Objectives : This study was conducted to evaluate the reliability and the validity of the Korean version of the Scale to Assessment Unawareness of Mental Disorder (SUMD-K). Methods : The subjects were 55 schizophrenic patients between ages of 26 and 58 who were recruited from the psychiatric unit of the university hospital and the out-patient clinic. The SUMD-K and insight scale of PANSS were applied to the patients. Results : The range of inter-rater (Spearman's rho) of the general items of SUMD-K were .97-.98 on the current illness and .58-.98 on the past illness. The correlation coefficient between the sum and the general items of the SUMD-K showed high scores. The concurrent validity between SUMD-K and insight item of PANSS was high (scores between .59-.96). However,the reliability and the validity of the attribution items of symptoms showed low scores compared to the current symptoms. Conclusion : The SUMD-K was confirmed in its reliability and validity. It can be a useful clinician-rating scale for evaluating insight in schizophrenic patients as well as patients with other neuropsychiatric conditions.

혈액질환 가운데 결핵 발생이 증가한다고 알려진 것은 호지킨 림프종을 포함한 림프증식성질환 그리고 모양세포성 백혈병 등이 있다. 또한 동종 골수이식을 받은 환자에서도 결핵은 증가한다고 알려져있다. Kaplan 등은 골수구성 백혈병 환자에서 결핵 발생이 증가한다고 보고하였다. 그러나 골수구성 백혈병 환자에서 결핵의 발생이 증가하는 이유에 대해서는 아직까지 정확하게 밝혀지지 않았다. 저자들이 2년 동안 후향적으로 조사한 180명의 성인 골수구성 백혈병 환자들 가운데 결핵이 발생한 환자는 4명이었고, 발생 부위는 모두 림프절이었다. 결핵은 골수구성 백혈병의 특정 아형에만 국한되어 발생하지 않았지만, 50%에서 FAB 분류에 의한 M4였다. 림프절이 종대된 골수구성 백혈병 환자에서 특히, 결핵의 유병율이 높은 나라에서는 결핵성 림프절염도 감별진단에 포함시켜야 한다. During the neutropenic phase, leukemia patients receiving chemotherapy are prone to bacterial and, fungal infections; occasionally mycobacterial, viral and protozoal organisms may also cause infections. Mycobacterium tuberculosis infection was reported very rarely in these patients. This report describes four patients with M. tuberculosis infection identified from 185 adult patients who were diagnosed myelogenous leukemia between January 2003, and December 2004. There was no patient with M. tuberculosis infection from 44 lymphoid leukemia and 11 acute biphenotypic leukemia patients. Sites of infection were all lymph nodes. Three among four patients were presented with lymphadenopathy at initial diagnosis of leukemia, and the other one presented with lymphadenopathy after induction chemotherapy. There was no patient presented with lymphadenopathy during the neutropenic phase. Tuberculous lymphadenitis was presented in a patient with three acute myelogenous leukemia (FAB class 2 M4, 1 M2) and a chronic myelogenous leukemia, accelerated phase. An acute myelogenous leukemia patient had a leukemic cell and tubercle bacilli in the same lymph node. Tuberculosis should also be included as a differential diagnosis in myelogenous leukemia patient with lymphadenopathy, especially in the countries in which the disease is endemic.

Coproporphyrin 簡易 定量法의 改善에 關한 硏究

李昌和,宋東彬,車喆煥 고려대학교 의과대학 1984 고려대 의대 잡지 Vol.21 No.1

Rimington (1971) developed a satisfactory method for quantitative determination of urinary coproporphyrin (CP), which is essentially needed for diagnosis of lead poisoning in suspected persons. But it is found to be unsuitable for a mass screening because it is Iaborious and complex in its procedures. Soulsby (1974) modified the method into a simple and convenient one by reducing the steps in extraction procedure. In spite of its simplicity and usefulness for screening purpose, aythor experienced that CP determination by the method was inconsistent and erroneous. Thus, it was not satisfactory and acceptable if accurate determination of CP is needed as in screening test for lead poisoning. The present study was performed to find a simple and accurate method that is applicable for the quantitative determination and mass screening by modifying Soulsby’s method. The results were as follows: 1. The amount of CP extracted with diethylether was shown to be highly dependent on urine pH, when extraction was performed one time instead of three times. The optimal pH was 5.4 where 98% of CP was recovered with one time extraction. 2. When the diethylether layer was washed with distilled water, it was possible to avoid interference in UV-spectrophotometry caused by contaminated organic materials. 3. With modification as above, average recovery rate of CP from urine was 99.5% with a coefficient of variance 2.1% on vaiidity test. 4. The results suggested that Soulsby’s method can be improved to a method with both simplicity and accuracy by simple modifications, i.e., one time extraction with adjusting the urine pH to 5.4 and washing the diethylether later containing CP with distilled water.

