Malignant peritoneal mesothelioma is a rare neoplasm that arises from the mesothelium of a serosal cavity and is a rapidly fatal disease with a median survival of 4 to 12 months for untreated cases. Recently, we experienced a case with malignant peritoneal mesothelioma who was suspected hepatocelluar carcioma by abdominal CT scan and was confirmed by biopsy including immunohistochemical stain(calretinin) after surgery. We performed tumor excisions and wedge resection of the liver(segment Ⅷ)and inserted Tencoff catheter in abdominal cavity at 25th day of post-operation. We treated with intraperitoneal paclitaxel(25mg/m^(2)/day for 5 days) six courses monthly. She was well tolerable and is still living without any evidence of recurrence for 14th month of post-operation.

Transbronchial lung biopsy(TBLB) is a relatively simple and convenient diagnostic tool in solitary pulmonary nodule(SPN) on chest radiograph, which is cannot be diagnosed through routine tests. To investigate the diagnostic value and diagnostic rate of TBLB according to the variable factor, we analyzed 69 patients with radiologically SPN lesion on chest radiograph which was confirmed histologically. A histologic diagnosis of TBLB was made in 47 of 69 patients(68.1%), in which 26 of 37(70.3%) with malignancy and 21 of 32(65.6%) with benign lesion. There were no significant differences in diagnostic yield according to age, sex and location of the lesion. The diagnostic rate tended to increase with the more than 5 pieces to acquired by TBLB. When the size of SPN was less than 3 ㎝, it cannot be diagnosed. In conclusion, TBLB is a diagnostic procedure with good yield and safety, but percutaneous needle aspiration, transbronchial needle aspiration, and bronchial washing fluid cytology may be a complementary procedure to overcome the limitation of TBLB and get higher diagnostic yield for SPN.

교정치료와 악교정 수술을 필요로 하는 환자가 점증하는 현 시점에 비추어, 이에 대한 기술적인 측면의 발전과는 달리 수술-교정 치료 환자에 대한 정신사회학적 혹은 정신심리적 양상에 대한 객관적인 정보는 그리 많은 주목을 받는 편이 아니었다. 수술-교정치료는 과학적인 치료과정이긴 하지만, 어느 정도 심미적 혹은 예술적인 측면을 지니는 선택 치료의 면모를 지닌다. 그러므로 치료에 대한 환자의 주관적인 느낌은 치료 기술이나 치료의 의학적 성공 여부보다 더 큰 영향을 미칠 수 있다. 그러므로, 수술-교정 (혹은 교정) 치료에 대한 환자의 반응을 예측하기 위한 정신심리적인 정보는 치료에 유용한 지표가 될 수 있다고 가정할 수 있다. 통제 소재에 대한 연구는 인간의 다양한 행동을 예측하기 위한 유용한 지표로 알려져 왔는데, 본 연구에서는 42명의 수술-교정치료 환자와 성별/연령별로 표본 추출된 42명의 통상적 교정치료 환자를 대상으로 삼아 정신=심리적 비교 및 분석의 방법으로 두 가지 종류의 내외 통제 소재(internal/external locus of control) 검사를 시행하였다. 그 결과 수술-교정치료군에서만 남자가 여자에 비하여 낮은 외적 통제(높은 내적 통제)의 경향을 보였다. 결론적으로 수술-교정치료 환자의 정신심리적 기반은 성형 수술 환자와는 달리 교정치료 환자와 유사한 경향을 지닌 것으로 생각되었다. Surgical-orthodontic treatment is an increasingly more common dental procedure whose unique psycho-social or psychological feature has not been fairly quantified objectively. Since the treatment of a surgical-orthodontic (or orthodontic) patient is part science and part art, a subjective recognition of a patient about his or her own treatment may be more important than technical success during and after treatment. Therefore, the knowledge of the patient''s underlying psychological status could be useful in the prediction of patient's response to surgical-orthodontic (or orthodontic) treatment. The purpose of this study was to investigate and evaluate the psychological difference between conventional orthodontic patient and surgical-orthodontic patient by using locus of control (LOC) examination. Locus of control scale has been proven to be extremely useful in the prediction of a variety of human behaviors. Two types of locus of control data (I-score, Internal locus of control score ; E-score, External locus of control score) were obtained for 42 surgical-orthodontic patients and randomly selected 42 conventional orthodontic patients (as a control group) matched for age and gender. No statistically significant difference was observed in the scale of internal and external locus of control between the groups of surgical-orthodontic patients, males showed lower E-score (external locus of control score, higher internal locus of control tendency) than females. The results of this study suggested that the psychological background of surgical-orthodontic patients, in contrast with that of cosmetic surgery patients, has a similar disposition with that of orthodontic patients.

