Research progress on pathogenicity and mechanism of important virulence factors of Moraxella catarrhalis / 中华检验医学杂志

Moraxella catarrhalis ( Mca) is a kind of gram-negative diplococcus which can exist in the respiratory tract of the human. It could be a non-symptom diplococcus on the health people. Otitis media occurs when the Mca reaches the middle ear along the eustachian tube. Sometimes the patients could suffer from the acute exacerbation of chronic obstructive pulmonary disease or pneumonia due to lung lesions caused by Mca. Little is known about the pathogenesis of the Mca, which leads to an incomplete understanding of its pathogenicity. This review aims to clarify the relationships between the Mca and the related diseases and the mechanism of the significant virulence factors. We hope to raise awareness of Mca and also provide some ideas for clinical diagnosis of relevant diseases it caused.

Regression analysis showed that there was a linear correlation between patient group, course of disease and outcome effect (P<0.05).@*Conclusions@#The respiratory rehabilitation and traditional Chinese medicine exercises "sixth tactic" combined with conventional treatment could release anxiety, depression and negative emotions, and improve clinical symptoms of the patients with COPD.

Impaired pulmonary function after treatment for tuberculosis: the end of the disease? / Comprometimento da função pulmonar após tratamento para tuberculose: o resultado final da doença?

ABSTRACT Objective: To evaluate the prevalence of pulmonary function abnormalities and to investigate the factors affecting lung function in patients treated for pulmonary tuberculosis. Methods: A total of 214 consecutive patients (132 men and 82 women; 20-82 years of age), treated for pulmonary tuberculosis and followed at a local dispensary, underwent spirometry and plethysmography at least one year after treatment. Results: Pulmonary impairment was present in 102 (47.7%) of the 214 patients evaluated. The most common functional alteration was obstructive lung disease (seen in 34.6%). Of the 214 patients, 60 (28.0%) showed reduced pulmonary function (FEV1 below the lower limit of normal). Risk factors for reduced pulmonary function were having had culture-positive pulmonary tuberculosis in the past, being over 50 years of age, having recurrent tuberculosis, and having a lower level of education. Conclusions: Nearly half of all tuberculosis patients evolve to impaired pulmonary function. That underscores the need for pulmonary function testing after the end of treatment.

RESUMO Objetivo: Avaliar a prevalência de alterações da função pulmonar e investigar os fatores que afetam a função pulmonar em pacientes tratados para tuberculose pulmonar. Métodos: Um total de 214 pacientes consecutivos (132 homens e 82 mulheres; 20-82 anos de idade), tratados para tuberculose pulmonar e acompanhados em um dispensário local, foi submetido a espirometria e pletismografia pelo menos um ano após o tratamento. Resultados: O comprometimento pulmonar estava presente em 102 (47,7%) dos 214 pacientes avaliados. A alteração funcional mais comum foi o distúrbio ventilatório obstrutivo (observado em 34,6%). Dos 214 pacientes, 60 (28,0%) apresentaram função pulmonar reduzida (VEF1 abaixo do limite inferior de normalidade). Os fatores de risco para função pulmonar reduzida foram tuberculose pulmonar com cultura positiva no passado, idade acima de 50 anos, recidiva de tuberculose e menor nível de escolaridade. Conclusões: Quase metade de todos os pacientes com tuberculose evolui com comprometimento da função pulmonar. Isso reforça a necessidade de testes de função pulmonar após o término do tratamento.

Analysis of respiratory flow pattern during tidal breathing in seated healthy adults and stable ;chronic obstructive pulmonary disease patients / 中国医师进修杂志

Objective To observe the characteristics of respiratory airflow in healthy adults and stable chronic obstructive pulmonary disease (COPD) patients by analysis of analyzing tidal breathing flow-volume curves (TBFV). Methods Fifteen stable moderate COPD patients (COPD group) and 15 healthy cases without smoking(healthy control group)were enrolled into the study. No bronchodilators were used in patients of COPD group 8 h before test. Pulmonary function test and TBFV in seated position were measured, and the pressure of oral cavity was monitored concomitantly. Results The levels of percentage of vital capacity (VC%), percentage of forced expiratory volume in the first second (FEV 1)/forced vital capacity (FVC) and percentage of maximum mid-expiratory flow (MMEF%) in COPD group were significantly lower than those in healthy control group (P0.05). The levels of tidal expiratory flow at 50%of the remaining tidal volume/PTEF (TEF50/PTEF) and tidal expiratory flow at 25%of the remaining tidal volume/PTEF (TEF25/PTEF) in healthy control group were significantly higher than those in COPD group:0.54 ± 0.13 vs. 0.40 ± 0.12, 0.28 ± 0.13 vs. 0.20 ± 0.06, P<0.01 or<0.05. No differences were found in peak inspiratory pressure (PI max) and peak expiratory pressure (PE max) between two groups. Conclusions The degree of airflow limitation and the effect of bronchodilator in critical patients could be evaluated by analysis of TBFV parameters. The measurement of TBFV is simple and don′t need special technique. It is worth of promoting.

