Abstract Dual-blade plate is widely used in reconstruction of anterior stability of spine. Two hundred and ninety-eight cases were followed up since 1984. Among them, 181 cases were fractureof thoracolumbar spine; 63 cases were tuberculosis of thoracolumbar spine; 43 cases were tumor of thoracolumbar spine; 5 cases were spondylisthesis of lumbar spine; 2 cases were ankylosing spondylitis accompanied with gibbosity; 2 cases were adolescent vertebral epiphysis; I case was hemivertebra; I case was dysplasia of the first lumbar vertebra acompanied with gibbosity. Most cases were successful following operation, but in some cases, the results were unsuccessful, mainly due to the position of the dualblade plate in the vertebral body was not satisfactory. The mistakes most commonly occurred were one or two blades, or a part of the blade going into the intervertebral space, and less commonly seen was deviation of the dual -blade plate from itscorrect orientation or a little side-bent of the blade. Split of the vertebra and fall off of the dual-blade plate were happened in few cases. The causeswere analyzed and ways of prevention were provided in this article.
ObjectiveTo observe the ocular manifestations of presumed ocular tuberculosis in patients with pulmonary tuberculosis.
MethodsOne hundred and fifty nine patients with pulmonary tuberculosis received examinations of visual acuity, slit lamp microscopy and indirect ophthalmoscopy. Those patients with retinochoroidal inflammatory lesions, retinal hemorrhages or detachments underwent fundus fluorescein angiography (FFA) and optical coherence tomography (OCT) to determine whether the presumed ocular tuberculosis was involved. There were 9 patients (16 eyes, 5.67%) of presumed ocular tuberculosis, including 5 males and 4 females. The age was ranged from 19 to 64 years old, with an average of 35.12 years. Seven patients were affected bilaterally and 2 patients affected unilaterally. There were 8 patients (15 eyes, 93.75%) with uveitis and 1 patient (1 eye, 6.25%) with central retinal vein occlusion (CRVO). The blood laboratory tests were negative in all cases.
ResultsThe corrected vision was from light sensation to 0.15 in 6 uveitis eyes, 0.8 to 1.0 in 10 eyes. The anterior segment change was found in 10 eyes, which including granulomatous uveitis (8 eyes) and non-granulomatous uveitis (2 eyes). Granulomatous uveitis eyes had iris nodules, posterior synechia of the iris and mutton-fat keratic precipitates (KP). Non-granulomatous uveitis eyes had KP only. Choroidal tubercles were found in 7 eyes in which 3-7 off-white lesions of varying sizes were found with local retinal detachment. FFA revealed hypo-fluorescence with obscure boundary in arterial phase and arterial and venous phase, and hyper-fluorescence with obscure boundary in later phase. OCT showed retinal pigment epithelium uplift. There was 1 eye with CRVO, which had punctate, splinter and linear hemorrhage, white lesions in some hemorrhagic focus.
ConclusionThe presumed ocular tuberculosis eyes showed mainly granulomatous inflammation and multiple choroid tubercles, and CRVO sometime.
ObjectiveTo investigate the diagnostic value of internal medicine thoracoscope combined with pleural GeneXpert MTB/RIF for tuberculous pleurisy.MethodsEighty patients with tuberculous pleurisy admitted to hospital with pleural effusion were treated as tuberculous pleurisy group, and 20 patients with clinical diagnosis of malignant pleural effusion were used as control group. After admission to the hospital, the pre-operative examination of internal medicine thoracoscope were analyzed. All patients were extracted pleural effusion with thoracic puncture in order to send pleural tuberculosis smear and culture. Patients who had no contraindications were arranged internal medicine thoracoscope to get pleural effusion which will be sent to GeneXpert MTB/RIF and pathological tissue biopsy.ResultsIn the tuberculous pleurisy group, nine patients were positive in pleural tuberculous smear, and the positive rate was 11.3%; 4 patients were positive in pleural tuberculous culture, and the positive rate was 5.0%; 75 patients were diagnosed with pathological biopsy, and the positive rate was 93.8%; 69 patients were positive with pleural GeneXpert MTB/RIF, and the positive rate was 86.3%. The positive rate of internal medicine thoracoscopic pleural biopsy combined with pleural GeneXpert MTB/RIF could reached 96.3%. The pleural GeneXpert MTB/RIF lifampin resistance gene was positive in 5 patients, 4 of them were positive for tuberculosis culture, and the drug sensitivity results showed rifampicin resistance. In the control group, patients had negative result in pleural effusion tuberculosis smear, tuberculosis culture and the pleural GeneXpert MTB/RIF.ConclusionsThe diagnosis of tuberculous pleurisy by the combination of internal medicine thoracoscope and pleural GeneXpert MTB/RIF has high specificity and sensitivity. The diagnosis of tuberculous pleurisy by the combination of internal medicine thoracoscope and pleural GeneXpert MTB/RIF has high specificity and sensitivity, which has the value of rapid and accurate diagnosis and early guidance of anti-tuberculosis chemotherapy based on the early judgment of whether rifampin resistance exists.
