Background: The purpose of this study was to document the incidence and clinical characteristics of patients with tuberculosis (TB) in combat and auxiliary police, living in a group, in Korea where the incidence rate of active TB in a general population is higher than in Western countries. Materials and Methods:We retrospectively reviewed the medical records of all tuberculosis patients diagnosed at National Police Hospital from January 2002 through December 2004. Results:In 2002-2004, a total of 156 cases of tuberculosis were identified with the mean (Standard deviation) age of 20.6 (±1.0) years. Of these, 134 (85.9%) patients were registered as new cases, 11 (7.1%) as relapse, 2 (1.3%) as failure, 5 (3.1%) as treatment-after-default cases whereas 4 (2.6 %) patients were not included in any categories. Average annual new TB rate and smear-positive TB rate were 86.5/10^(5) and 17.4/10^(5) person-years, respectively. In 12 of 31 smear-positive cases, time from onset of symptoms to diagnosis was more than 30 days. Two multidrug-resistance TB cases were identified and two suspected outbreak episodes of TB had occurred during 3 years. Conclusion:There was no statistically significant difference in the incidence rate of new cases of TB between the general population aged 20 to 29 years and combat and auxiliary police in Korea. 배경 : 국내 결핵의 발생은 감소 추세에 있으나 여전히 후진국형 발생양상을 보이고 있다. 특히 집단생활을 하는 젊은이들에서 발생하는 결핵의 유행이 간헐적으로 알려지고 있어 우려를 낳고 있다. 이에 저자들은 최근 전경대원의 결핵 발병 양상에 대해 알아보고자 본 연구를 시행하였다. 재료 및 방법 : 2002년 1월부터 2004년 12월까지 3년간 경찰병원에서 결핵 진료를 받은 전경대원의 의무기록을 후향적으로 분석하여 연도별 결핵 신환발생률, 도말양성결핵 신환율, 진단 지연, 집단발병, 다제내성결핵을 조사하였다. 결과 : 연도별 결핵 신환자 수(10만명당 발생추정치)는 2002년 50명(83.6명), 2003년 42명(83.7명), 2004년 42명(93.5명)이었고 도말양성 폐결핵 신환자 수는 2002년 10명(16.7명), 2003년 11명(21.9명), 2004년 6명(13.4명)이었다. 3년간 도말양성 폐결핵 환자는 31명이 있었고 그 중 12명은 호흡기 증상 발생 30일이 지나서 진단을 받았다. 다제내성 결핵은 2명이 있었으며 결핵의 집단발병이 의심되는 사례는 2차례 있었다. 결론 : 전경대원과 20-29세 연령군 일반인의 결핵 신환발생률, 도말양성 폐결핵 발생률의 통계적으로 유의한 차이는 없었다.

Virus associated hemophagocytic syndrome is characterized by a benign generalized histiocytic proliferation with marked hemophagocytosis associated with systemic viral infectioin. The syndrome is a non-neoplastic, potentially reversible process and manifested fever, severe constitutional symptoms, hepatosplenomegaly, and lymphadenopathy, and characterized by laboratory findings of pancytopenia, hemophagocytosis and abnormal liver function test and coagulopathy. Immunosuppressive and cytotoxic therapy are contraindicated because of increasing risk of fatal outcome. The authors experienced three cases of virus associated hemophagocytic syndrome diagnosed by clinical features, bone marrow aspiration and lymph node biopsy. All cases had higt fever, hepatosplenomegaly and lymphoadenopathy and showed granulocytopenia in peripheral blood and phagocytized histiocytes in bone marrow. The brief review of the literatures was made.

The separation of rare earths minerals is verb difficult because of their similar chemical properties. The rare earth minerals are used as the mixed rare earth minerals or the misch metal without separation to each element. However, the high purity rare earths are recently produced commercially to each element so they there are used as the materials for high tech. Based on the characterization results for the raw minerals, we have developed a combined process containing gravity seperation, magnetic severation and flotation. The result obtained from this study is monazite concentration of TREO grade 69.11% and Recovery 56.02%.

Severe head injury is associated with a stress response that includes hyperglycemia, which has been shown to worse outcome during cerebral ischemia. To better define the relationship between head injury and hyperglycemia, admission glucose level were analyzed in 150 head injured patients from January 1995 to December 1995. Our retrospective study demonstrated a higher glucose level in patients with low Glasgow Coma Scale(GCS) score, especially at 3-5 GCS score, compared to those with high GCS scores. Also a higher glucose level was noted in patients with vegetative state and dead than in those with good recovery and moderate disability. Hyperglycemia(serum glucose level≥200mg%) was associated with decreased level of consciousness and a poor outcome. We conclude that admission hyperglycemia is a significant indicator of severity of injury(p<0.001), but not significant predictor outcome from head injury. After controlling for the influence of the GCS score, glucose levels do not have an independent effect on outcome.

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.

Diagnostic peritoneal lavage is a accurate and safe method confirming the intraabdominal injury with head trauma, unstable multiple injuried patients. But the development of imaging technique and the trend in noninvasive diagnostic value is decreasing now. In the emergency room, the emergency physicians are required the rapidity and accuracy in intial assessment and the decisions for the operation or not. So emergency physicians have been investigating the diagnostic method for intraabdomial injury that is more rapid, safe and accurate. Many diagnostic tools are developed and now accepted and used widely, among them the diagnostic peritoneal lavage is still the best method for unsatble or head injuried patients. But the positive diagnostic criterias are variable by many authors and still remain imperfectly. So our study was reviewed by medical record of patients who were undertaken the diagnostic peritoneal lavage for the diagnosis intraabdominal injury and statistical analysis was done compared with many criteria of red blood cell and white blood cell for the more accurate way. A retrospective study of diagnostic peritoneal lavage was done of 90 patients with blunt abdominal trauma during 2 years from January, 1996 to December, 1997 and summerized our experience. The results were as follows; 1) There are 73 males and 17 females in sex. The most common type of injury was the traffic accident. 2) With many variable criteria of RBC and WBC, the accuracy and the false positive and false negative were not different in statistical results. The average accurracy was 80.1%. 3) The operations were done in 30(33.3%) cases, and the most frequent injuried organ was the small bowel, 20 cases(66.7%).
