Primary care is a key component in building an efficient and sustainable healthcare system, providing comprehensive health management through a patient-centered approach. Countries worldwide continue to reform their primary care systems to enhance their effectiveness within diverse healthcare environments and socioeconomic contexts. Among them, Australia is recognized for its well-established primary care system. It provides universal health coverage through Medicare. General practitioners offer comprehensive medical services and play a pivotal role in Australia’s primary care system. To further support primary care, the Primary Health Networks (PHNs), a community-based medical service network, has been established. However, challenges remain, such as a shortage of workforce shortages and regional disparity in medical resources. To address these issues, the Australian government announced the “Primary Health Care 10 Year plan.” Through the efforts, Australia is expected to further strengthen its primary care system.

Anaplastic thyroid carcinoma (ATC) is a rare and highly aggressive malignancy typically associated with dismal outcomes. Most patients present with advanced disease, often precluding curative resection. We report a case of intrathyroidal ATC incidentally identified in a 72-year-old male who underwent diagnostic lobectomy for a low-suspicion, predominantly cystic huge thyroid nodule. Final pathology revealed a completely resected, intrathyroidal ATC without extrathyroidal extension. Postoperative imaging showed no evidence of residual or metastatic disease. Based on multidisciplinary discussion, the patient underwent completion thyroidectomy and central neck dissection without adjuvant therapy. No residual malignancy was identified, and the patient remains recurrence-free at six months. This case highlights that early-stage intrathyroidal ATC may present without overt malignant features and can be curatively treated with complete surgical excision. Careful evaluation and multidisciplinary decision-making are essential in managing rapidly enlarging thyroid nodules with atypical features.

Background/Aims: Exercise is a key component of the management of axial spondyloarthritis (axSpA), providing symptomatic relief and helping prevent ankylosis. However, there is a lack of quantitative studies evaluating daily exercise patterns in patients with axSpA. This study assessed the types, frequency, and duration of exercises performed by these patients through a structured questionnaire. Methods: This cross-sectional study included radiographic axSpA patients who visited a rheumatology clinic between September 2014 and March 2016 and provided informed consent to participate. The survey captured information on four types of exercise: high-intensity exercise, moderate-intensity exercise, strength training, and walking. Disease activity and functional status were evaluated using the Bath ankylosing spondylitis disease activity index (BASDAI) and the Bath ankylosing spondylitis functional index (BASFI), respectively. Results: A total of 645 patients participated in the study. Among them, 25.1% engaged in high-intensity exercise, 36.0% in moderate-intensity exercise, 81.2% in walking, and 32.8% in strength training. The median weekly exercise frequency was 3.0 days (interquartile range [IQR], 2.0-4.0) for high-intensity exercise, 3.0 days (IQR, 2.0-5.0) for moderate-intensity exercise, 5.5 days (IQR, 4.0-7.0) for walking, and 3.0 days (IQR, 2.0-5.0) for strength training. The median daily exercise duration was 60 minutes (IQR, 60-120) for high-intensity exercise, 60 minutes (IQR, 30-90) for moderate-intensity exercise, 30 minutes (IQR, 20-60) for walking, and 30 minutes (IQR, 20-60) for strength training. Comparisons by disease activity showed that BASFI scores were more strongly associated with differences in exercise patterns than BASDAI scores. Conclusion Radiographic axSpA patients predominantly engaged in low-intensity activities, particularly walking, typically for short durations. Given the observed variations in exercise patterns based on disease activity, personalized exercise education and guidance should be prioritized in clinical practice to optimize axSpA management.

The use of miniscrew-assisted rapid palatal expansion (MARPE) has yielded successful outcomes in late adolescence and early adulthood, particularly in correcting transverse maxillary discrepancies and enhancing airway expansion. This report presents three cases of children at different dentition stages treated with MARPE. In one patient with severe crowding, MARPE enabled dental alignment without the need for premolar extractions. Additionally, MARPE combined with facemask therapy improved the patient’s facial profile, resulting in high patient and guardian satisfaction. These cases highlight MARPE’s potential as an effective treatment for maxillary discrepancies and severe arch length discrepancies in children.

Objectives: Clinical situations that make it challenging to differentiate odontogenic cysts from non-odontogenic cysts and benign tumors of the jaw include cases with cystic conditions accompanied by secondary infection, impacted teeth, cortical thinning and expansion, or external root resorption.This study aimed to identify risk factors for complications in patients undergoing cyst enucleation of the jaw, propose a clinical model, and determine the necessary indications for preoperative root canal of adjacent teeth. Materials and Methods: A review of surgical, pathological, and radiological reports, as well as medical records, was conducted. Pathological diagnosis, lesion size, history of preoperative endodontic treatment of the adjacent tooth, operator details, surgical procedures, age, gender, and complications (with severity) were analyzed. Results: This study involved 77 patients (55 men, 22 women) and found 10 complications. Procedure type (cyst enucleation only, apicoectomy and bone graft, or bone graft only) and lesion size were significant risk factors. Preoperative root canal therapy and men gender also tended to positively correlate with complications, while age was not a factor. Conclusion Within the limitations of our study, additional procedures contributed to lower risk of complications with the exception of bone graft.A large cyst size was also associated with a higher risk of complications. It is important to consider the possibility of a second procedure and take thorough precautions to prevent infection when performing bone grafts. Patients should be informed of these risks in advance, scheduled for regular follow-up, and provided additional treatment when necessary.

