Non-Recurrent Laryngeal Nerve: A Case Report And Review Of Literature, Muhammad Hassan Danish, Rahim Dhanani, Huzaifa Moiz, Mubasher Ikram

Section of Otolaryngology, Head & Neck Surgery

Right recurrent laryngeal nerve can take a "Non-Recurrent" course and can present as a Non Recurrent Laryngeal nerve which is a rare entity. Such anomalies can lead to difficulty in locating the laryngeal nerve during thyroid surgeries and there are higher chances of it being injured. Therefore, surgeons should be mindful of this entity. We report the case of a 53-year-old lady who underwent thyroid surgery and a right Non Recurrent Laryngeal Nerve was identified intra-operatively.

The palatomaxillary structure plays critical roles in both form and function of the midface. Surgical defects of the palate and maxilla can be associated with significant morbidity and deformity. Various defect classification systems have been used to assist in reconstruction and rehabilitation. Reconstructive options include prosthetic rehabilitation, local flaps, and free tissue transfer. Here, we review the functional and surgical anatomy of the palatomaxillary complex, defect classification systems, and provide an overview of reconstructive options.

Effects Of Alternative Chemotherapeutic Agents On Thyroid Cancer Cell Line Ml-1, Husref Rizvanovic

Graduate Theses/Dissertations

Though differentiated thyroid carcinomas have decent prognosis when detected early, radioactive iodine (RAI) resistant and advanced thyroid cancers are still difficult to treat with existing therapies. Better therapeutic agents are needed. Studies have shown that aggressive thyroid cancers (ML-1) express the extracellular matrix protein, matrix metalloproteinase (MMP-2). MMP-2 has been linked to metastasis and aggressiveness of several cancers and has been shown to play a crucial role in tumor invasion. Chlorotoxin is a selective MMP-2 receptor agonist, and Saporin is a well-known ribosome-inactivating protein used for anti-cancer treatment; however, these two agents have never been studied when conjugated together. I …

Genetic research has revealed pro-opiomelanocortin (POMC) to be a fundamental regulator of energy balance and body weight in mammals. Within the brain, POMC is primarily expressed in the arcuate nucleus of the hypothalamus (ARC), while a smaller population exists in the brainstem nucleus of the solitary tract (POMCNTS). We performed a neurochemical characterization of this understudied population of POMC cells using transgenic mice expressing green fluorescent protein (eGFP) under the control of a POMC promoter/enhancer (PomceGFP). Expression of endogenous Pomc mRNA in the nucleus of the solitary tract (NTS) PomceGFP cells was confirmed using fluorescence-activating cell sorting (FACS) followed by …

Management Of Laryngotracheal Trauma: A Review Of Current Trends And Future Directions, Muhammad Wasif, Rahim Dhanani, Shayan Khalid, Mohammad Sohail Awan, Muhammad Hassan Danish, Huzaifa Moiz, Hamdan Ahmed Pasha

Section of Otolaryngology, Head & Neck Surgery

Laryngotracheal trauma is rare but can pose serious threats to one's life. Presenting symptoms vary according to the severity of injury. Immediate Airway control is first step in the management, intubation should be considered by a senior member of the trauma team if the injury is minor while tracheostomy should be reserved for more severe injuries. Evaluation by a fibre-optic laryngoscopy and CT scan should be done whenever possible. Reconstruction is done according to the site involved using suture, titanium miniplates and stents. Tissue engineering has added a new horizon in this management but up till now complete laryngotracheal regeneration …

Assessing Lymphatic Route Of Csf Outflow And Peripheral Lymphatic Contractile Activity During Head-Down Tilt Using Near-Infrared Fluorescence Imaging, John C Rasmussen, Sunkuk Kwon, Amanda Pinal, Alexander Bareis, Fred C Velasquez, Christopher F Janssen, John R Morrow, Caroline E Fife, Ron J Karni, Eva M Sevick-Muraca

Faculty, Staff and Student Publications

Evidence overwhelmingly suggests that the lymphatics play a critical role in the clearance of cerebrospinal fluid (CSF) from the cranial space. Impairment of CSF outflow into the lymphatics is associated with a number of pathological conditions including spaceflight-associated neuro-ocular syndrome (SANS), a problem that limits long-duration spaceflight. We used near-infrared fluorescence lymphatic imaging (NIRFLI) to dynamically visualize the deep lymphatic drainage pathways shared by CSF outflow and disrupted during head-down tilt (HDT), a method used to mimic the cephalad fluid shift that occurs in microgravity. After validating CSF clearance into the lymph nodes of the neck in swine, a pilot …

This study offers a novel description of the sinonasal microbiome, through an unsupervised machine learning approach combining dimensionality reduction and clustering. We apply our method to the International Sinonasal Microbiome Study (ISMS) dataset of 410 sinus swab samples. We propose three main sinonasal “microbiotypes” or “states”: the first is Corynebacterium-dominated, the second is Staphylococcus-dominated, and the third dominated by the other core genera of the sinonasal microbiome (Streptococcus, Haemophilus, Moraxella, and Pseudomonas). The prevalence of the three microbiotypes studied did not differ between healthy and diseased sinuses, but differences in their distribution were evident based …

Prevention Of Oral Mucositis In Cancer Patients, Patricia E. Biel

Evidence-Based Practice Project Reports

Oral mucositis [OM] is one of the most severe non-hematological problems related to cancer treatments and can impact quality of life. It is linked to poorer outcomes due to the associated weight loss, pain, dehydration, and risk of developing life-threatening infections. The purpose of this evidence-based practice project was to determine if OM is preventable with the use of an oral care protocol and zinc supplementation when compared to use of oral care protocols alone. The Johns Hopkins Nursing Evidence-Based Practice Model was used to guide project implementation in an outpatient oncology office. Recommendations were developed from an exhaustive review …

Department of Surgery Docs

Introduction: Oral squamous cell carcinoma (OSCC) the sixth leading cancer worldwide ranks as the most common cancer in males, and the third most common in females in Pakistan. It is influenced by risk factors which are widely consumed in our population. The epidermal growth factor receptor (EGFR) is a tyrosine kinase receptor that is imperative for cell signalling, growth and differentiation. It is mutated and overexpressed in a variety of cancers, while in OSCC it has been linked to poor patient survival; premalignant to malignant transformation and recurrence. This study investigates the use of EGFR as a prognostic factor …
