ABSTRACT

Objectives@#. Endoscopic tympanoplasty (ET) provides minimally invasive transcanal access to the middle ear and improves middle ear visibility for the treatment of tympanic membrane (TM) perforations. However, the literature on surgical outcomes for large TM perforations is lacking and limited to small series. This study aimed to evaluate the clinical benefits of ET for large TM perforations. @*Methods@#. This retrospective cohort study was conducted at nine tertiary referral hospitals in South Korea, where 252 patients who underwent ET as primary surgery from September 2019 to August 2021 were included. The outcome measures included the graft success rate and pre- and postoperative audiometric data. @*Results@#. In 239 patients, the graft success rate of ET for large or subtotal perforations was 86.2% (206 patients), while the graft failure rate was 13.8% (33 patients). The graft failure rate was directly correlated with surgical techniques, including overlay and medial or lateral underlay tympanoplasty (P=0.027). Lateral underlay tympanoplasty showed the most favorable results. Sex, laterality, etiology, site and size of perforation, operation time, and graft materials did not vary significantly between the graft success and failure groups (P>0.05). The mean air-bone gap (ABG) improved significantly in both groups (graft success group: 10.0±0.6 dB and graft failure group: 7.7±0.3 dB; P<0.001). However, the ABG improvement did not significantly differ between the groups. Analysis of covariance revealed that the postoperative 500-Hz bone conduction threshold improved after successful ET (adjusted coefficient, –11.351; 95% confidence interval, –21.491 to –1.212; P=0.028). @*Conclusion@#. This study involved the largest population to date of large TM perforations treated by ET. The study findings suggest that ET is feasible and effective in treating large TM perforations.

ABSTRACT

Purpose@#: This study aimed to identify the effects of a multifaceted pediatric delirium education program for pediatric intensive care unit (PICU) nurses on their delirium knowledge, confidence in delirium nursing, and delirium evaluation accuracy. @*Methods@#: This study used a one-group pretest-posttest design. The participants were 50 nurses in two units of the PICU at S General Hospital in Seoul. All participants took a 1-hour lecture with case-based practice for the first two weeks, and received feedback as they applied the program to clinical practice over the next two weeks. Test measures were completed before and after the four week intervention period for all participants. The delirium evaluation accuracy was measured using the Korean version of the Cornell Assessment of Pediatric Delirium. Data were analyzed using the chi-square and paired t-tests. @*Results@#: After the Pediatric Delirium Education Program, nurses’ delirium knowledge (x2 =11.65, p =.001), confidence in delirium nursing (t=9.71, p<.001), and delirium evaluation accuracy (t=6.07, p<.001) improved significantly. @*Conclusions@#: Pediatric delirium education programs for PICU nurses were effective. For active application of the program in clinical practice in the future, various cases of childhood delirium and specific strategies for each subject must be developed. To achieve this, long-term intervention and research for multiple organizations are required.

ABSTRACT

Background@#Patient safety is a crucial indicator of health care quality. It is necessary to check the subjective perception of patient safety from the patient’s point of view as a consumer of healthcare services. To identify patients’ experiences of safety and the themes that constitute the patients’ feeling of safety during hospitalization. @*Methods@#A qualitative study, comprising five focus group discussions (seven people each), was conducted in South Korea between May and July 2018. Patients who were hospitalized for at least three days within one year were included. Researchers analyzed the transcribed script, and a content analysis was performed to describe patients’ hospitalized experiences of safety. @*Results@#A total of 35 patients with an average age of 45.4 years participated in the study, and had experience of hospitalization for up to 32 days. The findings revealed four core themes and 14 sub-themes. Patients wanted to take initiative in controlling his/her reception of information and wanted healthcare providers to make the patient feel safe. Patients felt safe when hospitals provided unstinted and generous support. Also, public sentiment about national healthcare and safety made an effect on patient safety sentiment. @*Conclusion@#Patients felt safe during hospitalization not only because of the explanation, attitude, and professionalism of the healthcare providers but also because of the support, system, and procedure of the medical institution. Healthcare providers and medical institutions should strive to narrow the gap in patient safety awareness factors through activities with patients. Furthermore, the government and society should make an effort to create a safe medical environment and social atmosphere.

