    Full Text Available A pneumonia adquirida na comunidade (PAC é a principal causa de morte devido a doença infecciosa no mundo ocidental, sendo responsável por um número superior a 20 hospitalizações/ano por mil habitantes. As guidelines internacionais preconizam a antibioterapia combinada, como seja a associação de um â-lactâmico e de um macrólido no tratamento inaugural da PAC grave. Tal facto implica a utilização de cuidados de saúde oneroso e o consumo elevado de antibióticos, contribuindo, assim, para o aparecimento de resistências bacterianas. Nos EUA, os custos do tratamento da PAC excedem os doze biliões de dólares e, em muitos países desenvolvidos, observa-se um aumento da resistência aos macrólidos. Uma vez determinada a etiologia da PAC, a antibioterapia direccionada para o agente patogénico em causa pode ser iniciada. No entanto, até agora, não foi encontrada um biomarcador suficientemente sensível e específico para orientar a terapêutica inaugural, devendo ser criados protocolos com essa finalidade. Os autores do presente trabalho estudaram a relevância da determinação consecutiva da proteína C reactiva (PCR no follow-up de doentes com PAC, avaliando o valor preditivo da normalização tardia dos níveis séricos da PCR relativamente ao risco de administração de antibioterapia inapropriada e a um prognóstico desfavorável. Trata-se de um estudo prospectivo multicêntrico controlado conduzido em cinco hospitais universitários holandeses, entre Junho de 2000 e Julho de 2003, sobre a eficácia clínica da instituição empírica de terapêutica antibiótica intravenosa ou oral na PAC. A PAC foi definida pela presença de, pelo menos, dois sintomas de infecção respiratória baixa aguda antes da admissão hospitalar e de um infiltrado pulmonar “de novo” ou em progressão na radiografia do tórax. A classificação como grave está relacionada com um scoreno índice de gravidade PSI - Pneumonia severity index >90 ou de

    A retrospective study of 1011 hospitalized patients with pneumonia was undertaken to assess the value of routine convalescent chest radiography for detection of underlying lung cancer. To investigate the mode of clinical onset of pulmonary carcinoma, 232 inpatients with this diagnosis were also studied. The findings may be summarized as follows: 1. 13/1011 pneumonia patients were found to have previously undiagnosed pulmonary carcinoma; 2. many of these carcinomas (8/13) were disclosed by an acute chest X-ray; 3. pulmonary carcinoma was found by convalescent chest X-ray in 2/88 patients not feeling well and in 2/524 patients feeling well at follow-up, and non of these 4 patients benefitted from the carcinoma diagnosis; 4. ESR was of no value in detecting underlying pulmonary carcinoma at follow-up in patients with pneumonia; 5. of the 232 patients with pulmonary carcinoma, 29 (12.5%) presented with an acute respiratory tract infection; 6. most of these latter patients did not recover as expected and their correct diagnosis was made based on a chest X-ray performed because of persistent symptoms. We suggest that patients with radiologically verified pneumonia undergo clinical examination or are interviewed 4-5 weeks after the onset. If signs or symptoms of respiratory disease persist, chest X-ray should be performed. We consider, however, that routine convalescent chest radiography with the aim of detecting any underlying pulmonary tumour could be omitted if the patient has completely recovered 1 month after the acute onset of illness.

    Opportunistic pneumonias are a life-threatening complication in patients with AIDS. Early diagnosis and therapy is necessary to improve prognosis. This study was designed to assess the value of 67 Ga scintigraphy in the primary detection and follow-up of these special pneumonias. 67 Ga scintigraphy was performed in 40 patients: 10 normal controls and 30 HIV-positive patients with AIDS or AIDS-related complex (ARC). 67 Ga scan results were compared with current chest radiographs and the results of pathogen detection. The evaluation of positive scans was based on a quantification of the pulmonary uptake, expressed as a pulmonary/soft-tissue uptake ratio. Only 8/30 patients had a normal scan, 22/30 showed diffuse (13/22) or focal (9/22) increases of pulmonary uptake. In 7/8 patients with normal scans the chest radiograph was negative as well. The one patient with negative scan but positive chest radiograph had pulmonary Kaposi's sarcoma. In 11/22 patients the 67 Ga scan and chest radiograph were positive simultaneously. In the other 11/22 patients with positive scans chest radiographs were initially negative but showed pathology in 5 cases within 1-2 weeks. The reason for positive scans in most cases was an opportunistic lung infection; other forms of pneumonia were only observed in two cases. The defined uptake ratio demonstrated to be a highly sensitive parameter for monitoring pneumonia and the effects of therapy in follow-up studies. In conclusion, quantitative 67 Ga scintigraphy proved to be a reliable and highly sensitive method for primary detection and follow-up of opportunistic pneumonias in patients with AIDS. (orig.) [de

    Necrotising pneumonia (NP) is a rare but life-threatening complication of pulmonary infection. It is characterised by progressive necrosis of lung parenchyma with cavitating foci evident upon radiological investigation. This article reports the case of a 52-year-old woman, immunocompetent healthcare professional presenting to Accident and Emergency with NP and Staphylococcus aureus septicaemia. The cavitating lesion was not identified on initial chest X-ray leading to a delay in antimicrobial optimisation. However, the patient went on to achieve a full symptomatic recovery in 1 month and complete radiological recovery at 2-year follow-up. Long-term prognosis for adult cases of NP currently remains undocumented. This case serves as the first piece of published evidence documenting full physiological and radiological recovery following appropriate treatment of NP in an immunocompetent adult patient. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

    Infections following a natural disaster such as an EF-5 tornado can be atypical and difficult to treat. Studies have looked at illness following several natural disasters, but few have studied respiratory illness following a tornado. A review of patients with pneumonia admitted during the period from May 22, 2009, through May 21, 2012, was completed. The Tornado Zone Group included adult patients who lived or worked in the tornado zone during the year following the tornado. Data were isolated by number of pneumonia cases within and outside the tornado zone per month per year. An analysis of variance comparing the number of pneumonia cases from the tornado zone per month per year was significant at F2,38 = 12.93 and P Tornado Zone Group (P Tornado Zone patients to be younger than controls (t390 = 5.14; P Tornado Zone Group included uncommon pathogens not isolated during the 2 years prior. The number of pneumonia cases may increase following tornadoes. Although current guidelines recommend narrow-spectrum antibiotics for community-acquired pneumonia, results of this study suggest the possible need for broader antimicrobial coverage after tornadoes.

    Full Text Available INTRODUÇÃO: O Streptococcus pneumoniae é o mais freqüente agente etiológico de infecções respiratórias adquiridas na comunidade e sua resistência aos antimicrobianos tem aumentado nos últimos anos. A determinação da resistência é feita rotineiramente por método lento que depende do crescimento em cultura e determinação da concentração inibitória mínima (CIM. A reação em cadeia da polimerase (PCR detecta os genes responsáveis pela resistência do Streptococcus pneumoniae a penicilina em cerca de 8 horas. OBJETIVO: Comparar a PCR com o método da CIM no diagnóstico da resistência da Streptococcus pneumoniae a penicilina. MÉTODO: Foram estudadas 153 amostras de Streptococcus pneumoniae, isoladas de diferentes sítios anatômicos, usando-se para detecção de mutações nos genes que codificam as proteínas ligadoras de penicilina 1a, 2b e 2x, responsáveis pela resistência à penicilina. A ocorrência das mutações foi correlacionada com a CIM de penicilina, determinada pelo teste de difusão em ágar. RESULTADOS: A resistência global à penicilina do Streptococcus pneumoniae foi de 22,8% (16,3% de resistência intermediária e 6,5% de resistência alta. Em proporções estatisticamente significativas, as amostras sensíveis à penicilina não tinham mutações, as intermediárias apenas uma, geralmente na proteína ligadora de penicilina 2x, e as altamente resistentes tinham mutações nas três proteínas investigadas. CONCLUSÃO: A PCR é um método rápido para a detecção da resistência à penicilina do Streptococcus pneumoniae, que poderá vir a ser utilizado na prática clínica.BACKGROUND: Streptococcus pneumoniae is the most common etiologic agent of community-acquired respiratory infections. In recent years, S. pneumoniae resistance to antimicrobial agents has increased. Minimum inhibitory concentration (MIC is routinely used to determine resistance.

    Abstract Objective To determine the attributable risk of community acquired pneumonia on incidence of heart failure throughout the age range of affected patients and severity of the infection. Design Cohort study. Setting Six hospitals and seven emergency departments in Edmonton, Alberta, Canada, 2000-02. Participants 4988 adults with community acquired pneumonia and no history of heart failure were prospectively recruited and matched on age, sex, and setting of treatment (inpatient or outpatient) with up to five adults without pneumonia (controls) or prevalent heart failure (n=23 060). Main outcome measures Risk of hospital admission for incident heart failure or a combined endpoint of heart failure or death up to 2012, evaluated using multivariable Cox proportional hazards analyses. Results The average age of participants was 55 years, 2649 (53.1%) were men, and 63.4% were managed as outpatients. Over a median of 9.9 years (interquartile range 5.9-10.6), 11.9% (n=592) of patients with pneumonia had incident heart failure compared with 7.4% (n=1712) of controls (adjusted hazard ratio 1.61, 95% confidence interval 1.44 to 1.81). Patients with pneumonia aged 65 or less had the lowest absolute increase (but greatest relative risk) of heart failure compared with controls (4.8% v 2.2%; adjusted hazard ratio 1.98, 95% confidence interval 1.5 to 2.53), whereas patients with pneumonia aged more than 65 years had the highest absolute increase (but lowest relative risk) of heart failure (24.8% v 18.9%; adjusted hazard ratio 1.55, 1.36 to 1.77). Results were consistent in the short term (90 days) and intermediate term (one year) and whether patients were treated in hospital or as outpatients. Conclusion Our results show that community acquired pneumonia substantially increases the risk of heart failure across the age and severity range of cases. This should be considered when formulating post-discharge care plans and preventive strategies, and assessing downstream episodes

    Streptococcus pneumoniae infection is the most common cause of community-acquired pneumonia in adults. Invasive pneumococcal disease (IPD) carries a high case fatality rate. We investigated the lifespan of adults who recovered from IPD during a 32-year follow-up. We determined whether adults discharged after an episode of IPD from hospitals affiliated with the Marshall University Joan C. Edwards School of Medicine in Huntington, West Virginia from 1983-2003 were alive on June 30, 2014. Lifespan was assessed by Kaplan-Meier methodology, Cox proportional hazards multivariate analysis, life expectancy using life tables for West Virginia, years of potential life lost and serotype occurrence. The study group comprised 155 adults who survived IPD. They had a mean age at discharge of 64.6 years, mean lifespan after IPD of 7.1 years, mean expected lifespan after IPD of 17.0 years, mean age at death of 71.6 years and a mean life expectancy of 81.6 years. Only 14 (9.0%) patients lived longer than their life expectancy. Of the 13 comorbid diseases analyzed, cancer and neurologic diseases and the number of comorbid diseases suffered by each patient were the significant variables associated with survival. The mean years of potential life lost was 9.936 years. Only serotype 12 of 31 serotypes recovered occurred more often in patients who survived for 11 or more years after discharge (relative risk = 3.44, 95% CI: 1.19-9.95). The fact that most adult patients who recovered from IPD died before their documented life expectancy argues for the pernicious severity of IPD and the importance of immunization of adults with pneumococcal vaccines.

    2018-01-01

    Full Text Available A teenage girl was evaluated for recurrent right pneumonia. The evaluation revealed a calcified mediastinal mass that compressed the right intermediate and middle lobar bronchi, as well as the right pulmonary artery and veins. The clinical picture together with imaging studies and borderline positive serology testing suggested a diagnosis of fibrosing mediastinitis associated with histoplasmosis. This rare condition is characterized by the local proliferation of invasive fibrous tissue within the mediastinum due to a hyperimmune reaction to Histoplasma capsulatum. Antifungal and anti-inflammatory therapies are usually ineffective, and surgical intervention contains a high morbidity risk. Palliative surgery and stenting of the compressed airway have been suggested. In the past, the prognosis was thought to be poor, but recent studies demonstrate a more positive outcome. Our patient had been radiologically and functionally stable under follow-up for over thirteen years and has married and delivered two healthy children, both following an uneventful pregnancy.

    Conclusion: LUS is a sensitive diagnostic tool with which to identify pneumonia in children. It is also useful in following up the progress of pneumonia. We suggest that LUS is a complementary tool to chest radiography in the diagnosis of pneumonia in children and that the follow up of pneumonia by LUS can reduce the exposure of children to ionizing radiation.

    The purpose of this study is to determine the incidence, risk factors, and clinical implications of pneumonia following total joint arthroplasty (TJA). The American College of Surgeons National Surgical Quality Improvement Program was used to conduct a retrospective cohort study of patients undergoing TJA. Independent risk factors for the development of pneumonia within 30 days of TJA were identified using multivariate regression. Mortality and readmission rates were compared between patients who did and did not develop pneumonia. Multivariate regression was used to adjust for all demographic, comorbidity, and procedural characteristics. In total, 171,200 patients met inclusion criteria, of whom 66,493 (38.8%) underwent THA and 104,707 (61.2%) underwent TKA. Of the 171,200 patients, 590 developed pneumonia, yielding a rate of 0.34% (95% confidence interval = 0.32%-0.37%). Independent risk factors for pneumonia were chronic obstructive pulmonary disease, diabetes mellitus, greater age (most notably ≥80 years), dyspnea on exertion, dependent functional status, lower body mass index, hypertension, current smoker status, and male sex. The subset of patients who developed pneumonia following discharge had a higher readmission rate (82.1% vs 3.4%, adjusted relative risk [RR] = 16.6, P pneumonia. Pneumonia is a serious complication following TJA that occurs in approximately 1 in 300 patients. Approximately 4 in 5 patients who develop pneumonia are subsequently readmitted, and approximately 1 in 25 die. Given the serious implications of this complication, evidence-based pneumonia prevention programs including oral hygiene with chlorhexidine, sitting upright for meals, elevation of the head of the bed to at least 30°, aggressive incentive spirometry, and early ambulation should be considered for patients at greatest risk.

CONCLUSÕES: Os dois casos de pneumonia por varicela, que apresentaram SARA e disfunções de múltiplos órgãos, obtiveram boa evolução clínica.BACKGROUNG AND OBJECTIVES: Varicella is an exantematic disease caused by varicella-zoster virus. Varicella pneumonia complicated with acute respiratory distress syndrome (ARDS is very rare in adults and is associated with high morbimortality. We report two cases of ARDS secondary to varicella-zoster virus pneumonia. CASES REPORT: We report two cases of ARDS and multiple organ dysfunction syndrome (MODS secondary to varicella-zoster virus pneumonia. A 15-year-old man with human immunodeficiency virus (HIV infection and a 29-year-old immunocompetent female were admitted in the ICU with primary varicella infection and pneumonia. Both cases progressed towards ARDS, severe thrombocytopenia and acidosis. In addition cardiovascular and renal failure occurred in the first and second patients, respectively. Treatment consisted of immediate administration of intravenous acyclovir and a lung-protective ventilation strategy. CONCLUSIONS: Both cases of varicella

    FOLFOX 4 chemotherapy (5-fluorouracil, leucovorin and oxaliplatin) is the standard adjuvant treatment for stage III colon cancer. The principal secondary effects described are haematological, gastro-intestinal or neurological. A single case of obliterative bronchiolitis with organising pneumonia has been described recently. We report the case of a female patient aged 74 years who, after 12 courses of FOLFOX 4 chemotherapy, developed acute onset of severe shortness of breath and a dry cough but remained afebrile. A thoracic CT-scan showed symmetrical bilateral interstitial infiltration that was reticular in appearance, and predominantly basal and peripheral in distribution. Broncho-alveolar lavage revealed an alveolitis with 9% eosinophils and 4% neutrophils. Transbronchial biopsies showed the appearances of obliterative bronchiolitis with organising pneumonia. Systemic corticosteroid treatment led to a remarkable clinical and functional improvement. To our knowledge, this is the second case of obliterative bronchiolitis with organising pneumonia that has been described following adjuvant treatment based on FOLFOX 4.

    To analyze CT and follow-up chest radiographic findings in patients with necrotizing pneumonia and to evaluate clinical significance of the extent of necrosis. We reviewed medical records and retrospectively analysed CT scans and follow-up chest radiographs of 22 patients with necrotizing pneumonia, confirmed by biopsy (n = 7) and culture (n = 15). Inclusion criteria for necrotizing pneumonia was necrotic low attenuation, with or without cavitation on postcontrast enhanced CT scan. The study group included 15 men and seven women, aged 11-66 years (average: 47 years). The pathogens of necrotizing pneumonia were Klebsiella spp (n = 7), Enterobacter spp (n = 5), Actinomyces spp (n = 4), Pseudomonas spp (n = 4), Nocardia spp (n = 4), and others (n = 5). Average duration of pneumonia was 4.1 months. On CT scan, pneumonic consolidations were well-marginated in 14 patients and there were cavities on initial CT scan in 16 cases. Margins of the necrotic portion on CT scan were well-demarcated in majority of the patients (16/22). Low attenuation areas on initial CT scan resulted in cavitation, fibrosis and volume loss as shown on follow-up chest radiographs. The larger the necrotic areas on CT, the more the volume loss was. CT findings of necrotizing pneumonia were well-marginated air-space consolidation with low attenuation area, with or without cavity. The extent of necrotic area was closely related with the degree of fibrotic change later on. CT is important tool for diagnosis and prediction of parenchymal damage in necrotizing pneumonia

    Full Text Available Mycoplasmal pneumoniae is the main respiratory disease in swine. The most efficient way to control it is through the use of vaccines (bacterins, whose production cost is high. The objective of this work was to develop a new alternative for controlling Swine Mycoplasmal Pneumoniae, based on a recombinant subunit vaccine containing the R1 region of P97 adhesin of Mycoplasma hyopneumoniae fused to the B subunit of the heat-labile enterotoxin of Escherichia coli (rLTB-R1. In this work we report the amplification of the genes, genetic fusion between LTB and R1 coding sequences, cloning, construction of the expression vector, as well as expression and purification of rLTB-R1 in E. coli.A Pneumonia Micoplásmica é a doença respiratória mais importante dos suínos. A forma mais eficaz de controlá-la é mediante a utilização de vacinas (bacterinas, cujo custo de produção é elevado.

    Pneumonia is a frequent condition in older people. Our aim was to examine the total healthcare cost related to pneumonia in nursing home (NH) residents over a 1-year follow-up period. This was a prospective, longitudinal, observational, and multicenter study that was a part of the Incidence of Pneumonia and related Consequences in Nursing Home Resident study. Thirteen NHs located in Languedoc Roussillon and Midi-Pyrénées regions in France were included. Resident in NH, older than 60 years and had a group iso-resource score ranging from 2 to 5. Pneumonia events were characterized according to the Observatoire du Risque Infectieux en Geriatrie criteria. Direct medical and nonmedical costs were assessed from the French health insurance perspective. Healthcare resources was retrospectively gathered from the French Social Health Insurance database and valued using the tariffs reimbursed by the French health insurance. Sociodemographic variables, clinical factors, vaccinations, cognition, depression, functional status, frailty index, as well as group iso-resource score were also recorded. Among the 800 patients initially included in the Incidence of Pneumonia and Related Consequences in Nursing Home Resident study, 345 which were listed in the database of the French Social Health Insurance were included in this economic study. Among them, 64 (18%) experienced at least 1 episode of pneumonia during the 1-year follow-up period. Mean annual total additional cost for a patient who experienced at least 1 episode of pneumonia during the 1 year follow-up period is 2813€. On average, total annual costs increased by 60% to 93% when a patient experienced at least 1 episode of pneumonia. NH-acquired pneumonia has a great impact on total cost of care for NH residents. Our results suggest the potential economic savings that could be achieved if pneumonia could be prevented in NHs. Copyright © 2017. Published by Elsevier Inc.

    Full Text Available The goal of this study was to evaluate inhaled pentamidine for the treatment of patients with mild and moderate Pneumocystis carinii pneumonitis. Eight adults with AIDS and pneumocystis pneumonia (4 with a first episode and 4 with a repeat pneumocystosis received daily inhalations of aerosol pentamidine isethionate for 21 days. Six patients were treated with doses of 300 mg of pentamidine and the remaining 2 received 600 mg every day. In the 300 mg treatment group, 2 individuals showed discrete and transient neutropenia. However, both subjects that received 600 mg of aerosol pentamidine daily developed leukopenia. One of them had major toxicity (overall severe intolerance of 12.5% that required drug discontinuation and did not allow any analysis of the treatment efficacy. Of the 7 evaluable patients, 6 (88% completed the treatment successfuly. One subject of the 300 mg regimen experienced an early recurrence. In conclusion, inhaled pentamidine is an effective treatment for mild and moderate cases of P. carinii pneumonia. It is less toxic than standard anti-pneumocystis therapy and is suitable for outpatient use.O objetivo deste estudo consistiu em avaliar pentamidina inalatória para o tratamento de pneumonia leve a moderada, causada por Pneumocystis carinii.

    Although round pneumonia is a well-known clinical entity, there have been no large case reviews, with most knowledge based on case reports and small series from the 1960s and 1970s. To review the imaging findings of a large series of children with round pneumonia. A retrospective review of radiographic and CT findings in all children reported to have round pneumonia at a large children's hospital from 2000 to 2006 was performed. Children with underlying medical conditions were excluded. Epidemiologic characteristics, radiographic and CT findings, and follow-up imaging were reviewed. The review identified 109 children (mean age 5 years, range 4 months to 19 years). Round pneumonias tended to be solitary 98% (107/109), have well-defined borders 70% (77/109), and be posteriorly located 83% (91/109), with the following lobar distribution: left lower lobe (36), right lower lobe (33), right upper lobe (28), left upper lobe (7), right middle lobe (4), and lingula (2). Round pneumonia tended to resolve on follow-up imaging (95%, 41/43) as compared to progression to lobar pneumonia (4.6%, 2/43). Three patients (2.6%, 3/112) originally suspected to have round pneumonia were later shown to have other diagnoses: cavitary necrosis in pneumonia (two) or pleural pseudocyst (one). Round pneumonia occurs in young children (mean age 5 years), tends to be a solitary lesion, and is most commonly posteriorly located. Misdiagnosis of other pathology as round pneumonia is uncommon.

    Bacterial pneumonia is commonly encountered in clinical practice. Radiology plays a prominent role in the evaluation of pneumonia. Chest radiography is the most commonly used imaging tool in pneumonias due to its availability and excellent cost benefit ratio. CT should be used in unresolved cases or when complications of pneumonia are suspected. The main applications of radiology in pneumonia are oriented to detection, characterisation and follow-up, especially regarding complications. The classical classification of pneumonias into lobar and bronchial pneumonia has been abandoned for a more clinical classification. Thus, bacterial pneumonias are typified into three main groups: Community acquired pneumonia (CAD), Aspiration pneumonia and Nosocomial pneumonia (NP).The usual pattern of CAD is that of the previously called lobar pneumonia; an air-space consolidation limited to one lobe or segment. Nevertheless, the radiographic patterns of CAD may be variable and are often related to the causative agent. Aspiration pneumonia generally involves the lower lobes with bilateral multicentric opacities. Nosocomial Pneumonia (NP) occurs in hospitalised patients. The importance of NP is related to its high mortality and, thus, the need to obtain a prompt diagnosis. The role of imaging in NP is limited but decisive. The most valuable information is when the chest radiographs are negative and rule out pneumonia. The radiographic patterns of NP are very variable, most commonly showing diffuse multifocal involvement and pleural effusion. Imaging plays also an important role in the detection and evaluation of complications of bacterial pneumonias. In many of these cases, especially in hospitalised patients, chest CT must be obtained in order to better depict these associate findings

    Hydrocarbon pneumonia is a very uncommon condition resulting from aspiration of mineral oil into the lung. We report the first description of early and sequential high-resolution computed tomographic (HRCT) findings of hydrocarbon pneumonia following attempted suicide by white spirit aspiration. Initial HRCT showed patchy opacities of coalescing masses with well-defined walls. They were visible in the middle lobe, lingula and lower lobes. Follow-up CT showed regression of the alveolar opacities, the presence of pneumatoceles and right asymptomatic pneumothorax. After 23 months of follow-up, the patient remained asymptomatic, and the follow-up CT scan was considered normal. The radiological features and a review of the relevant literature are briefly discussed. (orig.)

A talcagem via toracoscopia sob anestesia local e sedação é segura e apresenta resultados de eficácia superiores em relação ao tratamento conservador com dreno pleural no PEP, que não se resolve com a simples drenagem.Os autores deste artigo defendem que no PEP recidivante ou num primeiro episódio de PEP, em que a saída de ar seja superior a 48 horas, é necessária uma abordagem mais agressiva, de preferência a talcagem por toracoscopia. A toracoscopia permitiria simultaneamente a visualização de possíveis aderências, blebs ou bolhas.Existe um estudo que refere alterações da função pulmonar, nomeadamente a restrição e espessamento pleural, após talcagem, no PEP. Contudo, este estudo não refere o tipo e a dose de talco utilizado, a técnica de pleurodese realizada, nem o método radiológico de quantificação da pleura envolvida.Pela controvérsia existente em torno da talcagem e seus eventuais efeitos adversos, os autores deste estudo realizaram um follow-up a longo prazo (em média 118 meses, em doentes com PEP recidivante ou persistente por um período superior a 48 horas e que foram submetidos a pleurodese com talco, via tora coscopia com anestesia local e sedação.

    A patient with polycythemia vera received a moderate dose (480 mg) of busulfan intermittently over a 6 year period and later developed Hodgkin's disease. Following split-course upper mantle, chest irradiation, he developed rapidly progressive, fatal pneumonia and bone marrow hypoplasia. It is postulated that the hyperacute organ failures (lung and bone marrow) resulted from augmentation of subclinical busulfan-induced damage of these organs by additive radiation effect. It is recommended that in patients who have had antineoplastic chemotherapy, major radiotherapy to the cervicothoracic region be accompanied by careful monitoring of respiratory and hematopoietic function, both before and during radiotherapy

    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

    Purpose: To describe the initial and follow-up CT features of interstitial lung disease associated with anti-synthetase syndrome (AS-ILD). Materials and methods: Two independent thoracic radiologists retrospectively analysed thin-section CT images obtained at diagnosis of AS-ILD in 33 patients (17 positive for anti-Jo1, 13 for anti-PL12, and three for anti-PL7 antibodies). They evaluated the pattern, distribution and extent of the CT abnormalities. They also evaluated the change in findings during follow-up (median 27 months; range 13–167 months) in 26 patients. Results: At diagnosis, ground-glass opacities (100%), reticulations (87%) and traction bronchiectasis (76%) were the most common CT findings. Consolidations were present in 45% of patients. A non-specific interstitial pneumonia (NSIP), organizing pneumonia (OP) or mixed NSIP-OP CT pattern were observed in 15 out of 33 (45%), seven out of 33 (21%) and eight out of 33 (24%) patients, respectively, whereas the CT pattern was indeterminate in three patients. During follow-up, consolidations decreased or disappeared in 11 out of 12 patients (92%), among which seven within the first 6 months, but honeycombing progressed or appeared in ten out of 26 patients (38%) and overall disease extent increased in nine out of 26 patients (35%). Conclusion: CT features at diagnosis of AS-ILD mainly suggest NSIP and OP, isolated or in combination. Consolidations decrease or disappear in most cases but the disease may progress to fibrosis in more than one third of patients.

    Full Text Available Invasive mechanical ventilation (IMV represents a risk factor for the development of ventilator-associated pneumonia (VAP, which develops at least 48 h after admission in patients ventilated through tracheostomy or endotracheal intubation. VAP is the most frequent intensive-care-unit (ICU-acquired infection among patients receiving IMV. It contributes to an increase in hospital mortality, duration of MV and ICU and length of hospital stay. Therefore, it worsens the condition of the critical patient and increases the total cost of hospitalization. The introduction of preventive measures has become imperative, to ensure control and to reduce the incidence of VAP. Preventive measures focus on modifiable risk factors, mediated by non-pharmacological and pharmacological evidence based strategies recommended by guidelines. These measures are intended to reduce the risk associated with endotracheal intubation and to prevent microaspiration of pathogens to the lower airways. Resumo: A ventilação mecânica invasiva representa um fator de risco para o desenvolvimento da pneumonia associada ao ventilador (PAV, que se desenvolve 48 horas ou mais após a admissão hospitalar, em doentes ventilados através de traqueostomia ou intubação endotraqueal. A PAV é a infeção adquirida na unidade de cuidados intensivos (UCI mais frequente entre os doentes submetidos a ventilação mecânica invasiva. Contribui para o aumento da mortalidade hospitalar, da duração da ventilação mecânica e do tempo de internamento na UCI e no hospital. Por conseguinte, agrava o estado de saúde do doente crítico e aumenta o custo total da hospitalização. A adoção de medidas preventivas é imprescindível, de modo a garantir o controlo e a diminuição da incidência da PAV. As medidas preventivas incidem sobre os fatores de risco modificáveis, sendo aplicadas estratégias não farmacológicas e farmacológicas baseadas na evidência e recomendadas por guidelines. As

    Full Text Available JUSTIFICATIVA E OBJETIVOS: Os pacientes criticamente enfermos representam uma população com múltiplos fatores de risco para aspiração. Associa-se a essa complicação a redução do estado de consciência, ventilação mecânica e comorbidades como o acidente vascular encefálico (AVE, freqüentemente presente nos pacientes internados em unidade de terapia intensiva (UTI. A identificação das alterações da deglutição pode auxiliar na detecção de pacientes com alto risco de aspiração, prevenindo complicações pulmonares como a pneumonia aspirativa. O objetivo deste relato foi mostrar um caso de broncopneumonia aspirativa recorrente grave, após acidente vascular encefálico agudo e intubação traqueal, alertando para a necessidade do diagnóstico e do tratamento adequados nestes pacientes. RELATO DO CASO: Paciente do sexo masculino, 57 anos internado no hospital por AVE, evoluiu após 10 dias de internação com quadr o de pneumonia aspirativa, necessitando de intubação traqueal e transferência para a UTI. Permaneceu intubado por quatro dias, e logo após a extubação evoluiu com progressivo infiltrado pulmonar relacionado a novos episódios de aspiração. A avaliação fonoaudiológica na UTI classificou o paciente como portador de disfagia orofaríngea grave, com risco para penetração e aspiração laringotraqueal. Recebeu alta da UTI após 13 dias, porém na enfermaria evoluiu com novo quadro aspirativo após oito dias, necessitando de re-internação na UTI e prolongada internação hospitalar. CONCLUSÕES: Os pacientes internados em UTI devem ter seu risco para alterações de deglutição e de aspiração identificado para que medidas preventivas possam ser instituídas, evitando-se a morbidade e a mortalidade associada à aspiração.BACKGROUND AND OBJECTIVES: Critically ill patients represent a population with multiple risk factors for aspiration.

    Characterization and follow-up evaluation of chest CT of RSV pneumonia in immune-compromised adults during a seasonal epidemic. Retrospective analysis of 132 chest CT examinations of 51 adult immune-compromised patients (29 m/22f, diameter 58 years) with clinical signs of pneumonia and positive RSV test in winter 2011/2012. Two experienced chest radiologists evaluated the morphology (bronchial wall thickening, tree-in-bud, nodules, halo, ground-glass opacities, consolidations, pleural fluid) of the CT scans by consensus. Pathological findings were in 86 % of the chest CT scans: Areas of ground-glass attenuation in 64 %, consolidations in 56 %, nodules in 55 % (diameter 8 mm in maximal diameter, with halo in 71 %), pleural fluid in 44 % (diameter 2 cm), tree-in-bud in 36 %, bronchial wall thickening in 27 % and more than one morphological finding in 72 %. There were no pathological CT findings in 14 % of patients with clinical symptoms of pneumonia because these patients did not undergo follow-up. Radiological progression was found in 45 % of patients and regression in 33 % in follow-up examinations. In 37 % an additional examination of the paranasal sinuses was performed and showed sinusitis in 63 % of cases. 90 % of the patients had sinusitis as well as pneumonia. In addition to RSV, a further pathogenic agent was found in bronchoalveolar lavage of five patients (Aspergillus spec., herpes simplex virus, Pseudomonas aeruginosa). The most characteristic signs in chest CT scans were at the beginning of pneumonia with nodules and tree-in-bud often combined with bronchial wall thickening. The following CT scans showed characteristic but not pathognomonic chest CT findings of RSV pneumonia. These morphological findings should be recognized seasonally (winter) especially at the beginning of the case of pneumonia. RSV-associated additional sinusitis is probably common and should be noticed.

    Chlamydophila pneumoniae and Mycoplasma pneumoniae are associated with acute exacerbation of bronchial asthma (AEBA). The aim of this study was to evaluate the correlation between these acute bacterial infections and the severity of AEBA. We prospectively analysed consecutive patients admitted to the Emergency Department with acute asthma exacerbation. In every patient peak expiratory flow (PEF) measurement was performed on admission, and spirometry during follow-up. Serology for Chlamydophila and Mycoplasma pneumoniae was performed on admission and after 4-8 weeks. Fifty-eight patients completed the study. Acute atypical infections (AAI) was observed in 22/58 cases; we found single acute C. pneumoniae in 19 cases, single acute M. pneumoniae in 2 cases, and double acute infection in one case. Functional impairment on admission was greater in patients with AAI than in patients without AAI (PEF 205 +/- 104 L/min vs 276 +/- 117 p = 0.02) and persisted until visit 2 (FEV1% 76.30 +/- 24.54 vs FEV1% 92.91 +/- 13.89, p = 0.002). Moreover, the proportion of patients who presented with severe AEBA was significantly greater in the group with AAI than in the group without AAI (15/22 vs 12/36, p = 0.01; OR 4.29, 95% CI 1.38-13.32). Our data suggest an association between acute atypical infection and a more severe AEBA.

    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 OBJECTIVE: To investigate the possible relationship between atherothrombotic stroke and Chlamydia pneumoniae. METHOD: 150 patients with carotid atherothrombosis were enrolled. The casuistic was divided in three groups: ischemic stroke (IS: 65 patients; transient ischemic attack (TIA: 26 patients; and control: 59. The IS or TIA onset was up to 30 days from the beginning of the study. Carotid atheromatoses was diagnosed by Doppler-ultrasonography. Patients with cardioembolic risk or non-atherothrombotic origin were excluded. Comparisons were done between the three groups, and within each group according to the different age sub-groups, to the main arteries affected, and to the atherogenic risk factors. Bacteria detection was done using polimerase chain reaction. RESULTS: Only one patient tested positive for C. pneumoniae belonging to the control group. CONCLUSION: These results do not suggest that C. pneumoniae participated in the onset of IS or TIA or that it has a role in carotid plaque destabilization.OBJETIVO: Investigar a possível relação entre Chlamydia pneumoniae e acidente vascular cerebral aterotrombótico (AVC.

    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.

    To determine the long-term prognosis of children with vocal fold mobility impairment (VFMI) after cardiac surgery, with respect to time to normal feeding and incidence of admissions for pneumonia and feeding difficulties. A retrospective chart review was conducted of all neonates who had otolaryngology exam after cardiac surgery at a tertiary children's hospital from May 2007 to May 2008. Charts were reviewed for demographics, type of cardiac surgery, vocal fold mobility, diet at time of discharge and at last follow-up, time to full oral feeding, and hospital admissions. There were a total of 94 patients included in the study, 17 of whom had VFMI. While significantly more patients with VFMI required modified diet at discharge, 48% compared to 19% of patients with normal vocal fold mobility; there was no statistically significant difference in time to regular diet on long-term follow-up, 0.8 years (VFMI) compared to 0.4 years (normal vocal fold mobility). Of the 25 patients with modified diet or gastrostomy tube at discharge, 52% returned to full feeds within a year. There was no difference in hospitalizations for pneumonia in patients with or without VFMI. However in patients with VFMI, 35% required readmission for feeding difficulty or poor weight gain compared to only 5% in the infants with normal vocal fold mobility. After neonatal cardiac surgery, there do not appear to be long-term effects of VFMI with regards to readmission for pneumonia. However, there is an increased risk for hospitalization with respect to feeding difficulties in those neonates with VFMI. The overall prognosis for time to oral feeding is good. Copyright © 2016.

    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 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.

    Full Text Available Abstract Background Allogeneic red blood cell transfusion is frequently used in total hip replacement surgery (THR. However, data on the prognosis of transfused patients are sparse. In this study we compared the risk of complications following THR in transfused and non-transfused patients. Methods A population-based follow-up study was performed using data from medical databases in Denmark. We identified 28,087 primary THR procedures performed from 1999 to 2007, from which we computed a propensity score for red blood cell transfusion based on detailed data on patient-, procedure-, and hospital-related characteristics. We were able to match 2,254 transfused with 2,254 non-transfused THR patients using the propensity score. Results Of the 28,087 THR patients, 9,063 (32.3% received at least one red blood cell transfusion within 8 days of surgery. Transfused patients had higher 90-day mortality compared with matched non-transfused patients: the adjusted OR was 2.2 (95% confidence interval (CI: 1.2-3.8. Blood transfusion was also associated with increased odds of pneumonia (OR 2.1; CI: 1.2-3.8, whereas the associations with cardiovascular or cerebrovascular events (OR 1.4; CI: 0.9-2.2 and venous thromboembolism (OR 1.2; CI: 0.7-2.1 did not reach statistical significance. The adjusted OR of reoperation due to infection was 0.6 (CI: 0.1-2.9. Conclusions Red blood cell transfusion was associated with an adverse prognosis following primary THR, in particular with increased odds of death and pneumonia. Although the odds estimates may partly reflect unmeasured bias due to blood loss, they indicate the need for careful assessment of the risk versus benefit of transfusion even in relation to routine THR procedures.

    Clinical features and investigations lack predictive value when diagnosing pneumonia, especially when patients are ventilated and when patients develop ventilator associated pneumonia (VAP). New tools to aid diagnosis are important to improve outcomes. This pilot study examines the potential for metabolic profiling to aid the diagnosis in critical care. In this prospective observational study ventilated patients with brain injuries or pneumonia were recruited in the intensive care unit and serum samples were collected soon after the start of ventilation. Metabolic profiles were produced using 1D 1 H NMR spectra. Metabolic data were compared using multivariate statistical techniques including Principal Component Analysis (PCA) and Orthogonal Partial Least Squares Discriminant Analysis (OPLS-DA). We recruited 15 patients with pneumonia and 26 with brain injuries, seven of whom went on to develop VAP. Comparison of metabolic profiles using OPLS-DA differentiated those with pneumonia from those with brain injuries (R 2 Y=0.91, Q 2 Y=0.28, p=0.02) and those with VAP from those without (R 2 Y=0.94, Q 2 Y=0.27, p=0.05). Metabolites that differentiated patients with pneumonia included lipid species, amino acids and glycoproteins. Metabolic profiling shows promise to aid in the diagnosis of pneumonia in ventilated patients and may allow a more timely diagnosis and better use of antibiotics. Copyright © 2017 The Authors.

    Full Text Available Probably the most important decision in the management of Community-Acquired Pneumonia (CAP is patient site of care. Patients with Streptococcus pneumoniae-caused CAP admitted to our hospital between 1st January and 31st December 2006 were retrospectively analysed. Samples of blood, sputum, bronchial and bronchoalveolar lavage and urine were collected for microbiological testing using standard culture techniques and urine antigen detection. Pneumonia Severity Index (PSI and British Thoracic Society (BTS CURB-65 scoring tools were evaluated. The statistical treatment was performed using the SPSS 14.0 program. We included 104 patients, 67.3% male, median age 63 years old, mortality 13.4%. There was a significant association between the PSI and CURB-65 score and mortality. Despite advances, CAP is still an important health problem with a high atten - dant morbi-mortality. This study confirms the value of PSI and CURB-65 in the prediction of severe pneumonia.

    Full Text Available BACKGROUND: Pneumonia remains the leading cause of death in young children globally and improved diagnostics are needed to better identify cases and reduce case fatality. Metabolomics, a rapidly evolving field aimed at characterizing metabolites in biofluids, has the potential to improve diagnostics in a range of diseases. The objective of this pilot study is to apply metabolomic analysis to childhood pneumonia to explore its potential to improve pneumonia diagnosis in a high-burden setting. METHODOLOGY/PRINCIPAL FINDINGS: Eleven children with World Health Organization (WHO-defined severe pneumonia of non-homogeneous aetiology were selected in The Gambia, West Africa, along with community controls. Metabolomic analysis of matched plasma and urine samples was undertaken using Ultra Performance Liquid Chromatography (UPLC coupled to Time-of-Flight Mass Spectrometry (TOFMS. Biomarker extraction was done using SIMCA-P+ and Random Forests (RF. 'Unsupervised' (blinded data were analyzed by Principal Component Analysis (PCA, while 'supervised' (unblinded analysis was by Partial Least Squares-Discriminant Analysis (PLS-DA and Orthogonal Projection to Latent Structures (OPLS. Potential markers were extracted from S-plots constructed following analysis with OPLS, and markers were chosen based on their contribution to the variation and correlation within the data set. The dataset was additionally analyzed with the machine-learning algorithm RF in order to address issues of model overfitting and markers were selected based on their variable importance ranking. Unsupervised PCA analysis revealed good separation of pneumonia and control groups, with even clearer separation of the groups with PLS-DA and OPLS analysis. Statistically significant differences (p<0.05 between groups were seen with the following metabolites: uric acid, hypoxanthine and glutamic acid were higher in plasma from cases, while L-tryptophan and adenosine-5'-diphosphate (ADP were lower

    Although preservation of the spleen following abdominal trauma and spleen-preserving surgical procedures have become gold standards, about 22,000 splenectomies are still conducted annually in the USA. Infections, mostly by encapsulated organisms, are the most well-known complications following splenectomy. Recently, thrombosis and cancer have become recognized as potential adverse outcomes post-splenectomy. Among more than 4 million hospitalized USA veterans, we assessed incidence and mortality due to infections, thromboembolism, and cancer including 8,149 cancer-free veterans who underwent splenectomy with a follow-up of up to 27 years. Relative risk estimates and 95% confidence intervals were calculated using time-dependent Poisson regression methods for cohort data. Splenectomized patients had an increased risk of being hospitalized for pneumonia, meningitis, and septicemia (rate ratios=1.9–3.4); deep venous thrombosis and pulmonary embolism (rate ratios=2.2); certain solid tumors: buccal, esophagus, liver, colon, pancreas, lung, and prostate (rate ratios =1.3–1.9); and hematologic malignancies: non-Hodgkin lymphoma, Hodgkin lymphoma, multiple myeloma, acute myeloid leukemia, chronic lymphocytic leukemia, chronic myeloid leukemia, and any leukemia (rate ratios =1.8–6.0). They also had an increased risk of death due to pneumonia and septicemia (rate ratios =1.6–3.0); pulmonary embolism and coronary artery disease (rate ratios =1.4–4.5); any cancer: liver, pancreas, and lung cancer, non-Hodgkin lymphoma, Hodgkin lymphoma, and any leukemia (rate ratios =1.3–4.7). Many of the observed risks were increased more than 10 years after splenectomy. Our results underscore the importance of vaccination, surveillance, and thromboprophylaxis after splenectomy.

