiratory infection that affects pulmonary parenchyma, and is caused by community acquired microorganisms. In Chile, pneumonia represents the main cause of death due to infectious diseases and is the third specific cause of mortality in adults. In 1999, an experts committee in representation of "Sociedad Chilena de Enfermedades Respiratorias", presented the first National Guidelines for the Treatment of Adult Community Acquired Pneumonia, mainly based in foreign experience and documents, and adapted it to our National Health System Organization. During the last decade, impressive epidemiological and technological changes have occurred, making the update of guidelines for treatment of NAC by several international scientific societies, necessary. These changes include: new respiratory pathogens that are being identified in CAP and affect adult patients (Mycoplasma pneumoniae, Chlamydia pneumoniae, Legionella pneumophila); the increasing senescent adult population that carries multiple co-morbidities; the emergence of antimicrobial resistance among respiratory pathogens associated to massive antibiotic prescription; the development by the pharmaceutical industry of new drugs that are effective for pneumonia treatment (macrolides, ketolides and respiratory fluorquinolones); and the development of new diagnostic techniques for detection of antigens, antibodies, and bacterial DNA by molecular biology, useful in respiratory infections. Based on these antecedents, an Advisory Committee of "Sociedad Chilena de Enfermedades Respiratorias" and "Sociedad Chilena de Infectología" has reviewed the national and international evidence about CAP management in adults in order to update clinical recommendations for our country.

A total of 15 published articles and 13 congress abstracts were included in the analysis. In children vaccine-type and any-type invasive pneumococcal disease (including decreases in pneumococcal meningitis morbidity and mortality), on pneumonia incidence and mortality, and on otitis media. Nasopharyngeal carriage of vaccine-type and any-type pneumococci decreased after the primary doses, with no early signs of replacement with other pathogens. Finally, herd protection against vaccine-type invasive pneumococcal disease and pneumonia in unvaccinated subjects was shown in some studies for some age groups. In conclusion, pneumococcal disease decreased after the introduction of PHiD-CV into the Brazilian national immunization program. Further follow-up is needed to evaluate the long-term overall impact of PHiD-CV in the Brazilian population. PMID:27113162

  14. Comparison between pandemic H1N1 2009 influenza pneumonia and seasonal influenza pneumonia in adults

    International Nuclear Information System (INIS)

    We compared 126 cases of seasonal influenza pneumonia (seasonal flu) reported between January, 1996 and March, 2009, with 10 cases of laboratory-confirmed pandemic influenza (H1N1) 2009 influenza virus pneumonia (novel flu), based on clinical condition, computed tomography (CT) findings, severity, treatment, and prognosis, to clarify the characteristics of this novel flu. The mean age of subjects was 52.4 years in the novel flu group and 64 years in the seasonal flu group, and novel flu patients were younger than seasonal flu patients. Seasonal flu patients had more underlying diseases than did novel flu patients. The median duration from illness onset to hospitalization was 4 days in both groups. Primary viral pneumonia was present in 70% of novel flu cases and 31% of seasonal flu cases. The proportion of primary virus pneumonia was higher in novel flu patients, and the disease severity of the seasonal flu group was more severe than that of the novel flu group. White blood cell and lymphocyte counts were lower in novel flu patients, and chest CT images showed bilateral shadows and pure ground-glass opacities more frequently in the novel flu cases. There were no differences in treatment, number of days required for the fever to subside, or mortality between the groups. (author)

    Manal Tadros

    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.

    International Nuclear Information System (INIS)

    Exogenous lipid pneumonia (ELP) is caused by the aspiration of animal, vegetal or, more often, mineral oils. Even though it may also be acute, ELP is most frequently a chronic disease, affecting people with predisposing factors, such as neuromuscular disorders, structural abnormalities and so on; very often exogenous lipid pneumonia is found in tracheotomized patients. The pathology of lipid pneumonia is a chronic inflammatory process evolving in foreign-body-like reaction, and eventually in ''end-stage lung'' condition. Clinically, most patients are asymptomatic; few cases only present with cough, dyspnea and chest pain. Eight cases of ELP, studied over the past 3 years, are described in this paper. All the patients were examined by chest radiographs and standard tomograms; 3 patients underwent CT. X-ray features were mono/bilateral consolidation of the lower zones, with air bronchogram and variable reduction in volume. CT density was not specific for fat tissue. In all cases the diagnosis was confirmed at biopsy. In 5 patients, followed for at least one year, clinical-radiological features showed no change. Thus, complications of ELP (especially malignant evolution) could be excluded. The authors conclude that lipid pneumonia must be considered in differential diagnosis of patients with history of usage of oils and compatible X-ray findings. The usefulness of an accurate follow-up is stressed

  20. Lipoid pneumonia: an overview.

    Science.gov (United States)

    Hadda, Vijay; Khilnani, Gopi C

    Lipoid pneumonia is an uncommon disease caused by the presence of lipid in the alveoli. It is classified into two major groups, depending on whether the lipid/oil in the respiratory tract is from an exogenous (exogenous lipoid pneumonia) or endogenous/idiopathic (endogenous lipoid pneumonia) source. The usual presentation occurs with insidious onset and nonspecific respiratory symptoms such as dyspnea and/or cough. The main radiological findings include airspace consolidations, ground-glass attenuation, airspace nodules and 'crazy-paving' pattern. However, the radiological appearance of the disorder can mimic many other lung diseases, including carcinoma. Owing to the nonspecific clinical presentation and radiological features, the diagnosis is often missed or delayed. Pathologically, lipoid pneumonia is a chronic foreign body reaction to fat, characterized by lipid-laden macrophages. Diagnosis of this disease requires a high index of suspicion and can be confirmed by demonstration of lipid-laden macrophages in respiratory samples such as sputum, bronchoalveolar lavage fluid or fine-needle aspiration cytology/biopsy from lung lesions. Treatment protocols for this illness are poorly defined. PMID:21128754

    2015-03-01

    Full Text Available Background Pneumonia is a major cause of morbidity and mortality in children under five years of age. Pneumonia can be of bacterial or viral origin. It is difficult to distinguish between these two agents based on clinical manifestations, as well as radiological and laboratory examinations. Furthermore, bacterial cultures take time to incubate and positive results may only be found in 10-30% of bacterial pneumonia cases. Procalcitonin has been used as a marker to distinguish etiologies, as bacterial infections tend to increase serum procalcitonin levels. Objective To determine the sensitivity, specificity, positive predictive value and negative predictive value of procalcitonin in community-acquired bacterial pneumonia. Method This cross-sectional study was conducted in the Pediatric Health Department of Dr. M. Djamil Hospital, Padang. Subjects were selected by consecutive sampling. Procalcitonin measurements and PCR screening were performed on blood specimens from 32 pneumonia patients and compared. Results Of the 32 subjects, most were boys (56.25%, under 5 years of age (99%, and had poor nutritional status (68.75%. Using a cut-off point of 0.25 ng/mL, procalcitonin level had a sensitivity of 92%, specificity 50%, positive predictive value 88%, and negative predictive value 60% for diagnosing bacterial pneumonia. Using a cut-off point of 0.5 ng/mL, procalcitonin level had a specificity of 46%, specificity 83%, positive predictive value 91%, and negative predictive value 25%. Conclusion A cut-off point of 0.25 ng/mL of procalcitonin level may be more useful to screen for bacterial pneumonia than a cut-off point of 0.5 ng / mL. However, if the 0.25 ng/mL cut-off point is used, careful monitoring will be required for negative results, as up to 40% may actually have bacterial pneumonia. [Paediatr Indones. 2015;55:65-9.].

  3. Mycoplasma pneumoniae pneumonia: CT features in 16 patients

    International Nuclear Information System (INIS)

    The objective of this study was to assess the computed tomography (CT) features of Mycoplasma pneumoniae pneumonia. We retrospectively reviewed CT findings of 16 patients (M:F=9:7, age range 1-74 years, median 9 years) with serologically proven Mycoplasma pneumoniae pneumonia and with chest CT scan available. Two distinctive patterns of CT features of M. pneumoniae pneumonia were noted between the paediatric (age <18 years) and the adult (age ≥18 years) groups. The pediatric group (n=11) showed lobar or segmental consolidation (100%) with frequent pleural effusion (82%) and regional lymphadenopathy (82%) and mild volume decrease of the involved lobe (73%), while four of the five adult patients showed diffuse and/or multifocal, centrilobular or peribronchovascular areas of ground-glass attenuation (80%) with a lobular distribution, and frequent thickening of interlobular septa (60%) and the bronchial walls (40%) were also detected at high-resolution CT. The CT finding of a lobar or segmental consolidation with a parapneumonic effusion seen in our children with M. pneumoniae pneumonia was similar to that of bacterial lobar pneumonia. In contrast, the CT findings noted in our adult patients consisted of a mixture of a bacterial bronchopneumonia pattern and a viral interstitial pneumonia pattern. (orig.)

    Full Text Available Mycoplasma pneumoniae (Mp sometimes causes immunological complications in children. We present a rare case of hemophagocytic syndrome (HPS caused by Mp in a previously healthy 7-year-old Japanese girl. A chest radiograph obtained to evaluate the source of her fever showed infiltration in the lower right lung with mild splenomegaly. We could diagnose the patient with HPS on the basis of the hemophagocytic-lymphohistiocytosis- (HLH 2004 criteria. She met the criteria for fever, splenomegaly, neutrophil count (265 mg/dL, and ferritin level (>500 ng/mL. Furthermore, a peripheral blood smear showed an increased number of monocytes/macrophages with erythrophagocytosis. Treatment with clarithromycin and prednisolone, which was initiated soon after the diagnosis, was successful. Mp infection might partly progress to HPS in certain conditions. Clinicians should be aware of HPS caused by Mp and start appropriate treatment as soon as possible if the disease is suspected.

    Full Text Available Aim: Ventilator-associated pneumonia (VAP is the infection that is an important cause of morbidity and mortality developed in patients whom the invasive mechanical ventilation (MV were performed in intensive care units (ICU. In this study, the factors of VAP developing in patients whom the mechanical ventilation of ICU performed, antibiotic susceptibility to these factors and determining the risk factors were aimed. Material and Method: Between January 2009 and March 2013, 79 cases, followed with the mechanical ventilation for at least for 48 hours and developed VAP, were retrospectively reviewed at Anesthesiology and Intensive Care Unit of Reanimation at Faculty of Medicine at Yuzuncu Yil University, performing endotracheal intubation. The cases were evaluated in terms of microorganisms, antibiotic susceptibility and risk factors. Results: The rate of our VAP speed was calculated to be 19.68 on the day of 1000 ventilator. While a single microorganism could be isolated in 81.1% of the 74 VAP cases whose the active pathogen could be isolated, two or more than two microorganisms were isolated in 18.9% of them.While 83 of the strains (90.2% were gram-negative bacteria, 7 of them (7.6% were gram-positive bacteria. Acinetobacter spp. (40.2% was most commonly isolated as a gram-negative factor, but methicillin-resistant S. aureus (4.3% was isolated as a gram-positive factor. It was determined that the isolated factors in VAP cases were significantly resistant to the broad-spectrum antibiotics. Discussion: As a result, in patients with high-risk factors for the development of VAP, early and appropriate empirical antibiotic treatment should be started according to the results of the sensitivity of the unit and for the multi-drug-resistant microorganisms with common and high mortality.

    Full Text Available Background: Chickenpox is a very contagious viral disease that caused by varicella-zoster virus, which appears in the first week of life secondary to transplacental transmission of infection from the affected mother. When mother catches the disease five days before and up to two days after the delivery, the chance of varicella in neonate in first week of life is 17%. A generalized papulovesicular lesion is the most common clinical feature. Respiratory involvement may lead to giant cell pneumonia and respiratory failure. The mortality rate is up to 30% in the case of no treatment, often due to pneumonia. Treatment includes hospitalization, isolation and administration of intravenous acyclovir. The aim of this case report is to introduce the exogenous surfactant replacement therapy after intubation and mechanical ventilation for respiratory failure in neonatal chickenpox pneumonia and respiratory distress. Case Presentation: A seven-day-old neonate boy was admitted to the Neonatal Intensive Care Unit at Amirkola Children’s Hospital, Babol, north of Iran, with generalized papulovesicular lesions and respiratory distress. His mother has had a history of Varicella 4 days before delivery. He was isolated and given supportive care, intravenous acyclovir and antibiotics. On the second day, he was intubated and connected to mechanical ventilator due to severe pneumonia and respiratory failure. Because of sever pulmonary involvement evidenced by Chest X-Ray and high ventilators set-up requirement, intratracheal surfactant was administered in two doses separated by 12 hours. He was discharged after 14 days without any complication with good general condition. Conclusion: Exogenous surfactant replacement therapy can be useful as an adjunctive therapy for the treatment of respiratory failure due to neonatal chickenpox.

    Hospital-acquired pneumonia (HAP) is a frequent cause of nosocomial infections, responsible for great morbidity and mortality worldwide. The majority of studies on HAP have been conducted in patients hospitalized in the intensive care unit (ICU), as mechanical ventilation represents a major risk factor for nosocomial pneumonia and specifically for ventilator-associated pneumonia. However, epidemiological data seem to be different between patients acquiring HAP in the ICU vs. general wards, suggesting the importance of identifying non ICU-acquired pneumonia (NIAP) as a clinical distinct entity in terms of both etiology and management. Early detection of NIAP, along with an individualized management, is needed to reduce antibiotic use and side effects, bacterial resistance and mortality. The present article reviews the pathophysiology, diagnosis, treatment and prevention of NIAP. PMID:26927074

    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.

    Full Text Available Hospital-acquired pneumonia (HAP and ventilator-associated pneumonia (VAP are important causes of morbidity and mortality, with mortality rates approaching 62%. HAP and VAP are the second most common cause of nosocomial infection overall, but are the most common cause documented in the intensive care unit setting. In addition, HAP and VAP produce the highest mortality associated with nosocomial infection. As a result, evidence-based guidelines were prepared detailing the epidemiology, microbial etiology, risk factors and clinical manifestations of HAP and VAP. Furthermore, an approach based on the available data, expert opinion and current practice for the provision of care within the Canadian health care system was used to determine risk stratification schemas to enable appropriate diagnosis, antimicrobial management and nonantimicrobial management of HAP and VAP. Finally, prevention and risk-reduction strategies to reduce the risk of acquiring these infections were collated. Future initiatives to enhance more rapid diagnosis and to effect better treatment for resistant pathogens are necessary to reduce morbidity and improve survival.

