This study was done to identify the reality in doing the intradermal skin test of injectional antibiotics and to serve a basis to the clinical and educational situations. For the study, the survey was done to the staff nurses who are working at one of the selected 39 hospitals in the capital area, from January 6 to Feburary 8 in 1997. The data analysis was done by mean, standard deviation, Fisher's exact test, t-test, ANOVA through running SAS computer program. The results of the study were as follows : 1.The dilution ratio of the antibiotics was mostly 1 : 10 regardless of what kind of antibitics. Making the contrast was done only for the suspended to the antibiotics. Mostly the reaction was detected after 15 to 20 minutes from its diameter of redness and wheals. Most of the respondents answered they do the intradermal skin test only once for the same antibiotics. 2. In the education on the skin test the 66.7% from the respondents had exposed to the education mostly through the new nurses orientation. The 85.4% from them answered the need of the continuous education which had a significant difference in the number of beds(p=.046). The had experiences of detecting positive reactions(98.3%), and of anaphyaxis(49.5%) which had a significant difference in experience(p=.002) and in their age groups(p=.000). 3. The average score of the confidence on the intradermal skin test was 3.32 form 4-point scale. Also it had a significant difference from the number of beds(p=.010), the year of experiences(p=.016), and their age groups(p=.046). 4. From the general characteristics of respondents, the infection methods had a significant difference in the amounts of injection, whether adopting the contrast pairing, and the repeatable skin tests for the same antibiotics. 5. Only 15 from 39 hospitals had their protocol about the intradermal skin test provided by nursing department which differs in its contents from that provided by the medical information center. From the results of the study, it is suggested that the continuous education on the intradermal skin test and its unified protocol should be provided. Also it is recommended that the drug manufacturer should notice about its anaphylactic cautions and pack its extra skin test use.

This experiment was designed to investigate the histochemical and ultrastructural changes of the proximal tubules and glomeruli of rabbits treated with cyclosporin A (CsA) or cyclosporin A and concomitant administration of prednisolone (PD). Rabbits were given with CsA for 1 week (CsAlW) and for 2 weeks (CsA2W) and CsA plus PD for 1 week (CsA +PDIW) and for 2 weeks (CsA+PD2W). The dose of CsA was 5mg/kg/day i.v. and PD was 1 mg/kg/day i.m. At 1 week and 2 weeks after the treatments, the following items were studied of alkaline phosphatase (ALPase). peroxidase, 5'-nucleotidase (SNU) with the ultrastructural enzymatic changes and electron microscopic changes. CsAlW, CsA2W and CsA +PD2W groups showed a decrease of ALPase activity and CsA+PD2W and CsA2W groups showed weakly increased peroxidase activity CsA2W and CsA+PD2W showed a decrease of 5NU activity. Ultrastructural changes of CsAlW CsA2W and CsA+PD2W groups revealed swollen and disrupted mitochondria, loss of brush border in the proximal tubules and thickening of basement membranes, edematous podocytes and fusion of root processes of podocytes in the glomeruli showing the early stage of nephrotoxicity. The concomitant treatment of PD with CsA eased the nephrotoxicity of CsA within 1 week after the treatment.

This study examined effect of preceptorship on clinical education of senior nursing students of Y. University in Seoul. Quasi-experimental study design was used. Sixty students of pre-test and 80 of post-test participated in this study. Competency scores of the students before the clinical education(pre-competency scores) were compared with the competency scores after the clinical education(post-competency scores), and teacher evaluation scores between preceptors and clinical the data from students with preceptors(experimental group, N=22) and with clinical instructors(comparative group, N=58) were also examined. Study results indicated that the total post-competency scores were higher compared to the total pre-competency scores, and the difference was statistically significant. Among 7 sub-domains, differences were all statistically significant in 6 sub-domains except "self-esteem" domain. Competency scores of the students who had clinical education with had clinical education from clinical instructors. But the difference between those scores was not statistically significant. However, students gave higher evaluation scores to preceptors than clinical instructors. This study concluded that preceptorship did not influence much on clinical education at this time yet. However it is expected that when preceptors adjust their new roles and function them in expert education. This study recommended that for the preceptors to increase their motivation to teach students and to accept their roles, systemic rewards are needed.

Purpose: Renin-angiotensin system (RAS) is involved in the pathophysiology of colonic inflammation. The aim of this study was to investigate whether small angiotensins (Angs) peptides play a role in the regulation of colonic motility and their roles are modulated in colitis. Methods: Experimental colitis was induced by an intake of 5% dextran sulfate sodium (DSS) dissolved in tap water for 7 days in Sprague-Dawley rats. After sacrifice, plasma hormone concentrations and messenger RNAs (mRNAs) for RAS were measured. Functional analysis of colonic motility in response to Angs peptides was performed using Taenia coli. Results: DSS-treated colon showed an increased necrosis with massive infiltration of inflammatory cells. The mRNA level of colonic angiotensin II receptor type 2 (AT2R) in DSS-treated rats was higher than that in control rats whereas the mRNA levels of angiotensin II converting enzyme (ACE), ACE2, AT1R, AT4R, and Mars receptor were not different from those in control rats. Ang III, Ang IV, and Ang-(1-9) (1, 3 μM) increased the frequency of basal colonic motility. Ang-(1-7) did not cause any significant changes in frequency and amplitude of basal motility. The order of potency for an increased frequency of basal motility seems to be Ang II>>Ang IV>Ang III=Ang-(1-9). The increased frequency of basal motility by Ang-(1-9) but not Ang IV was significantly enhanced in DSS-treated rat colon. Conclusion In conclusion, these data suggest that small Angs peptides are partly involved in the pathophysiological regulation of colonic motility in experimental colitis.

