RESUMO
Background and Objectives@#A lack of investigators for polysomnography has risen due to increased demand since health insurance started to cover the cost of the test. We examined the reliability of the automated scoring of polysomnography, which has been deployed to improve this imbalance.Subjects and Method We analyzed the data of 20 patients who underwent level 1 polysomnography from April 1 to July 27, 2019. The software from Noxturnal (Nox Medical) was used for the scoring of the Polysomnography data. Each of the polysomnographic data was scored both by the automated scoring system and by a skilled technician. @*Results@#Twenty patients were analyzed. There was no significant difference between automated scoring and manual scoring in sleep latency, apnea index, and rapid eye movement sleep stage ratio. However, the concordance rate of the sleep stage by epoch was 83.32%, and there was a significant difference with regards to apnea-hypoapnea index (AHI) and respiratory disturbance index (RDI). Two obvious errors were noted in the automated scoring that could be easily fixed; the failure to recognize wakefulness during sleep and the fragmentation of respiratory events. When two errors were corrected, many differences in polysomnography parameters, including AHI and RDI, were eliminated. @*Conclusion@#It showed 80% coincidence of epoch in the sleep stage between the automated scoring and manual scoring. However, there was no difference in AHI and RDI when the fragmented respiratory events of the automated scoring were adjusted. Therefore, automated scoring is considered to be useful if only a little modification could be made.
RESUMO
Laryngeal foreign body can be a life-threatening emergency. Respiratory distress, aphonia, and cyanosis may occur in quick succession. However, in case of a non-obstructive laryngeal foreign body, symptoms can be indolent, but the hazardous foreign body can nevertheless put the patient in danger. To prevent life-threatening consequences, early detection based on symptoms is imperative. This case, which presented with usual symptoms of anterior neck pain and throat discomfort without respiratory symptoms and an unusual site of laryngeal foreign body, finally turned out to be an impacted fish bone in the subglottis.

BACKGROUND AND OBJECTIVES@#Chronic rhinitis is divided into allergic rhinitis (AR) and nonallergic rhinitis (NAR), both of which have similar symptoms but differ in treatment approaches. For the diagnosis of AR, allergen-specific immunoglobulin E (IgE) tests along with characteristic symptoms are required. However, these tests are costly and not always practicable. The purpose of this study was to investigate how symptoms respond differently to different allergen sensitization or sensitized allergen.SUBJECTS AND METHOD: We retrospectively reviewed 1661 patients who underwent multiple allergen simultaneous test (MAST) for chronic rhinitis symptoms. The total nasal symptom (TNS) scores of these patients from 2006 to 2014 were assessed for rhinorrhea, nasal obstruction, itching, and sneezing. Patients were classified as AR and NAR according to the results of MAST and their association with symptoms.@*RESULTS@#There were 1021 patients designated to the AR group and 640 patients to the NAR. The AR group had lower age, higher TNS, and higher serum IgE levels than the NAR group. In addition, sneezing and itching were more common in the AR group. Furthermore, sneezing was a positive predictor for seasonal allergen sensitization. On the other hand, itching was a positive predictor for perennial allergen sensitization.@*CONCLUSION@#AR and NAR patients showed different demographic characteristics and symptoms. These results may be helpful in classifying and treating patients with chronic rhinitis, especially when the allergen specific IgE test cannot be performed.

A congenital cholesteatoma is a benign mass formed from the keratinizing stratified squamous epithelium. It usually occurs in young children's anterosuperior part of the middle ear. A congenital cholesteatoma which originates from mastoid temporal bone or expands to posterior cranial fossa is rare. Standard treatment of an intracranial cholesteatoma is surgical removal with craniotomy. A 69-year-old woman was diagnosed with a congenital cholesteatoma of mastoid temporal bone that expanded to the posterior cranial fossa, which was successfully treated with transmastoid marsupialization without craniotomy. This is a first documented case of a congenital cholesteatoma of mastoid temporal bone that expanded to posterior cranial fossa, which was successfully treated with transmastoid marsupialization without craniotomy.

BACKGROUND AND OBJECTIVES: Although canal wall up mastoidectomy (CWUM) has been performed frequently as a treatment for chronic otitis media (COM), the necessity of CWUM for non-cholesteatomatous COM (NCCOM) is still controversial. Since elderly people often have systemic problems, there is a high likelihood of side effects after general anesthesia, so it is important to judge the necessity of mastoidectomy. The purpose of this study was to investigate the effect of CWUM for the treatment of NCCOM in patients over 65 years of age. SUBJECTS AND METHOD: Forty-two cases of CWUM with tympanoplasty type I performed as a treatment for NCCOM from 2007 through 2016 were reviewed retrospectively. Pure tone audiometry was performed preoperatively and postoperatively, and preoperative temporal bone CT was used to evaluate the mastoid status. The valsalva maneuver (VM) was used to evaluate the eustachian tube function. RESULTS: The total number of patients was 42 and the success rate of eardrum repair was 92.8%. Comparison of hearing results taken preoperatively and postoperatively showed significant hearing improvement in both air conduction and air-bone gap. When hearing results were compared according to the mastoid status and the response of VM, there were no significant differences. CONCLUSION: Mastoidectomy combined with tympanoplasty type I showed a high success rate of ear drum repair and good hearing improvement, with no critical side effects. Therefore, mastoidectomy does not need to be limited by one's old age. Adequate mastoidectomy after proper consideration of the mastoid status will be helpful in the treatment of the disease.

BACKGROUND AND OBJECTIVES: Sudden sensorineural hearing loss (SSNHL) in children can occur just as can in adults; in fact, it may last throughout the entire life of a child, affecting the individual much more than when it does to an adult. As there are only a few studies that have focused on SSNHL in childhood, we investigated the clinical characteristics and hearing outcomes of pediatric SSNHL. SUBJECTS AND METHOD: A retrospective review of patients from November 2005 to May 2014 was carried out. Thirty nine patients under the age 15, who were hospitalized due to SSNHL were enrolled. Of these patients, 226 patients over the age of 15 were collected as a comparison group. Age, sex, underlying disease, site of hearing loss and duration from the onset to treatment were analyzed. We evaluated the overall recovery rate as well as the recovery rate according to accompanying diseases. RESULTS: Recovery rates were comparable between the pediatric and the adult group. Overall recovery rate was 60% in the pediatric group. Unlike for the adult group, dizziness and tinnitus were not a prognostic factor in the pediatric group. Pediatric patients showed similar overall recovery, whether the treatment initiation was under 7 days or more. Recurrence was seen in 3 patients, of which 2 showed complete recovery. CONCLUSION: The recovery rate for SSNHL was similar for the pediatric and the adult groups. A higher recurrence rate may alert clinicians to be aware of hearing changes after the recovery in pediatric patients.
