Randomized Controlled Trial Comparative StudyComparison of Direct Laryngoscopy and Video Laryngoscopy in Intubating a Mannequin: Should Video Laryngoscopy Be Available to Manage Airway Emergencies in the Oral and Maxillofacial Surgery Office?
Video laryngoscopy (VL) is an innovation in tracheal intubation that could be beneficial in an emergency situation. However, the technique could be detrimental if it prolongs intubation performed by an inexperienced physician. The purpose of this study was to compare direct laryngoscopy (DL) with VL skill for oral and maxillofacial surgery (OMS) residents and practitioners to assess the practicality of recommending the inclusion of VL as a component of OMS emergency airway management. ⋯ The combined findings with OMS residents and practitioners showed comparable total intubating times between DL and VL, which is consistent with what has previously been reported with other medical colleagues.

Comparative StudyEffects of Volatile Anesthetics on Oral Tissue Blood Flow in Rabbits: A Comparison Among Isoflurane, Sevoflurane, and Desflurane.
The aim of this study was to compare the concentration-dependent effects of isoflurane, sevoflurane, and desflurane on oral tissue blood flow. ⋯ The results of this study suggest that each volatile anesthetic produced unique effects on blood flow in oral tissues and circulatory parameters. Among the 3 volatile anesthetics, desflurane produced the smallest effects on oral tissue blood flow.

Co-Graft of Bone Marrow Stromal Cells and Schwann Cells Into Acellular Nerve Scaffold for Sciatic Nerve Regeneration in Rats.
The conventional strategy for bridging large nerve defects, namely nerve autograft transplantation, results in donor-site morbidity. This detrimental consequence currently drives the search for alternatives. The authors used an acellular nerve scaffold filled with bone marrow stromal cells (BMSCs) and Schwann cells (SCs) to enhance regeneration. ⋯ This study is a step forward in the search for an alternative to the nerve autograft because it showed that co-grafting of BMSCs and SCs into an acellular nerve scaffold enhanced sciatic nerve functional recovery in rats. Its beneficial effect on sciatic injury regeneration was similar to the autograft group, although it did not exceed it.

Comparative StudyCan 3'-Deoxy-3'-((18)F) Fluorothymidine Out Perform 2-Deoxy-2-((18)F) Fluoro-D-Glucose Positron Emission Tomography/Computed Tomography in the Diagnosis of Cervical Lymphadenopathy in Patients With Oral/Head and Neck Cancer?
The present study investigated the performance of cellular metabolism imaging with 2-deoxy-2-((18)F) fluoro-D-glucose (FDG) versus cellular proliferation imaging with 3'-deoxy-3'-((18)F) fluorothymidine (FLT) in the detection of cervical lymph node metastases in oral/head and neck cancer. ⋯ FLT showed better overall performance for detecting lymphadenopathy on qualitative assessment within the total nodal population. This notwithstanding, FDG SUV performed better for pathologic discrimination within the visible lymph nodes.

Comparative Study Clinical TrialPostdischarge Nausea and Vomiting Remains Frequent After Le Fort I Osteotomy Despite Implementation of a Multimodal Antiemetic Protocol Effective in Reducing Postoperative Nausea and Vomiting.
To assess the prevalence of postdischarge nausea and vomiting (PDNV) after Le Fort I osteotomy with and without the use of a multimodal antiemetic protocol shown to decrease postoperative nausea and vomiting (PONV). ⋯ Modalities that successfully address PONV after Le Fort I osteotomy might fail to affect PDNV, which is prevalent in this population. Future investigation will focus on methods to minimize PDNV.
