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.

CNPA는 기존의 폐질환 및 폐절제술로 인해 국소방어기전에 저하가 있거나 비특이적 전신면역상태저하를 갖고 있는 환자들에게서 주로 발생하는 만성적인 공동성 폐질환이다. 현재까지 우리나라에서는 CNPA의 보고가 없는 상태이고, 저자들은 최근 조직학적으로 진단된 CNPA 2예를 경험하였기에 보고하는 바이다. 저자들이 경험한 CNPA 환자들은 만성알코올 중독 및 기관지확장증과 같은 기저질환과 폐절제술을 받은 병력이 있었다. Aspergillus가 폐실질을 침윤하고 있는 조직소견과 조직배양에서 Aspergillus가 검출되어 조직학적 진단이 가능하였고, amphotericin B의 정주요법 및 경구 itraconazole 투여와 폐절제술 등으로 성공적으로 치료되었다. 아직 많은 임상의들에게는 낯선 질환인 CNPA의 치료성적은 환자의 동반질환 및 CNPA 자체의 중증도, 진단과 치료 시작의 지연 등에 의해 크게 좌우되므로 만성적으로 진행하는 공동성 폐병변을 갖고 있는 환자에게서 CNPA를 감별하는 것이 중요하다. Chronic necrotizing pulmonary aspergillosis (CNPA) is a chronic cavitary form of pulmonary aspergillosis. Dozens of CNPA cases have been reported in patients with systemic immunologic dysfunction or altered local defense mechanism from preexisting pulmonary disease. Review of literatures revealed that no CNPA cases have been reported in Korea yet. We experienced two cases of CNPA proven by lung biopsy. A 53-year-old alcoholic male in poor nutritional state was admitted with generalized weakness and weight loss. Chest CT revealed a cavitary nodule surrounded with ground-glass attenuation. CT-guided fine needle aspiration and biopsy was done. The biopsy specimen demonstrated dichotomously branching septated hyphae consistent with those of Aspergillus sp. Another case was a 39-year-old man with bronchiectasis who was admitted with persistent hemoptysis. He had a past history of pulmonary tuberculosis. A parahilar lesion with intracavitary soft tissue mass was incidentally detected in high-resolution GT. Left lingular segmentectomy was done due to uncontrolled hemoptysis and CNPA was histologically diagnosed. Both patients were successfully treated with intravenous amphotericin B followed by oral itraconazole. Even though CNPA is unfamiliar to most clinicians, it should be included in differential diagnoses of chronic progressive cavitary pulmonary lesion, especially in patients with immunologic dysfunction.