ABSTRACT

Background and Objectives@#With the growing acknowledgment of age-related vestibular impairments, consensus diagnostic criteria for presbyvestibulopathy (PVP) have been recently published. The PVP criteria retains its objectivity with video head impulse test (vHIT), rotatory chair test (RCT) and caloric test. These objective tests share testing principles, but targeted frequencies vary across the tests. The PVP criteria are applicable for subjects of age over 60. However, there are different age cut-offs for older male in different areas. The purpose of the present study was to explore whether the PVP diagnostic criteria were appropriate for early elderly (Eel) patients and to identify the most sensitive test for age-related loss of vestibular function.Subjects and Method Eligible patients, aged 60 years or older, complained of dizziness for at least 3 weeks, and have undergone at least one of the followings: vHIT, RCT, or caloric test. We selected two groups based on age: the Eel group (aged >60 years but <65 years) and the late elderly (Lel) group (aged ≥75 years). @*Results@#The vestibulo-ocular reflex (VOR) gains differed significantly between the Eel and Lel groups for vHIT and caloric gain test. No Eel patient met the PVP criteria but 26.1% of Lel patients met the criteria for vHIT, and the proportions of such patients in the two groups differed significantly. @*Conclusion@#Eel subjects could be considered to differ from Lel subjects. Given the significance of both averages, VOR difference and the proportional difference in terms of meeting the PVP criteria and vHIT may be optimal when evaluating age-related changes.

ABSTRACT

Background@#In Korea, the safety culture is led by national policy. How the policy ensures a patient safety culture needs to be investigated. This study aimed to examine the way in which physicians and nurses regard, understand, or interpret the patient safety-related policy in the hospital setting. @*Methods@#In this qualitative study, we conducted four focus group interviews (FGIs) with 25 physicians and nurses from tertiary and general hospitals in South Korea. FGIs data were analyzed using thematic analysis, which was conducted in an inductive and interpretative way. @*Results@#Three themes were identified. The healthcare providers recognized its benefits in the forms of knowledge, information and training at least although the policy implemented by the law forcibly and temporarily. The second theme was about the interaction of the policy and the Korean context of healthcare, which makes a “turning point” in the safety culture.The final theme was about some strains and conflicts resulting from patient safety policy. @*Conclusion@#To provide a patient safety culture, it is necessary to develop a plan to improve the voluntary participation of healthcare professionals and their commitment to safety.Hospitals should provide more resources and support for healthcare professionals.

ABSTRACT

Background@#Fecal microbiota transplantation against gut colonization using a multidrugresistant organism is a technique used to treat infections through normalizing the gut microbiota via fecal microbiota transplantation in patients with confirmed colonization by carbapenem-resistant Enterobacteriaceae (CRE) or vancomycin-resistant enterococci (VRE) based on a fecal culture test within the past one week. In this study, we aimed to determinethe safety and effectiveness of this technique. @*Methods@#The safety and effectiveness were assessed via a systematic review. A literature search was conducted using five Korean databases, such as KoreaMed, and international databases, including Ovid-MEDLINE, Ovid-EMBASE, and Cochrane Library. @*Results@#Main results are described here. From the studies retrieved using the aforementioned search strategy, the remaining 581 studies were screened using the inclusion and exclusion criteria, resulting in the selection of nine studies for further consideration. In terms of safety, many studies reported deaths and adverse reactions associated with different causes. Fewer studies reported the rate of colonization; however, the effect of colony rate was inconsistent when compared to no treatment group. Additionally, none of the studies assessed the recurrence rate, a decrease in the prevalence of diseases related to infection by multidrugresistant bacteria, and the quality of life. @*Conclusion@#Fecal bacterial colonization for the decolonization of intestinal multidrugresistant bacteria was evaluated using a technique that requires further research as there is insufficient literature evidence to validate its safety and efficacy in treating infections through normalizing the intestinal flora of patients with confirmed colonization by CRE or VRE.

