    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

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

    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.

  7. 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.

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

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

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

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

    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.

    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.

    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.

    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.

    Incidence rates of childhood leukemia vary between different regions of the world. The objective of this study was to test possible trends in incidence rate of early childhood leukemia (children leukemia was 61 per million. The AAIR for acute lymphoid leukemia (ALL) was 44 per million and nonlymphoid acute leukemia (NLAL) was 14 per million. The median ALL/NLAL ratio was 3.0, suggesting higher incidence rate of NLAL in these settings. The joinpoint analysis demonstrated increased leukemia incidence rate in João Pessoa (AAPC = 20; 95% CI: 3.5, 39.4) and Salvador (AAPC = 8.68; 95% CI: 1.0, 16.9), respectively, whereas incidence rate in São Paulo PBCR decreased (AAPC = -4.02%; 95% CI: -6.1%, -1.9%). Correlation between ALL AAIR and selected variables of socioeconomic (SES) factors was not observed. Increased AAIR regionally overtime was observed. However, the interpretation for such phenomenon should be cautious because it might reflect the access to health care, diagnosis procedures, and improvement of PBCR´s quality. The observed trend supports the necessity of further ecological studies. PMID:26925506

  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.

    Amy Sarah Ginsburg

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

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

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

  4. 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 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.

    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.

    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...

  10. 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

    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.

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

    Full Text Available 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.

  2. Further statement on the incidence of childhood cancer in Wales

    International Nuclear Information System (INIS)

    In March 1999 the Welsh Office asked COMARE to examine two unpublished studies. The first by Busby et al of ''Green Audit'' concluded that there was a significant excess of childhood leukaemia in North Wales associated with residential proximity to the coast. The second study, carried out by Steward et al of the Welsh Cancer Intelligence and Surveillance Unit (WCISU), did not support this conclusion. We were asked to advise as to whether we considered that there was a real raised incidence of childhood leukaemia near the coast of North Wales and whether further study was required. To do this we initially organised a comparison of the figures quoted by both the Green Audit and WCISU with the database held by the Childhood Cancer Research Group (CCRG) in Oxford. This group maintains the National Registry of Childhood Tumours (NRCT), data for which are supplied from a variety of sources including cancer registries but also directly from medical cancer specialists as well as from death certificates. As a consequence this provides an independent check on much of the data on childhood cancer held by cancer registries in Great Britain and is clinically validated. After carrying out the independent check on the number of cases of childhood leukaemia in these Welsh counties it was immediately apparent that the data held by Green Audit, on which the analysis by Busby et al was based, were incorrect. These data were received from the Welsh Cancer Registry (WCR) in 1995. A further data set was received from WCR in 1996 but was not used in the analysis by Busby et al. In June 1999 we issued a statement to the Welsh Office. In that statement we noted that Dr Busby and his colleagues appeared to have used erroneous data in their study. On the basis of the Steward et al data, COMARE also stated that we found no evidence to support the contention that there is an increased incidence of childhood leukaemia or other childhood cancers amongst the Welsh population living close to the

    Between September 1, 1981, and August 31, 1982, all patients with suspected or confirmed pneumonia among the 46,979 inhabitants of four municipalities in the province of Kuopio, Finland, were reported to a pneumonia register by their attending physicians. In addition, two study pathologists reported all cases of pneumonia found at autopsy, and two permanent registers were checked for retrospective identification of patients. Chest radiographs were obtained from 97% of all patients. The final diagnosis was based on radiologic or autopsy criteria. A total 546 patients (323 males and 223 females) had community-acquired pneumonia; of these, 37% were less than 15 years of age, and 31% were 60 years of age or older. Nineteen percent of the patients had defined chronic conditions, and 42% were admitted to hospital. The case fatality rate was 4%. The overall incidence of community-acquired pneumonia per 1,000 inhabitants per year was 11.6 (13.9 in males, 9.4 in females). The age-specific incidence per 1,000 inhabitants per year was as follows: age or = 75 years, 34.2. PMID:8317455

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

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

  10. Disseminated dendriform pulmonary ossification associated with usual interstitial pneumonia: incidence and thin-section CT-pathologic correlation

    International Nuclear Information System (INIS)

    The aim of this work was to assess the incidence of disseminated pulmonary dendriform ossification in usual interstitial pneumonia and nonspecific interstitial pneumonia, and to correlate thin-section computed tomography (CT) and histopathologic findings. We retrospectively reviewed thin-section CT and pathologic specimens of biopsy-proven usual interstitial pneumonia (75 patients, 57 men and 18 women, mean age 60 years, range 29-83 years) and nonspecific interstitial pneumonia (44 patients, 9 men and 35 women, mean age 55 years, range 20-73 years). On review of CT and histopathologic specimens, diffuse dendriform ossification was identified in five (four men and one woman, age range 41-68 years, mean 58 years) of 75 patients (6.7%) with usual interstitial pneumonia. It was not seen in any of 44 patients with nonspecific interstitial pneumonia. With thin-section CT (osteoporosis window; window width 818, level 273), disseminated dendriform pulmonary ossification was detected as multiple tiny calcifications in bibasilar subpleural lungs (100% sensitive and 100% specific when compared with histopathologic findings as the gold standard). The thin-section CT finding of multiple tiny calcifications in bibasilar subpleural lungs might be of some help in the differential diagnosis between usual interstitial pneumonia and nonspecific interstitial pneumonia, considering they were not seen in any patients with nonspecific interstitial pneumonia (0%, 0/44) in our series.

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

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

  19. Incidence of pneumonia and risk factors among patients with head and neck cancer undergoing radiotherapy

    International Nuclear Information System (INIS)

    This study investigated the incidence and patient- and treatment-related risk factors related to pneumonia acquired during radiotherapy (PNRT) in head and neck cancer (HNC) patients. Using the universal insurance claims data, 15,894 total HNC patients between 1998 and 2007 were included in this analysis. PNRT was defined as the occurrence of pneumonia within 90 days of the commencement of radiotherapy. Information also included some demographic characteristics, treatment-related factors, and comorbidities. Appropriate statistical tests were performed to assess the difference between patients with and those without PNRT. A logistic regression was used to estimate the odds ratio (OR) of PNRT among the variables examined. In total, 772 patients (4.86%) were identified with PNRT as the case group, whereas 15,122 subjects of the same cancer without PNRT formed the control group. Of patients with PNRT, 632 (81.9%) were hospitalized with a mean length of stay of 25.9 days. Results from the multiple logistic regression showed that an older age and certain comorbidities were associated with an increased risk of PNRT. Patients with cancer of the tongue, buccal mucosa, oropharynx, and hypopharynx/larynx were at particularly higher risk (OR = 1.28, 1.28, 1.67, and 1.74, respectively). Compared to radiotherapy alone, concurrent chemoradiotherapy had no effect on the PNRT. Patients in the PNRT group had higher overall medical costs and length of stay. The incidence of PNRT in HNC patients receiving radiotherapy was approximately 5%. Notably, an older age, certain comorbidities, and certain specific tumor sites were associated with an increased risk

    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.

    Background Data on childhood and adolescent malignant tumors incidence are skimp in developing countries. In this study, we analyzed the incidence and trend of childhood and adolescent cancers in Yazd city, center of Iran between Jan 2004 and Dec 2013. Material and Methods The various types of malignant tumors were grouped pursuant to the International Classification for Cancer in Children. To analyze the data, descriptive and illative statistical methods were used. Results Two hundred twenty-two patients with a malignancy aged less than 18 years were studied with a male to female ratio of 1.36.The mean age of patients was 9.88 (±5.7) years. Leukemia with the frequency of 84 (37.8%) and after that lymphoid malignancies with the frequency of 49 (22.1%) were the most common cancers. There was a low range of oscillation in the incidence rate of malignancies during this period of time (P value= 0.081). Malignancies were mostly in males (P value=0.057) but the whole process of malignancy incidence had gone toward the higher rate of incidence in females. Incidence rate of cancers types was steady. Malignancy incidence was 3-7 cases in hundred of thousands except a year of which this incidence rate was estimated 13.4. Conclusion Leukemias and lymphomas were the main cancers in the center of Iran. Childhood and adolescent malignancies may be considerably under-recorded in our province .A childhood and adolescent cancer registry is necessary for exact analysis of these types of malignancies.

    Shameq Sayeed

    Full Text Available BACKGROUND: South Asians in England have an increased risk of childhood cancer but incidence by their individual ethnicities using self-assigned ethnicity is unknown. Our objective was to compare the incidence of childhood cancer in British Indians and Whites in Leicester, which has virtually complete, self-assigned, ethnicity data and the largest population of Indians in England. METHODS: We obtained data on all cancer registrations from 1996 to 2008 for Leicester with ethnicity obtained by linkage to the Hospital Episodes Statistics database. Age-standardised incidence rates were calculated for childhood cancers in Indians and Whites as well as rate ratios, adjusted for age. RESULTS: There were 33 cancers registered among Indian children and 39 among White children. The incidence rate for Indians was greater compared to Whites for all cancers combined (RR 1.82 (95% CI 1.14 to 2.89; p = 0.01, with some evidence of increased risk of leukaemia (RR 2.20 (0.95 to 5.07; p = 0.07, lymphoma (RR 3.96 (0.99 to 15.84; p = 0.04 and central nervous system tumours (RR 2.70 (1.00 to 7.26; p = 0.05. Rates were also higher in British Indian children compared to children in India. CONCLUSIONS: British Indian children in Leicester had an increased risk of developing cancer compared to White children, largely due to a higher incidence of central nervous system and haematological malignancies.

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

    Thyroid cancer incidence was studied in the cohort of residents of Ozyorsk and Kyshtym, the nearest upwind cities to the Mayak Production Association (Mayak PA), Russia's first plutonium production facility, which has been in operation since 1948. Radioactive contamination of areas around the Mayak PA were from unmonitored releases of inert gases produced by industrial reactors and also from the release of uranium fission products from a radiochemical plant stack where irradiated uranium blocks were refined. Iodine-131 (131I) was the main contributor to the technogenic dose from atmospheric releases. Routine monitoring of gaseous releases began in the mid-1960s, when a gas purification system was perfected. Children were a critical group due to their higher radiosensitivity and specific diet (dairy products and vegetables). Both cities maintain Registries containing over 100,000 individuals born from 1934-2006. Among this group, more than 100 cases of thyroid cancer were registered during 1948-2009. The relative risk of thyroid cancer incidence is 1.5 times higher than in the Chelyabinsk. PMID:22647908

    The purpose of this study was to determine the factors related to the need for cooperation with child guidance centers with a focus on the presence or absence of a history of childhood problems in at-risk parents receiving support from their municipality. Among the 1890 parents who received child care support from public health nurses in the municipalities, 164 parents (8.7%) had a history of childhood problems. Among these, 50 parents (30.5%) received support from child guidance centers. The parents with a history of childhood problems had a higher incidence rate for receiving support from child guidance centers than other parents. Multiple logistic regression analysis showed that "marital strife or domestic violence", and "financial problems" were associated with consultations with child guidance centers among parents with a history of childhood problems. The results showed that family situations of parents who had a history of childhood problems may, in time, become more severe, even if they have received support from public health nurses in the municipalities. Therefore, parents with a history of childhood problems need support as early as possible. In addition, those parents with "marital strife or domestic violence" and "financial problems" also need guidance and early nursing care interventions. J. Med. Invest. 63: 209-215, August, 2016.

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

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

    Full Text Available There is warranted interest in assessing the association between residential radon exposure and the risk of childhood cancer. We sought to evaluate the association between residential radon exposure and the incidence of childhood lymphoma in Texas. The Texas Cancer Registry (n = 2147 provided case information for the period 1995–2011. Denominator data were obtained from the United States Census. Regional arithmetic mean radon concentrations were obtained from the Texas Indoor Radon Survey and linked to residence at diagnosis. Exposure was assessed categorically: ≤25th percentile (reference, >25th to ≤50th percentile, >50th to ≤75th percentile, and >75th percentile. Negative binomial regression generated adjusted incidence rate ratios (aIRR and 95% confidence intervals (CI. We evaluated lymphoma overall and by subtype: Hodgkin (HL; n = 1248, Non-Hodgkin excluding Burkitt (non-BL NHL; n = 658, Burkitt (BL; n = 241, and Diffuse Large B-cell (DLBCL; n = 315. There was no evidence that residential radon exposure was positively associated with lymphoma overall, HL, or BL. Areas with radon concentrations >75th percentile had a marginal increase in DLBCL incidence (aIRR = 1.73, 95% CI: 1.03–2.91. In one of the largest studies of residential radon exposure and the incidence of childhood lymphoma, we found little evidence to suggest a positive or negative association; an observation consistent with previous studies.

