Background: There is a growing demand for extending dosing intervals of dupilumab injections in patients with atopic dermatitis (AD) due to treatment burden and side effects. However, studies on successful dose reduction in real-world settings are lacking. Objective: To assess the efficacy of a patient-centered dupilumab tapering regimen and to propose guidelines for target patients, appropriate intervals, and timing for tapering. Methods: This single-center retrospective study included moderate to severe adult AD patients who underwent at least 16 weeks of dupilumab treatment. Interval prolongation was considered in controlled patients assessed by Eczema Area and Severity Index (EASI) score and serum inflammatory markers after at least 40 weeks of treatment with a standard regimen. Logistic regression model with generalized estimating equations was used to compare repetitive measurements over time between the two groups. Results: A total of 52 patients were included with 11 patients extending intervals to 3–4 weeks without flare-ups. The mean duration of dupilumab treatment before tapering was 53.27 weeks. The tapering group exhibited significantly lower body mass index. All patients of the tapering group showed EASI scores under 4 and immunoglobulin E (IgE) levels under 1,000 IU/mL at week 40. EASI scores and IgE levels remained consistently low after dose reduction, with a mean follow-up time of 14.36 months. Conclusion Patients with extended dosing intervals demonstrated sustained effectiveness. Dose tapering might be a valuable option for non-obese patients with positive clinical response characterized by an EASI score under 4 and IgE levels under 1,000 at week 40.

Colorectal cancer is the third most common cancer in Korea and the third leading cause of death from cancer. Treatment outcomes for colon cancer are steadily improving due to national health screening programs with advances in diagnostic methods, surgical techniques, and therapeutic agents.. The Korea Colon Cancer Multidisciplinary (KCCM) Committee intends to provide professionals who treat colon cancer with the most up-to-date, evidence-based practice guidelines to improve outcomes and help them make decisions that reflect their patients’ values and preferences. These guidelines have been established by consensus reached by the KCCM Guideline Committee based on a systematic literature review and evidence synthesis and by considering the national health insurance system in real clinical practice settings. Each recommendation is presented with a recommendation strength and level of evidence based on the consensus of the committee.

In May 2023, the Committee of Clinical Practice Guidelines of the Korean Diabetes Association published the revised clinical practice guidelines for Korean adults with diabetes and prediabetes. We incorporated the latest clinical research findings through a comprehensive systematic literature review and applied them in a manner suitable for the Korean population. These guidelines are designed for all healthcare providers nationwide, including physicians, diabetes experts, and certified diabetes educators who manage patients with diabetes or individuals at risk of developing diabetes. Based on recent changes in international guidelines and the results of a Korean epidemiological study, the recommended age for diabetes screening has been lowered. In collaboration with the relevant Korean medical societies, recently revised guidelines for managing hypertension and dyslipidemia in patients with diabetes have been incorporated into this guideline. An abridgment containing practical information on patient education and systematic management in the clinic was published separately.

One of the common complications that can occur during coil embolization of cerebral aneurysms, is migration of coil lump alone. The removal of these migrated coils has been reported on a few occasions. On the other hand, rare complications would include the migration of the coil with subsequent stent dislocation. Currently, there is no standardized method to correct the complications of stent dislocation, and very few instances of this complication have been reported previously. In this report, we introduce a case of coil migration combined with stent dislocation. This occurred during coil embolization of an unruptured aneurysm of the distal, left internal carotid artery for a 52-year old woman. We retrieved both the damaged stent and migrated coil using another retrievable stent successfully with no more further complications. In the present report, we describe in detail how we corrected the complication successfully stent, and we discuss why this rescue maneuver is reasonable option for the complication mentioned above.

