House Staff Quality Improvement and Patient Safety Conference (2016-2019)
- The Joint Commission has linked communication failure as a root cause for a majority of sentinel events.
- The “I-PASS” system is a hand-off mnemonic that has been shown to decrease medical errors, prevent adverse events, and improve communication.
- Multiple Jefferson residency programs have adopted I-PASS training over the last year to standardize sign-outs between treatment teams and departments.
- Radiology residents also participate in hand-offs with other departments, especially in cases of adverse patient reactions that occur within radiology (ie: allergic reaction, seizure, contrast extravasation). In addition, radiology residents also participate in hand offs between daytime and overnight teams ...
Varicosities Affecting The Lower Limb Veins Consequent To A Unique Variant Drainage Pattern Of The Small Saphenous Vein, 2018 University of Massachusetts Medical School
Varicosities Affecting The Lower Limb Veins Consequent To A Unique Variant Drainage Pattern Of The Small Saphenous Vein, Shauna Mary Rice, Elke Sarah Schipani, Ana Maleesa Rae Santos, Katherine Anais Sadaniantz, Prithwijit Roychowdhury, Eustathia Lela Giannaris, Manas Das
We report varicosities affecting the right deep femoral vein and the right femoral vein consequent to a unique unilateral variation in the course of the small saphenous vein. The right small saphenous vein, instead of draining into the popliteal vein at the popliteal fossa, expanded considerably in girth and thickness and continued as the deep femoral vein. The deep femoral vein then pierced the adductor magnus muscle, appeared in the anterior compartment, and joined the femoral vein. Four centimeters distal to this junction, a two-centimeter long varicosity in the deep femoral vein was noted. There was also a one-centimeter long ...

Department of Radiology
We present a case of a 14-year-old girl who was diagnosed with Burkitt lymphoma in 2014. She was managed with chemotherapy and remained in remission for 3 years. On her surveillance imaging in 2017, a left-sided renal neoplastic mass was incidentally discovered. She underwent nephrectomy and pathology of the resected specimen revealed small cell tumour of the kidney with features favouring renal Ewing sarcoma/primitive neuroectodermal tumour. Molecular genetic analysis by fluorescence in situ hybridisation was performed which showed translocation of 22q12, thereby confirming the diagnosis. This is a rare secondary malignancy and an unusual association. This case highlights the ...
Ultrasound-Guided Introital Drainage Of Pyometrocolpos, 2018 George Washington University
Ultrasound-Guided Introital Drainage Of Pyometrocolpos, I Kim, Ranjith Vellody, Hans G. Pohl, Karun Sharma, Kabir Yadav
Radiology Faculty Publications
Pyometrocolpos can be caused by congenital malformations such as distal vaginal atresia and imperforate hymen. Patients usually present with obstructive urinary tract infections, acute kidney injury, or sepsis. Percutaneous drainage of the infected fluid can help treat the patient; however, recurrence is of concern. In this case report, we present a case of a child with recurrent pyometrocolpos due to distal vaginal atresia despite initial percutaneous drainage. To our knowledge, this is the first report of ultrasound-guided introital drainage of pyometrocolpos with relief of symptoms obviating the need for repeat drainage or immediate surgery. © 2017

