OBJECTIVELeukocyte adhesion deficiency type 1 (LAD-I) is rare. We present 1 case of LAD-I patient diagnosed by gene analysis. His clinical manifestations and genetic mutation features are analyzed in this article.
METHODThe clinical material of the LAD-I patient who was diagnosed by gene analysis was retrospectively analyzed.
RESULTThe patient was a 2-month-old boy. He had a complaint of recurrent fever and cough for 30 days. Pulmonary CT indicated a small to moderate quantity pleural effusion on the right side. His peripheral blood leukocyte and C-reactive protein (CRP) was always significantly higher than normal. After hospitalization he had diarrheal diseases, routine stool test showed 2 RBC cells/high power (HP), WBC 30 cells/HP, stool cultures were negative, digestive tract ultrasonography showed an array of defects, in the sigmoid colon and rectal mucosa suggestive of ulcerative colitis. He was treated with cefoperazone and sulbactam and vancomycin. He had a history of impetigo in his neonatal period and without delayed umbilical cord exfoliation. His family history was normal. ITGB2 genetic mutation analysis revealed a homozygous mutation (1062A > T). His parents did not participate in this study. He had no fever but had diarrheal disease after 1 month of follow up.
CONCLUSIONThis patient had suffered from impetigo, pleural effusion, diarrheal diseases, markedly increased peripheral white blood cell and ITGB2 genetic mutation analysis showed that homozygous mutation (1062A > T). He received a diagnosis of LAD-I.

BACKGROUNDSeveral genetic polymorphisms in the endothelial nitric oxide synthase (eNOS) gene are associated with the pathogenesis of rheumatoid arthritis (RA). The objective of the present study was to investigate whether the two SNPs (T-786C and G894T) of the eNOS gene are associated with rheumatoid arthritis risk in a northern Chinese population.
METHODSIn this study, the eNOS genes T-786C and G894T were studied in 196 cases with rheumatoid arthritis and 201 healthy controls with gender, age and ethnicity matched. The two SNPs were genotyped using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The analyses of association were statistically compared using the chi-square test with SPSS software for Windows.
RESULTSThe frequency of the -786C allele was significantly higher in the rheumatoid arthritis patients than in the healthy controls (19.64% vs. 14.18%, P < 0.05). However, the 894T allele of the eNOS gene was not increased in the rheumatoid arthritis patients compared to the healthy controls.
CONCLUSIONSIndividuals with the -786CC genotype have an increased risk of rheumatoid arthritis. Further study with an increased sample size is necessary for the study of the role of this SNP in rheumatoid arthritis.

OBJECTIVETo introduce the early clinical features and the main points of diagnosis and treatment of children with pancreatic pleural fistula presenting massive bloody pleural effusion.
METHODThe clinical data of symptoms, signs, laboratory examination, diagnosis and treatment methods of pancreatic pleural fistula in a child are presented.
RESULTA 4-year-old boy presented with one month history of intermittent fever, cough, chest tightness and chest pain. His pleural effusion collected from three thoracic closed drainage was hemorrhagic. He had no positive abdominal signs. His abdominal B-mode ultrasonography showed rough pancreatic echo. The levels of amylase in blood and pleural fluid were 495 U/L and 35 938 U/L, respectively. There was a fistulous tract from the thoracic cavity leading to the pancreas at thoracic surgical exploration. The child was cured by total parenteral nutrition, intravenous infusion of somatostatin and a stent placed in the pancreatic duct by endoscopic retrograde cholangiopancreatography (ERCP).
CONCLUSIONThe child with pancreatic pleural fistula in early stage mainly present respiratory symptoms and lack abdominal symptoms, so the diagnosis and treatment is often delayed. Significant increase of pancreatic amylase level in pleural effusion can be an important clue and basis for the diagnosis. If conservative therapy fails, the examination and treatment with ERCP should be considered.