    Full Text Available Many hospitalizations for asthma could potentially be avoided with appropriate management. The aim of this study was to analyze data on disease management of a paediatric population with a hospitalization for asthma. The study population comprised 6-17 year old subjects belonging to three local health units of the Lombardy Region, northern Italy. Regional administrative databases were used to collect data on: the number of children with an incident hospitalization for asthma during the 2004-2006 period, anti-asthma therapy, specialist visit referrals, and claims for spirometry, released in the 12 months before and after hospitalization. Each patient's asthma management profile was compared with GINA guideline recommendations. Among the 183 hospitalized subjects, 101 (55% received therapy before hospitalization and 82 (45% did not. 10% did not receive any therapy either before or after hospital admission and in 13% the therapy was discontinued afterward. Based on GINA guidelines, asthma management adhered to recommendations only for 55% of subjects. Results may suggest that for half of hospitalized subjects, inaccurate diagnosis, under-treatment/scarce compliance with asthma guidelines by physicians, and/or scarce compliance to therapy by patients/their parents occurred. In all these cases, hospitalization would be a proxy indicator of preventable poor control of disease, rather than a proxy indicator of severity.

    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

    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.

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

    Objective Previous research has suggested that childhood emotional abuse, physical abuse, and sexual abuse are associated with an increased risk for ischemic heart disease. Our objective was to examine whether childhood abuse predicted incident metabolic syndrome, a precursor to heart disease, in mid-life women. Methods Participants were 342 (114 Black, 228 White) women from the Pittsburgh site of the Study of Women’s Health Across the Nation (SWAN). SWAN included a baseline assessment of premenopausal or early perimenopausal women in midlife (mean age = 45.7), and women were evaluated for presence of the metabolic syndrome over 7 annual follow-up visits. Women were classified as having metabolic syndrome if they met 3 of the following criteria: waist circumference > 88 cm, triglycerides ≥ 150 mg/dl, HDL < 50 mg/dl, SBP ≥ 130 or DBP ≥ 85 mmHg or on blood pressure medication, and fasting glucose ≥ 110 mg/dl or diabetic. The Childhood Trauma Questionnaire is a standardized measure that retrospectively assesses three domains of abuse in childhood and adolescence: emotional, physical, and sexual abuse. Results Approximately 34% of the participants reported a history of abuse. Cox model survival analysis showed that physical abuse was associated with incident metabolic syndrome over the course of seven years (HR = 2.12, p = .02), adjusted for ethnicity, age at baseline, and time-dependent menopausal status. Sexual abuse and emotional abuse were unrelated to the metabolic syndrome. Conclusion This is the first study to show that a history of childhood abuse, specifically physical abuse, is related to the development of metabolic syndrome in mid-life women. PMID:22775234

    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.

    Full Text Available The effects of pre- or postnatal passive smoking on the adult incidence of asthma have not been reported previously. Between 1985 and 1996/1997, we conducted an 11-year community cohort study on the incidence of asthma and respiratory symptoms in Western Norway. The cohort included 3,786 subjects aged 15 to 70 years, of which 2,819 were responders at both baseline and follow-up. The incidence of asthma and five respiratory symptoms by self-reported exposure to maternal smoking in utero and in childhood, as well as smoking by other household members in childhood, was examined. After adjustment for sex, age, education, hay fever, personal smoking, and occupational exposure, maternal smoking was associated with asthma, phlegm cough, chronic cough, dyspnoea grade 2, attacks of dyspnoea, and wheezing, with odds ratios (95% confidence intervals [CI] of 3.0 (1.6, 5.6, 1.7 (1.1, 2.6, 1.9 (1.2, 3.0, 1.9 (1.2, 3.0, 2.0 (1.3, 3.0, and 1.4 (0.9, 2.2, respectively.

Exposure to pre- and postnatal smoking carries a substantial risk for developing adult asthma and respiratory symptoms.

  10. Incidence of childhood leukemia in relation to proximity and general characteristics of different environmental exposure sources

    International Nuclear Information System (INIS)

    The role of the environment in the etiology of childhood acute leukemia (AL) is currently investigated. In this context, the aim of the present work is to study the association between the incidence of AL and the proximity of nuclear power plants (NPP) and to high voltage overhead power lines (HV OLs). At first, the geographical variations of AL have been studied at the Departement level. The cases included in the studies are all cases of AL of the French National Registry of Childhood Haemopatopoietic Malignancies on the studied periods: 1990-2004 for the study of incidence on Departements and 2002-2007 for the studies of association between incidence of AL and environmental exposure factors. Concerning those latter studies, a case-control approach has been used. The control sample, representative of the French pediatric population, contains 30,000 subjects and has been drawn by the INSEE. The precise localization of addresses of subjects and of exposure sources in relation with the type of sources is essential to build indicators of exposure reflecting the probability and intensity of exposure. * The study of AL by Departement has highlighted neither trend nor spatial structure in the incidence at this geographical level globally as well as by age, gender and subtype of leukemia.* On 2002-2007, on the contrary of on previous periods, the incidence of AL at less than 5 km from a NPP was nearly twice higher than expected, with the case-control study as well as with the incidence approach. This result was not specific to any age group, NPP, a type of NPP and was not associated with the geographic zoning of gaseous discharges of NPPs. * The study of the proximity to HV OLs highlighted an association between the incidence of AL and the close proximity (≤ 50 m) of lines of more than 225 kV, association which was restricted to children of less than 5 y.o. or living in non-urban areas; but not with the proximity to lines of less than 150 kV.

    2004-01-01

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

    1995-12-31

    This paper describes an analysis of the geographical variation of childhood leukaemia incidence in Great Britain over a 15 year period in relation to natural radiation (gamma and radon). Data at the level of the 459 district level local authorities in England, Wales and regional districts in Scotland are analysed in two complementary ways: first, by Poisson regressions with the inclusion of environmental covariates and a smooth spatial structure; secondly, by a hierarchical Bayesian model in which extra-Poisson variability is modelled explicitly in terms of spatial and non-spatial components. From this analysis, we deduce a strong indication that a main part of the variability is accounted for by a local neighbourhood `clustering` structure. This structure is furthermore relatively stable over the 15 year period for the lymphocytic leukaemias which make up the majority of observed cases. We found no evidence of a positive association of childhood leukaemia incidence with outdoor or indoor gamma radiation levels. There is no consistent evidence of any association with radon levels. Indeed, in the Poisson regressions, a significant positive association was only observed for one 5-year period, a result which is not compatible with a stable environmental effect. Moreover, this positive association became clearly non-significant when over-dispersion relative to the Poisson distribution was taken into account. (author).

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

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

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

    Full Text Available BACKGROUND: 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.

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

    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

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

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

    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

Apenas dois estudos verificaram redução na incidência de pneumonia associada à ventilação mecânica com o uso do sistema fechado, e um destes revelou um risco 3.5 vezes maior de desenvolvimento desta infecção com o sistema aberto. Os resultados sugerem que o impacto do sistema de aspiração traqueal aberto e fechado é semelhante para o desenvolvimento da pneumonia associada à ventilação mecânica, assim a escolha do tipo de sistema de aspiração traqueal deve ser baseada em outros parâmetros.

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

    Full Text Available Abstract Background 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

We aimed to investigate the incidence of hepatotoxicity and the role of concomitant use of fluconazole in HIV-infected patients receiving TMP/SMX for Pneumocystis jirovecii pneumonia. We reviewed medical records to collect clinical characteristics and laboratory data of HIV-infected patients who received TMP/SMX for treatment of P. jirovecii pneumonia at 6 hospitals around Taiwan between September 2009 and February 2013. Hepatotoxicity was defined as 2-fold or greater increase of aminotransferase or total bilirubin level from baselines.

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

    Full Text Available ABSTRACT : PURPOSE: To compare the VAP incidence in various (ICUs and analyze the trend of the microbial pathogens and their antimicrobial susceptibilit y pattern. METHOD: The prospective observational study with a surveillance module consisting of a ventilator bundle checklist and modified CPI score card was created for each patient on ventilator. The pathogens isolated by quantitative culture of the endotr acheal aspirate (ETA from suspected VAP cases were identified and the antimicrobial susceptibility was determined by Vitek 2 compact. RESULT: There was a decline in the overall incidence of VAP from 3.11 in 2011 to1.73 in 2012. A similar trend was seen in t he medical ICUs , from 4.16 to 1.07in MICU , 2.48 to 0 in LICU. A decline in the incidence in surgical ICUs , from 7.38 to 2.64 in CTVS , 7.55 to 2.41 in STICU was observed. Pseudomonas spp , Acinetobacterspp , ESBL producing Klebsieillapneumoniae were the most common pathogens causing late - onset VAP. The resistance to colistin has increased from 0 to 25% , ceftazidime from 36 to 95%in Pseudomonas spp.In case of Acinetobacterspp , susceptibility to colistin remained 100% but tegicycline resistance increased from 12 to 50%. For ESBL producing Klebsiellapneumoniae resistance to amikacin increased from 14 to 67% , imipenem and meropenem had no resistance. CONCLUSION: A high clinical suspi cion of pneumonia with prompt correlation with microbiological culture findings and radiological studies helps to identify VAP cases and reduce the incidence of VAP. Aggressive surveillance of the microbial pathogens with their antimicrobial susceptibility pattern gives an insight of the local Microbiologic milieu of a given unit , thereby helps us to arrive at an empirical usage of antibiotics. Antimicrobial resistant pattern has to be closely watched and corrective measures like rotation of or change of em pirical antibiotics will help in overcoming resistance

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

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

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

    Acyl-CoA dehydrogenase family, member 9 (ACAD9) mutation is a frequent, usually fatal cause of early-onset cardiac hypertrophy and mitochondrial respiratory chain complex I deficiency in early childhood. We retrospectively studied a series of 20 unrelated children with cardiac hypertrophy and isolated complex I deficiency and identified compound heterozygosity for missense, splice site or frame shift ACAD9 variants in 8/20 patients (40%). Age at onset ranged from neonatal period to 9 years and 5/8 died in infancy. Heart transplantation was possible in 3/8. Two of them survived and one additional patient improved spontaneously. Importantly, the surviving patients later developed delayed-onset neurologic or muscular symptoms, namely cognitive impairment, seizures, muscle weakness and exercise intolerance. Other organ involvement included proximal tubulopathy, renal failure, secondary ovarian failure and optic atrophy. We conclude that ACAD9 mutation is the most frequent cause of cardiac hypertrophy and isolated complex I deficiency. Heart transplantation in children surviving neonatal period should be considered with caution, as delayed-onset muscle and brain involvement of various severity may occur, even if absent prior to transplantation.

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

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

    Full Text Available 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.

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

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

    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.

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

  9. A compendium for Mycoplasma pneumoniae

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

    1996-06-01

    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.

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

    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 OBJETIVO: Analisar a incidência de pneumonia necrosante (PN em crianças submetidas a toracoscopia e comparar pacientes com e sem PN em relação às diferentes apresentações e evolução clínica. MÉTODOS: Estudo retrospectivo de crianças portadoras de empiema e submetidas a toracoscopia. A toracoscopia foi realizada em pacientes não submetidos a drenagem torácica prévia e evidência de derrame septado ou pneumotórax, assim como naqueles submetidos previamente a drenagem torácica e pneumotórax persistente ou febre e secreção purulenta. Baseado na presença de PN durante a toracoscopia, os pacientes foram divididos em dois grupos: com PN e sem PN. RESULTADOS: Participaram do estudo 52 pacientes. Dos 24 pacientes com PN, 19 (79% foram submetidos a drenagem torácica anterior à toracoscopia, 11 (46% apresentaram pneumotórax, e 16 (67% evoluíram com fístula broncopleural. Neste grupo, as medianas do tempo de drenagem e de hospitalização foram, respectivamente, 18 e 19 dias. Dos 28 pacientes sem PN, 10 (36% foram submetidos a drenagem torácica anterior à toracoscopia, 9 (32% apresentaram pneumotórax, e 5 (18% evoluíram com fístula broncopleural. Neste grupo, as medianas do tempo médio de drenagem e de hospitalização foram, respectivamente, 6 e 10 dias. CONCLUSÕES: A PN deve ser suspeitada na presença de pneumotórax. A toracoscopia precoce pode ser uma opção terapêutica de grande valor na PN da infância, pois acelera a recuperação quando comparada ao tratamento médico isolado e evita ressecções pulmonares extensas da toracotomia tardia.OBJECTIVE: To assess the incidence of necrotizing pneumonia (NP in children submitted to thoracoscopy, comparing patients with and without NP in terms of the presentation and clinical evolution.

