ABSTRACT

Objective:To summarize the clinical characteristics and prognosis of acute hyperextension spinal cord injury (SCI) in children, and to provide some recommendations for the treatment and prevention of this disease.Methods:Reviewed the data of children of SCI after sustained or repeated hyperextension of the spine at Wuhan Union Hospital and Wuhan Children's Hospital from September 2010 to September 2020. According to the American Spinal Injury Association impairment scale (AIS grade), the patients were divided into complete SCI group and incomplete SCI group. The age, symptoms and evolution after injury, neurological level of injury, imaging data, laboratory examination data, prognosis and complications of the two groups were analyzed. Retrospectively summarize the characteristics of this type of injury.Results:Forty-four cases of acute hyperextension SCI in children were included. Their age ranged from 3 to 10 years old, 95% of them were under 8 years old and 95% of them were female. There was no significant difference in age at injury and time of dance training between children with complete SCI and incomplete SCI. Back and leg pain, lower limb weakness or paresthesia, and rapidly progress to complete or incomplete SCI in a short period were typical symptoms. All blood test results anddiagnostic analysis of cerebrospinal fluid were unremarkable or negative. There was no fracture or dislocation in the whole spine. Magnetic resonance imaging showed a longitudinally extended intramedullary high-intensity signal in the thoracolumbar spinal cord. Complete SCI accounted for 60% of all cases, and the prognosis was poor with spinal cord atrophy and various complications.Conclusion:Children younger than 10 years old after sustained or repeated hyperextension of the spine may suffer acute hyperextension SCI. Children with complete SCI have poor prognosis and serious complications. Therefore, prevention of this type of injury is the best strategy.

ABSTRACT

Objective:To explore the effects of endoscopic reprocessing on disinfection and its influential factors under the coronavirus disease 2019 (COVID-19) pandemic.Methods:A total of 450 endoscopes cleaned and disinfected according to Technical Specifications for Cleaning and Disinfection of Endoscopes from November 2019 to January 2020, and 450 endoscopes cleaned and disinfected according to The recommended procedure for cleaning and disinfection of gastrointestinal endoscopes during COVID-19 epidemic by Chinese Society of Digestive Endoscopology from February to April 2020 in the Second Affiliated Hospital of Chongqing Medical University were enrolled in the control group and observation group respectively by random number method. Both the control group and the observation group contained 200 gastroscopes, 200 enteroscopes and 50 ultrasound endoscopes. ATP fluorescence detection method and pour plate technique were used to evaluate the disinfection effect of endoscopes. Single factor analysis and multiple logistic regression were used to analyze the risk factors for unqualified sterilization after endoscopic reprocessing. Results:The disinfection pass rates of gastroscopes, enteroscopes and ultrasound endoscopes in the observation group were not significantly different compared with those of the control group ( P>0.05). The sterilization pass rates and ATP test pass rates of gastroscopes, enteroscopes and ultrasound endoscopes in the observation group were significantly higher than those in the control group (all P<0.05). Multivariate logistic regression analysis showed that non-strict implementation of endoscopic reprocessing ( OR=7.96, 95% CI: 4.55-22.84, P<0.001), non-standard operation ( OR=2.26, 95% CI: 1.24-5.63, P<0.001), insufficient concentration of disinfectant ( OR=5.43, 95% CI: 2.52-9.02, P<0.001), insufficient concentration ratio of multi-enzyme solution ( OR=4.38, 95% CI: 1.95-8.61, P<0.001), non-timely cleaning ( OR=2.86, 95% CI: 1.33-6.42, P<0.001), incomplete cleaning ( OR=3.75, 95% CI: 1.61-7.49, P<0.001) and improper endoscopic preservation ( OR=2.12, 95% CI: 1.36-4.12, P<0.001) were independent risk factors for unqualified sterilization after endoscopic reprocessing. Conclusion:In COVID-19 pandemic, endoscope reprocessing can significantly improve the disinfection effect of endoscopes, worthy of further clinical promotion. The failure to strictly implement the reprocessing procedure is an important factor that may lead to unqualified sterilization.

