ABSTRACT

The clinical features, imaging findings and pathological manifestations of children diagnosed with acute interstitial pneumonia (AIP) in the Department of Respiratory, Beijing Children′s Hospital, Capital Medical University from January 2016 to December 2017 were retrospectively analyzed.One patient was a girl aged 8 years and 4 months, and the other patient was a boy aged 1 year and 11 months.Both of them had cough and tachypnea for 20 days with transient afebrile.They were diagnosed as Mycoplasma pneumonia and viral pneumonia, respectively, in other hospitals, but the treatment effect was poor.The physical examination results at admission suggested tachypnea, three depression sign (+ ), cyanosis of lips and fingers, no acropachia, and no rales.No abnormality in cardio abdominal and nervous system was detected.Both patients had hypoxemia.The partial pressure of carbon dioxide was normal.The investigations of pathogen were negative.Autoantibody and antineutrophil cytoplasmic antibodies were negative.High resolution CT (HRCT) showed reduced light transmittance of both lungs (especially the lower lung), diffuse bilateral ground glass opacities, consolidation, and traction associated bronchiectasis.The pulmonary histopathology showed di-ffuse alveolar damage, thickened alveolar septum and fibrous tissue in the alveolar cavity.The hyaline membrane was observed in the girl patient.Both patients were treated with corticosteroid.The girl patient had nasal cannula oxygenation, while the boy patient received nasal continuous positive airway pressure (NCPAP) support.They were followed up with improvement.The course of corticosteroid was taped for 8 months and 1 year in the girl patient and boy patient, respectively.After treatment, lung lesions were basically absorbed.

ABSTRACT

Objective To analyze the clinical characteristics of community-acquired influenza virus pneumonia in hospitalized children and improve the clinicians' understanding level of this disease.Methods Data of 70 cases with community-acquired influenza virus pneumonia admitted to the Respiratory Department and Infectious Disease,Beijing Children's Hospital,Capital Medical University,from November 2009 to April 2018 were collected and the clinical characteristics were analyzed.Results Of the 70 cases,61 cases(89.7%) were discharged after improvement.The median age was 3.5 years old,and 50 cases(71.4%) were 0 to 5 years old.There were 29 cases with severe influenza pneumonia,41 cases with mild influenza pneumonia,3 cases died,and 19 cases (27.1%) had underlying diseases.Sixty-four cases (91.4%) were hospitalized in winter and spring.The first symptoms were mainly fever in 64 cases (91.4%) and cough in 65 cases (92.9%),and temperatures were mostly from 39.1 ℃ to 41.0 ℃.Lung auscultation was dominated by moist rales (30 cases,58.8%) and wheezing (8 cases,15.7%).There were many complications of influenza virus pneumonia,including 19 cases with myocardial injury,11 cases with liver function injury,4 cases with toxic encephalopathy,3 cases with electrolyte disturbance,2 cases with multiple organ failure,2 cases with hemophagocytic syndrome,and 1 case with septic shock.Chest radiographic results reveal bilateral inflammation in 40 children (57.1%),prodominatly in lower lobe lesions (39 cases).The common changes were patchy shadow,interstitial parenchymal lesion,ground glass shadow,and pleural effusion.Forty-seven children (67.1%) were infected by influenza A,and 23 children(32.9%) were co-infected.The percentage of severe cases with underlying diseases (68.4%) was significantly higher than that in children without chronic diseases (31.4%),the difference was statistically significant (x2 =7.830,P =0.005).The increase rate of C reaction protein (CRP) in severe cases (54.3%) was significantly higher than that in mild cases (28.6%),the difference was statistically significant (x2 =4.769,P =0.029).Conclusions Community-acquired influenza virus pneumonia in children mainly occurs in winter and spring.It is more common seen in children under 5 years of age.The main clinical manifestations of community-acquired influenza virus pneumonia are high fever and cough,extrapulmonary complications are more common.Most children have moist rales and showed bilateral inflammation and lower lobe lesions in chest radiography.Children with underlying diseases are more likely to develop severe influenza virus pneumonia.Elevated CRP is associated with severe influenza virus pneumonia.Most patients have a good prognosis,but there are still cases of death.

ABSTRACT

Objective To improve the understanding of neonatal-onset pulmonary tuberculosis.Methods The clinical features,laboratory examination and imaging were analyzed in 2 cases with neonatal-onset pulmonary tuberculosis in the Respiratory Department of Beijing Children's Hospital,Capital Medical University.Results The 2 patients were premature twins,were born at 33 +3 weeks of gestation,presented with intermittent cough and transient fever on 26 days after birth.Chest CT scan showed pulmonary multifocal nodules.One case was complicated with pleural effusion,atelectasis and no effectiveness with antibiotics.The untypical pathogen infection was considered.The result of PPD was negative,the result of interferon gamma release array,gastric acid fast staining and mycobacterium tuberculosis culture were positive,finally they were diagnosed with pulmonary tuberculosis.Conclusions The clinical features and imaging of neonatal tuberculosis are always untypical and PPD is negative,which brings difficulties to clinical diagnosis.We should take untypical pathogens into account,such as tuberculosis,when some diseases cannot be explained by common pathogens.