According to the clinical experience, the experts believe that the range of occupational irritant gases should be expanded, and the operation of the problem of smoking, seniority determination and occupational contact history should be challenged during the diagnosis.@*Conclusions@#Since the promulgation in 2011 of the criteria for the diagnosis of chronic obstructive pulmonary disease caused by occupational stimulant chemicals, there have been some problems in the implementation process, which have caused many occupationally exposed to irritating gases to suffer from "occupational chronic respiratory Diseases" without a definitive diagnosis.

Study on the correlation between health education compliance and treatment outcome of chronic obstructive pulmonary disease / 中华健康管理学杂志

Objective To explore the influence of health education and treatment compliance on COPD patients' outcome.Methods 258 subjects (186 males,72 females,average age 75.2±8.5 years) were enrolled from patients diagnosed with COPD between June 2013 to June 2014 in huashan hospital north compus.Study began in July 2014,health condition assessment and grading、telephone follow-up and education were performed once every half a year together with COPD lectures,the number of patients participated in education sessions,and status of smoking cessation,exercise\home oxygen therapy and medication were recorded as indicators for health education compliance.Clinic/hospital stay and cost,condition change were also recorded.The study ended in December 2015 with final assessments of conditions and classification of patient outcome.Multiple logistic regression was used to analyze factors influencing the COPD patient's outcome;Independent sample t test was applied to compare different compliance in patients with outpatient and hospitalization per-time cost difference.Results Higher reimbursement ratio,the better adherence for health education,no complications and the low grade of disease classification at the beginning of the study were protective factors (OR=10.35,2.147,5.791,4.51,P＜0.05);Underweight to normal weight,5 times or more acute attacks during during the study,poor health education compliance were risk factors for disease progression (OR=0.031,0.131,0.010,P＜ 0.05);Never exercise and never participating in health education management are the risk of illness/death((OR=6.793,P=0.005,95％CI:1.766～26.125) vs.(OR=11.872,P=0.002,95％CI:2.525～55.815));for mild COPD patients,these never participating in health education management had a higher per hospitalization than patients with health education management (6 619 yuan,t=2.681,P=0.010).The outpatient cost of more severe COPD patients who are smoking or quitted smoking in less than 5 years was higher than these quitted smoking more than 5 years (985 yuan,t=-2.225,P=0.028).Conclusions Health education management can help medical staff to provide guidance to patients to quit smoking,encouraging the regular use of home oxygen therapy,doing more exercise,taking prescription of preventive drugs,these will in turn improve patient compliance for disease control and prevention.These efforts can effectively slow disease progression and improve patient outcomes,reduce medical costs,reduce the burden of the family and society.

Recurrent Desaturation Events due to Opioid-Induced Chest Wall Rigidity after Low Dose Fentanyl Administration / 대한구급학회지

Opioid-induced chest wall rigidity is an uncommon complication of opioids. Because of this, it is often difficult to make a differential diagnosis in a mechanically ventilated patient who experiences increased airway pressure and difficulty with ventilation. A 76-year-old female patient was admitted to the intensive care unit (ICU) after surgery for periprosthetic fracture of the femur neck. On completion of the surgery, airway pressure was increased, and oxygen saturation fell below 95% after a bolus dose of fentanyl. After ICU admission, the same event recurred. Manual ventilation was immediately started, and a muscle relaxant relieved the symptoms. There was no sign or symptom suggesting airway obstruction or asthma on physical examination. Early recognition and treatment should be made in a mechanically ventilated patient experiencing increased airway pressure in order to prevent further deterioration.

Effects of Salmeterol/Fluticasone on Bone Metabolism and Bone Density in the Patients with Moderate Chronic Obstructive Pulmonary Disease(COPD) / 天津医药

Objective To observe the effects of salmeterol/fluticasone on the bone metabolism and bone density of the patients with moderate COPD and whether the effects is relate with inhaled corticosteroid course. Methods Sixty pa-tients with COPD were divided into 2 groups by random digit table. Patients in experimental group (n=30) were given conven-tional therapy with salmeterol/fluticasone one inhale(bid) for continuously 12 months while patients in control group (N=30) were given conventional therapy without any glucocorticoid.The bone mineral density (BMD) of the femoral triangle in all patients were measured by DXA before therapy, 3 months and 12 months after therapy. At the same time, biochemical indi-cators that are correlated with bone metabolism include bone gla protein (BGP) and alkaline phosphatase (ALP) were mea-sured by radioimmunoassay. Results The BMD, BGP and ALP of patients in experimental group and in control group be-fore therapy, 3 month and 12 month after therapy were compared. There is no significant difference (P>0.05) between these two groups before therapy and after 3 month but significant difference was shown after 9 months (P<0.05). Conclusion Short period inhaling salmeterol/fluticasone in patients with COPD is safe. But long-term inhaling salmeterol/fluticason may lead to decline of the bone density in patients with COPD.