    The sustained health-related quality-of-life of patients surviving community-acquired pneumonia has not been accurately quantified. The aim of the current study was to quantify differences in health-related quality-of-life of community-dwelling elderly with and without community-acquired pneumonia during a 12-month follow-up period. In a matched cohort study design, nested in a prospective randomized double-blind placebo-controlled trial on the efficacy of the 13-valent pneumococcal vaccine in community-dwelling persons of ≥65 years, health-related quality-of-life was assessed in 562 subjects hospitalized with suspected community-acquired pneumonia (i.e. diseased cohort) and 1145 unaffected persons (i.e. non-diseased cohort) matched to pneumonia cases on age, sex, and health status (EQ-5D-3L-index). Health-related quality-of-life was determined 1-2 weeks after hospital discharge/inclusion and 1, 6 and 12 months thereafter, using Euroqol EQ-5D-3L and Short Form-36 Health survey questionnaires. One-year quality-adjusted life years (QALY) were estimated for both diseased and non-diseased cohorts. Separate analyses were performed for pneumonia cases with and without radiologically confirmed community-acquired pneumonia. The one-year excess QALY loss attributed to community-acquired pneumonia was 0.13. Mortality in the post-discharge follow-up year was 8.4% in community-acquired pneumonia patients and 1.2% in non-diseased persons (p pneumonia patients, compared to non-diseased persons, but differences in health-related quality-of-life between radiologically confirmed and non-confirmed community-acquired pneumonia cases were not statistically significant. Community-acquired pneumonia was associated with a six-fold increased mortality and 16% lower quality-of-life in the post-discharge year among patients surviving hospitalization for community-acquired pneumonia, compared to non-diseased persons.

    The aim of this study was to evaluate the medium-term outcome (health status, medical and surgical French National Health Authority-recommended follow-up, and quality of life) of children born with type III esophageal atresia (EA). Previous events (during the perinatal period, associated abnormalities, respiratory and digestive complications) of children treated for type III EA at the Marseille university hospitals between 1999 and 2009 were noted. Parents completed a standardized questionnaire concerning the health of their children during the previous year, and a quality-of-life questionnaire (PedsQL 4.0) was also completed by children aged more than 8 years. Among the 68 children treated, 44 responded to our solicitation (mean age, 7.6 years; range, 3-12.8 years). Previous important events were : pneumonia(s) (65%), asthma before the age of 3 years (66%), hospitalization for a respiratory event (45%), fundoplication (20%), and esophageal dilatation (45%). We noted current chronic cough (16%), asthma (30%), dysphagia (39%), and symptomatic gastroesophageal reflux (9%). National guidelines were not respected, except for the surgical indications in children aged less than 6 years. The quality-of-life scores (n=43 children) were similar to healthy controls but were negatively influenced by a gastrostomy procedure (P=0.020), pneumonia (P=0.013), and hospitalization due to a respiratory event (P=0.006) or a digestive event (P=0.010), and also by current asthma (P=0.004). In conclusion, despite recurrent respiratory or digestive symptoms and inadequate recommended follow-up, the quality of life of children treated for type III of EA is good. Copyright © 2013.

    Full Text Available BACKGROUND: Post-discharge mortality among children with severe illness in resource-limited settings is under-recognized and there are limited data. We evaluated post-discharge mortality in a recently reported cohort of children with severe malnutrition and pneumonia, and identified characteristics associated with an increased risk of death. METHODS: Young children (<5 years of age with severe malnutrition (WHO criteria and radiographic pneumonia on admission to Dhaka Hospital of icddr,b over a 15-month period were managed according to standard protocols. Those discharged were followed-up and survival status at 12 weeks post-discharge was determined. Verbal autopsy was requested from families of those that died. RESULTS: Of 405 children hospitalized with severe malnutrition and pneumonia, 369 (median age, 10 months were discharged alive with a follow-up plan. Of these, 32 (8.7% died in the community within 3 months of discharge: median 22 (IQR 9-35 days from discharge to death. Most deaths were reportedly associated with acute onset of new respiratory or gastrointestinal symptoms. Those that died following discharge were significantly younger (median 6 [IQR 3,12] months and more severely malnourished, on admission and on discharge, than those that survived. Bivariate analysis found that severe wasting on admission (OR 3.64, 95% CI 1.66-7.97 and age <12 months (OR 2.54, 95% CI 1.1-8.8 were significantly associated with post-discharge death. Of those that died in the community, none had attended a scheduled follow-up and care-seeking from a traditional healer was more common (p<0.001 compared to those who survived. CONCLUSION AND SIGNIFICANCE: Post-discharge mortality was common in Bangladeshi children following inpatient care for severe malnutrition and pneumonia. The underlying contributing factors require a better understanding to inform the potential of interventions that could improve survival.

    Asthma is thought to be a Th2 disease while sarcoidosis is considered a Th1 granulomatous disorder. Organising pneumonia is a histologic pattern of lung injury. When it has no recognisable cause it is defined as cryptogenic organising pneumonia. We herein report the case of a patient with recurrent and steroid sensitive organising pneumonia associated with chronic sarcoidosis in an atopic, moderate persistent asthmatic patient. Each disease has been documented with transbronchial biopsies and recurrence of organising pneumonia was suggested by clinical features and by follow up HRCT which shows distinctive signs even in associated disease. Steroids are the mainstay of therapy for these disorders and especially for the consolidated processes typical of organising pneumonia but prognostic indices for relapse and progression are lacking.

    CT scans in 11 cases of chronic eosinophilic pneumonia (CEP) were reviewed. Peripheral dense opacities suggesting air-space consolidation were the most peculiar findings seen in 9 patients on CT, but 7 on chest radiographs. Five patients showed broad plate-like opacities parallel to the pleura, which were the results of resolution from the periphery of the consolidation. Diffuse interstitial opacities suggesting alveolitis were the predominant finding in 3 patients, one of which also had peripheral air-space consolidation. Follow-up CT showed no residual abnormality except one who had DIP concomitant with CEP. CT scans are useful tool for both diagnosis and follow-up of CEP. (author)

    in 34 patients with idiopathic dilated cardiomyopathy submitted to this procedure from May 1988 to September 1994. Twenty seven patients were in New York Heart Association functional class III and 7 were in class IV before the operation, despite the use of maximal medical therapy. Hospital mortality was 2.9% and 1 patient presenting heart failure progression was submitted to urgent heart transplantation 42 days after cardiomyoplasty. The other patients were followed-up from 2 to 73 months (mean, 27.4 months. At 6 months of follow-up, 12 patients were in functional class 1,15 patients in class II and 3 patients in class III (p=0.001, in relation to preoperative data. Similar findings were observed from one to four years of follow-up. On the other hand, 14 patients died up to 5 years after the operation and the survival rates were 84.7% at 1 year, 67.7% at 2 years and 39.9% at 5 years of follow-up. The cause of death was progression of heart failure in 9 patients and 5 patients died suddenly. By stepwise Cox regression method, patients operated in functional class IV had relative risk of death 5.5 times higher than class III patients (p=0.006, whose survival rate was 52.7% at 5 years of followup. Regarding cardiomyoplasty influence on ventricular function, radioisotopic left ventricular (LV ejection fraction improved from 19.8 + 3.1% to 23.6 + 6.2%, at 6 months of follow-up. Doppler-echocardiography documented similar changes in LV wall shortening. Also, right heart catheterization showed significant increases in mean arterial pressure, stroke index and LV stroke work index, which were associated with the decrease of mean pulmonary wedge pressure. On the other hand, it was not found any significant postoperative change in ventricular arrhythmia and atrial fibrillation incidence. At the late postoperative period, the hemodynamic improvement was maintained up to 5 years of follow-up, while LV ejection fraction and wall shortening tended to decrease after the second

    Previous investigations in adult smokers from the COPDGene Study have shown that early-life respiratory disease is associated with reduced lung function, COPD, and airway thickening. Using 5-year follow-up data, we assessed disease progression in subjects who had experienced early-life respiratory disease. We hypothesized that there are alternative pathways to reaching reduced FEV 1 and that subjects who had childhood pneumonia, childhood asthma, or asthma-COPD overlap (ACO) would have less lung function decline than subjects without these conditions. Subjects returning for 5-year follow-up were assessed. Childhood pneumonia was defined by self-reported pneumonia at < 16 years. Childhood asthma was defined as self-reported asthma diagnosed by a health professional at < 16 years. ACO was defined as subjects with COPD who self-reported asthma diagnosed by a health-professional at ≤ 40 years. Smokers with and those without these early-life respiratory diseases were compared on measures of disease progression. Follow-up data from 4,915 subjects were examined, including 407 subjects who had childhood pneumonia, 323 subjects who had childhood asthma, and 242 subjects with ACO. History of childhood asthma or ACO was associated with an increased exacerbation frequency (childhood asthma, P < .001; ACO, P = .006) and odds of severe exacerbations (childhood asthma, OR, 1.41; ACO, OR, 1.42). History of childhood pneumonia was associated with increased exacerbations in subjects with COPD (absolute difference [β], 0.17; P = .04). None of these early-life respiratory diseases were associated with an increased rate of lung function decline or progression on CT scans. Subjects who had early-life asthma are at increased risk of developing COPD and of having more active disease with more frequent and severe respiratory exacerbations without an increased rate of lung function decline over a 5-year period.

  17. Cicatricial organising pneumonia mimicking a fibrosing interstitial pneumonia.

    Churg, Andrew; Wright, Joanne L; Bilawich, AnaMaria

    2018-04-01

    Organising pneumonia (OP) is composed of loose granulation tissue plugs in distal airspaces; these disappear with steroid treatment. Recently a variant labelled 'cicatricial' OP has been described in which the granulation tissue organised to much denser fibrous tissue but still retained the usual pattern of OP. Here we report 10 patients thought to have an interstitial lung disease, and who on biopsy had a variant of cicatricial OP characterised by linear bands or small nodular masses of dense fibrous tissue that does not resemble ordinary OP. The bands/nodules were usually distributed randomly but occasionally resembled fibrotic non-specific interstitial pneumonia in local areas. Small foci of loose granulation tissue at the edge of the fibrotic bands sometimes mimicked fibroblast foci. Recognisable conventional OP was always present, but often in very small amounts. Four cases, including one patient with Ehlers-Danlos syndrome, showed formation of bone in the fibrotic bands and nodules. On computerised tomography (CT) scan of the chest some cases looked like typical OP, but some demonstrated only irregularly distributed linear opacities, sometimes with associated calcification. Follow-up imaging on six cases showed that the process either markedly improved or remained stable over time; no case had progressive disease. Cicatricial OP with this pathological pattern represents an uncommon form of OP that appears to be a generally benign process which may have persisting linear opacities on CT scan but that does not progress; however, it can be confused on biopsy and CT with a fibrosing interstitial pneumonia. © 2017 John Wiley & Sons Ltd.

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

    Mycoplasma pneumoniae (MP) is a leading cause of community-acquired pneumonia in children and young adults. Although MP pneumonia is usually benign and self-limited, in some cases it can develop into life-threating refractory MP pneumonia (RMPP). However, the pathogenesis of RMPP is poorly understood. The identification and characterization of proteins related to RMPP could provide a proof of principle to facilitate appropriate diagnostic and therapeutic strategies for treating paients with MP. In this study, we used a quantitative proteomic technique (iTRAQ) to analyze MP-related proteins in serum samples from 5 patients with RMPP, 5 patients with non-refractory MP pneumonia (NRMPP), and 5 healthy children. Functional classification, sub-cellular localization, and protein interaction network analysis were carried out based on protein annotation through evolutionary relationship (PANTHER) and Cytoscape analysis. A total of 260 differentially expressed proteins were identified in the RMPP and NRMPP groups. Compared to the control group, the NRMPP and RMPP groups showed 134 (70 up-regulated and 64 down-regulated) and 126 (63 up-regulated and 63 down-regulated) differentially expressed proteins, respectively. The complex functional classification and protein interaction network of the identified proteins reflected the complex pathogenesis of RMPP. Our study provides the first comprehensive proteome map of RMPP-related proteins from MP pneumonia. These profiles may be useful as part of a diagnostic panel, and the identified proteins provide new insights into the pathological mechanisms underlying RMPP.

    The classic auscultation with stethoscope is the established clinical method for the detection of lung diseases. The interpretation of the sounds depends on the experience of the investigating physician. Therefore, a new computer-based method has been developed to classify breath sounds from digital lung sound recordings. Lung sounds of 11 patients with one-sided pneumonia and bronchial breathing were recorded on both the pneumonia side and on contralateral healthy side simultaneously using two microphones. The spectral power for the 300-600 Hz frequency band was computed for four respiratory cycles and normalized. For each breath, the ratio R between the time-segments (duration = 0.1 s) with the highest inspiratory and highest expiratory flow was calculated and averaged. We found significant differences in R between the pneumonia side (R = 1.4 +/- 1.3) and the healthy side (R = 0.5 +/- 0.5; p = 0.003 Wilcoxon-test) of lung. In 218 healthy volunteers we found R = 0.3 +/- 0.2 as a reference-value. The differences of ratio R (delta R) between the pneumonia side and the healthy side (delta R = 1.0 +/- 0.9) were significantly higher compared to follow-up studies after recovery (delta R = 0.0 +/- 0.1, p = 0.005 Wilcoxon-test). The computer based detection of bronchial breathing can be considered useful as part of a quantitative monitoring of patients at risk to develop pneumonia.

The first two are characterised by proponent monitoring and evaluation of individual impacts and indicators while the latter takes a holistic view based around focused sustainability criteria relevant to the context. The implications of three sustainability challenges on follow-up are also examined: contested time horizons and value changes, trade-offs, and interdisciplinarity. We conclude that in order to meet these challenges some form of adaptive follow-up is necessary and that the contribution to sustainability approach is the best approach. -- Highlights: • We explore sustainability follow-up for three different sustainability models. • Long-time frames require adaptive follow-up and are a key follow-up challenge. • Other key challenges include interdisciplinarity, and trade-offs. • Sustainability follow-up should be a direction of travel and not an outcome. • Only the follow-up for contribution to sustainability model addresses sustainability challenges sufficiently.

    In Xuanwei County, China, unvented indoor coal burning is strongly associated with increased risk of lung cancer and chronic obstructive pulmonary disease. However, the impact of coal burning and stove improvement on risk of pneumonia is not clear. We conducted a retrospective cohort study among all farmers born 1917 through 1951 and living in Xuanwei as of 1 January 1976. The analysis included a total of 42,422 cohort members. Follow-up identified all deaths in the cohort from 1976 through 1996. Ages at entry into and at exit from follow-up ranged from 24 to 59 years and from 25 to 80 years, respectively. The record search detected 225 deaths from pneumonia, and 32,332 (76%) were alive as of 31 December 1996. We constructed multivariable Cox models (time variable = age) to estimate hazard ratios (HRs) and 95% confidence intervals (CIs). Use of coal, especially smokeless coal, was positively associated with pneumonia mortality. Annual tonnage and lifetime duration of smoky and smokeless coal use were positively associated with pneumonia mortality. Stove improvement was associated with a 50% reduction in pneumonia deaths (smoky coal users: HR, 0.521; 95% CI, 0.340-0.798; smokeless coal users: HR, 0.449; 95% CI, 0.215-0.937). Our analysis is the first to suggest that indoor air pollution from unvented coal burning is an important risk factor for pneumonia death in adults and that improving ventilation by installing a chimney is an effective measure to decrease it.

    Chronic eosinophilic pneumonia is a rare idiopathic interstitial lung disease. The nearly pathognomonic radiographic finding is the peripheral distribution of alveolar opacities. Pleural effusions are rarely seen. We report a case of chronic eosinophilic pneumonia with transudative eosinophilic pleural effusion. A 57-year-old Hispanic woman, a nonsmoker with a history of controlled asthma, presented to the hospital with unresolving pneumonia despite three rounds of antibiotics over a 2-month period. She was later diagnosed with chronic eosinophilic pneumonia based on the presence of peripheral blood eosinophilia, the peripheral distribution of alveolar infiltrates on chest radiograph, and a lung parenchymal biopsy with infiltrates of eosinophils. Upon presentation, our patient had a right-sided moderate-sized pleural effusion. The pleural fluid profile was consistent with a transudative effusion with eosinophil predominance. Our patient responded promptly to oral corticosteroid treatment in a few days. The pulmonary infiltrates and pleural effusion subsided on a 1-month follow-up chest radiograph after starting corticosteroid treatment. We report the first case of chronic eosinophilic pneumonia presenting with pneumonia with ipsilateral transudative eosinophilic pleural effusion. Like other cases of chronic eosinophilic pneumonia, early recognition and diagnosis is essential and prompt treatment with corticosteroids is the mainstay of therapy. Pleural effusion resolved without the further need for therapeutic thoracentesis.

    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)

    Objective. To determine the outcome of areas of ground-glass attenuation and assess disease progression on serial high-resolution CT (HRCT) scans of patients with biopsy specimen-proved usual interstitial pneumonia (UIP) and desquamative interstitial pneumonia (DIP). Materials and methods. Twelve patients with biopsy specimen-proved UIP and 11 patients with biopsy specimen-proved DIP who had initial and follow-up HRCT scans (median interval, 10 months) were reviewed. Eleven patients with UIP and 11 with DIP received treatment between the initial and follow-up CT scans. The scans were evaluated for the presence and extent of ground-glass attenuation, irregular linear opacities and honeycombing, and overall extent of parenchymal involvement. Results. On initial CT scans, all 12 patients with UIP had areas of ground-glass attenuation (mean±SD extent, 30±16%) and irregular lines (mean±SD extent, 17±7%) and 10 patients had honeycombing (mean±SD extent, 10±6%). All 11 patients with DIP had areas of ground-glass attenuation on initial HRCT scans (mean±SD extent, 51±26%), 5 patients had irregular linear opacities (mean±SD extent, 5±5%), and 1 patient had honeycombing. Nine of the 12 patients with UIP showed increase in the extent of ground-glass attenuation (n=6) or progression to irregular lines (n=2) or honeycombing (n=4) on follow-up as compared with only 2 patients with DIP who showed progression to irregular lines (n=1) or honeycombing (n=1) (p 2 test). Conclusion. In patients with UIP, areas of ground-glass attenuation usually increase in extent or progress to fibrosis despite treatment. Areas of ground-glass attenuation in most patients with DIP remain stable or improve with treatment. (authors)

    Idiopathic interstitial pneumonias (IIP) comprise seven entities with distinct histologic patterns. In their idiopathic form IIP are rare diseases. They are, nevertheless, considered prototypes of the much more common secondary interstitial pneumonias. The advent of high-resolution computed tomography (HRCT) has had a profound impact on the imaging of IIP, because the detailed delineation of the lung anatomy allows a close correlation between the histologic patterns of IIP and the CT features. On the basis of CT morphology and in the correct clinical context, the radiologist can achieve an accurate diagnosis in many cases. However, due to overlap between the various entities, complementary lung biopsy is recommended in virtually all cases. This article reviews the CT pattern of IIP and offers relevant clinical and histological information for the purpose of enabling the radiologist to understand and participate in the multidisciplinary concept of IIP.

    Recent studies suggest older patients hospitalized for community-acquired pneumonia are at risk for new-onset cognitive impairment. The characteristics of long-term cognitive impairment after pneumonia, however, have not been elucidated. To characterize long-term cognitive impairment among adults of all ages hospitalized for community-acquired pneumonia. Prospective cohort study. Adults without severe preexisting cognitive impairment who were hospitalized with community-acquired pneumonia. At enrollment, we estimated baseline cognitive function with the Short Informant Questionnaire on Cognitive Decline in the Elderly (IQCODE). At 2- and 12-month follow-up, we assessed cognition using the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) and tests of executive function, diagnosing cognitive impairment when results were ≥ 1.5 standard deviations below published age-adjusted means for the general population. We also identified subtypes of mild cognitive impairment using standard definitions. We assessed 58 (73%) of 80 patients who survived to 2-month follow-up and 57 (77%) of 74 who survived to 12-month follow-up. The median [range] age of survivors tested was 57 [19-97] years. Only 8 (12%) had evidence of mild cognitive impairment at baseline according to the Short IQCODE, but 21 (38%) at 2 months and 17 (30%) at 12 months had mild cognitive impairment per the RBANS. Moderate-to-severe cognitive impairment was common among adults ≥ 65 years [4/13 (31%) and 5/13 (38%) at 2 and 12 months, respectively] but also affected many of those cognitive domains affected one-third of patients ≥ 65 years old and 20% of younger patients, and another third of survivors had mild cognitive impairment.

    To determine if the presence of pneumonia and pressure ulcers are associated in individuals with an acute spinal cord injury during acute care and rehabilitation hospitalizations. Retrospective, secondary analyses of data obtained from the Spinal Cord Injury Model Systems enrolled from 1993 until 2006 Setting: Acute care hospitalization and inpatient rehabilitation facilities Participants: A cohort of individuals hospitalized in acute care (n = 3,098) and inpatient rehabilitation (n = 1,768) was included in the analysis. Frequencies of pressure ulcer formation and episodes of pneumonia were noted in both settings. Not applicable. Pressure ulcer formation and diagnosis of pneumonia Results: The development of pressure ulcers, including stage I, was 20.3% acute care and 21.1% during in inpatient rehabilitation. Multivariate logistic regression analyses revealed a significant association of pneumonia with occurrence of pressure ulcers (P ≤ 0.001, OR = 2.3 and 2.2 respectively), the American Spinal Injury Association Impairment Scale grades (P pneumonia, after adjusting for injury severity, age, sex, and utilization of mechanical ventilation. Impaired inflammatory response and decreased mobility in individuals with pneumonia may predispose these individuals to develop pressure ulcers. Surveillance and preventive measures for pressure ulcers should be rigorous in individuals with SCI and pneumonia.

    Hajj pilgrimage is the biggest and longest mass gathering in the Muslim world. Annually, about 50% of more than 2.5 million pilgrims participating in this ritual get involved in severe devastating coughs. Most coughs continue, so the pilgrims turn back home and transmit them to family members and other people. Despite the high prevalence of coughs for many years, what causes them remains unknown. Considering the pertussis-like clinical picture of the so-called "hajj coughs", the researchers conducted a study to measure antibodies against three known common atypical bacteria, namely Bordetella Pertussis, Chlamydia Pneumonia and Mycoplasma Pneumonia. The study was done on three out of eleven groups of pilgrims from Yazd province, central Iran. The sample was selected randomly and consisted of 202 pilgrims who completed an informed consent. Their blood samples were taken, and the plasma was separated and then stored at -70 °C. After turning back from the journey, the pilgrims had their second blood samples taken. As many as 52 pilgrims failed to come for the second sampling, and two samples were broken during transportation. The final analysis was performed on the remaining 148 pairs of samples. Antibodies were already elevated in many pilgrims before the journey probably due to their old age (causing more exposure to pathogens) or unplanned pertussis vaccination. After their return, antibody elevation was only mild, again probably due to the old age of the participants (i.e. due to their weaker immune systems). Some antibodies even fell down without any known reason. In this study, previous hajj journey was assumed as a prophylactic factor, due to acquisition of immunity. Coughs with a prolonged pertussis-like picture were also presumed to be more related than other types of coughs to atypical pathogens. Statistical tests showed that the history of previous journeys had no prophylactic effect. Also, no correlation was found between the clinical pictures of coughs

    Delirium is common in critically ill patients and impact in-hospital mortality in patients with pneumonia. The aim of the study was to evaluate the prevalence of delirium symptoms during hospitalization in patients with severe pneumonia and their impact on one-year mortality. This was an observational, retrospective, cohort study of consecutive patients admitted to the respiratory high dependency unit of the San Gerardo University Hospital, Monza, Italy, between January 2009 and December 2012 with a diagnosis of severe pneumonia. A search through the charts looking for ten key words associated with delirium (confusion, disorientation, altered mental status, delirium, agitation, inappropriate behavior, mental status change, inattention, hallucination, lethargy) was performed by a multidisciplinary team. The primary endpoint was mortality at one-year follow-up. Secondary endpoint was in-hospital mortality. A total of 172 patients were enrolled (78 % males; median age 75 years). At least one delirium symptom was detected in 53 patients (31 %) during hospitalization. The prevalence of delirium symptoms was higher among those who died during hospitalization vs. those who survived (44 vs. 27 %, p = 0.049, respectively). Seventy-one patients (46 %) died during the one-year follow-up. The prevalence of at least one delirium symptom was higher among those who died than those who survived during the one-year follow-up (39 vs. 21 %, p = 0.014, respectively). At the multivariable logistic regression analysis, after adjustment for age, comorbidities and severe sepsis, the presence of at least one delirium symptom during hospitalization was an independent predictor of one-year mortality (OR 2.35; 95 % CI 1.13-4.90; p = 0.023). Delirium symptoms are independent predictors of one-year mortality in hospitalized patients with severe pneumonia. Further studies should confirm our results using prospective methods of collecting data.

    Full Text Available Abstract Introduction Post-infectious autoimmune demyelination of the central nervous system is a rare neurological disorder typically associated with exanthematous viral infections. We report an unusual presentation of the condition and a previously undocumented association with Streptococcus pneumonia meningitis. Case presentation A 50-year-old Caucasian woman presented to our facility with an acute myelopathy three days after discharge following acute Streptococcus pneumoniae meningitis. Imaging studies of the spine ruled out an infective focus and no other lesions were seen within the cord. Diffuse, bilateral white matter lesions were seen within the cerebral hemispheres, and our patient was diagnosed as having a post-infective demyelination syndrome that met the diagnostic criteria for an acute transverse myelitis. Our patient clinically and radiologically improved following treatment with steroids. Conclusions The novel association of a Streptococcus pneumoniae infection with post-infectious autoimmune central nervous system demyelination should alert the reader to the potentially causative role of this common organism, and gives insights into the pathogenesis. The unusual dissociation between the clinical presentation and the location of the radiological lesions should also highlight the potential for the condition to mimic the presentation of others, and stimulates debate on the definitions of acute transverse myelitis and acute disseminated encephalomyelitis, and their potential overlap.

    Recent studies have left absolutely no doubt that tobacco increases susceptibility to bacterial lung infection, even in passive smokers. This relationship also shows a dose-response effect, since the risk reduces spectacularly 10 years after giving up smoking, returning to the level of non-smokers. Streptococcus pneumoniae is the causative microorganism responsible for community-acquired pneumonia (CAP) most frequently associated with smoking, particularly in invasive pneumococcal disease and septic shock. It is not clear how it acts on the progress of pneumonia, but there is evidence to suggest that the prognosis for pneumococcal pneumonia is worse. In CAP caused by Legionella pneumophila, it has also been observed that smoking is the most important risk factor, with the risk rising 121% for each pack of cigarettes smoked a day. Tobacco use may also favor diseases that are also known risk factors for CAP, such as periodontal disease and upper respiratory viral infections. By way of prevention, while giving up smoking should always be proposed, the use of the pneumococcal vaccine is also recommended, regardless of the presence of other comorbidities.

    Objective To investigate pneumonia risk among patients with unilateral vocal fold paralysis (UVFP). Study Design Retrospective population-based cohort study. Setting This study used data from the National Health Insurance Research Database of Taiwan, a nationwide population-based database. Subjects and Methods A total of 419 patients newly diagnosed with UVFP between January 1, 1997, and December 31, 2013, were identified from the Longitudinal Health Insurance Database 2000, a nationally representative database of 1 million randomly selected patients. Moreover, 1676 patients without UVFP were matched to patients with UVFP at a 1:4 ratio based on age, sex, socioeconomic status, urbanization level, and site-specific cancers. Patients were followed up until death or the end of the study period (December 31, 2013). The primary outcome was the occurrence of pneumonia. Results The cumulative incidence of pneumonia was significantly higher for patients with UVFP than those without UFVP ( P < .001). The adjusted Cox proportional hazard model showed that UVFP was significantly associated with a higher incidence of pneumonia (hazard ratio, 1.97; 95% CI, 1.35-2.86; P < .001). Subgroup analyses demonstrated that UVFP was an independent risk factor of pneumonia for 4 subgroups: young (18-50 years), older (≥51 years), male, and cancer. Conclusion This is the first nationwide population-based cohort study to investigate the association between UVFP and pneumonia. The findings indicate that UVFP is an independent risk factor of pneumonia. Given the study results, physicians should be aware of the potential for pneumonia occurrence following UVFP.

    Full Text Available Abstract Background Mycoplasma pneumoniae is an important cause of respiratory tract infection and is increasingly being associated with other diseases such as asthma and extra-pulmonary complications. Considerable cross-reactivity is known to exist between the whole cell antigens used in the commercial serological testing assays. Identification of specific antigens is important to eliminate the risk of cross-reactions among different related organisms. Adherence of M. pneumoniae to human epithelial cells is mediated through a well defined apical organelle to which a number of proteins such as P1, P30, P116 and HMW1-3 have been localized, and are being investigated for adhesion, gliding and immunodiagnostic purposes. Methods A 609 bp fragment P116(N-27, corresponding to the N-terminal region of M. pneumoniae P116 gene was cloned and expressed. A C-terminal fragment P1(C-40, of P1 protein of M. pneumoniae was also expressed. Three IgM ELISA assays based on P116(N-27, P1(C-40 and (P116 (N-27 + P1(C-40 proteins were optimized and a detailed analysis comparing the reactivity of these proteins with a commercial kit was carried out. Comparative statistical analysis of these assays was performed with the SPSS version 15.0. Results The expressed P116(N-27 protein was well recognized by the patient sera and was immunogenic in rabbit. P1(C-40 of M. pneumoniae was also immunogenic in rabbit. In comparison to the reference kit, which is reported to be 100% sensitive and 75% specific, ELISA assay based on purified P116(N-27, P1(C-40 and (P116(N-27 + P1(C-40 proteins showed 90.3%, 87.1% and 96.8% sensitivity and 87.0%, 87.1% and 90.3% specificity respectively. The p value for all the three assays was found to be Conclusion This study shows that an N-terminal fragment of P116 protein holds a promise for serodiagnosis of M. pneumoniae infection. The IgM ELISA assays based on the recombinant proteins seem to be suitable for the use in serodiagnosis of acute M

    Pneumonia is complicated by high rate of mortality and cardiovascular events (CVEs). The potential benefit of aspirin, which lowers platelet aggregation by inhibition of thromboxane A2 production, is still unclear. The aim of the study was to assess the impact of aspirin on mortality in patients with pneumonia. Consecutive patients admitted to the University-Hospital Policlinico Umberto I (Rome, Italy) with community-onset pneumonia were recruited and prospectively followed up until discharge or death. The primary end point was the occurrence of death up to 30 days after admission; the secondary end point was the intrahospital incidence of nonfatal myocardial infarction and ischemic stroke. One thousand and five patients (age, 74.7±15.1 years) were included in the study: 390 were receiving aspirin (100 mg/day) at the time of hospitalization, whereas 615 patients were aspirin free. During the follow-up, 16.2% of patients died; among these, 19 (4.9%) were aspirin users and 144 (23.4%; PFiO(2) ratio <300 negatively influenced survival, whereas aspirin therapy was associated with improved survival. Compared to patients receiving aspirin, the propensity score adjusted analysis confirmed that patients not taking aspirin had a hazard ratio of 2.07 (1.08 to 3.98; P=0.029) for total mortality. This study shows that chronic aspirin use is associated with lower mortality rate within 30 days after hospital admission in a large cohort of patients with pneumonia. © 2015 The Authors.

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

    Purpose: To evaluate what is useful among various parameters including CT findings, laboratory parameters (%VC, %DLco, KL-6), patients related data (age, sex, duration of disease) to discriminate between responder and non-responder in patients who received autologous peripheral blood stem cell transplantation (auto-PBSCT) for interstitial pneumonia (IP) with systemic sclerosis (SSc). Method: Auto-PBSCT and follow-up of at least one year by chest CT, serum KL-6, %VC, and %DLco were performed in 15 patients for IP with SSc. Analyzed CT findings included extent of ground-glass opacity (GGO), intralobular reticular opacity, number of segments that showed traction bronchiectasis, and presence of honeycombing. We regarded the therapeutic response of patients as responders when TLC or VC increase over 10% or DLco increase more than 15%, otherwise we have classified as non-responder. We applied univariate and multivariate analyses to find the significant indicators to discriminate responders from non-responders. P < 0.05 was considered statistically significant. Results: Univariate and multivariate analyses showed that the significant parameter to discriminate responders from non-responders were pretreatment KL-6, presence of honeycombing, extent of GGO, and early change in extent of GGO. Among them, extent of GGO and early change in extent of GGO were the strongest discriminators between responders and non-responders (P = 0.001, 0.001, respectively). Conclusion: Several CT findings and pretreatment KL-6 may be useful to discriminate between responder and non-responder in patients who received auto-PBSCT for IP with SSc.

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

    To determine whether oropharyngeal dysphagia is a risk factor for readmission for pneumonia in elderly persons discharged from an acute geriatric unit. Observational prospective cohort study with data collection based on clinical databases and electronic clinical notes. All elderly individuals discharged from an acute geriatric unit from June 2002 to December 2009 were recruited and followed until death or December 31, 2010. All individuals were initially classified according to the presence of oropharyngeal dysphagia assessed by bedside clinical examination. Main outcome measure was readmission for pneumonia. Clinical notes were reviewed by an expert clinician to verify diagnosis and classify pneumonia as aspiration or nonaspiration pneumonia. A total of 2,359 patients (61.9% women, mean age 84.9 y) were recruited and followed for a mean of 24 months. Dysphagia was diagnosed in 47.5% of cases. Overall, 7.9% of individuals were readmitted for pneumonia during follow-up, 24.2% of these had aspiration pneumonia. The incidence rate of hospital readmission for pneumonia was 3.67 readmissions per 100 person-years (95% CI 3.0-4.4) in individuals without dysphagia and 6.7 (5.5-7.8) in those with dysphagia, with an attributable risk of 3.02 readmissions per 100 person-years (1.66-4.38) and a rate ratio of 1.82 (1.41-2.36). Multivariate Cox regression showed an independent effect of oropharyngeal dysphagia, with a hazard ratio of 1.6 (1.15-2.2) for hospitalization for pneumonia, 4.48 (2.01-10.0) for aspiration pneumonia, and 1.44 (1.02-2.03) for nonaspiration pneumonia. Oropharyngeal dysphagia is a very prevalent and relevant risk factor associated with hospital readmission for both aspiration and nonaspiration pneumonia in the very elderly persons.

    Full Text Available Studies focused on the pathological-radiological correlation of human Mycoplasma (M pneumoniae pneumonia have rarely been reported. Therefore, we extensively reviewed the literature regarding pathological and radiological studies of Mycoplasma pneumonia, and compared findings between open lung biopsy specimen and computed tomography (CT. Major three correlations were summarized. 1 Peribronchial and perivascular cuffing characterized by mononuclear cells infiltration was correlated with bronchovascular bundles thickening on CT, which was the most common finding of this pneumonia. 2 Cellular bronchitis in the small airways accompanied with exudates or granulation tissue in the lumen revealed as centrilobular nodules on CT. 3 Neutrophils and exudates in the alveolar lumen radiologically demonstrated as air-apace consolidation or ground-glass opacities. In M.pulmonis-infected mice model, pathologic patterns are strikingly different according to host cell-mediated immunity (CMI levels; treatment with interleukin-2 lead to marked cellular bronchitis in the small airways and treatment with prednisolone or cyclosporin-A lead to neutrophils and exudates in the alveolar lumen. Patients with centrilobular nodules predominant radiologic pattern have a high level of CMI, measuring by tuberculin skin test. From these findings, up-regulation of host CMI could change radiological pattern to centrilobular nodules predominant, on the other hand down-regulation of host CMI would change radiological pattern to ground-glass opacity and consolidation. It was suggested the pathological features of M. pneumoniae pneumonia may be altered by the level of host CMI.

    In patients with a clinical suspicion of pneumonia, typical clinical and laboratory features along with the detection of infiltrates on chest X-ray are as a rule considered diagnostic and therapy is immediately initiated; however, studies have shown that in up to 5% of patients with an initial suspicion of pneumonia, another noninfectious pulmonary disease was the underlying cause. Early recognition and differentiation of diseases mimicking pneumonia are prerequisites for an adequate therapy. The aim of this review is to present the important noninfectious differential diagnoses of pneumonia and to provide the reader with tools for a systematic diagnostic approach. A literature search was carried out. As alterations in the lungs often result in similar imaging appearances and a differentiation between transudates, exsudates, blood and cells is not feasible by chest X-ray or CT, a systematic approach is essential to make an appropriate diagnosis. Hence, consideration of the temporal course, predominant pattern, distribution of findings, additional findings and clinical presentation are indispensable. (orig.)

    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.

    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).

    To analyze the radiographic and HRCT findings of Pneumocystic carinii pneumonia. We reviewed the medical records and retrospectively analysed the chest radiographs(n=31) and HRCT scans(n=17) of 31 patients with Pneumocystis carinii pneumonia who had been followed up at our institute between, 1993 and March 1998. Pneumocystis carinii pneumonia was confirmed by cytologic evaluation of sputum stained with methenamine silver(n=25) or on the basis of clinical history(n=6). The study group included 17 men and 14 women aged 28-78(average, 53.6) years. Twenty-eight patients had underlying conditions such as hematologic diseases(n=13), AIDS(n=8), malignancy(n=2), DM(n=2) and malnutrition(n=1), and three were free from underlying diseases. Twenty patients had pure Pneumocystis carinii pneumonia and 11 had combined lung diseases, namely pulmonary tuberculosis(n=4), pulmonary metastasis(n=2), bacterial pneumonia(n=2), atypical mycobacterial infection(n=1), pulmonary edema(n=1), and Kaposi' s sarcoma(n=1). Chest radiographic findings of 20 cases of pure Pneumocystis carinii pneumonia included consolidation(n=12), linear-reticular opacity(n=8), ill defined haziness(n=7), and nodules(n=6), with bilaterality in is cases and zonal predominance in ten [central(n=5), lower(n=5)]. Ancillary findings included pleural effusion(n=10), cysts(n=5), lymphadenopathy(n=4) and pneumothorax(n=1). In two patients, findings were entirely normal. HRCT findings in ten cases of pure Pneumocystis carinii pneumonia included ground-glass opacity(n=6), consolidation(n=6), linear-reticular opacity(n=8), and nodules(n=5), with bilaterallity in seven cases and zonal predominance in five [central(n=5), lower(n=2)]. Ancillary findings among these cases included pleural effusion(n=4), lymphadenopathy(n=2), cysts(n=1), and pneumothorax(n=1).

    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

    The purpose of this study was to determine the diagnostic value of percutaneous core needle biopsy (CNB) relative to fine needle aspiration (FNA) in patients with pneumonia and pneumonia mimics. In this prospective study we present our experience with 48 thoracic FNAs and CNBs carried out on 48 patients with pneumonia and pneumonia mimics. Samples were obtained from all patients using both CNB (with an automated 18-G core biopsy needle and a gun) and FNA (with a 22-G needle). A specific diagnosis was made in 10/48 cases (20.83%) by FNA and in 42/48 (87.5%) by CNB. The main complications encountered were pneumothorax (n = 4) and hemoptysis (n = 2), yielding a total complication rate of 12.5%. We concluded that CNB using an automated biopsy gun results in a higher diagnostic accuracy for pneumonia and pneumonia mimic biopsies than FNA. Complications should be considered and proper patient observation should follow the procedure

    In a collection of 58 snakes comprising predominantly Eurasian vipers in Switzerland, five snakes died unexpectedly during hibernation from 2009 to 2012. In one snake, organisms resembling chlamydiae were detected by immunohistochemistry in multiple histiocytic granulomas. Real-time quantitative PCR and microarray analysis were used to determine the presence of Chlamydia pneumoniae in tissue samples and cloacal/choanal swabs from snakes in the collection; 8/53 (15.1%) of the remaining snakes were positive. Although one infected snake had suppurative periglossitis, infection with C. pneumoniae did not appear to be associated with specific clinical signs in snakes. Of seven snakes treated with 5 mg/kg marbofloxacin IM once daily, five became PCR negative for C. pneumoniae following treatment, whereas one animal remained positive and one snake was lost to follow-up.

    Treatment of childhood pneumonia is a key priority in low-income countries, with substantial resource implications. WHO revised their guidelines for the management of childhood pneumonia in 2013. We estimated and compared the resource requirements, total direct medical cost and cost-effectiveness of childhood pneumonia management in 74 countries with high burden of child mortality (Countdown countries) using the 2005 and 2013 revised WHO guidelines. We constructed a cost model using a bottom up approach to estimate the cost of childhood pneumonia management using the 2005 and 2013 WHO guidelines from a public provider perspective in 74 Countdown countries. The cost of pneumonia treatment was estimated, by country, for year 2013, including costs of medicines and service delivery at three different management levels. We also assessed country-specific lives saved and disability adjusted life years (DALYs) averted due to pneumonia treated in children aged below five years. The cost-effectiveness of pneumonia treatment was estimated in terms of cost per DALY averted by fully implementing WHO treatment guidelines relative to no treatment intervention for pneumonia. Achieving full treatment coverage with the 2005 WHO guidelines was estimated to cost US$ 2.9 (1.9-4.2) billion compared to an estimated US$ 1.8 (0.8-3.0) billion for the revised 2013 WHO guidelines in these countries. Pneumonia management in young children following WHO treatment guidelines could save up to 39.8 million DALYs compared to a zero coverage scenario in the year 2013 in the 74 Countdown countries. The median cost-effectiveness ratio per DALY averted in 74 countries was substantially lower for the 2013 guidelines: US$ 26.6 (interquartile range IQR: 17.7-45.9) vs US$ 38.3 (IQR: US$ 26.2-86.9) per DALY averted for the 2005 guideline respectively. Child pneumonia management as detailed in standard WHO guidelines is a very cost-effective intervention. Implementation of the 2013 WHO guidelines is

The risk of death was also high in patients presenting hepatic cancer (OR = 2.5 or steroid therapy (OR = 2.4 who developed pulmonary hemorrhage as the histological pattern of secondary interstitial pneumonia . The risk of death by lung metastasis was also elevated (OR = 1.6 for patients that were immunosuppressed after radiotherapy. CONCLUSION: Patients with secondary immunosuppression who developed secondary interstitial pneumonia during treatment in hospital should be evaluated to avoid death by diffuse alveolar damage, pulmonary edema, bronchopneumonia, lung hemorrhage, pulmonary thromboembolism, or lung metastasis. The high-risk patients are those immunosuppressed by hematologic disease; those under steroid treatment; or those with colon or hepatic carcinoma, cachexia, or arterial hypertension.OBJETIVO: Apresentar as associações mais freqüentes encontradas em autópsias de pacientes imunossuprimidos que desenvolveram pneumonia intersticial secundária bem como o risco de óbito (Odds Ratio de desenvolver PIS associada à causa da imunossupressão.

    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.)

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

    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.)

    Although pneumonia is a leading cause of inpatient mortality, deaths may also occur after discharge from hospital. However, prior studies have been small, in selected groups or did not fully evaluate risk factors, particularly malnutrition and HIV. We determined 1-year post-discharge mortality and risk factors among children diagnosed with severe pneumonia. A cohort study of children aged 1-59 months admitted to Kilifi County Hospital with severe pneumonia (2007-12). The primary outcome was death pneumonia, 1041 (25%) had severe acute malnutrition (SAM), 267 (6.4%) had a positive HIV antibody test, and 364 (8.7%) died in hospital. After discharge, 2279 KHDSS-resident children were followed up; 70 (3.1%) died during 2163 child-years: 32 (95% confidence interval (CI) 26, 41) deaths per 1000 child years. Post-discharge mortality was greater after admission for severe pneumonia than for other diagnoses, hazard ratio 2.5 (95% CI 1.2, 5.3). Malnutrition, HIV status, age and prolonged hospitalisation, but not signs of pneumonia severity, were associated with post-discharge mortality. Fifty-two per cent (95% CI 37%, 63%) of post-discharge deaths were attributable to low mid-upper arm circumference and 11% (95% CI 3.3%, 18%) to a positive HIV test. Admission with severe pneumonia is an important marker of vulnerability. Risk stratification and better understanding of the mechanisms underlying post-discharge mortality, especially for undernourished children, are needed to reduce mortality after treatment for pneumonia. © 2017 The Authors.