ABSTRACT

Background and Objectives@#This study aimed to evaluate the clinical features and the clinical factors associated with prognosis of sudden sensorineural hearing loss (SSNHL) in diabetic patients. @*Subjects and Methods@#Forty-nine diabetic with unilateral SSNHL were retrospectively included. All patients received systemic high dose steroid therapy within one month after onset and had more than one month of follow-up audiogram. The basic characteristics of the patients, initial and follow-up audiograms, laboratory data, and methods of steroid treatment were collected. @*Results@#Compared to reference values in healthy subjects, 79%, 55%, and 45% of the patients had higher values of mean neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), and lymphocyte-monocyte ratio (LMR), respectively. Older patients had significantly less degree of hearing loss, but they also had significantly worse hearing thresholds in the unaffected ear. After steroid treatment, less than half patients (47%) showed hearing recovery. Simultaneous intratympanic dexamethasone (ITD) injections with systemic steroid did not confer an additional hearing gain or an earlier recovery rate in diabetic patients with SSNHL. In the multivariate analysis, initial hearing thresholds of affected ear and timing of steroid treatment were significantly associated with hearing prognosis in diabetic patients with SSNHL. @*Conclusions@#Diabetic patients with SSNHL tended to have increased NLR, LMR, and PLR, which are reported to be associated with microvascular angiopathy. Simultaneous ITD injections to improve hearing recovery in diabetic patients with SSNHL seems unnecessary.

ABSTRACT

Background and Objectives@#Non-linear frequency compression (NLFC) technology compresses and shifts higher frequencies into a lower frequency area that has better residual hearing. Because consonants are uttered in the high-frequency area, NLFC could provide better speech understanding. The aim of this study was to investigate the clinical effectiveness of NLFC technology on the perception of speech and music in patients with high-frequency hearing loss. @*Subjects and Methods@#Twelve participants with high-frequency hearing loss were tested in a counter-balanced order, and had two weeks of daily experience with NLFC set on/off prior to testing. Performance was repeatedly evaluated with consonant tests in quiet and noise environments, speech perception in noise, music perception and acceptableness of sound quality rating tasks. Additionally, two questionnaires (the Abbreviated Profile of Hearing Aid Benefit and the Korean version of the International Outcome Inventory-Hearing Aids) were administered. @*Results@#Consonant and speech perception improved with hearing aids (NLFC on/off conditions), but there was no significant difference between NLFC on and off states. Music perception performances revealed no notable difference among unaided and NLFC on and off states. The benefits and satisfaction ratings between NLFC on and off conditions were also not significantly different, based on questionnaires, however great individual variability preferences were noted. @*Conclusions@#Speech perception as well as music perception both in quiet and noise environments was similar between NLFC on and off states, indicating that real world benefits from NLFC technology may be limited in Korean adult hearing aid users.

ABSTRACT

Objectives@#. Endoscopic pituitary surgery usually requires a collaboration between neurosurgeons and ENT surgeons to achieve optimal outcomes. However, neurosurgeons occasionally perform these procedures alone without an ENT surgeon. In this study, postoperative sinonasal quality of life and olfactory function were compared in patients who underwent endoscopic pituitary surgery performed by a single neurosurgeon or by a collaborative team of a neurosurgeon and an ENT surgeon. @*Materials and Methods@#. A retrospective review of prospectively collected data was performed. Patients who underwent endoscopic pituitary surgery for pituitary adenoma from January 2015 to April 2018 were included. The study patients were divided into two groups; patients in group 1 underwent surgery performed by a single neurosurgeon, while patients in group 2 received surgery performed by a collaborative team of surgeons. Olfaction was assessed using a subjective Likert scale, the Cross-Cultural Smell Identification Test (CC-SIT), and the butanol threshold test (BTT). In addition, patients answered the Sino-nasal Outcome Test (SNOT-22) questionnaire regarding sinonasal quality of life before and 3 months after surgery. @*Results@#. This study included 152 patients (46 patients in group 1 and 106 patients in group 2). Significant differences were not observed between the two groups regarding age, sex, tumor size, or operation time. Although subjective olfaction was not significantly different before and after surgery, group 2 showed significantly better objective olfactory function based on the CC-SIT (8.44±3.00 vs. 9.84±1.40; P=0.012) and BTT (4.67±0.84 vs. 5.02±0.33; P=0.022) scores at 3 months after surgery. The SNOT-22 scores were not statistically significantly different between the two groups (P>0.05). @*Conclusion@#. In the present study, better olfactory outcomes were observed in patients who underwent surgery performed by a collaborative team of a neurosurgeon and an ENT surgeon. This result shows the need for collaboration between neurosurgeons and ENT surgeons in endoscopic pituitary surgery.

