Five fresh human forearms removed from cadavers were used to study the vascular concentration of the flexor digital tendons by stereology method. The results showed: (1) The Vv is 0.45%, and Lv is 1.9; (2) The vascular concentration of the flexor digital tendons of different fingers showed no significance statistically; (3) The vascular concentration of the tendons within the digital sheath was less than that outside the digital sheath (plt;0.01); (4) The vascular concentration of the tendons were decreasing gradually form the thum dto litter finger.
ObjectiveTo investigate the efficacy and safety of the phase Ⅰ corpus callosotomy in the treatment of adult refractory epilepsy. MethodsWe conducted a retrospective analysis of 56 adults with intractable epilepsy in Tangdu Hospital from January 2011 to July 2016.All patients were treated for the phase Ⅰ total corpus callosotomy, followed up 1~5 years after surgery. Results14 cases (25.0%) patients achieved complete seizure free after surgery, 19 cases (33.9%) whose seizures reduced more than 90%, 10 cases (17.9%) reduced between 50%~90%, 7 cases (12.5%) between 30%~50%, 6 cases (10.7%) decreased below 30%; Drop attacks of 47 cases (83.9%) patients disappeared. Postoperative complications occurred in 13 cases(23.2%), and most of them recovered well. 5 cases(8.9%) had long-term sensory disassociation, no serious complications and death. The percentage of patients reporting improvement in quality of life was 67.9%. ConclusionsFor patients with intractable epilepsy who can not undergo focal resection, Ⅰ phase total corpus callosotomy has a certain effect on reducing seizure frequency, eliminating drop attacks, and improving the quality of life.
Objective To investigate the long-term clinical results of treatment of adult unicameral bone cyst with cancellous allograft. Methods From 1993 to 1998, 15 patients with unicameral bone cyst were treated by allograft with lyophilized cancellous bone. Among 15 patients, there were 5 males and 10 females, aging 19-41 years with an average of 27 years. The average follow-up time was 7.5 years (6-11 years). The X-ray films were taken and the CT scanning were carried out. Results The X-ray films showed that the allograft particles became vague 2-3 months after operation, that the allograft particles fused and began to form new bone and the bone density increased 5 months after operation, and that new bone formation completed after 7 months of operation. At the end of follow-up, remodelling in new bone occurred. Reoccurrence was not found in all patients. The symptom of pain disappeared or relieved obviously. Conclusion Allograft of lyophilized cancellous bone is an effective treatment for adult unicameral bone cysts.
目的总结Millikan无张力疝修补术治疗腹股沟疝的经验。方法对笔者2008年1月至2010年1月期间完成的Millikan无张力疝修补术患者的临床资料进行总结、分析。结果本组 32例共35侧疝，按国内疝学组分型(2003年)，Ⅰ型2侧，Ⅱ型9侧，Ⅲ型21侧，Ⅳ型3侧。直疝6侧，斜疝29侧。其中行急诊疝修补术2例。术后发生尿潴留2例(6.25%),无切口感染、血肿、睾丸炎等并发症发生； 住院时间3~5 d，平均3.5 d。随访2~24个月，平均18个月，无复发及慢性疼痛者。结论Millikan手术是一种操作简便、安全、符合无张力疝修补原理的术式，适用于Ⅱ~Ⅳ型腹股沟疝的修补。
目的探讨成人Ⅰ型胆总管囊肿的诊断和治疗。方法回顾性分析1997年1月至2004年7月期间收治的8例成人Ⅰ型胆总管囊肿的临床资料。结果5例行胆总管囊肿全切除、RouxenY肝管空肠吻合术； 2例行囊肿部分切除、RouxenY囊肿空肠吻合术； 1例行囊肿部分切除、 RouxenY肝管空肠吻合术，术中常规行胆道镜检查，无一例手术死亡。8例患者术后平均随访2．8年(1~7年)，未发现胆道恶性肿瘤。1例行囊肿部分切除的患者，在术后出现3次右上腹绞痛，1次急性胆管炎表现，均经支持、对症、抗感染等治疗后好转。 结论 成人Ⅰ型胆总管囊肿的诊断主要依靠B超、逆行胰胆管造影(ERCP)或磁共振胆胰管造影（MRCP）检查，囊肿全切除、RouxenY肝管空肠吻合是安全、有效的手术方式，其疗效比较满意； 囊肿部分切除、RouxenY囊肿空肠吻合术虽疗效不及完整囊肿切除令人满意，但对于在技术上难以作到囊肿完全切除者，部分囊肿切除是明智的选择，建议术中常规胆道镜检查。
Objective To explore the effectiveness of arthroscopic binding fixation using suture through single bone tunnel for posterior cruciate ligament (PCL) tibial insertion fractures in adults. Methods Between October 2019 and October 2021, 16 patients with PCL tibial insertion fractures were treated with arthroscopic binding fixation using suture through single bone tunnel. There were 11 males and 5 females with an average age of 41.1 years (range, 26-58 years). The fractures were caused by traffic accident in 12 cases and sports in 4 cases. The time from injury to operation ranged from 2 to 10 days with an average of 6.0 days. The fractures were classified as Meyers-McKeever type Ⅱ in 4 cases