Radiofrequency ablation (RFA) is a minimally invasive treatment modality used as an alternative to surgery in patients with benign thyroid nodules, recurrent thyroid cancers (RTCs), and primary thyroid microcarcinomas. The Korean Society of Thyroid Radiology (KSThR) initially developed recommendations for the optimal use of RFA for thyroid tumors in 2009 and revised them in 2012 and 2017. As new meaningful evidence has accumulated since 2017 and in response to a growing global interest in the use of RFA for treating malignant thyroid lesions, the task force committee members of the KSThR decided to update the guidelines on the use of RFA for the management of RTCs based on a comprehensive analysis of current literature and expert consensus.

Objective: Phototherapy is a widely used treatment for neonatal hyperbilirubinemia, but the potential risks in early preterm infants are not well known. So it seems to be necessary to find out which parameters should be carefully observed during phototherapy. In this study, we analyzed blood pressure (BP), heart rate (HR), and body temperature (BT) in preterm infants under 32 weeks of gestational age before and after phototherapy. Methods: In this study, we analyzed the medical records of 103 early preterm infants with gestational age <32 weeks and birth weight >1,000 g admitted to the neonatal intensive care unit, treated with and without phototherapy, at Wonju Severance Christian Hospital, a tertiary center in Korea. Changes in BP, HR, and BT were analyzed before and after treatment. Results: A total of 91 patients taking phototherapy and 12 control subjects were enrolled. In the phototherapy group (PT group), PT was started on the second day after birth and lasted for 74 hours.In between-group analysis, HR was higher in the PT group after starting phototherapy (at 48 hours;median of differences 8 bpm, P=0.005, at 56 hours; median of differences 9 bpm, P=0.001), while there was no significant difference in BP. The rate of BP increase was lowered and HR was increased after phototherapy, in the PT group analysis. Conclusion After starting phototherapy in preterm infants less than 32 weeks of gestational age, the increasing trend in BP was ceased and the HR was increased.

Purpose: The purpose of this study is to conduct job analysis of nurses at dementia care centers and to identify the importance, frequency, and difficulty of each duty and task. Methods: Through Developing a Curriculum (DACUM) Committee workshop, the committee members developed a job analysis tool using DACUM, and the nurses working at dementia care centers evaluated the importance, frequency, and difficulty of each duty and task. Results: The jobs of the nurses were derived from 10 duties and 66 tasks, and each duty consisted of 3 to 10 tasks. The important duties were ‘public guardianship project for dementia’ and ‘dementia diagnosis screening,’ the most frequent duties were ‘consultation and registration management,’ and ‘dementia diagnosis screening,’ and the most difficult duties were ‘public guardianship project for dementia’ and ‘project planning and evaluation.’ Based on these results, the core duties and tasks were derived, and the top priority duties were ‘consultation and registration management,’ ‘case management,’ and ‘support for families and carers of dementia patients’. Conclusion The most recent duties of nurses, who have the largest proportion of workers at dementia care centers, were identified, and the core duties that should be given priority in selecting the direction of education for job performance and professional improvement were presented. Based on the application method of education and training presented in this study, it is important to detail education and training that is appropriate for and applicable to each duty to support the professionalism of nurses at dementia care centers.

Purpose: The associated factors for hypertensive retinopathy (HTR) are rarely investigated. This study aimed to identify the associated factors for HTR using a systematic review. Methods: The review included cross-sectional, case-controlled, and cohort studies on HTR risk factors published in Korean and English with full texts available from PubMed, Embase, CINAHL, Web of Science, and Korean databases. Methodological quality was assessed using the Joanna Briggs Institute (JBI) checklist. Results: Eleven studies were finally selected, and three studies including patients with hypertension without diabetes mellitus, older age, male sex, alcohol consumption, the duration of hypertension, hyperglycemia, dyslipidemia, microalbuminuria, high creatinine levels, chronic kidney disease, and cardiovascular changes were identified as factors associated with HTR. Conversely, in the remaining eight studies, younger age, non-smoking status, and renal function indicators (albuminuria, high creatinine levels, chronic kidney disease, and uric acid) were identified as associated factors. Conclusions Regardless of the inclusion of patients with diabetes mellitus, impaired kidney functions were determined as significant factors associated with retinopathy in patients with HTR. However, considering a limited number of evidence and lack of evidence to confirm causality, we recommend further research on renal function and HTR.

The prevalence of postpartum depression (PPD) in Asia is reported to range from 13.53% to 22.31%. However, there remains a gap in the identification of PPD, particularly regarding cultural cutoff points. Therefore, the purpose of this scoping review was to determine the prevalence and associated factors of PPD in Eastern, South-eastern, Western, and Southern Asian countries and analyze the cutoff points of the Edinburgh Postnatal Depression Scale (EPDS) used across these countries. Following Arksey and O'Malley’s five-step scoping review framework, the population was defined as mothers, the concept as the EPDS, and the context as the Asian region. A literature search was conducted using PubMed, Embase, CINAHL, PsycINFO, and Web of Science. The data analysis focused on demographic characteristics, EPDS cutoffs and features, PPD prevalence, and its associated factors. Nineteen studies were selected. Most countries used translated versions of the EPDS with demonstrated reliability and validity. The cutoff scores varied, with most using scores of 10 or higher. The prevalence of PPD ranged from 5.1% to 78.7%. Key associated factors for PPD included cultural factors such as relationships with in-laws and preferences for the newborn’s sex. To improve the accuracy of PPD screening in Asia, the EPDS should be used consistently, and appropriate cutoff criteria must be established. In addition, prevention strategies and programs that reflect the cultural characteristics and social context of Asia need to be developed for the early detection and prevention of PPD.

Patients with ectodermal dysplasia often have atrophied alveolar bone and an inadequate maxillomandibular relationship owing to congenital edentulism.Accurate implant placement that can overcomes anatomical limitations and orthognathic surgery to improve the maxillomandibular relationship is necessary for creating implant-supported prosthesis for these patients. Implant placement and provisional prosthesis fabrication before orthognathic surgery can provide critical fixed reference points and ensure accuracy during orthognathic surgery.In our patient, a digital system was used to design a surgical guide that considered the predictable position of the definitive prosthesis, allowing the placement of implants to overcome anatomical limitations and the creation of fixed reference points via the delivery of a provisional prosthesis for effective orthognathic surgery. The lack of compensation during orthognathic surgery was considered in the definitive prosthesis. As a result, a prosthesis with a minimal anterior cantilever was fabricated. This study aimed to determine the appropriate sequence of multidisciplinary collaborations that would, result in the best functional and aesthetic outcomes.