OBJECTIVETo explore diagnosis and treatments of invasive pulmonary aspergillosis (IPA) in children with non-hematologic diseases.
METHODTwenty one patients without hematological malignancy were diagnosed with proven or possible IPA from July 2002 to June 2008. The risk factors, clinical manifestations, chest radiographic findings, microbiological and histopathological evidence, diagnostic procedures, treatment and prognosis were retrospectively reviewed.
RESULTFive children had proven IPA, and 16 patients had possible IPA. Thirteen children were classified as having acute invasive pulmonary aspergillosis (AIPA), eight children as having chronic necrotizing pulmonary aspergillosis (CNPA). Definitive diagnosis of primary immunodeficiency (PID) was made in 6 children (4 with chronic granulomatous disease, 2 with cellular immunodeficiency); three children were suspected of having PID. Corticosteroids and multiple broad-spectrum antibiotics had been administered in 5 patients (3 of these 5 patients also had invasive mechanical ventilation). Two children had underlying pulmonary disease. Three patients had unknown risk factors. Among these three patients, two had history of environmental exposure. Fever and cough were present in all the children. Fine rales were found in nineteen children. Six children had hepatosplenomegaly. The common roentgenographic feature of AIPA in 13 patients was nodular or mass-like consolidation with multiple cavity. "air-crescent" was seen in 10 of patients with AIPA. Lobar consolidation with cavity and adjacent pleural thickening was found in all children with CNPA. The positive rate of sputum and/or BALF culture in AIPA and CNPA were 72.1% and 22.4%, respectively. A large number of septate hyphae on wet smear were found in all of the children whose sputum and/or BALF culture were positive. Lung biopsy was performed in 3 children with CNPA, and necrosis, granulomatous inflammation, as well as septate, branching hyphae were observed on histopathologic examination. Fifteen children were treated with anti-fungal therapy (amphotericin B, voriconazole, itraconazole and caspofungin used alone or in combination), symptoms and lung lesions resolved in 12 children. Three children died. Six children did not receive anti-fungal therapy and died. The side effects of amphotericin B include chill, fever, hypokalemia and transient increase in BUN, none of which needed discontinuation of the antifungal therapy. Children had a good tolerance to fluconazole and caspofungin, there were no apparent side effects.
CONCLUSIONMost of the children without hematologic diseases who suffered from invasive pulmonary aspergillosis had risk factors or exposure history. Roentgenographic findings were relatively characteristic for invasive pulmonary aspergillosis. Risk factors and roentgenographic findings were clues to consider clinically invasive pulmonary aspergillosis. Sputum culture was the key point to clinical diagnosis. The patients in whom the antifungal therapy was initiated early had a good outcome.

OBJECTIVETo investigate clinical characteristics and predictive factors of refractory Mycoplasma pneumoniae pneumonia (RMPP) in children so as to recognize and treat the disease earlier.
METHODThe data including febrile time, inflammatory markers (WBC, neutrophil, CRP) and radiological features of 213 children hospitalized with Mycoplasma pneumoniae pneumonia (MPP) (72 with refractory MPP and 141 with mild MPP were retrospectively analyzed). The primary diagnostic criteria of refractory MPP: the patient's condition still deteriorates after treatment with macrolides for more than 5 days. The independent variables which had significant difference in univariate analysis was analyzed by multivariate logistic regression analysis. The predictive criteria of RMPP were further applied in 100 other patients prospectively. Kappa test was used to evaluate the accuracy rate.
RESULTRefractory MPP patients: febrile time was more than 10 days, white blood cell (WBC) count was (3.8 - 18.5)×10(9)/L in peripheral blood routine test, CRP was 38 mg/L - > 160 mg/L, large lobar consolidation with high density (> 2/3 pulmonary lobe, CT value 40 - 50 HU, without air bronchogram). Mild MPP patients: febrile time was less than 10 days, CRP was often less than 40 mg/L. Independent risk factors for RMPP were febrile time, CRP, large consolidation area with high density in lungs with or without pleural effusion (OR = 1.586, P = 0.017; OR = 4.344, P = 0.001; OR = 2.660, P = 0.012), CT value 40 - 50 HU which were demonstrated by logistic regression analysis. The specificity, sensitivity and Youden index for this diagnostic test were respectively 0.96, 0.94 and 0.90 at a CRP cut off of 40 mg/L. The sensitivity, specificity, and Kappa value for the above criteria to diagnose RMPP were respectively 0.96, 0.94 and 0.9.
CONCLUSIONThe predictive factors for RMPP are febrile time (> 10 days), CRP (> 40 mg/L), large lobar consolidation with high density (> 2/3 pulmonary lobe, CT value > 40 HU with or without pleural effusion) for the purpose of treating earlier.