ABSTRACT

PURPOSE: We investigated the expression of the N-myc and STAT interactor (NMI) protein in invasive ductal carcinoma tissue and estimated its clinicopathologic significance as a prognostic factor. The expression levels and prognostic significance of NMI were also analyzed according to the molecular subgroup of breast cancers.METHODS: Human NMI detection by immunohistochemistry was performed using tissue microarrays of 382 invasive ductal carcinomas. The correlation of NMI expression with patient clinicopathological parameters and prognostic significance was analyzed and further assessed according to the molecular subgroup of breast cancers. Moreover, in vitro experiments with 13 breast cancer cell lines were carried out. We also validated NMI expression significance in The Cancer Genome Atlas cohort using the Human Protein Atlas (HPA) database.RESULTS: Low NMI expression was observed in 190 cases (49.7%). Low NMI expression was significantly associated with the “triple-negative” molecular subtype (p < 0.001), high nuclear grade (p < 0.001), high histologic grade (p < 0.001), and advanced anatomic stage (p = 0.041). Patients with low NMI expression had poorer progression-free survival (p = 0.038) than patients with high NMI expression. Low NMI expression was not significantly associated with patient prognosis in the molecular subgroup analysis. In vitro, a reduction of NMI expression was observed in 8 breast cancer cell lines, especially in the estrogen receptor-positive and basal B type of triple-negative breast cancer molecular subgroups. The HPA database showed that low NMI expression levels were associated with a lower survival probability compared with that associated with high NMI expression (p = 0.053).CONCLUSION: NMI expression could be a useful prognostic biomarker and a potential novel therapeutic target in invasive ductal carcinoma.

ABSTRACT

Foreign bodies in the sinus are rare entities that are often associated with trauma. This paper presents a case of a metallic foreign body that was retained without any symptoms for over 40 years. A skull X-ray and computed tomography scans showed blades of scissors inside the maxillary sinus, extending to the middle meatus without affecting vital structures. The foreign body was successfully removed by an endoscopic approach. There were no complications during and after the surgery. The presence of retained foreign bodies in the maxillofacial region is rarely discussed in previous publications. This manuscript focuses on the asymptomatic period of this foreign body and aims to discuss the necessity and feasibility of a wait-and-see approach in selected cases.

ABSTRACT

Purpose@#Carbapenemase-producing Enterobacteriaceae (CPE) are associated with considerable mortality. This study was aimed to identify survival factors among medical care unit patients with CPE. @*Methods@#We conducted a retrospective cohort; data were collected from September 2017 to June 2019 through electronic medical records. The data collected were general characteristics, disease-related characteristics, severity-related characteristics, and treatment-related characteristics. Data were analyzed based on frequency, mean, standard deviation, Chi-square test, Fisher’s exact test, t-test, Pearson’s correlation coefficient, and Cox proportional hazard model using SPSS/WIN 21.0 program. @*Results@#Seventy-seven patients were included (59 survivors and 18 deceased) in the study. Univariate analysis identified factors for survival associated with acquired CPE as age (t= -1.56, p= .037), simplified acute physiology 3 (SAPS3) score of admission date (t= -2.85, p= .006), Glasgow coma scale (GCS) of CPE acquisition date (t= 2.38, p= .020), artery catheter at CPE acquisition date (χ2 = 4.58, p= .032), vasoconstrictor agents use at CPE acquisition date (χ2 = 6.81, p= .009), platelet at CPE acquisition date (t= 2.27, p= .025), lymphocyte at CPE acquisition date (t= 2.01, p= .048), calcium at CPE acquisition date (t= 2.68, p= .009), albumin at CPE acquisition date (t= 2.29,p= .025), and creatinine at CPE acquisition date (t= 2.24, p= .028). Multivariate Cox proportional hazard model showed that GCS at CPE acquisition date (HR= 1.14, 95% CI= 1.05-1.22), lymphocyte at CPE acquisition date (HR= 1.05, 95% CI= 1.00-1.10), and creatinine at CPE acquisition date (HR= 1.25, 95% CI= 1.04-1.49) were independent survival factors among medical intensive care unit patients with CPE. @*Conclusion@#Based on the study results, it is necessary to develop nursing interventions that can aid in the management of patients with CPE and identify their effects.