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

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

The aim of this study was to assess the annual incidence of osteomyelitis in children, describe the patient and disease characteristics in those with acute ( Methods In a population-based Norwegian study physicians were asked to refer all children with suspected osteomyelitis. Children with osteomyelitis received follow-up at six weeks, six months and thereafter as long as clinically needed. Results The total annual incidence rate of osteomyelitis was 13 per 100 000 (acute osteomyelitis 8 and subacute osteomyelitis 5 per 100 000. The incidence was higher in patients under the age of 3 than in older children (OR 2.9, 95%: CI 2.3–3.7. The incidence of non-vertebral osteomyelitis was higher than the incidence of vertebral osteomyelitis (10 vs. 3 per 100 000; p = .002. Vertebral osteomyelitis was more frequent in girls than in boys (OR 7.0, 95%: CI 3.3–14.7. ESR ≥ 40 mm/hr had the highest positive predictive laboratory value to identify osteomyelitis patients at 26% and MRI had a positive predictive value of 85%. Long-bone infection was found in 16 (43% patients. ESR, CRP, white blood cell count, neutrophils and platelet count were higher for patients with acute osteomyelitis than for patients with subacute osteomyelitis. Subacute findings on MRI and doctor's delay were more common in subacute osteomyelitis than in acute osteomyelitis patients. Blood culture was positive in 26% of the acute osteomyelitis patients and was negative in all the subacute osteomyelitis patients. Conclusion The annual incidence of osteomyelitis in Norway remains high. ESR values and MRI scan may help to identify osteomyelitis patients and differentiate acute and subacute osteomyelitis.

    2014-01-01

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

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

  19. Analysis of the Relation Between Exposure to Ionising Radiation from Computed Tomography Scans in Childhood and Cancer Incidence within the 'Cohorte Enfant Scanner' Study

    International Nuclear Information System (INIS)

    Computed tomography (CT) is a powerful imaging technique that provides great benefits for diagnosis and medical management of patients. Nonetheless, the widespread use of this procedure raises many concerns about the potential adverse effects induced by X-rays exposure, both in clinical practice and in terms of public health. First epidemiological studies have suggested an increased risk of cancer associated with CT scan exposures in childhood or adolescence. The interpretation of these results is, however, controversial, and evidence about radiation-induced risks of cancer is still limited at this level of exposure and during childhood. In France, the 'Enfant Scanner' cohort was set up by IRSN to study the incidence of cancer among more than 100,000 children who received CT scans before the age of 10 in 21 university hospitals. This study is part of the European Epi-CT project - coordinated by the International Agency for Research on Cancer - which includes nine national cohorts set up on the basis of a common protocol. The current thesis, based on the French cohort, focuses on characterizing the exposure of children receiving diagnostic CT scans and quantifying the risk of cancer associated with these exposures. Dosimetric assessment was performed from the radiological protocols used in paediatrics between 2000 and 2011 in the participating hospitals. This study presents the evolution of the exposures during the period and the variability of practices in the radiology departments. The results show that there is a leeway for optimizing the procedures and limiting the exposure of patients, especially for scans of the head that account for most of the examinations in paediatrics. A quantitative assessment of cancer risk potentially induced by CT scans in paediatrics was performed - on the basis of estimates of risk in other contexts of ionizing radiation exposure. The results show that each CT scan could be associated with an excess risk of tumours of the

  20. AS03 adjuvanted AH1N1 vaccine associated with an abrupt increase in the incidence of childhood narcolepsy in Finland.

    Hanna Nohynek

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

    OBJECTIVE To evaluate the effect of a multidimensional infection control bundle on the incidence of ventilator-associated pneumonia (VAP) in 176 intensive care units (ICUs) in Shanghai. METHODS The trial was designed as a before-after study in 176 ICUs of 67 two-A and three-A hospitals in Shanghai from Jan 2007 to Jun 2012, which was divided into the baseline, transition and intervention periods. The interventions of the VAP group included the hand hygiene, recumbent bed position, and oral care with antiseptic, as well as education and supervision for the medical personnel. The number of the discharged cases, general information, length of ICU stay, duration of mechanical ventilation, and the incidence of VAP were collected by the infection control personnel. The incidence of VAP was compared before and after the interventions, and the effects of the bundle were e-valuated. RESULTS Of totally 463 208 patients whose clinical data were collected in this study, there were 2 535 917 days of ICU stay were monitored and 695 185 days (VDs) The incidence of VAP during the baseline investigation period was 23. 4 per 1000 VDs and was significantly decreased after the implementation of the bundle interventions, the incidence of VAP during 2009-2012 was 14. 3 per 1000 VDs, RR = 0. 61 (95%CI, 0. 59~0. 64), RD = 9. 1(95%CI, 8. 3 ~ 9. 9).

    2012-04-01

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

    Full Text Available Abstract Background 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.

  9. Chest x-ray quality in the diagnosis of pneumonia in children: From prescription to optimization

    International Nuclear Information System (INIS)

    Acute lower respiratory tract infection (ALRI), primarily pneumonia, is the leading cause of childhood death in developing countries. The increasing incidence of antimicrobial resistance and the high cost of vaccines lead to considering the first strategy to reduce pneumonia deaths the early detection of the disease. Case management begins with the clinical examination and may continue with the prescription of a chest x-ray. Consequently, the radiograph should meet quality standards, and radiologists and paediatricians must know how to interpret the images. Special attention should be paid on patient dose due to children radiosensitivity, high frequency and chest x rays rejection rate. This paper is a retrospective study of chest radiographs performed in 5731 children with clinical diagnosis of ALRI assisted in three Uruguayan hospitals during the three year investigation supported by the Division of Vaccines and Immunization of the Pan American Health Organization (PAHO) that had the aim of estimating the burden of pneumonia (from 2001 to 2004). It is analyzed the prescription of radiographs during the diagnosis and in later controls (2220 children assisted in two of the three hospitals). Patient doses are estimated from technical parameters and equipment specifications. The investigation also analyzes patient doses that could have been avoided if paediatricians had managed the disease according to the established protocols. Results show that 82.4 % of chest x-rays diagnosed pneumonia and that some children underwent up to ten radiographs. Significant differences were found in patient dose in the three hospitals, concluding that education on image quality on chest radiographs of radiologists, paediatricians and radiological technologists is the first and best tool for the earlier diagnosis of pneumonia in children and for the application of Radiation Protection (RP) principles in medical exposures.

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

    Pneumonia infection is a significant cause of morbidity and mortality worldwide. In addition to the public health concerns, pneumonia also accounts for a significant cost to the health care system. Currently there are two leading vaccines targeted against S. pneumoniae: 23-valent pneumococcal polysaccharide vaccine (PPSV23) and 13-valent pneumococcal conjugate vaccine (PCV13). Until recently the recommendation for adult pneumonia vaccination has been a single dose of PPSV23 for all adults 65 years and older. However, concerns were raised regarding the vaccine’s efficacy due to the persistent burden of pneumococcal disease in the elderly population. This paper focuses on two trials which evaluate the safety and efficacy of PCV13 in the adult population. The first study reveals improved immune response with the addition of PCV13 to PPSV23, while the second shows PCV13 was effective in the prevention of vaccine-type community-acquired pneumonia. The two studies observed adequate safety profiles for PCV13 in series with PPSV23 and with PCV13 compared to placebo. PMID:27376105

    2006-04-01

    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.

    Full Text Available Hand, foot and mouth disease (HFMD has been a substantial burden throughout the Asia-Pacific countries over the past decades. For the purposes of disease prevention and climate change health impact assessment, it is important to understand the temperature–disease association for HFMD in different geographical locations. This study aims to assess the impact of temperature on HFMD incidence in an inland city and a coastal city and investigate the heterogeneity of temperature–disease associations. Daily morbidity data and meteorological variables of the study areas were collected for the period from 2007 to 2012. A total of 108,377 HFMD cases were included in this study. A distributed lag non-linear model (DLNM with Poisson distribution was used to examine the nonlinear lagged effects of daily mean temperature on HFMD incidence. After controlling potential confounders, temperature showed significant association with HFMD incidence and the two cities demonstrated different impact modes ( I2= 96.1%; p < 0.01. The results highlight the effect of temperature on HFMD incidence and the impact pattern may be modified by geographical localities. Our findings can be a practical reference for the early warning and intervention strategies of HFMD.

    2016-01-01

    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

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

    To study the complete natural process of a Mycoplasma pneumoniae outbreak in a semiclosed room such as a primary school room, we investigated two separate M. pneumoniae outbreaks involving 81 students in total in two primary schools in Hangzhou, China. M. pneumoniae isolates from pharyngeal swabs were detected by fluorescence quantitative real-time PCR (RT-PCR) and culture. The class in school M had 39 students, with 12 (30.8%) with positive M. pneumoniae detection results. The class from school J had 42 students, with 13 (31.0%) positive. The strains from two classes were confirmed to represent two clones (3/4/5/7/2 and 5/4/5/7/2) and to be macrolide resistant (A2063G) according to P1 and multilocus variable-number tandem-repeat analysis (MLVA) genotyping, determination of MIC of antibiotics, and sequencing. Students with M. pneumoniae isolates detected were divided into three groups: those carrying the isolates, those with upper respiratory tract infection (URI), and those with pneumonia. Longitudinal sampling performed using pharyngeal swabs showed that the persistence of M. pneumoniae was longest in the group of students with pneumonia. M. pneumoniae causes pneumonia outbreaks in schools, and the incidence of pneumonia has a higher rate than that of URI. The persistence of M. pneumoniae, with a median duration of 79.50 days in the group of students with pneumonia, differs from that of the infection state. PMID:27161643

    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 Childhood vitiligo differs from the adults by showing a higher incidence in females, segmental vitiligo being more common and less frequent association with other systemic autoimmune and endocrine disorders.Childhood vitiligo is often associated with a marked psychosocial and long lasting effect on the self-esteem of the affected children and their parents, hence an adequate treatment is very essential. Treatment of vitiligo is indeed a tough challenge for the dermatologists′ more so in the background of childhood vitiligo. Although multiple therapeutic modalities are available in the therapeutic armamentarium, not all can be used in children. This brief report updates regarding various therapies available in the treatment of childhood vitiligo.

    More than three-quarters of deaths related to major burns are a consequence of infection, which is frequently ventilator associated pneumonia (VAP). A retrospective study was performed, over a five-year period, of ventilated children with major burns. 92 patients were included in the study; their mean age was 3.5 years and their mean total body surface area burn was 30%. 62% of the patients sustained flame burns, and 31% scalds. The mean ICU stay was 10.6 days (range 2-61 days) and the mean ventilation time was 8.4 days (range 2-45 days). There were 59 documented episodes of pneumonia in 52 patients with a rate of 30 infections per 1000 ventilator days. Length of ventilation and the presence of inhalational injury correlate with the incidence of VAP. 17.4% of the patients died (n=16); half of these deaths may be attributed directly to pneumonia. Streptococcus pneumonia, Pseudomonas aeruginosa, Acinetobacter baumanii and Staphylococcus aureus were the most prominent aetiological organisms. Broncho-alveolar lavage was found to be more specific and sensitive at identifying the organism than other methods. This study highlights the importance of implementing strictly enforced strategies for the prevention, detection and management of pneumonia in the presence of major burns. PMID:24468505

    2008-06-01

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

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

  13. Computed tomographic study on Mycoplasma pneumoniae pneumonia

    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.

    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

    Migraine is one of the most frequently reported somatic complaints in childhood, with a negative impact on health-related quality of life. The incidence of migraine in childhood has substantially increased over the past 30 years, probably due to both increased awareness of the disease and lifestyle changes in this age group. Indeed, several conditions have been identified as risk factors for migraine in childhood. Amongst these, dysfunctional family situation, the regular consumption of alcohol, caffeine ingestion, low level of physical activity, physical or emotional abuse, bullying by peers, unfair treatment in school and insufficient leisure time seem to play a critical role. Nevertheless, there are only few studies about the association between migraine and lifestyle in childhood, due to previous observations specifically focused on "headache" in children. In this brief review, we will concentrate upon recent studies aimed to explore migraine and lifestyle risk factors in childhood. PMID:26017522

    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

  15. 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.

