To explore related factors of cubital tunnel syndrome caused by cubitus valgus deformity so as to provide theoretical basis for the cl inical treatment. Methods Between June 2002 and September 2008, 40 patients with cubital tunnel syndrome caused by cubitus valgus deformity underwent anterior subcutaneous ulnar transposition. Related factors wasanalysed through logistic regression analysis using scoring standard recommended by Yokohama City University. Results All 40 patients were followed up 27.5 months on average (range, 12-75 months). The duration of cubitus valgus deformity, cubitus valgus deformity angle, and the duration of paraesthesia and muscular atrophy were identified as related factors for ulnar neuropathy and the odds ratios were 1.005 (P=0.045), 9.374 (P=0.000), and 4.358 (P=0.010), respectively. The related prognosis factors were duration of paraesthesia and muscular atrophy, deformity angle, and age at surgery, with odds ratios of 8.489 (P=0.000), 2.802 (P=0.030), and 4.611 (P=0.031), respectively. Conclusion Related factors for ulnar neuropathy are durations of cubitus valgus deformity, cubitus valgus deformity angle, and duration of paraesthesia and muscular atrophy. Related factors for prognosis include age at surgery, cubitus valgus deformity angle, and duration of muscular atrophy. Early anterior subcutaneous ulnar transposition should be performed in patients with cubital tunnel syndrome caused by cubitus valgus deformity

Methods The general information and Zung′s self rating anxiety scale (SAS) were taken to analyze 219 patients from early November to early December 2009. Results The average SAS score of the 219 patients was 33.70±8.60, in which there were 17 patients (7.76%) with total scores ≥ 50 and anxiety. Multiple regression analysis showed that the age and temperature were related factors among age, gender, urban-rural differences, and fever. Conclusion The survey suggests that the pafients at the H1N1 influenza peak of fever clinics are significantly more anxious than normal anxiety. Out-patient work should strengthen psychological care to reduce and try to eliminate the anxiety of patients, in order to avoid adverse impact which is not conducive to control influenza outbreaks.
Objective To explore the correlative factors affecting the compl ications resulting from cement leakage after percutaneous kyphoplasty (PKP) in the treatment of osteoporotic vertebral body compression fractures (OVCF). Methods From February 2005 to October 2008, 71 patients with OVCF were treated by PKP and were retrospectively analyzed. There were 16 males and 55 females, and the average age was 71.5 years (range, 52-91 years). The average duration of disease was 5.7 months (range, 1-11 months). A total of 171 vertebra were involved in fracture including 19 cases of single vertebral fractures, 21 cases of double vertebral fractures, 20 cases of three vertebral fractures, and 11 cases of more than three vertebral fractures. All the treated vertebra were divided into acute (86 vertebra) or subacute (85 vertebra) state based on changes in MRI signal intensity. There was no radiculopathy or myelopathy. The average injected cement volumewas 4.6 mL (range, 1.5-6.5 mL). The treatment efficacy was assessed by observing the change in anterior and middle vertebral column height, Cobb angle, visual analogue scale (VAS) and Oswestry functional score at preoperation, 3 days after operation and last follow-up. The patients were divided into cement leakage group and no cement leakage group. All the compl ications were recorded, and then the correlative factors affecting the compl ications were analyzed. Results All the cases had rapid and significant improvement in back pain following PKP. All patients were followed up for 14 months (range, 7-18 months). There was no cement extravasation resulting in radiculopathy or myelopathy. Four patients (5.63%) had lung-related compl ications. During the follow-up, 9 recurrence vertebral fractures were observed in 6 patients (8.45%). The anterior and middle vertebral column height, Cobb angle, VAS and Oswestry score were significantly improved when compared with preoperation (P lt; 0.05). Cement leakage occurred in 17 (9.94%) vertebral bodies; of 17 cases, the cement leaked into the paravertebral space in 7 cases, intervertebral space in 6 cases, channel of needl ing insertion in 3 cases, and spinal canal in 1 case. Univariate analysis showed statistically significant differences (P lt; 0.05) in preoperative anterior and middle vertebral column height, injected cement volume and vertebral body wall incompetence between the cement leakage group and no cement leakage group. There were no significant differences (P gt; 0.05) in preoperative Cobb angle, freshness of vertebral fracture, location of operative vertebrae and operative approach between the two groups. Multiple logistic regression analysis showed that the injected cement volume [odds ratio (OR)=3.105, 95% confidence interval (CI)=1.674-5.759, P lt; 0.01] and vertebral body wall incompetence (OR=11.960, 95%CI=3.512-40.729, P lt; 0.01) were the predominant variable associated with the compl ications resulted fromcement leakage. Conclusion The injected cement volume and vertebral body wall incompetence were the factors affecting the compl ications. The improvement of surgical technique is the capital factor that may reduce the compl ications in the PKP.
