ObjectiveTo explore the clinical application and effectiveness of antibiotic-loaded cement spacer combined with free fibular graft in the staged treatment of infectious long bone defect in the lower extremity.
MethodsA retrospective analysis was made on the clinical data from 12 patients with infectious long bone defect in the lower extremity between June 2010 and June 2012. Of the 12 cases, there were 9 males and 3 females with an average age of 33 years (range, 19-46 years), including 3 cases of femoral shaft bone defect, 7 cases of tibial shaft bone defect, and 2 cases of metatarsal bone defect. The causes were traffic accident injury in 7 cases, crashing injury in 3 cases, and machine extrusion injury in 2 cases. The length of bone defect ranged from 6 to 14 cm (mean, 8 cm). The soft tissue defect area ranged from 5.0 cm×3.0 cm to 8.0 cm×4.0 cm companied with tibial shaft and metatarsal bone defect in 9 cases. The sinus formed in 3 femoral shaft bone defects. The time between injury and operation was 1-4 months (mean, 2 months). At first stage, antibiotic-loaded cement spacer was placed in the bone defect after debridement and the flaps were used to repair soft tissue defect in 9 cases; at second stage (6 weeks after the first stage), defect was repaired with free fibular graft (7-22 cm in length, 14 cm on average) after antibiotic-loaded cement spacer removal. The area of the cutaneous fibular flap ranged from 6.0 cm×4.0 cm to 10.0 cm×5.0 cm in 10 cases.
ResultsAll wounds healed by first intention, and the healing time was 12-18 days, 14 days on average. Twelve cases were followed up 12-36 months (mean, 17 months). Bone healing time ranged from 4 to 6 months (5.5 months on average). The cutaneous fibular flap had good appearance. The function at donor site was satisfactory; no dysfunction of the ankle joint or tibial stress fracture occurred after operation. The mean Enneking score was 25 (range, 20-28) at last follow-up.
ConclusionInfection can be well controlled with the antibiotic-loaded cement spacer during first stage operation, and free fibular graft can increase the bone defect healing rate at second stage. Staged treatment is an optimal choice to treat infectious long bone defect in the lower extremity.

Methods: Five hundred perioperative records of patients with incision Ⅰ were randomly chosen and surveyed in 2009. A questionnaire for prophylactic use of antimicrobial was designed. The indication of antimicrobial use, the species, combination, timing and drug duration were analyzed. Results: Our of 500, 495 used antimicrobial and 80 were unreasonable; 540 kinds of antimicrobial were used, included cephalosporin 453 cases (83.89%), penicillin class (including plus enzyme inhibitors) in 26 cases (4.81%), quinolone 44 cases (8.15%). Cefazolin sodium (178 patients, 32.96%) ranked first, second was cefazolin sodium (151, 27.96%). Conclusion: Perioperative use of antimicrobial prophylaxis in patients with incision Ⅰ is reasonable, but standardization management should be strengthened in the indication, species, and duration.
Objective To determine whether antibiotic prophylaxis can reduce the risk of postoperative bacteriuria in men undergoing transurethral resection of prostate (TURP) who have sterile preoperative urine. Method MEDLINE, EMBASE and Cochrane Library were searched for RCTs comparing antibiotic prophylaxis and placebo/blank controls for men undergoing TURP with preoperative sterile urine. The search strategy was established according to the Cochrane Prostatic Diseases and Urologic Cancers Group search strategy. Data was extracted by two reviewers using the designed extraction form. RevMan were used for data management and analysis. Results Fifty three relevant trials were searched, of which 27 trials were included and 26 were excluded. Antibiotic prophylaxis significantly decreased the rate of post-TURP bacteriuria.The pooled relative risk (RR) and 95% confidence interval were 0.36 (0.28, 0.46). Conclusions Prophylactic antibiotics could significantly decrease the incidence of post-TURP bacteriuria. Further comparative RCTs and cost-effective should be performed analysis to establish the optimal antibiotic regimes for the benefit of patients undergoing TURP.
Objective
To evaluate systematically the effect of antibiotic treatment on ventilator-associated tracheobronchitis (VAT).
Methods
Pubmed,Web of Science,OVID SP (ACP Journal Club,Cochrane Central Register of Contralled Trials,Embase,Medline),as well as China National Knowledge Infrastructure,China Science and Technology Journal Database,and Wanfang Data were searched for literatures about antibiotic treatment on VAT.The search deadline was March 2016.Meta-analysis was conducted with RevMan 5.3 software.
