Symmetric drug-related intertriginous and flexural exanthema (SDRIFE) is a rare drug-induced skin reaction characterized by distinctive rashes. It presents as sharply demarcated erythema in “V” shape on the flexural areas such as the buttocks and the groin. Additionally, it can affect other flexural regions such as the axillae, popliteal fossae, and antecubital fossae. SDRIFE typically occurs within a few days following systemic drug exposure, without prior cutaneous sensitization. It is generally associated with a favorable prognosis with no systemic involvement. Consequently, treatment usually involves discontinuation of the offending drug and symptomatic management with antihistamines, with systemic corticosteroids rarely necessary. Herein, we report a case of severe SDRIFE that developed six weeks after denosumab administration and required long-term systemic corticosteroids.

Purpose: There is few evidence regarding the optimal salvage treatment options for loco-reginal recurrence of esophageal cancer. This study aimed to evaluate the clinical outcomes of salvage radiotherapy (RT) in patients with loco-regional recurrence (LRR) after surgery for esophageal cancer. Materials and Methods: We retrospectively reviewed 147 esophageal cancer patients who received salvage RT for loco-regional recurrence between 1996 and December 2019. A total dose of 60 Gy in 20 fractions was used for RT alone and 60-70 Gy in 30-35 fractions for concurrent chemoradiotherapy (CCRT). Results: The patients’ median age was 65 years (range, 41 to 86 years). The median disease-free interval was 13.5 months (1.0 to 97.4 months). After a median 18.8 months follow-up, the 2-year overall survival (OS) and progression-free survival (PFS) rates were 38.1% and 25.9%, respectively. The median OS and PFS were 18.8 and 8.4 months, respectively. The CCRT could not improve OS compared to RT (p=0.336), but there was a trend of better PFS in the CCRT group. Regarding toxicities, the rate of grade 3 or higher toxicity was 10.9% occurring in 16 patients, and it was higher in patients who received CCRT than in the RT alone group (19.6% vs. 6.3%, p=0.023). Conclusion Salvage RT alone as well as CCRT could be effective in patients with locoregionally recurrent esophageal cancer.

With the increasing emphasis on diversity, equity, and inclusion (DEI) in organizations and institutions, academic societies in gastroenterology and hepatology are beginning to take actionable steps toward achieving DEI. The successful implementation of DEI initiatives leads to excellence in the field, improved patient outcomes, particularly in areas where health disparities are prevalent, and advances in the gastrointestinal discipline. Such implementation also results in a workforce that better reflects the growing diversity of the population. This review defines DEI and introduces the DEI policies and strategies adopted by the academic societies of gastroenterology in other countries. This paper proposes strategies to integrate DEI better into the Korean Society of Gastroenterology, emphasizing the importance of embedding DEI into the culture and strategic framework. The key strategies include establishing a DEI committee, setting clear targets, and conducting formal assessments to measure DEI progress. This study focused on enhancing workforce diversity, particularly among women and young doctors, and advocates for the need to support their academic development through male allyship and the promotion of equitable and inclusive academic cultures.

Purpose: We investigated the results of endoscopic fenestration for deeply located intracranial cysts (DLICs), risk factors for reoperation, and symptom improvement. Materials and Methods: We included 51 patients with DLICs who underwent endoscopic fenestration between November 2006 and October 2022. The median age was 5±20 years (6 days–67 years), and 36 (70.6%) patients were aged <20 years. The male-tofemale ratio was 1.3:1. The ventriculoscope was used to fenestrate the cysts, which had diameters under 4.5 mm. The volume of DLICs was measured separately on serial magnetic resonance imaging, and the patients were followed up for 32±40 months. Results: The mean preoperative volume of DLICs was 63.5±87.4 cm, 3 , which decreased to 23.7±56.2 cm 3postoperatively, with a 45.4%±32.1% decrease rate in 32 months. All DLICs were approached appropriately, avoiding the eloquent areas. Overall, 39 (76.5%) patients showed symptom improvement after a single operation, which was preserved without recurrence, whereas 12 (23.5%) underwent a second operation [shunting (17.6%) or repeating the endoscopic fenestration (5.9%)] owing to symptom aggravation and recurrent cysts. Patients aged <12 months showed 7.4 times more re-operation rate (p>0.046) and 7.4 times less symptom improvement (p=0.038) compared to those with older age. Females showed 6.5 times more re-operation rate (p=0.037) and 7.1 times less symptom improvement (p=0.027) than males. No patients experienced complications such as cerebrospinal fluid leakage, postoperative hemorrhage, or infection. Conclusion Endoscopic surgery is feasible for the treatment of DLICs. Female sex and age <12 months are risk factors for re-operation and less symptom improvement.

Background: The recent published Korean Working Group on Sarcopenia (KWGS) guideline includes the concept of functional sarcopenia. The study investigated the prevalence of sarcopenia and its association with health-related adverse outcomes defined by the KWGS in community-dwelling older adults. Methods: Data were sourced from the Korean Longitudinal Study on Health and Aging, focusing on Koreans 65 aged and above. The definitions of sarcopenia and functional sarcopenia followed the KWGS. The risks of falls, mobility limitation, and death were analyzed using logistic regression and Cox proportional hazard. Results: Of the 594 participants, 145 (24.4%) were classified as having functional sarcopenia and 129 (12.0%) with sarcopenia. Both showed an increased prevalence with age. Functional sarcopenia had higher risks of mobility limitation (odds ratio [OR]=3.461; 95% confidence interval [CI], 1.956–6.121) and mortality (hazard ratio [HR]=1.775; 95% CI, 1.229–2.564). Sarcopenia was associated with falls (OR=7.376; 95% CI, 1.500–36.272), mobility limitation (OR=2.057; 95% CI, 1.172–3.611) and mortality (HR=1.512; 95% CI, 1.054–2.169). Conclusion Functional sarcopenia is a prevalent condition that is associated with mobility limitation and mortality in community-dwelling older adults. This highlights the clinical relevance of functional sarcopenia and supports its inclusion in sarcopenia diagnosis.
