Fibromuscular dysplasia is the second commonest anatomical abnormality apart from multiple renal arteries in the potential live donors. Pretransplant evaluation of the donors may include an angiography to evaluate the renal arteries, and failure to recognize renal arterial stenosis, particularly fibromuscular dysplasia, by noninvasive methods may eventually lead to hypertension and ischemic renal failure. We report a case of fibromuscular dysplasia that was undetected by computed tomographic angiography prior to donation. One year after kidney donation, it rapidly progressed to severe symptomatic stenosis with hypertension and acute renal failure. Following renal artery angioplasty, her blood pressure normalized over a period of 2 weeks without any need for antihypertensive medications and the serum creatinine returned to her baseline. The acceptability of renal donors with fibromuscular dysplasia depends on the age, race and the availability of the other suitable donors. Mild fibromuscular dysplasia in a normotensive potential renal donor cannot be considered a benign condition. Such donors need regular follow-up postdonation for timely detection and treatment.  相似文献

Morphologic features of Burkitt lymphoma (BL) and diffuse large B-cell lymphoma (DLBCL) overlap. No single phenotypic marker or molecular abnormality is pathognomonic. We tested a panel of 8 germinal center (GC) and activated B-cell (ABC) markers for their ability to separate BL and DLBCL. We diagnosed 16 BL and 39 DLBCL cases from 21 patients with AIDS and 34 without AIDS based on traditional morphologic criteria, Ki-67 proliferative index, and c-myc rearrangement (fluorescence in situ hybridization). After immunohistochemically staining tissue microarrays of BL and DLBCL for markers of GC (bcl-6, CD10, cyclin H) and ABC (MUM1, CD138, PAK1, CD44, bcl-2), we scored each case for the percentage of positive cells. Hierarchical clustering yielded 2 major clusters significantly associated with morphologic diagnosis (P < .001). For comparison, we plotted the sum of the GC scores and ABC scores for each case as x and y data points. This revealed a high-GC/low-ABC group and a low-GC/high-ABC group that were associated significantly with morphologic diagnosis (P < .001). Protein expression of multiple GC and ABC markers can separate BL and DLBCL.  相似文献

BackgroundTreatment options for metastatic osseous lesions of the proximal femur include hemiarthroplasty (HA) or total hip arthroplasty (THA) depending on lesion characteristics and patient demographics. Studies assessing short-term outcomes after HA/THA in this patient population are limited. Therefore, the purpose of this present study was to identify short-term rates of morbidity and mortality after HA/THA for pathological proximal femur fractures, as well as readmission and reoperation rates and reasons.MethodsThis study utilized a large, prospectively collected registry to identify patients who underwent HA/THA between 2011 and 2018. Patients were stratified by indication for surgery, including pathological fracture, nonpathological fracture, and osteoarthritis. Baseline patient characteristics and postoperative complications were compared using bivariate and/or multivariate analysis.ResultsIn total, 883 patients undergoing HA/THA for a pathological fracture were identified. Relative to an osteoarthritis cohort, these patients tended to be older, had a lower body mass index, and had significantly more preoperative comorbidities. These patients had high rates of total complications (13.93%), including thirty-day mortality (3.29%), unplanned return to the operating room (4.98%), and pulmonary complications (3.85%). Patients with pathological fracture had a longer operative duration relative to osteoarthritis and nonpathological cohorts (+27 and +25 minutes, respectively), despite having high rates of HAs performed.ConclusionPatients undergoing hip arthroplasty for pathologic proximal femur fracture have increased morbidity and mortality relative to an osteoarthritis cohort. However, patients with a pathological fracture have similar rates of morbidity and mortality when compared with a nonpathological fracture cohort, but did experience higher rates of perioperative blood transfusion and unplanned readmissions.Level of EvidenceIII.  相似文献

The COVID-19 pandemic has affected the ability of the sports medicine physician to be present to participate in in-person sideline evaluation of the injured athlete. The purpose of this review is to assess existing literature regarding the utilization of telehealth for sideline evaluation and management of the injured athlete, as well as to identify further areas of research. With the rapid incorporation of telehealth visits, the utilization and capabilities of telemedicine continue to expand. A number of evidence-based resources are available to support medical providers to develop and utilize video evaluation for the sideline evaluation of sports-related injuries. Future research, including the development of validated, modified examination techniques and technologies, will allow for improved interactive physical examinations, which may be better utilized for sideline evaluation.  相似文献

