Eosinophilic leukemia is a rare variant of granulocytic leukemia. It has distinct clinical features to involve central nervous system, heart, lung and skin more frequently than other leukemia and laboratory findings to reveal persistent eosinophilia with immature tendency, leukocytosis, anernia, thrombocytopenia and usually negative philadelphia chromosome in cytogenetic study. We describe a 33 year-old male patient who has suffered from generalizid weakness exertional dyspnea and has had well defined, hen eggs ized, oval shaped and non-in-durated ulcerative lesions on the right thigh since about 4 months prior to admission. The laboratory findings were persistent leukocytosis, eosinophilia and immature tendency in peripheral blood, nearly 100% cellularity and eosinophilic tendency (70%) in bone marrow aspiration and biopsy, and negative philadelphia chromosome in cytogenetic study. A biopsy specimen from ulcer margin showed relatively intact epidermis and heavy cellular infiltration composed of eosinophilic cytoplasm, dark and indented nucleus in entire dermis. Normal appearing skin also revealed same cellular infiltration in dermis with perivascular and periadnexal pattern.

Crypt glandular infection theory is accepted as an explanation of anal fistula's major cause. However, the pathogenesis of an anal fistula in Crohn's disease is different from that of a conventional anal fistula because a Crohn's anal fistula is caused by ulceration which, in turn, is caused by transmural inflammation of the rectal wall due to Crohn's disease. The difficulty with operating on anal fistulas in Crohn's disease lies in the fact that healing of the wound is inhibited because of continuous inflammation of the anorectal tissue due to Crohn's disease. Hence, there is a high possibility of incontinence due to sphincter muscle injury. Especially, because almost all Crohn's disease patients have frequent defecation and diarrhea, the patients will suffer more if incontinence occurs. Nowadays, even with increased understanding of the etiology of Crohn's disease, new medications, and aggressive surgical approaches, the result of treatment is still not satisfactory. Recently, since Korean eating habits have changed to include more western-style food in the diet, inflammatory bowel disease, such as Crohn's disease, is expected to increase. Consequently, the number of cases of anal fistulas in Crohn's disease is also expected to increase. The authors reviewed 20 confirmed cases of anal fistulas in Crohn's disease, which were treated from January 1993 to December 1995 at Song-Do Colorectal Hospital. The results are as follows: 1) Anal fistulas in Crohn's disease were present in 20(0.6%) of the 3378 cases of anal fistulas treated during the time period considered. 2) The male to female ratio for these 20 cases was 2: 1, and the most Prevalent age group was the 3rd decade, followed by the 2nd decade, the 4th decade, and the 5th decade in that order. 3) Three cases of anal fistulas whose origins could be explained by crypt glandular infection theory and which did not involve the rectum healed, although the healing was delayed. 4) Seventeen cases of anal fistulas whose origins could not be explained by crypt glandular infection theory and which involved the rectum did not heal after the operation. he results of the study show that anal fistulas whose origins can be explanined by crypt glandular infection theory and which do not involve the rectum can be cured by conventional fistula surgery. However, perirectal fistulas whose origins can not be explained by crypt glandular infection theory and which involve the rectum do not heal. Because there is the possibility of incontinence after a conventional operation, it is suggested that, in the cases of perirectal fistulas in Crohn's disease, better results, although not completely satisfactory, can be obtained by long-term seton drainage and diversion colostomy.

Purpose: : This study aims to identify job stress, emotional intelligence, and exhaustion of the nurses in comprehensive nursing service units and then verify the moderating and mediating effects of emotional intelligence on the relationship between job stress and exhaustion. Methods: : Participants are 118 nurses working in two general hospitals. The collected data are analyzed using the SPSS WIN 27.0 and AMOS 18.0 programs by assessing frequency and percentage, mean and standard deviation, independent t-test and one-way ANOVA, Scheffé test, Pearson correlation coefficient, and hierarchical multiple regression analysis and bootstrapping. Results: : Exhaustion has a statistically significant positive correlation with job stress (r=.40, p ＜.001) and a statistically significant negative correlation with emotional intelligence (r=-.26, p =.004). A partial mediating effect of emotional intelligence is found between job stress and exhaustion, however, there is no moderating effect. Conclusion : It is expected that to reduce the exhaustion of nurses in comprehensive nursing service units, it is necessary to assess job stress and emotional intelligence, and strengthen emotional intelligence along with job stress intervention.

BACKGROUND: Local anesthetics are often used for a regional block in patients who are being treated with calcium channel blockers (CCB). Bupivacaine is a local anesthetic with potential for serious cardiovascular toxicity. Ropivacaine is a relatively new local anesthetic. It is clinically equipotent and chemically similar to bupivacaine. Diltiazem (CCB) is a potent coronary and systemic vasodilator with antiarrhythmic properties. Local anesthetics such as bupivacaine and ropivacaine have been suggested to show drug interactions with diltiazem. Therefore, we tried to observe the drug interactions between bupivacaine, ropivacaine and diltiazem using an animal model. METHODS: This study was performed using an isolated rat heart (N = 40) by the Langendorff method. After a stabilization period, all hearts were subjected to the application of local anesthetics of a 1 microgram/ml or 3/ml concentration, respectively. Thereafter, they were subdivided into four groups; the bupivacaine (B) group, bupivacaine with diltiazem (BD) group, ropivacaine (R) group, and ropivacaine with diltiazem (RD) group. Parameters such as, LVP, dp/dt, heart rate (HR), coronary flow (CF), DO2, and MVO2 were measured. RESULTS: All parameters decreased in all groups, respectively (P < 0.05). The BD group and R group showed a lower LVP and dp/dt than those of the B group (P < 0.05). The BD group and B group showed lower HR than that of the R group (P < 0.05). The RD group showed a higher CF than other groups (P < 0.05). CONCLUSIONS: The negative inotropic potency of bupivacaine was enhanced in the presence of diltiazem. We suggest that diltiazem has a protective effect against reduction of CF by ropivacaine. Therefore, we should consider this when selecting local anesthetics for cardiovascular patients under the treatment of diltiazem.
