To evaluate the method and effectiveness of anterior focus clearance with autograft bone fusion and internal fixation in treating of adjacent multivertebral tuberculosis in one-stage. Methods Between March 2007 and September 2009, 8 cases of thoracic vertebra tuberculosis were treated. Of 8 cases, 6 were male and 2 were female, aged 32 years on average (range, 20-42 years). The disease duration ranged from 8 to 14 months (mean, 10.2 months). Affected vertebrae included thoracic vertebrae in 35 cases and lumbar vertebrae in 11 cases; 5 vertebrae were involved in 4 cases, 6 vertebrae in 3 cases, and 8 vertebrae in 1 case. According to Frankel classification, there were 2 cases of grade C, 4 cases of grade D, and 2 cases of grade E. All patients had different kyphosis with the Cobb angle of (25.1 ± 6.6)°. All patients received antituberculous therapy 4-6 weeks preoperatively; after complete clearance lesions, autograft bone fusion and internal fixation were performed, and then antituberculous therapy was given for 18 months. Results All incisions healed by first intention. Eight patients were followed up 18-48 months (mean, 29 months). According to JIN Dadi et al. criterion, 7 cases recovered after first operation, 1 case of relapsed tuberculosis with sious was cured after re-focus clearance. The Cobb angle was (19.5 ± 4.2)° at 7 days after operation and was (22.3 ± 3.6)° at last follow-up, showing significant differences when compared with the preoperative value (P lt; 0.05). The nerve function of all cases were classified as Frankel grade E. CT scan showed bone graft fusion at 6-8 months after operation. No loosening or displacement of grafted bone and internal fixation occurred during follow-up. Conclusion The treatment of adjacent multivertebral tuberculosis by anterior focus clearance, intervertebral autograft, and internal fixation in one-stage is effective. Anterior bone fusion and internal fixation in one-stage can correct kyphosis effectively and rebuild spinal stabil ity, so it is a good choice for surgical treatment of adjacent multivertebral tuberculosis.
Objective To evaluate the diagnostic value of all diagnostic tests for detecting armazide resistance in mycobacterium tuberculosis. Methods We searched PUBMED, EMBASE, CBM, CSJD and CJFD. QUADAS items were used to evaluate the quality of included studies. Meta-disc software was used to handle data from included studies. Results Twelve studies were included. Meta-analyses showed that the summary sensitivity and summary specificity of nitrate reductase assay were 92% and 99%, and those of BACTEC MGIT 960 system were 93% and 96%, respectively. The SROC of nitrate reductase assay and BACTEC MGIT 960 system were 0.9836 and 0.9862, respectively. Conclusion We recommend that proportion method can be replaced by nitrate reductase assay as a screening test for detecting armazide resistance in mycobacterium tuberculosis, and BACTEC 460 can be replaced by BACTEC MGIT 960 system as a final diagnostic test for detecting armazide resistance in mycobacterium tuberculosis.
Objective To explore the effectiveness and related issues in the treatment of multiple segments of thoracolumbar tuberculosis through posterior unilateral debridement with bone graft and internal fixation. Methods The clinical data of 29 patients with multiple segments of thoracolumbar tuberculosis who met the selection criteria were retrospective analyzed between January 2012 and July 2015. There were 17 males and 12 females, with age of 21-62 years (mean, 37.4 years). Lesions contained 3-8 vertebral segments, including 3 segments in 6 cases, 4-6 segments in 17 cases, and 7-8 segments in 6 cases. The center lesions located at thoracic spine in 8 cases, lumbar spine in 10 cases, and thoracolumbar segment in 6 cases, and thoracic lumbar skip lesions in 5 cases. The complications included vertebral abscess in 7 cases, psoas major abscess in 6 cases, sacral spine muscle abscess in 7 cases, iliac fossa and the buttocks abscess in 1 case, spinal canal abscess in 2 cases. Preoperative neurological function was assessed according to the American Spinal Injury Association (ASIA) classification: 1 case of grade B, 3 cases of grade C, 8 cases of grade D, and 17 cases of grade E. The disease duration was 6-48 months (mean, 19.3 months). All the patients were treated with posterior unilateral transpedicular or transarticular debridement with bone graft fusion and internal fixation under general anesthesia. Pre- and post-operative visual analogue scale (VAS) score, Oswestry disability index (ODI), and sagittal Cobb angle were recorded and compared. Bridwell classification standard was used to evaluate bone graft fusion. According to the number and the center of the lesion, the necessity to placement of titanium mesh cage was analyzed. Results All the patients were followed up 18-30 months (mean, 24 months). Cerebrospinal fluid leakage occurred in 3 cases, intercostal neuralgia in 2 cases, wound unhealed and fistula formation in 1 case, and ofiliac fossa abscess recurred in 1 case, and all recovered after symptomatic treatment. During follow-up, no fracture or loosing of internal fixation was found and all the lesions were cured at last follow-up. According to Bridwell classification standard, bone graft achieved bony fusion during 4-9 months after operation. The VAS score, ODI, and Cobb angle at immediate after operation and at last follow-up were significantly improved when compared with preoperative ones (P<0.05). At last follow-up, the neural function of all patients improved significantly when compared with preoperative one (Z= –3.101, P=0.002). The ratio of no placement of titanium mesh cage was significantly higher in patients with more than 6 lesion segments (6/6, 100%) than in patients with less than 6 lesion segments (4/23, 17.4%) (χ2=14.374, P=0.000). And the ratio of placement of titanium mesh cage was not significantly different between the patients with the different locations of center focus (χ2=0.294, P=0.863). Conclusion For treating multiple segments of thoracolumbar tuberculosis, the method of posterior unilateral debridement with bone graft and internal fixation can decrease the damage of posterior spinal structures and surgical trauma.
