  • Staphylococcus aureus is a major pathogen that causes clinical infections in humans and can also cause massively colonized in lesion skin, particularly in atopic dermatitis patients. This study investigated the effects of photodynamic inactivation with radachlorin and diode laser irradiation on the viability of S. aureus in vitro and assessed the effects of the dose of laser transmission. In the PDI group, 5 𝜇L of S. aureus suspension and 5 𝜇L of radachlorin were inoculated in a 55 mm petri dish (63.6 cm2). The samples were placed in a 37° incubator for 30 min and then irradiated with light (660 nm diode laser). After laser irradiation, the cells were stored for 24 h at 37° in an incubator with 5% CO2, and the number of colonies was counted. All CFU/mL of S. aureus were reduced by diode laser in the presence of radachlorin, with a killing rate of 87.9% at an energy dose of 9 J/cm2. This study contribute to treat colonized with S. aureus in atopic dermatitis patients and wound infections by providing information on the optimal dose of laser transmission using PDI to eliminate S. aureus.

  • Extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT lymphoma) is a low-grade B-cell lymphoma that typically follows an indolent clinical course. It occurs in a variety of mucosal linings extranodal tissue, most commonly in the stomach. Other commonly involved sites include other parts of the gastrointestinal tract, thyroid, salivary gland, lung, lacrimal gland, synovium, dura mater, breast, skin, and eyes. It occurs very rarely in the buccal mucosa. A 50-year-old man came to the clinic while presenting a 5-month history of right-sided buccal mass. The incisional biopsy did not confirm the diagnosis of the lesion. He underwent complete excision of buccal mass for the diagnosis and treatment. The final pathology confirmed MALT lymphoma immunohistochemically. After surgery, he received radiotherapy with 30.6 Gy. There is no recurrence for 8 months after treatment. Herein we report a rare case of buccal MALT lymphoma with a review of the literature.

  • Although warts are a common skin condition/disease that recurs in childhood, treatment completion is difficult owing to the pain associated with conventional therapies. In this case, Korean herbal medicine, Guijakjihwang-Tang, and indirect moxibustion was used to treat a recalcitrant cutaneous wart without pain and recurrence. A 7-year-old boy presented with recurrent cutaneous warts on his right hand and received cryotherapy 3 times in the previous year. The wart recurred during the course of cryotherapy treatment, and the patient did not want to suffer any more pain from the previous treatment. Therefore, parents sought an efficient and painless therapy. The patient was treated for 2 months using Guijakjihwang-Tang combined with indirect moxibustion. The prominent lesion separated in the 2nd month of treatment and completely recovered without adverse events in the 3rd month. There was no recurrence over 12 months of follow-up. This report provides meaningful insights into the use of Korean medicine as a safe, painless and efficient treatment for warts in pediatric patients.

  • Penile Mondor disease (MD) is a palpable, painful, subcutaneous induration caused by superficial dorsal penile vein thrombosis. We report a case of penile MD that was suspected to be related to prolonged oral sildenafil use. A 46-year-old man visited our emergency department with sustained penile pain and swelling that began 7 hours after sexual intercourse. He had used oral sildenafil intermittently for 11 years and engaged in sexual intercourse the previous night after taking sildenafil. Examination revealed no evidence of intercourse-related trauma to the genital area or an increase in penile skin temperature. However, penile swelling and tenderness over the protruding dorsal penile vein were noted. A color Doppler ultrasound examination was performed immediately, which showed hyperechoic thrombosis in the right superficial dorsal penile vein that was dilated, with soft tissue swelling and no detectable flow signal in the thrombotic lesion. The patient was diagnosed as having penile MD. The patient was treated conservatively. Some reports have indicated the involvement of sildenafil in thrombogenesis. Physicians should be aware that prolonged oral sildenafil use may be associated with penile MD.

  • Objectives: The purpose of this study is to report the effect of Korean medicine treatment in a patient with Herpes Zoster (HZ) during pregnancy. Methods: During 12 days of hospitalization, a patient was treated by Korean medicine treatment such as herbal medicine including Gami-danggui-san, acupuncture, cupping and fumigation. To evaluate the effect of treatment, we took pictures of skin lesion and symptoms were measured by Numeric Rating Scale (NRS), Short-Form McGill Pain Questionnaire (SF-MPQ) and 36 item Short Form Health Survey (SF-36). Results: After Korean medicine treatment, most of vesicles disappeared. NRS of chief complaints such as neuralgic pain and itchness changed 7-8 to 0 and therefore, quality of life of the patient was elevated sharply. Conclusions: This case shows that Korean medicine treatment is beneficial and safe for the patients who suffered from Herpes Zoster during pregnancy.

