High incidence in spring and summer when UV rays are strong
Possibility of metastasis to malignant virus
Bone marrow transplantation and lymphocyte removal
Epstein-Barr virus, also called human herpesvirus, is a DNA virus with a double-stranded structure. The Epstein-Barr virus uses the human body as a host to expand its contagiousness, and is so contagious that it can be said that more than 90% of the total population is infected. When the virus enters the human body, it remains inactive, making it difficult to detect early. If you are infected with Epstein-Barr virus, it is highly likely that you will be infected with malignant lymphoma.
Vesicular bullous lymphoproliferative disease
Epstein-Barr virus, unlike COVID-19, is a familiar virus that has been well known to humans for a long time. Anyone is infected so that more than 90% of adults have positive antibodies to this virus. Fortunately, most of them do not have any symptoms even if they become infected, and only a few cause infectious mononucleosis, but most of them return to normal. Epstein-Barr virus infects B lymphocytes through receptors on the surface of B lymphocytes. Rarely, T or NK cells. infection can cause NK/T-cell lymphoma, NK-cell leukemia, and chronic active EBV disease common in children.
A case of Epstein-Barr virus transmission
A 7-year-old boy presented to the dermatologist with a blistering lesion on his face. He developed a general reddened skin on both cheeks along with itching following being exposed to strong sunlight for a sports day 7 days before coming to the hospital and developing multiple, rice-grain-sized blistering rashes. At the same time a year ago, following exposure to the sun, small blisters appeared and lasted for 1-2 weeks.
The patient underwent a skin biopsy at the dermatology department, and the pathological examination confirmed a diagnostic skin change for this disease.
The importance of early detection and prompt treatment
When a patient is exposed to sunlight, the latent Epstein-Barr virus is activated to form a bullous lesion on the skin. The symptoms worsen in spring and summer when ultraviolet rays are strong. The silver blister heals with a dent in the center, leaving a small scar. Each time it is exposed to sunlight, the process of blisters and scarring is repeated. In some patients, the disease is limited to the skin, so life is not affected, but in some patients, metastasis to malignant lymphoma or leukemia, or death from hematocytosis. The course of the disease depends on the patient’s immune capacity and the nature of the infected virus, and there is no way to know which patient will progress to malignancy. Therefore, it is necessary to distinguish it from other bullous lesions occurring in children. It is essential to recognize the history of sun exposure and bullous lesions, and to prove the infiltration of Epstein-Barr virus-infected lymphocytes in the pathological examination of the skin biopsy. This disease requires a bone marrow transplant to remove all Epstein-Barr virus-positive lymphocytes from the body.

Rotator cuff syndrome similar to frozen shoulder
The most common degenerative shoulder diseases include frozen shoulder and rotator cuff syndrome. The two diseases have similar symptoms and are often mistaken for the same pain area. The rotator cuff is a collective term for muscles and tendons that surround and protect the shoulder joint and help it move. Various abnormalities such as inflammation, tendon damage, and rupture occurring in the rotator cuff that play this role are collectively called ‘rotator cuff syndrome’.
The onset of rotator cuff syndrome varies from person to person, but the following symptoms appear: When the arm develops rotator cuff syndrome, the symptoms vary from person to person, but the following symptoms appear. △ The arm moves well, but pain occurs in certain postures. The pain gets worse at night, to the point of insomnia. △ When the shoulder is rotated, it makes a rubbing sound. It is difficult to put your hands behind your back. △ After excessive exercise, pain occurs in the front of the shoulder or in the outer booth, and pain occurs to the middle of the arm. Damage to the rotator cuff can be caused by excessive use of muscles or tendons due to excessive exercise, resulting in inflammation or muscle damage.
The difference between rotator cuff syndrome and frozen shoulder is that both active and passive shoulder movements are restricted in the frozen shoulder, but passive movement is possible in rotator cuff syndrome. In addition, the rotator cuff syndrome is accompanied by muscle weakness in the shoulder, but the frozen shoulder is not accompanied by muscle weakness. If the shoulder rotator cuff is damaged, it is difficult to lift an object due to muscle weakness, and there is a difference in the range of motion when moving with and without force.
The major cause of rotator cuff syndrome is degenerative changes due to aging. Other than that, there are various other injuries, such as trauma and sports injuries. It is especially common in housewives who frequently use their shoulders and arms. To prevent chronic rotator cuff syndrome, mistaken for a frozen shoulder, it is most important to strengthen the shoulder joint through regular shoulder exercises. Stretch before starting exercise to reduce the risk of shoulder muscle damage, and avoid repetitive and excessive exercise. It is also important to manage hypertension, obesity, and smoking. In particular, diabetes mellitus requires glycemic control as it is highly correlated with adhesive arthritis, which is often accompanied by rotator cuff syndrome.