ABSTRACT

Objective:To explore the feasibility, safety and clinical efficacy of using the self-developed acetabular posterior wall and column integrative anatomical plate to treat various types of posterior wall/column fractures.Methods:Between January 2016 and January 2019, 21 patients involving acetabular posterior wall and/or column were treated with the novel acetabular posterior wall and column integrative plate, the data were collected and retrospectively analyzed. There were 11 males and 10 females, with an average of 48 years old (range, 18-65 years old). According to the classification of AO/OTA, there were 6 simple fractures, 9 comminuted fractures, and 6 associated with joint surface compression of posterior wall; and there were 16 simple acetabular posterior wall fractures and 5 cases associated with acetabular posterior column fractures. Before operation, the CT data of each patient was collected and imported into Mimics software to reconstruct and print a 3D model of pelvis and injured and mirrored side to simulate operation. All patients were treated with a single Kocher-Langenbeck approach for posterior acetabular fractures, and fixed with the novel integrated anatomical plate after satisfactory reduction was achieved. Matta score was used to evaluate the quality of fracture reduction, and the modified Merle D'Aubigné-Postel score was adopted to evaluate functional recovery of hip joint.Results:21 patients involved in this study, the average time of plate insertion after successful reduction was 20 min (range, 15-30 min); the mean time of operation was 180 min (range, 90-300 min); the intraoperative mean bleeding volume was 700 ml (range, 300-1 500 ml). All the incisions healed by level 1 classification, and no incisions infection and sciatic nerve injury occurred. The patients included in the study have been followed up for at least one year and the imaging data was intact, the mean follow-up time was 19 month (range, 12-26 month). The fracture reduction was evaluated according to the Matta score: 16 cases were anatomical reduction, 3 cases were satisfactory reduction, 2 cases were unsatisfactory reduction, the satisfactory rate of reduction was 90.5% (19/21); the modified Merle D'Aubigné-Postel score at 3 month was 13.0±2.2 (range, 9-16), 6 month was 15.8±2.4 (range, 10-18) and last follow up was 17.0±1.8 (range, 13-18), respectively; the difference was statistically significant ( F=15.38, P < 0.001). At the last follow-up, 15 cases were excellent, 3 cases were good and 3 cases were fair, the total excellent and good rate was 85.7% (18/21). One case developed symptoms of sciatic nerve injury after operation, but the symptoms resolved after treating with neurotrophic drug by 6 months. 2 cases developed arthritis related pain after operation, receiving symptomatic treatment with oral painkillers. During the follow-up period, no complications such as plate broken and screw loosen occurred. Conclusion:The use of an integrative anatomical plate for treating posterior wall/column fractures of acetabulum achieved satisfactory fixation and postoperative functional recovery.

ABSTRACT

Objective:To investigate the advantages and disadvantages and clinical effects of integrated acetabular quadrilateral surface buttress plate in the treatment of acetabular both column fractures.Methods:From September 2017 to March 2019, 14 patients with acetabular both column fractures were treated with integrated quadrilateral acetabular buttress plate and were followed up. The clinical data were retrospectively analyzed. There were 10 males and 4 females with an average age of 53.2 years (range, 26-75 years). Fracture classification were both column fractures according to the Letournel-Judet classification system, including 11 cases of combined posterior wall without posterior dislocation. The time from injury to operation was 8-19 days, with an average of 10.3 days. All operations were performed with a supra-ilioinguinal approach. After satisfactory reduction, the integrated acetabular quadrilateral surface buttress plate was used to fix the anterior and posterior column and quadrilateral fractures at the same time. After operation, Matta criteria was used to evaluate the quality of fracture reduction on postoperative images, and modified Merle d'Aubigné-Postel score to evaluate hip joint function.Results:The average operation time was 180 min (range, 120-320 min), and the intraoperative average blood loss was 980 ml (range, 700-1 600 ml). Operations were performed successfully with none intraoperative reshaping conducted, and the plate could fit into the bone surface well. All 14 patients were followed up with an average of 15.6 months (range, 9-20 months). During the follow-up, all fractures healed with an average of 3 months (range, 2.5-5 months). The reduction quality evaluated by the Matta criteria were 7 anatomical, 5 satisfactory, and 2 unsatisfactory, with an excellent and good rate of 85.7% (12/14). The hip joint function at the last follow-up was in accordance with the modified Merle d'Aubigné-Postel score was 12-18 points, with an average of 16.9 points, of which 8 excellent, 4 good, and 2 fair. The excellent and good function rate was 85.7% (12/14). During the operation, 1 patient had a rupture of about 1 cm of the peritoneum during the separation of the spermatic cord, which was immediately sutured and repaired. One patient had obturator nerve paralysis after the operation, without special treatment, and the paralysis symptoms were relieved during the 6th-month follow-up. There were no other operation-related complications.Conclusion:For both-column fractures characterized by central dislocation of the femoral head, the integrated acetabular quadrilateral buttress plate can simultaneously fix the anterior and posterior columns and quadrilateral surface at the same time. Satisfactory reduction and functional outcomes could be achieved by the novel plates.

