The most common cause of mortality after a kidney transplant is a cardiovascular event. This is why most patients with poor cardiovascular status are denied a transplant. A 70-year-old male, ESRD from hypertensive nephropathy, was declined renal transplantation in the United States for advanced age, severe coronary disease and abdominal aortic aneurysm. The patient sought a second chance at a possible transplantation here in the Philippines. After a comprehensive cardiovascular evaluation, he underwent coronary artery bypass graft for a three-vessel disease followed by endovascular aneurysm repair (EVAR) which he tolerated well. After four weeks, he underwent a living-related kidney transplantation with immediate allograft function. On postoperative day 5, after catheter removal, the patient was unable to void spontaneously. He was diagnosed with benign prostatic obstruction and underwent transurethral resection of the prostate. He tolerated this and voided freely since catheter removal. One year later, the patient has a functioning allograft and stable cardiac status. High risk patients with cardiovascular disease may be given a chance at kidney transplantation after a meticulous evaluation and optimization.

Oliguria or anuria in the postoperative period of a post-transplant patient must alert the transplant team for a possibility of vascular problem and requires high clinical suspicion for early diagnosis and prompt decision making.

We report a case of sudden anuria in a renal transplant recipient during the immediate post-operative period, wherein prompt decision to re-operate and explore identified an external iliac artery dissection compromising the perfusion to the renal allograft. The dissected segment was irreparable, hence, was resected and reconstructed using a non-autogenous graft, restoring the perfusion to the allograft and lower limb. The renal graft was explanted, re-perfused and subsequent end to side anastomosis of the allograft arteries to the vascular graft was done. The patient had improved diuresis and decreasing creatinine trend as well as absence of lower extremity ischemic symptoms during the postoperative period.

Polytetrafluoroethylene (PTFE) interposition is an essential salvage technique for restoring blood flow in cases of external iliac artery dissection during renal transplantation.

To change the traditional hospital medical supplies rough management mode, the hospitals build an information material management platform which combines suppliers and hospitals, information systems and smart devices, clinical needs and professional operations innovatively. Finally, a lean management system called SPD is formed under the guidance of supply chain integration and supported by supply chain management theory and information technology. It has realized the whole process of consumables circulation information traceability, intelligent service in the hospital, and refined management of consumption settlement. The application of SPD in hospitals effectively improves the informatization level and overall operation efficiency of medical consumables management which is an important part of hospital information construction.

There is currently a huge worldwide demand for donor kidneys for organ transplantation. Consequently, numerous marginal donor kidneys, such as kidneys with microthrombi, are used to save patients' lives. While some studies have shown an association between the presence of microthrombi in donor kidneys and an increased risk for delayed graft function (DGF) (McCall et al., 2003; Gao et al., 2019), other studies have demonstrated that microthrombi negatively impact the rate of DGF (Batra et al., 2016; Hansen et al., 2018), but not graft survival rate (McCall et al., 2003; Batra et al., 2016; Gao et al., 2019). In contrast, Hansen et al. (2018) concluded that fibrin thrombi were not only associated with reduced graft function six months post-transplantation but also with increased graft loss within the first year of transplantation. On the other hand, Batra et al. (2016) found no significant differences in the DGF rate or one-year graft function between recipients in diffuse and focal microthrombi groups. To date, however, the overall influence of donor kidney microthrombi and the degree of influence on prognosis remain controversial, necessitating further research.

BACKGROUND: Although the need for consolidation chemotherapy after successful induction therapy is well established in patients with acute myeloid leukemia (AML) in first complete remission (CR1), the value of consolidation chemotherapy before allogeneic hematopoietic stem cell transplantation remains controversial. METHODS: We retrospectively compared the effect of the number of pre-transplant consolidation chemotherapies on outcomes of human leukocyte antigen-matched sibling stem cell transplantation (MSDT) for patients with AML in CR1 in multicenters across China. In our study, we analyzed data of 373 AML patients in CR1 from three centers across China. RESULTS: With a median follow-up of 969 days, patients with ≥ 3 courses of consolidation chemotherapy had higher probabilities of leukemia-free survival (LFS) (85.6% vs . 67.0%, P < 0.001) and overall survival (89.2% vs . 78.5%, P  = 0.007), and better cumulative incidences of relapse (10.5% vs . 19.6%, P  = 0.020) and non-relapse mortality (4.2% vs . 14.9%, P  = 0.001) than those with ≤ 2 courses of consolidation chemotherapy. Pre-transplantation minimal residual disease-negative patients with AML in CR1 who received MSDT with ≥ 3 courses of consolidation chemotherapy had a higher probability of LFS (85.9% vs . 67.7%, P  = 0.003) and a lower cumulative incidence of relapse (9.6% vs . 23.3%, P  = 0.013) than those with ≤ 2 courses. CONCLUSION Our results indicate that patients with AML in CR1 who received MSDT might benefit from pre-transplant consolidation chemotherapy.

