주관적 음성평가는 음향분석기기를 이용한 객관적 음성 평가와 함께 음성분석에 유용하고 의미있는 평가방법이며 현재 알려진 검시법정 중에서 GRBAS 음성평가, VHI, patient self-perceptual voice rating이 가장 널리 사용되고 있고 인정받는 방법이다. 주관적 음성평가는 음성의 상태를 모두 대변할 수은 없으며 객관적인 음성평가에 대한 보완적인 의미를 가진다. 현재 개발되어 있는 주관적 음성평가 방법들이 유용한 평가도구이긴 하지만 나름대로의 문제점과 제한점을 가지고 있기 때문에 이에 대한 개선과 보완을 위한 지속적인 연구와 개발이 요구된다.

Laryngopharyngeal reflux (LPR) is the retrograde movement of gastric contents into the larynx, pharynx, and upper aero-digestive tract. LPR differs from gastroesophageal reflux in that it is often not associated with heartburn and regurgitation symptoms. Otolaryngological manifestations of acid reflux include a wide range of pharyngeal and laryngeal symptoms. Belafsky et al. developed a useful self-administered tool, the reflux symptom index (RSI), for assessing the degree of LPR symptoms. Patients are asked to use a 0 to 5 point scale to grade the following symptoms: 1) hoarseness or voice problems; 2) throat clearing; 3) excess throat mucus or postnasal drip ; 4) difficulty swallowing; 5) coughing after eating or lying down; 6) breathing difficulties ; 7) troublesome or annoying cough; 8) sensation of something sticking or a lump in the throat; 9) heartburn, chest pain, indigestion or stomach acid coming up. A RSI score greater than 13 is considered abnormal. As there is no validated instrument to document the physical findings and severity of LPR, Belafsky et al. developed an eight-item clinical severity scale for judging laryngoscopic finding, the reflux finding score (RFS). They rated eight LPR-associated findings on a scale from 0 to 4 : subglottic edema, ventricular obliteration, erythema/hyperemia, vocal-fold edema, diffuse laryngeal edema, posterior commissure hypertrophy, granuloma/granulation tissue, and thick endolaryngeal mucus. A RFS score of greater than 7 was found to suggest LPR-associated laryngitis. Although both indices (RSI and RFS) are widely used, there is some controversy about their validity (sensitivity and specificity) and reliability (intra-rater and inter-rater) in LPR diagnosis and treatment. We discuss the validity and reliability of RSI and RFS with literature review.

Background and Objectives:The objective of this study was to investigate the features of post-thyroidectomy subjective voice disorder by Voice Handicap Index (VHI) and Voice Symptom Scale (VOISS) through aerodynamic analysis and to investigate the appropriate voice therapy intervention. Materials and Methods:Twenty post-thyroidectomy patients who had no recurrent laryngeal nerve paralysis through laryngeal stroboscopy were enrolled for this study. Acoustic and aerodynamic evaluations were performed before operation, 2 weeks and 3 months after operation. Subjective voice evaluation was performed by VHI and VOISS. Aerodynamic evaluation was compared and analysed by maximum phonation time(MPT), phonation threshold pressure(PTP), mean air flow rate(MFR), etc. Subjective voice evaluation was surveyed through VHI and VOISS. To evaluate patients' symptoms related to functional voice disorder, scores on physical domain in VHI and VOISS were selected to be compared for each session. Results: The 10 out of 20 participants who complained of voice symptoms had no significant difference with pre-operation in acoustic evaluation, but all showed higher scores on 2 weeks and 3 months after operation compared to pre-operation, in VHI-physical domain and selected questionnaires in VOISS. They reduced MPT and increased PTP value simultaneously. Laryngeal massage and breathing training were simultaneously treated to them, 5 participants resulting in improvement in MPT and PTP compared to pre-treatment. Conclusion:Patients who complained voice change with no organic damage after thyroidectomy were all shown to have reduced MPT and increased PTP in some by aerodynamic evaluations. Reduced MPT may imply some problem in air flow beneath glottis. Increased PTP suggests much more effort in vocalization mechanism than pre-operation. Comparing aerodynamic evaluations in post-thyroidectomy may provide information on behavioral interventions. Additionally, study on laryngeal massage and breathing training simultaneously treated to patients with such voice disorder is needed to be conducted with larger number of participants.

In the treatment of spasmodic dysphonia, local injection of botulinum toxin A has been reported to be successful. The treatment of adductor type spasmodic dysphonia with botulinum toxin type A injection using a flexible nasopharyngoscope was conducted in 29 patients and using a telearyngoscope in 31 patients. These patients were given toxins in the vocal fold(s), unilaterally or bilaterally, under flexible nasopharyngoscopic guidance with sclerosing needle or telelaryngoscopic guidance with 23 gauge scalp needle attached by laryngeal forceps. Before the above procedure, laryngeal anesthesia was done with 2% pontocain instillation. Among the 60 patients, 59 patients were given the toxin successfully. Telephone interview were made at 2weeks and then at 4 weeks post injection. Among 29 patients using a flexible nasopharyngoscope, 75.8% and among 31 patients using a telelaryngoscope, 90.0% reported that the patients' symptom was improved. The functional status of the patient's disorder was classified into four grades. The mean pre-injection grade fir the patients using flexible nasopharyngoscope and telelaryngoscope was 1.6 and 2.1 respectively. And it was lowered to 0.7 and 1.1 respectively after the injection. The result was similar(p<0.05). As a self assessment method, the patients were asked to rate their voice on a scale of 100. In this study, the mean pre-injection score was 44 and 40 respectively. And it was improved to 77.7 and 69.8 respectively after the injection. The result was similar(p<0.05). In conclusion, botulinum toxin injection using a flexible nasopharyngoscope is also an effective method for the treatment of adductor type spasmodic dysphonia as using a telelaryngoscope.

