ABSTRACT

Objectives@#. Balloon Eustachian tuboplasty (BET) is a novel treatment method for Eustachian tube dilatory dysfunction (ETD). However, surgeons cannot identify the insertion depth of the catheter during BET, resulting in potential risks such as internal carotid artery (ICA) injury. Therefore, we developed an image-guided navigation balloon catheter to identify the insertion depth of the catheter and to establish awareness of the proximity of the ICA. This study aimed to evaluate the technical feasibility of this image-guided navigation balloon catheter system in patients with ETD. @*Methods@#. Twenty-nine patients (38 ears; nine bilateral; 21 right ears, and 17 left ears) diagnosed with ETD were assessed. All patients who showed no improvement despite medical therapy with topical steroids, anti-reflux medication, and the Valsalva maneuver for a minimum of 6 weeks received image-guided navigation-assisted BET. The 7-item Eustachian Tube Dysfunction Questionnaire (ETDQ-7) score and Valsalva maneuver were used to evaluate patients’ symptoms preoperatively and at the postoperative follow-up. @*Results@#. Image-guided navigation-assisted BET was safely performed in all patients. The mean total ETDQ-7 score was 25.4±7.1 preoperatively, 17.5±6.2 at 1 month, and 15.2±7.0 at 6 months (P<0.001). In total, a Valsalva maneuver was possible for 28 of 38 ears (73.7%) at the time of the patient’s final visit at 6 months post-procedure. @*Conclusion@#. Image-guided navigation balloon catheters are a potentially valuable tool in patients with ETD. Their use is also technically feasible and safe when performing BET to treat ETD.

ABSTRACT

OBJECTIVES: To investigate the effect of surgical treatment with eustachian tube (ET) catheter insertion in patients with acquired cholesteatoma associated with patulous eustachian tube (PET) and habitual sniffing. METHODS: Nine ears of nine patients (two men and seven women; age, 20 to 65 years; average, 37.9±12.0 years) of acquired cholesteatoma associated with PET and habitual sniffing who underwent cholesteatoma surgery with simultaneous additional ET catheter insertion were examined in this study. Successful treatment was defined as stoppage of sniffing, a relief of a PET handicap inventory-10 (PHI-10), an improvement of autophony grade and no cholesteatoma recurrence. RESULTS: ET catheter insertion was performed in all ears. Follow-up duration ranged from 16 to 37 months (average, 25.4 months). Cases consisted of nine pars flaccida type (100%). All patients obtained relief from aural symptoms and stopped sniffing. Postoperative PHI-10 scores were significantly lower than preoperative scores (P<0.001). During an average follow-up of 25.4 months, no cholesteatoma recurrence has occurred to date. One patient developed otitis media with effusion (OME) post-catheterization; OME resolved spontaneously without treatment. Four patients had a consecutive ET catheter insertion on the other side to resolve PET-related aural symptoms. CONCLUSION: In case of acquired cholesteatoma with PET and habitual sniffing, ET catheter insertion performed simultaneously with cholesteatoma surgery could help reduce aural symptoms and stop sniffing. Moreover, the procedure might help in preventing cholesteatoma recurrence.

ABSTRACT

BACKGROUND: Early detection of tuberculosis (TB) is challenging in resource-poor settings because of limited accessibility to molecular diagnostics. The aim of this study was to evaluate the performance of the loop-mediated isothermal amplification kit (TB-LAMP) for TB diagnosis compared with conventional and molecular tests. METHODS: A total of 290 consecutive sputum samples were collected from May till September, 2015. All samples were processed using the N-Acetyl-L-cysteine (NALC) NaOH method and tested by smear microscopy, solid and liquid culture, real-time PCR, and TB-LAMP. RESULTS: The sensitivity of TB-LAMP for smear-positive and smear-negative samples with culture positivity was 92.0% and 58.8%, respectively. TB-LAMP was positive in 14.9% of TB culture-negative samples; however, all those samples were also positive by real-time PCR. In addition, none of the samples positive for nontuberculous mycobacteria by culture were positive by TB-LAMP. The overall agreement between TB-LAMP and real-time PCR was good; however, the concordance rate was significantly lower for real-time PCR positive samples with Ct values of 30–35. CONCLUSIONS: TB-LAMP could replace smear microscopy and increase TB diagnostic capacity when Xpert MTB/RIF is not feasible because of poor infrastructure.

