We have recently experienced a case of cysticercosis treated with praziquantel. The patient, 22-year-old female, with 43 cystic masses had marked clinical response to the administration of praziquantel (75 mg/kg/day) for 7 days. It seems that praziquantel, anticestodal agent, might be a safe and effective therapy for this infection.

BACKGROUND: Skin contact with metalworking fluid(MWF) remains a frequent cause of occupational dermatitis. However, no precise data is available about sensitization in metalworkers exposed to MWF in Korea. OBJECTIVES: The purpose of this study was to evaluate the prevalence of contact sensitivity among metalwokers who handle MWFs and to investigate the suitability of a screening test with MWFs being actually used in metalworkers. METHODS: An epidemiological study was performed using a'questionnaire in 771 workers in 9 derpartments of a motor company. 278 out of 771 workers had actual contact with MWF. Patch tests were performed in 73 metalworkers who had suspected dermatits in relation to exposure of MWF, which was selected via interviews and dermatologic examinations. Patch tests were included with a routine series of common components of MWF(materials obtained from Chemotechnique, Sweden), a solvent series and several dilutions of various crude MWFs(8 species) RESULTS: Contact sensitization was established in 14 metalworkers(5% of 278). Sensitising substances were biocide(6 cases), corrosion inhibitors(2 cases), emulsifiers(2 cases), biostatic substances(1 cses) and others(4 cases). Therefore 10 out of 14 metalworkers had true occupational allergic contact dermatitis. 10 out of 73 screening patch tests showed positive reactions to MWF elements, and 9 people who were positive to MWF elements showed positive reactions to crude MWF, but 1 person did not. CONCLUSION: The prevalence of occupational allergic contact dermatitis(3.5% of 278) was low. The screening patch test by crude MWFs actually used in metalworkers may give false negatives. Therefore for the purpose of diagnosis of allergic contact dermatitis, we need a process of patch tests with MWF elements.

BACKGROUND: Although the effect of clonidine, an alpha2 adrenoreceptor agonist, is well established, there is no study to evaluate the effects of addition of clonidine to ldegrees Cal anesthetics in elderly hypertensive patients. The aim of this study is to evaluate the effects of addition of clonidine to ldegrees Cal anesthetics in elderly hypertensive patients undergoing senile cataract surgery. METHODS: Forty elderly hypertensive patients who scheduled for elective senile cataract surgery were divided into two groups. The control group (n=20) received oral diazepam 0.1 mg/kg 60 min before surgery and the clonidine group (n=20) did not received premedication. A mixture of 2% liddegrees Caine and 0.5% bupivacaine with normal saline 0.7 ml (control group) or clonidine 100 ug (clonidine group) was used as a ldegrees Cal anesthetics. Perioperative blood pressure, heart rate, sedation score, and intradegrees Cular pressure were measured. RESULTS: After anesthesia, there was a significant fall in blood pressure and intradegrees Cular pressure in clonidine group, and increase in sedation score in clonidine group than control group. There was no difference in the perioperative heart rate between the two groups. CONCLUSIONS: The above results show that addition of clonidine to ldegrees Cal anesthetics in elderly hypertensive patients undergoing senile cataract surgery produced reduction in blood pressure, intradegrees Cular pressure and produced intraoperative sedation.

BACKGROUND: The cryopreservation of red blood cells (RBCs) has not ever been applied to the clinical services in Korea. The aim of this study was designed to supply the frozen-thawed RBCs as a routine service through estimation of efficiency and safety after freezing, thawing and washing. METHODS: Fifteen fresh packed RBCs were frozen with 40 percent(wt/vol) glycerol. After frozen storage at -70degrees for at least one month, the RBCs were thawed and washed in the COBE 2991 blood cell processor. We measured the blood cell count, RBC recovery rate, K+, LDH, specific gravity, osmolarity, and the percentage of hemolysis in the supernatant after deglycerolization. Autologous transfusions were done to the four voluntary donors with deglycerolized autologous blood for clinical assessment. RESULTS: The freeze-thaw-wash recovery rate of RBC was 76.8+/-10.0%, which is not enough to pass the AABB standard. But the recovery rate was increased up to 87.0+/-2.1% with the 4 stepwise predilution technique. The supernatant plasma specific gravity, osmolarity, and K+ were 1.006+/-0.001, 292+/-3 mOsm/KgH20, and 1.1+/-0.2mEq/L, respectively. The Hb ATP and 2,3-DPG were 3.6+/-0.8nmol/g and 13.4+/-4.5nmol/g. In simulated study, the free hemoglobin was 2.8+/-1.1mg/dL and 0.4+/-0.2% of total hemoglobin. In four autologous transfusion cases, plasma haptoglobin level was 96.0+/-40.8 mg/dL (reference range 30~200 mg/dL) and urine hemoglobin was not observed after 2~6 hours later after transfusion. CONCLUSION: The results of this study indicated that technical experiences for freezing, thawing and washing were established for clinical use of frozen RBCs in Korea.

BACKGROUND: The hemodynamic superiority of total cavopulmonary anastomosis (TCPA) over atriopulmonary connection as a modification of Fontan-type operation, began to be acknowledged with more applications to clinical cases. The need of adequate resolutions for the investigation and improvement of residual hemodynamic derangements including abnormal distribution of the pulmonary blood flow, is emerging. METHODS: We studied 20 patients (M:F=12:8, age:67.9+/-41.5 months) who have had the TCPA and were followed-up by cardiac catheterization, angiography and lung perfusion scan 24.5+/-15.7 months after the operation. Pulmonary arterial growth and hemodynamic influences including the pulmonary blood flow distribution were investigated to verify the appropriateness of the conventional TCPA method and to aid in the determination of the consequences and prognosis of the operation. RESULTS: The mean pulmonary arterial pressure before and after the operation was 15.1+/-3.2 mmHg and 13.9+/-4.8 mmHg respectively without significant difference and there was no significant postoperative changes in the cross-sectional area index of pulmonary artery in regard to the variability of body surface area. The pulmonary blood flow was distributed with a greater amount in the ipsilateral side of IVC flow entrance (IVCipsi) than the contralateral side (IVCcontra), with an ipsilateral to contralateral perfusion ratio (i/cPR) of 1.24+/-0.42. Comparing the subgroups by the type of superior vena caval inflow, unilateral superior cavopulmonary anastomosis (SCPA) group showed significantly higher i/cPR (1.47+/-0.33) than the bilateral SCPA group (1.07+/-0.21). Comparing the subgroups by the type of IVC inflow, the i/cPR of the intraatrial tunnel group was higher than the hemiazygous continuation group, but there was no statistical significance. CONCLUSION: TCPA does not influence the growth of pulmonary artery, and the type of cavopulmonary anastomosis and the bilaterality of superior vena cava may have major influences on the distribution of the pulmonary blood flow. The details of surgical methods should be evaluated case by case in respect to the associated anomalies in order to achieve adequate postoperative pulmonary blood flow distribution.

It has been thought for many years that gastric adenocarcinoma almost never crosses the pylorus. Although this theory was generally accepted, several studies have refuted it. We report three cases of gastric adenocarcinoma direct spreading into the duodenum that was diagnosed by endoscopic duodenal biopsy and review the literature.