The population attributable fraction (PAF) indicates the proportion of disease cases in a given population that can be attributed to a specific factor, assuming a causal relationship. In other words, it quantifies the extent to which that factor contributes to disease occurrence. PAF calculation methods have been applied to studies factors and several, studies have reported PAFs for dietary contributors to overall or specific cancer risks. Our team has conducted several PAF studies and presents findings on the contributions of dietary factors to cancer risk in the Korean population.Current Concepts: For colorectal cancer, the PAF of dietary factors is 34.9%, with insufficient whole grain intake contributing the largest share (16.6%). For gastric cancer, dietary factors have a PAF of 18.6%, with excessive intake of salted vegetables contributing the most (16.0%). Notably, the PAFs for inadequate whole grain and milk consumption were higher than those reported in previous studies, while the PAFs for other dietary factors fell within the expected range. These findings emphasize the need to prioritize interventions that effectively reduce the diet-attributable cancer burden.Discussion and Conclusion: Country-specific PAF estimates are crucial for developing effective cancer prevention strategies tailored to the Korean population. To better apply dietary PAF estimates, future studies should (1) integrate data from existing and ongoing cohort studies to determine Korea-specific relative risks, (2) estimate dietary prevalence using assessment tools that capture long-term dietary habits, and (3) establish optimal intake levels specific to the Korean context.

Cerebellar ataxia, neuropathy, and vestibular areflexia syndrome (CANVAS) is a neurodegenerative disorder caused by a biallelic expansion of pentanucleotide repeats in the RFC1 gene. Previous studies have reported up to 22% of patients with late-onset ataxia harbor this pathogenic repeat expansion. Despite its relatively high prevalence, CANVAS is often underdiagnosed because the disease is not well recognized and genetic testing is not performed in clinical practice. Here, we present a patient with characteristic clinical features, confirmed by genetic testing.

Background: Despite the critical importance of sleep medicine within neurology, notable gaps in education and clinical practice persist among neurologists. This study aims to explore the extent of involvement and the challenges faced by Korean neurologists in sleep medicine, focusing on awareness of polysomnography training program, the operation of sleep study facilities, and educational exposure. Methods: An online survey collected responses from 233 neurologists, focusing on their demographics, knowledge of and involvement in sleep medicine, operation of sleep study facilities, and participation in residency training. Results: The findings indicated that 84.9% of neurologists were aware of polysomnography training program, primarily through professional societies. Nonetheless, 15.1% reported unfamiliarity with these initiatives, with 72.7% of this subgroup expressing interest in sleep medicine yet lacking access to information. In terms of clinical practice, 74 neurologists operated sleep study facilities, with 63% intending to expand. Key operational challenges included staff management, maintaining patient volumes, and inadequate institutional support. Among respondents from teaching hospitals, only 36 out of 114 reported active resident involvement in sleep study interpretations, predominantly hindered by excessive workloads and insufficient staffing. Conclusions A significant number of neurologists have an interest in sleep medicine; however, substantial challenges impede effective education and clinical practice. These results underscore the need for improved educational resources and institutional support to enhance the growth and effectiveness of sleep medicine practices among neurologists.

A 45-year-old woman with a history of migraine experienced thunderclap headaches, after which cerebral vasospasm was confirmed by brain magnetic resonance angiography. Nimodipine treatment initially improved the headache, but moderate daily headaches persisted despite vasospasm resolution. Conventional headache medications including topiramate, propranolol and amitriptyline proved ineffective. Treatment with fremanezumab, a calcitonin gene-related peptide (CGRP)-targeted therapy, resulted in significant reduction of headache frequency and intensity after 3 months. This case suggests the potential effectiveness of CGRP inhibition for persistent headaches following reversible cerebral vasoconstriction syndrome.

Purpose: To evaluate the compatibility and usability of test results obtained from the IDRA and Keratograph 5M in clinical settings by comparing their performance in patients with dry eye disease. Methods: From December 27 to 30, 2022, a study was conducted on 30 patients diagnosed with dry eye utilizing both the Keratograph 5M and IDRA devices. The parameters compared and analyzed included lipid layer thickness, tear meniscus height, tear film break-up time, and meibography. A paired t-test was used for statistical comparison. The lipid layer thickness in the Keratograph 5M was graded on a scale from 0 to 4 based on thickness. Results: No significant differences were found between the two devices in tear film break-up time, tear meniscus height, and meibography (p = 0.148, 0.072, 0.124, respectively). However, the tear lipid layer thickness measured by IDRA showed a proportional relationship with the grade assigned by the Keratograph 5M (Kendall R = 0.217, p = 0.037; Spearman R = 0.260, p = 0.045). Conclusions The IDRA device offers the advantage of performing multiple dry eye tests; simultaneously, thereby saving time compared to the Keratograph 5M. Both devices can be used compatibly with IDRA particularly advantageous for providing a numerical value for tear lipid layer thickness which enhances the convenience of dry eye diagnosis and treatment.
