Perception of Tattoos in South Korea: Analysis of Citizen Survey Data / 대한피부과학회지

Background@#Increasing numbers of individuals are getting tattoos in recent times; however, the possible adverse effects of tattoos performed by non-medical practitioners are often overlooked. Limited information is available regarding the actual numbers of individuals getting tattoos and the perception regarding tattoos in the general population. @*Objective@#We investigated the prevalence of tattoos and public perception of tattoos. @*Methods@#Between August and September 2019, we performed a questionnaire survey that included 1,000 individuals aged ≥20 years. @*Results@#Among the 1,000 participants in this survey, 370 (37%) had received a tattoo; the number of participants with cosmetic tattoos (68.4%) was nearly 2-fold higher than the number of participants with body tattoos (31.6%). The most common motivation for getting a tattoo was “for beauty” (44.9%), followed by “convenience of make-up” (34.1%), and “recommendation from friends or others” (14.6%). In the tattoo-related satisfaction category, information regarding injected dye-induced adverse effects, facility hygiene, and pre-allergy testing were commonly rated as unsatisfactory by respondents. Only 322 (32.2%) participants were aware that semi-permanent tattoos could not be erased. Furthermore, 780 (78.0%) participants had a negative impression regarding body tattoos, and 844 (84.4%) participants preferred to get tattoos at specialized medical institutions based on the national regulations to minimize possible tattoo-induced adverse effects. @*Conclusion@#This study confirmed that a relatively large number of individuals had received tattoos but had a negative impression regarding this procedure. Educational and institutional management for public safety are necessary owing to a lack of awareness regarding tattoos and tattoo-related safety.

Survey on Perspectives and Treatment Status Regarding Skin Laser Treatment / 대한피부과학회지

BACKGROUND: Skin laser treatment has improved significantly and has become an effective treatment approach for many skin diseases while also having applications for beauty treatments. However, since skin laser transfers energy directly to the skin, the misuse of such treatment may result in permanent damage to skin tissues. OBJECTIVE: This survey of Korean adults, conducted to obtain their perspectives on and their treatment experience with skin laser treatment, will be used to determine the current status of skin laser treatment and to identify necessary changes to ensure proper and safe conduct of skin laser treatment. METHODS: From April 5th to April 12th, 2016, a survey was conducted to obtain information regarding the perspectives and the treatment experience of adults aged 20~59 years. RESULTS: Approximately 50% of the participants had experience with skin laser treatment, and among these, 24.7% had not received treatment at a dermatology clinic. Compared to treatment at a dermatology clinic, the danger of side effects was 1.7 times higher at a non-dermatology clinic, 2 times higher at a skin care shop, and 5.3 times higher at an Oriental medical clinic. Among patients who received skin laser treatment, 16.1% experienced side effects, and among these, 1 out of 4 patients visited a non-dermatologist for treatment of these side effects. CONCLUSION: The results of the survey showed that in order for the public to receive safe and effective skin laser treatment based on professional diagnosis, there is a definitive need to provide correct information to the public and to implement changes to ensure proper understanding of skin laser treatment among this population.

Conservative condylectomy alone for the correction of mandibular asymmetry caused by osteochondroma of the mandibular condyle: a report of five cases

We describe our experience with conservative condylectomy for the correction of facial asymmetry in five patients with osteochondroma of the mandibular condyle. All five patients presented with malocclusion and facial asymmetry, which are common clinical findings of osteochondroma involving the mandibular condyle. We performed conservative condylectomy without additional orthognathic surgery for all five patients, preserving the vertical height of the condylar process as much as possible. Following surgery, intermaxillary traction using a skeletal anchorage system with rubber elastics was performed on all patients to improve occlusion, and, when necessary, additional minimal orthodontic treatment was performed. The mean follow-up period was 42 months. At the last follow-up visit, all patients exhibited satisfactory facial symmetry and remodeling of the remaining condyle, with stable health and no signs of recurrence. In conclusion, conservative condylectomy alone, without subsequent orthognathic surgery, is adequate for the restoration of facial symmetry and the preservation of vertical condylar height in select patients with condylar osteochondroma.