Enterocutaneous fistulas (ECFs) can be one of the complications found after surgical intervention for rectal cancer. Interventional modalities consisting of surgical, endoscopic, and radiological methods are often implemented to treat postoperative symptomatic complications. We present the case of 61-year-old Caucasian man who presented to us with a recent diagnosis of rectal cancer that had invaded the levators as well as anteriorly into the prostate, and who underwent low anterior resection with a diverting loop ileostomy. The patient was found to have a persistent presacral abscess due to an ECF tract. This case highlights the off-label use of ethylene-vinyl alcohol copolymer ...
Unicameral Bone Cysts: Current Concepts, 2018 Aga Khan University
Unicameral Bone Cysts: Current Concepts, Shahryar Noordin, Salim Allana, Masood Umer, Mujahid Jamil, Kiran Hilal, Nasir Ud Din
Section of Orthopaedic Surgery
Unicameral bone cysts (UBC) or simple/solitary bone cysts are benign fluid filled cavities that enlarge over time, resulting in thinning of the bone. Usually these cysts are reported in the metaphyseal areas of long bones with open physes. 85% of UBCs occur almost exclusively in children and adolescents. UBCs are more aggressive in the first decade of life and correspondingly the recurrence rate for these patients is four times that for adolescents. The proximal humerus and femur account for almost 90% of these cases. UBCs are classified as active when they are within 1 cm of the physis and ...
Defining The Radioresponse Of Mossy Cells, 2018 California State University, San Bernardino
Defining The Radioresponse Of Mossy Cells, Devon Ivy
Electronic Theses, Projects, and Dissertations
Clinical radiotherapy is used to treat a variety of brain tumors within the central nervous system. While effective, it can result in progressive and debilitating cognitive impairment that can diminish quality of life. These impairments have been linked to hippocampal dysfunction and corresponding deficits in spatial learning and memory. Mossy cells are a major population of excitatory neurons located within the dentate hilus and highly involved in hippocampal circuitry. They play critical roles in spatial navigation, neurogenesis, memory, and are particularly vulnerable to a variety of neurotoxic insults. However, their sensitivity to ionizing radiation has yet to be investigated in ...

Progress in clinical development of magnetic resonance imaging (MRI) substrate-sensors of enzymatic activity has been slow partly due to the lack of human efficacy data. We report here a strategy that may serve as a shortcut from bench to bedside. We tested ultra high-resolution 7T MRI (microMRI) of human surgical histology sections in a 3-year IRB approved, HIPAA compliant study of surgically clipped brain aneurysms. microMRI was used for assessing the efficacy of MRI substrate-sensors that detect myeloperoxidase activity in inflammation. The efficacy of Gd-5HT-DOTAGA, a novel myeloperoxidase (MPO) imaging agent synthesized by using a highly stable gadolinium (III) chelate ...

Adenomyoepithelioma of the breast is a rare tumor characterized by epithelial-myoepithelial differentiation, whose genetic underpinning is largely unknown. Here we show through whole-exome and targeted massively parallel sequencing analysis that whilst estrogen receptor (ER)-positive adenomyoepitheliomas display PIK3CA or AKT1 activating mutations, ER-negative adenomyoepitheliomas harbor highly recurrent codon Q61 HRAS hotspot mutations, which co-occur with PIK3CA or PIK3R1 mutations. In two- and three-dimensional cell culture models, forced expression of HRAS
Rapid Assessment Of Adults With Traumatic Brain Injuries, 2018 University of San Diego
Rapid Assessment Of Adults With Traumatic Brain Injuries, Pedro Colio
Doctor of Nursing Practice Final Manuscripts
The aim of this evidence-based project was to improve the medical screening process, enhance medical decision-making, and standardized the utilization of an adult traumatic brain injury neuroimaging guideline among advanced practice providers in a rural emergency department. Neuroimaging, specifically computed tomography (CT) scans, help to identify life-threatening intracranial injuries when clinically appropriate. The literature supports the utilization of neuroimaging guidelines, clinical exam, and provider expertise when identifying the need for a head CT scan. Although head CT scans are clinically useful, they increase healthcare costs and pose potential cancer risks from radiation exposure. Eight advanced practice providers (i.e., nurse ...