  • Tarsal tunnel syndrome is a nerve entrapment syndrome of posterior tibial nerve as it passes through the tarsal tunnel. The patient presented posteromedial malleolar swelling, palpable mass and pain, and was misdiagnosed as ganglion cyst in the other clinic. Aspiration and steroid injection were done for years, which had no significant effect on symptom relief. As skin lesion and pigmentation abruptly appeared around the palpable mass, MRI and physical exam were done in our hospital. The patient was diagnosed as varicose veininduced tarsal tunnel syndrome and therefore tarsal tunnel decompression following dilatated varicose vein resection was done. The patient's symptom was improved after the surgery. Therefore, herein we report this case.

  • Primary cutaneous mucinous carcinoma (PCMC) is a rare malignancy of the sweat glands that most commonly affects the periorbital area. It is characterized by slow growth over a prolonged period, and its morphology can be easily confused with a benign tumor, such as an epidermal cyst. Consequently, many patients experience recurrence after undergoing multiple resections. However, there are few reports concerning the surgical management of PCMC. We present two cases of PCMC originating in the periorbital area. The first case involved a 76-year-old man with a mass measuring 3.0×1.5 cm that had been increasing in size. The second case was a 61-year-old man with two masses, each measuring 1.0×1.0 cm, that were also growing. Both patients underwent wide excision with a 5-mm safety margin, which was determined based on the widest view of the cross-section of the mass on the magnetic resonance imaging. Subsequently, based on the intraoperative frozen biopsy results, both patients underwent additional excision with a 5-mm safety margin in only one direction. This report shows that, when determining the surgical margin of PCMC in periorbital area, employing imaging modalities and intraoperative frozen biopsies can be helpful for narrowing the surgical margin.

  • 신세포암은 소아에서는 드물지만 모든 연령에 걸쳐 신 세뇨관의 상피세포에서 기인하는 침습적 악성 종양이다. 종양이 국소화 되어있다면 주위 림프절 절개와 함께 국소적 신절제술로 완벽히 제거될 수 있으나, 주위 림프조직을 침범한 경우나 전이 병변이 동반된 진행된 신세포암 에서는 보조 화학치료, 방사선치료 및 면역치료 등을 이용한다. Sorafenib는 경구, 다(多) kinase (multikinase) 억제제로서 최근 전이성 신장 암에 사용이 입증되었다. 그러나 설사, 피로, 탈모와 고혈압 등의 부작용과 발진이나 낙설 그리고 수족 피부 반응(hand-foot skin reaction)과 같은 피부변화 등이 보고되었다. 특히, 손바닥과 발바닥의 홍반 피부 병변을 보이는 수족 증후군(hand-foot syndrome, HFS)은 대부분 세포증식 억제 화학치료 약에 의해 야기된다. 손바닥 발바닥의 홍반성감각부전으로 알려진 수족 증후군은 저림과 고온의 물체에 대한 과민성 같은 감각이상의 전구증상 등을 특징으로 하며, 약 3- 4일 후 원위 지관절에 홍반과 동통을 수반한 양측에 대칭적 손바닥과 발바닥의 부종이 생긴다. 저자들은 14세 여아의 전이성 신세포암 치료에 sorafenib 사용 시 나타난 수족 증후군과 그에 대한 치료를 경험하였기에 문헌고찰과 함께 보고하는 바이다.

  • 적외선 체열촬영술은 생리적, 기능적 이상유무를 평가하기 위해 수의와 인의에서 최근 사용되고 있다. 이 연구에서는 디지털 적외선 이미지 시스템을 사용하여 개의 등에서 피부의 절대온도와 상하 그리고 좌우 온도차를 알아보고, 실험적으로 유발한 척수 손상 시 적외선 체열촬영술의 임상적 유용성을 조사하기 위하여 실시되었다. 33마리의 건강한 비글견에서 등쪽 부분을 삭모한 후 정상체열상을 촬영하였으며, 7마리의 건강한 암컷에서 경막외 풍선카테터를 이용하여 척수손상을 유발하였다. 정상군은 체열영상에서 등고선과 같은 일정하면서도 대칭적인 양상을 보였으며, 상하, 좌우에 관계없이 유의적인 피부 온도차가 관찰되지 않았다 이와는 달리, 척수 손상군의 경우 척수손상부위 주위로 대칭적인 온도 감소가 있었다. 좌우의 온도차는 거의 없었으며 매우 안정적인 경향을 보였다. 특이한 점은 상하의 온도차 중에서 흉추부와 요추부 사이의 온도차가 현저하게 나타났으며, 수술 후 4주가 경과했을 때 거의 정상으로 회복되는 경향이 있었다. 이상의 결과로 보아 적외선 체열촬영술은 개의 척수 손상 시 진단 및 예후 평가를 위한 유용한 진단기법이며, 비정상 부위를 찾아내는 데 상하좌우의 정상 피부 온도차가 매우 유용할 것으로 사료된다. 또한 병변이 양측성인 경우, 좌우의 비교보다는 인접한 부위의 상하 온도차를 비교하는 것이 더 적절한 방법일 것으로 사료된다.
