First Report of Klebsiella pneumoniae subsp. ozaenae Meningitis in Japan.

Although the frequency of community-acquired infections caused by Klebsiella pneumoniae subsp. ozaenae (K. ozaenae) is low, they are often detected in sputum specimens.

Preventive effects of skin protectants on the development of medical device-related pressure wounds in endoscopic sinonasal surgery.

Objectives: Medical device-related pressure ulcer (MDRPU) is a skin or subcutaneous tissue injury caused by medical devices. Skin protectants have been used to prevent MDRPU in other fields. In endoscopic sinonasal surgery (ESNS), rigid endoscopes and forceps can cause MDRPU; however, detailed investigations have not been conducted.

Characteristics of Nasal Foreign Bodies and Equipment on Complications During Removal Procedures.

Objective: The treatment of nasal foreign bodies involves safe and reliable removal. Few reports have investigated the relationship between equipment and the incidence of complications.

Methods: This retrospective study included 300 patients with nasal foreign bodies (average: 3.

A Covered Lateral and Posterior Wall Flap of the Maxillary Sinus Prevents Reocclusion of the Postoperative Maxillary Cyst.

Unlabelled: Although the number of postoperative maxillary cyst (POMC) cases has declined recently, a few reports of refractory cases have also been reported. The indications for endoscopic sinus surgery (ESS) for POMC removal are broadening and attempts to prevent postoperative recurrence at the cyst opening site have been widely investigated. Here, we have advocated our original pedunculated mucoperiosteal flap (CLAP flap; covered lateral and posterior wall flap of the maxillary sinus), where the bony area exposed intraoperatively is covered, to prevent postoperative recurrence.

Clinical Diagnosis of Central Vertigo in Patients With Dizziness in Emergency Practice.

Background: Life-threatening diseases should be promptly identified to provide appropriate medical care for emergency outpatients experiencing dizziness. However, dizziness is associated with various medical conditions; thus, a definitive diagnosis is challenging. To accurately diagnose vertigo in an emergency outpatient, we conducted a survey on the need to identify vertigo patients in the current outpatient departments.

Effects of Hangeshashinto on the nasal physiological function: An in vitro study.

Objective: Hangeshashinto is a Japanese Kampo medicine applied for the treatment of oral mucositis and gastroenteritis. Hangeshashinto exhibits broad-spectrum antibacterial activity and suppresses prostaglandin (PG)E2 production in the mucosa and has the ability to improve the inflammatory condition. In addition to these effects, because cAMP, a composition of Hangeshashinto, facilitates ciliary beat, Hangeshashinto could also improve the physiological function of the nasal mucosa, consist of ciliated epithelium, but details were unknown.

Effect of gauze placement soaked with adrenaline at suprabullar recess on hemostasis during endoscopic sinus surgery: A randomized controlled trial.

Background: Topical application of vasoconstrictors is necessary for endoscopic sinus surgery (ESS) for a bloodless surgical view and reduced intraoperative bleeding. We aimed to verify the effectiveness of gauze placement soaked with adrenaline at suprabullar recess, where the anterior ethmoidal artery exists, on hemostasis during ESS.

Methods: A randomized, double-blinded trial was carried out for 26 patients receiving ESS.

Pathological Features of Free Graft and Pedicled Flap in the Nasal Cavity: An Animal Study.

Objectives/hypothesis: Recent developments in reconstructive techniques for mucosal defects using mucoperiosteal materials have enabled rapid recovery of physiological function after endoscopic sinus surgery. Clinical trials have described the advantages, disadvantages, and different outcomes of free graft and pedicled flap, which, respectively, sacrifice or preserve blood flow. However, histological changes, that affect the postoperative outcomes after reconstruction, remain unclear.

Predictors of Visual Acuity and Usefulness of a Treatment Algorithm in Rhinogenous Optic Neuritis.

Rhinogenous optic neuritis, which causes neuropathy associated with visual dysfunction, greatly reduces patient quality of life and requires suitable early treatment. This study aimed to analyze visual outcome predictors in patients with rhinogenous optic neuritis and to develop and investigate the usefulness of an algorithm to facilitate early treatment. Prospective and retrospective investigations were conducted at the Department of Otorhinolaryngology.

Effect of a Superior Lateral Anterior Pedicle Flap for Draf Procedures.

Several types of flap techniques have been developed to cover exposed bone after Draf procedures to reduce the possibility of re-stenosis. These techniques are relatively new and detailed measurements of the size of neo-Ostia during follow-up have not been reported. The authors aim to assess outcomes precisely by not only using endoscopic evaluation but also by measuring the diameter of the ostium and the thickness of the nasal beaks on pre- and postoperative computed tomography images.
