They can be classified as functional or nonfunctional. If functional, the most common presentations are with hypertensive crisis or post-micturition syncope. A si lent pa raganglioma of th e bl adder ca n be easily m isdiagnosed w hich can resu lt in severe pe ri- oper ative morbidity. We pre sent a ca se of a male pati ent who was being m a naged fo r hype rt ension for 2-3 ye ars...

Perioral tissues are among the first areas to show signs of facial aging, leading many patients to seek perioral fillers as their initial cosmetic treatment. These fillers offer a temporary solution by enhancing volume and reducing common facial lines. Various regions within the perioral area can be targeted, including the lips, nasolabial folds, philtral columns, vertical lip rhytids, oral commissures, melomental folds, mentolabial folds, and nasolabial folds. The technique for injecting perioral fillers depends on the specific region, chosen product, and the desired outcome of augmentation...

AIM: To summarize the existing literature surrounding the influence of natural elements on course in hospital and to introduce clinicians to the concept of biophilic design and the potential for incorporation of nature into the hospital environment as a component of a therapeutic hospitalization. BACKGROUND: For decades, architects and designers have espoused the benefits of incorporating natural elements into the healthcare environment for therapeutic purposes...

Pre- and postoperative fixed orthodontic appliances are the customary and standard practice for patients with treatment planned for undergoing orthognathic surgery. Traditionally, most patients undergoing orthognathic surgeries are in their late teens. Although these patients still compose the greatest pool of the orthognathic surgery population, many patients seek orthognathic surgery later in life. This older patient population often has different concerns and goals than the younger patient population. One of these concerns is often the aesthetic appearance of fixed appliances and the time required to wear these appliances pre- and postoperatively...

OBJECTIVE: Segmental mandibular defects can occur due to various etiologies, including trauma and tumor resection. Reconstruction should provide adequate support for subsequent dental rehabilitation and allow for proper occlusion. Nonvascularized bone grafts have been used for reconstructing mandibular defects in cases where vascularized grafts were not feasible. The objective of this study was to assess the success rate of these grafts in reconstruction of segmental defects of various sizes in the mandible...

SIGNIFICANCE: Current treatment for stage III colorectal cancer (CRC) patients involves surgery that may not be sufficient in many cases, requiring additional adjuvant systemic therapy. Identification of this latter cohort that is likely to recur following surgery is key to better personalized therapy selection, but there is a lack of proper quantitative assessment tools for potential clinical adoption. AIM: The purpose of this study is to employ Mueller matrix (MM) polarized light microscopy in combination with supervised machine learning (ML) to quantitatively analyze the prognostic value of peri-tumoral collagen in CRC in relation to 5-year local recurrence (LR)...

OBJECTIVES: To systematically review the literature regarding previously described peritonsillar abscess (PTA) drainage simulation. DATA SOURCES: PubMed, Scopus, Web of Science, Ovid, and Cochrane. REVIEW METHODS: A search of the abovementioned databases was performed in August 2022 using the terms "peritonsillar abscess/quinsy," "incision/drainage/aspiration," and "simulation." No time restrictions were applied. We included studies that clearly described how their PTA models were built and underwent validation from experts and/or evaluation from trainees...

BACKGROUND: This was a retrospective cohort study of adult patients undergoing uncomplicated elective colectomy using the National Surgical Quality Improvement Program database from January 2012 to December 2019. A colectomy is deemed uncomplicated if there was no complication reported during the hospitalization. The objective of this study was to examine the association between discharge timing and post-discharge complications in patients who undergo uncomplicated elective colectomy...

BACKGROUND: Studies comparing conversion from laparoscopic to open approaches to colectomy have found an association between conversion and morbidity, mortality, and length of stay, suggesting that certain patients may benefit from an open approach "up-front." AIM: The objective of this study was to use machine learning algorithms to develop a model enabling the prediction of which patients are likely to require conversion. METHODS AND RESULTS: We used ACS NSQIP data to identify patients undergoing colectomy (2014-2019)...

BACKGROUND: The overdose crisis continues across Canada which calls for novel harm reduction strategies. Previous research indicates that a majority of eHealth solutions are cost-effective however current literature on the cost-benefit of eHealth for harm reduction is sparse. The National Overdose Response Service (NORS) is a Canada-wide telephone-based harm reduction service. Service users can call the phone number and connect to a peer who can virtually monitor the substance use session and dispatch appropriate interventions in the case of overdose...

OBJECTIVE: The purpose of this article is to review the current uses of virtual reality (VR) and augmented reality (AR) in oral and maxillofacial surgery. We discuss the use of VR/AR in educational training, surgical planning, advances in hardware and software, and the implementation of VR/AR in this field. STUDY DESIGN: A retrospective comprehensive review search of PubMed, Web of Science, Embase, and Cochrane Library was conducted. The search resulted in finding 313 English articles in the last 10 years...

The peri-tumoural stroma has been explored as a useful source of prognostic information in colorectal cancer. Using Mueller matrix (MM) polarized light microscopy for quantification of unstained histology slides, the current study assesses the prognostic potential of polarimetric characteristics of peri-tumoural collagenous stroma architecture in 38 human stage III colorectal cancer (CRC) patient samples. Specifically, Mueller matrix transformation and polar decomposition parameters were tested for association with 5-year patient local recurrence outcomes...

PURPOSE: Olfactory dysfunction (OD) is a common presenting sign of coronavirus-19 (COVID-19) infection and remains persistent in up to 7 % of patients one year after diagnosis. However, demographic, socioeconomic, and medical risk factors for persistent OD are not well understood. This study aims to determine risk factors for development and persistence of OD amongst patients with COVID-19 infection. MATERIALS AND METHODS: This prospective, observational questionnaire study was performed at a tertiary-level, academic center...

BACKGROUND: Currently, no guidelines exist regarding the appropriate time from diagnosis to treatment among pancreatic adenocarcinoma patients. Herein, we aim to define the median time to treatment in pancreatic adenocarcinoma, factors associated with treatment delay, and prognostic significance. METHODS: We conducted a retrospective study of pancreatic adenocarcinoma patients, stage I-IV, at a tertiary referral center (2017-2020). We subdivided time to treatment (days) into 4 components: (1) Ti : symptom onset to initial provider evaluation, (2) Tii : initial provider evaluation to diagnosis, (3) Tiii : diagnosis to specialist consultation, (4) Tiv : specialist visit to treatment...

The oxide-based systems often suffer from higher overpotentials compared to transition metal sulphides and phosphides for the electrochemical hydrogen evolution reaction. Interestingly, the generation of oxygen vacancy has been seen as strategy for further activating transition metal oxides (NiCo2O4 as a model system) for electrochemical watersplitting. Herein, we employ the temperature ramp strategy (ambient air calcination) for the generation of oxygen vacancies in NiCo2O4 (NCO) towards tuning of electrocatalytic enhancements...

AIM: The simple six-variable Codman score is a tool designed to reduce the complexity of contemporary risk-adjusted postoperative mortality rate predictions. We sought to externally validate the Codman score in colorectal surgery. METHODS: The American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) participant user file and colectomy targeted dataset of 2020 were merged. A Codman score (composed of six variables: age, American Society of Anesthesiologists score, emergency status, degree of sepsis, functional status and preoperative blood transfusion) was assigned to every patient...