    This report reviews the pulmonary and extrapulmonary manifestation of infections due to Coxiella burnetii. Q fever, a zoonosis, is due to infection with C. burnetii. This spore-forming microorganism is a small gram-negative coccobacillus that is an obligate intracellular parasite. The most common animal reservoirs are goats, cattle, sheep, cats, and occasionally dogs. The organism reaches high concentrations in the placenta of infected animals. Aerosolisation occurs at the time of parturition and infection follows inhalation of this aerosol. There are three distinct clinical syndromes of the acute form of the illness: nonspecific febrile illness, pneumonia, and hepatitis. The chronic form of Q fever is almost always endocarditis, but occasionally it is manifest as hepatitis, osteomyelitis or endovascular infection. The pneumonic form of the illness can range from very mild-to-severe pneumonia requiring assisted ventilation. Multiple round opacities are a common finding on chest radiography. Treatment with doxycycline or a fluoroquinolone is preferred. Susceptibility to macrolides is variable. In conclusion, Coxiella burnetii pneumonia should be considered when there is a suitable exposure history and when outbreaks of a pneumonic illness are being investigated. PMID:12762362

    Full Text Available Abstract Background Pneumococcal diseases remain a major cause of morbidity and mortality worldwide. Updated data on drug-resistance from different populations may be important to recognize changes in disease patterns. This study assessed current levels of penicilin resistance among Streptococcus Pneumoniae causing pneumonia in Spanish middle age and older adults. Methods Antimicrobial susceptibility was tested for 104 consecutive isolates of Streptococcus pneumoniae recovered from patients 50 years or older with radiographically confirmed pneumonia in the region of Tarragona (Spain between 2002 and 2007. According to the minimum inhibitory concentration of tested antimicrobials (penicillin, erythromycin, cefotaxime and levofloxacin strains were classified as susceptible or resistant. Antimicrobial resistance was determined for early cases (2002–2004 and contemporary cases (2005–2007. Results Twenty-seven (25.9% were penicillin-resistant strains (19 strains with intermediate resistance and 8 strains with high resistance. Penicillin-resistance was higher in 2002–2004 than in 2005–2007 (39.5% vs 18.2%, p = 0.017. Of 27 penicillin-resistant strains, 10 (37% were resistant to erythromycin, 8 (29.6% to cefotaxime, 2 (7.4% to levofloxacin, and 4 (14.8% were identified as multidrug resistant. Case-fatality rate was higher among those patients who had an infection caused by any penicillin susceptible strain (16.9% than in those with infections due to penicillin-resistant strains. Conclusion Resistance to penicillin among Streptococcus pneumoniae remains high, but such resistance does not result in increased mortality in patients with pneumococcal pneumonia.

    Corticosteroids are frequently prescribed anti-inflammatory medications. Inhaled corticosteroids (ICS) are indicated for Chronic Obstructive Pulmonary Disease (COPD) and asthma. ICS are associated with a decrease in exacerbations and improved quality of life in COPD, however multiple studies have linked the chronic use of ICSs with an increased risk of developing pneumonia, though the effect on mortality is unclear. We review the association of ICS with the risk of pneumonia and the implications on clinical outcomes.

    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.

    Streptococcus pneumoniae is the leading cause of bacterial pneumonia, meningitis and sepsis in children worldwide. Despite available evidence on pneumococcal conjugate vaccine (PCV) impact on pneumonia hospitalizations in children, studies demonstrating PCV impact in morbidity and mortality in middle-income countries are still scarce. Given the disease burden, PCV7 was introduced in Peru in 2009, and then switched to PCV10 in late 2011. National public healthcare system provides care for 60% of the population, and national hospitalization, outpatient and mortality data are available. We thus aimed to assess the effects of routine PCV vaccination on pneumonia hospitalization and mortality, and acute otitis media (AOM) and all cause pneumonia outpatient visits in children under one year of age in Peru. We conducted a segmented time-series analysis using outcome-specific regression models. Study period was from January 2006 to December 2012. Data sources included the National information systems for hospitalization, mortality, outpatient visits, and RENACE, the national database of aggregated weekly notifications of pneumonia and other acute respiratory diseases (both hospitalized and non-hospitalized). Study outcomes included community acquired pneumonia outpatient visits, hospitalizations and deaths (ICD10 codes J12-J18); and AOM outpatient visits (H65-H67). Monthly age- and sex-specific admission, outpatient visit, and mortality rates per 100,000 children aged impact in morbidity and mortality in children aged <1year. Vaccine effectiveness was 26.2% (95% CI 16.9-34.4) for AOM visits, 35% (95% CI 8.6-53.8) for mortality due to pneumonia, and 20.6% (95% CI 10.6-29.5) for weekly cases of pneumonia hospitalization and outpatient visits notified to RENACE. We used secondary data sources which are usually developed for other non-epidemiologic purposes.

    Research in context: Pneumonia continues to be a high-burden illness around the globe. This paper shows that although research funding is increasing in the UK (between 1997 and 2013, it remains poorly funded compared to other important respiratory infectious diseases such as tuberculosis and influenza. Publications about pneumonia have been steadily increasing over time, indicating continuing academic and clinical interest in the topic. Though global mortality of pneumonia is declining, it should still be an area of high priority for funders, policymakers and researchers.

    Full Text Available In the absence of livestock contact, recurring lamb mortality in bighorn sheep (Ovis canadensis populations previously exposed to pneumonia indicates the likely presence of carriers of pneumonia-causing pathogens, and possibly inadequate maternally derived immunity. To investigate this problem we commingled naïve, pregnant ewes (n=3 with previously exposed rams (n=2. Post-commingling, all ewes and lambs born to them acquired pneumonia-causing pathogens (leukotoxin-producing Pasteurellaceae and Mycoplasma ovipneumoniae, with subsequent lamb mortality between 4-9 weeks of age. Infected ewes became carriers for two subsequent years and lambs born to them succumbed to pneumonia. In another experiment, we attempted to suppress the carriage of leukotoxin-producing Pasteurellaceae by administering an antibiotic to carrier ewes, and evaluated lamb survival. Lambs born to both treatment and control ewes (n=4 each acquired pneumonia and died. Antibody titers against leukotoxin-producing Pasteurellaceae in all eight ewes were ‘protective’ (>1:800 and no apparent respiratory disease; however their lambs were either born with comparatively low titers, or with high (but non-protective titers that declined rapidly within 2-8 weeks of age, rendering them susceptible to fatal disease. Thus, exposure to pneumonia-causing pathogens from carrier ewes, and inadequate titers of maternally derived protective antibodies, are likely to render bighorn lambs susceptible to fatal pneumonia.

    Streptococcus pneumoniae is the leading cause of bacterial pneumonia, meningitis and sepsis in children worldwide. Despite available evidence on pneumococcal conjugate vaccine (PCV) impact on pneumonia hospitalizations in children, studies demonstrating PCV impact in morbidity and mortality in middle-income countries are still scarce. Given the disease burden, PCV7 was introduced in Peru in 2009, and then switched to PCV10 in late 2011. National public healthcare system provides care for 60% of the population, and national hospitalization, outpatient and mortality data are available. We thus aimed to assess the effects of routine PCV vaccination on pneumonia hospitalization and mortality, and acute otitis media (AOM) and all cause pneumonia outpatient visits in children under one year of age in Peru. We conducted a segmented time-series analysis using outcome-specific regression models. Study period was from January 2006 to December 2012. Data sources included the National information systems for hospitalization, mortality, outpatient visits, and RENACE, the national database of aggregated weekly notifications of pneumonia and other acute respiratory diseases (both hospitalized and non-hospitalized). Study outcomes included community acquired pneumonia outpatient visits, hospitalizations and deaths (ICD10 codes J12-J18); and AOM outpatient visits (H65-H67). Monthly age- and sex-specific admission, outpatient visit, and mortality rates per 100,000 children aged Peru. PMID:27521230

    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.

    Ventilator-associated pneumonia (VAP) is a major healthcare-associated complication with considerable attributable morbidity, mortality and cost. Inherent design flaws in the standard high-volume low-pressure cuffed tracheal tubes form a major part of the pathogenic mechanism causing VAP.

    2010-11-01

    Full Text Available Abstract The epidemiology of MRSA pneumonia varies across countries. One of the most import risk factors for the development of nosocomial MRSA pneumonia is mechanical ventilation. Methicillin resistance in S. aureus ventilator associated pneumonia (VAP ranged between 37% in German, 54% in the US American and 78% in Asian and Latin American ICUs. In 2009, the incidence density of nosocomial VAP caused by MRSA was 0.28 per 1000 ventilation days in a network of 586 German ICUs. Incidences peaked in neurological and neurosurgical ICUs. Crude hospital mortality in studies performed after 2005 lay between 27% and 59% and attributable MRSA pneumonia mortality at 40%. Since 2005, US American and German data indicate decreasing trends for MRSA pneumonia. Measures to reduce MRSA pneumonia or to control the spread of MRSA include hand hygiene, standard and contact precautions, oral contamination with chlor hexidine, skin decontamination with antiseptics, screening, and (possibly patient isolation in a single room.

    Mortality from pneumonia is mediated, in part, through extrapulmonary causes. Epidermal growth factor (EGF) has broad cytoprotective effects, including potent restorative properties in the injured intestine. The purpose of this study was to determine the efficacy of EGF treatment following Pseudomonas aeruginosa pneumonia. FVB/N mice underwent intratracheal injection of either P. aeruginosa or saline and were then randomized to receive either systemic EGF or vehicle beginning immediately or 24 h after the onset of pneumonia. Systemic EGF decreased 7-day mortality from 65% to 10% when initiated immediately after the onset of pneumonia and to 27% when initiated 24 h after the onset of pneumonia. Even though injury in pneumonia is initiated in the lungs, the survival advantage conferred by EGF was not associated with improvements in pulmonary pathology. In contrast, EGF prevented intestinal injury by reversing pneumonia-induced increases in intestinal epithelial apoptosis and decreases in intestinal proliferation and villus length. Systemic cytokines and kidney and liver function were unaffected by EGF therapy, although EGF decreased pneumonia-induced splenocyte apoptosis. To determine whether the intestine was sufficient to account for extrapulmonary effects induced by EGF, a separate set of experiments was done using transgenic mice with enterocyte-specific overexpression of EGF (IFABP-EGF [intestinal fatty acid-binding protein linked to mouse EGF] mice), which were compared with wild-type mice subjected to pneumonia. IFABP-EGF mice had improved survival compared with wild-type mice following pneumonia (50% vs. 28%, respectively, P < 0.05) and were protected from pneumonia-induced intestinal injury. Thus, EGF may be a potential adjunctive therapy for pneumonia, mediated in part by its effects on the intestine. PMID:21701422

    Acute interstitial pneumonia (AIP) of feedlot cattle is a sporadically occurring respiratory condition that is often fatal. Affected cattle have a sudden onset of labored breathing. There is no confirmed effective treatment of feedlot AIP; however, administration of antibiotics effective against common bacterial respiratory pathogens and nonsteroidal anti-inflammatory drugs, especially aspirin, has been recommended. Protective strategies are not well defined, but efforts to limit dust exposure and heat stress; to ensure consistent formulation, mixing, and delivery of feed; and to identify and treat infectious respiratory disease in a timely manner may decrease rates of feedlot AIP.

    Wildlife mortality events usually occur unannounced and may find management agencies unaware. These events can become highly visible and politically charged affairs, depending upon the scale or species involved. The public, media, and (or) politicians may pressure managers, field investigators, and diagnosticians to quickly identify the cause or to comment on potential causes, the significance of the event, what is being done about it, and a resolution. It may be common during such events for speculation to rage, and for conflicting theories to be advanced to explain either the environmental conditions that led to the mortality or the actual cause of death.

    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. PMID:27343190

    Full Text Available BACKGROUND: Pneumococcal infections cause major morbidity and mortality in developing countries. We report the epidemiology of S. pneumoniae carriage in a developing region, the Gaza strip, and evaluate the theoretical coverage of carriage strains by pneumococcal conjugate vaccines (PCVs. METHODOLOGY: In 2009 we conducted a cross-sectional survey of S. pneumoniae carriage in healthy children and their parents, living throughout the Gaza strip. Data were collected and nasopharyngeal swabs were obtained. Antibiotic susceptibilities were determined by Vitek-2 and serotypes by the Quellung reaction. PRINCIPAL FINDINGS: S. pneumoniae carriage was detected in 189/379 (50% of children and 30/376 (8% of parents. Carriage prevalence was highest in children <6 months of age (63%. Significant predictors for child carriage were number of household members and DCC attendance. The proportion of pediatric and adults isolates with serotypes included in PCV7 were 32% and 20% respectively, and 46% and 33% in PCV13 respectively. The most prominent non-vaccine serotypes (NVT were 35B, 15B/C and 23B. Penicillin-nonsusceptible strains were carried by 70% of carriers, penicillin-resistant strains (PRSP by 13% and Multi-drug-resistant (MDR by 30%. Of all PRSP isolates 54% belonged to serotypes included in PCV7 and 71% in the PCV13. Similarly, 59% and 73% of MDR-SP isolates, would theoretically be covered by PCV7 and PCV13, respectively. CONCLUSIONS: This study demonstrates that, PCV13-included strains were carried by 46% and 33% of pediatric and adult subjects respectively. In the absence of definitive data regarding the virulence of the NVT strains, it is difficult to predict the effect of PCVs on IPD in this region.

    Full Text Available Imogen Johns Department of Clinical Sciences and Services, Royal Veterinary College, North Mymms, UK Abstract: Rhodococcus equi, a gram-positive facultative intracellular bacterial pathogen, is the most important cause of pneumonia in foals aged 3 weeks to 5 months. The disease occurs worldwide, resulting in significant morbidity and mortality on endemically affected farms. Foals appear to become infected early in life, but clinical signs are typically delayed until 1–3 months of age because of the insidious nature of the disease. Although pneumonia is the most common clinical manifestation, up to 74% of foals may concurrently have extrapulmonary disorders, including both extrapulmonary infections (abdominal abscessation, colitis, osteomyelitis and immune-mediated disorders (nonseptic synovitis, uveitis. Diagnosis is based on the combination of clinical signs and abnormalities on hematologic screening and thoracic imaging in an appropriately aged foal and is confirmed by bacteriologic culture of the organism. Management of R. equi infections, in particular on farms with endemic disease, combines appropriate treatment of affected foals with preventative measures targeted at preventing infection and identifying foals before the development of severe disease. The combination of rifampin and a macrolide antimicrobial is recommended for treatment, as the combination is synergistic, reaches high intracellular concentrations, and should minimize the development of antimicrobial resistance. The prognosis for survival for foals with R. equi pneumonia is good, especially in foals mildly or subclinically affected, as is the prognosis for future athletic performance. Screening for early identification before the development of clinical signs has been advocated on endemically affected farms, although the most appropriate method, the timing of screening, and the selection of foals requiring treatment have yet to be determined. Recent evidence suggests that

    Full Text Available Intravascular and intraalveolar coagulation can be found in severe pneumonia as a response to local and systemic inflammation process in severe pneumonia. Clinical consequences of this coagulation changes is an increase of plasma D-dimer levels as a marker of coagulation and fibrinolyis activation, the number of organ dysfunction even death. The aim of this study was to understand the validity of high plasma D-dimer levels as a predictor of mortality in 2 to 59-month-old pneumonia patients. This was a prospective observational analytic study which was held in Dr. Hasan Sadikin Hospital Bandung. The subjects of this study were 2 to 59 months old children who were diagnosed as pneumonia and visited Pediatric Emergency Departement during October–November 2009. Plasma D-dimer assay was performed at admission and observed until the patient died or discharged from the hospital. Forty-five children were included in this study, 15 (33% died during observation. Plasma D-dimer level showed significant correlations (p=0.04 with the mortality in 2 to 59-month-old pneumonia patients with median and range of 0.60 mg/L (0.1–5.10 mg/L. Plasma D-dimer cut-off point of >0.4 mg/L gave 73.3% sensitivity (CI 95%, 44.9–92.0%, and 70.0% specificity (CI 95%, 50.6–85.2% with 71.1% accuracy for predicting mortality in 2 to 59-month-old pneumonia patients. In conclusions, there were significant correlations between elevated plasma Ddimer levels and mortality in 2 to 59-month-old patients with pneumonia.

