#atopic dermatitis, #allergy, #itching, #eczema, #pollen, #house dust mites, #moisturizing, #steroid ointment

Atopic dermatitis is a chronic skin condition in which allergic mechanisms cause ongoing inflammation of the skin. It causes severe itching and recurring eczema, and the skin can become thick and rough (lichenification). It tends to occur when a person with a genetic predisposition is exposed to allergy triggers, and symptoms can worsen with spring pollen, house dust mites, and fine particulate matter. If symptoms persist, please consult an allergist or a dermatologist.

A colon polyp is a benign growth that forms in the colon. Most cause no symptoms and are found incidentally during a colonoscopy. Because some polyps can develop into colorectal cancer, the standard practice is to remove them when they are found. If you are age 40 or older, please have regular colonoscopy screenings.

Diabetic Retinopathy

Diabetic retinopathy is a condition in which prolonged high blood sugar damages the tiny blood vessels and nerve tissue of the retina, the light-sensing layer inside the eye. About 15 to 30% of diabetic patients in Korea have this condition, and it is important to have an annual eye exam even without symptoms. Diabetic retinopathy is one of the three leading causes of blindness in Korea, so early detection and appropriate treatment are essential to protecting your vision.

Gastric Submucosal Tumor

#Gastric submucosal tumor, #GIST, #Myoma, #Lipoma, #Upper endoscopy, #Endoscopic ultrasound, #Biopsy

A gastric submucosal tumor is a growth that forms beneath the inner lining (mucosa) of the stomach. It is found in about 1 to 2 out of every 100 people who undergo an upper endoscopy, and most are benign (not harmful to the body). However, some can become malignant, so regular follow-up is needed. If one is found during an endoscopy, please follow your doctor's guidance for management.

Treatment continues for a long period, and consultation with an experienced pediatric endocrinology specialist is needed.

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.

A high-risk pregnancy is a pregnancy with a higher chance than usual of adversely affecting the mother and the fetus. Advanced maternal age (35 or older) is one risk factor for a high-risk pregnancy. Recognizing your own risk factors and following your medical team's guidance can help lead to a good outcome.

Kidney Transplant Process

#kidney transplantation, #kidney transplant, #living-donor kidney transplantation, #deceased-donor kidney transplantation, #immunosuppressants, #rejection, #end-stage kidney failure, #KONOS, #organ transplantation, #double vision, #overlapping images

Kidney transplantation is a surgery that transplants a healthy kidney into the body to replace a kidney that has lost its function. Unlike dialysis, it can restore most of the kidney's various functions (removing waste products, regulating electrolytes, secreting hormones that stimulate blood cell production, and others), which makes it one of the main treatment options for end-stage kidney failure. Whether and how to have a transplant depends on each patient's health condition, so please be sure to decide through consultation with a medical specialist.

Macular Degeneration

Macular degeneration is a condition in which the macula — the central part of the retina — is damaged, leading to decreased vision. In severe cases it can lead to blindness, but early detection and consistent treatment can help slow its progression. If you are 50 or older, please have regular retinal examinations.

Malocclusion and Orthodontic Treatment

#malocclusion, #orthodontics, #orthodontic treatment, #open bite, #deep bite, #anterior crossbite, #clear aligners, #brackets, #tooth alignment

Malocclusion is a condition in which the upper and lower teeth do not fit together correctly. When the teeth fit together well, it is easier to chew food effectively, speak clearly, and maintain a natural appearance. Leaving malocclusion untreated may reduce chewing efficiency and make tooth decay and gum disease more likely, so an accurate diagnosis and treatment at an appropriate time are important. Please consult an orthodontic specialist to decide whether and when to begin orthodontic treatment.

In childhood, teeth that are misaligned or an upper and lower bite that does not fit together properly can make chewing uncomfortable and cause problems with speech. They can also affect facial growth. If you suspect your child has a dental problem, please consult a dental specialist.
