#common cold, #upper respiratory infection, #runny nose, #nasal congestion, #pharyngitis, #tonsillitis, #fever, #cough, #antibiotics, #feverish, #having a fever, #high fever, #low-grade fever, #body shaking, #feeling cold and shivering, #chills, #dry cough, #persistent cough, #cough that won't stop, #stuffy nose, #clear runny nose, #yellow runny nose, #hand tremor, #body tremor

An acute upper respiratory infection is a condition in which a viral or bacterial infection causes inflammation in the upper airway, including the nose, tonsils, pharynx (throat), and larynx (voice box). It includes what is commonly called the "common cold." The main symptoms are runny nose, nasal congestion, sore throat, cough, and fever. Adequate fluids and rest are the basic treatment, but if you have a high fever or severe symptoms, please consult an ENT specialist.

Adenovirus Infection

Adenovirus is a virus that can cause infection in several parts of the body, including the respiratory tract, the eyes (conjunctiva), and the gastrointestinal tract. It mainly affects children, and infections occur throughout the year. Most cases recover with supportive (symptomatic) treatment, but people with weakened immunity can develop severe pneumonia, so caution is needed.

Adult Vaccination

As people age, their immune defenses against infectious diseases weaken, so vaccination is important. To get the right vaccines for your own health condition, please consult an infectious disease specialist before being vaccinated.

Air-conditioning sickness is a general term for the various physical symptoms that appear when air conditioners or other cooling devices are overused and the temperature difference between indoors and outdoors becomes large. It is not an officially defined medical diagnosis, but headache, fatigue, and digestive problems may occur. In most cases, symptoms may improve within a few days if use of cooling devices is reduced. If symptoms are severe or accompanied by a high fever, please consult a medical specialist.

Blood Cancer

#blood cancer, #leukemia, #multiple myeloma, #platelets, #bone marrow, #anemia, #chemotherapy, #hematopoietic stem cell transplantation

Blood cancer refers to cancer that arises in the bone marrow, the organ responsible for producing blood cells. The bone marrow makes three types of blood cells: white blood cells, red blood cells, and platelets. When the bone marrow malfunctions, abnormalities in the number, shape, or function of these cells can cause a variety of symptoms. Frequent nosebleeds or easy bruising can occur, but these symptoms do not necessarily mean a person has blood cancer. If abnormal results appear on a blood test, please consult a hematology-oncology specialist.

Chronic Renal Failure

#kidney transplantation, #chronic renal failure, #kidney, #end-stage renal disease, #hemodialysis, #immunosuppressants

The kidneys are important organs that filter waste products from the body and remove them in the urine. When a chronic disease has damaged the kidneys completely, a new kidney may need to be transplanted to sustain life. Lifelong careful management is needed even after transplantation, so please do not rely on this Health Encyclopedia alone; receive proper management through consultation with a transplant specialist.

The flu (influenza) is a respiratory infection caused by the influenza virus, and its cause and symptoms differ from those of the common cold. Annual vaccination is recommended each fall (September to November). If you develop symptoms such as high fever or severe muscle aches, please see a medical specialist.

Hematopoietic Stem Cell Transplantation (HSCT)

#hematopoietic stem cell transplantation, #bone marrow transplant, #autologous transplant, #allogeneic transplant, #graft-versus-host disease, #blood cancer, #leukemia, #lymphoma, #loose stool, #watery diarrhea, #frequent trips to the bathroom

Hematopoietic stem cell transplantation (HSCT) is a treatment that transplants hematopoietic stem cells, the cells that give rise to white blood cells, red blood cells, and platelets. It was previously known as bone marrow transplantation, but the name changed once it became possible to collect these cells from peripheral blood as well. It is mainly used to treat blood-related malignancies, and both the treatment process and follow-up care afterward are important.

Hepatitis B is a liver inflammation caused by the hepatitis B virus. In Korea, about 30% of cirrhosis cases and 45% of liver cancer cases are associated with hepatitis B. It can be managed with proper care, including vaccination and consistent treatment, and regular checkups are important to help keep it from progressing to cirrhosis or liver cancer.

Leukemia is a malignant tumor that arises from immature blood cells in the bone marrow. It is classified as acute or chronic, and as myeloid or lymphoid depending on the type of cell involved. Unlike in the past, advances in medicine, including targeted therapy, have expanded the treatment options. Please discuss the diagnosis and treatment plan thoroughly with a hematology-oncology specialist.

Multiple myeloma is a blood cancer in which cancer develops in plasma cells (the cells that make antibodies). It mainly occurs in older adults. Anemia, kidney failure, bone pain, and repeated fractures are characteristic symptoms. If you develop bone pain, repeated fractures of unknown cause, or anemia, please consult a hematology-oncology specialist.

Pneumonia in Older Adults

Pneumonia in older adults generally refers to pneumonia that occurs at age 65 or older. Pneumonia is inflammation of the lungs caused by infection with bacteria, viruses, or other organisms. More than 50% of people with pneumonia and more than 90% of people who die of pneumonia are aged 65 or older. In older adults, symptoms are often not obvious, so diagnosis is easily delayed. If you have suspected symptoms, please consult a pulmonology and allergy specialist immediately.