김형렬,원종욱,송재석,김현수,김치년,노재훈 大韓産業醫學會 2003 대한직업환경의학회지 Vol.15 No.2

목적: 본 연구는 상지 근골격계 질환의 유병율이 높은 집단으로 알려진 VDT작업자를 대상으로 이들의 근골격계 통증을 정량화하고, 정량화된 통증점수를 종속변수로 하여, 이와 관련성을 갖는 작업요인, 사회심리적 요인을 파악하고자 하였다. 방법: 서울지역에 위치한 1500병상 규모의 대학병원에 근무하고 단말기 작업을 주로 수행한다고 알려진 부서에 대해 병원내 안전관리과와 협의를 거쳐 163명을 연구대상으로 선정하였다. 이중 138명이 설문에 참가하였고, 이들을 최종 연구대상으로 하였다. 설문지를 가지고 연구변수를 측정하여, 나이, 근무연수, 가사노동의 정도 등의 인구학적 변수와 직무스트레스 및 사회적지지, 근골격계 증상, 통증의 양상 등을 조사하였다. 분석방법은 일반적 특성 및 작업특성, 통증의 양상을 성별에 따라 파악하였고, 통증점수의 타당성을 검정하기 위해, 통증점수의 구성요소와 통증점수를 시각적 상사척도와 상관성 검정을 시행하였다. 통증점수를 종속변수로 하고 직무요구도, 직무재량도, 동료의지지, 상사의지지, 여러작업환경특성, 인구학적 특징 등을 독립변수로 하여 다중회귀분석을 시행하였다. 결과: 첫째 통증의 정량화를 위해 사용한 통증평정지수는 시각적 상사척도와의 상관관계가 높은 것으로 나타나, 어느 정도의 타당성을 지닌 방법으로 해석할 수 있었다. 둘째, 이 통증 점수를 종속변수로 하여, 관련요인 분석한 다중회귀분석에서 직무요구도가 높을수록 통증의 정도가 높고(p<0.01), 여성일수록 남성에 비해 높은 통증점수를 보였다(p<0.01). 결론: 근골격계 질환의 높은 유병율을 보이는 집단의 경우, 이들의 증상 유무만을 가지고 관련요인을 분석하는 방법을 사용하기 어렵다. 따라서 이런 경우, 통증을 정량화하여, 다양한 관련요인을 찾으려는 노력이 필요하며, 본 연구에서 사용한 통증평정지수는 타당성을 지닌 정량화 방법이라고 여겨진다. 또한 본 연구에서는 직무요구도가 높을수록, 여성일수록 높은 통증점수를 보였다. Objectives: This study was designed to quantify symptoms in the upper extremities and to identify the pain related factors among hospital workers using video display terminals. Methods: The subject-group consisted of 138 employees working at a hospital using video display terminals. A structured questionnaire was used to estimate the participants' general characteristics, and job contents. Job stress was measured using Karaseks JCQ(Job Content Questionnaire). Pain in the upper extremities was identified according to the NIOSH symptoms survey criteria. Quantification was measured using Kim Chul's method. Pearson's Correlation analysis was used to identify validity in quantification. VAS(visual analog scale) was used to compare with this method. Multiple regression analyses elucidated the relationship between quantified pain and various work factors, such as job stress. Data were analysed with SAS 6.12 program. Results: First, in quantification using Kim Chul's method, the correlation between modified PRS(pain rating score) and VAS was extremely high by 0.60(P<0.01), indicating the high validity of PRS. Second, the groups of high job demand, high job control, and females were related to an increased pain level. Conclusions: These results suggest that the self pain assessment method, PRS, is valuable and useful in analyzing occupational musculoskeletal symptoms. High demand, job control and gender may influence the levels of pain. Prospective studies about musculoskeletal disorder are required.

목적 : 항암화학요법 중 호중구감소증을 동반한 발열이 발생하는 암환자들을 치료하기 위한 다양한 항균제와 여러 가지 방법들이 시도되고 있는 가운데, 합병증과 사망률의 발생가능성이 적은 저위험군 환자들을 대상으로 초기 72시간동안 정주 항균제를 투여한 이후 경구 항균제로 전환하는 요법의 유용성과 안정성을 평가해보고자 본 연구를 시행하였다. 방법 : 1998년 2월부터 1999년 9월까지 본원에서 항암화학요법 중 호중구감소증과 발열이 발생한 환자들 가운데 기저 암질환이 고형암이거나 림프종이고, 입원당시 패혈증의 증후가 없으며 입원 72시간이내에 해열되고 백혈구수치가 증가 추세인 환자들을 대상으로 하여 72시간 동안 정주 항균제를 투여한 이후 경우 ciprofloxacin 750㎎을 하루 2회씩 투여하여 총 4일간 투여하였다. 모든 환자들은 열이 떨어지고 호중구감소증이 회복될 때까지 입원하도록 하였다. 결과 : 총 38명 환자의 40예가 등록이 되었고, 환자들의 기저암 질환은 고형함이 72.5%, 림프종이 27.5%였다. 입원당시 평균 호중구치수는 156/㎕였고, 호중구수치가 100/㎕미만인 경우는 65%였으며, 호중구감소증이 지속된 기간의 평균은 2.4일이었다. 40예 중 39예가 항균제의 변형이나 추가 없이 호중구감소증과 발열로부터 회복이 되어 97.5%의 성공율(95% 신뢰구간: 86.8-99.9%)을 보였다. 부작용으로 피부발진이 있었던 경우가 한 예 있었는데, 증상이 경하여 경구 항균제를 지속할 수 있었다. 심와부의 동통으로 복용을 지속할 수 없어서 대상에서 제외된 예가 또 한 예 있었다. 결론 : 항암요법 중 호중구감소증과 발열을 동반한 환자들 가운데 저위험군 환자들에서 항균제 72시간정주 이후 경구 항균제로의 전환요법은 효과적이고도 안전한 치료방법이라고 할 수 있다. Background : Oral antibiotic therapy following empirical intravenous antibiotics may be effective and safe for febrile neutropenic patients with lowrisk for complications. Methods : We conducted a prospective clinical trial of oral antibiotic therapy in the patients with neutropenia and fever during chemotherapy for cancer. Underlying malignancies were solid tumor or lymphoma with short duration of neurtropenia and the patients had no evidence of clinically or microbiologically documented infections. Oral ciprofloxacin was given to the patients who lacked signs of sepsis on admission, had a rising tendency of neutrophil count (ANC >100 /㎕ ) at 72 hours, and were afebrile at 72 hours. All patients were hospitalized until neutropenia and fever resolved. Results : A total of 40 episodes of 38 patients were enrolled from February 1998 to September 1999. The mean neutrophil counts on admission were 156/㎕ and the mean duration of neutropenia was 2.4 days. The episodes which had neutrophil count below 100 /㎕ were 26 (65%). Treatment was successful in 39 of 40 episodes (97.5% : 95 % confidence interval, 86.8% to 99.9%). Adverse reactions of oral ciprofloxacin were skin rash and epigastric soreness in two cases, respectively. There were no deaths during the study. Conclusions : For low-risk febrile patients with neutropenia during cancer chemotherapy, switch therapy to oral ciprofloxacin at 72 hours following intravenous broad-spectrum antibiotics is effective and safe,

