Drug Treatment for Rheumatoid Arthritis

#rheumatoid arthritis, #antirheumatic drugs, #biologics, #JAK inhibitors, #small molecule inhibitors, #methotrexate, #targeted therapy, #immunosuppressants

Rheumatoid arthritis is a chronic disease in which the immune system attacks the body's own joints and causes inflammation. After diagnosis, drug treatment is started to reduce inflammation and slow disease progression. In recent years, in addition to conventional antirheumatic drugs, a variety of targeted therapies have come into use, including biologics and small molecule inhibitors (JAK inhibitors). Because each drug has different characteristics and side effects, please discuss treatment options thoroughly with your doctor before deciding on the approach that is right for you.

Early-Onset Dementia (Young-Onset Dementia)

#early-onset dementia, #young-onset dementia, #alcohol-related dementia, #lifestyle diseases, #vascular dementia

Dementia is not a disease that affects only older adults. Dementia that develops at a relatively young age, between 45 and 65, is called early-onset (presenile) dementia. Because it tends to progress faster than dementia in older adults, please consult a medical specialist without delay if symptoms occur.

#Facial flushing, #Flushing, #Rosacea, #UV exposure, #Vasodilation, #Face

Fine Dust (Particulate Matter) and Health

#particulate matter, #fine particulate matter (PM2.5), #Asian dust (yellow dust), #respiratory system, #mask, #KF80, #KF94, #asthma, #air pollution, #dry cough, #minor cough, #persistent cough

Fine dust consists of tiny particles floating in the air. It directly affects the respiratory tract, including the nose, bronchi, and lungs, and can also harm the whole body, including the heart, brain, and blood vessels, through the bloodstream. Long-term exposure increases the risk of asthma, reduced lung function, and cardiovascular and cerebrovascular disease. On days when fine dust levels are high, limit outdoor activities, and people at high risk are advised to wear a health protection mask.

Frostbite

#Frostbite, #Cold-related illness, #Chilblains, #Cold wave, #Necrosis, #Fingers, #Toes, #Winter health

Frostbite occurs when body tissue exposed to severe cold freezes. It most often affects exposed areas such as the fingers, toes, nose, and ears. In severe cases, the tissue can undergo necrosis (tissue death), which may require amputation of the affected body part. If you suspect frostbite, protect the area from refreezing and seek medical care right away.

Gallbladder Cancer

#gallbladder cancer, #bile duct cancer, #gallbladder, #gallstones, #cholecystitis, #abdominal ultrasound, #jaundice, #laparoscopy, #stomachache, #tummy ache, #bellyache, #pain inside the abdomen, #feeling of indigestion (food stuck), #bloated feeling in the stomach, #poor digestion

The gallbladder is a small pouch that temporarily stores the digestive fluid (bile) made in the liver. Gallbladder cancer, a malignant tumor that develops there, causes no obvious symptoms until the disease is quite advanced, which makes early detection very difficult. If you have persistent indigestion or abdominal pain, please do not dismiss it on your own; be sure to consult a medical specialist for an examination and detailed tests.

Head and neck cancer is a general term for malignant tumors that develop in the head and neck region, including the larynx, oral cavity, oropharynx, hypopharynx, nasal cavity, and nasopharynx. Because this area is involved in essential everyday functions such as breathing, swallowing, and speaking, treatment can be challenging. If you have a voice change lasting more than 6 weeks, a mouth sore that doesn't heal after 3 weeks, or a lump in the neck, please see an ENT (ear, nose, and throat) specialist.
