Background: Flow-through flaps (FTFs) are an advanced technique in which a free flap is anastomosed to the pedicle of another free flap to reconstruct extensive head and neck defects when recipient vessels are scarce.

Methods: A multi-institutional cohort of FTFs used for head and neck reconstruction were reviewed. For comparison, FTF outcomes were compared to free flaps that required vein grafts (VG) to reach distant recipient vessels.

Introduction: Temporomandibular disorder (TMD) is a common, yet potentially debilitating syndrome that negatively impacts patient quality of life. In patients with severe variants of TMD, temporomandibular joint (TMJ) devices have been utilized to replace the joint altogether. However, the risk profile and consequent cost-benefit ratio of these devices is largely debated.

Article Synopsis
  • * A study compared blood samples from 10 healthy individuals and 10 anemic patients with oral diseases, revealing that anemic patients showed lower hemoglobin and red blood cell counts alongside significant changes in other hematological parameters associated with iron deficiency anemia (IDA).
  • * Findings suggest that patients with oral diseases experience more pronounced symptoms of IDA, indicating a significant prevalence of iron deficiency compared to healthy individuals, underscoring the importance of monitoring hematological health in these patients.

Purpose: While several clinical practice guidelines (CPGs) exist to guide clinical decision-making in patients with generalized cancer pain, to date there has been no comprehensive review of their quality. Our aim was to address this deficiency via the Appraisal of Guidelines for Research and Evaluation (AGREE II) tool.

Design: Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline-based systematic literature search followed by AGREE II appraisal of identified CPGs.

Introduction In children with acute illness or injury, timely access to healthcare is crucial for optimal outcomes, including early identification, prompt stabilization, and appropriate referral. Prehospital transport practices often represent a weak link in the system and are frequently underreported. Enhancing these practices could greatly benefit pediatric care.

Objective: To investigate primary site surgical resection and overall survival (OS) in clinically distantly metastatic (cM1) oral cavity squamous cell carcinoma (OCSCC).

Methods: The 2006-2018 National Cancer Database was queried for patients presenting with cM1 OCSCC who underwent chemotherapy. Binary logistic, Kaplan-Meier, and multivariable Cox proportional hazards regression models were implemented.

Objective: Mandibular plate reconstruction (MPR) is often indicated after tumor ablation, osteoradionecrosis excision, and traumatic bone loss to restore oral functionality and facial cosmetics. There are limited analyses identifying risk factors that lead to plate infection (PIn), exposure, and removal ("plate complications").

Study Design: Retrospective cohort study.

The potential of Raman hyperspectral imaging with a 785 nm excitation line laser was examined for the detection of aflatoxin contamination in corn kernels. Nine-hundred kernels were artificially inoculated in the laboratory, with 300 kernels each inoculated with AF13 (aflatoxigenic) fungus, AF36 (nonaflatoxigenic) fungus, and sterile distilled water (control). One-hundred kernels from each treatment were subsequently incubated for 3, 5, and 8 days.

Objective: To describe the use of transoral robotic surgery (TORS) in conjunction with intraoperative localization techniques for removal of challenging upper aerodigestive tract (UADT) foreign bodies.

Methods: Three cases were taken to the operating room for removal of UADT foreign bodies. Two of these cases had previously undergone failed surgery(s).

Article Synopsis
  • * In a study of 84 patients, 22.6% were diagnosed with CRS post-surgery, and 58.3% showed signs of sinus inflammation for over six months, indicating a significant issue with sinus health after surgery.
  • * Factors like chemotherapy and prior sinus medication usage were linked to a greater need for sinus treatment, suggesting that further attention to sinus issues post-surgery could improve long-term quality of life for these patients.

Importance: Circulating tumor human papillomavirus DNA (ctHPV DNA) has shown potential as a biomarker capable of improving outcomes in patients with HPV-related oropharyngeal (OP) cancer. It can be isolated from plasma or saliva, with the latter offering reduced invasiveness and theoretic reduction of lead time.

Objective: To perform a systematic review and meta-analysis on the accuracy of salivary ctHPV DNA for detecting HPV-associated OP cancer.

With cancer immunotherapy and precision medicine dynamically evolving, there is greater need for pre-clinical models that can better replicate the intact tumor and its complex tumor microenvironment (TME). Precision-cut tumor slices (PCTS) have recently emerged as an ex vivo human tumor model, offering the opportunity to study individual patient responses to targeted therapies, including immunotherapies. However, little is known about the physiologic status of PCTS and how culture conditions alter gene expression.

Maize (Zea mays), a major food crop worldwide, is susceptible to infection by the saprophytic fungus Aspergillus flavus that can produce the carcinogenic metabolite aflatoxin (AF) especially under climate change induced abiotic stressors that favor mold growth. Several studies have used "-omics" approaches to identify genetic elements with potential roles in AF resistance, but there is a lack of research identifying the involvement of small RNAs such as microRNAs (miRNAs) in maize-A. flavus interaction.