OBJECTIVE: To investigate the long-term effectiveness of uncemented allograft-prosthesis composite (APC) for reconstruction of bone defects after proximal femur tumor resection. METHODS: Between June 2007 and March 2014, 21 patients who underwent uncemented APC reconstruction of proximal femur after tumor resection were retrospectively evaluated. There were 9 males and 12 females with an average age of 33.2 years (range, 19-54 years). There were 9 cases of giant cell tumor of bone, 5 cases of osteosarcoma, 4 cases of osteoblastic osteosarcoma, 2 cases of chondrosarcoma, and 1 case of undifferentiated pleomorphic sarcoma. Thirteen cases of benign bone tumors were all classified as stage 3 by Enneking staging; and 8 cases of malignant bone tumors were classified as grade ⅡB in 7 cases and grade ⅡA in 1 case according to the American Joint Committee on Cancer (AJCC) staging system. Among them, 7 patients underwent reoperation after recurrence, and the rest were primary operations; 8 patients presented with pathological fractures. The preoperative Harris hip score (HHS) and American Musculoskeletal Tumor Society (MSTS) score was 40 (30, 49) and 9.1±3.5, respectively. The length of osteotomy was 80-154 mm, with an average of 110 mm. At 1 year after operation and last follow-up, HHS and MSTS scores were utilized to evaluate the function of hip joint; the gluteus medius strength score was used to evaluation of the hip abduction function. Image examinations were taken at 1, 3, 6, 9, and 12 months after operation and every year thereafter to assess the union of allograft-host bone interfaces. Intra- and post-operative complications were also recorded. RESULTS: All patients were followed up 84-163 months (mean, 123.5 months). At 1 year after operation and last follow-up, the HHS and MSTS scores significantly improved when compared with the preoperative scores ( P<0.05). However, there was no significant difference in the HHS score, MSTS score, and gluteus medius strength score between the two time points after operation ( P>0.05). Image examination showed that all allograft-host bone interfaces achieved union after 5-10 months (mean, 7.6 months). At last follow-up, all patients had bone resorption, including 11 severe cases, 4 moderate cases, and 6 mild cases; the bone resorption sites included Gruen 1, 2, and 7 regions. Complications included 10 fractures and 1 prosthetic fracture. Local recurrence occurred in 3 patients and pulmonary metastasis in 3 patients. CONCLUSION Uncemented APC is a reliable method for the reconstruction of bone defects after proximal femur tumor resection. It has the good long-term effectiveness and possesses obvious advantages in the union at the bone-bone surface.

OBJECTIVE: To evaluate the clinical outcomes of allogeneic femoral head as strut allograft combined with proximal humeral internal locking system (PHILOS) in the treatment of proximal humeral Neer grade Ⅳ fracture with humeral head collapse. METHODS: From January 2018 to November 2020, 18 patients with Neer grade Ⅳ fracture with humeral head collapse were treated with strut allograft with PHILOS, including 4 males and 14 females, aged from 55 to 78 years old, with an average of (68.11±7.20) years old. The operation time, intraoperative bleeding, postoperative drainage volume, fracture healing time, neck-shaft angle and the height of the humeral head, failure of internal fixation the shoulder function at the last follow-up was assessed using Neer's scoring system. RESULTS: All 18 patients were followed up, and the duration ranged from 10 to 12 months, with an average of (11.08±0.65) months. The operation time was (66.44±5.06) min, the intraoperative bleeding volume was (206.67±36.14) ml, the postoperative drainage volume was (76.11±9.63) ml, and the fracture healing time was (17.28±3.92) weeks. At the last follow-up, the degree of loss of neck-shaft angle was (5.44±0.86) ° and the loss of the height of humeral head was (1.43±0.27) mm. All 18 patients had healing without complications such as fracture, withdrawal, penetration of internal fixation and necrosis of humeral head. According to Neer's evaluation standard, the total score was (89.61±5.60), 10 cases got an excellent result, 6 good, 2 fair. CONCLUSION Allogeneic femoral head combined with PHILOS is an appropriate treatment for the four-part proximal humerus fractures with humeral head collapse, exhibiting good clinic outcome.

