RESUMO

<p><b>OBJECTIVE</b>To identify clinical characteristics of hospitalized laboratory-confirmed influenza cases of children under 15 years old, and their risk factors of influenza infection.</p><p><b>METHODS</b>Analyzing the reports of hospitalized laboratory-confirmed influenza cases of children under 15 years old who were detected by the sentinel surveillance systems in 10 provinces from December 2009 to June 2014. Such data as their demographic, medical history, clinical symptoms and signs, treatment and outcome were collected using questionnaires, with their clinical characteristics and their risk factors of influenza infection described.</p><p><b>RESULTS</b>Of the 2 937 severe acute respiratory infection inpatients, 190 (6.5%) were laboratory-confirmed influenza cases. 123 (64.7%) of such confirmed cases were male, and 139 (73.2%) were children under 5 years old, with age median of 3.0 years (IQR: 1.0-5.0 years). 20 (10.5%) of them had at least one chronic medical condition, mostly chronic cardiovascular disease (3.2%), immunosuppressive disease (3.2%), and cancer/tumor (2.6%). Most common clinical symptoms of the cases were fever (92.6%) and cough (88.8%), of which abnormal pulmonary auscultation (51.1%) and abnormal chest X-ray performance (36.1%) were the most common clinical signs. 29 cases (15.8%) had complications, of which pneumonia (15.3%) was most common. 16 cases (8.6%) used antiviral drugs, and 4 cases (2.2%) were admitted into ICU. Risk factor analysis suggested that age < 6 months (OR = 0.406, 95% CI: 0.203-0.815) was a protective factor against influenza infection; and age 5-9 years old (OR = 2.535, 95% CI: 1.059-6.066) was a risk factor for influenza infection.</p><p><b>CONCLUSION</b>Hospitalized laboratory-confirmed influenza cases were found mostly in children under 5 years old. Risk exposure for influenza infection varied among age groups.</p>

RESUMO

Three cases of Good's syndrome with pulmonary lesions in our hospital from June 1,2010 to June 1,2013 were retrospective analyzed and relevant literatures were reviewed.Clinical manifestation,characteristics of pulmonary lesions,diagnosis and treatment were summarized.Abnormality of lymphocyte subpopulation to varying degrees in peripheral blood was detected in all 3 cases.However none showed hypogammaglobulinemia.If thymoma patients developed recurrent respiratory infections,Good's syndrome should be considered.Pulmonary manifestations of Good's syndrome have lesions similar to those of diffuse panbronchiolitis or interstitial lung disease.Early screening of immune competency and treatment for immunodeficiency may improve prognosis.

RESUMO

OBJECTIVE To investigate the value of fibrobronchoscopy and bronchoalveolar lavage in etiologic diagnosis of pneumonia in immunocompromised patients.METHODS The clinical document and results of fibrobronchoscopy and bronchoalveolar lavage in 36 immunocompromised patients with pneumonia were retrospectively analyzed,whose conditions were mainly after organ transplantation and hematologic neoplasia.RESULTS Through fibrobronchoscopy and(or) bronchoalveolar lavage,22 cases(61.1%) were etiologically diagnosed.In 19 cases taking cytomegalovirus(CMV) quantitative PCR test of both peripheral blood and BALF,the positive rate of blood and BALF was 14.3% and 42.9%,respectively(P
