In this study, "housewives" are defined as married women who take care of housework mostly and do not work outside of home. Changing family types and higher education level of housewives enable them to be more interested in heath, beauty, and appearance. Increased interest and more frequent visits to hair salons cause scalp damage as well as hair damage, which results in hair loss. Moreover, some women suffers from scalp and hair damage due to childbirth, but many of them are not aware of it. Therefore, this study tries to find out the following; housewives' perceptions on hair and scalp management, and how such perceptions are formed. In addition, this study will present the direction for beauty marketing taking into account the characteristics of housewives and provide data necessary for them to keep their hair and scalp healthy. For these purposes, a survey was carried out after modifying the questionnaire through a presurvey. The survey tried to find 1) perceptions on hair and scalp management according to demographic characteristics, and attitude toward hair and scalp management according to demographic characteristics. Data were analyzed using frequency analysis, cross tabulation, t-test, factor analysis, and Analysis of Variance. The results were as follows, most recognize the importance of hair and scalp management but do not receive management because of the high cost, most of them receive information about hair and scalp management from people around them, and the higher the education level and health status, the more active the attitude toward hair and scalp management. These differences were all statistically significant.

Le Fort II 골절단술 및 전방 이동술은 비상악골의 형성 부전증이나 짧은 코, 또는 상악골에 대비하여 상대적인 하악 전돌증 환자에 있어 고려 대상이 되어 왔다. 이러한 비상악골 형성 부전증의 원인으로는 외상, 토순 또는 구개열로 인한 발육부전, 선천성 매독증과 같은 감염 증상 등을 들 수 있다. Le Fort II 골절단술 및 전방 이동술은 1973년 Henderson 과 Jackson 에 의해 처음으로 보고되었고, 그 후 1980년 Steinhauser, Kinnebrew 등에 의해 변화되어 왔다. Le Fort II 골절단술에 있어서의 관상 절개술은 paranasal incision에 비해 안면부 술후 반흔이 남지 않아 심미적으로 우수하며, 두부의 상부 1/2까지 노출이 가능하여 수술시야가 좋으며, 안면 신경 손상 및 lacrimal apparatus 손상의 위험이 적다는 장점 이 외에도 nasofronatal osteotomy site와 pterygomaxiliary osteotomy site를 위한 bone graft의 donor site로서 skull bone을 immediate로 사용할 수 있다는 장점이 있다. 본 교실에서는 선천성 매독의 후유증의 하나인 비상악골 형성부전증을 가진 23세의 여자 환자에 있어서 관상 절개술을 통한 Le Fort II 골절단술을 통한 전하방 이동 및 하악지의 시상골 절단술을 시행하여 양호한 결과를 얻었기에 이에 보고하는 바이다.

We present a recordings of 37-year-old woman with simultaneous ictal scalp and subdural electrodes. The ictal rhythm on subdural electrocorticography (ECoG) started earlier (median 24.5 sec) and ended later (median 2.0 sec) compared to ictal rhythm on scalp EEG. Eight ictal ECoG recordings were well localized to left temporal area, whereas ictal scalp EEG recordings were not. Our case shows the obvious timing relations between two recordings, and different electrophysiologic information about localization of ictal onset zone.

Purpose: Angiosarcoma is a rare malignant neoplasm of endothelial type cells that line vessel walls. It tends to occur in aged male and the prognosis of angiosarcoma is very poor because of frequent local recurrence and early metastasis. The treatment regimen is yet to be established from its rare occurrence but the wide excision in early stage is known to be the most effective. The authors report two cases of near totally excised angiosarcoma with more than a safety margin of 5 cm. Methods: The two subjects were aged male patients, one of the two was diagnosed with angiosarcoma from our institution confirmed by the biopsy. The other one went through the wide excision with a safety margin of 2 cm and split-thickness skin graft but local recurrence was observed. The two patients underwent near total excision with more than a safety margin of 5 cm, leaving only the periosteum. After confirming that the angiosarcoma had not infiltrated the excision margin, reconstruction with split-thickness skin graft was performed. Results: Based on 6 months and 24 months post-surgery assessment, no local recurrence or remote metastasis in the lungs, liver, bones, and lymph nodes at the neck, where remote metastasis is common, was reported by the two subjects who underwent near total excision with a safety margin of 5 cm. Conclusion: Angiosarcoma has very poor prognosis from its frequent recurrence and metastasis. To enhance the survival rate of angiosarcoma patients, early diagnosis, timely surgical treatment, and radiotherapy after surgery are critical. In addition, authors suggest that it is necessary to further study the efficacy of wide excision using a wider safety margin as much as possible, and to apply this to more cases.

