모든 과개교합을 가진 환자를 병적인 상태로 판단할 수는 없지만 전치부에 교합접촉이 불안정하거나, 전반적인 교합 부조화가 동반된다면 과개교합은 하악 전치에 대한 지속적인 마모와 정출을 일으킬 수 있다. 이 증례는 72세 남성환자로 상악과 하악의 전치가 잔존해 있지만 골격성 2급 부정교합으로 인하여 안정위 상태에서 교합접촉이 불가능하고 교합지지가 완전히 상실되어 수직고경의 증가가 필요한 환자였다. 이 증례는 보철 수복을 위해 수직고경의 증가가 필요한 경우로 수평피개를 더욱 심화시켜 교합의 부조화를 유발할 수 있기에 정밀한 진단을 통한 수직고경 증가량 결정이 필요하였다. 이 증례에서는 Dahl concept를 응용한 가철성 국소의치 보철물을 이용하여 안정적인 교합을 완성하였으며 적절한 치료 결과를 보였기에 이를 보고하고자 한다.

최근 들어 치아의 심미적인 개선을 위해 전치부 보철 치료를 하는 경우가 많다. 하지만 전치부 심미 보철치료이후 환자가 발음, 저작 등 기능적으로 불만족스럽게 생각하는 경우가 종종 있다. 전치부는 심미적으로 중요할 뿐만 아니라 교합과 관련하여서도 중심위 다음으로 중요한 전방유도가 성립되는 부분으로, 잘못된 전방유도 설정으로 인해 구치부의 교합간섭을 초래할 수 있다. 또한 새롭게 설정된 전치부 보철물의 전방유도가 환자의 기능로(envelope of function)과 조화를 이루지 않을 시 환자가 불편감을 나타낼 수 있다. 본 증례는 전치부 심미 보철 이후 부정확한 발음 및 안정적인 접촉이 없어서 불안정한 교합, 전반적인 불편감을 호소하는 환자에서 체계적인 진단과 치료과정을 통해 보철물을 재수복하여 환자와 술자 모두에게서 심미적으로, 그리고 기능적으로 만족스러운 결과를 얻었기에 보고하는 바이다.

■ Objectives The goal of this pilot study is to observe the change of gait pattern in a patient after peroneal nerve electrical stimulation(PNST). ■ Methods We analyzed the gait pattern of stroke patient using treadmill gait analysis system before and after PNST for seven weeks. The PNST was carried out for 20minutes every day except Sunday. In addition, the measurement was carried out every Saturday. At the fifth week, the PNST was not carried out to confirm whether the effect of PNST was disappeared immediately when PNST was not applied. ■ Results After PNST, while heel contact time and heel max force increased and forefoot and midfoot max force decreased, the gait parameters such as cadence, velocity, swing phase, stance phase, total double support, step length, stride length, step time, stride time and forefoot contact time, were not changed. ■ Conclusion Gait of a patient with cerebral stroke was changed positively after PNST.

Objectives : The dried root of Sophora flavescens Aiton have been used to treat patient with skin diseases such as eczema in Eastern countries. S. flavescens can clear away heat and dry dampness and purge sthenic-fire from the liver and gallbladder. Recently, anti-allergic effect of S. flavescens has been reported. However, the effect on skin condition of contact dermatitis still remains unknown. Thus, the purpose of this study is to evaluate the efficacy of S. flavescens on contact dermatitis. Methods : In order to investigate the effects of S. flavescens (methanol extract of S. flavescens, MESR) on skin condition, the contact dermatitis was induced in mice skin by using 1-fluoro-2,4-dinitrofluorobenzene (DNFB). As the effective endpoints, skin thickness, skin weight, histopathological change were checked. In addition, effects on skin lesion, body weight and spleen/body weight ratio were also investigated. Results : Topical application of MESR ($500{\mu}g/day$) lowered skin thickness (P < 0.05) and skin weight (P < 0.05), respectively. MESR-treated group showed diminished spongiosis and immune cell infiltration in skin tissues compared to those of non-treated control group. The inhibition of skin lesions was also observed in MESR-treated group. In addition, MESR did not affect body weight gain and spleen/body weight ratio in contrast with those in dexamethasone-treated group. Conclusion : These data suggest that Sophorae Radix could improve skin lesion of contact dermatitis. This indicates the possibility for Sophorae Radix to be used to patients with skin diseases such as contact dermatitis.

In the field of otolaryngology-head and neck surgery, botulinum toxins are widely used for the treatment of spasmodic dysphonia and vocal tremors. Recently, the applications of botulinum toxin have gradually expanded with time, to include vocal fold granuloma, mutational falsetto, bilateral vocal cord paralysis, and chemical reduction for arytenoid dislocation as an adjunctive modality. According to a nation-wide multicenter study conducted by the Korean Society of Laryngology, Phoniatrics and Logopedics for treatment modality of contact granuloma, among the various treatment modalities, botulinum toxin injection showed the highest response rate and lowest recurrence rate in both primary and refractory cases. Therefore, botulinum toxin could be reserved as a second-line treatment for contact granuloma in which the first treatment was not effective, but also could be used as a first-line treatment depending on the patient's and institution's situation. For recalcitrant nodules, injection of botulinum toxin into the bilateral thyroarytenoid muscle will reduce glottal contact force and result in a forceful chemical voice rest. In special situations, botulinum toxin injection could be one of the alternative treatment options for recalcitrant vocal nodules.