    2017-01-01

    In patients with a clinical suspicion of pneumonia, typical clinical and laboratory features along with the detection of infiltrates on chest X-ray are as a rule considered diagnostic and therapy is immediately initiated; however, studies have shown that in up to 5% of patients with an initial suspicion of pneumonia, another noninfectious pulmonary disease was the underlying cause. Early recognition and differentiation of diseases mimicking pneumonia are prerequisites for an adequate therapy. The aim of this review is to present the important noninfectious differential diagnoses of pneumonia and to provide the reader with tools for a systematic diagnostic approach. A literature search was carried out. As alterations in the lungs often result in similar imaging appearances and a differentiation between transudates, exsudates, blood and cells is not feasible by chest X-ray or CT, a systematic approach is essential to make an appropriate diagnosis. Hence, consideration of the temporal course, predominant pattern, distribution of findings, additional findings and clinical presentation are indispensable. (orig.) [de

    Full Text Available RESUMO: Objetivo: Descrever os óbitos com menção de sepse pulmonar, medir a associação entre sepse pulmonar e pneumonia, assim como avaliar o impacto da regra de codificação no perfil de mortalidade, com a inclusão simulada do diagnóstico de pneumonia, nas declarações de óbito (DO com menção de sepse pulmonar, no Rio de Janeiro, em 2011. Métodos: Foram identificados os óbitos com menção de sepse pulmonar independentemente da causa básica. Aos médicos atestantes, aplicou-se questionário medindo a associação entre sepse pulmonar e pneumonia. O registro de pneumonia nos prontuários dos óbitos com menção de sepse pulmonar e sem menção de pneumonia na DO foi investigado. Foi descrito o perfil de mortalidade após a inclusão simulada do código de pneumonia nas declarações com sepse pulmonar. Resultados: Sepse pulmonar correspondeu a 30,9% das menções de sepse e a menção de pneumonia estava ausente em 51,3% dessas declarações. Pneumonia constava em 82,8% da amostra de prontuários investigados. Dos médicos entrevistados, 93,3% relataram pneumonia como a mais frequente causa de sepse pulmonar. A simulação revelou que a inclusão da pneumonia alterou a causa básica de 7,8% dos óbitos com menção de sepse e 2,4% de todos os óbitos, independentemente da causa original. Conclusão: Sepse pulmonar está associada à pneumonia e a simples inclusão do código de pneumonia nas declarações de óbito com menção de sepse pulmonar impactaria o perfil de mortalidade, apontando necessidade de aprimoramento das regras de codificação na Classificação Internacional de Doenças (CID-10.

    It is not always easy to detect and interpret radiologic findings of pediatric pneumonia. Authors retrospectively analysed radiologic findings of 102 cases of pediatric primary pneumonia treated at Yeong-Deung-Po City Hospital between 1988 and 1990 to understand the past trend of radiologic pattern and to attain helpful information in diagnosing pediatric pneumonia hereafter. Results were as follows. Positive radiologic findings were noted in 85 cases (84%), but 17 cases (16%) showed indefinite lesion. The cases of infantile pneumonia (under 1 year of age) were 44. The most frequent finding was bilateral peribronchial infiltration with overearation (21 cases, 48%), followed by multiple patchy atelectasis associated with the findings of bilateral peribronchial infiltration and overaeration (nine cases, 23%), peribronchial infiltration without definite overaeration (six cases, 14%), alveolar consolidation superimposed on the peribronchial infiltration (three cases, 6%), alveolar consolidation (three cases, 6%) and bronchopneumonic pattern (two cases, 4%). The cases of pre-school age (1-5 years of age) were 34. Bilateral parahilar peribronchial infiltration was the most frequent finding (24 cases, 71%), followed by alveolar consolidation (six cases, 17%) and bronchopneumonic pattern (four cases, 12%). The cases of school age (over 6 years of age) were seven. Six cases (85%) showed alveolar consolidation and one case (15%) showed bronchopneumonic pattern. In short, the younger the patient was, the more frequently the interstitial infiltration occurred. Furthermore, overaeration and patchy atelectasis were unique findings of infantile pneumonia. After the school age, the pattern of pneumonia became similar to that of adults

    Objective: To explore the Spiral CT manifestations and differential diagnosis of spherical pneumonia. Methods: 18 cases of spherical pneumonia and 20 cases of peripheral pulmonary carcinoma were selected, both of them were confirmed by clinic and/or pathology. The SCT findings of both groups were compared retrospectively. Results: Main spiral CT findings of spherical pneumonia were showed as followings: square or triangular lesions adjacent to pleura; with irregular shape, blurry, slightly lobulated margin, sometimes with halo sign. Small inflammatory patches and intensified vascular markings around the lesions were seen. Lesions became smaller or vanished after short-term anti-inflammatory treatment. Conclusion: Spherical pneumonia showed some characteristics on Spiral CT scan, which are helpful in diagnosis and differential diagnosis of this disease. (authors)

    Loss of protective airway reflexes in patients with acute coma puts these patients at risk of aspiration pneumonia complicating the course of the primary disease. Available data vary considerably with regard to bacteriology, role of anaerobic bacteria, and antibiotic treatment. Our objective was to research the bacteriology of aspiration pneumonia in acute coma patients who were not pre-treated with antibiotics or hospitalized within 30 days prior to the event. We prospectively analyzed 127 patient records from adult patients admitted, intubated and ventilated to a tertiary medical intensive care unit with acute coma. Bacteriology and antibiotic resistance testing from tracheal aspirate sampled within 24 h after admission, blood cultures, ICU scores (APACHE II, SOFA), hematology, and clinical chemistry were assessed. Patients were followed up until death or hospital discharge. The majority of patients with acute coma suffered from acute cardiovascular disorders, predominantly myocardial infarction, followed by poisonings, and coma of unknown cause. In a majority of our patients, microaspiration resulted in overt infection. Most frequently S. aureus, H. influenzae, and S. pneumoniae were isolated. Anaerobic bacteria (Bacteroides spec., Fusobacteria, Prevotella spec.) were isolated from tracheal aspirate in a minority of patients, and predominantly as part of a mixed infection. Antibiotic monotherapy with a 2nd generation cephalosporin, or a 3rd generation gyrase inhibitor, was most effective in our patients regardless of the presence of anaerobic bacteria.

    Full Text Available Resumo: O diagnóstico e tratamento da pneumonia adquirida na comunidade (PAC são assuntos sobre os quais existe pouco consenso, o que se exprime por uma proliferação de normas de prática clínica cujas recomendações divergem significativamente. O presente estudo teve por objectivos a validação clínica, considerando a realidade portuguesa, das recomendações das cinco normas de prática clínica mais divulgadas, designadamente as da British Thoracic Society, American Thoracic Society, Infectious Diseases Society of America, European Respiratory Society e Sociedade Portuguesa de Pneumologia, e a avaliação do lugar dos macrólidos no tratamento da PAC. O estudo utilizou a metodologia Delphi, tendo sido desenvolvido um questionário contendo todas as recomendações individuais identificadas nas cinco publicações. Foi constituído um painel de 20 peritos nacionais no tratamento da PAC, dos quais 16 participaram efectivamente no estudo, que indicaram numa escala de Likert de 9 pontos o seu grau de concordância com cada uma das recomendações. As opiniões dos membros do painel foram expressas sob a forma de nível de consenso e grau de adequação das recomendações. Os resultados do estudo permitiram identificar as recomendações das diferentes normas de prática clínica que reúnem elevado consenso entre os clínicos, obter estimativas de indicadores epidemiológicos e de padrões de qualidade de cuidados prestados, e ainda identificar as características dos antibióticos consideradas relevantes para a selecção inicial da terapêutica empírica. A eritromicina apresenta desvantagens em quase todas essas características relativamente aos macrólidos de geração avançada e, entre estes, a azitromicina corresponde mais de perto às preferências dos peritos relativamente às características de tolerabilidade

By the result of microbiological examinations of 149 patients with pneumonia on the background of blood cancer, who have undergone treatment in hematological center of CE “Dnipropetrovsk local multi-field clinical hospital №4” in 2010-2012, bacterial causative agents were determined in 59,7% of accidents, among which gram-negative microorganisms made up 69,7%, gram-positive – 30,3%. In 63% of accidents the asso¬ciations of causative agents were determined: the combination of fungal flora made up 58, 4% bacterial associations – 25, 8%. Invasive methods of research have demonstrated a considerably bigger informativeness in determination of possible etiological diagnosis of pneumonia. In determination of causative agent in fluid of brochoalveolar lavage the part of positive results made up 77,4% against 30,3% in examination of sputum.

    Full Text Available Aortic Valve Stenosis (AVS has been explained as an atherosclerotic process of the valve as they often exhibit inflammatory changes with infiltration of macrophages, T lymphocytes and lipid infiltration. The present study investigated whether the bacteria Chlamydia pneumoniae (CP and Mycoplasma pneumoniae (MP, detected previously in atherosclerotic plaques, are also present in AVS. Ten valves surgically removed from patients with AVS were analyzed by immunohistochemistry, in situ hybridization, and electron microscopy. The mean and standard deviation of the percentage areas occupied by CP antigens and MP - DNA were respectively 6.21 +/- 5.41 and 2.27 +/- 2.06 in calcified foci; 2.8 +/- 3.33 and 1.78+/- 3.63 in surrounding fibrotic areas, and 0.21 +/- 0.17 and 0.12 +/- 0.13 in less injured parts of the valve. There was higher amount of CP and MP in the calcified foci and in the surrounded fibrosis than in more preserved valvular regions. In conclusion, the fact that there were greater amounts of CP and MP in calcification foci of AVS favors the hypothesis that AS is not an inevitable degenerative process due to aging, but rather that it may be a response to the presence of these bacteria, similarly to the morphology detected in atherosclerosis damage.Estenose da Valva Aórtica (EVA tem sido considerada como um processo aterosclerótico das valvas pois elas freqüentemente exibem alterações inflamatórias com acúmulo de macrófagos e linfócitos T, bem como infiltração de lípides. O presente estudo investigou se as bactérias Chlamydia pneumoniae (CP e Mycoplasma pneumoniae (MP, detectadas previamente em placas ateroscleróticas, estavam presentes na EVA. Dez valvas removidas cirúrgicamente de pacientes com EVA foram analisadas pela imunohistoquímica, hibridização in situ e microscopia eletrônica.

    Abstract Pneumonia is a frequent complication in dementia patients and is associated with high mortality rates. The aim of this retrospective cohort study was to determine whether traditional Chinese medicine (TCM) therapy can decrease pneumonia risk in dementia patients. The cohort dataset was obtained from the Longitudinal Health Insurance Database 2005, a sublibrary of the National Health Insurance Research Database, containing all medical data of 1 million beneficiaries, randomly selected from the all Insurers in year 2005. Newly diagnosed dementia patients (n = 9712) without pneumonia were analyzed from January 1997 to December 2003. After matching by sex, age, urban level, Charlson comorbidity index, insured amount, and comorbidities, 1376 pairs (1:1) of TCM and non-TCM users were acquired. Every dementia patient was individually recorded from 1997 to 2012 to identify pneumonia incidence (onset after 3 months of dementia diagnosis). Demographic characteristics, Charlson comorbidity index, comorbidities, behavioral and psychological symptoms of dementia, and psychotropic drugs were also investigated. Cox proportional regression was used to compute hazard ratios and 95% confidence intervals (CIs) after adjustment for the above-mentioned variables. There were 419 (30.5%) and 762 (55.4%) pneumonia cases in the TCM and non-TCM cohorts during a mean follow-up period of 7.6 years. The adjusted hazard ratios (95% CI) for pneumonia admission was 0.62 (0.55–0.70) for the TCM group. Patients who received TCM therapy at higher cumulative doses or for longer periods experienced increased protection from pneumonia admission. Ma-Xing-Gan-Shi-Tang, Yin-Qiao-San, and Xiao-Qing-Long-Tang might represent possible formulae reducing the incidence of pneumonia. TCM might be associated with a lower risk of pneumonia in dementia patients. PMID:27631269

    2016-07-01

    Neuromyelitis optica causes bilateral optic neuritis and longitudinal extensive transverse myelitis. Although usually sporadic, 3% of cases of neuromyelitis optica are familial. The interval over which attacks continue and the long term prognosis for pediatric-onset neuromyelitis optica are not well defined. We describe two patients with pediatric familial neuromyelitis optica with the longest clinical follow-up of a pediatric case reported in the literature to our knowledge. One woman developed blindness with bilateral eye involvement within a few weeks at age 3. This was followed by transverse myelitis with paraparesis at age 19 leading to diagnosis of neuromyelitis optica. Her serum anti-aquaporin 4 antibody was later found to be positive. She continued with sporadic myelitis-related relapses but remained ambulant until age 40 when she had a more severe relapse. There was evidence of longitudinal extensive T2 hyperintensity in the thoracic spinal cord. Her sister also developed blindness at age 3.5 followed by myelitis 1year later with multiple relapses of gait impairment until her death from pneumonia at age 21. These patients represent the rare occurrence of neuromyelitis optica in children within the same family and show that this disease can have prolonged periods of remission but a continued tendency to relapse, supporting the need for lifelong immunosuppression.

    Characterization and follow-up evaluation of chest CT of RSV pneumonia in immune-compromised adults during a seasonal epidemic. Retrospective analysis of 132 chest CT examinations of 51 adult immune-compromised patients (29 m/22f, diameter 58 years) with clinical signs of pneumonia and positive RSV test in winter 2011/2012. Two experienced chest radiologists evaluated the morphology (bronchial wall thickening, tree-in-bud, nodules, halo, ground-glass opacities, consolidations, pleural fluid) of the CT scans by consensus. Pathological findings were in 86 % of the chest CT scans: Areas of ground-glass attenuation in 64 %, consolidations in 56 %, nodules in 55 % (diameter 8 mm in maximal diameter, with halo in 71 %), pleural fluid in 44 % (diameter 2 cm), tree-in-bud in 36 %, bronchial wall thickening in 27 % and more than one morphological finding in 72 %. There were no pathological CT findings in 14 % of patients with clinical symptoms of pneumonia because these patients did not undergo follow-up. Radiological progression was found in 45 % of patients and regression in 33 % in follow-up examinations. In 37 % an additional examination of the paranasal sinuses was performed and showed sinusitis in 63 % of cases. 90 % of the patients had sinusitis as well as pneumonia. In addition to RSV, a further pathogenic agent was found in bronchoalveolar lavage of five patients (Aspergillus spec., herpes simplex virus, Pseudomonas aeruginosa). The most characteristic signs in chest CT scans were at the beginning of pneumonia with nodules and tree-in-bud often combined with bronchial wall thickening. The following CT scans showed characteristic but not pathognomonic chest CT findings of RSV pneumonia. These morphological findings should be recognized seasonally (winter) especially at the beginning of the case of pneumonia. RSV-associated additional sinusitis is probably common and should be noticed.

    Epidemiological analyses demonstrate that pneumonia survivors have a higher risk of myocardial infarction than people with similar load of risk factors for atherosclerotic cardiovascular disease (ASCVD) but without pneumonia. This may be due to a higher baseline burden of ASCVD in patients with pneumonia that is not captured by the accounting of known ASCVD risk factors in epidemiological analyses or to unfavorable accelerating effects of pneumonia on atherosclerosis. We analyzed data from the Multi-Ethnic Study of Atherosclerosis. We identified 54 participants that were hospitalized for pneumonia during study follow-up and that also had assessment of coronary artery calcium (CAC, an objective marker of coronary atherosclerotic burden) before and after this hospitalization. We matched them to 54 participants who were not hospitalized for pneumonia but that had CAC assessments at the same study visits as the pneumonia cases. We compared baseline CAC scores and their progression between groups. Baseline CAC scores were similar in both groups (median [IQR]; 6.3 [0-356.8] in pneumonia participants vs. 10.8 [0-178.3] in controls; p = 0.25). After a median of 4.8 years, the direction and magnitude of CAC score change, and the slope of CAC score progression between groups was also similar (median change [IQR], 21.8 [0 to 287.29] in participants with pneumonia versus 15.8 [0 to 140.94] in controls, p = 0.28; difference in slope, 7.7, 95% CI -9.0 to 24.6, p = 0.18). However, among participants with high baseline ASCVD risk (i.e. ACC/AHA 10-year risk estimate ≥7.5%), participants with pneumonia showed a larger increase in CAC scores (median change [IQR]; 159.10 [38.55-407.34] versus 48.72 [0.97-246.99] in controls; p = 0.02) and a trend towards a steeper slope of CAC score progression (difference in slope, 19.7, 95% CI -6.6 to 45.6, p = 0.07). Pneumonia may accelerate the progression of atherosclerosis in people with high baseline ASCVD risk.

    To report a case of late postoperative endophthalmitis caused by Streptococcus pneumoniae and conjunctival necrosis by Streptococcus pneumoniae and Mycobacterium fortuitum following Ahmed glaucoma valve (AGV) surgery in a young patient. Case report of a 13-year-old boy with purulent exudates and extensive conjunctival necrosis two months following amniotic membrane graft and conjunctival closure (for conjunctival retraction post AGV for secondary glaucoma). The conjunctiva showed extensive necrosis causing exposure of the tube and plate associated with frank exudates in the area adjoining the plate and anterior chamber mandating explantation of the plate along with intravitreal antibiotics. The vitreous aspirate grew Streptococcus pneumoniae while Streptococcus pneumoniae with Mycobacterium fortuitum was isolated from the explanted plate. Despite adequate control of infection following surgery, the final visual outcome was poor owing to disc pallor. Conjunctival necrosis and retraction post-AGV can cause late postoperative co-infections by fulminant and slow-growing organisms. A close follow-up is therefore essential in these cases to prevent sight-threatening complications.

    The multidrug resistance profiles of Klebsiella pneumoniae carbapenemase (KPC) producers have led to increased clinical polymyxin use. Combination therapy with polymyxins may improve treatment outcomes, but it is uncertain which combinations are most effective. Clinical successes with intravenous minocycline-based combination treatments have been reported for infections caused by carbapenemase-producing bacteria. The objective of this study was to evaluate the in vitro activity of polymyxin B and minocycline combination therapy against six KPC-2-producing K. pneumoniae isolates (minocycline MIC range, 2 to 32 mg/liter). Polymyxin B monotherapy (0.5, 1, 2, 4, and 16 mg/liter) resulted in a rapid reduction of up to 6 log in bactericidal activity followed by regrowth by 24 h. Minocycline monotherapy (1, 2, 4, 8, and 16 mg/liter) showed no reduction of activity of >1.34 log against all isolates, although concentrations of 8 and 16 mg/liter prolonged the time to regrowth. When the therapies were used in combination, rapid bactericidal activity was followed by slower regrowth, with synergy (60 of 120 combinations at 24 h, 19 of 120 combinations at 48 h) and additivity (43 of 120 combinations at 24 h, 44 of 120 combinations at 48 h) against all isolates. The extent of killing was greatest against the more susceptible polymyxin B isolates (MICs of ≤0.5 mg/liter) regardless of the minocycline MIC. The pharmacodynamic activity of combined polymyxin B-minocycline therapy against KPC-producing K. pneumoniae is dependent on polymyxin B susceptibility. Further in vitro and animal studies must be performed to fully evaluate the efficacy of this drug combination. Copyright © 2017 American Society for Microbiology.

    We aimed to assess the prospective association of cardiorespiratory fitness (CRF) with the risk of pneumonia. Cardiorespiratory fitness, as measured by maximal oxygen uptake, was assessed using a respiratory gas exchange analyzer in 2244 middle-aged men in the Kuopio Ischemic Heart Disease cohort. We corrected for within-person variability in CRF levels using data from repeat measurements taken several years apart. During a median follow-up of 25.8 years, 369 men received a hospital diagnosis of pneumonia. The age-adjusted regression dilution ratio of CRF was 0.58 (95% confidence interval: 0.53-0.63). Cardiorespiratory fitness was linearly associated with pneumonia risk. The hazard ratio (95% confidence interval) for pneumonia per 1 standard deviation increase in CRF in analysis adjusted for several risk factors for pneumonia was 0.77 (0.68-0.87). The association remained consistent on additional adjustment for total energy intake, socioeconomic status, physical activity, and C-reactive protein 0.82 (0.72-0.94). The corresponding adjusted hazard ratios (95% confidence intervals) were 0.58 (0.41-0.80) and 0.67 (0.48-0.95) respectively, when comparing the extreme quartiles of CRF levels. Our findings indicate a graded inverse and independent association between CRF and the future risk of pneumonia in a general male population. Copyright © 2017 Elsevier Inc. All rights reserved.

    Follow-up of obese patient is difficult. There is no literature related to patient follow-up that incorporates the concept of Internet of Things (IoT), use of WiFi, Internet, or portable devices for this purpose. This prospective observational study commenced in June 2011. Patients were prospectively offered to participate in the IoT study group, in which they received a WiFi scale (Withing®, Paris) that provides instant WiFi data to the patient and surgeon. Other patients were admitted to the standard follow-up group at the outpatient clinic. A total of 33 patients were included in our study (ten in the IoT group). Twelve patients did not have WiFi at home, ten lacked of computer knowledge, and seven preferred standard for follow-up. All patients underwent different surgical procedures. There were no complications. Excess weight loss (EWL) was similar in both groups. More than 90% of patients were satisfied. In the IoT group, patients considered it valuable in saving time, and considered seeing their evolution graphics extremely motivating. IoT technology can monitor medical parameters remotely and collect data. A WiFi scale can facilitate preoperative and follow-up. Standard follow-up in a classical outpatient clinic setting with the surgeon was preferred globally.

The purpose of this study was to estimate health care resource utilization and costs among COPD patients with newly acquired pneumonia compared to those without pneumonia. Methods: A retrospective claims analysis using Truven MarketScan® Commercial and Medicare databases was conducted. COPD patients with and without newly acquired pneumonia diagnosed between January 1, 2004 and September 30, 2011 were identified. Propensity score matching was used to create a 1:1 matched cohort. Patient demographics, comorbidities (measured by Charlson Comorbidity Index, and medication use were evaluated before and after matching. Health care resource utilization (ie, hospitalizations, emergency room [ER] and outpatient visits, and associated health care costs were assessed during the 12-month follow-up. Logistic regression was conducted to evaluate the risk of hospitalization and ER visits, and gamma regression models and two-part models compared health care costs between groups after matching. Results: In the baseline cohort (N=467,578, patients with newly acquired pneumonia were older (mean age: 70 versus [vs] 63 years and had higher Charlson Comorbidity Index scores (3.3 vs 2.6 than patients without pneumonia.

    To ascertain the causative organisms of community acquired pneumonia (Cap) in Jordanian patients requiring hospital admission. A prospective study of both adults and children admitted to Princess Basma and Princess Rahma Teaching Hospitals in Irbid, Jordan with a diagnosis of CAP over a 6-month period from April to October 2002. A total of 35 adult patients were admitted with a mean age of 47 years, and 63 children with a mean age of 3 years. A pathogen was isolated from 25 (71%) adults, and from 17 (27%) children, and sputum cultures gave the best diagnostic yield. In adults Streptococcus pneumoniae was the most common isolate (26%), followed by Chlamydia pneumoniae (23%), Haemophilus influenzae (17%), Mycoplasma pneumoniae (9%), and Legionella pneumophila and Klebsiella pneumoniae (6%) each. Seven of the 9 gram negative isolates were from patients with some co morbid illness. While in children, Chlamydia pneumoniae was the most common (14%), followed by Mycoplasma pneumoniae (6%), and Streptococcus pneumoniae, Haemophilus influenzae, and Pseudomonas aeruginosa (3%) each. Streptococcus pneumoniae and atypical microorganisms are the most common cause of CAP in previously healthy adults; while in those with associated co morbid illness, gram negative organisms are the likely cause. In children, the overall detection rate of causative organisms was low with atypical microorganisms being the most common. (author)

    Defining health care-associated pneumonia, which includes both hospital-acquired pneumonia (HAP) and ventilator-associated pneumonia (VAP), is problematic and controversial. Aspiration pneumonia is often included as a subtype of HAP but may be related to community-acquired aspiration events. Scoring systems exist and new surveillance guidelines have been implemented to make early recognition of pneumonia more precise and objective. Management and prevention should follow recommendations, including early empirical therapy, targeted therapy, and limited duration of treatment. Patients with trauma present a challenge to the diagnosis and management of pneumonia, because of increased risk for aspiration and underlying chest and pulmonary injury.

    We wanted to demonstrate and compare the serial high-resolution CTs (HRCT) and the pulmonary function test (PFT) findings of the usual interstitial pneumonia (UIP) and the non-specific interstitial pneumonia (NSIP). The serial HRCT scans and the PFT results were retrospectively analysed and compared for 35 patients having UIP without significant honeycombing (UIP-w/o hc, < 5% of honeycombing at CT), 35 patients having UIP with honeycombing (UIP-w/i hc, {>=} 5% of honeycombing), and 25 patients with NSIP. The mortality rates were also compared. Follow-up CT scans were available in 75 patients (29 UIP-w/o hc patients, 22 UIP-w/i hc patients and 24 NSIP patients) and the follow-up periods ranged from 150 to 2,370 days. The initial and follow-up PFT data were available for 71 patients. On the initial CT, significant differences were present between the UIP-w/i hc patients and both the UIP-w/o hc patients and the NSIP patients in the overall extent, ground-glass opacity (GGO) away from the reticulation, reticulation and honeycombing (all {rho} < 0.05). Improvement was noticed in five (17%) of 29 UIP-w/o hc patients, none of 22 UIP-w/i hc patients, and 9 (37%) of 24 NSIP patients; deterioration was noted in six (21%) UIP-w/o hc patients, two (9%) UIP-w/i hc patients and three (13%) NSIP patients ({rho} 0.044 between UIP-w/o and UIP-w/i hc; {rho} = 0.637 between UIP-w/o hc and NSIP; {rho} = 0.007 between UIP-w/i hc and NSIP). The serial changes of the pulmonary function in the NSIP patients were different from those noted for the UIP-w/i hc and UIP-w/o hc patients ({rho} = 0.440 between UIP-w/o and UIP-w/i hc; {rho} = 0.022 between UIP-w/o hc and NSIP; {rho} =0.003 between UIP-w/i hc and NSIP). Five (14%) of the 35 patients with UIP-w/o hc, 16 (46%) of the 35 patients with UIP-w/i hc and three (12%) of the 25 patients with NSIP died ({rho} = 0.002, comparison for the three groups). On CT, NSIP and UIP-w/o hc patients have similar patterns of parenchymal abnormalities and

    Objective: To explore the imaging features on chest radiograph and CT in children with Influenza A H1N1 pneumonia. Methods: The imaging data of chest radiograph and CT in six children with Influenza A H1N1 pneumonia confirmed by real-time RT-PCR assay was retrospectively analysis. All patients had chest radiograph at first examination and 4 of them re-examed. One children took CT. Results: All cases showed thick lung markings with varied degrees of pulmonary infiltration and interstitial changes on chest radiograph. Among them, 3 cases showed bilateral pulmonary infiltration and 3 cases showed infiltration in left lung; enlarged hilar was observed in 3 cases. The imaging findings of the pneumonia changed quickly during the follow-up accompanied with the improvement of clinical symptoms. The only one chest CT examination showed bilateral infiltration, multiple ground-glass opacities, small subpleural nodulars, right pleural effusion and lymphadenopathy of lung hila and mediastinum. Conclusions: Chest radiograph and CT revealed certain typical imaging features in the children with influenza A H1N1 pneumonia. However, the final diagnosis of influenza A H1N1 pneumonia still should be made based on epidemiology and laboratory examination. (authors)

    Subtotal adrenalectomy was given to 10 adult patients with Cushing's disease, concurrently with or following therapeutic regimen by long term reserpine administration and pituitary irradiation. In the present study, we describe long term follow-up results. Two patients died after the operation due to acute adrenal crisis and pneumonia, respectively. The other 8 patients achieved clinical and biochemical remissions and were followed for long term. Three patients relapsed 9, 14 or 17 years after achieving remission, two patients developed hypopituitarism 12 or 20 years after and one died of cerebral vascular accident at 64 years, 5 years after the remission. The remaining 2 patients maintained remission for 10 or 18 years, respectively. During the remission periods of 0.5 to 20 years with a mean of 10.1±6.7 years, 6 of 7 patients examined by 1 mg overnight dexamethasone test showed normal suppressibility of plasma cortisol. Provocative tests of plasma GH by 1-arginine infusion and/or insulin-induced hypoglycemia were performed in 6 patients in the early remission period. All of 5 patients in the arginine infusion test and 3 of 5 in the insulin-induced hypoglycemia test showed normal responses. Furthermore, to facilitate prediction of long term response or failure to our therapeutic regimen, long term reserpine administration and pituitary irradiation, pretreatment clinical and biochemical characteristics were analyzed retrospectively in 3 divided groups; the present 10 patients treated with reserpine and pituitary irradiation followed by subtotal adrenalectomy, 11 patients achieving long term remission treated by our regimen alone, and 7 patients failed with our regimen alone. There were no significant factors predictive of response to our regimen. (author)

    A study of 31 patients operated on for rectal neoplasms between September, 1989 and September, 1995 in SantiAug de Cuba was performed. Patients Webre followed-up during this period for the purpose of the study. There was a frank predominance of males and ages between 45 and 64, of the stage II and the groups BI and BII according to Dukes' classification. Most patients received 5-fluoracil, without tumor relapses. The current survival rate of the series was 76 % at the end of the investigation. It is recommended that all patients operated on for this segment be followed-up after the operation; to continue with cytostatic treatment using 5-fluoracil, and to emphasize the importance of the use of tumor markers during the follow-up, in addition to transrectal ultrasound, as well as to make an early diagnosis through mass screening methods

    Background: Four million people die each year from diseases caused by exposure to household air pollution. There is an association between exposure to household air pollution and pneumonia in children (half a million attributable deaths a year); however, whether this is true in adults is unknown. We conducted a case-control study in urban Malawi to examine the association between exposure to household air pollution and pneumonia in adults. Methods: Hospitalized patients with radiologically confirmed pneumonia (cases) and healthy community controls underwent 48 hours of ambulatory and household particulate matter (µg/m 3 ) and carbon monoxide (ppm) exposure monitoring. Multivariate logistic regression, stratified by HIV status, explored associations between these and other potential risk factors with pneumonia. Results: 145 (117 HIV-positive; 28 HIV-negative) cases and 253 (169 HIV-positive; 84 HIV-negative) controls completed follow up. We found no evidence of association between household air pollution exposure and pneumonia in HIV-positive (e.g. ambulatory particulate matter adjusted odds ratio [aOR] 1.00 [95% CI 1.00-1.01, p=0.141]) or HIV-negative (e.g. ambulatory particulate matter aOR 1.00 [95% CI 0.99-1.01, p=0.872]) participants. Chronic respiratory disease was associated with pneumonia in both HIV-positive (aOR 28.07 [95% CI 9.29-84.83, ppollution is associated with pneumonia in Malawian adults. In contrast, chronic respiratory disease was strongly associated with pneumonia.

    Studies have linked the use of inhaled corticosteroids (ICSs) to excess pneumonia risk in chronic obstructive pulmonary disease patients. The risk in asthma patients remains unclear. The objective of the present study was to examine the risk of pneumonia with ICSs in asthma patients aged 12-35 years. We formed a cohort of asthma patients treated from 1990 to 2007 using Quebec health insurance databases. Subjects were considered currently exposed if they had had an ICS dispensed within the 60 days prior to their pneumonia index event or matched person-moment. Secondary analyses investigated the risk of pneumonia according to ICS dose and type. Rate ratios (RRs) and rate differences (RDs) were both estimated through a quasi-cohort approach. The cohort included 152 412 subjects, of whom 1928 had a pneumonia event during follow-up. There was an increased risk of pneumonia associated with current use of ICSs [RR 1.83; 95% confidence interval (CI) 1.57, 2.14] or an excess risk of 1.44 cases per 1000 person-years (RD 1.44; 95% CI 1.03, 1.85). There was an excess pneumonia risk with low doses (RR 1.60; 95% CI 1.06, 2.45), moderate doses (RR 1.53; 95% CI 1.12, 2.08) and high doses (RR 1.96; 95% CI 1.64, 2.34) of ICSs, and with budesonide (RR 2.67; 95% CI 2.05, 3.49) and fluticasone (RR 1.93; 95% CI 1.58, 2.36), specifically relative to no use. When accounting for potential protopathic bias, the risk with current use of ICSs was attenuated (RR 1.48; 95% CI 1.22, 1.78). ICS use in asthma patients appears to be associated with an increased risk of pneumonia and is present for both budesonide and fluticasone. © 2017 The British Pharmacological Society.

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

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

    The authors describe a case of 51-year-old woman who presented with breathlessness following radiotherapy for breast carcinoma. A chest radiograph and thoracic CT scan revealed extensive airspace consolidation affecting right upper and lower lobes. A trans-bronchial biopsy revealed evidence of foamy macrophages and fibroblastic plugs within alveoli, consistent with organising pneumonia. Indirect immunofluorescence microscopy revealed evidence of antiepithelial antibodies. Gradual but complete resolution occurred without any specific treatment. This case highlights the importance of considering radiation induced bronchiolitis obliterans organising pneumonia in the context of parenchymal shadowing following radiotherapy. Although corticosteroids are widely recommended for treatment, this case illustrates that organising pneumonia may resolve spontaneously.

    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

    Full Text Available Mycoplasma pneumoniae is an atypical bacterium that most commonly causes upper respiratory tract infections, but it can also cause pneumonia, referred to as “walking pneumonia.” Although cavitary lesions are present in a wide variety of infectious and noninfectious processes, those attributable to M. pneumoniae are extremely uncommon; thus, to date, epidemiological studies are lacking. Here, we present a rare case of a 20-year-old male, referred to us from a psychiatric facility for evaluation of a cough, who was found to have a cavitary lesion in the right upper lobe. An extensive workup for cavitary lesion was negative, but his mycoplasma IgM level was high. A computed tomography (CT of the chest confirmed the presence of a cavitary lesion. After treatment with levofloxacin antibiotics, a follow-up CT showed complete resolution of the lesion. Our case is a rare presentation of mycoplasma pneumonia as a cavitary lesion in a patient without any known risk factors predisposing to mycoplasma infection. Early recognition and treatment with an appropriate antibiotic may lead to complete resolution of the cavitary lesion.

    Idiopathic interstitial pneumonias are at present classified as one of four types: usual, nonspecific, acute, or desquamative. The acute form has the worst prognosis, followed by the usual and the nonspecific form; it is in desquamative cases that prognosis is best. At high-resolution CT, usual interstitial pneumonia, the most frequent type, manifests as patchy subpleural areas of ground-glass attenuation, irregular linear opacity, and honeycombing, which the nonspecific type, the second most frequent, appears as subpleural patchy areas of ground-glass attenuation with associated areas of irregular linear opacity. Acute interstitial pneumonia demonstrates extensive bilateral airspace consolidation and patchy or diffuse bilateral areas of ground-glass attenuation in middle and lower lung zones

    A 4-year-old female alpaca was referred to The Queen's Veterinary School Hospital (Cambridge, United Kingdom) with a history of abortion 6 days previous, at approximately 245 days in gestation. The patient had developed watery diarrhea 24 hr after abortion and exhibited bruxism, progressive depression, and ultimately collapse. On presentation to the referral institute, the alpaca was unable to stand and exhibited severe tachypnea, dyspnea, and tachycardia. The patient was considered to be moribund and was euthanized. Macroscopic postmortem assessment and subsequent histological investigations revealed multifocal ulceration of the third gastric compartment, with vascular mycotic invasion and disseminated multifocal embolic mycotic pneumonia. Real-time polymerase chain reaction targeting the large ribosomal subunit (28S) performed on paraffin-embedded lung tissue successfully amplified 28S RNA specific for Aspergillus species. The primary cause of the depression and collapse of this animal was considered to be a combination of respiratory compromise due to severe embolic mycotic pneumonia and endotoxic shock associated with the ulcerative gastritis of the third gastric compartment. To the authors' knowledge, this is the first report of ulcerative gastritis of the third gastric compartment histologically illustrated as a portal of entry for Aspergillus species causing embolic mycotic pneumonia in an alpaca.

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

    A stationary association between climate factors and epidemics of Mycoplasma pneumoniae (M. pneumoniae) pneumonia has been widely assumed. However, it is unclear whether elements of the local climate that are relevant to M. pneumoniae pneumonia transmission have stationary signatures of climate factors on their dynamics over different time scales. We performed a cross-wavelet coherency analysis to assess the patterns of association between monthly M. pneumoniae cases in Fukuoka, Japan, from 2000 to 2012 and indices for the Indian Ocean Dipole (IOD) and El Niño Southern Oscillation (ENSO). Monthly M. pneumoniae cases were strongly associated with the dynamics of both the IOD and ENSO for the 1-2-year periodic mode in 2005-2007 and 2010-2011. This association was non-stationary and appeared to have a major influence on the synchrony of M. pneumoniae epidemics. Our results call for the consideration of non-stationary, possibly non-linear, patterns of association between M. pneumoniae cases and climatic factors in early warning systems.

    Objective: To evaluate the efficacy and safety of emergency transcatheter occlusion of patent ductus arteriosus associated with severe pneumonia in infants. Methods: During the period from Oct. 2011 to May 2012, 12 infants with patent ductus arteriosus complicated by severe pneumonia were admitted to the hospital. The infants had repeated episodes of pneumonia together with heart failure. Emergency transcatheter occlusion of patent ductus arteriosus was carried out in all infants. After the treatment the use of anti-bacterial drugs and cardiac stimulants was kept on. Routine examinations of blood and urine were made 24 hours after the management. Two-dimensional and color Doppler echocardiography, chest radiograph and electrocardiogram were performed at 24 hours, 1, 3, and 6 months after the surgery. The results were analyzed. Results: After emergency transcatheter closure, all patients recovered fully at the time of discharge. No intervention-related major complications occurred during short-term follow-up period. Conclusion: For the treatment of patent ductus arteriosus associated with severe pneumonia in infants, emergency transcatheter occlusion therapy is effective and safe. Optimal surgery time together with proper perioperative management is the key to ensure a successful operation. (authors)

    The radiographic findings in the acute phase of Legionella pneumonia are generally non-specific and have been previously documented. A retrospective assessment of 12 patients with this bacterial pneumonia revealed that resolution of the radiographic findings was prolonged in five. The predominant feature in such patients is the transient finding of interstitial consolidation following the air-space consolidation, not unlike that of Mycoplasma or viral pneumonia. Eventual return to normal was evident in three patients and residual parenchymal fibrosis was noted in two patients.

    To analyze the usefulness and ability of procalcitonin (PCT) to predict the presence of bacteremia in patients with community-acquired pneumonia (CAP) caused by Streptococcus pneumoniae (S. pneumoniae) or other bacteria. This is an observational, prospective and descriptive study involving patients who were diagnosed with CAP in our Emergency Department. Data collected included socio-demographic and comorbidity variables, Charlson index, stage in the Pneumonia Severity Index and criteria of severe NAC, microbiologic studies and biomarker determinations (PCT and C reactive protein). The follow-up was carried out during 30 days to calculate the predictive power and the diagnostic performance for bacteremia caused or not by S. pneumoniae. Four hundred and seventy-four patients were finally included in the study. Blood cultures were positive in 85 individuals (17.9%) and S. pneumoniae was identified as the responsible pathogen in 75 of them (88.4%) (in 5 cases together with another agent). The area under the Receiver Operating Characteristic curve for PCT to predict bacteremia (caused by S. pneumoniae or not) was 0.988 (95% confidence interval 0.908-0.995; P98% and>10, respectively. The most frequently isolated serotypes of S. pneumoniae were 19A, 7F, 1 and 3. The highest mean levels of PCT were found in serotypes 7F, 19A, 3 and 1, which showed statistically significant differences with regard to the others serotypes considered (P=.008). Serotypes associated with the highest percentage of severe sepsis-septic shock, 30-days mortality and multi-lobe or bilateral affection were 3, 1 and 19A; 1, 3 and 19A; and 3, 19A and 6A, respectively. PCT had a remarkable diagnostic ability to discard or suspect bacteremia and to guide the etiology of CAP caused by S. pneumoniae. Serotypes 1, 3, 19A and 7F showed greater frequency, systemic inflammatory response and clinical severity. Copyright © 2013 Elsevier España, S.L. All rights reserved.

    Thomas E Besser

    Full Text Available Bronchopneumonia is a population limiting disease of bighorn sheep (Ovis canadensis. The cause of this disease has been a subject of debate. Leukotoxin expressing Mannheimia haemolytica and Bibersteinia trehalosi produce acute pneumonia after experimental challenge but are infrequently isolated from animals in natural outbreaks. Mycoplasma ovipneumoniae, epidemiologically implicated in naturally occurring outbreaks, has received little experimental evaluation as a primary agent of bighorn sheep pneumonia.In two experiments, bighorn sheep housed in multiple pens 7.6 to 12 m apart were exposed to M. ovipneumoniae by introduction of a single infected or challenged animal to a single pen. Respiratory disease was monitored by observation of clinical signs and confirmed by necropsy. Bacterial involvement in the pneumonic lungs was evaluated by conventional aerobic bacteriology and by culture-independent methods. In both experiments the challenge strain of M. ovipneumoniae was transmitted to all animals both within and between pens and all infected bighorn sheep developed bronchopneumonia. In six bighorn sheep in which the disease was allowed to run its course, three died with bronchopneumonia 34, 65, and 109 days after M. ovipneumoniae introduction. Diverse bacterial populations, predominantly including multiple obligate anaerobic species, were present in pneumonic lung tissues at necropsy.Exposure to a single M. ovipneumoniae infected animal resulted in transmission of infection to all bighorn sheep both within the pen and in adjacent pens, and all infected sheep developed bronchopneumonia. The epidemiologic, pathologic and microbiologic findings in these experimental animals resembled those seen in naturally occurring pneumonia outbreaks in free ranging bighorn sheep.

In both experiments the challenge strain of M. ovipneumoniae was transmitted to all animals both within and between pens and all infected bighorn sheep developed bronchopneumonia. In six bighorn sheep in which the disease was allowed to run its course, three died with bronchopneumonia 34, 65, and 109 days after M. ovipneumoniae introduction. Diverse bacterial populations, predominantly including multiple obligate anaerobic species, were present in pneumonic lung tissues at necropsy. Exposure to a single M. ovipneumoniae infected animal resulted in transmission of infection to all bighorn sheep both within the pen and in adjacent pens, and all infected sheep developed bronchopneumonia. The epidemiologic, pathologic and microbiologic findings in these experimental animals resembled those seen in naturally occurring pneumonia outbreaks in free ranging bighorn sheep.

    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.

    Full Text Available BACKGROUND: A stationary association between climate factors and epidemics of Mycoplasma pneumoniae (M. pneumoniae pneumonia has been widely assumed. However, it is unclear whether elements of the local climate that are relevant to M. pneumoniae pneumonia transmission have stationary signatures of climate factors on their dynamics over different time scales. METHODS: We performed a cross-wavelet coherency analysis to assess the patterns of association between monthly M. pneumoniae cases in Fukuoka, Japan, from 2000 to 2012 and indices for the Indian Ocean Dipole (IOD and El Niño Southern Oscillation (ENSO. RESULTS: Monthly M. pneumoniae cases were strongly associated with the dynamics of both the IOD and ENSO for the 1-2-year periodic mode in 2005-2007 and 2010-2011. This association was non-stationary and appeared to have a major influence on the synchrony of M. pneumoniae epidemics. CONCLUSIONS: Our results call for the consideration of non-stationary, possibly non-linear, patterns of association between M. pneumoniae cases and climatic factors in early warning systems.

