Endometriosis, a prevalent but debilitating condition affecting women, poses significant challenges in diagnosis and management. The current 2024 guideline, developed by the Korean Society of Endometriosis (KSE), builds upon the 2018 KSE guideline. This guideline aims to provide customized recommendations tailored to Korea’s unique clinical aspects and medical environment, and addresses key areas such as diagnosis, medical and surgical management, considerations for special populations, and its complex relationship with cancer.

Sensitive skin (SS) is increasingly recognized as a complex syndrome characterized by discomfort and heightened sensitivity to otherwise harmless stimuli, such as environmental changes, physical contact, and cosmetic products. This condition poses challenges in both diagnosis and treatment due to its variable presentation and subjective nature. The pathophysiological features of SS include neurogenic inflammation and small fiber neuropathy, largely driven by the hyperactivation of sensory nerves. This hyperactivation is closely associated with transient receptor potential (TRP) channels, particularly TRPV1, which contribute to the exaggerated sensory responses seen in SS. Furthermore, psychological factors like stress and anxiety, along with environmental stressors such as pollution and ultraviolet exposure, play significant roles in exacerbating symptoms. The diverse and individualized responses to stimuli make it difficult to establish standardized diagnostic criteria for SS, necessitating a combination of subjective diagnostic tools (e.g., the Sensitive Scale-10) and objective assessments (e.g., transepidermal water loss and lactic acid sting test) to accurately identify and assess SS. This paper provides a comprehensive review of SS, covering its definition, prevalence, pathogenesis, diagnostic challenges, and management strategies, and highlights the importance of personalized care in effectively managing SS and improving patient quality of life.

Objective: To evaluate the outcomes of drug-eluting bead transarterial chemoembolization (DEB-TACE) according to the size of the beads for the treatment of small hepatocellular carcinoma (HCC). Materials and Methods: This retrospective study included 212 patients with a single HCC ≤5 cm from five tertiary institutions. One hundred and nine patients were treated with 70–150-µm doxorubicin DEBs (group A), and 103 patients received 100–300-µm doxorubicin DEBs (group B). The initial tumor response (assessed between 3 weeks and 2 months after DEB-TACE), time to local tumor progression (TTLTP), restricted mean duration of complete response (RMDCR), rate of complications, incidence of post-embolization syndrome, and length of hospital stay were compared between the two groups.Logistic regression was used to analyze prognostic factors for initial tumor response. Results: The initial objective response rates were 91.7% (100/109) and 84.5% (87/103) for groups A and B, respectively (P = 0.101). In the subgroup analysis of tumors ≤3 cm, the initial objective response rates were 94.6% (53/56) and 78.0% (39/50) for groups A and B, respectively (P = 0.012). There was no significant difference in the TTLTP (median, 23.7 months for group A vs. 19.0 months for group B; P = 0.278 [log-rank], 0.190 [multivariable Cox regression]) or RMDCR at 24 months (11.4 months vs. 8.5 months, respectively; P = 0.088). In the subgroup analysis of tumors >3-cm, the RMDCR at 24 months was significantly longer in group A than in group B (11.8 months vs. 5.7 months, P = 0.024). The incidence of mild bile duct dilatation after DEB-TACE was significantly higher in group B than in group A (5.5% [6/109] vs. 18.4% [19/103], P = 0.003). Conclusion DEB-TACE using 70–150-µm microspheres demonstrated a higher initial objective response rate in ≤3-cm HCCs and a longer RMDCR at 24 months in 3.1–5-cm HCCs compared to larger DEBs (100–300-μm).

Objective: Classification guides the surgical approach and predicts prognosis. However, existing classifications of spinal schwannomas often result in a high ‘unclassified’ rate. Here, we aim to develop a new comprehensive classification for spinal schwannomas based on their presumed origin. We compared the new classification with the existing classifications regarding the rate of ‘unclassified’. Finally, we assessed the surgical strategies, outcomes, and complications according to each type of the new classification. Methods: A new classification with 9 types was created by analyzing the anatomy of spinal nerves and the origin of significant tumor portions and cystic components in preoperative magnetic resonance images. A total of 482 patients with spinal schwannomas were analyzed to compare our new classification with the existing classifications. We defined ‘unclassified’ as the inability to classify a patient with spinal schwannoma using the classification criteria. Surgical approaches and outcomes were also aligned with our new classification. Results: Our classification uniquely reported no ‘unclassified’ cases, indicating full applicability. Also, the classification has demonstrated usefulness in predicting the surgical outcome with the approach planned. Gross total removal rates reached 88.0% overall, with type 1 and type 2 tumors at 95.3% and 96.0% respectively. The approach varied with tumor type, with laminectomy predominantly used for types 1, 2, and 9, and facetectomy with posterior fixation used for type 3 tumors. Conclusion The new classification for spinal schwannomas based on presumed origin is applicable to all spinal schwannomas. It could help plan a surgical approach and predict its outcome, compared with existing classifications.
