Improving the Medical Curriculum in Predoctoral Dental Education: Recommendations From the American Association of Oral and Maxillofacial Surgeons Committee on Predoctoral Education and Training.

Dental procedures are often performed on patients who present with some level of medical fragility. In many dental schools, the exercise of taking a medical history is all too often a transcription of information to the dental chart, with little emphasis on the presurgical risk assessment and the development of a treatment plan appropriate to the medical status of the dental patient. Changes in dentistry, driven by an increasingly medically complex population of dental patients, combined with treatment advances rooted in the biomedical sciences necessitate the adaptation of our dental education to include a stronger background in systemic health. Many predoctoral educators in the American Association of Oral and Maxillofacial Surgeons (AAOMS) have expressed concern about the medical preparedness of our dental students; therefore, the AAOMS and its Committee on Predoctoral Education and Training have provided recommendations for improving the medical curriculum in predoctoral dental education, including a strengthening of training in clinical medicine and biomedical sciences, with specific recommendations for improved training of our dental students and dental faculty.

Auto-Brewery Syndrome and General Anesthesia: A Case Report.

Auto-brewery syndrome (ABS) is a rare condition in which ethanol is endogenously fermented by fungi in the gut following a carbohydrate-rich meal, resulting in intoxication. We present a case of a patient with ABS successfully undergoing general anesthesia for symptomatic wisdom tooth extraction. During previous anesthetics, the patient had experienced postoperative nausea and vomiting (PONV) and awareness under anesthesia. Patients with ABS can be optimized for anesthesia by assessing hepatic function, avoiding perioperative oral carbohydrates, increasing anesthetic depth, multimodal PONV prophylaxis, and avoidance of broad-spectrum antibiotics.

Resident selection, assessment, and management: Proceedings of the 2022 ADEA Advanced Dental Education Summit.

The fifth biennial Advanced Dental Education Summit was organized by the ADEA Council on Advanced Education Programs. With a focus on "Resident selection, assessment, and management," the summit aimed to discuss best practices for selecting, assessing, and managing advanced education residents. Expert presentations covered the resident's journey from interview to graduation, emphasizing strategies for supporting resident wellness, success, and evaluation. The summit provided recommendations, including the incorporation of psychosocial assessments in the selection process, early recognition of behavioral issues, clearly defining clinical competencies, and creating a culture of wellness through supportive policies and structures.

Global doctor opinion versus a patient questionnaire for the outcome assessment of treated temporomandibular disorder patients.

PURPOSE: Accurately assessing treatment outcomes has become increasingly important for maintaining hospital privileges. When these assessments are based on the judgment of the treating doctor, there is often an inherent positive bias. As a result, there has been increased interest in using patient-based assessments. The purpose of this study was to compare doctor's and patient's assessments of the outcomes of treatment in a series of patients with various temporomandibular disorders (TMDs). MATERIALS AND METHODS: Fifty-two consecutive TMD patients were initially given a questionnaire designed to evaluate their pain, problems eating and sleeping, the occurrence of headache and earache, the presence of temporomandibular joint pain and/or jaw stiffness in the morning, and interference with daily activity. The patients then filled out the same questionnaire at each post-treatment visit, and the findings were compared with the baseline information. At each visit, the treating doctor also recorded a global evaluation of the patient's progress as excellent, good, fair, or poor. RESULTS: Comparison of the doctor's global evaluation with the patient's evaluation based on the questionnaire showed a discrepancy in 44% of the cases. When there was a discrepancy, the doctor scored the improvement better than the patient 54.5% of the time and worse than the patient 45.5% of the time. CONCLUSIONS: The results of this study confirm the unreliability of using a global opinion by the treating doctor for outcome assessment in patients with various TMDs.

Cardiac Arrest Upon Induction of General Anesthesia.

There are numerous causes of cardiac arrest in the perioperative period, including hypoxia, hypovolemia, and vagal response to medications or procedures during routine anesthetics. Initiation of adequate cardiopulmonary resuscitation, administration of epinephrine, and application of a defibrillator, with shocking when applicable, are all essential steps in achieving return of spontaneous circulation. Knowledge and utilization of monitoring equipment can alert the provider to problems leading to cardiac arrest as well as ensure proper resuscitative efforts during the event. Polypharmacy is quite common with many of today's special needs patients. It is important to understand the medications they are taking as well as the potential interactions that may occur with drugs given during sedation and general anesthesia. The following is a case report of cardiac arrest including asystole and pulseless electrical activity in a 27-year-old man with autism and behavioral problems who presented for restorative dentistry under general anesthesia in the ambulatory surgery setting.