Results
A total of 6 studies with 769 patients were included.Among 769 patients,432 patients were treated by antibiotics,and 337 patients in control group were treated without antibiotics.Meta-analysis showed antibiotics treatment significantly reduced incidence of ventilator-associated pneumonia compared with control group [OR=0.27,95%CI (0.17,0.43),P<0.05],and shortened length of ICU stay [MD -1.51,95%CI(-2.04,-0.98),P<0.00001] .There were no significant difference in duration of mechanical ventilation [MD -2.52,95%CI (-6.85,1.81),P=0.25],mortality [OR=0.41,95%CI(0.15,1.14),P=0.09],or drug-resistant bacteria production [OR=0.62,95%CI(0.17,2.19),P>0.05].
Conclusions
Antibiotic treatment can reduce incidence of ventilator-associated pneumonia in patients with VAT.Further more high quality randomized controlled trials are needed to assess the effect of antibiotic treatment on VAT.
Objective To investigate the value of procalcitonin-guided treatment on antibiotic use in severe acute exacerbations of asthma. Methods From April 2008 to December 2010, a total of 77 patients with severe acute exacerbations of asthma were randomly assigned into a PCT group ( n =38) and a control group ( n=39) . The serum concentration of procalcitonin ( PCT) were measured in all patients. On the base of similar routine treatment, the control group received antibiotics based on the physician’s decision.Meanwhile the PCT group were treated with antibiotics according to serum PCT levels: antibiotic treatment was applied with PCT level ≥0. 25ng/mL and was discontinoued with PCT level lt; 0. 25ng/mL. Length of hospitalization, duration of antibiotics, cost of antibiotics, clinical efficacy were observed. Results The duration of antibiotics use in the PCT group [ 7 ( 5 ～11) d] was shorter than that in the control group [ 11( 7 ～16) d] ( Z = - 2. 26, P = 0. 025) , and the cost of antibiotics in the PCT group [ 2125( 1560 ～4347) yuan] was lower than that in the control group [ 3588 ( 2677 ～5280) yuan] ( Z = - 2. 01, P =0. 033) . The clinical efficacy and length of hospitalization were similar in two groups ( P gt; 0. 05) .Conclusion PCT guidance can reduce antibiotic duration and antibiotic cost in treatment of acute severe exacerbations of asthma.
Objective To systematically evaluate the clinical effect and safety of Bifidobacterium tetravaccine tablets in the treatment of antibiotic associated diarrhea (ADD) in infants in China. Methods Randomized controlled trials (RCTs) of treatment of AAD by Bifidobacterium tetravaccine in infants were searched by computer from China Knowledge Resource Integrated Database, VIP and Wanfang Data from their inception to November 2016. Meta-analysis of the data was carried out by RevMan 5.3 software. Results Twelve RCTs were chosen, which included 1 761 infant patients. The Meta analysis showed that the effects of treatment of ADD were significantly superior to those of the control group [OR=5.74, 95%CI (4.14, 7.96),P<0.000 01]. Among the 12 RCTs, 8 had no adverse reactions, while the rest4 articles did not mention adverse reactions. Conclusions Based on the present clinical evidences, treatment of ADD by Bifidobacterium tetravaccine in infants is effective and safe. But due to the small number and different quality of RCTs, this conclusion still needs to be confirmed by large sample, multicenter, and high-quality clinical RCTs.
ObjectiveTo evaluate the value of serum procalcitonin (PCT) level after conventional intravenous antibiotic treatment to predict the risk of re-exacerbation, and vertify the feasiblity of an additional course of oral antibiotics after discharge to reduce the risk of re-exacerbation.
MethodsThe patients who hospitalized in West China Hospital from October 2012 to October 2013 because of infectious acute exacerbation of chronic obstructive pulmonary disease (AECOPD) were recruited. The concentrations of PCT and C-reactive protein (CRP), the number of white blood cell (WBC) and neutrophil percentage at the end of intravenous antibiotic therapy were recorded. The information about additional course of antibiotics was collected according to the medical instruction and visit. The subjects were followed up for 1 year.The time to the first re-exacerbation and frequencies of exacerbations were recorded. The Cox regression model was used to estimate the hazard rations (HR).
ResultsOne hundred and thirty-eight eligible patients were included totally. The HRs in PCT≥0.11μg/L and neutrophil percentage≥70% were 1.462 (P=0.035) and 1.673 (P=0.005) respectively, suggesting higher risk of re-exacerbation. There was no relationship of CRP (P=0.330) or WBC (P=0.432) with the risk of re-exacerbation. Generally an additional course of antibiotics had no effects on re-exacerbation (P=0.231) but this therapy could reduce the risk of re-exacerbation in high PCT level group (HR=2.29, P=0.004).
ConclusionsSerum PCT concentrations and neutrophil percentage after conventional intravenous antibiotic treatment can predict the risk of re-exacerbations in the future. An additional course of antibiotics in the patients with high PCT level can reduce the risk of re-exacerbation.
