A Novel Hybrid Silk Fibroin/Polyurethane Arteriovenous Graft for Hemodialysis: Proof-of-Concept Animal Study in an Ovine Model.

To solve the problem of vascular access failure, a novel semi-degradable hybrid vascular graft, manufactured by electrospinning using silk fibroin and polyurethane (Silkothane), has been previously developed and characterized in vitro. This proof-of-concept animal study aims at evaluating the performances of Silkothane grafts in a sheep model of arteriovenous shunt, in terms of patency and short-term remodeling. Nine Silkothane grafts are implanted between the common carotid artery and the external jugular vein of nine sheep, examined by palpation three times per week, by echo-color Doppler every two weeks, and euthanized at 30, 60, and 90 days (N = 3 per group).

Establishing an Anatomic Pathology Laboratory at Cleveland Clinic Abu Dhabi.

Context: - The Department of Anatomic Pathology is a division of the Pathology & Laboratory Medicine Institute at Cleveland Clinic Abu Dhabi. The hospital offers the same model of care as its US-based counterpart the Cleveland Clinic, established in 1921 in Cleveland, Ohio. Pathology services at Cleveland Clinic are internationally acclaimed: the endeavor for Cleveland Clinic Abu Dhabi was to create a parallel facility, with the same standards in a greenfield start-up environment.

Setting Up an ePathology Service at Cleveland Clinic Abu Dhabi: Joint Collaboration With Cleveland Clinic, United States.

Context.—: The production of whole slide images is the most advanced form of digital pathology, in which a high-resolution digital scanner is used to rapidly scan glass microscope slides and produce a computer-generated whole slide image that can be saved, stored in a network-attached storage device, and accessed through slide management software within the hospital domain and remotely by authorized users. Digital transformation of glass slides has revolutionized the practice of anatomic pathology by facilitating and expediting consultative services, improving clinical workflow, and becoming an indispensable tool in education and research.

Rare Aggressive Calvarial Osteoblastoma with Dural Invasion.

We report a rare case of an aggressive osteoblastoma (OB) involving the calvaria and infiltrating the dura, a finding that was not previously reported in the literature. A 50-year-old man presented with a progressive mass in the left frontoparietal skull with headaches and a six-month history of sudden mass growth. Computed tomography (CT) and magnetic resonance imaging (MRI) showed a large skull lesion with areas of hemorrhage, calcification, restricted diffusion, and enhancement.

Systematic Surface Phase Transition of Ag Thin Films by Iodine Functionalization at Room Temperature: Evolution of Optoelectronic and Texture Properties.

We show a simple room temperature surface functionalization approach using iodine vapour to control a surface phase transition from cubic silver (Ag) of thin films into wurtzite silver-iodid (β-AgI) films. A combination of surface characterization techniques (optical, electronical and structural characterization) reveal distinct physical properties of the new surface phase. We discuss the AgI thin film formation dynamics and related transformation of physical properties by determining the work-function, dielectric constant and pyroelectric behavior together with morphological and structural thin film properties such as layer thickness, grain structure and texture formation.

Substrain-specific differences in bone parameters, alpha-2-macroglobulin circulating levels, and osteonecrosis incidence in a rat model.

Osteonecrosis of the femoral head (ONFH) is a potentially devastating complication that occurs in up to 40% of young adults receiving chronic glucocorticoid (GC) therapy. Through a validated GC therapy rat model, we have previously shown that Wistar Kyoto (WK) rats exhibit a genetic susceptibility to GC-induced ONFH compared to Sasco Fischer (F344) rats. We have undertaken this study in order to investigate differences between these two strains for their bone parameters, alpha-2-macroglobulin (A2M) circulating levels and incidence of GC-induced osteonecrosis of the femoral head.

Optical nano-structuring in light-sensitive AgCl-Ag waveguide thin films: wavelength effect.

Irradiation of photosensitive thin films results in the nanostructures formation in the interaction area. Here, we investigate how the formation of nanostructures in photosensitive waveguide AgCl thin films, doped by Ag nanoparticles, can be customized by tuning the wavelength of the incident beam. We found, silver nanoparticles are pushed towards the interference pattern minima created by the interference of the incident beam with the excited TE-modes of the AgCl-Ag waveguide.

Urine cytology: does the number of atypical urothelial cells matter? A qualitative and quantitative study of 112 cases.

Introduction: This study presents a detailed and systematic morphological and quantitative analysis of urine cytology specimens in order to determine which qualitative and quantitative features are mostly associated with high-grade urothelial carcinoma (HGUCA).

Material And Methods: This study included 112 urine cytology cases with a surgical follow-up within 1 year that were originally reported as "atypical," "suspicious for HGUCA," or "positive for HGUCA." The morphological characteristics as well as the number of abnormal cells were correlated with a diagnosis of HGUCA on follow-up biopsy.

Penile metastasis from rectal cancer by PET/CT.