OBJECTIVECystic fibrosis (CF) is rare in Chinese mainland. We present two cases of CF patients diagnosed by gene analysis. Their clinical manifestations and genetic mutation features are analyzed in this article. It will be of special interest to pediatricians in recognition of CF.
METHODThe clinical material of two CF patients who were diagnosed by gene analysis was retrospectively analyzed.
RESULTThe first patient is a 13-year-old girl. She had a complaint of recurrent fever and cough for 6 months, expectoration for 2 months and hemoptysis for 20 days. After 3 months of her birth, she was operated on for bullae of lung. She was susceptible to upper respiratory tract infection. There was no family history of recurrent wheeze and other special diseases. Aspergillus fumigatus specific IgE was at grade 3 and aspergillus fumigatus IgG was high. Pseudomonas aeruginosa was positive in sputum culture. Sweat testing was performed and Na+ was higher. Pulmonary CT indicated bronchiectasis. Nasal sinus CT showed optical density of soft tissue within maxillary sinus and chronic bilateral sinusitis. The electron microscopy of cilia suggested immobile cilia syndrome. A heterozygotic mutation (263T > G, 2909G > A) was found after CFTR genetic mutation analysis. Both her parents were carriers. She was treated with inhalation of nebulized hypertonic saline and postural drainage for a long time. And she got better during a follow up period of 1 year. The second patient was a 10-year-old girl who complained of recurrent expectoration for 3 years and shortness of breath for half a year. She had a history of sinusitis and steatorrhea. The family history was normal. Both the lipase and insulin level in blood serum was lower.Pseudomonas aerugino and Aspergillus fumigatus were both positive in sputum culture. Aspergillus fumigatus IgE was normal. Pulmonary CT indicated bronchiolitis and bronchiectasis. Nasal sinus CT showed bilateral maxillary sinusitis. CFTR genetic mutation analysis revealed a homozygous mutation (3196C > T). Her parents and relatives did not participate in this study. Unfortunately, this child died of respiratory failure 3 months after discharge.
CONCLUSIONCFTR gene mutation was a main cause of CF. Common symptoms are those of bronchiectasis, pancreatitis and sinusitis. The two Chinese patients were diagnosed by gene analysis. One had a heterozygous mutation (263T > G, 2909G > A) and the other had a homozygous mutation (3196C > T), not ΔF508 which is common in western countries.

OBJECTIVETuberculosis is still a public health problem. Host genetic factors, such as polymorphisms in NRAMP1 gene, may play a role in the development of tuberculosis. To clarify the effect of NRAMP1 gene polymorphisms on the development of childhood tuberculosis, the association of NRAMP1 gene polymorphisms with susceptibility to tuberculosis in the ethnic Han Chinese children was investigated.
METHODSFrom January 2005 to March 2008, 130 ethnic Han children with tuberculosis (TB group) were enrolled. Three hundred and ninety hospitalized ethnic Han children for physical examination in the surgery department were used as the control group. The controls were matched with tuberculosis children by age, sex and area. PCR-RFLP analysis was performed on DNA samples to identify allele genotypes of INT4 and D543N in NRAMP1 gene. Genotype frequency differences between tuberculosis patients and controls were analyzed using x2 test.
RESULTSNo statistical difference was found in the genotype frequency of variants G/C and C/C at the INT4 locus between the TB and the control groups. At the D543N locus, the frequency of genotype variants (G/A and A/A) was significantly higher in the TB group (34/130) than that in the control group (66/390) (x2=5.349, P<0.05; OR=1.74, 95%CI=1.08-2.79). When stratified by sex, differences in the genotype distribution were observed only in females at the D543N locus, which the variant genotypes were higher in the TB group (16/52) than in the control group (21/155) (x2=7.866, P<0.05; OR=2.84, 95%CI=1.34-5.99). For males, there was no difference between the TB and the control groups. At the INT4 locus, no difference was observed between the two groups in boys and girls.
CONCLUSIONSGenotypic variation at the D543N locus in NRAMP1 gene may be associated with susceptibility to tuberculosis in ethnic Han Chinese children. Variant genotypes in NRAMP1 gene (G/A and A/A) may be susceptible genotypes to tuberculosis in ethnic Han Chinese children. Girls with variant genotypes were more susceptible to tuberculosis.

