The maxillary anterior region is critical for esthetics and function, requiring precise analysis and restoration when damaged by trauma. This case report presents the restorative process using a digital workflow for a patient with anterior trauma. A 22-year-old female exhibited fractures and extrusive luxation of maxillary central incisors, diagnosed with pulp necrosis. After endodontic treatment, intraoral and facial scans were performed, and provisional and definitive restorations were digitally designed. Various shade-matching techniques were employed to achieve natural esthetics. The definitive prosthesis improved harmony between the incisal edge and lower lip, as well as tooth axis, length, and zenith position, fulfilling the patient’s esthetic demands. This case suggests that combining digital technology and gingivectomy with a minimally invasive approach enables esthetic and functional restoration of the maxillary anterior region.

Fecal impaction (FI) is a potentially fatal condition characterized by the accumulation of large, hardened fecal masses in the large intestine, resulting in mechanical obstruction. This condition is commonly observed in older adults but can also affect younger populations, particularly patients with psychiatric conditions who face increased risk due to medication side effects, autonomic dysfunction, and inadequate bowel management. This report describes two forensic autopsy cases of fatal FI in patients with neuropsychiatric disorders. The first case involved a 52-year-old man with mild intellectual disability who had received long-term psychiatric treatment. Autopsy findings included marked colonic dilation (maximum diameter >10 cm), ischemic mucosal changes, and a large fecal mass (~2,200 g) obstructing the sigmoid and descending colon. The second case involved a 25-year-old man with severe intellectual disability. Autopsy revealed severe colonic dilation (maximum diameter of 12 cm), extensive FI along rectum and descending colon, and no evidence of alternative causes of death. In both cases, death was attributed to mechanical intestinal obstruction secondary to FI. These cases highlight the forensic significance of FI as a cause of sudden death in patients with neuropsychiatric disorders. Symptoms such as paradoxical diarrhea may be misinterpreted, and the inadvertent use of contraindicated medications (e.g., antidiarrheals) can worsen the condition, contributing to fatal outcomes. Furthermore, forensic evaluation must assess whether inadequate medical intervention or neglect played a role in the progression of FI. Early recognition, proactive bowel management, and interdisciplinary collaboration are critical to preventing fatal events in high-risk patients with neuropsychiatric disorders.

Background/Aims: Krebs von den Lungen-6 (KL-6) is associated with prognosis in patients with COVID-19. However, there is limited data on the correlation between the prognosis of COVID-19 and varying KL-6 levels at different time points. We investigated the optimal cutoff values of the initial and peak serum KL-6 levels to predict mortality and evaluated their correlation with mortality. Methods: This retrospective cohort study collected data on serially collected serum KL-6 levels in patients hospitalized with COVID-19 between October 2020 and January 2022 at a single tertiary hospital in South Korea. The area under the receiver operating characteristic curve and Youden index were used to determine the cutoff points for the initial and peak KL-6 levels that best predicted 30-day mortality. The association between the initial and peak KL-6 values was assessed by univariate and multivariate logistic regression models. Results: A total of 349 patients were included in this study. The mean initial and peak KL-6 levels were significantly higher in the non-survivor group than in the survivor group. The initial and peak KL-6 values that best predicted 30-day mortality were 491.85 U/mL and 660.05 U/mL, respectively. An initial KL-6 level greater than 491.85 U/mL and a peak KL-6 level greater than 660.05 U/mL were significantly associated with 30-day mortality. Conclusions The initial and peak levels of KL-6 were significantly associated with 30-day mortality in hospitalized patients with COVID-19. These findings suggest that serially monitoring blood KL-6 levels could be a valuable prognostic indicator for COVID-19.