    Full Text Available Streptococcus pneumoniae is an uncommon etiologic organism in children with hemolytic uremic syndrome (HUS. Historically, severe S. pneumoniae-associated HUS usually has a poor clinical outcome. The clinical manifestations of marked jaundice and hepatic dysfunction in this form of HUS are extremely rare. We report a 10-month-old female infant with S. pneumoniae-associated HUS who had the unusual manifestation of severely elevated conjugated bilirubin and hepatic transaminases. Screening for viral hepatitis was negative, and evidence of biliary obstruction and hepatotoxic drug exposure was also absent. The patient was treated with antihypertensive agents for 2.5 months and required peritoneal dialysis for a period of 26 days. Hepatic function returned to normal on the 8th day of hospitalization. Renal function was mildly impaired at 1-year follow-up. Our report suggests that severe conjugated hyperbilirubinemia is a rare manifestation of S. pneumoniae-associated HUS in children. It is important for pediatricians that pneumococcal infection with severe hematologic and renal disorders should be investigated for evidence of S. pneumoniae-associated HUS.

    Idiopathic interstitial pneumonias (IIP) comprise seven entities with distinct histologic patterns. In their idiopathic form IIP are rare diseases. They are, nevertheless, considered prototypes of the much more common secondary interstitial pneumonias. The advent of high-resolution computed tomography (HRCT) has had a profound impact on the imaging of IIP, because the detailed delineation of the lung anatomy allows a close correlation between the histologic patterns of IIP and the CT features. On the basis of CT morphology and in the correct clinical context, the radiologist can achieve an accurate diagnosis in many cases. However, due to overlap between the various entities, complementary lung biopsy is recommended in virtually all cases. This article reviews the CT pattern of IIP and offers relevant clinical and histological information for the purpose of enabling the radiologist to understand and participate in the multidisciplinary concept of IIP. (orig.) [German] Die Bezeichnung idiopathische interstitielle Pneumonien (IIP) umfasst 7 Entitaeten mit definierten histologischen Mustern. In ihrer idiopathischen Form sind die interstitiellen Pneumonien selten, allerdings werden die einzelnen Muster als Prototypen fuer die haeufigeren sekundaeren interstitiellen Pneumonien betrachtet. Mit der Einfuehrung der hochaufloesenden Computertomographie (HRCT) hat die Bildgebung der IIP einen deutlichen Aufschwung erfahren, da durch die detaillierte Darstellung der Lungenanatomie eine sehr gute Korrelation zwischen den histologischen Mustern der IIP und den CT-Veraenderungen gegeben ist. Der Radiologe kann anhand der CT-Morphologie und unter Beruecksichtigung der Klinik des Patienten in vielen Faellen eine korrekte Diagnose erstellen. Dennoch wird aufgrund von Ueberlappungen zwischen den verschiedenen Entitaeten bei nahezu allen Formen der IIP eine ergaenzende Lungenbiopsie empfohlen.

    To assess the quality and safety of having community health workers (CHWs) in rural Zambia use rapid diagnostic tests (RDTs) and provide integrated management of malaria and pneumonia. In the context of a cluster-randomized controlled trial of two models for community-based management of malaria and/or non-severe pneumonia in children under 5 years old, CHWs in the intervention arm were trained to use RDTs, follow a simple algorithm for classification and treat malaria with artemether-lumefantrine (AL) and pneumonia with amoxicillin. CHW records were reviewed to assess the ability of the CHWs to appropriately classify and treat malaria and pneumonia, and account for supplies. Patients were also followed up to assess treatment safety. During the 12-month study, the CHWs evaluated 1017 children with fever and/or fast/difficult breathing and performed 975 RDTs. Malaria and/or pneumonia were appropriately classified 94-100% of the time. Treatment based on disease classification was correct in 94-100% of episodes. Supply management was excellent with over 98% of RDTs, amoxicillin, and AL properly accounted for. The use of RDTs, amoxicillin, and AL was associated with few minor adverse events. Most febrile children (90%) with negative RDT results recovered after being treated with an antipyretic alone. Volunteer CHWs in rural Zambia are capable of providing integrated management of malaria and pneumonia to children safely and at high quality.

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

    Exogenous lipoid pneumonia is a rare disorder caused by aspiration of mineral, vegetable and animal oils. High-resolution CT findings of lipoid pneumonia in children taking mineral oil for constipation have been rarely reported. To evaluate the high-resolution CT findings in 17 children with exogenous lipoid pneumonia following aspiration of mineral oil. The study included nine boys and eight girls, with ages ranging from 2 months to 9 years. All patients underwent high-resolution CT and the images were reviewed by two radiologists who reached decisions by consensus. The inclusion criteria were an abnormal radiograph, history of taking mineral oil and the presence of intrapulmonary lipids proved by bronchoalveolar lavage or open lung biopsy. The most common symptoms were cough (n = 13), mild fever (n = 11), and progressive dyspnea (n = 9). The main CT findings were air-space consolidations (100%), usually with areas of fatty attenuation (70.6%), areas of ground-glass attenuation (52.9%), and a crazy-paving pattern (17.6%), predominating bilaterally in the posterior and lower regions of the lungs. The high-resolution CT features in children with exogenous lipoid pneumonia are air-space consolidations and ground-glass attenuation, occasionally with a crazy-paving pattern, distributed bilaterally in the posterior and lower zones of the lungs.

    To describe the correlation between the functional dysphagia scale and aspiration pneumonia and which characteristics influence the occurrence of aspiration pneumonia in patients with idiopathic Parkinson disease. Fifty-three patients with idiopathic Parkinson disease were prospectively evaluated in this study. Disease severity and functional status were measured by modified Hoehn and Yahr (H&Y) staging, Schwab and England activities of daily living (S-E ADL) scale and Korean version of Mini-Mental State Examination (K-MMSE). Swallowing function was evaluated by the functional dysphagia scale (FDS) and the penetration-aspiration scale (PAS) based on a videofluoroscopic swallowing study. The patients were followed up for 3 months and divided into two groups according to the occurrence of aspiration pneumonia. The correlation between the variables and aspiration pneumonia was analyzed. Eight patients of the 53 patients were allocated to the aspiration pneumonia group and 45 patients to the non-aspiration pneumonia group. The patients in the aspiration pneumonia group had significantly higher H&Y staging, and scored lower on S-E ADL scale and K-MMSE. The patients in the aspiration pneumonia group had significantly higher scores on FDS and PAS. A multiple logistic regression analysis showed that the S-E ADL scale and the FDS were associated with the occurrence of aspiration pneumonia in the patients with Parkinson disease. Given that the FDS can quantitatively assess the functional problems associated with dysphagia, it can be clinically effective in predicting the occurrence of aspiration pneumonia, and the FDS and the S-E ADL scale could be predictive variables for aspiration pneumonia in patients with Parkinson disease.

    Using an objective scoring system, chest radiographs were reviewed in 23 cases of pneumonia due to the Pittsburgh pneumonia agent (PPA, Tatlockia micdadei, Legionella micdadei), including six cases of pneumonia with simultaneous isolation of PPA and L pneumophila (Legionnaires' disease). Infiltrates were typically segmental to lobar; nodular infiltrates were noted in three cases. Spread to additional lobes after presentation occurred in four of 17 PPA infections. Pneumonia caused by both PPA and L pneumophila was unusually severe, with involvement of all lobes occurring in four of six cases, compared with one of 17 cases of PPA infection (p>0.02). Radiographic severity did not correlate with underlying disease, immune status, or outcome. The majority of patients receiving erythromycin demonstrated objective radiologic improvement. In a patients, population that included nonimmunosuppressed patient, nodule formation and rapid radiologic progression were not found to be characteristic of PPA pneumonia

Follow-up was successfully completed in 14 of 17 patients. 4 patients at time point 3, 2 patients at time point 4, 3 patients at time point 5 and 2 patients at time point 6 and time point 7 used continuous pain medication after endoscopic therapy. No relapse occurred in 57% (8/14) of patients. All 8 patients exhibited significantly reduced or no pain complaints during the 5-year follow-up. Seven of 8 patients were completely pain free 5 years after endoscopic therapy. Only 1 patient reported continuous moderate pain. In contrast, 7 relapses occurred in 6 of the 14 patients. Two relapses were observed during the 1(st) year, 2 relapses occurred during the 2(nd) year, one relapse was observed during the 3(rd) year, one relapse occurred during the 4(th) year, and one relapse occurred during the 5(th) follow-up year. Four of these six patients received conservative treatment with endoscopic therapy or analgesics. Relapse was conservatively treated using repeated stent therapy in 2 patients. Analgesic treatment was successful in the other 2 patients. 57% of patients exhibited long-term benefits after endoscopic therapy. Therefore, endoscopic therapy should be the treatment of choice in patients being inoperable or refusing surgical treatment.

  18. Specificity and Strain-Typing Capabilities of Nanorod Array-Surface Enhanced Raman Spectroscopy for Mycoplasma pneumoniae Detection.

    Full Text Available Mycoplasma pneumoniae is a cell wall-less bacterial pathogen of the human respiratory tract that accounts for > 20% of all community-acquired pneumonia (CAP. At present the most effective means for detection and strain-typing is quantitative polymerase chain reaction (qPCR, which can exhibit excellent sensitivity and specificity but requires separate tests for detection and genotyping, lacks standardization between available tests and between labs, and has limited practicality for widespread, point-of-care use. We have developed and previously described a silver nanorod array-surface enhanced Raman Spectroscopy (NA-SERS biosensing platform capable of detecting M. pneumoniae with statistically significant specificity and sensitivity in simulated and true clinical throat swab samples, and the ability to distinguish between reference strains of the two main genotypes of M. pneumoniae. Furthermore, we have established a qualitative lower endpoint of detection for NA-SERS of < 1 genome equivalent (cell/μl and a quantitative multivariate detection limit of 5.3 ± 1 cells/μl. Here we demonstrate using partial least squares- discriminatory analysis (PLS-DA of sample spectra that NA-SERS correctly identified M. pneumoniae clinical isolates from globally diverse origins and distinguished these from a panel of 12 other human commensal and pathogenic mycoplasma species with 100% cross-validated statistical accuracy. Furthermore, PLS-DA correctly classified by strain type all 30 clinical isolates with 96% cross-validated accuracy for type 1 strains, 98% cross-validated accuracy for type 2 strains, and 90% cross-validated accuracy for type 2V strains.

    Childhood pneumonia is one of the leading single causes of mortality and morbidity in children worldwide, but its etiology still remains unclear. We investigate the association between childhood pneumonia and exposure to diurnal temperature variation (DTV) in different timing windows. We conducted a prospective cohort study of 2,598 children aged 3-6 years in Changsha, China. The lifetime prevalence of pneumonia was assessed by a questionnaire administered by the parents. Individual exposure to DTV during both prenatal and postnatal periods was estimated. Logic regression models was used to examine the association between childhood pneumonia and DTV exposure in terms of odds ratios (OR) and 95% confidence interval (CI). Lifetime prevalence of childhood pneumonia in preschool children in Changsha was high up to 38.6%. We found that childhood pneumonia was significantly associated with prenatal DTV exposure, with adjusted OR (95%CI) =1.19 (1.02-1.38), particularly during the second trimester. However, childhood pneumonia not associated with postnatal DTV exposure. Sensitivity analysis indicated that boys are more susceptible to the pneumonia risk of diurnal temperature variation than girls. We further observed that the prevalence of childhood pneumonia was decreased in recent years as DTV shrinked. Early childhood pneumonia was associated with prenatal exposure to the diurnal temperature variation (DTV) during pregnancy, particularly in the second trimester, which suggests fetal origin of childhood pneumonia.

    One of the strategies for the rational use of antibiotics is the use of the score for community-acquired pneumonia (CAP Score). This instrument clinically evaluates patients with community-acquired pneumonia, thereby facilitating decision making regarding the early and safe withdrawal of antibiotics. To generate a translation and cross-cultural adaptation of the Community-Acquired Pneumonia (CAP) Score questionnaire in Spanish. Authorization for cross-cultural adaptation of the Community-Acquired Pneumonia (CAP) Score questionnaire was obtained; the recommendations of the International Society for Pharmacoeconomics and Outcomes Research (ISPOR) and the European Organisation for Research and Treatment of Cancer (EORTC) were carried out through the following stages: forward translation, reconciliation, backward translation, harmonization, obtaining a provisional questionnaire, and applying the questionnaire in a pilot test. The pilot test was conducted at a second-level public hospital in Bogotá after the study was approved by the ethics and research institutional boards. The changes suggested by the forward translators were applied. There were no discrepancies between the backward and forward translations, consequently, no revisions were necessary. Five items had modifications based on suggestions made by eleven patients hospitalized with a diagnosis of community-acquired pneumonia during the pilot test. A Spanish version of the Community-Acquired Pneumonia (CAP) Score was crossculturally adapted and is now available.

    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 The follow-up time was investigated. The aim of this analysis was to create a formula that allows the follow-up time calculated using the most important external parameters. The studies were based on empirical data collected at small roundabouts localized on Upper Silesia. The follow-up time is the average time gap between two cars of the minor stream being queued and entered the same major stream gap one behind the other. Follow-up times were measured directly by observing traffic flow. Resulting follow-up times were analyzed to determine their dependence on parameters such as intersection layout, roundabouts diameter and left visibility. These parameters were tested using the conventional calculation method (regression analysis. The dependence of follow-up time was then integrated into the own capacity estimation method for small roundabouts localized on urban areas. One of the biggest advantages this dependence is that capacity and traffic flow on small roundabouts can be determined reliably and appropriately for actual situations. The new follow-up time values for all range of external diameters of small roundabout 26 (22 – 40 m have been presented in this article.

    Full Text Available Background Bacteremia in children with pneumonia reflects a severe condition, with longer duration of hospital care and potentially lethal complications. Early detection of bacteremia in patients with pneumonia may reduce serious complications. Few bacteremia screening tools have been widely used in chidren with pneumonia. One of those tools is the bacterial pneumonia score (BPS. Objective To assess the validity of the bacterial pneumonia score for predicting bacteremia in pediatric patients with pneumonia. Methods A diagnostic test was conducted on children aged 1 to 60 months hospitalized with pneumonia from December 2009 to August 2010. Subjects were collected consecutively. Pneumonia was diagnosed using the World Healt Organization (WHO criteria. Subjects underwent complete blood counts and blood culture examinations at admission. Statistical analyses included sensitivity, specificity, positive and negative predictive value (PPV/NPV, positive and negative likelihood ratio (PLR/NLR, and post-test probability. Results Our study included 229 children. Based on BPS with a cut-off score of ≥ 4, the sensitivity was 83.3%, specificity 49.7%, PPV 8.4%, NPV 98.2%, PLR 1.66, NLR 0.31, and post-test probability 8.4% for detecting bacteremia in pediatric pneumonia patients. Conclusion BPS can not be used for predicting bacteremia in pediatric patients with pneumonia.

    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. 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. 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). 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.

  14. Chlamydia pneumoniae hides inside apoptotic neutrophils to silently infect and propagate in macrophages.

    Directory of Open Access Journals (Sweden)

    Jan Rupp

    Full Text Available BACKGROUND: Intracellular pathogens have developed elaborate strategies for silent infection of preferred host cells. Chlamydia pneumoniae is a common pathogen in acute infections of the respiratory tract (e.g. pneumonia and associated with chronic lung sequelae in adults and children. Within the lung, alveolar macrophages and polymorph nuclear neutrophils (PMN are the first line of defense against bacteria, but also preferred host phagocytes of chlamydiae. METHODOLOGY/PRINCIPAL FINDINGS: We could show that C. pneumoniae easily infect and hide inside neutrophil granulocytes until these cells become apoptotic and are subsequently taken up by macrophages. C. pneumoniae infection of macrophages via apoptotic PMN results in enhanced replicative activity of chlamydiae when compared to direct infection of macrophages, which results in persistence of the pathogen. Inhibition of the apoptotic recognition of C. pneumoniae infected PMN using PS- masking Annexin A5 significantly lowered the transmission of chlamydial infection to macrophages. Transfer of apoptotic C. pneumoniae infected PMN to macrophages resulted in an increased TGF-ss production, whereas direct infection of macrophages with chlamydiae was characterized by an enhanced TNF-alpha response. CONCLUSIONS/SIGNIFICANCE: Taken together, our data suggest that C. pneumoniae uses neutrophil granulocytes to be silently taken up by long-lived macrophages, which allows for efficient propagation and immune protection within the human host.

    The diagnosis of squalene aspiration pneumonia in children is often difficult because of minimal non-specific symptoms. To investigate the radiological findings of squalene aspiration pneumonia in children. We reviewed the chest radiographs (n=8) and CT scans (n=), including high-resolution CT (n=3), of eight patients (four boys, four girls; age 3 months to 6 years) with squalene aspiration pneumonia. All patients presented minimal symptoms. Chest radiographs showed right-sided predominantly parahilar infiltrations. The extent and the opacity of the lesions decreased slowly during the follow-up period (mean 5.4 months) after halting the exposure. On CT, affected areas appeared as dense consolidations surrounded by ground-glass opacities showing a crazy-paving pattern in a geographic lobular distribution in all patients. The lesions were predominantly in the right lung and dependent areas in all patients and extensively involved all pulmonary lobes in five patients. These radiological findings, although non-specific, can lead to an appropriate diagnosis, particularly when patients present few symptoms. (orig.)

    Full Text Available Here, we report a case of 57-year-old previously healthy man with six-months medical history of significant chronic cough and recurring episodes of fever. Cytology, bacteria, fungi and acid fast bacilli in the sputum were negative. CT scan, initially interpreted as suspected lung cancer, detected by chest x-ray, revealed pneumonia. Bronchoscopy is frequently necessary for the diagnosis as well as the treatment as a routine practice and in this case was applied. Our patient underwent to fiberoptic rigid bronchoscopy in the right upper lobe in general anaesthesia. Unexpectedly, a vegetal FB, Medlar's core instead a tumor, was removed. After two-months follow-up the patient was found healthy without any old or other symptoms.

    The objective of this study was to describe high-resolution CT (HRCT) and MR findings of exogenous lipoid pneumonia and to correlate them with pathologic findings. A retrospective review of the medical records of our institution revealed seven patients with a diagnosis of lipoid pneumonia based on clinical data, chest films, bronchoalveolar lavage, and follow-up. Both HRCT and MR imaging were reviewed by two readers. Pathologic examination of the resected specimen or surgical biopsies were also reviewed in the four available cases. The HRCT findings were pulmonary consolidations (n = 6) with fatty (n = 3) or unspecific but low attenuation values (n = 3), areas of ground-glass opacities (n = 5), septal lines, and centrilobular interstitial thickening (n = 5). In five of the seven cases, a crazy-paving pattern of various spread was also present, either isolated (n = 1) or surrounding a pulmonary consolidation. In two cases traction bronchiectasis and cystic changes consistent with fibrosis were seen. At MR imaging (n = 2) a pulmonary consolidation of high signal intensity on T1-weighted image consistent with lipid content was present in one case. Pathologic examination (n = 4) showed the coexistence of lobules with lesions of various ages, sometimes in contiguous lobules, within the same patient. Recent lesions were those with alveolar fill-in by spumous macrophages and almost normal alveolar walls and septae. In more advanced lesions, lobules were filled in with larger vacuoles often surrounded by inflammatory infiltrates of alveolar walls, bronchiolar walls, and septa. The oldest lesions were characterized by fibrosis and parenchymal distortion around large lipid-containing vacuoles. The HRCT findings reflect pathologic findings in exogenous lipoid pneumonia. Although non-specific, consolidation areas of low attenuation values and crazy-paving pattern are frequently associated in exogenous lipoid pneumonia and are indicative of the diagnosis. (orig.)

    To determine the extent and pattern of treatment failure (TF) among children hospitalised with community-acquired pneumonia at a large tertiary hospital in Kenya. We followed up children aged 2-59 months with WHO-defined severe pneumonia (SP) and very severe pneumonia (VSP) for up to 5 days for TF using two definitions: (i) documentation of pre-defined clinical signs resulting in change of treatment (ii) primary clinician's decision to change treatment with or without documentation of the same pre-defined clinical signs. We enrolled 385 children. The risk of TF varied between 1.8% (95% CI 0.4-5.1) and 12.4% (95% CI 7.9-18.4) for SP and 21.4% (95% CI 15.9-27) and 39.3% (95% CI 32.5-46.4) for VSP depending on the definition applied. Higher rates were associated with early changes in therapy by clinician in the absence of an obvious clinical rationale. Non-adherence to treatment guidelines was observed for 70/169 (41.4%) and 67/201 (33.3%) of children with SP and VSP, respectively. Among children with SP, adherence to treatment guidelines was associated with the presence of wheeze on initial assessment (P = 0.02), while clinician non-adherence to guideline-recommended treatments for VSP tended to occur in children with altered consciousness (P < 0.001). Using propensity score matching to account for imbalance in the distribution of baseline clinical characteristics among children with VSP revealed no difference in TF between those treated with the guideline-recommended regimen vs. more costly broad-spectrum alternatives [risk difference 0.37 (95% CI -0.84 to 0.51)]. Before revising current pneumonia case management guidelines, standardised definitions of TF and appropriate studies of treatment effectiveness of alternative regimens are required. © 2014 The Authors.

    Out-of-pocket (OOP) medical payments can lead to catastrophic health expenditure and impoverishment. We quantified household OOP expenditure for treatment of childhood pneumonia and diarrhoea and its impact on poverty for different socioeconomic groups in Ethiopia. This study employs a mix of retrospective and prospective primary household data collection for direct medical and non-medical costs (2013 US$). Data from 345 pneumonia and 341 diarrhoea cases (0-59 months of age) were collected retrospectively through exit interviews from 35 purposively sampled health facilities in Ethiopia. Prospective 2-week follow-up interviews were conducted at the household level using a structured questionnaire. The mean total medical expenditures per outpatient visit were US$8 for pneumonia and US$6 for diarrhoea, while the mean for inpatient visits was US$64 for severe pneumonia and US$79 for severe diarrhoea. The mean associated direct non-medical costs (mainly transport costs) were US$2, US$2, US$13 and US$20 respectively. 7% and 6% of the households with a case of severe pneumonia and severe diarrhoea, respectively, were pushed below the extreme poverty threshold of purchasing power parity (PPP) US$1.25 per day. Wealthier and urban households had higher OOP payments, but poorer and rural households were more likely to be impoverished due to medical payments. Households in Ethiopia incur considerable costs for the treatment of childhood diarrhoea and pneumonia with catastrophic consequences and impoverishment. The present circumstances call for revisiting the existing health financing strategy for high-priority services that places a substantial burden of payment on households at the point of care.

  3. [Ceftaroline fosamil in community-acquired and nosocomial pneumonia].

    2014-03-01

    Community-acquired pneumonia (CAP) is a common infection in developed countries and causes a large number of hospital admissions and deaths. In recent years, the incidence of this disease has increased, caused by progressive population aging. Following the introduction of the conjugate vaccine against Streptococcus pneumoniae, there have been significant epidemiological changes that require close monitoring because of the possible emergence of new patterns of resistance. This article aims to review the role of ceftaroline fosamil, a new parenteral cephalosporin with antibacterial activity against Gram-negative and Gram-positive pathogens, in the treatment of pneumonia. Several in vitro and in vivo studies have shown the efficacy of ceftaroline fosamil against penicillin-resistant S. pneumoniae and methicillin-resistant Staphylococcus aureus (MRSA). Additionally, ceftaroline has shown similar efficacy and safety to ceftriaxone in the treatment of community-acquired pneumonia with severe prognosis (prognostic severity index III and IV) in two phase III clinical trials. Although a non-inferiority design was used for these clinical trials, some data suggest a superior efficacy of ceftaroline, with earlier clinical response and higher cure rate in infections caused by S. pneumoniae, making this drug particularly interesting for critically-ill patients admitted to the intensive care unit. Ceftaroline may also be considered for empirical and directed treatment of MRSA pneumonia. Copyright © 2014 Elsevier España, S.L. All rights reserved.

    Introduction Observational studies using case-control designs have showed an increased risk of pneumonia associated with inhaled corticosteroid (ICS)-containing medications in patients with chronic obstructive pulmonary disease (COPD). New-user observational cohort designs may minimize biases associated with previous case-control designs. Objective To estimate the association between ICS and pneumonia among new users of ICS relative to inhaled long-acting bronchodilator (LABD) monotherapy. Methods Pneumonia events in COPD patients ≥45 years old were compared among new users of ICS medications (n = 11,555; ICS, ICS/long-acting β2-agonist [LABA] combination) and inhaled LABD monotherapies (n = 6,492; LABA, long-acting muscarinic antagonists) using Cox proportional hazards models, with propensity scores to adjust for confounding. Setting: United Kingdom electronic medical records with linked hospitalization and mortality data (2002–2010). New users were censored at earliest of: pneumonia event, death, changing/discontinuing treatment, or end of follow-up. Outcomes: severe pneumonia (primary) and any pneumonia (secondary). Results Following adjustment, new use of ICS-containing medications was associated with an increased risk of pneumonia hospitalization (n = 322 events; HR = 1.55, 95% CI: 1.14, 2.10) and any pneumonia (n = 702 events; HR = 1.49, 95% CI: 1.22, 1.83). Crude incidence rates of any pneumonia were 48.7 and 30.9 per 1000 person years among the ICS-containing and LABD cohorts, respectively. Excess risk of pneumonia with ICS was reduced when requiring ≥1 month or ≥ 6 months of new use. There was an apparent dose-related effect, with greater risk at higher daily doses of ICS. There was evidence of channeling bias, with more severe patients prescribed ICS, for which the analysis may not have completely adjusted. Conclusions The results of this new-user cohort study are consistent with published findings; ICS were associated

    Full Text Available OBJECTIVE: To describe HRCT findings in patients with bacterial pneumonia following bone marrow transplantation (BMT. METHODS: This was a retrospective study involving 30 patients diagnosed with bacterial pneumonia in whom HRCT of the chest was performed within 24 h after the onset of symptoms and the diagnosis was confirmed, based on a positive culture of sputum or bronchial aspirate, together with a positive pleural fluid or blood culture, within one week after symptom onset. There were 20 male patients and 10 female patients. The median age was 21 years (range, 1-41 years. The BMT had been performed for the treatment of the following: chronic myeloid leukemia, in 14 cases; severe aplastic anemia, in 6; acute myeloid leukemia, in 4; Fanconi's anemia, in 3; and acute lymphocytic leukemia, in 3. Two radiologists analyzed the HRCT scans and reached their final decisions by consensus. RESULTS: The most common HRCT findings were air-space consolidation (in 60%, small centrilobular nodules (in 50%, ground-glass opacities (in 40%, bronchial wall thickening (in 20%, large nodules (in 20%, pleural lesions (in 16.7% and tree-in-bud opacities (in 10%. The pulmonary lesions were distributed in the central and peripheral areas in 15 patients, whereas they were exclusively peripheral in 11. Lesions were located in the lower and middle lobes of the lung in 22 and 20 patients, respectively. CONCLUSIONS: The most common HRCT findings in our patient sample were air-space consolidation, small centrilobular nodules and ground-glass opacities, most often in the central and peripheral regions of the middle and lower lung zones.OBJETIVO: Descrever os achados de TCAR em pacientes com pneumonia bacteriana após transplante de medula óssea (TMO.

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

    Roentgenographic findings of bilateral interstitial pneumonia without segmental consolidation and with regional lymphadenitis, which occurs after infancy, are always suggestive of pneumonia from Mycoplasma pneumoniae, as this is one of the most frequent types of pneumonia in children. M. pneumonia can be presumed by the discrepancy between the extensive roentgenographic findings and the generally good condition of the patient. Before therapy is decided upon it is important to know what the etiology is.

    Purpose: To assess the change in diagnostic confidence between first and follow-up dynamic MR examination of the breast (MRM). Methods: The reports of a total of 175 MRM in 77 patients (mean age 50 years; 36-76) with 98 follow-up MRM were analyzed. All examinations were performed as a dynamic study (Gd-DTPA, 0.16 mmol/kg; 6-7 repetitive studies). The change in diagnostic confidence was retrospectively classified as follows: Controlled lesion vanished during follow-up (category I); diagnostic confidence increases during follow-up (II), more likely benign (IIa), more suspicious (IIb); no difference in diagnostic confidence (III). Long-term follow-up over an average of four years was obtained for 57 patients with category IIa/III findings. Results: In 98 follow-up examinations, only two lesions vanished (2%). In 77/98 cases a category IIa lesion was diagnosed, in 11 cases a category IIb lesion. In 8 cases (8%) there was no change in diagnostic confidence during follow-up. Lesions in category IIb underwent biopsy in 10/11 cases, in one case long-term follow-up proved a completely regredient inflammatory change. In 8/11 suspicious findings (IIb) a malignant tumor was detected. The mean time interval between first and follow-up MRM was 8 months for I-IIb lesions, and 4 months for category III lesions. In the longterm follow-up two patients with a category II a lesion developed a carcinoma in a different breast area after four and five years. Conclusion: MRM follow up increases the diagnostic confidence if the time interval is adequate (>4 months). A persistently or increasingly suspicious finding warrants biopsy. (orig.) [de

    Full Text Available Mycoplasma pneumonia is a major cause of respiratory infections in school-aged children. Most M. pneumonia infections in adults involve the respiratory tract. Extrapulmonary manifestations of M. pneumonia infection may be found in the skin, cardiovascular, neurologic and hematologic systems. Concomitant liver disease is rare in adults. Here, we report an unusual case of a patient who presented with fever and abdominal pain, but without pulmonary manifestations. The laboratory work-up demonstrated a hepatocellular pattern of acute hepatitis caused by M. pneumonia infection. Symptoms subsided and laboratory parameters improved with antibiotics treatment. Thus, this case can help raise clinicians' awareness of the possibility of M. pneumonia infection, with or without lung involvement, as a part of the evaluation of undetermined hepatitis.

    Although improved during the past few years, blood pressure control remains sub optimal. The impact of follow-up assessment on blood pressure control was evaluated in a group of patients of the HYT (HYperTension survey), treated with a combination of different dihydropyridine calcium-channel blockers (CCBs regimen) and inhibitors of renin-angiotensin-aldosterone system (RAAS) and with uncontrolled blood pressure. This was obtained assessing (a) the rate of blood pressure control at 3 and 6 months of follow-up in the whole group of patients, (b) the rate of blood pressure control and the average blood pressure values in subjects treated with different DHP-CCBs regimen. From the 4993 patients with uncontrolled blood pressure, (BP ≥ 140/90 or ≥140/85 in patients with diabetes), 3729 (mean age 61.2 ± 11.5 years), maintained CCBs regimen combined wih RAAS blockers and were evaluated at 3 and 6 months follow-up. At each visit BP (semiautomatic device, Omron-M6, 3 measurements), heart rate, adverse events and treatment persistence were collected. At 1st and 2nd follow-up the rate of controlled BP was 63.5 and 72.8% respectively (p blood pressure control; (b) there is no significant difference in the antihypertensive effect between different CCBs regimen; (c) lipophilic CCBs induce less ankle edema.

    Full Text Available Aspiration pneumonia is a dominant form of community-acquired and healthcare-associated pneumonia, and a leading cause of death among ageing populations. However, the risk factors for developing aspiration pneumonia in older adults have not been fully evaluated. The purpose of the present study was to determine the risk factors for aspiration pneumonia among the elderly.We conducted an observational study using data from a nationwide survey of geriatric medical and nursing center in Japan. The study subjects included 9930 patients (median age: 86 years, women: 76% who were divided into two groups: those who had experienced an episode of aspiration pneumonia in the previous 3 months and those who had not. Data on demographics, clinical status, activities of daily living (ADL, and major illnesses were compared between subjects with and without aspiration pneumonia. Two hundred and fifty-nine subjects (2.6% of the total sample were in the aspiration pneumonia group. In the univariate analysis, older age was not found to be a risk factor for aspiration pneumonia, but the following were: sputum suctioning (odds ratio [OR] = 17.25, 95% confidence interval [CI]: 13.16-22.62, p < 0.001, daily oxygen therapy (OR = 8.29, 95% CI: 4.39-15.65, feeding support dependency (OR = 8.10, 95% CI: 6.27-10.48, p < 0.001, and urinary catheterization (OR = 4.08, 95% CI: 2.81-5.91, p < 0.001. In the multiple logistic regression analysis, the risk factors associated with aspiration pneumonia after propensity-adjustment (258 subjects each were sputum suctioning (OR = 3.276, 95% CI: 1.910-5.619, deterioration of swallowing function in the past 3 months (OR = 3.584, 95% CI: 1.948-6.952, dehydration (OR = 8.019, 95% CI: 2.720-23.643, and dementia (OR = 1.618, 95% CI: 1.031-2.539.The risk factors for aspiration pneumonia were sputum suctioning, deterioration of swallowing function, dehydration, and dementia. These results could help improve clinical management for preventing

    Nasal polyposis is often found in patients with cystic fibrosis. To assess the incidence of nasal polyposis, the response to medical treatment, recurrence and the need for surgical intervention in children and adolescents with cystic fibrosis during a three-year follow-up. Clinical symptoms (pulmonary, pancreatic insufficiency, malnutrition, nasal obstruction), two positive sweat chloride tests, and genotype findings in 23 patients with cystic fibrosis were analyzed. All patients underwent nasal endoscopy every 12 months from January 2005 to December 2007, to assess the presence and grade of Nasal Polyps. Nasal polyposis, when present, were treated with topical corticosteroids for 6-12 months, with progress being evaluated within the 3 years of follow-up. In the first evaluation, nasal polyposis was diagnosed in 30.43% of patients (3 bilateral and 4 unilateral), recurrent pneumonia in 82.6%, pancreatic insufficiency in 87%, and malnutrition in 74%. The presence of nasal polyposis was not associated with chloride values in the sweat, genotype, clinical signs of severity of cystic fibrosis, or nasal symptoms. In the three-year period of follow up, 13 patients (56.52%) had at least one event of polyposis, with the youngest being diagnosed at 32 months of age. Only one patient underwent surgery (polypectomy), and there was one diagnosis of nasopharyngeal carcinoma. The study showed a high incidence of nasal polyposis. Monitoring through routine endoscopy in patients with cystic fibrosis, even in the absence of nasal symptoms, is highly recommended. The therapy with topical corticosteroids achieved good results. Thus, an interaction between pediatricians and otolaryngologists is necessary. Copyright © 2016 Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial.

O M. pneumoniae não foi isolado. O diagnóstico presuntivo de infecção pelo M. pneumoniae foi feito pela FC em 3,1% (2/64 e pela CIE em 1,6% (1/64 dos pacientes. Paralelamente, em 200 indivíduos sadios, os mesmos testes sorológicos foram realizados, sendo o índice de positividade de 4% (8/200 pela CIE e de 1% (2/200 pela FC. Apesar das aiscrepâncias observadas entre os dois métodos sorológicos, a FC parece ser indicada para diagnóstico da infecção, sendo a CIE recomendada nas avaliações soroepidemiológicas. Com base nos dados do nosso estudo, a prevalência das infecções respiratórias pelo M. pneumoniae parece ser baixa em nosso meio.

    Full Text Available BACKGROUND: Viruses are increasingly recognized as major causes of community-acquired pneumonia (CAP. Few studies have investigated the clinical predictors of viral pneumonia, and the results have been inconsistent. In this study, the clinical predictors of viral pneumonia were investigated in terms of their utility as indicators for viral pneumonia in patients with CAP. METHODS: Adult patients (≥ 18 years old with CAP, tested by polymerase chain reaction (PCR for respiratory virus, at two teaching hospitals between October 2010 and May 2013, were identified retrospectively. Demographic and clinical data were collected by reviewing the hospital electronic medical records. RESULTS: During the study period, 456 patients with CAP were identified who met the definition, and 327 (72% patients were tested using the respiratory virus PCR detection test. Viral pneumonia (n = 60 was associated with rhinorrhea, a higher lymphocyte fraction in the white blood cells, lower serum creatinine and ground-glass opacity (GGO in radiology results, compared to non-viral pneumonia (n = 250 (p < 0.05, each. In a multivariate analysis, rhinorrhea (Odd ratio (OR 3.52; 95% Confidence interval (CI, 1.58-7.87 and GGO (OR 4.68; 95% CI, 2.48-8.89 were revealed as independent risk factors for viral pneumonia in patients with CAP. The sensitivity, specificity, positive- and negative-predictive values (PPV and NPV of rhinorrhea were 22, 91, 36 and 83%: the sensitivity, specificity, PPV and NPV of GGO were and 43, 84, 40 and 86%, respectively. CONCLUSION: Symptom of rhinorrhea and GGO predicted viral pneumonia in patients with CAP. The high specificity of rhinorrhea and GGO suggested that these could be useful indicators for empirical antiviral therapy.

    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.

    Full Text Available The prevalence of gastroesophagel reflux disease (GERD has steadily increased. However, the association between GERD itself and the risk of pneumonia remains unclear. This study aimed to investigate the association between GERD and long-term risk of pneumonia and to identify the major risk factors for pneumonia in GERD patients.Using the Taiwan National Health Insurance Research Database, we identified patients who were newly diagnosed with GERD and treated with proton pump inhibitors (PPIs from January 1, 2004 through December 31, 2010. Two groups comprising 15,715 GERD cases and 15,715 non-GERD matched controls were generated using propensity score matching, thereby making the differences in basic demographics, concomitant medication use, and comorbidities between the two groups inconsiderable.Cumulative incidence of pneumonia was significantly higher in the patients with GERD than that in the non-GERD matched controls, with an adjusted HR of 1.48 (95% confidence interval [CI] = 1.31-1.67; P < 0.001 within 6-year follow-ups. Multivariate stratified analyses revealed similar results in many subgroups, with a highest risk in individuals younger than 40 years of age (HR = 2.17, 95% CI = 1.48-3.19. Crucially, patients with GERD using PPIs longer than 4 months were at a significantly increased risk of pneumonia than those who did not use PPIs or took PPIs less than 4 months.GERD was significantly associated with long-term risk of pneumonia, especially in GERD with PPI use longer than 4 months or in the young population. Further prospective longitudinal studies should be conducted for validation and implementing clinical practice guidelines.

    We present a 74-year-old male with nonspecific interstitial pneumonia (NSIP) during treatment with ibrutinib for mantle cell lymphoma. Previously, the patient had received six cycles of bendamustine and rituximab and six cycles of R-CHOP, followed by rituximab maintenance therapy. Respiratory tract complications of ibrutinib other than infectious pneumonia have not been mentioned in larger trials, but individual case reports hinted to a possible association with the development of pneumonitis. In our patient, the onset of alveolitis that progressed towards NSIP together with the onset of ibrutinib treatment suggests causality. One week after ibrutinib was discontinued, nasal symptoms resolved first. A follow-up CT showed a reduction in the reticular hyperdensities and ground-glass opacities, suggestive of restitution of the lung disease. To our knowledge, this is the first case showing a strong link between ibrutinib and interstitial lung disease, strengthening a previous report on subacute pneumonitis. Our findings have clinical implications because pulmonary side effects were reversible at this early stage. We, therefore, suggest close monitoring for respiratory side effects in patients receiving ibrutinib.

    Despite a considerable number of antimicrobial agents and interdisciplinary treatment options, lower respiratory tract infections are still associated with high morbidity and mortality rates. Infections of the respiratory tract can lead to severe complications, such as empyema, lung abscesses and acute respiratory distress syndrome (ARDS). Besides intrapulmonary complications pneumonia can also impair other organs due to a systemic inflammatory response. Underlying cardiovascular diseases, such as chronic heart failure, arteriosclerosis and dysrhythmia can either deteriorate due to infections or be newly manifested as a result of pneumonia. Early diagnosis and therapy of these sometimes life-threatening complications are crucial and can have a severe impact on disease outcome. The most important imaging techniques include chest X-ray and computed tomography (CT) of the chest. Although a definite diagnosis is sometimes difficult or even impossible to establish using chest X-ray or CT, there are several findings indicative of intrapulmonary or extrapulmonary complications of pneumonia. Another useful and portable tool is thoracic ultrasound directly on the patient, which can be used to further define the underlying disease or as guidance during procedures. The chest X-ray is useful in initial diagnosis and follow-up. If complications or disease progression are suspected or the clinical course differs from the X-ray interpretation, a subsequent CT of the chest should be performed. (orig.) [de

    Full Text Available Abstract Background Hospital associated infections are major problems, which are increasing in incidence and very costly. However, most research has focused only on measuring consequences associated with the initial hospitalization. We explored the long-term consequences of infections in elderly Medicare patients admitted to an intensive care unit (ICU and discharged alive, focusing on: sepsis, pneumonia, central-line-associated bloodstream infections (CLABSI, and ventilator-associated pneumonia (VAP; the relationships between the infections and long-term survival and resource utilization; and how resource utilization was related to impending death during the follow up period. Methods Clinical data and one year pre- and five years post-index hospitalization Medicare records were examined. Hazard ratios (HR and healthcare utilization incidence ratios (IR were estimated from state of the art econometric models. Patient demographics (i.e., age, gender, race and health status and Medicaid status (i.e., dual eligibility were controlled for in these models. Results In 17,537 patients, there were 1,062 sepsis, 1,802 pneumonia, 42 CLABSI and 52 VAP cases. These subjects accounted for 62,554 person-years post discharge. The sepsis and CLABSI cohorts were similar as were the pneumonia and VAP cohorts. Infection was associated with increased mortality (sepsis HR = 1.39, P  Conclusions The infections had significant and lasting adverse consequences among the elderly. Yet, many of these infections may be preventable. Investments in infection prevention interventions are needed in both community and hospitals settings.

    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.

    Full Text Available Pneumonia in pregnancy is associated with adverse maternal and foetal outcomes, and intensive treatment with appropriate antibiotics is essential. However, cases caused by pathogens that are resistant to antibiotics suitable for the developing foetus are challenging. We herein report a case of macrolide-refractory Mycoplasma pneumoniae pneumonia in pregnancy. A 40-year-old multigravida with twin pregnancy complained of cough and fever at 13 weeks of gestation and was diagnosed with pneumonia. Even though empiric treatment with ceftriaxone and oral azithromycin was started, her condition deteriorated rapidly. The findings of chest computed tomography suggested Mycoplasma pneumoniae pneumonia. Since azithromycin did not work, this strain was considered to be macrolide-refractory. Garenoxacin, an oral quinolone, was selected and was dramatically effective. The use of quinolone could be justified with the emergence of drug-resistant bacterial/atypical pneumonia and in the maternal life-threatening condition.

    The first patient showed ill-defined ground-glass opacity nodules and patchy areas of ground-glass attenuation. The second, with secondary bacterial pneumonia, showed bilateral areas of lobar consolidation and ground-glass opacities. The predominant HRCT findings reported bilateral, peripheral, ground-glass opacities and/or bilateral areas of consolidation. The patients who presented with consolidations had a more severe clinical course. Limited data are available, however, on the tomographic or pathological aspects observed during the recovery phase after H1N1 infection. During the treatment and recovery phases, persistent opacities on radiographs may not be informative enough to distinguish disease progression from healing. HRCT may play a role in the detection and characterization of the disease, in monitoring the disease progress and response to treatment, as well as in the identification of complications. In conclusion, although pulmonary opacities secondary to H1N1 infection usually regress during convalescence, the consolidations may occasionally progress to linear opacities (parenchymal bands). These linear opacities probably represent organizing pneumonia.

    Community-acquired pneumonia (CAP) is a common infectious disease affecting children and adults of any age. Mycoplasma pneumoniae has emerged as leading causative agent of CAP in some region, and the abrupt increasing resistance to macrolide that widely used for management of M. pneumoniae has reached to the level that it often leads to treatment failures. We aim to discuss the drivers for development of macrolide-resistant M. pneumoniae, antimicrobial stewardship and also the potential treatment options for patients infected with macrolide-resistant M. pneumonia. The articles in English and Chinese published in Pubmed and in Asian medical journals were selected for the review. M. pneumoniae can develop macrolide resistance by point mutations in the 23S rRNA gene. Inappropriate and overuse of macrolides for respiratory tract infections may induce the resistance rapidly. A number of countries have introduced the stewardship program for restricting the use of macrolide. Tetracyclines and fluoroquinolones are highly effective for macrolide-resistant strains, which may be the substitute in the region of high prevalence of macrolide-resistant M. pneumoniae. The problem of macrolide resistant M. pneumonia is emerging. Antibiotic stewardship is needed to inhibit the inappropriate use of macrolide and new antibiotics with a more acceptable safety profile for all ages need to be explored. © 2015 John Wiley & Sons Ltd.

