Aspirin use reduces cancer risk in betel nut chewers: a nationwide population-based cohort study.

Betel nut chewing, common in several Asian populations, is linked to increased cancer risk, including oral, esophageal, gastric, and hepatocellular carcinoma. Aspirin shows potential as a chemopreventive agent. This study investigates the association between aspirin use and cancer risk among betel nut chewers.

Effect of Preexisting Sarcopenia on Acute and Late Postoperative Pneumonia Among Patients With Oral Cavity Squamous Cell Carcinoma.

Background: Whether preexisting sarcopenia is an independent risk factor for postoperative pneumonia (POP) for patients with oral cavity squamous cell carcinoma (OCSCC) remains unclear. Therefore, we conducted a propensity score-matched population-based cohort study to compare the risk of acute and late POP for patients with sarcopenic and nonsarcopenic OCSCC who underwent curative surgery.

Patients And Methods: We included patients with OCSCC who underwent curative surgery and categorized them into 2 groups depending on whether they had preexisting sarcopenia.

Survival effect of pretreatment FDG-PET-CT on nasopharyngeal cancer.

Background/purpose: Accurate staging is the first step for optimal treatment selection in patients with nasopharyngeal carcinoma (NPC). In this propensity-score-matched, population-based cohort study, we investigated the survival effects of pretreatment 8-fluorodeoxyglucose positron emission tomography-computed tomography (FDG-PET-CT) on patients with NPC.

Methods: We included patients with stage I-IVA NPC receiving radiotherapy or concurrent chemoradiotherapy and categorized them into two 1:1 propensity score-matched groups according to whether or not they underwent pretreatment FDG-PET-CT and compared their outcomes.

The clinical features of endoscopic treated isolated sphenoid sinus diseases.

Background: Isolated sphenoid sinus disease (ISSD) is a rare clinical entity with potentially serious complications. The etiological distribution of ISSD varies among different areas and ethnicities. We aimed to investigate the clinical features of patients with endoscopic treated ISSD.

Acute hearing loss in patients with hematological disorders.

Objective: This study adopted an inner ear test battery to investigate the causes of acute sensorineural hearing loss in patients with hematological disorders.

Methods: During the past 20 years, the authors have experienced 14 patients with hematological disorders, i.e.

Allergic fungal otomastoiditis: a case report.

Allergic mucin is described as thick, peanut butter-like mucus impacted in the paranasal sinuses of patients with allergic fungal rhinosinusitis. The presence of allergic mucin in the middle ear has never been reported. We encountered a 65-year-old female with allergic mucin found impacted in her left middle ear and mastoid cavity during revised tympanoplasty surgery at our institute.

Toxoplasma IgG expressed in a patient with Rosai-Dorfman disease.

Rosai-Dorfman Disease (RDD) is a rare benign disease characterized by sinus histiocytosis with massive lymphadenopathy. RDD can be differentiated from other types of histiocytosis by immunochemical analysis, as RDD is positive for S100. Conversely, toxoplasmosis lymphadenitis is characterized by clusters of epithelioid histiocytes in lymphoid tissue, with mixed lymphocytic and immunoblastic cell populations.

Herpes zoster laryngis with prelaryngeal skin erythema.

A 74-year-old man came to our hospital with complete left vocal cord paralysis and erythema of the prelaryngeal skin. The patient also had mucosal swelling and erosions in the left arytenoid cartilage, aryepiglottic fold, and pyriform sinus. Herpetic vesicles developed over the prelaryngeal erythema 4 days after admission.

Acute effects of alcohol on auditory thresholds and distortion product otoacoustic emissions in humans.

Objective: To investigate the acute effects of alcohol consumption on pure-tone thresholds (PTs) and distortion product otoacoustic emissions (DPOAEs) in humans

Material And Methods: Eight healthy adults were asked to drink alcohol to the clinical intoxication level. PTs and DPOAEs were determined serially before and after alcohol ingestion.

Results: Alcohol had no effect on PTs DPOAE amplitudes above 5500 Hz dropped 30 min and 1 h after alcohol ingestion, returning to the pre-test level 2 h after ingestion.