Objective To investigate the value of multislice spiral CT （MSCT） findings in the diagnosis of hepatic tuberculosis. Methods MSCT imaging data, including both plain and contrast-enhanced CT scan, of 14 patients with hepatic tuberculosis confirmed by surgery (5 patients), aspiration biopsy (4 patients), or clinic follow-up (5 patients) were collected for the study. MSCT findings were analyzed with correlation of pathological changes. Results Hepatic tuberculosis was classified into 2 types. ①The parenchymal type (12 patients), which was further divided into 4 subtypes: Miliary subtype (2 patients) showed multiple tiny hypodense dots with faint border and had no enhancement; Nodular subtype (5 patients) showed blurring border on plain CT scan, 2 patients had no enhancement, 2 had peripheral rim-like enhancement, and peripheral rim enhancement mixed with no enhancement in 1 patient; Abscess subtype (4 patients) showed central hypodense area with peripheral zone-like enhancement in 2 patients, or patchy like slight enhancement in 2 patients; Fabric and calcific subtype (1 patient) depicted enplaque calcification. ②The serohepatic type (2 patients) showed thickened hepatic capsule, sub-capsule nodules with slight enhancement, and local subcapsular fluid collection. Other signs included hepatomegaly, tuberculous lymphadenopathy, splenic tuberculosis, and tuberculosis of pancreas, adrenal glands, intestine and thorax. Conclusion MSCT plays an important role in diagnosis of hepatic tuberculosis, by reflecting underlying pathological changes.
Objective To investigate the efficacy of freeze-driedcancellous allograft in the treatment of spinal tuberculosis. Methods From January 1999 to August 2004, there were 31 cases of spinal tuberculosis who underwent surgery. The freeze-dried cancellous allograft was used as grafting material in all the cases.The cancellous allograft was packed in a titanium mesh cage or an artificial vertebrae, and then used as a strut graft anteriorly to implant into the bone defect after the redical debridement, and the instrumentation was done. Results Twenty-three cases were followed up 1.5 years to 5 years (3.7 years on average), and bonyfusion was achieved in 21 cases 6 months later. In 2 cases ceasing antituberculous therapy after 2 months of operation, the local recurrence was obvious. The loosened screw was noticed in one of these two cases, who had tuberculosis in lumbar spine. When antituberculous therapy continued, the bony fusion was observed in these two cases 12 months later. No further position change of the instrument wasnoticed in the patient carrying loosened screw, but the kyphosis of the thoracolumbar spine aggravated. Conclusion Freeze-dried cancellous allograft could be usedin the treatment of spinal tuberculosis. To achieve good results of allograft incorporation and remodeling, the rigid instrumentation should be performed, postoperative antituberculous therapy is also important.
ObjectiveTo understand basic characteristics and clinical features of tuberculosis in Mianyang, Sichuan, and to investigate the risk factors of two case-finding methods for tuberculosis:"passive finding" and "active screening".
MethodsOne-hundred and seventy-five active tuberculosis patients screened by physical examination in 21 villages of Fucheng and Jiangyou from June 2013 to March 2014 were included. Information about basic characteristics and clinical features of tuberculosis was collected using questionnaire, chest X-ray and laboratory examinations. We also applied binary logistic regression to explore the risk factors of finding for tuberculosis.
ResultsIn all 175 tuberculosis patients, 41.71% were over 60 years old and 73.71% were farmers. Productive cough over two weeks was the most common symptom, accountting for 58.29%. 19.63% were sputum smear-positive while 70.87% were PPD-positive. Binary logistic regression analysis demonstrated that tuberculosis history significantly influenced the findings for tuberculosis (OR=15.809,95%CI: 6.708~37.258).
ConclusionsActive tuberculosis patients screened by physical examination in Mianyang, Sichuan were mainly elderly male over 60 years old and farmers, with single pulmonary symptom as the primary clinical feature. The patients with tuberculosis history may be found by "passive finding".