  7. Radiographic features of Mycoplasma pneumoniae pneumonia: differential diagnosis and performance timing

    International Nuclear Information System (INIS)

    The Japanese Respiratory Society guidelines propose a differential diagnosis for atypical pneumonia and bacterial pneumonia using a scoring system for the selection of appropriate antibiotic. In order to improve this scoring system, the guidelines are seeking new specific parameter. The purpose of this study was to clarify the pattern of abnormalities with Mycoplasma pneumoniae pneumonia on chest computed tomography (CT) and whether the radiographic findings could distinguish M. pneumoniae pneumonia from Streptococcus pneumoniae pneumonia. A retrospective review was performed of the CT findings of 64 cases and 68 cases where M. pneumoniae and S. pneumoniae, respectively, were the only pathogen identified by the panel of diagnostic tests used. Of the 64 patients with M. pneumoniae pneumonia, bronchial wall thickening was observed most frequently (81%), followed by centrilobular nodules (78%), ground-glass attenuation (78%), and consolidation (61%). Bronchial wall thickening and centrilobular nodules were observed more often in M. pneumoniae patients than in S. pneumoniae patients (p < 0.0001). The presence of bilateral bronchial wall thickening or centrilobular nodules was only seen in patients with M. pneumoniae pneumonia. Using the scoring system of the Japanese Respiratory Society guidelines and chest CT findings, 97% of M. pneumoniae patients were suspected to be M. pneumoniae pneumonia without serology. When comparing the CT findings between early stage and progressed stage in the same patients with severe pneumonia, the radiographic features of early stage M. pneumoniae pneumonia were not observed clearly in the progressed stage. The present results indicate that the diagnosis of M. pneumoniae pneumonia would appear to be reliable when found with a combination of bronchial wall thickening and centrilobular nodules in the CT findings. However, these CT findings are not observed in progressed severe M. pneumoniae pneumonia patients

The clinical database and electronic records were analyzed. Recently published literature was reviewed.Results There was more diabetes and hypertension in the infected group than in the non-infected group (86% vs 62% and 57% vs 39%, respectively). Eighty-six percent of recipients from the infected group had delayed graft function. Seven cases with aspergillus pneumonia were identified based on either fungal culture or radiology. Of the 7 cases, 4 died in a few days after diagnosis. Liposomal amphotericin B was used as a first-line therapy.Conclusions Incidences of fungal infection are increasing among renal transplant recipients. Early diagnosis and treatment are critical steps in curing aspergillosis.

    Full Text Available Abstract Background The World Health Organization's (WHO case definition for childhood pneumonia, composed of simple clinical signs of cough, difficult breathing and fast breathing, is widely used in resource poor settings to guide management of acute respiratory infections. The definition is also commonly used as an entry criteria or endpoint in different intervention and disease burden studies. Methods A group of paediatricians conducted a retrospective review of clinical and laboratory data including C-reactive protein concentration and chest radiograph findings among Filipino children hospitalised in the Bohol Regional Hospital who were enrolled in a pneumococcal vaccine efficacy study and had an episode of respiratory disease fulfilling the WHO case definition for clinical pneumonia. Our aim was to evaluate which disease entities the WHO definition actually captures and what is the probable aetiology of respiratory infections among these episodes diagnosed in this population. Results Among the 12,194 children enrolled to the vaccine study we recorded 1,195 disease episodes leading to hospitalisation which fulfilled the WHO criteria for pneumonia. In total, 34% of these episodes showed radiographic evidence of pneumonia and 11% were classified as definitive or probable bacterial pneumonia. Over 95% of episodes of WHO-defined severe pneumonia (with chest indrawing had an acute lower respiratory infection as final diagnosis whereas 34% of those with non-severe clinical pneumonia had gastroenteritis or other non-respiratory infection as main cause of hospitalisation. Conclusion The WHO definition for severe pneumonia shows high specificity for acute lower respiratory infection and provides a tool to compare the total burden of lower respiratory infections in different settings.

This study was conducted to determine when dermatology patients treated with immunosuppressive medications should be offered P. jiroveci pneumonia prophylaxis. We searched the literature from January 1, 1993, to December 31, 2013, using terms relating to P. jiroveci pneumonia and dermatologic diagnoses to analyze the clinical characteristics of previously affected patients. Guidelines for P. jiroveci pneumonia prophylaxis from other medical fields were also analyzed. Of 17 dermatology patients reported to have contracted P. jiroveci pneumonia, eight (47.1%) died of the pneumonia. Risk factors included lack of prophylaxis, systemic corticosteroid therapy, lymphopenia, hypoalbuminemia, low serum CD4 counts, comorbid pulmonary or renal disease, malignancy, and prior organ transplantation. The present conclusions are limited by heterogeneity among the selected studies and limitations in their identification and selection. However, P. jiroveci pneumonia in dermatology patients is associated with a high mortality rate. Based on our analysis, we propose that prophylaxis be considered in dermatology patients in whom treatment with systemic corticosteroids at doses exceeding 20 mg/day or treatment with corticosteroid-sparing immunosuppressive agents is anticipated for at least 4 weeks, and in patients with additional risk factors for P. jiroveci pneumonia.

    Lipoid pneumonia, first described by Laughlen 1925 may be classified as endogenous or exogenous. The endogenous form is seen when fat is deposited into the lung tissue. It is usually associated with proximal obstructive lesions, necrotic tissue after radio- or chemotherapy, with lipid storage disease or hyperlipidemia . Exogenous lipoid pneumonia results from inhaling or aspirating animal, vegetable or mineral oil. There are usually some underlying neurological defects or esophageal abnormalities. Patients may present with cough, sputum, hemoptysis and chest pain or may be asymptomatic. There is no classic chest film appearance: it may appear as diffuse airspace infiltration or localized consolidation simulating tumour. Computed tomography is diagnostically helpful and shows hypodense areas measuring from -100 to - 30 Hounsfield units. Bronchoscopic biopsies are mandatory for histological confirmation of the diagnosis. Treatment of exogenous lipoid pneumonia has always been conservative by discontinuing the use of oil, correction of underlying defects that may favor aspiration and treatment of intercurrent pneumonia. Other measures, for example corticosteroid therapy, are of uncertain benefit. Complications of lipoid pneumonia that worsen prognosis are recurrent bacterial pneumonias including nontuberculous mycobacteria or aspergillus, or lung cancer that has developed in areas of pre-existing exogenous lipoid pneumonia.

    Full Text Available Rajib K Bhattacharya, Jonathan D Mahnken, Sally K RiglerUniversity of Kansas School of Medicine, Kansas City, KS, USABackground: Community-acquired pneumonia (CAP is a common cause of morbidity and mortality in older adults. Although diabetes mellitus is a risk factor for pneumonia, the clinical impact of blood glucose level at the time of admission is not clear. Our goal was to examine the association between admission hyperglycemia and subsequent mortality, length of stay, and readmission outcomes in older adults with CAP.Methods: A retrospective observational study was conducted using hospital data for community-acquired pneumonia admissions in 857 persons from January 1, 2008 to December 31, 2010. We examined the effects of admission glucose level on mortality, length of stay, and 30 day readmission, adjusted for demographic factors and comorbidity.Results: The mean age of the sample was 64 years, and 51% of the subjects were female. Inpatient mortality occurred in 4.6% and the median length of stay was 5 days (interquartile range 3–9 days. Readmission within 30 days occurred in 17%. We found little impact of first glucose measures on in-hospital mortality (P = 0.94, length of stay (P = 0.95, and 30-day readmission (P = 0.56. Subjects 65 years and older trended towards higher in-hospital mortality. Older age, cancer, heart failure, and cirrhosis were associated with adverse outcomes.Conclusion: Glucose level upon admission for community-acquired pneumonia was not associated with adverse outcomes within 30 days in older adults.Keywords: community-acquired pneumonia, hyperglycemia, readmission rates, hospital mortality

    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.

    after vaccination, 133 were secondary to influenza. 9. The death rate for 155 cases of pneumonia (all types) that developed among vaccinated men 1 week or more after vaccination was only 12.2 per cent, whereas the death rate for 327 cases of all types that occurred among unvaccinated troops was 22.3 per cent. The death rate for primary pneumonia among vaccinated troops was 11.9 per cent. Among unvaccinated, it was 31.8 per cent, almost three times as great. On the other hand, the mortality rate in pneumonia secondary to influenza is about the same for the vaccinated and unvaccinated groups. 10. In conclusion, it must be admitted that the results of pneurnococcus vaccination at Camp Wheeler have not been so striking as those obtained at Camp Upton in 1918, largely on account of the influenza epidemic; but, although influenza obscured to some extent the effect of pneumococcus vaccination at Camp Wheeler, the results are sufficiently encouraging to justify its further application in civil as well as in military life.

  1. Osteopathic manipulative treatment as a useful adjunctive tool for pneumonia.

    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

    Objective On 11 March 2011, the Great East Japan Earthquake struck off Japan. Although some studies showed that the earthquake increased the risk of pneumonia death, no study reported whether and how much a tsunami increased the risk. We examined the risk for pneumonia death after the earthquake/tsunami. Design This is an ecological study. Setting Data on population and pneumonia deaths obtained from the Vital Statistics 2010 and 2012, National Census 2010 and Basic Resident Register 2010 and 2012 in Japan. Participants About 5.7 million participants residing in Miyagi, Iwate and Fukushima Prefectures during 1 year after the disaster were targeted. All municipalities (n=131) were categorised into inland (n=93), that is, the earthquake-impacted area, and coastal types (n=38), that is, the earthquake-impacted and tsunami-impacted area. Outcome measures The number of pneumonia deaths per week was totalled from 12 March 2010 to 9 March 2012. The number of observed pneumonia deaths (O) and the sum of the sex and age classes in the observed population multiplied by the sex and age classes of expected pneumonia mortality (E) were calculated. Expected pneumonia mortality was the pneumonia mortality during the year before. Standardised mortality ratios (SMRs) were calculated for pneumonia deaths (O/E), adjusting for sex and age using the indirect method. SMRs were then calculated by coastal and inland municipalities. Results 6603 participants died of pneumonia during 1 year after the earthquake. SMRs increased significantly during the 1st–12th weeks. In the 2nd week, SMRs in coastal and inland municipalities were 2.49 (95% CI 2.02 to 7.64) and 1.48 (95% CI 1.24 to 2.61), respectively. SMRs of coastal municipalities were higher than those of inland municipalities. Conclusions An earthquake increased the risk of pneumonia death and tsunamis additionally increased the risk.

    Community-acquired pneumonia remains a most widespread acute infectious disease of socio-economic significance all over the world. Up to 30% of the patients present with anemia responsible for the unfavourable prognosis and elevated mortality. Not infrequently, anemia is not diagnosed during the hospital stay und therefore remains uncorrected. Severe anemia results in enhanced hypercapnia and slowed maturation of red blood cells in the bone marrow which facilitates the development of ischemic syndrome. Hepcidin, a mediator of inflammation and iron-regulatory hormone, plays an important role in the clinical course of community-acquired pneumonia. Hepsidin production increases during inflammation; it suppresses erythtropoiesis and depletes the iron depot leading to so-called anemia of inflammation. Hypoxia and anemia activate erythtropoiesis, and the released erythropoietin inhibits hepsidin production. During pneumonia resolution, hepsidin promotes recovery from anemia by activating iron absorption. The curreni literature contains few data on the use of hepcidin as a diagnostic marker of anemia. The necessity oftreating anemia in patients with pneumonia under hospital conditions is a matter of discussion. Direct involvement of hepcidin in iron metabolism creates a prerequisite for the treatment of anemia. Medicamental suppression of its activity by stimulating erythtropoiesis can facilitate normalization of iron metabolism and restoration of hemoglobin level.

    Full Text Available OBJECTIVE Mortality rate of children is one of the important indicator of health status of country. India is one of the major contributor of under 5 mortality of the world. The present study was aimed at finding the causes of mortality among children admitted in paediatric ward of Assam Medical College Hospital during last two years and provides epidemiological information related to mortality. MATERIALS AND METHODS A retrospective cross-sectional descriptive study over 2 years’ period from 1st July 2013 to 31st June 2015 using data retrieved from the Hospital’s Admission and Death Record Register. Data collected was entered into a spreadsheet using SPSS software package version 16.0. RESULTS A total of 10970 children comprising of 4873 (44.4% males and 6097 (55.5 % of females were admitted to the Paediatric Department during this 24 months’ period. A total number of children died during this period was 814 comprising of 474 (58.2% males and 334 (41% females. Overall mortality among males and females were 9.72% and 5.47% respectively. An overall mortality of 7.42% was noted in cases admitted to the Paediatric ward. Out of total 814 paediatric deaths, 460 (57.9% were infant and more than 1/3rd (35.8% of infants died in new-born period; 186 (23.4% died in age group 1-5 years and 148 (18.1% died in age group >5 years. Majority of neonatal mortality was due to birth asphyxia (33.1% followed by septicaemia (31.4% and prematurity, LBW (18.5%. The common cause of post neonatal death was septicaemia (24% and respiratory tract infection (24% followed by meningitis (22.4%. Septicaemia (17.8% was the leading cause of death among infant. Acute encephalitis syndrome is the most common cause of death in 1-5 yrs. (24.1% and >5 yrs. (25% age group. CONCLUSION The pattern of childhood mortality has been documented in the present study. The results from this study confirm that high neonatal deaths were mainly due to birth asphyxia, while after neonatal

    Postinfluenza pneumococcal pneumonia is an important cause of global morbidity and mortality. What causes this increased susceptibility is not well elucidated. IL-35 is a newly described cytokine in infectious tolerance. A murine model was established to study postinfluenza pneumococcal pneumonia and evaluate the role of IL-35 in host defense against postinfluenza pneumococcal pneumonia. Pulmonary IL-35 was rapidly up-regulated during murine influenza infection, which was partially mediated by type I IFN-α/β receptor signaling pathway. Secondary pneumococcal infection led to a synergistic IL-35 response in influenza-infected mice. Clinical analysis showed that IL-35 levels were significantly elevated in the patients with influenza infection compared with healthy individuals and influenza infection could induce IL-35 production from human peripheral blood mononuclear cells. These data suggest that IL-35 contributes to the increased susceptibility to secondary pneumococcal pneumonia at least in part by inhibiting the early immune response.

