Carpal tunnel syndrome (CTS) is a common form of hand mononeuropathy that is typi-cally caused by median nerve compression. Although it is often idiopathic, CTS can also result from various conditions, including space-occupying lesions. Tumoral calcinosis, a rare condition characterized by periarticular deposition of calcified masses, is an un-common cause of secondary CTS. We present a case of a 78-year-old woman with idio-pathic tumoral calcinosis that caused secondary CTS. Despite conservative treatments, her symptoms persisted, and diagnostic imaging, including radiographs, computed to-mography, and magnetic resonance imaging, revealed a calcified mass in the carpal tun-nel. A surgical intervention involving carpal tunnel release and excisional biopsy con-firmed the diagnosis of tumoral calcinosis. Postoperatively, the patient showed complete resolution of symptoms, with no recurrence on follow-up radiographs. This case high-lights the importance of considering space-occupying lesions, such as tumoral calcinosis, as a rare but treatable cause of secondary CTS.

Objective: To evaluate the effects of Capsosiphon fulvescens (C. fulvescens) ethanolic extract on inflammation in lipopolysaccharide (LPS)-induced RAW296.7 macrophages. Methods: The protective effects of C. fulvescens ethanolic extract on LPS-induced inflammation in RAW264.7 macrophages were assessed using biochemical analysis, including enzyme-linked immunosorbent assay, quantitative reverse transcription-polymerase chain reaction, and Western blot analysis. To examine reactive oxygen species (ROS) production, flow cytometry analysis, and immunofluorescence staining were used. Furthermore, the modulatory effect of C. fulvescens ethanolic extract on NF-κB activation was investigated. Results: C. fulvescens ethanolic extract significantly attenuated LPS-induced levels of pro-inflammatory cytokines and notably reduced the secretion and mRNA levels of LPS-mediated matrix metalloproteinases. In addition, C. fulvescens ethanolic extract decreased ROS production and suppressed the TLR4/NF-κB signaling pathway. Conclusions: C. fulvescens ethanolic extract alleviates inflammation as well as oxidative stress by modulating the TLR4/NF-κB signaling in LPS-induced RAW264.7 macrophages. C. fulvescens can be used as a potential therapeutic agent to suppress inflammation and oxidative stress-associated diseases.

Background and Objectives:
It is unknown whether the presence of low body mass index (BMI) influences the incidence of laryngeal cancer. In a national population-based study, we investigated their relationship retrospectively.Subjects and Method Using the data of Korean Health Insurance claims database, we selected adults aged 20 years or older who underwent a national health examination from January 1, 2007 to December 31, 2008 and were followed up until 2015 for the occurrence of laryngeal cancer. The hazard ratio of laryngeal cancer according to BMI and smoking status in the subjects was analyzed and adjusted for factors such as age, sex, alcohol consumption, and exercise status.
Results:
Finally, a total of 13675470 subjects were included in the study, and we found that laryngeal cancer occurred in 3731 of those subjects. The risk of developing laryngeal cancer was significantly associated with underweight (BMI <18.5 kg/m2) even after adjustment (hazard ratio of 1.27; 95% confidence interval of 1.11-1.46). There was also a difference according to smoking status. Underweight was not associated with laryngeal cancer in never-smokers, but in ex-smokers and current smokers.
Conclusion
Being underweight can increase the risk of laryngeal cancer. In particular, this risk can increase if you drink and smoke at the same time.

PURPOSE:
This study aimed to compare the accuracy of an alternative scan path with that of traditional scan paths to obtain a more accurate method for complete arch scans.
MATERIALS AND METHODS:
A mandibular stone cast, including tooth preparations for the inlay, crown, and fixed prosthesis, was scanned 10 times using four different scan paths (A, B, C, and D). The scans were converted into stereolithography files, resized, and superimposed onto a control file obtained from a desktop scanner. The scan time, total surface deviation, and local deviation of the mandibular teeth were measured. One-way analysis of variance (ANOVA) and Welch ANOVA were used for statistical analyses (α = .05). The relative standard deviation and standard error of the mean were calculated to evaluate accuracy.
RESULTS:
The total surface deviation differed significantly according to the scanning path despite a similar scan time. Path D had the highest accuracy and the most uniform color maps, showing minimal deformation of the digital model. Meanwhile, no significant differences were found in the local deviations in the individual tooth assessments, likely owing to issues with the superimposition method.
CONCLUSION
Among all scan paths, the scan path with the shortest distance from the starting point to the end point showed the smallest total surface deviation and the highest accuracy. No differences were observed in the deviations of specific teeth based on the scan path.
