Objectives: We encountered patients with a congenital cutaneous sinus tract in the sternoclavicular joint region, which we designate as "congenital sternoclavicular sinus (CSCS)." The aim of this investigation is to enhance recognition of this subtle yet noteworthy entity and develop standardized protocols for its management. Patients and Methods: Between 2013 and 2023, 172 patients, including 78 males and 94 females, were referred to our institution for the management of CSCS. Clinical charts were retrospectively reviewed. Results: The majority of patients (60.5%) were young children below 3 years of age, with only six adult patients and a median age of 27.5 months. The left side was implicated in 157 cases (91.3%). In 146 cases (84.9%), a faint skin streak was noted above the orifice. Yet, no pharyngeal sinus tracts were detected, either through barium swallow studies or direct laryngoscopy. All skin lesions featured a diminutive orifice near the sternoclavicular joint, with the tract extending deeply into the subcutaneous tissue and terminating blindly, short of entering the joint, after a distance of 10 mm (ranging from 5 to 21 mm). Histopathological analysis revealed that the epithelial lining predominantly consisted of stratified squamous epithelium (87.8%), with ciliated columnar epithelium accounting for the remaining 12.2%. Conclusions: CSCS, though infrequent, presents with distinctive pathological and clinical features. The condition predominantly affects the left sternoclavicular joint region, with the notable "skin streak sign" aiding in diagnosis. We considered CSCS as one disease entity of branchial arch anomalies. Complete surgical excision offers a definitive cure.

Background: Growing evidence suggests a link between vitamin K (VK) intake and depression, although the underlying mechanisms remain unclear. We aimed to investigate whether oxidative balance scores (OBS) mediate the association between VK intake and depression in participants from the National Health and Nutrition Examination Survey (NHANES) 2007-2018., Methods: We analyzed data from 30,408 individuals. Dietary VK intake served as the independent variable, depression symptoms as the outcome variable, and OBS as the mediator. Multivariable logistic regression and restricted cubic splines assessed the associations. Mediation analysis was conducted to evaluate the potential mediating role of OBS., Results: Higher dietary VK intake was associated with lower depression risk in the multivariate model. Compared to the lowest log2 VK quartile, those in the higher quartiles had significantly lower depression odds (Q3: OR 0.66, 95% CI 0.55-0.78; Q4: OR 0.64, 95% CI 0.52-0.78). Additionally, a 1-unit increase in log2 VK intake was associated with a 15% decrease in depression odds (OR 0.85, 95% CI 0.81-0.90). Restricted cubic splines revealed a non-linear relationship between log2 VK and depression (p for non-linearity <0.001). Notably, OBS mediated 26.09% ( p  < 0.001) of the association between log2 VK and depression., Conclusion: Higher VK intake is associated with reduced depression risk, potentially mediated by oxidative balance. Further research is warranted to confirm causality and elucidate the underlying mechanisms., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Wang, Huang, Feng, Xiao, Luo and Zhang.)
