Fungal Melanonychia Caused by Cladosporium Species: A Case Report

윤지하,안민균,박은주,김광호,김광중 대한의진균학회 2019 대한의진균학회지 Vol.24 No.3

Fungal melanonychia is typically associated with onychomycosis and is known to be a relatively uncommon nail disorder. The known pathogens causing fungal melanonychia include both dematiaceous and non-dematiaceous fungi. Here we describe the case of a 60-year-old man with a 1-year history of nail discoloration in both index fingers. The possibility of subungual neoplasm was excluded by histological examination. Subsequent mycological examination revealed the presence of Cladosporium species in the lesion. The patient was successfully treated with oral itraconazole.

보르헤스와 미셸 푸코의 역사관 비교

윤지하 한국외국어대학교 중남미연구소 2000 중남미연구 Vol.19 No.2

푸코와 보르헤스는 언뜻 보기에 별다른 연관성이 없어 보인다. 보르헤스는 권력의 이동과 지식과의 연계라는 푸코의 중심문제에 대한 관심을 직접적으로 언급한 적이 없으며, 푸코 역시도 보르헤스의 픽션으로서의 글쓰기에 관심을 피력한 적이 없었기 때문이다. 그러나 보르헤스가 서구사상에 미친 크고 작은 영향력은 재론의 여지가 없는데, 이렇게 전혀 관계없이 보이는 푸코는 자신의 저서 『말과 사물』에서 보르헤스로부터 얻은 영감을 직접적으로 표출했다. 그가 도취되었던, 전혀 새로운 사고체계에 대한 매력으로 이 저서를 쓰게 되었다는 것이다. 푸코가 관심을 가졌던 분야는 인문과학에서 사회과학에 이르기까지 다양한 것인데, 그는 저서의 제목이나 부제에서 '역사'라는 단어를 직접, 간접적으로 사용했다. 그러나 그의 역사는 기존의 단선적 기술방식을 사용하여 각 시대 간의 연속과 인과관계를 밝히는 것에 주목했던 역사의 개념과는 다른 것이다. 이로부터 보르헤스가 시작한 기존 사고체계에 대한 거부와 전복, 더 나아가 하나의 시각이 아닌 다양한 시각에 의해 재구성될 수 있는 포스트모더니즘적 역사관을 발견할 수 있다. 푸코가 고고학적 방법과 계보학적 방법을 통해 각각 역사를 재구성하고 주변부의 역사를 중심으로 부각시킨 것은 보르헤스가 그의 작품에 형상화했던 역사적 관점과 일치하는 것이다.

보르헤스와 정치

윤지하 한국외국어대학교 중남미연구소 2000 중남미연구 Vol.19 No.1

정치와 문학의 관계를 논할 수 있는 것은 비단 사회적인 내용을 담는 문학작품에만 국한되는 것은 아니며 때로는 가장 비정치적인 작품이 정치적으로 해석될 수 있는 가능성 역시도 열려있는 것이다. 20세기 문학을 새로이 정립한 보르헤스 역시도 정치와 무관했던 작가로 재단할 수는 없는데 보르헤스는 현실과 환상 사이에 존재하는 세계를 창조하는 가운데, 그 속에 자신이 바라본 세계에 대한 인식과 구현될 수 있는 정치적 질서를 검토해 나간 것이다. 물론 보르헤스는 작품 전체에 있어서 정치적 색채를 빈번히 드러낸 작가는 아니었다. 그럼에도 불구하고 당시 세계를 지배했던 다양한 흐름을 직접, 간접적으로 경험하고 가문의 역사를 들으면서, 그리고 자신의 기억 속에 남아 있는 과거 조국에 대한 향수를 간직하면서 나름대로의 정치적 시각을 구축했음은 부정할 수 없는 사실이다. 또한 보르헤스가 삶 속에서 보여주었던 단편적인 정치적 활동들이 이러한 사실을 증명해 준다. 작가로서 보르헤스가 표출하고자 했던 정치적인 시각은 다음과 같이 요약할 수 있다. 청년기 시인으로서의 활동에는 민족주의와 아방가르드적 흐름이, 중년기 세계적 명성을 얻은 시기에는 무정부주의적 성향이, 그리고 노년기로 접어들면서 상대주의적이고 통합주의적인 태도가 그의 작품에서 발견되는 것이다.

