A variety of materials and procedures such as sinus floor elevation, sinus-lift graft, inlay bone graft using Le Fort I osteotomy, and onlay graft have been used to create adequate bone volume in the maxillary sinus for placement of endosseous implants in the posterior atrophic maxilla. Because of the frequent lack of bone in the posterior maxilla, sinus lift procedure has become a commonly practiced treatment modality. The 138 endosseous implants of 36 patients with sinus augmentation procedures performed in Korea University Hospital from January 1991 to December 1998 were summarized and analysed. The result of this study were as follows : 1. Age ranged from 39 to 57, with a mean of 50.7. 2. The mean survival rate for 138 implants with maxillary sinus lift procedure was 80.4%. 3. There was no corelationship between the fixture length, width and the survival rate. 4. The result showed that the healing period for 8-12 months was necessary if the residual alveolar bone height was less than 5mm. 5. Autogenous iliac corticocancellous block graft showed the most favorable survival rate(95%).

Purpose : This study was carried out to evaluate the abnormalites of the speeches of the cleft patients and compare the results of the speech evaluations of a speech pathologist with those of parents. Materials and Methods: Eleven cleft patients' parents were questioned about their children's speech and then the speeches of the cleft patients were evaluated by a speech pathologist and their results were compared with those of parents. Results : Nasal emission was noted in twenty percent of patients, with thirty percent demonstrating hypernasality and all demonstrating no hyponasality and aspirate. And twenty percent of patients show hoarseness. There was no statistically significant difference in the sensitivities to nasal emission between the speech pathologist and parents (p>0.05). However the speech pathologist is more sensitive to hypernasality than parents(p<0.05).

동일한 환자에서 조혈모세포이식 전후의 호중구감소 기간 중 감염양상에 대한 비교연구 : 중심정맥관 관련 패혈증을 중심으로 Based on Central Venous Catheter Related Septicemia

류재호,노규태,이영석,이영호,권혁찬,김재석,김효진,이영민,박혜원,박근희 대한조혈모세포이식학회 2002 대한조혈모세포이식학회지 Vol.7 No.1

연구배경: 동일한 환자를 대상으로 조혈모세포이식 전 일반 병실에서의 관해유도 항암제치료 및 강화요법으로 인한 호중구감소 기간의 감염양상과 고용량 항암제치료 후 무균실에서의 조혈모세포이식 시 호중구감소 기간의 감염양상을 중심정맥관 관련 패혈증을 중심으로 비교 연구함으로써 효율적인 감염관리지침을 마련하고자 하였다. 대상 및 방법: 1999년 1월부터 2001년 7월까지 2년 7개월간 동아대학교병원 일반병실에서 악성혈액질환으로 항암제 치료를 받다가 조혈모세포이식을 시행받았던 22명을 대상으로 중심정맥관 관련 패혈증의 형태를 비교분석하였다. 결과: 대상 환자들의 일반병실과 무균실에서의 입원기간은 각각 32±13일, 33±19일, 호중구 감소기간은 15±12일, 17±18일, 호중구 감소기간의 발열 횟수는 14회, 14회로서 입원병실의 종류에 따른 차이는 없었다. 환자들의 중심정맥관 사용일수는 일반병실에서 29일(7~545일), 무균실에서 100.5일(25~606일)이었으며, 총 사용일수는 각각 1,515일, 3,250일로서 무균실에서의 중심정맥관 사용일수가 의미 있게 길었다(P=0.001). 중심정맥관 사용 일수에 대한 감염률은 각각 5.28/1,000일, 3.08/1,000일로서 일반병실에서 그 빈도가 높았으나 통계적 유의성은 보이지 않았다(P=0.141). 결론: 중심정맥관 삽입 후 일반병실에서 항암제 치료를 받던 환자가 조혈모세포이식을 위하여 무균실에 입원하는 경우, 중심정맥관을 교체하는 것이 감염관리를 위하여 바람직할 것으로 생각된다. Background: We compared the incidence of central venous catheter (CVC) related septicemia during neutropenic period in the same patient, which developed following chemotherapy for remission induction and consolidation, or hematopoietic stem cell transplantation (HSCT). Methods: We retrospectively reviewed the medical records and laboratory data of 22 patients with hematologic malignancies who received anticancer chemotherapy followed by HSCT at Dong-A University Hospital between January, 1999 and July, 2001. We investigated the duration of hospitalization, duration of neutropenic period, duration of catheterization, microbiologically documented organisms and incidence of CVC related septicemia. Results: The data in general ward (before HSCT) and laminar air flow room (after HSCT) were as follows: duration of hospitalization was 32±13 days and 33±19 days, duration of neutropenic period was 15±12 days and 17±18 days, median duration of catheterization was 29 days (7~545 days) and 100.5 days (25~606 days) (P=0.001), and incidence of CVC related septicemia was 5.28/1000 days and 3.08/1000 days, respectively. In the CVC related septicemia, the most common etiologic organism was coagulase negative staphylococcus. Conclusion: We suggest that the exchange of CVC before admission to laminar air flow room could decrease the incidence of CVC related septicemia in HSCT recipients.

