We conducted a systematic review regarding the efficacy and outcome of endovascular treatment of infected iliofemoral arterial pseudoaneurysms with covered stents. 35 cases were identified, including 5 own. 22 pseudoaneurysms were located in the femoral area and 13 in the iliac vessels. The most commonly reported complaints were pulsatile groin mass (40 %), sepsis (37.1 %), active bleeding (31.4 %), and groin infection with purulent discharge (17.1 %). S. aureus (65.7 %) and Streptococcus species (22.9 %) were the most common microbes isolated...

Travis J Dekker, Peter White, Samuel B Adams
BACKGROUND: Bone graft substitutes are often required in patients at risk for nonunion, and therefore, an allograft that most closely mimics an autograft is highly sought after. This study explored the utility and efficacy of a cellular bone allograft used for foot and ankle arthrodesis and revision nonunion procedures in a patient population at risk for nonunion. METHODS: An institutional review board-approved retrospective review of consecutive patients who underwent arthrodesis and revision nonunion procedures with a cellular bone allograft was performed at a single academic institution...

Many antihypertensive agents have been demonstrated to assist in preservation of kidney function, among them those that modulate calcium channels. Calcium channel blockers may also be of value in protecting hemodialysis patients from complications of sepsis. In diabetic recipients of kidney transplant allografts treated with cyclosporine, calcium channel blockade has been retrospectively linked to improved graft preservation and to fewer episodes of sepsis. This brief review outlines clinical and experimental publications on potential protection from sepsis by addition of calcium channel blockers to standard antibiotic therapy in individuals who may or may not have normal kidney function, or in the presence or absence of immunosuppression...

BACKGROUND: Patients with coronary artery disease (CAD) are characterized by an impaired cardiometabolic risk profile including high levels of atherogenic apolipoprotein (apo) B-containing lipoprotein levels. Genetic studies have highlighted a critical role for proprotein convertase subtilisin/kexin type 9 (PCSK9) in lipoprotein metabolism and CAD risk. OBJECTIVE: To determine whether improving dietary quality and increasing physical activity levels improve parameters of the cardiometabolic risk profile such as plasma apoB and PCSK9 levels in patients with CAD...

BACKGROUND: Patients with severe familial hypercholesterolemia (FH) are often unrecognized despite typical presentation. The introduction of PCSK9 inhibitors opens new therapeutic options and emphasizes the need for identification of severe FH patients. OBJECTIVES: The objective was identification, characterization, and management of severe FH patients by screening of cardiac catheterization (CC) database. METHODS: Retrospective analysis of CC database from 2002 to mid-2015 was performed for low-density lipoprotein cholesterol (LDL-C) ≥130 mg/dL (n = 2383)...

To examine the diagnostic value of serum ferritin, the associated risk factors, and cytokine profiles of hemophagocytic syndrome (HPS) following allogeneic hematopoietic cell transplantation (allo-HCT), we retrospectively analyzed data from patients undergoing allo-HCT between 2006 and 2012. Of 223 eligible patients, 18 patients developed HPS. A serum ferritin level above 30,000 μg/l was highly specific for the detection of HPS (specificity, 93%). The one-year survival rate for HPS was significantly lower than that of non-HPS patients (37...

Complications of allogeneic hematopoietic stem cell transplantation (HSCT) have been attributed to immune cells transferred into the patient with the graft. However, a detailed immune cell composition of the graft is usually not evaluated. In the present study, we determined the level of variation in the composition of immune cells between clinical HSCT grafts and whether this variation is associated with clinical outcome. Sizes of major immune cell populations in 50 clinical grafts from a single HSCT Centre were analyzed using flow cytometry...

BACKGROUND: After a severe shortage of brain-dead donors, the demand for heart transplantation has never been greater. In an attempt to increase organ supply, abdominal and lung transplant programs have turned to the donation after circulatory-determined death (DCD) donor. However, because heart function cannot be assessed after circulatory death, DCD heart transplantation was deemed high risk and never adopted routinely. We report a novel method of functional assessment of the DCD heart resulting in a successful clinical program...

There are >100,000 patients waiting for kidney transplants in the United States and a vast need worldwide. Xenotransplantation, in the form of the transplantation of kidneys from genetically engineered pigs, offers the possibility of overcoming the chronic shortage of deceased and living human donors. These genetic manipulations can take the form of (i) knockout of pig genes that are responsible for the expression of antigens against which the primate (human or nonhuman primate) has natural "preformed" antibodies that bind and initiate complement-mediated destruction or (ii) the insertion of human transgenes that provide protection against the human complement, coagulation, or inflammatory responses...

CMV infection in kidney transplant recipients (KTRs) has been associated with an increased risk for graft loss and reduced host survival. CMV promotes persistent expansions of NK cells expressing the CD94/NKG2C receptor. The NKG2C (KLRC2) gene is frequently deleted, and copy number influences the adaptive response of NKG2C(+) NK cells. The distribution of NKG2C(+) NK cells and NKG2C genotypes (NKG2C(+/+), NKG2C(+/del), NKG2C(del/del)) were studied in cross-sectional (n = 253) and prospective (n = 122) KTR cohorts...