Contralateral recurrence of necrotizing sialometaplasia of the hard palate after five months: a case report

Necrotizing sialometaplasia usually heals within 4 to 10 weeks with conservative treatment, and rarely recurs. When necrotizing sialometaplasia is present on the hard palate it may occur unilaterally or bilaterally. In this case, necrotizing ulceration occurred on the left hard palate of a 36-year-old woman after root canal treatment of the upper left first premolar under local anesthesia. After only saline irrigation the defect of the lesion completely healed and filled with soft tissue. After 5 months, however, a similar focal necrosis was found on the contralateral hard palate without any dental treatment having been performed on that side and progressed in similar fashion as the former lesion. We conducted an incisional biopsy and obtained a final pathological diagnosis for the palatal mass of necrotizing sialometaplasia. At the 3-year follow-up, the patient's oral mucosa of the hard palate was normal, without any signs and symptoms of the condition. We report a case of a second occurrence of necrotizing sialometaplasia on the contralateral side from the first, with a time lapse between the first and second occurrence.

The Use of Medical Devices for Medical Skin Care and the Legal Issues / 대한피부과학회지

BACKGROUND: Medical skin care is essential for the treatment of skin diseases all over the world. Medical skin care is also part of medical practice and this must be differentiated from the simple skin care that is given for normal healthy skin. OBJECTIVE: We wanted to discuss medical skin care and the related medical devices and legal issues. METHODS: We reviewed the related laws and regulations, we consulted experts and associations and we analyzed the result of the survey. RESULTS: Legally, medical skin care and simple skin care are well classified. However, many illegal procedures are still performed by non-medical personnel and many adverse effects have been reported as a result. Furthermore, there are no legal restrictions for the performer based on the grade of each medical skin care procedure. CONCLUSION: For the best results and safe procedures, medical skin care must be performed by approved medical equipment under the supervision of a physician or medical personnel. Continuous control and guidance by the government is strongly needed.

A Survey on the Mode of Working of Estheticians in OECD Member Nations andSome Asian Countries in Relation to Medical Service / 대한피부과학회지

In 2008, Korea has enacted new ordinances about the role of estheticians, but this law can be interpreted ambiguously, restricting hiring of estheticians in medical clinics. The purpose of the study is to obtain information about medical-esthetic systems in other countries. We have taken a survey of this object from 30 OECD & Asian countries, and the questionnaires returned from a total of 22 countries (Australia, Austria, Canada, Denmark, Finland, France, Germany, Hungary, Japan, Netherlands, New Zealand, Norway, Portugal, Slovak Republic, Spain, Switzerland, Turkey, United Kingdom, United States, Singapore, Israel, and Thailand), were used for the final analysis. The results are summarized as follows. In most countries, estheticians working independently deal with only healthy, normal skin. In most countries, estheticians working independently have no right to operate any medical instruments. In all 17 countries that returned the questionnaires medical clinics can employ estheticians, and only theses estheticians who belong to the medical clinics can handle the non-invasive medical instruments under the supervision of doctors. In 17 countries that have related legal regulations, nurses, under the control of doctors, can perform wider range of duties in various settings than estheticians. The survey concludes that the duties of estheticians are closely related with medical skin care services and estheticians can perform various non-invasive medical procedures only under the control of doctors. From consulting a variety of medical-esthetic systems in other countries, we propose that the estheticians be allowed to work in medical clinics to provide better medical services for the patients and to make more chances of employment for themselves.

Objective Non-invasive Assessment of Irritant Patch-test Reactions with Laser Doppler Perfusion Imaging (LDPI)

BACKGROUND: Traditional visual reading of patch-test reactions is a rather subjective method, lacking the sensitivity and reproducibility needed in experimental studies. Recently the laser Doppler perfusion imaging (LDPI) has been used to measure objectively the increase in superficial blood flow which results in the appearance of erythema. OBJECTIVE: We designed this study to examine the relationship between the LDPI measurement and visual reading after patch test to several different irritants. METHODS: In this study, reading of erythema in experimentally-induced irritant contact dermatitis was performed visually and by laser Doppler perfusion imaging (LDPI). In addition, we investigated whether the LDPI measurement was appropriate in the routine patch test clinic. RESULTS: A close correlation was shown between the 2 methods (r=0.9046, p<0.001) and the LDPI producing mean adjusted perfusion values (APVs) was able to discriminate between the different visual grades. CONCLUSION: LDPI is a valuable instrument to objectively assess intensity of irritant patch-test reaction, and is indeed one of the few methods which overcomes the inter-individual variations in visual reading, but this instrument is not appropriate to use routinely in patch test clinic because of unacceptably long measurement time.