ABSTRACT

BACKGROUND AND OBJECTIVES: The cause of idiopathic sudden sensorineural hearing loss (ISSNHL) is still unclear, but recently, chronic inflammation and thrombosis have received attention. The neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) are some of the markers that show the state of inflammation and ischemia, which are measured routinely in the complete blood cell count (CBC) test. The aim of this study were to investigate the relevance of NLR and PLR with ISSNHL. SUBJECTS AND METHOD: Enrolled in our retrospective analysis were 103 patients diagnosed with ISSNHL. Blood samples were taken from the patients and hearing assessments were performed. NLR and PLR were calculated using the CBC results. Then the patients were divided into 4 groups using Sigel's criteria according to their response to the treatment, which were again classified two groups, the “recovered” and “unrecovered” group. RESULTS: NLR, PLR, and neutrophil values of the unrecovered group were significantly higher than the recovered group (p=0.002, p=0.009, and p=0.038, respectively). On the other hand, lymphocyte values were significantly higher in the recovered group (p=0.007). After adjustment in a multivariate logistic regression analysis, NLR was associated with the recovery of ISSNHL (Odds ratio=1.290, p=0.042). In addition, NLR and PLR values were also significantly different between the groups classified by the Sigel's criteria (p=0.009 and p=0.029, respectively). CONCLUSION: PLR values may be useful in predicting hearing recovery after treatment in patients with ISSNH. It is also expected to be a potential marker for predicting the prognosis and determining further treatment options.

ABSTRACT

OBJECTIVE: To demonstrate the utility of Scale for the Assessment and Rating of Ataxia (SARA) for evaluation of posterior circulation-related features in patients with mild stroke. METHODS: Forty-five subjects, diagnosed with acute infarction in the cerebellum, basis pontis, thalamus, corona radiata, posterior limb of internal capsule, and their National Institutes of Health Stroke Scale (NIHSS) scores ≤5 were enrolled. SARA scores were graded by the cut-off value of severity in dependency of activities of daily living (ADL). SARA, Berg Balance Scale (BBS), Timed Up-and-Go (TUG), and Trunk Control Test (TCT) were correlated in regression analysis with the modified Rankin Scale (mRS) at discharge. Correlation between SARA and other tools was analyzed. Patients were divided based on mRS at admission (group A, mRS 0–2; group B, mRS 3–5). Scores between the two groups were compared. RESULTS: Among the subjects, 48.9% (22/45) scored above 5.5 on SARA, and even 11.1% (5/45) scored higher than 14.25, which is the cut-off value of ‘severe dependency’ in ADL. SARA showed significant value for prediction of mRS at discharge. SARA was correlated with BBS (r=-0.946, p < 0.001), TUG (r=-0.584, p < 0.001), and TCT (r=-0.799, p < 0.001). The SARA, BBS, TUG, and TCT scores between were lower in group B than in group A patients. SARA as well as BBS, TUG, and TCT reflect the functional severity of all patients. CONCLUSION: SARA is a complementary tool for evaluation of the severity of ataxia in mild stroke patients with features of posterior circulation.

ABSTRACT

PURPOSE: To evaluate the clinical differences between patients with central serous chorioretinopathy (CSC) developed after steroid use and CSC patients without a history of steroid use for short-term periods. METHODS: We retrospectively analyzed the medical records of 47 patients (55 eyes) diagnosed with CSC from January 2011 to August 2017 by categorizing Group 1 (32 patients, 36 eyes) without a history of steroid use and Group 2 (15 patients, 19 eyes) with a history of steroid use within 6 months. We evaluated the differences in best-corrected visual acuity (BCVA), subretinal fluid (SRF) height, subfoveal choroidal thickness (SFCT), and Haller's layer thickness in the two groups. We also analyzed the changes in the BCVA, SRF height, SFCT, and Haller’s layer thickness in each group for 1 month and compared them depending on the treatment. RESULTS: There were no significant differences between the two groups with regard to age, sex, BCVA, bilaterality, number of leakage points, and Haller's layer thickness. Group 2 showed significantly increased SRF height and SFCT than Group 1 (p = 0.002, p = 0.005, respectively). In Group 1, the level of SRF and SFCT were significantly more decreased after 1 month (p = 0.001, 0.015, respectively) in patients with treatment than in those without treatment. In Group 2, the height of the SRF and SFCT were significantly more decreased after 1 month (p = 0.005, 0.002, respectively) in untreated patients compared to treated patients. CONCLUSIONS: CSC patients with a prior history of steroid use have higher serous detachment and a thicker SFCT than those without prior history of steroid use. Therefore, termination of steroid treatment may reduce the SFCT and SRF in steroid-treated CSC patients.