ABSTRACT

To assess the academic performance, communication skills,and psychosocial development of prelingual deaf children with cochlear implants (CIs) attendingmainstream schools, and to evaluate the impact of auditory speech perception on theirclassroom performance. Subjects and Methods: As participant, 67 children with CI attendingmainstream schools were included. A survey was conducted using a structured questionnaireon academic performance in the native language, second language, mathematics, socialstudies, science, art, communication skills, self-esteem, and social relations. Additionally,auditory and speech performances on the last follow-up were reviewed retrospectively. Results:Most implanted children attending mainstream school appeared to have positive selfesteemand confidence, and had little difficulty in conversing in a quiet classroom. Also, halfof the implanted children (38/67) scored above average in general academic achievement.However, academic achievement in the second language (English), social studies, and sciencewere usually poorer than general academic achievement. Furthermore, half of the implantedchildren had difficulty in understanding the class content (30/67) or conversing withpeers in a noisy classroom (32/67). These difficulties were significantly associated with poorspeech perception. Conclusions: Improving the listening environment for implanted childrenattending mainstream schools is necessary.

ABSTRACT

This study aimed to compare functional hearing with the use ofa personal sound amplification product (PSAP) or a basic hearing aid (HA) among sensorineuralhearing impaired listeners. Subjects and Methods: Nineteen participants with mild-to-moderatesensorineural hearing loss (SNHL) (26-55 dB HL; pure-tone average, 0.5-4 kHz) wereprospectively included. No participants had prior experience with HAs or PSAPs. Audiograms,speech intelligibility in both quiet and noisy environments, speech quality, and preference wereassessed in three different listening conditions: unaided, with the HA, and with the PSAP. Results:The use of PSAP was associated with significant improvement in pure-tone thresholds at 1, 2,and 4 kHz compared to the unaided condition (all p<0.01). In the quiet environment, speechintelligibility was significantly improved after wearing a PSAP compared to the unaided condition(p<0.001), and this improvement was better than the result obtained with the HA. The PSAPalso demonstrated similar improvement in the most comfortable levels compared to those obtainedwith the HA (p<0.05). However, there was no significant improvement of speech intelligibilityin a noisy environment when wearing the PSAP (p=0.160). There was no significant differencein the reported speech quality produced by either device or in participant preference for thePSAP or HA. Conclusions: The current result suggests that PSAPs provide considerable benefitsto speech intelligibility in a quiet environment and can be a good alternative to compensatefor mild-to-moderate SNHL.

ABSTRACT

Background and Objectives@#One of the most common surgical procedures in children is adenoidectomy, but the causes of adenoid hypertrophy are not fully understood. Some studies have found that allergies can be a risk factor for adenoid hypertrophy, asthma being one of these allergic diseases. This study aimed to investigate the relationship between adenoid size and asthma in a group of children.Subjects and Method This study reviewed a total of 2063 pediatric patients with or without atopy and asthma who visited the Otorhinolaryngology and Pediatric unit at a tertiary medical center from January 2011 to June 2016. We classified these patients into 4 groups according to the presence of asthma or atopy and randomly selected 100 patients from each group (to a total of 400 pts): group 1 (asthma-, atopy-); group 2 (asthma-, atopy+); group 3 (asthma+, atopy-) and group 4 (asthma+, atopy+). The presence of allergic sensitization (atopy) was evaluated by CAP test and total IgE. Asthma was diagnosed according to the diagnosis criteria in the Korean guideline for asthma. Adenoid size was evaluated with the adenoidal-nasopharyngeal ratio (A/N ratio) by the adenoid view. @*Results@#The four groups did not differ from each other significantly in age or sex. There was a negative correlation between adenoid size and atopic and asthmatic condition. Group 1 had a significantly larger A/N ratio than the other groups (group 1=0.534±0.138; group 2=0.469± 0.140; group 3=0.476±0.135; group 4=0.482±0.128, p<0.05). However, group 4 showed nearly identical results to groups 2 and 3, despite the combination of asthma and atopy in group 4. @*Conclusion@#Large adenoids were negatively associated with atopy and asthma. This finding may be explained by a decrease in adenoid stimulation by nasal obstruction and a difference in the immune system, including allergic immune reactions. Further studies are needed.

