Intranasal Phototherapy in the Patients with Perennial Allergic Rhinitis

BACKGROUND AND OBJECTIVES: Phototherapy has a profound immuno- suppressive effect and is widely used for the treatment of immune- mediated skin diseases. The purpose of this study was to investigate the effectiveness of intranasal phototherapy in treating patients with perennial allergic rhinitis. MATERIALS AND METHODS: We conducted a study on 19 patients with perennial allergic rhinitis from January 2008 to July 2008. Each intranasal cavity was illuminated three times in the first week and then once a week the following five weeks. Symptom scores and Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ) were assessed. RESULTS: Phototherapy was well tolerated by the patients and resulted in a significant improvement of clinical symptoms for rhinorrhea, nasal obstruction, nasal itching, sneezing and total nasal score. In addition, significant improvements were achieved for itching of eyes, itching of the palate and total non-nasal symptom score except tearing and redness of eyes. After six weeks, the overall RQLQ scores significantly improved by 51% from the baseline in the treatment. CONCLUSION: These Results suggest that phototherapy is an effective modality for treating clinical symptoms of perennial allergic rhinitis and represents an alternative treatment for perennial allergic rhinitis.

Isolated Inverted Papilloma of the Sphenoid Sinus Presenting as Ptosis

Inverted papilloma is a rare form of a benign sinonasal tumor characterized by a potentially invasive nature. The lateral nasal wall represents the most common site of origin. In contrast, involvement of sphenoid sinus is exceedingly rare. The present study describes a case of a 52-years-old patient with an inverted papilloma which originated from the sphenoid sinus. The patient complained mainly of headache, ptosis and diplopia. Radiologic study revealed that the sphenoid sinus was completely occupied by the tumor. Additionally, the ethmoid sinus, cavernous sinus and intracranial fossa have been invaded by the tumor. Endoscopic sinus surgery and postoperative radiotherapy were performed. Two months after the operation, the patient has not revealed any new symptom. However, a remnant of the inverted papilloma still remains. The clinical presentation of the inverting papillomas confined to the sphenoid sinus is often non-specific and insidious, with ptosis and diplopia being predominant. The rhinologic surgeon has to rule out this condition.

A Study for the Characteristic Frequency of Korean Disyllabic Word List / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: Speech audiometry is a useful test for obtaining practical information which could not be gotten from the pure-tone audiometer test. Nowadays, Hahm's Korean disyllabic word lists are the most commonly used word lists for the speech reception threshold test in Korea. The disyllabic word lists should be composed of spondaic words (equally stressed words). The aim of this study is to evaluate the characteristic frequency of Hahm's disyllabic word lists. SUBJECTS AND METHOD: Two of the Hahm's disyllabic word lists were evaluated. The word lists were analyzed using an acoustic analysis program that has the MATLAB function. RESULTS: The percentage of disyllabic words in the Hahm's disyllabic word lists that had the spondaic words pattern were 33%. The characteristic frequencies of these words were equally stressed above 1,000 Hz. Other disyllabic words showed an unequally stressed pattern. The percentage of words that had the first syllable stressed pattern was 31% and the percentage of second syllable stressed pattern was 36%. CONCLUSION: Some words, which are commonly used in the Hahm's disyllabic words lists, had an unequally stressed pattern. A new Korean dissyllabic word list needs to use more balanced words that have the characteristic frequency of each word.

A Study for the Acoustic Characteristics of PB Word List according to Frequency / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: The Korean phonetically balanced (PB) word list (Ham's Korean PB Word List) is currently the most commonly used word list for speech discrimination test. The aim of this study was to investigate the frequency characteristics of the Ham's Korean PB word list and to compare frequency characteristics of the Ham's Korean PB word list with that of the 21st Century Sejong words, which represent characteristics of the contemporary spoken Korean language. SUBJECTS AND METHOD: The 300 syllables most commonly used were collected from the words in 21st Century Sejong project. The 21st Century Sejong words were weighted according to the frequency of usage. The 21st Century Sejong words and words from the Ham's Korean PB word list were analyzed using an acoustic analysis program that has the MATLAB function. RESULTS: Syllables with frequencies above 2,000 Hz comprise 34% of the 21st Century Sejong words and 16% of the Ham's Korean PB word list. The Ham's Korean PB word list does not represent the high frequency characteristics of the contemporary spoken Korean language. The 21st Century Sejong words have more 'eu', 'i' and open syllables than the Ham's Korean PB word list. CONCLUSION: The Ham's Korean PB word list does not reflect the high frequency characteristics of the contemporary spoken Korean language included in the 21st Century Sejong words. Therefore, a new PB word list that incorporates a greater number of syllables with high frequency characteristics is required.