Effect Of Trinucleotide Repeats In The Huntington's Gene On Intelligence, Jessica K Lee, Amy Conrad, Eric Epping, Kathy Mathews, Vincent Magnotta, Jeffrey D Dawson, Peg Nopoulos
Stead Family Department of Pediatrics Publications
BACKGROUND: Huntington's Disease (HD) is caused by an abnormality in the HTT gene. This gene includes trinucleotide repeats ranging from 10 to 35, and when expanded beyond 39, causes HD. We previously reported that CAG repeats in the normal range had a direct and beneficial effect on brain development with higher repeats being associated with higher cognitive function. The current study now expands this line of inquiry to evaluate the effects of CAG repeat throughout the entire spectrum of repeats from 15 to 58.
METHODS: We evaluated brain function in children ages 6-18 years old. DNA samples were processed ...
Lumbar Artery Pseudoaneurysm Following Renal Biopsy., 2018 Aga Khan University
Lumbar Artery Pseudoaneurysm Following Renal Biopsy., Basit Salam, Kumail Khandwala
Department of Radiology
Lumbar artery pseudoaneurysms have previously been described as rare iatrogenic complications following percutaneous interventional procedures involving the flanks. We describe a case of a 71-year-old man who became unstable and dropped 3 grams of hemoglobin within 24 hours following renal biopsy. A post-biopsy hemorrhage was suspected, and a pseudoaneurysm of his second right lumbar (L2) artery was found on computed tomography angiogram (CTA). Successful coil embolization was performed in the right L2 artery. This case discusses the diagnostic and therapeutic challenges of this unusual complication as well as the anatomical and technical factors involved in the embolization of the lumbar ...
A Microtubule-Dynein Tethering Complex Regulates The Axonemal Inner Dynein F (I1), 2018 University of Yamanashi, Japan
A Microtubule-Dynein Tethering Complex Regulates The Axonemal Inner Dynein F (I1), Tomohiro Kubo, Yuqing Hou, Deborah A. Cochran, George B. Witman, Toshiyuki Oda
Motility of cilia/flagella is generated by a coordinated activity of thousands of dyneins. Inner dynein arms (IDAs) are particularly important for the formation of ciliary/flagellar waveforms, but the molecular mechanism of IDA regulation is poorly understood. Here, we show using cryo-electron tomography and biochemical analyses of Chlamydomonas flagella that a conserved protein FAP44 forms a complex that tethers IDA f (I1 dynein) head domains to the A-tubule of the axonemal outer doublet microtubule. In wild-type flagella, IDA f showed little nucleotide-dependent movement except for a tilt in the fbeta head perpendicular to the microtubule-sliding direction. In the absence ...

BACKGROUND: Hypoxia is associated with a poor prognosis in prostate cancer. This work aimed to derive and validate a hypoxia-related mRNA signature for localized prostate cancer.
METHOD: Hypoxia genes were identified in vitro via RNA-sequencing and combined with in vivo gene co-expression analysis to generate a signature. The signature was independently validated in eleven prostate cancer cohorts and a bladder cancer phase III randomized trial of radiotherapy alone or with carbogen and nicotinamide (CON).
RESULTS: A 28-gene signature was derived. Patients with high signature scores had poorer biochemical recurrence free survivals in six of eight independent cohorts of prostatectomy-treated patients ...
Development Of 3d-Printed Patient Specific Bolus For Clinical Use In Total Scalp Irradiation, 2018 The University of Texas M D Anderson Cancer Center UTHealth Graduate School of Biomedical Sciences
Development Of 3d-Printed Patient Specific Bolus For Clinical Use In Total Scalp Irradiation, Garrett Baltz
The University of Texas MD Anderson Cancer Center UTHealth Graduate School of Biomedical Sciences Dissertations and Theses (Open Access)
Total scalp irradiation (TSI) is a specialized radiation therapy technique that aims to deliver a uniform dose to the entire scalp. Original electron-based TSI techniques had limited homogeneity due to hot and cold spots created at field junctions due to the multiple matched fields that were required to treat the entire scalp. The transition to photon volumetric-modulated arc therapy based TSI techniques has improved homogeneity, to the point where non-conformal bolus is now a limiting factor. Bolus is required to build-up full dose to the scalp surface in total scalp irradiation. Creating bolus that is conformal to the scalp is ...