    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.

  2. Clinical and radiological diagnosis of chronic pneumonia in pneumoconiosis and dust bronchitis

    International Nuclear Information System (INIS)

    Clinical and radiologic symptomatology of chronic pneumonia is described for pneumoconiosis and chronic dust bronchitis. Combined X-ray methods of examination permit the physicians to discover this complication in dust diseases of the lungs in the presence of diffuse pneumosclerotic changes in 76.5+-3 % of cases. These data approach the values of chronic pneumonia incidence among the population. Chronic pneumonia diagnosis should be complex. If no less than 2 to 3 X-ray signs of the disease have been found simultaneously, the significance of radiologic diagnosis of chronic pneumonia in dust pathology of the lungs, rises. Radiologic examination, supported by clinical, anamnestic and laboratory data, allows one to differentiate chronic pneumonia from coniotuberculosis. Chest X-rays in dust pathology of the lungs, complicated by chronic pneumonia, should be carried out with regard to clinical indications

  4. Exogenous lipid pneumonia

    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

    Hadda, Vijay; Khilnani, Gopi C

    2010-12-01

    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

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

    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.)

  11. Rainfall is a risk factor for sporadic cases of Legionella pneumophila pneumonia.

    Directory of Open Access Journals (Sweden)

    Carolina Garcia-Vidal

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

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

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

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.

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

    Marrie, T J

    2003-04-01

    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

    2004-01-01

    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.

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

  4. Feedlot Acute Interstitial Pneumonia.

    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.

    Pneumonia due to methicillin-resistant Staphylococcus aureus (MRSA) is associated with poor outcomes and frequently merits empirical antibiotic consideration despite its relatively low incidence. Nasal colonization with MRSA is associated with clinical MRSA infection and can be reliably detected using the nasal swab PCR assay. In this study, we evaluated the performance of the nasal swab MRSA PCR in predicting MRSA pneumonia. A retrospective cohort study was performed in a tertiary care cente...

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

    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

  8. Pulmonary function abnormalities in long-term survivors of childhood cancer

    International Nuclear Information System (INIS)

    Pulmonary function testing (PFT) was performed on 29 long-term survivors of childhood cancer. The patients, whose mean age was 11.7 years and whose mean age at diagnosis was 3.7 years, included 12 females and 17 males. Original diagnoses included 15 patients with leukemia and 14 individuals with solid tumors. Nine patients had received cyclophosphamide and 20 had received radiation therapy. Included in this latter group were five patients who had received radiation therapy to the thorax. Eight patients had acquired pneumonia during their treatment. Physical examination was normal in all the patients, and none had a history of acute or chronic pulmonary disease. PFT demonstrated an incidence of abnormalities in forced vital capacity (FVC) and/or total lung capacity (TLC) in 48% of the patients. Patients who were under 3 years of age at the time of diagnosis or who had received radiation to the thorax were more likely to demonstrate PFT abnormalities, but these differences did not reach statistical significance. The natural history of pulmonary function and subsequent respiratory disease in survivors of childhood cancer requires further definition

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

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

    Mycoplasma pneumoniae is increasingly recognized as a common and important pathogen in community settings, and is responsible for various pulmonary and extrapulmonary conditions in the normal population. However, the seroepidemiology of acute M. pneumoniae infection in HIV-infected individuals is still unclear worldwide. This study examined the seroprevalence of antibodies to M. pneumoniae in HIV-infected patients admitted with respiratory complaints at a tertiary AIDS care centre in Chennai, India. A commercial gelatin microparticle agglutination test (Serodia-Myco II, Fujirebio) was used for the determination of antibodies against M. pneumoniae in acute serum specimens. Of the 200 HIV-infected patients with underlying pulmonary conditions tested, 34 (17 % positivity; 95 % CI 12-23 %) had antibodies specific to M. pneumoniae, while among the 40 patients with no underlying pulmonary symptoms, five (12.5 % positivity; 95 % CI 4-27 %) had evidence of anti-M. pneumoniae antibody. This shows that the incidence of M. pneumoniae seropositivity is greater in patients with underlying pulmonary complaints. Most positive titres were found in the age group 28-37 years in the symptomatic and symptom-free groups (64.7 and 60 %, respectively). The positive titres ranged from 40 to >20 480. High titres (> or =320) were found in 10 out of the 39 patients (25.6 %). This seroprevalence study reports a 16.2 % prevalence of M. pneumoniae infections in HIV-infected patients by a particle agglutination test.

    Full Text Available A duplex real-time PCR assay was designed for simultaneous detection and genotyping of Mycoplasma pneumoniae (M. pneumoniae. The detection/typing performance of this duplex PCR method, targeting specific genes for M. pneumoniae type 1 (mpn 459 and type 2 (mpna 5864, was compared to that of the previously published MpP1 real-time PCR assay and the genotyping method for the adhesin P1 gene (mpn 141. A total of 1,344 throat swab specimens collected from patients in Beijing, China were tested for M. pneumoniae by bacterial culture, MpP1 real-time PCR assay, and our duplex PCR assay, and positive detection rates of 26.9%, 34.4%, and 33.7%, respectively, were obtained. The duplex PCR method demonstrated high sensitivity and accuracy for detecting and genotyping M. pneumoniae, and significant differences in genotyping ability were observed when compared to the conventional P1 gene-based method. M. pneumoniae type 1 was the predominate genotype from 2008 to 2012 in Beijing, and a shift from type 1 to type 2 began to occur in 2013. To our knowledge, this is the first reported incidence of a type shift phenomenon of M. pneumoniae clinical isolates in China. These genotyping results provide important information for understanding recent changes in epidemiological characteristics of M. pneumoniae in Beijing.

  16. 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

    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.

    2010-01-01

    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 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.

    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.

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.

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

    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 Strepto...

    Brazil introduced the 10-valent pneumococcal non-typeable Haemophilus influenzae protein D conjugate vaccine (PHiD-CV, Synflorix™, GSK Vaccines) in the routine childhood immunization program in 2010 with a 3+1 schedule (with catch-up for children pneumococcal conjugate vaccine on nasopharyngeal carriage and all the major pneumococcal disease manifestations in a single, pneumococcal conjugate vaccine-naïve, developing 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

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

    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.

    Full Text Available Childhood vitiligo is often encountered in dermatological practice. 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.

    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.

    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.

  19. Ventilator Circuits, Humidification and Ventilator-Associated Pneumonia

    Directory of Open Access Journals (Sweden)

    Dean Hess

    1996-01-01

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

  20. Radiologic and clinical findings of mycoplasma pneumonia in children

    International Nuclear Information System (INIS)

    Mycoplasma Pneumonia is a cause of primary atypical pneumonia, but it is asymptomatic mostly or may cause of only mild symptoms. School-aged children experienced high attack rate and manifestation if 'unusual pneumonia' are noted. So authors reviewed clinical and radiological features of 110 cases of serologically proven Mycoplasma pneumonia in hospitalized children between November 1984 and January 1987 retrospectively. The results were as follows ; 1. The sex distribution was 57:53 (1.1:1) in male to female ratio and 47% of them were 5 though 8 years old of age with peak incidence between 5 and 6 years old of age. 2. The symptoms were cough, fever, and sore throat in descending order of frequency and mean symptom duration before admission was 8.1 day. The prevalent season was earlier winter. 3. The radiologic findings were air-space consolidation with lobar, segmental distribution in 68%, interstitial infiltration in 12%, bronchopneumonia in 12%, chronic bronchitis pattern in 3.6%, normal in 4.5%, hilar LN enlargement in 37%, pleural effusion in 12%. 4. Radiologic resolution period was usually 10 days around (4-25 days) and after complete recovery, scarring change or calcification was not seen. 5. Extrapulmonary manifestations were uncommon but hepatitis, hematuria, skin rash, gastroenteritis, myocarditis, otitis media occurred. 6. With administration of tetracyclin and erythromycin, clinical and radiologic responses were promptly seen

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

    Directory of Open Access Journals (Sweden)

    Grossi Paolo

    2005-11-01

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

  5. 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

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

    Directory of Open Access Journals (Sweden)

    Robert F Breiman

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

    Pneumonia is a 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.

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

    Directory of Open Access Journals (Sweden)

    Evropi Theodoratou

    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.

    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

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

    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.

    2009-04-01

    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.

    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

    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

    2015-01-01

    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

    1999-11-01

    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.

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

    2014-05-06

    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

    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)

    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.

    2011-01-01

    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

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.

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

    Full Text Available Background : Mycoplasma pneumoniae is implicated in acute exacerbations of bronchial asthma and is also a factor in the chronicity of asthma. This study was conducted to determine the significance of this association and to estimate the incidence of M.pneumoniae in the airways of asthmatics by isolation of the organism in sputum by culture method. Methods: In our study we have tried to isolate M.pneumoniae in sputum specimen samples by culture technique in one hundred asthmatic patients and fifty non-asthmatics who served as controls. Results : In our study we were able to isolate M.pneumoniae by sputum culture in 18% of the asthmatics. Among the culture positive patients, 16% had acute exacerbation of asthma. Conclusions : Our study compares favorably with the earlier studies done using serology and PCR in the diagnosis of M.pneumoniae infections in asthma emphasizing the usefulness of sputum cluture as a reliable investigative tool for isolation of M.pneumoniae in asthmatics. It also suggests a role for broader therapeutic implications in treatment of asthma. Lung India 2005; 22 : 50-53

    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.

  11. Community epidemiology of Chlamydia and Mycoplasma pneumoniae in LRTI in France over 29 months

    International Nuclear Information System (INIS)

    Background: The role of Chlamydia pneumoniae (CP) and Mycoplasma pneumoniae (MP) in lower respiratory tract infections (LRTI) is still little known in community settings. Methods: In all, 3207 adult cases of LRTI (871 with pneumonia, and 2336 with acute bronchitis) were prospectively included in the ETIIC1ETIIC : ETude de l'Incidence des Infections respiratoires basses d'origine Communautaire dues a Chlamydia pneumoniae et Mycoplasma pneumoniae (Incidence of CP and MP in LRTI in community settings)program by 303 general practitioners and 24 hospital physicians in France between September 1997 and February 2000. The polymerase chain reaction and immunoassays were used to detect CP or MP in 3198 pharyngeal specimens obtained by gargling. Results: Of these 3198 patients, 232 (7.3%), were PCR-positive for CP and/or MP. Immunoassays were far less sensitive than PCRs (Se = 2 and 13% for MP and CP). Among the 2336 patients with acute bronchitis, PCR was positive for CP in 95 (4.1%), and for MP, in 54 (2.3%). Among the 671 patients with radiologically confirmed pneumonia, PCR was positive for CP in 23 (3.4%), and for MP in 49 (7.3%). CP and MP displayed significant geographic heterogeneity. Independent clinical determinants of positive PCR for CP and/or MP were age below 45 years, previous antimicrobial therapy (especially betalactams). Clinical signs were not of practical use in distinguishing accurately between etiologic diagnoses. Conclusions: CP or MP diagnosed by PCR were found in more than 7% of patients with LRTI in community settings with a significant geographical heterogeneity and significant temporal trends in the incidence

    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

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

    Directory of Open Access Journals (Sweden)

    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.

    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.

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

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

    Directory of Open Access Journals (Sweden)

    Ya-Tang Liao

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

  20. The spread of Mycoplasma pneumoniae is polyclonal in both an endemic setting in France and in an epidemic setting in Israel.

