目的 回顾性分析常规放射检查中儿童胸部复合型骨折漏诊的原因,并且探讨多层螺旋CT后处理技术在儿童胸部复合型骨折中的诊断价值。方法 搜集本院2012年1月—2015年8月间因外伤行胸部照片和CT扫描的外伤患儿共123例,男81例,女42例,年龄9个月～15岁,平均年龄4.3岁。所有病例在完成胸部照片后1~3 d,进行胸部容积CT扫描,并对数据进行三维重建后处理,其结果与常规DR检查结果相比较。结果 在123例患儿中,常规胸部DR片显示明确胸部骨折39例61处,其中胸部单纯性骨折24例,胸部复合型骨折15例。可疑骨折48例;36例未见明确骨折但存在胸部合并症。CT检查显示明确的胸部骨折76例,142处,其中胸部单纯性骨折42例,胸部复合型骨折34例。与胸部DR平片相比,CT显示胸部新增骨折有18处在单纯性骨折病例中,63处在复合型骨折病例中。CT重建技术对复合型骨折的检出率高于DR平片,差异有统计学意义(P＜0.05)。结论 胸部CT容积扫描并综合运用三维重建技术处理,可以提高胸部复合型骨折的检出率,相对于常规放射照片更能提供详细和直观的信息,包括骨折部位、类型、程度以及邻近结构的损伤,并对治疗方案的选择及预后的评估有重要指导价值。

Objective To investigate the reasons for missed diagnoses of children's chest complex fractures in chest radiographs and to discuss the value of multi-slice spiral CT (MSCT) reconstruction in the diagnosis of children's chest complex fractures. Methods 123 children underwent chest digital radiography(DR) and MSCT scans after traumas were collected in our hospital between January 2012 and August 2015. This population consisted of 81 male and 42 female patients, with a mean age of 4.3 years(range from 9 months to 15 years). All participants underwent chest MSCT scans in 1-3 days after completing chest DR, and then we used 3D reconstruction to process the data and compared the results with those processed by DR. Results By chest DR tests we identified 39 cases (61 places) out of 123 participants with 24 simple fractures, 15 complex fractures. And 48 chest fractures were suspected. We also identified 36 cases had chest complications without fracture. By MSCT scans 76 cases (142 places) were identified, among which 42 were simple and 34 were complex. Compared with chest DR, MSCT scans can identified 18 more places of simple fractures and 63 more places of complex fractures. It was statistically significant higher detection rate of MSCT scan than DR. Conclusion Chest MSCT scan combined 3D reconstruction technology can increase the detection rate of chest complex fracture. Compared with DR, it provides more detailed and visualized information, including fracture position, type, severity and adjacent structure damage. It has important guiding value on the selection of therapy and prognosis evaluation.

Methods Selected 129 children with bacterial meningitis all cases were divided into adverse outcome group and favorable outcome group.According to the incidences of different kinds of sequelae,The risk factor effecting bad prognosis were studied. Results A total of 80 children were successfully followed.Of them,12 might only have mild sequelae and 13 had serious sequelaes.Among these children who had serious sequelae,11 of them had mental retardation,8 of them had motor deficit,4 of them had bilateral hearing loss and 4 of them had secondary epilepsy.10 children had multiple serious sequelae,thes most common multiple impairment combinations were mental retardation plus motor deficit.48 parents of the children completed the Child Behaviour Checklist and found out 17(35.42%)of their children had behavioral disorders.Adverse outcome group and favorable outcome group,the length of fever(>7 days),repeated convulsions after admission(≥3 times),coma(Glasgow coma scale score <8 points),septic shock,abnormal pupils,limb movement disorder.There were significantly difference between the two groups(P＜ 0.05). Conclusions This study showed that there are different kinds of sequelaes of children with bacterial meningitis,it indicated that these children should be follow-up to track the effect.On the other hand,this study found out that the high risk factors with adverse outcome might be coma,septic shock and so on.It indicated that if we could identify the high risk factors in the early stage and then interpose them immediately,it might beneficial to improve the quality of life of the children.

Objective To investigate the molecular characteristic of Community-acquired Methicillin-resistant Staphylococcus aureus(CA-MRSA) isolates from pediatric patients in Guangzhou. Methods 65 non-duplicate strains of Community-acquired Methicillin-susceptible Staphylococcus aureus(CA-MSSA) isolated from our hospital in 2009-2014 were investigated. Panton-valentine leukocidin(PVL) gene was detected by polymerase chain reaction(PCR). The sequence type (ST) of each strain was determined by muhilocus sequence typing (MLST). The genotypes of staphylococcal cassette chromosome mec(SCCmec) of the CA-MRSA isolates were confirmed by multiplex PCR. Results Among 65 isolates of CA-MRSA, the positive rate of PVL genes was 47.69%(31／65). The most common MLST type was ST59 (n=22, 33.84%), followed by ST88 (n=15, 23.07%). Three SCCmec types were found. The most common type was SCCmecIV (49.23%, 32/65), followed by SCCmecⅡ (32.30%, 21/65) and SCCmecV (8.46%, 12/65). Conclusion The PVL gene-positive rate of CA-MRSA isolates in our hospitals is at a relatively high level. SCCmec type IV and SCCmec type V could spread among hospitals and cause a small scale epidemic. Their phenotypes have a variety of ST types.
