A Survey of the Awareness, Knowledge and Behavior of Hair Dye Use in a Korean Population with Gray Hair

BACKGROUND: Gray hair naturally develops in the process of human aging. Many people with gray hair periodically dye their hair. Hair dyeing products are widely used and they can cause adverse effects. Therefore, the user's knowledge and recognition about hair dyeing and related side effects are important. OBJECTIVE: The goal of this study was to lay the foundation for understanding, preventing and treating side effects caused by hair coloring products. METHODS: We conducted a questionnaire survey for adult males and females aged over 20 who had gray hair. A total of 500 subjects were included in this study and statistical analysis was performed. RESULTS: Large numbers of the people who had experience with hair dye (233 out of 319 people, 73.0%) did not know about the exact brand name of the hair dye product that they were using. Of 319 hair dye users, 23.8% (76 out of 319) people stated that they experienced side effects. Despite the occurrence of side effects from hair dyeing products, it seems they did not realize the seriousness of the side effects or the need for treatment. CONCLUSION: It is advisable to introduce a system that enables users to become aware of the ingredients and side effects of hair coloring products and give opportunities for users to become aware of the side effects of hair coloring through education, publicity and publication of an informational booklet.

Multiple Granulocytic Sarcomas in a Patient with Longstanding Complete Remission of Acute Myelogenous Leukemia

Granulocytic sarcoma is an extramedullary tumor composed of granulocytic precursor cells. It usually presents as a nodular mass in the course of acute myelogenous leukemia. Rarely, the tumor develops in non-hematological conditions or in a patient with complete remission from the acute myelogenous leukemia. In such cases, aleukemic granulocytic sarcoma can be a preceding sign of systemic leukemia or a first sign of hematologic relapse of leukemia. We present an unusual case of multiple granulocytic sarcomas developed in a patient with longstanding complete remission of acute myelogenous leukemia, who has not had bone marrow and peripheral blood involvement for a long time.

Three Cases of Pseudopelade of Brocq that Had Been Misdiagnosed as Seborrheic Dermatitis / 대한피부과학회지

Pseudopelade of Brocq is a rare, idiopathic, slowly progressive hair disorder that results in cicatricial alopecia. It is characterized by multiple, small, discrete, asymmetrical, smooth alopecic patches that show little clinical inflammation. Mild pruritus and diminished lesional sensation may also be present. In addition, mild perifollicular erythema may be detected. Seborrheic dermatitis presents as chronic, papular, scaly lesion of skin, and this can be seen on the scalp. Clinically, this disease is characterized by oily, erythematous, scaly lesion. Although both diseases originally have different clinical characteristics, the early and mild scalp lesions of both diseases sometimes mimic each other. Herein, we report on 3 cases of pseudopelade of Brocq that were misdiagnosed and treated as seborrheic dermatitis.