    This study aimed to compare the outcomes for Heller myotomy alone and combined with different partial fundoplications. The authors retrospectively reviewed their experience with 69 laparoscopic myotomies and 14 Heller myotomies, 80% of which were performed with partial fundoplication including 20 Toupet, 18 Dor, and 17 modified Dor procedures, in which the fundoplication is sutured to both sides of the crura and not the myotomy. The mean age of the study patients was 69 years (range, 15-80 years). Four mucosal perforations were repaired intraoperatively. There was one small bowel fistula in an area of open hernia repair distant from the myotomy. One patient with severe chronic obstructive pulmonary disease died of pneumonia. Phone follow-up evaluation was achieved in 68% of the cases at a mean of 37 months (range, 2-97 months). The results for no dysphagia and for heartburn requiring proton pump inhibitors, respectively, were as follows: Heller myotomy (85.7%, 28.5%), Toupet (66.6%, 33.3%), Dor (83.3%, 20%), and modified Dor (84.6%, 15.3%). Two patients with reflux strictures required annual dilation (Toupet, Dor). Two patients required revisions: one redo Heller myotomy (Dor) and one esophageal replacement (Toupet). Heller myotomy provides excellent dysphagia relief with or without fundoplication. Heartburn is a significant problem for a minority of patients. In the authors' hands, Toupet had the worst results and modified Dor was most protective for heartburn.

    Klebsiella pneumoniae has a reputation for causing a wide range of infectious conditions, with numerous highly virulent and antibiotic-resistant strains. Metabolic models have the potential to provide insights into the growth behavior, nutrient requirements, essential genes, and candidate drug targets in these strains. Here we develop a metabolic model for KPPR1, a highly virulent strain of K. pneumoniae. We apply a combination of Biolog phenotype data and fitness data to validate and refine our KPPR1 model. The final model displays a predictive accuracy of 75% in identifying potential carbon and nitrogen sources for K. pneumoniae and of 99% in predicting nonessential genes in rich media. We demonstrate how this model is useful in studying the differences in the metabolic capabilities of the low-virulence MGH 78578 strain and the highly virulent KPPR1 strain. For example, we demonstrate that these strains differ in carbohydrate metabolism, including the ability to metabolize dulcitol as a primary carbon source. Our model makes numerous other predictions for follow-up verification and analysis.

    To evaluate the volume change of peritoneal inclusion cysts on the follow-up ultrasonography (US). From March 1995 to May 1999, thirty seven women with ultrasonographically diagnosed peritoneal inclusion cysts were included in this study. Six patients underwent surgery for several reasons. Follow-up ultrasonography was performed 70-456 days (mean=191 days) after initial US examination in 12 of the remaining 31 patient with no further treatment. US was performed with a 3.5 or 4 MHz transabdominal probe in all 18 patients who underwent either surgery or follow-up US, and additional tranvaginal US examination using a 5-7 MHz probe in 15 of 18 patients. The volume change of the cysts was recorded for each US examination. Three cysts (25%) (volume=170 cm 3 , 61 cm 3 , and 38 cm 3 , respectively) were completely resolved on the follow-up US while the other nine cysts showed a decreased volume in seven patients (58%) and increased volume in two patients (17%). Spontaneous regression of peritoneal inclusion cysts is more common than it is believed to be, and ultrasonography may be a useful follow-up examination for peritoneal inclusion cysts.

    Cough reflex testing has been evaluated as a component of the clinical swallowing assessment as a means of identifying patients at risk of aspiration during swallowing. A previous study by our research group found good sensitivity and specificity of the cough reflex test for identifying patients at risk of aspiration post-stroke, yet its use did not decrease pneumonia rates, contrary to previous reports. The aim of this study was to expand on our earlier work by implementing a clinical management protocol incorporating cough reflex testing within the same healthcare setting and compare patient outcomes to those from the original study and to evaluate clinical outcomes in patients with acute stroke who were managed using the Dysphagia in Stroke Protocol (DiSP). Secondarily, to compare those outcomes to historical data prior to implementation of the DiSP. This clinical audit measured outcomes from 284 patients with acute stroke managed per the DiSP, which guides use of videofluoroscopic swallowing study and patient management based on clinical exam with cough reflex testing. Data from our previous trial were included for comparison of pre- and post-DiSP patient outcomes. Data collection took place between November 2012 and April 2016 at four urban hospitals within New Zealand. Following implementation of the DiSP, the rate of aspiration pneumonia (10%) was substantially lower than the pre-DiSP rate (28%), with no pneumonia readmissions within 3 months. Pneumonia-related mortality was unchanged. By 3 months, 81% of the patients were on a normal diet and 67% had returned home, compared to pre-DiSP outcomes of 55% and 55% respectively. Previous work has suggested that simply implementing cough reflex testing in dysphagia management may not be sufficient to improve patient outcomes. The present study adds to this picture by suggesting that the true variable of influence may be the way in which the results of the test are applied to patient care. There is a strong case

    Full Text Available Epilepsy is the main neurological condition in children and adolescents. Unfortunately patients with medical refractory epilepsy are more susceptible for clinical complications and death. We report a prospectively evaluated cohort of children followed for approximately 10 years. Fifty-three of 1012 patients died. Forty-two patients died due to epilepsy or its clinical complications and the main causes of death were pneumonia (in 16 cases, sepses (in 9 patients, status epilepticus (in 8 patients. In 11 patients cause of death was sudden unexpected death in epilepsy (SUDEP. Mental retardation was significantly more frequent in patients who did not die from SUDEP. SUDEP may be a significant condition associated with mortality in children and adolescents with epilepsy.

    The introduction of high-resolution manometry (HRM) offered an improved method to objectively analyze the status of pharynx and esophagus. At present, HRM for patients with oropharyngeal dysphagia has been poorly studied. We aimed to determine feeding method and predict the development of aspiration pneumonia in patients with oropharyngeal dysphagia using HRM. We recruited 120 patients with dysphagia who underwent both HRM and videofluoroscopic swallow study. HRM was used to estimate pressure events from velopharynx (VP) to upper esophageal sphincter (UES). Feeding methods were determined to non-oral or oral feeding according to dysphagia severity. We prospectively followed patients to assess the development of aspiration pneumonia. VP maximal pressure and UES relaxation duration were independently associated with non-oral feeding. Non-oral feeding was determined based on optimal cutoff value of 105.0 mm Hg for VP maximal pressure (95.0% sensitivity and 70.0% specificity) and 0.45 s for UES relaxation duration (76.3% sensitivity and 57.5% specificity), respectively. During a mean follow-up of 18.8 months, 15.8% of patients developed aspiration pneumonia. On multivariate Cox regression analysis, VP maximal pressure (Pdysphagia.

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

    Two patients, treated with acebutolol and amiodarone respectively, developed a disease clinically, radiologically, and pathologically indistinguishable from bronchiolitis obliterans organising pneumonia. In one case recovery followed discontinuation of acebutolol; in the other case cessation of amiodarone had no effect, and corticosteroids were required. In addition to these patients, several cases of bronchiolitis obliterans organising pneumonia have been reported during treatment with gold salts, amiodarone, and miscellaneous other drugs. Taken together, this information supports the view that bronchiolitis obliterans organising pneumonia may be a form of response by the lungs to insult by drugs. Images PMID:2588206

    Full Text Available Hydatid disease is caused by Echinococcus granulosus. In this study, we aimed to investigate the benefit of monitoring cases with hydatid cyst by means of immune components in patients in a long-term follow-up after surgery. Eighty-four preoperative and postoperative serum samples from 14 cases undergoing surgery for hydatid disease were evaluated in terms of immune parameters, such as total and specific IgE, IgG, IgM, IgA and complement. Total and specific IgE were determined by ELISA. Specific IgG levels were measured by indirect hemaglutination.Total IgG, IgM, IgA and complement (C3 and C4 were detected by nephelometry. Imaging studies were also carried out during the follow-up. In none of the patients hydatid cysts were detected during the follow-up. Total IgE levels in the sera of the patients decreased to normal six months after surgery. Although specific IgE against echinococcal antigens decreased one year after operation, levels were still significantly high. There were no changes in the levels of anti-Echinococcus IgG and total IgG in follow-up period. Additionally, other parameters, such as IgA, IgM, C3 and C4, were not affected.

    Lifestyle interventions among people with impaired glucose tolerance reduce the incidence of diabetes, but their effect on all-cause and cardiovascular disease mortality is unclear. We assessed the long-term effect of lifestyle intervention on long-term outcomes among adults with impaired glucose tolerance who participated in the Da Qing Diabetes Prevention Study. The study was a cluster randomised trial in which 33 clinics in Da Qing, China-serving 577 adults with impaired glucose tolerance-were randomised (1:1:1:1) to a control group or lifestyle intervention groups (diet or exercise or both). Patients were enrolled in 1986 and the intervention phase lasted for 6 years. In 2009, we followed up participants to assess the primary outcomes of cardiovascular mortality, all-cause mortality, and incidence of diabetes in the intention-to-treat population. Of the 577 patients, 439 were assigned to the intervention group and 138 were assigned to the control group (one refused baseline examination). 542 (94%) of 576 participants had complete data for mortality and 568 (99%) contributed data to the analysis. 174 participants died during the 23 years of follow-up (121 in the intervention group vs 53 in the control group). Cumulative incidence of cardiovascular disease mortality was 11.9% (95% CI 8.8-15.0) in the intervention group versus 19.6% (12.9-26.3) in the control group (hazard ratio [HR] 0.59, 95% CI 0.36-0.96; p=0.033). All-cause mortality was 28.1% (95% CI 23.9-32.4) versus 38.4% (30.3-46.5; HR 0.71, 95% CI 0.51-0.99; p=0.049). Incidence of diabetes was 72.6% (68.4-76.8) versus 89.9% (84.9-94.9; HR 0.55, 95% CI 0.40-0.76; p=0.001). A 6-year lifestyle intervention programme for Chinese people with impaired glucose tolerance can reduce incidence of cardiovascular and all-cause mortality and diabetes. These findings emphasise the long-term clinical benefits of lifestyle intervention for patients with impaired glucose tolerance and provide further justification for

    In 1995 Clalit Health Services introduced a structured follow-up schedule, by primary care nurses, of diabetic patients. This was supplementary care, given in addition to the family physician's follow-up care. This article aims to describe the performance of diabetes follow-up and diabetes control in patients with additional structured nursing follow-up care, compared to those patients followed only by their family physician. We randomly selected 2,024 type 2 diabetic subjects aged 40-76 years. For each calendar year, from 2005-2007, patients who were "under physician follow-up only" were compared to those who received additional structured nursing follow-up care. Complete diabetes follow-up parameters including: HbA1c, LDL cholesterol, microalbumin, blood pressure measurements and fundus examination. The average age of study participants was 60.7 years, 52% were females and 38% were from low socioeconomic status (SES). In 2005, 39.5% of the diabetic patients received structured nursing follow-up, and the comparable figures for 2006 and 2007 were 42.1% 49.6%, respectively. The intervention subjects tended to be older, from lower SES, suffered from more chronic diseases and visited their family physician more frequently than the control patients. Patients in the study group were more likely to perform a complete diabetes follow-up plan: 52.8% vs. 21.5% (2005; p nursing follow-up care were more likely to perform complete diabetes follow-up protocol. Our results reinforce the importance of teamwork in diabetic care. Further study is required to identify strategies for channeling the use of the limited resources to the patients who stand to benefit the most.

    To assess the high-resolution CT (HRCT) findings of small airway abnormalities after mycoplasma pneumonia and correlate them with the findings of chest radiography performed during the acute and follow-up phases of the condition. We retrospectively evaluated HRCT and chest radiographic findings of 18 patients with clinical diagnosis of small airway disease after mycoplasma pneumonia (M:F=8:10, mean age: 8.3 years, mean time interval after the initial infection; 26 menths). We evaluated the lung parenchymal and bronchial abnormalities on HRCT (n=18). In addition, presence of air-trapping was assessed on expiratory scans (n=13). The findings of HRCT were correlated with those of chest radiography performed during the acute phase of initial infection (n=15) and at the time of CT examination (n=18), respectively.

    To assess the high-resolution CT (HRCT) findings of small airway abnormalities after mycoplasma pneumonia and correlate them with the findings of chest radiography performed during the acute and follow-up phases of the condition. We retrospectively evaluated HRCT and chest radiographic findings of 18 patients with clinical diagnosis of small airway disease after mycoplasma pneumonia (M:F=8:10, mean age: 8.3 years, mean time interval after the initial infection; 26 menths). We evaluated the lung parenchymal and bronchial abnormalities on HRCT (n=18). In addition, presence of air-trapping was assessed on expiratory scans (n=13). The findings of HRCT were correlated with those of chest radiography performed during the acute phase of initial infection (n=15) and at the time of CT examination (n=18), respectively. HRCT revealed lung parenchymal abnormalities in 13 patients (72%). A mosaic pattern of lung attenuation was noted in ten patients (10/18, 56%) and air-trapping on expiratory scans was observed in nine (9/13), 69%).

    Full Text Available Abstract Background The follow-up rate, a standard index of the completeness of follow-up, is important for assessing the validity of a cohort study. A common method for estimating the follow-up rate, the “Percentage Method”, defined as the fraction of all enrollees who developed the event of interest or had complete follow-up, can severely underestimate the degree of follow-up. Alternatively, the median follow-up time does not indicate the completeness of follow-up, and the reverse Kaplan-Meier based method and Clark’s Completeness Index (CCI also have limitations. Methods We propose a new definition for the follow-up rate, the Person-Time Follow-up Rate (PTFR, which is the observed person-time divided by total person-time assuming no dropouts. The PTFR cannot be calculated directly since the event times for dropouts are not observed. Therefore, two estimation methods are proposed: a formal person-time method (FPT in which the expected total follow-up time is calculated using the event rate estimated from the observed data, and a simplified person-time method (SPT that avoids estimation of the event rate by assigning full follow-up time to all events. Simulations were conducted to measure the accuracy of each method, and each method was applied to a prostate cancer recurrence study dataset. Results Simulation results showed that the FPT has the highest accuracy overall. In most situations, the computationally simpler SPT and CCI methods are only slightly biased. When applied to a retrospective cohort study of cancer recurrence, the FPT, CCI and SPT showed substantially greater 5-year follow-up than the Percentage Method (92%, 92% and 93% vs 68%. Conclusions The Person-time methods correct a systematic error in the standard Percentage Method for calculating follow-up rates. The easy to use SPT and CCI methods can be used in tandem to obtain an accurate and tight interval for PTFR. However, the FPT is recommended when event rates and

    Little is known about the benefits of social networks in the management of patients. The aim of this study was to compare the effects of self-management (SM) education using telephone follow-up and mobile phone-based social networking on SM behaviors among patients with hypertension. This randomized clinical trial was conducted with 100 patients. They were randomly allocated to four groups: (i) control, (ii) SM training without follow-up, (iii) telephone follow-up and (iv) smartphone-based social networking follow-up. The hypertension SM behavior questionnaire was used for data collection before and six weeks after the study. Those patients who underwent SM education training (with and without follow-up) had statistically significant differences from those in the control group in terms of SM behaviors (p social networking follow-up influenced SM behaviors among patients with hypertension.

    Objective: To describe the chest computed tomographic (CT) findings of Legionella pneumophila pneumonia. Methods: CT scans obtained from 23 sporadic cases of L. pneumophila pneumonia were retrospectively reviewed. Chest CT findings were analyzed with regard to the patterns and distributions of pulmonary abnormalities. We also analyzed the histopathology of lungs from guinea pigs with experimentally induced L. pneumophila pneumonia. Results: Consolidation and ground-glass opacity (GGO) were the main findings of CT scans in L. pneumophila pneumonia. The distribution of opacities was categorized as non-segmental (n = 20) and segmental (n = 4). Non-segmental distribution may follow an onset of segmental distribution. Pleural effusion was observed in 14 (58.3%) patients, of which 13 were accompanied with non-segmental distribution. Abscess formation was observed in only one immunocompromised patient. In the animal pneumonia model, the lesions comprised of terminal bronchioles, alveolar spaces, and interstitia. Small bacilli were observed to be contained by many macrophages within the alveoli. Conclusion: Non-segmental distribution was significantly more frequent than segmental distribution in L. pneumophila pneumonia. It is possible that L. pneumophila infection initially results in segmental pneumonia, which progresses to typical non-segmental distribution.

    Full Text Available There are an estimated 150 million episodes of childhood pneumonia per year, with 11-20 million hospital admissions and 1.575 million deaths. Refugee children are particularly vulnerable, with poorly defined pneumonia epidemiology.We followed a birth cohort of 955 refugee infants, born over a one-year period, until two years of age. Clinical and radiographic pneumonia were diagnosed according to WHO criteria. Detailed characteristics were collected to determine risk factors for clinical, radiological and multiple episodes of pneumonia. Investigations were taken during a pneumonia episode to help determine or to infer an aetiological diagnosis.The incidence of clinical pneumonia was 0.73 (95% CI 0.70-0.75 episodes per child year (/CY and of radiological primary endpoint pneumonia (PEP was 0.22/CY (95% CI 0.20-0.24. The incidence of pneumonia without severe signs was 0.50/CY (95% CI 0.48-0.53, severe pneumonia 0.15/CY (95% CI 0.13-0.17 and very severe pneumonia 0.06/CY (0.05-0.07. Virus was detected, from a nasopharyngeal aspirate, in 61.3% of episodes. A reduced volume of living space per person (IRR 0.99, 95% CI 0.99-1.0, p = 0.003 and young maternal age (IRR 1.59, 95% CI 1.12-2.27, p = 0.01 were risk factors for developing pneumonia. The risk of a child having >1 episode of pneumonia was increased by having a shorter distance to the next house (IRR 0.86, 95% CI 0.74-1.00, p = 0.04. Infants were at risk of having an episode of PEP if there was a shorter distance from stove to bed (IRR 0.89, 95% CI 0.80-0.99, p = 0.03. Raised CRP and neutrophil values were associated with PEP.There was a high incidence of pneumonia in young children in this SE Asian refugee population. Viral infections were important, however CXR and non-specific marker findings suggested that bacteria may be involved in up to a third of cases.

    Full Text Available ABSTRACT Objective: To analyze the temporal trends in pneumonia mortality rates (standardized by age, using the 2010 population of Brazil as the standard in all Brazilian geographical regions between 1996 and 2012. Methods: This was an ecological time-series study examining secondary data from the Mortality Database maintained by the Information Technology Department of the Brazilian Unified Health Care System. Polynomial and joinpoint regression models, and corresponding 95% CIs, were used for trend analysis. Results: The pneumonia mortality rates in the South, Southeast, and Central-West showed a decreasing behavior until 2000, followed by increases, whereas, in the North and Northeast, they showed increasing trends virtually throughout the period studied. There was variation in annual percent change in pneumonia mortality rates in all regions except the North. The Central-West had the greatest decrease in annual percent change between 1996 and 2000, followed by an increase of the same magnitude until 2005. The 80 years and over age group was the one most influencing the trend behavior of pneumonia mortality rates in all regions. Conclusions: In general, pneumonia mortality trends reversed, with an important increase occurring in the years after 2000.

    Streptococcus pneumonia is the most common bacterial cause of community-acquired pneumonia in children. The reference standard for etiological diagnosis is isolation of S. pneumoniae from blood Since the advent of conjugate vaccines, disease caused by this organism can now be prevented. Many studies have been performed of the global incidence of invasive pneumococcal infections and of pneumococcal meningitis but few studies investigated bacteremic pneumococcal pneumonia and its complications in children. To determine the incidence, patient characteristics, clinical signs, laboratory data, percentage and days of hospitalization, response to antibiotic treatment, antibiotic resistance, complications and causal serogroups of bacteremic pneumococcal pneumonia in our environment in order to estimate requirements for systematic vaccination programs. From January 1990 to May 2001, data on all pediatric cases of invasive pneumococcal infections diagnosed in our hospital were collected. Several characteristics of patients with bacteremic pneumococcal pneumonia were analyzed. Bacteremic pneumococcal pneumonia was diagnosed in patients with positive blood or pleural fluid cultures for S. pneumoniae and radiographically evident pulmonary infiltrate. The incidence of both types of pneumonia were determined according to population census data. All S. pneumonia strains were sent to the Pneumococci Reference Laboratory of the Instituto Carlos III in Madrid for serotyping. We estimated the serotype coverage of the pneumococcal 7-valent conjugate vaccine according to the serotypes included in this vaccine and their distribution. Forty cases of bacteremic pneumococcal pneumonia were diagnosed, yielding an incidence of 17,10 and 5 cases per 10(5) children aged less than 2, 4 and 15 years old respectively. The mean age was 50 months and 43% were aged less than 4 years. Peaks occurred in January, March, April and May. A total of 77.5% of the patients were admitted to hospital and the

    The authors report a case of lipoid pneumonia in an 80 year old man with chronic constipation in regular use of mineral oil as a laxative. According to his family, he experienced coughing episodes when he took his medication. He also presented dyspnoea at rest and diminished consciousness levels. Chest radiographs showed a consolidation area in the posterior segment of right upper lobe, which did not change on successive exams. High resolution computed tomography demonstrated low-density consolidation with negative Hounsfield units (-29 to -83 UH) and ground-glass opacities in the right upper lobe and inferior lobes. These opacities predominated in the posterior regions of the lungs. The diagnosis was confirmed by the presence of oil material on bronchoalveolar washing. The patient was advised to discontinue the ingestion of mineral oil and did not return for follow-up. (author)

    Because the few previous studies on underlying causes of recurrent pneumonia in children have come from tertiary care referral centres where selection bias may be important, the aim of this study was to examine underlying causes of recurrent pneumonia in children in a general hospital. We performed a retrospective chart review in a general hospital of 62 children with recurrent pneumonia over a 7.5 years period. In 19 patients (30.6%), no cause was identified, commonly because favourable natural history obviated the need for a full and invasive diagnostic work-up. Other underlying causes included recurrent aspiration in 16 patients (25.7%), lung disease (airway stenosis, bronchiectasis, middle lobe syndrome or tracheooesophageal fistula) in 10 patients (16.1%) and immune deficiency in 10 patients (16.1%). In contrast to previous studies, asthma was never diagnosed as an underlying cause, but diagnostic confusion between asthma (or recurrent upper respiratory tract infections) and recurrent pneumonia was common. The cause of recurrent pneumonia in children remains elusive in almost a third of patients, partly because the favourable natural history consistent with immune system maturation eliminates the need for further diagnostic procedures. Asthma is more likely a differential diagnostic consideration than an underlying cause of recurrent pneumonia in children. A standardised diagnostic guideline is needed to improve knowledge on causes of recurrent pneumonia in children. © 2013 The Authors.

    BACKGROUND Pneumonia is one of the most common causes of death from infectious disease in the United States (US). Although most cases of community-acquired pneumonia (CAP) are secondary to bacterial infection, up to one-third of cases are secondary to viral infection, most commonly due to rhinovirus and influenza virus. Pneumonia due to herpes simplex virus (HSV) is rare, and there is limited knowledge of the pathogenesis and clinical complications. This report is of a fatal case of HSV pneumonia associated with bilateral pneumothorax and pneumomediastinum. CASE REPORT A 36-year-old homeless male Hispanic patient, who was a chronic smoker, with a history of intravenous drug abuse and a medical history of chronic hepatitis C virus (HCV) and human immunodeficiency virus (HIV) infection, not on highly active antiretroviral therapy (HAART), was admitted to hospital as an emergency with a seven-day history of productive purulent cough. The patient was admitted to the medical intensive care unit (MICU) with a diagnosis of CAP, with intubation and mechanical ventilation. Broncho-alveolar lavage (BAL) was performed and was positive for HSV. The patient developed bilateral pneumothorax with pneumomediastinum, which was fatal, despite aggressive clinical management. CONCLUSIONS Pneumonia due to HSV infection is uncommon but has a high mortality. Although HSV pneumonia has been described in immunocompromised patients, further studies are required to determine the pathogenesis, early detection, identification of patients who are at risk and to determine the most effective approaches to prophylaxis and treatment for HSV pneumonia.

    Pneumonia leads to considerable morbidity and mortality in nursing home residents with dementia. We assessed pneumonia incidence based on data from three different studies: (1) real-time national surveillance of healthcare-associated infections in nursing home residents in 2009-2015; (2) a randomized controlled trial in 2012-2015 to assess effects of a practical guideline in nursing home residents with dementia and pneumonia; and (3) a study in 2007-2010 to assess quality of dying in newly admitted nursing home residents with dementia. In national surveillance data, pneumonia incidence was calculated separately for psychogeriatric and somatic beds, as a proxy for residents with and without dementia. Weekly pneumonia incidence was significantly lower per 1000 psychogeriatric beds (3·9; 95% confidence interval (CI) 3·2-4·6) compared with 1000 somatic beds (5·7; 95% CI 5·1-6·3). Annual incidence per 1000 psychogeriatric beds was similar in national surveillance (range 78·9-117·1) and the trial (range 71·0-94·3), and significantly higher in newly admitted dementia residents (range 267·3-363·2). The incidence was highest during the first months after admission when compared with residents with longer stay. In conclusion, follow-up of pneumonia in newly admitted dementia residents may result in higher incidence, possibly due to higher risk in this population.

Os fatores de risco investigados foram variáveis relacionadas à história gestacional da mãe e ao nascimento da criança, às condições sociais da família e à utilização de serviços de saúde. Na primeira etapa de análise, através de um modelo de regressão logística univariada, foram estimados os coeficientes de cada variável independente, o risco relativo e seus limites de confiança. O peso ao nascer e a idade do desmame mostraram-se das mais fortemente associadas com a variável dependente. Na segunda etapa, foi feito o ajuste pelo modelo de regressão logística múltipla e somente 4 variáveis permaneceram estatisticamente associadas com a mortalidade: idade do desmame, peso ao nascer, número de moradores da casa e aplicação da vacina BCG.

    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.

    To investigate the relationship of pathogen DNA copies with clinic and laboratory features among children with Mycoplasma pneumoniae (MP) pneumonia. A total of 95 enrolled children with MP pneumonia were assigned into the high-MP-load group (>10 6 /mL) and the low-MP-load group (≤10 6 /mL) according to MP-DNA copies in bronchoalveolar lavage fluid (BALF). Clinical characteristics and any allergy history were collected. Aeroallergens and food allergens were detected with a skin test. Serum IgE and eosinophil cationic protein (ECP) were assessed using enzyme immunoassay. BALF levels of IL-4, IFN-γ, IL-8 and TNF-α were assessed by ELISA. Compared with the low-MP-load group, 72.7% in the high-MP-load group developed refractory MP pneumonia who failed to respond to at least 1-week treatment with macrolides (72.7% vs 41.9%, P = 0.005). More children in the high-load group than those in the low-load group presented with extrapulmonary manifestations, lung consolidation, pleural effusion and atopic conditions including any allergy history, positive findings of aeroallergen test and increased serum IgE and ECP (P  0.05). Atopy may be a risk factor for the presence and severity of refractory MP pneumonia due to the high pathogen load in airway. © 2016 John Wiley & Sons Ltd.

  10. Nonimaging aspects of follow-up in breast cancer reconstruction.

    Wood, W C

    1991-09-01

    Follow-up of patients with breast cancer is directed to the early detection of recurrent or metastatic disease and the detection of new primary breast cancer. The survival benefit of early detection is limited to some patients with local failure or new primary tumors. That imaging is not used in follow-up of patients who have had breast cancer reconstruction is related to possible interference with this putative benefit by the reconstructive procedure. Such follow-up is accomplished by the patient's own surveillance, clinical examination, and laboratory testing supplemented by imaging studies. Clinical follow-up trials of women who have undergone breast reconstructive surgery show no evidence that locally recurrent breast carcinoma is masked when compared with follow-up of women who did not undergo reconstructive procedures. Reshaping of the contralateral breast to match the reconstructed breast introduces the possibility of interference with palpation as well as mammographic distortion in some women. This is an uncommon practical problem except when complicated by fat necrosis.

    Full Text Available Outcomes of III-VI AB degree burns in children,regardless of the nature of treatment in the acute andrecovery period, are the development of scar contractures and deformities of the joints. However, thecorrect organization of follow-up care and rehabilitation treatment can significantly reduce the severity and facilitates the full recovery of the affected segment. Based on the analysis of their own material, the author defines the early stage of rehabilitation in these patients before full maturation of scar tissue or before the formation of functionally significant joint contractures, and later period, when there are indications for surgical rehabilitation. In the early period, follow-up care is recommended in 1 month after discharge and then on a quarterly basis, and with the appearance of deformities - at least once in 2 months. At the2nd stage of rehabilitation, older children and children of secondary school age are subject to follow-up care at least 1 time per year of primary school age - atleast once in 6 months, preschool children - every3 months. The proposed assessment of scar tissuehelps to determine the terms of follow-up care. Usingthis scheme of follow-up care and appropriate treatment allowed the author to obtain excellent and goodresults in 87-90 % of cases at the stages of rehabilitaion.

    All observations analyzed here were collected by the Kepler spacecraft with short-cadence exposures from 2012 to 2016. Full details of the raw and processed Kepler and K2 observations are summarized in Table2. We complemented our space-based photometry of these 27 pulsating hydrogen-atmosphere white dwarfs (DAVs) by determining their atmospheric parameters based on model-atmosphere fits to follow-up spectroscopy obtained from two 4m class, ground-based facilities. Spectra taken with the 4.2m William Herschel Telescope (WHT) on the island of La Palma cover roughly 3800-5100Å at roughly 2.0Å resolution; spanning 2013 Jun 06 to 2014 Jul 25. Spectra taken with the 4.1m Southern Astrophysical Research (SOAR) telescope on Cerro Pachon in Chile cover roughly 3600-5200Å; spanning 2014 Oct 13 to 2017 Apr 21. We detail these spectroscopic observations and their resultant fits in Table 3. (4 data files).

    To evaluate the rates of inferior vena cava (IVC) filter retrieval and the number of patient's lost to follow-up, before and after the establishment of an IVC filter database and interventional radiology (inserting physician) led follow-up. On the 1st of June 2012, an electronic interventional radiology database was established at our Institution. In addition, the interventional radiology team took responsibility for follow-up of IVC filters. Data were prospectively collected from the database for all patients who had an IVC filter inserted between the 1st June 2012 and the 31st May 2014. Data on patients who had an IVC filter inserted between the 1st of June 2009 to the 31st of May 2012 were retrospectively reviewed. Patient demographics, insertion indications, filter types, retrieval status, documented retrieval decisions, time in situ, trackable events and complications were obtained in the pre-database (n = 136) and post-database (n = 118) cohorts. Attempted IVC filter retrieval rates were improved from 52.9% to 72.9% (P = 0.001) following the establishment of the database. The number of patients with no documented decision (lost to follow-up) regarding their IVC filter reduced from 31 of 136 (23%) to 0 of 118 patients (P = database group (113 as compared to 137 days, P = 0.129). Following the establishment of an IVC filter database and interventional radiology led follow-up, we demonstrate a significant improvement in the attempted retrieval rates of IVC filters and the number of patient's lost to follow-up. © 2017 The Royal Australian and New Zealand College of Radiologists.

    Full Text Available Purpose: To explore the metabolic characterization of host responses to drainage-resistant Klebsiella pneumoniae liver abscesses (DRKPLAs with serum 1H-nuclear magnetic resonance (NMR spectroscopy.Materials and Methods: The hospital records of all patients with a diagnosis of a liver abscess between June 2015 and December 2016 were retrieved from an electronic hospital database. Eighty-six patients with Klebsiella pneumoniae (K. pneumoniae liver abscesses who underwent percutaneous drainage were identified. Twenty patients with confirmed DRKPLAs were studied. Moreover, we identified 20 consecutive patients with drainage-sensitive Klebsiella pneumoniae liver abscesses (DSKPLAs as controls. Serum samples from the two groups were analyzed with 1H NMR spectroscopy. Partial least squares discriminant analysis (PLS-DA was used to perform 1H NMR metabolic profiling. Metabolites were identified using the Human Metabolome Database, and pathway analysis was performed with MetaboAnalyst 3.0.Results: The PLS-DA test was able to discriminate between the two groups. Five key metabolites that contributed to their discrimination were identified. Glucose, lactate, and 3-hydroxybutyrate were found to be upregulated in DRKPLAs, whereas glutamine and alanine were downregulated compared with the DSKPLAs. Pathway analysis indicated that amino acid metabolisms were significantly different between the DRKPLAs and the DSKPLAs. The D-glutamine and D-glutamate metabolisms exhibited the greatest influences.Conclusions: The five key metabolites identified in our study may be potential targets for guiding novel therapeutics of DRKPLAs and are worthy of additional investigation.

    2013-10-01

    Organising pneumonia (otherwise referred to as bronchiolitis obliterans organising pneumonia) is characterised histologically by plugs of granulation tissue, which are present predominantly within small airways, alveolar ducts and peri-bronchiolar alveoli. This pattern is not specific for any disorder or cause, but is one type of inflammatory response to pulmonary injury, which may be seen in a wide variety of clinical conditions. Typically, organising pneumonia responds very well to corticosteroid treatment; however, a small percentage of patients appear to develop progressive fibrosis.

  18. Significance of anaerobes and oral bacteria in community-acquired pneumonia.

    Directory of Open Access Journals (Sweden)

    Kei Yamasaki

    Full Text Available BACKGROUND: Molecular biological modalities with better detection rates have been applied to identify the bacteria causing infectious diseases. Approximately 10-48% of bacterial pathogens causing community-acquired pneumonia are not identified using conventional cultivation methods. This study evaluated the bacteriological causes of community-acquired pneumonia using a cultivation-independent clone library analysis of the 16S ribosomal RNA gene of bronchoalveolar lavage specimens, and compared the results with those of conventional cultivation methods. METHODS: Patients with community-acquired pneumonia were enrolled based on their clinical and radiological findings. Bronchoalveolar lavage specimens were collected from pulmonary pathological lesions using bronchoscopy and evaluated by both a culture-independent molecular method and conventional cultivation methods. For the culture-independent molecular method, approximately 600 base pairs of 16S ribosomal RNA genes were amplified using polymerase chain reaction with universal primers, followed by the construction of clone libraries. The nucleotide sequences of 96 clones randomly chosen for each specimen were determined, and bacterial homology was searched. Conventional cultivation methods, including anaerobic cultures, were also performed using the same specimens. RESULTS: In addition to known common pathogens of community-acquired pneumonia [Streptococcus pneumoniae (18.8%, Haemophilus influenzae (18.8%, Mycoplasma pneumoniae (17.2%], molecular analysis of specimens from 64 patients with community-acquired pneumonia showed relatively higher rates of anaerobes (15.6% and oral bacteria (15.6% than previous reports. CONCLUSION: Our findings suggest that anaerobes and oral bacteria are more frequently detected in patients with community-acquired pneumonia than previously believed. It is possible that these bacteria may play more important roles in community-acquired pneumonia.

  19. Severe Community-acquired Pneumonia Due to Legionella pneumophila Serogroup 6

    Full Text Available Legionella pneumophila is a common cause of sporadic community-acquired pneumonia, but culture-proven legionellosis is rarely diagnosed. There is no laboratory test for Legionnaires' disease that can detect all patients with the disease. Culture is the standard diagnostic method and should be initiated as soon as possible in suspected cases. We describe a rare case of community-acquired pneumonia caused by L. pneumophila serogroup 6. A 77-year-old man was admitted to a tertiary care hospital because of high fever, productive cough, and progressive dyspnea. Chest radiography showed bilateral pneumonia, which led to respiratory failure necessitating mechanical ventilatory support. Despite antibiotic therapy, his condition continued to deteriorate and acute renal failure also developed. Urine was negative for L. pneumophila. Culture of the sputum yielded L. pneumophila serogroup 6, although there was no elevation of the serum antibody titer. Pneumonia resolved gradually and he was extubated after treatment with levofloxacin followed by erythromycin. L. pneumophila other than serogroup 1 should be included in the differential diagnosis of patients with suspected atypical community-acquired pneumonia.

    The burden and epidemiology of Mycoplasma pneumoniae (Mp) among U.S. children (<18 years) hospitalized with community-acquired pneumonia (CAP) are poorly understood. In the Etiology of Pneumonia in the Community (EPIC) study, we prospectively enrolled 2254 children hospitalized with radiographically-confirmed pneumonia from January 2010-June 2012 and tested nasopharyngeal/oropharyngeal swabs for Mp using real-time polymerase chain reaction (PCR). Clinical and epidemiological features of Mp-PCR-positive and -negative children were compared using logistic regression. Macrolide susceptibility was assessed by genotyping isolates. In the EPIC study, 182(8%) children were Mp-PCR-positive (median age: 7 years); 12% required intensive care and 26% had pleural effusion. No in-hospital deaths occurred. Macrolide resistance was found in 6/169(4%) isolates. Of 178(98%) Mp-PCR-positive children tested for co-pathogens, 50(28%) had ≥1 co-pathogen detected. Variables significantly associated with higher odds of Mp detection included age {10-17 years [adjusted odds ratio (aOR): 7.9 (95% confidence interval (CI): 4.5-13.6)] and 5-9 years [aOR: 4.8 (CI: 2.9-7.8)] vs. 2-4 years}, outpatient antibiotics ≤5 days pre-admission [aOR: 2.3 (CI: 1.5-3.4)], and co-pathogen detection [aOR: 2.1 (CI: 1.3-3.1)]. Clinical characteristics often seen included hilar lymphadenopathy, rales, headache, sore throat, and decreased breath sounds. Usually considered as a mild respiratory infection, M. pneumoniae was the most commonly detected bacteria among children ≥5 years hospitalized with CAP; one-quarter of whom had co-detections. Although associated with clinically non-specific symptoms, there was a need for intensive care support in some cases. M. pneumoniae should be included in the differential diagnosis for school-aged children hospitalized with CAP.

    When tuberculous pneumonia appears as a segmental or loabr consolidation, its is difficult to differentiate tuberculous pneumonia from nontuberculous bacterial pneumonia radiologically. The object of this study was to define the typical radiographic findings of tuberculous pneumonia through comparative analysis of tuberculous and nontuberculous pneumonia. A review of chest radiolograph in 29 patients with tuberculous pneumonia and in 23 patients with nontuberculous bacterial pneumonia was made with regard to homogeneity, volume loss, air-fluid level within the cavities, air-bronchogram, pleural disease, and predilection sites. The characteristic findings of tuberculous pneumonia are a heterogeneous density of infiltration (66%), evidence of volume loss of infiltrative lesion (52%), and cavity formation (48%) without air - fluid level. An associated parameter of analysis is the relative absence of leukocytosis (76%)

In this context, several bacteria have the ability to develop mechanisms of enzymatic resistance, mainly Enterobacteriaceae. In this family of microorganisms, the production of Klebsiella pneumoniae carbapenemase (KPC is an emerging mechanism, which should be under constant observation. MATERIAL AND METHOD: This study investigated the phenotype of KPC in 30 clinical isolates of Enterobacteriaceae resistant to third generation cephalosporin and carbapenem from two hospitals (Porto Alegre city and Porto Alegre, RS. It was performed disk diffusion method with imipenem, meropenem and ertapenem. Additionally, 14 strains with halo < 22 mm for the last antimicrobial agent underwent modified Hodge test. RESULTS: No sample showed carbapenemase (Hodge negative. DISCUSSION: Despite the fact there was no carbapenemase, resistance to carbapenems is possibly attributed to the presence of beta-lactamases AmpC and/or ESBL associated with changes in the permeability of porin channels. CONCLUSION: Given the emerging nature of KPC, it is important to trace it in Enterobacteriaceae

    Between 1983 and 1996, a series of 240 patients with early stage breast cancer were treated with breast conservative treatment, and 201 patients of them all received irradiation at a dose of 46-60 Gy to the affected breast. Among the 201 patients who received breast irradiation, four (2.0%) patients experienced radiation pneumonia. These four patients with radiation pneumonia presented with coughing from 7 to 20 weeks after irradiation. Chest X-ray film revealed interstitial pneumonia in a lung field where coincided with the irradiated field in them. Three out of four patients demanded steroids, but all patients got well within 4 months. Radiation pneumonia following conservative surgery and radiotherapy for breast cancer is an infrequent complication, but attention should be paid to radiation pneumonia if the patient suffers from persistent coughing after radiotherapy.

    Objective: To evaluate the role of MRI water-sensitive sequences in the differential diagnosis between pneumonia-like mucinous adenocarcinoma and infectious pneumonia. Subjects and methods: Twenty-three patients with pneumonia-like mucinous adenocarcinoma and 30 patients with infectious pneumonia underwent computed tomography (CT) and MRI. Two blinded and independent readers evaluated CT and MR images using a 3-level confidence scale in two separate sessions. Results were tested for statistical significance using the Fisher's exact test and the Cohen's k test. Results: On CT, the two readers respectively made correct diagnoses of mucinous adenocarcinoma in 17 out of 23 cases (73.9%), and in 15 out of 23 cases (65.2%). A correct diagnosis of infectious pneumonia was made in 22 out of 30 cases (73.3%), and in 24 out of 30 cases (80.0%). On MRI, both readers made correct diagnoses of mucinous adenocarcinoma in 23 out of 23 (100%) cases, and of infectious pneumonia in 30 out of 30 (100%) cases. Fisher's exact test showed a significant difference in the diagnosis of mucinous adenocarcinoma between MRI and CT for both readers, P = 0.01 for reader 1 and P = 0.002 for reader 2, respectively. A good agreement (k = 0.73) was found between the two readers on CT evaluation, whereas an almost perfect agreement (k = 1.00) was found for MRI. Conclusions: MRI with 'water-sensitive' sequences should be added in the diagnostic protocol of every patient with pulmonary consolidation suspected to be mucinous adenocarcinoma.

