Factors Associated With Nutritional Status in Patients With Removable Dentures: A Cross-Sectional Study.

Background Tooth loss can impair masticatory function and may subsequently result in malnutrition. This study aimed to investigate the factors associated with controlling nutritional status (CONUT) scores, which assess malnutrition risk, in patients with removable dentures. Materials and methods In this cross-sectional study, data were obtained from a consecutive sampling of 192 patients (mean age 72.

Effectiveness of art-based health education on anemia and health literacy among pregnant women in Western Nepal: A randomized controlled trial.

Objective: As Nepalese pregnant women vary widely in literacy levels and cultural backgrounds and are reluctant to make decisions about their health, general interventions are insufficient to improve maternal anemia. This study aimed to assess the effectiveness of "face-to-face health education using educational material created using pictures, photos, and nomograms" in reducing anemia and improving health literacy.

Methods: A total of 156 Nepalese pregnant women with hemoglobin (Hb) levels below 11.

Preliminary outcomes of boron neutron capture therapy for head and neck cancers as a treatment covered by public health insurance system in Japan: Real-world experiences over a 2-year period.

Purpose: Since June 2020, boron neutron capture therapy (BNCT) has been a health care service covered by health insurance in Japan to treat locally advanced or recurrent unresectable head and neck cancers. Therefore, we aimed to assess the clinical outcomes of BNCT as a health insurance treatment and explore its role among the standard treatment modalities for head and neck cancers.

Materials And Methods: We retrospectively analyzed data from patients who were treated using BNCT at Kansai BNCT Medical Center, Osaka Medical and Pharmaceutical University, between June 2020 and May 2022.

High-Q two-dimensional photonic crystal nanocavity on glass with an upper glass thin film.

We numerically analyze two-dimensional photonic crystal (PhC) nanocavities on glass with a thin glass film on top of the structure. We investigated a multistep heterostructure GaAs PhC nanocavity located on glass. We found that covering the structure even with a very thin glass film efficiently suppresses unwanted polarization mode conversion occurring due to the asymmetric refractive index environment around the PhC.

Prognostic value of electroneurography using the midline method for predicting the development of synkinesis after peripheral facial palsy.

Objective: The prognostic value of electroneurography (ENoG) for predicting the incidence of synkinesis is reportedly about 40 % using the formal standard method (ENoG-SM). However, the prognostic value of ENoG using the newly developed midline method (ENoG-MM) has not been determined. The aim of this study was to demonstrate the optimal prognostic value and advantages of ENoG-MM for predicting the incidence of synkinesis.

Differential expression of TRKB tyrosine kinase in the two histological types of parotid salivary duct carcinoma with cancer aggressiveness.

Parotid salivary duct carcinoma (SDC) is a rare and aggressive parotid gland carcinoma (PGC). SDC has two origins: de novo and ex pleomorphic adenoma (SDC ex PA); however, because of its rarity, the clinical and molecular features of the two types of SDC are not sufficiently understood. Here, we studied the differences in their clinicopathological and molecular features using clinical specimens while comparing them to those of adenoid cystic carcinoma (AdCC), an intermediate-grade PGC.

Central node dissection from the perspective of lateral neck node metastasis in papillary thyroid carcinoma.

Objectives: Controversy exists on how to handle central lymph nodes in papillary thyroid carcinoma, particularly regarding indications for prophylactic central neck dissection (CND). Central node metastases are more difficult to diagnose preoperatively than lateral node metastases.

Methods: We enrolled 493 patients with papillary thyroid carcinoma treated at our department in the past 22 years.

Utility of palliative prognostic index and neutrophil-to-lymphocyte ratio in predicting prognosis of end-stage squamous cell carcinoma of head and neck.

Background: The purpose of this study was to examine the factors influencing the prognosis of end-stage head and neck squamous cell carcinoma (HNSCC) and to develop a more useful prognostic index.

Patients And Methods: This retrospective observational study included 79 patients with end-stage HNSCC. Patients were grouped by patient factors and prognostic indicators, and overall survival from the start of Best Supportive Care was compared for each group.

Clinicopathological characteristics of four major histological types of high-grade parotid carcinoma.

Objective: High-grade parotid carcinoma generally has a poor prognosis, and the histological type is mucoepidermoid carcinoma (MEC), salivary duct carcinoma (SDC), carcinoma ex pleomorphic adenoma (CEPA), or adenoid cystic carcinoma (AdCC) in the majority of cases.

Methods: During the 23-year period from September 1999 to December 2022, 250 patients with parotid carcinoma underwent initial treatment and had the histopathological type of their carcinoma. Retrospective study evaluated 111 MEC, SDC, CEPA, or AdCC cases among 134 patients with high-grade parotid carcinoma.