    Directory of Open Access Journals (Sweden)

    Sabine Pereyre

    Full Text Available Mycoplasma pneumoniae infections occur both endemically and epidemically, and macrolide resistance has been spreading for 10 years worldwide. A substantial increased incidence of M. pneumoniae infections has been reported in several countries since 2010. Whether this increased incidence is attributed to different or to the same M. pneumoniae genotype is unknown. We have developed a multilocus variable-number tandem-repeat (VNTR analysis (MLVA for the molecular typing of M. pneumoniae isolates. In this study, the MLVA typing method was modified and validated to be applicable directly to respiratory tract specimens without culture. This method was applied to 34 M. pneumoniae-positive specimens received at the Bordeaux Hospital, France, between 2007 and 2010 in an endemic setting, and to 63 M. pneumoniae-positive specimens collected during an epidemic surge of M. pneumoniae infections in 2010 in Jerusalem, Israel. The M. pneumoniae endemic spread was shown to be polyclonal in France, with 15 MLVA types identified. Strikingly, the Israeli epidemic surge was also a multi-clonal phenomenon, with 18 circulating MLVA types. The macrolide resistance-associated substitution, A2058G, was found in 22% of the Israeli patients. Macrolide-resistant M. pneumoniae belonged to four MLVA types, the MLVA type Z being the most frequent one. An association between the MLVA type Z and macrolide resistance might exist since macrolide resistance was present or generated during the course of illness in all patients infected with this MLVA type. In conclusion, the discriminatory power of the MLVA showed that the spread of M. pneumoniae strains in France in an endemic setting was polyclonal as well as the surge of M. pneumoniae infections in Israel in 2010.

    2015-07-01

    A 4-month-old boy with past medical history of eczema presented with fever and cough; a chest radiograph showed lung consolidation, and he was initially treated with amoxicillin for presumed community-acquired pneumonia. After several days, his fever persisted. He was also profoundly anemic. Antibiotic coverage was broadened because of the concern for resistant organisms; he began to improve and was discharged from the hospital. However, at 5 months of age, his fever returned, and he continued to demonstrate lung consolidation on chest radiograph. Additionally, he had lost weight and continued to be anemic. Splenic cysts were noted on abdominal ultrasound. He was diagnosed with an unusual etiology for his pneumonia and improved with the appropriate therapy. An underlying immunodeficiency was suspected, but initial testing was nondiagnostic. At 12 months of age, he presented with another infection, and the final diagnosis was made. PMID:26122810

  3. 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.)

    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)

    Full Text Available BACKGROUND: PCV7 was introduced as universal childhood vaccination in Israel in July 2009 and PCV13 in November 2010. Here we report data on adult invasive pneumococcal disease (IPD, two years post PCV7 implementation and before an expected effect of PCV13. METHODS: An ongoing nationwide active-surveillance (all 27 laboratories performing blood cultures in Israel, providing all blood & CSF S. pneumoniae isolates from persons >18 y was initiated in July 2009. Capture-recapture method assured reporting of >95% cases. All isolates were serotyped in one central laboratory. IPD outcome and medical history were recorded in 90%. Second year post PCV implementation is compared to the first year. RESULTS: During July 2009 to June 2011, 970 IPD cases were reported (annual incidence [/100,000] of 9.17 and 10.16 in the two consecutive years, respectively. Respective case fatality rates (CFRs were 20% and 19.1%. Incidence of IPD and CFR increased with age and number of comorbidities. Incidence rate was significantly greater during the second winter, 7.79/100,000 vs. 6.14/100,000 in first winter, p = 0.004, with a non-significant decrease during summer months (3.02 to 2.48/100,000. The proportion of IPD cases due to PCV7-serotypes decreased from 27.5% to 13.1% (first to second year (p64 y. Among younger/healthier patients serotype 5 was the major increasing serotype. Penicillin and ceftriaxone resistance decreased significantly in the second year. CONCLUSIONS: While overall annual incidence of IPD did not change, the indirect effect of PCV7 vaccination was evident by the significant decrease in PCV7 serotypes across all age groups. Increase in non-VT13 strains was significant in immunocompromised patients. A longer follow-up is required to appreciate the full effect of infant vaccination on annual IPD.

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

  12. Chronic Disease at Midlife: Do Parent-child Bonds Modify the Effect of Childhood SES?

    Andersson, Matthew A

    2016-09-01

    Childhood socioeconomic status (SES) often is associated with physical health even decades later. However, parent-child emotional bonds during childhood may modify the importance of childhood SES to emergent health inequalities across the life course. Drawing on national data on middle-aged adults (1995 and 2005 National Survey of Midlife Development in the United States; MIDUS; Ns = 2,746 and 1,632), I find that compromised parent-child bonds eliminate the association between childhood SES and midlife disease. Longitudinal models of incident disease across one decade show that childhood abuse in particular continues to undermine the health protection associated with childhood SES. When childhood SES is moderate to high, compromised parent-child bonds lead to no predicted health benefits from childhood SES. In total, these findings direct attention to parent-child bonds as social-psychological levers for the transmission of class-based health advantages. PMID:27601411

    Full Text Available Despite the considerable number of studies reported to date, the causative agents of pneumonia are not completely identified. 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.

  1. Organizing pneumonia after stereotactic ablative radiotherapy of the lung

    International Nuclear Information System (INIS)

    Organizing pneumonia (OP), so called bronchiolitis obliterans organizing pneumonia after postoperative irradiation for breast cancer has been often reported. There is little information about OP after other radiation modalities. This cohort study investigated the clinical features and risk factors of OP after stereotactic ablative radiotherapy of the lung (SABR). Patients undergoing SABR between 2004 and 2010 in two institutions were investigated. Blood test and chest computed tomography were performed at intervals of 1 to 3 months after SABR. The criteria for diagnosing OP were: 1) mixture of patchy and ground-glass opacity, 2) general and/or respiratory symptoms lasting for at least 2 weeks, 3) radiographic lesion in the lung volume receiving < 0.5 Gy, and 4) no evidence of a specific cause. Among 189 patients (164 with stage I lung cancer and 25 with single lung metastasis) analyzed, nine developed OP. The incidence at 2 years was 5.2% (95% confidence interval; 2.6-9.3%). Dyspnea were observed in all patients. Four had fever. These symptoms and pulmonary infiltration rapidly improved after corticosteroid therapy. Eight patients had presented with symptomatic radiation pneumonitis (RP) around the tumor 2 to 7 months before OP. The prior RP history was strongly associated with OP (hazard ratio 61.7; p = 0.0028) in multivariate analysis. This is the first report on OP after SABR. The incidence appeared to be relatively high. The symptoms were sometimes severe, but corticosteroid therapy was effective. When patients after SABR present with unusual pneumonia, OP should be considered as a differential diagnosis, especially in patients with prior symptomatic RP

    2014-12-01

    A growing number of studies in life course epidemiology and biodemography make use of a retrospective question tapping self-rated childhood health to assess overall physical health status. Analyzing repeated measures of self-rated childhood health from the Health and Retirement Study (HRS), this study examines several possible explanations for why respondents might change their ratings of childhood health. Results reveal that nearly one-half of the sample revised their rating of childhood health during the 10-year observation period. Whites and relatively advantaged older adults-those with more socioeconomic resources and better memory-were less likely to revise their rating of childhood health, while those who experienced multiple childhood health problems were more likely to revise their childhood health rating, either positively or negatively. Changes in current self-rated health and several incident physical health problems were also related to the revision of one's rating of childhood health, while the development of psychological disorders was associated with more negative revised ratings. We then illustrate the impact that these changes may have on an adult outcomes: namely, depressive symptoms. Whereas adult ratings of childhood health are likely to change over time, we recommend their use only if adjusting for factors associated with these changes, such as memory, psychological disorder, adult self-rated health, and socioeconomic resources.

  5. Childhood asthma and risk factors

    2010-01-01

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

  7. 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

  10. 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.

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

    This study aimed to collate data on childhood drowning in Malaysia and review existing drowning prevention measures. This study used secondary data from governmental and non-governmental agencies. All reported fatal drownings from 2000 to 2007 and all reported non-fatal drownings from 2000 to 2008 were included. Data were analysed to provide understanding of the epidemiology of drowning incidents, risk factors and available preventive efforts. On average 286 (range 248-344) children died yearly due to drowning with a death rate of 3.05 per 100,000 annually. An additional average of 207 children drowned but survived annually (1.99 per 100,000). The estimated burden of drowning in children (death and non-death) is 5 per 100,000. There was no reduction in annual drowning fatalities over time. Most drowning took place in east coast regions during the annual monsoon season. It was 3.52 (2.80-4.41) times more common in boys and most prevalent among 10-14 years. Most prevalent sites of all-age drowning were seas and rivers. Limited water safety regulations are currently available in the country. This is the first comprehensive national study in Malaysia on paediatric drowning and highlights the magnitude of the problem. It calls for concerted effort to devise effective national drowning prevention measures. PMID:23651461

    Full Text Available Abstract Background Streptococcus pneumoniae is the main pathogen that causes respiratory infections in children younger than five years. The increasing incidence of macrolide- and tetracycline-resistant pneumococci among children has been a serious problem in China for many years. The molecular characteristics of erythromycin-resistant pneumococcal isolates that were collected from pediatric patients younger than five years in Beijing in 2010 were analyzed in this study. Results A total of 140 pneumococcal isolates were collected. The resistance rates of all isolates to erythromycin and tetracycline were 96.4% and 79.3%, respectively. Of the 135 erythromycin-resistant pneumococci, 91.1% were non-susceptible to tetracycline. In addition, 30.4% of the erythromycin-resistant isolates expressed both the ermB and mef genes, whereas 69.6% expressed the ermB gene but not the mef gene. Up to 98.5% of the resistant isolates exhibited the cMLSB phenotype, and Tn6002 was the most common transposon present in approximately 56.3% of the resistant isolates, followed by Tn2010, with a proportion of 28.9%. The dominant sequence types (STs in all erythromycin-resistant S. pneumoniae were ST271 (11.9%, ST81 (8.9%, ST876 (8.9%, and ST320 (6.7%, whereas the prevailing serotypes were 19F (19.3%, 23F (9.6%, 14 (9.6%, 15 (8.9%, and 6A (7.4%. The 7-valent pneumococcal conjugate vaccine (PCV7 and 13-valent pneumococcal conjugate vaccine (PCV13 coverage of the erythromycin-resistant pneumococci among the children younger than five years were 45.2% and 62.2%, respectively. ST320 and serotype 19A pneumococci were common in children aged 0 to 2 years. CC271 was the most frequent clonal complex (CC, which accounts for 24.4% of all erythromycin-resistant isolates.

    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.

  17. Development of a new trend conjugate vaccine for the prevention of Klebsiella pneumoniae

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

    Full Text Available Objective: There are few therapeutic options for treatment of multidrug resistant Klebsiella pneumoniae isolates as a hospital infectious agent (nosocomial infection. The aim of this study was to evaluate the antibacterial activity of Zataria multiflora Boiss extracts against ESBL-producing Klebsiella pneumoniae strains. Materials and Methods: This study was conducted on 100 K. pneumoniae isolates from two hospitals in Tehran, Iran. Antibiotic susceptibility tests were performed by Kirby-Bauer disc diffusion and microdilution broth methods and detection of ESBL was carried out according to CLSI guidelines. The blaCTX-M-15plasmid genewas detected by PCR and sequencing methods. Extracts susceptibility test was performed by broth microdilution method.  Results: Among 100 K. pneumoniae strains, 48 (48% were ESBL positive. In this study, fosfomycin, colistin and tigecycline were more active than other antibiotics. The existence of blaCTX-M-15 was detected in 30 (62.5% of 48 ESBL-producing isolates. The chloroformic extract showed potent activity against ESBL-producing K. pneumoniae strains (MIC50 = 1.56 mg/ml and MIC90=3.12mg/ml. The MIC50 and MIC90 (The MIC50 represents the MIC value at which ≥50% of the isolates in a test population are inhibited and the MIC90 represents the MIC value at which ≥90% of the strains within a test population are inhibited were 3.12 and 6.25 mg/ml and 6.25  and 12.5 mg/ml for methanolic and acetonic extracts, respectively. Conclusions: The incidence of ESBL-producing K. pneumoniae is very high. Therefore, detection of ESBL-producing K. pneumoniae isolates is of great importance in identifying drug resistance patterns in K. pneumoniae isolates and in control of infections. Zataria multiflora may have the potential to be used against multidrug resistant organisms such as clinical isolates of ESBL-producing K. pneumoniae.