Development and Implementation of a Uniform Dental School-Wide Electronic Treatment Consenting Process for Patients.

One approach to enhancing quality care outcomes and patient safety is through effective implementation of clinical risk reduction strategies. Clinical risk identification at The Ohio State University College of Dentistry revealed lack of a standardized informed consenting process for patients. The purpose of this project was to develop and implement a uniform college-wide informed consenting process. An operating procedure was also developed. The resulting consenting documents used a uniform approach in which clinics could use a basic readable and processable informed consent template. The template was edited for appropriate content suitable for an electronic health record. Implementing an operating procedure along with associated contemporary uniform electronic informed consent forms was realized through efforts of a core team with informed consenting experience. The core team developed the template and the majority of all documents before editing all division-based consents. This method relied on growing expertise and momentum. Outcomes of chart audits following implementation of the new electronic informed consent forms showed a transitory increase in missing consent forms. Subsequently, the number of missing consent forms decreased to near pre-implementation levels. Patient refunds related to missing informed consent issues dropped, and patient satisfaction remained high throughout the project. Other institutions can use this project as a guide for developing their own uniform consent forms and process.

Oral precancerous and malignant lesions associated with graft-versus-host disease: report of 2 cases.

The development of secondary malignancies has been recognized as a potential iatrogenic complication in patients who have graft-versus-host disease secondary to bone marrow transplantation. Lymphohematopoietic cancer is most frequent, although solid malignancies have also been reported. We describe 2 patients with graft-versus-host disease who developed oral precancerous and malignant lesions. The first patient, a 24-year-old white man, had erythroplakia of the buccal mucosa that proved to be carcinoma in situ histopathologically. The second patient, a 14-year-old Hispanic boy, developed synchronous cutaneous and lingual squamous cell carcinomas. The current cases and similar sporadic case reports found in the literature highlight the susceptibility of patients with graft-versus-host disease to the development of oral cancer. Therefore, it is recommended that thorough evaluation of the oral mucosa and close follow-up be offered to all patients treated with bone marrow transplantation and particularly to those who develop graft-versus-host disease.

Topical application of a mucoadhesive freeze-dried black raspberry gel induces clinical and histologic regression and reduces loss of heterozygosity events in premalignant oral intraepithelial lesions: results from a multicentered, placebo-controlled clinical trial.

PURPOSE: Approximately 30% higher grade premalignant oral intraepithelial neoplasia (OIN) lesions will progress to oral cancer. Although surgery is the OIN treatment mainstay, many OIN lesions recur, which is highly problematic for both surgeons and patients. This clinical trial assessed the chemopreventive efficacy of a natural product-based bioadhesive gel on OIN lesions. EXPERIMENTAL DESIGN: This placebo-controlled multicenter study investigated the effects of topical application of bioadhesive gels that contained either 10% w/w freeze-dried black raspberries (BRB) or an identical formulation devoid of BRB placebo to biopsy-confirmed OIN lesions (0.5 g × q.i.d., 12 weeks). Baseline evaluative parameters (size, histologic grade, LOH events) were comparable in the randomly assigned BRB (n = 22) and placebo (n = 18) gel cohorts. Evaluative parameters were: histologic grade, clinical size, and LOH. RESULTS: Topical application of the BRB gel to OIN lesions resulted in statistically significant reductions in lesional sizes, histologic grades, and LOH events. In contrast, placebo gel lesions demonstrated a significant increase in lesional size and no significant effects on histologic grade or LOH events. Collectively, these data strongly support BRB's chemopreventive impact. A cohort of very BRB-responsive patients, as demonstrated by high therapeutic efficacy, was identified. Corresponding protein profiling studies, which demonstrated higher pretreatment levels of BRB metabolic and keratinocyte differentiation enzymes in BRB-responsive lesions, reinforce the importance of local metabolism and differentiation competency. CONCLUSIONS: Results from this trial substantiate the LOH reductions identified in the pilot BRB gel study and extend therapeutic effects to significant improvements in histologic grade and lesional size.