Objective To explore the relative prognostic factors of Tile C pelvic injury after iliolumbar fixation. Methods Between March 2007 and March 2010, 60 patients with Tile C pelvic injuries were surgically treated with iliolumbar fixation, including 39 males and 21 females with an average age of 37 years (range, 17-66 years). Of them, 27 cases were classified as Tile C1, 20 as Tile C2, and 13 as Tile C3. The preoperative injury severity score (ISS) was 12-66 (mean, 29.4). The time from injury to surgery was 2-25 days (mean, 8.1 days). Iliolumbar fixation was performed in all patients. Unconditional logistic analysis was used to analyze the relationship between the age, sex, body mass index (BMI), operation opportunity, the preoperative combined injury, classification of fracture, the postoperative complication, reduction outcome, sacral nerve injury, and the time of physical exercise and the prognosis. Results All 60 patients were followed up 12-56 months (mean, 27.3 months). Infection of incisions occurred in 12 cases and were cured after dressing change; healing of incision by first intention was obtained in the other patients. Delay sacral nerve injury was found in 15 patients, 6 patients underwent nerve decompression, and 9 underwent conservative treatment. Ten patients had nail protrusion of Schanz screws at the posterior superior illac spine, and 3 patients had pain, which was relieved after removal of the internal fixator. One patient had bone-grafting nonunion of sacroiliac joint, which was improved by pressured bone graft. Five patients had the beam breakage without significant effect. Six patients had deep vein thrombosis, among them 4 underwent filter and 2 underwent nonsurgical treatment. The healing time of fracture was 3-6 months (mean, 3.9 months). According to the Matta function score, the results were excellent in 31 cases, good in 24 cases, fair in 3 cases, and poor in 2 cases with an excellent and good rate of 91.7% at last follow-up. Majeed score was 58-100 (mean, 86), 28 were rated as excellent, 12 as good, 16 as fair, and 4 as poor with an excellent and good rate of 66.7%. The logistic analysis showed that the age, sex, BMI, and postoperative complications were not prognostic factors; early operation (within 10 days), early function exercises (within 7 days), the better reduction quality, and the less sacral nerve injury were in favor of prognosis; and the worse preoperative combined injury and pelvic injury were, the worse the prognosis was. Conclusion Operation opportunity, the preoperative combined injury, reduction outcome, sacral nerve injury, and the time of physical exercise are all significantly prognostic factors of Tile C pelvic injuries
Objective To identify the factors which influence the effectiveness of clinical evaluation of undergraduate nursing students. Methods A self-made questionnaire was used in face-to-face interviews with 158 clinical teachers of undergraduate nursing students in four teaching hospitals in Sichuan. Results The main factors that influence the effectiveness of clinical evaluation of undergraduate nursing students included: clinical environment, duration of evaluation, degree of familiarity with the evaluation criteria of clinical teachers, and evaluation methods used by clinical teachers. The less important factors included: “halo-effect” of teachers to students, relationship between teachers and students, attitude towards evaluation and emotional status of clinical teachers. Conclusion It is of great importance to improve the clinical environment, provide enough time for clinical teachers to evaluate, cultivate and improve clinical teachers’ evaluation and competence, and establish a good relationship between teachers and students.This should improve the accuracy, objectivity and fairness of undergraduate nursing students’ clinical evaluation.