    Pneumonia in the elderly often occurs repeatedly, and the mortality rate from pneumonia continues to remain high today despite the usual use of antibacterial chemotherapy. Therefore, we conducted immunotherapy using a polyvalent bacterial vaccine (broncasma Berna). We treated 54 elderly patients with Broncasma Berna, containing chief bacterial pathogens responsible for pneumonia in the elderly. Clinical results obtained during 2 years were compared with those of 18 subjects not treated with Broncasma Berna. The survival rate was 64.8% for the group treated with Broncasma Berna and 50% for the group not treated. The frequency of contraction of pneumonia decreased significantly in the group treated. Clinical efficacy was obtained in 63% of the group treated to prevent pneumonia. The death rate from pneumonia was 17.6% for the group treated and 44.4% for the group not treated. Immunologically, reinforcement in humoral and cellular immunities was indicated by immunoglobulin values, positive tuberculin skin tests, and an increase in lymphocyte stimulation index values for Broncasma Berna. Significant pathogens in sputum disappeared or decreased in 6 (54.6%) out of 11 patients. Side effects such as pain or redness at the site of injection were observed in 6 patients. From the above results, it may be concluded that Broncasma Berna can be considered to be effective as a long-term immunoprophylactic agent in the prevention of pneumonia in the elderly.

    Pneumonia is a leading cause of mortality and morbidity worldwide with radiographically confirmed pneumonia a key disease burden indicator. This is usually determined by a radiology panel which is assumed to be the best available standard; however, this assumption may introduce bias into pneumonia incidence estimates. To improve estimates of radiographic pneumonia incidence, we applied Bayesian latent class modelling (BLCM) to a large database of hospitalized patients with acute lower respiratory tract illness in Sa Kaeo and Nakhon Phanom provinces, Thailand from 2005 to 2010 with chest radiographs read by both a radiology panel and a clinician. We compared these estimates to those from conventional analysis. For children aged <5 years, estimated radiographically confirmed pneumonia incidence by BLCM was 2394/100 000 person-years (95% credible interval 2185-2574) vs. 1736/100 000 person-years (95% confidence interval 1706-1766) from conventional analysis. For persons aged ⩾5 years, estimated radiographically confirmed pneumonia incidence was similar between BLCM and conventional analysis (235 vs. 215/100 000 person-years). BLCM suggests the incidence of radiographically confirmed pneumonia in young children is substantially larger than estimated from the conventional approach using radiology panels as the reference standard.

    Bacteremic pneumonia is usually associated with greater mortality. However, risk factors associated with hospital mortality in bacteremic pneumonia are inadequately described.The study was a retrospective cohort study, conducted in Barnes-Jewish Hospital (2008-2015). For purposes of this investigation, antibiotic susceptibility was determined according to ceftriaxone susceptibility, as ceftriaxone represents the antimicrobial agent most frequently recommended for hospitalized patients with community-acquired pneumonia as opposed to nosocomial pneumonia. Two multivariable analyses were planned: the first model included resistance to ceftriaxone as a variable, whereas the second model included the various antibiotic-resistant species (methicillin-resistant Staphylococcus aureus, Pseudomonas aeruginosa, and Enterobacteriaceae).In all, 1031 consecutive patients with bacteremic pneumonia (mortality 37.1%) were included. The most common pathogens associated with infection were S aureus (34.1%; methicillin resistance 54.0%), Enterobacteriaceae (28.0%), P aeruginosa (10.6%), anaerobic bacteria (7.3%), and Streptococcus pneumoniae (5.6%). Compared with ceftriaxone-susceptible pathogens (46.8%), ceftriaxone-resistant pathogens (53.2%) were significantly more likely to receive inappropriate initial antibiotic treatment (IIAT) (27.9% vs 7.1%; P mechanical ventilation, immune suppression, prior hospitalization, prior antibiotic administration, septic shock, comorbid conditions, and severity of illness. In the second multivariable analysis that included the antibiotic-resistant species, IIAT was still associated with excess mortality, and P aeruginosa infection was identified as an independent predictor of mortality (OR 1.6, 95% CI 1.1-2.2, P = 0.047), whereas infection with ceftriaxone-resistant Enterobacteriaceae (OR 0.6, 95% CI 0.4-1.0, P = 0.050) was associated with lower mortality.More than one-third of our patients hospitalized with bacteremic pneumonia died

    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.

When present in infancy or early childhood, various nevoid and hereditary disorders are to be differentiated. In many cases, familial aggregation of the disease is seen and other autoimmune disorders may be associated. Segmental presentation is more common, and limited body surface area involvement is usual in this age group. Children with vitiligo often suffer from anxiety and depression because of their unusual appearance. Management of vitiligo in children is difficult as therapeutic options are restricted when compared to that in adult patients. Selection of treatment should be careful in these patients with the aim to achieve best results with minimal side effects as well as relieving patients′ and parents′ anxiety.

    Psoriasis is a common dermatosis in children with about one third of all patients having onset of disease in the first or second decade of life. A chronic disfiguring skin disease, such as psoriasis, in childhood is likely to have profound emotional and psychological effects, and hence requires special attention. Psoriasis in children has been reported to differ from that among adults being more frequently pruritic; plaque lesions are relatively thinner, softer, and less scaly; face and flexu...

    Full Text Available OBJECTIVE: There was an increased number of cases of meningoencephalitis caused by Streptococcus pneumoniae, after the successful vaccination campaigns against Neisseria meningitidis and Haemophilus influenzae. This paper aims at describing the clinical characteristics, the laboratory findings, the complications, and the therapeutic management of these patients, who have been suffering from this disease since 1993 to 2006. METHOD: Twelve children with Streptococcus pneumoniae meningoencephalitis admitted to the pediatric hospital of San Miguel del Padron, City of Havana in this period were assessed. RESULTS: Children under one year are the most frequently affected. Septic shock and brain edema were the most severe complications. Three patients died, implying that this disease has a serious course. Early treatment of brain edema is very important to reduce mortality. The elective drugs for treatment of these cases of Streptococcus pneumoniae meningoencephalitis were vancomycin combined with cephalosporin, cefotaxime or ceftriaxone type. CONCLUSION: Patients with Streptococcus pneumoniae meningoencephalitis show clinical characteristics, complications, and sequels that are different to other bacterial meningoencephalitis, meaning that they could be helpful for physicians considering the differential diagnosis of meningoencephalitis.OBJETIVO: Existe un incremento de la meningoencefalitis producida por Streptococcus pneumoniae, después de las campañas exitosas de vacunación contra Neisseria meningitidis y Haemophilus influenzae.

    China, as a whole, is about to meet the Millennium Development Goals for reducing the maternal mortality ratio (MMR) and infant mortality rate (IMR), but the disparities between rural area and urban area still exists. This study estimated the potential effectiveness of expanding coverage with high impact interventions using the Lives Saved Tool (LiST). It was found that gestational hypertension, antepartum and postpartum hemorrhage, preterm birth, neonatal asphyxia, and neonatal childhood pneumonia and diarrhea are still the major killers of mothers and children in rural area in China. It was estimated that 30% of deaths among 0-59 month old children and 25% of maternal deaths in 2008 could be prevented in 2015 if primary health care intervention coverage expanded to a feasible level. The LiST death cause framework, compared to data from the Maternal and Child Mortality Surveillance System, represents 60%-80% of neonatal deaths, 40%-50% of deaths in 1-59 month old children and 40%-60% of maternal deaths in rural areas of western China.

    Objective To describe the clinical features of reported cases of community-acquired pneumonia (CAP) due to methicillin-resistant Staphylococcus aureus (MRSA), and to evaluate the risk factors related to outcome. Methods A systematic search of databases from January 1995 to December 2009 was performed. Baseline characteristics of survivors and non-survivors in the hospital were compared with the χ2 test for categorical variables. Variables with P<0.2 were entered in Logistic regression. Survival analysis was estimated by the Kaplan-Meier method according to use of antimicrobials inhibiting toxin production. Results Fifty-two articles were identified reporting data on 74 patients, with 41.1% of total mortality, short duration of symptom onset to death [(6.1±11.0) days], and prolonged hospital admissions [(28.6±29.1) days]. Logistic regression analysis showed that influenza like symptoms (P=0.04), hemoptysis (P<0.01), leucopenia (P<0.01) were the risk factors associated with death, and using clindamycin or linezolid which could inhibit the Panton-Valentine leukocidin (PLV, P<0.01) was the factor associated with survival. Kaplan-Meier analysis indicated that the antibiotic therapies inhibiting toxin production were associated with improved outcome in these cases (χ2=21.59, P<0.01). Conclusion CAP due to MRSA is a severe disease with significant lethality. Empiric therapy of severe CAP with flu-like symptoms, hemoptysis and leucopenia should include coverage for MRSA. Targeted treatment with antimicrobials inhibiting toxin production appear to be more appropriate selection.%目的 揭示社区获得性耐甲氧西林金黄色葡萄球菌(CA-MRSA)肺炎临床特征及死亡相关危险因素.方法 系统检索1995年1月至2009年12月发表的中英文文献,对比分析CA-MRSA肺炎生存和死亡者的临床特征,对相关参数进行Logistic回归分析以探讨与死亡的关系.按照是否应用抑制杀白细胞素(PVL)治疗措施分层,对患

    highest immune response was obtained 14 days post 1st dose of immunization with extracted CPSs of the three Klebsiella pneumoniae subspecies. When mice were immunized with CPSs of Klebsiella pneumoniae subspecies, they were protected against virulent challenge with homologous or heterologous strains, as a result the mortality rates were reduced from 80, 75 and 65 to 5 to 15% of Klebsiella pneumoniae subsp. pneumoniae, Klebsiella pneumoniae subsp. ozaenae and Klebsiella pneumoniae subsp. rhinoscleromatis, respectively. Determination of the reisolation rates of Klebsiella pneumoniae subspecies from lung, liver and spleen were done on both immunized mice and challenged and on control mice. Histopathological studies have been done on both dead infected non-immunized and immunized mice. Lungs were the main organs that showed macroscopic and microscopic pathological changes. Finally, ELISA has been used for detection of CPSs of Klebsiella pneumoniae subspecies antibodies in sera of examined animals. The sensitivity of ELISA using CPSs extracted from Klebsiella pneumoniae subsp. pneumoniae, Klebsiella pneumoniae subsp. ozaenae and Klebsiella pneumoniae subsp. rhinoscleromatis was 87.7, 89.0 and 83.6%, respectively. The specificity of this ELISA was 93.4, 92.9 and 93.1%, respectively. ELISA using CPSs antigens could therefore serve as a valuable aid in serodiagnosis of Klebsiella pneumonia.

    94 maternal deaths and 1546 fetal and neonatal deaths were registered among 28,706 births at the CHU Averroes in Casablanca between 1978-80. 45% of women who deliver at the clinic are very poor and only 10% are relatively well off. Obstetrical antecedents were noted in 27% of the fetal deaths. 70% of the maternal deaths occurred in women aged 20-34. 32 maternal deaths occurred among 16,232 women with 1-2 children, 30 among 6514 women with 3-5 children, and 32 among 5960 women with 6-14 children. 11,027 of the 28,706 were primaparas. Perinatal mortality was 4.46% among primaparas, 8.24% among grand multiparas, and 4.1% among secondiparas. In 58 of the 94 cases of maternal mortality the woman was hospitalized after attempting delivery at home or in a village clinic. Among women with 1 or 2 children, hemorrhage was the cause of death in 8 cases, infection in 7 cases, eclampsia in 3 cases, thromboembolism in 2 cases, uterine inversion in 2 cases, pulmonary tuberculosis in 1 case, embolism in 5 cases, and other causes 1 case each. Among women with 3-5 children hemorrhage was the cause of death in 10 cases, septicemia in 3 cases, uterine rupture in 3 cases, eclampsia in 3 cases, uterine inversion in 2 cases, viral hepatitis in 2 cases, emboli in 2 cases, and other reasons 1 case each. Among grand multiparas hemorrhage was the cause of death in 11 cases, uterine rupture in 12 cases, peritonitis in 2 cases, eclampsia in 2 cases, emboli in 2 cases, and other causes 1 case each. 19 of the maternal deaths were judged to have been avoidable with better management. Prematurity and birth weight of 1000-2500 g associated or not with other pathology were found in 714 of 1546 perinatal deaths. Of 390 cases of death in utero with retention and maceration, 68 were caused by reno-vascular syndromes, 76 by maternal infections, 33 by maternal syphilis, 26 by fetal malformation, 18 by maternal diabetes, 10 by Rh incompatability, and 159 by indeterminate causes.

    Full Text Available Abstract Background Most guidelines have been proposing, for more than 15 years, a β-lactam combined with either a quinolone or a macrolide as empirical, first-line therapy of severe community acquired pneumonia (CAP requiring ICU admission. Our goal was to evaluate the outcome of patients with severe CAP, focusing on the impact of new rather than old fluoroquinolones combined with β-lactam in the empirical antimicrobial treatments. Methods Retrospective study of consecutive patients admitted in a 16-bed general intensive care unit (ICU, between January 1996 and January 2009, for severe (Pneumonia Severity Index > or = 4 community-acquired pneumonia due to non penicillin-resistant Streptococcus pneumoniae and treated with a β-lactam combined with a fluoroquinolone. Results We included 70 patients of whom 38 received a β-lactam combined with ofloxacin or ciprofloxacin and 32 combined with levofloxacin. Twenty six patients (37.1% died in the ICU. Three independent factors associated with decreased survival in ICU were identified: septic shock on ICU admission (AOR = 10.6; 95% CI 2.87-39.3; p = 0.0004, age > 70 yrs. (AOR = 4.88; 95% CI 1.41-16.9; p = 0.01 and initial treatment with a β-lactam combined with ofloxacin or ciprofloxacin (AOR = 4.1; 95% CI 1.13-15.13; p = 0.03. Conclusion Our results suggest that, when combined to a β-lactam, levofloxacin is associated with lower mortality than ofloxacin or ciprofloxacin in severe pneumococcal community-acquired pneumonia.

