Intracranial hypotension typically presents with orthostatic headache caused by cerebrospinal fluid (CSF) hypovolemia, most commonly resulting from spontaneous or iatrogenic CSF leaks. Traumatic rupture of an occult congenital sacral meningocele following a minor injury is exceptionally rare and may be diagnostically challenging. We report the case of a 40-year-old woman in Korea who developed sudden severe orthostatic headache immediately after a minor coccygeal contusion. Magnetic resonance myelography demonstrated a 5.8-cm dural ectasia/meningocele at the S3 level with a focal CSF fistula extending into the presacral space, accompanied by a tethered cord and an intradural lipoma. Given the anticipated risks associated with definitive surgical repair, a targeted trans-sacrococcygeal epidural blood patch was administered, resulting in substantial symptomatic improvement. This case highlights that while most post-traumatic CSF leaks occur at the cervical or thoracic level, occult spinal dysraphism should be considered a rare predisposing factor in post-traumatic orthostatic headache, particularly when trauma involves the sacrococcygeal region or when standard imaging findings are unrevealing. This finding also suggests that targeted caudal epidural blood patches may serve as a reasonable and less invasive treatment option when surgical intervention carries a high risk.

Background: Clostridioides difficile infection (CDI) is one of the most common hospitalacquired infections, with its incidence and disease burden increasing markedly worldwide over the past decade. Methods: To assess the attributable costs of CDI in Korea, the expenses related to hospital management of CDI cases were computed. This analysis used data from the National Health Insurance Service–National Sample Cohort spanning a decade (2010–2019). The annual national burden of CDI was determined by combining the attributable cost per CDI case with the number of patients with CDI obtained from the Health Insurance Review and Assessment Service data. Results: The attributable costs of CDI were determined based on variations in the length of hospital stay and medical costs between patients with CDI and control patients. The mean length of hospital stay was significantly longer for patients with CDI than that for control patients: 43.06 vs. 14.76 days (a difference of 28.30 days, P < 0.001). The adjusted medical costs (2019 = 100) for cases of CDI and controls were 11,162 USD and 3,318 USD, respectively, with a significant difference of 7,843 USD (P < 0.001). The cost of CDI per case exhibited a noticeable annual increase from 2010 to 2019, despite an annual decreasing trend in length of hospital stay. The estimated national cost attributed to CDI was $28.9 million in 2010; however, it increased gradually each year, reaching $205.6 million in 2019 (a 600% increase over 10 years). Conclusion CDI is associated with substantial healthcare costs in Korea. The economic burden of CDI has gradually increased in South Korea.

Objectives: To apply a healthy dietary program with reduced sodium intake, developed using data from the Korea National Health and Nutrition Examination Survey (KNHANES), focusing on the sodium intake level and eating patterns. Methods: The program was implemented using a living lab model, an open innovation ecosystem for user-centered problem-solving. Analysis of the KNHANES data revealed that older age groups had a low energy intake but a high sodium intake, particularly among those who frequently dined out. The program was designed to improve sodium-reduction literacy and enhance practical competency. Over four weeks, 40 participants tracked their dietary intake and worked with a clinical nutritionist through a process of diagnosis, experience, improvement, and expansion. A self-administered survey was conducted before and after the program to assess effectiveness. Results: Participants were four teenagers (10%), 26 in their twenties (65%), and 10 aged ≥ 30 years (25%), with eight males (20%) and 32 females (80%). Post-program analysis showed significant improvements in sodium-related nutrition knowledge (P < 0.01), with increased agreement on adopting low-sodium intake practices (e.g., interest in sodium content, choosing lower-sodium foods). Nutrient intake analysis showed a decrease in energy, carbohydrates, lipids, and proteins (P < 0.001), with sodium intake decreasing from 3,382.37 mg/d to 2,119.05 mg/d (P < 0.001). Conclusion The community-based, living lab model for the sodium-reduction program effectively improved participant sodium-reduction literacy and practical competency, suggesting that step-by-step, autonomous learning, can reduce sodium intake and promote healthier eating habits.

