Purpose: Whether subtotal or total colectomy with primary anastomosis (PA) is safer than Hartmann procedure (HP) for left-sided colon cancer obstruction or perforation remains controversial. The purpose of this study was to compare postoperative morbidity, mortality, and defecation frequency between PA and HP for left-sided colon cancer obstruction or perforation. Methods: This retrospective study enrolled 54 patients from January 2014 to February 2018 who underwent emergency surgery due to left-sided colon cancer obstruction or perforation. Results: PA was carried out in 20 patients while HP was performed for 34 patients. Thirty-day mortality did not show significant difference between the two groups (15.0% vs. 14.7%, P=1.000). No anastomotic leakage occurred in PA group while three (8.8%) cases of stump leakage occurred in HP group. Stoma repair was performed for 13 cases (44.8%) and stoma reformation was performed for one case in HP group (7.7%). Stoma related complications occurred in five cases (17.24%). For patients after stoma repair, defecation frequency at 3 months after operation was 2.91±2.88 times per day in PA group and 2.86±2.63 times per day in HP group. At 1 year after operation, defecation frequency was changed to 1.40±1.12 times per day in PA group and 1.17±0.39 times per day in HP group. Conclusion: Primary ileosigmoid or ileorectal anastomosis for left-sided colon cancer obstruction or perforation is safe, and shows similar outcome of defecation frequency compared to H

Purpose: We investigated the clinical features of Korean patients with retinal capillary hemangioblastoma (RCH) and genetic variants of the von Hippel-Lindau (VHL) gene. Methods: A retrospective analysis was performed on patients with RCH from 2003 to 2021 at Seoul National University Bundang Hospital. Sporadic and hereditary RCH associated with VHL disease were classified based on the specific tumors and family history. Clinical features, including the location and number of RCH and bilateral involvement, were investigated. Multiplex ligation-dependent probe amplification and direct sequencing targeting the VHL gene were performed for six RCH cases associated with VHL disease. Results: A total of 18 patients (23 eyes) were enrolled in this study. The mean age at diagnosis was 37 ± 15 years. Twelve patients had hereditary RCH associated with VHL disease, and six patients had sporadic RCH. All five patients with bilateral RCH were clinically diagnosed with VHL disease, and 13 patients had unilateral RCH. Juxtapapillary RCH was only observed in patients with VHL. The most common complication of RCH was the epiretinal membrane, followed by the subretinal fluid. Pathogenic variants were identified in four patients. All three patients with type 1 VHL had the well-known missense mutation p.Glu70Lys, and one patient with type 2 VHL had the nonsense mutation p.Trp88Ter. Conclusions: In Korean patients with RCH, bilateral involvement and juxtapapillary RCH are highly likely to be associated with VHL disease. Because RCH may be the first clinical manifestation in patients with VHL, active genetic testing of the VHL gene and systemic evaluation are required.

Background: Pseudoceramides are used in barrier repair therapy for atopic dermatitis (AD) and demonstrated to reduce the adverse effects of topical glucocorticoids (GC). Objectives: We investigated whether PC-9S, one of the pseudoceramides, can regulate the expression of PPARα and topical GC-induced 11ß-hydroxysteroid dehydrogenase type 1 (11βHSD1) in oxazolone(Ox)-induced AD mice model (Ox-AD mice). Methods: Ox-AD mice were topically treated with PC-9S- containing physiologic lipid mixture for 4 days, and PPARα expression was assessed by real-time PCR and immunohistochemistry. Then, Ox-AD mice were treated with topical GC for 4 days with or without PC-9S co-application, and 11βHSD1 expression was evaluated. Skin barrier functions, inflammation, and antimicrobial peptides (AMPs) expression were quantitated. Results: Topical PC-9S significantly increased PPARα expression, normalized TEWL and surface pH, and reduced mast cell infiltrates in Ox-AD mice. It also prevented the decline of AMPs expression in Ox-AD mice. PC-9S suppressed the topical GC-induced upregulation of 11βHSD1 and prevented the GC-induced epidermal atrophy, reduced loricrin expression, and impaired barrier recovery. Conclusion: Skin barrier repair activity and the anti-inflammatory activity of pseudoceramide PC-9S in AD mice model might be partly mediated by PPARα stimulation. Inhibition of 11βHSD1 by PC-9S might contribute to reducing adverse effects of topical GC therapy.