Objective : The purpose of this report is to know the effect of oriental medical treatments on acute allergic contact dermatitis with multiple nummular eczema. Methods : We treated a 34-years-old woman patient with acute allergic contact dermatitis on face and multiple nummular eczema on both arm, right ankle and left inguinal region by Korean medicine. After Korean medical treatment for 42 days in hospital, we measured the decrease of exudation and pruritis as well as recovery of skin damages. We recorded pictures of changes on symptoms. Results & Conclusion : The symptoms of ACD and nummular eczema were significantly improved except scars. Exudation and pruritis were disappeared and skin damages were almost recovered until discharge from hospital. After 20 days we could confirm the symptoms were clearly disappeared. Thus Korean medical treatments are effective on ACD and nummular eczema.

We conducted both the small subunit ribosomal DNA (SSU rDNA) polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and mitochondrial (mt) DNA RFLP analyses for a genetic characterization of Acanthamoeba isolates from contact lens storage cases of students in Seoul, Korea. Twenty-three strains of Acanthamoeba from the American Type Culture Collection and twelve clinical isolates from Korean patients were used as reference strains. Thirty-nine isolates from contact lens storage cases were classified into seven types (KA/LS1 , KA/LS2, KA/LS4, KA/LS5, KA/LS7 KA/LS18, KA/LS31). Four types (KA/LS1 , KA/LS2, KA/LS5, KA/LS18) including 33 isolates were regarded as A. castellanii complex by riboprints. KA/LS1 type was the most predominant (51.3%) in the present survey area, followed by KA/LS2 (20.9%), and KA/LSS (7.7%) types. Amoebae of KA/LS1 type had the same mtDNA RFLP and riboprint patterns as KA/E2 and KA/E12 strains, clinical isolates from Korean keratitis patients. Amoebae of KA/LS2 type had the identical mtDNA RFLP patterns with A. castellanii Ma strain, a corneal isolate from an American patient as amoebae of KA/LS5 type, with KA/E3 and KA/E8 strains from other Korean keratitis patients. Amoebae of KA/LS 18 type had identical patterns with JAC/E1, an ocular isolate from a Japanese patient. Three types , which remain unidentified at species level, were not corresponded with any clinical isolate in their mtDNA RFLP and riboprint patterns. Out of 39 isolates analyzed in this study, mtDNA RFLP and riboprint patterns of 33 isolates (84.6%) were identical to already known clinical isolates, and therefore, they may be regarded as potentially keratopathogenic. These results suggest that contact lens wearers in Seoul should pay more attention to hygienic maintenance of contact lens storage cases for the prevention of Acanthamoeba keratitis.

"Chimumchang" seems to be a kind eczema. The cause and symptom of eczema is similar to that of chimumchang. so, I investigated the literatures of oriental medicin and recent medicine. The results are summarized as follows. 1. Chimumchang seems to be a kind of eczema. Allergic contact dermatitis, atopic dermatitis, seborrheic dermatits, neurodermatitis, nummular dermatitis, xerotic eczema and so on are similar to chimumchang on cause & symptom. 2. The cause of chimumchang are summer vital energy excess(夏脈太過), sehwa excess(歲火太過), herat meridian wind-heat(心經風熱), heart fire(心火), wind taken spleen dampnees(脾濕受風), and so on. The cause of eczema are contact of external agent, immunological problem, heridity, infection, abnormalities of sebaceous glands, neurologic dysfuction, and so on. 3. The symptoms of chimumchang have been described to the three pattern on literature of oriental medicine until now. 1) scratching slightly, It has exudation, and combination. 2) Vital energy on skin is irritable by psychological problem. At the acute stage the patient is complain of itching & pain, and gradually the exudation expands in whole body. 3) early peorid it's size is very small, and at first the patient is complain of itching, later complain of pain. The exudation change to ulcer and expands in the whole body. 4. In the investigation of prescription(Total: 34, Oral medicine: 4, Ointment: 30), the most frequently used oral medicine is sungmatang(4 times), and the most frequently used ointment are kohosan, korvunsan and kegwanhyuldobang.

Implant-supported restorations were connected to commercially pure titanium endosteal implants 3 months in mandible and 6 months in maxilla after the implants were inserted into patient jaws. Modifications of titanium implant surfaces have reduced the waiting time for osseointegration, resulting in the development of the early loading concept, which is defined at present as a restoration in contact with the opposing dentition and placed at least 1 week after implant placement, but no later than 2 months afterward. Nowadays, immediate loading protocols have also been introduced, using the implants that are designed to enhance initial stability. Immediate loading eliminates the edentulous period of a patient. Although dentists widely accept these concepts of early and immediate loading, they agree the conventional loading concept is still necessary, which describes loading protocols later than 2 months after implant insertion. The timing of loading is determined mainly by the factors of a patient. This paper considers for what dental clinicians should be careful in implant-supported restoration procedures, considering the implant late failure.
