비듬균(Malassezia furfur) 는 두피 질환을 일으키는 중요한 요소로써 오늘날 이러한 균들을 치료하는 치료제는 거의 없다. 몇몇의 전의 연구에서 오일들의 다양한 생물학적 활성이 보고되어졌지만 그것들의 항비듬균 활성은 거의 연구되지 않았고, 특히 Malassezia furfur에 대한 저해 활성은 보고되어 있지 않다. 따라서, 이 연구에서는 Malassezia furfur에 대한 식물 오일들의 저해활성을 평가하고, 이러한 오일 중에서 가장 활성이 좋은 오일을 가스 크로마토그래피(Gas chromatography-mass spectrometry)에 의해 성분을 분석하였다. 1차적으로 108개 오일의 스크리닝 과정에서 17개 오일[Allium sativum L., Carum carvi L., Coriandrum sativum L., Myroxylon balsamum var. pereirae Royle, Nepeta cataria L., Origanum vulgare L., Mentha pulegium L., Satureja hortensis L., Thymus vulgaris L. Thymus vulgaris L., Cinnamomum zeylanicum Blume, Pimenta dioica(L.) Merr., Eugenia caryophyllata Thumb.(Clove bud), Eugenia caryophyllata Thumb.(Clove leaf), Cymbopogon nardus L., Cymbopogon martinii Stapf., Citrus aurantifolia Swing. and Pimenta racemosa(Mill.) J.W.Moore] 이 2 mg/mL 의 농도에서 대조구인 이크라코나졸(itraconazole)과 비슷한 활성을 나타내었다. 이러한 17개 오일 중에서 Citrus auranifolia 오일이 가장 활성이 좋았으며, 처리농도 (1.5 mg/mL, 1.0 mg/mL, 0.5 mg/mL와 0.1 mg/mL) 에 따라 활성이 감소하는 경향을 보였다. 또한 Citrus auranifoli 오일의 가스크로마토그래피(GC-MS) 성분분석 결과 limonene, ${\gamma}$-terpinene and terpinolene의 함유율이 높은 것으로 나타났다. 그러므로 Citrus auranifolia 오일은 곰팡이 유래 질병들을 치료하기 위한 활성성분을 함유하고 있는 것으로 보인다.

Marjolin's ulcer is a rare and often-aggressive cutaneous malignancy that arises in previously traumatized or chronically inflamed skin, particularly after burns. We experienced two cases after burns. Case I involved a forty eight year-old man who had suffered from a flame burn at the parietal scalp area, where had been initially described three years earlier as a full-thickness wound including the pericranium. The man consulted us for a persistent ulcerative and infected wound on the burned lesion during the last 24 months, which turned out on the contrast-enhanced computed tomography (CT) and magnetic resonance imaging (MRI) to be the squamous cell carcinoma with involving the skull and the dura mater. Although the posterior auricular lymph node was enlarged on the ipsilateral side, recent positron emission tomography (PET) CT did not show any metastatic lesion. It was impossible for us to resect the intracranial involvement of the tumor radically, and the postoperative PET CT still showed a focal fluorodeoxyglucose (FDG) uptake around the wall of the superior sagittal sinus. We think that an aggressive combined approach is essential for treatment in early stages for a high success rate, before the intracranial structures are involved because there is no consensus on the treatment for advanced disease, and the results are generally poor. Case 1 also did not involve a radical resection because of the intracranial invasion to the wall of superior sagittal sinus and the possibility of damage to the major cortical veins. He received adjuvant radiotherapy and must be followed periodically. Case 2 involved an eighty six year-old women who suffered from a painful scalp ulcer lesion after flame burns three years earlier. Unlike case 1, neither tumor infiltration into the dura nor lymph node enlargement was observed on the contrast-enhanced computed tomography (CT), magnetic resonance imaging (MRI), or positron emission tomography (PET) CT. We did a radical resection of the tumor, including the involved bone, and a cranioplasty with bone cement.