    Few studies have formally examined the relationship between meteorological factors and the incidence of child pneumonia in the tropics, despite the fact that most child pneumonia deaths occur there. We examined the association between four meteorological exposures (rainy days, sunshine, relative humidity, temperature) and the incidence of clinical pneumonia in young children in the Philippines using three time-series methods: correlation of seasonal patterns, distributed lag regression, and case-crossover. Lack of sunshine was most strongly associated with pneumonia in both lagged regression [overall relative risk over the following 60 days for a 1-h increase in sunshine per day was 0·67 (95% confidence interval (CI) 0·51-0·87)] and case-crossover analysis [odds ratio for a 1-h increase in mean daily sunshine 8-14 days earlier was 0·95 (95% CI 0·91-1·00)]. This association is well known in temperate settings but has not been noted previously in the tropics. Further research to assess causality is needed. PMID:22884022

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

    1986-06-01

    A retrospective analysis of treatment in 20 patients who had received post-operative radiotherapy for medulloblastoma between 1969 and 1977 was completed. The patients were followed for a minimum of 60 months. Eleven patients survived for 5 or more years after treatment. The patients received 3600 cGy to the whole brain. The posterior fossa received 5600 cGY and the spinal axis 3600 cGY. Eight of eleven patients developed growth impairment; 6 of 7 patients had growth hormone deficiency. Since all endocrine gland failures are amenable to therapy, early attention to patients' growth rate and detection of hypothalamic-pituitary failure, would be of benefit to longterm survivors.

  7. Correlations between computed tomography findings and clinical manifestations of Streptococcus pneumoniae pneumonia

    International Nuclear Information System (INIS)

    The aim of this study was to characterize the imaging features and compare computed tomography (CT) findings with clinical features of patients with Streptococcus pneumoniae pneumonia. We retrospectively reviewed 75 patients (44 men, 31 women; mean age 67 years) diagnosed with S. pneumoniae pneumonia who underwent chest CT scanning at our institution between January 2007 and August 2008. Diagnoses were based on detection of the S. pneumoniae antigen in urine. Chest CT scans revealed abnormalities in all patients. The predominant opacity patterns were an airspace pneumonia pattern (48%) and a bronchopneumonia pattern (48%), followed by an interstitial pneumonia pattern (4%). Consolidation was observed most frequently (84%) followed by ground glass opacity (82.7%), bronchial wall thickening (61.3%), and centrilobular nodules (49.3%). Airway dilatation (21.6%), pleural effusion (33.3%), lymphadenopathy (34.8%), and pulmonary emphysema (21.3%) were also observed. Pulmonary emphysema was significantly less frequent in patients with the bronchopneumonia pattern than in those without (p=0.007). The clinical features and CT findings did not differ significantly. CT image analysis showed that patients with S. pneumoniae pneumonia exhibited the bronchopneumonia and airspace pneumonia patterns with equal frequency. Bronchopneumonia pattern was less common in patients with preexisting emphysema. (author)

    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.

    The objective of this study was to verify the incidence of nosocomial pneumonia in intubated and extended mechanically ventilated patients having endotracheal suctioning by an open vs. closed suction method aiming to decrease nosocomial pneumonia. Twenty-four (51.1%) patients received open-tracheal suction and 23 (48.9%) received closed-tracheal suction. The inclusion criteria were: surgical and medical patients older than 13 years, undergoing mechanical ventilation for more than 48 hours. Additional data were gathered using the Acute Physiology and Chronic Health Evaluation II, and details on smoking, alcoholism, diabetes mellitus, renal failure, previous lung disease, and previous use of antibiotics, steroids, H2 antagonists and antacids. Among the 24 patients having open-tracheal suction, 11 developed nosocomial pneumonia while of the 23 patients undergoing closed-tracheal suction, seven developed infection (P = 0.278). Risk factors for nosocomial pneumonia were not significantly different between the two groups. In the final logistical regression model the following variables remained: groups (open and closed) [odds ratio (OR) = 0.014; confidence interval (CI) = 0.001-0.416; P = 0.014] and use of prior antibiotics (OR = 2.297; CI = 1.244-4.242; P = 0.008). Use of a closed suction system did not decrease the incidence of nosocomial pneumonia when compared with the open system. The exogenous risk factors were the most important for acquiring this infection. PMID:12790861

    Introduction Lower respiratory infections (LRIs) and pneumonia are among the leading causes of death worldwide, especially in children aged under 5 years, and these patterns are reflected in the South African population. Local epidemiological data for LRIs and pneumonia are required to inform the Second National Burden of Disease Study underway in South Africa. The aim of this systematic review is to identify published studies reporting the prevalence, incidence, case fatality, duration or severity of LRI and pneumonia in adults and children in South Africa. Methods and analysis Electronic database searches will be conducted to obtain studies reporting on the prevalence, incidence, case fatality, duration and severity of LRI and pneumonia in South Africa between January 1997 and December 2015. Studies that are assessed to have moderate or low risk of bias will be included in a meta-analysis, if appropriate. Where meta-analysis is not possible, the articles will be described narratively. Subgroup analysis (eg, age groups) will also be conducted where enough information is available. Ethics and dissemination This systematic review will only include published data with no linked patient-level information; thus, no ethics approval is required.

    In 1978, 89 patients were treated for (S. pneumoniae) pneumonia at New York Hospital-Cornell Medical Center. Only 40 cases met rather strict diagnostic criteria. Of these, 12 demonstrated the classical consolidative (air space) pattern usually ascribed to this disease. A bronchopneumonic (patch) pattern was demonstrated in an equal number of patients; interstitial (irregular linear) infiltrates were manifest in nine cases and a mixed interstitial and patchy presentation shown in seven cases. Absence of the consolidative pattern does not exclude pneumococcal pneumonia. Bacteriologic investigation is required to determine the proper diagnosis and course of therapy.

    This article reviews patient's own risk factors for perioperative aspiration pneumonia. Maintaining the function of the lower esophageal sphincter (LES), the airway protective reflex, and the oral hygiene are the most important to prevent the pneumonia. The LES is adversely affected by excessive stomach distention, some medication given in perioperative periods, and habitual smoking, as well as pathological status such as esophageal hiatus hernia and achalasia. Postapoplectic patients may have insufficient airway protective reflex including swallowing and laryngeal reflex. It is emphasized that the perioperative oral care is increasing in its importance for the prevention of aspiration pneumonia. PMID:27004381

    Full Text Available Mycoplasma pneumonia is a common respiratory pathogen that produces diseases of varied severity ranging from mild upper respiratory tract infection to severe atypical pneumonia. Apart from respiratory tract infections, this organism is also responsible for producing a wide spectrum of non-pulmonary manifestations including neurological, hepatic, cardiac diseases, hemolytic anemia, polyarthritis and erythema multiforme. This review focuses on molecular taxonomy, biological characteristics, epidemiology, clinical presentation, radiology and various laboratory tools in diagnosis, differential diagnosis, treatment and prevention of mycoplasma pneumonia.

    2013-07-01

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

  6. Pseudomona pseudomallei community acquired pneumonia

    International Nuclear Information System (INIS)

    This is the first published case report en Colombia about pseudomona pseudomallei community acquired pneumonia. This uncommon pathogen is from the epidemiological standpoint a very important one and medical community should be aware to look after it in those patients where no other etiological pathogen is recovered. A brief summary about epidemiology is showed, emphasizing those regions where it can be found. Likewise, comments about the differential diagnosis are important since it should be considered in those patients where tuberculosis is suspected. This is particularly representative for countries with high tuberculosis rates. Furthermore, a microbiological review is shown, emphasizing on isolation techniques, descriptions about therapeutics and other regarding treatment issues according international standards. Finally; a description about the clinical picture, laboratory findings, treatment and evolution of the case reported are shown for discussion

    Coccidioidomycosis is a well-known infection in the southwestern United States, and its occurrence is becoming more frequent in endemic areas. This disease can have a significant economic and medical impact; therefore, accurate diagnosis is crucial. In conjunction with patient symptoms, residence in or travel to an endemic area is essential for diagnosis. Diagnosis is usually made with serology, culture, or biopsy and confirmed with DNA probe technology. Pulmonary disease is the most common presentation and is seen in almost 95% of all cases. One-half to two-thirds of all Coccidioides infections are asymptomatic or subclinical. Most pulmonary infections are self-limited and do not require treatment except in special populations. When treatment is warranted, itraconazole and fluconazole are frequently used. Diffuse miliary pneumonia is uncommon and is especially rare in immunocompetent patients. Herein we describe a rare presentation of miliary coccidioidomycosis in a nonimmunocompromised patient. PMID:26722164

    Klebsiella species is the second most commonly isolated gram-negative organism in sepsis and a frequent causative pathogen in pneumonia. The receptor for advanced glycation end products (RAGE) is expressed on different cell types and plays a key role in diverse inflammatory responses. We here aimed to investigate the role of RAGE in the host response to Klebsiella (K.) pneumoniae pneumonia and intransally inoculated rage gene deficient (RAGE-/-) and normal wild-type (Wt) mice with K. pneumoniae. Klebsiella pneumonia resulted in an increased pulmonary expression of RAGE. Furthermore, the high-affinity RAGE ligand high mobility group box-1 was upregulated during K. pneumoniae pneumonia. RAGE deficiency impaired host defense as reflected by a worsened survival, increased bacterial outgrowth and dissemination in RAGE-/- mice. RAGE-/- neutrophils showed a diminished phagocytosing capacity of live K. pneumoniae in vitro. Relative to Wt mice, RAGE-/- mice demonstrated similar lung inflammation, and slightly elevated-if any-cytokine and chemokine levels and unchanged hepatocellular injury. In addition, RAGE-/- mice displayed an unaltered response to intranasally instilled Klebsiella lipopolysaccharide (LPS) with respect to pulmonary cell recruitment and local release of cytokines and chemokines. These data suggest that (endogenous) RAGE protects against K. pneumoniae pneumonia. Also, they demonstrate that RAGE contributes to an effective antibacterial defense during K. pneumoniae pneumonia, at least partly via its participation in the phagocytic properties of professional granulocytes. Additionally, our results indicate that RAGE is not essential for the induction of a local and systemic inflammatory response to either intact Klebsiella or Klebsiella LPS. PMID:26824892

    2014-10-01

    Pneumonia is one of the most important diseases in terms of mortality in the elderly. In particular, bedridden patients who are forbidden oral ingestion during enteral nutrition may have a poor outcome resulting from a respiratory infection. Oral hygiene can play a positive role in preventing aspiration pneumonia in the elderly. The aim of this study was to investigate the effectiveness of oral hygiene for bedridden and tube-fed patients at an increased risk of pneumonia. This retrospective study was conducted from July 2011 to June 2013 on a long-term-care hospital unit. The oral care protocol (OCP) intervention commenced in July 2012, during the study period. The subjects of this study were 63 elderly patients with a mean age of 81.7 years. Thirty-one patients were enrolled in the OCP intervention group, and the mean observation length was 130.4 days; the mean observation length for the 32 patients in the control group was 128.4 days. The incidence of pneumonia and the numbers of days with a recorded fever, antibiotics administration, blood tests, and radiological examinations were reduced from 1.20 to 0.45, 24.57 to 17.48, 25.52 to 10.12, 10.91 to 6.54, and 6.33 to 3.09 %, respectively. These reductions were significantly less in the OCP intervention group. In conclusion, the results of the present study suggest that daily oral care for tube-fed patients who do not receive nutrition by mouth reduced the incidence of pneumonia. In addition to patients consuming food by mouth, all tube-fed patients require dedicated oral care to maintain healthy oral conditions.

  15. Air pollution and anemia as risk factors for pneumonia in ecuadorian children: a retrospective cohort analysis

    2011-11-01

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

    To reduce the burden of fracture, not only does bone fragility need to be addressed, but also injury prevention. Thus, fracture epidemiology irrespective of degree of trauma is informative. We aimed to determine age-and-sex-specific fracture incidence rates for the Barwon Statistical Division, Australia, 2006-2007. Using radiology reports, incident fractures were identified for 5342 males and 4512 females, with incidence of 210.4 (95 % CI 204.8, 216.2) and 160.0 (155.3, 164.7)/10,000/year, respectively. In females, spine (clinical vertebral), hip (proximal femoral) and distal forearm fractures demonstrated a pattern of stable incidence through early adult life, with an exponential increase beginning in postmenopausal years for fractures of the forearm followed by spine and hip. A similar pattern was observed for the pelvis, humerus, femur and patella. Distal forearm, humerus, other forearm and ankle fractures showed incidence peaks during childhood and adolescence. For males, age-related changes mimicked the female pattern for fractures of the spine, hip, ribs, pelvis and humerus. Incidence at these sites was generally lower for males, particularly among the elderly. A similar childhood-adolescent peak was seen for the distal forearm and humerus. For ankle fractures, there was an increase during childhood and adolescence but this extended into early adult life; in contrast to females, there were no further age-related increases. An adolescent-young adult peak incidence was observed for fractures of the face, clavicle, carpal bones, hand, fingers, foot and toe, without further age-related increases. Examining patterns of fracture provides the evidence base for monitoring temporal changes in fracture burden, and for identifying high-incidence groups to which fracture prevention strategies could be directed.

