Acute Post-Operative Pain Management: Preventing Overuse Of Opioids, Alison Hirsch
Acute Post-Operative Pain Management: Preventing Overuse Of Opioids, Alison Hirsch
Theses and Graduate Projects
Background: Surgical pain management with opioids is common. The use of multimodal analgesia has been proposed in order to provide opioid-sparing regimens and improve pain control post-operatively. Inadequate control of surgical pain can lead to development of chronic pain. Furthermore, studies have linked acute surgical opioid use to increased risk of long-term use. Long-term opioid use has undesirable, life-altering consequences, including physical dependence and addiction which may lead to overdose or death. Use of a variety of medications in the operative setting can lead to synergistic or additive effects on pain control, thus decreasing post-operative opioid consumption.
Methods: A literature …

Role Of Extent Of Resection On Quality Of Life In Patients With Newly Diagnosed Gbm, Usama Khalid Choudry, Huzaifa Ismail Shaikh, Areeba Nisar, Saad Akhtar Khan, Muhammad Shahzad Shamim
Section of Orthopaedic Surgery
Glioblastomas known for their adverse outcomes are most reportedly managed by surgical resection. Studies on the impact of (Extent of Resection) EOR against Quality of Life (QOL) are very limited. We have collected data from recent studies in this review to extract a general consensus among the neurosurgeons regarding the EOR. Key parameters like functional independence, neurocognitive improvements and global health status have been explored in the context of QOL. The currently available data suggests that an increased EOR may help improve QOL in GBM patients. With the help of recent advancements it may be possible to attain a better …

Primary Total Hip Arthroplasty: Staying Out Of Trouble Intraoperatively, Shahryar Noordin, Riaz Hussain Lakdawala, Bassam A. Masri
Section of Orthopaedic Surgery
Total hip Arthroplasty is one of the most successful and commonly performed procedures in Orthopaedic Surgery. Meticulous preoperative planning allows to surgeon anticipate potential problems to reduce postoperative complications and optimize patient outcomes. Currently, the posterior approach is the most common approach utilized in the United States. In order to prevent errors in stem version, especially with cementless fixation, the entry point should be posterior, and the initial entry point should be aligned in the correct anteversion as this will determine the ultimate version of the stem. Preoperative evaluation should asses for true and apparent lengths. For successful osseointegration of …

Abnormal T Cell Frequencies, Including Cytomegalovirus-Associated Expansions, Distinguish Seroconverted Subjects At Risk For Type 1 Diabetes, Robert Z. Harms, Kristina M. Lorenzo-Arteaga, Katie R. Ostlund, Victoria B. Smith, Lynette M. Smith, Peter Gottlieb, Nora Sarvetnick
Journal Articles: Surgery
We analyzed T cell subsets from cryopreserved PBMC obtained from the TrialNet Pathway to Prevention archives. We compared subjects who had previously seroconverted for one or more autoantibodies with non-seroconverted, autoantibody negative individuals. We observed a reduced frequency of MAIT cells among seroconverted subjects. Seroconverted subjects also possessed decreased frequencies of CCR4-expressing CD4 T cells, including a regulatory-like subset. Interestingly, we found an elevation of CD57+, CD28-, CD127-, CD27- CD8 T cells (SLEC) among seroconverted subjects that was most pronounced among those that progressed to disease. The frequency of these SLEC was strongly correlated with CMV IgG abundance among seroconverted …

Prognostic Value Of 1p/19q Chromosomal Codeletion In Patients With Oligodendroglioma, Altaf Ali Laghari, Muhammad Usman Khalid, Namra Qadeer, Muhammad Shahzad Shamim
Section of Neurosurgery
Oligodendrogliomas are common intra-axial primary brain tumours, and carry special significance due to several key features, which when present provide better prognosis compared to other intra-axial tumours. One of these features is presence of 1p/19q chromosomal codeletion that seems to not only be a marker of better prognosis but also signifies better response to chemotherapy. Herein the authors review the literature for evidence of the prognostic value of 1p/19q codeletion in OD.

Advances in the surgical management of the axilla in patients treated with neoadjuvant chemotherapy, especially those with node positive disease at diagnosis, have led to changes in practice and more judicious use of axillary lymph node dissection that may minimize morbidity from surgery. However, there is still significant confusion about how to optimally manage the axilla, resulting in variation among practices. From the viewpoint of drug development, assessment of response to neoadjuvant chemotherapy remains paramount and appropriate assessment of residual disease-the primary endpoint of many drug therapy trials in the neoadjuvant setting-is critical. Therefore decreasing the variability, especially in a …

FDA-approved BRAF inhibitors produce high response rates and improve overall survival in patients with BRAF V600E/K-mutant melanoma, but are linked to pathologies associated with paradoxical ERK1/2 activation in wild-type BRAF cells. To overcome this limitation, a next-generation paradox-breaking RAF inhibitor (PLX8394) has been designed. Here, we show that by using a quantitative reporter assay, PLX8394 rapidly suppressed ERK1/2 reporter activity and growth of mutant BRAF melanoma xenografts. Ex vivo treatment of xenografts and use of a patient-derived explant system (PDeX) revealed that PLX8394 suppressed ERK1/2 signaling and elicited apoptosis more effectively than the FDA-approved BRAF inhibitor, vemurafenib. Furthermore, PLX8394 was …

Despite the growing elderly population, there is limited research specific to this demographic concerning breast reconstruction (BR). Lack of evidence-based BR recommendations in older populations may contribute to misconceptions and subsequent underutilization of BR, especially autologous BR. Patients who received either deep inferior epigastric perforator (DIEP) flap BR or tissue expander/implant (TE/I) BR by a single surgeon between July 2011 and July 2015 were surveyed postoperatively by using the psychometrically validated BREAST-Q questionnaire to determine patient satisfaction. Patients were categorized into younger and older cohorts based on median age (55 years) and further stratified based on the type of reconstruction. …

Purpose: Hemiepiphysiodesis has been widely used to correct angular deformity of long bone in immature patients. However, there is a limited knowledge about the biomechanical effect of this technique on the histopathological changes of the growth plate and the mechanism of recurrence of malformation after implant removal. We aimed to evaluate the biomechanical effect of hemiepiphysiodesis on the histopathological changes of the growth plate and the mechanism of recurrence of malformation after implant removal in Bama miniature pigs, and to explore the role of asymmetric stress during this procedure.
Methods: Eight 3-month-old male Bama miniature pigs sustained surgeries on the …
