South Korea Issues First Cold Wave Alert of Fall, Warning of Surge in Heart and Stroke Risks
South Korea’s first cold wave advisory of the season has arrived alongside urgent public-health warnings: the sudden plunge in temperatures can trigger life-threatening cardiovascular events, especially in older adults and those with preexisting conditions.According to the Korea Disease Control and Prevention Agency (KDCA), 334 cold-related illnesses were reported nationwide during the 2024-2025 season, with eight fatalities. Hypothermia accounted for the majority of cases; patients aged 65 and older made up 54.8% of incidents and 87.5% of deaths. Beyond direct hypothermia, the sharp drop in
Restoring Front Teeth: Why Implants Are Key to Function and Aesthetics
Front teeth play a role far beyond simply cutting food; they shape the overall facial impression and harmony. They are also the first area that draws the eye during a smile or conversation. As a result, damage or loss of front teeth can lead not only to functional discomfort but also to diminished confidence due to aesthetic deficits. In such cases, dental implants, which restore function and form akin to natural teeth, are regarded as the most effective solution.Front tooth implants are among the more challenging procedures in oral care. This is because the alveolar bone—the bone supporting
Breakthrough Patch Delivers High-Dose Drugs to Lymph Nodes Without Needles, Seoul Researchers Say
SEOUL — Researchers at Asan Medical Center have developed a needle-free patch that rapidly shuttles large volumes of medication through the skin to lymph nodes, achieving effects comparable to traditional injections, according to a study released Monday.The device, dubbed a surface fluidic microneedle patch (SFMNP), uses nanoscale materials and capillary action to drive drugs spontaneously into the skin. In animal models, the patch delivered payloads to lymph nodes within 10 minutes of application, with drugs persisting in the body for more than two hours — outperforming conventional syringe
As Winter Winds Rise, Atopic Dermatitis Patients Battle Endless Itch and Sleepless Nights
Relentless itching day and night robs patients of sleep, leaving scratched skin oozing and scarred in a cycle of repeated suffering. Often dismissed as a mere skin condition, atopic dermatitis is in fact a chronic disorder rooted in immune dysregulation and impaired internal circulation.The disease weakens the skin barrier, rendering it hypersensitive to external irritants, while disrupted flow of heat and moisture inside the body exacerbates inflammation. Though visible on the surface, its core lies in blocked internal pathways. Central to recovery is restoring balance in the san jiao—or tri
As Winter Bites, Pet Kneecaps Slip: The Hidden Threat of Patellar Luxation in Dogs and Cats
As temperatures plummet, pet owners notice their dogs and cats moving stiffly, joints aching under the strain of cold. Veterinarians see a surge in visits for orthopedic issues, with one condition topping the list: patellar luxation, commonly known as a dislocated kneecap.The patella is a small, rounded bone at the front of the knee that glides in a groove on the femur, stabilizing the joint between the thigh and shin. When it slips out of this femoral trochlear groove—medially in most cases or laterally in some—the knee buckles, triggering pain and instability. Left unchecked, this seemingl
Sustained Cardiovascular Health in Your 30s Can Slash Risks of Heart, Brain, and Kidney Diseases by Up to 75% Later in Life, Study Finds
A new study has found that accumulating strong cardiovascular health practices during one's 30s—the prime of young adulthood—can substantially lower the risks of cardiovascular and cerebrovascular diseases, as well as kidney conditions, well into middle age and beyond.Researchers led by Professors Lee Ho-gyu and Ha Kyung-hwa from Yonsei University College of Medicine's Department of Preventive Medicine, along with Professor Ji Jong-hyun from Gangnam Severance Hospital, announced on the 24th that consistently upholding high levels of cardiovascular health in one's 30s could reduce the chances
Leg Numbness May Be a Warning From Compressed Nerves, Not Just Fatigue
Leg numbness is not always a sign of simple fatigue—it can be a red flag from irritated nerves. In particular, a herniated lumbar disk occurs when the disk protrudes and presses on nearby nerves, causing not only low back pain but also numbness in the legs, reduced sensation, and muscle weakness. Symptoms often begin subtly, with a stiff or pulling sensation in the lower back, but if they persist for more than two weeks or extend to the legs, a disk disorder should be suspected.A herniated lumbar disk results from displacement of the intervertebral disk between spinal bones, irritating nerves
The Hidden Toll of Stress: How Insomnia and Dizziness Are Linked — and What to Do About It
Office worker Lee, 42, has been battling dizziness and sleepless nights. A new work environment and crushing workload have left him tossing at night; during the day, staring at screens triggers neck stiffness, vertigo, nausea, and headaches. The vicious cycle of skimping on sleep has pushed his physical and mental exhaustion to the breaking point.Insomnia triggered by environmental shifts or accumulated stress falls into three main categories: difficulty falling asleep (sleep-onset insomnia), frequent awakenings (sleep-maintenance insomnia), and waking too early without returning to sleep (ear
Rotator Cuff Tears: Understanding Causes, Symptoms, and Treatment Options
The rotator cuff, a critical group of four tendons that stabilize and move the shoulder, is essential for arm function. When these tendons become damaged or torn, the consequences can be significant: restricted shoulder movement, persistent throbbing pain, and discomfort that worsens with specific motions, such as lifting the arm or rotating it at certain angles. Pain often intensifies at night, disrupting sleep, especially when lying on the affected side. These symptoms distinguish rotator cuff tears from common shoulder stiffness or adhesive capsulitis (often referred to as “frozen shoulder
Full-Arch Dental Implants: A Modern Solution for Tooth Loss
Losing multiple teeth due to aging, periodontal disease, or trauma affects far more than just the ability to chew. It impacts speech, facial aesthetics, and even overall systemic health. Notably, impaired chewing function can lead to nutritional deficiencies, accelerating health deterioration in older adults. Some studies also suggest a link between tooth loss and an increased risk of dementia. Tooth loss, therefore, is not merely a dental issue but a significant factor in diminishing quality of life, necessitating prompt and precise restorative treatment.Historically, dentures were the primar