ABSTRACT

Objective:To introduce a novel anatomical supra-pectineal quadrilateral surface buttress plate, and explore its advantages, disadvantages and clinical efficacy in the treatment of complex acetabular fractures.Methods:Data of eighteen cases of acetabular fractures treated in our department from March 2017 to March 2019were retrospectively analyzed. There were 15 males and 3 females with an average age of 49.6 years (range, 27-62 years). According to the Letournel-Judet’s classification, there were 3 cases of anterior column fractures (involving quadrilateral surface), 2 cases of "T" shaped, 8 of cases anterior column and posterior hemi-transverse (ACPHT) and 5 cases of double columns fractures. The time from injury to operation was 5-14 days (mean, 7 days). Before operation, all patients were taken pelvic anterior-posterior X-ray and CT scan. All patients were adopted supra-ilioinguinal approach and fixed by supra-pectineal quadrilateral surface buttress plate. Surgical time, intraoperative blood loss and postoperative complications were collected. After operations all patients were taken pelvic X-ray in anterior-posterior and Judet position, as well as CT scan. The radiographic quality of reduction was evaluated by Matta criteria and hip functions were evaluated by Matta Modified Merle d’Aubigné-Postel scoring system.Results:The average surgical time was 130 min (range, 100-200 min). The average blood loss was 560 ml (range, 400-900 ml). An additional shaping was unnecessary in 18 patients who were implanted with the anatomical supra-pectineal quadrilateral surface buttress plate and all patients were operated successfully. All patients were followed up for an average time of 9 months (range, 6-15 months). The quality of fracture reduction was evaluated according to Matta standard, of which there were 11 cases excellent, 4 cases good, and 3 cases poor, with an excellent rate of 83.3% (15/18). At the latest follow-up, the function of the hip joint was evaluated according to the Matta Modified Merle d’Aubigné-Postel scoring system for a mean of 15.8 scores (range, 12-18 scores), of which there were 10 cases excellent, 6 cases good, 2 cases fair, with an excellent rate of 88.9% (16/18). All patients recovered well, and there were 2 cases of lateral femoral cutaneous nerve injury postoperative who had recovered one month later. There was no other postoperative complications.Conclusion:The anterior and posterior column and quadrilateral surface could be stabilized simultaneously by the anatomical supra-pectineal quadrilateral surface buttress plate without intraoperative shaping. Moreover, it is more likely to obtain a satisfactory clinical outcome by using this special plate with lower complications and rigid fixation. Therefore, it is a kind of internal fixation method worthy of promotion in the treatment of complex acetabular fractures.

