We experienced a 25 year-old male patient with typhoid fever complicated with massive hemoptysis. Pulmonary complication in typhoid fever is very rare and to our knowledge, there has been no report of hemoptysis as a main cause of death with this disease. We herein report a rare case of typhoid fever.

Thick Pb(Zr_(0.52), Ti_(0.48))O₃(briefly, PZT) films are required for the cases of micro actuators and sensors with high driving force, high breakdown voltage and high sensitivity, and so on. In this work, thick PZT films were fabricated by chemical solution deposition process. Total 16 types of samples using thick PZT films with thicknesses, about 1 ㎛ and 2 ㎛, and Pt top electrodes shapes for measuring effective transverse piezoelectric coefficients (e_(31,f)) were prepared using MEMS processes. All samples were characterized by fabricated e_(31,f) measurement system before and after poling process at 125 kV/cm and 150℃ for 10 min. |e_(31,f)| values of samples after poling were higher than samples before poling. Those of 2 ㎛ thick PZT films were also higher than 1 ㎛ thick PZT films. We found that |e_(31,f)| was directly related with {111} to {h00} crystal structures of thick PZT films. And those with narrow electrodes (x₁- x_(0)) as top Pt electrodes were also higher than cases with wide top Pt electrodes in agreement with given equation.

Patients with fixed orthodontic appliances frequently show ineffective plaque control caused by these orthodontic appliances. Although many methods may be helpful in reducing dental plaque formation, optimal mechanical plaque removal and oral hygiene instruction are the most important factors during orthodontic treatment. The purpose of this study was to evaluate the efficacy of an electric toothbrush, with a specially designed orthodontic brush head, compared to a manual toothbrush on periodontal health in patients with fixed orthodontic appliances. Forty patients were randomly divided into two groups, the electric and the manual toothbrush groups, 1 month after attachment of fixed orthodontic appliances. Periodontal status was measured using a plaque index, a gingival index, a bleeding index, a pocket depth and a relative attachment loss, at baseline and after 3 months, 6 months, 9 months, and 12 months. Oral hygiene instruction was given according to the type of toothbrush used. The Braun Oral-B Plak Control with Ortho OD 15-1 brush was used as the electric toothbrush while the Butler G. U. M 124 was given as the manual toothbrush. By comparing between the electric and the manual toothbrush groups, the following results were obtained: 1. In the manual toothbrush group, the gingival and bleeding indices showed no statistically significant differences. but the plaque index was significantly decreased (p<0.001) and pocket depth as well as relative attachment loss were significantly increased (p<0.01). 2. In the electric toothbrush group, the bleeding index, pocket depth and relative attachment loss showed no statistically significant differences, but the plaque and gingival indices were significantly decreased (p<0.001). 3. In the case of the plaque, gingival and bleeding indices, there were no statistically significant differences between the electric and the manual toothbrush groups. On the contrary, in the case of pocket depth and relative attachment loss, there were statistically significant differences between the electric and the manual toothbrush groups: an increase in the manual toothbrush groups unlike the electric toothbrush groups keeping the same state (p<0.05). These findings suggest that an electric toothbrush is useful to orthodontic patients with fixed appliances.