In large posterosuperior rotator cuff tears, retear is more likely due to factors such as poor tendon quality, tendon loss, incomplete footprint coverage, and incomplete repair. To reduce the retear rate and promote healing, various strategies have been explored, including augmentation using a human acellular dermal matrix (HADM) allograft patch. However, the traditional patch augmentation with a suture-bridge configuration is complicated and time consuming. Another method to alleviate impingement between the repaired tendon and acromion, similar to the ballooning effect in the subacromial space, is the acromiograft technique. However, a thin acromion may lead to fractures, and such a graft is less likely to incorporate with the repaired tendon. To address these concerns, we developed a new technique that enhances healing through direct contact with the repaired tendon, alleviates impingement with a spacer effect, and simplifies the procedure while ensuring adequate medial coverage including the musculotendinous junction. This article describes our “patch cushioning technique” using an HADM allograft. The present report provides a purely technical description of the procedure.

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.

Objective: To develop and evaluate a deep learning model for automated segmentation and detection of bone metastasis on spinal MRI. Materials and Methods: We included whole spine MRI scans of adult patients with bone metastasis: 662 MRI series from 302 patients (63.5 ± 11.5 years; male:female, 151:151) from three study centers obtained between January 2015 and August 2021 for training and internal testing (random split into 536 and 126 series, respectively) and 49 MRI series from 20 patients (65.9 ± 11.5 years; male:female, 11:9) from another center obtained between January 2018 and August 2020 for external testing. Three sagittal MRI sequences, including non-contrast T1-weighted image (T1), contrast-enhanced T1-weighted Dixon fat-only image (FO), and contrast-enhanced fat-suppressed T1-weighted image (CE), were used. Seven models trained using the 2D and 3D U-Nets were developed with different combinations (T1, FO, CE, T1 + FO, T1 + CE, FO + CE, and T1 + FO + CE). The segmentation performance was evaluated using Dice coefficient, pixel-wise recall, and pixel-wise precision. The detection performance was analyzed using per-lesion sensitivity and a free-response receiver operating characteristic curve. The performance of the model was compared with that of five radiologists using the external test set. Results: The 2D U-Net T1 + CE model exhibited superior segmentation performance in the external test compared to the other models, with a Dice coefficient of 0.699 and pixel-wise recall of 0.653. The T1 + CE model achieved per-lesion sensitivities of 0.828 (497/600) and 0.857 (150/175) for metastases in the internal and external tests, respectively. The radiologists demonstrated a mean per-lesion sensitivity of 0.746 and a mean per-lesion positive predictive value of 0.701 in the external test. Conclusion The deep learning models proposed for automated segmentation and detection of bone metastases on spinal MRI demonstrated high diagnostic performance.

Objectives: This study aimed to present the Asia-Pacific consensus on long-term and sequential therapy for osteoporosis, offering evidence-based recommendations for the effective management of this chronic condition.The primary focus is on achieving optimal fracture prevention through a comprehensive, individualized approach. Methods: A panel of experts convened to develop consensus statements by synthesizing the current literature and leveraging clinical expertise. The review encompassed long-term anti-osteoporosis medication goals, first-line treatments for individuals at very high fracture risk, and the strategic integration of anabolic and anti resorptive agents in sequential therapy approaches. Results: The panelists reached a consensus on 12 statements. Key recommendations included advocating for anabolic agents as the first-line treatment for individuals at very high fracture risk and transitioning to anti resorptive agents following the completion of anabolic therapy. Anabolic therapy remains an option for in dividuals experiencing new fractures or persistent high fracture risk despite antiresorptive treatment. In cases of inadequate response, the consensus recommended considering a switch to more potent medications. The consensus also addressed the management of medication-related complications, proposing alternatives instead of discontinuation of treatment. Conclusions This consensus provides a comprehensive, cost-effective strategy for fracture prevention with an emphasis on shared decision-making and the incorporation of country-specific case management systems, such as fracture liaison services. It serves as a valuable guide for healthcare professionals in the Asia-Pacific region, contributing to the ongoing evolution of osteoporosis management.