목에 발생한 피부 혈관평활근종 1예

A 31-year-old Korean man presented with a 6-month history of a painful nodule on his neck. Excisional biopsy was performed for diagnosis and treatment. Histopathological evaluation of the resected specimen revealed well-demarcated vascular proliferation with adipose tissue in the dermis, and the patient was diagnosed with cutaneous angioleiomyoma with fat modulation. To our knowledge, angioleiomyomas most commonly occur on the extremities, and the head and neck are rarely involved. Few cases of cutaneous angioleiomyomas of the neck have been reported in the literature. We report a rare case of cutaneous angioleiomyoma of the neck. (Korean J Dermatol 2021;59(1):61∼63)

A Suspected Case of Hyperkeratotic Head and Neck Malassezia Dermatosis Presenting with Acanthosis Nigricans

안민균,윤지하,조은별,박은주,김광호 대한의진균학회 2018 대한의진균학회지 Vol.23 No.4

A 19-year-old woman presented with an asymptomatic cutaneous discoloration on her nape. Dermatological examination revealed localized dark brown to dark pigmented velvety macules and patches. She denied a past medical history, except for a 7-kg weight gain over a 6-months period. Histopathologically, the specimen showed hyperkeratosis, epidermal hyperplasia, mild acanthosis, and papillomatosis. In addition, keratin material and fungal spore were noted between the papilloma ridges. Periodic acid-Schiff special stain showed a positive result for the fungal spore in the horny layer. She was treated with a daily oral dose of terbinafine and topical flutrimazole. After 12 weeks of treatment, she is currently under observation without pigmentation and adverse effect. We considered the initial diagnosis as acanthosis nigricans because of weight gain, similar clinical features, and histological findings. However, the final diagnosis was hyperkeratotic head and neck Malassezia dermatosis considering the presence of yeast and the dramatic improvement after antifungal treatment. To the best of our knowledge, hyperkeratotic head and neck Malassezia dermatosis is not well characterized in the literature. It is an unusual variant of pityriasis versicolor. The skin lesion appears brown to dark, scaly, and hyperkeratotic macules and patches located on the face and neck. Here, we reported an unusual case of hyperkeratotic head and neck Malassezia dermatosis.

Onychomycosis Coinfected with Pseudomonas aeruginosa: Report of Four Cases

장예지,윤지하,박은주,김광중,김광호 대한의진균학회 2019 대한의진균학회지 Vol.24 No.4

Patients presenting with green nail syndrome often show coinfection with fungus. A delay in the accurate diagnosis of coinfection may warrant longer treatment duration. Four patients with green nail syndrome coinfected with fungus were reviewed retrospectively. Fungal culture, cultivating Candida parapsilosis and Candida albicans, was performed in two patients' samples. The mean time of the initiation of treatment for onychomycosis after the first visit was 5.75 weeks. If green nail syndrome is suspected, screening for fungal coinfections and precise management are necessary.

Impacts of Return-to-Work Type and Period on Job Retention in Workers with Occupational Injuries and Diseases

정인철,박재범,김형렬,윤지하,원종욱,노재훈 대한의학회 2018 Journal of Korean medical science Vol.33 No.1

Background: Despite the necessity of job retention in achieving return-to-work (RTW) goals, many workers leave their jobs after returning to work. The objective of this study was to examine the impacts of RTW type and period on job retention in Korean workers with occupational injuries and diseases. Methods: Data were derived from the Panel Study of Worker's Compensation Insurance, including data from 2,000 systemically sampled workers who had finished recuperation in 2012; three waves of survey data were included in the analyses. Workers who returned to work (n = 1,610) were included in the analysis of the relationship between RTW type and job retention, and 664 workers who returned to their original workplaces were included in the analysis of the relationship between RTW period and job retention. The participants completed a questionnaire, and administrative data were provided by workers' compensation insurance. Results: A Cox proportional-hazards regression analysis showed an increased hazard ratio (HR) for non-retention of 2.66 (95% confidence interval, 2.11–3.35) in reemployed workers compared to that in workers returning to their original workplaces. Among workers returning to their original workplaces, HRs for non-retention were increased in workers with a RTW period of 13–24 months (3.03 [1.52–6.04]) and > 24 months (5.33 [2.14–13.25]) compared to workers with a RTW period of ≤ 3 months. Conclusion: RTW type and period were significantly related to job retention, suggesting that policies for promoting job retention rate should be implemented.

신경섬유종증 1형 가족력이 있는 환자에서 발생한 양성 두부 조직구증 1예

정준우 ( Joon Woo Jung ),윤지하 ( Ji Ha Yoon ),박은주 ( Eun Joo Park ),김광중 ( Kwang Joong Kim ),김광호 ( Kwang Ho Kim ) 대한피부과학회 2021 大韓皮膚科學會誌 Vol.59 No.1

Benign cephalic histiocytosis is a rare subtype of non-Langerhans cell histiocytosis of unknown etiology. It usually occurs in infants and children and resolves spontaneously. A 14-month-old infant presented with multiple papules on his face, trunk, as well as upper and lower extremities. Histopathological examination of a biopsy specimen showed diffuse proliferation of histiocytes in the dermis with scattered lymphocytes and eosinophils. Immunohistochemical evaluation showed cells that were immunonegative for S-100 and CD1a but strongly immunopositive for CD68. Benign cephalic histiocytosis usually affects the head and neck areas and rarely spreads to other sites. Some reports in the available literature have described an association between juvenile xanthogranuloma and neurofibromatosis type 1; however, the association, if any, between benign cephalic histiocytosis and neurofibromatosis type 1 is unclear. We report a rare case of benign cephalic histiocytosis in a patient with a family history of neurofibromatosis type 1. (Korean J Dermatol 2021;59(1):58∼60)
