With advances in implant technology, total ankle arthroplasty (TAA) has become an increasingly popular alternative to arthrodesis for the management of end-stage ankle arthritis. However, reports in the literature do not focus on the imaging features of TAA. Through a literature review, we demonstrate basic design features of the current ankle arthroplasty system, and the normal and abnormal postoperative imaging features associated with such devices. Pre- and postoperative evaluations of ankle arthroplasty mainly include radiography; in addition, computed tomography and magnetic resonance imaging provide further characterization of imaging abnormalities. Familiarization with multimodal imaging features of frequent procedural complications at various postoperative intervals is important in radiological practice.

Background and Objectives: The pathogenesis of idiopathic sudden sensorineural hearing loss (ISSNHL), an otologic emergency disease, remains unclear. Several studies have attempted to illustrate the association between cytokines and ISSNHL. The purpose of this study was to evaluate the prognostic significance of various cytokines in patients with ISSNHL. Subjects and Method In this case-control study, a total of 55 patients with ISSNHL underwent treatment with oral prednisolone for 2 weeks. Serum cytokine levels, including interleukins (ILs) (IL-1a, IL-1b, IL-2, IL-4, IL-6, IL-7, IL-8, IL-10, IL-12), and tumor necrosis factors (TNF-α and TNF-β), were measured using human cytokine panels at first visit. Patient characteristics such as age, gender, the status of hypertension, diabetes mellitus, vertigo, time from onset to visit, and initial hearing levels were also evaluated. Results: Serum levels of cytokines were correlated with the prognosis of ISSNHL patients. IL-4 ≥0.225 (pg/mL) and TNF-α ≥5.155 (pg/mL) were significantly associated with poor therapeutic outcomes (OR=44.317, p=0.015 and OR=269.465, p=0.006, respectively). In addition, age and initial hearing levels were also significant prognostic factors. Conclusion Patients’ age, initial hearing levels, and serum levels of IL-4 and TNF-α prior to treatment are associated with hearing recovery and can be used as prognostic factors for patients with ISSNHL.

Cognitive behavioral therapy, first introduced by Beck in the 1950s to treat depression by integrating cognitive and behavioral therapies, is now an established psychotherapy technique used to treat insomnia, chronic pain, and anxiety. Currently, cognitive behavioral therapy is widely used to treat tinnitus in European countries, and the efficacy and safety of the treatment have been proven through randomized clinical trials and meta-analyses. Although interest in cognitive behavioral therapy for tinnitus is increasing in Korea, there are limited reports. Because many studies so far have targeted patients in Western countries, it is difficult to apply the same to domestic patients due to cultural and linguistic differences, the absence of standardized guidelines, and limitations in clinic hours. We experienced various cases in which tinnitus was effectively treated simultaneously with pharmacotherapy and cognitive behavioral therapy, so here we report an introduction to the program along with a literature review. Cognitive behavioral therapy was performed as a 4-week program in our hospital, and progress was evaluated through Visual Analogue Scales (VAS) and tinnitus handicap inventory (THI). After each weekly 20-minute individual counseling session, a take-home writing task was given to the patient. The main goal was to guide the patient to discover and correct automatic thoughts related to their tinnitus symptoms. This paper aimed to introduce a specific scheme on how to perform cognitive behavioral therapy for domestic tinnitus patients.

BACKGROUND AND OBJECTIVES: Pediatric vocal health problems are relatively common. However, it is not yet well studied whether uniform diagnosis and treatment is done properly in South Korea. The purpose of this study was to investigate the methods that the Korean speech therapists use to diagnose and treat pediatric voice problem. MATERIALS AND METHOD: An anonymous online questionnaire was administered to 32 speech language therapists registered at the Korean laryngeal speech linguistics society detailing demographics, employment institution, general management of pediatric patients with vocal problem including assessment and treatment procedures. RESULTS: Current practice patterns were analyzed on 32 speech language therapists providing services in South Korea mostly working at tertiary university hospital. One third of pediatric patients were assessed without proceeding to treatment. One fifth of patients were treated without assessment. Perceptual assessment was the main pre-treatment assessment methods used. Treatment was done in the following order : Voice rest, SOVT, yawn-sigh and resonant voice. Post-treatment evaluation was used in the following order : Instrumental assessment, clinical judgment, and recording comparison. CONCLUSION: Speech language therapists practice in South Korea mostly follows the ASHA practice guidelines. However, there are still great amount of cases in which only the evaluation was done without appropriate treatment. Further research is needed to make SPLs more systematic and efficient for evaluating and treating pediatric vocal patients.
