Patients with ectodermal dysplasia often have atrophied alveolar bone and an inadequate maxillomandibular relationship owing to congenital edentulism.Accurate implant placement that can overcomes anatomical limitations and orthognathic surgery to improve the maxillomandibular relationship is necessary for creating implant-supported prosthesis for these patients. Implant placement and provisional prosthesis fabrication before orthognathic surgery can provide critical fixed reference points and ensure accuracy during orthognathic surgery.In our patient, a digital system was used to design a surgical guide that considered the predictable position of the definitive prosthesis, allowing the placement of implants to overcome anatomical limitations and the creation of fixed reference points via the delivery of a provisional prosthesis for effective orthognathic surgery. The lack of compensation during orthognathic surgery was considered in the definitive prosthesis. As a result, a prosthesis with a minimal anterior cantilever was fabricated. This study aimed to determine the appropriate sequence of multidisciplinary collaborations that would, result in the best functional and aesthetic outcomes.

The introduction of anti-amyloid therapies for Alzheimer’s disease (AD), such as lecanemab (Lequembi®), which was recently approved in Korea, necessitates careful monitoring for amyloid-related imaging abnormalities (ARIA) using brain MRI. To optimize ARIA monitoring in Korean clinical settings, the Korean Society of Neuroradiology (KSNR) and the Age and Neurodegeneration Imaging (ANDI) Study Group proposed MRI protocol recommendations on essential MR sequences, MRI acquisition parameters, timing and condition of MRI examinations, and essential details to provide a scientific basis for maximizing the safety and efficacy of AD treatment. A customized, standardized MRI protocol focusing on Korea’s healthcare environment can improve ARIA management and ensure patient safety through early detection of potential anti-amyloid therapy side effects, thereby enhancing treatment quality.

Background: Cutaneous angiosarcoma, a rare malignant tumor, is associated with high mortality and poor prognosis. Objective: This study aimed to analyze the clinicopathologic features of cutaneous angiosarcoma and identify the prognostic factors influencing survival. Methods: Medical records of patients diagnosed with cutaneous angiosarcoma between January 1995 and March 2023 were retrospectively reviewed. Demographic data, clinicopathologic features, and treatment modalities were analyzed to evaluate the correlation with overall survival (OS) and progression-free survival (PFS). A total of 70 patients were included in the study. Results: Their mean age at diagnosis was 71 years (range, 41–91 years). Of them, 57 (81.4%) were males. Five-year OS and PFS rates were 29.0% and 10.7%, respectively. In univariate analysis, a mass in the frontal area of the scalp showed significant associations with poorer PFS (hazard ratio [HR], 1.95; 95% confidence interval [CI], 1.07–3.55; p=0.029) and poorer OS (HR, 2.42; 95% CI, 1.22–4.80; p=0.011). Mass size exceeding 3 cm had a notable impact on PFS (HR, 3.41; 95% CI, 1.32–8.82; p=0.011) and remained a significant independent adverse prognosticator in multivariate analysis (HR, 4.55; 95% CI, 1.22–16.99; p=0.024). Conclusion Cutaneous angiosarcoma is characterized by an unfavorable prognosis, with a larger mass size identified as an independent prognostic factor.

Parkinson’s disease (PD) is a neurodegenerative disease caused by the death of dopaminergic neurons in the nigrostriatal pathway, leading to motor and non-motor dysfunctions, such as depression, olfactory dysfunction, and memory impairment. Although levodopa (L-dopa) has been the gold standard PD treatment for decades, it only relieves motor symptoms and has no effect on non-motor symptoms or disease progression. Prior studies have reported that 6-shogaol, the active ingredient in ginger, exerts a protective effect on dopaminergic neurons by suppressing neuroinflammation in PD mice. This study investigated whether cotreatment with 6-shogaol and L-dopa could attenuate both motor and non-motor symptoms and dopaminergic neuronal damage.Both 6-shogaol (20 mg/kg) and L-dopa (80 mg/kg) were orally administered to 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine/probenecid-induced PD model mice for 26 days. The experimental results showed that L-dopa alleviated motor symptoms, but had no significant effect on non-motor symptoms, loss of dopaminergic neuron, or neuroinflammation. However, when mice were treated with 6-shogaol alone or in combination with L-dopa, an amelioration in both motor and non-motor symptoms such as depressionlike behavior, olfactory dysfunction and memory impairment was observed. Moreover, 6-shogaol-only or co-treatment of 6-shogaol with L-dopa protected dopaminergic neurons in the striatum and reduced neuroinflammation in the striatum and substantia nigra.Overall, these results suggest that 6-shogaol can effectively complement L-dopa by improving non-motor dysfunction and restoring dopaminergic neurons via suppressing neuroinflammation.