ObjectivesThe COVID-19 pandemic has contributed to a shift from in-person to remote mental health care. While remote care methods have long existed, their widespread use is unprecedented. There is little research about mental health care user and provider experiences with this transition, and no published studies to date have compared satisfaction between these groups.MethodsCanadian mental health care users (n = 332) and providers (n = 107) completed an online self-report survey from October 2020 to February 2021 hosted by the Canadian Biomarker Integration Network in Depression. Using a mixed-methods approach, participants were asked about their use of remote care, including satisfaction, barriers to use, helpful and unhelpful factors, and suggestions for improvement.ResultsOverall, 59% to 63% of health care users and 59% of health care providers were satisfied with remote care. Users reported the greatest satisfaction with the convenience of remote care, while providers were most satisfied with the speed of provision of care; all groups were least satisfied with therapeutic rapport. Health care providers were less satisfied with the user-friendliness of remote care (P < 0.001) than users, while health care users were less satisfied than providers with continuity of care (P < 0.001). The use of a video-based platform was associated with remote care satisfaction among health care users (P < 0.02), and qualitative responses support the importance of visual cues in maintaining therapeutic rapport remotely. The majority of users (55%) and providers (87%) reported a likelihood of using remote care after the pandemic.ConclusionsRemote mental health care is generally accepted by both users and providers, and the majority would consider using remote care following the pandemic. Suggestions for improvement include greater use of video, increased attention to body language and eye contact, consistency with in-person care, as well as increased provider training and administrative support.  相似文献

Head and neck cancer (HNC) is third highest prevalent cancer among Indian which constitutes about 25–30% of all the cancer in India. Further, out-of-pocket expenditure (OOPE) covers around 67% of total healthcare expenditure and direct medical cost is key factor responsible for raised OOPE in India. Thus, we aimed to quantify total direct medical cost and OOPE associated with HNC management among HNC patients using “Ayushman Bharat Arogya Karnataka scheme” (ABArK scheme). A retrospective study was conducted for the duration of 6 months to collect the data related to total direct medical cost, coverage of “ABArK Scheme” and OOPE of past 2 years of HNC patients. The data of HNC patients above 18 years of age utilizing “ABArK scheme” were included in the study whereas data of patients utilizing other healthcare schemes and incomplete data on target schemes were excluded. A total of 196 patients (54.1%) utilized the “ABArK Scheme” out of 362 HNC patients treated in past 2 years. Among 196 patients, males (76.5%) were predominant over females (23.5%) with the mean age of 53.60 ± 11.58 years. We found that INR 17,370,279 as the total direct medical expenditure for the management of HNC patients of which around 87.465% was covered by “ABArK Scheme” minimizing the OOPE up to INR 3,297,970. Thus, Introduction and implementation of novel healthcare policies like “ABArK Scheme” can counteract financial burden of cancer management by significantly reducing OOPE which could be milestone achievement for the low-middle income countries like India.  相似文献

Hemorrhage is recognized as a new independent predictor of adverse outcomes following acute myocardial infarction. However, the mechanisms of its effects are less understood. The aim of our study was to probe the downstream impact of hemorrhage towards chronic remodeling, including inflammation, vasodilator function and matrix alterations in an experimental model of hemorrhage. Myocardial hemorrhage was induced in the porcine heart by intracoronary injection of collagenase. Animals (N = 18) were subjected to coronary occlusion followed by reperfusion in three groups (six/group): 8 min ischemia with hemorrhage (+HEM), 45 min infarction with no hemorrhage (I ? HEM) and 45 min infarction with hemorrhage (I + HEM). MRI was performed up to 4 weeks after intervention. Cardiac function, edema (T2, T1), hemorrhage (T2*), vasodilator function (T2 BOLD), infarction and microvascular obstruction (MVO) and partition coefficient (pre‐ and post‐contrast T1) were computed. Hemorrhage was induced only in the +HEM and I + HEM groups on Day 1 (low T2* values). Infarct size was the greatest in the I + HEM group, while the +HEM group showed no observable infarct. MVO was seen only in the I + HEM group, with a 40% occurrence rate. Function was compromised and ventricular volume was enlarged only in the hemorrhage groups and not in the ischemia‐alone group. In the infarct zone, edema and matrix expansion were the greatest in the I + HEM group. In the remote myocardium, T2 elevation and matrix expansion associated with a transient vasodilator dysfunction were observed in the hemorrhage groups but not in the ischemia‐alone group. Our study demonstrates that the introduction of myocardial hemorrhage at reperfusion results in greater myocardial damage, upregulated inflammation, chronic adverse remodeling and remote myocardial alterations beyond the effects of the initial ischemic insult. A systematic understanding of the consequences of hemorrhage will potentially aid in the identification of novel therapeutics for high‐risk patients progressing towards heart failure.  相似文献
