Management Of Difficult Airway In A Pregnant Patient With Severely Reduced Mouth Opening, Faisal Shamim, Aly Bahadur, Dinaz Ghandhi, Anum Aijaz

Department of Anaesthesia

Pregnancy is associated with a wide variety of oral and dental changes ranging from gingivitis to odontogenic infections. If left untreated, severe dental abscess can progress to Ludwig's angina, which is a potentially lethal cellulitis that rapidly extends to the neck region and may lead to life-threatening upper airway obstruction. We report the case of a pregnant woman who presented with intense throbbing pain, trismus and severely reduced mouth opening due to dental abscess for the last one week. She required incision and drainage of abscess with extraction of third molar under general anaesthesia. There are some significant challenges to …

Currently, Alzheimer's disease (AD) accounts for more than half of all dementia cases. Although genetics, age, and environmental factors affect the disease, the cause of AD is not yet fully known. Various drugs have been proposed for the prevention and treatment of AD, but the delivery of these therapeutic agents to the brain is difficult. The blood–brain barrier prevents systemic drugs from accessing the central nervous system and designing a suitable system to overcome this barrier has attracted much attention. The intranasal pathway, given its proximity to the brain, provides a great opportunity for drug delivery. Understanding the physiological characteristics …

Dental Medicine Faculty Research

Introduction: Many studies in stem cell biology have demonstrated that dental pulp stem cells (DPSC) may be highly proliferative and capable of pluripotent differentiation into many different tissue types. Recent advances in stem cell research have outlined methods for directing in vitro or in vivo growth, viability, and proliferation, as well as differentiation of DPSC-although much remains to be discovered. Based upon this information, the primary objective of this study was to understand the functional biomaterials needed to more effectively direct DPSC viability, growth, and proliferation. Methods: Using an approved protocol, previously collected and isolated samples of DPSC from an …

Amelogenesis imperfecta is a congenital form of enamel hypoplasia. Although a number of genetic mutations have been reported in humans, the regulatory network of these genes remains mostly unclear. To identify signatures of biological pathways in amelogenesis imperfecta, we conducted bioinformatic analyses on genes associated with the condition in humans. Through an extensive search of the main biomedical databases, we found 56 genes in which mutations and/or association/linkage were reported in individuals with amelogenesis imperfecta. These candidate genes were further grouped by function, pathway, protein-protein interaction, and tissue-specific expression patterns using various bioinformatic tools. The bioinformatic analyses highlighted a group …

Oral Health Is Important, But How Important?, Alexander G. Dengel

Population Health Research Brief Series

Dental care is often overlooked as a priority and sometimes considered more of a chore rather than an important aspect of personal health. This oversight can lead to poor health outcomes like gingivitis, periodontitis, and even chronic illness like heart disease, diabetes, and cancer. This issue brief describes the short- and long-term effects of a poor dental health routine and the simple steps necessary to maintain a healthy smile.

Total Salivary Protein Concentration And Its Correlation To Dental Caries, Emyli Peralta, Jonathan Joseph

The Pegasus Review: UCF Undergraduate Research Journal

According to the World Health Organization, dental cavities are the number one chronic disease in children. Saliva coats the teeth all day and serves many functions to maintain and protect teeth. Saliva has many proteins that can be both detrimental and essential to the preservation of tooth enamel. The purpose of this study was to determine if a correlation exists between the total protein concentration in saliva and the prevalence of cavities in the mouth. We hypothesized that there would be a positive correlation between total salivary protein concentration and the prevalence of cavities in the participant.Saliva samples were collected …

The Potential Of Raman Spectroscopy In The Diagnosis Of Dysplastic And Malignant Oral Lesions, Ola Ibrahim, M. Toner, Steven Flint, Hugh Byrne, Fiona Lyng

Articles

Early diagnosis, treatment and/or surveillance of oral premalignant lesions are important in preventing progression to oral squamous cell carcinoma (OSCC). The current gold standard is through histopathological diagnosis, which is limited by inter and intra observer and sampling errors. The objective of this work was to use Raman spectroscopy to discriminate between benign, mild, moderate and severe dysplasia and OSCC in formalin fixed paraffin preserved (FFPP) tissues. The study included 72 different pathologies from which 17 were benign lesions, 20 mildly dysplastic, 20 moderately dysplastic, 10 severely dysplastic and 5 invasive OSCC. The glass substrate and paraffin wax background were …

Phenytoin Inhibits Cell Proliferation Through Microrna-196a-5p In Mouse Lip Mesenchymal Cells, Hiroki Yoshioka, Sai Shankar Ramakrishnan, Akiko Suzuki, Junichi Iwata

Faculty, Staff and Student Publications

Cleft lip (CL) is one of the most common birth defects. It is caused by either genetic mutations or environmental factors. Recent studies suggest that environmental factors influence the expression of noncoding RNAs [e.g., microRNA (miRNA)], which can regulate the expression of genes crucial for cellular functions. In this study, we examined which miRNAs are associated with CL. Among 10 candidate miRNAs (miR-98-3p, miR-101a-3p, miR-101b-3p, miR-141-3p, miR-144-3p, miR-181a-5p, miR-196a-5p, miR-196b-5p, miR-200a-3p, and miR-710) identified through our bioinformatic analysis of CL-associated genes, overexpression of miR-181a-5p, miR-196a-5p, miR-196b-5p, and miR-710 inhibited cell proliferation through suppression of genes associated with CL in cultured …