The treatment of pathological scars, such as keloids and hypertrophic scars, can be challenging for dermatologists. The first-line treatment is intralesional corticosteroid injection, especially when patients complain of pain or discomfort. Laser treatment can also be used in patients with keloids and hypertrophic scars. However, even after multiple sessions of intralesional corticosteroid injections and laser treatment, desirable outcomes may not be achieved, and recurrence is common. Recent studies on the efficacy of intralesional bleomycin injection (BLMILI) in treating keloids and hypertrophic scars have suggested that a significant improvement is observed after BLMILI. However, there is limited research on the effectiveness of BLMILI for patients who do not respond to other treatments, such as intralesional corticosteroid injection or laser treatment. Here, we report four cases of BLMILI in keloids and hypertrophic scars that were unresponsive to previous intralesional corticosteroid injection and/or laser treatment.

Background: Various treatments exist for addressing volume loss in atrophic scars. Although laser therapy has gained traction in treating atrophic scars, it is associated with side effects, such as post-inflammatory hyperpigmentation or erythema. Additionally, not all types of atrophic scars respond optimally to laser therapy, even after multiple sessions. Objective: This study aimed to evaluate the efficacy and safety of punch elevation for atrophic scars that yielded unsatisfactory outcomes after repeated laser treatment sessions. Methods: Seven patients with atrophic scars on their facial area underwent punch elevation, concurrently supplemented by fractional CO2 laser application to the scar margins. Improvement in volume restoration of atrophic scars was assessed via investigator evaluation and 3-dimensional (3D) image analysis. Results: After 1 month, median volume (interquartile range) of depression improved from 4.39 mm3 (2.23∼9.90 mm3 ) to 1.97 mm3 (1.46∼7.50 mm3 ), indicating a statistically significant difference post-punch elevation (p=0.018). No serious adverse events were reported during follow-up. Conclusion The efficacy of the punch elevation was objectively evaluated. Punch elevation is a safe and effective therapeutic avenue for atrophic scars that exhibit resistance to laser or alternative interventions.

Background: Personal socio-economic abilities are crucial as it affects health inequalities. These multidimensional inequalities across the regions have been structured and fixed. This study aimed to analyze health vulnerabilities by regional cluster and identify regional health disparities of self-rated health, using nationally representative cross-sectional data. Methods: This study used personal and regional data. Data from the Community Health Survey 2021 were analyzed. K-means cluster analysis was applied to 250 si-gun-gu using administrative regional data. The clusters were based on three areas: physical environment, health-related behaviors and biological factors, and the psychosocial environment through the conceptual framework for action on the social determinants of health. And binary logistic regression analyses were conducted to examine the differences in self-rated health status by the regional clusters, controlling human biology, environment, lifestyle, and healthcare organization factors. Results: The most vulnerable group was group 3, the moderate vulnerable group was group 1, and the least vulnerable group was group 2. The group 2 was more likely to have high self-rated health status than the moderate vulnerable group (odds ratio [OR], 1.023; p<0.001). And the group 3 showed low self-rated health status than the moderate vulnerable group (OR, 0.775; p<0.001). However, the moderate vulnerable group had significantly higher self-rated health status than the most vulnerable group (group 2:OR, 1.023; p<0.001; group 3: OR, 0.775; p<0.001). Conclusion These results demonstrate that community members’ health status is influenced by regional determinants of health and individual levels. And these contribute to understanding the importance of specific and differentiated interventions like locally tailored support programs considering both individual and regional health determinants.

Aggressive digital papillary adenoma (ADPA) is a rare tumor of the sweat glands. They usually present as solitary masses, with or without pain, and are most commonly observed in the fingers. A 19-year-old man presented with a solitary, protruding lesion on the right big toe that had enlarged 6 months previously. The biopsy specimen revealed a well-marginated mass with papillary projections and tubular structures. On foot magnetic resonance imaging, there was no invasion, and chest radiography showed no metastasis. Based on these findings, the tumor was diagnosed as ADPA, and wide excision was performed. Herein, we report a rare sweat gland tumor on the toe that was diagnosed as an ADPA.