In the treatment of spasmodic dysphonia, laryngeal injection of botulinum toxin has been reported to be successful. The treatment of adductor type spasmodic dysphonia with botulinum toxin type A injection using EMG was conducted in 24 patients and it's effect was compared with results from flexible nasopharyngoscopy guided injection(29 patients) and telelaryngoscopy guided injection(31 patients). Sixty two point five percent(62.5%) of patients using EMG and 75.8% of patients using flexible nasopharyngoscope and 90.0% of patients using telelaryngoscope reported that the patient's symptom was improved. The functional status of the patient's disorder was classified into low grades. The mean pre-injection grade for patients using EMG, flexible nasopharyngoscope and telelaryngoscope was 1.7, 1.6 and 2.1 respectively. And it was lowered to 1.0, 0.7 and 1.1 respectively after the injection. Results were similar(p＜0.05). As a self assessment method, patients were asked to rate their voice on a scale of 100. In this study, the mean pre-injection score was 66.3, 44.0 and 40.0 respectively. And it was improved to 74.8, 77.7 and 69.8 respectively after the injection. Among 23 patients who undergone above 3method, 17 patients(73.9%) told that EMG-guided botulinum injection was preferable method in its convenience and effectiveness. In conclusion, EMG guided botulinum toxin injection is an another effective method for the treatment of adductor type spasmodic dysphonia similar to telelaryngoscopy-guided injection and flexible nasopharyngoscopy guided injection.

Purpose: The coronavirus disease 2019 (COVID-19) pandemic has had significant physical and psychological impacts on registered nurses (RNs). This study aimed to identify long COVID symptoms and their associated factors specifically among RNs. Methods: This descriptive correlational study's sample comprised 189 nurses (31.57±5.98 years, 93.7% female) in Korea. Self-reported long COVID symptoms were assessed using the COVID-19 Yorkshire Rehabilitation Scale. Data were collected from December 31, 2022, to January 13, 2023, using the online survey method and were analyzed using independent t-test, Wilcoxon signed-rank test, one-way ANOVA, Pearson's correlation, and a multiple linear regression analysis with the IBM SPSS Statistics 26.0 program. Results: A total of 179 participants (94.7%) experienced one or more long COVID symptoms. The most prevalent symptoms were weakness (77.8%), fatigue (68.3%), breathlessness (67.7%), cough/throat sensitivity/voice change (50.3%), and sleep problems (50.3%). The factors related to long COVID symptoms were marital status, type of institution, working time, acute COVID-19 symptoms, and vaccination status. The quarantine period (β=.26, p<.001) and the nursing workforce after COVID-19 (β=-.17, p=.018) were significantly associated with long COVID symptoms (Adjusted R² =.33). Conclusion: Providing comprehensive recognition is necessary for the understanding of long COVID symptoms and their associated factors among nurses and could promote a long COVID symptom management education program targeted at nurses. Moreover, it could facilitate effective nursing care and education plans for long COVID patients.

The reason that aromatherapy began to draw attention again as the alternative therapy is because the essential oils that are used for aromatherapy not only allow the human body to maintain homeostasis but also have an effect on curing a mental feeling of fatigue and because these efficacies and effects are proceeding with being proved scientifically. Also, with coming to be high in a voice of concern about severally side effects that the modern medicine and the synthetic chemistry have, the aromatherapy came to be paid attention as the replacement therapy that can substitute for and supplement this. In particular, at the time of requiring a study on a substance to substitute for this after having been announced in Japan for 1998 a risk of Zincpyrithione that is being used as a component of dandruff treatment, it is thought that the aroma oil that was known for having an anti-dandruff effect has a merit of being easy in a user's access, thus it will be effective in curing the symptom of dandruff. Accordingly, this study conducted the following experiment in a bid to examine whether the aroma oil has the anti-microbial effect on the actual malassezia. First of all, it measured the minimum concentration of aroma oil in which the growth of malassezia is inhibited, by carrying out MIC(Minimum Inhibition Concentration) test in terms of anti-microbial activity against Malassezia furfur KCTC 7744 while using oils of Patchouli, Rosemary, Lavender, and Tea tree among aroma oils that are being used for dandruff treatment. As a result of that, Tea tree oil has the most excellent anti-microbial activity, and the measurement result of anti-microbial activity was shown in order of Lavender oil>Rosemary oil>Patchouli oil. Next, it carried out the is actually eased by applying Tea tree oil directly to the scalp of dandruff. In consequence of the experiment, the massage of Tea tree oil indicated the result of relieving the symptoms of dandruff such as scale, itch, pain, inflammation, and sebum, and among these symptoms of dandruff, it was shown to be most effective in easing itch. Especially, this clinical experiment was indicated that the massage of Tea tree oil has the most effect on relieving itch of targets with a dry-skin type who had no experience of dandruff treatment.
