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.
Objective To summarize the methods of repairingthe urethral defect in the penis of an adult and the clinical application of the island skin flaps of the scrotum septum to the reparative treatment. Methods From January 2000 to November 2005, twenty-six cases of urethral defect in penis, including 16 cases of congenital urethral defect, 6 cases of traumatic urethral defect in middle penis, and 4 cases of distal urethral defect, were repairedby the local penis fascia flaps.The island skin flaps of the scrotum septum were transferred to cover the penis wound. The pedicle contained the artery of the posterior scrotum and the artery of the anterior scrotum. The flap taken from the scrotum septum was 2.5 cm×5.5 cm in area. Results After a follow-up of 7months to 4 years, all the 26 patients had the healing of the first intention without urethral fistula, urethral narrowness or penis curvature, except 4 patients who developedinfection and leakage of urine, but the wounds healed spontaneously 2-4 weeks after operation. Conclusion The penis fascia flaps and the island skin flaps of the scrotum septum can be used to repair the urethral defect in the penis of an adult. The blood supply to the flaps is sufficient and all theflaps can survive well. A good shape and function of the penis can be obtained.
【Abstract】ObjectiveThe growing gap between the number of patients waiting for transplantation and available organs has continued to be the number one issue facing the transplant community. The major limitation of adult-to-adult living donor liver transplantation (LDLT) is the adequacy of the graft size. But donor safety is the major concern in LDLT. Methods Two patients with end-stage liver disease were successfully performed adult-to-adult LDLT using dual grafts in our division. One patient’s donors are left lobe and left lobe from his two old sisters , respectively. The other graft are right lobe from his 56 years-old mother and left lobe splitting from a cadaveric organ donor (the other part of split-liver transplants from the the cadaveric organ donor offer to another adult donor ). Results Both recipients and three donors display good graft function and normal triangularshape regeneration of their liver grafts after liver transplantation. There was neither a mortality nor a serious complications in the donors. Conclusion The critical issue of LDLT is donor morbidity. Dual grafts from two living donors can help to alleviate the problem of small-for-size grafts and yet secure the safety of the donor. But the complicated surgical technique give a great challenge for liver transplant surgeons.
ObjectiveTo systematically review the risk factors of related infections on the totally implantable venous access device (TIVAD) in adult.MethodsPubMed, EMbase, CINAHL, The Cochrane Library, CBM, WanFang Data, CNKI and VIP databases were electronically searched to collect case-control studies and cohort studies about the risk factors of TIVAD-related infections in adult from inception to April 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by using RevMan 5.3 software.ResultsA total of one case-control study and 12 retrospective cohort studies involving 9 166 patients were included. The results of meta-analysis showed that: longer catheter utilization-days in the previous months (RR=1.06, 95%CI 1.02 to 1.10, P=0.001), inpatient treatment (RR=2.53, 95%CI 1.68 to 3.81, P<0.000 01), palliative care (RR=2.71, 95%CI 1.77 to 4.15,P<0.000 01), parenteral nutrition (RR=3.89, 95%CI 2.37 to 6.40,P<0.000 01), neutropenia (RR=2.20, 95%CI 1.30 to 3.72,P=0.003) and haematological malignancies (RR=3.54, 95%CI 2.03 to 6.17, P<0.000 01) were associated with increased risk of TIVAD-related infections in adult.ConclusionCurrent evidence shows that the risk factors of TIVAD-related infections include catheter utilization-days in the previous months, inpatient, palliative care, parenteral nutrition, neutropenia and hematological malignancies. Due to limited quality and quantity of the included studies, more high-quality studies are needed to verify conclusion.
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.