    Objectives Long-term outcomes following traumatic brain injury (TBI) correlate with initial head injury severity and other acute factors. Hospital-acquired pneumonia (HAP) is a common complication in TBI. Little information exists regarding the significance of infectious complications on long-term outcomes post-TBI. We sought to characterize risks associated with HAP on outcomes 5 years post-TBI. Methods Ddata from the merger of an institutional trauma registry and the TBI Model Systems outcome data. Individuals with severe head injuries (Abbreviated Injury Scale≥4), who survived to rehabilitation were analyzed. Primary outcome was Glasgow Outcome Scaled-Extended (GOSE) at 1, 2, and 5 years. GOSE was dichotomized into LOW (GOSEGOSE≥6). Logistic regression was utilized to determine adjusted odds of LOW-GOSE associated with HAP after controlling for age, sex, head and overall injury severity, cranial surgery, Glasgow Coma Scale (GCS), ventilation days, and other important confounders. A general estimating equation (GEE) model was used to analyze all outcome observations simultaneously while controlling for within-patient correlation. Results A total of 141 individuals met inclusion criteria, with a 30% incidence of HAP. Individuals with and without HAP had similar demographic profiles, presenting vitals, head injury severity, and prevalence of cranial surgery. Individuals with HAP had lower presenting GCS. Logistic regression demonstrated that HAP was independently associated with LOW-GOSE scores at follow-up (1year: OR=6.39, 95%CI: 1.76-23.14, p=0.005; 2-years: OR=7.30, 95%CI 1.87-27.89, p=0.004; 5-years: OR=6.89, 95%CI: 1.42-33.39, p=0.017). Stratifying by GCS≤8 and early intubation, HAP remained a significant independent predictor of LOW-GOSE in all strata. In the GEE model, HAP continued to be an independent predictor of LOW-GOSE (OR: 4.59; 95%CI: 1.82-11.60′ p=0.001). Conclusion HAP is independently associated with poor outcomes in severe-TBI extending 5

    Full Text Available The aim of this study was to investigate the IgM antibody positivities of atypical pneumonia agents in patients with community-acquired pneumonia (CAP, and to compare the results with controls. The serum samples which were collected from 87 adult patients and 21 healthy controls have been investigated by a commercial ELISA (Pneumobact ELISA IgM, Vircell, Spain in which four different atypical pneumonia agents were fixed onto a slide. In the patients group, IgM positivity rates for the agents were as follows, respectively; 2.3% for Legionella pneumophila, 56.3% Chlamydia pneumoniae, 33.3% for Mycoplasma pneumoniae, 9.2% for Coxiella burnetii. The rates of IgM positivities in the control group varied 7% for all of the agents except M. Pneumoniae and C. Pneumoniae and 2 of these controls were positive for L. Pneumophila IgM, one was positive for C. Burnetii IgM. According to the statistical evaluation, there were significant differences for IgM seropositivities to Mycoplasma pneumoniae and Chlamydia Pneumoniae,between the patient and the control groups (p0.05. We showed that the seropositivity rate of atypical agents in patients with CAP was significantly higher when compared to healthy control group. This result suggests us, atypical agents might be responsible in CAP patients in a great amount. Furthermore, our study also suggests that clinical and radiological findings are not useful for discriminating atypical from typical pneumonia. [TAF Prev Med Bull 2007; 6(4.000: 279-284

    To evaluate reasons for non-compliance with post-cataract surgical follow-up in rural China, and assess the impact of incentives on improving compliance. Patients having undergone cataract surgery more than 3 months previously at cataract surgery training hospitals in Guangdong were invited by telephone and advertisements to a hospital-based study examination, with compensation for travel costs (US$7). Information on prior post-surgical follow up was collected by questionnaire at the hospital or by telephone. Logistic regression was used to assess predictors of post-operative attendance with or without compensation. Among 518 eligible patients, 426 (82.2%) underwent interviews and 342 (66.0%) attended the compensated study examination. Ninety nine participants (23.2%) reported previously returning for uncompensated follow-up ≥ 3 months post-operatively, and 225 (52.8%) had returned for any prior post-operative examination. Uncompensated follow-up at ≥ 3 months was associated with higher income (P = 0.037), and recalling instruction by a doctor to follow-up (P = 0.001), while age, gender, travel cost, and post-operative satisfaction and vision were not associated. Younger (P = 0.002) patients and those reporting being instructed to follow up (P = 0.008) were more likely to return for the compensated research examination. Among all interviewed subjects, only 170 (39.9%) reported knowing they were to return to hospital. Modest compensation, advertisements and telephone contact can increase medium-term follow-up rates after cataract surgery by three-fold. Better communication of specific targets for follow-up may improve follow-up compliance.

    A long-term follow-up of echolalia and correct question answering was conducted for 6 subjects from three previously published studies. The follow-up periods ranged from 26 to 57 months. In a training site follow-up, subjects were exposed to baseline/posttraining conditions in which the original trainer and/or a novel person(s) presented trained and untrained questions. Four subjects displayed echolalia below baseline levels, and another did so in some assessments. Overall, echolalia was lowe...

    Isolated minor rib fractures (IMRFs) after blunt chest traumas are commonly observed in emergency departments. However, the relationship between IMRFs and subsequent pneumonia remains controversial. This nationwide cohort study investigated the association between IMRFs and the risk of pneumonia in patients with blunt chest traumas. Nationwide population-based cohort study. Patients with IMRFs were identified between 2010 and 2011 from the Taiwan National Health Insurance Research Database. Non-traumatic patients were matched through 1:8 propensity-score matching according to age, sex, and comorbidities (namely diabetes, hypertension, cardiovascular disease, asthma and chronic obstructive pulmonary disease (COPD)) with the comparison cohort. We estimated the adjusted HRs (aHRs) by using the Cox proportional hazard model. A total of 709 patients with IMRFs and 5672 non-traumatic patients were included. The primary end point was the occurrence of pneumonia within 30 days. The incidence of pneumonia following IMRFs was 1.6% (11/709). The aHR for the risk of pneumonia after IMRFs was 8.94 (95% CI=3.79 to 21.09, ppneumonia following IMRFs. In the IMRF group, presence of single or two isolated rib fractures was associated with an increased risk of pneumonia with aHRs of 3.97 (95% CI 1.09 to 14.44, ppneumonia following IMRFs is low, patients with two isolated rib fractures were particularly susceptible to pneumonia. Physicians should focus on this complication, particularly in elderly patients and those with COPD. Published by the BMJ Publishing Group Limited.

    The cost of providing medical care is ever-increasing but the resources available are at best static. Major savings can be made by reducing inappropriate investigations. Using serological testing for organisms causing atypical pneumonia as an example, we examined the appropriateness of requests and also physicians\\' understanding of the test. Of 119 patients tested, only 3 had titres indicative of acute infection. Most patients were tested within 2 days of hospital admission, before receipt of results excluding more likely diagnoses. Forty-five patients had no current or recent respiratory symptoms, in whom infection was highly unlikely. Titres were most often requested by the least experienced members of the clinical team. Of 70 patients with an acute illness in whom a definitive diagnosis, bacteriological or otherwise, was not made, in only 9 was a convalescent specimen sent for follow-up titres. Most requests for serology for organisms causing atypical pneumonia were inappropriate. Furthermore, in the majority of cases the test was incorrectly used.

    2016-05-01

    Diabetes insipidus is a rare but recognized complication of meningitis. The occurrence of diabetes insidipus has been previously attributed to Streptococcus pneumoniae (S. pneumoniae) in a handful of patients and only once within the pediatric subpopulation. We present the clinical course of a previously healthy 2-year, 8-month-old male child ultimately diagnosed with central diabetes insipidus (CDI) secondary to S. pneumoniae meningitis. Permanent CDI following S. pneumoniae meningitis is unique to our case and has not been previously described. Following the case presentation, we describe the etiology, pathophysiology, diagnosis, and treatment of CDI. The mechanism proposed for this clinical outcome is cerebral herniation for a sufficient duration and subsequent ischemia leading to the development of permanent CDI. Providers should be aware of CDI resulting from S. pneumoniae meningitis as prompt diagnosis and management may decrease the risk of permanent hypothalamo-pituitary axis damage.

    Objective: To investigate the correlation between post-stroke pneumonia and outcome in patients with acute brain infarction. Methods: Consecutive acute cerebral infarction patients who were hospitalized in Department of Neurology, Jinan Military General Hospital were prospectively recruited from August 2010 to August 2014. The baseline data including age, sex, the National Institute of Health Stroke Scale (NIHSS) scores, type of Oxfordshire Community Stroke Project (OCSP: total anterior circulation infarct, partial anterior circulation infarct, posterior circulation infarct and lacunar infarct), fasting blood glucose etc. after admission were recorded. Post-stroke pneumonia was diagnosed by treating physician according to criteria for hospital-acquired pneumonia of the Centers for Disease Control and Prevention. Recovery was assessed by modified Rankin Scale (mRS) 180 days after stroke by telephone interview (mRS≤2 reflected good prognosis, and mRS>2 reflected unfavorable prognosis). Multinominal Logistic regression analysis, Kaplan-Meier curve and log rank test were used. Results: A total of 1 249 patients were enrolled, among them 173 patients were lost during follow-up. A total of 159 patients had post-stroke pneumonia, while 1 090 patients were without post-stroke. Compared with patients without post-stoke pneumonia, patients with post-stroke pneumonia were older (67±13 vs 63±12 years, P =0.000), more severe (NIHSS, 15(14) vs 4(4), P =0.000). Compared with patients without post-stoke pneumonia, more patients with post-stroke pneumonia suffered from heart failure (12.58% vs 3.40%, P =0.000), atrial fibrillation (26.42% vs 8.81%, P =0.000), myocardial infarction (10.06% vs 5.05%, P =0.016), recurrent brain infarction (30.19% vs 22.66%, P =0.045), total anterior circulation infarct type of OCSP (46.54% vs 19.63%, P =0.000), posterior circulation infarct of OCSP (39.62% vs 25.51%, P =0.001); more patients suffered from disorder of consciousness (60.38% vs 9

    Klebsiella pneumoniae has been considered as an important foodborne pathogen which causes severe infections that include meningitis, bronchitis, bacteremia, pneumonia, and urinary tract infections in humans and animals. It is well known to most clinicians as a cause of community-acquired bacterial pneumonia. Klebsiella is an opportunistic pathogen, that primarily attacks neonates, infants, elderly and immuno-compromised patients and therefore impose a serious, emerging public health hazard globally. Contaminated sprouts, vegetables, seafood and other animal meat products are considered as main sources of Klebsiella infection. In the current study, radiation sensitivity of K. pneumoniae MTCC 109 was determined in different food samples. The decimal reduction dose (D 10 ) values of K. pneumoniae MTCC 109 in saline and nutrient broth at 0–4 °C were 0.116±0.009, 0.136±0.005 kGy, respectively. The mixed sprouts, fish and poultry samples were inoculated with K. pneumoniae MTCC 109 and exposed to gamma radiation to evaluate the effectiveness of radiation treatment in the elimination of K. pneumoniae. D 10 values of K. pneumoniae in mixed sprouts, poultry and fish samples were found to be 0.142±0.009, 0.125±0.0004 and 0.277±0.012 kGy, respectively. Radiation treatment with a 1.5 kGy dose resulted in the complete elimination of 3.1±1.8×10 5 CFU/g of K. pneumoniae from these food samples. No recovery of K. pneumoniae was observed in the 1.5 kGy treated samples stored at 4 °C up to 12 days, even after enrichment and selective plating. This study shows that a 1.5 kGy dose of irradiation treatment could lead to the complete elimination of 3.1±1.8×10 5 CFU/g of K. pneumoniae from mixed sprouts, poultry and fish samples. - Highlights: • K. pneumoniae MTCC 109 is sensitive to gamma radiation. • D 10 values is in the range of 0.116–0.277 kGy. • Dose of 1.5 kGy reduced K. pneumonia from 3.1±1.8×10 5 CFU/g to undetectable. • No recovery of K. pneumoniae

    The diagnosis of community-acquired pneumonia (CAP) is often not possible based only on the clinical symptoms and biochemical parameters. For every patient with the suspicion of CAP, a chest radiograph in two planes should be carried out. Additionally, a risk stratification for the decision between outpatient therapy or hospitalization is recommended. Based on the evaluation of the different radiological patterns as well as their extent and distribution, a rough allocation to so-called pathogen groups as well as a differentiation between viral and bacterial infections are possible; however, because different pathogens cause different patterns an accurate correlation is not feasible by relying purely on imaging. The radiological findings serve as proof or exclusion of pneumonia and can also be used to evaluate the extent of the disease (e.g. monolobular, multilobular, unilateral or bilateral). In cases of prolonged disease, suspicion of complications (e.g. pleural effusion or empyema, necrotizing pneumonia or abscess) or comorbid conditions (e.g. underlying pulmonary or mediastinal diseases) computed tomography is an important diagnostic tool in addition to chest radiography. Ultrasound is often used to diagnose pleural processes (e.g. parapneumonic effusion or pleural empyema). (orig.) [German] Anhand der klinischen Symptome und laborchemischen Befundkonstellation alleine ist es oft nicht moeglich, die Diagnose einer ambulant erworbenen Pneumonie (''community-acquired pneumonia'', CAP) zu stellen.

Weiter muss eine Risikostratifizierung im Sinne der Entscheidung ambulante Therapie vs. Hospitalisierung erfolgen.

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

    Legionella pneumophila pneumonia (LPP) is of serious concern for chest physicians for its potential lethality and difficulty of diagnosis. In spite of widespread use of urine antigen detection method, it remains one of the most difficult-to-treat disease among community acquired pneumonia. We investigated CT images of 38 cases of LPP, comparing them with wide spread Streptococcus pneumoniae pneumonia (SPP). We find that sharply demarcated consolidation scattered in ground-glass opacity is the most striking and pathognomonic feature of LPP, which is rarely found in SPP. Bronchiolitis was not found in LPP, while it is a relatively common finding in SPP, which could be the second clue of differentiation of these two diseases. (author)

    Severe central nervous system diseases, such as encephalitis, have been reported in association with Mycoplasma pneumoniae infections. After an ENT infection, a 9-year-old boy with Down's syndrome developed encephalitis revealed by an acute alteration in consciousness. Head computed tomography showed, after 2 weeks, an infiltration in the basal ganglia region. The diagnosis of Mycoplasma pneumoniae encephalitis was made; recovery was complete in a few weeks. Mycoplasma pneumoniae infection should be considered in all cases of acute encephalopathy; yet the pathogenesis of the disorder is unknown and the treatment uncertain.

    Facebook (FB) use has grown exponentially over the past decade, including in rural areas. Despite its popularity, FB has been underutilized as a research follow-up approach to maintain contact with research participants and may have advantages in less densely populated areas and among more hard-to-reach, at-risk groups. The overall goal of this study was to examine FB as a supplemental follow-up approach to other follow-up strategies with rural drug-using women. Face-to-face interviews were conducted with randomly selected women who completed baseline interviews in 3 rural jails in 1 state. Analyses focus on participants who were released from jail and were eligible for 3-month follow-up (n = 284). Bivariate analyses were used to examine differences between FB users and nonusers, and multivariate logistic regression models examined predictors of 3-month follow-up participation and being located for follow-up using FB. About two-thirds (64.4%) of participants were regular FB users. Bivariate analyses indicated that FB users were younger, more educated, and more likely to have used alcohol in the 30 days before incarceration but less likely to have a chronic health problem. Regression analyses indicated that rural FB users had more than 5 times the odds of being located for the 3-month follow-up interview, even after controlling for other variables. There were no significant predictors of being followed up using FB. Findings suggest that FB is widely used and well accepted among rural drug-using women. Among hard-to-reach populations, including those in rural, geographically isolated regions, FB serves as a method to improve participant follow-up. © 2016 National Rural Health Association.

    Pneumonia epizootics are a major challenge for management of bighorn sheep (Ovis canadensis) affecting persistence of herds, satisfaction of stakeholders, and allocations of resources by management agencies. Risk factors associated with the disease are poorly understood, making pneumonia epizootics hard to predict; such epizootics are thus managed reactively rather than proactively. We developed a model for herds in Montana that identifies risk factors and addresses biological questions about risk. Using Bayesian logistic regression with repeated measures, we found that private land, weed control using domestic sheep or goats, pneumonia history, and herd density were positively associated with risk of pneumonia epizootics in 43 herds that experienced 22 epizootics out of 637 herd-years from 1979–2013. We defined an area of high risk for pathogen exposure as the area of each herd distribution plus a 14.5-km buffer from that boundary. Within this area, the odds of a pneumonia epizootic increased by >1.5 times per additional unit of private land (unit is the standardized % of private land where global  = 25.58% and SD = 14.53%). Odds were >3.3 times greater if domestic sheep or goats were used for weed control in a herd's area of high risk. If a herd or its neighbors within the area of high risk had a history of a pneumonia epizootic, odds of a subsequent pneumonia epizootic were >10 times greater. Risk greatly increased when herds were at high density, with nearly 15 times greater odds of a pneumonia epizootic compared to when herds were at low density. Odds of a pneumonia epizootic also appeared to decrease following increased spring precipitation (odds = 0.41 per unit increase, global  = 100.18% and SD = 26.97%). Risk was not associated with number of federal sheep and goat allotments, proximity to nearest herds of bighorn sheep, ratio of rams to ewes, percentage of average winter precipitation, or whether herds were of native versus mixed

    Pneumonia is a common and potentially serious illness. Corticosteroids have been suggested for the treatment of different types of infection, however their role in the treatment of pneumonia remains unclear. This is an update of a review published in 2011. To assess the efficacy and safety of corticosteroids in the treatment of pneumonia. We searched the Cochrane Acute Respiratory Infections Group's Specialised Register, CENTRAL, MEDLINE, Embase, and LILACS on 3 March 2017, together with relevant conference proceedings and references of identified trials. We also searched three trials registers for ongoing and unpublished trials. We included randomised controlled trials (RCTs) that assessed systemic corticosteroid therapy, given as adjunct to antibiotic treatment, versus placebo or no corticosteroids for adults and children with pneumonia. We used standard methodological procedures expected by Cochrane. Two review authors independently assessed risk of bias and extracted data. We contacted study authors for additional information. We estimated risk ratios (RR) with 95% confidence intervals (CI) and pooled data using the Mantel-Haenszel fixed-effect model when possible. We included 17 RCTs comprising a total of 2264 participants; 13 RCTs included 1954 adult participants, and four RCTs included 310 children. This update included 12 new studies, excluded one previously included study, and excluded five new trials. One trial awaits classification.All trials limited inclusion to inpatients with community-acquired pneumonia (CAP), with or without healthcare-associated pneumonia (HCAP). We assessed the risk of selection bias and attrition bias as low or unclear overall. We assessed performance bias risk as low for nine trials, unclear for one trial, and high for seven trials. We assessed reporting bias risk as low for three trials and high for the remaining 14 trials.Corticosteroids significantly reduced mortality in adults with severe pneumonia (RR 0.58, 95% CI 0.40 to 0

    Pathogens that cause pneumonia may be treated in a targeted fashion by antibiotics, but if this therapy fails, then treatment involves only nonspecific supportive measures, independent of the inciting infection. The purpose of this study was to determine whether host response is similar after disparate infections with similar mortalities. Prospective, randomized controlled study. Animal laboratory in a university medical center. Pneumonia was induced in FVB/N mice by either Streptococcus pneumoniae or two different concentrations of Pseudomonas aeruginosa. Plasma and bronchoalveolar lavage fluid from septic animals was assayed by a microarray immunoassay measuring 18 inflammatory mediators at multiple time points. The host response was dependent on the causative organism as well as kinetics of mortality, but the pro-inflammatory and anti-inflammatory responses were independent of inoculum concentration or degree of bacteremia. Pneumonia caused by different concentrations of the same bacteria, Pseudomonas aeruginosa, also yielded distinct inflammatory responses; however, inflammatory mediator expression did not directly track the severity of infection. For all infections, the host response was compartmentalized, with markedly different concentrations of inflammatory mediators in the systemic circulation and the lungs. Hierarchical clustering analysis resulted in the identification of five distinct clusters of the host response to bacterial infection. Principal components analysis correlated pulmonary macrophage inflammatory peptide-2 and interleukin-10 with progression of infection, whereas elevated plasma tumor necrosis factor sr2 and macrophage chemotactic peptide-1 were indicative of fulminant disease with >90% mortality within 48 hrs. Septic mice have distinct local and systemic responses to Streptococcus pneumoniae and Pseudomonas aeruginosa pneumonia. Targeting specific host inflammatory responses induced by distinct bacterial infections could represent a

  12. Towards increasing the utility of follow-up in Canadian EIA

    2005-01-01

    The importance of follow-up in the EIA process is clearly recognized in the Canadian Environmental Assessment Act (Act) in which, where it is considered appropriate, the responsible authority for a project will design a follow-up program and ensure its implementation. The Act is also explicit in recommending that the results of follow-up programs be used to improve the quality of environmental assessments (EAs). The purpose of this paper is to examine whether the specific requirements for follow-up under the Act in fact provide the best opportunity for such quality improvements. The definition of follow-up under the Act requires the verification of the accuracy of the environmental assessment and determination of the effectiveness of measures taken to mitigate the adverse environmental effects of a project. We argue that the Act, generally, and the requirements for follow-up specifically, adopts a negative perspective towards project effects by focusing on the mitigation of adverse effects and discourages the follow-up of important social or economic effects which are independent of project-related changes to the biophysical environment. Secondly, we argue that verification of accuracy places an unwarranted emphasis on 'what was expected' rather than on 'what was wanted' in terms of environmental outcomes. Using examples from Canadian experience, we illustrate the limitations of the current approach to follow-up and suggest that greater utility would be achieved by focusing on whether the environmental objectives of the project in question have been achieved

    To define a general methodology for maximising the success of follow-up processes for retrospective cohort studies in New Zealand, and to illustrate an approach to developing country-specific follow-up methodologies. We recently conducted a cohort study of mortality and cancer incidence in New Zealand professional fire fighters. A number of methods were used to trace vital status, including matching with records of the New Zealand Health Information Service (NZHIS), pension records of Work and Income New Zealand (WINZ), and electronic electoral rolls. Non-electronic methods included use of paper electoral rolls and the records of the Registrar of Births Deaths and Marriages. 95% of the theoretical person-years of follow-up of the cohort were traced using these methods. In terms of numbers of cohort members traced to end of follow-up, the most useful tracing methods were fire fighter employment records, the NZHIS, WINZ, and the electronic electoral rolls. The follow-up process used for the cohort study was highly successful. On the basis of this experience, we propose a generic, but flexible, model for follow-up of retrospective cohort studies in New Zealand. Similar models could be constructed for other countries. Successful follow-up of cohort studies is possible in New Zealand using established methods. This should encourage the use of cohort studies for the investigation of epidemiological issues. Similar models for follow-up processes could be constructed for other countries.

    Full Text Available Objective: To evaluate the clinical, laboratory, radiological, and demographic data of H3N2 pneumonia cases hospitalized to the Pulmonology Department during H3N2 pandemics and compare them with non-H3N2 community-acquired pneumonia (CAP cases. Methods: The study population consisted of all CAP cases hospitalized to our Pulmonology Department between December 2013 and February 2014 during the influenza outbreak. The patient files were evaluated for physical findings, laboratory data, radiological findings, and treatment and outcome of cases. H3N2 was diagnosed using polymerase chain reaction (PCR analysis of throat swabs. The clinical, radiological, and laboratory findings of H3N2 pneumonia cases were compared with those of non-H3N2 pneumonia cases. Mann–Whitney U test, Chi-square test, Fisher’s exact test, and logistic regression analysis by the forward step wise method were used for statistical analyses. P value0.05. The rates of treatment failure and/or transport to the intensive care unit with the need of invasive mechanical ventilation and mortality rates were also similar in both groups (p>0.05. Conclusion: H3N2 pneumonia/viral pneumonia is a member of CAP. Although the number of H3N2 cases are extremely small to draw a conclusion, the results of this study highlight that the clinical, radiological, and laboratory findings of H3N2 pneumonia cases are not different from those of non-H3N2 CAP cases.

  15. Regions on plasmid pCU1 required for the killing of Klebsiella pneumoniae.

    Plasmid pCU1 was Kik+ (promotes killing of Klebsiella pneumoniae). All Tn5 insertions within the tra region of pCU1 were Kik-. Two other regions, kikA and kikB, were needed. They may be separated on different plasmids, but both must be mobilized into Klebsiella pneumoniae. Establishment of one kik region in K. pneumoniae followed by receipt of the second did not lead to killing. Kik was therefore intracellular and required concerted and transient action of both regions.

    Full Text Available Introduction: Exogenous lipoid pneumonia (ELP is an uncommon condition resulting from aspirating or inhaling fatlike material. These substances elicit a foreign body reaction and proliferative fibrosis in the lung. Case report: We report a case of a 38-year-old woman with bilateral pulmonary infiltration. There were no clinical symptoms of this infiltration at diagnosis. The infiltration was found coincidentally during the pre-operation examination before surgery. A chest computed tomography scan revealed bilateral lung consolidation, particularly in the S6 area on the right side. The transthoracic lung biopsy led to suspicion of ELP. Precise anamnesis confirms the diagnosis of ELP caused by chronic improper use of baby body oil. Two years after discontinuing “baby body oil therapy”, a chest CT scan revealed partial regression of pulmonary infiltration. Conclusion: The diagnosis of exogenous lipoid pneumonia is often difficult as symptoms, signs, and radiographic findings are all rather non-specific. We would like to emphasize the role of precise case history in better identification of ELP.

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

    Fasciolia spp. are common trematode infestations worldwide. Fasciolia spp. may lead to hepatic diseases in the acute phase and may cause biliary diseases in the chronic phase. In addition, Fasciolia spp. may rarely cause extrahepatic signs and symptoms. The clinical manifestations of fascioliasis are divided into three groups: typical, atypical, and ectopic. Eosinophilic pneumonia is an atypical presentation of acute fascioliasis and it has been reported very rarely. Herein, we report a boy with marked blood eosinophilia and eosinophilic pneumonia who was diagnosed with fascioliasis by serologic tests and abdominal USG. The patient recovered completely following triclabendazole treatment.

    Clostridium difficile infection (CDI) is one of the most common gastrointestinal complication after antimicrobial treatment. It is estimated that CDI after pneumonia treatment is connected with a higher mortality than other causes of hospitalization. The aim of the study was to assess the relationship between the kind of antibiotic used for pneumonia treatment and mortality from post-pneumonia CDI. We addressed the issue by examining retrospectively the records of 217 patients who met the diagnostic criteria of CDI. Ninety four of those patients (43.3 %) came down with CDI infection after pneumonia treatment. Fifty of the 94 patients went through severe or severe and complicated CDI. The distribution of antecedent antibiotic treatment of pneumonia in these 50 patients was as follows: ceftriaxone in 14 (28 %) cases, amoxicillin with clavulanate in 9 (18 %), ciprofloxacin in 8 (16.0 %), clarithromycin in 7 (14 %), and cefuroxime and imipenem in 6 (12 %) each. The findings revealed a borderline enhancement in the proportion of deaths due to CDI in the ceftriaxone group compared with the ciprofloxacin, cefuroxime, and imipenem groups. The corollary is that ceftriaxone should be shunned in pneumonia treatment. The study demonstrates an association between the use of a specific antibiotic for pneumonia treatment and post-pneumonia mortality in patients who developed CDI.

    A comprehensive clinicoroentgenological study was used to examine 494 patients with chronic pneumonia. Morphological and functional changes observed in the pulmonary pare and functional changes observed in the pulmonary parenchyma and bronchial tree were studied. Types of pneumosclerosis, tigns of exacerbation of chronic pneumonia and abscess formation, morphological and functional disorders of bronchial penetrability in the pneumonic zone were described. Three forms of chronic pneumonia: bronchial, bronchiectatic and abscessing are signled out. The bronchial form is subdivided into chronic pneumonia with chronic bronchitis without deformity and wi.th deforming chronic bronchitis. In the bronchiectatic form pneumonia can be with cylindrical, saccular and cyst-like bronchiectasia. The general diagnosis of chronic pneumonia is established clinically depending on type and variants in 89-94% of cases, by X-ray and sonographic findings in all patients; types and variants of disease are most frequently defined after bronchography

    We evaluated the radiographic and high resolution CT findings in fifteen patients with biopsy proven nonspecific interstitial pneumonia. The most common radiographic findings in NSIP were bilateral infiltrates involving alveolar pattern, interstitial pattern, and mixed alveolar-interstitial pattern, which distributed mainly in the middle and lower lung zones. Loss of lung volumes were common. The predominant findings of linear and reticular opacities on HRCT were peribronchovascular interstitial thickening, parenchymal bands, intralobular interstitial thickening, and traction bronchiectasis. Honeycombing was not noted in any patient on initial CT scans. The predominant findings of increased lung opacity were mixed pattern of ground glass opacity and consolidation. Because these findings mimic those of idiopathic pulmonary fibrosis/usual interstitial pneumonia, distinction between NSIP and IPF/UIP seems to be difficult by radiographic and HRCT findings. The response to corticosteroid therapy was good. At follow up HRCT, the pulmonary abnormalities observed on initial scans had disappeared or were diminished in most cases. Intralobular interstitial thickening and traction bronchiectasis, that have been considered to be an indicator of irreversible fibrosis, occasionally disappeared after corticosteroid therapy.

  10. Pneumonia's second wind? A case study of the global health network for childhood pneumonia.

    2016-04-01

    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.

    A recent open-label pilot study (N = 15) found that two to three moderate to high doses (20 and 30 mg/70 kg) of the serotonin 2A receptor agonist, psilocybin, in combination with cognitive behavioral therapy (CBT) for smoking cessation, resulted in substantially higher 6-month smoking abstinence rates than are typically observed with other medications or CBT alone. To assess long-term effects of a psilocybin-facilitated smoking cessation program at ≥12 months after psilocybin administration. The present report describes biologically verified smoking abstinence outcomes of the previous pilot study at ≥12 months, and related data on subjective effects of psilocybin. All 15 participants completed a 12-month follow-up, and 12 (80%) returned for a long-term (≥16 months) follow-up, with a mean interval of 30 months (range = 16-57 months) between target-quit date (i.e., first psilocybin session) and long-term follow-up. At 12-month follow-up, 10 participants (67%) were confirmed as smoking abstinent. At long-term follow-up, nine participants (60%) were confirmed as smoking abstinent. At 12-month follow-up 13 participants (86.7%) rated their psilocybin experiences among the five most personally meaningful and spiritually significant experiences of their lives. These results suggest that in the context of a structured treatment program, psilocybin holds considerable promise in promoting long-term smoking abstinence. The present study adds to recent and historical evidence suggesting high success rates when using classic psychedelics in the treatment of addiction. Further research investigating psilocybin-facilitated treatment of substance use disorders is warranted.

    Pneumonia is a leading cause of morbidity and mortality in children. It is important to identify the clinical symptoms and physical examination findings associated with pneumonia to improve timely diagnosis, prevent significant morbidity, and limit antibiotic overuse. To systematically review the accuracy of symptoms and physical examination findings in identifying children with radiographic pneumonia. MEDLINE and Embase (1956 to May 2017) were searched, along with reference lists from retrieved articles, to identify diagnostic studies of pediatric pneumonia across a broad age range that had to include children younger than age 5 years (although some studies enrolled children up to age 19 years); 3644 unique articles were identified, of which 23 met inclusion criteria. Two authors independently abstracted raw data and assessed methodological quality. A third author resolved disputes. Likelihood ratios (LRs), sensitivity, and specificity were calculated for individual symptoms and physical examination findings for the diagnosis of pneumonia. An infiltrate on chest radiograph was considered the reference standard for the diagnosis of pneumonia. Twenty-three prospective cohort studies of children (N = 13 833) with possible pneumonia were included (8 from North America), with a range of 78 to 2829 patients per study. The prevalence of radiographic pneumonia in North American studies was 19% (95% CI, 11%-31%) and 37% (95% CI, 26%-50%) outside of North America. No single symptom was strongly associated with pneumonia; however, the presence of chest pain in 2 studies that included adolescents was associated with pneumonia (LR, 1.5-5.5; sensitivity, 8%-14%; specificity, 94%-97%). Vital sign abnormalities such as fever (temperature >37.5°C [LR range, 1.7-1.8]; sensitivity, 80%-92%; specificity, 47%-54%) and tachypnea (respiratory rate >40 breaths/min; LR, 1.5 [95% CI, 1.3-1.7]; sensitivity, 79%; specificity, 51%) were not strongly associated with pneumonia diagnosis

    The value of routine timed barium esophagram (TBE) in longitudinal follow-up of achalasia after Heller myotomy is unknown. We prospectively prescribed a yearly follow-up TBE. Purposes were to characterize esophageal emptying over time after myotomy, identify preoperative TBE measures associated with follow-up TBE, and characterize follow-up TBE over time in relationship to reintervention. From March 1995 to April 2013, 635 patients underwent Heller myotomy for achalasia; 559 had at least 1 follow-up TBE. Temporal trends of 1335 follow-up TBEs in all nonreintervention and reintervention patients were assessed. Multivariable longitudinal analysis identified preoperative TBE measures associated with follow-up TBE. On average, TBE height and width at 1 and 5 minutes decreased approximately 50% and 60%, respectively, at first postoperative follow-up, and remained stable or slightly decreased for up to 5 years. Wider TBE width at 5 minutes was associated with greater follow-up TBE height and width at 1 minute. Of 118 patients undergoing reintervention, 64 (57%) had only 1 reintervention, with follow-up TBE returning to that of nonreintervention patients. Patients whose follow-up TBE remained abnormal underwent a further reintervention, some normalizing on subsequent TBE, and some not. Follow-up TBE is valuable postmyotomy, particularly if there is substantial esophageal dilatation preoperatively. Follow-up TBE reassures patients with stable or decreasing TBE measures, permitting decreased follow-up intensity. Reintervention should not be considered a myotomy failure, because a successful, single, nonsurgical reintervention often results in long-term successful palliation. More than 1 reintervention requires intensification of TBE follow-up, facilitating treatment planning. Copyright © 2018 The American Association for Thoracic Surgery. Published by Elsevier Inc.

    Pneumonia is the third most common postoperative complication. However, its epidemiology varies widely and is often difficult to assess. For a better understanding, we utilized two national databases to determine the incidence of postoperative pneumonia after various surgical procedures. Specifically, we used the American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) and the Nationwide Inpatient Sample (NIS) to determine the incidence and yearly trends of postoperative pneumonia following orthopaedic, urologic, otorhinolaryngologic, cardiothoracic, neurosurgery, and general surgeries. The NIS and NSQIP databases from 2009-2013 were utilized. The Clinical Classification Software (CCS) for International Classification of Diseases, 9th edition (ICD-9) codes provided by the NIS database was used to identify all surgical subspecialty procedures. The incidence of postoperative pneumonia was identified as the total number of cases under each identifying CCS code that also had ICD-9 codes for postoperative pneumonia. In the NSQIP database, the surgical subspecialties were selected using the following identifying string variables provided by NSQIP: 1) "Orthopedics", 2) "Otolaryngology (ENT)", 3) "Urology", 4) "Neurosurgery", 5) "General Surgery", and 6) "Cardiac Surgery" and "Thoracic Surgery". Cardiac and thoracic surgery was merged to create the variable "Cardiothoracic Surgery". Postoperative pneumonia cases were extracted utilizing the available NSQIP nominal variables. All variables were used to isolate the incidences of postoperative pneumonia stratified by surgical specialty. A subsequent trend analysis was conducted to assess the associations between operative year and incidence of postoperative pneumonia. For all NIS surgeries, the incidence of postoperative pneumonia was 0.97% between 2009 and 2013. The incidence was highest among patients who underwent cardiothoracic surgery (3.3%) and urologic surgery (1.73%). Patients who

    To explore the extent of evidence-based data and cost-utility of follow-up after primary treatment of endometrial and ovarian cancer, addressing perspectives of technology, organization, economics, and patients. Systematic literature searches according to the recommendations of the Cochrane Handbook for Systematic Reviews of Interventions were conducted separately for each of the 4 perspectives. In addition, the organizational analysis included a nationwide questionnaire survey among all relevant hospital departments, and the operating costs were calculated. None of the identified studies supported a survival benefit from hospital-based follow-up after completion of primary treatment of endometrial or ovarian cancer. The methods for follow-up were of low technology (gynecologic examination with or without ultrasound examination). Other technologies had poor sensitivity and specificity in detecting recurrence. Small changes in applied technologies and organization lead to substantial changes in costs. Substantial differences especially in frequency and applied methods were found between departments. The literature review did not find evidence that follow-up affects the women's quality of life. The main purpose of follow-up after treatment of cancer is improved survival. Our review of the literature showed no evidence of a positive effect on survival in women followed up after primary treatment of endometrial or ovarian cancer. The conception of follow-up among physicians, patients, and their relatives therefore needs revision. Follow-up after treatment should have a clearly defined and evidence-based purpose. Based on the existing literature, this purpose should presently focus on other end points rather than early detection of relapse and improved survival. These end points could be quality of life, treatment toxicity, and economy.

    Full Text Available Background. To determinate the prevalence rates of Chlamydia pneumoniae infections in Slovenia and to evaluate the importance of C. pneumoniae infections at patients with community acquired pneumonia (CAP.Materials and methods. With the microimmunofluorescence test (micro-IF we evaluated the presence of C. pneumoniae specific antibodies in 1036 healthy subjects, in two periods of time, in 1991–93 and 1997–1998. We also tested the pair sera collected from 2118 patients with CAP between 1993–1999.Results. We demonstrated that C. pneumoniae infections are common in our population, as we detected IgG antibodies in 43.1% of healthy population. The prevalence rate of C. pneumoniae infections statistically significant increased in two periods of time. Acute C. pneumoniae infections were proved in 15.9% of all patients with CAP.Conclusions. C. pneumoniae is important respiratory pathogen also in our community. The infections are more common in older patients. Because C. pneumoniae like other Chlamydia species has tendency to cause chronic disease, it is reasonable to diagnose this bacterium in respiratory patients. It is also recommended to test convalescent sera at serologic laboratory diagnosis.

    Radiologic findings of 81 cases of acute, primary pneumonia in adolescence (in the twenties) were analyzed retrospectively with regard to their pattern, location, evolution and complication. The results were as follows: 1. The cases of single lesion were 85%, and multiple lesion 15%. 2. Left lower lobe was the most frequent site of involvement (42%), followed by right lower lobe (29%), right middle lobe (13%), left upper lobe (12.5%) and right upper lobe (4%) in the cases of single lesion. In cases of multiple lesions, lower lobe involvement was not so predominant as in cases of single lesion. 3. Most of the lesions were alveolar or bronchopneumonic in radiologic pattern. Interstitial pneumonic pattern was found in only 7 cases (9%). 4. Pleural effusion as associated finding was found in only 2 cases (2%). 5. Rapid radiographic improvement, short clinical course, complete healing, without residue when treated with broad spectrum antibiotics seem to be different findings as compared with secondary or elder group pneumonia

Studies conducted in developing countries indicate that the most serious symptoms of pneumonia are associated with bacterial causes, mainly Streptococcus pneumoniae, followed by Haemophilus influenzae type b. Managing those infections in children under two years of age is hindered by the lack of appropriate vaccines and by the decreased susceptibility of S. pneumoniae to penicillin and other antibiotics. In 1993, at the initiative of the Regional System for Vaccines of the Pan American Health Organization, and with funding from the Canadian International Development Agency, a study was designed to identify the S. pneumoniae capsular types that cause invasive disease in Latin American children under 5 years of age. The objective of the study was to determine the ideal composition of a conjugate vaccine that could be used in Latin America, and the penicillin susceptibility of the S. pneumoniae isolates. The initiative was undertaken in Argentina, Brazil, Chile, Colombia, Mexico, and Uruguay. This report analyzes the information that the participating countries generated on pneumococcal pneumonia. A total of 3 393 children were found with systemic S. pneumoniae infections, of which 1 578 corresponded to pneumonias. The analysis focused on 1 409 cases

    Full Text Available Neutrophil infiltration is the characteristic pathological feature of M. pneumoniae pneumonia (MPP. This study aimed to explore the associations among neutrophil activity, clinical presentation, and role of the M. pneumoniae/interleukin-8 (IL-8/neutrophil axis in the pathogenesis of MPP. A total of 42 patients with MPP were prospectively enrolled in the study. Neutrophil activity, including matrix metalloproteinase-9 (MMP-9, myeloperoxidase (MPO, and neutrophil elastase (NE, were measured. Clinical information was collected for all patients and control group. In vitro, IL-8 production was measured at different time points after M. pneumoniae infection of bronchial epithelial cells, and neutrophil activity was analyzed after IL-8 stimulation. The percentage of neutrophil in the bronchoalveolar lavage fluid was higher in the group of patients with high levels of M. pneumoniae DNA than in those with low levels of M. pneumoniae DNA (P < 0.05. IL-8, MMP-9, and NE in patients with MPP significantly increased compared with controls and decreased after treatment (P < 0.05. MPO and MMP-9 were associated with duration of fever (r = 0.332, P < 0.05 and length of stay (r = 0.342, P < 0.05, respectively. In vitro, M. pneumoniae induced IL-8 production by bronchial epithelial cells in a time dependent manner. MPO, MMP-9 and NE production by neutrophils significantly increased compared with medium controls after IL-8 stimulation. In summary, the M. pneumoniae/IL-8/neutrophil axis likely plays a vital role in the pathogenesis of MPP.

    Full Text Available The aim of our study was to obtain comprehensive insight into the bacteriological and clinical profile of community-acquired pneumonia requiring hospitalization. The patient population consisted of 100 patients admitted with the diagnosis of community-acquired pneumonia (CAP, as defined by British Thoracic society, from December 1998 to Dec 2000, at the Sher- i-Kashmir institute of Medical Sciences Soura, Srinagar, India. Gram negative organisms were the commonest cause (19/29, followed by gram positive (10/29. In 71 cases no etiological cause was obtained. Pseudomonas aeruginosa was the commonest pathogen (10/29, followed by Staphylococcus aureus (7/29, Escherichia coli (6/29, Klebsiella spp. (3/29, Streptococcus pyogenes (1/29, Streptococcus pneumoniae (1/29 and Acinetobacter spp. (1/29.

Fourteen patients, of whom, nine were males and five females, died. Staphylococcus aureus was the causative organism in four, Pseudomonas in two, Klebsiella in one, and no organism was isolated in seven cases. The factors predicting mortality at admission were - age over 62 years, history of COPD or smoking, hypotension, altered sensorium, respiratory failure, leucocytosis, and s0 taphylococcus pneumonia and undetermined etiology. The overall rate of identification of microbial etiology of community-acquired pneumonia was 29%, which is very low, and if serological tests for legionella, mycoplasma and viruses are performed the diagnostic yield would

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

    To evaluate the time to hospitalisation and baseline factors associated with pneumonia/choking in Parkinson's Disease (PD) patients. Although dysphagia and pneumonia are common problems in PD, scarce research has been performed. A total of 194 PD patients who underwent a VFS evaluation were retrospectively selected. The mode of feeding and admissions for pneumonia/choking were analyzed. Baseline clinical and demographic variables were compared between feeding groups. Kaplan-Meier survival analysis was performed to estimate time to pneumonia/choking. Clinical variables significantly associated with pneumonia/choking free survival were identified using Cox regression. Hospitalisation for pneumonia/choking occurred in 89 out of 194 patients, with the highest admission rate in rejected enteral feeding group (66.7%), followed by enteral feeding (61.8%) and oral feeding (38.8%) groups. The estimates of median time to event were 11, 14, and 47 months for rejected enteral feeding, enteral and oral feeding groups respectively (log-rank test p < 0.001). The rejected enteral feeding group had the highest risk of pneumonia/choking (HR 4.61, 95%CI:2.33-9.08, p < 0.001), followed by enteral feeding group (HR 2.29, 95%CI:1.25-4.19, p = 0.007), when compared to oral feeding group after adjusting for possible confounders. A stepwise Cox regression showed that the rejected enteral feeding (HR 4.89, 95%CI:2.19-10.88, p < 0.001), enteral mode of feeding (HR 2.43, 95%CI:1.11-5.32, p = 0.026), and Charlson weighted index of co-morbidity (HR 1.27, 95%CI:1.03-1.58, p = 0.028) were independently associated with higher hazard of pneumonia/choking. Compliance to feeding recommendations is important to reduce the risk of hospitalisation for pneumonia/choking. The recommended mode of feeding and comorbidity index was significantly associated with pneumonia/choking risk. Copyright © 2016 Elsevier Ltd. All rights reserved.

    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.

    This article not only reviews the essential aspects of community-acquired pneumonia for daily clinical practice, but also highlights the controversial issues and provides the newest available information. Community-acquired pneumonia is considered in a broad sense, without excluding certain variants that, in recent years, a number of authors have managed to delineate, such as healthcare-associated pneumonia. The latter form is nothing more than the same disease that affects more frail patients, with a greater number of risk factors, both sharing an overall common approach.

