Metal alloys are frequently used as implant materials in veterinary medicine. Recent studies suggest that many alloys induce both local and systemic inflammatory responses. In this study, 37 rhesus macaques with long-term skull-anchored percutaneous titanium alloy implants (duration, 0 to 14 y) were evaluated for changes in their hematology, coagulation, and serum chemistry profiles. Negative controls (n = 28) did not have implants. Macaques with implants had higher plasma D-dimer and lower antithrombin III concentrations than nonimplanted animals...

Percutaneous transthoracic needle biopsies (PTNB) are widely used for the diagnosis of a peripheral pulmonary nodules, but the risk of pleural recurrence in lung cancer patients remains undetermined. Our meta-analysis aims to answer the question whether PTNB strategy increases the risk of recurrence. PubMed, EMBASE, The Cochrane Library, and China National Knowledge Infrastructure (CNKI) were searched from inception to January 9, 2016. A total of 1242 patients from 5 studies were included. The results showed that PTNB does not increase risk of total recurrence (Odds Ratio,0...

PURPOSE: To compare the accuracy and required time for image fusion of real-time ultrasound (US) with pre-procedural magnetic resonance (MR) images between positioning auto-registration and manual registration for percutaneous radiofrequency ablation or biopsy of hepatic lesions. METHODS: This prospective study was approved by the institutional review board, and all patients gave written informed consent. Twenty-two patients (male/female, n = 18/n = 4; age, 61...

BACKGROUND: Feeding higher-energy prepartum is a common practice in the dairy industry. However, recent data underscore how it could reduce performance, deepen negative energy balance, and augment inflammation and oxidative stress in fresh cows. We tested the effectiveness of rumen-protected methionine in preventing the negative effect of feeding a higher-energy prepartum. Multiparous Holstein cows were fed a control lower-energy diet (CON, 1.24 Mcal/kg DM; high-straw) during the whole dry period (~50 d), or were switched to a higher-energy (OVE, 1...

BACKGROUND: Renal biopsy is an important method for diagnosis of renal parenchymal abnormalities. Here, we compare the effectiveness and complications of percutaneous ultrasound-guided renal biopsy using axial vs. sagittal probe locations. METHODS: In a cross-sectional survey, in 2012, patients with a nephrologist order were biopsied by a radiology resident. Renal biopsy was done on 15 patients using axial (A group) and the same number of biopsies done with sagittal probe location (S group)...

PURPOSE: To investigate whether an autologous intraparenchymal blood patch (IPB) reduces the rate of pneumothorax-related complications associated with computed tomography (CT)-guided lung biopsies. MATERIALS AND METHODS: This study included 834 patients: 482 who received an IPB and 352 who did not. Retrospective review was performed of all CT-guided lung biopsies performed at a single institution between August 2006 and September 2013. Patients were excluded if no aerated lung was crossed...

PURPOSE: To determine if renal mass biopsy should be performed before or during the ablation procedure with emphasis on complications and rate of ablation for renal cell carcinomas (RCC), benign tumors, and small renal masses without a histologic diagnosis. METHODS: This HIPAA-compliant, single-center retrospective study was performed under a waiver of informed consent from the institutional review board. Two hundred eighty-four consecutive patients with a small renal mass (≤4...

The case of a 70-year-old woman with progressive renal cell carcinoma (RCC) metastatic invasion of a L3 vertebral hemangioma treated by dual percutaneous radiofrequency ablation (RFA) and vertebroplasty is reported. The patient was surgically treated for RCC in 2001. Chemotherapy and immunotherapy were introduced in 2013 for ovarian, bladder and cerebral metastatic disease. An asymptomatic L3 benign hemangioma was noticed at this time. One-year CT and MRI follow-up studies demonstrated a nodular isolated soft tissue lesion involving the anterior edge of the hemangioma...