고정식 교정환자에서 치주건강 유지에 대한 전동치솔의 효과

박성준,이기헌,황현식 대한치과교정학회 2005 대한치과교정학회지 Vol.35 No.4

고정식 교정치료 환자들은 구강내 교정장치로 인해 치태제거에 어려움이 있으며 보다 효과적인 치태제거를 위해서는 특별한 구강위생교육 및 치솔질이 필요하다. 본 연구는 고정식 교정치료 환자에서 일반적으로 사용되고 있는 교정용 수동치솔에 비해 전동치솔이 치주건강 유지에 도움이 되는지 알아보기 위하여 시행되었다. 고정식 교정장치에 의해교정치료 예정인 환자 40명을 대상으로 고정식 교정장치 부착 1개월 후 치솔의 종류에 따라 전동치솔군과 수동치솔군으로 연구대상을 임의 구분하고 각각에 맞는 구강위생교육을 시행한 후 3개월, 6개월, 9개월, 12개월 후 치태지수, 치은염지수, 치은출혈지수, 치주낭깊이, 그리고 상대적부착상실을 측정하였다. 전동치솔의 경우 교정용 브러쉬 헤드를 가진 Braun Oral-B 사의 전동치솔을, 수동치솔의 경우 Butler 사의 교정용 치솔을 사용하게 하였다. 수동치솔군의 경우 실험기간 동안 치태지수는 통계적으로 유의하게 감소한 반면 (p<0.001), 치은염지수, 치은출혈지수는 통계적 유의차를 보이지 않았고, 치주낭깊이, 부착상실은 통계적으로 유의하게 증가하였다 (p<0.01). 전동치솔군의 경우에는 치은출혈지수와 함께 치주낭깊이, 부착상실이 통계적 유의차를 보이지 않았으며, 치태지수, 치은염지수는 통계적으로 유의하게 감소하였다 (p<0.001). 한편 치태지수, 치은염지수, 치은출혈지수의 경우 변화양상에 있어 전동치솔군과 수동치솔군 간에 유의한 차이를 보이지 않은 반면, 치주낭깊이와 부착상실의 경우 전동치솔군에서는 처음 상태가 일정하게 유지된 반면, 수동치솔군에서는 치주낭깊이와 부착상실이 증가하는 양상을 나타내었으며 이러한 변화양상의 수동치솔과 전동치솔간 차이는 통계적으로 유의하였다 (p<0.05). 이상의 결과는 고정식 교정장치로 치료받는 환자에서 수동치솔보다 전동치솔이 치주건강 유지에 더 효과적임을 시사하였다.

The purpose of this study was to investigate the possibility of application of microwave energy for the fabrication of polymer/clay nanocomposite. APES/Clay nanocomposites were prepared at 130℃ for 30min with various content of clay by melt-intercalation method under classical and microwave heating source. APES/Clay samples were characterized by the means of X-ray diffractometry(XRD), thermal gravimetric analysis(TGA), and rheometric dynamic analysis(RDA). It was found that intercalated or exfoliated state was obtained in the samples according to the condition of organic modification, clay content, and heating source.

The diagnostic requirements were suggested and explained regarding the systems of differentiation of symptoms and signs in the third year study of standardization and unification of the terms and conditions used for diagnosis in oriental medicine. The systems were as follows : - analyzing and differentiating of epidemic febrile disease - analyzing and differentiating in accordance with the Sasang constitution medicine based on four-type recognition - differentiation of disease according to pathological changes of Chong and Ren channels - standards for diagnosis of women's disease - standards for diagnosis of children's disease - standards for diagnosis of motor and sensor disturbance (-muscle. born, joint, etc.) - standards for diagnosis of neuropsychiatric disease - standards for diagnosis of five sense organ disease - standards for diagnosis of external disease The indivisual diagnosis pattern was arranged by the diagnostic requirements in the following order : another name, notion of diagnosis pattern, index of differentiation of symptoms and signs, the main point of diagnosis, analysis of diagnosis pattern, discrimination of diagnosis pattern, prognosis, a way of curing a disease, prescription, herbs in common use, disease appearing the diagnosis pattern, documents. The standards for diagnosis of each disease was arranged by the diagnostic requirements in the following order : another name, notion of disease, the main point of diagnosis, analyzing and differentiating of disease, analysis of disease, discrimination of disease, prognosis, a way of curing and prescription of disease, disease in western medicine appearing the disease in oriental medicine, documents.

Skeletal cryptococcosis is an uncommon infection. Cryptococcus is a common cause of meningitis and infects 7∼10% of patients with AIDS. As well as AIDS, the infection may be seen in association with leukemia, lymphoma, Hodgkin's disease, sarcoidosis, tuberculosis and diabetes, also in patients on steroid medication. But there is no case report of skeletal cryptococcosis following allogeneic hematopoietic stem cell transplantation. A 40-year-old woman was admitted to the hospital because of low back pain. She had chronic myelogenous leukemia for 2 years and underwent allogeneic hematopoietic stem cell transplantation 8 months ago. She have been treated with steroid and cyclosporine orally because of chronic graft versus host disease. On examination she was afebrile and had posterior lower lumbar tenderness. But, she had no reduced strength of low extremities. Open biopsy was underwent. Histology demonstrated budding, round-to-oval, refractile yeast-like organisms within debris. The results of a lumbar puncture were unremarkable and cerebrospinal fluid culture failed to grow bacteria and yeast. The patient was treated with amphotericin B (1 gram) and AmBisome□ (2.8 gram) over 6 weeks. Three months after cessation of therapy, the patient was doing well.(Korean J Infect Dis 33:298∼301, 2001)
