In order to improve jab satisfaction of living rehabilitation teachers and welfare of the disabled, we need national-wide support and legal system for the disabled and living rehabilitation teachers.

불안정성 경추손상 환자에서의 Halifax Interlaminar Clamps를 이용한 후방고정술 : 추척조사 결과 Follow-up Study

유대진,양의중,장석정 대한신경외과학회 1993 Journal of Korean neurosurgical society Vol.22 No.1

The most common severe cervical spine injury involving the posterior elements is subluxation or dislocation in which the posterior ligamentus complex is completely tom. Late instability is more common than previously realized, because ligamentous structures do not reconstitute normally, even with prolonged external rigid fixation. Subluxation of the cervical vertebrae in a flexion injury can be reduced by skeletal traction ; however, they usually require posterior stabilization. Unilateral and bilateral facet dislocation freqently require open reduction and posterior stabilization. The authors have used interlaminar clamps for the stabilization of thirty cases of unstable cervical spine. Advantages of this method are 1) immediate and rigid stabilization without cord injury. 2) early ambulation and prevention of respiratory complication and pressure sore. And also, posterior cervical stabilization with Halifax clamps is an easier, safer and faster technology in treatment of unstable spine.

Recently, the artificial intelligence(AI) is used in various environments in life, and research on this is being actively conducted in education. In this paper, we designed a Design-Based Research(DBR)-based AI programming education program and analyzed the application of the program for the improvement of understanding of AI in elementary school. In the artificial intelligence education program in elementary school, we should considerthat itshould be used in conjunction with software education through programming activities, rather than creating interest through simple AI experiences. The designed education program reflects the collaborative problem-solving procedures following the DBR process of analysis - design - execution - redesign, allowing the real-world problem-solving activities using AI experiences and block-type programming language. This paper also examined the examples of education programs to improve understanding of AI by using Machine Learning for Kids and to draw implications for developing and operating such a program.

Late Onset Foreign Body Reaction due to Poly-L-Lactic Acid Facial Injections for Cosmetic Purpose

( Yu Jin Jeon ),( Dae Won Koo ),( Joong Sun Lee ) 대한피부과학회 2020 Annals of Dermatology Vol.32 No.6

The safety and efficacy of Poly-L-lactic acid (PLLA) as an injectable facial volumizer for the treatment of lipoatrophy and facial rejuvenation has been widely proven. We experienced a remarkable case of deep-seated nodules on both the cheeks of 57-year-old female 18-months after administration of PLLA filler injection for cosmetic purpose and performed a skin biopsy. With hematoxylin and eosin stain, the nodule showed non-caseating granulomas consisting of histiocytes with central foreign bodies in the dermis. This case report represents the late-onset foreign body reaction due to PLLA facial injections. (Ann Dermatol 32(6) 519∼522, 2020)

( Yu Ri Woo ),( Dong Ha Kim ),( Jae Hwa Kim ),( Young Min Cho ),( Kyung Eun Jung ),( Dae Won Koo ),( Joong Sun Lee ) 대한피부과학회 2015 대한피부과학회 학술발표대회집 Vol.67 No.1

Erythromelanosis follicularis faciei et colli (EFFC) is characterized by hyperpigmentation, erythema and follicular papules on the face with male predominance. Becker’s nevus is a hamartoma with unilateral brownish hyperpigmentation, commonly with hypertrichosis. These lesions are frequently localized to the upper extremities and trunk. The lesions mostly occur during adolescence and are more common in males than females. An 18-year-old Korean man presented with 6-year history of asymptomatic brownish pigmented patches on his left side of the preauricular and mandibular area. During puberty, hair developed on the hyperpigmented patch. The patient was also complained of having flesh colored papules on both his mandibular areas for 13 years. Physical examination revealed the follicular keratotic papules on both side of the preauricular and mandibular areas and reddish-brown pigmented hairy patches on his left side of the lesion. The histopathological examination of the left side of the lesion revealed the follicular plugging, mild acanthosis, elongated rete ridges with flat bottoms and hyperpigmentation of the basal layer of epidermis. It was diagnosed as having EFFC colocalized with Becker``s nevus based on the clinical and histopathological findings. There are, to our knowledge, no previous reports of Becker’s nevus in the lesional skin of EFFC. We think it would be interesting to report this case for its rare clinical manifestation.

Background: Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease with high mortality in East Asia. This study aimed to develop, for primary care providers, a prediction score using initial symptoms and basic laboratory blood tests to differentiate between SFTS and other endemic zoonoses in Korea. Methods: Patients aged ≥ 18 years diagnosed with endemic zoonoses during a 3-year period (between January 2015 and December 2017) were retrospectively enrolled from 4 tertiary university hospitals. A prediction score was built based on multivariate logistic regression analyses. Results: Of 84 patients, 35 with SFTS and 49 with other endemic zoonoses were enrolled. In multivariate logistic regression analysis, independent predictors of SFTS included neurologic symptoms (odds ratio [OR], 12.915; 95% confidence interval [CI], 2.173–76.747), diarrhea (OR, 10.306; 95% CI, 1.588–66.895), leukopenia (< 4,000/mm3 ) (OR, 19.400; 95% CI, 3.290– 114.408), and normal C-reactive protein (< 0.5 mg/dL) (OR, 24.739; 95% CI, 1.812–337.742). We set up a prediction score by assigning one point to each of these four predictors. A score of ≥ 2 had 82.9% sensitivity (95% CI, 71.7%–87.5%) and 95.9% specificity (95% CI, 88.0%–99.2%). The area under the curve of the clinical prediction score was 0.950 (95% CI, 0.903–0.997). Conclusion: This study finding suggests a simple and useful scoring system to predict SFTS in patients with endemic zoonoses. We expect this strategic approach to facilitate early differentiation of SFTS from other endemic zoonoses, especially by primary care providers, and to improve the clinical outcomes.