ABSTRACT

Objective To explore the clinical features of chronic granulomatous diseases and Mcleod syndrome caused by continuous X chromosome deletion. Methods The clinical data of two children diagnosed as chronic granulomatous disease and Mcleod syndrome by gene detection were retrospectively analyzed. Results Two males, 4 year 1 month and 1 year 9 month old, were both hospitalized due to persistent pulmonary infections. Both of them had a history of repeated severe infections and BCG vaccine associated lymphadenitis, and were diagnosed as X-linked chronic granulomatous disease for respiratory burst defects and deletion of all CYBB exons. Both of them had retarded motor development, and were diagnosed as DMD for detection of DMD gene exons and muscle speciifc promoter region and exon 1-2 deletion by MLPA. One case was found with obvious echinocytes, the other case showed whole exons deletion of XK gene. Both of them were diagnosed as Mcleod syndrome. Conclusion Continuous X chromosome deletion could lead to combination of Mcleod syndrome, DMD, and X-CGD, which may complicate the condition. Due to the lack of Kx antigen, repeated common blood transfusion can produce relative antibody, which lead to severe hemolytic crisis.

ABSTRACT

Objective To compare the therapeutic effect of Midodrine hydrochloride plus oral rehydration salts,Metoprolol plus oral rehydration salts and simple oral rehydration salts on children with postural tachycardia syn-drome(POTS). Methods One hundred and ninety - two children with POTS were divided into Midodrine hydrochlo-ride plus oral rehydration salts group(84 cases),Metoprolol plus oral rehydration salts group(54 cases)and oral rehy-dration salts group(54 cases). The patients were followed up at the outpatient department after 3 - months treatment. Short - term effect was analyzed by reevaluating the symptom scores,repeating upright test and studying the side effects of the drugs. All the children were followed - up by telephone,mainly investigating on the syndrome recurrence and symptom - free survival by Kaplan - Meier analysis. The follow - up time was 3 to 122(42. 7 ± 24. 3)months. Results Short - term effect showed that the symptom scores were decreased after treatment(t = 21. 536,P ﹤ 0. 001). Head -up test showed that delta heart rate was decreased. The effective rates in the Midodrine hydrochloride plus oral rehydra-tion salts group and the Metoprolol plus oral rehydration salts group were significantly higher than those of the simple oral rehydration salts group(χ2 = 10. 905,P = 0. 004). But no statistical difference was found between the Midodrine hydrochloride plus oral rehydration salts group and the Metoprolol plus oral rehydration salts group(χ2 = 0. 042,P =0. 837). Long - term effect by Kaplan - Meier curve showed that the therapeutic effect of Midodrine hydrochloride plus oral rehydration salts group was significantly higher than any of the other two groups(χ2 = 13. 299,P ﹤ 0. 01),but no statistical difference was found between the Metoprolol plus oral rehydration salts group and the simple oral rehydration salts group(χ2 = 0. 150,P = 0. 699). Conclusions In terms of the short - term result,the effective rates in the Mido-drine hydrochloride plus oral rehydration salts group and the Metoprolol plus oral rehydration salts group were signifi-cantly higher than those of the simple oral rehydration salts group. The therapeutic effect of the Midodrine hydrochloride plus oral rehydration salts was superior to that of the Metoprolol plus oral rehydration salts and the simple oral rehydra-tion salts for POTS children by the long - term follow - up study.

ABSTRACT

<p><b>OBJECTIVE</b>To explore the predictive value of baseline plasma midregional fragment of pro-adrenomedullin level (MR-proADM) on long-term survival of postural tachycardia syndrome (POTS) children treated with midodrine hydrochloride.</p><p><b>METHODS</b>Fifty-three children (male 26, mean age (14.5 ± 4.5) years old) with POTS were included in this study, and all of them were diagnosed as POTS in our department from December 2007 to January 2010. Fifty-three children with POTS were divided into two groups according to the baseline plasma content of MR-proADM. Group I consisted of 35 POTS children with plasma content of MR-proADM > 61.5 ng/L, and the group II consisted of 18 POTS children with plasma content of MR-proADM ≤ 61.5 ng/L. The mean follow-up time was (67 ± 7) months. The orthostatic intolerance symptom score and the symptom free survival were compared between the 2 groups.</p><p><b>RESULTS</b>At the 60 months follow-up, the symptom score of children in group I was significantly lower than that in group II (χ(2) = 4.985, P < 0.05). At 72 months follow up, the symptom score was similar between the 2 groups (χ(2) = 0.004, P > 0.05) while the symptom free survival of group I was significantly higher than that in group II (χ(2) = 4.566, P < 0.05).</p><p><b>CONCLUSION</b>The baseline plasma MR-proADM level is value in predicting the long-term survival of POTS children treated with midodrine hydrochloride.</p>