and type Ⅲ in 9 cases, and Zaricznyi type Ⅳ in 3 cases. There were 2 cases of grade Ⅰ, 7 cases of grade Ⅱ, and 7 cases of grade Ⅲ in the posterior drawer test. There were 3 cases combined with lateral collateral ligament injury and 2 cases with meniscus injury. The visual analogue scale (VAS) score, Lysholm score, International Knee Documentation Committee (IKDC) score, and knee range of motion were used to evaluate knee joint function. The posterior drawer test and knee stability tester (Kneelax 3) were used to evaluate knee joint stability. The X-ray films were used to evaluate fracture reduction and healing. Results All incisions healed by first intention after operation. There was no incision infection, popliteal neurovascular injury, or deep venous thrombosis of lower limbs. All patients were followed up 6-12 months, with an average of 10 months. X-ray films at 6 months after operation showed the fractures obtained bone union. There were 11 cases of grade 0, 4 cases of gradeⅠ, and 1 case of grade Ⅱin posterior drawer test, showing significant difference when compared with preoperative results (Z=23.167, P<0.001). The VAS score, Lysholm score, IKDC score, knee range of motion, and the results of Kneelax3 examination all significantly improved when compared with preoperative results (P<0.05). Conclusion For adult patients with PCL tibial insertion fractures, the arthroscopic binding fixation using suture through single bone tunnel has the advantages of minimal trauma, good fracture reduction, reliable fixation, and fewer complications. The patient’s knee joint function recovers well.
ObjectiveTo review the progress of clinical diagnosis and treatment of chronic osteomyelitis in adults.MethodsThe literature related to chronic osteomyelitis in recent years was extensively reviewed, and the clinical diagnosis and treatment methods were summarized.ResultsClinical characteristics and laboratory examination can help to diagnose chronic osteomyelitis in adults. Pathogenic identification is the basis for choosing antibiotics. Diagnostic imaging is specific. The treatment includes systemic treatment and local treatment, and the local treatment is the key to radical cure.ConclusionThe diagnosis of chronic osteomyelitis in adults should be made as early as possible. According to the anatomical and physiological classification of the patients, the appropriate treatment plan should be made.
Objective To identify the clinical features and risk factors for mortality associated with severe influenza B pneumonia of adults admitted to respiratory intensive care unit (ICU). Methods Patients with confirmed influenza B infection and respiratory failure between February 2020 and February 2022 who were admitted to the ICU were sequentially included. Demographic features, clinical data, microbiological data, complications, and outcomes were collected. Univariate logistic regression analysis was performed to identify risk factors associated with hospital mortality. A comparison with severe influenza A pneumonia was made to explore the characteristics of influenza B virus-associated pneumonia. Results A total of 23 patients with influenza B pneumonia were included. The survival group included 18 patients and the death group included 5 patients, with an ICU mortality of 21.7%. The median age in the death group was 64 (64, 72.5) years, which was significantly older than the survival group, with a median age 59 (30.25, 64.25) years (P=0.030). Univariate logistic regression analysis indicated that SOFA score [odds ratio (OR) 1.307, 95% confidential interval (CI) 1.013 - 1.686, P=0.039], decreased hemoglobin (OR 0.845, 95%CI 0.715 - 0.997, P=0.046), and high blood urea nitrogen (BUN) (OR 1.432, 95%CI 1.044 - 1.963, P=0.026) were independent risk factors for hospital mortality. Compared with influenza A pneumonia, patients with severe influenza B pneumonia had more complications (60.0% vs. 87.0%, P=0.023). Conclusions The mortality of severe influenza B virus-associated pneumonia with was high. Increased SOFA score, anemia, and high BUN were risk factors for ICU mortality of severe influenza B infection in adults.
