As the incidence of dermographism in our urticaria clinie is quite high comparing data in other country, we have tried to survey the incidence of ermographism in the general population of Korea using a dermographic tester designed by other author. Total 8g7 healthy persons were included in this study from March J98$ to .December 1983. The study result was summarized as follows, 1. Male to female ratio was 2. 5: 1 and the peak age of the subjects was third(47 8%), fourth and fith decades in ecreasing order, The overall incidence of dermographisrn from the pressure of 48ppg/cm was 4.4% and there were no significa.nt difference in the incidences between male(4, 2%) and female(4 7%) (p>0. 1), and between the different age groups(p>0 l)

Ultrasonographic and radiographic findings in 72 cases of pelvic masses which have been provedhistopathologically were analyzed. The results were as follows; 1. Among 72 cases, 28 cases were uterine massesand 44 cases were adnexal masses. 2. Pathologic accuracies of ultrasonographic diagnosis were 64.3% in uterinemasses, 70.5% in adnexal masses, and 68.1% in all pelvic masses. 3. Plain or IVP findings were not specific indiagnosis and showed secondary mass effects or functional disturbances. 4. Because of its high accuracy ofpathologic diagnosis and safety, ultrasonography can be regared as the most valuable and preferential study. Butin cases of cystic myomas, endometrioses, cystic missed abortions and huge masses, the accurate diagnoses weredifficult.

BACKGROUND: The Amplified Mycobacterium tuberculosis Direct Test (AMTDT) has been developed for the direct detection of M. tuberculosis complex in respiratory specimens. Traditional methods for diagnosis of extrapulmonary tuberculosis such as the acid-fast bacilli (AFB) stain have their well-known limitations. We investigated the usefulness of the AMTDT for a wide range of non-respiratory specimens to establish early diagnosis of extrapulmonary tuberculosis. METHODS: 346 specimens (219 urine, 117 pleural fluid, 6 ascitic fluid, 2 lymph node, 1 gastric aspirate, and 1 pus specimens) from 340 patients referred from November 1997 to September 1998 were tested by the AMTDT. The AMTDT results were evaluated by comparing with clinical diagnosis and smear results. RESULTS: The overall sensitivity, specificity, and positive and negative predictive values of the AMTDT were 82.9%, 93.8%, 64.2%, and 97.6%, respectively. There were no difference in sensitivity and specificity between pleural fluid and urine specimens. In 31 specimens from tuberculosis patients concurrently tested with AMTDT and stain, 15 were only AMTDT positive and 4 were only stain positive. Among the results considered to be false positive, 47.2% of cases were shown as being less than 150,000 relative light units (RLU). In 30 specimens from tuberculosis patients during or after treatment, all six of the patients with reactivation or aggravation were AMTDT positive, and one case was considered to be false positive. CONCLUSIONS: Our study demonstrates the efficacy of the AMTDT in diagnosing extrapulmonary tuberculosis. Prudent interpretation of the AMTDT's results is recommended in case of that being less than 150,000 RLU.

OBJECTIVE: Closure of a low transverse cesarean incision with one layer and two layer, we compared operative time, hemostasis, blood loss and postoperative sonohysteroperitoneographic findings. Study design: At our hospital 103 women were randomized to closure of a low transverse cesarean incision with either one continuous layer of a locking No. 1 chromic suture or two continuous of No. 1 chromic suture with the first layer locked between Mar. 1, 1998 and Dec. 31, 1998. After three months later, sonhysteroperitoneography was taken and then we evaluated uterus indirectly. RESULTS: A one layer closure required less operative time, 16 versus 20.8 minutes (p<0.01), less hemoglobin change, 0.44 versus 1.3 (p<0.01) and less suture materials (p<0.01). But postoperative follow up sonohysteroperitoneography, a one layer closure shows slightly thinning of isthmic layer of myometrium, two layer closure shows more adhesional band and both are similar other findings. CONCLUSION: A one layer does not significantly affect the clinical course than traditional two layer closure. So we recommended a one layer closure when its use is anatomically feasible.

An antrochoanal polyp is a solitary polypoid mass that arises from the maxillary sinus, and protrudes through the natural ostium into the middle meatus, and reaches the choana, The polyp does not differ histologically from an ordinary nasal polyp, which is composed of edematous, hyperplastic submucosal connective tissue stroma, and is relatively hypocellular, In this sequence of events. Its computed tomographic(CT)findings are characteristic. We retrospectively analyzed CT studies of nine cases, all of which showed similar CT findings; a solitary, homogeneous, hypodense mass without bony destruction that extends from the maxillary sinus through the widened ostium into the choana.

Screening test of Human Immunodeficiency Virus(HIV) infection was introduced on Korean Blood Donor Test Program in July 1987, and the test results between July 1987 and December 1990 were reported on the Korean Journal of Blood Transfusion on May 1992. Moreover, we assessed anti-HIV ELISA screening test result of 3,905,986 blood donors donated at Korean Red Cross Blood Centers between January 1991 and December 1993. The seropositivity of anti-HIV ELISA screening test was 0.26% in 1991, 0.30% in 1992 and 0.18% in 1993.0.15% of all donors in 1991 was reactive repeatedly, and 0.15% in 1992 and 0.08% in 1993. The prevalence of HIV infected donors confirmed by Western Blot Assay was 0.0003% in 1991, 0.0015% in 1992, and 0.0009% in 1993. The sero-positivities of anti-HIV screening tests with AIDSDIA reagent and HIVIRO reagent were 0.32% and 0.17% and the difference was significantly(p<0.05). The sero-positivities of ELISA screening and Western Blot. Assay detecting anti-HIV were lower in soldier group than in non-soldier donor group (p< 0.05).