Implications for oxidative and nitrative stress in the pathogenesis of AIDS-related Kaposi's sarcoma.

AIDS-related Kaposi's sarcoma (AIDS-KS), which is the most prevalent AIDS related cancer, arises in a unique environment characterized by profound immunosuppression in conjunction with sustained immunostimulation. Persistent inflammation and the accompanying increased production of reactive species can promote carcinogenesis by numerous routes including sustained cell proliferation, initiation of nuclear and mitochondrial DNA mutations and induction of a proangiogenic environment. Furthermore, during conditions of continuous inflammation, protein nitration can result in irreversible inactivation of enzymes including the cytoprotective and reactive species degrading enzyme, mitochondrial superoxide dismutase (MnSOD). Because MnSOD serves as a putative tumor suppressor gene in addition to its reactive species inactivating capacities, the loss of MnSOD's cytoprotective functions could markedly facilitate malignant transformation. The purpose of this study was to investigate biochemical and molecular pathways by which reactive species facilitate AIDS-KS pathogenesis. Immunohistochemical studies of AIDS-KS tumors showed intense AIDS-KS lesional cell staining for MnSOD, inducible nitric oxide synthase (NOS 2) and the presence of a cellular 'fingerprint' of nitrative stress, 3-nitrotyrosine. Collectively, these results that imply reactive species stress occurs in situ. Similarly, cultured AIDS-KS cells derived from the AIDS-KS tumors contained both MnSOD protein and the 'high output' isoform, NOS 2. Co-localization studies established that the mitochondria are a primary site for 3-nitrotyrosine localization and immunoprecipitation/immunoblotting experiments confirmed that MnSOD tyrosine nitration occurs in AIDS-KS cells. Functional SOD assays showed that AIDS-KS cells possess significantly lower MnSOD activity relative to matched control cells; findings which correspond with ongoing MnSOD tyrosine nitration and subsequent inactivation within AIDS-KS cells. These results, which show in situ evidence of reactive species stress within AIDS-KS tumors and functional deficits attributable to nitrative stress in tumor-derived AIDS-KS lesional cells, imply that reactive species are intimately associated with AIDS-KS pathogenesis and provide insights for development of novel strategies for AIDS-KS clinical treatments.

AIDS-related Kaposi's sarcoma cells rapidly internalize endostatin, which co-localizes to tropomysin microfilaments and inhibits cytokine-mediated migration and invasion.

AIDS-related Kaposi's sarcoma (KS) is the most common HIV-related malignancy. In some respects, KS is analogous to other angioproliferative diseases, in that KS lesions are highly vascularized and promoted by inflammatory cytokines. However, unlike other cancers or inflammatory mediated vascular diseases, KS is unique in that the KS lesional cells both express and respond to the complete angiogenic cytokines vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF). Therefore, the angiogenic phenotype, which is crucial for cancer progression, is inherent to KS tumor cells. Due to the recognized importance of angiogenesis in cancer progression, numerous angiostatic agents are being investigated as potential therapeutic agents. One such agent is endostatin, which is a 20-kDa carboxyl-terminal fragment of collagen XVIII that has demonstrated potent angiostatic activities at both the in vivo and in vitro levels. Since endostatin is recognized as a potent angiostatic agent, the majority of in vitro endostatin studies have evaluated its effects on endothelial cells. Although KS cells are speculated to arise from endothelial cell precursors and KS lesions are highly vascularized, no previous studies have investigated endostatin-KS cell interactions. This present study evaluated endostatin's effects on KS tumor cell: (i) signal transduction (endostatin internalization and transcription factor activation), and (ii) migration and invasion (functional activity assays and tropomysin co-localization). Our results show that KS cells rapidly internalize endostatin and that endostatin initiates activation of the transcription activating factors nuclear factor-kappaB (NF-kappaB) and activating protein 1 (AP-1). Our data also show that internalized endostatin co-localizes to tropomysin microfilaments and acts to inhibit KS cell migration and invasion in response to the clinically relevant angiogenic cytokines VEGF and bFGF. As a consequence of its combined angiostatic and antitumorigenic activities, endostatin could provide dual therapeutic benefits for patients with mucocutaneous KS.
