Spontaneous isolated dissection of the iliac artery (SID-IA) is a rare vascular condition typically associated with trauma or connective tissue disorders. We present a unique case of a 39-year-old male without known risk factors or trauma history who presented with lower abdominal pain. Diagnostic imaging revealed SID-IA involving the right external iliac artery with thrombus formation.

We evaluated genotype concordance between tumor DNA and genomic DNA from blood and catalogued functional effects of somatic mutations in 21 drug response genes in 752 solid tumor patients. Using a threshold of 10% difference between tumor and blood DNA variant allele fraction (VAF), concordance for heterogenous genotype calls was 78% and increased to 97.

Most of these problems are temporary, but in some cases, nerve paresthesia may become permanent and lead to functional problems.
Aims And Objectives: This study aims at measuring the clinical severity of pain, swelling, muscle trismus, infection, dry socket and any nerve injury-related paresthesia after surgical removal of M3.
Purpose: Irinotecan/5-fluorouracil (5-FU; FOLFIRI) or oxaliplatin/5-FU (FOLFOX), combined with bevacizumab or cetuximab, are approved, first-line treatments for metastatic colorectal cancer (mCRC). We aimed at identifying germline variants associated with survival in patients with mCRC treated with these regimens in Cancer and Leukemia Group B/SWOG 80405.
Experimental Design: Patients with mCRC receiving either FOLFOX or FOLFIRI were randomized to either cetuximab or bevacizumab.
Atypical hyperplasia/endometrial intraepithelial neoplasia is an accepted precursor to endometrioid-type endometrial carcinoma. Mismatch repair-deficient endometrial carcinomas are also known to be a biologically and clinically distinct subset of tumors. However, the development of microsatellite instability in endometrial carcinogenesis has not yet been evaluated by novel next-generation sequencing-based methods.

To add to emerging data on molecular alterations present in these tumors, we analyzed our institution's cohort of IBD-CRCs. CRCs resected from patients with IBD underwent molecular analysis via a 50-gene hot-spot solid tumor panel (OncoScreen ST2.

Microscopic examination of hematoxylin and eosin-stained sections reveals this entity to be well-circumscribed with tubulopapillary growth of cells with clear cytoplasm in a background of leiomyomatous stroma. Herein we describe the genetic features of 15 University of Chicago Medical Center archived cases with hematoxylin and eosin histology matching the provisional diagnosis.

Our institution has included massively parallel sequencing technology in the diagnostic work-up of all gliomas since January 2016. The utilized platform successfully identifies copy number variations, individual gene mutations, small insertions and deletions, and selected gene fusions.

Herein, we have generated a publicly available, highly flexible tool, in silico Mutator (insiM), to introduce point mutations, insertions, deletions, and duplications of any size into real data sets of amplicon-based or hybrid-capture NGS assays. insiM accepts an alignment file along with target territory and produces paired-end FASTQ files containing specified mutations via modification of original sequencing reads.

As the scale of an NGS laboratory grows, management of these assays requires organizing large amounts of information, including patient data, laboratory processes, genomic data, as well as variant interpretation and reporting. Although several Laboratory Information Systems and/or Laboratory Information Management Systems are commercially available, they may not meet all of the needs of a given laboratory, in addition to being frequently cost-prohibitive.

Separately, RCCs found in patients with tuberous sclerosis complex (TSC) have recently been categorized into 3 morphologic groups: RCC with a tubulopapillary architecture separated by smooth muscle stroma, chromophobe-like, and eosinophilic-microcytic type. The third classification has been identified in ∼11% of TSC-associated RCC and have histology identical to ESC RCCs.

Because these panels include genes associated with hereditary hematopoietic malignancies (HHMs), we hypothesized that these panels could identify pathogenic germ line variants in malignant cells, thereby identifying patients at risk for HHMs. In total, pathogenic or likely pathogenic variants in , , , , , , or were identified in 74 (21%) of 360 patients.

Commercial modified oil and indigenous natural fatty acids comprised the oily phase in developing lipidic formulation of β-Artemether and Lumefantrine. The developed system was characterized for mean globule size, stability by freeze thaw cycles, and birefringence.

For this investigation, microemulsion (ME), solid lipid nanoparticles (SLNs), and nanostructured lipid carriers (NLCs) were formulated and characterized for physicochemical parameters. The pseudo-ternary phase diagrams for microemulsion region were developed using generally recognized as safe (GRAS) excipients.

Methods: The study compared the in vivo pharmacodynamic efficacy of ARM NLC with C-AST in a murine model. For this study, the Peters 4 day suppressive test was adopted.
The present investigation involved preparation of hydrogel nanoparticles using a combination of hydroxyl propyl methyl cellulose and polyvinyl pyrrolidone. The objective was to exploit the size and hydrophilic nature of the formulated nanocarriers to enhance absorption and prolong the rapid clearance of curcumin due to possible evasion of the reticulo-endothelial system. Reproducible nanoparticles of size around 100 nm, a fairly narrow distribution and encapsulation efficiency of 72%, were produced by the solvent emulsion-evaporation technique.

Although coronary artery aneurysms occur in Kawasaki disease, giant aneurysms are rare. We report a very large coronary artery aneurysm, measuring 25 mm and involving left anterior descending artery, in a 2-year-old child with Kawasaki disease. The challenges in management of such a patient have been highlighted.