OBJECTIVE: Due to minimal tissue violation in percutaneous core needle biopsy (CNB), in contrast to open biopsy, the risk of tumor seeding and subsequent local recurrence (LR) along the biopsy tract remains unclear in extremity soft tissue sarcoma (STS). This study sought to examine the association of CNB tract resection on LR in a large STS institutional database. MATERIALS AND METHODS: After a retrospective review of the 116 patients who underwent CNB prior to surgery for previously untreated non-metastatic extremity STS, 36 patients who did not have CNB tracts resected (CNB-NR) were matched with 36 who had CNB tracts resected (CNB-R) for the factors that are known to affect LR...

Multiple myeloma is characterised by the neoplastic proliferation of a single clone of plasma cells producing a monoclonal immunoglobulin. This clone of plasma cells proliferates in the bone marrow, resulting in extensive skeletal destruction with osteolytic lesions, osteopenia and pathological fractures. Additional disease-related complications include hypercalcaemia, renal insufficiency, anaemia and infection. We present the case of a 64-year-old woman presenting with rapid onset, painful distal symmetrical lower limb weakness and an acute kidney injury...

The aim of this study was to determine the safety, effectiveness, complications, and pathological impact of TJLB. METHODS: This cross-sectional study was conducted on 24 consecutive patients, undergoing TJLB at Imam Reza Hospital, affiliated to Mashhad University of Medical Sciences, from April 2010 to March 2011...

PURPOSE: Determine if deposition characteristics of ferumoxytol (FMX) iron nanoparticles in tumors, identified by quantitative MRI, may predict tumor lesion response to nanoliposomal irinotecan (nal-IRI). EXPERIMENTAL DESIGN: Eligible patients with previously treated solid tumors had FMX-MRI scans before and following (1, 24, and 72 hours) FMX injection. After MRI acquisition, R2* signal was used to calculate FMX levels in plasma, reference tissue and tumor lesions by comparison with a phantom-based standard curve...

PURPOSE: Percutaneous biopsy obtained from a single location is prone to sampling error in large heterogeneous renal masses, leading to nondiagnostic results or failure to detect poor prognostic features. We evaluated the accuracy of percutaneous biopsy for large renal masses using a modified multi-quadrant technique vs. a standard biopsy technique. MATERIALS AND METHODS: Clinical and pathological data for all patients with cT2 or greater renal masses who underwent percutaneous biopsy from 2009 to 2014 were reviewed...

OBJECTIVE Medically refractory spasticity and dystonia are often alleviated with intrathecal baclofen (ITB) administration through an indwelling catheter inserted in the lumbar spine. In patients with cerebral palsy, however, there is a high incidence of concomitant neuromuscular scoliosis. ITB placement may be technically challenging in those who have severe spinal deformity or who have undergone prior instrumented thoracolumbar fusion. Although prior reports have described drilling through the lumbar fusion mass with a high-speed bur, as well as IT catheter implantation at the foramen magnum or cervical spine, these approaches have notable limitations...

BACKGROUND: Immunocomplex capture fluorescence analysis (ICFA) is an attractive method to detect donor-specific anti-HLA antibodies (DSA) and HLA antigen complexes. Currently, antibody-mediated rejection (AMR) due to DSA is usually diagnosed by C4d deposition and serological DSA detection. Conversely, there is a discrepancy between these findings frequently. Thereupon, our graft ICFA technique may contribute to establish the diagnosis of AMR. METHODS: Graft samples were obtained by a percutaneous needle biopsy...

A 70-year-old-man, whose chief complaint was epigastric pain, was referred to our hospital and diagnosed with advanced gastric cancer with multiple liver metastases. Gastrointestinal endoscopy showed a tumor on the anterior wall of the gastric lower body. Histologically, biopsy specimens indicated adenocarcinoma, and immunohistochemistry showed positive expression of HER2(3+). Chest and abdominal computed tomography showed multiple liver metastases and lymph node metastases. We started chemotherapy with capecitabine, cisplatin, and trastuzumab...