The treatment group was intervened by grain-sized moxibustion in addition to the above treatments.Two weeks later, the two groups were compared in the use of antibiotics, C-reactive protein, and therapeutic efficacy.ResultThe use of antibiotics and the content of C-reactive protein in the treatment group were less than that in the control group.ConclusionFor patients under the acute attack of COPD due to accumulation of phlegm and stasis, grain-sized moxibustion can shorten the time of using antibiotics and descend the content of C-reactive protein by modulating inflammation.

Bronquiolite obliterante: perfil clínico e radiológico de crianças acompanhadas em ambulatório de referência / Bronchiolitis obliterans: clinical and radiological profile of children followed-up in a reference outpatient clinic / Bronquiolitis obliterante: perfil clínico y radiológico de 35 niños acompañados en ambulatorio de referencia

OBJETIVO: Descrever as características clínico-radiológicas dos pacientes com bronquiolite obliterante. MÉTODOS: Estudo descritivo e retrospectivo. Foram coletados dados de pacientes diagnosticados com bronquiolite obliterante entre 2004 e 2008 no Ambulatório de Pneumologia Pediátrica do Hospital Infantil Albert Sabin, no Ceará. O diagnóstico foi baseado em critérios clínicos e tomográficos. Foram avaliados história prévia, quadro clínico por ocasião do diagnóstico, exames complementares e evolução. RESULTADOS: Foram identificados 35 pacientes com bronquiolite obliterante. Houve predominância do sexo masculino (3:1). A média de idade no início dos sintomas foi de 7,5 meses e, por ocasião do diagnóstico, 21,8 meses. Os achados clínicos mais frequentes foram estertores/sibilos, taquipneia, dispneia e deformidade torácica. A etiologia pós-infecciosa destacou-se como a principal causa de bronquiolite obliterante. As alterações encontradas com maior frequência à radiografia e à tomografia computadorizada de alta resolução de tórax foram espessamento peribrônquico e padrão de perfusão em mosaico, respectivamente. O tratamento instituído aos pacientes foi variável e individualizado. A maioria deles evoluiu com melhora clínica durante o seguimento, apesar da persistência da sintomatologia respiratória. CONCLUSÕES: A presente casuística de bronquiolite obliterante mostrou predominância de pacientes do sexo masculino e de etiologia pós-infecciosa, corroborando os dados da literatura. Os achados tomográficos mais encontrados foram semelhantes aos descritos em trabalhos anteriores (perfusão em mosaico, espessamento peribrônquico e bronquiectasias). Ainda faltam evidências acerca do tratamento para esta doença. O diagnóstico de bronquiolite obliterante foi tardio, necessitando da suspeição clínica por parte dos pediatras frente a lactentes chiadores graves e perenes.

OBJECTIVES: To describe the clinical and radiological characteristics of patients with bronchiolitis obliterans. METHODS: This is a retrospective and descriptive study. Data were collected from patients diagnosed with bronchiolitis obliterans between 2004 and 2008 in the Pediatric Pulmonology Clinic of Hospital Infantil Albert Sabin, in Ceará, Northeast Brazil. Such diagnosis was based on clinical and tomographic criteria. Previous history, clinical findings at the diagnosis, complementary exams, and follow-up data were evaluated. RESULTS: 35 children diagnosed with bronchiolitis obliterans were identified. There was a predominance of male patients (3:1). The mean age at the onset of symptoms was 7.5 months, and bronchiolitis obliterans was diagnosed at a mean age of 21.8 months. The most common clinical findings were crackles/wheezing, tachypnea, dyspnea, and chest deformity. Post-infectious etiology was the main cause of bronchiolitis obliterans. Predominant findings at chest X-ray and high resolution computed tomography were peri-bronchial thickening and mosaic pattern, respectively. The treatment was variable and individualized. The majority of patients improved during follow-up, despite the persistence of respiratory symptoms. CONCLUSIONS: In this study, the predominance of male patients and post-infectious etiology was noted, corroborating scientific literature. The most common tomographic findings were similar to those described in previous studies (mosaic pattern, peri-bronchial thickening, and bronchiectasis). Evidence about the treatment of this disease is still lacking. The diagnosis was delayed, which indicates that clinical suspicion of bronchiolitis obliterans is necessary in children with persistent and severe wheezing.