    Although the severe acute respiratory illness (SARI) case definition is increasingly used for inpatient influenza surveillance, pneumonia is a more familiar term to clinicians and policymakers. We evaluated WHO case definitions for severe acute respiratory illness (SARI) and pneumonia (Integrated Management of Childhood Illnesses (IMCI) for children aged <5 years and Integrated Management of Adolescent and Adult Illnesses (IMAI) for patients aged ≥13 years) for detecting laboratory-confirmed influenza among hospitalized ARI patients. Sensitivities were 84% for SARI and 69% for IMCI pneumonia in children aged <5 years and 60% for SARI and 57% for IMAI pneumonia in patients aged ≥13 years. Clinical pneumonia case definitions may be a useful complement to SARI for inpatient influenza surveillance. PMID:27219455

The aim of our study was to analyse the risk of suicide among childhood cancer survivors compared with that ofthe general population of Slovenia. Patients and methods. This retrospective study included patients with childhood cancer registeredat the Cancer Registry of Slovenia between 1978-2008, with an observation period of 1978-2010. Childhood cancer patients and controlsubjects from the general population of Slovenia were matched by sex,year and age at the beginning of follow-up and time of follow-up inyears. Data on the general population of Slovenia were obtained fromthe Statistical Office of the Republic of Slovenia. Results. A total of 1647 patients were recorded in the Cancer Registry as having cancerduring childhood, with 3 patients committing suicide. All three weremale. Their age at diagnosis of cancer was 12, 13 and 2 years old; their age at suicide was 19, 32 and 28 years old. The mechanism of death was asphyxiation in all three deaths. The calculation of the expected number of suicides in the group of individuals with childhood cancer from the general Slovene population revealed the number of 3.16persons. Conclusion. The comparison of the observed and expectedprobability showed that there was no statistically significant difference in the suicide rate between childhood cancer survivors and the general population of Slovenia.

  1. Childhood psoriasis

    Directory of Open Access Journals (Sweden)

    Dogra Sunil

    2010-01-01

    Full Text Available Psoriasis is a common dermatosis in children with about one third of all patients having onset of disease in the first or second decade of life. A chronic disfiguring skin disease, such as psoriasis, in childhood is likely to have profound emotional and psychological effects, and hence requires special attention. Psoriasis in children has been reported to differ from that among adults being more frequently pruritic; plaque lesions are relatively thinner, softer, and less scaly; face and flexural involvement is common and guttate type is the characteristic presentation. Whether onset in childhood predicts a more severe form of psoriasis is a matter of controversy, it may cause significant morbidity particularly if it keeps relapsing. Most children have mild form of psoriasis which can be generally treated effectively with topical agents such as emollients, coal tar, corticosteroids, dithranol, calcipotriol etc. according to age and the sites affected. Narrow band UVB is the preferred form of phototherapy in children for moderate to severe disease or in patients not responding to topical therapy alone. Systemic therapies are reserved for more severe and extensive cases that cannot be controlled with topical treatment and/or phototherapy such as severe plaque type, unstable forms like erythrodermic and generalized pustular psoriasis and psoriatic arthritis. There are no controlled trials of systemic therapies in this age group, most experience being with retinoids and methotrexate with favorable results. Cyclosporine can be used as a short-term intermittent crisis management drug. There is an early promising experience with the use of biologics (etanercept and infliximab in childhood psoriasis. Systemic treatments as well as phototherapy have limited use in children due to cumulative dose effects of drugs, low acceptance, and risk of gonadal toxicity. More evidence-based data is needed about the effectiveness and long-term safety of topical

    Organising pneumonia is one of the responses of the lung to injury and can mimic bacterial pneumonia but importantly it does not respond to antibiotic therapy. We present the case of a 67-year-old male who was diagnosed with organising pneumonia secondary to dronedarone. Drug reactions are a common cause and early identification of the culprit is mandatory to prevent further morbidity and ensure a favourable outcome. On chest radiography there may be fleeting peripheral consolidation, while computed tomography can show a range of stereotyped patterns including perilobular consolidation. Bronchoscopic biopsy may not always be possible but response to steroids is often rapid following removal of the culprit drug. Dronedarone should be included in the list of possible drugs and the Pneumotox database remains a useful resource for the clinician when acute drug-related pneumotoxicity is suspected. PMID:26517101

  6. Imaging appearances of cholesterol pneumonia

    International Nuclear Information System (INIS)

    Objection: To analyze the imaging appearances of cholesterol pneumonia. Methods We retrospectively analyzed the X-ray and CT findings of 3 patients with cholesterol pneumonia confirmed pathologically and reviewed correlative literature. Results: Lesions similar to mass were found in X-ray and CT imaging of three cases. Two of them appeared cavity with fluid-level and one showed multiple ring enhancement after CT contrast. The course of disease was very. long and it had no respond to antibiotic therapy. Amounts of foam cells rich in cholesterol crystal were detected in pathological examination. Conclusions: Cholesterol pneumonia is a rare chronic pulmonary idiopathic disease, and the radiological findings can do some help to its diagnosis. (authors)

    Psoriasis is a common skin disease in infants, children, and adolescents. A review of the clinical, epidemiologic, genetic, and therapeutic aspects of childhood psoriasis is presented. Population studies indicate that the first signs of psoriatic lesions occur in the pediatric age group, birth to 18 years of age, and that both genetic and environmental factors interact to precipitate the development of psoriasis. Koebner reactions are the result of external or internal triggering factors, such as physical injury to the skin, low humidity, and certain drugs. The most frequently observed variant to psoriasis is the plaque type, followed by guttate psoriasis, and juvenile psoriatic arthritis. Pustular psoriasis and erythrodermic psoriasis are rare forms of the disease, but are seen in children from infancy to adolescence. The scalp is the most frequently affected site of involvement in pediatric psoriasis, followed by the appearance of lesions on the extensor surfaces of the extremities, trunk, and nails. Although not common in adult psoriasis, the face and ears are often involved. Topical medications such as corticosteroids, calcipotriol, coal tar preparations, anthralin formulations, and ultraviolet B are recommended in monotherapy or in combination therapy, whereas psoralen plus ultraviolet A, methotrexate, and retinoids should only be administered in crisis situations. The treatment objectives in childhood psoriasis are to preserve skin surfaces, to afford physical relief from the disease, and to employ treatments that do not endanger the health or future development of the child.

    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 A 67-year-old man suffering from esophageal cancer was admitted to our hospital complaining of dyspnea and hypoxemia. He had been treated with cisplatin, docetaxel, and fluorouracil combined with radiotherapy. 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.

    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.

    Pneumonia is the second leading reason for hospitalization of medicare beneficiaries. The mortality rate is high, especially in the elderly. In this study, we aimed to determine the risk factors associated with severe pneumonia in the elderly. Retrospective study was conducted and data of old patients with severe pneumonia were collected. They were divided into two groups: the experiment group (death group) and the control (living group). The general situation, underlying diseases, laboratory tests, types of etiology, imaging analysis and treatment situation of patients were analyzed and compared. Univariate analysis and logistic multivariate regression analysis were used to screen the related and independent risk factors for the diagnosis of severe pneumonia in the elderly. In univariate analysis, there were many factors had statistical significance including chronic kidney disease, electrolyte disturbance, low phosphorus and so on. Result of logistic multivariate regression analysis showed pro-BNP level and serum prealbumin were independent risk factors. In sputum culture, the relevance ratio of acinetobacter baumannii was the highest in gram negative bacteria followed by klebsiella pneumoniae. In gram positive bacteria, the relevance ratio of staphylococcus aureus was the highest. In conclusion, the analysis on risk factors for severe pneumonia has great clinical significance on improving the prognosis. PMID:26550157

    Pneumococcal pneumonia is a leading cause of mortality worldwide. The inflammatory response to bacteria is necessary to control infection, but it may also contribute to tissue damage. Phosphodiesterase-4 inhibitors, such as rolipram (ROL), effectively reduce inflammation. Here, we examined the impact of ROL in a pneumococcal pneumonia murine model. Mice were infected intranasally with 10(5)-10(6) CFU of Streptococcus pneumoniae, treated with ROL in a prophylactic or therapeutic schedule in combination, or not, with the antibiotic ceftriaxone. Inflammation and bacteria counts were assessed, and ex vivo phagocytosis assays were performed. ROL treatment during S. pneumoniae infection decreased neutrophil recruitment into lungs and airways and reduced lung injury. Prophylactic ROL treatment also decreased cytokine levels in the airways. Although modulation of inflammation by ROL ameliorated pneumonia, bacteria burden was not reduced. On the other hand, antibiotic therapy reduced bacteria without reducing neutrophil infiltration, cytokine level, or lung injury. Combined ROL and ceftriaxone treatment decreased lethality rates and was more efficient in reducing inflammation, by increasing proresolving protein annexin A1 (AnxA1) expression, and bacterial burden by enhancing phagocytosis. Lack of AnxA1 increased inflammation and lethality induced by pneumococcal infection. These data show that immunomodulatory effects of phosphodiesterase-4 inhibitors are useful during severe pneumococcal pneumonia and suggest their potential benefit as adjunctive therapy during infectious diseases.

  16. Independent radiographic prognostic factors in patients with hospital-treated community-acquired pneumonia

    International Nuclear Information System (INIS)

    Purpose: To evaluate the independent prognostic impact of the chest radiograph for mortality from community-acquired pneumonia requiring hospitalization. Methods: Chest radiographs of 67 patients with hospital-treated community-acquired pneumonia were analyzed with regard to the prognostic implications of radiographic patterns, extent and density of infiltrates, and its evolution during treatment. Results: Non-survivors had a significantly higher extent of infiltrates (p=0.008), density of infiltrates (p=0.05), and radiographic spread during follow-up within 48-72 hours (p=0.0001). In multivariate analysis, persistent or progressive infiltrates were associated with a 47fold increase, and persistent or progressive density of infiltrates with an 18fold increase in risk of mortality. The presence of both parameters could correctly predict 96% of survivors and 90% of non-survivors. Conclusions: The chest radiograph is an independent predictor of the severity of pneumonia. Both persistent or progressive infiltrates and persistent or progressive density of infiltrates are independently associated with mortality from community-acquired pneumonia. (orig.)

  17. Organizing pneumonia: the many morphological faces

    International Nuclear Information System (INIS)

    Organizing pneumonia is a non-specific response to various forms of lung injury and is the pathological hallmark of the distinct clinical entity termed cryptogenic organizing pneumonia. The typical imaging features of this syndrome have been widely documented and consist of patchy air-space consolidation, often subpleural, with or without ground-glass opacities. The purpose of this article is to highlight the less familiar imaging patterns of organizing pneumonia which include focal organizing pneumonia, a variety of nodular patterns, a bronchocentric distribution, band-like opacities, a perilobular pattern and a progressive fibrotic form of organizing pneumonia.

    2000-02-01

    We report a case of severe community-acquired pneumonia caused by Streptococcus pyogenes (Lancefield Group A streptoccocus) that was complicated by a streptococcal toxic shock syndrome. Although this micro-organism is an uncommon cause of community-acquired pneumonia, previously well individuals may be infected and the clinical course may be fulminant. A household contact was the likely point of infection. Invasive group A streptococcal disease continues to remain an important cause of morbidity and mortality in the community and therefore will continue to be encountered by intensive care physicians. Treatment of Group A streptococcal infection remains penicillin; however, clindamycin should be added in severe infection. PMID:10701045

    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.

    Lipoid pneumonia is a rare medical condition, and is usually classified into two groups, ie, exogenous or endogenous, depending on the source of lipids found in the lungs. Exogenous lipoid pneumonia may result from the aspiration of food and lipids. Although most cases are asymptomatic, common symptoms include cough, dyspnea, chest pain, pleural effusions, fever, and hemoptysis. Radiologically, lipoid pneumonia can manifest as consolidations, pulmonary nodules, or soft-tissue densities. These presentations involve a wide differential diagnosis, including lung cancer. Other rare causes of fatty pulmonary lesions include hamartomas, lipomas, and liposarcomas. The avoidance of further exposures and the use of corticosteroids, antibiotics, and lavage comprise the mainstays of treatment. The exclusion of mycobacterial infections is important during diagnosis, in view of their known association. Generally, acute presentations run a benign course, if promptly treated. Chronic cases are more persistent and difficult to treat. Although the radiologic and pathologic diagnosis is fairly reliable, more research is needed to clarify the optimal treatment and expected outcomes. We report on a 54-year-old man presenting with progressively worsening cough, hemoptysis, and dyspnea over a few weeks. The patient underwent multiple computed tomographies of the chest and bronchoscopies. All failed to diagnose lipoid pneumonia. The diagnosis was finally established using video-assisted thoracoscopic surgery. Most of the paraffinoma was resected during this surgery. He was treated with antibiotics and steroids, and discharged from the hospital in stable condition. PMID:21349583

    Full Text Available Lipoid pneumonia is a rare form of pneumonia caused by inhalation or aspiration of fat-containing substances like petroleum jelly, mineral oils, certain laxatives, etc. It usually presents as an insidious onset, chronic respiratory illness simulating interstitial lung diseases. Rarely, it may present as an acute respiratory illness, especially when the exposure to fatty substance(s is massive. Radiological findings are diverse and can mimic many other diseases including carcinoma, acute or chronic pneumonia, ARDS, or a localized granuloma. Pathologically it is a chronic foreign body reaction characterized by lipid-laden macrophages. Diagnosis of this disease is often missed as it is usually not considered in the differential diagnoses of community-acquired pneumonia; it requires a high degree of suspicion. In suspected cases, diagnosis may be confirmed by demonstrating the presence of lipid-laden macrophages in sputum, bronchoalveolar lavage fluid, or fine needle aspiration cytology/biopsy from the lung lesion. Treatment of this illness is poorly defined and constitutes supportive therapy, repeated bronchoalveolar lavage, and corticosteroids.

    This study describes the molecular characteristics and risk factors associated with carbapenem-resistant Klebsiella pneumoniae strains. Risk factors associated with KPC-producing K. pneumoniae strains were investigated in this case-control study from May 2011 to May 2013. Bacterial identification was performed by matrix-assisted laser desorption/ionization-time-of-flight mass spectrometry (MALDI-TOF MS). Antimicrobial susceptibility was determined by broth microdilution. Carbapenemase production was assessed by both modified Hodge test (MHT) and ertapenem hydrolysis using MALDI-TOF MS. The presence of β-lactamase-encoding genes was evaluated by PCR and DNA sequencing. Alterations in genes encoding K. pneumoniae outer membrane proteins were analysed by PCR and DNA sequencing as well as SDS-PAGE. Genetic relatedness among strains was determined by pulsed-field gel electrophoresis. This study included 94 patients. Longer hospitalisation, mechanical ventilation, catheters, and previous surgery were associated with KPC-producing K. pneumoniae. Sixty-eight strains showed resistance to carbapenems. Carbapenemase production was detected by MHT in 67 K. pneumoniae strains and by MALDI-TOF MS in 57. The presence of the blaKPC-2 gene was identified in 57 strains. The blaKPC-2 gene was not found in 11 carbapenem-resistant K. pneumoniae; instead, the blaCTX-M-1-like, blaCTX-M-2-like, blaCTX-M-8 like, blaCTX-M-14-like and blaSHV- like genes associated with OmpK35 and OmpK36 alterations were observed. Thirty-three KPC-producing K. pneumoniae strains were clonally related, and patients infected with these strains had a higher mortality rate (78.78 %). Our results show that KPC-producing K. pneumoniae was associated with several healthcare-related risk factors, including recent surgery.