ABSTRACT

Objective:To construct a Nomogram model in predicting recurrence-free survival (RFS) and overall survival (OS) at six months, one year and two years after hepatocellular carcinoma (HCC) resection by using inflammatory markers combined with other routine clinical indicators.Methods:The data of 314 patients with HCC who underwent first time hepatectomy at Beijing Chaoyang Emergency Rescue Center and Air Force Characteristic Medical Center from January 2013 to January 2018 were analyzed. HCC patients who underwent hepatectomy at the First Medical Center of PLA General Hospital from January 2011 to January 2016 ( n=106) were used as the external validation group. Univariate and multivariate Cox proportional risk model was used to analyze independent risk factors of recurrence and death in HCC patients. A Nomogram model was constructed based on independent risk factors. Validation of the efficacy of the Nomogram model was done based on external data. Results:In the experimental group, 174 patients relapsed. The median RFS was 26 months. The 6 months, 1 year and 2 years RFS were 26.8%, 43.9%, and 68.8%, respectively. A total of 142 patients had died. The median survival time was 30 months. The 6 months, 1 year and 2 years OS were 5.9%, 23.6% and 63.1%, respectively. In the external validation group, 63 patients had developed recurrence, with a median RFS time of 28 months. The 6 months, 1 year and 2 years RFS were 26.4%, 45.3%, 54.7%, respectively. The median survival time was 31 months. The 6 months, 1 year and 2 years OS were 7.5%, 25.5%, 46.6%, respectively. Tumor size (>6.0 cm, HR: 1.447), vascular invasion ( HR: 1.408), TBil (>0.94 mg/dl, HR: 1.949), NLR (>2.54, HR: 2.843), AGR (≤0.88, HR: 2.447) were independent risk factors of HCC recurrence ( P<0.05). Tumor size (>6.0 cm, HR: 2.207), vascular invasion ( HR: 1.529), and NLR (>2.54, HR: 2.708) were independent risk factors of death for HCC patients ( P<0.05). The C-indexes of half-year, one-year and two-year RFS were 0.764 (95% CI: 0.677-0.854), 0.710 (95% CI: 0.615-0.824) and 0.673 (95% CI: 0.601-0.786), respectively. The C-indexes of half-year OS, one-year OS and two-year OS were 0.729 (95% CI: 0.648-0.841), 0.708 (95% CI: 0.608-0.813) and 0.664 (95% CI: 0.618-0.771), respectively. Conclusion:In this study, the construction of a Nomogram model in predicting prognosis of HCC patients was helpful to guide clinicians in improving preoperative treatment plans and in providing ideas for individualized treatment of patients.

ABSTRACT

The incidence of fragility fractures of the pelvis (FFP) in elderly patients has been gradually increased. FFP has become another type of injury that threatens the lives of elderly patients because of high disability rate and mortality. The special physical condition of the elderly patients such as osteoporosis, chronic medical diseases and disability determines the specialty in diagnosis and treatment of FFP. The perioperative treatment is more difficult than other patients. FFP in elderly patients is different from the high violent mechanism of pelvis fractures in young patients, and its fracture morphology and classification are also varied. Surgical treatment is to stabilize the mechanical transmission structure of the pelvic ring, improve clinical symptoms, reduce long-term bed-related complications and restore painless daily self-care. In recent years, the surgical treatment of the pelvic fractures has made significant progress. However, there still remains controversy in treating FFP in elderly patients. The authors discuss the perioperative hot issues on FFP in elderly patients, hoping to realize the standard management of FFP.