ABSTRACT

Posterior semicircular canal dehiscence represents a third-window lesion manifesting as hearing loss with vestibular dysfunction. Computed tomography findings of a dehiscent posterior canal can be verified with increased vestibular evoked myogenic potential responses as in other third-window lesions. The jugular bulb is the bulbiform connection between the sigmoid sinus and the internal jugular vein at the skull base. High jugular bulb can erode into inner ear structures. According to the literature review, there has been no case report about posterior semicircular canal dehiscence caused by high jugular bulb in Asia. Therefore, the authors report a case with a review of literature.

ABSTRACT

OBJECTIVE: The purpose of this meta-analysis was to determine the applicability of web-based treatment programs for individuals with depression and quality of life impairments. METHODS: We conducted database and manual searches using imprecise search-term strategy and inclusion criteria. Research published from 2005 to December 2015 was included in this study. Upon review, a total of 12 published papers on web-based intervention for individuals with depression were assessed eligible for this meta-analysis. Effect sizes were estimated for depression and quality of life. RESULTS: The mean effect size of web-based treatment on depressive symptoms was 0.72. However, unlike the result showing medium to large effect size, the analysis on the quality of life did not yield adequate effects of web-based interventions. CONCLUSION: Our results suggest robust benefits of employing web-based treatments for depressive symptoms. However, the adequacy of these relatively new intervention tools for individuals who suffer severe impairments of quality of life was found insufficient. The current study demonstrates the need to further develop web-based intervention techniques to improve overall functioning, as well as the clinical symptoms of patients with mental disorders.

ABSTRACT

Benign acute childhood myositis (BACM) is a rare transient condition that occurs in children during the early convalescent phase of a viral upper respiratory infection. BACM is self-limiting and characterized by sudden-onset bilateral calf pain that leads to difficulty in walking. We report a case of a 5-year-old boy with BACM who presented with acute-onset bilateral calf pain after a resolved episode of viral pharyngitis and subsequently refused to walk. With conservative treatment, the patient recovered completely after approximately 1 week. Although perplexing and challenging for clinicians unfamiliar with BACM, awareness of this rare clinical condition is essential to preventing unnecessary investigations and reassuring the patient and parents of its excellent prognosis.

ABSTRACT

BACKGROUND: An increase in the obese adolescent population is being recognized as a serious medical and social problem. The present study aimed to examine the association between neighborhood socioeconomic status (SES) and obesity in Korean adolescents based on total available resources and local social inequality models. METHODS: The present study used data from the 2013 Korea Youth Risk Behavior Web-based Survey in analyzing 72,438 Korean adolescents aged 12-18. The analysis investigated obesity odds ratio (OR) according to neighborhood SES adjusted for age and individual SES indices, which included family affluence scale (FAS), education level of parents, cohabitation with parents, and weekly allowance. Obesity OR was investigated according to neighborhood SES by FAS, and according to FAS by neighborhood SES. RESULTS: After adjusting for age and individual SES variables, there was no significant association between neighborhood SES and adolescent obesity for either boys or girls. However, girls in the high FAS group showed a pattern of lower neighborhood SES being associated with a significant increase in risk of obesity; in the high neighborhood SES group, boys showed a pattern of higher FAS being associated with a significant increase in risk of obesity, whereas girls show a pattern of decrease. CONCLUSION: Although limited, the present study demonstrated that some girl groups exhibited a pattern of lower neighborhood SES being associated with an increase in risk of obesity, as well as a gender-based difference in risk of obesity by individual SES. Therefore, measures to prevent adolescent obesity should be established with consideration for differences in risk according to individual and neighborhood SES.

ABSTRACT

Myelodysplastic syndrome (MDS) is a bone marrow failure syndrome characterized by cytopenia that results in high risks of infection and bleeding. However, there are few reports of cerebral infarction in MDS. We reported a 72-year-old female with MDS who developed acute cerebral infarction. Clinical history of the patient revealed no definite risk factors for stroke except diabetes mellitus and dyslipidemia that was well controlled. This case represented the rare occurrence of arterial thrombosis causing acute cerebral infarction in MDS, which may be due to complex chromosomal abnormality and inflammatory processes.

