OBJECTIVETo investigate the application of three-dimensional CT(3D-CT) in the treatment of oblique facial clefts with mandibular outer cortex, including the surgical design and results assessment.
METHODSFrom Jan. 2003 to Dec. 2013, 22 cases with oblique facial cleft, who underwent mandibular outer cortex onlay bone graft were retrospectively studied. 3D images from CT data were reconstructed before operation for design. Then the mandibular outer cortex onlay bone transplant was performed to reconstruct the bone defect and cleft. 3D CT was performed 5-10 days postoperatively and 6- 12 months postoperatively to assess the facial symmetry.
RESULTSAccording to the results of CT measurement, the average volume of the orbital bone defects on the affected side decreased by(64. 6 ± 14. 4)% 5 to 10 days after operation. The average volume of the maxillary and zygomatic bone defects on the affected side decreased by(71.4 ± 15.7)% after surgery. After 6 to 12 months,the average recovery of the mandibular donor site was (57. 9 ± 13. 9)% of the removed mandibular outer cortex. The average absorption of grafted bones was(24.7 ± 25.6 )%. The average height difference between the centre of pupils on both sides before surgery was(3.76 ± 1.27) mm,which decreased to( 1. 15 ± 1.00) mm 5 to 10 days after surgery(P =0. 000) , and( 1.35 ± 1. 13) mm 6 to 12 months after surgery(P = 0. 003). The relapse may be caused by the absorption of the grafted bones.
CONCLUSIONS3D-CT can be used for preoperative design and postoperative assessment in the treatment of oblique facial cleft with mandibular outer cortex.

Objective To investigate the clinical characteristics of childhood purulent meningitis (PM)and the risk factors for its adverse outcome.Methods One hundred and nine children with PM were retrospective ana-lyzed,who were admitted to pediatric department in Xijing Hospital of the Fourth Military Medical University from Ja-nuary 2008 to July 201 6.They were divided into 5 age groups,the clinical features were compared among the different age groups.According to Glasgow prognostic score,all cases were then divided into 2 groups,the favorable outcome group and the adverse outcome group.All factors including normal information,disease history,clinical manifestations and laboratory examinations were compared between 2 groups.Results There were 72.5% (79 /1 09 cases)of the pa-tients younger than 3 years old.PMwas prone to spring and winter,and most children with PMhad preceding infection. The major clinical manifestations of PM were fever,convulsions and intracranial hypertension.The clinical manifesta-tions of PMwere different in different age groups,and convulsions were more commonly seen in less than 3 years old children,while headache,vomiting and meningeal stimulation had higher proportion in more than 3 years old children. The single factor analysis showed that there were repeated convulsions after admission (≥3 times),the cerebrospinal fluid (CSF)glucose(≤1 .5 mmol/L),CSF protein(≥1 g/L),CSF /blood glucose ratio and complications were signifi-cantly different between 2 groups(all P <0.05).While gender,age distribution,fever,intracranial hypertension,coma, limb movement disorder,meningeal stimulation,CSF cell count >500 ×1 06 /L,blood and CSF cultivate positive rate, co -infection,brain CT/MRI abnormality,electroencephalogram abnormality,treatment and duration of seizure more than 5 minutes were not significantly different(all P >0.05).Multivariate analysis showed that there were repeated convulsions after admission (≥3 times)(OR =27.84,P =0.048),CSF protein(≥1 g/L)(OR =28.44,P =0.027) and low CSF /blood glucose ratio (OR =22.1 5,P =0.041 )were independent risk factors for poor prognosis of PM. Conclusion PMhappens mostly in infantile period,with different clinical manifestations at different ages.The inde-pendent risk factors for poor prognosis were repeated convulsions after admission (≥3 times),CSF protein(≥1 g/L) and low CSF /blood glucose ratio.It indicates that if the high risk factors could be identified early,and then intervened immediately and followed up timely,it will be beneficial to improve the long -term prognosis.

Objective: To investigate the potential role and our experience of perioperative nutritional support in the management of patients with Crohn's disease (CD).Methods: 150 CD patients (male to female=101:49) performed with operation and from the year 1997 to 2007 were analyzed retrospectively. Their nutritional index, Crohn's Disease Activity Index (CDAI), sites of lesion, causes and procedures of operation, usage of nutritional support pre-operatively and post-operatively, and operation-related complications were all recorded.Results: Malnutrition, as indicated as BMI<18.5 kg/m2 or decrease of body weight>10% over the recent 3 months,occurred in 130 patients (88.67%)on admission.After aggressive nutritional support,patients' nutritional index, such as blood haemoglobin, serum albumin, pre-albumin, transferrin and lymphocytes counts all increased significantly pre-operatively and on discharge compared with on admission, while the change of BMI was not significant. For 53 patients receiving home enteral nutrition after discharge, their BMI increased significantly on last follow-up compared with on admission (19.24 vs 17.64, P<0.001). Operation-related complications occurred in 14 patients (9.33%), and two of them died due to severe intra-abdominal infections. Two patients with severe retroperitoneal infection on admission were successfully treated using the damage-control surgery.Conclusion: Malnutrition is a common complication in CD patients receiving surgery, and aggressive perioperative nutritional support may have a positive effect on the morbidity and mortality in such patients. Long-term maintenance therapy with enteral nutrition may delay the postoperative recurrence of the Crohn's disease and should be considered. For critically ill CD, damage-control surgery may get a better outcome than conventional treatment procedures.