Purpose: Scalp avulsion is a life-threatening injury that may cause trauma to the forehead, eyebrows, and periauricular tissue. It is difficult to treat scalp avulsion as it may lead to severe bleeding. Therefore, emergency scalp replantation surgery is necessary, and we must consider the function, aesthetics, and psychology of the patients. A case of scalp avulsion leading to massive bleeding was encountered by these authors, which led to a failure to achieve the proper operation conditions in an adequate time period. Methods: A 49-year-old female was hospitalized due to having had her head caught in a rotatory machine, causing complete scalp avulsion which included the dorsum of the nose, both eyebrows, and ears. Emergent microsurgical replantation was performed, where a superficial temporal artery and a vein were anastomosed, but the patient's vital signs were too unstable for further operation due to excessive blood loss. Three days after the microanastomosis, venous congestion developed at the replanted scalp, and a medicinal leech was used. Leech therapy resolved the venous congestion. A demarcation then developed between the vitalized scalp tissue and the necrotized area. Debridement was performed 2 times on the necrotized scalp area. Finally, split-thickness skin graft with a dermal acellular matrix ($Matriderm^{(R)}$) was performed on the defective areas, which included the left temporal area, the occipital area, and both eyebrows. Results: The forehead, vertex, right temporal area, and half of the occipital area were successfully replanted, and the hair at the replanted scalp was preserved. As stated above, two-thirds of the scalp survived; the patient could cover the skin graft area with her hair, and could wear a wig. Conclusion: Complete scalp avulsion needs emergent replantation with microsurgical revascularization, but it often leads to serious vital conditions. We report a case with acceptable results, although the microanastomosed vessel was minimal due to the patient's unstable vital signs.

Purpose : We aimed to validate a new manual therapy to treat tension type headache(TTH) by applying myofascial release techniques to the scalp and to examine the changes in the quality of life and the headache characteristics after treatment and at the 6-month follow-up. Methods : Thirty patients were recruited in this study and were assigned to two groups through simple random sampling. Fifteen patients were assigned to the manual therapy group (MT) and 15 patients to the scalp myofascial release technique (SMT) group. However, five patients from the MT group and one from the SMT group were excluded. Therefore, 24 patients with TTH (10 males, 14 females) participated in the study. Patients underwent either MT or SMT. The procedures were performed by a physical therapist twice per week for 4 weeks. The quality of life [using the brief pain inventory (BPI) and the headache impact test (HIT)], and the frequency, duration, and intensity of the headache [on a visual analog scale (VAS)] were assessed before and after the treatment, and at the follow-up. Results : After 4 weeks of SMT, the frequency (p<.001), duration (p<.05), and intensity (p<.001) of the headache and the quality of life (HIT; p <.001, BPI; p<.001) significantly improved in the patients with TTH. The improvement in these parameters remained significant even after 6 months of follow-up. Similarly, After 4 weeks of MT, the frequency (p<.05), duration (p<.05), and intensity (p<.01) of the headache, and the quality of life (HIT; p<.05, BPI; p<.001) significantly improved in the patients with TTH. The improvement in these parameters remained significant even after 6 months of follow-up. There was no significant difference in these parameters between the two groups. Conclusion : It has been suggested that MT using the SMT can be used as a non-invasive treatment to treat the frequency, duration, and intensity of the TTH, and to improve the quality of life.

Objectives : The objective of this study is to report a case of a male atopic dermatitis patient accompanying seborrheic capitis and nummular eczema improved by Korean medicine therapy and lifestyle modification. Methods : A male patient was hospitalized for eczematous lesions in the head, face, and both hands which relapsed on March 2021. For 15 days, he took Korean medicine therapy including acupuncture, Bangpungtongseongsan-gagam, pharmacopuncture, and wet dressing with Hwangryunhaedok-tang. Simultaneously, lifestyle correction also conducted during administration. On the other hand, corticosteroid and antihistamine were prescribed from internal medicine of our hospital for the first 10 days because of severe skin lesions. As an outpatient, he was continuously treated by the same Korean medicine therapy except herbal decoction weekly for about 7 months after discharge. To assess symptoms, scoring atopic dermatitis(SCORAD) index, taking photos, and numerical rating scale(NRS) were used. Results : After 15 days of hospitalization, the SCORAD index decreased to 30.0, which was about a half of the initial SCORAD index(61.2). NRS score also dropped from 6 to 3. Despite stopping western medicine administration, skin lesions and subjective symptoms of the patient were steadily improved without aggravation. For 7 months of continued outpatient treatment, atopic dermatitis were steadily ameliorated despite temporary aggravation and improvement of symptoms, and seborrheic capitis was not relapsed. The final SCORAD index and NRS on November 9th, 2021 were 24.7 and 1, respectively. Conclusions : These results suggests that Korean medicine therapy contributes to improving SCORAD index, subjective symptoms, and skin lesions of the patient. Furthermore, lifestyle modification is also important as much as proper treatment for caring atopic dermatitis patients.
