Objectives: This study aims to evaluate the accuracy and effectiveness of temporomandibular joint (TMJ) arthrocentesis using the three-dimensional (3D)-printed TMJ injection guide in cases of hemarthrosis caused by condyle fractures. Materials and Methods: A retrospective chart review was conducted for patients treated with the customized TMJ arthrocentesis guide to address hemarthrosis. Inclusion criteria included adults older than 18 years with condylar fractures not indicated for open reduction and internal fixation. The guide was fabricated using computed tomography or cone-beam computed tomography scans and 3D printing to control the degree and depth of the needle through the guide to aspirate hemarthrosis. Results: Six joints from five patients (average age 52.4 years) were treated using the guide. Post-procedural magnetic resonance imaging confirmed complete resolution of hemarthrosis in all cases. A representative case demonstrated successful outcomes with normal healing and no complications at 8 months post-procedure. Conclusion The customized TMJ injection guide, using ear-based reference points, significantly enhances the accuracy and safety of TMJ arthrocentesis. This innovation is expected to increase the accessibility and effectiveness of TMJ-related treatments for clinicians without specialized TMJ expertise.

Purpose: The adjusted Global Antiphospholipid Syndrome (APS) Score (aGAPSS) was developed for assessing the probability of thrombotic events in APS patients. This study investigated whether the aGAPSS at diagnosis was associated with poor outcomes during follow-up in patients with antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV). Materials and Methods: This study included 170 AAV patients who had the results of APS-related antibodies at diagnosis but were not diagnosed with APS. All-cause mortality, end-stage kidney disease (ESKD), cerebrovascular accident, and acute coronary syndrome were considered poor AAV outcomes. The aGAPSS comprises five items, with 5, 4, 4, 3, and 1 points assigned to anticardiolipin antibodies, anti-β2-glycoprotein 1 antibodies, lupus anticoagulants, hyperlipidaemia, and arterial hypertension at AAV diagnosis, respectively. Results: The median age of the 170 patients [93 microscopic polyangiitis (MPA), 44 granulomatosis with polyangiitis (GPA), and 33 eosinophilic GPA (EGPA)] was 63.0 years. The optimal cut-off of the aGAPSS at diagnosis for ESKD during follow-up was set as two using the receiver operating characteristic curve. AAV patients with an aGAPSS ≥2 at diagnosis exhibited a significantly reduced ESKD-free survival rate compared to those with an aGAPSS <2 at diagnosis (p=0.045). Additionally, MPA and GPA patients, excluding EGPA patients for whom the median aGAPSS at diagnosis was close to 0, also showed similar patterns to the results among the 170 patients with AAV (p=0.021). Conclusion This study is the first to demonstrate that the aGAPSS at diagnosis was significantly associated with ESKD during follow-up in AAV patients without APS.

Objectives: Dextrose prolotherapy is one of the most promising minimally invasive interventions for temporomandibular disorder (TMD), particularly in refractory cases where other conservative treatments have failed. The purpose of this study was to demonstrate the efficacy of a new treatment, temporomandibular joint (TMJ) prolotherapy, in patients with TMD to alleviate symptoms. Materials and Methods: A retrospective analysis was conducted on TMD patients with chronic pain who did not respond to conventional treatments. TMJ prolotherapy was performed using hypertonic dextrose in the TMJ area, targeting the retrodiscal attachment tissue, anterior disc attachment tissue, lateral capsule, origin of the masseter muscle, and the stylomandibular ligament. Pain or discomfort intensity in the TMJ was evaluated using a numerical rating scale (NRS). Maximum mouth opening and subjective satisfaction were also analyzed. Results: Nineteen patients (6 males, 13 females, average age 43 years) participated in this study. All patients experienced pain improvement with a maximum of three prolotherapy sessions. The initial mean NRS was 5.7, which ultimately decreased to a final mean TMJ discomfort score of 1.7 postintervention. The patients’ maximum mouth opening increased from an initial 34.5 mm to 38.8 mm, and they reported positive satisfaction with the prolotherapy treatment. The clinical outcomes were positive regardless of main origin of TMD symptoms. Conclusion Hypertonic TMJ prolotherapy is an effective minimally invasive intervention for TMJ disorders with chronic pain.

Background: The increasing rate of excess body weight (EBW) in the global population has led to growing health concerns, including cancer-related EBW. We aimed to estimate the population attributable fraction (PAF) of cancer incidence and deaths linked to EBW in Korean individuals from 2015 to 2030 and to compare its value with various body mass index cutoffs. Methods: Levin’s formula was used to calculate the PAF; the prevalence rates were computed using the Korean National Health and Nutrition Examination Survey data, while the relative risks of specific cancers related to EBW were estimated based on the results of Korean cohort studies. To account for the 15-year latency period when estimating the PAF in 2020, the prevalence rates from 2015 and attributable cases or deaths from 2020 were used. Results: The PAF attributed to EBW was similar for both cancer incidence and deaths using either the World Health Organization (WHO) Asian-Pacific region standard or a modified Asian standard, with the WHO standard yielding the lowest values. In the Korean population, the PAFs of EBW for cancer incidence were 2.96% in men and 3.61% in women, while those for cancer deaths were 0.67% in men and 3.06% in women in 2020. Additionally, PAFs showed a gradual increase in both sexes until 2030. Conclusion The EBW continues to have a significant impact on cancer incidence and deaths in Korea. Effective prevention strategies targeting the reduction of this modifiable risk factor can substantially decrease the cancer burden.