    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

    There is a considerable amount of evidence that supports the possibility of an increased risk of pneumonia associated with prolonged use of inhaled corticosteroids (ICS) in patients with chronic obstructive pulmonary disease (COPD). However, as yet, no statistically significant increase in pneumonia-related 30-day mortality in patients on ICS has been demonstrated. The lack of objective pneumonia definitions and radiological confirmations have been a major source of bias, because of the similarities in clinical presentation between pneumonia and acute exacerbations of COPD. One of the newer fluticasone furoate studies overcomes these limitations and also provides an assessment of a range of doses, suggesting that the therapeutic window is quite narrow and that conventional dosing has probably been too high, although the absolute risk may be different compared to other drugs. Newer studies were not able to rule out budesonide as responsible for pneumonia, as previous evidence suggested, and there is still need for evidence from head-to-head comparisons in order to better assess possible intra-class differences. Although the exact mechanisms by which ICS increase the risk of pneumonia are not fully understood, the immunosuppressive effects of ICS on the respiratory epithelium and the disruption of the lung microbiome are most likely to be implicated. Given that COPD represents such a complex and heterogeneous disease, attempts are being made to identify clinical phenotypes with clear therapeutic implications, in order to optimize the pharmacological treatment of COPD and avoid the indiscriminate use of ICS. If deemed necessary, gradual withdrawal of ICS appears to be well tolerated. Vaccination against pneumococcus and influenza should be emphasized in patients with COPD receiving ICS. Physicians should keep in mind that signs and symptoms of pneumonia in COPD patients may be initially indistinguishable from those of an exacerbation, and that patients with COPD

    India has the highest number of global deaths of children under 5 years of age. In the year 2015, it was reported that there were 5.9 million deaths of children under 5 years of age globally, of which 1.2 million (20%) occurred in India alone. Currently, India has an under 5 mortality rate of 48 per 1000 live births. Community-acquired pneumonia contributes to about one sixth of this mortality. Fast breathing is the key symptom of community-acquired pneumonia. The World Health Organization recently categorized community-acquired pneumonia in children under 5 years of age into two, pneumonia, and severe pneumonia. Fast breathing with or without chest in-drawing is categorized as pneumonia and fast breathing with any of danger signs as severe pneumonia. Because effective vaccines against two of the common organisms causing community-acquired pneumonia, namely Streptococcus pneumoniae and Haemophilus influenzae type b, are available, there should be urgent and phased introduction into the Indian Universal Immunization Programme. Several preventable risk factors of community-acquired pneumonia such as lack of exclusive breast feeding for first 6 months of life, inappropriate complimentary feeding, iron deficiency anemia, malnutrition, and indoor air pollution should be adequately addressed. The community should be aware about the signs and symptoms of community-acquired pneumonia and its danger signs so that delay in qualified care seeking can be avoided. To achieve the sustainable development goal of ⩽25 under five deaths per 1000 live births by 2030, a multipronged approach is the need of the hour. PMID:27536353

    2014-01-01

    The severity and frequency of childhood obesity has increased significantly over the past three to four decades. The health effects of increased body mass index as a child may significantly impact obese youth as they age. However, many of the long-term outcomes of childhood obesity have yet to be studied. This article examines the currently available longitudinal data evaluating the effects of childhood obesity on adult outcomes. Consequences of obesity include an increased risk of developing the metabolic syndrome, cardiovascular disease, type 2 diabetes and its associated retinal and renal complications, nonalcoholic fatty liver disease, obstructive sleep apnea, polycystic ovarian syndrome, infertility, asthma, orthopedic complications, psychiatric disease, and increased rates of cancer, among others. These disorders can start as early as childhood, and such early onset increases the likelihood of early morbidity and mortality. Being obese as a child also increases the likelihood of being obese as an adult, and obesity in adulthood also leads to obesity-related complications. This review outlines the evidence for childhood obesity as a predictor of adult obesity and obesity-related disorders, thereby emphasizing the importance of early intervention to prevent the onset of obesity in childhood.

    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.

    The prevalence of childhood obesity is rising rapidly, as are the associated medical complications, including type 2 diabetes, hypertension, and coronary heart disease. This has significant medical and socioeconomic implications. The definition of obesity in adults is based on body mass index (BMI), which has been correlated with morbidity and mortality. Similarly, the definition of childhood obesity is currently based on BMI; however, there are currently no data to relate morbidity and mortality to BMI values in children. The known and potential causes of childhood obesity are many, but they can be categorized as genetic, endocrine, prenatal/early life, physical activity, diet, and socioeconomic. These factors influence the basic equation: energy input = energy output. Imbalances in this equation can result in obesity. Here we present a review of recent literature and highlight the etiologies, certain complications, and potential prevention and treatment strategies of childhood obesity.

    Full Text Available Abstract Background Pneumonia is one of the leading causes of morbidity and mortality in under fives. We carried out a comprehensive study to identify factors influencing both mortality and morbidity for children less than 5 years of age hospitalized with severe pneumonia. Methods 200 hospitalized children aged 2–60 months with World Health Organization (WHO defined severe pneumonia were enrolled in the study. The children were managed using a standard protocol. They were closely followed up for need for change in antibiotics, prolonged hospital stay, need for mechanical ventilation and mortality. Data on the factors influencing the outcome were collected. Results Of 200 children enrolled in the study, 113 (56.5% needed a change in antibiotics, 102 (51% stayed for more than 5 days in the hospital, 41 (20.5% needed mechanical ventilation and 21 (10.5% died. On multivariate analysis, lack of exclusive breastfeeding [RR (95%CI 2.63 (2.16–2.86], overcrowding [RR (95%CI 1.94 (1.35–2.38] and an abnormal chest x-ray [RR (95%CI 2.29 (1.22–3.44] were associated with the need for change of antibiotics. Lack of exclusive breastfeeding [RR (95%CI 2.56 (2.0–2.93], overcrowding [RR (95%CI 2.59 (1.78–3.23] and an abnormal chest x-ray [RR (95%CI 2.99 (1.65–4.38] were identified as determinants for prolonged hospital stay. Head nodding [RR (95%CI 8.34 (2.71–12.77], altered sensorium [RR (95%CI 5.44 (1.34–17.56], abnormal leukocyte counts [RR (95%CI 5.85(1.36–17.14] and pallor [RR (95%C 10.88 (2.95–20.40] were associated with mortality. Head nodding (RR (95% CI 4.73 (1.50–6.36] and cyanosis (RR (95%CI 5.06 (1.80–11.34] were the determining factors for mechanical ventilation. In radiographically confirmed pneumonia, the determining factors for change of antibiotics were: lack of exclusive breast feeding [RR (95% CI 2.05 (1.69–2.2] and low birth weight [RR (95% CI 1.59 (1.1–1.89].

    Full Text Available The continuous expansion of nosocomial infections around the globe has become a precarious situation. Key challenges include mounting dissemination of multiple resistances to antibiotics, the easy transmission and the growing mortality rates of hospital-acquired bacterial diseases. Thus, new ways to rapidly detect these infections are vital. Consequently, researchers around the globe pursue innovative approaches for point-of-care devices. In many cases the specific interaction of an antigen and a corresponding antibody is pivotal. However, the knowledge about suitable antigens is lacking. The aim of this study was to identify novel antigens as specific diagnostic markers. Additionally, these proteins might be aptly used for the generation of vaccines to improve current treatment options. Hence, a cDNA-based expression library was constructed and screened via microarrays to detect novel antigens of Klebsiella pneumoniae, a prominent agent of nosocomial infections well-known for its extensive antibiotics resistance, especially by extended-spectrum beta-lactamases (ESBL. After screening 1536 clones, 14 previously unknown immunogenic proteins were identified. Subsequently, each protein was expressed in full-length and its immunodominant character examined by ELISA and microarray analyses. Consequently, six proteins were selected for epitope mapping and three thereof possessed linear epitopes. After specificity analysis, homology survey and 3d structural modelling, one epitope sequence GAVVALSTTFA of KPN_00363, an ion channel protein, was identified harboring specificity for K. pneumoniae. The remaining epitopes showed ambiguous results regarding the specificity for K. pneumoniae. The approach adopted herein has been successfully utilized to discover novel antigens of Campylobacter jejuni and Salmonella enterica antigens before. Now, we have transferred this knowledge to the key nosocomial agent, K. pneumoniae. By identifying several novel antigens

  18. CT scan findings of fungal pneumonia

    International Nuclear Information System (INIS)

    The importance of fungal infection of the lung in immunocompromised patients has increased substantially during the last decades. Numerically the most patients are those with neutropenia, e.g. patients with malignancies or solid organ and stem cell transplantation, chemotherapy, corticosteroid use and HIV infection. Although fungal infections can occur in immunocompetent patients, their frequency in this population is rare. The clinical symptoms such as fever accompanied with non-productive cough are unspecific. In some patients progression to hypoxemia and dyspnea may occur rapidly. In spite of improved antifungal therapy morbidity and mortality of these infections are still high. Therefore an early and non-invasive diagnosis is very important. That is why CT and even better High-Resolution-CT (HR-CT) is a very important modality in examining immunocompromised patients with a probability of fungal infection. CT is everywhere available and, as a non-invasive method, able to give the relevant diagnose efficiently. This paper should give an overview about the radiologic findings and possible differential diagnosis of diverse pulmonary fungal infections in CT. Pneumonias caused by Aspergillus, Cryptococcus, Candida, Histoplasma, Mucor and Geotrichum capitatum are illustrated. (orig.)

  19. Influenza excess mortality from 1950-2000 in tropical Singapore.

    Directory of Open Access Journals (Sweden)

    Vernon J Lee

    Full Text Available INTRODUCTION: Tropical regions have been shown to exhibit different influenza seasonal patterns compared to their temperate counterparts. However, there is little information about the burden of annual tropical influenza epidemics across time, and the relationship between tropical influenza epidemics compared with other regions. METHODS: Data on monthly national mortality and population was obtained from 1947 to 2003 in Singapore. To determine excess mortality for each month, we used a moving average analysis for each month from 1950 to 2000. From 1972, influenza viral surveillance data was available. Before 1972, information was obtained from serial annual government reports, peer-reviewed journal articles and press articles. RESULTS: The influenza pandemics of 1957 and 1968 resulted in substantial mortality. In addition, there were 20 other time points with significant excess mortality. Of the 12 periods with significant excess mortality post-1972, only one point (1988 did not correspond to a recorded influenza activity. For the 8 periods with significant excess mortality periods before 1972 excluding the pandemic years, 2 years (1951 and 1953 had newspaper reports of increased pneumonia deaths. Excess mortality could be observed in almost all periods with recorded influenza outbreaks but did not always exceed the 95% confidence limits of the baseline mortality rate. CONCLUSION: Influenza epidemics were the likely cause of most excess mortality periods in post-war tropical Singapore, although not every epidemic resulted in high mortality. It is therefore important to have good influenza surveillance systems in place to detect influenza activity.

    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.

    Full Text Available Listeria Monositogenes is a facultative anaerob gram(+ agents that presents in soil, water, plants and in many mammals intestinal system.  Listeria Monositogenes is one of the most common factors of early neonatal sepsis and neonatal pneumonia during the perinatal period. Maternal obstetric complications are frequently seen in patients. Patients are often premature and have low birth weight. Responsible microorganisms frequently originate from maternal. The disease involes multisystems and the prognosis is usually fulminant.  In the congenital pneumonia, respiratory distress syndrome is prominent. Symptomatic spontaneous pneumothorax  brings about serious morbidity and mortality in newborns. The cause and risk factors of symptomatic pneumothorax in term newborns are not completely understood. The risk factors were reported as prematurity, male sex, high birth weight and birth the use of vacuum. We aimed to present a case with neonatal pneumonia associated with symptomatic spontaneous pneumothorax due to Listeria Monositogenes.

    Medulloblastoma accounts for 15-20% of childhood nervous system tumours. The risk of dying was reduced by 30% in the last twenty years. Patients are divided in risk strata according to post-surgical disease, dissemination, histology and some molecular features such as WNT subgroup and MYC status. Sixty to 70% of patients older than 3 years are assigned to the average-risk group. High-risk patients include those with disseminated and/or residual disease, large cell and/or anaplastic histotypes, MYC genes amplification. Current and currently planned clinical trials will: (1) evaluate the feasibility of reducing both the dose of craniospinal irradiation and the volume of the posterior fossa radiotherapy (RT) for those patients at low biologic risk, commonly identified as those having a medulloblastoma of the WNT subgroup; (2) determine whether intensification of chemotherapy (CT) or irradiation can improve outcome in patients with high-risk disease; (3) find target therapies allowing tailored therapies especially for relapsing patients and those with higher biological risk.

    Genotyping at the internal transcribed spacer (ITS) regions of the nuclear rRNA operon was performed on isolates of P. carinii sp. f. hominis from three clusters of P. carinii pneumonia among eight patients with haematological malignancies and six with HIV infection. Nine different ITS sequence...... types of P. carinii sp. f. hominis were identified in the samples from the patients with haematological malignancies, suggesting that this cluster of cases of P. carinii pneumonia was unlikely to have resulted from nosocomial transmission. A common ITS sequence type was observed in two of the patients...... with haematological malignancies who shared a hospital room, and also in two of the patients with HIV infection who had prolonged close contact on the ward. In contrast, different ITS sequence types were detected in samples from an HIV-infected homosexual couple who shared the same household. These data suggest...

    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. PMID:26122810

  6. Miliary pattern in neonatal pneumonia

    International Nuclear Information System (INIS)

    We have seen 10 newborn babies who developed respiratory distress and whose chest radiographs showed a miliary nodular pattern of disease. Of these infants only 3 had blood cultures that were positive for staphylococcus aureus. Of the remaining 7, 2 had conjunctivitis from which staphylococcus aureus was cultured, 4 had negative cultures and 1 did not have a blood culture done. All patients were diagnosed as having bacterial pneumonia and appeared to respond favourably to antibiotic therapy. The pulmonary abnormalities resolved. The children were clinically well in less than 3 weeks. The author suggests that the miliary pattern is one of the radiological patterns of neonatal pneumonia possibly produced by hematogenous bacterial dissemination. (orig.)