Objective To investigate and analyze the epidemic characteristics and factors of pulmonary tuberculosis (PTB) to provide foundation and make prevention and treatment policy. Methods Statistical analysis was conducted to analyze the current existing PTB prevention and control data in the Center for Disease Control and Prevention of Zhushan County and corresponding prevention and treatment policy was proposed. Results Since 1997 when PTB was included into B infectious diseases in Zhushan County, 4 431 cases of PTB had been reported by the end of 2009. Annual reported incidence rate was 74.73 per 100 000 and the disease was found in 17 towns. All seasons witnessed the incidence but winter and summer had more sufferer. The youngest patient was 4 months whereas the oldest was 86 years old. The majority of the patients were from 20 to 59 years old, peasants were the main patients, and the incidence of male was higher than that of female. The use of chemotherapy resulted in a significant decline of PTB death rate. Poor immunity of elder group, population flow caused by poverty, low detection rate of patients and AIDS were the major causes to PTB epidemic. A lack of prevention and treatment in the grassroots hospital and difficulty to fully implement the Directly Observed Treatment, Short-course (DOTS) strategy in remote areas were also bottlenecks to PTB control process. Conclusion The followings should be performed to improve the quality of DOTS strategy implementation: strengthen the government’s commitment, provide policy and funding safeguard, conduct health education and health promotion widely, reinforce management according to the law, fully implement the DOTS strategy, and fortify the prevention and control construction.
ObjectiveTo investigate the short-term effectiveness of one-stage radical debridement and total hip arthroplasty (THA) in the treatment of active tuberculosis of the hip. MethodsBetween January 2006 and June 2011,one-stage radical debridement and THA were performed on 12 cases (12 hips) of active tuberculosis of the hip.There were 7 males and 5 females,aged 18-60 years (mean,46.3 years).The disease duration ranged from 6 to 24 months (mean,10.5 months).According to Babhulkar and Pande staging criteria,5 cases were at stage Ⅲ and 7 cases were at stage IV.One case had sinus,and 2 cases had previous pulmonary tuberculosis.Preoperative hip range of motion was (35.83±9.25)°; hip Harris score was 36.83±6.44.Erythrocyte sedimentation rate (ESR) was 45-90 mm/1 h (mean,62.4 mm/1h); C-reactive protein (CRP) was 19-50 mg/L (mean,33.6 mg/L).Perioperatively all the patients accepted the regular anti-tuberculous medication. ResultsThe results of histopathological examination and PCR detection were positive for tuberculosis bacillus.Postoperatively the incisions healed primarily.All the patients were followed up 25-60 months (mean,40.8 months).The ESR and CRP returned to normal level with no liver injury.Tuberculosis recurrence occurred in 1 patient at 4 months after operation,which was cured after revision.X-ray film showed no prosthesis shift,prosthesis loosening,or sinus tract.At 18-24 months after operation,the bilateral sides had the same bone density,which was similar to that at the final follow-up.Hip range of motion was significantly improved to (107.08±13.56)° (t=14.571,P=0.000).Hip Harris score was significantly increased to 88.00±10.78 (t=16.750,P=0.000). ConclusionA combination of one-stage radical debridement and THA is a safe method to treat active tuberculosis of the hip,which can relief symptoms and improve hip function,with low recurrence and satisfactory short-term effectiveness.
ObjectiveTo compare Crohn disease(CD) with intestinal tuberculosis(ITB) in clinical and multislice CT(MSCT) features that may be helpful for the differential diagnosis. MethodsThirty-eight patients with CD and 13 with ITB proved surgically and pathologically were recruited for this study. The clinical symptoms, laboratory, and MSCT findings in these patients were retrospectively analyzed. ResultsThe MSCT changes helpful in distinguishing CD from ITB included:①CD presented symmetrical intestinal wall thickening in most cases, while ITB were asymmetric (P < 0.05).②The irregular stricture was more common usually shown in CD groups, while coaxial in ITB(P < 0.05).③The lymphadenopathy with obvious enhancement and tortuously mesenteric vessels were frequently found in ITB group (P < 0.05). The clinical features of CD including abdominal pain, diarrhea, fever, anemia, hematochezia, weight loss, and intestinal complications were similar with ITB, and similar results were detected in the laboratory examination including the acceleration of erythrocyte sedimentation rate, postive C-reactive protein, and the reduction of albumin. The feature of hematochezia was more common in CD than in ITB, while concomitant pulmonary tuberculosis was more revealed in ITB(P < 0.05). ConclusionsThe MSCT findings of CD and ITB are characteristic. Combined with the similar clinical and laboratory features, the features of MSCT maybe helpful for definitive diagnosis.