OBJECTIVEStreptococcus pneumoniae necrotizing pneumonia (SPNP) was reported elsewhere but not in China yet. Inappropriate treatment due to poor recognition of this disease could influence its prognosis. This paper presents the clinical characteristics, diagnosis and treatment of SPNP hoping to elevate pediatrician's recognition level for this disease.
METHODClinical manifestations, radiological findings, treatment and prognosis of 20 patients (9 boys, 11 girls) who had been hospitalized with SPNP in Beijing Children's Hospital from 2004-2011 were retrospectively analyzed.
RESULTThe patients included in this study aged from 9 months to 6 years [(27.9 ± 15.8) m] and were healthy before admission. They were febrile for 8 to 50 days [(27.7 ± 13.5) d] and hospital day was 24 - 55 days [(36.5 ± 8.3) d]. The general condition of all subjects was relatively poor and they all had fever and cough. One child had moderate fever and nineteen children had high fever. Dyspnea was found in sixteen children. Fine rales were found on auscultation in 18 children, among whom diffuse wheeze appeared in 4 children, and wheezy phlegm was found in two children. Signs of pleural effusion were discovered in all cases by physical examination and chest X-ray. White blood cell (WBC) count was 16.2 - 60.95×10(9)/L and neutrophil was 70.5% - 80.2% in peripheral blood routine test. Erythrocyte sedimentation rate (ESR) was 44 - 109 mm/h [(69.6 ± 16) mm/h]and C-reactive protein (CRP) was 80 - > 160 mg/L. The pleural effusion biochemistry and routine test revealed a WBC count of 6400×10(6)/L-too much to count, polykaryocyte of 51% - 90%, glucose of 0.02 - 1.8 mmol/L, protein of 32 - 51 g/L and LDH of 5475 IU/L-or higher. Pleural effusion culture in all cases and blood culture in 2 cases was positive for Streptococcus pneumoniae. Chest X-ray or CT revealed high density and well-distributed lobar consolidation in one lung or two lungs initially. Single or multiple low density lesions in the area of lobar consolidation were found a week later, accompanied by multiple cystic shadow or cavity at the same time or afterwards. Bulla of lung appeared later. Pleural effusions were found in all patients. Seven cases complicated with hydropneumothorax, two with otitis media, one with heart failure, one with cardiac insufficiency. Seventeen patients were treated with vancomycin or teicoplanin or linezolid two with amoxicillin and clavulanate potassium. Other two patients had been treated with meropenem and cephalosporin antibiotics respectively before admission, and they had been at recovery stage when they were hospitalized. Thoracic close drainage and thoracoscopy were performed respectively in 18 cases and 3 cases, respectively. After a follow up of more than 6 months, chest CT showed that almost all lesions in lungs recovered during 4-6 months. No one received pneumonectomy.
CONCLUSIONSPNP has special manifestations. The incidence in infants is higher. Patients' general condition is poor and febrile course is relatively long. All patients manifested fever and cough, with a presence of dyspnea in most of them. WBC, neutrophil and CRP elevated apparently. The characteristic of pleural effusion indicates empyema. In early stage, the chest X-ray and CT showed high-density lobar lesions, followed by low-density lesions and cyst gradually. Bulla of lung and/or hydropneumothorax may appear at the late stage. But if diagnosed and treated promptly, the prognosis of SPNP was relatively good.