OBJECTIVE: To compare the clinical efficacy of locking plate fixation with a fibular strut allograft (FA group) and locking plate fixation alone (LP group) in the treatment of proximal humeral fractures in adults by Meta-analysis. METHODS: Databases including PubMed, The Cochrane Library, Embase, Chinese BioMedical Literature Database(CBM), China National Knowledge Infrastructure(CNKI), WanFang Data, and China Science and Technology Journal Database (cpvip Database) were searched by computer from establishing to March 2020 to collect studies about locking plate fixation with fibular strut allograft versus locking plate fixation alone for proximal humeral fractures in adults. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. The postoperative humeral head height changes, neck-shaft angle changes, Constant-Murley score, American Shoulder and Elbow Surgeons(ASES)score, visual analogue scale(VAS), varus malunion rate, and screw penetration rate were compared by RevMan 5.3 software for Meta-analysis. RESULTS: Ten cohort studies were enrolled in a total of 749 patients, 300 patients in the FA group and 449 patients in the LP group. The results of Meta-analysis showed that locking plate with fibular strut allograft was superior to locking plate fixation alone in the changes in humeral head height [MD=-2.69, 95%CI(-3.24, -2.13), P<0.000 01], the changes in neck-shaft angle [MD=-5.65, 95%CI(-7.18, -4.12), P<0.000 01], Constant-Murley score [MD=9.00, 95%CI(4.26, 13.73), P=0.000 2], the ASES score [MD=5.56, 95%CI(4.29, 6.84), P=0.000 01], VAS score [MD=-0.23, 95%CI(-0.37, -0.09), P=0.001], the varus malunion rate [RR=0.22, 95%CI(0.09, 0.53), P=0.000 7] and the screw penetration rate [RR=0.26, 95%CI(0.13, 0.55), P=0.000 3], respectively.While there was no significant difference in the rate of osteonecrosis of the humeral head [RR=1.18, 95%CI(0.57, 2.45), P=0.65]. CONCLUSION For proximal humeral fractures in adults, current evidence shows that locking plate fixation with fibular strut allograft is superior to single locking plate fixation in improving postoperative radiological outcomes and shoulder function, relieving postoperative pain, reducing varus malunion rate and screw penetration rate. However, the efficacy in decreasing the osteonecrosis rate is not clear. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify the above conclusion.

OBJECTIVE: To investigate the short-term clinical effect of double channel decompression and bone grafting through the greater trochanter combined with allograft fibula propping in the treatment of osteonecrosis of femoral head (ONFH). METHODS: Twenty two patients (23 hips) with osteonecrosis of the femoral head were included from November 2017 to February 2019. According to Association Research Cirulation Osseous(ARCO) staging, there were 13 hips at stageⅡgroup, aged from 20 to 48 years old with an average of(32.5±8.5)years old;10 hips at stageⅢgroup, aged from 18 to 45 years old with an average of(32.7±8.6) years old. A single approach through the greater trochanterwas used for decompression, bone grafting and fibula support. Harris scoring system was used to evaluate the function of hip joint before and after implantation, and the anteroposterior and lateral X-ray films of hip joint were taken at 3, 6, 12 and 18 months after implantation to observe and analyze the progress of femoral head necrosis and regeneration. RESULTS: All patients were followed up, and the duration ranged from 12 to 18 months with an average of (14.6±2.1) months. Harris score of stageⅡand stageⅢpatients increased from 73.2± 5.5 and 66.5±3.4 to 87.6±8.7( CONCLUSION The effect of double trochanteric decompression and bone grafting combined with fibular allograft propping in the treatment of early and middle stage avascular necrosis of the femoral head is good, especially suitable for young and middle aged patients with ARCOⅡstage avascular necrosis of the femoral head.