It is extremely rare for rectal tumors to metastasize to the penis, and when it occurs, it is associated with poor prognosis. The appearance of penile metastasis from rectal primary tumor on PET imaging has not been widely reported. We report a case of a 70-year-old man with previous history of treated stage III adenocarcinoma of the rectum 26 months ago.

Imaging characteristics of spindle cell lipoma and its variants.

A spindle cell lipoma (SCL) is a relatively common tumor that can be challenging to the radiologist, pathologist, or surgeon to diagnose, particularly when internal fat content is scant or absent. Although these lesions may be found at various locations, the typical presentation for this lesion is a well-circumscribed and non-aggressive subcutaneous mass in the posterior neck presenting in a middle-aged to elderly man. In this article, the typical and atypical imaging characteristics of a spindle cell lipoma (SCL) will be reviewed.

Metabolic activity measured on PET/CT correlates with clinical outcomes in patients with limb and girdle sarcomas.

Objective: To explore the relationship between metabolic activity and outcome in patients with extremity sarcomas.

Methods: Between June 2004 and December 2011, 120 patients with newly diagnosed limb and girdle sarcomas underwent FDG-PET/CT for disease staging prior to curative intent treatment. The maximum standardized uptake value (SUV(max)) was measured for each primary tumor and correlated with outcome.

Necrosis on FDG PET/CT correlates with prognosis and mortality in sarcomas.

Objective: The purpose of this study was to determine if there is an association between necrosis as identified on staging (18)F-FDG PET/CT and overall survival (OS) and progression-free survival (PFS) in patients with sarcoma.

Materials And Methods: Sixty-six patients with newly diagnosed limb and girdle sarcoma underwent PET/CT at our institution between June 2004 and July 2009 for sarcoma staging before treatment with curative intent. The tumor maximum standardized up-take values (SUVmax), the presence of necrosis, and the volume of necrosis were measured for each primary tumor and correlated with follow-up data.

Oral cellular neurothekeoma.

Cellular neurothekeoma is known as a cutaneous tumor with uncertain histogenesis. Very little involvement of mucosal membrane has been reported in the literature so far. This is a case report of an intraoral lesion in a 15-years-old girl.

Primitive neuroectodermal tumor (PNET) as somatic-type malignancy arising from an extragonadal germ-cell tumor: clinical, pathological and molecular features of a case.

We report a rare case of a 34-year-old man with a right axillary mass. Ten years previously, he had been diagnosed with a right scapular nonseminomatous germ-cell tumor consisting of teratoma, completely resected without any further treatment. Presently he was found to have a metastatic malignant small round cell tumor consistent with a secondary somatic malignancy arising in the background of nonseminomatous germ-cell tumor, teratoma, yolk sac tumor, and primitive neuroectodermal tumor with distinct chromosome 22 translocation.

Soft tissue tumors of the anorectum: rare, complex and misunderstood.

Anorectal soft tissue tumors are uncommon and often present both diagnostic and therapeutic challenges. Although many of these tumors are identified with imaging performed for unrelated reasons, most present with nonspecific symptoms that can lead to a delay in diagnosis. Historically, radical surgery (abdominoperineal resection) has been the mainstay of treatment for both benign and malignant anorectal soft tissue tumors.

Urinary bladder leiomyosarcoma: staging with 18F-FDG PET/CT.

A 28-year-old woman with a history of prior bilateral retinoblastoma presented with general fatigue, anemia, and a urinary bladder mass seen on abdominal ultrasound and CT. She was referred for a staging 18F-FDG PET/CT, which showed an intensely FDG-avid bladder mass that was biopsied to reveal a leiomyosarcoma, with no evidence of metastases, which guided her management. 18F-FDG PET/CT is routinely used in the evaluation of leiomyosarcomas; however, its use in the staging of a leiomyosarcoma of the urinary bladder has not been previously described in the literature.

Transoral endoscopic resection of esophageal liposarcoma.

A 63-year-old man presented with a 1-month history of dysphagia. Endoscopy showed the patient had a mass in the cervical esophagus. Multiple biopsy specimens were taken, which were inconclusive for a diagnosis.

Long-term remission after autologous stem-cell transplantation for relapsed histiocytic sarcoma.

Histiocytic sarcoma is diagnosed according to established criteria. However, treatment is controversial: although lymphoma chemotherapy regimens are often used, their impact on the natural history of the disease is unclear. Here, we report a disease-free survival of 2 years after autologous stem-cell transplantation in a patient with relapsed histiocytic sarcoma.

Primary perivascular epithelioid cell neoplasm (PEComa) of bone: report of two cases and review of the literature.

Primary perivascular epithelioid cell neoplasms (PEComas) of bone are rare mesenchymal tumors. Histologically, they are composed predominantly of perivascular epithelioid cells and have the capacity to metastasize. PEComas have been reported within intra-abdominal and intra-pelvic organs.