목적 : 수부의 중수지 관절 탈구의 관혈적 정복이 필요했던 예에서는 정복을 방해하는 구조물에 대해 분석하고 도수 정복이 가능했던 예에서는 성별 및 탈구 형태에 따른 특성에 대해 알아보고자 하였다. 대상 및 방법 : 총 27예의 수부 중수지 관절 탁구 환자 (무지 11예, 이지 14예, 소지 2예)를 대상으로 연구하였다. 탈구된 중수지 관절의 정복을 방해하는 해부학적 구조는 수술시에 확인을 하였으며, 도수 정복이 가능하였던 예들에서도 연령과 손상된 구조물, 그리고 최종적인 임상 결과를 평균 7개월간 추시 관찰하였다. 결과 : 무지 중수지 관절의 탈구 11예 중 파열된 전방 관절낭, 수장판과 단무지 굴건의 파열을 동반한 복합 탈구가 8예 있어 관혈 정복을 시행하였으며, 2예에서만 도수 정복이 가능하였다. 관절염이 있던 1예는 관절 유합술을 시행하였다. 다른 수지의 중수지 관절의 탈구는 Kaplan의 개념에 따라 탈구를 수술 정복하였고 파열된 수장판을 복원하였으며, 1예에서 수술시 표재 중수 횡인대만의 절개와 이완으로 정복할 수 있었다. 소지 중수지 관절 탈구의 2예에서 파열된 요측 측부인대가 수술시 관찰되었고 이를 복원하여 수지의 불안정성을 예방하였다. 이들의 최종 결과는 특별한 운동 제한이나 불안정성 없이 좋은 결과를 보였다. 결론 : 적절한 국소 마취하에 도수 정복을 1~2회 시행할 수 있지만 단순 정복이 가능한 탈구가 부적절한 견인으로 정복이 불가능한 복합 탈구로 진행할 수 있다. 그리고 복합 탈구는 대부분 관혈적 정복이 필요하기 때문에, 정복 방해 구조물에 대한 충분한 이해와 적절한 조치가 필요하다. Purpose : To analyse the obstacles to prevent the reduction for dislocation of the metacarpophalangeal (MP) joints of the hand and evaluate the relationship between the sex and dislocation type in closed reduction case. Materials and Methods : Total 27 cases of MP joint dislocation of the hand (11 cases of thumb, and 14 index and 2 little finger) were reviewed retrospectively. The anatomical structures to prevent the reduction were confirmed at operation and the cases which were reduced immediately were also analysed for their ages and differences of damaged structures, and finally their complications or outcome were reviewed for average 7 months after reduction. Results : In 11 cases of thumb MP joint dislocations, the complex dorsal dislocations in which the protruded metacarpal neck was caught by buttonhole of torn anterior joint capsule, volar plate and FPB were reduced by open method in 8 cases, and closed reduction was done in 2 cases but one old case required arthrodesis. In other finger MP joint dislocations, the Kaplan's concept to prevent the reduction was confirmed. But reduction of torn volar plate and incision of transverse metacarpal ligament were sufficient to reduce the dislocation with gentle longitudinal traction during the operation. In two cases of little finger MP joint dislocation, the ruptured radial collateral ligaments were noted after open reduction and it must the repaired to prevent the finger instability later. Their overall end results were good without any significant restriction of MP joints motions and finger instabilities. Conclusion : One or two times of closed reduction with proper local anesthesia could be tried, but simple reducible dislocation can be converted to complex irreducible ones by the inappropriate traction method, and so proper reduction technique by closed or even in open way is important with the knowledge of anatomical obstacles to prevent the reduction of the metacarpophalangeal joints.

N/A Background/Aims: It is suggested that diffuse esophagenl spasm (DES), nutcracker esophagus (NUT), and hypertensive lower esophageal sphincter (HLES) could be re-classified together as a spastic esophageal motility disorder of similar clinical background. However, there were no studies to evaluate the pathophysiological characteristics of these motor abnormalities. The aim of the study was to evaluate the changes of esophageal motor function depending on the different types of the bolus (water vs semi-solid bolus). Methods: Twenty-one healthy subjects and 42 subjects with primary esophageal motility disorders (4 DES, 12 NUT, 5 HLES, 12 nonspecific esophageal motility disorders, 9 normal) underwent a perfusion manometry with a low compliance pneumo-hydraulic capillary infusion system. Consecutively, each patient had l0 swallows of water and 10 swallows of Jello, 5 ml each. Results: In the healthy controls, the Jello swallow showed an increased amplitude and duration of distal esophageal contraction, and the velocity of peristalsis was decreased (p<0.05). Among all patients diagnosed by manometry with the water swallow, 2 cases diagnosed with HLES (40%) and 4 with NUT (33%) were changed to a diagnoses of DES after the Jello swallow. Moreover, HLES was found in 1 patient with DES (25%) and in 6 patients with NUT (50%). Conclusions: Semi-solid bolus swallows increase the contractile force of the esophagus more than water swallows. A conventional manometric diagnosis could be changed to a different spastic motility disorder of the esophagus after a semi-solid bolus swallow. It is suggested that DES, NUT, and HLES can be considered as a spectrum of spastic esophageal motility disorders sharing a similar pathophysiology.