    Antihypertensive drug therapy is used in children primarily to treat secondary forms of hypertension, because the prevalence of essential hypertension in the first decade of life is considerably less than 1% of the childhood population. This prevalence increases during the second decade of life, but the percentage of teenagers with essential hypertension continues to be low. Pharmaceutical companies have been able to target drug development to specific physiologic and biochemical systems. The converting enzyme inhibitors and calcium-channel blockers have greatly improved the success of therapy concomitant with a reduction in the incidence of adverse effects. The result has been a major change during the past decade in the recommendations for antihypertensive drug therapy. PMID:8417406

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

  20. Imaging findings of measles pneumonia in adults

    International Nuclear Information System (INIS)

    Objective: To illustrate the chest radiography and MSCT findings of measles pneumonia in adults. Methods: One hundred and sixty three measles patients underwent chest radiography, MSCT was performed in 3 of them. Measles pneumonia was confirmed in 10 patients (6.13%). Results: Eight of 10 patients had abnormal appearances in initial chest radiography. The characteristic chest radiographic findings were ground-glass opacities (n=6) and bronchial wall thickening (n=2). MSCT showed bilateral multiple ground-glass opacities in 1 patient, unilateral patchy ground-glass opacities with lobular distribution in the right upper lung in 2 patients. Conclusions: Familiarizing with radiographic and MSCT appearances of measles pneumonia in adults is very important for the differential diagnosis and appropriate management of measles pneumonia. Normal initial chest radiography cannot exclude the involvement of the lungs. (authors)

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

    The exogenous lipoid pneumonia, uncommon in adults, is the result of the inhalation and/or aspiration of lipid material into the tracheobronchial tree. This is often confused with bacterial pneumonia and pulmonary tuberculosis due to a nonspecific clinical and radiologic picture. It presents acutely or chronically and may result in pulmonary fibrosis. We describe here a case of lipoid pneumonia in a gas station attendant who siphoned gasoline to fill motorcycles; he was hospitalized due to presenting with a respiratory infection that was hard to resolve. The patient underwent bronchoscopy with bronchoalveolar lavage, which, on cytochemical (oil red O) evaluation, was slightly positive for lipid material in the foamy cytoplasm of alveolar macrophages. Due to his occupational history and radiographic abnormalities suggestive of lipoid pneumonia, a lung biopsy was performed to confirm the diagnosis. The patient was serially treated with segmental lung lavage and showed clinical, functional, and radiological improvement. PMID:25374742

    Exogenous lipoid pneumonia (ELP) is a rare (incidence 1.0%-2.5%), often under-diagnosed disease, caused by the aspiration and accumulation of exogenous lipids within the pulmonary alveoli. Various cases have been described due to inhalation of lubricants via the nasal passages and oropharynx, aspiration of mineral oils in laxatives in patients with eating disorders, application of lip gloss, occupational exposure to liquid paraffin or mineral oils ("fire-eaters", industrial use in washing of machinery, automobile workshops, plastic paints, etc.) and application of Vaseline during the insertion of nasogastric tubes and in the care of tracheotomy patients. ELP usually presents radiologically as areas of low-attenuation peribronchial consolidation and ground glass opacities, with a predominantly bibasal distribution. We present 5 cases of long-standing laryngectomy patients diagnosed with ELP who admitted using Vaseline in their tracheal stoma care. PMID:25446870

    1996-02-01

    During 12 months in 1981-82, 201 children were hospitalized due to radiologically verified definite or probable pneumonia. In 1985, 194 chest radiographs (anteroposterior views) were re-evaluated jointly by two radiologists, and classified into three categories: alveolar, interstitial and probable pneumonia. In 127 cases definite pneumonia was diagnosed on both occasions, alveolar in 48 cases and interstitial in 79 cases. Variation between the two evaluations 3 years apart was observed in 46 (24%) of the 194 cases; the adjusted kappa (0.47) was in the modest region. Factors contributing to this variation were young age, less than 12 months, and the presence of interstitial infiltration, bronchial obstruction and low C-reactive protein. Factors associated with less marked variation were the presence of alveolar infiltration, auscultatory fine rates and elevated C-reactive protein. The microbial aetiology of infection, assessed by viral and bacterial antigen and antibody assays, showed no association with diagnostic variation. A lateral view of the chest radiograph was obtained from 158 patients; it was positive in 99 (91%) of the 109 cases with definite pneumonia. In only three cases the diagnosis was based on the lateral view alone. Our results show that the radiological diagnosis of pneumonia is difficult in children, especially in young children with interstitial pneumonia. PMID:8932509

  10. Acute and subacute idiopathic interstitial pneumonias.

    Science.gov (United States)

    Taniguchi, Hiroyuki; Kondoh, Yasuhiro

    2016-07-01

    Idiopathic interstitial pneumonias (IIPs) may have an acute or subacute presentation, or acute exacerbation may occur in a previously subclinical or unrecognized chronic IIP. Acute or subacute IIPs include acute interstitial pneumonia (AIP), cryptogenic organizing pneumonia (COP), nonspecific interstitial pneumonia (NSIP), acute exacerbation of idiopathic pulmonary fibrosis (AE-IPF) and AE-NSIP. Interstitial lung diseases (ILDs) including connective tissue disease (CTD) associated ILD, hypersensitivity pneumonitis, acute eosinophilic pneumonia, drug-induced lung disease and diffuse alveolar haemorrhage need to be differentiated from acute and subacute IIPs. Despite the severe lack of randomized controlled trials for the treatment of acute and subacute IIPs, the mainstream treatment remains corticosteroid therapy. Other potential therapies reported in the literature include corticosteroids and immunosuppression, antibiotics, anticoagulants, neutrophil elastase inhibitor, autoantibody-targeted treatment, antifibrotics and hemoperfusion therapy. With regard to mechanical ventilation, patients in recent studies with acute and subacute IIPs have shown better survival than those in previous studies. Therefore, a careful value-laden decision about the indications for endotracheal intubation should be made for each patient. Noninvasive ventilation may be beneficial to reduce ventilator associated pneumonia. PMID:27123874

    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.

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

    Full Text Available Background Pneumonia is a health problem in developing countries, often caused by bacterial agents. The widespread use of cefotaxime, a third-generation of cephalosporin to increased incidence of resistance to this antibiotic. Several studies have reported on risk factors associated with resistance to cefotaxime. Objective To oidentify risk factors for cefoxime resistence in children with pneumonia. Methods We performed a case-control study at Sanglah Hospital between January 2006-December 2010. The case group included children with blood culture-positive pneumonia and resistance to cefoxime by sensitivity test. The control group was selected from the same population as the case group, but the bacteria isolated from these subjects were sensitive to cefotaxime: age <3 years, microorganism species, history of antimicrobial use, and history of hospitalization within the prior 3 months. Chi square test and logistic regression analysis were performed to determine any associations between the four potential risk factors and resistance to cefoxime. A P<0.05 was considered to be statistically significant. Results Univariate analysis showed that the risk factors for resistence to efoxime were history of antimicrobial use in the prior 3 months (OR 2.79; 95%CI 1.40 to 5.55; P=0.001 and history of hospitalization within the prior 3 months (OR 5.57; 95%CI 1.95 to 15.87; P=<0.0001. By multivariate analysis, risk factors associated with resistance to cefotaxime were history of antimicrobial use in the prior 3 months((OR 2.4; 95%CI 1.18 to 4.86; P=0.015, history of hospitalization within the prior 3 motnhs (OR 4.7; 95%CI 1.62 to 13.85; P0.004, and history of breastfeeding for less than 2 months (OR 2.3; 95%CI 1.0 to 5.4; P=0.042. Conclusion History of antimicrobial use and history of hospitalization within the prior 3 months were significant risk factors for resistance to cefoxime in children with pneumonia.

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

    Previous studies have led to the hypothesis that the gross hepatic copper storage characteristic of Indian childhood cirrhosis (ICC) is due to the early introduction of animal milk feeds which have been contaminated with copper from brass household utensils. Amongst the families of 100 cases of ICC, the incidence of ICC in children born after dietary advice had been given (1/86) was significantly lower than in older siblings (12/125). This study attempted to document the incidence of ICC and the usage of brass before and after an intervention programme in Pune District advising against this pattern of infant feeding. The study encountered numerous difficulties in data gathering, but documented a fall in ICC prevalence resulting in its virtual disappearance in Pune District. This contrasted with an unchanged incidence in Chandigarh. Although a fall in brass usage was seen in Pune District, this was actually a spontaneous sociological change rather than a result of health education. PMID:1376582

    2014-06-01

    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.

    Full Text Available Objectives. Study of multi-resistant Klebsiella pneumoniae strains isolated from blood cultures collected from in-patients of hospitals located in eastern Liguria, and evaluation of the susceptibility to carbapenems and other antibiotics by E-test and automated methods. Methods. At the Laboratory of Clinical Microbiology, of Lavagna Hospital in eastern Liguria, 397 Klebsiella pneumoniae strains were collected from in-patients from different wards of hospitals sites, during the year 2011. They included 115 isolates from blood cultures (aerobic and anaerobic and various biological materials. All strains were tested in the laboratory for their susceptibility to antibiotics. Results. Of the 115 strains of Klebsiella pneumoniae collected from blood cultures 59.1% showed resistance to imipenem, ertapenem, meropenem. Conclusions. The data show a high incidence of resistance to carbapenems in Klebsiella pneumoniae isolated from blood cultures.This is important to implement surveillance programs for control and prevention, but also reduce the intake of antibiotics when they are not strictly necessary.

    Full Text Available Background. Streptococcus pneumoniae can cause a wide spectrum of disease, including invasive pneumococcal disease (IPD. From 2005 to 2009 an outbreak of IPD occurred in Western Canada, caused by a S. pneumoniae strain with multilocus sequence type (MLST 289 and serotype 5. We sought to investigate the incidence of IPD due to this S. pneumoniae strain and to characterize the outbreak in British Columbia using whole-genome sequencing. Methods. IPD was defined according to Public Health Agency of Canada guidelines. Two isolates representing the beginning and end of the outbreak were whole-genome sequenced. The sequences were analyzed for single nucleotide variants (SNVs and putative genomic islands. Results. The peak of the outbreak in British Columbia was in 2006, when 57% of invasive S. pneumoniae isolates were serotype 5. Comparison of two whole-genome sequenced strains showed only 10 SNVs between them. A 15.5 kb genomic island was identified in outbreak strains, allowing the design of a PCR assay to track the spread of the outbreak strain. Discussion. We show that the serotype 5 MLST 289 strain contains a distinguishing genomic island, which remained genetically consistent over time. Whole-genome sequencing holds great promise for real-time characterization of outbreaks in the future and may allow responses tailored to characteristics identified in the genome.

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

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

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

    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 Extensive reviews of pulmonary infections in AIDS have reported few herpetic infections. Generally these infections are due to Herpes simplex type 1. Pneumonia due to herpes type 2 is extremely rare. We describe a 40 year-old HIV positive woman who complained of fever, cough and dyspnea for seven years. She had signs of heart failure and the appearance of her genital vesicles was highly suggestive of genital herpes. Echocardiography showed marked pulmonary hypertension, right ventricular hypertrophy and tricuspid insufficiency. After a few days of hospitalization she was treated with Aciclovir and later with Ganciclovir. An open pulmonary biopsy revealed an interstitial inflammation, localized in the alveolar walls. Some pulmonary arteries had widened walls and focal hyaline degeneration. Immunohistochemistry indicated that the nuclei had herpes simplex virus type 2 in many endothelial cells (including vessels with widened walls, macrophages in the alveolar septa and pneumocytes. There was clinical improvement after treatment for herpes. We concluded that as a consequence of herpes infection, endothelial involvement and interstitial inflammation supervene, with thickening of vascular walls and partial obliteration of the vessel lumen. A direct consequence of these changes in pulmonary vasculature was pulmonary hypertension followed by heart failure.