자일리톨과 불화나트륨을 함유한 저작성 정제가 교정환자의 구강위생에 미치는 영향에 관한 임상시험

유상훈,안석준,이신재,백승학,김태우,장영일,남동석 대한치과교정학회 2003 대한치과교정학회지 Vol.33 No.2

본 연구는 불화나트륨과 자일리톨 성분으로 구성된 구강 청정용 저작성 정제(덴포정, 하미즐, 부천, 경기)가 교정치료 중인 환자의 구강위생 상태에 미치는 영향을 알아보기 위해 시행되었다. 교정치료 중인 18세 이상의 성인 환자 30명을 대상으로 약제 상요 전, 2주 후, 4주 후에 피험자의 상악과 하악 전치 부위 및 구치 부위에서 각각 치은 지수, 치은 출혈 지수, 치태 지수를 측정하여 다음과 같은 결과를 얻었다. 1. 상하악 전치부와 구치부 모두에서 치태 지수가 약제 사용 전에 비해 사용 2주 후와 4주 후 유의성 있게 감소하였다(p<0.05). 또한, 적용 2주 후와 4주 후의 지수를 비교하였을 때 4주 후에 좀 더 개선된 경향을 보였으나, 통계적 유의성은 나타나지 않았다(p<0.05). 2. 치은 지수, 치은 출혈 지수도 상하악 전치부와 구치부 모두에서 적용 전에 비하여 2주 후와 4주 후 유의성 있게 감소하였다(p<0.05). 적용 2주 후와 4주 후의 지수의 비교 검증에서 통계학적으로 유의할 만한 차이가 보이지 않아 구강위생 상태의 개선이 계속 유지됨을 보였다. 본 연구의 결과는 치태 지수, 치은 지수, 치은 출혈 지수가 실험 정제 적용 후에 감소하여 구강위생 상태가 개선되었음을 보였다. 이러한 결과를 통해 덴포정을 교정치료 중인 환자에서 부가적으로 사용하였을 경우 치주조직의 건강을 증진시키는데 도움을 줄 수 있으리라고 생각된다. The aim of this study was to evaluate the effect a chewable tablet containing sodium fluoride and xylitol (DenPo, Hamizzle, Bucheon, Kyungki) on the oral hygiene state in the orthodontic patients. The subjects consisted of 30 adult orthodontic patients, who have worn the fixed orthodontic appliance at least 6 months. They were instructed to use the tablet forth a day. Gingival index (GI), plaque index (PI), and sulcus bleeding index (SBI) of upper and lower anterior and posterior regions were measured before using the tablet (TO), 2 weeks after using the tablet (T1), and 4 weeks after using the tablet (T2). The data were analyzed with Wilcoxon signed ranks tests. The results were as follows ; 1. PI was decreased significantly in the T1 and T2 stage compared with TO stage in the both anterior and posterior regions (p<0.05). Although PI was decreased in the T2 stage compared with T1, there was not statistical significance(p>0.05). 2. GI and SBI showed similar results compared with PL. In the T1 and T2 stage, there was statistically significant decrease in the GI and SBI (p<0.05). This study showed that the DenPo tablet could be used as an adjunct to improve oral hygiene in the orthodontic patients. The decrease of the indices may suggest that DenPo tablet could be effective in the plaque removal and prevention of gingival inflammation in the orthodontic patients.

The authors analysed 53 cases of sudden cardiac death(SCD) without prominent structural abnormalies of heart out of witnessed 300 cases. Thirty four cases were associated with sleep and 19 with activity or rest. Twenty one cases were classified as having normal hearts, and the rest as structurally mild abnormal ones. Male was predominant, and almost of the victims were suffered in their twenties or thirties. All cases collapsed instantaneously or in very short time with various and not specific terminal symptoms. Inducing or trigger factors are not clarified in almost of the cases. Mechanisms or causes of death could not be defined clearly. We concluded that careful heart examination with detailed clinical history under the appropriate postmortem investigation system is only effective approach for the true mechanism and cause of death.