Myelodysplastic syndrome (MDS) and myeloproliferative disorders are rare in children; they are divided into low-grade MDS (refractory cytopenia of childhood [RCC]), advanced MDS (refractory anemia with excess blasts in transformation), and juvenile myelomonocytic leukemia (JMML), each with different characteristics and management strategies. Underlying genetic predisposition is recognized in an increasing number of patients. Germ line GATA2 mutation is found in 70% of adolescents with MDS and monosomy 7. It is challenging to distinguish RCC from aplastic anemia, inherited bone marrow failure, and reactive conditions...

REVIEW
Sean Robinson Smith, Arash Asher
Chronic graft-versus-host disease is a potentially debilitating complication of allogeneic hematopoietic stem cell transplantation. Due to the direct inflammatory effects of the disease on tissue, and the impact on muscle and bone of the high-dose glucocorticoid immunosuppression used to treat the disease, patients are at risk of developing multifactorial functional impairment. This review outlines the clinical assessment and rehabilitation interventions to manage aspects of the disease that cause the most impairment: involvement of the skin/fascial and cardiopulmonary organ systems, as well as steroid-induced myopathy and bone and joint destruction...

BACKGROUND: Pterygium, a growth of the conjunctiva over the cornea, is a progressive disease leading in advanced stages to visual impairment, restriction of ocular motility, chronic inflammation and cosmetic concerns. Surgical removal is the treatment of choice, but recurrence can be a problem. Currently the best surgical option in terms of recurrence is conjunctival autograft. To date the most common surgical methods of attaching conjunctival autografts to the sclera are through suturing or fibrin glue...

Negative pressure wound therapy (NPWT) is widely used to treat many types of complex wounds, and the advent of the instillation and dwell time (NPWTi-d) technique has enhanced this system with the addition of automated treatment with topical solutions. In the field of vascular surgery, NPWT is utilized to help close wounds over underlying grafts; however keeping these wounds free of infection and avoiding large reoperation when infection occurs remains a challenge. In this case report we present a patient who required acute intervention for limb ischemia, with a large wound created in the groin for anastomosis of a prosthetic graft bypass...

Katharina Frentzel, Harun Badakhshi
PURPOSE: To prevent a fatal transfusion-associated graft-versus-host disease, it is recommended to irradiate transfusion blood and blood components with ionizing radiation. Using x-rays from a linear accelerator of the radiotherapy department is an accepted alternative to gamma irradiation devices of the blood bank and to the orthovoltage units that are replacing the gamma irradiators today. However, the use of high energy x-rays may carry a potential risk of induced radioactivity. The objective of this study was to investigate the effect of two different energy levels, 6 and 18 MV, which are executed in routine clinical settings...

BACKGROUND: Non-adherence to medication is a well-studied and known cause of late allograft loss, but it is difficult to measure and prospectively monitor. The aim of this study was to assess if appointment non-adherence was correlated with medication non-adherence and a predictor of graft outcomes. METHODS: This was a longitudinal cohort study that used the National United States Renal Data System and veterans affairs health records data with time-to-event analyses conducted to assess the impact on graft and patient survival...

BACKGROUND: Approximately fifty percent of patients with acute myeloid leukemia can be cured with current therapeutic strategies which include, standard dose chemotherapy for patients at standard risk of relapse as assessed by cytogenetic and molecular analysis, or high-dose chemotherapy with allogeneic hematopoietic stem cell transplant for high-risk patients. Despite allogeneic hematopoietic stem cell transplant about 25% of patients still succumb to disease relapse, therefore, novel strategies are needed to improve the outcome of patients with acute myeloid leukemia...

Several groups have reported extended survival of genetically-engineered pig organs in nonhuman primates, varying from almost 10 months for life-supporting kidney grafts and >2 years for nonlife-supporting heart grafts to less than 1 month for life-supporting liver and lung grafts. We have attempted to define groups of patients who may not have an option to wait for an allograft. These include kidney, heart, and lung candidates who are highly-allosensitized. In addition, some kidney candidates (who have previously lost at least 2 allografts from rapid recurrence of native kidney disease) have a high risk of further recurrence and will not be offered a repeat allotransplant...

BACKGROUND: Patients with severely reduced left-ventricular ejection fraction carry a high risk of morbidity and mortality after cardiac surgery. Levosimendan can be used prophylactically in these patients having shown positive effects on short-term outcome. However, effects on long-term outcome and patient subgroups benefiting the most are unknown. We aim to address these topics with real-life data from our clinical practice. METHODS: Two hundred eigthy eight patients with preoperative LVEF ≤ 35% underwent cardiac surgery with cardiopulmonary bypass between 2009 and 2013...