Objective To estimate the proportion of Chongqing TB patients who have access to mobile phones, to describe the utilization practice of those mobile phones, and to learn the general information of those TB patients, so as to provide feasibility basis for further intervention of SMS reminder systems. Methods The stratified cluster sampling method was used and four TB high-risk districts were selected. Both quantitative and qualitative research methods were used to interview the TB patients and suspects who had come to their local TB dispensaries during the past two months. The quantitative data was double entered using EpiData 3.1. The association of mobile phone utilization parameters with key variables was determined using chi-square test and logistic regression analyses. The qualitative data was managed, coded and retrieved using MAXQDA, and analyzed using thematic framework approach. Results Of the patients interviewed by quantitative research, the mobile phone ownership rate was 91.1%; 914 cases (80.4%) of the respondents were able to receive text messages; and most people (81%) held favorable opinions on SMS reminders. The main factors related to mobile phone ownerships and receiving SMS were age, occupation, education level, and place of residence. The male patients, in the age group of 19-49 years old, with education level of high school or higher were more likely to have access to mobile phones. The results from qualitative interview were similar. Conclusion Considering the high access to mobile phones of patients interviewed and patients’ views on SMS reminders, it is feasible to conduct a pilot intervention using SMS as a strategy to improve adherence to TB treatment in Chongqing.
ObjectiveTo discuss clinical characteristics and nursing countermeasure of pregnant/delivery women with tuberculosis.
MethodsFrom January 2012 to December 2013, 52 cases of pregnant women complicated with tuberculosis were included. We offered specific nursing according to the psychological counseling, reasonable administration, diet nursing, fever and prevention of hospital infection on the base of their clinical features, and then analyzed the effect.
ResultsIn 52 patients who had undergone the tuberculosis and obsterrics and gynecology treatment, 4 puerperal patients died of severe pneumonia and multiple organ failure; in 48 gestational patients with tuberculosis, 23 early-middle term patients accept termination of pregnancy, and in 25 middle-late term patients, 3 had full-term natural labor, 4 underwent full-term cesarean section, 5 had premature labor, and 13 continued the pregnacy. Sixteen neonatus (including 4 given at the other hospitals) had normal results of physical examination without any deformity, in whom 5 had low body weight (body weight less than 2500 g), with negative results of tuberculin test and the result of 3-moth follow-up was normal. Three months after the anti-tuberculosis treatment, the lesion was obviously absorbed in 25 patients and in 23 patients within half of a year. No patients had hospital infection.
ConclusionNursing care of pregnant patients with tuberculosis should strengthen the guidance on the patients health education, improve their compliance and self-protection knowledge. Also should strengthen the basic level medical personnel training and improve the ability of early diagnosis of tuberculosis and early treatment to reduce maternal mortality.
Objective To explore the application of peer education in TB prevention at middle schools in Kai County of Chongqing and compare it with traditional education, and to provide theory support for further policy making. Methods Four complete middle schools were randomly selected as the control group, the peer education group, the traditional education group and the combined group of peer education and traditional education, respectively. Effect evaluation was performed one month later (instant evaluation) and six months later (long-term evaluation), respectively, after the intervention period. Results The instant and long-term evaluation showed that the knowledge, attitude and practice scores of the three intervention groups were higher than the scores before intervention or those of the control group (Plt;0.01). Besides, the behavior score of the peer education group had no significant difference between instant and longterm evaluation. All scores in the instant evaluation were higher than those of long-term evaluation both in the peer education group and the traditional education group (Plt;0.01). For the knowledge, attitude and practice scores, there was no significant difference between instant and long-term evaluation in the combined group of peer education and traditional education. Conclusion Compared with the peer education group and the traditional education group, the combined group achieves an enduring effect. There is obvious instant effect in the traditional education group, and peer education has a long-term influence on students’ behavior.
Tuberculosis remains a major public health problem. Genetic epidemiological studies have shown that the differences in host genes partly determine the susceptibility to tuberculosis. The occurrence of tuberculosis is the result of the joint action of Mycobacterium tuberculosis and host gene regulation immune response. The study of susceptibility candidate genes has differences in race, population and region, and the study of susceptibility gene polymorphism still has a long way to go in clinical precision diagnosis and treatment. The study and clinical application of mendelian susceptibility to mycobacterial disease can be used as a classic application of precision medical treatment in tuberculosis; although it is a rare case, this model is worthy of reference.
