RESUMO
Objective To assess the performance of PET-CT in pulmonary carcinoid and to evaluate the efficacy of lymph node metastasis.Methods We retrospectively collected the data of 33 patients with primary pulmonary carcinoid in our center between November 2008 and March 2017.The results of PET-CT were analysed and the relationship among pathological sub-type, tumor size and SUVmax was compared.Results Thirty-three patients had a diagnosis of carcinoid tumor, typical in 10 patients and atypical in 23 patients.The major axis of the tumor was positively correlated with the SUVmax value (P<0.001), and the mean SUVmax of the atypical carcinoid was higher than that of the typical carcinoid(11.27 vs 3.54).The major axis of the tumor was controlled.One-way covariance analysis suggested that the pathological subtype was related to SUVmax(P=0.012).Overall, PET-CT had a sensitivity of 66.7％(95％CI: 12.5％-98.2％) and specificity of 90.9％(95％CI:83. 0％-95.5％).Conclusion Atypical carcinoids showed higher SUVmax than typical carcinoids, but the PET-CT perform-ance of lung carcinoids is not specific.There was a high specificity in evaluating lymph node metastasis.
RESUMO
Objective To evaluate the effectiveness of the suture anchor in the treatment of acute closed distal achilles tendon rupture. Methods A retrospective review of clinical data in 25 patients with acute achilles tendon rupture was performed in the department of orthopedic trauma of Tianjin Hospital between October 2012 to January 2014. The operation was performed by standard approach, with the suture anchors to reconstruct the achilles tendon insertion, and the Krachow technique was used to suture the achilles tendon. All patients were followed up for 19~35 months. The situation of the wound healing, heel pain, and achilles tendon re-rupture were observed and analyzed. According to the passive range of motion of the bilateral ankle joint, the achilles tendon total rupture score (ATRS), the American orthopaedic foot and ankle society (AOFAS) score and functional recovery were assessed one year after operation. Results The operation was successfully completed in this group. The operation time was 25-35 min, the average time was (30.4 ± 4.8) min. No major vascular and nerve injury occurred in the operation. All patients were followed up. The wound healed well. No infection and skin necrosis, no heel pain and achilles tendon re-rupture were found during follow-up. There was no significant difference in mean passive plantar flexion between injured ankles and uninjured ankles one year after operation (44.36° ± 3.33° vs. 46.40°±4.53°, P>0.05). But mean passive dorsiflexion was lower in injured ankles than that of uninjured ankles (16.88°± 4.10° vs. 20.12°±3.21°,P<0.05). The mean ATRS score was 88.7±6.1 (range 79-97), and the mean AOFAS score was 92.4± 5.6 (range 76-100) at first postoperative year. According to the AOFAS scale, the results were excellent in 20 cases and good in 5 cases. Conclusion It was successful to repair the acute closed distal achilles tendon injuries with the suture anchors.
RESUMO
Objective To analysis the risk factors of cardiovascular events during periopemtive period undergoing hand surgery . Methods 197 cases of hand surgery in our hospital from 2009 to 2012 ,aged 21 to 74 years were selected .The general condition ,an-esthesia ,operative time and intraoperative hemodynamics (blood pressure> 20% ) were recorded ,postoperative follow-up and record the occurrence of cardiovascular events ,and factor analysis was carried on .Results In 48 hours ,23 patients were suffered from car-diovascular events ,and the total morbidity rate was 11 .7% ,in which sinus tachycardia was 3 case(1 .52% ) ,atrial fibrillation were 2 cases(1 .02% ) ,premature ventricular contractions were 4 cases(2 .03% ) ,the myocardial ischemia were 11 cases(5 .58% ) ,the angi-na pectoris were 3 cases(1 .52% ) ,the myocardial isehemia was 1case(0 .51% ) .Multiariable Logistic regression analysis showed that ,the influencing factors of perioperative cardiovascular events undergoing hand surgery were were diabetes mellitus (OR=2 .012 ,P=0 .023) ,coronary heart disease (OR=2 .301 ,P=0 .028) ,preoperative ST ischemic changes (OR=2 .942 ,P=0 .031) ,lip-id abnormalities(OR=3 .012 ,P=0 .019) and hemodynamics changes during operation(OR=3 .522 ,P=0 .020) .Conclusion The risk factors of perioperative cardiovascular events independent undergoing hand surgery might be diabetes ,coronary heart disease , preoperative ST ischemic changes ,intraoperative hemodynamic changes .
