서정아,김재곤,백병주,양연미,이용희,김상훈 大韓小兒齒科學會 2004 大韓小兒齒科學會誌 Vol.31 No.4
본 연구의 목적은 chlorhexidine(Cervitec)과 fluoride(Fluor-protector) 성분을 각각 포함한 varnish를 치아에 적용하였을 때 타액내의 mutans streptococci의 수의 감소에 미치는 효과를 알아보기 위한 것이다. 전북대학교 치과대학생 40명을 대상으로 하여 mutans streptococci 균종 수를 평가하였으며, 이들을 무작위로 네 군으로 나누어 다음과 같이 varnish를 적용하였다; A) varnish를 적용하지 않은 군(n=10), B) chlorhexidine varnish 적용군(n=10), C) fluoride varnish 적용군(n=10), D) chlorhexidine과 fluoride varnish를 모두 적용한 군(n=10), Mutans streptococci 수 측정에는 Orion diagnostica 사의 Dentocult SM을 사용하였다. Varnish를 적용하지 않은 상태에서 1차로 Mutans streptococci 수를 측정한 후 각각의 varnish를 적용하였으며, varnish 적용 12주 후 다시 측정하여 기록하였다. 모든 실험군(group B, C, D)에서 12주 후에 측정한 Mutans streptococci 수가 감소한 개체가 증가한 개체보다 많았으나 통계적으로 유의한 차이는 보이지 않았다(p>0.05). 실험에 사용된 어떠한 varnish도 적용 12주 후에 타액 내 mutans streptococci 수에 통계적으로 유의할 만한 변화를 주지는 못하는 것으로 나타났다(p>0.05). The objective of the present prospective trial was to compare the efficacy of chlorhexidine(Cervitec), Fluoride(Fluorprotector) and combination of chlorhexdine and fluoride varnishes in decreasing the level of salivary mutans streptococci. Forty healthy students of school of dentistry, Chonbuk national university were investigated to evaluate mutans streptococci(MS) counts and randomized into four groups to treat with the experimental varnishes: A) untreated group(n=10), B) chlorhexidine group(n=10), C) fluoride group(n=10), D) chlorhexidine and fluoride group(n=10). Dentocult SM^(�)(Orion Diagnostica) strip method was used for measurement of the level of mutans streptococci in saliva. Stimulated saliva were collected at baseline for mutans streptococci counts evaluation(ms1), 12 weeks later the completion of each varnish treatment, mutans streptococci counts were re-evaluated. In varnish group with chlorhexidine, fluoride and combination of chlorhexidine and fluoride, the level of mutans streptococci was lower after 12 weeks than at baseline, but there were no significant differences in saliva(p>0.05), when compared with baseline. After 12 weeks, a remarkable reduction was still found in the subjects with high level of mutans streptococci at baseline, but not different in the low and moderate level of mutans streptococci(p>0.05).
Horseshoe Appliance를 이용한 Ⅲ급 부정교합의 교정적 접근
한지혜,김재곤,,백병주,양연미,서정아 大韓小兒齒科學會 2005 大韓小兒齒科學會誌 Vol.32 No.4
성장기 아동의 Ⅲ급 부정교합의 치료에는 많은 악기능 정형장치가 사용되어 왔으며 다양한 형태로 변화하여 발전되어 왔다. Horseshoe appliance는 Schwarz에 의해 소개된 장치로서 elastic의 견인력으로 장치의 free sliding 효과를 통해, 하악와와 과두의 관계를 재정립시켜, 악골 주위의 연조직이나 muscle matrix와 조화되는 새로운 위치에 하악골을 repositioning시켜 악골관계를 개선시킬 수 있다. 또한 하악의 후하방 회전 효과를 극소화시켜 전안면고경의 증가를 방지할 수 있고, 구외 장치에 비해 환자의 협조도가 좋다. 저자들은 전치부 반대교합을 주소로 전북대학교 치과병원 소아치과에 내원한 Ⅲ급 부정교합 환자에게 Horseshoe appliance를 사용한 결과 하악골에 대한 상대적인 상악골의 전방 성장과 교합평면의 반시계방향 회전, 상악 전치의 순측 경사와 하악 전치의 설측 경사로. 3개월 내에 전치부 반대교합이 해소되는 효과를 얻었다. The Horseshoe appliance was introduced by Dr. Schwarz, and it is used to correct sagittal relationships by elastic force in class Ⅲmalocclusion.It minimizes the increment of lower anterior facial height and allows the mandible to be repositioned harmoniously with the soft tissue and muscle matrix of the jaw. It has the advantages of better patient cooperation, easier construction, and more effective modification. In the patients who were treated with Horseshoe appliance, forward growth of maxilla and counterclockwise rotation of occlusal plane with labioversion of maxillary incisors and linguoversion of mandibular incisors were obtained Minimum downward and backward rotation of mandible was accepted, so increasing of lower anterior facial height was minimized.

Background: Primary cutaneous anaplastic large cell lymphoma (pcALCL) is a subtype of cutaneous T-cell lymphoma histologically characterized by large, highly atypical CD30+ T-cells. They include two clinically different entities with some overlapping features and borderline cases: lymphomatoid papulosis and primary cutaneous anaplastic large cell lymphoma. Objectives: In this review, we discuss the clinical findings of the latest developments to pcALCL including findings for diagnosis, prognosis, and therapeutic modalities. Methods: We performed a descriptive retrospective study to identify characteristics and distribution of pcALCL patients with purpose of influencing factors. Results: This study shows that patients with pcALCL typically present with solitary or localized nodules or tumors (75%) or, more unusually, papules (12.5%), with frequent ulceration (62.5%) and rapid evolution in some cases (25%) that may simulate and/or appears as progressive lymphomas (75%). Conclusion: This study shows that a clinician keep in mind a variety of clinical features of pcALCL making an accurate diagnosis through early histopathologic examination will lead to better prognosis.

Background: To date, the clinical benefit of topical steroid use has only been demonstrated for radiation dermatitis induced by 50-60Gy in breast cancer. Radiation dermatitis is characterized by erythema, itching, pain, and burning sensation, and there is no consensus on how to prevent it. Objectives: In this study, we clarify the additional benefit of topical steroid and preventive emollient care for radiation dermatitis induced by high-dose (>60Gy) irradiation with chemotherapy in advanced squamous cell carcinoma of the head and neck (SCHN) patients. Methods: Patients with definitive chemoradiotherapy (CRT), when radiation dermatitis grade 1 is seen or total radiation dose reaches 30Gy. If radiation dermatitis worsens to grade 2, the irradiated area will be covered with a moderately absorbent surgical pad only or steroid and topical cream with it. Results: The median radiation dose before the development of grade 2 skin toxicity was <60.5Gy in patients with SCHN. Almost of patients (85.7%) complained burning and local erosion during planned CRT. Standard care was initiated on 78.5% of patients during the study (surgical pad: 78.5%, steroid only:14.4%, emollient only:21.4% both:50.0%). The most effective prescribed modalities in all arms were steroid with emollient in surgical pad covering. Conclusion: This study shows that the clinical benefit of topical steroid and emollient for radiation dermatitis induced by high-dose irradiation with chemotherapy.