ObjectiveTo systematically review the diagnosis value of T cell ELISA Spot (T-SOPT.TB) in for bacterium negative pulmonary tuberculosis in Chinese. MethodsWe electronically searched databases including PubMed, CBM, CNKI, WanFang Data and VIP from inception to December 31st, 2015 to collect studies about T-SPOT.TB in diagnosis bacterium negative pulmonary tuberculosis in Chinese. Two researchers independently screened literatures, extracted data, and assessed the risk of bias of included studies, and then meta-analysis was performed by using Stata 12.1 and Meta-DiSc 1.4 software. ResultsA total of 11 studies including 1 413 patients and 1 256 controls were included. The results of meta-analysis showed that the pooled sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, diagnosis odds ratio and area under SROC curve for T-SPOT.TB diagnosis bacterium negative pulmonary tuberculosis was 83% (95%CI 0.81 to 0.85), 86% (95%CI 0.84 to 0.88), 5.73 (95%CI 4.99 to 6.59), 0.20 (95%CI 0.18 to 0.23), 31.09 (95%CI 25.11 to 38.49), and 0.92, respectively. ConclusionAs a rapid and accurate method for diagnosis of bacterium negative pulmonary tuberculosis, T-SPOT.TB has a high diagnostic efficiency for bacterium negative pulmonary tuberculosis in Chinese.
ObjectiveTo evaluate the expression level and diagnostic value of lnc-PAPSS2-2 (lnc-PA) in peripheral blood of active pulmonary tuberculosis (PTB) patients.MethodsFrom January 2011 to January 2018, 798 patients with active PTB and 1 650 healthy people undergoing health examination in West China Hospital of Sichuan University and their electronic health records (EHR) were collected. Peripheral blood lnc-PA levels were quantified by quantitative real-time polymerase chain reaction method. The data of lnc-PA and EHR were modeled using nomogram, and the receiver operating characteristic (ROC) curves of lnc-PA, EHR and the combination of lnc-PA and EHR were compared to evaluate the diagnostic value of lnc-PA for active PTB.ResultsThe level of lnc-PA was lower in active PTB patients than that in healthy controls (P<0.001). The areas under ROC curve of lnc-PA, EHR and their combination were 0.619, 0.962, and 0.964 in the training set and 0.626, 0.950, and 0.950 in the validation set, respectively.ConclusionThe diagnostic ability of lnc-PA is poor and that of EHR is good, which indicates that the clinical value of lnc-PA as a biomarker of active PTB remains to be further explored.
Ferroptosis is a unique way of cell death discovered in recent years, which involves the lethal process of iron ion accumulation and lipid peroxidation, which is obviously different from the traditional cell death pathway such as apoptosis and necrosis. For a long time, tuberculosis has been a major infectious disease in the field of global public health, which brings a serious burden to the society because of its high morbidity and mortality. The emergence of drug resistance aggravates the difficulty of treating tuberculosis, and new treatment strategies and drug targets are urgently needed. Combined with the latest research progress at home and abroad, This article will discuss the molecular mechanism of ferroptosis and pulmonary tuberculosis and the relationship between signal pathways, biomarkers and related genes, in order to provide a new perspective for the diagnosis and treatment of pulmonary tuberculosis.
Objective To evaluate the diagnosis value of purified protein derivative (PPD) antibody tests in childhood tuberculosis. Methods We reviewed 126 cases of hospitalization children tested body fluid PPD antibody by Enzyme-Linked Immunosorbent Assay (ELISA). Twenty-two them were diagnosed with tuberculosis. We determined the sensitivity, specificity, diagnostic likelihood ratio, positive prognostic value, negative prognostic value, post-test probability, respectively. Results The following accuracy statistics for the PPD body liquid antibody tests in this study: sensitivity, 45.45%; specificity, 91.35%; diagnostic likelihood ratio positive, 5.25; diagnostic likelihood ratio negative, 0.597; positive predictive value, 52.63%; negative predictive value, 88.79% and post-test probability, 48.09% in 15% of prevalence. Conclusion This study shows that body fluid PPD tests have limited value for diagnosis of tuberculosis in pediatric tuberculosis. Clinic physicians should be wary of the positive results of body fluid PPD antibody tests. The value of diagnosis is related to prevalence of tuberculosis in the specific hospital.