OBJETIVO: Describir las características clínico-radiológicas de los pacientes con bronquiolitis obliterante acompañados en el Ambulatorio de Pneumología Pediátrica del Hospital Infantil Albert Sabin en la provincia de Ceará (Brasil). MÉTODOS: Estudio descriptivo y retrospectivo. Se recogieron datos de pacientes diagnosticados con bronquiolitis obliterante entre 2004 y 2008. El diagnóstico se basó en criterios clínicos y tomográficos. Se evaluaron la historia previa, el cuadro clínico en el momento del diagnóstico, exámenes complementares y evolución. RESULTADOS: Se identificaron 35 pacientes diagnosticados con bronquiolitis obliterante. Hubo predominancia de los pacientes del sexo masculino (3:1). El promedio de edad en el inicio de los síntomas fue de 7,5 meses y, en el momento del diagnóstico, 21,8 meses. Los hallazgos clínicos más frecuentes fueron ruidos respiratorios/silbidos, taquipnea, disnea y deformidad torácica. La etiología post-infecciosa se destacó como la principal causa de bronquiolitis obliterante. Las alteraciones encontradas con más frecuencia a la radiografía y a la tomografía computadorizada de alta resolución del tórax fueron espesamiento peribrónquico y estándar de perfusión en mosaico, respectivamente. El tratamiento instituido a los pacientes fue variable e individualizado. La mayoría evolucionó con mejora clínica durante el seguimiento, a pesar de la persistencia de la sintomatología respiratoria en grados variables. CONCLUSIONES: La presente casuística de bronquiolitis obliterante mostró predominancia de pacientes del sexo masculino y de etiología post-infecciosa, corroborando los datos de la literatura. Los hallazgos tomográficos más encontrados fueron semejantes a los descriptos en trabajos anteriores (perfusión en mosaico, espesamiento brónquico y bronquiectasias). Todavía faltan evidencias sobre el tratamiento para esta enfermedad. El diagnóstico de bronquiolitis obliterante fue tardío, siendo necesaria la sospecha clínica por parte de los pediatras frente a lactantes silbadores graves y perennes.

The correlation between the paired inspiratory and expiratory three-dimensional quantitative CT and pulmonary function test in chronic obstructive pulmonary disease / 中华放射学杂志

Objective To investigate the correlation between the paired inspiratory and expiratory quantitative CT and pulmonary function tests (PFTs) in patients with chronic obstructive pulmonary disease (COPD).Methods A total of 84 patients with COPD were enrolled.For each patient,CT scan was performed in deep inspiration and expiration.Using automatic post-processing software,a three-dimension quantitative measurement was employed to assess the CT parameters of emphysema and air trapping.The correlation between CT and PFT was evaluated by the Spearman rank correlation test and multivariate linear regression analysis.Results The percent 1 [Perc1,(-984.28 ± 17.93) HU] and percent 15 [Perc15,(-948.35 ± 22.26) HU] from the CT parameters of emphysema were positively correlated with the forced expiratory volume in 1 second predicted (FEV1％,48.69 ± 23,47),the ratio of forced expiratory volume in 1 second over forced vital capacity [FEV1/FVC,(45.89 ± 15.36)％,r =0.454.-0.67,P ＜0.01],was negatively correlated with the ratio of residual volume to total]ung capacity [RV/TLC,(61.32 ±14.48)％].The other CT parameters of emphysema index (EI) and the parameters of air trapping,the change in relative lung volume with attenuation values from-860 to-950 HU [RVC-860--950,(17.66 ±22.36)％],the expiration to inspiration ratio of mean lung density (MLDex/in,0.93 ± 0.06),the expiration to inspiration ratio of lung volume(LVex/in,0.71 ± 0.14) had negative correlations with logFEV1 ％,FEV1/FVC (r=-0.48--0.69,P＜0.01) and positive correlations with RV/TLC (r =0.41-0.66,P ＜0.01).The further univariate linear regressions showed that EI,Perc1,Pere15,RVC-860--950,MLDex/in,LVex/in were correlated with the parameters of PFTs (R square values of the regression equation,ranged from 0.27 to 0.66,P ＜ 0.01).After the pairwise combinations of the parameters of emphysema and air trapping,multivariate stepwise regressions showed better R square values from 0.66 to 0.85.Conclusions CT parameters of emphysema and air trapping can reflect pulmonary function in COPD patients.The combinations of the two types of CT parameters are more correlated with the PFTs parameters.