PURPOSE: To analyze the effect of treatment of unstable intertrochanteric fractures with dynamic hip screw and additional trochanter stabilizing plate. MATERIALS AND METHODS: Among twenty three cases of unstable intertrochanteric fractures treated with DHS and additional TSP between January 2002 to December 2004, seventeen cases over sixty years old were reviewed with minimal follow up of one year. We analyzed the type of fracture by AO classification, the age of patient, sex, the cause of trauma in seventeen cases. We evaluated the lag screw slippage, the change of neck-shaft angle and lateral displacement of greater trochanter, the period of union by comparison of last follow up radiographs with immediate postoperative radiographs. The fixation failure is defined that displacement of lag screw tip is more than 3 mm or cut out of the screw from the femoral head. RESULTS: The period of union was average 12.8 weeks. The lag screw slippage was average 8.22 mm. The change of neck-shaft angle was average 2.66 degree. No lateralization of greater trochanter was noted in twelve cases, but five cases showed average 0.8 mm (range: 0.5~1 mm) of lateral displacement of greater trochanter. There was not fixation failure. CONCLUSION: In unstable intertrochanteric fracture, the addition of a TSP to the dynamic hip screw can decrease a change of neck shaft angle, a lag screw slippage, and prevent lateral displacement of greater trochanter.

PURPOSE: To determine the frequency and distribution of parenchymal changes on mammography before and after hormone replacement therapy. MATERIALS AND METHODS: Mammograms of 100 postmenopausal women who underwent hormone replacement therapy without breast disease were evaluated. Mammograms obtained annually after hormone replacement were analysed and compared with that of pretreatment. In addition, mammograms of control group and treatment group were compared. RESULTS: An increase in density of breast parenchyma was seen on the mammogram of 20 women(20%) receiving therapy. The mammograms from the control group showed no change. Mammographic changes were detected at first year in 13 women, 2nd year in 4 women, 3rd year in 2 women, and 4th year in 1 woman (average,19 months). CONCLUSION: We conclude that increase in mammographic density following postmenopausal hormone replacement therapy is not uncommon(20%).

THE AIM OF STUDY: The transseptal-transsphenoidal approach (TSA) for pituitary tumors may alter nasal functions, including nasal respiration and olfaction. The aim of this study was to investigate the efficacy of TSA in terms of nasal functions. MATERIALS AND METHODS: Twenty two cases of pituitary tumors, managed at Seoul National University Hospital from May 1997 through March 1998, were included in this prospective study. Nasal functions were evaluated preoperatively and 2 months after the operation through symptom questionnaires, rhinomanometry, acoustic rhinometry and the butanol thres-hold test. RESULTS: The subjective nasal symptoms, including nasal obstruction and olfaction, were not changed following the operation in 72% and 86% of the cases, respectively. In the objective findings, total nasal resistance was not grossly changed after the operation, however, cross-sectional areas at C-notch and 3.3 cm from the anterior nasal spine increased significantly after the operation. Mucosal response to a topical vasoconstrictor after the operation was less effective than before the preoperation. CONCLUSION: TSA for pituitary tumors may be a safe and effective technique in preserving nasal functions subjectively and objectively.

The existing term non-alcoholic fatty liver disease (NAFLD) has raised substantial concerns due to its inherent disadvantages of using exclusionary diagnostic criteria and the stigmatizing word ‘fatty.’ Three pan-national liver associations set out to explore a new nomenclature to replace both NAFLD and its suggested alternative, metabolic (dysfunction)-associated fatty liver disease (MAFLD). They surveyed if a change in nomenclature and/or definition is favored and which nomenclature best communicates disease characteristics and increases awareness. In lieu of NAFLD/MAFLD, metabolic dysfunction-associated steatotic liver disease (MASLD) has been chosen, and an umbrella term, steatotic liver disease (SLD), encompassing the whole spectrum of liver disease, has been proposed. It has been suggested that cardiometabolic risk factors should be considered when categorizing SLD patients. Furthermore, a new subcategory, MASLD with increased alcohol intake (MetALD), casts light on a neglected group of patients with moderate or more alcohol consumption. The importance of metabolic dysfunction was acknowledged in this new nomenclature, but the precise contribution of metabolic dysfunction and alcohol consumption to the development and progression of SLD remains unclear. Herein, we review hepatologists’ and endocrinologists’ perspectives on the new nomenclature, along with its possible impact on clinical practice. Although it is premature to predict the settlement of the new nomenclature, this review may help build more evidence for a soft landing of it in the future.
