A retrospective analysis of syphilis cases with a focus on otolaryngology at a university hospital.

Objectives: In recent years, there has been a notable increase in syphilis cases in Japan and Western countries. Syphilis, a classic sexually transmitted disease caused by treponemas, presents diagnostic challenges due to its diverse clinical manifestations. This study explores the diagnosis of syphilis in patients treated at our hospital.

Combined Positive Score and Cisplatin Sensitivity Are Prognostic Factors for Response to Nivolumab Therapy for Recurrent Metastatic Squamous Cell Carcinoma of the Head and Neck.

Background: Recurrent or metastatic squamous cell carcinoma of the head and neck (R/MHNSCC) is a challenging malignancy with a poor prognosis and limited treatment options. Nivolumab, an immune checkpoint inhibitor (ICI) targeting the programmed cell death/programmed cell death ligand 1 (PD-1/PD-L1) pathway, has emerged as a promising therapy for these patients. However, identifying biomarkers predictive of response to nivolumab remains critical for optimizing treatment strategies.

Swallowing Function and Quality of Life in Patients Treated With Transoral Videolaryngoscopic Surgery for Pharyngolaryngeal Cancer.

Background: It is controversial whether transoral resection for early pharyngolaryngeal cancer preserves swallowing function and quality of life. We investigated swallowing function and quality of life before and after transoral videolaryngoscopic surgery (TOVS).

Methods: Seventy-three patients with pharyngolaryngeal cancer who underwent TOVS between July 2012 and July 2022 were enrolled in this prospective analysis.

Safety and outcome of three-dimensional transoral videolaryngoscopic surgery.

Background: Transoral videolaryngoscopic surgery (TOVS) is widely used in Japan, and conventional two-dimensional (2D) endoscopic methods have been established. Three-dimensional (3D) endoscopic surgery offers superior distance perception because it provides stereoscopic views. Recently, we have developed 3D endoscopy for TOVS (3D TOVS).

Metachronous immune-related adverse events involving type 1 diabetes and isolated adrenocorticotropic hormone deficiency associated with pembrolizumab monotherapy for metastatic head and neck cancer: a case report.

Background: Immune checkpoint inhibitors might cause immune-related adverse events that are still largely unknown.

Case Presentation: An 80-year-old Asian female was diagnosed with cervical lymph node metastasis from lip cancer (cT1N0M0) and underwent right cervical neck dissection. Subsequently, she developed right cervical lymph node relapse and lung metastasis.

Chemotherapy following immune checkpoint inhibitors in recurrent or metastatic head and neck squamous cell carcinoma: clinical effectiveness and influence of inflammatory and nutritional factors.

Objective: This study aimed to evaluate the clinical effectiveness of chemotherapy following immune checkpoint inhibitors (ICI). The association between inflammatory and nutritional factors and prognosis has also been investigated.

Methods: We retrospectively reviewed the medical records of recurrent or metastatic head and neck squamous cell carcinoma (RMHNSCC) patients who received chemotherapy following ICI therapy.

Recurrent Inferior Laryngeal Nerve Preservation During Thyroid Surgery in a Patient with Right Aortic Arch: A Case Report.

Patients with aortic arch malformations may present with recurrent inferior laryngeal nerve abnormalities that require special attention. Herein, we reported a case of thyroid surgery in a patient with a right aortic arch. The left inferior laryngeal nerve was presumed to be the right inferior laryngeal nerve by confirming the location of the aortic arch and subclavian artery, and the presence of the ductus arteriosus on preoperative computed tomography.

X-linked Agammaglobulinemia Diagnosed Following Bezold's Abscess: A Case Report.

Bezold's abscess is an extracranial complication of otitis media, in which a cervical abscess forms from the mastoid process through an ostial fistula, and is a rare condition in recent years. In this study, we experienced a X-linked agammaglobulinemia, which was discovered due to Bezold's abscess. Case: A 12-year-old boy suffering from recurrent right suppurative otitis media for three months was treated with tympanostomy and oral antibacterial therapy at a local otorhinolaryngology clinic.

Salvage transoral videolaryngoscopic surgery for post-irradiation recurrence of hypopharyngeal carcinoma.

Background: Transoral salvage surgery has the potential to preserve a patient's quality of life. Therefore, we investigated the outcomes, safety, and risk factors for postoperative complications of salvage transoral videolaryngoscopic surgery (TOVS) for recurrent hypopharyngeal carcinoma after radiotherapy (RT) or chemoradiotherapy (CRT).

Methods: This retrospective analysis enrolled patients with hypopharyngeal cancer who had a history of RT or CRT and underwent TOVS from January 2008 to June 2021.

Prognostic Value of Inflammatory and Nutritional Biomarkers of Immune Checkpoint Inhibitor Treatment for Recurrent or Metastatic Squamous Cell Carcinoma of the Head and Neck.

This study aimed to determine the prognostic value of inflammatory and nutritional biomarkers of immune checkpoint inhibitor (ICI) therapy for recurrent or metastatic squamous cell carcinoma of the head and neck (RMHNSCC) and to identify the most useful factor for prognosis assessment. We retrospectively reviewed the medical records of patients with RMHNSCC who received ICI therapy. The response rate for ICI therapy and the relationship between inflammatory and nutritional biomarkers and overall survival were examined.

A Study of Patients with Recurrent or Metastatic Head and Neck Cancer Treated with Pembrolizumab.

Background/aim: In December 2019, pembrolizumab was approved in Japan for the treatment of head and neck cancer with recurrence or distant metastasis, making it a new option for first-line treatment. However, there are still many unanswered questions about Overall survival (OS), Progression free survival (PFS), adverse events including immune-related adverse events (irAEs), and biomarkers.

Aims/objectives: The aim of this study was to retrospectively review first-line treatment of head and neck cancer with recurrence or distant metastasis treated with pembrolizumab and to determine whether Combined positive score (CPS) is still useful as a biomarker in the clinical practice.

A p16 Positive M1 Oral Tongue Cancer Completely Responsive to the EXTREME Regimen: A Case Report.

Methods: A 42-year-old woman presented to our clinic with tongue pain and dysarthria. She had a smoking history of 22 pack-years and no history of alcohol consumption. A deep ulcer at the left side of the tongue and induration across the whole tongue were observed.

Avoidance of postoperative irradiation for cervical lymph node metastases of human papillomavirus-related tonsillar cancer.

Background: everal reports have suggested that selected patients with human papillomavirus-related oropharyngeal cancer can be managed with surgery alone. We retrospectively reviewed tonsillar cancer cases to analyze treatment de-intensification after transoral resection.

Methods: Eighteen patients with tonsillar cancer who had undergone transoral resection were included.
