The purpose of this study was to compare the geometric displacement between the lateral cephalometric radiograph and photograph. For the present study, 52 subjects with Angle Class I occlusion and no severe skeletal discrepancy were selected. The Head Posture Aligner and the standardized camera set up were adopted to obtain photographs and radiographs in a standardized manner. Six metal markers were placed on the subject's right side face representing Glabella (G), Zygoma (Zy), Philtrum (Ph), Soft tissue Gonion (Go'), Soft tissue Pogonion (Pog'), Soft tissue Menton (Me') before taking the lateral cephalometric radiograph and photograph. The 14 linear, 28 angular, and 5 area differences were measured after superimposition of the radiograph and photograph using nose and upper lip as a reference on the Image Analyzer. The paired t-test and the percentage of differences were used to compare the geometric displacement of metal markers between the lateral cephalometric radiograph and photograph. Through the statistical analysis, the following results were obtained. 1. When the linear measurements were compared between the lateral photograph and radiograph, the measurements related to Zy and Go' except Zy-Me' and Go'-Ph showed significant differences on both images. 2. On the angular comparison, the overall measurements except Me'-Ph-Pog', Ph-Pog'-Me', Ph-Me'-Pog', G-Me'-Ph, Me'-G-Ph. Ph-Go'-Pog', Go'-Zy-Me' and G-Go'-Me' showed significant differences on both images and especially the measurements related to Zy showed greater difference. 3. In area measurements, the overall measurements except G-Zy-Go' showed enlargement of the radiograph. 4. On the superimposition of the radiograph and photograph, the measurements related to the profile tended to be well matched. However, Zy on the lateral radiograph tended to be displaced downward and backward more than Zy on the photograph. Furthermore Go' on the lateral radiograph tended to be displaced upward and backward more than Go' on the photograph. The results suggested that the precise superimposition between the lateral cephalometric radiograph and photograph was not feasible due to differences in enlargement.

Background : Pneumocytitis cainii pneumonia (PCP) can occur in immunocompromised hosts especially such as AIDS or cancer patients. Although recent research had focused on PCP in AIDS patients, few studies have described the clinical presentations of PCP in recipients of stem cell transplantation (SCT). We evaluated the clinical manifestations of PCP in SCT patients admitted at St. Mary's hospital, Seoul, Korea. Methods : The medical records of 17 PCP patients undergoing SCT between Feb. 1998 and Feb. 2000 were reviewed. The diagnosis of PCP was confirmed through the demonstration of Pneumocytitis cainii via either cytology of brochoalveolar lavage (BAL) or histological technique of lung biopsy. CMV disease and CMV infection were confirmed by BAL culture and antigenemia respectively . Results : Seventeen patients were all recipients of allogeneic SCT and 7 of 17 patients were performed non-sibling SCT. Patients presented with symptoms including brief period (4 ∼23 days) of fever (76%), dyspnea (70%), cough (64%), and signs such as rare(58.8%), Sixteen patients (94%) had been receiving immunosuppressive agent such as cyclosporine A (64%) or Fk506 (35%) without PCP prophylaxis. Eleven patients (64%) were treated with corticosteroid with mean dose of 16 mg/day prednisolone and mean duration of 4.6 months after post-SCT period. Twelve patients were co-infected with CMV. Another co-infected miCroorganisms were Pseudomonas aeruginosa, Mycobacterium tuberculosis, herpes simplex virus, parainfluenza virus, Average duration of treatment with trimethoprim-sulfamethoxazole (TMP/SMX) was 21 ±9 days. Four patients died, and three of them were related with PCP. Conclusion : PCP developed frequently in patients who were taking immunosuppressive drug due to graft versus host disease or were not taking TMP/SMX prophylaxis. High risk patients showing fever, cough, or dyspnea should be considered to take early bronchoscopic intervention for detection of PCP. When treat for PCP, it also be considered to the possibility of coinfection such as CMV. (Korean J Infect Dis 33:273∼279, 2001)

Coccidioidomycosis is a fungal infection that results from inhaling the airborne arthroconidia of the Coccidioides species. It is an endemic disease in the southwest part of North America and rarely diagnosed in Korea. As tourism to endemic areas and the number of immunocompromised patients have been increasing, the incidence of this infection has increased in non-endemic areas. Treatment is usually successful with antifungal agents; however, recurrence is common. It is difficult to decide when to discontinue the antifungal treatment especially in non-endemic areas where doctors are not familiar with the disease. We report a case of recurrent coccidioidomycosis manifesting as osteomyelitis after the treatment of the patient for disseminated coccidioidal infection. The complement fixation test was a useful tool for the assessment of patient response and to evaluate suspected recurrence.

본 연구는 한국인의 치아형태에 적합한 브라켓 베이스를 만들기 위해 임상 치관의 순, 협측 곡률을 3차원적으로 계측하여 치관의 곡률 자료를 얻고자 하였다. 정상적인 해부학적 형태를 가지는 구강모형 30쌍을 3차원 디지털 모델로 제작한 후, FA점을 기준으로 수평 기준면과 수직 기준면을 설정하였다. 이 기준면에 대한 치면의 곡선을 형성한 후, 곡률을 이차방정식의 계수로 표현하였다. 수평면과 수직면의 곡률과 FA점을 기준으로 근심과 원심, 치은측과 교합면측의 곡률을 측정한 결과, 상악견치와 상악 제2소구치 외에는 남녀간 치면 곡률의 유의한 차이가 없었다. 하악 측절치, 상악 견치, 상하악 제1, 2소구치와 제1대구치에서 근원심 또는 치은교합면측 치면 곡률의 유의한 차이가 관찰되었다 (P < 0.05). 본 연구에서 얻어진 순, 협측 치면의 곡률 자료는 한국인의 치아 형태에 적합한 Straight Wire Appliance 개발의 기초 자료로 활용될 수 있다. Objective: This study was performed to investigate the labio/buccal clinical crown curvatures of Korean permanent teeth and to obtain the curve-ratio data in an attempt to fabricate bracket bases fit for each individual Korean permanent tooth. Methods: Three-dimensional digital models were made from 30 sets of dental casts with normal anatomic structures. According to the FA points, horizontal and vertical reference planes were established and lines were drawn on the tooth surfaces in reference to these planes. The curvature was expressed as the coefficient of a quadratic equation. Lines mesial, distal, gingival and occlusal to the horizontal, vertical reference planes and the FA point were drawn. Results: The curvature measured for each line revealed that there are no significant differences between male and female, except for maxillary canines and maxillary second bicuspids (P > 0.05). There were notable differences in the mesio-distal or gingivo-occlusal curvatures among the mandibular lateral incisors, maxillary canines, maxillary and mandibular first and second bicuspids and first molars (P < 0.05). Conclusions: The labial & buccal crown curvatures of teeth in Korean normal occlusion were measured on the mesial and distal, gingival and occlusal sides respectively in this study. Based on these data, a SWA can be developed to fit the individual features of Korean tooth crowns.