Lupus vulgaris, which is a progressive form of postprimary tuberculosis in patients with a moderate to high degree of immunity and tuberculin sensitivity, is the most common, most serious, and most variable type of cutaneous and mucous membrane tuberculosis. Domonstration of M.tuberculosis directly or in culture in some of these eruptions can be difficult. It is essential to demonstrate the presence of M.tuberculosis in a clinical sample for a definitive diagnosis of tuberculosis. With the discovery of the polymerase chain reaction (PCR), the DNA diagnostic approach for infection has developed in a short period. With the dual purpose of definitive and rapid diagnosis of tuberculosis, this study examined the usefulness of a nested PCR for detection of M. turberculosis. Compared with a single-step PCR, the two-step PCR was able to enhance sensitivity approximately 1,000-fold on the basis of bacterial counts and DNA quantity. We concluded that two-step nested PCR appeared to be the most useful PCR protocol for early and sensitive diagnostic method detecting M.tuberculosis in acid-fast stain negative specimens.

Objective: This study was designed to evaluate diagnosis and complication, prognosis during clinical study of cases of intrauterine fetal death. Methods and materials: This is a clinical study of 56 cases of the intrauterine fetal death among 8064 deliveries at Seoul Sunchunhyang university hospital during 5 years from January, 1994 to December, 1998. Results: The incidence was 0.7%. The age distribution of mothers was 18 - 44 years and was highest in the 25 - 29 years range(46.4%). The parity was the most highest in the nulliparous group(51.8%). The most common gestational weeks was 20 - 28 weeks gestational period(46.4%), and most common presentation was cephalic(73.5%). The most common weights of the intrauterine fetal death was from 5,00gm to 1,000g(48.2%). The mode of the most common delivery was the induction of delivery(57.2%). The etiologic factors were: unknown(42.9%), preeclampsia(17.9%), chorioamnionitis(14.3%), congenital anomaly(12.5%), abruptio placenta(7.1%), cord complication(3.6%), placenta previa, death of one for twin. There were 2 cases of maternal complication(DIC, Uterine atony). Conclusion : Intrauterine fetal death should be diagnosised early and treated properly to reduce risk of the maternal complication.

It is essential to identify and localize the maxillary sinus septa in maxillary sinus lift procedure to prevent tearing of sinus mucosa. The variations and frequency of bony septa in the maxillary sinuses were studied prospectively by means of computed tomography. PATIENTS AND METHODS: The presence and morphology of the septa in the maxillary sinuses were studied in 80 non-selected adults. RESULTS:CT examinations of 160 maxillary sinuses were done. The septo were observed in patients.

Background : In recent years, gonorrhea has been panedemic and remains one of the most commom STDs in the world, especially in developing countries. Objective & Methods: For the detection of a more effective therapeutic regimen and assessing the prevalence of PPNG, we have been trying to study the patients who have visited the VD Clinic of Choong-Ku Public Health Center in Seoul since 1980 by means of the chromogenic cephalosporin method. Results: In 1996, 139 strains of N. gonorrhoeae were isolated, among which 53(39.0%) were PPNG. Conclusion: Our results suggests that after a peak of 74.3% in 1993, the prevalence of PPNG in Seoul is gradually declining.