    The aim of this study was to identify factors associated with mortality in intensive care unit patients with Klebsiella pneumoniae carbapenemase-producing K. pneumoniae (KPC-Kp) septic shock. A retrospective analysis of intensive care unit patients with KPC-Kp infection and septic shock observed in a large teaching hospital from November 2010 to December 2014 was performed. A total of 111 patients were included in the study. The most frequent source of infection was unknown-focus bacteraemia in 53 patients (47.7%). The rate of resistance to colistin was 51.3%; 30-day mortality was reported for 44 patients (39.6%). Surviving patients were more frequently treated with an initial therapy (within 24 hours) including two or more antibiotics displaying in vitro activity against the isolated KPC-Kp strain (41.8 vs. 18.1%, p 0.01) and were also more likely to receive a definitive therapy including two or more in vitro active antibiotics (85.1 vs. 15.9%, p isolates was the most important determinant of favourable outcome, whilst isolation of colistin-resistant strains was associated with death in septic patients with KPC-Kp infection.

    2006-08-01

    Full Text Available Background: Community-acquired pneumonia could be a life-threatening condition especially in elderly patients. The factors influencing the outcome in elderly patients are thought to be different from those in young adults. We compared the clinical and paraclinical profiles in elderly and nonelderly patients with community-acquired pneumonias. Methods: In this cross-sectional study, seventy nine patients who were hospitalized with community acquired pneumonia over a period of one year were included. Patients' medical records were reviewed; and data related to comorbid conditions, signs and symptoms, laboratory and radiographic findings were gathered using a checklist. Results: The clinical features, laboratory parameters and complications from pneumonia were almost similar in 41 elderly (group I, age ≥65years and 38 young (group II, age<65years subjects. Delirium was seen more in elderly group (p=0.05. The average body temperature and pulse rate were significantly higher in nonelderly group. Sixty one percent of elderly patients and 21% of young patients have Po2 less than 60 (p=0.02. Smoking (29.1%, neurological disturbances (19%, congestive heart failure (15.2%, chronic obstructive pulmonary disease and diabetes mellitus (13.9% were associated comorbidities in both groups. In non elderly group, immune compromise and IV drug use were more common as underlying comorbid conditions. Two of three mortalities were due to elder patients. Conclusion: Community acquired pneumonia could have more serious clinical and abnormal laboratory features in the elderly than younger patients. Mortality rate may be higher in older patients. Comorbid conditions are frequently seen in both elderly and nonelderly patients with community acquired pneumonia, but IV drug use and immune compromise are more frequent in nonelderly patients.

  14. Clinical features of measles pneumonia in adults

    International Nuclear Information System (INIS)

    The clinical features, chest radiographs and computed tomographic (CT) images were evaluated in 11 cases of serologically proved adult measles complicated with pneumonia (10 were previously healthy and one had sarcoidosis). Pneumonia appeared during the rash period in all cases. Respiratory symptoms were cough (9/11), dyspnea (3/11), and hypoxemia (10/11). Pneumonia manifestations were detected in only 4 cases by chest radiograph; on the other hand, they were seen in all cases by CT scan and consisted of ground-glass opacities (73%), nodular opacities (64%) and consolidation (27%). CT seems to be useful method to detect measles pneumonia if it is suspected. Measles pneumonia in previously healthy patients had a good prognosis, as the hypoxemia disappeared within 6 days in all cases. The sarcoidosis patient showed prolonged pneumonic shadows and period of hypoxemia. Measles pneumonia occurring in a host with cellular immunodeficiency may have a severe clinical course. (author)

    Nosocomial infections are an important cause of preventable morbidity and mortality; they also result in significant socioeconomic cost. Nosocomial pneumonia (NCP) is defined as pneumonia, which occurs 48 hours after hospitalization or after discharge from the hospital. It is the second or third most frequent infection among all hospital acquired infections, and the mortality of NCP is higher than the other hospital acquired infections. Patients, diagnosed as NCP were retrospectively analyzed in order to detect microbiological agent and prognostic factors. We evaluated 173 patients, 67.0% of them were male and 33.0% female. Comorbid diseases were present in 94.2% and a medical procedure had been applied in 75.1% of cases. A single agent was isolated in 79.2% of the cases while a mixt infection was present in 13.3%. In 7.5% of the cases, cultures were negative. Endotracheal aspirates were the most common materials (38.9%) used for detected microorganism and sputum cultures were used in 16.8% of the cases. Most commonly encountered microorganism were Pseudomonas aeruginosa, Acinetobacter spp. and Staphylococcus aureus respectively. NCP developed on approximately 18th day of hospitalization. Overall mortality rate was 45.2%. The effects of diabetes mellitus and chronic pulmonary diseases on mortality rate were analized by logistic regression analysis and it's evaluated that the mortality rates increase 3.7 times with diabetes mellitus and 2.4 times with chronic pulmonary diseases. There was no effect of mechanical ventilation history on mortality.

We comprehensively applied modern and traditional laboratory diagnostic techniques to identify microbiota in patients who were admitted to or developed pneumonia in intensive care units (ICUs. During a three-year period, we tested the bronchoalveolar lavage (BAL of patients with ventilator-associated pneumonia, community-acquired pneumonia, non-ventilator ICU pneumonia and aspiration pneumonia, and compared the results with those from patients without pneumonia (controls. Samples were tested by amplification of 16S rDNA, 18S rDNA genes followed by cloning and sequencing and by PCR to target specific pathogens. We also included culture, amoeba co-culture, detection of antibodies to selected agents and urinary antigen tests. Based on molecular testing, we identified a wide repertoire of 160 bacterial species of which 73 have not been previously reported in pneumonia. Moreover, we found 37 putative new bacterial phylotypes with a 16S rDNA gene divergence ≥ 98% from known phylotypes. We also identified 24 fungal species of which 6 have not been previously reported in pneumonia and 7 viruses. Patients can present up to 16 different microorganisms in a single BAL (mean ± SD; 3.77 ± 2.93. Some pathogens considered to be typical for ICU pneumonia such as Pseudomonas aeruginosa and Streptococcus species can be detected as commonly in controls as in pneumonia patients which strikingly highlights the existence of a core pulmonary microbiota. Differences in the microbiota of different forms of pneumonia were documented.

    Full Text Available Background: Diarrhea still continues to be a leading cause of childhood morbidity and mortality and holds the second rank (after pneumonia for mortality in children < 5 years of age. The majority of these deaths can be avoided by timely intervention. The knowledge of caretakers about the severity of diarrheal illness ultimately affects the choice for childcare practices and influences the type of therapies received.  Objectives: To assess the various aspect of maternal knowledge about diarrhea in under-five age children. To determine the child care practices of mothers during diarrheal episodes.Materials and methods: A cross-sectional survey was carried out from February to May 2014. 5 villages were selected by systematic random sampling method in rural field training area of medical college. A self-designed and pre-tested structured questionnaire was used as study tool which covers different aspect of knowledge and childcare practices by mothers/caretakers regarding diarrhea. Overall responses of participants were scored as good, average and poor for assessment of knowledge and practice.  Results: Total 972 mother/caretakers were interviewed. Most of the mothers/caretakers (62.1% were in favor of giving of breast milk as preferred oral fluid during diarrheal episode. Nearly one fourth of mothers/caretakers (26.1% identify symptoms and signs of "dehydration" and the need for consultation. During diarrheal episodes less amount of food and fluid was given by 49.9% and 20.4% mothers/caretaker respectively. The higher level educated and employed mothers had better practices (P < 0.001 Conclusion: The study showed that knowledge and childcare practices for diarrhea still remains a great challenge among the rural population. This could be only deals with improvement in female literacy and to develop and implement diarrhea related educational interventions for mothers/caretakers.

  7. Aspiration pneumonia in patients with cleft palate

    International Nuclear Information System (INIS)

    To assess the incidence of aspiration pneumonia in infants with cleft palate and to compare the incidence between complete and incomplete types of cleft palate. A review of medical records revealed 100 infants who had undergone initial surgery to repair cleft palate in our hospital during a recent three-year period. Aspiration pneumonia was defined as the coexistence of pneumonia at chest radiography with a history of frequent choking during feeding. The anatomic distribution of aspiration pneumonia was analyzed, and the incidences of aspiration pneumonia in infants with complete and incomplete cleft palate were compared. Among 100 children, aspiration pneumonia was found in 35 (35%). Those with complete and incomplete cleft palate showed similar incidences of the condition (27 of 70 [39%] vs 8 of 30 [27%], p=0.36). Pneumonia was most commonly seen in the left lower lobe (11 of 35), followed by the right upper and lower lobes. Aspiration pneumonia is frequently associated with infants with cleft palate. There is no statistical difference in the incidence of aspiration pneumonia between the complete and the incomplete cleft palate group

    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.

    Introduction Pneumonia is common presentation in the emergency room and is still a cause of morbidity and mortality. The rationale of this study was to test the trend of paediatricians to achieve rapid response facing severe pneumonia, the lack of agreed on plan for the management of community acquired pneumonia (CAP) and the few experiences regarding injectable form of β-lactam antimicrobial. Materials and Methods This is a prospective case control study, purposive randomized sampling, three patients were excluded since their information was incomplete, 132 patients were randomly divided into groups, one group named control group (penicillin according to the guidelines of WHO 2013), 33 patients; second group treated by β-lactam inhibitors (Augmentin IV) 50 patients; and third group treated by 3rd generation cephalosporin (ceftriaxone) 49 patients. The study was conducted at the main tertiary care and paediatrics teaching hospital in Khartoum capital of Sudan. The study was completed within the duration from 2010 to 2011. Results Both group showed more or less similar results regarding response, as well as the failure rate however, the Augmentin and ceftriaxone groups showed a little bit better survival than the control group. Conclusion Antibiotics decrease the mortality rate among the pneumonia patients provided that it is given early in the disease. PMID:27437318

    Full Text Available Anil Mor, Sinna P Ulrichsen, Elisabeth Svensson, Klara Berencsi, Reimar W Thomsen Department of Clinical Epidemiology, Institute of Clinical Medicine, Aarhus University Hospital, Aarhus, Denmark Background: To reduce the increasing burden of pneumonia hospitalizations, we need to understand their determinants. Being married may decrease the risk of severe infections, due to better social support and healthier lifestyle. Patients and methods: In this population-based case-control study, we identified all adult patients with a first-time pneumonia-related hospitalization between 1994 and 2008 in Northern Denmark. For each case, ten sex- and age-matched population controls were selected from Denmark's Civil Registration System. We performed conditional logistic regression analysis to estimate the odds ratios (ORs for pneumonia hospitalization among persons who were divorced, widowed, or never married, as compared with married persons, adjusting for age, sex, 19 different comorbidities, alcoholism-related conditions, immunosuppressant use, urbanization, and living with small children. Results: The study included 67,162 patients with a pneumonia-related hospitalization and 671,620 matched population controls. Compared with controls, the pneumonia patients were more likely to be divorced (10% versus 7% or never married (13% versus 11%. Divorced and never-married patients were much more likely to have previous diagnoses of alcoholism-related conditions (18% and 11%, respectively compared with married (3% and widowed (6% patients. The adjusted OR for pneumonia-related hospitalization was increased, at 1.29 (95% confidence interval [CI]: 1.25-1.33 among divorced; 1.15 (95% CI: 1.12-1.17 among widowed; and 1.33 (95% CI: 1.29-1.37 among never-married individuals as compared with those who were married. Conclusion: Married individuals have a decreased risk of being hospitalized with pneumonia compared with never-married, divorced, and widowed patients

  12. Antimicrobial treatment of nosocomial meticillin-resistant Staphylococcus aureus (MRSA) pneumonia: current and future options.

    Welte, Tobias; Pletz, Mathias W

    2010-11-01

    Meticillin-resistant Staphylococcus aureus (MRSA) is a frequent cause of nosocomial pneumonia. Inadequate or inappropriate antimicrobial therapy, often caused by antimicrobial resistance, is associated with increased mortality for these infections. Agents currently recommended for the treatment of MRSA pneumonia include vancomycin and linezolid in the USA, and vancomycin, linezolid, teicoplanin and quinupristin/dalfopristin in Europe. Antimicrobials such as tigecycline and daptomycin, although approved for the treatment of some MRSA infections, have not demonstrated efficacy equivalent to the approved agents for MRSA pneumonia. Further agents lack data from randomised controlled trials (e.g. fosfomycin, fusidic acid or rifampicin in combination with vancomycin). Antimicrobial agents that have recently been approved or are being investigated as treatments for MRSA infections include the lipoglycopeptides telavancin (approved for the treatment of complicated skin and skin-structure infections in the USA and Canada), dalbavancin and oritavancin, the cephalosporins ceftobiprole and ceftaroline, and the dihydrofolate reductase inhibitor iclaprim. To be an effective treatment for MRSA pneumonia, antimicrobial agents must have activity against antimicrobial-resistant S. aureus, penetrate well into the lung, have a low potential for resistance development and have a good safety profile. Here, the available data for current and potential future MRSA pneumonia antimicrobials are reviewed and discussed. PMID:20724119

    Full Text Available Bacteremia, the presence of viable bacteria in the blood stream, is often associated with several clinical conditions. Bacteremia can lead to multiple organ failure if managed incorrectly, which makes providing suitable nutritional support vital for reducing bacteremia-associated mortality. In order to provide such information, we investigated the metabolic consequences of a Klebsiella pneumoniae (K. pneumoniae infection in vivo by employing a combination of (1H nuclear magnetic resonance spectroscopy and multivariate data analysis. K. pneumoniae was intravenously infused in rats; urine and plasma samples were collected at different time intervals. We found that K. pneumoniae-induced bacteremia stimulated glycolysis and the tricarboxylic acid cycle and also promoted oxidation of fatty acids and creatine phosphate to facilitate the energy-demanding host response. In addition, K. pneumoniae bacteremia also induced anti-endotoxin, anti-inflammatory and anti-oxidization responses in the host. Furthermore, bacteremia could cause a disturbance in the gut microbiotal functions as suggested by alterations in a range of amines and bacteria-host co-metabolites. Our results suggest that supplementation with glucose and a high-fat and choline-rich diet could ameliorate the burdens associated with bacteremia. Our research provides underlying pathological processes of bacteremia and a better understanding of the clinical and biochemical manifestations of bacteremia.