ABSTRACT

PURPOSE: To report a case of lipemia retinalis in a patient with diabetes. CASE SUMMARY: A 27-year-old female with type 2 diabetes visited our clinic with visual disturbance in her left eye while being followed up from a pars plana vitrectomy in her right eye for proliferative diabetic retinopathy. On fundus examination of both eyes, the retinal vessels were creamy white and the retinal veins were undistinguishable from the retinal arteries. The serum triglyceride level was 2,676 mg/dL. The patient was asymptomatic except for visual impairment due to vitreous hemorrhage in her left eye. The patient was diagnosed with lipemia retinalis and chylomicronemia syndrome. After controlling the triglyceride level, funduscopic findings in the both eyes were improved. However, the visual acuity in her right eye remained unchanged. CONCLUSIONS: Lipemia retinalis can be a sign of a systemic condition although it may not affect visual acuity. Fundus examination may be a useful tool in the early diagnosis of hyperlipidemia.

ABSTRACT

BACKGROUND/AIMS: Hood cap-assisted chromocolonoscopy using indigocarmine is expected to improve the detection rate of colorectal polyps, especially adenomatous polyps. Therefore, aim of the present study was to evaluate the usefulness of hood cap-assisted chromocolonoscopy in routine colonoscopic examinations. METHODS: From January, 2013 through March, 2013, a total of 86 patients were enrolled (M:F=33:53, mean age=60 years). For each patient, hood cap-assisted colonoscopic examination was performed, followed by hood cap-assisted chromocolonoscopy using 0.2% indigocarmine from the cecum to the hepatic flexure. Total numbers and characteristics of polyps were compared before and after indigo carmine dye spraying. RESULTS: Prior to dye spraying, 48 polyps were found in 37 patients, and after dye spraying, 53 additional polyps were found in 34 patients. Of these undetected polyps, 45 (85%) were small sized polyps (< or =0.5 cm). Histologically, 19 (36%) were adenomatous polyps, and of these, 15 (28%) were tubular adenomas and 4 (8%) were serrated adenomas. As for the polyp detection rate, there was no difference between the expert and the non-expert groups. CONCLUSION: Hood cap-assisted chromocolonoscopic examination using indigocarmine was helpful in detecting cecum and ascending colon polyps, especially small sized polyps (<0.5 cm) and neoplastic polyps.

ABSTRACT

PURPOSE: To investigate the risk factors and the factors affecting surgical and visual outcomes of rhegmatogenous retinal detachment in patients under 40 years of age. METHODS: This retrospective study included 88 patients (96 eyes) diagnosed with rhegmatogenous retinal detachment that were followed up for more than 3 months postoperatively. Patients were categorized into 3 groups according to age. The etiologic risk factors and the primary anatomical and functional success rates were analyzed. Preoperative factors that could affect postoperative visual acuity and primary anatomical outcome, such as subretinal strands and proliferative vitreoretinopathy (grade C or worse), were analyzed. RESULTS: Myopia more severe than -4.0 diopters was the most common predisposing factor in all 3 groups. Anatomical success rates and functional success rates were not significantly different among the groups. Prevalence of macular detachment and proliferative vitreoretinopathy were highest in group 1. The presence of subretinal strands was highest in group 2 and proliferative vitreoretinopathy was highest in group 1. Patients with preoperative subretinal strands showed a lower primary anatomical success rate in group 1 and poor postoperative visual acuity in groups 1 and 2. Patients with proliferative vitreoretinopathy had poor postoperative visual acuity however there was no significant difference in primary anatomical success rate among the groups. CONCLUSIONS: Proliferative vitreoretinopathy did not affect the anatomical success rate but did affect visual outcome in rhegmatogenous retinal detachment in patients under age 40. Subretinal strands contributed to a lower anatomical success rate and poorer visual outcome in such patients that were under age 18.