A Case of Scrotal Calcinosis Associated with Pilar Cyst / 대한피부과학회지

Idiopathic calcinosis of the scrotum appears in childhood as multiple, asymptomatic nodules of the scrotal skin that gradually increase in size and number and sometimes discharge a chalky material. Histopathologic examination shows calcific deposits of various sizes that are present in the dermis and often surrounded by foreign body granulomatous inflammation. The pathologic mechanism of this condition is not clear, but there is accumulating evidence for dystrophic calcification of cyst rather than an idiopathic genesis. Here we present a 34-year-old otherwise healthy man who had a 10-year history of multiple, asymptomatic, firm, subcutaneous nodules of the scrotal skin, which sometimes discharged a chalky material. The nodules were completely excised and 45 nodules were observed in the histopathologic examination. In addition to the typical findings of idiopathic calcinosis of the scrotum, seven intact cysts were observed among 45 nodules. Among the seven cysts there were five pilar cysts and two indeterminate cysts with diffusely calcified keratinous content and attenuated walls. A mixture of calcified keratinous material and inflammatory infiltrates was detected. These findings suggest that idiopathic calcinosis of the scrotum may be deriven from the dystrophic calcification of cysts.

A Case of Kikuchi's Disease (Histiocytic Necrotizing Lymphadenitis) with Cutaneous Involvement Presenting As Aseptic Meningitis / 대한피부과학회지

Histiocytic necrotizing lymphadenitis, or Kikuchi's disease, is a benign self-limiting febrile illness usually affecting young women, which is manifested clinically by fever and cervical lymphadenopathy. Skin involvement in Kikuchi's disease is not frequent and Kikushi's disease presenting as aseptic meningitis is rare, with only three previous reports in English literature to date. We present a 16-year-old girl with cervical lymphadenopathy and fever who was diagnosed with Kikuchi's disease, suffering from multiple transient erythematous maculopapular skin lesions and presenting as aseptic meningitis.

A Case of Gianotti-Crosti Syndrome Associated with Epstein-Barr Virus Infection / 대한피부과학회지

Gianotti-Crosti syndrome(GCS) is a distinct exanthematic, acrolocated eruption of childhood caused by a variety of infectious agents. Historically hepatitis B antigen positive(HBsAG+) papular acrodermatitis of childhood and HBsAg negative(HBsAg-) papulovesicular acrolocated syndrome have been distinguished. Here we present a 22-month-old female patient who developed eruptions typical for GCS and showed serologic evidence of an acute Epstein-Barr virus(EBV) infection. Serologic investigations revealed no evidence of recent infection with most common viruses except EBV infection. This case suggests that EBV infection should be sought in cases of GCS which cannot be related to HBV infection.

Ultrastructural Study of Vitiligo

BACKGROUND: There is a long-standing controversy whether melanocytes in vitiligo of more than 1 year duration are actually lost or still present. Resolving this matter is essential in understanding the underlying pathology and for the development of the treatment. On previous immunohistochemical and ultrastructural studies of vitiligo lesions, damage of melanocyte and keratinocyte in early lesions were reported and complete absence of melanocyte in long standing lesions were known. OBJECTIVE: This study aimed to determine the existence of the differences in pathologic changes in melanocytes according to the duration of the lesion. METHODS: We investigated the vitiliginous skin samples from 31 patients with early(less than 1 year duration) vitiligo and 30 patients with long standing(l to 5 years duration) vitiligo under the electron microscopy. RESULTS: Multiple degenerative changes in melanocytes were observed in the early and long standing lesions. In long standing lesions, degeneration of melanocytes including pyknotic, in-dented nuclei, vacuolated cytoplasms and blunted dendrites were more pronounced than early lesions. Even in long standing lesions, definite or presumptive melanocytes were observed in 16(53.3%) of 30 cases. CONCLUSION: Our results suggest that the melanocytes of vitiligo lesions were damaged and that the percentage of degenerative changes increase in accordance with the duration of the lesion. However, in long standing lesions as well as in early lesions, some residual melanocytes can be observed ultrastructurally.