    All patients presented a fracture of the collum mandibulae, which had occurred between 1 and 10 years before treatment. The patients were exclusively treated conservatively. 57 of 67 patients did not indicate any subjective pain. 10 patients complained about pain and restricted movability. In only 22 cases no pathologic findings were obtained in the clinical follow-up examinations. In 33 patients the roentgenologic follow-up examination led to pathologic findings. Severe complications as disturbance of growth and formation of ankyloses, occurred only in one single case, due to a fracture of the mandibular joint in childhood. (orig./MG) [de

    Full text: Tumour ablation with radiofrequency (RF) energy is a relatively new procedure for the treatment of focal malignant disease. Several published trials show the benefit of this procedure in the treatment of malignant liver lesions, however, there are few trials on the benefits of treating pulmonary metastases in this way. The first 14 patients having RF ablation of pulmonary metastases from colorectal cancer (CRC) have been followed. 11 had their RF ablation performed at St George Public Hospital under CT fluoroscopy, 3 under fluoroscopy at St George Private Hospital. Complications from the procedure are described, as well as follow up appearances and results. The only significant complications described so far are five pneumothoraces, three requiring treatment with one needing extended hospital admission. Intraprocedural parenchymal haemorrhage, and changes of consolidation in surrounding lung not causing significant clinical symptoms were also found. One case of post procedure pneumonia occurred. Minor haemoptysis also occurred. Successfully ablated lesions show and increase in size in the one week and one month CT scans, but then progressively fall in size. Some show cavitation, which resolves. No significant detrimental impact on quality of life has so far been found, but medium and long-term effects are yet to be studied. RF ablation of pulmonary metastases from CRC, while still at its early stages, shows promise as a possible second line treatment (with other adjuvant therapy) for the management of focal malignant disease in the lung. CT fluoroscopy/fluoroscopy is a viable method for electrode placement and is performed this way at our institution. Copyright (2002) Blackwell Science Pty Ltd

    Full Text Available OBJETIVO: Investigar os efeitos causados pela poluição atmosférica na morbidade por pneumonia e por gripe em idosos entre 1996 e 1998. MÉTODOS: Foram obtidos dados diários de atendimentos por pneumonia e gripe para idosos em pronto-socorro médico de um hospital-escola de referência no Município de São Paulo, SP, Brasil. Os níveis diários de CO, O3, SO2, NO2 e PM10 foram obtidos na Companhia de Tecnologia de Saneamento Ambiental, e os dados diários de temperatura e umidade relativa do ar foram obtidos no Instituto Astronômico e Geofísico da USP. Para verificar a relação existente entre pneumonia e gripe e poluição atmosférica, utilizou-se o modelo aditivo generalizado de regressão de Poisson, tendo como variável dependente o número diário de atendimentos por pneumonia e gripe e como variáveis independentes as concentrações médias diárias dos poluentes atmosféricos. A análise foi ajustada para sazonalidade de longa duração (número de dias transcorridos, sazonalidade de curta duração (dias da semana, temperatura mínima, umidade média, períodos de rodízio e os atendimentos por doenças não-respiratórias em idosos. RESULTADOS: O3 e SO2 estão diretamente associados à pneumonia e à gripe, independentemente das variáveis de controle. Porém, na análise conjunta, eles perdem sua significância estatística. Pôde-se observar que um aumento interquartil (25%-75% para o O3 (38,80 mig/m³ e SO2 (15,05 mig/m³ levaram a um acréscimo de 8,07% e 14,51%, respectivamente, no número de atendimentos por pneumonia e gripe em idosos. CONCLUSÕES: Os resultados sugerem que a poluição atmosférica promove efeitos adversos para a saúde de idosos.

    To identify the most common pneumococcal serotypes in children hospitalized with invasive pneumonia, correlate isolated serotypes with those included in conjugate vaccines, and ascertain the sensitivity of the isolated pneumococcal strains to penicillin and other antibiotics. From January 2003 to October 2008, a retrospective study of hospitalized children with a diagnosis of Streptococcus pneumoniae pneumonia was conducted at the university hospital of Universidade de São Paulo. Criteria for inclusion were: age greater than 29 days and less than 15 years, radiological and clinical diagnosis of pneumonia, and isolation of Streptococcus pneumoniae in blood cultures and/or pleural effusion. The study included 107 children. The most common serotypes were 14 (36.5%), 1 (16%), 5 (14.6%), 6B (6.3%) and 3 (4.2%). The proportion of identified serotypes contained in the heptavalent, 10-valent and 13-valent conjugate vaccines was 53.1, 86.5, and 96.9%, respectively. Pneumococcal strains were sensitive to penicillin (minimum inhibitory concentration, MIC ≤ 2 µg/mL) in 100 cases (93.5%) and displayed intermediate resistance (MIC = 4 µg/mL) in 7 cases (6.5%). No strains were penicillin-resistant (MIC ≥ 8 µg/mL) according to the Clinical and Laboratory Standards Institute 2008 standards. Tested isolates were highly sensitive to vancomycin, rifampicin, ceftriaxone, clindamycin, erythromycin, and chloramphenicol. Our results confirm a significant potential impact of conjugate vaccines, mainly 10-valent and 13-valent, on invasive pneumonia. Furthermore, susceptibility testing results show that penicillin is still the treatment of choice for invasive pneumonia in our setting.

  13. Bacterial Pneumonia in Elderly Japanese Populations

    Directory of Open Access Journals (Sweden)

    Naoya Miyashita

    2018-01-01

    Full Text Available Bacterial pneumonia is one of the most important infectious diseases in terms of incidence, effect on quality of life, mortality, and impact on society. Pneumonia was the third leading cause of death in Japan in 2011. In 2016, 119 650 Japanese people died of pneumonia, 96% of whom were aged 65 years and above. The symptoms of pneumonia in elderly people are often atypical. Aspiration pneumonia is seen more frequently than in young people because of swallowing dysfunction in the elderly. The mortality rate is also higher in the elderly than in young people. In Japan, the population is aging at an unprecedented rate, and pneumonia in the elderly will be increasingly important in medicine and medical economics in the future. To manage pneumonia in the elderly, it is important to accurately evaluate its severity, administer appropriate antibiotic treatment, and implement effective preventive measures.

    Although thousands of infants under the age of 12 months die each year from pneumonia in Latin America, little is known regarding the true occurrence of pneumonia, wheezing and other related respiratory illnesses in this age group. In order to describe the prevalence and risk factors for radiologically confirmed pneumonia during the first year of life, a birth-cohort (n = 188) of infants born in a low-income area in Santiago, Chile was followed up monthly. The prevalence of pneumonia during the first year of life was 13.3 % and there were no fatal events. Exclusive breastfeeding during the first 4 months of life was more prevalent in the non pneumonia group; conversely, wheezing episodes during 0-3 and 3-6 months of age, and hospitalization due to lower respiratory infection during 3-6 and 9-12 months of age were more prevalent in the pneumonia group. After a logistic multivariate analysis, the only risk factor that remained related with pneumonia was wheezing during the first 3 months of life (adjusted OR: 7.7, 95 CI: 1.32-44.92, p = 0.024); while breastfeeding during the first 4 months was an independent protective factor for pneumonia (adjusted OR: 0.11, 95 CI: 0.03-0.44, p = 0.002). The significant protective effect of exclusive breast feeding against pneumonia in this cohort and the evident role of recurrent wheezing as risk factor for pneumonia during the first year of life support the implementation or reinforcement of public policies encouraging exclusive breastfeeding and an adequate management of wheezing since the first months of life.

    This prospective study was performed to evaluate serotype distribution, multilocus sequence typing, and antibiotic susceptibility of Streptococcus pneumoniae identified in Korean children with acute otitis media (AOM) after the introduction of a 7-valent pneumococcal conjugate vaccine (PCV7). Nasopharyngeal aspirates were collected from children diagnosed with AOM in seven hospitals in Korea. The bacteria identified in these samples and the serotypes, sequence types (STs), and antibiotic susceptibilities of S. pneumoniae isolates were evaluated. A total of 390 children were enrolled, and bacteria were identified in 376 (96.4%) children. S. pneumoniae, Haemophilus influenzae and Moraxella catarrhalis were identified in 155 (39.7%), 127 (32.6%) and 86 (22.1%) children, respectively. Serotype 19A (22.4%) was the most common S. pneumoniae serotype, with serogroups 11 (14.7%) and 15 (13.5%) following. ST320 (23.5%) was the most common ST; ST166 (17.0%) and ST83 (8.5%) followed. The overall susceptibility rates of S. pneumoniae to oral penicillin V and amoxicillin/clavulanate were 2.6% and 53.2%, respectively. The susceptibility rate to cefditoren was 91.0%; however, the rates for other cephalosporins were less than 10.0%. Compared with other serogroups, S. pneumoniae serogroups 19, 11, and 15 showed significantly lower susceptibility rates to all the antibiotics tested. S. pneumoniae serotype 19A, serogroups 11 and 15 were the major nasopharyngeal-colonizing bacteria in Korean children with AOM after the introduction of PCV7. These relatively prevalent serotype/serogroups showed lower antibiotic susceptibility rates. Copyright © 2016. Published by Elsevier Ltd.

  19. A formula for continued improvement: Audit follow-up

    In his book Management Audits, Allan J. Sayle states, ''QA standards stipulate that corrective action, required as a result of performing an audit, be followed up and closed out. There would, indeed, be little point in performing audits, requiring corrective action, or having a QA system at all if the auditee knows that the auditor will never verify that the corrective action has been efficaciously implemented.'' The QA auditor has an obligation to include follow-up in the overall audit planning. All too often the auditor will go to great lengths to plan and perform an audit only to have a recurring finding in the next audit. The proposed corrective action was only promissory and was not designed to stop the problem from recurring or to identify its root cause. Auditors do a disservice to the overall QA program and particularly to the customer when they fail to follow up and verify that an audit corrective action has been effectively implemented. In this paper, the techniques used by the quality assurance auditors at the Pacific Northwest Laboratory (PNL) will be presented. Although PNL is a research and development laboratory, the techniques outlined in this paper could be applied to any industry conducting quality assurance audits. Most important, they provide a formula for continued improvement by assuring that audit follow-up is timely, meaningful, and permanent

    Chlamydia pneumoniae and Mycoplasma pneumoniae were evaluated as agents of persistent cough in adolescents and adults (n = 491). Tests of 473 respiratory specimens by culture or PCR or both identified four episodes (0.8%) of M. pneumoniae-associated illness and no episodes of C. pneumoniae illness, suggesting that these bacteria do not frequently cause persistent cough.

    The most common pediatric burn injury is a superficial scald. The current follow-up protocol for such burns includes review of the patient at 2 weeks postinjury and then 2 months later. The authors decided to review the protocol to assess the need for this second follow-up. A retrospective study reviewed the case notes of patients younger than 16 years at the time of their injury presenting with a scald over 5% TBSA. The progress of healing and scar development up to 5 years follow-up was assessed. This study showed that scalds healing within 2 weeks following injury rarely became hypertrophic. A prospective study was performed over a 10-month period. All children who suffered a superficial partial-thickness scald injury were included. At the 2-week appointment, the need for further follow-up was predicted. The accuracy of this prediction was assessed 2 months later. This study showed that an experienced member of the burns team could reliably predict at 2-week appointment those children who could be safely discharged with no subsequent need for scar management. This study suggests that it will be safe to modify the follow-up protocol, reducing the number of clinic attendances.

    Objective: To observed the long-term follow-up of the two types of interventional procedure for achalasia. Methods: The study cohort was comprised of 140 patients of achalasia including 70 patients treated under fluoroscopy with pneumatic dilation (group A) and 70 with temporary partially covered metal stent dilation (group B). Results: One hundred and forty dilations were performed on the 70 patients of group A with complications of chest pain (n=35), reflux (n=18), and bleeding (n=8); 38 patients of relapsing dysphagia during a 12-month follow-up, and 50 patients out of 60 of recurrent dysphagia during a 36-month follow-up. Seventy partially covered expandable metal stents were temporarily placed in the 70 patients of group B and withdrawn after 3-7 days via gastroscopy with complications of chest pain (n=28), reflux (n=15), and bleeding (n=9); 7 patients out of 70 exhibited dysphagia relapse during a 12-month followup, and 9 out of 58 patients exhibited dysphagia relapse during a 36-month follow-up. All the stents were inserted and withdrawn successfully. The follow-up in groups A-B lasted for 12-96 months. Conclusion: Temporary partially covered metal stent dilation is one of the best methods of interventional procedure for achalasia in long-term follow-up. (authors)

    Full Text Available Pneumonia and diarrhoea have been the leading causes of global child mortality for many decades. The work of Child Health Epidemiology Reference Group (CHERG has been pivotal in raising awareness that the UN's Millennium Development Goal 4 cannot be achieved without increased focus on preventing and treating the two diseases in low– and middle–income countries. Global Action Plan for Pneumonia (GAPP and Diarrhoea Global Action Plan (DGAP groups recently concluded that addressing childhood pneumonia and diarrhoea is not only the leading priority but also the greatest opportunity in global health today: scaling up of existing highly cost–effective interventions could prevent 95% of diarrhoea deaths and 67% of pneumonia deaths in children younger than 5 years by the year 2025. The cost of such effort was estimated at about US$ 6.7 billion.

    Background and objective: The management of community-acquired pneumonia (CAP) depends, in part, on the identification of the causative agents. The objective of this study was to determine the potential of thin-section computed tomography (CT) in differentiating bacterial and non-bacterial pneumonia. Patients and methods: Thin-section CT studies were prospectively examined in hospitalized CAP patients within 2 days of admission, followed by retrospective assessment by two pulmonary radiologists. Thin-section CT findings on the pneumonias caused by each pathogen were examined, and two types of pneumonias were compared. Using multivariate logistic regression analyses, receiver operating characteristic (ROC) curves were produced. Results: Among 183 CAP episodes (181 patients, 125 men and 56 women, mean age {+-} S.D.: 61.1 {+-} 19.7) examined by thin-section CT, the etiologies of 125 were confirmed (94 bacterial pneumonia and 31 non-bacterial pneumonia). Centrilobular nodules were specific for non-bacterial pneumonia and airspace nodules were specific for bacterial pneumonia (specificities of 89% and 94%, respectively) when located in the outer lung areas. When centrilobular nodules were the principal finding, they were specific but lacked sensitivity for non-bacterial pneumonia (specificity 98% and sensitivity 23%). To distinguish the two types of pneumonias, centrilobular nodules, airspace nodules and lobular shadows were found to be important by multivariate analyses. ROC curve analysis discriminated bacterial pneumonia from non-bacterial pneumonia among patients without underlying lung diseases, yielding an optimal point with sensitivity and specificity of 86% and 79%, respectively, but was less effective when all patients were analyzed together (70% and 84%, respectively). Conclusion: Thin-section CT examination was applied for the differentiation of bacterial and non-bacterial pneumonias. Though showing some potential, this examination at the present time would

    To determine the variability of crackle pitch and crackle rate during a single automated-auscultation session with a computerized 16-channel lung-sound analyzer. Forty-nine patients with pneumonia, 52 with congestive heart failure (CHF), and 18 with interstitial pulmonary fibrosis (IPF) performed breathing maneuvers in the following sequence: normal breathing, deep breathing, cough several times; deep breathing, vital-capacity maneuver, and deep breathing. From the auscultation recordings we measured the crackle pitch and crackle rate. Crackle pitch variability, expressed as a percentage of the average crackle pitch, was small in all patients and in all maneuvers: pneumonia 11%, CHF 11%, pulmonary fibrosis 7%. Crackle rate variability was also small: pneumonia 31%, CHF 32%, IPF 24%. Compared to the first deep-breathing maneuver (100%), the average crackle pitch did not significantly change following coughing (pneumonia 100%, CHF 103%, IPF 100%), the vital-capacity maneuver (pneumonia 100%, CHF 92%, IPF 104%), or during quiet breathing (pneumonia 97%, CHF 100%, IPF 104%). Similarly, the average crackle rate did not change significantly following coughing (pneumonia 105%, CHF 110%, IPF 90%) or the vital-capacity maneuver (pneumonia 102%, CHF 101%, IPF 99%). However, during normal breathing the crackle rate was significantly lower in the patients with pneumonia (74%, P auscultation session suggests that crackle rate can be used to follow the course of cardiopulmonary illnesses such as pneumonia, IPF, and CHF.

    Graves' ophthalmopathy may first appear or worsen during or after treatment for hyperthyroidism. We followed up 158 Graves' hyperthyroid patients treated with radioiodine of which 49 had Grave's' ophthalmopathy during presentation in Nuclear Medicine Centre, Khulna during the period from 1995 to 2000. The aim of our study is to see the effect of radioiodine in Graves' ophthalmopathy. All the patients received radioiodine at fixed dose regime ranged from 7 mCi to 12 mCi. The duration of follow up was at least 12 months Graves' ophthalmopathy patients, 4 (4/49 i.e., 8.2%) showed exaggeration of ophthalmopathy and the rest (45/49 i.e., 91.8%) remained unchanged. None of ophthalmopathy developed among any of Graves' hyperthyroid or disappeared after radioiodine treatment during follow up period. From the study we concluded that eye changes in Graves' hyperthyroidism remain unchanged or exaggerated after radioiodine therapy and needs ophthalmologist care.(author)

    Full Text Available Josef Yayan Department of Internal Medicine, Division of Pulmonary, Allergy and Sleep Medicine, Saarland University Medical Center, Homburg/Saar, Germany Background: Community-acquired pneumonia (CAP is an acute inflammation of the lungs, which is often caused by Streptococcus pneumoniae. CAP is the leading cause of death by infectious disease in industrialized countries. Therefore, an immediate and effective antibiotic therapy is of great importance for the nonfatal outcome of the disease. The literature contains increasing data about the development of resistance to antibiotics that are used for the treatment of CAP caused by S. pneumoniae; this article also examines the possible development of resistance to antibiotics in S. pneumoniae in recent years.Methods: Within the study period of 2004–2014, all hospital charts from patients with CAP caused by S. pneumoniae were collected from the Department of Internal Medicine, Saarland University Medical Center, Homburg/Saar, Germany. The tracheal secretions of S. pneumoniae in CAP patients were obtained by bronchoalveolar lavage; bronchial aspirates were obtained through flexible bronchoscopy and directly from sputum, and blood cultures were examined microbiologically for microorganisms.Results: From a total of 100 patients with CAP caused by S. pneumoniae, 23 (53.49% [34.78% female], 95% confidence interval, 38.58–68.4 patients with a mean age of 59.78±15.77 years met the inclusion criteria of this investigation. These patients were compared to a total of 20 (46.51% [35% female], 95% confidence interval, 31.6–61.42 patients with a mean age of 58.9±13.36 years with CAP who were infested with S. pneumoniae. In the latter group, the streptococcal antigen was detected in pulmonary aspirations by bronchoscopy or in urine using polymerase chain reaction and a rapid pneumococcal test. Penicillin G and vancomycin had a high rate of sensitivity on the antibiogram for S. pneumoniae, which was

    Full Text Available Background: stroke-associated pneumonia prolongs hospital stay and is an important risk factor for morbidity and mortality. Objective: to determine risk factors for stroke-associated pneumonia. Methods: a prospective single-cohort study was conducted involving 390 patients aged 16-93 years who met clinical and neuroimaging criteria for acute stroke treated at the Carlos Manuel de Céspedes Hospital from January 2012 through March 2015. Univariate comparison of qualitative variables was performed by using the Kaplan-Meier method. The Cox regression model was applied for multivariate analysis of risk factors for pneumonia. The area under the ROC curve was used to determine the discriminatory power of the model. Results: two hundred thirteen patients (54.6 % with ischemic stroke and 177 (45.4 % with hemorrhagic stroke were studied. Cases of nosocomial pneumonia after acute stroke accounted for 25.4 %. Subjects who developed pneumonia had lower scores on the Glasgow scale and higher scores on the modified Rankin scale. The following risk factors were identified using the Cox regression model: Glasgow coma score (Exp (B: 0.687; 95 % CI 0.630 to 0.750 and stroke subtype (Exp (B: 1.723; 95 % CI 1.137 to 2.610. The area under the ROC curve was 0.88. Conclusions: the risk factors for the development of nosocomial pneumonia after acute stroke found were the level of consciousness and suffering a hemorrhagic stroke. Other influencing variables are chronic obstructive pulmonary disease and heart disease as a comorbid condition.

    Rationale: Relationships between chronic health conditions and acute infections remain poorly understood. Preclinical studies suggest crosstalk between nervous and immune systems. Objectives: To determine bidirectional relationships between cognition and pneumonia. Methods: We conducted longitudinal analyses of a population-based cohort over 10 years. We determined whether changes in cognition increase risk of pneumonia hospitalization by trajectory analyses and joint modeling. We then determined whether pneumonia hospitalization increased risk of subsequent dementia using a Cox model with pneumonia as a time-varying covariate. Measurements and Main Results: Of the 5,888 participants, 639 (10.9%) were hospitalized with pneumonia at least once. Most participants had normal cognition before pneumonia. Three cognition trajectories were identified: no, minimal, and severe rapid decline. A greater proportion of participants hospitalized with pneumonia were on trajectories of minimal or severe decline before occurrence of pneumonia compared with those never hospitalized with pneumonia (proportion with no, minimal, and severe decline were 67.1%, 22.8%, and 10.0% vs. 76.0%, 19.3%, and 4.6% for participants with and without pneumonia, respectively; P pneumonia, even in those with normal cognition and physical function before pneumonia (β = −0.02; P pneumonia were subsequently at an increased risk of dementia (hazard ratio, 2.24 [95% confidence interval, 1.62–3.11]; P = 0.01). Associations were independent of demographics, health behaviors, other chronic conditions, and physical function. Bidirectional relationship did not vary based on severity of disease, and similar associations were noted for those with severe sepsis and other infections. Conclusions: A bidirectional relationship exists between pneumonia and cognition and may explain how a single episode of infection in well-appearing older individuals accelerates decline in chronic health conditions and loss of

    The value of CT in the diagnosis of tuberculous meningitis (TBM) in children is well reported. Follow-up CT scanning for these patients is, however, not well described and, in particular, the value of early follow-up CT has not been addressed for children with TBM. To assess the value of early follow-up CT in children with TBM in identifying diagnostic, prognostic and therapeutically relevant features of TBM. A retrospective 4-year review of CT scans performed within 1 week and 1 month of initial CT in children with proven (CSF culture-positive) and probable TBM (CSF profile-positive but culture-negative) and comparison with initial CT for the diagnostic, prognostic and therapeutic CT features of TBM. The CT scans of 50 children were included (19 ''definite'' TBM; 31 ''probable'' TBM). Of these, 30 had CT scans performed within 1 week of the initial CT. On initial CT, 44 patients had basal enhancement. Only 24 patients had contrast medium-enhanced follow-up scans. Important findings include: 8 of 29 patients (who were not shunted) developed new hydrocephalus. New infarcts developed in 24 patients; 45% of those who did not have infarction initially developed new infarcts. Three of the six patients who did not show basal enhancement on initial scans developed this on the follow-up scans, while in seven patients with pre-existing basal enhancement this became more pronounced. Two patients developed hyperdensity in the cisterns on non-contrast medium scans. Eight patients developed a diagnostic triad of features. Three patients developed CT features of TBM where there was none on the initial scans. Early follow-up CT is useful in making a diagnosis of TBM by demonstrating features that were not present initially and by demonstrating more sensitive, obvious or additional features of TBM. In addition, follow-up CT is valuable as a prognostic indicator as it demonstrates additional infarcts which may have developed or become more visible since the initial study. Lastly

    In this paper we report our recent experience indicating usefulness of 67 Ga-citrate scintigraphy in 4 cases with inflammatory pulmonary diseases. These cases showed abnormal pulmonary 67 Ga uptake with normal chest radiographs. The first case with malignant lymphoma and the second one with lung cancer suffered from pulmonary infection following secondary immuno-insufficiency due to radiotherapy and chemotherapy. Pneumocystis carinii was suspected as causative agent in the first case, and gram negative bacilli in the second case. The third case with lung cancer developed radiation pneumonia after radiotherapy. The fourth case with acute bronchitis developed drug induced interstitial pneumonia presumably due to minocycline administration. It is concluded that 67 Ga-citrate scintigraphy is more sensitive for early detection of interstitial pneumonia than routine chest radiography. (author)

    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.

    Androgens have been shown to influence both the immune system and lung tissue, raising the hypothesis that androgen deprivation therapy (ADT) for prostate cancer may increase the risk of pneumonia. Thus, the aim of this study was to determine whether ADT is associated with an increased risk of hospitalisation for community-acquired pneumonia in patients with prostate cancer. This was a population-based cohort study using the United Kingdom Clinical Practice Research Datalink linked to the Hospital Episode Statistics repository. The cohort consisted of 20 310 men newly diagnosed with non-metastatic prostate cancer between 1 April 1998 and 31 March 2015. Time-dependent Cox proportional hazards models were used to estimate adjusted HRs and 95% CIs for hospitalisation for community-acquired pneumonia associated with current and past use of ADT compared with non-use. During a mean follow-up of 4.3 years, there were 621 incident hospitalisations for community-acquired pneumonia (incidence rate: 7.2/1000 person-years). Current ADT use was associated with an 81% increased risk of hospitalisation for community-acquired pneumonia (12.1 vs 3.8 per 1000 person-years, respectively; HR 1.81, 95% CI 1.47 to 2.23). The association was observed within the first six months of use (HR 1.73, 95% CI 1.23 to 2.42) and remained elevated with increasing durations of use (≥25 months; HR 1.79, 95% CI 1.39 to 2.30). In contrast, past ADT use was not associated with an increased risk (HR 1.23, 95% CI 0.95 to 1.60). The use of ADT is associated with an increased risk of hospitalisation for community-acquired pneumonia in men with prostate cancer. Published by the BMJ Publishing Group Limited.

    The authors report a case of lipoid pneumonia in an 80 year old man with chronic constipation in regular use of mineral oil as a laxative. According to his family, he experienced coughing episodes when he took his medication. He also presented dyspnoea at rest and diminished consciousness levels. Chest radiographs showed a consolidation area in the posterior segment of right upper lobe, which did not change on successive exams. High resolution computed tomography demonstrated low-density consolidation with negative Hounsfield units (-29 to -83 UH) and ground-glass opacities in the right upper lobe and inferior lobes. These opacities predominated in the posterior regions of the lungs. The diagnosis was confirmed by the presence of oil material on bronchoalveolar washing. The patient was advised to discontinue the ingestion of mineral oil and did not return for follow-up. (author)

    Possibility of therapeutic application of UV irradiation (UVI) of blood and the mechanism of its medical effect has been studied in 111 patients with intoxication by psychotropic drugs and organic phosphorus insecticides with poisonings by cautering substances and by alcohol in patients with pneumonia. UVI has been carried out by means of MD-73M ''Izol'da'' device with the DRB-8 mercury lamp. The procedure permits to reduce lethality and cases of pneumonia development more than two times as well as to decrease periods of treatment. To achieve the best effect, the radiation energy should be not less than 100 J and not more than 15 J. Early application (in 1-2 days before poisoning or pneumonia development) of UVI in 100-150 J dose per a period of treatment is most effective. It is established that the mechanism of medical UVI effect in blood is mainly related to stimulation of a cell unit of immunity as well as to improvement of rheologic properties of blood and a qualitative composition of erythrocytes, that favours the strengthening of redox and desintoxication processes in an organism

    The purpose was to describe aspiration pneumonia in the context of other lung infections and aspiration syndromes and to distinguish between the main scenarios commonly implied when the terms aspiration or aspiration pneumonia are used. Finally, we aim to summarize current evidence surrounding the diagnosis, microbiology, treatment, risks, and prevention of aspiration pneumonia. Medline was searched from inception to November 2013. All descriptive or experimental studies that added to the understanding of aspiration pneumonia were reviewed. All studies that provided insight into the clinical aspiration syndromes, historical context, diagnosis, microbiology, risk factors, prevention, and treatment were summarized within the text. Despite the original teaching, aspiration pneumonia is difficult to distinguish from other pneumonia syndromes. The microbiology of pneumonia after a macroaspiration has changed over the last 60 years from an anaerobic infection to one of aerobic and nosocomial bacteria. Successful antibiotic therapy has been achieved with several antibiotics. Various risks for aspiration have been described leading to several proposed preventative measures. Aspiration pneumonia is a disease with a distinct pathophysiology. In the modern era, aspiration pneumonia is rarely solely an anaerobic infection. Antibiotic treatment is largely dependent on the clinical scenario. Several measures may help prevent aspiration pneumonia. Copyright © 2014 Elsevier Inc. All rights reserved.

    Despite recommendations, only a proportion of long-term childhood cancer survivors attend follow-up care. We aimed to (1) describe the follow-up attendance of young survivors aged 11-17 years; (2) describe the parental involvement in follow-up, and (3) investigate predictors of follow-up attendance and parental involvement. As part of the Swiss Childhood Cancer Survivor Study, a follow-up questionnaire was sent to parents of childhood cancer survivors aged 11-17 years. We assessed follow-up attendance of the child, parents' involvement in follow-up, illness perception (Brief IPQ), and sociodemographic data. Clinical data was available from the Swiss Childhood Cancer Registry. Of 309 eligible parents, 189 responded (67 %; mean time since diagnosis 11.3 years, range 6.8-17.2) and 75 % (n = 141) reported that their child still attended follow-up. Of these, 83 % (n = 117) reported ≥1 visit per year and 17 % (n = 23) reported parents (92 %) reported being involved in follow-up (n = 130). In multivariable and Cox regression analyses, longer time since diagnosis (p = 0.025) and lower perceived treatment control (assessed by IPQ4: how much parents thought follow-up can help with late effects; p = 0.009) were associated with non-attendance. Parents' overall information needs was significantly associated with parental involvement in the multivariable model (p = 0.041). Educating survivors and their parents on the importance and effectiveness of follow-up care might increase attendance in the longer term.

    Full Text Available Background : The principal aim of the present study was to determine whether Acinetobacter spp. pneumonia differs from hospital-acquired pneumonias (HAPs caused by other agents with respect to therapeutic success and survival rate. METHODS : This study includes 140 adult patients diagnosed with HAPs caused by identified etiologic agents between March 2005 and February 2006. These patients were divided into two groups according to the agent responsible for their infection (Acinetobacter spp. [n = 63] or non-Acinetobacter spp. [n = 77]. The groups were compared in terms of risk factors, therapeutic success and six-week survival rates. Results : Previous antibiotic use and the risk of aspiration were independent factors responsible for the development of Acinetobacter spp. pneumonia. Hypoalbuminemia, steroid use and the use of a mechanical ventilator were determined to be mortality-associated independent risk factors for Acinetobacter spp. pneumonia. The clinical success rate at the end of therapy was 41.6% and, at the sixth week, the survival rate was 35% among patients in whom Acinetobacter spp. was the causative agent. Conversely, in the control group, these values were 43 and 32%, respectively ( P > 0.05. We found that the use of the appropriate antibiotics for the treatment of Acinetobacter spp. pneumonia was an important factor in survival ( P < 0.001. Conclusion : The outcomes of Acinetobacter spp. pneumonia do not differ from HAPs associated with non-Acinetobacter spp. in terms of therapeutic success and survival rates.

    The foregoing experiments show that in cats a definite lobar pneumonia may be caused by Bacillus mucosus capsulatus. Judging both from the clinical course and from the pathological findings, this form of pulmonary infection differs from the usual pneumococcus types of pneumonia and closely resembles the so called Friedländer's bacillus or Bacillus pneumonioe in man. In all instances in which a lobar pneumonia was found after the injection of the bacillus, a similar organism was recovered from the lung, and in no case was this associated with other organisms. The course of the disease in cats is very short, the animals developing early symptoms of profound toxemia. In 87 per cent of the animals showing a lobar pneumonia positive blood cultures were obtained. The pathological findings, judging from the early stages of the disease, are subject to considerable variation. In some instances the process may suggest a pseudolobar or confluent lobular distribution. In these cases the lung has a mottled, marble-like appearance. In the majority of cases, however, the process gave a more homogeneous appearance, suggesting a diffuse and uniform distribution. Foci of hemorrhage were not uncommon in both. Such areas cause the mottled appearance sometimes found. In all instances the consolidated lung presents a greater infiltration of tissue than is usually seen in other types of experimental pneumonia. Although the exudate as seen on the cut surface may be abundant and especially viscid in character, this is not present in most cases. The cut surface of the consolidated lung does not present a granular appearance. The histological findings are also subject to considerable variation. In most instances the infundibular and alveolar spaces are completely filled with an exudate made up chiefly of polymorphonuclear cells. Associated with these are the capsulated bacilli, large vacuolated mononuclear phagocytic cells, and red blood cells, and occasionally small amounts of fibrin. The

    2016-12-01

    Predictive or prognostic analysis plays an increasingly important role in the era of personalized medicine to identify subsets of patients whom the treatment may benefit the most. Although various time-dependent covariate models are available, such models require that covariates be followed in the whole follow-up period. This article studies a new class of functional survival models where the covariates are only monitored in a time interval that is shorter than the whole follow-up period. This paper is motivated by the analysis of a longitudinal study on advanced myeloma patients who received stem cell transplants and T cell infusions after the transplants. The absolute lymphocyte cell counts were collected serially during hospitalization. Those patients are still followed up if they are alive after hospitalization, while their absolute lymphocyte cell counts cannot be measured after that. Another complication is that absolute lymphocyte cell counts are sparsely and irregularly measured. The conventional method using Cox model with time-varying covariates is not applicable because of the different lengths of observation periods. Analysis based on each single observation obviously underutilizes available information and, more seriously, may yield misleading results. This so-called partial follow-up study design represents increasingly common predictive modeling problem where we have serial multiple biomarkers up to a certain time point, which is shorter than the total length of follow-up. We therefore propose a solution to the partial follow-up design. The new method combines functional principal components analysis and survival analysis with selection of those functional covariates. It also has the advantage of handling sparse and irregularly measured longitudinal observations of covariates and measurement errors. Our analysis based on functional principal components reveals that it is the patterns of the trajectories of absolute lymphocyte cell counts, instead of

    The strain on clinic and surgeon resources resulting from a rise in demand for total knee replacement (TKR) requires reconsideration of when and how often patients need to be seen for follow-up. Surgeons will otherwise require increased paramedical staff or need to limit the number of TKRs they undertake. We reviewed the outcome data of 16 414 primary TKRs undertaken at our centre to determine the time to re-operation for any reason and for specific failure mechanisms. Peak risk years for failure were determined by comparing the conditional probability of failure, the number of failures divided by the total number of TKRs cases, for each year. The median times to failure for the most common failure mechanisms were 4.9 years (interquartile range (IQR) 1.7 to 10.7) for femoral and tibial loosening, 1.9 years (IQR 0.8 to 3.9) for infection, 3.1 years (IQR 1.6 to 5.5) for tibial collapse and 5.6 years (IQR 3.4 to 9.3) for instability. The median time to failure for all revisions was 3.3 years (IQR 1.2 to 8.5), with an overall revision rate of 1.7% (n = 282). Results from our patient population suggest that patients be seen for follow-up at six months, one year, three years, eight years, 12 years, and every five years thereafter. Patients with higher pain in the early post-operative period or high body mass index (≥ 41 kg/m(2)) should be monitored more closely.

    Predict the number of hospitalizations for asthma and pneumonia associated with exposure to air pollutants in the city of São José dos Campos, São Paulo State. This is a computational model using fuzzy logic based on Mamdani's inference method. For the fuzzification of the input variables of particulate matter, ozone, sulfur dioxide and apparent temperature, we considered two relevancy functions for each variable with the linguistic approach: good and bad. For the output variable number of hospitalizations for asthma and pneumonia, we considered five relevancy functions: very low, low, medium, high and very high. DATASUS was our source for the number of hospitalizations in the year 2007 and the result provided by the model was correlated with the actual data of hospitalization with lag from zero to two days. The accuracy of the model was estimated by the ROC curve for each pollutant and in those lags. In the year of 2007, 1,710 hospitalizations by pneumonia and asthma were recorded in São José dos Campos, State of São Paulo, with a daily average of 4.9 hospitalizations (SD = 2.9). The model output data showed positive and significant correlation (r = 0.38) with the actual data; the accuracies evaluated for the model were higher for sulfur dioxide in lag 0 and 2 and for particulate matter in lag 1. Fuzzy modeling proved accurate for the pollutant exposure effects and hospitalization for pneumonia and asthma approach.

    In a two-center follow-up study on the early-onset form of anorexia nervosa, we reexamined 43 (74%) of 58 former patients who had developed anorexia nervosa at the age of 13 years or younger. In addition to make a standardized assessment of the eating disorder at follow-up we assessed psychiatric comorbidity with a structured interview based on the criteria of DSM-III-R and ICD-10. After an average follow-up period of 6.8 years, 8 (18%) of our former patients had an eating disorder not otherwise specified (EDNOS) and 4 (9%) still suffered from anorexia nervosa. 5 (11%) of the subjects had developed bulimia nervosa. In 3 cases (7%) we found both syndromes. 12 (28%) of our former patients had an additional psychiatric disorder. The results of our study indicate that the quality of outcome in patients with an early-onset form of anorexia nervosa does not differ from that in individuals with a later manifestation of the eating disorder. Factors of prognostic relevance were the existence of an eating disorder during the first year of life and the duration of the follow-up period.

    To assess the long-term effectiveness and safety of refractive surgery with LASIK or photorefractive keratectomy (PRK) for treating accommodative esotropia in adults. All patients with accommodative esotropia treated with LASIK or PRK until December 2007 and with a minimum follow-up of 5 years were retrospectively included. LASIK was performed on 44 eyes of 22 patients (12 women, 10 men; mean age: 22.7 ± 2.9 years). Mean postoperative follow-up was 62.1 ± 3.2 months. PRK was performed on 16 eyes of 8 patients (4 women, 4 men; mean age: 23.7 ± 1.7 years). Mean postoperative follow-up was 61.3 ± 2.8 months. At the 5-year follow-up, the mean cycloplegic refraction was more hyperopic in the PRK group (0.3 ± 0.8 vs 0.06 ± 0.3 diopters, P = .01). Correction of esotropia to esophoria or orthotropia was present in 21 patients (95.4%) treated with LASIK and in all patients treated with PRK. Both LASIK and PRK were effective in the long-term reduction of accommodative esotropia. Copyright 2014, SLACK Incorporated.

    The objectives were to conduct a 1-year follow-up of daily caffeine-using adolescents to further describe caffeine dependence symptoms and to determine whether caffeine dependence is associated with other substance dependence disorders. Twenty-one of 36 (58.3%) adolescents who participated in a study of caffeine dependence returned for follow-up. The previous study was a case series of adolescents who consumed caffeine daily and met some Diagnostic and Statistical Manual of Mental Disorders (fourth edition) substance dependence criteria as applied to caffeine. At follow-up, caffeine consumption from beverages was 179.9 +/- 151.8 mg/day. Of the 21 teenagers, 23.8% (n = 5) met criteria for caffeine dependence. Four of these participants developed caffeine dependence during the follow-up period. Other substance dependence disorders were not overrepresented in the caffeine dependent group compared to the caffeine nondependent group. The most commonly reported withdrawal symptoms in dependent teenagers (at baseline and follow-up combined) were feeling drowsy/tired, fatigued, or sluggish/slowed down (83.3% each) and headache (75.0%). Caffeine dependence occurs in some adolescents who drink caffeine daily and is marked by symptoms similar to those found in adults.

    Programmes for early childhood childhood hearing impairment identification allows to quickly start the appropriate hearing aid fitting and rehabilitation process; nevertheless, a large number of patients do not join the treatment program. The goal of this article is to present the results of a strategic review of the strengths, weaknesses, opportunities and threats connected with the audiologic/prosthetic/language follow-up process of children with bilateral permanent hearing impairment. Involving small children, the follow-up includes the involvement of specialised professionals of a multidisciplinary team and a complex and prolonged multi-faced management. Within the framework of the Italian Ministry of Health project CCM 2013 "Preventing Communication Disorders: a Regional Program for Early Identification, Intervention and Care of Hearing Impaired Children", the purpose of this analysis was to propose recommendations that can harmonise criteria for outcome evaluation and provide guidance on the most appropriate assessment methods to be used in the follow-up course of children with permanent hearing impairment. © Copyright by Società Italiana di Otorinolaringologia e Chirurgia Cervico-Facciale.

    We have three telescopes at BYU that we use to follow-up possible transiting planet canidates for the KELT team. These telescopes were used to collect data on Kelt-16b and Kelt-9b, which is the hottest known exoplanet. More recently we used the newest of these telescopes, a robotic 8-inch telescope on the roof of our building, to confirm the most recent Kelt planet that will be published soon. This research has been ideal for the teaching and training of undergraduate students in the art of photometric observing and data reduction. In this presentation I will highlight how we are using our membership in the Kelt team to further the educational objective of our undergraduate astronomy program, while contributing meaningful science to the ever growing field of exoplanet discovery. I will also highlight a few of the more interesting Kelt planets and the minimum telescope requirements for detecting these planets. I will then discuss the sensitivities required to follow-up future TESS candidates, which may be of interest to others interested in joining the TESS follow-up teams.

    Repetition of the onset of aspiration pneumonia in aged patients is common and causes chronic inflammation. The inflammation induces proinflammatory cytokine production and atrophy in the muscles. The proinflammatory cytokines induce muscle proteolysis by activating calpains and caspase-3, followed by further degradation by the ubiquitin-proteasome system. Autophagy is another pathway of muscle atrophy. However, little is known about the relationship between aspiration pneumonia and muscle. For swallowing muscles, it is not clear whether they produce cytokines. The main objective of this study was to determine whether aspiration pneumonia induces muscle atrophy in the respiratory (the diaphragm), skeletal (the tibialis anterior, TA), and swallowing (the tongue) systems, and their possible mechanisms. We employed a mouse aspiration pneumonia model and computed tomography (CT) scans of aged pneumonia patients. To induce aspiration pneumonia, mice were inoculated with low dose pepsin and lipopolysaccharide solution intra-nasally 5 days a week. The diaphragm, TA, and tongue were isolated, and total RNA, proteins, and frozen sections were stored. Quantitative real-time polymerase chain reaction determined the expression levels of proinflammatory cytokines, muscle E3 ubiquitin ligases, and autophagy related genes. Western blot analysis determined the activation of the muscle proteolysis pathway. Frozen sections determined the presence of muscle atrophy. CT scans were used to evaluate the muscle atrophy in aged aspiration pneumonia patients. The aspiration challenge enhanced the expression levels of proinflammatory cytokines in the diaphragm, TA, and tongue. Among muscle proteolysis pathways, the aspiration challenge activated caspase-3 in all the three muscles examined, whereas calpains were activated in the diaphragm and the TA but not in the tongue. Activation of the ubiquitin-proteasome system was detected in all the three muscles examined. The aspiration challenge

    Full Text Available Clinical isolates of carbapenem-resistant Klebsiella pneumoniae (K. pneumoniae strains are being increased worldwide. Five pan-resistant K. pneumoniae strains have been isolated from respiratory and ICU wards in a Chinese hospital, and reveal strong resistance to all β-lactams, fluoroquinolones and aminoglycosides. Totally 27 β-lactamase genes and 2 membrane pore protein (porin genes in 5 K. pneumoniae strains were screened by polymerase chain reaction (PCR. The results indicated that all of 5 K. pneumoniae strains carried blaTEM-1 and blaDHA-1 genes, as well as base deletion and mutation of OmpK35 or OmpK36 genes. Compared with carbapenem-sensitive isolates by sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE, the resistant isolates markedly lacked the protein band of 34-40 kDa, which might be the outer membrane proteins of OmpK36 according to the electrophoresis mobility. In addition, the conjugation test was confirmed that blaDHA-1 mediated by plasmids could be transferred between resistant and sensitive strains. When reserpine (30 µg/mL and carbonyl cyanide m-chlorophenylhydrazone (CCCP (50 µg/mL were added in imipenem and meropenem, the MICs had no change against K. pneumoniae strains. These results suggest that both DHA-1 β-lactamase and loss or deficiency of porin OmpK36 may be the main reason for the cefoxitin and carbapenem resistance in K. pneumoniae strains in our hospital.

