  • Skin lesions are common diseases that range from skin rashes to skin cancer, which can lead to death. Note that early diagnosis of skin diseases can be important because early diagnosis of skin diseases considerably can reduce the course of treatment and the harmful effect of the disease. Recently, the development of computer-aided diagnosis (CAD) systems based on artificial intelligence has been actively made for the early diagnosis of skin diseases. In a typical CAD system, the accurate classification of skin lesion types is of great importance for improving the diagnosis performance. Motivated by this, we propose a novel deep ensemble classification with multi-scale attention networks. The proposed deep ensemble networks are jointly trained using a single loss function in an end-to-end manner. In addition, the proposed deep ensemble network is equipped with a multi-scale attention mechanism and segmentation information of the original skin input image, which improves the classification performance. To demonstrate our method, the publicly available human skin disease dataset (HAM 10000) and the private animal skin lesion dataset were used for the evaluation. Experiment results showed that the proposed methods can achieve 97.8% and 81% accuracy on each HAM10000 and animal skin lesion dataset. This research work would be useful for developing a more reliable CAD system which helps doctors early diagnose skin diseases.

  • Skin and joint diseases are relatively common in dogs. Nutritional complementation is one of the various management strategies for these disorders. This study evaluated the safety and clinical efficacy of Kyungokgo-gamibang in dogs with skin and joint diseases. Thirty dogs with diseases were included and divided into three groups: control group (n = 15), skin group (n = 10), and joint group (n = 5). The skin and joint groups were fed skin and joint gums composed of Kyungokgo-gamibang extract with standard treatment for four weeks. The control group included dogs with skin diseases who were administered standard skin infection treatment for 4 weeks. The physical and laboratory results showed no remarkable adverse effects of Kyungokgo-gamibang extract after its administration in dogs. Clinical efficacy was evaluated using quality of life scale, and levels of cytokines, including interferon-γ, interleukin (IL)-2, IL-6, IL-8, IL-10, monocyte chemoattractant protein-1, and tumor necrosis factor-α, for 4 weeks in all groups. Dermatologic clinical scales were performed for 4 weeks in the control and skin groups. Both the control and skin groups had significantly decreased dermatologic clinical scales, including pruritus and erythema scales (p < 0.05). Among the cytokine levels, only IL-2 concentration was significantly decreased in the skin group after 4 weeks of administration of the Kyungokgo-gamibang extract (p = 0.032). There was no significant difference between the levels of cytokines on days 0 and 28 in the joint group. The quality of life scale was significantly increased after week 4 compared to week 0 in the skin (p = 0.008) and joint groups (p = 0.041). This study suggests that Kyungokgo-gamibang extract can be applied in managing dogs affected by skin and joint diseases without adverse effects.

  • Kikuchi병은 주로 젊은 여성에서 호발하고 소아에서는 비교적 드문 질환으로 원인 및 발생기전은 자세히 알려진 바 없으나 특별한 치료 없이도 수개월 이내에 자연적으로 회복되는 양성질환이다. 진단은 침범된 림프절의 특징적인 병리조직학적 소견을 확인하면 가능하다. 대부분의 환자에서 임상증상으로 림프절 비대와, 발열이 나타나고 피부증상은 16-40%에서 동반되며 주로 안면부, 상지, 상부 체간에 발생하고 대부분 작은 반점, 구진, 드물게 판과 결절 형태로 나타난다. 국내에서는 1983년 아급성 괴사성 임파선염이라는 이름으로 처음 언급한 이래 드물지 않게 보고되어왔으나 기존의 보고들은 피부증상을 동반하지 않거나 얼굴과 상지에 국한된 피부병변을 가진 증례 보고가 대부분이었다. 저자들은 지속적인 발열과 우측 경부 림프절 비대를 주소로 내원한 9세 남아에서 림프절의 조직검사결과 Kikuchi병을 진단할 수 있었고 이후 하지를 포함한 전신에 반점과 구진형태의 홍반성 병변이 발생한 Kikuchi병 1례를 경험하였기에 문헌고찰과 함께 보고하는 바이다.

  • Implantation of allografts has increased widely with not only the availability of many allogenic bone but also allogenic soft tissues. The aim of tissue banking is to provide surgeons with safe tissues compatible with their intended clinical application. The incidence of tissue transplant-transmitted infection is unknown and can only be inferred from prospective studies. The possibility of donor-to-recipient disease transmission through soft tissue transplantation can be considered by reviewing the risk associated with other transplanted hard tissues. Viral, bacterial, and fungal infections have been transmitted via transplantation of soft tissue allografts such as skin, cornea, dura, pericardium. fascia lata, and heart valves. Corneas have transmitted rabies, Creutzfeldt-Jakob disease (CJD), hepatitis B (HBV), cytomegalovirus (CMV), herpes simplex virus (HSV), bacteria, and fungi. Heart valves have been implicated in transmitting tuberculosis, hepatitis B. HIV-1 and CMV. CJD has been transmitted by dura and pericardium transplants. Skin has transmitted CMV, bacteria, and fungi. Cadaveric skin, pericardium, dura, and fascia lata have been used in dental patients with intra-oral soft tissue injuries and GBR. This study is review of the considering transmission of infectious disease in allogenic soft tissues and guidelines of reducing the risk. Prior to use, many tissues are exposed to antibiotics, disinfectants, and sterilants, which further reduce or remove the risk of transmitted disease. Because some soft tissue grafts cannot be subjected to sterilization steps, the risk of infectious disease transmission remains and thorough donor screening and testing is especially important.

  • Acquired cutis laxa is a rare disease. Owing to few reports on the condition, no statistical data have been produced. Cutis laxa is characterized by drooping skin, caused by decreased levels of dermal elastin, leading to reduced skin elasticity. The disease usually emerges on the neck or trunk and spreads throughout the body; however, it rarely involves the extremities. Moreover, cases localized to the face are rare. The objective of this clinical case report was to highlight this unusual disease in a 24-year-old female, with localization on the face and neck. The patient underwent surgery for treatment of bilateral ear lobe and eyelid skin laxity.

  • Objective : Skin barrier protects skin against harmful environment. Its function includes antimicrobial barrier as well as physical barrier. But there are few studies about skin barrier function about men and women who don't have skin disease. The aim of this study is to investigate skin barrier function healthy men and women show. Method : There are many ways to measure skin barrier function, but lately transepidermal water loss is mainly used to know skin barrier function. Transepidermal water loss was measured over eight four the Korean twenties and thirties who don't have skin disease from March 14th, 2007 to March 16th 2007. We surveyed cubital fossa and cheek beside nose to measure transepidermal water loss and used vapometer. Result : After analyzed data, we concluded that cheek showed higher transepidermal water loss than cuital fossa. At cheek, the thirties had higher transepidermal water loss than the twenties. The male got higher transepidermal water loss than the female at cheek and in the average. And temperature and humidity effected on transepidermal water loss. Conclusion: In our study, it was observed that temperature and humidity effected on transepidermal water loss. In traditional korean medicine, the inbalance of cold(寒), heat(熱), dryness(燥), wetness(濕) makes many diseases and the inbalance of them induces dameum(痰飮) and the disorder of blood flow. Dameum(痰飮) and the disorder of blood flow make skin diseases made by abnormal skin barrier function in many ways. So we need to study dameum(痰飮) and the disorder of blood flow to take care of patients who have abnormal skin barrier function.