Evaluation of Vestibular Functions in a Case of Vestibular Migraine With Successful Treatment With Erenumab.

This is the first report of vestibular examinations before and after the successful treatment of vestibular migraine (VM), a common cause of recurrent vertigo, with calcitonin gene-related peptide (CGRP) receptor inhibitor. We evaluated a 42-year-old female with VM and concomitant probable Meniere's disease, whose headache and dizziness have improved promptly with the administration of erenumab, a CGRP receptor inhibitor. The sensorineural hearing loss in pure-tone audiometry, dysfunctions shown in vestibular examinations (cervical and ocular vestibular evoked myogenic potentials), and mild endolymphatic hydrops shown in gadolinium-enhanced inner ear magnetic resonance imaging, all in the right ear, revealed no change compared with those observed before treatment.

Tracheostomy in otorhinolaryngology education and training programs: A Japanese nationwide survey.

Objective: Surgical airway management is one of the most effective techniques for safe airway management. Within the training programs relating to knowledge and skills required by otorhinolaryngologists, tracheostomy and postoperative management are important items that must be fully understood by airway surgeons. We performed a nationwide survey to identify problems within tracheostomy and postoperative management in Japan in order to establish practical and safe guidelines for surgical airway management.

Facial nerve dissection in parotid surgery: a microscopic investigation study.

In parotid surgery, it is crucial to identify and preserve the facial nerve, which runs through the parotid gland. The purpose of this study was to histologically clarify two clinical questions: whether "superficial" and "deep" lobes exist anatomically and what are the structures surrounding facial nerve. Parotid gland tissues were obtained from dissection of donated cadavers.

Tumor localization is the important factor for recovery time of postoperative facial nerve paralysis in benign parotid surgery.

Objective: Facial nerve paralysis is the most problematic complication of surgery for parotid tumors. This study aimed to examine the progress of recovery from postoperative transient facial nerve paralysis (POFNP).

Methods: Participants were 203 patients who developed POFNP after benign parotid surgery.

The Landscape of MYB/MYBL1- and Peri-MYB/MYBL1-Associated Rearrangements in Adenoid Cystic Carcinoma.

Approximately 60% of adenoid cystic carcinoma (AdCC) cases are positive for MYB::NFIB or MYBL1::NFIB, whereas MYB/MYBL1 oncoprotein, a key driver of AdCC, is overexpressed in most cases. Juxtaposition of superenhancer regions in NFIB and other genes into the MYB/MYBL1 locus is an attractive oncogenic hypothesis for AdCC cases, either negative or positive for MYB/MYBL1::NFIB. However, evidence supporting this hypothesis is insufficient.

Management and outcome of adenoid cystic carcinoma of the major salivary glands: the 22-year experience of a single institution.

Background: Prognostic factors and survival rate are difficult to determine for adenoid cystic carcinoma(AdCC) of salivary glands.

Aims/objectives: To clarify the clinical characteristics of AdCC and examine factors associated with recurrence and prognosis by histopathological grade classification.

Materials And Methods: Twenty-five patients with AdCC of the parotid gland and 10 patients with AdCC of the submandibular gland were included.

Increased Chymase-Positive Mast Cells in High-Grade Mucoepidermoid Carcinoma of the Parotid Gland.

It has long been known that high-grade mucoepidermoid carcinoma (MEC) has a poor prognosis, but the detailed molecular and biological mechanisms underlying this are not fully understood. In the present study, the pattern of chymase-positive mast cells, as well as chymase gene expression, in high-grade MEC was compared to that of low-grade and intermediate-grade MEC by using 44 resected tumor samples of MEC of the parotid gland. Chymase expression, as well as chymase-positive mast cells, was found to be markedly increased in high-grade MEC.

Saccular functions differ for Meniere's disease with and without coexisting headaches.

Objectives: To elucidate the differences between the cases of Meniere's disease (MD) with and without coexisting headaches, especially migraine. The clinical characteristics and vestibular functions are compared.

Subjects: Fifteen patients with definite unilateral MD without headaches (MD/H-; 10 males and 5 females; mean age of 55.

Predicting postoperative facial nerve paralysis by using intraoperative nerve monitoring during parotid surgery.

Objectives: To investigate a method for predicting postoperative facial nerve paralysis (POFNP) during parotid surgery using intraoperative nerve monitoring (IONM).

Methods: We assessed prediction for POFNP by using IONM, comparing between stimulation in the facial nerve trunk and each branch by using facial nerve monitoring. The amplitude response ratio (ARR) was calculated for the trunk/periphery.