    Regular use of inhaled corticosteroids (ICS) in patients with obstructive lung diseases has been associated with a higher risk of pneumonia, particularly in COPD. The risk of pneumonia has not been previously evaluated in relation to ICS particle size and dose used. Historical cohort, UK database study of 23,013 patients with obstructive lung disease aged 12-80 years prescribed extra-fine or fine-particle ICS. The endpoints assessed during the outcome year were diagnosis of pneumonia, acute exacerbations and acute respiratory events in relation to ICS dose. To determine the association between ICS particle size, dose and risk of pneumonia in unmatched and matched treatment groups, logistic and conditional logistic regression models were used. 14788 patients were stepped-up to fine-particle ICS and 8225 to extra-fine ICS. On unmatched analysis, patients stepping-up to extra-fine ICS were significantly less likely to be coded for pneumonia (adjusted odds ratio [aOR] 0.60; 95% CI 0.37, 0.97]); experience acute exacerbations (adjusted risk ratio [aRR] 0.91; 95%CI 0.85, 0.97); and acute respiratory events (aRR 0.90; 95%CI 0.86, 0.94) compared with patients stepping-up to fine-particle ICS. Patients prescribed daily ICS doses in excess of 700 mcg (fluticasone propionate equivalent) had a significantly higher risk of pneumonia (OR [95%CI] 2.38 [1.17, 4.83]) compared with patients prescribed lower doses, irrespective of particle size. These findings suggest that patients with obstructive lung disease on extra-fine particle ICS have a lower risk of pneumonia than those on fine-particle ICS, with those receiving higher ICS doses being at a greater risk.

    Besides individual care, regular follow-up studies in breast cancer patients have different aims, relative to different tumor stages at presentation. In early stages emphasis has to be laid on detection of loco-regional recurrences, which will not reduce overall survival if diagnosed and treated early. In addition, treatment effects and changes in the activity of disease are evaluated. Radiographic studies for detection of distant metastases are justified if followed by proper treatment. Early diagnosis of cancer of the opposite breast and of such cancers that are associated with breast cancer (colon, ovaries, endometrium) is imperative. The aim of a regular follow-up in more advanced tumor stages is to monitor the extent of disease and to prevent complications (e.g. fractures, spinal cord compression). In familial breast cancer first degree relatives should be included in the follow-up plan. The patient's psychosocial needs, even if not verbalized, should not be neglected. (Author)

    In 1964, the Medical Research Council undertook a trial of measles vaccine in over 36,000 United Kingdom children; 9577 of whom received live vaccine, 10,625 received inactivated followed by live vaccines, and 16,328 acted as unvaccinated controls. Participants in this study have been followed to determine the long term protection from measles vaccine and follow-up data were available on 4194, 4638 and 274 respectively. During the 5-year period 1986-90, the protective efficacy of live measles vaccine has remained high at 87%, but the 95% confidence interval was wide (-43 to 99%) due to the small numbers of cases. Between 1976 and 1990, however, the overall efficacy of the live vaccine was 92% (95% confidence interval 86 to 95%) and there was no evidence of a decline in efficacy (P = 0.13) over the 15-year period. This study suggests that the protection from live measles vaccine persists for up to 27 years after vaccination, and that no change in the current United Kingdom measles immunization policy should be made on the grounds of waning immunity.

    Little Leaguer's shoulder is a syndrome involving the proximal humeral epiphyseal plate. Conservative treatment usually resolves the symptoms. However, there are no reports of a radiographic follow-up study of this disease. The purpose of this study was to show the radiographic healing process of Little Leaguer's shoulder. A total of 19 male baseball players diagnosed as having Little Leaguer's shoulder were retrospectively evaluated. The mean age at first presentation was 12.7 years. External rotation anteroposterior radiographs of the shoulder were taken. All patients were treated with rest from throwing, and no throwing was recommended until remodeling was confirmed. Follow-up radiographs were taken at 1-month intervals to assess healing. All patients were observed until healing was confirmed radiographically, after which they returned to baseball. The mean follow-up period was 8.5 months. In addition to radiography, patients were asked whether they had any symptoms and whether they had been able to return to baseball. At the first examination, radiographs showed a wider epiphyseal plate of the throwing side compared with the asymptomatic contralateral shoulder. Healing was observed in all cases. Healing occurred first along the medial side and was then extended laterally. The mean time required for healing was 4.7 months. All patients were able to return to playing baseball at their pre-injury level of play and were asymptomatic when examined at the final follow-up. The healing process of Little Leaguer's shoulder advanced from medial to lateral, and healing was achieved about 5 months after initial examination. (orig.)

    Full Text Available Severe pneumonia remains an important cause of morbidity and mortality. Polymerase chain reaction (PCR has been shown to be more sensitive than current standard microbiological methods--particularly in patients with prior antibiotic treatment--and therefore, may improve the accuracy of microbiological diagnosis for hospitalized patients with pneumonia. Conventional detection techniques and multiplex PCR for 14 typical bacterial pneumonia-associated pathogens were performed on respiratory samples collected from adult hospitalized patients enrolled in a prospective multi-center study. Patients were enrolled from March until September 2012. A total of 739 fresh, native samples were eligible for analysis, of which 75 were sputa, 421 aspirates, and 234 bronchial lavages. 276 pathogens were detected by microbiology for which a valid PCR result was generated (positive or negative detection result by Curetis prototype system. Among these, 120 were identified by the prototype assay, 50 pathogens were not detected. Overall performance of the prototype for pathogen identification was 70.6% sensitivity (95% confidence interval (CI lower bound: 63.3%, upper bound: 76.9% and 95.2% specificity (95% CI lower bound: 94.6%, upper bound: 95.7%. Based on the study results, device cut-off settings were adjusted for future series production. The overall performance with the settings of the CE series production devices was 78.7% sensitivity (95% CI lower bound: 72.1% and 96.6% specificity (95% CI lower bound: 96.1%. Time to result was 5.2 hours (median for the prototype test and 43.5 h for standard-of-care. The Pneumonia Application provides a rapid and moderately sensitive assay for the detection of pneumonia-causing pathogens with minimal hands-on time.Deutsches Register Klinischer Studien (DRKS DRKS00005684.

    To analyze the HRCT findings of adult mycoplasma pneumonia and correlate these with clinical information. HRCT was performed in 17 cases of 15 adult patients (M:F=5:10) in whom mycoplasma pneumonia had been serologically confirmed. The pattern, extent and distribution of abnormalities were reviewed retrospectively and a changing pattern of abnormalities during the course of the disease was correlated with clinical symptoms. Unilateral(n=11) and lower lobe(n=12) involvement and multiplicity in involved lobes(n=10) were the most common abnormalities. Abnormalities on HRCT were as follows:nodules(n=15), areas of consolidation(n=14), nodules and areas of consolidation(n=13). Most abnormalities(n=11) were segmental or subsegmental in distribution. The most common nodular pattern was centrilobular micronodules(<5mm) or branching linear structures(n=15). An air-bronchogram in areas of consolidation was noted in 13 of 14 cases (92.9%). Areas of ground-glass attenuation, bronchial wall thickening and dilatation were observed in 11 cases as part of a mixed pattern. Additional findings were interlobular septal thickening(n=9), air-trapping(n=1), pleural effusion(n=2), and mediastinal lymphadenopathy(n=1). The relationship between the pattern of abnormalities and duration of the disease(from the onset of symptoms to the time of HRCT scan) was as follows. Group 1 (similar area ratio of consolidation and nodules) was predominant at 1 week, Group 2 (prominent areas of consolidation(>2/3)) at 2 weeks, and Group 3(prominent areas of nodules(>2/3)) over 3 weeks. The main findings of adult mycoplasma pneumonia were nodules or areas of consolidation with segmental or subsegmental distribution. The early stage of the disease may show a pattern of a similar prapertion of areas of consolidation and of nodules, followed by increase in the propertion of areas of consolidation(>2/3) as the disease progresses. At the resolvtion stage, the extent of lesions will decrease and nodules will be

    Full Text Available We describe the 70- month follow up of a child with idiopathic dilated cardiomyopathy and end-stage congestive heart failure (NYHA III/IV who underwent partial left ventriculectomy - the Batista operation when he was two and half years old. The clinical follow up was performed in the outpatient clinic by electrocardiography, echocardiography and radionuclide ventriculography to better analyse the left ventricular ejection fraction. The left ventricular diameter increased. Echocardiograms showed enlargement mainly in the systolic left ventricular diameter and slow decrease in fractional shortening (delta D. The child was in class I (NYHA during the follow-up. His exercise endurance was better than before surgery and hospitalization was not necessary. For these reasons, we believe that this procedure can be considered as a therapeutic option in children with severe dilated cardiomiopathy who are waiting for heart transplantation, as the shortage of donors is a fact.Relatamos a evolução durante 70 meses de uma criança submetida a ventriculectomia parcial esquerda, pela técnica de Batista aos 2 anos e 6 meses de idade, em classe funcional III/IV em decorrência de cardiomiopatia dilatada idiopática, com seguimento clínico ambulatorial. Realizamos eletrocardiogramas, ecocardiogramas seriados e ventriculografia radioisotópica para melhor analisar a fração de ejeção do ventrículo esquerdo. Houve progressivo aumento deste. O ecocardiograma mostrou aumento principalmente do diâmetro sistólico do ventrículo esquerdo com queda progressiva, porém lenta, da fração de ejeção. Apesar da progressão da disfunção miocárdica, a criança manteve-se em classe funcional I durante todo o seguimento, com melhora da tolerância ao exercício e não necessitou de internações. Por isso, achamos que o método pode ser considerado opção terapêutica em crianças com cardiomiopatia dilatada avançada, aguardando a indicação mais tardia de

    Ventilator-associated pneumonia is the most common infection in intensive care unit patients associated with high morbidity rates and elevated economic costs; Pseudomonas aeruginosa is one of the most frequent bacteria linked with this entity, with a high attributable mortality despite adequate treatment that is increased in the presence of multiresistant strains, a situation that is becoming more common in intensive care units. In this manuscript, we review the current management of ventilator-associated pneumonia due to P. aeruginosa, the most recent antipseudomonal agents, and new adjunctive therapies that are shifting the way we treat these infections. We support early initiation of broad-spectrum antipseudomonal antibiotics in present, followed by culture-guided monotherapy de-escalation when susceptibilities are available. Future management should be directed at blocking virulence; the role of alternative strategies such as new antibiotics, nebulized treatments, and vaccines is promising. PMID:26855594

    Follow-up CT scans were taken from 12 cases of craniopharyngiomas after various treatment. Preoperative CT findings of craniopharyngiomas could be classified into three types. Type 1 was a non-enhanced or a thinly ring-like enhanced large cystic mass. Type 2 was a thickly enhanced large cystic mass with small solid mass. Type 3 was a large solid mass. Postoperative follow-up CT findings were as follows: Type 1 had a favorable postoperative course because the tumor tissues of the thin cystic wall seemed to collapse only with the procedure of cystic fluid aspiration. Recurrence frequently took place in patients of Type 2 and 3 if the tumor couldn't be radically removed or radiotherapy was not given after partial resection. Radiotherapy was most effective in these cases.

    Risk of pneumonia is increased in persons with Alzheimer's disease (AD). In some studies, anticholinergic drugs (AC) have been associated with an increased pneumonia risk. We analyzed the risk of pneumonia associated with ACs in persons with AD. We performed a nested case-control study using register-based data from a Finnish nationwide MEDALZ cohort including all community-dwelling persons diagnosed with AD during 2005-2011. Cases were identified based on pneumonia diagnoses (n = 12,442) from hospital discharge and causes of death registers. Up to two controls without pneumonia were matched based on time since AD diagnoses, age, and gender for each case; AC use was measured using Anticholinergic Drug Scale. Use of AC was associated with an increased risk of pneumonia (adjusted odds ratio (OR) 1.36, 95% confidence interval (CI) 1.29-1.43). However, there was no increased pneumonia risk in persons using level 3 ACs. Incident use was associated with higher risk of pneumonia (OR 2.68, 95% CI 2.15-3.34) than prevalent use (OR 1.48, 95% CI 1.40-1.57). Among persons using cholinesterase inhibitors (AChEIs), risk of pneumonia was increased in persons using also ACs (OR 1.53, 95% CI 1.41-1.66). ACs were associated with an increased risk of pneumonia in persons with AD, especially at the time of initiation of these drugs. AC use was associated with increased pneumonia risk also in persons using AChEIs. This risk should be carefully considered when treating AD patients.

    Pineal cysts are common incidental findings in children undergoing magnetic resonance imaging (MRI). Several studies have suggested MRI follow-up if the cyst is larger than 10 mm. However, cysts do not usually change during follow-up. Prevalence, growth, and structure of the pineal cysts were analyzed to decide if follow-up MRI is necessary. A retrospective review between 2010 and 2015 was performed using 3851 MRI examinations of children aged 0-16 years to detect pineal cysts having a maximum diameter ≥ 10 mm. Eighty-one children with pineal cysts were identified and 79 of them had been controlled by MRI. Cysts were analyzed for the size, growth, and structure. A total of 1.8% of the children had a pineal cyst with a diameter ≥ 10 mm. Cysts were present in 48 girls (59.3%) and 33 boys (40.7%). Most pineal cysts (70/79) did not significantly grow during the follow-up (median 10 months, range 3-145 months). A total of 11.4% (9/79) of the cysts grew with the biggest change measured from the outer cyst wall sagittal anteroposterior dimension (mean 3.4 mm ± 1.7 mm). Only one cyst grew more than 5 mm. We found no factors correlating with the cyst growth among 9 cysts that grew > 2 mm. A majority of pineal cysts remained unchanged during the MRI follow-up. Results of this study suggest that routine MRI follow-up of pineal cysts is not necessary in the absence of unusual radiological characteristics or related clinical symptoms. (orig.)

    Environmental assessment (EA) follow-up provides a means for monitoring and evaluating the implementation of environmental impact studies. It is integral to the success or failure of a project or program. In spite of its importance, very little attention is given to the need for follow-up programs in most jurisdictions in Africa. Using a case study in the Ghanaian mining sector, this paper explores the challenges and opportunities within the country's EA process for an effective follow-up program. The paper is based on informal interviews, content analysis of relevant publications, official EA documents, and internet searches. The authors suggest a standard EA follow-up program to be formalized as an integral part of Ghana's environmental assessment policy. They also propose a follow-up process that harnesses existing opportunities within the country's EA system. This approach can be replicated in other African countries

    Full Text Available Background: Acute rhinosinusitis that usually caused by Streptococcus pneumoniae becomes the reason why patients seek for medical care. Drugs resistance in Streptococcus pneumoniae is increasing worldwide. This study was conducted to determine drugs resistance of Streptococcus pneumonia from acute rhinosinusitis in Dr. Hasan Sadikin General Hospital. Methods: A descriptive laboratory study was conducted in June–October 2014 at the Laboratory of Microbiology Faculty of Medicine Universitas Padjadjaran. The sample was taken using nasopharyngeal swabbing from 100 acute rhinosinusitis patients in Dr. Hasan Sadikin General Hospital and planted on tryptic soy agar containing 5% sheep blood and 5 μg/ml of gentamicin sulphate and then incubated in 5% CO2 incubator at 37°C for 24 hours. The identification of Streptococcus pneumonia was performed by optochin test. The susceptibility test against Streptococcus pneumoniae was done using disk diffusion method.The antibiotic disks were trimethoprim-sulfamethoxazole, oxacillin, levofloxacin, azithromycin, and doxycycline. Results: Out of 100 samples, 8 of them were tested positive for Streptococcus pneumoniae. Three of Streptococcus pneumoniae isolates died with unknown reason after it were stored at -80 .The drugs resistance test showed the resistance of Streptococcus pneumonia to oxacillin, azithromycin and trimethoprim were 6, whereas levofloxacin and doxycycline are 4. Conclusions: Streptococcus pneumonia drugs resistance in acute rhinosinusitis shows the resistance of Streptococcus pneumoniae to oxacillin, azithromycin and trimethoprim are 6, whereas the resistance to levofloxacin and doxycycline are 4.

    Most Strategic Environmental Assessment (SEA) research and applications have so far neglected the ex post stages of the process, also called SEA follow-up. Tool kits and methodological frameworks for engaging effectively with SEA follow-up have been conspicuously missing. In particular, little has so far been learned from the much more mature evaluation literature although many aspects are similar. This paper provides an analytical framework and tool kit for SEA follow-up. It is based on insights and tools developed within programme evaluation and environmental systems analysis. It is also grounded in empirical studies into real planning and programming practices at the regional level, but should have relevance for SEA processes at all levels. The purpose of the framework is to promote a learning-oriented and integrated use of SEA follow-up in strategic decision making. It helps to identify appropriate tools and their use in the process, and to systematise the use of available data and knowledge across the planning organization and process. It distinguishes three stages in follow-up: scoping, analysis and learning, identifies the key functions and demonstrates the informational linkages to the strategic decision-making process. The associated tool kit includes specific analytical and deliberative tools. Many of these are applicable also ex ante, but are then used in a predictive mode rather than on the basis of real data. The analytical element of the framework is organized on the basis of programme theory and 'DPSIR' tools. The paper discusses three issues in the application of the framework: understanding the integration of organizations and knowledge; understanding planners' questions and analytical requirements; and understanding interests, incentives and reluctance to evaluate

    Full Text Available PURPOSE: The dura mater bioprosthesis was developed in the Department of Cardiopneumology of the Hospital das Clínicas of the University of São Paulo Medical School in 1971. Here, we present the clinical results of the dura mater bioprosthesis over 30 years of follow-up. METHODS: We studied 70 consecutive patients who underwent mitral or tricuspid valve replacement with a dura mater bioprosthesis between January 1971 and August 1972. RESULTS: The early mortality was 10% (7 patients. The follow-up was 87% complete (9 patients were lost to follow-up. Two patients were alive and asymptomatic 30 years after valve replacement; 33 patients underwent reoperations due to valve dysfunction, and 19 died during the follow-up period. At 30 years, the actuarial survival was 49.2 ± 8.6%; freedom from rupture, 27.0 ± 10.2%; freedom from calcification, 78.8 ± 8.6%; and freedom from reoperation, 18.8 ± 7.5%. CONCLUSIONS: The dura mater bioprosthesis played an important role in the treatment of patients with mitral and tricuspid valve disease. The low rate of thromboembolism and the long period of follow-up without evidence of valve dysfunction, which occurred for several of our patients, are important characteristics of these bioprosthesis.A bioprótese de dura-mater foi desenvolvida no Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo em 1971.

    Recurrent pneumonia (RP), i.e., at least two episodes of pneumonia in one year or three episodes ever with intercritical radiographic clearing of densities, occurs in 7.7%-9% of children with community-acquired pneumonia. In RP, the challenge is to discriminate between children with self-limiting or minor problems, that do not require a diagnostic work-up, and those with an underlying disease. The aim of the current review is to discuss a reasoned diagnostic approach to RP in childhood. Particular emphasis has been placed on which children should undergo a diagnostic work-up and which tests should be performed. A pediatric case series is also presented, in order to document a single centre experience of RP. A management algorithm for the approach to children with RP, based on the evidence from a literature review, is proposed. Like all algorithms, it is not meant to replace clinical judgment, but it should drive physicians to adopt a systematic approach to pediatric RP and provide a useful guide to the clinician.

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

    Despite improvements in clinical practice, pneumonia remains one of the leading causes of death worldwide. Pathologic findings from autopsy reports could provide more precise and valid data on characteristics of pneumonia patients. We retrospectively reviewed autopsy reports of deceased patients admitted to the Institute for Pulmonary Diseases of Vojvodina in Sremska Kamenica, Serbia, between 1994 and 2003. The patients were classified into two groups: group 1 (n = 161) comprised patients in whom pneumonia was the main cause of death, while group 2 (n = 165) consisted of patients in whom pneumonia was confirmed at autopsy but had various different causes of death. From 1776 patients who underwent autopsy 326 (18.3%) were diagnosed with pneumonia. The most common underlying diseases were atherosclerosis (29.4%), chronic obstructive pulmonary disease (COPD) (26.7%), and malignancies (20.2%). Pneumonia was the main cause of death in 161 cases (group 1) while in group 2 major causes of death were heart failure (HF) (26.7%), acute myocardial infarction (AMI) (16.4%), and pulmonary embolism (PE) (10.9%). Multilobar involvement (91% vs.27%), pulmonary effusion (29% vs.14%), and lung abscess (23.6% vs.8.5%) were more frequently found in group 1, compared to group 2. In patients with pneumonia who underwent autopsy most common underlying diseases were atherosclerosis, COPD, and malignancies, while major causes of death were: progression of pneumonia, HF, AMI, and PE.

    In 2004, we established a Japan-Taiwan-China collaboration for GBR study in the East-Asian region. This serves as a valuable addiction to the world-wide optical and infrared follow-up network, because the East-Asia region would otherwise be blank. We have been carrying out imaging and spectroscopy follow-up observations at Lulin (Taiwan), Kiso (Japan), WIDGET (Japan) and Xinglong (China). From Xinglong and Kiso, we can locate candidates and obtain early time spectra for afterglows. While WIDGET provides early time observations before the bursts, the high-time resolution for multi-band light curves can be obtained at Lulin. With the data from these sites, we can obtain detailed information about the light curve and redshift of GRBs, which are important to understand the mechanism of the afterglows. Up to March 2005, ten follow-up observations have been provided by this East-Asia cooperation. Two optical afterglows were detected, GRB 040924 and GRB 041006. The results of the two detected afterglows are reported in this paper

    Mycoplasma ovipneumoniae has been isolated from the lungs of pneumonic bighorn sheep (BHS). However experimental reproduction of fatal pneumonia in BHS with M. ovipneumoniae was not successful. Therefore the specific role, if any, of M. ovipneumoniae in BHS pneumonia is unclear. The objective of this study was to determine whether M. ovipneumoniae alone causes fatal pneumonia in BHS, or predisposes them to infection by Mannheimia haemolytica. We chose M. haemolytica for this study because of its isolation from pneumonic BHS, and its consistent ability to cause fatal pneumonia under experimental conditions. Since in vitro culture could attenuate virulence of M. ovipneumoniae, we used ceftiofur-treated lung homogenates from pneumonic BHS lambs or nasopharyngeal washings from M. ovipneumoniae-positive domestic sheep (DS) as the source of M. ovipneumoniae. Two adult BHS were inoculated intranasally with lung homogenates while two others received nasopharyngeal washings from DS. All BHS developed clinical signs of respiratory infection, but only one BHS died. The dead BHS had carried leukotoxin-positive M. haemolytica in the nasopharynx before the onset of this study. It is likely that M. ovipneumoniae colonization predisposed this BHS to fatal infection with the M. haemolytica already present in this animal. The remaining three BHS developed pneumonia and died 1-5 days following intranasal inoculation with M. haemolytica. On necropsy, lungs of all four BHS showed lesions characteristic of bronchopneumonia. M. haemolytica and M. ovipneumoniae were isolated from the lungs. These results suggest that M. ovipneumoniae alone may not cause fatal pneumonia in BHS, but can predispose them to fatal pneumonia due to M. haemolytica infection. Copyright © 2010 Elsevier B.V.

    Objective To determine the extent and pattern of treatment failure (TF) among children hospitalised with community-acquired pneumonia at a large tertiary hospital in Kenya. Methods We followed up children aged 2–59 months with WHO-defined severe pneumonia (SP) and very severe pneumonia (VSP) for up to 5 days for TF using two definitions: (i) documentation of pre-defined clinical signs resulting in change of treatment (ii) primary clinician's decision to change treatment with or without documentation of the same pre-defined clinical signs. Results We enrolled 385 children. The risk of TF varied between 1.8% (95% CI 0.4–5.1) and 12.4% (95% CI 7.9–18.4) for SP and 21.4% (95% CI 15.9–27) and 39.3% (95% CI 32.5–46.4) for VSP depending on the definition applied. Higher rates were associated with early changes in therapy by clinician in the absence of an obvious clinical rationale. Non-adherence to treatment guidelines was observed for 70/169 (41.4%) and 67/201 (33.3%) of children with SP and VSP, respectively. Among children with SP, adherence to treatment guidelines was associated with the presence of wheeze on initial assessment (P = 0.02), while clinician non-adherence to guideline-recommended treatments for VSP tended to occur in children with altered consciousness (P grupos en la distribución de las características clínicas de base de los niños con NMS, se observó que no existían diferencias en FT entre aquellos tratados con el régimen recomendado por las guías versus alternativas más costosas de amplio espectro (diferencias de riesgo 0.37 (IC 95% -0.84 a 0.51). Conclusión Antes de revisar las actuales guías de manejo de casos de neumonía, se requieren definiciones estandarizadas de FT y estudios apropiados de la efectividad del tratamiento de regímenes alternativos.

    In this study, outer membrane proteins (OMPs) of colistin-resistant Klebsiella pneumoniae and Enterobacter asburiae were analyzed. One colistin-susceptible and three colistin-resistant K. pneumoniae sequence type 258 strains as well as one colistin-susceptible E. asburiae and its colistin-heteroresistant counterpart strain were involved in the study. OMP analysis of each strain was performed by microchip method. Matrix-assisted laser desorption ionization time of flight/mass spectrometry (MALDI-TOF/MS) investigation was carried out after separation of OMPs by two-dimensional gel electrophoresis and in-gel digestion. The MALDI-TOF/MS analysis of OMPs in the colistin-susceptible K. pneumoniae found 16 kDa proteins belonging to the LysM domain/BON superfamily, as well as DNA starvation proteins, whereas OmpX and OmpW were detected in the colistin-resistant counterpart strains. OmpC and OmpW were detected in the colistin-susceptible E. asburiae, whereas OmpA and OmpX were identified in the colistin-resistant counterpart. This study demonstrated that OMP differences were between colistin-susceptible and -resistant counterpart strains. The altered Gram-negative cell wall may contribute to acquired colistin resistance in Enterobacteriaceae.

    2012-01-01

    Neonatal follow-up program (NFP) is becoming the corner stone of standard, high quality care provided to newborns at risk of future neuorodevelopmental delay. Most of the recognized neonatal intensive care units in the developed countries are adopting NFP as part of their mandatory care for the best long term outcome of high risk infants, especially very low birth weight (VLBW) infants. Unfortunately, in the developing and in underdeveloped countries, such early detection and intervention programs are rarely existing, mainly because of the lack of awareness of and exposure to such programs in spite of the increasing numbers of surviving sick newborns due to advancement in neonatal care in these countries. This is a review article to explore the Neonatal follow-up programs looking at historical development, benefts and aims, and standard requirements for successful program development that can be adopted in our countries. In conclusion, proper Neonatal follow-up programs are needed to improve neonatal outcome. Therefore all professionals working in the feld of neonatal care in developing countries should cooperate to create such programs for early detection and hence early intervention for any adverse long term outcome in high-risk newborn infants PMID:27493326

    Organising pneumonia is a distinct histopathological entity characterized by intra-alveolar buds of granulation tissue, called Masson bodies, which mainly comprise of activated fibroblasts and loose connective tissue. This histopathologic pattern has been described in idiopathic cases, characterizing cryptogenic organising pneumonia as well as in the context of pulmonary infection, drug-induced pneumonitis and following lung transplantation. Although distinct as a clinical and pathological entity, community organising pneumonia may present with atypical clinical and pathological features, such as intra-alveolar fillings of fibrin balls and organising tissue that resembles acute respiratory distress syndrome or diffuse alveolar damage. The latter characteristics constitute a recently described anatomoclinical entity called acute fibrinous and organising pneumonia. Here, we describe a rare case of acute fibrinous and organising pneumonia, in an otherwise healthy 65-year-old Greek woman who complained of dry cough, fever, weight loss and progressive dyspnoea. She had never been a smoker. Her clinical symptoms showed a rapid deterioration in the two weeks before admission, despite a course of oral antibiotics. After excluding infection and malignancy with routine laboratory tests and flexible bronchoscopy, high resolution computed tomography and video assisted thoracoscopic lung biopsy were performed. Diagnosis was based on radiological features typical of community organising pneumonia coupled with pathologic features characteristic of acute fibrinous and organising pneumonia. The patient was treated with corticosteroids and showed excellent clinical and radiological response three months after treatment initiation. Acute fibrinous and organising pneumonia is an extremely rare pathologic entity, often misdiagnosed as typical community organising pneumonia. To our knowledge, this is the seventh case of acute fibrinous and organising pneumonia in the literature, with no

    Streptococcus pneumoniae is the most common cause of community-acquired pneumonia, but it is undoubtedly underdiagnosed. We used a nested PCR assay (targeting the pneumolysin gene) to detect S. pneumoniae DNA in multiple sample types from 474 adults with community-acquired pneumonia and 183 control patients who did not have pneumonia. Plasma or buffy coat samples were PCR positive in only 6 of the 21 patients with positive blood cultures for S. pneumoniae and in 12 other patients (4 of whom h...

    Full Text Available We present a 7-year follow-up of a 55-year-old male who experienced ventricular fibrillation during the recovery period of exercise testing and refused implantation of an ICD. Normal left ventricular systolic function was found on echocardiographic examination, and coronary angiography revealed only a side branch disease with a vessel diameter of less than 2 millimeters. The patient was discharged on metoprolol and ASA in addition to his previous treatment with lisinopril and simvastatin. Outpatient cardiac evaluation by repeated 24-hour ECG monitorizations (Holter revealed normal findings. On follow up visits every six months for the past seven years, the patient was found to be asymptomatic.

  3. 200 kDa and 160 kDa neurofilament protein phosphatase resistance following in vivo aluminum chloride exposure.

    1994-01-01

    We have used time-course dephosphorylation experiments and two dimensional isoelectric focusing to assess the phosphorylation state of neurofilament (NF) proteins following the intracisternal inoculation of AlCl3. Littermates of New Zealand white rabbits, age 5-6 weeks, were inoculated with either 1000, 750, 500, 250 or 100 micrograms AlCl3 in 0.9% NaCl or 0.9% NaCl alone, killed 48 hours later and the NF-enriched cytoskeletal fraction isolated from the spinal cord. Neurofilamentous inclusions did not occur following inoculums of 100 or 250 micrograms AlCl3, but thereafter developed in increasing quantities in a dosage-dependent manner. Incubation of the NF-enriched fraction with E. Coli. alkaline phosphatase (enzyme: substrate 1:50) induced a replacement of the highly phosphorylated 200 kDa isoform of NFH with a more poorly phosphorylated 170 kDa isoform, confirmed by immunoblot analysis. This reaction was complete within 20 minutes with NF derived from NaCl, 100 or 250 micrograms AlCl3 inoculated rabbits and within 30 minutes for 500 micrograms AlCl3 inoculums. However, residual highly phosphorylated NFH isoforms persisted at 60 minutes for 750 micrograms inoculums and 90 minutes for that derived from 1000 micrograms AlCl3 inoculums. A similar inhibition of phosphatase activity was observed for NFM. Following two dimensional electrophoresis of the NF-enriched isolate, no alteration in the net phosphorylation state of individual NF subunit proteins was observed--regardless of the inoculum. These results demonstrate a dose-dependent induction of neurofilamentous inclusions in spinal motor neurons following intracisternal AlCl3 inoculation accompanied by increasing phosphatase resistance without a demonstrable alteration in NF net phosphorylation state.

    Organising pneumonia (otherwise referred to as bronchiolitis obliterans organising pneumonia) is characterised histologically by plugs of granulation tissue, which are present predominantly within small airways, alveolar ducts and peri-bronchiolar alveoli. This pattern is not specific for any disorder or cause, but is one type of inflammatory response to pulmonary injury, which may be seen in a wide variety of clinical conditions. Typically, organising pneumonia responds very well to corticosteroid treatment; however, a small percentage of patients appear to develop progressive fibrosis.

    Spontaneous pneumothorax is a serious though infrequently reported pulmonary complication of AIDS. An unsuspected lung collapse was discovered via gallium scintigraphy for the study of Pneumocystis carinii pneumonia. Neither the pneumonia nor the pneumothorax were apparent on the most recent chest roentgenogram. In evaluating gallium images during the work-up of AIDS patients with associated pulmonary pathology, the possible complication of lung collapse should be considered. If pneumothorax is suspected on gallium imaging, a chest roentgenogram in expiration must be obtained for prompt delineation of this serious, yet correctable, condition

    In a former study, taste disturbances after tonsillectomy seemed to be more frequent than expected. Eight percent of patients reported subjective taste disorders 6 months after tonsillectomy. Fifteen patients from the initial trial, who reported taste disorders after tonsillectomy, were contacted again for this long-term follow-up. A telephone interview using the same questionnaire addressing the current self-estimate of taste function was performed. At 32 ± 10 months following surgery, two (0.9%) patients still reported suffering from taste disturbance. This long-term follow-up study shows that dysgeusia following tonsillectomy occurs in approximately 1% of patients. These data should be considered when patients are informed about complications after tonsillectomy. Copyright © 2012 The American Laryngological, Rhinological, and Otological Society, Inc.

    To assess the long-term relationship between tree nut consumption and the risk of developing metabolic syndrome (MetS). Nut consumption was collected using a validated 136-item FFQ. The MetS was defined according to the International Diabetes Federation and American Heart Association/National Heart, Lung, and Blood Institute harmonizing definition. The association between nut consumption and MetS was assessed with logistic regression models adjusting for potential confounders. We compared the incidence of MetS between extreme categories of nut intake (> or = 2 servings/week v. never/almost never) after 6 years of follow-up. The SUN Project (Seguimiento Universidad de Navarra, University of Navarra Follow-up) is a prospective cohort study, formed of Spanish university graduates. Information is gathered by mailed questionnaires collected biennially. Nut consumption and MetS information was collected by self-reported data. Participants (n 9887) initially free of MetS or diabetes and followed up for a minimum of 6 years were included. We observed 567 new cases of MetS during follow-up. Participants who consumed nuts > or = 2 servings/week presented a 32% lower risk of developing MetS than those who never/almost never consumed (adjusted OR = 0.68, 95% CI 0.50, 0.92). The inverse association was stronger among participants who were health professionals. Nut consumption was significantly associated with lower risk of developing MetS after a 6-year follow-up period in a cohort of Spanish graduates.

O pericárdio é muito macio, fácil de ser manipulado, suturado e coapta muito bem nas linhas de sutura, resultando uma anastomose hemostática. O seguimento de 9 anos demonstrou um desempenho satisfatório deste substituto vascular biológico, não ocorrendo casos de fibrose, calcificação ou dilatação aneurismática.From October 1989 to May 1997, 40 patients with aortic dissection, aortic aneurysm, aortic coarctation or aorto-iliac occlusive disease, underwent reconstruction of their aorta using crimped bovine pericardial conduits processed in glutaraldehyde. Total reconstruction of ascending thoracic aorta and aortic valve with reimplantation of coronary arteries was performed in 9 patients, single ascending thoracic aorta in 6, descending thoracic aorta in 2, aortic arch in 1, thoracoabdominal aorta in 1 and the abdominal aorta was reconstructed in 21, also including patients undergoing aortoiliac or aortofemoral bypass. Hospital mortality was 20% (8 patients and causes of death were low cardiac output, recurrence of aortic dissection, multiple organ failure and bleeding. Total follow-up was 128.4 patient-years with a mean follow-up of 4 years per patient. Late complications related to the conduit were observed in 4 patients, including a limb obstruction in 1 patient subjected to aorto-femoral bypass and infection in 3, resulting in pseudoaneurysm. All of them underwent reoperations, corresponding to an incidence of 3.1% ± 1.6% per patient-year. There were 5 late deaths and the causes were sudden death, coronary artery disease, pneumonia, septicemia, and metabolic complications of diabetes and renal failure, corresponding to an incidence of 3.9% ± 1.7% per patient-year.

    The outcome indicator of nosocomial infection (NI) in the intensive care unit (ICU) is used to benchmark the quality of patient care in Malaysia. We conducted a three-year prospective study on the incidences of ventilator-associated pneumonia (VAP), risk factors, and patterns of the microorganisms isolated in three ICUs. A follow-up in prospective cohort surveillance was conducted on patients admitted to an adult medical-surgical ICU of a university hospital and two governmental hospitals in Malaysia from October 2003 to December 2006. VAP was detected using CDC criteria which included clinical manifestation and confirmed endotracheal secretion culture results. In total, 215 patients (2,306 patient-days) were enrolled into the study. The incidence of ICU-acquired device-related NI was 29.3 % (n = 63). The device-related VAP infection rate was 27.0 % (n = 58), with a mechanical ventilator utilization rate of 88.7%. The death rate due to all ICU-acquired NI including sepsis was 6.5%. The most common causative pathogen was Klebsiella pneumoniae (n = 27). Multivariate analysis using Cox regression showed that the risk factors identified were aspiration pneumonia (HR = 4.09; 95% CI = 1.24, 13.51; P = 0.021), cancer (HR = 2.51; 95% CI = 1.27, 4.97; P = 0.008), leucocytosis (HR=3.43; 95% CI= 1.60, 7.37; P=0.002) and duration of mechanical ventilation (HR=1.04; 95% CI = 1.00, 1.08; P = 0.030). Age, gender and race were not identified as risk factors in the multivariable analysis performed. The incidence of VAP was comparable to that found in the National Nosocomial Infection Surveillance (NNIS) System report of June 1998. The incidence of VAP was considered high for the three hospitals studied.

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

    Despite being rare cancers, testicular seminoma and non-seminoma play an important role in oncology: they represent a model on how to optimize radiological follow-up, aiming at a lowest possible radiation exposure and secondary cancer risk. Males diagnosed with testicular cancer undergo frequently prolonged follow-up with CT-scans with potential toxic side effects, in particular secondary cancers. To reduce the risks linked to ionizing radiation, precise follow-up protocols have been developed. The number of recommended CT-scanners has been significantly reduced over the last 10 years. The CT scanners have evolved technically and new acquisition protocols have the potential to reduce the radiation exposure further.

    Few studies have examined the incidence of complications from gastro-esophageal reflux disease (GERD) in children and adolescents in primary care. Here we aimed to describe the natural history of GERD in a pediatric population with no reflux esophagitis at initial diagnosis, assessing diagnoses of new esophageal complications and extra-esophageal conditions. We used The Health Improvement Network UK primary care database (which includes data on more than 2 million patients) to identify individuals aged 1-17 years with a first diagnosis of gastro-esophageal reflux or heartburn in the period 2000-2005, via a computerized search followed by a manual review of the patient records. This search identified 1242 individuals with an incident diagnosis of GERD but no record of esophagitis. This cohort was followed-up to detect new diagnoses of esophageal complications and extra-esophageal conditions. During a mean follow-up period of almost 4 years, 40 children and adolescents had a confirmed new diagnosis of reflux esophagitis (incidence: 10.9 per 1000 person-years). No cases of Barrett's esophagus, esophageal stricture or esophageal ulcer were reported. Individuals with GERD had double the risk of an extra-esophageal condition such as asthma, pneumonia, cough or chest pain compared with children and adolescents with no diagnosis of GERD. Children and adolescents with GERD may be at risk of developing reflux esophagitis and a range of other extra-esophageal conditions, but more severe esophageal complications are rare.

    Full Text Available Background: hospital-acquired pneumonia is a constant challenge given the current microbiological spectrum, antimicrobial resistance together with its high mortality, morbidity and hospital costs. Objective: to identify the clinical predictors of pneumonia associated with acute ischemic stroke. Methods: a prospective cohort study was conducted in 201 patients diagnosed with acute ischemic stroke consecutively admitted to the stroke unit of the General Carlos Manuel de Céspedes Teaching Hospital during the first seven days after the onset, from January 2012 through December 2013. The independent predictors of hospital-acquired pneumonia were obtained using multivariable logistic regression. Results: fifty six point seven percent were male. The mean age was 64.17 ± 14.33 years. Cases of hospital-acquired pneumonia associated with stroke accounted for 19, 9 %. Subjects who developed pneumonia were older (68.55 ± 13.51 vs. 63.08 ± 14.36 years, had a lower score in the Glasgow Coma Scale (8.00 ± 2.60 vs. 14.00 ± 2.82, and an increased number of leukocytes at admission (10.888 ± 3.487 vs. 9.233 ± 2.539 × 109/L. The following independent factors were identified: Glasgow Coma Scale ≤ 11 (OR: 26.099; 95 % CI 7.164-85.075, history of chronic obstructive pulmonary disease (OR: 8.896; 95 % CI 1.203-65.779, dysphagia (OR: 7.652; 95 % CI 2.369- 24.720, history of heart failure (OR: 4.583; 95 % CI 1.240- 16.932 and dysarthria/severe motor aphasia (OR: 4.222; 95 % CI 1.374- 12.975. Conclusions: the resulting logistic regression model is valid for predicting post-stroke pneumonia based on data routinely acquired.

    Knowing the most common microorganisms in our environment can help us to make proper empirical treatment decisions. The aim is to identify those microorganisms causing community-acquired pneumonia. An observational, descriptive and prospective study was conducted, including patients over 14 years with a clinical and radiographic diagnosis of community-acquired pneumonia during a 383 consecutive day period. A record was made of sociodemographic variables, personal history, prognostic severity scales, progress, and pathogenic agents. The aetiological diagnosis was made using blood cultures, detection of Streptococcus pneumoniae and Legionella pneumophila urinary antigens, sputum culture, influenza virus and Streptococcus pyogenes detection. Categorical variables are presented as absolute values and percentages, and continuous variables as their means and standard deviations. Of the 287 patients included in the study (42% women, mean age 66±22 years), 10.45% died and 70% required hospital admission. An aetiological diagnosis was achieved in 43 patients (14.98%), with 16 microorganisms found in 59 positive samples. The most frequently isolated pathogen was Streptococcus pneumonia (24/59, 41%), followed by gram-negative enteric bacilli, Klebsiella pneumonia, Escherichia coli, Serratia marcescens and Enterobacter cloacae isolated in 20% of the samples (12/59), influenza virus (5/59, 9%), methicillin-resistant Staphylococcus aureus (3/59, 5%), Pseudomonas aeruginosa (2/59, 3%), Moraxella catarrhalis (2/59, 3%), Legionella pneumophila (2/59, 3%), and Haemophilus influenza (2/59, 3%). Polymicrobial infections accounted for 14% (8/59). A high percentage of atypical microorganisms causing community-acquired pneumonia were found.

    Ibrutinib, an oral inhibitor of Bruton tyrosine kinase, is approved for patients with mantle cell lymphoma (MCL) who have received one prior therapy. We report the updated safety and efficacy results from the multicenter, open-label phase 2 registration trial of ibrutinib (median 26.7-month follow-up). Patients (N = 111) received oral ibrutinib 560 mg once daily, and those with stable disease or better could enter a long-term extension study. The primary end point was overall response rate (ORR). The median patient age was 68 years (range, 40-84), with a median of 3 prior therapies (range, 1-5). The median treatment duration was 8.3 months; 46% of patients were treated for >12 months, and 22% were treated for ≥2 years. The ORR was 67% (23% complete response), with a median duration of response of 17.5 months. The 24-month progression-free survival and overall survival rates were 31% (95% confidence interval [CI], 22.3-40.4) and 47% (95% CI, 37.1-56.9), respectively. The most common adverse events (AEs) in >30% of patients included diarrhea (54%), fatigue (50%), nausea (33%), and dyspnea (32%). The most frequent grade ≥3 infections included pneumonia (8%), urinary tract infection (4%), and cellulitis (3%). Grade ≥3 bleeding events in ≥2% of patients were hematuria (2%) and subdural hematoma (2%). Common all-grade hematologic AEs were thrombocytopenia (22%), neutropenia (19%), and anemia (18%). The prevalence of infection, diarrhea, and bleeding was highest for the first 6 months of therapy and less thereafter. With longer follow-up, ibrutinib continues to demonstrate durable responses and favorable safety in relapsed/refractory MCL.