Pneumonia was frequent in first-time exacerbations (36.1%, but declined in successive exacerbations to 25.6% by the seventh or greater exacerbation. Pneumonic COPD exacerbations increased 20% from 0.92 per 1,000 population in 2006 to 1.10 per 1,000 population in 2012. Nonpneumonic exacerbations decreased by 6% from 1.74 per 1,000 population to 1.63 per 1,000 population during the same period. A number of markers of health resource utilization were more prevalent in pneumonic exacerbations than in nonpneumonic exacerbations: length of stay (median 7 vs 4 days, intensive care unit admission (7.7% vs 12.5%, and several acute procedures. Thirty-day mortality was 12.1% in first-time pneumonic COPD exacerbations versus 8.3% in first-time nonpneumonic cases (adjusted HR [aHR] 1.20, 95% confidence interval [CI] 1.17–1.24. Pneumonia also predicted increased mortality associated with a second exacerbation (aHR 1.14, 95% CI 1.11–1.18, and up to a seventh or greater exacerbation (aHR 1.10, 95% CI 1.07–1.13.

    Full Text Available A pneumonia necrosante é uma patologia grave que surge como complicação rara de pneumonia lobar. Quatro crianças na faixa etária entre dez e 28 meses foram hospitalizadas com pneumonia bacteriana aguda, evoluindo com toxemia, derrame pleural e insuficiência respiratória, respondendo insatisfatoriamente a antibioticoterapia e drenagem pleural. Todos os pacientes foram submetidos a tratamento cirúrgico para descorticação pulmonar e ressecção de tecido pulmonar necrosado. Complicações como fístulas broncopleurais ocorreram em dois pacientes, havendo óbito em um dos casos. Os autores concluem que a ressecção pulmonar de emergência é indicada quando a necrose pulmonar é diagnosticada em pacientes septicêmicos ou com fístula broncopleural de alto débito, visando a melhora do prognóstico dessas crianças, mesmo cientes de que o índice de morbimortalidade nesses casos é alto.Necrotizing pneumonia is a serious complication of lobar pneumonia. Four children aged between ten months and three years were admitted with acute bacteremic pneumonia and developed sepsis, pleural effusion, and respiratory distress despite adequate antibiotic treatment and chest tube drainage. Decortication and pulmonary resection were performed in all of them. The observed complications were bronchopleural fistula and one death. The emergency pulmonary resection is indicated when pulmonary necrosis is associated to sepsis and massive bronchopleural fistula. In such circumstances, morbidity and mortality are higher than in other conditions.

    2016-08-01

    Respiratory syncytial virus (RSV) is the most important viral cause of pneumonia in early childhood (ie, younger than 2 years), responsible for high infant morbidity and mortality worldwide. It is widely accepted that an effective vaccine against RSV would have a major impact on child health globally. Despite the setbacks of the clinical trials in the 1960s, there has been a recent and significant revival of interest in vaccines against RSV, with several promising candidates undergoing evaluation. In this Review, we describe the epidemiological and immunological background to RSV infection and subsequently focus on the promising pipeline of RSV vaccine development. We discuss the potential for implementation of a safe and immunogenic RSV vaccine within the context of global health and with regards to a range of strategies, including vaccination of women during pregnancy, which is likely to emerge as a beneficial and feasible public health tool. This approach would provide interim protection to vulnerable, RSV-naive infants and other high risk groups, in which the burden of admission to hospital and death is greatest. Extending research and implementation from resource-rich to resource-poor settings is required to enhance our understanding of RSV immunity and inform vaccine development and delivery strategies for all settings. We summarise key outstanding issues for researchers and policy makers to understand the interplay of biological and non-biological factors affecting design and distribution of a successful RSV vaccine globally.

  20. Childhood proptosis

    International Nuclear Information System (INIS)

    Proptosis in children is a hallmark of orbital diseases which can present a diagnostic challenge requiring thoughtful investigation. The aim of this review is to provide the reader an overview of the subject of childhood proptosis with an emphasis on the systematic and practical approach for the work-up of proptosis in children. Use of proper imaging studies is essential for the correct diagnosis. Computed tomography is a good screening test for any space occupying lesion of the orbit. Proptosis describes eye prominence due to space occupying orbital lesions. Congenital lesions usually present in the first decade of life. Acquired orbital lesions such as lymphangiomas, orbital varix, rhabdomyosarcoma and neural tumors may present at the end of the first decade of life. Metastatic tumors to the orbit, adenocarcinoma of lacrimal gland and rapidly growing masses may present with proptosis associated with pain. Visual loss can be the presenting symptoms in the patients with optic nerve (ON) gliomas, orbital meningiomas and posteriorly located tumors. Cystic lesions of the orbit may be congenital or acquired, dermoid cysts being the most common congenital orbital lesions. Some of the vascular lesions of the orbit include capillary hemangiomas, lymphangiomas, orbital varix, and arteriovenous malformations. Inflammatory process of the orbit in children include cellulitis and pseudotumor. Neural tumors such as neurofibromas, ON gilomas and meningiomas are less common causes of proptosis in children. Rhabdomyosarcoma is the most common primary orbital malignancy in children which can present with acute proptosis and is one of the few life-threatening diseases seen initially by an ophthalmologist. Secondary orbital tumors invade the orbit from adjacent sinuses, cranium or extended from the eye itself. The most common distant metastases in children include neuroblastoma and Ewing's sarcoma. Although many orbital processes can be diagnosed based on history, clinical

  2. Influenza mortality in the United States, 2009 pandemic: burden, timing and age distribution.

    Ann M Nguyen

    Full Text Available BACKGROUND: In April 2009, the most recent pandemic of influenza A began. We present the first estimates of pandemic mortality based on the newly-released final data on deaths in 2009 and 2010 in the United States. METHODS: We obtained data on influenza and pneumonia deaths from the National Center for Health Statistics (NCHS. Age- and sex-specific death rates, and age-standardized death rates, were calculated. Using negative binomial Serfling-type methods, excess mortality was calculated separately by sex and age groups. RESULTS: In many age groups, observed pneumonia and influenza cause-specific mortality rates in October and November 2009 broke month-specific records since 1959 when the current series of detailed US mortality data began. Compared to the typical pattern of seasonal flu deaths, the 2009 pandemic age-specific mortality, as well as influenza-attributable (excess mortality, skewed much younger. We estimate 2,634 excess pneumonia and influenza deaths in 2009-10; the excess death rate in 2009 was 0.79 per 100,000. CONCLUSIONS: Pandemic influenza mortality skews younger than seasonal influenza. This can be explained by a protective effect due to antigenic cycling. When older cohorts have been previously exposed to a similar antigen, immune memory results in lower death rates at older ages. Age-targeted vaccination of younger people should be considered in future pandemics.

  3. Pneumonia: high-resolution CT findings in 114 patients

    International Nuclear Information System (INIS)

    The objective of the present study was to assess the high-resolution CT appearances of different types of pneumonia. The high-resolution CT scans obtained in 114 patients (58 immunocompetent, 59 immunocompromised) with bacterial, Mycoplasma pneumoniae, viral, fungal, and Pneumocystis carinii pneumonias were analyzed retrospectively by two independent observers for presence, pattern, and distribution of abnormalities. Areas of air-space consolidation were not detected in patients with viral pneumonia and were less frequently seen in patients with Pneumocystis carinii pneumonia (2 of 22 patients, 9%) than in bacterial (30 of 35, 85%), Mycoplasma pneumoniae (22 of 28, 79%), and fungal pneumonias (15 of 20, 75%; p<0.01). There was no significant difference in the prevalence or distribution of consolidation between bacterial, Mycoplasma pneumoniae, and fungal pneumonias. Extensive symmetric bilateral areas of ground-glass attenuation were present in 21 of 22 (95%) patients with Pneumocystis carinii pneumonia and were not seen in other pneumonias except in association with areas of consolidation and nodules. Centrilobular nodules were present less commonly in bacterial pneumonia (6 of 35 patients, 17%) than in Mycoplasma pneumoniae (24 of 28, 96%), viral (7 of 9, 78%), or fungal (12 of 20, 92%) pneumonia (p<0.01). Except for Pneumocystis carinii pneumonia and Mycoplasma pneumoniae pneumonia, which often have a characteristic appearance, high-resolution CT is of limited value in the differential diagnosis of the various types of infective pneumonia.

    Pulmonary fibrosis is the main cause of severe morbidity and mortality in idiopathic interstitial pneumonias (IIP). In the past years, there has been major progress in the discovery of genetic factors that contribute to disease. Genes with highly penetrant mutations or strongly predisposing common risk alleles have been identified in familial and sporadic IIP. This review summarizes genes harbouring causative rare mutations and replicated common predisposing alleles. To date, rare mutations i...

    Streptococcus pneumoniae is a major cause of morbidity and mortality worldwide. Its polysaccharide capsule causes resistance to phagocytosis and interferes with the innate immune system's ability to clear infections at an early stage. Nevertheless, we found that encapsulated pneumococci are sensitive to killing by a human neutrophil granule extract. We fractionated the extract by high-performance liquid chromatography and identified α-defensins by mass spectrometry as the proteins responsible...

    Introduction It has been suggested that delayed intensive care unit (ICU) transfer is associated with increased mortality for patients with community-acquired pneumonia (CAP). However, ICU admission policies and patient epidemiology vary widely across the world depending on local hospital practices and organizational constraints. We hypothesized that the time from the onset of CAP symptoms to invasive mechanical ventilation could be a relevant prognostic factor. Methods One hundred patients w...

    Tuberculosis (TB) is an uncommon cause of severe respiratory failure, even in highly endemic regions. Mortality in cases requiring mechanical ventilation (MV) varies between 60 and 90%. The use of extracorporeal membrane oxygenation (ECMO) is not frequently needed in TB. We report the case of a 24 year old woman diagnosed with bilateral pneumonia that required MV and intensive care, patient was managed with prone ventilation for 48 h, but persisted in refractory hypoxemia.

    Full Text Available Abstract Background Patients hospitalized with community acquired pneumonia (CAP have a substantial risk of death, but there is evidence that adherence to certain processes of care, including antibiotic administration within 8 hours, can decrease this risk. Although national mortality data shows blacks have a substantially increased odds of death due to pneumonia as compared to whites previous studies of short-term mortality have found decreased mortality for blacks. Therefore we examined pneumonia-related processes of care and short-term mortality in a population of patients hospitalized with CAP. Methods We reviewed the records of all identified Medicare beneficiaries hospitalized for pneumonia between 10/1/1998 and 9/30/1999 at one of 101 Pennsylvania hospitals, and randomly selected 60 patients at each hospital for inclusion. We reviewed the medical records to gather process measures of quality, pneumonia severity and demographics. We used Medicare administrative data to identify 30-day mortality. Because only a small proportion of the study population was black, we included all 240 black patients and randomly selected 720 white patients matched on age and gender. We performed a resampling of the white patients 10 times. Results Males were 43% of the cohort, and the median age was 76 years. After controlling for potential confounders, blacks were less likely to receive antibiotics within 8 hours (odds ratio with 95% confidence interval 0.6, 0.4–0.97, but were as likely as whites to have blood cultures obtained prior to receiving antibiotics (0.7, 0.3–1.5, to have oxygenation assessed within 24 hours of presentation (1.6, 0.9–3.0, and to receive guideline concordant antibiotics (OR 0.9, 0.6–1.7. Black patients had a trend towards decreased 30-day mortality (0.4, 0.2 to 1.0. Conclusion Although blacks were less likely to receive optimal care, our findings are consistent with other studies that suggest better risk-adjusted survival

  16. Causes of mortality and development: Evidence from large health shocks in 20th century America

    DEFF Research Database (Denmark)

    Worm Hansen, Casper

    Exploiting pre-intervention variation in flu/pneumonia, tuberculosis and maternal mortality, together with time variation arising from medical breakthroughs starting in the late 1930s, this paper studies the aggregate impact of large health shocks across US states. The analysis demonstrates......, the decline in maternal mortality has a fragile, but positive relationship with income per capita. Because these specific health shocks affected mortality across the life cycle differently, the evidence here underscores the general tenet of regarding health as multifaceted....... that the shocks influenced income per capita in different ways. While the shock to flu/pneumonia mortality has been conductive for development, the large reduction in the incidence of tuberculosis deaths has been a negative force in the development of US states over the second-half of 20th century. In addition...

    Full Text Available Abstract Background Patients with Parkinson's disease have an elevated risk of pneumonia and randomized trials suggest that this risk may be increased with the dopamine agonist pramipexole. It is uncertain whether pramipexole or other dopamine agonists increase the risk of pneumonia. Methods We used the United Kingdom's General Practice Research Database (GPRD to identify users of anti-parkinsonian drugs, 40–89 years of age, between 1997 and 2009. Using a nested case–control approach, all incident cases hospitalised for pneumonia were matched with up to ten controls selected among the cohort members. Rate ratios (RR and 95% confidence intervals (CI of pneumonia associated with current use of dopamine agonists were estimated using conditional logistic regression, adjusted for covariates. Results The cohort included 13,183 users of anti-parkinsonian drugs, with 1,835 newly diagnosed with pneumonia during follow-up (rate 40.9 per 1,000 per year. The rate of pneumonia was not increased with the current use of pramipexole (RR 0.76; 95% CI: 0.57-1.02, compared with no use. The use of pramipexole was not associated with an increased rate of pneumonia when compared with all other dopamine agonists collectively (RR 0.85; 95% CI: 0.62-1.17. Conclusions The use of pramipexole does not appear to increase the risk of pneumonia.

  19. Microbiological pattern of ventilator associated pneumonia

    International Nuclear Information System (INIS)

    Ventilator associated pneumonia (VAP) is an important and common complication of mechanically ventilated patients. It is the leading cause of morbidity and mortality in Intensive Care Units (ICU) worldwide. The aim of study was to determine the pattern of bacteria involved in VAP in intensive care unit of Jinnah hospital Lahore. Methods: It was descriptive case series study, conducted over a period of one year on mechanically ventilated 50 patients. American Thoracic Society (ATS) guidelines recommend quantitative/semi-quantitative culture of endotracheal aspirates (ETA) or bronchoscopic aspirates/washing from the infected lung segments for the diagnosis of VAP. Hence this study was conducted to identify the types of bacteria involved in VAP in our ICU. Patients enrolled were clinically and radiologically suspected VAP, admitted in the ICU of Jinnah Hospital/Allama Iqbal Medical College (AIMC) Lahore. Bronchial washings were taken with the help of Fiber optic bronchoscope. Wherever bronchoscopy was not possible, subglottic secretions were collected with the help of sterilized catheter and sucker. Collected samples were sent to the Pathology laboratory of AIMC for aerobic culture and sensitivity. Results: Major pathogenic bacteria isolated were Gram negative (74%). Among this group E. coli, Pseudomonas, Klebsiella and Acinetobacter were the commonest organisms. Gram positive bacteria were 20%, Staphylococcus aureus (MRSA) and haemolyticus streptococci were the major isolate. In 4% cases mixed growth and in 2% cases no growth was reported. Conclusion: Major pathogenic organisms of VAP in our ICU are Gram negative bacteria. The Bacteriological culture of endobroncheal aspirates is helpful in the diagnosis and management of VAP. Emperic antibiotic therapy for VAP should cover Gram negative organisms. (author)
