Chronic Obstructive Pulmonary Disease (COPD)

#COPD, #chronic obstructive pulmonary disease, #airway obstruction, #smoking, #pulmonary function test, #bronchodilator, #smoking cessation, #emphysema, #dry cough, #persistent minor cough, #cough that will not stop

Chronic obstructive pulmonary disease (COPD) is a chronic lung disease in which the airways (the passages through which air travels) gradually narrow, making breathing difficult. The leading cause is smoking. Airways that have narrowed are mostly not restored, so early detection and smoking cessation are especially important. If cough, sputum, or shortness of breath persists, please consult a pulmonology and allergy specialist.

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.

HPV (human papillomavirus) is well known as the virus that causes cervical cancer. However, HPV can cause head and neck cancer (cancer that develops in the head and neck area), oropharyngeal cancer, tonsil cancer, and anal and genital warts not only in women but also in men. The HPV vaccine can also help protect men. If you have HPV-related symptoms or are considering vaccination, please consult an otolaryngology (ENT) specialist.

Human papillomavirus (HPV) is a very common virus transmitted through skin-to-skin contact.

Kidney Transplantation

#kidney transplantation, #kidney transplant, #end-stage kidney failure, #immunosuppressants, #living-donor transplantation, #deceased-donor transplantation

Kidney transplantation is a surgery that transplants a healthy kidney into a patient with end-stage kidney failure, whose kidneys can no longer function properly. If the transplanted kidney functions normally, the patient may be freed from dialysis (a treatment that filters waste products from the blood using a machine), which can greatly improve quality of life. Ongoing care after surgery is very important, and please be sure to consult a medical specialist about anything related to transplantation.

If you have suspected symptoms, please consult a pulmonology and allergy specialist immediately.