ABSTRACT

Objective:To investigate the value and feasibility of early goal directed sedation (EGDS) in patients with acute brain injury.Methods:A total of 110 patients with acute brain injury who were admitted to intensive care unit (ICU) of the Third Medical Center of the Chinese People's Liberation Army General Hospital from January 2015 to March 2019 were included and randomly divided into EGDS group and standard sedation group (STD) using the random number table. Patients in the EGDS group were sedated by continuous intravenous infusion of dexmedetomidine (initial dose of 0.2 μg·kg -1·min -1) for 72 consecutive hours. Patients in the STD group received intravenous bolus of propofol as appropriate clinically. Richmond agitation-sedation score (RASS) and electroencephalogram bispectral index (BIS) were used to continuously monitor the level of sedation. All patients were given sufentanil for analgesia. Routine treatments such as dehydration and reduction of intracranial pressure with mannitol, hemostasis or antiplatelet therapy were given according to the patients' condition. Vital signs, acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) score, Glasgow coma scale (GCS) score, BIS value, artery blood gas analysis, duration of mechanical ventilation, analgesic dosage and adverse events were recorded in two groups before and 24, 48, and 72 hours after sedation. Results:① Among the 110 patients, patients who received the second surgery due to cerebral hemorrhage, had worsening of cerebral hernia, withdrew during the course of the study, or whose family members abandoned treatment were excluded from the study. Finally, 105 patients were enrolled in the study, including 56 patients in the EGDS group and 49 in the STD group. There was no significant difference in gender, age, types of brain injury, baseline APACHEⅡ or GCS score or rate of mechanical ventilation between the two groups. ② Compared with before sedation, heart rate (HR) significantly decreased till 72 hours after sedation in both groups, and the decrease in the EGDS groups was more obvious as compared with the STD group (bpm: 70.49±7.53 vs. 79.83±9.48, P < 0.05). Besides HR, significant improvement was found in the APACHEⅡ and GCS scores in the STD group at 72 hours of sedation as compared with before sedation, and no significant difference was found in other indicators. Compared with before sedation, arterial partial pressure of carbon dioxide (PaCO 2) was significantly increased from the 24th hour of sedation, mean artery pressure (MAP) was decreased significantly and GCS score, BIS value were increased significantly from the 48th hour of sedation, till 72 hours, which were all improved significantly as compared with the STD group [72-hour PaCO 2 (mmHg, 1 mmHg = 0.133 kPa): 40.30±5.98 vs. 31.57±8.20, 72-hour MAP (mmHg): 85.01±8.26 vs. 89.54±9.41, 72-hour GCS score: 8.62±3.34 vs. 7.89±2.74, 72-hour BIS: 60.87±24.79 vs. 56.68±33.43, all P < 0.05]. APACHEⅡ score was significantly lower only at the 72nd hour of sedation as compared with before sedation in the EGDS group, and no significant difference was found as compared with the STD group (17.10±7.05 vs. 18.90±3.32, P > 0.05). Oxygenation index (PaO 2/FiO 2) was significantly increased only at the 24th hour of sedation in the EGDS group as compared with the STD group (mmHg: 261.05±118.45 vs. 226.45±96.54, P < 0.05). ③ The duration of mechanical ventilation was significantly shorter in the EGDS group than that in the STD group (hours: 20.56±9.03 vs. 27.75±11.23, P < 0.05), and the total administered dose of sufentanil was significantly lower in the EGDS group than that in the STD group (μg: 79.16±26.76 vs. 102.46±35.48, P < 0.05). ④ Compared with the STD group, the incidence of bradycardia in the EGDS group was increased significantly [10.71% (6/56) vs. 6.12% (3/49), P < 0.05], while the incidence of tachycardia was decreased significantly [14.29% (8/56) vs. 38.78% (19/49), P < 0.05], but no significant difference was found in the incidence of hypotension [5.36% (3/56) vs. 4.08% (2/49), P > 0.05]. The incidence of unexpected extubation in the STD group was 4.08% (2/49), which did not occurre in the EGDS group. Conclusion:EGDS can improve the GCS score and BIS value of patients with acute brain injury, suggesting that the EGDS is safe and feasible, which can help improve neurological function in patients with acute brain injury.

ABSTRACT

Objective To explore the clinical efficacy of combined plates through superior?ilioinguinal approach for ace?tabular fractures involving anterior wall and anterior column. Methods Data of twelve patients with acetabular fractures involv?ing anterior column and anterior wall who were treated by combined plates from June 2015 to August 2017 were retrospectively an?alyzed. Among them 9 cases were males and 3 cases were females, with an average age of 55.4 years old (range, 22-69 years old). Three cases were combined with posterior hemitransverse fractures. Six cases were combined with posterior column fractures. The mean time from injury to operation was 7.2 d (range, 5-12 d). Simultaneous management of anterior wall and anterior column frac?tures were achieved through single superior?ilioinguinal approach using the novel combined plates in all patients. The image re?sults were evaluated by Matta’s standard and the functional outcome was evaluated by the Matta's improved Merle d'Aubigné?Pos?tel scores system at the final follow?up. Results All 12 patients were followed up for average 18.3 months (range, 12-24 months). Average blood loss was 560 ml (range, 200-1 200 ml) and average operative time was 102 min (range, 88-190 min). The mean time of bony union was 2.9 months (range, 2.5-4.5 months). The quality of postoperative fracture reduction was evaluated accord?ing to Matta’s standard, of which there were 7 cases anatomic, 3 cases satisfactory, and 2 cases unsatisfactory, with an anatomic or satisfactory rate of 83.3%(10/12). The average Matta’s improved Merle d’Aubigne?Postel score was 16.1 (range, 12-18), and there were 8 cases excellent, 2 cases good, 1 case fair and 1 case poor, with an excellent or good rate of 83.3%(10/12). Rupture of the peritoneum occurred in one patient during the surgery which was repaired immediately. One patient suffered obturator nerve palsy and was fully recovered in one year. No inguinal hernia, surgical site infection and femoral head avascular necrosis occurred. Con?clusion The combined plates could provide simultaneous fixation for anterior column and anterior wall fractures firmly through single superior?ilioinguinal approach. Satisfactory reduction and functional outcomes could be achieved by the novel plates.