Deep fungal infection related to hydrophyte

Deep fungal infection, or mycoses of implantation, is infections caused by fungi that have been introduced directly into the dermis or subcutaneous tissue through a penetrating injury. Here, we present deep fungal infection which occurred after the contact with hydrophyte. A 58-year-old man presented with tender purpuric plaques and nodules involving both leg of 2 months in duration. He had a history of contact with hydrophyte on the lower leg during fishing few days before the skin lesion. Histopathologic examination of the lesion on the right leg revealed suppurative granulomatous inflammation with round GMS-positive fungal spores in the deep dermis to subcutaneous area. Skin lesion was gradually improved with antifungal agents (itraconazole) and the symptom has been maintained well with the treatment for 4 months. With growing interest in leisure recently, the incidence of uncommon disease is increasing. Fishing can increase not only the disease caused by the fish, but also the change of contact with hydrophyte and the likelihood of the associated cutaneous diseases. Fungal infection including protothecosis may occur in contact with hydrophyte. Thus, although it is rare, dermatologists should be aware that deep fungal infection caused by the hydrophte may occur during outdoor activity with favorable outcome with antifungal agent and perform biopsy to evaluate other suspected diseases.

Human papillomavirus 16-related Bowen’s disease on nail apparatus

( Dae Young Oh ),( Ji Seon Kim ),( Hyun Yi Lee ),( Yu Jin Jeon ),( Dae Won Koo ),( Joong Sun Lee ) 대한피부과학회 2019 대한피부과학회 학술발표대회집 Vol.71 No.1

Bowen’s disease is a common cutaneous malignancy, regardless of race. Various causes of Bowen’s disease include solar damage, arsenic, immunosuppression and viral infection. A 15-year-old woman presented with mild tender, verrucous plaque involving proximal to lateral nail fold of both great finger of 4 years in duration. The lesion began to increase in size 1 year ago. Histopathologic examination of the lesion on the nail fold revealed mild to moderate dysplasia of squamous epithelium with perinuclear haloes; suggesting Bowen’s disease related to viral infection. HPV 16 positivity appeared in the HPV PCR test. Skin lesion was gradually improved with 2 times of cryosurgery and HPV vaccine injection (Gardasil®). HPV 16 has been known as a mucosal oncogenic HPV, and the virus is regarded as a high-risk factor in the development of cervical cancer. A few cases of HPV 16-related Bowen’s disease on the hand and were reported. However, only 3 cases of HPV 16-related Bowen’s disease on nail apparatus were reported. Bowen’s disease of the nail apparatus differs from that of the skin. Unfortunately, carcinogenic role of HPV 16 in human cutaneous keratinocyte has yet to be elucidated. Thus, although it is rare, dermatologists should be aware that HPV 16-related Bowen’s disease may occur on the periungal area with favorable outcome with cryosurgery and HPV vaccine and perform biopsy with HPV PCR to evaluate other suspected diseases.

Fibrous hamartoma of infancy with eccrine gland hyperplasia

( Yu Ri Woo ),( Jae Hwa Kim ),( Dong Ha Kim ),( Young Min Cho ),( Kyung Eun Jung ),( Dae Won Koo ),( Joong Sun Lee ) 대한피부과학회 2015 대한피부과학회 학술발표대회집 Vol.67 No.1

Fibrous hamartoma of infancy is a rare benign mesenchymal tumor which usually occurs in the first 2 years of life. Fibrous hamartoma of infancy is microscopically composed of three components: (1) trabeculae composed of fibrous tissue; (2) primitivemesenchyme; and (3) mature adipose tissue. The distinctive triphasic histologic features of the fibrous hamartoma are important for diagnosis. An 1-year-old Korean female infant presented with nontender, solitary, firm grayish nodule on the left side of the lower back. Multiple coarse hairs were present on the surface of the nodule. The punch biopsy was performed from a nodule. Histopathologic examination of the lesion revealed the foci of fibrous trabeculae, myxoid mesenchymal tissue, and mature adipose tissue, which were arranged in an organoid pattern. These histologic findings were characteristic of fibrous hamartoma of infancy. In addition, hyperplasia of eccrine glands were present within the lesion. The present case demonstrates the fibrous hamartoma of infancy with the addition of changes in eccrine glands, which have rarely been reported in the previous cases. We experience a case of fibrous hamartoma of infancy with eccrine gland hyperplasia and suggest that this could be used as an auxillary feature at diagnosing the fibrous hamartoma of infancy.