ABSTRACT

BACKGROUND AND OBJECTIVES@#To analyze the difference in audiologic-vestibular and clinical characteristics between acute cochlea-vestibulopathy (ACV) and idiopathic sudden sensorineural hearing loss (ISSNHL).SUBJECTS AND METHOD: We retrospectively analyzed the clinical characteristics of 91 patients diagnosed as sudden hearing loss (ACV; n=20, ISSNHL; n=71). Patients with vestibular hypofunction were categorized as ACV and all others as ISSNHL. Demographics and clinical findings were compared. Audiologic features such as degree of hearing loss, type of audiometric configuration and hearing improvements were analyzed. In addition, vestibular function test results and hearing recovery were further analyzed among ACV group.@*RESULTS@#Demographics and other clinical findings were not much different between groups. There was a significant difference with respect to audiologic features between the ACV group and ISSNHL group: the initial hearing threshold of the ACV group was higher than that of the ISSNHL group, and their treatment onset was also shorter. There was also a significant difference in the hearing outcome showing very low rate of complete recovery in ACV group. The final hearing threshold of the ACV group was higher than that of the ISSNHL group. Dizziness was the only significant variable in the multiple regression analysis. In the ACV group, the cervical vestibular evoked myogenic potential inter-aural amplitude difference (cVEMP IAD) ratio showed a correlation to the hearing recovery in some frequencies; patients with no cVEMP response showed poor outcome compared to those with cVEMP waveform.@*CONCLUSION@#The ACV group shows a poor prognosis just as in the case of sudden hearing loss defined in the traditional sense of vertigo. The IAD value of the vestibular evoked myogenic potentials test will be helpful in assessing hearing improvement, especially when a high IAD value at the middle frequency is associated with a poor prognosis.

ABSTRACT

OBJECTIVES: Numerous studies have been reported on the effect of customized vestibular exercise (cVE), but only a few studies have been reported on the satisfaction of cVE. Therefore, this study aims to investigate the factors that affect the satisfaction of cVE. METHODS: A telephone survey was conducted on 37 patients who underwent cVE from January to November 2018. The questionnaire consisted of a total of 10 items, including subjective symptom, compliance and satisfaction of exercise, preferred methods of exercise, and appropriate costs. Based on the questionnaire of satisfaction, the clinical features, improvement of symptom, compliance, preferred methods of exercise were compared between satisfactory and unsatisfactory groups. RESULTS: Of the 20 patients who responded to the telephone survey (response rate 57%), 10 patients were included in the satisfactory group and the remaining 10 were included in the unsatisfactory group. There were no significant differences between the 2 groups in age, sex, severity of subjective symptom before cVE, preferred methods of exercise. However, patients in the unsatisfactory group were significantly more likely to have chronic vestibulopathy and abnormal findings in dynamic posturography test than those in the satisfactory group. Subjective dizziness after cVE was significantly decreased in the satisfactory group, but there was no significant difference in the unsatisfactory group. These patients in the unsatisfactory group still had dizziness, but tended not to continue to exercise. CONCLUSIONS: The satisfaction of cVE was significantly lower in patients with chronic vestibulopathy, postural instability, less improvement of dizziness, and poor compliance.

In the ACV group, the cervical vestibular evoked myogenic potential inter-aural amplitude difference (cVEMP IAD) ratio showed a correlation to the hearing recovery in some frequencies; patients with no cVEMP response showed poor outcome compared to those with cVEMP waveform. CONCLUSION: The ACV group shows a poor prognosis just as in the case of sudden hearing loss defined in the traditional sense of vertigo. The IAD value of the vestibular evoked myogenic potentials test will be helpful in assessing hearing improvement, especially when a high IAD value at the middle frequency is associated with a poor prognosis.