ABSTRACT

Objective@#To understand the energy and major nutrients intake of high school students in Shanghai, and to provide basis for formulating target nutritional interventions and health education.@*Methods@#The probability-proportional-to-size sampling technique was used to select 19 high schools, from which 9 boys and 9 girls from same class were randomly recruited for each grade. A total of 900 high school students were surveyed on their energy and major nutrients intake.@*Results@#The medians of intake of energy, protein, fat, carbohydrate, calcium, sodium, iron, vitamin A, vitamin B-1, vitamin B-2, vitamin C and dietary fiber were 2 353 kcal/d, 97.3 g/d, 95.4 g/d, 265.4 g/d, 602.1 mg/d, 4 373 mg/d, 24.3 mg/d, 495.6 μgRE/d, 1.08 mg/d,1.21 mg/d, 83.2 mg/d and 1.01 g/d, respectively. Among of them, the medians of intake of energy, calcium, vitamin A, vitamin B-1, vitamin B-2, vitamin C and dietary fiber for boys and girls were lower than reference standard(P<0.05). The medians of intake of energy and major nutrients in high school students who lived in countryside were less than those lived in suburban and urban(P<0.05), except carbohydrates and iron. The percentages of energy supplied byprotein, fat and carbohydrate were 16.9%, 37.2%and 46.0%, respectively.@*Conclusion@#The energy and calorigenic nutrients intake can meet the demand of daily consumption in high school students in Shanghai, but the intake of dietary fiber, some minerals and vitamins have a various degrees of deficiency. The proportion of energy supplied bycalorigenic nutrients is unbalanced.

ABSTRACT

Objective To explore the clinical effectiveness and reliability of combined acetabular quadrilateral surface plates for the treatment of both column fractures.Methods From June 2016 to August 2017,data of 15 cases with acetabular both column fractures who were treated in our department were retrospectively analyzed.Among them 9 cases were male and 6 were female.The mean age was 42.8 years (range,26-68 years).All cases were both column fractures according to the LetournelJudet's classification,including 4 cases combined with posterior wall fracture.Before operation,the pelvic CT thin layer scanning data of patients were collected in DICOM format,and then the data were imported to print the simulated model by 3D printing technology in order to understand the characteristics of fracture directly.The contralateral half pelvis was mirror printed in order to simulate the placement of combined quadrilateral surface plates and preshape all plates.During operation,infrapectineal main plate,pubo-ischiatic plate and ilio-ischiatic plate were placed consequently to fix the anterior column,"middle column" and posterior column respectively.The pubo-ischiatic and ilio-ischiatic plates were combined with the main plate.All cases were operated by supra-ilioinguinal approach.Results The average incision length was 11 cm (range,9-13 cm).The average operative time was 150 min (range,100-240 min).The average blood loss was 850 ml (range,600-1500 ml).Once reduction was obtained,plates could be placed easily and adhere to bone surface well.The quality of postoperative fracture reduction was evaluated according to Matta standard,of which there were 9 cases excellent,4 cases good,and 2 cases poor,with an excellent rate of 86.7% (13/15).All patients were followed up for an average time of 10 months (range,6-12 months).At the latest follow-up,the average modified Merle d'Aubigne and Postel score was 16.4 (range,12-18),and there were 8 cases excellent,4 cases good,2 cases fair and 1 case poor,with an excellent rate of 80.0% (12/15).Conclusion For the treatment of acetabular both column fractures,the combined quadrilateral surface plates could resist the medial displacement of quadrilateral area,and on the other hand the total floating posterior column and ischium could be fixed firmly.At the same time,this plate system is a multi-dimensional framework fixation,which is more effective and safer with lower complications rate,resulting in a satisfactory clinical outcomes.