The aim of this study was to investigate the major vascular system to supply flap, flap survival rate and complications after flap elevation in order to evaluate possibility of the vascularized face/scalp allotransplantation. Forty New Zealand white rabbits were divided into two groups: control group and experimental group. Individuals of control group had a face/scalp composite unit which was composed of skin, subcutaneous tissue and platysma muscle, supplying by bilateral facial artery, temporal artery and auricular artery and draining by external jugular vein. After a flap was elevated, bilateral facial artery, temporal artery and auricular artery were ligated. On the other hand, those of experimental group had the same composite unit as control group with bilateral facial artery, temporal artery and auricular artery being not ligated. We had measured survival area of flaps of the sixteen individuals survived for four weeks in the control group and fourteen in the experimental group by Grid method. The mean survival durations of the flap were 3.7days in the control group, 20.0days in the experimental group. The significant differences in the mean survival durations and survival rate at the 28days were found between the control and experimental group (p<0.05). Mean values about the survival area's fractions of all were $1.3{\pm}4.%$ in the control group and $63.1{\pm}4.8%$ in the experimental group. Those of experimental group was significantly higher than control group statistically (p<0.05). The composite face/scalp flap which we have elevated, supplied by bilateral facial artery, temporal artery, auricular artery and drained by external jugular vein has flap viability enough to be transplanted after its elevation.

Purpose: Pyoderma gangrenosum is a rare inflammatory, reactive dermatosis marked by painful cutaneous ulcer. The causes of pyoderma gangrenosum remain unclear. Gastrointestinal, hematological, rheumatological, and immmune disorders may be associated with pyoderma gangrenosum. The appearance of this disease may range from mild skin ulcers to life-threatening conditions. Generalized multiple ulcerative pyoderma gangrenosum is very rare. Here we report our experience with a case of multiple ulcerative pyoderma gangrenosum accompanied by ulcerative colitis. Methods: A 67-year-old man had cutaneous ulcers at multiple sites including the scalp, face, chest, abdomen, hands, and buttocks. He also developed gastrointestinal symptoms such as intermittent dyspepsia and bloody excrement. Debridement and irritation aggravated the disease progress. We gave a diagnosis of pyoderma gangrenosum with ulcerative colitis based on the clinical appearance and biopsy. The patient was treated with systemic intravenous steroid therapies and careful wound cares. Ulcers of the scalp and buttocks were treated with split thickness skin grafts. Results: Most of the multiple cutaneous ulcers were treated by systemic intravenous steroid therapies and wound cares. The rest of the ulcers were treated with skin grafts. Systemic intravenous steroid therapy was used to treat the ulcerative colitis. Conclusion: Generalized multiple ulcerative pyoderma gangrenosum is very rare. Without making an accurate diagnosis, hasty surgical treatments could aggravate the progression of the disease. Additionally, care should be taken to systemically treat underlying disease as well as administrating local treatments for the skin lesions. Intravenous systemic steroid therapy and skin grafts are useful treatments for generalized pyoderma gangrenosum.

Purpose: There have been few case reports regarding treatment plans for long-term, neglected scalp defects and calvarial defects with subdural abscess. The purpose of this case report is to present our experience with a free latissimus dorsi musculocutaneous flap for scalp and calvarial defects and to discuss flap options in comparison with a literature review. Methods: A 60-year-old man who fell down from a four-story-height that resulted in a craniotomy in 1979; he visited our outpatient clinic for a chronic, purulent scalp and calvarial defects with unidentified artificial bone. The artificial bone was removed by a neurosurgeon and reconstructed with a free latissimus dorsi musculocutaneous flap. The deep temporal artery was used as a recipient artery. The postoperative flap status was excellent until the 6th day post-operation when the patient experienced a seizure, and an arterial insufficiency occurred at the flap probably due to an arterial spasm. Emergency exploration with arterial re-anastomosis was performed and the flap status was stabilized. Results: Complete wound healing was achieved after 3 weeks without infectious and systemic postoperative complications. During the 6 month follow-up period, there were no complications. Conclusion: We suggest the latissimus dorsi myocutaneous free flap as a good treatment option for a chronic, purulent, complicated scalp with calvarial defect, as a well as treatment for an acute traumatic defect.
