Targeted Therapies For Advanced Non-Small Cell Lung Cancer, Xiaojuan Ai, Xialing Guo, Jun Wang, Andreea L Stancu, Patrick M N Joslin, Dianzheng Zhang, Shudong Zhu

PCOM Scholarly Papers

Lung cancer is a serious health problem and the leading cause of cancer death worldwide, due to its high incidence and mortality. 85% of lung cancers are represented by the non-small cell lung cancer (NSCLC). Traditional chemotherapy has been the main treatment option in NSCLC. However, it is often associated with limited efficacy and overall poor patient survival. In recent years, molecular targeting has achieved great progress in therapeutic treatment of cancer and plays a crucial role in the current clinical treatment of NSCLC, due to enhanced efficacy on cancer tissues and reduced toxicity for normal tissues. In this review, …

Nuclear receptor coactivator 1 (NCOA1) plays crucial roles in the regulation of gene expression mediated by a wide spectrum of steroid receptors such as androgen receptor (AR), estrogen receptor α (ER α), and estrogen receptor β (ER β). Therefore, dysregulations of NCOA1 have been found in a variety of cancer types. However, the clinical relevance and the functional roles of NCOA1 in human esophageal squamous cell carcinoma (ESCC) are less known. We found in this study that elevated levels of NCOA1 protein and/or mRNA as well as amplification of the NCOA1 gene occur in human ESCC. Elevated levels of NCOA1 …

Management Of Enophthalmos From Silent Sinus Syndrome With A Customized Orbital Implant, Jason E. Cohn, Mofiyinfolu Sokoya, Mohammad Hararah, Sameep Kadakia, Yadranko Ducic

Otolaryngology (ENT) Resident Research

Background We describe the surgical treatment of silent sinus syndrome, a disease characterized by progressive enophthalmos and hypoglobus due to orbital floor collapse with opacification of the maxillary sinus, in the presence of chronic maxillary sinusitis.

Methods Case study of a 55-year-old male with persistent diplopia secondary to left-sided esotropia and enophthalmos from chronic maxillary sinusitis.

Results Two stage procedure to treat the sinonasal and orbital symptoms, which include endoscopic sinus surgery to treat the underlying the ostial obstruction along with decompression of maxillary sinus. Then, reconstruction of the orbital floor with a customized implant.

Conclusions Though the treatment of …

Holmium Laser For Endoscopic Treatment Of Benign Tracheal Stenosis, D J. Verret, Arneya Jategaonkar, Samuel Helman, Sameep Kadakia, Arash Bahrami, Eli Gordin, Yadranko Ducic

Otolaryngology (ENT) Resident Research

Introduction Laryngotracheal stenosis is a difficult problem with varied etiology and various treatment options. The holmium laser represents another tool for the treatment of benign tracheal stenosis.

Objectives To determine the utility of holmium laser treatment for benign tracheal stenosis with regards to safety and efficacy.

Methods This was a retrospective case study examining patients with benign tracheal stenosis from 1998–2016 who underwent holmium laser treatment. Determining the safety of this procedure was the primary goal, and complications were monitored as a surrogate of safety.

Results A total of 123 patients who underwent holmium laser treatment for benign tracheal stenosis …

Intraoperative Femoral Head Dislodgement During Total Hip Arthroplasty: A Report Of Four Cases, Ahmed Siddiqi, Carl T. Talmo, James V. Bono

Orthopedic Surgery Resident Research

Dislodgment of trial femoral heads and migration into the pelvis during total hip arthroplasty is a rarely reported complication with limited published cases. There are three primary mechanisms of femoral head separation: dislodgement during reduction attempt, disassociation from anterior dislocation while assessing anterior stability, and during dislocation after implant trialing. If the trial femoral migrates beyond the pelvic brim, it is safer to finish the total hip arthroplasty and address the retained object after repositioning or in a planned second procedure with a general surgeon. We recommend operative retrieval since long-term complications from retention or clinical results are lacking.

Orbital Skull Base Reconstruction With Temporalis Muscle: The Sphenoid Keyhole Technique, Mofiyinfolu Sokoya, Arash Bahrami, Jason Cohn, Sameep Kadakia, Moustafa Mourad, Yadranko Ducic

Otolaryngology (ENT) Resident Research

The temporalis flap is a common flap used in head and neck reconstruction. In this article, the authors present a new modification of the use of the temporalis muscle flap for orbital skull base reconstruction with the use of a sphenoid keyhole. This technique confers multiple advantages in reducing the arc of rotation and providing a tension-free reconstruction of the orbital skull base.

Role Of Microbes In The Development Of Alzheimer's Disease: State Of The Art - An International Symposium Presented At The 2017 Iagg Congress In San Francisco., Tamàs Fülöp, Ruth F Itzhaki, Brian J. Balin Phd, Judith Miklossy, Annelise E Barron

PCOM Scholarly Papers

This article reviews research results and ideas presented at a special symposium at the International Association of Gerontology and Geriatrics (IAGG) Congress held in July 2017 in San Francisco. Five researchers presented their results related to infection and Alzheimer's disease (AD). Prof. Itzhaki presented her work on the role of viruses, specifically HSV-1, in the pathogenesis of AD. She maintains that although it is true that most people harbor HSV-1 infection, either latent or active, nonetheless aspects of herpes infection can play a role in the pathogenesis of AD, based on extensive experimental evidence from AD brains and infected cell …

Chlamydia Pneumoniae: An Etiologic Agent For Late-Onset Dementia, Brian J. Balin Phd, Christine Hammond, Christopher S. Little, Susan Hingley, Zein Al-Atrache, Denah Appelt, Judith A Whittum-Hudson, Alan P Hudson

PCOM Scholarly Papers

The disease known as late-onset Alzheimer's disease is a neurodegenerative condition recognized as the single most common form of senile dementia. The condition is sporadic and has been attributed to neuronal damage and loss, both of which have been linked to the accumulation of protein deposits in the brain. Significant progress has been made over the past two decades regarding our overall understanding of the apparently pathogenic entities that arise in the affected brain, both for early-onset disease, which constitutes approximately 5% of all cases, as well as late-onset disease, which constitutes the remainder of cases. Observable neuropathology includes: neurofibrillary …