ABSTRACT

BACKGROUND/AIMS: A few studies showed that hood-cap assisted colonoscopy (CAC) had improved cecal intubation rate and cecal intubation time but did not help in finding colon polyps in comparison with conventional colonoscopy (CC). However, other studies have shown different results. Therefore, we investigated the efficacy of CAC for the cecal intubation time and polyp detection rate. METHODS: Patients for colonoscopy in Busan St. Mary's Medical Center were enrolled to this randomized controlled trial between July 2010 and September 2010. The evaluated outcomes were polyp detection rate, adenoma detection rate, and cecal intubation time in all patients, in difficult cases (history of previous abdominal or pelvic surgery, obesity, old age), and in the expert and non-expert groups. RESULTS: A total of 260 patients enrolled in this study were randomly allocated to the CAC group (n=130), or CC group (n=130). The overall cecal intubation time was shorter in the CAC group (5.7+/-3.4 min vs. 7.8+/-5.7 min, P<0.001). The polyp detection rate was higher in the CAC group (58.4% vs. 43%, P=0.008). The cecal intubation time in the expert and non-expert groups were shorter in the CAC group (expert: 4.1+/-2.2 min vs. 5.5+/-2.0 min, P=0.001; non-expert: 6.7+/-3.7 min vs. 9.4+/-5.9 min, P=0.001). CONCLUSIONS: The use of CAC improved the detection rate of colon polyps and shortened the cecal intubation time for both the expert and non-expert groups.

ABSTRACT

Large anterior cervical osteophytes occur in the process of degeneration of the cervical spine or diffuse idiopathic skeletal hyperostosis. Extensive cervical spine osteophytes can produce dysphagia and laryngeal symptoms, including hoarseness, dysphonia, dyspnea and etc. But spontaneous bleeding is rare manifestation. Dysphagia and airway obstruction can be treated by surgical excision of osteophytes if conservative support fails. We present a case of a 76-year-old patient with massive bleeding from posterior hypopharyngeal wall and progressive dysphagia. When angiographic embolization and endoscopic bleeding control failed, the patient died of uncontrolled hemorrhage, and the subsequent disseminated intravascular coagulation and multi-organ failure.

ABSTRACT

BACKGROUND AND OBJECTIVES: The purpose of this study was to compare the surgical outcomes of uvulopalatal flap (UPF) and palatal muscle resection (PMR) techniques in the treatment of obstructive sleep apnea (OSA). SUBJECTS AND METHOD: Forty-three consecutive patients (40 men and 3 women) with OSA were included. Only patients with Fujita type I obstruction were enrolled in this study. Patients with macroglossia or retrognathia were excluded from the study. Twenty patients underwent a UPF and twenty-three patients underwent a PMR. In both groups, nasal surgery was performed if necessary. Questionnaires based on Visual Analogue Scale (VAS) about snoring, apnea, morning headache, tiredness, daytime sleepiness and Epworth Sleepiness Scale (ESS) were analyzed before and after each surgical treatment. Preoperative and postoperative polysomnography (PSG) were completed by every patient. RESULTS: In UPF group, every aspect of VAS except morning headache was significantly improved after surgery. In PMR group, every aspect of VAS and ESS were significantly improved after surgery. Comparing the surgical outcomes between two groups, every VAS and ESS showed much better result in PMR than UPF group. In both UPF and PMR group, the mean apnea-hypopnea index decreased significantly after surgery. However, there's no significant difference between two groups in the PSG findings. CONCLUSION: PMR could be a better surgical technique than UPF with respect to subjective outcome although both UPF and PMR are effective surgical techniques for the treatment of OSA with Fujita type I obstruction.

ABSTRACT

OBJECTIVE: To provide the off-loading knee brace was designed relief for the pain associated with osteoarthritis by reduce loads on the degenerative compartment of the knee. This study examined the effects of the off-loading knee brace on activation of femoral muscles during squatting, slow and fast walking exercise in healthy young individuals. METHOD: Ten healthy male subjects without a history of knee pain were recruited. Each subject was asked to do squatting, slow and fast walking exercises with a brace secured to the dominant leg. The same exercises were repeated without the brace. Surface electromyographic (sEMG) data was collected from the vastus medialis oblique (VMO), vastus lateralis (VL) and biceps femoris (BF) muscles from the dominant side of the leg. All dynamic root mean squre (RMS) values of sEMG were standardized to static RMS values of the maximal isometric contraction and expressed as a percentage of maximal activity. RESULTS: We found that VMO activity was significantly decreased with application of the off-loading knee brace during squatting and fast walking exercise. However there were no significant differences in VMO activity with application of the off-loading knee brace during slow walking exercise. CONCLUSION: These results suggest that the external moment of the brace which effectively stabilized the patella in the movement in which the knee joints become relatively unstable. The brace could be useful in the short term, but for long-term use, weakening of the VMO is predicted. Therefore the program of selective muscular strength strengthening for the VMO should be emphasized.