Two Cases of Cutaneous Metastases Originating from Esophageal Carcinoma / 대한피부과학회지

We report two cases of cutaneous metastases originating from esophageal carcinoma. Case 1, about 0.5cm sized brownish round keratotic papule was detected 1 month ago on the left fifth finger tip in a 70-year-old man. Case 2, about 1.5 x 1.2cm sized ivory oval flat topped elevated nodule was detected 1 month ago on the lower lip in a 60-year-old man. Histologic examination of case 1 showed that dilated lymphatics contained tumor nests, some of which showed central necrosis. Case 2 showed tumor cell infiltration from upper dermis to mid dermis. Regardless of chemotherapy, both patients died after two and three months from the appearance of cutaneous lesions respectively.

Bath-8-MOP-UVA Therapy for Psoriasis / 대한피부과학회지

BACKGROUND: An alternative approach to oral PUVA therapy for psoriasis, psoralen bath plus UVA therapy(bath PUVA therapy) that avoids the adverse effects associated with oral PUVA therapy has increasingly been used during recent years. OBJECTIVE: This study was performed to evaluate the efficacy and safety of bath-8-MOP-UVA therapy in the treatment of psoriasis. METHODS: Twenty patients were enrolled in this study after determination of the minimal phototoxic doses(MPD). We evaluated the total treatment number, duration, final UVA dose and total cumulative UVA dose of bath-8-MOP-UVA therapy to reach grade 4 response and categorized each patient into clearing, improvement, or failure groups based on the therapeutic efficacy. We measured the PASI score at two week intervals. Blood samples were obtained from all twenty patients 2 hours after bath-8-MOP and plasma levels of 8-MOP were quantified by a reverse phase high performance liquid chromatography. RESULTS: The following results were obtained from this study. 1. Phototoxicity testing with bath-8-MOP-UVA elicited mean MPD value of 3.5+/-1.3J/cm2. 2. The mean PASI score at 10 weeks was significantly decreased to 5.8+/-1.3 from baseline PASI score 20.1+/-4.3. 3. Among 20 patients, clearing was shown in 13 patients(65%), 6 patients(30%) were improved and 1 patients(5%) showed failure. 4. In clearing and improvement groups, the mean treatment number, duration, final dose of UVA and total cumulative UVA dose reaching grade 4 were 19.3+/-5.4, 49.9+/-13.5days, 5.2+/-1.3J/cm2 and 68.6+/-30.1J/cm2, respectively. 5. Five patients experienced side-effects. Two patients had intense tan, one withdrawing because of it and the other continued treatment. Three had pruritus that was controlled on oral antihistamines. Phototoxic or other classic adverse effects of oral PUVA therapy, such as nausea, vomiting and headaches, were not observed in any of our 20 patients. 6. All twenty patients had an undetectable plasma 8-MOP level. The lower limit of detection level was 20ng/ml. CONCLUSION: Bath-8-MOP-UVA therapy for psoriasis is a very effective and safe alternative to oral PUVA therapy.

A Case of Milia en Plaque Occurring on the Bilateral Retroauricular Area and Occipital Scalp / 대한피부과학회지

Milia en plaque(MEP) is an unusual eruption characterized by multiple milia-like lesions within an erythematous edematous plaque in the retroauricular area. The histopathological findings are consistent with milia. We report a case of MEP occurring on the bilateral retroauricular area and occipital scalp. To our knowledge, a case which has developed on the scalp has not been reported previously. The absence of a known etiologic factor in contrast to the previously published causes suggests that the present case belongs to the group of primary milia.

One Case of Displacement of Copper - T IUD into Urinary Bladder / 대한산부인과학회잡지

Uterine perforation is a serious complication in users of intrauterine devices for contraception. Authors encountered one case of displacement of Copper-T IVD into urinary blpossibly due to uterine perforation on insertion of the Copper-T IUD in a 28 year old 1-multipara, who experienced normal intrauterine pregnancy in the circumstances. This patient was in silent, asymptomatic condition and underwent cesarean section. And Copper-T IUD was removed under the cystotomy. So we report one case with brief review of literatures