    1992-07-01

    Chlamydia pneumoniae, a newly described Chlamydia species, has been shown to be a cause of acute respiratory tract infection in both adults and children, but its role in human infection is still under investigation. Here we present a family outbreak of C. pneumoniae infection where three members of a family presented with a 'flu-like illness' and acute upper respiratory tract infection which did not improve despite penicillin or septrin therapy. No history of exposure to birds, pets or animals was obtained. As C. pneumoniae isolation from respiratory secretions is not without difficulty, diagnosis usually relies currently on serum-based tests. In this study C. pneumoniae specific IgM determined by the micro-immunofluorescence test was detected in the three clinical cases. All three cases had an elevated complement-fixing antibody titre to Psittacosis-LGV antigen, which may have suggested psittacosis, if type-specific tests had not been performed. In addition, three other members of the family had C. pneumoniae-specific IgG antibody although specific IgM was absent. These three younger members of the family had been symptomatic in the month preceding symptoms in their older sibling and their parents. All the symptomatic members of the family made a complete recovery on tetracycline therapy. PMID:1522345

Material and Methods: A double helical CT was performed in 6 patients referred to our center because of a chest X-ray with pulmonary infiltrates. Clinical presentation was cough, fever and eosinophilia in peripheral blood. Patients' age ranged from 25 to 55 years; 4 were women and 2 were men, one of the latter had a history of bronchial asthma. All patients received treatment with corticosteroids, with remission of the clinical and radiological parameters. Three patients underwent a control CT. Results: Findings consisted in focal parenchymal alterations, with areas of pulmonary consolidation and areas of 'ground glass' appearance; both patterns coexisted in certain areas. In 3 cases the lesions extended from the apices to the pulmonary bases, with predominance of the upper and middle fields. In 1 patient, there was frank predominance in the left hemi thorax. In another patient, who had a history of asthma, there were signs of pulmonary hyperinflation, with diffuse thickening of the bronchial walls, added to the previously mentioned findings, which involved the entire lung. In the mediastinum, 1 patient had lymph nodes larger than 1 cm, 3 had lymph nodes that were not enlarged but were more numerous than usual, and in the remaining patients no lymph nodes were found. The control CT's showed almost total resolution of the pulmonary infiltrates. Conclusion: The combination of eosinophilia and characteristic pulmonary infiltrates with a likely clinical presentation, associated with an optimal response to treatment with corticosteroids allows to make a reliable diagnosis and avoids the need for a pulmonary biopsy.

    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 In an era when Haemophilus influenzae type b (Hib conjugate vaccine is widely used, the incidence of Hib as a cause of community-acquired pneumonia (CAP has dramatically declined. Non-typeable H. influenzae (NTHi strains and, occasionally, other encapsulated serotypes of H. influenzae are now the cause of the majority of invasive H. influenzae infections, including bacteraemic CAP. NTHi have long been recognised as an important cause of lower respiratory tract infection, including pneumonia, in adults, especially those with underlying diseases. The role of NTHi as a cause of non-bacteraemic CAP in children is less clear. In this review the evidence for the role of NTHi and capsulated strains of H. influenzae will be examined.

    Endogenous lipoid pneumonia is an uncommon condition. This is a report of a 29-year-old woman diagnosed with endogenous lipoid pneumonia associated with Legionella pneumophila serogroup 1 infection. The patient's endogenous lipoid pneumonia resolved completely after treatment for Legionella pneumophila infection. This suggests that early diagnosis and aggressive treatment of the underlying infection may prevent any long-term sequelae of lipoid pneumonia. PMID:23546039

    International Nuclear Information System (INIS)

    Objective: To analyze the CT, especially HRCT appearance of localized organizing pneumonia. Methods: The CT scans of nine patients with histologically proved localized organizing pneumonia were studied retrospectively. Results: The size of the lesions in nine cases varied from 2 to 4 cm (average 2.5 cm). Eight lesions were located in the peripheral lung parenchyma near the pleural surface. The lesions were detected as round in four, anomaly in five. The margin of six lesions had inward bow indentation. Infiltrating lesions in surrounding structures were found in four cases. Conclusion: The CT, especially HRCT appearance of localized organizing pneumonia shows some features that can make most of them to be differentiated from other lesions

    We report a case of lipoid pneumonia treated in our Health Centre. It is a disease that occurs rarely, but is important in Primary Care. This condition has been known since 1925, when it was first described by Laughlen, who described a case of lipoid pneumonia secondary to an injection of oil in the nasopharyngeal area. Today it is a rarity, and it is most frequently associated with the use of oil-based nasal drops (which are now decreasing in use). Its aetiology may be endogenous or exogenous. Although the pathological diagnosis is generally the most important, sometimes a lesion in the chest X-ray can lead us to suspect it due to the patient's history. This was a case of acute lipoid pneumonia in a young patient, who periodically performed as a "fire eater". PMID:23452539

    The current emergence of antibiotic-resistant bacteria causes major problems in hospitals worldwide. To survive within the host, bacterial pathogens exploit several escape mechanisms to prevent detection and killing by the immune system. As a major player in immune defense, the complement system recognizes and destroys bacteria via different effector mechanisms. The complement system can label bacteria for phagocytosis or directly kill Gram-negative bacteria via insertion of a pore-forming complex in the bacterial membrane. The multi-drug resistant pathogen Klebsiella pneumoniae exploits several mechanisms to resist complement. In this review, we present an overview of strategies used by K. pneumoniae to prevent recognition and killing by the complement system. Understanding these complement evasion strategies is crucial for the development of innovative strategies to combat K. pneumoniae. PMID:27364766

  16. Radiographic findings of mycoplasma pneumonia in adult

    International Nuclear Information System (INIS)

    Mycoplasma pneumonia has known to be a not uncommon disease. However, the differential diagnosis of mycoplasm pneumonia with other viral pneumonia is difficult because of its variable clinical symptoms and atypical radiologic findings. A retrospective review was made of plain chest radiologic findings and clinical manifestations of 33 patients, who were admitted at Yonsei University Hospital from January, 1985 to February, 1990. The most prevalent age was 4th decade (33%) and main symptoms were cough (24/33), fever (2/33) and sputum (20/22). The most frequent season was winter (50%). The radiologic patterns were predominently interstitial (15/33), combined (13/33) and predominently alveolar (5/33) lesion. In alveolar infiltration cases (n 18), unilateral single lobe involvement was the most common (17/18) and left lower lobe (8/18) was predominently involved. Associated radiologic findings were hilar lymphadenopathy (4/33), pleural effusion (4/33) and cardiomegaly (7/33)

    Full Text Available Reduced susceptibility to carbapenems in Gram-negative pathogens is an emerging feature of the antibiotic-resistance phenomenom Reports about strains resistant to this class of antibiotics among Enterobacteriaceae, particularly in Klebsiella pneumoniae, are increasing.The aims of this study were to assess the incidence of Klebsiella pneumoniae with reduced susceptibility to carbapenems in Bologna area and to carry out the characterization of these strains.The study included isolates of K. pneumoniae that showed reduced susceptibility to carbapenems, as detected by an automated system (Vitek2, bioMérieux. Between January and May 2009, 26 strains were collected (mainly isolated from urinary samples.These isolates were tested for susceptibility to carbapenems by E-test, to define MIC values for meropenem and ertapenem. Moreover, to detect the production of metallo-beta lactamases (MBL and carbapenemases (KPC were respectively performed the Etest with imipenem and imipenem/EDTA (IPM-IPM/EDTA and the modified Hodge test. Susceptibility assays performed by E-test showed that 25/26 strains were susceptible to meropenem, while for ertapenem 20/26 strains resulted resistant.The modified Hodge test was positive for 1 strain, while all the isolates were negative to the IPM-IPM/EDTA E-test.These results show that, as recently reported, the majority of strains of K. pneumoniae exhibiting reduced susceptibility to carbapenems, especially to ertapenem, are characterized by the production of ESBLs, which likely is associated with the loss of porins. On the other side, one strain was found to produce KPC and this finding confirms that the diffusion of carbapenemases producing K. pneumoniae has also to be considered in this geographic area.

  18. Acute solitary localized pneumonia: CT diagnosis

    International Nuclear Information System (INIS)

    Objective: To evaluate CT in the differential diagnosis of solitary localized pneumonia. Method: Only plain CT without contrast study was done because of different types of CT scanners weed. There were 25 cases with localized pneumonia with initial diagnosis as suspected peripheral bronchogenic carcinoma. All patients were over forty years of age, 84% 50-80 years, 13(52%) patients were asymptomatic, 5(20%) patients had bloody sputum. Results: The CT features were divided into three patterns: (1) irregular nodule with relatively well-defined margin, ground-glass opacity and a few punctuate high densities. (2) irregular nodule with sharply circumscribed, spiculate border and homogeneous density. (3) regular nodule with relatively well-defined margin, and homogeneous density. The third type was most frequent (60%) with predilection for the dorsal segments of the lower lobes, or the posterior basal segments. Of the 25 patients 3 had operation, the remaining cases were treated as pneumonia, the lesions were resolved in 18(82%) patients in 2-3 weeks. Conclusions: Sometimes it is very difficult to differentiate localized pneumonia from peripheral lung cancer on the basis of clinical presentation and imaging. The spiculate margins of irregular nodule shown on CT could be indeterminate on chest radiography, and as a result chest radiograph is helpful in differential diagnosis of localized pneumonia. Change in size of the lesion as observed at the same cross-section scan, smaller at mediastinal window than at lung window is in favor of localized pneumonia, however, with the exception of alveolar carcinoma, treatment with antibiotic therapy for a period of 2-3 weeks, helps differentiate these diseases

  19. Epidemiology and Virulence of Klebsiella pneumoniae.

    Strains of Klebsiella pneumoniae are frequently opportunistic pathogens implicated in urinary tract and catheter-associated urinary-tract infections of hospitalized patients and compromised individuals. Infections are particularly difficult to treat since most clinical isolates exhibit resistance to several antibiotics leading to treatment failure and the possibility of systemic dissemination. Infections of medical devices such as urinary catheters is a major site of K. pneumoniae infections and has been suggested to involve the formation of biofilms on these surfaces. Over the last decade there has been an increase in research activity designed to investigate the pathogenesis of K. pneumoniae in the urinary tract. These investigations have begun to define the bacterial factors that contribute to growth and biofilm formation. Several virulence factors have been demonstrated to mediate K. pneumoniae infectivity and include, but are most likely not limited to, adherence factors, capsule production, lipopolysaccharide presence, and siderophore activity. The development of both in vitro and in vivo models of infection will lead to further elucidation of the molecular pathogenesis of K. pneumoniae. As for most opportunistic infections, the role of host factors as well as bacterial traits are crucial in determining the outcome of infections. In addition, multidrug-resistant strains of these bacteria have become a serious problem in the treatment of Klebsiella infections and novel strategies to prevent and inhibit bacterial growth need to be developed. Overall, the frequency, significance, and morbidity associated with K. pneumoniae urinary tract infections have increased over many years. The emergence of these bacteria as sources of antibiotic resistance and pathogens of the urinary tract present a challenging problem for the clinician in terms of management and treatment of individuals.

    Objective This paper describes a natural language processing system for the task of pneumonia identification. Based on the information extracted from the narrative reports associated with a patient, the task is to identify whether or not the patient is positive for pneumonia. Design A binary classifier was employed to identify pneumonia from a dataset of multiple types of clinical notes created for 426 patients during their stay in the intensive care unit. For this purpose, three types of features were considered: (1) word n-grams, (2) Unified Medical Language System (UMLS) concepts, and (3) assertion values associated with pneumonia expressions. System performance was greatly increased by a feature selection approach which uses statistical significance testing to rank features based on their association with the two categories of pneumonia identification. Results Besides testing our system on the entire cohort of 426 patients (unrestricted dataset), we also used a smaller subset of 236 patients (restricted dataset). The performance of the system was compared with the results of a baseline previously proposed for these two datasets. The best results achieved by the system (85.71 and 81.67 F1-measure) are significantly better than the baseline results (50.70 and 49.10 F1-measure) on the restricted and unrestricted datasets, respectively. Conclusion Using a statistical feature selection approach that allows the feature extractor to consider only the most informative features from the feature space significantly improves the performance over a baseline that uses all the features from the same feature space. Extracting the assertion value for pneumonia expressions further improves the system performance. PMID:22539080