The purpose of this study was to investigate the inhibitory effect of fluoride in the water and milk on tooth enamel dissolution by commercial beverages. 3 weekold 60 female sprague-Dawley strain were divided into four groups and given the following dosage of fluoride in the drinking water:0,1,5 and 50ppm for six and twelve weeks ad libitum. Upper incisors were prepared for specimen with low speed dental disc.The slabs of each incisors were embedded in unsaturated polyester,polished with #1,200 silicon carbide paper and aluminisilicate powder.Three kinds of beverage were selected for test medium and enamel slabs of rat incisors were dipped for 60 and 120 minutes in each beverage.Surface microhardness was examined before and after dissolution with beverage. All collected data were analyzed using the SAS package.Differences between groups were compared by the one-way ANOVA,Duncan's multiple range test and ANCOVA procedures. Corresponding p-values were considered significant at the values less than 0.05. The obtained results were as follows: 1. Surface microhardness was significantly increased both 6 and 12 weeks groups compared with control group. Surface microhardness of high fluoride groups were also proportionally increased with increasing concentration of fluoride both in the water and milk. 2. There were significant differences of inhibitory effect of surface microhardness after 60 and 120 minutes emersion periods,and both at 6 and 12 weeks group in the veverage B and C,but not appeared in the beverage A. 3. The inhibitory effect of enamel dissolution was higher in the 12 weeks group than 6 weeks group both at the water fluoridation and milk fluoridation. 4. The differences of micro hardness between before and after emersion in the beverages were larger in the milk fluoridation groups than water fluoridation groups.

Quercus variabilis is one of the most important tree species in both utilization of forest resources and management of forest ecosystem in Korea. To obtain the basic information for the establishment of breeding strategy and efficient management of genetic resources, five populations of Q. variabilis from 89 selected plus trees were studied using POPGENE and AMOVA analysis based on DNA markers focussing on the genetic diversity and variation among populations. The overall polymorphic amplicons were 78.6% and levels of genetic diversity within 5 populations were similar each other (Shannon's Index : 0.289∼0.423 [mean 0.366]). The values of total genetic diversity (H_t) and average gene diversity within population (H_S) were 0.265 and 0.239, respectively. The degree of genetic differentiation (G_st : 0.098) was relatively high compared with those of other tree species. Based on the cluster analysis of UPGMA, genetic relationships among 5 populations were not coincided with the pattern of geographic distribution.
